Notes to Consolidated Financial Statements

(Unaudited)

(1)      Organization

Territorial Bancorp Inc. is a Maryland corporation and is the holding company for Territorial Savings Bank. Territorial Savings Bank is a Hawaii state-chartered bank headquartered in Honolulu, Hawaii and is a member of the Federal Reserve System. Territorial Savings Bank has two inactive subsidiaries, Territorial Real Estate Co., Inc. and Territorial Financial Services, Inc.

(2)      Basis of Presentation

The accompanying unaudited consolidated financial statements of Territorial Bancorp Inc. have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited interim condensed consolidated financial statements and notes should be read in conjunction with the Company’s consolidated financial statements and notes thereto filed as part of the Annual Report on Form 10-K for the year ended December 31, 2020. In the opinion of management, all adjustments necessary for a fair presentation have been made and consist only of normal recurring adjustments. Interim results of operations are not necessarily indicative of results to be expected for the year. 

.

(3)      Recently Issued Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (FASB) amended various sections of the FASB Accounting Standards Codification (ASC) related to the accounting for credit losses on financial instruments. The amendment changes the threshold for recognizing losses from a “probable” to an “expected” model. The new model is referred to as the current expected credit loss model and applies to loans, leases, held-to-maturity investments, loan commitments and financial guarantees. The amendment requires the measurement of all expected credit losses for financial assets as of the reporting date (including historical experience, current conditions and reasonable and supportable forecasts) and enhanced disclosures that will help financial statement users understand the estimates and judgments used in estimating credit losses and evaluating the credit quality of an organization’s portfolio. The amendment is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In November 2019, the FASB issued an update that delays the effective date of the amendment for smaller reporting companies, as defined by the Securities and Exchange Commission, to fiscal years beginning after December 15, 2022. The Company is a smaller reporting company. The Company will apply the amendment’s provisions as a cumulative-effect adjustment to retained earnings at the beginning of the first period the amendment is effective. The Company has formed a team that is working on an implementation plan to adopt the amendment. The implementation plan will include developing policies, procedures and internal controls over the model. The Company is also working with a software vendor to measure expected losses required by the amendment. The Company is currently evaluating the effects that the adoption of this amendment will have on its consolidated financial statements and expects that the portfolio composition and economic conditions at the time of adoption will influence the accounting adjustment made at the time the amendment is adopted.

The Coronavirus Aid, Relief, and Economic Security (CARES) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act provides relief to financial institutions from categorizing eligible loan modifications as troubled debt restructurings over the remaining life of the modified loan. Eligible loan modifications under the CARES Act must be related to the COVID-19 pandemic and the borrower must not have been more than 30 days past due as of December 31, 2019. Loan modifications under the CARES Act must be executed during the period from March 1, 2020 to the earlier of December 31, 2020 or 60 days after the end of the national emergency. On December 21, 2020, legislation extended the troubled debt restructuring relief provisions of the CARES Act to January

8

1, 2022. Banking regulators issued similar guidance, which also clarified that a COVID-19 loan modification should not be considered a troubled debt restructuring if the borrower was not more than 30 days past due on payments at the time the loan modification program was implemented and the modification is considered short-term (not to exceed six months).

During the three months ended March 31, 2021 and 2020, the Company sold $4.8 million and $729,000, respectively, of held-to-maturity mortgage-backed securities and recorded gains of $420,000 and $28,000, respectively. The sale of the mortgage-backed securities, for which the Company had already collected a substantial portion of the outstanding purchased principal (at least 85%), were in accordance with the Investments – Debt and Equity Securities topic of the FASB ASC and do not taint management’s assertion of its intent to hold the remaining securities in the held-to-maturity portfolio to maturity.

During the three months ended March 31, 2021 and 2020, the Company sold $943,000 and $1.7 million, respectively, of available-for-sale mortgage-backed securities and recorded gains of $106,000 and $150,000, respectively.

Investment securities with amortized costs of $170.5 million and $192.7 million at March 31, 2021 and December 31, 2020, respectively, were pledged to secure deposits made by state and local governments, securities sold under agreements to repurchase and transaction clearing accounts.

Provided below is a summary of investment securities which were in an unrealized loss position at March 31, 2021 and December 31, 2020. The Company does not intend to sell held-to-maturity and available-for-sale securities

10

until such time as the value recovers or the securities mature and it is not more likely than not that the Company will be required to sell the securities prior to recovery of value or the securities mature.

Mortgage-Backed Securities. The unrealized losses on the Company’s investment in mortgage-backed securities were caused by increases in market interest rates subsequent to purchase. All of the mortgage-backed securities are guaranteed by Freddie Mac or Fannie Mae, which are U.S. government-sponsored enterprises, or Ginnie Mae, which is a U.S. government agency. Since the decline in market value is attributable to changes in interest rates and not credit quality, and the Company does not intend to sell these investments until maturity and it is not more likely than not that the Company will be required to sell such investments prior to recovery of its cost basis, the Company does not consider these investments to be other-than-temporarily impaired as of March 31, 2021 or December 31, 2020.

During the three months ended March 31, 2020, the Company securitized fixed-rate first mortgage loans with a book value of $9.4 million into Freddie Mac mortgage-backed securities to increase liquidity. The securitization transaction increased investment securities and lowered loans receivable. The securitization transaction was accounted for by recording the mortgage-backed securities at a fair value of $9.8 million. A net gain of $377,000 was recognized on the securitization transaction and recorded in gain on sale of loans in the Consolidated Statements of Income. There were no securitization transactions during the three months ended March 31, 2021.

Management considers the allowance for loan losses at March 31, 2021 to be at an appropriate level to provide for probable losses that can be reasonably estimated based on general and specific conditions at that date. While the Company uses the best information it has available to make evaluations, future adjustments to the allowance may be necessary if conditions differ substantially from the information used in making the evaluations. To the extent actual outcomes differ from the estimates, additional provisions for credit losses may be required that would reduce future earnings. In addition, as an integral part of their examination process, the bank regulators periodically review the allowance for loan losses and may require the Company to increase the allowance based on their analysis of information available at the time of their examination.

There were no loans individually evaluated for impairment with a related allowance for loan loss as of March 31, 2021 or December 31, 2020. Loans individually evaluated for impairment do not have an allocated allowance for loan loss because they are written down to fair value at the time of impairment.

The Company had 11 nonaccrual loans with a book value of $4.2 million as of March 31, 2021 and 12 nonaccrual loans with a book value of $4.4 million as of December 31, 2020. The Company collected interest on nonaccrual loans of $42,000 and $17,000 during the three months ended March 31, 2021 and 2020, respectively, but due to accounting and regulatory requirements, the Company recorded the interest as a reduction of principal. The Company would have recognized additional interest income of $94,000 and $15,000 during the three months ended March 31, 2021 and 2020, respectively, had the loans been accruing interest. The Company did not have any loans 90 days or more past due and still accruing interest as of March 31, 2021 and December 31, 2020.

The table below presents the aging of loans and accrual status by class of loans, net of unearned fees and discounts.

The Company primarily uses the aging of loans and accrual status to monitor the credit quality of its loan portfolio. When a mortgage loan becomes seriously delinquent (90 days or more contractually past due), it displays weaknesses that may result in a loss. As a loan becomes more delinquent, the likelihood of the borrower repaying the loan decreases and the loan becomes more collateral-dependent. A mortgage loan becomes collateral-dependent when the proceeds for repayment can be expected to come only from the sale or operation of the collateral and not from borrower repayments. Generally, appraisals are obtained after a loan becomes collateral-dependent or is four months delinquent. The carrying value of collateral-dependent loans is adjusted to the fair value of the collateral less selling costs. Any commercial real estate, commercial, construction or equity loan that has a loan balance in excess of a specified amount is also periodically reviewed to determine whether the loan exhibits any weaknesses and is performing in accordance with its contractual terms.

There were no loans modified in a troubled debt restructuring during the three months ended March 31, 2021 or 2020. There were no new troubled debt restructurings within the three months ended March 31, 2021 or 2020 that subsequently defaulted. Loan modifications under the CARES Act and the Interagency Statements issued by bank regulators in 2020 are discussed below.

15

The table below summarizes outstanding troubled debt restructurings by class of loans:

	Number of		Accrual		Number of		Nonaccrual
(Dollars in thousands)	Loans		Status		Loans		Status		Total
March 31, 2021:
One- to four-family residential mortgages		3	$	561		2	$	453	$	1,014
Total		3	$	561		2	$	453	$	1,014
December 31, 2020:
One- to four-family residential mortgages		3	$	565		2	$	467	$	1,032
Total		3	$	565		2	$	467	$	1,032

There were no delinquent troubled debt restructurings as of March 31, 2021 or December 31, 2020. Restructurings include deferrals of interest and/or principal payments and temporary or permanent reductions in interest rates due to the financial difficulties of the borrowers. At March 31, 2021, we had no commitments to lend any additional funds to these borrowers.

The Coronavirus Aid, Relief, and Economic Security (CARES) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act provides relief to financial institutions from categorizing eligible loan modifications as troubled debt restructurings over the remaining life of the modified loan. Eligible loan modifications under the CARES Act must be related to the COVID-19 pandemic and the borrower must not have been more than 30 days past due as of December 31, 2019. Loan modifications under the CARES Act must be executed during the period from March 1, 2020 to the earlier of 60 days after the end of the national emergency or January 1, 2022. Banking regulators issued similar guidance, which also clarified that a COVID-19 related loan modification should not be considered a troubled debt restructuring if the borrower was not more than 30 days past due on payments at the time the loan modification program was implemented and the modification is considered short-term (not to exceed six months). The Company uses the provisions of the CARES Act and the Interagency Statements to account for the eligible loans receiving modifications.

