NOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. Basis of Presentation

As used herein, the "Company,” “we,” “us,” or “our” refers to Selective Insurance Group, Inc. (the "Parent"), and its subsidiaries, except as expressly indicated or unless the context otherwise requires. Our interim unaudited consolidated financial statements (“Financial Statements”) have been prepared by us in conformity with U.S. generally accepted accounting principles (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The preparation of the Financial Statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported financial statement balances, as well as the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. All significant intercompany accounts and transactions between the Parent and its subsidiaries are eliminated in consolidation.

Certain amounts in our prior years' Financial Statements and related notes have been reclassified to conform to the 2016 presentation. Such reclassifications had no effect on our net income, stockholders' equity, or cash flows.

Our Financial Statements reflect all adjustments that, in our opinion, are normal, recurring, and necessary for a fair presentation of our results of operations and financial condition. Our Financial Statements cover the second quarters ended June 30, 2016 (“Second Quarter 2016”) and June 30, 2015 (“Second Quarter 2015”) and the six-month periods ended June 30, 2016 ("Six Months 2016") and June 30, 2015 ("Six Months 2015"). The Financial Statements do not include all of the information and disclosures required by GAAP and the SEC for audited annual financial statements. Results of operations for any interim period are not necessarily indicative of results for a full year. Consequently, our Financial Statements should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2015 (“2015 Annual Report”) filed with the SEC.

NOTE 2. Accounting Pronouncements 

In June 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (“ASU 2014-12”). ASU 2014-12 requires that performance targets that affect vesting and could be achieved after the requisite service period be treated as performance conditions. The adoption of ASU 2014-12 in the first quarter of 2016 did not affect us, as we record expense consistent with the requirements of this accounting update.

In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis (“ASU 2015-02”). ASU 2015-02 affects the following areas: (i) limited partnerships and similar legal entities; (ii) the evaluation of fees paid to a decision maker or a service provider as a variable interest; (iii) the effect of fee arrangements on the primary beneficiary determination; (iv) the effect of related parties on the primary beneficiary determination; and (v) certain investment funds. We adopted this guidance in the first quarter of 2016. Under the new guidance, our limited partnership and tax credit investments are variable interest entities ("VIEs"); however, we are not the primary beneficiary of any of these investments. As such, the adoption had no impact on our financial condition or results of operations. The required disclosures related to our VIEs are included in Note 4. “Investments” below.

In April 2015, the FASB issued ASU 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement (“ASU 2015-05”). ASU 2015-05 provides guidance to customers with cloud computing arrangements that include a software license. If a cloud computing arrangement includes a software license, the customer's accounting for the software license element of the arrangement is consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer accounts for the arrangement as a service contract. We adopted this guidance in the first quarter of 2016, with prospective application. The impact of this adoption did not have a material effect on our financial condition or results of operations.

In May 2015, the FASB issued ASU 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent) (“ASU 2015-07”). ASU 2015-07 provides that investments for which the practical expedient is used to measure fair value at net asset value per share ("NAV") must be removed from the fair value hierarchy. Instead, those investments must be included as a reconciling line item so that the total fair value amount of investments in the disclosure is consistent with the amount on the balance sheet. ASU 2015-07 also includes disclosure requirements for investments for which the NAV practical expedient was used to determine fair value. The adoption of this guidance in the first quarter of 2016 did not impact our financial condition or results of operations.

Pronouncements to be effective in the future

In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and provide related footnote disclosures. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early application is permitted. As the requirements of this literature are disclosure only, ASU 2014-15 will not impact our financial condition or results of operations.

In May 2015, the FASB issued ASU 2015-09, Disclosures about Short-Duration Contracts (“ASU 2015-09”). ASU 2015-09 requires companies that issue short duration contracts to disclose additional information, including: (i) incurred and paid claims development tables; (ii) frequency and severity of claims; and (iii) information about material changes in judgments made in calculating the liability for unpaid claim adjustment expenses, including reasons for the change and the effects on the financial statements. ASU 2015-09 is effective for annual periods beginning after December 15, 2015, and interim periods within annual periods beginning after December 15, 2016. ASU 2015-09 is to be applied retrospectively by providing comparative disclosures for each period presented, except for those requirements that apply only to the current period. As the requirements of this literature are disclosure only, the application of this guidance will not impact our financial condition or results of operations.

In January 2016, the FASB issued ASU 2016-01 Financial Instruments - Overall (Sub-topic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 provides guidance to improve certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Specifically the guidance: (i) requires equity investments to be measured at fair value with changes in fair value recognized in earnings; (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (iii) eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost; (iv) requires the use of the exit price notion when measuring the fair value of financial instruments for disclosure purposes; and (v) clarifies that the need for a valuation allowance on a deferred tax asset related to an available-for-sale ("AFS") security should be evaluated with other deferred tax assets.

ASU 2016-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early application to financial statements of annual or interim periods that have not yet been issued are permitted as of the beginning of the year of adoption, otherwise early adoption of ASU 2016-01 is not permitted. We are currently evaluating the impact of this guidance on our financial condition and results of operations.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that fiscal year, with early adoption permitted. ASU 2016-02 requires the application of a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. While we are currently evaluating ASU 2016-02, we do not expect a material impact on our financial condition or results of operations from the adoption of this guidance.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions including: (i) income tax consequences; (ii) classification of awards as either equity or liabilities; (iii) forfeitures assumptions; and (iv) cash flow classification. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. While we are currently evaluating ASU 2016-09, we do not expect a material impact on our financial condition or results of operations.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (“ASU 2016-13”).  ASU 2016-13 will change the way entities recognize impairment of financial assets by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, including, among others, held-to-maturity debt securities, trade receivables, and reinsurance receivables. ASU 2016-13 requires a valuation allowance to be calculated on these financial assets and that they be presented on the financial statements net of the valuation allowance. The valuation allowance is a measurement of expected losses that is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount.  This methodology is referred to as the current expected credit loss model. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted, but no earlier than fiscal years

beginning after December 15, 2018. We are currently evaluating the impact of this guidance on our financial condition and results of operations.

We do not intend to sell any of the securities in the tables above, nor do we believe we will be required to sell any of these securities. We have also reviewed these securities under our OTTI policy, as described in Note 2. “Summary of Significant Accounting Policies” within Item 8. “Financial Statements and Supplementary Data.” of our 2015 Annual Report, and have concluded that they are temporarily impaired. This conclusion reflects our current judgment as to the financial position and future prospects of the entity that issued the investment security and underlying collateral. If our judgment about an individual security changes in the future, we may ultimately record a credit loss after having originally concluded that one did not exist, which could have a material impact on our net income and financial position in future periods.

(d) Fixed income securities at June 30, 2016, by contractual maturity, are shown below. Mortgage-backed securities ("MBS") are included in the maturity tables using the estimated average life of each security. 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.

Listed below are the contractual maturities of HTM fixed income securities at June 30, 2016:

($ in thousands)	Carrying Value		Fair Value
Due in one year or less	$	84,415	85,514
Due after one year through five years	65,616		69,914
Due after five years through 10 years	10,266		11,633

Total AFS fixed income securities	$	4,671,786

(e) We evaluate the alternative investments and the tax credit investments that are included in our other investments portfolio to determine whether those investments are VIEs and if so, whether consolidation is required. A VIE is an entity that either has equity investors that lack certain essential characteristics of a controlling financial interest or lacks sufficient funds to finance its own activities without financial support provided by other entities. We consider several significant factors in determining if our investments are VIEs and if we are the primary beneficiary including whether we have: (i) the power to direct activities of the VIE; (ii) the ability to remove the decision maker of the VIE; (iii) the ability to participate in making decisions that are significant to the VIE; and (iv) the obligation to absorb losses and the right to receive benefits that could potentially be significant to the VIE. We have determined that the investments in our other investment portfolio are VIEs, but that we are not the primary beneficiary and therefore, consolidation is not required.

The following table summarizes our other investment portfolio by strategy:

Other Investments	June 30, 2016				December 31, 2015
($ in thousands)	Carrying Value		Remaining Commitment	Maximum Exposure to Loss1	Carrying Value	Remaining Commitment	Maximum Exposure to Loss1
Alternative Investments

Total other investments	$	76,051	94,483	170,534	77,842	74,353	152,195

¹The maximum exposure to loss includes both the carry value of these investments and the related unfunded commitments. In addition, tax credits that have been previously recognized from our investment in Other securities are subject to the risk of recapture, which we do not consider significant.

We do not have a future obligation to fund losses or debts on behalf of the investments above; however, we are contractually committed to make additional investments up to the remaining commitment outlined above. We have not provided any non-contractual financial support at any time during 2016 or 2015.

