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 nine months ended September 30, 2014, are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2014.  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/A for the year ended December 31, 2013, of Northfield Bancorp, Inc. as filed with the SEC.

The Company held 14 pass-through mortgage-backed securities issued or guaranteed by GSEs, 19 REMIC mortgage-backed securities issued or guaranteed by GSEs, and two REMIC mortgage-backed securities not issued or guaranteed by GSEs that were in a continuous unrealized loss position of greater than twelve months at September 30, 2014.  There were eight pass-through mortgage-backed securities issued or guaranteed by GSEs and four REMIC mortgage-backed securities issued or guaranteed by GSEs that were in an unrealized loss position of less than twelve months at September 30, 2014. All securities referred to above were rated investment grade at September 30, 2014.  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.

The Company monitors the credit quality of its loans by reviewing certain key 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 help management monitor the credit quality of the Company’s loans.  Loan-to-value ratios used by management in monitoring credit quality are based on current period loan balances and original values at time of origination (unless a more current appraisal has been obtained).  In calculating the provision for loan losses, management has determined that commercial real estate loans and multifamily loans having loan-to-value ratios of less than 35%, and one-to-four family loans having loan-to-value ratios 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.  When the lending officer learns of important financial developments, the risk rating is reviewed and adjusted if necessary.  Periodically, management presents monitored assets to the Board 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 in confirming the adequacy of the allowance for loan losses.  After determining the general reserve loss factor for each portfolio segment, the portfolio segment 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.  Loans collectively evaluated for impairment that have an internal credit rating of special mention or substandard are multiplied by a multiple of the general reserve loss factors for each 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 through 5 are considered pass ratings.  An asset is considered 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 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 designated special mention.

Included in originated and acquired loans receivable (including 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 nonaccrual loans was $14.0 million and $17.8 million at September 30, 2014, and December 31, 2013, respectively. Generally, loans are placed on non-accruing status when they become 90 days or more delinquent, 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 $10.4 million and $13.5 million at September 30, 2014, and December 31, 2013, 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 $3.5 million and $3.8 million at September 30, 2014, and December 31, 2013, respectively.  There were no loans held-for-sale at September 30, 2014. Non-accrual amounts included in loans held-for-sale at December 31, 2013, were $471,000.  Loans past due 90 days or more and still accruing interest were $418,000 and $32,000 at September 30, 2014, and December 31, 2013, respectively, and consisted of loans that are considered well secured and in the process of collection.
The following tables set forth the detail, and delinquency status, of non-performing loans (non-accrual loans and loans past due 90 days or more and still accruing), net of deferred fees and costs, at September 30, 2014, and December 31, 2013, excluding loans held-for-sale (in thousands).  The following table excludes PCI loans at September 30, 2014, and December 31, 2013, which have been segregated into pools in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Subtopic 310-30.  Each loan pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. At September 30, 2014, expected future cash flows of each PCI loan pool were consistent with those estimated in our most recent recast of the cash flows.

Included in the above table at September 30, 2014, are loans with carrying balances of $11.0 million that were not written down by either charge-offs or specific reserves in our allowance for loan losses.  Included in the above table at December 31, 2013, are loans with carrying balances of $21.8 million that were not written down by either charge-offs or specific reserves in our allowance for loan losses.  Loans not written down by charge-offs or specific reserves at September 30, 2014, and December 31, 2013, are considered to have sufficient collateral values, less costs to sell, to support the carrying balances of the loans.
The average recorded balance of originated impaired loans for the nine months ended September 30, 2014 and 2013, was $35.5 million and $47.0 million, respectively.  The Company recorded $417,000 and $1.3 million of interest income on impaired loans for the three and nine months ended September 30, 2014, respectively, as compared to $424,000 and $1.5 million of interest income on impaired loans for the three and nine months ended September 30, 2013, respectively.
There were no loans modified as troubled debt restructurings during the nine months ended September 30, 2014. The following tables summarize loans that were modified as troubled debt restructurings during the nine months ended September 30, 2013.

All of the relationships in the table above were restructured to receive reduced interest rates.
At September 30, 2014, and December 31, 2013, we had troubled debt restructurings of $34.3 million and $36.8 million, respectively.
Management classifies all troubled debt restructurings 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 consider recent market conditions appropriately, 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 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 September 30, 2014, no TDR loan that was restructured during the twelve months ended September 30, 2014 had subsequently defaulted.

The Plan provides for the issuance or delivery of up to 4,978,249 shares (1,422,357 restricted shares and 3,555,892 stock options) of Northfield Bancorp, Inc. common stock subject to certain Plan limitations.
	All stock options and restricted stock granted to date vest in equal installments over a five-year period beginning one year from the date of grant. The vesting of options and restricted stock awards may accelerate in accordance with terms of the Plan. Stock options were granted at an exercise price equal to the fair value of the Company’s common stock on the grant date based on quoted market prices and all have an expiration period of ten years. The fair value of stock options granted on June 11, 2014, was estimated utilizing the Black-Scholes option pricing model using the following assumptions: an expected life of 6.5 years, risk-free rate of return of 1.92%, volatility of 33.83% and a dividend yield of 1.83%.
	The following table is a summary of the Company’s stock options outstanding as of September 30, 2014, and changes therein during the nine months then ended:
		Number of Stock Options		Weighted Average Grant Date Fair Value		Weighted Average Exercise Price		Weighted Average Contractual Life (years)

	Fair Value Measurements
	The following tables present the assets reported on the consolidated balance sheet at their estimated fair value as of September 30, 2014, and December 31, 2013, by level within the fair value hierarchy as required by the Fair Value Measurements and Disclosures Topic of the FASB 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				Valuation Methodology		Unobservable Inputs	Range of Inputs
	September 30, 2014		December 31, 2013					September 30, 2014		December 31, 2013

Other real estate owned	$	491	$	634	Appraisals		Discount for costs to sell	7.00%		7.00%
Available for Sale Securities: The estimated fair values for mortgage-backed and corporate 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, classified as Level 1, are derived from quoted market prices in active markets.  Equity securities consist of publicly traded mutual funds.  There were no transfers of securities between Level 1 and Level 2 during the three months ended September 30, 2014.
Trading Securities: Fair values are derived from quoted market prices in active markets.  The assets consist of publicly traded mutual funds.
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.
Impaired Loans: At September 30, 2014, and December 31, 2013, the Company had originated impaired loans held-for-investment and held-for-sale with outstanding principal balances of $26.5 million and $31.7 million, respectively, that were recorded at their estimated fair value of $23.2 million and $27.6 million, respectively.  The Company recorded net impairment charges of $146,000 for the nine months ended September 30, 2014, and net impairment recoveries of $824,000 for the nine months ended September 30, 2013, and net charge-offs of $348,000 and $821,000 for the nine months ended September 30, 2014 and 2013, respectively, 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 September 30, 2014, and December 31, 2013, the Company had assets acquired through foreclosure, or deed in lieu of foreclosure, of $491,000 and $634,000, respectively.  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.
There was a $257,000 subsequent valuation adjustment to one OREO property for the three months ended September 30, 2014.  Operating costs after acquisition are expensed.
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)	Borrowings
The fair value of borrowings 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
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 September 30, 2014, and December 31, 2013, is presented in the following tables (in thousands):

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 are included in the weighted average number of shares outstanding for the period using the treasury stock method.  When applying the treasury stock method, we add: (1) the assumed proceeds from option exercises; (2) the tax benefit, if any, 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 divide 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):

	Recent Accounting Pronouncements
	In January 2014, the FASB issued ASU No. 2014-04, “Receivables - Troubled Debt Restructurings by Creditors (subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.” This ASU clarifies that if an in-substance repossession occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure, or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal arrangement. This ASU will require interim and annual disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU No. 2014-04 is effective for annual and interim periods beginning after December 15, 2014. The Company’s adoption of this pronouncement is not expected to have a material impact on the Company’s consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” This ASU supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the codification. This update will be effective for interim and annual periods beginning after December 15, 2016. The Company is still assessing the impact of this pronouncement, but does not expect the guidance to have a material impact on the Company's consolidated financial statements.
	For the three and nine months ended September 30, 2014, there were no other new accounting pronouncements that would materially impact the Company's consolidated financial statements.
