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 six months ended June 30, 2018 , are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2018 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, 2017 , of the Company as filed with the SEC.

The Company held 33 pass-through mortgage-backed securities issued or guaranteed by GSEs, 19 REMIC mortgage-backed securities issued or guaranteed by GSEs, one REMIC mortgage-backed security not issued or guaranteed by a GSE, and three corporate bonds that were in a continuous unrealized loss position of twelve months or greater at June 30, 2018 . There were 40 pass-through mortgage-backed securities issued or guaranteed by GSEs, 37 REMIC mortgage-backed securities issued or guaranteed by a GSE, and 13 corporate bonds that were in an unrealized loss position of less than twelve months at June 30, 2018 . All securities referred to above were rated investment grade at June 30, 2018 . The declines in value relate to the general interest rate environment and are considered temporary. The securities cannot be prepaid in a manner that would result in the Company not receiving substantially all of its amortized cost. The Company neither has an intent to sell, nor is it more likely than not that the Company will be required to sell, the securities before the recovery of their amortized cost basis or, if necessary, maturity.

The fair values of our investment securities could decline in the future if the underlying performance of the collateral for the collateralized mortgage obligations or other securities deteriorates and our credit enhancement levels do not provide sufficient protections to our contractual principal and interest, which may result in other-than-temporary impairment in the future. The Company did no t recognize any other-than-temporary impairment charges during the three and six months ended June 30, 2018 , or June 30, 2017 .

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 six months ended June 30, 2018 , or June 30, 2017 .

At June 30, 2018 , debt securities held-to-maturity with a carrying value of $7.1 million were pledged to secure borrowings and deposits.

Notes to Unaudited Consolidated Financial Statements - (Continued)

The Company held two pass-through mortgage-backed securities held-to-maturity, issued or guaranteed by GSEs that were in a continuous unrealized loss position of greater than twelve months at June 30, 2018 , and four pass-through mortgage-backed securities held-to-maturity, issued or guaranteed by GSEs that were in a continuous unrealized loss position of less than twelve months at June 30, 2018 . 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. The Company did no t recognize any other-than-temporary impairment charges in earnings on securities held-to-maturity during the three and six months ended June 30, 2018 , or June 30, 2017 .

Note 4 – Equity Securities

At both June 30, 2018 , and December 31, 2017, equity securities totaled $1.3 million . Equity securities consist of money market mutual funds, recorded at fair value of $272,000 and $323,000 , at June 30, 2018 , and December 31, 2017 , respectively, and an investment in a private Small Business Administration (“SBA”) Loan Fund recorded at net asset value of $1.0 million at both June 30, 2018 , and December 31, 2017 . As the SBA Loan Fund operates as a private fund, its shares are not publicly traded and therefore have no readily determinable market value. The investment in the fund is recorded at net asset value as a practical expedient for reporting fair market value. Upon adoption of Accounting Standards Update (“ASU”) No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities as of January 1, 2018, the Company reclassified its equity securities out of available-for-sale securities to equity securities on the consolidated balance sheets for all periods presented. For further details on ASU No. 2016-01 see Note 12 - “Recently Issued and Adopted Accounting Pronouncements.”

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.

Included in loans receivable (including loans held-for-sale) are loans for which the accrual of interest income has been discontinued due to deterioration in the financial condition of the borrowers. The recorded investment of these non-accrual loans was $6.4 million and $5.5 million at June 30, 2018 , and December 31, 2017 , 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 $3.3 million and $3.1 million at June 30, 2018 , and December 31, 2017 , respectively. Loans on non-accrual status with principal balances less than $500,000 , and therefore not meeting the Company’s definition of an impaired loan, amounted to $3.1 million and $2.4 million at June 30, 2018 , and December 31, 2017 , respectively. There were no non-accrual loans held-for-sale at June 30, 2018 and December 31, 2017 . There were no loans past due 90 days or more and still accruing interest at June 30, 2018 . Loans past due 90 days or more and still accruing interest were $28,000 at December 31, 2017 , and consisted of loans that are considered well-secured and in the process of collection.

