Summary of Significant Accounting Policies	Summary of Significant Accounting Policies A. Basis of Financial Statement Presentation The accompanying unaudited consolidated financial statements include the accounts of Provident Financial Services, Inc. and its wholly owned subsidiary, The Provident Bank (the “Bank,” together with Provident Financial Services, Inc., the “Company”). In preparing the interim unaudited consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the statements of financial condition and the results of operations for the periods presented. Actual results could differ from these estimates. The allowance for loan losses, the valuation of securities available for sale and the valuation of deferred tax assets are material estimates that are particularly susceptible to near-term change. The interim unaudited consolidated financial statements reflect all normal and recurring adjustments, which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. The results of operations for the three and nine months ended September 30, 2015 are not necessarily indicative of the results of operations that may be expected for all of 2015 . Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. These unaudited consolidated financial statements should be read in conjunction with the December 31, 2014 Annual Report to Stockholders on Form 10-K. B. Earnings Per Share The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share calculations for the three and nine months ended September 30, 2015 and 2014 (dollars in thousands, except per share amounts): Three months ended September 30, 2015 2014 Net Income Weighted Average Common Shares Outstanding Per Share Amount Net Income Weighted Average Common Shares Outstanding Per Share Amount Net income $ 20,609 $ 19,032 Basic earnings per share: Income available to common stockholders $ 20,609 63,034,185 $ 0.33 $ 19,032 62,440,310 $ 0.30 Dilutive shares 164,114 118,897 Diluted earnings per share: Income available to common stockholders $ 20,609 63,198,299 $ 0.33 $ 19,032 62,559,207 $ 0.30 Nine months ended September 30, 2015 2014 Net Weighted Per Net Weighted Per Net income $ 62,207 $ 52,412 Basic earnings per share: Income available to common stockholders $ 62,207 62,868,745 $ 0.99 $ 52,412 59,670,773 $ 0.88 Dilutive shares 160,644 133,432 Diluted earnings per share: Income available to common stockholders $ 62,207 63,029,389 $ 0.99 $ 52,412 59,804,205 $ 0.88 Anti-dilutive stock options and awards at September 30, 2015 and 2014 , totaling 518,433 shares and 1,099,371 shares, respectively, were excluded from the earnings per share calculations.

Business Combinations [Abstract]
Business Combinations	Business Combinations On April 1, 2015, Beacon Trust Company ("Beacon"), a wholly owned subsidiary of The Provident Bank, completed its acquisition of The MDE Group, Inc. and the equity interests of Acertus Capital Management, LLC (together "MDE"), both Morristown, New Jersey-based registered investment advisory firms that manage assets for affluent and high net-worth clients and their financial advisors. MDE was acquired with both cash and contingent consideration. The Company recognized goodwill of $20.1 million and a customer relationship intangible of $7.0 million related to the acquisition. The Company recognized a contingent consideration liability at its fair value of $2.0 million . The contingent consideration arrangement requires the Company to pay additional cash consideration to MDE’s former stakeholders four years after the closing of the acquisition if certain revenue targets are met. The fair value of the contingent consideration was estimated using a discounted cash flow model. The acquisition agreement limits the total payment to a maximum of $12.5 million , to be determined based on actual future results. On October 31, 2014, Beacon acquired the fiduciary account relationships of Suffolk County National Bank, a subsidiary of Suffolk Bancorp, in Suffolk County, New York. On May 30, 2014, the Company completed its acquisition of Team Capital Bank ("Team Capital"), which after purchase accounting adjustments added $964.0 million to total assets, $631.2 million to loans, and $769.9 million to deposits. Total consideration paid for Team Capital was $115.1 million : $31.6 million in cash and 4.9 million shares of common stock valued at $83.5 million on the acquisition date. Team Capital was merged with and into the Company's subsidiary, The Provident Bank as of the close of business on the date of acquisition. The Team Capital transaction was accounted for under the acquisition method of accounting. Under this method of accounting, the purchase price has been allocated to the respective assets acquired and liabilities assumed based upon their estimated fair values, net of tax. The excess of consideration paid over the fair value of the net assets acquired has been recorded as goodwill. The following table summarizes the estimated fair values of the assets acquired and the liabilities assumed at the date of acquisition from Team Capital, net of cash consideration paid (in thousands): At May 30, 2014 Assets acquired: Cash and cash equivalents, net $ 68,650 Securities available for sale 157,635 Loans 631,209 Bank-owned life insurance 22,319 Banking premises and equipment 24,778 Accrued interest receivable 3,060 Goodwill 40,897 Other intangibles assets 9,868 Foreclosed assets, net 653 Other assets 4,905 Total assets acquired 963,974 Liabilities assumed: Deposits 769,936 Borrowed Funds 112,835 Other liabilities (2,314 ) Total liabilities assumed 880,457 Net assets acquired $ 83,517 Upon the completion and filing of the Team Capital short-period tax return for the period ended May 30, 2014, a net operating loss carryback claim was filed with the Internal Revenue Service to reclaim taxes previously paid by Team Capital in the prior two years. As a result of the claim process, the Company determined that the tax receivable established by Team Capital at the May 30, 2014 acquisition date was overstated by $543,000 . In May 2015, the Company decreased the tax receivable recorded at the date of acquisition by $543,000 , along with a corresponding increase to goodwill. The purchase accounting for the Team Capital transaction is complete, and is reflected in both the table above and the Company's Consolidated Financial Statements. Fair Value Measurement of Assets Assumed and Liabilities Assumed The methods used to determine the fair value of the assets acquired and liabilities assumed in the Team Capital acquisition were as follows: Securities Available for Sale The estimated fair values of the investment securities classified as available for sale were calculated utilizing Level 1 and Level 2 inputs. Management reviewed the data and assumptions used by its third-party provider in pricing the securities to ensure the highest level of significant inputs is derived from observable market data. These prices were validated against other pricing sources and broker-dealer indications. Loans The acquired loan portfolio was valued based on current guidance which defines fair value as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Level 3 inputs were utilized to value the portfolio and included the use of present value techniques employing cash flow estimates and the incorporated assumptions that marketplace participants would use in estimating fair values. In instances where reliable market information was not available, the Company used its own assumptions in an effort to determine reasonable fair value. Specifically, Management utilized three separate fair value analyses which a market participant would employ in estimating the total fair value adjustment. The three separate fair valuation methodologies used were: 1) interest rate loan fair value analysis; 2) general credit fair value adjustment; and 3) specific credit fair value adjustment. To prepare the interest rate fair value analysis, loans were grouped by characteristics such as loan type, term, collateral and rate. Market rates for similar loans were obtained from various external data sources and reviewed by Company management for reasonableness. The average of these rates was used as the fair value interest rate a market participant would utilize. A present value approach was utilized to calculate the interest rate fair value adjustment. The general credit fair value adjustment was calculated using a two part general credit fair value analysis: (1) expected lifetime losses; and (2) estimated fair value adjustment for qualitative factors. The expected lifetime losses were calculated using an average of historical losses of the Company, the acquired bank and peer banks. The adjustment related to qualitative factors was impacted by general economic conditions and the risk related to lack of familiarity with the originator's underwriting process. To calculate the specific credit fair value adjustment, management reviewed the acquired loan portfolio for loans meeting the definition of an impaired loan with deteriorated credit quality. Loans meeting this definition were reviewed by comparing the contractual cash flows to expected collectible cash flows. The aggregate expected cash flows less the acquisition date fair value resulted in an accretable yield amount. The accretable yield amount will be recognized over the life of the loans on a level yield basis as an adjustment to yield. Deposits and Core Deposit Premium Core deposit premium represents the value assigned to demand, interest checking, money market and savings accounts acquired as part of an acquisition. The core deposit premium value represents the future economic benefit, including the present value of future tax benefits, of the potential cost savings from acquiring core deposits as part of an acquisition compared to the cost alternative funding sources and was valued utilizing Level 2 inputs. Time deposits are not considered to be core deposits as they are assumed to have a low expected average life upon acquisition. The fair value of time deposits represents the present value of the expected contractual payments discounted by market rates for similar time deposits and was valued utilizing Level 2 inputs. Borrowed Funds The fair value for borrowed funds was obtained from actual prepayment rates from the Federal Home Loan Bank ("FHLB") of Pittsburgh, a Level 2 input. These borrowings were redeemed after the acquisition date and the fair value adjustment was fully amortized in the quarter ended June 30, 2014.

