THE NAVIGATORS GROUP, INC. AND SUBSIDIARIES

Notes to Interim Consolidated Financial Statements (Unaudited)

Note 1. Organization and Summary of Significant Accounting Policies

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 & Omissions (“E&O”) 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.

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.

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 (loss) in the Consolidated Statements of Income.

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 2015, the Financial Accounting Standards Board issued the following new pronouncements that may have an impact on our Company and we are assessing the future impact of these updates to our Consolidated Financial Statements:

• 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.

8

• Accounting Standards Update 2015-05 – Intangibles – Goodwill and Other – Internal Use Software (Subtopic 350-40) Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, which will be effective for fiscal years beginning after December 15, 2015. The new pronouncement was issued to provide guidance to customers about whether a cloud computing arrangement includes a software license.

• Accounting Standards Update 2015-07 – Fair Value Measurement – (Topic 820) Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or its equivalent) (a consensus of the Emerging Issues Task Force), which will be effective for fiscal years beginning after December 15, 2015. The new pronouncement was issued to ensure that all investments categorized in the fair value hierarchy are classified using a consistent approach.

• Accounting Standards Update 2015-09 – Financial Services Insurance – (Topic 944) Disclosures about Short-Duration Contracts, effective for annual periods beginning after December 15, 2015. The new pronouncement was issued to (1) increase the usefulness of the information about a reporting entity’s insurance liabilities, including the nature, amount, timing, and uncertainty of cash flows related to those liabilities and the effect of those cash flows on the Statements of Comprehensive Income and (2) improve comparability between reporting entities, regardless of the type of entity issuing the contract.

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), Other income (loss) primarily consisting of foreign exchange gain (loss) and Income tax (expense) benefit, 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, P&C and Professional Liability.

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 losses 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 segment.

The accounting policies used to prepare the segment reporting data for our reportable 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 June 30, 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 June 30, 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 $0.6 million and $0.7 million, respectively.

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

13

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 June 30, 2015 are shown in the following table:

	As of June 30, 2015
amounts in thousands	Fair Value		Amortized Cost
Due in one year or less	$	64,435	$	67,319
Due after one year through five years		721,735		713,956
Due after five years through ten years		350,030		345,148
Due after ten years		389,728		385,292
Mortgage- and asset-backed securities		788,009		779,422
Total	$	2,313,937	$	2,291,137

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 4.7 years.

As of June 30, 2015, there were 345 fixed maturities and 49 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 principally due to an unfavorable foreign exchange movement. As of December 31, 2014, there were 259 fixed maturities and 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 June 30, 2015 and December 31, 2014, the largest unrealized loss by a non-government backed issuer in the investment portfolio was $0.9 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

15

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, severity 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 payments 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 had one credit related OTTI loss of $0.4 million in the equity portfolio during the three and six months ended June 30, 2015. The Company did not have any credit related OTTI losses during the three and six months ended June 30, 2014.

As of June 30, 2015 and 2014, the cumulative amounts related to our Company’s credit loss portion of the OTTI losses on fixed maturities were $2.4 million and $5.2 million, respectively. There was no activity for the three and six months ended June 30, 2015 and 2014 related to these amounts. 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.

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 June 30, 2015 and December 31, 2014:

Our Company did not have any significant transfers between the Level 1 and Level 2 classifications for the three and six months ended June 30, 2015 and 2014.

As of June 30, 2015, our Company did not have any Level 3 assets. During 2014, one security was transferred from Level 3 to Level 2 as 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 June 30, 2015, the credit quality distribution of our Company’s Reinsurance recoverable of $1.2 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 June 30, 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 June 30, 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.

Note 6. 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 June 30, 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 $0.3 million and $0.5 million of the incentive for the three and six months ended June 30, 2015, respectively. As of June 30, 2015 and December 31, 2014, our Company has deferred revenue of $5.6 million and $6.1 million, respectively, which is included in Other liabilities on the Consolidated Balance Sheets.

18

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 losses 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 7. 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. For the six months ended June 30, 2015 we granted 197,708 stock incentive units at a grant price between $73.62 and $78.86. Each performance unit and restricted stock unit represents a contingent right to receive one share of common stock as of the vesting date. Such common stock may be subject to forfeiture for the payment of any required tax withholding.

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

FORWARD-LOOKING STATEMENTS

Some of the statements in this Quarterly Report on Form 10-Q are “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact included in or incorporated by reference in this Quarterly Report are forward-looking statements. Whenever used in this report, the words “estimate,” “expect,” “believe,” “may,” “will,” “intend,” “continue” or similar expressions or their negative are intended to identify such forward-looking statements. Forward-looking statements are derived from information that we currently have and assumptions that we make, and are subject to a number of risks and uncertainties, including those described in the “Risk Factors” section of our 2014 Annual Report on Form 10-K. We operate in a very competitive environment, with new risks emerging from time to time. We cannot assure you that anticipated results will be achieved, since actual results may differ materially because of both known and unknown risks and uncertainties which we face.

