Notes to Consolidated Financial Statements

1.     Summary of Significant Accounting Principles

Basis of Presentation

    The consolidated financial statements are comprised of the accounts of Investors Bancorp, Inc. and its wholly owned subsidiary, Investors Bank (the “Bank”) and the Bank’s wholly-owned subsidiaries (collectively, the “Company”). In the opinion of management, all the adjustments (consisting of normal and recurring adjustments) necessary for the fair presentation of the consolidated financial condition and the consolidated results of operations for the unaudited periods presented have been included. The results of operations and other data presented for the three and nine months ended September 30, 2020 are not necessarily indicative of the results of operations that may be expected for subsequent periods or the full year results.

    Certain information and note disclosures usually included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for the preparation of the Form 10-Q. The consolidated financial statements presented should be read in conjunction with the Company’s audited consolidated financial statements and notes to the audited consolidated financial statements included in the Company’s December 31, 2019 Annual Report on Form 10-K. Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications.

Adoption of New Accounting Standards

    On January 1, 2020, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The Company adopted ASU 2016-13 using a modified retrospective approach. Results for reporting periods beginning after January 1, 2020 are presented under Topic 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP. At adoption, the Company increased its allowance for credit losses by $11.7 million, comprised of $12.7 million and $2.6 million, respectively, for unfunded commitments and held-to-maturity debt securities, partially offset by a decrease of $3.6 million for loans. Upon adoption the Company recorded a cumulative effect adjustment that reduced stockholders’ equity by $8.5 million, net of tax.

Allowance for Credit Losses    

    The allowance for credit losses includes both the allowance for loan and lease losses and the reserve for unfunded lending commitments and represents the estimated amount considered necessary to cover lifetime expected credit losses inherent in financial assets at the balance sheet date. The measurement of expected credit losses is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures such as loan commitments and unused lines of credit. The allowance is established through the provision for credit losses that is charged against income. The methodology for determining the allowance for credit losses is considered a critical accounting policy by management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment that could result in changes to the amount of the recorded allowance for credit losses. The allowance for loan and security losses is reported separately as contra-assets to loans and securities on the consolidated balance sheet. The expected credit loss for unfunded lending commitments and unfunded loan commitments is reported on the consolidated balance sheet in other liabilities. The provision for credit losses related to loans, unfunded commitments and debt securities is reported on the consolidated statement of income.

Allowance for Credit Losses on Loans Receivable

    The allowance for credit losses on loans is deducted from the amortized cost basis of the loan to present the net amount expected to be collected. Expected losses are evaluated and calculated on a collective basis for those loans which share similar risk characteristics. At each reporting period, the Company evaluates whether the loans in a pool continue to exhibit similar risk characteristics as the other loans in the pool. If the risk characteristics of a loan change, such that they are no longer similar to other loans in the pool, the Company will evaluate the loan with a different pool of loans that share similar risk characteristics. If the loan does not share risk characteristics with other loans, the Company will evaluate the allowance on an individual basis. The Company evaluates the segmentation at least annually to determine whether loans continue to share similar risk characteristics. Loans are charged off against the allowance when the Company believes the loan balances become uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged off or expected to be charged off.

    The Company has chosen to segment its portfolio consistent with the manner in which it manages the risk of the type of credit. The Company’s segments for loans include multi-family, commercial real estate, commercial and industrial, construction, residential and consumer.

    The Company calculates estimated credit loss on its loan portfolio typically using a probability of default and loss given default quantitative model methodology. The point in time probability of default and loss given default are then conditioned by macroeconomic scenarios to incorporate reasonable and supportable forecasts that affect the collectability of the reported amount. For a small portion of the loan portfolio, i.e. unsecured consumer loans, small business loans and loans to individuals, the Company utilizes a loss rate method to calculate the expected credit loss of that asset segment.

    The Company estimates the allowance for credit losses on loans using relevant available information from internal and external sources related to past events and current conditions as well as the incorporation of reasonable and supportable forecasts. The Company evaluates the use of multiple economic scenarios and the weighting of those scenarios on a quarterly basis. The scenarios that are chosen and the amount of weighting given to each scenario depend on a variety of factors including third party economists and firms, industry trends and other available published economic information.

    After the reasonable and supportable forecast period, the Company reverts to average historical losses. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by the Company.

    Also included in the allowance for loans are qualitative reserves to cover losses that are expected but, in the Company’s assessment, may not be adequately represented in the quantitative method or the economic assumptions described above. For example, factors that the Company considers include changes in lending policies and procedures, business conditions, the nature and size of the portfolio, portfolio concentrations, the volume and severity of past due loans and non-accrual loans, the effect of external factors such as competition, and the legal and regulatory requirements, among other. Furthermore, the Company considers the inherent uncertainty in quantitative models that are built on historical data.

Individually evaluated

    On a case-by-case basis, the Company may conclude a loan should be evaluated on an individual basis based on its disparate risk characteristics. The Company individually evaluates loans that meet the following criteria for expected credit loss, as the Company has determined that these loans generally do not share similar risk characteristics with other loans in the portfolio:

•Commercial loans with an outstanding balance greater than $1.0 million and on non-accrual status;

•Troubled debt restructured loans; and

•Other commercial loans with greater than $1.0 million in outstanding principal, if management has specific information that it is probable they will not collect all principal amounts due under the contractual terms of the loan agreement.

    When the Company determines that the loan no longer shares similar risk characteristics of other loans in the portfolio, the allowance will be determined on an individual basis using the present value of expected cash flows or, for collateral-dependent loans, the fair value of the collateral as of the reporting date, less estimated selling costs, as applicable, to ensure that the credit loss is not delayed until actual loss. If the fair value of the collateral is less than the amortized cost basis of the loan, the Company will charge off the difference between the fair value of the collateral, less costs to sell at the reporting date and the amortized cost basis of the loan.

Acquired assets

    Acquired assets are included in the Company's calculation of the allowance for credit losses. How the allowance on an acquired asset is recorded depends on whether it has been classified as a Purchased Financial Asset with Credit Deterioration (“PCD”). PCD assets are assets acquired at a discount that is due, in part, to credit quality. PCD assets are accounted for in accordance with ASC Subtopic 326-20 and are initially recorded at fair value as determined by the sum of the present value of expected future cash flows and an allowance for credit losses at acquisition. The allowance for PCD assets is recorded through a gross-up effect, while the allowance for acquired non-PCD assets such as loans is recorded through provision expense, consistent with originated loans. Thus, the determination of which assets are PCD and non-PCD can have a significant effect on the accounting for these assets.

    Subsequent to acquisition, the allowance for PCD loans will generally follow the same estimation, provision and

7

charge-off process as non-PCD acquired and originated loans. Additionally, TDR identification for acquired loans (PCD and non-PCD) will be consistent with the TDR identification for originated loans.

Allowance for Credit Losses on Debt Securities

    Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. Management classifies the held-to-maturity portfolio into the following major security types: mortgage-backed residential securities, municipal bonds, trust preferred securities (“TruPS”) and other. Nearly all of the mortgage-backed securities in the Company's portfolio are issued by U.S. government agencies and are either explicitly or implicitly guaranteed by the U.S government, are highly rated by major rating agencies and have a long history of no credit losses and therefore the expectation of non-payment is zero. Other securities consist primarily of investments in pooled trust preferred securities.

    At each reporting period, the Company evaluates whether the securities in a segment continue to exhibit similar risk characteristics as the other securities in the segment. If the risk characteristics of a security change, such that they are no longer similar to other securities in the segment, the Company will evaluate the security with a different segment that shares more similar risk characteristics.

    In estimating the net amount expected to be collected for mortgage-backed residential securities and municipal bonds, a range of historical losses method is utilized.  In estimating the net amount expected to be collected for TruPS, the Company employs a single scenario forecast methodology.  The scenario is informed by historical industry default data as well as current and near term operating conditions for the banks and other financial institutions that are the underlying issuers. In addition, prepayment assumptions are included in the analysis of the individually assessed TruPS applied at the collateral level.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures

     The Company is required to include the unfunded commitment that is expected to be funded in the future within the allowance calculation. The Company participates in lending that results in an off-balance sheet unfunded commitment balance. The Company currently underwrites funding commitments with conditionally cancelable language. To determine the expected funding balance remaining, the Company uses a historical utilization rate for each of the segments to calculate the expected commitment balance. The reserve percentage for each respective loan portfolio is applied to the remaining unused portion of the expected commitment balance and the expected funded commitment in determining the allowance for credit loss on off-balance sheet credit exposures.

Section 4013 of the CARES Act

    The Company implemented various consumer and commercial loan modification programs to provide its borrowers relief from the economic impacts of COVID-19. In accordance with the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), the Company elected to not apply troubled debt restructuring classification to any COVID-19 related loan modifications that occurred after March 1, 2020 to borrowers who were current as of December 31, 2019. Accordingly, these modifications are exempt from troubled debt restructuring classification under U.S. generally accepted accounting principles (“U.S. GAAP”) and were not classified as troubled debt restructurings (“TDRs”). In addition, for loans modified in response to the COVID-19 pandemic that did not meet the above criteria (e.g., current payment status at December 31, 2019), the Company applied the guidance included in an interagency statement issued by the bank regulatory agencies. This guidance states that loan modifications performed in light of the COVID-19 pandemic, including loan payment deferrals that are up to six months in duration, that were granted to borrowers who were current as of the implementation date of a loan modification program or modifications granted under government mandated modification programs, are not TDRs. For loan modifications that include a payment deferral and are not TDRs, the borrower’s past due and non-accrual status have not been impacted during the deferral period. The majority of our deferrals initially consisted of 90-day principal and interest deferrals with additional deferral periods granted on a case by case basis at the Bank’s option. Interest income has continued to be recognized over the contractual life of the loan. At September 30, 2020, loans with an aggregate outstanding balance of approximately $1.02 billion were in COVID-19 related deferment. For the nine months ended September 30, 2020, interest income on deferred loans totaled $44.3 million, of which $9.3 million was included in accrued interest receivable as of September 30, 2020.

2.     Stock Transactions

Stock Repurchase Program

    On October 25, 2018, the Company announced its fourth share repurchase program, which authorized the purchase of 10% of its publicly-held outstanding shares of common stock, or 28,886,780 shares. The fourth program commenced immediately upon completion of the third program on December 10, 2018 and remains the Company’s current program as of September 30, 2020.

8

    During the nine months ended September 30, 2020, the Company purchased 390,712 shares at a cost of $3.4 million, or $8.75 per share. All shares purchased during the nine months ended September 30, 2020 were purchased in connection with the vesting of shares of restricted stock under our 2015 Equity Incentive Plan and the withholding of shares to pay income taxes. These shares are repurchased pursuant to the terms of the 2015 Equity Incentive Plan and therefore are not part of the Company’s repurchase program.

3.     Business Combinations

Gold Coast Bancorp    

    As of the close of business on April 3, 2020, the Company completed its acquisition of Gold Coast Bancorp (“Gold Coast”) pursuant to the Agreement and Plan of Merger, dated as of July 24, 2019 by and between the Company and Gold Coast. As a result of the completion of the acquisition, the Company issued approximately 2.8 million shares to the former stockholders of Gold Coast and paid approximately $31.0 million in cash to the former stockholders of Gold Coast. Under the terms of the merger agreement, 50% of the common shares of Gold Coast were converted into Investors Bancorp common stock and the remaining 50% was exchanged for cash. For each share of Gold Coast Bancorp common stock, Gold Coast shareholders were given an option to receive either (i) 1.422 shares of Investors Bancorp common stock, $0.01 par value per share, (ii) a cash payment of $15.75, or (iii) a combination of Investors Bancorp common stock and cash. The foregoing was subject to proration to ensure that, in the aggregate, 50% of Gold Coast’s shares would be converted into Investors Bancorp common stock.

    The acquisition was accounted for under the acquisition method of accounting as prescribed by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805 “Business Combinations”, as amended. Under this method of accounting, the purchase price has been allocated to the respective assets acquired based on their estimated fair values, net of applicable income tax effects. The excess cost over fair value of assets acquired, or $12.0 million, has been recorded as goodwill.

    The acquired portfolio was fair valued on the date of acquisition based on guidance from ASC 820-10 which defines fair value as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. The valuation methods utilized took into consideration adjustments for interest rate risk, funding cost, servicing cost, residual risk, credit and liquidity risk.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition for Gold Coast, net of cash consideration paid:

	At April 3, 2020
	(In millions)
Cash and cash equivalents	$	7.3
Debt securities available-for-sale	51.5
Debt securities held to maturity	8.4
Loans receivable, net	443.5
Accrued interest receivable	1.3
Right-of-use assets	3.7
Net deferred tax asset	3.9
Intangible assets	14.5
Other assets	1.2
Total assets acquired	535.3
Deposits	489.9
Borrowed funds	14.9
Other liabilities	9.7
Total liabilities assumed	514.5
Net assets acquired	$	20.8

    As the Company finalizes its analysis of these assets, there may be adjustments to the recorded carrying values. Any adjustments to carrying values will be recorded in goodwill. The calculation of goodwill is subject to change for up to one year after closing date of the transaction as additional information relative to closing date estimates and uncertainties becomes available. For the three months ended September 30, 2020, there was no change to the amount of goodwill recorded for this acquisition.

    Financial assets acquired in a business combination after January 1, 2020 are recorded in accordance with ASC Topic 326, after which acquired assets are separated into two types. PCD assets are acquired assets that, as of the acquisition date, have experienced a more-than-insignificant deterioration in credit quality since origination. Non-PCD assets are acquired assets that have experienced no or insignificant deterioration in credit quality since origination. To distinguish between the two types of acquired assets, the Company evaluates risk characteristics that have been determined to be indicators of deteriorated credit quality. In the case of loans, the determining criteria may involve general characteristics, such as loan payment history or changes in creditworthiness since the loan was originated, while others are relevant to recent economic conditions, such as borrowers in industries impacted by the pandemic.

In its acquisition of Gold Coast, the Company has purchased loans which have been determined to be PCD. The carrying amount of those loans was as follows:

	At April 3, 2020
	(In millions)
Purchase price of loans at acquisition	$	244.7
Allowance for credit losses at acquisition	4.2
Non-credit discount (premium) at acquisition	2.6
Par value of acquired loans at acquisition	$	251.5

There were no PCD securities in the acquisition.

Fair Value Measurement of Assets Acquired and Liabilities Assumed

    Described below are the methods used to determine the fair values of the significant assets acquired and liabilities assumed in the Gold Coast acquisition based on guidance from ASC 820-10 which defines fair value as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date.

Securities. The securities acquired are bought and sold in active markets. The estimated fair values of securities were calculated using external third party broker opinions of the market values. Due to the instability of the market at the time of acquisition as well as the odd lot position sizes of the securities, the Company reviewed the data and assumptions used in pricing the securities by third-parties and made qualitative adjustments to reflect the odd lot size of the securities and the price that would be received in an orderly transaction.

Loans. The estimated fair values of the loan portfolio generally consider adjustments for interest rate risk, required funding costs, servicing costs, prepayments, credit and liquidity. Level 3 inputs were utilized to determine the fair value of the acquired loan portfolio and included the use of present value techniques employing cash flow estimates and incorporated assumptions that market participants would use in estimating fair values. In instances where reliable market information was not available, the Company used its own assumptions in an effort to determine fair value. The primary approach to determining the fair value of the loan portfolio was a discounted cash flow methodology that considered factors including the type of loan, underlying collateral, classification status or grade, interest rate structure (fixed or variable interest rate), and remaining term. For the non-credit component, loans were grouped together according to similar characteristics when applying the various valuations techniques. For the credit component, loans were also grouped based on whether they had more than insignificant deterioration in credit since origination (purchase credit deteriorated “PCD” as defined by ASC 326-20). The expected life of loan loss estimates were calculated based on an annual loss rate developed by using the historical annual average charge-off percentages for New York institutions as a proxy for how a market participant acquirer would value the portfolio. Additionally, a qualitative credit adjustment was applied to the historical annual loss rates, due to COVID-19 and the uncertainty of future losses.

Deposits / Core Deposit Intangible. The core deposit intangible represents the value assigned to the stable and below market rate funding sources within the acquired deposit base; typically demand deposits, interest checking, money market and savings accounts. The core deposit intangible value represents the value of the relationships with deposit customers as a below market rate funding source. The fair value was based on a discounted cash flow methodology that gave appropriate consideration to expected deposit attrition rates, net maintenance costs of the deposit base, projected interest costs and the alternative cost of funds. Certificates of deposit (time deposits) are not considered to be core deposits as they are less stable and do not have an “all-in” favorable funding advantage to the alternative cost of funds. The fair value of certificates of deposit represents the present value of the certificates’ expected contractual payments discounted by market rates for similar certificates and is determined utilizing Level 2 inputs.

10

Borrowed Funds. A discounted cash flow approach was used to determine the fair value of the debt acquired. The fair value of the liability represents the present value of the expected payments discounted using a risk adjusted discount rate. The discount rate was developed based on comparable rated securities, as that backed by companies with similar credit ratings as the Company.

5.     Securities

Equity Securities

    Equity securities are reported at fair value on the Company’s Consolidated Balance Sheets. The Company’s portfolio of equity securities had an estimated fair value of $8.7 million and $6.0 million as of September 30, 2020 and December 31, 2019, respectively. Realized gains and losses from sales of equity securities as well as changes in fair value of equity securities still held at the reporting date are recognized in the Consolidated Statements of Income.

(1) Net unrealized losses of held-to-maturity corporate and other debt securities represent the previously recorded other than temporary charge related to other non-credit factors and is being amortized through accumulated other comprehensive income over the remaining life of the securities. For mortgage-backed securities, it represents the net loss on previously designated available-for sale debt securities transferred to held-to-maturity at fair value and is being amortized through accumulated other comprehensive income over the remaining life of the securities.

(2) Unrecognized gains and losses of held-to-maturity debt securities are not reflected in the financial statements, as they represent fair value fluctuations from the later of: (i) the date a security is designated as held-to-maturity; or (ii) the date that an other than temporary impairment charge is recognized on a held-to-maturity security, through the date of the balance sheet. Effective January 1, 2020, held-to-maturity debt securities are evaluated for credit losses to determine if an allowance is necessary. Any allowance required is recorded through the provision for credit losses.

    We conduct periodic reviews of individual securities to assess whether an allowance for credit loss is required. Held-to-maturity debt securities are evaluated for expected credit loss utilizing a historical loss methodology, or a discounted cash flows approach which is assessed against the book value of the investment security excluding accrued interest. Refer to Note 1, Summary of Significant Accounting Principles, for additional information. Available-for-sale debt securities are evaluated to determine if a decline in fair value below the amortized cost basis has resulted from a credit loss or other factors. An impairment related to credit factors would be recorded through an allowance for credit losses. The allowance is limited to the amount by which the security’s amortized cost basis exceeds the fair value. An impairment that has not been recorded through an allowance for credit losses shall be recorded through other comprehensive income, net of applicable taxes. Investment securities will be written down to fair value through the consolidated statement of income when management intends to sell (or may be required to sell) the securities before they recover in value.

    The majority of our held-to-maturity debt securities portfolio is comprised of agency mortgage-backed securities. For agency (FNMA, FHLMC and GNMA) mortgage-backed securities, and other agency debt instruments, the expectation of non-payment is zero. The timely payment of principal and interest on FNMA and FHLMC securities is guaranteed by each corporation. As each of these corporations is in conservatorship with the federal government, the payment guarantees are considered implicit obligations of the US government. GNMA securities carry the full faith and credit guarantee of the federal government. Because of the existence of government guarantees of timely payment of principal and interest, expected losses on agency securities are assumed to be zero. Changes in the fair value of agency securities in this portfolio are primarily driven by changes in interest rates and other non-credit related factors. At September 30, 2020, our held-to-maturity debt securities portfolio had an allowance for credit losses of $3.1 million. The allowance is related to non-agency corporate and other debt securities. The majority of the allowance is related to a portfolio of collateralized debt obligations backed by pooled TruPS, principally issued by banks and to a lesser extent insurance companies and real estate investment trusts. At September 30, 2020, the TruPS had a carrying value before allowance for credit losses and estimated fair value of $49.3 million and $64.1 million, respectively. The Company does not have the intent to sell these securities and does not believe it is more likely than not that the Company will be required to sell these securities before a recovery of amortized cost.

    At September 30, 2020, the available-for-sale debt securities portfolio was almost entirely comprised of agency securities. As such, the unrealized losses in this portfolio are primarily driven by changes in interest rates and other non-credit related factors. The Company does not have the intent to sell these securities and does not believe it is more likely than not that the Company will be required to sell these securities before a recovery of amortized cost. As of September 30, 2020, there is no allowance for credit losses related to the Company’s available-for-sale debt securities as the decline in fair value did not result from credit issues.

    For additional information about the review of securities under previous other-than-temporary impairment guidance, refer to page 82 in Note 4 to the consolidated financial statements included under Item 15. Exhibits and Financial Statement Schedules in the Company’s December 31, 2019 Form 10-K.

    Debt securities with a carrying value before allowance for credit losses of $1.57 billion and an estimated fair value of $1.62 billion are pledged to secure borrowings and municipal deposits. The contractual maturities of the Bank’s mortgage-backed securities are generally less than 20 years with effective lives expected to be shorter due to prepayments. Expected maturities may differ from contractual maturities due to underlying loan prepayments or early call privileges of the issuer; therefore, mortgage-backed securities are not included in the following table. Excluding the allowance for credit losses, the amortized cost and estimated fair value of debt securities other than mortgage-backed securities at September 30, 2020, by contractual maturity, are shown below.

2020, the Company received proceeds of $16.5 million from the call of a held-to-maturity debt security which resulted in a gain of $124,000 and received a principal payment of $26,000 on a held-to-maturity debt security. The Company recognized net unrealized losses on equity securities of $8,000 and net unrealized gains of $99,000, respectively, for the three and nine months ended September 30, 2020.

    For the three months ended September 30, 2019, there were no sales of securities. For the nine months ended September 30, 2019, the Company received proceeds of $399.4 million on securities sold from the debt securities available-for-sale portfolio resulting in a loss of $5.7 million recognized in non-interest income. Proceeds from the sale were reinvested in higher yielding debt securities. There were no other sales of securities for the nine months ended September 30, 2019. The Company recognized net unrealized gains on equity securities of $30,000 and $165,000, respectively, for the three and nine months ended September 30, 2019.