There were no loans modified as troubled debt restructurings (TDRs) during the three and six months ended June 30, 2018 and 2017.

At June 30, 2018 , and December 31, 2017 , we had TDRs of $17.3 million and $18.3 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 June 30, 2018 , there were no TDR loans that were restructured during the preceding twelve months ended June 30, 2018 , that subsequently defaulted.

Note 8 – Fair Value Measurements

The following tables present the assets reported on the consolidated balance sheets at their estimated fair value as of June 30, 2018 , and December 31, 2017 , 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.

The methods of determining the fair value of assets and liabilities presented in this note are consistent with our methodologies disclosed in Note 14 to the Consolidated Financial Statements of the Company’s 2017 Annual Report on Form 10-K, except for the valuation of loans held for investment which was impacted by the adoption of ASU No. 2016-01. In accordance with ASU No. 2016-01, the fair value of loans held for investment is estimated using an “exit price” approach in estimating and disclosing fair value of financial instruments incorporating discounts for credit, liquidity and marketability factors. The fair values shown as of December 31, 2017, use an “entry price” approach. For further details on ASU 2016-01 see Note 12 - “ Recently Issued and Adopted Accounting Pronouncements. ”

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 June 30, 2018, and December 31, 2017.

Debt Securities Available for Sale: The estimated fair values for mortgage-backed securities, corporate, and other debt 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. There were no transfers of securities between Level 1 and Level 2 during the six months ended June 30, 2018 .

Trading Securities: Fair values are derived from quoted market prices in active markets. The assets consist of publicly traded mutual funds.

Equity Securities: Fair values of equity securities consisting of publicly traded mutual funds are derived from quoted market prices in active markets.

Impaired Loans: At June 30, 2018 , and December 31, 2017 , the Company had impaired loans held-for-investment (excluding PCI loans) with outstanding principal balances of $9.2 million and $8.8 million , respectively, which were recorded at their estimated fair value of $6.8 million and $6.5 million , respectively. The Company recorded a net decrease in the specific reserve for impaired loans of $39,000 and $127,000 for the six months ended June 30, 2018 and June 30, 2017 , respectively, utilizing level 3 inputs. For purposes of estimating the fair value of impaired loans, management utilizes independent appraisals, if the loan is collateral dependent, adjusted downward by management, as necessary, for changes in relevant valuation factors subsequent to the appraisal date, or the present value of expected future cash flows for non-collateral dependent loans and troubled debt restructurings.

Other Real Estate Owned (OREO): At both June 30, 2018 , and December 31, 2017, 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.

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)	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.


(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.

The estimated fair value of the Company’s financial instruments at June 30, 2018 , and December 31, 2017 , is presented in the following tables (in thousands):

Limitations

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected losses, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Fair value estimates are based on existing on-and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

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. 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.

The following is a summary of the Company’s earnings per share calculations and reconciliation of basic to diluted earnings per share for the periods indicated (dollars in thousands, except per share data):



	Three Months Ended June 30,				Six Months Ended June 30,

Note 10 – 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, 2017. During the quarter ended March 31, 2018, the Company entered into a new lease agreement for 1,800 square feet of space at a branch facility in Brooklyn, New York, for a minimum term of 15 years through March 31, 2033 , with three five -year options to renew. Pursuant to the terms of this lease we estimate our total additional future minimum rent payments to be approximately $5.8 million .

Note 11 – Revenue Recognition

Effective January 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers ( “ Topic 606 ”) and all subsequent ASUs that modified Topic 606. For further details on ASU No. 2014-09 see Note 12 - “ Recently Issued and Adopted Accounting Pronouncements. ” The adoption of ASU No. 2014-09 did not have a material impact on the measurement or recognition of revenue as it does not apply to revenue associated with financial instruments, including revenue from loans and investment securities, which is the Company's primary source of revenue. In addition, certain non-interest income streams such as income on bank owned life insurance, gains on securities transactions, and other non-interest income are not in the scope of the guidance. The Company’s revenue streams that are within the scope of Topic 606 include service charges on deposit accounts, ATM and card interchange fees, and investment services fees. However, the revenue recognition of these revenue streams did not change upon adoption of Topic 606 as our customer contracts generally do not have performance obligations and fees are assessed and collected as the transaction occurs.

The following table summarizes non-interest income for the periods indicated (in thousands):



	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2018		2017		2018		2017
Fees and service charges for customer services:
Service charges	$	771	768		$	1,612	1,640
ATM and card interchange fees	313		284		580		544
Investment fees	63		55		169		141
Total fees and service charges for customer services	1,147		1,107		2,361		2,325
Income on bank owned life insurance	914		1,010		1,868		3,468
Gains on securities transactions, net	313		256		473		664
Other	71		64		147		127
Total non-interest income	$	2,445	$	2,437	$	4,849	$	6,584

The following revenue streams are within the scope of Topic 606:

Fees and service charges for customer services. Fees and service charges for customer services include: (i) service charges on deposit accounts, including account maintenance fees, overdraft fees, insufficient funds fees, wire fees, and other deposit related fees; (ii) ATM and card interchange fees, which include fees generated when a Bank cardholder uses a non-Bank ATM or a non-Bank cardholder uses a Bank ATM, and fees earned whenever the Bank's debit cards are processed through card payment networks such as Visa; and (iii) investment services fees earned through partnering with a third party investment and brokerage service firm to provide insurance and investment products to customers. The Company's performance obligation for fees and service charges is satisfied and related revenue recognized immediately or in the month of performance of services.

Note 12 – Recently Issued and Adopted Accounting Pronouncements

Accounting Pronouncements Adopted in 2018

ASU No. 2014-09. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) . The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies generally will be required to use more judgment and make more estimates than under current guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. Subsequent to the issuance of ASU No. 2014-09, the FASB issued targeted updates to clarify specific implementation issues including ASU No. 2016-08, “Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” ASU No. 2016-10, “Identifying Performance Obligations and Licensing,” ASU No. 2016-12, “Narrow-Scope Improvements and Practical Expedients,” and ASU No. 2016-20 “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers.” The new standard was effective for the Company on January 1, 2018. The adoption of ASU No. 2014-09 did not have a material impact on the Company’s consolidated financial statements and related disclosures as the Company’s primary sources of revenues are derived from interest income on financial assets that are not within the scope of the guidance. Management conducted an assessment of the revenue streams that were potentially affected by the guidance and reviewed contracts in scope to ensure compliance with the guidance. These contracts included those related to service charges on deposit accounts, ATM and card interchange fees, and investment services fees. The Company’s revenue recognition pattern for these revenue streams did not change from current practice. Additional disclosures required by the standard have been included in Note 11. “Revenue Recognition.”

ASU No. 2016-01. 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 including the following: 1) Requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; 2) Simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; 3) Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; 4) Requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value and 5) Reduces diversity in current practice by clarifying that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity’s other deferred tax assets. ASU No. 2016-01 is effective for the Company for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The Company adopted ASU No. 2016-01 effective January 1, 2018, which did not have a material impact on the Company’s consolidated financial statements due to the Company's proportionately small portfolio of equity securities and no liabilities that are measured at fair value. The primary impact of the adoption of ASU No. 2016-01 was the reclassification of equity securities from available-for-sale to equity securities on the consolidated balance sheets and the use of an exit price notion for valuing loans at fair value. See Note 4 - “Equity Securities” and Note 8 - “Fair Value Measurements” for further details.

ASU No. 2016-15. 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 how certain cash receipts and cash payments should be classified and presented in the statement of cash flows. ASU No. 2016-15 includes guidance on eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU No. 2016-15 is effective for annual and interim reporting periods beginning after December 15, 2017. The Company adopted ASU No. 2016-15 effective January 1, 2018, which did not have a material impact on the Company's consolidated statements of cash flows.

Notes to Unaudited Consolidated Financial Statements - (Continued)

ASU No. 2017-07. In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , which requires that companies disaggregate the service cost component from other components of net benefit cost. The guidance requires companies that offer postretirement benefits to present the service cost, which is the amount an employer has to set aside each quarter or fiscal year to cover the benefits, in the same line item with other current employee compensation costs. Other components of net benefit cost will be presented in the income statement separately from the service cost component and outside the subtotal of income from operations, if one is presented. The Company adopted ASU No. 2017-07 effective January 1, 2018, which did not have a material impact on the Company’s consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

ASU 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. ASU 2018-07 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company's share-based payment awards to nonemployees consist only of grants made to the Company's Directors as compensation solely related to the individual's role as a Director. As such, the ASU is not expected to 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.

ASU No. 2018-03. In February 2018, the FASB issued ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments-Overall (Subtopic 825-10), which clarifies certain aspects of the guidance issued in ASU No. 2016-01 including: the ability to irrevocably elect to change the measurement approach for equity securities measured using the practical expedient (at cost plus or minus observable transactions less impairment) to a fair value method in accordance with Topic 820, Fair Value Measurement; clarification that if an observable transaction occurs for such securities, the adjustment is as of the observable transaction date; clarification that the prospective transition approach for equity securities without a readily determinable fair value is meant only for instances in which the practical expedient is elected; and various other clarifications. ASU No. 2018-03 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. Adoption is not expected to have a material impact on the Company's consolidated financial statements.

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. ASU No. 2017-08 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted, and is to be applied using the modified retrospective method. ASU No. 2017-08 is not expected to have a significant effect 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

Table of Contents

NORTHFIELD BANCORP, INC.

Notes to Unaudited Consolidated Financial Statements - (Continued)

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 also established a CECL working group that includes individuals from various functional areas to assess processes and has selected a third-party vendor to assist in the application of the ASU No. 2016-13. 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. 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.

ASU No. 2016-02. 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. The Company has several lease agreements, such as branch locations, which are currently considered operating leases, and therefore, not recognized on the Company’s consolidated statements of condition. The guidance will require these lease agreements to be recognized on the consolidated balance sheets as a right-of-use asset and a corresponding lease liability. Therefore, the Company’s preliminary evaluation indicates the provisions of ASU No. 2016-02 are expected to impact the Company’s consolidated balance sheets; the extent of such impact is under evaluation. The Company does not expect the guidance to have a material impact on its results of operations. The Company is nearing completion of identifying a complete inventory of arrangements containing a lease and accumulating the data necessary to apply the amended guidance. The Company has contracted with a third-party software vendor to aid in the transition to the new leasing guidance implementation.

•	general economic conditions, either nationally or in our market areas, including employment prospects, real estate values and conditions, that are worse than expected;


•	competition among depository and other financial institutions;


•	inflation and changes in the interest rate environment that reduce our margins and yields or reduce the fair value of financial instruments;


•	adverse changes in the securities, credit markets or real estate values;


•	changes in laws, tax policies, or government regulations or policies affecting financial institutions, including changes in regulatory fees and capital requirements;


•	our ability to manage operations in the current economic conditions;

•	the ability of third-party providers to perform their obligations to us;


•	the ability of the U.S. Government to manage federal debt limits;


•	significant increases in our loan losses, including increases that may result from the new authoritative accounting guidance known as the current expected credit loss (“CECL”) model which may increase the required level of our allowance for loan losses after adoption effective January 1, 2020;


•	changes in our income tax expense resulting from the impact of recently enacted state and federal corporate tax reform; and


•	changes in the financial condition, results of operations, or future prospects of issuers of securities that we own.

Because of these and other uncertainties, our actual future results may be materially different from the results indicated by these forward-looking statements. Accordingly, you should not place undue reliance on such statements.

Except as required by law, we disclaim any intention or obligation to update or revise any forward-looking statements after the date of this Quarterly Report on Form 10-Q, whether as a result of new information, future events or otherwise.

Critical Accounting Policies

Note 1 to the Company’s Audited Consolidated Financial Statements for the year ended December 31, 2017 , 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, 2017 .

Net income was $21.1 million for the six months ended June 30, 2018 , as compared to $18.4 million for the six months ended June 30, 2017 . Basic and diluted earnings per common share were $0.46 and $0.45 , respectively, for the six months ended June 30, 2018 , compared to basic and diluted earnings per common share of $0.41 and $0.39 , respectively, for the six months ended June 30, 2017 . Earnings for the six months ended June 30, 2018 benefited from a lower effective tax rate due to the enactment of the Tax Cuts and Jobs Act in the fourth quarter of 2017 (the “Tax Reform Act”), which reduced the federal statutory corporate tax rate to 21% from 35%. Earnings for the six months ended June 30, 2018, also benefited from excess tax benefits of $2.1 million, or $0.05 per diluted share, related to the exercise or vesting of equity awards. Earnings for the six months ended June 30, 2017, benefited from excess tax benefits of $2.3 million, or $0.05 per diluted share, related to the exercise or vesting of equity awards, 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. For the six months ended June 30, 2018 , our return on average assets was 1.04% , as compared to 0.95% for the six months ended June 30, 2017 . For the six months ended June 30, 2018 , our return on average stockholders’ equity was 6.59% as compared to 5.86% for the six months ended June 30, 2017 .

On July 1, 2018, the State of New Jersey enacted new legislation that created a temporary surtax effective for tax years 2018 through 2021 and will require certain companies to file combined tax returns beginning in 2019. Management is currently evaluating the effect of this new legislation on our net deferred tax asset and future tax expense. We anticipate that we will realize a tax benefit during the third quarter of 2018 due to the write up of our net deferred tax asset and, prospectively, our state tax expense will increase.

Comparison of Financial Condition at June 30, 2018 , and December 31, 2017

Total assets increase d $196.7 million , or 4.9% , to $4.19 billion at June 30, 2018 , from $3.99 billion at December 31, 2017 . The increase was primarily due to an increase in our available-for sale debt securities portfolio of $111.5 million and an increase in loans held-for-investment, net, of $79.3 million .

The Company’s debt securities available-for-sale portfolio increased by $111.5 million , or 21.7% , to $625.3 million at June 30, 2018 , from $513.8 million at December 31, 2017 . The increase was primarily attributable to purchases of mortgage-

backed and corporate securities, partially offset by paydowns and sales. At June 30, 2018 , $272.7 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 $109.1 million in corporate bonds, all of which were considered investment grade at June 30, 2018 , and $279,000 in municipal bonds. The effective duration of the securities portfolio at June 30, 2018 was 3.36 years.

As of June 30, 2018 , our commercial real estate concentration (as defined by regulatory guidance issued in 2006) to total risk-based capital was 411%. 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, increase d $79.3 million to $3.22 billion at June 30, 2018 , from $3.14 billion at December 31, 2017 . Originated loans held-for-investment, net, totaled $2.55 billion at June 30, 2018 , as compared to $2.43 billion at December 31, 2017 . The increase was primarily due to an increase in multifamily real estate loans of $64.7 million , or 3.7% , to $1.80 billion at June 30, 2018 , from $1.74 billion at December 31, 2017 , and an increase in commercial real estate loans of $54.3 million , or 12.2% , to $499.5 million at June 30, 2018 , from $445.2 million at December 31, 2017 , partially offset by decreases in acquired loans and purchased credit-impaired ( “ PCI ” ) loans.

The geographic locations of the properties collateralizing the loans purchased are as follows: 32.7% in New York, 29.9% in California, and 27.1% in Massachusetts, with the majority of the remaining balance in New Jersey. There were no loan pool purchases during the six months ended June 30, 2017.

PCI loans totaled $21.3 million at June 30, 2018 , as compared to $22.7 million at December 31, 2017 . The majority of the PCI loan balance consists of loans acquired as part of a Federal Deposit Insurance Corporation-assisted transaction.

