ASPEN INSURANCE HOLDINGS LIMITED

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.	History and Organization

Aspen Insurance Holdings Limited (“Aspen Holdings”) was incorporated on May 23, 2002 and holds subsidiaries that provide insurance and reinsurance on a worldwide basis. Its principal operating subsidiaries are Aspen Insurance UK Limited (“Aspen U.K.”), Aspen Bermuda Limited (“Aspen Bermuda”), Aspen Specialty Insurance Company (“Aspen Specialty”), Aspen American Insurance Company (“AAIC”) and Aspen Underwriting Limited (corporate member of Lloyd’s Syndicate 4711, “AUL”) (collectively, the “Operating Subsidiaries”). We have also established Aspen Capital Management, Ltd and other related entities (“ACM”) which are used to leverage our existing franchise and underwriting expertise to offer investors access to diversified products. In such regard, Silverton Re Ltd. (“Silverton”), a sidecar, was established in 2013 to attract third-party capital and to provide additional collateralized capacity to support Aspen Re’s global reinsurance business. References to the “Company,” “we,” “us” or “our” refer to Aspen Holdings or Aspen Holdings and its subsidiaries.


2.	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 (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Results for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ended December 31, 2014 . 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, 2013 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, 2013 contained in the Company’s Annual Report on Form 10-K filed with the United States Securities and Exchange Commission on February 20, 2014 (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 relate to losses and loss adjustment expenses, the value of investments, reinsurance recoverables and the fair value of derivatives. All material assumptions and estimates are regularly reviewed and adjustments made as necessary, but actual results could be significantly different from those expected when the assumptions or estimates were made.

New Accounting Policies Adopted in 2014

In February 2013, the Financial Accounting Standards Board (“FASB”) issued ASU 2013-04, “ Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date ” to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date. Examples of obligations include debt arrangements, other contractual obligations and settled litigation and judicial rulings. ASU 2013-04 has been applied retrospectively and is effective for annual reporting periods beginning after December 15, 2013, and interim periods within those years. The Company adopted this ASU in the first quarter of 2014 and this standard does not have a material impact on its consolidated financial statements.

In March 2013, the FASB issued ASU 2013-05, “ Parent’s Accounting for the Cumulative Translation Adjustment Upon Derecognition of Certain Subsidiaries or Groups of Assets Within a Foreign Entity or of an Investment in a Foreign Entity ” to standardize the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in its foreign entities or no longer holds a controlling financial interest in a subsidiary. ASU 2013-05 has been applied prospectively and is effective for annual reporting periods beginning after December 15, 2013, and interim periods within those years. The Company adopted this ASU in the first quarter of 2014 and this standard does not have a material impact on its consolidated financial statements unless it should choose to sell its investments in its foreign entities or cease to hold a controlling financial interest.

In July 2013, the FASB issued ASU 2013-11, “ Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ” which provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward

Table of Contents

exists. ASU 2013-11 is effective for fiscal years beginning after December 15, 2013 or interim periods within those years. The Company adopted this ASU in the first quarter of 2014 and it does not have a material impact on its consolidated financial statements as its presentation of unrecognized tax benefits is already as required by ASU 2013-11.

In March 2014, the FASB issued ASU 2014-06, “ Technical Corrections and Improvements Related to Glossary Terms ” which includes technical corrections related to glossary links, glossary term deletions, and glossary term name changes. In addition, ASU 2014-06 includes more substantive, limited-scope improvements to reduce instances of the same term appearing multiple times in the Master Glossary with similar, but not entirely identical, definitions. The amendments apply to all reporting entities within the scope of the affected accounting guidance, do not have transition guidance and are effective upon issuance for both public entities and nonpublic entities. The Company adopted this ASU in the first quarter of 2014 and it does not have a material impact on its consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

On June 27, 2013, the FASB issued a proposed Accounting Standards Update, Insurance Contracts (Topic 834). The FASB invited individuals and organizations to comment on the proposed Update and the comment period has now closed. The main objectives of the guidance in this proposed update is to increase the usefulness of the information about an entity’s insurance liabilities, including the nature, amount, timing, and uncertainty of cash flows related to those liabilities, and the related effect on the statement of comprehensive income, and to provide comparability, regardless of the type of entity issuing the contract. The guidance in this proposed update would require an entity to measure its insurance contracts under one of two measurement models, referred to as the building block approach and the premium allocation approach.

Under the proposed FASB guidance, there would be changes to the earnings pattern of underwriting and net investment margins and changes in the pattern and amount of revenue. In addition, there would likely be increased income statement volatility due to the requirement to update assumptions each period. Income statement volatility would be somewhat mitigated by the requirement that the impact of changes in discount rate assumptions be recorded in other comprehensive income. Adoption will have significant impacts on business strategy, investor education, key performance indicators, underlying processes, systems, internal controls, valuation models, and other fundamental aspects of the business. An entity would apply the guidance in this proposed update retrospectively, restating all comparative periods presented. Early adoption of the guidance in this proposed update would be prohibited.

4.	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. 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 share for the three months ended March 31, 2014 and 2013 , respectively:

5.	Segment Reporting

The Company has two reporting business segments: Insurance and Reinsurance. In arriving at these reporting segments, the Company has considered similarities in economic characteristics, products, customers, distribution, the regulatory environment of the Company’s operating segments and quantitative thresholds to determine the Company’s reportable segments. Segment profit or loss for each of the Company’s operating 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 segment’s underwriting performance.

Reinsurance Segment. The reinsurance segment consists of property catastrophe reinsurance, other property reinsurance (risk excess, pro rata, facultative and engineering), casualty reinsurance (U.S. treaty, international treaty and global facultative) and specialty reinsurance (credit and surety, agriculture and other specialty). Our recently established ACM forms part of our property catastrophe reinsurance line of business, as it currently focuses entirely on property catastrophe business through the use of alternative capital. For a more detailed description of this segment, see Part I, Item 1, “Business — Business Segments — Reinsurance” in the Company’s 2013 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

Table of Contents

Insurance Segment. The insurance segment consists of property and casualty insurance, marine, aviation and energy insurance and financial and professional lines insurance. As previously stated, we announced on November 8, 2013 that our property and casualty insurance lines of business would be integrated into a combined property and casualty line. This includes the programs business, previously reported separately. For a more detailed description of this segment, see Part I, Item 1 “Business — Business Segments — Insurance” in the Company’s 2013 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

Non-underwriting Disclosures. The Company has provided additional disclosures for corporate and other (non-underwriting) 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, which are not allocated to the underwriting segments. Corporate expenses are not allocated to the Company’s operating segments as they typically do not fluctuate with the levels of premiums written and are not directly related to the Company’s segment operations. The Company does not allocate its assets by segment as it evaluates underwriting results of each 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, 2014 and 2013 :

The Company classifies these financial instruments as held for trading as this most closely reflects the facts and circumstances of the investments held. Unrealized foreign exchange gains and losses included in the tables above are included within net realized and unrealized foreign exchange gains/(losses) within the statement of operations and other comprehensive income.

As of March 31, 2014 , the Company had invested $25.1 million in U.S. Dollar BB high yield bonds classified within corporate securities and $72.7 million in its U.S. Dollar bank loans trading portfolio. In August 2013, the Company invested in a $200.0 million BBB rated Emerging Market Debt portfolio (“EMD”), which is reported above in corporate and foreign government securities. In early March 2014, we increased our investment in equities by $40.0 million in a new minimum volatility equity portfolio.

Catastrophe Bonds. The Company has invested in catastrophe bonds with a total value of $18.0 million as of March 31, 2014 . The bonds receive quarterly interest payments based on variable interest rates with scheduled maturities ranging from 2015 to 2020. The redemption value of the bonds will adjust based on the occurrence of a covered event, such as windstorms and earthquakes which occur in the geographic region of the United States, Canada, the North Atlantic, Japan and Australia.

Other Investments. The Company previously had an equity accounted investment in Cartesian Iris Offshore Fund L.P (“Cartesian”), which provided capital to Iris Re, a Class 3 Bermuda reinsurer. On June 29, 2013, the Company notified Cartesian Capital Group of its intention to withdraw the Company’s investment in Cartesian and to terminate the services provided to Iris Re. This took effect on January 1, 2014. For more information regarding the Company’s investment in Cartesian, refer to Note 6 of the “Notes to Audited Consolidated Financial Statements” in the Company’s 2013 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

On October 2, 2012, the Company established a subsidiary, Aspen Recoveries Limited, to take ownership of a 58.5% shareholding in Chaspark Maritime Holdings Ltd., a Singaporean registered company (“Chaspark”), with the remaining shareholding owned by other insurers. The shareholding in Chaspark was received as a settlement for subrogation rights associated with a contract frustration claim settlement. The Company has determined that Chaspark has the characteristics of a variable interest entity (“VIE”) as addressed by the guidance in ASC 810, Consolidation . However, having considered the provisions of ASC 810, Consolidation , the Company’s investment in Chaspark does not permit the Company to direct the activities which most significantly impact Chaspark’s economic performance and the Company is not acting as principal or agent for a related party group of investors. Under these circumstances, the Company is not required to consolidate Chaspark. The investment is therefore accounted for under the equity method. Adjustments to the carrying value of this investment are made based on the Company’s share of capital including share of income and expenses, which is provided in the quarterly management accounts. In the three months ended March 31, 2014 , there was no change in the value of the Company’s investment in Chaspark ( March 31, 2013 — $ Nil ). The adjusted carrying value approximates fair value.

Guaranteed Investments. As at March 31, 2014 , the Company held $2.3 million ( December 31, 2013 — $2.3 million ) in investments which are guaranteed by mono-line insurers, excluding those with explicit government guarantees, and the Company’s holding was limited to two municipal securities, both rated BB or higher ( December 31, 2013 — two municipal securities, both rated BBB- or higher). The standalone rating (rating without guarantee) is determined as the senior unsecured debt rating of the issuer. Where the credit ratings were split between the two main rating agencies, Standard & Poor’s Financial Services LLC (“S&P”) and Moody’s Investors Service, Inc. (“Moody’s”), the lowest rating was used. The Company’s exposure to other third-party guaranteed debt is primarily to investments backed by non-U.S. government guaranteed issuers.

7.	Variable Interest Entities

As at March 31, 2014 , the Company had two investments in VIEs, Chaspark and Silverton.

Chaspark. On October 2, 2012, the Company established a subsidiary, Aspen Recoveries Limited, to take ownership of a 58.5% shareholding in Chaspark, with the remaining shareholding owned by other insurers. The shareholding in Chaspark was received as a settlement for subrogation rights associated with a contract frustration claim settlement. The Company has determined that Chaspark has the characteristics of a VIE as addressed by the guidance in ASC 810, Consolidation . As discussed further in Note 6 of these unaudited condensed consolidated financial statements, the investment in Chaspark is accounted for under the equity method. In the three months ended March 31, 2014 , there was no change in the value of the Company’s investment in Chaspark ( March 31, 2013 — $ Nil ). The adjusted carrying value approximates fair value.

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 reinsurance business. In respect of the debt issued by Silverton to investors, Silverton has entered into a retrocession agreement with Aspen Bermuda effective January 1, 2014. Under this agreement, Silverton receives a quota share of Aspen Bermuda’s catastrophe business. Silverton is a non-rated insurer and the risks have been fully collateralized by way of funds held in trust for the benefit of Aspen Bermuda. Silverton is able to provide investors with access to diversified natural catastrophe risk backed by the distribution, underwriting, analysis and research expertise of Aspen Re.

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 and has consolidated the subsidiary upon its formation as it owns 100% of the voting shares, 100% of the issued share capital and has a significant financial interest and the power to control Silverton. The Company has no other obligation to provide financial support to Silverton. Neither the creditors nor beneficial interest holders of Silverton have recourse to the Company’s general credit.

In the event of either an extreme catastrophic property reinsurance event or severe credit related event there is a risk that Aspen Bermuda 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 by way of a trust in favor of Aspen Bermuda as the beneficiary;


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.

Silverton issued $65.0 million of loan notes on December 27, 2013 (of which $50.0 million was issued to third parties and $15.0 million to Aspen Holdings), which provides quota share support for Aspen Re’s global property catastrophe excess of loss reinsurance business. The operations of Silverton commenced on January 1, 2014. The Company’s maximum loss exposure to Silverton is its $15.0 million loan note holdings as at March 31, 2014 ( December 31, 2013 — $15.0 million ) due to

mature on September 16, 2016 plus the change in fair value of the notes. The fair value of the loan notes held by the Company has increased $1.0 million for the three months ended March 31, 2014. The total aggregate unpaid balance of the loan notes is $69.4 million .

The table below shows the Company’s liabilities associated with the third-party investments in Silverton for the three months ended March 31, 2014 :

Cartesian. The Company previously had an equity accounted investment in Cartesian, which provided capital to Iris Re, a Class 3 Bermuda reinsurer. On June 29, 2013, the Company notified Cartesian Capital Group of its intention to withdraw the Company’s investment in Cartesian and to terminate the services provided to Iris Re. This took effect on January 1, 2014. For more information regarding the Company’s investments in Cartesian and Chaspark, refer to Note 6 of the “Notes to Audited Consolidated Financial Statements” in the Company’s 2013 Annual Report filed on Form 10-K filed with the United States Securities and Exchange Commission.


