THE NAVIGATORS GROUP, INC. AND SUBSIDIARIES

Notes to Interim Consolidated Financial Statements (Unaudited)

Note 1. Organization and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying interim consolidated financial statements are unaudited and reflect all adjustments which, in the opinion of management, are necessary to fairly present the results of The Navigators Group, Inc. and its subsidiaries for the interim periods presented on the basis of United States generally accepted accounting principles (“GAAP” or “U.S. GAAP”). All significant intercompany transactions and balances have been eliminated in consolidation. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported revenues and expenses during the reporting periods. The results of operations for any interim period are not necessarily indicative of results for the full year. The interim consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2014. Certain amounts for the prior year have been reclassified to conform with the current period presentation. Unless the context requires otherwise, the terms “we,” “us,” “our,” or “our Company” are used to mean The Navigators Group, Inc., a Delaware holding company established in 1982, and its subsidiaries. The terms “Parent” or “Parent Company” are used to mean The Navigators Group, Inc. without its subsidiaries.

Organization

We are an international insurance company with a long-standing area of specialization in Marine insurance. Our Property and Casualty (“P&C”) insurance business primarily offers General Liability coverage and Umbrella & Excess Liability coverage to commercial enterprises through our Primary and Excess Casualty divisions. We have also developed niches in Professional Liability insurance, through our Management Liability and Errors and Omissions divisions. Beginning in 2010, we added reinsurance products through our Assumed Reinsurance division.

We operate through various wholly-owned subsidiaries, including Navigators Insurance Company, inclusive of its United Kingdom Branch (“U.K. Branch”), and Navigators Specialty Insurance Company, both of which are U.S. insurance companies, and Navigators Underwriting Agency Ltd., a Lloyd’s of London (“Lloyd’s”) underwriting agency that manages Lloyd’s Syndicate 1221 (“the Syndicate”) in the U.K. The Company controls 100% of the Syndicate’s stamp capacity.

Foreign Exchange Remeasurement and Translation

During the first quarter of 2014, the Syndicate revised its foreign exchange accounting methodology from reporting its financial position and results using three functional currencies (GBP, USD and CAD) to one functional currency (USD). The USD was chosen as the single functional currency as the majority of the Syndicate’s insurance business has been and continues to be transacted in USD. This cumulative change in remeasurement has resulted in an immaterial correction of $10.0 million ($6.6 million after-tax) in Accumulated other comprehensive income (“AOCI”), on the Consolidated Balance Sheets, offset by a gain in Other income in the Consolidated Statements of Income.

Catastrophe Risk Management

We have exposure to losses caused by hurricanes, earthquakes, and other natural and man-made catastrophic events. The frequency and severity of catastrophic events is unpredictable. The extent of covered losses from a catastrophe is a function of both the total amount of insured exposure in an area affected by the event and the severity of the event. We had no material catastrophic events occur in the first quarter 2015.

Income Taxes

The income tax provision has been computed based on our estimated annual effective tax rate. Our effective tax rate for the quarter differs from the federal tax rate of 35% principally because of tax-exempt investment income and dividends received deduction.

Current and Pending Accounting Pronouncements

As of January 1, 2015, we did not adopt any new accounting pronouncements. In April 2015, the Financial Accounting Standards Board issued a new pronouncement, Accounting Standards Update 2015-03 – Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs, which will be effective for fiscal years beginning after December 15, 2015. The new pronouncement was issued to simplify presentation of debt issuance costs. We are assessing the future impact of this update to our Consolidated Financial Statements. There were no additional pending accounting pronouncements that are expected to have a significant impact on the consolidated financial statements upon adoption.

Note 2. Segment Information

During the first quarter of 2015, we realigned our reporting segments from Insurance Companies, Lloyd’s Operations and Corporate to U.S. Insurance, International Insurance (“Int’l Insurance”), Global Reinsurance (“GlobalRe”) and Corporate. The new segment presentation reflects an increase in the level of importance that the Chief Operating Decision Maker now places on the results of the underlying operating segments when aggregated and reported in alignment with the products and services offered to the marketplace versus when aggregated and reported in alignment with our legal entity structure. Over the past few years, we have been monitoring the growth and stability of our reinsurance business and in 2015 determined that reinsurance has become a stable and significant component of our Company. We are also increasing our focus on additional international insurance markets by establishing underwriting offices in Continental Europe. The offices were fully operational during our January renewal season. We considered these changes in conjunction with operating and reportable segments.

Our previously reported segments were consistent with our legal entity structure; however, our new reporting segments are now primarily reflective of where our business is written. We reclassified our international business from our previously reported Lloyd’s Operations segment to the Int’l Insurance segment. We also reclassified our non-Lloyd’s business written internationally (primarily business written by the U.K. Branch) into this segment and have excluded Assumed Reinsurance. Our new GlobalRe segment was previously reported within our U.S. Insurance and Lloyd’s Operations segments as Assumed Reinsurance. Our U.S. Insurance segment now excludes the U.K. Branch and Assumed Reinsurance. Our Corporate segment now includes investment income (loss), interest income (loss), foreign exchange gain (loss) and income tax benefit (expense), which are not allocated to the U.S. Insurance, Int’l Insurance and GlobalRe segments (together “underwriting segments”). We do not allocate assets under the new reporting segments, as it is impracticable to do so.

As noted above, we classify our business into three underwriting segments (U.S. Insurance, Int’l Insurance and GlobalRe) and a Corporate Segment. Both the U.S. Insurance and Int’l Insurance reporting segments are each comprised of three operating segments: Marine, Professional Liability and P&C. These operating segments have been aggregated into the aforementioned reporting segments based upon the criteria specified in Accounting Standards Codification 280, Segment Reporting. Consistent with the guidance, these operating segments; (a) engage in business activities from which they may earn revenues and incur expenses, (b) are regularly reviewed by our management to assess the performance of the segments and make decisions about resources to be allocated to the segments and (c) have discrete financial information.

We evaluate the performance of each of the underwriting segments based on underwriting results. Underwriting results are measured based on underwriting profit or loss and the related combined ratio, which are both non-GAAP measures of underwriting profitability. Underwriting profit or loss is calculated from net earned premiums less the sum of net losses and loss adjustment expenses (“LAE”), commission expenses, other operating expenses, and other underwriting income (expense). The combined ratio is derived by dividing the sum of net loss and LAE, commission expenses, other operating expenses and other underwriting income (expense) by net earned premiums. A combined ratio of less than 100% indicates an underwriting profit and greater than 100% indicates an underwriting loss. Our underwriting performance is evaluated separately from the rest of our operations. The performance of our investment portfolios, our liquidity and capital resource needs, our foreign currency exposure and our tax planning strategies are evaluated on a consolidated basis within our Corporate reporting segment.

The accounting policies used to prepare the segment reporting data for our reporting segments are the same as those described in Note 1 and Note 3 of our Annual Report on Form 10-K for the year ended December 31, 2014. In addition, 2014 data presented in this Quarterly Report has been recast to align with the new segment reporting described above.

As of March 31, 2015 and December 31, 2014, our Company did not have a concentration of greater than 5% of invested assets in a single non-U.S. government-backed issuer.

As of March 31, 2015 and December 31, 2014, fixed maturities for which non-credit OTTI was previously recognized and included in AOCI are now in an unrealized gains position of $0.7 million.

The fair value of our Company’s investment portfolio may fluctuate significantly in response to various factors such as changes in interest rates, investment quality ratings, equity prices, foreign exchange rates and credit spreads. Our Company does not have the intent to sell nor is it more likely than not that it will have to sell fixed maturities in unrealized loss positions that are not other-than-temporarily impaired before recovery. For structured securities, default probability and severity assumptions differ based on property type, vintage and the stress of the collateral. Our Company does not intend to sell, and it is more likely than not that our Company will not be required to sell, these securities before the recovery of the amortized cost basis. For equity securities, our Company also considers our intent to hold securities as part of the process of evaluating whether a decline in fair value represents an other-than-temporary decline in value. Our Company may realize investment losses to the extent our liquidity needs require the disposition of fixed maturity securities in unfavorable interest rate, liquidity or credit spread environments. Significant changes in the factors our Company considers when evaluating investments for impairment losses could result in a significant change in impairment losses reported in the consolidated financial statements.

The contractual maturity dates for fixed maturities categorized by the number of years until maturity as of March 31, 2015 are shown in the following table:

	March 31, 2015
amounts in thousands	Fair Value		Amortized Cos t
Due in one year or less	$	55,121	$	59,300
Due after one year through five years		756,593		746,400
Due after five years through ten years		326,731		315,462
Due after ten years		361,018		346,208
Mortgage- and asset-backed securities		845,762		827,393
Total	$	2,345,225	$	2,294,763

Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Prepayment assumptions associated with the mortgage-backed and asset-backed securities are reviewed on a periodic basis. When changes in prepayment assumptions are deemed necessary as the result of actual prepayments differing from anticipated prepayments, securities are revalued based upon the new prepayment assumptions utilizing the retrospective accounting method. Due to the periodic repayment of principal, the mortgage-backed and asset-backed securities are estimated to have an effective maturity of approximately 4.5 years.

At March 31, 2015, there were 147 fixed maturities in an unrealized loss position, and there were six equity securities in an unrealized loss position. In the above table, the gross unrealized loss for the greater than 12 months category consists primarily of agency and foreign government bonds primarily due to an unfavorable foreign exchange movement. At December 31, 2014, there were 259 fixed maturities in an unrealized loss position, and there were 15 equity securities in an unrealized loss position. The gross unrealized loss for the greater than 12 months category consists primarily of Treasury and agency bonds, due to an increase in interest rates and unfavorable foreign exchange movement.

As of March 31, 2015 and December 31, 2014, the largest unrealized loss by a non-government backed issuer in the investment portfolio was $0.4 million and $0.5 million, respectively.

Our Company analyzes impaired securities quarterly to determine if any are other-than-temporary. The above securities with unrealized losses have been determined to be temporarily impaired based on our evaluation.

For fixed maturities, when assessing whether the amortized cost basis of the security will be recovered, our Company compares the present value of cash flows expected to be collected in relation to the current book value. Any shortfalls of the present value of the cash flows expected to be collected to the amortized cost basis is considered the credit loss portion of OTTI losses and is recognized in earnings. All non-credit losses are recognized as changes in OTTI losses within AOCI.

To determine whether the unrealized loss on structured securities is other-than-temporary, our Company analyzes the projections provided by our investment managers with respect to an expected principal loss under a range of scenarios and utilizes the most likely outcomes. The analysis relies on actual collateral performance measures such as default rate, prepayment rate and loss severity. These assumptions are applied throughout the remaining term of the deal, incorporating the transaction structure and priority of payments, to generate loss adjusted cash flows. Results of the analysis will indicate whether the security is expected ultimately to incur a loss or whether there is a material impact on yield due to either a projected loss or a change in cash flow timing. A break-even default rate is also calculated. A comparison of the break-even default rate to the actual default rate provides an indication of the level of cushion or coverage to the first dollar principal loss. The analysis applies the stated assumptions throughout the remaining term of the transaction to forecast cash flows, which are then applied through the transaction structure to determine whether there is a loss to the security. For securities in which a tranche loss is present and the net present value of loss adjusted cash flows is less than book value, impairment is recognized. The output data also includes a number of additional metrics such as average life remaining, original and current credit support, over 60 day delinquency and security rating.

The significant inputs used to measure the amount of credit loss recognized in earnings were actual delinquency rates, default probability assumptions, severity assumptions and prepayment assumptions. Projected losses are a function of both loss severity and probability of default. Default probability and severity assumptions differ based on property type, vintage and the stress of the collateral. Our Company does not intend to sell, and it is more likely than not that it will not be required to sell, these securities before the recovery of the amortized cost basis.

For equity securities, in general, our Company focuses our attention on those securities with a fair value less than 80% of their cost for six or more consecutive months. If warranted as the result of conditions relating to a particular security, our Company will focus on a significant decline in fair value regardless of the time period involved. Factors considered in evaluating potential impairment include, but are not limited to, the current fair value as compared to cost of the security, the length of time the investment has been below cost and by how much the investment is below cost. If an equity security is deemed to be other-than-temporarily impaired, the cost is written down to fair value with the loss recognized in earnings.

Our Company’s ability to hold securities is supported by sufficient cash flow from our operations and from maturities within our investment portfolio in order to meet our claims payment and other disbursement obligations arising from our underwriting operations without selling such investments. With respect to securities where the decline in value is determined to be temporary and the security’s value is not written down, a subsequent decision may be made to sell that security and realize a loss. Subsequent decisions on security sales are made within the context of overall risk monitoring, changing information and market conditions.

Our Company did not have any credit related OTTI losses during the three months ended March 31, 2015 and 2014.

The following table summarizes the cumulative amounts related to our Company’s credit loss portion of the OTTI losses on fixed maturities for the three months ended March 31, 2015 and 2014. Our Company does not intend to sell, and it is more likely than not that it will not be required to sell, the securities prior to recovery of the amortized cost basis and for which the non-credit loss portion is included in AOCI.

Note 4. Fair Value Measurement

The fair value of our financial instruments is determined based on the following fair value hierarchy:

Level 1 – Quoted prices for identical instruments in active markets. Examples are listed equity and fixed income securities traded on an exchange. U.S. Treasury securities are reported as Level 1 and are valued based on unadjusted quoted prices for identical assets in active markets that our Company can access.

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Examples are asset-backed and mortgage-backed securities that are similar to other asset-backed or mortgage-backed securities observed in the market. U.S. government agency securities are reported as Level 2 and are valued using yields and spreads that are observable in active markets.

Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. An example would be a private placement with minimal liquidity.

15

The following tables present, for each of the fair value hierarchy levels as defined by the accounting guidance for fair value measurements and described below, our Company’s fixed maturities and equity securities by asset class that are measured at fair value on a recurring basis, as well as the fair value of the 5.75% Senior notes due October 15, 2023 (the “Senior notes”) carried at amortized cost as of March 31, 2015 and December 31, 2014:

Our Company did not have any significant transfers between the Level 1 and Level 2 classifications for the three months ended March 31, 2015 and 2014.

