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 also established Aspen Capital Management, Ltd and other related entities (collectively, “ACM”) to leverage our existing underwriting franchise, increase our operational flexibility in the capital markets and provide investors direct access to our underwriting expertise. 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, 2015 are not necessarily indicative of the results that may be expected for the year ended December 31, 2015. 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, 2014 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, 2014 contained in the Company’s Annual Report on Form 10-K filed with the United States Securities and Exchange Commission on February 23, 2015 (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.

Accounting Pronouncements Not Yet Adopted

On January 5, 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-01, “Income Statement - Extraordinary and Unusual Items (Subtopic 225-20) - Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items” which eliminates from U.S. GAAP the requirement for an entity to separately classify, present and disclose extraordinary events and transactions as part of FASB’s initiative to reduce complexity in accounting standards. ASU 2015-01 is effective for fiscal years beginning after December 15, 2015 and the Company may apply the amendments prospectively or retrospectively to all prior periods presented in the financial statements. Early application is permitted provided the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect this ASU to have a material impact on its consolidated financial statements.

On February 18, 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810) - Amendments to the Consolidation Analysis” which includes amendments that change the analysis that an entity must perform to determine whether it should consolidate certain types of legal entities. ASU 2015-02 is effective for fiscal years beginning after December 15, 2015. The Company does not expect this ASU to have a material impact on its consolidated financial statements.


3.	Reclassifications from Accumulated Other Comprehensive Income

The following table sets out the components of the Company’s accumulated other comprehensive income (“AOCI”) that are reclassified into the unaudited condensed consolidated statement of operations for the three months ended March 31, 2015 and 2014:

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, 2015 and 2014, respectively:



	Three Months Ended March 31,
	2015			2014
	($ in millions, except share and per share amounts)

Net income	$	128.0		$	120.4
Preference share dividends	(9.5		)	(9.5		)
Net profit attributable to non-controlling interest	—			(0.1		)
Basic and diluted net income available to ordinary shareholders	118.5			110.8
Ordinary shares:
Basic weighted average ordinary shares	62,159,303			65,289,351
Weighted average effect of dilutive securities⁽¹⁾	1,373,359			1,276,539
Total diluted weighted average ordinary shares	63,532,662			66,565,890
Earnings per ordinary share:
Basic	$	1.91		$	1.70
Diluted	$	1.87		$	1.66


⁽¹⁾	Dilutive securities comprise: employee options, restricted share units and performance shares associated with the Company’s long term incentive plan, employee share purchase plans and director restricted stock units and options as described in Note 14.

Dividends. On April 22, 2015, the Company’s Board of Directors (“Board of Directors”) declared the following quarterly dividends:



	Dividend		Payable on:	Record Date:
Ordinary shares	$	0.21	May 27, 2015	May 8, 2015
7.401% preference shares	$	0.462563	July 1, 2015	June 15, 2015
7.250% preference shares	$	0.4531	July 1, 2015	June 15, 2015
5.95% preference shares	$	0.3719	July 1, 2015	June 15, 2015


5.	Segment Reporting

The Company has two reporting business segments: Insurance and Reinsurance. In arriving at these reporting segments, the Company considered similarities in economic characteristics, products, customers, distribution, the regulatory environment of the Company’s operating segments and quantitative thresholds. 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 and facultative), casualty reinsurance (U.S. treaty, international treaty and global facultative) and specialty reinsurance (credit and surety, agriculture, marine, aviation, engineering and other specialty). ACM forms part of our property catastrophe reinsurance line of business as it currently focuses 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 2014 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

Insurance Segment. The insurance segment consists of property and casualty insurance (including the programs business which was previously reported separately), 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 2014 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, 2015 and 2014:



	Three Months Ended March 31, 2015

Other-than-temporary Impairments. A security is potentially impaired when its fair value is below its amortized cost. The Company reviews its available for sale fixed income and equity portfolios on an individual security basis for potential other-than-temporary impairment (“OTTI”) each quarter based on criteria including issuer-specific circumstances, credit ratings actions and general macro-economic conditions. For a more detailed description of OTTI, please refer to Note 2(c) of the “Notes to the Audited Consolidated Financial Statements” in the Company’s 2014 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission. There was no OTTI charge recognized for the three months ended March 31, 2015 (2014 — $Nil).

The Company classifies these financial instruments as held for trading as this most closely reflects the facts and circumstances of the investments held.

Catastrophe Bonds. The Company has invested in catastrophe bonds with a total value of $32.8 million as of March 31, 2015. The bonds receive quarterly interest payments based on variable interest rates with scheduled maturities ranging from 2016 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 United States, Canada, the North Atlantic, Japan or Australia.

Other Investments. 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 as addressed by the guidance in ASC 810-10, Consolidation. However, having considered the provisions of ASC 810-10, 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 and adjustments to the carrying value of this investment are made based on the Company’s share of capital including share of income and expenses, which is provided in the quarterly management accounts. The adjusted carrying value approximates fair value.

In January 2015, the Company established, along with seven other insurance companies, a micro-insurance venture consortium and micro-insurance incubator ("MVI"), domiciled in Bermuda. The MVI will be a social impact organization that will provide micro-insurance products to assist global emerging consumers. The Company's initial investment in the MVI was $0.8 million.

The table below shows the Company’s investments in the Microinsurance Venture and Chaspark for the three months ended March 31, 2015:

Fixed Income Securities. The scheduled maturity distribution of available for sale fixed income securities as at March 31, 2015 and December 31, 2014 is set forth below. Actual maturities may differ from contractual maturities because issuers of securities may have the right to call or prepay obligations with or without call or prepayment penalties.

Guaranteed Investments. As at March 31, 2015, the Company held $2.4 million (December 31, 2014 — $2.5 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, rated A3 and Caa3 (December 31, 2014 — two municipal securities, rated A3 and Caa3). 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, 2015, the Company had two investments in two variable interest entities (“VIE”), 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, 2015, there was no change in the value of the Company’s investment in Chaspark (March 31, 2014 — $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 business through retrocession agreements which are collateralized and funded by Silverton through the issuance of a series of loan notes. Silverton is a non-rated insurer and the risks are fully collateralized by way of funds held in trust for the benefit of Aspen Bermuda.

The proceeds of $65.0 million (of which $50.0 million was issued to third parties) from the issuance of Silverton’s Series 2014-1 Participating Notes on December 27, 2013 (“2014 Loan Notes”) were deposited into a collateral account to fund Silverton’s obligations under a retrocession property quota share agreement entered into with Aspen Bermuda effective January 1, 2014. The holders of the 2014 Loan Notes participate in any profit or loss generated by Silverton attributable to the operations of Silverton’s Series 2014-1 Segregated Account. Any existing value of the 2014 Loan Notes is being returned to the noteholders in installments after the expiration of the risk period of the retrocession agreement issued by Silverton for the related series with the final payment being contractually due on the September 16, 2016 maturity date. The fair value of the 2014 Loan Notes as at March 31, 2015 was $89.2 million (of which $68.6 million was due to external investors). During the first quarter of 2015, Silverton distributed $84.4 million (of which $64.8 million was distributed to external investors) to its noteholders. Of the remaining $3.8 million due to external investors, $0.7 million has been classified as a current liability in the Company’s consolidated financial statements with the balance of $3.1 million classified as long-term debt. The total aggregate unpaid balance of the 2014 Loan Notes held by third parties and those held by Aspen Holdings is $4.8 million. The Company’s maximum loss exposure to the 2014 Loan Notes is $1.1 million which is the fair value of its holdings as at March 31, 2015.

The proceeds of $85.0 million (of which $70.0 million was issued to third parties) from the issuance of Silverton’s Series 2015-1 Participating Notes on December 23, 2014 (“2015 Loan Notes”) were deposited into a collateral account to fund Silverton’s obligations under a retrocession property quota share agreement entered into with Aspen Bermuda effective January 1, 2015. The holders of the 2015 Loan Notes participate in any profit or loss generated by Silverton attributable to the

operations of Silverton’s Series 2015-1 Segregated Account. Any existing value of the 2015 Loan Notes will be returned to the noteholders after the expiration of the risk period of the retrocession agreement issued by Silverton for the related series with the final payment being contractually due on the September 18, 2017 maturity date. The fair value of the 2015 Loan Notes as at March 31, 2015 was $88.5 million (of which $72.9 million was held by external investors). The $72.9 million of the 2015 Loan Notes held by external investors is classified as long term debt in the Company’s consolidated financial statements. The total aggregate unpaid balance of the 2015 Loan Notes held by third parties and those held by Aspen Holdings is $88.5 million. The Company’s maximum loss exposure to the 2015 Loan Notes is $15.6 million which is the fair value of its holdings as at March 31, 2015.