In light of these risks, uncertainties and assumptions, any forward-looking events discussed in this Form 10-Q may not occur, and we undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. You are cautioned not to place undue reliance on any forward-looking statements, which speak only as of their respective dates.

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 (loss) represents one measure of the pretax profitability of our insurance operations and is derived by subtracting Net losses and LAE, Commission expenses and Other operating expenses from Net earned premiums. This information is available in total and by segment in Note 2 – Segment Information to the Interim Consolidated Financial Statements as of June 30, 2015. The nearest comparable GAAP measure is Income before income taxes which, in addition to Net underwriting profit (loss), includes Net investment income, OTTI, Net realized gains (losses) on investments, Interest expense and Other income (loss).

Combined Ratio

The Combined ratio is a common insurance industry measure of profitability for any underwriting operation and is calculated in two components. First, the loss ratio is Net losses and LAE divided by Net earned premiums. The second component, the expense ratio, reflects the sum of Commission expenses and insurance operating expenses, divided by Net earned premiums. All items included in these components of the Combined ratio are presented in our GAAP Consolidated 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 percent implies that for every $100 of premium we earn, we record $15 of Underwriting profit.

Net Losses and LAE Reserves

Net losses and LAE reserves, 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 both known claims and IBNR that we expect to recover from reinsurers. The net of these two items is generally referred to as net unpaid losses 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 the end of the interim period.

20

Net Operating Earnings

Net operating earnings is calculated as Net income before after-tax Net realized gains (losses), OTTI losses recognized in earnings, and after-tax realized and unrealized 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 USD).

Overview

The discussion and analysis of our financial condition and results of operations contained herein should be read in conjunction with our 2014 Annual Report on Form 10-K in its entirety as well as the statements under “Forward-Looking Statements” and the Interim Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q for a complete description of events, trends, uncertainties, risks and critical accounting estimates affecting us.

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 E&O divisions. Beginning in 2010, we added reinsurance products through our Assumed Reinsurance division.

Financial Highlights

• Net income was $19.2 million and $45.1 million for the three and six months ended June 30, 2015, an increase of 13.8% and 0.6% compared to the same periods in the prior year, respectively.

• Earnings per diluted share were $1.30 and $3.06 for the three and six months ended June 30, 2015, an increase of 11.1% and a decrease of 1.6% compared to the same periods in the prior year, respectively.

• Underwriting profit was $16.1 million and $34.3 million for the three and six months ended June 30, 2015, an increase of 47.0% and 20.5% compared to the same periods in the prior year, respectively.

• Net investment income was $16.6 million and $32.8 million for the three and six months ended June 30, 2015, an increase of 6.1% and 1.8% compared to the same periods in the prior year, respectively.

• Net cash provided by operations was $2.7 million as of June 30, 2015, a decrease of $75.5 million compared to the same period in the prior year.

• Annualized return on equity was 8.8% as of June 30, 2015, a decrease of 1.1% compared to the same period in the prior year.

• Book value was $1.1 billion as of June 30, 2015, an increase of 2.6% compared to December 31, 2014.

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, Commission expenses 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 Interim Consolidated Financial Statements, included herein.

Gross Written Premiums

Gross written premiums increased $30.7 million for the three months ended June 30, 2015 compared to the same period in 2014 primarily due to growth in our U.S. P&C operating segment specifically in our Excess Casualty and Primary Casualty

22

divisions, as well as growth in our GlobalRe segment, all related to strong market conditions and increased underwriting opportunities. Gross written premiums increased $4.3 million for the six months ended June 30, 2015 compared to the same period in 2014 primarily due to the same factors as discussed above, offset by the non-renewal of a large GlobalRe treaty in the first quarter of 2015.

Average renewal premium rates for the three and six months ended June 30, 2015 decreased by 3.9% and 3.1%, respectively, compared to the same periods in 2014.

Ceded Written Premiums

Ceded written premiums increased $4.3 million and $0.9 million, for the three and six months ended June 30, 2015, respectively, compared to the same periods in 2014 primarily due to reinsurance reinstatement premium (“RRP”), changes in our mix of business written and certain changes in our reinsurance programs.

For the three months ended June 30, 2015, we recorded $1.2 million of reversals of previously booked RRP accruals, compared to $6.6 million of additional accruals reported in the three months ended June 30, 2014. For the six months ended June 30, 2015, we recorded $0.6 million of reversals of previously booked RRP accruals, compared to $7.6 million of additional accruals reported in the six months ended June 30, 2014. Prior year-to-date RRPs included an Int’l Marine Liability loss, which involved the sinking of a vessel in South Korean waters of $3.9 million, as well as other unfavorable RRP adjustments of $3.6 million, including $1.3 million related to Costa Concordia.