16

As of March 31, 2015, our Company did not have any Level 3 assets. For the three months ended March 31, 2014, our Company had one corporate bond for $4.4 million which transferred from Level 3 to Level 2. Our Company was able to obtain a valuation in which all significant inputs to the model are observable in active markets.

Note 5. Ceded Reinsurance

As of March 31, 2015, the credit quality distribution of our Company’s reinsurance recoverables of $1.1 billion for ceded paid losses, ceded unpaid losses and LAE, and ceded unearned premiums based on insurer financial strength ratings from A.M. Best or S&P was not significantly different from the credit quality distribution as of December 31, 2014.

Our allowance for uncollectible reinsurance was $8.2 million and $11.3 million as of March 31, 2015 and December 31, 2014, respectively. The reduction in our allowance for uncollectible reinsurance was the result of payments of outstanding balances from one of our large reinsurers.

As of March 31, 2015, our 20 largest reinsurers measured by the amount of Reinsurance recoverable for ceded losses and LAE and ceded unearned premium, together with the Reinsurance recoverable and collateral, were not significantly different from December 31, 2014.

Credit Facilities

On November 6, 2014, NUAL entered into a credit facility for $8.0 million Australian Dollars with Barclays Bank PLC to fund its participation in the Syndicate. The facility is used to fund Australian underwriting obligations for the 2015 and prior underwriting years. The facility contains customary covenants for facilities of this type, including a restriction on future encumbrances that are outside the ordinary course of business, and a requirement to maintain at least £75 million of Funds at Lloyd’s. Interest is payable on the facility at a rate of 2% per annum above a floating rate tied to the average mid-rate for Australian bills of exchange administered by the Australian Financial Markets Association. The facility may be cancelled by either party after providing written notice. As of March 31, 2015, our Company was in compliance with all covenants.

On November 24, 2014, our Company entered into a $175 million credit facility agreement with ING Bank N.V., London Branch, individually and as Administrative Agent, and a syndicate of lenders. The new credit facility amended and restated a $165 million letter of credit facility entered into by the parties on November 22, 2012. The credit facility, which is denominated in U.S. dollars, is utilized to fund our participation in the Syndicate by posting Funds at Lloyd’s through letters of credit for the 2015 and 2016 underwriting years, as well as open prior years. The letters of credit issued under the facility can be denominated in British pounds and their aggregate face amount will fluctuate based on exchange rates. If any letters of credit remain outstanding under the facility after December 31, 2016, our Company would be required to post additional collateral to secure the remaining letters of credit. As of March 31, 2015, letters of credit with an aggregate face amount of $145.1 million were outstanding under the credit facility and our Company had $1.0 million of cash collateral posted.

This credit facility contains customary covenants for facilities of this type, including restrictions on indebtedness and liens, limitations on mergers, dividends and the sale of assets, and requirements as to maintaining certain consolidated tangible net worth, statutory surplus and other financial ratios. The credit facility also provides for customary events of default, including failure to pay principal, interest or fees when due, failure to comply with covenants, any representation or warranty made by our Company being false in any material respect, default under certain other indebtedness, certain insolvency or receivership events affecting our Company and its subsidiaries, the occurrence of certain material judgments, or a change in control of our Company. The letter of credit facility is secured by a pledge of the stock of certain insurance subsidiaries of our Company. To the extent the aggregate face amount issued under the credit facility exceeds the commitment amount, our Company is required to post collateral with the lead bank of the syndicate of lenders.

The applicable fee rate payable under the credit facility is based on a tiered schedule that is based on our Company’s then-current financial strength ratings issued by S&P and A.M. Best and the amount of our Company’s own collateral utilized to fund its participation in the Syndicate.

Senior notes

The Senior notes had no material changes in the first quarter 2015.

Note 7. Commitments and Contingencies

In 2013, the State of Connecticut (“the State”) awarded our Company up to $11.5 million ($8.0 million in loans and $3.5 million in grants) to move our corporate headquarters to Stamford, Connecticut. The loan is non-interest bearing, has a term of 10 years and is subject to forgiveness based on our compliance with certain conditions set forth in the agreement with the State. The amount of the loan to be received is dependent on our Company reaching certain milestones for creation of new jobs over a five-year period, and the funds are to be used to offset certain equipment purchases, facility costs, training of employees and other eligible project-related costs. Our Company completed the move to Stamford in September 2013 and received $7.5 million of the award, which is comprised of $6.0 million of the loan and $1.5 million of the grant for reaching the first job milestone. Earning of the grant and forgiveness of the loan is subject to certain conditions, including maintaining the required jobs for an extended period of time. As of March 31, 2015, the length of time commitment has not been met. However, our Company expects to meet all the conditions for the state to forgive the amount of the loan received to date, and accordingly, is recognizing the amount of loan and grants received over the period in which our Company recognizes the expenses for which the assistance is intended to compensate as a reduction of such expenses. Our Company recognized $0.2 million of the incentive for each of the three months ended March 31, 2015 and 2014, respectively. As of March 31, 2015 and December 31, 2014, our Company has deferred revenue of $5.9 million and $6.1 million, respectively, which is included in Other liabilities on the Consolidated Balance Sheets.

In the ordinary course of conducting business, our Company’s subsidiaries are involved in various legal proceedings, either indirectly as insurers for parties or directly as defendants. Most of these proceedings consist of claims litigation involving the Company’s subsidiaries as either: (a) liability insurers defending or providing indemnity for third party claims brought against insureds or (b) insurers defending first party coverage claims brought against them. Our Company accounts for such activity through the establishment of unpaid loss and LAE reserves. Our Company’s management believes that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and cost of defense, will not be material to our Company’s Consolidated Balance Sheets, Consolidated Statements of Income or Consolidated Statements of Cash Flows.

Our Company’s subsidiaries are also from time to time involved with other legal actions, some of which assert claims for substantial amounts. These actions include claims asserting extra contractual obligations, such as claims involving allegations of bad faith in the handling of claims or the underwriting of policies. In general, our Company believes it has valid defenses to these cases. Our Company’s management expects that the ultimate liability, if any, with respect to future extra-contractual matters will not be material to our Consolidated Balance Sheets, Consolidated Statements of Income or Consolidated Statements of Cash Flows. Nonetheless, given the large or indeterminate amounts sought in certain of these matters, and the inherent unpredictability of litigation, an adverse outcome in such matters could, from time to time, have a material adverse outcome on our Company’s Consolidated Statements of Income or Consolidated Statements of Cash Flows in a particular fiscal quarter or year.

Note 8. Stock Options, Stock Grants, SARs and ESPP

Stock-based compensation granted under the Company’s stock plans is expensed in tranches over the vesting period. Options and non-performance based grants generally vest equally over a three or four-year period and the options have a maximum term of ten years. Pursuant to the provisions of the Second Amended and Restated 2005 Stock Incentive Plan (“the Plan”), shares that are subject to an award and are forfeited or otherwise terminate without the delivery of the full number of shares may, to the extent of such forfeiture or termination, again be available for grant under the Plan. The Compensation Committee has adopted a policy that shares that are forfeited to satisfy the withholding tax obligations of a grantee, and which have not otherwise been issued or outstanding, will, pursuant to this provision, again be available for grant under the Plan. This policy has been applied effective January 1, 2010.

Restricted stock units and performance units are granted at the market closing price on the grant date. On February 10, 2015, we granted 4,658 restricted stock units and on March 5, 2015, we granted 185,050 performance units to employees and officers with a grant date fair market value of $77.31 and $74.49, respectively. Each performance unit and restricted stock unit represents a contingent right to receive of one share of common stock as of the vesting date.

• risks associated with continued or increased premium levies by Lloyd’s for the Lloyd’s Central Fund and cash calls for trust fund deposits, or a significant downgrade of Lloyd’s rating by the A.M. Best;

• changes in the laws, rules and regulations that apply to our U.S. Insurance Companies;

• the effect of the European Union Directive on Solvency II on how we manage our business, capital requirements and costs associated with conducting business;

• the inability of our subsidiaries to pay dividends to us in sufficient amounts, which would harm our ability to meet our obligations;

19

• weather-related events and other catastrophes (including man-made catastrophes) impacting our insureds and/or reinsurers;

• volatility in the market price of our common stock;

• exposure to recent uncertainties with regard to European sovereign debt holdings;

• the determination of the impairments taken on our investments is subjective and could materially impact our financial position or results of operations;

• if we experience difficulties with our information technology and telecommunications systems and/or data security, our ability to conduct our business might be adversely affected;

• compliance by our Marine business with the legal and regulatory requirements to which they are subject, which are evolving and unpredictable. In addition, compliance with new sanctions and embargo laws could have a material adverse effect on our business; and

• other risks that we identify in current and future filings with the Securities and Exchange Commission (“SEC”).

In light of these risks, uncertainties and assumptions, any forward-looking events discussed in this Form 10-Q may not occur. You are cautioned not to place undue reliance on any forward-looking statements, which speak only as of their respective dates.

OVERVIEW

The discussion and analysis of our financial condition and results of operations contained herein should be read in conjunction with our interim consolidated financial statements as of March 31, 2015. It contains forward-looking statements that involve risks and uncertainties. Please refer to “Note on Forward-Looking Statements” for more information. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those discussed below and elsewhere in this Form 10-Q.

Unless the context requires otherwise, the terms “we,” “us,” “our,” or “our Company” are used to mean The Navigators Group, Inc., a Delaware holding company established in 1982, and its subsidiaries. The terms “Parent” or “Parent Company” are used to mean The Navigators Group, Inc. without its subsidiaries.

We are an international insurance company with a long-standing area of specialization in Marine insurance. Our P&C insurance business primarily offers General Liability coverage and Umbrella & Excess Liability coverage to commercial enterprises through our Primary and Excess Casualty divisions. We have also developed niches in Professional Liability insurance, through our Management Liability and Errors and Omissions divisions. Beginning in 2010, we added reinsurance products through our Assumed Reinsurance division.

Financial Highlights for the Quarter Ended March 31, 2015 and compared to the same period in the prior year

• Net income of $25.9 million, a decrease of 7.3% from prior year

• Earnings per diluted share of $1.77, a decrease of 8.7% from prior year

• Net underwriting profit of $18.2 million, an increase of 3.9% over prior year

• Net investment income of $16.3 million, an decrease of 2.1% from prior year

• Net cash flow used in operations of $4.9 million, a decrease of $13.8 million from prior year

• Annualized return on equity of 10.1%, a decrease of 2.3% from prior year

• Book value of $1.1 billion, an increase of 2.6% over prior year

Our revenue is primarily comprised of premiums and investment income. Cash flow is generated from premiums collected and investment income received less paid losses and loss expenses, policy acquisition costs and administrative expenses. Our products are distributed through multiple channels, utilizing global, national and regional retail and wholesale insurance brokers.

During the first quarter of 2015, we realigned our reporting segments from Insurance Companies, Lloyd’s Operations and Corporate to U.S. Insurance, Int’l Insurance, GlobalRe and Corporate. The new segment presentation reflects an increase in the level of importance that the Chief Operating Decision Maker now places on the results of the underlying operating segments when aggregated and reported in alignment with the products and services offered to the marketplace versus when aggregated and reported in alignment with our legal entity structure. Over the past few years, we have been monitoring the growth and stability of our reinsurance business and in 2015 determined that reinsurance has become a stable and significant component of our Company. We are also increasing our focus on additional international insurance markets by establishing underwriting offices in Continental Europe. The offices were fully operational during our January renewal season. We considered these changes in conjunction with operating and reportable segments. For financial information by segment, refer to Note 2 – Segment Information, in the Notes to Consolidated Financial Statements, included herein.

U.S. GAAP and Non-GAAP Financial Performance Metrics

Throughout this quarterly report, we present our operations in the way we believe will be most meaningful, useful and transparent to anyone using this financial information to evaluate our performance. In addition to the GAAP presentation of net income, we show certain non-GAAP financial measures that we believe are valuable in managing our business and drawing comparisons to our peers. These measures are Underwriting profit (loss), Net operating earnings, Combined ratio, Net losses and LAE and Book value per share.

The following is a list of GAAP and non-GAAP measures found throughout this report with their definitions, relationships to GAAP measures and explanations of their importance to our operations.

Underwriting profit (loss)

Underwriting profit represents one measure of the pretax profitability of our insurance operations and is derived by subtracting losses and LAE, policy acquisition costs and other operating expenses from net premiums earned. This information is available in total and by segment in Note 2 – Segment Information to the interim consolidated financial statements as of March 31, 2015. The nearest comparable GAAP measure is earnings before income taxes which, in addition to net underwriting profit, includes Net investment income, Net OTTI, Net realized gains/losses on investments, Interest expense and Other income (expenses).

Combined ratio

This ratio is a common insurance industry measure of profitability for any underwriting operation and is calculated in two components. First, the loss ratio is losses and settlement expenses divided by net premiums earned. The second component, the expense ratio, reflects the sum of policy acquisition costs and insurance operating expenses, divided by net premiums earned. All items included in these components of the combined ratio are presented in our GAAP financial statements. The sum of the loss and expense ratios is the combined ratio. The difference between the combined ratio and 100 reflects the per-dollar rate of Underwriting profit (loss). For example, a combined ratio of 85 implies that for every $100 of premium we earn, we record $15 of Underwriting profit.

Net losses and LAE

Net losses and LAE, as shown in the liabilities section of our Consolidated Balance Sheets, represents the total obligations to claimants for both estimates of known claims and estimates for incurred but not reported (“IBNR”) claims. The related asset item, Reinsurance balances recoverable on unpaid losses and LAE, is the estimate of known claims and estimates of IBNR that we expect to recover from reinsurers. The net of these two items is generally referred to as net unpaid loss and LAE and is commonly used in our disclosures regarding the process of establishing these various estimated amounts.

Book value and book value per share

Book value is equivalent to Stockholders’ equity and book value per share is calculated by dividing Stockholders’ equity by the number of outstanding shares at any period end.

Net operating earnings

Net operating earnings is calculated as net income less after-tax net realized gains (losses), net OTTI losses recognized in earnings, and after-tax foreign exchange gains and losses resulting from foreign currency transactions (transactions denominated in a currency other than the entity’s functional currency) and translation adjustments (translation of foreign currency denominated assets and liabilities into the entity’s functional currency).

