Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements are comprised of the accounts of Northfield Bancorp, Inc. (the Company) and its wholly owned subsidiaries, Northfield Investments, Inc. and Northfield Bank (the Bank), and the Bank’s wholly-owned significant subsidiaries, NSB Services Corp. and NSB Realty Trust. All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting solely of normal and recurring adjustments) necessary for the fair presentation of the consolidated financial condition and the consolidated results of operations for the unaudited periods presented have been included. The results of operations and other data presented for the three and six months ended June 30, 2017 , are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2017 or for any other period. Whenever necessary, certain prior year amounts are reclassified to conform to the current year presentation. In preparing the unaudited consolidated financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP), management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated statements of financial condition and results of operations for the periods indicated. Material estimates that are particularly susceptible to change are: the allowance for loan losses, the evaluation of goodwill and other intangible assets, impairment on investment securities, fair value measurements of assets and liabilities, and income taxes. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual amounts or results could differ significantly from those estimates. Certain information and note disclosures usually included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for the preparation of interim financial statements. The consolidated financial statements presented should be read in conjunction with the audited consolidated financial statements and notes to consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2016 , of the Company as filed with the SEC.

Business Combinations [Abstract]
Business Combinations	Business Combinations On January 8, 2016, the Company completed its acquisition of Hopewell Valley Community Bank (“Hopewell Valley”), which after purchase accounting adjustments added $508.5 million to total assets, $342.6 million to loans, and $456.2 million to deposits, and nine branch offices in the Hunterdon and Mercer counties of New Jersey. Total consideration paid for Hopewell Valley was $55.4 million , consisting of $13.7 million in cash and 2,707,381 shares of common stock valued at $41.7 million based upon the $15.41 per share closing price of Northfield Bancorp, Inc.'s common stock on January 8, 2016. The 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 for Hopewell Valley (in thousands): ASSETS ACQUIRED: January 8, 2016 Cash and cash equivalents, net $ 55,479 Securities available for sale 61,633 Loans 342,566 Accrued interest receivable 1,452 Bank-owned life insurance 11,269 Premises and equipment 5,926 Federal Home Loan Bank of New York stock, at cost 476 Goodwill 22,252 Other intangible assets 2,013 Other assets 5,389 Total assets acquired $ 508,455 LIABILITIES ASSUMED: Deposits $ 456,203 Other borrowings 2,213 Other liabilities 8,318 Total liabilities assumed 466,734 Net assets acquired $ 41,721 The purchase accounting for the Hopewell Valley 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 Hopewell Valley acquisition were as follows: Cash and cash equivalents The estimated fair values of cash and cash equivalents approximate their stated face amounts, as these financial instruments are either due on demand or have short-term maturities. 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. Other intangible assets Other intangible assets consisting of 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 of alternative funding sources. The core deposit premium is being amortized over an estimated useful life of 10 years to approximate the existing deposit relationships acquired. Deposits The fair values of deposit liabilities with no stated maturity (i.e., non-interest bearing demand accounts, interest-bearing negotiable orders of withdrawal (NOW), savings and money market accounts) are equal to the carrying amounts payable on demand. The fair values of certificates of deposit represent contractual cash flows, discounted to present value using interest rates currently offered on deposits with similar characteristics and remaining maturities. Other borrowings Other borrowings consist of securities sold under agreements to repurchase. The carrying amounts approximate their fair values because they frequently re-price to a market rate.

There were 19 pass-through mortgage-backed securities issued or guaranteed by GSEs, 16 REMIC mortgage-backed securities issued or guaranteed by a GSE, and seven corporate bonds that were in an unrealized loss position of less than twelve months at June 30, 2017 . All securities referred to above were rated investment grade at June 30, 2017 . The declines in value relate to the general interest rate environment and are considered temporary. The securities cannot be prepaid in a manner that would result in the Company not receiving substantially all of its amortized cost. The Company neither has an intent to sell, nor is it more likely than not that the Company will be required to sell, the securities before the recovery of their amortized cost basis or, if necessary, maturity. The fair values of our investment securities could decline in the future if the underlying performance of the collateral for the collateralized mortgage obligations or other securities deteriorates and our credit enhancement levels do not provide sufficient protections to our contractual principal and interest, which may result in other-than-temporary impairment in the future.

There were no sales of held-to-maturity securities for the three and six months ended June 30, 2017 , or June 30, 2016 . The Company did no t recognize any other-than-temporary impairment charges in earnings on securities held-to-maturity during the three and six months ended June 30, 2017 , or June 30, 2016 . Gross unrealized losses on mortgage-backed securities held-to-maturity, and the estimated fair value of the related securities, aggregated by security category and length of time that individual securities have been in a continuous unrealized loss position, at June 30, 2017 and December 31, 2016 , were as follows (in thousands): June 30, 2017 December 31, 2016 Less than 12 months Less than 12 months Unrealized Losses Estimated Fair Value Unrealized Losses Estimated Fair Value Mortgage-backed securities: Pass-through certificates: GSEs $ 45 $ 7,343 $ 59 $ 7,466 Total securities held-to-maturity $ 45 $ 7,343 $ 59 $ 7,466 The Company held four pass-through mortgage-backed securities held-to-maturity, issued or guaranteed by GSE's that were in a continuous unrealized loss position of less than twelve months at June 30, 2017 . Management evaluated these securities and concluded that the declines in value relate to the general interest rate environment and are considered temporary. The securities cannot be prepaid in a manner that would result in the Company not receiving substantially all of its amortized cost. The Company neither has an intent to sell, nor is it more likely than not that the Company will be required to sell, the securities before the recovery of their amortized cost basis or, if necessary, maturity. The fair values of our investment securities could decline in the future if the underlying performance of the collateral for the collateralized mortgage obligations or other securities deteriorates and our credit enhancement levels do not provide sufficient protections to our contractual principal and interest. As a result, there is a risk that significant other-than-temporary impairments may occur in the future given the current economic environment.