8.	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.

Table of Contents

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, 2014 and December 31, 2013 , respectively:

Valuation of Fixed Maturities . The Company’s fixed income maturity securities are classified as either available for sale or trading and carried at fair value. As at March 31, 2014 and December 31, 2013 , the Company’s fixed income securities were valued by pricing services, index providers or broker-dealers using standard market conventions. The market conventions

Table of Contents

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. Quotes from broker-dealers are non-binding.

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, 2014 , the Company obtained an average of 2.6 quotes per fixed income investment, compared to 2.6 quotes as at December 31, 2013 . Pricing sources used in pricing fixed income investments as at March 31, 2014 and December 31, 2013 were as follows:

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 provider 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 market or information available from 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.

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, Foreign 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.

Table of Contents

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 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 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 includes a portion of the 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 the FDIC program or other similar non-U.S. 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 includes the Company’s BB High Yield Bonds and a portion of the BBB Emerging Market Debt 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.

Bank Loans. These are variable rate, senior secured debt instruments issued by non-investment grade companies that are not publicly registered but are the most senior debt in a capital structure and are generally secured by company assets. Although these assets do not trade in as liquid a market as traditional fixed income instruments, they are valued in similar fashion to other fixed maturities, using similar inputs such as yield curves, interest rates and credit spreads. These securities are primarily priced by a third party pricing vendor. Bank loans are therefore classified 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 maturity investments and are classified within Levels 1 and 2.

Equity Securities. Equity securities include U.S. and foreign common stocks and are classified either as trading or available for sale and carried at fair value. These securities are classified within Level 1 as their fair values are based on quoted market prices in active markets from independent pricing sources. As at March 31, 2014 , the Company obtained an average of 3.9 quotes per equity investment, compared to 4.9 quotes as at December 31, 2013 . Pricing sources used in pricing equities as at March 31, 2014 and December 31, 2013 were all provided by index providers.

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.

Table of Contents

Interest Rate Swaps. The interest rate swaps which the Company uses to mitigate interest rate risk are also characterized as OTC and are valued by the counterparty using quantitative models with multiple market inputs. The market inputs, such as interest rates and yield curves, are observable and the valuation can be compared for reasonableness with third party pricing services. Consequently, these instruments are classified as Level 2.

Loan Notes Issued by Variable Interest Entities . Silverton, a licensed special purpose insurer, is consolidated into the Company’s group accounts as a VIE. Additionally, in the fourth quarter of 2013, Silverton issued $65.0 million ( $50.0 million third-party funded) loan notes with a maturity date of September 16, 2016. The Company has 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 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. The seasonality used in the model is 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 valuation model are based on Company specific data due to the lack of availability of observable market inputs. Reserves for losses is 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, 2014 are presented in the table below:



At March 31, 2014		Fair Value Level 3		Valuation Method	Observable (O) and Unobservable (U) inputs	Low		High
	($ in millions)					($ in millions)
Loan notes held by third parties		$	53.4	Internal Valuation Model	Gross premiums written (O)	$	—	$	39.5
					Reserve for losses (U)	$	—	$	2.4
					Contract period (O)	N/A		365 days
					Initial value of issuance (O)	$	50.0	$	50.0


9.	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 largest concentrations of reinsurance recoverables as at March 31, 2014 were 25.9% with Lloyd’s syndicates ( December 31, 2013 — 23.5% ) and 18.3% with Munich Re ( December 31, 2013 — 17.1% ).


10.	Derivative Contracts

The following table summarizes information on the location and amounts of derivative fair values on the consolidated balance sheet as at March 31, 2014 and December 31, 2013 :

Foreign Exchange Contracts. 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, 2014 , the Company held foreign exchange contracts with an aggregate notional value of $253.2 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, 2014 , the impact of foreign exchange contracts on net income was a gain of $3.0 million ( March 31, 2013 — charge of $4.8 million ).

Interest Rate Swaps. As at March 31, 2014 , the Company held fixed for floating interest rate swaps with a total notional amount of $1.0 billion ( December 31, 2013 — $1.0 billion ) that are due to mature between August 4, 2014 and November 9, 2020. The interest rate swaps are used in the ordinary course of the Company’s investment activities to partially mitigate the negative impact of rises in interest rates on the market value of the Company’s fixed income portfolio. For the three months ended March 31, 2014 , there was a charge in respect of the interest rate swaps of $1.9 million ( March 31, 2013 — gain of $0.6 million ).

As at March 31, 2014 , cash collateral with a fair value of $29.1 million was held by the Company’s counterparties to support the current valuation of the interest rate swaps ( December 31, 2013 — $34.3 million ). As at March 31, 2014 , no non-cash collateral was transferred to the Company by its counterparties ( December 31, 2013 — $ Nil ). Transfers of cash collateral are recorded on the consolidated balance sheet within Derivatives at Fair Value, while transfers in respect of non-cash collateral are disclosed but not recorded. As at March 31, 2014 , no amount was recorded in the consolidated balance sheet for the pledged assets.

None of the derivatives mentioned above meet the requirements for hedge accounting as per ASC 815 Derivatives and Hedging and therefore changes in the estimated fair value are included in the consolidated statement of operations.

Table of Contents

Additional paid-in capital as at March 31, 2014 was $1,269.9 million ( December 31, 2013 — $1,297.4 million ). Additional paid-in capital includes the aggregate liquidation preferences of the Company’s preference shares of $568.2 million ( December 31, 2013 — $568.2 million ) less issue costs of $12.4 million ( December 31, 2013 — $12.4 million ).

Ordinary Shares. The following table summarizes transactions in the Company’s ordinary shares during the three months ended March 31, 2014 :



	Number of Ordinary Shares
Ordinary shares in issue at December 31, 2013	65,546,976
Ordinary share transactions in the three months ended March 31, 2014
Ordinary shares issued to employees under the 2003 and 2013 share incentive plans and/or 2008 share purchase plan	641,191
Ordinary shares issued to non-employee directors	1,309
Ordinary shares repurchased	(770,505	)
Ordinary shares in issue at March 31, 2014	65,418,971

Ordinary Share Repurchases . On February 7, 2013 , the Company’s Board of Directors replaced the then existing share repurchase authorization of $400.0 million with a new authorization of $500.0 million . The total share repurchase authorization, which was effective immediately through February 7, 2015, permits the Company to effect the repurchases from time to time through a combination of transactions, including open market repurchases, privately negotiated transactions and accelerated share repurchase transactions.

Under open market repurchases, the Company acquired and cancelled in the three months ended March 31, 2014 770,505 ordinary shares. The total consideration paid was $30.9 million , with the average price being $40.08 . Under open market repurchases, the Company acquired and cancelled 1,681,333 ordinary shares for the three months ended March 31, 2013 . The total consideration paid was $58.2 million and the average price was $34.63 .

Preference Shares Redemption. During 2005 and 2006, the Company issued 4.6 million 5.625% Perpetual Preferred Income Equity Replacement Securities (“PIERS”). The PIERS were convertible at the Company’s option if, at any time on or after January 1, 2009, the closing sale price of the Company’s ordinary shares equaled or exceeded 130% of the then prevailing conversion price for 20 trading days during any consecutive 30 -trading day period, as well as the last day of such 30 -day period.

The PIERS were dilutive to the Company’s ordinary shares when the Company’s share price exceeded the prevailing conversion price and therefore, as the Company’s share price was generally above the 130% conversion price test, they were included in the Company’s fully diluted share count until the Company announced it would mandatorily redeem the PIERS.

On April 25, 2013, the Company announced it would mandatorily redeem all of its PIERS outstanding based on the terms of the PIERS. Each holder of a PIERS unit received $50.00 , equating to a total payment of $230.0 million in cash plus a number of the Company’s ordinary shares based on the conversion rate calculated in accordance with the average trading price of the Company’s ordinary shares over a 20 -trading day settlement period following the Company’s issuance of the press release announcing the mandatory conversion. The conversion rate was 1.7121 shares of the Company’s ordinary shares per $50.00 liquidation preference of the PIERS equating to a total issuance of 1,835,860 ordinary shares. The Company settled the amount on May 30, 2013. In accordance with the terms of the PIERS, no further dividends were paid on the PIERS following the announcement of their mandatory redemption. The $7.1 million reclassification from additional paid-in capital to retained earnings is the difference between the capital raised upon issuance of the PIERS, net of original issuance costs, and the final redemption of the PIERS in the amount of $230.0 million .

Preference Shares Issuance. On May 2, 2013, the Company issued 11.0 million shares of 5.95% of Fixed-to-Floating Perpetual Non-Cumulative Preference Shares (the “ 5.95% Preference Shares”). Each preference shareholder will receive dividends on a non-cumulative basis only when declared by the Board of Directors initially at an annual fixed rate of 5.95% until July 1, 2023 at which time a floating rate, reset quarterly, of 3-month LIBOR plus 4.06% will commence per annum. The 5.95% Preference Shares have a liquidation preference of $25.00 per share and net proceeds were $270.4 million (comprising $275.0 million of total liquidation preference less $4.6 million of issue expenses).

The Company used $230.0 million of the net proceeds from this offering for settling the cash portion of the mandatory conversion of the PIERS.

The 5.95% Preference Shares rank equally with preference shares previously issued by the Company and have no fixed maturity date. The Company may redeem all or a portion of the 5.95% Preference Shares at a redemption price of $25.00 per

Table of Contents

share on or after July 1, 2023. The Company has listed the 5.95% Preference Shares on the New York Stock Exchange under the symbol “AHLPRC.”

Rights Agreement. On April 17, 2014, the Board of Directors of the Company resolved to issue one preferred share purchase right (a “Right”) for each outstanding ordinary share, and adopted a shareholder rights plan, as set forth in the Rights Agreement dated as of April 17, 2014. Each Right will allow its holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preference Shares for $160 , once the Rights become exercisable. The Rights will not be exercisable until 10 business days after the public announcement that a person or group has acquired the beneficial ownership of 10% or more of the outstanding ordinary shares of the Company (or 15% in the case of passive institutional investors).


14.	Share-Based Payments

The Company issued options and other equity incentives under two arrangements: the employee incentive plans and the non-employee director plan. When options are exercised or other equity awards have vested, new shares are issued as the Company does not currently hold treasury shares.

Employee and Non-Employee Director Awards. Employee options and other awards were granted under the Aspen 2003 Share Incentive Plan, as amended (the “2003 Share Incentive Plan”), prior to April 24, 2013 and thereafter under the new 2013 Share Incentive Plan. The total number of ordinary shares that may be issued under the 2013 Share Incentive Plan is 2,845,683 shares, which includes 595,683 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. The non-employee director awards are granted under the 2006 Stock Option Plan for Non-Employee Directors.

Stock options were granted with an exercise price equivalent to the fair value of the share on the grant date. The weighted average value at grant date is determined using the Black-Scholes option pricing model. Stock options typically vest over a three -year period with a ten -year contract period (except for options granted in 2007 which have a seven -year exercise period) with vesting dependent on time and performance conditions established at the time of grant. No options were granted during the three months ended March 31, 2014 ( 2013 — Nil ) and 19,579 options were exercised and issued in the three months ended March 31, 2014 ( 2013 — 241,742 options). No charges against income were made in respect of employee options for the three months ended March 31, 2014 ( 2013 — $ Nil ).

Restricted share units (“RSUs”) granted to employees vest over a three -year period typically, based on continued service. Some of the grants vest at year-end, while some other grants vest on the anniversary of the date of grant or when the Compensation Committee of the Board of Directors agrees to deliver them. The fair value of the RSUs is based on the closing price on the date of the grant and is expensed through the income statement evenly over the vesting period. During the three months ended March 31, 2014 , the Company did no t grant any RSUs to its employees ( 2013 — 258,179 RSUs). In the case of non-employee directors, generally one-twelfth of the RSUs vest on each one month anniversary of the date of grant, with 100% of the RSUs becoming vested on the first anniversary of the date of grant. On February 6, 2014 (with a grant date of February 10, 2014), the Board of Directors approved a total of 27,180 RSUs for the non-employee directors (February 4, 2013 — 25,533 ) and 13,590 RSUs to the Chairman (February 4, 2013 — 14,188 ). Compensation costs charged against income in respect of RSUs for the three months ended March 31, 2014 were $3.0 million ( 2013 — $0.6 million ).

Performance Shares. During the three months ended March 31, 2014, the Company did no t grant any performance shares to any of its employees (February 11, 2013 — 250,066 ).

The fair value of performance share awards is based on the value of the closing share price on the date of the grant less a deduction for expected dividends which would not accrue during the vesting period. Compensation costs charged against income in the three months ended March 31, 2014 in respect of performance shares were $1.5 million ( 2013 — $3.4 million ).

Phantom Shares. During the three months ended March 31, 2014, the Company did no t grant any phantom shares to any of its employees (February 6, 2013 — 152,541 ).

The fair value of the phantom shares is based on the closing share price on the date of the grant, less estimated dividends payable over the vesting period. The fair value is expensed through the consolidated income statement evenly over the vesting period, but as the payment to beneficiaries will ultimately be in cash rather than 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, 2014 in respect of phantom shares were $1.2 million ( 2013 — $2.1 million ).