RESULTS OF OPERATIONS

The following is a discussion and analysis of our results of operations for the three months ended March 31, 2015 and 2014.

Summary of Consolidated Results

The following table presents a summary of our consolidated financial results for the three months ended March 31, 2015 and 2014:

	Three Months Ended March 31,						Percentage Change

Combined ratio		92.3	%		92.2	%

NM - Percentage change not meaningful

(1) - Includes Other operating expenses & Other underwriting income (expense)

Gross Written Premiums

Gross written premiums decreased $26.3 million for the quarter ended March 31, 2015 compared to the same period in 2014 primarily due to a $30.5 million decrease in GlobalRe related to the nonrenewal of a significant crop quota share treaty, partially offset by increases in U.S. Insurance and Int’l Insurance.

Average renewal premium rates for the three months ended March 31, 2015 decreased in both U.S. Insurance and Int’l Insurance by 1.2% and 3.4%, respectively, resulting in a net decrease of 2.3% compared to the same period in 2014.

Ceded Written Premiums

Ceded written premiums decreased $3.4 million for the quarter ended March 31, 2015 compared to the same period in 2014 primarily due to changes in our mix of business, inclusive of certain changes in our reinsurance programs.

For each of the three months ended March 31, 2015 and 2014, we recorded $0.5 million and $1.0 million, respectively, of reinsurance reinstatement premiums (“RRPs”).

22

Net Earned Premiums

Net earned premiums increased $10.9 million for the quarter ended March 31, 2015 compared to the same period in 2014. The increase is primarily driven by increased retention resulting from changes in our reinsurance programs in 2014 as well as prior year growth in U.S. Insurance.

Net Losses and LAE

The ratio of Net losses and LAE to net earned premiums (“Losses and LAE ratios”) for the three months ended March 31, 2015 and 2014 is presented in the following table (note: accident year is abbreviated “AY”):

							Point
	Q1 2015			Q1 2014			Change
Net losses and LAE ratio, reported		55.1	%		60.0	%		-4.9
Reinstatement Premiums assumed/(ceded)		-0.1	%		0.4	%		-0.5
Prior AY release/(strengthening)		5.3	%		0.0	%		5.3
Net losses and LAE ratio, adjusted		60.3	%		60.4	%		-0.1

For the three months ended March 31, 2015, we recorded $12.6 million of prior AY reserve releases as compared to $37.9 thousand for the same period in 2014. The releases in 2015 are related to favorable loss emergence from U.S. Insurance and Int’l Insurance as well as provision for uncollectible reinsurance due to payments of outstanding balances from one of our large reinsurers.

Commission Expenses

Commission expenses paid to brokers and agents are generally based on a percentage of gross written premiums and are partially offset by ceding commissions we may receive on ceded written premiums. Commissions are generally deferred and recorded as deferred policy acquisition costs to the extent that they relate to unearned premium. The percentage of Commission expenses to Net earned premiums (“Commission expense ratio”) for the three months ended March 31, 2015 was 13.9% compared to 11.4% for the comparable period during 2014. The change in the Commission expense ratio for the three months ended March 31, 2015 compared to the same period in 2014 is attributed to the changes in the mix of business, as well as changes in our reinsurance programs resulting in less ceding commissions.

Other Operating Expenses

Other operating expenses were $54.9 million for the three months ended March 31, 2015 compared to $47.1 million for the same period in 2014. The increase is primarily due to continued investment in our employee base, resulting in increased salary and related costs, designed to closely align with business growth, expanding our presence in Europe and an increase in incentive compensation driven by improved cumulative financial results over the corresponding prior period.

Net Investment Income

Our net investment income was derived from the following sources:

	Three Months Ended March 31,						Percentage Change
amounts in thousands	2015			2014			YTD
Fixed maturities	$	15,047		$	13,953			7.8	%
Equity securities		1,968			3,233			-39.1	%
Short-term investments		183			218			-16.1	%
Total investment income	$	17,198		$	17,404			-1.2	%
Investment expenses		(945	)		(794	)		19.0	%
Net investment income	$	16,253		$	16,610			-2.1	%

The decrease in total investment income for the three months ended March 31, 2015 as compared to the prior year was primarily due to a $1.6 million one-time special dividend received in the first quarter of 2014 in the equity portfolio. The annualized pre-tax yield, excluding net realized gains and losses and net OTTI losses recognized in earnings, was 2.4% and 2.8% for the three months ended March 31, 2015 and 2014, respectively. Excluding the impact of the one-time special dividend, the pre-tax investment yield for the three months ended March 31, 2014 was 2.5%. The portfolio duration was 3.7 years and 3.6 years at March 31, 2015 and 2014, respectively.

23

The tax equivalent yields for the three months ended March 31, 2015 and 2014 on a consolidated basis were 2.5% and 2.9%, respectively. During 2015, the tax-exempt portion of our investment portfolio has decreased by $9.2 million to approximately 20.8% of the fixed maturities investment portfolio as of March 31, 2015, compared to approximately 21.0% at December 31, 2014.

OTTI Losses Recognized in Earnings

There were no credit related OTTI losses for the three months ended March 31, 2015 and 2014.

Net Realized Gains and Losses

Net realized gains and losses, excluding net OTTI losses recognized in earnings, for the periods indicated were as follows:

	Three Months Ended March 31,						Percentage Change
amounts in thousands	2015			2014			YTD
Fixed maturities:
Gains	$	1,174		$	1,867			-37.1	%
Losses		(572	)		(2,051	)		-72.1	%
Fixed maturities, net	$	602		$	(184	)		NM
Short-term:
Gains	$	8		$	—			NM
Losses		(162	)		—			NM
Short-term, net	$	(154	)	$	—			NM
Equity securities:
Gains	$	6,325		$	1,920			NM
Losses		(1,177	)		(903	)		30.3	%
Equity securities, net	$	5,148		$	1,017			NM
Net realized gains (losses)	$	5,596		$	833			NM

NM - Percentage change not meaningful

Net realized gains and losses are generated as part of the normal ongoing management of our investment portfolio. Net realized gains of $5.6 million for the three months ended March 31, 2015 are primarily due to the sale of equity securities. Net realized gains of $0.8 million for the three months ended March 31, 2014 are primarily due to the sale of government and agency bonds, corporate bonds and equity securities.

Interest Expense

Interest expense of $3.9 million for each of the three months ended March 31, 2015 and 2014 relates to our $265.0 million principal amount of the Senior notes. The effective interest rate related to the Senior notes based on the proceeds net of discount and all issuance costs, approximates 5.86%.

Other Income (Expense)

Other income (expense) is primarily comprised of unrealized and realized foreign exchange gains and losses, commission income and inspection fees. Total other income for the three months ended March 31, 2015 was $2.2 million, as compared to total other income of $10.4 million in the prior year. The prior year was impacted by a $10.0 million foreign currency transaction gain in connection with a change in the functional currency of the Syndicate. See Note 1 – Organizations & Summary of Significant Accounting Policies, for additional information regarding the foreign currency adjustment.

Income Taxes

We recorded an effective tax rate of 32.4% for the three months ended March 31, 2015 compared to 32.3% for the same period in 2014. The income tax provision has been computed based on our estimated annual effective tax rate. Our effective tax rate for the quarter differs from the federal tax rate of 35% principally because of tax-exempt investment income and dividends received deduction.

24

Net Income

Net income for the three months ended March 31, 2015 was $25.9 million or $1.77 per diluted share compared to $28.0 million or $1.94 per diluted share for the three months ended March 31, 2014.

Operating Earnings

The following table presents our operating earnings for the three months ended March 31, 2015 and 2014:

amounts in thousands	2015			2014			QTD
Net income	$	25,929		$	27,968			-7.3	%

Net operating earnings per common share:
Basic		1.46			1.47
Diluted		1.43			1.45

NM - Percentage change not meaningful

Book Value and Book Value Per Share

As of March 31, 2015, our book value was $1.1 billion and our book value per share was $73.21, increasing 1.8% from $71.93 as of December 31, 2014, primarily driven by $25.9 million of Net income for the three months ended March 31, 2015.

Segment Information

Gross Written Premiums

Gross written premiums increased $1.0 million for the quarter ended March 31, 2015 compared to the same period in 2014 due to strong new business production and improving market conditions in our U.S. P&C operating segment, which increased 7.2% as compared to the same period in 2014, specifically driven by our Excess Casualty, Primary Casualty and Environmental divisions, which increased 5.5%, 6.6% and 19.9%, respectively. The aforementioned increases were partially offset by our U.S. Marine and U.S. Professional Liability operating segments, which decreased 5.1% and 19.4%, respectively as compared to the same period in 2014. The decrease in the U.S. Marine operating segment can be attributed to non-renewals across various product lines and the decrease in the U.S. Professional Liability operating segment is driven by our decision to exit the small lawyers professional liability business as well as a decrease in our real estate agents liability business as a result of a program termination.

Average renewal premium rates for U.S. Insurance for the three months ended March 31, 2015 decreased 1.2%, primarily driven by a 7.1% and 0.3% decrease in our U.S. Professional Liability and U.S. P&C operating segments, respectively.

Ceded Written Premiums

Ceded written premiums increased $3.7 million for the quarter ended March 31, 2015 compared to the same period in 2014 due to increased cessions in U.S. Marine of $7.1 million on account of new proportional reinsurance programs including 35% cessions on our U.S. Cargo and U.S. Craft products, respectively, in addition to minor changes to our existing proportional reinsurance programs in response to recent market conditions. Furthermore, U.S. Professional Liability ceded written premium increased $3.1 million as compared to the same period in 2014 due to a new reinsurance program implemented in the fourth quarter of 2014 which includes a 60% cession and additional excess-of-loss on various products within our Errors & Omissions (“E&O”) division. The aforementioned increases were partially offset by a $6.6 million decrease in ceded written premium as compared to the same period in 2014 within our U.S. P&C operating segment due to a decrease in our proportional reinsurance program that supports certain casualty risks.

For the three months ended March 31, 2015, we recorded $1.4 million of reinsurance reinstatement premiums primarily driven by one loss within our U.S. Marine business, as compared to $0.5 million of ceded reinsurance reinstatement premiums reported in the first quarter of 2014.

27

Net Earned Premiums

Net earned premiums increased $15.9 million for the quarter ended March 31, 2015 compared to the same period in 2014. The increase is primarily driven by continued growth in the Excess Casualty and Primary Casualty divisions of the U.S. P&C operating segment compounded with increased retention in the Excess Casualty division. The aforementioned increase was partially offset by decreases in retention in U.S. Marine and U.S. Professional Liability operating segments due to the changes in ceded reinsurance programs as described above and, to a lesser extent, a $0.9 million increase in reinsurance reinstatement premiums as compared to first quarter 2014.

Net Losses and LAE

The changes in Net loss and LAE within U.S. Insurance are primarily driven by prior AY reserve strengthening or releases, as discussed below, and to a lesser extent changes in our mix of business.

The Net loss reserves as of March 31, 2015 and December 31, 2014 are as follows:

U.S. Insurance recorded $6.4 million of net prior AY reserve releases, primarily driven by $4.5 million of reserve releases from our U.S. Marine operating segment due to a decline in large loss activity as well as collections of recoverables previously written off and to a lesser extent, a $1.9 million release of provision for uncollectible reinsurance due to payments of outstanding balances from one of our large reinsurers.

Commission Expenses

The commission expense ratio for the three months ended March 31, 2015 increased 2.6 points as compared to the same period in 2014, primarily driven by decreases in our proportional reinsurance within the Excess Casualty division of our U.S. P&C operating segment, ultimately increasing our net commission expense, partially offset by an increase in cessions within the U.S. Professional Liability operating segment due to changes in our E&O reinsurance program in the fourth quarter of 2014 that have resulted in additional ceding commissions.

Other Operating Expenses

For the three months ended March 31, 2015, Other operating expenses increased $5.7 million as compared to the same period in 2014 primarily driven by continued investment in our underwriting teams and support staff and an increase in incentive compensation driven by improved cumulative financial results over the corresponding prior period.

Gross Written Premiums

Gross written premiums increased $3.2 million for the three months ended March 31, 2015 compared to the same period in 2014. The increase in gross written premium is primarily driven by growth in our Int’l Professional Liability operating segment of $7.1 million, of which $1.4 million relates to our new product line Warranties and Indemnities, $2.7 million of which relates to premium generated by the new European offices. These offices in addition to the London office are seeing strong premium production in the quarter, which is above prior year. Int’l Marine has also increased $5.4 million driven in particular by our Cargo and Hull product with new business being written in the European branches. This has been offset by a $9.3 million decrease in our Int’l P&C operating segment due to adverse market conditions, which saw a decrease in renewal rates of 7.0% for the three months ended March 31 2015.

Average renewal premium rates for our Int’l Insurance segment for the three months ended March 31, 2015 decreased 3.4%, driven by 7.0%, 3.6% and 1.5% decreases in our Int’l P&C, Int’l Professional Liability and Int’l Marine operating segments, respectively.

Ceded Written Premiums

Ceded written premiums decreased $8.3 million for the three months ended March 31, 2015 compared to the same period in 2014. This decrease was primarily caused by changes to our Offshore Energy division proportional reinsurance program within the Int’l P&C operating segment as we are retaining more business.

Net Earned Premiums

Net earned premiums increased $3.5 million for the three months ended March 31, 2015 as compared to the same period in 2014. This increase was due to continued growth in Int’l Professional Liability.

Net Losses and LAE

The changes in Net losses and LAE within Int’l Insurance are primarily driven by prior AY reserve strengthening or releases, as discussed below, and to a lesser extent changes in our mix of business.

Int’l Insurance recorded $6.2 million of prior AY reserve releases primarily driven by $3.4 million and $1.5 million of reserve release in the Int’l Marine and the Int’l P&C operating segments, respectively, in connection with favorable loss emergence and, to a lesser extent, a $1.2 million release of provision for uncollectible reinsurance due to payments of outstanding balances from one of our large reinsurers.

Commission Expenses

The commission expense ratio for the three months ended March 31, 2015 increased 3.1 points as compared to the same period in 2014, primarily driven by changes in our proportional reinsurance programs in the first quarter of 2015, as noted above, which in turn resulted in less ceding commission, and to a lesser extent, a change in our mix of business.

