Notes to Consolidated Financial Statements

1.Basis of Financial Statement Presentation

The accompanying unaudited consolidated financial statements include the accounts of Columbia Financial, Inc., its wholly-owned subsidiary Columbia Bank (the "Bank") and the Bank's wholly-owned subsidiaries (collectively, the “Company”). In consolidation, all intercompany accounts and transactions are eliminated.

Columbia Financial, Inc. is a majority-owned subsidiary of Columbia Bank, MHC (the "MHC"). The accounts of the MHC are not consolidated in the accompanying consolidated financial statements of the Company.

In preparing the interim unaudited consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the consolidated statements of financial condition and consolidated statements of income for the periods presented. Actual results could differ from these estimates. Material estimates that are particularly susceptible to change are the determination of the adequacy of the allowance for loan losses, evaluation of the need for valuation allowances on deferred tax assets, and determination of liabilities related to retirement and other post-retirement benefits. These estimates and assumptions are evaluated on an ongoing basis and are adjusted when facts and circumstances dictate.

The interim unaudited consolidated financial statements reflect all normal and recurring adjustments, which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. The results of operation for the three months ended March 31, 2019 are not necessarily indicative of the results of operation that may be expected for all of 2019. Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications.

The interim unaudited consolidated financial statements of the Company presented herein have been prepared in accordance with the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and U.S. generally accepted accounting principles (“GAAP”). Certain information and note disclosures have been condensed or omitted pursuant to the rules and regulations of the SEC.

These unaudited consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2018 and the audited consolidated financial statements included therein.

2.Earnings per Share

Basic earnings per share ("EPS") is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. For purposes of calculating basic EPS, weighted average common shares outstanding excludes unallocated employee stock ownership plan shares that have not been committed for release and deferred compensation obligations required to be settled in shares of Company stock.

Diluted EPS is computed using the same method as basic EPS and reflects the potential dilution which could occur if stock options and unvested shares were exercised and converted into common stock. The potentially diluted shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method. For the three months ended March 31, 2019 and 2018, the Company did not have any stock options outstanding.

3.     Summary of Significant Accounting Policies

Accounting Pronouncements Adopted in 2019

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 Post-retirement Benefit Cost, which requires that companies disaggregate the service cost component from other components of net benefit cost. This update calls for companies that offer post-retirement 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 costs component and outside the subtotal of income from operations, if one is presented. The effective date for this ASU for the Company is fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company adopted this guidance effective January 1, 2019. See note 9 for additional disclosure regarding the impact of adoption of this ASU 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, a new standard which addresses diversity in practice related to eight specific cash flow issues: debt prepayment or extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that

are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies), distributions received from equity method investees, beneficial interests in securitization

transactions and separately identifiable cash flows and application of the predominance principle. This guidance in the ASU is effective for the Company for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Entities will apply the standard’s provisions using a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company adopted this guidance effective January 1, 2019. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments- Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. This guidance requires an entity to: (i) measure equity investments at fair value through net income, with certain exceptions; (ii) present in other comprehensive income the changes in instrument-specific credit risk for financial liabilities measured using the fair value option; (iii) present financial assets and financial liabilities by measurement category and form of financial asset; (iv) calculate the fair value of financial instruments for disclosure purposes based on an exit price; and (v) assess a valuation

allowance on deferred tax assets related to unrealized losses on available-for-sale debt securities in combination with other deferred tax assets. This guidance provides an election to subsequently measure certain non-marketable equity investments at cost less any impairment and adjusted for certain observable price changes.

Notes to Consolidated Financial Statements

3.    Summary of Significant Accounting Policies (continued)

Accounting Pronouncements Adopted in 2019 (continued)

The guidance also requires a qualitative impairment assessment of such equity investments and amends certain fair value disclosure requirements. The guidance in the ASU is effective for the Company for annual periods beginning after December 15, 2018.

The Company adopted this guidance effective January 1, 2019. As a result, $1.9 million of equity securities, as of December 31, 2018, were reclassified from securities available for sale, and presented as a separate line item on the consolidated statements of financial condition. The $548,000 after tax unrealized gain on these securities, at time of adoption, was reclassified from other comprehensive income (loss) to retained earnings, and is reflected in the consolidated statements of changes in stockholders' equity. For financial instruments that are measured at amortized cost, the Company measures fair value utilizing an exit price methodology. See note 10 for additional disclosure regarding the impact of adoption of this ASU on the Company's consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The objective of this amendment is to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP. This update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts are in the scope of other standards. The guidance in the ASU was effective for the Company for fiscal years beginning after December 15, 2018. Subsequently, the FASB issued various amendments that were intended to improve and clarify the implementation guidance of ASU No. 2014-09 and had the same effective date as the original guidance. The Company's revenue is primarily comprised of net interest income on interest earning assets and liabilities and non-interest income. The scope of guidance explicitly excludes net interest income as well as other revenues associated with financial assets and liabilities, including loans, leases, securities and derivatives. The Company adopted the guidance effective January 1, 2019, after completing an evaluation of the Company's revenue streams and applicable revenue recognition, and concluded that there are no material changes related to the timing or amount of revenue recognition. The adoption of this guidance did not have a significant impact on the Company's consolidated financial statements, but resulted in additional footnote disclosures, including the disaggregation of certain categories of revenues. See note 13 for additional disclosure regarding the impact of adoption of this ASU on the Company's consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

In October 2018, the FASB issued ASU No. 2018-16, Derivatives and Hedging (Topic 815)- Inclusion of the Secured Overnight Financing Rate ("SOFR") Overnight Index Swap ("OIS") Rate as a Benchmark Interest Tate for Hedge Accounting Purposes. This ASU permits the use of the OIS rate based upon SOFR as a U.S. benchmark interest rate for purposes of applying hedge accounting under Topic 815. This is the fifth U.S. benchmark interest rate eligible for use in hedge accounting in addition to the direct Treasury obligations of the U.S. Government, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the Securities Industry and Financial Markets Association Municipal Swap Rate. The amendments in this ASU are required to be adopted concurrently with the amendments in ASU No. 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities, which was issued in August 2017. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The effective date for this ASU for the Company is for fiscal years beginning after December 15, 2019, with early adoption, including adoption in an interim period, permitted. ASU 2017-12 requires a modified retrospective transition method in which the company will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company does not expect the adoption of this guidance to have a significant impact on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820):Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The purpose of this updated guidance is to improve the effectiveness and disclosures in the notes to the financial statements. The ASU removes the requirement to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; removes the policy for timing of transfers between levels; and removes the disclosure related to the valuation process for Level 3 fair value measurements. The ASU also modifies existing disclosure requirements which relate to the disclosure for investments in certain entities which calculate net asset value and clarifies the disclosure about uncertainty in the measurements as of the reporting date.

3.    Summary of Significant Accounting Policies (continued)

Accounting Pronouncements Not Yet Adopted (continued)

For all entities, the effective date for this guidance is fiscal years beginning after December 15, 2019, including interim periods within the reporting period, with early adoption permitted. Entities are also allowed to elect early adoption of the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until their effective date. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. The amendments in this update modify the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing disclosures that no longer are considered cost beneficial, clarifying the specific requirements of disclosures, and adding disclosure requirements identified as relevant. Among other changes, the ASU adds disclosure requirements to Topic 715-20 for the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates and an explanation of the reasons for significant gains and losses related to changes in benefit obligation for the period. The amendments remove disclosure requirements for the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, the amount and timing of plan assets expected to be returned to the employer, and the effects of a one-percentage-point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of net periodic benefit costs and (b) benefit obligation for post-retirement health care benefits. ASU 2018-14 is effective for fiscal years beginning after December 15, 2020, including interim reporting periods within that reporting period, with early adoption permitted. The update is to be applied on a retrospective basis. The Company will evaluate the effect of ASU 2018-14 on its disclosures in the Company's consolidated financial statements.

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. This guidance shortens the amortization period for premiums on callable debt securities by requiring that premiums be amortized to the first (or earliest) call date instead of as an adjustment to the yield over the contractual life. This change more closely aligns the accounting with the economics of a callable debt security and the amortization period with expectations that already are included in market pricing on callable debt securities. This guidance does not change the accounting for discounts on callable debt securities, which will continue to be amortized to the maturity date. This guidance includes only instruments that are held at a premium and have explicit call features. It does not include instruments that contain prepayment features, such as mortgage backed securities; nor does it include call options that are contingent upon future events or in which the timing or amount to be paid is not fixed. The effective date for this ASU for the Company is fiscal years beginning after December 15, 2019, including interim periods within the reporting period, with early adoption permitted. Transition is on a modified retrospective basis with an adjustment to retained earnings as of the beginning of the period of adoption. If early adopted in an interim period, adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The Company does not expect the adoption of this ASU to have a significant impact on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The main objective of this guidance is to simplify the accounting for goodwill impairment by requiring that impairment charges be based upon the first step in the current two-step impairment test under ASC 350. Currently, if the fair value of a reporting unit is lower than its carrying amount (Step 1), an entity calculates any impairment charge by comparing the implied fair value of goodwill with its carrying amount (Step 2). The implied fair value of goodwill is calculated by deducting the fair value of all assets and liabilities of the reporting unit from the reporting unit’s fair value as determined in Step 1. To determine the implied fair value of goodwill, entities estimate the fair value of any unrecognized intangible assets and any corporate-level assets or liabilities that were included in the determination of the carrying amount and fair value of the reporting unit in Step 1. Under this guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. This guidance eliminates the requirement to calculate a goodwill impairment charge using Step 2. This guidance does not change the guidance on completing Step 1 of the goodwill impairment test. Under this guidance, an entity will still be able to perform the current optional qualitative goodwill impairment assessment before determining whether to proceed to Step 1. The guidance in the ASU will be applied prospectively and is effective for the Company for annual and interim impairment tests performed in periods beginning after December 15, 2019. The Company does not expect the adoption of this ASU to have a significant impact on its consolidated financial statements.

3.    Summary of Significant Accounting Policies (continued)

Accounting Pronouncements Not Yet Adopted (continued)

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments. This guidance provides financial statement users with more decision-useful information about expected credit losses on financial instruments by a reporting entity at each reporting date. The amendments of this guidance require financial assets measured at amortized cost to be presented at the net amount expected to be collected.

The allowance for credit losses would represent a valuation account that would be deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The income statement would reflect the measurement of credit losses that have taken place during the period.

The measurement of expected credit losses would be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity would be required to use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The guidance in the ASU is effective for the Company for fiscal years beginning after December 15, 2019, including interim periods within that reporting period. Early adoption is permitted. The Company is currently evaluating its existing systems and data to support the new standard as well as assessing the impact that the guidance will have on the Company's consolidated financial statements. The Company has formed a working group under the direction of the Chief Financial Officer that is primarily comprised of individuals from various functional areas including finance, credit, risk management, and operations, among others. A detailed implementation plan was developed which includes an assessment of the processes, portfolio segmentation, model development and validation, and system requirements and resources needed. The Company has engaged a third-party vendor to assist with model development, data governance and operational controls to support the adoption of this ASU. Furthermore, this ASU will necessitate establishing an allowance for expected credit losses on debt securities. The Company has begun its evaluation of the guidance including the potential impact on its consolidated financial statements. The extent of the change is indeterminable at this time as it will be dependent upon portfolio composition and credit quality at the adoption date, as well as economic conditions and forecasts at that time. Upon adoption, any impact to the allowance for credit losses will have an impact on retained earnings.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This guidance requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date for leases classified as operating leases as well as finance leases. The update also requires new quantitative disclosures related to leases in the Company's consolidated financial statements. There are also practical expedients in this update related to leases that commenced before the effective date, initial direct costs and the use of hindsight to extend or terminate a lease or purchase a leased asset. Lessor accounting remains largely unchanged under this new guidance. In January 2018, the FASB issued ASU 2018-01, Leases (Topic 842)-Land Easement Practical Expedient for Transition to Topic 842, which provides an optional practical expedient to not evaluate land easements which were existing or expired before the adoption of Topic 842 that were not accounted for as leases under Topic 840. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842) -Targeted Improvements which provides entities with an optional transition method under which comparative periods presented in the financial statements will continue to be in accordance with current Topic 840, Leases, and a practical expedient to not separate non-lease components from the associated lease component. The guidance is effective for the Company for annual periods beginning after December 15, 2019, including interim periods within that reporting period. During the quarter ended March 31, 2019 , the Company identified the inventory of leases and actively accumulated the requisite lease data necessary to apply the guidance. In addition, a software platform was selected which will support the recording, accounting and disclosure requirements of the new lease guidance. The Company is continuing its efforts to evaluate the impact of this guidance and, as such, no conclusions have yet been reached regarding the potential impact on adoption on the Company's consolidated financial statements; however, the Company does not expect the adoption to have a material impact on its results of operations.

The Company evaluates securities for other-than-temporary impairment at each reporting period and more frequently when economic or market conditions warrant such evaluation. The temporary loss position associated with debt securities available for sale was the result of changes in market interest rates relative to the coupon of the individual security and changes in credit spreads. The Company does not have the intent to sell securities in a temporary loss position at March 31, 2019, nor is it more likely than not that the Company will be required to sell the securities before the anticipated recovery.

The number of securities in an unrealized loss position as of March 31, 2019 totaled 133, compared with 151 at December 31, 2018. All temporarily impaired securities were investment grade as of March 31, 2019 and December 31, 2018.

The Company did not record an other-than-temporary impairment charge on debt securities available for sale for the three months ended March 31, 2019 and 2018.

The Company considers a loan to be delinquent when we have not received a payment within 30 of its contractual due date. Generally, a loan is designated as a non-accrual loan when the payment of interest is 90 or more in arrears of its contractual due date. The accrual of income on a non-accrual loan is reversed and discontinued until the outstanding payments in arrears have been collected and there is a sustained period of performance. The Company identifies loans that may need to be charged-off as a loss, by reviewing all delinquent loans, classified loans and other loans that management may have concerns about collectability. At March 31, 2019 and December 31, 2018, non-accrual loans totaled $6.8 million and $2.8 million, respectively. Included in non-accrual loans at March 31, 2019, are three loans to one borrower totaling $2.4 million that are not delinquent but have been identified as having circumstances that indicate a concern regarding continued collectability.

At March 31, 2019 and December 31, 2018, there were no loans past due 90 days or more and still accruing interest.

Loan modifications to borrowers experiencing financial difficulties that are considered troubled debt restructurings ("TDRs") primarily involve the lowering of the monthly payments on such loans through either a reduction in interest rate below a market rate, an extension of the term of the loan without a corresponding adjustment to the risk premium reflected in the interest rate, or a combination of these two methods. These modifications generally do not result in the forgiveness of principal or accrued interest. In addition, the Company attempts to obtain additional collateral or guarantor support when modifying such loans. Non-accruing restructured loans may be returned to accrual status when there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible.

The Company utilizes an eight-point risk rating system to summarize its loan portfolio into categories with similar risk characteristics. Loans deemed to be “acceptable quality” are rated 1 through 4 (Pass), with a rating of 1 established for loans with minimal risk. Loans that are deemed to be of “questionable quality” are rated 5 (Special Mention) or 6 (Substandard). Loans with adverse classifications are rated 7 (Doubtful) or 8 (Loss). The risk ratings are also confirmed through periodic loan review examinations which are currently performed by both an independent third-party and the Company's credit risk review department. The Company requires an annual review be performed above certain dollar thresholds, depending on loan type, to help determine the appropriate risk ratings. Results from examinations are presented to the Audit Committee of the Board of Directors.

9.    Components of Net Periodic Benefit Cost

Pension Plan, Retirement Income Maintenance Plan (the "RIM Plan") and Post-retirement Plan

The Company maintains a single employer, tax-qualified defined benefit pension plan (the "Pension Plan") which covers full-time employees that satisfy the plan eligibility requirements. The benefits are based on years of service and the employee's compensation during the last five years of employment. Effective October 1, 2018, employees hired by the Bank are not eligible to participate in the Bank's pension plan as the plan has been closed to new employees as of that date.

The Company also has a Retirement Income Maintenance Plan (the "RIM "Plan) which is a non-qualified defined benefit plan which provides benefits to all employees of the Company if their benefits under the Pension Plan are limited by Internal Revenue Code 415 and 401(a)(17).    

In addition, the Company provides certain health care and life insurance benefits to eligible retired employees under a Post-retirement Plan. The Company accrues the cost of retiree health care and other benefits during the employees’ period of active service. Effective January 1, 2019, the Post-retirement Plan has been closed to new hires. The Company also provides life insurance benefits to eligible employees under an endorsement split-dollar life insurance program.

Effective January 1, 2019, the Company implemented ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-retirement Benefit Cost. Under this ASU, the FASB requires employers to report the service cost component in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net periodic benefit cost are required to be presented in the consolidated statements of income separately from the service cost component. The table above details the affected line items within the consolidated statements of income related to the net periodic benefits costs for the periods noted. This ASU is also required to be applied retrospectively to all periods presented.

The following table summarizes the impact of retrospective application to the consolidated statement of income for the three months ended March 31, 2018:

	Three Months Ended
	March 31, 2018
	(In thousands)
Compensation and employee benefits:
As previously reported	$	16,525
As reported under new guidance	18,050
Other non-interest expense:
As previously reported	$	3,075
As reported under new guidance	1,550

In its consolidated financial statements for the year ended December 31, 2018, the Company previously disclosed that it does not expect to contribute to the Pension Plan in 2019. As of March 31, 2019, no contributions have been made to the Pension Plan. The net periodic cost (income) for pension benefits and other post-retirement benefits for the three months ended March 31, 2019 were calculated using the actual December 31, 2018 benefit valuations.

10.    Fair Value Measurements

The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. Where quoted market values in an active market are not readily available, the Company utilizes various valuation techniques to estimate fair value.

In January 2016, the FASB issued ASU 2016-01- "Financial Instruments". This guidance amended existing guidance to improve accounting standards for financial instruments including clarification and simplification of the accounting and disclosure requirements and the requirement for public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. The Company adopted the guidance effective January 1, 2019, and the fair value of the Company's loan portfolio is now presented using an exit price method.

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:

Level 1:     Unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to

access on the measurement date.

Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar instruments in markets that are active or not active, or inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3: Prices or valuation techniques that require unobservable inputs that are both significant to the fair value measurement and unobservable (i.e., supported by minimal or no market activity). Valuation techniques include the use of option pricing models, discounted cash flow models and similar techniques.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The valuation techniques are based upon the unpaid principal balance only and exclude any accrued interest or dividends at the measurement date. Interest income and expense and dividend income are recorded within the consolidated statements of income depending on the nature of the instrument using the effective interest method based on the discount or premium.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The methods described below were used to measure fair value of financial instruments as reflected in the tables below on a recurring basis as of March 31, 2019 and December 31, 2018.

Debt Securities Available for Sale, at Fair Value

For debt securities available for sale, fair value was estimated using a market approach. The majority of these securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to a benchmark or to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company may hold debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs.

Equity Securities, at Fair Value

The Company holds equity securities that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs.

Derivatives

The Company records all derivatives included in other assets and liabilities on the consolidated statements of financial condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. At March 31, 2019 and December 31, 2018, interest rate derivatives resulting from a service provided to certain qualified borrowers in loan related transactions which are not used to manage interest rate risk are included in the Company's other assets and other liabilities. As such, the changes in fair value of these types of derivatives are recognized directly in earnings.

The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs.

The following tables present the assets and liabilities reported on the consolidated statements of financial condition at their fair values as of March 31, 2019 and December 31, 2018, by level within the fair value hierarchy:

There were no transfers between Level 1, Level 2 and Level 3 during the three months ended March 31, 2019 and March 31, 2018.

There were no Level 3 assets measured at fair value on a recurring basis at March 31, 2019 and December 31, 2018.

Assets Measured at Fair Value on a Non-Recurring Basis

The valuation techniques described below were used to estimate fair value of financial instruments measured on a non-recurring basis as of March 31, 2019 and December 31, 2018.

Collateral Dependent Impaired Loans

Loans which meet certain criteria are evaluated individually for impairment. For loans measured for impairment based on the fair value of the underlying collateral, fair value was estimated using a market approach. The Company measures the fair value of collateral underlying impaired loans primarily through obtaining independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraisers’ market knowledge and experience, as well as adjustments for estimated costs to sell between 6.0% and 8.0%. The Company classifies these loans as Level 3 within the fair value hierarchy.

Real Estate Owned

Assets acquired through foreclosure or deed in lieu of foreclosure are carried at fair value, less estimated costs to sell between 6.0% and 8.0%. Fair value is generally based on independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraiser's market knowledge and experience, and are classified as Level 3. 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. Operating results from real estate owned, including rental income, operating expenses, and gains and losses realized from the sales of real estate owned are recorded as incurred.

Mortgage Servicing Rights, Net ("MSR's")

Mortgage servicing rights are carried at the lower of cost or estimated fair value. The estimated fair value of MSRs is

obtained through an analysis of future cash flows, incorporating assumptions that market participants would use in determining fair

value including market discount rates, prepayments speeds, servicing income, servicing costs, default rates and other market driven

data, including the market's perception of future interest rate movements. The prepayment speed and the discount rate are considered

two of the most significant inputs in the model. A significant degree of judgment is involved in valuing the mortgage servicing rights

using Level 3 inputs. The use of different assumptions could have a significant effect on this fair value estimate.

The following tables present the asset and liabilities reported on the consolidated statements of financial condition at their fair values as of March 31, 2019 and December 31, 2018, by level within the fair value hierarchy:

Other Fair Value Disclosures

The Company is required to disclose estimated fair value of financial instruments, both assets and liabilities on and off the balance sheet, for which it is practicable to estimate fair value. A description of the valuation methodologies used for those assets and liabilities not recorded at fair value on a recurring or non-recurring basis are set forth below.

Cash and Cash Equivalents

For cash and due from banks, federal funds sold and short-term investments, the carrying amount approximates fair value due to their nature and short-term maturities.

Debt Securities Held to Maturity

For debt securities held to maturity, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to a benchmark or to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs within the fair value hierarchy.

Federal Home Loan Bank Stock ("FHLB")

The fair value of FHLB stock is based on redemption at par value and can only be sold to the issuing FHLB, to other FHLBs, or to other member banks. As such, the Company's FHLB stock is recorded at cost, or par value, and is evaluated for impairment each reporting period by considering the ultimate recoverability of the investment rather than temporary declines in value. The Company classifies the estimated fair value as Level 2 within the fair value hierarchy.

Loans Receivable

Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial mortgage, residential mortgage, commercial, construction, and consumer and other. Each loan category is further segmented into fixed and adjustable rate interest terms and into performing and non-performing categories.

The fair value of performing loans was estimated using a combination of techniques, including a discounted cash flow model that utilizes a discount rate that reflects the Company's curring pricing for loans with similar characteristics and remaining maturity, adjusted by an amount for estimated credit losses inherent in the portfolio at the balance sheet date. The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, when applicable. The Company classifies the estimated fair value of its loan portfolio as Level 3.

The fair value for significant non-performing loans was based on recent external appraisals of collateral securing such loans, adjusted for the timing of anticipated cash flows. The Company classifies the estimated fair value of its non-performing loan portfolio as Level 3.

In accordance with the prospective adoption of ASU 2016-01, the fair value of loans was measured using the exit price method as of March 31, 2019. The fair value of loans was measured using the entry price notion as of December 31, 2018.

Deposits

The fair value of deposits with no stated maturity, such as demand, money market, and savings and club deposits are payable on demand at each reporting date and classified as Level 2. The estimated fair value of certificates of deposit was based on the discounted value of contractual cash flows. The discount rate was estimated using the Company’s current rates offered for deposits with similar remaining maturities. The Company classifies the estimated fair value of its certificates of deposit portfolio as Level 2.

Borrowed Funds

The fair value of borrowed funds was estimated by discounting future cash flows using rates available for debt with similar terms and maturities and is classified by the Company as Level 2 within the fair value hierarchy.

Commitments to Extend Credit and Letters of Credit

The fair value of commitments to extend credit and letters of credit was 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 counter-parties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value estimates of commitments to extend credit and letters of credit are deemed immaterial in comparison to their carrying value.

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 limited markets exist for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, 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. Significant assets and liabilities that are not considered financial assets or liabilities include goodwill and other intangibles, deferred tax assets, office properties and equipment, and bank-owned life insurance. 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.

12.     Derivatives and Hedging Activities

The Company is party to interest rate derivatives that may be designated as hedging instruments. The Company offers currency forward contracts and interest rate swap contracts to certain commercial banking customers to manage their risk of exposure and risk management strategies. These contracts are simultaneously hedged by offsetting contracts with a third party, such that the Company would minimize its net risk exposure resulting from these transactions. In addition, the Company executes interest rate swaps with third parties to in order to hedge the interest expense of short-term FHLB advances. These contracts are simultaneously hedged with short-term FHLB advances.

Currency Forward Contracts. At March 31, 2019 and December 31, 2018, the Company had no currency forward contracts in place with commercial banking customers. Derivatives not designated in qualifying hedging relationships are not speculative and result from a service the Company provides to certain qualified commercial banking customers and are not used to manage interest rate risk in the Company's assets or liabilities.

Interest Rate Swaps. At March 31, 2019 the Company had interest rate swaps in place with four commercial banking customers hedged by offsetting interest rate swaps with third parties, with an aggregated notional amount of $68.7 million. At December 31, 2018, the Company had interest rate swaps in place with three commercial banking customers hedged by offsetting interest rate swaps with third parties, with an aggregated notional amount of $36.6 million. These derivatives are not designated as hedges and are not speculative. These interest rate swaps do not meet hedge accounting requirements. Changes in the fair value of both the customer swap and offsetting third party swap are recognized directly in earnings.

At March 31, 2019 and December 31, 2018, the Company had 27 and 24 interest rate swaps with notional amounts of $385.0 million and $320.0 million, respectively, hedging certain FHLB advances. These interest rate swaps meet the hedge accounting requirements. The effective portion of changes in the fair value of the derivatives designated that qualify as cash flow hedges are recorded in accumulated other comprehensive income (loss).

The ineffective portion of changes in the fair value of the derivatives designated that qualify as cash flow hedges are recorded in earnings. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counter-party in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount.

For the three months ended March 31, 2019 and 2018, the Company did not record any hedge ineffectiveness associated with these contracts.

The tables below present the fair value of the Company’s derivative financial instruments as well as their classification in the consolidated statements of financial condition at March 31, 2019 and December 31, 2018:

For the three months ended March 31, 2019 and 2018, losses of $67,000 and zero, respectively, were recorded for changes in fair value of interest rate swaps with third parties.

At March 31, 2019 and December 31, 2018, accrued interest was $14,000 and $65,000, respectively.

The Company has agreements with counterparties that contain a provision that if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default of its derivative obligations.

At March 31, 2019, the termination value of derivatives in a net liability position, which includes accrued interest, was $6.1 million. The Company has collateral posting thresholds with certain derivative counterparties, and has posted collateral of $9.1 million against its obligations under these agreements.

13.     Revenue Recognition

On January 1, 2019, the Company adopted ASU 2014-09 Revenue from Contracts with Customers (Topic 606) and all subsequent ASUs that modified Topic 606. The Company performed a review and assessment of all revenue streams, the related contracts with customers, and the underlying performance obligations in those contracts. This guidance does not apply to revenue associated with financial instruments, including interest income on loans and securities, which comprise the majority of the Company's revenue. Revenue-generating activities that are within the scope of Topic 606, are components of non-interest income. These revenue streams can generally be classified as demand deposit account fees, title insurance fees and other fees.

The Company, using a modified retrospective transition approach, determined that there was no cumulative effect adjustment to retained earnings as a result of adopting the new standard, nor did the standard have a material impact on our consolidated financial statements including the timing or amounts of revenue recognized.

13.     Revenue Recognition (continued)

The following table presents non-interest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three months ended March 31, 2019 and 2018.

	For the Three Months Ended March 31,
	2019		2018
	(In thousands)
Non-interest income
In-scope of Topic 606:
Demand deposit account fees	$	959	$	944
Title insurance fees	1,041		774
Other non-interest income	1,063		1,090
Total in-scope non-interest income	3,063		2,808
Total out-of-scope non-interest income	2,974		1,735
Total non-interest income	$	6,037	$	4,543

Demand deposit account fees include monthly maintenance fees and service charges. These fees are generally derived as a result of either transaction-based or serviced-based services. The Company's performance obligation for these services is generally satisfied, and revenue recognized, at the time the transaction is completed or the service rendered. Fees for these services are generally received from the customer either at the time of the transaction or monthly.

Title insurance fees are generally recognized at the time the transaction closes or when the service is rendered.

Other non-interest income includes check printing fees, traveler's check fees, gift card fees, branch service fees, overdraft fees, account analysis fees, other deposit related fees, wealth management related fee income which includes annuity fees, brokerage commissions, and asset management fees. Wealth management related fee income represent fees earned from customers as consideration for asset management and investment advisory services provided by a third party. The Company's performance obligation is generally satisfied monthly and the resulting fees are recognized monthly based upon the month-end market value of the assets under management and the applicable fee rate. The Company does not earn performance-based incentives. The Company's performance obligation for these transaction-based services are generally satisfied, and related revenue recognized, at the time the transaction closes or when the service is rendered or a point in time when the service is completed.

Also included in other fees are debit card and ATM fees which are transaction-based. Debit card revenue is primarily comprised of interchange fees earned when a customer's Company card is processed through a card payment network. ATM fees are largely generated when a Company cardholder uses a non-Company ATM, or a non-Company cardholder uses a Company ATM. The Company's performance obligation for these services is satisfied when the service is rendered. Payment is generally received at the time of transaction or monthly.

Out-of-scope non-interest income primarily consists of income from bank-owned life insurance, loan prepayment and servicing fees, net fees on loan level swaps, gains and losses on the sale of loans and securities, and changes in the fair value of equity securities. None of these revenue streams are subject to the requirements of Topic 606.

Comparison of Financial Condition at March 31, 2019 and December 31, 2018

Total assets increased $125.3 million, or 1.9%, to $6.8 billion at March 31, 2019 from $6.7 billion at December 31, 2018. The increase in total assets was primarily attributable to increases in debt securities available for sale of $57.3 million, debt securities held to maturity of $25.4 million, and loans receivable, net of $31.7 million.

Cash and due from banks increased $23.0 million, or 54.6%, to $65.0 million at March 31, 2019 from $42.1 million at December 31, 2018, as a portion of cash flows from deposits were not yet deployed into higher yielding assets.

Debt securities available for sale increased $57.3 million, or 5.5%, to $1.1 billion at March 31, 2019 from $1.0 billion at December 31, 2018. The increase was mainly attributable to purchases of $65.4 million in mortgage-backed securities and corporate bonds, partially offset by maturities of $797,000 in municipal securities, and repayments on mortgage-backed securities. Debt securities held to maturity increased $25.4 million, or 9.7%, to $287.5 million at March 31, 2019 from $262.1 million at December 31, 2018. The increase was mainly attributable to purchases of $28.4 million in mortgage-backed securities and corporate bonds, partially offset by repayments on mortgage-backed securities.

Loans receivable, net, increased $31.7 million, or 0.6%, to $4.9 billion at March 31, 2019 from $4.9 billion at December 31, 2018. The increase was mainly attributable to increases in construction and commercial business loans of $46.0 million and $5.6 million, respectively, partially offset by decreases in multifamily and commercial real estate and home equity loans and advances of $9.7 million and $10.3 million, respectively. Residential one-to-four family mortgage loans remained flat due to lower originations and loan sales. Overall loans increased nominally during the quarter, as the level of repayments on loans increased from previous quarters and competition for new loan originations remained strong.

Office properties and equipment increased $6.2 million, or 12.0%, to $58.3 million at March 31, 2019 from $52.1 million at December 31, 2018. The increase is primarily attributable to the purchase of a branch facility previously leased by the Bank, and increases in building improvements related to various banking office and corporate headquarter renovations.

Total liabilities increased $102.9 million, or 1.8%, to $5.8 billion at March 31, 2019 from $5.7 billion at December 31, 2018. The increase is primarily attributable to an increase in total deposits of $192.8 million, or 4.4%, partially offset by a decrease in borrowings of $90.5 million, or 7.6%. The increase in total deposits is primarily attributable to higher certificates of deposit and interest-bearing transaction account balances. The decrease in borrowings is the result of repayments of $60.0 million in maturing long-term borrowings, partially offset by $53.5 million in new long-term borrowings, coupled with a net decrease of $84.0 million in short-term borrowings.

40

Total stockholders’ equity increased $22.4 million, or 2.3%, to $994.5 million at March 31, 2019 from $972.1 million at December 31, 2018. The net increase was primarily attributable to net income of $14.9 million, coupled with improved fair market values on debt securities within our available for sale portfolio.

Comparison of Results of Operations for the Quarter Ended March 31, 2019 and March 31, 2018

Net income of $14.9 million was recorded for the quarter ended March 31, 2019, an increase of $3.1 million, or 26.6%, compared to $11.8 million for the quarter ended March 31, 2018. The increase in net income was primarily attributable to a $3.3 million increase in net interest income, a $1.6 million decrease in provision for loan losses and a $1.5 million increase in total non-interest income, partially offset by a $3.5 million increase in total non-interest expense.

Net interest income was $42.4 million for the quarter ended March 31, 2019, an increase of $3.3 million, or 8.5%, from $39.1 million for the quarter ended March 31, 2018. The increase in net interest income was attributable to an $11.1 million increase in interest income, which was partially offset by a $7.8 million increase in interest expense. The increase in interest income for the quarter ended March 31, 2019 was largely due to increases in both the average balances and yields on loans and securities.

The Company's net interest margin for the quarter ended March 31, 2019 decreased 10 basis points to 2.70%, when compared to 2.80% for the quarter ended March 31, 2018. The weighted average yield on interest-earning assets increased 29 basis points to 4.00% for the quarter ended March 31, 2019 as compared to 3.71% for the quarter ended March 31, 2018. The average cost of interest-bearing liabilities increased 60 basis points to 1.69% for the quarter ended March 31, 2019 as compared to 1.09% for the quarter ended March 31, 2018. Increases in yields and costs for the quarter ended March 31, 2019 reflect the increase in market interest rates that occurred throughout 2018.

The average yield on loans for the quarter ended March 31, 2019 increased 29 basis points to 4.25%, as compared to 3.96% for the quarter ended March 31, 2018, and the yield on securities for the quarter ended March 31, 2019 increased 19 basis points to 2.93%, as compared to 2.74% for the quarter ended March 31, 2018. Increases in yields for the quarter ended March 31, 2019 reflect the increase in market interest rates that occurred throughout 2018. The average yield on other interest-earning assets for the quarter ended March 31, 2019 increased 386 basis points to 6.62%, as compared to 2.76% for the quarter ended March 31, 2018. This was mainly a result of the 2019 average balance including mostly higher yielding Federal Home Loan Bank stock, while the 2018 average balance included higher cash deposits related to the subscriptions for the minority stock offering earning a lower rate of interest.

Total interest expense was $20.5 million for the quarter ended March 31, 2019, an increase of $7.8 million, or 61.1%, from $12.7 million. The increase in interest expense was primarily attributable to a $311.8 million increase in the average balance of certificates of deposit combined with a 61 basis point increase in the cost of deposits. The increase in interest on deposits was driven by higher market rates and a shift in the mix from core deposits to higher costing certificates of deposit. The increase in interest on borrowings was attributable to an increase in the average balance of Federal Home Loan Bank advances combined with a 64 basis point increase in the cost of these borrowings.

The provision for loan losses was $436,000 for the quarter ended March 31, 2019, a decrease of $1.6 million, or 78.2%, from $2.0 million for the quarter ended March 31, 2018. The decrease was primarily driven by improved credit metrics resulting from the quarterly assessment of qualitative factors, coupled with nominal growth in our loan portfolio. Net charge offs decreased to $7,000 for the quarter ended March 31, 2019, as compared to $226,000 for the quarter ended March 31, 2018.

Non-interest income was $6.0 million for the quarter ended March 31, 2019, an increase of $1.5 million, or 32.9%, from $4.5 million for the quarter ended March 31, 2018. The increase was attributable to: income from loan fees increasing $347,000, or 73.4%, related to swap income; title insurance fee income increasing $267,000, or 34.5%, given higher overall volume of loan closings; income from bank-owned life insurance increasing $256,000, or 24.1%, given the purchase of an additional $30 million of insurance in the third quarter of 2018; and other non-interest income increasing $291,000, or 24.8%, due to an increase in miscellaneous income.

Non-interest expense was $29.6 million for the quarter ended March 31, 2019, an increase of $3.5 million, or 13.6%, from $26.0 million for the quarter ended March 31, 2018. The increase was driven primarily by increases of $1.5 million, or 8.5%, in compensation and employee benefits, $541,000, or 63.9%, in advertising expense, $465,000, or 59.5%, in professional fees and $900,000, or 58.1%, in other non-interest expense. The higher compensation and employee benefits expense was the result of the costs associated with a newly created employee stock ownership plan, new hires, and other performance-based compensation. The increase in advertising expense was related to costs associated with the opening of our new branch in Newark, New Jersey and marketing of our competitive loan and deposit products. The increase in professional fees was the result of higher legal and accounting fees commensurate with being a public company. A new pension accounting standard, effective January 1, 2019, requires that other components of net periodic benefit costs be reported separately from the service cost component in the statements of income as a component of non-interest expense and is reflected in other non-interest expense. The increase in other non-interest expense was mainly due to a decrease of $368,000 in the credit

41

associated with these pension benefit costs, coupled with an increase of $395,000 in costs for amortization of software related to investments in new technology.

Income tax expense was $3.5 million for the quarter ended March 31, 2019, a decrease of $298,000, or 7.8%, from $3.8 million for the quarter ended March 31, 2018. The Company's effective tax rate was 19.03% and 24.41% for the quarters ended March 31, 2019 and 2018, respectively. The decrease in the effective tax rate for the three months ended March 31, 2019 was primarily driven by maximizing the tax benefits related to a subsidiary of the Bank, along with other previously implemented tax strategies.

Asset Quality

The Company's total non-performing loans at March 31, 2019 totaled $6.8 million, or 0.14% of total gross loans, as compared to $2.8 million, or 0.06% of total gross loans, at December 31, 2018. The increase of $4.0 million in non-performing loans was mainly attributable to increases of $1.9 million in one-to-four family real estate loans, $1.7 million in construction loans and $438,000 in commercial business loans. The current period increase in one-to-four family loans was mainly attributable to the addition of a $1.4 million real estate loan. The $1.7 million construction loan and two non-performing commercial business loans totaling $660,000 are related to one borrower. These three loans were placed into a non-accrual status as of March 31, 2019 as there were concerns regarding their collectability, despite the fact that these loans were not delinquent. The Company had no real estate owned at March 31, 2019 compared to one property owned with a carrying value of $92,000 at December 31, 2018. Non-performing assets as a percentage of total assets totaled 0.10% at March 31, 2019 as compared to 0.04% at December 31, 2018.

The Company's allowance for loan losses was $62.8 million, or 1.26% of total loans, at March 31, 2019, compared to $62.3 million, or 1.26% of total loans, at December 31, 2018.

Critical Accounting Policies

The Company considers certain accounting policies to be critically important to the fair presentation of its consolidated statements of financial condition and consolidated statements of income. These policies require management to make judgments on matters which by their nature have elements of uncertainty. The sensitivity of the Company’s consolidated financial statements to these critical accounting policies, and the assumptions and estimates applied, could have a significant impact on its financial condition and results of operations. These assumptions, estimates and judgments made by management can be influenced by a number of factors, including the general economic environment. The Company has identified the following as critical accounting policies:

▪Adequacy of the allowance for loan losses

▪Valuation of retirement and post-retirement benefits

▪Valuation of deferred tax assets

The calculation of the allowance for loan losses is a critical accounting policy of the Company. The allowance for loan losses is a valuation account that reflects management’s evaluation of the probable losses in the loan portfolio. Determining the amount of the allowance for loan losses involves a high degree of judgment. Estimates required to establish the allowance include: the overall economic environment, value of collateral, strength of guarantors, loss exposure in the event of default, the amount and timing of future cash flows on impaired loans, and determination of loss factors applied to the portfolio segments. These estimates are susceptible to significant change. Management regularly reviews loss experience within the portfolio and monitors current economic conditions and other factors related to the collectability of the loan portfolio.

The Company maintains the allowance for loan losses through provisions for loan losses which are charged to income. Charge-offs against the allowance for loan losses are taken on loans where management determines that the collection of loan principal is unlikely. Recoveries made on loans that have been charged-off are credited to the allowance for loan losses.

As part of the evaluation of the adequacy of the allowance for loan losses, management prepares an analysis each quarter that categorizes the entire loan portfolio by certain risk characteristics such as loan type (residential mortgage, commercial mortgage, construction, commercial, etc.) and loan risk rating.

When assigning a risk rating to a loan, management utilizes an eight-point internal risk rating system. Loans deemed to be “acceptable quality” are rated 1 through 4, with a rating of 1 established for loans with minimal risk. Loans deemed to be of “questionable quality” are rated 5 (Special Mention) or 6 (Substandard). Loans with adverse classifications are rated 7 (Doubtful) or 8 (Loss). The risk ratings are also confirmed through periodic loan review examinations, which are currently performed by both an independent third-party and the Company's internal loan review department. The Company requires an annual review be performed above certain dollar thresholds, depending on loan type, to help determine the appropriate risk rating. Results are presented to the Audit Committee of the Board of Directors.

42

Management estimates the amount of loan losses for groups of loans collectively evaluated for impairment by applying quantitative loss factors to the loan segments at the risk rating level and applying qualitative adjustments to each loan segment at the risk rating level. Quantitative loss factors give consideration to historical loss experience and migration experience by loan type based upon an appropriate look-back period, adjusted for a loss emergence period.

Qualitative adjustments give consideration to other qualitative or environmental factors such as trends and levels of delinquencies, impaired loans, charge-offs, recoveries and loan volumes, as well as national and local economic trends and conditions.

Qualitative adjustments reflect risks in the loan portfolio not captured by the quantitative loss factors and, as such, are evaluated from a risk level perspective relative to the risk levels present over the look-back period. The reserves resulting from the application of both the quantitative experience and qualitative factors are combined to arrive at the allowance for loan losses for loans collectively evaluated for impairment.

Management believes the primary risks inherent in the portfolio are a general decline in the economy, a decline in real estate market values, rising unemployment, elevated unemployment, increasing vacancy rates, and increases in interest rates in the absence of economic improvement. Any one or a combination of these events may adversely affect a borrower's ability to repay its loan, resulting in increased delinquencies and loan losses. Accordingly, the Company has recorded loan losses at a level which is estimated to represent the current risk in its loan portfolio. Management considers it important to maintain the ratio of the allowance for loan losses to total loans at an acceptable level considering the current composition of the loan portfolio.

Although management believes that the Company has established and maintained the allowance for loan losses at appropriate levels, additional reserves may be necessary if future economic and other conditions differ substantially from the current operating environment. Management evaluates its estimates and assumptions on an ongoing basis and the estimates and assumptions are adjusted when facts and circumstances necessitate a re-valuation of the estimate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. In addition, regulatory agencies periodically review the adequacy of the Company’s allowance for loan losses as an integral part of their examination process. Such agencies may require the Company to recognize additions to the allowance or additional write-downs based on their judgments about information available to them at the time of their examination. Although management uses the best information available, the level of the allowance for loan losses remains an estimate that is subject to significant judgment.

The determination of whether deferred tax assets will be realizable is predicated on the reversal of existing deferred tax liabilities, utilization against carry-back years, and estimates of future taxable income. Such estimates are subject to management’s judgment. A valuation allowance is established when management is unable to conclude that it is more likely than not that it will realize deferred tax assets based on the nature and timing of these items. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income tax expense in the period enacted. Based on all available evidence, a valuation allowance was established for the portion of the state tax benefit that is not more likely than not to be realized. At March 31, 2019 and December 31, 2018, the Company's gross deferred tax assets totaled $51.8 million and $52.1 million, respectively, while the valuation allowance totaled $3.8 million and $2.4 million, respectively.

The Company provides certain health care and life insurance benefits to eligible retired employees. The cost of retiree health care and other benefits during the employees' period of active service are accrued monthly. The accounting guidance requires the following: a) recognizing in the statement of financial position the over funded or underfunded status of a defined benefit post-retirement plan measured as the difference between the fair value of plan assets and the benefit obligations; b) measuring a plan's assets and its obligations that determine its funded status as of the end of the Company's fiscal year (with limited exceptions); and c) recognizing as a component of other comprehensive income (loss), net of tax, the actuarial gain and losses and the prior service costs and credits that arise during the period.

Item 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Qualitative Analysis.Interest rate risk is defined as the exposure of a Company's current and future earnings and capital arising from adverse movements in interest rates. The guidelines of the Company’s interest rate risk policy seek to limit the exposure to changes in interest rates that affect the underlying economic value of assets, liabilities, earnings and capital.

The Asset/Liability Committee meets regularly to review the impact of interest rate changes on net interest income, net interest margin, net income, and the economic value of equity. The Asset/Liability Committee reviews a variety of strategies that project changes in asset or liability mix and the impact of those changes on projected net interest income and net income.

The Company’s strategy for liabilities has been to maintain a stable funding base by focusing on core deposit accounts. The Company’s ability to retain maturing time deposit accounts is the result of its strategy to remain competitively priced within its marketplace. The Company’s pricing strategy may vary depending upon current funding needs and the ability of the Company to fund operations through alternative sources.

43

Quantitative Analysis. Current and future sensitivity to changes in interest rates are measured through the use of balance sheet and income simulation models. The analysis captures changes in net interest income using flat rates as a base and rising and declining interest rate forecasts. Changes in net interest income and net income for the forecast period, generally twelve to twenty-four months, are measured and compared to policy limits for acceptable changes. The Company periodically reviews historical deposit re-pricing activity and makes modifications to certain assumptions used in its balance sheet and income simulation models regarding the interest rate sensitivity of deposits. These modifications are made to more closely reflect the most likely results under the various interest rate change scenarios. Since it is inherently difficult to predict the sensitivity of interest bearing deposits to changes in interest rates, the changes in net interest income due to changes in interest rates cannot be precisely predicted. There are a variety of reasons that may cause actual results to vary considerably from the predictions presented below which include, but are not limited to, the timing, magnitude, and frequency of changes in interest rates, interest rate spreads, prepayments, and actions taken in response to such changes.

Assumptions used in the simulation model may include but are not limited to:

•Investment pricing from third parties;

•Loan pricing indications from third parties;

•Loan and depository spread assumptions based upon the Company's product offerings;

•Investment and borrowing spreads based upon third party indications; and

•Prepayment assumptions derived from the Company's actual results and third party surveys.

The table below sets forth, as of March 31, 2019, Columbia Bank's net portfolio value, the estimated changes in our net portfolio value, and the net interest income that would result from the designated instantaneous parallel changes in market interest rates. This data is for Columbia Bank and its subsidiaries only and does not include any assets of Columbia Financial, Inc.

	Twelve Months Net Interest Income							Net Portfolio Value ("NPV")
	Amount		Dollar Change			Percent of Change		Estimated NPV		Present Value Ratio		Percent Change
Change in Interest Rates (Basis Points)
+200	$	161,206	$	2,449		1.54	%	$	888,781	14.02	%	(14.03	)%
+100	160,482		1,725			1.09		974,297		14.85		(5.76	)
Base	158,757		—			—		1,033,886		15.27		—
-100	155,771		(2,986		)	(1.88	)	1,053,635		15.14		1.91
-200	150,356		(8,401		)	(5.29	)	1,031,952		14.43		(0.19	)

As of March 31, 2019, based on the scenarios above, net interest income would increase by approximately 1.54% if rates were to rise 200 basis points, but would decrease by 5.29% if rates were to decrease 200 basis points over a one-year time horizon.

Another measure of interest rate sensitivity is to model changes in net portfolio value through the use of immediate and sustained interest rate shocks. As of March 31, 2019, based on the scenarios above, in the event of an immediate and sustained 200 basis point increase in interest rates, the NPV is projected to decrease 14.03%. If rates were to decrease 200 basis points, the model forecasts a 0.19% decrease in the NPV.

Certain shortcomings are inherent in the methodologies used in the above interest rate risk measurements. Modeling changes in net interest income requires the use of certain assumptions regarding prepayment and deposit repricing, which may or may not reflect the manner in which actual yields and costs respond to changes in market interest rates. While management believes such assumptions are reasonable, there can be no assurance that assumed prepayment rates and repricing rates will approximate actual future loan prepayment and deposit repricing activity.

Moreover, net interest income assumes that the composition of interest sensitive assets and liabilities existing at the beginning of a period remains constant over the period being measured and also assumes that a particular change in interest rates is reflected uniformly across the yield curve regardless of the duration to maturity or repricing of specific assets and liabilities. Accordingly, although the net interest income table provides an indication of the Company’s interest rate risk exposure at a particular point in time, such measurement is not intended to and does not provide a precise forecast of the effect of changes in market interest rates on the Company’s net interest income and will differ from actual.

Liquidity Management and Capital Resources:

Liquidity Management. Liquidity refers to the Company's ability to generate adequate amounts of cash to meet financial obligations of a short-term and long-term nature. Sources of funds consist of deposit inflows, loan repayments and maturities, maturities and sales of securities, and the ability to execute new borrowings. While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows, calls of debt securities, and prepayments on loans and mortgage-based securities are influenced by economic conditions, competition, and interest rate movements.

The Company's cash flows are identified as cash flows from operating activities, investing activities and financing activities. Refer to the consolidated statements of cash flows for further details of the cash inflows and outflows of the Company.

Capital Resources. The Company and its subsidiary Bank are subject to various regulatory capital requirements administered by the federal banking regulators, including a risk-based capital measure. The Federal Reserve establishes capital requirements, including well capitalized standards, for the consolidated financial holding company, and the OCC has similar requirements for the Company's subsidiary bank. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's consolidated statements of financial condition. Federal regulators require federally insured depository institutions to meet several minimum capital standards: (1) total capital to risk-weighted assets of 8.0%; (2) tier 1 capital to risk-weighted assets of 6.0%; (3) common equity tier 1 capital to risk-weighted assets of 4.5%; and (4) tier 1 capital to adjusted total assets of 4.0%. 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 common equity tier 1 capital to risk-weighted assets above the amount necessary to meet its minimum risk-based capital requirements. The capital conservation buffer capital requirement was fully phased in on January 1, 2019. The regulators established a framework for the classification of savings institutions into five categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. Generally, an institution is considered well capitalized if it has: a total capital to risk-weighted assets ratio of at least 10.0%, a tier 1 capital to risk-weighted assets ratio of at least 8.0%, a common tier 1 capital to risk-weighted assets ratio of at least 6.5%, and a tier 1 capital to adjusted total assets ratio of at least 5.0%. As of March 31, 2019 and December 31, 2018, each of the Company and the Bank exceeded all capital adequacy requirements to which it is subject.

The following table presents the Company's and the Bank's actual capital amounts and ratios as of March 31, 2019 and December 31, 2018 compared to the Federal Reserve Bank minimum capital adequacy requirements and the Federal Reserve Bank requirements for classification as a well-capitalized institution:

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 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Financial Statement Presentation

Basis of Financial Statement Presentation

The accompanying unaudited consolidated financial statements include the accounts of Columbia Financial, Inc., its wholly-owned subsidiary Columbia Bank (the "Bank") and the Bank's wholly-owned subsidiaries (collectively, the “Company”). In consolidation, all intercompany accounts and transactions are eliminated.

Columbia Financial, Inc. is a majority-owned subsidiary of Columbia Bank, MHC (the "MHC"). The accounts of the MHC are not consolidated in the accompanying consolidated financial statements of the Company.

In preparing the interim unaudited consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the consolidated statements of financial condition and consolidated statements of income for the periods presented. Actual results could differ from these estimates. Material estimates that are particularly susceptible to change are the determination of the adequacy of the allowance for loan losses, evaluation of the need for valuation allowances on deferred tax assets, and determination of liabilities related to retirement and other post-retirement benefits. These estimates and assumptions are evaluated on an ongoing basis and are adjusted when facts and circumstances dictate.

The interim unaudited consolidated financial statements reflect all normal and recurring adjustments, which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. The results of operation for the three months ended March 31, 2019 are not necessarily indicative of the results of operation that may be expected for all of 2019. Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications.

The interim unaudited consolidated financial statements of the Company presented herein have been prepared in accordance with the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and U.S. generally accepted accounting principles (“GAAP”). Certain information and note disclosures have been condensed or omitted pursuant to the rules and regulations of the SEC.

These unaudited consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2018 and the audited consolidated financial statements included therein.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings per Share

Basic earnings per share ("EPS") is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. For purposes of calculating basic EPS, weighted average common shares outstanding excludes unallocated employee stock ownership plan shares that have not been committed for release and deferred compensation obligations required to be settled in shares of Company stock.

Diluted EPS is computed using the same method as basic EPS and reflects the potential dilution which could occur if stock options and unvested shares were exercised and converted into common stock. The potentially diluted shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method. For the three months ended March 31, 2019 and 2018, the Company did not have any stock options outstanding.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Accounting Pronouncements Adopted in 2019

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 Post-retirement Benefit Cost, which requires that companies disaggregate the service cost component from other components of net benefit cost. This update calls for companies that offer post-retirement 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 costs component and outside the subtotal of income from operations, if one is presented. The effective date for this ASU for the Company is fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company adopted this guidance effective January 1, 2019. See note 9 for additional disclosure regarding the impact of adoption of this ASU 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, a new standard which addresses diversity in practice related to eight specific cash flow issues: debt prepayment or extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that

are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies), distributions received from equity method investees, beneficial interests in securitization

transactions and separately identifiable cash flows and application of the predominance principle. This guidance in the ASU is effective for the Company for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Entities will apply the standard’s provisions using a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company adopted this guidance effective January 1, 2019. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments- Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. This guidance requires an entity to: (i) measure equity investments at fair value through net income, with certain exceptions; (ii) present in other comprehensive income the changes in instrument-specific credit risk for financial liabilities measured using the fair value option; (iii) present financial assets and financial liabilities by measurement category and form of financial asset; (iv) calculate the fair value of financial instruments for disclosure purposes based on an exit price; and (v) assess a valuation

allowance on deferred tax assets related to unrealized losses on available-for-sale debt securities in combination with other deferred tax assets. This guidance provides an election to subsequently measure certain non-marketable equity investments at cost less any impairment and adjusted for certain observable price changes.

3.    Summary of Significant Accounting Policies (continued)

Accounting Pronouncements Adopted in 2019 (continued)

The guidance also requires a qualitative impairment assessment of such equity investments and amends certain fair value disclosure requirements. The guidance in the ASU is effective for the Company for annual periods beginning after December 15, 2018.

The Company adopted this guidance effective January 1, 2019. As a result, $1.9 million of equity securities, as of December 31, 2018, were reclassified from securities available for sale, and presented as a separate line item on the consolidated statements of financial condition. The $548,000 after tax unrealized gain on these securities, at time of adoption, was reclassified from other comprehensive income (loss) to retained earnings, and is reflected in the consolidated statements of changes in stockholders' equity. For financial instruments that are measured at amortized cost, the Company measures fair value utilizing an exit price methodology. See note 10 for additional disclosure regarding the impact of adoption of this ASU on the Company's consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The objective of this amendment is to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP. This update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts are in the scope of other standards. The guidance in the ASU was effective for the Company for fiscal years beginning after December 15, 2018. Subsequently, the FASB issued various amendments that were intended to improve and clarify the implementation guidance of ASU No. 2014-09 and had the same effective date as the original guidance. The Company's revenue is primarily comprised of net interest income on interest earning assets and liabilities and non-interest income. The scope of guidance explicitly excludes net interest income as well as other revenues associated with financial assets and liabilities, including loans, leases, securities and derivatives. The Company adopted the guidance effective January 1, 2019, after completing an evaluation of the Company's revenue streams and applicable revenue recognition, and concluded that there are no material changes related to the timing or amount of revenue recognition. The adoption of this guidance did not have a significant impact on the Company's consolidated financial statements, but resulted in additional footnote disclosures, including the disaggregation of certain categories of revenues. See note 13 for additional disclosure regarding the impact of adoption of this ASU on the Company's consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

In October 2018, the FASB issued ASU No. 2018-16, Derivatives and Hedging (Topic 815)- Inclusion of the Secured Overnight Financing Rate ("SOFR") Overnight Index Swap ("OIS") Rate as a Benchmark Interest Tate for Hedge Accounting Purposes. This ASU permits the use of the OIS rate based upon SOFR as a U.S. benchmark interest rate for purposes of applying hedge accounting under Topic 815. This is the fifth U.S. benchmark interest rate eligible for use in hedge accounting in addition to the direct Treasury obligations of the U.S. Government, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the Securities Industry and Financial Markets Association Municipal Swap Rate. The amendments in this ASU are required to be adopted concurrently with the amendments in ASU No. 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities, which was issued in August 2017. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The effective date for this ASU for the Company is for fiscal years beginning after December 15, 2019, with early adoption, including adoption in an interim period, permitted. ASU 2017-12 requires a modified retrospective transition method in which the company will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company does not expect the adoption of this guidance to have a significant impact on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820):Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The purpose of this updated guidance is to improve the effectiveness and disclosures in the notes to the financial statements. The ASU removes the requirement to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; removes the policy for timing of transfers between levels; and removes the disclosure related to the valuation process for Level 3 fair value measurements. The ASU also modifies existing disclosure requirements which relate to the disclosure for investments in certain entities which calculate net asset value and clarifies the disclosure about uncertainty in the measurements as of the reporting date.

3.    Summary of Significant Accounting Policies (continued)

Accounting Pronouncements Not Yet Adopted (continued)

For all entities, the effective date for this guidance is fiscal years beginning after December 15, 2019, including interim periods within the reporting period, with early adoption permitted. Entities are also allowed to elect early adoption of the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until their effective date. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. The amendments in this update modify the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing disclosures that no longer are considered cost beneficial, clarifying the specific requirements of disclosures, and adding disclosure requirements identified as relevant. Among other changes, the ASU adds disclosure requirements to Topic 715-20 for the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates and an explanation of the reasons for significant gains and losses related to changes in benefit obligation for the period. The amendments remove disclosure requirements for the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, the amount and timing of plan assets expected to be returned to the employer, and the effects of a one-percentage-point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of net periodic benefit costs and (b) benefit obligation for post-retirement health care benefits. ASU 2018-14 is effective for fiscal years beginning after December 15, 2020, including interim reporting periods within that reporting period, with early adoption permitted. The update is to be applied on a retrospective basis. The Company will evaluate the effect of ASU 2018-14 on its disclosures in the Company's consolidated financial statements.

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. This guidance shortens the amortization period for premiums on callable debt securities by requiring that premiums be amortized to the first (or earliest) call date instead of as an adjustment to the yield over the contractual life. This change more closely aligns the accounting with the economics of a callable debt security and the amortization period with expectations that already are included in market pricing on callable debt securities. This guidance does not change the accounting for discounts on callable debt securities, which will continue to be amortized to the maturity date. This guidance includes only instruments that are held at a premium and have explicit call features. It does not include instruments that contain prepayment features, such as mortgage backed securities; nor does it include call options that are contingent upon future events or in which the timing or amount to be paid is not fixed. The effective date for this ASU for the Company is fiscal years beginning after December 15, 2019, including interim periods within the reporting period, with early adoption permitted. Transition is on a modified retrospective basis with an adjustment to retained earnings as of the beginning of the period of adoption. If early adopted in an interim period, adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The Company does not expect the adoption of this ASU to have a significant impact on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The main objective of this guidance is to simplify the accounting for goodwill impairment by requiring that impairment charges be based upon the first step in the current two-step impairment test under ASC 350. Currently, if the fair value of a reporting unit is lower than its carrying amount (Step 1), an entity calculates any impairment charge by comparing the implied fair value of goodwill with its carrying amount (Step 2). The implied fair value of goodwill is calculated by deducting the fair value of all assets and liabilities of the reporting unit from the reporting unit’s fair value as determined in Step 1. To determine the implied fair value of goodwill, entities estimate the fair value of any unrecognized intangible assets and any corporate-level assets or liabilities that were included in the determination of the carrying amount and fair value of the reporting unit in Step 1. Under this guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. This guidance eliminates the requirement to calculate a goodwill impairment charge using Step 2. This guidance does not change the guidance on completing Step 1 of the goodwill impairment test. Under this guidance, an entity will still be able to perform the current optional qualitative goodwill impairment assessment before determining whether to proceed to Step 1. The guidance in the ASU will be applied prospectively and is effective for the Company for annual and interim impairment tests performed in periods beginning after December 15, 2019. The Company does not expect the adoption of this ASU to have a significant impact on its consolidated financial statements.

3.    Summary of Significant Accounting Policies (continued)

Accounting Pronouncements Not Yet Adopted (continued)

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments. This guidance provides financial statement users with more decision-useful information about expected credit losses on financial instruments by a reporting entity at each reporting date. The amendments of this guidance require financial assets measured at amortized cost to be presented at the net amount expected to be collected.

The allowance for credit losses would represent a valuation account that would be deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The income statement would reflect the measurement of credit losses that have taken place during the period.

The measurement of expected credit losses would be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity would be required to use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The guidance in the ASU is effective for the Company for fiscal years beginning after December 15, 2019, including interim periods within that reporting period. Early adoption is permitted. The Company is currently evaluating its existing systems and data to support the new standard as well as assessing the impact that the guidance will have on the Company's consolidated financial statements. The Company has formed a working group under the direction of the Chief Financial Officer that is primarily comprised of individuals from various functional areas including finance, credit, risk management, and operations, among others. A detailed implementation plan was developed which includes an assessment of the processes, portfolio segmentation, model development and validation, and system requirements and resources needed. The Company has engaged a third-party vendor to assist with model development, data governance and operational controls to support the adoption of this ASU. Furthermore, this ASU will necessitate establishing an allowance for expected credit losses on debt securities. The Company has begun its evaluation of the guidance including the potential impact on its consolidated financial statements. The extent of the change is indeterminable at this time as it will be dependent upon portfolio composition and credit quality at the adoption date, as well as economic conditions and forecasts at that time. Upon adoption, any impact to the allowance for credit losses will have an impact on retained earnings.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This guidance requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date for leases classified as operating leases as well as finance leases. The update also requires new quantitative disclosures related to leases in the Company's consolidated financial statements. There are also practical expedients in this update related to leases that commenced before the effective date, initial direct costs and the use of hindsight to extend or terminate a lease or purchase a leased asset. Lessor accounting remains largely unchanged under this new guidance. In January 2018, the FASB issued ASU 2018-01, Leases (Topic 842)-Land Easement Practical Expedient for Transition to Topic 842, which provides an optional practical expedient to not evaluate land easements which were existing or expired before the adoption of Topic 842 that were not accounted for as leases under Topic 840. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842) -Targeted Improvements which provides entities with an optional transition method under which comparative periods presented in the financial statements will continue to be in accordance with current Topic 840, Leases, and a practical expedient to not separate non-lease components from the associated lease component. The guidance is effective for the Company for annual periods beginning after December 15, 2019, including interim periods within that reporting period. During the quarter ended March 31, 2019 , the Company identified the inventory of leases and actively accumulated the requisite lease data necessary to apply the guidance. In addition, a software platform was selected which will support the recording, accounting and disclosure requirements of the new lease guidance. The Company is continuing its efforts to evaluate the impact of this guidance and, as such, no conclusions have yet been reached regarding the potential impact on adoption on the Company's consolidated financial statements; however, the Company does not expect the adoption to have a material impact on its results of operations.

Mortgage-backed securities and collateralized mortgage obligations totaling $971.0 million at amortized cost, and $967.1 million at fair value, are not classified by maturity in the table above as their expected lives are likely to be shorter than the contractual maturity date due to principal prepayments.

4.     Debt Securities Available for Sale (continued)

During the three months ended March 31, 2019, there were no sales or calls of debt securities available for sale. Proceeds from one matured debt security available for sale totaled $797,000.

During the three months ended March 31, 2018, there were no sales of debt securities available for sale. Proceeds from one called debt security available for sale totaled $9.7 million, resulting in $116,000 of gross gains and no gross losses. No debt securities available for sale matured during the period.

Debt securities available for sale having a carrying value of $246.1 million and $232.7 million, respectively, at March 31, 2019 and December 31, 2018, respectively, were pledged as security for public funds on deposit at the Bank as required and permitted by law.

The following tables summarize the fair value and gross unrealized losses of those securities that reported an unrealized loss at March 31, 2019 and December 31, 2018 and if the unrealized loss position was continuous for the twelve months prior to those respective dates:

The Company evaluates securities for other-than-temporary impairment at each reporting period and more frequently when economic or market conditions warrant such evaluation. The temporary loss position associated with debt securities available for sale was the result of changes in market interest rates relative to the coupon of the individual security and changes in credit spreads. The Company does not have the intent to sell securities in a temporary loss position at March 31, 2019, nor is it more likely than not that the Company will be required to sell the securities before the anticipated recovery.

The number of securities in an unrealized loss position as of March 31, 2019 totaled 133, compared with 151 at December 31, 2018. All temporarily impaired securities were investment grade as of March 31, 2019 and December 31, 2018.

The Company did not record an other-than-temporary impairment charge on debt securities available for sale for the three months ended March 31, 2019 and 2018.

Debt securities held to maturity having a carrying value of $222.7 million and $187.0 million, at March 31, 2019 and December 31, 2018, respectively, were pledged as security for public funds on deposit at the Bank as required and permitted by law.

5.    Debt Securities Held to Maturity (continued)

The following tables summarize the fair value and gross unrealized losses of those securities that reported an unrealized loss at March 31, 2019 and December 31, 2018 and if the unrealized loss position was continuous for the twelve months prior to March 31, 2019 and December 31, 2018:

The Company evaluates securities for other-than-temporary impairment at each reporting period and more frequently when economic or market conditions warrant such evaluation. The temporary loss position associated with debt securities held to maturity was the result of changes in market interest rates relative to the coupon of the individual security and changes in credit spreads. The Company does not have the intent to sell securities in a temporary loss position at March 31, 2019, nor is it more likely than not that the Company will be required to sell the securities before the anticipated recovery.

The number of securities in an unrealized loss position as of March 31, 2019 totaled 76, compared with 88 at December 31, 2018. All temporarily impaired securities were investment grade as of March 31, 2019 and December 31, 2018.

The Company did not record an other-than-temporary impairment charge on debt securities held to maturity for the three months ended March 31, 2019 and 2018.

Equity Securities at Fair Value

The Company has an equity securities portfolio which consists of investments in other financial institutions and a payment technology company, which is reported at fair value on the Company's consolidated statements of financial condition. The fair value of the equities portfolio at March 31, 2019 and December 31, 2018 was $1.4 million and $1.9 million, respectively.

The Company adopted ASU 2016-01 on January 1, 2019, resulting in a $548,000 after tax cumulative-effect adjustment from other comprehensive income (loss) to retained earnings, as reflected in the consolidated statements of changes in stockholder's equity. The Company recorded the net increase in the fair value of equity securities of $176,000, during the three months ended March 31, 2019, as a component of non-interest income.

During the three months ended March 31, 2019, proceeds from sales of equity securities totaled $764,000, resulting in $126,000 of gross gains and no gross losses. There were no sales of equity securities during the three months ended March 31, 2018.

The Company considers a loan to be delinquent when we have not received a payment within 30 of its contractual due date. Generally, a loan is designated as a non-accrual loan when the payment of interest is 90 or more in arrears of its contractual due date. The accrual of income on a non-accrual loan is reversed and discontinued until the outstanding payments in arrears have been collected and there is a sustained period of performance. The Company identifies loans that may need to be charged-off as a loss, by reviewing all delinquent loans, classified loans and other loans that management may have concerns about collectability. At March 31, 2019 and December 31, 2018, non-accrual loans totaled $6.8 million and $2.8 million, respectively. Included in non-accrual loans at March 31, 2019, are three loans to one borrower totaling $2.4 million that are not delinquent but have been identified as having circumstances that indicate a concern regarding continued collectability.

At March 31, 2019 and December 31, 2018, there were no loans past due 90 days or more and still accruing interest.

Loan modifications to borrowers experiencing financial difficulties that are considered troubled debt restructurings ("TDRs") primarily involve the lowering of the monthly payments on such loans through either a reduction in interest rate below a market rate, an extension of the term of the loan without a corresponding adjustment to the risk premium reflected in the interest rate, or a combination of these two methods. These modifications generally do not result in the forgiveness of principal or accrued interest. In addition, the Company attempts to obtain additional collateral or guarantor support when modifying such loans. Non-accruing restructured loans may be returned to accrual status when there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible.

The Company utilizes an eight-point risk rating system to summarize its loan portfolio into categories with similar risk characteristics. Loans deemed to be “acceptable quality” are rated 1 through 4 (Pass), with a rating of 1 established for loans with minimal risk. Loans that are deemed to be of “questionable quality” are rated 5 (Special Mention) or 6 (Substandard). Loans with adverse classifications are rated 7 (Doubtful) or 8 (Loss). The risk ratings are also confirmed through periodic loan review examinations which are currently performed by both an independent third-party and the Company's credit risk review department. The Company requires an annual review be performed above certain dollar thresholds, depending on loan type, to help determine the appropriate risk ratings. Results from examinations are presented to the Audit Committee of the Board of Directors.

Retirement Benefits [Abstract]

Components of Net Periodic Benefit Costs

.    Components of Net Periodic Benefit Cost

Pension Plan, Retirement Income Maintenance Plan (the "RIM Plan") and Post-retirement Plan

The Company maintains a single employer, tax-qualified defined benefit pension plan (the "Pension Plan") which covers full-time employees that satisfy the plan eligibility requirements. The benefits are based on years of service and the employee's compensation during the last five years of employment. Effective October 1, 2018, employees hired by the Bank are not eligible to participate in the Bank's pension plan as the plan has been closed to new employees as of that date.

The Company also has a Retirement Income Maintenance Plan (the "RIM "Plan) which is a non-qualified defined benefit plan which provides benefits to all employees of the Company if their benefits under the Pension Plan are limited by Internal Revenue Code 415 and 401(a)(17).    

In addition, the Company provides certain health care and life insurance benefits to eligible retired employees under a Post-retirement Plan. The Company accrues the cost of retiree health care and other benefits during the employees’ period of active service. Effective January 1, 2019, the Post-retirement Plan has been closed to new hires. The Company also provides life insurance benefits to eligible employees under an endorsement split-dollar life insurance program.

Effective January 1, 2019, the Company implemented ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-retirement Benefit Cost. Under this ASU, the FASB requires employers to report the service cost component in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net periodic benefit cost are required to be presented in the consolidated statements of income separately from the service cost component. The table above details the affected line items within the consolidated statements of income related to the net periodic benefits costs for the periods noted. This ASU is also required to be applied retrospectively to all periods presented.

The following table summarizes the impact of retrospective application to the consolidated statement of income for the three months ended March 31, 2018:

	Three Months Ended

In its consolidated financial statements for the year ended December 31, 2018, the Company previously disclosed that it does not expect to contribute to the Pension Plan in 2019. As of March 31, 2019, no contributions have been made to the Pension Plan. The net periodic cost (income) for pension benefits and other post-retirement benefits for the three months ended March 31, 2019 were calculated using the actual December 31, 2018 benefit valuations.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. Where quoted market values in an active market are not readily available, the Company utilizes various valuation techniques to estimate fair value.

In January 2016, the FASB issued ASU 2016-01- "Financial Instruments". This guidance amended existing guidance to improve accounting standards for financial instruments including clarification and simplification of the accounting and disclosure requirements and the requirement for public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. The Company adopted the guidance effective January 1, 2019, and the fair value of the Company's loan portfolio is now presented using an exit price method.

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:

Level 1:     Unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to

access on the measurement date.

Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar instruments in markets that are active or not active, or inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3: Prices or valuation techniques that require unobservable inputs that are both significant to the fair value measurement and unobservable (i.e., supported by minimal or no market activity). Valuation techniques include the use of option pricing models, discounted cash flow models and similar techniques.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The valuation techniques are based upon the unpaid principal balance only and exclude any accrued interest or dividends at the measurement date. Interest income and expense and dividend income are recorded within the consolidated statements of income depending on the nature of the instrument using the effective interest method based on the discount or premium.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The methods described below were used to measure fair value of financial instruments as reflected in the tables below on a recurring basis as of March 31, 2019 and December 31, 2018.

Debt Securities Available for Sale, at Fair Value

For debt securities available for sale, fair value was estimated using a market approach. The majority of these securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to a benchmark or to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company may hold debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs.

10.    Fair Value Measurements (continued)

Equity Securities, at Fair Value

The Company holds equity securities that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs.

Derivatives

The Company records all derivatives included in other assets and liabilities on the consolidated statements of financial condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. At March 31, 2019 and December 31, 2018, interest rate derivatives resulting from a service provided to certain qualified borrowers in loan related transactions which are not used to manage interest rate risk are included in the Company's other assets and other liabilities. As such, the changes in fair value of these types of derivatives are recognized directly in earnings.

The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs.

The following tables present the assets and liabilities reported on the consolidated statements of financial condition at their fair values as of March 31, 2019 and December 31, 2018, by level within the fair value hierarchy:

There were no transfers between Level 1, Level 2 and Level 3 during the three months ended March 31, 2019 and March 31, 2018.

There were no Level 3 assets measured at fair value on a recurring basis at March 31, 2019 and December 31, 2018.

Assets Measured at Fair Value on a Non-Recurring Basis

The valuation techniques described below were used to estimate fair value of financial instruments measured on a non-recurring basis as of March 31, 2019 and December 31, 2018.

Collateral Dependent Impaired Loans

Loans which meet certain criteria are evaluated individually for impairment. For loans measured for impairment based on the fair value of the underlying collateral, fair value was estimated using a market approach. The Company measures the fair value of collateral underlying impaired loans primarily through obtaining independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraisers’ market knowledge and experience, as well as adjustments for estimated costs to sell between 6.0% and 8.0%. The Company classifies these loans as Level 3 within the fair value hierarchy.

Real Estate Owned

Assets acquired through foreclosure or deed in lieu of foreclosure are carried at fair value, less estimated costs to sell between 6.0% and 8.0%. Fair value is generally based on independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraiser's market knowledge and experience, and are classified as Level 3. 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. Operating results from real estate owned, including rental income, operating expenses, and gains and losses realized from the sales of real estate owned are recorded as incurred.

10.    Fair Value Measurements (continued)

Mortgage Servicing Rights, Net ("MSR's")

Mortgage servicing rights are carried at the lower of cost or estimated fair value. The estimated fair value of MSRs is

obtained through an analysis of future cash flows, incorporating assumptions that market participants would use in determining fair

value including market discount rates, prepayments speeds, servicing income, servicing costs, default rates and other market driven

data, including the market's perception of future interest rate movements. The prepayment speed and the discount rate are considered

two of the most significant inputs in the model. A significant degree of judgment is involved in valuing the mortgage servicing rights

using Level 3 inputs. The use of different assumptions could have a significant effect on this fair value estimate.

The following tables present the asset and liabilities reported on the consolidated statements of financial condition at their fair values as of March 31, 2019 and December 31, 2018, by level within the fair value hierarchy:

Other Fair Value Disclosures

The Company is required to disclose estimated fair value of financial instruments, both assets and liabilities on and off the balance sheet, for which it is practicable to estimate fair value. A description of the valuation methodologies used for those assets and liabilities not recorded at fair value on a recurring or non-recurring basis are set forth below.

Cash and Cash Equivalents

For cash and due from banks, federal funds sold and short-term investments, the carrying amount approximates fair value due to their nature and short-term maturities.

Debt Securities Held to Maturity

For debt securities held to maturity, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to a benchmark or to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs within the fair value hierarchy.

Federal Home Loan Bank Stock ("FHLB")

The fair value of FHLB stock is based on redemption at par value and can only be sold to the issuing FHLB, to other FHLBs, or to other member banks. As such, the Company's FHLB stock is recorded at cost, or par value, and is evaluated for impairment each reporting period by considering the ultimate recoverability of the investment rather than temporary declines in value. The Company classifies the estimated fair value as Level 2 within the fair value hierarchy.

10.    Fair Value Measurements (continued)

Loans Receivable

Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial mortgage, residential mortgage, commercial, construction, and consumer and other. Each loan category is further segmented into fixed and adjustable rate interest terms and into performing and non-performing categories.

The fair value of performing loans was estimated using a combination of techniques, including a discounted cash flow model that utilizes a discount rate that reflects the Company's curring pricing for loans with similar characteristics and remaining maturity, adjusted by an amount for estimated credit losses inherent in the portfolio at the balance sheet date. The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, when applicable. The Company classifies the estimated fair value of its loan portfolio as Level 3.

The fair value for significant non-performing loans was based on recent external appraisals of collateral securing such loans, adjusted for the timing of anticipated cash flows. The Company classifies the estimated fair value of its non-performing loan portfolio as Level 3.

In accordance with the prospective adoption of ASU 2016-01, the fair value of loans was measured using the exit price method as of March 31, 2019. The fair value of loans was measured using the entry price notion as of December 31, 2018.

Deposits

The fair value of deposits with no stated maturity, such as demand, money market, and savings and club deposits are payable on demand at each reporting date and classified as Level 2. The estimated fair value of certificates of deposit was based on the discounted value of contractual cash flows. The discount rate was estimated using the Company’s current rates offered for deposits with similar remaining maturities. The Company classifies the estimated fair value of its certificates of deposit portfolio as Level 2.

Borrowed Funds

The fair value of borrowed funds was estimated by discounting future cash flows using rates available for debt with similar terms and maturities and is classified by the Company as Level 2 within the fair value hierarchy.

Commitments to Extend Credit and Letters of Credit

The fair value of commitments to extend credit and letters of credit was 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 counter-parties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value estimates of commitments to extend credit and letters of credit are deemed immaterial in comparison to their carrying value.

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 limited markets exist for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, 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. Significant assets and liabilities that are not considered financial assets or liabilities include goodwill and other intangibles, deferred tax assets, office properties and equipment, and bank-owned life insurance. 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging Activities

Derivatives and Hedging Activities

The Company is party to interest rate derivatives that may be designated as hedging instruments. The Company offers currency forward contracts and interest rate swap contracts to certain commercial banking customers to manage their risk of exposure and risk management strategies. These contracts are simultaneously hedged by offsetting contracts with a third party, such that the Company would minimize its net risk exposure resulting from these transactions. In addition, the Company executes interest rate swaps with third parties to in order to hedge the interest expense of short-term FHLB advances. These contracts are simultaneously hedged with short-term FHLB advances.

Currency Forward Contracts. At March 31, 2019 and December 31, 2018, the Company had no currency forward contracts in place with commercial banking customers. Derivatives not designated in qualifying hedging relationships are not speculative and result from a service the Company provides to certain qualified commercial banking customers and are not used to manage interest rate risk in the Company's assets or liabilities.

Interest Rate Swaps. At March 31, 2019 the Company had interest rate swaps in place with four commercial banking customers hedged by offsetting interest rate swaps with third parties, with an aggregated notional amount of $68.7 million. At December 31, 2018, the Company had interest rate swaps in place with three commercial banking customers hedged by offsetting interest rate swaps with third parties, with an aggregated notional amount of $36.6 million. These derivatives are not designated as hedges and are not speculative. These interest rate swaps do not meet hedge accounting requirements. Changes in the fair value of both the customer swap and offsetting third party swap are recognized directly in earnings.

At March 31, 2019 and December 31, 2018, the Company had 27 and 24 interest rate swaps with notional amounts of $385.0 million and $320.0 million, respectively, hedging certain FHLB advances. These interest rate swaps meet the hedge accounting requirements. The effective portion of changes in the fair value of the derivatives designated that qualify as cash flow hedges are recorded in accumulated other comprehensive income (loss).

The ineffective portion of changes in the fair value of the derivatives designated that qualify as cash flow hedges are recorded in earnings. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counter-party in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount.

For the three months ended March 31, 2019 and 2018, the Company did not record any hedge ineffectiveness associated with these contracts.

The tables below present the fair value of the Company’s derivative financial instruments as well as their classification in the consolidated statements of financial condition at March 31, 2019 and December 31, 2018:

	March 31, 2019

For the three months ended March 31, 2019 and 2018, losses of $67,000 and zero, respectively, were recorded for changes in fair value of interest rate swaps with third parties.

At March 31, 2019 and December 31, 2018, accrued interest was $14,000 and $65,000, respectively.

The Company has agreements with counterparties that contain a provision that if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default of its derivative obligations.

At March 31, 2019, the termination value of derivatives in a net liability position, which includes accrued interest, was $6.1 million. The Company has collateral posting thresholds with certain derivative counterparties, and has posted collateral of $9.1 million against its obligations under these agreements.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Revenue Recognition

On January 1, 2019, the Company adopted ASU 2014-09 Revenue from Contracts with Customers (Topic 606) and all subsequent ASUs that modified Topic 606. The Company performed a review and assessment of all revenue streams, the related contracts with customers, and the underlying performance obligations in those contracts. This guidance does not apply to revenue associated with financial instruments, including interest income on loans and securities, which comprise the majority of the Company's revenue. Revenue-generating activities that are within the scope of Topic 606, are components of non-interest income. These revenue streams can generally be classified as demand deposit account fees, title insurance fees and other fees.

The Company, using a modified retrospective transition approach, determined that there was no cumulative effect adjustment to retained earnings as a result of adopting the new standard, nor did the standard have a material impact on our consolidated financial statements including the timing or amounts of revenue recognized.    

13.     Revenue Recognition (continued)

The following table presents non-interest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three months ended March 31, 2019 and 2018.

	For the Three Months Ended March 31,
	2019		2018
	(In thousands)
Non-interest income
In-scope of Topic 606:
Demand deposit account fees	$	959	$	944
Title insurance fees	1,041		774
Other non-interest income	1,063		1,090
Total in-scope non-interest income	3,063		2,808
Total out-of-scope non-interest income	2,974		1,735
Total non-interest income	$	6,037	$	4,543

Demand deposit account fees include monthly maintenance fees and service charges. These fees are generally derived as a result of either transaction-based or serviced-based services. The Company's performance obligation for these services is generally satisfied, and revenue recognized, at the time the transaction is completed or the service rendered. Fees for these services are generally received from the customer either at the time of the transaction or monthly.

Title insurance fees are generally recognized at the time the transaction closes or when the service is rendered.

Other non-interest income includes check printing fees, traveler's check fees, gift card fees, branch service fees, overdraft fees, account analysis fees, other deposit related fees, wealth management related fee income which includes annuity fees, brokerage commissions, and asset management fees. Wealth management related fee income represent fees earned from customers as consideration for asset management and investment advisory services provided by a third party. The Company's performance obligation is generally satisfied monthly and the resulting fees are recognized monthly based upon the month-end market value of the assets under management and the applicable fee rate. The Company does not earn performance-based incentives. The Company's performance obligation for these transaction-based services are generally satisfied, and related revenue recognized, at the time the transaction closes or when the service is rendered or a point in time when the service is completed.

Also included in other fees are debit card and ATM fees which are transaction-based. Debit card revenue is primarily comprised of interchange fees earned when a customer's Company card is processed through a card payment network. ATM fees are largely generated when a Company cardholder uses a non-Company ATM, or a non-Company cardholder uses a Company ATM. The Company's performance obligation for these services is satisfied when the service is rendered. Payment is generally received at the time of transaction or monthly.

Out-of-scope non-interest income primarily consists of income from bank-owned life insurance, loan prepayment and servicing fees, net fees on loan level swaps, gains and losses on the sale of loans and securities, and changes in the fair value of equity securities. None of these revenue streams are subject to the requirements of Topic 606.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent Accounting Pronouncement Adopted and Issued

Accounting Pronouncements Adopted in 2019

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 Post-retirement Benefit Cost, which requires that companies disaggregate the service cost component from other components of net benefit cost. This update calls for companies that offer post-retirement 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 costs component and outside the subtotal of income from operations, if one is presented. The effective date for this ASU for the Company is fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company adopted this guidance effective January 1, 2019. See note 9 for additional disclosure regarding the impact of adoption of this ASU 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, a new standard which addresses diversity in practice related to eight specific cash flow issues: debt prepayment or extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that

are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies), distributions received from equity method investees, beneficial interests in securitization

transactions and separately identifiable cash flows and application of the predominance principle. This guidance in the ASU is effective for the Company for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Entities will apply the standard’s provisions using a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company adopted this guidance effective January 1, 2019. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments- Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. This guidance requires an entity to: (i) measure equity investments at fair value through net income, with certain exceptions; (ii) present in other comprehensive income the changes in instrument-specific credit risk for financial liabilities measured using the fair value option; (iii) present financial assets and financial liabilities by measurement category and form of financial asset; (iv) calculate the fair value of financial instruments for disclosure purposes based on an exit price; and (v) assess a valuation

allowance on deferred tax assets related to unrealized losses on available-for-sale debt securities in combination with other deferred tax assets. This guidance provides an election to subsequently measure certain non-marketable equity investments at cost less any impairment and adjusted for certain observable price changes.

3.    Summary of Significant Accounting Policies (continued)

Accounting Pronouncements Adopted in 2019 (continued)

The guidance also requires a qualitative impairment assessment of such equity investments and amends certain fair value disclosure requirements. The guidance in the ASU is effective for the Company for annual periods beginning after December 15, 2018.

The Company adopted this guidance effective January 1, 2019. As a result, $1.9 million of equity securities, as of December 31, 2018, were reclassified from securities available for sale, and presented as a separate line item on the consolidated statements of financial condition. The $548,000 after tax unrealized gain on these securities, at time of adoption, was reclassified from other comprehensive income (loss) to retained earnings, and is reflected in the consolidated statements of changes in stockholders' equity. For financial instruments that are measured at amortized cost, the Company measures fair value utilizing an exit price methodology. See note 10 for additional disclosure regarding the impact of adoption of this ASU on the Company's consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The objective of this amendment is to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP. This update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts are in the scope of other standards. The guidance in the ASU was effective for the Company for fiscal years beginning after December 15, 2018. Subsequently, the FASB issued various amendments that were intended to improve and clarify the implementation guidance of ASU No. 2014-09 and had the same effective date as the original guidance. The Company's revenue is primarily comprised of net interest income on interest earning assets and liabilities and non-interest income. The scope of guidance explicitly excludes net interest income as well as other revenues associated with financial assets and liabilities, including loans, leases, securities and derivatives. The Company adopted the guidance effective January 1, 2019, after completing an evaluation of the Company's revenue streams and applicable revenue recognition, and concluded that there are no material changes related to the timing or amount of revenue recognition. The adoption of this guidance did not have a significant impact on the Company's consolidated financial statements, but resulted in additional footnote disclosures, including the disaggregation of certain categories of revenues. See note 13 for additional disclosure regarding the impact of adoption of this ASU on the Company's consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

In October 2018, the FASB issued ASU No. 2018-16, Derivatives and Hedging (Topic 815)- Inclusion of the Secured Overnight Financing Rate ("SOFR") Overnight Index Swap ("OIS") Rate as a Benchmark Interest Tate for Hedge Accounting Purposes. This ASU permits the use of the OIS rate based upon SOFR as a U.S. benchmark interest rate for purposes of applying hedge accounting under Topic 815. This is the fifth U.S. benchmark interest rate eligible for use in hedge accounting in addition to the direct Treasury obligations of the U.S. Government, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the Securities Industry and Financial Markets Association Municipal Swap Rate. The amendments in this ASU are required to be adopted concurrently with the amendments in ASU No. 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities, which was issued in August 2017. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The effective date for this ASU for the Company is for fiscal years beginning after December 15, 2019, with early adoption, including adoption in an interim period, permitted. ASU 2017-12 requires a modified retrospective transition method in which the company will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company does not expect the adoption of this guidance to have a significant impact on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820):Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The purpose of this updated guidance is to improve the effectiveness and disclosures in the notes to the financial statements. The ASU removes the requirement to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; removes the policy for timing of transfers between levels; and removes the disclosure related to the valuation process for Level 3 fair value measurements. The ASU also modifies existing disclosure requirements which relate to the disclosure for investments in certain entities which calculate net asset value and clarifies the disclosure about uncertainty in the measurements as of the reporting date.

3.    Summary of Significant Accounting Policies (continued)

Accounting Pronouncements Not Yet Adopted (continued)

For all entities, the effective date for this guidance is fiscal years beginning after December 15, 2019, including interim periods within the reporting period, with early adoption permitted. Entities are also allowed to elect early adoption of the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until their effective date. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. The amendments in this update modify the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing disclosures that no longer are considered cost beneficial, clarifying the specific requirements of disclosures, and adding disclosure requirements identified as relevant. Among other changes, the ASU adds disclosure requirements to Topic 715-20 for the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates and an explanation of the reasons for significant gains and losses related to changes in benefit obligation for the period. The amendments remove disclosure requirements for the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, the amount and timing of plan assets expected to be returned to the employer, and the effects of a one-percentage-point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of net periodic benefit costs and (b) benefit obligation for post-retirement health care benefits. ASU 2018-14 is effective for fiscal years beginning after December 15, 2020, including interim reporting periods within that reporting period, with early adoption permitted. The update is to be applied on a retrospective basis. The Company will evaluate the effect of ASU 2018-14 on its disclosures in the Company's consolidated financial statements.

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. This guidance shortens the amortization period for premiums on callable debt securities by requiring that premiums be amortized to the first (or earliest) call date instead of as an adjustment to the yield over the contractual life. This change more closely aligns the accounting with the economics of a callable debt security and the amortization period with expectations that already are included in market pricing on callable debt securities. This guidance does not change the accounting for discounts on callable debt securities, which will continue to be amortized to the maturity date. This guidance includes only instruments that are held at a premium and have explicit call features. It does not include instruments that contain prepayment features, such as mortgage backed securities; nor does it include call options that are contingent upon future events or in which the timing or amount to be paid is not fixed. The effective date for this ASU for the Company is fiscal years beginning after December 15, 2019, including interim periods within the reporting period, with early adoption permitted. Transition is on a modified retrospective basis with an adjustment to retained earnings as of the beginning of the period of adoption. If early adopted in an interim period, adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The Company does not expect the adoption of this ASU to have a significant impact on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The main objective of this guidance is to simplify the accounting for goodwill impairment by requiring that impairment charges be based upon the first step in the current two-step impairment test under ASC 350. Currently, if the fair value of a reporting unit is lower than its carrying amount (Step 1), an entity calculates any impairment charge by comparing the implied fair value of goodwill with its carrying amount (Step 2). The implied fair value of goodwill is calculated by deducting the fair value of all assets and liabilities of the reporting unit from the reporting unit’s fair value as determined in Step 1. To determine the implied fair value of goodwill, entities estimate the fair value of any unrecognized intangible assets and any corporate-level assets or liabilities that were included in the determination of the carrying amount and fair value of the reporting unit in Step 1. Under this guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. This guidance eliminates the requirement to calculate a goodwill impairment charge using Step 2. This guidance does not change the guidance on completing Step 1 of the goodwill impairment test. Under this guidance, an entity will still be able to perform the current optional qualitative goodwill impairment assessment before determining whether to proceed to Step 1. The guidance in the ASU will be applied prospectively and is effective for the Company for annual and interim impairment tests performed in periods beginning after December 15, 2019. The Company does not expect the adoption of this ASU to have a significant impact on its consolidated financial statements.

3.    Summary of Significant Accounting Policies (continued)

Accounting Pronouncements Not Yet Adopted (continued)

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments. This guidance provides financial statement users with more decision-useful information about expected credit losses on financial instruments by a reporting entity at each reporting date. The amendments of this guidance require financial assets measured at amortized cost to be presented at the net amount expected to be collected.

The allowance for credit losses would represent a valuation account that would be deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The income statement would reflect the measurement of credit losses that have taken place during the period.

The measurement of expected credit losses would be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity would be required to use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The guidance in the ASU is effective for the Company for fiscal years beginning after December 15, 2019, including interim periods within that reporting period. Early adoption is permitted. The Company is currently evaluating its existing systems and data to support the new standard as well as assessing the impact that the guidance will have on the Company's consolidated financial statements. The Company has formed a working group under the direction of the Chief Financial Officer that is primarily comprised of individuals from various functional areas including finance, credit, risk management, and operations, among others. A detailed implementation plan was developed which includes an assessment of the processes, portfolio segmentation, model development and validation, and system requirements and resources needed. The Company has engaged a third-party vendor to assist with model development, data governance and operational controls to support the adoption of this ASU. Furthermore, this ASU will necessitate establishing an allowance for expected credit losses on debt securities. The Company has begun its evaluation of the guidance including the potential impact on its consolidated financial statements. The extent of the change is indeterminable at this time as it will be dependent upon portfolio composition and credit quality at the adoption date, as well as economic conditions and forecasts at that time. Upon adoption, any impact to the allowance for credit losses will have an impact on retained earnings.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This guidance requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date for leases classified as operating leases as well as finance leases. The update also requires new quantitative disclosures related to leases in the Company's consolidated financial statements. There are also practical expedients in this update related to leases that commenced before the effective date, initial direct costs and the use of hindsight to extend or terminate a lease or purchase a leased asset. Lessor accounting remains largely unchanged under this new guidance. In January 2018, the FASB issued ASU 2018-01, Leases (Topic 842)-Land Easement Practical Expedient for Transition to Topic 842, which provides an optional practical expedient to not evaluate land easements which were existing or expired before the adoption of Topic 842 that were not accounted for as leases under Topic 840. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842) -Targeted Improvements which provides entities with an optional transition method under which comparative periods presented in the financial statements will continue to be in accordance with current Topic 840, Leases, and a practical expedient to not separate non-lease components from the associated lease component. The guidance is effective for the Company for annual periods beginning after December 15, 2019, including interim periods within that reporting period. During the quarter ended March 31, 2019 , the Company identified the inventory of leases and actively accumulated the requisite lease data necessary to apply the guidance. In addition, a software platform was selected which will support the recording, accounting and disclosure requirements of the new lease guidance. The Company is continuing its efforts to evaluate the impact of this guidance and, as such, no conclusions have yet been reached regarding the potential impact on adoption on the Company's consolidated financial statements; however, the Company does not expect the adoption to have a material impact on its results of operations.
