Overview

Selective Insurance Group, Inc. (referred to as the “Parent”(“Parent”) is a New Jersey holding company that was incorporated in 1977. Our main office is located in Branchville, New Jersey1977 that owns ten property and the Parent’s common stock is publicly traded on the NASDAQ Global Select Market under the symbol “SIGI.” The Parent has tencasualty insurance subsidiaries nine of which are licensed by variousthat sell products and services only in the United States ("U.S."). Various state departments of insurance (i) license nine of our subsidiaries as admitted carriers to write specific lines of property and casualty insurance business in the standard market. The remainingmarketplace and (ii) authorize the tenth subsidiary is authorized by various state insurance departmentsas a non-admitted carrier to write property and casualty insurance in the excess and surplus ("E&S") lines market. OurWe refer throughout this document to our ten insurance subsidiaries are collectively referred to as the “Insurance Subsidiaries.” TheSubsidiaries” and to the Parent and its subsidiaries arethe Insurance Subsidiaries collectively referred to as "we," “us,” or “our”“our.” We make limited use of Parent as necessary to distinguish the holding company from the Insurance Subsidiaries.

Our main office is located in this document.

Branchville, New Jersey. Our common and preferred stock are listed and traded on the NASDAQ Global Select Market under the symbols “SIGI” and "SIGIP," respectively. In 2017, we were2020, AM Best Company (“AM Best”) ranked us as the 36th38th largest property and casualty group in the United States based on 2016 net premiums written (“NPW”) in A.M. Best Company’s (“A.M. Best”)its annual list of “Top 200 U.S. Property/Casualty Writers.Writers, based on 2019 net premiums written (“NPW”). Since our founding in 1926, we have a long and successful history in the property and casualty industry, including an "A" or higher AM Best financial strength rating for the past 90 years.


The property and casualty insurance market is highly regulated and competitive with fragmented market share, andparticularly in standard commercial lines. The market has three main distribution methods: (i) sales through appointed independent insurance agents; (ii) direct sales to personal and commercial customers;customers, including, but not limited to, internet-based platforms; and (iii) a combination ofsales through captive insurance agents employed by or contracted to sell exclusively with one insurance company. We distribute our property and casualty products exclusively through independent agent and direct sales. In this highlyinsurance agents.

Strategic Advantages
We have three key sustainable competitive and regulated industry, we have several strategic advantages as follows: advantages:

(i) the true franchise value we have built through our relationships with a small group of distribution partners that we refer to as our "ivy league" independent distribution partners, who collectively have significant market share in the states in which we operate and from whom we expect to gain increasing percentages of the business they write; (ii) ourA unique field model in which our underwriting claims, and safety management personnel are located in the same communitiesgeographic territories they serve, and a claims operation that specializes regionally and dedicates resources locally to manage our customer relationships. We enhance our field model with sophisticated tools and technologies to inform underwriting, pricing, and claims decisions;

(ii) A franchise value distribution model in which we focus our independent insurance agency appointments to a small number of high quality partners with whom we have longstanding and close business relationships; and

(iii) A superior omnichannel customer experience provided by best-in-class employees, enhanced by digital platforms and value-added services to increase customer engagement.

We are rated by nationally recognized statistical rating organizations ("NRSROs") that issue opinions on our financial strength, operating performance, strategic position, and ability to meet policyholder obligations. We believe that our ability to write insurance business is most influenced by our AM Best rating. In the fourth quarter of 2020, AM Best reaffirmed (i) our rating of "A (Excellent)," the third highest of their 13 financial strength ratings, and (ii) our outlook of "positive."

Our Insurance Subsidiaries’ ratings by NRSRO are as ourfollows:

AM BestAPositive
Standard & Poor’s Global Ratings (“S&P”)AStable
Moody’s Investors Services (“Moody’s”)A2Stable
Fitch Ratings (“Fitch”)A+Stable

Our independent distribution partners contemplate financial strength ratings when recommending insurance carriers to customers, and customers supported by sophisticated analytics, technology, and regional and home office support; and (iii) our focus on service and providing an exceptional and personalized customer experience that is seamless regardless of whether the method of communication is on-line, over the phone, or in person with onemany of our distribution partners. We refer to this as our omni-channel customer experience.

We have defined a long-term financial goal to achieve a non-GAAP operating return on equity of 300 basis points over our weighted-average cost of capital. For further details regarding our 2017 performance as it relates to return on equity, refer to "Financial Highlights of Results for Years Ended December 31, 2017, 2016, and 2015"customers also contemplate them in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations." of this Form 10-K.

Financial Strength Ratings play a significant role in insurancetheir purchasing recommendations by our distribution partners and in decision-making by our customers.decisions. Distribution partners generally recommend higher rated carriers to limit their potential liability for error and omission claims, andclaims. Most of our customers often have minimum insurer rating requirements in loanloans, mortgages, and other banking covenantsagreements securing real and personal property.

These NRSROs also rate our long-term debt creditworthiness. Credit ratings indicate the ability of debt issuers to meet obligations in a timely manner and are important factors in our overall funding profile and ability to access certain types of liquidity.

We have provided a glossary of terms as Exhibit 99.1 to this Form 10-K, which defines certain industry-specific and other terms that are used in this Form 10-K.



Human Capital

We recognize that sustainable human capital complements and contributes to superior longer-term financial performance. We are committed to maintaining a safe and inclusive workplace that promotes diversity and provides attractive benefits to our approximately 2,400 employees. In 2020, we were designated as a Great Place to Work CertifiedTM organization, with 91% of employees identifying us as a great place to work. We discuss our approach to (i) physical, financial, and social well-being of our employees; (ii) talent development and employee retention; and (iii) diversity and inclusion more fully below.

Physical, Financial, and Social Well-Being of our Employees
We invest significantly in our employees' physical, financial and social well-being, which is essential to retaining the best talent. We regularly analyze and adjust compensation to ensure both internal equity and external market alignment. To support the financial well-being of our employees and their families, we offer competitive financial benefit programs, including a 401(k) plan with both employer and employer matching contributions, an employee stock purchase plan with the opportunity to purchase company stock at a discount, a tuition reimbursement program, and a student loan repayment program. To promote the health and well-being of our employees, we also offer competitive and convenient health and wellness programs. We also support the social well-being of our employees, encouraging them to be connected with their colleagues and communities through various programs, such as paid time-off for volunteer work and matching charitable donations.

Talent Development and Employee Retention
We invest significant time and resources on training and development to assist our employees in fulfilling their professional potential and having rewarding careers. We are committed to ongoing learning, personal growth, and continuous improvement. Our employees have access to a variety of live instructor-led training courses and extensive online skills training courses and resources. We also have leadership and talent development programs and initiatives at all levels of the organization. Among these are our Next Generation of Leaders program, through which we identify internal leaders on whom we focus development opportunities so they will be well prepared to lead us in the future. We continue to focus on talent development programs and employee retention. For the year, our employee turnover rate was approximately 7%. Employees with over 20 years of service represented approximately 17% of all employees. In 2019, Forbes recognized us as one of "America's Best Midsize Employers."

Diversity and Inclusion
We recognize that when employees with diverse cultural backgrounds, ideas and experiences work together, it fosters innovation. We have initiatives to increase representation and cultivate greater inclusion of people with differences in gender, ethnicity, race, age, sexual orientation, gender identity, and socio-economic background. We have taken steps to (i) promote greater diversity in first-level management positions to create a pipeline to increase future diversity in senior and executive leadership, and (ii) increase members of our Board of Directors ("Board") who have diverse backgrounds with a wide range of skills and experience, including the addition of three directors who are Black and Latinx.

As of December 31, 2020, women represented 57% of our non-officer workforce and 31% of our officer workforce. We have three women on our Board, and increasing the representation of women in senior management roles is a prioritized goal. Our ethnic diversity for officers and non-officers is consistent with the national average for financial services, but our objective is to increase this representation over time. Currently, approximately 82% of our workforce is White; and 18% of our workforce is a combination of Black, Latinos, Asians, and all other ethnicities combined.

Coronavirus ("COVID-19") Pandemic
Our strategic competitive advantages described above, strong financial position, effective operations, and experienced leadership team have positioned us well to address the ongoing challenges of COVID-19. During the year, governmental (international, federal, state, and local) actions to contain or delay the spread of COVID-19 resulted in directives requiring social distancing, operational alteration or temporary closure of most non-essential businesses, and the “sheltering-in-place” of many non-essential workers. Under most governmental directives, insurance is considered an essential business. Our information technology ("IT") infrastructure and security, which previously supported over 675 home-based employees, made for a smooth and effective transition of all of our office-based employees to a temporary work-from-home environment, while still maintaining expected customer and agent service levels. Most of our local independent distribution partners also transitioned to a remote work environment. Our strong relationships with — and continued support for — them enabled us to successfully maintain the excellent service-levels we delivered pre-pandemic, for claims handling, underwriting, premium audit processes, and safety management services.

Because most employees have been working remotely since March 2020, we have changed some regular communication methods and increased video conferencing and collaboration tools on robust and secure applications. Throughout 2020, our President and Chief Executive Officer hosted regular company-wide virtual town hall meetings to provide organizational updates and address areas of general employee concern. To keep our employees fully informed about COVID-19-related developments, we (i) disseminated regular health, safety, and other communications, (ii) established an on-line coronavirus center with information, links to valuable resources, and helpful videos, and (iii) continued our pre-COVID-19 online “pulse surveys” to gauge employees’ views on various issues. Our employees have rated our communications around COVID-19 positively.

Our methods to communicate with customers, prospects, agents, and vendors generally have shifted towards digital and virtual platforms. Our underwriting, claims, premium audit, and safety management functions have replaced their former typically in-person meetings with virtual or video-enabled interactions, although some limited site visits still occur. To ensure we maintain providing a superior omnichannel customer experience as one of our three key strategic advantages, we have developed the ability to respond to our customers in their preferred method of communication — whether by phone, email, or social media.

Our internal operations continue to function effectively during COVID-19. We continue to process claims, underwrite our policies, and operate our corporate functions at the same high standards to which we have always adhered. We effectively managed the implementation of various customer support initiatives during this challenging time, including (i) billing accommodations for our customers that we announced in early 2020, coupled with the implementation of certain state-specific regulations that provided for the deferral of premium payments without cancellations for up to 90 days, and (ii) a credit to our personal and commercial automobile customers with in-force policies equivalent to 15% of their April and May premiums due to the unprecedented nature of the government directives and the associated favorable claims frequency impact.

We entered the COVID-19 pandemic in the strongest financial position in our history, with a high level of embedded profitability in our underwriting and investment portfolios, and strong financial strength ratings. This positioned us well to withstand the COVID-19-related economic downturn, market volatility and heightened uncertainty. For further information regarding the financial impacts of COVID-19, refer to Item 7. “Management's Discussion and Analysis of Financial Condition and Results of Operations.” of this Form 10-K. Additionally, for more information on the COVID-19-related impacts on our control environment, see the "Enterprise Risk Management" discussion below.

Segments


We classify our business intohave four reportable segments, which are as follows:segments:
Standard Commercial Lines, which represents 74% of consolidated revenues, is comprised of property and casualty insurance products and services provided in the standard marketplace to commercial enterprises, which areenterprises; typically businesses, non-profit organizations, and local government agencies.

We currently only write commercial lines E&S coverages and thiscoverages. This business representsrepresented 9% of our total insurance operations’ NPW in 2020, and is sold in all 50 states and the District of Columbia. The average premium per policyholder in 2020 was approximately $3,100.


Investments, which represents 8% (including net realized and unrealized gains and losses) of consolidated revenues, invests the premiums collected by our insurance operations as well asand amounts generated through our capital management strategies, which includesinclude the issuance of debt and equity securities.


We derive substantially all of our income in three ways:


Underwriting income/loss from our insurance operations. Underwriting income/loss is comprised of revenues, which are the premiums earned onfrom our insurance products and services, less expenses. Gross premiums are direct premium written (“DPW”)DPW plus premiums assumed from other insurers. GrossNPW is equal to gross premiums less premiumpremiums ceded to reinsurers, is NPW.reinsurers. NPW is recognized as revenue ratably over a policy’s term as net premiums earned (“NPE”).

Expenses related to our insurance operations fall into three main categories:categories, which are depicted on our Consolidated Statements of Income: (i) "Loss and loss expense incurred," which includes losses associated with claims and variousall loss expenses incurred for adjusting claims (referred to as “loss and loss expense”);incurred during a policy's term; (ii) "Amortization of deferred policy acquisition costs," which includes expenses related to the successful acquisition of insurance policy issuance,policies, such as commissions to our distribution partners and premium taxes, and otherare recognized ratably over a policy's term; and (iii) "Other insurance expenses," which includes acquisition expenses not captured above, as well as expenses incurred in issuing and maintaining policies including employee compensation and benefits (referred to as “underwriting expenses”); and (iii) policyholder dividends.


Total underwriting expenses are the total of Amortization of deferred policy acquisition costs and Other insurance expenses, offset by Other income on our Consolidated Statements of Income. Other income primarily includes installment fees, which are fees charged to customers paying their premiums on an installment basis.

Net investment income from theour investment segment. We generate income from investing insurance premiums and amounts generated through our capital management strategies. Net investment income consists primarily of:of (i) interest earned on fixed income investments and preferred stocks;commercial mortgage loans, (ii) dividends earned on equity securities;securities, and (iii) other income primarily generated from our alternative investment portfolio.


Net realized and unrealized gains and losses on investment securities from theour investments segment. Realized gains and losses from theour investment portfolios of the Insurance Subsidiaries and the Parent are typicallyportfolio is the result of (i) security disposals through sales, calls, and redemptions. Theyredemptions, (ii) losses on securities for which we have the intent to sell, (iii) credit loss expense or benefit, and (iv) net unrealized gains and losses on equity securities.

Net income (or loss) available to common stockholders on our Consolidated Statements of Income also include write downs from other-than-temporary impairments (“OTTI”).

Our income is partially offset by:includes (i) corporate expenses, atwhich includes expenses of the Parent that includeconsisting of long-term incentive compensation to employees, and other general corporate expenses, (ii) interest on our debt obligations, and other general corporate expenses; and (ii)(iii) federal income taxes.taxes, and (iv) dividends to preferred shareholders.


We use net income (or loss) available to common stockholders and non-GAAP operating income as measures of financial performance. Non-GAAP operating income differs from net income available to common stockholders by the exclusion of (i) after-tax net realized and unrealized gains and losses on investments, and (ii) after-tax debt retirement costs.

We use combined ratio as the key performance measure in assessing the performance of our insurance operations. The combined ratio is calculated by adding:adding (i) the loss and loss expense ratio, which is the ratio of incurred loss and loss expense to NPE;NPE, (ii) the expense ratio, which is the ratio of underwriting expenses to NPE;NPE, and (iii) the dividend ratio, which is the ratio of policyholder dividends to NPE. A combined ratio under 100% indicates an underwriting profit, and a combined ratio over 100% indicates an underwriting loss. The combined ratio does not reflect investment income, federal income taxes, or Parent company income or expense. The loss and loss expense ratio is typically the largest contributor to our combined ratio and key drivers are the amount of catastrophe and non-catastrophe property loss and loss expenses incurred, current year casualty loss estimates, and the impact of prior year casualty reserve development.

7



We principally use after-tax net investment income and net realized gains or losses as the key measuresmeasure in assessing the financial performance of our investments segment. We also assess total return, which we calculate by adding pre-tax net realized and unrealized investment gains or losses (including losses on securities we intend to sell and credit loss expense or benefit) to pre-tax net investment income. Our investment philosophy includes setting certain risk and return objectives for the fixed income, equity, and other investment portfolios. We generally review our performance byportfolios and comparing our returns for each of these components of our portfolio to a weighted-average benchmark of comparable indices.




For revenueWe also use return on common equity ("ROE") and profitabilitynon-generally accepted accounting principles operating return on common equity ("non-GAAP operating ROE") as important measures for each of our overall financial performance. ROE is a profitability measurement calculated by dividing net income available to common stockholders by average common stockholders' equity during the period. Non-GAAP operating ROE is calculated by dividing non-GAAP operating income available to common stockholders by average common stockholders' equity during the period. We evaluate our segments, seein part, based on their contribution to non-GAAP operating ROE. We establish our non-GAAP operating ROE target annually based on (i) our current estimated weighted average cost of capital, (ii) the current interest rate environment, and (iii) property and casualty insurance market conditions. For 2021, our non-GAAP operating ROE target is 11%. For further details regarding our 2020 performance as it relates to ROE, refer to "Financial Highlights of Results for Years Ended December 31, 2020, 2019, and 2018" in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations." of this Form
10-K.

In addition to measuring and monitoring our results by segment using combined ratio and non-GAAP operating ROE metrics, we also monitor key operating leverage metrics, such as NPW to surplus and invested assets per dollar of common stockholders’ equity.
We believe we have a lower financial risk profile and strong financial strength compared to the industry driven by:

Our Standard Commercial Lines segment underwriting risk appetite, which is focused on small-to-medium sized accounts, with risks generally characterized as low-to-medium hazard. Our average premium per policyholder is approximately $12,900, with about 87% of our casualty lines business in this segment having limits of $1 million or less (excluding workers compensation policies, as they do not have limits);

Maintaining sophisticated pricing reviews and disciplined financial planning and reserving practices. The latter includes quarterly ground-up reserve reviews for principally all lines of business, semi-annual independent external reserve reviews, and year-end regulatory actuarial reserve opinions issued by an independent external actuary;

Purchasing significant levels of reinsurance, including a property catastrophe reinsurance program that limits the net after-tax impact of a 1 in 250 year catastrophe to about 4% of our U.S. generally accepted accounting principles ("GAAP") equity and property and casualty excess of loss reinsurance agreements that limit the impact of individual property and casualty claims to $2 million per risk and $2 million per occurrence, respectively; and

Maintaining a conservative investment portfolio principally invested in high quality and liquid fixed income and short-term investments with a modest allocation to risk assets.

As a result of our strong financial strength and lower financial and underwriting risk profile, we operate with higher operating leverage than the industry as a whole. We define operating leverage as the ratio of NPW to policyholders' surplus, and we target a ratio between 1.35x and 1.55x. Our operating leverage at December 31, 2020 was 1.30x, compared to the U.S. standard commercial and personal lines industry average of approximately 0.7x, as reported in Conning, Inc.'s Fourth Quarter 2020 Property-Casualty Forecast & Analysis.

Our higher operating leverage results in higher investment leverage than the industry. We define investment leverage as invested assets per dollar of common stockholders’ equity. Our investment leverage at December 31, 2020 was $2.96 compared to the U.S. commercial and personal lines average invested assets to surplus of $2.07. Because we have higher investment leverage, we have adopted a conservative investment management philosophy with fixed income securities and short-term investments, representing more than 92% of our invested assets. These fixed income securities and short-term investments currently have a weighted average credit rating of "AA-" and an effective duration of 3.8 years. Subject to economic and market conditions; however, we expect to modestly increase our exposure to credit risk within our fixed income securities portfolio by continuing to reinvest proceeds from the non-sale disposal activity primarily related to "AAA" rated agency-backed residential mortgage-backed securities ("RMBS") into other high quality, but non-AAA rated fixed income sectors, as we find the risk adjusted returns more attractive. Over the coming quarters, we expect the average credit rating will decrease from "AA-" to "A+" and remain there for the foreseeable future; however, we do not anticipate a material shift in the overall risk/return characteristics of our fixed income securities portfolio. For additional information about the design and

credit quality characteristics of our investment segment, refer to "Credit Risk" in Item 7A. "Quantitative and Qualitative Disclosures About Market Risk." and Note 11. "Segment Information"5. "Investments" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

Our strategy of operating with higher operating and investment leverage than the industry as a whole allows us to generate more ROE from our underwriting and investment portfolios. We do not allocate assetsgenerate 0.9 points of ROE for each point on the combined ratio, and 2.4 points of ROE for each point of pre-tax investment yield. This allows us to individual segments. In addition,generate strong returns for analysis of segments' results, see "Results of Operationsour shareholders and Related Information by Segment"we believe it is a competitive advantage, particularly in Item 7.

As part of our risk management efforts associated with the sale of our products and services, we use reinsurance to protect our capital resources and insure us against losses on the risks that we underwrite. We use two main reinsurance vehicles: (i) a reinsurance pooling agreement among our Insurance Subsidiaries in which each company agrees to share in premiums and losses based on certain specified percentages; and (ii)enter into reinsurance contracts and arrangements with third parties that cover various policies that we issue to our customers. In addition, to protect our Insurance Subsidiaries, we maintain an internal reinsurance pooling agreement in which each company shares in premiums and losses based on certain specified percentages. For information regarding reinsurance treaties and agreements, see "Reinsurance" in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations." of this Form 10-K.

Insurance Operations
Products and Services
The types of insurance we sell in our insurance operations fall into two broad categories:


Property insurance, which generally covers the financial consequences of accidental loss of an insured’s real and/or personal property. Property claims are generally reported and settled in a relatively short period of time.

Casualty insurance, which generally covers the financial consequences of (i) employee injuries in the course of employment, and(ii) bodily injury and/or property damage to a third party as a result of an insured’s negligent acts, omissions, or legal liabilities.liabilities, and (iii) the obligation to defend our insured(s). Casualty claims have long tails and may take several years and, forin some casualty claimssituations, even several decades to be reported and settled.


We underwrite our businessProperty insurance, which generally covers the financial consequences of accidental loss of an insured’s real and/or personal property or earnings. Property claims are generally reported and settled in a relatively short period of time.

Product Development and Pricing
Our insurance policies are contracts with our policyholders that specify our coverages - whatthe losses we cover and the amounts we will pay to or for an insured uponon a specifiedcovered loss. We develop our coverages internally and by (i) adopting and modifyingpolicy forms andcreated or filed by statistical data licensed fromrating agencies or other third party aggregators,parties, notably Insurance Services Office, Inc. (“ISO”), American Association of Insurance Services, Inc. ("AAIS"), and the National Council on Compensation Insurance, Inc. ("NCCI")., (ii) independently creating our own policy forms, or (iii) modifying third-party policy forms. In developing products and services, we consider market demands, based on competitive research and feedback from our independent distribution partners, and the potential impact the product or service will have in making our customer’s commercial or personal endeavors safer.

Our policies provide coverage for future events, so the actual individual policy loss costs are unknown at the point of sale. Determining pricing for coverage requires us to consider many variables. Like most property and casualty insurance companies, our loss data alone is not sufficiently credible to independently establish the price to chargecomplex sets of loss costs and rating variables required for our coverages involves considerationproducts. Therefore, we often adopt loss costs and rating structures filed by statistical rating agencies, such as ISO and NCCI. We typically modify these loss costs or factors based on actuarial analyses of many variables. At the time we underwrite and issue a policy, we do not know what our actual costs for the policy will be in the future. To calculate and project future costs, we examine and analyzeown historical statistical data, and factor in expected changesto the extent that data is credible, factoring in loss trends. Additionally,trends and other expected impacts. The resulting loss costs are converted to premium rates, by adding in provisions for our company expense and profit. In some cases, we supplement the indicated rates with competitive market information to determine our final selected rates.

We have developed predictive models for certainmany of our Standard Commercial and Standard Personal Lines.Lines, which we use to further refine the statistical rating agencies' rating plans, or to independently develop our own plans. Predictive models analyze historical statistical data regardingrelated to various risk characteristics that drive loss experience. For our customers and their loss experience, rankStandard Commercial Lines, we use the output of these models to group our policies, or potential policies, based on this analysis,their expected loss potential, which serve as input into the underwriting and apply this risk datapricing process for individual risks. For our Standard Personal Lines, we use these models to current and future customers to predictdevelop factors in our filed rating plans. In all cases, the likely profitability of an account. A model’s predictive capabilities of these models are limited bydependent on the amountquantity and quality of theavailable statistical data available. As a super-regional insurance group, our loss experience is not always statistically large enough to analyze and project future costs. Consequently,data. Therefore, we use ISO, AAIS, and NCCI data tomay supplement our proprietary data.them with other competitive market information or underwriting judgment.


Customers and Customer Markets

We do not categorize our Standard Personal LineLines customers or our E&S LineLines customers by SBU.

The following are general guidelines that can be used as indicators of the approximate size of our customers:
The average Standard Commercial Lines account size is approximately $11,000.
The average Standard Personal Lines account size is approximately $2,000.
The average E&S Lines policy is approximately $3,000.

No one customer accounts for 10% or more of our insurance operations in the aggregate.


We manage volatility in our underwriting results, in part, by writing accounts that have a lower limits profile. The table below illustrates the percentage of accounts with total insured value and exposure limits at and below $1 million for property and casualty insurance accounts, respectively:
PropertyCasualty
Standard Commercial Lines78%
 87%1
Standard Personal Lines84%98%
E&S Lines97%98%
1Standard Commercial Lines excludes policies written in our workers compensation line of business, which do not have statutory policy limits, but are covered by our casualty excess of loss treaty, which provides coverage for losses above $2 million.

We also purchase significant levels of reinsurance from reinsurers with an average credit rating of "A" or better. Our reinsurance program supports our ability to write accounts with larger policy limits by limiting the impact of individual property and casualty losses to $2 million per risk and $2 million per occurrence, respectively.

Geographic Markets
We principally sell our insurance products and services in the following geographic markets:


Standard Commercial Lines products and services are primarily sold in 2527 states located in the Eastern, Midwestern, and Southwestern regions of the United StatesU.S. and the District of Columbia. In January 2018, we entered Colorado, and we expect to add New Mexico and Utah later this year. This will bring our total Standard Commercial Lines states to 27 by the end of 2018.

Distribution Channel
We sell our insurance products and services through the following types of independent distribution partners:


Standard Commercial Lines: independentIndependent retail agents;

Standard Personal Lines: independentIndependent retail agents; and

E&S Lines: wholesaleWholesale general agents and brokers.agents.


We generally pay our distribution partners commissions that are based oncalculated as a percentage of direct premiums written, and in some cases are furtherDPW, often supplemented by amounts based on profit calculations, andprofitability or other considerationconsiderations for business placed with us. We seek to compensate them fairly and in a manner consistentconsistently with market practices. No one independent distribution partner is responsible for 10% or more of our combined insurance operations' premium. Our top 20 distribution partners generated approximately 27%36% of our NPWDPW, excluding the flood line of business, in 2017, with 19 of the 20 being larger agency groups.2020.

As our customers rely heavily on our distribution partners, it is sometimes difficult to develop brand recognition as these customers cannot always differentiate between their insurance agents and their insurance carriers. We continue to evolve our service model, post policy-acquisition, with an increasing focus on the customer. Our goal is to provide our customers with 24/7 access to transactional capabilities and account information. Customers expect this level of access from every business and, while many insurers offer such solutions in the personal lines space, we want to be a leader in this area for our entire book of business. When combined with our digital strategy, we believe this level of access will significantly improve the customer experience. Within our digital strategy, we provide self-servicing capabilities via a mobile application and a web-based portal where our customers have access to basic account information on demand. These efforts will allow us to continue to offer customers a shared experience with our distribution partners, while positioning us to more directly demonstrate our value proposition.




Independent Retail Agents
According to a study released in 2017 by theA 2020 Independent Insurance Agents & Brokers of America study reported that independent retail insurance agents and brokers write approximately 83%85% of standard commercial lines insurance and 36% of standard personal lines insurance in the United States.U.S. We believeexpect that independent retail insurance agents, which comprise the bulk of our independent distribution partners, will remain a significant force in overall insurance industry premium production because they generally represent more than onemultiple insurance carrier and therefore are able to providecarriers. This provides the customer with a wider choice of commercial and personal lines insurance products, more competitive pricing, and individualized risk-based consultation to customers.consultation.


We currently have 1,250 independent retail agentsapproximately 1,400 distribution partners selling our Standard Commercial Lines business, 685and 850 of whichthese distribution partners also sell our Standard Personal Lines business (excluding flood). In total, these 1,250business. These 1,400 distribution partners sell our products and services through approximately 2,400 office locations. We also have approximately 2,350 office locations selling our business. In addition, we have approximately 5,800 retail agents6,000 distribution partners selling our flood insurance products.

In a 2017 survey, we received an overall satisfaction score of 8.8 out of 10 from our standard market distribution partners, which, we believe, highlighted their satisfaction with our products, the ease of reporting claims, and the professionalism and effectiveness of our employees.

Wholesale General Agents
Our distribution partners for our E&S Lines are written almost exclusively through 8590 wholesale general agents and 9 wholesale brokers with a combined 245300 office locations, who are our distribution partners in the E&S market.locations. We have granted limited binding authority to thethese wholesale general agents for businessrisks that meetsmeet our prescribed underwriting and pricing guidelines. The wholesale brokers submit brokerage business to us for risk acceptability, terms and conditions, and pricing.


Marketing
Our primary marketing strategy is to:

Innovation
To advance (i) an organizational culture of innovation, (ii) our nimbleness, (iii) our digital and customer experience initiatives, and (iv) our long-term value proposition to our customers and distribution partners, we terminatedhave undertaken several important strategic actions. We:

Created a team dedicated to innovation and continuous improvement under a chief innovation officer. This team was established to (i) apply proven innovation techniques and methods for identifying, prioritizing, and advancing strategic innovative ideas and opportunities, (ii) stay abreast of the key industry and insurance technology trends that impact our customers, distribution partners, and employees, and (iii) further expand our culture of innovation by providing training and skill-building opportunities, facilitating departmental and cross-functional strategy and innovation sessions, and leading relevant communities of interest that intersect with the lifecycle of innovation;

Opened an existing vendor.innovation lab at our corporate headquarters to spur innovation generally and further our efforts to identify and deploy product, agency and customer experience, and operational efficiency improvements; and

High TouchEstablished an Insurtech Investment Committee to review and take action on potential investment opportunities in technology and Insurtech vehicles that may positively impact our business or the industry.

These efforts position us to offer customers an improved service experience and better position us to demonstrate our long-term value proposition to our customers and distribution partners.

Our digital and customer experience initiatives have helped us introduce the following solutions:

SelectiveGOSM - a free-to-customer driving mobile application that we launched in late 2020 to our Standard Personal Lines customers in certain states, which provides driver performance features to help customers improve their driving with detailed feedback on speeding, harsh braking, rapid acceleration, and more.

Selective® Drive - a free-to-customer, commercial vehicle fleet management tool that we launched in 2019 that detects unsafe driving behaviors and provides additional information to help our customers manage their vehicles and drivers.

In addition, during the second half of 2020, we began rolling out a new platform within our Standard Commercial Lines segment designed to streamline the quoting and issuance of new small business policies for our distribution partners. We generally consider small business to be lower hazard business in specific industry classifications with premiums less than $25,000. Writing small business has always been a core part of our strategy. Technology, as well as the number of market participants in this space, has been advancing rapidly in recent years. We launched a multi-year strategy with an emphasis on improving the ease and speed of writing small business, and are reinforcing our commitment to our distribution partners in this market by offering a best-in-class small business experience. We are advancing the user experience of our rating platform by streamlining the amount of information required to generate a quote. This new small business platform has been deployed for

our businessowners' policies and commercial automobile lines of business. The enhanced system allows our agents to quote and issue over 400 businessowners' classes, including Professional Offices, Florists, Technology, and Funeral Homes. Our plans include adding additional capabilities and more lines of business in 2021 to help us maximize new business growth and share of small business with our distribution partners.

Field Model
To support our independent distribution partners, we employ a unique field model for bothin which (i) our Standard Commercial Lines underwriting and claims, with various employeessafety management personnel are located in the geographic territories they serve and (ii) our claims operation is organized regionally by claim specialty with local resources who manage our customer relationships. This field usually working from home offices near our distribution partners. We believe that we buildmodel builds better and stronger relationships with our independent distribution partners because of thedue to our field employees' close proximity of our field employees, and the resulting direct interaction with them and our distribution partnerscustomers. We enhance the field model with our sophisticated tools and customers.technologies to inform underwriting, pricing, safety management, and claims decisions. At December 31, 2017,2020, we had approximately 2,2602,400 employees, of which 560 workedwhom 675 are normally home-based, 950 are in the field, 860 worked in one of our regional offices, and the remainder workedare in our corporate office. Currently, as a result of the COVID-19 pandemic, the majority of our office-based employees are temporarily working remotely from home.

Renewal business is underwritten in each Region, but some business is renewed in our underwriting service center ("USC"), where underwriters are assigned to specific agents. With this model, production resources are focused on new opportunities with our agents, which provides capacity for the best profitable growth opportunities. In addition, our separate group of renewal underwriters remain focused on retaining our best accounts and profitability of business that their assigned distribution partners write with us; and (ii) perform field underwriting for new Standard Commercial Lines business;driving profit improvement goals within the portfolio.

Our territory managers who have oversight of the AMS production team for Standard Commercial Lines, ensure that: (i) annual profit and growth plans are developed on a state by state basis; (ii) the achievement of these state plans are monitored at the state, AMS territory and account level; and (iii) individual agency plans are developed and monitored for achievement annually;

Our E&S territory managers, who have primary responsibility for identifying new opportunities to grow our E&S Lines.

We have an underwriting service center (“USC”) located in Richmond, Virginia. The USC assists our distribution partners by servicing certain Standard Personal Lines and smaller Standard Commercial Lines accounts. At the USC, many of our employees are licensed agents who respond to customer inquiries about insurance coverage, billing transactions, and other matters. For the convenience of using the USC and our handling of certain transactions, our distribution partners agree to receive a slightly lower than standard commission for the premium associated with the USC. As of December 31, 2017, our USC was servicing Standard Commercial Lines NPW of $51.5 million and Standard Personal Lines NPW of $28.3 million. The $79.8 million total serviced by the USC represents 3% of our total NPW.

As mentioned above, our field model also provides a wide range of front-lineStandard Commercial Lines customer-focused safety management services focused on improving a Standard Commercial Lines insured’s safety and risk management programs.

By understanding our customers' exposures and recommending safety enhancements to reduce the risk from those exposures, our safety management specialists help us make better new and renewal underwriting decisions, while helping customers improve the safety of their operations.

To further our safety management efforts, over the past two years we have embarked on initiatives to proactively service policyholders with notifications and alerts, risk identification and mitigation of potential loss occurrence, and tools and technologies that can reduce losses and improve safety. Examples include:

Vehicle recall notifications to our policyholders and distribution partners;
Weather preparation notices for large storms or hurricanes, including guides on structural improvements, roof and drainage maintenance, and measures to prevent plumbing from freezing or clogging; and
14



Food and product recall notifications to policyholders in food manufacturing, distribution, or preparation.

Standard Personal Lines: Our Standard Personal Lines underwriting operations are centralized and highly automated. The majority of our new and renewal business is underwritten and priced through an automated system reflecting our filed rates and rules. Exceptions are approved under the direction of our Standard Personal Lines CUO. For long-term growth in this segment, we are actively repositioning our Standard Personal Lines business to workprovide our insurance products to a customer base that is less price sensitive, and more focused on insurance product coverage and service.

As of December 31, 2020, our USC was servicing NPW of $85.5 million, which represents 3% of our total NPW.


Claims Management
Effective, fair,Timely and timely claims managementappropriate investigation of a claim's facts and circumstances in light of our policy's terms, conditions, and exclusions is one of the most important services that we provide to our customerspolicyholders, their claimants, and our distribution partners. It also is also one of the critical factors in achieving underwriting profitability. WeIn the fourth quarter of 2020, we restructured our claims management process to more effectively administer claims. To address the increasing complexity of coverage evaluation, construction methods, and litigation, we have structured our claims organization to emphasize: (i) cost-effective

Claims handling by technical areas of expertise, such as auto liability, general liability, property, and workers compensation;
Claims customer managers and agency executives ("CAEs") who have responsibility for enhancing the relationship among our policyholders, agents, and our claims operation. The CAEs provide a single point-of-contact for our large account customers and distribution partners. They work with our regional underwriters to ensure appropriate claims service delivery, communicate trends, and discuss results and client services;
Cost-effective delivery of claims services and control of loss and loss expense; and (ii) maintenance of timely

We deploy specialized claims handling as follows:

Liability claims with high severity or technically complex losses are handled by the Complex Claims and Litigation Unit ("CCU"). The CCU specialists handle losses based on injury type or with expected severities greater than $250,000 in our Standard Commercial Lines and Standard Personal Lines.

Litigated matters not meeting the CCU criteria are handled within our litigation unit, where regional litigation managers supervise teams of litigation adjusters aligned by jurisdiction and technical experience.

E&S claims are handled by a dedicated group with specific expertise in E&S coverages, which differ from and often provide more limited coverages than Standard Lines we achieve better claim outcomes throughofferings.

Certain complex claims that do not involve structural damage (e.g. employee dishonesty and equipment breakdown losses) are handled by a small group of specialists in the CSC. The CSC has adopted the use of virtual claims handling tools in order to quickly assess the value of smaller claims and pay them in a timely and appropriate manner.

The Large Loss Unit ("LLU") handles complex property claims, typically those greater than $100,000.

Complex and litigated claims oversight is handled by specialists within the Complex Claims and Litigation Unit ("CCU").

We have implemented specialized claims handling as follows:

Liability claims with high severity or technically complex losses are handled by the CCU. The CCU specialists are primarily field based and handle losses based on injury type or with severities greater than $250,000.

Litigated matters not meeting the CCU criteria are handled within our regional litigation offices. These teams are aligned based upon jurisdictional knowledge and technical experience and are supervised by regional litigation managers. These claims are segregated from the CMSs to allow for focused management and application of specific technical expertise.

Workers compensation claims handling is centralized in Charlotte, North Carolina. Jurisdictionally trained and aligned medical-only and lost-time adjusters manage non-complex workers compensation claims within our footprint. Claims with high exposure and/or significant escalation risk are referred to the workers compensation strategic case management unit.

Insurance RegulationInvestments Segment
Primary Oversight by the States in Which We Operate
Our insurance operations are heavily regulated. The primary public policy behind insurance regulation isInvestments segment seeks to generate net investment income by investing the protection of policyholders and claimants over all other constituencies, including shareholders. By virtue of the McCarran-Ferguson Act, Congress has largely delegated insurance regulation to the various states. The primary market conduct and financial regulators of our Insurance Subsidiaries are the departments of insurance in the states in which they are organized and are licensed. The types of activities that are regulated by the states include:
Pricing and underwriting practices;
Claims practices;
Exiting geographic markets and/or canceling or non-renewing policies;
Assessments for guaranty funds and second-injury funds and other mandatory assigned risks and reinsurance;
The types, quality and concentration of investmentspremiums we make; and
Dividends from our Insurance Subsidiaries to the Parent.

For additional discussion of the broad regulatory, administrative, and supervisory powers of the various departments of insurance, refer to the risk factor that discusses regulation in Item 1A. “Risk Factors.” of this Form 10-K.

Our various state insurance regulators are members of the National Association of Insurance Commissioners ("NAIC"). The NAIC has codified statutory accounting principles ("SAP") and other accounting reporting formats and drafts model insurance laws and regulations governing insurance companies. An NAIC model only becomes law when it is enacted in the various state


legislatures or promulgated as a regulation by the state insurance department. The adoption of certain NAIC model laws and regulations, however, is a key aspect of the NAIC Financial Regulations Standards and Accreditation Program.

NAIC Monitoring Tools
Among the NAIC's various financial monitoring tools that are material to the regulators in states in which our Insurance Subsidiaries are organized are the following:

The Insurance Regulatory Information System (“IRIS”). IRIS identifies 13 industry financial ratios and specifies “usual values” for each ratio. Departure from the usual values on four or more of the financial ratios can lead to inquiries from individual state insurance departments about certain aspects of the insurer's business. Our Insurance Subsidiaries have consistently met the majority of the IRIS ratio tests.

Risk-Based Capital. Risk-based capital is measured by four major areas of risk to which property and casualty insurers are exposed: (i) asset risk; (ii) credit risk; (iii) underwriting risk; and (iv) off-balance sheet risk. Insurers face a steadily increasing amount of regulatory scrutiny and potential intervention as their total adjusted capital declines below two times their "Authorized Control Level". Based on our 2017 statutory financial statements, which have been prepared in accordance with SAP, the total adjusted capital for each of our Insurance Subsidiaries substantially exceeded two times their Authorized Control Level.

Annual Financial Reporting Regulation (referred to as the "Model Audit Rule"). The Model Audit Rule, which is modeled closely on the Sarbanes-Oxley Act of 2002, as amended ("Sarbanes-Oxley Act"), regulates: (i) auditor independence; (ii) corporate governance; and (iii) internal control over financial reporting. As permitted under the Model Audit Rule, the Audit Committee of the Board of Directors (the “Board”) of the Parent also serves as the audit committee of each of our Insurance Subsidiaries.

Own Risk and Solvency Assessment ("ORSA"). ORSA requires insurers to maintain a framework for identifying, assessing, monitoring, managing, and reporting on the “material and relevant risks” associated with the insurers' (or insurance groups') current and future business plans. ORSA, which has been adopted by the state insurance regulators of our Insurance Subsidiaries, requires companies to file an internal assessment of their solvency with insurance regulators annually. Although no specific capital adequacy standard is currently articulated in ORSA, it is possible that such standard will be developed over time and may increase insurers' minimum capital requirements, which could adversely impact our growth and return on equity.    

In addition to the formal regulation above, we are subject to capital adequacy monitoring by rating agencies, for example, Best's Capital Adequacy Ratio ("BCAR"). BCAR, which was developed by A.M. Best, examines an insurer's leverage, underwriting activities, and financial performance.

Federal Regulation
Notable federal legislation and administrative policies that affect the insurance industry are:
The Terrorism Risk Insurance Program Reauthorization Act ("TRIPRA");
The Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”); and
Various privacy laws that apply to us because we have personal non-public information, including the:
Gramm-Leach-Bliley Act;
Fair Credit Reporting Act;
Drivers Privacy Protection Act; and
Health Insurance Portability and Accountability Act.

Like all businesses, we are required to enforce the economic and trade sanctions of the Office of Foreign Assets Control (“OFAC”).