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.

For further information regarding the loan notes attributable to the third-party investments in Silverton, refer to Note 8 of these unaudited condensed consolidated financial statements.


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.

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, 2015 and December 31, 2014, respectively:

Valuation of Fixed Income Securities. The Company’s fixed income securities are classified as either available for sale or trading and carried at fair value. As at March 31, 2015 and December 31, 2014, the Company’s fixed income securities were valued by pricing services, index providers or broker-dealers using standard market conventions. The market conventions utilize market quotations, market transactions in comparable instruments and various relationships between instruments including, but not limited to, yield to maturity, dollar prices and spread prices in determining value.

Independent Pricing Services and Index Providers. The underlying methodology used to determine the fair value of securities in the Company’s available for sale and trading portfolios by the pricing services and index providers the Company uses is very similar. Pricing services will gather observable pricing inputs from multiple external sources, including buy and sell-side contacts and broker-dealers, in order to develop their internal prices. Index providers are those firms which provide prices for a range of securities within one or more asset classes, typically using their own in-house market makers (traders) as the primary pricing source for the indices, although ultimate valuations may also rely on other observable data inputs to derive a dollar price for all index-eligible securities. Index providers without in-house trading desks will function similarly to a pricing service in that they will gather their observable pricing inputs from multiple external sources. All prices for the Company’s securities attributed to index providers are for an individual security within the respective indices.

Pricing services and index providers provide pricing for less complex, liquid securities based on market quotations in active markets. Pricing services and index providers supply prices for a broad range of securities including those for actively traded securities, such as Treasury and other Government securities, in addition to those that trade less frequently or where valuation includes reference to credit spreads, pay down and pre-pay features and other observable inputs. These securities include Government Agency, Municipals, Corporate and Asset-Backed Securities.

For securities that may trade less frequently or do not trade on a listed exchange, these pricing services and index providers may use matrix pricing consisting of observable market inputs to estimate the fair value of a security. These observable market inputs include: reported trades, benchmark yields, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data, and industry and economic factors. Additionally, pricing services and index providers may use a valuation model such as an option adjusted spread model commonly used for estimating fair values of mortgage-backed and asset-backed securities. Neither the Company, nor its index providers, derives dollar prices using an index as a pricing input for any individual security.

Broker-Dealers. The Company obtains quotes from broker-dealers who are active in the corresponding markets when prices are unavailable from independent pricing services or index providers. Generally, broker-dealers value securities through their trading desks based on observable market inputs. Their pricing methodologies include mapping securities based on trade data, bids or offers, observed spreads and performance of newly issued securities. They may also establish pricing through observing secondary trading of similar securities. 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, 2015, the Company obtained an average of 2.0 quotes per fixed income investment, consistent with 2.0 quotes as at December 31, 2014. Pricing sources used in pricing fixed income investments as at March 31, 2015 and December 31, 2014 were as follows:



	As at March 31, 2015		As at December 31, 2014
Index providers	82	%	84	%

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.

Fixed Income Securities. The Company’s fixed income securities are traded on the over-the-counter (“OTC”) market based on prices provided by one or more market makers in each security. Securities such as U.S. Government, U.S. Agency, 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.

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 include 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 include 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 are not 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, 2015, the Company obtained an average of 4.0 quotes per equity investment, compared to 4.0 quotes as at December 31, 2014. Pricing sources used in pricing equities as at March 31, 2015 and December 31, 2014 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.

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. 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. During the fourth quarter of 2014, Silverton issued an additional $85.0 million ($70.0 million third-party funded) loan notes with a maturity date of September 18, 2017. 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 between Aspen Bermuda and Silverton. 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 are the most significant unobservable input. An increase in reserves for losses would normally result in a decrease in the fair value of the loan notes while a decrease in reserves would normally result in an increase in the fair value of the loan notes. The observable and unobservable inputs used to determine the fair value of the 2015-1 Loan Notes and 2014-1 Loan Notes as at March 31, 2015 and December 31, 2014 are presented in the table below:



At March 31, 2015		Fair Value Level 3		Valuation Method	Observable (O) and Unobservable (U) inputs	Low		High
	($ in millions)					($ in millions)
Loan notes held by third parties		$	76.7	Internal Valuation Model	Gross premiums written (O)	$	37.6	$	39.6
					Reserve for losses (U)	$	1.1	$	4.4
					Contract period (O)	N/A		365 days
					Initial value of issuance (O)	$	120.0	$	120.0



At December 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		$	138.6	Internal Valuation Model	Gross premiums written (O)	$	—	$	40.0
					Reserve for losses (U)	$	—	$	4.6
					Contract period (O)	N/A		365 days
					Initial value of issuance (O)	$	120.0	$	120.0

The observable and unobservable inputs represent the potential variation around the inputs used in the valuation model. The contract period is defined in the Silverton loan agreements and the initial value represents the funds received from third parties.


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, 2015 were 20.0% (December 31, 2014 — 18.6%) with Munich Re rated AA- by S&P, 18.9% (December 31, 2014 — 27.3%) with Lloyd’s syndicates rated A+ by S&P and 7.9% (December 31, 2014 — 8.4%) with Arch Re which is rated A+ by S&P.

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, 2015, the Company held foreign exchange contracts that were not designated as hedging under ASC 815 with an aggregate notional value of $362.3 million (December 31, 2014 — $403.4 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, 2015, the impact of foreign exchange contracts on net income was a charge of $4.6 million (March 31, 2014 — gain of $3.0 million).

As at March 31, 2015, the Company held foreign exchange contracts that were designated as hedging under ASC 815 with an aggregate notional value of $84.6 million (December 31, 2014 — $135.8 million). The foreign exchange contracts are recorded as derivatives at fair value in the balance sheet with the effective portion recorded in other comprehensive income and the ineffective portion recorded as a change in fair value of derivatives in the statement of operations. The contracts are considered to be effective and therefore, for the three months ended March 31, 2015, the movement in other comprehensive income representing the effective portion was a net unrealized loss of $2.4 million (March 31, 2014 — $Nil).

As the foreign exchange contracts settle, the realized gain or loss is reclassified from other comprehensive income into general, administration and corporate expenses of the statement of operations and other comprehensive income. For the three months ended March 31, 2015 the realized loss recognized within general, administration and corporate expenses for settled foreign exchange contracts was $2.8 million (March 31, 2014 — $Nil).

Interest Rate Swaps. As at March 31, 2015, the Company held fixed for floating interest rate swaps with a total notional amount of $951.3 million (December 31, 2014 — $951.3 million) that are due to mature between November 26, 2015 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, 2015, there was a charge in respect of the interest rate swaps of $3.2 million (March 31, 2014 — charge of $1.9 million).

As at March 31, 2015, cash collateral with a fair value of $19.5 million was held by the Company’s counterparties to support the current valuation of the interest rate swaps (December 31, 2014 — $22.3 million). As at March 31, 2015, no non-cash collateral was transferred to the Company by its counterparties (December 31, 2014 — $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, 2015, no amount was recorded in the consolidated balance sheet for the pledged assets.

Ordinary Shares. The following table summarizes transactions in the Company’s ordinary shares during the three months ended March 31, 2015:



	Number of Ordinary Shares
Ordinary shares in issue at December 31, 2014	62,017,368
Ordinary share transactions in the three months ended March 31, 2015
Ordinary shares issued to employees under the 2003 and 2013 share incentive plans and/or 2008 share purchase plan	485,466
Ordinary shares issued to non-employee directors	6,806
Ordinary shares repurchased	(787,138	)
Ordinary shares in issue at March 31, 2015	61,722,502

Ordinary Share Repurchases. On February 5, 2015, the Company and the Board of Directors agreed a new share repurchase authorization program of $500.0 million. The total share repurchase authorization, which was effective immediately through February 6, 2017, 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 under a Rule 10b5-1 plan, the Company acquired and cancelled 787,138 ordinary shares for the three months ended March 31, 2015. The total consideration paid was $36.5 million with an average price of $46.32 per ordinary share. Under open market repurchases, the Company acquired and cancelled 770,505 ordinary shares for the three months ended March 31, 2014. The total consideration paid for the three months ended March 31, 2014 was $30.9 million with an average price of $40.08 per ordinary share.

Rights Agreement. On April 17, 2014, the Board of Directors 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 would have allowed 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 became exercisable. The Rights could not be exercisable until 10 business days after the public announcement that a person or group 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). The

Rights could have been redeemed at any time at the discretion of the Board of Directors. As of March 31, 2015, no Rights were exercisable or exercised. The Rights Agreement expired on April 16, 2015.


14.	Share-Based Payments

The Company has issued options and other equity incentives under three arrangements: the employee incentive plans, the non-employee director plan and the employee share purchase plans. 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 2013 Share Incentive Plan (the “2013 Share Incentive Plan”). The total number of ordinary shares that may be issued under the 2013 Share Incentive Plan is 2,845,683 ordinary shares, which includes 595,683 ordinary shares available to grant under the 2003 Share Incentive Plan as of February 25, 2013. The number of ordinary shares that may be issued under the 2013 Share Incentive Plan is adjusted per the number of awards that may be forfeited under the 2003 Share Incentive Plan. 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 exercise 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, 2015 (2014 — Nil) and 83,938 options were exercised and shares issued in the three months ended March 31, 2015 (2014 — 19,579). No charges against income were made in respect of employee options for the three months ended March 31, 2015 (2014 — $Nil).

Restricted share units (“RSUs”) granted to employees typically vest over a three-year period based on continued service. Some of the RSU grants vest at year-end, while others vest on the anniversary of the date of grant or when the Compensation Committee of the Board of Directors agrees to deliver the RSUs. The fair value of the RSUs is based on the closing price on the date of the grant adjusted for illiquidity and is expensed through the income statement evenly over the vesting period. In the three months ended March 31, 2015, the Company granted 238,315 RSUs to its employees (2014 — Nil). Compensation costs charged against income in respect of RSUs for the three months ended March 31, 2015 were $4.7 million (2014 — $2.8 million).

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 vesting on the first anniversary of the date of grant. On February 5, 2015 (with a grant date of February 9, 2015), the Board of Directors approved a total of 27,620 RSUs for the non-employee directors (2014 — 27,180 RSUs) and 12,154 RSUs to the Chairman (February 10, 2014 — 13,590). Compensation costs charged against income in respect of non-employee director RSUs for the three months ended March 31, 2015 were $0.3 million (2014 — $0.4 million).

The total fair value adjustment for all RSUs for the three months ended March 31, 2015 was $0.3 million (2014 — $0.6 million). The total tax credit recognized by the Company in relation to RSUs in the three months ended March 31, 2015 was $1.1 million (2014 — $0.6 million).

Performance Shares. During the three months ended March 31, 2015, the Company granted 277,585 performance shares to employees (three months ended March 31, 2014 — Nil). The performance shares will be subject to a three-year vesting period with a separate annual diluted book value per share (“BVPS”) growth test for each year, adjusted to add back ordinary dividends. One-third of the grant will be eligible for vesting each year based on a formula, and will only be issuable at the end of the three-year period.

If the diluted BVPS growth achieved in 2015 is:


•	less than 5.6%, then the portion of the performance shares subject to the vesting conditions in such year will be forfeited (i.e., one-third of the initial grant);


•	between 5.6% and 11.1%, then the percentage of the performance shares eligible for vesting in such year will be between 10% and 100% on a straight-line basis; or


•	between 11.1% and 22.2%, then the percentage of the performance shares eligible for vesting in such year will be between 100% and 200% on a straight-line basis.

In calculating BVPS for 2015, the entire movement in AOCI will be excluded. Interest rate movements and credit spread movements in AOCI can be fairly significant and impact growth in BVPS which management does not have any control over. The Compensation Committee also agreed that it will review the impact of any capital management actions undertaken during 2015, including share repurchases and special dividends, and consider whether any further adjustments to growth in BVPS

should be may be made in the context of such actions. The Compensation Committee further agreed to exclude from the calculation of BVPS for 2015 all transactional expenses incurred in connection with any transaction which, if consummated, would result in a change in control, including without limitation the cost of defending against any such transaction and any third-party legal and advisory costs. The Compensation Committee believes that it would not be appropriate for employee’s performance-related compensation to be impacted by these costs.

The Compensation Committee will determine the vesting conditions for the 2016 and 2017 portions of the grant in such years taking into consideration the market conditions and the Company’s business plans at the commencement of the years concerned. Notwithstanding the vesting criteria for each given year, if the shares eligible for vesting in 2016 and 2017 are greater than 100% for the portion of such year’s grant and the average diluted BVPS growth over such year and the preceding year is less than the average of the minimum vesting thresholds for such year and the preceding year, then only 100% (and no more) of the ordinary shares that are eligible for vesting in such year shall vest. Notwithstanding the foregoing, if in the judgment of the Compensation Committee the main reason for the BVPS metric in the earlier year falling below the minimum threshold is due to the impact of rising interest rates and bond yields, then the Compensation Committee may, in its discretion, disapply this limitation on 100% vesting.

The fair value of performance share awards is based on the value of the closing share price on the date of the grant adjusted for illiquidity 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, 2015 in respect of performance shares were $0.2 million (2014 — $1.5 million). The total tax recognized by the Company in relation to performance shares in the three months ended March 31, 2015 was a tax credit of $0.1 million (2014 — $0.4 million).

Phantom Shares. During the three months ended March 31, 2015, the Compensation Committee approved the grant of 135,651 phantom shares to its employees (2014 — Nil). The phantom shares are subject to a three-year vesting period with a separate annual diluted BVPS growth test for each year, in accordance with the test described above for the 2015 performance shares, with the difference being that any vested amount would be paid in cash in lieu of ordinary shares. As ordinary shares are not issued, the phantom shares have no dilutive effect.

The fair value of the phantom shares is based on the closing share price on the date of the grant adjusted for illiquidity, 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 ordinary shares, an adjustment is required each quarter to revalue the accumulated liability to the balance sheet date fair value. Compensation costs charged against income in the three months ended March 31, 2015 in respect of phantom shares were $0.9 million (2014 — $1.6 million) with a fair value adjustment for the three months ended March 31, 2015 of $1.1 million (2014 — $0.2 million). The total tax credit recognized by the Company in relation to phantom shares in the three months ended March 31, 2015 was $0.4 million (2014 — $0.2 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 the Company’s ordinary shares at a discounted price, subject to a further one year holding period. In respect of the 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 the Company’s ordinary shares at a discounted price. The purchase price will be eighty-five percent (85%) of the fair market value of an ordinary share on the offering date which may be adjusted upon changes in capitalization of the Company. Under the ESPP, 52,452 ordinary shares were issued during the three months ended March 31, 2015 (2014 — 9,994 shares). Compensation costs charged against income in the three months ended March 31, 2015 in respect of the ESPP were $0.3 million (2014 — $0.1 million).

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 and investments as at March 31, 2015 in the amount of $417.9 million (December 31, 2014 — $411.9 million).

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, 2015 was £0.4 million (December 31, 2014 — £0.4 million). This is not available for distribution by the Company for the payment of dividends.

Letters of Credit Facility. On June 30, 2014, Aspen Bermuda and Citibank Europe plc (“Citi Europe”) replaced an existing letter of credit facility, dated July 30, 2012, in a maximum aggregate amount of up to $950.0 million (the “LOC Facility”) comprised of two maturity tranches (Tranche I with a limit of $650.0 million and Tranche II with a limit of $300.0 million) which expired on its own terms on June 30, 2014. The LOC Facility was replaced with a new letter of credit facility in a maximum aggregate amount of up to $575.0 million (the “New LOC Facility”). Under the New LOC Facility, which will expire on June 30, 2016, Aspen Bermuda will pay to Citi Europe (a) a letter of credit fee based on the available amounts of each letter of credit and (b) a commitment fee, which varies based upon usage, on the unutilized portion of the New LOC Facility. Aspen Bermuda will also pay interest on the amount drawn by any beneficiary under a credit provided under the New LOC Facility at a rate per annum of LIBOR plus 1% (plus reserve asset costs, if any) from the date of drawing until the date of reimbursement by Aspen Bermuda. The New LOC Facility is used to secure obligations of Aspen Bermuda to its policyholders. In addition to the New LOC Facility, we also use regulatory trusts to secure our obligations to policyholders.

The terms of a Pledge Agreement between Aspen Bermuda and Citi Europe (pursuant to an Assignment Agreement dated October 11, 2006) dated January 17, 2006, as amended, were also amended on June 30, 2014 to change the types of securities or other assets that are acceptable as collateral under the New LOC Facility. All other agreements relating to Aspen Bermuda’s LOC Facility, which now apply to the New LOC Facility with Citi Europe, as previously filed with the United States Securities and Exchange Commission, remain in full force and effect.

On December 18, 2014, Aspen Bermuda and Citi Europe entered into an amended and restated pledge agreement (“Pledge Agreement”) to, among other things, (i) change the types of securities or other assets that qualify as collateral pledged under the Pledge Agreement, (ii) provide Aspen Bermuda the right to give certain directions or entitlement orders to The Bank of New York Mellon (“BNY Mellon”), as securities intermediary, relating to the collateral without the consent of Citi Europe provided certain conditions are satisfied, (iii) provide Citi Europe, subject to the provisions set forth in the amended and restated account control agreement, dated December 18, 2014 (the “Control Agreement”), among Aspen Bermuda, Citi Europe and BNY Mellon, with the right and power to exercise exclusive control over the accounts set forth in the Control Agreement and (iv) provide a schedule of currency margins such that if the collateral is denominated in a currency other than the credit currency the collateral shall be reduced by a specified percentage.

On December 12, 2014, Aspen Holdings and certain of its subsidiaries (the “Borrowers”) entered into a first amendment to an amended and restated credit agreement, dated June 12, 2013, with various lenders and Barclays Bank Plc, as administrative agent (“Barclays”). Aspen Holdings has recently established, and may establish additional, special purpose entities that have issued or will issue insurance-linked securities to third-party investors (each, an “ILS Entity” and collectively, the “ILS Entities”). Accordingly, the amended and restated credit agreement was amended, among other things, to (i) exclude ILS Entities from the definition of “Subsidiary”, (ii) permit the Borrowers to invest in ILS Entities and (iii) permit the Borrowers to engage in transactions with an ILS Entity.

Aspen U.K. and Aspen Bermuda have a $100.0 million secured letter of credit facility agreement with Barclays. All letters of credit issued under the facility are used to support reinsurance obligations of the parties to the agreement and their respective subsidiaries. The Company did not extend the maturity date of the Barclays secured letter of credit facility and, as a result, it expired on January 31, 2015 and no new letters of credit can be issued under this facility. As at March 31, 2015, the Company had no outstanding collateralized letters of credit under this facility (December 31, 2014 — $5.0 million).

For further information relating to the Company’s credit facilities, refer to Note 23 of the “Notes to Audited Consolidated Financial Statements” in the Company’s 2014 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

Interest Rate Swaps. As at March 31, 2015, cash collateral with a fair value of $19.5 million was held by the Company’s counterparties to support the current valuation of the interest rate swaps (December 31, 2014 — $22.3 million).

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, notably 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, 2015, 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.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is a discussion and analysis of our financial condition and results of operations for the three months ended March 31, 2015 and 2014. This discussion and analysis should be read in conjunction with the unaudited condensed consolidated financial statements and related notes contained in this report and the audited consolidated financial statements and related notes for the fiscal year ended December 31, 2014, as well as the discussions of critical accounting policies, contained in our Audited Consolidated Financial Statements in our 2014 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

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 2014 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 subsidiaries in Bermuda, the U.K. and the U.S.

Some of the key results for the three months ended March 31, 2015 were:

•

Gross written premiums of $919.2 million for the first quarter of 2015, an increase of 7.4% from the first quarter of 2014. Gross written premiums in reinsurance increased by 2.7% as a result of growth across our other property lines and specialty lines, while gross written premiums in insurance increased by 13.3% as a result of the continued strategic growth of our U.S. and international insurance teams;


•	Net favorable development on prior year loss reserves of $27.5 million for the first quarter of 2015 compared with $28.2 million in the first quarter of 2014, which had a 4.6 percentage point impact on the combined ratio in the first quarter of 2015 and a 5.0 percentage point impact on the combined ratio in the first quarter of 2014;

•

Combined ratio of 88.9% for the first quarter of 2015 compared with a combined ratio of 87.6% for the first quarter of 2014. There were $13.5 million, or 2.3 combined ratio points, of pre-tax catastrophe losses net of reinsurance recoveries in the first quarter of 2015 compared with $10.6 million, or 1.9 percentage points, of pre-tax catastrophe losses net of reinsurance recoveries in the first quarter of 2014;


•	Realized and unrealized foreign exchange losses of $6.4 million for the first quarter of 2015 compared with gains of $0.1 million in the first quarter of 2014 predominantly due to the continued strengthening of the U.S. Dollar during the first quarter of 2015;

•

Realized and unrealized investment gains of $42.9 million for the first quarter of 2015 compared with gains of $13.6 million in the first quarter of 2014. As a result of rebalancing equity investments across subsidiary company balance sheets, a portion of equities were sold that were classified as available for sale, with a commensurate purchase of equities designated as trading securities. As a result of this, there was a net realized investment gain of $28.9 million from this sale.


•	Diluted net income per share of $1.87 for the quarter ended March 31, 2015 compared with diluted net income per share of $1.66⁽¹⁾ in the same quarter last year;


•	Annualized net income return on average equity of 16.4% for the first quarter of 2015 compared with 16.0% for the first quarter of 2014; and


•	Diluted book value per share ⁽¹⁾ of $46.02 as at March 31, 2015, up 2.0% from December 31, 2014, which included net unrealized losses on foreign currency translation, net of taxes, of $26.1 million.

We continue to execute on our strategies to expand our Aspen Capital Markets division as well as our other lines of business within reinsurance while continuing to grow our insurance segment both in the United States and internationally. In ‎our reinsurance segment, we have also successfully increased premiums significantly in specialty reinsurance which has a diverse set of products with some further increases in other property. In the insurance segment, we increased gross written premiums by 13.3%, from $383.3 million in the first three months of 2014 to $434.4 million in the first three months of 2015. As discussed further below, the most meaningful increases were in property and casualty and financial and professional lines.

Total shareholders’ equity increased by $46.5 million to $3,465.8 million for the three months ended March 31, 2015. The most significant movements were:


•	a $106.1 million increase in retained earnings for the period;


•	the repurchase of 787,138 million ordinary shares for $36.5 million through open market repurchases; and


•	net unrealized losses on foreign currency translation, net of taxes, of $26.1 million.


⁽¹⁾	Diluted book value per ordinary share is based on total shareholders’ equity less preference shares (liquidation preference less issue expenses) and non-controlling interest, divided by the total number of issued and potentially dilutive ordinary shares at the end of the period.

Ordinary shareholders’ equity as at March 31, 2015 and December 31, 2014 was:



	As at March 31, 2015			As at December 31, 2014
	($ in millions, except for share amounts)

Outlook and Trends

Overall, the market has continued to experience pressure on rates in reinsurance and insurance. In reinsurance, overall rates decreased by approximately 5% in the first quarter of 2015. Although the property catastrophe market remains under pressure, with rates decreasing approximately 11%, we managed our exposures by redeploying capital to other lines of business where rates are less pressured and by utilizing our Aspen Capital Markets division. In specialty reinsurance, rates are less pressured in certain products which has contributed to the 21% increase in gross written premium in the quarter. Our other property line's gross written premium has also grown by 7% as we are reaching markets where there are not as many competitors with a presence on the ground and we are bringing clients in these markets our suite of product offerings. In line with our reinsurance strategy, we continue to leverage our regional offices around the world. In the first quarter of 2015, our gross written premium increased by 25% in Asia Pacific, Latin America, Middle East and North Africa and we expect that growth to continue.

In insurance, overall rates decreased by 1% in the first quarter of 2015. Certain lines of business, such as programs, U.S. excess casualty and professional and technology risks, experienced rate increases of approximately 5%. With the exception of offshore energy property insurance in the Gulf of Mexico, which behaves similarly to property catastrophe reinsurance, the biggest price reduction we experienced was approximately 6% in U.S. Property. In our U.S. specialty insurance business, we experienced attractive growth rates in surety, professional liability and environmental liability. As a result, we continue to allocate our capital to areas where pricing is holding steady or increasing. In addition, our Lloyd’s business, which is a meaningful part of international insurance, has grown by a compound rate of 16% over the last five years and we expect attractive returns from this business in 2015. In particular, we expect the Lloyd’s global brand and licenses will help position us for the next phase of growth in Asia Pacific and Latin America.

See “Cautionary Statement Regarding Forward-Looking Statements” included in this report.

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 2014 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.

Results of Operations for the Three Months Ended March 31, 2015 Compared to the Three Months Ended March 31, 2014

The following is a discussion and analysis of our consolidated results of operations for the three months ended March 31, 2015 and 2014, 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 $63.7 million, or 7.4%, in the first quarter of 2015 compared to the first quarter of 2014. Premiums from our reinsurance segment increased by 2.7% due to growth across three of our four lines of business, in particular our specialty line with a growth of 21.3% and our other property lines with a growth of 7.3%. Growth in other property lines has been in our pro-rata lines while the increase in specialty reinsurance premiums was due to growth in our specialty marine and agriculture lines. Our insurance segment’s premiums increased by 13.3% principally due to continued growth across our lines in the U.S. in addition to growth in our international financial and professional lines and our U.K. commercial property and casualty lines. The table below shows our gross written premiums for each segment for the three months ended March 31, 2015 and 2014, and the percentage change in gross written premiums for each segment:



Business Segment	Three Months Ended March 31, 2015		Three Months Ended March 31, 2014		% increase
	($ in millions)		($ in millions)
Reinsurance	$	484.8	$	472.2	2.7	%
Insurance	434.4		383.3		13.3	%
Total	$	919.2	$	855.5	7.4	%

Ceded reinsurance. Total reinsurance ceded for the quarter of $156.0 million reduced by $2.0 million from the first quarter of 2014 mainly as a result of our strategy to retain more risk which has reduced the ceded reinsurance costs for our insurance segment. Our retention ratio, defined as net written premium as a percentage of gross written premium, increased by 1.5 percentage points in the first quarter of 2015 from 81.5% to 83.0%. The impact from this strategy has been partially offset through the growth of Aspen Capital Markets which has allowed us to increase our gross catastrophe reinsurance line sizes resulting in more risk ceded to third-party investors in our reinsurance segment.

Net premiums earned. Net premiums earned in the first quarter of 2015 increased by 4.8% from the first quarter of 2014, broadly consistent with the increase in gross written premiums in the period.

Losses and loss adjustment expenses. The loss ratio for the quarter of 51.6% increased by 0.7 percentage points compared to the first quarter of 2014 due to increased current year losses. There were $13.5 million, or 2.3 combined ratio points, of pre-tax catastrophe losses net of reinsurance recoveries in the first quarter of 2015 compared with $10.6 million, or 1.9 percentage points, of pre-tax catastrophe losses net of reinsurance recoveries in the first quarter of 2014. In addition to weather-related events, we incurred a $6.8 million loss associated with an airline crash and a $7.5 million loss in connection with a floating gas production and storage facility. There were no significant large losses reported in the first quarter of 2014.

In the reinsurance segment, the 0.9 percentage point increase in the loss ratio from 41.4% in the first quarter of 2014 to 42.3% in the first quarter of 2015 was due to higher catastrophe losses and a reduction in prior year reserve releases offset by lower attritional losses. In the first quarter of 2014, we reported $5.5 million of catastrophe losses associated with U.S. and Japanese storms while in the current quarter we recognized $7.7 million of catastrophe losses associated with European, U.S. and Australian storms. Reserve releases reduced from $21.2 million in the first quarter of 2014 to $13.2 million in the current period.

In the insurance segment, the loss ratio for the first quarter of 2015 reduced by 1.0 percentage point from 59.3% in the first quarter of 2014 to 58.3% in the first quarter of 2015 due to an increase in prior year reserve releases and lower underlying attritional losses offset by two medium-sized headline losses. Catastrophe losses increased marginally from $5.1 million in the first quarter of 2014 to $5.8 million in the first quarter of 2015. In the first quarter of 2015, we incurred a $5.8 million loss following an airliner crash and a $7.5 million loss in connection with a floating gas production and storage facility. In the first quarter of 2014, there were no significant large losses reported. Reserve releases were $14.3 million for the first quarter of 2015 compared to $7.0 million for the comparative quarter last year.

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, 2015 and 2014 were as follows:



Business Segment	Three Months Ended March 31, 2015		Three Months Ended March 31, 2014
Reinsurance	42.3	%	41.4	%
Insurance	58.3	%	59.3	%
Total Loss Ratio	51.6	%	50.9	%

We also present, in the tables below, loss ratios 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 first quarter 2015 catastrophe losses as losses associated with storms in Europe, Australia and North America. Catastrophe losses in the first quarter of 2014 related to winter storms in the U.S. and Japan and flood losses in the U.K.

The underlying changes in loss ratios by segment are shown in the tables below for the three months ended March 31, 2015 and 2014. The total loss ratio represents the calendar year U.S. GAAP loss ratio. The current year adjustments represent the effect on the loss ratio of net claims and reinstatement premiums, if any, from catastrophe loss events.



For the Three Months Ended March 31, 2015	Total Loss Ratio		Current Year Adjustments		Loss Ratio Excluding Current Year Adjustments
Reinsurance	42.3	%	(3.1	)%	39.2	%
Insurance	58.3	%	(1.7	)%	56.6	%
Total	51.6	%	(2.3	)%	49.3	%



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	%

Reserve releases in our reinsurance segment reduced from $21.2 million in the first quarter of 2014 to $13.2 million in the current period. Favorable reserve development in the first quarter 2015 was across all reinsurance lines with the most significant release in specialty, in particular aviation and marine lines. The lower level of reserve releases this quarter compared to 2014 in reinsurance is attributable mainly to specialty reinsurance. The insurance segment had a $14.3 million reserve release this quarter compared to $7.0 million in the comparative quarter in 2014 due primarily to favorable development in property and casualty lines.

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 expenses. 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, 2015 and 2014:



	Three Months Ended March 31, 2015						Three Months Ended March 31, 2014
Ratios Based on Gross Earned Premium	Reinsurance		Insurance		Total		Reinsurance		Insurance		Total
Policy acquisition expense ratio	20.1	%	15.9	%	17.5	%	18.1	%	16.5	%	17.2	%
General and administrative expense ratio⁽¹⁾	12.2		13.3		15.0		11.8		12.3		14.7
Gross expense ratio	32.3		29.2		32.5		29.9		28.8		31.9
Effect of reinsurance	2.1		6.0		4.8		1.3		7.0		4.8
Total net expense ratio	34.4	%	35.2	%	37.3	%	31.2	%	35.8	%	36.7	%


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

Policy acquisition expenses in the reinsurance segment increased compared to the first quarter of 2014 due to the current quarter being impacted by a number of commutation adjustments which reduced earned premiums without any equivalent reduction in commissions payable, as well as a $1.7 million profit commission adjustment. The reduction in the acquisition ratio in the insurance segment is principally due to increases in commissions payable to us on ceded reinsurance cessions.

General, administrative and corporate expenses increased by $6.6 million to $102.2 million from $95.6 million in the first quarter of 2014. The general, administrative and corporate expense ratio increased by 0.3 percentage points due to a fair value adjustment on equity compensation as well as expenses related to the recruitment of senior underwriters in our insurance segment. Corporate expenses in the first quarter of 2014 included $3.0 million in non-recurring costs associated with the cost of defending the unsolicited approach from Endurance Specialty Holdings Ltd. (“Endurance”).

Net investment income. Net investment income for the quarter of $47.4 million decreased by 4.2% compared to $49.5 million in the first quarter of 2014 due primarily to a reduction in income from our fixed income securities.

Change in fair value of derivatives. In the three months ended March 31, 2015, we recorded a loss of $3.2 million (2014 — loss of $1.9 million) in respect of interest rate swaps and a loss of $4.6 million (2014 — gain of $3.0 million) in respect of foreign exchange contracts.

Income before tax. In the first quarter of 2015, income before tax was $133.1 million (2014 — $124.2 million) comprising the amounts set out in the table below:



	Three Months Ended March 31, 2015			Three Months Ended March 31, 2014
	($ in millions)
Underwriting income	$	80.5		$	87.7
Corporate expenses	(14.5		)	(16.9		)
Other income	1.3			(0.1		)
Net investment income	47.4			49.5
Change in fair value of derivatives	(7.8		)	1.1

Net realized and unrealized foreign exchange (losses)/gains	(6.4		)	0.1
Interest expense	(7.4		)	(7.4		)
Income before tax	$	133.1		$	124.2

Taxes. Income tax expense for the three months ended March 31, 2015 was $5.1 million (2014 — $3.8 million) equating to an estimated effective tax rate of 3.8% (2014 — 3.1%). The effective tax rate represents an estimate of the tax rate which will apply to our pre-tax income for 2015 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 decreased from 23% to 21%, effective April 1, 2014, with a further reduction to 20% from April 1, 2015) and the U.S. (where the

corporate tax rate is 34%). However, at December 31, 2014, the Company had net operating losses carried forward for U.S. Federal income tax purposes of $267.4 million which are available to offset future U.S. Federal taxable income, if any, with expiry periods between 2026 and 2034. The increase in tax rate for the quarter is due predominantly to a greater proportion of our profits derived from our U.K.-based operations relative to Bermuda.

Net income after tax. Net income after tax for the three months ended March 31, 2015 was $128.0 million, equivalent to basic earnings per ordinary share of $1.91 adjusted for the $9.5 million preference share dividends. Fully diluted earnings per ordinary share were $1.87. Net income after tax for the three months ended March 31, 2014 was $120.4 million, equivalent to basic earnings per ordinary share of $1.70 after deducting $9.5 million in preference share dividends. Fully diluted earnings per ordinary share were $1.66 for the three months ended March 31, 2014.

Investment gains/(losses). Total realized and unrealized investment gains for the three months ended March 31, 2015 were $42.9 million (2014 — $13.6 million) comprising the amounts set out in the table below:

As a result of rebalancing equity investments across subsidiary company balance sheets, a portion of equities were sold that were classified as available for sale, with a commensurate purchase of equities designated as trading securities. As a result of this, there was a net realized investment gain of $28.9 million on this sale.

Other comprehensive income (loss). Total other comprehensive income reduced by $31.3 million (2014 — gain of $15.5 million), net of taxes, for the three months ended March 31, 2015. This was comprised of a $29.1 million gain in the net unrealized available for sale investment portfolio (2014 — $20.5 million net unrealized gain), a $31.9 million reclassification of net realized gains to net income (2014 — $0.2 million reclassified net realized gains) as a result of the sale of the available for sale equity portfolio, net unrealized losses in foreign currency translation of $26.1 million (2014 — $4.8 million net unrealized losses) mainly as a result of the strengthening of the U.S. dollar in the period and a $2.4 million unrealized loss (2014 — $Nil) on hedged foreign exchange contracts.

Dividends. The dividend on our ordinary shares increased from $0.20 per ordinary share to $0.21 per ordinary share on April 22, 2015. The dividend on our ordinary shares increased from $0.18 per ordinary share to $0.20 per ordinary share on April 23, 2014. Dividends paid on our ordinary and preference shares in the three months ended March 31, 2015 were $12.4 million (2014 — $11.7 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.

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, 2015 and 2014. The contributions of each segment to gross written premiums in the three months ended March 31, 2015 and 2014 were as follows:



	Gross Written Premiums
Business Segment	Three Months Ended March 31, 2015		Three Months Ended March 31, 2014

Reinsurance	52.7	%	55.2	%

	($ in millions)
Reinsurance	$	484.8	$	472.2
Insurance	434.4		383.3
Total	$	919.2	$	855.5

Reinsurance

Our reinsurance segment consists of property catastrophe reinsurance, other property reinsurance (risk excess, pro rata and facultative), casualty reinsurance (U.S. treaty, international treaty and global facultative) and specialty reinsurance (credit and surety, agriculture, marine, aviation, engineering and other specialty). For a more detailed description of this segment, see Part I, Item 1, “Business — Business Segments — Reinsurance” in the Company’s 2014 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

Gross written premiums. Gross written premiums in our reinsurance segment increased by 2.7% compared to the three months ended March 31, 2014. The table below shows our gross written premiums for each line of business for the three months ended March 31, 2015 and 2014, and the percentage change in gross written premiums for each such line:



Lines of Business	Three Months Ended March 31, 2015		Three Months Ended March 31, 2014		% increase/(decrease)
	($ in millions)		($ in millions)
Property catastrophe reinsurance	$	153.8	$	168.8	(8.9	)%
Other property reinsurance	109.9		102.4		7.3	%
Casualty reinsurance	114.7		113.3		1.2	%
Specialty reinsurance	106.4		87.7		21.3	%
Total	$	484.8	$	472.2	2.7	%

The reduction in property catastrophe premiums in the first quarter of 2015 is mainly due to planned reductions associated with more challenging market conditions. The increase in other property reinsurance is due to increases in our pro rata lines while gross written premiums in specialty reinsurance increased due to a growth in specialty marine and agriculture lines.

Losses and loss adjustment expenses. The loss ratio for the three months ended March 31, 2015 was 42.3% compared to 41.4% in the equivalent period in 2014. The increase in the loss ratio is primarily attributable to a reduction in prior year reserve releases and higher catastrophe losses having a more significant impact on the loss ratio than the lower attritional losses in the quarter. In the first quarter of 2015, we experienced $7.7 million of natural catastrophe losses, consisting of $3.6 million of losses associated with European storms and $4.1 million of losses from other weather-related events in North America and Australia. The comparable quarter of 2014 experienced $5.5 million of catastrophe losses associated with U.S. and Japanese storms. There was an $8.0 million decrease in prior year reserve releases from $21.2 million in the first quarter of 2014 to $13.2 million in the current period mainly due to reduced reserve releases from specialty reinsurance. Reserve releases for the current and comparative quarters were mainly as a result of favorable development in the specialty, casualty and property catastrophe 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 was $53.4 million for the three months ended March 31, 2015 equivalent to 21.4% of net premiums earned (2014 — $50.4 million or

18.9% of net premiums earned). The acquisition expense ratio in the current quarter was adversely affected by commutation adjustments in our specialty lines which reduced net earned premium without any equivalent reduction in commissions as well as a $1.7 million profit commission adjustment. The general and administrative expenses were generally flat in the quarter at $32.4 million (2014 — $32.8 million). However, the general and administrative expense ratio increased to 13.0% from 12.3% for the same period in 2014 due to the impact of commutations on net earned premiums.

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 2014 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 13.3% compared to the three months ended March 31, 2014. The table below shows our gross written premiums for each line of business for the three months ended March 31, 2015 and 2014, and the percentage change in gross written premiums for each line:



Lines of Business	Three Months Ended March 31, 2015		Three Months Ended March 31, 2014		% increase
	($ in millions)		($ in millions)
Property and casualty insurance	$	213.4	$	176.3	21.0	%
Marine, aviation and energy insurance	131.7		131.7		—	%
Financial and professional lines insurance	89.3		75.3		18.6	%
Total	$	434.4	$	383.3	13.3	%

Notable areas of gross written premiums growth include U.K. property and liability packages, political risks and environmental liability.

Losses and loss adjustment expenses. The loss ratio for the quarter was 58.3% compared to 59.3% for the three months ended March 31, 2014, with the reduction in the loss ratio due to an increase in prior year reserves releases offset by a $5.8 million aviation loss and a $7.5 million loss in connection with a floating gas production and storage facility and a small increase in catastrophe losses. There was a $7.3 million increase in prior year reserve releases from $7.0 million in the first quarter of 2014 to $14.3 million in the current period. The loss ratio for the current quarter has also been adversely affected by $5.8 million of catastrophe losses associated with U.S. weather-related events while the comparative period in 2014 experienced $5.1 million of U.S. and U.K. storm losses.

The reserve releases in the current quarter were predominantly from our property and casualty lines. The reserve releases in the comparative quarter in 2014 were mainly attributable to shorter-tail business lines, principally our U.S. and U.K. property, U.S. energy and inland marine 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 for the three months ended March 31, 2015 decreased to 19.1% of net premiums earned compared to 20.5% in the first quarter of 2014 as a result of changes in business mix and increased commissions payable to us on ceded reinsurance cessions. Our general and administrative expenses increased by $9.4 million to $55.3 million for the three months ended March 31, 2015 from $45.9 million in the first quarter of 2014 due to a fair value adjustment on equity compensation as well as expenses related to the recruitment of senior underwriters. The expense ratio reduced by 0.6 percentage points overall.

Cash and investments

As at March 31, 2015 and December 31, 2014, total cash and investments were $8.5 billion and $8.6 billion, respectively. The composition of our investment portfolio is summarized below:

Fixed Income Securities. As at March 31, 2015, the average credit quality of our fixed income portfolio was “AA-,” with 88.2% of the portfolio rated “A” or higher. As at December 31, 2014, the average credit quality of our fixed income portfolio was “AA-,” with 88.3% of the portfolio rated “A” or higher. Where the credit ratings were split between the two main rating agencies, S&P and Moody’s, the lowest rating was used. Our fixed income portfolio duration as at March 31, 2015 was 3.45 years compared to 3.50 years as at December 31, 2014 excluding the impact of the interest rate swaps, and 3.27 years including the impact of interest rate swaps (December 31, 2014 — 3.29 years).

Our mortgage-backed portfolio is supported by loans diversified across a number of geographic and economic sectors.

Equity Securities. Equity securities are comprised of U.S. and foreign equity securities and in prior periods were classified as available for sale or trading. As a result of rebalancing equity investments across subsidiary company balance sheets, a portion of equities were sold that were classified as available for sale, with a commensurate purchase of equities designated as trading securities. As a result, there was a realized investment gain of $28.9 million on this sale. The total investment return from the available for sale and trading equity portfolios for the three months ended March 31, 2015 and 2014 was as follows:

Interest rate swaps. In 2014 we decided to let our interest rate swap program roll-off and not renew maturing positions. This decision was made after an extensive reassessment of the costs of maintaining an interest rate swap program in a steep yield curve environment. In addition, the continued uncertainty in the global economy, weak oil prices and low inflation make it difficult to gauge the timing and speed of interest rate rises by the Federal Reserve. As at March 31, 2015, our interest rate swaps program was a notional $951.3 million consistent with the $951.3 million at December 31, 2014, and during the three months ended March 31, 2015, no swaps rolled off. Our interest rate swaps program continues to partially mitigate the negative impact of rising interest rates on the market value of our fixed income portfolio. For the three months ended March 31, 2015, there was a charge in respect of the interest rate swaps of $3.2 million which consisted of a $2.9 million mark to market gain less $6.1 million of net interest payments. As at March 31, 2015, our interest rate swap position reduced the duration of the fixed-income portfolio from 3.45 years to 3.27 years and the duration of the aggregate portfolio from 2.81 years to 2.66 years.

European Fixed Income and Equity Exposures. As at March 31, 2015, we had $1,038.3 million, or 12.2% of our total cash and investments, invested in securities issued by 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 corporate bonds.

We manage our European fixed income exposures by proactively adapting our investment guidelines to our views on the European debt crisis. We continue to prohibit purchases of GIIPS sovereign (including Belgium) and guaranteed debt, peripheral European bank debt and corporate bonds issued by companies domiciled in GIIPS countries.

In May 2014, we amended our restrictions on purchases of bonds issued by U.K and non-peripheral European corporate financial issuers to allow the purchase of those issued by select issuers.

The tables below summarize our European holdings by country (Eurozone and non-Eurozone), rating and sector as at March 31, 2015. Equity investments included in the table below are not rated (“NR”). Where the credit ratings were split between the two main rating agencies, S&P and Moody’s, the lowest rating was used.

Reserves for Losses and Loss Adjustment Expenses

As at March 31, 2015, we had total net loss and loss adjustment expense reserves of $4,338.8 million (December 31, 2014 — $4,400.8 million). This amount represented our selected reserves for 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, 2015 and December 31, 2014, respectively:



	As at March 31, 2015
Business Segment	Gross		Reinsurance Recoverable			Net
	($ in millions)
Reinsurance	$	2,447.3	$	(36.4	)	$	2,410.9
Insurance	2,251.6		(323.7		)	1,927.9
Total losses and loss expense reserves	$	4,698.9	$	(360.1	)	$	4,338.8



	As at December 31, 2014
Business Segment	Gross		Reinsurance Recoverable			Net

Total losses and loss expense reserves	$	4,750.8	$	(350.0	)	$	4,400.8

For the three months ended March 31, 2015, there was a reduction of our estimate of the ultimate net claims to be paid in respect of prior accident years of $27.5 million. An analysis of this reduction by business segment is as follows for each of the three months ended March 31, 2015 and 2014:



	For the Three Months Ended
Business Segment	March 31, 2015		March 31, 2014
	($ in millions)
Reinsurance	$	13.2	$	21.2
Insurance	14.3		7.0
Total losses and loss expense reserves reductions	$	27.5	$	28.2

The key elements which gave rise to the net positive development during the three months ended March 31, 2015 were as follows:

Reinsurance. Net reserve releases were $13.2 million in the current quarter. The largest releases in the quarter were $6.0 million from specialty lines due to a reduction in reserves for aviation and marine lines, a $3.2 million reduction in reserves for casualty lines following better than expected development and a $2.9 million reduction in reserves for property catastrophe due to better than expected development.

Insurance. Net reserve releases of $14.3 million in the current quarter were attributable to the majority of our business lines with the largest release of $12.5 million from our property and casualty business lines.

For a more detailed description see Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Reserves for Losses and Loss Adjustment Expenses,” included in our 2014 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

Capital Management

The following table shows our capital structure as at March 31, 2015 compared to December 31, 2014:



	As at March 31, 2015		As at December 31, 2014
	($ in millions)
Share capital, additional paid-in capital, retained income and accumulated other comprehensive income attributable to ordinary shareholders	$	2,910.0	$	2,863.5
Preference shares (liquidation preferences net of issue costs)	555.8		555.8
Long-term debt	549.1		549.1
Loan notes issued by variable interest entities⁽¹⁾	76.7		138.6
Total capital	$	4,091.6	$	4,107.0

(1) We do not consider the loan notes issued by VIEs to be part of our permanent capital as the noteholders have no recourse to the other assets of the Company.

As at March 31, 2015, total shareholders’ equity was $3,465.8 million compared to $3,419.3 million as at December 31, 2014. Our total shareholders’ equity as at March 31, 2015 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, 2014 — $555.8 million).

On April 22, 2015, we announced a 5% increase in our quarterly dividend to our ordinary shareholders from $0.20 per ordinary share to $0.21 per ordinary share. On April 23, 2014, we announced an 11.1% increase in our normal quarterly dividend to our ordinary shareholders from $0.18 per share to $0.20 per ordinary share.

We acquired and cancelled 787,138 ordinary shares in the three months ended March 31, 2015. The total consideration paid was $36.5 million, with the average price for the three months ended March 31, 2015 being $46.32. As at March 31, 2015, we had $463.5 million remaining under our current share repurchase authorization of $500.0 million granted on February 5, 2015.

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 28.9% as at March 31, 2015 (December 31, 2014 — 30.8%).

Our senior notes were the only material debt issued by Aspen Holdings as of March 31, 2015, less amortization of expenses was $549.1 million (December 31, 2014 — $549.1 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, 2015, this ratio was 11.5% (December 31, 2014 — 17.0%).

In addition to the senior notes issued by Aspen Holdings, we have also reported $76.7 million of debt issued by Silverton (December 31, 2014 — $138.6 million). For further information relating to Silverton, refer to Note 7 of the “Notes to the Audited Consolidated Financial Statements” in the Company’s 2014 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

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 $3,465.8 million as at March 31, 2015 (December 31, 2014 — $3,419.3 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, 2015, Aspen Holdings held $111.7 million of cash and cash equivalents (December 31, 2014 — $86.8 million) with the increase due to the receipt of dividend income from subsidiary companies less a total of $36.5 million of ordinary share repurchases in the three months ended March 31, 2015. 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, 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 “Letter of Credit Facilities” 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 2014 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 16 of the “Notes to the Audited Consolidated Financial Statements” in our 2014 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

Operating Subsidiaries. As at March 31, 2015, the Operating Subsidiaries held $1,062.1 million (December 31, 2014 — $1,296.2 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 the 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, 2015 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, 2015 and December 31, 2014:

Consolidated Cash Flows for the Three Months Ended March 31, 2015. Total net cash flow from operations for the three months ended March 31, 2015 was $72.0 million, a decrease of $139.9 million from the comparative period in 2014. The decrease is mainly attributable to an increase in claim payments made in the first three months of 2015 in respect of 2014 losses compared to claim payments made in the first three months of 2014 in respect of 2013 losses. For the three months ended March 31, 2015, our cash flow from operations provided us with sufficient liquidity to meet our operating requirements.

Letter of Credit Facilities. 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 (“Barclays”), which amends and restates the credit agreement dated as of July 30, 2010 among Aspen Holdings, the Borrowers, various lenders and Barclays. The credit facility will be used primarily for letters of credit in connection with our insurance and reinsurance businesses to finance our working capital needs and those of our subsidiaries 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, 2015, 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.

On December 12, 2014, Aspen Holdings and the Borrowers entered into a first amendment to the Credit Agreement with various lenders and Barclays, which amends the Credit Agreement. Aspen Holdings has recently established, and may establish additional, special purpose entities that have issued or will issue insurance-linked securities to third-party investors (each, an “ILS Entity” and collectively, the “ILS Entities”). Accordingly, the Credit Agreement was amended, among other things, to (i) exclude ILS Entities from the definition of “Subsidiary”, (ii) permit the Borrowers to invest in ILS Entities and (iii) permit the Borrowers to engage in transactions with an ILS Entity.

On June 30, 2014, Aspen Bermuda and Citi Europe replaced an existing letter of credit facility, dated July 30, 2012, in a maximum aggregate amount of up to $950.0 million (the “LOC Facility”) comprised of two maturity tranches (Tranche I with a limit of $650.0 million and Tranche II with a limit of $300.0 million) which expired on its own terms on June 30, 2014. The LOC Facility was replaced with a new letter of credit facility in a maximum aggregate amount of up to $575.0 million (the “New LOC Facility”). Under the New LOC Facility, which will expire on June 30, 2016, Aspen Bermuda will pay to Citi Europe (a) a letter of credit fee based on the available amounts of each letter of credit and (b) a commitment fee, which varies based upon usage, on the unutilized portion of the New LOC Facility. Aspen Bermuda will also pay interest on the amount drawn by any beneficiary under the New LOC Facility at a rate per annum of LIBOR plus 1% (plus reserve asset costs, if any) from the date of drawing until the date of reimbursement by Aspen Bermuda. The New LOC Facility is used to secure obligations of Aspen Bermuda to its policyholders. In addition to the New LOC Facility, we also use regulatory trusts to secure our obligations to policyholders.

The terms of a pledge agreement between Aspen Bermuda and Citi Europe (pursuant to an Assignment Agreement dated October 11, 2006) dated January 17, 2006, as amended, were also amended on June 30, 2014 to change the types of securities or other assets that are acceptable as collateral under the New LOC Facility. All other agreements relating to Aspen Bermuda’s LOC Facility, which now apply to the New LOC Facility with Citi Europe, as previously filed with the United States Securities and Exchange Commission, remain in full force and effect. As at March 31, 2015, we had $463.5 million of outstanding collateralized letters of credit under the New LOC Facility (December 31, 2014 — $463.6 million under the LOC Facility).

On December 18, 2014, Aspen Bermuda and Citi Europe entered into an amended and restated pledge agreement (“pledge agreement”) to, among other things, (i) change the types of securities or other assets that qualify as collateral pledged under the pledge agreement, (ii) provide Aspen Bermuda the right to give certain directions or entitlement orders to The Bank of New York Mellon (“BNY Mellon”), as securities intermediary, relating to the collateral without the consent of Citi Europe provided certain conditions are satisfied, (iii) provide Citi Europe, subject to the provisions set forth in the amended and

restated account control agreement, dated December 18, 2014 (the “control agreement”), among Aspen Bermuda, Citi Europe and BNY Mellon, with the right and power to exercise exclusive control over the accounts set forth in the control agreement and (iv) provide a schedule of currency margins such that if the collateral is denominated in a currency other than the credit currency the collateral shall be reduced by a specified percentage.

In addition, 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, 2015, we had $Nil of outstanding collateralized letters of credit under this facility (December 31, 2014 — $5.0 million). The Company did not renew this secured letter of credit facility which expired on January 31, 2015 and no new letters of credit can be issued under this facility.

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 at March 31, 2015:



	2015		2016		2017		2018		2019		Later Years		Total
	($ in millions)
Operating Lease Obligations	$	10.1	$	9.8	$	8.5	$	7.0	$	6.1	$	1.5	$	43.0
Long-Term Debt Obligations⁽¹⁾	—		—		—		—		—		550.0		550.0
Reserves for losses and LAE⁽²⁾	1,130.1		927.6		663.5		479.3		351.2		1,147.2		4,698.9
Total	$	1,140.2	$	937.4	$	672.0	$	486.3	$	357.3	$	1,698.7	$	5,291.9


⁽¹⁾	The long-term debt obligations disclosed above do not include the $32.3 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 $76.7 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 the Company’s 2014 Annual Report on Form 10-K under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies — Reserves for Losses and Loss Expenses” filed with the United States Securities and Exchange Commission.

Further information on operating leases is given in Item 2, “Properties” in our 2014 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission.

For a discussion of derivative instruments we have entered into, please see Note 10 to our unaudited condensed consolidated financial statements for the three months ended March 31, 2015 included in this report.

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 at March 31, 2015, 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 report 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,” “assume,” “objective,” “target,” “could,” “would,” “should,” “plan,” “estimate,” “project,” “outlook,” “trends,” “future,” “seek,” “will,” “may,” “aim,” “likely,” “continue,” “intend,” “guidance,” “on track,” 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 2014 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 our control that could cause actual results to differ materially from such statements.

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:


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


•	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;


•	the assumptions and uncertainties underlying reserve levels that may be impacted by future payments for settlements of claims and expenses or by other factors causing adverse or favorable development, including our assumptions on inflation costs associated with long-tail casualty business which could differ materially from actual experience;


•	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;


•	the models we use to assess our exposure to losses from future natural catastrophes contain inherent uncertainties and our actual losses may differ significantly from expectations;


•	our capital models may provide materially different indications than actual results;


•	increased competition from existing insurers and reinsurers and from alternative capital providers and insurance-linked funds and collateralized special purpose insurers 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;


•	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 acquisition strategy;


•	the recent consolidation in the (re)insurance industry;


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


•	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 results;


•	changes in general economic conditions, including inflation, deflation, 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;


•	the risks associated with the management of capital on behalf of investors;


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


•	our ability to adequately model and price the effects of climate cycles and climate change;


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


•	the risks related to litigation;


•	the effectiveness of our risk management loss limitation methods, including our reinsurance purchasing;


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

•

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 2015 and prior years 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 and deterioration in loss estimates;


•	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;


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


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


•	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 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 crisis;


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


•	changes in accounting principles or policies or in the application of such accounting principles or policies;


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


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

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. All forward-looking statements 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, we partially mitigate our 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, 2015, our fixed income portfolio had an approximate duration of 3.45 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	7,024.4		6,907.3		6,790.1		6,673.0		6,555.9
Gain/(loss) $ in millions	234.3		117.1		—		(117.1	)	(234.3	)
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 $719.0 million as at March 31, 2015, equivalent to 8.5% of the total of investments, cash and cash equivalents at that date (December 31, 2014 — $725.9 million, 8.5%). 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 at March 31, 2015, 81.5% (December 31, 2014 — 79.3%) of our cash, cash equivalents and investments were held in U.S. Dollars, 7.8% (December 31, 2014 — 8.4%) were in British Pounds and 10.7% (December 31, 2014 — 12.3%) were in other currencies. For the three months ended March 31, 2015, 20.8% (December 31, 2014 — 16.5%) 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 2015.

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, 2015 would have impacted our net reportable British Pound net assets by approximately $7 million for the three months ended March 31, 2015 (March 31, 2014 — approximately $5 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. For a discussion of derivative instruments including foreign exchange contracts that we have entered into, please see Note 10 to our unaudited condensed consolidated financial statements for the three months ended March 31, 2015 included in this report.

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, 2015, the average rating of fixed income securities in our investment portfolio was “AA-” (December 31, 2014 — “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, 2015. Based upon that evaluation, the Company’s management is not aware of any change in its internal control over financial reporting that occurred during the three months ended March 31, 2015 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

There have been no significant changes in the Company’s risk factors as discussed in the Company’s Annual

Report on Form 10-K for the year ended December 31, 2014 filed with the United States Securities and Exchange Commission. Please refer to the “Cautionary Statement Regarding Forward-Looking Statements” provided elsewhere in this report.