The Company has granted loan payment deferrals to borrowers who have been affected by the COVID-19 pandemic.  At March 31, 2021, the Company had outstanding loan payment deferrals on $119.8 million of loans, which represented 8.9% of total loans receivable.  Of these loans with payment deferrals, $115.2 million were one- to four-family residential mortgage loans and $4.5 million were non-residential mortgage loans, which represented 8.6% and 0.3% of total loans receivable, respectively. The loans on which the Company has granted loan payment deferrals are included in the ALLL calculation.  Loans performing under a loan payment deferral agreement are not contractually past due and are excluded from the past due statistics above.

The ratio of the current loan balance to the current tax-assessed value of the property securing the mortgage loans in the payment deferral program averaged 54.9% at March 31, 2021.  At March 31, 2021, one- to four-family residential mortgage loans represented 97.2% of the Company’s total loan portfolio balance with a ratio of the current loan balance to the current tax assessed value of the property securing these loans averaging 45.8%.  All of the Company’s residential mortgage loans are secured by real estate in Hawaii. 

As of March 31, 2021, of the $115.2 million total one- to four-family mortgage loans in the loan payment deferral program, $86.0 million, or 74.6%, had resumed making full principal and interest payments. The interest on these loans that accrued during the deferral period will be repaid over subsequent years. $24.9 million, or 21.6%, of the total mortgage loans in the loan payment deferral program were making interest-only payments. $2.1 million, or 1.8%, of the total mortgage loans in the loan payment deferral program continued to make escrow-only payments. $2.3 million, or 2.0%, of the total loans in the loan payment deferral program were still in their deferral period.

As of March 31, 2021, $4.1 million of the $4.5 million commercial mortgage, commercial and industrial and home equity lines of credit in the loan payment deferral program had resumed making full principal and interest payments. A $400,000 home equity line of credit was making interest-only payments.

16

Since the beginning of the year, we have not seen a significant increase in loan delinquencies, significant changes in deposits or significant drawdowns on any lines of credit. Loan delinquencies do not include loans requesting payment deferral because of the COVID-19 pandemic. We do not have any commercial loans to hotels, businesses in the transportation industry, restaurants or retail establishments.

The Company had no real estate owned as of March 31, 2021 or December 31, 2020. There was a one- to four-family residential mortgage loan for $99,000 in the process of foreclosure at March 31, 2021. There were two one- to four-family residential mortgage loans totaling $251,000 in the process of foreclosure at December 31, 2020.

Nearly all of our real estate loans are collateralized by real estate located in the State of Hawaii. Loan-to-value ratios on these real estate loans generally do not exceed 80% at the time of origination.

During the three months ended March 31, 2021 and 2020, the Company sold mortgage loans held for sale with principal balances of $12.2 million and $2.7 million, respectively, and recognized gains of $420,000 and $30,000, respectively. The Company had one loan held for sale for $253,000 at March 31, 2021 and five loans held for sale totaling $2.2 million at December 31, 2020.

During the three months ended March 31, 2020, the Company securitized fixed-rate first mortgage loans with a book value of $9.4 million and received mortgage-backed securities with a fair market value of $9.8 million. The Company retained the servicing of these loans and recorded mortgage servicing assets with a fair market value of $78,000. A net gain of $377,000 was recognized on the transaction. There were no securitization transactions in the three months ended March 31, 2021.

The Company serviced loans for others with principal balances of $52.3 million at March 31, 2021 and $56.7 million at December 31, 2020. Of these amounts, $32.6 million and $35.5 million of loan balances relate to securitizations for which the Company continues to hold the related mortgage-backed securities at March 31, 2021 and December 31, 2020, respectively. The amount of contractually specified servicing fees earned for the three months ended March 31, 2021 and 2020 was $36,000 and $44,000, respectively. The fees are reported in service and other fees in the Consolidated Statements of Income.

(7)      Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase are treated as financings and the obligations to repurchase the identical securities sold are reflected as a liability with the securities collateralizing the agreements classified as an asset. Securities sold under agreements to repurchase are summarized as follows:

	March 31, 2021				December 31, 2020
			Weighted				Weighted
	Repurchase		Average		Repurchase		Average
(Dollars in thousands)	Liability		Rate		Liability		Rate
Maturing:
Over 3 year to 4 years	$	10,000	1.81	%	$	5,000	1.88	%
Over 4 year to 5 years		—	—			5,000	1.73	%
Total	$	10,000	1.81	%	$	10,000	1.81	%

Below is a summary comparing the carrying value and fair value of securities pledged to secure repurchase agreements, the repurchase liability, and the amount at risk at March 31, 2021. The amount at risk is the greater of the carrying value or fair value over the repurchase liability and refers to the potential loss to the Company if the secured lender fails to return the security at the maturity date of the agreement. All the agreements to repurchase are with JP Morgan Securities and the securities pledged are mortgage-backed securities issued and guaranteed by U.S. government-sponsored enterprises. The repurchase liability cannot exceed 90% of the fair value of securities pledged. In the event

17

of a decline in the fair value of securities pledged to less than the required amount due to market conditions or principal repayments, the Company is obligated to pledge additional securities or other suitable collateral to cure the deficiency.

(9)    Employee Benefit Plans

The Company has a noncontributory defined benefit pension plan (Pension Plan) that covers most employees with at least one year of service. Effective December 31, 2008, under approved changes to the Pension Plan, there were no further accruals of benefits for any participants and benefits will not increase with any additional years of service. Net periodic benefit cost, subsequent to December 31, 2008, has not been significant and is not disclosed in the table below.

The Company also sponsors a Supplemental Employee Retirement Plan (SERP), a noncontributory supplemental retirement benefit plan, which covers certain current and former employees of the Company for amounts in addition to those provided under the Pension Plan.

The components of net periodic benefit cost were as follows:

	SERP

(10) Employee Stock Ownership Plan

Effective January 1, 2009, Territorial Savings Bank adopted an Employee Stock Ownership Plan (ESOP) for eligible employees. The ESOP borrowed $9.8 million from the Company and used those funds to acquire 978,650 shares, or 8%, of the total number of shares issued by the Company in its initial public offering. The shares were acquired at a price of $10.00 per share.

The loan is secured by the shares purchased with the loan proceeds and will be repaid by the ESOP over the 20-year term of the loan with funds from Territorial Savings Bank’s contributions to the ESOP and dividends payable on the shares. The interest rate on the ESOP loan is an adjustable rate equal to the prime rate, as published in The Wall Street Journal. The interest rate adjusts annually and will be the prime rate on the first business day of the calendar year.

Shares purchased by the ESOP are held by a trustee in an unallocated suspense account, and shares are released annually from the suspense account on a pro-rata basis as principal and interest payments are made by the ESOP to the Company. The trustee allocates the shares released among participants on the basis of each participant’s proportional share of compensation relative to all participants. As shares are committed to be released from the suspense account, Territorial Savings Bank reports compensation expense based on the average fair value of shares released with a corresponding credit to stockholders’ equity. The shares committed to be released are considered outstanding for earnings per share computations. Compensation expense recognized for the three months ended March 31, 2021 and 2020 amounted to $317,000 and $339,000, respectively.

Shares held by the ESOP trust were as follows:

	March 31,		December 31,
	2021		2020
Allocated shares		519,538		507,304
Unearned shares		379,230		391,464
Total ESOP shares		898,768		898,768
Fair value of unearned shares, in thousands	$	10,034	$	9,407

The ESOP restoration plan is a nonqualified plan that provides supplemental benefits to certain executives who are prevented from receiving the full benefits contemplated by the ESOP’s benefit formula. The supplemental cash payments consist of payments representing shares that cannot be allocated to the participants under the ESOP due to IRS limitations imposed on tax-qualified plans. We accrue for these benefits over the period during which employees provide services to earn these benefits. For the three months ended March 31, 2021 and 2020, we accrued $18,000 and $85,000, respectively, for the ESOP restoration plan.

(11)    Share-Based Compensation

The shareholders of Territorial Bancorp Inc. adopted the 2010 Equity Incentive Plan on August 19, 2010 and the 2019 Equity Incentive Plan on May 16, 2019. These plans provide for the award of stock options and restricted stock to key officers and directors. In accordance with the Compensation – Stock Compensation topic of the FASB ASC, the cost of the equity incentive plans is based on the fair value of the awards on the grant date. The fair value of restricted stock is based on the closing price of the Company’s stock on the grant date. The fair value of stock options is estimated using a Black-Scholes option pricing model using assumptions for dividend yield, stock price volatility, risk-free interest rate and option term. These assumptions are based on our judgments regarding future events, are subjective in nature, and cannot be determined with precision. The cost of the awards will be recognized on a straight-line basis over the three, five- or six-year vesting period during which participants are required to provide services in exchange for the awards.

The Company recognized compensation expense, measured as the fair value of the share-based award on the date of grant, on a straight-line basis over the vesting period. Share-based compensation is recorded in the statement of

19

income as a component of salaries and employee benefits with a corresponding increase in stockholders’ equity. The table below presents information on compensation expense and the related tax benefit for all share-based awards:

	Three Months Ended

Restricted Stock

Restricted stock awards are accounted for as fixed grants using the fair value of the Company’s stock at the time of grant. Unvested restricted stock may not be disposed of or transferred during the vesting period. Restricted stock carries the right to receive dividends, although dividends attributable to restricted stock are retained by the Company until the shares vest, at which time they are paid to the award recipient. Unvested restricted stock that is time-based contain nonforfeitable dividend rights.  Accrued dividends on restricted stock that do not vest based on performance or market conditions are forfeited. 

