We combine judgment and experience with data-driven analysis, enhancing our overall risk selection process.
We modulate our risk appetite and deployment of capital across the underwriting cycle, commensurate with available market opportunities and returns: Closely attunedIn response to market dynamics, we recognize opportunities as they develop and react quickly as new trends emerge. Our risk analytics provide important and continuous feedback, further assisting with the ongoing assessment of our risk appetite and strategic capital deployment.

We nurture an ethical, risk-aware, achievement-oriented culture that promotes professionalism, responsibility, integrity, discipline and entrepreneurship. As a result, we believe that our staff is well-positioned to make the best underwriting and strategic decisions for the Company.
OurIn 2019, our key metrics for performance measurement include annual non-GAAPincluded operating return on average common equity ("non-GAAP operating ROACE") which is reconciled to the most comparable GAAP financial measure, return on average common equity ("ROACE"), in the Item 7 'Management's'Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") -Executive Summary' – Results of Operations' on an annual basis and diluted book value per diluted common share adjusted for dividends over the long-term.

Competitive Environment
In our reinsurance segment, competition tends to be focused on availability, service, financial strength and, increasingly, price. We compete with major U.S. and non-U.S. reinsurers and reinsurance departments of numerous multi-line insurance organizations. In addition to traditional market participants, we also compete with new market entrants supported by alternative capital sources offering risk transfer solutions on a collateralized or other non-traditional basis. Our clients may also acquire reinsurance protection through capital market products such as catastrophe bonds and insurance loss warranties. We believe that we achieve a competitive advantage through our diversified global product offering, responsiveness to customer needs and ability to provide sophisticated and innovative products. We offer excellent claims management, strong financial strength ratings and an ability to leverage our own balance sheet and relationships with strategic capital partners to provide meaningful capacity.
 



CASH AND INVESTMENTSCash and Investments
We seek to balance the investment portfolios’ objectives of (1) increasing book value with (2) the generation of relatively stable investment income, while providing sufficient liquidity to meet our claims and other obligations. Liquidity needs arising from potential claims are of primary importance and are considered in asset class participation and the asset allocation process. Intermediate maturityA significant portion of the investment portfolio is dedicated to investment grade fixed income securities have duration characteristics similar to ourmaturities that will generate cash flows that match expected claim payouts and are, therefore, central to our investment portfolio’s asset allocation. At December 31,2017, the duration of our fixed maturities portfolio was approximately 3 years, which approximates the estimated duration of our net insurance liabilities.payouts.
To diversify risk and optimize the growth in our book value, we may invest in other asset classes such as equity securities, high yield securities and alternative investments (e.g. hedge funds) which provide higher potential total rates of return. SuchThese individual investment classes involve varying degrees of risk, including the potential for more volatile returns and reduced liquidity. However, as part of a balanced portfolio, they also provide diversification from interest rate and credit risk.
With regard to our investment portfolio, we utilize third partythird-party investment managers for security selection and trade execution functions, subject to our guidelines and objectives for each asset class. This enables us to actively manage our investment portfolio with access to top talentsperformers specializing in various products and markets. We select the managers based on various criteria including investment style, performance history and corporate governance. Additionally,In addition, we monitor approved investment asset classes for each subsidiary through analysis of our operating environment, including expected volatility of cash flows, overall capital position, regulatory and rating agency considerations. The Finance Committee of our Board of Directors approves our overall group asset allocation targets and investment policy to ensure that they are consistent with our overall goals, strategies and objectives. We also have an Investment and Finance Committee, comprising senior management, which oversees the implementation of our investment strategy.

RISK AND CAPITAL MANAGEMENT

Risk Management Framework – Overview
Mission and Objectives
The mission of Enterprise Risk Management ("ERM") at the Company is to promptly identify, measure, report and monitor risks that affect the achievement of our strategic, operational and financial objectives. The key objectives of our risk management framework are to:
 
Protect our capital base and earnings by monitoring our risks against our stated risk appetite and limits;
Promote a sound risk management culture through disciplined and informed risk taking;
Enhance value creation and contribute to an optimal risk-return profile by providing the basis for efficient capital deployment;
Support our group-wide decision makingdecision-making process by providing reliable and timely risk information; and
Safeguard our reputation.
Risk Governance
At the heart of our risk management framework is a governance process with responsibilities for taking, managing, monitoring and reporting risks. We articulate the roles and responsibilities for risk management throughout the organization, from the Board of Directors and the Chief Executive Officer to our business and functional areas, thus embedding risk management throughout the business (see(refer to 'Risk governanceGovernance and risk management organizationRisk Management Organization') below).
To support our governance process, we rely on our documented policies and guidelines. Our Risk Policiesrisk policies are a formal set of documents we use to specify our approach and risk mitigation / mitigation/control philosophy for managing individual and aggregate risks. We also have procedures to approve exceptions and procedures for referring risk issues to senior management and the Board of Directors. Our qualitative and quantitative risk reporting framework provides transparency and early warning indicators to senior management with regard to our overall risk profile, adherence to risk appetite and associated limits, and improvement actions both at an operating entity and Group level.
Various governance and control bodies coordinate to help to ensure that objectives are being achieved, risks are identified, and appropriately managed, and internal controls are in place and operating effectively.
Internal Capital Model
An important aspect of our risk management framework is our internal capital model. Utilizing this modeling framework provides us with a holistic view of the capital we put at risk in any year by allowing us to understand the relative interaction among the known risks impacting us. This integrated approach recognizes that a single risk factor can affect different sub-portfolios and that different risk factors can have different mutual dependencies. We continuously review and update our model and its parameters as our risk landscape and external environment continue to evolve.

As well as being used to measure internal risk capital (see(refer to 'Capital Management')below), our internal capital model is used as a tool in managing our business, and for strategic planning via capital allocations, and through to portfolio monitoring, reinsurance and retrocession (collectively referred to as "reinsurance") purchasing, and investment asset allocations.
Our internal capital model is an integral part of the business planning process which provides an assessment as to whether our prospective business and investment strategies are in line with our defined risk appetite and objectives, at both the group and operating entity level. The model also provides a basis for optimizing our risk-return profile by providing consistent risk measurement across the Group. The model outputs are reviewed and supplemented with management’s judgment and business experience and expertise.
Risk Diversification
As a global (re)insurer and reinsurer with a wide product offering across different businesses, diversification is a key component of our business model and risk framework. Diversification enhances our ability to manage our risks by limiting the impact of


a single event and contributing to relatively stable long-term results and our general risk profile. The degree to which the diversification effect can be realized depends not only on the correlation between risks but also the level of relative concentration of those risks. Therefore, our aim is to maintain a balanced risk profile without any disproportionately large risks. Our internal capital model considers the level of correlation and diversification between individual risks and we


measure concentration risk consistently across our business units in terms of pre and post diversified internal risk capital requirements.
Risk Appetite and Limit Framework
Our integrated risk management framework considers material risks inthat arise from operating our business either from investments, underwriting or operations.business. Large risks that might accumulate and have the potential to produce substantial losses are subject to our globalgroup-wide risk appetite and limit framework. Our risk appetite, as authorized by our Board of Directors, represents the amount of risk that we are willing to accept within the constraints imposed by our capital resources as well as the expectations of our stakeholders as to the type of risk we hold within our business. At an annual aggregated level, we also monitor and manage the potential financial loss from the accumulation of risk exposure in any one year.
Specific risk limits are defined and translated into a consistent framework across our identified risk categories and across our operating entities and are intended to limit the impact of individual risk types or accumulations of risk. Individual limits are established through an iterative process to ensure that the overall framework complies with our group-wide requirements on capital adequacy and risk accumulation.
We monitor risk through, for example, risk dashboards and limit consumption reports. These are intended to allow us to detect potential deviations from our internal risk limits at an early stage.
External Perspectives

Various external stakeholders, among them regulators, rating agencies, investors and accounting bodies, place emphasis on the importance of sound risk management in the insuranceinsurance/reinsurance industry. We monitor developments in the external environment and evolve our risk management practices accordingly.
Risk Governance and Risk Management Organization
The key elements of our governance framework, as it relates specifically to risk management, are described below.

Board of Directors’ Level


The Risk Committee of the Board ("Risk Committee") assists the Board of Directors in overseeing the integrity and effectiveness of our enterprise risk managementERM framework and ensuring that our risk assumption and risk mitigation activities are consistent with that framework. The Risk Committee reviews, approves and monitors our overall risk strategy, risk appetite and key risk limits and receives regular reports from the Group Risk Management function ("Group Risk") to ensure any significant risk issues are being addressed by management. The Risk Committee further reviews, with management and Internal Audit, the Group’s general policies and procedures and satisfies itself that effective systems of risk management and controls are established and maintained. Among its other responsibilities, the Risk Committee also reviews and approves our annual Own Risk and Solvency Assessment ("ORSA") report. The Risk Committee assesses the independence and objectivity of our Group Risk function, approves its terms of reference and reviews its ongoing activities.

Following a recommendation by the Chief Executive Officer, the Risk Committee also conducts a review and provides a recommendation to the Board of Directors regarding the appointment and/or removal of the Chief Risk and Actuarial Officer. The Risk Committee meets with the Chief Risk and Actuarial Officer in separate executive sessionsessions on a regular basis.
The Finance Committee of our Board oversees the Group’s investment of funds and adequacy of financing facilities. This includes approval of the Group’s strategic asset allocation plan. The Audit Committee of our Board, which is supported by our internal audit function, is responsible for overseeing internal controls and compliance procedures, and also reviews with management and the Chairman of the Risk Committee, the Group’s guidelines and policies regarding risk assessment and risk management.



Group Executive Level
Our management Executive Committee formulates our business objectives and risk strategy within the overall risk appetite set by our Board. It allocates capital resources and sets limits across the Group, with the objective of balancing return and risk. While the management Executive Committee is responsible overall for risk management, it has delegated some authority to the executive level Risk Management Committee ("RMC"): consisting of the Chief Executive Officer, Chief Financial Officer, Chief Strategy Officer, Chief Underwriting Officer, Chief Executive Officers of each segment, Chief Risk Officer, Chief Actuary and General Counsel.

The RMC is responsible for overseeing the integrity and effectiveness of the Group's ERM framework and ensuring that the Group's risk assumption and risk mitigation activities are consistent with that framework, including a review of the annual business plan relative to our risk limits. In addition to the RMC, there is an established framework of separate yet complementary management committees and subcommittees, focusing on particular aspects of ERM including the following:

Management Committees
The Business Council oversees underwriting strategy and performance, establishes return targets, and manages risk/exposure constraints across each line of business, in line with the Company’s strategic goals.
The Product Boards for each major line of business aim to develop a coherent strategy for portfolio management, set underwriting guidelines and risk appetite, and leverage expertise across the multiple geographies that we operate in. The boards also oversee exposure management frameworks and view of risk.
The Investment & Finance Committee oversees the Group’s investment activities by, among other things, monitoring market risks, the performance of our investment managers and the Group’s asset-liability management, liquidity positions and investment policies and guidelines. The Investment & Finance Committee also prepares the Group’s strategic asset allocation and presents it to the Finance Committee of the Board for approval.

The Capital Management Committee oversees the integrity and effectiveness of the Company’s Capital Management Policy, including the capital management policies of the Company’s legal entities and branches, and oversees the availability of capital within the Group.
The Group Reserve Committee ensures appropriate oversight and challenge of the Group and Segment Reserves, led by the Group Chief Reserving Actuary.
RMC Sub-Committees
The Reinsurance Security Committee ("RSC") sets out the financial security requirements of our reinsurance counterparties and approves reinsuranceour counterparties, as needed.

The Cyber Enterprise Product Board oversees and facilitates the Group's Risk framework for the identification, management, mitigation and measurement of cyber risk exposures. It facilitates the embedding of effective risk management practices for cyber exposures throughout the Company, based on currently available information. 

The Internal Model Committee oversees the Group's Internal Model framework, including the key model assumptions, methodology and validation framework.

The Operational Risk Committee oversees the Group's Operational Risk framework for the identification, management, mitigation and measurement of operational risk and facilitates the embedding of effective operational risk management practices throughout the Group.

The Emerging Risks CommitteeWorking Group oversees the processes for identifying, assessing and monitoring current and potential emerging risks.
Group Risk Management Organization
As a general principle, management in each of our business units is responsible in the first instance for both the risks and returns of its decisions. Management is the 'owner' of risk management processes and is responsible for managing our business within defined risk limits.
Our Chief Risk and Actuarial Officer reports to the Group Chief ExecutiveFinancial Officer and the Chairman of the Board Risk Committee, leads our independent Group Risk function, and is responsible for oversight and implementation of the Group's ERM framework as well as providing guidance and support for risk management practices. Group Risk is responsible for developing methods and processes for identifying, measuring, managing and reporting risk. This forms the basis for informing the Risk Committee and RMC of the Group’s risk profile. Group Risk develops our risk management framework and oversees the adherence to


this framework at the Group and operating entity level. Our Chief Risk and Actuarial Officer regularly reports risk matters to the Chief ExecutiveFinancial Officer, ("CEO"), management Executive Committee, RMC and the Risk Committee.
Internal Audit, an independent, objective function, reports to the Audit Committee of the Board on the effectiveness of our risk management framework. This includes assurance that key business risks have been adequately identified and managed appropriately and that our system of internal control is operating effectively. Internal Audit also provides independent assurance around the validation of our internal capital model and coordinates risk-based audits, compliance reviews, and other specific initiatives to evaluate and address risk within targeted areas of our business.
Our risk governance structure is further complemented by our Legal Departmentlegal department which seeks to mitigate legal and regulatory compliance risks with support from other departments. This includes ensuring that significant developments in law and


regulation are observed and that we react appropriately to impending legislative and regulatory changes and applicable court rulings.
Risk Landscape
Our risk landscape comprises strategic, insurance, credit, market, operational, liquidity and other risks that arise as a result of doing business. We provide definitions of these risk categories in the following sections as well as our related risk management. Across these risk categories, we identify and evaluate emerging threats and opportunities through a framework that includes the assessment of potential surprise factors that could affect known loss potentials.
Our risk landscape is reviewed on a regular basis to ensure that it remains up-to date based on the evolving risk profile of the Company. In addition, we undertake ongoing risk assessments across all enterprise risks, capturing and reviewingthe output of which is captured in our risk register outputswhich is reviewed and reported through our governance structures.structure.
Strategic Risk
Strategic risks are risks that affect or are created by an organization’s business strategy and strategic objectives. Our review of strategic risk is the risk of loss arising from the adverse effect of management decisions on both business strategies and their implementation. This includes the failure to devise or adapt a business strategy in light of changes in ourbroad one that evaluates not only internal and external environment.challenges that might cause our chosen strategy to fail but also evaluates major risks that could affect our long-term position and performance. We assess anybelieve it is imperative that, when we develop a strategy, we think about the business risks associated with that strategy and that we think about the business risks that are minimized by following a particular strategy. We also view strategic actionrisk not only as the negative impact of risk but also the sub-optimization of gain. Fundamentally, we believe that if we figure out both the value protection and the value creation part of risk we are set up for success.
A strategy function was formed as part of our enterprise-wide transformation to ensure that the prioritization and coordination of enterprise-wide resources is done efficiently and effectively to drive targeted strategic outcomes. On no less than a quarterly basis, the Executive Committee of the Company meets and receives holistic information about execution against strategy and makes decisions to adjust and/or advance strategy. In addition, strategies employed throughout our business units, in support of the broader enterprise strategy, are reviewed in the context of our risk frameworka broader governance structure, by reviewing the impact of the strategy, including any incremental risk, prior to the action taking place. Additionally, what we learn about risk through our monitoring, reportingBusiness Council and control processes provides important feedback in terms of reevaluating our risks and, therefore, reevaluating our business strategy.
We undertake a strategic business planning process on an annual basis which is overseen by our management Executive Committee, business unit leadership and ourare ultimately approved by the Board of Directors. Our internal capital model provides an input into this process by providing an assessment as to whether our prospective business and investment strategies are in line with our defined risk appetite and objectives, at both the group and operating entity level. The model also provides a basis for optimizing our risk-return profile by providing consistent risk measurement across the Group. The model outputs are reviewed and supplemented with management’s judgment and business experience and expertise.
We specifically evaluate the risks of potential merger and acquisition transactions both from a quantitative and qualitative perspective. We conduct risk assessments of merger and acquisition transactions to evaluate risks specifically related to the integration of acquiring a business. Additionally, we have governance procedures in place to review and approve strategic investments and potential new initiatives within our existing businesses in order to evaluate whether the risks are well understood and justified by the potential rewards.
Insurance Risk
Insurance risk is the inherent uncertainty as to the occurrence, amount and timing of insurance and reinsurance liabilities transferred to us through the underwriting process.
Since our inception in 2001, we have expanded our international presence, with underwriting offices in Bermuda, the U.S., Europe, Singapore, Canada and Canada.the Middle East. Our disciplined underwriting approach coupled with a group-wide peer review process has enabled us to manage this growth in a controlled and consistent manner.
A key component of the Group's underwriting risk governance is our peer review processes which allow for a collaborative review of risk and pricing and ensures that underwriting is within established protocols and guidelines. Underwriting guidelines are in place to provide a framework for consistent pricing and risk analysis and ensuring alignment to the Group's risk appetite. Limits are set on underwriting capacity, and cascade authority to individuals based on their specific roles and expertise.
We also have significant audit coverage across our business units, including Management Initiated Audits ("MIAs"). MIAs are audits of underwriting and claims files performed by teams independent of those who originated the transactions, the


purpose of which is to test the robustness of our underwriting, claims and operating processes and to recognize any early indicators of future trends in our operational risk environment.




Reinsurance Purchasing
Another key component of our mitigation of insurance risk is the purchase of reinsurance on both a treaty (covering a portfolio of risks) and facultative (single risk) basis, on both our short and long tail lines of business.
For treaty reinsurance, we purchase both proportional and non-proportional cover. Under proportional reinsurance, we cede an agreed proportion of the premiums and the losses and loss adjustment expenses on the policies we underwrite. We primarily use proportional reinsurance on our liability, and professional lines, portfolio,and cyber portfolios, as well as on select property portfolios, whereby we protect against higher loss frequency rather than specific events. We also purchase proportional reinsurance on our assumed property catastrophe reinsurance portfolio, casualty, and credit and bond portfolios, which includes cessions to our Strategic Capital Partners. We also use non-proportional reinsurance, whereby losses up to a certain amount (i.e. our retention) are borne by us. UsingBy using non-proportional reinsurance, we can limit our liability with a retention, which reflects our willingness and ability to bear risk, and therefore in line with our risk appetite. We primarily purchase the following forms of non-proportional reinsurance:
 
Excess of loss per risk – the reinsurer indemnifies us for loss amounts of all individual policies effected, defined in the treaty terms and conditions. Per risk treaties are an effective means of risk mitigation against large single losses (e.g. a large fire claim). This includes the Northshore Re catastrophe bond program, which provides a combined $715 million of limit across the Group. Refer to Item 7 'Management’s Discussion and Analysis of Financial Condition and Results of Operations' – Underwriting Results – Consolidated – Underwriting Expenses' for further details.
Excess of loss per risk – the reinsurer indemnifies us for loss amounts of all individual policies effected, defined in the treaty terms and conditions. Per risk treaties are an effective means of risk mitigation against large single losses (e.g. a large fire claim).


Catastrophe excess of loss – provides aggregate loss cover for our insurance portfolio against the accumulation of losses incurred from a single event (e.g. windstorm).


We have a centralized Ceded Reinsurancerisk funding department, which coordinates external treaty reinsurance purchasing across the Group and is overseen by our Reinsurance Purchasing Group ("RPG"). The RPG, which includes among others, our Chief Executive Officer, Chief Financial Officer, Chief Risk and Actuarial Officer and business unit leadership, approves each treaty placement, and aims to ensure that appropriate diversification exists within our RSC approved counterparty panels.

Facultative reinsurance is case by case risk transfer, which we may also use to complement treaty reinsurance by covering additional risks above and beyond what is already covered in treaties. Facultative reinsurance is monitored by the Ceded Reinsurancerisk funding department.
Natural Peril Catastrophe Risk
Natural catastrophes such as hurricanes and windstorms, earthquakes, storms, tsunamistornados and floods represent a challenge for risk management due to their accumulation potential and occurrence volatility. In managing natural catastrophe risk, our internal risk limit framework aims to limit both the loss of capital due to a single event and the loss of capital that would occur from multiple (but perhaps smaller events) in any year. Within this framework, we have an established risk limit for single event, single zone probable maximum loss ("PML") within defined zones and at various return periods. For example, at the 1-in-250 year1-in-250-year return period, we are not willing to expose more than 25%20% of our prior quarter-end common-equity from a single event within a single zone.



The table below shows our mean PML estimates for certain defined single zones which correspond to peak industry catastrophe exposures at January 1, 20182020 and 2017:2019:

The return period refers to the frequency with which losses of a given amount or greater are expected to occur. A zone is a geographic area in which the insurance risks are considered to be correlated to a single catastrophic event. Estimated losses from a modeled event are grouped into a single zone, as shown above, based on where the majority of the total estimated industry loss is expected to occur. In managing zonal concentrations, we aim to ensure that the geography of single events is suitably captured, but distinct enough that they track specific types of events. For example, our definition of Southeast wind encompasses five states, including Florida, while our definition of Gulf Wind encompasses four states, including Texas.
Our PMLs take into account the fact that an event may trigger claims in a number of lines of business. For instance, our U.S. hurricane modeling includes the estimated pre-tax impact to our financial results arising from our catastrophe, property, engineering, energy, marine and aviation lines of business. Our PMLs include assumptions regarding the location, size and magnitude of an event, the frequency of events, the construction type and a property’s susceptibility to damage, and the cost of rebuilding the property. Loss estimates for non-U.S. zones will be subject to foreign exchange rates, although we may mitigate this currency variability from a book value point of view.perspective.
As indicated in the table above, our modeled single occurrence 1-in-100 year1-in-100-year return period PML for a Southeast U.S. hurricane, net of reinsurance, is approximately $0.4$0.3 billion. According to our modeling, there is a one percent chance that on an annual basis, our losses incurred from a Southeast hurricane event could be in excess of $0.4$0.3 billion. Conversely, there is a 99% chance that on an annual basis, the loss from a Southeast hurricane will fall below $0.4$0.3 billion.
We have developed our PML estimates using multiple commercially available vendor models, including AIR Worldwide ("AIR") and Risk Management Solutions ("RMS") (which, which we also use for pricing catastrophe risk).risk. These models cover the major peril regions where we face potential exposure. We combine the outputs of catastrophe models with our estimate of non-modeled perils and other factors which we believe, from our experience, provides us with a more complete view of natural peril catastrophe risk.
Our PML estimates are based on assumptions that are inherently subject to significant uncertainties and contingencies. These uncertainties and contingencies can affect actual losses and could cause actual losses to differ materially from those expressed above. We aim to reduce the potential for model error in a number of ways, the most important of which is by ensuring that management’s judgment supplements the model outputs. We also perform ongoing model validation both within our business units and at a group level including through our catastrophe model validation unit. These validation procedures include sensitivity testing of models to understand their key variables and, where possible, back testing the model outputs to actual results.
Our estimatedEstimated net losses from peak zone catastrophes may change from period to period as a result of several factors, which include but are not limited to, updates to vendor catastrophe models, changes in our own modeling, changes in our underwriting portfolios, changes to our reinsurance purchasing strategy and changes in foreign exchange rates. Several of the aforementioned factors, including the acquisition of Novae and opportunistic purchase of more reinsurance/retrocession protection,our ongoing actions to reduce underwriting volatility, drove the changes to our natural catastrophe PMLs during 2017.2019.



Man-made Catastrophe Risk
Similar toIn line with our management of natural peril catastrophe exposures, we also take a similarsimilarly focused and analytical approach to our management of man-made catastrophes. Man-made catastrophes, which include such risks as train collisions, airplane crashes or terrorism, are harder to model in terms of assumptions regarding intensity and frequency. For these risks we couple the vendor models (where available) with our bespoke modeling and underwriting judgment and expertise. This allows us to take advantage of business opportunities relating to man-made catastrophe exposures particularly where we can measure and limit the risk sufficiently as well as obtain risk-adequate pricing.
As an example of our approach, our assessment of terrorism risk is based on a mixture of qualitative and quantitative data (e.g. for estimating property damage, business interruption, mortality and morbidity subsequent to an attack of a predefined magnitude), which we use to control, limit and manage our aggregate terrorism exposure. We use commercially available vendor modeling and bespoke modeling tools to measure accumulations around potential terrorism accumulation zones on a deterministic and probabilistic basis. We supplement the results of our modeling with underwriting judgment.
Reserving Risk
The estimation of reserves is subject to uncertainty due to the fact that the settlement of claims that have arisen before the balance sheet date is dependent on future events and developments. Unforeseen loss trends resulting from court rulings, changes in the law, medical and long-term care costs, and economic factors such as inflation can have an impact on the ultimate cost to settle our claim liabilities.
We calculate the reserves for losses and claims settlement costsloss expenses ("loss reserves") in accordance with actuarial practice based on substantiated assumptions, methods and assessments. The assumptions are regularly reviewed and updated, and the application of our Group reserving policy and standards of practice ensures a reliable and consistent procedure. Our loss reserving process demands data quality and reliability and requires a quantitative and qualitative review of both our overall reserves and individual large claims. Within a structured control framework, claims information is communicated on a regular basis throughout our organization, including to senior management, to provide an increased awareness regarding the losses that have taken place throughout the insurance markets. The detailed and analytical reserving approach that follows is designed to absorb and understand the latest information on our reported and unreported claims, to recognize the resultant exposure as quickly as possible, and to make appropriate and realistic provisions in our financial statements. We have well established processes for determining carried reserves, which we ensure are applied consistently over time.
Reserving for long-tail lines of business represents a significant component of reserving risk. When loss trends prove to be higher than those underlying our reserving assumptions, the risk is greater because of a stacking-up effect: we carry reserves to cover claims arising from several years of underwriting activity and these reserves are likely to be adversely affected by unfavorable loss trends. We manage and mitigate reserving risk on long-tail business in a variety of ways. First, the long-tail business we write is part of a well-balanced and diversified global portfolio of business. In 2017, our2019, long-tail net premiums written (namely liability and motor business) represented 23%22% of our total net premiums written and 30%long-tail net loss reserves represented 35% of total net loss reserves. We also purchase reinsurance on the liability business to reducemanage our net positions. Secondly, we follow a disciplined underwriting process that utilizes available information, including industry trends.
Another significant component of reserving risk relates to the estimation of losses in the aftermath of a major catastrophe event. For further discussion on this, as well as a descriptionRefer to Item 7 'Management’s Discussion and Analysis of our reserving process, refer to Financial Condition and Results of Operations – Critical Accounting Estimates – ReserveReserves for Losses and Loss Expenses’ under Item 7.Expenses' for further details.
Claims Handling Risk
In accepting risk, we are committing to the payment of claims and therefore these risks must be understood and controlled. We have claims teams located throughout our main business units. Our claim teams include a diverse group of experienced professionals, including claims adjusters and attorneys. We also use approved external service providers, such as independent adjusters and appraisers, surveyors, accountants, investigators and specialist attorneys, as appropriate.
We maintain claims handling guidelines and claims reporting control and escalation procedures in all our claims units. Large claims matters are reviewed during weekly claims meetings. The minutes from each meeting are circulated to our underwriters, senior management and others involved in the reserving process. To maintain communication between underwriting and claims teams, claims personnel regularly report at underwriting meetings and frequently attend client meetings.



We foster a strong culture of review among itsour claims teams. This includes MIAs, whereby senior claims handlers audit a sample of claim files. The process is designed to ensure consistency between the claims units and to develop Group-wide best practices.
When we receive notice of a claim, regardless of size, it is recorded within our underwriting and claims systems. To assist with the reporting of significant claims, we have also developed a standard format and procedure to produce "flash reports" for significant events and potential losses, regardless of whether we have exposure. Our process for flash reporting allows a direct notification to be communicated to underwriters and senior management worldwide. Similarly, for natural peril catastrophes, we have developed a catastrophe database, along with catastrophe coding in certain systems, that allows for the gathering, blending and reporting of loss information as it develops from early modeled results to fully adjusted and paid losses.
Credit Risk
Credit risk represents the risk of incurring financial loss due to the diminished creditworthiness (eroding credit rating and, ultimately, default) of our third partythird-party counterparties. We distinguish between various forms of credit exposure; the risk of issuer default from instruments in which we invest or trade, such as corporate bonds; counterparty exposure in a direct contractual relationship, such as reinsurance; the credit risk related to our receivables, including those from brokers and other intermediaries; and the risk we assume through our insurance contracts, such as our credit and political risk and trade credit and bond lines of business.

Credit Risk Aggregation
We monitor and manage the aggregation of credit risk on a Group-wide basis allowing us to consider exposure management strategies for individual companies, countries, regions, sectors and any other relevant inter-dependencies. Our credit exposures are aggregated based on the origin of risk. Credit risk aggregation is managed through minimizing overlaps in underwriting, financing and investing activities. As part of our credit aggregation framework, we assign aggregate credit limits by country and for any individual counterparty. These limits are based and adjusted on a variety of factors including the prevailing economic environment and the nature of the underlying credit exposures.
Our credit aggregation measurement and reporting process is facilitated by our credit risk exposure database, which contains relevant information on counterparty details and credit risk exposures. The database is accessible by management throughout the Group, thus providing transparency to allow for the implementation of active exposure management strategies. We also license third partythird-party tools to provide credit risk assessments. We monitor all our credit aggregations and, where appropriate, adjust our internal risk limits and/or have taken specific actions to reduce our risk exposures.
Credit Risk Relating to Investing Activities
Within our fixed maturity investment portfolio, which represents approximately $13$12 billion or 51%49% of our total assets, we are exposed to potential losses arising from the diminished creditworthiness of issuers of bonds as well as third partythird-party counterparties such as custodians. We limit such credit risk through diversification, issuer exposure limitationlimits graded by ratings and, with respect to custodians, through contractual and other legal remedies. Excluding U.S. Treasury and Agency securities, we limit our concentration of credit risk to any single corporate issuer to 2% or less of our investment grade fixed maturities portfolio for securities rated A- or above and 1% or less of our investment grade fixed maturities portfolio for securities rated below A-. No more than 1.5% of total cash and invested assets can be invested in any single corporate issuer.
We also have credit risk relating to our cash and cash equivalents. In order to mitigate concentration and operational risks related to cash and cash equivalents, we limit the maximum amount of cash that can be deposited with a single counterparty and additionally limit acceptable counterparties based on current rating, outlook and other relevant factors.
Credit Risk Relating to Reinsurance Recoverable Assets
Within our reinsurance purchasing activities, we are exposed to the credit risk of a reinsurer failing to meet its obligations under our reinsurance contracts. To help mitigate this, all of our reinsurance purchasing is subject to financial security requirements specified by our RSC. The RSC maintains a list of approved reinsurers, reviews credit risk assessments for potential new reinsurers, regularly monitors approved reinsurers with consideration for events which may have a material impact on their creditworthiness, recommends counterparty limits for different types of ceded business and monitors


concentrations of credit risk. This assessment considers a wide range of individual attributes, including a review of the counterparty’s financial strength, industry position and other qualitative factors. Generally, the RSC requires reinsurers who do not meet specified requirements to provide collateral.


We monitor counterparty credit quality and exposures, with special monitoring of those cases that merit close attention.

Credit Risk Relating to Receivables
Our largest credit risk exposure to receivables is from brokers and other intermediaries; the risk arises where they collect premiums from customers to be paid to us or we pay claims to them for onward settlement to customers on our behalf. We have policies and standards in place to manage and monitor credit risk from intermediaries with a focus on day-to-day monitoring of the largest positions.

Credit Risk Relating to our Underwriting Portfolio
In ourthe insurance segment, we provide credit insurance primarily for lenders (financial institutions) seeking to mitigate the risk of non-payment from their borrowers. This product has complemented our more traditional political risk insurance business. For the credit insurance contracts, it is necessary for the buyer of the insurance, most often a bank, to hold an insured asset, most often an underlying loan, in order to claim compensation under the insurance contract. The vast majority of the credit insurance provided is for single-name illiquid risks, primarily in the form of senior secured bank loans that can be individually analyzed and underwritten. As part of this underwriting process, an evaluation of credit-worthinesscreditworthiness and reputation of the obligor is critical and forms the cornerstone of the underwriting process. We generally require that our clients retain a share of each transaction that we insure. A key element to our underwriting analysis is the assessment of recovery in the event of default and, accordingly, the strength of the collateral and the enforceability of rights to the collateral are paramount. We avoid insurance for structured finance products defined by pools of risks and insurance for synthetic products that would expose us to mark-to-market losses. We also seek to avoid terms in our credit insurance contracts which introduce liquidity risk, most notably, in the form of a collateralization requirement upon a ratings downgrade. We also provide protection against sovereign default or sovereign actions that result in impairment of cross-border investments for banks and corporations. Our contracts generally include conditions precedent to our liability relating to the enforceability of the insured transaction and restricting amendments to the transaction documentation, obligations on the insured to prevent and minimize losses, subrogation rights (including rights to have the insured asset transferred to us) and waiting periods. Under most of our policies, a loss payment is made in the event the debtor failed to pay our client when payment is due subject to a waiting period of up to 180 days.
In ourthe reinsurance segment, we provide reinsurance of credit and bond insurers exposed to the risks of financial loss arising from non-payment of trade receivables covered by a policy (credit insurance) or non-performance (bonding). Our credit insurance exposures are concentrated primarily within Western Europeandeveloped economies, while our surety bond exposures are concentrated primarily within Latin American and Western Europeandeveloped economies. We also provide coverage to the mortgage industry through insurance and reinsurance of mortgage insurance companies and U.S. government sponsored entity credit risk sharing transactions. We focus on credit risk transfer from Federal Home Loan Mortgage Corporation and Federal National Mortgage Association, in the single-family, fixed rate, conforming mortgage space. We provide this cover on a proportional and non-proportional basis globally through AXIS Re U.S., AXIS Specialty Bermuda and AXIS Managing Agency Ltd. Our exposure to mortgage risk is monitored and managed through robust underwriting within defined parameters for mortgage credit quality and concentration, continuous monitoring of the housing market, as well as limits on our PML resulting from a severe economic downturn in the housing market.
Market Risk
Market risk is the risk that our financial instruments may be negatively impacted by movements in financial market prices or rates such as equity prices, interest rates, credit spreads and foreign exchange rates. Fluctuations in market rates primarily affect our investment portfolio.
Through asset and liability management, we aim to ensure that market risks influence the economic value of our investments and that of our loss reserves and other liabilities in the same way, thus mitigating the effect of market fluctuations. For example, we reflect important features of our liabilities, such as maturity patterns and currency structures, on the assets side of the balance sheet by acquiring investments with similar characteristics.



We supplement our asset-liability management with various internal policies and limits. As part of our strategic asset allocation process, different asset strategies are simulated and stressed in order to evaluate the ‘optimal’ portfolio (given return objectives and risk constraints) at both the group and operating entity level.. In our investment department, we centralize the management of asset classes to control aggregation of risk and provide a consistent approach to constructing portfolios as well as the selection process of external asset managers. We have limits on the concentration of investments by single issuers and certain asset classes, and we limit the level of illiquid investments (see(refer to 'Liquidity Risk' below). Further, our investment guidelines do not permit the use of leverage in any of our fixed maturity portfolios.
We stress test our investment portfolios using historical and hypothetical scenarios to analyze the impact of unusual market conditions and to ensure potential investment losses remain within our risk appetite. At an annual aggregated level, we manage the total risk exposure to our investment portfolio so that the ‘total return’ investment loss in any one year is unlikely to exceed a defined percentage of our common equity at a defined return period.
We mitigate foreign currency risk by seeking to match our estimated (re)insurance and reinsurance liabilities payable in foreign currencies with assets, including cash and investments that are also denominated in such currencies. Where necessary, we use derivative financial instruments for economic hedging purposes. For example, in certain circumstances, we use forward contracts and currency options, to economically hedge portions of our un-matched foreign currency exposures.
Operational Risk
Operational risk represents the risk of financial loss as a result of inadequate processes, system failures, human error or external events.
Group Risk is responsible for coordinating and overseeing a Group-wide framework for operational risk management. As part of this, we maintain an operational loss-event database which helps us better monitor and analyze potential operational risk, identify any trends, and, where necessary, put in place improvement actions to avoid occurrence or recurrence of operational loss events.
We manage transaction type operational risks through the application of process controls throughout our business. In testing these controls, we supplement the work of our internal audit team, with regular underwriting and claim MIAs (as discussed above).
We have specific processes and systems in place to focus on high priority operational matters, such as information security, managing business continuity, and third partythird-party vendor risk:
Major failures and disasters which could cause a severe disruption to working environments, facilities and personnel, represent a significant operational risk to us. Our Business Continuity Management framework strives to protect critical business functions from these effects to enable us to carry out our core tasks in time and at the quality required. During 2017,2019, we continued to review our Business Continuity Planning procedures through cyclical planned tests.

We have developed a number of Information Technology ("IT") platforms, applications and security controls to support our business activities worldwide. Dedicated security standards are in place for our IT systems to ensure the proper use, availability and protection of our information assets.

Our use of third partythird-party vendors exposes us to a number of increased operational risks, including the risk of security breaches, fraud, non-compliance with laws and regulations or internal guidelines and inadequate service. We manage material third partythird-party vendor risk, by, among other things, performing a thorough risk assessment on potential large vendors, reviewing a vendor’s financial stability, ability to provide ongoing service and business continuity planning.

Liquidity Risk
Liquidity risk is the risk that we may not have sufficient financial resources to meet our obligations when they fall due or would have to incur excessive costs to do so. As a (re)an insurer and reinsurer, our core business generates liquidity primarily through premium,premiums, investment income and the maturity/sale of investments. Our exposure to liquidity risk stems mainly from the need to cover potential extreme loss events and regulatory constraints that limit the flow of funds within the Group. To manage these risks, we have a range of liquidity policies and measures in place:
 



We maintain cash and cash equivalents and high quality, liquid investment portfolios to meet expected outflows, as well as those that could result from a range of potential stress events. We place internal limits on the maximum percentage of cash and investments which may be in an illiquid form as well as aon the minimum percentage of our asset portfolio which may be invested in unrestricted cash and liquid investment portfolio to mature within a defined timeframe.

grade fixed income securities.
We maintain committed borrowing facilities, as well as access to diverse funding sources to cover contingencies. Funding sources include asset sales, external debt issuances and lines of credit.
Capital Management
Our capital management strategy is to maximize long-term shareholder value by, among other things, optimizing capital allocation and minimizing our cost of capital. We manage our capital in accordance with our Target Capital Range ("TCR") concept. The TCR defines the preferred level of capital needed to absorb shock losses and still satisfy our minimum solvency targets in relation to key capital benchmarks including our "own view" of risk from our internal capital model and regulatory and rating agency capital requirements:
Internal risk capital - We use our internal capital model to assess the capital consumption of our business, measuring and monitoring the potential aggregation of risk at extreme return periods.
Regulatory capital requirements - In each country in which we operate, the local regulator specifies the minimum amount and type of capital that each of the regulated entities must hold in support of their liabilities and business plans. We target to hold, in addition to the minimum capital required to comply with the solvency requirements, an adequate buffer to ensure that each of our operating entities meets its local capital requirements. For further information refer to Item 8, Note 21 of the Consolidated Financial Statements, 'Statutory Financial Information' section of this report.
Rating agency capital requirements - Rating agencies apply their own models to evaluate the relationship between the required risk capital of a company and its available capital resources. The assessment of capital adequacy is usually an integral part of the rating agency process. Meeting rating agency capital requirements and maintaining strong credit ratings are strategic business objectives of the Company. For further information on our financial strength refer to Item 7, 'Liquidity and Capital Resources' section of this report.
Regulatory capital requirements - In each country in which we operate, the local regulator specifies the minimum amount and type of capital that each of the regulated entities must hold in support of their liabilities and business plans. We target to hold, in addition to the minimum capital required to comply with the solvency requirements, an adequate buffer to ensure that each of our operating entities meets its local capital requirements. Refer to Item 8, Note 21 to the Consolidated Financial Statements, 'Statutory Financial Information' for further details.
Rating agency capital requirements - Rating agencies apply their own models to evaluate the relationship between the required risk capital of a company and its available capital resources. The assessment of capital adequacy is usually an integral part of the rating agency process. Meeting rating agency capital requirements and maintaining strong credit ratings are strategic business objectives of the Company. Refer to Item 7 'Management’s Discussion and Analysis of Financial Condition and Results of Operations –Liquidity and Capital Resources' for further details.
The TCR identifies the point at which managementsmanagement needs to consider raising capital, amending our business plan or executing capital management activities well before capital approaches the minimum requirements ("early warning indicator"). This allows us to take appropriate measures to ensure the continued strength and appropriateness of our capital and solvency positions, and also enables us to take advantage of opportunities as they arise. Such measures are performed as and when required and include traditional capital management tools (e.g. dividends, share buy-backs, issuance of shares or debt) or through changes to our risk exposure (e.g. recalibration of our investment portfolio or changes to our reinsurance purchasing strategy).
The TCR also considers an amount of capital beyond which capital could be considered "excess". Where we do not find sufficiently attractive opportunities and returns for our excess capital, we may return capital back to our shareholders through share repurchases andand/or dividends. In doing so, we seek to maintain an appropriate balance between higher returns for our shareholders and the security provided by a sound capital position.





REGULATION

General
The business of (re)insurance and reinsurance is regulated in most countries, although the degree and type of regulation varies significantly from one jurisdiction to another. In addition, some jurisdictions are currently evaluating changes to their regulation and we are monitoring these potential developments. To the extent we are aware of impending changes in regulation, designated project teams prepare us to comply on a timely basis with such anticipated changes. The following describes the current material regulations under which the Company operates.
Bermuda
Our Bermuda insurance operating subsidiary, AXIS Specialty Bermuda, is a Class 4 general business insurer subject to the Insurance Act 1978 of Bermuda and related regulations, as amended (the "Insurance Act"). The Insurance Act provides that no person may carry on any insurance or reinsurance business in or from within Bermuda unless registered as an insurer by the Bermuda Monetary Authority (the "BMA") under the Insurance Act. The Insurance Act imposes upon Bermuda insurance companies solvency and liquidity standards and auditing and reporting requirements, and grants the BMA powers to supervise, investigate, require information and demand the production of documents and intervene in the affairs of insurance companies. Significant requirements pertaining to Class 4 insurers include the appointment of an independent auditor, the appointment of a loss reserve specialist, the appointment of a principal representative in Bermuda, the filing of annual Statutory Financial Returns, the filing of annual GAAP financial statements, the filing of an annual capital and solvency return, compliance with minimum and enhanced capital requirements, compliance with certain restrictions on reductions of capital and the payment of dividends and distributions, compliance with group solvency and supervision rules, if applicable, and compliance with the Insurance Code of Conduct. On July 30, 2018, the Insurance Amendment (No. 2) Act 2018 amended the Insurance Act to provide for the prior payment of policyholders' liabilities ahead of general unsecured creditors in the event of the liquidation or winding up of an insurer. Effective January 1, 2019, this amendment applies to general business insurers and provides among other things that, subject to certain statutorily preferred debts, the insurance debts of an insurer must be paid in priority to all other unsecured debts of the insurer. Insurance debt is defined as a debt to which an insurer is or may become liable pursuant to an insurance contract excluding debts owed to an insurer under an insurance contract where the insurer is the person insured.
Effective January 1, 2016, the BMA was granted full "equivalence" under Solvency II (as more fully described below under "Ireland") for Bermuda’s commercial insurance sector, including Class 4 insurers.
The BMA acts as group supervisor of AXIS Capital and has designated AXIS Specialty Bermuda as the ‘designated insurer’ of the AXIS Capital insurance companies.Group. In accordance with the group supervision and insurance group solvency rules, AXIS Capital is required to prepare and submit annual audited group GAAP financial statements, an annual group Statutory Financial Return, an annual group Capital and Solvency Return and quarterly group unaudited GAAP financial statements, and to appoint both a group actuary and a group auditor.

U.S. Insurance Holding Company Regulation of AXIS Capital’s Insurance Subsidiaries
As members of an insurance holding company system, each of AXIS Insurance Company,Co., AXIS Reinsurance Company,Re U.S., AXIS Specialty Insurance CompanyU.S. and AXIS Surplus, Insurance Company, collectively AXIS Capital’s U.S. insurance subsidiaries ("U.S. Insurance Subsidiaries") are subject to the insurance holding company system laws and regulations of the states in which they do business. These laws generally require each of the U.S. Insurance Subsidiaries to register with its respective domestic state insurance department and to furnish financial and other information which may materially affect the operations, management or financial condition within the holding company system. All transactions within a holding company system that involve an insurance company must be fair and equitable. Notice to the insurance departments is required prior to the consummation of transactions affecting the ownership or control of an insurer and of certain material transactions between an insurer and an entity in its holding company system, and certain transactions may not be consummated without the department’s prior approval.
State Insurance Regulation
AXIS Reinsurance CompanyRe U.S. is licensed to transact insurance and reinsurance in all 50 ofthroughout the U.S., the District of Columbia and in Puerto Rico. AXIS Reinsurance CompanyRe U.S. is also authorized to transact insurance and reinsurance throughout Canada through its Canadian branch and has reinsurance permissions in Argentina, Brazil, China, Columbia, Ecuador, Guam, Guatemala, Honduras, Panama, India and Mexico. AXIS Insurance CompanyCo. is licensed to transact insurance and reinsurance in all 50 ofthroughout the U.S. and in the District of Columbia. AXIS Specialty Insurance CompanyU.S. is licensed to transact insurance and reinsurance throughout the U.S., except California, Iowa, Maine, New Mexico, New York and Wyoming. AXIS Surplus Insurance Company is eligible to write insurance on a surplus lines basis in all 50 ofthroughout the U.S., the District of Columbia,Puerto Rico and the U.S. Virgin Islands and Puerto Rico.Islands.
Our U.S. Insurance Subsidiaries also are subject to regulation and supervision by their respective states of domicile and by other jurisdictions in which they do business. The regulations generally are derived from statutes that delegate regulatory and supervisory powers to an insurance official. The regulatory framework varies from state to state, but generally relates to approval of policy forms and rates, the standards of solvency that must be met and maintained, including risk-based capital standards, material transactions between an insurer and its affiliates, the licensing of insurers, agents and brokers, restrictions on insurance policy terminations, the nature of and limitations on the amount of certain investments, limitations on the net amount of insurance of a single risk compared to the insurer’s surplus, deposits of securities for the benefit of policyholders, methods of accounting, periodic examinations of the financial condition and market conduct of insurance companies, the form and content of reports of financial condition required to be filed, reserves for unearned premiums, losses, expenses and other obligations.
Our U.S. Insurance Subsidiaries are required to file detailed quarterly statutory financial statements with state insurance regulators in each of the states in which they conduct business. In addition, the U.S. Insurance Subsidiaries’ operations and accounts are subject to financial condition and market conduct examination at regular intervals by state regulators.
Regulators and rating agencies use statutory surplus as a measure to assess our U.S. Insurance Subsidiaries’ ability to support business operations and pay dividends. Our U.S. Insurance Subsidiaries are subject to various state statutory and regulatory


restrictions that limit the amount of dividends that may be paid from earned surplus without prior approval from regulatory authorities. These restrictions differ by state, but generally are based on calculations using statutory surplus, statutory net


income and investment income. In addition, many state regulators use the National Association of Insurance Commissioners promulgated risk-based capital requirements as a means of identifying insurance companies which may be under-capitalized.
Although the insurance industry generally is not directly regulated by the federal government, federal legislation and initiatives can affect the industry and our business. Certain sections of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 ("Dodd-Frank") pertain to the regulation and business of insurance. Specifically, the Federal Insurance Office was created ("FIO") has limited authority and serves to collect information and report on the business of insurance to Congress. In addition, Dodd-Frank contains the Non-admitted and Reinsurance Reform Act of 2010 ("NRRA"). NRRA attempts to coordinate the payment of surplus lines taxes, simplify the granting of alien insurers to become surplus lines authorized and coordinates the credit for certain reinsurance. Various sections of Dodd-Frank become effective over time and regulations have yet to be drafted for certain provisions. AXISThe Company does not anticipate that Dodd-Frank will have any material effect on its operations or financial condition this year, but will continue to monitor its implementation.
Ternian Insurance Group LLC, a leading provider of voluntary, limited benefit, affordable health plans and other employee benefits coverage for hourly and part-time workers and their families, is an authorized insurance producer in all 50 of the U.S. except Hawaii. As a resident insurance producer in Arizona, Ternian Insurance Group LLC is subject to regulation and supervision by the Arizona Department of Insurance and is also subject to the regulation and supervision of the other states in which Ternian transacts business.
AXIS Specialty Underwriters, Inc., a Florida licensed reinsurance intermediary, is subject to regulation and supervision by the Florida Department of Financial Services. AXIS Specialty Underwriters, Inc. operates as the Latin American and Caribbean regional coverholder for AXIS Syndicate 1686 providing facultative reinsurance coverage to the Latin American and Caribbean market with a focus on energy and property business.
U.S. Authorizations of our Non-U.S. Insurance Subsidiaries
The insurance laws of each state of the U.S. regulate or prohibit the sale of (re)insurance and reinsurance within their jurisdictions by (re)insurers and reinsurers that are not admitted to do business within such jurisdictions, or conduct business pursuant to exemptions. AXIS Specialty Europe is eligible to write surplus lines business in all 50 ofthroughout the U.S., the District of Columbia and in Puerto Rico. AXIS Managing Agency LimitedLtd. is eligible to use Lloyd's of London licenses to (i) write surplus lines business in all 50 ofthroughout the U.S., in the District of Columbia and in all U.S. territories, (ii) to write insurance business, except life insurance business, in the states of Illinois, Kentucky and in the U.S. Virgin Islands and (iii) to write non-life reinsurance business in all 50 ofthroughout the U.S., the District of Columbia and in all U.S. territories, except for accident and health reinsurance in New York.
In addition to the regulatory requirements imposed by the jurisdictions in which they are licensed, reinsurers’ business operations are affected by regulatory requirements in various states of the U.S. governing "credit for reinsurance" that are imposed on their ceding companies. In general, a ceding company obtaining reinsurance from a reinsurer that is licensed, accredited or approved by the jurisdiction or state in which the ceding company files statutory financial statements is permitted to reflect in its statutory financial statements a credit in an aggregate amount equal to the ceding company’s liability for unearned premiums (which are that portion of premiums written which applies to the unexpired portion of the policy period), loss reserves and loss expense reserves ceded to the reinsurer. The great majority of states, however, permit a credit to statutory surplus resulting from reinsurance obtained from a non-licensed or non-accredited reinsurer to be recognized to the extent that the reinsurer provides a letter of credit, trust fund or other acceptable security arrangement. A few states do not allow credit for reinsurance ceded to non-licensed reinsurers except in certain limited circumstances and others impose additional requirements that make it difficult to become accredited.

