THE NAVIGATORS GROUP, INC. AND SUBSIDIARIES

Notes to Interim Consolidated Financial Statements (Unaudited)

NOTE 1.  ORGANIZATION & 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.  We also offer Property and Casualty (“P&C”) insurance business, primarily 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 Directors & Officers (“D&O”) and Errors & Omissions (“E&O”) divisions.  Beginning in 2010, we added reinsurance products through our Global Reinsurance (“GlobalRe”) business.

We operate through various wholly-owned subsidiaries, including Navigators Insurance Company (“NIC”), inclusive of its United Kingdom Branch (“U.K. Branch”), and Navigators Specialty Insurance Company (“NSIC”), both of which are U.S. insurance companies, and Navigators Underwriting Agency Ltd. (“NUAL”), a Lloyd’s of London (“Lloyd’s”) underwriting agency that manages Lloyd’s Syndicate 1221 (the “Syndicate”) in the U.K. and is the primary underwriting company of Navigators Holdings (U.K.) Ltd. (“NHUK”), the holding company for our non U.S. domiciled entities. Our 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, 2015.  Certain amounts for the prior period have been reclassified to conform with the current period presentation.

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, 2016, we adopted the following accounting pronouncements, which did not have a material effect, singly or in the aggregate, on our consolidated financial condition, results of operations or cash flows:

· Accounting Standards Update 2015-03 – Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs, which is 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 is 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 is 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.

8

In 2016, 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 2016-01 – Financial Instruments (Subtopic 825-10) – Recognition and Measurement of Financial Assets and Financial Liabilities, which will be effective for fiscal years beginning after December 15, 2017.  The new pronouncement was issued to make targeted improvements to the presentation of financial instruments.

· Accounting Standards Update 2016-02 – Leases (Topic 842) - Amends the recognition of a right-to-use asset and lease liability on the statement of financial position of those leases previously classified as operating leases under the previous guidance, which will be effective for fiscal years beginning after December 15, 2015.  The new pronouncement was issued to improve transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements.

· Accounting Standards Update 2016-09 – Compensation – Stock Compensation – (Topic 718) - Improvements to Employee Share-Based Accounting, which will be effective for fiscal years beginning after December 15, 2016.  The new pronouncement was issued to simplify employee share-based accounting.

· Accounting Standards Update 2016-13 – Financial Instruments – Credit Losses (Topic 326) - amends the measurement of credit losses on financial instruments not accounted for at fair value including loans, debt securities, reinsurance receivables and any other financial assets, which will be effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years.

There were no additional 2016 accounting pronouncements that are expected to have an impact on the Consolidated Financial Statements upon adoption.

NOTE 2.  SEGMENT INFORMATION

We report our results of operations consistent with the manner in which our Chief Operating Decision Maker reviews the business to assess performance through our reportable segments: U.S. Insurance, International Insurance (“Int’l Insurance”), Global Reinsurance (“GlobalRe”) and Corporate. 

We classify our business into three underwriting segments: U.S. Insurance, Int’l Insurance and GlobalRe.  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 2 of our Annual Report on Form 10-K for the year ended December 31, 2015.

As of June 30, 2016 and December 31, 2015, our Company did not have a concentration of greater than 5% of invested assets in a single non-government backed issuer.

As of June 30, 2016 and December 31, 2015, Fixed maturities for which non-credit OTTI was previously recognized and included in AOCI are now in an unrealized gains position of $0.4 million and $0.5 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, 2016 are shown in the following table:

	June 30, 2016
	Fair		Amortized
amounts in thousands	Value		Cost
Due in one year or less	$	98,463	$	100,526
Due after one year through five years		842,667		827,241
Due after five years through ten years		289,220		273,903
Due after ten years		433,492		405,896
Mortgage-backed and asset-backed securities		968,471		951,055
Total	$	2,632,313	$	2,558,621

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 4.2 years.

As of June 30, 2016, there were 140 Fixed maturities and 30 Equity securities in an unrealized loss position. As of December 31, 2015, there were 368 Fixed maturities and 57 Equity securities in an unrealized loss position. As of  June 30, 2016 and December 31, 2015, 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. The gross unrealized loss for the less than 12 months category for the period ending  December 31, 2015 consists primarily of corporate bonds in the energy sector which have been impacted by the recent decline in oil prices.    

As of June 30, 2016 and December 31, 2015, the largest unrealized loss by a non-government backed issuer in the investment portfolio was $1.0 million and $2.6 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.  

Our Company reviews the magnitude of a security’s unrealized loss compared to its cost/amortized cost and the length of time that the security has been impaired to determine if an unrealized loss is other-than-temporary.  If warranted as a result of conditions relating to

14

a particular security, our Company will also review securities with declines in fair value resulting from a headline news event involving the issuer, a headline news event involving the asset class, the advice of our external asset managers, or economic events that may impact the issuer to determine if an unrealized loss is other-than-temporary.  The depth of analysis performed is dependent upon the nature and magnitude of the indicators of other-than-temporary impairment present in regards to each impaired security.

For equity securities, our Company performs a fundamental analysis of the issuer, including an evaluation of the mean analysts target price, to assess the likelihood of recovery of our cost basis in the security. Management also assesses the likelihood of future cash flows, dividends and increases to dividends, all of which affect the securities eligibility for our equity strategy and therefore our intent to hold the security.  If an equity security is deemed to be other-than-temporarily-impaired, the cost is written down to fair value with the cost recognized in earnings.

For fixed maturities, our Company assesses the underlying fundamentals of each issuer to determine if there is a change in the amount or timing of expected cash flows.  Management compares the amortized cost basis to the present value of the revised cash flows using the historical book yield to determine the credit loss portion of impairment which is recognized in earnings.  All non-credit losses where we have the intent and ability to hold the security until recovery are recognized as changes in OTTI losses within AOCI.

Specifically for structured fixed maturities, our Company analyzes 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.  For securities in which a tranche loss is present and the net present value of loss adjusted cash flows is less than book value, credit impairment is recognized in earnings. 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, which differ based on property type, vintage and the stress of the collateral.  

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.  

As of June 30, 2016, our Company does not intend to sell, and it is more-likely-than-not that it will not be required to sell any of its securities with unrealized losses before they recover in value.

Our Company had one credit related OTTI loss of $0.2 million in the Fixed maturities portfolio during the three and six months ended June 30, 2016.  Our Company had one credit related loss of $0.4 million in the equity portfolio during the three and six months ended June 30, 2015.

The following table summarizes the cumulative amounts related to our Company’s credit loss portion of the OTTI losses on Fixed maturities for the three and six months ended June 30, 2016 and 2015:

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.

16

The following tables present, for each of the fair value hierarchy levels as defined by the accounting guidance for fair value measurements and described above, 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, 2016 and December 31, 2015:

NOTE 5. CEDED REINSURANCE

As of June 30, 2016, the credit quality distribution of our Company’s Reinsurance recoverable of $1.1 billion for ceded paid losses, ceded unpaid losses and LAE, and ceded unearned premiums based on insurer financial strength ratings from A.M. Best or S&P was not significantly different from the credit quality distribution as of December 31, 2015.

Our allowance for uncollectible reinsurance was $6.9 million as of June 30, 2016 and December 31, 2015.

As of June 30, 2016, our 10 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, 2015.

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.  Under the terms of the agreement with the State, our Company was required to maintain an average of 100 full-time employees in Connecticut over a 12-month period in order for the State to forgive the initial $6.0 million of the loan.  In addition, as soon as our Company achieved a total of 150 full-time employees in Connecticut, we became eligible to receive an additional $1.0 million of the loan and $0.5 million of the grant.  On October 20, 2015, our Company received a letter from the State determining that we had achieved both of these milestones.  As a result, our Company earned a loan forgiveness credit of $6.0 million with the State and received the  additional $1.0 million of the loan and $0.5 million of the grant.  Earning of the remaining portions of the grant and forgiveness of any outstanding amounts of the loan is subject to certain conditions, including maintaining a certain number of required jobs for an extended period of time.  The length of time commitment for forgiveness of the additional $1.0 million of the October 20, 2015 loan has not yet been met. However, our Company expects to meet all the conditions for the State to forgive the loan. Accordingly, our Company is recognizing the amount of loan and grants received over the period in which offsetting expenses are recognized. Our Company recognized $0.4 million and $0.8 million of the incentive for the three and six months ended June 30, 2016. As of June 30, 2016 and December 31, 2015, our Company has deferred revenue of $5.5 million and $6.3 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 to the proceedings or directly as defendants.  Most of these proceedings consist of claims litigation involving our 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 effect on our Company’s Consolidated Statements of Income or Consolidated Statements of Cash Flows in a particular fiscal quarter or year.

NOTE 7.  STOCK-BASED COMPENSATION

Stock-based compensation granted under our 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, 2016, we granted 213,473 stock incentive units at a grant price between $80.98 and $91.48.  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.

NOTE 8. STOCKHOLDERS’ EQUITY

On May 26, 2016, our Board of Directors declared its intention to pay a regular quarterly cash dividend on The Navigators Group, Inc. Common Stock of $0.09 per share, payable on July 15, 2016 to Stockholders of record on June 20, 2016.  This initial dividend was recorded in the Consolidated Balance Sheets as of June 30, 2016 and subsequently paid on July 15, 2016.  However, the declaration and amount of any future dividend will be at the discretion of the Board of Directors, and will depend upon many factors, including financial condition, results of operations, business requirements, regulatory and legal constraints and other factors the Board of Directors deems relevant.

NOTE 9. SUBSEQUENT EVENTS

On August 4, 2016, our Board of Directors declared a cash dividend on The Navigators Group, Inc. Common Stock of $0.09  per share, payable on September 30, 2016 to Stockholders of record on August 19, 2016.

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 2015 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), Combined ratio, Net operating earnings, Net losses and LAE reserves and Book value 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 incurred, Commission expenses and Other operating expenses from Net earned premiums.  This information is available in total and by segment in Note 2 – Segment Information in the Interim Consolidated Financial Statements as of June 30, 2016.  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  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 Operating Earnings

Net operating earnings is calculated as Net income before after-tax Net realized gains (losses), after-tax OTTI losses recognized in earnings, and after-tax net 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 U.S. dollars (“USD”)).

20

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 losses and LAE reserves 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.

Overview

The discussion and analysis of our financial condition and results of operations contained herein should be read in conjunction with our 2015 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.  We also offer P&C insurance business, primarily 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 D&O and E&O divisions.  Beginning in 2010, we added reinsurance products through our GlobalRe reporting segment.

In May 2016, our Company received authorization from the Prudential Regulation Authority and the Financial Conduct Authority for a new U.K. based insurance company, Navigators International Insurance Company Ltd (“NIIC”),which is a wholly-owned direct subsidiary of our Parent Company. We are evaluating operational plans and determining when we will start writing business for NIIC, particularly in light of the announcement that the result of the U.K. referendum held on June 23, 2016 was that a majority voted in favor of the U.K. leaving the European Union (the “E.U.”), commonly referred to as “Brexit”.  See Item 1A. Risk Factors for additional discussion on Brexit.

Underwriting Profit (Loss)

Underwriting profit was $1.1 million for the three months ended June 30, 2016, comprised of $10.8 million and $0.3 million underwriting profit from our U.S. Insurance and GlobalRe reporting segments respectively, partially offset by an underwriting loss of

22

$10.1 million from our Int’l Insurance reporting segment. For the three months ended June 30, 2015, we reported an underwriting profit of $16.1 million comprised of $9.6 million, $4.3 million and $2.2 million from our U.S. Insurance, GlobalRe and Int’l Insurance reporting segments, respectively.

Underwriting profit was $14.1 million for the six months ended June 30, 2016, comprised of $19.4 million and $4.3 million underwriting profit from our U.S. Insurance and GlobalRe reporting segments respectively, partially offset by an underwriting loss of $9.6 million from our Int’l Insurance reporting segment.  Underwriting profit was $34.3 million for the six months ended June 30, 2015 comprised of $15.1 million, $9.6 million, and $9.6 million for our U.S. Insurance, Int’l Insurance and GlobalRe reporting segments, respectively.  

For additional information on the drivers of Underwriting profit see the U.S. Insurance, Int’l Insurance and GlobalRe reporting segment results sections included herein.