Credit Quality Indicators

    The Company has lending policies and procedures that provide target market, underwriting and other criteria for identified lending segments to codify the level of credit risk the Company is willing to accept. Approval authority levels are delegated to qualified individuals and approval bodies for the extension of credit within the guidance of these policies and procedures. In addition, the Company maintains an independent loan review department that reviews and validates risk assessment on a continual basis.

    The Company assigns ratings to borrowers and transactions based on the assessment of a borrower’s ability to service their debt based on relevant information such as: current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors.

    In connection with the adoption of Topic 326 on January 1, 2020, the Company implemented new risk rating models for borrowers and transactions within its commercial loan portfolio. The risk rating methodology transitioned to a dual risk rating framework which bifurcates ratings into probability of default (PD) and loss given default (LGD). Relevant risks are evaluated prior to approving a transaction to determine if the transaction is within the Company’s risk appetite and the appropriate rating. Strong credit analysis requires current, reliable financial information and documented assessment of the customer’s:

•ability to perform in accordance with the terms of the credit, including adherence to covenants;

•assets and liabilities, liquidity, net worth, and contingent and other off-balance sheet items;

•tax liabilities;

•cash reserves and ability to convert assets to cash;

•income statement and the sources, level, stability, and quality of earnings:

17

•projected performance, sensitized for stressed circumstances; and

•industry performance relative to peers and industry.

    Each commercial credit facility is assigned a PD and LGD rating for the purpose of informing a credit decision, facilitating the determination of the expected level of credit loss and other portfolio management activities (as well as relationship profitability). The dual risk rating framework and risk rating methodologies allow for consistent determination of risk across the Commercial business as indicated by the risk rating assigned. The methodology used by the Bank applies the same criteria for identification of a credit as for the regulatory definitions of risk ratings:

Pass - “Pass” assets are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell, of any underlying collateral in a timely manner.

Watch - A “Watch” asset has all the characteristics of a Pass asset but warrants more than the normal level of supervision. These loans may require more detailed reporting to management because some aspects of underwriting may not conform to policy or adverse events may have affected or could affect the cash flow or ability to continue operating profitably, provided, however, the events do not constitute an undue credit risk. Residential and consumer loans delinquent 30-59 days are considered watch if not a troubled debt restructuring (“TDR”). In addition, any residential or consumer loan currently on deferment in accordance with the CARES Act or the interagency statement issued by bank regulatory agencies are considered watch.

Special Mention - A “Special Mention” asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. Residential and consumer loans delinquent 60-89 days are considered special mention if not a TDR.

Substandard - A “Substandard” asset is inadequately protected by the current worth and paying capacity of the obligor or by the collateral pledged, if any. Assets so classified must have a well-defined weakness, or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Residential and consumer loans delinquent 90 days or greater as well as TDRs are considered substandard.

Doubtful - An asset classified “Doubtful” has all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently known facts, conditions, and values.

Loss - An asset or portion thereof, classified “Loss” is considered uncollectible and of such little value that its continuance on the institution’s books as an asset, without establishment of a specific valuation allowance or charge-off, is not warranted. This classification does not necessarily mean that an asset has no recovery or salvage value; but rather, there is much doubt about whether, how much, or when the recovery will occur. As such, it is not practical or desirable to defer the write-off.

Delinquent and Non-Accrual Loans

In the absence of other intervening factors, loans granted payment deferrals related to COVID-19 are not reported as past due or placed on non-accrual status provided the borrowers have met the criteria in the CARES Act or otherwise have met the criteria included in an interagency statement issued by bank regulatory agencies. See Note 1, Summary of Significant Accounting Principles.

Individually Evaluated Loans

    Loans which do not share common risk characteristics with other loans are individually evaluated as part of the process of calculating the allowance for credit losses. The evaluation is determined on an individual basis using the present value of expected cash flows or the fair value of the collateral as of the reporting date. When management determines that the fair value of collateral securing a collateral dependent loan inadequately covers the balance of net principal, the net principal balance is written down to the fair value of the collateral, net of estimated selling costs as applicable, rather than assigning an allowance. See Note 16, Fair Value Measurements, for information regarding the valuation process for collateral dependent loans.

The following table presents individually evaluated collateral-dependent loans by class of loans at the date indicated:

TDR Loans Included in Non-Accrual

Included in the non-accrual tables above are TDR loans whose payment status is current, but the Company has classified as non-accrual as the loans have not maintained their current payment status for six consecutive months under the restructured terms and therefore do not meet the criteria for accrual status. As of September 30, 2020 and December 31, 2019, these loans are comprised of the following:

	September 30, 2020			December 31, 2019
	# of loans	Amount		# of loans	Amount
	(Dollars in thousands)
TDR with payment status current classified as non-accrual:

Total TDR 30-89 days delinquent classified as non-accrual	9	$	1,296	18	$	3,331

    The Company has no loans past due 90 days or more delinquent that are still accruing interest.

Troubled Debt Restructurings    

    On a case-by-case basis, the Company may agree to modify the contractual terms of a borrower’s loan to remain competitive and assist customers who may be experiencing financial difficulty, as well as preserve the Company’s position in the loan. If the borrower is experiencing financial difficulties and a concession has been made at the time of such modification, the loan is classified as a TDR.

    Substantially all of our TDR loan modifications involve lowering 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, or a combination of these two methods. These modifications rarely result in the forgiveness of principal or accrued interest. In addition, we frequently obtain additional collateral or guarantor support when modifying commercial loans. Restructured loans remain on non-accrual status until there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible.

    Consistent with the CARES Act and interagency guidance which allows temporary relief for current borrowers affected by COVID-19, we are working with borrowers and granting certain modifications through programs related to

22

COVID-19 relief. At September 30, 2020, loans with an aggregate outstanding balance of approximately $1.02 billion have been granted modifications as a result of financial disruptions associated with the COVID-19 pandemic. Also, consistent with the CARES Act and the interagency guidelines, such modifications that met the criteria discussed in Note 1 are not included in our TDR totals and discussion below. For more information on the criteria for classifying loans as TDRs, see Note 1, Summary of Significant Accounting Principles - Section 4013 of the CARES Act.

The following tables present the total TDR loans at September 30, 2020 and December 31, 2019:

    Post-modification recorded investment represents the net book balance immediately following modification.

    Collateral dependent loans classified as TDRs were written down to the estimated fair value of the collateral. There were no charge offs for TDRs during the three months ended September 30, 2020. There were $163,000 in charge-offs for a TDR of an unsecured commercial and industrial loan during the nine months ended September 30, 2020. There were $156,000 and $729,000 in charge-offs for TDRs of unsecured commercial and industrial loans during the three and nine months ended September 30, 2019, respectively. The allowance for loan losses associated with the TDRs presented in the above tables totaled $1.6 million and $1.8 million as of September 30, 2020 and December 31, 2019, respectively.

    Loan modifications generally involve the reduction in loan interest rate and/or extension of loan maturity dates and also may include step up interest rates in their modified terms which will impact their weighted average yield in the future. Prior to 2020, all residential loans deemed to be TDRs were modified to reflect a reduction in interest rates to current market rates. Residential loans modified in 2020 and deemed to be TDRs were granted a payment deferral related to COVID-19 but did not meet the criteria to be excluded from TDR as described in Note 1, Summary of Significant Accounting Principles - Section 4013 of the CARES Act. Two of the commercial loan modifications which qualified as a TDR in the nine months ended September 30, 2020 were loans which had already been on non-accrual status and were granted a deferral of payment due to circumstances related to COVID-19. Another commercial loan modification which qualified as a TDR in the first quarter of 2020 had its maturity extended. The commercial loan modifications which qualified as TDRs in the nine months ended September 30, 2019 had their maturity extended.

    The following tables present information about pre and post modification interest yield for TDRs which occurred during the three and nine months ended September 30, 2020 and 2019:

7.    Allowance for Credit Losses

    On January 1, 2020, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the CECL methodology. See Note 1, Summary of Significant Accounting Principles.

An analysis of the provision for credit losses is summarized as follows:

	Three Months Ended September 30,			Nine Months Ended September 30,
	2020		2019	2020	2019
	(In thousands)
Provision for loan losses	$	14,859	(2,500)	71,535	(2,500)

    Accrued interest receivable on loans, reported as a component of accrued interest receivable on the balance sheet, totaled $74.3 million at September 30, 2020. For the period ended September 30, 2020, the Company recorded a provision for loan loss related to interest accrued on residential and consumer loans in payment deferral.

    The lifetime estimate considers multiple economic scenarios, including recessionary scenarios that assume deterioration in key economic variables such as gross domestic product, unemployment rate and real estate prices.  As of January 1, 2020, the Company’s economic outlook was weighted to include a moderate potential of a recession with some expectation of tail risk similar to the severely adverse scenario used in stress testing. During the nine months ended September 30, 2020, there was a significant change in the economic outlook impacting the allowance for credit losses, with key economic factors such as the unemployment rate and gross domestic product severely affected by the impact of COVID-19. For the three months ended September 30, 2020, there was improvement in the U.S. and global macroeconomic consensus outlooks, which resulted in an improvement in the economic outlook used to determine the allowance for credit losses when compared to June 30, 2020. In response to these changes, the Company continues to assess the selection and probability weightings of the economic scenarios.  Multiple economic outlooks were used for the September 30, 2020 estimate of the allowance for credit losses that included a base or consensus case, a downside recessionary case and an upside scenario to reflect the potential for continued improvement in the economic outlook.  In addition, the allowance for credit losses at September 30, 2020 included qualitative reserves for certain segments that may not be fully recognized through its quantitative models.  There are still many unknowns including the duration of the impact of COVID-19 on the economy and the results of the government fiscal and monetary actions along with recently implemented payment deferral programs, and the Company will continue to evaluate the allowance for credit losses and the related economic outlook each quarter.

The following table summarizes other intangible assets as of September 30, 2020 and December 31, 2019:

	Gross Intangible Asset		Accumulated Amortization	Valuation Allowance	Net Intangible Assets
	(In thousands)
September 30, 2020
Mortgage servicing rights	$	18,004	(5,570)	(1,458)	10,976
Core deposit premiums	23,063		(19,109)	—	3,954

Other	1,150		(482)	—	668
Total other intangible assets	$	41,079	(25,653)	(103)	15,323

    Mortgage servicing rights are accounted for using the amortization method. Under this method, the Company amortizes the loan servicing asset in proportion to, and over the period of, estimated net servicing revenues. The Company sells loans on a servicing-retained basis. Loans that were sold on this basis had an unpaid principal balance of $1.74 billion and $1.67 billion at September 30, 2020 and December 31, 2019, respectively, all of which relate to mortgage loans. At September 30, 2020 and December 31, 2019, the servicing asset, included in other intangible assets, had an estimated fair value of $11.2 million and $14.1 million, respectively. At September 30, 2020, fair value was based on expected future cash flows considering a weighted average discount rate of 12.03%, a weighted average constant prepayment rate on mortgages of 19.14%

29

and a weighted average life of 4.2 years. Based on an analysis of fair values as of September 30, 2020, the Company determined that a $1.5 million valuation allowance for mortgage servicing rights was required, a decrease of $1.2 million from the previous quarter. See Note 16 for additional details.

    Core deposit premiums are amortized using an accelerated method and having a weighted average amortization period of 10 years. For the nine months ended September 30, 2020, the Company recorded $2.5 million in core deposit premiums resulting from the acquisition of Gold Coast.

10.     Leases

    The Company has operating leases for corporate offices, branch locations and certain equipment. For these operating leases, the Company recognizes 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. The Company’s leases have remaining lease terms of up to 16 years, some of which include options to extend the leases for up to 10 years, and some of which include options to terminate the leases within 1 year. Certain of our operating leases for branch locations contain variable lease payments related to consumer price index adjustments.

The following table presents the balance sheet information related to our operating leases:

	September 30, 2020			December 31, 2019
	(Dollars in thousands)
Operating lease right-of-use assets	$	171,781		175,143
Operating lease liabilities	184,281			185,827
Weighted average remaining lease term	9.0 years			9.7 years
Weighted average discount rate	2.66		%	2.74	%

    In determining the present value of lease payments, the discount rate used for each individual lease is the rate implicit in the lease, unless that rate cannot be readily determined, in which case the Company is required to use its incremental borrowing rate based on the information available at commencement date. For its incremental borrowing rate, the Company uses the borrowing rates offered to the Company by the Federal Home Loan Bank, which reflects the rates a lender would charge the Company to obtain a collateralized loan.

The following table presents the components of total operating lease cost recognized in the Consolidated Statements of Income:

	Three Months Ended September 30,			Nine Months Ended September 30,
	2020		2019	2020	2019

    The Company also has finance leases for certain equipment. The Company’s right-of-use assets and lease liabilities for finance leases were $2.7 million and $2.8 million, respectively, at September 30, 2020. The finance lease right-of-use assets and finance lease liabilities are included within Other assets and Other liabilities, respectively, on the Consolidated Balance Sheet.

11.     Equity Incentive Plan

    At the annual meeting held on June 9, 2015, stockholders of the Company approved the Investors Bancorp, Inc. 2015 Equity Incentive Plan (“2015 Plan”) which provides for the issuance or delivery of up to 30,881,296 shares (13,234,841 restricted stock awards and 17,646,455 stock options) of Investors Bancorp, Inc. common stock.

    Restricted shares granted under the 2015 Plan vest in equal installments, over the service period generally ranging from 5 to 7 years beginning one year from the date of grant. Additionally, certain restricted shares awarded are performance vesting awards, which may or may not vest depending upon the attainment of certain corporate financial targets. The vesting of restricted stock may accelerate in accordance with the terms of the 2015 Plan. The product of the number of shares granted and the grant date closing market price of the Company’s common stock determine the fair value of restricted shares under the 2015 Plan. Management recognizes compensation expense for the fair value of restricted shares on a straight-line basis over the requisite service period. For the nine months ended September 30, 2020 and September 30, 2019, the Company granted 90,067 and 2,345,919 shares of restricted stock awards under the 2015 Plan, respectively.

    Stock options granted under the 2015 Plan vest in equal installments, over the service period generally ranging from 5 to 7 years beginning one year from the date of grant. The vesting of stock options may accelerate in accordance with the terms of the 2015 Plan. Stock options were granted at an exercise price equal to the fair value of the Company’s common stock on the grant date based on the closing market price and have an expiration period of 10 years. For the nine months ended September 30, 2020 and September 30, 2019, the Company granted no stock options and 995,216 stock options under the 2015 Plan, respectively.

    The fair value of stock options granted as part of the 2015 Plan was estimated utilizing the Black-Scholes option pricing model using the following assumptions for the periods presented below:

	Nine Months Ended September 30,
	2019
Weighted average expected life (in years)	4.83
Weighted average risk-free rate of return	1.86		%
Weighted average volatility	19.92		%
Dividend yield	3.96		%
Weighted average fair value of options granted	$	0.89
Total stock options granted	995,216

    The weighted average expected life of the stock option represents the period of time that stock options are expected to be outstanding and is estimated using historical data of stock option exercises and forfeitures. The risk-free interest rate is

31

based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility is based on the historical volatility of the Company’s stock. The Company recognizes compensation expense for the fair values of these awards, which have graded vesting, on a straight-line basis over the requisite service period of the awards. Upon exercise of vested options, management expects to draw on treasury stock as the source for shares.

    The following table presents the share-based compensation expense for the three and nine months ended September 30, 2020 and 2019:

	Three Months Ended September 30,			Nine Months Ended September 30,
	2020		2019	2020	2019
	(In thousands)
Stock option expense	$	941	2,285	2,940	4,937
Restricted stock expense	2,539		4,026	8,383	10,933
Total share-based compensation expense (1)	$	3,480	6,311	11,323	15,870

(1) Included in share-based compensation expense for the three months and nine months ended September 30, 2019 was $2.0 million of accelerated stock compensation expense resulting from the settlement of shareholder litigation during the third quarter of 2019. There was no incremental expense resulting from the modification of the original awards associated with the settlement. For additional information about the settlement, refer to page 105 in Note 12 to the consolidated financial statements included under Item 15. Exhibits and Financial Statement Schedules in the Company’s December 31, 2019 Form 10-K.

    The following is a summary of the Company’s stock option activity and related information for the nine months ended September 30, 2020:

	Number of Stock Options	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in years)	Aggregate Intrinsic Value
Outstanding at December 31, 2019	5,654,461	$	12.46	5.5	$	363

Exercisable at September 30, 2020	3,810,659	$	12.42	4.7	$	—

    Expected future expense relating to the non-vested options outstanding as of September 30, 2020 is $6.5 million over a weighted average period of 1.45 years.

    The following is a summary of the status of the Company’s restricted shares as of September 30, 2020 and changes therein during the nine months ended:

	Number of Shares Awarded	Weighted Average Grant Date Fair Value
Outstanding at December 31, 2019	2,894,352	$	12.57

    Expected future expense relating to the non-vested restricted shares outstanding as of September 30, 2020 is $20.1 million over a weighted average period of 2.28 years.

12.     Net Periodic Benefit Plan Expense

    The Company has an Executive Supplemental Retirement Wage Replacement Plan (“SERP II”) and the Supplemental ESOP and Retirement Plan (“SERP I”) (collectively, the “SERPs”). The SERP II is a nonqualified, defined benefit plan which provides benefits to certain executives as designated by the Compensation and Benefits Committee of the Board of Directors. More specifically, the SERP II was designed to provide participants with a normal retirement benefit equal to an annual benefit of 60% of the participant’s highest annual base salary and cash incentive (over a consecutive 36-month period within the

32

participant’s credited service period) reduced by the sum of the benefits provided under the Pentegra Defined Benefit Plan for Financial Institutions (“Pentegra DB Plan”) and the SERP I. Effective as of the close of business of December 31, 2016, the SERP II was amended to freeze future benefit accruals subsequent to the 2016 year of service.

    The SERP I compensates certain executives (as designated by the Compensation and Benefits Committee of the Board of Directors) participating in the ESOP whose contributions are limited by the Internal Revenue Code. The Company also maintains the Amended and Restated Director Retirement Plan (“Directors’ Plan”) for certain directors, which is a nonqualified, defined benefit plan. The Directors’ Plan was frozen on November 21, 2006 such that no new benefits accrued under, and no new directors were eligible to participate in the plan. The SERPs and the Directors’ Plan are unfunded and the costs of the plans are recognized over the period that services are provided.

The components of net periodic benefit cost for the Directors’ Plan and the SERP II are as follows:

	Three Months Ended September 30,			Nine Months Ended September 30,
	2020		2019	2020	2019
	(In thousands)
Interest cost	$	325	397	973	1,191
Amortization of:
Net loss	298		—	896	—
Total net periodic benefit cost	$	623	397	1,869	1,191

    Due to the unfunded nature of the SERPs and the Directors’ Plan, no contributions have been made or were expected to be made during the nine months ended September 30, 2020.

    The Company also maintains the Pentegra DB Plan. As of December 31, 2016, the annual benefit provided under the Pentegra DB plan was frozen by an amendment to the plan. Freezing the plan eliminates all future benefit accruals and each participant’s frozen accrued benefit was determined as of December 31, 2016 and no further benefits will accrue beyond such date. Since it is a multi-employer plan, costs of the pension plan are based on contributions required to be made to the pension plan. There was no contribution required during the nine months ended September 30, 2020. We anticipate contributing funds to the plan to meet any minimum funding requirements for the remainder of 2020.

13.    Derivatives and Hedging Activities

    The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s floating rate borrowings and pools of fixed-rate assets.

Cash Flow Hedges of Interest Rate Risk

    The Company’s objectives in using interest rate derivatives are primarily to reduce cost and add stability to interest expense in an effort to manage its exposure to interest rate movements. Interest rate swaps designated as cash flow hedges involve the receipt of amounts subject to variability caused by changes in interest rates from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.  Changes in the fair value of derivatives designated and that qualify as cash flow hedges are initially recorded in other comprehensive income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Such derivatives were used to hedge the variability in cash flows associated with borrowings. The Company is hedging its exposure to the variability in future cash flows for forecasted transactions over a maximum period of fourteen months (excluding forecasted transactions related to the payment of variable interest on existing financial instruments).

    Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate borrowings. During the next twelve months, the Company estimates that an additional $46.7 million will be reclassified as an increase to interest expense.

33

Fair Value Hedges of Interest Rate Risk

    The Company is exposed to changes in the fair value of certain of its pools of fixed-rate assets due to changes in benchmark interest rates. The Company may use interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate. Interest rate swaps designated as fair value hedges involve the payment of fixed-rate amounts to a counterparty in exchange for the Company receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. Such derivatives were used to hedge the changes in fair value of certain of its pools of prepayable fixed-rate assets.

    For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in interest income.

    The Company terminated two interest rate swaps with an aggregate notional of $475.0 million during the nine months ended September 30, 2020. The Company terminated three interest rate swaps with an aggregate notional amount of $1.00 billion during the year ended December 31, 2019. The terminated swaps were due to mature in February 2020. There were no interest rate swaps designated as fair value hedges as of September 30, 2020.

Derivatives Not Designated as Hedges

    The Company has credit derivatives resulting from participation in interest rate swaps provided to external lenders as part of loan participation arrangements which are, therefore, not used to manage interest rate risk in the Company’s assets or liabilities. Additionally, the Company provides interest rate risk management services to commercial customers, primarily interest rate swaps. The Company’s market risk from unfavorable movements in interest rates related to these derivative contracts is economically hedged by concurrently entering into offsetting derivative contracts that have identical notional values, terms and indices.

    Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain lenders which participate in loans and commercial customers.

16.    Fair Value Measurements

    We use fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Our debt securities available-for-sale and derivatives are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record at fair value other assets or liabilities on a non-recurring basis, such as held-to-maturity debt securities, mortgage servicing rights (“MSR”), loans receivable and other real estate owned. These non-recurring fair value adjustments involve the application of lower-of-cost-or-market accounting or write-downs of individual assets. Additionally, in connection with our mortgage banking activities we have commitments to fund loans held-for-sale and commitments to sell loans, which are considered free-standing derivative instruments, the fair values of which are not material to our financial condition or results of operations.

    In accordance with FASB ASC 820, “Fair Value Measurements and Disclosures”, we group our assets and liabilities at fair value in three levels, based on the markets in which the assets are traded and the reliability of the assumptions used to determine fair value. These levels are:

•Level 1 – Valuation is based upon quoted prices for identical instruments traded in active markets.

•Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market.

38

•Level 3 – Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include the use of option pricing models, discounted cash flow models and similar techniques. The results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset or liability.

    We base our fair values on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

Assets Measured at Fair Value on a Recurring Basis

Equity securities

    Our equity securities portfolio is carried at estimated fair value on a recurring basis, with any unrealized gains and losses recognized in the Consolidated Statements of Income. The fair values of equity securities are based on quoted market prices (Level 1).

Debt securities available-for-sale

    Our debt securities available-for-sale portfolio is carried at estimated fair value on a recurring basis, with any unrealized gains and losses, net of taxes, reported as accumulated other comprehensive income (loss) in stockholders’ equity. The fair values of debt securities available-for-sale are based upon quoted prices for similar instruments in active markets (Level 2). The pricing service may use quoted market prices of comparable instruments or discounted cash flow analyses, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in the valuation methodologies include, but are not limited to, benchmark yields, credit spreads, default rates, prepayment speeds and non-binding broker quotes. As the Company is responsible for the determination of fair value, it performs quarterly analyses 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 test 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 adjustment in the prices obtained from the pricing service.

39

Derivatives

    Derivatives are reported at fair value utilizing Level 2 inputs. The fair values of interest rate swap and risk participation agreements are based on a valuation model that uses primarily observable inputs, such as benchmark yield curves and interest rate spreads.

    The following tables provide the level of valuation assumptions used to determine the carrying value of our assets and liabilities measured at fair value on a recurring basis at September 30, 2020 and December 31, 2019.

Assets Measured at Fair Value on a Non-Recurring Basis

Mortgage Servicing Rights, Net

    Mortgage servicing rights are carried at the lower of cost or estimated fair value. The estimated fair value of MSR is obtained through independent third-party valuations through an analysis of future cash flows, incorporating assumptions market participants would use in determining fair value including market discount rates, prepayment 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.  At September 30, 2020, the fair value model used prepayment speeds ranging from 14.88% to 32.40% and a discount rate of 12.03% for the valuation of the mortgage servicing rights. At December 31, 2019, the fair value model used prepayment speeds ranging from 6.60% to 29.10% and a discount rate of 12.05% for the valuation of the mortgage servicing rights. 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 positive or negative effect on the fair value estimate.

Collateral-Dependent Loans/Impaired Loans Receivable

    With the adoption of ASU 2016-13, loans which meet certain criteria are individually evaluated as part of the process of calculating the allowance for credit losses. Prior to adoption, such loans were evaluated for impairment. However, the valuation method remains unchanged. A loan is individually evaluated when it is a commercial loan with an outstanding balance greater than $1.0 million and on non-accrual status, loans modified in a troubled debt restructuring, and other commercial loans with $1.0 million in outstanding principal if management has specific information that it is probable they will not collect all amounts due under the contractual terms of the loan agreement. Collateral-dependent loans secured by property are carried at the estimated fair value of the collateral less estimated selling costs. Estimated fair value is calculated using an independent third-party appraiser. In the event the most recent appraisal does not reflect the current market conditions due to the passage of time and other factors, management will obtain an updated appraisal or make downward adjustments to the existing appraised value based on their knowledge of the property, local real estate market conditions, recent real estate transactions, and for estimated selling costs, if applicable. Appraisals were generally discounted in a range of 0% to 25%. For non-collateral-dependent loans management estimates the fair value using discounted cash flows based on inputs that are largely unobservable and instead reflect management’s own estimates of the assumptions as a market participant would in pricing such loans.

Other Real Estate Owned and Other Repossessed Assets

    Other Real Estate Owned and Other Repossessed Assets are recorded at estimated fair value, less estimated selling costs when acquired, thus establishing a new cost basis. Fair value of foreclosed real estate property is generally based on independent appraisals. These appraisals include adjustments to comparable assets based on the appraisers’ market knowledge and experience and are discounted an additional 0% to 25% for estimated costs to sell. When an asset is acquired, the excess of the loan balance over fair value, less estimated selling costs, is charged to the allowance for loan losses. If further declines in the estimated fair value of the asset occur, a writedown is recorded through expense. The valuation of foreclosed and repossessed assets is subjective in nature and may be adjusted in the future because of changes in economic conditions. Operating costs after acquisition are generally expensed.

Loans Held for Sale

    Residential mortgage loans held for sale are recorded at the lower of cost or fair value and are therefore measured at fair value on a non-recurring basis. When available, the Company uses observable secondary market data, including pricing on recent closed market transactions for loans with similar characteristics.

    The following tables provide the level of valuation assumptions used to determine the carrying value of our assets measured at fair value on a non-recurring basis at September 30, 2020 and December 31, 2019. For the three months ended September 30, 2020, there was no change to the carrying value of collateral-dependent loans, other real estate owned or loans held for sale. For the three months ended December 31, 2019, there was no change to the carrying value of impaired loans or loans held for sale.

Other Fair Value Disclosures

    Fair value estimates, methods and assumptions for the Company’s financial instruments not recorded at fair value on a recurring or non-recurring basis are set forth below.

Cash and Cash Equivalents

    For cash, short-term U.S. Treasury securities and due from banks, the carrying amount approximates fair value.

Debt Securities Held-to-Maturity

    Our debt securities held-to-maturity portfolio, consisting primarily of mortgage-backed securities and other debt securities for which we have a positive intent and ability to hold to maturity, is carried at amortized cost less any allowance for credit losses. Management utilizes various inputs to determine the fair value of the portfolio. The Company obtains one price for each security primarily from a third-party pricing service, which generally uses quoted or other observable inputs for the determination of fair value. The pricing service normally derives the security prices through recently reported trades for identical or similar securities, making adjustments through the reporting date based upon available observable market information. For securities not actively traded, the pricing service may use quoted market prices of comparable instruments or discounted cash flow analyses, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in the valuation methodologies include, but are not limited to, benchmark yields, credit spreads, default rates, prepayment speeds and non-binding broker quotes. In the absence of quoted prices and in an illiquid market, valuation techniques, which require inputs that are both significant to the fair value measurement and unobservable, are used to determine fair value of the investment. Valuation techniques are based on various assumptions, including, but not limited to forecasted cash flows, discount rates, rate of return, adjustments for nonperformance and liquidity, and liquidation values. As the Company is responsible for the determination of fair value, it performs quarterly analyses 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 test 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 adjustment in the prices obtained from the pricing service.

42

FHLB Stock

    The fair value of the Federal Home Loan Bank of New York (“FHLB”) stock is its carrying value, since this is the amount for which it could be redeemed. There is no active market for this stock and the Bank is required to hold a minimum investment based upon the balance of mortgage related assets held by the member and or FHLB advances outstanding.

Loans

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

    The fair value estimates are made at a specific point in time based on relevant market information. They do not reflect any premium or discount that could result from offering for sale a particular financial instrument. Fair value estimates are based on judgments regarding future expected loss experience, risk characteristics and economic conditions. These estimates are subjective, involve uncertainties, and cannot be determined with precision.

Deposit Liabilities

    The fair value of deposits with no stated maturity, such as savings, checking accounts and money market accounts, is equal to the amount payable on demand. The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates which approximate currently offered for deposits of similar remaining maturities.

Borrowings

    The fair value of borrowings are based on securities dealers’ estimated fair values, when available, or estimated using discounted contractual cash flows using rates which approximate the rates offered for borrowings of similar remaining maturities.

43

Commitments to Extend Credit

    The fair value of commitments to extend credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For commitments to originate fixed rate loans, fair value also considers the difference between current levels of interest rates and the committed rates. Due to the short-term nature of our outstanding commitments, the fair values of these commitments are immaterial to our financial condition.

The carrying values and estimated fair values of the Company’s financial instruments are presented in the following table.

Limitations

    Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience,

44

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 that are not considered financial assets include deferred tax assets, premises and equipment and bank owned life insurance. Liabilities for pension and other postretirement benefits are not considered financial liabilities. 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.

17.    Revenue Recognition

    The Company’s contracts with customers in the scope of Topic 606, Revenue from Contracts with Customers, are contracts for deposit accounts and contracts for non-deposit investment accounts through a third-party service provider.  Both types of contracts result in non-interest income being recognized.  The revenue resulting from deposit accounts, which includes fees such as insufficient funds fees, wire transfer fees and out-of-network ATM transaction fees, is included as a component of fees and service charges on the consolidated statements of income.  The revenue resulting from non-deposit investment accounts is included as a component of other income on the Consolidated Statements of Income. 

Revenue from contracts with customers included in fees and service charges and other income was as follows:

	Three Months Ended September 30,			Nine Months Ended September 30,
	2020		2019	2020	2019
	(Dollars in thousands)
Revenue from contracts with customers included in:
Fees and service charges	$	3,369	4,337	10,227	11,350
Other income	3,444		2,230	8,428	6,961
Total revenue from contracts with customers	$	6,813	6,567	18,655	18,311

    For our contracts with customers, we satisfy our performance obligations each day as services are rendered.  For our deposit account revenue, we receive payment on a daily basis as services are rendered and for our non-deposit investment account revenue, we receive payment on a monthly basis from our third-party service provider as services are rendered.

18.    Recent Accounting Pronouncements

Standard	Description	Required date of adoption	Effect on Consolidated Financial Statements
Standards Adopted in 2020
Measurement of Credit Losses on Financial Instruments	This ASU changes how entities report credit losses for financial assets held at amortized cost and available-for-sale debt securities. The amendments replace the “incurred loss” approach with a methodology that incorporates macroeconomic forecast assumptions and management judgments applicable to and through the expected life of the portfolios based on relevant information about past events, including historical loss experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. The amendments apply to financial assets such as loans, leases and held-to-maturity investments; and certain off-balance sheet credit exposures. The amendments expand credit quality disclosure requirements.	January 1, 2020	The Company adopted the standard’s provisions and all of its related updates on January 1, 2020. The amendments were applied on a modified retrospective basis. See Note 1 - Summary of Significant Accounting Principles for information on the impact of the adoption of ASU 2016-13 on the Company’s Consolidated Financial Statements.
Intangibles-Goodwill and Other- Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force)	This new guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Specifically, where a cloud computing arrangement includes a license to internal-use software, the software license is accounted for by the customer in accordance with Subtopic 350-40, “Intangibles- Goodwill and Other-Internal-Use Software”.	January 1, 2020 Early adoption permitted	The Company will apply the amendments in this Update prospectively to all implementation costs incurred after January 1, 2020. The adoption of ASU No. 2018-15 did not have an impact on the Company’s Consolidated Financial Statements.
Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement	The amendments remove the requirement to disclose the amount of, and reasons for, transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of such transfers and the valuation processes for Level 3 fair value measurements. The ASU modifies the disclosure requirements for investments in certain entities that calculate net asset value and clarify the purpose of the measurement uncertainty disclosure. The ASU adds disclosure requirements about the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements.	January 1, 2020 Early adoption permitted to any removed or modified disclosures and delay of adoption of additional disclosures until the effective date	Changes should be applied retrospectively to all periods presented upon the effective date with the exception of the following, which should be applied prospectively: disclosures relating to changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the disclosures for uncertainty measurement. The adoption of ASU 2018-13 did not have an impact on the Company’s Consolidated Financial Statements.

46

Standard	Description	Required date of adoption	Effect on Consolidated Financial Statements
Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment	This ASU simplifies subsequent measurement of goodwill by eliminating Step 2 of the impairment test while retaining the option to perform the qualitative assessment for a reporting unit to determine whether the quantitative impairment test is necessary. The ASU also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units.	January 1, 2020 Early adoption permitted for interim or annual goodwill impairment testing dates beginning after January 1, 2017	The Company is applying the amendments in ASU 2017-04 prospectively for goodwill impairment testing conducted after January 1, 2020.
Standards Not Yet Adopted
Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity	The amendments simplify the accounting for certain financial instruments with the characteristics of liabilities and equity by reducing the number of models for convertible debt instruments and convertible preferred stock and amends how convertible instruments and equity contracts with an option to be settled in cash or shares affect the EPS calculation. The update also amends the derivatives scope exception for contracts in an entity’s own equity.	January 1, 2022 Early adoption permitted not earlier than fiscal years beginning 2021	The update is not expected to have a material impact on the Company’s Consolidated Financial Statements.
Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting	The amendments provide expedients and exceptions for applying GAAP to contracts or hedging relationships affected by the discontinuance of LIBOR as a benchmark rate to alleviate the burden and cost of such modifications. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments also provide a one-time election to sell and/or transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform.	Effective for a limited time as of March 12, 2020 through December 31, 2022	The Company is evaluating its financial instruments indexed to USD-LIBOR for which the amendments provide expedients and administrative relief.
Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force)	This update clarifies the application of the alternative provided in ASU 2016-01 to measure certain equity securities without a readily determinable fair value. The amendments in this update clarify that a company should consider observable transactions that require it to either apply or discontinue the equity method of accounting under Topic 323 for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments further provide clarification related to the accounting for certain forward contracts and purchased options.	January 1, 2021 Early adoption permitted	The update is to be applied prospectively. The Company does not expect ASU 2020-01 to have a material impact on its Consolidated Financial Statements.

Standard	Description	Required date of adoption	Effect on Consolidated Financial Statements
Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes	The amendments simplify the accounting for income taxes by removing certain exceptions to general principles in Topic 740 and also clarify and amend existing guidance.	January 1, 2021 Early adoption permitted	This update will be effective for the Company January 1, 2021 with early adoption permitted. The Company does not expect ASU No. 2019-12 to have a material impact on its Consolidated Financial Statements.
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 postretirement plans by removing disclosures that no longer are considered cost beneficial, clarifying the specific requirements of disclosures, and adding disclosure requirements identified as relevant.	January 1, 2021 Early adoption permitted	The update is to be applied on a retrospective basis. The Company will evaluate the effect of ASU 2018-14 on disclosures with regard to employee benefit plans but does not expect a material impact on the Company’s Consolidated Financial Statements.

19.    Subsequent Events

    As defined in FASB ASC 855, “Subsequent Events”, subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued or available to be issued. Financial statements are considered issued when they are widely distributed to stockholders and other financial statement users for general use and reliance in a form and format that complies with U.S. GAAP.

Dividend

    On October 28, 2020, the Company declared a cash dividend of $0.12 per share. The $0.12 dividend per share will be paid to stockholders on November 25, 2020, with a record date of November 10, 2020.

Sale-Leaseback Transactions

On August 3, 2020, the Bank entered into an agreement for the sale-leaseback of 15 branch locations, subject to buyer due diligence. The transaction was not completed as of September 30, 2020 and therefore, was not reflected in the Consolidated Financial Statements as of September 30, 2020. As of November 6, 2020, a portion of the transaction has been completed and the remainder of the transaction is expected to be completed in the fourth quarter of 2020. The Company expects to realize an after-tax gain of approximately $7 million net of transaction related expenses in the fourth quarter of 2020.

On November 3, 2020, the Bank entered into an agreement for the sale-leaseback of a corporate office location, subject to buyer due diligence. The transaction is expected to close in the fourth quarter of 2020 and the Company expects to realize an after-tax gain of approximately $10 million net of transaction related expenses.

Non-Performing Loan Sale

On October 30, 2020, the Company sold a non-performing multi-family loan with a net unpaid principal balance of $18.1 million as of September 30, 2020. The Company expects to recognize a recovery of approximately $2 million in the allowance for credit losses in connection with the sale.

Debt Extinguishment

During October 2020, the Company extinguished approximately $600 million of borrowings, which resulted in a cost of approximately $8.6 million.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Forward Looking Statements

    Certain statements contained herein are not based on historical facts and are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Such forward-looking statements may be identified by reference to a future period or periods or by the use of forward-looking terminology, such as “may,” “will,” “believe,” “expect,” “estimate,” “anticipate,” “continue,” or similar terms or variations on those terms, or the negative of those terms. Forward-looking statements are subject to numerous risks and uncertainties, including, but not limited to, those related to the economic environment, particularly in the market areas in which Investors Bancorp, Inc. (the “Company”) operates, competitive products and pricing, fiscal and monetary policies of the U.S. Government, changes in government regulations or interpretations of regulations affecting financial institutions, changes in prevailing interest rates, acquisitions and the integration of acquired businesses, credit risk management, asset-liability management, the financial and securities markets and the availability of and costs associated with sources of liquidity. In addition, the COVID-19 pandemic is having an adverse impact on us, our customers and the communities we serve. The adverse effect of the COVID-19 pandemic on us, our customers and the communities where we operate may adversely affect our business, results of operations and financial condition for an indefinite period of time. Reference is made to Item 1A “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 as well as the Company’s subsequent quarterly reports on Form 10-Q and the additional risk factor included in Part II, Item 1A of this Quarterly Report on Form 10-Q.

    The Company wishes to caution readers not to place undue reliance on any such forward-looking statements, which speak only as of the date made. The Company wishes to advise that the factors listed above could affect the Company’s financial performance and could cause the Company’s actual results for future periods to differ materially from any opinions or statements expressed with respect to future periods in any current statements. The Company does not undertake and specifically declines any obligation to publicly release the result of any revisions, which may be made to any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events except as may be required by law.

Critical Accounting Policies

We consider accounting policies that require management to exercise significant judgment or discretion or to make significant assumptions that have, or could have, a material impact on the carrying value of certain assets or on income to be critical accounting policies. As of September 30, 2020, we consider the following to be our critical accounting policies.

Allowance for Credit Losses. The allowance for credit losses includes both the allowance for loan and lease losses and the reserve for unfunded lending commitments and represents the estimated amount considered necessary to cover lifetime expected credit losses inherent in financial assets at the balance sheet date. The measurement of expected credit losses is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures such as loan commitments and unused lines of credit. The allowance is established through the provision for credit losses that is charged against income. The methodology for determining the allowance for credit losses is considered a critical accounting policy by management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment that could result in changes to the amount of the recorded allowance for credit losses. The allowance for loan and security losses is reported separately as contra-assets to loans and securities on the consolidated balance sheet. The expected credit loss for unfunded lending commitments and unfunded loan commitments is reported on the consolidated balance sheet in other liabilities. The provision for credit losses related to loans, unfunded commitments and debt securities is reported on the consolidated statement of income.

Allowance for Credit Losses on Loans Receivable

    The allowance for credit losses on loans is deducted from the amortized cost basis of the loan to present the net amount expected to be collected. Expected losses are evaluated and calculated on a collective basis for those loans which share similar risk characteristics. At each reporting period, the Company evaluates whether the loans in a pool continue to exhibit similar risk characteristics as the other loans in the pool. If the risk characteristics of a loan change, such that they are no longer similar to other loans in the pool, the Company will evaluate the loan with a different pool of loans that share similar risk characteristics. If the loan does not share risk characteristics with other loans, the Company will evaluate the allowance on an individual basis. The Company evaluates the segmentation at least annually to determine whether loans continue to share similar risk characteristics. Loans are charged off against the allowance when the Company believes the loan balances become

49

uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged off or expected to be charged off.

    The Company has chosen to segment its portfolio consistent with the manner in which it manages the risk of the type of credit. The Company’s segments for loans include multi-family, commercial real estate, commercial and industrial, construction, residential and consumer.

    The Company calculates estimated credit loss on its loan portfolio typically using a probability of default and loss given default quantitative model methodology. The point in time probability of default and loss given default are then conditioned by macroeconomic scenarios to incorporate reasonable and supportable forecasts that affect the collectability of the reported amount. For a small portion of the loan portfolio, i.e. unsecured consumer loans, small business loans and loans to individuals, the Company utilizes a loss rate method to calculate the expected credit loss of that asset segment.

    The Company estimates the allowance for credit losses on loans using relevant available information from internal and external sources related to past events and current conditions as well as the incorporation of reasonable and supportable forecasts. The Company evaluates the use of multiple economic scenarios and the weighting of those scenarios on a quarterly basis. The scenarios that are chosen and the amount of weighting given to each scenario depend on a variety of factors including third party economists and firms, industry trends and other available published economic information.

    After the reasonable and supportable forecast period, the Company reverts to average historical losses. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by the Company.

    Also included in the allowance for loans are qualitative reserves to cover losses that are expected but, in the Company’s assessment, may not be adequately represented in the quantitative method or the economic assumptions described above. For example, factors that the Company considers include changes in lending policies and procedures, business conditions, the nature and size of the portfolio, portfolio concentrations, the volume and severity of past due loans and non-accrual loans, the effect of external factors such as competition, and the legal and regulatory requirements, among other. Furthermore, the Company considers the inherent uncertainty in quantitative models that are built on historical data.

Individually evaluated

    On a case-by-case basis, the Company may conclude a loan should be evaluated on an individual basis based on its disparate risk characteristics. The Company individually evaluates loans that meet the following criteria for expected credit loss, as the Company has determined that these loans generally do not share similar risk characteristics with other loans in the portfolio:

•Commercial loans with an outstanding balance greater than $1.0 million and on non-accrual status;

•Troubled debt restructured loans; and

•Other commercial loans with greater than $1.0 million in outstanding principal, if management has specific information that it is probable they will not collect all principal amounts due under the contractual terms of the loan agreement.

    When the Company determines that the loan no longer shares similar risk characteristics of other loans in the portfolio, the allowance will be determined on an individual basis using the present value of expected cash flows or, for collateral-dependent loans, the fair value of the collateral as of the reporting date, less estimated selling costs, as applicable, to ensure that the credit loss is not delayed until actual loss. If the fair value of the collateral is less than the amortized cost basis of the loan, the Company will charge off the difference between the fair value of the collateral, less costs to sell at the reporting date and the amortized cost basis of the loan.

Acquired assets

    Acquired assets are included in the Company's calculation of the allowance for credit losses. How the allowance on an acquired asset is recorded depends on whether or not it has been classified as a Purchased Financial Asset with Credit Deterioration (“PCD”). PCD assets are assets acquired at a discount that is due, in part, to credit quality. PCD assets are accounted for in accordance with ASC Subtopic 326-20 and are initially recorded at fair value as determined by the sum of the present value of expected future cash flows and an allowance for credit losses at acquisition. The allowance for PCD assets is recorded through a gross-up effect, while the allowance for acquired non-PCD assets such as loans is recorded through provision expense, consistent with originated loans. Thus, the determination of which assets are PCD and non-PCD can have a

50

significant effect on the accounting for these assets.