ITEM 1A.
RISK FACTORS

You should carefully considerInsurance Risk
Insurance risk is the following risksinherent uncertainty as to the occurrence, amount and alltiming of insurance and reinsurance liabilities transferred to us through the other information set forth in this report, including our consolidated financial statements and the notes thereto:underwriting process.
The (re)insuranceinsurance/reinsurance business is historically cyclical, and we expect to experience periods with excess underwriting capacity and unfavorable premium rates.
The (re)insuranceinsurance/reinsurance business historically has been a cyclical industry characterized by periods of intense price competition due to excessiveexcess underwriting capacity as well as periods when shortages of capacity permitted favorable premium levels. An increase in premium rates is often offset by an increasing supply of (re)insurance and reinsurance capacity, via capital provided by new entrants, new capital market instruments and structures and/or the commitment of additional capital by existing (re)insurers and reinsurers, which may cause prices to decrease. Any of these factors could lead to a significant reduction in premium rates, less favorable policy terms and fewer submissions for our underwriting services. In addition to these considerations, changes in the frequency and severity of losses suffered by insureds and insurers may affect the cycles of the (re)insuranceinsurance/reinsurance business significantly.
Competition and consolidation in the (re)insurance industry could reduce our growth and profitability.
The (re)insurance industry is highly competitive. We compete on an international and regional basis with major U.S., Bermuda, European and other international (re)insurers and underwriting syndicates, including Lloyd's, some of which have greater financial, marketing and management resources than we do. We also compete with new companies that continue to be formed to enter the (re)insurance markets. In addition, capital market participants have created alternative products that are intended to compete with reinsurance products. New and alternative capital inflows in the (re)insurance industry and the retention by cedants of more business have caused an excess supply of (re)insurance capital. There has been a large amount of merger and acquisition activity in the (re)insurance sector in recent years and we may experience increased competition as a result of that consolidation with consolidated entities having enhanced market power. In addition, there is a risk of continued consolidation in the sector which could result in competition from larger competitors. Increased competition could result in fewer submissions, lower premium rates, less favorable policy terms and conditions and greater costs of customer acquisition and retention. In addition, if industry pricing does not meet our hurdle rate, we may reduce our future underwriting activities. These factors could have a material adverse effect on our growth and profitability.

Global economic conditions could materially and adversely affect our business, results of operations and financial condition.

Worldwide financial markets can be volatile. In 2008 and 2009, for example, there was volatility and disruption including, among other things, dislocation in the mortgage and asset-backed securities markets, deleveraging and decreased liquidity generally, widening of credit spreads, bankruptcies and government intervention in a number of large financial institutions. These events resulted in extraordinary responses by governments worldwide, including the enactment of the Emergency Economic Stabilization Act of 2008 and the U.S. Recovery and Reinvestment Act in 2009 and Dodd Frank. Uncertainty and market turmoil has affected (among other aspects of our business), and may in the future affect, the demand for and claims made under our products, the ability of customers, counterparties and others to establish or maintain their relationships with us, our ability to access and efficiently use internal and external capital resources and our investment performance and portfolio.

In addition, steps taken by governments to stabilize financial markets and improve economic conditions may be ineffective and actual or anticipated efforts to continue to unwind some of such steps could disrupt financial markets and/or could adversely impact the value of our investment portfolio. While inflation has recently been moderate and that trend may continue, it is possible that expansionary monetary policies, recent changes to the U.S. tax law, improving economic conditions, higher commodity prices and tighter labor markets could lead to an inflationary environment.

The current U.S. administration has called for comprehensive regulatory reform and questioned certain existing legislation, including the Affordable Care Act and Dodd Frank. It is uncertain how any such reform could affect our business. Governmental action and legislation resulting from the U.S. administration, including the recently enacted U.S. Tax Reform as well as political debate, conflicts and compromises related to such actions, may impact the financial markets and consumer


confidence and spending or adversely impact the U.S. economy. See "Changes in U.S. federal income tax law and other tax laws, including changes resulting from the recommendations of the Organization for Economic Cooperation and Development ("OECD"), could materially adversely affect us" below.

Given the ongoing global economic uncertainties, evolving market conditions may continue to affect our results of operations, financial position and capital resources. In the event that there is additional deterioration or volatility in financial markets or general economic conditions, our results of operations, financial position, capital resources and competitive landscape could be materially and adversely affected.
Our results of operations, and financial condition, or liquidity could be materially adversely affected by the occurrence of natural and man-made disasters.

disasters, as well as outbreaks of pandemic or contagious diseases.
We have substantial exposure to unexpected losses resulting from natural disasters, man-made catastrophes and other catastrophe events. Catastrophes can be caused by various events, including hurricanes, typhoons, earthquakes, tsunamis, hailstorms, floods, explosions, severe winter weather, fires, drought, and other natural disasters and outbreaks of pandemic or man-made disasters.contagious diseases. Catastrophes can also be man-made, such as terrorist attacks and other intentionally destructive acts, including those involving nuclear, biological, chemical or radiological events, cyber-attacks, explosions and infrastructure failures. The incidence and severity of catastrophes are inherently unpredictable and our losses from catastrophes could be substantial.

Increases in the values and concentrations of insured property, particularly along coastal regions, andas well as increases in the cost of construction materials required to rebuild affected properties, may increase the impact of these occurrences on uscatastrophe events in the future. Changes in global climate conditions may further increase the frequency and severity of catastrophe activity and losses in the future. Similarly, changes in global political and economic conditions may increase both the frequency and severity of man-made catastrophe events in the future. Examples of the impact of catastrophe events include ourthe recognition of the net losses and loss expenses of:

$336 million, in the aggregate, primarily related to Japanese Typhoons Hagibis, Faxai and Tapah, Hurricane Dorian, and the Australia Wildfires in 2019;
$430 million, in the aggregate, primarily related to Hurricanes Michael and Florence, California Wildfires, and Typhoon Jebi in 2018; and
$835 million, in the aggregate, primarily related to U.S. weather-related events, Hurricanes Harvey, Irma and Maria, Mexico earthquakes and the California wildfires in 2017;
$204 million, in aggregate, relating to U.S. weather-related events, Hurricane Matthew, Fort McMurray wildfires, the Japanese, Ecuadorian and South Island earthquakes, North Calgary hailstorm and European floods in 2016;

$331 million in relation to Storm Sandy in 2012;
$789 million, in aggregate, in relation to the earthquakes near Christchurch, New Zealand, the Japanese earthquake and tsunami, Australian weather events and the Thai floods in 2011; and
$256 million, in aggregate, in relation to the Chilean and September New Zealand earthquakes in 2010.2017.
These events materially reduced our net income in the years noted above. Although we attempt to manage our exposure to such events through the use of underwriting controls and the purchase of third-party reinsurance, catastrophe events are inherently unpredictable and the actual nature of such events when they occur could be more frequent or severe than contemplated in our pricing and risk management expectations. As a result, the occurrence of one or more catastrophe events could have a material adverse effect on our results of operations, financial condition, or financial condition.liquidity.
With regard to cyber-attacks, this is an area whereCyber events are man-made perils and as such the threat landscape is evolving,dynamic and thereevolving. There is a risk that increases in the frequency and severity of cyber-attacks onlosses to our clients from cyber events could adversely affect our results of operations or financial condition and operating results. Thiscondition. The losses incurred from this risk isare also dependent on our clients'clients’ cybersecurity practices and defenses and the interaction of our issuance of policy terms which respond towordings with the evolving threat landscape. In addition, our exposure to cyber-attackscyber events potentially includes exposure to silent cyber risks,through ‘non-affirmative’ coverages, meaning risks and potential losses associated with policies where cyber risk is not specificallyexplicitly included noror excluded in the policies. Evenpolicy wording. As this is a relatively new peril, even in cases

Global climate change may have a material adverse effect on our results of operations, and financial condition, if weor liquidity.
We are not ablepotentially exposed to adequately assessdifferent aspects of climate risk, specifically, physical, liability and reserve for thetransition risks, as a result of climate change.
Physical risks describe weather-related events and longer-term shifts in climate, and emanate primarily from underwriting of property insurance and reinsurance. Climate change may expose us to an increased frequency andand/or severity of catastrophes resulting from these environmental factors.
The frequency and severity of natural catastrophe activity, including hurricanes, tsunamis, tornadoes, floods and droughts, has been greater in recent years. Atmospheric concentrations of carbon dioxide and other greenhouse gases have increased dramatically since the industrial revolutionweather-related losses, and there is debatea risk that our pricing of these perils or our management of the associated aggregations does not or will not appropriately allow for changes in climate. Over the longer term, climate change may have an impact on the economic viability of certain lines of business, if suitable adjustments in price and coverage cannot be achieved.
We may also be exposed to liability risks. Liability risks relate to losses or damages suffered by our insureds from physical or transition risks, such as losses stemming from climate-related litigation in liability lines. These risks could arise from management and boards not fully considering or responding to whetherthe impacts of climate change, or not appropriately disclosing current and future risks.
There is additionally a risk that certain elements of our business cease to be viable as a result of climate change ‘transition’ risks, which relate to losses driven by changes in technology, governments and regulators putting into place measures to encourage and support this has causedtransition, and society as a gradual increase in global average temperatures. Increasing global average temperatures may continuewhole adapting to a lower-carbon economy. Recognizing the importance of this transition, effective 2020 AXIS Capital will cease underwriting risks for (and investing in the future and could impactsecurities of) companies whose primary activity relates to thermal coal mining or power generation, or tar sands extraction. There remains a risk that our financial condition or operating performance may be impacted by changes in our business in the long-term.
We attempt to mitigate the risk of financial exposuremodel arising from climate change throughtransition, and by the performance of strategies we put in place to manage this transition.
Furthermore, we may be exposed to losses in the value of our underwriting risk management practices. This includes sensitivity to geographic concentrationsinvestments arising from the physical and transition impacts of risks,climate change, including 'stranded assets', on the purchase of protective reinsurancecompanies and selective underwriting criteriasecurities in which can include, but is not limited to, higher premiums and deductibles and more specifically excluded policy risks. However, due to lack of scientific certainty about the causes of increased frequency and severity of catastrophes and the lack of adequate predictive tools, a continuation and worsening of recent trends may have a material impact on our results of operations or financial condition.we invest.
We could face unanticipated losses from war, terrorism, political unrest, and geopolitical uncertainty and these or other unanticipated losses could have a material adverse effect on our financial condition, results of operations, and/financial condition, or liquidity.
We have substantial exposure to unexpected losses resulting from war, acts of terrorism, political unrest and geopolitical instability in many regions of the world. In certain instances, we specifically (re)insure and reinsure risks resulting from acts of terrorism. Even in cases where we attempt to exclude losses from terrorism and certain other similar risks from some coverages written by us, there can be no assurance that a court or arbitration panel will interpret policy language or otherwise issue a ruling favorable to us. Accordingly, we can offer no assurance that our reserves for losses and loss expenses ("loss reserves") will be adequate to cover losses should they materialize.
We have limited terrorism coverage in our own reinsurance program for our exposure to catastrophe losses related to acts of terrorism. Furthermore, althoughOn December 20, 2019, the President of the United States signed the Terrorism Risk Insurance ExtensionProgram Reauthorization Act of 20052019 ("TRIEA"TRIP"), extending the program through December 31, 2027. Although TRIP provides benefits in the event of certain acts of terrorism, those benefits are subject to a deductible and to other limitations. Under TRIEA,TRIP, once our losses attributable to certain acts of terrorism exceed 20% of our direct commercial property and liability insurance premiums for the preceding calendar year, the federal government will reimburse usinsurers for 85%80% of such losses in excess of this deductible. Notably, TRIEATRIP does not provide coverage for reinsurance losses. Given the unpredictable frequency and severity of terrorism losses, as well as the limited terrorism coverage in our own reinsurance program, future losses from acts of terrorism could materially and adversely affect our results of operations, financial condition, and/or liquidity in future periods. TRIEA expired at the end of 2014 but was reauthorized, with some adjustments to its provisions, in January 2015 for six years through December 31, 2020. Over the six-year life of the reauthorized program, the federal government reimbursement percentage will drop from 85% to 80%.
Our credit and political risk insurance line of business protects insureds with interests in foreign jurisdictions in the event that governmental action prevents them from exercising their contractual rights, and may also protect their assets against physical damage perils. The insurance provided may include cover for losslosses arising from expropriation, forced abandonment, license cancellation, trade embargo, contract frustration, non-payment, war on land or political violence (including terrorism, revolution, insurrection and civil unrest).

Our credit and political risk line of business also provides non-payment coverage on specific loan obligations. We insure sovereign non-payment and corporate non-payment as a result of commercial as well as political risk events. The vast majority of the corporate non-payment credit insurance provided is for single-named illiquid risks, primarily in the form of senior bank loans that can be individually analyzed and underwritten. We avoid insurance for structured finance products


defined by pools of risks and insurance for synthetic products that would expose us to mark-to-market losses. We also avoid terms in our credit insurance contracts which introduce liquidity risk, most notably, in the form of a collateralization requirement upon a ratings downgrade. We also attempt to manage our exposure, by among other things, setting credit limits by country, region, industry and individual counterparty, and regularly reviewing our aggregate exposures. However, due to globalization, political instability in one region can spread to other regions. Geopolitical uncertainty regarding a variety of domestic and international matters, such as the U.S. political and regulatory environment, the potential for default by one or


more European sovereign debt issuers and Brexit (as defined below) could have a material adverse effect on our results of operations, or financial condition.
A downgrade in our financial strength or credit ratings by one or more rating agencies could materially and negatively impact our business, financial condition, results of operations and/or liquidity.
Our ability to underwrite business is dependent upon the quality of our claims paying and financial strength ratings as evaluated by independent rating agencies. A downgrade, withdrawal or negative watch/outlook by any of these institutions could cause our competitive position in the (re)insurance industry to suffer and make it more difficult for us to market our products. If we experience a credit rating downgrade, withdrawal or negative watch/outlook in the future, we could incur higher borrowing costs and may have more limited means to access capital. A downgrade, withdrawal or negative watch/outlook could also result in a substantial loss of business for us, as ceding companies and brokers that place such business may move to other (re)insurers with higher ratings. We would also be required to post collateral under the terms of certain of our policies of reinsurance.

If actual claims exceed our loss reserves, our financial results could be adversely affected.
While we believe that our loss reserves at December 31, 2017 are adequate, new information, events or circumstances, unknown at the original valuation date, may lead to future developments in our ultimate losses being significantly greater or less than the reserves currently provided. The actual final cost of settling claims outstanding at December 31, 2017 as well as claims expected to arise from the unexpired period of risk is uncertain. There are many other factors that would cause our reserves to increase or decrease, which include, but are not limited to, changes in claim severity, changes in the expected level of reported claims, judicial action changing the scope and/or liability of coverage, changes in the legislative, regulatory, social and economic environment and unexpected changes in loss inflation.

Our relatively limited operating history, which includes periods of rapid growth, means that our loss reserve estimates, particularly on the longer tailed classes of business, may place more reliance on industry benchmarks than might be the case for companies with longer operating histories; as a result, the potential for volatility in our estimated loss reserves may be more pronounced than for more established companies. When establishing our single point best estimate of loss reserves at December 31, 2017, our management considered actuarial estimates and applied informed judgment regarding qualitative factors that may not be fully captured in actuarial estimates. Such factors included, but were not limited to: the timing of the emergence of claims, volume and complexity of claims, social and judicial trends, potential severity of individual claims and the extent of internal historical loss data versus industry information.
Changes to our previous estimate of prior year loss reserves can adversely impact the reported calendar year underwriting results if reserves prove to be insufficient or favorably impact our reported results if loss reserves prove to be higher than actual claim payments. If our net income is insufficient to absorb a required increase in our loss reserves, we would incur an operating loss and could incur a reduction of our capital.liquidity.
The effects of emerging claim and coverage issues on our business are uncertain.
As industry practices and legal, judicial, social, political, technological and other environmental conditions change, unexpected issues related to claims and coverage may emerge. These issues may adversely affect our business by either extending coverage beyond our underwriting intent or by increasing the frequency and/or severity of claims. For example, the last global financial crisis resulted in a higher level of claim activity on professional lines (re)insurance and reinsurance business. In some instances, the effects of these changes may not become apparent until some timesometime after we have issued the impacted insurance or reinsurance contracts that are affected by the changes.contracts. In addition, our actual losses may vary materially from ourthe current estimate of the losslosses based on a number of factors (see ‘(refer to "If actual claims exceed our loss reserves, our financial results could be adversely affected’ above)affected" below). As a result, the full extent of liability under an insurance or reinsurance contract may not be known for many years after suchthe contract is issued and a loss occurs.

If actual claims exceed loss reserves, our financial results could be adversely affected.
Our investment and derivative instrument portfoliosWhile we believe that loss reserves at December 31, 2019 are exposedadequate, new information, events or circumstances, unknown at the original valuation date, may lead to significant capital markets risk related to changesfuture developments in interest rates, credit spreads and equity pricesultimate losses being significantly greater or less than the loss reserves currently provided. The actual final cost of settling claims outstanding at December 31, 2019, as well as other risks, which may adversely affect our resultsclaims expected to arise from the unexpired period of operations, financial condition or cash flows.


The performance of our cash and investments portfolio has a significant impact on our financial results. A failure to successfully execute our investment strategy could have a significant impact on our results of operations or financial condition.
Our investment portfoliorisk is subject to a variety of market risks, including risks relating to general economic conditions, interest rate fluctuations, equity price risk, foreign currency movements, pre-payment or reinvestment risk, liquidity risk and credit risk. Although we attempt to manage market risks through, among other things, stressing diversification and conservation of principal and liquidity in our investment guidelines, it is possible that, in periods of economic weakness or periods of turmoil in capital markets, we may experience significant losses in our portfolio.
Our fixed maturities, which represent 85% of our total investments and 78% of total cash and investments at December 31, 2017, may be adversely impacted by changes in interest rates. Increases in interest rates could cause the fair value of our investment portfolio to decrease, resulting in a lower book value (refer to Item 7A 'Quantitative and Qualitative Disclosure About Market Risk' for a related sensitivity analysis) and capital resources.
In addition, a lower interest rate environment can result in reductions in our investment yield as new funds and proceeds from sales and maturities of fixed income securitiesuncertain. There are re-invested at lower rates. This reduces our overall future profitability. Interest rates are highly sensitive to many factors, including governmental and central bank monetary policies, inflation, domestic and international economic and political conditions and other factors beyond our control.
Our portfolios of "other investments" and equity securities expose usthat would cause loss reserves to market price variability, driven by a number of factors outside our control including, but not limited to, global equity market performance.
Given our reliance on external investment managers, we are also exposed to operational risks,increase or decrease, which may include, but are not limited to a failure to follow our investment guidelines, technologicalchanges in claim severity, changes in the expected level of reported claims, judicial action changing the scope and/or liability of coverage, changes in the legislative, regulatory, social and staffing deficiencieseconomic environment, and inadequate disaster recovery plans.unexpected changes in loss inflation.
Our derivative instrument counterpartiesoperating history, which includes periods of rapid growth, means that loss reserve estimates, particularly on the longer tailed classes of business, may defaultplace more reliance on amounts owed to us due to bankruptcy, insolvency, lack of liquidity, adverse economic conditions, operational failure, fraud or other reasons. Even if we are entitled to collateralindustry benchmarks than might be the case for companies with longer operating histories; as a result, the potential for volatility in circumstances of default, such collateralestimated loss reserves may be illiquid or proceeds from such collateral when liquidatedmore pronounced than for more established companies.

Such factors included, but were not limited to, recover the full amounttiming of the obligation.emergence of claims, volume and complexity of claims, social and judicial trends, potential severity of individual claims, and the extent of internal historical loss data versus industry information.
Changes to previous estimates of prior year loss reserves can adversely impact the reported calendar year underwriting results if loss reserves prove to be insufficient or can favorably impact reported results if loss reserves prove to be higher than actual claim payments. If net income is insufficient to absorb a required increase in loss reserves, we would incur an operating loss and could incur a reduction in capital.
We may be adversely impacted by inflation.

Our operations, like those of other insurerinsurers and reinsurers, are susceptible to the effects of inflation because premiums are established before the ultimate amounts of losslosses and loss adjustment expenseexpenses are known. Although we consider the potential effects of inflation when setting premium rates, our premiums may not fully offset the effects of inflation and thereby essentially result in our underpricing the risks we insure and reinsure. Our reserve for losses and loss adjustment expenses includesLoss reserves include assumptions about future payments for settlement of claims and claims-handling expenses, such as the value of replacing property, and associated labor costs for the property business we write and litigation costs. To the extent inflation causes costs to increase above loss reserves established for claims, we will be required to increase our loss reserves with a corresponding reduction in our net income in the period in which the deficiency is identified, which may have a material adverse effect on our financial condition or results of operations.operations or financial condition. Unanticipated higher inflation could also lead to higher interest rates, which would negatively impact the value of our fixed income securities and potentially other investments.


The failure of our loss limitation strategy could have a material adverse effect on our results of operations, financial condition, or financial condition.liquidity.
We seek to mitigate our loss exposure through multiple methods. For example, we write a number of our (re)insurancereinsurance contracts on an excess of loss basis. Excess of loss (re)insurancereinsurance indemnifies the insured against losses in excess of a specified amount. We generally limit the line size for each client and line of business on our insurance business and purchase reinsurance for many of our lines of business. In the case of proportional reinsurance treaties, we seek per occurrence limitations or losslosses and loss expenseexpenses ratio caps to limit the impact of losses from any one event. In proportional reinsurance, the reinsurer shares a proportional part of the premiums and losses of the reinsured. We also seek to limit our loss exposure through geographic diversification. Geographic zone limitations involve significant underwriting judgments, including the determination of the area of the zones and the inclusion of a particular policy within a particular zone’s limits. In addition, various provisions of our insurance policies and reinsurance contracts, such as limitations or exclusions from coverage or choice of forum negotiated to limit our risks may not be enforceable in the manner we intend. We cannot be sure that these


loss limitation methods will effectively prevent a material loss exposure which could have a material adverse effect on our results of operations, financial condition, or financial condition.liquidity.
If we choose to purchase reinsurance, we may be unable to do so, and if we successfully purchase reinsurance, we may be unable to collect amounts due to us.so.
We purchase reinsurance for our (re)insurance and reinsurance operations in order to mitigate the volatility of losses uponon our financial results. From time to time, market conditions have limited, and in some cases have prevented, (re)insurers and reinsurers from obtaining the types and amounts of reinsurance that they consider adequate for their business needs. There is no guarantee that our desired amounts of reinsurance or retrocessional reinsurance will be available in the marketplace in the future. In addition to capacity risk, the remaining capacity may not be on terms we deem appropriate or acceptable or with companies with whom we want to do business.
A reinsurer’s insolvency, or inability or refusal to make payments under the terms of its reinsurance agreement with us, could have a material adverse effect on our business because we remain liable to the insured. We face counterparty risk whenever we purchase reinsurance or retrocessional reinsurance. Consequently, the insolvency, inability or unwillingness of any of our present or future reinsurers to make timely payments to us under the terms of our reinsurance or retrocessional agreements could have an adverse effect on our financial condition or results of operations.
We utilize models to assist our decision making in key areas such as underwriting, reserving, reinsurance purchasing and the evaluation of our catastrophe risk but actual results could differ materially from model output.
We employ various modeling techniques (e.g.(for example, scenarios, predictive, stochastic and/or forecasting) to analyze and estimate exposures, loss trends and other risks associated with our assets and liabilities. We utilize modeled outputs and related analyses to assist us in decision-making, for example, related to underwriting and pricing, reserving, reinsurance purchasing and the evaluation of our catastrophe risk through estimates of probable maximum losses, or "PMLs". The modeled outputs and related analyses, both from proprietary and third partythird-party models, are subject to various assumptions, professional judgment, uncertainties and the inherent limitations of any statistical analysis, including the use and quality of historical internal and industry data. Consequently, our actual losses from loss events, whether from individual components (e.g.(for example, wind, flood, earthquake, etc.) or in the aggregate, may differ materially from our modeled results. If, based upon these models or other factors, we misprice our products or underestimate the frequency and/or severity of loss events, our results of operations, or financial condition, or liquidity may be adversely affected.
With respect to the evaluation of our catastrophe risk, our modeling utilizes a mix of historical data, scientific theory and mathematical methods. Output from multiple commercially available vendor models serves as a key input in our PML estimation process. We believe that there is considerable uncertainty in the data and parameter inputs for these vendor models. In that regard, there is no universal standard in the preparation of insured data for use in the models and the running of modeling software. In our view, the accuracy of the models depends heavily on the availability of detailed insured loss data from actual recent large catastrophes. Due to the limited number of events, there is significant potential for substantial differences between the modeled loss estimate and actual company experience for a single large catastrophe event. This potential difference could be even greater for perils with limited or no modeled annual frequency. We perform our own vendor model validation (including sensitivity analysis and backtesting, where possible) and supplement model output with historical loss information and analysis and management judgment. In addition, we derive our own estimates for non-modeled perils. Despite this, our PML estimates are subject to a high degree of uncertainty and our actual losses from catastrophe events may differ materially.
The risk associated with reinsurance underwriting could adversely affect us.
We do not always separately evaluate each of the individual risks assumed under reinsurance treaties, which is common amongst reinsurers. Therefore, we are largely dependent on the original underwriting decisions made by ceding companies. We are subject to the risk that the ceding companies may not have adequately evaluated the risks to be reinsured and that the premiums ceded may not adequately compensate us for the risks we assume. We also have exposure to a range of risks in connection with alternative capital arrangements.
We could be materially adversely affected if managing general agents, general agents, coverholders, other producers and third partythird-party administrators in our program business exceed their underwriting and/or claims settlement authorities or otherwise breach obligations owed to us.


In program business conducted by ourthe insurance segment, following our underwriting, financial, claims and information technology due diligence reviews, we authorize managing general agents, general agents, coverholders and other producers to write business on our behalf within underwriting authorities prescribed by us. Once a program/coverholder commences, we


must rely on the underwriting controls of these entities to write business within the underwriting authorities provided by us. Although we monitor our programs/coverholders on an ongoing basis, our monitoring efforts may not be adequate or these entities may exceed their underwriting or claims settlement authorities or otherwise breach obligations owed to us. To the extent that these entities exceed their authorities or otherwise breach obligations owed to us in the future, our results of operations andor financial condition could be materially adversely affected.
Strategic Risk
Strategic risks are risks that affect or are created by an organization’s business strategy and strategic objectives. Our review of strategic risk is a broad one that evaluates not only internal and external challenges that might cause our chosen strategy to fail but also evaluates major risks that could affect our long-term position and performance.
Competition and consolidation in the insurance/reinsurance industry could reduce our growth and profitability.
The insurance/reinsurance industry is highly competitive. We compete on an international and regional basis with major U.S., Bermuda, European and other international insurers and reinsurers and underwriting syndicates, including Lloyd's, some of which have greater financial, marketing and management resources than we do. We also compete with new companies that continue to be formed to enter the insurance/reinsurance markets. In addition, capital market participants have created alternative products that are intended to compete with insurance and reinsurance products. New and alternative capital inflows in the insurance/reinsurance industry and the retention by insured and cedants of more business have caused an excess supply of insurance and reinsurance capital. There has been a large amount of merger and acquisition activity in the insurance/reinsurance sector in recent years, which may continue; we may experience increased competition as a result of that consolidation with consolidated entities having enhanced market power. Increased competition could result in fewer submissions, lower premium rates, less favorable policy terms and conditions and greater costs of customer acquisition and retention. In addition, if industry pricing does not meet our hurdle rate, we may reduce our future underwriting activities. These factors could have a material adverse effect on our growth and profitability.
Global economic conditions could materially and adversely affect our business, results of operations or financial condition.
Worldwide financial markets can be volatile. In 2008 and 2009, for example, there was volatility and disruption including, among other things, dislocation in the mortgage and asset-backed securities markets, deleveraging and decreased liquidity generally, widening of credit spreads, bankruptcies and government intervention in a number of large financial institutions. These events resulted in extraordinary responses by governments worldwide, including the enactment of the Emergency Economic Stabilization Act of 2008 and the U.S. Recovery and Reinvestment Act in 2009 and Dodd Frank. Uncertainty and market turmoil has affected and may in the future affect, among other aspects of our business, the demand for and claims made under our products, the ability of customers, counterparties and others to establish or maintain their relationships with us, our ability to access and efficiently use internal and external capital resources and our investment performance and portfolio. We also provide coverage to the mortgage industry through insurance and reinsurance of mortgage insurance companies and U.S. government sponsored entity credit risk sharing transactions, and deteriorating economic conditions could cause mortgage insurance losses to increase and adversely affect our results of operations or financial condition.
In addition, steps taken by governments to stabilize financial markets and improve economic conditions may be ineffective and actual or anticipated efforts to continue to unwind some of such steps could disrupt financial markets and/or could adversely impact the value of our investment portfolio. While inflation has recently been moderate and that trend may continue, it is possible that expansionary monetary policies, recent changes to the U.S. tax law, improving economic conditions, higher commodity prices and tighter labor markets could lead to an inflationary environment.
Given the ongoing global economic uncertainties, evolving market conditions may continue to affect our results of operations, financial condition, and capital resources. In the event that there is additional deterioration or volatility in financial markets or general economic conditions, our results of operations, financial condition, capital resources, and competitive landscape could be materially and adversely affected.


Acquisitions that we made or may make could turn out to be unsuccessful.
As part of our strategy, we have pursued and may continue to pursue growth through acquisitions. For example, as part of our strategy to develop a market leading international specialty insurance business, we acquired Novae Group plc, a specialty insurer and reinsurer that operated through Lloyd's of London in 2017. The negotiation of potential acquisitions as well as the integration of an acquired business or new personnel could result in a substantial diversion of management resources. Successful integration will depend on, among other things, our ability to effectively integrate acquired businesses or new personnel into our existing risk management and financial and operational reporting systems, our ability to effectively manage any regulatory issues created by our entry into new markets and geographic locations, our ability to retain key personnel and other operational and economic factors. There can be no assurance that the integration of acquired businesses or new personnel will be successful, that we will realize anticipated synergies, cost savings and operational efficiencies, or that the business acquired will prove to be profitable or sustainable. The failure to integrate acquired businesses successfully or to manage the challenges presented by the integration process may adversely impact our financial results. Acquisitions could involve numerous additional risks such as potential losses from unanticipated litigation or levels of claims and inability to generate sufficient revenue to offset acquisition costs.
Our ability to grow through acquisitions will depend, in part, on our success in addressing these risks. Any failure by us to effectively implement our acquisitions strategy could have a material adverse effect on our business, results of operations, or financial condition.
We could be adversely affected by the loss of one or more key executives or by an inability to attract and retain qualified personnel or by the inability of an executive to obtain a Bermuda work permit.
Our success depends on our ability to retain the services of our existing key executives and to attract and retain additional qualified personnel in the future. The loss of the services of any of our key executives or the inability to hire and retain other highly qualified personnel in the future could adversely affect our ability to conduct our business. Changes in local employment legislation, taxation and the approach of regulatory bodies to compensation practice within our operating jurisdictions may impact our ability to recruit and retain qualified personnel or the cost to us of doing so. There can be no assurance that we will be successful in identifying, hiring or retaining successors on terms acceptable to us.
With a few exceptions generally under Bermuda law only Bermudians, spouses of Bermudians or Permanent Resident Certificate holders (collectively "Residents") may engage in any gainful occupation in Bermuda without an appropriate governmental work permit. Work permits may be granted or extended by the Bermuda government only upon showing that, after proper public advertisement (in most cases), no Residents who meet the minimum standard requirements for the advertised position have applied for the position. Work permits are generally granted for one, three or five year durations. In January 2013, the Bermuda government abolished term limits, meaning expatriate workers can (subject to the above) continue to be employed in Bermuda indefinitely by reapplying for work permits. This removed the immigration policy put in place in 2001, which limited the total duration expatriate workers could remain in Bermuda. All executive officers who work in our Bermuda office who require work permits have obtained them.
The exit of the U.K. from the E.U. could adversely affect us.
On June 23, 2016, the U.K. voted in favor of Brexit. In March 2017, the U.K. government gave official notice of its intention to leave the E.U., commencing the period of up to two years during which the U.K. and the E.U. would negotiate the terms of the U.K.’s withdrawal from the E.U. On October 17, 2019, the U.K. and the E.U. approved a revised withdrawal agreement pertaining to Brexit, which was ratified by the U.K. Parliament and the Council of the European Union on January 31, 2020. This agreement provides for a transition period that will last until at least December 31, 2020, which period may be extended through December 31, 2022; however, the U.K. and the E.U. must make a decision as to whether to so extend by July 1, 2020. During this transition period, the U.K. will remain within the European Single Market, and the services provided to clients and brokers should remain unaffected by these circumstances. Nevertheless, we have significant operations in the U.K. and other E.U. member states. Depending on the final terms of Brexit, we may be required to reorganize our operations and/or to capitalize U.K. branch activities in a manner that could be less efficient and more expensive.
Any of these effects of Brexit, and others we cannot anticipate, could adversely affect our business, results of operations, or financial condition.



Since we depend on a few brokers for a large portion of our revenues, loss of business provided by any one of them could adversely affect us.
We market our insurance and reinsurance products worldwide primarily through insurance and reinsurance brokers and derive a significant portion of our business from a limited number of brokers. Marsh & McLennan Companies, Inc., including its subsidiary Guy Carpenter & Company, Inc., Aon plc and Willis Towers Watson PLC, provided 47% of gross premiums written in 2019. Our relationships with these brokers are based on the quality of our underwriting and claims services, as well as our financial strength ratings. Any deterioration in these factors could result in the brokers advising our clients to place their business with other insurers and reinsurers. In addition, these brokers also have, or may in the future acquire, ownership interests in insurance and reinsurance companies that may compete with us; these brokers may then favor their own insurers and reinsurers over other companies. Loss of all or a substantial portion of the business provided by one or more of these brokers could have a material adverse effect on our business.
A downgrade in our financial strength or credit ratings by one or more rating agencies could materially and negatively impact our business, results of operations, financial condition, or liquidity.
Our ability to underwrite business is dependent upon the quality of our claims paying and financial strength ratings as evaluated by independent rating agencies. A downgrade, withdrawal or negative watch/outlook by any of these institutions could cause our competitive position in the insurance/reinsurance industry to suffer and make it more difficult for us to market our products. If we experience a credit rating downgrade, withdrawal or negative watch/outlook in the future, we could incur higher borrowing costs and may have more limited means to access capital. A downgrade, withdrawal or negative watch/outlook could also result in a substantial loss of business for us, as ceding companies and brokers that place such business may move to other insurers and reinsurers with higher ratings. We would also be required to post collateral under the terms of certain of our policies of reinsurance.
We may require additional capital in the future, which may not be available or may only be available on unfavorable terms.
Our future capital requirements depend on many factors, including rating agency and regulatory requirements, the performance of our investment portfolio, our ability to write new business successfully, the frequency and severity of catastrophe events and our ability to establish premium rates and loss reserves at levels sufficient to cover losses. We may need to raise additional funds through financings. If we are unable to do so, it may curtail our ability to conduct our business. Any equity or debt financing, if available at all, may be on terms that are not favorable to us. Equity financings could be dilutive to our existing shareholders and could result in the issuance of securities that have rights, preferences and privileges that are senior to those of our other securities. If we cannot obtain adequate capital on favorable terms or at all, our business, operating results and financial condition could be adversely affected.
Our inability to obtain the necessary credit could affect our ability to offer reinsurance in certain markets.
Neither AXIS Specialty Bermuda nor AXIS Re SE is licensed or admitted as an insurer or reinsurer in any jurisdiction other than Bermuda, Ireland, Singapore and Brazil. Because the U.S. and some other jurisdictions do not permit insurance companies to take credit on their statutory financial statements for reinsurance obtained from unlicensed or non-admitted insurers unless appropriate security mechanisms are in place, our reinsurance clients in these jurisdictions typically require AXIS Specialty Bermuda and AXIS Re SE to provide letters of credit or other collateral. Our credit facilities are used to post letters of credit. However, if our credit facilities are not sufficient or if we are unable to renew our credit facilities or arrange for other types of security on commercially affordable terms, AXIS Specialty Bermuda and AXIS Re SE could be limited in their ability to write business for some of our clients.
Market Risk, and Liquidity Risk
Market risk is the risk that our financial instruments may be negatively impacted by movements in financial market prices or rates such as equity prices, interest rates, credit spreads and foreign exchange rates. Liquidity risk is the risk that we may not have sufficient financial resources to meet our obligations when they fall due, or would have to incur excessive costs to do so.




Our investment and derivative instrument portfolios are exposed to significant capital markets risk related to changes in interest rates, credit spreads and equity prices, as well as other risks, which may adversely affect our results of operations or financial condition.
The performance of our cash and investments portfolio has a significant impact on our financial results. A failure to successfully execute our investment strategy could have a significant impact on our results of operations or financial condition.
Our investment portfolio is subject to a variety of market risks, including risks relating to general economic conditions, interest rate fluctuations, equity price risk, foreign currency movements, pre-payment or reinvestment risk, liquidity risk and credit risk. Although we manage market risks through, among other things, stressing diversification and conservation of principal and liquidity in our investment guidelines, it is possible that, in periods of economic weakness or periods of turmoil in capital markets, we may experience significant losses in our portfolio.
Our fixed maturities, which represent 87% of our total investments and 78% of total cash and investments at December 31, 2019, may be adversely impacted by changes in interest rates. Increases in interest rates could cause the fair value of our investment portfolio to decrease, resulting in a lower book value (refer to Item 7A 'Quantitative and Qualitative Disclosure About Market Risk' for further details) and capital resources. In addition, a lower interest rate environment can result in reductions in our investment yield as new funds and proceeds from sales and maturities of fixed income securities are reinvested at lower rates. This reduces our overall future profitability. Interest rates are highly sensitive to many factors, including governmental and central bank monetary policies, inflation, domestic and international economic and political conditions and other factors beyond our control.
Our portfolios of "other investments" and equity securities expose us to market price variability, driven by a number of factors outside our control including, but not limited to global equity market performance. Given our reliance on external investment managers, we are also exposed to operational risks, which may include, but are not limited to a failure to follow our investment guidelines, technological and staffing deficiencies and inadequate disaster recovery plans.
Our derivative instrument counterparties may default on amounts owed to us due to bankruptcy, insolvency, lack of liquidity, adverse economic conditions, operational failure, fraud or other reasons. Even if we are entitled to collateral in circumstances of default, such collateral may be illiquid or proceeds from such collateral when liquidated may not be sufficient to recover the full amount of the obligation.
Changes in the method for determining LIBOR and the potential replacement of LIBOR may affect our cost of capital and net investment income.
On July 27, 2017, the FCA announced its intention to cease sustaining LIBOR after 2021. The FCA has statutory powers to require panel banks to contribute to LIBOR where necessary. The FCA has decided not to ask, or to require, that panel banks continue to submit contributions to LIBOR beyond the end of 2021. The FCA has indicated that it expects that the current panel banks will voluntarily sustain LIBOR until the end of 2021. The FCA’s intention is that after 2021, it will no longer ask, or require, banks to submit contributions to LIBOR. It is possible that the IBA and the panel banks could continue to produce LIBOR on the current basis after 2021, if they are willing and able to do so, but we believe it is unlikely that LIBOR will survive in its current form, or at all.
Uncertainty as to the nature of such potential changes, alternative reference rates or other reforms may adversely affect the trading market for LIBOR-based securities, including those held in our investment portfolio. Changes or reforms to the determination or supervision of LIBOR or successor reference rate may result in a sudden or prolonged increase or decrease in reported LIBOR or to a successor, which could have an adverse impact on the market for floating rate securities and the value of our investment portfolio and insurance products which directly or indirectly reference LIBOR or its successor.
At December 31, 2019, our investment portfolio included $1.8 billion of floating rate investments for which the interest rate was tied to LIBOR. The instruments and agreements governing our investments generally provide for appropriate fall-back language if the current index is no longer available, however there is no assurance that the alternative index will provide comparable returns. There is currently no definitive information regarding the future utilization of LIBOR or of any particular replacement rate. As such, the potential effect of any such event on net investment income cannot yet be determined and any changes to benchmark interest rates could decrease net investment income, which could impact our results of operations, liquidity, or the market value of our investments.


Our operating results may be adversely affected by currency fluctuations.
Our reporting currency is the U.S. dollar. However, a portion of gross premiums are written and ceded in currencies other than the U.S. dollar and a portion of gross and ceded loss reserves are in non-U.S. currencies. In addition, a portion of our investment portfolio is denominated in currencies other than the U.S dollar. From time to time, we may experience losses resulting from fluctuations in the values of these non-U.S. currencies, which could adversely affect our operating results. Although we manage our foreign currency exposure through matching of our major foreign-denominated assets and liabilities, as well as through use of currency derivatives, there is no guarantee that we will successfully mitigate our exposure to foreign exchange losses. Sovereign debt concerns in Europe and related financial restructuring efforts, which may cause the value of the euro to deteriorate, and Brexit, which caused significant volatility in currency exchange rates, especially between the U.S. dollar and the British pound, may magnify these risks.
Our underwriting activities may expose us to liquidity risks.
Our exposure to liquidity risk stems mainly from the need to cover potential extreme loss events and regulatory constraints that limit the flow of funds within the Group. We maintain cash and cash equivalents and high quality, liquid investment portfolios to meet expected outflows, as well as those that could result from a range of potential stress events. We place internal limits on the maximum percentage of cash and investments which may be in an illiquid form as well as on the minimum percentage of our asset portfolio which may be invested in unrestricted cash and liquid investment grade fixed income securities.
Additionally, we maintain committed borrowing facilities, as well as access to diverse funding sources to cover contingencies. Funding sources include asset sales, external debt issuances and lines of credit. We conduct stress tests to ensure the sufficiency of these funding sources in extreme scenarios; however, there remains a risk that in certain circumstances, our results of operations or financial condition may be adversely impacted by our inability to access appropriate liquidity, or the cost of doing so.
Credit Risk
Credit risk represents the risk of incurring financial loss due to the diminished creditworthiness (eroding credit rating and, ultimately, default) of our third-party counterparties.
If we successfully purchase reinsurance, we may be unable to collect amounts due to us.
A reinsurer’s insolvency, or inability or refusal to make payments under the terms of its reinsurance agreement with us, could have a material adverse effect on our business because we remain liable to the insured. We face counterparty risk whenever we purchase reinsurance or retrocessional reinsurance. Consequently, the insolvency, inability or unwillingness of any of our present or future reinsurers to make timely payments to us under the terms of our reinsurance or retrocessional agreements could have an adverse effect on our results of operations, financial condition, or liquidity.
Our reliance on brokers subjects us to credit risk.
In accordance with industry practice, we pay amounts owed on claims under our insurance and reinsurance contracts to brokers, and these brokers pay these amounts over to the clients that have purchased insurance and reinsurance from us. Although the law is unsettled and depends upon the facts and circumstances of the particular case, in some jurisdictions, if a broker fails to make such a payment, we might remain liable to the insured or ceding insurer for the deficiency.
Conversely, in certain jurisdictions, when the insured or ceding insurer pays premiums for these policies to brokers for payment over to us, these premiums might be considered to have been paid to us and the insured or ceding insurer will no longer be liable to us for those amounts, whether or not we have actually received the premiums from the broker. Consequently, we assume a degree of credit risk associated with brokers with whom we transact business. These risks are heightened during periods characterized by financial market instability and/or an economic downturn or recession.


Certain of our policyholders and intermediaries may not pay premiums owed to us due to insolvency or other reasons.
Insolvency, liquidity problems, distressed financial condition or the general effects of economic recession may increase the risk that policyholders or intermediaries, such as insurance brokers, may not pay a part of or the full amount of premiums owed to us, despite an obligation to do so. The terms of our contracts may not permit us to cancel our insurance even though we have not received payment. If non-payment becomes widespread, whether as a result of insolvency, lack of liquidity, adverse economic conditions, operational failure or otherwise, it could have a material adverse impact on our revenues and results of operations.
Operational Risk
Operational risk represents the risk of financial loss as a result of inadequate processes, system failures, human error or external events.
If we experience difficulties with technology and/or data security, our ability to conduct our business might be negatively impacted.
While technology can streamline many business processes and ultimately reduce the cost of operations, technology initiatives present certain risks. Our business is dependent upon our employees’ and outsourcers’ ability to perform, in an efficient and uninterrupted fashion, necessary business functions such as processing policies and paying claims. A shutdown or inability to access one or more of our facilities, a power outage, or a failure of one or more of our information technology, telecommunications or other systems could significantly impair our ability to perform such functions on a timely basis. If sustained or repeated, such a business interruption, system failure or service denial could result in a deterioration of our ability to write and process business, provide customer service, pay claims in a timely manner or perform other necessary business functions. Unauthorized access, computer viruses, deceptive communications (phishing), malware, hackers and other external hazards including catastrophe events could expose our data systems to security breaches. These risks could expose us to data loss and damages. As a result,
Like other global companies, we may be regularly the target of attempted cyber and other security threats and must continuously monitor and develop our abilityinformation technology networks and infrastructure to conductprevent, detect, address and mitigate the risk of threats to our business might be adversely affected.
While we have not experienced a material breach of cybersecurity to date, we have no assurance that such a breach will not occur in the future.data and systems. Over time, and particularly recently, the sophistication of these threats continues to increase. While administrative and technical controls, along with other preventive actions, reduce the risk of cyber incidents and protect our information technology, they may be insufficient to preventthwart cyber attacks and/or prevent other security breaches to our computer systems.
To the extent any disruption or security breach results in a loss or damage to our data, or inappropriate disclosure of our confidential information or that of others, it could impact our operations, cause significant damage to our reputation, affect our relationships with our customers and clients, lead to claims against us under various data privacy laws, result in regulatory action and ultimately have a material adverse effect on our business or operations. In addition, although we purchase limited cyber insurance, we may be required to incur significant costs to mitigate the damage caused by any security breach, to address any interruptions in our business, or to protect against future damage, which costs may not be covered by our cyber insurance.
We also operate in a number of jurisdictions with strict data privacy and other related laws, which could be violated in the event of a significant cybersecurity incident, or by personnel. Failure to comply with these obligations can give rise to monetary fines and other penalties whichthat could be significant.
Our business may be adversely affected if third-party outsourced service providers fail to satisfactorily perform certain technology and business process functions.
We outsource certain technology and business process functions to third parties and may do so increasingly in the future.parties. If we do not effectively develop and implement our outsourcing strategy, third partythird-party providers do not perform as anticipated or we experience technological or other problems with a transition, we may not realize productivity improvements or cost efficiencies and may experience operational difficulties, increased costs and a loss of business. Our outsourcing of certain technology and business process functions to third parties may expose us to enhanced risk related to data security, which could result in monetary and reputational damages. In addition, our ability to receive services from third partythird-party providers might be impacted by cultural differences, political instability or unanticipated regulatory requirements or policies.requirements. As a result, our ability to conduct our business might be adversely affected.
Our operating results may be adversely affected by currency fluctuations.
Our reporting currency is
We rely on internal processes to maintain our operations and manage the U.S. dollar. However, a portion ofoperational risks inherent to our gross premiums are written in currencies other than the U.S. dollar and a portion of our loss reserves are in non-U.S. currencies. In addition, a portion of our investment portfolio is denominated in currencies other than the U.S dollar. From time to time, we may experience losses resulting from fluctuationsbusiness; employee misconduct, errors or omissions in the valuesexecution of these non-U.S. currencies, whichprocesses may result in financial losses.
We rely on the execution of internal processes to maintain and execute our operations. We seek to monitor and control our exposure to risks arising from these processes through an enterprise risk management framework, internal controls, management review and other processes. We cannot provide total assurance that these processes will effectively identify or control all risks, or that our employees and third-party agents will effectively execute them. Loss may result from, among other things, fraud; errors; or failure to document transactions properly, obtain proper internal authorization, comply with underwriting or other internal guidelines, or comply with regulatory requirements. These risks could result in losses that adversely affect our operating results. Althoughbusiness, results of operations, or financial condition. Furthermore, insurance policies provided by third parties may not cover us if we attempt to manage our foreign currency exposure through matching of our major foreign-denominated assets and liabilities, as well as through use of currency derivatives, there is no guarantee that we will successfully mitigate our exposure to foreign exchange losses. Sovereign debt concerns in Europe and related financial restructuring efforts, which may cause the value of the euro to deteriorate, and Brexit (defined below), which causedexperience a significant volatility in currency exchange rates, especially between the U.S. dollar and the British pound, may magnifyloss from these risks.
Acquisitions that we madeRegulatory Risks
Regulatory risk means the risk arising from our failure to comply with legal, statutory or regulatory obligations
Compliance with laws and regulations governing the processing of personal data and information may make could turn outimpede our services or result in increased costs. Failure to be unsuccessful.