Other Operating Expenses

Other operating expenses increased $1.9 million for the three months ended March 31, 2015 as compared to the same period in 2014, primarily due to investment in new underwriting initiatives in mainland Europe including new underwriting offices in Rotterdam, Milan and Paris, and continued investment in new underwriting teams and support staff in London.

Gross Written Premiums

Gross written premiums decreased $30.5 million, for the three months ended March 31, 2015 compared to the same period in 2014 primarily due to the non-renewal of a significant multiple peril crop quota share treaty within the Agriculture division and lower Assumed RRPs in the Latin America (“LatAm”) and Marine Assumed divisions, offset by year over year written premium increases in the Accident & Health, Professional Liability and Property Treaty divisions, due to improved terms on renewals and new business opportunities.

Ceded Written Premiums

Ceded written premiums increased $1.2 million for the three months ended March 31, 2015 compared to the same period in 2014 primarily due to two additional retrocessional treaties written in the quarter for the LatAm surety business as well as an increase in the P&C retrocessional treaties, which includes the Property Treaty division business.

Net Earned Premiums

Net earned premiums decreased $8.5 million for the three months ended March 31, 2015 compared to the same period in 2014. This decrease was primarily due to the nonrenewal of the crop quota share treaty noted above.

Net Losses and LAE

The changes in Net losses and LAE for GlobalRe are primarily driven by changes in our mix of business.

The Net losses and LAE reserves as of March 31, 2015 and December 31, 2014 are as follows:

The components for Net losses and LAE for the three months ended March 31, 2015 and 2014 are as follows:

	GlobalRe						Point
	Q1 2015			Q1 2014			Change
Net losses and LAE ratio, reported		57.5	%		64.3	%		-6.8
Reinstatement Premiums assumed/(ceded)		0.2	%		3.4	%		-3.2
Prior AY release/(strengthening)		0.0	%		-0.2	%		0.2
Net losses and LAE ratio, adjusted		57.7	%		67.5	%		-9.8

The favorable variance in adjusted Net losses and LAE ratio is primarily driven by less Net earned premiums in the Agriculture division due to the non-renewal of significant multiple peril crop quota share treaty, as well as increases in Net earned premiums from prior UWY in the Professional Liability, LatAm and Int’l Property Treaty divisions, all carrying lower ultimate loss ratios.

Commission Expenses

The Commission expense ratio increased 2.1 points for the three months ended March 31, 2015 compared to the same period in 2014, resulting from the non-renewal of a significant multiple peril crop quota share treaty, which carried a lower commission rate, as well as greater profit commission expenses in the Accident & Health and LatAm divisions.

Other Operating Expenses

Other operating expenses increased $0.1 million for the three months ended March 31, 2015 compared to the same period in 2014. The unfavorable variance is due to increases in LatAm premium taxes, as a result of a higher rate charged on insurance transactions in Ecuador in the first quarter of 2015 as well as an increase in expenses related to support staff closely aligned with business growth in conjunction with an increase in incentive compensation driven by strong prior year underwriting results.

CAPITAL RESOURCES

Our capital resources consist of funds deployed or available to be deployed to support our business operations. As of March 31, 2015 and December 31, 2014, our capital resources were as follows:

	March 31,			December 31,
amounts in thousands	2015			2014
Senior notes	$	263,474		$	263,440
Stockholders’ equity		1,053,603			1,027,224
Total capitalization	$	1,317,077		$	1,290,664
Ratio of debt to total capitalization		20.0	%		20.4	%

We primarily rely upon dividends from our subsidiaries to meet our Parent Company’s obligations. Our Parent Company’s cash obligations primarily consist of semi-annual (April and October) interest payments of $7.6 million on the Senior notes. Going forward, the interest payments may be made from funds held at the Parent Company or dividends from its subsidiaries.

Navigators Insurance Company may pay dividends to the Parent Company out of its statutory earned surplus pursuant to statutory restrictions imposed under the New York insurance law. As of March 31, 2015, the maximum amount available for the payment of dividends by Navigators Insurance Company in 2015 without prior regulatory approval is $90.7 million.

Navigators Corporate Underwriters, Ltd., our wholly-owned corporate member at Lloyd’s, may pay dividends to the Parent Company up to the extent of available profits that have been distributed from the Syndicate. As of March 31, 2015, that amount was $9.4 million (£6.3 million).

On November 24, 2014, our Company entered into a $175.0 million credit facility agreement with ING Bank N.V., London Branch, individually and as Administrative Agent, and a syndicate of lenders to fund our participation in the Syndicate. This new credit facility amended and restated a $165.0 million letter of credit facility entered into by the parties on November 22, 2012. On November 6, 2014, we entered into a second credit facility for $8.0 million Australian Dollars with Barclays Bank PLC to fund the Syndicate’s Australian underwriting obligations. For additional information, refer to Note 6 – Debt, in the Notes to Consolidated Financial Statements, included herein.

Shelf Registration

We generally maintain the ability to issue certain classes of debt and equity securities via a universal shelf registration statement filed with the SEC, which is renewed every three years. The shelf registration provides us the means to access the debt and equity markets relatively quickly. Our current shelf registration, which was filed on April 14, 2015, with the SEC expires in 2018. This report is not an offer to sell or the solicitation of an offer to buy nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state.

LIQUIDITY

Consolidated Cash Flows

Net cash used in operating activities was $4.9 million for the three months ended March 31, 2015 compared to net cash provided by operating activities of $8.8 million for the same period in 2014. The net decrease in cash flow from operations during the quarter is largely attributable to an increase in operating expenses paid resulting from increased headcount associated with the expansion of our business lines in our U.S. Insurance Segment and into new European regions in our Int’l Insurance Segment, offset by increased premium collections.

Net cash provided by investing activities was $4.2 million for the three months ended March 31, 2015 compared to net cash used in investing activities of $40.9 million for the comparable period in 2014. Fluctuations in cash provided by, or used in, investing activities is primarily due to changes in operating cash flows and the associated ongoing management of our investment portfolio.

Net cash provided by financing activities was $0.0 for the three months ended March 31, 2015 compared to $0.6 million for the same period in 2014. The decrease in cash provided by financing activities relates to a reduction in proceeds from the issuance of stock under the employee stock purchase plan.

We believe that the cash flow generated by the operating activities of our subsidiaries will provide sufficient funds for us to meet our liquidity needs over the next twelve months. Beyond the next twelve months, cash flow available to us may be influenced by a variety of factors, including general economic conditions and conditions in the insurance and reinsurance markets, as well as fluctuations from year to year in claims experience.

We believe that we have adequately managed our cash flow requirements related to reinsurance recoveries from their positive cash flows and the use of available short-term funds when applicable. However, there can be no assurances that we will be able to continue to adequately manage such recoveries in the future or that collection disputes or reinsurer insolvencies will not arise that could materially increase the collection time lags or result in recoverable write-offs causing additional incurred losses and liquidity constraints to the Company. The payment of gross claims and related collections from reinsurers with respect to large losses could significantly impact our liquidity needs. However, in general, we expect to collect our paid reinsurance recoverables under the terms described above.

Investments

Invested assets increased from 2014 primarily due to reinvestment of portfolio income collected. As of March 31, 2015, the weighted average rating of our fixed maturities was “AA” by S&P and “Aa” by Moody’s. The entire fixed maturity investment portfolio, except for investments with a fair value of $17.0 million, consists of investment grade bonds. As of March 31, 2015, our portfolio had a duration of 3.7 years. Management periodically projects cash flow of the investment portfolio and other sources in order to maintain the appropriate levels of liquidity in an effort to ensure our ability to satisfy claims that may be incurred in excess of our reserves should the need arise. As of March 31, 2015 and December 31, 2014, all fixed maturities and equity securities held by us were classified as available-for-sale.

As of March 31, 2015 and December 31, 2014, our Company did not have a concentration of greater than 5% of invested assets in a single non-U.S. government-backed issuer.

As of March 31, 2015 and December 31, 2014, fixed maturities for which non-credit OTTI was previously recognized and included in other comprehensive income are now in an unrealized gains position of $0.7 million.

The fair value of our investment portfolio may fluctuate significantly in response to various factors such as changes in interest rates, investment quality ratings, equity prices, foreign exchange rates and credit spreads. We do not have the intent to sell nor is it more likely than not that we will have to sell fixed maturities in unrealized loss positions that are not other-than-temporarily impaired before recovery. For structured securities, default probability and severity assumptions differ based on property type, vintage and the stress of the collateral. We do not intend to sell any of these securities and it is more likely than not that, we will not be required to sell these securities before the recovery of the amortized cost basis. For equity securities, we also consider our intent to hold securities as part of the process of evaluating whether a decline in fair value represents an other-than-temporary decline in value. We may realize investment losses to the extent our liquidity needs require the disposition of fixed maturity securities in unfavorable interest rate, liquidity or credit spread environments. Significant changes in the factors we consider when evaluating investments for impairment losses could result in a significant change in impairment losses reported in the consolidated financial statements.

34

We are a specialty insurance company and periods of moderate economic recession or inflation tend not to have a significant direct effect on our underwriting operations. They do, however, impact our investment portfolio. A decrease in interest rates will tend to decrease our yield and have a positive effect on the fair value of our invested assets. An increase in interest rates will tend to increase our yield and have a negative effect on the fair value of our invested assets.

The contractual maturity dates for fixed maturity securities categorized by the number of years until maturity as of March 31, 2015 are shown in the following table:

	March 31, 2015
	Fair		Amortized
amounts in thousands	Value		Cost
Due in one year or less	$	55,121	$	59,300
Due after one year through five years		756,593		746,400
Due after five years through ten years		326,731		315,462
Due after ten years		361,018		346,208
Mortgage- and asset-backed securities		845,762		827,393
Total	$	2,345,225	$	2,294,763

Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Prepayment assumptions associated with the mortgage-backed and asset-backed securities are reviewed on a periodic basis. When changes in prepayment assumptions are deemed necessary as the result of actual prepayments differing from anticipated prepayments, securities are revalued based upon the new prepayment assumptions utilizing the retrospective accounting method. Due to the periodic repayment of principal, the aggregate amount of mortgage-backed and asset-backed securities is estimated to have an effective maturity of approximately 4.5 years.

The following table sets forth the amount of our fixed maturities as of March 31, 2015 by S&P credit rating or, if an S&P rating is not available, the equivalent Moody’s rating. The total rating is the weighted average quality rating for the fixed maturities portfolio as a whole.

We own $71.4 million of municipal securities which are credit enhanced by various financial guarantors. As of March 31, 2015, the average underlying credit rating for these securities is AA-. There has been no material adverse impact to our investment portfolio or results of operations as a result of downgrades of the credit ratings for several of the financial guarantors.

The following table sets forth our agency mortgage-backed securities and residential mortgage-backed securities (“RMBS”) issued by the Government National Mortgage Association (“GNMA”), Federal National Mortgage Association (“FNMA”) and Federal Home Loan Mortgage Corporation (“FHLMC”) and the quality category (prime, Alternative A-paper (“Alt-A”) and subprime) for all other such investments as of March 31, 2015:

Total residential mortgage-backed securities	$	33,116	$	1,079	$	(117	)	$	32,154

We analyze our mortgage-backed and asset-backed securities by credit quality of the underlying collateral distinguishing between the securities issued by the FNMA, the FHLMC and the GNMA which are Federal government sponsored entities, and the non-FNMA and non-FHLMC securities broken out by prime, Alt-A and subprime collateral. The securities issued by FNMA and FHLMC are the obligations of each respective entity. The U.S. Department of the Treasury has agreed to provide support to FNMA and FHLMC under a Preferred Stock Purchase Agreement by committing to make quarterly payments to these enterprises, if needed, to maintain a zero net worth.

Prime collateral consists of mortgages or other collateral from the most creditworthy borrowers. Alt-A collateral consists of mortgages or other collateral from borrowers which have a risk potential that is greater than prime but less than subprime. The subprime collateral consists of mortgages or other collateral from borrowers with low credit ratings. Such subprime and Alt-A categories are as defined by S&P.

We hold non-sovereign securities where the issuer is located in the Euro Area, an economic and monetary union of certain member states within the European Union that have adopted the Euro as their common currency. As of March 31, 2015, the fair value of such securities was $79.0 million, with an amortized cost of $78.1 million representing 3.2% of our total fixed maturities and equity portfolio. Our largest exposure is in the Netherlands with a total of $40.0 million followed by France with a total of $25.8 million. We have no direct exposure to Greece, Portugal, Italy or Spain within the Euro Area, or Ukraine or Russia at March 31, 2015.

At March 31, 2015, there were 147 fixed maturities in an unrealized loss position, and there were six equity securities in an unrealized loss position. In the above table, the gross unrealized loss for the greater than 12 months category consists primarily of agency and foreign government bonds primarily due to an unfavorable foreign exchange movement. At December 31, 2014, there were 259 fixed maturities in an unrealized loss position and there were 15 equity securities in an unrealized loss position. The gross unrealized loss for the greater than 12 months category consists primarily of Treasury and agency bonds, due to an increase in interest rates and unfavorable foreign exchange movement.

We analyze the unrealized losses quarterly to determine if any are other-than-temporary. The above unrealized losses have been determined to be temporary based on our policies.

As of March 31, 2015 and December 31, 2014, the largest unrealized loss by a non-government backed issuer in the investment portfolio was $0.4 million and $0.5 million, respectively.

38

The following table summarizes the gross unrealized investment losses as of March 31, 2015 by length of time where the fair value was less than 80% of amortized cost:

	March 31, 2015
	Fixed		Equity
amounts in thousands	Maturities		Securities		Total
Less than twelve months	$	2,529	$	—	$	2,529
Longer than twelve months		—		—		—
Total	$	2,529	$	—	$	2,529

The $2.5 million unrealized loss is due to unfavorable foreign exchange movement.

There were no credit related OTTI losses during the three months ended March 31, 2015 and 2014. The significant inputs used to measure the amount of credit loss recognized in earnings were actual delinquency rates, default probability assumptions, severity assumptions and prepayment assumptions. Projected losses are a function of both loss severity and probability of default. Default probability and severity assumptions differ based on property type, vintage and the stress of the collateral. We do not intend to sell any of these securities and it is more likely than not that, we will not be required to sell these securities before the recovery of the amortized cost basis.

CRITICAL ACCOUNTING ESTIMATES

The Company’s Annual Report on Form 10-K for the year ended December 31, 2014 discloses our critical accounting estimates (refer to Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Estimates).

We believe the items that require the most subjective and complex estimates involve the reporting of:

• The reserves for losses and LAE (including losses that have occurred but were not reported to us by the financial reporting date)

• Reinsurance recoverables, including a provision for uncollectible reinsurance

• Written and unearned premium

• The recoverability of deferred tax assets

• The impairment of investment securities

Item 3. Quantitative and Qualitative Disclosures about Market Risk

The following updates our disclosure regarding foreign currency exchange rate risk as previously stated in the Company’s 2014 Annual Report on Form 10-K.

FOREIGN CURRENCY EXCHANGE RATE RISK

We are exposed to foreign currency exchange rate risk primarily related to foreign-denominated cash, cash equivalents and marketable securities (“foreign funds”), premiums receivable, reinsurance recoverables on paid and unpaid losses and LAE as well as reserves for losses and LAE. The principal currencies creating foreign currency exchange risk for our operations are the British pound, the Euro and the Canadian dollar. We manage our foreign currency exchange rate risk primarily through asset-liability matching.

There have been no material changes in foreign exchange rate risk from year end.

39

Item 4. Controls and Procedures

(a) Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, have evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of the end of the period covered by this quarterly report. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of the end of such period the Company’s disclosure controls and procedures are effective in identifying, on a timely basis, material information required to be disclosed in our reports filed or submitted under the Exchange Act.

(b) During the quarter ended March 31, 2015, we implemented a new general ledger system and accounts payable system which were integrated into our financial reporting process. The implementation was not made in response to any deficiency in our internal controls. Implementation of this new system involved changes to our financial reporting procedures and controls. Our management believes that appropriate internal controls are in place with the new system. There have been no other significant changes during our first fiscal quarter in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

(c) In designing and evaluating the disclosure controls and procedures and internal control over financial reporting, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures and internal control over financial reporting must reflect the fact that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

In the ordinary course of conducting business, our subsidiaries are involved in various legal proceedings, either indirectly as insurers for parties or directly as defendants. Most of the these proceedings consist of claims litigation involving our subsidiaries as either (a) liability insurers defending or providing indemnity for third party claims brought against insureds or (b) insurers defending first party coverage claims brought against them. We account for such activity through the establishment of unpaid loss and loss adjustment reserves. Our management believes that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and cost of defense, will not be material to our consolidated financial condition, results of operations, or cash flows.

Our subsidiaries are also from time to time involved with other legal actions, some of which assert claims for substantial amounts. These actions include claims asserting extra-contractual obligations, such as claims involving allegations of bad faith in the handling of claims or the underwriting of policies. In general, we believe we have valid defenses to these cases. Our management expects that the ultimate liability, if any, with respect to such extra-contractual matters will not be material to our consolidated financial position. Nonetheless, given the large or indeterminate amounts sought in certain of these matters, and the inherent unpredictability of litigation, an adverse outcome in such matters could, from time to time, have a material adverse outcome on our consolidated results of operations or cash flows in a particular fiscal quarter or year.

Item 1A. Risk Factors

There have been no material changes from the risk factors as previously disclosed in the Company’s 2014 Annual Report on Form 10-K.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

None

Item 3. Defaults Upon Senior Securities

3.1 “Account” means a bookkeeping account established in the name of each Participant and maintained by the Company to reflect the Participant’s interests under the Plan. A Participant’s Account shall reflect any Elective Deferrals, Excess NQ RSA Contributions, and Excess NQ Match, as adjusted for any earnings, losses, and distributions. A Participant’s Account may be divided into subaccounts as the Plan Administrator deems appropriate.

3.2 “Affiliate” means any corporation, trade, or business which is treated as a single employer with the Company under Sections 414(b) or 414(c) of the Code and any other entity designated by the Plan Administrator as an “Affiliate” for purposes of the Plan.

3.5 “Bonus Compensation” means Compensation earned by a Participant for services rendered by a Participant under any bonus or cash incentive plan maintained by the Company relating to a service period of one year or less, which would be included as compensation under the Savings Plan without regard to the limit under Section 401(a)(17) of the Code.

3.6 “Change of Control” means the occurrence of one or more of the following:

(a) A Change in the Ownership of the Company. A change in ownership of the Company shall occur on the date that any one person, or more than one person acting as a “Group” (as defined below), acquires ownership of stock of the Company that, together with stock held by such person or Group, constitutes more than 50% of the total fair market value or total voting power of the stock of the Company; provided, however, that, if any one person, or more than one person acting as a Group, is considered to own more than 50% of the total fair market value or total voting power of the stock of the Company, the acquisition of additional stock by the same person or persons is not considered to cause a change in the ownership of the Company.

(b) A Change in the Effective Control of the Company. A change in the effective control of the Company occurs on the date that either:

(i) any one person, or more than one person acting as a Group, acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) ownership of stock of the Company possessing 35% or more of the total voting power of the stock of the Company; provided, however, that, if any one person, or more than one person acting as a Group, is considered to effectively control the Company, the acquisition of additional control of the Company by the same person or persons is not considered a change in the effective control of the Company; or

(ii) a majority of the members of the Company’s Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Company’s Board prior to the date of the appointment or election; provided, however, that, if one person, or more than one person acting as a Group, is considered to effectively control the Company, the acquisition of additional control of the Company by the same person or persons is not considered a change in the effective control of the Company.

(c) A Change in the Ownership of a Substantial Portion of the Company’s Assets. A change in the ownership of a substantial portion of the Company’s assets occurs on the date that any one person, or more than one person acting as a Group, acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total Gross Fair Market Value (as defined below) equal to all or substantially all of the total Gross Fair Market Value of all of the assets of the Company immediately prior to such acquisition or acquisitions; provided, however, that, a transfer of assets by the Company is not treated as a change in the ownership of such assets if the assets are transferred to: (i) a stockholder of the Company (immediately before the asset transfer) in exchange for or with respect to its stock; (ii) an entity, 50% or more of the total value or voting power of which is owned, directly or indirectly, by the Company; (iii) a person, or more than one person acting as a Group, that owns, directly or indirectly, 50% or more of the total value or voting power of all the outstanding stock of the Company; or (iv) an entity, at least 50% of the total value or voting power of which is owned, directly or indirectly, by a person described in clause (iii) of this subsection (c).

For the avoidance of doubt, an Employee must be employed by the Company as an Eligible Employee and must have established performance goals in writing, in each case no later than 90 days after the commencement of the performance period, in order to make an election to defer “performance-based compensation” under this subsection (c).

(a) Eligible Employee Deferrals. An Eligible Employee may make an election during the Election Period to defer receipt of the Eligible Employee’s Deferral Compensation for the Plan Year (“Voluntary NQ Salary Deferrals”) and/or the Eligible Employee’s Bonus Compensation for the Plan Year (“Voluntary NQ Bonus Deferrals”), in accordance with the Deferral Election procedures as set forth in this Section 5.

The Deferral Election shall also specify a Specified Date or Retirement as the Payment Event with respect to Voluntary NQ Salary Deferrals and/or Voluntary NQ Bonus Deferrals, and the form of payment for such deferrals, including the form of payment upon Retirement, in accordance with Sections 9.2, 9.4, and 9.6.

(b) Eligible Executive Deferrals. An Eligible Executive may elect to defer receipt of up to 4% of the Eligible Executive’s Eligible Compensation for the Plan Year (“Excess NQ Salary Deferrals”), in accordance with the Deferral Election procedures as set forth in this Section 5. The Deferral Election must specify the percentage of Eligible Compensation to be deferred (subject to any minimum and maximum amounts as set forth in this Section 5). The Deferral Election must also specify a form of payment for such Excess NQ Salary Deferrals payable upon Retirement, in accordance with Sections 9.2 and 9.6, provided that such election as to the form of payment will also apply to any Excess NQ Match and Excess NQ RSA Contribution for such Plan Year. If an Eligible Executive does not elect to defer Eligible Compensation for a Plan Year but is eligible to receive an Excess NQ RSA Contribution for such Plan Year and does not specify a form of payment for such Excess NQ RSA Contribution during the Election Period for the Eligible Compensation to which the Excess NQ RSA Contribution relates, such Excess NQ RSA Contribution shall be payable in a lump sum payment in accordance with Section 9.3. An Excess NQ Match shall only be made with respect to Excess NQ Salary Deferrals, in accordance with Section 6.1.

5.2 Maximum Elective Deferral. Unless otherwise specified by the Plan Administrator, the maximum Voluntary NQ Salary Deferrals and Voluntary NQ Bonus Deferrals that a Participant may make for a Plan Year under Section 5.1, when aggregated, may not exceed (a) 50% of the Participant’s Deferral Compensation for the Plan Year and (b) 90% of the Participant’s Bonus Compensation for the Plan Year.

5.3 Plan Year Elections. A separate Deferral Election must be filed for each Plan Year.

5.4 Account Accrual. Elective Deferrals pursuant to this Section 5 shall be credited by the Plan Administrator to the Participant’s Account as soon as practicable after the date on which such Compensation would otherwise have been paid to the Participant, in accordance with the Participant’s election.

6. Excess NQ Match and Excess NQ RSA Contribution.

6.1 Excess NQ Match. Each Plan Year the Company will make an Excess NQ Match to the Plan on behalf of an Eligible Executive in an amount equal to 100% of the Eligible Executive’s Excess NQ Salary Deferrals for such Plan Year up to 4% of the Participant’s Eligible Compensation for such Plan Year. Unless otherwise specified by the Plan Administrator, any Excess NQ Match shall be credited to the Participant’s Account in a manner consistent with that in which a matching contribution would have been made by the Company on the Participant’s behalf to the Savings Plan. Only Eligible Executives shall be eligible to receive an Excess NQ Match.

6.2 Excess NQ RSA Contribution.

(a) Each Plan Year the Company will make an Excess NQ RSA Contribution to the Account of each Eligible Executive in an amount equal to 5% of the Eligible Executive’s Eligible Compensation (less Bonus Compensation and commissions) for such Plan Year, provided that the Eligible Executive is employed by the Company on the last day of the Plan Year in question, except as provided in subsection (b) below. Only Eligible Executives shall be eligible to receive an Excess NQ RSA Contribution for a Plan Year. Any Excess NQ RSA Contribution shall be credited to the Participant’s Account at such time as determined by the Plan Administrator in its discretion.

(b) Notwithstanding subsection (a) above, if during a Plan Year a Participant has a Separation from Service due to death, Retirement, or Disability, the Participant (or the Participant’s Beneficiary in the case of death) will be eligible to receive an Excess NQ RSA Contribution for the Plan Year in which the Participant’s Separation from Service due to death, Retirement, or Disability occurs, which amount will be credited to the Participant’s Account at the time of the Participant’s Separation from Service due to death, Retirement, or Disability, as applicable.

5

7. Accounts and Investments.

7.1 Establishment of Accounts. The Company shall establish and maintain an Account or subaccount for each Participant. The Company may establish more than one Account on behalf of any Participant as deemed necessary by the Plan Administrator for administrative purposes.

7.2 Investment Earnings.

(a) The Participant shall designate, at a time and in a manner acceptable to the Plan Administrator, one or more Investment Funds for his or her Account for the sole purpose of determining the deemed earnings to be credited or debited to such Account. A Participant may change the Investment Fund election applicable to the Participant’s Account and may reallocate the balance in each Investment Fund among the other available Investment Funds, in accordance with procedures established by the Plan Administrator. Notwithstanding the foregoing, the Participant’s Account balance may be reduced by any applicable investment fees, including fees imposed upon a Participant’s reallocation of his or her investment allocations.

(b) If the Participant fails to designate any Investment Funds, his or her Account shall be invested in the default Investment Fund established under the Savings Plan or such other Investment Fund designated by the Plan Administrator.

(c) The Plan Administrator may change the deemed Investment Funds at any time. In addition, any change in the Investment Funds available under the Savings Plan shall automatically result in a corresponding change in the Investment Funds available under this Plan, unless determined otherwise by the Plan Administrator. Upon any change in the Investment Funds, each Participant shall have the opportunity to select among such new Investment Funds as are designated by the Plan Administrator. In case of failure to elect such new Investment Funds, the Participant shall be deemed to have made an election to invest his or her Account in the investment options then being offered that are most comparable to the Participant’s old investment options. The decision of comparable investment options shall be made in the sole discretion of the Plan Administrator.

(d) The Company and its Affiliates, the Board, and the Plan Administrator do not represent or guarantee successful deemed investment of any amounts under the Plan and shall not be required to restore any loss which may result from such deemed investments or lack of investment.

7.3 Nature of Accounts. Accounts may not actually be invested in the Investment Funds and Participants do not have any real or beneficial ownership in the Investment Funds prior to a Payment Event. A Participant’s Account is solely a device for the measurement and determination of the amounts to be paid to the Participant pursuant to the Plan and shall not constitute or be treated as a trust fund of any kind.

7.4 Statements. Each Participant shall be provided with statements or access to statements setting out the amounts in his or her Account(s), which shall be delivered or made available at such intervals determined by the Plan Administrator, and shall reflect the value of the Account balance on the applicable valuation date.

7.5 Ownership of Amounts. The Company may, but shall not be required, to establish and maintain a trust to provide a convenient method of setting aside sufficient assets to meet some or all of its future obligations under the Plan. All property and rights purchased with amounts set aside in the fund and all income attributable to such amounts, property, or rights, shall remain (until paid to the Participant or Beneficiary) solely the property of the Company, and subject only to the claims of the Company’s general creditors. The obligation of the Company to make payments pursuant to the Plan is contractual only, and neither the Participant nor any Beneficiary shall have a preferred claim or lien on or to any assets of the trust but shall have only the right to receive the benefits payable under the Plan.

8. Vesting.

8.1 Vesting of Elective Deferrals. Participants shall be fully vested at all times in their Elective Deferrals and any earnings thereon.

6

8.2 Vesting of Excess NQ Match. Unless determined otherwise by the Plan Administrator, Participants shall be fully vested in their Excess NQ Match, and any earnings thereon.

8.3 Vesting of Excess NQ RSA Contributions. Unless determined otherwise by the Plan Administrator, Participants shall become vested in Excess NQ RSA Contributions, and any earnings thereon, as follows: (a) 0% vested after one Year of Service; (b) 20% vested after two Years of Service; (c) 40% vested after three Years of Service; (d) 60% vested after four Years of Service; (e) 80% vested after five Years of Service; and (f) 100% vested after six Years of Service.

8.4 Vesting upon Death, Disability, or Retirement. Notwithstanding anything to the contrary, a Participant’s unvested Account balance shall become fully vested upon the Participant’s Separation from Service due to death, Disability, or Retirement.

8.5 Vesting upon a Change of Control. Notwithstanding anything to the contrary, a Participant’s unvested Account balance shall become fully vested upon a Change of Control.

9. Distribution of Participant Accounts.

9.1 In General. Distribution of a Participant’s vested Account shall be made or commence on the earliest to occur of the following events (each a “Payment Event”), subject to the six-month delay requirement set forth in Section 13.4(b):

(a) the Participant’s Separation from Service (including Retirement);

(b) the Participant’s death;

(c) a Specified Date (if applicable); or

(d) a Change of Control.

9.2 Form of Payment.

(a) Except as provided in subsections (b) and (c) below, the Participant’s vested Account shall be paid in a lump sum.

(b) Notwithstanding subsection (a), a Participant may elect on the Deferral Election form during the Election Period to receive Specified Date Payments in a single lump sum payment or annual installment payments over a term of at least two years and up to four years. The election under this subsection (b) shall be irrevocably elected in the Participant’s Deferral Election as described in Section 5, subject to Section 10. If a Participant makes an election under Section 9.4 and does not make an election as to the form of payment, such Specified Date Payments, as adjusted for any earnings, losses, or distributions, will be paid in a single lump sum. For each Plan Year a Participant may make a separate election as to the form of payment for the Voluntary NQ Salary Deferrals and Voluntary NQ Bonus Deferrals for such Plan Year.

(c) Notwithstanding subsection (a), a Participant may elect on the Deferral Election form during the Election Period to receive the Excess NQ Salary Deferrals, Excess NQ Match, and Excess NQ RSA Contribution for the Plan Year that become payable upon the Participant’s Retirement, and/or the Voluntary NQ Salary Deferrals and Voluntary NQ Bonus Deferrals that become payable upon the Participant’s Retirement, in a single lump sum payment or annual installment payments over a term of at least two years and up to five years. The election under this subsection (c) shall be irrevocably elected in the Participant’s Deferral Election as described in Section 5, subject to Section 10. For each Plan Year a Participant may only make one election as to the form of payment that will apply to the Excess NQ Salary Deferrals, Excess NQ Match, and Excess NQ RSA Contribution for such Plan Year. For each Plan Year a Participant may make a separate election as to the form of payment that will apply to the Voluntary NQ Salary Deferrals and Voluntary Bonus Deferrals for such Plan Year.

9.3 Timing of Distributions. Unless Section 9.4, 9.5, or 9.6 applies, distribution shall be made within 60 days following the Payment Event, subject to the six-month delay requirement set forth in Section 13.4(b).

9.4 Specified Date for Voluntary NQ Salary and Bonus Deferrals. For each Plan Year, an Eligible Employee may elect, in accordance with the Deferral Election procedures set forth in Section 5, to receive Voluntary NQ Salary Deferrals and/or Voluntary NQ Bonus Deferrals on a Specified Date, subject to Section 9.5. Except as otherwise provided in Sections 9.5 and 10, a Specified Date Payment shall be made, or shall commence, during the payment year designated by the Participant in the applicable Deferral

7

Election form. A Specified Date Payment may not begin any earlier than the second Plan Year following the Plan Year for which the initial filing of the Deferral Election was made with respect to that Specified Date Payment. A Specified Date Payment may not begin more than 20 years following the Plan Year for which the initial filing of the Deferral Election was made with respect to that Specified Date Payment.

9.5 Specified Date Payments Following Separation From Service Date. Except as provided in Section 9.6, if a Participant’s Separation from Service occurs before the year elected by the Participant for one or more Specified Date Payments, then notwithstanding the Participant’s election on any Deferral Election form with respect to the Specified Date Payments, the Participant’s Specified Date Payments shall be paid in a single lump sum payment within 60 days following the Participant’s Separation from Service, subject to the six-month delay requirement set forth in Section 13.4(b). For the avoidance of doubt, except as provided in Section 9.6, if a Participant elects to receive payments in installments in accordance with Section 9.2(b) beginning on a Specified Date, and the Participant has a Separation from Service after the installment payments have begun, the payments will not continue on the regularly scheduled payment dates and will instead be accelerated and paid upon the Participant’s Separation from Service, subject to the six-month delay requirement set forth in Section 13.4(b).

9.6 Payment upon Retirement. Notwithstanding anything to the contrary, for each Plan Year, an Eligible Employee may elect, in accordance with the Deferral Election procedures set forth in Section 5, to receive the Excess NQ Salary Deferrals, Excess NQ Match, and Excess NQ RSA Contribution payable upon Retirement, and/or the Voluntary NQ Salary Deferrals and Voluntary NQ Bonus Deferrals payable upon Retirement, in the form specified in Section 9.2(c). Except as otherwise provided in Sections 9.5 and 10, such payments shall commence within 60 days following the Participant’s Retirement, subject to the six-month delay requirement set forth in Section 13.4(b), and, if the Participant elects to receive payments in installments in accordance with Section 9.2(c), subsequent installments will be made beginning in the year following the year of the Participant’s Retirement. Any election under this Section 9.6 shall supersede Section 9.5. For each Plan Year a Participant may only make one election as to the form of payment that will apply to the Excess NQ Salary Deferrals, Excess NQ Match, and Excess NQ RSA Contribution for such Plan Year upon Retirement. For each Plan Year a Participant may make a separate election as to the form of payment that will apply to the Voluntary NQ Salary Deferrals and Voluntary NQ Bonus Deferrals for such Plan Year upon Retirement. Notwithstanding anything to the contrary, if a Participant elects to receive payments in installments in accordance with Section 9.2(b) beginning on a Specified Date, and the Participant has a Retirement after the installment payments have begun, the payments will continue on the regularly scheduled payment dates.

9.7 Timing of Valuation. The value of a Participant’s Account for distribution shall be determined as of the applicable Payment Event. Notwithstanding the foregoing, if a Participant elects installment payments under Section 9.2, the first annual installment payment in a series of installment payments shall be equal to (a) the value of the Participant’s Account (or relevant portion thereof) on the date of distribution of the first installment payment, divided by (b) the number of installment payments elected by the Participant. The remaining installments shall be paid, respectively, in an amount equal to (x) the value of such Account (or relevant portion thereof) on the distribution date of the installment payment, divided by (y) the number of remaining unpaid installment payments.

9.8 Forfeiture of Unvested Accounts. Unless otherwise determined by the Plan Administrator, a Participant’s unvested Account balance shall be forfeited upon the occurrence of a Payment Event.

9.9 Unforeseeable Emergency. Notwithstanding this Section 9, a Participant may elect to be paid all or any part of the Participant’s vested Account in the event such funds are needed in connection with an “unforeseeable emergency” (as determined by the Plan Administrator in accordance with Section 409A of the Code and other applicable law). For purposes of this Section 9.9, an “unforeseeable emergency” is a severe financial hardship to the Participant resulting from an illness or accident of the Participant, the Participant’s spouse, the Participant’s beneficiary, or the Participant’s dependent (as defined in Section 152 of the Code, without regard to sections 152(b)(1), (b)(2), and (d)(1)(B)), loss of the Participant’s property due to casualty (including the need to rebuild a home following damage to a home not otherwise covered by insurance), or other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the control of the Participant. Unforeseeable emergency shall be administered in accordance with Section 409A of the Code.

9.10 Change in Election. A Participant may change the payment year and/or the form of payment for an existing Specified Date Payment election for a Plan Year, in accordance with Section 409A of the Code, by filing a new payment election, in the form specified by the Plan Administrator, at least 12 months prior to the beginning of the year originally specified by the Participant with respect to such Specified Date Payment (in the case of installment payments, the date of the first scheduled installment payment), provided that (a) such new election delays the payment year by at least five years from the original payment year, and (b) such change in election shall not be effective until 12 months from the date it is filed.

10. Permissible Acceleration and Delays.

10.1 The Company reserves the right, exercisable in its sole discretion, to accelerate payments under this Plan to the extent permitted by, and in accordance with, Treasury Regulation Section 1.409A-3(j)(4). In addition, the Company reserves the right, exercisable in its sole discretion, to delay payments under this Plan to the extent permitted by, and in accordance with, Treasury Regulation Section 1.409A-2(b)(7).

10.2 Without limiting Section 10.1, the Plan Administrator may accelerate distribution of a Participant’s vested Account to the extent that (a) the aggregate amount in the Participant’s Account does not exceed the applicable dollar amount under Section 402(g)(1)(B) of the Code, (b) the distribution results in the termination of the Participant’s entire interest in the Plan and any plans that are aggregated with the Plan pursuant to Treas. Reg. Section 1.409A-1(c)(2), and (c) the Plan Administrator’s decision to cash out the Participant’s Account is evidenced in writing no later than the date of distribution.

11. Plan Administration.

11.1 Administration By Plan Administrator. The Plan shall be administered by the Plan Administrator, which shall have the authority to:

(a) construe and interpret the Plan and apply its provisions;

(b) promulgate, amend, and rescind rules and regulations relating to the administration of the Plan;

(c) authorize any person to execute, on behalf of the Company, any instrument required to carry out the purposes of the Plan;

(d) determine minimum or maximum amounts, and the types of compensation, that Participants may elect to defer under the Plan;

(e) determine the amount of any Excess NQ Match and Excess NQ RSA Contributions with respect to any Plan Year, in accordance with the terms of the Plan;

(f) select, subject to the limitations set forth in the Plan, those Employees who shall be Eligible Employees and Eligible Executives;

(g) calculate deemed earnings and losses on Accounts;

(h) interpret, administer, reconcile any inconsistency in, correct any defect in, and/or supply any omission in the Plan and any instrument, Deferral Election, or agreement relating to the Plan; and

(i) exercise discretion to make any and all other determinations which it determines to be necessary or advisable for the administration of the Plan.

11.2 Non-Uniform Treatment. The Plan Administrator’s determinations under the Plan need not be uniform and any such determinations may be made selectively among Participants. Without limiting the generality of the foregoing, the Plan Administrator shall be entitled, among other things, to make non-uniform and selective determinations with regard to: (a) the terms or conditions of any Elective Deferral; or (b) the amount, terms, or conditions of any Excess NQ Match or Excess NQ RSA Contribution, in accordance with the Plan terms.

11.3 Plan Administrator Decisions Final. Subject to Section 14, all decisions made by the Plan Administrator pursuant to the provisions of the Plan shall be final and binding on the Company and the Participants and Beneficiaries, unless such decisions are determined by a court having jurisdiction to be arbitrary and capricious.

11.4 Indemnification. Neither the Plan Administrator nor any designee shall be liable for any action, failure to act, determination, or interpretation made in good faith with respect to the Plan except for any liability arising from his or her own wilful malfeasance, gross negligence, or reckless disregard of his or her duties.

9

12. Amendment and Termination. Subject to the applicable requirements of Section 409A of the Code, the Board, or any committee designated by the Board, may, at any time, and in its discretion, alter, amend, modify, suspend, or terminate the Plan or any portion thereof, provided, however, that no such alteration, amendment, modification, suspension, or termination shall, without the consent of a Participant, reduce the amounts credited to the Participant’s Account as of such date.

13. Miscellaneous.

13.1 No Employment or Other Service Rights. Nothing in the Plan or any instrument executed pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate or interfere in any way with the right of the Company or any Affiliate to terminate the Participant’s employment or service at any time with or without notice and with or without cause.

13.2 Tax Withholding. The Company and its Affiliates shall have the right to deduct from any amounts otherwise payable under the Plan any federal, state, local, or other applicable taxes required to be withheld.

13.3 Governing Law. The Plan shall be administered, construed, and governed in all respects under and by the laws of the State of New York, without reference to the principles of conflicts of law (except and to the extent pre-empted by applicable Federal law).

13.4 Section 409A of the Code.

(a) The Company intends that the Plan comply with the requirements of Section 409A of the Code and shall be operated and interpreted consistent with that intent. Notwithstanding anything in the Plan to the contrary, distributions may only be made under the Plan upon an event and in a manner permitted by Section 409A of the Code. In no event shall a Participant, directly or indirectly, designate the calendar year of payment, except as permitted by Section 409A of the Code.

(b) Notwithstanding anything in the Plan to the contrary, if a Participant’s distribution is to be paid upon separation from service, payment of the distribution shall be delayed for a period of six months after the Participant’s separation from service, if the Participant is a “specified employee” as defined under Section 409A of the Code (as determined by the Plan Administrator) and if required pursuant to Section 409A of the Code (“six-month delay”). If payment is delayed, the Participant’s distribution shall be paid within 30 days of the date that is the six-month anniversary of the Participant’s separation from service, or death if earlier.

(c) Notwithstanding the foregoing, the Company makes no representation that the Plan complies with Section 409A of the Code and shall have no liability to any Participant or Beneficiary for any failure to comply with Section 409A of the Code.

(d) This Plan shall constitute an “account balance plan” as defined in Treasury Regulation Section 31.3121(v)(2)-1(c)(1)(ii)(A). For purposes of Section 409A of the Code, all amounts deferred under this Plan shall be aggregated with amounts deferred under other account balance plans.

13.5 No Warranties. Neither the Company nor the Plan Administrator warrants or represents that the value of any Participant’s Account will increase. Each Participant assumes the risk in connection with the deemed investment of his or her Account.

13.6 Beneficiary Designation. Each Participant under the Plan may from time to time name any beneficiary or beneficiaries to receive the Participant’s interest in the Plan in the event of the Participant’s death. Each designation will revoke all prior designations by the same Participant, shall be in a form reasonably prescribed by the Plan Administrator, and shall be effective only when filed by the Participant in writing with the Company during the Participant’s lifetime. If a Participant fails to designate a beneficiary, then the Participant’s designated beneficiary shall be deemed to be the Participant’s estate.

13.7 No Assignment. Neither a Participant nor any other person shall have any right to sell, assign, transfer, pledge, anticipate, or otherwise encumber, transfer, hypothecate, or convey any amounts payable hereunder prior to the date that such amounts are paid (except for the designation of beneficiaries pursuant to Section 13.6).

13.8 Expenses. The costs of administering the Plan shall be charged to Participant Accounts, unless paid for by the Company, as determined by the Company in its discretion.

10

13.9 Severability. If any provision of the Plan is held to be invalid, illegal, or unenforceable, whether in whole or in part, such provision shall be deemed modified to the extent of such invalidity, illegality, or unenforceability and the remaining provisions shall not be affected.

13.10 Headings and Subheadings. Headings and subheadings in the Plan are for convenience only and are not to be considered in the construction of the provisions hereof.

14. Claims Procedures.

14.1 Filing a Claim. Any Participant or other person claiming an interest in the Plan (the “Claimant”) may file a claim in writing with the Plan Administrator. The Plan Administrator shall review the claim itself or appoint an individual or entity to review the claim.

14.2 Claim Decision. The Claimant shall be notified within 90 days after the claim is filed whether the claim is approved or denied, unless the Plan Administrator determines that special circumstances beyond the control of the Plan require an extension of time, in which case the Plan Administrator may have up to an additional 90 days to process the claim. If the Plan Administrator determines that an extension of time for processing is required, the Plan Administrator shall furnish written or electronic notice of the extension to the Claimant before the end of the initial 90 day period. Any notice of extension shall describe the special circumstances necessitating the additional time and the date by which the Plan Administrator expects to render its decision.

14.3 Notice of Denial. If the Plan Administrator denies the claim, it must provide to the Claimant, in writing or by electronic communication, a notice which includes:

(a) The specific reason(s) for the denial;

(e) If an internal rule was relied on to make the decision, either a copy of the internal rule or a statement that this information is available at no charge upon request.

14.4 Appeal Procedures. A request for appeal of a denied claim must be made in writing to the Plan Administrator within 60 days after receiving notice of denial. The decision on appeal will be made within 60 days after the Plan Administrator’s receipt of a request for appeal, unless special circumstances require an extension of time for processing, in which case a decision will be rendered not later than 120 days after receipt of a request for appeal. A notice of such an extension must be provided to the Claimant within the initial 60 day period and must explain the special circumstances and provide an expected date of decision. The reviewer shall afford the Claimant an opportunity to review and receive, without charge, all relevant documents, information and records and to submit issues and comments in writing to the Plan Administrator. The reviewer shall take into account all comments, documents, records, and other information submitted by the Claimant relating to the claim regardless of whether the information was submitted or considered in the initial benefit determination.

14.5 Notice of Decision on Appeal. If the Plan Administrator denies the appeal, it must provide to the Claimant, in writing or by electronic communication, a notice which includes:

(a) The specific reason(s) for the denial;

(b) Specific references to the pertinent Plan provisions on which such denial is based;

(c) A statement that the Claimant may receive on request all relevant records at no charge;

(d) A description of the Plan’s voluntary procedures and deadlines, if any;

11

(e) A statement of the Claimant’s right to sue under Section 502(a) of ERISA; and

Organization and Summary of Significant Accounting Policies

Note 1. Organization and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying interim consolidated financial statements are unaudited and reflect all adjustments which, in the opinion of management, are necessary to fairly present the results of The Navigators Group, Inc. and its subsidiaries for the interim periods presented on the basis of United States generally accepted accounting principles (“GAAP” or “U.S. GAAP”). All significant intercompany transactions and balances have been eliminated in consolidation. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported revenues and expenses during the reporting periods. The results of operations for any interim period are not necessarily indicative of results for the full year. The interim consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2014. Certain amounts for the prior year have been reclassified to conform with the current period presentation. Unless the context requires otherwise, the terms “we,” “us,” “our,” or “our Company” are used to mean The Navigators Group, Inc., a Delaware holding company established in 1982, and its subsidiaries. The terms “Parent” or “Parent Company” are used to mean The Navigators Group, Inc. without its subsidiaries.

Organization

We are an international insurance company with a long-standing area of specialization in Marine insurance. Our Property and Casualty (“P&C”) insurance business primarily offers General Liability coverage and Umbrella & Excess Liability coverage to commercial enterprises through our Primary and Excess Casualty divisions. We have also developed niches in Professional Liability insurance, through our Management Liability and Errors and Omissions divisions. Beginning in 2010, we added reinsurance products through our Assumed Reinsurance division.

We operate through various wholly-owned subsidiaries, including Navigators Insurance Company, inclusive of its United Kingdom Branch (“U.K. Branch”), and Navigators Specialty Insurance Company, both of which are U.S. insurance companies, and Navigators Underwriting Agency Ltd., a Lloyd’s of London (“Lloyd’s”) underwriting agency that manages Lloyd’s Syndicate 1221 (“the Syndicate”) in the U.K. The Company controls 100% of the Syndicate’s stamp capacity.

Foreign Exchange Remeasurement and Translation

During the first quarter of 2014, the Syndicate revised its foreign exchange accounting methodology from reporting its financial position and results using three functional currencies (GBP, USD and CAD) to one functional currency (USD). The USD was chosen as the single functional currency as the majority of the Syndicate’s insurance business has been and continues to be transacted in USD. This cumulative change in remeasurement has resulted in an immaterial correction of $10.0 million ($6.6 million after-tax) in Accumulated other comprehensive income (“AOCI”), on the Consolidated Balance Sheets, offset by a gain in Other income in the Consolidated Statements of Income.

Catastrophe Risk Management

We have exposure to losses caused by hurricanes, earthquakes, and other natural and man-made catastrophic events. The frequency and severity of catastrophic events is unpredictable. The extent of covered losses from a catastrophe is a function of both the total amount of insured exposure in an area affected by the event and the severity of the event. We had no material catastrophic events occur in the first quarter 2015.

Income Taxes

The income tax provision has been computed based on our estimated annual effective tax rate. Our effective tax rate for the quarter differs from the federal tax rate of 35% principally because of tax-exempt investment income and dividends received deduction.

Current and Pending Accounting Pronouncements

As of January 1, 2015, we did not adopt any new accounting pronouncements. In April 2015, the Financial Accounting Standards Board issued a new pronouncement, Accounting Standards Update 2015-03 – Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs, which will be effective for fiscal years beginning after December 15, 2015. The new pronouncement was issued to simplify presentation of debt issuance costs. We are assessing the future impact of this update to our Consolidated Financial Statements. There were no additional pending accounting pronouncements that are expected to have a significant impact on the consolidated financial statements upon adoption.

Organization and Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2015

Basis of Presentation

Basis of Presentation

The accompanying interim consolidated financial statements are unaudited and reflect all adjustments which, in the opinion of management, are necessary to fairly present the results of The Navigators Group, Inc. and its subsidiaries for the interim periods presented on the basis of United States generally accepted accounting principles (“GAAP” or “U.S. GAAP”). All significant intercompany transactions and balances have been eliminated in consolidation. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported revenues and expenses during the reporting periods. The results of operations for any interim period are not necessarily indicative of results for the full year. The interim consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2014. Certain amounts for the prior year have been reclassified to conform with the current period presentation. Unless the context requires otherwise, the terms “we,” “us,” “our,” or “our Company” are used to mean The Navigators Group, Inc., a Delaware holding company established in 1982, and its subsidiaries. The terms “Parent” or “Parent Company” are used to mean The Navigators Group, Inc. without its subsidiaries.

Organization

Organization

We are an international insurance company with a long-standing area of specialization in Marine insurance. Our Property and Casualty (“P&C”) insurance business primarily offers General Liability coverage and Umbrella & Excess Liability coverage to commercial enterprises through our Primary and Excess Casualty divisions. We have also developed niches in Professional Liability insurance, through our Management Liability and Errors and Omissions divisions. Beginning in 2010, we added reinsurance products through our Assumed Reinsurance division.

We operate through various wholly-owned subsidiaries, including Navigators Insurance Company, inclusive of its United Kingdom Branch (“U.K. Branch”), and Navigators Specialty Insurance Company, both of which are U.S. insurance companies, and Navigators Underwriting Agency Ltd., a Lloyd’s of London (“Lloyd’s”) underwriting agency that manages Lloyd’s Syndicate 1221 (“the Syndicate”) in the U.K. The Company controls 100% of the Syndicate’s stamp capacity.

Foreign Exchange Remeasurement and Translation

Foreign Exchange Remeasurement and Translation

During the first quarter of 2014, the Syndicate revised its foreign exchange accounting methodology from reporting its financial position and results using three functional currencies (GBP, USD and CAD) to one functional currency (USD). The USD was chosen as the single functional currency as the majority of the Syndicate’s insurance business has been and continues to be transacted in USD. This cumulative change in remeasurement has resulted in an immaterial correction of $10.0 million ($6.6 million after-tax) in Accumulated other comprehensive income (“AOCI”), on the Consolidated Balance Sheets, offset by a gain in Other income in the Consolidated Statements of Income.

Catastrophe Risk Management

Catastrophe Risk Management

We have exposure to losses caused by hurricanes, earthquakes, and other natural and man-made catastrophic events. The frequency and severity of catastrophic events is unpredictable. The extent of covered losses from a catastrophe is a function of both the total amount of insured exposure in an area affected by the event and the severity of the event. We had no material catastrophic events occur in the first quarter 2015.

Income Taxes

Income Taxes

The income tax provision has been computed based on our estimated annual effective tax rate. Our effective tax rate for the quarter differs from the federal tax rate of 35% principally because of tax-exempt investment income and dividends received deduction.

Current and Pending Accounting Pronouncements

Current and Pending Accounting Pronouncements

As of January 1, 2015, we did not adopt any new accounting pronouncements. In April 2015, the Financial Accounting Standards Board issued a new pronouncement, Accounting Standards Update 2015-03 – Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs, which will be effective for fiscal years beginning after December 15, 2015. The new pronouncement was issued to simplify presentation of debt issuance costs. We are assessing the future impact of this update to our Consolidated Financial Statements. There were no additional pending accounting pronouncements that are expected to have a significant impact on the consolidated financial statements upon adoption.

Fair Value Measurement

Note 4. Fair Value Measurement

The fair value of our financial instruments is determined based on the following fair value hierarchy:

Level 1 – Quoted prices for identical instruments in active markets. Examples are listed equity and fixed income securities traded on an exchange. U.S. Treasury securities are reported as Level 1 and are valued based on unadjusted quoted prices for identical assets in active markets that our Company can access.

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Examples are asset-backed and mortgage-backed securities that are similar to other asset-backed or mortgage-backed securities observed in the market. U.S. government agency securities are reported as Level 2 and are valued using yields and spreads that are observable in active markets.

Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. An example would be a private placement with minimal liquidity.

The following tables present, for each of the fair value hierarchy levels as defined by the accounting guidance for fair value measurements and described below, our Company’s fixed maturities and equity securities by asset class that are measured at fair value on a recurring basis, as well as the fair value of the 5.75% Senior notes due October 15, 2023 (the “Senior notes”) carried at amortized cost as of March 31, 2015 and December 31, 2014:

As of March 31, 2015 and December 31, 2014, our Company did not have a concentration of greater than 5% of invested assets in a single non-U.S. government-backed issuer.

As of March 31, 2015 and December 31, 2014, fixed maturities for which non-credit OTTI was previously recognized and included in AOCI are now in an unrealized gains position of $0.7 million.

The fair value of our Company’s investment portfolio may fluctuate significantly in response to various factors such as changes in interest rates, investment quality ratings, equity prices, foreign exchange rates and credit spreads. Our Company does not have the intent to sell nor is it more likely than not that it will have to sell fixed maturities in unrealized loss positions that are not other-than-temporarily impaired before recovery. For structured securities, default probability and severity assumptions differ based on property type, vintage and the stress of the collateral. Our Company does not intend to sell, and it is more likely than not that our Company will not be required to sell, these securities before the recovery of the amortized cost basis. For equity securities, our Company also considers our intent to hold securities as part of the process of evaluating whether a decline in fair value represents an other-than-temporary decline in value. Our Company may realize investment losses to the extent our liquidity needs require the disposition of fixed maturity securities in unfavorable interest rate, liquidity or credit spread environments. Significant changes in the factors our Company considers when evaluating investments for impairment losses could result in a significant change in impairment losses reported in the consolidated financial statements.

The contractual maturity dates for fixed maturities categorized by the number of years until maturity as of March 31, 2015 are shown in the following table:

	March 31, 2015
amounts in thousands	Fair Value		Amortized Cos t
Due in one year or less	$	55,121	$	59,300
Due after one year through five years		756,593		746,400
Due after five years through ten years		326,731		315,462
Due after ten years		361,018		346,208
Mortgage- and asset-backed securities		845,762		827,393
Total	$	2,345,225	$	2,294,763

Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Prepayment assumptions associated with the mortgage-backed and asset-backed securities are reviewed on a periodic basis. When changes in prepayment assumptions are deemed necessary as the result of actual prepayments differing from anticipated prepayments, securities are revalued based upon the new prepayment assumptions utilizing the retrospective accounting method. Due to the periodic repayment of principal, the mortgage-backed and asset-backed securities are estimated to have an effective maturity of approximately 4.5 years.

The following tables summarize all securities in a gross unrealized loss position as of March 31, 2015 and December 31, 2014, showing the aggregate fair value and gross unrealized loss by the length of time those securities have continuously been in a gross unrealized loss position:

At March 31, 2015, there were 147 fixed maturities in an unrealized loss position, and there were six equity securities in an unrealized loss position. In the above table, the gross unrealized loss for the greater than 12 months category consists primarily of agency and foreign government bonds primarily due to an unfavorable foreign exchange movement. At December 31, 2014, there were 259 fixed maturities in an unrealized loss position, and there were 15 equity securities in an unrealized loss position. The gross unrealized loss for the greater than 12 months category consists primarily of Treasury and agency bonds, due to an increase in interest rates and unfavorable foreign exchange movement.