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 Employee Share Purchase Plan, employees can save up to $500 per month over a two -year period, at the end of which they will be eligible to purchase Company shares at a discounted price, subject to a further one year holding period. In respect of the

Table of Contents

2008 Sharesave Scheme, employees can save up to £250 per month over a three -year period (and effective April 6, 2014, £500 per month), at the end of which they will be eligible to purchase Company shares at a discounted price. The purchase price will be eighty-five percent 85% of the fair market value of a share on the offering date which may be adjusted upon changes in capitalization of the Company. Under the ESPP, 9,994 ordinary shares were issued during the three months ended March 31, 2014 ( 2013 — 13,415 shares). Compensation costs charged against income in the three months ended March 31, 2014 in respect of the ESPP were $ 0.1 million ( 2013 — $ 0.1 million ).

The licenses are tested for impairment annually or when events or changes in circumstances indicate that the asset might be impaired.

Other. In 2010, the Company purchased APJ Continuation Limited and its subsidiaries (“APJ”) for an aggregate consideration of $4.8 million . The directors of Aspen Holdings assessed the fair value of the net tangible and financial assets acquired at $1.2 million .

⁽¹⁾	As of March 31, 2014 , the Company had pledged funds of $813.3 million and £16.1 million ( December 31, 2013 — $803.7 million and £16.1 million ) as collateral for the secured letters of credit.

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, comprises cash, investments and a fully collateralized letter of credit. The fully collateralized letter of credit has been provided by Aspen Bermuda and is disclosed in the above table as an affiliated transaction.

The amounts provided as Funds at Lloyd’s will be drawn upon and become a liability of the Company in the event of Syndicate 4711 declaring 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, 2014 was $0.7 million ( December 31, 2013 — $0.7 million ). This is not available for distribution by the Company for the payment of dividends.

Interest Rate Swaps. As at March 31, 2014 , cash collateral with a fair value of $29.1 million was held by the Company’s counterparties to support the current valuation of the interest rate swaps ( December 31, 2013 — $34.3 million ). For more information, please refer to Note 10 of these unaudited condensed consolidated financial statements.


(b)	Operating leases

Amounts outstanding under operating leases net of subleases as of March 31, 2014 were:

	($ in millions)
Operating Lease Obligations	$	6.6	$	12.6	$	8.6	$	7.5	$	6.2	$	7.1	$	48.6


(c)	Contingent liabilities

In common with the rest of the insurance and reinsurance industry, the Company is also 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 of March 31, 2014 , 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.


17.	Subsequent Events

On April 14, 2014, an unsolicited proposal was announced by Endurance Specialty Holdings Ltd. (“Endurance”) to acquire the Company for a combination of Endurance common stock and cash. The Board of Directors has, following consultation with our financial and legal advisors, rejected the proposal.

Some of the information contained in this discussion and analysis or set forth elsewhere in this report, including information with respect to our plans and strategy for our business and in “Outlook and Trends” below, includes forward-looking statements that involve risks and uncertainties. Please see the section captioned “Cautionary Statement Regarding Forward-Looking Statements” in this report and the “Risk Factors” in Item 1A of our 2013 Annual Report on Form 10-K for more information on factors that could cause actual results to differ materially from the results described in, or implied by, any forward-looking statements contained in this discussion and analysis.

Overview

We are a Bermuda holding company and write insurance and reinsurance business through our wholly-owned subsidiaries in Bermuda, the U.K. and the U.S. In the quarter, we continued to make progress in our establishment of ACM, which is used to leverage our existing franchise and underwriting expertise to offer third-party investors access to diversified products.

Some of the key results for the three months ended March 31, 2014 were:


•	Gross written premiums of $855.5 million for the first quarter of 2014 , an increase of 10.6% from the first quarter of 2013 . Gross written premiums in reinsurance increased by 7.4% while insurance grew 14.8% as a result of the continued strategic growth of the U.S. and international insurance teams;


•	Net favorable development on prior year loss reserves of $28.2 million for the first quarter of 2014 compared with $26.2 million in the first quarter of 2013 ;

•

Combined ratio of 87.6% for the first quarter of 2014 compared with a combined ratio of 90.1% for the first quarter of 2013 . There were $10.6 million , or 1.9 combined ratio points, of catastrophe losses pre-tax net of reinsurance recoveries and reinstatement premiums in the first quarter of 2014 compared with minimal catastrophe losses in the first quarter of 2013 . Catastrophe losses included $6.6 million for U.S. weather-related events and $4.0 million for Japanese snowstorms and U.K. floods;


•	Diluted net income per share of $1.66 for the quarter ended March 31, 2014 compared with diluted net income per share of $1.15 in the same quarter last year;


•	Annualized net income return on average equity of 16.0% for the first quarter of 2014 compared with 11.6% for the first quarter of 2013 ; and


•	Diluted book value per share ⁽¹⁾ of $42.72 as at March 31, 2014, up 4.4% from December 31, 2013.

Total shareholders’ equity increased by $87.2 million to $3,386.8 million for the three months ended March 31, 2014 . The most significant movements were:


•	a $99.1 million increase in retained earnings for the period;


•	the repurchase of 770,505 ordinary shares for $30.9 million through open market repurchases; and


•	net unrealized gains on investments, net of taxes, of $20.3 million .

Recent Developments

As previously disclosed, on April 17, 2014, the Board of Directors resolved to issue one preferred share purchase right (a “Right”) on each share of our ordinary shares issued and outstanding as of the close of business on April 28, 2014 and adopted a shareholder rights plan, as set forth in the rights agreement entered into on the same date between the Company and Computershare Inc. (the “Rights Agreement”). The Rights Agreement will expire on April 16, 2015, and the Board of Directors may terminate the Rights Agreement at any time if it no longer believes that the Rights Agreement is in the best interests of the Company and its shareholders.

On April 23, 2014, the Board of Directors approved an 11.1% increase in dividends on our ordinary shares, from $0.18 per ordinary share to $0.20 per ordinary share. The ordinary share dividend is payable on May 28, 2014 to holders of record as of the close of trading on May 9, 2014.

Outlook and Trends

Overall. For the first quarter of 2014, average rates decreased by approximately 3% on renewals across both reinsurance and insurance with approximately 5% in reinsurance while average rates have remained flat in insurance.

We continue to make good progress on our strategic objectives, our operating results and our profitability, and we are confident that we are laying the foundation for continuing improvement beyond 2014. We are executing on enhancing investment returns, managing capital and business portfolio optimization to seek to continue to increase operating return on equity through 2014. We have made a significant investment in our U.S. Insurance platform and have an established, growing U.S. Insurance franchise. In the reinsurance segment, we advanced our U.S. and non-U.S. regional reinsurance strategy, which allows us to provide a better service to a wider range of clients across the U.S., Continental Europe, Asia Pacific and Latin America. With respect to ACM, the industry has been changing and with the flow of alternative capital into the reinsurance market we responded strategically to capitalize on new opportunities.

Reinsurance. In reinsurance, the property catastrophe market, which has been the most accessed by alternative capital, is experiencing the most rate pressure. For the property catastrophe market we expect rates to continue to fall by 15-20% for 2014 depending on region and specific account loss experience. For other property, which is non-catastrophe exposed property risk, the rate environment is slightly less pressured and we expect rates to decline in the range of 5-10%. For specialty business, while it varies by the type of risk, in aggregate we expect rates to be flat to down slightly. For casualty reinsurance we expect rates to decline in the range of 2-5% depending upon the line of business, experience and jurisdiction.

Insurance. In insurance, overall, rates are broadly flat. In property and casualty, casualty is continuing to show rate improvement while there is some softening on property especially in low loss activity accounts. In financial and professional lines, rate activity is dependent on each specific line but overall rates are flat to slightly lower. In marine, aviation and energy, marine rates are relatively flat, energy liability are seeing some increases following loss activity, aviation and onshore and offshore energy continue to experience pricing pressure.

Application of Critical Accounting Policies

Our condensed consolidated financial statements are based on the selection of accounting policies and require management to make significant estimates and assumptions. Some of the more critical judgments in the areas of accounting estimates and assumptions that affect our financial condition and results of operations are related to insurance reserves, premiums receivable in respect of assumed reinsurance, the fair value of derivatives and the value of investments, including the extent of any other-than-temporary impairment. For a detailed discussion of our critical accounting policies, please refer to Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies” in our 2013 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission and the notes to the consolidated condensed unaudited financial statements contained in this report.

We have discussed the application of these critical accounting policies with our Board of Directors and Audit Committee.

Results of Operations for the Three Months Ended March 31, 2014 Compared to the Three Months Ended March 31, 2013

The following is a discussion and analysis of our consolidated results of operations for the three months ended March 31, 2014 and 2013 , starting with a summary of our consolidated results and followed by a segmental analysis.

Total Income Statement

Our statements of operations consolidate the underwriting results of our two business segments and include certain other revenue and expense items that are not allocated to segments.

Gross written premiums. Gross written premiums increased by $82.1 million , or 10.6% , in the first quarter of 2014 compared to the first quarter of 2013 . Premiums from our reinsurance segment increased by 7.4% reflecting growth in catastrophe and other property lines offset by planned reductions and adverse prior year premium adjustments in casualty lines. Our insurance segment’s premiums increased by 14.8% principally due to growth in U.S. lines and global casualty lines. The table below shows our gross written premiums for each segment for the three months ended March 31, 2014 and 2013 , and the percentage change in gross written premiums for each segment:



Business Segment	Three Months Ended March 31, 2014		Three Months Ended March 31, 2013		% increase
	($ in millions)		($ in millions)
Reinsurance	$	472.2	$	439.6	7.4	%
Insurance	383.3		333.8		14.8	%
Total	$	855.5	$	773.4	10.6	%

Ceded reinsurance. Total reinsurance ceded for the quarter of $158.0 million decreased by $18.4 million from the first quarter of 2013 due to reductions in reinsurance purchased within our insurance segment following our decision to retain more risk.

Net premiums earned. Net premiums earned in the first quarter of 2014 increased by 10.9% from the first quarter of 2013 , broadly consistent with the increase in gross written premiums in the period.

Losses and loss adjustment expenses. The loss ratio for the quarter of 50.9% reduced by 1.7 percentage points compared to the first quarter of 2013 due to lower current year losses and higher reserve releases. In the reinsurance segment, the reduction in the loss ratio was due to the impact of a $6.6 million satellite loss in 2013 while the current quarter recognized $5.5 million of catastrophe losses associated with U.S. and Japanese storms and a $1.1 million increase in prior year reserve releases from $20.1 million in the first quarter of 2013 to $21.2 million in the current period.

In the insurance segment, the loss ratio for the quarter of 59.3% decreased by 1.4 percentage points compared to the first quarter of 2013 due to two large losses totaling $9.4 million in U.K. property and casualty while the current quarter recognized $5.1 million of catastrophe losses from U.S. and U.K. storms and a $0.9 million increase in prior year reserve releases from $6.1 million in the first quarter of 2013 to $7.0 million in the current period.

We monitor the ratio of losses and LAE to net earned premium (the “loss ratio”) as a measure of relative underwriting performance where a lower ratio represents a better result than a higher ratio. The loss ratios for our two business segments for the three months ended March 31, 2014 and 2013 were as follows:



Business Segment	Three Months Ended March 31, 2014		Three Months Ended March 31, 2013
Reinsurance	41.4	%	44.5	%
Insurance	59.3	%	60.7	%
Total Loss Ratio	50.9	%	52.6	%

We also present, in the table below, loss ratios both including and excluding the impact from catastrophe losses to aid in the analysis of the underlying performance of our segments. For this purpose, we have defined the major first quarter 2014 catastrophe losses as losses associated with winter storms in the U.S. and Japan and flood losses in the U.K. There were no major catastrophes in the first quarter of 2013.

Table of Contents

The underlying changes in loss ratios by segment are shown in the tables below for the three months ended March 31, 2014 and 2013 . The total loss ratio represents the calendar year U.S. GAAP loss ratio. The current year adjustments represent catastrophe loss events which reflect net claims and related reinstatement premium adjustments.



For the Three Months Ended March 31, 2014	Total Loss Ratio		Current Year Adjustments		Loss Ratio Excluding Current Year Adjustments
Reinsurance	41.4	%	(2.1	)%	39.3	%
Insurance	59.3	%	(1.7	)%	57.6	%
Total	50.9	%	(1.9	)%	49.0	%



For the Three Months Ended March 31, 2013	Total Loss Ratio		Current Year Adjustments		Loss Ratio Excluding Current Year Adjustments
Reinsurance	44.5	%	—	%	44.5	%
Insurance	60.7	%	—	%	60.7	%
Total	52.6	%	—	%	52.6	%

Reserve releases in our reinsurance segment increased from $20.1 million in the first quarter of 2013 to $21.2 million in the current period. Favorable reserve development in our specialty, casualty and catastrophe reinsurance lines were the main contributors to the release. The insurance segment had a $7.0 million reserve release this quarter, due primarily to favorable development in property and casualty business lines. The release of $6.1 million in the comparative quarter of 2013 was due primarily to favorable development in property, casualty and financial and professional lines, but partially offset by strengthening in marine, energy and construction liability and our programs business.