Net Earned Premiums

Net earned premiums increased $11.2 million for the three months ended June 30, 2015 compared to the same period in 2014. The increase is primarily driven by strong new business production in our U.S. P&C operating segment. In addition, in second quarter 2014 the Net earned premiums included fully earned RRPs, which had a favorable year over year effect. Net earned premiums increased $22.1 million for the six months ended June 30, 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, prior year growth in our U.S. Insurance reporting segment and the prior year RRPs described above.

Net Losses and LAE

The following table presents the impact of RRPs and reserve development on our Net losses and LAE ratio for the three and six months ended June 30, 2015 and 2014 (note: accident year is abbreviated “AY”):

	Three months ended June 30,						Point
	2015			2014			Change
Net losses and LAE ratio, reported		58.6	%		60.7	%		-2.1
RRPs		0.4	%		-1.6	%		2.0
Current AY release/(development)		-2.1	%		-6.2	%		4.1
Prior AY release/(strengthening)		3.0	%		8.6	%		-5.6
Net losses and LAE ratio, adjusted		59.9	%		61.5	%		-1.6
	Six months ended June 30,						Point
	2015			2014			Change
Net losses and LAE ratio, reported		56.9	%		60.3	%		-3.4
RRPs		0.1	%		-0.7	%		0.8
Current AY release/(development)		-1.6	%		-3.2	%		1.6
Prior AY release/(strengthening)		4.2	%		4.5	%		-0.3
Net losses and LAE ratio, adjusted		59.6	%		60.9	%		-1.3

For the three and six months ended June 30, 2015, we recorded $7.3 million and $19.9 million of prior AY reserve releases, respectively, as compared to $20.5 million of releases for both periods in 2014. The releases in the first six months of 2015 are related to favorable loss emergence as well as a reduction to the provision for uncollectible reinsurance due to payments of outstanding balances from one of our large reinsurers.

Commission Expenses

Commissions 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. Commission expenses 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 and six months ended June 30, 2015 was 13.0% and 13.5%, respectively, as compared to 13.9% and 12.7%, respectively, for the comparable periods during 2014. The change in the Commission expense ratio for the three and six months ended June 30, 2015 compared to the same periods in 2014 is attributable to the changes in the mix of business, changes in our reinsurance programs and to a lesser extent higher profit commission accruals for certain products.

Other Operating Expenses

Other operating expenses were $52.8 million and $107.7 million for the three and six months ended June 30, 2015, respectively, compared to $48.0 million and $95.1 million for the same periods in 2014, respectively. The increase for the three and six months ended June 30, 2015 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 financial results over the corresponding prior period.

Net Investment Income

Our Net investment income was derived from the following sources:

	Three Months Ended June 30,						Six Months Ended June 30,						% Change
amounts in thousands	2015			2014			2015			2014			QTD			YTD

Short-term investments		146			242			330			459			-39.7	%		-28.1	%
Total investment income	$	17,278		$	16,401		$	34,478		$	33,805			5.3	%		2.0	%
Investment expenses		(683	)		(753	)		(1,630	)		(1,547	)		-9.3	%		5.4	%
Net investment income	$	16,595		$	15,648		$	32,848		$	32,258			6.1	%		1.8	%

The increase in total investment income for the three months ended June 30, 2015 as compared to the same period in the prior year was primarily due to growth of invested assets, partially offset by a reduction in interest income due to falling investment yields. The annualized pre-tax yield, excluding Net realized gains and losses and OTTI losses recognized in earnings, for the three months ended June 30, 2015 and 2014, was 2.4% and 2.5%, respectively.

The increase in total investment income for the six months ended June 30, 2015 as compared to the prior year was primarily due to growth of invested assets, partially offset by a one-time special dividend of $1.6 million in the prior year from our equity portfolio and a reduction of investment income due to falling investment yields. The annualized pre-tax yield, excluding Net realized gains and losses and OTTI losses recognized in earnings, was 2.4% and 2.6% for the six months ended June 30, 2015 and 2014, respectively.

As part of our overall investment strategy, we seek to build a tax efficient investment portfolio. During 2015, the tax-exempt portion of our investment portfolio increased by $8.1 million to approximately 21.8% of the fixed maturities investment portfolio. The tax equivalent yields for the six months ended June 30, 2015 and 2014 on a consolidated basis were 2.5% and 2.8%, respectively.

OTTI Losses Recognized in Earnings

Our Company had one credit related OTTI loss of $0.4 million from our equity portfolio during the three and six months ended June 30, 2015. The Company did not have any credit related OTTI losses during the three and six months ended June 30, 2014.