As part of our strategy, we have pursuedcomply with these data privacy laws and may continue to pursue growth through acquisitions. For example, as part of AXIS Insurance's international specialty insurance growth strategy, in 2017, we acquired Novae Group plc, a specialty (re)insurer that operates through Lloyd's of London. The negotiation of potential acquisitions as well as the integration of an acquired business or new personnelregulations could result in a substantial diversionmaterial fines or penalties imposed by data protection or financial services conduct regulators and/or awards of management resources. Successful integration will depend on, among other things, our ability to effectively integrate acquired businesses or new personnel into our existing risk managementcivil damages and financial and operational reporting systems, our ability to effectively manage any regulatory issues created by our entry into new markets and geographic locations, our ability to retain key personnel and other operation economic factors. There can be no assurance that the integration of acquired businesses, including Novae Group plc, or new personnel will be successful, that we will realize anticipated synergies, cost savings and operational efficiencies, or that the business acquired will prove to be profitable or sustainable. The failure to integrate acquired businesses successfully or to manage the challenges presented by the integration processdata breach may adversely impact our financial results. Acquisitions could involve numerous additional risks such as potential losses from unanticipated litigation or levels of claims and inability to generate sufficient revenue to offset acquisition costs.
Our ability to grow through acquisitions will depend, in part, on our success in addressing these risks. Any failure by us to effectively implement our acquisitions strategy could have a material adverse effect on our business,reputation, results of operations, or financial condition, or resultshave other adverse consequences.
Our business relies on the processing of operations.

data in many jurisdictions and the movement of data across national borders. The collection, storage, handling, disclosure, use, transfer and security of personal information that occurs in connection with our business is subject to federal, state and foreign data privacy laws. These legal requirements are not uniform and continue to evolve, and regulatory scrutiny in this area is increasing around the world. In many cases, these laws apply not only to third-party transactions, but also to transfers of information among the Company and its subsidiaries. Privacy and data protection laws may be interpreted and applied differently from country to country and may create inconsistent or conflicting requirements.
The eventual exitGeneral Data Privacy Regulation ("GDPR") has extra-territorial effect. It requires all companies processing data of E.U. citizens to comply with the GDPR, regardless of the U.K. fromcompany’s location; it also imposes obligations on E.U. companies processing data of non-E.U. citizens. The GDPR imposes requirements regarding the European Union could adversely affect us.

On June 23, 2016,processing of personal data and confers new rights on data subjects, including rights of access to their personal data, deletion of their personal data, the U.K. voted"right to exit the E.U. ("Brexit") and in March 2017, the U.K. government gave official notice of its intention to leave the E.U., commencing the period of up to two years during which the U.K.be forgotten" and the E.U. would negotiateright to "portability" of personal data.
The California Consumer Privacy Act ("CCPA") came into force on January 1, 2020 and confers rights on Californian residents including rights to know what personal information is collected about them, whether their personal information is sold and if so, to whom, to access their personal information that has been collected and to require a business to delete their personal information.
Compliance with the termsenhanced obligations imposed by the GDPR, the CCPA and other legislation (including Bermuda’s Personal Information Protection Act) requires investment in appropriate technical or organizational measures to safeguard the rights and freedoms of data subjects, may result in significant costs to our business and may require us to modify certain of our business practices. Enforcement actions, investigations and the U.K.’s withdrawal fromimposition of substantial fines and penalties by regulatory authorities as a result of data security incidents and privacy violations have increased dramatically over the E.U.past several years. The effectsenactment of Brexit will dependmore restrictive laws, rules, regulations, or future enforcement actions or investigations could impact us through increased costs or restrictions on any agreementsour business, and noncompliance could result in regulatory penalties and significant legal liability.
In addition, unauthorized disclosure or transfer of sensitive or confidential client or Company data, whether through systems failure, employee negligence, fraud or misappropriation, by the U.K. makesCompany or other parties with whom we do business, could subject us to retain access to E.U. markets either during a transitional periodsignificant litigation, monetary damages, regulatory enforcement actions, fines and criminal prosecution in one or more permanently.

The Brexit vote had an immediatejurisdictions. Such events could also result in negative publicity and damage to our reputation and cause us to lose business, which could therefore have a material adverse effect on global financial markets, including foreign currency markets, and could continue to contribute to instability in global financial markets and in European and worldwide economic or market conditions, both during and after the Brexit process. The long-term effect of Brexit on the value of our investment portfolio at this time is uncertain and such volatility and uncertainty will likely continue as negotiations progress to determine the future terms of the U.K.’s relationship with the E.U. In addition, Brexit could lead to legal and regulatory uncertainty and potentially divergent national laws and regulations as the U.K. determines which E.U. laws to replace or replicate and the E.U. determines access rights and limitations.

We have significant operations in the U.K. and other E.U. member states. Depending on the final terms of Brexit, we may be required to reorganize our operations, legal entity structure and capitalization in the U.K. and the E.U. in a manner that could be less efficient and more expensive. Brexit may disrupt our U.K. domiciled entities’, including our Lloyd’s managing agency and its syndicates', ability to "passport" within the E.U., which is the system by which our insurance entities currently provide insurance across E.U. member states while only being subject to regulation by their "home state" regulators. Brexit may disrupt the ability of our E.U. operating entities to access U.K. business.

Any of these effects of Brexit, and others we cannot anticipate, could adversely affect our business, business opportunities, results of operations or financial condition and cash flows.
We may require additional capital in the future, which may not be available or may only be available on unfavorable terms.
Our future capital requirements depend on many factors, including rating agency and regulatory requirements, the performance of our investment portfolio, our ability to write new business successfully, the frequency and severity of catastrophe events and our ability to establish premium rates and reserves at levels sufficient to cover losses. We may need to raise additional funds through financings. If we are unable to do so, it may curtail our ability to conduct our business. Any equity or debt financing, if available at all, may be on terms that are not favorable to us. Equity financings could be dilutive to our existing shareholders and could result in the issuance of securities that have rights, preferences and privileges that are senior to those of our other securities. If we cannot obtain adequate capital on favorable terms or at all, our business, operating results and financial condition could be adversely affected.condition.


Our inability to obtain the necessary credit could affect our ability to offer reinsurance in certain markets.
Neither AXIS Specialty Bermuda nor AXIS Re SE is licensed or admitted as a (re)insurer in any jurisdiction other than Bermuda, Ireland, Singapore and Brazil. Because the U.S. and some other jurisdictions do not permit insurance companies to take credit on their statutory financial statements for reinsurance obtained from unlicensed or non-admitted insurers unless appropriate security mechanisms are in place, our reinsurance clients in these jurisdictions typically require AXIS Specialty Bermuda and AXIS Re SE to provide letters of credit or other collateral. Our credit facilities are used to post letters of credit. However, if our credit facilities are not sufficient or if we are unable to renew our credit facilities or arrange for other types of security on commercially affordable terms, AXIS Specialty Bermuda and AXIS Re SE could be limited in their ability to write business for some of our clients.
The regulatory system under which we operate, and potential changes thereto, could have a material adverse effect on our business.
In a time of financial uncertainty or a prolonged economic downturn or recession, regulators may choose to adopt more restrictiveOur insurance laws and regulations, which may result in lower revenues and/or higher costs and thus could materially and adversely affect our results of operations.
Our (re)insurancereinsurance subsidiaries conduct business globally and we are subject to varying degrees of regulation and supervision from thesein multiple jurisdictions. In the U.K., Lloyd's has supervisory powers that pose unique regulatory risks. The laws and regulations of the jurisdictions and markets, including Lloyd's in which our (re)insurance and reinsurance subsidiaries are domiciled or operate require, among other things, that our subsidiaries maintain minimum levels of statutory capital and liquidity, meet solvency standards, participate in guaranty funds and submit to periodic examinations of their financial condition and compliance with underwriting and other regulations. These laws and regulations also limit or restrict payments of dividends and reductions in capital. Statutes, regulations and policies may also restrict the ability of these subsidiaries to write (re)insurance and reinsurance contracts, to make certain investments and to distribute funds. The purpose of insurance laws and regulations generally is to protect insureds and ceding insurance companies, not our shareholders. We may not be able to comply fully with, or obtain appropriate exemptions from, these statutes and regulations. Failure to comply with or to obtain appropriate authorizations and/or exemptions under any applicable lawsregulations, which could result in restrictions on our ability to do business or undertake activities that are regulated in one or more of the jurisdictions in which we conduct business and could subject us to fines and other sanctions. In addition, changes in the laws or regulations to which our (re)insurance and reinsurance subsidiaries are subject or in the interpretation thereof by enforcement or regulatory agencies could have an adverse effect on our business.
As a result of the Novae acquisition, our presence at Lloyd's has substantially increased. Lloyd's has supervisory powers that pose unique regulatory risks. These relate to:
Capital - Lloyd's can vary the method by which they solvency capital requirement is calculated; be subject to a reduced ability to trade in certain classes of business at current levels as a consequence of downgrading of the Lloyd's market; experience reduced underwriting capacity due to a reduction in the funds held in trust at Lloyd's (as a result of changes in the market value of investments or otherwise).
Licensing - Lloyd's licenses may not be available or be subject to revised conditions by events such as: credit downgrading of Lloyd's reducing the ability to trade in certain classes of business at current levels; being required by U.S. regulators to increase the level of funding required as minimum deposits for the protection of U.S. policyholders.
Lloyd's Oversight - being subject to potential changes in business strategy due to requirements of the Lloyd's Franchise Board (which is responsible for the day-to-day management of the Lloyd's market); modification or rejection by Lloyd's of the annual syndicate business plan or proposals by our managing agency to change the plan.
Reputational - issues arising from the actions of other Lloyd's syndicates or actions against the Lloyd's franchise as a whole.


Potential government intervention in our industry as a result of recent events and instability in the marketplace for insurance products could hinder our flexibility and negatively affect the business opportunities that may be available to us in the market.
Government intervention and the possibility of future government intervention have created uncertainty in the (re)insuranceinsurance/ reinsurance markets. Government and regulators are generally concerned with having (re)insurers and reinsurers with high solvency ratios and localized capital to ensure the protection of policyholders to the possible detriment of other constituents, including shareholders of (re)insurers. An example of such intervention was the December 2007 extension of the material provisions of TRIA for an additional seven years to December 31, 2014insurers and expansion of coverage to include domestic acts of terrorism. TRIEA expired at the end of 2014 but was reauthorized, with some adjustments to its provisions, in January 2015 for six years through December 31, 2020.reinsurers.
In recent years certain U.S. and non-U.S. judicial and regulatory authorities, including U.S. Attorney’s Offices and certain state attorneys general, have commenced investigations into other business practices in the insurance industry. In addition, although the U.S. federal government has not historically regulated insurance, there have been proposals from time to time, and especially after the most recent global financial crisis, to impose federal regulation on the U.S. insurance industry. For example, in 2010, Dodd-Frank established a Federal Insurance Office ("FIO") within the U.S. Treasury. The FIO has limited regulatory authority and is empowered to gather data and information regarding the insurance industry, and has conducted and submitted a study to the U.S. Congress on how to modernize and improve insurance regulation in the U.S. This study's findings are not expected to have a significant impact on the Company. Further, Dodd-Frank gives the Federal Reserve supervisory authority over a number of U.S. financial services companies, including insurance companies, if they are designated by a two-thirds vote of a Financial Stability Oversight Council as ‘systemically important’. While we do not believe that we are systemically important, as defined in Dodd-Frank, Dodd-Frank or additional federal or state regulation that is adopted in the future could impose significant burdens on us, impact the ways in which we conduct our business and govern our subsidiaries, increase compliance costs, increase the levels of capital required to operate our subsidiaries, duplicate state regulation and/or result in a competitive disadvantage.
Certain of our European legal entities are subject to local laws that implement to the Solvency II Directive. Solvency II covers three main areas: (i) the valuation of assets and liabilities on a Solvency II economic basis and risk basedrisk-based solvency and capital requirements; (ii) governance requirements including requirements relating to the key functionfunctions of compliance, internal audit, actuarial and risk management; and (iii) new supervisory legal entity and group reporting and disclosure requirements including public disclosures. The BMA has been granted full "equivalence"is fully "equivalent" under the Solvency II Directive for Bermuda's commercial insurance sector, including Class 4 insurers, with an effective date of January 1, 2016.insurers.
While we cannot predict the exact nature, timing or scope of possible governmental initiatives, such proposals could adversely affect our business by, among other things:
Providing reinsurance capacity in markets and to consumers that we target;

Requiring our further participation in industry pools and guaranty associations;

Expanding the scope of coverage under existing policies; e.g., following large disasters;

Further regulating the terms of (re)insurance and reinsurance contracts; or

Disproportionately benefiting the companies of one country over those of another.




Our international business is subject to applicable laws and regulations relating to sanctions and foreign corrupt practices, the violation of which could adversely affect our operations.

We must comply with all applicable economic and financial sanctions, other trade controls and anti-bribery laws and regulations of the U.S. and other foreign jurisdictions where we operate, including Bermuda, the U.K. and the European Community, which apply to our business where we operate.Community. U.S. laws and regulations applicable to us include the economic trade sanctions laws and regulations administered by the U.S. Department of Treasury’s Office of Foreign Assets Control as well as certain laws administered by the U.S. Department of State. In addition, we are subject to the Foreign Corrupt Practices Act and other anti-bribery laws, such as the Bermuda Bribery Act and the U.K. Bribery Act, thatwhich generally bar corrupt payments or unreasonable gifts. Although we have policies and controls in place that are designed to ensure compliance with these laws and regulations, it is possible that an employee or an agent acting on our behalf, could fail to comply with applicable laws and regulations and due to the complex nature of the risks, it may not always be possible for us to ascertain compliance with such laws and regulations. In such event, we could be exposed to civil penalties, criminal penalties and other sanctions, including fines or other unintended punitive actions. In addition, such violations could damage our business and/or our reputation. All of the foregoing could have a material adverse effect on our financial condition and operating results.
SinceFuture changes in current accounting practices may materially impact our reported financial results.
Future changes in accounting practices may result in significant additional expenses and may affect the calculation of financial statement line items. For example, this could occur if we depend on a few brokers for a large portionare required to prepare information relating to prior periods or if we are required to apply new requirements retroactively.
Risks Related to Ownership of our revenues, loss ofSecurities
In addition to the risks to our business provided by any one of them could adversely affect us.
We market our (re)insurance worldwide primarily through (re)insurance brokers and derive a significant portionlisted above, there are certain other risks related to the ownership of our businesssecurities.
The price of our common shares may be volatile.
There has been significant volatility in the market for equity securities in recent years. During 2019, 2018, and 2017 the price of our common shares fluctuated from a limited numberlow of brokers. Marsh & McLennan Companies, Inc., including its subsidiary Guy Carpenter & Company, Inc., Aon plc$50.95 to a high of $67.25, a low of $47.43 to a high of $60.69 and Willis Towers Watson PLC, provided a totallow of 49%$49.42 to a high of $71.06, respectively. The price of our gross premiums written during 2017. Our relationships with these brokers are basedcommon shares may not remain at or exceed current levels. The following factors, in addition to those described in other risk factors above, may have an impact on the qualitymarket price of our underwriting and claim services, as well ascommon stock:
actual or anticipated variations in our financial strength ratings. Any deterioration in these factors could result in the brokers advising our clients to place their business with other (re)insurers. In addition, these brokers also have, or may in the future acquire, ownership interests in insurance and reinsurance companies that may compete with us and these brokers may favor their own (re)insurers over other companies. Loss of all or a substantial portion of the business provided by one or more of these brokers could have a material adverse effect on our business.
Our reliance on brokers subjects us to credit risk.
In accordance with industry practice, we pay amounts owed on claims under our (re)insurance contracts to brokers, and these brokers pay these amounts over to the clients that have purchased (re)insurance from us. Although the law is unsettled and depends upon the facts and circumstances of the particular case, in some jurisdictions, if a broker fails to make such a payment, we might remain liable to the insured or ceding insurer for the deficiency.
Conversely, in certain jurisdictions, when the insured or ceding insurer pays premiums for these policies to brokers for payment over to us, these premiums might be considered to have been paid to us and the insured or ceding insurer will no longer be liable to us for those amounts, whether or not we have actually received the premiums from the broker. Consequently, we assume a degree of credit risk associated with brokers with whom we transact business. These risks are heightened during periods characterized by financial market instability and/or an economic downturn or recession.
Certain of our policyholders and intermediaries may not pay premiums owed to us due to insolvency or other reasons.
Insolvency, liquidity problems, distressed financial condition or the general effects of economic recession may increase the risk that policyholders or intermediaries, such as insurance brokers, may not pay a part of or the full amount of premiums owed to us, despite an obligation to do so. The terms of our contracts may not permit us to cancel our insurance even though we have not received payment. If non-payment becomes widespread, whetherquarterly results, including as a result of insolvency, lackcatastrophes or our investment performance;

Stock markets in the U.S. continue to experience volatile price and volume fluctuations. Such fluctuations, as well as the general political situation, current economic conditions operational failure or otherwise, it could have a material adverse impact on our revenues and results of operations.


We could be adversely affected by the loss of oneinterest rate or more key executives or by an inability to attract and retain qualified personnel.
Our success depends on our ability to retain the services of our existing key executives and to attract and retain additional qualified personnel in the future. The loss of the services of any of our key executives or the inability to hire and retain other highly qualified personnel in the futurecurrency rate fluctuations, could adversely affect the market price of our ability to conduct our business. There can be no assurance that we will be successful in identifying, hiring or retaining successors on terms acceptable to us.stock.
With a few exceptions generally under Bermuda law only Bermudians, spouses of Bermudians or Permanent Resident Certificate holders (collectively "Residents") may engage in any gainful occupation in Bermuda without an appropriate governmental work permit. Work permits may be granted or extended by the Bermuda government only upon showing that, after proper public advertisement (in most cases), no Residents who meet the minimum standard requirements for the advertised position have applied for the position. Work permits are generally granted for one, three or five year durations. In January 2013, the Bermuda government abolished term limits, meaning expatriate workers can (subject to the above) continue to be employed in Bermuda indefinitely by reapplying for work permits. This removed the immigration policy put in place in 2001, which limited the total duration expatriate workers could remain in Bermuda. All executive officers who work in our Bermuda office who require work permits have obtained them.

Our ability to pay dividends and to make payments on indebtedness may be constrained by our holding company structure.
AXIS Capital is a holding company and has no direct operations of its own. AXIS Capital has no significant operations or assets other than its ownership of the shares of its operating (re)insurance and reinsurance subsidiaries, AXIS Specialty Bermuda, AXIS Ventures Re,Reinsurance Limited, AXIS Re SE, AXIS Specialty Europe, Compagnie Belge d'Assurances, Aviation NV/SA, Aviabel Re S.A., the Members of Lloyd's (AXIS Corporate Capital UK Limited and NovaeAXIS Corporate UnderwritingCapital UK II Limited), AXIS Re U.S., AXIS Specialty U.S., AXIS Surplus and AXIS Insurance Co. (collectively, our "Insurance Subsidiaries"). Dividends and other permitted distributions from our Insurance Subsidiaries (in some cases through our subsidiary holding companies), are our primary source of funds to meet ongoing cash requirements, including debt service payments and other expenses, and to pay dividends to our shareholders. Our Insurance Subsidiaries are subject to significant regulatory restrictions limiting their ability to declare and pay dividends and make distributions. The inability of our Insurance Subsidiaries to pay dividends in an amount sufficient to enable us to meet our cash requirements at the holding company level could have a material adverse effect on our business and our ability to pay dividends and make payments on our indebtedness.
AXIS Capital is a Bermuda company and it may be difficult for you to enforce judgments against it or its directors and executive officers.
AXIS Capital is incorporated pursuant to the laws of Bermuda and our business is based in Bermuda. In addition, some of our directors and officers reside outside the U.S., and all or a substantial portion of our assets and the assets of such persons are located in jurisdictions outside the U.S. As a result, it may be difficult or impossible to effect service of process within the U.S. upon those persons or to recover against us or them on judgments of U.S. courts, including judgments predicated upon civil liability provisions of the U.S. federal securities laws. Further, it may not be possible to bring a claim in Bermuda against us or our directors and officers for violation of U.S. federal securities laws because these laws may have no extraterritorial application under Bermuda law and do not have force of law in Bermuda. A Bermuda court may, however, impose civil liability, including the possibility of monetary damages, on us or our directors and officers if the facts alleged in a complaint constitute or give rise to a cause of action under Bermuda law.
There are provisions in our organizational documents that may reduce or increase the voting rights of our shares.
Our bye-laws generally provide that shareholders have one vote for each common share held by them and are entitled to vote, on a non-cumulative basis, at all meetings of shareholders. However, the voting rights exercisable by a shareholder may be limited so that certain persons or groups are not deemed to hold 9.5% or more of the voting power conferred by our shares. Under these provisions, some shareholders may have the right to exercise their voting rights limited to less than one vote per share. Moreover, these provisions could have the effect of reducing the voting power of some shareholders who would not otherwise be subject to the limitation by virtue of their direct share ownership. In addition, our board of directors may limit a shareholder’s exercise of voting rights where it deems it necessary to do so to avoid adverse tax, legal or regulatory consequences.


We also have the authority under our bye-laws to request information from any shareholder for the purpose of determining whether a shareholder’s voting rights are to be limited pursuant to the bye-laws. If a shareholder fails to respond to our request for information or submits incomplete or inaccurate information in response to a request by us, we may, in our sole discretion, eliminate the shareholder’s voting rights.
There are provisions in our bye-laws that may restrict the ability to transfer common shares and which may require shareholders to sell their common shares.
Our board of directors may decline to register a transfer of any common shares under some circumstances, including if they have reason to believe that any non-de minimis adverse tax, regulatory or legal consequences to us, any of our subsidiaries or any of our shareholders may occur as a result of such transfer. Our bye-laws also provide that if our board of directors determines that share ownership by a person may result in non-de minimis adverse tax, legal or regulatory consequences to us, any of our subsidiaries or any of our shareholders, then we have the option, but not the obligation, to require that shareholder to sell to us or to third parties to whom we assign the repurchase right for fair value the minimum number of common shares held by such person which is necessary to eliminate the non-de minimis adverse tax, legal or regulatory consequences.


Applicable insurance laws may make it difficult to effect a change of control of our company.
Before a person can acquire control of a U.S. insurance company, prior written approval must be obtained from the insurance commissioner of the state where the domestic insurer is domiciled. Prior to granting approval of an application to acquire control of a domestic insurer, the state insurance commissioner will consider such factors as the financial strength of the acquirer, the integrity and management of the acquirer’s board of directors and executive officers, the acquirer’s plans for the future operations of the domestic insurer and any anti-competitive results that may arise from the consummation of the acquisition of control. Generally, state statutes provide that control over a domestic insurer is presumed to exist if any person, directly or indirectly, owns, controls, holds with the power to vote, or holds proxies representing, 10% or more of the voting securities of the domestic insurer. Because a person acquiring 10% or more of our common shares would indirectly control the same percentage of the stock of the AXIS U.S. Subsidiaries, the insurance change of control laws of Connecticut, Illinois and New York would likely apply to such a transaction.
The Insurance Act in Bermuda requires that where the shares of a registered insurer or reinsurer, or the shares of its parent, are traded on a recognized stock exchange, and a person becomes a 10%, 20%, 33% and 50% shareholder controller of that insurer or reinsurer, that person shall, within 45 days, notify the Bermuda Monetary Authority in writing that he has become a controller. In addition, a person who is a shareholder controller of a class 4 insurer or reinsurer (such as AXIS Specialty Bermuda) whose shares or shares of its parent company are traded on a recognized stock exchange must serve the Bermuda Monetary Authority with a notice in writing that he has reduced or disposed of his holding in the insurer or reinsurer where the proportion of voting rights in the insurer or reinsurer held by him will have reached or has fallen below 10%, 20%, 33% or 50% not later than 45 days after such disposal. A shareholder controller refers to a person who (i) holds 10% or more of the shares carrying rights to vote at a shareholders’ meeting of the registered insurer or reinsurer or its parent; (ii) is entitled to exercise 10% or more of the voting power at any shareholders meeting of the registered insurer or reinsurer or its parent; or (iii) is able to exercise significant influence over the management of the registered insurer or reinsurer or its parent by virtue of its entitlement to exercise, or control the exercise of, the voting at the shareholders’ meeting. The Bermuda Monetary Authority may object to any person who has become a shareholder at a specified level where it appears that such person is not, or is no longer, a fit and proper person to be a shareholder of the Bermuda registered insurance or reinsurance company.
In addition, the Insurance Acts and Regulations in Ireland require that anyone acquiring or disposing of a direct or indirect holding in an Irish authorized (re)insurance or reinsurance company (such as AXIS Specialty Europe or AXIS Re SE) that represents 10% or more of the capital or of the voting rights of such company or that makes it possible to exercise a significant influence over the management of such company, or anyone who proposes to decrease or increase that holding to specified levels, must first notify the CBICentral Bank of Ireland ("CBI") of their intention to do so. They also require any Irish authorized (re)insurance or reinsurance company that becomes aware of any acquisitions or disposals of its capital involving the specified levels to notify the CBI. The specified levels are 20%, 33% and 50% or such other level of ownership that results in the company becoming the acquirer’s subsidiary within the meaning of article 20 of the European Communities (non-Life Insurance) Framework Regulations 1994.
The CBI has three months from the date of submission of a notification within which to oppose the proposed transaction if the CBI is not satisfied as to the suitability of the acquirer in view of the necessity "to ensure prudent and sound management of the (re)insurance or reinsurance undertaking concerned." Any person owning 10% or more of the capital or voting rights or an amount that makes it possible to exercise a significant influence over the management of AXIS Capital would be considered to have a "qualifying holding" in AXIS Specialty Europe and AXIS Re SE.
TheIn the U.K., the Prudential Regulation Authority ("PRA") and the U.K. Financial Conduct Authority ("FCA") regulate the acquisition of "control" of any U.K. Insurance companies and Lloyd's managing agents which are authorized under the Financial Services and Markets Act 2000 ("FSMA"). Any legal entity or individual that (together with any person with whom it or he is "acting in concert") directly or indirectly acquires 10% or more of the shares in a U.K. authorized insurance company or Lloyd's managing agent, or their parent company, or is entitled to exercise or control the exercise of 10% or more of the voting power in such authorized insurance company or Lloyd's managing agent or their parent company, would be considered to have acquired "control" for the purposes of the relevant legislation, as would a person who had significant influence over the management of such authorized insurance company or their parent company by virtue of his shareholding or voting power in either. A purchase of 10% or more of the ordinary shares of the Company would therefore be considered to have acquired "control" of AXIS Managing Agency Limited and Novae Syndicates Limited.Ltd. Under FSMA, any person proposing to acquire "control" over a U.K. authorized insurance company must give prior notification to the PRA of his intention to do so. The PRS,PRA, which will consult with the FCA, would then have 60 working days to consider that person's


application to acquire "control" (although this 60 working day period can be extended by up to 30 additional working days in certain circumstances where the


regulators have questions relating to the application). Failure to make the relevant prior application could result in action being taken against AXIS Managing Agency Limited or Novae Syndicates LimitedLtd. by the PRA.
A person who is already deemed to have "control" will require prior approval of the PRA if such person increases their level of "control" beyond certain percentages. These percentages are 20%, 30% and 50%. Similar requirements apply in relation to the acquisition of control of a U.K. authorized person which is an insurance intermediary (such as NovaeAXIS Underwriting Limited or Contessa Limited) except that the approval must be obtained from the FCA rather than the PRA and the threshold triggering the requirement for prior approval is 20% of the shares or voting power in the insurance intermediary or its parent company. The approval of the Council of Lloyd's is also required in relation to the change of control of a Lloyd's managing agent or member. Broadly, Lloyd's applies the same tests in relation to control as are set out in the FSMA (see above) and in practice coordinates its approval process with that of the PRA.
While our bye-laws limit the voting power of any shareholder to less than 9.5%, there can be no assurance that the applicable regulatory body would agree that a shareholder who owned 10% or more of our shares did not, because of the limitation on the voting power of such shares, control the applicable Insurance Subsidiary. These laws may discourage potential acquisition proposals and may delay, deter or prevent a change of control of the Company, including transactions that some or all of our shareholders might consider to be desirable.
Anti-takeover provisions in our bye-laws could impede an attempt to replace our directors or to effect a change in control, which could diminish the value of our common shares.
Our bye-laws contain provisions that may make it more difficult for shareholders to replace directors and could delay or prevent a change of control that a shareholder might consider favorable. These provisions include a staggered board of directors, limitations on the ability of shareholders to remove directors other than for cause, limitations on voting rights and restrictions on transfer of our common shares. These provisions may prevent a shareholder from receiving the benefit from any premium over the market price of our shares offered by a bidder in a potential takeover. Even in the absence of an attempt to effect a change in management or a takeover attempt, these provisions may adversely affect the prevailing market price of our shares if they are viewed as discouraging takeover attempts in the future.
Risks Related to Taxation
We may become subject to taxes in Bermuda after March 31, 2035, which may have a material adverse effect on our results of operations.

The Bermuda Minister of Finance, under the Exempted Undertakings Tax Protection Act 1966 of Bermuda, as amended, has given each of our Bermuda resident companies an assurance that if any legislation is enacted in Bermuda that would impose tax computed on profits or income, or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, then the imposition of any such tax will not be applicable to our Bermuda resident companies or any of their respective operations, shares, debentures or other obligations until March 31, 2035. Given the limited duration of the Minister of Finance’s assurance, we cannot be certain that we will not be subject to any Bermuda tax after March 31, 2035.
Our non-U.S. companies may be subject to U.S. tax that may have a material adverse effect on our results of operations.

We intend to manage our business so that each of our non-U.S. companies, apart from our Lloyd's operations with U.S. effectively connected income, will operate in such a manner that none of these companies should be subject to U.S. tax (other than U.S. excise tax on (re)insurance premium incomeor reinsurance premiums attributable to insuring or reinsuring U.S. risks and U.S. withholding tax on some types of U.S. source investment income), because none of these companies should be treated as engaged in a trade or business within the U.S. However, because there is considerable uncertainty as to the activities that constitute being engaged in a trade or business within the U.S., we cannot be certain that the U.S. Internal Revenue Service will not contend successfully that any of itsour non-U.S. companies is/are engaged in a trade or business in the U.S. If any of our non-U.S. companies were considered to be engaged in a trade or business in the U.S., it could be subject to U.S. corporate income and additional branch profits taxes on the portion of its earnings effectively connected to such U.S. business. If this were to be the case, our results of operations could be materially adversely affected.



Our non-U.K. companies may be subject to U.K. tax that may have a material adverse effect on our results of operations.

We intend to operate in such a manner so that none of our non-U.K. companies should beare resident in the U.K. for tax purposes and that none of our non-U.K. resident companies, other than AXIS Specialty Europe and AXIS Specialty U.S. Services, Inc., should have a permanent establishment in the U.K. Accordingly, we expect that none of our non-U.K. resident companies, other than AXIS Specialty Europe and AXIS Specialty U.S. Services, Inc., should be subject to U.K. tax. Nevertheless, because neither case law nor U.K. statutes conclusively define the activities that constitute trading in the U.K. through a permanent establishment, the U.K. Inland Revenuetax authority might contend successfully that any of our non-U.K. companies, in addition to AXIS Specialty Europe and AXIS Specialty U.S. Services, Inc., is/are trading in the U.K. through a permanent establishment in the U.K. and therefore subject to U.K. tax.
In addition, there are circumstances in which companies that are neither resident in the U.K., nor entitled to the protection afforded by a double tax treaty between the U.K. and the jurisdiction in which they are resident, may be exposed to income tax in the U.K. (other than by deduction or withholding) on the profits of a trade carried on there even if that trade is not carried on through a permanent establishment. We intend to operate in such a manner that none of our companies will be subject to U.K. income tax in this respect.
If any of our non-U.K. resident companies other than AXIS Specialty Europe and AXIS Specialty U.S. Services, Inc., were treated as being resident in the U.K. for U.K. corporation tax purposes, or if any of our non-U.K. companies, other than AXIS Specialty Europe or AXIS Specialty U.S. Services, Inc., were to be treated as carrying on a trade in the U.K., whether or not through a permanent establishment, our results of operations could be materially adversely affected.
The U.K. diverted profits tax ("DPT") is separate from U.K. corporation tax and is charged at a higher rate. It is an anti-avoidance measure aimed at protecting the U.K. tax base against the artificial diversion of profits that are being earned by activities carried out in the U.K. but which are not otherwise being taxed in the U.K., in particular as a result of arrangements between companies in the same multinational group. The U.K. network of double tax treaties does not offer protection from a DPT charge. In the event that the rules apply to certain arrangements, upfront payment of the U.K. tax authority’s estimate of the deemed tax liability may be required. If any of our non-U.K. companies is liable to DPT, this could have a material adverse effect on our results.
Our U.K. operations may be affected by future changes in U.K. tax law.

AXIS Specialty Europe, AXIS Specialty U.S. Services, Inc. and our other U.K. resident companies should be treated as taxable in the U.K. Any change in the basis or rate of U.K. corporation tax could materially adversely affect the operations of these companies.
Our operations may be adversely affected by a transfer pricing adjustment in computing taxable profits.
Any affiliated arrangements between contracting parties established in different jurisdictions are subject to transfer pricing regimes. Consequently, if any arrangement (including any reinsurance or financing arrangements) is found not to be on arm’s length terms, an adjustment will be required to compute taxable profits as if the arrangement were on arm’s length terms. Any transfer pricing adjustment could adversely impact the tax charge suffered by the relevant tax-paying company.
With effect from January 1, 2016, Bermuda has implemented country by country reporting ("CBCR") whereby multinational groups are required to report details of their operations and intra-group transactions in each jurisdiction. It is possible that our approach to transfer pricing may become subject to greater scrutiny from the tax authorities in the jurisdictions in which we operate, which may lead to transfer pricing audits in the future.



Our non-Irish companies may be subject to Irish tax that may have a material adverse effect on our results of operations.

We intend to operate our non-Irish resident companies in such a manner so that none of our non-Irish resident companies should be resident in Ireland for tax purposes and that they should not be treated as carrying on a trade through a branch or agency in Ireland.
Accordingly, we expect that none of our non-Irish resident companies should be subject to Irish corporation tax. Nevertheless, since the determination as to whether a company is resident in Ireland is a question of fact to be determined based on a number of different factors and since neither case law nor Irish legislation conclusively defines the activities that constitute trading in Ireland through a branch or agency, the Irish Revenue Commissioners might contend successfully that any of our non-Irish companies is resident in or otherwise trading through a branch or agency in Ireland and therefore subject to Irish corporation tax. If this were the case, our results of operations could be materially adversely affected.
If corporate tax rates in Ireland increase, our results of operations could be materially adversely affected.

Trading income derived from the (re)insurance businessesand reinsurance business carried on in Ireland by AXIS Specialty Europe and AXIS Re SE is generally taxed in Ireland at a rate of 12.5%. Over the past number of years, various E.U. member states have, from time to time, called for harmonization of the corporate tax base within the E.U. Ireland, along with other member states, has consistently resisted any movement towards standardized corporate tax rates or tax base in the E.U. The Government of Ireland has also made clear its commitment to retain the 12.5% rate of corporation tax. If, however, tax laws in Ireland change so as to increase the general corporation tax rate in Ireland, our results of operations could be materially adversely affected.



If investments held by AXIS Specialty Europe SE or AXIS Re SE are determined not to be integral to the (re)insurance businessesand reinsurance business carried on by those companies, additional Irish tax could be imposed and our business and financial results could be materially adversely affected.

Based on administrative practice, taxable income derived from investments made by AXIS Specialty Europe and AXIS Re SE is generally taxed in Ireland at the rate of 12.5% on the grounds that such investments either form part of the permanent capital required by regulatory authorities, or are otherwise integral to the (re)insurance businessesand reinsurance business carried on by those companies. AXIS Specialty Europe and AXIS Re SE intend to operate in such a manner so that the level of investments held by such companies does not exceed the amount that is integral to the (re)insurance businessesand reinsurance business carried on by AXIS Specialty Europe and AXIS Re SE. If, however, investment income earned by AXIS Specialty Europe or AXIS Re SE is deemed to be non-trading income, Irish corporation tax could apply to such investment income at a higher rate (currently 25%) instead of the general 12.5% rate, and our results of operations could be materially adversely affected.

Changes in U.S. federal income tax law and other tax laws, including changes resulting from the recommendations of the Organization for Economic Cooperation and Development ("OECD"), could materially adversely affect us.

In the past, legislation has been introduced in the The 2017 Tax Cuts and Jobs Act ("U.S. CongressTax Reform"), which included certain provisions that were intended to eliminate some perceived tax advantages of companies (including (re)insurance and reinsurance companies) that have legal domiciles outside the U.S., but have certain U.S. connections. The recently enacted U.S. Tax Reform willconnections, significantly alteraltered existing U.S. federal domestic and international income tax law. Among other things, the U.S. Tax Reform reducesreduced the U.S. corporate tax rate, makesmade extensive changes to the international tax system, eliminateseliminated the corporate alternative minimum tax system, modifiesmodified the loss reserve discounting methodology, and changeschanged the proration percentage on tax-favored investments. Furthermore, under the U.S. Tax Reform, certain U.S. corporations that make deductible payments, including reinsurance premiums, to foreign affiliates in excess of certain amounts will now be required to pay a base erosion minimum tax. NewCurrently, there are only proposed regulations regarding the application of the base erosion minimum tax, and new regulations or pronouncements interpreting or clarifying U.S. federal income tax laws relating to (re)insurance and reinsurance companies may be forthcoming. We cannot be certain if, when, or in what form, such regulations or pronouncements may be provided, and whether such guidance will have a retroactive effect.







Changes in tax laws resulting from the recommendations of the Organization for Economic Corporation and Development ("OECD") could materially adversely affect us.
The OECD has published reports and launched a global initiative among member and non-member countries on measures to limit harmful tax competition, known as the "Base Erosion and Profit ShiftingShifting" ("BEPS") project.project and, in 2015, published reports containing a suite of recommended actions. These measures are largely directed at counteracting the effects of tax havenslow-tax and preferential tax regimes in countries around the world.world, including expanding the definition of permanent establishment and updating the rules for attributing profits to permanent establishments, tightening transfer pricing rules to ensure that outcomes are in line with value creation, neutralizing the effect of hybrid financial instruments and limiting the deductibility of interest costs for tax purposes and preventing double tax treaty abuse. We expect many countries to change their tax laws in response to thisthe BEPS project, and several countries have already changed or proposed changes to their tax laws in anticipationlaws. In particular, the E.U. has sought to harmonize the response of member states to the final reports.BEPS reports via the Anti-Tax Avoidance Directive ("the ATAD"). The ATAD requires all E.U. member states to apply certain specified anti-avoidance measures, including a controlled foreign companies regime and limitations on interest deductions. Changes to tax laws and additional reporting requirements could increase the tax burden and the complexity burden and cost of tax compliance.

Future changesOn May 31, 2019, the OECD published a "Programme of Work", designed to address the tax challenges created by an increasingly digitalized economy. This was divided into two pillars. Pillar One addresses the broader challenge of a digitalized economy and focuses on the allocation of group profits among taxing jurisdictions, based on a market-based concept rather than the historical "permanent establishment" concept. Pillar Two addresses the remaining BEPS risk of profit shifting to entities in current accounting practices may materially impact our reported financial results.

Future changes in accounting practices may result in significant additional expenseslow tax jurisdictions, by introducing a global minimum tax and may affecta proposed tax on base eroding payments, which would operate through a denial of a deduction or the calculationimposition of financial statement line items.  For example,source-based taxation (including withholding tax) on certain payments. The OECD would like for this could occur if we are requiredproposal to prepare information relatingbe agreed by the participating members by the end of 2020, and for it to prior periods or if we are required to apply new requirements retroactively.

The price of our common shares may be volatile.

Thereincorporated into local jurisdiction tax laws and treaties shortly thereafter. To date, the proposal has been significant volatility in the market for equity securities in recent years. During 2017, 2016,drawn broadly and 2015 the price of our common shares fluctuated fromcould have a low of $49.42 to a high of $71.06, a low of $51.01 to a high of $66.23 and a low of $47.65 to a high of $60.00, respectively. The price of our common shares may not remain at or exceed current levels. The following factors, in addition to those described in other risk factors above, may have anmaterial adverse impact on our operations and results.
Legislation enacted in Bermuda in response to the market priceEuropean Union’s review of our common stock:

actual or anticipated variations in our quarterly results, including as a result of catastrophes or our investment performance; 

any share repurchase program; 

changes in market valuation of companies in the insurance and reinsurance industry; 



changes in expectations of future financial performance or changes in estimates of securities analysts; 

fluctuations in stock market processes and volumes; 

issuances or sales of common shares or other securities in the future; 

the addition or departure of key personnel;

changes inharmful tax law; and

announcements by us or our competitors of acquisitions, investments or strategic alliances.

Stock markets in the U.S. continue to experience volatile price and volume fluctuations. Such fluctuations, as well as the general political situation, current economic conditions or interest rate or currency rate fluctuations,competition could adversely affect our operations and financial condition.
During 2017, the market priceEconomic and Financial Affairs Council released a list of non-cooperative jurisdictions for tax purposes. The stated aim of this list, and accompanying report, was to promote good governance worldwide in order to maximize efforts to prevent tax fraud and tax evasion. Bermuda was not on the list of non-cooperative jurisdictions, but did feature in the report (along with approximately 40 other jurisdictions) as having committed to address concerns relating to economic substance by December 31, 2018. In accordance with that commitment, Bermuda has enacted legislation that requires certain entities in Bermuda engaged in "relevant activities" to maintain a substantial economic presence in Bermuda and to satisfy economic substance requirements. The list of "relevant activities" includes carrying on as a business any one or more of: banking, insurance, fund management, financing, leasing, headquarters, shipping, distribution and service center, intellectual property and holding entities. Any entity that must satisfy economic substance requirements but fails to do so could face automatic disclosure to competent authorities, in each jurisdiction in which its owners or beneficial owners is incorporated, formed, registered or resident, of the information filed by the entity with the Bermuda Registrar of Companies in connection with the economic substance requirements and may also face financial penalties, restriction or regulation of its business activities and/or may be struck off as a registered entity in Bermuda.
At present, the impact of these new economic substance requirements is unclear, and it is not possible to accurately predict the effect of these requirements on us and our stock.business. The requirements may increase the complexity and costs of carrying on our business and could adversely affect our operations and financial condition.

Effective July 1, 2017, our reinsurance segment no longer writes derivative-based risk management products which address weather risks.

On July 5, 2017, we announced that we agreed on the terms of a recommended offer to acquire Novae, a diversified specialty (re)insurer that operates through Syndicate 2007 at Lloyd’s. On October 2, 2017 ("the acquisition date), we acquired a 100% ownership interest in Novae. The results of Novae are included in the results of the our insurance and reinsurance segments


from this date. On October 6, 2017, we received clearance from all applicable regulators, including the European Commission, and commenced management control and integration of the combined businesses from this date.

On July 6, 2017, S&P Global Ratings affirmed its 'A-' long-term counterparty credit and senior debt ratings of AXIS Capital, and its 'A+' long-term counterparty credit and financial strength ratings of the Company's core operating subsidiaries. At the same time, S&P Global Ratings revised its outlook on AXIS Capital to negative from stable based on the planned acquisition of Novae.

On July 14, 2017, we announced that we had received final authorization from Lloyd's, the Prudential Regulation Authority ("PRA") and the Financial Conduct Authority ("FCA") for our own Lloyd's managing agent, AXIS Managing Agency Limited ("AXIS Managing Agency"). Effective August 4, 2017, AXIS Managing Agency assumed management of Syndicate 1686 at Lloyd's, replacing our third-party managing agency agreement with Asta Managing Agency Limited, which had been in place since 2014.

On December 6, 2017, we issued $350 million aggregate principal amount of 4.0% senior unsecured notes (the "4.0% Senior Notes") which will mature on December 6, 2027. We used a portion of the proceeds from the issuance of 4.0% Senior Notes to repay a Novae term loan of $67 million and intends to use a further portion of the proceeds from the issuance of 4.0% Senior Notes to repay or redeem its 2.650% Senior Notes which are due on April 1, 2019.

On January 8, 2018, we announced that we had received authorization from Lloyd’s for AXIS Managing Agency Ltd to commence management and oversight of Syndicate 2007 and Special Purpose Arrangement 6129 )"SPA 6129") with effect from January 1, 2018. The authorization creates a single managing agent structure for our operations at Lloyd’s. Syndicate 2007 and SPA 6129 will operate alongside Syndicate 1686, which AXIS Managing Agency currently manages. We have initiated plans to consolidate its Lloyd’s business into Syndicate 1686, under management of AXIS Managing Agency, and anticipates completing that process by January 1, 2019.

On January 1, 2018, AXIS Managing Agency, entered into an agreement for the Reinsurance to Close ("RITC") of the 2015 and prior years of account of Syndicate 2007. This RITC transaction covers the net reserve for losses and loss expenses associated with all business underwritten by Novae Group plc ("Novae") in the 2015 and prior years. The transaction resulted in a positive financial impact, which was reflected in the fair values of Novae's assets acquired and liabilities assumed on the acquisition date.

On January 23, 2018, we announced that we plan to realign our accident and health line of business during the first quarter of 2018. This business is currently included in our insurance segment. As a result of the realignment, this business will also be included in our reinsurance segment.

On February 16, 2018, A.M. Best Company, Inc. ("A.M. Best") affirmed the Long-Term ICR of 'a-' and the existing Long-Term Issue Credit Ratings (Long-Term IR) of AXIS Capital and the Financial Strength Rating of A+ (Superior) and the Long-Term Issuer Credit Ratings ("Long-Term ICR") of "aa-" of our core operating subsidiaries. At the same time, A.M. Best revised its outlook to negative from stable based on unfavorable trends in the Group’s operating performance, particularly from our insurance segment.
Outlook


We are committed to being a leader in specialty risk, an area in whichinsurance and global reinsurance markets; areas where we already have depth of talent and experience,expertise. As a mid-sized player that is both sophisticated and have earnedagile, we believe we are well-positioned to succeed in a rapidly evolving industry. Across our business, we continue to emphasize underwriting discipline to actively manage our portfolio. In 2020, we are focused on further growing our most attractive lines to drive an outstanding reputation. Committedimproved risk-adjusted return for our shareholders.
In the insurance market, rates and terms and conditions across most lines generally continued to see accelerating improvement. We are well-positioned in the markets that are seeing the strongest pricing actions, including Lloyd’s, U.S. E&S and Professional Lines, and we expect more business will meet our hybrid strategy, we have developed substantial platformsreturn adequacy hurdles in both insurance and reinsurance, providing us with balance and diversification. Management believes its positioning, franchise, expert underwriters and strong relationships with distributors and clients will providethe coming year. We continue to pursue opportunities for further profitable growth in 2018, with variances amongst our lines driven by our tactical response tothe businesses where we have expertise and existing leadership positions.
In the reinsurance market, conditions. At the same time, we are broadeningseeing variability in pricing across specific lines and geographies.  In quota share business, we benefit from improvements in the primary markets. In excess of loss treaties, we observe pricing generally responding to recent loss trends. This remains a competitive market, and at the 1/1/20 renewals, our risk-funding sources and developing vehicles that utilize the industry’s available third party capital. Consequently,aggregate estimated premium on renewed treaties was lower than aggregate premiums on expiring treaties. Looking forward, we expect that our net premiums written will not grow as much as our gross premiums written, as we intend to share more of our risk with strategic capital partners.
The insurance market has begun to respond tomeaningful rate increases at the cumulative effects of many years of price deterioration and the record significant catastrophe activity incurred in 2017. Market conditions and rates across most lines have generally improved, with catastrophe exposed property lines experiencing the most upward rate momentum. While market conditions have improved they will likely remain variable through the year and possibly beyond as carriers assess pricing, portfolio construction and account preferences. In this competitive market environment with mixed market conditions, we are focusing on lines of business and market segments that are adequately priced. In addition, our acquisition of Novae increases our scale and


relevance in the London marketplace,Japanese Catastrophe renewal period (April), and we will be pushing for increases in Florida Catastrophe (June), and US Casualty business (April-October) in 2020. We expect toour reinsurance premium volume in these renewals will be well-positioned to capitalizedependent on new opportunities and benefit from improved market conditions emerging through the international specialty insurance market, including Lloyd'sour view of London.achievable rate adequacy.
The reinsurance market is experiencing some upward movement in price after the substantial loss activity that occurred in 2017. These increases, both in catastrophe and other lines of business, are necessary to improve adequacy of rates and vary across geographies. The market overall is strongly capitalized and demand side conditions, while largely stable, do present opportunities to support clients in a world of changing exposures, regulation, and reinsurance panels. We also believe that there is a real opportunity to achieve more leadership and scale, emphasizing our clients and new streams of income in the future while still defending the quality of our existing portfolio. We are also focused on managing the volatility of our portfolio and expanding our already strong group of strategic capital partners.
Non-GAAP Financial Measures
We present our results of operations in athe way we believe will be most meaningful and useful to investors, analysts, rating agencies and others who use our financial information to evaluate our performance. Some of the measurements we use are considered non-GAAP financial measures under SEC rules and regulations. In this Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A"), we present underwriting-related general and administrative expenses, consolidated underwriting income non-GAAP(loss), operating income (in(loss) (in total and on a per share basis)basis), operating return on average common equity ("operating ROACE"), amounts presented on a constant currency basis, and pre-tax total return on cash and investments excluding foreign exchange movements, ex-PGAAP operating income (loss) (in total and on a per share basis) and ex-PGAAP operating ROACE which are non-GAAP financial measures as defined in Item 10(e) of SEC Regulation S-K. We believe that these non-GAAP financial measures, which may be defined and calculated differently by other companies, better explain and enhance the understanding of our results of operations. However, these measures should not be viewed as a substitute for those determined in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP.

GAAP").
Underwriting-Related General and Administrative Expenses
Underwriting-related general and administrative expenses include those general and administrative expenses that are incremental and/or directly attributable to our individual underwriting operations. While this financial measure is presented in Item 8, Note 43 to the Consolidated Financial Statements 'Segment Information', it is considered a non-GAAP financial measure when presented elsewhere on a consolidated basis.

Corporate expenses include holding company costs necessary to support our worldwide insurance and reinsurance operations and costs associated with operating as a publicly-traded company. As these costs are not incremental and/or directly attributable to our individual underwriting operations, we exclude themthese costs are excluded from underwriting-related general and administrative expenses, and therefore, consolidated underwriting income.income (loss). General and administrative expenses, the most comparable GAAP financial measure to underwriting-related general and administrative expenses, also includes corporate expenses.

The reconciliation of underwriting-related general and administrative expenses to general and administrative expenses, the most comparable GAAP financial measure, is presented in the 'Results'Management's Discussion and Analysis of Financial Condition and Results of Operations – Executive Summary – Results of Operations'.


Consolidated Underwriting Income (Loss)
Consolidated underwriting income (loss) is a pre-tax measure of underwriting profitability that takes into account net premiums earned and other insurance related income (losses) as revenues and net losses and loss expenses, acquisition costs and underwriting-related general and administrative costsexpenses as expenses. While this measure is presented in Item 8, Note 4 3


to the Consolidated Financial Statements 'Segment Information', it is considered a non-GAAP financial measure when presented elsewhere on a consolidated basis.


We evaluate our underwriting results separately from the performance of our investment portfolio. As such, we believe it is appropriate to exclude net investment income and net realized investment gains (losses) from our underwriting profitability measure.


Foreign exchange losses (gains) in our Consolidated Statementconsolidated statements of Operationsoperations primarily relate to the impact of foreign exchange rate movements on our net insurance-related liabilities. However, we manage our investment portfolio in such a way that unrealized and realized foreign exchange losses (gains) on our investment portfolio generally offset a large portion of the foreign exchange losses (gains) arising from our underwriting portfolio. As a result, we believe that foreign exchange losses (gains) are not a meaningful contributor to our underwriting performance, therefore, foreign exchange losses (gains) are excluded from consolidated underwriting income.income (loss).




Interest expense and financing costs primarily relate to interest payable on our senior notes.debt. As these costsexpenses are not incremental and/or directly attributable to our individual underwriting operations, we exclude themthese expenses are excluded from underwriting-related general and administrative expenses, and therefore, consolidated underwriting income.income (loss).

The bargain purchase gain, recognized upon the acquisition of Aviabel, reflects the excess of the fair value of the net identifiable assets acquired over the fair value of consideration transferred, and is not related to the underwriting process, therefore it is excluded from consolidated underwriting income.


Transaction and reorganization expenses are primarily driven by business decisions, the nature and timing of which are not related to the underwriting process, therefore, these expenses are excluded from consolidated underwriting income.income (loss).

Loss on repurchase of preferred shares arose from capital transactions that are not reflective of underlying business performance, therefore, this expense is excluded from consolidated underwriting income.


Amortization of intangiblesintangible assets including VOBA arose from business decisions, the nature and timing of which are not related to the underwriting process, therefore, these expenses are excluded from consolidated underwriting income.income (loss).


The revaluationBargain purchase gain, recognized on the acquisition of net deferred tax assetCompagnie Belge d'Assurances Aviation NV/SA ("DTA"Aviabel") resulted in a tax expense recognized in, reflects the fourth quarter of 2017 related to the revaluation of our net DTA, due to the reduction in the U.S. corporate income tax rate from 35% to 21% enacted as partexcess of the U.S. Tax Reform. The nature and timingfair value of the tax expense associated withnet identifiable assets acquired over the U.S. Tax Reformfair value of consideration transferred and is not related to the underwriting process,indicative of future revenues, therefore, this expenserevenue is excluded from consolidated underwriting income.income (loss).


The termination fee received represents the break-up fee received on the cancellation of the Amalgamation Agreement
between PartnerRe Ltd. and the Company and is not related to the underwriting process, therefore it is excluded from consolidated underwriting income.
We believe that presentation of underwriting-related general and administrative expenses and consolidated underwriting income (loss) provides investors with an enhanced understanding of our results of operations, by highlighting the underlying pre-tax profitability of our underwriting activities. The reconciliation of consolidated underwriting income (loss) to income before income taxes and interest innet income (loss) of equity method investments,, the most comparable GAAP financial measure, is presented in the 'Results'Management's Discussion and Analysis of Financial Condition and Results of Operations – Executive Summary – Results of Operations'.
Non-GAAP Operating Income (Loss)
Non-GAAP operatingOperating income (loss) represents after-tax operational results without considerationexclusive of after-tax net realized investment gains (losses), foreign exchange losses (gains), transaction and reorganization expenses, interest in income (loss) of equity method investments, revaluation of net deferred tax asset and bargain purchase gain, transaction and reorganization expenses, loss on repurchase of preferred shares, and termination fee received.gain.
Although the investment of premiums to generate income and realized investment gains (losses) is an integral part of our operations, the determination to realize investment gains (losses) is independent of the underwriting process and is heavily influenced by the availability of market opportunities. Furthermore, many users believe that the timing of the realization of investment gains (losses) is somewhat opportunistic for many companies.
Foreign exchange losses (gains) in our Consolidated Statementsconsolidated statements of Operations areoperations primarily driven byrelate to the impact of foreign exchange rate movements on net insurance related-liabilities. However, this movement is only one element of the overall impact of foreign exchange rate fluctuations on our financial position.insurance-related liabilities. In addition, we recognize unrealized foreign exchange losses (gains) on our available-for-sale investments in other comprehensive incomeequity securities and foreign exchange losses (gains) realized uponon the sale of theseour available for sale investments and equity securities in net investment gains (losses). We also recognize unrealized foreign exchange losses (gains) on our available for sale investments in net realized investments gains (losses)other comprehensive income (loss). These unrealized and realized foreign exchange rate movementslosses (gains) generally offset a large portion of the foreign exchange losses (gains) reported separately in net income (loss), available (attributable) to common shareholders, thereby minimizing the impact of foreign exchange rate movements on total shareholders’ equity. As such,a result, the foreign exchange losses (gains) in our Statementsconsolidated statements of Operationsoperations in isolation are not a fair representation of the performance of our business.


Transaction and reorganization expenses are primarily driven by business decisions, the nature and timing of which are not related to the underwriting process, therefore, these expenses are excluded from operating income (loss).

Interest in income (loss) of equity method investments is primarily driven by business decisions, the nature and timing
of which are not related to the underwriting process, therefore, this income (loss) is excluded from operating income
(loss).



The revaluation of net deferred tax asset resulted inrepresents a tax expense recognized in the fourth quarter of 2017 related to the revaluation of our net DTA,deferred tax asset, due to the reduction in the U.S. corporate income tax rate from 35% to 21% enacted as part of the Tax Cuts and Jobs Act of 2017 ("U.S. Tax Reform.Reform"). The nature and timing of the tax expense associated with the U.S. Tax Reform is not related to the underwriting process, andtherefore, this expense is not representative of underlying business performance.excluded from operating income (loss).

Transaction and reorganization expenses are primarily driven by business decisions, the nature and timing of which are not related to the underwriting process and are not representative of underlying business performance.

Loss on repurchase of preferred shares arose from capital transactions that are not reflective of underlying business performance.

The termination fee received represents the break-up fee paid by PartnerRe Ltd. following the cancellation of the Amalgamation Agreement with the Company and is not indicative of future revenues.


Certain users of our financial statements evaluate performance excludingexclusive of after-tax net realized investment gains (losses), foreign exchange losses (gains), revaluation of deferred tax asset, bargain purchase gain, transaction and reorganization expenses, interest in income (loss) of equity method investments, revaluation of net deferred tax asset and losses on repurchase of preferred sharesbargain purchase gain to understand the profitability of recurring sources of incomeincome.
We believe that showing net income (loss) available (attributable) to common shareholders exclusive of after-tax net realized investment gains (losses), foreign exchange losses (gains), revaluation of deferred tax asset, bargain purchase gain, transaction and reorganization expenses, interest in income (loss) of equity method investments, revaluation of net deferred tax asset and losses on repurchase of preferred sharesbargain purchase gain reflects the underlying fundamentals of our business. In addition, we believe that this presentation enables investors and other users of our financial information to analyze performance in a manner similar to how our management analyzes the underlying business performance. We also believe this measure follows industry practice and, therefore, facilitates comparison of our performance with our peer group. We believe that equity analysts and certain rating agencies that follow us, and the insurance industry as a whole, generally exclude these items from their analyses for the same reasons. The reconciliation of non-GAAP operating income (loss) to net income available to shareholders,(loss), the most comparable GAAP financial measure, is presented in the 'Results'Management's Discussion and Analysis of Financial Condition and Results of Operations – Executive Summary – Results of Operations'.


We also present operating income (loss) per diluted common share and operating ROACE, which are derived from the operating income (loss) measure and are reconciled to the most comparable GAAP financial measures, earnings (loss) per diluted common share and return on average common equity ("ROACE"), respectively, in 'Management’s Discussion and Analysis of Financial Condition and Results of Operations – Executive Summary – Results of Operations'.

Constant Currency Basis


We present gross premiums written, net premiums written and net premiums earned on a constant currency basis in this MD&A. The amounts presented on a constant currency basis are calculated by applying the average foreign exchange rate from the current year to the prior year amounts. We believe this presentation enables investors and other users of our financial information to analyze growth in gross premiums written, net premiums written and net premiums earned on a constant basis. The reconciliation to gross premiums written, net premiums written and net premiums earned on a GAAP basis is presented in the 'GroupManagement’s Discussion and Analysis of Financial Condition and Results of Operations – Underwriting Results' section of this MD&A.Results – Consolidated'.


Pre-Tax Total Return on Cash and Investments excluding Foreign Exchange MovementMovements


Pre-tax total return on cash and investments excluding foreign exchange movements measures net investment income (loss), net realized investments gains (losses), interest in income (loss) of equity method investments, and pre-tax change in unrealized investment gains (losses) generated by our average cash and investment balances. The reconciliation of pre-tax total return on cash and investments excluding foreign exchange movements to pre-tax total return on cash and investments, the most comparable GAAP financial measure, is presented in the 'Management’s Discussion and Analysis of Financial Condition and Results of Operations – Net Investment Income and Net Realized Investment Gains (Losses)' section of this MD&A.. We believe this presentation enables investors and other users of our financial information to analyze the performance of our investments.investment portfolio.




Ex-PGAAP Operating Income (Loss)

Ex-PGAAP operating income (loss) represents operating income (loss) exclusive of amortization of VOBA and intangible assets, net of tax and amortization of acquisition costs, net of tax associated with Novae's balance sheet at October 2, 2017 (the "closing date" or "acquisition date"). The reconciliation of ex-PGAAP operating income (loss) to net income (loss) available (attributable) to common shareholders, the most comparable GAAP financial measure, is presented in 'Management’s Discussion and Analysis of Financial Condition and Results of Operations – Executive Summary – Results of Operations'.

We also present ex-PGAAP operating income (loss) per diluted common share and ex-PGAAP operating ROACE, which are derived from the ex-PGAAP operating income (loss) measure and are reconciled to the most comparable GAAP financial measures, earnings (loss) per diluted common share and ROACE, respectively, in 'Management’s Discussion and Analysis of Financial Condition and Results of Operations – Executive Summary – Results of Operations'.

We believe the presentation of ex-PGAAP operating income (loss), ex-PGAAP operating income (loss) per diluted common share and ex-PGAAP operating ROACE enables investors and other users of our financial information to better analyze the performance of our business.

Acquisition of Novae

On October 2, 2017, we acquired Novae. At the acquisition date, we identified VOBA, which represents the present value of the expected underwriting profit within policies that were in-force at the closing date of the transaction. In addition, the allocation of the acquisition price to the assets acquired and liabilities assumed based on estimated fair values at the acquisition date, resulted in the write-off of the deferred acquisition cost asset on Novae's balance sheet at the acquisition date as the value of policies in-force on that date are considered within VOBA. Consequently, underwriting income (loss) in 2019 and 2018 included the recognition of premiums attributable to Novae's balance sheet at the acquisition date without the recognition of the associated acquisition costs.

In addition, net investment income increased by $13 million in 2017 compared to 2016, attributable to contributions from fixed income following the acquisition of Novae and Aviabel. Comparatively, net investment income increased by $26 million in 2016, compared to 2015, primarily attributable to contributions from fixed income as a result of longer duration assets and income from commercial mortgage loans as a result of an increased allocation to this asset class in 2016.
Net Realized Investment Gains (Losses)
During 2017, net realized investment gains were $28 million compared to net realized investment losses of $61 million in 2016 and net realized investment losses of $138 million in 2015.

The financial results for 2017 resulted in a tax benefit of $8 million primarily attributable to the geographic distribution of income with the benefit being driven by losses in our U.S. and U.K. operations, largely offset by a tax charge of $42 million related to the revaluation of net deferred tax assets associated with the reduction in the U.S. corporate income tax rate from 35% to 21% enacted as part of the U.S. Tax Reform.
The tax expense recognized in 2016 increased to $6 million from $3 million in 2015. The increase was driven primarily by an increase in comparative European pre-tax income, offset partially by a decrease in comparative pre-tax income in the U.S.


Interest expense and financing costs were $68 million in 2017, 2016,2019 compared to $67 million in 2018. The increase of $1 million was due to the issuance of 3.900% senior unsecured notes ("3.900% Senior Notes") on June 19, 2019, and 2015 arethe issuance of 4.900% fixed-rate reset junior subordinated notes ("Junior Subordinated Notes") on December 10, 2019, partially offset by the repayment of the 2.65% senior unsecured notes ("2.65% Senior Notes") on April 1, 2019 and the repayment of the Dekania Notes on November 15, 2018.

The financial results for 2019 resulted in a tax expense of $24 million compared to a tax benefit of $29 million in 2018.

The tax expense of $24 million in 2019 was principally due to the generation of pre-tax income in our U.S. and European operations, partially offset by pre-tax losses in our U.K. operations.

The tax benefit of $29 million in 2018 was principally due to the generation of pre-tax losses in our U.K. and European operations, partially offset by income in our U.S. operations.
Reorganization Expenses
Reorganization expenses were $37 million in 2019 compared to $67 million in 2018, related to interest due on our senior notes, as well as interest due on Dekania Notes issued by Novaethe transformation program which was launched in 2017. Interest expense and financing costs increased by $4 million in 2017 compared to 2016, primarily attributable to costs associated with the Dekania Notes. Interest expense and financing costs in 2016 were consistent with 2015 as there were no significant changes to our debt and financing arrangements.

Bargain Purchase Gain

On April 1, 2017, we acquired general aviation insurer and reinsurer, Aviabel. The purchase price was allocated to the assets acquired and liabilities assumed of Aviabel based on estimated fair values on the closing date and a bargain purchase gain of $15 million was recognized.

Transaction and Reorganization Expenses

In connection with the acquisition of Novae, we incurred transaction and integration related expenses of $27 million including due diligence, legal, accounting, investment banking fees and expenses, as well as integration expenses related toThis program encompasses the integration of Novae intowhich commenced in the fourth quarter of 2017, the realignment of our operationsaccident and compensation-related costs associatedhealth business, together with the termination of certain employees.

We expectother initiatives designed to achieve run-rate cost savings of approximately $60 million on the combined 2016 expense base by 2020. We expect that approximately $30 to $35 million of these cost savings will be realized in 2018, increasing to $50 to $55 million in


2019, with the balance of these cost savings to be realized in 2020. These expense savings will be achieved through an increased focus on key underwriting product growth areas, the elimination of duplicate corporate roles, leveraging AXIS Capital's technology platformsincrease efficiency and the rationalization of third party contracts and professional fees. We expect to incur additional integration costs in 2018 through 2020 to achieve the cost savings.enhance profitability, while delivering a customer-centric operating model. These expenses willwere not be included in non-GAAP operating income.

Return on equityAverage Common Equity
Our objective is to generate superior returns on capital that appropriately reward our common shareholders for the risks we assume and to grow revenue only when we expect the returns will meet or exceed our requirements. We recognize that the nature of underwriting cycles and the frequency or severity of large loss events in any one year may challenge the ability to achieve a profitability target in any specific period, therefore our goal is to achieve top-quintile industry non-GAAP operating ROACE and growth in book value per share adjusted for dividends, with volatility consistent with the industry average.period.
ROACE reflects the impact of net income attributable(loss) available (attributable) to common shareholders including net realized investment gains (losses), foreign exchange losses (gains), revaluationreorganization expenses, and interest in income (loss) of net deferred tax assets, a bargain purchase gain relatedequity method investments.
ROACE increased in 2019 compared to 2018, primarily attributable to the acquisitioninvestment gains in the year, and a decrease in amortization of Aviabel, together with transaction and reorganization expensesVOBA associated with the acquisition of Novae, in 2017 as well as profitability enhancement initiatives in 2015 and loss on repurchase of preferred shares.
ROACE decreased in 2017, compared to 2016 primarily driven by the underwriting loss generated and foreign exchange losses in 2017 compared to underwriting income generated and foreign exchange gains in 2016. Transaction and reorganization expenses, together with amortization of value of business acquired and intangible assets associated with the acquisition of Novae incurred in 2017, also contributed to the decrease in ROACE.

Book Value per Diluted Common Share
We consider book value per common share
We consider diluted book value per common share to be an appropriate measure of our returns to common shareholders, as we believe growth in our book value on a diluted basis will ultimately translate into appreciation of our stock price.
During 2017 our dilutedIn 2019, book value per diluted common share decreasedincreased by 8%12%, driven primarily by the net loss available to common shareholders of $416 million and common dividends declared. In 2016 our diluted book value per common share appreciated 8%, driven by net income available to common shareholders of $465 million,generated and net unrealized investment gains reported in other comprehensive income, partially offset by common dividends declared.
In 2017 unrealized investment gains, and in 2016 a decrease in unrealized investment losses, which are included in accumulated other comprehensive income, also contributed to the growth in diluted book value per share.
The net unrealized investment gains in 20172019 reflected a decrease in interest rates and a tightening of credit spreads and the strengthening of the euro and pound sterling against the U.S. dollar which positively impacted the market values of non-U.S. government debtfixed maturities.
In 2018, book value per diluted common share decreased by 7%, primarily driven by an increase in net unrealized investment losses reported in other comprehensive income and corporate debt securities.common dividends declared.

This increase in multi-year contracts increased the amount of premium recorded in 2016 relating to future years compared to 2015. The increase in gross premiums written was partially offset by foreign exchange movements as the strengthening of the U.S. dollar drove comparative premium decreases in treaties denominated in foreign currencies. After adjusting for the impact of the multi-year contracts and foreign exchange movement, gross premiums written increased by $171 million.

After adjusting for the impact of the catastrophe and weather-related losses, our current accident year loss ratio increased to 63.7% in 2017 from 61.8% in 2016. The increase in the current accident year loss ratio after adjusting for the impact of the catastrophe and weather-related losses was driven elevated loss experiencedecreased to 60.6% in our insurance and reinsurance property lines, together with the impact of the Ogden Rate change on our reinsurance motor lines, and adverse impact of the rate and trend, partially offset by favorable changes2019 from 61.7% in business mix in our accident and health lines.
2016 versus 2015: The current accident year loss ratio increased to 67.4% in 2016 from 65.6% in 2015. The increase was primarily due to an increase in catastrophe and weather-related losses. During 2016 we incurred pre-tax catastrophe and weather-related net losses (net of reinstatement premiums) of $204 million or 5.6 points, attributable to U.S. weather-related events, Hurricane Matthew, Fort McMurray wildfires, the Japanese, Ecuadorian and South Island earthquakes, North Calgary hailstorm and European floods. Comparatively, in 2015 we incurred $100 million or 2.7 points of losses attributable to catastrophe and weather-related events.
After adjusting for the impact of the catastrophe and weather-related losses, our current accident year loss ratio decreased from 62.9% in 2015 to 63.7% in 2016.2018. The decrease in the current accident year loss ratio after adjusting for the impact of the catastrophe and weather-related losses was driven by a decrease in mid-size loss experience in our insurance marine and property lines and a decrease in loss experience in our reinsurance credit and surety lines, partially offset byprincipally due to the ongoing adverse impact of rateimproved pricing over loss trends and trend, and an increasechanges in loss experience in our insurance credit and political risk and reinsurance agriculture lines.business mix.

Estimates for Significant Catastrophe Events:
OurAt December 31, 20172019, net reserve for losses and loss expenses includesincluded estimated amounts for numerous catastrophe events. We caution that the magnitude and/or complexity of losses arising from these events, in particular Japanese Typhoons Hagibis, Faxai and Tapah, Hurricane Dorian, and the Australia Wildfires which occurred in 2019 together with Hurricanes Michael and Florence, California Wildfires and Typhoon Jebi which occurred in 2018 as well as Hurricanes Harvey, Irma and Maria the two earthquakes in Mexico and the wildfires in Northern and Southern California Wildfires which occurred in 2017 inherently increase the level of uncertainty and, therefore, the level of management judgment involved in arriving at our estimated net reserve for losses and loss expenses. As a result, our actual losses for these events may ultimately differ materially from our current estimates.


Our estimatedEstimated net reserve for losses and loss expenses in relation to the catastrophe events described above were derived from ground-up assessments of our in-force contracts and treaties providing coverage in the affected regions. These assessments take into account the latest information available from clients, brokers and loss adjusters. In addition, we consider industry insured loss estimates, market share analyses and catastrophe modeling analyses, when appropriate. Our estimates remainEstimates are subject to change as additional loss data becomes available.


We continue to monitor paid and incurred loss development for catastrophe events of prior years and update our estimates of ultimate losses accordingly.

Overview
Short-tail business
Our short-tailShort-tail business includes the underlying exposures in ourthe property and other, marine, and aviation reserve classes within ourin the insurance segment, and the underlying exposures in the property and other reserve class within ourin the reinsurance segment.
Development from theseThese reserve classes contributed $60recognized net adverse prior year reserve development of $85 million $148in 2019 including net adverse prior year reserve development of $133 million recognized by the reinsurance property and $152 million ofother reserve class, partially offset by net favorable prior year reserve development of $33 million contributed by the insurance marine reserve class and net favorable prior year reserve development of $11 million contributed by the insurance property and other reserve class.
The net adverse prior year reserve development of $133 million recognized by the reinsurance property and other reserve class was due to an increase in 2017, 2016loss estimates attributable to Hurricanes Irma and 2015, respectively,Michael consistent with industry trends, an increase in loss estimates attributable Typhoon Jebi consistent with updated industry insured loss estimates, and primarily reflectedreserve strengthening within the recognitionU.S. regional and commercial proportional property books of business and the European proportional property book of business.
These reserve classes contributed net favorable prior year reserve development of $86 million in 2018 reflecting overall better than expected loss emergence on these years.related to the 2017 catastrophe events.
Medium-tail business
Our medium-tailMedium-tail business consists primarily of insurance and reinsurance professional lines reserve classes, insurance credit and political risk insurance reserve class and reinsurance credit and surety reinsurance reserve class.
Our reinsuranceInsurance professional lines reserve class recognized $44 million, $30 million and $38 million ofrecorded net favorable prior year reserve development of $12 million and $32 million in 2017, 20162019 and 2015, respectively. The net favorable prior year loss development on this reserve class continued to reflect the2018, respectively, reflecting generally favorable experience on earlierolder accident years as we continued to transition to more experience based actuarial methods. As our loss experience on these accident years has generally been better than expected, this resulted in the recognition of net favorable prior year reserve development.
Our insuranceReinsurance professional reserve class recorded net favorable prior year development of $26 million in 2017 reflecting the generally favorable experience on earlier accident years as we transition to more experience based methods. As our loss experience has generally been better than expected, this resulted in the recognition of net favorable prior year reserve development. Our insurance professionallines reserve class recorded net favorable prior year reserve development of $14$21 million in 2016, also driven by overall better than expected development. Our insurance professional2018 reflecting generally favorable experience on older accident years as we continued to transition to more experience based actuarial methods.
Insurance credit and political risk reserve class recorded adversenet favorable prior year reserve development of $14$19 million in 2015 due to reserve strengthening on our Australian book of business during the three months ended September 30, 2015.2019 reflecting generally better than expected loss emergence.
Our reinsuranceReinsurance credit and surety reserve class recorded net favorable prior year reserve development of $53 million and $33 million $10 millionin 2019 and $27 million in 2017, 2016 and 2015,2018, respectively, due to the recognition ofreflecting generally better than expected loss emergence.
Our credit and political risk reserve class recorded net adverse development of $15 million in 2015 primarily relating to an increase in loss estimates for one specific claim.
Long-tail business
Ourlong-tailLong-tail business consists primarily of insurance and reinsurance liability reserve classes and reinsurance motor reserve classes.class.
Insurance liability reserve class recognized net adverse prior year reserve development of $25 million and $22 million in 2019 and 2018, respectively. The net adverse prior year reserve development in 2019 was primarily related to reserve strengthening within the U.S. excess casualty and U.S. primary casualty books of business. The net adverse prior year reserve development in 2018 was primarily related to reserve strengthening within the U.S. excess casualty book of business.



Our motorReinsurance liability reserve classes contributedclass recognized net favorable prior year reserve development of $1 million, $55$31 million and $37$23 million in 2017, 20162019 and 2015,2018, respectively. The net favorable prior year reserve development in 2019 and 2018 was due to progressively increased weight given by management to experience based indications on theolder accident years.
Reinsurance motor reserve class in 2016 and 2015 related to favorable loss emergence trends on several classes of business spanning multiple accident years. Netrecognized net favorable prior year reserve development of $71 million and $23 million in 2019 and 2018, respectively. The net favorable prior year reserve development in 20172019 was impacted by the U.K. Ministry of Justice’s announcement of a decreaseincrease in the Ogden discount rate and changes in related actuarial assumptions. The Ogden Rate which is used to calculate lump sum awards in U.K. bodily injury cases, known as the Ogden Rate. Effective March 20, 2017, the Ogden Rate changed from plus 2.5%minus 0.75% to minus 0.75%.
Our reinsurance liability reserve classes contributed net favorable prior year reserve development of $43 million, $44 million and $46 million, in 2017, 2016 and 2015, respectively.0.25%, effective August 5, 2019. The net favorable prior year reserve development in 2018 was primarily reflected the progressively increased weight given by managementattributable to the generally favorable emerging loss experiencenon proportional treaty business on earlierolder accident years.
This net favorable prior year development was partially offset by net adverse prior year development in our insurance liability reserve class of $8 million, $8 million and $27 million in 2017, 2016 and 2015, respectively, primarily related to reserve strengthening within our excess casualty book. In particular, the adverse development during 2015 was mainly driven by a higher frequency of large auto liability claims.
At the acquisition date, the fair value of reserves for losses and loss expenses for Syndicate 2007 was established giving weight to the observable value of these reserves based on a Reinsurance to Close ("RITC") transaction of the Syndicate’s 2015 and prior years of account, which was completed prior to the allocation of purchase price. Management made no change to the initial estimate when establishing its best estimate of reserves for losses and loss expenses at December 31, 2017.
See 'Critical Accounting Estimates – Reserve for Losses and Loss Expenses' section for further details. We caution that conditions and trends that impacted the development of our reserve for losses and loss expenses in the past may not recur in the future.

Acquisition Cost Ratio: The decrease in the acquisition cost ratio to 19.9% in 2017 from 20.2% in 2016 was driven by a decrease in our reinsurance segment. The decrease in the reinsurance segment's acquisition cost ratio was primarily due to changes in business mix, together with favorable adjustments related to loss sensitive features and reinstatement premiums. This decrease was partially offset by an increase in the insurance segment's acquisition cost ratio driven by changes in business mix in our accident and health lines.

Ratio:
The increase in the acquisition cost ratio to 22.3% in 2019 from 20.2% in 2016 from 19.5% in 20152018 was driven byprincipally related to an increase in our reinsurance segment. The increase in the reinsurance segment's acquisition cost ratio was primarily due to the impact of retrocessional contracts, adjustments related to loss-sensitive features in underlying contracts, and higher acquisition costs in certain lines of business due to the increase in the amount of business being written on a proportional basis. This increase was partially offset by a decrease in the insurance segment'ssegment, largely associated with the acquisition cost ratio driven by higher ceding commissions following increased cessions in our professional lines, partially offset by higher variable acquisition costs paid on certain lines of business and favorable federal excise tax adjustment which benefitted 2015.Novae.

General and Administrative Expense Ratio: Ratio:
The decreaseincrease in general and administrative expense ratio to 14.0%13.9% in 20172019 from 16.2%13.1% in 20162018 was primarilymainly driven by a decrease in performance-related compensationnet premiums earned, an increase in information technology costs and professional fees, partially offset by an increase in fees fromassociated with arrangements with strategic capital partners.

The general and administrative expense ratio was consistent in 2016 compared to 2015 at 16.2%. An increase in personnel expenses including transition and severance costs was offset by the benefits of arrangements with our strategic capital partners and an increase in net premiums earned.






RESULTS BY SEGMENTNet Investment Income

Net investment income was $479 million in 2019 compared to $439 million in 2018, an increase of $40 million, primarily attributable to an increase in income from fixed maturities due to the increase in yields and a larger allocation of the portfolio to fixed maturities, together with a realized gain associated with the sale of a privately held investment, partially offset by lower returns from CLO-equities.
Net Investment Gains (Losses)
Net investment gains were $91 million in 2019 compared to net investment losses of $150 million in 2018.
Net investment gains in 2019 mainly reflected net unrealized gains on equity securities and net realized gains on the sale of U.S. government and agency RMBS securities.
Net investment losses in 2018 mainly reflected net realized losses on the sale of agency RMBS, U.S. government and corporate debt securities, and net unrealized losses on equity securities.
Other than temporary impairment ("OTTI") charges were $7 million and $10 million in 2019 and 2018, respectively.
Other Expenses (Revenues), Net
Corporate expenses were $129 million in 2019 compared to $108 million in 2018. The increase was primarily related to ongoing investments in information technology and digital capabilities, personnel costs and professional fees, partially offset by an increase in the allocation of corporate costs to the insurance and reinsurance segments.
The foreign exchange gains of $12 million in 2019 were mainly driven by the impact of the strengthening of the U.S. dollar on the re-measurement of net insurance-related liabilities denominated in euro, partially offset by the impact of the weakening of the U.S. dollar on the re-measurement of net insurance-related liabilities in pound sterling.

The foreign exchange gains of $29 million in 2018 were mainly driven by the impact of the strengthening of the U.S. dollar on the re-measurement of net insurance-related liabilities mainly denominated in pound sterling and euro.


(1) Consolidated underwriting income (loss) is a non-GAAP financial measure as defined in Item 10(e) of SEC Regulation S-K. The reconciliation to net income (loss), the most comparable GAAP financial measure, is provided in 'Management's Discussion and Analysis of Financial Condition and Results of Operations – Executive Summary – Results of Operation'.


Interest expense and financing costs were $68 million in 2019 compared to $67 million in 2018. The increase of $1 million was due to the issuance of 3.900% senior unsecured notes ("3.900% Senior Notes") on June 19, 2019, and the issuance of 4.900% fixed-rate reset junior subordinated notes ("Junior Subordinated Notes") on December 10, 2019, partially offset by the repayment of the 2.65% senior unsecured notes ("2.65% Senior Notes") on April 1, 2019 and the repayment of the Dekania Notes on November 15, 2018.

The financial results for 2019 resulted in a tax expense of $24 million compared to a tax benefit of $29 million in 2018.

The tax expense of $24 million in 2019 was principally due to the generation of pre-tax income in our U.S. and European operations, partially offset by pre-tax losses in our U.K. operations.

The tax benefit of $29 million in 2018 was principally due to the generation of pre-tax losses in our U.K. and European operations, partially offset by income in our U.S. operations.
Reorganization Expenses
Reorganization expenses were $37 million in 2019 compared to $67 million in 2018, related to the transformation program which was launched in 2017. This program encompasses the integration of Novae which commenced in the fourth quarter of 2017, the realignment of our accident and health business, together with other initiatives designed to increase efficiency and enhance profitability, while delivering a customer-centric operating model. These expenses were not included in operating income.
Amortization of Value of Business Acquired
On October 2, 2017, we acquired Novae, a diversified property and casualty insurance and reinsurance business which operates through Syndicate 2007 at Lloyd’s. The acquisition of Novae was undertaken to accelerate the growth strategy of our international insurance business, and to significantly scale up its capabilities to enable us to even better serve our clients and brokers. At the acquisition date, we identified VOBA, which represents the present value of the expected underwriting profit within policies that were in-force at the closing date of the transaction, of $257 million.
VOBA is amortized over its economic useful life and this expense is included in amortization of value of business acquired in the consolidated statement of operations.
Interest in Income (Loss) of Equity Method Investments
Interest in income (loss) of equity method investments represents our share of income (loss) related to investments where we have significant influence over the operating and financial policies of the investee.
Interest in income of equity method investments was $10 million in 2019 compared to $1 million in 2018.

Return on Average Common Equity
Our objective is to generate superior returns on capital that appropriately reward common shareholders for the risks we assume and to grow revenue only when we expect the returns will meet or exceed our requirements. We recognize that the nature of underwriting cycles and the frequency or severity of large loss events in any one year may challenge the ability to achieve a profitability target in any specific period.
ROACE reflects the impact of net income (loss) available (attributable) to common shareholders including net investment gains (losses), foreign exchange losses (gains), reorganization expenses, and interest in income (loss) of equity method investments.
ROACE increased in 2019 compared to 2018, primarily attributable to the investment gains in the year, and a decrease in amortization of VOBA associated with the acquisition of Novae, together with an increase in net investment income and a decrease in reorganization expenses, partially offset by a decrease in underwriting income, an increase in income tax expense, an increase in corporate expenses, and a decrease in foreign exchange gains.
Operating ROACE excludes the impact of net investment gains (losses), foreign exchange losses (gains), reorganization expenses, and interest in income (loss) of equity method investments.
Operating ROACE increased in 2019 compared to 2018, primarily attributable to a decrease in amortization of VOBA associated with the acquisition of Novae, together with an increase in net investment income, partially offset by a decrease in underwriting income, an increase in in income tax expense, and an increase in corporate expenses.
Ex-PGAAP operating ROACE excludes the impact of amortization of VOBA and intangible assets, net of tax, and amortization of acquisition costs, net of tax, associated with Novae's balance sheet at October 2, 2017. Ex-PGAAP operating ROACE for the years ending 2019 and 2018 was 5.2% and 4.7%, respectively.

Book Value per Diluted Common Share
We consider book value per diluted common share to be an appropriate measure of returns to common shareholders, as we believe growth in book value on a diluted basis will ultimately translate into appreciation of our stock price.
In 2019, book value per diluted common share increased by 12%, primarily driven by net income generated and net unrealized investment gains reported in other comprehensive income, partially offset by common dividends declared. The net unrealized investment gains in 2019 reflected a decrease in interest rates and a tightening of credit spreads which positively impacted the market values of fixed maturities.
In 2018, book value per diluted common share decreased by 7%, primarily driven by an increase in net unrealized investment losses reported in other comprehensive income and common dividends declared. The net unrealized investment losses in 2018 reflected a widening of credit spreads which negatively impacted the market values of fixed maturities.


Cash Dividends Declared per Common Share
We believe in returning excess capital to shareholders by way of dividends. Accordingly, dividend policy is an integral part of the value we create for shareholders. Cumulatively, strong earnings have permitted our Board of Directors to approve sixteen successive annual increases in quarterly common share dividends.
Book Value per Diluted Common Share Adjusted for Dividends
Taken together, we believe that growth in book value per diluted common share and common share dividends declared represent the total value created for common shareholders. As companies in the insurance industry have differing dividend payout policies, we believe that investors use the book value per diluted common share adjusted for dividends metric to measure comparable performance across the industry.
In 2019, book value per diluted common share adjusted for dividends increased by $7.47 or 15%, due to net income generated and net unrealized investment gains reported in other comprehensive income.
In 2018, book value per diluted common share adjusted for dividends decreased by $2.38, or 4%, due to net unrealized investment losses reported in other comprehensive income.

Ceded Premiums Written:
Ceded premiums written in 2019 were $2.4 billion, or 35% of gross premiums written, compared to $2.3 billion, or 33%, in 2018 due to an increase in our aviation lines associated with our acquisition of Aviabel. These increases werethe reinsurance segment, partially offset by a decrease in our property lines following our exit from U.S. retailthe insurance operations last year and a decreasesegment.

The increase in our marine lines largelythe reinsurance segment ceded premiums written of $164 million or 21% was primarily driven by timing differences.

2016 versus 2015: Gross premiums writtenincreases in 2016 increased by $137 million or 5% compared to 2015. In 2016, gross premiums written were negatively impacted by our exit from retail insurance operations in Australiacatastrophe, liability, credit and foreign exchange movements. After adjusting for our exit from retail insurance operations in Australiasurety, and foreign exchange movements, gross premium written increased by $200 million primarily attributable to new business in our accident and health property, professional, and liability lines. These increases werelines, partially offset by decreases in our marine,property, and credit and political riskagriculture lines. Our marine lines decreased principally due to reduced new business opportunities, lower rates and timing differences.

The decrease in our credit and political risk line was driven by timing differences.

Current Accident Year Loss Ratio:Ratio:
20172019 versus 2016: 2018:The current accident year loss ratio increaseddecreased to 81.2%68.1% in 20172019 from 67.4%70.7% in 2016.2018. The increasedecrease in the current accident year loss ratio was primarily due to an increase inimpacted by a lower level of catastrophe and weather-related losses. During 20172019, we incurred pre-tax catastrophe and weather-related losses, net losses of $412reinstatement premiums, of $336 million or 19.67.5 points primarily attributable to Hurricanes Harvey, IrmaJapanese Typhoons Hagibis, Faxai and Maria, the two earthquakes in Mexico, the wildfires in NorthernTapah, Hurricane Dorian, Australia Wildfires and Southern California and other U.S. weather-related events. Comparatively, in 20162018, we incurred $121 million, or 6.8 points of losses attributable topre-tax catastrophe and weather-related losses, net of reinstatement premiums, of $430 million or 9.0 points primarily attributable to California Wildfires, Hurricanes Michael and Florence, Typhoon Jebi and other weather-related events.
After adjusting for the impact of the catastrophe and weather-related losses, our current accident year loss ratio increased to 61.6% in 2017 from 60.6% in 2016. The increase in the current accident year loss ratio after adjusting for the impact of the catastrophe and weather-related losses was driven by an increase in attritional loss experience in our property lines together with the adverse impact of rate and trend, partially offset by a decrease in mid-size loss experience in our marine and credit and political risk lines and favorable changes in business mix.
2016 versus 2015: The current accident year loss ratio increased to 67.4% in 2016 from 65.5% in 2015. The increase was primarily due to an increase in catastrophe and weather-related losses. During 2016 we incurred pre-tax catastrophe and weather-related net losses of $121 million, or 6.8% points attributable to U.S. weather-related events, Hurricane Matthew, the Japanese earthquake and the Fort McMurray wildfires. Comparatively, in 2015 we incurred $54 million, or 3.0 points of losses attributable to catastrophe and weather-related events.
After adjusting for the impact of the catastrophe and weather-related losses, our current accident year loss ratio decreased from 62.5% in 2015 to 60.6% in 2016. The decrease2019 from 61.7% in the current accident year loss ratios after adjusting for the impact of the catastrophe and weather-related losses was driven by a decrease in mid-size loss experience in our marine and property lines, partially offset by the adverse impact of rate and trend, an increase in loss experience in our credit and political risk lines as well as changes in business mix.
See ‘Prior Year Reserve Development’ section for further details.
Acquisition Cost Ratio: The increase in the acquisition cost ratio to 15.8% in 2017 from 14.1% in 2016 primarily reflected changes in business mix in our accident and health lines.
The decrease in the acquisition cost ratio to 14.1% in 2016 from 14.5% in 2015, primarily reflected an increase in ceding commissions following increased cessions in our professional lines, partially offset by higher variable acquisition costs paid on certain lines of business, and favorable federal excise tax adjustment which benefitted 2015.


General and Administrative Expense Ratio: The decrease in the general and administrative expense ratio to 16.3% in 2017 from 19.5% in 2016, was primarily driven by a decrease in performance-related compensation costs and an increase in net earned premium, partially offset by general and administrative expenses associated with the acquisition of Novae.
The increase in the general and administrative expense ratio to 19.5% in 2016 from 19.1% in 2015 was primarily driven by the decrease in net earned premium, an increase in personnel expenses as well as transition and severance costs associated with the closure of four U.S. retail business units.

2017 versus 2016: Gross premiums written in 2017 increased by $178 million or 8% compared to 2016. The increase in gross written premiums was attributable to our catastrophe, agriculture, property and motor lines, partially offset by a decrease in our credit and surety lines. The increase in our catastrophe and property lines was driven by new business spread across several cedants. Favorable premium adjustments and reinstatement premiums also contributed to the increase in premiums written in our catastrophe, property and agriculture lines. The increase in our motor lines was driven by new business and favorable premium adjustments, partially offset by the impact of foreign exchange movements and a lower level of premiums written on a multi-year basis during 2017, compared to 2016. The decrease in our credit and surety lines was primarily due to a lower level of premiums written on a multi-year basis.

2016 versus 2015: Gross premiums written in 2016 increased by $229 million or 11% compared to 2015. The increase in gross written premiums was impacted by an increase in the level of premiums written on a multi-year basis in 2016 compared to 2015. This increase in multi-year contracts increased the amount of premium recorded in the current year relating to future years compared to 2015, most notably in the credit and surety and liability lines. On a comparative basis the impact of the multi-year premiums resulted in an increase in gross premiums written of $110 million in 2016 compared to 2015. The increase in gross premiums written was partially offset by foreign exchange movements as the strengthening of the U.S. dollar drove comparative premium decreases in the treaties denominated in foreign currencies, resulting in a decrease of $52 million in gross premiums written in 2016 compared to 2015.

After adjusting for the impact of multi-year contracts and foreign exchange movements, gross premiums written increased by $171 million, or 8% in 2016 compared to 2015. The growth was primarily driven by new business in our liability, marine and other, catastrophe, agriculture, motor and credit and surety lines. In addition, our liability lines increased due to timing differences, our agriculture lines were impacted by a favorable treaty restructuring together with an increased treaty line size, while our credit and surety lines benefited from favorable premium adjustments. These increases were partially offset by a decrease in our property lines, primarily relating to non-renewals, decreases in line sizes on several treaties and the restructuring of a large treaty.
See ‘Critical Accounting Estimates – Premiums’ section for a further discussion of related estimates.

Ceded Premiums Written:

2017 versus 2016: Premiums ceded in 2017 were $489 million, or 20%, of gross premiums written, compared to $304 million, or 14%, in 2016. The increase was due to an increase in premiums ceded to retrocessional treaties which cover our catastrophe, credit and surety, and agriculture lines.



2016 versus 2015: Premiums ceded in 2016 were $304 million, or 14%, of gross premiums written, compared to $105 million, or 5%, in 2015. The increase was due to a new retrocessional cover entered into with Harrington Re which impacted premiums ceded in our liability and professional lines together with increased premiums ceded to new retrocessional treaties which cover our catastrophe and property businesses.

2017 versus 2016: Net premiums earned in 2017 increased by $114 million or 6% compared to 2016. The increase in net premiums earned was driven by an increase in gross premiums earned attributable to new business written in our property and motor lines, as well as favorable premium adjustments impacting our agriculture, motor and property lines, partially offset by decrease in gross premiums earned in our professional lines.
The increase in gross premiums earned was partially offset by an increase in ceded premium earned reflecting the impact of the retrocessions to Harrington Re on our professional lines and increased retrocessions in our agriculture and property lines.

2016 versus 2015: Net premiums earned in 2016 increased by $40 million or 2% ($114 million or 6% increase on a constant currency basis) compared to 2015. The increase in net premiums earned was driven by an increase in gross premiums earned attributable to growth in the business written in our liability, marine and other and catastrophe lines as well as favorable premium adjustments impacting our motor and agriculture lines, partially offset by reduced premiums written in our property lines.

The increase in gross premiums earned was partially offset by increased ceded premiums earned reflecting increased retrocessional covers purchased in our catastrophe and property lines as well as the impact of the new retrocessions to Harrington Re on our liability and professional lines.
Other Insurance Related Income (Loss):
Other insurance related loss in 2017 of $5 million compared to other insurance related income in 2016 of $7 million, a decrease of $12 million, primarily related to a decrease in realized mark-to-market gains on our weather and commodities derivative portfolio and a decrease in profit commissions associated with third party retrocessions, partially offset by fees from strategic capital partners and an increase in realized gains on economic hedges purchased to protect our agriculture line of business against fluctuations in commodity prices.

The other insurance related income in 2016 primarily related to fees from strategic capital partners and realized mark-to-market gains on our weather and commodity derivatives portfolio which were largely offset by realized losses on economic hedges purchased to protect our agriculture line of business against fluctuations in commodity prices.



The other insurance loss in 2015 related to realized losses and mark-to-market adjustments on our weather and commodity derivatives portfolio following unseasonably warm weather conditions in Europe during the fourth quarter of 2015.

Current Accident Year Loss Ratio:
2017 versus 2016: The current accident year loss ratio increased to 87.0% in 2017 from 67.4% in 2016. The increase was primarily due to an increase catastrophe and weather-related losses. During 2017, we incurred pre-tax catastrophe and weather-related losses, net of reinstatement premiums, of $422 million, or 21.1 points attributable to the Hurricanes Harvey, Irma and Maria, the two earthquakes in Mexico, the wildfires in Northern and Southern California and other U.S. weather-related events. Comparatively, in 2016 we incurred $83 million or 4.4 points of net losses attributable to catastrophe and weather-related events.
After adjusting for the impact of the catastrophe and weather-related losses, our current accident year loss ratio increased to 65.9% in 2017 from 63.0% in 2016. The increase in the current accident year loss ratio after adjusting for the impact of the catastrophe and weather-related losses was driven by a large risk loss in our property lines, the impact of the Ogden Rate change in our motor lines and adverse impact of rate and trend.
2016 versus 2015: The current accident year loss ratio increased to 67.4% in 2016 from 65.7% in 2015. The increase was primarily due to an increase in catastrophe and weather-related losses. During 2016, we incurred pre-tax catastrophe and weather-related net losses (net of reinstatement premiums) of $83 million, or 4.4 points attributable to the Fort McMurray wildfires, U.S. weather-related events, Hurricane Matthew, the Japanese, Ecuadorian and South Island earthquakes, the North Calgary hailstorm and the European floods. Comparatively, in 2015 we incurred $46 million or 2.4 points of net losses attributable to catastrophe and weather-related events.
After adjusting for the impact of the catastrophe and weather-related losses, our current accident year loss ratio decreased from 63.3% in 2015 to 63.0% in 2016.2018. The decrease in the current accident year loss ratio after adjusting for the impact of the catastrophe and weather-related losses was drivenprincipally due to the impact of improved pricing over loss trends and changes in business mix.
Estimates for Significant Catastrophe Events:
At December 31, 2019, net reserve for losses and loss expenses included estimated amounts for numerous catastrophe events. We caution that the magnitude and/or complexity of losses arising from these events, in particular Japanese Typhoons Hagibis, Faxai and Tapah, Hurricane Dorian, and the Australia Wildfires which occurred in 2019 together with Hurricanes Michael and Florence, California Wildfires and Typhoon Jebi which occurred in 2018 as well as Hurricanes Harvey, Irma and Maria and the California Wildfires which occurred in 2017 inherently increase the level of uncertainty and, therefore, the level of management judgment involved in arriving at estimated net reserve for losses and loss expenses. As a result, actual losses for these events may ultimately differ materially from current estimates.
Estimated net reserve for losses and loss expenses in relation to the catastrophe events described above were derived from ground-up assessments of in-force contracts and treaties providing coverage in the affected regions. These assessments take into account the latest information available from clients, brokers and loss adjusters. In addition, we consider industry insured loss estimates, market share analyses and catastrophe modeling analyses, when appropriate. Estimates are subject to change as additional loss data becomes available.


We continue to monitor paid and incurred loss development for catastrophe events of prior years and update estimates of ultimate losses accordingly.
Prior Year Reserve Development:
Net favorable prior year reserve development arises from changes to estimates of losses and loss expenses related to loss events that occurred in previous calendar years. Net prior year reserve development by decreased loss experiencesegment was as follows:

Overview
Short-tail business
Short-tail business includes the underlying exposures in our creditthe property and surety lines,other, marine, and aviation reserve classes in the insurance segment, and the underlying exposures in the property and other reserve class in the reinsurance segment.
These reserve classes recognized net adverse prior year reserve development of $85 million in 2019 including net adverse prior year reserve development of $133 million recognized by the reinsurance property and other reserve class, partially offset by net favorable prior year reserve development of $33 million contributed by the ongoinginsurance marine reserve class and net favorable prior year reserve development of $11 million contributed by the insurance property and other reserve class.
The net adverse impactprior year reserve development of rate$133 million recognized by the reinsurance property and trend, andother reserve class was due to an increase in loss estimates attributable to Hurricanes Irma and Michael consistent with industry trends, an increase in loss estimates attributable Typhoon Jebi consistent with updated industry insured loss estimates, and reserve strengthening within the U.S. regional and commercial proportional property books of business and the European proportional property book of business.
These reserve classes contributed net favorable prior year reserve development of $86 million in 2018 reflecting overall better than expected loss emergence related to the 2017 catastrophe events.
Medium-tail business
Medium-tail business consists primarily of insurance and reinsurance professional lines reserve classes, insurance credit and political risk reserve class and reinsurance credit and surety reserve class.
Insurance professional lines reserve class recorded net favorable prior year reserve development of $12 million and $32 million in 2019 and 2018, respectively, reflecting generally favorable experience on older accident years as we continued to transition to more experience based actuarial methods.
Reinsurance professional lines reserve class recorded net favorable prior year reserve development of $21 million in our agriculture lines.2018 reflecting generally favorable experience on older accident years as we continued to transition to more experience based actuarial methods.
See ‘Prior Year Reserve Development’ section for further details.Insurance credit and political risk reserve class recorded net favorable prior year reserve development of $19 million in 2019 reflecting generally better than expected loss emergence.
Acquisition Cost Ratio:Reinsurance credit and surety reserve class recorded net favorable prior year reserve development of $53 million and $33 million in 2019 and 2018, respectively, reflecting generally better than expected loss emergence.
Long-tail business
Long-tail business consists primarily of insurance and reinsurance liability reserve classes and reinsurance motor reserve class.
Insurance liability reserve class recognized net adverse prior year reserve development of $25 million and $22 million in 2019 and 2018, respectively. The decreasenet adverse prior year reserve development in 2019 was primarily related to reserve strengthening within the U.S. excess casualty and U.S. primary casualty books of business. The net adverse prior year reserve development in 2018 was primarily related to reserve strengthening within the U.S. excess casualty book of business.