Expense ratio. We monitor the ratio of expenses to net earned premium (the “expense ratio”) as a measure of the cost effectiveness of our amortization of deferred policy acquisition costs, general, administrative and corporate processes. The table below splits the net expense ratio between the amortized deferred policy acquisition costs, general, administrative and corporate expenses and the effect of reinsurance for each of the three months ended March 31, 2014 and 2013 :



	Three Months Ended March 31, 2014						Three Months Ended March 31, 2013
Ratios Based on Gross Earned Premium	Reinsurance		Insurance		Total		Reinsurance		Insurance		Total
Policy acquisition expense ratio	18.1	%	16.5	%	17.2	%	20.3	%	15.8	%	17.9	%
General and administrative expense ratio ⁽¹⁾	11.8		12.3		14.7		11.8		13.6		14.8
Gross expense ratio	29.9		28.8		31.9		32.1		29.4		32.7
Effect of reinsurance	1.3		7.0		4.8		1.9		6.7		4.8
Total net expense ratio	31.2	%	35.8	%	36.7	%	34.0	%	36.1	%	37.5	%


⁽¹⁾	The total group general and administrative expense ratio includes corporate expenses.

Policy acquisition expenses have increased by $7.4 million due primarily to growth in premiums written while the acquisition expense ratio has fallen by 0.7 percentage points due to lower reinsurance costs increasing net earned premiums and changes in the business mix.

General, administrative and corporate expenses increased by $ 9.0 million , including $3.0 million in non-recurring corporate expenses for the quarter compared to the first quarter of 2013 which is attributable to the growth in our premiums and increases in headcount, performance-related accruals and corporate costs. However, consistent with our growth in earned premium, the general, administrative and corporate expense ratio decreased overall by 0.1 percentage points.

Net investment income. Net investment income for the quarter of $49.5 million increased by 2.5% compared to $48.3 million in the first quarter of 2013 due primarily to increases in dividend income arising from our equity portfolio, which increased by $93.7 million as at March 31, 2014 compared to March 31, 2013.

Change in fair value of derivatives. In the three months ended March 31, 2014 , we recorded a loss of $1.9 million ( 2013 — gain of $0.6 million ) in respect of interest rate swaps due to declining interest rates and a gain of $3.0 million ( 2013 — loss of $4.8 million ) in respect of foreign exchange contracts.

Taxes. Income tax expense for the three months ended March 31, 2014 was $3.8 million ( 2013 — $5.9 million ) equating to an estimated effective tax rate of 3.1% ( 2013 — 6.0% ). The effective tax rate represents an estimate of the tax rate which will apply to our pre-tax income for 2014 including adjustments to prior period estimates. The effective tax rate for the year is subject to revision in future periods if circumstances change and depends on the relative profitability of those parts of business underwritten in Bermuda (where the rate of tax on corporate profits is zero ), the U.K. (where the corporate tax rate was 23% , and decreased to 21% from April 1, 2014) and the U.S. (where the corporate tax rate is 34% ).

Net income after tax. Net income after tax for the three months ended March 31, 2014 was $120.4 million , equivalent to basic earnings per share of $1.70 adjusted for the $9.5 million preference share dividends. Fully diluted earnings per ordinary share were $1.66 . Net income after tax for the three months ended March 31, 2013 was $91.8 million , equivalent to basic earnings per ordinary share of $1.21 adjusted for the $8.6 million preference share dividend and fully diluted earnings per ordinary share of $1.15 .

Investment gains . Realized and unrealized investment gains for the three months ended March 31, 2014 were $13.6 million ( 2013 — $15.2 million ) comprising the amounts set out in the table below:

Other comprehensive income. Total other comprehensive income was $15.5 million ( 2013 — loss of $21.6 million ), net of taxes, for the three months ended March 31, 2014 . This is comprised of a $20.5 million gain in the net unrealized available for sale investment portfolio ( 2013 — $9.7 million net unrealized loss) largely attributable to the impact of rising interest rates on our bond portfolios, $0.2 million reclassification of net realized gains to net income ( 2013 — $6.5 million reclassified net

realized losses), net unrealized losses in foreign currency translation of $4.8 million ( 2013 — $5.5 million net unrealized losses) and an amortization of loss on derivative contracts of $ Nil ( 2013 — $0.1 million ).

Dividends. As announced on April 23, 2014, the dividend on our ordinary shares increased from $0.18 per ordinary share to $0.20 per ordinary share. Dividends paid on our ordinary and preference shares in the three months ended March 31, 2014 were $21.2 million ( 2013 — $20.5 million ).

Underwriting Results by Operating Segments — First Quarter

We are organized into two business segments: Reinsurance and Insurance. The reinsurance segment consists of property catastrophe reinsurance, other property reinsurance, casualty reinsurance and specialty reinsurance. The insurance segment consists of property and casualty insurance, marine, aviation and energy insurance and financial and professional lines insurance. As previously stated, we announced on November 8, 2013 that our property and casualty insurance lines of business would be integrated into a combined property and casualty line. This includes the programs business, previously reported separately.

We have provided additional disclosures for corporate and other (non-underwriting) income and expenses in Note 5 of our unaudited condensed consolidated financial statements included in this report. Corporate and other income includes net investment income, net realized and unrealized investment gains or losses, corporate expenses, interest expense, net realized and unrealized foreign exchange gains or losses and income taxes, none of which are allocated to the business segments.

Please refer to the tables in Note 5 in our unaudited condensed consolidated financial statements of this report for a summary of gross and net written and earned premiums, underwriting results and combined ratios and reserves for our two business segments for the three months ended March 31, 2014 and 2013 . The contributions of each segment to gross written premiums in the three months ended March 31, 2014 and 2013 were as follows:



	Gross Written Premiums
Business Segment	Three Months Ended March 31, 2014		Three Months Ended March 31, 2013

Reinsurance	$	472.2	$	439.6
Insurance	383.3		333.8
Total	$	855.5	$	773.4

Reinsurance

Our reinsurance segment consists of property catastrophe reinsurance, other property reinsurance (risk excess, pro rata, facultative and engineering), casualty reinsurance (U.S. treaty, international treaty and global facultative) and specialty reinsurance (credit and surety, agriculture and other specialty). For a more detailed description of this segment, see Part I, Item 1, “Business — Business Segments — Reinsurance” in the Company’s 2013 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

Table of Contents

Gross written premiums. Gross written premiums in our reinsurance segment increased by 7.4% compared to the three months ended March 31, 2013 . The table below shows our gross written premiums for each line of business for the three months ended March 31, 2014 and 2013 , and the percentage change in gross written premiums for each such line:



Lines of Business	Three Months Ended March 31, 2014		Three Months Ended March 31, 2013		% increase/ (decrease)
	($ in millions)		($ in millions)
Property catastrophe reinsurance	$	168.8	$	145.5	16.0	%
Other property reinsurance	102.4		79.5		28.8	%
Casualty reinsurance	113.3		125.3		(9.6	)%
Specialty reinsurance	87.7		89.3		(1.8	)%
Total	$	472.2	$	439.6	7.4	%

The increase in property catastrophe premiums in the first quarter of 2014 is mainly attributable to the impact of our new capital markets team which has enabled us to increase line sizes. The increase in other property reinsurance is predominantly due to growth in our pro rata business which had a strong renewal season during the first quarter of 2014 across most regions. Gross written premiums in casualty reinsurance decreased primarily due to reductions in prior year premium estimates and planned reductions in some casualty lines.

Losses and loss adjustment expenses. The loss ratio for the three months ended March 31, 2014 was 41.4% compared to 44.5% in the equivalent period in 2013 . The reduction in the loss ratio is primarily attributable to lower current year losses and increased reserve releases. In the first quarter of 2014, we experienced only $5.5 million of natural catastrophe losses in the quarter: $2.5 million of losses associated with U.S. storms and $3.0 million of losses associated with Japanese snow storms. The comparable quarter of 2013 was adversely affected by $6.6 million of satellite losses. There was a $1.1 million increase in prior year reserve releases from $20.1 million in the first quarter of 2013 to $21.2 million in the current period. Reserve releases for the quarter were mainly as a result of favorable development in the property catastrophe and specialty lines. Further information relating to the movement of prior year reserves is found below under “Reserves for Losses and Loss Adjustment Expenses.”

Policy acquisition, general and administrative expenses. Amortization of deferred policy acquisition costs were $ 50.4 million for the three months ended March 31, 2014 equivalent to 18.9% of net premiums earned ( 2013 — $ 55.3 million or 21.5% of net premiums earned). The expenses in the prior year were adversely affected by increased profit commission accruals in our specialty and casualty lines. The general and administrative expense ratio of 12.3% decreased from 12.5% for the same period in 2013 due predominantly to an increase in net earned premiums in the quarter.

Insurance

Our 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 segment, see Part I, Item 1 “Business — Business Segments — Insurance” in the Company’s 2013 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

Gross written premiums. Gross written premiums in our insurance segment increased by 14.8% for the quarter from $333.8 million in the equivalent period in 2013 . The table below shows our gross written premiums for each line of business for the three months ended March 31, 2014 and 2013 , and the percentage change in gross written premiums for each line:



Lines of Business	Three Months Ended March 31, 2014		Three Months Ended March 31, 2013		% increase/ (decrease)
	($ in millions)		($ in millions)
Property and casualty insurance	$	176.3	$	131.2	34.4	%

Financial and professional lines insurance	75.3		65.8		14.4	%
Total	$	383.3	$	333.8	14.8	%

The increase in gross written premium is mainly attributable to our U.K. and U.S. property and casualty lines and U.S. financial and professional lines.

Table of Contents

Losses and loss adjustment expenses. The loss ratio for the quarter was 59.3% compared to 60.7% for the three months ended March 31, 2013 , with the reduction due to lower current year losses and higher reserve releases. The loss ratio for the quarter has been adversely affected by $5.1 million of catastrophe losses associated with U.S. and U.K weather-related events. The comparative period in 2013 experienced no significant catastrophe losses, but was adversely affected by two large losses totaling $9.4 million in U.K. property and casualty. There has been a $0.9 million increase in prior year reserve releases from $6.1 million in the first quarter of 2013 to $7.0 million in the current quarter.

The reserve releases in the current quarter were mainly attributable to shorter-tail business lines, principally our U.S. and U.K. property, U.S. energy and inland marine lines. The release in the comparative quarter in 2013 was due to favorable loss development in our aviation, credit, political risk and terrorism risks lines as well as a small release in casualty lines.

Policy acquisition, general and administrative expenses. Amortization of deferred policy acquisition costs for the three months ended March 31, 2014 increased marginally to 20.5% of net premiums earned compared to 19.4% in the first quarter of 2013 as a result of changes in business mix and some commission adjustments in our financial and professional lines written in the U.K. Our general and administrative expenses increased by $3.5 million to $45.9 million from $42.4 million in the first quarter of 2013 due to growth in our U.S. business but the expense ratio has reduced by 1.4 percentage points commensurate with the increase in net earned premium.

Equity Securities . In March 2011, we initiated an investment into a high quality global equity income strategy via direct investment. In January 2013, we increased our investment in our trading equities portfolio by an additional $200.0 million. Equity securities are comprised of U.S. and foreign equity securities and are classified as available for sale or trading. The portfolio targets high quality global equity securities with attractive dividend yields. In early March 2014, we increased our investment in equities by $40 million in a new minimum volatility equity portfolio. Our overall portfolio strategy remains focused on high quality fixed income investments. The total investment return from the available for sale and trading equity portfolios for the three months ended March 31, 2014 and 2013 are as follows:

Interest rate swaps. We continue to maintain our $1.0 billion interest rate swaps program to partially mitigate the negative impact of rising interest rates on the market value of our fixed income portfolio. During the quarter our interest rate swap position was down $1.9 million which consisted of a $4.3 million mark to market gain less $6.2 million of net interest payments. As at March 31, 2014, our interest-rate swap position reduced the duration of the fixed-income portfolio from 3.46 years to 3.15 years and the duration of the aggregate portfolio from 2.83 years to 2.57 years.

European Fixed Income & Equity Exposures. As at March 31, 2014 , we had $1,100.8 million , or 13.0% of our total cash and investments, invested in European issuers, including the U.K. Our European exposures consisted of sovereigns, agencies, government guaranteed bonds, covered bonds, corporate bonds and equities. We have no exposure to the sovereign debt of Greece, Ireland, Italy, Portugal or Spain (“GIIPS”), and de minimis holdings of Spanish and Italian corporate bonds and equities.

We manage our European fixed income exposures by proactively adapting our investment guidelines to our views on the European debt crisis. In August 2010, we amended our investment guidelines to prohibit purchases of GIIPS sovereign or guaranteed debt. We also prohibited purchases of peripheral European bank issuers. In November 2010, we amended our investment guidelines to prohibit purchases of corporate bonds issued by companies domiciled in any of the GIIPS countries. In May 2011, we amended our investment guidelines to prohibit purchases of European and U.K. corporate financial issuers including covered bonds. We also added Belgium to our list of prohibited sovereign investments. We do not actively hedge any of our European exposures.

Reserves for Losses and Loss Adjustment Expenses

As of March 31, 2014 , we had total net loss and loss adjustment expense reserves of $4,408.6 million ( December 31, 2013 — $4,346.2 million ). This amount represented our best estimate of the ultimate liability for payment of losses and loss adjustment expenses. The following tables analyze gross and net loss and loss adjustment expense reserves by segment as at March 31, 2014 and December 31, 2013 , respectively:



	As at March 31, 2014
Business Segment	Gross		Reinsurance Recoverable			Net
	($ in millions)
Reinsurance	$	2,683.9	$	(57.6	)	$	2,626.3
Insurance	2,076.8		(294.5		)	1,782.3
Total losses and loss expense reserves	$	4,760.7	$	(352.1	)	$	4,408.6



	As at December 31, 2013
Business Segment	Gross		Reinsurance Recoverable			Net
	($ in millions)
Reinsurance	$	2,707.0	$	(60.2	)	$	2,646.8

Total losses and loss expense reserves	$	4,678.9	$	(332.7	)	$	4,346.2

For the three months ended March 31, 2014 , there was a reduction of our estimate of the ultimate net claims to be paid in respect of prior accident years of $28.2 million . An analysis of this reduction by business segment is as follows for each of the three months ended March 31, 2014 and 2013 :



	For the Three Months Ended
Business Segment	March 31, 2014		March 31, 2013
	($ in millions)
Reinsurance	$	21.2	$	20.1
Insurance	7.0		6.1
Total losses and loss expense reserves reductions	$	28.2	$	26.2

The key elements which gave rise to the net positive development during the three months ended March 31, 2014 were as follows:

Reinsurance. Net reserve releases of $21.2 million in the current quarter were attributable to our specialty, casualty and property catastrophe reinsurance lines. The largest releases in the quarter were $16.0 million from specialty reinsurance due to a combination of a reduction in 2011 prior claim estimates, mainly from short-tail lines and the final settlement of a large contract. In addition, there was a $4.6 million reduction from casualty reinsurance lines due to favorable development.

Insurance. Net reserve releases of $7.0 million in the current quarter were mainly attributable to shorter-tail business lines, principally our U.S. and U.K. property, U.S. energy and inland marine lines.

We did not make any significant changes in assumptions used in our reserving process. However, because the period of time we have been in operation is relatively short, for longer tail lines in particular, our loss experience is limited and reliable evidence of changes in trends of numbers of claims incurred, average settlement amounts, numbers of claims outstanding and average losses per claim will necessarily take years to develop.

Capital Management

The following table shows our capital structure as at March 31, 2014 compared to December 31, 2013 :



	As at March 31, 2014		As at December 31, 2013
	($ in millions)
Share capital, additional paid-in capital, retained income and accumulated other comprehensive income attributable to ordinary shareholders	$	2,831.2	$	2,744.0
Preference shares (liquidation preferences net of issue costs)	555.8		555.8
Long-term debt	549.0		549.0
Loan notes issued by variable interest entities	53.4		50.0
Total capital	$	3,989.4	$	3,898.8

As at March 31, 2014 , total shareholders’ equity was $3,386.8 million compared to $3,299.6 million at December 31, 2013 . Our total shareholders’ equity as at March 31, 2014 includes three classes of preference shares with a total value as measured by their respective liquidation preferences of $555.8 million net of share issuance costs ( December 31, 2013 — $555.8 million ).

On April 24, 2013, we announced a 5.9% increase in our normal quarterly dividend to our ordinary shareholders from $0.17 per share to $0.18 per ordinary share, and a further 11.1% increase to $0.20 per ordinary share was approved on April 23, 2014.

On February 7, 2013, the Company’s Board of Directors replaced the existing share repurchase authorization of $400.0 million with a new authorization of $500.0 million . The total share repurchase authorization, which was effective immediately through February 7, 2015, permits the Company to effect the repurchases from time to time through a combination of transactions, including open market repurchases, privately negotiated transactions and accelerated share repurchase transactions.

We acquired and cancelled 770,505 ordinary shares for the three months ended March 31, 2014 . The total consideration paid was $30.9 million and the average price was $40.08 . As at March 31, 2014 , we had $193.3 million remaining under our current share repurchase authorization.

The amount outstanding under our senior notes, as of March 31, 2014 , less amortization of expenses was $549.0 million ( December 31, 2013 — $549.0 million ). In addition to the senior debt issued by Aspen Holdings, we have also reported $53.4 million of debt issued by Silverton ( December 31, 2013 — $50.0 million ). Management monitors the ratio of debt to total capital, with total capital being defined as shareholders’ equity plus outstanding debt. As at March 31, 2014 , this ratio was 15.1% ( December 31, 2013 — 15.4% ). Our preference shares are classified in our balance sheet as equity but may receive a different treatment in some cases under the capital adequacy assessments made by certain rating agencies. Such securities are often referred to as “hybrids” as they have certain attributes of both debt and equity. We also monitor the ratio of the total of debt and hybrids to total capital which was 29.0% as of March 31, 2014 ( December 31, 2013 — 29.6% ).

Access to capital. Our business operations are in part dependent on our financial strength and the market’s perception thereof, as measured by total shareholders’ equity, which was $3,386.8 million as at March 31, 2014 ( December 31, 2013 — $3,299.6 million ). We believe our financial strength provides us with the flexibility and capacity to obtain funds through debt or equity financing. Our continuing ability to access the capital markets is dependent on, among other things, our operating results, market conditions and our perceived financial strength. We regularly monitor our capital and financial position, as well as investment and securities market conditions, both in general and with respect to Aspen Holdings’ securities. Our ordinary shares and all of our preference shares are listed on the New York Stock Exchange.

Liquidity

Liquidity is a measure of a company’s ability to generate cash flows sufficient to meet short-term and long-term cash requirements of its business operations. Management monitors the liquidity of Aspen Holdings and of each of its Operating Subsidiaries and arranges credit facilities to enhance short-term liquidity resources on a stand-by basis.

Holding Company. We monitor the ability of Aspen Holdings to service debt, to finance dividend payments to ordinary and preference shareholders and to provide financial support to the Operating Subsidiaries.

As at March 31, 2014 , Aspen Holdings held $111.4 million of cash and cash equivalents ( December 31, 2013 — $94.2 million ) with the increase due to the receipt of dividend income from subsidiary companies less a total of $30.9 million of ordinary share repurchases in the three months ended March 31, 2014 . Management considers the current cash and cash equivalents, taken together with dividends declared or expected to be declared by subsidiary companies and our credit facilities,

Table of Contents

to be sufficient to appropriately satisfy the liquidity requirements of Aspen Holdings. Aspen Holdings’ liquidity depends on dividends, capital distributions and interest payments from our Operating Subsidiaries. Aspen Holdings has recourse to the credit facility described under “Credit Facility” below.

The ability of our Operating Subsidiaries to pay us dividends or other distributions is subject to the laws and regulations applicable to each jurisdiction, as well as the Operating Subsidiaries’ need to maintain capital requirements adequate to maintain their insurance and reinsurance operations and their financial strength ratings issued by independent rating agencies. On October 21, 2013, and in line with usual market practice for regulated institutions, the Prudential Regulation Authority (the “PRA”), the regulatory agency which oversees the prudential regulation of insurance companies in the U.K. such as Aspen U.K., requested that it be afforded the opportunity to provide a prior “non-objection” to all future dividend payments made by Aspen U.K. For a further discussion of the various restrictions on our ability and our Operating Subsidiaries’ ability to pay dividends, see Part I, Item 1 “Business — Regulatory Matters” in our 2013 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission. For a more detailed discussion of our Operating Subsidiaries’ ability to pay dividends, see Note 15 of the “Notes to the Audited Consolidated Financial Statements” in our 2013 Annual Report on Form 10-K filed with the United States Securities and Exchange.

Operating Subsidiaries. As of March 31, 2014 , the Operating Subsidiaries held $1,462.0 million ( December 31, 2013 — $1,150.2 million ) in cash and short-term investments that are readily realizable securities. Management monitors the value, currency and duration of cash and investments held by its Operating Subsidiaries to ensure that they are able to meet their insurance and other liabilities as they become due and was satisfied that there was a comfortable margin of liquidity as at March 31, 2014 and for the foreseeable future.

On an ongoing basis, our Operating Subsidiaries’ sources of funds primarily consist of premiums written, investment income and proceeds from sales and redemptions of investments.

Cash is used primarily to pay reinsurance premiums, losses and loss adjustment expenses, brokerage commissions, general and administrative expenses, taxes, interest and dividends and to purchase new investments.

The potential for individual large claims and for accumulations of claims from single events means that substantial and unpredictable payments may need to be made within relatively short periods of time.

We manage these risks by making regular forecasts of the timing and amount of expected cash outflows and ensuring that we maintain sufficient balances in cash and short-term investments to meet these estimates. Notwithstanding this policy, if our cash flow forecast is incorrect, we could be forced to liquidate investments prior to maturity, potentially at a significant loss.

The liquidity of our Operating Subsidiaries is also affected by the terms of our contractual obligations to policyholders and by undertakings to certain regulatory authorities to facilitate the issue of letters of credit or maintain certain balances in trust funds for the benefit of policyholders. The following table shows the forms of collateral or other security provided in respect of these obligations and undertakings as at March 31, 2014 and December 31, 2013 :

For more information on these arrangements, see Note 19(a) of the “Notes to the Audited Consolidated Financial Statements” in our 2013 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

Consolidated Cash Flows for the Three Months Ended March 31, 2014 . Total net cash flow from operations was $211.9 million , an increase of $108.4 million from the comparative period last year. The increase is mainly attributable to reduced claim payments made in the first three months of 2014 in respect of 2013 compared to claim payments made in the first three months of 2013 in respect of 2012 . For the three months ended March 31, 2014 , our cash flow from operations provided us with sufficient liquidity to meet our operating requirements.

Credit Facility. On June 12, 2013, we and certain of our direct and indirect subsidiaries (collectively, the “Borrowers”) entered into an amended and restated credit agreement (the “credit agreement”) with various lenders and Barclays Bank PLC, as administrative agent, which amends and restates the credit agreement dated as of July 30, 2010 among us, certain of our subsidiaries, various lenders and Barclays Bank PLC, as administrative agent. The credit facility will be used to finance our

Table of Contents

working capital needs and those of our subsidiaries, for letters of credit in connection with our insurance and reinsurance businesses and for other general corporate purposes. Initial availability under the credit facility is $200.0 million and we have the option (subject to obtaining commitments from acceptable lenders) to increase the facility by up to $100.0 million . The facility will expire on June 12, 2017. As of March 31, 2014 , no borrowings were outstanding under the credit facility. The fees and interest rates on the loans and the fees on the letters of credit payable by the Borrowers increase based on the consolidated leverage ratio of the Company.

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 facility, we must not permit (a) consolidated tangible net worth to be less than approximately $2,428.6 million plus 50% of consolidated net income and 50% of aggregate net cash proceeds from the issuance by the Company of its capital stock, in each case after January 1, 2013, (b) the ratio of our total consolidated debt to the sum of such debt plus our 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. In addition, the credit facility contains other customary affirmative and negative covenants as well as certain customary events of default, including with respect to a change in control. The various affirmative and negative covenants, include, among others, covenants that, subject to various exceptions, restrict the ability of the Company and its subsidiaries to: incur indebtedness; create or permit liens on assets; engage in mergers or consolidations; dispose of assets; pay dividends or other distributions; purchase or redeem the Company’s equity securities or those of its subsidiaries and make other restricted payments; make certain investments; agree with others to limit the ability of the Company’s subsidiaries to pay dividends or other restricted payments or to make loans or transfer assets to the Company or another of its subsidiaries. In addition, the credit facility 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. Our credit facility also contains customary provisions in respect of successor companies resulting from mergers and acquisitions assuming obligations thereunder.

Letters of Credit Facility. We have a $650.0 million letter of credit facility between Aspen Bermuda and Citibank Europe PLC. As at March 31, 2014 , we had $498.9 million of outstanding collateralized letters of credit under this facility compared to $516.8 million at December 31, 2013 .

Aspen U.K. and Aspen Bermuda have a $100.0 million secured letter of credit facility agreement with Barclays Bank PLC. As at March 31, 2014 , we had $18.7 million of outstanding collateralized letters of credit under this facility ( December 31, 2013 — $18.9 million ).

Contractual Obligations and Commitments

The following table summarizes our contractual obligations under long-term debt, operating leases (net of subleases) and reserves relating to insurance and reinsurance contracts as of March 31, 2014 :

⁽¹⁾	The long-term debt obligations disclosed above do not include the $29.0 million annual interest payments on our outstanding senior notes or dividends payable to holders of our preference shares or the loan notes issued by Silverton in the amount of $50.0 million .

⁽²⁾

In estimating the time intervals into which payments of our reserves for losses and loss adjustment expenses fall, as set out above, we have utilized actuarially assessed payment patterns. By the nature of the insurance and reinsurance contracts under which these liabilities are assumed, there can be no certainty that actual payments will fall in the periods shown and there could be a material acceleration or deceleration of claims payments depending on factors outside our control. This uncertainty is heightened by the relatively short time in which we have operated (relevant in particular to longer-tail lines), thereby providing limited Company-specific claims loss payment patterns. The total amount of payments in respect of our reserves, as well as the timing of such payments, may differ materially from our current estimates for the reasons set out in our 2013 Annual Report on Form 10-K under Item 7, “Management’s Discussion and

Further information on operating leases is given in Item 2, “Properties” in our 2013 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

Effects of Inflation

Inflation may have a material effect on our consolidated results of operations by its effect on interest rates and on the cost of settling claims. The potential exists, after a catastrophe or other large property loss, for the development of inflationary pressures in a local economy as the demand for services such as construction typically surges. The cost of settling claims may also be increased by global commodity price inflation. We seek to take both these factors into account when setting reserves for any events where we think they may be material.

Our calculation of reserves for losses and loss expenses in respect of casualty business includes assumptions about future payments for settlement of claims and claims-handling expenses, such as medical treatments and litigation costs. We write casualty business in the United States, the United Kingdom and Australia and certain other territories, where claims inflation has in many years run at higher rates than general inflation. To the extent inflation causes these costs to increase above reserves established for these claims, we will be required to increase our loss reserves with a corresponding reduction in earnings. The actual effects of inflation on our results cannot be accurately known until claims are ultimately settled.

In addition to general price inflation we are exposed to a persisting long-term upwards trend in the cost of judicial awards for damages. We seek to take this into account in our pricing and reserving of casualty business.

We also seek to take into account the projected impact of inflation on the likely actions of central banks in the setting of short-term interest rates and consequent effects on the yields and prices of fixed income securities. As of March 31, 2014 , we consider that although inflation is currently low, in the medium-term there is a risk that inflation, interest rates and bond yields may rise, resulting in a decrease in the market value of certain of our fixed interest investments.

Cautionary Statement Regarding Forward-Looking Statements

This Form 10-Q contains, and the Company may from time to time make other verbal or written, forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that involve risks and uncertainties, including statements regarding our capital needs, business strategy, expectations and intentions. Statements that use the terms “believe,” “do not believe,” “anticipate,” “expect,” “plan,” “estimate,” “project,” “outlook,” “trends,” “seek,” “will,” “may,” “aim,” “likely,” “continue,” “intend,” “guidance” and similar expressions are intended to identify forward-looking statements. These statements reflect our current views with respect to future events and because our business is subject to numerous risks, uncertainties and other factors, our actual results could differ materially from those anticipated in the forward-looking statements. The risks, uncertainties and other factors set forth in the Company’s 2013 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission and other cautionary statements made in this report, as well as the factors set forth below, should be read and understood as being applicable to all related forward-looking statements wherever they appear in this report.

All forward-looking statements rely on a number of assumptions, estimates and data concerning future results and events and are subject to a number of uncertainties and other factors, many of which are outside Aspen’s control that could cause actual results to differ materially from such statements.

Forward-looking statements do not reflect the potential impact of any future collaboration, acquisition, merger, disposition, joint venture or investments that Aspen may enter into or make, and the risks, uncertainties and other factors relating to such statements might also relate to the counterparty in any such transaction if entered into or made by Aspen.

All forward-looking statements address matters that involve risks and uncertainties. Accordingly, there are or will be important factors that could cause actual results to differ materially from those indicated in these statements. We believe that these factors include, but are not limited to, those set forth under “Risk Factors” in Item 1A of our Annual Report on Form 10-K filed with the United States Securities and Exchange Commission and the following:


•	the possibility of greater frequency or severity of claims and loss activity, including as a result of natural or man-made (including economic and political risks) catastrophic or material loss events, than our underwriting, reserving, reinsurance purchasing or investment practices have anticipated;

Table of Contents


•	the reliability of, and changes in assumptions to, natural and man-made catastrophe pricing, accumulation and estimated loss models;


•	decreased demand for our insurance or reinsurance products and cyclical changes in the insurance and reinsurance industry;


•	increased competition from existing insurers and reinsurers and from alternative capital providers and insurance-linked funds on the basis of pricing, capacity, coverage terms, new capital binding authorities to brokers, or other factors and the related demand and supply dynamics as contracts come up for renewal;


•	changes in general economic conditions, including inflation, foreign currency exchange rates, interest rates and other factors that could affect our financial results;


•	the risk of a material decline in the value or liquidity of all or parts of our investment portfolio;


•	evolving issues with respect to interpretation of coverage after major loss events;


•	any intervening legislative or governmental action and changing judicial interpretation and judgments on insurers’ liability to various risks;


•	the effectiveness of our risk management loss limitation methods;

•

changes in the total industry losses, or our share of total industry losses, resulting from past events such as the various catastrophes that occurred in the first quarter of 2014 , the German hailstorms, floods and other catastrophes in 2013, Superstorm Sandy in 2012, the Costa Concordia incident in early 2012, the floods in Thailand, various losses from the U.S. storms and the earthquake and ensuing tsunami in Japan in 2011, the floods in Australia in late 2010 and early 2011, the Deepwater Horizon incident in the Gulf of Mexico in 2010, the Chilean and the New Zealand Earthquakes in 2010 and 2011, and, with respect to such events, our reliance on loss reports received from cedants and loss adjustors, our reliance on industry loss estimates and those generated by modeling techniques, changes in rulings on flood damage or other exclusions as a result of prevailing lawsuits and case law;


•	the impact of one or more large losses from events other than natural catastrophes or by an unexpected accumulation of attritional losses;


•	the impact of acts of terrorism, acts of war and related legislation;


•	any changes in our reinsurers’ credit quality and the amount and timing of reinsurance recoverables;


•	changes in the availability, cost or quality of reinsurance or retrocessional coverage;


•	the continuing and uncertain impact of the current depressed lower growth economic environment in many of the countries in which we operate;


•	the level of inflation in repair costs due to limited availability of labor and materials after catastrophes;


•	a decline in our Operating Subsidiaries’ ratings with S&P, A.M. Best or Moody’s;


•	the failure of our reinsurers, policyholders, brokers or other intermediaries to honor their payment obligations;


•	our ability to execute our business plan to enter new markets, introduce new products and develop new distribution channels, including their integration into our existing operations;


•	our reliance on the assessment and pricing of individual risks by third parties;


•	our dependence on a few brokers for a large portion of our revenues;


•	the persistence of heightened financial risks, including excess sovereign debt, the banking system and the Eurozone debt crisis;


•	our ability to successfully implement steps to further optimize the business portfolio, ensure capital efficiency and enhance investment returns;


•	changes in our ability to exercise capital management initiatives (including our share repurchase program) or to arrange banking facilities as a result of prevailing market conditions or changes in our financial position;


•	changes in government regulations or tax laws in jurisdictions where we conduct business;


•	Aspen Holdings or Aspen Bermuda becoming subject to income taxes in the United States or the United Kingdom;


•	loss of one or more of our senior underwriters or key personnel;


•	our reliance on information technology and third-party service providers for our operations and systems; and


•	increased counterparty risk due to the credit impairment of financial institutions.

Table of Contents

In addition, any estimates relating to loss events involve the exercise of considerable judgment and reflect a combination of ground-up evaluations, information available to date from brokers and cedants, market intelligence, initial tentative loss reports and other sources. Due to the complexity of factors contributing to losses and the preliminary nature of the information used to prepare estimates, there can be no assurance that our ultimate losses will remain within stated amounts.

The rate changes described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Outlook and Trends” reflect management’s assessment of changes in exposure-adjusted rates on renewals only. This does not include contracts with fundamental changes to terms and conditions. The calculation involves a degree of judgment in relation to comparability of contracts in the different business lines. Due to changes in assumptions underlying the pricing of contracts, the trends in premium rates reflected in our outlook and trends may not be comparable over time. The future profitability of each business line is dependent upon many factors besides the trends in premium rates.

The foregoing review of important factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included in this report. We undertake no obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise or disclose any difference between our actual results and those reflected in such statements.

If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may vary materially from what we projected. Any forward-looking statements you read in this report reflect our current views with respect to future events and are subject to these and other risks, uncertainties and assumptions relating to our operations, results of operations, growth strategy and liquidity. All subsequent written and oral forward-looking statements attributable to us or individuals acting on our behalf are expressly qualified in their entirety by the points made above. You should specifically consider the factors identified in this report which could cause actual results to differ before making an investment decision.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest rate risk. Our investment portfolio consists primarily of fixed income securities. Accordingly, our primary market risk exposure is to changes in interest rates. Fluctuations in interest rates have a direct impact on the market valuation of these securities. As interest rates rise, the market value of our fixed income portfolio falls, and the converse is also true. Our strategy for managing interest rate risk includes maintaining a high quality portfolio with a relatively short duration to reduce the effect of interest rate changes on book value. In addition, the Company partially mitigates its exposure to interest rates by entering into interest rate swaps with financial institution counterparties in the ordinary course of its investment activities.

As at March 31, 2014 , our fixed income portfolio had an approximate duration of 3.46 years excluding the impact of interest rate swaps. The table below depicts interest rate change scenarios and the effects on our interest rate sensitive invested assets:



Effect of Changes in Interest Rates on Portfolio Given a Parallel Shift in the Yield Curve
Movement in Rates in Basis Points	-100		-50		—		50		100
	($ in millions, except percentages)
Market value $ in millions	6,979.2		6,862.5		6,745.8		6,629.1		6,512.4
Gain/(loss) $ in millions	233.4		116.7		—		(116.7	)	(233.4	)
Percentage of portfolio	3.5	%	1.7	%	—	%	(1.7	)%	(3.5	)%

Equity risk. We have invested in equity securities which had a fair market value of $507.8 million as at March 31, 2014 , equivalent to 6.0% of the total of investments, cash and cash equivalents at that date ( December 31, 2013 — $460.4 million , 5.6% ). These equity investments are exposed to equity price risk, defined as the potential for loss in market value due to a decline in equity prices. We believe that the effects of diversification and the relatively small size of our investments in equities relative to total invested assets mitigate our exposure to equity price risk.

Foreign currency risk. Our reporting currency is the U.S. Dollar. The functional currencies of our operations are U.S. Dollars, British Pounds, Euros, Canadian Dollars, Swiss Francs, Australian Dollars and Singaporean Dollars. As of March 31, 2014 , 71.6% ( December 31, 2013 — 82.1% ) of our cash, cash equivalents and investments were held in U.S. Dollars, 11.4% ( December 31, 2013 — 7.6% ) were in British Pounds and 17.0% ( December 31, 2013 — 10.3% ) were in other currencies. For the three months ended March 31, 2014 , 23.1% ( December 31, 2013 — 16.4% ) of our gross premiums were written in currencies other than the U.S. Dollar and the British Pound and we expect that a similar proportion will be written in currencies other than the U.S. Dollar and the British Pound in the remainder of 2014 .

Other foreign currency amounts are re-measured to the appropriate functional currency and the resulting foreign exchange gains or losses are reflected in the statement of operations. Functional currency amounts of assets and liabilities are then translated into U.S. Dollars. The unrealized gain or loss from this translation, net of tax, is recorded as part of shareholders’ equity. The change in unrealized foreign currency translation gain or loss during the period, net of tax, is a component of comprehensive income. Both the re-measurement and translation are calculated using current exchange rates for the balance sheets and average exchange rates for the statement of operations. We may experience exchange losses to the extent our foreign currency exposure is not hedged, which in turn would adversely affect our results of operations and financial condition. Management estimates that a 10% change in the exchange rate between British Pounds and U.S. Dollars as at March 31, 2014 would have impacted our net reportable British Pound net assets by approximately $5 million for the three months ended March 31, 2014 ( March 31, 2013 — approximately $10 million ).

We manage our foreign currency risk by seeking to match our liabilities under insurance and reinsurance policies that are payable in foreign currencies with investments that are denominated in these currencies. This may involve the use of foreign exchange contracts from time to time. 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 our assets and liabilities denominated in foreign currencies, but rather allow us to establish a rate of exchange for a future point in time. All realized gains and losses on foreign exchange contracts are recognized in the statement of operations as changes in fair value of derivatives. For the three months ended March 31, 2014 , the impact of foreign currency contracts on net income was a gain of $3.0 million ( 2013 — loss of $4.8 million ).

Table of Contents

Credit risk. We have exposure to credit risk primarily as a holder of fixed income securities. Our risk management strategy and investment policy is to invest predominantly in debt instruments of high credit quality issuers and to limit the amount of credit exposure with respect to particular ratings categories, business sectors and any one issuer. As at March 31, 2014 , the average rating of fixed income securities in our investment portfolio was “ AA -” ( December 31, 2013 — “ AA- ”). We also have credit risk through exposure to our interest rate swap counterparties who are Goldman Sachs Group (senior unsecured rating of “ Baa1 ” by Moody’s and “ A- ” by S&P) and Crédit Agricole CIB (senior unsecured rating of “ A2 ” by Moody’s and long term issuer credit rating of “ A ” by S&P).

In addition, we are exposed to the credit risk of our insurance and reinsurance brokers to whom we make claims payments for our policyholders, as well as to the credit risk of our reinsurers and retrocessionaires who assume business from us. Other than fully collateralized reinsurance, the substantial majority of our reinsurers have a rating of “A” (Excellent), the third highest of fifteen rating levels, or better by A.M. Best and the minimum rating of any of our material reinsurers is “A-” (Excellent), the fourth highest of fifteen rating levels, by A.M. Best.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, has evaluated the design and operation of the Company’s disclosure controls and procedures as of the end of the period of this report. Our management does not expect that our disclosure controls or our internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. As a result of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons or by collusion of two or more people. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. As a result of the inherent limitations in a cost-effective control system, misstatement due to error or fraud may occur and not be detected. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the disclosure requirements are met. Based on the evaluation of the disclosure controls and procedures, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective in ensuring that information required to be disclosed in the reports filed or submitted to the Commission under the Exchange Act by the Company is recorded, processed, summarized and reported in a timely fashion, and is accumulated and communicated to management, including the Company’s Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

The Company’s management has performed an evaluation, with the participation of the Company’s Chief Executive Officer and the Company’s Chief Financial Officer, of changes in the Company’s internal control over financial reporting that occurred during the three months ended March 31, 2014 . Based upon that evaluation, the Company’s management is not aware of any change in its internal control over financial reporting that occurred during three months ended March 31, 2014 that has materially affected, or is reasonably likely to materially affect, the effectiveness of the Company’s internal control over financial reporting.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

In common with the rest of the insurance and reinsurance industry, we are also subject to litigation and arbitration in the ordinary course of our business. Our 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 our insurance and reinsurance arrangements, many of these disputes are resolved by arbitration or other forms of alternative dispute resolution. 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 our Operating Subsidiaries.

While any legal or arbitration proceedings contain an element of uncertainty, we do not believe that the eventual outcome of any specific litigation, arbitration or alternative dispute resolution proceedings to which we are currently a party will have a material adverse effect on the financial condition of our business as a whole.

Item 1A. Risk Factors

The risk factors set forth below supplement the risk factors disclosed in Part I, Item IA “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2013. In addition to the below risk factors and other information set forth in this report, you should carefully consider the various risks and uncertainties contained in Part I, Item IA “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2013.

Anti-takeover provisions in our bye-laws, our shareholder rights plan and laws and regulations of the jurisdictions where we conduct business could delay or deter a takeover attempt that shareholders might consider desirable and may make it more difficult to replace members of our Board of Directors.

Our bye-laws contain provisions that may entrench directors and make it more difficult for shareholders to replace directors even if the shareholders consider it beneficial to do so. In addition, these provisions could delay or prevent a change of control that a shareholder might consider favorable. For example, these provisions may prevent a shareholder from receiving the benefit from any premium over the market price of our ordinary shares offered by a bidder in a potential takeover. Even in the absence of an attempt to effect a change in management or a takeover attempt, these provisions may adversely affect the prevailing market price of our ordinary shares if they are viewed as discouraging changes in management and takeover attempts in the future.

For example, our bye-laws contain the following provisions that could have such an effect:

• election of directors is staggered, meaning that members of only one of three classes of directors are elected each year;

• directors serve for a term of three years (unless aged 70 years or older);


•	our directors may decline to approve or register any transfer of shares to the extent they determine, in their sole discretion, that any non-de minimis adverse tax, regulatory or legal consequences to Aspen Holdings, any of its subsidiaries, shareholders or affiliates would result from such transfer;

•

if our directors determine that share ownership by any person may result in material adverse tax consequences to Aspen Holdings, any of its subsidiaries, shareholders or affiliates, we have the option, but not the obligation, to purchase or assign to a third party the right to purchase the minimum number of shares held by such person solely to the extent that it is necessary to eliminate such material risk;


•	shareholders have limited ability to remove directors; and


•	if the ordinary shares of any U.S. Person constitute 9.5% or more of the votes conferred by the issued shares of Aspen Holdings, the voting rights with respect to the controlled shares of such U.S. Person shall be limited, in the aggregate, to a voting power of less than 9.5%.

Further, our Board of Directors has adopted a shareholder rights plan, which, in general terms, works by imposing a significant penalty upon any person or group that acquires 10% or more of our outstanding ordinary shares (15% in the case of passive institutional investors) without the approval of the Board of Directors. The Board of Directors considered that some oppose the shareholder rights plan because of the view that it can delay or discourage a takeover attempt or make an unsolicited takeover of the Company more difficult. However, the Board of Directors adopted the plan and considered it to be in the best interests of the Company and its shareholders because the plan is designed to deter abusive tactics in any proposed takeover, to

Table of Contents

ensure that shareholders receive fair and equal treatment in any proposed takeover of the Company and to ensure that any transaction would appropriately reward our shareholders and be beneficial to our Company.

In addition, as described under Part I, Item 1, “Business — Regulatory Matters” in our Annual Report on Form 10-K for the year ended December 31, 2013, prospective shareholders are required to notify our regulators on becoming “controllers” of any of our Operating Subsidiaries through ownership of Aspen Holdings shares above certain thresholds, typically 10% of outstanding shares. Some regulators, such as the PRA, require their approval prior to such shareholder becoming a “controller.” Other regulators may serve a notice of objection or are entitled to injunctive relief.

There can be no assurance that the applicable regulatory body would agree that a shareholder who owned greater than 10% of our ordinary shares did not, because of the limitation on the voting power of such shares, control the applicable Operating Subsidiary. Furthermore, as described under “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity” above, any change of control would be an event of default under our credit facilities.

Endurance’s unsolicited proposal, and any future unsolicited proposals, may be disruptive to our business and may negatively impact our results of operations.

On April 14, 2014, Endurance Specialty Holdings Ltd. announced an unsolicited conditional proposal for our outstanding ordinary shares. Unsolicited proposals can create a significant distraction for management and may require that significant time, resources and costs are expended. Moreover, the hostile and unsolicited nature of the current proposal may cause uncertainty which could negatively impact our results of operations and strategic initiatives. Certain of our officers, including our named executive officers, have change in control/severance provisions in their employment arrangements with us. These retention and change in control arrangements are designed to mitigate this risk but may, ultimately, not be adequate to allow us to retain critical employees during a time when a change in control is being proposed or is imminent.

The Deferral Election, in addition to the requirements set forth below, must designate: (i) the amount of Compensation to be deferred, (ii) the time of the distribution, and (iii) the form of the distribution.

submitted within thirty (30) days after the date on which an Employee is first eligible to participate, and such Deferral Election shall apply to Compensation to be earned during the remainder of the calendar year after such election is made.

3.5 Cancellation of Deferral Election due to Disability

Notwithstanding anything to the contrary, if a Participant incurs a disability as defined in this Section 3.5, said Participant may file an election to stop Deferrals as of the date the election is received by the Administrator, provided that such cancellation occurs by the later of the end of the calendar year or the 15th day of the third month following the date the Participant incurs a disability. Disability for purposes of this Section 3.5 only means that a Participant incurs a medically determinable physical or mental impairment resulting in the Participant’s inability to perform the duties of his or her position or any substantially similar position, where such impairment can be expected to result in death or can be expected to last for a continuous period of not less than six months, as determined by the Administrator in its sole discretion.

3.6 Matching Contribution

The Employer may also credit to the Account of each Participant who makes Deferrals a Matching Contribution in an amount equal to a percentage of the Deferrals contributed by the Participant, with such percentage determined annually by the Employer, in its sole discretion. Such Matching Contribution shall be credited to such sub-account as may be elected by the Participant for his or her Salary Deferrals, or if no Salary Deferrals, then for Bonus Deferrals in accordance with Section 5.1 and procedures established by the Plan Administrator.

3.7 Employer Discretionary Contribution

The Employer may make discretionary contributions to some or all Participants’ Accounts in such amount and in such manner as may be determined by the Employer. Such Employer Discretionary Contribution, at the option of the Employer, shall be credited to such sub-account as may be elected by the Participant in accordance with Sections 3.1 and 5.1 and procedures established by the Administrator. In the event no such election is made by the Participant or if Employer desires to direct Employer Discretionary Contributions to a particular Participant sub-account, the Employer, in its sole discretion, may determine which sub-account will be credited with such Employer Discretionary Contribution. In the event the Employer does not designate which Participant sub-account shall be credited, such Employer Discretionary Contribution shall be credited to a lump-sum Separation/Retirement sub-account.

6.4 Substantially Equal Annual Installments

(a) The amount of the substantially equal payments shall be determined by multiplying the Participant’s Account or sub-account by a fraction, the denominator of which in the first year of payment equals the number of years over which benefits are to be paid, and the numerator of which is one (1). The amounts of the payments for each succeeding year shall be determined by multiplying the Participant’s Account or sub-account as of the applicable anniversary of the payout by a fraction, the denominator of which equals the number of remaining years over which benefits are to be paid, and the numerator of which is one (1).

To the extent permitted by Code Section 409A, and notwithstanding any provision of the Plan to the contrary, the Administrator, in its sole discretion, may elect to (i) accelerate the time or form of payment of a benefit owed to a Participant hereunder in accordance with the terms and subject to the conditions of Treasury Regulations Section 1.409A-3(j)(4), or (ii) delay the time of payment of a benefit owed to a Participant hereunder in accordance with the terms and subject to the conditions of Treasury Regulations Section 1.409A-2(b)(7). By way of example, and at the sole discretion of the Administrator, if a Participant’s entire Account balance is less than the applicable Code Section 402(g) annual limit, the Employer may distribute the Participant’s Account in a lump sum provided that the distribution results in the termination of the participant’s entire interest in the Plan, subject to the plan aggregation rules of Code Section 409A and regulations thereunder. By way of example, the Administrator may permit such acceleration of the time or schedule of a payment under the arrangement to an individual other than a Participant as may be necessary to fulfill a domestic relations order (as defined in Code Section 414(p)(1)(B)).

6.10 Unforeseeable Emergency

The Administrator may permit an early distribution of part or all of any deferred amounts; provided, however, that such distribution shall be made only if the Administrator, in its sole discretion, determines that the Participant, or the Participant’s beneficiary, has experienced an Unforeseeable Emergency. An Unforeseeable Emergency is defined as a severe financial hardship resulting from an illness or accident of the Participant, the Participant’s spouse, the Participant’s beneficiary, or a dependent (as defined in Code Section 152(a)) of the Participant, loss of the Participant’s property due to casualty or other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the control of the Participant. If an Unforeseeable Emergency is determined to exist, a distribution may not exceed the amounts necessary to satisfy such emergency plus amounts necessary to pay taxes reasonably anticipated as a result of the distribution, after taking into account the extent to which such hardship is or may be relieved through reimbursement or compensation by insurance or otherwise or by liquidation of the Participant’s assets (to the extent the liquidation of such assets would not itself cause severe financial hardship). Upon a distribution to a Participant under this Section 6.10, the Participant’s Deferrals shall cease and no further Deferrals shall be made for such Participant for the remainder of the Plan Year and one (1) subsequent Plan Year.

6.11 Distributions to Specified Employee

Notwithstanding anything herein to the contrary, if any Participant is a Specified Employee upon a Separation from Service for any reason other than death, distributions to such Participant shall commence no earlier than six months following Separation from Service (or, if earlier, the date of death of the Participant) and no later than eight months following Separation from Service. If distributions are to be made in annual installments, the second installment and all those thereafter will be made on the applicable anniversaries of the date on which the Participant’s initial installment was payable.

6.12 Minimum Distribution

Notwithstanding any provision to the contrary, if the balance of a Participant’s Account or sub-account at the time of a distribution event is $25,000 or less, then the Participant shall be paid his or her Account or sub-account as a single lump sum.

6.13 Form of Payment

All distributions shall be made in the form of cash.

6.14 Distributions upon a Change-in-Control

Notwithstanding any distribution election to the contrary, if a Change-in-Control occurs and a Participant incurs a Separation from Service during the period beginning on the date of the Change-in-Control and ending on the second anniversary of the Change-in-Control, then the remaining amount of the Participant’s vested Account shall be paid to the Participant or his or her beneficiary in a single lump-sum payment as soon as administratively possible, but no later than ninety (90) days, following such Change-in-Control.

Article 7 Beneficiaries

7.1 Beneficiaries

Each Participant may from time to time designate one or more persons (who may be any one or more members of such person’s family or other persons, administrators, trusts, foundations or other entities) as his or her beneficiary under the Plan. Such designation shall be made in a form prescribed by the Administrator. Each Participant may at any time and from time to time, change any previous beneficiary designation, without notice to or consent of any previously designated beneficiary, by amending his or her previous designation in a form prescribed by the Administrator. If the beneficiary does not survive the Participant (or is otherwise unavailable to receive payment), or if no beneficiary is validly designated then the amounts payable under this Plan shall be paid to the Participant’s estate. If more than one person is the beneficiary of a deceased Participant, each such person shall receive a pro rata share of any death benefit payable unless otherwise designated in the applicable form. If a beneficiary who is receiving benefits dies, all benefits that were payable to such beneficiary shall then be payable to the estate of that beneficiary.

7.2 Lost Beneficiary

All Participants and beneficiaries shall have the obligation to keep the Administrator informed of their current address until such time as all benefits due have been paid. If a Participant or beneficiary cannot be located by the Administrator exercising due diligence, then, in its sole discretion, the Administrator may presume that the Participant or beneficiary is deceased for purposes of the Plan and all unpaid amounts (net of due diligence expenses) owed to the Participant or beneficiary shall be paid accordingly or, if a beneficiary cannot be so located, then such amounts may be forfeited. Any such presumption of death shall be final, conclusive and binding on all parties.

Article 8 Funding

8.1 Prohibition against Funding

Should any investment be acquired in connection with the liabilities assumed under this Plan, it is expressly understood and agreed that the Participants and beneficiaries shall not have any right with respect to, or claim against, such assets nor shall any such purchase be construed to create a trust of any kind or a fiduciary relationship between the Employer and the Participants, their beneficiaries or any other person. Any such assets shall be and remain a part of the general, unpledged, unrestricted assets of the Employer, subject to the claims of its general creditors. It is the express intention of the parties hereto that this arrangement shall be unfunded for tax purposes and for purposes of Title I of the ERISA. Each Participant and beneficiary shall be required to look to the provisions of this Plan and to the Employer itself for enforcement of any and all benefits due under this Plan, and to the extent any such person acquires a right to receive payment under this Plan, such right shall be no greater than the right of any unsecured general creditor of the Employer. The Employer or the Trust shall be designated the owner and beneficiary of any investment acquired in connection with its obligation under this Plan.

8.2 Deposits in Trust

Notwithstanding Section 8.1, or any other provision of this Plan to the contrary, the Employer may deposit into the Trust any amounts it deems appropriate to pay the benefits under this Plan. The amounts so deposited may include all contributions made pursuant to a Deferral Election by a Participant, all Employer Matching Contributions and any Employer Discretionary Contributions.

8.3 Withholding of Employee Contributions

The Administrator is authorized to make any and all necessary arrangements with the Employer in order to withhold the Participant’s Deferrals under Section 3.1 hereof from his or her Compensation. The Administrator shall determine the amount and timing of such withholding.

Article 9 Claims Administration

9.1 General

If a Participant, beneficiary or his or her representative is denied all or a portion of an expected Plan benefit for any reason and the Participant, beneficiary or his or her representative desires to dispute the decision of the Administrator, he or she must file a written notification of his or her claim with the Administrator.

9.2 Claims Procedure

Upon receipt of any written claim for benefits, the Administrator shall be notified and shall give due consideration to the claim presented. If any Participant or beneficiary claims to be entitled to benefits under the Plan and the Administrator determines that the claim should be denied in whole or in part, the Administrator shall, in writing, notify such claimant within ninety (90) days (forty-five (45) days if the claim is on account of Disability) of receipt of the claim that the claim has been denied. The Administrator may extend the period of time for making a determination with respect to any claim for a period of up to ninety (90) days (thirty (30) days if claim is on account of Disability), provided that the Administrator determines that such an extension is necessary because of special circumstances and notifies the claimant, prior to the expiration of the initial ninety (90) day (or forty-five (45) day) period, of the circumstances requiring the extension of time and the date by which the Plan expects to render a decision. If the claim is denied to any extent by the Administrator, the Administrator shall furnish the claimant with a written notice setting forth:

(a) the specific reason or reasons for denial of the claim;

(b) a specific reference to the Plan provisions on which the denial is based;

(c) a description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material or information is necessary; and

(d) an explanation of the provisions of this Article.

Under no circumstances shall any failure by the Administrator to comply with the provisions of this Section 9.2 be considered to constitute an allowance of the claimant’s claim.

9.3 Right of Appeal

A claimant who has a claim denied wholly or partially under Section 9.2 may appeal to the Administrator for reconsideration of that claim. A request for reconsideration under this Section must be filed by written notice within sixty (60) days (one-hundred and eighty (180) days if the claim is on account of Disability) after receipt by the claimant of the notice of denial under Section 9.2.

9.4 Review of Appeal

Upon receipt of an appeal the Administrator shall promptly take action to give due consideration to the appeal. Such consideration may include a hearing of the parties involved, if the Administrator feels such a hearing is necessary. In preparing for this appeal, the claimant shall be given the right to review pertinent documents and the right to submit in writing a statement of issues and comments. After consideration of the merits of the appeal, the Administrator shall issue a written decision, which shall be binding on all parties. The decision shall specifically state its reasons and pertinent Plan provisions on which it relies. The Administrator’s decision shall be issued within sixty (60) days (forty-five (45) days if the claim is on account of Disability) after the appeal is filed, except that the Administrator may extend the period of time for making a determination with respect to any claim for a period of up one-hundred and twenty (120) days (ninety (90) days if the claim is on account of Disability), provided that the Administrator determines that such an extension is necessary because of special circumstances and notifies the claimant, prior to the expiration of the initial one-hundred and twenty (120) day (or, if the claim is on account of Disability, initial ninety (90) day) period, of the circumstances requiring the extension of time and the date by which the Plan expects to render a decision. Under no circumstances shall any failure by the Administrator to comply with the provisions of this Section 9.4 be considered to constitute an allowance of the claimant’s claim. In the case of a claim on account of Disability: (i) the review of the denied claim shall be conducted by an employee who is neither the individual who made the initial determination or a subordinate of such person; and (ii) no deference shall be given to the initial determination. For issues involving medical judgment, the employee must consult with an

independent health care professional who may not be the health care professional who rendered the initial claim.

9.5 Designation

The Administrator may designate any other person of its choosing to make any determination otherwise required under this Article. Any person so designated shall have the same authority and discretion granted to the Administrator hereunder.

Article 10 General Provisions

10.1 Administrator

(a) The Administrator is expressly empowered to limit the amount of Compensation that may be deferred; to deposit amounts into the Trust in accordance with Section 8.2 hereof; to interpret the Plan, and to determine all questions arising in the administration, interpretation and application of the Plan; to employ actuaries, accountants, counsel, and other persons it deems necessary in connection with the administration of the Plan; to request any information from the Employer it deems necessary to determine whether the Employer would be considered insolvent or subject to a proceeding in bankruptcy; and to take all other necessary and proper actions to fulfill its duties as Administrator.

(b) The Administrator shall not be liable for any actions by it hereunder, unless due to its own negligence, willful misconduct or lack of good faith.

(c) The Administrator shall be indemnified and saved harmless by the Employer from and against all personal liability to which it may be subject by reason of any act done or omitted to be done in its official capacity as Administrator in good faith in the administration of the Plan and Trust, including all expenses reasonably incurred in its defense in the event the Employer fails to provide such defense upon the request of the Administrator. The Administrator is relieved of all responsibility in connection with its duties hereunder to the fullest extent permitted by law, short of breach of duty to the beneficiaries.

10.2 No Assignment

Benefits or payments under this Plan shall not be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, or garnishment by creditors of the Participant or the Participant’s beneficiary, whether voluntary or involuntary, and any attempt to so anticipate, alienate, sell, transfer, assign, pledge, encumber, attach or garnish the same shall not be valid, nor shall any such benefit or payment be in any way liable for or subject to the debts, contracts, liabilities, engagement or torts of any Participant or beneficiary, or any other person entitled to such benefit or payment pursuant to the terms of this Plan, except to such extent as may be required by law. If any Participant or beneficiary or any other person entitled to a benefit or payment pursuant to the terms of this Plan becomes bankrupt or attempts to anticipate, alienate, sell, transfer, assign, pledge, encumber, attach or garnish any benefit or payment under this Plan, in whole or in part, or if any attempt is made to subject any such benefit or payment, in whole or in part, to the debts, contracts, liabilities, engagements or torts of the Participant or beneficiary or any other person entitled to any such benefit or payment pursuant to the terms of this Plan, then such benefit or payment, in the discretion of the Administrator, shall cease and terminate with respect to such Participant or beneficiary, or any other such person.

10.3 No Employment Rights

Participation in this Plan shall not be construed to confer upon any Participant the legal right to be retained in the employ of the Employer, or give a Participant or beneficiary, or any other person, any right to any payment whatsoever, except to the extent of the benefits provided for hereunder. Each Participant shall remain subject to discharge to the same extent as if this Plan had never been adopted.

10.4 Incompetence

If the Administrator determines that any person to whom a benefit is payable under this Plan is incompetent by reason of physical or mental disability, the Administrator shall have the power to cause the

payments becoming due to such person to be made to another for his or her benefit without responsibility of the Administrator or the Employer to see to the application of such payments. Any payment made pursuant to such power shall, as to such payment, operate as a complete discharge of the Employer, the Administrator and the Trustee.

10.5 Identity

If, at any time, any doubt exists as to the identity of any person entitled to any payment hereunder or the amount or time of such payment, the Administrator shall be entitled to hold such sum until such identity or amount or time is determined or until an order of a court of competent jurisdiction is obtained. The Administrator shall also be entitled to pay such sum into court in accordance with the appropriate rules of law. Any expenses incurred by the Employer, Administrator, and Trust incident to such proceeding or litigation shall be charged against the Account of the affected Participant.

10.6 Other Benefits

The benefits of each Participant or beneficiary hereunder shall be in addition to any benefits paid or payable to or on account of the Participant or beneficiary under any other pension, disability, annuity or retirement plan or policy whatsoever.

10.7 Expenses

All expenses incurred in the administration of the Plan, whether incurred by the Employer or the Plan, shall be paid by the Employer.

10.8 Insolvency

Should the Employer be considered insolvent (as defined by the Trust), the Employer, through its Board and chief executive officer, shall give immediate written notice of such to the Administrator of the Plan and the Trustee. Upon receipt of such notice, the Administrator or Trustee shall cease to make any payments to Participants who were Employees of the Employer or their beneficiaries and shall hold any and all assets attributable to the Employer for the benefit of the general creditors of the Employer.

10.9 Amendment or Modification

The Employer may, at any time, in its sole discretion, amend or modify the Plan in whole or in part, except that no such amendment or modification shall have any retroactive effect to reduce any amounts allocated to a Participant’s Accounts, and provided that such amendment or modification complies with Code Section 409A and related regulations thereunder.

10.10 Plan Suspension

The Employer further reserves the right to suspend the Plan in whole or in part, except that no such suspension shall have any retroactive effect to reduce any amounts allocated to a Participant’s Accounts, and provided that the distribution of the vested Participant Accounts shall not be accelerated but shall be paid at such time and in such manner as determined under the terms of the Plan immediately prior to suspension as if the Plan had not been suspended.

10.11 Plan Termination

The Employer further reserves the right to terminate the Plan in whole or in part, in the following manner, except that no such termination shall have any retroactive effect to reduce any amounts allocated to a Participant’s Accounts, and provided that such termination complies with Code Section 409A and related regulations thereunder:

(a) The Employer, in its sole discretion, may terminate the Plan and distribute all vested Participants’ Accounts no earlier than twelve (12) calendar months from the date of the Plan termination and no later than twenty-four (24) calendar months from the date of the Plan termination, provided however that all other similar arrangements are also terminated by the Employer for any affected Participant and no other similar arrangements are adopted by the Employer for any affected Participant within a three (3) year period from the date of termination; or

(b) The Employer may decide, in its sole discretion, to terminate the Plan in the event of a corporate dissolution taxed under Code Section 331, or with the approval of a bankruptcy court, provided that the Participants vested Account balances are distributed to Participants and are included in the Participants’ gross income in the latest of: (i) the calendar year in which the termination occurs; (ii) the calendar year in which the amounts deferred are no longer subject to a substantial risk of forfeiture; or (iii) the first calendar year in which payment is administratively practicable.

10.12 Plan Termination due to a Change-in-Control

The Employer may decide, in its discretion, to terminate the Plan in the event of a Change-in-Control and distribute all vested Participants Account balances no earlier than thirty (30) days prior to the Change-in-Control and no later than twelve (12) months after the effective date of the Change-in-Control, provided however that the Employer terminates all other similar arrangements for any affected Participant.

10.13 Construction

All questions of interpretation, construction or application arising under or concerning the terms of this Plan shall be decided by the Administrator, in its sole and final discretion, whose decision shall be final, binding and conclusive upon all persons.

10.14 Governing Law

This Plan shall be governed by, construed and administered in accordance with the applicable provisions of ERISA, Code Section 409A, and any other applicable federal law, provided, however, that to the extent not preempted by federal law this Plan shall be governed by, construed and administered under the laws of the State of Delaware, other than its laws respecting choice of law.

10.15 Severability

If any provision of this Plan is held invalid or unenforceable, its invalidity or unenforceability shall not affect any other provision of this Plan and this Plan shall be construed and enforced as if such provision had not been included therein. If the inclusion of any Employee (or Employees) as a Participant under this Plan would cause the Plan to fail to comply with the requirements of sections 201(2), 301(a)(3) and 401(a)(1) of ERISA, then the Plan shall be severed with respect to such Employee or Employees, who shall be considered to be participating in a separate arrangement.

10.16 Headings

The Article headings contained herein are inserted only as a matter of convenience and for reference and in no way define, limit, enlarge or describe the scope or intent of this Plan nor in any way shall they affect this Plan or the construction of any provision thereof.

10.17 Terms

Capitalized terms shall have meanings as defined herein. Singular nouns shall be read as plural, masculine pronouns shall be read as feminine, and vice versa, as appropriate.

10.18 Code Section 409A Fail Safe Provision

If any provision of this Plan violates Code Section 409A, the regulations promulgated thereunder, regulatory interpretations, announcements or mandatory judicial precedent construing Code Section 409A (collectively “Applicable Law”), then such provision shall be void and have no effect. At all times, this Plan shall be interpreted in such manner that it complies with Applicable Law.