In addition to the strategy descriptions included in Note 5. “Investments” in Item 8. “Financial Statements and Supplementary Data.” of our 2015 Annual Report, our private credit strategy now includes middle market lending, which is a strategy that provides privately negotiated loans to U.S. middle market companies.  Typically, these are floating rate, senior secured loans diversified across industries.  Loans can be made to private equity sponsor-backed companies or non-sponsored companies to finance leveraged buyouts, recapitalizations, and acquisitions.

The following table sets forth gross summarized financial information for our other investments portfolio, including the portion not owned by us. The majority of these investments are carried under the equity method of accounting. The last line of the table below reflects our share of the aggregate loss, which is the portion included in our Financial Statements. As the majority of these investments report results to us on a one quarter lag, the summarized financial statement information for the three and six-month periods ended March 31 is as follows:

(f) We have pledged certain AFS fixed income securities as collateral related to our: (i) relationships with the Federal Home Loan Bank of Indianapolis ("FHLBI") and the Federal Home Loan Bank of New York ("FHLBNY"); and (ii) reinsurance obligations related to our 2011 acquisition of our excess and surplus lines ("E&S") book of business. In addition, certain securities were on deposit with various state and regulatory agencies at June 30, 2016 to comply with insurance laws. We retain all rights regarding all securities pledged as collateral.

Total net realized gains (excluding OTTI charges)	$	2,314		1,031		3,203		22,008

Realized gains and losses on the sale of investments are determined on the basis of the cost of the specific investments sold. Proceeds from the sale of AFS securities were $88.7 million and $19.5 million in Second Quarter 2016 and Second Quarter 2015, respectively, and $105.9 million and $157.9 million in Six Months 2016 and Six Months 2015, respectively. The $22.0 million in net realized gains for Six Months 2015 were primarily due to a change in our dividend equity strategy from a quantitative, model-driven stock selection strategy to a fundamentally-based stock selection approach that incorporates an assessment of the sustainability and growth rate of a company’s dividends and future cash flow.

NOTE 5. Indebtedness

During Six Months 2016, Selective Insurance Company of America ("SICA") borrowed the following short-term funds from the FHLBNY:

NOTE 8. Segment Information

We classify our business into four reportable segments, which are as follows:

• Standard Commercial Lines - comprised of insurance products and services provided in the standard marketplace to

commercial enterprises, which are typically businesses, non-profit organizations, and local government agencies.

• Standard Personal Lines - comprised of insurance products and services, including flood insurance coverage, provided primarily to individuals acquiring coverage in the standard marketplace.

• E&S Lines - comprised of insurance products and services provided to customers who have not obtained coverage in

the standard marketplace.

• Investments - invests the premiums collected by our insurance operations, as well as our earnings and amounts generated through our capital management strategies, which may include the issuance of debt and equity securities.

In computing the results of each segment, we do not make adjustments for interest expense or net general corporate expenses. While we do not fully allocate taxes to all segments, we do allocate taxes to our Investments segment as we manage that segment on after-tax results. We do not maintain separate investment portfolios for the segments and therefore, do not allocate assets to the segments.

NOTE 9. Retirement Plans

SICA's primary pension plan is the Retirement Income Plan for Selective Insurance Company of America (the “Pension Plan”). SICA also sponsors the Supplemental Excess Retirement Plan (the “Excess Plan”) and a life insurance benefit plan. All plans are closed to new entrants and benefits ceased accruing under the Pension Plan and the Excess Plan after March 31, 2016. For more information concerning SICA's retirement plans, refer to Note 14. “Retirement Plans” in Item 8. “Financial Statements and Supplementary Data.” of our 2015 Annual Report.

The following tables provide information regarding the Pension Plan:

Effective interest rate for calculation of interest cost	4.02		—
Expected return on plan assets	6.37		6.27
Rate of compensation increase	4.00		4.00

Effective January 1, 2016, the approach used to calculate the service and interest components of net periodic benefit cost for the Pension Plan was changed to provide a more precise measurement of these costs. Historically, we calculated the service and interest components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. On January 1, 2016, we elected to utilize an approach that discounts the individual expected cash flows using the applicable spot rates derived from the yield curve over the projected cash flow period. We accounted for this change prospectively as a change in accounting estimate. The decrease in service cost reflected in the table above is attributable to the discontinuation of benefit accruals for existing participants as of March 31, 2016. 

We presently anticipate contributing approximately $56 million to the Pension Plan in 2016, $26.4 million of which has been funded as of June 30, 2016.

NOTE 11. Litigation

In the ordinary course of conducting business, we are named as defendants in various legal proceedings. Most of these proceedings are claims litigation involving our insurance subsidiaries as either: (i) liability insurers defending or providing indemnity for third-party claims brought against our customers; or (ii) insurers defending first-party coverage claims brought against them. We account for such activity through the establishment of unpaid loss and loss expense reserves. We expect that the ultimate liability, if any, with respect to such ordinary course claims litigation, after consideration of provisions made for potential losses and costs of defense, will not be material to our consolidated financial condition, results of operations, or cash flows.

Our insurance subsidiaries are also from time to time involved in other legal actions, some of which assert claims for substantial amounts. These actions include, among others, putative class actions seeking certification of a state or national class. Such putative class actions have alleged, for example, improper reimbursement of medical providers paid under workers compensation and personal and commercial automobile insurance policies. Our insurance subsidiaries also are involved from time to time in individual actions in which extra-contractual damages, punitive damages, or penalties are sought, such as claims alleging bad faith in the handling of insurance claims. We believe that we have valid defenses to these cases. We expect that the ultimate liability, if any, with respect to such lawsuits, after consideration of provisions made for estimated losses, will not be material to our consolidated financial condition. Nonetheless, given the large or indeterminate amounts sought in certain of these actions, and the inherent unpredictability of litigation, an adverse outcome in certain matters could, from time to time, have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods. As of June 30, 2016, we do not believe the Company was involved in any legal action that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Forward-Looking Statements

As used herein, the "Company," "we," "us," or "our" refers to Selective Insurance Group, Inc. (the "Parent"), and its subsidiaries, except as expressly indicated or unless the context otherwise requires. In this Quarterly Report on Form 10-Q, we discuss and make statements regarding our intentions, beliefs, current expectations, and projections regarding our company’s future operations and performance. Such statements are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are often identified by words such as “anticipates,” “believes,” “expects,” “will,” “should,” and “intends” and their negatives. We caution prospective investors that such forward-looking statements are not guarantees of future performance. Risks and uncertainties are inherent in our future performance. Factors that could cause actual results to differ materially from those indicated by such forward-looking statements include, but are not limited to, those discussed under Item 1A. “Risk Factors” below in Part II “Other Information.” These risk factors may not be exhaustive. We operate in a continually changing business environment and new risk factors emerge from time to time. We can neither predict such new risk factors nor can we assess the impact, if any, of such new risk factors on our businesses or the extent to which any factor or combination of factors may cause actual results to differ materially from those expressed or implied in any forward-looking statements in this report. In light of these risks, uncertainties, and assumptions, the forward-looking events discussed in this report might not occur. We make forward-looking statements based on currently available information and assume no obligation to update these statements due to changes in underlying factors, new information, future developments, or otherwise.

Introduction

The Parent, through its insurance subsidiaries, offers property and casualty insurance products in the standard and excess and surplus ("E&S") marketplaces. We classify our business into four reportable segments, which are as follows:

• Standard Commercial Lines - which represents 79% of our combined insurance segments' net premiums written ("NPW"), sells commercial lines insurance products and services to businesses, non-profit organizations, and local government agencies located primarily in 22 states in the Eastern and Midwestern U.S. and the District of Columbia through approximately 1,150 distribution partners in the standard marketplace.

• Standard Personal Lines - which includes our flood business, represents approximately 12% of our combined insurance segments' NPW and sells personal lines insurance products and services to individuals located primarily in 13 states through approximately 700 distribution partners in the standard marketplace. In addition, we have approximately 5,000 distribution partners selling our flood business.

• E&S Lines - which represents 9% of our combined insurance segments' NPW, sells commercial lines insurance products and services in all 50 states and the District of Columbia through approximately 80 distribution partners. Insurance policies in this segment are sold to customers that typically have business risks with unique characteristics, such as the nature of the business or its claim history and cannot obtain coverage in the standard marketplace. E&S insurers have more flexibility in coverage terms and rates compared to standard market insurers, generally resulting in policies with higher rates and terms and conditions that are more narrowly customized for specific risks.

• Investments - invests the premiums collected by our Standard Commercial Lines, Standard Personal Lines, and E&S

Lines, as well as our earnings and amounts generated through our capital management strategies, which may include the issuance of debt and equity securities.

Our Standard Commercial and Standard Personal Lines products and services are written through our nine insurance subsidiaries, some of which write flood business through the Write Your Own ("WYO") program of the National Flood Insurance Program ("NFIP").

Our E&S products and services are written through one subsidiary, Mesa Underwriters Specialty Insurance Company ("MUSIC"). This subsidiary provides us with a nationally-authorized non-admitted platform to offer insurance products and services to customers who have not obtained coverage in the standard marketplace.

Our ten insurance subsidiaries are collectively referred to as the "Insurance Subsidiaries."

24

The following is Management’s Discussion and Analysis (“MD&A”) of the consolidated results of operations and financial condition, as well as known trends and uncertainties, that may have a material impact in future periods. Consequently, investors should read the MD&A in conjunction with the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2015 (“2015 Annual Report”) filed with the U.S. Securities and Exchange Commission ("SEC").

In the MD&A, we will discuss and analyze the following:

• Critical Accounting Policies and Estimates;

• Financial Highlights of Results for the second quarters ended June 30, 2016 (“Second Quarter 2016”) and June 30, 2015 (“Second Quarter 2015”) and the six-month periods ended June 30, 2016 ("Six Months 2016") and June 30, 2015 ("Six Months 2015");

• Results of Operations and Related Information by Segment;

• Federal Income Taxes;

• Financial Condition, Liquidity, Short-term Borrowings, and Capital Resources;

• Ratings;

• Off-Balance Sheet Arrangements; and

• Contractual Obligations, Contingent Liabilities, and Commitments.

Critical Accounting Policies and Estimates

Our unaudited interim consolidated financial statements include amounts based on our informed estimates and judgments for those transactions that are not yet complete. Such estimates and judgments affect the reported amounts in the consolidated financial statements. Those estimates and judgments most critical to the preparation of the consolidated financial statements involve the following: (i) reserves for loss and loss expenses; (ii) pension and post-retirement benefit plan actuarial assumptions; (iii) other-than-temporary investment impairments ("OTTI"); and (iv) reinsurance. These estimates and judgments require the use of assumptions about matters that are highly uncertain and, therefore, are subject to change as facts and circumstances develop. If different estimates and judgments had been applied, materially different amounts might have been reported in the financial statements. For additional information regarding our critical accounting policies, refer to pages 36 through 47 of our 2015 Annual Report.

¹  Refer to the Glossary of Terms attached to our 2015 Annual Report as Exhibit 99.1 for definitions of terms used in this Form 10-Q.

²  Operating income is used as an important financial measure by us, analysts, and investors, because the realization of investment gains and losses on sales in any given period is largely discretionary as to timing. In addition, these realized investment gains and losses, as well as OTTI that are charged to earnings and the results of discontinued operations, could distort the analysis of trends. See below for a reconciliation of operating income to net income in accordance with GAAP. Annualized operating ROE is calculated by dividing annualized operating income by average stockholders’ equity.

The following table reconciles operating income and net income for the periods presented above:

	Quarter ended June 30,				Six Months ended June 30,

It is our goal to average an operating ROE that is at least 300 basis points in excess of our weighted-average cost of capital. At June 30, 2016, our weighted-average cost of capital was 7.8%. Our ROE contributions by component are as follows:

ROE	Quarter ended June 30,				Six Months ended June 30,

Insurance Segments

The key metric in understanding our insurance segments’ contribution to annualized operating ROE is the GAAP combined ratio. The following table provides a quantitative foundation for analyzing this ratio:

The GAAP combined ratio improved by 2.3 points in both Second Quarter and Six Months 2016 compared to the same periods last year. This improvement was driven by the loss and loss expense ratio, reflecting lower catastrophe and non-catastrophe property losses, as last year was heavily impacted by severe winter weather and Midwest storms. Quantitative details are as follows:

	Second Quarter 2016				Second Quarter 2015
($ in millions)	Losses Incurred		Impact on Loss Ratio		Losses Incurred		Impact on  Loss Ratio		Change in Ratio
Catastrophe losses	$	8.4	1.6	pts	$	24.0	4.9	pts	(3.3	)	pts

Non-catastrophe property losses	130.8		12.4		141.5		14.6		(2.2	)

Partially offsetting these items was lower favorable prior year casualty reserve development, as illustrated in the table below:

For a qualitative discussion of this reserve development, please refer to the respective insurance segment section below in

"Results of Operations and Related Information by Segment."

Also impacting the GAAP combined ratio was an increase in the underwriting expense ratio that was driven by higher supplemental commission expense to our agents, due to improved profitability, which increased the ratio by 0.8 points in both Second Quarter and Six Months 2016 compared to the same periods last year.

Investments Segment

In total, our investment segment contributed 6.5 points to our overall annualized ROE in Second Quarter 2016, compared to 6.8 points in Second Quarter 2015, and 6.3 points in Six Months 2016, compared to 8.7 points in Six Months 2015. The primary driver of the 2.4-point decrease for the year-to-date period was a $16.4 million decrease in pre-tax net realized gains this year compared to last, the timing of which is largely subjective from one period to the next.

Outlook

A.M. Best Company, Inc. ("A.M. Best") projected a 2016 industry statutory combined ratio of 99.2% in their Review & Preview Report issued in February 2016. This projection included industry catastrophe losses of 4.7 points and favorable reserve development of 1.7 points. A.M. Best also projected decreasing investment yields to continue into 2016.

In 2016, we celebrated our 90^th year of business and our pillars of success continue to be: (i) our unique field model combined with sophisticated underwriting and claims capabilities; (ii) true franchise value with ourdistribution partners; and (iii) delivering a superior customer experience with our “best in class” employees. We plan to leverage our competitive advantages by increasing our share of wallet with existing agents while adding agents in areas with strong new business opportunities and exploring potential geographic expansion for our standard lines operations.

27

To that end, we remain focused on becoming a more customer-centric company in 2016. In 2015, we made key strategic investments in technology as part of our efforts to deliver a superior customer experience across all interactions. Over the last year, we have rolled out self-servicing capabilities via our mobile application, mobile web, and on the desktop, and relaunched our public website with simplified navigation, richer content, and responsive capabilities. These investments have enabled us to provide our customers with 24/7 access to transactional capabilities and information. We are also working to identify points of friction in the customer's experience between us and our distribution partners. These friction points provide opportunities for us to increase efficiency and improve the customer's impression of both us and our distribution partner. Customers expect this level of service and access from every company with which they conduct business. We view omni-channel service delivery as a key to future success in our industry and we will continue to focus our efforts in this area in 2016.

In Six Months 2016, our statutory combined ratio was 90.4%, which included 2.2 points of catastrophe losses and 2.6 points of favorable prior year casualty reserve development. Based on these results and our expectations for the remainder of the year, we are revising our guidance for full-year 2016 to the following:

• An ex-catastrophe combined ratio of approximately 89.5%, which is an improvement of 1.5 points from our previous guidance of 91%. This assumes no additional prior year casualty reserve development;

• 3.5 points of catastrophe losses;

• After-tax investment income of approximately $95 million; and

• Weighted average shares of approximately 58.5 million.

Our goal is to generate an operating ROE that is 300 basis points in excess of our weighted average cost of capital, which was 7.8% as of June 30, 2016. In Six Months 2016, our annualized operating ROE was 11.0%.

The increases in NPW in Second Quarter and Six Months 2016 compared to Second Quarter and Six Months 2015 were driven by: (i) increases in direct new business; (ii) renewal pure price increases; and (iii) strong retention.

The NPE increases in Second Quarter and Six Months 2016 compared to Second Quarter and Six Months 2015 were consistent with the fluctuation in NPW for the twelve-month period ended June 30, 2016 compared with the twelve-month period ended June 30, 2015.

The GAAP loss and loss expense ratio improved 1.8 points in Second Quarter 2016 compared to Second Quarter 2015 and 1.3 points in Six Months 2016 compared to Six Months 2015. These improvements were driven by lower catastrophe losses and non-catastrophe property losses, which were partially offset by lower favorable prior year casualty reserve development. Information regarding these drivers is as follows:

	Second Quarter 2016						Second Quarter 2015

The increases in the GAAP underwriting expense ratio in the quarter and year-to-date periods of 1.4 points and 1.5 points, respectively, were primarily attributable to higher supplemental commission expense to our distribution partners of approximately 1.0 points.

The statutory combined ratio increases in Second Quarter and Six Months 2016 compared to the same prior year periods were driven by lower favorable prior year casualty reserve development as illustrated in the tables below:

	Second Quarter 2016						Second Quarter 2015
($ in millions)	(Benefit) Expense			Impact on Combined Ratio			(Benefit) Expense			Impact on Combined Ratio			Change Points
Favorable prior year casualty reserve development	$	(11.0	)	(8.5	)	pts	$	(16.0	)	(13.4	)	pts	4.9	pts

Favorable prior year casualty reserve development	$	(22.0	)	(8.5	)	pts	$	(36.0	)	(15.4	)	pts	6.9	pts

The significant drivers of the development were as follows:

• Second Quarter and Six Months 2016: Development was primarily attributable to lower claims frequencies and severities in the 2012 through 2014 accident years.

• Second Quarter and Six Months 2015: Development was primarily attributable to continued lower claims frequencies in the 2009 through 2013 accident years.

The 6.4-point increase in the statutory combined ratio in Second Quarter 2016 compared to Second Quarter 2015 and the 6.0-point increase in the statutory combined ratio in Six Months 2016 compared to Six Months 2015 was primarily due to higher unfavorable prior year casualty reserve development.

Unfavorable prior year casualty reserve development in Second Quarter and Six Months 2016 was primarily due to higher claims frequencies in the 2015 accident year, as well as higher severities in the 2011 and 2013 accident years.

The decreases in the statutory combined ratio in Second Quarter and Six Months 2016 compared to the same prior year periods were due to the following:

• Favorable prior year casualty reserve development of $9.0 million, or 12.0 points, in Second Quarter 2016 related primarily to lower severities in accident years 2013 and prior, compared to $8.0 million, or 11.3 points, in Second Quarter 2015; and

• Favorable prior year casualty reserve development of $21.0 million, or 13.9 points, in Six Months 2016 related primarily to lower severities in accident years 2013 and prior, compared to $13.0 million, or 9.3 points, in Six Months 2015.

The 17.1-point decrease in the statutory combined ratio in Second Quarter 2016 compared to Second Quarter 2015 and the 12.1-point decrease in the statutory combined ratio in Six Months 2016 compared to Six Months 2015 were driven by: (i) lower catastrophe losses; and (ii) lower non-catastrophe property losses.

The decreases in NPW for the quarter and year-to-date periods were primarily driven by new business that were not sufficient to compensate for the attrition reflected in the 2016 retention ratios illustrated in the table below.

	Quarter ended June 30,				Six Months ended June 30,

The NPE decreases in Second Quarter and Six Months 2016 compared to Second Quarter and Six Months 2015 were consistent with the fluctuations in NPW for the twelve-month period ended June 30, 2016 compared with the twelve-month period ended June 30, 2015.

The GAAP loss and loss expense ratio decreased 15.2 points in Second Quarter 2016 compared to Second Quarter 2015 and 15.9 points in Six Months 2016 compared to Six Months 2015. The drivers of these fluctuations were as follows:

	Second Quarter 2016						Second Quarter 2015

The increase in the GAAP underwriting expense ratio in Six Months 2016 compared to Six Months 2015 was primarily driven by increased costs associated with: (i) capital technology improvements; and (ii) underwriting expenses from third-party data vendors.

The increases in NPW for both the quarter and year-to-date periods, compared to the same periods last year, were primarily driven by price increases of 4.8% and 4.1%, respectively, coupled with strong new business as indicated in the table below:

	Quarter ended June 30,			Six Months ended June 30,
($ in millions)	2016		2015	2016	2015
Direct new business	$	25.4	25.6	47.9	47.1

The NPE increases in Second Quarter and Six Months 2016, compared to Second Quarter and Six Months 2015, were consistent with the fluctuations in NPW for the twelve-month period ended June 30, 2016 compared with the twelve-month period ended June 30, 2015.

The GAAP loss and loss expense ratio increased by 2.4 points in Second Quarter 2016 and 1.8 points in Six Months 2016 compared to the same prior year periods. These variances reflect a 3.7-point increase in current year loss costs in both Second Quarter and Six Months 2016, as well as higher unfavorable prior year casualty reserve development. Quantitative information is as follows:

	Second Quarter 2016				Second Quarter 2015

33

The GAAP underwriting expense ratio decreased by 0.9 points in Second Quarter 2016 and 4.5 points in Six Months 2016, compared to the same prior year periods, primarily due to the following:

• A 0.7-point reduction in Second Quarter 2016 and 2.1-point reduction in Six Months 2016 from a lower annual cash incentive plan payment for employees in this segment based on 2015 underwriting results; and

• A 0.5-point decrease in Second Quarter 2016 and 1.2-point decrease in Six Months 2016 from lower commission expenses to our distribution partners reflecting a change in the mix of business written in this segment, as well as lower supplemental commission expense.

In addition, the growth in premiums earned in Second Quarter and Six Months 2016 compared to last year has more than outpaced the increase in fixed expenses, thus reducing the expense ratio.

Reinsurance

We have successfully completed negotiations of our July 1, 2016 excess of loss treaties, which continue to incorporate coverage for our Standard Commercial Lines, Standard Personal Lines, and E&S Lines. The renewal of these treaties included some enhancements in terms and conditions, with the same structure as the expiring treaties as follows:

Property Excess of Loss

The property excess of loss treaty ("Property Treaty") continues to provide $58.0 million of coverage in excess of a $2.0 million retention:

• The per occurrence cap on the first and second layers is $84.0 million.

• The first layer has unlimited reinstatements and a limit of $8.0 million in excess of $2.0 million.

• The annual aggregate limit for the $30.0 million in excess of $10.0 million second layer is $120.0 million.

• A third layer has a limit of $20.0 million excess of $40.0 million with an annual aggregate limit of approximately $70.0 million.

• The Property Treaty excludes nuclear, biological, chemical, and radiological ("NBCR") terrorism losses.

Casualty Excess of Loss

The casualty excess of loss treaty (“Casualty Treaty”) continues to provide $88.0 million of coverage in excess of a $2.0 million retention:

• The first through sixth layers provide coverage for 100% of up to $88.0 million in excess of a $2.0 million retention.

• The Casualty Treaty includes a $25.0 million limit, per life, on our workers compensation business, which is a $4.0 million increase from the prior treaty.

• The Casualty Treaty excludes NBCR terrorism losses and continues to have annual aggregate non-NBCR terrorism limits of $208.0 million.

Investments

Our investment philosophy includes certain return and risk objectives for the fixed income, equity, and other investment portfolios. Although yield and income generation remain the key drivers to our investment strategy, our overall philosophy is to invest with a long-term horizon along with predominantly a “buy-and-hold,” low turnover approach.

Total Invested Assets
($ in thousands)	June 30, 2016		December 31, 2015	Change % or Points
Total invested assets	$	5,266,523	5,089,269	3		%

Invested assets per dollar of stockholders' equity	3.39		3.64	(7	)
Annualized after-tax yield on investment portfolio	1.8		1.9	(0.1	)	pts

The increase in invested assets at June 30, 2016 compared to December 31, 2015 was driven by a $122.2 million increase in unrealized gains, primarily on our fixed income securities portfolio, as well as operating cash flow of $59.1 million. During Six Months 2016, interest rates on the 10-year U.S. Treasury Note fell by 80 basis points, which drove the increase in unrealized gains on the fixed income securities portfolio. While the low interest rate environment favorably impacts our unrealized position, it presents a challenge to us in generating after-tax return, as new purchase yields are below the average yield on bonds that are currently maturing.

34

Fixed Income Securities

At June 30, 2016, our fixed income securities portfolio represented 92% of our total invested assets, compared to our December 31, 2015 allocation of 91%. The average duration of the fixed income securities portfolio as of June 30, 2016 was 3.7 years, including short-term investments, compared to the Insurance Subsidiaries’ liability duration of approximately 4.3 years. The current duration of the fixed income securities portfolio is within our historical range, and is monitored and managed to maximize yield while managing interest rate risk at an acceptable level. We maintain a well-diversified portfolio across sectors, credit quality, and maturities that affords us ample liquidity. We typically have a long investment time horizon, and every purchase or sale is made with the intent of maximizing risk-adjusted investment returns in the current market environment while balancing capital preservation. Our fixed income securities portfolio had a weighted average credit rating of "AA-" as of both June 30, 2016 and December 31, 2015.

The sector composition and credit quality of our major asset categories within our fixed income securities portfolio did not significantly change from December 31, 2015. Our top 10 state exposures represented 53% of the total municipal bond portfolio as of June 30, 2016 and had an average rating of "AA." A portion of our municipal bond portfolio contains insurance enhancements; however, the ratings of the securities with and without insurance remained unchanged as we generally purchase securities based on their underlying credit quality. For details regarding this credit quality information, see Item 7A. “Quantitative and Qualitative Disclosures About Market Risk.” of our 2015 Annual Report.

Net Investment Income

The components of net investment income earned for the indicated periods were as follows:

Annualized after-tax yield on fixed income securities	2.0			2.1		2.0		2.1
Annualized after-tax yield on investment portfolio	1.8			2.0		1.8		1.9

Income on our fixed income securities portfolio increased in both Second Quarter and Six Months 2016, reflecting a higher asset base in this portfolio. However, losses on the alternative investments within our other investment portfolio more than offset this increase in Second Quarter 2016, resulting in a slight reduction in income compared to Second Quarter 2015.

Realized Gains and Losses

Our general philosophy for sales of securities is to reduce our exposure to securities and sectors based on economic evaluations and when the fundamentals for that security or sector have deteriorated, or to opportunistically trade out of securities to other securities with better economic return characteristics. Net realized gains for the indicated periods were as follows:

	Quarter ended June 30,					Six Months ended June 30,
($ in thousands)	2016			2015		2016		2015
Net realized gains, excluding OTTI	$	2.3		1.1		3.2		22.0
OTTI	(0.5		)	(4.5	)	(4.1	)	(6.5	)
Total net realized gains (losses)	1.8			(3.4	)	(0.9	)	15.5

Net realized gains excluding OTTI in Six Months 2015 reflect the sale of AFS equity securities related to a change in our dividend strategy from a quantitative, model-driven stock selection strategy to a fundamentally-based stock selection approach.

For further discussion of our realized gains and losses, as well as our OTTI methodology, see Note 2. “Summary of Significant Accounting Policies” in Item 8. “Financial Statements and Supplementary Data.” of our 2015 Annual Report. For additional information about our OTTI charges, see Note 4. "Investments" in Item 1. "Financial Statements." of this Form 10-Q.

Federal Income Taxes

The following table provides information regarding federal income taxes:

	Quarter ended June 30,				Six Months ended June 30,
($ in million)	2016			2015	2016	2015
Federal income tax expense	$	18.7		13.0	33.6	29.6
Effective tax rate	30		%	28	29	29

Federal income tax expense increased in Second Quarter and Six Months 2016 compared with the same prior year periods due to higher underwriting income. This increase in underwriting income was partially offset by a decrease in net realized gains in Six Months 2016 compared to Six Months 2015. The effective tax rate remained consistent with the comparable prior year periods, as tax-advantaged income remained flat compared to the increase in overall pre-tax income. The majority of our differences from the statutory rate are from recurring nontaxable items, such as tax-advantaged interest and dividends received deductions.

We believe that our future effective tax rate will continue to be impacted by similar items, assuming no significant changes to tax laws occur that would impact our tax-advantaged investments.

Financial Condition, Liquidity, Short-term Borrowings, and Capital Resources

Capital resources and liquidity reflect our ability to generate cash flows from business operations, borrow funds at competitive rates, and raise new capital to meet operating and growth needs.

Liquidity

We manage liquidity with a focus on generating sufficient cash flows to meet the short-term and long-term cash requirements of our business operations. Our cash and short-term investment position of $207 million at June 30, 2016 was comprised of $30 million at the Parent and $177 million at the Insurance Subsidiaries. Short-term investments are generally maintained in "AAA" rated money market funds approved by the National Association of Insurance Commissioners. The Parent maintains a fixed income security investment portfolio containing high-quality, highly-liquid government and corporate fixed income securities. This portfolio amounted to $63 million at June 30, 2016, consistent with December 31, 2015.

Sources of Liquidity

Sources of cash for the Parent have historically consisted of dividends from the Insurance Subsidiaries, the investment portfolio discussed above, borrowings under lines of credit and loan agreements with certain Insurance Subsidiaries, and the issuance of stock and debt securities. We continue to monitor these sources, giving consideration to our long-term liquidity and capital preservation strategies.

Insurance Subsidiary Dividends

We currently anticipate that the Insurance Subsidiaries will pay $61 million in total dividends to the Parent in 2016. Cash dividends of $31 million were paid during Six Months 2016. As of December 31, 2015, our allowable ordinary maximum dividend was $178 million for 2016.

Any dividends to the Parent are subject to the approval and/or review of the insurance regulators in the respective Insurance Subsidiaries' domiciliary states and are generally payable only from earned surplus as reported in the statutory annual statements of those subsidiaries as of the preceding December 31. Although past dividends have historically been met with regulatory approval, there is no assurance that future dividends that may be declared will be approved. Indiana state regulators passed legislation revising the calculation to determine an extraordinary dividend, which became effective on July 1, 2016. These changes did not have a material impact on our allowable ordinary dividends for 2016. For additional information regarding dividend restrictions, refer to Note 19. “Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds” in Item 8. “Financial Statements and Supplementary Data.” of our 2015 Annual Report.

The Insurance Subsidiaries generate liquidity through insurance float, which is created by collecting premiums and earning investment income before losses are paid. The period of the float can extend over many years. Our investment portfolio consists of maturity dates that continually provide a source of cash flows for claims payments in the ordinary course of business. The duration of the fixed income securities portfolio, including short-term investments, was 3.7 years as of June 30, 2016, while the liabilities of the Insurance Subsidiaries have a duration of 4.3 years. As protection for the capital resources at the Insurance Subsidiaries, we purchase reinsurance coverage for any significantly large claims or catastrophes that may occur during the year.

Line of Credit

The Parent's line of credit with Wells Fargo Bank, National Association, as administrative agent, and Branch Banking and Trust Company (BB&T) (referred to as our "Line of Credit"), was renewed effective December 1, 2015 with a borrowing capacity of $30 million, which can be increased to $50 million with the approval of both lending partners. This Line of Credit expires on December 1, 2020 and has an interest rate which varies and is based on, among other factors, the Parent's debt ratings.

The Line of Credit agreement contains representations, warranties, and covenants that are customary for credit facilities of this type, including, without limitation, financial covenants under which we are obligated to maintain a minimum consolidated net worth, a minimum combined statutory surplus, and a maximum ratio of consolidated debt to total capitalization, as well as covenants limiting our ability to: (i) merge or liquidate; (ii) incur debt or liens; (iii) dispose of assets; (iv) make certain investments and acquisitions; and (v) engage in transactions with affiliates.

The table below outlines information regarding certain of the covenants in the Line of Credit:

	Required as of June 30, 2016	Actual as of June 30, 2016
Consolidated net worth	$1.0 billion	$1.6 billion
Statutory surplus	Not less than $750 million	$1.5 billion
Debt-to-capitalization ratio1	Not to exceed 35%	20.4%
A.M. Best financial strength rating	Minimum of A-	A

¹  Calculated in accordance with the Line of Credit agreement.

Several of our Insurance Subsidiaries are members of certain branches of the Federal Home Loan Bank, which provides those subsidiaries with additional access to liquidity. Membership is as follows:

Branch	Insurance Subsidiary Member
Federal Home Loan Bank of Indianapolis ("FHLBI")	Selective Insurance Company of South Carolina ("SICSC")1 Selective Insurance Company of the Southeast ("SICSE")1
Federal Home Loan Bank of New York ("FHLBNY")	Selective Insurance Company of America ("SICA") Selective Insurance Company of New York ("SICNY")

¹These subsidiaries are jointly referred to as the "Indiana Subsidiaries" as they are domiciled in Indiana.

The Line of Credit permits aggregate borrowings from the FHLBI and the FHLBNY up to 10% of the respective member company’s admitted assets for the previous year. Additionally, the FHLBNY limits borrowings by SICA and SICNY to 5% of admitted assets for the previous year. All borrowings from both the FHLBI and the FHLBNY are required to be secured by investments pledged as collateral. For additional information regarding collateral outstanding, refer to Note 4. "Investments" in Item 1. "Financial Statements." of this Form 10-Q. The following table provides information on the remaining capacity for Federal Home Loan Bank borrowings based on these restrictions, as well as the amount of additional stock that would need to be purchased to allow these member companies to borrow their remaining capacity:

($ in millions)	Admitted Assets as of December 31, 2015		Borrowing Limitation		Amount Borrowed	Remaining Capacity	Additional Stock Requirements
As of June 30, 2016
SICSC1	$	594.3	$	59.4	32.0	27.4	1.2
SICSE1	461.8		46.2		28.0	18.2	0.8
SICA1	2,140.7		107.0		—	107.0	4.8
SICNY	403.4		20.2		—	20.2	0.9
Total			$	232.8	60.0	172.8	7.7

¹On July 21, 2016, SICA borrowed $25 million from the FHLBNY which is due in 2021. On July 22, 2016, SICSC and SICSE repaid $5 million and $10 million, respectively, on their borrowing from the FHLBI.

37

Intercompany Loan Agreements

The Parent has lending agreements with the Indiana Subsidiaries that have been approved by the Indiana Department of Insurance, which provide additional liquidity to the Parent. Similar to the Line of Credit agreement, these lending agreements limit borrowings by the Parent from the Indiana Subsidiaries to 10% of the admitted assets of the respective Indiana Subsidiary. The following table provides information on the Parent’s borrowings and remaining borrowing capacity from the Indiana Subsidiaries:

($ in millions)	Admitted Assets as of December 31, 2015		Borrowing Limitation		Amount Borrowed	Remaining Capacity
As of June 30, 2016
SICSC	$	594.3	$	59.4	29.7	29.7
SICSE	461.8		46.2		18.3	27.9
Total			$	105.6	48.0	57.6

Capital Market Activities

The Parent had no private or public issuances of stock or debt instruments during Six Months 2016.

Uses of Liquidity

The liquidity generated from the sources discussed above is used, among other things, to pay dividends to our shareholders. Dividends on shares of the Parent's common stock are declared and paid at the discretion of the Board of Directors based on our operating results, financial condition, capital requirements, contractual restrictions, and other relevant factors.

Our ability to meet our interest and principal repayment obligations on our debt, as well as our ability to continue to pay dividends to our stockholders, is dependent on liquidity at the Parent coupled with the ability of the Insurance Subsidiaries to pay dividends, if necessary, and/or the availability of other sources of liquidity to the Parent. Scheduled repayments of our FHLBI borrowings are $15 million, which was paid in July 2016 and $45 million, which is due in December 2016. Subsequent to these payments, our next principal repayment is due in 2021, which is the FHLBNY borrowing made in July 2016.

Restrictions on the ability of the Insurance Subsidiaries to declare and pay dividends, without alternative liquidity options, could materially affect our ability to service debt and pay dividends on common stock.

Short-term Borrowings

There were no balances outstanding under the Line of Credit at June 30, 2016 or at any time during 2016. In Six Months 2016, SICA borrowed an aggregate amount of $55 million through three short-term borrowings from FHLBNY. None of these borrowings remained outstanding at June 30, 2016. For additional information regarding these and other borrowings, see Note 5. "Indebtedness" in Item 1. "Financial Statements." of this Form 10-Q.

Capital Resources

Capital resources provide protection for policyholders, furnish the financial strength to support the business of underwriting insurance risks, and facilitate continued business growth. At June 30, 2016, we had statutory surplus of $1.5 billion and GAAP stockholders’ equity of $1.6 billion. With total debt of $388 million, our debt-to-capital ratio was approximately 20%.

Our cash requirements include, but are not limited to, principal and interest payments on various notes payable, dividends to stockholders, payment of claims, payment of commitments under limited partnership agreements and capital expenditures, as well as other operating expenses, which include commissions to our distribution partners, labor costs, premium taxes, general and administrative expenses, and income taxes. For further details regarding our cash requirements, refer to the section below entitled, “Contractual Obligations, Contingent Liabilities, and Commitments.”

We continually monitor our cash requirements and the amount of capital resources that we maintain at the holding company and operating subsidiary levels. As part of our long-term capital strategy, we strive to maintain capital metrics, relative to the macroeconomic environment, that support our targeted financial strength. Based on our analysis and market conditions, we may take a variety of actions, including, but not limited to, contributing capital to the Insurance Subsidiaries in our insurance operations, issuing additional debt and/or equity securities, repurchasing shares of the Parent’s common stock, and increasing stockholders’ dividends.

38

Our capital management strategy is intended to protect the interests of the policyholders of the Insurance Subsidiaries and our stockholders, while enhancing our financial strength and underwriting capacity.

Book value per share increased to $26.86 as of June 30, 2016, up from $24.37 as of December 31, 2015, due to $1.38 in net income and $1.37 in unrealized gains on our investment portfolio, partially offset by $0.30 in dividends to our shareholders.

Ratings

We are rated by major rating agencies that issue opinions on our financial strength, operating performance, strategic position, and ability to meet policyholder obligations. We believe that our ability to write insurance business is most influenced by our rating from A.M. Best. We have been rated “A” or higher by A.M. Best for the past 86 years. A downgrade from A.M. Best to a rating below “A-” is an event of default under our Line of Credit and could affect our ability to write new business with customers and/or distribution partners, some of whom are required (under various third-party agreements) to maintain insurance with a carrier that maintains a specified A.M. Best minimum rating.

Our ratings have not changed from those reported in our "Ratings" section of Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations." in our 2015 Annual Report and continue to be as follows:

NRSRO	Financial Strength Rating	Outlook
A.M. Best	A	Stable
Standard & Poor's Rating Services	A-	Positive
Moody's Investor Services	A2	Stable
Fitch Ratings	A+	Stable

Our S&P, Moody's, and Fitch financial strength and associated credit ratings affect our ability to access capital markets.  The interest rate on our Line of Credit varies and is based on, among other factors, the Parent's debt ratings. There can be no assurance that our ratings will continue for any given period of time or that they will not be changed.  It is possible that positive or negative ratings actions by one or more of the rating agencies may occur in the future.

Off-Balance Sheet Arrangements

At June 30, 2016 and December 31, 2015, we did not have any material relationships with unconsolidated entities or financial partnerships, also referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or for other contractually narrow or limited purposes. As such, we are not exposed to any material financing, liquidity, market, or credit risk that could arise if we had engaged in such relationships.

Contractual Obligations, Contingent Liabilities, and Commitments

Our future cash payments associated with: (i) loss and loss expense reserves; (ii) contractual obligations pursuant to operating leases for office space and equipment; (iii) notes payable; and (iv) contractual obligations related to our alternative and other investments portfolio have not materially changed since December 31, 2015. Additionally, as of June 30, 2016, we had contractual obligations that expire in 2019 to invest $15 million in a non-publicly traded common stock within our AFS portfolio. We expect to have the capacity to repay and/or refinance these obligations as they come due.

We have issued no material guarantees on behalf of others and have no trading activities involving non-exchange traded contracts accounted for at fair value. We have no material transactions with related parties other than those disclosed in Note 16. "Related Party Transactions" included in Item 8. "Financial Statements and Supplementary Data." of our 2015 Annual Report.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

There have been no material changes in the information about market risk set forth in our 2015 Annual Report.

ITEM 4.   CONTROLS AND PROCEDURES.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”)), as of the end of the period covered by this report. In performing this evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework ("COSO Framework")in 2013. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures are: (i) effective in recording, processing, summarizing, and reporting information on a timely basis that we are required to disclose in the reports that we file or submit under the Exchange Act; and (ii) effective in ensuring that information that we are required to disclose in the reports that we file or submit under the Exchange Act is accumulated and

39

communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. No changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act) occurred during Six Months 2016 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

In the ordinary course of conducting business, we are named as defendants in various legal proceedings. Most of these proceedings are claims litigation involving our Insurance Subsidiaries as either: (i) liability insurers defending or providing indemnity for third-party claims brought against our customers; or (ii) insurers defending first-party coverage claims brought against them. We account for such activity through the establishment of unpaid loss and loss expense reserves. We expect that the ultimate liability, if any, with respect to such ordinary course claims litigation, after consideration of provisions made for potential losses and costs of defense, will not be material to our consolidated financial condition, results of operations, or cash flows.

Our Insurance Subsidiaries are also from time to time involved in other legal actions, some of which assert claims for substantial amounts. These actions include, among others, putative class actions seeking certification of a state or national class. Such putative class actions have alleged, for example, improper reimbursement of medical providers paid under workers compensation and personal and commercial automobile insurance policies. Our Insurance Subsidiaries are also involved from time to time in individual actions in which extra-contractual damages, punitive damages, or penalties are sought, such as claims alleging bad faith in the handling of insurance claims. We believe that we have valid defenses to these cases. We expect that the ultimate liability, if any, with respect to such lawsuits, after consideration of provisions made for estimated losses, will not be material to our consolidated financial condition. Nonetheless, given the large or indeterminate amounts sought in certain of these actions, and the inherent unpredictability of litigation, an adverse outcome in certain matters could, from time to time, have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods. As of June 30, 2016, we do not believe the Company was involved in any legal action that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

ITEM 1A. RISK FACTORS.

Certain risk factors exist that can have a significant impact on our business, liquidity, capital resources, results of operations, financial condition, and debt ratings. The impact of these risk factors also could impact certain actions that we take as part of our long-term capital strategy, including but not limited to, contributing capital to any or all of the Insurance Subsidiaries, issuing additional debt and/or equity securities, repurchasing our equity securities, redeeming our fixed income securities, or increasing or decreasing stockholders dividends. We operate in a continually changing business environment and new risk factors emerge from time to time. Consequently, we can neither predict such new risk factors nor assess the potential future impact, if any, they might have on our business. There have been no material changes from the risk factors disclosed in Item 1A. “Risk Factors.” in our 2015 Annual Report.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS.

The following table provides information regarding our purchases of our common stock in Second Quarter 2016:

Period	Total Number of Shares Purchased1	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Programs	Maximum Number of Shares that May Yet Be Purchased Under the Announced Programs
April 1 – 30, 2016	3,826	$	35.78	—	—

June 1 - 30, 2016	985	37.30		—	—
Total	15,757	$	36.40	—	—

¹During Second Quarter 2016, 4,811 shares were purchased from employees in connection with the vesting of restricted stock units and 10,946 shares were purchased from employees in connection with option exercises. These repurchases were made to satisfy tax withholding obligations and/or option costs with respect to those employees. These shares were not purchased as part of any publicly announced program. The shares that were purchased in connection with the vesting of restricted stock units were purchased at fair market value as defined in the Selective Insurance Group, Inc. 2014 Omnibus Stock Plan and the Selective Insurance Group, Inc. 2005 Omnibus Stock Plan As Amended and Restated Effective as of May 1, 2010. The shares purchased in connection with the option exercises were purchased at the current market prices of our common stock on the dates the options were exercised.

Basis of Presentation And Significant Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

As used herein, the "Company,” “we,” “us,” or “our” refers to Selective Insurance Group, Inc. (the "Parent"), and its subsidiaries, except as expressly indicated or unless the context otherwise requires. Our interim unaudited consolidated financial statements (“Financial Statements”) have been prepared by us in conformity with U.S. generally accepted accounting principles (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The preparation of the Financial Statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported financial statement balances, as well as the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. All significant intercompany accounts and transactions between the Parent and its subsidiaries are eliminated in consolidation.

Certain amounts in our prior years' Financial Statements and related notes have been reclassified to conform to the 2016 presentation. Such reclassifications had no effect on our net income, stockholders' equity, or cash flows.

Our Financial Statements reflect all adjustments that, in our opinion, are normal, recurring, and necessary for a fair presentation of our results of operations and financial condition. Our Financial Statements cover the second quarters ended June 30, 2016 (“Second Quarter 2016”) and June 30, 2015 (“Second Quarter 2015”) and the six-month periods ended June 30, 2016 ("Six Months 2016") and June 30, 2015 ("Six Months 2015"). The Financial Statements do not include all of the information and disclosures required by GAAP and the SEC for audited annual financial statements. Results of operations for any interim period are not necessarily indicative of results for a full year. Consequently, our Financial Statements should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2015 (“2015 Annual Report”) filed with the SEC.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Accounting Pronouncements

Accounting Pronouncements 

In June 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (“ASU 2014-12”). ASU 2014-12 requires that performance targets that affect vesting and could be achieved after the requisite service period be treated as performance conditions. The adoption of ASU 2014-12 in the first quarter of 2016 did not affect us, as we record expense consistent with the requirements of this accounting update.

In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis (“ASU 2015-02”). ASU 2015-02 affects the following areas: (i) limited partnerships and similar legal entities; (ii) the evaluation of fees paid to a decision maker or a service provider as a variable interest; (iii) the effect of fee arrangements on the primary beneficiary determination; (iv) the effect of related parties on the primary beneficiary determination; and (v) certain investment funds. We adopted this guidance in the first quarter of 2016. Under the new guidance, our limited partnership and tax credit investments are variable interest entities ("VIEs"); however, we are not the primary beneficiary of any of these investments. As such, the adoption had no impact on our financial condition or results of operations. The required disclosures related to our VIEs are included in Note 4. “Investments” below.

In April 2015, the FASB issued ASU 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement (“ASU 2015-05”). ASU 2015-05 provides guidance to customers with cloud computing arrangements that include a software license. If a cloud computing arrangement includes a software license, the customer's accounting for the software license element of the arrangement is consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer accounts for the arrangement as a service contract. We adopted this guidance in the first quarter of 2016, with prospective application. The impact of this adoption did not have a material effect on our financial condition or results of operations.

In May 2015, the FASB issued ASU 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent) (“ASU 2015-07”). ASU 2015-07 provides that investments for which the practical expedient is used to measure fair value at net asset value per share ("NAV") must be removed from the fair value hierarchy. Instead, those investments must be included as a reconciling line item so that the total fair value amount of investments in the disclosure is consistent with the amount on the balance sheet. ASU 2015-07 also includes disclosure requirements for investments for which the NAV practical expedient was used to determine fair value. The adoption of this guidance in the first quarter of 2016 did not impact our financial condition or results of operations.

Pronouncements to be effective in the future

In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and provide related footnote disclosures. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early application is permitted. As the requirements of this literature are disclosure only, ASU 2014-15 will not impact our financial condition or results of operations.

In May 2015, the FASB issued ASU 2015-09, Disclosures about Short-Duration Contracts (“ASU 2015-09”). ASU 2015-09 requires companies that issue short duration contracts to disclose additional information, including: (i) incurred and paid claims development tables; (ii) frequency and severity of claims; and (iii) information about material changes in judgments made in calculating the liability for unpaid claim adjustment expenses, including reasons for the change and the effects on the financial statements. ASU 2015-09 is effective for annual periods beginning after December 15, 2015, and interim periods within annual periods beginning after December 15, 2016. ASU 2015-09 is to be applied retrospectively by providing comparative disclosures for each period presented, except for those requirements that apply only to the current period. As the requirements of this literature are disclosure only, the application of this guidance will not impact our financial condition or results of operations.

In January 2016, the FASB issued ASU 2016-01 Financial Instruments - Overall (Sub-topic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 provides guidance to improve certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Specifically the guidance: (i) requires equity investments to be measured at fair value with changes in fair value recognized in earnings; (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (iii) eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost; (iv) requires the use of the exit price notion when measuring the fair value of financial instruments for disclosure purposes; and (v) clarifies that the need for a valuation allowance on a deferred tax asset related to an available-for-sale ("AFS") security should be evaluated with other deferred tax assets.

ASU 2016-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early application to financial statements of annual or interim periods that have not yet been issued are permitted as of the beginning of the year of adoption, otherwise early adoption of ASU 2016-01 is not permitted. We are currently evaluating the impact of this guidance on our financial condition and results of operations.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that fiscal year, with early adoption permitted. ASU 2016-02 requires the application of a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. While we are currently evaluating ASU 2016-02, we do not expect a material impact on our financial condition or results of operations from the adoption of this guidance.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions including: (i) income tax consequences; (ii) classification of awards as either equity or liabilities; (iii) forfeitures assumptions; and (iv) cash flow classification. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. While we are currently evaluating ASU 2016-09, we do not expect a material impact on our financial condition or results of operations.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (“ASU 2016-13”).  ASU 2016-13 will change the way entities recognize impairment of financial assets by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, including, among others, held-to-maturity debt securities, trade receivables, and reinsurance receivables. ASU 2016-13 requires a valuation allowance to be calculated on these financial assets and that they be presented on the financial statements net of the valuation allowance. The valuation allowance is a measurement of expected losses that is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount.  This methodology is referred to as the current expected credit loss model. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2018. We are currently evaluating the impact of this guidance on our financial condition and results of operations.

Unrealized gains and losses of AFS securities represent fair value fluctuations from the later of: (i) the date a security is designated as AFS; or (ii) the date that an OTTI charge is recognized on an AFS security, through the date of the balance sheet. These unrealized gains and losses are recorded in Accumulated other comprehensive income (loss) ("AOCI") on the Consolidated Balance Sheets.

 ¹ Gross unrealized losses include non-OTTI unrealized amounts and OTTI losses recognized in AOCI.  In addition, this column includes remaining unrealized gain or loss amounts on securities that were transferred to an HTM designation in the first quarter of 2009 for those securities that are in a net unrealized/unrecognized loss position.

There were no net unrealized/unrecognized losses on our HTM portfolio as of June 30, 2016. The table below provides our net unrealized/unrecognized loss positions by impairment severity for AFS securities as of June 30, 2016 and for both AFS and HTM securities as of December 31, 2015:

We do not intend to sell any of the securities in the tables above, nor do we believe we will be required to sell any of these securities. We have also reviewed these securities under our OTTI policy, as described in Note 2. “Summary of Significant Accounting Policies” within Item 8. “Financial Statements and Supplementary Data.” of our 2015 Annual Report, and have concluded that they are temporarily impaired. This conclusion reflects our current judgment as to the financial position and future prospects of the entity that issued the investment security and underlying collateral. If our judgment about an individual security changes in the future, we may ultimately record a credit loss after having originally concluded that one did not exist, which could have a material impact on our net income and financial position in future periods.

(d) Fixed income securities at June 30, 2016, by contractual maturity, are shown below. Mortgage-backed securities ("MBS") are included in the maturity tables using the estimated average life of each security. 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.

Listed below are the contractual maturities of HTM fixed income securities at June 30, 2016:

($ in thousands)	Carrying Value		Fair Value
Due in one year or less	$	84,415	85,514
Due after one year through five years	65,616		69,914
Due after five years through 10 years	10,266		11,633

Due after one year through five years	2,425,517
Due after five years through 10 years	1,647,615

Total AFS fixed income securities	$	4,671,786

(e) We evaluate the alternative investments and the tax credit investments that are included in our other investments portfolio to determine whether those investments are VIEs and if so, whether consolidation is required. A VIE is an entity that either has equity investors that lack certain essential characteristics of a controlling financial interest or lacks sufficient funds to finance its own activities without financial support provided by other entities. We consider several significant factors in determining if our investments are VIEs and if we are the primary beneficiary including whether we have: (i) the power to direct activities of the VIE; (ii) the ability to remove the decision maker of the VIE; (iii) the ability to participate in making decisions that are significant to the VIE; and (iv) the obligation to absorb losses and the right to receive benefits that could potentially be significant to the VIE. We have determined that the investments in our other investment portfolio are VIEs, but that we are not the primary beneficiary and therefore, consolidation is not required.

The following table summarizes our other investment portfolio by strategy:

Other Investments	June 30, 2016				December 31, 2015
($ in thousands)	Carrying Value		Remaining Commitment	Maximum Exposure to Loss1	Carrying Value	Remaining Commitment	Maximum Exposure to Loss1
Alternative Investments
Private equity	$	28,439	34,117	62,556	35,088	30,204	65,292
Private credit	23,336		23,243	46,579	13,246	15,129	28,375
Real assets	14,132		30,273	44,405	19,500	25,820	45,320

Total other investments	$	76,051	94,483	170,534	77,842	74,353	152,195

¹The maximum exposure to loss includes both the carry value of these investments and the related unfunded commitments. In addition, tax credits that have been previously recognized from our investment in Other securities are subject to the risk of recapture, which we do not consider significant. 

We do not have a future obligation to fund losses or debts on behalf of the investments above; however, we are contractually committed to make additional investments up to the remaining commitment outlined above. We have not provided any non-contractual financial support at any time during 2016 or 2015.

In addition to the strategy descriptions included in Note 5. “Investments” in Item 8. “Financial Statements and Supplementary Data.” of our 2015 Annual Report, our private credit strategy now includes middle market lending, which is a strategy that provides privately negotiated loans to U.S. middle market companies.  Typically, these are floating rate, senior secured loans diversified across industries.  Loans can be made to private equity sponsor-backed companies or non-sponsored companies to finance leveraged buyouts, recapitalizations, and acquisitions.

The following table sets forth gross summarized financial information for our other investments portfolio, including the portion not owned by us. The majority of these investments are carried under the equity method of accounting. The last line of the table below reflects our share of the aggregate loss, which is the portion included in our Financial Statements. As the majority of these investments report results to us on a one quarter lag, the summarized financial statement information for the three and six-month periods ended March 31 is as follows:

(f) We have pledged certain AFS fixed income securities as collateral related to our: (i) relationships with the Federal Home Loan Bank of Indianapolis ("FHLBI") and the Federal Home Loan Bank of New York ("FHLBNY"); and (ii) reinsurance obligations related to our 2011 acquisition of our excess and surplus lines ("E&S") book of business. In addition, certain securities were on deposit with various state and regulatory agencies at June 30, 2016 to comply with insurance laws. We retain all rights regarding all securities pledged as collateral.

The following table summarizes the market value of these securities at June 30, 2016:

Total net realized gains (excluding OTTI charges)	$	2,314		1,031		3,203		22,008

Realized gains and losses on the sale of investments are determined on the basis of the cost of the specific investments sold. Proceeds from the sale of AFS securities were $88.7 million and $19.5 million in Second Quarter 2016 and Second Quarter 2015, respectively, and $105.9 million and $157.9 million in Six Months 2016 and Six Months 2015, respectively. The $22.0 million in net realized gains for Six Months 2015 were primarily due to a change in our dividend equity strategy from a quantitative, model-driven stock selection strategy to a fundamentally-based stock selection approach that incorporates an assessment of the sustainability and growth rate of a company’s dividends and future cash flow.

Segment Reporting [Abstract]

Segment Information

Segment Information

We classify our business into four reportable segments, which are as follows:

• Standard Commercial Lines - comprised of insurance products and services provided in the standard marketplace to

commercial enterprises, which are typically businesses, non-profit organizations, and local government agencies.

• Standard Personal Lines - comprised of insurance products and services, including flood insurance coverage, provided primarily to individuals acquiring coverage in the standard marketplace.

• E&S Lines - comprised of insurance products and services provided to customers who have not obtained coverage in

the standard marketplace.

• Investments - invests the premiums collected by our insurance operations, as well as our earnings and amounts generated through our capital management strategies, which may include the issuance of debt and equity securities.

In computing the results of each segment, we do not make adjustments for interest expense or net general corporate expenses. While we do not fully allocate taxes to all segments, we do allocate taxes to our Investments segment as we manage that segment on after-tax results. We do not maintain separate investment portfolios for the segments and therefore, do not allocate assets to the segments.

The following summaries present revenues (net investment income and net realized gains on investments in the case of the Investments segment) and pre-tax income for the individual segments:

Retirement Plans

Retirement Plans

SICA's primary pension plan is the Retirement Income Plan for Selective Insurance Company of America (the “Pension Plan”). SICA also sponsors the Supplemental Excess Retirement Plan (the “Excess Plan”) and a life insurance benefit plan. All plans are closed to new entrants and benefits ceased accruing under the Pension Plan and the Excess Plan after March 31, 2016. For more information concerning SICA's retirement plans, refer to Note 14. “Retirement Plans” in Item 8. “Financial Statements and Supplementary Data.” of our 2015 Annual Report.

The following tables provide information regarding the Pension Plan:

Effective interest rate for calculation of interest cost	4.02		—
Expected return on plan assets	6.37		6.27
Rate of compensation increase	4.00		4.00

Effective January 1, 2016, the approach used to calculate the service and interest components of net periodic benefit cost for the Pension Plan was changed to provide a more precise measurement of these costs. Historically, we calculated the service and interest components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. On January 1, 2016, we elected to utilize an approach that discounts the individual expected cash flows using the applicable spot rates derived from the yield curve over the projected cash flow period. We accounted for this change prospectively as a change in accounting estimate. The decrease in service cost reflected in the table above is attributable to the discontinuation of benefit accruals for existing participants as of March 31, 2016. 

We presently anticipate contributing approximately $56 million to the Pension Plan in 2016, $26.4 million of which has been funded as of June 30, 2016.

Loss Contingency, Information about Litigation Matters [Abstract]

Litigation

Litigation

In the ordinary course of conducting business, we are named as defendants in various legal proceedings. Most of these proceedings are claims litigation involving our insurance subsidiaries as either: (i) liability insurers defending or providing indemnity for third-party claims brought against our customers; or (ii) insurers defending first-party coverage claims brought against them. We account for such activity through the establishment of unpaid loss and loss expense reserves. We expect that the ultimate liability, if any, with respect to such ordinary course claims litigation, after consideration of provisions made for potential losses and costs of defense, will not be material to our consolidated financial condition, results of operations, or cash flows.

Our insurance subsidiaries are also from time to time involved in other legal actions, some of which assert claims for substantial amounts. These actions include, among others, putative class actions seeking certification of a state or national class. Such putative class actions have alleged, for example, improper reimbursement of medical providers paid under workers compensation and personal and commercial automobile insurance policies. Our insurance subsidiaries also are involved from time to time in individual actions in which extra-contractual damages, punitive damages, or penalties are sought, such as claims alleging bad faith in the handling of insurance claims. We believe that we have valid defenses to these cases. We expect that the ultimate liability, if any, with respect to such lawsuits, after consideration of provisions made for estimated losses, will not be material to our consolidated financial condition. Nonetheless, given the large or indeterminate amounts sought in certain of these actions, and the inherent unpredictability of litigation, an adverse outcome in certain matters could, from time to time, have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods. As of June 30, 2016, we do not believe the Company was involved in any legal action that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.
