Notes to Unaudited Consolidated Financial Statements

Note 1 – 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, 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.

Note 2 – 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 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

NORTHFIELD BANCORP, INC.

Notes to Unaudited Consolidated Financial Statements - (Continued)

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.

The Company held 21 pass-through mortgage-backed securities issued or guaranteed by GSEs, nine REMIC mortgage-backed securities issued or guaranteed by GSEs, and one REMIC mortgage-backed security not issued or guaranteed by a GSE that were in a continuous unrealized loss position of twelve months or greater at September 30, 2017. There were 17 pass-through mortgage-backed securities issued or guaranteed by GSEs, 25 REMIC mortgage-backed securities issued or guaranteed by a GSE, and eight corporate bonds that were in an unrealized loss position of less than twelve months at September 30, 2017. All securities referred to above were rated investment grade at September 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.

Contractual maturities for mortgage-backed securities are not presented, as expected maturities on mortgage‑backed securities may differ from contractual maturities as borrowers may have the right to call or prepay obligations with or without penalties. There were no sales of held-to-maturity securities for the three and nine months ended September 30, 2017, or September 30, 2016. The Company did not recognize any other-than-temporary impairment charges in earnings on securities held-to-maturity during the three and nine months ended September 30, 2017, or September 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 September 30, 2017 and December 31, 2016, were as follows (in thousands):



	September 30, 2017				December 31, 2016

Total securities held-to-maturity	$	29	$	3,772	$	59	$	7,466

The Company held two 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 September 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.

Notes to Unaudited Consolidated Financial Statements - (Continued)

The Company monitors the credit quality of its loan portfolio on 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.

Notes to Unaudited Consolidated Financial Statements - (Continued)

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 $5.5 million and $7.3 million at September 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 September 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 September 30, 2017, and December 31, 2016, respectively. There were no non-accrual loans held-for-sale at September 30, 2017 and December 31, 2016. Loans past due 90 days or more and still accruing interest were $173,000 and $60,000 at September 30, 2017, and December 31, 2016, respectively, and consisted of loans that are considered well secured and in the process of collection.

Notes to Unaudited Consolidated Financial Statements - (Continued)

There were no loans modified as troubled debt restructurings (TDRs) during the three months ended September 30, 2017. There was one one-to-four family residential loan modified as a TDR during the nine months ended September 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 nine months ended September 30, 2016.

At September 30, 2017, and December 31, 2016, we had TDRs of $21.7 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 an 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 management firm that specializes 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 September 30, 2017, there was one TDR loan that was restructured during the preceding twelve months ended September 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 September 30, 2017. At September 30, 2016, there were three TDR loans that were restructured during the twelve months ended September 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 delinquent and on accrual status, and two one-to-four family residential loans with a recorded investment of $361,000, which were 90 days or more past due and on non-accrual status.

Note 8 – Fair Value Measurements

The following tables present the assets reported on the consolidated balance sheet at their estimated fair value as of September 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.

Notes to Unaudited Consolidated Financial Statements - (Continued)

The valuation techniques described below were used to measure fair value of financial instruments in the tables below on a recurring basis and a non-recurring basis as of September 30, 2017 and December 31, 2016.

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 nine months ended September 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 September 30, 2017, and December 31, 2016, the Company had impaired loans held-for-investment (excluding PCI loans) with outstanding principal balances of $9.0 million and $17.7 million, respectively, which were recorded at their estimated fair value of $6.6 million and $14.5 million, respectively. The Company recorded a net decrease in the specific reserve for impaired loans of $246,000 and $24,000 for the nine months ended September 30, 2017, and September 30, 2016, 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 both September 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 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.

Notes to Unaudited Consolidated Financial Statements - (Continued)


(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.

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.

Note 9 – 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 nine months ended September 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 nine months ended September 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):

Note 10 – 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.

Table of Contents

NORTHFIELD BANCORP, INC.

Notes to Unaudited Consolidated Financial Statements - (Continued)


•	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 also resulted in the recognition of a $2.3 million benefit within income tax expense for the nine months ended September 30, 2017, which resulted in a corresponding increase to net income and earnings per share. 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

Table of Contents

NORTHFIELD BANCORP, INC.

Notes to Unaudited Consolidated Financial Statements - (Continued)

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 adoption of this pronouncement to have a material impact on its results of operations.

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 using a five-step model that requires entities to exercise judgment when considering the terms of the contracts. ASU No. 2014-09 and subsequent related updates, also require new qualitative and quantitative disclosures, including disaggregation of revenues and descriptions of performance obligations. The Company will adopt the guidance in the first quarter of 2018 using the modified retrospective method with a cumulative-effect adjustment to opening retained earnings. Because the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other U.S. GAAP, the new revenue recognition standard will not have a material impact on the company's consolidated financial statements. The Company's implementation efforts include the identification of revenue streams within the scope of the guidance, as well as the evaluation of revenue contracts. Although the impact of adoption is not expected to be significant to the financial statements, the guidance includes expanded disclosures to revenue which we are currently in the process of drafting.

Note 11 – Commitments

The Company has obligations related to non-cancelable operating leases and capitalized leases on property used for banking purposes, that were disclosed in its Annual Report on Form 10-K for the year ended December 31, 2016. During the quarter ended September 30, 2017, the Company amended the terms of one contract, and entered into a new contract which resulted in additional aggregate minimum rent obligations totaling approximately $12.4 million as follows: (1) In July 2017, the Company entered into an amendment to the operating lease for its main office premises in Woodbridge, New Jersey, to lease an additional 6,919 square feet of office space in the same building and extend the lease term by 10 years and eight months from July 1, 2018 through February 28, 2029. Pursuant to the lease amendment, we estimate our total additional future minimum rent payments to be approximately $9.9 million and (2) In September 2017, the Company entered into a new lease agreement for 3,600 square feet of office space at a branch facility in Staten Island, New York, for a term of 15 years through September 2032. Pursuant to the terms of this lease we estimate our total additional future minimum rent payments to be approximately $2.5 million.

Critical Accounting Policies

Note 1 to the Company’s Audited Consolidated Financial Statements for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K, as supplemented by this report, contains a summary of significant accounting policies. Various elements of these accounting policies, by their nature, are inherently subject to estimation techniques, valuation assumptions and other subjective assessments. Certain assets are carried in the Consolidated Balance Sheets at estimated fair value or the lower of cost or estimated fair value. Policies with respect to the methodologies used to determine the allowance for loan losses, estimated cash flows of our purchased credit-impaired (“PCI”) loans, and judgments regarding the valuation of intangible assets and securities as well as the valuation allowance against deferred tax assets are the most critical accounting policies because they are important to the presentation of the Company’s financial condition and results of operations, involve a higher degree of complexity, and require management to make difficult and subjective judgments which often require assumptions or estimates about highly uncertain matters. The use of different judgments, assumptions, and estimates could result in material differences in the results of operations or financial condition. These critical accounting policies and their application are reviewed periodically and, at least annually, with the Audit Committee of the Board of Directors. For a further discussion of the critical accounting policies of the Company, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.

Overview

This overview highlights selected information and may not contain all the information that is important to you in understanding our performance during the period. For a more complete understanding of trends, events, commitments, uncertainties, liquidity, capital resources, and critical accounting estimates, you should read this entire document carefully, as well as our Annual Report on Form 10-K for the year ended December 31, 2016.

Net income was $26.5 million for the nine months ended September 30, 2017, as compared to $17.9 million for the nine months ended September 30, 2016. Basic and diluted earnings per common share were $0.59 and $0.57 for the nine months ended September 30, 2017, respectively, compared to basic and diluted earnings per common share of $0.40 and $0.39 for the nine months ended September 30, 2016, respectively. Earnings for the nine months ended September 30, 2017 reflect the adoption of Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718) (“ASU 2016-09”) which resulted in a $2.3 million, or $0.05 per diluted share, reduction in income tax expense, as well as $1.5 million, or $0.03 per diluted share, of tax-exempt income from bank owned life insurance proceeds in excess of the cash surrender value of the policies. Both of these items were recorded in the first quarter of 2017. Earnings for the nine months ended September 30, 2016, included merger-related expenses associated with the acquisition of Hopewell Valley Community Bank (“Hopewell Valley”) of approximately $2.4 million, net of tax, or $0.05 per diluted share. For the nine months ended September 30, 2017, our return on average assets was 0.91%, as compared to 0.65% for the nine months ended September 30, 2016. For the nine months ended September 30, 2017, our return on average stockholders’ equity was 5.57% as compared to 3.92% for the nine months ended September 30, 2016.

Comparison of Financial Condition at September 30, 2017, and December 31, 2016

Total assets increased $156.7 million, or 4.1%, to $4.01 billion at September 30, 2017, from $3.85 billion at December 31, 2016. The increase was primarily due to an increase in loans held-for-investment, net, of $163.8 million, and an increase in cash and cash equivalents of $7.2 million, partially offset by a decrease in securities available-for-sale of $16.3 million.