The Mitigation Division of the Federal Emergency Management Agency ("FEMA") oversees the WYO Program of the NFIP, which was enacted by Congress. Under the program, we receive an expense allowance for flood policies written and a servicing fee for flood claims administered, and all losses are 100% reinsured by the Federal Government.  Congress sets the WYO Program's budgeting, rules, and rating parameters.  Two significant pieces of legislation that impact the WYO Program are the Biggert-Waters Flood Insurance Reform Act of 2012 ("Biggert-Waters Act") and the Homeowner Flood Insurance Affordability Act of 2014 ("Flood Affordability Act"). The Biggert-Waters Act: (i) extended the NFIP funding to September 30, 2017; and (ii) moved the program to more market based rates for certain flood policies. The Flood Affordability Act repealed and modified certain provisions in the Biggert-Waters Act regarding premium adjustments.  The NFIP has received multiple short-term extensions and currently expires on March 23, 2018.



In response to the financial markets crises in 2008 and 2009, the Dodd-Frank Act was enacted in 2010. This law provided for, among other things, the following:

The establishment of the Federal Insurance Office (“FIO”) under the United States Department of the Treasury;
Federal Reserve oversight of financial services firms designated as systemically important; and
Corporate governance reforms for publicly traded companies.

The FIO, the Federal Reserve, state regulators, and other regulatory bodies have been developing models for capital standards, negotiated a covered agreement with the European Union that, among other things, impacted reinsurance collateral, and have been gathering data as required under the Dodd-Frank Act. Changes to the Dodd-Frank Act and FIO are expected as the Trump Administration and the Republican Congress seek opportunities to pare down the Dodd-Frank Act and its regulations. Legislation has passed the House that would limit the scope of the Dodd-Frank Act but has yet to be considered by the Senate. The Trump Administration, though, continues to seek regulatory limitations. For additional information on the potential impact of the Dodd-Frank Act, refer to the risk factor related to this legislation within Item 1A. “Risk Factors.” of this Form 10-K.

International Regulation
We believe that development of global capital standards will influence the development of similar standards by domestic regulators. Notable international developments include the following:

In 2014, the International Association of Insurance Supervisors proposed Basic Capital Standards for Global Systemically Important Insurers as well as a uniform capital framework for internationally active insurers; and

The European Union enacted Solvency II, which sets out new requirements on capital adequacy and risk management for insurers operating in Europe, which was implemented in 2016.

For additional information on the potential impact of international regulation on our business, refer to the risk factor related to regulation within Item 1A. “Risk Factors.” of this Form 10-K.

Investment Segment
Our Investment segment invests the cash we collect from our insurance policies prior tooperations and the payment of claims, as well as amounts generated through our capital management strategies, which may include the issuance of debt and equity securities. Our investment portfolio mainly consists of fixed income securities, to generate investment incomewhich primarily includes corporate securities, asset-backed securities, mortgage-backed securities, and to satisfy obligations to our customers, our shareholders,state and our debt holders, among others. Atlocal municipal obligations. As of December 31, 2017,2020, 13% of this portfolio was invested in floating rate securities that reset principally on the 90-day U.S. dollar-denominated London Interbank Offered Rate ("LIBOR"). We also hold both public and private equity securities, commercial mortgage loans, short-term investments, and other investments. Other investments primarily includes alternative investments.

To execute on this revised approach, we hired several new investment managers who were on-boarded in the fourth quarter of 2016. Since then, through active security selection, we have increased the book yield of our fixed income portfolio, which resulted in a higher level of net investment income in 2017, while maintaining the overall credit qualitypolicies and duration of the portfolio. In addition, we have continued to diversifyguidelines, financial planning, capital structure and have modestly increased our exposure to risk assets to 8% while moving towards a long-term target risk allocation of approximately 10% of total invested assets.

Regulation

Primary Oversight by the States in Which We Operate
Insurance is regulated, primarily at the state level, because of the McCarran-Ferguson Act. The primary public policy behind insurance regulation is protecting policyholders and claimants over all other constituencies, including shareholders. Insurance activities regulated by the states include the following:

Our ability to meet financial requirements to be able to pay claimants: Oversight of matters such as: minimum capital; surplus; solvency standards; accounting methods; form and content of statutory financial statements and other reports; loss and loss expense reserves; investments; reinsurance; dividend payments and other distributions to shareholders; security deposits; and periodic financial examinations.

Protection of policyholders: Related to our property and casualty insurance business, oversight of matters such as: certificates of authority and other insurance company licenses; licensing and compensation of distribution partners; premium rates (required to not be excessive, inadequate, or unfairly discriminatory); policy forms; policy terminations; claims handling and related practices; cybersecurity; data protection and customer privacy; reporting of premium and loss statistical information; periodic market conduct examinations; unfair trade practices; mandatory participation in shared market mechanisms, such as assigned risk pools and reinsurance pools; mandatory participation in state guaranty funds; and mandated continuing workers compensation coverage post-termination of employment.

Protection of policyholders, claimants, and shareholders: Related to our ownership of the Insurance Subsidiaries, oversight of matters such as: registration of insurance holding company systems in states where we have domiciled insurance subsidiaries, reporting about intra-holding company system developments, and required pre-approval of certain transactions that may materially affect the operations, management, or financial condition of the insurers, including dividends and change in control.

NAIC Financial Monitoring Tools
Our various state insurance regulators are members of the National Association of Insurance Commissioners ("NAIC"). The NAIC has established statutory accounting principles ("SAP") and other accounting reporting formats and model insurance laws and regulations governing insurance companies. The adoption of certain NAIC model laws and regulations is a key aspect of the NAIC Financial Regulations Standards and Accreditation Program, under which state insurance departments recognize the financial examinations and reviews done by other state insurance departments, which benefits insurance companies operating in multiple states by avoiding overlapping examinations. However, an NAIC model statute only becomes a law after a state legislature enacts it, and an NAIC model rule only becomes a regulation after a state insurance department promulgates it.

The following are among the NAIC's various financial monitoring tools, most predicated on NAIC model laws and regulations that are material to the regulators in states in which our Insurance Subsidiaries are organized:

The Insurance Regulatory Information System ("IRIS"). IRIS identifies 13 industry financial ratios and specifies “usual values” for each ratio. Departure from the usual values on four or more of the financial ratios can lead to inquiries from individual state insurance departments about certain aspects of an insurer's business. Our Insurance Subsidiaries have consistently met the majority of the IRIS ratio tests.

Risk-Based Capital ("RBC"). RBC is measured by four major areas of risk to which property and casualty insurers are exposed: (i) asset risk; (ii) credit risk; (iii) underwriting risk; and (iv) off-balance sheet risk. Regulators increase their scrutiny, up to and including intervention, as an insurer's total adjusted capital declines below three times its "Authorized Control Level." Based on our 2020 statutory financial statements prepared in accordance with SAP, the total adjusted capital for each of our Insurance Subsidiaries substantially exceeded three times their Authorized Control Level.

Annual Financial Reporting Regulation (referred to as the "Model Audit Rule"). The Model Audit Rule, based closely on the Sarbanes-Oxley Act of 2002, as amended ("Sarbanes-Oxley Act"), regulates (i) auditor independence, (ii) corporate governance, and (iii) internal control over financial reporting. As permitted under the Model Audit Rule, the
17



Audit Committee of the Board of the Parent can also serve as the audit committee of each of our Insurance Subsidiaries, even if the Parent is not an insurance entity.

Own Risk and Solvency Assessment ("ORSA"). ORSA requires an insurer to maintain a framework for identifying, assessing, monitoring, managing, and reporting on the “material and relevant risks” associated with the insurers' (or insurance groups') current and future business plans. ORSA, which the state insurance regulators of our Insurance Subsidiaries have adopted, requires an insurer to annually file an internal assessment of its solvency. For more information on our internal process of assessing our major risks, refer to the "Enterprise Risk Management" section below.

NRSROs
Rating agencies, although not formal regulators, also monitor our capital adequacy. Two are (i) AM Best Company, with its Capital Adequacy Ratio ("BCAR"), and (ii) S&P, with its capital model. Both examine the strength of an insurer's balance sheet and compare available capital to estimated required capital at various probability or rating levels. BCAR and the S&P model differ from the NAIC financial monitoring tools, particularly RBC. While RBC, BCAR, and the S&P capital model all show similar direction as circumstances change, they react differently to changes in economic conditions, underwriting and investment portfolio mix, and capital. Rating agencies also update and change their capital adequacy models and requirements more frequently than the NAIC does its financial monitoring tools. We analyze this divergence in capital adequacy models as we manage our capital, risk profile, and growth objectives.

Federal Regulation
While primarily regulated at the state level, our business is subject to certain federal laws and regulations, including:

The McCarran-Ferguson Act;
The Terrorism Risk Insurance Program Reauthorization Act ("TRIPRA");
The NFIP, which is overseen by the Mitigation Division of the Federal Emergency Management Agency ("FEMA");
The Medicare, Medicaid, and SCHIP Extension Act of 2007, which subjects our workers compensation business to Mandatory Medicare Secondary Payer Reporting;
The economic and trade sanctions of the Office of Foreign Assets Control (“OFAC”);
Various privacy laws related to possession of personal non-public information, including the following:
Gramm-Leach-Bliley Act;
Fair Credit Reporting Act;
Drivers Privacy Protection Act; and
Health Insurance Portability and Accountability Act.
The Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”), which govern, among other things, publicly-traded companies and require or permit national stock exchanges or associations, such as the Nasdaq Stock Market LLC, where our securities are listed, to mandate certain governance practices of their listed companies.

The Dodd-Frank Act, enacted in 2010 in response to the 2008 and 2009 financial markets crises, provided for some public company corporate governance reforms and some oversight of the business of insurance, including:

Establishing the Federal Insurance Office (“FIO”) under the U.S. Department of the Treasury; and
Granting the Federal Reserve oversight of financial services firms designated as systemically important.

The FIO, consistent with its Dodd-Frank Act (i) negotiated a covered agreement with the European Union that, among other things, impacted reinsurance collateral requirements for foreign reinsurers, and (ii) has been gathering insurance market data.
For additional information on the potential impact of regulation and changes in regulation on our business, refer to the risk factor related to regulation within Item 1A. “Risk Factors.” of this Form 10-K.

Enterprise Risk Management

As a property and casualty holding company, our Insurance Subsidiaries are in the business of assumingtaking risk. We categorize our major risks into the following fivesix broad categories:

Asset risk, which stems primarily from our investment portfolio and reinsurance recoverables and includes credit and market risk;
18



Underwriting risk, which is the risk that theour insured losses are higher thanexceed our expectations, including lossesincluding:
Losses from inadequate loss reserves, largerreserves;
Larger than expected non-catastrophe current accident year losses; and
Catastrophe losses and catastrophe losses;that exceed our expectations or our reinsurance treaty limits.
Liquidity risk, which is the risk we will be unable to meet contractual obligations as they become due because we are unable to liquidate assets or obtain adequate funding without incurring unacceptable losses;investment losses or borrowing expense;
EmergingPension risk, which is the risk that our obligations under the Retirement Income Plan for Selective Insurance Company of America exceed our expectations because the invested assets supporting those obligations underperform or there are adverse changes in the assumptions we used to calculate the pension liabilities;
Other risks, which are new and known but evolving risks that may have a significant impact on our financial strength, reputation, or long-term strategy; and
Other risks, includinginclude a broad range of operational risks, that can bemany difficult to quantify, such as talent/human capital, market conditions, economic, legal, regulatory, reputational, and strategic risks - as well as the riskrisks of fraud, human failure, andmodeling risks, inadequate business continuity plans, or failure of controls or systems, including, rapidly-evolving cybersecurity risk; and
Emerging risks, which include risks in each of the other five categories, but are new, rapidly evolving, or increasing substantially compared to historical levels. For example, we consider the increased frequency and systems.intensity of severe wildfires, the exposures created by the legalization of cannabis, the recent passage of reviver statutes for victims of abuse, the various potential impacts from climate change, and the significant economic and societal impacts from the COVID-19 pandemic, all to be emerging risks.


Our internal control framework operates with the three linesdeploys three-lines of defense model. defense:

The first line of defense consists ofare the individual business functions that deliberately assume, risks and own, and manage ourthe risk on a day-to-day and businessdaily operational basis.

A dedicated risk team led by theOur Chief Risk Officer, is responsible for this second line andwho reports to the Chief Financial Officer. Officer, leads a dedicated risk team responsible for this second line.
The third line of defense is our Internal Audit team whichthat, with oversight from our Board's audit committee, provides independent, objective assurance as to the assessment of the adequacy and effectiveness of our internal control environment. ItInternal Audit also coordinates risk-based audits, and compliance reviews, and other specific initiatives to evaluate and address risk within targeted areas of our business.


We use Enterprise Risk Management (“ERM”) as part of our governance and control process to take an entity-wide view of our major risks and their potential impact. OurWe designed our ERM framework is designed to identify, measure, report, and monitor our major risks and develop appropriate responses to support successful execution of our business strategy.strategies.

Our Board oversees our enterprise risk managementERM process, and sets our overall risk appetite, while the Executive Risk Committee is responsible for the holistic evaluation and supervision of our aggregated risk profile and determination of future risk management actions in support of overall risk appetite.  In addition to the Board’s oversight of the overall risk and the ERM process, various Board committees of the Board oversee risks specific to their areas of supervision and report their activities and findings to the full Board. TheManagement has formed an Executive Risk Committee uses various management committees("ERC") that is responsible for detailed analysisthe holistic monitoring and management of specific major risks.our risk profile. The Executive Risk Committee primarilyERC consists of the Chief Executive Officer, his direct reports and key operational and financial leaders, each of whom is responsible for management of risk in his or her respective area, andincluding the Chief Risk Officer.

The Chief Risk Officer reports on the ERC's activities, analyses, and findings to the various committeesBoard or the appropriate Board committee, and the governance process over ERM, we believe that high-quality andprovides a quarterly update on certain risk metrics.

High-quality, effective ERM is best achieved when it isas a shared organizational cultural value throughout the organization.

Consistent with the requirements of state insurance regulators,When appropriate, we engage subject matter experts, such as external actuaries, third-party risk modeling firms, and IT and cybersecurity consultants. Annually, our Insurance Subsidiaries annually file their ORSA report, an internal solvency assessment developed by the Chief Risk Officer in coordination with the ERC, with their domiciliary regulator after review by our Board.

19



COVID-19 has been a significant emerging risk and a focus of the ERC in 2020, and will continue to remain a focus into 2021. To monitor and manage COVID-19-related developments, our ERC met daily in March, multiple times a week through April, transitioned to weekly meetings in May, June, and July, and since has met monthly. The ERC continues to actively review and address all significant operational, compliance, and financial risk matters related to COVID-19. This oversight includes matters such as employee health and safety, facilities matters, operational business continuity, IT including third-party vendors, regulatory developments, premium collections, past due accounts, investments, liquidity, capital, cash flow, claims activity, and other key business metrics. Our Management Investment Committee, which has oversight of our investment portfolio, also met weekly in the early days of the COVID-19-related financial market disruption, transitioned to meeting every two weeks, and now meets monthly. This committee has carefully reviewed detailed portfolio metrics and market projections and, during the crisis, has communicated and met regularly with our portfolio managers, allowing it to make proactive investment decisions on an informed basis. Our Board met weekly with senior executives through April, transitioned to bi-weekly meetings in May, June, and July, and since has met monthly to ensure appropriate corporate governance and oversight.

We have not had to modify our existing internal controls or processes in any significant way in response to the pandemic and we have not experienced any material impact to our internal control environment over financial reporting despite having the majority of our employees working remotely in response to the pandemic. We are continually monitoring and assessing COVID-19-related current events to minimize their potential impact on our internal controls and their design and operating effectiveness.

Given the COVID-19-related governmental actions and directives, remote access to critical systems is required. For several years, our IT security strategy has emphasized endpoint controls for cloud computing and employee mobility. This strategy leveraged a virtual private network with multi-factor authentication that is supplemented by a virtual desktop infrastructure, where necessary or appropriate, to create a highly-available and centrally-managed end-user environment. The technology supporting this strategy was already in use by our 675 home-based employees, as well as anyone working remotely on an ad hoc basis. As a result, our cybersecurity program was well-positioned to support increased remote working arrangements and respond to an increase in attempted attacks to exploit the COVID-19 outbreak without rolling back controls. Our cybersecurity strategy also has always included an information security education and awareness program that combines training with testing aligned to key security exposures, including phishing and social engineering, which is an internal assessment ofongoing challenge for our Insurance Subsidiaries' solvency.employees and vendors. We recently strengthened our phishing risk management by deploying multiple technology-driven controls that include malicious content checks, malicious link blocking, and reputation-based rules.

It also promotes robust risk management practices.practices, which served us well in 2020 as we evaluated and managed the emerging risk of COVID-19. All of our strategies and controls, however, have inherent limitations. We cannot be certain that an event or series of unanticipated events will not occur and result ingenerate losses greater than we expect and have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

Risks Related to COVID-19

Governmental actions to contain or delay the spread of the COVID-19 pandemic since early March 2020 have disrupted ordinary business commerce and impacted financial markets. These governmental actions, for which we cannot predict the extent, duration, and possible alteration based on future COVID-19-related developments, could materially and adversely affect our results of operations, financial position, and liquidity.
These actions generally have:

Negatively impacted the global and United States domestic economies, with some sectors such as travel and leisure, retail, energy, and real estate more significantly affected than others;
Increased unemployment;
Increased international, federal, state, and local government budget deficits, which has led to adverse rating actions against certain governmental units and increased the general risk of government debt default that could impact the value of related fixed income securities;
Induced significant volatility in financial markets;
Decreased valuations in markets for equity, fixed income, and alternative investments in certain sectors;
Impacted individual income and business revenue, and increased the number of individuals and businesses experiencing financial distress with the potential for insolvency;
Decreased premium collections, late payment fees, and reinstatement fees;
Generated state and federal legislative or executive branch proposals to (i) require insurance policies to retroactively cover COVID-19-related losses expressly excluded under the terms of some property insurance policies, and (ii) presume that COVID-19 is a work-related illness for certain employees under workers compensation policies;
Generated state insurance department bulletins or orders requesting or mandating premium credits and rebates on certain insurance policies that may exceed actual COVID-19-related frequency experience decreases;
Disrupted commerce, supply chains, and travel to varying degrees;
Increased expense management focus by individuals and all-sized businesses;
Increased the demand for and/or limited the availability of certain types of medical resources; and
Increased e-commerce, video, phone, and other methods of remote trade and business transaction.

The economic impacts of the COVID-19-related governmental actions may impact our revenue, loss and loss expense, liquidity, or regulatory capital and surplus, and operations, particularly as these relate, without limitation, to the following:

Impact on Our Insurance Operations

Because our general liability and workers compensation policies provide for premium audit to assure pricing for actual risk exposure, we must estimate return premium that we may owe policyholders for revenues and payrolls lowered by the extent and duration of the COVID-19-related governmental directives and related economic contraction. Such return premiums could be significant and will impact our underwriting results. Our results include the impact of a $75 million return audit and mid-term endorsement premium accrual recorded in the first quarter of 2020, which reflects our estimate of reduced exposures on the in-force workers compensation and general liability portfolio as of March 31, 2020. As of December 31, 2020, we had a remaining accrual of $24.8 million.

In the second quarter of 2020, we offered a credit equal to 15% of insureds’ premiums for our standard lines commercial automobile and personal automobile lines of insurance for April and May totaling $19.7 million. This two-month premium credit was based on a limited amount of claims reporting data reflecting the impact of the COVID-19-related governmental directives on miles driven, which has reduced claims frequencies. Due to the sudden and dynamic nature of these impacts, we did not rely upon traditional actuarial analysis to support these credits. We will not know the actual impact of the COVID-19-related governmental actions until some point in the future. Should the various governmental directives be extended or reinstated due to increased infection rates, we may give further premium credit to our customers to the extent supported by further analysis. Based on the continued COVID-19-related economic impact, state insurance commissioners may take other regulatory actions requiring additional premium credits in commercial and personal automobile and other lines, and we face the risk that we may be required to return more premium than is warranted by our filed rating plans and actual loss experience.

All of our commercial property and businessowners' policies require direct physical loss of or damage to property by a covered cause of loss to trigger a business interruption claim. Whether COVID-19-related contamination, the existence of a pandemic, and/or the resulting government shutdown orders cause physical loss of or damage to property continues to be the subject of much debate and litigation. We cannot predict the outcome of that litigation. Our practice is to include in, or attach to, all standard lines commercial property and businessowners' policies an
21



exclusion that states that all loss or property damage caused by or resulting from any virus, bacterium, or other microorganism that induces or is capable of inducing physical distress, illness, or disease is not a covered cause of loss. We offer some limited coverages that could apply in COVID-19-related claims and circumstances, primarily tied to clean-up and food-contamination that are subject to sub-limits. Approximately 95% of our commercial property and businessowners' policies include the very specific and regulatory approved virus exclusion.

We purchase a significant amount of reinsurance, including a property catastrophe reinsurance program and property and casualty excess of loss reinsurance treaties. In response to the COVID-19 pandemic and recent increased catastrophic loss activity, the reinsurance industry is seeking to tighten contractual terms and conditions, reduce reinsurance capacity, and increase its pricing for reinsurance protection. Tightened terms and conditions include introducing new coverage exclusions, such as excluding losses related to communicable diseases, particularly for business interruption losses in property treaties and, to a lesser extent, in casualty treaties. To the extent we are exposed to losses on our primary policies from risks, such as communicable disease, these losses will most likely be excluded from coverage under our new reinsurance treaties, and we now face increased underwriting risk. This increased underwriting risk could increase our net loss and loss expenses and increase the volatility in our underwriting results. We experienced risk-adjusted reinsurance price increases at our January 1, 2021 renewals that were at rates higher than we are likely able to generate on the underlying insurance policies we sell.

In response to the COVID-19 pandemic, there currently are various public policy debates and legislative and regulatory proposals at both the federal and state levels:
Certain states have proposed legislation that would impose liability (including retroactively) for COVID-19-related business interruption losses on policies that do not provide such coverage terms. We cannot predict the outcome of such proposals. We believe that if any of these proposals were enacted, they could impair future commercial activity and would likely be determined unconstitutional after being challenged through litigation. Nonetheless, if such proposals were enacted and upheld as constitutional, they could have a material impact on our profitability, liquidity, and overall financial condition and results of operations.

We are aware of four future pandemic insurance proposals being discussed in Washington, D.C., only one of which has been introduced as proposed legislation. Three of the proposals provide for insurer participation and put insurer capital at risk to various degrees. If any of the proposals involving insurer at risk capital were enacted, it could have a material impact on our profitability, liquidity, and overall financial condition and results of operations.

Certain state insurance departments have indicated that they currently (i) will not approve the filing of rate increases or decreases related – or unrelated – to COVID-19, and (ii) are suspending, limiting, or restricting the approval or attachment of new virus-related exclusions. To the extent any of these regulatory actions do not permit us to modify our rating plans, they could have a material impact on our profitability, liquidity, and overall financial condition and results of operations.

Limited medical resources availability could result in medical inflation and complicate, delay and/or extend medical treatment that could impact exposure on workers compensation, general liability, and personal and commercial automobile claims.

Economic inflation could increase our loss and loss expense reserves, particularly associated with our longer tail lines of business.

We may have increased workers compensation loss and loss expenses if policyholders' employees in high-risk roles of essential businesses contracted COVID-19 in the workplace. We may experience higher frequency of workers compensation claims, particularly as state legislative or executive order proposals are enacted that create presumptions that the contraction of COVID-19 by an essential business employee who interacted with the public is work-related. We also may see an extension of workers compensation benefits if employees do not have jobs to which they can return.

We may experience an increase in liability claims against our policyholders related to business practices as remote-office work-from-home employees return to their pre-COVD-19 office and business locations. This may be exacerbated by an active plaintiffs’ bar seeking to generate COVID-19-related claim activity.

Loss frequency and severity could increase related to our auto and property coverages due to, among other things,
22



disruptions in supply chains and changes in business practices and individual behaviors resulting from the shelter-in-place and social distancing measures, such as arson and fraud.

Due to the COVID-19-related governmental orders, we may experience delayed reporting of losses, settlement negotiations, and trial of disputed claims that may disrupt our normal claims resolution processes and trends.

Service levels could deteriorate if significant numbers of our (i) employees were to be simultaneously infected by COVID-19, whether working remotely or in one of our offices, and/or (ii) remote employees or key business partners are unable to work effectively while sheltering-in-place. Examples of potential work impacts include local internet disruption that prevents access to our virtual private network or similar unavoidable events. Because our employees are working remotely, it also is possible that we will be subject to increased cybersecurity attacks from bad actors.

Impact on our Investment Operations

The COVID-19 pandemic and the related governmental orders may result in further significant equity and debt market volatility that could impact our net investment income due to the following:

Financial market volatility is reflected in our alternative investment portfolio performance;

A change in spreads on fixed income securities may create mark-to-market investment valuation losses and volatility in unrealized capital gains, which will impact GAAP equity;

Losses on securities that we intend to sell may increase, as we give our third-party investment managers flexibility to take advantage of the spread widening in fixed income securities, particularly in asset classes more significantly impacted by COVID-19-related governmental directives and to which the Federal Reserve Board is providing liquidity and structural support;

Economic inflation related to COVID-19 issues could be higher or lower than our expectations and impact our investment returns; and

A potential increase in credit risk associated with municipal bonds for which repayment is supported by dedicated revenue streams that may be impacted by COVID-19.

Impact on our Capital Position, Liquidity and Financial Leverage

Out of an abundance of caution, we significantly increased our short-term debt during the first quarter of 2020 to enhance our liquidity and provide us with additional financial flexibility due to the market volatility and economic uncertainty from the COVID-19 pandemic. These short-term borrowings totaled $302 million, and we invested the proceeds in high-quality money market funds and fixed income securities. In addition to the $302 million of short-term borrowings, our GAAP equity decreased from $2.2 billion at December 31, 2019 to $2.1 billion at March 31, 2020, driven by a reduction in net unrealized gains in our investment portfolio. The combination of the additional borrowings and lower GAAP equity resulted in an increase in our debt to total capitalization ratio from 20.1% at December 31, 2019 to 28.9% at March 31, 2020, above our longer term target of 25%.

We subsequently repaid these short-term borrowings by December 31, 2020.The reduction in the short-term borrowings, as well as an increase in our GAAP equity to $2.7 billion at December 31, 2020, inclusive of our issuance on December 2, 2020, of $200.0 million of 4.60% non-cumulative preferred stock ("Preferred Stock"), has decreased our debt to total capitalization ratio to 16.7% at December 31, 2020.

Despite the improvement in our capital position and a reduction in our debt to total capitalization since the first quarter of 2020, the ongoing COVID-19 pandemic, in future periods, could cause a reduction in our GAAP income or equity, decrease our liquidity, and result in an increase in our debt to total capitalization.This could impact our financial strength ratings and impair our business.

Risks Related to our Insurance Operations

We are subject to losses from catastrophic events.
Our results are subject to lossesLosses from natural and man-madehuman-made catastrophes including, but not limited to:without limitation, hurricanes, tornadoes, windstorms, earthquakes, hail, terrorism, including cyber-attacks, explosions, severe winter weather, derechos, floods, and fires, some of which may be related to climate changes.change - and terrorism, including cyber-attacks, civil unrest, and explosions, can negatively impact our financial results. The frequency and severity of these catastrophes are inherently unpredictable. One year may be relatively freeIn recent years, the global insurance industry has seen an escalation in the frequency and severity of such events while another may have multiple events. For further discussion regarding man-made catastrophes that relate to terrorism, see the risk factor directly below regarding the potential for significant losses from actscatastrophes.

The United Nation’s Intergovernmental Panel on Climate Change (“IPCC”) is an international body responsible for assessing climate change science. In 2018, the IPCC reported in its "Special Report on Global Warming of terrorism.
There is widespread interest among scientists, legislators, regulators,1.5°C" that human activities are estimated to have caused approximately 1.8°F of global warming above pre-industrial levels and that, if the trend continues at the current rate, it will reach 2.7°F above pre-industrial levels between 2030 and 2052. Climate change models project robust differences in global regional climate characteristics between 1.8°F and 3.6°F. These differences, whether attributable to human activities or natural, include increases in (i) mean temperature in most land and ocean regions, (ii) hot extremes in most inhabited regions, (iii) heavy precipitation in several regions, and (iv) the probability of drought and precipitation deficits in some regions. These differences and increases can impact weather patterns and the public regarding the effect that greenhouse gas emissions may have on our environment, including climate change. If greenhouse gasses continue to impact our climate, it is possible that more devastating catastrophic events could occur.

The magnitude of catastrophe losses is determined by thefrequency and severity of the eventcatastrophes including hurricanes, severe convective storms, and the total amount of insured exposures in the area affected by the event as determined by ISO's Property Claim Services unit. Most of the risks underwritten by ourwildfires. The IPCC's 2019 "Special Report on Climate Change and Land" reinforced these findings.

Our insurance operations are concentrated geographicallyprimarily write risks in the Eastern, Midwestern, and MidwesternSouthwestern regions of the country. In 2017, approximately 20% of NPW were related to insurance policies written in New Jersey. Catastrophes inU.S. Our most significant catastrophe exposures are (i) hurricanes impacting the Eastern U.S., (ii) terrorism events, (iii) severe convective storms, including hailstorms and Midwestern regions of the U.S.tornadoes, and (iv) winter storms. Single storms could adversely impact our financial results, but it is also possible that we could experience more than one severe catastrophic event in any given calendar year. We track our severe weather and catastrophe losses using definitions and information we obtain from ISO’s Property Claim Services unit, an internationally recognized expert on U.S. storm losses.

Certain factors can impact our estimates of ultimate costs for catastrophes, including:
i.Inability to access portions of the impacted areas following a catastrophic event;
ii.Scarcity of necessary labor and materials that delay repairs and increase our loss costs;
iii.Regulatory uncertainties, including new or expanded interpretations of coverage;
iv.Residual market assessment-related increases in our catastrophe losses;
v.Potential fraud and inflated repair costs, partly driven by (a) demand surge post-event, and (b) opportunistic service providers;
vi.Higher loss adjustment expenses due to shortages of claims adjusters available to appraise damage;
vii.Late claims reporting;
viii.Escalation of business interruption costs due to infrastructure disruption; and
ix.Whether the U.S. Secretary of Treasury certifies a terrorist event as wasan act of terrorism under TRIPRA.

An increase in catastrophe losses likely will reduce our net income and stockholders’ equity and could have a material adverse effect on our liquidity, financial strength, and debt ratings. The closer a catastrophe occurs to the caseend of a reporting period, the more likely it is we have limited information to estimate loss and loss expense reserves, adding greater uncertainty to our estimates. More detailed claims information available after the end of a reporting period may result in 2010, 2011,reserve changes in subsequent periods.

Our loss and 2012.loss expense reserves may not be adequate to cover actual losses and expenses.
We maintain reserves for our estimated liability for loss and loss expense associated with reported and unreported insurance claims. We base our loss and loss expense reserve estimates on known facts and circumstances, including our expectations of ultimate settlement and claim administration expenses, trends in claims severity and frequency, medical inflation trends, predictions of future events, and other subjective factors relating to our in-force insurance policies. There is no method for precisely estimating the ultimate liability for the settlement of claims.
Although catastrophes can cause losses in
Reserve estimates may be impacted by a variety of broad economic, political, social, and legal developments or trends, such as inflation, judicial tort decisions, and various state legislative initiatives. Because we cannot predict the timing and impact of these economic, political, social, and legal developments or trends, and estimating loss and loss expense reserves is inherently uncertain, we cannot be sure the reserves we establish are adequate or will be so in the future.

We review our reserve position quarterly and adjust the reserve position accordingly. An increase in reserves (i) reduces net income and stockholders’ equity, and (ii) could have a material adverse effect on our liquidity, financial strength, and debt

ratings. As we underwrite new business and renew existing business, we estimate future loss cost trends in pricing our products to generate an adequate risk-adjusted return. If our estimate of future loss cost trends proves to be understated, our pricing of future new and renewal business may be inadequate to meet estimated loss costs trends, understating our future loss and loss expense reserves.

The COVID-19 pandemic is an example of how loss and loss expense reserves might be affected by economic, political, social, or legal developments or trends. Two additional examples are:

If economic inflation, including medical inflation, is higher than our assumptions, our loss and loss expense reserves associated with our longer tail lines of business may prove to be insufficient. In particular, our workers compensation line of business is susceptible to this risk, given its extended payment pattern and the current low medical inflationary environment compared to long-term medical inflation rates, which have historically been higher.

Several states have expanded or are exploring expanding the statute of limitations for civil actions alleging sexual abuse. By retroactively permitting claims for previously time-barred acts, these “reviver” laws may result in insurance claims that could significantly increase loss costs and require re-evaluation of previously-established reserves or the creation of new reserves. Since reviver statutes have been enacted, we have received notices of claims or potential claims for acts alleged to have occurred as far back as the 1950s. Without prior experience, we cannot estimate how many "reviver" claims notices we may receive. Most notices we have received are sent on behalf of claimants by attorneys unsure of what insurer or policy (if any) may have covered the alleged assailant or supervising entity and may not implicate insurance policies issued by us or a predecessor. For notices we have determined implicate an insured under a policy issued by us or a predecessor, we (i) have investigated or are investigating facts, (ii) have evaluated policy terms, and (iii) believe we have appropriate coverage defenses and reinsurance protections that have been considered in establishing our reserves. As coverage positions may be challenged through litigation or otherwise, we face litigation risks further discussed below in the Risk Factor entitled, “Incidental to our insurance operations, we are engaged in ordinary routine legal proceedings that, because litigation outcomes are inherently unpredictable, could impact our reputation and/or have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods.”

For further discussion on our loss and loss expense reserves, please see the “Critical Accounting Policies and Estimates” section of Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” and Note 2. "Summary of Significant Accounting Policies" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

Our ability to reduce our risk exposure depends on the availability and cost of reinsurance.
We transfer a significant portion of our underwriting risk exposure - specifically a portion of our loss and loss expense - to reinsurance companies in exchange for a specified portion of premiums. Most of our reinsurance contracts have annual terms. The availability, amount, and cost of reinsurance depend on market conditions, including retrocessional reinsurance market capacity. This may fluctuate significantly and not necessarily correlate to the loss experience of our specific book of business. In general, we can consider catastrophe reinsurance expense in our filed rates and rating plans. Any other disproportionate increase in our reinsurance expense that we cannot include in our filed rates and rating plans will reduce our earnings. If we do not obtain expected reinsurance amounts or terms, our reinsurance expenses could increase, we may assume increased risk for individual or aggregate losses, and our ability to write future business could be adversely affected.

Catastrophes impact many property and casualty insurance lines, most of our historical catastrophe-related claims have been frombut commercial property and homeowners coverages. In an effort tocoverages historically have accounted for most of our catastrophe-related claims. To limit our exposure to catastrophe losses, we purchase catastrophe reinsurance. CatastropheIt is possible that our reinsurance coverage could provebe inadequate, particularly if: (i)

We do not purchase sufficient amounts of reinsurance because of defects or inaccuracies in the various modeling software programs that we use to analyze theour Insurance Subsidiaries’ risk result in an inadequate purchase of reinsurance by us; (ii) aSubsidiaries' risk;
A major catastrophe loss exceeds the purchased reinsurance limit or is within the reinsurers’limits, but exceeds the financial capacity;capacity of one or (iii) themore of our reinsurers;
The frequency of catastrophe losses results inincreases and our Insurance Subsidiaries' insured losses exceed the aggregate limits of the catastrophe reinsurance treaty or our Insurance Subsidiaries exceeding the aggregate limits provided by the catastropheexperience an aggregation of losses that fall below our per occurrence reinsurance treaty. Even after consideringretention; or
Our reinsurance counterparties (a) are unable to access their reinsurance markets, or retrocessions, (b) suffer significant financial losses, (c) are sold, (d) cease writing reinsurance business, or (e) are unable or unwilling to satisfy their contractual obligations to us.
25



Typically, our reinsurance protection,contracts align with our primary insurance policies. For example, if our primary insurance policies provide coverage for a loss, then our reinsurance contracts typically provide coverage as well (subject to any specific exclusions the reinsurance contracts may contain).

In response to the COVID-19 pandemic and recent increased catastrophic loss activity, the reinsurance industry has sought to tighten contractual terms and conditions, reduce reinsurance capacity, and increase pricing. Tightened terms and conditions include introducing new coverage exclusions, such as excluding losses related to cyber risk and communicable diseases, particularly for business interruption losses in property treaties and, to a lesser extent, in casualty treaties. To the extent we are exposed to losses on our primary policies from risks, such as cyber and communicable disease, that are now principally excluded from coverage under our reinsurance treaties, we face increased underwriting risk. The increased underwriting risk could increase our net loss and loss expenses and increase the volatility in our underwriting results. Decreased reinsurance capacity also would increase our underwriting risk if we cannot fully place our existing reinsurance treaties upon renewal. We experienced risk-adjusted reinsurance price increases at our January 1, 2021 renewals that were at rates higher than we are likely to generate on the underlying insurance policies we sell. This will negatively impact our underwriting profitability in 2021.

Even with the benefits of reinsurance, our exposure to catastrophe risks could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.
Our loss and loss expense reserves may not be adequate to cover actual losses and expenses.
We are required to maintain loss and loss expense reserves for our estimated liability for loss and loss expense associated with reported and unreported insurance claims. Our estimates of reserve amounts are based on facts and circumstances that we know, including our expectations of the ultimate settlement and claim administration expenses, trends in claims severity and frequency, including inflationary trends particularly regarding medical costs, predictions of future events, and other subjective factors relating to our insurance policies in force. There is no method for precisely estimating the ultimate liability for


settlement of claims. We cannotmay be certain that the reserves we establish are adequate or will be adequate in the future. From time-to-time, we increase reserves if they are inadequate or reduce them if they are redundant. An increase in reserves: (i) reduces net income and stockholders’ equity for the period in which the reserves are increased; and (ii) could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

We are subject to potentially significant losses from acts of terrorism.
As a Standard Commercial Lines and E&S Lines writer, weWe are required to participate in TRIPRA, which was extended by Congress to December 31, 2020.2027, for our Standard Commercial Lines and E&S Lines business. TRIPRA rescinded all previously-approved coverage exclusions for terrorism and requires private insurers and the U.S. government to share the risk of loss on future acts of terrorism certified by the U.S. Secretary of the Treasury. Under TRIPRA, insuredseach participating insurer is responsible for paying a significant deductible of specified losses before federal assistance is available. Our deductible of $369 million is based on a percentage of our prior year’s applicable Standard Commercial Lines and E&S Lines premiums. For losses above the deductible in 2021, the federal government will pay 80% of losses, and the insurer retains 20%. Although TRIPRA’s provisions provide some mitigation to our loss exposure to a large-scale terrorist attack, our deductible could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings. If the U.S. Secretary of Treasury does not certify certain future terrorist events, as happened with the 2013 Boston Marathon bombing and the 2015 San Bernardino shootings, we could be required to pay terrorism-related covered losses without TRIPRA's risk-sharing benefits. We also could be required to pay terrorism-related losses for customers who declined terrorism coverage.

Under TRIPRA, terrorism coverage is mandatory for all primary workers compensation policies. TRIPRA also applies to cyber liability insurance policies reported under a Terrorism Risk Insurance Program-eligible line of insurance. Insureds with non-workers compensation commercial policies have the option to accept or decline our terrorism coverage or negotiate with us for other terms. In 2017, 90%2020, 86% of our Standard Commercial Lines non-workers compensation policyholders purchased terrorism coverage that included nuclear, biological, chemical, and radioactive ("NBCR") events. Terrorism coverage is mandatory for all primary workers compensation policies, so the TRIPRA back-stop applies to these policies. A risk exists that, if the U.S. Secretary of Treasury does not certify certain future terrorist events, we would be required to pay related covered losses without TRIPRA's risk sharing benefits. Examples of this potential risk are the 2013 Boston Marathon bombing and the 2015 shootings in San Bernardino, California, neither of which were certified as terrorism events.

Under TRIPRA, each participating insurer is responsible for paying a deductible of specified losses before federal assistance is available. This deductible is based on a percentage of the prior year’s applicable Standard Commercial Lines and E&S Lines premiums. In 2018, our deductible is $323 million. For losses above the deductible, the federal government will pay 82% of losses to an industry limit of $100 billion, and the insurer retains 18%. The federal share of losses will be reduced by 1% each year to 80% by 2020. Although TRIPRA’s provisions will mitigate our loss exposure to a large-scale terrorist attack, our deductible is substantial and could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

TRIPRA rescinded all previously approved coverage exclusions for terrorism. Many of the states in which we write commercial property insurance mandate that we cover fire following an act of terrorism - regardless of whether the insured specifically purchasedopted to purchase terrorism coverage. Likewise,We also sometimes elect to provide terrorism coverage cannot be excluded from workers compensation policies in any state in which we write.

Personalfor lines of business havenot included in TRIPRA, such as Commercial Automobile. TRIPRA has never been covered under TRIPRA. Homeownerspersonal lines of business. Our homeowner policies within ourin Standard Personal Lines exclude nuclear losses, but they do not exclude biological or chemical losses. Our current reinsurance programs generally provide coverage for conventional acts of foreign and domestic terrorism, but afford no coverage for NBCR events.

Our ability to reduce our risk exposure depends on the availability and cost of reinsurance.
We transfer a portion of our underwriting risk exposure to reinsurance companies. Through our reinsurance arrangements, a specified portion of our loss and loss expense are assumed by the reinsurer in exchange for a specified portion of premiums. The availability, amount, and cost of reinsurance depend on market conditions, which may vary significantly. Most of our reinsurance contracts renew annually and may be impacted by the market conditions at the time of the renewal that are unrelated to our specific book of business or experience. Any decrease in the amount of our reinsurance will increase our risk of loss. Any increase in the cost of reinsurance that cannot be included in renewal price increases will reduce our earnings. Accordingly, we may be forced to incur additional expenses for reinsurance or may not be able to obtain sufficient reinsurance on acceptable terms. Either could adversely affect our ability to write future business or result in the assumption of more risk with respect to those policies we issue.
We are exposed to credit risk.
We are exposed toface credit risk in several areas of our insurance operations, including from:

Our reinsurers, whowhich are obligated to make payments to us under our reinsurance agreements. Amounts recoverable from our reinsurersReinsurance credit risk can increase quickly and significantlyfluctuate over time, increasing during periods of high industry catastrophe losses. Reinsurers generally manage their large loss activity, so our credit risk related to our reinsurance relationships can increase significantly and will fluctuate over time. In addition, our reinsurers often rely onexposure through their own reinsurance programs, or retrocessions, as part of managing their exposure to large losses. Givenabout which we do not always have the relatively small size of the global reinsurance community, the inability offull details. If our reinsurers to collecthave difficulty collecting on their retrocession program,programs or their inability to reinstate theirin reinstating retrocession coverage after a large loss, we may impair their ability to pay us for the amounts we cede to them. Accordingly,not receive timely or full payment of our reinsurance claims. This means that we have direct and indirect counterparty credit risk fromto our reinsurers. We attempt to mitigate this credit risk by: (i) pursuing relationships with reinsurers rated “A-” or higher by A.M.

Our exposure to credit risk could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.


Difficult conditionsWe depend on distribution partners.
We market and sell our insurance products through independent, non-employee distribution partners. Insurance law and regulation makes us responsible for the business practices and customer interactions of our distribution partners. Independent distribution partners have, and we expect will continue to have, a significant role in global capitaloverall insurance industry premium production. While our customers find advantages in using independent distribution partners, our reliance on independent distribution partners presents risks and challenges, including:

Competition in our distribution channel, as independent distribution partners have access to products from multiple carriers and markets, and we must market our products and services to our distribution partners before they sell them to our mutual customers.

Challenges in developing brand recognition that require us to closely coordinate with our distribution partners, as some customers cannot differentiate their insurance agent from their insurance carrier.

Our market share growth is tied to the economygrowth in market share controlled by our distribution partners. Independent retail insurance agencies control 85% of standard commercial lines business and 36% of standard personal lines business in the U.S. Consequently, expansion of our Standard Personal Lines market opportunity could be more limited than our Standard Commercial Lines business. More competitors have focused on lower-cost "direct-to-the-customer" distribution models that emphasize digital ease and technological efficiencies to address the discrepancy in agency control of Standard Personal Lines business. Continued advancements in "direct-to-the-customer" distribution models may impact the overall market share controlled by our independent distribution partners and make it more difficult for us to grow, or require us to establish relationships with more distribution partners.

Aggregation and consolidation of our independent distribution partners and their market share, as some publicly-traded and private equity-backed independent distribution partners have deployed consolidation strategies to acquire other independent distribution partners and increase their market share ("Aggregators") over the last decade. If more of our independent distribution partners become Aggregators, or are acquired by Aggregators, Aggregator demands and influence on our business could increase. For example, Aggregators could develop and implement strategies to consolidate their business with fewer insurers and demand higher base and supplemental commissions. Aggregators accounted for approximately 33% of our DPW at December 31, 2020, up from 20% three years ago. Currently, no one distribution partner is responsible for 10% or more of our combined insurance operations' premium.

Our financial condition and results of operations are impacted by our independent distribution partners' success in marketing and selling our products and services.

National and global economic conditions could adversely and materially affect our business, results of operations, financial condition, and growth.
Unfavorable economic developments, such as those that occurred during the COVID-19 pandemic, could adversely affect our revenueearnings if our policyholders need less insurance coverage, cancel existing insurance policies, modify coverage, or choose not to renew with us.

Unfavorable economic developments could adversely affect our earnings if our customers have less need for insurance coverage, cancel existing insurance policies, modify coverage, or choose not to renew with us. Challenging economic conditions may impair the ability of our customers to pay premiums as they come due. Adverse economic conditions may have a material effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

A downgrade or a potential downgrade in our financial strength or credit ratings could result in a loss of business and could have a material adverse effect on our financial condition and results of operations.

We have many competitors and potential competitors.
Demand for insurance is influenced by prevailing general economic conditions. The supplyface substantial competition from a wide range of insurance is related to prevailing prices, insured loss levels, and industry capital levels that may fluctuate in response to changing rates of return on insurance industry investments. Pricing also is influenced by the operating performance of insurers, who may increase pricing to meet return on equity objectives. As a result, the insurance industry has had historical cycles characterized by periods of intense price competition due to excessive underwriting capacity and periods of favorable pricing driven by shortages of capacity and poor insurer operating performance. If competitors price business below technical levels, we might find it necessary to reduce our profit margin to retain our best business.
Pricing and loss trends impact our profitability. For example, assuming retention and all other factors remain constant:

A pure price decline of approximately 1% would increase our combined ratio by approximately 0.75 points;
A 3% increase in our expected claim costs for the current accident year would cause our loss and loss expense ratio to increase by approximately 1.75 points;
A combination of the two could raise the combined ratio by approximately 2.5 points.
In addition, loss trends impacting current accident year results are likely to impact our reserves for prior accident years. For example, medical inflation can have a significant impact on the reserves of long-tail lines such as workers compensation and general liability. A 3% increase in our reserves would cause our loss and loss expense ratio to increase by approximately 4 points.

We compete with regional, national, and direct-writer property and casualty insurance companies for customers, distribution partners, and employees. Some competitors areCompetitors include public, companiesprivate, and some are mutual insurance companies. Many competitors are larger and may have lower operating costs, lower cost of capital, or the ability to absorb greater risk while maintaining their financial strength ratings. Other competitors, such as mutual or reciprocal companies, are owned by or operated cooperatively for insureds and, unlike us, do not have shareholders who evaluate return on equity performance. Consequently, some competitors may be able to price their products more competitively. These competitive pressures could result in increased pricing pressures on a number of our products and services, particularly as competitors seek to win market share, and may limit our ability to maintain or increase our profitability. Because of its relatively low cost of entry, the internet

The Internet has emerged as a significant place of new competition, both fromcompetitive marketplace for existing competitors and new competitors. NewEstablished insurance competitors, emerging under thissuch as The Progressive Corporation, are beginning to explore broader digital platform include, but are not limitedofferings on the Internet, while new competitors, such as Lemonade, Root, Metromile, and Next, continue to Lemonadeemerge. Because the Internet makes it easier and Attune. Reinsurersless expensive to bundle products and services, it also have entered certain primary propertyis possible that companies conducting business on the Internet, in the future, could enter the insurance business or form strategic alliances with insurers. Changes in competitors and casualty insurance markets to diversify their operations and compete with us. Further new competition, particularly on the Internet, could cause changes in the supply or demand for insurance and adversely affect our business.

The increasing importance of the Internet, technology, and digital strategy in our industry also highlights our need to attract and retain employees in difficult-to-fill data science, advanced analytics, and IT roles – and the potential negative impact if we fail in so doing.

We have less loss experience data than our larger competitors.
Insurers rely on their abilityaccess to access reliable data about their customerspolicyholders and loss experience to build complex analytics and predictive models tothat assess therisk profitability, of risks, as well as the potential forreserve adequacy, adverse claim development potential, recovery opportunities, fraudulent activities, and customer buying habits. TheBecause we use and rely on the aggregated industry loss data assembled by rating bureaus under the anti-trust exemptions of the McCarran-Ferguson Act, we likely would be at a competitive disadvantage to larger insurers if Congress repealed the McCarran-Ferguson Act.

We expect the use of data science and analytics willto continue to increase and become more complex and accurate. Theaccurate, particularly with larger sets of relevant data. Some larger competitors have significantly more data about the performance of their underwritten risks. In comparison, we may not have sufficient volumes of loss experience from our insurance operations may not be large or granular enough in all circumstancesdata to analyze and project our future costs. In addition,costs as accurately or granularly. To supplement our data, we have more limiteduse industry loss experience data related to our E&S business, which we purchased in 2011. We use data from ISO, AAIS, NCCI, and NCCI to obtainother publicly available sources. While relevant, industry loss experience to supplement our own data. While statistically relevant, that data ismay not specificcorrelate specifically to the performance of risks we have underwritten. Larger competitors, particularly national carriers, have a significantly larger volume of data regarding the performance of risks that they have underwritten. The analytics of their loss experience data may be more predictive of profitability of their risks than our analysis using, in part, general industry loss experience. For the same reason, should Congress repeal the McCarran-Ferguson Act, which provides an anti-trust exemption for the aggregation of loss data, and we are unable to access data from ISO, AAIS, and NCCI, we will be at a competitive disadvantage to larger insurers who have more loss experience data on their own customersunderwritten and may not need aggregated industry loss data.be as predictive as data on a larger book of our own business.

We depend on distribution partners.
We market and sell our insurance products through distribution partners who are not our employees. We believesubject to various modeling risks that these partners will remain a significant force in overall insurance industry premium production because they can provide customers with a wider choice of insurance products than if they represented only one insurer. However, changes impacting our distribution channel may present challenges and risks to our strategy, including the following:

The availability of products from multiple markets creates competition in our distribution channel and we must market our products and services to our distribution partners before they sell them to our mutual customers.

Growth in our market share is dependent in part on growth in the market share controlled by our distribution partners. The independent retail insurance agencies control approximately 83% of Standard Commercial Lines


business but only 36% of Standard Personal Lines business in the U.S. This, in turn, limits our Standard Personal Lines market opportunity. In addition, in the last several years, both existing and new industry participants have been focusing on developing new platforms that are leveraging technology and the internet to provide a low cost "direct to the customer" distribution model. These efforts may impact the overall market share controlled by our distribution partners and make it more difficult for us to grow or require us to establish relationships with more distribution partners.

There has been a trend towards increased consolidation within our distribution channel, which increases competition among fewer distributors and increases the influence each distribution partner has on our business. Currently, no one distribution partner is responsible for 10% or more of our combined insurance operations' premium.

Our financial condition and results of operations are tied to the successful marketing and sales efforts of our products by our distribution partners. In addition, under insurance laws and regulations and common law, we potentially can be held liable for business practices or actions taken by our distribution partners.

Expansion of our insurance offerings and geographic footprint may create additional risks
Part of our growth strategy includes careful geographic and product expansion. In 2017, we established a Southwest Region when we expanded our Standard Commercial Lines writings into Arizona. We also expanded our Standard Commercial Lines business into New Hampshire in 2017 and on January 1, 2018 we began writing in Colorado. We expect to continue to diversify our book of business through geographic and product expansion. Although diversification of our business is beneficial to our competitive position and long-term results, it exposes us to increased and different risks. Among such increased risks are catastrophic natural risks to which we previously only had limited exposure due to our narrower geographic footprint. These new risks could have a material adverse effectimpact on our business results.
We rely on complex financial and other statistical models, developed internally and by third parties, that predict (i) underwriting results on individual risks and our overall portfolio, (ii) claims fraud and other claims impacts, such as escalation, (iii) impacts from catastrophes, (iv) enterprise risk management capital scenarios, and (v) investment portfolio changes. We rely on these financial and other statistical models to analyze historical loss costs and pricing, trends in claims severity and frequency, the occurrence of operations, liquidity,catastrophe losses, determining reinsurance attachment and exhaustion points, investment performance, portfolio risk, and our economic capital position. Flaws in these financial condition, financial strength, and debt ratings.

other statistical models, or in the embedded assumptions, could lead to increased losses. We believe that statistical models are heavily regulatedextremely valuable in monitoring and changes in regulation may reduce our profitability, increase our capital requirements, and/or limit our growth.
Our Insurance Subsidiaries are heavily regulated by extensive laws and regulations that may change on short notice. The primary public policy behind insurance regulation is the protection of policyholders and claimants over all other constituencies, including shareholders. Historically by virtue of the McCarran-Ferguson Act, our Insurance Subsidiaries are primarily regulated by the states in whichcontrolling risk, but they are domiciled and licensed. State insurance regulation is generally uniform throughout the U.S. by virtue of similar laws and regulations required by the NAIC to accredit state insurance departments so their examinations can be given full faith and credit by other state regulators. Despite their general similarity, various provisions of these laws and regulations vary from state to state. At any given time, there may be various legislative and regulatory proposals in each of the 50 states and District of Columbia that, if enacted, may affect our Insurance Subsidiaries. The types of activities that are regulated by the states include:not a substitute for senior management's experience or judgment.
Pricing and underwriting practices;
28
Claims practices;


Exiting geographic markets and/or canceling or non-renewing policies;
Assessments for guaranty funds and second-injury funds and other mandatory assigned risks and reinsurance;
The types, quality and concentration of investments we make;
Dividends from our Insurance Subsidiaries to the Parent; and
The acquisition of 10% or more of the stock of a company such as Selective, which is an insurance holding company that owns insurance subsidiaries.



The broad regulatory, administrative, and supervisory powers of the various state departments of insurance include the following:
Related to our financial condition, review and approval of such matters as minimum capital and surplus requirements, standards of solvency, security deposits, methods of accounting, form and content of statutory financial statements, reserves for unpaid losses and loss adjustment expenses, reinsurance, payment of dividends and other distributions to shareholders, periodic financial examinations, and annual and other report filings.

Related to our general business, review and approval of such matters as certificates of authority and other insurance company licenses, licensing and compensation of distribution partners, premium rates (which may not be excessive, inadequate, or unfairly discriminatory), policy forms, policy terminations, reporting of statistical information regarding our premiums and losses, periodic market conduct examinations, unfair trade practices, participation in mandatory shared market mechanisms, such as assigned risk pools and reinsurance pools, participation in mandatory state guaranty funds, and mandated continuing workers compensation coverage post-termination of employment.

Related to our ownership of the Insurance Subsidiaries, we are required to register as an insurance holding company system in each state where an insurance subsidiary is domiciled and report information concerning all of our operations that may materially affect the operations, management, or financial condition of the insurers. As an insurance holding company, the appropriate state regulatory authority may: (i) examine our Insurance Subsidiaries or us at any time; (ii) require disclosure or prior approval of material transactions of any of the Insurance Subsidiaries with its affiliates; and (iii) require prior approval or notice of certain transactions, such as payment of dividends or distributions to us.

Although Congress has largely delegated insurance regulation to the various states by virtue of the McCarran-Ferguson Act, we are also subject to federal legislation and administrative policies, such as disclosure under the securities laws, including the Sarbanes-Oxley Act and the Dodd-Frank Act, TRIPRA, OFAC, and various privacy laws, including the Gramm-Leach-Bliley Act, the Fair Credit Reporting Act, the Drivers Privacy Protection Act, the Health Insurance Portability and Accountability Act, and the policies of the Federal Trade Commission. As a result of issuing workers compensation policies, we are subject to Mandatory Medicare Secondary Payer Reporting under the Medicare, Medicaid, and SCHIP Extension Act of 2007. If Congress were to enact laws affecting the oversight of insurer solvency but state regulators remain responsible for rate approval, it is possible that we could be subject to a conflicting and inconsistent regulatory framework that could effect our profitability and capital adequacy.

The European Union enacted Solvency II, which was implemented in 2016 and sets out new requirements for capital adequacy and risk management for insurers operating in Europe.  The strengthened regime is intended to reduce the possibility of consumer loss or market disruption in insurance.  In addition, in 2014, the International Association of Insurance Supervisors proposed Basic Capital Standards for Global Systemically Important Insurers as well as a uniform capital framework for internationally active insurers. Although Solvency II does not govern domestic American insurers, and we do not have international operations, we believe that development of global capital standards will influence the development of similar standards by domestic regulators. The NAIC requires insurers to maintain a framework for identifying, assessing, monitoring, managing, and reporting on the “material and relevant risks” associated with the insurer's (or insurance group's) current and future business plans. ORSA requires companies to file an internal assessment of their solvency with insurance regulators annually. Although no specific capital adequacy standard is currently articulated in ORSA, it is possible that such a standard will be developed over time and may increase insurers' minimum capital requirements, which could adversely impact our growth and return on equity.    
We are subject to non-governmental regulators, such as the NASDAQ Stock Market and the New York Stock Exchange where we list our securities. Many of these regulators, to some degree, overlap with each other on various matters. They have different regulations on the same legal issues that are subject to their individual interpretative discretion. Consequently, we have the risk that one regulator’s position may conflict with another regulator’s position on the same issue. As compliance is generally reviewed in hindsight, we are subject to the risk that interpretations will change over time.

We believe we are in compliance with all laws and regulations that have a material effect on our results of operations, but the cost of complying with various, potentially conflicting laws and regulations, and changes in those laws and regulations could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.



Class action litigation could affect our business practices and financial results.
Our industry has been the target of class action litigation, including the following areas: 

Urban homeowner insurance underwriting practices, including those related to architectural or structural features and attempts by federal regulators to expand the Federal Housing Administration's guidelines to determine unfair discrimination;
Credit scoring and predictive modeling pricing;
Cybersecurity breaches;
Investment disclosure;
Managed care practices;
Prompt and appropriate payment of personal injury protection claims;
Direct repair shop utilization practices;
The use of after-market replacement parts;
Flood insurance claim practices; and
Shareholder class action suits.

If we were to be named in such class action litigation, we could suffer reputational harm with purchasers of insurance and have increased litigation expenses that could have a materially adverse effect on our operations or results.

Risks Related to Our InvestmentInvestments Segment

We are exposed to interest rate risk in our investment portfolio.
We are exposed to interest rate risk primarily related to the market price, and cash flow variability, associated with changes in interest rates. Recent economic data points to increased U.S. and global economic growth, continued low levels of unemployment and signs of rising wages, which compounded with the potential for the pro-growth benefits of the Tax Cuts and Jobs Act of 2017 ("Tax Reform") and the potential for higher federal budget deficits, has recently led to rising U.S. interest rates. A rise in interest rates may decrease the fair value of our existing fixed incomeOur investments and declines in interest rates may result in an increase in the fair value of our existing fixed income investments. Our fixed income securities portfolio, which currently has an effective duration of 3.8 years contains interest rate sensitive instruments that may be adversely affected by changes in interest rates resulting from governmental monetary policies, domestic and international economic and political conditions, and other factors beyond our control. A rise in interest rates would decrease the net unrealized gain position of the investment portfolio, partially offset by our ability to earn higher rates of return on funds reinvested in new investments. Conversely, a decline in interest rates would increase the net unrealized gain position of the investment portfolio, partially offset by lower rates of return on new and reinvested cash in the portfolio. Changes in interest rates have an effect on the calculated duration of certain securities in the portfolio. We seek to mitigate our interest rate risk associated with holding fixed income investments by monitoring and maintaining the average duration of our portfolio with a view toward achieving an adequate after-tax return without subjecting the portfolio to an unreasonable level of interest rate risk. This may include investing in floating rate securities, which currently represent 18% of our fixed income portfolio, and other shorter duration securities that exhibit low effective duration and interest rate risk, but expose the portfolio to other risks, including the risk of a change in credit spreads, liquidity spreads, and other factors that may adversely impact the value of the portfolio. Although we take measures to manage the economic risks of investing in a changing interest rate environment, we may not be able to mitigate the interest rate risk of our assets relative to our liabilities, particularly our loss reserves. In addition, our pension and post-retirement benefit obligations include a discount rate assumption, which is an important element of expense and/or liability measurement. Changes in the discount rate assumption could materially impact our pension and post-retirement life valuation.
We are exposed to credit risk, interest rate fluctuation, and changes in value.
We depend on income from our investment portfolio.
The valueportfolio for a significant portion of our revenue and earnings. Our investments can be negatively affected by liquidity, credit deterioration, financial results, market and economic conditions, political risk, including changes in U.S. Presidential administration, sovereign risk, interest rate fluctuations, or other factors. Our investment portfolioportfolio's value is subject to credit risk from the issuers, and/or guarantors and insurers, of the securities in the portfolio,we hold, and other counterparties in certain transactions and, for certain securities, insurers that guarantee specific issuer’s obligations.transactions. Defaults on any of our investments by theany issuer, or an issuer’s guarantor, insurer, or other counterparties regarding any of our investments,counterparty could reduce our net investment income and net realized investment gains - or result in investment losses. We are subject to the risk that the issuers or guarantors of fixed income securities we own may default on principal and interest payments due underpayment obligations.

Additionally, we are exposed to interest rate risk, primarily related to the terms of the securities. In addition,market price, and cash flow variability associated with changes in interest rates. Consequently, the financial market environmentvalue and sentiment regarding the broad economy may impact the credit spreads demanded by fixed income investors, which in turn may negatively impact the fair market valueliquidity of our fixed income securities. At December 31, 2017, our fixed incomecash, cash equivalents, and marketable and non-marketable securities portfolio represented approximately 92% of our total invested assets, of which approximately 97% were investment grade and 3% were below investment grade rated, resulting in an average credit rating of AA- of the fixed income securities portfolio. Our spread duration, which is reflective of the sensitivity of our fixed income portfolio to changes in credit spread is currently 4.6 years. Over time, our exposure to below investment grade securities and other credit sensitive risk assets may fluctuate as we continue


to diversify the portfolio and take advantage of opportunities to add or reduce risk commensurate with our risk-taking capacity and market conditions. The occurrence of a major economic downturn, acts of corporate malfeasance, widening credit spreads, budgetary deficits, municipal bankruptcies spurred by, among other things, pension funding issues, or other events that adversely affect the issuers or guarantors of these securities could cause the value of our fixed income securities portfolio and our net income to decline and the default rate of our fixed income securities portfolio to increase.
With economic uncertainty, the credit quality of issuers or guarantors could be adversely affected and a ratings downgrade of the issuers or guarantors of the securities in our portfolio could cause the value of our fixed income securities portfolio and our net income to decrease. As our stockholders' equity is leveraged at 3.32:1 to our investment portfolio, a reductionsubstantially. Future fluctuations in the value of our investment portfoliocash, cash equivalents, and marketable and non-marketable securities could result in significant losses and have a material adverse effectimpact on our business, results of operations, financial condition and debt ratings. Levels of write-downs are impacted by our assessment of the impairment, including a review of the underlying collateral of structuredoperating results.

Significant future declines in investment value also could require further losses recorded on securities we intend to sell and our intent and ability to hold securities that have declined in value until recovery. If we reposition or realign portions of the portfolio so that we determine not to hold certain securities in an unrealized loss position to recovery, we will incur an OTTI charge.credit losses.

Our statutory surplusWe have securities tied to LIBOR, which may be materially affectedeliminated by rating downgrades on investments held inthe end of 2021.
As of December 31, 2020, approximately 13% of our portfolio.
We are exposedfixed income securities portfolio was comprised of floating rate securities tied to significant financial and capital markets risks, primarily relatingthe U.S. dollar-denominated London Interbank Offered Rate ("LIBOR"), expected to be eliminated by the end of 2021. The global banking industry has used LIBOR as a primary metric to calculate interest rates credit spreads, equity prices,for numerous types of debt obligations, including personal and commercial loans, interest rate swaps, and other derivative products. In anticipation of LIBOR's elimination, the U.S. Federal Reserve established the Alternative Reference Rates Committee ("ARRC") to select a replacement index for U.S. Dollar LIBOR. The ARRC, comprised of a broad group of private-market participants, including banks, asset managers, insurers, and industry regulators, identified the Secured Overnight Financing Rate ("SOFR") as the recommended benchmark rate to replace LIBOR. SOFR is based on overnight repurchase agreement transactions backed by Treasury securities. The ARRC announced a paced transition plan for this new rate, including specific steps and timelines designed to encourage the adoption of SOFR. We continue to monitor the potential impact, if any, the elimination of LIBOR and the change in market value of our alternative investment portfolio. A decline in both income and our investment portfolio asset values could occur as a result of, among other things, a decrease in market liquidity, fluctuations in interest rates, decreased dividend payment rates, negative market perception of credit risk with respecttransition to types of securities in our portfolio, a decline in the performance of the underlying collateral of our structured securities, reduced returnsSOFR will have on our alternative investment portfolio, or general market conditions. A global decline in asset values will be more amplified in our financial condition, as our statutory surplus is leveraged at a 3.2:1 ratio to our investment portfolio.floating rate investments' performance.
With economic uncertainty, the credit quality and ratings of securities in our portfolio could be adversely affected. The NAIC could potentially apply a more adverse class code on a security than was originally assigned, which could adversely affect statutory surplus because securities with NAIC class codes three through six require securities to be marked-to-market for statutory accounting purposes, as compared to securities with NAIC class codes of one or two that are carried at amortized cost.


We are subject to the types of risks inherent in investing in private limited partnerships.
Our other investments include investments in private limited partnerships that invest in various strategies, such as private equity, private credit, and real assets. SinceThe primary assets and liabilities underlying the investments in these partnerships’ underlying investments consist primarily of assets or liabilities for which there are nolimited partnerships generally do not have quoted prices in active markets for the same or similar assets, theso their valuation of interests in these partnerships is subject to a higher level of subjectivity and unobservable inputs than substantially all of our other investments and as such, is subject to greater scrutiny and reconsideration from one reporting period to the next. Asinvestments. Because these limited partnership investments are recorded under the equity method of accounting, any valuation decreases in the valuation of these investments wouldcould negatively impact our results of operations. We currently expect to increase our allocation to these investments, which may result inproduce additional variability in our net investment income.
We value our investments using methodologies, estimations, and assumptions that are subject to differing interpretations. Changes in these interpretations could result in fluctuations in the valuations of our investments that may adversely affect our results of operations or financial condition.
Fixed income, equity, and short-term investments, which are reported at fair value on our Consolidated Balance Sheet, represented the majority of our total cash and invested assets as of December 31, 2017. As required under accounting rules, we have categorized these securities into a three-level hierarchy, based on the priority of the inputs to the respective valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1). The next priority is to quoted prices in markets that are not active or inputs that are observable either directly or indirectly, including quoted prices for similar assets or liabilities or in markets that are not active and other inputs that can be derived principally from, or corroborated by, observable market data for substantially the full term of the assets or liabilities (Level 2). The lowest priority in the fair value hierarchy is to unobservable inputs supported by little or no market activity and that reflect the reporting entity’s own assumptions about the exit price, including assumptions that market participants would use in pricing the asset or liability (Level 3).
An asset or liability’s classification within the fair value hierarchy is based on the lowest level of significant input to its valuation. We generally use an independent pricing service and broker quotes to price our investment securities. At December 31, 2017, approximately 6% and 93% of these securities represented Level 1 and Level 2, respectively. However, prices provided by independent pricing services and brokers can vary widely even for the same security. Rapidly changing and unprecedented credit and equity market conditions could materially impact the valuation of securities as reported within our


consolidated financial statements (“Financial Statements”) and the period-to-period changes in value could vary significantly. Decreases in value may result in an increase in non-cash OTTI charges, which could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

The determination of the amount of impairmentscredit losses taken on our investments is highly subjective and could materially impact our results of operations or our financial position.
The determination of the amount of impairmentscredit losses taken on our investments is based on our periodic evaluation and assessment of our investments and known and inherent risks associated with the various asset classes. Such evaluations and assessments are revised as conditions change and new information becomes available. Management updates its evaluations regularly and reflects changes in impairments as such evaluations are revised.credit losses at the time of evaluation. There can be no assurance that management has accurately assessed the level of impairmentscredit losses taken as reflected in our Financial Statements. Furthermore, additional impairments may need to be taken in the future. It is possible that interest rates, which are at historic lows, will increase which will result in a reduction in net unrealized gains and may result in net unrealized losses associated with declines in value strictly related to such interest rate movements. It is possible that this could result in realized losses if we sell such securities or possibly more OTTI if we determine we do not have the ability and intent to hold those securities until they recover in value. In addition, we recently hired several new investment managers and expect them to take a more active approach to managing our fixed income securities portfolio. As a result, we expect our OTTI to increase in coming periods based on an increase in securities that we may intend to sell despite being in an unrealized loss position. Historical trends may not be indicative of future impairments.

Risks Related to Evolving Laws, Regulation, and Public Policy Debates

We are subject to complex and changing laws, regulations, and public policy debates that expose us to regulatory scrutiny, potential liabilities, increased costs, reputational harm, and other adverse effects on our business.
Our operations are subject to complex and changing state and federal laws, regulations, and public policy debates on subjects, including, without limitation, the following:
Pricing and underwriting practices;
Claims practices;
Loss and loss adjustment expense reserves;
Exiting geographic markets and/or canceling or non-renewing policies;
Environmental, social, and governance ("ESG") issues, including ESG investment mandates;

Workplace environmental, health, and safety issues.

We continue to monitor and engage in industry and public policy discussions about related legislative and regulatory changes. Changes in tax law couldto laws and regulations can adversely affect our investments results.business by increasing our costs, limiting our ability to offer a product or service to customers, requiring changes to our business practices, or otherwise making our products and services less attractive to customers.
Amendments
If Congress enacted a law directly regulating insurance, particularly insurer solvency oversight, and state regulators remained responsible for rate approval, we could be subject to a conflicting and inconsistent regulatory framework that could impact our profitability and capital adequacy.

While we underwrite risks only in the taxU.S., international regulatory developments, particularly in the European Union (“EU”) related to global capital standards, may influence U.S. regulators as they develop or revise domestic regulatory standards. The International Association of Insurance Supervisors proposed Basic Capital Standards for Global Systemically Important Insurers and a uniform capital framework for internationally active insurers in 2014. Two years later, the EU enacted Solvency II, which established new insurer capital adequacy and risk management requirements intended to reduce the possibility of consumer loss or market disruption by European insurers. Despite these international regulatory changes and continued public policy discussion, RBC remains the NAIC capital adequacy standard. The FIO, in coordination with the Federal Reserve, state regulators, and other regulatory bodies, has been exploring group capital standards. In the fourth quarter of 2020, the NAIC's Group Capital Calculation Working Group adopted the basic structure of its new Group Capital Calculation, along with the model law changes necessary to incorporate it as a requirement for U.S. insurance groups in state law.

We have implemented policies and procedures designed to ensure compliance with applicable laws and regulations. However, we can provide no assurance that our employees, contractors, or independent distribution partners will not violate such laws and regulations of U.S. federal, state,or our policies and local governmentsprocedures. To some degree, we have multiple regulators whose authority may adversely impact us. Our investment portfolio benefits from tax exemptionsoverlap and certain other tax laws, including, non-exhaustively those governing dividends received deductions, and tax-advantaged municipal bond interest. Future federalmay have different interpretations and/or state tax lawregulations related to the same legal issues. This creates the risk that one regulator's position or interpretation may conflict with another regulator on the same issue. The cost of complying with various, potentially conflicting laws and regulations, and changes could lessen or eliminate some or all of these favorable tax advantages, negatively impact the value of our investment portfolio,in those laws and materially and adversely impact our results of operations. In addition, the elimination of the state and local tax deduction (the "SALT deduction") for U.S. taxpayers filing Federal income tax returnsregulations, could have negative consequences to the financial strength of issuers of state and local municipal securities of which we have invested in, which could reduce the value of our investment portfolio, and materially and adversely impact our results of operations. The elimination of the SALT deduction, as well as the lower $750,000 mortgage capa material adverse effect on the deductibility of mortgage interest for U.S. taxpayers, could reduce the value of residential real estate, which could have negative financial consequences to various classes of investments that we have invested in, such as residential mortgage backed securities, and other asset classes backed by mortgages or real estate, and this could reduce the value of our investment portfolio, and materially and adversely impact our results of operations.

Uncertainty regarding domestic and international political developments and their impact on the economy could lead to investment losses, which may adversely affect our results of operations, liquidity, financial condition, liquidity,financial strength, and debt ratings.
As a property and casualty insurance holding company, we depend on income from our investment portfolio for a significant portion of our revenue and earnings. Our investment portfolio is exposed to significant financial and capital market risks, both in the U.S. and abroad. Volatile changes in general market or economic conditions could lead to a decline in the market value of our portfolio as well as the performance of the underlying collateral of our structured securities. The current political climate has created more uncertainty about U.S. domestic and foreign policy that may elevate the volatility of the financial markets and adversely impact our investment portfolio.

Our notes payable and line of credit
Insurers are subject to certain debt-to-capitalizationintense regulatory, political, and media scrutiny. We are subject to government market conduct review and investigations, legal actions, and penalties. There can be no assurance that our business will not be materially adversely affected by the outcomes of such examinations, investigations, or media scrutiny in the future. If we are found to have violated laws and regulations, it could materially adversely affect our reputation, financial condition, and operating results.

Our business is subject to a variety of state, federal, and other laws, rules, policies, and other obligations regarding data protection.
We are subject to federal, state, and international laws relating to the collection, use, retention, security, and transfer of personally identifiable information (“PII”). Federal laws include the Gramm-Leach-Bliley Act, the Fair Credit Reporting Act, the Drivers Privacy Protection Act, the Health Insurance Portability and Accountability Act, and Federal Trade Commission policies. Several states, like New York, Nevada, and California, have passed laws in this area, and other jurisdictions are considering imposing additional restrictions or creating new rights concerning PII. These laws continue to develop and net worth covenantsmay be inconsistent from jurisdiction to jurisdiction. Complying with emerging and changing requirements may cause us to incur substantial costs or require us to change our business practices. Noncompliance could result in significant reputational harm, penalties, and legal liability.

In the same year that it adopted Solvency II, the EU adopted the General Data Protection Regulation ("GDPR"). Effective since 2018 after a significant declinetwo-year implementation period, GDPR regulates data protection and privacy in investment value could impact. Significantthe EU and transfers of personal data outside the EU. GDPR’s main tenet is to give individuals primary control over their personal data. While GDPR has no direct impact on U.S. companies like us without an EU presence, it and any future declines in investment value also could require further OTTI charges. DependingEU data privacy actions may influence U.S. regulators over time.

We make statements about our use and disclosure of PII through our privacy policy, information provided on future market conditions, such as an extreme prolonged market event like the global credit crisis,our website, and other public statements. If we fail to comply with these public statements or federal, state, and international privacy-related and data protection laws and regulations, we could incur additional realizedbe subject to litigation or governmental actions. Such proceedings could impact our reputation and unrealized lossesresult in future periodspenalties, including ongoing audit requirements and significant legal liability.

We are engaged in ordinary routine legal proceedings incidental to our insurance operations that, because litigation outcomes are inherently unpredictable, could adversely impact our reputation and/or have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods.
We are engaged in ordinary routine legal proceedings incidental to our insurance operations that include:
Defense of or indemnity for third-party suits brought against our insureds;
Defense of actions brought against us by our insureds who disagree with our coverage decisions, some of which allege bad faith claims handling and seek extra-contractual damages, punitive damages, or other penalties;
Actions we file, primarily for declaratory judgment, seeking confirmation that we have made appropriate coverage decisions under our insurance contracts;
Actions brought against us or competitors alleging improper business practices and sometimes seeking class status. Such actions historically have included issues and allegations, without limitation, related to (i) unfairly discriminatory underwriting practices, including the impact of credit score usage, (ii) managed care practices, such as provider reimbursement, and (iii) automobile claims practices; and
Actions we file against third parties and other insurers for subrogation and recovery of other amounts we paid on behalf of our insureds.

From time-to-time, legal proceedings in which we are involved may receive media attention based on their perceived newsworthiness and/or relationship to a variety of broad economic, political, social, and legal developments or trends. Such media stories could negatively impact our reputation.

We expect that any potential ultimate liability for ordinary routine legal proceedings incidental to our insurance business will not be material to our consolidated financial condition debt and financial strength ratings, andafter considering estimated loss provisions. Litigation outcomes, however, are inherently unpredictable even with meritorious defenses. The time a case is in litigation also is unpredictable, as state court dockets are increasingly overcrowded. Generally, the longer a case is in litigation the more expensive it can become. Because the amounts sought in certain of these actions are large or indeterminate, any adverse outcomes could have a material adverse effect on our ability to access capital markets.consolidated results of operations or cash flows in particular quarterly or annual periods.

Risks Related to Evolving LegislationOur General Operations


We, face risks regarding our flood business because of uncertainties regarding the NFIP.
We are the fifth largest insurance group in the WYO arrangement of the NFIP, which is managed by the Mitigation Division of FEMA in the U.S. Department of Homeland Security.  Under the arrangement, we receive an expense allowance for policies written and a servicing fee for claims administered, and all losses are 100% reinsured by the Federal Government.  The current expense allowance is 30.9% of DPW. The servicing fee is the combination of 0.9% of DPW and 1.5% of incurred losses.
As a WYO carrier, we are required to follow NFIP procedures in the administration of flood policies and claims.  Some of these requirements may differ from our normal business practices and may present a reputational risk to our brand.  While insurance companies are regulated by the states and the NFIP requires WYO carriers to be licensed in the states in which they operate, the NFIP is a federal program and WYO carriers are fiscal agents of the U.S. Government and must follow the NFIP's directives.  Consequently, we have the risk that directives from the NFIP and a state regulator on the same issue may conflict.



There has been significant public policy and political debate regarding the NFIP and its outstanding debt, including the NFIP's purchase of reinsurance.  Prior to Hurricanes Harvey, Irma, and Maria, in the third quarter of 2017, the NFIP had accumulated debt totaling approximately $25 billion. Losses from the 2017 storms are estimated to total approximately $16 billion and, together with its previously accumulated debt, likely would exceed the NFIP’s total borrowing authority. In response, Congress passed legislation that forgave $16 billion of NFIP debt and allowed recent flood claims to be paid within the program’s $25 billion debt level. In November 2017, the U.S. House of Representatives passed the 21st Century Flood Reform Act, which would extend the NFIP for 5 years, but reduce the WYO reimbursement rate by 3 points from its current 30.9% to 27.9% over a three-year period. The bill also proposes changes in certain operational processes and provides incentives for the private flood markets. The U.S. Senate has yet to consider this bill. While Congress continues to debate a comprehensive reform package, the NFIP has received multiple short-term extensions and is currently authorized through March 23, 2018. We expect the program will continue to operate under a series of short-term extensions, but it may also experience a periodic lapse as it becomes encumbered by other budgetary issues.

Our flood business could be impacted by:  (i) a lapse in program authorization; (ii) any mandate for primary insurance carriers to provide flood insurance; or (iii) private writers becoming more prevalent in the marketplace.  The uncertainty created by the public policy debate and politics of flood insurance reform make it difficult for us to predict the future of the NFIPdistribution partners, and our continued participation in the program.

Wevendors are subject to riskattempted cyber-attacks, other cybersecurity risks, and system availability risk.
Our business heavily relies on IT and application systems that enacted legislation might significantly change insurance regulationmay be accessed from, or are connected to, the Internet. Consequently, a malicious cyber-attack could affect us. Our systems also contain proprietary and adversely impactsconfidential information, including PII, about our business, financial condition, and/operations, employees, agents, and customers and their employees and property. A malicious cyber-attack on (i) our systems, (ii) our distribution partners or the resultstheir key operating systems, and (iii) any other of operations.
We cannot predict what federalour third-party partners or vendors and state rules or legislation will be proposedtheir key operating systems may interrupt our ability to operate, damage our reputation and adopted, or what impact, if any, such proposals or the cost of compliance with such proposals, couldresult in monetary damages that are difficult to quantify, and have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.


In 2009, Congress passed the Dodd-Frank Act
32



We have implemented systems and processes, through encryption and authentication technologies, intended to address corporate governancemitigate or secure our IT systems and control issues identifiedprevent unauthorized access to, or loss of, sensitive data. Our security measures may not be sufficient for all eventualities, as cyber-attacks are continuing to evolve daily. We may be vulnerable to hacking, employee error, malfeasance, system error, faulty password management, or other irregularities. Any disruption or breach of our systems or data security could damage our reputation, result in the financial crises in 2008monetary damages that are difficult to quantify, and 2009 and the non-insurance subsidiaries of American International Group, Inc. One of the key Dodd-Frank Act provisions created the FIO as part of the U.S. Department of Treasury to advise the federal government on insurance issues. Another Dodd-Frank Act provision requires the Federal Reserve, through the Financial Services Oversight Council (“FSOC”), to supervise financial service firms designated as systemically important financial institutions ("SIFI"). We are not and do not expect to be designated ashave a SIFI. Included among Dodd-Frank's corporate governance reforms for public companies were proxy access, say-on-pay, and other compensation and governance issues. A number of Dodd-Frank reform bills have been introduced, but it is uncertain whether any proposal will pass into law.

In general, the Trump Administration and the current Republican majority favor less federal involvement in insurance. Legislative proposals, however, could involve the federal government directly in regulating the business of insurance. President Trump and the Republican congressional majority favor the repeal of the Affordable Care Act ("ACA"). Repeal of the ACA presents some legal and practical challenges. Some reform proposals include a provision to permit sales of insurance across state lines, which is not permitted under current federal law without approval of the respective state insurance regulators. Some ACA reforms call for the elimination of the anti-trust exemptions for health insurers under the McCarran-Ferguson Act. While we are not a health insurer, we and our property and casualty competitors operate under anti-trust exemptions that permit the aggregation of claims and other data in numbers actuarially and statistically sufficient to price insurance. If the MFA were repealed for the property and casualty industry, we would have to seek a business practices exemption from the Department of Justice to share information with other insurers. We cannot predict the impact such a legislative event could havematerial adverse effect on our product and services supplier relationships, results of operations, liquidity, financial condition, financial strength, and debt ratings. To mitigate this risk, we have and expect to continue to (i) conduct employee education programs and tabletop exercises and (ii) develop and invest in a variety of controls to prevent, detect, and appropriately react to cyber-attacks, including frequently testing our systems' security and access controls. We have insurance coverage for certain cybersecurity risks, including privacy breach incidents, which provides coverage up to $30 million above a $1 million deductible. Such coverage may be insufficient to indemnify all losses or types of claims that may arise.


LegislativeIn addition to cyber-attack risk, we face system availability risk. Our business relies heavily on various IT and regulatory proposalsapplication systems that may be impacted by an unplanned loss of availability unrelated to malicious cyber-attacks. A failure in various states sometimes seekone or more systems, including those at facilities where we or our vendors operate systems, may interrupt our ability to limit the ability of insurers to assess insurance risk, including limiting or prohibiting the use of certain factors or predictive measures in propertyoperate and casualty underwriting such as insurance scores and marketplace considerations. These proposals, if enacted, couldnegatively impact underwriting pricing andour results of operations.




Risks RelatedOur long-term strategy to Our General Operations
The failuredeploy operational leverage is dependent on the success of our risk management strategies, and their failure could have a material adverse effect on our financial condition or results of operations.
As an insurance provider, it is our business to take oninsurer, we assume risk from our customers.policyholders. Our long-term strategy includes the use of above averageabove-average operational leverage, which can be measured as the ratio of NPW to our equity or policyholderspolicyholders' surplus. We balance and mitigate our operational leverage risk with a number ofseveral risk management strategies within our insurance operations to achieve a balance of growth and profit, andincluding purchasing significant amounts of reinsurance, a disciplined approach to reduce our exposure. These strategies include, but are not limited to, the following:
Being disciplined in our underwriting practices;
Being prudent in our claims management practices, establishing adequate lossreserving, and loss expense reserves, and placing appropriate reliance on our claims analytics;
Continuing to develop and implement various underwriting tools and automated analytics to examine historical statistical data regarding our customers and their loss experience to: (i) classify such policies based on that information; (ii) apply that information to current and prospective accounts; and (iii) better predict account profitability;
Continuing to develop our customer experience platform as we grow in our understanding of customer segmentation;
Purchasing reinsurance and using catastrophe modeling; and
Being prudent in our financial planning process, which supports our underwriting strategies.

We also maintain a conservative approach to our investment portfolio management and employ risk management strategies that include, but are not limited to:
Being prudent in establishing our investment policy and appropriately diversifying our investments, which supports our liabilities and underwriting strategies;
Using models to analyze historical investment performance and predict future investment performance under a variety of scenarios using asset concentration, asset volatility, asset correlation, and systematic risk; and
Closely monitoring investment performance, general economic and financial conditions, and other relevant factors.

All of thesephilosophy. These strategies have inherent limitations. We cannot be certain that an event or series of unanticipated events will not occur and result in losses greater than we expect and have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.


Operational risks, including human or systems failures, are inherent in our business.
Operational risks and losses can result from, among other things, fraud, errors, failure to document transactions properly or to obtain proper internal authorization, failure to comply with regulatory requirements, information technology failures, or external events.
Our predictive models for underwriting, claims, and catastrophe losses, as well as our business analytics and our information technology and application systems are critical to our business. We expect our information technology and application systems to remain an important part of our underwriting process and our ability to compete successfully. A major defect or failure in our internal controls or information technology and application systems could: (i) result in management distraction; (ii) harm our reputation; or (iii) increase our expenses. We believe appropriate controls and mitigation procedures are in place to prevent significant risk of a defect in our internal controls around our information technology and application systems, but internal controls provide only a reasonable, not absolute, assurance as to the absence of errors or irregularities and any ineffectiveness of such controls and procedures could have a significant and negative effect on our business.



Rapid development of new technologies may result in an unexpected impact on our business and insurance industry overall.
Development of new technologies continues to impact all aspects of business and individuals’ lives at rapid speed.  Often such developments are positive and gradually improve standards of living and speed of communications, and allow for the development of more efficient processes.  The rapid development of new technologies, however, also presents challenges and risks.  Examples of such emerging risks include, but are not limited to:
Change in exposures and claims frequency and/or severity due to unanticipated consequences of new technologies and their use.  For example, technologies have been developed and are being tested for autonomous self-driving automobiles.  It is unclear and we cannot predict the corresponding impact to automobile claims.  It is possible that these technological developments will affect the profitability and demand for automobile insurance.
Changes in how insurance products are marketed and purchased due to the availability of new technologies and changes in customer expectations.  For example, comparative rating technologies, which are widely used inpersonal lines insurance, facilitate the process of efficiently generating quotes from multiple insurance companies.  This technology makes differentiation based upon factors other than pricing more difficult and has increased price comparisons, resulting in a higher level of quote activity with a lower percentage of quotes becoming new business written.  These trends may continue to accelerate and may affect other lines of business, which could put pressure on our future profitability and growth.
New technologies may require the development of new insurance products without the support of sufficient historical claims data for us to continue to compete effectively for our distribution partners' business and customers.    

We depend on key personnel.
To a large extent, our business' success depends on our ability to attract and retain key employees. Competition to attract and retain key personnel is intense. While we have employment agreements with certain key managers, all of our employees are at-will employees and we cannot ensure that we will be able to attract and retain key personnel. As of December 31, 2017, our workforce had an average age of approximately 47 and approximately 18% of our workforce was retirement eligible, which we define as including individuals who are 55 years of age and have 10 or more years of service.
We are subject to a variety of modeling risks, which could have a material adverse impact on our business results.
We rely on complex financial models, such as predictive underwriting models, a claims fraud model, third party catastrophe models, an enterprise risk management capital model, and modeling tools used by our investment managers, which have been developed internally or by third parties to analyze historical loss costs and pricing, trends in claims severity and frequency, the occurrence of catastrophe losses, investment performance, and portfolio risk. Flaws in these financial models, or faulty assumptions used by these financial models, could lead to increased losses. We believe that statistical models alone do not provide a reliable method for monitoring and controlling risk. Therefore, such models are tools and do not substitute for the experience or judgment of senior management.

We are subject to attempted cyber-attacks and other cybersecurity risks.
Our business heavily relies on various information technology and application systems that are connected to, or may be accessed from, the Internet and may be impacted by a malicious cyber-attack. Our systems also contain confidential and proprietary information regarding our operations, our employees, our agents, and our customers and their employees and property, including personally identifiable information. A malicious cyber-attack on our systems or those of our vendors may interrupt our ability to operate and impact our results of operations. We have, and expect to continue to, develop and invest in a variety of controls to prevent, detect, and appropriately react to cyber-attacks, including frequently testing our systems' security and access controls. Cyber-attacks continue to become more complex and broad-ranging, and our internal controls provide only a reasonable, not absolute, assurance that we will be able to protect ourselves from significant cyber-attack incidents. By outsourcing certain business and administrative functions to third parties, we may be exposed to enhanced risk of data security breaches. Any breach of our systems or data security could damage our reputation and/or result in monetary damages that, in turn, could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings. Although we have not experienced a material cyber-attack, it is possible that it might occur. We have insurance coverage for certain cybersecurity risks, including privacy breach incidents, that provides protection up to $20 million above a deductible of $1 million. In addition, within our Standard Commercial Lines segment, we offer cyber-related insurance products for which we have mitigated the majority of the related risk through protection under our reinsurance treaties.



Given the increased number of identity thefts from cyber-attacks, federal and state policymakers have, and will likely continue to propose increased regulation of the protection of personally identifiable information and appropriate protocols after a related cybersecurity breach. The New York Department of Financial Services recently adopted a cyber protection and reporting regulation for financial services companies with which we are complying. The NAIC also has adopted a model regulation based upon the New York regulation, and we expect other states to consider adoption of the NAIC model in 2018. Compliance with these regulations and efforts to address continually developing cybersecurity risks may result in a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

Changes in tax law could adversely affect our results of operations and financial condition.
We are subject to the tax laws and regulations of U.S. federal, state, and local governments, and their amendment could adversely impact us. For example, the U.S. tax code was recently amended to reduce the federal corporate income tax rate from 35% to 21% effective for the 2018 tax year. As a result, our deferred tax assets were reduced and we were required to recognize a reduction of a previously-recognized federal tax benefit in the fourth quarter of 2017, when enacted. Potential future tax rule changes may increase or decrease our actual tax expense and could materially and adversely affect our results of operations.

If we experience difficulties with outsourcing relationships, our ability to conduct our business might be negatively impacted. 
We currently outsource certain business and administrative functions to third parties for expediency, efficiency and economies of scale and this outsourcing may increase in the future. If we or our third-party partners falter in the development, implementation, or execution of our outsourcing strategies, we may experience operational difficulties, increased costs, and customer losses that may have a material adverse effect on our results of operations or financial condition. We have supplemental staffing service agreements with multiple consulting, information technology, and service providers that supply approximately 47% of our skilled technology capacity. These resources are principally based in the U.S., although some of the resources are foreign. The impact of the recently-enacted U.S. tax reform on the availability and cost of these services is still uncertain.

Item 3. Legal Proceedings.

In the ordinary course of conducting business,Incidental to our insurance operations, we are named as defendantsengaged in variousordinary routine legal proceedings. Most of these proceedings that, because litigation outcomes are claims litigation involving our Insurance Subsidiaries as either: (i) liability insurers defending or providing indemnity for third-party claims brought against our customers; or (ii) insurers defending first-party coverage claims brought against them. We account for such activity through the establishment of unpaid losses and loss expense reserves. We expect that any potential ultimate liability in such ordinary course claims litigation will not be material to our consolidated financial condition, results of operations, or cash flows after consideration of provisions made for potential losses and costs of defense.
From time to time, our Insurance Subsidiaries also are named as defendants in other legal actions, some of which assert claims for substantial amounts. These actions include, among others, putative class actions seeking certification of a state or national class. Such putative class actions have alleged, for example, improper reimbursement of medical providers paid under workers compensation and personal and commercial automobile insurance policies. Similarly, our Insurance Subsidiaries are also named from time-to-time in individual actions seeking extra-contractual damages, punitive damages, or penalties, some of which allege bad faith in the handling of insurance claims. We believe that we have valid defenses to these cases. We expect that any potential ultimate liability in any such lawsuit will not be material to our consolidated financial condition, after consideration of provisions made for estimated losses. Nonetheless, given the inherent unpredictability of litigation and the large or indeterminate amounts sought in certain of these actions, an adverse outcome in certain mattersinherently unpredictable, could possibly have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods.



For additional information regarding our legal risks, refer to Item 1A. “Risk Factors.” and Note 21. "Litigation" included in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K. As of December 31, 2017,2020, we do not believe the Company or any of the Insurance Subsidiaries was a defendant in anyhave no material pending legal actionproceedings that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

There can beWe offer no assuranceassurances that actual results will notbe the same as those estimates, and it is possible they will differ from those estimates. Thosematerially. The policies and estimates that werewe consider most critical to the preparation of the Financial Statements involved the following: (i) reserves for loss and loss expense;expense, (ii) pensioninvestment valuations and post-retirement benefit plan actuarial assumptions;the allowance for credit losses on available-for-sale ("AFS") fixed income securities, (iii) investment valuationreinsurance, (iv) allowance for credit losses on premiums receivable, and other-than-temporary-impairments (“OTTI”); and (iv) reinsurance.(v) accrual for auditable premium.

How reserves are established
Each quarter, our internal actuaries prepare a comprehensive loss and loss expense reserve analysis. This analysis uses standard actuarial projection techniques, applied to our own loss and loss expense experience, to produce updated ultimate loss and loss expense estimates. In addition, other non-standard approaches may be considered. The results of the reserve analysis are then discussed with management in order to determine if any changes are required to the estimated ultimate loss and loss expense reserves. In addition to the actuarial loss and loss expense projections, management also considers other information and factors. Other considerations include internal impacts such as changes to our underwriting and claims practices, as well as external impacts, such as economic, legal, judicial and social trends. Upon considering all of this information, management makes a decision regarding changes to the reserve estimates.
The actuarial reserve analysis is the foundation of the quarterly reserve review process. Using generally accepted actuarial reserving techniques, we project our estimate of ultimate loss and loss expense at each reporting date. Our IBNR reserve is the difference between the projected ultimate loss and loss expense incurred and the sum of: (i) case loss and loss expense reserves; and (ii) paid loss and loss expense. The actuarial techniques used in determining ultimate losses are part of a comprehensive reserving process that includes two primary components. The first component is a detailed quarterly reserve analysis performed by our internal actuarial staff. In completing this analysis, the actuaries must gather substantially similar data in sufficient volume to ensure statistical credibility of the data, while maintaining appropriate differentiation. This process defines the reserving segments, to which various actuarial projection methods are applied. When applying these methods, the actuaries are required to make numerous assumptions including, for example, the selection of loss and loss expense development factors and the weight to be applied to each individual projection method. These methods include paid and incurred versions of the following methods: aggregate loss and loss expense development, Bornhuetter-Ferguson, Berquist-Sherman, and frequency/severity modeling (via a development approach). The second component of the analysis is the projection of the expected ultimate loss and loss expense ratio for each line of business for the current accident year. This projection is part of our planning process wherein we review and update expected loss and loss expense ratios each quarter. This review includes actual versus expected pricing changes, loss and loss expense trend assumptions, and updated prior period loss and loss expense ratios from the most recent quarterly reserve analysis. Actual claims counts and severities are also considered relative to initial expectations.


In addition to the quarterly reserve analysis, a range of possible IBNR reserves is estimated annually and continually considered, among other factors, in establishing IBNR for each reporting period. Loss and loss expense trends are also considered, which include, but are not limited to, large loss activity, asbestos and environmental claim activity, large case reserve additions or reductions for prior accident years, and reinsurance recoverable issues. We also consider factors such as: (i) per claim information; (ii) company and industry historical loss experience; (iii) legislative enactments, judicial decisions, legal developments, and changes in political attitudes; and (iv) trends in general economic conditions, including the effects of inflation. Based upon our quarterly reserve analysis, our annual reserve range, and other relevant factors and considerations, IBNR is established and the ultimate net liabilityReserves for loss and loss expense is determined. Such an assessment requires considerable judgment givenincludes case reserves on reported claims and reserves known as incurred but not reported ("IBNR") reserves.  Case reserves are estimated on each individual claim, and based on claim-specific facts and circumstances known at the time.  The case reserves may be adjusted upward or downward as the specific facts and circumstances change. IBNR reserves are established at more aggregated levels and include provisions for (i) claims not yet reported, (ii) future development on reported claims, (iii) previously closed claims that it is frequently not possible to determine whether a changewill be reopened in the data is an anomaly until sometime after the event. Even if a change is determinedfuture, and (iv) anticipated salvage and subrogation recoveries. For additional information on our accounting policy for reserves for loss and loss expense, refer to be permanent, it is not always possibleNote. 2. “Summary of Significant Accounting Policies” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.
Our robust reserve process relies upon internal reserve reviews performed quarterly, based upon our own loss experience, with consideration given to reliably determine the extent of the change until sometime later. There is no precise method for subsequently evaluating the impact of any specific factor on the adequacy of reserves because the eventual deficiency or redundancy is affected by manyvarious internal and external factors. The changes in these estimates, resulting from the continuous review process and the differences between estimates and ultimate payments, are reflected in the Consolidated Statements of Income for the period in which such estimates are changed. Any changes in the liability estimate may be material to the results of operations in future periods. In addition to our internal review, statutory regulation requires us toreserve reviews, we have a Statement of Actuarial Opinion issued annually on our statutory reserve adequacy. We engage an external consulting actuary perform an independent review of our reserves semi-annually. We do not rely on the external consulting actuary's report for recording our reserves; however, we do review and discuss our respective observations regarding trends, key assumptions and actuarial methodologies. While not required to issue this opinion based on theirbe performed by an independent review.external actuary, our independent external actuary issues the annual statutory Statements of Actuarial Opinion for our Insurance Subsidiaries.
Range of reasonable reservesreserve estimates
We have estimated a range of reasonably possible reservesreserve estimates for net loss and loss expense claims to be $2,899of $3,250 million to $3,361$3,893 million at December 31, 2017, which compares to $2,780 million to $3,237 million at December 31, 2016. These ranges reflect2020. This range reflects low and high reasonable reserve estimates which weredetermined by judgmentally adjusting the methods, factors and assumptions selected primarily by consideringwithin the internal reserve review. This approach produces a range of indications calculated using generally accepted actuarial techniques. Such techniques assume that past experience, adjusted for the effectsreasonable reserve estimates, as opposed to a distribution of current developments and anticipated trends, are an appropriate basis for predicting future events. Although these reflect ranges of reasonable estimates,all possible outcomes. Therefore, it is possible that the final outcomes may fall above or below these amounts. The ranges dorange does not include a provision for potential increases or decreases associated with asbestos, environmental, and certain other continuous exposure claims, aswhich by their nature are more variable and, therefore, traditional actuarial techniques cannot be effectively applied to these exposures.applied.

Major developments related to loss and loss expense reserve estimates and uncertainty
The Insurance Subsidiaries are multi-state, multi-line property and casualty insurance companies and, as such, are subject to reserve uncertainty stemming from a variety of sources. These uncertainties are considered at each step in the process of establishing loss and loss expense reserves. As market conditions change, certain developments may occur that increase or decrease the amount of uncertainty. These developments include impacts within our own paid and reported loss and loss expense experience, as well as other internal and external factors that have not yet manifested within our data, but may do so in the future. All of these developments are considered when establishing loss and loss expense reserves, and in estimating the range of reasonable reserves.reserve estimates as of December 31, 2020 has expanded relative to December 31, 2019. This is partially due to the growth in reserves commensurate with our growth in net premiums earned ("NPE"), but also recognizes the additional risks in the reserve portfolio presented by the unique legislative, judicial, economic and social environment resulting from COVID-19. Some of these uncertainties may not be resolved for an extended period of time.

A detailed discussion of recent reserve developments,development by line of business follows.


Standard Market General Liability Line of Business
At December 31, 2017,2020, our general liability line of business had recorded reserves, net of reinsurance, of $1.1$1.4 billion, which represented 36%38% of our total net reserves. In 2017,2020, this line experienced favorable development of $48.3$35.0 million, attributable to lower than expected frequencies andloss severities mainly in accident years 20162017 and prior.


During 2016,2019, this line experienced favorable development of $45.0$5.0 million, attributable mainly to lower than anticipated claimsloss severities in accident years 2008 through 20132015 and 2015.2016, partially offset by increases in the 2017 and 2018 accident year.

By its nature, this line presents a diverse set of exposures,exposures. General liability losses and therefore can beloss trends are influenced by a variety of factors.factors, including legislative enactments, judicial decisions, and economic and social inflation. Economic inflation directly impacts our claims severities, such as increasing costs of raw materials, medical procedures and labor costs. Social inflation may impact both the frequency and severity of claims by impacting (i) the propensity for a claimant to file a claim, (ii) the percentage of claimants who engage lawyers, and (iii) the nature of judicial verdicts and amount of the associated awards.

We have exposure to abuse or molestation claims through insurance policies that we (i) principally underwrite through our Community and Public Services ("CAPS") strategic business unit and (ii) issue to schools, religious institutions, day-care facilities, and other social services. Through 2017, our exposure to abuse or molestation risk had been increasing, reflective of the growth in our CAPS book. In recent years,2018, we introduced more stringent underwriting eligibility guidelines and partnered with a third party to better assess exposure and introduce greater loss control measures. In 2019, we filed and approved significant rate increases for this exposure. These actions have limited our growth in this strategic business unit.

We also have exposure to abuse or molestation claims from recently enacted state laws that extend the line has been favorably impactedstatute of limitations or permit windows for abuse or molestation claims and lawsuits to be filed that statutes of limitations previously barred. Consequently, we may receive claims decades after the alleged acts occurred for policies issued by decreasing frequenciespredecessor companies that will involve complex claims coverage determinations, potential litigation, and relatively benign severity trends. As the economy continuesneed to improve it is possible thatcollect from reinsurers under older reinsurance agreements.

To better understand our exposure to abuse or molestation, we have instituted enhanced claims coding to identify and classify abuse or molestation claims. Our claims and actuarial departments actively monitor these trends will be affected. Our actuarial department actively monitors these trends within our reserve review data, and holds frequent discussions with claims to identify changes in frequency or severity and any potential shiftsemerging or shifting trends. While these actions should help us better understand this rapidly evolving exposure, the ultimate impact of social, political, and legal trends remains highly uncertain, and — as a result — our loss and loss expense reserves remain highly uncertain.

The COVID-19 pandemic presents additional risk to this line in these trends.several forms. First, as businesses reopen, they may be susceptible to claims alleging customers contracting COVID-19 due to unsafe business practices. Hiring practices may also be called into question as businesses re-staff. In addition to COVID-19-specific claims, changes in claims reporting or settlement

practices may have been, and may continue to be, affected by several factors, including individual's propensity to bring a claim during the shut-down, court closures, and other behavioral and procedural changes.

Standard Market Workers Compensation Line of Business
At December 31, 2017,2020, our workers compensation line of business recorded reserves, net of reinsurance, of $966.5$870 million, which represented 30%23% of our total net reserves. During 2017,2020, this line experienced favorable development of $52.3$60.0 million, driven by accident years 20162018 and prior. During 2016,2019, this line experienced favorable development of $56.0$68.0 million, driven by accident years 20142017 and prior. During 2017,both 2020 and 2019, this line again showedexperienced lower loss emergence than expected, due, in part, to: (i) lower medical inflation than originally anticipated; (ii) our proactive underwriting actions in recent years;actions; and (iii) various significant claims initiatives that we have implemented. Because of the length of time that injured workers receive medical treatment, decreases in medical inflation can cause favorable loss development across an extended number of accident years.


While we believe thesethe underwriting and claims operational changes are significant drivers ofimproved our improved lossunderwriting experience, there is alwaysalso risk associated with change. Most notably, these changes in operations may inherently change paid and reported development patterns. While our reserve analyses incorporate methods that adjust for these changes, there nevertheless remains a greater risk of fluctuation in the estimated reserves.
In addition to the uncertainties associated with our actuarial assumptions and methodologies, described above, the workers compensation line of business can be impacted by a variety of other issues, such as the following:


Unexpected changes in medical cost inflation - The industry is currently experiencing a period of lower claim cost inflation. Changes in our historical workers compensation medical costs, along with uncertainty regarding future medical inflation, creates the potential for additional variability in our reserves;


Changes in statutory workers compensation benefits - Benefit changes may be enacted that affect all outstanding claims, regardless of havingincluding claims that have occurred in the past. Depending upon the social and political climate, these changes may either increase or decrease associated claim costs;


Changes in utilization of the workers compensation system - These changes may be driven by economic, legislative, or other changes. For example, this includeschanges, such as increased use of pharmaceuticals, and more complex medical procedures.procedures, changes in the life expectancy of permanently-injured workers, and availability of health insurance, among others.

Audit premium and endorsement premiumCOVID-19-related impacts - While we are not a major insurer of front-line workers (e.g. medical, hospital, etc.), we do have potential exposure to employees contracting COVID-19 in the course of their employment. These claims may also introduce uncertainty into our reserves, since earned premiums are used as a basisbe asserted under "presumption statutes" implemented by certain states, shifting the burden of proof from the claimant to set initial reserves. Over recent years, this activity has been fairly consistent. In 2017, audit and endorsement activity resulted in additional premiumthe insurer. Furthermore, the significant impact to unemployment, coupled with injured workers delaying non-essential procedures, may extend the duration of $18.2 million, and in 2016 it resulted in additional premium of $22.6 million.non-COVID-19 claims.

Standard Market Commercial Automobile Line of Business
At December 31, 2017,2020, our commercial automobile line of business had recorded reserves, net of reinsurance, of $475$645 million, which represented 15%17% of our total net reserves. In 2017,2020, this line experienced unfavorable prior year development of $35.6$7.1 million, which was mainly driven by increaseshigher loss severities in accident years 20122016 through 2016, due to2019 and higher than expected frequency and severity.

For the industry, the commercial automobile line hashad experienced unfavorable trends in recent years, in both its casualty and property coverages. We believe the increasedyears. Increased frequencies are largelywere likely due to increased miles driven as a result of lower


unemployment and lower gasoline prices, coupled with poor road quality, as well as an increase in distracted driving. RisingThe onset of the COVID-19 pandemic in early 2020, along with governmental "stay-at-home" orders, dramatically reduced miles driven and road traffic, significantly reducing claims frequency. While miles driven has increased, activity remains modestly below expected levels. Conversely, both entering the pandemic and post-pandemic, we have seen rising severities on both bodily injury and property damage claims. The average value of our bodily injury paid loss settlements has increased, which may relate to a trend we have seen of more claimants using attorneys in the claims process. Increasing property damage severities may be tied to the result of the increasing complexity of vehicles and the technology they incorporate, which results in increased repair costs.costs for increasingly complex vehicles that incorporate more technology. These trends may be further exacerbated during the economic slow-down, where less vehicles were on the road, but driving at higher speeds.


We are currently takingOver the last several years, we have taken actions to improve the profitability of this line of business, including:

Taking meaningful rate and underwriting actions on our renewal portfolio. We will continue to leverage our predictive modeling and analytical capabilities to provide more granular insights as toabout where best towe should focus our actions.
Aggressively managing new business pricing and hazard mix, co-underwriting selected higher hazard classes by the field and home office, providing better recognition of risk drivers, and improved pricing.

Reducing premium leakage by improving the quality of our rating information. This includes validating application information using third partythird-party data and obtaining more detailed driver information.
ExploringImplementing new tools to score drivers to underwrite more effectively and align rate with exposure.


Standard Market Personal Automobile Line of Business
At December 31, 2017,2020, our personal automobile line of business had recorded reserves, net of reinsurance, of $97$98 million, which represented 3% of our total net reserves. In 2017,2020, this line experienced unfavorablefavorable prior year reserve development of $6.7$1.8 million, mainly attributable to an increaselower loss severities in accident years 2011 through 2016. Thisyear 2019. In 2019, this line experienced unfavorable prior year reserve development of $1.0$4.4 million, mainly attributable to higher loss severities in 2016.accident year 2018.


Some of the driverssame issues affecting the commercial automobile line are also affecting this line. Increased usageFurthermore, the COVID-19-related impact of reduced frequency was more pronounced in this line, with similar potential for higher average severities. Aside from the COVID-19-related temporary impacts, the underlying trends of increased miles driven and vehicle repair costs, coupled with social trends such aspoor road quality, and distracted driving, are likely causes of increased frequencies and rising severities. We continue to recalibrate our predictive models as well asand refine our underwriting and pricing approaches. While we believe these changes will ultimately lead to improved profitability and greater stability, theythe resulting changes to our exposure profile may impact paid and reported development patterns, thereby increasing the uncertainty in the reserves in the near-term.


E&S Casualty Lines of Business
At December 31, 2017,2020, our E&S casualty lines of business had recorded reserves, net of reinsurance, of $306$405 million, which represented 10%11% of our total net reserves.

In 2020, we created a dedicated E&S claims team within our target return. In ordercorporate claims function to improve outcomes, we have taken the following actions relatedbring greater expertise and consistency to E&S casualty claims:claims handling.

Over the course of late 2015 and early 2016, our E&S claims handling function was aligned with our standard operations claims function. E&S claims were migrated from the business unit in Scottsdale, Arizona, to the appropriate regional claims operation. Complex claims are referred to the corporate Complex Claims Unit ("CCU") for specialized handling.
Claims have been segregated into “litigated” versus “non-litigated.” Separate claim handlingand “non-litigated” categories, separate teams have been created, with the requiredspecialized skill sets to appropriately handle these two types of claims.handling each category.
We implemented the following operational and expense improvement initiatives regardingfor outside adjusters and legal counsel:

Utilized staff coverage attorney for coverage reviews;
Heightened focus on legal budgeting and expense management;
Required panel counsel firms to use our electronic legal billing and budgeting system to better manage budgets and expenses associated with litigation; and
Implemented a panel counsel review process.

Other impacts creating additional loss and loss expense reserve uncertainty


Claims Initiative Impacts
In additionConsistent with our strategic imperative to the line of business specific issues mentioned above, our lines of business have been impacted by a number of initiatives undertaken byoptimize operational efficiency, our Claims Department is continually identifying areas for improvement and efficiency to increase our value proposition to policyholders. These improvements may lead to changes in claims practices that have resulted in variability, or shifts, in theaffect average level of case reserves. Some of these initiatives have also impactedreserve levels and claims settlement rates. These changes affectrates, which directly impact the data upon which theused to project ultimate loss and loss expense projections are made.expense. While these changes may increase uncertainty in case reserve levels and settlement rates increase the uncertaintyour estimates in the short run,term, we expect the longer-term benefit will be a more refined management of the claims process.process to be the longer-term benefit.


SomeCOVID-19 presented some unique dynamics within our Claims department. Particularly during the early part of the specific actions implementedpandemic, with less new claims being reported, the claims department placed greater focus on the existing claims inventory, leading to a speed-up of claim closures. This speed-up stabilized over the past several years, in additioncourse of the year, with closure rates returning closer to those regarding E&S as discussed above, are as follows:pre-pandemic levels.
Increased focus on reducing workers compensation medical costs through more favorable Preferred Provider Organization ("PPO") contracts and greater PPO penetration.
A more comprehensive approach for handling workers compensation claims, with an emphasis towards improving recovery times, allowing for earlier “return-to-work.” This involves elevated and proactive case management in the areas of medical, pharmaceutical, and physical therapy treatments.
The continued use of our CCU, to which all significant and complex liability claims are assigned. This unit has been staffed with personnel that have significant experience in handling and settling these types of claims.
The strategic realignment of our CMS model to handle property claims under $5,000.
The continued use of our Property Claims Specialists ("PCS") and our Property Large Loss Unit ("LLU"). Our PCSs handle claims between $5,000 and $100,000, while the LLU handles claims above $100,000. Both groups form the core of our catastrophe response team. During 2016, we began increasing the number of property claims specialists to respond to property claims with higher severity and/or complexity. This provides us with more staff to respond to claim volume, including the fluctuations that result from catastrophes, while ensuring we have the highest level of property expertise available to apply to our more complex claims.
Continued efforts in the areas of fraud investigation and salvage/subrogation recoveries. These efforts have been supported by the introduction of predictive models that allow us to better focus our efforts.


Our internal reserve analyses incorporate certain actuarial projection methods whichthat make adjustments for changes in case reserve adequacy and claims settlement rates. These methods adjust our historical loss experience to the current level of case adequacy

or settlement rate, which provides a more consistent basis for projecting future development patterns. These methods have their own associated assumptions and judgments associated with them, so as withand, like any projection method, they are not definitive in and of themselves. Furthermore, given that the expected benefits from our claims initiatives take time to fully manifest, we do not take full credit for the anticipated benefit in establishing our loss and loss expense reserves. These initiatives may prove more or less beneficial than currently reflected, which will affect development in future years. Our various projection methods provide an indication of these potential future impacts. These impacts would be greatest within our larger reserve lines of workers compensation, general liability, and commercial automobile liability, within the more recent accident years.


Economic Inflationary Impacts
Current United States ("U.S.") monetary policy and global economic conditions may bring additional uncertainty related to inflationary trend. Changes in inflation affect the ultimate settlement costs for many of our lines of business, with the greatest impact in the long-term given the length of time required for claim settlement and the impact of medical cost trends relating to longer-taillonger-tailed lines such as general liability and workers compensation claims. In addition, recent economic data points to increased U.S. and global economic growth, continued low levels of unemployment and signs of rising wages, which compounded with the potential for the pro-growth benefits of the Tax Cuts and Jobs Act of 2017 ("Tax Reform") and the potential for higher Federal budget deficits, has recently led to rising U.S. interest rates and may result in a higher level of inflation in 2018 and beyond. Uncertainty regardingcompensation. Therefore, uncertainty about future inflation or deflation creates the potential for additional volatilityreserve variability in our reserves for these lines of business.
 
Sensitivity analysis: Potential impact on reserve uncertainty due to changes in key assumptions
Our process to establish reserves includes a variety of key assumptions, including but not limited to, the following:without limitation:
The selection of loss and loss expense development factors;
The weight to be applied to each individual actuarial projection method;
Projected future loss trends; and
Expected claim frequencies, severities, and ultimate loss and loss expense ratios for the current accident year.



The importance of any single assumption depends on several considerations, such as the line of business and the accident year. If the actual experience emerges differently than the assumptions used in the process to establish reserves, changes in our reserve estimate are possible andthat may be material to the results of operations in future periods. Set forth belowBelow are sensitivity tests that highlight potential impacts to loss and loss expense reserves under different scenarios, for the major casualty lines of business.business under different scenarios. These tests consider each assumption and line of business individually, without any consideration of correlation between lines of business and accident years. Therefore, the results in the tables below do not constitute an actuarial range. While the figures represent possible impacts from variations in certain key assumptions, as identified by management, there is no assurance that the future emergence of our loss and loss expense experienceemergence will be consistent with either our current or alternative sets of assumptions.


While the sources of reserve variability discussed above are generated by different internal and external trends and operational changes, they ultimately manifest themselves as changes in the expected loss and loss expense development patterns. These patterns are a key assumption in the reserving process. In addition, to the expected development patterns, thecurrent accident year expected loss and loss expense ratios are anotheralso a key assumption in the reserving process.assumption. These expected ratios are developed through a rigorous process of projecting recent accident years' experience to an ultimate settlement basis, and then adjusting itthem to the current accident year's pricing and loss cost levels. Impact from changes in the underwriting portfolio and changes into claims handling practices are also quantified and reflected where appropriate. As is the case with all estimates, the ultimate loss and loss expense ratios may differ from those currently estimated.


The sensitivities of loss and loss expense reserves to these key assumptions are illustrated below for the major casualty lines. The first table shows thedisplays estimated impacts from changes in expected reported loss and loss expense development patterns.patterns for our major casualty lines of business. It shows reserve impacts by line of business if the actual calendar year incurred amounts are greater or less than current expectations by the selected percentages.

Note that there is some overlap between the impacts in the two tables. For example, increases in the calendar year development would ultimately impact our view of the current accident year's loss and loss expense ratios. Nevertheless,However, these tables provide perspective intoon the sensitivity of each key assumption. While the changes represent outcomes based on reasonably likely changes to our underlying reserving assumptions, they do not represent a full range of these key assumptions.possible outcomes. Our reserves could increase or decrease significantly more or significantly less than what the tables above reflect.


Asbestos and Environmental Reserves
Our general liability, excess liability, and homeowners reserves include exposure to asbestos and environmental claims. Our exposure to environmental liability is primarily due to: (i) landfill exposures from policies written prior to the absolute pollution endorsement in the mid 1980s; and (ii) underground storage tank leaks mainly from New Jersey homeowners policies. These environmental claims stem primarily from insured exposures in municipal government, small non-manufacturing commercial risks, and homeowners policies.



The total carried net losses and loss expense reserves for these claims were $21.2 million as of December 31, 2017 and $22.7 million as of December 31, 2016. The emergence of these claims occurs over an extended period and is highly unpredictable. For example, within our Standard Commercial Lines book, certain landfill sites are included on the National Priorities List (“NPL”) by the United States Environmental Protection Agency (“USEPA”). Once on the NPL, the USEPA determines an appropriate remediation planThe total recorded net loss and loss expense reserves for these sites. A landfill can remain on the NPL for many years until final approval for the removalclaims were $21.4 million as of the site is granted from the USEPA. The USEPA has the authority to re-open previously closed sites and return them to the NPL. We currently have reserves for seven customers related to four sites on the NPL.

“Asbestos claims” are claims for bodily injury alleged to have occurred from exposure to asbestos-containing products. Our primary exposure arises from insuring various distributors of asbestos-containing products, such as electrical and plumbing materials. At December 31, 2017, asbestos claims constituted 30%2020 and $21.6 million as of our $21.2 million net asbestos and environmental reserves, compared to 29% of our $22.7 million net asbestos and environmental reserves at December 31, 2016.2019.

“Environmental claims” are claims alleging bodily injury or property damage from pollution or other environmental contaminants other than asbestos. These claims include landfillsOur exposure to environmental liability is primarily due to (i) landfill exposures from policies written prior to the absolute pollution endorsement in the mid 1980s; and leaking(ii) residential underground storage tanks. Our landfill exposure lies largely in policies written for municipal governments, in their operation or maintenance of certain public lands. In addition to landfill exposures, in recent years, we have experienced a relatively consistent level of reported losses in the homeowners line of business related to claims for groundwater contamination from leaking underground heating oil storage tankstank leaks, mainly in New Jersey. The landfill claims stem primarily from insured exposures in municipal government, and small non-manufacturing commercial risks. Some of these claims relate to specific landfill sites on the National Priorities List (“NPL”) by the United States Environmental Protection Agency (“USEPA”). We currently have reserves for six policyholders related to three NPL sites. The underground storage tank claims relate largely to our homeowners policies.In 2007, we institutedintroduced a fuel oil system exclusion on our New Jersey homeowners policies that limits ourgreatly limited this exposure from that point forward.

“Asbestos claims” are claims for bodily injury alleged to have occurred from exposure to leaking underground storage tanks for certain customers.products containing asbestos. Our primary exposure arises from policies issued to various distributors of asbestos-containing products, such as electrical and plumbing materials. At that time, existing customers were offered a one-time opportunityDecember 31, 2020, asbestos claims constituted 23% of our $21.4 million net asbestos and environmental reserves, compared to buy back oil tank liability coverage.  The exclusion applies to all new homeowners policies in New Jersey. These customers are eligible for the buy-back option only if the tank meets specific eligibility criteria.23% of our $21.6 million net asbestos and environmental reserves at December 31, 2019.
 
Our asbestos and environmental claims are handled in our centralized and specialized asbestos and environmental claim unit. CaseThat unit establishes case reserves for these exposureson individual claims based upon the facts and circumstances known at a given point in time, which are evaluated on a claim-by-claim basis. The ability to assess potential exposure often improves as a claim develops, including judicial determinations of coverage issues. As a result, reserves are adjusted accordingly.supplemented by bulk IBNR reserves.

Estimating IBNR reserves for asbestos and environmental claims is difficult because of thethese claims have delayed and inconsistent reporting patterns associated with these claims.patterns. In addition, there are significant uncertainties associated with estimating critical reserve assumptions, such as average clean-up costs, third-party costs, potentially responsible party shares, allocation of damages, litigation and coverage costs, and potential state and federal legislative changes. Normal historically-based actuarial approaches cannot be applied to asbestos and environmental claims because past loss history is not indicative of future potential loss emergence. In addition, while certain alternative models can be applied, such models can produce significantly different results with small changes in assumptions. As a result, we do not calculate an asbestos and environmental loss range. Historically, our asbestos and environmental claims have been significantly lower in volume, with less volatility and uncertainty than many of our competitors in the Standard Commercial Lines industry. Prior to the introduction of the absolute pollution exclusion endorsement in the mid-1980's, we were primarily awrote Standard Personal Lines, carrier and therefore do not have broadwhich has limited our exposure to asbestos and environmental claims. Additionally, we are the primary insurance carrier on the majority of these

Other Latent Exposures
We also have other latent and continuous trigger exposures which provides more certainty in our reserve position comparedongoing portfolio. Examples include claims for construction defect and abuse or molestation, for which states have increased and expanded the statute of limitations. We manage our exposure to othersthese liabilities through our underwriting and claims practices and, like asbestos and environmental claims, a dedicated claims unit handles these claims. The impact of social, political, and legal trends on these claims remains highly uncertain, so our loss and loss expense reserves on these claims remain highly uncertain. These exposures remain in the insurance marketplace.

Pensionour ongoing portfolio, and Post-retirement Benefit Plan Actuarial Assumptions
Our pension and post-retirement benefit obligations and related costsas such, are calculated using actuarial methods,reserved in aggregate, with other exposures within the frameworkline of U.S. GAAP. Two key assumptions, the discount rate and the expected return on plan assets, are important elements of expense and/or liability measurement. We evaluate these key assumptions annually. Other assumptions involve demographic factors, such as retirement age and mortality.business reserves.
The discount rate enables us to state expected future cash flows at their present value on the measurement date. The purpose of the discount rate is to determine the interest rates inherent in the price at which pension benefits could be effectively settled. Our discount rate selection is based on high-quality, long-term corporate bonds. A higher discount rate reduces the present value of benefit obligations. Conversely, a lower discount rate increases the present value of benefit obligations. Our discount rate decreased 63 basis points, to 3.78%, as of December 31, 2017 compared to 4.41% as of December 31, 2016. For additional information regarding our discount rate selection, refer to Note 14. “Retirement Plans” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

44
The expected long-term rate of return on the plan assets is determined by considering the current and expected asset allocation, as well as historical and expected returns on each plan asset class. A lower expected rate of return on pension plan assets would increase pension expense. Our long-term expected return on plan assets increased 12 basis points, to 6.36%, as of





December 31, 2017 compared to 6.24% as of December 31, 2016, reflecting a higher allocation to equity securities in the portfolio.

At December 31, 2017, our pension and post-retirement benefit plan obligation was $381.0 million compared to $346.0 million at December 31, 2016. Plan assets were $363.7 million and $316.5 million at December 31, 2017 and December 31, 2016, respectively. Volatility in the marketplace, coupled with changes in the discount rate assumption, could materially impact our pension and post-retirement life valuation in the future. For additional information regarding our pension and post-retirement benefit plan obligations, see Note 14. “Retirement Plans” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

Investment Valuation and OTTIthe Allowance for Credit Losses on AFS Fixed Income Securities

Investment Valuation
The fair value of our investment portfolio is defined under accounting guidance as the exit price or the amount that would be:be (i) received to sell an asset;asset or (ii) paid to transfer a liability in an orderly transaction between market participants. When determining an exit price we must, when available, rely uponon observable market data. The majority of securities in our equity portfolio have readily determinable fair values and are recorded at fair value with changes in unrealized gains or losses recognized through income. Our available-for-sale ("AFS") fixed income securities portfolio is carriedrecorded at fair value, and the related unrealized gains or losses are reflected in stockholders' equity, net of tax. For both our AFS and held-to-maturity ("HTM")fixed income securities portfolios, fair value is a key factor in the evaluationmeasurement of a security(i) losses on securities for OTTI.which we have the intent to sell, and (ii) changes in the allowance for credit losses.


We have categorized our investment portfolio, based on the priority of the inputs to the valuation technique, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1), the next level of priority to observable data from similar securities that have traded in the marketplace, typically using matrix pricing (Level 2), and the lowest priority to unobservable inputs (Level 3).


The fair value of approximately 99%98% of our investment portfolio isinvestments measured at fair value are classified as either Level 1 or Level 2 in the fair value hierarchy. Fair value measurements in Level 1 represent quoted prices in active markets for identical assets. Fair value measurements in Level 2 represent prices determined using observable data from similar securities that have traded in the marketplace, typically using matrix pricing. The fair value of our Level 2 securities are determined by external pricing services.

OTTIAllowance for Credit Losses on AFS Fixed Income Securities
Our investment portfolioWhen fixed income securities are in an unrealized loss position and we do not intend to sell the security, we record an allowance for credit losses for the portion of the unrealized loss due to an expected credit loss. We estimate expected credit losses on these securities by performing a discounted cash flow (“DCF”). The allowance for credit losses is subject to market declines belowthe excess of amortized cost that may be other than temporaryover the greater of (i) our estimate of the present value of expected future cash flows, or (ii) fair value. The allowance for credit losses cannot exceed the unrealized loss and therefore it may resultfluctuate with changes in the recognitionfair value of OTTI losses. the security.

Factors considered in the determination of whether or not a decline is other than temporarythe allowance for credit losses require significant judgment and include, but are not limited to, the financial condition of the issuer, the expected near-term and long-term prospects of the issuer, and our evaluation of the projected cash flow stream from the security. We also consider the need to record losses on securities for which we have the intent to sell that are in an unrealized loss position.

The various COVID-19-related governmental directives impacted the financial markets, which became volatile earlier in the year. This volatility increased gross unrealized losses on our AFS fixed income securities portfolio from $7.7 million at December 31, 2019, to $116.9 million at March 31, 2020. Since the end of the first quarter, the financial markets have improved and gross unrealized losses were reduced to $11.5 million at December 31, 2020. We analyzed these unrealized losses for credit loss in accordance with our existing accounting policy, which includes performing DCF analyses on each security at the lot level and analyzing these DCFs using various economic scenarios. In performing these DCF analyses, we calculate the present value of future cash flows using various models specific to the major security types in our portfolio. These models use security-specific information and forecasted macroeconomic data to determine possible expected credit loss scenarios based on projected changes in the economy. The forecasted economic data incorporated in the models is based on the Federal Reserve Board’s annual supervisory stress test review on certain large banks and financial institutions. We also have the ability to incorporate internally-developed forecast information into the models as we deem appropriate. In developing our best estimate of the allowance for credit losses, we consider our outlook as to the probability of the various scenarios occurring.

Based on these analyses, we recorded an allowance for credit losses of $4.0 million in 2020 on our AFS fixed income portfolio. After considering the allowance for credit losses, the remaining unrealized losses on this portfolio was $11.5 million. We believe that the volatility and increased unrealized loss balance was driven by fluctuating and widening credit spreads tied to financial market uncertainty about the various COVID-19-related governmental directives. If the assumptions used in our DCF analyses or our outlook as to the occurrence probability of our DCF model scenarios were to change, our allowance for credit losses and the resulting credit loss expense could be material to our results of operations.

Reinsurance
Reinsurance recoverables on paid and unpaid loss and loss expense represent estimates of the portion of such liabilities that we will be recoveredrecover from reinsurers. Each reinsurance contract is analyzed to ensure that the transfer ofsufficient risk existsis transferred to properly record the transactions as reinsurance in the Financial Statements. Amounts recovered from reinsurers are recognized as assets at the same timecontemporaneously and in a manner consistent with, the paid and unpaid losses associated with the reinsured policies. An allowance for estimated uncollectiblecredit losses on our reinsurance recoverable balance is recorded based on an evaluation of balances due from reinsurers and other available information. ThisHowever, reinsurers often purchase and rely on their own retrocessional reinsurance programs to manage their capital position and improve their financial strength ratings. Details regarding retrocessional reinsurance programs are not always transparent, which can make it difficult to assess our reinsurers' exposure to counterparty credit risk. The credit quality of our reinsurers is also impacted by other factors, such as their reserve adequacy, investment portfolio, regulatory capital position, catastrophe aggregations, and risk management expertise. In addition, contractual language interpretations and willingness to pay valid claims can impact our allowance for estimated uncollectible reinsurance. Our allowance for estimated uncollectible reinsurance totaled $4.6$1.8 million at December 31, 2017 and $5.52020, a decrease from $4.4 million at December 31, 2016.2019, as we refined our methodology and implemented the new credit loss standard in 2020. We continually monitor developments that may impact recoverability from our reinsurers, andfor which we have available to us contractually providedcontractual remedies if necessary. For further information regarding reinsurance, see the “Reinsurance” section below and Note 8.9. “Reinsurance” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.





Allowance for Credit Losses on Premiums Receivable
We estimate an allowance for credit losses on our outstanding premiums receivable balance at each reporting date. In determining this allowance, we use a method that considers the aging of the receivable based on the effective year of the related policy and our historical credit loss experience. We also contemplate expected macroeconomic conditions over the expected receivables collection period, which is short-term in nature because most balances are collected within two years of policy issuance. We increased our allowance for credit losses to $21.0 million during 2020 from $6.4 million at December 31, 2019, to reflect (i) the higher risk of non-payment due to the significant COVID-19-related decline in economic activity, (ii) the individualized payment flexibility we offered our customers, and (iii) our suspension of the effect of policy cancellations, late payment notices, and late or reinstatement fees. Our last suspensions expired in early August 2020. It could take over a year to realize this collections process, and we expect the actual reserve write-offs to materialize over the course of 2021.

Future COVID-19-related economic instability or governmental directives could ultimately impact our estimates and assumptions for credit losses on premiums receivable. Consequently, a change in our allowance estimate may be material to our results of operations in future periods. For additional details about this estimate, see Note 8. "Allowance for Credit Losses on Premiums Receivable" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

Accrual for Auditable Premium
We estimate auditable premium, which we either bill or return on expired policies based on exposure levels (i.e. payroll or sales), when it is reasonably possible to do so based on historical trends adjusted for the uncertainty of future economic conditions. If we determine it is not reasonably possible to estimate this premium, we do not do so. In the first quarter of 2020, we recorded a $75 million return audit and mid-term endorsement premium accrual in response to the COVID-19 pandemic and the anticipated decline in payroll and sales exposures on the workers compensation and general liability lines of business. During the remainder of the year, we applied premium adjustments for endorsements and audits against our accrual, resulting in a remaining $24.8 million accrual as of December 31, 2020. We currently anticipate the balance of the return audit premiums will occur through the middle of 2021. Since April 2020, through active engagement between our underwriters, distribution partners, and insureds, we have set exposure levels to reflect our best estimate of how the current environment may impact our policies. As a result, we have not accrued for additional or return premium on any policies since that time. Further economic instability and renewed or extended COVID-19-related governmental directives ultimately could impact our estimates and assumptions, and consequently, changes in this liability estimate may be material to the results of operations in future periods. For additional details about this estimate, see Note 9. "Reinsurance" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

2Non-GAAP operating income is a measure that is comparable to net income available to common stockholders with the exclusion of after-tax net realized and unrealized gains and losses on investments, and after-tax debt retirement costs. Non-GAAP operating income is used as an important financial measure by us, analysts, and investors because the realization of investment gains and losses on sales of securities in any given period is largely discretionary as to timing. In addition, net realized and unrealized investment gains and losses on investments that are charged to earnings and the debt retirement costs could distort the analysis of trends.

We delivered strong financial results in 2017 with net income of $168.8 million, up 7% from 2016, and non-GAAP operating income of $184.9 million, up 14% from 2016. WeIn 2020, we generated a 10.4% ROE in 2017 and an 11.4%10.5% non-GAAP operating ROE, which fell slightly below our key measure11% target for the year and our 2019 return of long term financial success, with13.3%. Our 2020 non-GAAP operating ROE was negatively impacted by net unrealized after-tax gains on our fixed income securities portfolio, which increased our GAAP equity and decreased our non-GAAP operating ROE increasing 40by approximately 120 basis points from 11.0%points. Nevertheless, we consider this an impressive result in 2016. Our strong financial results were driven by a record levelthe context of after-tax underwriting income, despite the record level of insured globalCOVID-19, significant catastrophe losses in 2017loss activity, and a relatively weak overall commercial lines pricing environment, and a record level of after-tax net investment income, despite the continuedprolonged low interest rate environment. Our record levelenvironment that has continued to put downward pressure on our investment portfolio returns. The following is a more detailed discussion of after-tax underwriting incomethese items.

COVID-19
A $75 million return audit and mid-term endorsement premium accrual recorded in the first quarter of 2020 to reflect our efforts to: (i) drive renewal pure price increases atestimate of reduced exposures on our March 31 inforce policies due to the account level within our Standard Commercialsignificant economic slowdown and Standard Personal Lines segments as well as our E&S segment; (ii) generate new businessthe anticipated decline in payroll and grow oursales exposures in the workers compensation and general liability lines of business. During the remainder of the year, we recorded $50.2 million of mid-term endorsement and negative audit premium adjustments against this $75 million accrual. As of December 31, 2020, we had a remaining accrual of $24.8 million. Net of reduced losses and commissions, the earned impact of the return audit and mid-term endorsement premium accrual lowered pre-tax underwriting results by $15.3 million, in 2020.

A $19.7 million reduction in net premiums written;written ("NPW") recorded in the second quarter of 2020 to reflect a then voluntary credit to our personal and (iii) improve the underlying profitabilitycommercial automobile customers with in-force policies equivalent to 15% of our book of business through various underwritingtheir April and claims initiatives. Our NPW growth of 6% in 2017 and 8% in 2016 was driven by our strong franchise value with our "ivy league" distribution partners. In addition, for more than eight years our Standard Commercial Lines renewal pure price increases have cumulatively outperformed the Willis Towers Watson Commercial Lines Pricing (or CLIPs) survey by approximately 2,100 basis points, while maintaining high retention rates, which has helped improve underlying results. Additionally, in 2017, we appointed 102 retail agents, which is exclusive of 26 agents that have been appointed in our new states of Arizona and New Hampshire, as we continue to seek ways to increase our market share.

In additionMay premiums due to the cumulative renewal pure price increases we have achieved over the past several years, we have driven underwriting and claims process enhancements, and we have improved our mix of business based on expected future profitability. For example, our workers compensation book of business, which represents approximately 17% of our Standard Commercial Lines business, continues to benefit from the steps we have taken in recent years to increase premium rates on this line, despite the fact that pricing was flat in 2017. Additionally, this line has benefited from: (i) an improved business mix that is shifting towards lower hazard and smaller accounts from higher hazard and larger accounts; (ii) claims initiatives, such as reducing workers compensation medical costs through more favorable PPO contracts and greater PPO penetration; and (iii) lower inflationary trends for this long-tail line. For a full discussionunprecedented nature of the COVID-19-related governmental directives and the associated favorable claims initiatives that we have deployed, refer tofrequency impact. During the “Reserves for Losssecond quarter of 2020, the premium credits were offset by an equal reduction in loss and Loss Expenses” section within Critical Accounting Policiesloss expenses, as claims frequency on our personal and Estimates in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Our commercial and personal automobile lines of business declined due to governmental directive-induced reduced miles driven. As the number of vehicles we insure has not significantly declined, frequencies are returning closer to normal levels as the COVID-19-related governmental directives terminate and there is uncertainty about potential impacts to severities.

A $13.5 million, pre-tax, increase to our allowance for credit losses on premiums receivable reflecting an increase in credit risk due to billing accommodations that we offered our customers, sometimes in collaboration with or at the direction of our regulators. These accommodations included individualized payment flexibility and suspended the effect of policy cancellations, late payment notices, and late or reinstatement fees. The impact of offering billing accommodations while suspending cancellations increased earned but uncollected premiums. The majority of these state regulations have been unprofitableexpired as of the end of 2020; however, our allowance for credit losses on premiums receivable of $21.0 million is expected to cover anticipated write-offs that will occur over the corresponding collections cycle, which could last more than a year.

A $5.0 million, pre-tax, ultimate net loss estimate for losses related to a small portion of our property policies that provide a $25,000 sub-limited coverage for specified extra expenses to clean or disinfect a property when ordered by a Board of Health.

Overall, these four items (i) reduced pre-tax underwriting results by $33.8 million, or $0.44 per diluted common share, (ii) increased the combined ratio by 1.1 points, and (iii) decreased our ROE by 1.1 points.

Offsetting these COVID-19 specific items was a lower level of reported claim frequencies due to the reduced economic activity and other factors. These lower frequencies directly impacted our property lines loss experience. The impact of these lower than expected non-catastrophe property losses (including automobile physical damage losses) resulted in recent yearsan approximate 1.2 point benefit to our combined ratio. We also reduced our 2020 commercial and remain areaspersonal auto casualty loss costs to partially reflect these lower frequencies for these shorter-tail lines of focusbusiness, which benefited the combined ratio by 0.4 points. No other casualty lines were adjusted. These modest adjustments to our casualty loss estimates recognize the ongoing inherent uncertainty presented by COVID-19, including the potential for late reported claims and higher severities. We will continue to monitor these trends as we progress through 2021. After March 2020, due to the impact of COVID-19, we suspended business travel and entertainment in most of our regions. We also deferred some projects and new hires for a period of time. These items, which we expect to revert back to more normal levels later in 2021, benefited our 2020 expense ratio by approximately 0.7 points.

In total, we estimate the impact of the lower non-catastrophe property losses, the reduction in our loss ratio due to lower miles driven, and the benefit to the expense ratio all discussed above, collectively more than offset the negative impact from the COVID-19 specific accruals. We estimate the net benefit to our 2020 combined ratio was approximately 1.2 points.

Catastrophe Losses
We experienced a significant level of catastrophe losses in 2020, driven by industry-wide U.S. catastrophe loss activity that significantly exceeded the 5- and 10-year historical means of approximately 4 points. Catastrophes included hurricanes, with several making landfall, convective storms, hail storms, wildfires, and civil unrest. Our combined ratio in 2020 included 8.0 points of catastrophe losses, which was close to our highest level in over 20 years. The $215.4 million of catastrophe losses in 2020 compared to $81.0 million in 2019 reduced net income by $106.2 million, and ROE by 4.5 points.

Investment Portfolio Returns
After-tax investment income increased 2% in 2020 compared to 2019, driven by higher returns on alternative investments in our other investment portfolio. Returns on these holdings are taking stepsrecorded on a one-quarter lag, and the strong capital market performance in the second and third quarters of 2020 drove the higher returns. These returns, coupled with (i) operating cash flows that were 20% of 2020 NPW and (ii) proceeds from our preferred stock offering, increased invested assets by 12% during 2020. However, the increase in invested assets did not keep pace with the increase in common stockholders' equity. Accordingly, investment leverage declined, as reflected in invested assets per dollar of common stockholders' equity, which ended 2020 at $2.96, down from $3.05 at December 31, 2019. After-tax portfolio yields also were lower than a year ago, at 2.6% for 2020 compared to improve profitability2.9% for 2019, driven by a lower interest rate environment. The reduced investment leverage, coupled with lower portfolio yields, has resulted in these lines of business. In 2017,a lower investment income contribution to ROE, which was 7.8% in 2020 compared to 9.1% in 2019.

Despite the significant economic impacts described above, we recorded unfavorableexperienced favorable prior year casualty reserve development of $85 million in 2020 compared to $61 million in 2019, which is discussed in more detail in the "Insurance Operations" section of "Results of Operations and increases toRelated Information by Segment" below.

In 2020, we generated our currentseventh consecutive year loss costs for these lines. We will continue to seek to actively implement renewal pure price increases in these lines, which have averaged 6.7% in 2017 for commercial auto and 4.1% for personal auto, to improve the level of profitability of these lines of business, which have not met our risk adjusted return expectations in recent years. We have also been managing our commercial auto in-force book of business in targeted industry segments and we have been reducing exposures to higher hazard commercial auto classes to improve the underlying profitability of this business.

Our E&S segment also remains a focus area,double-digit non-GAAP operating ROEs, with a combined ratio10.5% non-GAAP operating ROE. We also grew book value per common share 15% in 2020 compared to 2019, reflecting $4.09 per diluted common share of 103.0% for 2017. We face a competitive environment in this segment,net income available to common stockholders and our pricing and underwriting initiatives aimed at improving profitability have resulted in a decline in new business volume. Our focus in E&S is$2.25 per diluted common share of after-tax net unrealized gains on improving profitability, rather than premium volume or growth, and we expect continued volatility in net premiums written in this segment until the E&S segment meets our risk adjusted return expectations.

After-tax net investment income grew 20% in 2017 and 5% in 2016. The improvements in 2017 and 2016 were driven by a higher fixed income book yield and improved returns on our alternative investments. We have continued to diversify and modestly increase our exposure to risk assets and move towards a long-term target allocation of approximately 10% of total invested assets. Risk assets, which principally include public equities, high-yield fixed income securities portfolio that were partially offset by $0.94 per diluted common share of dividends paid to common stockholders.

On December 2, 2020, we issued $200 million of 4.60% non-cumulative perpetual preferred stock, which marks the first preferred stock offering in our 94-year history and private assets, represented 8%is a demonstration of our total invested assets at December 31, 2017.investors' confidence in our value proposition and our continued success. In conjunction with this offering, our Board of Directors ("Board") authorized a $100 million share repurchase program. We intend to be disciplined and opportunistic with our buyback program, repurchasing shares when we believe returns are attractive over the long-term for our shareholders.


We generated
Outlook
For 2021, we established a non-GAAP operating ROE target of 11.4% in 2017,11%, which is in line with our long-term goal of generating a non-GAAP operating ROE that is 300 basis points in excess of2020 target. We based our weighted average cost of capital. Our long-term financial2021 target for 2017 was 11.5%, based on anour current estimated weighted average cost of capital, the current interest rate environment, and property and casualty insurance market conditions. Our ROE target sets a high bar for our financial performance, challenges us to perform at our best, and aligns our incentive compensation structure with shareholder interests. We enter 2021 in the strongest financial position in our Company's long history, and we are very well positioned to continue delivering growth and profitability.

Looking ahead to 2021, a number of 8.5%. Our non-GAAP operating ROE was 11.0%areas require our continued focus to position us for 2016, compared to our target of 11.7%, which was basedongoing success:

Delivering on our weighted average coststrategy for continued disciplined growth, driven by greater share of capital of 8.7%. Underwriting profitability, coupled with the performance of our investment portfolio, contributed to this achievement.

The deterioration in the loss and loss expense ratio in 2017 was partially offset by improvement in the underwriting expense ratio of 0.9 points in 2017. This improvement was driven by:

A 0.5-point decrease in commissions to our distribution partners in 2017 due to lower supplemental commission expense, as well as lower base commissions that were driven by targeted actions we took in late 2016 on our homeowners book of business;

A 0.4-point decrease in labor expenses as a percentage of premium in 2017, as we recognized productivity gains from the growth of our business; and

A 0.3-point decrease in pension expense in 2017 reflecting expected returns on pension plan assets that have outpaced expenses in the current year periods. For additional information on our pension plan, refer to Note 14. "Retirement Plans" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

Partially offsetting these improvements was an increase of 0.3 points of other expense items.

The 0.8-point increase in the 2016 underwriting expense ratio compared to 2015 was driven by 0.7 points of higher supplemental commissions to our distribution partners as a result of improved underwriting profitability, as well as increased compensation paid to our employees, partially offset by reduced pension costs driven in part by the curtailment of our pension plan in the first quarter of 2016.

Investments Segment
The ROE contribution from investment income has increased in 2017 compared to 2016 reflecting higher yields on our core fixed income portfolio, coupled with a higher asset base driven by cash flows from operations that were 16% of NPW for the year. In addition, our alternative investment portfolio generated $8.3 million in after-tax income in 2017 compared to $2.0 million in 2016.

Net realized gains/losses, which is another component of our investment segments' results, experienced volatility in its contribution to ROE in 2015 through 2017. For qualitative information regarding these fluctuations, which include OTTI charges and investment sales that are largely discretionary as to timing, refer to Note 5. "Investments" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

Other
The reduction to ROE from "other" in the "Reconciliation of ROE to non-GAAP operating ROE" table above is primarily related to share-based compensation expense at the holding company level. This component of ROE improved marginally in 2017, reflecting a 0.3-point benefit from a change in accounting treatment that requires certain share-based compensation tax benefits to be recorded through income beginning in 2017, coupled with a change in our share-based compensation agreements that began with our 2017 awards. We restructured our newly-issued stock compensation awards to be more aligned with grant date fair value expense treatment and lowered the allocation to awards that require fair value adjustments subsequent to grant date. However, the 36% increase in our stock price during 2017 has resulted in fair value adjustments to our outstanding awards that have increased our share-based compensation expense and offset the savings associated with the structural changes.



Outlook
longer term. We continue to execute successfully on several important objectives that have set the table forwork to achieve our performance in 2018, including: (i) achievinglonger-term Standard Commercial Lines 3% market share target in our 27 primary operating states, which represents an additional $3 billion premium opportunity. Our strategy is to appoint distribution partners representing approximately a 25% market share and seeking an average 12% share of wallet, or percentage of these partners' books of business. In addition, we anticipate re-starting our geographic expansion strategy. The five states that we opened during 2017 and 2018, including a new Southwest region, are all performing ahead of expectations. Over the next two years, we plan to open three additional states subject to regulatory approval, Idaho, Vermont, and Alabama, , and we plan to open others in subsequent years. Our long-term goal is to have national capabilities, although we will follow a measured and disciplined approach to identifying and opening new markets.

Continuing to achieve written renewal pure price increases that meet or exceed expected loss trend, while delivering
on our strategy for continued disciplined growth. While we continue to navigate a challenging economic environment,         we are comfortable with the overall price adequacy of 2.9% for full-year 2017 and 2.8% in January 2018; (ii) improving renewal underwriting quality while maintaining strong and stable retention; (iii) targeting underwriting actions in our E&S Lines to improve profitability in this segment; and (iv) achieving strong investment results with after-tax new money rates of 2.1% and strong operating cash flow that was 16% of NPW in 2017. All of these achievements will help drive our future financial performance in 2018 and beyond.

Despite our strong financial performance in 2017 and expectations for 2018, the U.S. property and casualty insurance industry continues to be characterized by an abundance of capital, intense competition and low overall premium growth. According to A.M. Best's "US Property/Casualty: 2018 Review & Preview," for 2018, rate increases are expected to remain in the low single digits for most linesbook of business. A.M. Best is estimating an overall statutory combined ratio for

Delivering a superior omnichannel customer experience by offering value-added technologies and services. We have significantly enhanced our customer experience capabilities over the industry for 2018 of 100.0% and an estimated after-tax return on surplus of 5.8%. In addition, A.M. Best estimates that property and casualty loss and loss adjustment expense reserve adequacy peakedlast several years, ago and reserve adequacy has been declining since.

Our long-term growth plans include: (i) increasing the Standard Commercial Lines market share held by our "ivy league" distribution partners to at least 25%; (ii) increasing our share of the business within these distribution partners, which we refer to as our "share of wallet," to 12%; and (iii) geographic expansion. To date, we write Standard Commercial Lines business in 25 states and the District of Columbia, which at a 3% market share, would create a corporate Standard Commercial Lines profile in excess of $4 billion of net premiums written.

Effective July 1, 2017, we opened Arizona and New Hampshire for Standard Commercial Lines business. We have appointed a total of 26 agents in these states, with appointments in each state controlling in excess of 20% of that state's available Standard Commercial Lines premium. During 2017, we generated $9.1 million of premium volume in these new markets. On January 1, 2018 we opened Standard Commercial Lines business in Colorado, and we expect to open New Mexico and Utah by the end of 2018. We also expect to open Arizona and Utah for Standard Personal Lines business in the future.

Investing in the development and implementation of leading technologies to enhance our underwriting is integral to our overall strategy. The ability to segment our business on a granular basis allows us to present the right price for a given risk. In 2017, we deployed a new underwriting tool that provides real-time insights into how each piece of new business compares with similar accounts already in our portfolio. We believe this tool positions us better to grow the business regardless of overall market dynamics. It also demonstrates our commitment to developing and implementing a best-in-class technology platform that enhances our decision making capabilities.

As an organization, we are making significant investments that are focused on enhancing the overall customer experience in an omni-channel environment. To that end, we have recently deployed a new customer experience desktop to our contact center employees and we are also working closely with our distribution partners to ensure we presentprovide our customers with various digital and self-service offerings. Investing in and building out technologies that improve the customer experience journey remains a seamless experience. We recognizecore focus for us.
Building a culture that our customers' expectations on how they engage with us are rapidly evolvingfosters innovation and we continue to strive towards providing best-in-class customer service in a 24-hour, 365-day environment. Our goals in this area areidea generation that is centered around leveraging technology to improve customer retention rates, which should, over time, enhance the quality of our business.

Our investment portfolio generated after-tax net investment income of $119 million in 2017, which was a 20% increase over 2016. We have generated strong investment returns despite low interest rates, while maintaining a similar level of credit quality and duration risk on the portfolio. Risk assets, which principally include high-yield fixed income securities, equities,values of diversity, equity and inclusion, as we seek to develop a group of specially trained leaders to take our alternative investment portfolio, are up modestly to 8% from 7% last year end. We have been gradually diversifying our portfolio, and will likely continue to modestly increase our risk asset allocation over time up to approximately 10% of our invested assets, depending on market conditions.company into the future.

Our 2018 results will be favorably impacted by Tax Reform, which we expect to lower our effective tax rate by 10 percentage points, to approximately 18% going forward, including 17% from net investment income and approximately 21% for all other items. This effective rate will fluctuate depending on the investment portfolio's allocation to tax-advantaged municipal securities, which will continue to be taxed at 5.25%. We expect this benefit to assist us in achieving our long-term goal of generating non-GAAP operating ROE that is approximately 300 basis points in excess of our weighted average cost of capital over time.



Our achievements in 2017, coupled with the impact of Tax Reform, will help drive our future financial performance in 2018 and beyond.

In January 2018, we experienced an estimated $63 million of insured property losses which were approximately $30 million in excess of our property loss expectations for the month of January. Refer to Note 21. "Subsequent Events" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K for additional information.

For 2018, we expect to generate the following results:2021, our full-year guidance is as follows:


A GAAP combined ratio, excluding catastrophe losses, of approximately 91.0%. This assumes no prior yearprior-year casualty reserve development;

Catastrophe losses of 3.54.0 points;

After-tax net investment income of $144$182 million, which includes $10$16 million of after-tax net investment incomegains from our alternative investments;

An overall effective tax rate of approximately 18%20.5%, which also includes an effective tax rate of 17%19.0% for net investment income inclusive of tax-advantaged municipal securities' tax rate of 5.25%, and approximately 21% for all other items; and

Weighted average shares outstanding of 59.6 million.60.5 million on a diluted basis.


Our weighted average cost of capital has increased from 8.5% in 2017 to 9.0% in 2018, driven principally by a higher estimated cost of equity, and as such our long-term financial target of generating a non-GAAP operating ROE of 300 basis points above our weighted average cost of capital, has increased our financial target to 12.0% for 2018.

Our NPW increased 3% in this segment of our business has reflected:2020 compared to 2019, reflecting (i) overall renewal pure price increases;increases of 4.3%, (ii) increased retention, and (iii) new business growth;of $579.7 million in 2020 compared to $548.7 million in 2019. The net appointment of 42 retail agents, excluding agency consolidations, also contributed to our new business growth. This solid growth in a challenging economic environment reflects the strong relationships we have with our best-in-class distribution partners, our sophisticated underwriting and (iii) stable retention. Quantitative informationpricing tools, and excellent customer servicing capabilities.

The rate of NPW growth in 2020 was negatively impacted by approximately 4 percentage points due to the following:

For qualitative discussions regarding reserve development, refer to the insurance segment sections below.

Underwriting Expenses
Our underwriting expense ratio was 33.8% in 2020, which was flat compared to 2019. The expense ratio included 1.1 points of COVID-19 specific items, which included the $13.5 million addition to our allowance for credit losses on premiums receivable and lower net earned premiums from the audit premium accrual and premium credits. Excluding these COVID-19 specific items, our underlying expense ratio of 32.7% reflected our ongoing expense management initiatives, and about 70 basis points of temporary expense reductions mainly due to the lower travel, and entertainment expenses, and other expenses as a result of COVID-19.

Consistent with higher property losses, as displayedour overall insurance operations, NPW growth in 2020 was negatively impacted by approximately 4 percentage points due to the following:

Our $75 million estimate of audit and endorsement return premium related to the impact of COVID-19 on our workers compensation and general liability lines of business.
A $15.4 million premium credit to our commercial automobile customers related to reduced miles driven and loss frequency due to the COVID-19 pandemic.

The increase in the loss and loss expense ratio in 2017 was partially offset by a 1.2-point decrease in the underwriting expense ratio in 2017 compared to 2016. The expense improvement drivers in this segment of our business are similar to those driving our overall insurance results as described in the financial highlights section above and include:

A 0.3-point decrease in supplemental commissions to our distribution partners;

A 0.4-point decrease in labor expenses reflecting productivity gains from the growth of our business, including our geographic expansion efforts; and

A 0.3-point decrease in pension expense due to the extension of the amortization period over which we are recognizing the net actuarial loss on our pension plan.

There was an increase of 1.0 point in the underwriting expense ratio in 2016 compared to 2015. This increase was primarily attributable to higher supplemental commission expense to our distribution partners of 0.9 points.

In 2020, the prior year reserve development was primarily attributable to favorable reserve development on loss severities in accident years 2017 and prior.

While this line was as follows:

2017:experienced favorable prior year casualty reserve development in 2020, we remain cautious about the inherent uncertainty presented by COVID-19, including the potential for late reported claims and higher severities. Additionally, this line is exposed to other unfavorable trends, including social inflation and state laws enacted that extend the statute of 8.5 pointslimitations or open windows for previously time-barred actions. We will continue to monitor these trends in 2021.

This reduction primarily relates to the past three years, growthimpact of strong renewal pure price increases we have earned in this line of business has reflected:over the last several years and underwriting actions we have taken to improve profitability. Current year loss costs also benefited from decreases in claim frequencies reflecting reduced miles driven related to the COVID-19-related governmental directive.

This line of business remains an area of focus for us and most of the industry. Profitability challenges continue to generate
combined ratios higher than our risk-adjusted targets and the inherent uncertainty COVID-19 presents includes the potential for late reported claims and higher severities. We will continue to (i) actively implement price increases consistent with levels experienced in 2020, and (ii) enhance our underwriting tools to improve the accuracy of our rating information to prevent premium leakage. We also have been actively managing our new and renewal pure price increases; (ii) new business, growth; and (iii) stable retention.we expect our actions will positively impact profitability through business mix improvement.

In addition to the drivers in the table above, the 2020 NPW was impacted by a $28.7 million reduction in audit and mid-term endorsement premiums driven by the COVID-19 pandemic, which is discussed in the "Insurance Operations" section above.

The 3.9-point increase in the combined ratio in 20172020 compared to 20162019 was primarily driven by a 5.4-point increase in the loss and loss expense ratio, which was attributable to the following: (i) an increase in the current year loss reserve estimate of 4.6 points reflecting higher casualty claim frequency; and (ii) unfavorableless favorable prior year casualty reserve development, as follows:

The favorable reserve development for both periods was due to continued favorable medical severity trends impacting accident years 2018 and prior. Due to the length of time that increasedinjured workers can receive medical treatment, decreases in medical inflation can cause favorable loss development across an extended number of accident years.

While reported profitability on this line remains strong due to favorable emergence on prior year reserves, current accident year
margins do not support the continued negative pricing levels being set by the National Council on Compensation
Insurance and independent state rating bureaus. A reduction or reversal in the trend of favorable frequencies and severities has
the potential to significantly increase this line's combined ratio, by 1.8 pointswhich we monitor closely.

NPW growth in this line in 2020 compared to last year. The increase in the loss and loss expense ratio was partially offset by a 1.3-point decrease in the underwriting expense ratio.

The 8.6-point increase in the combined ratio in 2016 compared to 2015 was driven by: (i) unfavorable prior year casualty reserve development that increased the combined ratio by 5.5 points compared to 2015; (ii) an increase in the current year loss reserve estimate of 2.1 points reflecting higher casualty claim frequency; and (iii) higher property losses of 1.0 point.

Prior year casualty reserve development was as follows:

2017: Unfavorable development of 8.1 points, which was driven primarily by increases in accident years 2012 through 2016, due to higher than expected frequency and severity.

2016: Unfavorable development of 6.3 points, which was driven primarily by bodily injury liability for accident years 2014 and 2015. The unfavorable development in accident year 20142019 was driven by higher than expected severity, whereas accident year 2015 was driven by higher than expected frequency and severity.

2015: Unfavorable development of 0.8 points, which was driven by bodily injury liability for accident years 2013 and 2014. This was partially offset by favorable development in accident years 2010 and 2011. The unfavorable development in accident years 2013 and 2014 was driven by severities that were greater than expected.

NPW increases in the last three years were due to strong retention and new business. The NPW increases in 2016 compared to 2015 were also driven by(i) renewal pure price increases.increases, (ii) new business growth, and (iii) increased retention.

The improvement in the combined ratio was attributable to the loss and loss expense ratio, which decreased 0.9 points in 2017 driven by lower current year loss costs, which was partially offset by lower favorable prior year development. Additionally, the expense ratio improved by 1.2-points, consistent with the improvement in overall Standard Commercial Lines discussed above.

The 2016 combined ratio decrease compared to 2015 was due primarily to a favorable prior year casualty development, which for all years is outlined in the table below.

Our commercial property business has experienced profitable results during the three-year period in the table above despite a competitive pricing environment. Although the table below reflects higher severities for our property losses, our results have benefited from generally benign catastrophe loss activity in our geographic footprint. We believe pricing will strengthen as a result of the level of industry-wide catastrophic events.

The prior year development in both 2017 and 2016 primarily related to our personal automobile book of business.

The underwriting expense ratio decreased in 2017 compared to 2016 reflecting: (i) targeted actions taken on our homeowners book of business that drove a 0.7-point decrease in direct commissions for this segment; (ii) a decrease in supplemental commissions to our distribution partners of 0.2 points; and (iii) a reduction in pension expense of 0.3 points.

The loss and loss expense ratio improvement in 2017 compared to 2016 is primarily attributable to a decrease in current year loss costs reflecting our underwriting and claims improvement initiatives, including generating earned rate that is sufficient to outpace loss costs. The 2016 improvement compared to 2015 was primarily due to lower unfavorable prior year casualty reserve development.

Unfavorable prior year casualty reserve development for 2017 was $10 million, driven by increases in claims severities in accident years 2014 and 2015. Unfavorable prior year casualty reserve development for 2016 was $6 million, driven by increases in claims severity in accident year 2014.the bad debt provision during 2020 of 1.5 points.


The underwriting expense ratio improvement in 2017 compared to 2016 was primarily due to a 0.8-point increase in the allocation of corporate services to this segment in 2017. The improvement in the underwriting expense ratio in 2016 compared to 2015 was primarily driven by a 1.6-point reduction year over year from the annual cash incentive plan payment for employees in this segment based on 2015 underwriting results.

Reinsurance
We use reinsurance to protect our capital resources and insure us against losses on property and casualty risks that we underwrite. We use two main reinsurance vehicles: (i) a reinsurance pooling agreement among our Insurance Subsidiaries through which each company agrees to share in premiums and losses based on certain specified percentages; and (ii) reinsurance contracts and arrangements with third parties that cover various policies that we issue to our customers.
57



Reinsurance Pooling Agreement
The primary purposes of the reinsurance pooling agreement among our Insurance Subsidiaries are the following:to:
 
Pool or share proportionately the underwriting profit and loss results of property and casualty insurance underwriting operations through reinsurance;


Prevent any of our Insurance Subsidiaries from suffering undue loss;

Reduce administration expenses; and


Permit all of the Insurance Subsidiaries to obtain a uniform rating from A.M. Best.AM Best Company ("AM Best").


The following illustrates the pooling percentages by Insurance Subsidiary as of December 31, 2017:

Reinsurance Treaties and Arrangements
By entering into reinsurance treaties and arrangements, we are able tocan increase our underwriting capacity, and acceptaccepting larger individual risks and a larger aggregationaggregations of risks without directly increasing our capital or surplus. Our reinsurance program principally consists of traditional reinsurance. Under our reinsurance treaties, the reinsurer generally assumes a portion of the losses we cede to them in exchange for a portion of the premium. Amounts not reinsured below an attachment pointa specified dollar threshold are known as retention. Reinsurance does not legally discharge us from liability under the terms and limits of our policies, but it does make our reinsurer liable to us for the amount of liability we cede to them. In addition, ourOur reinsurers often rely on their own reinsurance programs, or retrocession, as part of managingretrocessions, to manage their exposure to large losses.

"Financial Statements and Supplementary Data." of this Form 10-K.




We have reinsurance contracts that separately cover our property and casualty insurance business. Available reinsurancebusiness that can be segregated into the following key categories:


Property Reinsurance, -which includes our (i) property excess of loss treaties purchased for protection against large individual property losses and our(ii) property catastrophe treaties purchased to provide protection for the overall property portfolio against severe catastrophic events.

Terrorism Reinsurance - in addition to, which provides a federal reinsurance backstop, behind the protection built into our property and casualty reinsurance treaties, terrorism protection is available as a federal backstop related tofor terrorism losses as providedcovered under the Terrorism Risk Insurance Program Reauthorization Act (“TRIPRA”). For further information regarding this legislation,about TRIPRA, see Item 1A. “Risk Factors.” of this Form 10-K.


Flood Reinsurance - as a servicing carrier, for which all of the premiums and losses related to our participation in the WYO Program,(for which we also receive a fee for writing flood business, for which the related premiums and lossesservicing fee) are 100% ceded to the federal government.

In addition to the above categories, we have entered into several reinsurance agreements with Montpelier Re Insurance Ltd., now part of SOMPO Holdings, Inc., as part of the acquisition of MUSIC in December 2011. Together, these agreements provide protection for losses on policies written prior to the acquisition and any development on reserves established by MUSIC as of the date of acquisition. The reinsurance recoverables under these treaties are collateralized.


Property Reinsurance
TheWe renewed the property catastrophe treaty, which covers both our standard market and E&S business, was renewed effective January 2018. An1, 2021. For the main property catastrophe excess of loss treaty program, we maintained our expiring retention. We also purchased an additional $50 million layer was placedin limit at the top of theour program, bringingthereby extending the total program's coverage to $735$785 million in excess of a $40 million. The annual aggregate limit net of our co-participation is approximately $1.1 billion for 2018. million retention.We also renewed the separate catastrophe treaty of $35 million in excess of $5 million that covers events outside of our historical2015 22-state footprint and supports (i) our standard lines footprint, in support of our growing E&S property book and geographic expansion into Arizona, New Hampshire, Colorado, Utah, and Colorado.New Mexico and (ii) our growing E&S property book. Both treaties were renewed on substantially the same terms as the expiring treaties except (i) restrictions in coverage were imposed related to the systemic perils of communicable disease and (ii) first party cybersecurity coverage, an expected result consistent with current market conditions. Consequently, the property catastrophe program now excludes coverage for communicable disease, but it retains reduced reinsurance coverage for cybersecurity risks. Despite these new limitations, coverage for traditionally covered property perils was maintained. Overall catastrophe ceded premium for 20182021 increased due to some hardening ofthree factors: (i) increases in underlying property exposures in line with our growing overall portfolio; (ii) the reinsurance market and the purchase of thenew additional $50 million layer. Onof coverage purchased at the top of our treaty to maintain stability in our net risk profile; and (iii) a reinsurance environment characterized by higher risk-adjusted pricing, more rigorous underwriting, and reduced capacity. These dynamics were fueled by such factors as the uncertainty surrounding the impact of COVID-19, lower interest rates, and elevated catastrophe loss activity. However, on a risk-adjusted basis, the expiring layers saw a very modest increaserate increases, in price.line with market conditions for loss-free accounts sharing our geographic footprint.


As our need for catastrophe reinsurance increases, weWe seek ways to minimize credit risk inherent in awithin our reinsurance transactionprogram by dealingtransacting with highly-rated reinsurance partners and, where feasible, purchasing collateralized reinsurance products, particularly for high severity,high-severity, low-probability events. The current reinsurance program includes $224$281 million in collateralized limit, primarily in the top layerslayer of the catastrophe program.


We continue to assess our property catastrophe exposure aggregations, modeled results, and effects of premium growth on our property portfolio, andportfolio. We strive to managebalance our exposure to individual large events balanced against the cost of reinsurance protections.

We usereview our exposure to hurricane risk by examining the results of the Risk Management Solutionsa third-party vendor model and AIR Worldwide models in our review of exposure to hurricane risk. Each of these third party vendors provide two views of the modeled results as follows: (i)proprietary analysis. The third-party vendor model provides a long-term view that closely relates modeled event frequency to historical hurricane activity;activity and (ii) a medium-term view that adjusts historical frequenciesis adjusted to reflect expectationsassumptions for certain non-modeled costs, such as the impact of hurricane activity in the near future.loss expenses, residual market assessments, and automobile-related losses. We believe that modeled estimates provide a range of potential outcomes, and we review multiple estimates for purposes of understandingto understand our catastrophic risk.

Montpelier Re Quota Share and Loss Development Cover
(covers E&S Lines)
As part of the acquisition of MUSIC we entered into several reinsurance agreements that together provide protection for losses on policies written prior to the acquisition and any development on reserves established by MUSIC as of the date of acquisition.  The reinsurance recoverables under these treaties are 100% collateralized. Montpelier Re was acquired by Endurance Specialty on December 29, 2015. On March 28, 2017, Endurance Specialty was acquired by SOMPO Holdings, Inc.Provides full terrorism coverage including NBCR.


We have other reinsurance treaties, that we do not consider core to our reinsurance program, such as our (i) Surety and Fidelity Excess of Loss Reinsurance Treaty, (ii) National Workers Compensation Reinsurance Pool Quota Share, which covers business assumed from the involuntary workers compensation pool, our(iii) Endurance Specialty Quota share and Loss Development Cover, which provides protection for losses on policies written prior to the acquisition and any development on reserves established by MUSIC as of the date of acquisition, (iv) Equipment Breakdown Coverage Reinsurance Treaty, (v) Multi-line Quota Share, which covers additional personal lines coverages, and our Data Compromise Reinsurance Treaty.(vi) Cyber Liability Quota Share.


We regularly reevaluateevaluate our overall reinsurance program, and we try to develop effective ways to manage the transfer of risk. OurWe base our analysis is based on a comprehensive process that includes periodic analysis of modeling results and review of our own loss experience, aggregation of exposures, exposure growth, diversification of risks, limits written, projected reinsurance costs, reinsurer financial strength, of reinsurers, and projected impact on earnings, equity, and statutory surplus. We strive to balance sometimes opposing considerations of reinsurer credit quality, price, terms, and our appetite for retainingto retain a certain level of risk.


Investments Segment
The primary objective of the investment portfolio is to maximize after-tax net investment income and the overall total return of the portfolio, while maintaining a high credit quality core fixed income securities portfolio and managing our duration risk profile. Our investment philosophy includes certain return and risk objectives for the fixed income, equity, and other investment portfolios. After-tax yield and income generation are key drivers to our investment strategy, which we believe will be obtained through more active management of the portfolio.

The increase in our investment portfolio at December 31, 2017 compared with year-end 2016 was primarily driven by operating cash flow of $370.7 million, $51.1 million of which was used to fund shareholder dividends and capital expenditures in the aggregate. The $59.9 million change in unrealized gains was comprised of $46.8 million from our fixed income securities and $13.0 million from our equity portfolio.



We seek to structure our portfolio conservatively with a focus on: (i) asset diversification; (ii) investment quality; (iii) liquidity, particularly to meet the cash obligations of our insurance operations; (iv) consideration of taxes; and (v) preservation of capital. We have a high quality and liquid investment portfolio. The breakdown of our investment portfolio is as follows:

The currenteffective duration of the fixed income securities portfolio is within our historical range, and is monitored and managed to maximize yield while managing interest rate risk at an acceptable level. We maintain a well-diversified portfolio across sectors, with credit quality and maturities that affords usprovide ample liquidity. Every purchase or sale isPurchases and sales are made with the intent of maximizing risk-adjusted investment returns in the current market environment while balancing capital preservation. Over time, we may seek to increase or decrease the duration and overall credit quality of the portfolio based on market conditions.


Our fixed income securities portfolio maintainedand short-term investment portfolios represented 92% of our invested assets at December 31, 2020, and 96% of our invested assets at December 31, 2019. These portfolios had a weighted average credit rating of AA- ” as of both dates, with investment grade holdings representing 96% of these portfolios at December 31, 2020 and 97% as of December 31, 20172019.

We have also been managing the portfolio's exposure to floating rate securities, withinwhich reset principally to 90-day LIBOR.

Given the current environment, we continue to reinvest proceeds from the non-sale disposal activity primarily related to "AAA" rated agency-backed RMBS into other high quality, at both December 31, 2017but non-AAA rated fixed income sectors, as we find the risk adjusted returns more attractive. Over the coming quarters, we expect the average credit rating will decrease to "A+" from "AA-" and December 31, 2016. remain there for the foreseeable future; however, we do not anticipate a material shift in the overall risk/return characteristics of our fixed income securities portfolio.

Net investmentIncome on our fixed income before tax increased $31.1 millionportfolio was flat in 20172020 compared to 2016, driven by higher yields on our core fixed income securities portfolio, coupled with a higher asset base from2019, as strong operating cash flows thatconstituting 20% of NPW, were 16% of net premiums written. In addition,offset by lower yields on this portfolio, as reflected in the table above. Income from alternative investments in our alternative income portfolio generated higher returns this year as compared to last.

The $9.4 million increase in net investment income before tax in 2016, compared to 2015, was primarily attributable to increases in fixed income securities of $6.1 million and in other investment income of $4.8 million. Returns on fixed income securities increased due to a higher asset base, with a modest increase to taxable asset classes, while improved returns on our energy-related and private equity limited partnershipsportfolio drove the increase in investment income earned in 2020 compared to 2019. Results on these holdings are recorded on a one-quarter lag, and the strong capital market performance in the second and third quarters of 2020, which followed the significant COVID-19-related volatility in the first quarter of 2020, drove this portfolio's higher returns during the year. Additionally, there was a year-over-year decrease in income on our other investment portfolio.short-term investments.


The effective tax rate on our investment portfolio applicable to net investment income has increased approximately 200 basis points per year in the three-year period presented above. This has been driven by a modest increase to taxable asset classes recently coupled with higher returns on our alternative investment portfolio, which is taxed at 35%. As a result of Tax Reform, we anticipate a reduction in the effective rate on net investment income to approximately 17%, inclusive of tax-advantaged municipal securities' tax rate of 5.25% and approximately 21% for all other items, beginning with the 2018 tax year, although the actual effective tax rate will be impacted by our allocation to tax-advantaged municipal securities. See the "Federal Income Taxes" discussion below for additional information regarding the impact of this legislation.

As a result of a change in accounting guidance that became effective on January 1, 2018, realized gains and losses now include the change in market value of our equity securities, which are now recognized in earnings, rather than in accumulated other comprehensive income (loss).

On December 22, 2017, Tax Reform was signed into law, which among other provisions, will reduce our statutory corporate tax rate from 35% to 21% beginning with our 2018 tax year. We revalued our deferred tax inventory as of December 31, 2017 in consideration of this reduction, which resulted in a $20.2 million charge to federal income tax expense as our net deferred tax assets have become less valuable given the decrease in the tax rate. Excluding the impact of this charge, ourThe effective tax rate for 2017 was 27.8%, which is consistent with the other years presented in the table above. In general, our effective tax rateabove differs from the statutory tax rate of 35% primarily because21% principally due to: (i) the benefit of tax-advantaged interest and dividend income. The contributionincome; and (ii) the impact of this tax-advantaged income to overall pre-tax income remained relatively stable in 2015 through 2016 and, as a result, there is not a significant variance inexcess tax benefits on our overall effective tax rate during these periods.stock-based compensation awards,

partially offset by certain disallowances of executive compensation.
As a result of Tax Reform, we anticipate a reduction in our effective rate to approximately 18% going forward, including 17% for net investment income and approximately 21% for all other items. Included in the investment effective tax rate is the tax-advantaged municipal securities' tax rate of 5.25% and 13.125% for dividends on U.S. public equity securities.

Financial Condition, Liquidity, and Capital Resources
Capital resources and liquidity reflect our ability to generate cash flows from business operations, borrow funds at competitive rates, and raise new capital to meet operating and growth needs. We actively managed capital resources and liquidity in 2020, as we increased liquidity early in the year out of an abundance of caution at the onset of the COVID-19 pandemic, repaid those borrowings by year-end, and issued our first preferred stock offering during the fourth quarter of 2020. These activities will be further discussed in the "Liquidity" section below.

Liquidity
We manage liquidity with a focusby focusing on generating sufficient cash flows to meet the short-term and long-term cash requirements of our business operations. Our cashWe also adjust our liquidity in light of economic or market conditions, as discussed further below.

Capital Market Activities
In the fourth quarter of 2020, we enhanced our capital structure flexibility at the Parent by issuing $200 million of 4.60% non-cumulative perpetual preferred stock. Net proceeds after issuance costs were approximately $195 million. The Parent is using these proceeds for general corporate purposes, which may include the repurchase of common stock under a $100 million share repurchase program authorized by our Board in conjunction with the preferred stock offering. No shares were repurchased under this authorization in the fourth quarter of 2020. For additional information on the preferred stock transaction, refer to Note 17. “Preferred Stock” in Item 8. “Financial Statements and short-term investment positionSupplementary Data.” of $166 million at December 31, 2017 was comprisedthis Form 10-K. The Parent had no other private or public issuances of $25 million at Selective Insurance Group, Inc. (the “Parent”) and $141 millionstock or debt instruments during 2020.

Short-term Borrowings
We significantly increased liquidity at the Insurance Subsidiaries. Short-term investments are generally maintainedSubsidiaries and the Parent during the first quarter of 2020 amid the COVID-19 pandemic, which was followed by a period of extreme volatility and uncertainty in "AAA" rated money market funds approvedthe financial markets. In the aggregate, we borrowed $302 million from the FHLBNY, the FHLBI, and our Parent’s line of credit agreement out of an abundance of caution to reduce the likelihood of becoming a forced seller of invested assets to fund operations if there were a significant slowdown in premium payments as a result of the COVID-19 pandemic. We felt this was prudent given our focus on small-to-medium size business and our geographic footprint as we expected that some customers may have significant cash flow disruptions due to the COVID-19-related governmental orders and the economic slowdown. Furthermore, the ultimate viability of some of our commercial customers' businesses depend, in part, on the depth and duration of the economic slowdown, their participation in any federal fiscal stimulus packages, and whether their business is considered essential or non-essential. We routinely monitor our cash positions daily as part of our liquidity management process, and during 2020, we did not experience any material change in our daily cash collections despite the impact of the pandemic. Considering this, we repaid all of our short-term borrowings by the National Association of Insurance Commissioners ("NAIC"). The Parent maintains an investment portfolio containing high-quality, highly-liquid government and corporate fixed income securities. This portfolio amounted to $90 million at December 31, 2017, compared to $74 million at December 31, 2016. In total, we had $114 million2020. For further information regarding these borrowings, see Note 11. "Indebtedness" in Item 8. "Financial Statements and Supplementary Data." of cash and investments at the Parent at December 31, 2017 compared to $92 million at December 31, 2016. We expect to continue to increase the level of cash and invested assets at the Parent over time, although there will be fluctuations in these cash and invested asset balances, based on factors including the amount and availability of dividends from our Insurance Subsidiaries, investment income, expenses and other needs of the Parent. Our target is to increase the cash and liquidity at the Parent to two years of its expected annual needs.this Form 10-K.

Sources of Liquidity
Sources of cash for the Parent historically have historically consisted of dividends from the Insurance Subsidiaries, the investment portfolio discussed above,held at the Parent, borrowings under third-party lines of credit, and loan agreements with certain Insurance Subsidiaries, and the issuance of stockequity and debt securities. We continue to monitor these sources, giving consideration to our long-term liquidity and capital preservation strategies.


The Parent’s investment portfolio provides liquidity primarily through (i) short-term investments generally maintained in “AAA” rated money market funds approved by the National Association of Insurance Commissioners, (ii) high-quality, highly-liquid government and corporate fixed income securities, (iii) equity securities, and (iii) a cash balance. In the aggregate, Parent cash and total investments amounted to $490 million at December 31, 2020, and $278 million at December 31, 2019. The increase in 2020 compared to 2019 was primarily due to net proceeds from our preferred stock offering.

The Parent's liquidity may fluctuate based on various factors, including the amount and availability of dividends from our Insurance Subsidiaries, investment income, expenses, other Parent cash needs, such as dividends payable to shareholders, and asset allocation investment decisions. Our target for the Parent is to maintain liquidity matching at least twice its expected annual needs, which is currently estimated to be approximately $180 million.

Insurance Subsidiary Dividends
The Insurance Subsidiaries paid $80 million in dividends to the Parent in 2017. As of December 31, 2017, our allowable ordinary maximum dividend is $211 million for 2018.



Any dividends to the Parent are subject to the approval and/or review of the insurance regulators in the respective Insurance Subsidiaries' domiciliary states and are generally payable only from earned surplus as reported in the statutory annual statements of those subsidiaries as of the preceding December 31. Although past dividends have historically been met with regulatory approval, there is no assurance that future dividends that may be declared will be approved. For additional information regarding dividend restrictions, refer to Note 19. “Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds” in Item 8. “Financial Statements and Supplementary Data.” of this Form
10-K.

The Insurance Subsidiaries generate liquidity through insurance float, which is created by collecting premiums and earning investment income before lossesclaims are paid. The period of the float can extend over many years. Our investment portfolio consists of maturity dates that continually provide a source of cash flow for claims payments in the ordinary course of business. The effective duration of the fixed income securities portfolio, as well as the liabilities of the Insurance Subsidiaries, was 3.8 years as of December 31, 2017. As protection for the capital resources at the Insurance Subsidiaries, we purchase reinsurance coverage for any significantly large claims or catastrophes that may occur duringoccur.

The Insurance Subsidiaries paid $105 million in dividends to the year.Parent in 2020. As of December 31, 2020, our allowable ordinary maximum dividend is $241 million for 2021. Any Insurance Subsidiary dividends to the Parent are (i) subject to the approval and/or review of its domiciliary state insurance regulator and (ii) generally are payable only from earned surplus reported in its statutory annual statements as of the preceding December 31. Although insurance regulators have approved past dividends historically, there is no assurance that they will approve future dividends that may be declared.


New Jersey corporate law also limits the maximum amount of dividends the Parent can pay our shareholders if either (i) the Parent would be unable to pay its debts as they became due in the usual course of business or (ii) the Parent’s total assets would be less than its total liabilities. The Parent’s ability to pay dividends to shareholders is also impacted by (i) covenants in its credit agreement (discussed below under "Line of Credit") that obligate it, among other things, to maintain a minimum consolidated net worth and a maximum ratio of consolidated debt to total capitalization, and (ii) the terms of our preferred stock that prohibit dividends to be declared or paid on our common stock if dividends are not declared and paid, or made payable, on all outstanding preferred stock for the latest completed dividend period.

For additional information regarding dividend restrictions and financial covenants, where applicable, see Note 11. “Indebtedness,” Note 17. “Preferred Stock” and Note 22. “Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds” in Item 8. “Financial Statements and Supplementary Data.” of this Form

Short-term Borrowings
There were no balances outstanding under the Line of Credit at December 31, 2017 or at any time during 2017. During 2017, SICA borrowed an aggregate of $84 million from the FHLBNY, which was subject to the borrowing limitations outlined above. This amount has already matured and has been paid.

For additional information regarding other borrowings, see Note 10. "Indebtedness" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

Capital Market Activities
The Parent had no private or public issuances of stock or debt instruments during 2017.


Uses of Liquidity
The Parent's liquidity generated from the sources discussed above is used, among other things, to pay dividends to our shareholders. Dividends on shares of the Parent's common and preferred stock are declared and paid at the discretion of the Board of Directors based on our operating results, financial condition, capital requirements, contractual restrictions, and other relevant factors. In October 2017,2020, our Board of Directors approved ana 9% increase in the quarterly cash dividend, to $0.18$0.25 from $0.16$0.23 per share.

Our ability to meet our interest and principal repayment obligations on our debt, as well as our ability to continue to pay dividends to our stockholders, is dependent on (i) liquidity at the Parent, coupled with(ii) the ability of the Insurance Subsidiaries to pay dividends, if necessary, and/or (iii) the availability of other sources of liquidity to the Parent. Our next twoThe Parent has the following upcoming principal repayments, each in the amount of $25payments due:

$25 million are due in 2021, with the next following principal payment due into FHLBNY on July 21, 2021;
$25 million to FHLBNY on August 16, 2021; and
$60 million to FHLBI on December 16, 2026. We have $185 million of Senior Notes due February 9, 2043 that became callable on February 8, 2018. We may elect to call these Senior Notes, in whole or in part, at any time on or after February 8, 2018. If we were to call and redeem these Senior Notes we would write-off the associated unamortized debt issuance costs. The balance of the unamortized debt issuance costs associated with our $185 million of Senior Notes was $4.6 million at December 31, 2017.


Restrictions on the ability of the Insurance Subsidiaries to declare and pay dividends, without alternative liquidity options, could materially affect our ability to service debt and pay dividends on common and preferred stock.


Capital Resources
Capital resources provide protection for policyholders,ensure we can pay policyholder claims, furnish the financial strength to support the business of underwriting insurance risks, and facilitate continued business growth. At December 31, 2017,2020, we had GAAP stockholders’ equity of $2.7 billion and statutory surplus of $1.7$2.1 billion. With total debt of $439$550.7 million at December 31, 2020, our debt-to-capital ratio was approximately 20%16.7%. For additional information on our statutory surplus, see Note 22. "Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.
 
Our cash requirements include, but are not limited to,without limitation, principal and interest payments on various notes payable, dividends to stockholders, payment of claims, payment of commitments under limited partnership agreements, and capital expenditures, as well asand other operating expenses, which includeincluding commissions to our distribution partners, labor costs, premium taxes, general and administrative expenses, and income taxes. For further details regarding our cash requirements, refer to the section below entitled, “Contractual Obligations, Contingent Liabilities, and Commitments.”


We continually monitor our cash requirements and the amount of capital resources that we maintain at the holding company and operating subsidiary levels. As part of our long-term capital strategy, we strive to maintain capital metrics relative to the macroeconomic environment, that support our targeted financial strength.strength relative to the macroeconomic environment. Based on our analysis and market conditions, we may take a variety of actions, including, but not limited to,without limitation, contributing capital to the Insurance Subsidiaries, in our insurance


operations, issuing additional debt and/or equity securities, repurchasing existing debt, repurchasing shares of the Parent’s common stock, and increasing stockholders’ dividends.

Our capital management strategy is intended to protect the interests of the policyholders of the Insurance Subsidiaries and our stockholders, while enhancing our financial strength and underwriting capacity. We have an attractive book of business and
solid capital base, positioning us well to take advantage of market opportunities that may arise.
 
Book value per share increased to $29.28$42.38 as of December 31, 2017,2020, from $26.42$36.91 as of December 31, 2016,2019, primarily due to $2.84$4.09 in net income per diluted common share and a $0.66 per share increase$2.25 in unrealized gains related toon our investment portfolio. These increases werefixed income securities portfolio, which was partially offset by $0.66 paid$0.94 in dividends per share to our common shareholders.


Off-Balance Sheet Arrangements
At December 31, 20172020 and December 31, 2016,2019, we did not have anyhad no material relationships with unconsolidated entities or financial partnerships, such entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitatingto facilitate off-balance sheet arrangements or for other contractually narrow or limited purposes. As such,Consequently, we are not exposed to any material financing, liquidity, market, or credit risk that could arise if we had engaged in such relationships.related to off-balance sheet arrangements.


Contractual Obligations, Contingent Liabilities, and Commitments
Our contractual obligations include required payments under capitalfinance and operating leases, debt obligations, and reserves for loss and loss expenses. As discussed in the “Reserves“Reserve for Loss and Loss Expense” section in the "Critical Accounting Policies and Estimates" section of this MD&A and in Note 2. "Summary of Significant Accounting Policies" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K, we maintain case reserves and estimates of reserves for loss and loss expense IBNR in accordanceconsistent with industry practice. Using generally accepted actuarial reserving techniques, we project our estimate of ultimate loss and loss expense at each reporting date.
 
Given that the lossesloss and loss expense reserves are estimates, as described in detail under the “Critical Accounting Policies and Estimates” section of this MD&A and in Note 2. "Summary of Significant Accounting Policies" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K, the payment of actual loss and loss expense is generally not fixed as to amount or timing. Due to this uncertainty, financial accounting standards prohibit us from discounting these reserves to their present value. Additionally, estimated losses as of the financial statement date do not consider the impact of estimated losses
66



from future business. Therefore, the projected settlement of the reserves for net loss and loss expense will differ, perhaps significantly, from actual future payments.
 
The projected paid amounts by year in the table below by year are estimates based on past experience, adjusted for the effects of current developments and anticipated trends, and include considerable judgment. There is no precise method for evaluating the impact of any specific factor on the projected timing of when loss and loss expense reserves will be paid and as a result,reserve payments, so the timing and amounts of the actual payments will be affected by many factors. Care must be taken to avoid misinterpretation by those unfamiliar with this information or familiar with other data commonly reported by the insurance industry.

Ratings
We are rated by major rating agencies that issue opinions on our financial strength, operating performance, strategic position, and ability to meet policyholder obligations. We believe that our ability to write insurance business is most influenced by our rating from A.M. Best. In the third quarter of 2017, A.M. Best reaffirmed our rating of "A (Excellent)," their third highest of 13 financial strength ratings with a "stable" outlook. The rating reflects A.M. Best's view that we have an excellent level of risk-adjusted capitalization, strong operating performance, and high policy retention across our standard lines of business. We have been rated "A" or higher by A.M. Best for the past 87 years. A downgrade from A.M. Best to a rating below “A-” is an event of default under our Line of Credit and could affect our ability to write new business with customers and/or distribution partners, some of whom are required (under various third-party agreements) to maintain insurance with a carrier that maintains a specified A.M. Best minimum rating.

Ratings by other major rating agencies are as follows:

Fitch Ratings ("Fitch") - Our "A+" Rating was reaffirmed in the second quarter of 2017 with a "stable" outlook by Fitch. In taking this action, Fitch cited our strong financial performance and capitalization with growth in stockholders' equity, as well as a strong competitive position and diversified underwriting.

S&P Global Ratings ("S&P") - Our "A" rating was reaffirmed in the fourth quarter of 2017 with a "stable" outlook by S&P. In taking this action, S&P cited our strong business risk profile and strong financial risk profile, built on our strong competitive position and very strong capital and earnings. In addition, our stable outlook reflects S&P's expectation that we will sustain our strong competitive position and operating performance.

Moody's Investor Service ("Moody's") - Our "A2" financial strength rating with a "stable" outlook was reaffirmed in the second quarter of 2017 by Moody's. In taking this action, Moody's cited our solid regional franchise with established independent agency support, solid risk adjusted capitalization, strong invested asset quality, and good underwriting profitability.

Our S&P, Moody's, and Fitch financial strength and associated credit ratings affect our ability to access capital markets.  The interest rate on our Line of Credit varies and is based on, among other factors, the Parent's debt ratings. There can be no assurance that our ratings will continue for any given period or that they will not be changed.  It is possible that positive or negative ratings actions by one or more of the rating agencies may occur in the future.

We manage our investment portfolio to mitigate risks associated with various financial market scenarios. We, however, will however, takeassume prudent risk to enhance our overall long-term results while managing a conservative, well-diversified investment portfolio to support our underwriting activities.



Interest Rate Risk


Investment Portfolio
We invest in interest rate-sensitive securities, mainly fixed income securities. Our fixed income securities portfolio is comprised of primarily investment grade (investments receiving S&P or an equivalent rating of BBB-BBB+ or above) corporate securities, U.S. government and agency securities, municipal obligations, CLOcollateralized loan obligations ("CLO") and other ABS,asset-backed securities ("ABS"), and MBS.mortgage-backed securities ("MBS"). As of December 31, 2020, approximately 13% of our fixed income securities portfolio was comprised of floating rate securities where the base rate is primarily tied to the U.S. dollar-denominated London Interbank Offered Rate ("LIBOR"). Our strategy to manage interest rate risk is to purchase intermediate-term fixed income investments that are attractively priced in relation to perceived credit risks.
 
Our exposure to interest rate risk relates primarily to the market price and cash flow variability associated with changes in interest rates. As our fixed income securities portfolio contains interest rate-sensitive instruments, it may be adversely affected by changes in interest rates resulting from governmental monetary policies, domestic and international economic and political conditions, and other factors beyond our control. Recent economic data points to increased U.S. and global economic growth, continued low levels of unemployment and signs of rising wages, which compounded with the potential for the pro-growth benefits of Tax Reform and the potential for higher Federal budget deficits, has recently led to rising U.S. interest rates. AAll else being equal, a rise in interest rates will decrease the fair value of our existing fixed income investments, and a decline in interest rates will result in an increase in the fair value of our existing fixed income investments. However, new and reinvested money used to purchase fixed income securities would benefit from rising interest rates and would be negatively impacted by falling interest rates.


We seek to mitigate our interest rate risk associated with holding fixed income investments by monitoring and maintainingmanaging the effective duration of our portfolio with a view toward achieving an adequate after-tax return without subjecting the portfolio to an unreasonable level of interest rate risk. The effective duration of the fixed income securities portfolio at December 31, 2017 and December 31, 2016 was 3.8 years. The current duration is within our historical range, and is monitored and managed to maximize yield while managing interest rate risk at an acceptable level. The effective duration of the fixed income securities portfolio, including short term investments, at December 31, 2020, was 3.8 years, which is within our historical range. The Insurance Subsidiaries’ liability duration iswas approximately 3.8 years.3.7 years at December 31, 2020.
 
We use an interest rate sensitivity analysis to measure the potential loss or gain in future earnings, fair values, or cash flows of market sensitive fixed income securities. The sensitivity analysis hypothetically assumes an instant parallel 200 basis point shift in interest rates up and down in 100 basis point increments from the date of the Financial Statements. We use fair values to measure the potential loss. This analysis is not intended to provide a precise forecast of the effect of changes in market interest rates and equity prices on our income or stockholders’ equity. Further, theThese calculations also do not take into accountconsider (i) any actions we may take in response to market fluctuations and do not take into account(ii) changes to credit spreads, liquidity spreads, and other risk factors whichthat may also impact the value of the fixed income securities portfolio.

Pension and Post-Retirement Benefit Plan Obligation
Our pension and post-retirement benefit obligations and related costs are calculated using actuarial methods within the framework of U.S. GAAP. The discount rate assumption is an important element of expense and liability measurement. Changes in the discount rate assumption could materially impact our pension and post-retirement life valuation in the future. For additional information regarding our discount rate selection, refer to Note 14. "Retirement Plans" in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.




Credit Risk
Our most significant credit risk is within our fixed income securitysecurities portfolio, which had an overall credit quality of “AA-” as of both December 31, 20172020, and December 31, 2016.2019. Exposure to non-investment grade bonds represented approximately 3%5% of the total fixed income securities portfolio at both December 31, 20172020, and 2016.4% at December 31, 2019.


The following table summarizesWe actively monitored and managed the fair value, carry value, net unrealized/unrecognized gain (loss) balances,credit risk exposure in our portfolio associated with the impact of the COVID-19 pandemic and related economic conditions during 2020. We also managed the portfolio's exposure to floating rate securities, which reset principally to 90-day LIBOR. Given the reduction in the valuation of U.S. public equities and the weightedsignificant widening of high yield credit spreads earlier in the year, we modestly increased our allocation to risk assets during 2020 as we identified attractive investment opportunities. Despite the strong performance of our portfolio, the average after-tax new money yield on fixed income security purchases continued to decline as U.S. Treasury rates remained low and credit spreads continued to tighten throughout the year. Given the current environment, we continue to reinvest proceeds from the non-sale disposal activity, primarily related to "AAA" rated agency-backed residential mortgage-backed securities ("RMBS"), into other high

quality, but "non-AAA" rated fixed income sectors, as we find the risk adjusted returns more attractive. Over the coming quarters, we expect the average credit qualitiesrating will decrease to "A+" from "AA-" and remain there for the foreseeable future; however, we do not anticipate a material shift in the overall risk/return characteristics of our fixed income securities portfolio.

1Of the $42.5$39.5 million in state and local Texas general obligation bonds, $23.9$19 million represents investments in Texas Permanent School Fund bonds, which are considered to have lower risk as a result of the bond guarantee programs that support these bonds.




Special revenue fixed income securities of municipalities (referred to as “special revenue bonds”) represent 13% of our total invested assets at December 31, 2020. These securities generally do not have the “full faith and credit” backing of the municipal or state governments, as do general obligation bonds, but special revenue bonds have a dedicated revenue stream for repayment. For our special revenue bonds, 81%67% of the dedicated revenue stream is comprised of the following: (i) essential services (46%(53%), which is comprised of transportation, water and sewer, and electric; and (ii) education (11%(14%), which includes school districts and higher education, including state-wide university systems; and (iii) special tax (24%), which are backed by a dedicated lien on a tax or other revenue repayment source.systems. As such, we believe our special revenue bond portfolio is appropriate for the current environment.
 
Corporate Securities
Our corporate securities represented 31% of our invested assets at December 31, 2020. For investment-grade corporate bonds, we address the risk of an individual issuers'issuer's default by maintaining a diverse portfolio of holdings. The primary risk related to non-investment grade corporate bonds is credit risk. A weak financial profile can lead to rating downgrades from the credit rating agencies,downgrades, which can put further downward pressure on bond prices. Valuations on these bonds are related more directly to underlying operating performance than to general interest rates. Our holdings of non-investment grade corporate bonds, which typically exhibit weaker credit profiles and are subject to more risk of credit loss, represent less than 3% of our overall investment portfolio.

CLO and Other ABS Portfolio
For CLO and other ABS,The following table provides the primary risk is credit risk. We manage this risk by evaluating a number of factors, including the structuring of the deal, the credit quality of underlying loans or assets, thesector composition of the underlyingthis portfolio and the track record and capabilities of the portfolio manager. Key performance metrics, including over collateralization, interest coverage, and cash flows, are monitored on an on-going basis. We consider the overall credit environment, economic conditions, total projected return on the investment, and overall asset allocation of the portfolio in our decisions to purchase or sell CLO and other ABS.

MBS PortfolioOverall, our allocation to these sectors negatively impacted by COVID-19 is not significant, and these positions were in an aggregate net unrealized gain at December 31, 2020. The net unrealized gain position of the consumer cyclical and energy sectors at December 31, 2020, and 2019, was as follows:

($ in millions)December 31, 2020December 31, 2019
Consumer cyclicals$7.5 4.7 
Energy$7.6 3.8 

While these sectors are not material to our fixed income securities portfolio, we continue to monitor them in light of the impact of the COVID-19 pandemic.

Mortgage-Backed Securities (RMBS and CMBS Portfolios)
Mortgage-backed securities represent our most significant exposure to real estate, and further breakdown of this exposure is provided in the table above. Agency RMBS represented 91% of our RMBS allocation, and 13% of our invested assets, as of December 31, 2020.These securities are rated “AAA" and had an unrealized gain of approximately $50 million as of December 31, 2020.

To additionally manage and mitigate exposure on our MBS portfolio (CMBSRMBS and RMBS),CMBS portfolios, we perform analysis both at the time of purchase and as part of the ongoing portfolio evaluation. This analysis includes review of loan-to-value ratios, geographic spread of the assets securing the bond, delinquencies in payments foron the underlying mortgages, gains/losses on sales, evaluations of projected cash flows, as well as other information that aids in determination of the health of the underlying assets. We consider the overall credit environment, economic conditions, the investment's total projected return, on the investment, and overall portfolio asset allocation of the portfolio in our decisionsdeciding to purchase or sell MBS.these securities.

CLO and Other ABS Portfolio
For CLO and other ABS, the primary risk is credit risk. We manage this risk by evaluating a number of factors, including the deal's structure, the credit quality of underlying loans or assets, the composition of the underlying portfolio, and the portfolio manager's track record and capabilities. We monitor key performance metrics, including over-collateralization, interest coverage, and cash flows, on an on-going basis. We consider the overall credit environment, economic conditions, the investment's total projected return, and overall portfolio asset allocation in our deciding to purchase or sell CLO and other ABS. Other ABS includes structured note obligations and securities collateralized by loans and other financial assets, including, without limitation, auto loans, credit card receivables, equipment leases, and student loans.

Equity Price Risk
Our equity securities portfolio is exposed to risk arising from potential volatility in equity market prices. We attempt to minimize the exposure to equity price risk exposure by maintaining a diversified portfolio and limiting concentrations in any one company or industry. The following table presents the hypothetical increases and decreases in 10% increments in market value of the equity portfolio as of December 31, 2017:2020:

In addition to our equity securities, we invest in certain other investments that are also subject to price risk. Our other investments primarily include alternative investments in private limited partnerships that invest in various strategies such as private equity, energy/power generation, middle marketdirect lending, mezzanine debt,financing, distressed debt, infrastructure, and real estate. As of December 31, 2017,2020, other investments represented 2%4% of our total invested assets and 8%10% of our stockholders’ equity. These investments are subject to the risks arising from the fact that their valuation is inherently subjective. The general partner of each of these partnerships usually reports the change in the value of the interests in the partnership on a one quarter lag because of the nature of the underlying assets or liabilities. Since these partnerships' underlying investments consist primarily of assets or liabilities for which there are no quoted prices in active markets for the same or similar assets, the valuation of interests in these
72



partnerships are subject to a higher level of subjectivity and unobservable inputs than substantially all of our other investments. Each of these general partners is required to determine the partnerships' value by the price obtainable for the sale of the interest at the time of determination. Valuations based on unobservable inputs are subject to greater scrutiny and reconsideration from one reporting period to the next, and therefore, may be subject to significant fluctuations, which could lead to significant decreases from one reporting period to the next. As we record our investments in these various partnerships under the equity method of accounting, any decreases in the valuation of these investments would negatively impact our results of operations. For additional information regarding these alternative investment strategies, see Note 5. “Investments” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.


In additionLiquidity Risk
As a property and casualty insurer, our liquidity needs are generally met through the cash flow provided by our on-going operations, as premium collections and investment income generated from our portfolio provide a significant flow of cash to the above,support policyholder claims and other payment obligations. Additionally, we purchase substantial reinsurance at low retention levels to mitigate exposure to significant loss events and we have a defined benefit pension plan with $363.1 million in invested assets as of December 31, 2017, of which approximately 60% was invested in assets subjectaccess to equity price risk. The value of these invested assets is an important element of expensevarious borrowing facilities if the need to raise capital were to arise. See the "Financial Condition, Liquidity, and liability measurement for our pension plan. For additional information regarding the fair value of our pension assets, refer to Note 14. "Retirement Plans"Capital Resources" section in Item 8. “Financial Statements7. "Management's Discussion and Supplementary Data.”Analysis of Financial Condition and Results of Operations" of this Form 10-K for additional information regarding our available borrowing capacity. In addition to this, we monitor our investment portfolio's liquidity profile to ensure it meets our operational liquidity needs. The liquidity characteristics of our portfolio are illustrated below:

Report of Independent Registered Public Accounting Firm
 
TheTo the Stockholders and Board of Directors and Stockholders
Selective Insurance Group, Inc.:


Opinion on the Consolidated Financial Statements
 
We have audited the accompanying consolidated balance sheets of Selective Insurance Group, Inc. and its subsidiaries (the “Company”"Company") as of December 31, 20172020 and 2016, and2019, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three‑year period ended December 31, 2017,2020, and the related notes and financial statement schedules I to V (collectively, the "financial"consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20172020 and 2016,2019, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017,2020, in conformity with U.S. generally accepted accounting principles.In connection with our audits of the consolidated financial statements, we also have audited financial statement schedules I to V. Also in our opinion, the related consolidated financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.
We also have 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, 2017,2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, (COSO), and our report dated February 19, 2018,12, 2021 expressed an unqualified opinion on the effectiveness of the Company’s internal controlscontrol over financial reporting.
Basis for Opinion
These consolidated financial statements and financial statement schedules are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements financial statement schedules 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 auditsaudit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the riskrisks of material misstatement of the consolidated 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 supportingregarding the amounts and disclosures in the consolidated 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 consolidated financial statement presentation.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 consolidated 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 consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgment. The communication of a critical audit matter does not alter in any way our opinion on the consolidated 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.

Estimate of reserve for loss and loss expense
As discussed in Notes 2 and 10 to the consolidated financial statements, the Company estimates the reserve for loss and loss expense (reserves) through an internal reserve review that relies upon methods consistent with actuarial standards of practice supplemented with other internal and external information. The Company develops reserve estimates by line of business and, as experience emerges and other information develops, the reserve estimates are assessed in aggregate and adjusted as necessary. As of December 31, 2020, the Company recorded a liability of $4.26 billion for reserves.
74



We identified the evaluation of the estimate of reserves for loss and loss expense as a critical audit matter. The process to evaluate the Company’s estimate of reserves involved a high degree of subjective auditor judgment due to the inherent uncertainties in adjusting past experience for current development and anticipating trends for predicting future events. These uncertainties may be affected by a number of considerations, including internal factors, such as changes to underwriting and claims practices, supplemental data regarding claims reporting and settlement trends, exposure estimates for reported claims, potential large or complex claims, and additional trends observed by claims personnel or defense counsel, and external factors such as legislative and regulatory enactments, judicial trends and decisions, social trends, and trends in general economic conditions. Evaluating the impact of these factors on the estimate of reserves also required specialized actuarial skills and knowledge.
The following are the primary procedures we performed to address this critical audit matter. With the involvement of actuarial professionals, when appropriate, we evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s internal reserve review and determination of the Company’s best estimate of recorded reserves. We also involved actuarial professionals with specialized skills and knowledge, who assisted in:
evaluating the Company’s actuarial methods by comparing them to methods consistent with actuarial standards of practice;
developing an independent estimate of reserves for certain lines of business using methods consistent with actuarial standards of practice;
for certain other lines of business, assessing the Company's internal reserve review by evaluating the assumptions and actuarial methods used;
developing a consolidated range of reserves and comparing it to the Company's recorded reserves;
assessing movement of the Company’s recorded reserves within the consolidated range of reserves.

Note 2. Summary of Significant Accounting Policies
(a) Principles of Consolidation
The accompanying consolidated financial statements (“Financial Statements”) include the accounts of the Parent and its subsidiaries, and have been prepared in conformity with: (i) United States ("U.S.") generally accepted accounting principles ("GAAP"); and (ii) the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). All significant intercompany accounts and transactions are eliminated in consolidation.
 
(b) Use of Estimates
The preparation of our Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported financial statement balances, as well as the disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

(c) ReclassificationsInvestments

Portfolio Composition and Presentation in the Consolidated Balance Sheet
Our investment portfolio is primarily comprised of fixed income securities. We also hold equity securities, short-term investments, and other investments. In 2017,2020, we reclassified certain line items withinbegan investing in commercial mortgage loans (“CMLs”). A description of our portfolio holdings, and the related presentation in our Consolidated Statements of Income to enhance the ability to analyze our expenses. Specifically, we reclassified our insurance underwriting expenses into amortization of deferred policy acquisition costs and other insurance expenses. These expenses were previously included in policy acquisition costs and other expenses. In addition, all expenses of the Parent, which were previously included in other expenses, are now separately identifiable as corporate expenses on the Consolidated Statements of Income. All prior periods presented in this Form 10-K have been reclassified to reflect this change.Balance Sheet, is provided below.
(d) Investments
Fixed Income Portfolio
We hold the following types of securities in our fixed income securities portfolio:
U.S. government and government agency obligations;
Foreign government obligations;
State and municipal obligations, including special revenue and general obligation bonds;
Corporate securities, which may include investment grade and below investment grade rated bonds, bank loan investments, redeemable preferred stocks,stock, and non-redeemable preferred stocksstock with certain debt-like characteristics, mortgage-backed securities (“MBS”), collateralizedcharacteristics;
Collateralized loan obligations ("CLO"CLOs"), and other asset-backed securities (“ABS”("ABS");
Residential mortgage-backed securities ("RMBS"); and
Commercial mortgage-backed securities ("CMBS"). MBS, CLO, and other ABS are jointly referred to as structured securities. Fixed

The amortized cost of fixed income securities is adjusted for the amortization of premiums and the accretion of discounts over the expected life of the security using the effective yield method. Callable debt securities held at a premium are amortized to the earliest call date. Premiums and discounts arising from the purchase of structured securitiesRMBS, CMBS, CLO and other ABS are amortized over the expected life of the security based on future principal payments, giving additional consideration to prepayments. These prepayments are estimated based on historical and projected cash flows. Prepayment assumptions are reviewed quarterly and adjusted to reflect actual prepayments and changes in expectations. Future amortization of any premium and/or discount is adjusted to reflect the revised assumptions. Interest

Accounting for our tax credit investments is dependent on the type of credit we have purchased, as follows:

Federal low income housing tax credits are accounted for under the proportional amortization methodmethod; and all
All other tax credits in our investment portfolio are accounted for using the equity method. Under the proportional amortization method, our share of the investment’s performance is recorded in our Consolidated Statements of Income as a component of “Federal income tax expense.” Under the equity method, our share of distributed and undistributed net income is included in "Net investment income earned" on our Consolidated Statements of Income.

For federal income tax credits accounted for under the equity method, we use the deferral method for recognizing the benefit of the tax credit with the related deferred revenue being recognized in our Consolidated Statements of Income Statement as a component of "Federal income tax expense" proportionately over the life of the investment.


We categorize distributions from our investments accounted for using the equity method on our Consolidated Statement of Cash Flows using the cumulative earnings approach. Under this approach, distributions received are classified as cash flows from operating activities until such time that the cumulative distributions exceed cumulative earnings for the investment. When such an excess occurs, the excess portion of the current period distribution is considered a return of investment and is classified as a cash flow from investing activities.

We evaluate the alternative investments and tax credit investments included in our other investments portfolio to determine whether those investments are variable interest entities ("VIEs") and if so, whether consolidation is required. A VIE is an entity that either has equity investors that lack certain essential characteristics of a controlling financial interest or lack sufficient
82



funds to finance its own activities without financial support provided by other entities. We consider several significant factors in determining if our investments are VIEs and if we are the primary beneficiary, including whether we have:have (i) the power to direct activities of the VIE;VIE, (ii) the ability to remove the decision maker of the VIE;VIE, (iii) the ability to participate in making decisions that are significant to the VIE;VIE, and (iv) the obligation to absorb losses and the right to receive benefits that could potentially be significant to the VIE. We have reviewed our alternative and tax credit investments and have concluded that they are VIEs, but that we are not the primary beneficiary and therefore, consolidation is not required.


Presentation in the Consolidated Statement of Income

Net Investment Income Earned
Net investment income earned on our Consolidated Statement of Income includes the following:
Interest income, as well as amortization and accretion, on fixed income securities;
Interest income on CMLs;
Dividend income on equity securities;
Interest income on our short-term investments; and
Income recognized on our alternative and other investments accounted for under the equity method of accounting, except for federal tax credits, as discussed below.

Income related to federal tax credits (either low income housing tax credits or other federal credits) is recorded in our Consolidated Statement of Income as a component of “Federal income tax expense” proportionately over the life of the investment.

Net Realized and Unrealized Investment (Losses) Gains
Net realized and unrealized investment losses and gains on our Consolidated Statement of Income include the following:
Realized gains and losses on the saledisposal of investmentsinvestment securities, which are determined on the basis of the cost of the specific investments sold and are creditedsold;
Changes in unrealized gains or chargedlosses on our equity securities;
Losses on securities for which we have the intent to income. Included in realized gains and losses are the other-than-temporary impairment ("OTTI") charges recognized in earnings,sell, which are discussed below.further below; and

On a quarterly basis, we reviewNet credit loss expense or benefit resulting from changes in the ACL related to our investment portfolio, which also is discussed further below.

Losses on securities for impairments that are other than temporary. Interest-related unrealized losses typically do not result in other-than-temporary impairments. The following provides informationwhich we have the intent to sell and ACL on this analysis for our fixed income securities and short-term investments, equity securities, and other investments.

AFS Fixed Income Securities and Short-Term Investments
We review our fixed income securities that are in an unrealized loss position to determine:determine (i) if we have the intent to sell the security;security, or (ii) if it is more likely than not that we will be required to sell the debt security before its anticipated recovery; and (iii) if the decline is other than temporary. Broad changes in the overall market or interest rate environment generally will not lead to a write down.recovery. If we determine that we have either the intent or likely requirement to sell the security, we write down its amortized cost to its fair value through a chargevalue. In writing down amortized cost, any amount previously recorded as an ACL is reversed and any incremental reduction in amortized cost is recorded directly to earnings as a component of “Net realized losses. If we do not have either the intent or requirement to sell the security,and unrealized investment (losses) gains” on our evaluation for OTTI may include, but is not limited to, evaluationConsolidated Statement of the following factors:Income.


Whether the decline appears to be issuer or industry specific;
The degree to which the issuer is current or in arrears in making principal and interest payments on the fixed income security;


The issuer’s current financial condition and ability to make future scheduled principal and interest payments on a timely basis;
Evaluation of projected cash flows;
Buy/hold/sell recommendations published by outside investment advisors and analysts; and
Relevant rating history, analysis, and guidance provided by rating agencies and analysts.

Non-redeemable preferred stocks that are classified asWhen fixed income securities are evaluated under this OTTI method unlessin an unrealized loss position and we do not record any losses on securities for which we intend to sell, we record an ACL for the security is below investment grade, at which time it is evaluated underportion of the equityunrealized loss due to an expected credit loss. We estimate expected credit losses on fixed income securities OTTI model discussed below.

To determine if an impairment is other than temporary, we perform assessments that may include, but are not limited to,by performing a discounted cash flow analysis ("DCF"(“DCF”). The ACL is the equal to determine the security'sexcess of amortized cost over the greater of: (i) our estimate of the present value of expected future cash flows. This analysisflows, or (ii) fair value. The ACL is recorded as a contra-asset reflected in the carrying value of the investment on the Consolidated Balance Sheet. The initial ACL and any subsequent changes are recorded to earnings as a component of “Net realized and unrealized investment (losses) gains” on our Consolidated Statement of Income. Any remaining unrealized loss is the non-credit amount and is recorded in AOCI. The ACL cannot exceed the unrealized loss of an AFS security and therefore it may fluctuate with changes in the fair value of the security. The ACL is written off against the amortized cost basis in the period in which it is determined uncollectible.

Our DCF analyses calculate the present value of expected future cash flows using various models specific to the major security types in our portfolio. These models use security-specific information as well as forecasted macroeconomic data to determine possible expected credit loss scenarios based on projected changes in the economy. The forecasted economic data incorporated into the models is based on the Federal Reserve Board’s annual supervisory stress test review on certain large banks and financial institutions. We also performed on all previously-impaired debt securities that continuehave the ability to be held by usincorporate internally-developed forecast information into the models as we deem appropriate. The discount rate used in a DCF is one of the following:

The effective interest rate in the expected present valueeffect as of the future cash flows, based on the DCF, from the amortized cost basis of a security is considered a “credit impairment,” with the remaining decline in fair value of a security considered a “non-credit impairment.” Credit impairments are charged to earnings as a component of realized losses, while non-credit impairments are recorded to Other Comprehensive Income ("OCI") as a component of unrealized losses.reporting date for non-fixed rate securities; and

The discount rate we use in a DCF is the effective interest rate implicit in the security at the date of acquisition for those structured securities that were not of high credit quality at acquisition. For all other securities, we use a discount rate that equals the current yield, excluding the impact of previous OTTI charges, used to accrete the beneficial interest. securities.

DCFs may include, but are not necessarily limited to: (i) generating cash flows for each tranche considering tranche-specific data, market data, and other pertinent information, such as the historical performance of the underlying collateral, including net operating income generated by underlying properties, conditional default rate assumptions, loan loss severity assumptions, consensus projections, prepayment projections, and actual pool and collateral information; (ii) identifying applicable benchmark yields; and (iii) applying market-based tranche specific spreads to determine an appropriate yield by incorporating collateral performance, tranche-level attributes, trades, bids, and offers.
Equity Securities
We review securities that are in an unrealized loss position to determine: (i) if we do not intend to holdrecord a valuation allowance on the accrued interest balance associated with our fixed income securities as we reverse delinquent amounts on a timely basis. We consider a fixed income security to its forecasted recovery;be past due at the time any principal or (ii) ifinterest payments become 90 days delinquent.

ACL on CMLs
We evaluate our CMLs on a quarterly basis for expected credit losses. If we hold a CML with a specific credit concern, we record an individual ACL on that loan. For all other CMLs, we record an ACL on the declinepool of loans based on lifetime expected credit losses. The ACL is other than temporary, which includes declines driven by market volatility for which we cannot assert the security will recoverrecorded as a contra-asset reflected in the near term. If we determine either that we do not intend to hold a security, orcarrying value of our CMLs on the decline is other than temporary, we write down the security's cost to its fair value through a chargeConsolidated Balance Sheet. Our initial ACL and any subsequent changes are recorded to earnings as a component of “Net realized losses. and unrealized investment (losses) gains” on our Consolidated Statement of Income.

We utilize a forecasting model to estimate lifetime expected credit losses at a loan level under multiple economic scenarios. The scenarios use macroeconomic data such as unemployment and inflation to project property-specific operating income and capitalization rates that are used to estimate the value of the future operating income stream. This information, coupled with historical data about mortgage loan performance, is used to project the probability of default, the amount of loss given a default, and the resulting lifetime expected loss.

Losses on securities for which we have the intent to sell and Credit Losses on Other Investments
If we determine that we intend to holdsell a holding in our investment portfolio and the security, our evaluation for OTTI may include, but is not limited to, an evaluationexpected proceeds are less than the recorded value of the following factors:

(e)(d) Fair Values of Financial Instruments


Assets
The fair values of our investments are generated using various valuation techniques and are placed into the fair value hierarchy considering the following: (i) the highest priority is given to quoted prices in active markets for identical assets (Level 1); (ii) the next highest priority is given to quoted prices in markets that are not active or inputs that are observable either directly or indirectly, including quoted prices for similar assets in markets that are not active and other inputs that can be derived principally from, or corroborated by, observable market data for substantially the full term of the assets (Level 2); and (iii) the lowest priority is given to unobservable inputs supported by little or no market activity and that reflect our assumptions about the exit price, including assumptions that market participants would use in pricing the asset (Level 3). An asset’s classification within the fair value hierarchy is based on the lowest level of significant input to its valuation. Transfers between levels in the fair value hierarchy are recognized at the end of the reporting period.

84



The techniques used to value our financial assets are as follows:


Level 1 Pricing
Security TypeMethodology
Equity Securities; U.S. Treasury NotesEquity and U.S. Treasury Note prices are received from an independent pricing service that are based on observable market transactions. We validate these prices against a second external pricing service, and if established market value comparison thresholds are breached, further analysis is performed to determine the price to be used.
Short-Term InvestmentsShort-term investments are carriedrecorded at cost, which approximates fair value. Given the liquid nature of our short-term investments, we generally validate their fair value by way of active trades within approximately one week of the financial statement close.


Level 2 Pricing
We utilize a market approach for our Level 2 securities, using primarily matrix pricing models prepared by external pricing services. Matrix pricing models use mathematical techniques to value debtfixed income securities by relying on the securities' relationship to other benchmark quoted securities, and not relying exclusively on quoted prices for specific securities, as the specific securities are not always frequently traded. As a matter of policy, we consistently use one pricing service as our primary source and secondary pricing services if prices are not available from the primary pricing service. Fixed income securities portfoliosecurity pricing is reviewed for reasonableness in the following ways:by (i) comparing our pricing to other third-party pricing services as well as benchmark indexed pricing;pricing, (ii) comparing fair value fluctuations between months for reasonableness; andreasonableness, (iii) reviewing stale prices.prices, and (iv) internally reviewing prices for reasonableness if a price from another third-party source is not available. If further analysis is needed, a challenge is sent to the pricing service for review and confirmation of the price.


Further information on our Level 2 asset pricing is included in the following table:
Security TypeMethodology
Corporate Securities including preferred stocks classified as Fixed Income Securities, and U.S. Government and Government AgenciesEvaluations include obtaining relevant trade data, benchmark quotes and spreads, and incorporating this information into either spread-based or price-based evaluations as determined by the observed market data. Spread-based evaluations include: (i) creating a range of spreads for relevant maturities of each issuer based on the new issue market, secondary trading, and dealer quotes; and (ii) incorporating option adjusted spreads for issues that have early redemption features. Based on the findings in (i) and (ii) above, final spreads are derived and added to benchmark curves. Price-based evaluations include matching each issue to its best-known market maker and contacting firms that transact in these securities.
Obligations of States and Political Subdivisions

Evaluations are based on yield curves that are developed based on factors such as: (i) benchmarks to issues with interest rates near prevailing market rates; (ii) established trading spreads over widely-accepted market benchmarks; (iii) yields on new issues; and (iv) market information from third-party sources such as reportable trades, broker-dealers, or issuers.
Structured Securities (includingRMBS, CMBS, CLO and other ABS Commercial Mortgage-Backed Securities ("CMBS"), Residential Mortgage-Backed Securities ("RMBS"))

Evaluations are based on a DCF, including: (i) generating cash flows for each tranche considering tranche-specific data, market data, and other pertinent information, such as historical performance of the underlying collateral, including net operating income generated by the underlying properties, conditional default rate assumptions, loan loss severity assumptions, consensus projections, prepayment projections, and actual pool and loan level collateral information; (ii) identifying applicable benchmark yields; and (iii) applying market-based tranche-specific spreads to determine an appropriate yield by incorporating collateral performance, tranche-level attributes, trades, bids, and offers.
Foreign Government

Evaluations are performed using a DCF model and by incorporating observed market yields of benchmarks as inputs, adjusting for varied maturities.




Level 3 Pricing
Less than 1% of our portfolio cannot be priced using our primary or secondary pricing service. At times, we may use non-binding broker quotes to value some of these securities. These prices are from various broker/dealers that use bid or ask prices, or benchmarks to indices, in measuring the fair value of a security. We review these fair value measurements for reasonableness. This review typically includes an analysis of price fluctuations between months with variances over established thresholds being analyzed further.

Further information on our current Level 3 asset pricing is included in the following table:

See Note 7. “Fair Value Measurements” for a summary table of the fair value and related carrying amounts of financial instruments.

(f)(e) Allowance for Doubtful AccountsCredit Losses on Premiums Receivable
We estimate an allowance for doubtful accountsACL on our outstanding premiums receivable. Thisreceivable balance at each reporting date. In determining this allowance, iswe use a method that considers the aging of the receivable, based on the effective year of the related policy, along with our historical write-off percentages adjusted forreceivable loss experience. We also contemplate expected macroeconomic conditions over the effectsexpected collection period, which are short-term in nature because the majority of currentthe balances are collected within two years of policy issuance.

As experienced during the COVID-19 pandemic, in contemplating our ACL on premiums receivable we also consider (i) the higher risk of non-payment due to a significant decline in economic activity, (ii) individualized payment flexibility offered to our customers, and anticipated trends. An account(iii) moratoriums on policy cancellations, late payment notices, and late or reinstatement fees.

Changes in our ACL are charged to earnings as credit loss expense or benefit, which is charged offa component of "Other insurance expenses" on our Consolidated Statements of Income, with an offsetting ACL recorded as a contra-asset reflected in the carrying value of the receivable. We charge write-offs against the allowance when we believe it is probable that we will not collect a receivable. In making this determination, we considerdetermine the account to be uncollectible after considering information obtained from our efforts to collect amounts due directly or through collection agencies.efforts.

(g)(f) Share-Based Compensation
Share-based compensation consists of all share-based payment transactions in which an entity acquires goods or services by issuing (or offering to issue) its shares, share units, share options, or other equity instruments. The cost resulting from all share-based payment transactions are recognized in the Financial Statements based on the fair value of both equity and liability awards. The fair value is measured at grant date for equity awards, whereas the fair value for liability awards are remeasured at each reporting period. The fair value of both equity and liability awards is recognized over the requisite service period. The requisite service period is typically the lesser of the vesting period or the period of time from the grant date to the date of retirement eligibility. The expense recognized for share-based awards, which, in some cases, contain performance criteria, is based on the number of shares or units expected to be issued at the end of the performance period. We repurchase the Parent’s stock from our employees in connection with tax withholding obligations, as permitted under our stock-based compensation plans. This activity is disclosed in our Consolidated StatementsStatement of Stockholders' Equity.


(h)(g) Reinsurance
Reinsurance recoverables represent estimatesThe “Reinsurance recoverable” balance on our Consolidated Balance Sheet represents our estimate of amounts that will be recovered from reinsurers under our various treaties. Generally, amounts recoverable from reinsurers are recognized as assets at the same time and in a manner consistent with the paid and unpaid losses associated with the reinsured policies. We would consider a recoverable balance from a reinsurer to be past due if payment is not received by the first day following the invoice due date. We require collateral to secure reinsurance recoverablesrecoverable balances primarily from our reinsurance carriers that are not authorized, otherwise approved, or certified to do business in one or more of our ten insurance subsidiaries' domiciliary states. Our ten insurance subsidiaries are collectively referred to as the


"Insurance "Insurance Subsidiaries." ThisThe collateral received is typically in the form of a letter of credit, trust funds, or cash. Anfunds withheld against reinsurance recoverables.

We estimate an ACL on our outstanding reinsurance recoverable balance at each reporting date. Credit risk is mitigated to the extent we have obtained collateral. As part of our estimation of the ACL, we reduce the recoverable balance by the amount of the collateral. We then pool the uncollateralized balances by similar risk characteristics, including the financial strength rating of the reinsurer, and use a probability-of-default methodology to calculate the allowance. Historical default rates are sourced from AM Best and are coupled with severity assumptions in developing a baseline scenario. We then stress this scenario by incorporating forecasts of industry catastrophe losses and economic factors sourced through third-party data providers. In
86



developing our best estimate of the allowance for estimated uncollectible reinsurancecredit losses, we consider our outlook as to the probability of each of these scenarios occurring.

Changes in our ACL are charged to earnings as credit loss expense, which is a component of “Loss and loss expense incurred” on our Consolidated Statement of Income, with an offsetting ACL recorded based on an evaluationas a contra-asset reflected in the carrying value of balances due from reinsurers and other available information, such as each reinsurers' credit rating from A.M. Best Company ("A.M. Best") or Standard & Poor's Rating Services ("S&P").the recoverable balance. We charge off reinsurance recoverables on paid losseswrite-offs against the ACL when it becomes probable that we will notdetermine the recoverable balance to be uncollectible after considering information obtained from our efforts to collect amounts due or through a review of the balance.financial condition of the reinsurer.
 
(i)(h) Property and Equipment
Property and equipment used in operations, including certain costs incurred to develop or obtain computer software for internal use, are capitalized and carriedrecorded at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. The following estimated useful lives can be considered as general guidelines:

Asset CategoryYears
Computer hardware3
Computer software3 to 5

We recorded depreciation expense of $17.8$21.5 million, $17.4$18.7 million, and $16.4$19.5 million for 2017, 2016,2020, 2019, and 2015,2018, respectively.


(j)(i) Deferred Policy Acquisition Costs
Deferred policy acquisition costs are limited to costs directly related to the successful acquisition of insurance contracts. Costs meeting this definition typically include, among other things, sales commissions paid to our distribution partners, premium taxes, and the portion of employee salaries and benefits directly related to time spent on acquired contracts. These costs are deferred and amortized over the life of the contracts.


Accounting guidance requires a premium deficiency analysis to be performed at the level an entity acquires, services, and measures the profitability of its insurance contracts. We currently perform three premium deficiency analyses for our insurance operations, consistent with our reportable segments of Standard Commercial Lines, Standard Personal Lines, and E&S Lines. A combined ratio of over 100% does not necessarily indicate a premium deficiency, as any year's combined ratio includes a portion of underwriting expenses that are expensed at policy inception and therefore are not covered by the remaining unearned premium. In addition, investment income is not contemplated in the combined ratio calculation.


There were no premium deficiencies for any of the reported years, as the sum of the anticipated loss and loss expense, unamortized acquisition costs, policyholder dividends, and other expenses for each segment did not exceed that segment’s related unearned premium and anticipated investment income. The investment yields assumed in the premium deficiency assessment for each reporting period, which were based on our actual average investment yield before tax as of the September 30 calculation date, were 2.9%3.0% for 2017, 2.4%2020, 3.5% for 2016,2019, and 2.5%3.3% for 2015.2018.
 
(k)(j) Goodwill
Goodwill results from business acquisitions where the cost of assets and liabilities acquired exceeds the fair value of those assets and liabilities. A quantitative goodwill impairment analysis is performed if our quarterly qualitative analysis indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Goodwill is allocated to the reporting units for purposes of these analyses. Based on our analysis at December 31, 2017,2020, goodwill was not impaired.
 
(l) Reserves(k) Reserve for Loss and Loss Expense
Reserves for loss and loss expense are comprised of bothincludes case reserves on individualreported claims and reserves for claimsknown as incurred but not reported ("IBNR"). reserves. Case reserves result from claims that have been reported to one or more of our Insurance Subsidiaries, and are estimated on each individual claim, and based on claim-specific facts and circumstances known at the amount oftime. The case reserves may be adjusted upward or downward as the expected ultimate payment.specific facts and circumstances change. IBNR reserves are established at more aggregated levels than case basis reserves, and in addition to reserves on claims that have been incurred but not reported, they include provisions for (i) claims not yet reported, (ii) future emergencedevelopment on knownreported claims, as well as(iii) previously closed claims that will be reopened claims. IBNRin the future, and (iv) anticipated salvage and subrogation recoveries.

We evaluate our reserves quarterly, through our comprehensive reserve review process and adjustments to recorded reserves are established based onmade accordingly. The primary input in evaluating reserve levels is the results of the Insurance Subsidiaries’quarterly reserve review prepared by our internal reserve analysis, supplemented with other internal and external information.

The internal reserve analysis is performed quarterly, and relies upon generally accepted actuarial techniques.  Such techniques assume that past experience, adjusted for the effects of current developments and anticipated trends, are an appropriate basis for predicting future events. Our analyses rely upon historical paid and caseactuaries, which provides comprehensive loss and loss expense projections. Our reviews are based primarily on our own loss experience, organized by line of business, accident year, and maturity (i.e., “triangles”). Standardbusiness. Where sufficient statistical credibility exists, we may further segment the experience by coverage within line, or by geographic area. Generally accepted actuarial projection methodsmethodologies are applied to this history,


producing a set of estimatedthese reserve groups to produce ultimate loss and loss expenses. Ultimateexpense projections.

Typically, we organize our experience by accident year and age, which lends itself to the application of various loss development methods. These methods rely on historical claims reporting and payment patterns to project ultimate loss or expense for open accident years. Consideration is also given to the prior loss estimate, particularly for longer-tailed lines of business and the current accident year. For the current accident year, this expectation comes from our detailed actuarial planning process. The initial estimate is adjusted over time as actual experience emerges.

These methods require numerous assumptions, such as the selection of loss and loss expense development factors and the weight applied to each individual projection method, among others. Therefore, no single method can be interpreted as definitive. Instead, ultimate loss and loss expenses are selected frombased upon the various methods, considering the strengths and weaknesses of the methodseach as they applyit applies to the specific line of business and accident year.


Certain types of exposuresliabilities, by their nature, do not lend themselves to standard actuarialloss development methods. Examples of these are:

Certainincludes property catastrophe events may be low in frequency and catastrophes (low frequency/high in severity. These events may affect many insureds simultaneously. Due to theseverity, unique nature of these events, ultimate liabilitiesevents), latent claims (where losses are estimated for each event, based on surveys of our portfolio of exposures, in conjunction with individual claims estimates. While generally short-tailed, the liabilities associated with these events are subject to a higher degree of uncertainty. We maintain significant reinsurance protection that greatly limits the impact that these extreme events have on net loss and loss expenses.

Some insured events may span multiple years and trigger multiple policies, as in the case of asbestos and environmental claims, where the injury is deemed to occurincurred over an extended period of time. These types of losses often do not lend themselves to traditional actuarial methods. Where we deem appropriate, our experience may be analyzed without differentiating by accident year, using alternative methodstime), and metrics. In these cases, the associated selected ultimate loss andunallocated loss expenses are then allocated to the applicable accident years for reporting.

Another example of non-standard methods relate to loss(loss expenses that cannot be attributed to a specific claim (referred toclaim). Alternate development techniques are used for these liabilities, which include individual claims reviews, calendar year counts and averages, aggregate benchmark measures such as “unallocatedpaid and incurred “survival ratios,” and others. These approaches often require additional assumptions and a greater amount of professional judgement.

The result of the reserve review is a set of ultimate loss expenses”). These expenses are first allocated toand loss expense estimates by line of business, including the current and alternative projection methods are then applied to estimate expenses by calendar year, which are then allocated back toprior accident years. Furthermore, the applicable accident years for reporting.

The selected ultimate losses are separated into their components of claim frequency and severity, along with their associated trends, to provide additional insight. While these ultimate loss and loss adjustment expenses are translated into indicated IBNR reserves, which are then compared to the recorded IBNR reserves. Management's judgment is applied in determining any required adjustments and the resulting adjustments are then recorded and assigned or allocated to accident year using the results of the actuarial analysis.

While the reserve analysis isexpense estimates serve as the primary basis for determining the recorded IBNR reserves, other internal and external factors are considered.considered in our overall reserve review. Internal factors include:include (i) changes to our underwriting and claims practice, (ii) supplemental data regarding claims reporting and settlement trends; (ii)trends, (iii) exposure estimates for reported claims, along with recent development on those estimates with respect to individual large claims and the aggregate of all claims; (iii) the rate at which new(iv) potential large or complex claims, are being reported; and (iv)(v) additional trends observed by claims personnel or reported to them by defense counsel. External factors considered include:include (i) legislative enactments;and regulatory enactments, (ii) judicial decisions;trends and decisions, (iii) legal developments insocial trends, including the determinationimpacts of liability and the imposition of damages;social inflation, and (iv) trends in general economic conditions, including the effects of inflation.inflation, including impacts to medical costs, raw materials, and labor. For example, 2020 presented unique impacts related to COVID-19, such as governmental "stay-at-home" directives and their economic impacts, judicial interpretations of insurance coverages, and social and behavioral changes. While these impacts are uncertain and continue to evolve, they were key considerations in the reserving process.


The combination of the IBNR estimates along with the case reserve estimates on individual claims results in our total reserves for loss and loss expense. These reserves are expected to be sufficient for settling loss and loss expense obligations under our policies on unpaid claims, including changes in the volume of business written, claims frequency and severity, the mix of business, claims processing, and other items that management expects to affect our ultimate settlement of loss and loss expense. However, our loss and loss expense reserves are estimates of future events, the outcomes of which are not yet known. As with all estimates, they carry inherent uncertainty, which may be driven by internal factors, such as changes to our claims or underwriting operations, or external factors, such as changes in legislative, judicial, economic, or social trends. Furthermore, actual outcomes are impacted by inherent randomness, such as the actual number of accidents/incidents, or the occurrence or non-occurrence of a single large event. Because of these uncertainties, it is possible that actual outcomes will differ materially from the reserves established. While this risk cannot be eliminated, we review our reserves quarterly based upon the information available at that time, and make adjustments to our ultimate loss and loss expense estimates accordingly. These changes in our ultimate loss and loss expense estimates are reflected in the Consolidated Statements of Income for the period in which such estimates are changed. Any changes in the liability estimate could be material to the results of operations in future periods.

Loss reserves are estimates, and as such, we also consider a range of possible loss and loss expense reserve estimates. This range is determined at the beginning of each year, using prior year-end data, and reflects the fact that there is no single precise method for estimating the required reserves, due to the many factors that may influence the amounts ultimately paid.  Considering the reserve range along with all of the items described above, as well as current market conditions, IBNR estimates are then established and recorded.

The combination of the IBNR estimates along with the case reserve estimates on individual claims results in our total reserves for loss and loss expense.  These reserves are expected to be sufficient for settling losses and loss reserve obligations under our policies on unpaid claims, including changes in the volume of business written, claims frequency and severity, the mix of business, claims processing, and other items that management expects to affect our ultimate settlement of loss and loss expense. However, the ultimate claim settlements may be higher or lower than reserves established. As our experience emerges and other information develops, we revise our reserve estimates accordingly. The changes in these estimates, resulting from the continuous review process and the differences between estimates and ultimate payments, are reflected in the Consolidated Statements of Income for the period in which such estimates are changed. The associated impacts may be material to the results of operations in future periods.


We do not discount to present value that portion of our lossesloss and loss expense reserves expected to be paid in future periods.

Our loss and loss expense reserves implicitly include anticipated recoveries for salvage and subrogation claims.

88



Claims are counted at the occurrence, line of business, and policy level. For example, if a single occurrence (e.g. an autoautomobile accident) leads to a claim under an autoautomobile and an associated umbrella policy, they are each counted separately. Conversely, multiple claimants under the same occurrence/line/policy would contribute only a single count. The claim counts provided are


on a reported basis. A claim is considered reported when a reserve is established or a payment is made. Therefore, claims closed without payment are included in the count as long as there was an associated case reserve at some point in its life cycle.


We also write a small amount of assumed reinsurance.  Currently, this business is limited to our share of certain involuntary pools.  Since the associated claims are not processed by us, they are not captured within our claims system. Therefore, the claim counts reported exclude this business.

(m)(l) Revenue Recognition
Premiums written are recognized as revenue over the period that coverage is provided using the semi-monthly pro-rata method. Unearned premiums and prepaid reinsurance premiums represent that portion of premiums written that are applicable to the unexpired terms of policies in force.

The Insurance Subsidiaries' net premiums written (“NPW”) include direct insurance policy writings, plus reinsurance assumed, and estimates of premiums earned but unbilled on the workers compensation and general liability lines of insurance, less reinsurance ceded. The estimated premium on the workers compensation and general liability lines is referred to as audit premium. We estimate this premium, as it is anticipated to be either billed or returned on policies subsequent to expiration based on exposure levels (i.e. payroll or sales). Audit premium when it is reasonably possible to do so based on historical trends adjusted for the uncertainty of future economic conditions. Economic instability could ultimately impact our estimates and assumptions, and changes in ourIf we determine it is not reasonably possible to estimate may be material to the results of operations in future periods. Premiums written are recognized as revenue over the period that coverage is provided using the semi-monthly pro-rata method. Unearned premiums and prepaid reinsurance premiums represent that portion of premiums written that are applicable to the unexpired terms of policies in force.this premium, we do not do so.
 
(n)(m) Dividends to Policyholders
We establish reserves for dividends to policyholders on certain policies, most significantly workers compensation policies. These dividends are based on the policyholders' loss experience. Dividend reserves are established based on past experience, adjusted for the effects of current developments and anticipated trends. The expense for these dividends is recognized over a period that begins at policy inception and ends with the payment of the dividend. We report these dividends within "Other insurance expenses" on the Consolidated Statement of Income. We do not issue policies that entitle the policyholder to participate in the earnings or surplus of our Insurance Subsidiaries.


(o)(n) Federal Income Tax
We use the asset and liability method of accounting for income taxes. Current federal income taxes are recognized for the estimated taxes payable or refundable on tax returns for the current year. Deferred federal income taxes arise from the recognition of temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities. We consider all evidence, both positive and negative, with respect to our federal tax loss carryback availability, expected levels of pre-tax financial statement income, and federal taxable income, when evaluating whether the temporary differences will be realized. In projecting future taxable income, we begin with budgeted pre-tax income adjusted for estimated non-taxable items. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates we use to manage our businesses. A valuation allowance is established when it is more likely than not that some portion of the deferred tax asset will not be realized. A liability for uncertain tax positions is recorded when it is more likely than not that a tax position will not be sustained upon examination by taxing authorities. The effect of a change in tax rates is recognized in the period of enactment. If we were to be levied interest and penalties by the Internal Revenue Service, (“IRS”), the interestthese amounts would be recognized as “Interesta component of “Total federal income tax expense” and the penalties would be recognized as either “Other insurance expenses” or "Corporate expenses" on the Consolidated StatementsStatement of Income depending on the nature of what caused the occurrence of such an item.

For information regarding the impact of the the recent tax reform, refer to Note 13. "Federal Income Taxes" of this Form 10-K.Income.
 
(p)(o) Leases
We have various operating leases for office space, equipment, and fleet vehicles. RentalIn addition, we have various finance leases for computer hardware.

We determine if an arrangement is a lease on the commencement date of the contract. Lease assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. The lease asset and liability are measured by the present value of the future minimum lease payments over the lease term. Our fleet vehicle leases include a residual value guarantee; however, the residual value guarantee is not probable of being owed. Therefore, there is no impact to the lease liability or lease asset. To measure the present value, we use the discount rate in the contract. If the discount rate is not readily determinable, our incremental borrowing rate is used. The lease asset is then adjusted to exclude lease incentives. We recognize variable lease payments in the periods in which the obligations for those payments are incurred. In calculating a lease liability, we include options to extend or terminate the lease if it is reasonably certain that we will exercise such option. Lease expense for suchis calculated using the straight-line method. In addition, we have adopted accounting policy elections to: (i) aggregate lease and non-lease components into a single lease component; and (ii) expense short-term leases is recorded on a straight-line basis over the lease term. If a lease has a fixed and determinable escalation clause, or periods of rent holidays, the difference between rental expense and rent paid is included in "Other liabilities" in the Consolidated Balance Sheets.


In addition, we have various capital leases for computer hardware and software. These leases are accounted for as an acquisition of an asset with a corresponding obligation. Depreciation is calculated using the straight-line method over the shorter of the estimated useful life of the asset or the lease term.
89



(q)(p) Pension
Our pension and post-retirement life benefit obligations and related costs are calculated using actuarial methods, within the framework of GAAP. Our pension benefit obligation is determined as the actuarial present value of the vested benefits to which the employee isemployees are currently entitled, based on the average life expectancy of the employee.employees. Our funding policy provides that payments to our pension trust shall be equal to the minimum funding requirements of the Employee Retirement Income Security Act of 1974 ("ERISA"), plus additional amounts that the Board of Directors ("Board") of Selective Insurance Company of America (“SICA”) may approve from time to time.




Two key assumptions, the discount rate and the expected return on plan assets, are important elements of expense and/or liability measurement. We evaluate these key assumptions annually unless facts indicate that a more frequent review is required. The discount rate enables us to state expected future cash flows at their present value on the measurement date. The purpose of the discount rate is to determine the interest rates inherent in the price at which pension benefits could be effectively settled. Our discount rate selection is based on high-quality, long-term corporate bonds. To determine the expected long-term rate of return on the plan assets, we consider the current and expected asset allocation, as well as historical and expected returns on each plan asset class. Other assumptions involve demographic factors such as retirement age and mortality. A portion of our plan assets is allocated to a liability hedging strategy through which we have an expectation that our plan assets will move in tandem with a portion of the plan liabilities, helping to mitigate funding ratio volatility.
 
Note 3. Adoption of Accounting Pronouncements
In MarchJune 2016, the Financial Accounting Standards Board ("FASB"(“FASB”) issued Accounting StandardStandards Update ("ASU") 2016-09, Compensation - Stock Compensation: Improvements to Employee Share-based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions. We adopted this guidance in the first quarter of 2017, which resulted in the following impacts on our consolidated financial statements:
Consolidated Statements of Income
The new standard requires that the tax effects of share-based compensation be recognized in the income tax provision as discrete items outside of the annual estimated expected tax rate. In addition, all excess tax benefits and tax deficiencies should be recognized as income tax benefit or expense in the income statement. Previously, these amounts were recorded in additional paid-in capital. In addition, in calculating potential common shares used to determine diluted earnings per share, GAAP requires us to use the treasury stock method. The new standard requires that assumed proceeds under the treasury stock method be modified to exclude the amount of excess tax benefits that would have been recognized in additional paid-in capital. These changes were adopted on a prospective basis. As a result of adoption, we recognized an income tax benefit in the Consolidated Statements of Income of $4.3 million in 2017 related to stock grants that have vested this year.

In recording share-based compensation expense, the standard allows companies to make a policy election as to whether they will include an estimate of awards expected to be forfeited or whether they will account for forfeitures as they occur. We have elected to include an estimate of forfeitures in the computation of our share-based compensation expense. As this treatment is consistent with previous guidance, this election had no impact on our consolidated financial statements.
Consolidated Statements of Cash Flows
ASU 2016-09 requires that excess tax benefits from share-based awards be reported as operating activities in the consolidated statement of cash flows. Previously, these cash flows were included in financing activities. We elected to apply this change on a prospective basis; therefore, no changes have been made to the prior periods disclosed in this report.

ASU 2016-09 also requires that employee taxes paid when an employer withholds shares for tax-withholding purposes be reported as financing activities in the consolidated statement of cash flows. This requirement has no impact to us as we have historically reported these cash flows as part of financing activities.
In October 2016, the FASB issued ASU 2016-17, Consolidation: Interests Held through Related Parties That Are under Common Control ("ASU 2016-17"). ASU 2016-17 changes how a decision maker considers indirect interests in a VIE held under common control in making the primary beneficiary determination. We adopted ASU 2016-17 in the first quarter of 2017. This adoption did not impact us, as we are not the decision maker in any of the VIEs in which we invest.

In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs: Premium Amortization on Purchased Callable Debt Securities ("ASU 2017-08"). ASU 2017-08 revises the amortization period for certain callable debt securities held at a premium, requiring the premium to be amortized to the earliest call date. Under current GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument. ASU 2017-08 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018 with early adoption permitted. We adopted this guidance in the fourth quarter of 2017 and the adoption did not impact us as we amortize premium on these callable debt securities to the earliest call date.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation: Scope of Modification Accounting ("ASU 2017-09"). ASU 2017-09 provides clarification about which changes to the terms or conditions of a share-based payment award would require the application of modification accounting. ASU 2017-09 is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. We adopted this guidance in the fourth quarter of 2017 and the adoption did not impact us, as we currently record modifications in accordance with this ASU.



Pronouncements to be effective in the future
In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 provides guidance to improve certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Specifically the guidance: (i) requires equity investments to be measured at fair value with changes in fair value recognized in earnings; (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (iii) eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost; (iv) requires the use of the exit price notion when measuring the fair value of financial instruments for disclosure purposes; and (v) clarifies that the need for a valuation allowance on a deferred tax asset related to an available-for-sale ("AFS") security should be evaluated with other deferred tax assets.

ASU 2016-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Our adoption of this guidance will require a cumulative-effect adjustment between AOCI and retained earnings on the balance sheet for approximately $25 million, which represents the after-tax unrealized gain on our equity securities portfolio as of December 31, 2017. On a pre-tax basis, the unrealized gain on our equity securities portfolio increased $13 million during 2017 and, had this literature been in effect, we would have recognized additional after-tax net income of approximately $10 million, or $0.17 per diluted share, assuming a 21% corporate tax rate.

In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that fiscal year, with early adoption permitted. ASU 2016-02 requires the application of a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. While we are currently evaluating ASU 2016-02, we do not expect a material impact on our financial condition or results of operations from the adoption of this guidance.

In June 2016, the FASB issued ASU 2016-13,, Financial Instruments - Credit Losses,(“ASU and subsequent additional implementation guidance (collectively referred to as “ASU 2016-13”).  ASU 2016-13 will change that changes the way entities recognize impairment of financial assets by requiringassets. The new guidance requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets including, among others, held-to-maturity debt securities, trade receivables, and reinsurance recoverables. ASU 2016-13 requires a valuation allowance to be calculated on these financial assets and that they be presented onthrough the financial statements netestablishment of the valuation allowance.an ACL. The valuation allowanceACL is a measurement of expected losses that is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This methodology is referredAdditionally, ASU 2016-03 requires the presentation of the impacted financial assets on the Consolidated Balance Sheet net of the ACL.

We adopted this guidance on January 1, 2020, applied a modified retrospective approach for the adoption, and recorded a net cumulative-effect adjustment to asincrease the currentopening balance of 2020 retained earnings by $1.4 million, after tax. As prescribed in ASU 2016-13, we did not adjust the amortized cost basis of any securities for which we previously had recorded other-than-temporary impairment ("OTTI") losses. The cumulative-effect increase to retained earnings represents the net adjustment required to (i) establish the ACL on our held-to-maturity ("HTM") debt securities and (ii) re-estimate the ACL on our premiums receivables and reinsurance recoverables under ASU 2016-13. See Note 2. "Summary of Significant Accounting Policies" of this Form 10-K for accounting policy updates related to ASU 2016-13. Additionally, see Note 5. "Investments," Note 8. "Allowance for Credit Losses on Premiums Receivable," and Note 9. "Reinsurance" of this Form 10-K for additional information regarding expected credit loss model.losses related to the respective financial assets.

In August 2018, the FASB issued ASU 2016-132018-13, Fair Value Measurement: Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). ASU 2018-13 modifies the disclosure requirements for fair value measurements by removing certain disclosures, and modifying and adding disclosure requirements. The additional disclosure requirements include (i) the change in unrealized gains and losses for the period included in other comprehensive income (“OCI”) for recurring Level 3 fair value measurements held at the end of the reporting period, and (ii) the range and weighted average of significant observable inputs used to develop Level 3 fair value measurements. We adopted the provisions related to removed disclosures in the fourth quarter of 2019 and adopted the remaining disclosure requirements in the first quarter of 2020. As it requires disclosure only, ASU 2018-13 has no impact on our financial condition or results of operations.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a cloud computing hosting service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. We adopted this guidance prospectively on January 1, 2020, and it did not have a material impact on our financial condition or results of operations.

Pronouncements to be effective in the future
In December 2019, the FASB issued ASU 2019-12, Income Taxes - Simplifying the Accounting for Income Taxes (“ASU 2019-12”). Among other items, ASU 2019-12 simplifies the accounting treatment of tax law changes and year-to-date losses in interim periods. An entity generally recognizes the effects of a change in tax law in the period of enactment; however, there is an exception for tax laws with delayed effective dates. Under current guidance, an entity may not adjust its annual effective tax
90



rate for fiscal years beginning after December 15, 2019,a tax law change until the period in which the law is effective. ASU 2019-12 provides that all effects of a tax law change, including adjustment of the estimated annual effective tax rate, are recognized in the period of enactment.

For year-to-date losses in interim periods, within thosean entity is required currently to estimate its annual periods. Early adoptioneffective tax rate for the full fiscal year at the end of each interim period and use that rate to calculate its income taxes on a year-to-date basis. When an interim period loss exceeds the anticipated loss for the year, the income tax benefit is permitted, but no earlier than fiscal yearslimited to the amount that would be recognized if the year-to-date loss were the anticipated loss for the full year. ASU 2019-12 removes this limitation and allows an entity to compute its income tax benefit at each interim period based on its estimated annual effective tax rate.

We will adopt this guidance on January 1, 2021 and it will not have a material impact to our financial condition, cash flows, or results of operations upon adoption.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 provides optional expedients and exceptions to the guidance in GAAP on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition away from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. Companies can elect to adopt ASU 2020-04 as of the beginning afterof the interim period that includes March 2020, or any date thereafter through December 15, 2018.31, 2022. We are currently evaluating the impact of this guidance on our financial condition and results of operations.


In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows, including, but not limited to: (i) debt prepayment or debt extinguishment costs; (ii) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (iii) distributions received from equity method investees; and (iv) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective, with retrospective adoption, for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. We anticipate that the adoption of this guidance in 2018 will result in an increase to our 2017 and 2016 operating cash flows of approximately $2 million and $3 million, respectively, reflecting adjustments for distributions received from equity method investees.



In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash ("ASU 2016-18"). ASU 2016-18, requires that restricted cash and restricted cash equivalents be included with cash and cash equivalents in the reconciliation of beginning and ending cash on the statements of cash flows. This update also requires a reconciliation of the statement of the cash flows to the balance sheet if the balance sheet includes more than one line item containing cash, cash equivalents, and restricted cash. We currently have restricted cash associated with our participation in the National Flood Insurance Program ("NFIP") within "Other assets" on our consolidating balance sheets. This restricted cash amounted to $44.2 million, $36.9 million, and $11.9 million on December 31, 2017, 2016, and 2015, respectively. ASU 2016-18 is effective, with retrospective adoption, for annual periods beginning after December 15, 2017, and interim periods within those annual periods. We anticipate that the adoption of this guidance in 2018 will result in increases to operating cash flows of $7 million and $25 million for 2017 and 2016, respectively. The restricted cash balance will also be included in the reconciliation of beginning and ending cash balances.

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other: Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 eliminates the second step of the two part goodwill impairment test, which required entities to determine the fair value of individual assets and liabilities of a reporting unit to measure the goodwill impairment. Under the new guidance, a goodwill impairment is calculated as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments in this update should be applied on a prospective basis for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We intend to adopt this guidance in 2018, but do not expect it to impact our financial condition or results of operations.

In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"). ASU 2017-07 requires that an employer report a pension plan's service cost in the same line item or line items as other compensation costs arising from services rendered by pertinent employees during the period. ASU 2017-07 also requires that other components of net benefit cost be presented in the income statement separately from the service cost component. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. ASU 2017-07 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted at the beginning of an annual period. As our pension plan was frozen as of March 2016, we have ceased accruing additional service fee costs since that time. Therefore, the application of this guidance is not anticipated to impact our financial condition, results of operations, or disclosures.

We do not currently intend to sell any of the securities in the tables above, nor dowill we believe we will be required to sell any of these securities. Additionally, we have reviewedConsidering these factors and our review of these securities in accordance withunder our OTTIcredit loss policy as described in Note 2. “Summary of Significant Accounting Policies” of this Form 10-K, andwe have concluded that they are temporarily impaired.no ACL is required on these balances. This conclusion reflects our current judgment as to the financial position and future prospects of the entity that issued the investment security and underlying collateral. If our judgment about an individual security changes in the future, we may ultimately record a credit loss after having originally concluded that one did not exist, which could have a material impact on our net income and financial position in future periods.

Western Europe.


Real Estate: This strategy invests in real estate in North America, Europe, and Asia via direct property ownership, joint ventures, mortgages, and investments in equity and debt instruments.


Our alternative investment strategies generallymay employ low or moderate levels of leverage and may use hedging only to reduce foreign exchange or interest rate volatility. At this time, our alternative investment strategies do not include hedge funds. We typically cannot redeem our investments with the general partners of these investments; however, occasionally these partnerships can be traded on the secondary market. Once liquidation is triggered by clauses within the limited partnership agreements or at the funds’ stated end date, we will receive our final allocation of capital and any earned appreciation of the underlying investments, assuming we have not divested ourselves of our partnership interests prior to that time. We currently receive distributions from these alternative investments through the realization of the underlying investments or income generated in the limited partnerships. We anticipate that the general partners of these alternative investments will liquidate their underlying investment portfolios through 2032.

In 2020, we recognized an additional allowance for credit losses of $13.5 million, net of write-offs and recoveries. We based this increase on an evaluation of the recoverability of our premiums receivable in light of (i) the billing accommodations we announced during the first quarter of 2020, and (ii) the impact of certain state regulations that provided for deferral of payments without cancellation for a period up to 90 days and increased earned but uncollected premiums. The billing accommodations included individualized payment flexibility and suspending the effect of policy cancellations, late payment notices, and late or reinstatement fees.

Note 9. Reinsurance
Our Financial Statements reflect the effects of assumed and ceded reinsurance transactions. Assumed reinsurance refers to the acceptance of certain insurance risks that other insurance entities have underwritten. Ceded reinsurance involves transferring certain insurance risks (along with the related written and earned premiums) that we have underwritten to other insurance companies that agree to share these risks. The primary purpose of ceded reinsurance is to protect the Insurance Subsidiaries from potential losses in excess of the amount that we are prepared to accept. Our major treaties covering property, property catastrophe, and casualty business are excess of loss contracts. In addition, we have an intercompany quota share (proportional) pooling arrangement and other minor quota sharereinsurance treaties.
 
As a Standard Commercial Lines and E&S Lines writer, we are subject to the Terrorism Risk Insurance Program Reauthorization Act ("TRIPRA"), which was extended by Congress to December 31, 2020.2027. TRIPRA requires private insurers and the United StatesU. S. government to share the risk of loss on future acts of terrorism certified by the U.S. Secretary of the Treasury. Under TRIPRA, each participating insurer is responsible for paying a deductible of specified losses before federal assistance is available. This deductible is based on a percentage of the prior year’s applicable Standard Commercial Lines and E&S Lines premiums. In 2018,2021, our deductible, before tax, is approximately $323$369 million. For losses above the deductible, the federal government will pay 82%80% of losses to an industry limit of $100 billion, and the insurer retains 18%20%. The federal share of losses will be reduced by 1% each year to 80% by 2020.

The Insurance Subsidiaries remain liable to policyholders to the extent that any reinsurer becomes unable to meet their contractual obligations. In addition to this direct counterparty credit risk, we have indirect counterparty credit risk as our reinsurers often enter into their own reinsurance programs, or retrocessions, as part of managing their exposure to large losses.losses and improving their financial strength ratings. The credit quality of our reinsurers is also impacted by other factors, such as their reserve adequacy, investment portfolio, regulatory capital position, catastrophe aggregations, and risk management expertise. We evaluate and monitor the financial condition of our reinsurers under voluntary reinsurance arrangements to minimize our exposure to significant losses from reinsurer insolvencies. On an ongoing basis, we review amounts outstanding, length of collection period, changes in reinsurer credit ratings,Contractual language interpretations and other relevant factorswillingness to determine collectability of reinsurance recoverables. Thepay valid claims can impact our allowance for estimated uncollectible reinsurance.

Under our reinsurance arrangements, which are prospective in nature, reinsurance premiums ceded are recorded as prepaid reinsurance and amortized over the remaining contract period in proportion to the reinsurance protection provided, or recorded periodically, as per the terms of the contract, in a direct relationship to the gross premium recording. Reinsurance recoveries are recognized as gross losses are incurred.

Direct premiums written ("DPW") increased by 4% in 2020 compared to an increase of 7% in 2019. The decline in our DPW growth rate was primarily attributable to the following:

i.Audit and endorsement premiums that decreased by $82.5 million compared to the prior year. This decrease was primarily due to lower payroll and sales exposures on the workers compensation and general liability lines of business resulting from the economic impacts of the COVID-19 pandemic and includes the impact of the $75 million accrual that was recorded in the first quarter of 2020, $24.8 million of which remained an accrual at December 31, 2020.

ii.A $19.7 million premium credit to our personal and commercial automobile policyholders. Because of the unprecedented nature of the COVID-19-related governmental directives and the associated expected short-term favorable claims frequency impact, we obtained regulatory approval during April to provide this premium credit to our personal and commercial automobile customers. The premium credit to customers with in-force policies was equivalent to 15% of their April and May premiums.

Consistent with the fluctuations in DPW, the increase in direct premiums earned in 2020 compared to 2019 was muted by the items discussed above.

Direct and ceded loss and loss expenses incurred in 2020 were primarily impacted by increased catastrophe losses. The increase was due to the severity of the storms and individual claims that met the retention for our property excess of loss treaty. Net catastrophe losses were $215.4 million in 2020 compared to $81.0 million in 2019.

information.

Our net loss and loss expense reserves increased by $104.9$183.1 million in 2017, $113.82020, $166.5 million in 2016,2019, and $60.8$171.1 million in 2015.2018. The loss and loss expense reserves are net of anticipated recoveries for salvage and subrogation claims, which amounted to $64.8$80.9 million for 2017, $64.92020, $76.7 million for 2016,2019, and $62.1$67.7 million for 2015.2018. The changesincrease in the net loss and loss expense reserves were the result of growth in exposures, anticipated loss trends, payments of claims, and normal reserve changes inherent2020 was primarily driven by increases in the uncertaintyexposure due to premium growth.

This increase in establishing reserves forour net loss and loss expense. As additional information is collected in theexpense reserves was partially offset by favorable prior year loss settlement process, reserves are adjusted accordingly. These adjustments are reflected in the Consolidated Statements of Income in the period in which such adjustments are identified. These changes could have a material impact on the results of operations of future periods when the adjustments are made.

The Insurance Subsidiaries had $39.2$72.9 million of favorable prior accident year reserve development during 2017,2020, which included $48.6$85.0 million of net favorable casualty reserve development and $9.4$12.1 million of unfavorable property development. The net favorable casualty reserve development was largely driven by the workers compensation and general liability lines of business, including products liability and excess liability. Partially offsetting this net favorable development was $36.0 million of unfavorable casualty development in the commercial auto line of business. In addition, our E&S casualty lines experienced unfavorable development of $10.0 million in 2017.



The majority of the 2017 net favorable development was attributable to accident years 2016 and prior, driven by the general liability and workers compensation lines of business. This net favorable development was partially offset by unfavorable development in accident years 2015 and 2016 attributable to our commercial auto and E&S casualty lines of business. The unfavorable development in our commercial auto line of business was driven primarily by bodily injury liability for accident years 2012 through 2016, driven by higher than expected frequency and severity.

The Insurance Subsidiaries had $65.8 million of favorable prior accident year development during 2016, which included $69.0 million of net favorable casualty development and $3.2 million of unfavorable property development. The net favorable casualty reserve development was largely driven by the workers compensation and general liability lines of business, including products liability and excess liability. Partially offsetting this net favorable development was $25.0 million of unfavorable casualty development in the commercial automobile line of business. In addition, our E&S casualty lines experienced unfavorable development of $6.0 million in 2016.

The majority of the 2016 net favorable development was attributable to accident years 2013 and prior, driven by the workers compensation and general liability lines of business. This net favorable development was partially offset by unfavorable development in accident years 2014 and 2015 attributable to our commercial auto and E&S casualty lines of business. The unfavorable development in our commercial auto line of business was driven primarily by bodily injury liability for accident years 2014 and 2015. The unfavorable development in accident year 2014 was driven by higher than expected severity, whereas accident year 2015 was driven by higher than expected frequency and severity.

The Insurance Subsidiaries had $69.0 million of favorable prior accident year development during 2015, which included $67.0 million of net favorable casualty development and $2.0 million of favorable property development. The net favorable casualty reserve development was largely driven by the workers compensation and general liability lines of business. OurWorkers compensation was impacted by continued favorable medical trends in accident years 2018 and prior, and general liability development was attributable to lower loss severities in accident years 2017 and prior. Partially offsetting this net favorable reserve development was $10 million of unfavorable casualty reserve development in the commercial auto line of business ($7.1 million net of property reserve development), driven by unfavorable reserve development on loss severities in accident years 2016 through 2019, and higher than expected frequencies in accident year 2019.

The Insurance Subsidiaries had $50.3 million of favorable prior accident year reserve development during 2019, which included $61.0 million of net favorable casualty reserve development and $10.7 million of unfavorable property reserve development. The net favorable casualty reserve development was largely driven by the workers compensation line of business, reflecting continued favorable medical trends in accident years 2017 and prior.

The Insurance Subsidiaries had $29.9 million of favorable prior accident year reserve development during 2018, which included $41.5 million of net favorable casualty reserve development and $11.6 million of unfavorable property reserve development. The net favorable casualty reserve development was largely driven by the workers compensation line of business, reflecting continued favorable medical trends in accident years 2017 and prior. Partially offsetting this net favorable reserve development was $37.5 million of unfavorable casualty reserve development in the commercial automobile line of business, driven by increases in frequencies and severities in accident years 2015 through 2017. In addition, our E&S casualty lines experienced unfavorable reserve development of $16.0$12.0 million in 2015.2018.


The majority of the 2015 net favorable development was attributable(b) We have exposure to accident years 2009 through 2013, driven by the workers compensation andabuse or molestation claims within our general liability linesline of business. This net favorable development was partially offsetbusiness through insurance policies that we issue to schools, religious institutions, daycares, and other social services. We also have exposure to abuse or molestation claims from recently enacted state laws that extend the statute of limitations or permit windows to be opened for abuse or molestation claims and lawsuits that were previously barred by unfavorable developmentstatutes of limitations. The emergence of these claims is slow and highly unpredictable. There are significant uncertainties in accident years 2012 through 2014 attributableestimating our exposure to abuse or molestation claims (for both case and IBNR reserves) resulting from (i) lack of relevant historical data, (ii) the delayed and inconsistent reporting patterns associated with these claims, (iii) the obligation of an insurer to defend a claim, (iv) the extent to which a party can prove the existence of coverage, and (v) uncertainty as to the number and identity of claimants. It is possible, as a result, that we may receive claims decades after the allegations occurred from coverages provided by us, including predecessor companies, that will require complex claims coverage determinations, potential litigation, and the need to collect from reinsurers under older reinsurance agreements. We do not discount to present value that portion of our E&S casualty lines of business.loss and loss expense reserves expected to be paid in future periods.


(b)(c) Reserves established for liability insurance include exposure to asbestos and environmental claims. These claims have arisen primarily from insured exposures in municipal government, small non-manufacturing commercial risk, and homeowners policies. The emergence of these claims is slow and highly unpredictable. There are significant uncertainties in estimating our exposure to asbestos and environmental claims (for both case and IBNR reserves) resulting from (i) lack of relevant historical data, (ii) the delayed and inconsistent reporting patterns associated with these claims, and (iii) uncertainty as to the number and identity of claimants and complex legal and coverage issues. Legal issues that arise in asbestos and environmental cases include federal or state venue, choice of law, causation, admissibility of evidence, allocation of damages and contribution among joint defendants, successor and predecessor liability, and whether direct action against insurers can be maintained.
106



Coverage issues that arise in asbestos and environmental cases include the interpretation and application of policy exclusions, the determination and calculation of policy limits, the determination of the ultimate amount of a loss, the extent to which a loss is covered by a policy, if at all, the obligation of an insurer to defend a claim, and the extent to which a party can prove the existence of coverage. Courts have reached different and sometimes inconsistent conclusions on these legal and coverage issues. We do not discount to present value that portion of our losses and

Reserves for asbestos and environmental claims are highly uncertain. There are significant uncertainties associated with estimating critical assumptions, such as average clean-up costs, third-party costs, potentially responsible party shares, allocation of damages, litigation and coverage costs, and potential state and federal legislative changes. Estimating IBNR is challenging because of the delayed and inconsistent reporting patterns associated with these claims. Traditional actuarial approachesdevelopment methods cannot be applied because past loss history is not necessarily indicative of future behavior. While certainInstead, we review the experience by calendar year and rely on alternative projection models


can be applied,metrics, such models can produce significantly different results with small changes in assumptions.as paid and incurred survival ratios. As a result, reserves for asbestos and environmental require a high degree of judgment. Because of the significant uncertainty in the estimate, we do not calculate an asbestos and environmental loss range.


The following table details our loss and loss expense reserves for various asbestos and environmental claims:

Historically, our asbestos and environmental claims have been significantly lower in volume than many other standard commercial lines carriers since, prior to the introduction of the absolute pollution exclusion endorsement in the mid-1980’s, we were primarily awrote Standard Personal Lines, carrier and therefore, do not have broadour exposure to asbestos and environmental claims. Additionally, we are the primary insurance carrier on the majority of these exposures, which provides more certainty in our reserve position compared to other insurance carriers.claims has been limited.

(c)(d) The following is information about incurred and paid claims development as of December 31, 2017,2020, net of reinsurance, as well as cumulative claim frequency and the total ofassociated IBNR liabilities. During the experience period, we implemented a series of underwriting and claims-related initiatives, andas well as, claims management changes. These initiatives focused on exiting underperforming books of business, claims handling and reserving, medical claims costs, and loss adjustment expenses. As a result of these initiatives, several historical patterns have changed and may no longer be appropriate to use as the sole basis for projections.

In addition to the above requirements, the Line of Credit agreement contains a cross-default provision that provides that the Line of Credit will be in default if we fail to comply with any condition, covenant, or agreement (including payment of principal and interest when due on any debt with an aggregate principal amount of at least $20 million), which causes or permits the acceleration of principal. Additionally, the Line of Credit limits borrowings from the FHLBI and the FHLBNY to 10% of the respective member company's admitted assets for the previous year.


Long-term Debt Activity
(1) In the first quarter of 2009, Selective Insurance Company2019, we issued $300 million of South Carolina ("SICSC")5.375% Senior Notes due 2049 at a discount of $5.9 million which, when coupled with debt issuance costs of approximately $3.3 million, resulted in net proceeds from the offering of $290.8 million. The 5.375% Senior Notes pay interest on March 1 and Selective Insurance CompanySeptember 1 of each year. The first payment was made on September 1, 2019. A portion of the Southeast ("SICSE"),proceeds from this debt issuance was used to fully redeem the $185 million aggregate principal amount of our 5.875% Senior Notes due 2043, with the remaining $106 million being used for general corporate purposes. The 5.875% Senior Notes had pre-tax debt retirement costs of $4.2 million, or $3.3 million after tax, which was recorded in Interest expense on the Consolidated Statements of Income in the first quarter of 2019. There are no financial debt covenants to which we are required to comply in regards to the 5.375% Senior Notes.

(2) In the first quarter of 2009, SICSC and SICSE, which are collectively referred to as the "Indiana Subsidiaries" as they are domiciled in Indiana, joined, and invested in, the FHLBI, which provides them with access to additional liquidity. The Indiana Subsidiaries’ aggregate investment in the FHLBI was $5.7 million at December 31, 2020 and $2.8 million at December 31, 2017 and December 31, 2016.2019. Our investment provides us the ability to borrow approximately 20 times the total amount of the FHLBI common stock purchased with additional collateral, at comparatively low borrowing rates. The proceeds from the FHLBI borrowing on December 16, 2016 of $60 million were used to repay a $45 million borrowing from the FHLBI that was outstanding at the time, with the remaining $15 million used for general corporate purposes. All borrowings from the FHLBI require security. There are no financial debt covenants to which we are required to comply with in regards to these borrowings. For information on investments that are pledged as collateral for these borrowings, see Note 5. "Investments" above.


(2)(3) In the fourth quarter of 2015, SICA and Selective Insurance Company of New York ("SICNY") joined, and invested in, the FHLBNY, which provides them with access to additional liquidity. The aggregate investment for both subsidiaries was $2.6$3.1 million at December 31, 20172020 and $2.8 million at December 31, 2016.2019. Our investment provides us the ability to borrow approximately 20 times the total amount of the FHLBNY common stock purchased with additional collateral, at comparatively low borrowing rates. In 2016, SICA borrowed the following amounts from the FHLBNY: (i) $25 million in August 2016 at an interest rate of 1.56%, which is due on August 16, 2021; and (ii) $25 million from the FHLBNYin July 2016 at an interest rate of 1.61%, which is due on July 21, 2021.

All borrowings from the FHLBNY require security. There are no financial debt covenants to which we are required to comply with in regards to these borrowings. For information on investments that are pledged as collateral for these borrowings, see Note 5. "Investments" above.

(3) In February 2013, we issued $185 million of 5.875% Senior Notes due 2043. The notes became callable by us on February 8, 2018, at a price equal to 100% of their principal outstanding amount, plus accrued and unpaid interest to, but excluding, the date of redemption. A portion of the proceeds from this debt issuance was used to fully redeem the $100 million aggregate principal amount of our 7.5% Junior Subordinated Notes due 2066. Of the remaining net proceeds, $57.1 million was used to make capital contributions to the Insurance Subsidiaries, while the balance was used for general corporate purposes. There are no financial debt covenants to which we are required to comply in regards to these Senior Notes.


(4) In November 2005, we issued $100 million of 6.70% Senior Notes due 2035. These notes were issued at a discount of $0.7 million resulting in an effective yield of 6.754%. Net proceeds of approximately $50 million were used to fund an irrevocable trust that subsequently funded certain payment obligations in respect of our outstanding debt. The remainder of the proceeds was used for general corporate purposes. The agreements covering these notes contain a standard default cross-acceleration provision that provides the 6.70% Senior Notes will enter a state of default upon the failure to pay principal when due or upon any event or condition that results in an acceleration of principal of any other debt instrument in excess of $10 million that we have outstanding concurrently with the 6.70% Senior Notes. There are no financial debt covenants to which we are required to comply in regards to these notes.


116



(5) In November 2004, we issued $50 million of 7.25% Senior Notes due 2034. These notes were issued at a discount of $0.1 million, resulting in an effective yield of 7.27%. We contributed $25 million of the bond proceeds to the Insurance Subsidiaries as capital. The remainder of the proceeds was used for general corporate purposes. The agreements covering these notes contain a standard default cross-acceleration provision that provides the 7.25% Senior Notes will enter a state of default upon the failure to pay principal when due or upon any event or condition that results in an acceleration of principal of any other debt instrument in excess of $10 million that we have outstanding concurrently with the 7.25% Senior Notes. There are no financial debt covenants to which we are required to comply in regards to these notes.




Note 11.12. Segment Information
The disaggregatedWe evaluate the results of our four4 reportable segments are used by senior management to manage our operations. These reportable segments are evaluated as follows:


Our Standard Commercial Lines, Standard Personal Lines, and E&S Lines are evaluated based on before and after-tax underwriting results (net premiums earned, incurred loss and loss expense, policyholders dividends, policy acquisition costs, and other underwriting expenses), return on equity ("ROE") contribution, and combined ratios.


Our Investments segment is primarily evaluated based on after-tax net investment income and its ROE contribution. After-tax net realized and unrealized gains and losses.losses, which are not included in non-GAAP operating income, are also included in our Investment segment results.


In computing theeach segment's results, of each segment, we do not make adjustments for interest expense or corporate expenses. We do not maintainNo segment has a separate investment portfolios for the segments and therefore, do not allocate assets to the segments.portfolio or allocated assets.


Our combined insurance operations are subject to certain geographic concentrations, particularly in the Northeast and Mid-Atlantic regionsEastern region of the country. In 2017,2020, approximately 20%18% of NPW were related to insurance policies written in New Jersey.

Note 13.14. Federal Income Taxes
(a) On December 22, 2017, the Tax Cuts and Jobs Act of 2017 ("Tax Reform") was signed into law, which among other implications, will reduce our statutory corporate tax rate from 35% to 21% beginning with our 2018 tax year. We revalued our deferred tax inventory as of December 31, 2017 in anticipation of this reduction, which resulted in a $20.2 million charge to income as illustrated in the rate reconciliation table below. This charge included a $5.7 million benefit related to net unrealized gains on our investment portfolio and pension plan, which were originally recorded through AOCI.

Our accounting for the impact of Tax Reform on our deferred tax assets and liabilities is complete with the exception of amounts related to loss reserve discounting. Prior to Tax Reform, we had elected to use our own loss reserve payment patterns in determining the factors that we use in our discounting calculation. Under Tax Reform, this election has been eliminated and we are required to use an industry experience approach that includes a discount rate based on a corporate bond yield curve for which the IRS has not yet issued any guidance. Considering this, we have recorded a $7.5 million provisional increase to our deferred tax asset that is based on the industry experience approach under the tax law that existed prior to Tax Reform. We believe this is a reasonable estimate for the elimination of the company experience method election. We have not estimated a provisional amount based on the revised Tax Reform industry experience approach. Based on a Tax Reform transition rule that allows for this type of change in accounting method to be amortized into expense over an eight-year period beginning in 2018, we have established an offsetting deferred tax liability of $7.5 million as of December 31, 2017. During 2018, we will obtain, prepare, and analyze the necessary information to complete the accounting for loss reserve discounting.

In addition to the impact of Tax Reform discussed above, our rate reconciliation for 2017 was also impacted by the $4.3 million impact of new accounting literature requiring that the tax effects of share-based compensation be recognized in the income tax provision. Previously, these amounts were recorded in additional paid-in capital. See Note 3. "Adoption of Accounting Pronouncements" for additional information regarding this literature change.

Net deferred federal income tax assets decreased by $52.9 million during 2017. As mentioned above, net deferred federal income tax assets were reduced by $20.2$33.9 million in relation to Tax Reform. In addition to this charge, net2020, which was primarily driven by a decrease in interest rates resulting in a $35.8 million increase in gross deferred assets decreased by $21.4 million resulting from additionaltax liabilities associated with unrealized gains generated during the year on our investmentfixed income securities portfolio.

After considering all evidence, both positive and negative, with respect to our federal tax loss carryback availability, expected levels of pre-tax financial statement income, and federal taxable income, we believe it is more likely than not that the existing deductible temporary differences will reverse during periods in which we generate net federal taxable income or have adequate federal carryback availability. As a result, we had no valuation allowance recognized for federal deferred tax assets at December 31, 20172020 or 2016.

As of December 31, 2017, we had federal tax net operating loss ("NOL") carryforwards of $0.3 million. These NOLs, which are subject to an annual limitation of $1.9 million, will expire between 2030 and 2031.

Stockholders' equity reflects tax benefits related to compensation expense deductions for share-based compensation awards of $23.8 million at December 31, 2017 and December 31, 2016, and $22.0 million at December 31, 2015. As mentioned above, beginning in 2017, all excess tax benefits and tax deficiencies on share-based payment awards are recognized as income2019. We do not have unrecognized tax expense or benefit on the Consolidated Statementsas of Income.December 31, 2020.

We have analyzed our tax positions in all open tax years, which as of December 31, 20172020 were 20142017 through 2016, and we2020. The 2018 tax year is currently under audit. We do not expect any material adjustments to arise out of the 2018 audit.

We believe our tax positions will more likely than not be sustained upon examination, including related appeals or litigation. In the event we had a tax position that did not meet the more likely than not criteria, any tax, interest, and penalties incurred related to such a position would be reflected in "Total federal income tax expense" on our Consolidated Statements of Income. We are not currently under a federal income tax audit for any tax year.
 
Note 14.15. Retirement Plans
(a) Selective Insurance Retirement Savings Plan (“Retirement Savings Plan”) and the Selective Insurance Company of America Deferred Compensation Plan ("Deferred Compensation Plan")
SICA offers a voluntary defined contribution 401(k) plan whichthat is available to most of our employees and is a tax-qualified retirement plan subject to the Employee Retirement Income Security Act of 1974 ("ERISA").  Expense recorded for this plan was $15.8 million in 2017, $15.0 million in 2016, and $14.1 million in 2015.


(b)ERISA.  In addition, SICA offers a Deferred Compensation Plan
SICA offers a nonqualified deferred compensation plan ("Deferred Compensation Plan") to a group of management or highly compensated employees as a method of recognizing and retaining such employees. The Deferred Compensation Plan provides these employees the opportunity to elect to defer receipt of specified portions of compensation and to have such deferred amounts deemed to be invested in specified investment options. In addition to the employee deferrals, SICA may choose to make matching contributions to some or all of the participants in this plan to the extent the participant did not receive the maximum matching or non-elective contributions permissible under the Retirement Savings Plan due to limitations under the Internal Revenue Code or the Retirement Savings Plan. ExpenseExpenses recorded for these contributions was $0.2plans were $18.6 million in 2017, $0.32020, $17.3 million in 2016,2019, and $0.2$16.2 million in 2015.2018.


(c)(b) Retirement Income Plan and Retirement Life Plan
SICA's primarySICA maintains a defined benefit pension plan, is the Retirement Income Plan for Selective Insurance Company of America (the "Pension Plan"). This qualified, noncontributory defined benefit plan is closed to new entrants and existing participants ceased accruing benefits after March 31, 2016.


In addition to the Pension Plan, SICA also sponsors the Supplemental Excess Retirement Plan (the "Excess Plan") and a life insurance benefit plan (the "Retirement Life Plan"). Both of these plans are closed to new entrants and participants in the Excess Plan ceased accruing benefits after March 31, 2016. The Retirement Life Plan does not accrue benefits and this plan applies only to retirees who terminated employment with SICA on or before March 31, 2009. These are both unfunded plans with benefit obligations as of December 31, 2017 and December 31, 2016 of $10.1 million and $9.1 million, respectively, for the Excess Plan and $6.4 million and $6.3 million, respectively, for the Retirement Life Plan. Expense recorded for the Excess Plan was $0.4 million in 2017, $0.5 million in 2016, and $0.8 million in 2015. Expense recorded for the Retirement Life Plan was $0.3 million in 2017, 2016, and 2015.

Our latest measurement date was December 31, 2017,2020, at which time we increaseddecreased our expected return on plan assets to 6.36%5.40%, reflecting a higher allocationdue to equity securities in the portfolio.lower expected returns within our longer-dated fixed income portfolio, as interest rates declined significantly year-over-year.
 
When determining the most appropriate discount rate to be used in the valuation, we consider, among other factors, our expected payout patterns of the Pension Plan's obligations as well as our investment strategy, and we ultimately select the rate that we believe best represents our estimate of the inherent interest rate at which our pension and post-retirement life benefits can be effectively settled. Effective January 1, 2016, theThe approach used to calculate the service and interest components of net periodic benefit cost for benefit plans was changed to provide a more precise measurement of service and interest costs.  Prior to 2016, we calculated these service and interest components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period.  Beginning in 2016, we elected to utilize an approach that discounts the individual expected cash flows using the applicable spot rates derived from the yield curve over the projected cash flow period. We have accountedOur discount rate decreased 65 basis points, to 2.68%, as of December 31, 2020, compared to 3.33% as of December 31, 2019, which drove the increase in the benefit obligation for this change prospectively as a change in accounting estimate.the period. The weighted average discount rate used to determine 20182021 interest cost is 3.46%was 2.06%.


Pension Plan Assets
Assets of the Pension Plan are invested to adequately support the liability associated with the Pension Plan's defined benefit obligation. Our return objective is to exceed the returns of the plan's policy benchmark, which is the return the plan would have earned if the assets were invested according to the target asset class weightings and earned index returns shown below. In 2018,2021, we will continue to phase in adjustments to the asset allocation to steadily close the gap between the duration of the assets and the duration of the liabilities, provided certain improved funding targets are achieved. Over time, the target and actual asset allocations may change based on the funded status of the Pension Plan and market return expectations.
     


The Pension Plan’s equity investments may not contain investments in any one security greater than 8% of the portfolio value without notification to our management investment committee, nor have more than 5% of the outstanding shares of any one corporation or other entity. The use of derivative instruments is permitted under certain circumstances, but shall not be used for unrelated speculative hedging or to apply leverage to portfolio positions. Within the alternative investments portfolio, some leverage is permitted as defined and limited by the partnership agreements.

The use of derivative instruments is permitted under certain circumstances for the Pension Plan portfolio, but may change over time based onnot be used for unrelated speculative purposes or to create exposures that are not permitted in the Pension Plan's investment guidelines. We currently invest in a U.S. Treasury overlay derivative strategy, within the funds in our liability hedging assets, to manage the interest rate duration mismatch between the assets and liabilities of the Pension Plan to help insulate the funded status of the plan and market return expectations.plan. Considering the impact of this derivative overlay, the liability hedging assets provide for an approximate 65% hedge against the projected benefit obligation.


The Pension Plan had no investments in the Parent’s common stock as of December 31, 20172020 or 2016.2019. For information regarding investments in funds of our related parties, refer to Note 18. "Related Party Transactions" below.


The techniques used to determine the fair value of the Pension Plan's invested assets that appear on the following page are as follows:
The long-duration fixed income mutual funds utilize a market approach wherein the quoted prices in the active market for identical assets are used.  All of the mutual funds are traded in active markets at their net asset value per share.  These investments are classified as Level 1 in the fair value hierarchy.
The investments in global equitythe equities and liability hedging funds include collective investment funds and fund of funds that utilize a market approach wherein the published prices in the active market for identical assets are used. These investments are traded at their net asset value per share. There are no restrictions as to the redemption of these investments nor do we have any contractual obligations for further investment. These investments are classified as Level 1 in the fair value hierarchy.
The investments in private equity limited partnerships are valued utilizing net asset value as a practical expedient for fair value.  These investments are not classified in the fair value hierarchy.
The investments in other private equity securities are non-publicly traded stocks and are valued by the issuer and reviewed internally. These investments are classified as Level 3 in the fair value hierarchy.
Short-term investments are carriedrecorded at cost, which approximates fair value.  Given that these investments are listed on active exchanges, coupled with their liquid nature, these investments are classified as Level 1 in the fair value hierarchy.
The deposit administration contract is carriedrecorded at cost, which approximates fair value.  Given the liquid nature of the underlying investments in overnight cash deposits and other short-term duration products, we have determined that a correlation exists between the deposit administration contract and other short-term investments, such as money market funds.  As such, this investment is classified as Level 2 in the fair value hierarchy.


For discussion regarding the levels within the fair value hierarchy, see Note 2. "Summary of Significant Accounting Policies."

In addition, refer to Note 5. "Investments" for discussion regarding the limited partnership investment strategies, excluding the middle marketsecondary private equity and direct lending strategy,strategies as these investments are currently not part of the Pension Plan. The hedge fund strategy is part of the overall private asset strategy and is only included in the Pension Plan assets. The Pension Plan invests in hedge funds with diversified exposure to a number of underlying systematic strategies that include arbitrage, macro-oriented and equity related strategies. These positions are expected to improve the risk-adjusted return of the portfolio given their lower volatility profile than public equities with returns that are generally uncorrelated to traditional asset classes over a complete market cycle.Plan's investment portfolio.

The types of awards that can be issued under each of these plans are as follows:
PlanTypes of Share-Based Payments Issued
Stock PlanQualified and nonqualified stock options, stock appreciation rights ("SARs"), restricted stock, restricted stock units ("RSUs"), stock grants, and other awards valued in whole or in part by reference to the Parent's common stock. The maximum exercise period for an option grant under this plan is 10 years from the date of the grant. Dividend equivalent units ("DEUs") are earned during the vesting period on RSU grants. The DEUs are reinvested in the Parent's common stock at fair value on each dividend payment date. The requisite service period for grants to employees under this plan is the lesser of: (i) the stated vested date, which is typically three years from issuance; or (ii) the date the employee becomes eligible to retire.
Cash PlanCash incentive units (“CIUs”). The initial dollar value of each CIU will be adjusted to reflect the percentage increase or decrease in the total shareholder return on the Parent's common stock over a specified performance period.

Fair Value Measurements
The grant date fair value of RSUs is based on the market price of our common stock on the grant date, adjusted for the present value of our expected dividend payments. The expense recognized for share-based awards is based on the number of shares or units expected to be issued at the end of the performance period and the grant date fair value.

127



The grant date fair value of each option award is estimated using the Black Scholes option valuation model ("Black Scholes"). The following are the significant assumptions used in applying Black Scholes: (i) the risk-free interest rate, which is the implied yield currently available on U.S. Treasury zero-coupon issues with an equal remaining term; (ii) the expected term, which is based on historical experience of similar awards; (iii) the dividend yield, which is determined by dividing the expected per share dividend during the coming year by the grant date stock price; and (iv) the expected volatility, which is based on the volatility of the Parent's stock price over a historical period comparable to the expected term. In applying Black Scholes, we use the weighted average assumptions illustrated in the following table:

The fair value of the CIU liability is remeasured at each reporting period through the settlement date of the awards, which is three years from the date of grant based on an amount expected to be paid. A Monte Carlo simulation is performed to approximate the projected fair value of the CIUs that, in accordance with the CIU agreements established under the Cash Plan, is adjusted to reflect our performance on specified indicators as compared to targeted peer companies.

Note 18.21. Litigation
As of December 31, 2020, we do not believe we are involved in any legal action that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

In the ordinary course of conducting business, we are named as defendantsparties in various legal proceedings.actions. Most of these proceedings are claims litigation involving our Insurance Subsidiaries as either: (i) liability insurers defending or providing indemnity for third-party claims brought against our customers; or (ii) insurers defending first-party coverage claims brought against them.them, or (iii) liability insurers seeking declaratory judgment on our insurance coverage obligations. We account for such activity through the establishment of unpaid lossesloss and loss expense reserves. WeIn ordinary course claims litigation, we expect that any potential ultimate liability, in such ordinary course claims litigationafter consideration of provisions made for potential losses and costs of defense, will not be material to our consolidated financial condition, results of operations, or cash flows after considerationflows.

All of our commercial property and businessowners' policies require direct physical loss of or damage to property by a covered cause of loss. It also is our practice to include in, or attach to, all standard lines commercial property and businessowners' policies an exclusion that states that all loss or property damage caused by or resulting from any virus, bacterium, or other microorganism that induces or is capable of inducing physical distress, illness, or disease is not a covered cause of loss ("Virus Exclusion"). Whether COVID-19 related contamination, the existence of COVID-19 pandemic, and the resulting COVID-19 related government shutdown orders cause physical loss of or damage to property is the subject of much public debate and first-party coverage litigation against some insurers, including us. The Virus Exclusion also is the subject of first-party coverage litigation against some insurers, including us.

From time to time, our Insurance Subsidiaries also are named as defendants in other legal actions, some of which assert claims for substantial amounts. ThesePlaintiffs may style these actions include, among others,as putative class actions seekingand seek judicial certification of a state or national class. Such putative class actions have alleged, for example,allegations involving our business practices, such as improper reimbursement of medical providers paid under workers compensation and personal and commercial automobile insurance policies.policies or improper reimbursement for automobile parts. Similarly, our Insurance Subsidiaries are alsocan be named from time-to-time in individual actions seeking extra-contractual damages, punitive damages, or penalties, some of which allegeoften alleging bad faith in the handling of insurance claims. We believe that we have valid defenses to these cases. Weallegations and we account for such activity through the establishment of unpaid loss and loss expense reserves. In these other legal actions, we expect that any potential ultimate liability, in any such lawsuitafter consideration of provisions made for estimated losses, will not be material to our consolidated financial condition, after consideration of provisions made for estimated losses.condition. Nonetheless, givenlitigation outcomes are inherently unpredictable and, because the inherent unpredictability of litigation and the large or indeterminate amounts sought in certain of these actions anare large or indeterminate, it is possible that any adverse outcome in certain mattersoutcomes could possibly have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods.


As of December 31, 2017, we do not believe the Company was involved in any legal action that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

Note 19.22. Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds
(a) Statutory Financial Information
The Insurance Subsidiaries prepare their statutory financial statements in accordance with accounting principles prescribed or permitted by the various state insurance departments of domicile. Prescribed statutory accounting principles include state laws, regulations, and general administrative rules, as well as a variety of publications of the National Association of Insurance Commissioners (“NAIC"). Permitted statutory accounting principles encompass all accounting principles that are not prescribed; such principles differ from state to state, may differ from company to company within a state and may change in the future. The Insurance Subsidiaries do not utilize any permitted statutory accounting principles that materially affect the determination of statutory surplus, statutory net income, or risk-based capital (“RBC”). As of December 31, 2017,2020, the various state insurance departments of domicile have adopted the March 20172020 version of the NAIC Accounting Practices and Procedures manual in its entirety, as a component of prescribed or permitted practices.

(b) Capital Requirements
The Insurance Subsidiaries are required to maintain certain minimum amounts of statutory surplus to satisfy the requirements of their various state insurance departments of domicile. RBC requirements for property and casualty insurance companies are designed to assess capital adequacy and to raise the level of protection that statutory surplus provides for policyholders. The Insurance Subsidiaries' combined total adjusted capital exceeded the authorized control level RBC, as defined by the NAIC based on their 20172020 statutory financial statements. In addition to statutory capital requirements, we are impacted by various rating agency requirements related to certain rating levels. These required capital levels may be more than statutory requirements.


(c) Restrictions on Dividends and Transfers of Funds
Our ability to declare and pay dividends on the Parent's common stock is dependent on liquidity at the Parent coupled with the ability of the Insurance Subsidiaries to declare and pay dividends, if necessary, and/or the availability of other sources of liquidity to the Parent.

In addition to regulatory restrictions on the availability of dividends that our Insurance Subsidiaries can pay to the Parent, the maximum amount of dividends the Parent can pay our shareholders is limited by certain New Jersey corporate law provisions that limit dividends if either: (i) the Parent would be unable to pay its debts as they became due in the usual course of business; or (ii) the Parent’s total assets would be less than its total liabilities.  The Parent’s ability to pay dividends to shareholders also
132



are impacted by (i) covenants in its Line of Credit that obligate it, among other things, to maintain a minimum consolidated net worth and a maximum ratio of consolidated debt to total capitalization, and (ii) the terms of our preferred stock that prohibit dividends to be declared or paid on our common stock if dividends are not declared and paid, or made payable, on all outstanding preferred stock for the latest completed dividend period.

As of December 31, 2017,2020, the Parent had an aggregate of $114.5$490.2 million in investments and cash available to fund future dividends and interest payments. These amounts are not subject to any regulatory restrictions other than the standard state insolvency restrictions noted above, whereas our consolidated retained earnings of $1.7$2.3 billion is are predominately restricted due to the regulation associated with our Insurance Subsidiaries. In 2018,2021, the Insurance Subsidiaries have the ability to provide for $211.0$241.0 million in annual dividends to the Parent; however, as regulated entities, these dividends are subject to certain restrictions, which are further discussed below. The Parent also has available to it other potential sources of liquidity, such as: (i) borrowings from our Indiana Subsidiaries; (ii) debt issuances; (iii) common and preferred stock issuances; and (iv) borrowings under our Line of Credit. Borrowings from our Indiana Subsidiaries are governed by approved intercompany lending agreements with the Parent that provide for additional capacity of $70.5$97.1 million as of December 31, 2017,2020, based on restrictions in these agreements that limit borrowings to 10% of the admitted assets of the Indiana Subsidiaries. For additional restrictions on the Parent's debt, see Note 10.11. "Indebtedness" in this Form 10-K.


Insurance Subsidiaries Dividend Restrictions
As noted above, the restriction on our net assets and retained earnings is predominantly driven by our Insurance Subsidiaries' ability to pay dividends to the Parent under applicable lawlaws and regulations. Under the insurance laws of the domiciliary states of the Insurance Subsidiaries, New Jersey, Indiana, and New York, an insurer can potentially make an ordinary dividend payment if its statutory surplus following such dividend is reasonable in relation to its outstanding liabilities, is adequate to its financial needs, and the dividend does not exceed the insurer's unassigned surplus. In general, New Jersey defines an ordinary dividend as a dividend whose fair market value, together with other dividends made within the preceding 12 months, is less than the greater of 10% of the insurer's statutory surplus as of the precedingDecember 31, or the insurer's net income (excluding capital gains) for the 12-month period ending on the preceding December 31. Indiana's ordinary dividend calculation is consistent with New Jersey's, except that it does not exclude capital gains from net income. In general, New York defines an ordinary dividend as a dividend whose fair market value, together with other dividends made within the preceding 12 months, is less than the lesser of 10% of the insurer's statutory surplus, or 100% of adjusted net investment income.


New Jersey and Indiana require notice of the declaration of any ordinary dividend distribution. During the notice period, the relevant state regulatory authority may disallow all or part of the proposed dividend if it determines that the dividend is not appropriate given the above considerations. New York does not require notice of ordinary dividends. Dividend payments


exceeding ordinary dividends are referred to as extraordinary dividends and require review and approval by the applicable domiciliary insurance regulatory authority prior to payment.
The table below provides the following table providesinformation: (i) quantitative data regarding all Insurance Subsidiaries' dividends paid to the Parent in 20172020, which was used for debt service, shareholder dividends, and general operating purposes:

Note 21. Subsequent Events
Subsequent to year-end and through the end of January 2018, our insurance operations experienced significant insured property losses, principally due to the deep freeze that impacted our footprint states during the month, the Property Claims Services ("PCS") named winter storm that occurred between January 3 and January 6, and a relatively large number of severe fire losses. For January 2018, non-catastrophe property losses amounted to $47 million and catastrophe losses, which we define as only those losses specifically attributable to a named PCS catastrophe, totaled $16 million. In total, the $63 million of insured property losses were approximately $30 million in excess of our property loss expectations for the month of January.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures are: (i) effective in recording, processing, summarizing, and reporting information on a timely basis that we are required to disclose in the reports that we file or submit under the Exchange Act; and (ii) effective in ensuring that information that we are required to disclose in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
 
Management's Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) is a process designed by, or under the supervision of, a company's principal executive and principal financial officers and effected by the Board, management and other personnel, 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 and includes those policies and procedures that:

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;
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
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.


Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2017.2020. 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 ("COSO Framework") in 2013.
 
Based on this assessment, our management believes that, as of December 31, 2017,2020, our internal control over financial reporting is effective.

Except for internal controls over financial reporting related to the October 1, 2017 implementation of a new billing system, there were noNo changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act) that occurred during the fourth quarter ended December 31, 2017of 2020 that have materially affected, or are reasonably likely to materially affect, our internal controlscontrol over financial reporting.  Management reviewed and tested the effectiveness of the internal controls over financial reporting related to the implementation of the new billing system and concluded they were effective.

Attestation Report of the Independent Registered Public Accounting Firm
Our independent registered public accounting firm, KPMG, LLP, has issued their attestation report on our internal control over financial reporting which is set forth below.

Selective Insurance Group, Inc.:
 
Opinion on Internal Control Over Financial Reporting
We have audited Selective Insurance Group, Inc. and its subsidiaries’ (the “Company”"Company") internal control over financial reporting as of December 31, 2017,2020, based on criteria established in Internal Control - Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Selective Insurance Group, Inc.’sCommission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the consolidated balance sheets of the Company as of December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2020, and the related notes and financial statement schedules I to V (collectively, the "consolidated financial statements"), and our report dated February 12, 2021 expressed an unqualified opinion on those consolidated financial statements.

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 Report on Internal Control overOver Financial Reporting.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 Public Company Accounting Oversight Board (United States).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 of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included 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.


In our opinion, Selective Insurance Group, Inc. and its subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Selective Insurance Group, Inc. and subsidiaries as of December 31, 2017 and 2016, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2017, and our report dated February 19, 2018 expressed an unqualified opinion on those consolidated financial statements.