The table below presents the time-based restricted stock activity:

Unvested at March 31, 2020	26,899	$	24.87

As of March 31, 2021, the Company had $274,000 of unrecognized compensation costs related to restricted stock.

The Company issued performance-based restricted stock units (PRSUs) to certain members of executive management under the 2019 Equity Incentive Plan. These PRSUs will vest three years after they are granted after our Compensation Committee determines whether a performance condition that compares the Company’s return on average equity to the SNL Bank Index is achieved.  Depending on the Company’s performance, the actual number of these PRSUs that are issued at the end of the vesting period can vary between 0% to 150% of the target award.  For the PRSUs, an estimate is made of the number of shares expected to vest based on the probability that the performance criteria will be achieved to determine the amount of compensation expense to be recognized.  This estimate is re-evaluated quarterly and total compensation expense is adjusted for any change in the current period.

Forfeited	3,840		29.53
Unvested at March 31, 2020	40,585	$	25.83

The fair value of these PRSUs is based on the fair value of the Company’s stock on the date of grant. As of March 31, 2021, the Company had $262,000 of unrecognized compensation costs related to these PRSUs. Performance will be measured over a three-year performance period and will be cliff vested.

The Company also issued PRSUs to certain members of executive management under the 2019 Equity Incentive Plan.  These PRSUs will vest three years after they are granted after our Compensation Committee determines whether a market condition that compares the Company’s total stock return to the SNL Bank Index is achieved.  The number of shares that will be expensed will not be adjusted for performance.  The fair value of these PRSUs is based on a Monte Carlo valuation of the Company’s stock on the date of grant.

(12)    Earnings Per Share

Holders of unvested restricted stock accrue dividends at the same rate as common shareholders and they both share equally in undistributed earnings. Unvested restricted stock awards that are time-based contain nonforfeitable rights to dividends or dividend equivalents and are considered to be participating securities in the earnings per share computation using the two-class method. Under the two-class method, earnings are allocated to common shareholders and participating securities according to their respective rights to earnings. Unvested restricted stock awards that vest based on performance or market conditions are not considered to be participating securities in the earnings per share calculation because accrued dividends on shares that do not vest are forfeited.

(14)    Revenue Recognition

The Company’s contracts with customers are generally short-term in nature, with cycles of one year or less. These can range from an immediate term for services such as wire transfers, foreign currency exchanges and cashier’s check purchases, to several days for services such as processing annuity and mutual fund sales. Some contracts may be of an ongoing nature, such as providing deposit account services, including ATM access, check processing, account analysis and check ordering. However, provision of an assessable service and payment for such service is usually concurrent or closely timed. Contracts related to financial instruments, such as loans, investments and debt, are excluded from the scope of this reporting requirement.

After analyzing the Company’s revenue sources, including the amount of revenue received, the timing of services rendered and the timing of payment for these services, the Company has determined that the rendering of services and the payment for such services are generally closely matched. Any differences are not material to the Company’s consolidated financial statements. Accordingly, the Company generally records income when payment for services is received.

24

Revenue from contracts with customers is reported in service and other fees in other noninterest income in the consolidated statements of income. The table below reconciles the revenue from contracts with customers and other revenue reported in those line items:

(16)    Fair Value

In accordance with the Fair Value Measurements and Disclosures topic of the FASB ASC, the Company groups its financial assets and liabilities measured or disclosed at fair value into three levels based on the markets in which the financial assets and liabilities are traded and the reliability of the assumptions used to determine fair value as follows:

●Level 1 — Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities traded in active markets. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available.

●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 management’s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of discounted cash flow models and similar techniques that require the use of significant judgment or estimation.

In accordance with the Fair Value Measurements and Disclosures topic, the Company bases its fair values on the price that it would expect to receive if an asset were sold or the price that it would expect to pay to transfer a liability in an orderly transaction between market participants at the measurement date. Also as required, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when developing fair value measurements.

The Company uses fair value measurements to determine fair value disclosures. Investment securities held for sale and derivatives are recorded at fair value on a recurring basis. From time to time, the Company may be required to record other financial assets at fair value on a nonrecurring basis, such as loans held for sale, impaired loans and investments, and mortgage servicing assets. These nonrecurring fair value adjustments typically involve application of the lower of cost or fair value accounting or write-downs of individual assets.

Investment Securities Available for Sale. The estimated fair values of U.S. government-sponsored mortgage-backed securities are considered Level 2 inputs because the valuation for investment securities utilized pricing models that varied based on asset class and included trade, bid and other observable market information.

26

Interest Rate Contracts. The Company may enter into interest rate lock commitments with borrowers on loans intended to be sold. To manage interest rate risk on the lock commitments, the Company may also enter into forward loan sale commitments. The interest rate lock commitments and forward loan sale commitments are treated as derivatives and are recorded at their fair value determined by referring to prices quoted in the secondary market for similar contracts. The fair value inputs are considered Level 2 inputs. Interest rate contracts that are classified as assets are included with prepaid expenses and other assets on the Consolidated Balance Sheet while interest rate contracts that are classified as liabilities are included with accounts payable and accrued expenses.

The estimated fair values of the Company’s financial instruments are as follows:

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

Cautionary Statement Regarding Forward-Looking Information

This Quarterly Report contains forward-looking statements, which can be identified by the use of words such as “estimate,” “project,” “believe,” “intend,” “anticipate,” “plan,” “seek,” “expect,” “will,” “may,” “continue” and words of similar meaning. These forward-looking statements include, but are not limited to:

● statements of our goals, intentions and expectations;

● statements regarding our business plans, prospects, growth and operating strategies;

● statements regarding the asset quality of our loan and investment portfolios; and

● estimates of our risks and future costs and benefits.

These forward-looking statements are based on our current beliefs and expectations and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change. You should not place undue reliance on such statements. We are under no duty to and do not take any obligation to update any forward-looking statements after the date of this Quarterly Report.

The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements:

● the effect of any pandemic disease, including COVID-19, natural disaster, war, act of terrorism, accident or similar action or event;

● general economic conditions, either internationally, nationally or in our market areas, that are worse than expected;

● competition among depository and other financial institutions;

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

● adverse changes in the securities markets;

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

● changes in monetary or fiscal policies of the U.S. Government, including policies of the U.S. Treasury and the Federal Reserve Board;

● our ability to enter new markets successfully and capitalize on growth opportunities;

● our ability to successfully integrate acquired entities, if any;

● changes in consumer demand, spending, borrowing and savings habits;

● changes in accounting policies and practices, as may be adopted by the bank regulatory agencies, the Financial Accounting Standards Board, the Securities and Exchange Commission and the Public Company Accounting Oversight Board;

● changes in our organization, compensation and benefit plans;

29

● the timing and amount of revenues that we may recognize;

● the value and marketability of collateral underlying our loan portfolios;

● our ability to retain key employees;

● cyberattacks, computer viruses and other technological risks that may breach the security of our websites or other systems to obtain unauthorized access to confidential information, destroy data or disable our systems;

● technological change that may be more difficult or expensive than expected;

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

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

● the effects of any federal government shutdown;

● the quality and composition of our investment portfolio;

● changes in market and other conditions that would affect our ability to repurchase our common stock;

● changes in our financial condition or results of operations that reduce capital available to pay dividends; and

● changes in the financial condition or future prospects of issuers of securities that we own.

In addition, 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 coronavirus can be controlled and abated and when and how the economy may be reopened. As the result of the COVID-19 pandemic and the related adverse local and national economic consequences, we could be subject to any of the following risks, any of which could have a material, adverse effect on our business, financial condition, liquidity, and results of operations:

● demand for our products and services may decline, making it difficult 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 could cause loan losses to increase;

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

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

● as the result of the decline in the Federal Reserve Board’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;

● a material decrease in net income or a net loss over several quarters could result in a decrease in the rate of our quarterly cash dividend;

● our cyber security risks are increased as the result of an increase in the number of employees working remotely;

● we rely on third party vendors for certain services and the unavailability of a critical service due to the COVID-19 outbreak could have an adverse effect on us;

30

● Federal Deposit Insurance Corporation premiums may increase if the agency experiences additional resolution costs; and

● employees may have difficulty performing work if COVID-19 infections occur.

Because of these and a wide variety of other uncertainties, our actual future results may be materially different from the results indicated by these forward-looking statements.

Overview

We have historically operated as a traditional thrift institution. The significant majority of our assets consist of long-term, fixed-rate residential mortgage loans and mortgage-backed securities, which we have funded primarily with deposit inflows, cash balances at the Federal Reserve Bank, loan and security repayments, advances from the Federal Home Loan Bank, our capital, proceeds from securities sold under agreements to repurchase and proceeds from loan and security sales. As a result, we may be vulnerable to increases in interest rates, as our interest-bearing liabilities mature or reprice more quickly than our interest-earning assets.

We have continued our focus on originating one- to four-family residential real estate loans. Our emphasis on conservative loan underwriting has resulted in continued low levels of nonperforming assets. Our nonperforming assets, which can include nonaccrual loans and real estate owned, totaled $4.2 million, or 0.20% of total assets at March 31, 2021 compared to $4.4 million, or 0.21% of total assets at December 31, 2020. We reversed $913,000 in provisions for loan losses for the three months ended March 31, 2021 and recorded $217,000 of provisions for loan losses for the three months ended March 31, 2020. The reversal of loan loss provisions occurred primarily because of the decrease in the size of the loan portfolio and decreases in Hawaii’s unemployment rate and in the amount of loans in our loan payment deferral program. The loan payment deferral program was created to assist borrowers who were experiencing financial hardship due to the COVID-19 pandemic.

Other than our loans for the construction of one- to four-family residential homes, we do not offer “interest only” mortgage loans (where the borrower pays only interest for an initial period, after which the loan converts to a fully amortizing loan) on one- to four-family residential properties. We also do not offer loans that provide for negative amortization of principal, such as “Option ARM” loans, where the borrower can pay less than the interest owed on their loan, resulting in an increased principal balance during the life of the loan. We do not offer “subprime loans” (loans that generally target borrowers with weakened credit histories typically characterized by payment delinquencies, previous charge-offs, judgments, bankruptcies, or borrowers with questionable repayment capacity as evidenced by low credit scores or high debt-burden ratios) or Alt-A loans (traditionally defined as nonconforming loans having less than full documentation). We also do not own any private label mortgage-backed securities that are collateralized by Alt-A, low or no documentation or subprime mortgage loans.

We sold fixed-rate mortgage loans with principal balances of $12.2 million and $2.7 million during the three months ended March 31, 2021 and 2020, respectively. During the three months ended March 31, 2020, we also securitized fixed-rate first mortgage loans with a book value of $9.4 million and received mortgage-backed securities with a fair market value of $9.8 million. Federal Home Loan Bank advances remained constant at $141.0 million and $156.0 million for the three months ended March 31, 2021 and 2020, respectively. Securities sold under agreements to repurchase remained constant at $10.0 million for the three months ended March 31, 2021 and 2020.

Our investments in mortgage-backed securities have been issued by Freddie Mac or Fannie Mae, which are U.S. government-sponsored enterprises, or Ginnie Mae, which is a U.S. government agency. These entities guarantee the payment of principal and interest on our mortgage-backed securities. As of March 31, 2021 and December 31, 2020, we owned $298.3 million and $251.2 million, respectively, of mortgage-backed securities issued by Freddie Mac, Fannie Mae and Ginnie Mae.

Critical Accounting Policies

There are no material changes to the critical accounting policies disclosed in Territorial Bancorp Inc.’s Annual Report on Form 10-K for the year ended December 31, 2020.

Comparison of Financial Condition at March 31, 2021 and December 31, 2020

Assets. Our total assets increased by $28.8 million, or 1.4%, to $2.1 billion at March 31, 2021. The increase in assets was primarily due to a $47.3 million increase in cash and cash equivalents and a $47.1 million increase in total investment securities, which was partially offset by a $69.4 million decrease in total loans receivable.

Cash and Cash Equivalents. Cash and cash equivalents were $410.8 million at March 31, 2021, an increase of $47.3 million since December 31, 2020. The increase in cash and cash equivalents was primarily caused by a $69.4 million decrease in total loans receivable and a $27.3 million increase in deposits. These increases were partially offset by a $47.1 million increase in total investment securities.

Loans. Total loans, including $253,000 of loans held for sale, were $1.3 billion at March 31, 2021, or 62.6% of total assets. During the three months ended March 31, 2021, the loan portfolio, including loans held for sale, decreased by $69.4 million, or 4.9%. The decrease in the loan portfolio primarily occurred as principal repayments and loan sales exceeded the originations of new loans.

Securities. At March 31, 2021, our securities portfolio totaled $298.3 million, or 13.9% of total assets. During the three months ended March 31, 2021, the securities portfolio increased by $47.1 million, or 18.8%. The increase in the securities balance occurred as purchases exceeded the principal repayments and sales of securities.

At March 31, 2021, none of the underlying collateral consisted of subprime or Alt-A (traditionally defined as nonconforming loans having less than full documentation) loans.

Deposits. Deposits were $1.7 billion at March 31, 2021, an increase of $27.3 million, or 1.6%, since December 31, 2020. The growth in deposits was primarily due to increases of $42.3 million in savings accounts and $12.8 million in checking accounts. These increases were partially offset by a $27.6 million decrease in certificates of deposit during the three months ended March 31, 2021.

Borrowings. Our borrowings consist of advances from the Federal Home Loan Bank and funds borrowed under securities sold under agreements to repurchase. During the three months ending March 31, 2021, total borrowings remained constant at $151.0 million.

Stockholders’ Equity. Total stockholders’ equity was $251.7 million at March 31, 2021 and $248.7 million at December 31, 2020. The increase in stockholders’ equity occurred primarily due to net income of $5.0 million, which was partially offset by the declaration of $2.1 million of dividends.

Average Balances and Yields

The following tables set forth average balance sheets, average yields and rates, and certain other information for the periods indicated. No tax-equivalent yield adjustments were made, as we did not hold any tax-free investments. All average balances are daily average balances. Nonaccrual loans were included in the computation of average balances and are included with accrual loans in the tables. However, no interest income was attributed to nonaccrual loans. The yields set forth below include the effect of net deferred costs, discounts and premiums that are amortized or accreted to interest income.

Comparison of Operating Results for the Three Months Ended March 31, 2021 and 2020

General. Net income increased by $540,000, or 12.1%, from $4.5 million for the three months ended March 31, 2020 to $5.0 million for the three months ended March 31, 2021. The increase in net income was due to a $1.1 million decrease in loan loss provisions and a $938,000 increase in non-interest income. These increases to net income were partially offset by a $1.3 million decrease in net interest income and a $201,000 increase in income tax expense.

Net Interest Income. Net interest income decreased by $1.3 million, or 9.0%, to $13.2 million for the three months ended March 31, 2021 from $14.5 million for the three months ended March 31, 2020. Interest income decreased by $3.5 million, or 18.7%, due to a 69 basis point decrease in the average yield of interest-earning assets, which was partially offset by a $775,000 increase in the average balance of interest-earning assets. Interest expense decreased by $2.2 million, or 53.3%, due to a 49 basis point decrease in the cost of average interest-bearing liabilities, which was augmented by a $14.8 million decrease in the average balance of interest-bearing liabilities. The interest rate spread and net interest margin were 2.54% and 2.61% respectively, for the three months ended March 31, 2021, compared to 2.74% and 2.87%, respectively, for the three months ended March 31, 2020. The decreases in the interest rate spread and in the net interest margin are attributable to the 69 basis point decrease in the yield on average interest-bearing assets that was partially offset by the 49 basis point decrease in the cost of average interest-earning liabilities.

Interest Income. Interest income decreased by $3.5 million, or 18.7%, to $15.1 million for the three months ended March 31, 2021 from $18.6 million for the three months ended March 31, 2020. Interest income on loans decreased by $2.4 million, or 15.6%, to $13.0 million for the three months ended March 31, 2021 from $15.5 million for the three months ended March 31, 2020. The decrease in interest income on loans occurred because the average balance of loans decreased by $197.3 million, or 12.5%, and the average loan yield decreased by 14 basis points. The decrease in the average balance occurred as loan repayments and loan sales exceeded new loan originations. Interest income on securities decreased by $955,000, or 34.4%, to $1.8 million for the three months ended March 31, 2021 from $2.8 million for the three months ended March 31, 2020. The decrease in interest income on securities occurred primarily because the average balance of securities decreased by $91.2 million, or 24.9%, as security repayments and sales exceeded security purchases. The decrease in interest income on securities was augmented by a 38 basis point decrease in the average yield on securities, which occurred as higher yielding securities were paid off or sold and replaced with purchases of lower yielding securities in the current low interest rate environment.

Interest Expense. Interest expense decreased by $2.2 million, or 53.3%, to $1.9 million for the three months ended March 31, 2021 from $4.1 million for the three months ended March 31, 2020. Interest expense on interest-bearing deposits decreased by $1.8 million, or 57.8%, from $3.1 million for the three months ended March 31, 2020 to $1.3 million for the three months ended March 31, 2021. The decrease in interest expense on interest-bearing deposits was primarily due to a 46 basis point decrease in the average rate paid on interest-bearing deposits. The decrease in the average rate paid on interest bearing deposits was primarily due to lower interest rates offered on certificates of deposit and savings accounts. During the three months ended March 31, 2021, the average rate paid on certificates of deposit decreased by 53 basis points as average rates dropped from 1.79% to 1.26% as higher rate certificates of deposit matured. The average rate paid on savings accounts decreased by 29 basis points as average rates dropped from 0.43% to 0.14%. The decrease in the average rates on certificates of deposit and savings accounts occurred because of a decline in market interest rates. Interest expense on Federal Home Loan Bank (FHLB) advances decreased by $359,000, or 40.1%, from $895,000 for the three months ended March 31, 2020 to $536,000 for the three months ended March 31, 2021. The decrease in interest expense on FHLB advances was primarily due to a 77 basis point decrease in the average rate paid and a $15.0 million decrease in the average balance on FHLB advances. The decrease in the average rate paid on FHLB advances was due to restructuring of $82.0 million of FHLB advances in the year ended December 31, 2020. This transaction lowered the average cost of FHLB advances from 2.28% to 1.52% and extended the average maturity date by 1.9 years. The restructuring was accounted for as a continuation of the existing borrowings with any prepayment fees recognized as an adjustment to the future cost of the restructured advances. We primarily funded our operations with additional deposits, borrowings, proceeds from loan and security sales and principal repayments on loans and mortgage-backed securities.

Provision for Loan Losses. We recorded a reversal of provisions for loan losses of $913,000 for the three months ended March 31, 2021 and recorded provisions of $217,000 for the three months ended March 31, 2020. The

34

reversal of loan loss provisions occurred primarily because of the decrease in the size of the loan portfolio and in Hawaii’s unemployment rate as well as the increase in the amount of loans with higher loan-to-value ratios that have made six consecutive payments. The loan payment deferral program was created to assist borrowers who were experiencing financial hardship due to the COVID-19 pandemic. The provisions recorded resulted in ratios of the allowance for loan losses to total loans of 0.25% and 0.19% at March 31, 2021 and 2020, respectively. Nonaccrual loans totaled $4.2 million at March 31, 2021, or 0.31% of total loans at that date, compared to $708,000 of nonaccrual loans at March 31, 2020, or 0.05% of total loans at that date. Nonaccrual loans as of March 31, 2021 and 2020 consisted primarily of one- to four-family residential real estate loans. To the best of our knowledge, we have provided for all losses that are both probable and reasonable to estimate at March 31, 2021 and 2020. For additional information see Note (6), “Loans Receivable and Allowance for Loan Losses” in our Notes to Consolidated Financial Statements.

Noninterest Income. The following table summarizes changes in noninterest income between the three months ended March 31, 2021 and 2020.

	Three Months Ended
	March 31,				Change
	2021		2020		$ Change		% Change
				(Dollars in thousands)
Service and other fees	$	995	$	453	$	542	119.6	%
Income on bank-owned life insurance		188		202		(14)	(6.9)	%
Gain on sale of investment securities		526		178		348	195.5	%
Gain on sale of loans		420		407		13	3.2	%
Other		110		61		49	80.3	%
Total	$	2,239	$	1,301	$	938	72.1	%

Noninterest income increased by $938,000 for the three months ended March 31, 2021 compared to the three months ended March 31, 2020. Service and other fees increased due to an increase in fees earned for referring mortgage loans to other financial institutions and mortgage brokers. During the three months ended March 31, 2021, we sold $4.8 million of held-to-maturity mortgage-backed securities and $943,000 of available-for-sale mortgage-backed securities and recorded gains of $420,000 and $106,000, respectively. During the three months ended March 31, 2020, we sold $729,000 of held-to-maturity mortgage-backed securities and $1.7 million of available-for-sale mortgage-backed securities and recorded gains of $28,000 and $150,000, respectively. The sale of the held-to-maturity mortgage-backed securities, for which we had already collected a substantial portion of the outstanding purchased principal (at least 85%), were in accordance with the Investments – Debt and Equity Securities topic of the FASB ASC and do not taint management’s assertion of its intent to hold the remaining securities in the held-to-maturity portfolio to maturity.

Noninterest Expense. The following table summarizes changes in noninterest expense between the three months ended March 31, 2021 and 2020.

	Three Months Ended
	March 31,				Change
	2021		2020		$ Change		% Change
				(Dollars in thousands)
Salaries and employee benefits	$	5,523	$	5,684	$	(161)	(2.8)	%

Other general and administrative expenses		1,113		1,089		24	2.2	%
Total	$	9,554	$	9,538	$	16	0.2	%

Noninterest expense increased by $16,000 for the three months ended March 31, 2021 compared to the three months ended March 31, 2020. The increase in federal deposit insurance premiums occurred as we received credits in

35

the three months ended March 31, 2020 because the FDIC insurance fund was overcapitalized. The decrease in salaries and employee benefits was primarily due to an increase in the deferred salary expense for originating new loans.

Income Tax Expense. Income taxes were $1.8 million for the three months ended March 31, 2021, reflecting an effective tax rate of 26.3%, compared to $1.6 million for the three months ended March 31, 2020, reflecting an effective tax rate of 26.2%.

Liquidity and Capital Resources

Liquidity is the ability to meet current and future financial obligations. Our primary sources of funds consist of deposit inflows, cash balances at the Federal Reserve Bank, loan and security repayments, advances from the Federal Home Loan Bank, proceeds from securities sold under agreements to repurchase and proceeds from loan and security sales. While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows and mortgage and mortgage-backed security prepayments are greatly influenced by general interest rates, economic conditions and competition. We have established an Asset/Liability Management Committee, consisting of our President and Chief Executive Officer, our Vice Chairman and Co-Chief Operating Officer, our Senior Vice President and Chief Financial Officer and our Vice President and Controller, which is responsible for establishing and monitoring our liquidity targets and strategies in order to ensure that sufficient liquidity exists for meeting the borrowing needs and deposit withdrawals of our customers as well as unanticipated contingencies. We believe that we have enough sources of liquidity to satisfy our short- and long-term liquidity needs as of March 31, 2021.

We regularly monitor and adjust our investments in liquid assets based upon our assessment of:

(i) expected loan demand;

(ii) purchases and sales of investment securities;

(iii) expected deposit flows and borrowing maturities;

(iv) yields available on interest-earning deposits and securities; and

(v) the objectives of our asset/liability management program.

Excess liquid assets are invested generally in interest-earning deposits or securities and may also be used to pay off short-term borrowings.

Our most liquid asset is cash. The amount of this asset is dependent on our operating, financing, lending and investing activities during any given period. At March 31, 2021, our cash and cash equivalents totaled $410.8 million. On that date, we had $10.0 million in securities sold under agreements to repurchase outstanding and $141.0 million of Federal Home Loan Bank advances outstanding with the ability to borrow an additional $808.8 million under Federal Home Loan Bank advances. We have securities with a market value of $10.2 million pledged to the Federal Reserve Bank and have the ability to borrow up to $9.6 million using these securities as collateral.

Our cash flows are derived from operating activities, investing activities and financing activities as reported in our Consolidated Statements of Cash Flows included in our Consolidated Financial Statements.

At March 31, 2021, we had $10.2 million in loan commitments outstanding for fixed-rate loans and had $18.1 million in unused lines of credit to borrowers. Certificates of deposit due within one year at March 31, 2021 totaled $230.5 million, or 13.7% of total deposits. If these deposits do not remain with us, we may be required to seek other sources of funds, including loan and security sales, brokered deposits, securities sold under agreements to repurchase and Federal Home Loan Bank advances. Depending on market conditions, we may be required to pay higher rates on such deposits or other borrowings than we currently pay on the certificates of deposit due on or before March 31, 2022. We believe, however, based on past experience that a significant portion of such deposits will remain with us. We have the ability to attract and retain deposits by adjusting the interest rates offered.

36

Our primary investing activities are originating loans and purchasing mortgage-backed securities. During the three months ended March 31, 2021 and 2020 we originated $82.5 million and $41.3 million of loans, respectively. During the three months ended March 31, 2021 we purchased $84.1 million of securities. During the three months ended March 31, 2020 we did not purchase any investment securities.

Financing activities consist primarily of activity in deposit accounts, Federal Home Loan Bank advances, securities sold under agreements to repurchase, stock repurchases and dividend payments. We experienced a net increase in deposits of $27.3 million and $25.1 million for the three months ended March 31, 2021 and 2020, respectively. Deposit flows are affected by the overall level of interest rates, the interest rates and products offered by us and our local competitors, and by other factors.

Liquidity management is both a daily and long-term function of business management. If we require funds beyond our ability to generate them internally, borrowing agreements exist with the Federal Home Loan Bank, which provide an additional source of funds. FHLB advances were $141.0 million at March 31, 2021 and December 31, 2020. We had the ability to borrow up to an additional $808.8 million and $807.2 million from the FHLB as of March 31, 2021 and December 31, 2020, respectively. We also utilize securities sold under agreements to repurchase as another borrowing source. Securities sold under agreements to repurchase were $10.0 million at March 31, 2021 and December 31, 2020.

Territorial Bancorp Inc. is a separate legal entity from Territorial Savings Bank and must provide for its own liquidity to pay dividends, repurchase shares of its common stock and for other corporate purposes. Territorial Bancorp Inc.’s primary source of liquidity is dividend payments from Territorial Savings Bank. The ability of Territorial Savings Bank to pay dividends to Territorial Bancorp Inc. is subject to regulatory requirements. At March 31, 2021, Territorial Bancorp Inc. (on an unconsolidated, stand-alone basis) had liquid assets of $15.1 million.

Territorial Savings Bank is subject to various regulatory capital requirements, including a risk-based capital measure. The risk-based capital guidelines include both a definition of capital and a framework for calculating risk-weighted assets by assigning balance sheet assets and off-balance sheet items to broad risk categories. Territorial Bancorp Inc. is not subject to regulatory capital requirements because its total assets are less than $3.0 billion. At March 31, 2021, Territorial Savings Bank exceeded all of its regulatory capital requirements and is considered to be “well capitalized” under regulatory guidelines.

37

The tables below present the fully-phased in capital required to be considered “well-capitalized” and meet the regulatory capital conservation buffer requirement as a percentage of total and risk-weighted assets and the percentage and the total amount of capital maintained for Territorial Savings Bank and the Company at March 31, 2021 and December 31, 2020:

(1) The required Common Equity Tier 1 Risk-Based Capital, Tier 1 Risk-Based Capital and Total Risk-Based Capital ratios are based on the fully-phased in capital ratios in the Basel III capital regulations plus the 2.50% capital conservation buffer that became effective on January 1, 2019.

Prompt Corrective Action provisions define specific capital categories based on an institution’s capital ratios. However, the regulators may impose higher minimum capital standards on individual institutions or may downgrade an institution from one capital category to a lower category because of safety and soundness concerns. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our consolidated financial statements.

Prompt Corrective Action provisions impose certain restrictions on institutions that are undercapitalized. The restrictions imposed become increasingly more severe as an institution’s capital category declines from “undercapitalized” to “critically undercapitalized.”

At March 31, 2021 and December 31, 2020, the Bank’s capital ratios exceeded the minimum capital thresholds for a “well-capitalized” institution. There are no conditions or events that have changed the institution’s category under the capital guidelines.

Depending on the amount of dividends to be paid, the Bank is required to either notify or make application to the Federal Reserve Bank before dividends are paid to the Company.

38

Legislation enacted in 2018 requires the federal banking agencies, including the Federal Reserve Board, to establish a “community bank leverage ratio” between 8% to 10% of average total consolidated assets for qualifying institutions with assets of less than $10 billion. Institutions with capital meeting the specified requirements and electing to follow the alternative framework would be deemed to comply with the applicable regulatory capital requirements, including the risk based requirements. The federal regulators have adopted 9% as the applicable ratio, effective March 31, 2020, and reduced the ratio to 8% as a result of the CARES Act. We have not adopted the alternative framework, with the applicable regulatory requirements.

Off-Balance Sheet Arrangements and Aggregate Contractual Obligations

Commitments. As a financial services provider, we routinely are a party to various financial instruments with off-balance sheet risks, such as commitments to extend credit and unused lines of credit. While these contractual obligations represent our potential future cash requirements, a significant portion of commitments to extend credit may expire without being drawn upon. Such commitments are subject to the same credit policies and approval process accorded to loans we make. In addition, we enter into commitments to sell mortgage loans.

Contractual Obligations. In the ordinary course of our operations, we enter into certain contractual obligations. Such obligations include operating leases for premises and equipment, agreements with respect to borrowed funds and deposit liabilities and agreements with respect to investments. Except for a decrease of $27.6 million in certificates of deposit and a decrease of $11.1 million in loan commitments between December 31, 2020 and March 31, 2021, there have not been any material changes in our contractual obligations and funding needs since December 31, 2020.

ITEM 3.      QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

General. Our most significant form of market risk is interest rate risk because, as a financial institution, the majority of our assets and liabilities are sensitive to changes in interest rates. Therefore, a principal part of our operations is to manage interest rate risk and limit the exposure of our net interest income to changes in market interest rates. Our Board of Directors has established an Asset/Liability Management Committee, which is responsible for evaluating the interest rate risk inherent in our assets and liabilities, for determining the level of risk that is appropriate, given our business strategy, operating environment, capital, liquidity and performance objectives, and for managing this risk consistent with the guidelines approved by the Board of Directors.

Because we have historically operated as a traditional thrift institution, the significant majority of our assets consist of long-term, fixed-rate residential mortgage loans and mortgage-backed securities, which we have funded primarily with deposit inflows, cash balances at the Federal Reserve Bank, loan and security repayments, advances from the Federal Home Loan Bank, our capital, proceeds from securities sold under agreements to repurchase and proceeds from loan and security sales. In addition, there is little demand for adjustable-rate mortgage loans in the Hawaii market area. This has resulted in our being particularly vulnerable to increases in interest rates, as our interest-bearing liabilities mature or reprice more quickly than our interest-earning assets. We sold $12.2 million and $2.7 million of fixed-rate mortgage loans during the three months ended March 31, 2021 and 2020, respectively, to reduce our interest rate risk.

Our policies do not permit hedging activities, such as engaging in futures, options or swap transactions, or investing in high-risk mortgage derivatives, such as collateralized mortgage obligation residual interests, real estate mortgage investment conduit residual interests or stripped mortgage-backed securities.

Economic Value of Equity. We use an interest rate sensitivity analysis that computes changes in the economic value of equity (EVE) of our cash flows from assets, liabilities and off-balance sheet items in the event of a range of assumed changes in market interest rates. EVE represents the market value of portfolio equity and is equal to the present value of assets minus the present value of liabilities, with adjustments made for off-balance sheet items. This analysis assesses the risk of loss in market-risk-sensitive instruments in the event of an instantaneous and sustained 100 to 400 basis point increase or a 100 basis point decrease in market interest rates with no effect given to any steps that we might take to counter the effect of that interest rate movement. A basis point equals one-hundredth of one percent, and 100 basis points equals one percent. An increase in interest rates from 3% to 4% would mean, for example, a 100 basis point increase in the “Change in Interest Rates” column below. Given the current relatively low level of market interest rates, an EVE calculation for an interest rate decrease of greater than 100 basis points has not been prepared.

39

The following table presents our internal calculations of the estimated changes in our EVE as of December 31, 2020 (the latest date for which we have available information) that would result from the designated instantaneous changes in the interest rate yield curve.

-100	$	196,287	$	(81,712)	(29.39)	%	9.05	%	(3.84)	%

(1) Assumes an instantaneous uniform change in interest rates at all maturities.

(2) EVE is the difference between the present value of an institution’s assets and liabilities.

(3) Present value of assets represents the discounted present value of incoming cash flows on interest-earning assets.

(4) EVE Ratio represents EVE divided by the present value of assets.

Interest rates on Freddie Mac mortgage-backed securities have increased by 56 basis points between December 31, 2020 and March 31, 2021. The increase in mortgage interest rates is not expected to have a significant effect on estimated EVE.

Certain shortcomings are inherent in the methodologies used in determining interest rate risk through changes in EVE. Modeling changes in EVE requires making certain assumptions that may or may not reflect the manner in which actual yields and costs respond to changes in market interest rates. In this regard, the EVE table presented assumes that the composition of our interest-sensitive assets and liabilities existing at the beginning of a period remains constant over the period being measured and assumes that a particular change in interest rates is reflected uniformly across the yield curve regardless of the duration or repricing of specific assets and liabilities. Accordingly, although the EVE table provides an indication of our interest rate risk exposure at a particular point in time, such measurements are not intended to and do not provide a precise forecast of the effect of changes in market interest rates on our EVE and net interest income and will differ from actual results.

ITEM 4.      CONTROLS AND PROCEDURES

An evaluation was performed under the supervision and with the participation of the Company’s management, including the Chairman of the Board, President and Chief Executive Officer and the Senior Vice President and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities and Exchange Act of 1934, as amended) as of March 31, 2021.

In June 2016, the Financial Accounting Standards Board (FASB) amended various sections of the FASB Accounting Standards Codification (ASC) related to the accounting for credit losses on financial instruments. The amendment changes the threshold for recognizing losses from a “probable” to an “expected” model. The new model is referred to as the current expected credit loss model and applies to loans, leases, held-to-maturity investments, loan commitments and financial guarantees. The amendment requires the measurement of all expected credit losses for financial assets as of the reporting date (including historical experience, current conditions and reasonable and supportable forecasts) and enhanced disclosures that will help financial statement users understand the estimates and judgments used in estimating credit losses and evaluating the credit quality of an organization’s portfolio. The amendment is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In November 2019, the FASB issued an update that delays the effective date of the amendment for smaller reporting companies, as defined by the Securities and Exchange Commission, to fiscal years beginning after December 15, 2022. The Company is a smaller reporting company. The Company will apply the amendment’s provisions as a cumulative-effect adjustment to retained earnings at the beginning of the first period the amendment is effective. The Company has formed a team that is working on an implementation plan to adopt the amendment. The implementation plan will include developing policies, procedures and internal controls over the model. The Company is also working with a software vendor to measure expected losses required by the amendment. The Company is currently evaluating the effects that the adoption of this amendment will have on its consolidated financial statements and expects that the portfolio composition and economic conditions at the time of adoption will influence the accounting adjustment made at the time the amendment is adopted.

The Coronavirus Aid, Relief, and Economic Security (CARES) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act provides relief to financial institutions from categorizing eligible loan modifications as troubled debt restructurings over the remaining life of the modified loan. Eligible loan modifications under the CARES Act must be related to the COVID-19 pandemic and the borrower must not have been more than 30 days past due as of December 31, 2019. Loan modifications under the CARES Act must be executed during the period from March 1, 2020 to the earlier of December 31, 2020 or 60 days after the end of the national emergency. On December 21, 2020, legislation extended the troubled debt restructuring relief provisions of the CARES Act to January

1, 2022. Banking regulators issued similar guidance, which also clarified that a COVID-19 loan modification should not be considered a troubled debt restructuring if the borrower was not more than 30 days past due on payments at the time the loan modification program was implemented and the modification is considered short-term (not to exceed six months).

During the three months ended March 31, 2021 and 2020, the Company sold $4.8 million and $729,000, respectively, of held-to-maturity mortgage-backed securities and recorded gains of $420,000 and $28,000, respectively. The sale of the mortgage-backed securities, for which the Company had already collected a substantial portion of the outstanding purchased principal (at least 85%), were in accordance with the Investments – Debt and Equity Securities topic of the FASB ASC and do not taint management’s assertion of its intent to hold the remaining securities in the held-to-maturity portfolio to maturity.

During the three months ended March 31, 2021 and 2020, the Company sold $943,000 and $1.7 million, respectively, of available-for-sale mortgage-backed securities and recorded gains of $106,000 and $150,000, respectively.

Investment securities with amortized costs of $170.5 million and $192.7 million at March 31, 2021 and December 31, 2020, respectively, were pledged to secure deposits made by state and local governments, securities sold under agreements to repurchase and transaction clearing accounts.

Provided below is a summary of investment securities which were in an unrealized loss position at March 31, 2021 and December 31, 2020. The Company does not intend to sell held-to-maturity and available-for-sale securities

until such time as the value recovers or the securities mature and it is not more likely than not that the Company will be required to sell the securities prior to recovery of value or the securities mature.

Mortgage-Backed Securities. The unrealized losses on the Company’s investment in mortgage-backed securities were caused by increases in market interest rates subsequent to purchase. All of the mortgage-backed securities are guaranteed by Freddie Mac or Fannie Mae, which are U.S. government-sponsored enterprises, or Ginnie Mae, which is a U.S. government agency. Since the decline in market value is attributable to changes in interest rates and not credit quality, and the Company does not intend to sell these investments until maturity and it is not more likely than not that the Company will be required to sell such investments prior to recovery of its cost basis, the Company does not consider these investments to be other-than-temporarily impaired as of March 31, 2021 or December 31, 2020.

During the three months ended March 31, 2020, the Company securitized fixed-rate first mortgage loans with a book value of $9.4 million into Freddie Mac mortgage-backed securities to increase liquidity. The securitization transaction increased investment securities and lowered loans receivable. The securitization transaction was accounted for by recording the mortgage-backed securities at a fair value of $9.8 million. A net gain of $377,000 was recognized on the securitization transaction and recorded in gain on sale of loans in the Consolidated Statements of Income. There were no securitization transactions during the three months ended March 31, 2021.

Management considers the allowance for loan losses at March 31, 2021 to be at an appropriate level to provide for probable losses that can be reasonably estimated based on general and specific conditions at that date. While the Company uses the best information it has available to make evaluations, future adjustments to the allowance may be necessary if conditions differ substantially from the information used in making the evaluations. To the extent actual outcomes differ from the estimates, additional provisions for credit losses may be required that would reduce future earnings. In addition, as an integral part of their examination process, the bank regulators periodically review the allowance for loan losses and may require the Company to increase the allowance based on their analysis of information available at the time of their examination.

The table below presents the balance in the allowance for loan losses and the recorded investment in loans, net of unearned fees and discounts, by portfolio segment and based on impairment method:

There were no loans individually evaluated for impairment with a related allowance for loan loss as of March 31, 2021 or December 31, 2020. Loans individually evaluated for impairment do not have an allocated allowance for loan loss because they are written down to fair value at the time of impairment.

The Company had 11 nonaccrual loans with a book value of $4.2 million as of March 31, 2021 and 12 nonaccrual loans with a book value of $4.4 million as of December 31, 2020. The Company collected interest on nonaccrual loans of $42,000 and $17,000 during the three months ended March 31, 2021 and 2020, respectively, but due to accounting and regulatory requirements, the Company recorded the interest as a reduction of principal. The Company would have recognized additional interest income of $94,000 and $15,000 during the three months ended March 31, 2021 and 2020, respectively, had the loans been accruing interest. The Company did not have any loans 90 days or more past due and still accruing interest as of March 31, 2021 and December 31, 2020.

The table below presents the aging of loans and accrual status by class of loans, net of unearned fees and discounts.

The Company primarily uses the aging of loans and accrual status to monitor the credit quality of its loan portfolio. When a mortgage loan becomes seriously delinquent (90 days or more contractually past due), it displays weaknesses that may result in a loss. As a loan becomes more delinquent, the likelihood of the borrower repaying the loan decreases and the loan becomes more collateral-dependent. A mortgage loan becomes collateral-dependent when the proceeds for repayment can be expected to come only from the sale or operation of the collateral and not from borrower repayments. Generally, appraisals are obtained after a loan becomes collateral-dependent or is four months delinquent. The carrying value of collateral-dependent loans is adjusted to the fair value of the collateral less selling costs. Any commercial real estate, commercial, construction or equity loan that has a loan balance in excess of a specified amount is also periodically reviewed to determine whether the loan exhibits any weaknesses and is performing in accordance with its contractual terms.

There were no loans modified in a troubled debt restructuring during the three months ended March 31, 2021 or 2020. There were no new troubled debt restructurings within the three months ended March 31, 2021 or 2020 that subsequently defaulted. Loan modifications under the CARES Act and the Interagency Statements issued by bank regulators in 2020 are discussed below.

The table below summarizes outstanding troubled debt restructurings by class of loans:

	Number of		Accrual		Number of		Nonaccrual
(Dollars in thousands)	Loans		Status		Loans		Status		Total

Total		3	$	565		2	$	467	$	1,032

There were no delinquent troubled debt restructurings as of March 31, 2021 or December 31, 2020. Restructurings include deferrals of interest and/or principal payments and temporary or permanent reductions in interest rates due to the financial difficulties of the borrowers. At March 31, 2021, we had no commitments to lend any additional funds to these borrowers.

The Coronavirus Aid, Relief, and Economic Security (CARES) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act provides relief to financial institutions from categorizing eligible loan modifications as troubled debt restructurings over the remaining life of the modified loan. Eligible loan modifications under the CARES Act must be related to the COVID-19 pandemic and the borrower must not have been more than 30 days past due as of December 31, 2019. Loan modifications under the CARES Act must be executed during the period from March 1, 2020 to the earlier of 60 days after the end of the national emergency or January 1, 2022. Banking regulators issued similar guidance, which also clarified that a COVID-19 related loan modification should not be considered a troubled debt restructuring if the borrower was not more than 30 days past due on payments at the time the loan modification program was implemented and the modification is considered short-term (not to exceed six months). The Company uses the provisions of the CARES Act and the Interagency Statements to account for the eligible loans receiving modifications.

The Company has granted loan payment deferrals to borrowers who have been affected by the COVID-19 pandemic.  At March 31, 2021, the Company had outstanding loan payment deferrals on $119.8 million of loans, which represented 8.9% of total loans receivable.  Of these loans with payment deferrals, $115.2 million were one- to four-family residential mortgage loans and $4.5 million were non-residential mortgage loans, which represented 8.6% and 0.3% of total loans receivable, respectively. The loans on which the Company has granted loan payment deferrals are included in the ALLL calculation.  Loans performing under a loan payment deferral agreement are not contractually past due and are excluded from the past due statistics above.

The ratio of the current loan balance to the current tax-assessed value of the property securing the mortgage loans in the payment deferral program averaged 54.9% at March 31, 2021.  At March 31, 2021, one- to four-family residential mortgage loans represented 97.2% of the Company’s total loan portfolio balance with a ratio of the current loan balance to the current tax assessed value of the property securing these loans averaging 45.8%.  All of the Company’s residential mortgage loans are secured by real estate in Hawaii. 

As of March 31, 2021, of the $115.2 million total one- to four-family mortgage loans in the loan payment deferral program, $86.0 million, or 74.6%, had resumed making full principal and interest payments. The interest on these loans that accrued during the deferral period will be repaid over subsequent years. $24.9 million, or 21.6%, of the total mortgage loans in the loan payment deferral program were making interest-only payments. $2.1 million, or 1.8%, of the total mortgage loans in the loan payment deferral program continued to make escrow-only payments. $2.3 million, or 2.0%, of the total loans in the loan payment deferral program were still in their deferral period.

As of March 31, 2021, $4.1 million of the $4.5 million commercial mortgage, commercial and industrial and home equity lines of credit in the loan payment deferral program had resumed making full principal and interest payments. A $400,000 home equity line of credit was making interest-only payments.

Since the beginning of the year, we have not seen a significant increase in loan delinquencies, significant changes in deposits or significant drawdowns on any lines of credit. Loan delinquencies do not include loans requesting payment deferral because of the COVID-19 pandemic. We do not have any commercial loans to hotels, businesses in the transportation industry, restaurants or retail establishments.

The Company had no real estate owned as of March 31, 2021 or December 31, 2020. There was a one- to four-family residential mortgage loan for $99,000 in the process of foreclosure at March 31, 2021. There were two one- to four-family residential mortgage loans totaling $251,000 in the process of foreclosure at December 31, 2020.

Nearly all of our real estate loans are collateralized by real estate located in the State of Hawaii. Loan-to-value ratios on these real estate loans generally do not exceed 80% at the time of origination.

During the three months ended March 31, 2021 and 2020, the Company sold mortgage loans held for sale with principal balances of $12.2 million and $2.7 million, respectively, and recognized gains of $420,000 and $30,000, respectively. The Company had one loan held for sale for $253,000 at March 31, 2021 and five loans held for sale totaling $2.2 million at December 31, 2020.

During the three months ended March 31, 2020, the Company securitized fixed-rate first mortgage loans with a book value of $9.4 million and received mortgage-backed securities with a fair market value of $9.8 million. The Company retained the servicing of these loans and recorded mortgage servicing assets with a fair market value of $78,000. A net gain of $377,000 was recognized on the transaction. There were no securitization transactions in the three months ended March 31, 2021.

The Company serviced loans for others with principal balances of $52.3 million at March 31, 2021 and $56.7 million at December 31, 2020. Of these amounts, $32.6 million and $35.5 million of loan balances relate to securitizations for which the Company continues to hold the related mortgage-backed securities at March 31, 2021 and December 31, 2020, respectively. The amount of contractually specified servicing fees earned for the three months ended March 31, 2021 and 2020 was $36,000 and $44,000, respectively. The fees are reported in service and other fees in the Consolidated Statements of Income.