Total liabilities increase d $186.0 million , or 5.5% , to $3.54 billion at June 30, 2018 , from $3.35 billion at December 31, 2017 . The increase was primarily attributable to an increase in deposits of $130.3 million , an increase in other borrowings of $54.8 million , and an increase in advance payments by borrowers for taxes and insurance of $3.2 million, partially offset by a decrease in securities sold under agreements to repurchase of $2.0 million .

Deposits increase d $130.3 million , or 4.6% , to $2.97 billion at June 30, 2018 , as compared to $2.84 billion at December 31, 2017 . The increase was attributable to increase s of $213.3 million in certificates of deposit, and $20.2 million in brokered deposits, partially offset by decreases of $39.8 million in transaction accounts, $56.3 million in money market accounts, and $7.1 million in savings accounts.

Borrowings and securities sold under agreements to repurchase increase d by $52.8 million , or 11.2% , to $524.3 million at June 30, 2018 , from $471.5 million at December 31, 2017 . 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 overnight borrowings) and the weighted average rate by year at June 30, 2018 (dollars in thousands):



Year	Amount	Weighted Average Rate

2022	20,000	1.97%
Thereafter	75,000	2.85%

Total stockholders’ equity increase d by $10.8 million to $649.7 million at June 30, 2018 , from $638.9 million at December 31, 2017 . The increase was primarily attributable to net income of $21.1 million for the six months ended June 30, 2018 , and to a lesser extent a $5.2 million increase related to ESOP and equity award activity. These increases were partially offset by dividend payments of $9.3 million and a $6.2 million increase in unrealized losses on our securities available-for-sale portfolio as a result of the increased interest rate environment.

Comparison of Operating Results for the Six Months Ended June 30, 2018 and 2017

Net Income. Net income was $21.1 million and $18.4 million for the six months ended June 30, 2018 , and June 30, 2017 , respectively.

Interest Income . Interest income increased $5.9 million , or 9.1% , to $70.6 million for the six months ended June 30, 2018 , from $64.7 million for the six months ended June 30, 2017 , due to an increase in the average balance of interest-earning assets of $266.1 million , or 7.4% , and a six basis point increase in the yields earned on average interest-earning assets. Interest income on loans increased by $3.6 million , primarily attributable to an increase in the average loan balances of $144.7 million and a five basis point increase in the average yield on loans as a result of the recent increases in market interest rates.

Interest Expense . Interest expense increased $4.2 million , or 37.3% , to $15.3 million for the six months ended June 30, 2018 , as compared to $11.1 million for six months ended June 30, 2017 , due to a $3.7 million increase in interest expense on deposits and a $418,000 increase in interest expense on borrowings. The increase in interest expense on deposits was attributed to a 24 basis point increase in the cost of interest-bearing deposits to 0.90% for the six months ended June 30, 2018 , as compared to 0.66% for the comparable prior year period and an increase in the average balance of interest-bearing deposit accounts of $232.7 million , or 10.1% , to $2.53 billion for the six months ended June 30, 2018 , from $2.30 billion for the six months ended June 30, 2017 .

Net Interest Income . Net interest income for the six months ended June 30, 2018 , increase d $1.7 million , or 3.2% , to $55.3 million , from $53.6 million for the six months ended June 30, 2017 , primarily due to a $266.1 million , or 7.4% , increase in our average interest-earning assets, partially offset by a 12 basis point decrease in our net interest margin to 2.89% from 3.01% for the six months ended June 30, 2017 . The increase in average interest-earning assets was due to increases in average loans outstanding of $144.7 million , average mortgage-backed securities of $64.0 million , average other securities of $49.4 million , and average interest-earning deposits in financial institutions of $9.3 million , partially offset by a decrease in average Federal Home Loan Bank of New York ( “FHLBNY”) stock of $1.3 million . The increase in average loans was primarily due to strong originated loan growth as well as loan pool purchases during the first quarter of 2018. Yields earned on interest-earning assets increased six basis points to 3.69% for the six months ended June 30, 2018 , from 3.63% for the six months ended June 30, 2017 , driven by higher yields on all asset classes. The cost of interest-bearing liabilities increased 23 basis points to 1.03% for the current period as compared to 0.80% for the comparable prior year period, due to higher rates on interest-bearing deposits and borrowed funds, attributable to the rising rate environment.

Provision for Loan Losses . The provision for loan losses decrease d by $179,000 to $ 704,000 for the six months ended June 30, 2018 , from $883,000 for the six months ended June 30, 2017 , primarily due to improving asset quality trends, including a decrease in criticized loans, and an improvement in historical loss rates. Net recoveries for the six months ended June 30, 2018 , were $18,000 , as compared to net recoveries of $127,000 for the six months ended June 30, 2017 .

Non-interest Income . Non-interest income decrease d $1.7 million , or 26.4% , to $4.8 million for the six months ended June 30, 2018 , from $6.6 million for the six months ended June 30, 2017 , primarily due to a decrease of $1.6 million in income on bank owned life insurance, attributable to insurance proceeds in excess of the related cash surrender value of the policies, received in the first quarter of 2017, and a decrease of $191,000 in gains on securities transactions, net. Securities gains, net, during the six months ended June 30, 2018 , included gains of $302,000 related to the Company’s trading portfolio, compared to gains of $668,000 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 the 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 remained level at $34.2 million for both six-month periods ended June 30, 2018 and June 30, 2017.

Income Tax Expense . The Company recorded income tax expense of $4.2 million for the six months ended June 30, 2018 , compared to $6.8 million for the six months ended June 30, 2017 . The effective tax rate for the six months ended June 30, 2018 , was 16.8% compared to 26.9% for the six months ended June 30, 2017 , reflecting the reduction of the federal statutory corporate tax rate to 21% from 35% by the Tax Reform Act, partially offset by lower excess tax benefits. Excess tax benefits were $2.1 million for the current period as compared to $2.3 million for the prior year period. Excess tax benefits will fluctuate throughout the year based on the Company's stock price and timing of employee stock option exercises and vesting of other share-based awards. The Company has approximately 335,000 options outstanding at June 30, 2018, from its 2009 grants which expire on January 30, 2019, at a weighted average price of $7.09 per share and a weighted average grant date fair value of $2.30 per share. To the extent these options are exercised during the remainder of 2018, this will result in additional tax benefits which will have a positive effect on our effective tax rate. The effective tax rate for the six months ended June 30, 2017, benefited from $1.5 million of tax-exempt income from bank owned life insurance proceeds in excess of the cash surrender value of the policies.

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 ( $21.3 million at June 30, 2018 and $22.7 million at December 31, 2017 ) as accruing, even though they may be contractually past due. At June 30, 2018 , 7.1% of PCI loans were past due 30 to 89 days, and 24.1% were past due 90 days or more, as compared to 10.8% and 17.1%, respectively, at December 31, 2017 .

Originated and Acquired loans

The following table details total originated and acquired (including held-for-sale, but excluding PCI) non-accruing loans, non-performing loans, non-performing assets, troubled debt restructurings (TDRs) on which interest is accruing, and accruing loans 30 to 89 days delinquent at June 30, 2018 , and December 31, 2017 (dollars in thousands):

Loans Subject to TDR Agreements

Included in non-accruing loans are loans subject to TDR agreements totaling $517,000 and $251,000 at June 30, 2018 , and December 31, 2017 , respectively. At June 30, 2018 , $276,000, or 53.4%, of the non-accruing TDRs were not performing in accordance with their restructured terms, comprised of two separate relationships. The loans are adequately collateralized by real estate with an aggregate appraised value of $825,000. At December 31, 2017, the $251,000 non-accruing TDR was comprised of one loan collateralized by real estate with an appraised value of $629,000.

The Company also holds loans subject to restructuring agreements that are on accrual status totaling $16.8 million and $18.0 million at June 30, 2018 , and December 31, 2017 , respectively. At June 30, 2018 , and December 31, 2017 , all of the accruing TDR loans were performing in accordance with their restructured terms. Generally, types of concessions that we make to troubled borrowers include both temporary and permanent reductions to interest rates, extension of payment terms, and, to a lesser extent, forgiveness of principal and interest.

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, 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 FHLBNY, 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 $475.6 million at June 30, 2018 , and had a weighted average interest rate of 1.85% . A total of $135.6 million of these borrowings will mature in less than one year. Borrowed funds, excluding capitalized lease obligations, floating rate advances, and overnight line of credit, were $466.2 million at December 31, 2017 . The Bank has the ability to obtain additional funding from the FHLB and Federal Reserve Bank of New York's discount window of approximately $1.04 billion utilizing unencumbered securities of $321.4 million and loans of $722.5 million at June 30, 2018 . 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 June 30, 2018 , Northfield Bancorp, Inc. (standalone) had liquid assets of $15.8 million.

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. For calendar year 2018, the capital conservation buffer is 1.875%.

As a result of the recently enacted Economic Growth, Regulatory Relief, and Consumer Protection Act, the federal banking agencies are required to develop a “Community Bank Leverage Ratio” (the ratio of a bank’s tangible equity capital to average total consolidated assets) for financial institutions with assets of less than $10 billion. A “qualifying community bank” that exceeds this ratio will be deemed to be in compliance with all other capital and leverage requirements, including the capital requirements to be considered “well capitalized” under Prompt Corrective Action statutes. The federal banking agencies may consider a financial institution’s risk profile when evaluating whether it qualifies as a community bank for purposes of the capital ratio requirement. The federal banking agencies must set the minimum capital for the new Community Bank Leverage Ratio at not less than 8% and not more than 10%. A financial institution can elect to be subject to this new definition.

Table of Contents

At June 30, 2018 , and December 31, 2017 , as set forth in the following table, both the Bank and Northfield Bancorp, Inc. exceeded all of the regulatory capital requirements to which they were subject at such dates.



	Northfield Bank	Northfield Bancorp, Inc.	For Capital Adequacy Purposes ⁽¹⁾	For Well Capitalized Under Prompt Corrective Action Provisions

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 June 30, 2018 (in thousands):



Contractual Obligations	Total		Less than One Year ⁽¹⁾		One to less than Three Years		Three to less than Five Years		More than Five Years
Debt obligations (excluding capitalized leases)	$	524,160	$	184,160	$	221,725	$	105,775	$	12,500
Commitments to originate loans	97,917		97,917		—		—		—
Commitments to fund unused lines of credit	103,600		103,600		—		—		—

⁽¹⁾ Includes $5.1 million of floating rate advances and $43.5 million overnight line of credit.

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, 2017 .

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 securities 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 Asset-Liability Committee (“MALCO”), comprised of our SVP & Chief Investment Officer and Treasurer, who chairs this Committee, our President and Chief Executive Officer, our EVP & Chief Administrative Officer, EVP & Chief Financial Officer, EVP & Chief Lending Officer, EVP Operations, EVP & Director of Business Development and SVP & Director of Marketing, and other officers and staff as necessary or appropriate to manage interest rate risk. 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 have shorter maturities than one-to-four family residential real estate loans and have higher interest rates that generally reset from five to ten years;


•	investing in shorter-term investment grade corporate securities and mortgage-backed securities; and


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

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 June 30, 2018 , and December 31, 2017 , 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 June 30, 2018 , in the event of a 200 basis point decrease in interest rates, we would experience a 5.19% increase in estimated net portfolio value and a 0.79% increase in net interest income in year one and a 0.27% decrease in net interest income in year two. In the event of a 400 basis point increase in interest rates, we would experience a 17.24% decrease in estimated net portfolio value and a 11.92% decrease in net interest income in year one and a 4.93% decrease in net interest income in year two. 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 and 22% in year two. 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 June 30, 2018 , 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.