Reinsurance liability reserve class recognized net favorable prior year reserve development of $31 million and $23 million in 2019 and 2018, respectively. The net favorable prior year reserve development in 2019 and 2018 was due to progressively increased weight given by management to experience based indications on older accident years.
Reinsurance motor reserve class recognized net favorable prior year reserve development of $71 million and $23 million in 2019 and 2018, respectively. The net favorable prior year reserve development in 2019 was impacted by the increase in the acquisition cost ratio to 24.0% in 2017 from 25.7% in 2016 primarily reflectedOgden discount rate and changes in related actuarial assumptions. The Ogden Rate which is used to calculate lump sum awards in U.K. bodily injury cases, changed from minus 0.75% to minus 0.25%, effective August 5, 2019. The net favorable prior year reserve development in 2018 was primarily attributable to non proportional treaty business mix, together with a decreaseon older accident years.
We caution that conditions and trends that impacted the development of reserve for losses and loss expenses in adjustmentsthe past may not recur in the future.

$12 million of net favorable prior year reserve development on professional lines business reflecting generally favorable experience on older accident years as we continued to transition to more experience based actuarial methods.

$11 million of net favorable prior year reserve development on property and other business primarily due to overall better than expected loss emergence related to the 2017 catastrophe events and SuperStorm Sandy, partially offset by reserve strengthening within the international book of business, mainly related to the 2018 accident year.

$25 million of net adverse prior year reserve development on liability business primarily due to reserve strengthening within the U.S. excess casualty and U.S. primary casualty books of business mainly driven by the higher frequency and severity of auto claims and the higher frequency of general liability claims, mainly related to the 2015 and 2017 accident years.

In 2018, we recognized $93 million of net favorable prior year reserve development, the principal components of which were:
$65 million of net favorable prior year reserve development on property and other business primarily due to overall better than expected loss emergence related to the 2017 catastrophe events.

$32 million of net favorable prior year reserve development on professional lines business primarily due to better than expected loss experience, particularly related to the 2014 and 2015 accident years.

$18 million of net favorable prior year reserve development on marine business primarily due to better than expected loss emergence on more recent accident years.

$22 million of net adverse prior year reserve development on liability business primarily due to reserve strengthening within the U.S. excess casualty book of business mainly driven by the higher frequency of large auto and general liability claims mainly related to the 2015 accident year.

The decrease in the generalinformation technology costs and administrative expense ratio to 7.0% in 2016 from 7.7% in 2015, was primarily driven by an increase in net premiums earned, benefits of arrangements with our strategic capital partners, and lower professional fees, partially offset by higher personnel costs.

Corporate Expenses: Our corporate expenses include holding company costs necessary to support our worldwide insurance and reinsurance operations and costs associated with operating as a publicly-traded company. As a percentage of net premiums earned, corporate expenses were 3.1%, 3.2% and 3.0% in 2017, 2016 and 2015, respectively. The increase in corporate expenses in 2017 compared to 2016 was primarily driven by higher personnel costs including senior executive transition costs as well as executive retirement costs, and information technology project costs, partially offset by a decrease in performance-related compensation costs.

The increase in corporate expenses during 2016 compared to 2015 is attributable to adjustments to senior leadership executive stock-compensation awards benefiting 2015, an increase in personnel costs including senior executive transition costs in 2016, partially offset by reorganization related expenses adverse to 2015.

Foreign Exchange Losses (Gains): Some of our business is written in currencies other than the U.S. dollar. Foreign exchange losses in 2017 were driven primarily by the impact of the weakening of the U.S. dollar on the re-measurement of net insurance-related liabilities mainly denominated in pound sterling and euro. In addition, foreign exchange losses included the reclassification of a cumulative translation adjustment balance of $24 million related to our AXIS Specialty Australia from accumulated other comprehensive income on our balance sheet to foreign exchange loss on our income statement due to the wind-down of these operations which was substantially complete at March 31, 2017.

Comparatively, foreign exchange gains in 2016 were driven primarily by the strengthening of the U.S. dollar on the re-measurement of net insurance-related liabilities denominated in pound sterling. During 2015, the foreign exchange gains were primarily driven by the depreciation of the euro, pound sterling and Australian dollar against the U.S. dollar.

Interest Expense and Financing Costs: Interest expense and financing costs are related to interest due on 5.875% Senior Notes issued in 2010, 2.65% Senior Notes and the 5.15% Senior Notes issued in 2014, and 4.0% Senior Notes issued in 2017, as well as Dekania Notes issued by Novae on June 30, 2004. Interest expense and financing costs increased by $4 million in 2017 compared to 2016, primarily attributable to costsfees associated with the Dekania Notes.

Interest expense and financing costs in 2016 were consistentarrangements with 2015 as there were no significant changes to our debt and financing arrangements.

Income Tax (Benefit) Expense: Income tax (benefit) primarily results from income (loss) generated by our foreign operations in the U.S. and Europe. Our effective tax rate, which is calculated as income tax (benefit) expense divided by income before tax including interest in loss of equity method investments, was 2.0%, 1.2%, and 0.5%, in 2017, 2016, and 2015, respectively. This effective rate can vary between years depending on the distribution of net income (loss) amongst tax jurisdictions, as well as other factors.

The tax benefit of $8 million in 2017 was primarily attributable to the geographic distribution of income with the benefit being driven by losses in our U.S. and U.K. operations, share based compensation excess tax benefits which were recognized in the year, a tax adjustment related to the bargain purchase gain recognized in connection with the acquisition of Aviabel,


largely offset by a tax charge of $42 million related to the revaluation of net deferred tax assets associated with the reduction in the U.S. corporate income tax rate from 35% to 21% enacted as part of the U.S. Tax Reform.

The tax rate in 2016 increased compared to 2015. The increase was driven primarily by an increase in comparative European pre-tax income, offset partially by a decrease in comparative pre-tax income in the U.S.

strategic capital partners.


NET INVESTMENT INCOME AND NET REALIZED INVESTMENT GAINS (LOSSES)

Net Investment Income
Net investment income was $479 million in 2019 compared to $439 million in 2018, an increase of $40 million, primarily attributable to an increase in income from fixed maturities due to the increase in yields and a larger allocation of the portfolio to fixed maturities, together with a realized gain associated with the sale of a privately held investment, partially offset by lower returns from CLO-equities.
Net Investment Gains (Losses)
Net investment gains were $91 million in 2019 compared to net investment losses of $150 million in 2018.
Net investment gains in 2019 mainly reflected net unrealized gains on equity securities and net realized gains on the sale of U.S. government and agency RMBS securities.
Net investment losses in 2018 mainly reflected net realized losses on the sale of agency RMBS, U.S. government and corporate debt securities, and net unrealized losses on equity securities.
Other than temporary impairment ("OTTI") charges were $7 million and $10 million in 2019 and 2018, respectively.
Other Expenses (Revenues), Net
Corporate expenses were $129 million in 2019 compared to $108 million in 2018. The increase was primarily related to ongoing investments in information technology and digital capabilities, personnel costs and professional fees, partially offset by an increase in the allocation of corporate costs to the insurance and reinsurance segments.
The foreign exchange gains of $12 million in 2019 were mainly driven by the impact of the strengthening of the U.S. dollar on the re-measurement of net insurance-related liabilities denominated in euro, partially offset by the impact of the weakening of the U.S. dollar on the re-measurement of net insurance-related liabilities in pound sterling.

The foreign exchange gains of $29 million in 2018 were mainly driven by the impact of the strengthening of the U.S. dollar on the re-measurement of net insurance-related liabilities mainly denominated in pound sterling and euro.

The reconciliation to net income (loss), the most comparable GAAP financial measure, is provided in 'Management's Discussion and Analysis of Financial Condition and Results of Operations – Executive Summary – Results of Operation'.


Interest expense and financing costs were $68 million in 2019 compared to $67 million in 2018. The increase of $1 million was due to the issuance of 3.900% senior unsecured notes ("3.900% Senior Notes") on June 19, 2019, and the issuance of 4.900% fixed-rate reset junior subordinated notes ("Junior Subordinated Notes") on December 10, 2019, partially offset by the repayment of the 2.65% senior unsecured notes ("2.65% Senior Notes") on April 1, 2019 and the repayment of the Dekania Notes on November 15, 2018.

The financial results for 2019 resulted in a tax expense of $24 million compared to a tax benefit of $29 million in 2018.

The tax expense of $24 million in 2019 was principally due to the generation of pre-tax income in our U.S. and European operations, partially offset by pre-tax losses in our U.K. operations.

The tax benefit of $29 million in 2018 was principally due to the generation of pre-tax losses in our U.K. and European operations, partially offset by income in our U.S. operations.
Reorganization Expenses
Reorganization expenses were $37 million in 2019 compared to $67 million in 2018, related to the transformation program which was launched in 2017. This program encompasses the integration of Novae which commenced in the fourth quarter of 2017, the realignment of our accident and health business, together with other initiatives designed to increase efficiency and enhance profitability, while delivering a customer-centric operating model. These expenses were not included in operating income.
Amortization of Value of Business Acquired
On October 2, 2017, we acquired Novae, a diversified property and casualty insurance and reinsurance business which operates through Syndicate 2007 at Lloyd’s. The acquisition of Novae was undertaken to accelerate the growth strategy of our international insurance business, and to significantly scale up its capabilities to enable us to even better serve our clients and brokers. At the acquisition date, we identified VOBA, which represents the present value of the expected underwriting profit within policies that were in-force at the closing date of the transaction, of $257 million.
VOBA is amortized over its economic useful life and this expense is included in amortization of value of business acquired in the consolidated statement of operations.
Interest in Income (Loss) of Equity Method Investments
Interest in income (loss) of equity method investments represents our share of income (loss) related to investments where we have significant influence over the operating and financial policies of the investee.
Interest in income of equity method investments was $10 million in 2019 compared to $1 million in 2018.


Financial Measures
We believe that the following financial indicators are important in evaluating performance and measuring the overall growth in value generated for common shareholders:
        
 Year ended and at December 31,2019
 2018
 2017
 
        
 
Return on average common equity

6.3% % (8.6%) 
 Operating return on average common equity4.7% 3.6% (5.3%) 
 Ex-PGAAP operating return on average common equity5.2% 4.7% (4.9%) 
 
Book value per diluted common share(1)
$55.79
 $49.93
 $53.88
 
 Cash dividends declared per common share$1.61
 $1.57
 $1.53
 
 Increase (decrease) in book value per diluted common share adjusted for dividends$7.47
 $(2.38) $(2.86) 
        
(1) Book value per diluted common share represents common shareholders’ equity divided by the number of diluted common share outstanding determined using the treasury stock method. Cash settled restricted stock units are excluded

Return on Average Common Equity
Our objective is to generate superior returns on capital that appropriately reward common shareholders for the risks we assume and to grow revenue only when we expect the returns will meet or exceed our requirements. We recognize that the nature of underwriting cycles and the frequency or severity of large loss events in any one year may challenge the ability to achieve a profitability target in any specific period.
ROACE reflects the impact of net income (loss) available (attributable) to common shareholders including net investment gains (losses), foreign exchange losses (gains), reorganization expenses, and interest in income (loss) of equity method investments.
ROACE increased in 2019 compared to 2018, primarily attributable to the investment gains in the year, and a decrease in amortization of VOBA associated with the acquisition of Novae, together with an increase in net investment income and a decrease in reorganization expenses, partially offset by a decrease in underwriting income, an increase in income tax expense, an increase in corporate expenses, and a decrease in foreign exchange gains.
Operating ROACE excludes the impact of net investment gains (losses), foreign exchange losses (gains), reorganization expenses, and interest in income (loss) of equity method investments.
Operating ROACE increased in 2019 compared to 2018, primarily attributable to a decrease in amortization of VOBA associated with the acquisition of Novae, together with an increase in net investment income, partially offset by a decrease in underwriting income, an increase in in income tax expense, and an increase in corporate expenses.
Ex-PGAAP operating ROACE excludes the impact of amortization of VOBA and intangible assets, net of tax, and amortization of acquisition costs, net of tax, associated with Novae's balance sheet at October 2, 2017. Ex-PGAAP operating ROACE for the years ending 2019 and 2018 was 5.2% and 4.7%, respectively.

Book Value per Diluted Common Share
We consider book value per diluted common share to be an appropriate measure of returns to common shareholders, as we believe growth in book value on a diluted basis will ultimately translate into appreciation of our stock price.
In 2019, book value per diluted common share increased by 12%, primarily driven by net income generated and net unrealized investment gains reported in other comprehensive income, partially offset by common dividends declared. The net unrealized investment gains in 2019 reflected a decrease in interest rates and a tightening of credit spreads which positively impacted the market values of fixed maturities.
In 2018, book value per diluted common share decreased by 7%, primarily driven by an increase in net unrealized investment losses reported in other comprehensive income and common dividends declared. The net unrealized investment losses in 2018 reflected a widening of credit spreads which negatively impacted the market values of fixed maturities.


Cash Dividends Declared per Common Share
We believe in returning excess capital to shareholders by way of dividends. Accordingly, dividend policy is an integral part of the value we create for shareholders. Cumulatively, strong earnings have permitted our Board of Directors to approve sixteen successive annual increases in quarterly common share dividends.
Book Value per Diluted Common Share Adjusted for Dividends
Taken together, we believe that growth in book value per diluted common share and common share dividends declared represent the total value created for common shareholders. As companies in the insurance industry have differing dividend payout policies, we believe that investors use the book value per diluted common share adjusted for dividends metric to measure comparable performance across the industry.
In 2019, book value per diluted common share adjusted for dividends increased by $7.47 or 15%, due to net income generated and net unrealized investment gains reported in other comprehensive income.
In 2018, book value per diluted common share adjusted for dividends decreased by $2.38, or 4%, due to net unrealized investment losses reported in other comprehensive income.

Gross Premiums Written:
2019 versus 2018: Gross premiums written in 2019 decreased by $11 million or 0.2% (increased $88 million or 1% on a constant currency basis(1)) compared to 2018 due to a decrease in the insurance segment, partially offset by an increase in the reinsurance segment.
The decrease in the insurance segment's gross premiums written of $122 million or 3% ($75 million, or 2% on a constant currency basis) was primarily attributable to decreases in property, accident and health, and credit and political risk lines, partially offset by increases in liability, professional lines, and marine lines.
The increase in the reinsurance segment's gross premiums written of $110 million or 4% ($163 million, or 5% on a constant currency basis) was primarily attributable to increases in catastrophe, liability, accident and health, and marine and other lines, partially offset by decreases in motor, credit & surety, and property lines.
Ceded Premiums Written:
Ceded premiums written in 2019 were $2.4 billion, or 35% of gross premiums written, compared to $2.3 billion, or 33%, in 2018 due to an increase in the reinsurance segment, partially offset by a decrease in the insurance segment.

The increase in the reinsurance segment ceded premiums written of $164 million or 21% was primarily driven by increases in catastrophe, liability, credit and surety, and accident and health lines, partially offset by decreases in property, and agriculture lines.

The decrease in the insurance segment ceded premiums written of $6 million or 0.4% was attributable to property lines, partially offset by an increase in liability lines.








(1) Amounts presented on a constant currency basis are non-GAAP financial measures as defined in Item 10(e) of SEC Regulation S-K. The constant currency basis is calculated by applying the average foreign exchange rate from the current year to prior year amounts.

Reinsurance Agreement with Alturas Re Ltd ("Alturas")

In January 2019, we obtained protection for the insurance and reinsurance segments through a reinsurance agreement with Alturas. In connection with the reinsurance agreement, Alturas issued notes on December 19, 2018 to unrelated investors in an amount equal to the full $130 million of coverage provided under the reinsurance agreement covering a one-year period. At the time of the agreement, we concluded that we do not have a variable interest in Alturas as the variability in results is expected to be absorbed entirely by the investors in Alturas. Accordingly, the results of Alturas are not included in the consolidated financial statements. The premium ceded to Alturas for the year ended December 31, 2019 was $78 million.

Reinsurance Agreement with Alturas

In connection with the reinsurance agreement, Alturas issued notes on June 28, 2019 to unrelated investors in an amount equal to the full $39 million of coverage provided under the reinsurance agreement covering a one-year period. At the time of the agreement, we concluded that we do not have a variable interest in Alturas as the variability in results is expected to be absorbed entirely by the investors in Alturas. Accordingly, the results of Alturas are not included in the consolidated financial statements. The premium ceded to Alturas for the year ended December 31, 2019 was $10 million.

2019 Reinsurance Agreement with Northshore Limited ("Northshore")

In June 2019, we obtained catastrophe protection for the insurance and reinsurance segments through a reinsurance agreement with Northshore. In connection with the reinsurance agreement, Northshore issued notes to unrelated investors in an amount equal to the full $165 million of coverage provided under the reinsurance agreement covering a four-year period. At the time of the agreement, we concluded that we do not have a variable interest in the entity, as the variability in results is expected to be absorbed entirely by the investors in Northshore. Accordingly, the results of Northshore are not included in the consolidated financial statements. The premium ceded to Northshore for the year ended December 31, 2019 was $13 million.

2018 Reinsurance Agreement with Northshore Limited

In July 2018, we obtained catastrophe protection for the insurance and reinsurance segments through a reinsurance agreement with Northshore. In connection with the reinsurance agreement, Northshore issued notes to unrelated investors in an amount equal to the full $200 million of coverage provided under the reinsurance agreement covering a three-year period. At the time of the agreement, we concluded that we do not have a variable interest in the entity, as the variability in results is expected to be absorbed entirely by the investors in Northshore. Accordingly, the results of Northshore are not included in the consolidated financial statements. The premium ceded to Northshore for the year ended December 31, 2019 was $16 million. The premium ceded to Northshore for the year ended December 31, 2018 was $17 million.

Changes in net premiums earned reflect period to period changes in net premiums written and business mix, together with normal variability in premium earning patterns.

2019 versus 2018: Net premiums earned in 2019 decreased by $204 million or 4% ($156 million or 3% on a constant currency basis) compared to 2018 due to decreases in the insurance and reinsurance segments.
Net premiums earned in the insurance segment in 2019 decreased by $173 million or 7% ($138 million or 6% on a constant currency basis) compared to 2018 primarily attributable to decreases in property, accident and health, discontinued lines - Novae, marine, and aviation lines, partially offset by increases in professional lines, and liability lines.


Net premiums earned in the reinsurance segment in 2019 decreased by $32 million or 1% ($18 million or 1% on a constant currency basis) compared to 2018 attributable to decreases in credit & surety, motor lines, partially offset by increases in marine and other, accident and health lines.
Other Insurance Related Income (Loss):
Other insurance related income in 2019 was $16 million compared to other insurance related income in 2018 of $11 million, an increase of $6 million, primarily related to the reinsurance segment.

Refer to 'Management’s Discussion and Analysis of Financial Condition and Results of Operations – Other Expenses (Revenues), Net' for further details.
Current Accident Year Loss Ratio:
2019 versus 2018: The current accident year loss ratio decreased to 68.1% in 2019 from 70.7% in 2018. The decrease in the current accident year loss ratio was impacted by a lower level of catastrophe and weather-related losses. During 2019, we incurred pre-tax catastrophe and weather-related losses, net of reinstatement premiums, of $336 million or 7.5 points primarily attributable to Japanese Typhoons Hagibis, Faxai and Tapah, Hurricane Dorian, Australia Wildfires and other weather-related events. Comparatively, in 2018, we incurred pre-tax catastrophe and weather-related losses, net of reinstatement premiums, of $430 million or 9.0 points primarily attributable to California Wildfires, Hurricanes Michael and Florence, Typhoon Jebi and other weather-related events.
After adjusting for the impact of the catastrophe and weather-related losses, the current accident year loss ratio decreased to 60.6% in 2019 from 61.7% in 2018. The decrease in the current accident year loss ratio after adjusting for the impact of the catastrophe and weather-related losses was principally due to the impact of improved pricing over loss trends and changes in business mix.
Estimates for Significant Catastrophe Events:
At December 31, 2019, net reserve for losses and loss expenses included estimated amounts for numerous catastrophe events. We caution that the magnitude and/or complexity of losses arising from these events, in particular Japanese Typhoons Hagibis, Faxai and Tapah, Hurricane Dorian, and the Australia Wildfires which occurred in 2019 together with Hurricanes Michael and Florence, California Wildfires and Typhoon Jebi which occurred in 2018 as well as Hurricanes Harvey, Irma and Maria and the California Wildfires which occurred in 2017 inherently increase the level of uncertainty and, therefore, the level of management judgment involved in arriving at estimated net reserve for losses and loss expenses. As a result, actual losses for these events may ultimately differ materially from current estimates.
Estimated net reserve for losses and loss expenses in relation to the catastrophe events described above were derived from ground-up assessments of in-force contracts and treaties providing coverage in the affected regions. These assessments take into account the latest information available from clients, brokers and loss adjusters. In addition, we consider industry insured loss estimates, market share analyses and catastrophe modeling analyses, when appropriate. Estimates are subject to change as additional loss data becomes available.


We continue to monitor paid and incurred loss development for catastrophe events of prior years and update estimates of ultimate losses accordingly.
Prior Year Reserve Development:
Net favorable prior year reserve development arises from changes to estimates of losses and loss expenses related to loss events that occurred in previous calendar years. Net prior year reserve development by segment was as follows:

Overview
Short-tail business
Short-tail business includes the underlying exposures in the property and other, marine, and aviation reserve classes in the insurance segment, and the underlying exposures in the property and other reserve class in the reinsurance segment.
These reserve classes recognized net adverse prior year reserve development of $85 million in 2019 including net adverse prior year reserve development of $133 million recognized by the reinsurance property and other reserve class, partially offset by net favorable prior year reserve development of $33 million contributed by the insurance marine reserve class and net favorable prior year reserve development of $11 million contributed by the insurance property and other reserve class.
The net adverse prior year reserve development of $133 million recognized by the reinsurance property and other reserve class was due to an increase in loss estimates attributable to Hurricanes Irma and Michael consistent with industry trends, an increase in loss estimates attributable Typhoon Jebi consistent with updated industry insured loss estimates, and reserve strengthening within the U.S. regional and commercial proportional property books of business and the European proportional property book of business.
These reserve classes contributed net favorable prior year reserve development of $86 million in 2018 reflecting overall better than expected loss emergence related to the 2017 catastrophe events.
Medium-tail business
Medium-tail business consists primarily of insurance and reinsurance professional lines reserve classes, insurance credit and political risk reserve class and reinsurance credit and surety reserve class.
Insurance professional lines reserve class recorded net favorable prior year reserve development of $12 million and $32 million in 2019 and 2018, respectively, reflecting generally favorable experience on older accident years as we continued to transition to more experience based actuarial methods.
Reinsurance professional lines reserve class recorded net favorable prior year reserve development of $21 million in 2018 reflecting generally favorable experience on older accident years as we continued to transition to more experience based actuarial methods.
Insurance credit and political risk reserve class recorded net favorable prior year reserve development of $19 million in 2019 reflecting generally better than expected loss emergence.
Reinsurance credit and surety reserve class recorded net favorable prior year reserve development of $53 million and $33 million in 2019 and 2018, respectively, reflecting generally better than expected loss emergence.
Long-tail business
Long-tail business consists primarily of insurance and reinsurance liability reserve classes and reinsurance motor reserve class.
Insurance liability reserve class recognized net adverse prior year reserve development of $25 million and $22 million in 2019 and 2018, respectively. The net adverse prior year reserve development in 2019 was primarily related to reserve strengthening within the U.S. excess casualty and U.S. primary casualty books of business. The net adverse prior year reserve development in 2018 was primarily related to reserve strengthening within the U.S. excess casualty book of business.


Reinsurance liability reserve class recognized net favorable prior year reserve development of $31 million and $23 million in 2019 and 2018, respectively. The net favorable prior year reserve development in 2019 and 2018 was due to progressively increased weight given by management to experience based indications on older accident years.
Reinsurance motor reserve class recognized net favorable prior year reserve development of $71 million and $23 million in 2019 and 2018, respectively. The net favorable prior year reserve development in 2019 was impacted by the increase in the Ogden discount rate and changes in related actuarial assumptions. The Ogden Rate which is used to calculate lump sum awards in U.K. bodily injury cases, changed from minus 0.75% to minus 0.25%, effective August 5, 2019. The net favorable prior year reserve development in 2018 was primarily attributable to non proportional treaty business on older accident years.
We caution that conditions and trends that impacted the development of reserve for losses and loss expenses in the past may not recur in the future.

In 2019, we recognized $53 million of net favorable prior year reserve development, the principal components of which were:

$33 million of net favorable prior year reserve development on marine business primarily due to better than expected loss emergence related to the 2015 through 2017 accident years.

$19 million of net favorable prior year reserve development on credit and political risk business primarily due to better than expected loss emergence related to recent accident years.

$12 million of net favorable prior year reserve development on professional lines business reflecting generally favorable experience on older accident years as we continued to transition to more experience based actuarial methods.

$11 million of net favorable prior year reserve development on property and other business primarily due to overall better than expected loss emergence related to the 2017 catastrophe events and SuperStorm Sandy, partially offset by reserve strengthening within the international book of business, mainly related to the 2018 accident year.

$25 million of net adverse prior year reserve development on liability business primarily due to reserve strengthening within the U.S. excess casualty and U.S. primary casualty books of business mainly driven by the higher frequency and severity of auto claims and the higher frequency of general liability claims, mainly related to the 2015 and 2017 accident years.

In 2018, we recognized $93 million of net favorable prior year reserve development, the principal components of which were:
$65 million of net favorable prior year reserve development on property and other business primarily due to overall better than expected loss emergence related to the 2017 catastrophe events.

$32 million of net favorable prior year reserve development on professional lines business primarily due to better than expected loss experience, particularly related to the 2014 and 2015 accident years.

$18 million of net favorable prior year reserve development on marine business primarily due to better than expected loss emergence on more recent accident years.

$22 million of net adverse prior year reserve development on liability business primarily due to reserve strengthening within the U.S. excess casualty book of business mainly driven by the higher frequency of large auto and general liability claims mainly related to the 2015 accident year.

In 2019, we recognized $26 million of net favorable prior year reserve development, the principal components of which were:

$71 million of net favorable prior year reserve development on motor business primarily due to the impact of the increase in the Ogden Rate and changes in related actuarial assumptions, on several accident years.

$53 million of net favorable prior year reserve development on credit and surety business primarily due to generally better than expected loss emergence, mainly related to accident years 2015 through 2017.

$31 million of net favorable prior year reserve development on liability business due to increased weight given by management to experience based indications on older accident years.

$133 million of net adverse prior year reserve development on property and other business primarily due to an increase in loss estimates attributable to Hurricanes Irma and Michael consistent with industry trends, an increase in loss estimates attributable to Typhoon Jebi consistent with updated industry insured loss estimates, and reserve strengthening within the U.S. regional and commercial proportional property books of business and the European proportional property book of business.

In 2018, we recognized $107 million of net favorable prior year reserve development, the principal components of which were:

$33 million of net favorable prior year reserve development on credit and surety business primarily due to generally better than expected loss emergence, mainly related to accident years 2013 and 2014.

$23 million of net favorable prior year reserve development on motor business primarily due to non proportional treaty business related to older accident years.

$23 million of net favorable prior year reserve development on liability business primarily due to increased weight given by management to experience based indications on older accident years.

$21 million of net favorable prior year reserve development on professional lines business reflecting the generally favorable experience on older accident years as we continued to transition to more experience based actuarial methods.
Acquisition Cost Ratio:
The increase in the acquisition cost ratio to 22.3% in 2019 from 20.2% in 2018 was principally related to an increase in the insurance segment, largely associated with the acquisition of Novae.
General and Administrative Expense Ratio:
The increase in general and administrative expense ratio to 13.9% in 2019 from 13.1% in 2018 was mainly driven by a breakdowndecrease in net premiums earned, an increase in information technology costs and professional fees, partially offset by an increase in fees associated with arrangements with strategic capital partners.

2019 versus 2018: Gross premiums written in 2019 decreased by $122 million or 3% ($75 million or 2% on a constant currency basis) compared to 2018 primarily attributable to property, accident and health, and credit and political risk lines, partially offset by increases in liability, professional lines, and marine lines.
The decrease in property lines was due to the non-renewals associated with underwriting actions taken in recent years to reposition the portfolio, partially offset by new business. The decrease in accident and health lines was due to the cancellation of certain program business. The decrease in in credit and political risk lines was attributable to reduced business opportunities. The increases in liability, professional lines and marine lines were driven by new business and favorable rate changes.
Ceded Premiums Written:

2019 versus 2018: Ceded premiums written in 2019 were $1,467 million, or 40%, of gross premiums written, compared to $1,473 million, or 39%, in 2018. The decrease in ceded premiums written of $6 million was primarily driven by a decrease in property lines, partially offset by an increase in liability lines.

2019 versus 2018: Net premiums earned in 2019 decreased by $173 million or 7% ($138 million or 6% on a constant currency basis) compared to 2018. The decrease was driven by decreases in the gross premiums earned in property, accident and health, discontinued lines - Novae, marine and aviation lines together with an increase in ceded premiums earned in liability lines, partially offset by increases in gross premiums earned in liability and professional lines together with decreases in ceded premiums earned in discontinued lines - Novae and property lines.

Current Accident Year Loss Ratio:
2019 versus 2018: The current accident year loss ratio decreased to 60.8% in 2019 from 67.2% in 2018. The decrease in the current accident year loss ratio was impacted by a lower level of catastrophe and weather-related losses. During 2019, we incurred pre-tax catastrophe and weather-related losses of $84 million, or 3.8 points primarily attributable to Hurricane Dorian, and other weather-related events. Comparatively, in 2018 we incurred pre-tax catastrophe and weather-related losses of $204 million, or 8.7 points primarily attributable to Hurricanes Michael and Florence, California Wildfires, and other weather-related events.
After adjusting for the impact of the catastrophe and weather-related losses, the current accident year loss ratio decreased to 57.0% in 2019 from 58.5% in 2018. The decrease in the current accident year loss ratio after adjusting for the impact of the catastrophe and weather-related losses was principally due to impact of improved pricing over loss trends, and a decrease in loss experience in property lines, partially offset by an increase in loss experience in credit and political risk lines.
Acquisition Cost Ratio:
The increase in the acquisition cost ratio to 21.4% in 2019 from 16.9% in 2018 was principally related to the acquisition of Novae. At the acquisition date, the allocation of the purchase price to the assets acquired and liabilities assumed based on estimated fair values at that date, resulted in the write-off of the deferred acquisition cost asset on Novae's balance sheet as the value of policies in-force on that date are considered within VOBA. Consequently, the absence of $12 million and $121 million of acquisition expense in 2019 and 2018, respectively, benefited the acquisition cost ratio by 0.6 points and 5.1 points, respectively. Adjusting the acquisition cost ratio for these amounts, the acquisition cost ratio in 2019 was comparable to 2018.
General and Administrative Expense Ratio:
The increase in the general and administrative expense ratio to 18.3% in 2019 from 16.8% in 2018 was mainly driven by a decrease in net premiums earned, an increase in the allocation of corporate costs to the segment, and an increase in professional fees, partially offset by a decrease in personnel costs.

2019 versus 2018: Gross premiums written in 2019 increased by $110 million or 4% ($163 million or 5% on a constant currency basis) compared to 2018 primarily attributable to catastrophe, liability, accident and health, and marine and other lines, partially offset by decreases in motor, credit and surety, and property lines.

The increases in catastrophe, liability, accident and health, and marine and other lines were driven by new business. In addition, increased line sizes on a number of treaties, the restructuring of several treaties, and higher level of premiums written on a multi-year basis contributed to the increase in catastrophe and liability lines. The increases in liability, and marine and other lines were also due to premium adjustments.

The decrease in motor lines was driven by non-renewals, decreased line sizes on a number of treaties, and the impact of foreign exchange movements as the strengthening of the U.S. dollar drove comparative premium decreases in treaties denominated in foreign currencies, partially offset by premium adjustments. The decrease in credit and surety lines was driven by non-renewals and premium adjustments, partially offset by new business. The decrease in property lines was primarily due to non-renewals and decreased line sizes on a number of treaties, partially offset by favorable rate changes, the restructuring of several treaties, new business, and premium adjustments.
Ceded Premiums Written:
2019 versus 2018: Ceded premiums written in 2019 were $942 million, or 29%, of gross premiums written, compared to $778 million, or 25%, in 2018. The increase in ceded premiums written was primarily attributable to catastrophe, liability, credit and surety, and accident and health lines, partially offset by decreases in property and agriculture lines.

The increase in catastrophe lines was attributable to an increase in premiums ceded to a new aggregate excess of loss treaty and to the new quota share retrocessional treaties with Alturas, together with additional costs associated with the purchase of catastrophe bond protection and an increase in premium ceded to strategic capital partners. The increases in liability, and accident and health lines were attributable to the increase in premiums ceded to the retrocessional cover with Harrington Re.The increase in credit and surety lines was attributable to an increase in premiums ceded to a new quota share retrocessional treaty.

The decrease in property lines was attributable to the non-renewals of fronting arrangements, together with a decrease in premiums ceded to facultative covers with Harrington Re. The decrease in agriculture lines was attributable to the restructuring of a fronting arrangement and a quota share retrocessional treaty.

2019 versus 2018: Net premiums earned in 2019 decreased by $32 million or 1% ($18 million or 1% on a constant currency basis) compared to 2018. The decrease in net premiums earned was primarily driven by increases in ceded premiums earned in accident and health, credit and surety, and motor lines, together with decreases in gross premiums earned in motor and credit and surety lines, partially offset by increases in gross premium earned in accident and health, and marine and other lines.
Other Insurance Related Income (Loss):
Other insurance related income in 2019 of $14 million compared to other insurance related income in 2018 of $7 million, an increase of $7 million, primarily due to an increase in fees associated with arrangements with strategic capital partners.

 Loss ratio 73.7% 3.9 69.8% (8.3) 78.1% 
             
Current Accident Year Loss Ratio:
2019 versus 2018: The current accident year loss ratio increased to 74.7% in 2019 from 74.2% in 2018. The increase in the current accident year loss ratio was impacted by a higher level of catastrophe and weather-related losses. During 2019, we incurred pre-tax catastrophe and weather-related losses, net of reinstatement premiums, of $252 million, or 10.7 points primarily attributable to Japanese Typhoons Hagibis, Faxai and Tapah, Hurricane Dorian, Australia Wildfires and other weather-related events. Comparatively, in 2018 we incurred pre-tax catastrophe and weather-related losses, net of reinstatement premiums, of $226 million or 9.4 points primarily attributable to California Wildfires, Hurricanes Michael and Florence, Typhoon Jebi and other weather-related events.


After adjusting for the impact of the catastrophe and weather-related losses, the current accident year loss ratio decreased to 64.0% in 2019 from 64.8% in 2018. The decrease in the current accident year loss ratio after adjusting for the impact of the catastrophe and weather-related losses was principally due to the impact of changes in business mix, a decrease in loss experience in property and engineering lines, partially offset by an increase in loss experience in aviation, agriculture and motor lines.
Acquisition Cost Ratio:
The decrease in the acquisition cost ratio to 23.2% in 2019 from 23.5% in 2018 was principally related to changes in business mix, adjustments related to loss sensitive features, and the impact of retrocessional contracts.
General and Administrative Expense Ratio:
The decrease in the general and administrative expense ratio to 4.3% in 2019 from 5.1% in 2018 was mainly driven by an increase in fees associated with arrangements with strategic capital partners, together with decreases in information technology costs and personnel costs, partially offset by a decrease in net premiums earned, and an increase in the allocation of corporate costs to the segment.

Corporate Expenses
Corporate expenses include holding company costs necessary to support our worldwide insurance and reinsurance operations and costs associated with operating as a publicly-traded company. As a percentage of net premiums earned, corporate expenses were 2.8% and 2.3% in 2019 and 2018, respectively.
The increase in corporate expenses in 2019 compared to 2018 was primarily related to ongoing investments in information technology and digital capabilities, an increase in personnel costs and professional fees, partially offset by an increase in the allocation of corporate costs to the insurance and reinsurance segments.

Foreign Exchange Losses (Gains)
Some of our business is written in currencies other than the U.S. dollar. Foreign exchange gains in 2019 were mainly driven by the impact of the strengthening of the U.S. dollar on the re-measurement of net insurance-related liabilities denominated in euro, partially offset by the impact of the weakening of the U.S. dollar on the remeasurement of net insurance-related liabilities denominated in pound sterling.

Foreign exchange gains in 2018 were mainly driven by the impact of the strengthening of the U.S. dollar on the re-measurement of net insurance-related liabilities mainly denominated in pound sterling and euro.


Interest Expense and Financing Costs
Interest expense and financing costs are related to interest due on the 5.875% senior unsecured notes ("5.875% Senior Notes") issued in 2010, the 5.150% senior unsecured notes ("5.150% Senior Notes") issued in 2014, the 4.000% senior unsecured notes ("4.000% Senior Notes") issued in 2017, the 3.900% Senior Notes and the Junior Subordinated Notes issued in 2019.
Interest expense and financing costs increased by $1 million in 2019 compared to 2018, due to the issuance of the 3.900% Senior Notes on June 19, 2019, and the issuance of the Junior Subordinated Notes on December 10, 2019, partially offset by the repayment of the 2.650% Senior Notes on April 1, 2019 and the repayment of the Dekania Notes on November 15, 2018.

Income Tax Expense (Benefit)

Income tax expense (benefit) primarily results from income (loss) generated by our foreign operations in the U.S. and Europe. Our effective tax rate, which is calculated as income tax expense (benefit), divided by income (loss) before tax including interest in income (loss) of equity method investments, was 6.8% and (217.9)%, in 2019 and 2018, respectively. This effective rate can vary between years depending on the distribution of net income (loss) among tax jurisdictions, as well as other factors.

The tax expense of $24 million in 2019 was principally due to the geographic distribution of pre-tax income with the expense being driven by pre-tax income generated in our U.S. and European operations, partially offset by pre-tax losses in our U.K. operations.

The tax benefit of $29 million in 2018 was principally due to the geographic distribution of pre-tax losses with the benefit being driven by pre-tax losses in our U.K. and European operations, partially offset by pre-tax income in our U.S. operations.

The OTTI charges in 2017 primarily reflected realized gains2019 and 2018 included impairments on the sale of ETFs, as a result of the strong performance of global equity markets. This was partially offset bynon-U.S. denominated securities due to foreign exchange losses on non-U.S. denominated fixed maturities, as a result ofassociated with the strengthening of the U.S. dollar during 2017.

2016 versus 2015: Net realized investment losses in 2016 were $61 million compared to net realized investment losses of $138 million in 2015.

OTTI losses in 2017 were $14 million compared to $26 million in 2016 a decrease of $12 million. The decrease in 2017 compared to 2016 was mainly due to higher losses related to non-U.S. denominated securities as a result of the decline in foreign exchange rates against the U.S. dollar in 2016. The current year OTTI losses includedpound sterling and the euro and impairments on non-U.S. denominated securities as a result of foreign exchange losses and non-investment grade corporate debt securities that have had a significant declinedeclined significantly in value.
Change in Fair Value of Investment Derivatives:Derivatives
From time to time, we may economically hedge the foreign exchange exposure of non-U.S. denominated securities by entering into foreign exchange forwardand interest rate risk with derivative contracts.
During 2017, we also introduced the use of interest rate swaps to reduce duration risk of our fixed income portfolio.
During 2017, our2019, foreign exchange hedges resulted in $7$2 million of net lossesgains which primarily related primarily to securities denominated in the Japanese yen,euro which experienced volatility during 2019. We also recorded net losses of $4 million related to interest rate swaps.
During 2018, foreign exchange hedges resulted in $3 million of net gains which primarily related to securities denominated in euro and pound sterling. Eachsterling as each of these currencies experienced volatility during 2017.2018. We also recorded net gains of $2 million related to interest rate swaps.
Given that none of ourOur derivative instruments are not designated as hedges under current accounting guidance, therefore, net unrealized gains (losses) on the hedged securities were recorded in accumulated other comprehensive income in shareholders'the statement of changes in shareholders’ equity.



Total Return
Our investment strategy is to take a long-term view by actively managing our investment portfolio to maximize total return within certain guidelines and constraints.

Overview
The fair value of total investments increased by $1.3$1.1 billion in 2017,2019, driven by the acquisitioninvestment of Novae and Aviabel, portfolio yield andcash balances, the
increase in the market value changesof fixed maturities due to a decrease in interest rates and the tightening of credit spreads, on both investment grade and high-yield corporate debt, and the strongincrease in the market value of equity securities due to the improved performance of global equity markets. This was partially offset by the funding of financing and operating activities.

At December 31, 20172019, fixed maturities had a weighted average credit rating of AA- (2016:(2018: AA-), a book yield of 2.5% (2016: 2.6%2.8% (2018: 3.1%), and an average duration of 3.33.2 years (2016: 3.5(2018: 3.0 years) and duration inclusive of. The interest rate swaps of 3.2 years.swap positions, which reduced duration to 2.8 years at December 31, 2018, were closed during 2019. At December 31, 2017, inclusive of2019, fixed maturities together with short-term investments and cash and cash equivalents (i.e. total investments of $14.0$14.1 billion), thehad a weighted average credit rating wasof AA- (20162018: AA-), the and an average duration was 3.0of 2.9 years (2016: 3.2(2018: 2.6 years), and. At December 31, 2018, duration inclusive of interest rate swaps was 2.92.5 years.
Our methodology for assigning credit ratings to our fixed maturities is in line with the methodology used for the Barclays U.S. Aggregate Bond index. This methodology uses the middle of Standard & Poor's (S&P), Moody's and Fitch ratings. When ratings from only two of these agencies are available, the lower rating is used. When only one agency rates a security, that rating is used.
To calculate the weighted average credit rating for fixed maturities, we assign points to each rating with 29 points for the highest rating (AAA) and 2 points for the lowest rating (D) and then calculate the weighted average based on the fair values of the individual securities. Securities that are not rated by S&P, Moody’s or Fitch are excluded from weighted average calculations. At December 31, 20172019, the fair value of fixed maturities not rated was $53.1$33.5 million (20162018: $42.8$55.9 million).
In addition to managing our credit risk exposure within our fixed maturitymaturities portfolio we also monitor the aggregation of country risk exposure on a group-wide basis (refer to Item 1 'Risk and Capital Management’Management' for further details). Country risk exposure is the risk that events withinin a country, such as currency crises, regulatory changes and other political events, will adversely affect the ability of obligors withinin the country to honor their obligations to us.obligations. For corporate debt and structured securities, we measure the country of risk exposure based on a number of factors including, but not limited to, location of management, principal operations and country of revenues.

G.O. bonds are backed by the full faith and credit of the authority that issued the debt and are secured by the taxing powers of those authorities. Revenue bonds are backed by the revenue stream generated by the services provided by the issuer (e.g. sewer, water or utility projects). As issuers of revenue bonds do not have the ability to draw from tax revenues or levy taxes to fund obligations, revenue bonds may carry a greater risk of default than G.O. bonds.

The fair value of our total hedge funds decreased by $134 million in 2017 driven by $168 million of net redemptions offset by $34 million of price appreciation. Certain of these funds may be subjectRefer to restrictions on redemptions which may limit our ability to liquidate these investments in the short term. See Item 8, Note 6(c)5(c) to the Consolidated Financial Statements 'Investments' for further details on these restrictions and details on unfunded commitments relating to our other investment portfolio.

Overseas deposits include investments in private funds held by Syndicate 2007 in which the underlying investments are primarily U.S. government, Non-U.S. government and corporate fixed maturities. The funds do not trade on an exchange therefore are not included within the available for sale investments category.

Equity Method Investments

During 2016, we paid $108 million including direct transactions costs to acquire 19% of the common equity of Harrington Reinsurance Holdings Limited ("Harrington"), the parent company of Harrington Re, an independent reinsurance company jointly sponsored by AXIS Capitalthe Company and Blackstone.The Blackstone Group L.P. ("Blackstone"). Harrington is not a variable interest entity. Givenentity that we exercise significant influence over this investee weis required to be included in the consolidated financial statements. We account for our ownership interest in Harrington under the equity method of accounting.

During 2017, we recorded an impairment charge of $9 million, related to a U.S. based insurance company, which reduced the carrying value of the investment to $nil. This charge is included in interest in loss of equity method investments in the Consolidated Statement of Operations.

LIQUIDITY AND CAPITAL RESOURCES

LIQUIDITYLiquidity
Liquidity is a measure of a company’s ability to generate cash flows sufficient to meet the short-term and long-term cash requirements of its business operations. We manage our liquidity at both the holding company and operating subsidiary level.
Holding Company
As a holding company, AXIS Capital has no operations of its own and its assets consist primarily of investments in its subsidiaries. Accordingly, AXIS Capital’s future cash flows depend on the availability of dividends or other statutorily permissible distributions, such as returns of capital, from its subsidiaries. The ability to pay such dividends and/or distributions is limited by the applicable laws and regulations of the various countries and states in which AXIS Capital’s subsidiaries operate (refer to Item 8, Note 21 to the Consolidated Financial Statements 'Statutory 'Statutory Financial Information' for further details), as well as the need to maintain capital levels to adequately support (re)insurance and reinsurance operations and to preserve financial strength ratings issued by independent rating agencies. During 2017,2019, AXIS Capital received $768$250 million (2016: $550 million; 2015: $420 million)(2018: $200 million) of distributions from its subsidiaries. AXIS Capital’s primary uses of funds are dividend payments to both common and preferred shareholders, share repurchases, interest and principal payments on debt, capital investments in subsidiaries and payment of corporate operating expenses. We believe the dividend/distribution capacity of AXIS Capital’s subsidiaries, which was $1.1 billion at December 31, 2017,2019, will provide AXIS Capital with sufficient liquidity for the foreseeable future.
Operating Subsidiaries
AXIS Capital’s operating subsidiaries primarily derive cash from the net inflow of premiums less claim payments related to underwriting activities and from net investment income. Historically, these cash receipts have been sufficient to fund the operating expenses of these subsidiaries, as well as to fund dividend payments to AXIS Capital. The subsidiaries’ remaining cash flows are generally reinvestedinvested in our investment portfolio or used to fund acquisitions, and theyportfolio. The remaining cash flows have also been used to fund common share repurchases and to fund acquisitions in recent periods.
The (re)insurance and reinsurance business of our operating subsidiaries inherently providesprovide liquidity, as premiums are received in advance (sometimes substantially in advance) of the time claims are paid. However, the amount of cash required to fund claim payments can fluctuate significantly from period to period, due to the low frequency/high severity nature of certain types of business we write.

Cash outflows also included common share repurchases associated with the vesting of share-settled restricted stock units of $10 million in 2019 ( 2018: $10 million). Any future share repurchases are discretionary, the timing and amount of repurchase transactions depend on a variety of factors including, but not limited to, global insurance and reinsurance, and financial market conditions and opportunities, capital management and regulatory considerations (refer to 'Capital Resources – Share Repurchases' below for further details). In 2018, we also fully redeemed the $36 million of Dekania Notes at par.
Financing cash outflows primarily relate to dividends paid to common and preferred shareholders on a recurring basis and totaled $188 million in 2017 (2016: $172 million, 2015: $159 million). Financing cash outflows also included common share repurchases which totaled $286 million in 2017 ( 2016: $510 million and 2015: $332 million). We note that market share repurchases are discretionary; the timing and amount of the additional repurchase transactions will depend on a variety of factors including, but not limited to, global (re)insurance and financial market conditions and opportunities, capital management and regulatory considerations (refer to 'Capital Resources – Share Repurchases' below for further details). In addition, we redeemed our remaining Series C preferred shares, resulting in a cash outflow of $351 million and issued senior notes, resulting in cash inflows of $346 million in 2017 (refer to Item 8, Note 11(a) of the Consolidated Financial Statements 'Debt and Financing Arrangements' for further details).We used a portion of the proceeds from the issuance of senior notes to repay a Novae term loan of $67 million. Cash outflows in 2016 were partially offset by net cash inflows of $480 million related to the preferred share transactions (refer to 'Capital Resources – Preferred Shares' below for further details).
Our diversified underwriting portfolio has demonstrated an ability to withstand catastrophic losses. We have generated positive operating cash flows in all years since 2003, with the exception of 2009 which was impacted by the global financial crisis. These positive cash flows were generated notwithstanding the impacts of the global financial crisis and the recognition of significant natural catastrophe-related losses during the period. Our net
Net losses and loss expenses, gross of reinstatement premiums, included $257 million for the Japanese Typhoons Hagibis, Faxai and Tapah, Hurricane Dorian, and the Australia Wildfires in 2019, $327 million for Hurricanes Michael and Florence, the California Wildfires, and Typhoon Jebi in 2018, and $744 million for Hurricanes Harvey, Irma and Maria, and the two earthquakes in Mexico and the wildfiresCalifornia Wildfires in Northern and Southern California in 2017; $331 million for Storm Sandy in 2012; $944 million for numerous natural catastrophe and weather events in 2011; $256 million for the Chilean and New Zealand earthquakes in 2010; $408 million for Hurricanes Gustav and Ike in 2008; $1,019 million for Hurricanes Katrina, Rita and Wilma in 2005 and $266 million for Hurricanes Charley, Frances, Ivan and Jeanne in 2004.2017. There remains significant uncertainty associated with our estimates of net losses for certain of these events (refer to the Item 7 'Management’s Discussion and Analysis of Financial Condition and Results of Operations – Underwriting'Underwriting Results – Group, Underwriting Expenses'Consolidated – Current Accident Year Loss Ratio' for further details), as well as the timing of the associated cash outflows.
Should claim payment obligations accelerate beyond our ability to fund payments from operating cash flows, we would utilize our cash and cash equivalent balances and/or liquidate a portion of our investment portfolio. Our investment portfolio is heavily weighted towards conservative, high quality and highly liquid securities. We expect that, if necessary, approximately $13.8$13.6 billion of cash and invested assets at December 31, 20172019 could be available in one to three business days under normal market conditions; of this amount, $7.0$5.3 billion relatesrelated to restricted assets, which primarily support our obligations in regulatory jurisdictions where we operate as a non-admitted carrier (refer to Item 8, Note 6(g)5(g) to the Consolidated Financial Statements 'Investments' for further details). For context, our largest 1-in-250 year return period, single occurrence, single-zone modeled probable maximum loss (Southeast U.S. Hurricane) iswas approximately $0.8 billion,$428 million, net of reinsurance; our claimreinsurance. Claim payments pertaining to such an event would be paid out over a period spanning many months. Our internal risk tolerance framework aims to limit both the loss of capital due to a single event, and the loss of capital that would occur from multiple but perhaps smaller events, in any year (refer to Item 1Risk 'Risk and Capital ManagementManagement' for further details).
We continue to expect that cash flows generated from our operations, combined with the liquidity provided by our investment portfolio, will be sufficient to cover our required cash outflows and other contractual commitments through the foreseeable future. For further details about the anticipated amounts and timing of our contractual obligation and commitments referfuture (refer to 'Contractual'Contractual Obligations and Commitments' below.below for further details).

Capital Resources

CAPITAL RESOURCES
In addition to common equity, we have utilized other external sources of financing, including debt, preferred shares and letter of credit facilities to support our business operations. We believe that we hold sufficient capital to allow us to take advantage of market opportunities and to maintain our financial strength ratings, as well as to comply with various local statutory regulations. We monitor our capital adequacy on a regular basis and will seek to adjust our capital base (up or down) according to the needs of our business.

Share Repurchases

On July 5, 2017, the Company and the board of directors of Novae announced that we agreed on terms of a recommended offer to be made by us to acquire the entire issued and to be issued share capital of Novae. Following the offer, we suspended our open market share repurchase plan.

On December 31, 2017, authorization under the Board-authorized share repurchase plan for common share repurchases through 2017 expired. A common share repurchase plan has not been authorized for 2018.since that date.

Credit andSecured Letter of Credit Facilities
We routinely enter into agreements with financial institutions to obtain secured and unsecured credit and letter of credit facilities. These facilities are primarily used for the issuance of letters of credit, in the normal course of operations, to certain (re)insurance operationsand reinsurance entities that purchase reinsurance protection from us. These letters of credit allow those operations to take credit, under local insurance regulations, for reinsurance obtained in jurisdictions where AXIS Capital’s subsidiaries are not licensed or otherwise admitted as an insurer. The value of our letters of credit outstanding is driven by, amongstamong other factors, the amount of unearned premium,premiums, development of loss development on existing reserves, the payment patterns of suchloss reserves, the


expansion of our business and the loss experience of suchthat business. A portion of these facilities may also be used for liquidity purposes.
Each of our existing facilities is described further below (refer to Item 8, Note 10(b) of the Consolidated Financial Statements 'Debt and Financing Arrangements' for further details).

Secured Letter of Credit Facility

On March 27, 2017,28, 2019 certain of AXIS Capital’sCapital's operating subsidiaries (the "Participating Subsidiaries") amended theiran existing

In the event of default, the lenderCitibank may exercise certain remedies, including the exercise of control over pledged collateral and the termination of the availability of the facility to any or all of the participating operating subsidiaries.Participating Subsidiaries.

Credit Facility

On March 26, 2013, we entered into a $250 million credit facility (the "Credit Facility"), which provided us with combined borrowing and letter of credit issuance capacity up to the aggregate amount of the facility. Under the terms of the Credit Facility, loans are available for general corporate purposes andAt December 31, 2019, letters of credit may be issued inoutstanding were $357 million (refer to Item 8, Note 10 to the ordinary course of business, Interest on loans issued under this facility is payable based on underlying market rates at the time of loan issuance. While any loans are unsecured, we have the option to issue letters of credit on a secured basis in order to reduce associated fees. Letters of credit issued under the Credit Facility are principally being used to support the (re)insurance obligations of our operating subsidiaries. This facility is subject to certain non-financial covenants that we believe are customary Consolidated Financial Statements 'Debt and Financing Arrangements' for facilities of this type, including limitations on fundamental changes, the incurrence of additional indebtedness and liens and certain transactions with affiliates and investments, as defined in the facility documents. Compliance with certain financial covenants that we believe are customary for (re)insurance companies in credit facilities of this type is also required.further details).

On March 27, 2017, the Credit Facility expired.
Available Capacity
At December 31, 2017, we had $387 million outstanding under the LOC Facility. The remaining available capacity under the LOC Facility and the $250 Million Facility is $363 million. At December 31, 2017, we were in compliance with all necessary undertakings of the LOC Facility and the $250 Million Facility.

Shelf Registrations
On November 22, 2016,19, 2019, we filed an unallocated universal shelf registration statement with the SEC, which became effective uponon filing. Pursuant to the shelf registration, we may issue an unlimited amount of equity, debt, warrants, purchase contracts or a combination of thosethese securities. Our intent and ability to issue securities pursuant to this registration statement will depend on market conditions at the time of any proposed offering.


Financial Strength Ratings
Our principal (re)insurance and reinsurance operating subsidiaries are assigned financial strength ratings from internationally recognized rating agencies, including Standard & Poor’s, A.M. Best and Moody’s Investors Service. These ratings are publicly announced and are available directly from the agencies, as well as on our website.
Such financialFinancial strength ratings represent the opinions of the rating agencies on the overall financial strength of a company and its capacity to meet the obligations of its (re)insurance and reinsurance contracts. Independent ratings are one of the important factors that establish oura competitive position in (re)insurance and reinsurance markets. The rating agencies consider many factors in determining the


financial strength rating of an insurance company, including the relative level of statutory surplus necessary to support the business operations of the company. These ratings are based uponon factors considered by the rating agencies to be relevant to policyholders, agents and intermediaries and are not directed toward the protection of investors. Such ratingsRatings are not recommendations to buy, sell or hold securities.

CRITICAL ACCOUNTING ESTIMATES

Our Consolidated Financial StatementsThe consolidated financial statements include certain amounts that are inherently uncertain and judgmental in nature. As a result, we are required to make assumptions and best estimates in order to determine the reported values. We consider an accounting estimate to be critical if: (1) it requires that significant assumptions be made in order to deal with uncertainties and (2) changes in the estimate could have a material impact on our results of operations, financial condition or liquidity.
We believe that the material items requiring such subjective and complex estimates are our:

RESERVE FOR LOSSES AND LOSS EXPENSES
Reserve for Losses and Loss Expenses
Overview
We believe the most significant accounting judgment we make is the estimate of our reserve for losses and loss expenses ("loss reserves"). Our lossLoss reserves represent management’s estimate of the unpaid portion of our ultimate liability for losses and loss expenses ("ultimate losses") for (re)insured and reinsured events that have occurred at or before the balance sheet date. Our lossLoss reserves reflect both claims that have been reported to us ("case reserves") to us and claims that have been incurred but not yet reported to us ("IBNR"). Our loss to us. Loss reserves represent our best estimate of what the ultimate settlement and administration of claims will cost, based on our assessment of facts and circumstances known at that particular point in time.
Loss reserves are not an exact calculation of the liability but instead, are complex estimates. The process of estimating loss reserves involves a number of variables (see (refer to 'Selection of Reported Reserves (Management'sManagement's Best Estimate)'Estimate' below for further details). We review our estimateestimates of loss reserves each reporting period and consider all significant facts and circumstances then known.known at that particular point in time. As additional experience and other data become available and/or laws and legal interpretations change, we may adjust our previous estimates of loss reserves; these adjustmentsreserves. Adjustments are recognized in the period in which they are determined and, therefore they can impact that period's underwriting results either favorably (when reserves established in prior years can be released)(indicating that current estimates are lower than previous estimates) or adversely (when reserves established in prior years require upward adjustment)(indicating that current estimates are higher than previous estimates).
Case Reserves
With respect to our insurance operations,business, we are generally notified of insured losses by our insureds and/or their brokers. Based on this information, our claims personnel estimate our ultimate losses arising from the claim, including the cost of administering the claims settlement process. These estimates reflect the judgment of our claims personnel based on general reserving practices, the experience and knowledge of such personnel regarding the nature of the specific claim and, where appropriate, the advice of legal counsel, loss adjusters and other relevant consultants.
For ourWith respect to reinsurance business, case reserves for reported claimswe are generally established based on reports received fromnotified of losses by ceding companies and/or their brokers. For excess of loss contracts, we are typically notified of insured losses on specific contracts and record a case reserve for the estimated ultimate liability arising from the claim. With respect toFor contracts written on a proportional basis, we typically receive aggregated claims information and record a case reserve for the estimated ultimate liability arising from the claim based on that information. However, our proportionalProportional reinsurance contracts typically require that losses in excess of pre-defined amounts be separately notified so that we can adequately evaluate them. Our claims department evaluates each specific loss notification we receive and records additional case reserves when a ceding company’s reserve for a claim is not considered adequate.
In deciding whether to provide treaty reinsurance, we carefully review and analyze a cedant’s underwriting and risk management practices to ensure appropriate underwriting, data capture and reporting procedures. We also undertake an extensive program of cedant audits, using outsourced legal and industry experience where necessary. This allows us to review cedants’ claims administration practices to ensure that reserves are consistent with exposures, adequately established, and properly reported in a timely manner and also allows us to verify that claims are appropriately handled.manner.
IBNR
The estimation of IBNR is necessary due to potential development on reported claims and the time lagslag between when a loss event occurs and when it is actually reported, to us,which is referred to as thea reporting lag. Reporting lags may arise from a number of factors, including but not limited to, the nature of the loss, the use of intermediaries and complexities in the claims adjusting process. By definition,As we do not have specific information on IBNR, so it must be estimated. IBNR is calculated by deducting incurred losses (i.e. paid losses and case reserves) from management’s best estimate of ultimate losses. In contrast to case reserves, which are established at the contract level, IBNR reserves are generally estimated at an aggregate level and cannot be identified as reserves for a particular loss event or contract. For additional information on reservingcontract (refer to 'Reserving for such events, refer to the 'Reserving For Significant Catastrophic Events' below. below for further details).



Reserving ProcessMethodology
Sources of Information
Our quarterly loss reserving process begins with the collection and analysis of paid and incurred claim data for each of ourthe segments. The segmental data is disaggregated by reservingreserve class and further disaggregated by underwriting year (i.e., theand accident year. Underwriting year in which the contract generating premium and losses incepted). We use underwritingor accident year information is used to analyze our business and subsequently allocate reserves to the respective accident years. Our reservingestimate loss reserves. Reserve classes are selected to ensure that the underlying contracts have homogeneous loss development characteristics, while remaining large enough to make the estimation of trends credible. We review our reservingReserve classes are reviewed on a regular basis and adjust themadjusted over time as our business evolves. ThisThe paid and incurred claim data, in addition to industry benchmarks, serves as a key input to many of the methods employed by our actuaries. The relative weights assigned to our own historical loss data versus industry data vary according to the lengthbased on a number of factors including our historical track record and the development profile for the reservingreserve class being evaluated.evaluated (Seerefer to 'Claim Tail Analysis' below for more detailed information by claim tail class.)further details).
Actuarial Analysis
Multiple actuarial methods are available to estimate ultimate losses. Each method has its own assumptions and its own advantages and disadvantages, with no single estimation method being better than the others in all situations and no one set of assumption variables being meaningful for all reservingreserve classes. The relative strengths and weaknesses of the particular estimation methods when applied to a particular group of claims can also change over time.
The following is a brief description of the reserve estimation methods commonly employed by our actuaries andincluding a discussion of their particular strengths and weaknesses:
 
Expected Loss Ratio Method ("ELR Method"): This method estimates ultimate losses for an accident year or underwriting year by applying an expected loss ratio to the earned or written premium for that year. Generally, expected loss ratios are based on one or more of (a) an analysis of historical loss experience to date, (b) pricing information and (c) industry data, adjusted as appropriate, to reflect changes in rates, loss and exposure trends, and terms and conditions. This method is insensitive to actual incurred losses for the accident year or underwriting year in question and is, therefore, often useful in the early stages of development when very few losses have been incurred. Conversely, the lack of sensitivity to incurred/paid losses for the accident year or underwriting year in question means that this method is usually inappropriate in later stages of an accident year or underwriting year’s development.
Loss Development Method (also referred to as the Chain"Chain Ladder MethodMethod" or Link"Link Ratio Method)Method"): This method assumes that the losses incurred/paid for each accident year or underwriting year at a particular development stage follow a relatively similar pattern. It assumes that on average, every accident year or underwriting year will display the same percentage of ultimate losses incurred/paid at the same point in time after the inception of that year. The percentages incurred/paid are established for each development stage (e.g. 12 months, 24 months, etc.) after examining historical averages from historical loss development data and/or external industry benchmark information. Ultimate losses are then estimated by multiplying the actual incurred/paid losses by the reciprocal of the established incurred/paid percentage. The strengths of this method are that it reacts to loss emergence/payments and that it makes full use of historical claim emergence/payment experience. However, this method has weaknesses when the underlying assumption of stable loss development/payment patterns is not valid. This could be the consequence of changes in business mix, claim inflation trends or claim reporting practices and/or the presence of large claims, amongstamong other things. Furthermore, this method tends to produce volatile estimates of ultimate losses where there is volatility in the underlying incurred/paid patterns. In particular, where the expected percentage of incurred/paid losses is low, small deviations between actual and expected claims can lead to very volatile estimates of ultimate losses. As a result, this method is often unsuitable at early development stages for an accident year or underwriting year.
Bornhuetter-Ferguson Method ("BF Method"): This method can be seen as a combination of the ELR and Loss Development Methods, under which the Loss Development Method is given progressively more weight as an accident year or underwriting year matures. The main advantage of the BF Method is that it provides a more stable estimate of ultimate losses than the Loss Development Method at earlier stages of development, while remaining more sensitiveresponsive to emerging loss development than the ELR Method. In addition, the BF Method allows for the incorporation of external market information through the use of expected loss ratios, whereas the Loss Development Method does not incorporate such information.


As part of our quarterly loss reserve reviewreserving process, our actuaries employ the estimation method(s) that they believe will produce the most reliable estimate of ultimate losses, at that particular evaluation date, for each reservingreserve class and accident year or underwriting year combination. Often, this is a blend (i.e. weighted average) of the results of two or more appropriate actuarial methods. These ultimate loss estimates are generally utilized to evaluate the adequacy of our ultimate loss estimates for previous


accident or underwriting years, as established in the prior reporting period. For the initial estimate of the current accident or underwriting year, the available claim data is typically insufficient to produce a reliable estimate of ultimate losses. As a result, our initial estimateestimates for an accident or underwriting year is generally based on the ELR Method for longer tailed lines and a BF method for shorter tailed lines. The initial ELR for each reservingreserve class is established collaboratively by our actuaries, underwriters and management at the start of the year as part of the planning process, taking into consideration prior accident years’ or underwriting years' experience and industry benchmarks, adjusted after considering factors such as loss and exposure trends, rate differences, changes in contract terms and conditions, business mix changes and other known differences between the current year and prior accident or underwriting years. The initial expected loss ratios for a given accident or underwriting year may be modified over time if the underlying assumptions, such as loss development or premium rate changes, differ from the original assumptions.
Key Actuarial Assumptions
The use of the above actuarial methods requires us to make certain explicit assumptions, the most significant of which are: (1) expected loss ratios and (2) loss development patterns.
In earlier years, we placed significant reliance on industry benchmarks in establishing expected loss ratios and selecting loss development patterns. Over time, we have placed more reliance on our historical loss experience in establishing these ratios and selecting these patterns where we believe the weight of our experience has become sufficiently credible for consideration. The weight given to our experience differs for each of the three claim tail classes (refer to 'Claim Tail Analysis' below for further details). In establishing expected loss ratios for the insurance segment, we give consideration to a number of other factors, including exposure trends, rate adequacy on new and renewal business, ceded reinsurance costs, changes in claims emergence and our underwriters’ view of terms and conditions in the market environment. For the reinsurance segment, expected loss ratios are based on a contract-by-contract review, which considers information provided by clients together with estimates provided by our underwriters and actuaries about the impact of changes in pricing, terms and conditions and coverage. We also have considered the market experience of some classes of business as compiled and analyzed by an independent actuarial firm, as appropriate.

In order to capture the key dynamics of loss reserve development and potential volatility, reserve classes should be considered according to their potential expected length of loss emergence and settlement, generally referred to as the "tail". We consider our business to consist of three claim tail classes: short-tail, medium-tail and long-tail. Favorable development on prior accident year reserves indicates that current estimates are lower than previous estimates, while adverse development on prior accident year reserves indicates that current estimates are higher than previous estimates. Below is a discussion of the specifics of our loss reserve process as it applies to each claim tail class, as well as commentary on the factors contributing to our historical loss reserve development for each class.
Short-tail Business
Short-tail business generally includes exposures for which losses are usually known and paid within a relatively short period of time after the underlying loss event has occurred. Our short-tail business primarily relates to property coverages and includes terrorism, accident and health, discontinued lines - Novae, marine, and aviation hull and war business in the insurance segment, together with the catastrophe, property, engineering, agriculture, marine and other, accident and health, and discontinued lines - Novae business in the reinsurance segment.
The key actuarial assumptions for short-tail business in early accident years were primarily developed with reference to industry benchmarks for expected loss ratios and loss development patterns. As our historical loss experience amassed, it gained credibility and became relevant for consideration in establishing these key actuarial assumptions. As a result, we gradually increased the weighting assigned to our historical loss experience in selecting the expected loss ratios and loss development patterns utilized to establish estimates of ultimate losses for an accident year.
Due to the relatively short reporting and settlement patterns for short-tail business, we generally place more weight on experience-based methods and other qualitative considerations in establishing reserves for recent and more mature accident years. Refer to 'Underwriting Results – Consolidated – Prior Year Reserve Development' for further details.
Although estimates of ultimate losses for short-tail business are inherently more certain than for medium and long-tail business, significant judgment is still required. For example, much of our excess insurance and excess of loss reinsurance business has high attachment points, therefore, it is often difficult to estimate whether claims will exceed those attachment points. Also, the inherent uncertainties relating to catastrophe events further add to the complexity of estimating potential exposure. In addition, we use managing general agents ("MGAs") and other producers for certain business in the insurance


segment which can delay the reporting of loss information to us. We expect that the majority of development for an accident year or underwriting year will be recognized in the subsequent one to three years.
Medium-tail Business
Medium-tail business generally has claim reporting and settlement periods that are longer than those of short-tail reserve classes. Our medium-tail business primarily consists of insurance and reinsurance professional lines, reinsurance credit and surety, aviation liability business in the insurance and discontinued lines - Novae in the insurance segment. We also consider insurance credit and political risk business to have a medium tail, due to the complex nature of claims and the potential additional time that may be required to realize subrogation assets.
For our earliest accident and underwriting years, initial key actuarial expected loss ratio and loss development assumptions were established utilizing industry benchmarks. Due to the longer claim tail, the length of time required to develop credible loss history for use in the loss reserving process is greater for medium-tail business than for short-tail business. Our reserving approach for medium-tail business is tailored by line of business, with significant lines of business being specifically addressed below:
Insurance and Reinsurance Professional Lines
For professional lines business and discontinued lines - Novae, claim payment and reporting patterns are typically medium to long-tail in nature. This business is predominantly written on a claims-made basis.
With respect to key actuarial assumptions, we rely on our loss experience when establishing expected loss ratios and selected loss development patterns. Loss reporting patterns for professional lines business tend to be volatile, causing instability in actuarial indications based on incurred loss data until an accident year or underwriting year matures. Consequently, initial loss reserves for an accident year or underwriting year are generally based on an ELR method and the consideration of relevant qualitative factors. As accident years and underwriting years mature, we increasingly give more weight to methods that reflect our experience until selections are based almost exclusively on experience-based methods. We evaluate the appropriateness of the transition to experience-based methods at the reserve class level, commencing this transition when we believe that our incurred loss development is sufficient to produce meaningful actuarial indications. The rate at which we transition fully to sole reliance on experience-based methods can vary by reserve class and by year, depending on our assessment of the stability and relevance of such indications. For some professional lines in the insurance segment, we also rely on the evaluation of the open claim inventory in addition to the commonly employed actuarial methods when establishing reserves.
Our transition from the ELR method to experience-based methods began in 2008, when we commenced gradual transition for the 2004 and prior accident years. As our loss history continued to develop, the transition was expanded to include additional accident years. Refer to 'Underwriting Results – Consolidated – Prior Year Development' for further details.
Reinsurance Credit and Surety
For reinsurance credit and surety business, initial and most recent underwriting year loss projections are generally based on the ELR method, with consideration given to qualitative factors. Given that there is a quicker and more stable reporting pattern for trade credit and mortgage business, we generally commence the transition to experience-based methods for these lines of business sooner than for surety business.
Insurance Credit and Political Risk
Refer to 'Reserving for Credit and Political Risk Business' below for a more detailed discussion of specific loss reserve issues related to this business.     When considering prior year reserve development for this line of business, it is important to note that the multi-year nature of the credit business distorts loss ratios when a single accident year is considered in isolation. In recent years, the average term of these contracts has been four to five years. Premiums for these contracts generally earn evenly over the contract term, therefore, are reflected in multiple accident years. In contrast, losses incurred on these contracts, which can be characterized as low in frequency and high in severity, are reflected in a single accident year.
The estimation of the value of recoveries on credit and political risk business requires significant management judgment. At December 31, 2019, estimated recoveries on credit and political risk business were $35 million (2018: $24 million).
Long-tail Business
In contrast to short and medium-tail business, the claim tail for long-tail business is expected to be notably longer, as claims are often reported and ultimately paid or settled years, or even decades, after the related loss events occur. Our long-tail business primarily relates to liability business written in the insurance and reinsurance segments, and reinsurance motor business, and discontinued lines - Novae in the insurance and reinsurance segments.


As a general rule, estimates of accident year or underwriting year ultimate losses for long-tail business are notably more uncertain than those for short and medium-tail business. Factors that contribute additional uncertainty to estimates for long-tail business include, but are not limited to:
more significant weight given to industry benchmarks in forming our key actuarial assumptions;
potential volatility of actuarial estimates, given the number of years of development it takes to produce a meaningful incurred loss as a percentage of ultimate losses;
inherent uncertainties about loss trends, claims inflation (e.g. medical, judicial, social) and general economic conditions; and
the possibility of future litigation, legislative or judicial change that may impact future loss experience relative to the prior industry loss experience relied on in reserve estimation.
To date, key actuarial assumptions for long-tail business have been derived from a combination of industry benchmarks supplemented our historical loss experience. While we consider industry benchmarks that we believe reflect the nature and coverage of our business, actual loss experience may differ from the benchmarks based on industry averages.
Due to the length of the development tail for this business, reserve estimates for most accident years and underwriting years are predominantly based on the BF or ELR method and the consideration of qualitative factors. As part of our quarterly loss reserving process, we monitor actual paid and incurred loss emergence relative to expected loss emergence based on selected loss development patterns. The drivers of any unfavorable loss emergence are investigated and, as a result, have led to an immediate recognition of adverse development in some instances.
Prior to the fourth quarter of 2012, we did not recognize any favorable loss emergence. As a result, during some periods, we recognized net adverse prior year reserve development for insurance liability business in light of unfavorable loss emergence for certain reserve class and accident year combinations.
Commencing with the fourth quarter 2012 loss reserving process, we began to give weight to actuarial methods that reflect our experience for liability business as we believed that our oldest accident years were at a stage of expected development where such methods would produce meaningful actuarial indications.
In 2019, we continued to give weight to experience-based methods on the earlier years for insurance and reinsurance liability lines of business leading to the recognition of net favorable prior year reserve development on the reinsurance liability reserve class.
Reserving for Credit and Political Risk Business
Our insurance credit and political risk insurance business consists primarily of credit insurance and confiscation, expropriation, nationalization and deprivation coverages ("CEND"). Claims for this business tend to be characterized by their severity risk, as opposed to their frequency risk. Therefore,risk therefore, claim payment and reporting patterns are anticipated to be volatile. Under the notification provisions of our credit insurance policies, we anticipate being advised of an insured event within a relatively short time period. As a result,Consequently, we generally estimate ultimate losses based on a contract-by-contract analysis which considers the contracts’ terms, the facts and circumstances of underlying loss events and qualitative input from claims managers.
An important and distinguishing feature of many of these contracts though, is ourthe contractual right, subsequent to payment of a claim to ouran insured, to be subrogated to, or otherwise have an interest in, the insured’s rights of recovery under an insured loan or facility agreement. These estimated recoveries are recorded as an offset to our credit and political risk loss reserves. The lag between the date of a claim payment and ourthe ultimate recovery from the corresponding security can result in negative case reserves at a point in time (as was the case at December 31, 20172019 and 2016)2018). The nature of the underlying collateral is specific to each transaction andtherefore we also estimate the value of this collateral on a contract-by-contract basis. This valuation process is inherently subjective and involves the application of management’s judgment because active markets for the collateral often do not exist. Our estimatesEstimates of valuevalues are based on numerous inputs, including information provided by our insureds, as well as third partythird-party sources including rating agencies, asset valuation specialists and other publicly available information. We also assess any post-event circumstances, including restructurings, liquidations and possession of asset proposals/agreements.
In some instances, uponon becoming aware of a loss event related to our credit and political risk business, we negotiate a final settlement of all of our policy liabilities for a fixed amount. In most circumstances, this occurs when the insured moves to realize the benefit of the collateral that underlies the insured loan or facility and presents us with a net settlement proposal that represents a full and final payment by us under the terms of the policy. In consideration for this payment, we secure a cancellation of the policy, or a release of all claims, and waive our right to pursue a recovery of these settlement payments


against the security that may have been available to us under the insured loan or facility agreement. In certain circumstances, cancellation by way of net settlement or full payment can result in an adjustment ofto the net premium to be received and earned onassociated with the policy.
Reserving Forfor Significant Catastrophic Events
We cannot estimate losses from widespread catastrophic events, such as hurricanes and earthquakes, using the traditional actuarial methods described above. Rather, lossLoss reserves for such events are estimated by management after a catastrophe occurs by completing an in-depth analysis of individual contracts which may potentially behave been impacted by the catastrophic event. This in-depth analysis may rely on several sources of information including:
estimates of the size of insured industry losses from the catastrophic event and our corresponding market share;
a review of our portfolio of contracts performed to identify those contracts which may be exposed to the catastrophic event;


a review of modeled loss estimates based on information previously reported by customers and brokers, including exposure data obtained during the underwriting process;
discussions of the impact of the event with our customers and brokersbrokers; and
catastrophe bulletins published by various independent statistical reporting agencies.
We generally use a blend of these information sources to arrive at our aggregate estimate of the ultimate losses arising from the catastrophic event. In subsequent reporting periods, we review changes in paid and incurred losses in relation to each significant catastrophe and adjust our estimates of ultimate losses for each event if there are developments that are different from our previous expectations; such adjustmentsexpectations. Adjustments are recorded in the period in which they are identified.
There are additional risks affecting our ability to accurately estimate ultimate losses for catastrophic events. For example, the estimationestimates of loss reserves related to hurricanes and earthquakes can be affected by factors including, but not limited to:to, the inability to access portions of impacted areas, infrastructure disruptions, the complexity of factors contributing to losses, legal and regulatory uncertainties, complexities involved in estimating business interruption losses and additional living expenses, the impact of demand surge, fraud and the limited nature of information available. For hurricanes, additional complex coverage factors may include determining whether damage was caused by flooding versusor wind, evaluating general liability and pollution exposures, and mold damage. The timing of a catastrophe, for example, near the end of a reporting period, can also affect the level of information available to us to estimate loss reserves for that reporting period.
Our results Results of operations for each of 2017, 20162019 and 20152018 were impacted by natural catastrophe activity. For a discussion of these events and the remaining associated uncertainties, referactivity (refer to Item 7 'Underwriting'Underwriting Results – Group, Underwriting, Expenses'Consolidated – Current Accident Year Loss Ratio' for further details).
Key Actuarial Assumptions
The use of the above actuarial methods requires us to make certain explicit assumptions, the most significant of which are: (1) expected loss ratios and (2) loss development patterns.
We began operations in late 2001. In our earlier years, we placed significant reliance on industry benchmarks in establishing our expected loss ratios. Over time, we have placed more reliance on our historical loss experience in establishing these ratios where we believe the weight of our own actual experience has become sufficiently credible for consideration. The weight given to our experience differs for each of our three claim tail classes and is discussed further in 'Claim Tail Analysis' below. In establishing expected loss ratios for our insurance segment, we give consideration to a number of other factors, including exposure trends, rate adequacy on new and renewal business, ceded reinsurance costs, changes in claims emergence and our underwriters’ view of terms and conditions in the market environment. For our reinsurance segment, expected loss ratios are based on a contract-by-contract review, which considers information provided by clients together with estimates provided by our underwriters and actuaries about the impact of changes in pricing, terms and conditions and coverage. We also have considered the market experience of some classes of business as compiled and analyzed by an independent actuarial firm, as appropriate.
Similarly, we also placed significant reliance on industry benchmarks in selecting our loss development patterns in earlier years. Over time, we have given varying degrees of weight to our own historical loss experience, discussed further in 'Claim Tail Analysis' below.
Selection of Reported Reserves (Management’sManagement’s Best Estimate)

Estimate
Our quarterly loss reserving process involves the collaboration of our underwriting, claims, actuarial, legal, ceded reinsurance and finance departments, includes various segmental committee meetings and culminates with the approval of a single point best estimate by our Group Reserving Committee, which comprises senior management. In selecting this best estimate, management considers actuarial estimates and applies informed judgment regarding qualitative factors that may not be fully captured in these actuarial estimates. Such factors include, but are not limited to: the timing of the emergence of claims, volume and complexity of claims, social and judicial trends, potential severity of individual claims and the extent of internalour historical loss data versus industry information. While these qualitative factors are considered in arriving at the point estimate, no specific provisions for qualitative factors are established.



With regard to establishing the fair value of reserves for losses and loss expenses for Syndicate 2007 on October 2, 2017,Novae at the acquisition date, weight was given to the observable value of these reserves based on a Reinsurance to Close ("RITC")the RITC transaction of the Syndicate’s 2015 and prior years of account of Syndicate 2007, which was completed prior to the allocation of purchase price. Management made no change to the initial estimate when establishing its best estimate of reserves for losses and loss expenses at December 31, 2017. This is consistent with our general approach of recognizing all or part of the anticipated cost of third partythird-party liability commutations if the transaction has either completed or is considered sufficiently likely to be completed in the near term. 

Beginning in 2013, we significantly enhanced the capabilities and resources dedicated to the actuarial reserving function. Consequently, from the first quarter of 2014, management began to rely uponon its internal actuarial reserving function for theits quarterly reserve evaluationloss reserving process rather than utilizing the services of an independent actuarial firm. On an annual basis, we use an independent actuarial firm to provide an actuarial opinion on the reasonableness of our loss reserves for each of our operating subsidiaries and statutory reporting entities; suchentities as these actuarial opinions are required to meet various insurance regulatory requirements. The actuarial firm also discusses its conclusions from the annual review with management and presents its findings to our Board of Directors.

In order to capture the key dynamics of our loss reserve development and potential volatility, our reserving classes should be considered according to their potential expected length of loss emergence and settlement, generally referred to as the "tail". We consider our business to consist of three claim tail classes: short-tail, medium-tail and long-tail. Below is a discussion of the specifics of our loss reserve process as they apply to each claim tail class, as well as commentary on the factors contributing to our historical loss reserve development for each class. Favorable development on prior accident year reserves indicates that our current estimates are lower than our previous estimates, while adverse development indicates that our current estimates are higher than our previous estimates.


Short-Tail Business
Our short-tail business generally includes exposures for which losses are usually known and paid within a relatively short period of time after the underlying loss event has occurred. Our short-tail business primarily relates to property coverages and includes the majority of our property, terrorism and marine business and certain aviation business within our insurance segment, together with the property, catastrophe and agriculture business within our reinsurance segment as well as discontinued lines - Novae.
The key actuarial assumptions for our short-tail business in our early accident years were primarily developed with reference to industry benchmarks for both expected loss ratios and loss development patterns. As our own historical loss experience amassed, it gained credibility and became relevant for consideration in establishing these key actuarial assumptions. As a result, we gradually increased the weighting assigned to our own historical experience in selecting the expected loss ratios and loss development patterns utilized to establish our estimates of ultimate losses for an accident year.
Due to the relatively short reporting and settlement patterns for our short-tail business, we generally place more weight upon experience-based methods and other qualitative considerations in establishing reserves for both our recent and more mature accident years. As our experience developed more favorably than our initial expectations, we recognized favorable prior year development on short-tail business in recent years. See 'Underwriting Results – Group, Prior Year Reserve Development' for a discussion of the net favorable reserve development recognized when re-estimating our ultimate losses for short-tail business during the past three years.
Although our estimates of ultimate losses for our short-tail business are inherently less uncertain than for our medium and long-tail business, significant judgment is still required. For example, because much of our excess insurance and excess of loss reinsurance business has high attachment points, it is often difficult to estimate whether claims will exceed those attachment points. Also, the inherent uncertainties relating to catastrophe events previously discussed, together with our typically large line sizes, further add to the complexity of estimating our potential exposure. In addition, we use MGAs and other producers for certain business within our insurance segment; this can delay the reporting of loss information to us. We expect that the majority of development for an accident year or underwriting year will be recognized in the subsequent one to three years.
Medium-Tail Business
Our medium-tail business primarily consists of professional lines (re)insurance, discontinued lines - Novae, and trade credit and surety reinsurance business. Certain other classes of business, including aviation hull and engineering reinsurance, are also considered to have a medium-tail. Claim reporting and settlement periods on these classes are generally longer than those of our short-tail reserving classes. We also consider our credit and political risk insurance business to have a medium tail, due to the complex nature of claims and the potential additional time that may be required to realize our subrogation assets.
For our earliest accident and underwriting years, our initial key actuarial expected loss ratio and loss development assumptions were established utilizing industry benchmarks. Due to the longer claim tail, the length of time required to develop our own credible loss history for use in the reserving process is greater for our medium-tail business than for our short-tail business. As a result, the number of years where we relied heavily on industry benchmarks to establish our key actuarial assumptions is greater for our medium-tail business. Our reserving approach for medium-tail business is tailored by line of business, with our significant lines being specifically addressed below.
Professional Lines (Re)insurance
For our professional lines business and discontinued lines - Novae, claim payment and reporting patterns are typically medium to long-tail in nature. The underlying business is predominantly written on a claims-made basis, with the majority of reinsurance treaties being written on a risks attaching basis. With respect to our key actuarial assumptions, we are progressively giving more weight to our own experience when establishing our expected loss ratios and our selected loss development patterns, though we continue to consider industry benchmarks.
Loss reporting patterns for professional lines business tend to be volatile, causing instability in actuarial indications based on incurred loss data until an accident year matures for a number of years. Consequently, our initial loss reserves for an accident year or underwriting year are generally based upon an ELR method and the consideration of relevant qualitative factors. As accident years and underwriting years mature, we increasingly give more weight to methods that reflect our actual experience


until our selections are based almost exclusively on experience-based methods. We evaluate the appropriateness of the transition to experience-based methods at the reserving class level, commencing this transition when we believe that our incurred loss development is sufficient to produce meaningful actuarial indications. The rate at which we transition fully to sole reliance on experience-based methods can vary by reserving class and by year, depending on our assessment of the stability and relevance of such indications. For some professional lines in our insurance segment, we also rely upon the evaluation of the open claim inventory in addition to the commonly employed actuarial methods when establishing reserves.
Our transition from the ELR method to experience-based methods began during 2008, when we commenced gradual transition for the 2004 and prior accident years. As our loss history continued to develop, the transition was expanded to include additional accident years. With the exception of the experience in the insurance professional lines during 2014 and 2015, our actual loss experience has generally been more favorable than initial expectations and the transition led to the recognition of net favorable prior year reserve development in recent years. During 2014, Management continued to rely upon experience-based methods, an evaluation of the open claims inventory and other qualitative factors in establishing the ultimate loss estimates for the insurance professional lines portfolio. During 2015, updated actuarial assumptions in our Australian book of business impacting accident years 2010 to 2014, resulted in strengthening of the insurance professional lines portfolio, partially offset by favorable development in certain U.S. professional lines classes.
See 'Underwriting Results – Group, Prior Year Development' for a discussion of the development recognized during the last three years.
We believe that there continues to be a relatively higher level of uncertainty around ultimate loss estimates for the business classes impacted by the global financial crisis in the 2007 to 2009 accident years. As a result, we continue to rely upon the evaluation of the open claims inventory in addition to the consideration of the actuarial indications, while exercising a greater degree of caution in recognizing potential favorable loss emergence, when establishing loss reserves for these accident years.
Trade Credit and Surety Reinsurance
For our trade credit and surety reinsurance business, our initial and most recent underwriting year loss projections are generally based on the ELR method, with consideration given to qualitative factors. Given that there is a quicker and more stable reporting pattern for trade credit business, we generally commence the transition to experience-based methods sooner than for the surety business.
Credit and Political Risk Insurance
Refer to the previous discussions of this business under ‘Reserving Process – Actuarial Analysis’ and ‘Reserving Process – Reserving for Credit and Political Risk Business’ above for a discussion of specific loss reserve issues related to this business. When considering prior accident year reserve development for this line of business, it is important to note that the multi-year nature of the credit business distorts loss ratios when a single accident year is considered in isolation. In recent years, the average term of these contracts has been four to five years. The premiums we receive are generally earned evenly over the contract term, thus spanning multiple accident years. In contrast, losses incurred on these contracts, which can be characterized as low in frequency and high in severity, are reflected in a single accident year.
As previously described, the estimation of the value of our recoveries on credit and political risk business requires significant management judgment. At December 31, 2017, our total estimated recoveries on credit insurance business were $57 million, while comparatively, at December 31, 2016, our estimated recoveries were $73 million.

Long-Tail Business
In contrast to our short and medium-tail business, the claim tail for our long-tail business is expected to be notably longer, as claims are often reported and ultimately paid or settled years, or even decades, after the related loss events occur. Our long-tail business primarily relates to liability business written in our insurance and reinsurance segments, as well as our motor reinsurance business and discontinued lines - Novae.
As a general rule, our estimates of accident year or underwriting year ultimate losses for our long-tail business are notably more uncertain than those for our short and medium-tail business. Factors that contribute additional uncertainty to estimates for our long-tail business include, but are not limited to:
The more significant weight given to industry benchmarks in forming our key actuarial assumptions;


The potential volatility of actuarial estimates, given the number of years of development it takes to produce a meaningful incurred loss as a percentage of ultimate losses;
Inherent uncertainties about loss trends, claims inflation (e.g. medical, judicial, social) and general economic conditions; and
The possibility of future litigation, legislative or judicial change that may impact future loss experience relative to the prior industry loss experience relied upon in reserve estimation.
To date, our key actuarial assumptions for our long-tail business have been derived extensively from industry benchmarks supplemented with our own historical experience. Given our relatively short operating history in comparison to the development tail for this business, we do not believe that our own historical loss development for our long-tail business has amassed an appropriate volume to serve as a fully credible input into the key actuarial assumptions previously outlined. While we consider industry benchmarks that we believe reflect the nature and coverage of our business, our actual loss experience may differ from the benchmarks based on industry averages.
Due to the length of the development tail for this business, our reserve estimates for most accident years and underwriting years are predominantly based on the BF or ELR method and the consideration of qualitative factors. As part of our quarterly reserving process, we monitor actual paid and incurred loss emergence relative to expected loss emergence based on our selected loss development patterns. The drivers of any unfavorable loss emergence are investigated and, as a result, have led to an immediate recognition of adverse development in some instances. Prior to the fourth quarter of 2012 (see additional details below), we did not recognize any favorable loss emergence. As a result, during some periods, we have recognized net adverse development for our liability insurance business in light of unfavorable loss emergence for certain reserving class and accident year combinations.
See 'Underwriting Results – Group, Prior Year Reserve Development' for further details on the recognition of adverse development for our long-tail business during the last three years.
Commencing with our fourth quarter 2012 reserving process, we began to give weight to actuarial methods that reflect our actual experience for liability business as we believed that our oldest accident years were at a stage of expected development where such methods would produce meaningful actuarial indications. In 2017, we continued to give weight to experience-based methods on the earlier years for the liability line of business leading to the recognition of some favorable experience on the reinsurance classes.

Sensitivity Analysis
While we believe that our loss reserves at December 31, 20172019 are adequate, new information, events or circumstances may result in ultimate losses that are materially greater or less than provided for in our loss reserves. As previously noted, there are many factors that may cause our reserves to increase or decrease, particularly those related to catastrophe losses and long-tail lines of business.

Our expectedExpected loss ratios are a key assumption in our estimateestimates of ultimate losses for business at an early stage of development. All else remaining equal, aA higher expected loss ratio would resultresults in a higher ultimate loss estimate, and vice versa. Our assumedAssumed loss development patterns are another significant assumption in estimating our loss reserves. All else remaining equal, acceleratingAccelerating a loss reporting pattern (i.e. shortening the claim tail) would resultresults in lower ultimate losses, as the estimated proportion of losses already incurred would be higher. The uncertainty in the timing of the emergence of claims (i.e. the length of the development pattern) is generally greater for a company like ours with a relatively limited operating history which, therefore, mustwe rely on industry benchmarks to a certain extent when establishing loss reserve estimates.
The following tables show the effect on our estimateestimates of gross loss reserves of reasonably likely changes in the two key assumptions used to estimate our gross loss reserves at December 31, 2017.2019 was as follows:

The results show the cumulative increase (decrease) in our loss reserves across all accident years. For example, if our assumed loss development pattern for ourinsurance property and other insurance business was three months shorter with no accompanying change in our ELR assumption, our loss reserves may decrease by approximately $87$70 million. Each of the impacts set forth in the tables is estimated individually, without consideration for any correlation among key assumptions or among reservingreserve classes. Therefore, it would be inappropriate to take each of the amounts and add them together in an attempt to estimate total volatility. While we believe the variations in the expected loss ratios and loss development patterns presented could be reasonably expected, our own historical loss data regarding variability is generally limited and actual


variations may be greater or less than these amounts. It is also important to note that the variations are not meant to be a "best-case" or "worst-case" series of scenarios and, therefore, it is possible that future variations in our loss reserves may be more or less than the amounts presented. While we believe that these are reasonably likely scenarios, we do not believe this sensitivity analysis should be considered an actual reserve range.

REINSURANCE RECOVERABLE
In the normal course of business, we purchase treaty and facultativereinsurance to protect our business from losses due to exposure aggregation andprotection to limit ultimate losses from catastrophic events. The purchase ofevents and to reduce loss aggregation risk. To the extent that reinsurers do not meet their obligations under the reinsurance does not discharge our liabilities under contracts written by us.agreements, we remain liable. Consequently, an exposure existswe are exposed to credit risk associated with respect to reinsurance recoverable balances to the extent that any of our reinsurers are unwillingunable or unableunwilling to pay our claims.
The following table shows the composition of our reinsurance recoverable on unpaid losses and loss expenses ("reinsurance recoverable") for each of ourthe reportable segments, segregated between thosereinsurance recoverable related to case reserves and thosereinsurance recoverable related to IBNR and by significant line of business:business was as follows:

The recognition of reinsurance recoverable on unpaid losses and loss expensesbalances requires two key estimates. The first estimate is the amount of losslosses reserves to be ceded to our reinsurers. This amount consists of two elements, thoseamounts related to our gross case reserves and thoseamounts related to our gross IBNR.
Reinsurance recoveriesrecoverable related to our gross case reserves areis estimated on a case-by-case basis by applying the terms of any applicable reinsurance coveragecover to our individual case reserve estimates. Our estimate of cededReinsurance recoverable related to IBNR is generally developed as part of our loss reserving process, and, consequently,therefore, its estimation is subject to similar risks and uncertainties as the estimation of gross IBNR. Estimates of amounts to be ceded under non-proportionalexcess of loss reinsurance contracts also take into account pricing information for those contracts and require greater judgment than estimates for proportional contracts.

The second estimate is the amount of the reinsurance recoverable on unpaid and paid lossesbalance that we willbelieve ultimately be unable to recover from reinsurers. The majority of our reinsurance recoverable on unpaid losses will not be due for collection until some pointcollected from reinsurers. We are selective in the future. Aschoosing reinsurers, buying reinsurance principally from reinsurers with a result, thestrong financial condition and industry ratings. The amount we ultimately collect may differ from our estimate due to the ability and willingness of reinsurers to pay our claims, which may be negatively impacted by factors such as insolvency, contractual


disputes over contract language or coverage and/or other reasons. Additionally, over the period of time before the amounts become due to us,In addition, economic conditions and/or operational performance of a particular reinsurer may deteriorate and this could also affect the willingnessability and abilitywillingness of a reinsurer to meet their contractual obligations to us. Accordingly,obligations.


Consequently, we review our reinsurance recoverable balances on a quarterly basis andto estimate and record an offsettinga provision for uncollectible amounts. Any changesadjustments to the provision for uncollectible amounts are recognized in this provisionthe period in which they are reflected in net income. We are selective in choosing our reinsurers, placing reinsurance principally with reinsurers with a strong financial condition and industry ratings.determined.
We apply case-specific provisions against certain recoveriesreinsurance recoverable balances that we deem unlikely to be collected in full. In addition, we use a default analysis to estimate oura provision for uncollectible amounts on the remainder of the reinsurance recoverable balance. The principal components of the default analysis are reinsurance recoverable balances by reinsurer and default factors applied to estimate uncollectible amounts based on our reinsurers’ credit ratings. The default factors are based on a model developed by a major rating agency. The
At December 31, 2019 and 2018, the provision recorded against reinsurance recoverablefor uncollectible amounts was $17$18 million and $20$21 million, at December 31,2017 and 2016, respectively. We have not written off any significant reinsurance recoverable balances in the last three years.

To the extent the creditworthiness of our reinsurers was to deterioratedeteriorates due to an adverse event affecting the reinsurance industry, such as a large number of major catastrophes, actual uncollectible amounts could be significantly greater than our provision.the provision for uncollectible amounts.

The decrease in 2017 compared to 2016 is due to a lower mix of proportional business associated with our recent acquisition of Novae. The increase in 2016 compared to 2015 was driven by an increase in the amount of proportional business written in our accident and health lines.
In our credit and political risk line of business, we write certain policies on a multi-year basis. We record premiumsPremiums in respect of these policies are recorded at the policy inception dateof the policy based on ourmanagement’s best estimate of total premiums to be received, including assumptions relating to prepayments/refinancings.

For example, when our exposure limitlimits for a contract isare reached, we fully earn any associated unearned premium.premiums are fully earned. This can have a significant impact on net premiums earned, particularly for multi-year contracts such as those in our credit and political risk line of business.

FAIR VALUE MEASUREMENTSFair Value Measurements of Financial Assets and Liabilities

Fair value is defined as the price to sell an asset or transfer a liability (i.e. the "exit price") in an orderly transaction between market participants. U.S. GAAP prescribes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data. The level in the hierarchy within which a given fair value measurement falls is determined based on the lowest level input that is significant to the measurement. The hierarchy is broken down into three levels as follows:
Level 1 – Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access. Valuation adjustments and block discounts are not applied to Level 1 instruments.


Level 2 – Valuations based on quoted prices in active markets for similar assets or liabilities, quoted prices for identical assets or liabilities in inactive markets, or for which significant inputs are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severities, etc.) or can be corroborated by observable market data.
Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The unobservable inputs reflect our own assumptionsjudgments about assumptions that market participants might use.
Refer to Item 8, Note 76 to the Consolidated Financial Statements 'Fair Value Measurements' for further detailsinformation on the valuation techniques including significant inputs and assumptions generally used in estimating the fair valuevalues of our financial instruments.

Our estimated fair value of a financial instrument may differ from the amount that could be realized if the security was sold in an immediate sale, e.g., a forced transaction. Additionally,In addition, the valuation of fixed maturitiesfinancial instruments is more subjective when markets are less liquid due to the lack of available market based inputs, as was the case during the global financial market crisis in late 2008 and early 2009. This may lead us to change the selection of our valuation technique (from market to incomecash flow approach) or may cause us to use multiple valuation techniques to estimate the fair value of a financial instrument. This circumstance may require significant management judgment and could cause ana financial instrument to be reclassified between levels of the fair value hierarchy.

Fixed Maturities and Equities

Equity Securities
At December 31, 2017,2019, the fair value for 93% (2016: 97%values of 95% (2018: 92%) of our total fixed maturities and equitiesequity securities was based on prices provided by globally recognized independent pricing services where we have a current and detailed understanding of how their prices were derived. The remaining securities were priced by either non-binding broker quotes or internal valuation models.

Generally, we obtain quotes directly from broker-dealers who are active in the corresponding markets when prices are unavailable from independent pricing services. This may also be the case if the pricing from pricing services is not reflective of current market levels, as detected by our pricing control tolerance procedures. Generally, broker-dealers value securities through their trading desks based on observable market inputs. Their pricing methodologies include mapping securities based


on trade data, bids or offers, observed spreads and performance on newly issued securities. They may also establish pricing through observing secondary trading of similar securities.
At December 31, 20172019 and 2016,2018, we have not adjusted any pricing provided by independent pricing services (see(refer to 'Management Pricing Validation' below). Additionally, ourIn addition, total Level 3 fixed maturities and equitiesequity securities amounted to $53$8 million (2016: $96(2018: $87 million), less than 1% of total fixed maturities and equities. Referequity securities (refer to Item 8, Note 76 to the Consolidated Financial Statements 'Fair Value Measurements'Measurements' for further information.information).
Management Pricing Validation
While we obtain pricing from pricing services and/or broker-dealers, management is ultimately responsible for determining the fair value measurements forof all securities. To ensure fair value measurement is applied consistently and in accordance with U.S. GAAP, we annually update our understanding of the pricing methodologies used by the pricing services and broker-dealers.
We also challenge any prices we believe may not be representative of fair value under current market conditions. Our review process includes, but is not limited to: (i) initial and ongoing evaluation of the pricing methodologies and valuation models used by outside parties to calculate fair value; (ii) quantitative analysis; (iii) a review of multiple quotes obtained in the pricing process and the range of resulting fair values for each security, if available, and (iv) randomly selecting purchased or sold securities and comparing the executed prices to the fair value estimates provided by the independent pricing sources and broker-dealers.

CLO-Equity Securities
We have alsoAt December 31, 2019 and 2018, we had invested directly and indirectly, (throughthrough a fund structure)structure in CLO-Equities, also known as "cash flow CLOs" in the industry. During 2017,2019, the CLO-Equity market continued to be relatively inactive with only a small number of transactions being observed, particularly as it related to transactions involving our CLO-Equities. Given that all of our direct investmentsOur indirect investment in CLO-Equities are past their reinvestment period, there is uncertainty over the remaining time until maturity. As such, fair values of our direct investments in CLO-Equities are estimated using a liquidation valuation. Our indirect investments in CLO-Equities are valued using a discounted cash flow model prepared by an external manager with similar inputs as our internally developed discounted cash flow model.manager. At December 31, 2017,2019 and 2018, the estimated fair value forof our indirect investment in CLO-Equities was $31$14 million (2016: $61(2018: $21 million).

Other Privately Held Investments

Other privately held securitiesinvestments include convertible preferred shares, common shares, convertible notes and notes payable. These securities are initially valued at cost which approximates fair value. In subsequent measurement periods, the fair values of these securitiesinvestments are generally determined using capital statements obtained from each investee. In 2018, the fair values of some of these investments were determined using an internally developed discounted cash flow model.

As the significant inputs used to price the underlying investments are observable market inputs, the fair values of overseas deposits are classified as Level 2.

OTHER-THAN-TEMPORARY IMPAIRMENTSOther-Than-Temporary Impairments ("OTTI")
Our available-for-sale ("AFS") investment portfolioA fixed maturity is impaired if the largest component of our consolidated assets and it is a multiple of our shareholders’ equity. As a result, an OTTI charge could be material to our financial condition and operating results particularly during periods of dislocation in financial markets. During 2017, we recorded an OTTI charge in net income of $14 million (2016: $26 million; 2015: $73 million). Refer to the 'Net Investment Income and Net Realized Investment Gains (Losses)' section above for further details.
A security is "impaired" if fair value of the investment is below amortized cost for fixed maturities or cost for equities. cost.
On a quarterly basis, we review all impaired AFS securities to determine if impairments are other-than-temporary. The OTTI assessment is inherently judgmental, especially wherewhen securities have experienced severe declines in fair value over a short period. Our impairment review process begins with a quantitative analysis to identify securities to be further evaluated for potential OTTI. For all identified securities, further fundamental analysis is performed that considers the following quantitative and qualitative factors:
 
a.Thethe length of time and extent to which the fair value has beenis less than the amortized cost for fixed maturities or cost for equity securities.cost.
b.Thethe financial condition, near-term and long-term prospects for the issuer of the security, including relevant industry conditions and trends, and the implications of rating agency actions, and offering prices.

Our available for sale ("AFS") investment portfolio is the largest component of consolidated total assets and it is a multiple of shareholders’ equity. As a result, an OTTI charge could be material to our financial condition and operating results particularly during periods of dislocation in financial markets.
If a fixed maturity is impaired and we intend to sell the entiresecurity or it is more likely than not that we will be required to sell the security before its anticipated recovery, the impairment is considered other-than-temporary. In these instances, the full amount of the impairment (i.e. the difference between the security’s fair value and its amortized cost) is charged to net income and is included in net investment gains (losses) in the consolidated statements of operations.
In instances where we intend to hold the impaired fixed maturity, and we do not anticipate to fully recover the amortized cost andbased on projected cash flows to be collected from the full amountsecurity (i.e. a credit loss exists), the credit loss component of the impairment is charged to net income and is included in net realized investment gains (losses). If in the impairment arises due toconsolidated statements of operations. On recognition of an anticipated credit loss onOTTI charge, the new cost basis for the security (third criterion above), we recognize onlyis the credit loss component (i.e.amortized cost basis less the amount representingOTTI charge recognized in net income. The new cost basis is not adjusted for subsequent increases in fair value. The difference between the decrease innew cost basis and the cash flows expected to be collected)collected is accreted or amortized on a quarterly basis to net


investment income over the remaining life of the OTTI charge in net income with a corresponding adjustment to amortized cost (new cost basis) of the security.fixed maturity. The non-credit component (e.g. interest rates, market conditions, etc.) of the OTTI charge is recognized in other comprehensive income in shareholders’ equity.income.
From time to time, we may sell fixed maturities subsequent to the balance sheet date that we did not intend to sell at the balance sheet date. Conversely, we may not sell fixed maturities that we previously intended to sell at the balance sheet date. SuchThese changes in intent may arise due to events occurring subsequent to the balance sheet date. The types of events that may result in a change in intent include, but are not limited to, significant changes in the economic facts and circumstances related to the specific issuer, changes in liquidity needs, or changes in tax laws or the regulatory environment.


For impaired investment-grade securities (i.e. rated BBB- or above) that we do not intend to sell and it is more likely than not that we will not be required to sell, we have established some parameters for identifying securities with potential credit losses.
Our parameters focus primarily on the extentduration and durationthe extent of the decline, including but not limited to:
declines in value greater than 20% for nine consecutive months, and
declines in value greater than 10% for twelve consecutive months.
For impaired securities held withinin our high yield portfolios (i.e. managed under a mandatethat we do not intend to invest primarily in non-investment grade securities),sell and it is more likely than not that we will not be required to sell, we have established separate parameters for our credit loss assessment. Due to the additional volatility inherent in high yield securities relative to investment-grade securities, we focus on the severity of the impairment and work closely with our external high yield investment managers to identify securities with significant potential credit losses.
If a security meets one of the above parameters, we then perform a fundamental analysis that considers the quantitative and qualitative factors noted in a. through d. above to determine whether an impairment charge should be recognized in the period under review.
Our OTTIcredit impairment review process for credit impairment excludes all fixed maturities guaranteed, either explicitly or implicitly, by the U.S. government and its agencies (U.S. Government, U.S. Agency and U.S. Agency RMBS) because we anticipate these securities will not be settled below amortized costs. However, thesecost. These securities are still evaluated for intention to sell at a loss.

The credit loss component of an OTTI charge recognized in net income is calculated based on the difference between the amortized cost of the security and the net present value of its projected future cash flows discounted atexpected to be collected from the effective interest rate implicit in the debt security prior to the impairment.security. The significant inputs and the methodology used to estimate credit losses are disclosed in Item 8, Note 65 (f) to the Consolidated Financial Statements 'Investments'.
Equities
We consider our ability and intent to hold an equity security in an unrealized loss position for a reasonable period of time to allow for a full recovery. As an equity security does not have a maturity date, the forecasted recovery for an equity security is inherently more judgmental than for a fixed maturity security.
In light of the volatility of global equity markets we have experienced in recent years, we generally impair equities for which we do not forecast a recovery to cost within two years. Further, we generally impair an equity security if its fair value is 15% below its cost. We have also established parameters for identifying potential impaired equity securities for fundamental analysis based on the severity, in either percentage or absolute dollar terms, of the unrealized loss position.
From time to time, we may sell our AFS equities subsequent to the balance sheet date that were considered temporarily impaired at the balance sheet date. This may occur due to events occurring subsequent to the balance sheet date that result in a change in our intent or ability to hold an equity security. Such subsequent events that may result in a sale include significant deterioration in the financial condition of the issuer, significant unforeseen changes in our liquidity needs, or changes in tax laws or the regulatory environment.

OFF-BALANCE SHEET AND SPECIAL PURPOSE ENTITY ARRANGEMENTS

At December 31, 20172019, we arewere not party to any off-balance sheet arrangements, as defined by Item 303(a)(4) of Regulation S-K to which an entity unconsolidated with usthe Company is a party that management believes is reasonably likely to have a current or future effect on its financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that we believe is material to investors.



ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Market risk represents the potential for an economic loss due to adverse changes in the fair valuevalues of financial instruments. Referinstruments (refer to Item 1 Risk'Risk and Capital Management’Management' for further details on how we manage market risk relating to our financial instruments.details).
We own a substantial amount of assets whose fair values are subject to market risks. Our fixed maturities and equity securities are classified as available-for-sale and, as such,available for sale, therefore changes in fair valuevalues caused by changes in interest rates equity prices and foreign currency exchange rates will have an immediate impact on our comprehensive income, shareholders’ equity and book value but may not have an immediate impact on consolidated net income. Changes in these market risks will only impact our consolidated net income when, and if, securities are sold or an OTTI charge is


recorded. Further,Equity securities are reported at fair value, with changes in fair values recognized in net income. At December 31, 2019 and 2018, we havealso invested in alternative investments including hedge funds, direct lending funds, private equity funds, real estate funds, CLO-Equities, and other privately held investments at December 31, 2017and 2016.overseas deposits. These investments are also exposed to market risks, with the changechanges in fair valuevalues immediately reported immediately in earnings.net income.
Sensitivity Analysis
The following is a sensitivity analysis of our primary market risk exposures at December 31, 20172019 and 2016. 2018.
Our policies to address these risks in 20172019 were not materially different from 2016.2018. We do not currently anticipate significant changes in our primary market risk exposures or in how those exposures are managed in future reporting periods based uponon what is known or expected to be in effect in future reporting periods.
SENSITIVITY ANALYSIS
Interest Rate and Credit Spread Risk
Interest rate risk includes fluctuations in interest rates and credit spreads that have a direct impact on the fair valuevalues of our fixed maturities. As interest rates rise and credit spreads widen, the fair value of fixed maturities falls, and the converse is also true.
We monitor our sensitivity to interest rate and credit spread changes by revaluing our fixed maturities using a variety of different interest rates (inclusive of credit spreads). We use duration and convexity at the security level to estimate the change in fair value that would result from a change in each security’s yield. Duration measures the price sensitivity of an asset to changes in yield rates. Convexity measures how the duration of the security changes with interest rates. The duration and convexity analysis take into account changes in prepayment expectations for MBS and ABS securities.ABS. The analysis is performed at the security level and aggregated up to the asset category levels for reporting in the tables below.levels.




The following table presents the estimated pre-tax impact on the fair value of our fixed maturities at December 31, 2017 and 2016 due to an instantaneous increase in the U.S. yield curve of 100 basis points and an additional 100 basis point credit spread widening for corporate debt, non-agency residential and commercial MBS, ABS and municipal bond securities.

U.S. government agencies have a limited range of spread widening, therefore, 100 basis points of spread widening for these securities is highly improbable in normal market conditions. Our non-U.S. government debt obligations are highly-rated and we believe the potential for future widening of credit spreads would also be limited for these securities. Further, certainCertain of our holdings in non-agency RMBS and ABS have floating interest rates, which mitigate our interest rate risk exposure.
The above sensitivity analysis reflects our view of changes that are reasonably possible over a one-year period. Note this should not be construed as our prediction of future market events, but rather an illustration of the impact of such events.
Our investment in CLO-Equities is also exposed to interest rate risk, but itan increase in the risk free yield curve of 100 basis points would have an insignificant impact to its fair value in the event the risk free yield curve increase by 100 basis points.value.


Additionally,In addition, our investment in bond mutual funds is exposed to interest rate risk;risk, however, this exposure is largely mitigated by the short duration of the underlying securities.
Equity Price Risk
Our portfolio of equity securities, excluding the bond mutual funds, has exposure to equity price risk. This risk is defined as the potential loss in fair value resulting from adverse changes in stock prices. The global equity portfolio is managed to a benchmark composite index, which consists of a blend of the S&P 500 and MSCI World indices. Changes in the underlying indices have a corresponding impact on the overall portfolio. TheAt December 31, 2019, the fair value of our equity securities at December 31, 2017 was $453


$298 million (2016: $515(2018: $237 million). At December 31, 2017,2019, the impact of a 20% decline in the overall market prices of our equity exposures would be $91$60 million (20162018: $103 million)$47 million), on a pre-tax basis.
Our investment in hedge funds has significant exposure to equity strategies with net long positions. At December 31, 20172019, the impact of an instantaneous 15% decline in the fair value of our investment in hedge funds would be $5525 million (20162018: $75 million)$29 million), on a pre-tax basis.

Net Managed Foreign Currency Exposure
Our net managed foreign currency exposure is subject to our internal risk tolerance standards. For significant foreign currency exposures, defined as those where our net asset/liability position exceeds the greater of 1% of our shareholders' equity or $50$55 million, the value of assets denominated in those currencies should fall within a range of 90 - 110% of liabilities denominated in the same currency. In addition, our aggregate foreign currency exposure is subject to the same tolerance range. We may use derivative instruments to maintain net managed foreign currency exposures within our risk tolerance levels.

Other Net Foreign Currency Exposure
Other net foreign currency exposure includes those assets managed by specific investment managers who have the discretion to hold foreign currency exposures as part of their total return strategy. At December 31, 2017,2019, other net foreign currency exposure primarily consisted of our emerging market debt securities portfolio and euro-denominated exchange traded funds.  For further details on these portfolios refer(refer to the Item 7 'Management’s'Management’s Discussion and Analysis of Financial Condition and Results of Operations – Cash and Investments' for further details).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of AXIS Capital Holdings Limited


Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of AXIS Capital Holdings Limited and subsidiaries (the "Company") as of December 31, 20172019 and 2016,2018, the related consolidated statements of operations, comprehensive income, changes in shareholders' equity, and cash flows, for each of the three years in the period ended December 31, 2017,2019, and the related notes and the schedules listed in the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20172019 and 2016,2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017,2019, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017,2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 28, 201827, 2020 expressed an unqualified opinion on the Company's internal control over financial reporting.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Reserve for losses and loss expenses - Refer to Notes 2 and 8 to the consolidated financial statements
Critical Audit Matter Description
The Company’s estimate of loss and loss expense reserves is derived using expected trends in claim severity and frequency and other factors that may vary significantly as claims are settled. The estimate is sensitive to significant assumptions, including the initial expected loss ratio and loss development factors. The estimate is also sensitive to the selection of actuarial methods and weighting of these methods applied to project the ultimate losses, the estimation of ultimate reserves associated with catastrophic events, and other factors. Further, not all catastrophic events can be modeled using traditional actuarial methodologies, which increases the degree of judgment needed in estimating loss reserves for such events.
Auditing the Company’s methods, assumptions and best estimate of the cost of the ultimate settlement and administration of claims represented by the incurred but not reported ("IBNR") claims included in recorded loss and loss adjustment reserves involved especially subjective auditor judgment and an increased extent of effort, including the involvement of our actuarial specialists.


How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to reserves for losses and loss expenses included the following, among others:
We tested the effectiveness of controls over the valuation of the recorded loss and loss expense reserves, including the review and approval process that management has in place for significant actuarial methods and assumptions used and the approval of management’s best estimate of loss and loss expense reserves.
We tested the completeness and accuracy of the underlying data that served as the basis for the Company’s actuarial analysis, including historical claims data, to test the reasonableness of key inputs to the actuarial estimate.
With the assistance of our actuarial specialists:
We independently developed an estimate of the reserves for selected classes of business, compared our estimates to those booked by the Company, and evaluated the differences.
We evaluated the Company’s methodologies against recognized actuarial practices for the remaining classes. We also evaluated the assumptions used by the Company using our industry knowledge and experience and other analytical procedures.
We compared the results of the reserve study prepared by third party actuaries to management’s best estimate and evaluated the differences.

2.BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)



The Company's significant accounting policies are as follows:

a)Investments
InvestmentsFixed Maturities, Available-for-sale, at Fair Value
Fixed maturities classified as available for sale
Fixed maturities and equity securities classified as "available for sale" are reported at fair value at the balance sheet date (see(refer to Note 76 'Fair Value Measurements'). The change in fair value (net unrealized gain (loss)) on available for sale investments,values of fixed maturities, net of tax is included as a separate component ofrecognized in accumulated other comprehensive income (loss) ("AOCI") in the consolidated statement of changes in shareholders’ equity.
Net investment income includes interest and dividend income and the amortization of market premiums and discounts and is presented net of investment expenses. Investment income is recognized when earned. Purchases and sales of investmentsfixed maturities are recorded on a trade-date basis and realized investment gains (losses) on sales of investmentsfixed maturities are determined based on the specific identification method. Realized investment gains (losses) on fixed maturities are included in net investment gains (losses) in the consolidated statements of operations.
The Company recognizes investment income from fixed maturities based on the constant effective yield method, which includes an adjustment for estimated principal repayments, if any.applicable. The effective yield used to determine the amortization forof fixed maturities subject to prepayment risk (e.g. asset-backed, loan-backedmortgage-backed and other structured securities) is recalculated and adjusted periodically based upon actualon historical and/or projected future cash flows. The adjustmentsAdjustments to the yield for highly-ratedhighly rated prepayable fixed maturities are accounted for using the retrospective method. The adjustmentsAdjustments to the yield for other prepayable fixed maturities are accounted for using the prospective method.
On a quarterly basis, the Company assesses whether unrealized losses on available for sale investments represent impairments that are other than temporary. Several factors are considered in this assessment including, but not limited to:

(i) the extent and duration of the decline;
(ii) the reason for the decline (e.g. credit spread widening, credit event, foreign exchange rate movements);
(iii) the historical and implied future volatility of the fair value;
(iv) the financial condition and near-term prospects of the issuer; and
(v) the collateral structure and credit support of the security, if applicable.
A fixed maturity is impaired if the fair value of the investment is below amortized cost. On a quarterly basis, the Company assesses whether unrealized losses on fixed maturities represent impairments that are other-than-temporary. The Company's impairment review process begins with a quantitative analysis to identify securities to be evaluated for potential OTTI. For identified securities, fundamental analysis is performed that considers the following quantitative and qualitative factors:
a.the duration and the extent of the decline;         
b.the financial condition, near-term and long-term prospects of the issuer of the security;
c.the reason for the decline (e.g. credit spread widening, credit event, foreign exchange rate movements);
d.the historical and implied future volatility of the fair value; and 
e.the collateral structure and credit support of the security, if applicable.
If a fixed maturity is impaired additional analysis is performed to determine whether the impairment is temporary or other-than-temporary. For an impaired fixed maturity whereand the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before its anticipated recovery, the impairment is considered other than temporary. Theother-than-temporary. In these instances, the full amount of the impairment is charged to net income and is included in net realized investment gains (losses). in the consolidated statements of operations.
In instances where the Company intends to hold the impaired fixed maturity, the Company estimates the anticipated credit loss ofon the security and recognizes only this portioncomponent of the impairment is charged to net income and is included in net investment gains (losses) in the consolidated statements of operations. On recognition of an OTTI charge, the new cost basis for the security is the amortized cost basis less the OTTI charge recognized in net income. The new cost basis is not adjusted for subsequent increases in fair value. The difference between the new cost basis and the cash flows expected to be collected is accreted or amortized on a quarterly basis to net investment income withover the remaining life of the fixed maturity.
The Company recognizes the non-credit related balancecomponent of the impairment (i.e. related to interest rates, market conditions, etc.) in other comprehensive income.

d)Losses and Loss Expenses
Reserve for losses and loss expenses represents an estimate of the unpaid portion of the ultimate liability for losses and loss expenses for (re)insured and reinsured events that have occurred at or before the balance sheet date. The balance reflects bothThese amounts reflect claims that have been reported ("case reserves") and claims that have been incurred but have not yet been reported ("IBNR"). These amounts and are reduced for estimated amounts of salvage and subrogation recoveries.
The Company reviews its reserve for losses and loss expenses on a quarterly basis. Case reserves are primarily established based on amounts reported fromby insureds and/or their brokers. Management estimates IBNR after reviewing detailed actuarial analyses and applying informed judgment regarding qualitative factors that may not be fully captured in the actuarial estimates. A variety of actuarial methods are utilized in this process, including the Expected Loss Ratio, Bornhuetter-FergusonChain Ladder and Chain LadderBornhuetter Ferguson methods. The estimate is highly dependent on management’s judgment as to which method(s) are most appropriate for a particular accidentaccident/underwriting year and classline of business. Historical claims data is often supplemented with industry benchmarks when applying these methodologies.
Any adjustments to previous reserve for losses and loss expenses estimates are recognized in the period in which they are determined. While the Company believes that its reserves for losses and loss expenses are adequate, this estimate requires significant judgment and new information, events or circumstances may result in ultimate losses that are materially greater or less than provided for in the Consolidated Balance Sheets.

Retroactive Reinsurance

Retroactive reinsurance reimburses a ceding company for liabilities incurred as a result of past insurable events covered under contracts subject to the reinsurance. In certain instances, reinsurance contracts cover losses both on a prospective basis and on a retroactive basis and where practical the Company bifurcates the prospective and retrospective elements of these reinsurance contracts and accounts for each element separately. Initial gains in connection with retroactive reinsurance contracts are deferred and amortized into income over the settlement period while losses are recognized immediately. When changes in the estimated amount recoverable from the reinsurer or in the timing of receipts related to that amount occur, a cumulative amortization adjustment is recognized in earningsnet income in the period ofin which the change is determined so that the

f)Foreign Exchange
The functional currency of the Company and the majority of its subsidiaries is the U.S. dollar. All foreign currency transactions are initially measured and recorded in functional currency using the rates of exchange prevailing at the transaction date.
Monetary assets and liabilities denominated in foreign currency are remeasured to functional currency at the rates of exchange in effect at the balance sheet date with the resulting foreign exchange losses (gains) generally being recognized in the consolidated statements of operations. Foreign exchange losses (gains) related to available for sale investments denominated in foreign currency represent an unrealized appreciation (depreciation) in the market value of the securities and are included in AOCI. Non-monetary assets and liabilities denominated in foreign currency are not subsequently remeasured.

In recording foreign currency transactions, revenue and expense items are converted to the relevant functional currency at the exchange rate prevailing at the transaction date. Assets and liabilities originating in currencies other than the functional currency are remeasured to the functional currency at the rates of exchange in effect at the balance sheet date. The resulting foreign currency gains or losses are recognized in the Consolidated Statements of Operations, with the exception of those related to foreign-denominated available for sale investments. For these investments, exchange rate fluctuations represent an unrealized appreciation/depreciation in the value of the securities and are included in the related component of AOCI.

i)Goodwill and Intangible Assets
The Company recognizes goodwill and other intangible assets in connection with certain acquisitions. Goodwill represents the excess of the purchase price paid over the fair value of the net assets acquired in these acquisitionacquisitions and is not amortized. Other intangible assets with a finite life are amortized over the estimated useful live of the intangible asset. Other intangible assets with an indefinite life are not amortized.

The Company tests goodwill and indefinite intangible assets for potential impairment during the fourth quarter each year and between annual tests if an event occurs or changes in circumstances indicate that the asset is impaired. Such events or circumstances may include an economic downturn in a geographic market or a change in the assessment of future operations.

For the purposespurpose of evaluating goodwill for impairment, the Company may first perform a qualitative assessment , to determine whether it is necessary to perform the two-stepa quantitative goodwill impairment test. If determined to be necessary, the two-step impairmentquantitative test is used to identify potential goodwill impairment and measure the amount of a goodwill impairment loss to be recognized, if any. The first step of the goodwill impairment test, used to identify potential impairment, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired and the second step of the impairment test is unnecessary.impaired. If the carrying amount of athe reporting unit exceeds itsthe fair value, an impairment loss is recognized in an amount equal to that excess, limited to the second step of the goodwill impairment test shall be performed to measure thetotal amount of impairment loss, if any. The second step of the goodwill impairment test compares the implied fair value ofallocated to that reporting unit goodwill with the carrying amount of that goodwill.

unit.
For the purposespurpose of evaluating indefinite lived intangibles for impairment, the Company may first perform a qualitative assessment to determine whether it is necessary to perform the quantitative impairment test. If the Company elects to perform a qualitative assessment, it first assesses qualitative factors to determine whether it is more likely than not that an indefinite lived intangible asset is impaired. If the Company determines that it is not more likely than not that the indefinite lived intangible asset is impaired, the Company does not calculate the fair value of the intangible asset and performperforms the quantitative impairment test.

For the purposes of evaluating goodwill and indefinite lived intangible assets for impairment, the Company has an unconditional option to bypass the qualitative assessment in any period and proceed directly to performing the quantitative impairment test. The Company may resume performing the qualitative assessment in any subsequent period.

For other definite lived intangible asset the Company tests for recoverability whenever events or changes in circumstances indicate its carrying amount may not be recoverable. The Company recognizes an impairment loss if the carrying amount of

the asset is not recoverable and exceeds its fair value. The carrying amount of a definite lived intangible asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset.

If goodwill or an intangible asset is impaired, the carrying value of the asset is reduced to fair value and a corresponding expense is recorded in the Consolidated Statementsconsolidated statements of Operations.operations.

j)    Income Taxes
 j)Income Taxes
Certain subsidiaries and branches of the Company operate in jurisdictions where they are subject to taxation. Current and deferred income taxes are charged or credited to net income, or in certain cases to AOCI, based uponon enacted tax laws and rates applicable in the relevant jurisdiction in the period in which the tax becomes accruable or realizable. Deferred income taxes are provided for all temporary differences between the bases of assets and liabilities used in the Consolidated Balance Sheetsconsolidated balance sheets and those used in the various jurisdictional tax returns. When the assessment indicates that it is more likely than not that a portion of a deferred tax asset will not be realized in the foreseeable future, a valuation allowance against deferred tax assets is recorded. The Company recognizes the tax benefits of uncertain tax positions only when the position is more-likely-than-not to be sustained uponon audit by the relevant taxing authorities.

Stock Compensation - Improvements to Employee Share-Based Payment Accounting

Effective January 1, 2017,2019, the Company adopted Accounting Standards Update ("ASU" ) ASU 2016-09, "Compensation - Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting" which simplifies several aspects of the accounting for share-based payments to employees including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance requires all excess tax benefits and tax deficiencies to be recognized in the income statement with the tax effects of exercised or vested awards to be treated as discrete items in the reporting period in which they occur. Excess tax benefits should be classified along with other income tax cash flows as an operating activity on the statement of cash flows. In addition, companies are required to make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. The guidance allows withholding up to the maximum statutory tax rates in the applicable jurisdictions to cover income taxes on share-based compensation awards without requiring liability classification. Cash paid by an employer when directly withholding shares for tax withholding purposes should be classified as a financing activity. Cash paid by the Company by directly withholding shares for tax withholding purposes is included in taxes paid on withholding shares in the Consolidated Statement of Cash Flows. To facilitate comparison of information with prior year amounts, the corresponding amounts for the years ended December 31, 2016 and 2015 have been reclassified to conform to the current year's presentation. The adoption of this guidance did not have a material impact on the Company's results of operations, financial condition and liquidity.

Revenue From Contracts With Customers

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)". This guidance affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB delayed the effective date by one year through the issuance of ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date". This guidance is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2016. Accounting for insurance contracts is not within the scope of ASU 2014-09. The Company generates an insignificant amount of fee income, primarily from strategic capital partners, which is reported in other insurance related income (losses) in the Consolidated Statements of Operations and is within the scope of ASU 2014-09. The Company's current accounting policy to recognize fee income when the related services have been performed is consistent with the guidance in this ASU. As a result, the Company does not expect the adoption of this guidance to have a material impact on its results of operations, financial condition and liquidity.

Recognition and Measurement of Financial Assets and Financial Liabilities

In January 2016, the FASB issued ASU 2016-01 "Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities" which requires:

equity investments (except those accounted for under the equity method of accounting, investments that are consolidated or those that meet a practicability exception) to be measured at fair value with changes in fair value recognized in net income,
simplifies the impairment assessment of equity investments without readily determinable values by requiring a qualitative assessment to identify impairment, eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost,
requires the use of the exit price notion when measuring the fair value of financial instruments for disclosure purposes,
requires separate presentation in other comprehensive income of the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the organization has elected to measure the liabilities in accordance with the fair value option,
requires the separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; and
clarifies that the reporting organization should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the organization’s other deferred tax assets.

This guidance is effective for interim and annual reporting periods beginning after December 15, 2017 with early adoption permitted for certain of the amendments. The adoption of this guidance is expected to have a material impact on the Company's results of operations as changes in fair value of equity securities will be included in net income rather than other comprehensive income. At December 31, 2017, accumulated other comprehensive income included $70 million of net unrealized gains on equity securities, net of taxes.

Leases

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)," which provides a new comprehensive model for lease accounting. The guidance will requireTopic 842 requires a lessee to recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. ThisThe adoption of this standard resulted in the recognition of lease liabilities and right-of-use assets of $150 million in the Company's consolidated balance sheet at January 1, 2019, which are related to office property and equipment leases.
In addition, the Company adopted ASU 2018-11, "Leases (Topic 842) - Targeted Improvements," which provides an additional (and optional) transition method to adopt the new lease guidance. Under the alternative transition method, the Company's reporting for the comparative periods presented in its financial statements will be in accordance with the pre-effective date lease accounting requirements (Topic 840).
The Company also elected the package of practical expedients permitted under the transition guidance is effective forof Topic 842, which were elected as a package and applied consistently to all leases. At the adoption date, the package of practical expedients permitted the Company to not reassess the following:

3.initial direct costs for any existing leases.
In addition to electing the package of practical expedients, the Company made an accounting policy election to account for non-lease components separately from lease components. As a result, the non-lease components associated with the Company's leases are not included in the lease liabilities and right-of-use assets in the Company's consolidated balance sheet at December 31, 2019.

Measurement of Credit Losses on Financial Instrument

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments" which replaces the "incurred loss" impairment methodology with an approach based on "expected losses" to estimate credit losses on certain types of financial instruments and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance requires financial assets measured at amortized cost to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses. The guidance also provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. This guidance is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted for interim and annual periods beginning after December 15, 2018. The Company is currently evaluating the impact of this guidance on its results of operations, financial condition and liquidity.

Classification of Certain Cash Receipts and Cash Payments

In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments" which addresses diversity in practice in how eight specific cash receipts and cash payments should be presented and classified on the statement of cash flows. This guidance is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. As this guidance relates solely to financial statement disclosures, the adoption of ASU 2016-18, will not impact the Company's results of operations, financial condition and liquidity.

Restricted Cash

In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230) - Restricted Cash" which addresses diversity in practice in the classification and presentation of changes in restricted cash on the statement of cash flows. This guidance will require a statement of cash flows to explain the change during the period in the total of cash, cash equivalents, restricted cash and restricted cash equivalents. Transfers between cash and cash equivalents and restricted cash and restricted cash equivalents will no longer be presented on the statement of cash flows. This guidance is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The guidance will be adopted on a retrospective basis. As this guidance relates solely to financial statement disclosures, the adoption of ASU 2016-18, will not impact the Company's results of operations, financial condition and liquidity.

Simplifying the Test for Goodwill Impairment

In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment" that eliminates the requirement to calculate the implied fair value of goodwill (i.e., Step 2 of the current goodwill impairment test) to measure a goodwill impairment charge. Instead, an impairment charge will be based on the excess of a reporting unit's carrying amount over its fair value (i.e., measure the charge based on Step 1 of the current goodwill impairment test). This guidance is effective for annual and interim impairment tests performed in periods beginning after December 15, 2019, with early adoption permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The guidance will be adopted on a prospective basis.

Measurement of Credit Losses on Financial Instrument
In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments," which replaces the "incurred loss" impairment methodology with an approach based on "expected losses" to estimate credit losses on certain types of financial instruments and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company's mortgage loans, held for investment, insurance and reinsurance premium balances receivable and its reinsurance recoverables on unpaid and paid losses and loss expenses are its more significant financial assets within the scope of ASU 2016-13. The guidance requires financial assets to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the cost of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset.

Stock Compensation - Scope of Modification Accounting

In May 2017, the FASB issued ASU 2017-09 "Compensation - Stock Compensation (Topic 718) - Scope of Modification Accounting" to provide clarity and reduce diversity in practice of applying the guidance in Topic 718 to a change to the terms or conditions of a share-based payment award. This ASU provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The guidance states that an entity should account for the effects of a modification unless all the following are met:

1.the fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified;
2.the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and
3.the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified.

The current disclosure requirements in Topic 718 apply regardless of whether an entity is required to apply modification accounting under the amendments in this Update. This guidance is effective for interim and annual reporting periods, beginning after December 15, 2017, with early adoption permitted. The Company anticipates adopting this guidance effective January 1, 2018. The adoption of this guidance will not materially impact the Company's results of operations, financial condition or liquidity.

Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income

In February 2018, the FASB issued ASU 2018-02 "Income Statement - Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" in response to a financial reporting issue that arose as a consequence of the U.S. federal government tax bill, H.R.1, An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018 ("U.S. Tax Reform") which was enacted on December 22, 2017.

U.S. GAAP currently requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date. This guidance is applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income rather than in income from continuing operations. As the adjustment of deferred taxes due to the reduction of the historical corporate income tax rate to the newly enacted corporate income tax rate is required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income (referred to as stranded tax effects for purposes of this Update) do not reflect the appropriate tax rate.

The amendments in this Update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from U.S. Tax Reform. Consequently, the amendments eliminate the stranded tax effects resulting from U.S. Tax Reform and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of U.S. Tax Reform, the

underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected.

This guidance is effective for interim and annual reporting periods, beginning after December 15, 2018, with early adoption permitted. The Company anticipates adopting this guidance effective January 1, 2018. As a consequence of U.S. Tax Reform, the Company recognized a tax benefit of $2 million related to the revaluation of net deferred tax liabilities associated with the reduction in the U.S. corporate income tax rate from 35% to 21%, attributable to net unrealized investment gains associated with investment held by the Company's U.S domiciled entities. The adoption of this guidance will not materially impact the Company's results of operations, financial condition or liquidity.

a)Acquisition of Novae Group plc

On October 2, 2017 (the "closing date" or the "acquisition date"), AXIS Specialty UK Holdings Limited, a wholly owned subsidiary of the Company, acquired a 100% ownership interest in Novae Group plc ("Novae") for an aggregate purchase price of $617 million. Novae is a diversified property and casualty (re)insurance business operating through Syndicate 2007 at Lloyd’s. The results of Novae are included in the results of the Company's insurance and reinsurance segments from that date. The acquisition of Novae was undertaken to accelerate the growth strategy of the Company's international insurance business, and to significantly scale up its capabilities to enable the Company to even better serve its clients and brokers.

In connection with the acquisition of Novae, the Company incurred transaction and reorganization related expenses of $27 million in the year ended December 31, 2017, which included transaction costs, such as due diligence, legal, accounting, investment banking fees and expenses, as well as integration expenses related to the integration of Novae into the Company's operations and compensation-related costs associated with the termination of certain employees.

The purchase price was allocated to the assets acquired and liabilities assumed of Novae based on estimated fair values at the closing date and the Company recognized goodwill of $54 million.

The allocation of the purchase price is based on information included in Novae's audited financial statements at October 2, 2017. The allocation is subject to change if additional information becomes available within the measurement period, which cannot exceed 12 months from the acquisition date. The fair values of the assets acquired and liabilities assumed may be subject to adjustments, which may impact the amounts recorded for the assets acquired and liabilities assumed as well as the goodwill.

The Company identified finite lived intangible assets of $385 million, including Value of Business Acquired ("VOBA") which represents the present value of the expected underwriting profit within policies that were in-force at the closing date of the transaction, of $257 million and finite lived intangible assets primarily related to distribution networks of $128 million. Finite lived intangible assets will be amortized over a weighted average period of 7 years. The Company also identified indefinite lived intangible assets related to Lloyd's syndicate capacity of $95 million.

Valuation methodologies applicable to identifiable intangible assets are explained as follows:

Lloyd's syndicate capacity: Lloyd's syndicate capacity was valued using the Multi-Period Excess Earnings Method, an application of the Income Approach. Key inputs used in the valuation model used for this intangible asset included projected pre-tax operating profit attributable to syndicate capacity, contributory asset charges which represent the required return on and of intangibles assets utilized to generate future revenue and operating income, and an appropriate discount rate.

Distribution network: Distribution network including coverholders, large broker and SME brokers was valued using the Distributor Method, an application of the Income Approach. Key inputs used in the valuation model used for this intangible asset included net premiums earned attributable to existing distributors, attrition rates, profit margins, projected pre-tax operating profit attributable to existing distributors, contributory asset charges which represent the required return on and of intangibles assets utilized to generate future revenue and operating income, and an appropriate discount rate.

VOBA: VOBA was computed as the difference between the fair value of unearned obligations and the unearned premiums reserve recorded by Novae at the acquisition date. Key inputs used in the valuation model used for this intangible asset included the fair value of the unearned premium computed as the present value of future unearned cash flows, plus the present value of the costs associated with holding capital to support these exposures together with the fair value of reserves computed as the present value of future net losses and loss expense payments, plus the present value of the costs associated with holding capital to support those payments.

(1)During the year ended December 31,
Acquisitions in 2017 an amount of $6,136 and 7,945 was adjusted from gross amount and accumulated amortization, respectively, as a result of the wind-down of the Company's retail insurance operations in Australia.

On April 1, 2015, the Company completed the acquisition of Ternian Insurance Group LLC ("Ternian"), a leading provider of voluntary, limited benefit affordable health plans and other employee benefits coverage for hourly and part-time workers and their families. The Company recognized intangible assets of $13 million associated with this acquisition.

During September 2015, as part of its profitability enhancement initiatives, the Company decided to wind-down all of its retail insurance operations in Australia. As a result of this decision, the Company recognized an impairment of an associated finite-lived intangible asset. The impaired intangible asset related to the purchase of an Australian distribution network in 2009 that had an initial expected useful life of thirty years. The impairment expense of $13 million was included as part of the reorganization and related expenses in the Consolidated Statement of Operations.

U.S. Government, U.S. Agency and U.S. Agency RMBS:
Unrealized losses on securities issued or backed, (eithereither explicitly or implicitly)implicitly by the U.S. government are not analyzed for OTTI. The Company havehas concluded that the possibility of anya credit lossesloss on these securities is highly unlikely due to the explicit U.S. government guarantee onrelated to certain securities (e.g. GNMAGovernment National Mortgage Association issuances) and on others, the implicit guarantee related to other securities that has been validated by past actions (e.g. U.S. government bailout of FNMAFederal National Mortgage Association and FHLMCFederal Home Loan Mortgage Corporation during the 2008 credit crisis). Although these securities are not analyzed for credit losses, the securitiesthey are still evaluated for intention to sell and likely requirement to sell.

TheAt December 31, 2019, the gross unrealized losses of $10$2 million at December 31, 2017(2018: $16 million) were mainly due to foreign exchange losses. Based on analysis performed,At December 31, 2019, the Company does not anticipate any credit losses on its non-U.S. government fixed maturities held at December 31, 2017.maturities. In 2017,2019, the OTTI chargescharge on non-U.S. government fixed maturities mainly related to unrealized foreign exchange losses on certain securities where the forecasted recovery of the amortized cost of these securities was uncertain.
Corporate Debt:
To estimate credit losses for corporate debt securities, the Company's projected cash flows are primarily driven by assumptions regarding the probability of default and the severity associated with those defaults. The Company's default and loss severity rates are based on credit rating, credit analysis, industry analyst reports and forecasts, Moody’s historical default data and any other data relevant to the recoverability of the security. In 2017,2019, the OTTI chargescharge on corporate debt securities were mainly related to significant loss severity, unrealized foreign exchange losses on certain securities where the forecasted recovery of the amortized cost of these securities was uncertain, as well asand instances where the Company's intentCompany intended to sell.sell securities before the forecasted recovery of the amortized cost of these securities.

At December 31, 2019, CMBS had a weighted average estimated subordination percentage of 29% at December 31, 2017(20162018: 36%31%). Based on discounted cash flows at December 31, 20172019, the current level of subordination is sufficient to cover the estimated loan losses on the underlying collateral of the CMBS.
Non-agency RMBS:
ForTo estimate credit losses for non-agency RMBS, the Company's projected cash flows incorporated underlying data from widely accepted third-party data sources along with certain internal assumptions and judgments regarding the future performance of the security. These assumptions included the following: default, delinquency, loss severity and prepayment rates. The assumptions used to calculate the credit losses in 20172019 have not changed significantly since December 31, 20162018.
At December 31, 2017,2019, the fair value of the Company's non-agency RMBS was $47$85 million (2016: $57(2018: $41 million), consisting primarily of $34$54 million (2016: $40(2018: $31 million) of Prime and $8$11 million (2016: $10(2018: $5 million) of Alt-A MBS.

The Company also reviews subordination levels of itsthese securities to determine their ability to absorb credit losses of underlying collateral.

Equity Securities
There were no OTTI losses on equity securities in 2017. The OTTI losses on equity securities in 2016 are primarily due to the severity of their unrealized loss positions, for which the Company concluded the forecast recovery period was uncertain. The recognition of such losses does not necessarily indicate that sales will occur or that sales are imminent or planned. At December 31, 2017,2019, the fair value of the Company's equities was $636 million (2016: $639 million), which included $2 million (2016: $12 million) of gross unrealized losses.Company does not anticipate any credit losses on its CLO Debt.

7.FAIR VALUE MEASUREMENTS

Fair Value Hierarchy


Fair value is defined as the price to sell an asset or transfer a liability (i.e. the "exit price") in an orderly transaction between market participants. U.S. GAAP prescribes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data. The level in the hierarchy within which a given fair value measurement falls is determined based on the lowest level input that is significant to the measurement. The hierarchy is broken down into three levels as follows:


Level 1 - Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.


Level 2 - Valuations based on quoted prices in active markets for similar assets or liabilities, quoted prices for identical assets or liabilities in inactive markets, or for which significant inputs are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severities, etc.) or can be corroborated by observable market data.

7.FAIR VALUE MEASUREMENTS (CONTINUED)


Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The unobservable inputs reflect the Company's own judgments about assumptions that market participants might use.


The availability of observable inputs can vary from financial instrument to financial instrument and is affected by a wide variety of factors including, for example, the type of financial instrument, whether the financial instrument is new and not yet established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires significantly more judgment.


Accordingly, the degree of judgment exercised by management in determining fair value is greatest for financial instruments categorized inas Level 3. In periods of market dislocation, the observability of prices and inputs may be reduced for many financial instruments. This may lead the Company to change the selection of valuation technique (from market to cash flow approach) or may cause the Company to use multiple valuation techniques to estimate the fair value of a financial instrument. This circumstance could cause an instrument to be reclassified between levels within the fair value hierarchy.


Valuation Techniques


The valuation techniques, including significant inputs and assumptions generally used to determine the fair values of the Company's financial instruments as well as the classification of the fair values of its financial instruments in the fair value hierarchy are described in detail below.


Fixed Maturities


At each valuation date, the Company uses the market approach valuation technique to estimate the fair value of theits fixed maturities portfolio, whenwhere possible. ThisThe market approach includes, but is not limited to, prices obtained from third partythird-party pricing services for identical or comparable securities and the use of "pricing matrix models" using observable market inputs such as yield curves, credit risks and spreads, measures of volatility, and prepayment speeds. Pricing from third partythird-party pricing services is sourced from multiple vendors, whenwhere available, and the Company maintains a vendor hierarchy by asset type based on historical pricing experience and vendor expertise. WhenWhere prices are unavailable from pricing services, the Company obtains non-binding quotes from broker-dealers who are active in the corresponding markets. The valuation techniques including significant inputs and assumptions generally used to determine the fair values of the Company's fixed maturities by asset class as well as the classifications of the fair values of these securities in the fair value hierarchy are described in detail below.

U.S. governmentGovernment and agencyAgency


U.S. government and agency securities consist primarily of bonds issued by the U.S. Treasury and mortgage pass-through agencies such as the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation and the Government National Mortgage Association. As the fair values of U.S. Treasury securities are based on unadjusted quoted market prices in active markets, the fair values of these securities are classified as Level 1. The fair values of U.S. government agency securities are determined using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads are observable market inputs, the fair values of U.S. government agency securities are classified as Level 2.


Non-U.S. governmentGovernment


Non-U.S. government securities include bonds issued by non-U.S. governments and their agencies along with supranational organizations (collectively also known as sovereign debt securities). The fair values of these securities are based on prices obtained from international indices or valuation models that include inputs such as interest rate yield curves, cross-currency basis index spreads and country credit spreads for structures similar to the sovereign bond in terms of issuer, maturity and seniority. As the significant inputs used to price these securities are observable market inputs, the fair values of non-U.S. government securities are classified as Level 2.

Corporate debtDebt


Corporate debt securities consist primarily of investment-grade debt of a wide variety of corporate issuers and industries. The fair values of these securities are generally determined using the spread above the risk-free yield curve. These spreads are generally obtained from the new issue market, secondary trading and broker-dealer quotes. As the yields for the risk-free yield curve and the spreads are observable market inputs, the fair values of corporate debt securities are generally classified as Level 2. Where pricing is unavailable from pricing services, the Company obtains non-binding quotes from broker-dealers to estimate fair value. This is generally the case when there is a low volume of trading activity and current transactions are not orderly. In this event, the fair values of these securities are classified as Level 3.


Agency RMBS


Agency RMBS consist of bonds issued by the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation and the Government National Mortgage Association. The fair values of these securities are priced using a mortgage pool specific model which uses daily inputs from the active to be announced market and the spread associated with each mortgage pool based on vintage. As the significant inputs used to price these securities are observable market inputs, the fair values of Agency RMBS are classified as Level 2.


CMBS


CMBS mainly include mostly investment-grade bonds originated by non-agencies. The fair values of these securities are determined using a pricing model which uses dealer quotes and other available trade information along with security level characteristics to determine deal specific spreads. As the significant inputs used to price these securities are observable market inputs, the fair values of CMBS securities are generally classified as Level 2. Where pricing is unavailable from pricing services, the Company obtains non-binding quotes from broker-dealers to estimate fair value. This is generally the case when there is a low volume of trading activity and current transactions are not orderly. In this event, the fair values of these securities are classified as Level 3.

The fair values of these securities are determined using an option adjusted spread model or other relevant models, which use inputs including available trade information or broker quotes, prepayment and default projections based on historical statistics of the underlying collateral and current market data. As the significant inputs used to price these securities are observable market inputs, the fair values of Non-Agencynon-agency RMBS are generally classified as Level 2. Where pricing is unavailable from pricing services, the Company obtains non-binding quotes from broker-dealers to estimate fair value. This is generally the case when there is a low volume of trading activity and current transactions are not orderly. In this event, the fair values of these securities are classified as Level 2.3.


ABS


ABS mainly include mostly investment-grade bonds backed by pools of loans with a variety of underlying collateral, including automobile loan receivables,auto loans, student loans, credit card receivables and CLO debtcollateralized loan obligations ("CLOs") originated by a variety of financial institutions. The fair values of these securities are determined using a model which uses prepayment speeds and spreads sourced primarily from the new issue market. As the significant inputs used to price these securities are observable market inputs, the fair values of ABS are generally classified as Level 2. Where pricing is unavailable from pricing services, the Company obtains non-binding quotes from broker-dealers to estimate fair value. This is generally the case when there is a low volume of trading activity and current transactions are not orderly. In this event, the fair values of these securities are classified as Level 3.


Municipals


Municipals comprise revenue and general obligation bonds issued by U.S. domiciled state and municipal entities. The fair values of these securities are determined using spreads obtained from the new issue market, trade prices and broker-dealers quotes. As the significant inputs used to price these securities are observable market inputs, the fair values of municipals are classified as Level 2.


Equity Securities


Equity securities include common stocks, exchange-traded funds and bond mutual funds. As the fair values of common stocks and exchange-traded funds are based on unadjusted quoted market prices in active markets, the fair values of these securities are classified as Level 1. As bond mutual funds have daily liquidity, with redemptions based on the Net Asset Values per share ("NAV") of the funds, the fair values of these securities are classified as Level 2.



Other Investments



The fair value of an indirect investment in CLO-Equities is estimated using an income approach valuation technique, specifically an externally developed discounted cash flow model due to the lack of observable and relevant trades in secondary markets. As the significant inputs used to price this security are unobservable, the fair value of the indirect investment in CLO-Equities is classified as Level 3.

Other Investments


Other privately held securitiesinvestments include convertible preferred shares, common shares, convertible notes and notes payable. These securities are initially valued at cost, which approximates fair value. In subsequent measurement periods, the fair values of these securitiesinvestments are generally determined using capital statements obtained from each investee company. In order to assess the reasonableness of the information received from each investee company, the Company maintains an understanding of current market conditions, historical results, and emerging trends that may impact the results of operations, financial condition or liquidity of investee companies. In addition, the Company engages in regular communication with management at the investee companies. In 2018, the fair values of some of these investments were determined using an internally developed discounted cash flow model. As the significant inputs used to price these securities are unobservable, the fair valuevalues of these securitiesother privately held investments are classified as Level 3.

Indirect investments in CLO-Equities are classified as Level 3 as the fair values of these securities are estimated using an income approach valuation technique (discounted cash flow model) due to the lack of observable and relevant trades in secondary markets. Direct investments in CLO-Equities are also classified as Level 3 as the fair values of these securities are estimated using a liquidation valuation.


Overseas deposits include investments in private funds held by Syndicate 2007 in whichwhere the underlying investments are primarily U.S. government, Non-U.S.non-U.S. government and corporate fixed maturities.debt securities. The funds do not trade on an exchange, therefore are not included withinin available for sale investments. As the significant inputs used to price the underlying investments are observable market inputs, the fair values of overseas deposits are classified as Level 2.


Short-TermShort-term Investments


Short-term investments primarily comprise highly liquid securities with maturities greater than three months but less than one year from the date of purchase. These securities are classified as Level 2 because these securities are typically not actively traded due to their approaching maturity, and, as such,therefore their amortized cost approximates fair value. The fair values of short-term investments are classified as Level 2.


Derivative Instruments


Derivative instruments include foreign currencyexchange forward contracts and exchange traded interest rate swaps and commodity contracts that are customized to the Company's economic hedging strategies and trade in the over-the-counter derivative market. The fair values of these derivatives are determined using thea market approach valuation technique based on significant observable market inputs from third partythird-party pricing vendors, non-binding broker-dealer quotes and/or recent trading activity. Accordingly,As the significant inputs used to price these securities are observable market inputs, the fair values of these derivatives are classified as Level 2.

Weather derivatives relate to non-exchange traded derivative-based risk management products addressing weather risks. The fair values of these derivatives are determined using observable market inputs and unobservable inputs in combination with industry or internally developed valuation and forecasting techniques. Accordingly, the fair values of these derivatives are classified as Level 3.


Other underwriting-related derivatives include insurance and reinsurance contracts that are required to be accounted for as derivatives. These derivative contracts are initially valued at cost which approximates fair value. In subsequent measurement periods, the fair values of these derivatives are determined using internally developed discounted cash flow models. As the significant inputs used to price these derivatives are unobservable, the fair valuevalues of these contracts are classified as Level 3.

Other Investments - CLO-Equities

The CLO-Equities market continues to be relatively inactive with only a small number of transactions being observed, particularly as it relatesrelated to transactions involving CLO-Equities held by the Company. Accordingly, the fair values of investments in CLO-Equities are determined using models. Given that allvalue of the Company's direct investmentsindirect investment in CLO-Equities are past their reinvestment period, there is uncertainty regarding the remaining time until maturity. As such the Company's direct investments in CLO-Equities are estimated using a liquidation valuation. Indirect investments in CLO-Equities are valueddetermined using a discounted cash flow model prepared by an external investment manager.


The liquidation valuation is based on the fair values of the net underlying collateral which is determined by applying market discount margins by credit quality bucket. An increase (decrease) in the market discount margin would result in a decrease (increase) in value of the Company's CLO-Equities.

Regarding the discounted cash flow model, the default and loss severity rates are the most judgmental unobservable market inputs to the discounted cash flow model to which the valuation of the Company's indirect investment in CLO-Equities is most sensitive. A significant increase (decrease) in either of these significant inputs in isolation would result in a lower (higher) fair value estimatesestimate for investmentsthe investment in CLO-Equities and, in general, a change in default rate assumptions would be accompanied by a directionally similar change in loss severity rate assumptions. Collateral spreads and estimated maturity dates are less judgmental inputs as they are based on the historical average of actual spreads and the weighted average life of the current underlying portfolios, respectively. A significant increase (decrease) in either of these significant inputs in isolation would result in a higher (lower) fair value estimatesestimate for investmentsthe investment in CLO-Equities. In general, these inputs have no significant interrelationship with each other or with default and loss severity rates.


On a quarterly basis, the Company's valuation process for its indirect investment in CLO-Equities includes a review of the underlying collateral along with related discount margins by credit quality bucket used in the liquidation valuation and a review of the underlying cash flows and key assumptions used in the discounted cash flow model. The above significant unobservable inputs are reviewed and updated based on information obtained from secondary markets, including information received from the managers of the Company's CLO-Equity portfolio.CLO-Equities investment. In order to assess the reasonableness of the inputs the Company uses in its models,the discounted cash flow model, the Company maintains an understanding of current market conditions, historical results, as well asand emerging trends that may impact future cash flows. In addition, the assumptions the Company uses in its models are updated through regular communication with industry participants and ongoing monitoring of the deals in which the Company participates (e.g. default and loss severity rate trends).participates.

7.FAIR VALUE MEASUREMENTS (CONTINUED)

Other privately held securities are initially valued at cost which approximates fair value. In subsequent measurement periods, the fair values of these securities are determined using internally developed discounted cash flow models. These models include inputs that are specific to each investment. The inputs used in the fair value measurements include dividend or interest rates and appropriate discount rates. The selection of an appropriate discount rate is judgmental and is the most significant unobservable input used in the valuation of these securities. A significant increase (decrease) in this input in isolation could result in significantly lower (higher) fair value measurement for other privately held securities. Where relevant, the Company also considers the contractual agreements which stipulate methodologies for calculating the dividend rate to be paid upon liquidation, conversion or redemption. In order to assess the reasonableness of the inputs that are used in the discounted cash flow models, the Company maintains an understanding of current market conditions, historical results, as well as investee specific information that may impact future cash flows.

7.FAIR VALUE MEASUREMENTS (CONTINUED)

The transfers to Level 3 from Level 2 made during 2016 were primarily due to the lack of observable market inputs and multiple quotes from pricing vendors and broker-dealers for certain fixed maturities and as a result of a change in the valuation methodology used to fair value the CLO-equity fund. An income approach valuation technique (discounted cash flow model) was used to estimate the fair value of the CLO-equity fund at December 31, 2016. As the NAV practical expedient was not used to determine the fair value of the CLO-equity fund, the fair value of the fund was categorized within the fair value hierarchy.

Transfers out of Level 3 into Level 2

The transfers out of Level 3 into Level 2 from Level 3 made during 20172019 and 20162018 were primarily due to the availability of observable market inputs and multiple quotes from pricing vendors onfor certain fixed maturities.

Measuring the Fair Value of Other Investments Using Net Asset Valuations

The fair values of hedge funds, direct lending funds, private equity funds and real estate funds are estimated using NAVsnet asset valuations ("NAVs") as advised by external fund managers or third partythird-party administrators. For these funds, NAVs are based on the manager's or administrator's valuation of the underlying holdings in accordance with the fund's governing documents and in accordance with U.S. GAAP.

If there is a reporting lag between the current period end and reporting date of the latest available fund valuation for any hedge fund, the Company estimates fair values by starting with the most recently availablerecent fund valuation and adjusting for return estimates as well as any subscriptions, redemptions and distributions that took place during the current period. Return estimates are obtained from the relevant fund managers. Accordingly,managers therefore the Company does not typically have a reporting lag in fair value measurements of these funds. Historically, the Company's valuation estimates incorporating these return estimates have not significantly diverged from the subsequently received NAVs.

For direct lending funds, private equity funds, real estate funds and two2 of the Company's hedge funds, valuation statements are typically released on a three month reporting lag therefore, the Company estimates the fair value of these funds by starting with the prior quarter-endmost recent fund valuations and adjusting for capital calls, redemptions, drawdowns and distributions. Return estimates are not available from the relevant fund managers for these funds. Accordingly,funds therefore the Company typically has a reporting lag in its fair value measurements of these funds. In 2017,2019, funds reported on a lag represented 44% (2016: 35%68% (2018: 61%) of the Company's total other investments balance.

The Company often does not have access to financial information relating to the underlying securities held within the funds therefore management is unable to corroborate the fair values placed on the securities underlying the asset valuations provided by fund managers or fund administrators. In order to assess the reasonableness of the NAVs, the Company performs a number of monitoring procedures on a quarterly basis, to assess the quality of the information provided by fund managers and fund administrators. These procedures include, but are not limited to, regular review and discussion of each fund's performance with its manager, regular evaluation of fund performance against applicable benchmarks and the backtesting of the Company's fair value estimates against subsequently received NAVs. Backtesting involves comparing the Company's previously reported fair values for each fund against NAVs per audited financial statements (for year-end values) and final NAVs from fund managers and fund administrators (for interim values).

The fair values of hedge funds, direct lending funds, private equity funds and real estate funds are measured using the NAV practical expedient, therefore the fair values of these funds have not been categorized within the fair value hierarchy.

Financial Instruments Disclosed, But Not Carried, at Fair Value

The fair value of financial instruments accounting guidance also applies to financial instruments disclosed, but not carried, at fair value, except for certain financial instruments, including insurance contracts.

TheAt December 31, 2019, the carrying values of cash and cash equivalents (includingincluding restricted amounts),amounts, accrued investment income, receivable for investments sold, certain other assets, payable for investments purchased and certain other liabilities approximated their fair values at December 31, 2017, due to their respective short maturities. As these financial instruments are not actively traded, their fair values are classified as Level 2.

TheAt December 31, 2019, the carrying value of mortgage loans held-for-investment approximated their fair value at December 31, 2017.value. The fair values of mortgage loans are primarily determined by estimating expected future cash flows and discounting them using current interest rates for similar mortgage loans with similar credit risk or are determined from pricing for similar loans. As mortgage loans are not actively traded, their fair values are classified as Level 3.

Offsetting Assets and Liabilities


The Company's derivative instruments are generally traded under International Swaps and Derivatives Association master netting agreements which establish terms that apply to all transactions. In the event of a bankruptcy or other stipulated event, master netting agreements provide that individual positions be replaced with a new amount, usually referred to as the termination amount, determined by taking into account market prices and converting into a single currency. Effectively, this contractual close-out netting reduces credit exposure from gross to net exposure. A

Reserving Methodology

Sources of Information
The Company's loss reserving process begins with the collection and analysis of paid and incurred claim data for each of the Company's segments. The segmental data is disaggregated by reservingreserve class and further disaggregated by underwriting year (i.e. theand accident year. Underwriting year in which the contract generating the premium and losses incepted). Underwritingor accident year information is used to analyze the Company's business and subsequently allocateto estimate reserves to the respective accident years.for losses and loss expenses. Reserve classes are selected to ensure that the underlying contracts have homogeneous loss development characteristics, while remaining large enough to make the estimation of trends credible. ThisThe Company's reserve classes are reviewed on a regular basis and adjusted over time as the Company's business evolves. The paid and incurred claim data, in addition to industry benchmarks, serves as a key input to many of the methods employed by the Company's actuaries. The relative weights assigned to its ownthe Company's historical loss data versus industry data vary according tobased on a number of factors including the length ofCompany's historical track record and the development profile for the reservingreserve class being evaluated.evaluated (Seerefer to 'Claim Tail Analysis' and 'Net Incurred and Paid Claims Development Tables By Accident Year' below for further details by reserve class.)details).

Actuarial Analysis
Multiple actuarial methods are available to estimate ultimate losses. Each method has its own assumptions and its own advantages and disadvantages, with no single estimation method being better than the others in all situations and no one set of assumption variables being meaningful for all reserve classes. The relative strengths and weaknesses of the particular estimation methods when applied to a particular group of claims can also change over time.

9.RESERVE FOR LOSSES AND LOSS EXPENSES (CONTINUED)


The following is a brief description of the reserve estimation methods commonly employed by the Company's actuaries:actuaries including a discussion of their particular strengths and weaknesses:
Expected Loss Ratio Method ("ELR Method"): This method estimates ultimate losses for an accident year or underwriting year by applying an expected loss ratio to the earned or written premium for that year. Generally, expected loss ratios are based on one or more of (a) an analysis of historical loss experience to date, (b) pricing information and (c) industry data, adjusted as appropriate, to reflect changes in rates, loss and exposure trends, and terms and conditions. This method is insensitive to actual incurred losses for the accident year or underwriting year in question and is, therefore, often useful in the early stages of development when very few losses have been incurred. Conversely, the lack of sensitivity to incurred/paid losses for the accident year or underwriting year in question means that this method is usually inappropriate in later stages of an accident year or underwriting year’s development.

Loss Development Method (also referred to as the Chain Ladder Method or Link Ratio Method): This method assumes that the losses incurred/paid for each accident year or underwriting year at a particular development stage follow a relatively similar pattern. It assumes that on average, every accident year or underwriting year will display the same percentage of ultimate losses incurred/paid at the same point in time after the inception of that year. The percentages incurred/paid are established for each development stage (e.g. 12 months, 24 months, etc.) after examining historical averages from historical loss development data and/or external industry benchmark information. Ultimate losses are then estimated by multiplying the actual incurred/paid losses by the reciprocal of the established incurred/paid percentage. The strengths of this method are that it reacts to loss emergence/payments and that it makes full use of historical claim emergence/payment experience. However, this method has weaknesses when the underlying assumption of stable loss development/payment patterns is not valid. This could be the consequence of changes in business mix, claim inflation trends or claim reporting practices and/or the presence of large claims, amongst other things. Furthermore, this method is usually inappropriate in later stages of an accident year or underwriting year’s development.

tends to produce volatile estimates of ultimate losses where there is volatility in the underlying incurred/paid patterns. In particular, where the expected percentage of incurred/paid losses is low, small deviations between actual and expected claims can lead to very volatile estimates of ultimate losses. As a result, this method is often unsuitable at early development stages for an accident year or underwriting year.

Bornhuetter-Ferguson Method ("BF Method"): This method can be seen as a combination of the ELR and Loss Development Methods, under which the Loss Development Method is given progressively more weight as an accident year or underwriting year matures. The main advantage of the BF Method is that it provides a more stable estimate of ultimate losses than the Loss Development Method at earlier stages of development, while remaining more sensitive to emerging loss development than the ELR Method. In addition, the BF Method allows for the incorporation of external market information through the use of expected loss ratios, whereas the Loss Development Method does not incorporate such information.

In addition, the BF Method allows for the incorporation of external market information through the use of expected loss ratios, whereas the Loss Development Method does not incorporate such information.
As part of the loss reserve reviewreserving process, the Company's actuaries employ the estimation method(s) that they believe will produce the most reliable estimate of ultimate losses, at that particular evaluation date, for each reserve class and accident year or underwriting year combination. Often, this is a blend (i.e. weighted average) of the results of two or more appropriate actuarial methods. These ultimate loss estimates are generally utilized to evaluate the adequacy of ultimate loss estimates for previous accident or underwriting years, as established in the prior reporting period. For the initial estimate of the current accident or underwriting year, the available claim data is typically insufficient to produce a reliable estimate of ultimate losses. As a result, initial estimates for an accident or underwriting year are generally based on the ELR Method for longer tailed lines and a BF Method for shorter tailed lines. The initial ELR for each reserve class is established collaboratively by the Company's actuaries, underwriters and management at the start of the year as part of the planning process, taking into consideration prior accident years’ or underwriting years' experience and industry benchmarks, adjusted after considering factors such as loss and exposure trends, rate differences, changes in contract terms and conditions, business mix changes and other known differences between the current year and prior accident or underwriting years. The initial expected loss ratios for a given accident or underwriting year may be modified over time if the underlying assumptions, such as loss development or premium rate changes, differ from the original assumptions.

Key Actuarial Assumptions
The use of the above actuarial methods requires the Company to make certain explicit assumptions, the most significant of which are: (1) expected loss ratios and (2) loss development patterns.
In earlier years, significant reliance was placed on industry benchmarks in establishing expected loss ratios and selecting loss development patterns. Over time, more reliance has been placed on historical loss experience in establishing these ratios and selecting these patterns where the Company believes the weight of its own actual experience has become sufficiently credible for consideration. The weight given to the Company's experience differs for each of the three claim tail classes (refer to 'Claim Tail Analysis' below for further details). In establishing expected loss ratios for the insurance segment, consideration is given to a number of other factors, including exposure trends, rate adequacy on new and renewal business, ceded reinsurance costs, changes in claims emergence and underwriters’ view of terms and conditions in the market environment. For the reinsurance segment, expected loss ratios are based on a contract-by-contract review, which considers information provided by clients together with estimates provided by underwriters and actuaries about the impact of changes in pricing, terms and conditions and coverage. Market experience of some classes of business as compiled and analyzed by an independent actuarial firm has also been considered, as appropriate. The weight given to experience differs for each of the three claim tails.

Claim Tail Analysis
Short-tail Business
Short-tail business generally includes exposures for which losses are usually known and paid within a relatively short period of time after the underlying loss event has occurred. The majority of development for an accident year or underwriting year is expected to be recognized in the subsequent one to three years. The key actuarial assumptions for short-tail business in early accident years were primarily developed with reference to industry benchmarks for both expected loss ratios and loss development patterns. As the Company's own historical loss experience amassed, it gained credibility and became relevant for consideration in establishing these key actuarial assumptions. As a result, the Company gradually increased the weighting assigned to its own historical loss experience in selecting the expected loss ratios and loss development patterns utilized to establish estimates of ultimate losses for an accident year. Due to the relatively short reporting and settlement patterns for short-tail business, more weight is generally placed uponon experience-based methods and other qualitative considerations in establishing reserves for both recent and more mature accident years. The majority of development for an accident year or underwriting year is expected to be recognized in the subsequent one to three years.

Medium-tail Business
Medium-tail business generally has claim reporting and settlement periods that are longer than those of short-tail reserve classes. For the Company's earliest accident and underwriting years, initial key actuarial expected loss ratio and loss development assumptions were established utilizing industry benchmarks. Due to the longer claim tail, the length of time required to develop its own credible loss history for use in the reserve process is greater for medium-tail business than for short-tail business. As a result, the number of years where the Company has relied heavily on industry benchmarks to establish its key actuarial assumptions is greater for medium-tail business.

Long-tail Business
The claim tails for long-tail business, inIn contrast to short and medium-tail business, the claim tail for long-tail business is expected to be notably longer, as claims are often reported and ultimately paid or settled years, or even decades, after the related loss events occur. As a general rule, estimates of accident year or underwriting year ultimate losses for long-tail business are notably more uncertain than those for short and medium-tail business. To date, key actuarial assumptions for long-tail business have been derived extensively from a combination of industry benchmarks supplemented with the Company own historical experience. Given the Company's relatively short operating history in comparison to the development tail for this business, the Company does not believe that its own historical loss development for long-tail business has amassed an appropriate volume to serve as a fully credible input into the key actuarial assumptions previously outlined.experience. While industry benchmarks that the Company believes reflect the nature and coverage of its business are considered, actual loss experience may differ from the benchmarks based on industry averages. Due to the length of the development tail for this business, reserve estimates for most accident years and underwriting years are predominantly based on the BF Method or ELR methodMethod and the consideration of qualitative factors.

Reserving for Significant Catastrophic Events
The Company cannot estimate losses from widespread catastrophic events, such as hurricanes and earthquakes, using the traditional actuarial methods described above. Rather, lossLoss reserves for such events are estimated by management in collaboration with actuaries, claim handlers and underwriters after a catastrophe occurs by completing an in-depth analysis of individual contracts which may potentially behave been impacted by the catastrophic event. This in-depth analysis may rely on several sources of information including:

estimates of the size of insured industry losses from the catastrophic event and the Company's corresponding market share;
a review of the Company's portfolio of contracts performed to identify those contracts which may be exposed to the catastrophic event;
a review of modeled loss estimates based on information previously reported by customers and brokers, including exposure data obtained during the underwriting process;
discussions of the impact of the event with customers and brokersbrokers; and
catastrophe bulletins published by various independent statistical reporting agencies.

8.RESERVE FOR LOSSES AND LOSS EXPENSES (CONTINUED)


A blend of these information sources is generally used to arrive at aggregate estimates of the ultimate losses arising from the catastrophic event. In subsequent reporting periods, changes in paid and incurred losses in relation to each significant catastrophe are reviewed and adjustments are made to estimates of ultimate losses for each event if there are developments that are different from previous expectations. Adjustments are recorded in the period in which they are identified.

Selection of Reported Reserves – Management’s Best Estimate
The Company's loss reserving process involves the collaboration of its underwriting, claims, actuarial, legal, ceded reinsurance and finance departments, includes various segmental committee meetings and culminates with the approval of a single point best estimate by the Company's Group Reserving Committee, which comprises senior management. In selecting this best estimate, management considers actuarial estimates and applies informed judgment regarding qualitative factors that may not be fully captured in these actuarial estimates. Such factors include, but are not limited to:to, the timing of the emergence of claims, volume and complexity of claims, social and judicial trends, potential severity of individual claims and the extent of internalCompany historical loss data versus industry information. While these qualitative factors are considered in arriving at the point estimate, no specific provisions for qualitative factors are established.

Prior Year Development

Prior year reserve development arises from changes to loss and loss expense estimates related to loss events that occurred in previous calendar years. Such development is summarized by segment in the following table:

Short-tail business

Short-tail business includes the underlying exposures in property and other, marine and aviation reserve classes within the insurance segment and the property and other reserve class within the reinsurance segment.

Development from these classes contributed $60 million, $148 million and $152 million total net favorable prior year reserve development in 2017, 2016 and 2015, respectively, and primarily reflected the recognition of better than expected loss emergence in the years.

Medium-tail business

Medium-tail business consists primarily of insurance and reinsurance professional reserve classes, credit and political risk insurance reserve class, and credit and surety reinsurance reserve class.

The reinsurance professional reserve class recognized $44 million, $30 million and $38 million of net favorable prior year development in 2017, 2016 and 2015, respectively. The net favorable prior year loss developments on this reserve class continued to reflect the generally favorable experience on earlier accident years as the Company continued to transition to more experience based methods. As loss experience on these accident years has generally been better than expected, this resulted in the recognition of net favorable prior year reserve development.

The insurance professional reserve class recorded net favorable prior year development of $26 million in 2017 reflecting the generally favorable experience on earlier accident years as the Company transitions to more experienced based methods. As loss experience has generally been better than expected, this resulted in the recognition of net favorable prior year reserve development. The insurance professional reserve class recorded net favorable prior year reserve development of $14 million in 2016, also driven by overall better than expected development. The insurance professional reserve class recorded adverse prior year development of $14 million in 2015 due to reserve strengthening on the Australian book of business during the three months ended September 30, 2015.

The reinsurance credit and surety reserve class recorded net favorable prior year reserve development of $33 million, $10 million, and $27 million in 2017, 2016, and 2015, respectively due to the recognition of generally better than expected loss emergence.

The credit and political risk reserve class recorded net adverse development of $15 million in 2015 primarily related to an increase in loss estimates for one specific claim.

Long-tail business

Long-tail business consists primarily of liability and motor reserve classes.

The motor reserve class contributed net favorable prior year reserve development of $1 million, $55 million and $37 million, in 2017, 2016 and 2015, respectively. The net favorable prior year reserve development on the motor reserve class in 2016 and 2015 related to favorable loss emergence trends on several classes of business spanning multiple accident years. Net favorable prior year development in 2017 was impacted by the U.K. Ministry of Justice's announcement of a decrease in the discount rate used to calculate lump sum awards in U.K. bodily injury cases, known as the Ogden Rate. Effective March 20, 2017, the Ogden rate changed from plus 2.5% to minus 0.75%.

The reinsurance liability reserve classes contributed net favorable prior year development of $43 million, $44 million and $46 million in 2017, 2016 and 2015, respectively. The net favorable prior year development primarily reflected the progressively increased weight given by management to the generally favorable emerging loss experience on earlier accident years.

This favorable prior year development was partially offset by net adverse prior year development in the insurance liability reserve class of $8 million, $8 million and $27 million in 2017, 2016 and 2015, respectively, primarily related to reserve strengthening within the excess casualty book. In particular, the adverse development during 2015 was mainly driven by a higher frequency of large auto liability claims.

Significant Catastrophe Events
At December 31, 20172019, net reserve for losses and loss expenses includesincluded estimated amounts for numerous catastrophe events. The magnitude and/or complexity of losses arising from certain of these events, in particular Japanese Typhoons Hagibis, Faxai and Tapah, Hurricane Dorian and the Australia Wildfires which occurred in 2019 together with Hurricanes Michael and Florence, California Wildfires and Typhoon Jebi which occurred in 2018 as well as Hurricanes Harvey, Irma and Maria, the two earthquakes in Mexico and the wildfires in Northern and Southern California Wildfires which occurred in 2017 inherently increasesincrease the level of uncertainty and, therefore, the level of management judgment involved in arriving at estimated net reserves for losses and loss expenses. As a result, actual losses for these events may ultimately differ materially from current estimates.

Short-tail business
Short-tail business includes the underlying exposures in the property and other, marine, and aviation reserve classes in the insurance segment, and the underlying exposures in the property and other reserve class in the reinsurance segment.
These reserve classes recognized net adverse prior year reserve development of $85 million in 2019 including net adverse prior year reserve development of $133 million recognized by the reinsurance property and other reserve class, partially offset by net favorable prior year reserve development of $33 million contributed by the insurance marine reserve class and net favorable prior year reserve development of $11 million contributed by the insurance property and other reserve class.
The net adverse prior year reserve development of $133 million recognized by the reinsurance property and other reserve class was due to an increase in loss estimates attributable to Hurricanes Irma and Michael consistent with industry trends, an increase in loss estimates attributable Typhoon Jebi consistent with updated industry insured loss estimates, and reserve strengthening within the U.S. regional and commercial proportional property books of business and the European proportional property book of business.
These reserve classes contributed net favorable prior year reserve development of $86 million in 2018 reflecting overall better than expected loss emergence related to the 2017 catastrophe events.
These reserve classes contributed $60 million of net favorable prior year reserve development in 2017 reflecting overall better than expected loss emergence.
Medium-tail business
Medium-tail business consists primarily of insurance and reinsurance professional lines reserve classes, insurance credit and political risk reserve class and reinsurance credit and surety reserve class.
For the year ended December 31, 2019, the insurance professional lines reserve class recorded net favorable prior year reserve development of $12 million (2018: $32 million, 2017: $26 million), reflecting generally favorable experience on older accident years as the Company continued to transition to more experience based actuarial methods.
For the year ended December 31, 2018, the reinsurance professional lines reserve class recorded net favorable prior year reserve development of $21 million (2017: $44 million), reflecting generally favorable experience on older accident years as the Company continued to transition to more experienced based actuarial methods.
For the year ended December 31, 2019, the insurance credit and political risk reserve class recorded net favorable prior year reserve development of $19 million reflecting generally better than expected loss emergence.
For the year ended December 31, 2019, the reinsurance credit and surety reserve class recorded net favorable prior year reserve development of $53 million (2018: $33 million, 2017: $33 million), reflecting generally better than expected loss emergence.

Long-tail business
Long-tail business consists primarily of insurance and reinsurance liability reserve classes and reinsurance motor reserve class.
For the year ended December 31, 2019, the insurance liability reserve class recognized net adverse prior year reserve development of $25 million (2018: $22 million, 2017: $8 million). The net adverse prior year reserve development in 2019 was primarily related to reserve strengthening within the Company's U.S. excess casualty and U.S. primary casualty books of business. The net adverse prior year reserve development in 2018 was primarily related to reserve strengthening within the Company's U.S. excess casualty book of business. The net adverse prior year reserve development in 2017 was primarily attributable to reserve strengthening within the Company's run-off Bermuda excess casualty book of business.
For the year ended December 31, 2019, the reinsurance liability reserve classes recognized net favorable prior year reserve development of $31 million (2018: $23 million, 2017: $43 million). The net favorable prior year reserve development in 2019, 2018 and 2017 was due to progressively increased weight given by management to experience based indications on older accident years.
For the year ended December 31, 2019, the reinsurance motor reserve class recognized net favorable prior year reserve development of $71 million (2018: $23 million 2017: $1 million). The net favorable prior year reserve development in 2019 was impacted by the increase in the Ogden discount rate and changes in related actuarial assumptions. The Ogden Rate which is used to calculate lump sum awards in U.K. bodily injury cases, changed from minus 0.75% to minus 0.25%, effective August 5, 2019. The net favorable prior year reserve development in 2018 was primarily attributable to non proportional treaty business on older accident years. The net favorable prior year development in 2017 was impacted by the decrease in the Ogden Rate, which changed from plus 2.5% to minus 0.75%, effective March 20, 2017.
Net Incurred and Paid Claims Development Tables Byby Accident Year

The following tables present net incurred and paid claims development by accident year, total incurred-but-not-reported liabilities plus expected development on reported claims, cumulative reported claims frequency and claims duration for each reserve class. The loss development trianglestables are presented on an accident year basis for both the insurance and reinsurance segments. The Company does not discount unpaidreserves for losses and loss expense reserves.

Non-U.S. dollar denominated loss data is converted to U.S. dollar at the rates of exchange in effect at the balance sheet date for material underlying currencies. Fluctuations in foreign currency exchange rates may cause material shifts in loss development. Reserves for losses and loss expenses disclosed in the Consolidated Balance Sheets,consolidated balance sheets are also revaluedremeasured using the rates of exchange ratein effect at the balance sheet date.

The Company has presented separate loss development tables for the Aviabel and Novae business prospectively from the date of acquisition. The prospective treatment for the acquisition of Aviabel and Novae was adopted primarily due to the data necessary to produce the loss development tables by accident year not being available prior to the acquisition date. With regard to establishing the fair value of reserves for losses and loss expenses for Novae at the acquisition date, weight was given to the observable value of these reserves based on a Reinsurance to Close (“RITC”) transaction of the Syndicate’s 2015 and prior years of account, which was completed prior to the allocation of purchase price. Management made no change to the initial estimate when establishing its best estimate of reserves for losses and loss expenses at December 31, 2017. This is consistent with the Company's general approach of recognizing all or part of the anticipated cost of third party liability commutations if the transaction has either completed or is considered sufficiently likely to be completed in the near term.

To the extent that the Company enters into a disposition, the effects of the disposition are reported on a retrospective basis by removing the balances associated with the disposed of business.

There are many considerations in establishing loss reserves and an attempt to evaluate loss reserves using solely the data presented in these tables could be misleading. The Company cautions against mechanical application of standard actuarial methodologies to project ultimate losses using data presented in this disclosure.

The reporting of cumulative claims frequency for the reserve classes within the insurance segment has been measured by counting the number of unique claim references including claim references assigned to nil and nominal case reserves. Claim references are grouped by claimant by loss event for each class of business.reserve class. For certain insurance facilities and business produced by managing general agents where underlying data is reported to the Company in an aggregated format, the information necessary to provide cumulative claims frequency is not available therefore reporting of claims frequency is deemed to be impracticable.

Insurance Marine

This reserve class includes the marine line of business which provides cover for traditional marine classes, including offshore energy, cargo, liability, recreational marine, fine art, specie, as well asand hull and war. Offshore energy coverage includes physical damage, business interruption, operators extra expense and liability coverage for all aspects of offshore upstream energy, from exploration and construction through the operation and distribution phases. The complex nature of claims arising under marine policies tends to result in reporting and payment patterns that are longer than those of the property and other reserve class. Exposure to natural perils such as windstorm and earthquake can result in volatility.

Insurance Aviation

This reserve class includes the aviation line of business which provides cover for hull and liability, and specific war coverscover primarily for passenger airlines but also for cargo operations, general aviation operations, airports, aviation authorities, security firms and product manufacturers. The claims reporting pattern varies by insurance coverage provided. Losses arising from war or terrorism and damage to hulls of aircraft are generally reported quickly compared with liability claims which involve passengers and third parties whichand generally exhibit longer reporting and payment patterns. To date, the claims reported to the Company have predominantly related to damage to hulls, therefore, reporting and payment patterns have typically exhibited a relatively short tail.

Insurance Credit and Political Risk

This reserve class includes the credit and political risk line of business which provides credit and political risk insurance products for banks, commodity traders, corporations and multilateral and export credit agencies. Cover is provided for a range of risks including sovereign default, credit default, political violence, currency inconvertibility and non-transfer, expropriation, aircraft non-repossession and contract frustration due to political events.

The credit insurance coverage is primarily for lenders seeking to mitigate the risk of non-payment from their borrowers. In order to claim compensation under a credit insurance contract, the insured (most often a bank) cannot assign, without the Company's prior agreement, the insured contract (most often a loan) to any third party and is normally obliged to hold a material portion of insured asset on their own books, unhedged and uninsured. Claims for this business tend to be characterized by their severity risk, as opposed to their frequency risk. Claim reporting and payment patterns are anticipated to be volatile. Under the notification provisions of credit insurance policies issued by the Company, it anticipates being advised of an insured event within a relatively short time period. As a result,Consequently, the Company generally estimates ultimate losses based on a contract-by-contract analysis which considers the contracts’ terms, the facts and circumstances of underlying loss events and qualitative input from claims managers.

Insurance Liability

This reserve class includes the liability line of business which primarily targets primary and low/low to mid-level excess and umbrella commercial liability risks in the U.S. wholesale markets in addition to primary and excess of loss employers, public and products liability business predominately in the U.K. This reserve class also includesdiscontinued lines - Novae specifically the international liability line of business that Novae exited or placed into run-off in the fourth quarter of 2016. Target industry sectors include construction, manufacturing, transportation and trucking and other services. The delay between the writing of a contract, notification and subsequent settlement of a claim in respect of that contract results in claim reporting and payment patterns that are typically long taillong-tail in nature. A consequence of the claim development tail is that this line of business is particularly exposed, amongstamong a number of uncertainties, to the potential for unanticipated levels of claim inflation relative to that assumed when the contracts were written. Factors influencing claim inflation on this class can include, but are not limited to, underlying economic and medical inflation, judicial inflation, mass tort and changing social trends.

Reinsurance Segment

The presentation of net incurred and paid claims development tables by accident year for the reinsurance segment is challenging due to the need to the allocate loss information related to proportional treaties to the appropriate accident years. Information related to proportional treaty reinsurance contracts areis generally submitted to the Company using quarterly bordereau reporting by underwriting year, with a supplemental listing of large losses. The largeLarge losses can be allocated to the corresponding accident years accurately. However, theThe remaining losses can generally only be allocated to accident years based on estimated premiums earned and loss reporting patterns. To the extent management’s assumptions and allocation procedures differ from the actual loss development patterns, the actual loss development may differ materially from the net incurred and paid claims development presented in the tables below.

The reporting of cumulative claims frequency for the reserve classes within the reinsurance segment is deemed to be impracticable. Theimpracticable as the information necessary to provide cumulative claims frequency for these reserve classes is not available to the Company.

Reinsurance Professional Lines

This reserve class includes the professional line of business which provides coverprotection for directors' and officers' liability, employment practices liability, medical malpractice, professional indemnity, environmental liability and miscellaneous errors and omissions insurance risks. The underlying business is predominantly written on a claims-made basis. BusinessThis business is written on both a proportional and excess of loss basis. Typically, this reserve class is anticipated to exhibit medium to long-tail claim reporting and payment patterns.
With respect to key actuarial assumptions, the Company is progressively giving more weight torelies on its own experience when establishing expected loss ratios and selected loss development patterns, though it continues to consider industry benchmarks.patterns. Loss reporting patterns for professional lines business tend to be volatile, causing instability in actuarial indications based on incurred loss data until an accidentunderwriting year matures for a number of years.matures. Consequently, initial loss reserves for an accident year or underwriting year are generally based upon anon the ELR methodMethod and the consideration of relevant qualitative factors. As accident and underwriting years mature, the Company increasingly gives more weight to methods that reflect its actual experience until its selections are based almost exclusively on experience-based methods. The Company evaluates the appropriateness of the transition to experience-based methods at the reserve class level, commencing this transition when it believes that its incurred loss development is sufficient to produce meaningful actuarial indications. The rate at which the Company transitions fully to sole reliance on experience-based methods can vary by reserve class and by year, depending on its assessment of the stability and relevance of such indications.

Reinsurance Motor

This reserve class includes the motor line of business which provides coverprotection to insurers for motor liability and motor property damage losses arising from any one occurrence. A loss occurrence can involve one or many claimants where the ceding insurer aggregates the claims from the occurrence.

This reserve class also includes discontinued lines - Novae specifically the motor reinsurance line of business that Novae exited or placed into run-off in the first quarter of 2017. The Company offers traditional proportional and non-proportional reinsurance as well as structured solutions predominantly relating to European exposures.
The business written on a proportional basis has expanded significantly since 2010 and now represents the majority of the premium written withinin this line of business. Most of the premium relates to a relatively small number of large United Kingdom ("U.K.") and, to a lesser extent, Greek quota share treaties.reinsurance treaty contracts. The motor proportional class generally has a significantly shorter reported and payment pattern, relative to the motor non-proportional class.

The motor non-proportional business consists of standard excess of loss contracts written for cedants in several European countries with most of the premium related to two major markets, U.K. and France. Since 2009/2010, an increasing number of large bodily injury settlements in the U.K. market were settled using indexed annuities (Periodical Payment Orders "PPOs"). This led to a materially longer development tail on the older accident years for the U.K. non-proportional motor book. This also resulted in a move towards generally lower treaty attachment points and the inclusion of capitalization clauses on a number of U.K. motor treaties to help mitigate the lengthening of the development tail on more recent accident years. Despite the trend toward a greater number of claims settlements using PPOs, there has been a trend towards generally quicker and more adequate reporting of losses in recent years.

9.8.RESERVE FOR LOSSES AND LOSS EXPENSES (CONTINUED)




In 2017, the U.K. Ministry of Justice announced a decrease in the discount rate to be used to calculate lump sum awards in U.K. bodily injury cases, known as the Ogden Rate. Effective March 20, 2017, the Ogden rate changed from plus 2.5% to minus 0.75%. This resulted in a trend toward a lower number of claims settlements using PPOs and an increase in projected ultimate losses, particularly related to recent accident years.
Effective August 5, 2019, the Ogden rate changed from minus 0.75% to minus 0.25%. This resulted in a decrease in projected ultimate losses, particularly related to recent accident years.

9.RESERVE FOR LOSSES AND LOSS EXPENSES (CONTINUED)



Novae

In October 2017, the Company acquired Novae, a diversified property and casualty (re)insurance business operating through Syndicate 2007 at Lloyd’s. Novae writes a wide range of property, marine, aviation, credit and political risk, professional lines, motor and liability business on a worldwide basis. In addition, cover is also offered for various other lines of business, including agriculture reinsurance, bloodstock, construction, accident and health, political violence and engineering reinsurance.

The Company has determined that reporting of cumulative claims frequency for direct insurance lines of business is impracticable as data by accident year is not available. Further for certain insurance facilities and business produced by managing general agents where underlying data is reported to the Company in an aggregated format, the information necessary to provide cumulative claims frequency is not available therefore reporting of claims frequency is deemed to be impracticable. In addition, the information necessary to provide cumulative claims frequency for reinsurance lines of business is not available to the Company, therefore reporting of claims frequency is deemed to be impracticable.

Property: The property line of business includes exposures related to worldwide direct property facilities for retail and small commercial risks, worldwide catastrophe reinsurance written on a proportional and excess of loss basis, and worldwide direct and facultative cover of larger commercial risks. In general, reporting and payment patterns are relatively short-tailed although they can be volatile due to the incidence of catastrophe events.

Marine: The marine line of business covers marine liability, energy, hull, cargo, specie and war exposures and includes risks which are mostly written on a direct basis. In addition, a relatively small amount of marine business is written on an excess of loss basis. The complex nature of claims arising under marine policies tends to result in reporting and payment patterns that are longer than those of the property lines of business.

Aviation: The aviation line of business provides hull, liability, and war cover and predominantly relates to an excess of loss reinsurance account, with a smaller amount of satellite and general aviation business written on a proportional basis. Payments relating to hull damage can settle relatively quickly but an element of the claims profile will often be longer tail due to liability exposures.

Credit & political risk: International trade credit and political risks business was written from 2000 onwards. Typically this business is anticipated to exhibit medium to long tail claim reporting and payment patterns.

Professional Lines: Professional lines business provides cover for directors’ and officers’ liability, errors and omissions liability, crime, professional indemnity, cyber and medical malpractice and includes risks which are mainly written on a direct basis. Most professional lines business written from 2002 onwards relates to non-U.S. exposures. Typically, this business is anticipated to exhibit medium to long tail claim reporting and payment patterns.

Motor: Motor line of business was written on a direct basis until this business was discontinued in 2015. Motor business has been written on an excess of loss basis since 2010. The business predominantly covers U.K. based risks. Typically, this business is anticipated to exhibit long-tail claim reporting and payment patterns.

Liability: The general liability reinsurance line of business provides cover for directors’ and officers’ liability, errors and omissions liability, crime, professional indemnity, cyber and medical malpractice written on an excess of loss basis from 2010 onwards. Most general liability reinsurance business written relates to non-U.S. commercial liability insurance but also includes U.S. casualty excess of loss reinsurance from 2015. Claim reporting and payment patterns are typically long-tail in nature and, therefore, subject to increased uncertainty surrounding future loss development. In particular, claims can be subject to inflation from a number of sources including, but not limited to, economic and medical inflation, judicial inflation and changing social trends.

a)Concentrations of Credit Risk
Credit Risk Aggregation
The Company monitors and manages the aggregation of credit risk on a group-wide basis allowing it to consider exposure management strategies for individual companies, countries, regions, sectors and any other relevant inter-dependencies. The Company's credit exposures are aggregated based on the origin of risk. As part of its credit aggregation framework, the Company also assigns aggregate credit limits by single counterparty (a group of companies or country). These limits are based on and adjusted for a variety of factors including the prevailing economic environment and the nature of the underlying credit exposures. The Company's credit aggregation measurement and reporting process is facilitated by its credit risk exposure database, which contains relevant information on counterparty details and credit risk exposures. The Company also licenses third partythird-party tools to provide credit risk assessments.
Credit risk aggregation is also managed through minimizing overlaps in underwriting, financing and investing activities.
The assets that potentially subject the Company to concentrations of credit risk consist principally of cash and investments, reinsurance recoverable on unpaid and (re)paid claims and insurance and reinsurance premiums balances receivable, balances, as described below:
(i)     Cash and Investments
In order to mitigate concentration and operational risks related to cash and cash equivalents, the Company limits the maximum amount of cash that can be deposited with a single counterparty and limits acceptable counterparties based on current rating, outlook and other relevant factors.
The Company's investment portfolio is managed by external investment managers in accordance with its investment guidelines. The Company limits such credit risk through diversification, issuer exposure limitationlimits graded by ratings and, with respect to custodians, through contractual and other legal remedies. Excluding U.S. government and agency securities, the Company limits its concentration of credit risk to any single corporate issuer to 2% or less of its investment grade fixed maturities portfolio for securities rated A- or above and 1% or less of its investment grade fixed maturities portfolio for securities rated below A-.
At December 31, 2017,2019, the Company was in compliance with these limits.
(ii)     Reinsurance Recoverable Balanceson Unpaid and Paid Losses and Loss Expenses

Within the Company's reinsurance purchasing activities, itThe Company is exposed to the credit risk associated with reinsurance recoverable on unpaid and paid losses and loss expenses to the extent that any of a reinsurer failingits reinsurers fail to meet itstheir obligations under reinsurance contracts. To help mitigate this risk, the Company's purchase of reinsurance purchasing is subject to financial security requirements specified by its Reinsurance Security Committee. This Committee maintains a list of approved reinsurers, performs credit risk assessments for potential new reinsurers, regularly monitors approved reinsurers with consideration for events which may have a material impact on their creditworthiness, recommends counterparty tolerance levels for different types of ceded business and monitors concentrations of credit risk. This assessment considers a wide range of individual attributes, including a review of the counterparty’s financial strength, industry position and other qualitative factors. Generally, the Committee requires that reinsurers who do not meet specified requirements provide collateral.
At December 31, 2017,2019, the three largest balances by reinsurer accounted for 12%, 11%10% and 7% (2016:9% (2018: 13%, 10% and 9%) of reinsurance recoverable on unpaid and paid losses.

At December 31, 2017, amounts related to reinsurers with the ten largest balances comprised 56% (2016: 67%10%) of reinsurance recoverable on unpaid and paid losses and had a weighted averageloss expenses.

(iii)    Insurance and Reinsurance Premium Balances Receivable
The diversity of the Company's client base limits the credit risk associated with its insurance and reinsurance premium balances receivable. In addition, for insurance contracts the Company has contractual rights to cancel cover for non-payment of premiums and for reinsurance contracts the Company has contractual rights to offset premium balances receivable withagainst corresponding payments for losses and loss expenses.
Brokers and other intermediaries collect premiums from customers on behalf of the Company. The Company has policies and standardsprocedures in place to manage and monitor credit risk from intermediaries with a focus on day-to-day monitoring of the largest positions.
These contractual rights contribute to the mitigation of credit risk, as doestogether with the monitoring of aged premium balances receivable.

13.12.EARNINGS PER COMMON SHARELEASES


In the ordinary course of business, the Company renews and enters into new leases for office property and equipment, which expire at various dates.

At the lease inception date, the Company assesses whether a contract is or contains a lease. At the commencement date, the Company determines the classification of each separate lease component as either a finance lease or an operating lease. The Company's leases are all currently classified as operating leases. For operating leases that have a lease term of more than 12 months, the Company recognizes a lease liability and a right-of-use asset in the Company's consolidated balance sheets at the present value of the lease payments at the lease commencement date.

At the commencement date, the Company determines lease terms by assuming the exercise of those renewal options that are deemed to be reasonably certain. The exercise of lease renewal options is at the sole discretion of the Company.

As the lease contracts generally do not provide an implicit discount rate, the Company uses its incremental borrowing rate based on the information available at commencement date to determine the present value of lease payments. The incremental borrowing rate is based on a borrowing with a term that is similar to the term of the associated lease. The Company has made an accounting policy election not to include renewal, termination, or purchase options that are not reasonably certain of exercise when determining the term of the borrowing.

The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Operating lease rentals are expensed on a straight-line basis over the life of the lease beginning on the commencement date. For the year ended December 31, 2019, the total lease expense was $28 million.

Accelerated Share Repurchase Program

On August 17, 2015, the Company entered into an Accelerated Share Repurchase ("ASR") agreement with Goldman, Sachs & Co. ("Goldman Sachs") to repurchase an aggregate of $300 million of the Company's ordinary shares under an accelerated share repurchase program.

During August 2015, under the terms of this agreement, the Company paid $300 million to Goldman Sachs and initially repurchased 4,149,378 common shares. The initial shares acquired represented 80% of the $300 million total paid to Goldman Sachs and were calculated using the Company’s stock price at activation of the program. The ASR program was accounted for as an equity transaction. Accordingly, at December 31, 2015, $240 million of common shares repurchased were included as treasury shares in the Consolidated Balance Sheets with the remaining $60 million included as a reduction to additional paid-in capital.
On January 15, 2016, Goldman Sachs early terminated the ASR agreement and delivered 1,358,380 additional common shares to the Company, resulting in the reclassification of $60 million from additional paid-in capital to treasury shares. In total, the Company repurchased 5,507,758 common shares under the ASR agreement at an average price of $54.47.

The Company continually monitors and reviews its segment reporting structure in accordance with ASC 280 Segment Reporting to determine whether any changes have occurred that would impact its reporting segments.

The Company's accident and health line of business is currently included in the Company's insurance segment. During the first quarter of 2018,17, 2020, the Company plansredeemed all 9,000,000 Series D preferred shares, for an aggregate liquidation preference of $225 million (refer to realign its accident and health line of business. As a result of the realignment, this business will also be included in the Company's reinsurance segment.Note 14 'Shareholder's Equity').


The alignment of the Company's accident and health line of business will impact the presentation of the Company's reporting segments. Work is ongoing to recast the Company’s current and prior periods within its financial systems to conform to the new presentation. The Company expects to complete this work during the first quarter of 2018 and to reflect the results of its accident and health business in the Company's insurance and reinsurance segments for the three month period ended March 31, 2018.

Management’s Annual Report on Internal Control Over Financial Reporting
The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act). The Company’s management has performed an assessment, with the participation of the Company’s Chief Executive Officer and the Company’s Chief Financial Officer, of ourthe Company's internal control over financial reporting at December 31, 2017.2019. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013).
Based uponon that assessment, the Company’s management believes that, at December 31, 2017, our2019, the Company's internal control over financial reporting is effective to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.
In conducting our assessment of the effectiveness of our internal control over financial reporting at December 31, 2017, we have excluded an assessment of the effectiveness of the Company’s internal control over financial reporting related to the acquisition of Novae Group plc ("Novae") as permitted by the guidance issued by the Office of the Accountant of the Securities and Exchange Commission (not to extend one year beyond the date of acquisition or one annual reporting period). The Company acquired the entire issued and to be issued share capital of Novae on October 2, 2017. For the year ended December 31, 2017, Novae's assets represented 13.5 percent of consolidated assets, Novae's revenues represented 4.2 percent of consolidated revenues, and Novae's net loss represented 1.4 percent of consolidated net loss. See Note 3 for further discussion of this acquisition and its impact on the Company's consolidated financial statements.
Our independent registered public accounting firm has issued an audit report on ourmanagement's assessment of ourthe Company's internal control over financial reporting at December 31, 2017.2019. This report appears below.
All internal control systems, no matter how well designed, have inherent limitations. As a result, even those internal control systems determined to be effective can provide only reasonable assurance with respect to financial reporting and the preparation of financial statements.
Changes in Internal Control Over Financial Reporting
The Company’s management has performed an evaluation, with the participation of the Company’s Chief Executive Officer and the Company’s Chief Financial Officer, of changes in the Company’s internal control over financial reporting that occurred during the quarter ended December 31, 2017.2019. Based uponon that evaluation, there were no changes in ourthe Company's internal control over financial reporting that occurred during the quarter ended December 31, 20172019 that have materially affected, or are reasonably likely to materially affect, ourthe Company's internal control over financial reporting.




REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of
AXIS Capital Holdings Limited

Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of AXIS Capital Holdings Limited and subsidiaries (the “Company”) as of December 31, 2017,2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2017,2019, of the Company and our report dated February 28, 201827, 2020 expressed an unqualified opinion on those financial statements.
As described in Management's Annual Report on Internal Control Over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Novae Group plc (“Novae”), which was acquired on October 2, 2017 and whose financial statements constitute 13.5% of assets, 4.2% of revenues, and 1.4% of net loss of the consolidated financial statement amounts as of and for the year ended December 31, 2017. Accordingly, our audit did not include the internal control over financial reporting at Novae.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Controls Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

ITEM 9B.OTHER INFORMATION

Disclosure of Certain Activities Under Section 13(r) of the Securities Exchange Act of 1934

Section 13(r) of the Securities Exchange Act of 1934, as amended, requires issuers to disclose in their annual and quarterly reports whether they or any of their affiliates knowingly engaged in certain activities with Iran or with individuals or entities that are subject to certain sanctions under U.S. law. Issuers are required to provide this disclosure even where the activities, transactions or dealings are conducted outside of the U.S. in compliance with applicable law.

As and when allowed by the applicable law and regulations, certain of our non-U.S. subsidiaries provide treaty reinsurance coverage to non-U.S. insurers on a worldwide basis, including insurers of liability, marine, aviation and energy risks, and as a result, these underlying reinsurance portfolios may have some exposure to Iran. In addition, we underwrite insurance and facultative reinsurance on a global basis to non-U.S. insureds and insurers, including for liability, marine, aviation and energy risks. Coverage provided to non-Iranian business may indirectly cover an exposure in Iran. For example, certain of our operations underwrite global marine hull and cargo policies that provide coverage for vessels navigating into and out of ports worldwide, including Iran. For the quarter ended December 31, 2017,2019, there has been no material amount of premium allocated or apportioned to activities relating to Iran. As we believe these activities are permitted under applicable laws and regulations, we intend for our non-U.S. subsidiaries to continue to provide such coverage to the extent permitted by applicable law.

(1)We evaluate theThe Company evaluates underwriting results of each of ourits reportable segments separately from the performance of ourits investment portfolio. As such, we believeportfolio therefore, the Company believes it is appropriate to exclude net investment income from ourits underwriting profitability measure.
(2)
Amounts related to ourthe Company's reportable segments reflect underwriting-related general and administrative expenses, which includes those general and administrative expenses that are incremental and/or directly attributable to our individualthe Company's underwriting operations. Underwriting-related general and administrative expenses is a non-GAAP financial measure as defined in Item 10(e) of SEC Regulation S-K. The reconciliation to general and administrative expenses, the most comparable GAAP financial measure, presented in the table above, also included corporate expenses of $129 million, $108 million and $130 million for the years ended December 31, 2019, 2018 and 2017, respectively. Corporate expenses include holding company costs necessary to support our worldwide insurance and reinsurance operations and costs associated with operating as a publicly-traded company. As these costs are not incremental and/or directly attributable to our individualthe Company's underwriting operations, we exclude themthese expenses are excluded from underwriting-related general and administrative expenses. The reconciliation of underwriting-related general and administrative expenses to general and administrative expenses, the most comparable GAAP measure, is presented in Item 7 'Management’s Discussion and Analysis of Financial Condition and Results of Operations – Executive summary, Results of Operations'.