Below is a summary comparing the carrying value and fair value of securities pledged to secure repurchase agreements, the repurchase liability, and the amount at risk at March 31, 2021. The amount at risk is the greater of the carrying value or fair value over the repurchase liability and refers to the potential loss to the Company if the secured lender fails to return the security at the maturity date of the agreement. All the agreements to repurchase are with JP Morgan Securities and the securities pledged are mortgage-backed securities issued and guaranteed by U.S. government-sponsored enterprises. The repurchase liability cannot exceed 90% of the fair value of securities pledged. In the event

of a decline in the fair value of securities pledged to less than the required amount due to market conditions or principal repayments, the Company is obligated to pledge additional securities or other suitable collateral to cure the deficiency.

Employee Stock Ownership Plan

(10) Employee Stock Ownership Plan

Effective January 1, 2009, Territorial Savings Bank adopted an Employee Stock Ownership Plan (ESOP) for eligible employees. The ESOP borrowed $9.8 million from the Company and used those funds to acquire 978,650 shares, or 8%, of the total number of shares issued by the Company in its initial public offering. The shares were acquired at a price of $10.00 per share.

The loan is secured by the shares purchased with the loan proceeds and will be repaid by the ESOP over the 20-year term of the loan with funds from Territorial Savings Bank’s contributions to the ESOP and dividends payable on the shares. The interest rate on the ESOP loan is an adjustable rate equal to the prime rate, as published in The Wall Street Journal. The interest rate adjusts annually and will be the prime rate on the first business day of the calendar year.

Shares purchased by the ESOP are held by a trustee in an unallocated suspense account, and shares are released annually from the suspense account on a pro-rata basis as principal and interest payments are made by the ESOP to the Company. The trustee allocates the shares released among participants on the basis of each participant’s proportional share of compensation relative to all participants. As shares are committed to be released from the suspense account, Territorial Savings Bank reports compensation expense based on the average fair value of shares released with a corresponding credit to stockholders’ equity. The shares committed to be released are considered outstanding for earnings per share computations. Compensation expense recognized for the three months ended March 31, 2021 and 2020 amounted to $317,000 and $339,000, respectively.

Shares held by the ESOP trust were as follows:

	March 31,		December 31,
	2021		2020
Allocated shares		519,538		507,304
Unearned shares		379,230		391,464
Total ESOP shares		898,768		898,768
Fair value of unearned shares, in thousands	$	10,034	$	9,407

The ESOP restoration plan is a nonqualified plan that provides supplemental benefits to certain executives who are prevented from receiving the full benefits contemplated by the ESOP’s benefit formula. The supplemental cash payments consist of payments representing shares that cannot be allocated to the participants under the ESOP due to IRS limitations imposed on tax-qualified plans. We accrue for these benefits over the period during which employees provide services to earn these benefits. For the three months ended March 31, 2021 and 2020, we accrued $18,000 and $85,000, respectively, for the ESOP restoration plan.

(11)    Share-Based Compensation

The shareholders of Territorial Bancorp Inc. adopted the 2010 Equity Incentive Plan on August 19, 2010 and the 2019 Equity Incentive Plan on May 16, 2019. These plans provide for the award of stock options and restricted stock to key officers and directors. In accordance with the Compensation – Stock Compensation topic of the FASB ASC, the cost of the equity incentive plans is based on the fair value of the awards on the grant date. The fair value of restricted stock is based on the closing price of the Company’s stock on the grant date. The fair value of stock options is estimated using a Black-Scholes option pricing model using assumptions for dividend yield, stock price volatility, risk-free interest rate and option term. These assumptions are based on our judgments regarding future events, are subjective in nature, and cannot be determined with precision. The cost of the awards will be recognized on a straight-line basis over the three, five- or six-year vesting period during which participants are required to provide services in exchange for the awards.

The Company recognized compensation expense, measured as the fair value of the share-based award on the date of grant, on a straight-line basis over the vesting period. Share-based compensation is recorded in the statement of

income as a component of salaries and employee benefits with a corresponding increase in stockholders’ equity. The table below presents information on compensation expense and the related tax benefit for all share-based awards:

Restricted Stock

Restricted stock awards are accounted for as fixed grants using the fair value of the Company’s stock at the time of grant. Unvested restricted stock may not be disposed of or transferred during the vesting period. Restricted stock carries the right to receive dividends, although dividends attributable to restricted stock are retained by the Company until the shares vest, at which time they are paid to the award recipient. Unvested restricted stock that is time-based contain nonforfeitable dividend rights.  Accrued dividends on restricted stock that do not vest based on performance or market conditions are forfeited. 

The table below presents the time-based restricted stock activity:

As of March 31, 2021, the Company had $274,000 of unrecognized compensation costs related to restricted stock.

The Company issued performance-based restricted stock units (PRSUs) to certain members of executive management under the 2019 Equity Incentive Plan. These PRSUs will vest three years after they are granted after our Compensation Committee determines whether a performance condition that compares the Company’s return on average equity to the SNL Bank Index is achieved.  Depending on the Company’s performance, the actual number of these PRSUs that are issued at the end of the vesting period can vary between 0% to 150% of the target award.  For the PRSUs, an estimate is made of the number of shares expected to vest based on the probability that the performance criteria will be achieved to determine the amount of compensation expense to be recognized.  This estimate is re-evaluated quarterly and total compensation expense is adjusted for any change in the current period.

The table below presents the PRSUs that will vest on a performance condition:

	Performance-

The fair value of these PRSUs is based on the fair value of the Company’s stock on the date of grant. As of March 31, 2021, the Company had $262,000 of unrecognized compensation costs related to these PRSUs. Performance will be measured over a three-year performance period and will be cliff vested.

The Company also issued PRSUs to certain members of executive management under the 2019 Equity Incentive Plan.  These PRSUs will vest three years after they are granted after our Compensation Committee determines whether a market condition that compares the Company’s total stock return to the SNL Bank Index is achieved.  The number of shares that will be expensed will not be adjusted for performance.  The fair value of these PRSUs is based on a Monte Carlo valuation of the Company’s stock on the date of grant.

Holders of unvested restricted stock accrue dividends at the same rate as common shareholders and they both share equally in undistributed earnings. Unvested restricted stock awards that are time-based contain nonforfeitable rights to dividends or dividend equivalents and are considered to be participating securities in the earnings per share computation using the two-class method. Under the two-class method, earnings are allocated to common shareholders and participating securities according to their respective rights to earnings. Unvested restricted stock awards that vest based on performance or market conditions are not considered to be participating securities in the earnings per share calculation because accrued dividends on shares that do not vest are forfeited.

The Company’s contracts with customers are generally short-term in nature, with cycles of one year or less. These can range from an immediate term for services such as wire transfers, foreign currency exchanges and cashier’s check purchases, to several days for services such as processing annuity and mutual fund sales. Some contracts may be of an ongoing nature, such as providing deposit account services, including ATM access, check processing, account analysis and check ordering. However, provision of an assessable service and payment for such service is usually concurrent or closely timed. Contracts related to financial instruments, such as loans, investments and debt, are excluded from the scope of this reporting requirement.

After analyzing the Company’s revenue sources, including the amount of revenue received, the timing of services rendered and the timing of payment for these services, the Company has determined that the rendering of services and the payment for such services are generally closely matched. Any differences are not material to the Company’s consolidated financial statements. Accordingly, the Company generally records income when payment for services is received.

Revenue from contracts with customers is reported in service and other fees in other noninterest income in the consolidated statements of income. The table below reconciles the revenue from contracts with customers and other revenue reported in those line items:

(16)    Fair Value

In accordance with the Fair Value Measurements and Disclosures topic of the FASB ASC, the Company groups its financial assets and liabilities measured or disclosed at fair value into three levels based on the markets in which the financial assets and liabilities are traded and the reliability of the assumptions used to determine fair value as follows:

●Level 1 — Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities traded in active markets. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available.

●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 management’s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of discounted cash flow models and similar techniques that require the use of significant judgment or estimation.

In accordance with the Fair Value Measurements and Disclosures topic, the Company bases its fair values on the price that it would expect to receive if an asset were sold or the price that it would expect to pay to transfer a liability in an orderly transaction between market participants at the measurement date. Also as required, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when developing fair value measurements.

The Company uses fair value measurements to determine fair value disclosures. Investment securities held for sale and derivatives are recorded at fair value on a recurring basis. From time to time, the Company may be required to record other financial assets at fair value on a nonrecurring basis, such as loans held for sale, impaired loans and investments, and mortgage servicing assets. These nonrecurring fair value adjustments typically involve application of the lower of cost or fair value accounting or write-downs of individual assets.

Investment Securities Available for Sale. The estimated fair values of U.S. government-sponsored mortgage-backed securities are considered Level 2 inputs because the valuation for investment securities utilized pricing models that varied based on asset class and included trade, bid and other observable market information.

Interest Rate Contracts. The Company may enter into interest rate lock commitments with borrowers on loans intended to be sold. To manage interest rate risk on the lock commitments, the Company may also enter into forward loan sale commitments. The interest rate lock commitments and forward loan sale commitments are treated as derivatives and are recorded at their fair value determined by referring to prices quoted in the secondary market for similar contracts. The fair value inputs are considered Level 2 inputs. Interest rate contracts that are classified as assets are included with prepaid expenses and other assets on the Consolidated Balance Sheet while interest rate contracts that are classified as liabilities are included with accounts payable and accrued expenses.

The estimated fair values of the Company’s financial instruments are as follows:
