In the first quarter of 2020, the Company reassessed the alignment of its reportable segments and combined its three reportable segments (Banking Operations, Treasury and All Others segments) into a single operating segment. We believe this change better reflects how the Company's Executive Committee, or its chief operating decision maker ("CODM"), manages, allocates resources and assesses performance of the activities of the Company. The Company also believes that this change is better aligned with how the Company's CODM manages its business. Segment results for 2019 have been reclassified to reflect the realignment of the Company’s reportable segments and be comparable to the segment results for 2020. This change in reportable segments did not have an impact on the Company's previously reported historical consolidated financial statements.

Investments in debt securities are designated as trading, available-for-sale ("AFS"), or held-to-maturity ("HTM"). Investments in debt securities are designated as HTM only if we have the positive intent and ability to hold these securities to maturity. HTM securities are reported at amortized cost in the consolidated balance sheets. Trading securities are reported at fair value, with changes in fair value included in net income. Debt securities not classified as HTM or trading are classified as AFS and are reported at fair value, with net unrealized gains and losses, net of applicable taxes, excluded from net income and included in accumulated other comprehensive income (loss) ("AOCI").

Equity securities with readily determinable fair values are carried at fair value, with changes in fair value included in net income. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment.

The Company classifies its investment securities portfolio into the following major security types: mortgage-backed securities ("MBS"), other debt securities and equity securities. The Company’s MBS portfolio is comprised primarily of residential MBS issued by United States of America ("U.S.") government entities and agencies. These securities are either explicitly or implicitly guaranteed by an agency of the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The remainder of the MBS portfolio are commercial MBS issued by U.S government entities and agencies (which there is no minimum credit rating), non-agency residential MBS (which shall meet a minimum credit rating of AAA) and non-agency commercial MBS (which shall meet a minimum credit rating of BBB and meet minimum internal credit guidelines).

The Company’s other debt securities portfolio is comprised of obligations issued by U.S. government entities and agencies, obligations issued by states and political subdivisions (which shall meet a minimum credit rating of BBB), and corporate bonds (which shall meet a minimum credit rating of BBB-).

Interest income on investment securities includes amortization of premiums and accretion of discounts. We amortize premiums to the earliest call date. We accrete discounts associated with investment securities using the effective interest method over the life of the respective security instrument. Gains and losses on the sale of investment securities are recorded on the trade date and determined using the specific identification method.

A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent. Interest accrued but not received for a security placed on non-accrual status is reversed against current period interest income. There were no investment securities on nonaccrual status as of September 30, 2020 and the Company did not reverse any accrued interest against interest income during the three and nine months ended September 30, 2020.

AFS debt securities in an unrealized loss position are evaluated for impairment at least quarterly. For AFS debt securities in an unrealized loss position, the Company first assesses whether or not it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the investment security’s amortized cost basis is written down to fair value through net income.

For AFS debt securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In conducting this assessment for debt securities in an unrealized loss position, management evaluates the extent to which fair value is less than amortized cost, any changes to the rating of the security by a

rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the investment security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an ACL is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an ACL is recognized in AOCI.

As of September 30, 2020, the declines in market values of our AFS debt securities were primarily attributable to changes in interest rates and volatility in the financial markets. Because we have no intent to sell securities in an unrealized loss position and it is not more likely than not that we will be required to sell such securities before recovery of its amortized cost basis, we do not believe a credit loss exists and an ACL was not recorded.

The Company has made a policy election to exclude accrued interest receivable from the amortized cost basis of debt securities and report accrued interest receivable together with accrued interest on loans in the consolidated balance sheets. Accrued interest receivable on AFS debt securities totaled $4.2 million as of September 30, 2020. Accrued interest receivable on AFS debt securities is excluded from the estimate of credit losses.

Management measures expected credit losses on HTM debt securities on a collective basis by major security type. For pools of such securities with common risk characteristics, the historical lifetime probability of default and severity of loss in the event of default is derived or obtained from external sources. Expected credit losses for these securities are estimated using a loss rate methodology which considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts.

Expected credit loss on each security in the HTM portfolio that do not share common risk characteristics with any of the pools of debt securities is individually measured based on net realizable value, or the difference between the discounted value of the expected future cash flows, based on the original effective interest rate, and the recorded amortized cost basis of the security.

We are a member of the Federal Home Loan Bank of Des Moines (the "FHLB"). The bank is required to obtain and hold a specific number of shares of capital stock of the FHLB equal to the sum of a membership investment requirement and an activity-based investment requirement. The securities are reported at cost and are presented separately in the consolidated balance sheets.

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, net of the ACL. Amortized cost is the unpaid principal amount outstanding, net of unamortized purchase premiums and discounts, unamortized deferred loan origination fees and costs and cumulative principal charge-offs. Purchase premiums and discounts are generally amortized into interest income over the contractual terms of the underlying loans using the effective interest method. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income over the life of the related loan as an adjustment to yield and are amortized using the interest method over the contractual term of the loan, adjusted for actual prepayments. Deferred loan fees and costs on loans paid in full are recognized as a component of interest income on loans.

Interest income on loans is accrued at the contractual rate of interest on the unpaid principal balance. Accrued interest receivable on loans totaled $17.3 million at September 30, 2020 and is reported together with accrued interest on AFS debt securities on the consolidated balance sheets. Upon adoption of ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” the Company made the accounting policy election to not measure an estimate of credit losses on accrued interest receivable as the Company writes off any uncollectible accrued interest receivable in a timely manner. The Company believes COVID-19 modified loans have distinct risk characteristics that cause

them to be monitored and assessed for credit risk differently than their unmodified counterparts. Thus, in the third quarter of 2020, the Company elected to measure a reserve on the accrued interest receivable for loans on active payment forbearance or deferral. As a result, during the third quarter of 2020, the Company recorded a reserve of $0.2 million against accrued interest receivable with the offset recorded to provision for credit losses.

The Company determines delinquency status by considering the number of days full payments required by the contractual terms of the loan are past due. Loans are generally placed on nonaccrual status when principal and/or interest payments are 90 days past due, or earlier should management determine that the borrowers will be unable to meet contractual principal and/or interest obligations, unless the loans are well-secured and in the process of collection. When a loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income should management determine that the collectability of such accrued interest is doubtful. All subsequent receipts are applied to principal outstanding and no interest income is recognized unless the financial condition and payment record of the borrowers warrant such recognition and the loan is restored to accrual status. A nonaccrual loan may be restored to an accrual basis when principal and interest payments are current for a predetermined period, normally at least six months, and full payment of principal and interest is reasonably assured.

A loan is accounted for and reported as a TDR when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) the Company grants a concession to the borrower experiencing financial difficulty that it would not otherwise consider for a borrower or transaction with similar credit risk characteristics. A restructuring that results in only an insignificant delay in payment is not considered a concession. A delay may be considered insignificant if the payments subject to the delay are insignificant relative to the unpaid principal or collateral value and the contractual amount due, or the delay in timing of the restructured payment period is insignificant relative to the frequency of payments, the debt’s original contractual maturity or original expected duration.

TDRs that are performing and on accrual status as of the date of the modification remain on accrual status. TDRs that are nonperforming as of the date of modification generally remain as nonaccrual until the prospect of future payments in accordance with the modified loan agreement is reasonably assured, generally demonstrated when the borrower maintains compliance with the restructured terms for a predetermined period, normally at least six months. TDRs with temporary below-market concessions remain designated as a TDR regardless of the accrual or performance status until the loan is paid off.

Expected credit losses are estimated on a collective (pool) basis when they share similar risk characteristics. If a TDR financial asset shares similar risk characteristics with other financial assets, it is evaluated with those other financial assets on a collective basis. If it does not share similar risk characteristics with other financial assets, it is evaluated individually. The Company’s ACL reflects all effects of a TDR when an individual asset is specifically identified as a reasonably expected TDR. The Company has determined that a TDR is reasonably expected no later than the point when the lender concludes that modification is the best course of action and it is at least reasonably possible that the troubled borrower will accept some form of concession from the lender to avoid a default. Reasonably expected TDRs and executed TDRs are evaluated to determine the required ACL using the same method as all other loans held for investment, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the ACL is determined by discounting the expected future cash flows at the original interest rate of the loan. Based on the underlying risk characteristics, TDRs performing in accordance with their modified contractual terms may be collectively evaluated.

In April 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation, (“the agencies”) issued a revised interagency statement encouraging financial institutions to work with customers affected by the COVID-19 pandemic and providing additional information regarding loan modifications. The revised interagency statement clarifies the interaction between the interagency statement issued on March 22, 2020 and the temporary relief provided by Section 4013 of the CARES Act. Section 4013 allows financial institutions to suspend the requirements to classify certain loan modifications as TDRs. The revised statement also provides supervisory interpretations on past due and nonaccrual regulatory reporting of loan modification programs and regulatory capital. Section 4013 and the interagency guidance are being applied by the Company to loan modifications made related to the COVID-19 pandemic as eligible and appropriate. The application of the guidance reduced the number of TDRs that were reported. Future TDRs are indeterminable and will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities and other third parties in response to the pandemic.

Under the current expected credit loss methodology, the ACL for loans is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. Our policy is to charge off a loan in the period in which the loan is deemed to be uncollectible and all interest previously accrued but not collected is reversed against current period interest income. We consider a loan to be uncollectible when it is probable that a loss has been incurred and the Company can make a reasonable estimate of the loss. In these instances, the likelihood of and/or timeframe for recovery of the amount due is uncertain, weak, or protracted. Subsequent receipts, if any, are credited first to the remaining principal, then to the ACL for loans as recoveries, and finally to unaccrued interest.

The ACL for loans represents management's estimate of all expected credit losses over the expected life of our existing loan portfolio. Management estimates the ACL balance using relevant available information about the collectability of cash flows, from internal and external sources, including historical information relating to past events, current conditions, and reasonable and supportable forecasts of future economic conditions. When the Company is unable to forecast future economic events, management may revert to historical information.

Historical credit loss experience provides the basis for the Company’s expected credit loss estimate. Adjustments to historical loss information may be made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, or when historical asset terms do not reflect the contractual terms of the financial assets being evaluated.

The ACL methodology may also consider other adjustments to address changes in conditions, trends, and circumstances such as local industry changes that could have a significant impact on the risk profile of the loan portfolio and provide for losses in the loan portfolio that may not be reflected and/or captured in the historical loss data. These factors include: lending policies, imprecision in forecasting future economic conditions, loan profile, lending staff, problem loan trends, loan review, collateral, credit concentration and other internal and external factors.

The Company uses the Moody’s Analytics forecasting service for the economic forecast considered in its ACL methodology. The Moody’s Analytics forecast includes both National and Hawaii specific economic indicators. The Moody’s forecast is widely used in the industry and is reasonable and supportable. The Moody’s Analytics forecast is updated at least monthly and includes a variety of economic scenarios. Generally the Company will use the most recent consensus forecast from Moody’s as of the balance sheet date. During times of economic and market volatility or instability, the Company may include a qualitative factor for forecast imprecision that factors in other potential economic scenarios available by Moody’s Analytics or may apply overrides to its statistical models to enhance the reasonableness of its loss estimates.

The ACL is measured on a collective or pool basis when similar risk characteristics exist. The Company segments its portfolio generally by Federal Financial Institutions Examination Council ("FFIEC") Call Report codes. Loan pools are further segmented by risk utilizing risk ratings or bands of payment delinquency (including TDR or non-accrual status), depending on what is most appropriate for each segment. Additional sub-segmentation may be utilized to identify groups of loans with unique risk characteristics relative to the rest of the portfolio.

The Company relies on a third-party platform which offers multiple methodologies to measure historical life-of-loan losses. The Company has also developed statistical models internally to incorporate future economic conditions and forecast expected credit losses based on various macro-economic indicators such as unemployment and income levels.

Construction loans include both residential and commercial development projects. Each construction project is evaluated for economic viability and construction loans pose higher credit risks than typical secured loans. Financial strength of the borrower, completion risk (the risk that the project will not be completed on time and within budget) and geographic location are the predominant risk characteristics of this segment.

Commercial real estate loans are secured by commercial properties. The predominant risk characteristic of this segment is operating risk, which is the risk that the borrower will be unable to generate sufficient cash flows from the operation of the property. Interest rate conditions and the commercial real estate market through economic cycles also impact risk levels.

Multi-family mortgage loans can comprise multi-building properties with extensive amenities to a single building with no amenities. The primary risk characteristic of this segment is operating risk or the ability to generate sufficient rental cash flows from the operation of the property within the owner’s strategy and resources.

Loans in this category consist primarily of term loans and lines of credit to small and middle-market businesses and professionals. The predominant risk characteristics of this segment are the cash flows of the business we lend to, global cash flows including guarantor liquidity, as well as economic and market conditions. The borrower’s business is typically regarded as the principal source of repayment, though our underwriting policy and practice generally requires secondary sources of support or collateral to mitigate risk.

Home equity lines of credit include fixed or floating interest rate loans and are secured by single-family owner-occupied primary residences in Hawaii. They are underwritten based on a minimum FICO score, maximum debt-to-income ratio, and maximum combined loan-to-value ratio. Home equity lines of credit are monitored based on credit score, delinquency, end of draw period and maturity.

Residential mortgage loans include fixed-rate and adjustable-rate loans primarily secured by single-family owner-occupied primary residences in Hawaii. Economic conditions such as unemployment levels, future changes in interest rates and other market factors impact the level of credit risk inherent in the portfolio.

The PD/LGD calculation is based on a cohort methodology whereby loans in the same cohort are tracked over time to identify defaults and corresponding losses. PD/LGD analysis requires a portfolio segmented into pools, and we elected to then further sub-segment by risk characteristics such as Risk Rating, days past due, delinquency counters, TDR status and Nonaccrual status to measure losses accurately. PD measures the count or dollar amount of loans that defaulted in a given cohort. LGD measures the losses related to the loans that defaulted. Total loss rate is calculated using the formula ‘PD times LGD’.

Migration analysis is a cohort-based approach that measures cumulative net charge-offs over a defined time-horizon to calculate a loss rate that will be applied to the loan pool. Migration analysis requires the portfolio to be segmented into pools then further sub-segmented by risk characteristics such as risk rating, days past due, delinquency counters, TDR status and Nonaccrual status to measure loss rates accurately. The key inputs to run a migration analysis are the length and frequency of the migration period, the dates for the migration periods to start and the number of migration periods used for the analysis. For each migration period, the analysis will determine the outstanding balance in each segment and/or sub-segment at the start of each period. These loans will then be followed for the length of the migration period to identify the amount of associated charge-offs and recoveries. A loss rate for each migration period is calculated using the formula 'net charge-offs over the period divided by beginning loan balance.

Under the WARM methodology, lifetime losses are calculated by determining the remaining life of the loan pool and then applying a loss rate which includes a forecast component over this remaining life. The methodology considers historical loss experience as well as a loss forecast expectation to estimate credit losses for the remaining balance of the loan pool. The calculated loss rate is applied to the contractual term (adjusted for prepayments) to determine the loan pool’s current expected credit losses.

If a loan ceases to share similar risk characteristics with other loans in its segment, it will be moved to a different pool sharing similar risk characteristics. Loans that do not share risk characteristics are evaluated on an individual basis based on the fair value of the collateral or other approaches such as discounted cash flow (“DCF”) techniques. Loans evaluated individually are not included in the collective evaluation.

Expected credit losses are estimated over the contractual term of the loans and are adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company. If such renewal options or extensions are present, these options are evaluated in determining the contractual term.

The Company maintains a separate and distinct reserve for off-balance-sheet credit exposures which is included in other liabilities on the Company’s consolidated balance sheets. The Company estimates the amount of expected losses by calculating a commitment usage factor for letters of credit, non-revolving lines of credit, and revolving lines of credit over the remaining life during which the Company is exposed to credit risk via a contractual obligation to extend credit.

Letters of credit are generally unlikely to advance since they are typically in place only to ensure various forms of performance of the borrowers. Many of the letters of credit are cash secured. Non-revolving lines of credit are determined to be likely to advance as these are typically construction lines. Meanwhile, the likelihood of revolving lines of credit advancing varies with each individual borrower. Therefore, the future usage of each line was estimated based on the average line utilization of the revolving line of credit portfolio as a whole.

The estimate also applies the loss factors for each loan type used in the ACL for loans methodology, which is based on historical losses, economic conditions and reasonable and supportable forecasts. The reserve for off-balance sheet credit exposures is adjusted as a provision for off-balance sheet credit exposures in other operating expense.

PCD financial assets, if any, are recorded at the amount paid. An ACL for PCD financial assets will be determined using the same methodology as other financial assets. The initial ACL determined on a collective basis is allocated to individual financial assets. The sum of the financial asset’s purchase price and the ACL becomes its initial amortized cost. The difference between the initial amortized costs basis and the par value of the financial asset is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the ACL are recorded through the provision for credit losses.