A major component of our Underwriting profit (loss) is due to Net losses and LAE.  The following tables present the impact of changes in reserves and reinsurance reinstatement premiums (“RRPs”) on our Net losses and LAE ratio for the three and six months ended June 30, 2016 and 2015 (note: accident year is abbreviated “AY”):

	Three Months Ended June 30,						Point
	2016			2015			Change
Net losses and LAE ratio, reported		62.4	%		58.6	%		3.8
RRPs		-0.7	%		0.4	%		-1.1

Net losses and LAE ratio, adjusted		57.2	%		59.9	%		-2.7

	Six Months Ended June 30,						Point
	2016			2015			Change
Net losses and LAE ratio, reported		60.1	%		56.9	%		3.2
RRPs		-0.3	%		0.1	%		-0.4
Additional net current AY reserve release/(development)		-4.4	%		-1.6	%		-2.8
Net prior AY reserve release/(strengthening)		2.0	%		4.2	%		-2.2
Net losses and LAE ratio, adjusted		57.4	%		59.6	%		-2.2

For the three months ended June 30, 2016, we recorded $20.9 million of additional net current AY reserve development, mostly due to $16.4 million of catastrophic events (“CAT”), including $12.5 million related to the Alberta Wildfires, $2.9 million due to the Ecuador Earthquake, and $1.1 million due to the Taiwan Earthquake, as well as, $4.5 million of non-CAT additional net current AY reserve development from our Int’l Insurance and U.S. Insurance reporting segments.  In addition, the quarter was unfavorably impacted by $3.1 million of RRPs, mostly related to the CATs noted above. This was partially offset by $8.8 million of net prior AY reserve releases including $4.0 million, $3.4 million and $1.4 million from our U.S. Insurance, Int’l Insurance and GlobalRe reporting segments, respectively.

For the three months ended June 30, 2015, we recorded $7.3 million of net prior AY reserve releases comprised of $7.8 million from our U.S. Insurance reporting segment, slightly offset by a net prior AY reserve strengthening of $0.6 million from Int’l Insurance. The favorable net prior AY reserve releases were partially offset by additional net current AY reserve development of $5.0 million within U.S. Insurance.

For the six months ended June 30, 2016, we recorded $23.3 million of additional net current AY reserve development, of which $18.3 million was due to CATs, including the events noted above, as well as an additional $1.8 million from the Taiwan Earthquake, incurred in the first quarter.  In addition, we recorded $5.0 million non-CAT additional net current AY reserve development from our Int’l Insurance and U.S. Insurance reporting segments as well as $2.3 million of RRPs. This was partially offset by $10.6 million of net prior AY reserve releases including $6.7 million, $2.5 million and $1.4 million from our U.S. Insurance, Int’l Insurance and GlobalRe reporting segments, respectively.

For the six months ended June 30, 2015, we recorded $19.9 million of net prior AY reserve releases comprised of $14.2 million and $5.6 million our U.S. Insurance and Int’l Insurance reporting segments, respectively.  The favorable net prior AY reserve releases were partially offset by $7.5 million of additional net current AY reserve development related to large loss activity in our U.S. Insurance and GlobalRe reporting segments.

Net Investment Income

23

Our Net investment income was derived from the following sources:

	Three Months Ended June 30,						Six Months Ended June 30,
amounts in thousands	2016			2015			2016			2015
Fixed maturities	$	16,920		$	15,259		$	33,657		$	30,308
Equity securities		3,431			1,873			6,878			3,840
Short-term investments		288			146			498			330
Total investment income	$	20,639		$	17,278		$	41,033		$	34,478
Investment expenses		(764	)		(683	)		(1,564	)		(1,630	)
Net investment income	$	19,875		$	16,595		$	39,469		$	32,848

The increase in Total investment income for the three and six months ended June 30, 2016 as compared to the same period in the prior year was primarily due to growth of invested assets, coupled with an increase in the overall portfolio yield, mostly due to the increased allocation to preferred stocks. The annualized pre-tax yield, excluding Net realized gains and losses and OTTI losses recognized in earnings, for the three months ended June 30, 2016 and 2015, was 2.6% and 2.4%, respectively.  The annualized pre-tax yield, excluding Net realized gains and losses and OTTI losses recognized in earnings, for the six months ended June 30, 2016 and 2015, was 2.6% and 2.4%, respectively.  

As part of our overall investment strategy, we seek to build a tax efficient investment portfolio.  The tax exempt portfolio was 17.6% of the fixed maturities portfolio as of June 30, 2016.  Additionally, substantially all of our equity portfolio is invested in tax efficient securities which qualify for the dividends received deduction.  The tax equivalent yield for the three months ended June 30, 2016 and 2015, was 2.8% and 2.6%, respectively. The tax equivalent yield for the six months ended June 30, 2016 and 2015 was 2.8% and 2.5%, respectively.

OTTI Losses Recognized in Earnings

Our Company  had one credit related OTTI loss of $0.2 million in the Fixed maturities portfolio during the three and six months ended June 30, 2016. Our Company had one credit related loss of $0.4 million in the equity portfolio during the three and six months ended June 30, 2015.

Net Realized Gains and Losses

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

	Three Months Ended June 30,						Six Months Ended June 30,
amounts in thousands	2016			2015			2016			2015
Fixed maturities:
Gains	$	1,296		$	1,231		$	3,844		$	2,405
Losses		(738	)		(1,518	)		(1,865	)		(2,090	)
Fixed maturities, net	$	558		$	(287	)	$	1,979		$	315
Short-term:
Gains	$	407		$	112		$	675		$	26
Losses		(60	)		(11	)		(143	)		(79	)
Short-term, net	$	347		$	101		$	532		$	(53	)
Equity securities:
Gains	$	1,071		$	4,753		$	1,680		$	11,078
Losses		(16	)		(228	)		(634	)		(1,405	)
Equity securities, net	$	1,055		$	4,525		$	1,046		$	9,673
Net realized gains (losses)	$	1,960		$	4,339		$	3,557		$	9,935

Net realized gains and losses are generated as part of the normal ongoing management of our investment portfolio. Net realized gains of $2.0 million for the three months ended June 30, 2016 are primarily due to the sale of equity securities and corporate bonds, partially offset by realized losses in the Fixed maturities portfolio primarily driven by foreign currency losses on our Canadian portfolio. Net realized gains of $3.6 million for the six months ended June 30, 2016, are primarily due to the sale of corporate and municipal bonds, offset by realized losses in the Fixed maturities portfolio primarily driven by foreign currency losses in our Canadian portfolio. Net realized gains of $4.3 million and $9.9 million for the three and six months ended June 30, 2015 are primarily due to the sale of Equity securities.

24

Interest Expense

Interest expense was $3.9 million and $7.7 million for three and six months ended June 30, 2016, 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, is approximately 5.86%.  

Other Income (Loss)

Other income (loss) for the three and six months ended June 30, 2016 was a $4.4 million gain and a $6.9 million gain, respectively, and primarily consists of realized and unrealized foreign exchange gains and losses.  The current quarter foreign exchange gains are mostly driven by the strengthening of the USD against the British pound (“GBP”).  

Income Taxes

We recorded an Effective tax rate of 30.3% for the three and six months ended June 30, 2016, compared to 32.4% for the same periods in 2015.  The decrease of 2.1 points is driven by the benefit of the dividends received deduction from our increased investment portfolio allocation to preferred stocks.  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.

Gross Written Premiums

Gross written premiums increased $3.9 million for the three months ended June 30, 2016 compared to the same period in 2015 driven by a $4.4 million increase in our U.S. Marine operating segment primarily due to new business production across certain key products. In addition, our U.S. Professional Liability operating segment increased $1.1 million benefitting from new business production.  Our U.S. P&C operating segment decreased $1.6 million primarily driven by decreases of $8.6 million and $2.8 million in Primary Casualty and Excess Casualty, respectively, due to difficult market conditions, partially offset by increases of $5.8 million in our Property product introduced in 2016, $2.1 million in our Auto product due to new business production, and $1.6 million in our Life Sciences product attributed to the expansion of our underwriting team.  

Gross written premiums increased $15.3 million for the six months ended June 30, 2016 compared to the same period in 2015 driven by a $6.7 million increase in our U.S. Marine operating segment due to new business production within Cargo and Craft products, and a $5.6 million increase in our U.S. P&C operating segment due to new business production from our Property, Auto and Life Sciences products, partially offset by declines in Excess Casualty and Primary Casualty divisions as a result of difficult market conditions. In addition, our U.S. Professional Liability operating segment increased $3.0 million due to new business production and increased renewals in the D&O product.

Average renewal premium rates for our U.S. Insurance reporting segment for the  three months ended June 30, 2016 decreased 0.1%  driven by decreases of 2.8% and 0.9% within our U.S. Marine and U.S. Professional Liability operating segments, respectively, slightly offset by a 0.6% increase in our U.S. P&C operating segment.  The decrease in rates within U.S. Marine and Professional Liability operating segments were offset by new business production.

For the six months ended June 30, 2016, average renewal premium rates increased 0.1% driven by 1.3% within our U.S. Marine operating segment, mostly offset by decreases of 0.2% in our U.S. P&C and U.S. Professional Liability operating segments, respectively.

Ceded Written Premiums

Ceded written premiums decreased $16.3 million and $30.5 million for the three and six months ended June 30, 2016 compared to the same periods in 2015, primarily due to a reduction in our proportional reinsurance coverage on our Excess Casualty and Environmental Casualty risks as well as the nonrenewal of our Professional Liability proportional reinsurance treaty in the fourth quarter 2015.

29

Net Earned Premiums

Net earned premiums increased $15.1 million and $32.3 million for the three and six months ended June 30, 2016 compared to the same period in 2015, primarily due to growth in Gross written premiums and a reduced level of proportional reinsurance that supports certain casualty risks within our U.S. P&C operating segment.

For the three months ended June 30, 2016, our U.S. Insurance reporting segment recorded $4.0 million of net prior AY reserve releases from our U.S. Marine operating segment due to favorable loss emergence.  This was partially offset by additional net current AY reserve development of $1.5 million from our Energy & Engineering division within our U.S. P&C operating segment, as well as RRPs of $0.6 million from our U.S. Marine operating segment.

For the three months ended June 30, 2015, our U.S. Insurance reporting segment recorded $7.8 million of net prior AY reserve releases, including $4.3 million and $3.6 million of reserve release from our U.S. Professional Liability and U.S. Marine operating segments, respectively, due to a decline in large loss activity, partially offset by $5.0 million of additional net current AY reserve development within our Energy & Engineering division due to large loss activity.

For the six months ended June 30, 2016, our U.S. Insurance reporting segment recorded $6.7 million of net prior AY reserve releases, comprised of $7.7 million from our U.S. Marine operating segment due to favorable loss emergence, partially offset by $1.0 million of reserve strengthening from our Primary Casualty division within our U.S. P&C operating segment, as well as, $1.5 million of

30

additional net current AY reserve development due to large loss activity within our Energy & Engineering division, and RRPs of $0.4 million from our U.S. Marine operating segment.

For the six months ended June 30, 2015, our U.S. Insurance reporting segment recorded $14.2 million of net prior AY reserve releases primarily comprised of $8.0 million, $5.2 million and $1.1 million of reserve releases from our U.S. Marine, U.S. Professional Liability and U.S. P&C operating segments, respectively, due to a decline in large loss activity as well as collections of recoverables previously written off, partially offset by $5.0 million additional net current AY reserve development within our Energy & Engineering division due to large loss activity and $1.4 million of RRPs primarily from our U.S. Marine operating segment.

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

Commission Expenses

The Commission expense ratio for the three and six months ended June 30, 2016 increased 2.2 and 0.7 points, respectively, as compared to the same periods in 2015, primarily driven by a reduction in ceded commission benefit within our U.S. P&C operating segment resulting from a reduction in our proportional reinsurance that supports Excess Casualty, Life Sciences, and Environmental casualty risks, and to a lesser extent, within our U.S. Professional Liability operating segment due to the nonrenewal of our U.S. Professional Liability proportional treaty in the fourth quarter of 2015.  

Other Operating Expenses

Other operating expenses increased $0.2 million and $0.3 million for the three and six months ended June 30, 2016, respectively, compared to the same periods in 2015 due to the continued investment in our underwriting teams and support staff.

Gross Written Premiums

Gross written premiums increased $26.9 million for the three months ended June 30, 2016 compared to the same period in 2015, driven by growth in our Int’l P&C and Professional Liability operating segments. Our Int’l P&C operating segment has increased by $21.4 million, primarily driven by continued growth in our Property division as well our new Int’l Political Violence & Terror (“PV&T”) product. Our Int’l Professional Liability operating segment has increased by $5.8 million, primarily driven by increases in our E&O and D&O divisions including growth of $1.9 million from our European offices. Our Int’l Marine operating segment decreased by $0.3 million due to decreases in our Protection & Indemnity (“P&I”) and Marine Liability products, partially offset by growth in our Hull and Energy Liability products.

Gross written premiums increased $48.7 million for the six months ended June 30, 2016 compared to the same period in 2015, driven by growth in all our Int’l Insurance operating segments. Our Int’l P&C operating segment has increased by $32.5 million mainly due to continued growth in our Property and Excess Casualty divisions as well as our new PV&T product. Our Int’l Professional Liability operating segment has increased by $11.9 million mainly driven by increased premium from our D&O and  E&O divisions. Our Int’l Marine operating segment increased by $4.3 million mainly driven by growth in our Cargo, Hull and Transport products, slightly offset by a decrease in our Marine Liability product.

Average renewal premium rates for our Int’l Insurance reporting segment for the three and six months ended June 30, 2016 decreased 6.2% and 4.4% respectively. The decline for the three months was driven by decreases of 11.6%, 4.3% and 2.1% 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 9.9%, 4.3% and 1.2% in our Int’l P&C, Int’l Professional Liability and Int’l Marine operating segments, respectively.

Ceded Written Premiums

Ceded written premiums increased $0.3 million and $1.0 million for the three and six months ended June 30, 2016 respectively, compared to the same periods in 2015 primarily driven by $2.3 million of RRPs, for both the three and six months compared to a RRPs accrual reduction for the same periods last year of $1.1 million for the three months and $1.3 million for the six months ended June 30, 2015. $1.9 million of the current periods RRPs is from our Int’l P&C operating segment due to losses from the recent Alberta Wildfires. The increase in RRPs is offset by decreases in our proportional reinsurance programs.  

Net Earned Premiums

Net earned premiums increased $14.6 million and $27.1 million for the three and six months ended June 30, 2016 respectively compared to the same periods in 2015, driven by the continued growth in our Int’l Professional Liability operating segment specifically in the E&O and D&O divisions as well as growth in our Property division and improvements in our Offshore Energy division within our Int’l P&C operating segment. This is partially offset by our Int’l Marine operating segment by a decrease in Marine Liability and War products as well as the RRPs noted above.

For the three months ended June 30, 2016, our Int’l Insurance reporting segment recorded $12.9 million of additional net current AY reserve development, including $9.8 million from CATs comprised of Alberta Wildfires of $7.5 million, the Ecuador Earthquake of $1.7 million, and the Taiwan earthquake of $0.7 million, as well as, $3.0 million of non-CAT additional net current AY reserve development from our Int’l P&C operating segment.  In addition, the quarter was unfavorably impacted by $2.3 million of RRPs, mostly related to the CAT losses incurred. This was partially offset by $3.4 million of net prior AY reserve releases primarily from our Int’l Marine operating segment due to favorable loss emergence.

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 $0.9 million strengthening from our Int’l Marine operating segment, partially offset by $0.4 million prior AY reserve releases from our Int’l P&C operating segment and favorable RRPs of $1.1 million.

For the six months ended June 30, 2016, our Int’l Insurance reporting segment recorded $14.7 million of additional net current AY reserve development, mostly comprised of the CATs, noted above as well as a first quarter loss of $1.2 million due to the Taiwan Earthquake and a net $3.6 million of non-CAT additional net current AY reserve development from our Int’l P&C operating segment.  In addition, we were unfavorably impacted by $2.3 million of RRPs as noted above.  This was slightly offset by $2.5 million of net prior AY reserve releases primarily from our Int’l Marine operating segment due to favorable loss emergence.

For the six months ended June 30, 2015, our Int’l Insurance reporting segment recorded $5.6 million of net prior AY reserve releases including $2.5 million, $2.3 million and $0.8 million from our Int’l Marine, Int’l P&C and Int’l Professional Liability operating

34

segments, respectively, as well as $2.0 million of favorable RRPs.  This was partially offset by $2.5 million of additional net current AY reserve development within our Int’l Marine operating segment due to large loss activity.

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, 2016  increased 3.7 points and 3.0 points, respectively, as compared to the same periods in 2015. This is mainly due to growth in net earned premium in our Property division within our Int’l P&C operating segment which has no ceded proportional reinsurance resulting in a change in business mix for 2016. In addition, there is also less proportional reinsurance across all our Int’l operating segments and to a lesser extent lower ceded reinsurance profit commissions in certain products compared to the same periods in the prior year.

Other Operating Expenses

For the three and six months ended June 30, 2016, Other operating expenses increased $5.7 million and $10.4 million, respectively, as compared to the same periods in 2015 due to continued investment in new underwriting teams and support staff, and increased Lloyd’s charges, partially offset by favorable foreign exchange rates.

Gross Written Premiums

Gross written premiums increased $2.2 million for the three months ended June 30, 2016, compared to the same period in 2015, primarily due to new business within our Agriculture and P&C products, partially offset by non-renewals within our Accident & Health (“A&H”) and Marine products.

Gross written premiums decreased $13.4 million for the six months ended June 30, 2016 compared to the same period in 2015, primarily due to non-renewals within our A&H product, partially offset by year over year written premium growth in our P&C and Agriculture products.

Ceded Written Premiums

Ceded written premiums increased $0.8 million and $0.9 million for the three and six months ended June 30, 2016, respectively, compared to the same periods in 2015, primarily due to increased net reinstatement premium in our Marine product, partially offset by a final true-up on our P&C 2015 retrocessional treaty and lower cost on our 2016 retrocessional treaties for our P&C product.

Net Earned Premiums

Net earned premiums decreased $4.1 million and $5.6 million for the three and six months ended June 30, 2016, respectively, compared to the same periods in 2015, primarily due to the continued impact of the non-renewals within our A&H product, partially offset by year over year growth in our P&C and Agriculture products.

Our GlobalRe reporting segment recorded $6.6 million of additional net current AY reserve development for the three months ended June 30, 2016, mostly related to CATs including the Alberta Wildfires of $5.0 million, the Ecuador Earthquake of $1.2 million and the Taiwan Earthquake of $0.4 million as well as $0.3 million of unfavorable RRPs.  This was partially offset by $1.4 million of net prior AY reserve releases, mostly from our Property and Professional Liability products.

For the three months ended June 30, 2015, our GlobalRe reporting segment was favorably impacted by $0.3 million of net favorable RRPs.  

Our GlobalRe reporting segment recorded $7.1 million of additional net current AY reserve development for the six months ended June 30, 2016, comprised of the CATs noted above, as well as a first quarter CAT loss incurred of $0.5 million from the Taiwan Earthquake, partially offset by $1.4 million of net prior AY reserve releases, as noted above, as well as net favorable RRPs of $0.4 million.

For the six months ended June 30, 2015, our GlobalRe reporting segment was favorably impacted by $0.5 million of net favorable RRPs.

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

Commission Expenses

The Commission expense ratio increased 0.6 points and 1.2 points for the three and six months ended June 30, 2016, respectively, compared to the same periods in 2015, due to mix of business changes, particularly a decrease in our A&H and Professional Liability excess of loss products which carry a lower commission rate, coupled with net outward RRPs in our Marine product.

Other Operating Expenses

Other operating expenses increased $0.4 million for the three months and $1.5 million for the six months ended June 30, 2016 compared to the same periods in 2015.  The increase is primarily due to employee expenses related to continued investment in our underwriting teams and support costs.

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, 2016 and December 31, 2015, our capital resources were as follows:

	As of
amounts in thousands	June 30, 2016			December 31, 2015
Senior notes	$	263,653		$	263,580
Stockholders' equity		1,181,558			1,096,148
Total capitalization	$	1,445,211		$	1,359,728
Ratio of debt to total capitalization		18.2	%		19.4	%

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, 2016, the maximum amount available for the payment of dividends by Navigators Insurance Company in 2016 without prior regulatory approval is $94.9 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, 2016, that amount was $0.9 million (£0.7 million).

Senior Notes and Credit Facility

On October 4, 2013, we completed a public debt offering for $265.0 million of 5.75% Senior notes and received net proceeds of $263.3 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. Interest is payable under this facility at a rate of 2.0% 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.  This credit 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 £75.0 million of Funds at Lloyd’s. As of June 30, 2016, letters of credit with an aggregate face amount of 8.0 million Australian Dollars were outstanding under the credit facility, and our Company was in compliance with all covenants.

On November 24, 2014, we 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, which is secured by all the common stock of NIC and requires us to maintain at least forty percent of the outstanding amounts under such facility as Funds at Lloyd’s. In addition, in order to support the increased underwriting capacity of the Syndicate for the 2016 underwriting year (“UWY”), we entered into $25.0 million credit facility with ING Bank N.V., London Branch on November 20, 2015. Both of these facilities, as well as the November 6, 2014 facility, are used to fund underwriting obligations at Lloyd’s for the 2016 UWY, as well as open prior UWYs.

The November 20, 2015 credit facility is a non-committed facility which has an applicable fee rate ranging from 0.85% to 1.20% per annum based upon our Company’s S&P rating. For the November 24, 2014 credit facility, the applicable fee rate payable ranges from 0.95% to 1.60% per annum based on a tiered schedule that is based on our then-current financial strength ratings issued by S&P and A.M. Best and the amount of our own collateral utilized to fund our participation in the Syndicate.  The letters of credit issued under both of these facilities can be denominated in GBP and their aggregate face amount will fluctuate based on exchange rates.  If any letters of credit remain outstanding under these facilities after December 31, 2016, we would be required to post additional collateral to secure the remaining letters of credit.  As of June 30, 2016, letters of credit with an aggregate face amount of $20.0 million and $175.0 million were outstanding under the November 20, 2015 and November 24, 2014 credit facilities, respectively, and we had an aggregate of $3.4 million of cash collateral posted.

38

Each of the November 20, 2015 and November 24, 2014 credit facilities 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. These credit facilities also provide 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 our subsidiaries, the occurrence of certain material judgments, or a change in control of our Company.  As of June 30, 2016, our Company was in compliance with all covenants.

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 our 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 $114.6 million for the six months ended June 30, 2016 compared to $2.7 million for the same period in 2015.  The increase in cash flow from operations during the six months ended June 30, 2016 was primarily due to increased premium collections, as well as fewer gross claim payments and more timely collections of reinsurance recoverables on paid losses.

Net cash used in investing activities was $55.1 million for the six months ended June 30, 2016 compared to $4.8 million for the comparable period in 2015.  The fluctuation in cash used in investing activities is predominately due to the capitalization of our U.K. based insurance company, NIIC.

Net cash provided by financing activities was $0.9 million for the six months ended June 30, 2016 compared to $0.6 million for the same period in 2015. The fluctuation in cash provided by financing activities is the result of transactions in our employee stock purchase plan.

Investments

Our investment portfolio is invested primarily in publicly traded, investment grade, fixed income securities with an average credit quality of AA-/Aa3 as rated by S&P or Moody’s Investors Service (“Moody’s”).  As of June 30, 2016, our portfolio had a duration of 3.9 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, 2016 and December 31, 2015, 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.  As part of our overall investment strategy, we seek to build a tax efficient investment portfolio.  As of June 30, 2016, the tax-exempt portion of our Fixed maturities portfolio was 17.6%.  Additionally, substantially all of our equity portfolio is invested in tax efficient securities which qualify for the dividends received deduction.  The investments are subject to the oversight of the respective insurance companies’ Boards of Directors and the Finance Committee of our 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:

Total investments	$	3,106,791	$	2,937,226		5.8	%

Invested assets increased from December 31, 2015 primarily due to positive cash flow from operations and to a lesser extent a decrease in Treasury rates and a rally in the equity markets which resulted in increased unrealized gains.  Operating cash flows were directed to sovereign bonds and to a lesser extent agency mortgage-backed securities as we look for market opportunities to further deploy funds.  The decrease in short term investments is offset by a corresponding increase in cash as we capitalized our new U.K based insurance company, NIIC.

The following table sets forth the amount of our Fixed maturities as of June 30, 2016 by S&P credit rating or, if an S&P rating is not available, the equivalent Moody’s rating. The total rating is the weighted average quality rating for the Fixed maturities portfolio as a whole.

We own $54.8 million of municipal securities, which are credit enhanced by various financial guarantors. As of June 30, 2016, 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.

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-agency backed 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 prime, 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, 2016 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, 2016, the fair value of such securities was $77.0 million, with an amortized cost of $75.3 million, representing 2.6% of our total Fixed maturities and equity portfolio.  Our largest exposure is in  the Netherlands with a total of $38.6 million.  We have no direct exposure to Greece, Portugal, Italy or Spain within the Euro Area as of June 30, 2016. Our Company holds fixed maturities issued by the Commonwealth of Puerto Rico which are fully backed by the U.S. government.

The following table summarizes the gross unrealized investment losses as of June 30, 2016 by length of time where the fair value was less than 80% of amortized cost:

	As of  June 30, 2016
	Fixed		Equity

Less than twelve months	$	—	$	814	$	814
Longer than twelve months		1,590		—		1,590
Total	$	1,590	$	814	$	2,404

The longer than twelve months unrealized loss of $1.6 million is due to unfavorable foreign exchange movement in our Canadian portfolio.

Our Company had one credit related OTTI loss of $0.2 million in the Fixed maturities portfolio during the three and six months ended June 30, 2016. Our Company had one credit related loss of $0.4 million in the equity portfolio during the three and six months ended June 30, 2015. 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

Our Company’s Annual Report on Form 10-K for the year ended December 31, 2015 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:

· 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; and

· Valuation of invested assets.

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 2015 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 GBP and the Canadian dollar (“CAD”).  We manage our foreign currency exchange rate risk primarily through asset-liability matching.

The following table shows foreign currency denominated net asset position in USD as of June 30, 2016 and December 31, 2015, and the expected dollar change in fair value that would occur if exchange rates changed 10% from exchange rates in effect at those times:

	As of  June 30,			As of December 31, (2)			As of  June 30,			As of December 31, (2)
	2016			2015			2016			2015

Total (1)	$	29,880		$	(28,486	)	$	(2,988	)	$	2,849

(1) Amount excludes additional currencies where the value of net assets in USD is less than 1 % of total net assets of our Company

(2) Amounts reported as of December 31, 2015 have been reclassified to include only monetary net assets to conform with current period presentation.

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, our 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 to the proceedings or directly as defendants.  Most of these proceedings consist of claims litigation involving our 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.

Item 1A. Risk Factors

There have been no material changes from the risk factors as previously disclosed in our Company’s 2015 Annual Report on Form 10-K, except for the addition of a risk factor relating to the U.K. referendum vote to leave the E.U. and the addition of a risk factor relating to the payment of dividends.

The withdrawal of the U.K. from the E.U. could have a material adverse effect on our business, business opportunities,results of operations, financial condition and cash flows.  

Although the Brexit referendum is non-binding, assuming the U.K. government triggers the relevant withdrawal provision of the E.U. Treaty by the end of 2016, it is expected that formal negotiations on the terms of the U.K.’s withdrawal from the E.U. will commence shortly thereafter. Our international operations are based in the U.K., and we have offices in the E.U. The effects of the withdrawal by the U.K. from the E.U. on our operations in the U.K. and E.U., and more particularly on our operations conducted at Lloyd’s, will depend on any agreements the U.K. or Lloyd’s makes to retain access to E.U. markets either during a transitional period or more permanently. However, a withdrawal could, among other outcomes, cause significant volatility in global stock markets, currency exchange rate fluctuations and asset valuations, and disrupt the U.K. market and the E.U. markets in which we serve and operate, by increasing restrictions on the trade and free movement of goods, services and people between the U.K. and the E.U.  In addition, any withdrawal could lead to legal uncertainty and potentially divergent national laws and regulations as the U.K. determines which E.U. laws to replace or replicate. The consequences of a withdrawal in the long term are unknown and not quantifiable at this time, but we do not believe that the withdrawal of the U.K. from the E.U. will have a material impact on our results of operations or financial condition in the short term. However, given the lack of comparable precedent, any of these effects of a withdrawal, among others, could materially adversely affect our business, business opportunities, results of operations, financial condition and cash flows.

The payment of dividends is at the discretion of our Board of Directors, and the reduction or elimination of dividends could cause a decline in the price of our common stock.

We are not obligated to pay dividends on our common stock. Any determinations by the Board of Directors to declare and pay cash dividends on the Company’s common stock will be based primarily upon the Company’s financial condition, results of operations, business requirements, regulatory and legal constraints and any other factors the Board of Directors deems relevant. Several of these factors will be subject to general economic, financial, competitive, legislative, regulatory factors beyond the Company’s control, and any reduction or elimination of dividends could cause the Company’s stock price to decline.

Accounting Policies [Abstract]

Organization and Summary of Significant Accounting Policies

NOTE 1.  ORGANIZATION & 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.  We also offer Property and Casualty (“P&C”) insurance business, primarily 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 Directors & Officers (“D&O”) and Errors & Omissions (“E&O”) divisions.  Beginning in 2010, we added reinsurance products through our Global Reinsurance (“GlobalRe”) business.

We operate through various wholly-owned subsidiaries, including Navigators Insurance Company (“NIC”), inclusive of its United Kingdom Branch (“U.K. Branch”), and Navigators Specialty Insurance Company (“NSIC”), both of which are U.S. insurance companies, and Navigators Underwriting Agency Ltd. (“NUAL”), a Lloyd’s of London (“Lloyd’s”) underwriting agency that manages Lloyd’s Syndicate 1221 (the “Syndicate”) in the U.K. and is the primary underwriting company of Navigators Holdings (U.K.) Ltd. (“NHUK”), the holding company for our non U.S. domiciled entities. Our 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, 2015.  Certain amounts for the prior period have been reclassified to conform with the current period presentation.

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, 2016, we adopted the following accounting pronouncements, which did not have a material effect, singly or in the aggregate, on our consolidated financial condition, results of operations or cash flows:

· Accounting Standards Update 2015-03 – Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs, which is 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 is 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 is 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.

In 2016, 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 2016-01 – Financial Instruments (Subtopic 825-10) – Recognition and Measurement of Financial Assets and Financial Liabilities, which will be effective for fiscal years beginning after December 15, 2017.  The new pronouncement was issued to make targeted improvements to the presentation of financial instruments.

· Accounting Standards Update 2016-02 – Leases (Topic 842) - Amends the recognition of a right-to-use asset and lease liability on the statement of financial position of those leases previously classified as operating leases under the previous guidance, which will be effective for fiscal years beginning after December 15, 2015.  The new pronouncement was issued to improve transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements.

· Accounting Standards Update 2016-09 – Compensation – Stock Compensation – (Topic 718) - Improvements to Employee Share-Based Accounting, which will be effective for fiscal years beginning after December 15, 2016.  The new pronouncement was issued to simplify employee share-based accounting.

· Accounting Standards Update 2016-13 – Financial Instruments – Credit Losses (Topic 326) - amends the measurement of credit losses on financial instruments not accounted for at fair value including loans, debt securities, reinsurance receivables and any other financial assets, which will be effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years.

There were no additional 2016 accounting pronouncements that are expected to have an impact on the Consolidated Financial Statements upon adoption.

Segment Reporting [Abstract]

Segment Information

NOTE 2.  SEGMENT INFORMATION

We report our results of operations consistent with the manner in which our Chief Operating Decision Maker reviews the business to assess performance through our reportable segments: U.S. Insurance, International Insurance (“Int’l Insurance”), Global Reinsurance (“GlobalRe”) and Corporate. 

We classify our business into three underwriting segments: U.S. Insurance, Int’l Insurance and GlobalRe.  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 2 of our Annual Report on Form 10-K for the year ended December 31, 2015.  

Financial data by segment for the three and six months ended June 30, 2016 and 2015 was as follows:

As of June 30, 2016 and December 31, 2015, our Company did not have a concentration of greater than 5% of invested assets in a single non-government backed issuer.

As of June 30, 2016 and December 31, 2015, Fixed maturities for which non-credit OTTI was previously recognized and included in AOCI are now in an unrealized gains position of $0.4 million and $0.5 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, 2016 are shown in the following table:

	June 30, 2016
	Fair		Amortized
amounts in thousands	Value		Cost
Due in one year or less	$	98,463	$	100,526
Due after one year through five years		842,667		827,241
Due after five years through ten years		289,220		273,903
Due after ten years		433,492		405,896
Mortgage-backed and asset-backed securities		968,471		951,055
Total	$	2,632,313	$	2,558,621

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 4.2 years.

The following tables summarize all securities in a gross unrealized loss position as of June 30, 2016 and December 31, 2015, 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, 2016, there were 140 Fixed maturities and 30 Equity securities in an unrealized loss position. As of December 31, 2015, there were 368 Fixed maturities and 57 Equity securities in an unrealized loss position. As of  June 30, 2016 and December 31, 2015, 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. The gross unrealized loss for the less than 12 months category for the period ending  December 31, 2015 consists primarily of corporate bonds in the energy sector which have been impacted by the recent decline in oil prices.    

As of June 30, 2016 and December 31, 2015, the largest unrealized loss by a non-government backed issuer in the investment portfolio was $1.0 million and $2.6 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.  

Our Company reviews the magnitude of a security’s unrealized loss compared to its cost/amortized cost and the length of time that the security has been impaired to determine if an unrealized loss is other-than-temporary.  If warranted as a result of conditions relating to a particular security, our Company will also review securities with declines in fair value resulting from a headline news event involving the issuer, a headline news event involving the asset class, the advice of our external asset managers, or economic events that may impact the issuer to determine if an unrealized loss is other-than-temporary.  The depth of analysis performed is dependent upon the nature and magnitude of the indicators of other-than-temporary impairment present in regards to each impaired security.

For equity securities, our Company performs a fundamental analysis of the issuer, including an evaluation of the mean analysts target price, to assess the likelihood of recovery of our cost basis in the security. Management also assesses the likelihood of future cash flows, dividends and increases to dividends, all of which affect the securities eligibility for our equity strategy and therefore our intent to hold the security.  If an equity security is deemed to be other-than-temporarily-impaired, the cost is written down to fair value with the cost recognized in earnings.

For fixed maturities, our Company assesses the underlying fundamentals of each issuer to determine if there is a change in the amount or timing of expected cash flows.  Management compares the amortized cost basis to the present value of the revised cash flows using the historical book yield to determine the credit loss portion of impairment which is recognized in earnings.  All non-credit losses where we have the intent and ability to hold the security until recovery are recognized as changes in OTTI losses within AOCI.

Specifically for structured fixed maturities, our Company analyzes 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.  For securities in which a tranche loss is present and the net present value of loss adjusted cash flows is less than book value, credit impairment is recognized in earnings. 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, which differ based on property type, vintage and the stress of the collateral.  

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.  

As of June 30, 2016, our Company does not intend to sell, and it is more-likely-than-not that it will not be required to sell any of its securities with unrealized losses before they recover in value.

Our Company had one credit related OTTI loss of $0.2 million in the Fixed maturities portfolio during the three and six months ended June 30, 2016.  Our Company had one credit related loss of $0.4 million in the equity portfolio during the three and six months ended June 30, 2015.

The following table summarizes the cumulative amounts related to our Company’s credit loss portion of the OTTI losses on Fixed maturities for the three and six months ended June 30, 2016 and 2015:

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 above, 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, 2016 and December 31, 2015:

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.  Under the terms of the agreement with the State, our Company was required to maintain an average of 100 full-time employees in Connecticut over a 12-month period in order for the State to forgive the initial $6.0 million of the loan.  In addition, as soon as our Company achieved a total of 150 full-time employees in Connecticut, we became eligible to receive an additional $1.0 million of the loan and $0.5 million of the grant.  On October 20, 2015, our Company received a letter from the State determining that we had achieved both of these milestones.  As a result, our Company earned a loan forgiveness credit of $6.0 million with the State and received the  additional $1.0 million of the loan and $0.5 million of the grant.  Earning of the remaining portions of the grant and forgiveness of any outstanding amounts of the loan is subject to certain conditions, including maintaining a certain number of required jobs for an extended period of time.  The length of time commitment for forgiveness of the additional $1.0 million of the October 20, 2015 loan has not yet been met. However, our Company expects to meet all the conditions for the State to forgive the loan. Accordingly, our Company is recognizing the amount of loan and grants received over the period in which offsetting expenses are recognized. Our Company recognized $0.4 million and $0.8 million of the incentive for the three and six months ended June 30, 2016. As of June 30, 2016 and December 31, 2015, our Company has deferred revenue of $5.5 million and $6.3 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 to the proceedings or directly as defendants.  Most of these proceedings consist of claims litigation involving our 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 effect on our Company’s Consolidated Statements of Income or Consolidated Statements of Cash Flows in a particular fiscal quarter or year.

Accounting Policies [Abstract]

Organization

Organization

We are an international insurance company with a long-standing area of specialization in Marine insurance.  We also offer Property and Casualty (“P&C”) insurance business, primarily 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 Directors & Officers (“D&O”) and Errors & Omissions (“E&O”) divisions.  Beginning in 2010, we added reinsurance products through our Global Reinsurance (“GlobalRe”) business.

We operate through various wholly-owned subsidiaries, including Navigators Insurance Company (“NIC”), inclusive of its United Kingdom Branch (“U.K. Branch”), and Navigators Specialty Insurance Company (“NSIC”), both of which are U.S. insurance companies, and Navigators Underwriting Agency Ltd. (“NUAL”), a Lloyd’s of London (“Lloyd’s”) underwriting agency that manages Lloyd’s Syndicate 1221 (the “Syndicate”) in the U.K. and is the primary underwriting company of Navigators Holdings (U.K.) Ltd. (“NHUK”), the holding company for our non U.S. domiciled entities. Our 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, 2015.  Certain amounts for the prior period have been reclassified to conform with the current period presentation.

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, 2016, we adopted the following accounting pronouncements, which did not have a material effect, singly or in the aggregate, on our consolidated financial condition, results of operations or cash flows:

· Accounting Standards Update 2015-03 – Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs, which is effective for fiscal years beginning after December 15, 2015. The new pronouncement was issued to simplify presentation of debt issuance costs.

The new pronouncement was issued to ensure that all investments categorized in the fair value hierarchy are classified using a consistent approach.

In 2016, 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 2016-01 – Financial Instruments (Subtopic 825-10) – Recognition and Measurement of Financial Assets and Financial Liabilities, which will be effective for fiscal years beginning after December 15, 2017.  The new pronouncement was issued to make targeted improvements to the presentation of financial instruments.

· Accounting Standards Update 2016-09 – Compensation – Stock Compensation – (Topic 718) - Improvements to Employee Share-Based Accounting, which will be effective for fiscal years beginning after December 15, 2016.  The new pronouncement was issued to simplify employee share-based accounting.

There were no additional 2016 accounting pronouncements that are expected to have an impact on the Consolidated Financial Statements upon adoption.