As of March 31, 2015 and December 31, 2014, the largest unrealized loss by a non-government backed issuer in the investment portfolio was $0.4 million and $0.5 million, respectively.

Our Company analyzes impaired securities quarterly to determine if any are other-than-temporary. The above securities with unrealized losses have been determined to be temporarily impaired based on our evaluation.

For fixed maturities, when assessing whether the amortized cost basis of the security will be recovered, our Company compares the present value of cash flows expected to be collected in relation to the current book value. Any shortfalls of the present value of the cash flows expected to be collected to the amortized cost basis is considered the credit loss portion of OTTI losses and is recognized in earnings. All non-credit losses are recognized as changes in OTTI losses within AOCI.

To determine whether the unrealized loss on structured securities is other-than-temporary, our Company analyzes the projections provided by our investment managers with respect to an expected principal loss under a range of scenarios and utilizes the most likely outcomes. The analysis relies on actual collateral performance measures such as default rate, prepayment rate and loss severity. These assumptions are applied throughout the remaining term of the deal, incorporating the transaction structure and priority of payments, to generate loss adjusted cash flows. Results of the analysis will indicate whether the security is expected ultimately to incur a loss or whether there is a material impact on yield due to either a projected loss or a change in cash flow timing. A break-even default rate is also calculated. A comparison of the break-even default rate to the actual default rate provides an indication of the level of cushion or coverage to the first dollar principal loss. The analysis applies the stated assumptions throughout the remaining term of the transaction to forecast cash flows, which are then applied through the transaction structure to determine whether there is a loss to the security. For securities in which a tranche loss is present and the net present value of loss adjusted cash flows is less than book value, impairment is recognized. The output data also includes a number of additional metrics such as average life remaining, original and current credit support, over 60 day delinquency and security rating.

The significant inputs used to measure the amount of credit loss recognized in earnings were actual delinquency rates, default probability assumptions, severity assumptions and prepayment assumptions. Projected losses are a function of both loss severity and probability of default. Default probability and severity assumptions differ based on property type, vintage and the stress of the collateral. Our Company does not intend to sell, and it is more likely than not that it will not be required to sell, these securities before the recovery of the amortized cost basis.

For equity securities, in general, our Company focuses our attention on those securities with a fair value less than 80% of their cost for six or more consecutive months. If warranted as the result of conditions relating to a particular security, our Company will focus on a significant decline in fair value regardless of the time period involved. Factors considered in evaluating potential impairment include, but are not limited to, the current fair value as compared to cost of the security, the length of time the investment has been below cost and by how much the investment is below cost. If an equity security is deemed to be other-than-temporarily impaired, the cost is written down to fair value with the loss recognized in earnings.

Our Company’s ability to hold securities is supported by sufficient cash flow from our operations and from maturities within our investment portfolio in order to meet our claims payment and other disbursement obligations arising from our underwriting operations without selling such investments. With respect to securities where the decline in value is determined to be temporary and the security’s value is not written down, a subsequent decision may be made to sell that security and realize a loss. Subsequent decisions on security sales are made within the context of overall risk monitoring, changing information and market conditions.

Our Company did not have any credit related OTTI losses during the three months ended March 31, 2015 and 2014.

The following table summarizes the cumulative amounts related to our Company’s credit loss portion of the OTTI losses on fixed maturities for the three months ended March 31, 2015 and 2014. Our Company does not intend to sell, and it is more likely than not that it will not be required to sell, the securities prior to recovery of the amortized cost basis and for which the non-credit loss portion is included in AOCI.

Commitments and Contingencies

Note 7. Commitments and Contingencies

In 2013, the State of Connecticut (“the State”) awarded our Company up to $11.5 million ($8.0 million in loans and $3.5 million in grants) to move our corporate headquarters to Stamford, Connecticut. The loan is non-interest bearing, has a term of 10 years and is subject to forgiveness based on our compliance with certain conditions set forth in the agreement with the State. The amount of the loan to be received is dependent on our Company reaching certain milestones for creation of new jobs over a five-year period, and the funds are to be used to offset certain equipment purchases, facility costs, training of employees and other eligible project-related costs. Our Company completed the move to Stamford in September 2013 and received $7.5 million of the award, which is comprised of $6.0 million of the loan and $1.5 million of the grant for reaching the first job milestone. Earning of the grant and forgiveness of the loan is subject to certain conditions, including maintaining the required jobs for an extended period of time. As of March 31, 2015, the length of time commitment has not been met. However, our Company expects to meet all the conditions for the state to forgive the amount of the loan received to date, and accordingly, is recognizing the amount of loan and grants received over the period in which our Company recognizes the expenses for which the assistance is intended to compensate as a reduction of such expenses. Our Company recognized $0.2 million of the incentive for each of the three months ended March 31, 2015 and 2014, respectively. As of March 31, 2015 and December 31, 2014, our Company has deferred revenue of $5.9 million and $6.1 million, respectively, which is included in Other liabilities on the Consolidated Balance Sheets.

In the ordinary course of conducting business, our Company’s subsidiaries are involved in various legal proceedings, either indirectly as insurers for parties or directly as defendants. Most of these proceedings consist of claims litigation involving the Company’s subsidiaries as either: (a) liability insurers defending or providing indemnity for third party claims brought against insureds or (b) insurers defending first party coverage claims brought against them. Our Company accounts for such activity through the establishment of unpaid loss and LAE reserves. Our Company’s management believes that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and cost of defense, will not be material to our Company’s Consolidated Balance Sheets, Consolidated Statements of Income or Consolidated Statements of Cash Flows.

Our Company’s subsidiaries are also from time to time involved with other legal actions, some of which assert claims for substantial amounts. These actions include claims asserting extra contractual obligations, such as claims involving allegations of bad faith in the handling of claims or the underwriting of policies. In general, our Company believes it has valid defenses to these cases. Our Company’s management expects that the ultimate liability, if any, with respect to future extra-contractual matters will not be material to our Consolidated Balance Sheets, Consolidated Statements of Income or Consolidated Statements of Cash Flows. Nonetheless, given the large or indeterminate amounts sought in certain of these matters, and the inherent unpredictability of litigation, an adverse outcome in such matters could, from time to time, have a material adverse outcome on our Company’s Consolidated Statements of Income or Consolidated Statements of Cash Flows in a particular fiscal quarter or year.

Ceded Reinsurance

Note 5. Ceded Reinsurance

As of March 31, 2015, the credit quality distribution of our Company’s reinsurance recoverables of $1.1 billion for ceded paid losses, ceded unpaid losses and LAE, and ceded unearned premiums based on insurer financial strength ratings from A.M. Best or S&P was not significantly different from the credit quality distribution as of December 31, 2014.

Our allowance for uncollectible reinsurance was $8.2 million and $11.3 million as of March 31, 2015 and December 31, 2014, respectively. The reduction in our allowance for uncollectible reinsurance was the result of payments of outstanding balances from one of our large reinsurers.

As of March 31, 2015, our 20 largest reinsurers measured by the amount of Reinsurance recoverable for ceded losses and LAE and ceded unearned premium, together with the Reinsurance recoverable and collateral, were not significantly different from December 31, 2014.

Credit Facilities

On November 6, 2014, NUAL entered into a credit facility for $8.0 million Australian Dollars with Barclays Bank PLC to fund its participation in the Syndicate. The facility is used to fund Australian underwriting obligations for the 2015 and prior underwriting years. The facility contains customary covenants for facilities of this type, including a restriction on future encumbrances that are outside the ordinary course of business, and a requirement to maintain at least £75 million of Funds at Lloyd’s. Interest is payable on the facility at a rate of 2% per annum above a floating rate tied to the average mid-rate for Australian bills of exchange administered by the Australian Financial Markets Association. The facility may be cancelled by either party after providing written notice. As of March 31, 2015, our Company was in compliance with all covenants.

On November 24, 2014, our Company entered into a $175 million credit facility agreement with ING Bank N.V., London Branch, individually and as Administrative Agent, and a syndicate of lenders. The new credit facility amended and restated a $165 million letter of credit facility entered into by the parties on November 22, 2012. The credit facility, which is denominated in U.S. dollars, is utilized to fund our participation in the Syndicate by posting Funds at Lloyd’s through letters of credit for the 2015 and 2016 underwriting years, as well as open prior years. The letters of credit issued under the facility can be denominated in British pounds and their aggregate face amount will fluctuate based on exchange rates. If any letters of credit remain outstanding under the facility after December 31, 2016, our Company would be required to post additional collateral to secure the remaining letters of credit. As of March 31, 2015, letters of credit with an aggregate face amount of $145.1 million were outstanding under the credit facility and our Company had $1.0 million of cash collateral posted.

This credit facility contains customary covenants for facilities of this type, including restrictions on indebtedness and liens, limitations on mergers, dividends and the sale of assets, and requirements as to maintaining certain consolidated tangible net worth, statutory surplus and other financial ratios. The credit facility also provides for customary events of default, including failure to pay principal, interest or fees when due, failure to comply with covenants, any representation or warranty made by our Company being false in any material respect, default under certain other indebtedness, certain insolvency or receivership events affecting our Company and its subsidiaries, the occurrence of certain material judgments, or a change in control of our Company. The letter of credit facility is secured by a pledge of the stock of certain insurance subsidiaries of our Company. To the extent the aggregate face amount issued under the credit facility exceeds the commitment amount, our Company is required to post collateral with the lead bank of the syndicate of lenders.

The applicable fee rate payable under the credit facility is based on a tiered schedule that is based on our Company’s then-current financial strength ratings issued by S&P and A.M. Best and the amount of our Company’s own collateral utilized to fund its participation in the Syndicate.

Note 8. Stock Options, Stock Grants, SARs and ESPP

Stock-based compensation granted under the Company’s stock plans is expensed in tranches over the vesting period. Options and non-performance based grants generally vest equally over a three or four-year period and the options have a maximum term of ten years. Pursuant to the provisions of the Second Amended and Restated 2005 Stock Incentive Plan (“the Plan”), shares that are subject to an award and are forfeited or otherwise terminate without the delivery of the full number of shares may, to the extent of such forfeiture or termination, again be available for grant under the Plan. The Compensation Committee has adopted a policy that shares that are forfeited to satisfy the withholding tax obligations of a grantee, and which have not otherwise been issued or outstanding, will, pursuant to this provision, again be available for grant under the Plan. This policy has been applied effective January 1, 2010.

Restricted stock units and performance units are granted at the market closing price on the grant date. On February 10, 2015, we granted 4,658 restricted stock units and on March 5, 2015, we granted 185,050 performance units to employees and officers with a grant date fair market value of $77.31 and $74.49, respectively. Each performance unit and restricted stock unit represents a contingent right to receive of one share of common stock as of the vesting date.

Segment Information

Note 2. Segment Information

During the first quarter of 2015, we realigned our reporting segments from Insurance Companies, Lloyd’s Operations and Corporate to U.S. Insurance, International Insurance (“Int’l Insurance”), Global Reinsurance (“GlobalRe”) and Corporate. The new segment presentation reflects an increase in the level of importance that the Chief Operating Decision Maker now places on the results of the underlying operating segments when aggregated and reported in alignment with the products and services offered to the marketplace versus when aggregated and reported in alignment with our legal entity structure. Over the past few years, we have been monitoring the growth and stability of our reinsurance business and in 2015 determined that reinsurance has become a stable and significant component of our Company. We are also increasing our focus on additional international insurance markets by establishing underwriting offices in Continental Europe. The offices were fully operational during our January renewal season. We considered these changes in conjunction with operating and reportable segments.

Our previously reported segments were consistent with our legal entity structure; however, our new reporting segments are now primarily reflective of where our business is written. We reclassified our international business from our previously reported Lloyd’s Operations segment to the Int’l Insurance segment. We also reclassified our non-Lloyd’s business written internationally (primarily business written by the U.K. Branch) into this segment and have excluded Assumed Reinsurance. Our new GlobalRe segment was previously reported within our U.S. Insurance and Lloyd’s Operations segments as Assumed Reinsurance. Our U.S. Insurance segment now excludes the U.K. Branch and Assumed Reinsurance. Our Corporate segment now includes investment income (loss), interest income (loss), foreign exchange gain (loss) and income tax benefit (expense), which are not allocated to the U.S. Insurance, Int’l Insurance and GlobalRe segments (together “underwriting segments”). We do not allocate assets under the new reporting segments, as it is impracticable to do so.

As noted above, we classify our business into three underwriting segments (U.S. Insurance, Int’l Insurance and GlobalRe) and a Corporate Segment. Both the U.S. Insurance and Int’l Insurance reporting segments are each comprised of three operating segments: Marine, Professional Liability and P&C. These operating segments have been aggregated into the aforementioned reporting segments based upon the criteria specified in Accounting Standards Codification 280, Segment Reporting. Consistent with the guidance, these operating segments; (a) engage in business activities from which they may earn revenues and incur expenses, (b) are regularly reviewed by our management to assess the performance of the segments and make decisions about resources to be allocated to the segments and (c) have discrete financial information.

We evaluate the performance of each of the underwriting segments based on underwriting results. Underwriting results are measured based on underwriting profit or loss and the related combined ratio, which are both non-GAAP measures of underwriting profitability. Underwriting profit or loss is calculated from net earned premiums less the sum of net losses and loss adjustment expenses (“LAE”), commission expenses, other operating expenses, and other underwriting income (expense). The combined ratio is derived by dividing the sum of net loss and LAE, commission expenses, other operating expenses and other underwriting income (expense) by net earned premiums. A combined ratio of less than 100% indicates an underwriting profit and greater than 100% indicates an underwriting loss. Our underwriting performance is evaluated separately from the rest of our operations. The performance of our investment portfolios, our liquidity and capital resource needs, our foreign currency exposure and our tax planning strategies are evaluated on a consolidated basis within our Corporate reporting segment.

The accounting policies used to prepare the segment reporting data for our reporting segments are the same as those described in Note 1 and Note 3 of our Annual Report on Form 10-K for the year ended December 31, 2014. In addition, 2014 data presented in this Quarterly Report has been recast to align with the new segment reporting described above.

Financial data by segment for the three months ended March 31, 2015 and 2014 were as follows:
