Organization, Consolidation and Presentation of Financial Statements [Abstract]

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 months ended March 31, 2019 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2019 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, estimated cash flows of our purchased credit-impaired (“PCI”) loans 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, 2018, of the Company as filed with the SEC.

Fair Value Measurements

The following tables present the assets reported on the consolidated balance sheets at their estimated fair value as of March 31, 2019, and December 31, 2018, 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

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 and Cash Equivalents

Cash and cash equivalents are short-term in nature with original maturities of three 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)	Debt 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 analysis. The assumptions used in these models typically include assumptions for interest rates, credit losses, and prepayments, utilizing market observable data where available.


(c)	Investments in Equity Securities at Net Asset Value Per Share

The Company uses net asset value as a practical expedient to record its investment in a private SBA Loan Fund since the shares in the fund are not publicly traded, do not have a readily determinable fair value and the net asset value per share is calculated in a manner consistent with the measurement principles of an investment company.


(d)	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.


(e)	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 using a discounted cash flow analysis. The discount rates used to determine fair value use interest rate spreads that reflect factors such as liquidity, credit, and nonperformance risk of the loans.


(f)	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.


(g)	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.


(h)	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.


(i)	Borrowings

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.


(j)	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. When applying the treasury stock method we added the assumed proceeds from option exercises and 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

Recent Accounting Pronouncements

Accounting Pronouncements Adopted

ASU No. 2016-02. In February 2016, the FASB issued ASU No. 2016-02, Leases (“Topic 842”), which requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date for leases classified as operating leases as well as finance leases. Under this guidance, lessor accounting is largely unchanged. This ASU became effective for annual and interim periods for the Company on January 1, 2019. The Company adopted the standard by applying the alternative transition method whereby comparative periods were not restated, and no cumulative effect adjustment to the opening balance of retained earnings was recognized as of January 1, 2019. The Company also elected the ASU’s package of three practical expedients, which allowed the Company to forego a reassessment of (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) the initial direct costs for any existing leases. The Company also elected not to apply the recognition requirements of the ASU to any short-term leases (as defined by related accounting guidance) and will account for lease and non-lease components separately because such amounts are readily determinable under most lease contracts. The adoption of this standard resulted in the Company recognizing operating lease right-of-use assets and related operating lease liabilities totaling $43.6 million and $47.3 million respectively, as of January 1, 2019. The adoption of this ASU did not have a material impact on the Company’s consolidated results of operations. See Note 10, Leases, for further disclosures.

ASU No. 2017-08. In March 2017, the FASB issued ASU No. 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in this update require the premium on callable debt securities to be amortized to the earliest call date rather than the maturity date; however, securities held at a discount continue to be amortized to maturity. The amendments apply only to debt securities purchased at a premium that are callable at fixed prices and on preset dates. The amendments more closely align interest income recorded on debt securities held at a premium or discount with the economics of the underlying instrument. This ASU became effective for the Company on January 1, 2019, and did not have a material impact on the Company's consolidated financial statements.

ASU No. 2018-07. In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which is intended to align the accounting for share-based payment awards issued to employees and nonemployees. The guidance applies to nonemployee awards issued in exchange for goods or services used or consumed in an entity’s own operations and to awards granted by an investor to employees and nonemployees of an equity method investee for goods or services used or consumed in the investee’s operations. There are no new disclosure requirements. This ASU became effective for the Company on January 1, 2019. Adoption of this ASU did not have an impact on the Company's consolidated financial statements, as share-based payment awards to nonemployee Directors are accounted for in the same manner as share-based payment awards for employees.

Accounting Pronouncements Not Yet Adopted

ASU No. 2018-15. In August 2018, the FASB issued ASU No. 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract.” This guidance aligns the accounting for implementation costs related to a hosting arrangement that is a service contract with the guidance on capitalizing costs associated with developing or obtaining internal-use software. Specifically, where a cloud computing arrangement includes a license to internal-use software, the software license is accounted for by the customer in accordance with Subtopic 350-40, “Intangibles - Goodwill and Other-Internal-Use Software”. ASU No. 2018-15 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. ASU No. 2018-15 is not expected to have a material impact on the Company’s Consolidated Financial Statements.

ASU No. 2018-14. In August 2018, the FASB issued ASU No. 2018-14, “Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans.” This ASU makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. ASU 2018-14 is effective for fiscal years ending after December 15, 2020; early adoption is permitted. As ASU 2018-14 only revises disclosure requirements, it will not have an impact on the Company’s Consolidated Financial Statements.

ASU No 2017-04. 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 an effect on the Company's consolidated financial statements.

ASU No. 2016-13. 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; early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018. The Company continues to evaluate the potential effect of adoption of this pronouncement on its consolidated financial statements by identifying key interpretive issues, assessing its processes, portfolio segmentation, model development, and identifying the data and system requirements against the guidance to determine what modifications may be required. As part of the evaluation process, the Company has established a CECL cross-function working group that includes individuals from various functional areas to assess processes and has also contracted with a third-party vendor to implement enhanced modeling techniques that incorporate the loss measurement requirements in these amendments as part of adopting the ASU. The adoption of ASU No. 2016-13 may result in an increase in the allowance for loan losses as a result of changing from an incurred loss model, which encompasses allowances for current known and inherent losses within the portfolio, to an expected losses model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. However, as the impact of adopting the new guidance is expected to be heavily influenced by an assessment of the composition, characteristics, and credit quality of the Company’s loan portfolio as well as the economic conditions in effect at the adoption date, management is currently unable to reasonably estimate the impact of adopting the new standard.