    Subsequent to acquisition, the allowance for PCD loans will generally follow the same estimation, provision and charge-off process as non-PCD acquired and originated loans. Additionally, TDR identification for acquired loans (PCD and non-PCD) will be consistent with the TDR identification for originated loans.

Derivative Financial Instruments. As required by ASC 815, the Company records all derivatives on the balance sheet 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. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.  Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge.  The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.  

Executive Summary

COVID-19 Pandemic

    Beginning in March 2020, the impacts of the COVID-19 pandemic, including social distancing guidelines, closure of non-essential businesses and shelter-at-home mandates, caused a global economic downturn. The economic downturn has included a decline in gross domestic product and an increase in unemployment. During the third quarter of 2020, the unemployment rate continued to decline but remained significantly elevated above the pre-pandemic unemployment rate. The COVID-19 pandemic and its impact on the economy have led to actions including the enactment of the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), including the establishment of the Paycheck Protection Program (“PPP”) administered by the U.S. Small Business Administration (“SBA”).

    We continue to monitor developments related to COVID-19, including, but not limited to, its impact on our employees, customers, communities and results of operations. During the first quarter of 2020, the majority of our corporate workforce had transitioned to working remotely and we successfully transitioned to a “limited service” branch model including drive-thru operations and ATM services, as well as in-branch services available by appointment only. During the second quarter of 2020, all of our branches resumed normal operating hours and all lobbies re-opened for our clients. In addition, the majority of our corporate workforce have returned to our corporate offices in some capacity and the remainder continues to work remotely in an effective manner. Proper protocols have been put in place in our branches and corporate offices to ensure the continued safety of our employees and customers.

    While we have continued to support our customers by granting second payment deferrals for those experiencing continued hardship because of the pandemic, we have also worked diligently with our customers to ensure a return to current payment status for a significant portion of our clients who have ended their initial deferral period. At October 20, 2020, loans with an aggregate outstanding balance of approximately $730 million, or 3% of total loans, were in COVID-19 related deferment. Based on information available as of October 20, 2020, approximately $300 million of deferments are expected to expire during the fourth quarter of 2020.

    Given the unprecedented uncertainty and continually evolving economic effects and social impacts of the COVID-19 pandemic, the future direct and indirect impact on our business, results of operations and financial condition are highly uncertain. Should current economic conditions persist or continue to deteriorate, we expect that this macroeconomic environment will have a continued adverse effect on our business and results of operations, including additional borrower deferral requests, delinquent loans and non-accrual loans. For more information on how the risks related to COVID-19 may adversely affect our business, results of operations and financial condition, see the additional risk factor included in Part II, Item 1A of this Quarterly Report on Form 10-Q.

Provision for Credit Losses. Our provision for credit losses is primarily a result of the expected credit losses on our loans, unfunded commitments and held-to-maturity debt securities over the life of these financial instruments, including the inherent credit risk in these financial instruments, the composition of and changes in our portfolios of these financial instruments, and the level of charge-offs. At September 30, 2020, our allowance for credit losses and related provision continued to be affected by the impact of COVID-19 on the current and forecasted economic conditions. For the three months ended September 30, 2020, there was improvement in the U.S. and global macroeconomic consensus outlooks, which resulted in an improvement in the economic outlook used to determine the provision for credit losses when compared to June 30, 2020. For the three months ended September 30, 2020, our provision for credit losses was $8.3 million, compared to a negative provision of $2.5 million for the three months ended September 30, 2019. For the three months ended September 30, 2020, net charge-offs were $667,000 compared to $1.5 million for the three months ended September 30, 2019. For the nine months ended September 30, 2020, our provision for credit losses was $72.8 million, compared to a negative provision of $2.5 million for the nine months ended September 30, 2019. For the nine months ended September 30, 2020, net charge-offs were $12.8 million compared to $5.3 million for the nine months ended September 30, 2019.

    Non-Interest Income. Total non-interest income increased $5.1 million to $19.9 million for the three months ended September 30, 2020. This increase was primarily due to gain on loans, which increased $3.6 million due to a higher volume of mortgage banking loan sales to third parties.

    Total non-interest income increased $11.8 million to $44.7 million for the nine months ended September 30, 2020. This increase was primarily due to gain on loans, which increased $7.6 million as a result of a higher volume of mortgage

54

banking loan sales to third parties. In addition, the Company recognized a $5.7 million loss on the sale of securities during the second quarter of 2019.

    Non-Interest Expenses. Total non-interest expenses were $104.1 million for the three months ended September 30, 2020, a decrease of $4.7 million, or 4.3%, compared to the three months ended September 30, 2019. The decrease was due to a decrease of $3.7 million in compensation and benefit expense driven by lower headcount, stock-based compensation expense and benefits expense. Included in non-interest expenses for the three months ended September 30, 2020 were $965,000 of costs from the early extinguishment of $200 million of borrowings.

    Total non-interest expenses were $306.6 million for the nine months ended September 30, 2020, a decrease of $9.3 million, or 2.9%, compared to the nine months ended September 30, 2019. This decrease was due to a decrease of $8.4 million in compensation and fringe benefit expense, a decrease of $4.0 million in advertising and promotional expense and a decrease of $2.5 million in other non-interest expense. These decreases were partially offset by an increase of $2.7 million in data processing and communication expense and an increase of $2.0 million in occupancy expense. Included in non-interest expenses for the nine months ended September 30, 2020 were $3.6 million of Gold Coast acquisition-related expenses.

    Income Taxes. Income tax expense for the third quarter of 2020 was $24.8 million compared to $21.0 million for the third quarter 2019.  The effective tax rate was 27.9% for the three months ended September 30, 2020 and 28.8% for the three months ended September 30, 2019. Income tax expense for the nine months ended September 30, 2020 was $55.7 million compared to $59.1 million the nine months ended September 30, 2019.  The effective tax rate was 27.6% for the nine months ended September 30, 2020 and 28.7% for the nine months ended September 30, 2019. The effective tax rate is affected by the level of income earned that is exempt from tax relative to the overall level of pre-tax income and the level of expenses not deductible for tax purposes relative to the overall level of pre-tax income. In addition, the effective tax rate is affected by the level of income allocated to the various state and local jurisdictions where we operate, because tax rates differ among such jurisdictions.

Analysis of Net Interest Income

Net interest income represents the difference between income we earn on our interest-earning assets and the expense we pay on interest-bearing liabilities. Net interest income depends on the volume of interest-earning assets and interest-bearing liabilities and the interest rates earned on such assets and paid on such liabilities.

Average Balances and Yields. The following tables set forth average balance sheets, average yields and costs, and certain other information for the periods indicated. No tax-equivalent yield adjustments were made, as the effect thereof was not material. All average balances are daily average balances. Non-accrual loans were included in the computation of average balances, however interest receivable on these loans have been fully reserved for and not included in interest income. The yields set forth below include the effect of deferred fees, discounts and premiums, and purchase accounting adjustments and other adjustments that are amortized or accreted to interest income or expense.

Comparison of Financial Condition at September 30, 2020 and December 31, 2019

    Total Assets. Total assets decreased by $91.8 million, or 0.3%, to $26.61 billion at September 30, 2020 from December 31, 2019. Cash and cash equivalents increased by $382.8 million to $557.7 million at September 30, 2020 from December 31, 2019 and securities increased by $224.0 million, or 5.8%, to $4.07 billion at September 30, 2020 from December 31, 2019. Net loans decreased by $778.0 million, or 3.6%, to $20.70 billion at September 30, 2020 from December 31, 2019.

    Net Loans. Net loans decreased by $778.0 million, or 3.6%, to $20.70 billion at September 30, 2020 from $21.48 billion at December 31, 2019. The detail of the loan portfolio is below:

    During the nine months ended September 30, 2020, we originated or funded $814.3 million in commercial and industrial loans (including $334.7 million of PPP loans), $733.9 million in multi-family loans, $447.8 million in residential loans, $368.9 million in commercial real estate loans, $67.3 million in consumer and other loans and $59.0 million in construction loans. Our originations reflect our continued focus on diversifying our loan portfolio. In addition, we acquired $453.3 million of loans from Gold Coast on April 3, 2020. A significant portion of our commercial loan portfolio, including commercial and industrial loans, are secured by commercial real estate and are primarily on properties and businesses located in New Jersey and New York.

    One of our key operating objectives has been, and continues to be, maintaining a high level of asset quality. We maintain sound credit standards for new loan originations and purchases. We do not originate or purchase sub-prime loans, negative amortization loans or option ARM loans. Our portfolio contains interest-only and no income verification residential mortgage loans. At September 30, 2020, interest-only residential and consumer loans totaled $35.4 million, which represented less than 1% of the residential and consumer portfolios. We no longer originate residential mortgage loans without verifying income. At September 30, 2020, these loans totaled $116.4 million. From time to time and for competitive purposes, we originate interest-only commercial real estate and multi-family loans. At September 30, 2020, these loans totaled $1.32 billion. As part of our underwriting, these loans are evaluated as fully amortizing for risk classification purposes, with the interest-only period ranging from one to ten years. In addition, we evaluate our policy limits on a regular basis. We believe these criteria adequately control the potential risks of such loans and that adequate provisions for loan losses are provided for all known and inherent risks.

Allowance for loan losses as a percent of total loans		1.37		%		1.28		%		1.14		%		1.05		%		1.05		%

    Total non-accrual loans were $132.0 million at September 30, 2020 compared to $126.8 million at June 30, 2020 and $92.1 million at September 30, 2019. At September 30, 2020 there were $7.1 million of commercial real estate loans, $5.4 million of commercial and industrial loans and $1.6 million of multi-family loans that were classified as non-accrual which were performing in accordance with their contractual terms. Criticized and classified loans as a percent of total loans increased to 7.47% at September 30, 2020 from 5.36% at December 31, 2019. We continue to proactively and diligently work to resolve our troubled loans.

On October 30, 2020, the Company sold a non-performing multi-family loan with a net unpaid principal balance of $18.1 million as of September 30, 2020. The Company expects to recognize a recovery of approximately $2 million in the allowance for credit losses in connection with the sale.

    At September 30, 2020, there were $35.7 million of loans deemed as TDRs, of which $26.5 million were residential and consumer loans, $5.4 million were commercial real estate loans and $3.8 million were commercial and industrial loans. TDRs of $9.8 million were classified as accruing and $25.9 million were classified as non-accrual at September 30, 2020. Included are $1.8 million of residential loans deemed to be TDRs as the borrower was granted a payment deferral related to COVID-19 but did not meet the criteria to be excluded from TDR as described in Note 1, Summary of Significant Accounting Principles - Section 4013 of the CARES Act.

    In addition to non-accrual loans, we continue to monitor our portfolio for potential problem loans. Potential problem loans are defined as loans about which we have concerns as to the ability of the borrower to comply with the current loan repayment terms and which may cause the loan to be placed on non-accrual status. As of September 30, 2020, the Company has deemed potential problem loans totaling $192.1 million, which is comprised of 16 commercial and industrial loans totaling $119.5 million, 15 commercial real estate loans totaling $65.2 million and 7 multi-family loans totaling $7.4 million. In addition, we continue to support our customers by deferring payments for borrowers experiencing hardship because of the COVID-19 pandemic. As of October 20, 2020, $730 million, or 3%, of loans were deferring principal and/or interest payments. For further information, please refer to the Executive Summary above and the additional risk factor included in Part II, Item 1A of this Quarterly Report on Form 10-Q. Management is actively monitoring all of these loans.

    The ratio of non-accrual loans to total loans was 0.63% at September 30, 2020 compared to 0.44% at December 31, 2019. The allowance for loan losses as a percentage of non-accrual loans was 217.75% at September 30, 2020 compared to 239.66% at December 31, 2019. At September 30, 2020, our allowance for loan losses as a percentage of total loans was 1.37% compared to 1.05% at December 31, 2019.

    The allowance for loan losses increased by $59.4 million to $287.5 million at September 30, 2020 from $228.1 million at December 31, 2019. The increase reflects an increase of $71.5 million from the provision for credit losses related to our loan portfolio and an increase of $4.2 million from the initial allowance on PCD loans upon acquisition, partially offset by a decrease of $12.8 million resulting from net charge-offs and a decrease of $3.6 million upon CECL adoption. Our allowance for loan losses at September 30, 2020 continued to be affected by the impact of COVID-19 on current and forecasted economic conditions. Future increases in the allowance for loan losses may be necessary based on the composition of and change in the loan portfolio, the level of loan delinquency and the current and forecasted economic condition over the life of our loans.

    The following table sets forth the allowance for loan losses at September 30, 2020 and December 31, 2019 allocated by loan category and the percent of loans in each category to total loans at the dates indicated. The allowance for loan losses allocated to each category is not necessarily indicative of future losses in any particular category and does not restrict the use of the allowance to absorb losses in other categories.

Securities. Securities are held primarily for liquidity, interest rate risk management and yield enhancement. Our Investment Policy requires that investment transactions conform to Federal and State investment regulations. Our investments purchased may include, but are not limited to, U.S. Treasury obligations, securities issued by various Federal Agencies, State and Municipal subdivisions, mortgage-backed securities, certain certificates of deposit of insured financial institutions, overnight and short-term loans to other banks, investment grade corporate debt instruments, and mutual funds. In addition, the Company may invest in equity securities subject to certain limitations. Purchase decisions are based upon a thorough analysis of each security to determine if it conforms to our overall asset/liability management objectives. The analysis must consider its effect on our risk-based capital measurement, prospects for yield and/or appreciation and other risk factors. Debt securities are classified as held-to-maturity or available-for-sale when purchased.

    At September 30, 2020, our securities portfolio represented 15.3% of our total assets. Securities, in the aggregate, increased by $224.0 million, or 5.8%, to $4.07 billion at September 30, 2020 from December 31, 2019. This increase was primarily a result of purchases, partially offset by paydowns. At September 30, 2020, our allowance for credit losses on held-to-maturity debt securities was $3.1 million.

Stock in the Federal Home Loan Bank, Bank Owned Life Insurance and Other Assets. The amount of stock we own in the FHLB decreased by $53.0 million, or 19.8%, to $214.3 million at September 30, 2020 from $267.2 million at December 31, 2019. The amount of stock we own in the FHLB is primarily related to the balance of our outstanding borrowings from the FHLB. Bank owned life insurance was $223.6 million at September 30, 2020 and $218.5 million at December 31, 2019. Other assets were $163.5 million at September 30, 2020 and $82.3 million at December 31, 2019. The increase in other assets was primarily driven by hedge-related assets.

60

Deposits.  At September 30, 2020, deposits totaled $19.10 billion, representing 79.8% of our total liabilities. Our long-term deposit strategy is focused on attracting core deposits (savings, checking and money market accounts), resulting in a deposit mix of lower cost core products. We remain committed to our plan of attracting more core deposits because core deposits represent a more stable source of low cost funding and may be less sensitive to changes in market interest rates than other types of funding including borrowed funds.

We have a suite of commercial deposit products, designed to appeal to small and mid-sized businesses and non-profit organizations. Interest rates, maturity terms, service fees and withdrawal penalties are all reviewed on a periodic basis. Deposit rates and terms are based primarily on our current operating strategies, market rates, liquidity requirements, competitive forces and growth goals. We also rely on personalized customer service, long-standing relationships with customers and an active marketing program to attract and retain deposits.

Deposits increased by $1.24 billion, or 7.0%, to $19.10 billion at September 30, 2020 from $17.86 billion at December 31, 2019 primarily driven by increases in checking and money market deposits, offset by a decrease in time deposits. Checking accounts increased $1.06 billion to $9.04 billion at September 30, 2020 from $7.99 billion at December 31, 2019. Core deposits represented approximately 81% of our total deposit portfolio at September 30, 2020 compared to 78% at December 31, 2019.

The following table sets forth the distribution of total deposit accounts, by account type, at the dates indicated:

	September 30, 2020				December 31, 2019
	Balance		Percent of Total Deposit		Balance		Percent of Total Deposit
	(Dollars in thousands)
Non-interest bearing:
Checking accounts	$	3,345,011	17.5	%	$	2,472,232	13.8	%
Interest-bearing:
Checking accounts	5,696,645		29.8	%	5,512,979		30.9	%
Money market deposits	4,369,733		22.9	%	3,817,718		21.4	%
Savings	2,008,540		10.5	%	2,050,101		11.5	%
Certificates of deposit	3,683,606		19.3	%	4,007,308		22.4	%
Total Deposits	$	19,103,535	100.0	%	$	17,860,338	100.0	%

Borrowed Funds.  Borrowings are primarily with the FHLB and are collateralized by our residential and commercial mortgage portfolios. Borrowed funds decreased by $1.52 billion, or 26.1%, to $4.31 billion at September 30, 2020 from $5.83 billion at December 31, 2019 primarily driven by the increase in deposits. The decrease includes the early extinguishment of $400 million of borrowings during the second and third quarters of 2020. The extinguishments resulted in the recognition of $326,000 and $965,000 of costs during the second and third quarter, respectively, included in Other operating expenses on the Consolidated Statement of Income.

Other Liabilities. Other liabilities increased by $115.8 million, or 141.6%, to $197.7 million at September 30, 2020 from $81.8 million at December 31, 2019 primarily driven by increases in income taxes payable and our allowance for credit losses on unfunded commitments, as well as a commitment to purchase investment securities. At September 30, 2020, our allowance for credit losses on unfunded commitments was $13.9 million.

Stockholders’ Equity. Stockholders’ equity increased by $47.8 million to $2.67 billion at September 30, 2020 from $2.62 billion at December 31, 2019. The increase was primarily attributed to net income of $146.4 million, common stock issued to finance the Gold Coast acquisition of $20.9 million and share-based plan activity of $14.5 million for the nine months ended September 30, 2020. These increases were partially offset by other comprehensive loss of $32.4 million and cash dividends paid of $0.36 per share totaling $89.7 million during the nine months ended September 30, 2020. In addition, stockholders’ equity decreased by $8.5 million on January 1, 2020 in connection with the adoption of CECL.

Liquidity and Capital Resources

    The Company’s primary sources of funds are deposits, principal and interest payments on loans and mortgage-backed securities, FHLB and other borrowings and, to a lesser extent, proceeds from the sale of loans and investment maturities. While scheduled amortization of loans is usually a predictable source of funds, deposit flows and mortgage prepayments are greatly influenced by general interest rates, economic conditions and competition. The Company has other sources of liquidity, including unsecured overnight lines of credit, brokered deposits and other borrowings from correspondent banks. Available borrowing capacity and other available liquidity sources totaled approximately $11.27 billion at September 30, 2020. Our Asset Liability Committee is responsible for establishing and monitoring our liquidity targets and strategies to ensure that sufficient liquidity exists for meeting the needs of our customers as well as unanticipated contingencies. These liquidity risk management practices have allowed us to effectively manage the market stress that began in the first quarter of 2020 from the COVID-19 pandemic.

    At September 30, 2020, the Company had no overnight borrowings outstanding. The Company had $461.0 million of overnight borrowings outstanding at December 31, 2019. The Company borrows directly from the FHLB and various financial institutions. The Company had total borrowings of $4.31 billion at September 30, 2020, a decrease of $1.52 billion from $5.83 billion at December 31, 2019.

    In the normal course of business, the Company routinely enters into various commitments, primarily relating to the origination of loans. At September 30, 2020, outstanding commitments to originate loans totaled $260.2 million; outstanding unused lines of credit totaled $1.90 billion; standby letters of credit totaled $39.8 million and outstanding commitments to sell loans totaled $69.0 million. The Company expects to have sufficient funds available to meet current commitments in the normal course of business. Time deposits scheduled to mature in one year or less totaled $3.34 billion at September 30, 2020. Based upon historical experience, management estimates that a significant portion of such deposits will remain with the Company.

    Credit ratings and outlooks are opinions expressed by rating agencies on our creditworthiness and that of our obligations or securities, including long-term debt, short-term borrowings, preferred stock and other securities. On May 4, 2020, S&P revised our rating outlook to negative due to economic downturn from COVID-19.

    Regulatory Capital and Developments.

    CECL. On January 1, 2020, the Company adopted the new accounting standard that requires the measurement of the allowance for credit loss to be based on the best estimate of lifetime expected credit losses inherent in the Company’s relevant financial asset. For more information, see Note 1, Summary of Significant Accounting Principles. On March 27, 2020, in response to the COVID-19 pandemic, U.S. banking regulators issued an interim final rule that the Company adopted to delay for two years the initial adoption impact of CECL on regulatory capital, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided during 2020 and 2021 (i.e. a five-year transition period). During the two-year delay, the Company will add back to common equity tier 1 capital (“CET1”) 100% of the initial adoption impact of CECL plus 25% of the cumulative quarterly changes in the allowance for credit losses (i.e., quarterly transitional amounts). After two years, starting on January 1, 2022, the quarterly transitional amounts along with the initial adoption impact of CECL will be phased out of CET1 capital over the three-year period.

    Paycheck Protection Program. On April 9, 2020, in response to the economic impact of the COVID-19 pandemic, the Federal Reserve, OCC and FDIC issued an interim final rule that excludes loans pledged as collateral to the Federal Reserve’s PPP Lending Facility from supplemental leverage ratio exposure, average total consolidated assets and Advanced and Standardized risk-weighted assets. Additionally, PPP loans, which are guaranteed by the Small Business Administration, will receive a zero percent risk weight under the Basel 3 Advanced and Standardized approaches regardless of whether they are pledged as collateral to the PPP Lending Facility.

    Minimum Capital Requirements. In July 2013, the Federal Deposit Insurance Corporation and the other federal bank regulatory agencies issued a final rule that revised their leverage and risk-based capital requirements and the method for calculating risk-weighted assets to make them consistent with agreements that were reached by the Basel Committee on Banking Supervision and certain provisions of the Dodd-Frank Act. The Final Capital Rules also revised the quantity and quality of required minimum risk-based and leverage capital requirements, consistent with the Reform Act and the Third Basel Accord adopted by the Basel Committee on Banking Supervision, or Basel III capital standards. In doing so, the Final Capital Rules:

•Established a new minimum Common equity tier 1 risk-based capital ratio (common equity tier 1 capital to total risk-weighted assets) of 4.5% and increased the minimum Tier 1 risk-based capital ratio from 4.0% to 6.0%, while maintaining the minimum Total risk-based capital ratio of 8.0% and the minimum Tier 1 leverage capital ratio of 4.0%.

62

•Revised the rules for calculating risk-weighted assets to enhance their risk sensitivity.

•Phased out trust preferred securities and cumulative perpetual preferred stock as Tier 1 capital.

•Added a requirement to maintain a minimum Conservation Buffer, composed of Common equity tier 1 capital, of 2.5% of risk-weighted assets, to be applied to the new Common equity tier 1 risk-based capital ratio, the Tier 1 risk-based capital ratio and the Total risk-based capital ratio, which means that banking organizations, on a fully phased in basis as of January 1, 2019, must maintain a minimum Common equity tier 1 risk-based capital ratio of 7.0%, a minimum Tier 1 risk-based capital ratio of 8.5% and a minimum Total risk-based capital ratio of 10.5% or have restrictions imposed on capital distributions and discretionary cash bonus payments.

•Changed the definitions of capital categories for insured depository institutions for purposes of the Federal Deposit Insurance Corporation Improvement Act of 1991 prompt corrective action provisions. Under these revised definitions, to be considered well-capitalized, an insured depository institution must have a Tier 1 leverage capital ratio of at least 5.0%, a Common equity tier 1 risk-based capital ratio of at least 6.5%, a Tier 1 risk-based capital ratio of at least 8.0% and a Total risk-based capital ratio of at least 10.0%.

    The new minimum regulatory capital ratios and changes to the calculation of risk-weighted assets became effective for the Bank and Company on January 1, 2015. The required minimum Conservation Buffer commenced on January 1, 2016 at 0.625% and increased in annual increments to 2.5% on January 1, 2019, which is the fully phased in Conservation Buffer. The rules impose restrictions on capital distributions and certain discretionary cash bonus payments if the minimum Conservation Buffer is not met. As of September 30, 2020, the Company and the Bank met the required Conservation Buffer of 2.5%.

As of September 30, 2020, the Bank and the Company were considered “well capitalized” under applicable regulations and exceeded all regulatory capital requirements as follows:

	As of September 30, 2020 (1)

Off-Balance Sheet Arrangements and Aggregate Contractual Obligations

    In the ordinary course of its operations, the Company engages in a variety of financial transactions that, in accordance with U.S. generally accepted accounting principles, are not recorded in the financial statements.

The following table shows the contractual obligations of the Company by expected payment period as of September 30, 2020:

Contractual Obligations	Total		Less than One Year	One-Two Years	Two-Three Years	More than Three Years
	(In thousands)
Debt obligations (excluding capitalized leases)	$	4,307,523	350,000	1,198,975	1,199,363	1,559,185
Commitments to originate and purchase loans	$	260,157	260,157	—	—	—
Commitments to sell loans	$	69,000	69,000	—	—	—

63

    Debt obligations include borrowings from the FHLB and other borrowings. The borrowings have defined terms, and none of the borrowings were callable at the option of the lender as of September 30, 2020. Additionally, at September 30, 2020, the Company’s commitments to fund unused lines of credit totaled $1.90 billion. Commitments to originate loans, commitments to fund unused lines of credit and standby letters of credit are agreements to lend additional funds to customers as long as there have been no violations of any of the conditions established in the agreements. Commitments generally have a fixed expiration or other termination clauses which may or may not require a payment of a fee. Since some of these loan commitments are expected to expire without being drawn upon, total commitments do not necessarily represent future cash requirements.

    In addition to the contractual obligations previously discussed, we have other liabilities which include $184.3 million of operating lease liabilities of which $3.6 million was acquired from Gold Coast during the three months ended June 30, 2020. We have $2.8 million of finance lease liabilities. These contractual obligations as of September 30, 2020 have not changed significantly from December 31, 2019.

    In the normal course of business, the Company sells residential mortgage loans to third parties. These loan sales are subject to customary representations and warranties. In the event that we are found to be in breach of these representations and warranties, we may be obligated to repurchase certain of these loans.

    The Company has entered into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Derivative financial instruments present on the Company’s balance sheet as of September 30. 2020 are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s borrowings. During the three and nine months ended September 30, 2020, such derivatives were used to hedge the variability in cash flows associated with borrowings. These derivatives had an aggregate notional amount of $3.53 billion as of September 30, 2020. The fair value of derivatives designated as hedging activities as of September 30, 2020 was an asset of $153,000, inclusive of accrued interest and variation margin posted in accordance with the Chicago Mercantile Exchange. Derivatives with an aggregate notional amount of $475.0 million that had been used to hedge changes in the fair value of certain pools of prepayable fixed- and adjustable-rate assets were terminated during the three months ended September 30, 2020.

    The Company has credit derivatives resulting from participations in interest rate swaps provided to external lenders as part of loan participation arrangements which are, therefore, not used to manage interest rate risk in the Company’s assets or liabilities. Additionally, the Company provides interest rate risk management services to commercial customers, primarily interest rate swaps. The Company’s market risk from unfavorable movements in interest rates related to these derivative contracts is minimized by concurrently entering into offsetting derivative contracts that have identical notional values, terms and indices.

    For further information regarding our off-balance sheet arrangements and contractual obligations, see Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in our December 31, 2019 Annual Report on Form 10-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

    Qualitative Analysis. One significant form of market risk is interest rate risk. Interest rate risk results from timing differences in the cash flow or re-pricing of our assets, liabilities and off-balance sheet contracts (i.e., loan commitments); the effect of loan prepayments, deposit activity; potential differences in the behavior of lending and funding rates arising from the use of different indices; and “yield curve risk” arising from changes in the term structure of interest rates. Changes in market interest rates can affect net interest income by influencing the amount and rate of new loan originations, the ability of borrowers to repay variable rate loans, the volume of loan prepayments and the mix and flow of deposits.

    The general objective of our interest rate risk management process is to determine the appropriate level of risk given our business model and then to manage that risk in a manner consistent with that risk appetite. Our Asset Liability Committee, which consists of senior management and executives, evaluates the interest rate risk inherent in our balance sheet, the operating environment and capital and liquidity requirements and may modify our lending, investing and deposit gathering strategies accordingly. On a quarterly basis, our Board of Directors reviews various Asset Liability Committee reports that estimate the sensitivity of the economic value of equity and net interest income under various interest rate scenarios.

    Our tactics and strategies may include the use of various financial instruments, including derivatives, to manage our exposure to interest rate risk. Certain derivatives are designated as hedging instruments in a qualifying hedge accounting relationship (fair value or cash flow hedge). Hedged items can be either assets or liabilities. As of September 30, 2020, the

64

Company had cash flow hedges with aggregate notional amounts of $3.53 billion. As of December 31, 2019, the Company had cash flow and fair value hedges with aggregate notional amounts of $2.68 billion. Included in the fair value hedges at December 31, 2019 were $475.0 million in asset swap transactions where fixed rate loan payments were exchanged for variable rate payments executed in an effort to reduce the Company’s exposure to rising rates. During the nine months ended September 30, 2020, the Company terminated such asset swap transactions.

    We actively evaluate interest rate risk in connection with our lending, investing and deposit activities and our off-balance sheet positions. At September 30, 2020, 21.0% of our total loan portfolio was comprised of residential mortgages, of which approximately 28.3% was in variable rate products, while 71.7% was in fixed rate products. Our variable rate and short term fixed rate mortgage related assets have helped to reduce our exposure to interest rate fluctuations. Long term fixed-rate products may adversely impact our net interest income in a rising rate environment. The origination of commercial loans, particularly commercial and industrial loans, commercial real estate loans and multi-family loans, which have outpaced the growth in the residential portfolio in recent years, generally help reduce our interest rate risk due to their shorter term compared to fixed rate residential mortgage loans. In addition, we primarily invest in securities which display relatively conservative interest rate risk characteristics.

    We use an internally managed and implemented industry standard asset/liability model to complete our quarterly interest rate risk reports. The model projects net interest income based on various interest rate scenarios and horizons. We use a combination of analyses to monitor our exposure to changes in interest rates.

    Our net interest income sensitivity analysis determines the relative balance between the repricing of assets, liabilities and off-balance sheet positions over various horizons. This asset and liability analysis includes expected cash flows from loans and securities, using forecasted prepayment rates, reinvestment rates, as well as contractual and forecasted liability cash flows. This analysis identifies mismatches in the timing of asset and liability cash flows but does not necessarily provide an accurate indicator of interest rate risk because the rate forecasts and assumptions used in the analysis may not reflect actual experience. The economic value of equity (“EVE”) analysis estimates the change in the net present value (“NPV”) of assets and liabilities and off-balance sheet contracts over a range of immediate rate shock interest rate scenarios. In calculating changes in EVE, for the various scenarios we forecast loan and securities prepayment rates, reinvestment rates and deposit decay rates.

    In July 2017, the Financial Conduct Authority (the authority that regulates LIBOR) announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. The Alternative Reference Rates Committee (“ARRC”) has proposed that the Secured Overnight Financing Rate (“SOFR”) is the rate that represents best practice as the alternative to USD-LIBOR for use in derivatives and other financial contracts that are currently indexed to USD-LIBOR. The ARRC has proposed a paced market transition plan to SOFR from USD-LIBOR and organizations are currently working on industry wide and company specific transition plans as it relates to derivatives and cash markets exposed to USD-LIBOR. The Company has approximately $7.10 billion in financial instruments which are indexed to USD-LIBOR for which it is monitoring the activity and evaluating the related risks.

    Quantitative Analysis. The table below sets forth, as of September 30, 2020, the estimated changes in our EVE and our net interest income that would result from the designated changes in interest rates. Such changes to interest rates are calculated as an immediate and permanent change for the purposes of computing EVE and a gradual change over a one-year period for the purposes of computing net interest income. Computations of prospective effects of hypothetical interest rate changes are based on numerous assumptions including relative levels of market interest rates, loan prepayments, deposit decay, and funding dynamics in a potential negative rate environment, and should not be relied upon as indicative of actual results. The following table reflects management’s expectations of the changes in EVE and net interest income for an interest rate decrease of 100 basis points and increase of 200 basis points.

	EVE (1)					Net Interest Income (2)
Change in Interest Rates (basis points)	Estimated EVE		Estimated Increase (Decrease)			Estimated Net Interest Income		Estimated Increase (Decrease)
			Amount	Percent				Amount	Percent
	(Dollars in thousands)
+ 200bp	$	3,353,226	88,119	2.7	%	$	690,219	(37,834)	(5.2)	%
0bp	$	3,265,107	—	—		$	728,053	—	—
-100bp	$	3,071,156	(193,951)	(5.9)	%	$	735,677	7,624	1.0	%

(1)EVE is the discounted present value of expected cash flows from assets, liabilities and off-balance sheet contracts.

(2)Assumes a gradual change in interest rates over a one-year period at all maturities.

    The table above indicates that at September 30, 2020, in the event of a 200 basis point increase in interest rates, we would be expected to experience a 2.7% increase in EVE and a $37.8 million, or 5.2%, decrease in net interest income. In the

65

event of a 100 basis point decrease in interest rates, we would be expected to experience a 5.9% decrease in EVE and a $7.6 million, or 1.0%, increase in net interest income. This data does not reflect any future actions we may take in response to changes in interest rates, such as changing the mix in or growth of our assets and liabilities, which could change the results of the EVE and net interest income calculations.

    As mentioned above, we use an internally developed asset liability model to compute our quarterly interest rate risk reports. Certain shortcomings are inherent in any methodology used to calculate interest rate risk. Modeling EVE and net interest income sensitivity requires certain assumptions that may or may not reflect the manner in which actual yields and market values respond to changes in market interest rates. The EVE and net interest income results presented above assumes no balance sheet growth and that generally the composition of our interest-rate sensitive assets and liabilities existing at the beginning of the analysis remains constant over the period being measured and, accordingly, the data does not reflect any actions we may take in response to changes in interest rates. The EVE and net interest income results presented in the table above provide an indication of our sensitivity to interest rate changes at a point in time. The results as presented are not intended to, and do not, provide a precise forecast of the effects of changes in market interest rates on our EVE and net interest income.

ITEM 4. CONTROLS AND PROCEDURES

    Under the supervision and with the participation of our management, including our Principal Executive Officer and Principal Financial Officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based upon that evaluation, the Principal Executive Officer and Principal Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective.

    There were no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II Other Information

ITEM 1. LEGAL PROCEEDINGS

    The Company, the Bank and its subsidiaries are subject to various legal actions arising in the normal course of business. In the opinion of management, the resolution of these legal actions is not expected to have a material adverse effect on the Company’s financial condition or results of operations.

ITEM 1A. RISK FACTORS

    In addition to the other information contained in this Quarterly Report on Form 10-Q, the following risk factor represents a material update and addition to the risk factors previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 as filed with the Securities and Exchange Commission. To the extent that any of the information contained in this Quarterly Report on Form 10-Q constitutes forward-looking statements, the risk factor set forth below also is a cautionary statement identifying important factors that could cause our actual results to differ materially from those expressed in any forward-looking statements made by or on behalf of us.

The economic impact of the COVID-19 pandemic may have an adverse impact on our business and results of operations.

    The COVID-19 pandemic, which was declared a national emergency in the United States in March 2020, continues to create extensive disruptions to the global economy and financial markets and to businesses and the lives of individuals throughout the world. Federal and state governments, including in New Jersey and New York, are taking unprecedented actions to contain the spread of the disease, including quarantines, travel bans, shelter-in-place orders, closures of businesses and schools, fiscal stimulus, and legislation designed to deliver monetary aid and other relief to businesses and individuals impacted by the pandemic. Although in various locations certain activity restrictions have been relaxed with some level of success, including in New Jersey and New York, in many states and localities the number of individuals diagnosed with COVID-19 has increased significantly. Reporting of COVID-19 case data as of November 2, 2020 indicates that, on a national level, the number of average positive cases per day has increased by 44% since mid-October. This resurgence of positive cases across a number of jurisdictions has increased pressure on governmental officials to reverse the relaxation of activity restrictions, which could lead to the shutdown of certain businesses and operations and exacerbate economic uncertainty and instability related to the pandemic.

The governmental and social response to the COVID-19 pandemic has resulted in an unprecedented slow-down in economic activity and a related increase in unemployment. Since the outbreak of COVID-19 in the United States, more than 60 million people nationwide have filed claims for unemployment, and stock markets have declined in value and in particular, bank stocks have significantly declined in value. As of the end of September 2020, the national unemployment rate was 7.9%. Although an improvement from the 11.1% national unemployment rate observed in June 2020, the current rate of unemployment is substantially higher than the 3.6% national unemployment rate observed in January 2020 prior to the outbreak of COVID-19 in the United States. Further, the Federal Pandemic Unemployment Compensation Program, which under Section 2104 of the CARES Act allows for additional payments to covered individuals of up to $600 per week, expired as of July 31, 2020 and it is uncertain whether this benefit will be renewed by Congress.    

The COVID-19 pandemic, and related efforts to contain it, have caused significant disruptions in the functioning of the financial markets and have increased economic and market uncertainty and volatility. To help address these issues, the Federal Open Market Committee (“FOMC”) has reduced the benchmark federal funds rate to a target range of 0% to 0.25%, and the yields on 10- and 30-year U.S. Treasury notes have declined to historic lows. At its June and July meetings, the FOMC continued its commitment to this approach, indicating that the target federal funds rate would remain at current levels until the economy is in position to achieve the FOMC’s maximum-employment and price-stability goals. At its September meeting, the FOMC confirmed its commitment to maintaining this approach, indicating that, although financial conditions have improved in the months preceding its meeting, additional stimulus from the federal government is essential to the economy’s recovery. In addition, in order to support the flow of credit to households and businesses, the Federal Reserve indicated that it will continue to increase its holdings of U.S. Treasury securities and agency residential and commercial mortgage-backed securities to sustain proper functioning of the financial markets.

Congress and various state governments and federal agencies have taken actions to require lenders to provide forbearance and other relief to borrowers (e.g., waiving late payment and other fees). The federal banking agencies have encouraged financial institutions to prudently work with affected borrowers, and recently passed legislation has provided relief

67

from reporting loan classifications due to modifications related to the COVID-19 pandemic. More specifically, through Section 4022 of the CARES Act, Congress provided relief to borrowers with federally-backed one-to-four family mortgage loans experiencing a financial hardship due to COVID-19 by allowing such borrowers to request forbearance, regardless of delinquency status, for up to 360 days. Such relief will be available until the earlier of December 31, 2020 and the date of termination of the national emergency declaration. Section 4022 of the CARES Act also prohibited servicers of federally-backed mortgage loans from initiating foreclosures during the 60-day period beginning March 18, 2020. In addition, on August 27, 2020, the Federal Housing Finance Agency (“FHFA”) announced that Fannie Mae and Freddie Mac would extend their single-family moratorium on foreclosures and evicitions through December 31, 2020. At the same time, the Federal Housing Administration (“FHA”) announced an extension of its moratorium on foreclosures and evictions for homeowners with FHA-insured loans, also through December 31, 2020. Under Section 4023 of the CARES Act, until the earlier of December 31, 2020 and the date of termination of the national emergency declaration, borrowers with federally-backed multifamily mortgage loans whose payments were current as of February 1, 2020, but who have since experienced financial hardship due to COVID-19, may request a forbearance for up to 90 days. Borrowers receiving such forbearance may not evict or charge late fees to tenants during the duration of such forbearance.

Additionally, in many states in which we do business or in which our borrowers and loan collateral are located, temporary bans on evictions and foreclosures have been enacted through a mix of executive orders, regulations, and judicial orders. Certain such relief orders have since expired, although several states, including New York and New Jersey, have extended their temporary orders and may continue to do so for so long as the public health emergency persists. In addition, in New York, Governor Andrew Cuomo signed legislation on June 17, 2020 that expands mortgage forbearance available for those experiencing financial hardship during the crisis caused by the COVID-19 pandemic. The legislation applies to those who have mortgages with state-regulated financial institutions and is intended to be an expansion of the CARES Act’s mortgage forbearance provisions. The legislation provides up to one year of forbearance if the borrower’s hardship persists and provides flexible payment options. The New Jersey Legislature currently is debating several comparable legislative proposals.

    Certain industries have been particularly hard-hit by the COVID-19 pandemic, including the travel and hospitality industry, the restaurant industry and the retail industry. Refer to the Executive Summary included in Part I, Item 2 of this Quarterly Report on Form 10-Q for details on the Company’s loan portfolio by industry as of September 30, 2020. In addition, the spread of COVID-19 has caused us to modify our business practices, including employee travel, employee work locations, and cancellation of physical participation in meetings, events and conferences. We have many employees working remotely and we may take further actions as may be required by government authorities or that we determine are in the best interests of our employees, customers and business partners.

    Given the ongoing and dynamic nature of the circumstances, it is difficult to predict the full impact of the COVID-19 outbreak on our business. The extent of such impact will depend on future developments, which are highly uncertain, including when the spread of COVID-19 can be controlled and abated and when and how the economy may be fully reopened. As the result of the COVID-19 pandemic and the related adverse local and national economic consequences, we may be subject to any of the following risks, any of which could have a material, adverse effect on our business, financial condition, liquidity, results of operations, risk-weighted assets and regulatory capital:

•because the incidence of reported COVID-19 cases and related hospitalizations and deaths varies significantly by state and locality, the economic downturn caused by the pandemic may be deeper and more sustained in certain areas, including those in which we do business relative to other areas of the country;

•our ability to market our products and services maybe impaired by a variety of external factors, including a prolonged reduction in economic activity and continued economic and financial market volatility, which could cause demand for our products and services to decline, in turn making it difficult for us to grow assets and income;

•if the economy is unable to substantially reopen, and high levels of unemployment continue for an extended period of time, loan delinquencies, problem assets, and foreclosures may increase, resulting in increased charges and reduced income;

•collateral for loans, especially real estate, may decline in value, which may reduce our ability to liquidate such collateral and could cause loan losses to increase and impair our ability over the long run to maintain our targeted loan origination volume;

•our delinquent and non-accrual loans could increase substantially if borrowers continue to experience financial difficulties beyond forbearance/payment deferral periods resulting in adversely impacted asset quality, capital and earnings. As of October 20, 2020, we had $730 million, or 3%, of loans deferring principal and/or interest payments as a result of COVID-19;

•our allowance for loan losses may have to be increased if borrowers experience financial difficulties beyond forbearance periods, which will adversely affect our net income;

68

•an increase in non-performing loans due to the COVID-19 pandemic would result in a corresponding increase in the risk-weighting of assets and therefore an increase in required regulatory capital;

•the net worth and liquidity of loan guarantors may decline, impairing their ability to honor commitments to us;

•as the result of the reduction of the Federal Reserve’s target federal funds rate to near 0%, the yield on our assets may decline to a greater extent than the decline in our cost of interest-bearing liabilities, reducing our net interest margin and spread and reducing net income;

•deposits, including municipal deposits, could decline if customers need to draw on available balances as a result of the economic downturn;

•a material decrease in net income or a net loss over several quarters could result in a decrease in our quarterly cash dividend;

•we face heightened cybersecurity risk in connection with our operation of a remote working environment, which risks include, among others, greater phishing, malware, and other cybersecurity attacks, vulnerability to disruptions of our information technology infrastructure and telecommunications systems, increased risk of unauthorized dissemination of confidential information, limited ability to restore our systems in the event of a systems failure or interruption, greater risk of a security breach resulting in destruction or misuse of valuable information, and potential impairment of our ability to perform critical functions--all of which could expose us to risks of data or financial loss, litigation and liability and could seriously disrupt our operations and the operations of any impacted customers;

•we rely on third party vendors for certain services and the unavailability of a critical service or limitations on the business capacities of our vendors for extended periods of time due to the COVID-19 pandemic could have an adverse effect on our operations; and

•as a result of the COVID-19 pandemic, there may be unexpected developments in financial markets, legislation, regulations and consumer and customer behavior.

    The Company is not a traditional SBA lender however, we are an active participant in the PPP. The PPP authorizes financial institutions to make federally-guaranteed loans to qualifying small businesses and non-profits organizations. These loans carry an interest rate of 1% per annum and a maturity of two years if originated before June 5, 2020 and five years if originated on or after June 5, 2020. The PPP provides that such loans may be forgiven if the borrowers meet certain requirements with respect to maintaining employee headcount and payroll and the use of the loan proceeds after the loan is originated. If not forgiven, these loans will be guaranteed by the SBA under the SBA’s section 7(a) program. We had approximately $333.4 million of PPP outstanding as of September 30, 2020.

In light of the speed at which the PPP was implemented, particularly due to the “first come first served” nature of the program, the loans originated under this program may present potential fraud risk and operational risk, increasing the risk that loan forgiveness may not be obtained by the borrowers and that the guaranty may not be honored. In addition, there is risk that the borrowers may not qualify for the loan forgiveness feature due to the conduct of the borrower after the loan is originated. Further, although the SBA recently has streamlined the loan forgiveness process for loans of $50,000 or less, it has taken longer than initially anticipated for the SBA to finalize its forgiveness process. Accordingly, absent regulatory relief, extended forbearance waiting times due to SBA-related delays are likely. These factors may result in us having to hold a significant amount of these low-yield loans on our books for a significant period of time. We will continue to face operational demands and pressures as we monitor and service our book of PPP loans, process applications for loan forgiveness and pursue recourse under the SBA’s guarantees and against borrowers for PPP loan defaults. In addition, as a result of our participation in the PPP, we may be subject to litigation and claims by borrowers in connection with the PPP loans that we have made, as well as investigation and scrutiny by our regulators, Congress, the SBA, the U.S. Treasury Department and other governmental authorities. Regardless of whether these claims and investigations may be founded or unfounded, if such claims and investigations are not resolved in a timely and favorable manner for us, they may result in significant costs and liabilities (including increased legal and professional costs) and/or adversely affect the market perception of us and our products and services.

Moreover, our future success and profitability substantially depends on the management skills of our executive officers and directors, many of whom have held officer and director positions with us for many years. The unanticipated loss or unavailability of key employees due to COVID-19 pandemic could harm our ability to operate our business or execute our business strategy. We may not be successful in finding and integrating suitable successors in the event of key employee loss or unavailability. Any one or a combination of the factors identified above could negatively impact our business, financial condition and results of operations and prospects.

Summary of Significant Accounting Principles

Summary of Significant Accounting Principles

Basis of Presentation

    The consolidated financial statements are comprised of the accounts of Investors Bancorp, Inc. and its wholly owned subsidiary, Investors Bank (the “Bank”) and the Bank’s wholly-owned subsidiaries (collectively, the “Company”). In the opinion of management, all the adjustments (consisting of normal and recurring adjustments) necessary for the fair presentation of the consolidated financial condition and the consolidated results of operations for the unaudited periods presented have been included. The results of operations and other data presented for the three and nine months ended September 30, 2020 are not necessarily indicative of the results of operations that may be expected for subsequent periods or the full year results.

    Certain information and note disclosures usually included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for the preparation of the Form 10-Q. The consolidated financial statements presented should be read in conjunction with the Company’s audited consolidated financial statements and notes to the audited consolidated financial statements included in the Company’s December 31, 2019 Annual Report on Form 10-K. Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications.

Adoption of New Accounting Standards

    On January 1, 2020, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The Company adopted ASU 2016-13 using a modified retrospective approach. Results for reporting periods beginning after January 1, 2020 are presented under Topic 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP. At adoption, the Company increased its allowance for credit losses by $11.7 million, comprised of $12.7 million and $2.6 million, respectively, for unfunded commitments and held-to-maturity debt securities, partially offset by a decrease of $3.6 million for loans. Upon adoption the Company recorded a cumulative effect adjustment that reduced stockholders’ equity by $8.5 million, net of tax.

Allowance for Credit Losses    

    The allowance for credit losses includes both the allowance for loan and lease losses and the reserve for unfunded lending commitments and represents the estimated amount considered necessary to cover lifetime expected credit losses inherent in financial assets at the balance sheet date. The measurement of expected credit losses is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures such as loan commitments and unused lines of credit. The allowance is established through the provision for credit losses that is charged against income. The methodology for determining the allowance for credit losses is considered a critical accounting policy by management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment that could result in changes to the amount of the recorded allowance for credit losses. The allowance for loan and security losses is reported separately as contra-assets to loans and securities on the consolidated balance sheet. The expected credit loss for unfunded lending commitments and unfunded loan commitments is reported on the consolidated balance sheet in other liabilities. The provision for credit losses related to loans, unfunded commitments and debt securities is reported on the consolidated statement of income.

Allowance for Credit Losses on Loans Receivable

    The allowance for credit losses on loans is deducted from the amortized cost basis of the loan to present the net amount expected to be collected. Expected losses are evaluated and calculated on a collective basis for those loans which share similar risk characteristics. At each reporting period, the Company evaluates whether the loans in a pool continue to exhibit similar risk characteristics as the other loans in the pool. If the risk characteristics of a loan change, such that they are no longer similar to other loans in the pool, the Company will evaluate the loan with a different pool of loans that share similar risk characteristics. If the loan does not share risk characteristics with other loans, the Company will evaluate the allowance on an individual basis. The Company evaluates the segmentation at least annually to determine whether loans continue to share similar risk characteristics. Loans are charged off against the allowance when the Company believes the loan balances become uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged off or expected to be charged off.

    The Company has chosen to segment its portfolio consistent with the manner in which it manages the risk of the type of credit. The Company’s segments for loans include multi-family, commercial real estate, commercial and industrial, construction, residential and consumer.

    The Company calculates estimated credit loss on its loan portfolio typically using a probability of default and loss given default quantitative model methodology. The point in time probability of default and loss given default are then conditioned by macroeconomic scenarios to incorporate reasonable and supportable forecasts that affect the collectability of the reported amount. For a small portion of the loan portfolio, i.e. unsecured consumer loans, small business loans and loans to individuals, the Company utilizes a loss rate method to calculate the expected credit loss of that asset segment.

    The Company estimates the allowance for credit losses on loans using relevant available information from internal and external sources related to past events and current conditions as well as the incorporation of reasonable and supportable forecasts. The Company evaluates the use of multiple economic scenarios and the weighting of those scenarios on a quarterly basis. The scenarios that are chosen and the amount of weighting given to each scenario depend on a variety of factors including third party economists and firms, industry trends and other available published economic information.

    After the reasonable and supportable forecast period, the Company reverts to average historical losses. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by the Company.

    Also included in the allowance for loans are qualitative reserves to cover losses that are expected but, in the Company’s assessment, may not be adequately represented in the quantitative method or the economic assumptions described above. For example, factors that the Company considers include changes in lending policies and procedures, business conditions, the nature and size of the portfolio, portfolio concentrations, the volume and severity of past due loans and non-accrual loans, the effect of external factors such as competition, and the legal and regulatory requirements, among other. Furthermore, the Company considers the inherent uncertainty in quantitative models that are built on historical data.

Individually evaluated

    On a case-by-case basis, the Company may conclude a loan should be evaluated on an individual basis based on its disparate risk characteristics. The Company individually evaluates loans that meet the following criteria for expected credit loss, as the Company has determined that these loans generally do not share similar risk characteristics with other loans in the portfolio:

•Commercial loans with an outstanding balance greater than $1.0 million and on non-accrual status;

•Troubled debt restructured loans; and

•Other commercial loans with greater than $1.0 million in outstanding principal, if management has specific information that it is probable they will not collect all principal amounts due under the contractual terms of the loan agreement.

    When the Company determines that the loan no longer shares similar risk characteristics of other loans in the portfolio, the allowance will be determined on an individual basis using the present value of expected cash flows or, for collateral-dependent loans, the fair value of the collateral as of the reporting date, less estimated selling costs, as applicable, to ensure that the credit loss is not delayed until actual loss. If the fair value of the collateral is less than the amortized cost basis of the loan, the Company will charge off the difference between the fair value of the collateral, less costs to sell at the reporting date and the amortized cost basis of the loan.

Acquired assets

    Acquired assets are included in the Company's calculation of the allowance for credit losses. How the allowance on an acquired asset is recorded depends on whether it has been classified as a Purchased Financial Asset with Credit Deterioration (“PCD”). PCD assets are assets acquired at a discount that is due, in part, to credit quality. PCD assets are accounted for in accordance with ASC Subtopic 326-20 and are initially recorded at fair value as determined by the sum of the present value of expected future cash flows and an allowance for credit losses at acquisition. The allowance for PCD assets is recorded through a gross-up effect, while the allowance for acquired non-PCD assets such as loans is recorded through provision expense, consistent with originated loans. Thus, the determination of which assets are PCD and non-PCD can have a significant effect on the accounting for these assets.

    Subsequent to acquisition, the allowance for PCD loans will generally follow the same estimation, provision and

charge-off process as non-PCD acquired and originated loans. Additionally, TDR identification for acquired loans (PCD and non-PCD) will be consistent with the TDR identification for originated loans.

Allowance for Credit Losses on Debt Securities

    Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. Management classifies the held-to-maturity portfolio into the following major security types: mortgage-backed residential securities, municipal bonds, trust preferred securities (“TruPS”) and other. Nearly all of the mortgage-backed securities in the Company's portfolio are issued by U.S. government agencies and are either explicitly or implicitly guaranteed by the U.S government, are highly rated by major rating agencies and have a long history of no credit losses and therefore the expectation of non-payment is zero. Other securities consist primarily of investments in pooled trust preferred securities.

    At each reporting period, the Company evaluates whether the securities in a segment continue to exhibit similar risk characteristics as the other securities in the segment. If the risk characteristics of a security change, such that they are no longer similar to other securities in the segment, the Company will evaluate the security with a different segment that shares more similar risk characteristics.

    In estimating the net amount expected to be collected for mortgage-backed residential securities and municipal bonds, a range of historical losses method is utilized.  In estimating the net amount expected to be collected for TruPS, the Company employs a single scenario forecast methodology.  The scenario is informed by historical industry default data as well as current and near term operating conditions for the banks and other financial institutions that are the underlying issuers. In addition, prepayment assumptions are included in the analysis of the individually assessed TruPS applied at the collateral level.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures

     The Company is required to include the unfunded commitment that is expected to be funded in the future within the allowance calculation. The Company participates in lending that results in an off-balance sheet unfunded commitment balance. The Company currently underwrites funding commitments with conditionally cancelable language. To determine the expected funding balance remaining, the Company uses a historical utilization rate for each of the segments to calculate the expected commitment balance. The reserve percentage for each respective loan portfolio is applied to the remaining unused portion of the expected commitment balance and the expected funded commitment in determining the allowance for credit loss on off-balance sheet credit exposures.

Section 4013 of the CARES Act

    The Company implemented various consumer and commercial loan modification programs to provide its borrowers relief from the economic impacts of COVID-19. In accordance with the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), the Company elected to not apply troubled debt restructuring classification to any COVID-19 related loan modifications that occurred after March 1, 2020 to borrowers who were current as of December 31, 2019. Accordingly, these modifications are exempt from troubled debt restructuring classification under U.S. generally accepted accounting principles (“U.S. GAAP”) and were not classified as troubled debt restructurings (“TDRs”). In addition, for loans modified in response to the COVID-19 pandemic that did not meet the above criteria (e.g., current payment status at December 31, 2019), the Company applied the guidance included in an interagency statement issued by the bank regulatory agencies. This guidance states that loan modifications performed in light of the COVID-19 pandemic, including loan payment deferrals that are up to six months in duration, that were granted to borrowers who were current as of the implementation date of a loan modification program or modifications granted under government mandated modification programs, are not TDRs. For loan modifications that include a payment deferral and are not TDRs, the borrower’s past due and non-accrual status have not been impacted during the deferral period. The majority of our deferrals initially consisted of 90-day principal and interest deferrals with additional deferral periods granted on a case by case basis at the Bank’s option. Interest income has continued to be recognized over the contractual life of the loan. At September 30, 2020, loans with an aggregate outstanding balance of approximately $1.02 billion were in COVID-19 related deferment. For the nine months ended September 30, 2020, interest income on deferred loans totaled $44.3 million, of which $9.3 million was included in accrued interest receivable as of September 30, 2020.

Stock Repurchase Program

    On October 25, 2018, the Company announced its fourth share repurchase program, which authorized the purchase of 10% of its publicly-held outstanding shares of common stock, or 28,886,780 shares. The fourth program commenced immediately upon completion of the third program on December 10, 2018 and remains the Company’s current program as of September 30, 2020.

    During the nine months ended September 30, 2020, the Company purchased 390,712 shares at a cost of $3.4 million, or $8.75 per share. All shares purchased during the nine months ended September 30, 2020 were purchased in connection with the vesting of shares of restricted stock under our 2015 Equity Incentive Plan and the withholding of shares to pay income taxes. These shares are repurchased pursuant to the terms of the 2015 Equity Incentive Plan and therefore are not part of the Company’s repurchase program.Stockholders’ Equity

Gold Coast Bancorp    

    As of the close of business on April 3, 2020, the Company completed its acquisition of Gold Coast Bancorp (“Gold Coast”) pursuant to the Agreement and Plan of Merger, dated as of July 24, 2019 by and between the Company and Gold Coast. As a result of the completion of the acquisition, the Company issued approximately 2.8 million shares to the former stockholders of Gold Coast and paid approximately $31.0 million in cash to the former stockholders of Gold Coast. Under the terms of the merger agreement, 50% of the common shares of Gold Coast were converted into Investors Bancorp common stock and the remaining 50% was exchanged for cash. For each share of Gold Coast Bancorp common stock, Gold Coast shareholders were given an option to receive either (i) 1.422 shares of Investors Bancorp common stock, $0.01 par value per share, (ii) a cash payment of $15.75, or (iii) a combination of Investors Bancorp common stock and cash. The foregoing was subject to proration to ensure that, in the aggregate, 50% of Gold Coast’s shares would be converted into Investors Bancorp common stock.

    The acquisition was accounted for under the acquisition method of accounting as prescribed by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805 “Business Combinations”, as amended. Under this method of accounting, the purchase price has been allocated to the respective assets acquired based on their estimated fair values, net of applicable income tax effects. The excess cost over fair value of assets acquired, or $12.0 million, has been recorded as goodwill.

    The acquired portfolio was fair valued on the date of acquisition based on guidance from ASC 820-10 which defines fair value as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. The valuation methods utilized took into consideration adjustments for interest rate risk, funding cost, servicing cost, residual risk, credit and liquidity risk.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition for Gold Coast, net of cash consideration paid:

	At April 3, 2020
	(In millions)
Cash and cash equivalents	$	7.3
Debt securities available-for-sale	51.5
Debt securities held to maturity	8.4
Loans receivable, net	443.5
Accrued interest receivable	1.3
Right-of-use assets	3.7
Net deferred tax asset	3.9
Intangible assets	14.5
Other assets	1.2
Total assets acquired	535.3
Deposits	489.9
Borrowed funds	14.9
Other liabilities	9.7
Total liabilities assumed	514.5
Net assets acquired	$	20.8

    As the Company finalizes its analysis of these assets, there may be adjustments to the recorded carrying values. Any adjustments to carrying values will be recorded in goodwill. The calculation of goodwill is subject to change for up to one year after closing date of the transaction as additional information relative to closing date estimates and uncertainties becomes available. For the three months ended September 30, 2020, there was no change to the amount of goodwill recorded for this acquisition.

    Financial assets acquired in a business combination after January 1, 2020 are recorded in accordance with ASC Topic 326, after which acquired assets are separated into two types. PCD assets are acquired assets that, as of the acquisition date, have experienced a more-than-insignificant deterioration in credit quality since origination. Non-PCD assets are acquired assets that have experienced no or insignificant deterioration in credit quality since origination. To distinguish between the two types of acquired assets, the Company evaluates risk characteristics that have been determined to be indicators of deteriorated credit quality. In the case of loans, the determining criteria may involve general characteristics, such as loan payment history or changes in creditworthiness since the loan was originated, while others are relevant to recent economic conditions, such as borrowers in industries impacted by the pandemic.

In its acquisition of Gold Coast, the Company has purchased loans which have been determined to be PCD. The carrying amount of those loans was as follows:

	At April 3, 2020
	(In millions)
Purchase price of loans at acquisition	$	244.7
Allowance for credit losses at acquisition	4.2
Non-credit discount (premium) at acquisition	2.6
Par value of acquired loans at acquisition	$	251.5

There were no PCD securities in the acquisition.

Fair Value Measurement of Assets Acquired and Liabilities Assumed

    Described below are the methods used to determine the fair values of the significant assets acquired and liabilities assumed in the Gold Coast acquisition based on guidance from ASC 820-10 which defines fair value as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date.

Securities. The securities acquired are bought and sold in active markets. The estimated fair values of securities were calculated using external third party broker opinions of the market values. Due to the instability of the market at the time of acquisition as well as the odd lot position sizes of the securities, the Company reviewed the data and assumptions used in pricing the securities by third-parties and made qualitative adjustments to reflect the odd lot size of the securities and the price that would be received in an orderly transaction.

Loans. The estimated fair values of the loan portfolio generally consider adjustments for interest rate risk, required funding costs, servicing costs, prepayments, credit and liquidity. Level 3 inputs were utilized to determine the fair value of the acquired loan portfolio and included the use of present value techniques employing cash flow estimates and incorporated assumptions that market participants would use in estimating fair values. In instances where reliable market information was not available, the Company used its own assumptions in an effort to determine fair value. The primary approach to determining the fair value of the loan portfolio was a discounted cash flow methodology that considered factors including the type of loan, underlying collateral, classification status or grade, interest rate structure (fixed or variable interest rate), and remaining term. For the non-credit component, loans were grouped together according to similar characteristics when applying the various valuations techniques. For the credit component, loans were also grouped based on whether they had more than insignificant deterioration in credit since origination (purchase credit deteriorated “PCD” as defined by ASC 326-20). The expected life of loan loss estimates were calculated based on an annual loss rate developed by using the historical annual average charge-off percentages for New York institutions as a proxy for how a market participant acquirer would value the portfolio. Additionally, a qualitative credit adjustment was applied to the historical annual loss rates, due to COVID-19 and the uncertainty of future losses.

Deposits / Core Deposit Intangible. The core deposit intangible represents the value assigned to the stable and below market rate funding sources within the acquired deposit base; typically demand deposits, interest checking, money market and savings accounts. The core deposit intangible value represents the value of the relationships with deposit customers as a below market rate funding source. The fair value was based on a discounted cash flow methodology that gave appropriate consideration to expected deposit attrition rates, net maintenance costs of the deposit base, projected interest costs and the alternative cost of funds. Certificates of deposit (time deposits) are not considered to be core deposits as they are less stable and do not have an “all-in” favorable funding advantage to the alternative cost of funds. The fair value of certificates of deposit represents the present value of the certificates’ expected contractual payments discounted by market rates for similar certificates and is determined utilizing Level 2 inputs.

Borrowed Funds. A discounted cash flow approach was used to determine the fair value of the debt acquired. The fair value of the liability represents the present value of the expected payments discounted using a risk adjusted discount rate. The discount rate was developed based on comparable rated securities, as that backed by companies with similar credit ratings as the Company.

(1) Net unrealized losses of held-to-maturity corporate and other debt securities represent the previously recorded other than temporary charge related to other non-credit factors and is being amortized through accumulated other comprehensive income over the remaining life of the securities. For mortgage-backed securities, it represents the net loss on previously designated available-for sale debt securities transferred to held-to-maturity at fair value and is being amortized through accumulated other comprehensive income over the remaining life of the securities.

(2) Unrecognized gains and losses of held-to-maturity debt securities are not reflected in the financial statements, as they represent fair value fluctuations from the later of: (i) the date a security is designated as held-to-maturity; or (ii) the date that an other than temporary impairment charge is recognized on a held-to-maturity security, through the date of the balance sheet. Effective January 1, 2020, held-to-maturity debt securities are evaluated for credit losses to determine if an allowance is necessary. Any allowance required is recorded through the provision for credit losses.

    We conduct periodic reviews of individual securities to assess whether an allowance for credit loss is required. Held-to-maturity debt securities are evaluated for expected credit loss utilizing a historical loss methodology, or a discounted cash flows approach which is assessed against the book value of the investment security excluding accrued interest. Refer to Note 1, Summary of Significant Accounting Principles, for additional information. Available-for-sale debt securities are evaluated to determine if a decline in fair value below the amortized cost basis has resulted from a credit loss or other factors. An impairment related to credit factors would be recorded through an allowance for credit losses. The allowance is limited to the amount by which the security’s amortized cost basis exceeds the fair value. An impairment that has not been recorded through an allowance for credit losses shall be recorded through other comprehensive income, net of applicable taxes. Investment securities will be written down to fair value through the consolidated statement of income when management intends to sell (or may be required to sell) the securities before they recover in value.

    The majority of our held-to-maturity debt securities portfolio is comprised of agency mortgage-backed securities. For agency (FNMA, FHLMC and GNMA) mortgage-backed securities, and other agency debt instruments, the expectation of non-payment is zero. The timely payment of principal and interest on FNMA and FHLMC securities is guaranteed by each corporation. As each of these corporations is in conservatorship with the federal government, the payment guarantees are considered implicit obligations of the US government. GNMA securities carry the full faith and credit guarantee of the federal government. Because of the existence of government guarantees of timely payment of principal and interest, expected losses on agency securities are assumed to be zero. Changes in the fair value of agency securities in this portfolio are primarily driven by changes in interest rates and other non-credit related factors. At September 30, 2020, our held-to-maturity debt securities portfolio had an allowance for credit losses of $3.1 million. The allowance is related to non-agency corporate and other debt securities. The majority of the allowance is related to a portfolio of collateralized debt obligations backed by pooled TruPS, principally issued by banks and to a lesser extent insurance companies and real estate investment trusts. At September 30, 2020, the TruPS had a carrying value before allowance for credit losses and estimated fair value of $49.3 million and $64.1 million, respectively. The Company does not have the intent to sell these securities and does not believe it is more likely than not that the Company will be required to sell these securities before a recovery of amortized cost.

    At September 30, 2020, the available-for-sale debt securities portfolio was almost entirely comprised of agency securities. As such, the unrealized losses in this portfolio are primarily driven by changes in interest rates and other non-credit related factors. The Company does not have the intent to sell these securities and does not believe it is more likely than not that the Company will be required to sell these securities before a recovery of amortized cost. As of September 30, 2020, there is no allowance for credit losses related to the Company’s available-for-sale debt securities as the decline in fair value did not result from credit issues.

    For additional information about the review of securities under previous other-than-temporary impairment guidance, refer to page 82 in Note 4 to the consolidated financial statements included under Item 15. Exhibits and Financial Statement Schedules in the Company’s December 31, 2019 Form 10-K.

    Debt securities with a carrying value before allowance for credit losses of $1.57 billion and an estimated fair value of $1.62 billion are pledged to secure borrowings and municipal deposits. The contractual maturities of the Bank’s mortgage-backed securities are generally less than 20 years with effective lives expected to be shorter due to prepayments. Expected maturities may differ from contractual maturities due to underlying loan prepayments or early call privileges of the issuer; therefore, mortgage-backed securities are not included in the following table. Excluding the allowance for credit losses, the amortized cost and estimated fair value of debt securities other than mortgage-backed securities at September 30, 2020, by contractual maturity, are shown below.

Gains and Losses

    Gains and losses on the sale of all securities are determined using the specific identification method. For the three and nine months ended September 30, 2020, there were no sales of securities; however, for the nine months ended September 30,

2020, the Company received proceeds of $16.5 million from the call of a held-to-maturity debt security which resulted in a gain of $124,000 and received a principal payment of $26,000 on a held-to-maturity debt security. The Company recognized net unrealized losses on equity securities of $8,000 and net unrealized gains of $99,000, respectively, for the three and nine months ended September 30, 2020.

    For the three months ended September 30, 2019, there were no sales of securities. For the nine months ended September 30, 2019, the Company received proceeds of $399.4 million on securities sold from the debt securities available-for-sale portfolio resulting in a loss of $5.7 million recognized in non-interest income. Proceeds from the sale were reinvested in higher yielding debt securities. There were no other sales of securities for the nine months ended September 30, 2019. The Company recognized net unrealized gains on equity securities of $30,000 and $165,000, respectively, for the three and nine months ended September 30, 2019.

Credit Quality Indicators

    The Company has lending policies and procedures that provide target market, underwriting and other criteria for identified lending segments to codify the level of credit risk the Company is willing to accept. Approval authority levels are delegated to qualified individuals and approval bodies for the extension of credit within the guidance of these policies and procedures. In addition, the Company maintains an independent loan review department that reviews and validates risk assessment on a continual basis.

    The Company assigns ratings to borrowers and transactions based on the assessment of a borrower’s ability to service their debt based on relevant information such as: current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors.

    In connection with the adoption of Topic 326 on January 1, 2020, the Company implemented new risk rating models for borrowers and transactions within its commercial loan portfolio. The risk rating methodology transitioned to a dual risk rating framework which bifurcates ratings into probability of default (PD) and loss given default (LGD). Relevant risks are evaluated prior to approving a transaction to determine if the transaction is within the Company’s risk appetite and the appropriate rating. Strong credit analysis requires current, reliable financial information and documented assessment of the customer’s:

•ability to perform in accordance with the terms of the credit, including adherence to covenants;

•assets and liabilities, liquidity, net worth, and contingent and other off-balance sheet items;

•tax liabilities;

•cash reserves and ability to convert assets to cash;

•income statement and the sources, level, stability, and quality of earnings:

•projected performance, sensitized for stressed circumstances; and

•industry performance relative to peers and industry.

    Each commercial credit facility is assigned a PD and LGD rating for the purpose of informing a credit decision, facilitating the determination of the expected level of credit loss and other portfolio management activities (as well as relationship profitability). The dual risk rating framework and risk rating methodologies allow for consistent determination of risk across the Commercial business as indicated by the risk rating assigned. The methodology used by the Bank applies the same criteria for identification of a credit as for the regulatory definitions of risk ratings:

Pass - “Pass” assets are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell, of any underlying collateral in a timely manner.

Watch - A “Watch” asset has all the characteristics of a Pass asset but warrants more than the normal level of supervision. These loans may require more detailed reporting to management because some aspects of underwriting may not conform to policy or adverse events may have affected or could affect the cash flow or ability to continue operating profitably, provided, however, the events do not constitute an undue credit risk. Residential and consumer loans delinquent 30-59 days are considered watch if not a troubled debt restructuring (“TDR”). In addition, any residential or consumer loan currently on deferment in accordance with the CARES Act or the interagency statement issued by bank regulatory agencies are considered watch.

Special Mention - A “Special Mention” asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. Residential and consumer loans delinquent 60-89 days are considered special mention if not a TDR.

Substandard - A “Substandard” asset is inadequately protected by the current worth and paying capacity of the obligor or by the collateral pledged, if any. Assets so classified must have a well-defined weakness, or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Residential and consumer loans delinquent 90 days or greater as well as TDRs are considered substandard.

Doubtful - An asset classified “Doubtful” has all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently known facts, conditions, and values.

Loss - An asset or portion thereof, classified “Loss” is considered uncollectible and of such little value that its continuance on the institution’s books as an asset, without establishment of a specific valuation allowance or charge-off, is not warranted. This classification does not necessarily mean that an asset has no recovery or salvage value; but rather, there is much doubt about whether, how much, or when the recovery will occur. As such, it is not practical or desirable to defer the write-off.

The following table presents the risk category of loans as of September 30, 2020 by class of loan and vintage year:

Delinquent and Non-Accrual Loans

In the absence of other intervening factors, loans granted payment deferrals related to COVID-19 are not reported as past due or placed on non-accrual status provided the borrowers have met the criteria in the CARES Act or otherwise have met the criteria included in an interagency statement issued by bank regulatory agencies. See Note 1, Summary of Significant Accounting Principles.

Individually Evaluated Loans

    Loans which do not share common risk characteristics with other loans are individually evaluated as part of the process of calculating the allowance for credit losses. The evaluation is determined on an individual basis using the present value of expected cash flows or the fair value of the collateral as of the reporting date. When management determines that the fair value of collateral securing a collateral dependent loan inadequately covers the balance of net principal, the net principal balance is written down to the fair value of the collateral, net of estimated selling costs as applicable, rather than assigning an allowance. See Note 16, Fair Value Measurements, for information regarding the valuation process for collateral dependent loans.

TDR Loans Included in Non-Accrual

Included in the non-accrual tables above are TDR loans whose payment status is current, but the Company has classified as non-accrual as the loans have not maintained their current payment status for six consecutive months under the restructured terms and therefore do not meet the criteria for accrual status. As of September 30, 2020 and December 31, 2019, these loans are comprised of the following:

	September 30, 2020			December 31, 2019
	# of loans	Amount		# of loans	Amount

    The Company has no loans past due 90 days or more delinquent that are still accruing interest.

Troubled Debt Restructurings    

    On a case-by-case basis, the Company may agree to modify the contractual terms of a borrower’s loan to remain competitive and assist customers who may be experiencing financial difficulty, as well as preserve the Company’s position in the loan. If the borrower is experiencing financial difficulties and a concession has been made at the time of such modification, the loan is classified as a TDR.

    Substantially all of our TDR loan modifications involve lowering 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, or a combination of these two methods. These modifications rarely result in the forgiveness of principal or accrued interest. In addition, we frequently obtain additional collateral or guarantor support when modifying commercial loans. Restructured loans remain on non-accrual status until there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible.

    Consistent with the CARES Act and interagency guidance which allows temporary relief for current borrowers affected by COVID-19, we are working with borrowers and granting certain modifications through programs related to

COVID-19 relief. At September 30, 2020, loans with an aggregate outstanding balance of approximately $1.02 billion have been granted modifications as a result of financial disruptions associated with the COVID-19 pandemic. Also, consistent with the CARES Act and the interagency guidelines, such modifications that met the criteria discussed in Note 1 are not included in our TDR totals and discussion below. For more information on the criteria for classifying loans as TDRs, see Note 1, Summary of Significant Accounting Principles - Section 4013 of the CARES Act.

    Post-modification recorded investment represents the net book balance immediately following modification.

    Collateral dependent loans classified as TDRs were written down to the estimated fair value of the collateral. There were no charge offs for TDRs during the three months ended September 30, 2020. There were $163,000 in charge-offs for a TDR of an unsecured commercial and industrial loan during the nine months ended September 30, 2020. There were $156,000 and $729,000 in charge-offs for TDRs of unsecured commercial and industrial loans during the three and nine months ended September 30, 2019, respectively. The allowance for loan losses associated with the TDRs presented in the above tables totaled $1.6 million and $1.8 million as of September 30, 2020 and December 31, 2019, respectively.

    Loan modifications generally involve the reduction in loan interest rate and/or extension of loan maturity dates and also may include step up interest rates in their modified terms which will impact their weighted average yield in the future. Prior to 2020, all residential loans deemed to be TDRs were modified to reflect a reduction in interest rates to current market rates. Residential loans modified in 2020 and deemed to be TDRs were granted a payment deferral related to COVID-19 but did not meet the criteria to be excluded from TDR as described in Note 1, Summary of Significant Accounting Principles - Section 4013 of the CARES Act. Two of the commercial loan modifications which qualified as a TDR in the nine months ended September 30, 2020 were loans which had already been on non-accrual status and were granted a deferral of payment due to circumstances related to COVID-19. Another commercial loan modification which qualified as a TDR in the first quarter of 2020 had its maturity extended. The commercial loan modifications which qualified as TDRs in the nine months ended September 30, 2019 had their maturity extended.

    The following tables present information about pre and post modification interest yield for TDRs which occurred during the three and nine months ended September 30, 2020 and 2019:

Allowance for Credit Losses

Credit Loss [Abstract]

Allowance for Credit Losses

Allowance for Credit Losses

    On January 1, 2020, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the CECL methodology. See Note 1, Summary of Significant Accounting Principles.

An analysis of the provision for credit losses is summarized as follows:

	Three Months Ended September 30,			Nine Months Ended September 30,
	2020		2019	2020	2019
	(In thousands)

    Accrued interest receivable on loans, reported as a component of accrued interest receivable on the balance sheet, totaled $74.3 million at September 30, 2020. For the period ended September 30, 2020, the Company recorded a provision for loan loss related to interest accrued on residential and consumer loans in payment deferral.

    The lifetime estimate considers multiple economic scenarios, including recessionary scenarios that assume deterioration in key economic variables such as gross domestic product, unemployment rate and real estate prices.  As of January 1, 2020, the Company’s economic outlook was weighted to include a moderate potential of a recession with some expectation of tail risk similar to the severely adverse scenario used in stress testing. During the nine months ended September 30, 2020, there was a significant change in the economic outlook impacting the allowance for credit losses, with key economic factors such as the unemployment rate and gross domestic product severely affected by the impact of COVID-19. For the three months ended September 30, 2020, there was improvement in the U.S. and global macroeconomic consensus outlooks, which resulted in an improvement in the economic outlook used to determine the allowance for credit losses when compared to June 30, 2020. In response to these changes, the Company continues to assess the selection and probability weightings of the economic scenarios.  Multiple economic outlooks were used for the September 30, 2020 estimate of the allowance for credit losses that included a base or consensus case, a downside recessionary case and an upside scenario to reflect the potential for continued improvement in the economic outlook.  In addition, the allowance for credit losses at September 30, 2020 included qualitative reserves for certain segments that may not be fully recognized through its quantitative models.  There are still many unknowns including the duration of the impact of COVID-19 on the economy and the results of the government fiscal and monetary actions along with recently implemented payment deferral programs, and the Company will continue to evaluate the allowance for credit losses and the related economic outlook each quarter.

    Mortgage servicing rights are accounted for using the amortization method. Under this method, the Company amortizes the loan servicing asset in proportion to, and over the period of, estimated net servicing revenues. The Company sells loans on a servicing-retained basis. Loans that were sold on this basis had an unpaid principal balance of $1.74 billion and $1.67 billion at September 30, 2020 and December 31, 2019, respectively, all of which relate to mortgage loans. At September 30, 2020 and December 31, 2019, the servicing asset, included in other intangible assets, had an estimated fair value of $11.2 million and $14.1 million, respectively. At September 30, 2020, fair value was based on expected future cash flows considering a weighted average discount rate of 12.03%, a weighted average constant prepayment rate on mortgages of 19.14%

and a weighted average life of 4.2 years. Based on an analysis of fair values as of September 30, 2020, the Company determined that a $1.5 million valuation allowance for mortgage servicing rights was required, a decrease of $1.2 million from the previous quarter. See Note 16 for additional details.

    Core deposit premiums are amortized using an accelerated method and having a weighted average amortization period of 10 years. For the nine months ended September 30, 2020, the Company recorded $2.5 million in core deposit premiums resulting from the acquisition of Gold Coast.

Leases [Abstract]

Leases

Leases

    The Company has operating leases for corporate offices, branch locations and certain equipment. For these operating leases, the Company recognizes 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. The Company’s leases have remaining lease terms of up to 16 years, some of which include options to extend the leases for up to 10 years, and some of which include options to terminate the leases within 1 year. Certain of our operating leases for branch locations contain variable lease payments related to consumer price index adjustments.

The following table presents the balance sheet information related to our operating leases:

	September 30, 2020			December 31, 2019
	(Dollars in thousands)
Operating lease right-of-use assets	$	171,781		175,143
Operating lease liabilities	184,281			185,827
Weighted average remaining lease term	9.0 years			9.7 years
Weighted average discount rate	2.66		%	2.74	%

    In determining the present value of lease payments, the discount rate used for each individual lease is the rate implicit in the lease, unless that rate cannot be readily determined, in which case the Company is required to use its incremental borrowing rate based on the information available at commencement date. For its incremental borrowing rate, the Company uses the borrowing rates offered to the Company by the Federal Home Loan Bank, which reflects the rates a lender would charge the Company to obtain a collateralized loan.

The following table presents the components of total operating lease cost recognized in the Consolidated Statements of Income:

Share-based Payment Arrangement [Abstract]

Equity Incentive Plan

Equity Incentive Plan

    At the annual meeting held on June 9, 2015, stockholders of the Company approved the Investors Bancorp, Inc. 2015 Equity Incentive Plan (“2015 Plan”) which provides for the issuance or delivery of up to 30,881,296 shares (13,234,841 restricted stock awards and 17,646,455 stock options) of Investors Bancorp, Inc. common stock.

    Restricted shares granted under the 2015 Plan vest in equal installments, over the service period generally ranging from 5 to 7 years beginning one year from the date of grant. Additionally, certain restricted shares awarded are performance vesting awards, which may or may not vest depending upon the attainment of certain corporate financial targets. The vesting of restricted stock may accelerate in accordance with the terms of the 2015 Plan. The product of the number of shares granted and the grant date closing market price of the Company’s common stock determine the fair value of restricted shares under the 2015 Plan. Management recognizes compensation expense for the fair value of restricted shares on a straight-line basis over the requisite service period. For the nine months ended September 30, 2020 and September 30, 2019, the Company granted 90,067 and 2,345,919 shares of restricted stock awards under the 2015 Plan, respectively.

    Stock options granted under the 2015 Plan vest in equal installments, over the service period generally ranging from 5 to 7 years beginning one year from the date of grant. The vesting of stock options may accelerate in accordance with the terms of the 2015 Plan. Stock options were granted at an exercise price equal to the fair value of the Company’s common stock on the grant date based on the closing market price and have an expiration period of 10 years. For the nine months ended September 30, 2020 and September 30, 2019, the Company granted no stock options and 995,216 stock options under the 2015 Plan, respectively.

    The fair value of stock options granted as part of the 2015 Plan was estimated utilizing the Black-Scholes option pricing model using the following assumptions for the periods presented below:

	Nine Months Ended September 30,
	2019
Weighted average expected life (in years)	4.83
Weighted average risk-free rate of return	1.86		%
Weighted average volatility	19.92		%
Dividend yield	3.96		%
Weighted average fair value of options granted	$	0.89
Total stock options granted	995,216

    The weighted average expected life of the stock option represents the period of time that stock options are expected to be outstanding and is estimated using historical data of stock option exercises and forfeitures. The risk-free interest rate is

based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility is based on the historical volatility of the Company’s stock. The Company recognizes compensation expense for the fair values of these awards, which have graded vesting, on a straight-line basis over the requisite service period of the awards. Upon exercise of vested options, management expects to draw on treasury stock as the source for shares.

    The following table presents the share-based compensation expense for the three and nine months ended September 30, 2020 and 2019:

	Three Months Ended September 30,			Nine Months Ended September 30,
	2020		2019	2020	2019

Stock option expense	$	941	2,285	2,940	4,937
Restricted stock expense	2,539		4,026	8,383	10,933
Total share-based compensation expense (1)	$	3,480	6,311	11,323	15,870

(1) Included in share-based compensation expense for the three months and nine months ended September 30, 2019 was $2.0 million of accelerated stock compensation expense resulting from the settlement of shareholder litigation during the third quarter of 2019. There was no incremental expense resulting from the modification of the original awards associated with the settlement. For additional information about the settlement, refer to page 105 in Note 12 to the consolidated financial statements included under Item 15. Exhibits and Financial Statement Schedules in the Company’s December 31, 2019 Form 10-K.

    The following is a summary of the Company’s stock option activity and related information for the nine months ended September 30, 2020:

	Number of Stock Options	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in years)	Aggregate Intrinsic Value

Net Periodic Benefit Plan Expense

9 Months Ended

Sep. 30, 2020

Retirement Benefits [Abstract]

Net Periodic Benefit Plan Expense

Net Periodic Benefit Plan Expense    The Company has an Executive Supplemental Retirement Wage Replacement Plan (“SERP II”) and the Supplemental ESOP and Retirement Plan (“SERP I”) (collectively, the “SERPs”). The SERP II is a nonqualified, defined benefit plan which provides benefits to certain executives as designated by the Compensation and Benefits Committee of the Board of Directors. More specifically, the SERP II was designed to provide participants with a normal retirement benefit equal to an annual benefit of 60% of the participant’s highest annual base salary and cash incentive (over a consecutive 36-month period within the

participant’s credited service period) reduced by the sum of the benefits provided under the Pentegra Defined Benefit Plan for Financial Institutions (“Pentegra DB Plan”) and the SERP I. Effective as of the close of business of December 31, 2016, the SERP II was amended to freeze future benefit accruals subsequent to the 2016 year of service.

    The SERP I compensates certain executives (as designated by the Compensation and Benefits Committee of the Board of Directors) participating in the ESOP whose contributions are limited by the Internal Revenue Code. The Company also maintains the Amended and Restated Director Retirement Plan (“Directors’ Plan”) for certain directors, which is a nonqualified, defined benefit plan. The Directors’ Plan was frozen on November 21, 2006 such that no new benefits accrued under, and no new directors were eligible to participate in the plan. The SERPs and the Directors’ Plan are unfunded and the costs of the plans are recognized over the period that services are provided.

The components of net periodic benefit cost for the Directors’ Plan and the SERP II are as follows:

	Three Months Ended September 30,			Nine Months Ended September 30,
	2020		2019	2020	2019
	(In thousands)
Interest cost	$	325	397	973	1,191
Amortization of:
Net loss	298		—	896	—
Total net periodic benefit cost	$	623	397	1,869	1,191

    Due to the unfunded nature of the SERPs and the Directors’ Plan, no contributions have been made or were expected to be made during the nine months ended September 30, 2020.

    The Company also maintains the Pentegra DB Plan. As of December 31, 2016, the annual benefit provided under the Pentegra DB plan was frozen by an amendment to the plan. Freezing the plan eliminates all future benefit accruals and each participant’s frozen accrued benefit was determined as of December 31, 2016 and no further benefits will accrue beyond such date. Since it is a multi-employer plan, costs of the pension plan are based on contributions required to be made to the pension plan. There was no contribution required during the nine months ended September 30, 2020. We anticipate contributing funds to the plan to meet any minimum funding requirements for the remainder of 2020.

Derivatives and Hedging Activities

Sep. 30, 2020

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging Activities

Derivatives and Hedging Activities

    The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s floating rate borrowings and pools of fixed-rate assets.

Cash Flow Hedges of Interest Rate Risk

    The Company’s objectives in using interest rate derivatives are primarily to reduce cost and add stability to interest expense in an effort to manage its exposure to interest rate movements. Interest rate swaps designated as cash flow hedges involve the receipt of amounts subject to variability caused by changes in interest rates from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.  Changes in the fair value of derivatives designated and that qualify as cash flow hedges are initially recorded in other comprehensive income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Such derivatives were used to hedge the variability in cash flows associated with borrowings. The Company is hedging its exposure to the variability in future cash flows for forecasted transactions over a maximum period of fourteen months (excluding forecasted transactions related to the payment of variable interest on existing financial instruments).

    Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate borrowings. During the next twelve months, the Company estimates that an additional $46.7 million will be reclassified as an increase to interest expense.

Fair Value Hedges of Interest Rate Risk

    The Company is exposed to changes in the fair value of certain of its pools of fixed-rate assets due to changes in benchmark interest rates. The Company may use interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate. Interest rate swaps designated as fair value hedges involve the payment of fixed-rate amounts to a counterparty in exchange for the Company receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. Such derivatives were used to hedge the changes in fair value of certain of its pools of prepayable fixed-rate assets.

    For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in interest income.

    The Company terminated two interest rate swaps with an aggregate notional of $475.0 million during the nine months ended September 30, 2020. The Company terminated three interest rate swaps with an aggregate notional amount of $1.00 billion during the year ended December 31, 2019. The terminated swaps were due to mature in February 2020. There were no interest rate swaps designated as fair value hedges as of September 30, 2020.

Derivatives Not Designated as Hedges

    The Company has credit derivatives resulting from participation in interest rate swaps provided to external lenders as part of loan participation arrangements which are, therefore, not used to manage interest rate risk in the Company’s assets or liabilities. Additionally, the Company provides interest rate risk management services to commercial customers, primarily interest rate swaps. The Company’s market risk from unfavorable movements in interest rates related to these derivative contracts is economically hedged by concurrently entering into offsetting derivative contracts that have identical notional values, terms and indices.

    Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain lenders which participate in loans and commercial customers.

Stock Repurchase Program

    On October 25, 2018, the Company announced its fourth share repurchase program, which authorized the purchase of 10% of its publicly-held outstanding shares of common stock, or 28,886,780 shares. The fourth program commenced immediately upon completion of the third program on December 10, 2018 and remains the Company’s current program as of September 30, 2020.

    During the nine months ended September 30, 2020, the Company purchased 390,712 shares at a cost of $3.4 million, or $8.75 per share. All shares purchased during the nine months ended September 30, 2020 were purchased in connection with the vesting of shares of restricted stock under our 2015 Equity Incentive Plan and the withholding of shares to pay income taxes. These shares are repurchased pursuant to the terms of the 2015 Equity Incentive Plan and therefore are not part of the Company’s repurchase program.Stockholders’ Equity

Fair Value Measurements

9 Months Ended

Sep. 30, 2020

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

    We use fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Our debt securities available-for-sale and derivatives are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record at fair value other assets or liabilities on a non-recurring basis, such as held-to-maturity debt securities, mortgage servicing rights (“MSR”), loans receivable and other real estate owned. These non-recurring fair value adjustments involve the application of lower-of-cost-or-market accounting or write-downs of individual assets. Additionally, in connection with our mortgage banking activities we have commitments to fund loans held-for-sale and commitments to sell loans, which are considered free-standing derivative instruments, the fair values of which are not material to our financial condition or results of operations.

    In accordance with FASB ASC 820, “Fair Value Measurements and Disclosures”, we group our assets and liabilities at fair value in three levels, based on the markets in which the assets are traded and the reliability of the assumptions used to determine fair value. These levels are:

•Level 1 – Valuation is based upon quoted prices for identical instruments traded in active markets.

•Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market.

•Level 3 – Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include the use of option pricing models, discounted cash flow models and similar techniques. The results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset or liability.

    We base our fair values on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

Assets Measured at Fair Value on a Recurring Basis

Equity securities

    Our equity securities portfolio is carried at estimated fair value on a recurring basis, with any unrealized gains and losses recognized in the Consolidated Statements of Income. The fair values of equity securities are based on quoted market prices (Level 1).

Debt securities available-for-sale

    Our debt securities available-for-sale portfolio is carried at estimated fair value on a recurring basis, with any unrealized gains and losses, net of taxes, reported as accumulated other comprehensive income (loss) in stockholders’ equity. The fair values of debt securities available-for-sale are based upon quoted prices for similar instruments in active markets (Level 2). The pricing service may use quoted market prices of comparable instruments or discounted cash flow analyses, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in the valuation methodologies include, but are not limited to, benchmark yields, credit spreads, default rates, prepayment speeds and non-binding broker quotes. As the Company is responsible for the determination of fair value, it performs quarterly analyses 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 test 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 adjustment in the prices obtained from the pricing service.

Derivatives

    Derivatives are reported at fair value utilizing Level 2 inputs. The fair values of interest rate swap and risk participation agreements are based on a valuation model that uses primarily observable inputs, such as benchmark yield curves and interest rate spreads.

    The following tables provide the level of valuation assumptions used to determine the carrying value of our assets and liabilities measured at fair value on a recurring basis at September 30, 2020 and December 31, 2019.

    There have been no changes in the methodologies used at September 30, 2020 from December 31, 2019, and there were no transfers between Level 1 and Level 2 during the nine months ended September 30, 2020.

    There were no Level 3 assets measured at fair value on a recurring basis for the nine months ended September 30, 2020 and December 31, 2019.

Assets Measured at Fair Value on a Non-Recurring Basis

Mortgage Servicing Rights, Net

    Mortgage servicing rights are carried at the lower of cost or estimated fair value. The estimated fair value of MSR is obtained through independent third-party valuations through an analysis of future cash flows, incorporating assumptions market participants would use in determining fair value including market discount rates, prepayment 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.  At September 30, 2020, the fair value model used prepayment speeds ranging from 14.88% to 32.40% and a discount rate of 12.03% for the valuation of the mortgage servicing rights. At December 31, 2019, the fair value model used prepayment speeds ranging from 6.60% to 29.10% and a discount rate of 12.05% for the valuation of the mortgage servicing rights. 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 positive or negative effect on the fair value estimate.

Collateral-Dependent Loans/Impaired Loans Receivable

    With the adoption of ASU 2016-13, loans which meet certain criteria are individually evaluated as part of the process of calculating the allowance for credit losses. Prior to adoption, such loans were evaluated for impairment. However, the valuation method remains unchanged. A loan is individually evaluated when it is a commercial loan with an outstanding balance greater than $1.0 million and on non-accrual status, loans modified in a troubled debt restructuring, and other commercial loans with $1.0 million in outstanding principal if management has specific information that it is probable they will not collect all amounts due under the contractual terms of the loan agreement. Collateral-dependent loans secured by property are carried at the estimated fair value of the collateral less estimated selling costs. Estimated fair value is calculated using an independent third-party appraiser. In the event the most recent appraisal does not reflect the current market conditions due to the passage of time and other factors, management will obtain an updated appraisal or make downward adjustments to the existing appraised value based on their knowledge of the property, local real estate market conditions, recent real estate transactions, and for estimated selling costs, if applicable. Appraisals were generally discounted in a range of 0% to 25%. For non-collateral-dependent loans management estimates the fair value using discounted cash flows based on inputs that are largely unobservable and instead reflect management’s own estimates of the assumptions as a market participant would in pricing such loans.

Other Real Estate Owned and Other Repossessed Assets

    Other Real Estate Owned and Other Repossessed Assets are recorded at estimated fair value, less estimated selling costs when acquired, thus establishing a new cost basis. Fair value of foreclosed real estate property is generally based on independent appraisals. These appraisals include adjustments to comparable assets based on the appraisers’ market knowledge and experience and are discounted an additional 0% to 25% for estimated costs to sell. When an asset is acquired, the excess of the loan balance over fair value, less estimated selling costs, is charged to the allowance for loan losses. If further declines in the estimated fair value of the asset occur, a writedown is recorded through expense. The valuation of foreclosed and repossessed assets is subjective in nature and may be adjusted in the future because of changes in economic conditions. Operating costs after acquisition are generally expensed.

Loans Held for Sale

    Residential mortgage loans held for sale are recorded at the lower of cost or fair value and are therefore measured at fair value on a non-recurring basis. When available, the Company uses observable secondary market data, including pricing on recent closed market transactions for loans with similar characteristics.

    The following tables provide the level of valuation assumptions used to determine the carrying value of our assets measured at fair value on a non-recurring basis at September 30, 2020 and December 31, 2019. For the three months ended September 30, 2020, there was no change to the carrying value of collateral-dependent loans, other real estate owned or loans held for sale. For the three months ended December 31, 2019, there was no change to the carrying value of impaired loans or loans held for sale.

Other Fair Value Disclosures

    Fair value estimates, methods and assumptions for the Company’s financial instruments not recorded at fair value on a recurring or non-recurring basis are set forth below.

Cash and Cash Equivalents

    For cash, short-term U.S. Treasury securities and due from banks, the carrying amount approximates fair value.

Debt Securities Held-to-Maturity

    Our debt securities held-to-maturity portfolio, consisting primarily of mortgage-backed securities and other debt securities for which we have a positive intent and ability to hold to maturity, is carried at amortized cost less any allowance for credit losses. Management utilizes various inputs to determine the fair value of the portfolio. The Company obtains one price for each security primarily from a third-party pricing service, which generally uses quoted or other observable inputs for the determination of fair value. The pricing service normally derives the security prices through recently reported trades for identical or similar securities, making adjustments through the reporting date based upon available observable market information. For securities not actively traded, the pricing service may use quoted market prices of comparable instruments or discounted cash flow analyses, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in the valuation methodologies include, but are not limited to, benchmark yields, credit spreads, default rates, prepayment speeds and non-binding broker quotes. In the absence of quoted prices and in an illiquid market, valuation techniques, which require inputs that are both significant to the fair value measurement and unobservable, are used to determine fair value of the investment. Valuation techniques are based on various assumptions, including, but not limited to forecasted cash flows, discount rates, rate of return, adjustments for nonperformance and liquidity, and liquidation values. As the Company is responsible for the determination of fair value, it performs quarterly analyses 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 test 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 adjustment in the prices obtained from the pricing service.

FHLB Stock

    The fair value of the Federal Home Loan Bank of New York (“FHLB”) stock is its carrying value, since this is the amount for which it could be redeemed. There is no active market for this stock and the Bank is required to hold a minimum investment based upon the balance of mortgage related assets held by the member and or FHLB advances outstanding.

Loans

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

    The fair value estimates are made at a specific point in time based on relevant market information. They do not reflect any premium or discount that could result from offering for sale a particular financial instrument. Fair value estimates are based on judgments regarding future expected loss experience, risk characteristics and economic conditions. These estimates are subjective, involve uncertainties, and cannot be determined with precision.

Deposit Liabilities

    The fair value of deposits with no stated maturity, such as savings, checking accounts and money market accounts, is equal to the amount payable on demand. The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates which approximate currently offered for deposits of similar remaining maturities.

Borrowings

    The fair value of borrowings are based on securities dealers’ estimated fair values, when available, or estimated using discounted contractual cash flows using rates which approximate the rates offered for borrowings of similar remaining maturities.

Commitments to Extend Credit

    The fair value of commitments to extend credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For commitments to originate fixed rate loans, fair value also considers the difference between current levels of interest rates and the committed rates. Due to the short-term nature of our outstanding commitments, the fair values of these commitments are immaterial to our financial condition.

The carrying values and estimated fair values of the Company’s financial instruments are presented in the following table.

Limitations

    Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a 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 that are not considered financial assets include deferred tax assets, premises and equipment and bank owned life insurance. Liabilities for pension and other postretirement benefits are not considered financial liabilities. 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.

Standard	Description	Required date of adoption	Effect on Consolidated Financial Statements
Standards Adopted in 2020
Measurement of Credit Losses on Financial Instruments	This ASU changes how entities report credit losses for financial assets held at amortized cost and available-for-sale debt securities. The amendments replace the “incurred loss” approach with a methodology that incorporates macroeconomic forecast assumptions and management judgments applicable to and through the expected life of the portfolios based on relevant information about past events, including historical loss experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. The amendments apply to financial assets such as loans, leases and held-to-maturity investments; and certain off-balance sheet credit exposures. The amendments expand credit quality disclosure requirements.	January 1, 2020	The Company adopted the standard’s provisions and all of its related updates on January 1, 2020. The amendments were applied on a modified retrospective basis. See Note 1 - Summary of Significant Accounting Principles for information on the impact of the adoption of ASU 2016-13 on the Company’s Consolidated Financial Statements.
Intangibles-Goodwill and Other- Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force)	This new guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Specifically, where a cloud computing arrangement includes a license to internal-use software, the software license is accounted for by the customer in accordance with Subtopic 350-40, “Intangibles- Goodwill and Other-Internal-Use Software”.	January 1, 2020 Early adoption permitted	The Company will apply the amendments in this Update prospectively to all implementation costs incurred after January 1, 2020. The adoption of ASU No. 2018-15 did not have an impact on the Company’s Consolidated Financial Statements.
Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement	The amendments remove the requirement to disclose the amount of, and reasons for, transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of such transfers and the valuation processes for Level 3 fair value measurements. The ASU modifies the disclosure requirements for investments in certain entities that calculate net asset value and clarify the purpose of the measurement uncertainty disclosure. The ASU adds disclosure requirements about the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements.	January 1, 2020 Early adoption permitted to any removed or modified disclosures and delay of adoption of additional disclosures until the effective date	Changes should be applied retrospectively to all periods presented upon the effective date with the exception of the following, which should be applied prospectively: disclosures relating to changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the disclosures for uncertainty measurement. The adoption of ASU 2018-13 did not have an impact on the Company’s Consolidated Financial Statements.

Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment	This ASU simplifies subsequent measurement of goodwill by eliminating Step 2 of the impairment test while retaining the option to perform the qualitative assessment for a reporting unit to determine whether the quantitative impairment test is necessary. The ASU also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units.	January 1, 2020 Early adoption permitted for interim or annual goodwill impairment testing dates beginning after January 1, 2017	The Company is applying the amendments in ASU 2017-04 prospectively for goodwill impairment testing conducted after January 1, 2020.

Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity	The amendments simplify the accounting for certain financial instruments with the characteristics of liabilities and equity by reducing the number of models for convertible debt instruments and convertible preferred stock and amends how convertible instruments and equity contracts with an option to be settled in cash or shares affect the EPS calculation. The update also amends the derivatives scope exception for contracts in an entity’s own equity.	January 1, 2022 Early adoption permitted not earlier than fiscal years beginning 2021	The update is not expected to have a material impact on the Company’s Consolidated Financial Statements.
Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting	The amendments provide expedients and exceptions for applying GAAP to contracts or hedging relationships affected by the discontinuance of LIBOR as a benchmark rate to alleviate the burden and cost of such modifications. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments also provide a one-time election to sell and/or transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform.	Effective for a limited time as of March 12, 2020 through December 31, 2022	The Company is evaluating its financial instruments indexed to USD-LIBOR for which the amendments provide expedients and administrative relief.
Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force)	This update clarifies the application of the alternative provided in ASU 2016-01 to measure certain equity securities without a readily determinable fair value. The amendments in this update clarify that a company should consider observable transactions that require it to either apply or discontinue the equity method of accounting under Topic 323 for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments further provide clarification related to the accounting for certain forward contracts and purchased options.	January 1, 2021 Early adoption permitted	The update is to be applied prospectively. The Company does not expect ASU 2020-01 to have a material impact on its Consolidated Financial Statements.

Adoption of New Accounting Standards

Adoption of New Accounting Standards

    On January 1, 2020, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The Company adopted ASU 2016-13 using a modified retrospective approach. Results for reporting periods beginning after January 1, 2020 are presented under Topic 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP. At adoption, the Company increased its allowance for credit losses by $11.7 million, comprised of $12.7 million and $2.6 million, respectively, for unfunded commitments and held-to-maturity debt securities, partially offset by a decrease of $3.6 million for loans. Upon adoption the Company recorded a cumulative effect adjustment that reduced stockholders’ equity by $8.5 million, net of tax.

Allowance for Credit Losses

Allowance for Credit Losses    

    The allowance for credit losses includes both the allowance for loan and lease losses and the reserve for unfunded lending commitments and represents the estimated amount considered necessary to cover lifetime expected credit losses inherent in financial assets at the balance sheet date. The measurement of expected credit losses is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures such as loan commitments and unused lines of credit. The allowance is established through the provision for credit losses that is charged against income. The methodology for determining the allowance for credit losses is considered a critical accounting policy by management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment that could result in changes to the amount of the recorded allowance for credit losses. The allowance for loan and security losses is reported separately as contra-assets to loans and securities on the consolidated balance sheet. The expected credit loss for unfunded lending commitments and unfunded loan commitments is reported on the consolidated balance sheet in other liabilities. The provision for credit losses related to loans, unfunded commitments and debt securities is reported on the consolidated statement of income.

Allowance for Credit Losses on Loans Receivable

    The allowance for credit losses on loans is deducted from the amortized cost basis of the loan to present the net amount expected to be collected. Expected losses are evaluated and calculated on a collective basis for those loans which share similar risk characteristics. At each reporting period, the Company evaluates whether the loans in a pool continue to exhibit similar risk characteristics as the other loans in the pool. If the risk characteristics of a loan change, such that they are no longer similar to other loans in the pool, the Company will evaluate the loan with a different pool of loans that share similar risk characteristics. If the loan does not share risk characteristics with other loans, the Company will evaluate the allowance on an individual basis. The Company evaluates the segmentation at least annually to determine whether loans continue to share similar risk characteristics. Loans are charged off against the allowance when the Company believes the loan balances become uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged off or expected to be charged off.

    The Company has chosen to segment its portfolio consistent with the manner in which it manages the risk of the type of credit. The Company’s segments for loans include multi-family, commercial real estate, commercial and industrial, construction, residential and consumer.

    The Company calculates estimated credit loss on its loan portfolio typically using a probability of default and loss given default quantitative model methodology. The point in time probability of default and loss given default are then conditioned by macroeconomic scenarios to incorporate reasonable and supportable forecasts that affect the collectability of the reported amount. For a small portion of the loan portfolio, i.e. unsecured consumer loans, small business loans and loans to individuals, the Company utilizes a loss rate method to calculate the expected credit loss of that asset segment.

    The Company estimates the allowance for credit losses on loans using relevant available information from internal and external sources related to past events and current conditions as well as the incorporation of reasonable and supportable forecasts. The Company evaluates the use of multiple economic scenarios and the weighting of those scenarios on a quarterly basis. The scenarios that are chosen and the amount of weighting given to each scenario depend on a variety of factors including third party economists and firms, industry trends and other available published economic information.

    After the reasonable and supportable forecast period, the Company reverts to average historical losses. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by the Company.

    Also included in the allowance for loans are qualitative reserves to cover losses that are expected but, in the Company’s assessment, may not be adequately represented in the quantitative method or the economic assumptions described above. For example, factors that the Company considers include changes in lending policies and procedures, business conditions, the nature and size of the portfolio, portfolio concentrations, the volume and severity of past due loans and non-accrual loans, the effect of external factors such as competition, and the legal and regulatory requirements, among other. Furthermore, the Company considers the inherent uncertainty in quantitative models that are built on historical data.

Individually evaluated

    On a case-by-case basis, the Company may conclude a loan should be evaluated on an individual basis based on its disparate risk characteristics. The Company individually evaluates loans that meet the following criteria for expected credit loss, as the Company has determined that these loans generally do not share similar risk characteristics with other loans in the portfolio:

•Commercial loans with an outstanding balance greater than $1.0 million and on non-accrual status;

•Troubled debt restructured loans; and

•Other commercial loans with greater than $1.0 million in outstanding principal, if management has specific information that it is probable they will not collect all principal amounts due under the contractual terms of the loan agreement.

    When the Company determines that the loan no longer shares similar risk characteristics of other loans in the portfolio, the allowance will be determined on an individual basis using the present value of expected cash flows or, for collateral-dependent loans, the fair value of the collateral as of the reporting date, less estimated selling costs, as applicable, to ensure that the credit loss is not delayed until actual loss. If the fair value of the collateral is less than the amortized cost basis of the loan, the Company will charge off the difference between the fair value of the collateral, less costs to sell at the reporting date and the amortized cost basis of the loan.

Acquired assets

    Acquired assets are included in the Company's calculation of the allowance for credit losses. How the allowance on an acquired asset is recorded depends on whether it has been classified as a Purchased Financial Asset with Credit Deterioration (“PCD”). PCD assets are assets acquired at a discount that is due, in part, to credit quality. PCD assets are accounted for in accordance with ASC Subtopic 326-20 and are initially recorded at fair value as determined by the sum of the present value of expected future cash flows and an allowance for credit losses at acquisition. The allowance for PCD assets is recorded through a gross-up effect, while the allowance for acquired non-PCD assets such as loans is recorded through provision expense, consistent with originated loans. Thus, the determination of which assets are PCD and non-PCD can have a significant effect on the accounting for these assets.

    Subsequent to acquisition, the allowance for PCD loans will generally follow the same estimation, provision and

charge-off process as non-PCD acquired and originated loans. Additionally, TDR identification for acquired loans (PCD and non-PCD) will be consistent with the TDR identification for originated loans.

Allowance for Credit Losses on Debt Securities

    Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. Management classifies the held-to-maturity portfolio into the following major security types: mortgage-backed residential securities, municipal bonds, trust preferred securities (“TruPS”) and other. Nearly all of the mortgage-backed securities in the Company's portfolio are issued by U.S. government agencies and are either explicitly or implicitly guaranteed by the U.S government, are highly rated by major rating agencies and have a long history of no credit losses and therefore the expectation of non-payment is zero. Other securities consist primarily of investments in pooled trust preferred securities.

    At each reporting period, the Company evaluates whether the securities in a segment continue to exhibit similar risk characteristics as the other securities in the segment. If the risk characteristics of a security change, such that they are no longer similar to other securities in the segment, the Company will evaluate the security with a different segment that shares more similar risk characteristics.

    In estimating the net amount expected to be collected for mortgage-backed residential securities and municipal bonds, a range of historical losses method is utilized.  In estimating the net amount expected to be collected for TruPS, the Company employs a single scenario forecast methodology.  The scenario is informed by historical industry default data as well as current and near term operating conditions for the banks and other financial institutions that are the underlying issuers. In addition, prepayment assumptions are included in the analysis of the individually assessed TruPS applied at the collateral level.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures

     The Company is required to include the unfunded commitment that is expected to be funded in the future within the allowance calculation. The Company participates in lending that results in an off-balance sheet unfunded commitment balance. The Company currently underwrites funding commitments with conditionally cancelable language. To determine the expected funding balance remaining, the Company uses a historical utilization rate for each of the segments to calculate the expected commitment balance. The reserve percentage for each respective loan portfolio is applied to the remaining unused portion of the expected commitment balance and the expected funded commitment in determining the allowance for credit loss on off-balance sheet credit exposures.

Section 4013 of the CARES Act

    The Company implemented various consumer and commercial loan modification programs to provide its borrowers relief from the economic impacts of COVID-19. In accordance with the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), the Company elected to not apply troubled debt restructuring classification to any COVID-19 related loan modifications that occurred after March 1, 2020 to borrowers who were current as of December 31, 2019. Accordingly, these modifications are exempt from troubled debt restructuring classification under U.S. generally accepted accounting principles (“U.S. GAAP”) and were not classified as troubled debt restructurings (“TDRs”). In addition, for loans modified in response to the COVID-19 pandemic that did not meet the above criteria (e.g., current payment status at December 31, 2019), the Company applied the guidance included in an interagency statement issued by the bank regulatory agencies. This guidance states that loan modifications performed in light of the COVID-19 pandemic, including loan payment deferrals that are up to six months in duration, that were granted to borrowers who were current as of the implementation date of a loan modification program or modifications granted under government mandated modification programs, are not TDRs. For loan modifications that include a payment deferral and are not TDRs, the borrower’s past due and non-accrual status have not been impacted during the deferral period. The majority of our deferrals initially consisted of 90-day principal and interest deferrals with additional deferral periods granted on a case by case basis at the Bank’s option. Interest income has continued to be recognized over the contractual life of the loan. At September 30, 2020, loans with an aggregate outstanding balance of approximately $1.02 billion were in COVID-19 related deferment. For the nine months ended September 30, 2020, interest income on deferred loans totaled $44.3 million, of which $9.3 million was included in accrued interest receivable as of September 30, 2020.