Investment Securities	Investment Securities At September 30, 2015 , the Company had $ 994.8 million and $471.7 million in available for sale and held to maturity investment securities, respectively. Many factors, including lack of liquidity in the secondary market for certain securities, variations in pricing information, regulatory actions, changes in the business environment or any changes in the competitive marketplace could have an adverse effect on the Company’s investment portfolio which could result in other-than-temporary impairment on certain investment securities in future periods. The total number of held to maturity and available for sale securities in an unrealized loss position as of September 30, 2015 totaled 163 , compared with 206 at December 31, 2014 . All securities with unrealized losses at September 30, 2015 were analyzed for other-than-temporary impairment. Based upon this analysis, the Company believes that as of September 30, 2015 , such securities with unrealized losses do not represent impairments that are other-than-temporary. Securities Available for Sale The following tables present the amortized cost, gross unrealized gains, gross unrealized losses and the fair value for securities available for sale at September 30, 2015 and December 31, 2014 (in thousands): September 30, 2015 Amortized cost Gross unrealized gains Gross unrealized losses Fair value US Treasury obligations $ 8,008 61 — 8,069 Agency obligations 87,488 386 — 87,874 Mortgage-backed securities 871,044 16,262 (497 ) 886,809 State and municipal obligations 5,916 89 — 6,005 Corporate obligations 5,517 16 (17 ) 5,516 Equity securities 397 101 — 498 $ 978,370 16,915 (514 ) 994,771 December 31, 2014 Amortized Gross Gross Fair US Treasury obligations $ 8,016 3 (3 ) 8,016 Agency Obligations 94,871 268 (63 ) 95,076 Mortgage-backed securities 944,796 15,610 (3,149 ) 957,257 State and municipal obligations 6,855 147 — 7,002 Corporate obligations 6,526 9 (15 ) 6,520 Equity securities 397 127 — 524 $ 1,061,461 16,164 (3,230 ) 1,074,395 The amortized cost and fair value of securities available for sale at September 30, 2015 , by contractual maturity, are shown below (in thousands). Expected maturities may differ from contractual maturities due to prepayment or early call privileges of the issuer. September 30, 2015 Amortized cost Fair value Due in one year or less $ 20,680 20,695 Due after one year through five years 80,278 80,738 Due after five years through ten years 3,683 3,693 Due after ten years 2,288 2,338 $ 106,929 107,464 Mortgage-backed securities totaling $871.0 million at amortized cost and $886.8 million at fair value are excluded from the table above as their expected lives are likely to be shorter than the contractual maturity date due to principal prepayments. Also excluded from the table above are equity securities of $ 397,000 at amortized cost and $ 498,000 at fair value. During the three months ended September 30, 2015 , there were no sales of securities from the securities available for sale. For the same period last year, proceeds from the sale of securities available for sale were $ 9,946,000 resulting in gross gains of $ 482,000 and no gross losses. For the nine months ended September 30, 2015 , proceeds from the sale of securities available for sale were $14,005,000 , resulting in gross gains of $643,000 and no gross losses. For the same period last year, proceeds from the sale of securities available for sale were $24,429,000 , resulting in gross gains of $632,000 and gross losses of $404,000 . Also, for the nine months ended September 30, 2015 , proceeds from calls of securities available for sale totaled $465,000 , resulting in gross gains of $2,000 gains and no gross losses. For the nine months ended September 30, 2014 , proceeds from calls on securities available for sale totaled $740,000 , resulting in gross gains of $2,000 and no gross losses. The following table presents a roll-forward of the credit loss component of other-than-temporary impairment (“OTTI”) on debt securities for which a non-credit component of OTTI was recognized in other comprehensive income. OTTI recognized in earnings for credit-impaired debt securities is presented in two components based upon whether the current period is the first time a debt security was credit-impaired (initial credit impairment), or whether the current period is not the first time a debt security was credit-impaired (subsequent credit impairment). Changes in the credit loss component of credit-impaired debt securities were as follows (in thousands): Three months ended September 30, Nine months ended September 30, 2015 2014 2015 2014 Beginning credit loss amount $ — — — 1,674 Add: Initial OTTI credit losses — — — — Subsequent OTTI credit losses — — — — Less: Realized losses for securities sold — — — 1,674 Securities intended or required to be sold — — — — Increases in expected cash flows on debt securities — — — — Ending credit loss amount $ — — — — The Company did not incur an OTTI charge on securities for the three and nine months ended September 30, 2015 and 2014 . For the three and nine months ended September 30, 2014 , the Company realized a $59,000 gain and a $365,000 loss on the sales of previously impaired non-agency mortgage-backed securities, respectively. The Company previously incurred cumulative credit losses of $1.7 million on these securities. The following tables represent the Company’s disclosure regarding securities available for sale with temporary impairment at September 30, 2015 and December 31, 2014 (in thousands): September 30, 2015 Unrealized Losses Less than 12 months 12 months or longer Total Fair value Gross unrealized losses Fair value Gross unrealized losses Fair value Gross unrealized losses Agency obligations — — — — — — Mortgage-backed securities 47,521 (162 ) 50,441 (335 ) 97,962 (497 ) State and municipal obligations — — — — — — Corporate obligations 1,464 (7 ) 993 (10 ) 2,457 (17 ) $ 48,985 (169 ) 51,434 (345 ) 100,419 (514 ) December 31, 2014 Unrealized Losses Less than 12 months 12 months or longer Total Fair value Gross unrealized losses Fair value Gross unrealized losses Fair value Gross unrealized losses U.S. Treasury obligations $ 5,937 (3 ) — — 5,937 (3 ) Agency obligations 24,404 (40 ) 5,010 (23 ) 29,414 (63 ) Mortgage-backed securities 55,488 (221 ) 206,669 (2,928 ) 262,157 (3,149 ) Corporate obligations 3,466 (15 ) — — 3,466 (15 ) $ 89,295 (279 ) 211,679 (2,951 ) 300,974 (3,230 ) The temporary loss position associated with certain securities available for sale was the result of changes in market interest rates relative to the coupon of the individual security and changes in credit spreads. The Company does not have the intent to sell securities in a temporary loss position at September 30, 2015 , nor is it more likely than not that the Company will be required to sell the securities before their prices recover. The number of available for sale securities in an unrealized loss position at September 30, 2015 totaled 16 , compared with 43 at December 31, 2014 . At September 30, 2015 , there were three private label mortgage-backed securities in an unrealized loss position, with an amortized cost of $943,000 and an unrealized loss of $7,000 . These private label mortgage-backed securities were investment grade at September 30, 2015 . The Company estimates the loss projections for each security by stressing the individual loans collateralizing the security and applying a range of expected default rates, loss severities, and prepayment speeds in conjunction with the underlying credit enhancement for each security. Based on specific assumptions about collateral and vintage, a range of possible cash flows was identified to determine whether other-than-temporary impairment existed during the three and nine months ended September 30, 2015 . The Company believes that no other-than-temporary impairment of the securities available for sale portfolio existed for the three and nine months ended September 30, 2015 . Investment Securities Held to Maturity The following tables present the amortized cost, gross unrealized gains, gross unrealized losses and the estimated fair value for investment securities held to maturity at September 30, 2015 and December 31, 2014 (in thousands): September 30, 2015 Amortized cost Gross unrealized gains Gross unrealized losses Fair value Agency obligations $ 5,195 15 (1 ) 5,209 Mortgage-backed securities 1,821 78 — 1,899 State and municipal obligations 454,446 11,870 (1,213 ) 465,103 Corporate obligations 10,261 32 (9 ) 10,284 $ 471,723 11,995 (1,223 ) 482,495 December 31, 2014 Amortized cost Gross unrealized gains Gross unrealized losses Fair value Agency obligations $ 6,813 17 (20 ) 6,810 Mortgage-backed securities 2,816 123 — 2,939 State and municipal obligations 449,410 13,814 (986 ) 462,238 Corporate obligations 10,489 29 (32 ) 10,486 $ 469,528 13,983 (1,038 ) 482,473 The Company generally purchases securities for long-term investment purposes, and differences between amortized cost and fair values may fluctuate during the investment period. For the three and nine months ended September 30, 2015 , the Company recognized gross gains of $5,000 and no gross losses, respectively, related to calls of certain securities in the held to maturity portfolio, with proceeds from the calls totaling $7,984,000 and $21,204,000 for the three and nine months ended September 30, 2015 , respectively. There were no sales of securities from the held to maturity portfolio for the three and nine months ended September 30, 2015 . For the three and nine months ended September 30, 2014 , the Company recognized gross gains of $5,000 and $20,000 , and no gross losses, respectively, related to calls of certain securities in the held to maturity portfolio, with proceeds from the calls totaling $3,566,000 and $12,376,000 , respectively. In addition, for the three and nine months ended September 30, 2014 , the Company recognized a gross loss of $3,000 , and no gross gain, related to the sale of a security in the held to maturity portfolio, with the proceeds from the sale totaling $524,000 . The sale of this security was in response to credit deterioration of the issuer. The amortized cost and fair value of investment securities in the held to maturity portfolio at September 30, 2015 by contractual maturity are shown below (in thousands). Expected maturities may differ from contractual maturities due to prepayment or early call privileges of the issuer. September 30, 2015 Amortized cost Fair value Due in one year or less $ 8,385 8,456 Due after one year through five years 53,201 54,296 Due after five years through ten years 214,416 221,661 Due after ten years 193,900 196,183 $ 469,902 480,596 Mortgage-backed securities totaling $ 1.8 million at amortized cost and $ 1.9 million at fair value are excluded from the table above as their expected lives are likely to be shorter than the contractual maturity date due to principal prepayments. The following tables represent the Company’s disclosure on investment securities held to maturity with temporary impairment at September 30, 2015 and December 31, 2014 (in thousands): September 30, 2015 Unrealized Losses Less than 12 months 12 months or longer Total Fair value Gross unrealized losses Fair value Gross unrealized losses Fair value Gross unrealized losses Agency obligations $ — — 280 (1 ) 280 (1 ) State and municipal obligations 61,156 (690 ) 19,244 (523 ) 80,400 (1,213 ) Corporate obligations 1,711 (7 ) 499 (2 ) 2,210 (9 ) $ 62,867 (697 ) 20,023 (526 ) 82,890 (1,223 ) December 31, 2014 Unrealized Losses Less than 12 months 12 months or longer Total Fair Gross Fair Gross Fair Gross Agency obligations $ 3,735 (20 ) — — 3,735 (20 ) State and municipal obligations 27,679 (217 ) 47,079 (769 ) 74,758 (986 ) Corporate obligations 6,888 (32 ) — — 6,888 (32 ) $ 38,302 (269 ) 47,079 (769 ) 85,381 (1,038 ) Based upon the review of the held to maturity securities portfolio, the Company believes that as of September 30, 2015 , securities with unrealized loss positions shown above do not represent impairments that are other-than-temporary. The review of the portfolio for other-than-temporary impairment considers the percentage and length of time the fair value of an investment is below book value, as well as general market conditions, changes in interest rates, credit risks, whether the Company has the intent to sell the securities and whether it is more likely than not that the Company would be required to sell the securities before their prices recover. The number of held to maturity securities in an unrealized loss position at September 30, 2015 totaled 147 , compared with 163 at December 31, 2014 . The decrease in the number of securities in an unrealized loss position at September 30, 2015 , was largely due to a decrease in market interest rates from December 31, 2014 . All temporarily impaired investment securities were investment grade at September 30, 2015 .

The principal amounts of these non-accrual loans were $39.6 million and $53.9 million at September 30, 2015 and December 31, 2014 , respectively. Included in non-accrual loans were $15.9 million and $8.4 million of loans which were less than 90 days past due at September 30, 2015 and December 31, 2014 , respectively. There were no loans 90 days or greater past due and still accruing interest at September 30, 2015 , or December 31, 2014 . The Company defines an impaired loan as a non-homogeneous loan greater than $1.0 million for which it is probable, based on current information, all amounts due under the contractual terms of the loan agreement will not be collected. Impaired loans also include all loans modified as troubled debt restructurings (“TDRs”). A loan is deemed to be a TDR when a loan modification resulting in a concession is made in an effort to mitigate potential loss arising from a borrower’s financial difficulty. Smaller balance homogeneous loans, including residential mortgages and other consumer loans, are evaluated collectively for impairment and are excluded from the definition of impaired loans, unless modified as TDRs. The Company separately calculates the reserve for loan losses on impaired loans. The Company may recognize impairment of a loan based upon: (1) the present value of expected cash flows discounted at the effective interest rate; (2) if a loan is collateral dependent, the fair value of collateral; or (3) the fair value of the loan. Additionally, if impaired loans have risk characteristics in common, those loans may be aggregated and historical statistics may be used as a means of measuring those impaired loans. The Company uses third-party appraisals to determine the fair value of the underlying collateral in its analyses of collateral dependent impaired loans. A third-party appraisal is generally ordered as soon as a loan is designated as a collateral dependent impaired loan and is updated annually or more frequently, if required. A specific allocation of the allowance for loan losses is established for each collateral dependent impaired loan with a carrying balance greater than the collateral’s fair value, less estimated costs to sell. Charge-offs are generally taken for the amount of the specific allocation when operations associated with the respective property cease and it is determined that collection of amounts due will be derived primarily from the disposition of the collateral. At each quarter end, if a loan is designated as a collateral dependent impaired loan and the third party appraisal has not yet been received, an evaluation of all available collateral is made using the best information available at the time, including rent rolls, borrower financial statements and tax returns, prior appraisals, management’s knowledge of the market and collateral, and internally prepared collateral valuations based upon market assumptions regarding vacancy and capitalization rates, each as and where applicable. Once the appraisal is received and reviewed, the specific reserves are adjusted to reflect the appraised value. The Company believes there have been no significant time lapses as a result of this process. At September 30, 2015 , there were 148 impaired loans totaling $67.9 million . Included in this total were 123 TDRs related to 121 borrowers totaling $47.9 million that were performing in accordance with their restructured terms and which continued to accrue interest at September 30, 2015 . At December 31, 2014 , there were 147 impaired loans totaling $85.4 million . Included in this total were 123 TDRs to 120 borrowers totaling $54.8 million that were performing in accordance with their restructured terms and which continued to accrue interest at December 31, 2014 . The following table summarizes loans receivable by portfolio segment and impairment method, excluding PCI loans (in thousands): September 30, 2015 Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Individually evaluated for impairment $ 48,809 16,678 2,402 67,889 Collectively evaluated for impairment 4,479,589 1,307,566 573,312 6,360,467 Total gross loans $ 4,528,398 1,324,244 575,714 6,428,356 December 31, 2014 Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Individually evaluated for impairment $ 66,548 16,463 2,384 85,395 Collectively evaluated for impairment 4,141,940 1,245,959 609,083 5,996,982 Total gross loans $ 4,208,488 1,262,422 611,467 6,082,377 The allowance for loan losses is summarized by portfolio segment and impairment classification as follows (in thousands): September 30, 2015 Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Unallocated Total Individually evaluated for impairment $ 2,184 91 106 2,381 — 2,381 Collectively evaluated for impairment 29,438 24,985 3,633 58,056 27 58,083 Total gross loans $ 31,622 25,076 3,739 60,437 27 60,464 December 31, 2014 Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Unallocated Total Individually evaluated for impairment $ 4,696 2,318 113 7,127 — 7,127 Collectively evaluated for impairment 27,281 22,063 4,768 54,112 495 54,607 Total gross loans $ 31,977 24,381 4,881 61,239 495 61,734 Loan modifications to borrowers experiencing financial difficulties that are considered TDRs primarily involve lowering the monthly payments on such loans through either a reduction in interest rate below a market rate, an extension of the term of the loan without a corresponding adjustment to the risk premium reflected in the interest rate, or a combination of these two methods. These modifications generally do not result in the forgiveness of principal or accrued interest. In addition, the Company attempts to obtain additional collateral or guarantor support when modifying such loans. If the borrower has demonstrated performance under the previous terms and our underwriting process shows the borrower has the capacity to continue to perform under the restructured terms, the loan will continue to accrue interest. Non-accruing restructured loans may be returned to accrual status when there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. The following tables present the number of loans modified as TDRs during the three and nine months ended September 30, 2015 and 2014 and their balances immediately prior to the modification date and post-modification as of September 30, 2015 and 2014 : For the three months ended September 30, 2015 September 30, 2014 Troubled Debt Restructuring Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment ($ in thousands) Mortgage loans: Residential 1 $ 258 $ 256 4 $ 742 $ 774 Total mortgage loans 1 258 256 4 742 774 Commercial loans — — — 1 — 367 Consumer loans — — — 2 393 165 Total restructured loans 1 $ 258 $ 256 7 $ 1,135 $ 1,306 For the nine months ended September 30, 2015 September 30, 2014 Troubled Debt Restructuring Number of Pre-Modification Post-Modification Number of Pre-Modification Post-Modification ($ in thousands) Mortgage loans: Residential 6 $ 2,192 2,184 12 $ 2,705 $ 2,443 Commercial — — — 1 865 866 Construction 1 2,600 2,096 Total mortgage loans 7 4,792 4,280 13 3,570 3,309 Commercial loans 4 6,659 6,903 2 300 665 Consumer loans 2 123 115 2 393 165 Total restructured loans 13 $ 11,574 $ 11,298 17 $ 4,263 $ 4,139 All TDRs are impaired loans, which are individually evaluated for impairment, as previously discussed. Estimated collateral values of collateral dependent impaired loans modified during the three and nine months ended September 30, 2015 and 2014 exceeded the carrying amounts of such loans. There were charge-offs recorded on two collateral dependent impaired loans of $312,000 for the three and nine months ended September 30, 2015 , which are included in the preceding tables. There were no charge-offs recorded on collateral dependent impaired loans for 2014 . The allowance for loan losses associated with the TDRs presented in the preceding tables totaled $0 and $117,000 for the three months ended September 30, 2015 and 2014 , respectively, and were included in the allowance for loan losses for loans individually evaluated for impairment. For the nine months ended September 30, 2015 and 2014 , the allowance for loan losses associated with the TDRs presented in the preceding tables totaled $82,000 and $426,000 , respectively, and were included in the allowance for loan losses for loans individually evaluated for impairment. For the three and nine months ended September 30, 2015 , the TDRs presented in the preceding tables had a weighted average modified interest rate of approximately 3.00% and 5.26% , respectively, compared to a rate of 3.00% and 5.71% prior to modification, respectively. For the three and nine months ended September 30, 2014 , the TDRs had weighted average modified interest rate of approximately 5.50% and 4.90% , respectively, compared to a rate of 6.50% and 5.70% prior to modification, respectively. There were no payment defaults (90 days or more past due) at the quarter ended September 30, 2015 and 2014 related to loans modified as TDRs within the previous 12 months from September 30, 2015 and 2014. TDRs that subsequently default are considered collateral dependent impaired loans and are evaluated for impairment based on the estimated fair value of the underlying collateral less expected selling costs. PCI loans are loans acquired at a discount primarily due to deteriorated credit quality. As part of the Team Capital acquisition, $5.2 million of the loans purchased at May 30, 2014 were determined to be PCI loans. At the date of acquistion, PCI loans were accounted for at fair value, based upon the present value of expected future cash flows, with no related allowance for loan losses. The following table presents information regarding the estimates of the contractually required payments, the cash flows expected to be collected and the estimated fair value of the PCI loans acquired from Team Capital at May 30, 2014 (in thousands): May 30, 2014 Contractually required principal and interest $ 12,505 Contractual cash flows not expected to be collected (non-accretable discount) (6,475 ) Expected cash flows to be collected at acquisition 6,030 Interest component of expected cash flows (accretable yield) (810 ) Fair value of acquired loans $ 5,220 PCI loans declined $839,000 to $3.7 million at September 30, 2015 , from $4.5 million at December 31, 2014, largely due to the full repayment and greater than projected cash flows on certain PCI loans. This resulted in a $129,000 and a $349,000 increase in interest income for the three and nine months ended September 30, 2015 , due to the acceleration of accretable and non-accretable discount on these loans. The following table summarizes the changes in the accretable yield for PCI loans during the three and nine months ended September 30, 2015 (in thousands): Three months ended Sept 30, Nine months ended Sept 30, 2015 2014 2015 2014 Beginning balance $ 609 $ 773 $ 695 $ — Acquisition — — — 810 Accretion (220 ) (314 ) (683 ) (351 ) Reclassification from non-accretable discount 172 136 549 136 Ending balance $ 561 $ 595 $ 561 $ 595 The activity in the allowance for loan losses by portfolio segment for the three and nine months ended September 30, 2015 and 2014 was as follows (in thousands): Three months ended September 30, Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Unallocated Total 2015 Balance at beginning of period $ 31,824 22,840 4,570 59,234 390 59,624 Provision charged to operations 569 1,604 (411 ) 1,762 (362 ) 1,400 Recoveries of loans previously charged-off 3 762 352 1,117 — 1,117 Loans charged-off (774 ) (130 ) (772 ) (1,676 ) (1 ) (1,677 ) Balance at end of period $ 31,622 25,076 3,739 60,437 27 60,464 2014 Balance at beginning of period $ 31,040 27,079 4,381 62,500 1,375 63,875 Provision charged to operations 54 1,114 442 1,610 (110 ) 1,500 Recoveries of loans previously charged-off 120 404 172 696 — 696 Loans charged-off (538 ) (1,755 ) (448 ) (2,741 ) — (2,741 ) Balance at end of period $ 30,676 26,842 4,547 62,065 1,265 63,330 Nine months ended September 30, Mortgage Commercial Consumer Total Portfolio Unallocated Total 2015 Balance at beginning of period $ 31,977 24,381 4,881 61,239 495 61,734 Provision charged to operations 1,924 926 718 3,568 (468 ) 3,100 Recoveries of loans previously charged-off 139 1,636 819 2,594 — 2,594 Loans charged-off (2,418 ) (1,867 ) (2,679 ) (6,964 ) — (6,964 ) Balance at end of period $ 31,622 25,076 3,739 60,437 27 60,464 2014 Balance at beginning of period $ 34,144 24,107 4,929 63,180 1,484 64,664 Provision charged to operations (1,300 ) 4,108 811 3,619 (219 ) 3,400 Recoveries of loans previously charged-off 277 945 1,022 2,244 — 2,244 Loans charged-off (2,445 ) (2,318 ) (2,215 ) (6,978 ) — (6,978 ) Balance at end of period $ 30,676 26,842 4,547 62,065 1,265 63,330 The following table presents loans individually evaluated for impairment by class and loan category, excluding PCI loans (in thousands): September 30, 2015 December 31, 2014 Unpaid Principal Balance Recorded Investment Related Allowance Average Recorded Investment Interest Income Recognized Unpaid Principal Balance Recorded Investment Related Allowance Average Recorded Investment Interest Income Recognized Loans with no related allowance Mortgage loans: Residential $ 12,066 8,782 — 9,018 353 14,942 10,629 — 11,138 357 Commercial 22,517 22,062 — 22,681 670 4,971 4,708 — 4,713 — Multi-family — — — — — — — — — — Construction 2,096 2,096 — 798 15 — — — — — Total 36,679 32,940 — 32,497 1,038 19,913 15,337 — 15,851 357 Commercial loans 16,672 14,666 — 14,955 221 2,718 2,179 — 1,823 4 Consumer loans 1,357 885 — 914 37 1,250 830 — 870 28 Total impaired loans $ 54,708 48,491 — 48,366 1,296 23,881 18,346 — 18,544 389 Loans with an allowance recorded Mortgage loans: Residential $ 15,260 14,614 1,959 14,489 375 15,523 14,906 2,367 15,106 555 Commercial 1,255 1,255 225 1,399 49 37,555 36,306 2,329 36,674 914 Multi-family — — — — — — — — — — Construction — — — — — — — — — — Total 16,515 15,869 2,184 15,888 424 53,078 51,212 4,696 51,780 1,469 Commercial loans 3,035 2,012 91 5,354 141 15,990 14,283 2,318 15,967 390 Consumer loans 1,527 1,517 106 1,535 56 1,565 1,554 113 1,578 80 Total impaired loans $ 21,077 19,398 2,381 22,777 621 70,633 67,049 7,127 69,325 1,939 Total impaired loans Mortgage loans: Residential $ 27,326 23,396 1,959 23,507 728 30,465 25,535 2,367 26,244 912 Commercial 23,772 23,317 225 24,080 719 42,526 41,014 2,329 41,387 914 Multi-family — — — — — — — — — — Construction 2,096 2,096 — 798 15 — — — — — Total 53,194 48,809 2,184 48,385 1,462 72,991 66,549 4,696 67,631 1,826 Commercial loans 19,707 16,678 91 20,309 362 18,708 16,462 2,318 17,790 394 Consumer loans 2,884 2,402 106 2,449 93 2,815 2,384 113 2,448 108 Total impaired loans $ 75,785 67,889 2,381 71,143 1,917 94,514 85,395 7,127 87,869 2,328 Specific allocations of the allowance for loan losses attributable to impaired loans totaled $2,381,000 and $7,127,000 at September 30, 2015 and December 31, 2014 , respectively. At September 30, 2015 and December 31, 2014 , impaired loans for which there was no related allowance for loan losses totaled $48,491,000 and $18,346,000 , respectively. The average balance of impaired loans during the nine months ended September 30, 2015 was $71,143,000 . The Company utilizes an internal nine-point risk rating system to summarize its loan portfolio into categories with similar characteristics. Loans deemed to be “acceptable quality” (pass) are rated 1 through 4, with a rating of 1 established for loans with minimal risk. Loans that are deemed to be of “questionable quality” are rated 5 (watch) or 6 (special mention). Loans with adverse classifications (substandard, doubtful or loss) are rated 7, 8 or 9, respectively. Commercial mortgage, commercial, multi-family and construction loans are rated individually, and each lending officer is responsible for risk rating loans in their portfolio. These risk ratings are then reviewed by the department manager and/or the Chief Lending Officer and by the Credit Department. The risk ratings are also confirmed through periodic loan review examinations which are currently performed by an independent third party, and their reports are presented directly to both the Audit and Risk Committees of the Board of Directors. Loans receivable by credit quality risk rating indicator, excluding PCI loans, are as follows (in thousands): At September 30, 2015 Residential Commercial mortgage Multi- family Construction Total mortgages Commercial Consumer Total loans Special mention $ 7,330 30,815 1,094 — 39,239 75,052 1,080 115,371 Substandard 11,876 39,882 1,355 2,096 55,209 35,402 4,130 94,741 Doubtful — — — — — 27 — 27 Loss — — — — — — — — Total classified and criticized 19,206 70,697 2,449 2,096 94,448 110,481 5,210 210,139 Pass/Watch 1,237,687 1,705,302 1,190,755 300,206 4,433,950 1,213,763 570,504 6,218,217 Total $ 1,256,893 1,775,999 1,193,204 302,302 4,528,398 1,324,244 575,714 6,428,356 At December 31, 2014 Residential Commercial mortgage Multi- family Construction Total mortgages Commercial Consumer Total loans Special mention $ 4,331 18,414 851 — 23,596 45,599 2,509 71,704 Substandard 17,222 53,454 322 2,600 73,598 32,828 3,938 110,364 Doubtful — 1,063 — — 1,063 29 — 1,092 Loss — — — — — — — — Total classified and criticized 21,553 72,931 1,173 2,600 98,257 78,456 6,447 183,160 Pass/Watch 1,229,892 1,621,428 1,040,409 218,502 4,110,231 1,183,966 605,020 5,899,217 Total $ 1,251,445 1,694,359 1,041,582 221,102 4,208,488 1,262,422 611,467 6,082,377" id="sjs-B4">Loans Receivable and Allowance for Loan Losses Loans receivable at September 30, 2015 and December 31, 2014 are summarized as follows (in thousands): September 30, 2015 December 31, 2014 Mortgage loans: Residential $ 1,256,893 1,251,445 Commercial 1,775,999 1,694,359 Multi-family 1,193,204 1,041,582 Construction 302,302 221,102 Total mortgage loans 4,528,398 4,208,488 Commercial loans 1,324,244 1,262,422 Consumer loans 575,714 611,467 Total gross loans 6,428,356 6,082,377 Purchased credit-impaired ("PCI") loans 3,671 4,510 Premiums on purchased loans 5,711 5,307 Unearned discounts (44 ) (53 ) Net deferred fees (6,750 ) (6,636 ) Total loans $ 6,430,944 6,085,505 The following tables summarize the aging of loans receivable by portfolio segment and class of loans, excluding PCI loans (in thousands): September 30, 2015 30-59 Days 60-89 Days Non-accrual Total Past Due and Non-accrual Current Total Loans Receivable Recorded Investment > 90 days accruing Mortgage loans: Residential $ 5,755 7,330 11,876 24,961 1,231,932 1,256,893 — Commercial 1,853 275 2,736 4,864 1,771,135 1,775,999 — Multi-family 775 — 847 1,622 1,191,582 1,193,204 — Construction — — 2,096 2,096 300,206 302,302 — Total mortgage loans 8,383 7,605 17,555 33,543 4,494,855 4,528,398 — Commercial loans 440 1,010 17,892 19,342 1,304,902 1,324,244 — Consumer loans 2,224 1,080 4,187 7,491 568,223 575,714 — Total gross loans $ 11,047 9,695 39,634 60,376 6,367,980 6,428,356 — December 31, 2014 30-59 Days 60-89 Days Non-accrual Total Past Due and Non-accrual Current Total Loans Receivable Recorded Investment > 90 days accruing Mortgage loans: Residential $ 10,121 4,331 17,222 31,674 1,219,771 1,251,445 — Commercial 146 30 20,026 20,202 1,674,157 1,694,359 — Multi-family — — 321 321 1,041,261 1,041,582 — Construction — — — — 221,102 221,102 — Total mortgage loans 10,267 4,361 37,569 52,197 4,156,291 4,208,488 — Commercial loans 1,000 371 12,342 13,713 1,248,709 1,262,422 — Consumer loans 2,398 2,509 3,944 8,851 602,616 611,467 — Total gross loans $ 13,665 7,241 53,855 74,761 6,007,616 6,082,377 — Included in loans receivable are loans for which the accrual of interest income has been discontinued due to deterioration in the financial condition of the borrowers. The principal amounts of these non-accrual loans were $39.6 million and $53.9 million at September 30, 2015 and December 31, 2014 , respectively. Included in non-accrual loans were $15.9 million and $8.4 million of loans which were less than 90 days past due at September 30, 2015 and December 31, 2014 , respectively. There were no loans 90 days or greater past due and still accruing interest at September 30, 2015 , or December 31, 2014 . The Company defines an impaired loan as a non-homogeneous loan greater than $1.0 million for which it is probable, based on current information, all amounts due under the contractual terms of the loan agreement will not be collected. Impaired loans also include all loans modified as troubled debt restructurings (“TDRs”). A loan is deemed to be a TDR when a loan modification resulting in a concession is made in an effort to mitigate potential loss arising from a borrower’s financial difficulty. Smaller balance homogeneous loans, including residential mortgages and other consumer loans, are evaluated collectively for impairment and are excluded from the definition of impaired loans, unless modified as TDRs. The Company separately calculates the reserve for loan losses on impaired loans. The Company may recognize impairment of a loan based upon: (1) the present value of expected cash flows discounted at the effective interest rate; (2) if a loan is collateral dependent, the fair value of collateral; or (3) the fair value of the loan. Additionally, if impaired loans have risk characteristics in common, those loans may be aggregated and historical statistics may be used as a means of measuring those impaired loans. The Company uses third-party appraisals to determine the fair value of the underlying collateral in its analyses of collateral dependent impaired loans. A third-party appraisal is generally ordered as soon as a loan is designated as a collateral dependent impaired loan and is updated annually or more frequently, if required. A specific allocation of the allowance for loan losses is established for each collateral dependent impaired loan with a carrying balance greater than the collateral’s fair value, less estimated costs to sell. Charge-offs are generally taken for the amount of the specific allocation when operations associated with the respective property cease and it is determined that collection of amounts due will be derived primarily from the disposition of the collateral. At each quarter end, if a loan is designated as a collateral dependent impaired loan and the third party appraisal has not yet been received, an evaluation of all available collateral is made using the best information available at the time, including rent rolls, borrower financial statements and tax returns, prior appraisals, management’s knowledge of the market and collateral, and internally prepared collateral valuations based upon market assumptions regarding vacancy and capitalization rates, each as and where applicable. Once the appraisal is received and reviewed, the specific reserves are adjusted to reflect the appraised value. The Company believes there have been no significant time lapses as a result of this process. At September 30, 2015 , there were 148 impaired loans totaling $67.9 million . Included in this total were 123 TDRs related to 121 borrowers totaling $47.9 million that were performing in accordance with their restructured terms and which continued to accrue interest at September 30, 2015 . At December 31, 2014 , there were 147 impaired loans totaling $85.4 million . Included in this total were 123 TDRs to 120 borrowers totaling $54.8 million that were performing in accordance with their restructured terms and which continued to accrue interest at December 31, 2014 .

These modifications generally do not result in the forgiveness of principal or accrued interest. In addition, the Company attempts to obtain additional collateral or guarantor support when modifying such loans. If the borrower has demonstrated performance under the previous terms and our underwriting process shows the borrower has the capacity to continue to perform under the restructured terms, the loan will continue to accrue interest. Non-accruing restructured loans may be returned to accrual status when there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. The following tables present the number of loans modified as TDRs during the three and nine months ended September 30, 2015 and 2014 and their balances immediately prior to the modification date and post-modification as of September 30, 2015 and 2014 : For the three months ended September 30, 2015 September 30, 2014 Troubled Debt Restructuring Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment ($ in thousands) Mortgage loans: Residential 1 $ 258 $ 256 4 $ 742 $ 774 Total mortgage loans 1 258 256 4 742 774 Commercial loans — — — 1 — 367 Consumer loans — — — 2 393 165 Total restructured loans 1 $ 258 $ 256 7 $ 1,135 $ 1,306 For the nine months ended September 30, 2015 September 30, 2014 Troubled Debt Restructuring Number of Pre-Modification Post-Modification Number of Pre-Modification Post-Modification ($ in thousands) Mortgage loans: Residential 6 $ 2,192 2,184 12 $ 2,705 $ 2,443 Commercial — — — 1 865 866 Construction 1 2,600 2,096 Total mortgage loans 7 4,792 4,280 13 3,570 3,309 Commercial loans 4 6,659 6,903 2 300 665 Consumer loans 2 123 115 2 393 165 Total restructured loans 13 $ 11,574 $ 11,298 17 $ 4,263 $ 4,139 All TDRs are impaired loans, which are individually evaluated for impairment, as previously discussed. Estimated collateral values of collateral dependent impaired loans modified during the three and nine months ended September 30, 2015 and 2014 exceeded the carrying amounts of such loans. There were charge-offs recorded on two collateral dependent impaired loans of $312,000 for the three and nine months ended September 30, 2015 , which are included in the preceding tables. There were no charge-offs recorded on collateral dependent impaired loans for 2014 . The allowance for loan losses associated with the TDRs presented in the preceding tables totaled $0 and $117,000 for the three months ended September 30, 2015 and 2014 , respectively, and were included in the allowance for loan losses for loans individually evaluated for impairment. For the nine months ended September 30, 2015 and 2014 , the allowance for loan losses associated with the TDRs presented in the preceding tables totaled $82,000 and $426,000 , respectively, and were included in the allowance for loan losses for loans individually evaluated for impairment. For the three and nine months ended September 30, 2015 , the TDRs presented in the preceding tables had a weighted average modified interest rate of approximately 3.00% and 5.26% , respectively, compared to a rate of 3.00% and 5.71% prior to modification, respectively. For the three and nine months ended September 30, 2014 , the TDRs had weighted average modified interest rate of approximately 5.50% and 4.90% , respectively, compared to a rate of 6.50% and 5.70% prior to modification, respectively. There were no payment defaults (90 days or more past due) at the quarter ended September 30, 2015 and 2014 related to loans modified as TDRs within the previous 12 months from September 30, 2015 and 2014. TDRs that subsequently default are considered collateral dependent impaired loans and are evaluated for impairment based on the estimated fair value of the underlying collateral less expected selling costs. PCI loans are loans acquired at a discount primarily due to deteriorated credit quality. As part of the Team Capital acquisition, $5.2 million of the loans purchased at May 30, 2014 were determined to be PCI loans. At the date of acquistion, PCI loans were accounted for at fair value, based upon the present value of expected future cash flows, with no related allowance for loan losses. The following table presents information regarding the estimates of the contractually required payments, the cash flows expected to be collected and the estimated fair value of the PCI loans acquired from Team Capital at May 30, 2014 (in thousands): May 30, 2014 Contractually required principal and interest $ 12,505 Contractual cash flows not expected to be collected (non-accretable discount) (6,475 ) Expected cash flows to be collected at acquisition 6,030 Interest component of expected cash flows (accretable yield) (810 ) Fair value of acquired loans $ 5,220 PCI loans declined $839,000 to $3.7 million at September 30, 2015 , from $4.5 million at December 31, 2014, largely due to the full repayment and greater than projected cash flows on certain PCI loans. This resulted in a $129,000 and a $349,000 increase in interest income for the three and nine months ended September 30, 2015 , due to the acceleration of accretable and non-accretable discount on these loans. The following table summarizes the changes in the accretable yield for PCI loans during the three and nine months ended September 30, 2015 (in thousands): Three months ended Sept 30, Nine months ended Sept 30, 2015 2014 2015 2014 Beginning balance $ 609 $ 773 $ 695 $ — Acquisition — — — 810 Accretion (220 ) (314 ) (683 ) (351 ) Reclassification from non-accretable discount 172 136 549 136 Ending balance $ 561 $ 595 $ 561 $ 595 The activity in the allowance for loan losses by portfolio segment for the three and nine months ended September 30, 2015 and 2014 was as follows (in thousands): Three months ended September 30, Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Unallocated Total 2015 Balance at beginning of period $ 31,824 22,840 4,570 59,234 390 59,624 Provision charged to operations 569 1,604 (411 ) 1,762 (362 ) 1,400 Recoveries of loans previously charged-off 3 762 352 1,117 — 1,117 Loans charged-off (774 ) (130 ) (772 ) (1,676 ) (1 ) (1,677 ) Balance at end of period $ 31,622 25,076 3,739 60,437 27 60,464 2014 Balance at beginning of period $ 31,040 27,079 4,381 62,500 1,375 63,875 Provision charged to operations 54 1,114 442 1,610 (110 ) 1,500 Recoveries of loans previously charged-off 120 404 172 696 — 696 Loans charged-off (538 ) (1,755 ) (448 ) (2,741 ) — (2,741 ) Balance at end of period $ 30,676 26,842 4,547 62,065 1,265 63,330 Nine months ended September 30, Mortgage Commercial Consumer Total Portfolio Unallocated Total 2015 Balance at beginning of period $ 31,977 24,381 4,881 61,239 495 61,734 Provision charged to operations 1,924 926 718 3,568 (468 ) 3,100 Recoveries of loans previously charged-off 139 1,636 819 2,594 — 2,594 Loans charged-off (2,418 ) (1,867 ) (2,679 ) (6,964 ) — (6,964 ) Balance at end of period $ 31,622 25,076 3,739 60,437 27 60,464 2014 Balance at beginning of period $ 34,144 24,107 4,929 63,180 1,484 64,664 Provision charged to operations (1,300 ) 4,108 811 3,619 (219 ) 3,400 Recoveries of loans previously charged-off 277 945 1,022 2,244 — 2,244 Loans charged-off (2,445 ) (2,318 ) (2,215 ) (6,978 ) — (6,978 ) Balance at end of period $ 30,676 26,842 4,547 62,065 1,265 63,330 The following table presents loans individually evaluated for impairment by class and loan category, excluding PCI loans (in thousands): September 30, 2015 December 31, 2014 Unpaid Principal Balance Recorded Investment Related Allowance Average Recorded Investment Interest Income Recognized Unpaid Principal Balance Recorded Investment Related Allowance Average Recorded Investment Interest Income Recognized Loans with no related allowance Mortgage loans: Residential $ 12,066 8,782 — 9,018 353 14,942 10,629 — 11,138 357 Commercial 22,517 22,062 — 22,681 670 4,971 4,708 — 4,713 — Multi-family — — — — — — — — — — Construction 2,096 2,096 — 798 15 — — — — — Total 36,679 32,940 — 32,497 1,038 19,913 15,337 — 15,851 357 Commercial loans 16,672 14,666 — 14,955 221 2,718 2,179 — 1,823 4 Consumer loans 1,357 885 — 914 37 1,250 830 — 870 28 Total impaired loans $ 54,708 48,491 — 48,366 1,296 23,881 18,346 — 18,544 389 Loans with an allowance recorded Mortgage loans: Residential $ 15,260 14,614 1,959 14,489 375 15,523 14,906 2,367 15,106 555 Commercial 1,255 1,255 225 1,399 49 37,555 36,306 2,329 36,674 914 Multi-family — — — — — — — — — — Construction — — — — — — — — — — Total 16,515 15,869 2,184 15,888 424 53,078 51,212 4,696 51,780 1,469 Commercial loans 3,035 2,012 91 5,354 141 15,990 14,283 2,318 15,967 390 Consumer loans 1,527 1,517 106 1,535 56 1,565 1,554 113 1,578 80 Total impaired loans $ 21,077 19,398 2,381 22,777 621 70,633 67,049 7,127 69,325 1,939 Total impaired loans Mortgage loans: Residential $ 27,326 23,396 1,959 23,507 728 30,465 25,535 2,367 26,244 912 Commercial 23,772 23,317 225 24,080 719 42,526 41,014 2,329 41,387 914 Multi-family — — — — — — — — — — Construction 2,096 2,096 — 798 15 — — — — — Total 53,194 48,809 2,184 48,385 1,462 72,991 66,549 4,696 67,631 1,826 Commercial loans 19,707 16,678 91 20,309 362 18,708 16,462 2,318 17,790 394 Consumer loans 2,884 2,402 106 2,449 93 2,815 2,384 113 2,448 108 Total impaired loans $ 75,785 67,889 2,381 71,143 1,917 94,514 85,395 7,127 87,869 2,328 Specific allocations of the allowance for loan losses attributable to impaired loans totaled $2,381,000 and $7,127,000 at September 30, 2015 and December 31, 2014 , respectively. At September 30, 2015 and December 31, 2014 , impaired loans for which there was no related allowance for loan losses totaled $48,491,000 and $18,346,000 , respectively. The average balance of impaired loans during the nine months ended September 30, 2015 was $71,143,000 . The Company utilizes an internal nine-point risk rating system to summarize its loan portfolio into categories with similar characteristics. Loans deemed to be “acceptable quality” (pass) are rated 1 through 4, with a rating of 1 established for loans with minimal risk. Loans that are deemed to be of “questionable quality” are rated 5 (watch) or 6 (special mention). Loans with adverse classifications (substandard, doubtful or loss) are rated 7, 8 or 9, respectively. Commercial mortgage, commercial, multi-family and construction loans are rated individually, and each lending officer is responsible for risk rating loans in their portfolio. These risk ratings are then reviewed by the department manager and/or the Chief Lending Officer and by the Credit Department. The risk ratings are also confirmed through periodic loan review examinations which are currently performed by an independent third party, and their reports are presented directly to both the Audit and Risk Committees of the Board of Directors. Loans receivable by credit quality risk rating indicator, excluding PCI loans, are as follows (in thousands): At September 30, 2015 Residential Commercial mortgage Multi- family Construction Total mortgages Commercial Consumer Total loans Special mention $ 7,330 30,815 1,094 — 39,239 75,052 1,080 115,371 Substandard 11,876 39,882 1,355 2,096 55,209 35,402 4,130 94,741 Doubtful — — — — — 27 — 27 Loss — — — — — — — — Total classified and criticized 19,206 70,697 2,449 2,096 94,448 110,481 5,210 210,139 Pass/Watch 1,237,687 1,705,302 1,190,755 300,206 4,433,950 1,213,763 570,504 6,218,217 Total $ 1,256,893 1,775,999 1,193,204 302,302 4,528,398 1,324,244 575,714 6,428,356 At December 31, 2014 Residential Commercial mortgage Multi- family Construction Total mortgages Commercial Consumer Total loans Special mention $ 4,331 18,414 851 — 23,596 45,599 2,509 71,704 Substandard 17,222 53,454 322 2,600 73,598 32,828 3,938 110,364 Doubtful — 1,063 — — 1,063 29 — 1,092 Loss — — — — — — — — Total classified and criticized 21,553 72,931 1,173 2,600 98,257 78,456 6,447 183,160 Pass/Watch 1,229,892 1,621,428 1,040,409 218,502 4,110,231 1,183,966 605,020 5,899,217 Total $ 1,251,445 1,694,359 1,041,582 221,102 4,208,488 1,262,422 611,467 6,082,377

Compensation and Retirement Disclosure [Abstract]
Components of Net Periodic Benefit Cost	Components of Net Periodic Benefit Cost The Bank has a noncontributory defined benefit pension plan (the “Plan”) covering its full-time employees who had attained age 21 with at least one year of service as of April 1, 2003, the date on which the Plan was frozen. All participants in the Plan are 100% vested. The Plan’s assets are invested in investment funds and group annuity contracts currently managed by the Principal Financial Group and Allmerica Financial. In an effort to lower and reduce the volatility of its future pension costs, the Company offered a lump sum pension distribution option to its vested terminated employees in the quarter ended June 30, 2014. In the quarter ended June 30, 2014, the Plan paid $4.3 million to those employees that elected to receive lump sum pension distributions and the Company realized an associated charge of $1.3 million . This charge was a pro rata share of the unrecognized losses recorded in other comprehensive income. In addition to pension benefits, certain health care and life insurance benefits are currently made available to certain of the Bank’s retired employees. The costs of such benefits are accrued based on actuarial assumptions from the date of hire to the date the employee became or will become fully eligible to receive the benefits. Effective January 1, 2003, eligibility for retiree health care benefits was frozen as to new entrants, and benefits were eliminated for employees with less than 10 years of service as of December 31, 2002. Effective January 1, 2007, eligibility for retiree life insurance benefits was frozen as to new entrants, and retiree life insurance benefits were eliminated for employees with less than 10 years of service as of December 31, 2006. Net periodic benefit (increase) cost for pension benefits and other post-retirement benefits for the three and nine months ended September 30, 2015 and 2014 includes the following components (in thousands): Three months ended September 30, Nine months ended September 30, Pension benefits Other post- retirement benefits Pension benefits Other post- retirement benefits 2015 2014 2015 2014 2015 2014 2015 2014 Service cost $ — — 42 42 $ — — 126 126 Interest cost 284 284 280 272 852 988 842 816 Expected return on plan assets (632 ) (837 ) — — (1,898 ) (2,625 ) — — Amortization of prior service cost — — — (1 ) — — — (3 ) Amortization of the net loss 193 127 — (51 ) 581 313 — (153 ) Net periodic benefit (increase) cost $ (155 ) (426 ) 322 262 $ (465 ) (1,324 ) 968 786 In its consolidated financial statements for the year ended December 31, 2014 , the Company previously disclosed that it does not expect to contribute to the Plan in 2015 . As of September 30, 2015 , no contributions have been made to the Plan. The net periodic benefit (increase) cost for pension benefits and other post-retirement benefits for the three and nine months ended September 30, 2015 were calculated using the actual January 1, 2015 pension valuation and the other post-retirement benefits valuations.

Accounting Changes and Error Corrections [Abstract]
Impact of Recent Accounting Pronouncements	Impact of Recent Accounting Pronouncements In September 2015, , the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-16, "Business Combinations, Simplifying the Accounting for Measurement - Period Adjustments." The amendments in this update apply to all entities that have reported provisional amounts for items in a business combination for which the accounting is incomplete by the end of the reporting period in which the combination occurs and during the measurement period have an adjustment to provisional amounts recognized. In these cases, the acquirer must record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in this update are effective for fiscal years beginning after December 15, 2015 including interim periods within those fiscal years. The Company’s adoption of this ASU is not expected to have a material impact on its consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-14, “Receivables - Troubled Debt Restructurings by Creditors: Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” The amendments in this update affect creditors that hold government guaranteed mortgage loans, including those guaranteed by the Federal Housing Administration and the U.S. Department of Veterans Affairs. The amendments in this update require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (i) the loan has a government guarantee that is not separable from the loan before foreclosure; (ii) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and (iii) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The Company's adoption of this ASU did not have a significant impact on its consolidated financial statements. In June 2014, the FASB issued ASU No. 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," which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. This update is effective for interim and annual periods beginning after December 15, 2015. The amendments can be applied prospectively to all awards granted or modified after the effective date or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented and to all new or modified awards thereafter. Early adoption is permitted. The Company does not expect that the adoption of this guidance will have a significant impact on the Company’s consolidated financial statements. Also in June 2014, the FASB issued ASU No. 2014-11, "Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures" which aligns the accounting for repurchase to maturity transactions and repurchase agreements executed as a repurchase financing with the accounting for other typical repurchase agreements. Going forward, these transactions would all be accounted for as secured borrowings. This update is effective for the first interim or annual period beginning after December 15, 2014. In addition the disclosure of certain transactions accounted for as a sale is effective for the first interim or annual period beginning on or after December 15, 2014, and the disclosure for transactions accounted for as secured borrowings is required for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Early adoption was prohibited. The Company's adoption of this ASU did not have an impact on its consolidated financial statements.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. Where quoted market values in an active market are not readily available, the Company utilizes various valuation techniques to estimate fair value. Fair value is an estimate of the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. However, in many instances fair value estimates may not be substantiated by comparison to independent markets and may not be realized in an immediate sale of the financial instrument. GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of fair value hierarchy are as follows: Level 1: Unadjusted quoted market prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability; and Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The valuation techniques are based upon the unpaid principal balance only, and exclude any accrued interest or dividends at the measurement date. Interest income and expense and dividend income are recorded within the consolidated statements of income depending on the nature of the instrument using the effective interest method based on acquired discount or premium. Assets and Liabilities Measured at Fair Value on a Recurring Basis The valuation techniques described below were used to measure fair value of financial instruments in the table below on a recurring basis as of September 30, 2015 and December 31, 2014 . Securities Available for Sale For securities available for sale, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to benchmark or comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As the Company is responsible for the determination of fair value, it performs quarterly analyses on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to test the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in adjustment in the prices obtained from the pricing service. The Company also may hold equity securities and debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. Derivatives The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives not designated in qualifying hedging relationships are not speculative and result from a service the Company provides to certain qualifying commercial borrowers in a loan related transaction and are not used to manage interest rate risk in the Company’s assets or liabilities. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of the swap transactions are recognized directly in earnings. The Company also uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges, and which satisfy hedge accounting requirements, involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. These derivatives were used to hedge the variable cash outflows associated with Federal Home Loan Bank borrowings. The effective portion of changes in the fair value of these derivatives are recorded in accumulated other comprehensive income, and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of these derivatives are recognized directly in earnings. The fair value of the Company's derivatives are determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs. Assets Measured at Fair Value on a Non-Recurring Basis The valuation techniques described below were used to estimate fair value of financial instruments measured on a non-recurring basis as of September 30, 2015 and December 31, 2014 . For loans measured for impairment based on the fair value of the underlying collateral, fair value was estimated using a market approach. The Company measures the fair value of collateral underlying impaired loans primarily through obtaining independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraisers’ market knowledge and experience, as well as adjustments for estimated costs to sell of up to 6% . The Company classifies these loans as Level 3 within the fair value hierarchy. Assets acquired through foreclosure or deed in lieu of foreclosure are carried at fair value, less estimated selling costs of up to 6% . Fair value is generally based on independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case basis, to comparable assets based on the appraisers’ market knowledge and experience, and are classified as Level 3. When an asset is acquired, the excess of the loan balance over fair value, less estimated selling costs, is charged to the allowance for loan losses. A reserve for foreclosed assets may be established to provide for possible write-downs and selling costs that occur subsequent to foreclosure. Foreclosed assets are carried net of the related reserve. Operating results from real estate owned, including rental income, operating expenses, and gains and losses realized from the sales of real estate owned, are recorded as incurred. There were no changes to the valuation techniques for fair value measurements as of September 30, 2015 and December 31, 2014 . The following tables present the assets and liabilities reported on the consolidated statements of financial condition at their fair values as of September 30, 2015 and December 31, 2014 , by level within the fair value hierarchy: Fair Value Measurements at Reporting Date Using: (In thousands) September 30, 2015 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Measured on a recurring basis: Securities available for sale: US Treasury obligations $ 8,069 8,069 — — Agency obligations 87,874 87,874 — — Mortgage-backed securities 886,809 — 886,809 — State and municipal obligations 6,005 — 6,005 — Corporate obligations 5,516 — 5,516 — Equity securities 498 498 — — Total securities available for sale 994,771 96,441 898,330 — Derivative assets 6,642 — 6,642 — $ 1,001,413 96,441 904,972 — Derivative liabilities $ 6,959 — 6,959 — Measured on a non-recurring basis: Loans measured for impairment based on the fair value of the underlying collateral $ 11,455 — — 11,455 Foreclosed assets 10,128 — — 10,128 $ 21,583 — — 21,583 Fair Value Measurements at Reporting Date Using: (In thousands) December 31, 2014 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Measured on a recurring basis: Securities available for sale: US Treasury obligations $ 8,016 8,016 — — Agency obligations 95,076 95,076 — — Mortgage-backed securities 957,257 — 957,257 — State and municipal obligations 7,002 — 7,002 — Equity securities 524 524 — — $ 1,074,395 103,616 970,779 — Derivative assets 2,046 — 2,046 — $ 1,076,441 103,616 972,825 — Derivative liabilities $ 2,052 — 2,052 — Measured on a non-recurring basis: Loans measured for impairment based on the fair value of the underlying collateral $ 23,086 — — 23,086 Foreclosed assets 5,098 — — 5,098 $ 28,184 — — 28,184 There were no transfers between Level 1 and Level 2 during the three and nine months ended September 30, 2015 . Other Fair Value Disclosures The Company is required to disclose the estimated fair value of financial instruments, both assets and liabilities on and off the balance sheet, for which it is practicable to estimate fair value. The following is a description of valuation methodologies used for those assets and liabilities. Cash and Cash Equivalents For cash and due from banks, federal funds sold and short-term investments, the carrying amount approximates fair value. Investment Securities Held to Maturity For investment securities held to maturity, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to benchmark or comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As the Company is responsible for the determination of fair value, it performs quarterly analyses on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to test the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in adjustment in the prices obtained from the pricing service . The Company also holds debt instruments issued by the U.S. government and U.S. government agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 within the fair value hierarchy. Federal Home Loan Bank of New York ("FHLBNY") Stock The carrying value of FHLBNY stock was its cost. The fair value of FHLBNY stock is based on redemption at par value. The Company classifies the estimated fair value as Level 1 within the fair value hierarchy. Loans Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial mortgage, residential mortgage, commercial, construction and consumer. Each loan category is further segmented into fixed and adjustable rate interest terms and into performing and non-performing categories. The fair value of performing loans was estimated using a combination of techniques, including a discounted cash flow model that utilizes a discount rate that reflects the Company’s current pricing for loans with similar characteristics and remaining maturity, adjusted by an amount for estimated credit losses inherent in the portfolio at the balance sheet date. The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, when applicable. The Company classifies the estimated fair value of its loan portfolio as Level 3. The fair value for significant non-performing loans was based on recent external appraisals of collateral securing such loans, adjusted for the timing of anticipated cash flows and estimated selling costs. The Company classifies the estimated fair value of its non-performing loan portfolio as Level 3. Deposits The fair value of deposits with no stated maturity, such as non-interest bearing demand deposits and savings deposits, was equal to the amount payable on demand and classified as Level 1. The estimated fair value of certificates of deposit was based on the discounted value of contractual cash flows. The discount rate was estimated using the Company’s current rates offered for deposits with similar remaining maturities. The Company classifies the estimated fair value of its certificates of deposit portfolio as Level 2. Borrowed Funds The fair value of borrowed funds was estimated by discounting future cash flows using rates available for debt with similar terms and maturities and is classified by the Company as Level 2 within the fair value hierarchy. Commitments to Extend Credit and Letters of Credit The fair value of commitments to extend credit and letters of credit was estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value estimates of commitments to extend credit and letters of credit are deemed immaterial. Limitations Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on- and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial assets or liabilities include goodwill and other intangibles, deferred tax assets and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates. The following tables present the Company’s financial instruments at their carrying and fair values as of September 30, 2015 and December 31, 2014 . Fair values are presented by level within the fair value hierarchy.

Derivatives and Hedging Activit

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities. Non-designated Hedges. Derivatives not designated in qualifying hedging relationships are not speculative and result from a service the Company provides to certain qualifying commercial borrowers in a loan related transaction and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The Company implemented this program during the quarter ended September 30, 2014. As of September 30, 2015, the Company had 17 interest rate swaps with an aggregate notional amount of $248.3 million related to this program. Cash flow Hedges of Interest Rate Risk. The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the three months ended September 30, 2015 , such derivatives were used to hedge the variable cash outflows associated with Federal Home Loan Bank borrowings. The ineffective portion of the change in fair value of the derivatives are recognized directly in earnings. The Company implemented this program during the quarter ended September 30, 2015. During the three and nine months ended September 30, 2015 , the Company’s did not record any hedge ineffectiveness. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s debt. During the next twelve months, the Company estimates that $431,000 will be reclassified as an increase to interest expense. As of September 30, 2015 , the Company had one outstanding interest rate derivative with a notional amount of $40 million that was designated as a cash flow hedge of interest rate risk. The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the Consolidated Statements of Financial Condition at September 30, 2015 and December 31, 2014 (in thousands): At September 30, 2015 Asset Derivatives Liability Derivatives Consolidated Statements of Financial Condition Fair Value Consolidated Statements of Financial Condition Fair Value Derivatives not designated as a hedging instruments: Interest rate products Other assets $ 6,634 Other liabilities $ 6,572 Credit contracts Other assets 8 — Total derivatives not designated as hedging instruments $ 6,642 $ 6,572 Derivatives designated as a a hedging instrument: Interest rate products Other assets $ — Other liabilities $ 387 Total derivatives designated as a hedging instrument $ — $ 387 At December 31, 2014 Asset Derivatives Liability Derivatives Consolidated Statements of Financial Condition Fair Value Consolidated Statements of Financial Condition Fair Value Derivatives not designated as a hedging instruments: Interest rate products Other assets $ 2,040 Other liabilities $ 2,052 Credit contracts Other assets 6 — Total derivatives not designated as hedging instruments $ 2,046 $ 2,052 The tables below present the effect of the Company’s derivative financial instruments on the Consolidated Statements of Income during the three and nine months ended September 30, 2015 (in thousands).

The Company also has agreements with certain of its derivative counterparties that contain a provision that if the Company fails to maintain its status as a well / adequate capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of September 30, 2015 , the termination value of derivatives in a net liability position, which includes accrued interest, was $7.1 million. The Company has minimum collateral posting thresholds with certain of its derivative counterparties, and has posted collateral of $6.7 million against its obligations under these agreements. If the Company had breached any of these provisions at September 30, 2015 , it could have been required to settle its obligations under the agreements at the termination value.