a regular basis. Credit quality is monitored by reviewing certain credit quality indicators. Management has determined that loan-to-value ratios (at period end) and internally assigned credit risk ratings by loan type are the key credit quality indicators that best measure the credit quality of the Company’s loan receivables. Loan-to-value (LTV) ratios used by management in monitoring credit quality are based on current period loan balances and original appraised values at time of origination (unless a current appraisal has been obtained as a result of the loan being deemed impaired). In calculating the provision for loan losses, based on past loan loss experience, management has determined that commercial real estate loans and multifamily loans having loan-to-value ratios, as described above, of less than 35% , and one-to-four family loans having loan-to-value ratios, as described above, of less than 60% , require less of a loss factor than those with higher loan to value ratios. The Company maintains a credit risk rating system as part of the risk assessment of its loan portfolio. The Company’s lending officers are required to assign a credit risk rating to each loan in their portfolio at origination. This risk rating is reviewed periodically and adjusted if necessary. Monthly, management presents monitored assets to the loan committee. In addition, the Company engages a third-party independent loan reviewer that performs semi-annual reviews of a sample of loans, validating the credit risk ratings assigned to such loans. The credit risk ratings play an important role in the establishment of the loan loss provision and the allowance for loan losses for originated loans held-for-investment. After determining the general reserve loss factor for each originated portfolio segment held-for-investment, the originated portfolio segment held-for-investment balance collectively evaluated for impairment is multiplied by the general reserve loss factor for the respective portfolio segment in order to determine the general reserve. When assigning a risk rating to a loan, management utilizes the Bank’s internal nine-point credit risk rating system. 1. Strong 2. Good 3. Acceptable 4. Adequate 5. Watch 6. Special Mention 7. Substandard 8. Doubtful 9. Loss Loans rated 1 to 5 are considered pass ratings. An asset is classified substandard if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard assets have well defined weaknesses based on objective evidence, and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Assets classified as doubtful have all of the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses present make collection or liquidation in full highly questionable and improbable based on current circumstances. Assets classified as loss are those considered uncollectible and of such little value that their continuance as assets is not warranted. Assets which do not currently expose the Company to sufficient risk to warrant classification in one of the aforementioned categories, but possess weaknesses, are required to be designated special mention. The following tables detail the recorded investment of originated loans held-for-investment, net of deferred fees and costs, by loan type and credit quality indicator at June 30, 2017 , and December 31, 2016 (in thousands): June 30, 2017 Real Estate Multifamily Commercial One-to-Four Family Construction and Land Home Equity and Lines of Credit Commercial and Industrial Other Total < 35% LTV => 35% LTV < 35% LTV => 35% LTV < 60% LTV => 60% LTV Internal Risk Rating Pass $ 134,577 $ 1,523,114 $ 60,771 $ 339,713 $ 59,336 $ 40,317 $ 17,622 $ 67,928 $ 30,792 $ 1,508 $ 2,275,678 Special Mention 12 4,085 — 1,847 693 — — 29 637 — 7,303 Substandard 38 84 — 14,523 1,834 746 — 237 189 — 17,651 Originated loans held-for-investment, net $ 134,627 $ 1,527,283 $ 60,771 $ 356,083 $ 61,863 $ 41,063 $ 17,622 $ 68,194 $ 31,618 $ 1,508 $ 2,300,632 December 31, 2016 Real Estate Multifamily Commercial One-to-Four Family Construction and Land Home Equity and Lines of Credit Commercial and Industrial Other Total < 35% LTV => 35% LTV < 35% LTV => 35% LTV < 60% LTV => 60% LTV Internal Risk Rating Pass $ 122,525 $ 1,381,231 $ 65,612 $ 323,842 $ 59,214 $ 43,316 $ 14,092 $ 66,489 $ 31,173 $ 1,498 $ 2,108,992 Special Mention 25 4,636 — 3,852 705 — — 29 696 — 9,943 Substandard 40 1,643 1,179 18,867 1,807 1,482 — 249 144 — 25,411 Originated loans held-for-investment, net $ 122,590 $ 1,387,510 $ 66,791 $ 346,561 $ 61,726 $ 44,798 $ 14,092 $ 66,767 $ 32,013 $ 1,498 $ 2,144,346 Included in loans receivable (including loans held-for-sale) are loans for which the accrual of interest income has been discontinued due to deterioration in the financial condition of the borrowers. The recorded investment of these non-accrual loans was $6.0 million and $7.3 million at June 30, 2017 , and December 31, 2016 , respectively. Generally, loans are placed on non-accrual status when they become 90 days or more delinquent, or sooner if considered appropriate by management, and remain on non-accrual status until they are brought current, have six consecutive months of performance under the loan terms, and factors indicating reasonable doubt about the timely collection of payments no longer exist. Therefore, loans may be current in accordance with their loan terms, or may be less than 90 days delinquent and still be on a non-accruing status. These non-accrual amounts included loans deemed to be impaired of $3.1 million and $5.7 million at June 30, 2017 , and December 31, 2016 , respectively. Loans on non-accrual status with principal balances less than $500,000 , and therefore not meeting the Company’s definition of an impaired loan, amounted to $2.4 million and $1.7 million at June 30, 2017 , and December 31, 2016 , respectively. Non-accrual amounts included in loans held-for-sale were $494,000 at June 30, 2017 . There were no loans held-for-sale at December 31, 2016 . Loans past due 90 days or more and still accruing interest were $291,000 and $60,000 at June 30, 2017 , and December 31, 2016 , respectively, and consisted of loans that are considered well secured and in the process of collection.

There was one one-to-four family residential loan modified as a TDR during the six months ended June 30, 2017. This loan had a pre- and post-modification balance of $256,000 as of the date of modification, and was restructured to receive a reduced interest rate. There were no loans modified as TDRs during the three or six months ended June 30, 2016. At June 30, 2017 , and December 31, 2016 , we had TDRs of $22.2 million and $22.4 million , respectively. Management classifies all TDRs as impaired loans. Impaired loans are individually assessed to determine that the loan’s carrying value is not in excess of the estimated fair value of the collateral less cost to sell, if the loan is collateral dependent, or the present value of the expected future cash flows, if the loan is not collateral dependent. Management performs a detailed evaluation of each impaired loan and generally obtains updated appraisals as part of the evaluation. In addition, management adjusts estimated fair values down to appropriately consider recent market conditions, our willingness to accept a lower sales price to effect a quick sale, and costs to dispose of any supporting collateral. Determining the estimated fair value of underlying collateral (and related costs to sell) can be difficult in illiquid real estate markets and is subject to significant assumptions and estimates. Management employs an independent third-party expert in appraisal preparation and review to ascertain the reasonableness of updated appraisals. Projecting the expected cash flows under troubled debt restructurings which are not collateral dependent is inherently subjective and requires, among other things, an evaluation of the borrower’s current and projected financial condition. Actual results may be significantly different than our projections and our established allowance for loan losses on these loans, which could have a material effect on our financial results. At June 30, 2017 , there was one TDR loan that was restructured during the preceding twelve months ended June 30, 2017, that subsequently defaulted. The loan was a one-to-four family residential loan, with a recorded investment of $254,000 , which was 90 days or more past due and on non-accrual status at June 30, 2017 . At June 30, 2016, there were three TDR loans that were restructured during the twelve months ended June 30, 2016, that subsequently defaulted. The loans consisted of one commercial real estate loan with a recorded investment of $1.8 million , which was less than 90 days

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The following tables present the assets reported on the consolidated balance sheet at their estimated fair value as of June 30, 2017 , and December 31, 2016 , by level within the fair value hierarchy as required by the Fair Value Measurements and Disclosures Topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC). Financial assets and liabilities are classified in their entirety based on the level of input that is significant to the fair value measurement. The fair value hierarchy is as follows: • Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. • Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlations or other means. • Level 3 Inputs – Significant unobservable inputs that reflect the Company’s own assumptions that market participants would use in pricing the assets or liabilities. Fair Value Measurements at June 30, 2017 Using: Carrying Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in thousands) Measured on a recurring basis: Assets: Investment securities: Available-for-sale: Mortgage-backed securities: GSE $ 407,769 $ — $ 407,769 $ — Non-GSE 142 — 142 — Other securities: Municipal bonds 759 — 759 — Corporate bonds 63,025 — 63,025 — Equities 314 314 — — Other 1,000 — 1,000 — Total available-for-sale 473,009 314 472,695 — Trading securities 8,808 8,808 — — Total $ 481,817 $ 9,122 $ 472,695 $ — Measured on a non-recurring basis: Assets: Impaired loans: Real estate loans: Commercial real estate $ 4,801 $ — $ — $ 4,801 One-to-four family residential mortgage 1,996 — — 1,996 Multifamily 1,270 — — 1,270 Home equity and lines of credit 276 — — 276 Total impaired real estate loans 8,343 — — 8,343 Commercial and industrial loans 21 — — 21 Other real estate owned 850 — — 850 Total $ 9,214 $ — $ — $ 9,214 Fair Value Measurements at December 31, 2016 Using: Carrying Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in thousands) Measured on a recurring basis: Assets: Investment securities: Available-for-sale: Mortgage-backed securities: GSE $ 448,842 $ — $ 448,842 $ — Non-GSE 270 — 270 — Other securities: Municipal bonds 2,158 — 2,158 — Corporate bonds 45,159 — 45,159 — Equities 1,218 271 947 — Other 1,250 — 1,250 — Total available-for-sale 498,897 271 498,626 — Trading securities 7,857 7,857 — — Total $ 506,754 $ 8,128 $ 498,626 $ — Measured on a non-recurring basis: Assets: Impaired loans: Real estate loans: Commercial real estate $ 10,730 $ — $ — $ 10,730 One-to-four family residential mortgage 2,177 — — 2,177 Multifamily 1,276 — — 1,276 Home equity and lines of credit 274 — — 274 Total impaired real estate loans 14,457 — — 14,457 Commercial and industrial loans 21 — — 21 Other real estate owned 850 — — 850 Total $ 15,328 $ — $ — $ 15,328 The following table presents qualitative information for Level 3 assets measured at fair value on a non-recurring basis at June 30, 2017 , and December 31, 2016 (dollars in thousands): Fair Value Valuation Methodology Unobservable Inputs Range of Inputs June 30, 2017 December 31, 2016 June 30, 2017 December 31, 2016 Impaired loans $ 8,364 $ 14,478 Appraisals Discount for costs to sell 7.0% 7.0% Discount for quick sale 10.0% 10.0% Discounted cash flows Interest rates 3.125% to 6.75% 4.75% to 7.5% Other real estate owned $ 850 $ 850 Appraisals Discount for costs to sell 7.0% 7.0% Available for Sale Securities: The estimated fair values for mortgage-backed securities, corporate and other debt securities, and certain less liquid equity securities are obtained from an independent nationally recognized third-party pricing service. The estimated fair values are derived primarily from cash flow models, which include assumptions for interest rates, credit losses, and prepayment speeds. Broker/dealer quotes are utilized as well, when such quotes are available and deemed representative of the market. The significant inputs utilized in the cash flow models are based on market data obtained from sources independent of the Company (Observable Inputs), and are therefore classified as Level 2 within the fair value hierarchy. The estimated fair values of equity securities consisting of publicly traded mutual funds are classified as Level 1 and are derived from quoted market prices in active markets. There were no transfers of securities between Level 1 and Level 2 during the six months ended June 30, 2017 . Trading Securities: Fair values are derived from quoted market prices in active markets. The assets consist of publicly traded mutual funds. Impaired Loans: At June 30, 2017 , and December 31, 2016 , the Company had impaired loans held-for-investment (excluding PCI loans) with outstanding principal balances of $10.9 million and $17.7 million , respectively, which were recorded at their estimated fair value of $8.4 million and $14.5 million , respectively. The Company recorded a net decrease in the specific reserve for impaired loans of $127,000 for the six months ended June 30, 2017 , and a net increase in the specific reserve for impaired loans of $117,000 for the six months ended June 30, 2016 , utilizing level 3 inputs. For purposes of estimating fair value of impaired loans, management utilizes independent appraisals, if the loan is collateral dependent, adjusted downward by management, as necessary, for changes in relevant valuation factors subsequent to the appraisal date, or the present value of expected future cash flows for non-collateral dependent loans and troubled debt restructurings. Other Real Estate Owned (OREO): At both June 30, 2017 and December 31, 2016, the Company had assets acquired through foreclosure, or deed in lieu of foreclosure, of $850,000 . These assets are recorded at estimated fair value, less estimated selling costs when acquired, establishing a new cost basis. Estimated fair value is generally based on independent appraisals. These appraisals include adjustments to comparable assets based on the appraisers’ market knowledge and experience, and are considered Level 3 inputs. 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. If the estimated fair value of the asset declines, a write-down is recorded through non-interest expense. The valuation of foreclosed assets is subjective in nature and may be adjusted in the future because of changes in economic conditions. In addition, the Company may be required, from time to time, to measure the fair value of certain other financial assets on a nonrecurring basis in accordance with U.S. GAAP. The adjustments to fair value usually result from the application of lower-of-cost-or-market accounting or write downs of individual assets. Fair Value of Financial Instruments The FASB ASC Topic for Financial Instruments requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or non-recurring basis are discussed above. The following methods and assumptions were used to estimate the fair value of other financial assets and financial liabilities not already discussed above: (a) Cash, Cash Equivalents, and Certificates of Deposit Cash and cash equivalents are short-term in nature with original maturities of six months or less; the carrying amount approximates fair value. Certificates of deposit having original terms of six-months or less; the carrying value generally approximates fair value. Certificates of deposit with an original maturity of six months or greater; the fair value is derived from discounted cash flows. (b) Securities (Held to Maturity) The estimated fair values for substantially all of our securities are obtained from an independent nationally recognized pricing service. The independent pricing service utilizes market prices of same or similar securities whenever such prices are available. Prices involving distressed sellers are not utilized in determining fair value. Where necessary, the independent third-party pricing service estimates fair value using models employing techniques such as discounted cash flow analyses. The assumptions used in these models typically include assumptions for interest rates, credit losses, and prepayments, utilizing market observable data where available. (c) Federal Home Loan Bank of New York Stock The fair value for Federal Home Loan Bank of New York (FHLB) stock is its carrying value, since this is the amount for which it could be redeemed and there is no active market for this stock. (d) Loans (Held-for-Investment) Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as originated and purchased, and further segregated by residential mortgage, construction, land, multifamily, commercial and consumer. Each loan category is further segmented into amortizing and non-amortizing and fixed and adjustable rate interest terms and by performing and nonperforming categories. The fair value of loans is estimated by discounting the future cash flows using current prepayment assumptions and current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. This method of estimating fair value does not incorporate the exit price concept of fair value prescribed by the FASB ASC Topic for Fair Value Measurements and Disclosures. (e) Loans (Held-for-Sale) Held-for-sale loans are carried at the lower of aggregate cost or estimated fair value, less costs to sell, and therefore fair value is equal to carrying value. (f) Deposits The fair value of deposits with no stated maturity, such as non-interest bearing demand deposits, savings, NOW and money market accounts, is equal to the amount payable on demand. The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. (g) Commitments to Extend Credit and Standby Letters of Credit The fair value of commitments to extend credit and standby letters of credit is 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 of off‑balance sheet commitments is insignificant and therefore not included in the following table. (h) Borrowed Funds The fair value of borrowed funds is estimated by discounting future cash flows based on rates currently available for debt with similar terms and remaining maturity. (i) Advance Payments by Borrowers for Taxes and Insurance Advance payments by borrowers for taxes and insurance have no stated maturity; the fair value is equal to the amount currently payable. The estimated fair value of the Company’s significant financial instruments at June 30, 2017 , and December 31, 2016 , is presented in the following tables (in thousands): June 30, 2017 Estimated Fair Value Carrying Value Level 1 Level 2 Level 3 Total Financial assets: Cash and cash equivalents $ 50,299 $ 50,299 $ — $ — $ 50,299 Trading securities 8,808 8,808 — — 8,808 Securities available-for-sale 473,009 314 472,695 — 473,009 Securities held-to-maturity 10,039 — 10,021 — 10,021 Federal Home Loan Bank of New York stock, at cost 26,855 — 26,855 — 26,855 Loans held-for-sale 2,009 — — 2,009 2,009 Net loans held-for-investment 3,022,310 — — 3,020,974 3,020,974 Financial liabilities: Deposits $ 2,678,473 $ — $ 2,681,014 $ — $ 2,681,014 Borrowed funds 500,690 — 499,220 — 499,220 Advance payments by borrowers for taxes and insurance 15,293 — 15,293 — 15,293 December 31, 2016 Estimated Fair Value Carrying Value Level 1 Level 2 Level 3 Total Financial assets: Cash and cash equivalents $ 96,085 $ 96,085 $ — $ — $ 96,085 Trading securities 7,857 7,857 — — 7,857 Securities available-for-sale 498,897 271 498,626 — 498,897 Securities held-to-maturity 10,148 — 10,118 — 10,118 Federal Home Loan Bank of New York stock, at cost 25,123 — 25,123 — 25,123 Net loans held-for-investment 2,943,489 — — 2,970,438 2,970,438 Financial liabilities: Deposits $ 2,713,587 $ — $ 2,720,176 $ — $ 2,720,176 Borrowed funds 473,206 — 472,387 — 472,387 Advance payments by borrowers for taxes and insurance 12,331 — 12,331 — 12,331 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 losses, 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. 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.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of shares outstanding during the period. For purposes of calculating basic earnings per share, weighted average common shares outstanding excludes unallocated employee stock ownership plan (“ESOP”) shares that have not been committed for release and unvested restricted stock. Diluted earnings per share is computed using the same method as basic earnings per share, but reflects the potential dilution that could occur if stock options and unvested shares of restricted stock were exercised and converted into common stock. These potentially dilutive shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method. In March 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, a new standard that simplifies certain aspects of accounting for share-based payments. The Company adopted ASU No. 2016-09 effective for the first quarter of 2017. The update amended the diluted earnings per share calculation in that excess tax benefits are no longer included in assumed proceeds when determining average diluted shares outstanding under the treasury stock method. This guidance is required to be applied prospectively upon adoption. For further discussion, see Note 10 - “Recently Issued and Adopted Accounting Pronouncements”. When applying the treasury stock method for the three and six months ended June 30, 2017, we added (1) the assumed proceeds from option exercises and (2) the average unamortized compensation costs related to unvested shares of restricted stock and stock options. We then divided this sum by our average stock price for the period to calculate assumed shares repurchased. The excess of the number of shares issuable over the number of shares assumed to be repurchased is added to basic weighted average common shares to calculate diluted earnings per share. For the three and six months ended June 30, 2016, we added (1) the assumed proceeds from option exercises; (2) the tax benefit, that would have been credited to additional paid-in capital assuming exercise of non-qualified stock options and vesting of shares of restricted stock; and (3) the average unamortized compensation costs related to unvested shares of restricted stock and stock options. We then divided this sum by our average stock price for the period to calculate assumed shares repurchased. The excess of the number of shares issuable over the number of shares assumed to be repurchased is added to basic weighted average common shares to calculate diluted earnings per share. The following is a summary of the Company’s earnings per share calculations and reconciliation of basic to diluted earnings per share for the periods indicated (dollars in thousands, except per share data): Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Net income available to common stockholders $ 8,410 $ 6,985 $ 18,358 $ 10,645 Weighted average shares outstanding-basic 45,252,136 44,350,458 45,137,791 44,144,434 Effect of non-vested restricted stock and stock options outstanding 1,579,226 1,302,740 1,741,467 1,327,143 Weighted average shares outstanding-diluted 46,831,362 45,653,198 46,879,258 45,471,577 Earnings per share-basic $ 0.19 $ 0.16 $ 0.41 $ 0.24 Earnings per share-diluted $ 0.18 $ 0.15 $ 0.39 $ 0.23 Anti-dilutive shares 50,000 1,032,080 45,000 1,021,740

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued and Adopted Accounting Pronouncements	Recently Issued and Adopted Accounting Pronouncements Accounting Pronouncements Adopted In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , a new standard that simplifies certain aspects of accounting for share-based payments. The amendments include the following: • Excess tax benefits and deficiencies resulting from exercise or vesting of stock awards are recorded as income tax expense or benefit on the income statement. Previously, excess tax benefits and certain tax deficiencies were recorded as equity in additional paid-in capital. This update is required to be applied prospectively upon adoption. • For diluted earnings per share calculations, excess tax benefits are no longer included in assumed proceeds when determining average diluted shares outstanding under the treasury stock method, resulting in changes to average diluted shares outstanding. This update is required to be applied prospectively upon adoption. • Excess tax benefits or deficiencies are included as income tax expense as discrete items in the period in which they occur, which impact the effective tax rate in each reporting period; however, these discrete items are not included in the projected annual effective tax rate calculation. This update is required to be applied prospectively upon adoption. • Excess tax benefits are presented as cash flows from operating activities. Previously, excess tax benefits were included as a cash inflow from financing activities. This update may be applied either prospectively or retrospectively upon adoption. The Company applied this update prospectively upon adoption and prior periods have not been adjusted. • Cash paid by an employer to taxing authorities when withholding shares for tax withholding purposes is presented as cash outflows from financing activities, which is consistent with the manner in which we have presented such employee withholding taxes in the past. Accordingly, no reclassification for prior periods is required. Beginning in 2017, the Company no longer withholds shares for tax withholding purposes and employees pay their own taxes. • An accounting policy election, using a modified retrospective transition method, to account for forfeitures as they occur or estimate the number of awards expected to be forfeited. The Company elected to account for forfeitures as they occur. The Company adopted ASU No. 2016-09 effective for the first quarter of 2017 and upon adoption recorded a cumulative effect adjustment of $2.9 million to the opening balances of retained earnings and additional paid-in-capital. Adoption of ASU No. 2016-09 resulted in the recognition of a $593,000 and $2.3 million benefit within income tax expense for the three and six months ended June 30, 2017, respectively, which resulted in a corresponding increase to net income and earnings per share ( $0.01 and $0.05 per diluted share, for the three and six months ended June 30, 2017, respectively). In addition, the guidance increases average diluted shares, since the Company no longer includes such excess tax benefits in the calculation of diluted shares. Adoption of this update does not affect the Company's or the Bank's total equity, book value per share, or regulatory capital ratios. Accounting Pronouncements Not yet Adopted In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU simplifies the subsequent measurement of goodwill impairment by eliminating the requirement to calculate the implied fair value of goodwill (i.e., the current Step 2 of the goodwill impairment test) to measure a goodwill impairment charge. As amended, the goodwill impairment test will consist of one step comparing the fair value of a reporting unit with its carrying amount. A goodwill impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. The ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim and annual goodwill impairment testing dates after January 1, 2017. The adoption of this pronouncement is not expected to have a material effect on the Company's consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , which requires that entities include restricted cash and restricted cash equivalents with cash and cash equivalents in the beginning-of-period and end-of-period total amounts shown on the Statement of Cash Flows. Prior to this pronouncement there was no guidance on how to present restricted cash and cash equivalents in the Statement of Cash Flows. ASU No. 2016-18 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and is required to be applied retrospectively to all periods presented beginning in the year of adoption. The adoption of this pronouncement is not expected to have a material effect on the Company's consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , which provides guidance on the classification of certain cash receipts and payments within the statement of cash flows. ASU No. 2016-15 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and is required to be applied retrospectively to all periods presented beginning in the year of adoption. Since the ASU only impacts classification on the statements of cash flows, adoption will not affect the Company's consolidated financial position, results of operations or its cash and cash equivalents. In June 2016, the FASB issued No. ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (CECL) model). Under this model, entities will estimate credit losses over the entire contractual term of the instrument from the date of initial recognition of that instrument. Current US GAAP is based on an incurred loss model that delays recognition of credit losses until it is probable the loss has been incurred. Accordingly, it is anticipated that credit losses will be recognized earlier under the CECL model than under the incurred loss model. ASU No. 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019. The Company is currently evaluating the potential effect of adoption of this pronouncement on its consolidated financial statements, but the extent of the effect is indeterminable at this time as it will depend upon the nature and characteristics of the Company's loan portfolio at the adoption date, as well as economic conditions and forecasts at that date. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which is intended to increase transparency and comparability of accounting for lease transactions. The ASU will require all leases to be recognized on the balance sheet as lease assets and lease liabilities and will require both quantitative and qualitative disclosures regarding key information about leasing arrangements. Lessor accounting is largely unchanged. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within that reporting period. The Company is currently evaluating the potential effect of adoption of this pronouncement on its consolidated financial statements by reviewing its existing lease contracts and service contracts that may include embedded leases. The Company expects a gross-up of its consolidated balance sheet as a result of recognizing lease liabilities and right of use assets; the extent of such gross-up is under evaluation. The Company does not expect material changes to the recognition of operating lease expense in its consolidated statements of comprehensive income. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , which addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The guidance primarily affects the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged. ASU No. 2016-01 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The adoption of this pronouncement is not expected to have a material effect on the Company's consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will be effective for interim and annual periods beginning after December 15, 2017 and will replace most existing revenue recognition guidance in U.S. GAAP. The Company does not expect the guidance to have a material effect on its consolidated financial statements as the ASU is not applicable to financial instruments and, therefore, will not affect the majority of the Company's revenues.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Reclassification	Whenever necessary, certain prior year amounts are reclassified to conform to the current year presentation.
Basis of Accounting	In preparing the unaudited consolidated financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP), management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated statements of financial condition and results of operations for the periods indicated.
Use of Estimates	Material estimates that are particularly susceptible to change are: the allowance for loan losses, the evaluation of goodwill and other intangible assets, impairment on investment securities, fair value measurements of assets and liabilities, and income taxes. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual amounts or results could differ significantly from those estimates.
Fair Value Measurements	Fair Value Measurements The following tables present the assets reported on the consolidated balance sheet at their estimated fair value as of June 30, 2017 , and December 31, 2016 , by level within the fair value hierarchy as required by the Fair Value Measurements and Disclosures Topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC). Financial assets and liabilities are classified in their entirety based on the level of input that is significant to the fair value measurement. The fair value hierarchy is as follows: • Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. • Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlations or other means. • Level 3 Inputs – Significant unobservable inputs that reflect the Company’s own assumptions that market participants would use in pricing the assets or liabilities.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The FASB ASC Topic for Financial Instruments requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or non-recurring basis are discussed above. The following methods and assumptions were used to estimate the fair value of other financial assets and financial liabilities not already discussed above: (a) Cash, Cash Equivalents, and Certificates of Deposit Cash and cash equivalents are short-term in nature with original maturities of six months or less; the carrying amount approximates fair value. Certificates of deposit having original terms of six-months or less; the carrying value generally approximates fair value. Certificates of deposit with an original maturity of six months or greater; the fair value is derived from discounted cash flows. (b) Securities (Held to Maturity) The estimated fair values for substantially all of our securities are obtained from an independent nationally recognized pricing service. The independent pricing service utilizes market prices of same or similar securities whenever such prices are available. Prices involving distressed sellers are not utilized in determining fair value. Where necessary, the independent third-party pricing service estimates fair value using models employing techniques such as discounted cash flow analyses. The assumptions used in these models typically include assumptions for interest rates, credit losses, and prepayments, utilizing market observable data where available. (c) Federal Home Loan Bank of New York Stock The fair value for Federal Home Loan Bank of New York (FHLB) stock is its carrying value, since this is the amount for which it could be redeemed and there is no active market for this stock. (d) Loans (Held-for-Investment) Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as originated and purchased, and further segregated by residential mortgage, construction, land, multifamily, commercial and consumer. Each loan category is further segmented into amortizing and non-amortizing and fixed and adjustable rate interest terms and by performing and nonperforming categories. The fair value of loans is estimated by discounting the future cash flows using current prepayment assumptions and current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. This method of estimating fair value does not incorporate the exit price concept of fair value prescribed by the FASB ASC Topic for Fair Value Measurements and Disclosures. (e) Loans (Held-for-Sale) Held-for-sale loans are carried at the lower of aggregate cost or estimated fair value, less costs to sell, and therefore fair value is equal to carrying value. (f) Deposits The fair value of deposits with no stated maturity, such as non-interest bearing demand deposits, savings, NOW and money market accounts, is equal to the amount payable on demand. The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. (g) Commitments to Extend Credit and Standby Letters of Credit The fair value of commitments to extend credit and standby letters of credit is 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 of off‑balance sheet commitments is insignificant and therefore not included in the following table. (h) Borrowed Funds The fair value of borrowed funds is estimated by discounting future cash flows based on rates currently available for debt with similar terms and remaining maturity. (i) Advance Payments by Borrowers for Taxes and Insurance Advance payments by borrowers for taxes and insurance have no stated maturity; the fair value is equal to the amount currently payable.
Earnings Per Share	Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of shares outstanding during the period. For purposes of calculating basic earnings per share, weighted average common shares outstanding excludes unallocated employee stock ownership plan (“ESOP”) shares that have not been committed for release and unvested restricted stock. Diluted earnings per share is computed using the same method as basic earnings per share, but reflects the potential dilution that could occur if stock options and unvested shares of restricted stock were exercised and converted into common stock. These potentially dilutive shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method. In March 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, a new standard that simplifies certain aspects of accounting for share-based payments. The Company adopted ASU No. 2016-09 effective for the first quarter of 2017. The update amended the diluted earnings per share calculation in that excess tax benefits are no longer included in assumed proceeds when determining average diluted shares outstanding under the treasury stock method. This guidance is required to be applied prospectively upon adoption. For further discussion, see Note 10 - “Recently Issued and Adopted Accounting Pronouncements”. When applying the treasury stock method for the three and six months ended June 30, 2017, we added (1) the assumed proceeds from option exercises and (2) the average unamortized compensation costs related to unvested shares of restricted stock and stock options. We then divided this sum by our average stock price for the period to calculate assumed shares repurchased. The excess of the number of shares issuable over the number of shares assumed to be repurchased is added to basic weighted average common shares to calculate diluted earnings per share. For the three and six months ended June 30, 2016, we added (1) the assumed proceeds from option exercises; (2) the tax benefit, that would have been credited to additional paid-in capital assuming exercise of non-qualified stock options and vesting of shares of restricted stock; and (3) the average unamortized compensation costs related to unvested shares of restricted stock and stock options. We then divided this sum by our average stock price for the period to calculate assumed shares repurchased. The excess of the number of shares issuable over the number of shares assumed to be repurchased is added to basic weighted average common shares to calculate diluted earnings per share.
Recently Issued and Adopted Accounting Pronouncements	Recently Issued and Adopted Accounting Pronouncements Accounting Pronouncements Adopted In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , a new standard that simplifies certain aspects of accounting for share-based payments. The amendments include the following: • Excess tax benefits and deficiencies resulting from exercise or vesting of stock awards are recorded as income tax expense or benefit on the income statement. Previously, excess tax benefits and certain tax deficiencies were recorded as equity in additional paid-in capital. This update is required to be applied prospectively upon adoption. • For diluted earnings per share calculations, excess tax benefits are no longer included in assumed proceeds when determining average diluted shares outstanding under the treasury stock method, resulting in changes to average diluted shares outstanding. This update is required to be applied prospectively upon adoption. • Excess tax benefits or deficiencies are included as income tax expense as discrete items in the period in which they occur, which impact the effective tax rate in each reporting period; however, these discrete items are not included in the projected annual effective tax rate calculation. This update is required to be applied prospectively upon adoption. • Excess tax benefits are presented as cash flows from operating activities. Previously, excess tax benefits were included as a cash inflow from financing activities. This update may be applied either prospectively or retrospectively upon adoption. The Company applied this update prospectively upon adoption and prior periods have not been adjusted. • Cash paid by an employer to taxing authorities when withholding shares for tax withholding purposes is presented as cash outflows from financing activities, which is consistent with the manner in which we have presented such employee withholding taxes in the past. Accordingly, no reclassification for prior periods is required. Beginning in 2017, the Company no longer withholds shares for tax withholding purposes and employees pay their own taxes. • An accounting policy election, using a modified retrospective transition method, to account for forfeitures as they occur or estimate the number of awards expected to be forfeited. The Company elected to account for forfeitures as they occur. The Company adopted ASU No. 2016-09 effective for the first quarter of 2017 and upon adoption recorded a cumulative effect adjustment of $2.9 million to the opening balances of retained earnings and additional paid-in-capital. Adoption of ASU No. 2016-09 resulted in the recognition of a $593,000 and $2.3 million benefit within income tax expense for the three and six months ended June 30, 2017, respectively, which resulted in a corresponding increase to net income and earnings per share ( $0.01 and $0.05 per diluted share, for the three and six months ended June 30, 2017, respectively). In addition, the guidance increases average diluted shares, since the Company no longer includes such excess tax benefits in the calculation of diluted shares. Adoption of this update does not affect the Company's or the Bank's total equity, book value per share, or regulatory capital ratios. Accounting Pronouncements Not yet Adopted In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.

Early adoption is permitted for interim and annual goodwill impairment testing dates after January 1, 2017. The adoption of this pronouncement is not expected to have a material effect on the Company's consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , which requires that entities include restricted cash and restricted cash equivalents with cash and cash equivalents in the beginning-of-period and end-of-period total amounts shown on the Statement of Cash Flows. Prior to this pronouncement there was no guidance on how to present restricted cash and cash equivalents in the Statement of Cash Flows. ASU No. 2016-18 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and is required to be applied retrospectively to all periods presented beginning in the year of adoption. The adoption of this pronouncement is not expected to have a material effect on the Company's consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , which provides guidance on the classification of certain cash receipts and payments within the statement of cash flows. ASU No. 2016-15 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and is required to be applied retrospectively to all periods presented beginning in the year of adoption. Since the ASU only impacts classification on the statements of cash flows, adoption will not affect the Company's consolidated financial position, results of operations or its cash and cash equivalents.

The ASU will be effective for interim and annual periods beginning after December 15, 2017 and will replace most existing revenue recognition guidance in U.S. GAAP. The Company does not expect the guidance to have a material effect on its consolidated financial statements as the ASU is not applicable to financial instruments and, therefore, will not affect the majority of the Company's revenues.