Net Realized Gains and Losses

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

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 $4.3 million and $9.9 million for the three and six months ended June 30, 2015, respectively, are primarily due to the sale of equity securities. Net realized gains of $4.5 million and $5.3 million for the three and six months ended June 30, 2014, respectively, are primarily due to the sale of corporate bonds and equity securities.

Interest Expense

Interest expense was $3.9 million and $7.7 million for the three and six months ended June 30, 2015, respectively, and $4.3 million and $8.2 million for the three and six months ended June 30, 2014, respectively, relating 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 (Loss)

Other income (loss) for the three and six months ended June 30, 2015 was a $4.4 million loss and a $2.1 million loss, respectively, as compared to Other income (loss) of $1.7 million loss and $8.7 million income for the same periods in the prior year, respectively. Other income (loss) primarily consists of realized and unrealized foreign exchange gains and losses. The current quarter and six month foreign exchange losses are mostly driven by the weakening of the USD against the GBP. 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, in the Notes to Interim Consolidated Financial Statements, included herein for additional information regarding the foreign currency adjustment.

Income Taxes

We recorded an Effective tax rate of 32.4% for the three and six months ended June 30, 2015, compared to 32.2% and 32.3%, respectively, for the same periods 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 due to tax-exempt investment income and dividends received deduction.

Book Value and Book Value Per Share

As of June 30, 2015, our book value was $1.1 billion and our book value per share was $73.18, increasing 1.7% from $71.93 per share as of December 31, 2014, mostly driven by $45.1 million of Net income, partially offset by Total other comprehensive loss of $21.9 million for the six months ended June 30, 2015.

Gross Written Premiums

Gross written premiums increased $33.3 million for the three months ended June 30, 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 24.1%. This increase was specifically driven by our Primary Casualty, Excess Casualty and Environmental divisions, which increased 27.1%, 23.3% and 11.5%, respectively.

Gross written premiums increased $34.3 million for the six months ended June 30, 2015 compared to the same period in 2014 due to the impacts discussed above for the quarter, offset by a decrease in our U.S. Professional Liability operating segment 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 our U.S. Insurance reporting segment for the three and six months ended June 30, 2015 decreased 1.1% and 0.9%, respectively. For the three months ended June 30, 2015, the decrease was primarily driven by a decline of 1.6% and 1.1% in our U.S. Professional Liability and U.S. P&C operating segments, respectively. For the six months ended June 30, 2015, the decrease was primarily driven by a decline of 2.7% and 0.8% in our U.S. Professional Liability and U.S. P&C operating segments, respectively.

Ceded Written Premiums

Ceded written premiums increased $18.9 million and $22.5 million for the three and six months ended June 30, 2015, respectively, compared to the same periods in 2014. The increase for both the three and six months ended June 30, 2015 was primarily due to two new proportional reinsurance programs implemented in the first quarter of 2015, covering products within our U.S Marine operating segment, offset by a decrease in excess-of-loss reinsurance also within our U.S. Marine operating segment. Additionally, contributing to the increase was a new reinsurance program implemented in the fourth quarter of 2014, which includes proportional and excess-of-loss coverage on various products within our E&O division. The increase in our U.S. Marine operating segment is primarily due to RRPs of $1.0 million for Rena and $0.7 million for Costa Concordia in the prior year, with RRP accrual reversals in the current quarter, which resulted in a positive year over year effect.

Net Earned Premiums

Net earned premiums increased $12.0 million and $27.9 million for the three and six months ended June 30, 2015, respectively, compared to the same periods in 2014. The increase was primarily driven by continued growth in our Excess Casualty and Primary Casualty divisions of our U.S. P&C operating segment compounded by reductions to reinsurance programs in our Excess Casualty division. Additionally, prior year Net earned premiums included fully earned RRPs of $1.4 million, which had a favorable year over year effect. The increase in Net earned premiums was partially offset by the effect of new ceded reinsurance programs in our U.S. Marine and U.S. Professional Liability operating segments, as described above.

Net Losses and LAE

The Net losses and LAE reserves as of June 30, 2015 and December 31, 2014 are as follows:

Our U.S. Insurance reporting segment recorded $7.8 million of net prior AY reserve releases for the three months ended June 30, 2015, primarily driven by $4.3 million and $3.6 million of reserve releases from our U.S. Professional Liability and U.S. Marine operating segments, respectively, due to a decline in large loss activity.

Our U.S. Insurance reporting segment recorded $14.2 million of net prior AY reserve releases for the six months ended June 30, 2015, primarily driven by $8.0 million and $5.2 million of reserve releases from our U.S. Marine and U.S. Professional Liability operating segments, respectively, due to a decline in large loss activity as well as collections of recoverables previously written off and to a lesser extent, a $1.5 million release of provision for uncollectible reinsurance due to payments of outstanding balances from one of our large reinsurers.

The changes in Net losses and LAE ratio, as adjusted, are primarily due to the mix of business earned.

Commission Expenses

The Commission expense ratio for the three months ended June 30, 2015 decreased 1.7 points as compared to the same period in 2014, primarily driven by changes in the proportional reinsurance programs across various product lines with increased cessions in our U.S. Marine and U.S. Professional Liability operating segments. Additionally, our Commission expenses benefitted from increased profit commissions.

The Commission expense ratio for the six months ended June 30, 2015 increased 0.4 points compared to the same period in 2014. The increase was primarily driven by less ceded proportional reinsurance within our Excess Casualty division of our U.S. P&C operating segment, partially offset by the favorable effects noted above for the second quarter of 2015.

Other Operating Expenses

For the three and six months ended June 30, 2015, Other operating expenses increased $2.5 million and $8.2 million, respectively, compared to the same periods in 2014, primarily driven by continued investment in our underwriting teams and support staff and an increase in incentive compensation driven by improved financial results over the corresponding prior periods.

Gross Written Premiums

Gross written premiums decreased $11.9 million for the three months ended June 30, 2015 compared to the same period in 2014, mostly driven by a decline in our Int’l P&C operating segment of $9.7 million, which was due to lower renewal premiums and rate reductions in our Int’l Energy & Engineering division. In addition, we had a decline in our Int’l Marine operating segment of $6.1 million, related primarily to lower renewal premiums and rate reductions in our Cargo, Marine Liability and Energy Liability divisions. This decline has been substantially offset by a $3.8 million growth in our Int’l Professional Liability operating segment, predominately due to operations in our new European offices, new business written and increased renewal premiums as we have increased line sizes across several client accounts.

Gross written premiums decreased $8.7 million for the six months ended June 30, 2015 compared to the same period in 2014. The decrease in Gross written premiums was primarily driven by a decline in our Int’l P&C operating segment of $19.0 million as discussed above, offset by growth in the Int’l Professional Liability operating segment of $11.0 million, of which $2.4 million relates to our new product line Warranties and Indemnities, and $2.7 million which relates to premium generated by the new European offices.

Average renewal premium rates for our Int’l Insurance segment for the three and six months ended June 30, 2015 decreased 8.6% and 5.7%, respectively. The decline for the three months was driven by decreases of 12.8%, 7.2% and 5.7% in our Int’l P&C, Int’l Professional Liability and Int’l Marine operating segments, respectively. The decline for the six months is driven by decreases of 9.8%, 5.7% and 2.9% in our Int’l P&C, Int’l Professional Liability and Int’l Marine operating segments, respectively.

Ceded Written Premiums

Ceded written premiums decreased $14.7 million and $23.1 million for the three and six months ended June 30, 2015, respectively, compared to the same periods in 2014. The decreases for both the three and six months were primarily due to decreases in our proportional reinsurance program within each of our operating segments as well as current period reductions to RRP accruals compared with higher RRPs in our Int’l Marine operating segment in the prior year, primarily due to a loss which involved the sinking of a vessel in South Korean waters of $3.9 million, $0.8 million for Rena and $0.6 million for Costa Concordia, which resulted in a positive year over year effect.

Net Earned Premiums

Net earned premiums increased $3.5 million for the three months ended June 30, 2015 as compared to the same period in 2014. This was driven by increases in our Int’l Marine and Int’l Professional Liability operating segments of $5.9 million and $3.8 million, respectively, offset by a decrease in our Int’l P&C operating segment of $6.3 million. The increase in our Int’l Professional Liability operating segment was driven by continued growth, specifically the E&O division and Warranties and Indemnities product line. Prior year Net earned premiums included fully earned RRPs of $5.1 million, which had a favorable year over year effect.

Net earned premiums increased $7.0 million for the six months ended June 30, 2015 as compared to the same period in 2014. This increase was due to fully earned RRPs in the prior year, continued growth in our Int’l Marine and Int’l Professional Liability operating segments offset by the decline in our Int’l P&C operating segment, as discussed above.

The Net losses and LAE reserves as of June 30, 2015 and December 31, 2014 are as follows:

For the three months ended June 30, 2015, our Int’l Insurance reporting segment recorded $0.6 million of net prior AY reserve strengthening primarily driven by our Int’l Marine operating segment, offset by net prior AY reserve releases of $0.4 million in our Int’l P&C operating segment.

For the six months ended June 30, 2015, our Int’l Insurance reporting segment recorded $5.6 million of net prior AY reserve releases primarily driven by $2.5 million and $2.3 million of net reserve releases in our Int’l Marine and Int’l P&C operating segments, respectively, in connection with favorable loss emergence and, to a lesser extent, a $1.6 million release of provision for uncollectible reinsurance due to payments of outstanding balances from one of our large reinsurers.

The changes in Net losses and LAE ratio, as adjusted, are primarily due to the mix of business earned.

Commission Expenses

The commission expense ratio for the three and six months ended June 30, 2015 decreased 0.6 points and increased 1.3 points, respectively, as compared to the same periods in 2014, primarily driven by changes in our mix of business, changes in our proportional reinsurance programs, and to a lesser extent, higher profit commissions for certain products.

Other Operating Expenses

For the three and six months ended June 30, 2015, Other operating expenses increased $1.9 million and $3.9 million, respectively, as compared to the same periods in 2014 due to investment in new underwriting initiatives in continental Europe including new underwriting offices in Rotterdam, Milan and Paris, and continued investment in new underwriting teams and support staff, offset by favorable foreign exchange rates.

Gross Written Premiums

Gross written premiums increased $9.3 million for the three months ended June 30, 2015 compared to the same period in 2014, primarily due to the new business opportunities within our Accident & Health and Property divisions.

Gross written premiums decreased $21.2 million for the six months ended June 30, 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 our Latin America (“LatAm”) and Marine divisions, offset by year over year increases in our Accident & Health, Professional Liability and Property divisions, due to new business opportunities.

Ceded Written Premiums

Ceded written premiums increased $0.1 million and $1.4 million for the three and six months ended June 30, 2015, respectively, compared to the same periods in 2014, primarily due to two additional retrocessional treaties written in 2015 for our LatAm surety product line as well as an increase in the retrocessional treaties, which includes our Property division.

Net Earned Premiums

Net earned premiums decreased $4.3 million and $12.8 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. These decreases were primarily due to the non-renewal of the crop quota share treaty noted above and less RRPs assumed than in prior year, partially offset by growth in our Professional Liability, LatAm and Property divisions.

Net Losses and LAE

The Net losses and LAE reserves as of June 30, 2015 and December 31, 2014 are as follows:

	GlobalRe
	As of
amounts in thousands	June 30, 2015		December 31, 2014		% Change
Case Reserves	$	26,964	$	31,108		-13.3	%
IBNR Reserves		101,723		90,580		12.3	%
Total	$	128,687	$	121,688		5.8	%

The following tables present the impact of RRPs and reserve development on our Net losses and LAE ratio for the three and six months ended June 30, 2015 and 2014:

	GlobalRe

Prior AY release/(strengthening)		0.0	%		-2.8	%		2.8
Net losses and LAE ratio, adjusted		59.5	%		65.6	%		-6.1

The favorable variances in adjusted Net losses and LAE ratio for the three and six months ended June 30, 2015 compared to the same periods in 2014 were primarily driven by mix of business earned, including the non-renewal of the crop quota share treaty which had carried a higher loss ratio.

35

Commission Expenses

The Commission expense ratio increased 0.9 points and 1.6 points for the three and six months ended June 30, 2015 compared to the same periods in 2014, resulting from an increase in Accident & Health and LatAm divisions profit commissions payable as well as the non-renewal of a significant multiple peril crop quota share treaty, which carried a lower commission rate.

Other Operating Expenses

Other operating expenses increased $0.3 million and $0.5 million for the three and six months ended June 30, 2015, respectively, compared to the same periods 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 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 and Liquidity

Capital Resources

Our capital resources consist of funds deployed or available to be deployed to support our business operations. As of June 30, 2015 and December 31, 2014, our capital resources were as follows:

	As of
amounts in thousands	June 30, 2015			December 31, 2014
Senior notes	$	263,509		$	263,440
Stockholders’ equity		1,053,629			1,027,224
Total capitalization	$	1,317,138		$	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 our Parent Company or dividends from its subsidiaries.

Navigators Insurance Company may pay dividends to our Parent Company out of its statutory earned surplus pursuant to statutory restrictions imposed under the New York insurance law. As of June 30, 2015, the maximum amount available for the payment of dividends by Navigators Insurance Company in 2015 without prior regulatory approval is $89.9 million.

Navigators Corporate Underwriters, Ltd., our wholly-owned corporate member at Lloyd’s, may pay dividends to our Parent Company up to the extent of available profits that have been distributed from the Syndicate. As of June 30, 2015, that amount was $12.6 million (£8.0 million).

Senior Notes and Credit Facility

On October 4, 2013, we completed a public debt offering of $265.0 million of the 5.75% Senior notes and received net proceeds of $263 million. The effective interest rate related to the net proceeds received from the 5.75% Senior notes is approximately 5.86%. Interest is payable on the 5.75% Senior notes each April 15 and October 15.

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 (“UWYs”). 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 June 30, 2015, our Company was in compliance with all covenants.

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. The new credit facility amended and restated a $165.0 million letter of credit facility entered into by the parties on November 22, 2012. The credit facility, which is denominated in USD, is utilized to fund our participation in the Syndicate by posting Funds at Lloyd’s through letters of credit for the 2015 and 2016 UWYs, as well as open prior years. The letters of credit issued under the facility can be denominated in GBP and their aggregate face amount will

36

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 June 30, 2015, letters of credit with an aggregate face amount of $149.6 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.

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.

Consolidated Cash Flows

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. Net cash provided by operating activities was $2.7 million for the six months ended June 30, 2015 compared to $78.1 million for the same period in 2014. The net decrease in cash flow from operations during the six months ended June 30, 2015 was largely attributable to a large claims payment made in June of 2015 with expected reinsurance recoverables to be received in July and August of 2015. Additionally, we experienced increased 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 used in investing activities was $4.8 million for the six months ended June 30, 2015 compared to $92.7 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 $0.6 million for the six months ended June 30, 2015 and 2014.

Investments

Our investment portfolio is invested primarily in publicly traded, investment grade, fixed income securities with an average credit quality of AA/Aa as rated by S&P or Moody’s Investors Service (“Moody’s”). As of June 30, 2015, our portfolio had a duration of 3.8 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. As of June 30, 2015 and December 31, 2014, all fixed maturities and equity securities held by us were classified as available-for-sale.

The portfolio is externally managed by independent, professional investment managers and is broadly diversified across geographies, sectors, and issuers. The primary objectives are to maximize total investment return in the context of preserving the statutory surplus of the insurance companies and enhancing shareholder value. The investments are subject to the oversight of the respective insurance companies’ Board of Directors and the Finance Committee of the Parent Company’s Board of Directors.

We are a specialty insurance company and periods of moderate economic recession or inflation tend not to have a significant direct effect on 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 following table summarizes the composition of our investments at fair value:

	Fair Value as of

Total Investments	$	2,710,763	$	2,729,735		-0.7	%

Invested assets decreased from December 31, 2014 primarily due to an increase in Treasury rates as well as spread widening. The decrease in U.S. Treasury, agency and foreign government bonds is due to a strategic reallocation to municipal and corporate bonds in an effort to enhance portfolio yield. During 2015, operating cash flows were invested in equity securities to compensate for lower yields in fixed income.

We own $67.9 million of municipal securities, which are credit enhanced by various financial guarantors. As of June 30, 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 (“AMBS”) 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 June 30, 2015:

Total residential mortgage-backed securities	$	32,396	$	31,488

We analyze our mortgage-backed securities by credit quality of the underlying collateral distinguishing between the securities issued by FNMA, FHLMC and GNMA, which are federal government sponsored entities, and 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 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.

Details of the collateral of our asset-backed securities portfolio as of June 30, 2015 are presented below:

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 June 30, 2015, the fair value of such securities was $86.9 million, with an amortized cost of $86.7 million, representing 3.5% of our total fixed maturities and equity portfolio. Our largest exposure is in the Netherlands with a total of $39.7 million followed by France with a total of $25.6 million. We have no direct exposure to Greece, Portugal, Italy or Spain within the Euro Area, or Ukraine or Russia as of June 30, 2015.

The following table summarizes the gross unrealized investment losses as of June 30, 2015 by length of time where the fair value was less than 80% of amortized cost:

	As of June 30, 2015
	Fixed		Equity
amounts in thousands	Maturities		Securities		Total
Less than twelve months	$	738	$	—	$	738
Longer than twelve months		—		—		—
Total	$	738	$	—	$	738

The $0.7 million unrealized loss is due to unfavorable foreign exchange movement.

Our Company had one credit related OTTI loss of $0.4 million from our equity portfolio during the three and six months ended June 30, 2015. The Company did not have any credit related OTTI losses during the three and six months ended June 30, 2014. 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.

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 premiums

• 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 our 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, 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.

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 our 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) There have been no changes during our second 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 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 losses 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.

Organization and Summary of Significant Accounting Policies

6 Months Ended

Jun. 30, 2015

Organization and Summary of Significant Accounting Policies

Note 1. Organization and Summary of Significant Accounting Policies

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 & Omissions (“E&O”) 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.

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.

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 (loss) in the Consolidated Statements of Income.

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 2015, the Financial Accounting Standards Board issued the following new pronouncements that may have an impact on our Company and we are assessing the future impact of these updates to our Consolidated Financial Statements:

• 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.

• Accounting Standards Update 2015-05 – Intangibles – Goodwill and Other – Internal Use Software (Subtopic 350-40) Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, which will be effective for fiscal years beginning after December 15, 2015. The new pronouncement was issued to provide guidance to customers about whether a cloud computing arrangement includes a software license.

• Accounting Standards Update 2015-07 – Fair Value Measurement – (Topic 820) Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or its equivalent) (a consensus of the Emerging Issues Task Force), which will be effective for fiscal years beginning after December 15, 2015. The new pronouncement was issued to ensure that all investments categorized in the fair value hierarchy are classified using a consistent approach.

• Accounting Standards Update 2015-09 – Financial Services Insurance – (Topic 944) Disclosures about Short-Duration Contracts, effective for annual periods beginning after December 15, 2015. The new pronouncement was issued to (1) increase the usefulness of the information about a reporting entity’s insurance liabilities, including the nature, amount, timing, and uncertainty of cash flows related to those liabilities and the effect of those cash flows on the Statements of Comprehensive Income and (2) improve comparability between reporting entities, regardless of the type of entity issuing the contract.

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 June 30, 2015 and December 31, 2014:

As of June 30, 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 June 30, 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 $0.6 million and $0.7 million, respectively.

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 June 30, 2015 are shown in the following table:

	As of June 30, 2015
amounts in thousands	Fair Value		Amortized Cost
Due in one year or less	$	64,435	$	67,319
Due after one year through five years		721,735		713,956
Due after five years through ten years		350,030		345,148
Due after ten years		389,728		385,292
Mortgage- and asset-backed securities		788,009		779,422
Total	$	2,313,937	$	2,291,137

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 4.7 years.

The following tables summarize all securities in a gross unrealized loss position as of June 30, 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:

As of June 30, 2015, there were 345 fixed maturities and 49 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 principally due to an unfavorable foreign exchange movement. As of December 31, 2014, there were 259 fixed maturities and 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 June 30, 2015 and December 31, 2014, the largest unrealized loss by a non-government backed issuer in the investment portfolio was $0.9 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, severity 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 payments 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 had one credit related OTTI loss of $0.4 million in the equity portfolio during the three and six months ended June 30, 2015. The Company did not have any credit related OTTI losses during the three and six months ended June 30, 2014.

As of June 30, 2015 and 2014, the cumulative amounts related to our Company’s credit loss portion of the OTTI losses on fixed maturities were $2.4 million and $5.2 million, respectively. There was no activity for the three and six months ended June 30, 2015 and 2014 related to these amounts. 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.

Stock Options, Stock Grants, SARs and ESPP

Note 7. 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. For the six months ended June 30, 2015 we granted 197,708 stock incentive units at a grant price between $73.62 and $78.86. Each performance unit and restricted stock unit represents a contingent right to receive one share of common stock as of the vesting date. Such common stock may be subject to forfeiture for the payment of any required tax withholding.

Ceded Reinsurance

Note 5. Ceded Reinsurance

As of June 30, 2015, the credit quality distribution of our Company’s Reinsurance recoverable of $1.2 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 June 30, 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 June 30, 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.

Commitments and Contingencies

Commitments and Contingencies

Note 6. 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 June 30, 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 $0.3 million and $0.5 million of the incentive for the three and six months ended June 30, 2015, respectively. As of June 30, 2015 and December 31, 2014, our Company has deferred revenue of $5.6 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 losses 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.

Organization and Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2015

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 & Omissions (“E&O”) 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.

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.

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 (loss) in the Consolidated Statements of Income.

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 2015, the Financial Accounting Standards Board issued the following new pronouncements that may have an impact on our Company and we are assessing the future impact of these updates to our Consolidated Financial Statements:

• 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.

• Accounting Standards Update 2015-05 – Intangibles – Goodwill and Other – Internal Use Software (Subtopic 350-40) Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, which will be effective for fiscal years beginning after December 15, 2015. The new pronouncement was issued to provide guidance to customers about whether a cloud computing arrangement includes a software license.

• Accounting Standards Update 2015-07 – Fair Value Measurement – (Topic 820) Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or its equivalent) (a consensus of the Emerging Issues Task Force), which will be effective for fiscal years beginning after December 15, 2015. The new pronouncement was issued to ensure that all investments categorized in the fair value hierarchy are classified using a consistent approach.

• Accounting Standards Update 2015-09 – Financial Services Insurance – (Topic 944) Disclosures about Short-Duration Contracts, effective for annual periods beginning after December 15, 2015. The new pronouncement was issued to (1) increase the usefulness of the information about a reporting entity’s insurance liabilities, including the nature, amount, timing, and uncertainty of cash flows related to those liabilities and the effect of those cash flows on the Statements of Comprehensive Income and (2) improve comparability between reporting entities, regardless of the type of entity issuing the contract.

There were no additional pending accounting pronouncements that are expected to have a significant impact on the Consolidated Financial Statements upon adoption.

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), Other income (loss) primarily consisting of foreign exchange gain (loss) and Income tax (expense) benefit, 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, P&C and Professional Liability.

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 losses 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 segment.

The accounting policies used to prepare the segment reporting data for our reportable 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 and six months ended June 30, 2015 and 2014 was as follows:
