History and Organization | History and Organization Aspen Insurance Holdings Limited (“Aspen Holdings”) was incorporated on May 23, 2002 as a holding company headquartered in Bermuda. We underwrite specialty insurance and reinsurance on a global basis through our Operating Subsidiaries (as defined below) based in Bermuda, the United States and the United Kingdom: Aspen Insurance UK Limited (“Aspen U.K.”) and Aspen Underwriting Limited (corporate member of Lloyd’s Syndicate 4711, “AUL” and managed by Aspen Managing Agency Limited (“AMAL”)) (United Kingdom), Aspen Bermuda Limited (“Aspen Bermuda”) (Bermuda), Aspen Specialty Insurance Company (“Aspen Specialty”) and Aspen American Insurance Company (“AAIC”) (United States) (collectively, the “Operating Subsidiaries”). We also have branches in Australia, Canada, Ireland, Singapore, Switzerland and the United Arab Emirates. We established Aspen Capital Management, Ltd. and other related entities (collectively, “ACM”) to leverage our existing underwriting franchise, increase our operational flexibility in the capital markets and provide investors direct access to our underwriting expertise.

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Preparation The accompanying unaudited condensed consolidated financial statements have been prepared on the basis of generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Results for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ended December 31, 2018 . The unaudited condensed consolidated financial statements include the accounts of Aspen Holdings and its subsidiaries. All intercompany transactions and balances have been eliminated on consolidation. The balance sheet as at December 31, 2017 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2017 contained in the Company’s Annual Report on Form 10-K filed with the United States Securities and Exchange Commission (the “SEC”) on February 22, 2018 (File No. 001-31909). Assumptions and estimates made by management have a significant effect on the amounts reported within the unaudited condensed consolidated financial statements. The most significant of these assumptions and estimates relate to losses and loss adjustment expenses, reinsurance recoverables, gross written premiums and commissions which have not been reported to the Company such as those relating to proportional treaty reinsurance contracts, unrecognized tax benefits, the fair value of derivatives and the fair value of other investments. All material assumptions and estimates are regularly reviewed and adjustments made as necessary, but actual results could turn out significantly different from those expected when the assumptions or estimates were made. Accounting Pronouncements Adopted in 2018 On August 12, 2015, the FASB issued ASU 2015-14, “ Revenue from Contracts with Customers (Topic 606)” which delayed the effective date of ASU 2014-09 by one year. ASU 2015-04 is effective for annual periods beginning after December 15, 2017. Adoption of this ASU during the three months ended March 31, 2018 did not have a material impact on the Company’s consolidated financial statements as insurance contracts accounted for within the scope of Topic 944, Financial Services are exempt from this ASU and the Company has immaterial other revenue. On January 5, 2016, the FASB issued ASU 2016-1, “ Financial Instruments - Overall (Subtopic 825-10)” which enhances the reporting model for financial instruments. Included within the requirements of this ASU are the following: a) equity investments to be measured at fair value with changes in fair value recognized in net income; b) a simplification of the impairment assessment of equity investments without readily determinable fair values; c) public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; and d) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The amendments required as a result of this ASU are effective for fiscal years beginning after December 15, 2017. Adoption of this ASU during the three months ended March 31, 2018 did not have a material impact on the Company’s consolidated financial statements as the Company’s equity portfolio, prior to being sold, was classified as held for trading with changes in fair value recognized through net income and no valuation allowance was required in relation to deferred tax asset related to available-for-sale securities Other accounting pronouncements were issued during the three months ended March 31, 2018 which were either not relevant to the Company or did not impact the Company’s consolidated financial statements. Accounting Pronouncements Not Yet Adopted On February 14, 2018, the FASB issued ASU 2018-02, “ Income Statement - Reporting Comprehensive Income (Topic 220)” which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. This ASU is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The Company is currently evaluating the provisions of ASU 2018-02 to determine how it will be affected, but no material impact is expected on the consolidated financial statements. On February 28, 2018, the FASB issued ASU 2018-03, “ Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10)” which amends multiple areas in Subtopic 825-10 via improvements to clarify the Codification or to correct unintended application of guidance. This ASU is effective for fiscal years beginning after December 15, 2017 and for interim periods within those fiscal years beginning after June 15, 2018. The Company is currently evaluating the provisions of ASU 2018-03 to determine how it will be affected, but no material impact is expected on the consolidated financial statements. Other accounting pronouncements were issued during the three months ended March 31, 2018 which were either not relevant to the Company or did not impact the Company’s consolidated financial statements. |

Earnings Per Share [Abstract] | |
Earnings per Ordinary Share | Earnings per Ordinary Share Basic earnings per ordinary share are calculated by dividing net income available to holders of Aspen Holdings’ ordinary shares by the weighted average number of ordinary shares outstanding. Net income available to ordinary shareholders is calculated by deducting preference share dividends and net income/(loss) attributable to non-controlling interest from net income/ (loss) after tax for the period. Diluted earnings per ordinary share are based on the weighted average number of ordinary shares and dilutive potential ordinary shares outstanding during the period of calculation using the treasury stock method. The following table sets forth the computation of basic and diluted earnings per ordinary share for the three months ended March 31, 2018 and 2017 , respectively: Three Months Ended March 31, 2018 2017 ($ in millions, except share and per share amounts) Net income $ 30.8 $ 96.5 Preference share dividends (7.6 ) (10.5 ) Preference share redemption costs (1) — (2.4 ) Net amount attributable to non-controlling interest (0.2 ) (0.1 ) Basic and diluted net income available to ordinary shareholders $ 23.0 $ 83.5 Ordinary shares: Basic weighted average ordinary shares 59,546,165 59,862,662 Weighted average effect of dilutive securities (2) 966,982 1,334,110 Total diluted weighted average ordinary shares 60,513,147 61,196,772 Earnings per ordinary share: Basic $ 0.39 $ 1.39 Diluted (3) $ 0.38 $ 1.36 (1) The $2.4 million deduction from net income in 2017 is attributable to the reclassification from additional paid-in capital to retained earnings representing the difference between the capital raised upon issuance of the 7.401% Perpetual Non-Cumulative Preference Shares, net of issuance costs, and the final redemption costs of $133.2 million . (2) Dilutive securities consist of employee restricted share units and performance shares associated with the Company’s long-term incentive plan, employee share purchase plans and director restricted share units as described in Note 14. Dividends. On May 2, 2018, the Company’s Board of Directors (the “Board of Directors”) declared the following quarterly dividends: Dividend Payable on: Record Date: Ordinary shares $ 0.24 June 5, 2018 May 18, 2018 5.95% preference shares $ 0.3719 July 1, 2018 June 15, 2018 5.625% preference shares $ 0.3516 July 1, 2018 June 15, 2018 |

Segment Reporting [Abstract] | |
Segment Reporting | Segment Reporting The Company has two reporting business segments: Insurance and Reinsurance. The Company has determined its reportable segments, Aspen Insurance and Aspen Reinsurance, by taking into account the manner in which management makes operating decisions and assesses operating performance. Profit or loss for each of the Company’s business segments is measured by underwriting profit or loss. Underwriting profit is the excess of net earned premiums over the sum of losses and loss expenses, amortization of deferred policy acquisition costs and general and administrative expenses. Underwriting profit or loss provides a basis for management to evaluate the business segment’s underwriting performance. Reinsurance Segment. The reinsurance segment consists of property catastrophe reinsurance, other property reinsurance, casualty reinsurance and specialty insurance and reinsurance. ACM forms part of our property catastrophe reinsurance line of business as it focuses primarily on property catastrophe business through the use of alternative capital. For a more detailed description of this business segment, see Part I, Item 1, “Business — Business Segments — Reinsurance” in the Company’s 2017 Annual Report on Form 10-K filed with the SEC. Insurance Segment. The insurance segment consists of property and casualty insurance, marine, aviation and energy insurance and financial and professional lines insurance. For a more detailed description of this business segment, see Part I, Item 1 “Business — Business Segments — Insurance” in the Company’s 2017 Annual Report on Form 10-K filed with the SEC. Non-underwriting Disclosures. The Company has provided additional disclosures for corporate and other (non-operating) income and expenses. Corporate and other income and expenses include net investment income, net realized and unrealized investment gains or losses, expenses associated with managing the Group, certain strategic and non-recurring costs, changes in fair value of derivatives and changes in fair value of the loan notes issued by variable interest entities, interest expenses, net realized and unrealized foreign exchange gains or losses, and income taxes, none of which are allocated to the business segments. Corporate expenses are not allocated to the Company’s business segments as they typically do not fluctuate with the levels of premiums written and are not directly related to the Company’s business segment operations. The Company does not allocate its assets by business segment as it evaluates underwriting results of each business segment separately from the results of the Company’s investment portfolio. The following tables provide a summary of gross and net written and earned premiums, underwriting results, ratios and reserves for each of the Company’s business segments for the three months ended March 31, 2018 and 2017 : Three Months Ended March 31, 2018 Reinsurance Insurance Total ($ in millions) Underwriting Revenues Gross written premiums $ 623.5 $ 493.3 $ 1,116.8 Net written premiums 425.0 210.5 635.5 Gross earned premiums 375.0 467.6 842.6 Net earned premiums 282.5 251.0 533.5 Underwriting Expenses Losses and loss adjustment expenses 166.9 143.3 310.2 Amortization of deferred policy acquisition costs 55.9 34.9 90.8 General and administrative expenses 31.6 63.6 95.2 Underwriting income $ 28.1 $ 9.2 37.3 Corporate expenses (13.7 ) Non-operating expenses (1) (12.1 ) Net investment income 47.3 Realized and unrealized investment gains 100.6 Realized and unrealized investment losses (138.3 ) Change in fair value of loan notes issued by variable interest entities 1.0 Change in fair value of derivatives 23.5 Interest expense on long term debt (7.4 ) Net realized and unrealized foreign exchange (losses) (4.7 ) Other income 2.1 Other expenses (1.2 ) Income before tax $ 34.4 Net reserves for loss and loss adjustment expenses $ 2,823.6 $ 2,244.5 $ 5,068.1 Ratios Loss ratio 59.1 % 57.1 % 58.1 % Policy acquisition expense ratio 19.8 13.9 17.0 General and administrative expense ratio 11.2 25.3 22.7 (2) Expense ratio 31.0 39.2 39.7 Combined ratio 90.1 % 96.3 % 97.8 % (1) Non-operating expenses includes $11.8 million of expenses related to the Company’s Effectiveness and Efficiency Program.

Catastrophe Bonds. The Company has invested in catastrophe bonds with a total value of $34.8 million as at March 31, 2018 . The bonds receive quarterly interest payments based on variable interest rates with scheduled maturities ranging from 2018 to 2021. The redemption value of the bonds will adjust based on the occurrence of a covered event, such as windstorms and earthquakes in the United States, Canada, the North Atlantic, Japan or Australia. Other Investments. In January 2015, the Company established, along with seven other insurance companies, a micro-insurance venture consortium and micro-insurance incubator (“MVI”) domiciled in Bermuda. The MVI is a social impact organization that provides micro-insurance products to assist global emerging consumers. The Company’s initial investment in the MVI was $0.8 million . The Company made an additional investment of $0.1 million in the twelve months ended December 31, 2017 . On July 26, 2016, the Company purchased through its wholly-owned subsidiary, Acorn Limited, a 20% share of Bene Assicurazioni (“Bene”), an Italian-based motor insurer for a total consideration of $3.3 million . The investment is accounted for under the equity method and adjustments to the carrying value of this investment are made based on the Company’s share of capital, including share of income and expenses. On January 1, 2017, the Company purchased through its wholly-owned subsidiary, Aspen U.S. Holdings, Inc. (“Aspen U.S. Holdings”), a 49% share of Digital Risk Resources, LLC (“Digital Re”), a U.S.-based enterprise engaged in the business of developing, marketing and servicing turnkey information security and privacy liability insurance products, for a total consideration of $2.3 million . The investment is accounted for under the equity method and adjustments to the carrying value of this investment are made based on the Company’s share of capital, including share of income and expenses. On December 18, 2017, the Company acquired through its wholly-owned subsidiary, Aspen U.S. Holdings, a 23.2% share of Crop Re Services LLC (“Crop Re”), a newly formed U.S.-based subsidiary of CGB Diversified Services, Inc (“CGB DS”) in exchange for the sale of AG Logic Holdings, LLC (“AgriLogic”), the Company’s former U.S. crop insurance business. Total consideration for the sale of AgriLogic consisted of the 23.2% share of Crop Re valued at $62.5 million and cash in the amount of $5.9 million . Crop Re is responsible for directing the placement of reinsurance on behalf of CGB DS and CGB Insurance Company (“CGBIC”), an Indiana insurance company affiliate of CGB DS and an RMA licensed crop insurer. The remaining 76.8% of Crop Re is owned by CGB DS. AAIC’s primary crop insurance coverage will be run-off and AAIC, or an affiliate of AAIC, will provide quota share reinsurance to CGBIC for both federal and state regulated crop insurance as part of Aspen’s ownership in Crop Re. The investment in Crop Re represents the Company’s share of the net assets of Crop Re plus the difference between the cost of the investment and the amount of underlying equity in net assets, the basis difference. The Company has determined that this basis difference of $62.5 million represents the value attributable to the ability of Crop Re to direct the placement of reinsurance business under the reinsurance commitment contained within the operating agreement between Crop Re and the Company. The investment in Crop Re is accounted for under the equity method and adjustments to the carrying value of this investment are made based on the Company’s share of capital, including share of income and expenses.

Variable Interest Entities | Variable Interest Entities As at March 31, 2018 , the Company had investments in two variable interest entities (“VIE”): Peregrine Reinsurance Ltd (“Peregrine”) and Silverton Re Ltd (“Silverton”). Peregrine. In November 2016, Peregrine, a subsidiary of the Company, was registered as a segregated accounts company under the Segregated Accounts Companies Act 2000, as amended. As at March 31, 2018 , Peregrine had four segregated accounts which were funded by a third party investor. The segregated accounts have not been consolidated as part of the Company’s consolidated financial statements. The Company has, however, determined that Peregrine has the characteristics of a VIE as addressed by the guidance in ASC 810, Consolidation . The Company concluded that it is not the primary beneficiary of the four segregated accounts of Peregrine but is the primary beneficiary of the Peregrine general fund and, similar to prior reporting periods, the Company has included the results of the Peregrine general fund in its consolidated financial statements. The Company’s exposure to Peregrine’s general fund is not material. Silverton. On September 10, 2013, the Company established Silverton, a Bermuda domiciled special purpose insurer formed to provide additional collateralized capacity to support Aspen Re’s business through retrocession agreements which are collateralized and funded by Silverton through the issuance of one or more series of participating loan notes (collectively, the “Loan Notes”). Silverton is a non-rated insurer and the risks are fully collateralized by way of funds held in trust for the benefit of Aspen Bermuda and Aspen U.K., the ceding reinsurers. All proceeds from the issuance of the Loan Notes were deposited into separate collateral accounts for each series of Loan Notes to fund Silverton’s obligations under a retrocession property quota share agreement entered into with Aspen Bermuda or Aspen Bermuda and Aspen U.K, as the case may be. The holders of the Loan Notes participate in any profit or loss generated by Silverton attributable to the operations of the respective Silverton segregated account. Any existing value of the Loan Notes will be returned to the noteholders in installments after the expiration of the risk period of the retrocession agreement issued by Silverton for the related series of Loan Notes with the final payment being contractually due on the respective maturity dates. The following tables show the total liability balance of the Loan Notes for the three months ended March 31, 2018 and 2017 : For the Three Months Ended March 31, 2018 Third Party Aspen Holdings Total ($ in millions) Opening balance $ 86.6 $ 20.6 $ 107.2 Total change in fair value for the period (1.0 ) (0.3 ) (1.3 ) Total distributed in the period (45.8 ) (10.7 ) (56.5 ) Closing balance as at March 31, 2018 $ 39.8 $ 9.6 $ 49.4 Liability Loan notes (long-term liabilities) $ 32.2 $ 7.7 $ 39.9 Accrued expenses (current liabilities) 7.6 1.9 9.5 Total aggregate unpaid balance as at March 31, 2018 $ 39.8 $ 9.6 $ 49.4 For the Three Months Ended March 31, 2017 Third Party Aspen Holdings Total ($ in millions) Opening balance $ 223.4 $ 54.5 $ 277.9 Total change in fair value for the period 2.9 0.7 3.6 Total distributed in the period (111.2 ) (28.3 ) (139.5 ) Closing balance as at March 31, 2017 $ 115.1 $ 26.9 $ 142.0 Liability Loan notes (long-term liabilities) $ 110.2 $ 26.9 $ 137.1 Accrued expenses (current liabilities) 4.9 — 4.9 Total aggregate unpaid balance as at March 31, 2017 $ 115.1 $ 26.9 $ 142.0 The Company has determined that Silverton has the characteristics of a VIE that are addressed by the guidance in ASC 810, Consolidation . The Company concluded that it is the primary beneficiary of Silverton as it owns all of Silverton’s voting shares and issued share capital, and has a significant financial interest and the power to control Silverton. As a result, the Company consolidated Silverton upon its formation. The Company has no other obligation to provide financial support to Silverton and neither the creditors nor beneficial interest holders of Silverton have recourse to the Company’s general credit. In the event of an extreme catastrophic property reinsurance event or severe credit-related event, there is a risk that Aspen Bermuda and Aspen U.K. would be unable to recover losses from Silverton. These two risks are mitigated as follows: i. Silverton has collateralized the aggregate limit provided to Aspen Bermuda and Aspen U.K. by way of a trust in favor of Aspen Bermuda and Aspen U.K. as beneficiaries; ii. the trustee is a large, well-established regulated entity; and iii. all funds within the trust account are bound by investment guidelines restricting investments to one of the institutional class money market funds run by large international investment managers.

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements The Company’s estimates of fair value for financial assets and liabilities are based on the framework established in the fair value accounting guidance included in ASC 820, Fair Value Measurements and Disclosures . The framework prioritizes the inputs, which refer broadly to assumptions market participants would use in pricing an asset or liability, into three levels. The Company considers prices for actively traded securities to be derived based on quoted prices in an active market for identical assets, which are Level 1 inputs in the fair value hierarchy. The majority of these securities are valued using prices supplied by index providers. The Company considers prices for other securities that may not be as actively traded which are priced via pricing services, index providers, vendors and broker-dealers, or with reference to interest rates and yield curves, to be derived based on inputs that are observable for the asset, either directly or indirectly, which are Level 2 inputs in the fair value hierarchy. The majority of these securities are also valued using prices supplied by index providers. The Company considers securities, other financial instruments and derivative insurance contracts subject to fair value measurement whose valuation is derived by internal valuation models to be based largely on unobservable inputs, which are Level 3 inputs in the fair value hierarchy. The following tables present the level within the fair value hierarchy at which the Company’s financial assets and liabilities are measured on a recurring basis as at March 31, 2018 and December 31, 2017 : As at March 31, 2018 Level 1 Level 2 Level 3 Total ($ in millions) Available for sale financial assets, at fair value U.S. government $ 1,292.2 $ — $ — $ 1,292.2 U.S. agency — 52.7 — 52.7 Municipal — 47.6 — 47.6 Corporate — 2,446.2 — 2,446.2 Non-U.S. government-backed corporate — 97.8 — 97.8 Non-U.S. government 338.0 145.4 — 483.4 Asset-backed — 18.5 — 18.5 Agency mortgage-backed — 973.8 — 973.8 Total fixed income securities available for sale, at fair value 1,630.2 3,782.0 — 5,412.2 Short-term investments available for sale, at fair value 52.5 2.1 — 54.6 Held for trading financial assets, at fair value U.S. government 141.7 — — 141.7 Municipal — 74.3 — 74.3 Corporate — 1,003.6 — 1,003.6 Non-U.S. government-backed corporate — 1.0 — 1.0 Non-U.S. government 49.7 166.9 — 216.6 Asset-backed — 8.3 — 8.3 Agency mortgage-backed — 192.1 — 192.1 Total fixed income securities trading, at fair value 191.4 1,446.2 — 1,637.6 Short-term investments trading, at fair value 23.3 3.7 — 27.0 Equity investments trading, at fair value — — — — Catastrophe bonds trading, at fair value — 34.8 — 34.8 Other financial assets and liabilities, at fair value Derivatives at fair value — foreign exchange contracts — 15.6 — 15.6 Liabilities under derivative contracts — foreign exchange contracts — (2.3 ) — (2.3 ) Loan notes issued by variable interest entities, at fair value — — (32.2 ) (32.2 ) Loan notes issued by variable interest entities, at fair value (included within accrued expenses and other payables) — — (7.6 ) (7.6 ) Total $ 1,897.4 $ 5,282.1 $ (39.8 ) $ 7,139.7 Transfers of assets into or out of a particular level are recorded at their fair values as of the end of each reporting period, consistent with the date of the determination of fair value. There were no transfers between Level 1, Level 2 and Level 3 during the three months ended March 31, 2018 . The Company settled $45.8 million of Level 3 liabilities in respect of the Loan Notes issued by Silverton for the three months ended March 31, 2018 . As at March 31, 2018 , there were no assets classified as Level 3 and the Company’s Level 3 liabilities consisted solely of the Loan Notes issued by Silverton.

During the twelve months ended December 31, 2017 , there were no transfers between Level 1, 2 and 3. The Company settled $115.6 million Level 3 liabilities in respect of the Loan Notes issued by Silverton for the twelve months ended December 31, 2017 . As at December 31, 2017 , there were no assets classified as Level 3 and the Company’s Level 3 liabilities consisted of the Loan Notes issued by Silverton. The following table presents a reconciliation of the beginning and ending balances for all assets and liabilities measured at fair value on a recurring basis using Level 3 inputs for the three months ended March 31, 2018 and 2017 : Reconciliation of Liabilities Using Level 3 Inputs Three Months Ended March 31, 2018 Three Months Ended March 31, 2017 ($ in millions) Balance at the beginning of the period $ 86.6 $ 223.4 Distributed to third party (45.8 ) (111.2 ) Total change in fair value included in the statement of operations (1.0 ) 2.9 Balance at the end of the period (1) $ 39.8 $ 115.1 (1) The amount classified within accrued expenses and other payables was $7.6 million and $4.9 million as at March 31, 2018 and March 31, 2017 , respectively. Valuation of Fixed Income Securities . The Company’s fixed income securities are classified as either available for sale or trading and carried at fair value. As at March 31, 2018 and December 31, 2017 , the Company’s fixed income securities were valued by pricing services, index providers or broker-dealers using standard market conventions. The market conventions utilize market quotations, market transactions in comparable instruments and various relationships between instruments including, but not limited to, yield to maturity, dollar prices and spread prices in determining value. Independent Pricing Services and Index Providers. The underlying methodology used to determine the fair value of securities in the Company’s available for sale and trading portfolios by the pricing services and index providers the Company uses is very similar. Pricing services will gather observable pricing inputs from multiple external sources, including buy and sell-side contacts and broker-dealers, in order to develop their internal prices. Index providers are those firms which provide prices for a range of securities within one or more asset classes, typically using their own in-house market makers (traders) as the primary pricing source for the indices, although ultimate valuations may also rely on other observable data inputs to derive a dollar price for all index-eligible securities. Index providers without in-house trading desks will function similarly to a pricing service in that they will gather their observable pricing inputs from multiple external sources. All prices for the Company’s securities attributed to index providers are for an individual security within the respective indices. Pricing services and index providers provide pricing for less complex, liquid securities based on market quotations in active markets. Pricing services and index providers supply prices for a broad range of securities including those for actively traded securities, such as Treasury and other Government securities, in addition to those that trade less frequently or where valuation includes reference to credit spreads, pay down and pre-pay features and other observable inputs. These securities include Government Agency, Municipals, Corporate and Asset-Backed Securities. For securities that may trade less frequently or do not trade on a listed exchange, these pricing services and index providers may use matrix pricing consisting of observable market inputs to estimate the fair value of a security. These observable market inputs include: reported trades, benchmark yields, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data, and industry and economic factors. Additionally, pricing services and index providers may use a valuation model such as an option adjusted spread model commonly used for estimating fair values of mortgage-backed and asset-backed securities. Neither the Company, nor its index providers, derives dollar prices using an index as a pricing input for any individual security. Broker-Dealers. The Company obtains quotes from broker-dealers who are active in the corresponding markets when prices are unavailable from independent pricing services or index providers. Generally, broker-dealers value securities through their trading desks based on observable market inputs. Their pricing methodologies include mapping securities based on trade data, bids or offers, observed spreads and performance of newly issued securities. They may also establish pricing through observing secondary trading of similar securities. The Company obtains prices for all of its fixed income investment securities via its third-party accounting service provider, and in the majority of cases receiving a number of quotes so as to obtain the most comprehensive information available to determine a security’s fair value. A single valuation is applied to each security based on the vendor hierarchy maintained by the Company’s third-party accounting service provider. As at March 31, 2018 and December 31, 2017 , the Company obtained an average of 2.0 quotes per fixed income investment. Pricing sources used in pricing fixed income investments as at March 31, 2018 and December 31, 2017 were as follows: As at March 31, 2018 As at December 31, 2017 Index providers 84 % 84 % Pricing services 10 11 Broker-dealers 6 5 Total 100 % 100 % Summary Pricing Information Table. A summary of securities priced using pricing information from index providers as at March 31, 2018 and December 31, 2017 is provided below: As at March 31, 2018 As at December 31, 2017 Fair Market Value Determined using Prices from Index Providers % of Total Fair Value by Security Type Fair Market Value Determined using Prices from Index Providers % of Total Fair Value by Security Type ($ in millions, except for percentages) U.S. government $ 1,433.9 100 % $ 1,321.3 100 % U.S. agency 44.4 84 % 43.4 83 % Municipal 74.7 61 % 37.4 43 % Corporate 3,275.2 95 % 3,299.6 83 % Non-U.S. government-backed corporate 42.9 43 % 44.0 48 % Non-U.S. government 373.6 53 % 399.4 58 % Asset-backed 12.7 47 % 13.5 37 % Agency mortgage-backed 630.2 54 % 605.0 53 % Total fixed income securities $ 5,887.6 84 % $ 5,763.6 84 % Equities — — % 491.0 100 % Total fixed income securities and equity investments $ 5,887.6 84 % $ 6,254.6 85 % The Company, in conjunction with its third-party accounting service provider, obtains an understanding of the methods, models and inputs used by the third-party pricing service and index providers to assess the ongoing appropriateness of vendors’ prices. The Company and its third-party accounting service provider also have controls in place to validate that amounts provided represent fair values. Processes to validate and review pricing include, but are not limited to: • quantitative analysis (e.g., comparing the quarterly return for each managed portfolio to its target benchmark, with significant differences identified and investigated); • comparison of market values obtained from pricing services, index providers and broker-dealers against alternative price sources for each security where further investigation is completed when significant differences exist for pricing of individual securities between pricing sources; • initial and ongoing evaluation of methodologies used by outside parties to calculate fair value; and • comparison of the fair value estimates to the Company’s knowledge of the current market. Prices obtained from pricing services, index providers and broker-dealers are not adjusted by us; however, prices provided by a pricing service, index provider or broker-dealer in certain instances may be challenged based on information available from market or internal sources, including those available to the Company’s third-party investment accounting service provider. Subsequent to any challenge, revisions made by the pricing service, index provider or broker-dealer to the quotes are supplied to the Company’s investment accounting service provider. Management reviews the vendor hierarchy maintained by the Company’s third-party accounting service provider in order to determine which price source provides the most appropriate fair value (i.e., a price obtained from a pricing service with more seniority in the hierarchy will be used over a less senior one in all cases). The hierarchy level assigned to each security in the Company’s available for sale and trading portfolios is based upon its assessment of the transparency and reliability of the inputs used in the valuation as of the measurement date. The hierarchy of index providers and pricing services is determined using various qualitative and quantitative points arising from reviews of the vendors conducted by the Company’s third-party accounting service provider. Vendor reviews include annual onsite due diligence meetings with index providers and pricing services vendors covering valuation methodology, operational walkthroughs and legal and compliance updates. Index providers are assigned the highest priority in the pricing hierarchy due primarily to availability and reliability of pricing information. Fixed Income Securities . The Company’s fixed income securities are traded on the over-the-counter (“OTC”) market based on prices provided by one or more market makers in each security. Securities such as U.S. Government, U.S. Agency, Non-U.S. Government and investment grade corporate bonds have multiple market makers in addition to readily observable market value indicators such as expected credit spread, except for Treasury securities, over the yield curve. The Company uses a variety of pricing sources to value fixed income securities including those securities that have pay down/prepay features such as mortgage-backed securities and asset-backed securities in order to ensure fair and accurate pricing. The fair value estimates for the investment grade securities in the Company’s portfolio do not use significant unobservable inputs or modeling techniques. U.S. Government and Agency. U.S. government and agency securities consist primarily of bonds issued by the U.S. Treasury and corporate debt issued by agencies such as the Federal National Mortgage Association (“FNMA”), the Federal Home Loan Mortgage Corporation (“FHLMC”) and the Federal Home Loan Bank. As the fair values of U.S. Treasury securities are based on unadjusted market prices in active markets, they are classified within Level 1. The fair values of U.S. government agency securities are priced using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of U.S. government agency securities are classified within Level 2. Municipals. The Company’s municipal portfolio comprises bonds issued by U.S. domiciled state and municipality entities. The fair value of these securities is determined using spreads obtained from broker-dealers, trade prices and the new issue market which are Level 2 inputs in the fair value hierarchy. Consequently, these securities are classified within Level 2. Foreign Government. The issuers for securities in this category are non-U.S. governments and their agencies. The fair values of certain non-U.S. government bonds, primarily sourced from international indices, are based on unadjusted market prices in active markets and are therefore classified within Level 1. The remaining non-U.S government bonds are classified within Level 2 as they are not actively traded. The fair values of the non-U.S. agency securities, again primarily sourced from international indices, are priced using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of non-U.S. agency securities are classified within Level 2. In addition, foreign government securities include a portion of the Emerging Market Debt (“EMD”) portfolio which is also classified within Level 2. Corporate. Corporate securities consist primarily of U.S. and foreign corporations covering a variety of industries and are for the most part priced by index providers and pricing vendors. Some issuers may participate in government programs which guarantee timely payment of principal and interest in the event of a default. The fair values of these securities are generally determined using the spread above the risk-free yield curve. Inputs used in the evaluation of these securities include credit data, interest rate data, market observations and sector news, broker-dealer quotes and trade volumes. In addition, corporate securities include a portion of the EMD portfolio. The Company classifies all of these securities within Level 2. Mortgage-backed Securities. The Company’s residential and commercial mortgage-backed securities consist of bonds issued by the Government National Mortgage Association, the FNMA and the FHLMC as well as private non-agency issuers. The fair values of these securities are determined through the use of a pricing model (including Option Adjusted Spread) which uses prepayment speeds and spreads to determine the appropriate average life of the mortgage-backed security. These spreads are generally obtained from broker-dealers, trade prices and the new issue market. As the significant inputs used to price mortgage-backed securities are observable market inputs, these securities are classified within Level 2. Asset-backed Securities. The underlying collateral for the Company’s asset-backed securities consists mainly of student loans, automobile loans and credit card receivables. These securities are primarily priced by index providers and pricing vendors. Inputs to the valuation process include broker-dealer quotes and other available trade information, prepayment speeds, interest rate data and credit spreads. The Company classifies these securities within Level 2. Short-term Investments. Short-term investments comprise highly liquid debt securities with a maturity greater than three months but less than one year from the date of purchase. Short-term investments are valued in a manner similar to the Company’s fixed income investments and are classified within Levels 1 and 2. Catastrophe Bonds. Catastrophe bonds held by the Company are variable rate fixed income instruments with redemption values adjusted based on the occurrence of a covered event, usually windstorms and earthquakes. These bonds have been classified as trading and carried at fair value. Bonds are priced using an average of multiple broker-dealer quotes and, as such, are classified as Level 2. Foreign Exchange Contracts. The foreign exchange contracts which the Company uses to mitigate currency risk are characterized as OTC due to their customized nature and the fact that they do not trade on a major exchange. These instruments trade in a deep liquid market, providing substantial price transparency and accordingly are classified as Level 2. Loan Notes Issued by Silverton . Silverton, a licensed special purpose insurer, is consolidated into the Company’s accounts as a VIE. In the fourth quarter of 2014, Silverton issued an additional $85.0 million ( $70.0 million third-party funded) of Loan Notes with a maturity date of September 18, 2017. In the fourth quarter of 2015, Silverton issued an additional $125.0 million ( $100.0 million third-party funded) of Loan Notes with a maturity date of September 17, 2018. In the fourth quarter of 2016, Silverton issued an additional $130.0 million ( $105.0 million third-party funded) of Loan Notes with a maturity date of September 16, 2019. The Company elected to account for the Loan Notes at fair value using the guidance as prescribed under ASC 825, Financial Instruments as the Company believes it represents the most meaningful measurement basis for these liabilities. The Loan Notes are recorded at fair value at each reporting period and, as they are not quoted on an active market and contain significant unobservable inputs, they have been classified as a Level 3 instrument in the Company’s fair value hierarchy. The Loan Notes are unique because they are linked to the specific risks of the Company’s property catastrophe book. To determine the fair value of the Loan Notes the Company runs an internal model which considers the seasonality of the risk assumed under the retrocessional agreement between Aspen Bermuda or a combination of Aspen Bermuda and Aspen U.K., as ceding reinsurers, and Silverton. The seasonality used in the model is initially determined by applying the percentage of property catastrophe losses planned by the Company’s actuaries to the estimated written premium to determine earned premium for each quarter. The inputs to the internal model are based on Company specific data due to the lack of observable market inputs. Reserves for losses are the most significant unobservable input. An increase in reserves for losses would normally result in a decrease in the fair value of the Loan Notes while a decrease in reserves would normally result in an increase in the fair value of the Loan Notes. The observable and unobservable inputs used to determine the fair value of the Loan Notes as at March 31, 2018 and December 31, 2017 are presented in the tables below: As at March 31, 2018 Fair Value Level 3 Valuation Method Observable (O) and Unobservable (U) inputs Low High ($ in millions) ($ in millions) Loan Notes $ 39.8 (1) Internal Valuation Model Gross premiums written (O) $ 50.1 $ 61.1 Reserve for losses (U) $ 4.2 $ 64.5 Contract period (O) N/A 365 days Initial value of issuance (O) $ 325.0 $ 325.0 As at December 31, 2017 Fair Value Level 3 Valuation Method Observable (O) and Unobservable (U) inputs Low High ($ in millions) ($ in millions) Loan Notes $ 86.6 (1) Internal Valuation Model Gross premiums written (O) $ 50.1 $ 61.1 Reserve for losses (U) $ 4.2 $ 61.9 Contract period (O) N/A 365 days Initial value of issuance (O) $ 325.0 $ 325.0 (1) The amounts classified within accrued expenses and other payables were $7.6 million and $42.4 million as at March 31, 2018 and December 31, 2017 , respectively. The observable and unobservable inputs represent the potential variation around the inputs used in the internal model. The contract period is defined in the respective Loan Notes agreements and the initial value represents the funds received from third parties.

Insurance [Abstract] | |
Reinsurance | Reinsurance The Company purchases retrocession and reinsurance to limit and diversify the Company’s risk exposure and increase its own insurance and reinsurance underwriting capacity. These agreements provide for recovery of a portion of losses and loss adjustment expenses from reinsurers. As is the case with most reinsurance contracts, the Company remains liable to the extent that reinsurers do not meet their obligations under these agreements and therefore, in line with its risk management objectives, the Company evaluates the financial condition of its reinsurers and monitors concentrations of credit risk. The total amount recoverable by the Company from reinsurers as at March 31, 2018 was $1,611.3 million ( December 31, 2017 — $1,515.2 million ) of which $1,119.8 million was uncollateralized ( December 31, 2017 — $1,001.9 million ). As at March 31, 2018 17.9% ( December 31, 2017 — 17.0% ) of the Company's uncollateralized reinsurance recoverables were with Munich Re which is rated A+ by A.M Best and AA- by S&P, 12.5% ( December 31, 2017 — 13.8% ) with Lloyd’s Syndicates which are rated A by A.M Best and A+ by S&P and 7.9% ( December 31, 2017 — 7.6% ) with Aioi Nissay Dowa Insurance Co which is rated A+ by A.M best and S&P. These are the Company’s largest exposures to individual reinsurers. The Company has made no provision for doubtful debts from any of its reinsurers as at March 31, 2018 . |

The Company uses foreign exchange contracts to manage foreign currency risk. A foreign exchange contract involves an obligation to purchase or sell a specified currency at a future date at a price set at the time of the contract. Foreign exchange contracts will not eliminate fluctuations in the value of the Company’s assets and liabilities denominated in foreign currencies but rather allow it to establish a rate of exchange for a future point in time. As at March 31, 2018 , the Company held foreign exchange contracts that were not designated as hedging under ASC 815 with an aggregate notional value of $1,109.7 million ( December 31, 2017 — $751.6 million ). The foreign exchange contracts are recorded as derivatives at fair value with changes recorded as a change in fair value of derivatives in the statement of operations. For the three months ended March 31, 2018 , the impact of foreign exchange contracts on net income was a gain of $23.5 million ( March 31, 2017 — gain of $3.1 million ). As at March 31, 2018 , the Company held foreign exchange contracts that were designated as hedging under ASC 815 with an aggregate nominal amount of $80.8 million ( December 31, 2017 — $60.6 million ). The foreign exchange contracts are recorded as derivatives at fair value in the balance sheet with the effective portion recorded in other comprehensive income and the ineffective portion recorded as a change in fair value of derivatives in the statement of operations. The contracts are considered to be effective and therefore the movement in other comprehensive income representing the effective portion for the three months ended March 31, 2018 was a net unrealized gain of $0.9 million ( March 31, 2017 — gain of $1.3 million ). As the foreign exchange contracts settle, the realized gain or loss is reclassified from other comprehensive income into general, administration and corporate expenses of the statement of operations and other comprehensive income. For the three months ended March 31, 2018 , the amount recognized within general, administrative and corporate expenses for settled foreign exchange contracts was a realized gain of $1.7 million ( March 31, 2017 — gain of $0.3 million ). |

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
Share-Based Payments | Share-Based Payments The Company has issued options and other equity incentives under three arrangements: the employee share incentive plan, the employee share purchase plans and the non-employee director stock incentive plan. When options are exercised or other equity awards (excluding phantom shares) vest, new ordinary shares are issued as the Company does not hold treasury shares. Phantom shares are settled in cash in lieu of ordinary shares upon vesting. (a) Employee Equity Incentives The total number of ordinary shares that may be issued under the Company's 2013 Share Incentive Plan is 2,845,683 ordinary shares, which includes 595,683 ordinary shares available to grant under the 2003 Share Incentive Plan as of February 25, 2013. The number of ordinary shares that may be issued under the 2013 Share Incentive Plan is adjusted per the number of awards that may be forfeited under the 2003 Share Incentive Plan. Restricted Share Units. Restricted share units (“RSUs”) granted to employees typically vest over a three -year period subject to the employee's continued service. RSUs vest granted to employees vest on the anniversary of the date of grant or when the Compensation Committee of the Board of Directors agrees to deliver them. Holders of RSUs will be paid one ordinary share for each RSU that vests as soon as practicable following the vesting date. Holders of RSUs generally will not be entitled to any rights of a holder of ordinary shares, including the right to vote, unless and until their RSUs vest and ordinary shares are issued but they are entitled to receive dividend equivalents. Dividend equivalents are denominated in cash and paid in cash if and when the underlying RSUs vest. The fair value of the RSUs is based on the closing price on the date of the grant less a deduction for illiquidity, and is expensed through the income statement evenly over the vesting period. In the three months ended March 31, 2018 , the Company granted 221,943 RSUs ( 2017 — 174,711 ) to its employees. Compensation costs charged against income in respect of RSUs granted to employees for the three months ended March 31, 2018 were $2.1 million ( 2017 — $2.5 million ). The total tax credit recognized by the Company in relation to RSUs in the three months ended March 31, 2018 was $0.2 million ( 2017 — $0.6 million ). Performance Shares. Performance share awards are subject to a three -year service vesting period with a separate annual growth in diluted BVPS test for each calendar year during the vesting period. Accordingly, one-third of the award may be earned in each calendar year. Performance share awards are not entitled to dividends before they vest and are subject to the employee’s continued employment. If performance goals are achieved, the performance shares will vest up to a maximum of 200% of target. Notwithstanding the vesting criteria for each given year, if in any given year the shares eligible for vesting are greater than 100% or the portion of such year’s grant and the average diluted BVPS growth over such year and the preceding year is less than the average of the minimum vesting thresholds for such year and the preceding year, then only 100% (and no more) of the shares that are eligible for vesting in such year shall vest. Notwithstanding the foregoing, if in the judgment of the Compensation Committee the main reason for the BVPS metric in the earlier year falling below the minimum threshold is due to the impact of rising interest rates and bond yields, then the Compensation Committee may, in its discretion, disapply the limitation on 100% vesting. During the three months ended March 31, 2018 , the Company granted 215,273 performance shares to its employees ( 2017 — 206,073 ). The fair value of performance share awards is based on the value of the closing ordinary share price on the date of the grant less a deduction for illiquidity and expected dividends which would not accrue during the vesting period. Net compensation costs charged against income in the three months ended March 31, 2018 in respect of performance shares were $2.0 million ( 2017 — $2.7 million ). The total tax recognized by the Company in relation to performance shares in the three months ended March 31, 2018 was a tax credit of $0.3 million ( 2017 — $0.5 million credit, excluding excess tax benefits. Phantom Shares. Phantom share awards are subject to a three -year service vesting period with a separate annual growth in diluted BVPS test for each calendar year during the vesting period. One-third of the award may be earned in each calendar year with the vested amount being paid in cash in lieu of ordinary shares. As ordinary shares are not issued, phantom shares have no dilutive effect. During the three months ended March 31, 2018 , the Company granted 150,185 phantom shares to its employees ( 2017 — 174,284 ). The fair value of the phantom shares is based on the closing share price on the date of the grant less a deduction for illiquidity. The fair value is expensed through the consolidated income statement evenly over the vesting period. As the payment to beneficiaries will ultimately be in cash rather than ordinary shares, an adjustment is required each quarter to revalue the accumulated liability to the balance sheet date fair value. Compensation costs charged against income in the three months ended March 31, 2018 in respect of phantom shares were $1.1 million ( 2017 — $2.2 million ). The total tax recognized by the Company in relation to phantom shares in the three months ended March 31, 2018 was $0.2 million ( 2017 — $0.4 million ), excluding excess tax benefits. Vesting Criteria Performance and Phantom Shares. Both performance share and phantom share awards are subject to a three - year vesting period with a separate BVPS growth test each year, adjusted to add back ordinary shares and movements in AOCI to shareholders’ equity at the end of the relevant year. One-third of the grant will be eligible for vesting each year based on a formula and will only be issuable at the end of the three -year period. (b) Employee Share Purchase Plans Employee Share Purchase Plans. On April 30, 2008, the shareholders of the Company approved the Employee Share Purchase Plan, the 2008 Sharesave Scheme and the International Employee Share Purchase Plan (collectively, the “ESPP”), which are implemented by a series of consecutive offering periods as determined by the Board of Directors. In respect of the ESPP, employees can save up to $500 per month over a two -year period, at the end of which they are eligible to purchase the Company’s ordinary shares at a discounted price. In respect of the 2008 Sharesave Scheme, employees can save up to £500 per month over a three -year period, at the end of which they are eligible to purchase the Company’s ordinary shares at a discounted price. Employees can purchase the Company’s ordinary shares at a discounted price equivalent to eighty-five percent ( 85% ) of the fair market value of the ordinary shares on the offering date which may be adjusted upon changes in capitalization of the Company. Under the ESPP, 4,797 ordinary shares were exercised and issued during the three months ended March 31, 2018 ( 2017 — 2,310 ). Compensation costs charged against income in the three months ended March 31, 2018 in respect of the ESPP were $0.2 million ( 2017 — $0.2 million ). The total tax credit recognized by the Company in relation to the ESPP in the three months ended March 31, 2018 was $ Nil ( 2017 — $ Nil ). (c) Non-Employee Director Plan On April 21, 2016, the shareholders of the Company approved the 2016 Stock Incentive Plan for Non-Employee Directors which provides for the granting of options, restricted share units or other share-based awards. The total number of ordinary shares that may be issued under the 2016 Non-Employee Director Plan is 263,695 . Restricted Share Units. RSUs granted to non-employee directors, including the Chairman, vest one-twelfth on each one month anniversary of the date of grant with 100% of the restricted share units becoming vested and issued on the first anniversary of the grant date or on the date of departure of a director for the amount vested through such date. The shares that are eligible to vest following final vesting date in the calendar year of the date of grant is delivered as soon as practical thereafter and the remaining shares under the RSUs are delivered on the first anniversary of the grant date. If a director leaves the Board of Directors for any reason other than “cause” (as defined in the award agreement), then the director would receive shares under the restricted share units that had vested through the date the director leaves the Board. RSUs entitle the holder to receive one ordinary share unit for each unit that vests. Holders of RSUs are not entitled to any of the rights of a holder of ordinary shares, including the right to vote, unless and until their units vest and ordinary shares are issued but they are entitled to receive dividend equivalents with respect to their units. Dividend equivalents will be denominated in cash and paid in cash if and when the underlying units vest. The following table summarizes information about RSUs issued to non-employee directors as at March 31, 2018 Restricted Share Units As at March 31, 2018 As at March 31, 2017 RSU Holder Amount Granted Amount Granted Non-Employee Directors 29,025 24,456 Chairman 12,900 10,962 Compensation costs charged against income in respect of RSUs granted to non-employee directors for the three months ended March 31, 2018 were $0.3 million ( 2017 — $0.4 million . The total tax charge recognized by the Company in relation to non-employee RSUs in the three months ended March 31, 2018 was $ Nil ( 2017 — $ Nil ). |

In addition, the Company recognized $14.1 million of contingent consideration, with a total maximum payable of $22.8 million , subject to the future performance of the business and $2.0 million of ceding commission. The total consideration for the acquisition was $69.1 million . A significant proportion of the acquired business was represented by intangible assets, specifically $25.0 million for agency relationships, $4.0 million for the right to use the AgriLogic trademark, $2.9 million for non-compete agreements, $1.8 million for the value of business acquired and $1.0 million for consultancy relationships. In addition, $12.0 million of software was acquired and was recognized in the balance sheet under office properties and equipment along with $0.3 million of residual net assets.

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingent Liabilities | Commitments and Contingent Liabilities (a) Restricted assets The Company is obliged by the terms of its contractual obligations to specific policyholders and by obligations to certain regulatory authorities to facilitate issue of letters of credit or maintain certain balances in deposits and trust funds for the benefit of policyholders. The following table details the forms and value of the Company’s restricted assets as at March 31, 2018 and December 31, 2017 : As at March 31, 2018 As at December 31, 2017 ($ in millions, except percentages) Regulatory trusts and deposits: Affiliated transactions $ 1,366.1 $ 1,455.0 Third party 2,416.1 2,425.3 Letters of credit / guarantees (1) 792.7 658.5 Investment commitment — real estate fund 100.0 100.0 Total restricted assets $ 4,574.9 $ 4,638.8 Total as percent of investable assets (2) 55.6 % 53.4 % (1) As at March 31, 2018 , the Company had pledged funds in the amount of $792.7 million ( December 31, 2017 — $658.5 million ) as collateral for the secured letters of credit. (2) Investable assets comprise total investments, cash and cash equivalents, accrued interest, receivables for securities sold and payables for securities purchased. Investment Commitment - Real Estate Fund. On December 20, 2017, the Company committed $100.0 million as a limited partner to a real estate fund. As of March 31, 2018 , the Company had not received a capital call. On May 10, 2018, the Company received an initial capital call of $86.2 million . The investment objective of the fund is to achieve attractive risk-adjusted returns through the acquisition of income producing, high quality assets in gateway cities located in the U.S. and Canada in the office, retail, industrial and multifamily sectors of the real estate market. Investments in this fund may be redeemed on a quarterly basis with 90 days’ notice subject to available cash in the fund once the lock-up period ends two years after the capital call. If sufficient cash is not available then all requested redemptions will be made on a pro rata basis. If a redemption request has not been met in full, as of such calendar quarter, the remaining portion of the request will be redeemed in subsequent quarters. There are no assurances as to when the Company may be able to withdraw, in whole or in part, its redemption request from the fund. Funds at Lloyd’s. AUL operates at Lloyd’s as the corporate member for Syndicate 4711. Lloyd’s determines Syndicate 4711’s required regulatory capital principally through the syndicate’s annual business plan. Such capital, called Funds at Lloyd’s, consists of investable assets as at March 31, 2018 in the amount of $452.8 million ( December 31, 2017 — $458.7 million ). The amounts provided as Funds at Lloyd’s are drawn upon and become a liability of the Company in the event Syndicate 4711 declares a loss at a level that cannot be funded from other resources, or if Syndicate 4711 requires funds to cover a short term liquidity gap. The amount which the Company provides as Funds at Lloyd’s is not available for distribution to the Company for the payment of dividends. Aspen Managing Agency Limited, the managing agent to Syndicate 4711, is also required by Lloyd’s to maintain a minimum level of capital which as at March 31, 2018 was £0.4 million ( December 31, 2017 — £0.4 million ). This is not available for distribution by the Company for the payment of dividends. Credit Agreement. On March 27, 2017, Aspen Holdings and certain of its direct or indirect subsidiaries (collectively, the “Borrowers”) entered into a Second Amended and Restated Credit Agreement (the “Credit Agreement”) with various lenders and Barclays Bank plc, as administrative agent. The Credit Agreement will be used by the Borrowers to finance the working capital needs of the Company and its subsidiaries, for letters of credit in connection with the insurance and reinsurance businesses of the Company and its subsidiaries and for other general corporate purposes. Initial availability under the Credit Agreement is $200,000,000 and the Company has the option (subject to obtaining commitments from acceptable lenders) to increase the Credit Agreement by up to $100,000,000 . The Credit Agreement will expire on March 27, 2022. As at March 31, 2018 , no borrowings were outstanding under the Credit Agreement. The fees and interest rates on the loans and the fees on the letters of credit payable by the Borrowers under the Credit Agreement are based upon the credit ratings for the Company’s long-term unsecured senior debt by S&P and Moody’s. In addition, the fees for a letter of credit vary based upon whether the applicable Borrower has provided collateral (in the form of cash or qualifying debt securities) to secure its reimbursement obligations with respect to such letter of credit. Under the Credit Agreement, the Company must not permit (a) consolidated tangible net worth to be less than approximately $2,323,100,000 plus 25% of consolidated net income plus 25% of aggregate net cash proceeds from the issuance by the Company of its capital stock, in each case after January 1, 2017, (b) the ratio of its total consolidated debt to the sum of such debt plus its consolidated tangible net worth to exceed 35% or (c) any material insurance subsidiary to have a financial strength rating of less than B++ from A.M. Best. The Credit Agreement contains other customary affirmative and negative covenants, including (subject to various exceptions) restrictions on the ability of the Company and its subsidiaries to incur indebtedness, create or permit liens on their assets, engage in mergers or consolidations, dispose of assets, pay dividends or other distributions, purchase or redeem the Company’s equity securities, make investments and enter into transactions with affiliates. In addition, the Credit Agreement has customary events of default, including (subject to certain materiality thresholds and grace periods) payment default, failure to comply with covenants, material inaccuracy of representation or warranty, bankruptcy or insolvency proceedings, change of control and cross-default to other debt agreements. Other Credit Facilities. On June 30, 2016, Aspen Bermuda and Citibank Europe plc (“Citi Europe”) amended the committed letter of credit facility, dated June 30, 2012, as amended on June 30, 2014 (the “LOC Facility”). The amendment to the LOC facility extends the term of the LOC Facility to June 30, 2018 and provides a maximum aggregate amount of up to $550.0 million . Under the LOC Facility, Aspen Bermuda will pay to Citi Europe (a) a letter of credit fee based on the available amounts of each letter of credit and (b) a commitment fee, which varies based upon usage, on the unutilized portion of the LOC Facility. Aspen Bermuda will also pay interest on the amount drawn by any beneficiary under the LOC Facility at a rate per annum of LIBOR plus 1% (plus reserve asset costs, if any) from the date of drawing until the date of reimbursement by Aspen Bermuda. In addition, Aspen Bermuda and Citi Europe entered into an uncommitted letter of credit facility whereby Aspen Bermuda has the ability to request letters of credit under this facility subject to the prior approval of Citi Europe. The fee associated with the uncommitted facility is a letter of credit fee based on the available amounts of each letter of credit issued under the uncommitted facility. Both the LOC Facility and the uncommitted facility are used to secure obligations of Aspen Bermuda to its policyholders. In addition to these facilities, we also use regulatory trusts to secure our obligations to policyholders. The terms of a pledge agreement between Aspen Bermuda and Citi Europe (pursuant to an assignment agreement dated October 11, 2006) dated January 17, 2006, as amended, were also amended on June 30, 2014 to change the types of securities or other assets that are acceptable as collateral under the New LOC Facility. All other agreements relating to Aspen Bermuda’s LOC Facility, which now apply to the LOC Facility with Citi Europe, as previously filed with the SEC, remain in full force and effect. As at March 31, 2018 , we had $444.2 million of outstanding collateralized letters of credit under the LOC Facility ( December 31, 2017 — $449.4 million under the LOC Facility). (b) Operating leases Amounts outstanding under operating leases net of subleases as at March 31, 2018 were: 2018 2019 2020 2021 2022 Later Total ($ in millions) Operating Lease Obligations $ 15.9 $ 15.9 $ 15.4 $ 10.9 $ 8.9 $ 73.6 $ 140.6 (c) Contingent liabilities In common with the rest of the insurance and reinsurance industry, the Company is subject to litigation and arbitration in the ordinary course of business. The Company’s Operating Subsidiaries are regularly engaged in the investigation, conduct and defense of disputes, or potential disputes, resulting from questions of insurance or reinsurance coverage or claims activities. Pursuant to insurance and reinsurance arrangements, many of these disputes are resolved by arbitration or other forms of alternative dispute resolution. Such legal proceedings are considered in connection with estimating the Company’s Insurance Reserves — Loss and Loss Adjustment Expenses, as provided on the Company’s consolidated balance sheet. In some jurisdictions, noticeably the U.S., a failure to deal with such disputes or potential disputes in an appropriate manner could result in an award of “bad faith” punitive damages against the Company’s Operating Subsidiaries. In accordance with ASC 450-20-50-4b, for (a) reasonably possible losses for which no accrual is made because any of the conditions for accrual in ASC 450-20-25-2 are not met and (b) reasonably possible losses in excess of the amounts accrued pursuant to ASC 450-20-30-1, the Company will provide an estimate of the possible loss or range of possible loss or state that such an estimate cannot be made. As at March 31, 2018 and December 31, 2017 , based on available information, it was the opinion of the Company’s management that the probability of the ultimate resolution of pending or threatened litigation or arbitrations having a material effect on the Company’s financial condition, results of operations or liquidity would be remote. |

New Accounting Pronouncements Adopted in 2018 and Not Yet Adopted | Accounting Pronouncements Adopted in 2018 On August 12, 2015, the FASB issued ASU 2015-14, “ Revenue from Contracts with Customers (Topic 606)” which delayed the effective date of ASU 2014-09 by one year. ASU 2015-04 is effective for annual periods beginning after December 15, 2017. Adoption of this ASU during the three months ended March 31, 2018 did not have a material impact on the Company’s consolidated financial statements as insurance contracts accounted for within the scope of Topic 944, Financial Services are exempt from this ASU and the Company has immaterial other revenue. On January 5, 2016, the FASB issued ASU 2016-1, “ Financial Instruments - Overall (Subtopic 825-10)” which enhances the reporting model for financial instruments. Included within the requirements of this ASU are the following: a) equity investments to be measured at fair value with changes in fair value recognized in net income; b) a simplification of the impairment assessment of equity investments without readily determinable fair values; c) public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; and d) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The amendments required as a result of this ASU are effective for fiscal years beginning after December 15, 2017. Adoption of this ASU during the three months ended March 31, 2018 did not have a material impact on the Company’s consolidated financial statements as the Company’s equity portfolio, prior to being sold, was classified as held for trading with changes in fair value recognized through net income and no valuation allowance was required in relation to deferred tax asset related to available-for-sale securities Other accounting pronouncements were issued during the three months ended March 31, 2018 which were either not relevant to the Company or did not impact the Company’s consolidated financial statements. Accounting Pronouncements Not Yet Adopted On February 14, 2018, the FASB issued ASU 2018-02, “ Income Statement - Reporting Comprehensive Income (Topic 220)” which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. This ASU is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The Company is currently evaluating the provisions of ASU 2018-02 to determine how it will be affected, but no material impact is expected on the consolidated financial statements. On February 28, 2018, the FASB issued ASU 2018-03, “ Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10)” which amends multiple areas in Subtopic 825-10 via improvements to clarify the Codification or to correct unintended application of guidance. This ASU is effective for fiscal years beginning after December 15, 2017 and for interim periods within those fiscal years beginning after June 15, 2018. The Company is currently evaluating the provisions of ASU 2018-03 to determine how it will be affected, but no material impact is expected on the consolidated financial statements. Other accounting pronouncements were issued during the three months ended March 31, 2018 which were either not relevant to the Company or did not impact the Company’s consolidated financial statements. |