Cash and cash equivalents increased $7.2 million, or 7.4%, to $103.2 million at September 30, 2017, from $96.1 million at December 31, 2016. Balances fluctuate based on the timing of receipt of security and loan repayments and the redeployment of cash into other asset classes, or the funding of deposit or borrowing obligations.

The available-for-sale securities portfolio totaled $482.6 million at September 30, 2017, compared to $498.9 million at December 31, 2016, a decrease of $16.3 million, or 3.3%, primarily attributable to paydowns, partially offset by purchases, primarily of corporate bonds. At September 30, 2017, $407.6 million of the portfolio consisted of residential mortgage-backed securities issued or guaranteed by Fannie Mae, Freddie Mac, or Ginnie Mae. In addition, the Company held $73.1 million in corporate bonds, all of which were considered investment grade at September 30, 2017, and other securities of $1.9 million (including $93,000 of equity investments in mutual funds).

As of September 30, 2017, our non-owner occupied commercial real estate concentration (as defined by regulatory guidance issued in 2006) to total risk-based capital was 409%. Management believes that Northfield Bank (the "Bank") has

implemented appropriate risk management practices including risk assessments, board approved underwriting policies and related procedures, which include monitoring bank portfolio performance, performing market analysis (economic and real estate), and stressing of the Bank’s commercial real estate portfolio under severe adverse economic conditions. Although management believes the Bank has implemented appropriate policies and procedures to manage our commercial real estate concentration risk, the Bank’s regulators could require us to implement additional policies and procedures or could require us to maintain higher levels of regulatory capital, which might adversely affect our loan originations, ability to pay dividends, and profitability.

Loans held-for-investment, net, increased $163.8 million, or 5.5%, to $3.13 billion at September 30, 2017, from $2.97 billion at December 31, 2016. The increase was primarily due to originated loan growth. Originated loans held-for-investment, net, totaled $2.36 billion at September 30, 2017, as compared to $2.14 billion at December 31, 2016. The increase was primarily due to an increase in multifamily real estate loans of $183.7 million, or 12.2%, to $1.69 billion at September 30, 2017, from $1.51 billion at December 31, 2016.

For the three months ended September 30, 2017, funded participations totaled $27.2 million.

Acquired loans decreased by $48.2 million to $745.1 million at September 30, 2017, from $793.2 million at December 31, 2016, primarily due to paydowns, partially offset by purchases of one-to-four family residential mortgage and multifamily real estate loan pools totaling $58.7 million in the nine months ended September 30, 2017. The geographic locations of the properties collateralizing the loans are as follows: 63.9% in New York, 10.0% in California, and 26.1% in other states.

PCI loans totaled $26.0 million at September 30, 2017, as compared to $30.5 million at December 31, 2016. The majority of the PCI loan balance consists of loans acquired as part of a Federal Deposit Insurance Corporation-assisted transaction. The Company accreted interest income of $1.4 million and $4.1 million attributable to PCI loans for the three and nine months ended September 30, 2017, respectively, as compared to $1.3 million and $4.0 million for the three and nine months ended September 30, 2016, respectively.

Total liabilities increased $132.9 million, or 4.1%, to $3.36 billion at September 30, 2017, from $3.23 billion at December 31, 2016. The increase was primarily attributable to increases in deposits of $21.8 million, and other borrowings of $114.5 million, partially offset by a decrease in securities sold under agreements to repurchase of $4.0 million.

Deposits increased $21.8 million, or 0.8%, to $2.74 billion at September 30, 2017, as compared to $2.71 billion at December 31, 2016. The increase was attributable to increases of $151.5 million in certificates of deposit accounts and $3.7 million in money market accounts, partially offset by decreases of $67.9 million in transaction accounts and $65.5 million in savings accounts.

Borrowings and securities sold under agreements to repurchase increased by $110.5 million, or 23.3%, to $583.7 million at September 30, 2017, from $473.2 million at December 31, 2016. Management utilizes borrowings to mitigate interest rate risk, for short-term liquidity, and to a lesser extent as part of leverage strategies. The following is a table of term borrowing maturities (excluding capitalized leases and floating rate advances) and the weighted average rate by year at September 30, 2017 (dollars in thousands):

Total stockholders’ equity increased by $23.9 million to $645.0 million at September 30, 2017, from $621.2 million at December 31, 2016. The increase was primarily attributable to net income of $26.5 million for the nine months ended September 30, 2017, and to a lesser extent a $6.5 million increase related to equity award activity, and a $1.9 million reduction in unrealized losses on our securities available-for-sale portfolio. These increases were partially offset by dividend payments of $11.0 million.

Comparison of Operating Results for the Nine Months Ended September 30, 2017 and 2016

Net Income. Net income was $26.5 million and $17.9 million for the nine months ended September 30, 2017, and September 30, 2016, respectively. Significant variances from the comparable prior year period are as follows: a $4.3 million increase in net interest income, a $1.0 million increase in the provision for loan losses, a $1.8 million increase in non-interest income, a $5.4 million decrease in non-interest expense, and a $1.9 million increase in income tax expense.

Interest Income. Interest income increased $5.4 million, or 5.8%, to $98.3 million for the nine months ended September 30, 2017, from $92.9 million for the nine months ended September 30, 2016, due to an increase in the average balance of interest-earning assets of $187.1 million, or 5.5%, and a one basis point increase in the yields earned on interest-earning assets. Interest income on loans increased by $6.3 million, primarily attributable to an increase in the average loan balances of $297.5 million, which was partially offset by a 12 basis point decrease in the yield. The Company accreted interest income related to its PCI loans of $4.1 million for the nine months ended September 30, 2017, as compared to $4.0 million for the nine months ended September 30, 2016. Interest income on loans for the nine months ended September 30, 2017, reflected loan prepayment income of $886,000 compared to $1.4 million for the nine months ended September 30, 2016.

Interest Expense. Interest expense increased $1.1 million, or 6.61%, to $17.3 million for the nine months ended September 30, 2017, as compared to $16.2 million for nine months ended September 30, 2016, primarily due to a $1.0 million increase in interest expense on deposits. The increase in interest expense on deposits was attributed to an increase in the cost of interest-bearing deposits of two basis points to 0.68% for the nine months ended September 30, 2017 as compared to 0.66% for

Table of Contents

the comparable prior year period and an increase in the average balance of interest bearing deposit accounts of $138.7 million, or 6.4%, to $2.31 billion for the nine months ended September 30, 2017, from $2.17 billion for the nine months ended September 30, 2016.

Net Interest Income. Net interest income for the nine months ended September 30, 2017, increased $4.3 million, or 5.6%, to $80.9 million, from $76.6 million for the nine months ended September 30, 2016, primarily due to a $187.1 million, or 5.5%, increase in our average interest-earning assets while net interest margin remained level at 2.99%. The increase in average interest-earning assets was due primarily to an increase in average loans outstanding of $297.5 million, partially offset by decreases in average mortgage-backed securities of $107.4 million and interest-earning deposits in financial institutions of $12.9 million. The increase in average loans was primarily due to originated loan growth. Yields earned on interest-earning assets increased one basis point to 3.63% for the nine months ended September 30, 2017, from 3.62% for the nine months ended September 30, 2016, primarily driven by higher yields on securities, Federal Home Loan Bank of New York stock and interest-earning deposits in financial institutions, partially offset by lower yields on loans. The cost of interest-bearing liabilities increased one basis point to 0.82% for the nine months ended September 30, 2017, from 0.81% for the nine months ended September 30, 2016, primarily due to higher rates on certificates of deposits.

Provision for Loan Losses. The provision for loan losses increased by $1.0 million to $1.4 million for the nine months ended September 30, 2017, from $355,000 for the nine months ended September 30, 2016, primarily due to growth in the loan portfolio, partially offset by declines in non-performing loans and net recoveries during the nine months ended September 30, 2017. Net recoveries for the nine months ended September 30, 2017, were $133,000, primarily relating to insurance proceeds received from a previously charged-off loan, as compared to net charge-offs of $785,000 for the comparative prior year period.

Non-interest Income. Non-interest income increased $1.8 million, or 23.8%, to $9.2 million for the nine months ended September 30, 2017, from $7.4 million for the nine months ended September 30, 2016, primarily due to an increase of $1.4 million in income on bank owned life insurance, attributable to insurance proceeds in excess of the related cash surrender value of the policies, and an increase of $389,000 in gains on securities transactions, net. Securities gains, net, during the nine months ended September 30, 2017, included gains of $1.0 million related to the Company’s trading portfolio, compared to gains of $389,000 in the comparative prior year period. The trading portfolio is utilized to fund the Company’s deferred compensation obligation to certain employees and directors of the Company's deferred compensation plan (the "Plan"). The participants of this Plan, at their election, defer a portion of their compensation. Gains and losses on trading securities have no effect on net income since participants benefit from, and bear the full risk of, changes in the trading securities market values. Therefore, the Company records an equal and offsetting amount in compensation expense, reflecting the change in the Company’s obligations under the Plan.

Non-interest Expense. Non-interest expense decreased $5.4 million, or 9.5%, to $51.0 million for the nine months ended September 30, 2017, from $56.4 million for the nine months ended September 30, 2016. The decrease was primarily due to a $3.9 million reduction in merger-related expenses associated with the Hopewell Valley acquisition reflected in the first nine months of 2016. Compensation and employee benefits expense decreased $1.6 million, due primarily to a reduction in severance, retention, and change-in-control compensation associated with the Hopewell Valley acquisition in the prior year period, partially offset by annual merit-related salary increases and an increase in expenses related to the Company’s deferred compensation plan, which is described above, and which has no effect on net income. Data processing fees decreased $1.5 million, primarily due to non-recurring conversion costs and contract termination costs associated with the Hopewell Valley acquisition incurred in the prior year period. Professional fees decreased $587,000 due to non-recurring merger-related professional fees associated with the Hopewell Valley acquisition. FDIC insurance expense decreased by $423,000 due to a reduction in the FDIC's assessment rates for depository institutions with less than $10.0 billion in assets, which became effective in the quarter ended September 30, 2016. Other expense decreased by $1.0 million, primarily due to lower directors' equity award expense, related to the retirement of three directors.

Income Tax Expense. The Company recorded income tax expense of $11.3 million for the nine months ended September 30, 2017, compared to $9.4 million for the nine months ended September 30, 2016. The effective tax rate for the nine months ended September 30, 2017, was 29.9% compared to 34.4% for the nine months ended September 30, 2016. As previously disclosed, the Company adopted ASU 2016-09 in the first quarter of 2017, which resulted in a $2.3 million reduction in income tax expense related to the exercise or vesting of equity awards during the nine months ended September 30, 2017. Previously, these tax benefits were recorded through equity as an adjustment to additional paid in capital. The effective tax rate for the nine months ended September 30, 2017, also was affected by $1.5 million of tax-exempt income from bank owned life insurance proceeds in excess of the cash surrender value of the policies. In accordance with applicable accounting standards, the tax effect will be recognized evenly throughout the year.

Comparison of Operating Results for the Three Months Ended September 30, 2017 and 2016

Net Income. Net income was $8.1 million and $7.3 million for the quarters ended September 30, 2017, and September 30, 2016, respectively. Significant variances from the comparable prior year quarter are as follows: a $1.1 million increase in net interest income, a $16,000 increase in the provision for loan losses, a $52,000 decrease in non-interest income, a $549,000 decrease in non-interest expense, and a $743,000 increase in income tax expense.

Interest Income. Interest income increased $2.0 million, or 6.3%, to $33.5 million for the quarter ended September 30, 2017, from $31.5 million for the quarter September 30, 2016, due to an increase in the average balance of interest-earning assets of $151.1 million, or 4.3%, and a six basis point increase in the yields earned on interest-earning assets. Interest income on loans increased by $2.2 million, primarily attributable to an increase in the average loan balances of $254.8 million, partially offset by a five basis point decrease in the yield. The increase in average loans was primarily due to originated loan growth. The Company accreted interest income related to its PCI loans of $1.4 million for the quarter ended September 30, 2017, as compared to $1.3 million for the quarter ended September 30, 2016. Interest income on loans for the quarter ended September 30, 2017, reflected loan prepayment income of $366,000 compared to $459,000 for the quarter ended September 30, 2016.

Interest Expense. Interest expense increased $899,000, or 17.0%, to $6.2 million for the quarter ended September 30, 2017, from $5.3 million for the quarter ended September 30, 2016. The increase was due to an increase of $623,000 in interest expense on deposits and a $276,000 increase in interest expense on borrowings. The increase in interest expense on deposits was attributed to an increase in the average balance of interest-bearing deposits of $101.9 million, or 4.6%, to $2.34 billion for the quarter ended September 30, 2017, from $2.24 billion for the quarter ended September 30, 2016, and an eight basis point increase in the cost of interest-bearing deposits. Interest expense on borrowings increased by $276,000 due to a $36.8 million, or 7.9%, increase in the average balances of borrowings to $503.2 million for the quarter ended September 30, 2017, from $466.5 million for the quarter ended September 30, 2016 and an 11 basis point increase in the cost of borrowings.

Net Interest Income. Net interest income for the quarter ended September 30, 2017, increased $1.1 million, or 4.2%, primarily due to a $151.1 million, or 4.3%, increase in our average interest-earning assets, partially offset by a one basis point decrease in our net interest margin to 2.97%. The increase in average interest-earning assets was primarily attributable to an increase in average loans outstanding of $254.8 million, partially offset by decreases in average mortgage-backed securities of $111.9 million. Yields earned on interest-earning assets increased six basis points to 3.64% for the quarter ended September 30, 2017, from 3.58% for the quarter ended September 30, 2016, primarily driven by higher yields on securities, Federal Home Loan Bank of New York stock, and interest-earning deposits in financial institutions, partially offset by lower yields on loans. The cost of interest-bearing liabilities increased eight basis points to 0.86% for the current quarter as compared to 0.78% for the comparable prior year quarter due to higher rates across all interest-bearing deposits and borrowed funds.

Provision for Loan Losses. The provision for loan losses increased by $16,000 to $488,000 for the quarter ended September 30, 2017, from $472,000 for the quarter ended September 30, 2016, primarily due to growth in the loan portfolio, partially offset by declines in non-performing loans and net recoveries during the current quarter. Net recoveries were $6,000 for the quarter ended September 30, 2017, compared to net charge-offs of $449,000 for the quarter ended September 30, 2016.

Non-interest Income. Non-interest income remained relatively stable at $2.6 million for the quarter ended September 30, 2017, as compared to $2.7 million for the quarter ended September 30, 2016.

Non-interest Expense. Non-interest expense decreased $549,000, or 3.2%, to $16.8 million for the quarter ended September 30, 2017, from $17.4 million for the quarter ended September 30, 2016. The decrease was due primarily to a decrease of $519,000 in data processing fees, related to a contract termination fee associated with the Hopewell Valley acquisition, incurred in the comparable prior year quarter.

Income Tax Expense. The Company recorded income tax expense of $4.5 million for the quarter ended September 30, 2017, compared to $3.8 million for the quarter ended September 30, 2016.

Asset Quality

Purchased Credit Impaired Loans

PCI loans are recorded at estimated fair value using discounted expected future cash flows deemed to be collectible on the date acquired. Based on its detailed review of PCI loans and experience in loan workouts, management believes it has a reasonable expectation about the amount and timing of future cash flows and accordingly has classified PCI loans ($26.0 million at September 30, 2017 and $30.5 million at December 31, 2016) as accruing, even though they may be contractually past due. At September 30, 2017, 8.6% of PCI loans were past due 30 to 89 days, and 18.2% were past due 90 days or more, as compared to 6.6% and 19.3%, respectively, at December 31, 2016.

At September 30, 2017, the $254,000 non-accruing TDR was not performing in accordance with its restructured terms and consisted of one one-to-four family residential loan which was over 90 days delinquent at September 30, 2017, and collateralized by real estate with a recent appraised value of $629,000. At December 31, 2016, $1.4 million, or 76.4%, of the $1.8 million TDRs were not performing in accordance with their restructured terms.

The Company also holds loans subject to restructuring agreements that are on accrual status totaling $20.2 million and $20.6 million at September 30, 2017, and December 31, 2016, respectively. At September 30, 2017, $1.3 million, or 6.4%, of the $20.2 million accruing TDRs were not performing in accordance with their restructured terms. The $1.3 million is comprised of two loans, both of which were 30 - 89 days delinquent at September 30, 2017, and collateralized by real estate with an aggregate recent appraised value of $1.6 million.

Liquidity and Capital Resources

Liquidity. The overall objective of our liquidity management is to ensure the availability of sufficient funds to meet financial commitments and to take advantage of lending and investment opportunities. The Bank manages liquidity in order to meet deposit withdrawals on demand or at contractual maturity, to repay borrowings as they mature, and to fund new loans and investments as opportunities arise.

The Bank's primary sources of funds are deposits, principal and interest payments on loans and securities, borrowed funds, the proceeds from maturing securities and short-term investments, and to a lesser extent, the proceeds from the sales of loans and securities and wholesale borrowings. The scheduled amortization of loans and securities, as well as proceeds from borrowed funds, are predictable sources of funds. Other funding sources, however, such as deposit inflows and loan prepayments are greatly influenced by market interest rates, economic conditions, and competition. The Bank is a member of the Federal Home Loan Bank of New York (the “FHLB”), which provides an additional source of short-term and long-term funding. The Bank also has short-term borrowing capabilities with the Federal Reserve Bank of New York. The Bank’s borrowed funds, excluding capitalized lease obligations and floating rate advances, were $573.2 million at September 30, 2017, and had a weighted average interest rate of 1.57%. A total of $237.6 million of these borrowings will mature in less than one year. Borrowed funds, excluding capitalized lease obligations and floating rate advances, were $462.0 million at December 31, 2016. The Bank has the ability to obtain additional funding from the FHLB and Federal Reserve Bank of New York's discount window of approximately $861.1 million utilizing unencumbered securities of $64.3 million and loans of $883.0 million at September 30, 2017. The Bank expects to have sufficient funds available to meet current commitments in the normal course of business.

Northfield Bancorp, Inc. (standalone) is a separate legal entity from the Bank and must provide for its own liquidity to pay dividends, repurchase its stock, and for other corporate purposes. Northfield Bancorp, Inc.'s primary source of liquidity is dividend payments from the Bank. At September 30, 2017, Northfield Bancorp, Inc. (standalone) had liquid assets of $24.9 million.

During the first quarter of 2017, the Company enhanced its liquidity position by arranging for a municipal line of credit from the FHLB to be used, if needed, to collateralize our municipal deposits.

Capital Resources. Federal regulations require federally insured depository institutions to meet several minimum capital standards: a common equity Tier 1 capital to risk-based assets ratio of 4.5%, a Tier 1 capital to risk-based assets ratio of 6.0%, a total capital to risk-based assets of 8.0%, and a 4.0% Tier 1 capital to total assets leverage ratio. These capital requirements were effective January 1, 2015, and are the result of a final rule implementing recommendations of the Basel Committee on Banking Supervision and certain requirements of the Dodd-Frank Act. In addition to establishing the minimum regulatory capital requirements, the regulations limit capital distributions and certain discretionary bonus payments to management if the institution does not hold a “capital conservation buffer” consisting of 2.5% of capital to risk-weighted assets above the amount necessary to meet its minimum risk-based capital requirements. The capital conservation buffer requirement was phased in beginning January 1, 2016, at 0.625% of risk-weighted assets and increases each year until fully implemented at 2.5% on January 1, 2019.

Off-Balance Sheet Arrangements and Contractual Obligations

In the normal course of operations, the Company engages in a variety of financial transactions that, in accordance with U.S. GAAP, are not recorded in the financial statements. These transactions primarily relate to lending commitments. These arrangements are not expected to have a material impact on the Company's results of operations or financial condition.

The following table shows the contractual obligations of the Company by expected payment period as of September 30, 2017 (in thousands):



Contractual Obligation	Total		Less than One Year		One to less than Three Years		Three to less than Five Years		More than Five Years
Debt obligations (excluding capitalized leases)	$	573,217	$	237,635	$	220,582	$	115,000	$	—
Commitments to originate loans	78,566		78,566		—		—		—
Commitments to fund unused lines of credit	94,035		94,035		—		—		—

Commitments to fund unused lines of credit are agreements to lend additional funds to customers as long as there have been no violations of any of the conditions established in the agreements (original or restructured). Commitments to originate loans generally have a fixed expiration or other termination clauses, which may or may not require payment of a fee. Since some of these loan commitments are expected to expire without being drawn upon, total commitments do not necessarily represent future cash requirements.

For further information regarding our off-balance sheet arrangements and contractual obligations, see "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Management of Market Risk

General. A majority of our assets and liabilities are monetary in nature. Consequently, our most significant form of market risk is interest rate risk. Our assets, consisting primarily of mortgage-related assets and loans, generally have longer maturities than our liabilities, which consist primarily of deposits and wholesale borrowings. As a result, a principal part of our business strategy involves managing interest rate risk and limiting the exposure of our net interest income to changes in market interest rates. Accordingly, our board of directors has established a management risk committee, comprised of our Chief Investment Officer, who chairs this Committee, our President and Chief Executive Officer, our Chief Operating Officer, our Chief Financial Officer, our Chief Lending Officer, our Executive Vice President of Operations and our Executive Vice President of Branch Administration and Business Development. This committee is responsible for, among other things, evaluating the interest rate risk inherent in our assets and liabilities, for recommending to the risk management committee of our board of directors the level of risk that is appropriate given our business strategy, operating environment, capital, liquidity and performance objectives, and for managing this risk consistent with the guidelines approved by the board of directors.

We seek to manage our interest rate risk in order to minimize the exposure of our earnings and capital to changes in interest rates. As part of our ongoing asset-liability management, we currently use the following strategies to manage our interest rate risk:


•	originating multifamily loans and commercial real estate loans that generally tend to have shorter maturities than one-to-four family residential real estate loans and have higher interest rates that generally reset in five to ten years;


•	investing in shorter term (generally less than 10 years) investment grade corporate securities and mortgage-backed securities; and


•	obtaining general financing through lower-cost core deposits, longer-term FHLB advances and repurchase agreements, and brokered deposits.

Shortening the average term of our interest-earning assets by increasing our investments in shorter-term assets, as well as originating loans with variable interest rates, helps to match the maturities and interest rates of our assets and liabilities better, thereby reducing the exposure of our net interest income to changes in market interest rates.

Net Portfolio Value Analysis. We compute amounts by which the net present value of our assets and liabilities (net portfolio value or NPV) would change in the event market interest rates changed over an assumed range of rates. Our simulation model uses a discounted cash flow analysis to measure the interest rate sensitivity of NPV. Depending on current market interest rates, we estimate the economic value of these assets and liabilities under the assumption that interest rates experience an instantaneous and sustained increase of 100, 200, 300, or 400 basis points, or a decrease of 100 and 200 basis points, which is based on the current interest rate environment. A basis point equals one-hundredth of one percent, and 100 basis points equals one percent. An increase in interest rates from 3% to 4% would mean, for example, a 100 basis point increase in the “Change in Interest Rates” column below.

Net Interest Income Analysis. In addition to NPV calculations, we analyze our sensitivity to changes in interest rates through our net interest income model. Net interest income is the difference between the interest income we earn on our interest-earning assets, such as loans and securities, and the interest we pay on our interest-bearing liabilities, such as deposits and borrowings. In our model, we estimate what our net interest income would be for a twelve-month period. Depending on current market interest rates we then calculate what the net interest income would be for the same period under the assumption that interest rates experience an instantaneous and sustained increase or decrease of 100, 200, 300, or 400 basis points, or a decrease of 100 and 200 basis points, which is based on the current interest rate environment.

The following tables set forth, as of September 30, 2017, and December 31, 2016, our calculation of the estimated changes in our NPV, NPV ratio, and percent change in net interest income that would result from the designated instantaneous and sustained changes in interest rates (dollars in thousands). Computations of prospective effects of hypothetical interest rate changes are based on numerous assumptions, including relative levels of market interest rates, loan prepayments and deposit repricing characteristics including decay rates, and correlations to movements in interest rates, and should not be relied on as indicative of actual results.

At September 30, 2017, in the event of a 200 basis point decrease in interest rates, we would experience a 10.77% increase in estimated net portfolio value and a 0.98% increase in net interest income. In the event of a 400 basis point increase in interest rates, we would experience a 21.81% decrease in estimated net portfolio value and a 12.71% decrease in net interest income. Our policies provide that, in the event of a 200 basis point decrease or less in interest rates, our net present value ratio should decrease by no more than 300 basis points and 10%, and in the event of a 400 basis point increase or less, our net present value should decrease by no more than 475 basis points and 35%. In the event of a 200 basis point decrease or less, our projected net interest income should decrease by no more than 10% in year one, and in the event of a 400 basis point increase or less, our projected net interest income should decrease by no more than 30% in year one. However, when the federal funds rate is low and negative rate shocks do not produce meaningful results, management may temporarily suspend use of guidelines for negative interest rate shocks. At September 30, 2017, we were in compliance with all board approved policies with respect to interest rate risk management.

Certain shortcomings are inherent in the methodologies used in determining interest rate risk through changes in net portfolio value and net interest income. Our model requires us to make certain assumptions that may or may not reflect the manner in which actual yields and costs respond to changes in market interest rates. However, we also apply consistent parallel yield curve shifts (in both directions) to determine possible changes in net interest income if the theoretical yield curve shifts occurred gradually. Net interest income analysis also adjusts the asset and liability repricing analysis based on changes in prepayment rates resulting from the parallel yield curve shifts. In addition, the net portfolio value and net interest income information presented assume that the composition of our interest-sensitive assets and liabilities existing at the beginning of a period remains constant over the period being measured and assume that a particular change in interest rates is reflected uniformly across the yield curve regardless of the duration or repricing of specific assets and liabilities. Accordingly, although interest rate risk calculations provide an indication of our interest rate risk exposure at a particular point in time, such measurements are not intended to and do not provide a precise forecast of the effect of changes in market interest rates on our net portfolio value or net interest income and will differ from actual results.
