Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies The accompanying unaudited consolidated financial statements and corresponding footnotes have been prepared by Northrim BanCorp, Inc. (the “Company”) in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and with instructions to Form 10-Q under the Securities Exchange Act of 1934, as amended. The year-end Consolidated Balance Sheet data was derived from the Company's audited financial statements. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The Company owns a 100% interest in Residential Mortgage Holding Company, LLC, the parent company of Residential Mortgage, LLC (collectively "RML") and consolidates their balance sheets and income statement into its financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The Company determined that it operates in two primary operating segments: Community Banking and Home Mortgage Lending. The Company has evaluated subsequent events and transactions for potential recognition or disclosure. Operating results for the interim period ended March 31, 2021 are not necessarily indicative of the results anticipated for the year ending December 31, 2021. These consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The Company’s significant accounting policies are discussed in Note 1 to the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020. There have been no significant changes in our application of these accounting policies in 2021, except as noted below. As a result of the adoption of Accounting Standards Codification ("ASC") 326 Financial Instruments - Credit Losses on January 1, 2020, the Company has updated the following significant accounting policies. Allowance for Credit Losses - Investment Securities: For available for sale debt securities in an unrealized loss position, the Company evaluates the securities to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other comprehensive income, net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses (“ACL”) on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. The ACL may be reversed if conditions change. However, if the Company intends to sell an impaired available for sale debt security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount must be recognized in earnings with a corresponding adjustment to the security’s amortized cost basis. Because the security’s amortized cost basis is adjusted to fair value, there is no ACL in such a situation. In evaluating available for sale debt securities in unrealized loss positions for impairment and the criteria regarding its intent or requirement to sell such securities, the Company considers the extent to which fair value is less than amortized cost, whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers’ financial condition, among other factors. Changes in the ACL are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the ACL when management believes the uncollectability of an available for sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. The ACL on held to maturity securities is estimated on a collective basis by major security type. At March 31, 2021, the Company’s held to maturity securities consisted of investments in corporate bonds. Expected credit losses for these securities are estimated using a discounted cash flow ("DCF") methodology which considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Accrued interest receivable is excluded from the estimate of credit losses. Allowance for Credit Losses - Loans : Under the current expected credit loss model adopted by the Company on January 1, 2021, the allowance for credit losses on loans is a valuation allowance estimated at each balance sheet date that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. The Company estimates the ACL on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, and net deferred fees or costs, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to reverse accrued interest in a timely manner. Therefore, the Company has made a policy election to exclude accrued interest from the measurement of ACL. Expected credit losses are reflected in the ACL through a provision for or (reversal) of credit loss expense. When the Company deems all or a portion of a financial asset to be uncollectible the appropriate amount is written off and the ACL is reduced by the same amount. The Company applies judgment to determine when a financial asset is deemed uncollectible; however, generally speaking, an asset will be considered uncollectible when management believes that collection of principal is unlikely. Subsequent recoveries, if any, are credited to the ACL when received. The Company measures expected credit losses of financial assets on a collective (pool) basis, when the financial assets share similar risk characteristics. Depending on the nature and size of the pool of financial assets with similar risk characteristics, the Company uses a DCF method or a weighted average remaining life method to estimate expected credit losses quantitatively. The Company uses a DCF method for 8 of its 11 loan pools, which represent 98% of the amortized cost basis of total loans at March 31, 2021. The weighted average remaining life method is used for the remaining 3 loan pools primarily because loan level data constraints preclude the use of the DCF model. The weighted average remaining life method uses exposure at default, along with the expected credit losses adjusted for prepayments to calculate the required allowance. The Company utilizes peer historical loss data to estimate credit losses under the weighted average remaining life method. Under the DCF method, the Company utilizes complex models to obtain reasonable and supportable forecasts to calculate two predictive metrics, the probability of default ("PD") and loss given default ("LGD"). The PD measures the probability that a loan will default within a given time horizon and is an assumption derived from regression models which determine the relationship between historical defaults and certain economic variables. The Company's regression models for PD utilize the Company's actual historical loan level default data. The Company determines a reasonable and supportable forecast and applies that forecast to the regression model to estimate defaults over the forecast period. Management leverages economic projections from a reputable and independent third-party to inform its loss driver forecasts over the Company's 4 quarter forecast period. Management utilizes and forecasts Alaska unemployment as a loss driver for all of the loans pools that utilized the DCF method. Management also utilizes and forecasts either one-year percentage change in the Alaska home price index or the one-year percentage change in the national commercial real estate price index as a second loss driver depending on the nature of the underlying loan pool and how well that loss driver correlates to expected future losses. Other internal and external indicators of economic forecasts are also considered by management when developing the forecast metrics. Following the forecast period, the economic variables used to calculate PD revert to a historical average at a constant rate over an 8 quarter reversion period. Other assumptions relevant to the discounted cash flow model to derive the quantitative allowance include the LGD, which is the estimate of loss for a defaulted loan, prepayment speeds, and the discount rate applied to future cash flows. The DCF method utilizes the effective interest rate of individual assets to discount the expected credit losses over the contractual term of the loan, adjusted for prepayments. The LGD is the expected loss which would be realized presuming a default has occurred and primarily measures the value of the collateral or other secondary source of repayment related to the collateral. The Company’s estimate of the ACL reflects losses expected over the remaining contractual life of the assets. The contractual term does not consider extensions, renewals or modifications unless the Company has identified an expected troubled debt restructuring. In summary, under the DCF method the combination of adjustments for credit expectations (PD and LGD) and timing expectations (prepayment, curtailment, and time to recovery) produces an expected cash flow stream at the instrument level. Instrument effective yield is calculated, net of the impacts of prepayment assumptions, and the instrument expected cash flows are then discounted at that effective yield to produce an instrument-level net present value of expected cash flows (“NPV”). An ACL is established for the difference between the instrument’s NPV and amortized cost basis. The Company has identified the following pools of financial assets with similar risk characteristics for measuring expected credit losses under the current expected credit loss model adopted by the Company on January 1, 2021: Commercial & industrial - Commercial loans are loans for commercial, corporate and business purposes. The Company’s commercial business loan portfolio is comprised of loans for a variety of purposes and across a variety of industries. These loans include general commercial and industrial loans, loans to purchase capital equipment, and other business loans for working capital and operational purposes. Commercial loans are generally secured by accounts receivable, inventory and other business assets. Also included in commercial loans are our Paycheck Protection Program ("PPP") loans originated during 2020 and 2021. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Commercial real estate - This category of loans consists of the following loan types: Owner occupied - This category includes non-farm, non-residential real estate loans for a variety of commercial property types and purposes, including owner occupied commercial real estate loans primarily secured by commercial office or industrial buildings, warehouses or retail buildings where the owner of the building occupies the property. Repayment terms vary considerably, interest rates are fixed or variable, and are structured for full, partial, or no amortization of principal. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Non-owner occupied and multifamily - This category includes non-farm, non-residential real estate loans for a variety of commercial property types and purposes, including investment real estate loans that are primarily secured by office and industrial buildings, warehouses or retail buildings where the owner of the building does not occupy the property, non-owner occupied apartment or multifamily residential buildings, and various special purpose properties. Repayment terms vary considerably, interest rates are fixed or variable, and are structured for full, partial, or no amortization of principal. Generally, these types of loans are thought to involve a greater degree of credit risk than owner occupied commercial real estate as they are more sensitive to adverse economic conditions. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Residential real estate - This category of loans consists of the following loan types: 1-4 family residential properties secured by first liens - This category of loans includes term loans secured by first liens on residential real estate. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. 1-4 family residential properties secured by junior liens and revolving secured by 1-4 family first liens - This category of loans includes term loans primarily secured by junior liens on residential real estate and revolving credit lines that are secured by first liens on residential real estate. Home equity revolving lines of credit and home equity term loans are included in this group of loans. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. 1-4 family residential construction - This category of loans consists of loans to finance the ground up construction, improvement and/or carrying for sale after the completion of construction of 1-4 family residential properties which will secure the loan. These loans may also be secured by tracts or individual parcels of land on which 1-4 family residential properties are being constructed. The repayment of construction loans is generally dependent upon the successful completion of the improvements by the builder for the end user, or sale of the property to a third-party. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Other construction, land development, and raw land - This category of loans consists of loans to finance the ground up construction, improvement and/or carrying for sale after the completion of construction of owner occupied and non-owner occupied commercial properties, and loans secured by raw or improved land. The repayment of construction loans is generally dependent upon the successful completion of the improvements by the builder for the end user, or sale of the property to a third-party. Repayment of land secured loans are dependent upon the successful development and sale of the property, the sale of the land as is, or the outside cash flow of the owners to support the retirement of the debt. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Agricultural production, including commercial fishing - These loans are for the purpose of financing agricultural production, including growing and storing of crops, and for the purpose of financing fisheries and forestries, including loans to commercial fishermen. These loans may be secured or unsecured, but any loans for these purposes that are secured by real estate are included in a real estate category. The Company utilizes the weighted average remaining life method to quantitatively estimate credit losses for this pool. Consumer - Loans used for personal use, which may be secured or unsecured, and customer overdrafts. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Obligations of states and political subdivisions in the US - This category of loans includes all loans made to states, counties municipalities, school districts, drainage and sewer districts, and Indian tribes in the U.S. These loans maybe be secured by any type of collateral, including real estate. The Company utilizes the weighted average remaining life method to quantitatively estimate credit losses for this pool. Other - This category of loans includes all other loans that cannot properly be reported in one of the preceding categories. The Company utilizes the weighted average remaining life method to quantitatively estimate credit losses for this pool. In addition to the quantitative portion of the ACL derived using either the DCF or weighted average remaining life method, the Company also considers the effects of the following qualitative factors in its calculation of expected losses in the loan portfolio: • Lending strategy, policies, and procedures; • Quality of internal loan review; • Lending management and staff; • Trends in underlying collateral values; • Competition, legal, and regulatory changes; • Economic and business conditions including fluctuations in the price of Alaska North slope crude oil; • Changes in trends, volume and severity of adversely classified loans, nonaccrual loans, and delinquencies; • Concentration of credit; and • Changes in the nature and volume of the loan portfolio. The qualitative factor methodology is based on quantitative metrics, but also includes a high degree of subjectivity and changes in any of the metrics could have a significant impact on our calculation of the allowance. Loans that do not share risk characteristics with other loans in the portfolio are individually evaluated for expected credit losses and are not included in the collective evaluation. Loans are identified for individual evaluation during regular credit reviews of the portfolio. A loan is generally identified for individual evaluation when management determines that we will probably not be able to collect all amounts due according to the loan contract, including scheduled interest payments. When we identify a loan for individual evaluation, we measure expected credit losses using discounted cash flows, except when the sole remaining source of the repayment for the loan is the liquidation of the collateral. In these cases, we use the current fair value of the collateral, less selling costs, instead of discounted cash flows. The analysis of collateral dependent loans includes appraisals on loans secured by real property, management’s assessment of the current market, recent payment history and an evaluation of other sources of repayment. A loan that has been modified or renewed is considered a troubled debt restructuring (“TDR”) when two conditions are met: 1) the borrower is experiencing financial difficulty; and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. 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 non-performing TDRs are evaluated individually to determine the required ACL. TDRs performing in accordance with their modified contractual terms for a reasonable period of time may be included in the Company’s existing pools based on the underlying risk characteristics of the loan to measure the ACL. If we determine that the value of and individually evaluated loan is less than the recorded investment in the loan, we either recognize an allowance for credit losses specific to that loan, or charge-off the deficit balance on collateral dependent loans if it is determined that such amount represents a confirmed loss. Subsequent changes in the expected credit losses for loans evaluated individually are included within the provision for credit losses in the same manner in which the expected credit loss initially was recognized or as a reduction in the provision that would otherwise be reported. Paycheck Protection Program and other loans guaranteed by the U.S. government: With the passage of the PPP, the Company has actively participated in assisting its customers with applications for loans through the program. Loans funded through the PPP program are fully guaranteed by the U.S. government subject to certain representations and warranties. This guarantee exists at the inception of the loans and throughout the lives of the loans and was not entered into separately and apart from the loans. ASC 326 requires credit enhancements that mitigate credit losses, such as the U.S. government guarantee on PPP loans, to be considered in estimating credit losses. The guarantee is considered “embedded” and, therefore, is considered when estimating credit loss on the PPP loans and other loans guaranteed by the U.S. government. Given that the loans are fully guaranteed by the U.S. government and absent any specific loss information on any of our guaranteed loans, the Company does not carry an ACL on its PPP and other loans guaranteed by the U.S. government at March 31, 2021 or December 31, 2020. Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures: The Company enters into various types of transactions that involve financial instruments with off-balance sheet risk, including commitments to extend credit and standby letters of credit issued to meet customer financing needs. We apply the same credit standards to these commitments as in all of our lending activities and include these commitments in our lending risk evaluations. The Company’s exposure to credit loss in the event of nonperformance by the other party to commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company records an allowance for credit losses on off-balance sheet credit exposures, unless the commitments to extend credit are unconditionally cancellable, through a charge to provision for credit loss expense in the Company’s consolidated statements of income. The ACL on off-balance sheet credit exposures is estimated by loan segment at each balance sheet date under the current expected credit loss model using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur, and is included in other liabilities on the Company’s consolidated balance sheets. Purchased Receivables and related Allowance for Credit Losses: The Company purchases accounts receivable from its customers. The purchased receivables are carried at amortized cost, net of an allowance for credit losses. Management measures expected credit losses on purchased receivables by evaluating each receivable individually. Each quarter, management reviews purchased receivable asset balances compared to assets eligible for advancement of funds in order to determine the exposure to loss for the Company. Exposure is zero when outstanding balances exceed assets eligible for advancement. Management may determine that an ACL is appropriate for individual purchased receivables based on asset specific facts and circumstances. Fees charged to the customer are earned while the balances of the purchases are outstanding, which is typically less than one year. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Reclassification of Prior Year Presentation Certain prior year amounts have been reclassified for consistency with the current period presentation. These reclassifications had no effect on the reported results of operations or total shareholders' equity. Recent Accounting Pronouncements Accounting pronouncements implemented in 2021 In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (“ASU 2016-13” or “CECL”). ASU 2016-13 is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. Under ASU 2016-13 financial institutions and other organizations will use forward-looking information to better inform their credit loss estimates but will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. ASU 2016-13 requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization's portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2019, and must be applied prospectively. However, on October 16, 2019 the FASB voted to delay ASU 2016-13 for Smaller Reporting Companies. The Company has elected Small Reporting Company status, which changes the effective date for ASU 2016-13 for the Company to fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2022. Early application was permitted for specified periods. The Company elected to early adopt ASU 2016-13 on January 1, 2021 after finalizing data and model validation and our internal governance framework. The guidance was applied on a modified retrospective basis with the cumulative effect of initially applying the amendments recognized in retained earnings at January 1, 2021. However, certain provisions of the guidance are only required to be applied on a prospective basis. Results for periods beginning after January 1, 2021 and presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable US GAAP. The Company recorded a net increase in retained earnings of $2.4 million upon adoption. The transition adjustment includes a decrease in the allowance for credit losses on loans of $4.5 million, a decrease in the allowance for credit losses on purchased receivables of $73,000, and an increase in the allowance for credit losses on unfunded commitments of $1.2 million, net of the corresponding net decrease in deferred tax assets of $954,000. Accounting pronouncements to be implemented in future periods In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Report of Financial Reporting ("ASU 2020-04"). ASU 2020-04 was issued to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference London Inter-Bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. The last expedient is a one-time election to sell or transfer debt securities classified as held to maturity. The expedients are in effect from March 12, 2020, through December 31, 2022. The Company will be able to use the expedients in this guidance to manage through the transition away from LIBOR, specifically for our loan portfolio, derivative contracts, and bond portfolio. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope, ("ASU 2021-01"). The amendments in ASU 2021-01 are elective and apply to all entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The amendments clarify certain optional expedients and exceptions in Topic 848 for contract modifications apply to derivatives that are affected by the discounting transition. LIBOR is a widely-referenced benchmark rate, which is published in five currencies and a range of tenors, and seeks to estimate the cost at which banks can borrow on an unsecured basis from other banks. The administrator of LIBOR, ICE Benchmark Administration, published a consultation in December 2020 regarding its intention to cease the publication of LIBOR after December 31, 2021, with the exception of certain tenors of U.S. dollar (USD) LIBOR that it proposed would remain available for use in legacy contracts or as otherwise enumerated by financial regulators until June 30, 2023. The Company has some assets and liabilities referenced to LIBOR, such as commercial loans, derivatives, debt securities, and junior subordinated debentures. As of March 31, 2021, we had approximately $206.0 million of assets, including $128.7 million in commercial loans and $77.3 million in debt securities, and $10.3 million of liabilities in the form of our junior subordinated debentures linked to USD LIBOR. These amounts exclude derivative assets and liabilities on our consolidated balance sheet. As of March 31, 2021, the notional amount of our USD LIBOR-linked interest rate derivative contracts was $158.3 million. Of this amount, $74.0 million in notional value represent commercial loan interest rate swap agreements with commercial banking customers. An additional $74.0 million in notional value represent corresponding swap agreements with third party financial institutions that offset the commercial loan swaps. Swap agreements with third party institutions are $84.3 million, including an interest rate swap agreement for $10.3 million in notional value related to our junior subordinated debentures. Each of the USD LIBOR-linked amounts referenced above are expected to vary in future periods as current contracts expire with potential replacement contracts using an alternative reference rate. In an effort to mitigate the risks associated with a transition away from LIBOR, our Asset Liability Committee has undertaken initiatives to: (i) develop more robust fallback language and disclosures related to the LIBOR transition, (ii) develop a plan to seek to amend legacy contracts to reference such fallback language or alternative reference rates, (iii) enhance systems to support commercial loans, securities, and derivatives linked to the Secured Overnight Financing Rate and other alternative reference rates, (iv) develop and evaluate internal guidance, policies and procedures focused on the transition away from LIBOR to alternative reference rate products, and (v) prepare and disseminate internal and external communications regarding the LIBOR transition. The amendments are in effect from March 12, 2020, through December 31, 2022. ASU 2021-01 does not have a material impact on the Company's consolidated financial statements.

Consideration is given to the extent to which the fair value is less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the security for a period of time sufficient to allow for any anticipated recovery in fair value. At March 31, 2021, the Company had 22 available for sale securities in an unrealized loss position without an allowance for credit losses. At March 31, 2021, the Company had one held to maturity security in an unrealized loss position without an allowance for credit losses. Management does not have the intent to sell any of these securities and believes that it is more likely than not that the Company will not have to sell any such securities before a recovery of cost. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Accordingly, as of March 31, 2021, management believes that the unrealized losses detailed in the previous table are due to noncredit-related factors, including changes in interest rates and other market conditions, and therefore no losses have been recognized in the Company's Consolidated Statements of Income. At March 31, 2021 and December 31, 2020, $80.6 million and $77.9 million in securities were pledged for deposits and borrowings, respectively. The amortized cost and estimated fair values of debt securities at March 31, 2021, are distributed by contractual maturity as shown below. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

Loans and Allowance for Credit

Loans and Allowance for Credit Losses	3 Months Ended

Receivables [Abstract]
Loans and Allowance for Credit Losses	Loans and Allowance for Credit Losses Loans Held for Sale Loans held for sale are comprised entirely of 1-4 family residential mortgage loans as of March 31, 2021 and December 31, 2020. Loans Held for Investment The Company adopted ASU 2016-13 effective January 1, 2021. Upon adoption, the Company changed its loan segments for purposes of the calculation of the allowance for credit losses. Prior to January 1, 2021, the Company's loan segments were based on a combination of loan purpose and loan collateral.

Upon adoption, the Company established an ACL of $16.6 million. The ACL as of March 31, 2021 the ACL decreased to $14.8 million primary due to projected improvement in the economic indicators, or loss drivers, that the Company uses to calculate expected lifetime losses. The Company primarily uses the DCF method to estimate ACL for loans. The Company utilizes and forecasts unemployment in Alaska as our primary loss driver. The Company also utilizes and forecasts either the one-year percentage change in the Alaska home price index or the one-year percentage change in the national commercial real estate price index as a second loss driver depending on the nature of the underlying loan pool and how well that loss driver correlates to expected future losses. Consistent forecasts of the loss drivers are used across the loan segments. At March 31, 2021, as compared to January 1, 2021, the Company forecasted a significantly lower unemployment rate in Alaska, a slightly lower one-year percentage change in the national commercial real estate price index , and a slightly higher one-year percentage change in the Alaska home price index over the reasonable and supportable forecast period. Specifically regarding the forecasts used to calculate the March 31, 2021 ACL, management expects unemployment to remain consistent with actual levels observed in Alaska as of December 2020, which remained relatively unchanged in January and February 2021. This rate is above pre-pandemic levels over the forecast period, but is lower than rates previously projected by management.

The risk classification is a dual rating system that contemplates both probability of default and risk of loss given default. Loans are graded on a scale of 1 to 10 and, loans graded 1 – 6 are considered “pass” grade loans. Loans graded 7 or higher are considered "classified" loans. A description of the general characteristics of the AQR risk classifications are as follows: Pass grade loans – 1 through 6: The borrower demonstrates sufficient cash flow to fund debt service, including acceptable profit margins, cash flows, liquidity and other balance sheet ratios. Historic and projected performance indicates that the borrower is able to meet obligations under most economic circumstances. The Company has competent management with an acceptable track record. The category does not include loans with undue or unwarranted credit risks that constitute identifiable weaknesses. Classified loans: Special Mention – 7: A "special mention" credit has weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset at some future date. Substandard – 8: A "substandard" credit is inadequately protected by the current worth and paying capacity of the obligor or by the collateral pledged, if any. Assets so classified must have a well-defined weakness, or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that Northrim Bank will sustain some loss if the deficiencies are not corrected. Doubtful – 9: An asset classified "doubtful" has all the weaknesses inherent in one that is classified "substandard-8" with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions, and values, highly questionable and improbable. The loan has substandard characteristics, and available information suggests that it is unlikely that the loan will be repaid in its entirety. Loss – 10: An asset classified "loss" is considered uncollectible and of such little value that its continuance on the books is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset, even though partial recovery may be affected in the future. The following tables present the Company's portfolio of risk-rated loans by grade and by year of origination. Management considers the guidance in ASC 310-20 when determining whether a modification, extension, or renewal of loan constitutes a current period origination. Generally, current period renewals of credit are re-underwritten at the point of renewal and considered current period originations for purposes of the table below.

Troubled Debt Restructurings: Loans classified as TDRs totaled $6.5 million and $7.9 million at March 31, 2021 and December 31, 2020, respectively. A TDR is a loan to a borrower that is experiencing financial difficulty that has been modified from its original terms and conditions in such a way that the Company is granting the borrower a concession that it would not grant otherwise. The provisions of the CARES Act included an election to not apply the guidance on accounting for troubled debt restructurings to loan modifications, such as extensions or deferrals, related to COVID-19 made between March 1, 2020 and the earlier of (i) January 1, 2022 or (ii) 60 days after the end of the COVID-19 national emergency. The relief can only be applied to modifications for borrowers that were not more than 30 days past due as of December 31, 2019. The Company has elected to adopt these provisions of the CARES Act. As of March 31, 2021, the Company has made the following types of loan modifications related to COVID-19, which are not classified as TDRs with principal balance outstanding of: (Dollars in thousands) Interest Only Full Payment Deferral Total Portfolio loans $65,201 $23,096 $88,297 Number of modifications 21 9 30 The Company has granted a variety of concessions to borrowers in the form of loan modifications. The modifications granted can generally be described in the following categories: Rate Modification : A modification in which the interest rate is changed. Term Modification : A modification in which the maturity date, timing of payments, or frequency of payments is changed. Payment Modification : A modification in which the dollar amount of the payment is changed, or in which a loan is converted to interest only payments for a period of time is included in this category. Combination Modification : Any other type of modification, including the use of multiple categories above. AQR pass graded loans included above in the impaired loan data are loans classified as TDRs. By definition, TDRs are considered impaired loans. All of the Company's TDRs are included in impaired loans. There were no newly restructured loans that occurred during the three months ended March 31, 2021. There were $2.4 million accruing restructured loans and $4.2 million nonaccrual restructured loans that occurred prior to 2021 that are still included in portfolio loans. As discussed above, the CARES Act provided banks an option to elect to not account for certain loan modifications related to COVID-19 as TDRs as long as the borrowers were not more than 30 days past due as of December 31, 2020. The disclosed restructurings were not related to COVID-19 modifications.

There were no in charge-offs in the three months ended March 31, 2021 on loans that were newly classified as TDRs during the same period. All TDRs are also classified as impaired loans and are included in the loans individually evaluated for impairment in the calculation of the ACL. There were no TDRs with specific impairment at March 31, 2021 and December 31, 2020, respectively. The Company had no TDRs that defaulted within twelve months of restructure and defaulted during the three months ended March 31, 2021 and 2020, respectively.

Purchased Receivables [Abstract]
Purchased Receivables	Purchased Receivables Purchased receivables are carried at their principal amount outstanding, net of an allowance for credit losses, and have a maturity of less than one year. There were no purchased receivables past due at March 31, 2021 or December 31, 2020, and there were no restructured purchased receivables at March 31, 2021 or December 31, 2020. Income on purchased receivables is accrued and recognized on the principal amount outstanding using an effective interest method except when management believes doubt exists as to the collectability of the income or principal. There were no nonperforming purchased receivables as of March 31, 2021 and December 31, 2020, respectively. The following table summarizes the components of net purchased receivables for the periods indicated: (In Thousands) March 31, 2021 December 31, 2020 Purchased receivables $11,818 $13,995 Allowance for credit losses - purchased receivables — (73) Total $11,818 $13,922 The following table sets forth information regarding changes in the ACL on purchased receivables for the three-month periods ending March 31, 2021 and 2020, respectively: Three Months Ended March 31, (In Thousands) 2021 2020 Balance, beginning of period $— $94 Charge-offs — — Recoveries — — Charge-offs net of recoveries — — Benefit for purchased receivables — 5 Balance, end of period $— $99

Servicing Rights	Servicing Rights Mortgage servicing rights The following table details the activity in the Company's mortgage servicing rights ("MSR") for the three-month periods ended March 31, 2021 and 2020: Three Months Ended March 31, (In Thousands) 2021 2020 Balance, beginning of period $11,218 $11,920 Additions for new MSR capitalized 1,448 663 Changes in fair value: Due to changes in model inputs of assumptions (1) (180) (701) Other (2) (829) (229) Balance, end of period $11,657 $11,653 (1) Principally reflects changes in discount rates and prepayment speed assumptions, which are primarily affected by changes in interest rates. (2) Represents changes due to collection/realization of expected cash flows over time. The following table details information related to our serviced mortgage loan portfolio as of March 31, 2021 and December 31, 2020: (In Thousands) March 31, 2021 December 31, 2020 Balance of mortgage loans serviced for others $682,827 $683,117 MSR as a percentage of serviced loans 1.71 % 1.64 % The Company recognized servicing fees of $705,000 and $663,000 during the three-month periods ending March 31, 2021 and 2020, respectively, which includes contractually specified servicing fees and ancillary fees as a component of other noninterest income in the Company's Consolidated Statements of Income. The following table outlines the weighted average key assumptions used in measuring the fair value of MSR as of March 31, 2021 and December 31, 2020: March 31, 2021 December 31, 2020 Constant prepayment rate 12.47 % 13.05 % Discount rate 7.75 % 7.75 % Key economic assumptions and the sensitivity of the current fair value for MSR to immediate adverse changes in those assumptions at March 31, 2021 and December 31, 2020 were as follows: (In Thousands) March 31, 2021 December 31, 2020 Aggregate portfolio principal balance $682,827 $683,117 Weighted average rate of note 3.52 % 3.62 % March 31, 2021 Base 1.0% Adverse Rate Change 2.0% Adverse Rate Change Constant prepayment rate 12.47 % 24.94 % 37.40 % Discount rate 7.75 % 6.75 % 5.75 % Fair value MSR $11,657 $7,973 $5,902 Percentage of MSR 1.71 % 1.17 % 0.86 % December 31, 2020 Constant prepayment rate 13.05 % 26.11 % 38.97 % Discount rate 7.75 % 6.75 % 5.75 % Fair value MSR $11,218 $7,455 $5,404 Percentage of MSR 1.64 % 1.09 % 0.79 % The above tables show the sensitivity to market rate changes for the par rate coupon for a conventional one-to-four family Alaska Housing Finance Corporation/FNMA/FHLMC serviced home loan. The above tables reference a 100 basis point and 200 basis point decrease in discount rates. These sensitivities are hypothetical and should be used with caution as the tables above demonstrate the Company’s methodology for estimating the fair value of MSR is highly sensitive to changes in key assumptions. For example, actual prepayment experience may differ and any difference may have a material effect on MSR fair value. Changes in fair value resulting from changes in assumptions generally cannot be extrapolated because the relationship of the change in the assumption to the change in fair value may not be linear. Also, in these tables, the effects of a variation in a particular assumption on the fair value of the MSR is calculated without changing any other assumption; in reality, changes in one factor may be associated with changes in another (for example, decreases in market interest rates may provide an incentive to refinance; however, this may also indicate a slowing economy and an increase in the unemployment rate, which reduces the number of borrowers who qualify for refinancing), which may magnify or counteract the sensitivities. Thus, any measurement of MSR fair value is limited by the conditions existing and assumptions made at a particular point in time. Those assumptions may not be appropriate if they are applied to a different point in time. Commercial servicing rights The commercial servicing right asset ("CSR") has a carrying value $1.3 million at March 31, 2021 and December 31, 2020, and is included in other assets and carried at fair value on the Company's Consolidated Balance Sheets. Total commercial loans serviced for others were $278.3 million and $274.6 million at March 31, 2021 and December 31, 2020, respectively. Key assumptions used in measuring the fair value of the CSR as of March 31, 2021 and December 31, 2020 include a constant prepayment rate of 9.66% and a discount rate of 9.46%.

Leases [Abstract]
Leases	Leases The Company's lease commitments consist primarily of agreements to lease land and office facilities that it occupies to operate several of its retail branch locations that are classified as operating leases and are recognized on the balance sheet as right-of-use ("ROU") assets and lease liabilities. As of March 31, 2021, the Company has operating lease ROU assets of $11.9 million and operating lease liabilities of $11.9 million. As of December 31, 2020, the Company had operating lease ROU assets of $12.4 million and operating lease liabilities of $12.4 million. The Company did not have any agreements that are classified as finance leases as of March 31, 2021 or December 31, 2020.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue The Company's revenue is included in net interest income and other operating income on its Consolidated Statements of Income. Topic 606 in the Accounting Standards Codification ("Topic 606") includes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. The majority of our ongoing revenue-generating transactions are not subject to Topic 606, including revenue associated with financial instruments and revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with MSRs, purchased receivable income, financial guarantees, and derivatives are also not in scope of the guidance. Topic 606 is applicable to noninterest revenue streams such as deposit related fees, interchange fees, merchant services income, and commissions from the sales of mutual funds and other investments. The following presents other operating income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three-month periods ended March 31, 2021 and 2020: (In Thousands) Three Months Ended March 31, Other operating income 2021 2020 In-scope of Topic 606: Bankcard fees $740 $643 Service charges on deposit accounts 290 362 Other 370 313 Other operating income (in-scope of Topic 606) $1,400 $1,318 Other operating income (out-of-scope of Topic 606) 14,496 5,115 Total other operating income $15,896 $6,433 Gains on the sale of other real estate owned ("OREO") are also within the scope of Topic 606 and are recorded within other operating expense on the Company's Consolidated Statements of Income. Gains on the sale of OREO properties were $31,000 and $37,000 for the three months ended March 31, 2021 and 2020, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives Derivatives swaps related to community banking activities The Company enters into commercial loan interest rate swap agreements with commercial banking customers which are offset with a corresponding swap agreement with a third party financial institution ("counterparty"). The Company has agreements with its counterparties that contain provisions that provide that if the Company fails to maintain its status as a "well-capitalized" institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. These agreements also require that the Company and the counterparty collateralize any fair value shortfalls that exceed $250,000 with eligible collateral, which includes cash and securities backed with the full faith and credit of the federal government. Similarly, the Company could be required to settle its obligations under the agreement if specific regulatory events occur, such as if the Company were issued a prompt corrective action directive or a cease and desist order, or if certain regulatory ratios fall below specified levels. The Company pledged $7.1 million as of March 31, 2021 and $10.7 million as of December 31, 2020 in available for sale securities to collateralize fair value shortfalls on interest rate swap agreements. The Company had interest rate swaps related to commercial loans with an aggregate notional amount of $201.4 million and $196.0 million at March 31, 2021 and December 31, 2020, respectively. At March 31, 2021, the notional amount of interest rate swaps is made up of 17 variable to fixed rate swaps to commercial loan customers totaling $100.7 million, and 17 fixed to variable rate swaps with a counterparty totaling $100.7 million. Changes in fair value from these 17 interest rate swaps offset each other in the first three months of 2021. The Company recognized $92,000 and zero in fee income related to interest rate swaps in the three month periods ending March 31, 2021 and March 31, 2020, respectively. Interest rate swap income is recorded in other operating income on the Consolidated Statements of Income. None of these interest rate swaps are designated as hedging instruments. The Company has an interest rate swap to hedge the variability in cash flows arising out of its junior subordinated debentures, which is floating rate debt, by swapping the cash flows with an interest rate swap which receives floating and pays fixed. The Company has designated this interest rate swap as a hedging instrument. The interest rate swap effectively fixes the Company's interest payments on the $10.0 million of junior subordinated debentures held under Northrim Statutory Trust 2 at 3.72% through its maturity date. The floating rate that the dealer pays is equal to the three month LIBOR plus 1.37% which reprices quarterly on the payment date. This rate was 1.55% as of March 31, 2021. The Company pledged $2.9 million and $2.9 million in cash to collateralize initial margin and fair value exposure of our counterparty on this interest rate swap as of March 31, 2021 and December 31, 2020, respectively. Changes in the fair value of this interest rate swap are reported in other comprehensive income on the Consolidated Statements of Income. The unrealized loss on this interest rate swap was $475,000 as of March 31, 2021 and the unrealized loss was $1.7 million as of December 31, 2020. Derivatives related to home mortgage banking activities The Company also uses derivatives to hedge the risk of changes in the fair values of interest rate lock commitments. The Company enters into commitments to originate residential mortgage loans at specific rates; the value of these commitments are detailed in the table below as "interest rate lock commitments". The Company also hedges the interest rate risk associated with its residential mortgage loan commitments, which are referred to as "retail interest rate contracts" in the table below. Market risk with respect to commitments to originate loans arises from changes in the value of contractual positions due to changes in interest rates. RML had commitments to originate mortgage loans held for sale totaling $181.4 million and $150.3 million at March 31, 2021 and December 31, 2020, respectively. Changes in the value of RML's interest rate derivatives are recorded in mortgage banking income on the Consolidated Statements of Income. None of these derivatives are designated as hedging instruments.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Assets and Liabilities Measured at Fair Value on a Recurring Basis Investment securities available for sale and marketable equity securities : Fair values are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. Servicing rights: MSR and CSR are measured at fair value on a recurring basis. These assets are classified as Level 3 as quoted prices are not available. In order to determine the fair value of MSR and CSR, the present value of net expected future cash flows is estimated. Assumptions used include market discount rates, anticipated prepayment speeds, escrow calculations, delinquency rates, and ancillary fee income net of servicing costs. The model assumptions are also compared to publicly filed information from several large MSR holders, as available. Derivative instruments: The fair value of the interest rate lock commitments are estimated using quoted or published market prices for similar instruments, adjusted for factors such as pull-through rate assumptions based on historical information, where appropriate. The pull-through rate assumptions are considered Level 3 valuation inputs and are significant to the interest rate lock commitment valuation; as such, the interest rate lock commitment derivatives are classified as Level 3. Interest rate contracts are valued in a model, which uses as its basis a discounted cash flow technique incorporating credit valuation adjustments to reflect nonperformance risk in the measurement of fair value. Although the Company has determined that the majority of inputs used to value its interest rate derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of March 31, 2021, the Company has assessed the significance of the impact of these adjustments on the overall valuation of its interest rate positions and has determined that they are not significant to the overall valuation of its interest rate derivatives. As a result, the Company has classified its interest rate derivative valuations in Level 2 of the fair value hierarchy. Commitments to extend credit and standby letters of credit : The fair value of commitments is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligation with the counterparties at the reporting date. Assets Subject to Nonrecurring Adjustment to Fair Value The Company is also required to measure certain assets such as equity method investments, goodwill, intangible assets, impaired loans, and OREO at fair value on a nonrecurring basis in accordance with GAAP. Any nonrecurring adjustments to fair value usually result from the write-down of individual assets. The Company uses either in-house evaluations or external appraisals to estimate the fair value of OREO and impaired loans as of each reporting date. In-house appraisals are considered Level 3 inputs and external appraisals are considered Level 2 inputs. The Company’s determination of which method to use is based upon several factors. The Company takes into account compliance with legal and regulatory guidelines, the amount of the loan, the size of the assets, the location and type of property to be valued and how critical the timing of completion of the analysis is to the assessment of value. Those factors are balanced with the level of internal expertise, internal experience and market information available, versus external expertise available such as qualified appraisers, brokers, auctioneers and equipment specialists. The Company uses external sources to estimate fair value for projects that are not fully constructed as of the date of valuation. These projects are generally valued as if complete, with an appropriate allowance for cost of completion, including contingencies developed from external sources such as vendors, engineers and contractors. The Company believes that recording OREO that is not fully constructed based on as if complete values is more appropriate than recording OREO that is not fully constructed using as is values. We concluded that as-is-complete values are appropriate for these types of projects based on the accounting guidance for capitalization of project costs and subsequent measurement of the value of real estate. GAAP specifically states that estimates and cost allocations must be reviewed at the end of each reporting period and reallocated based on revised estimates. The Company adjusts the carrying value of OREO in accordance with this guidance for increases in estimated cost to complete that exceed the fair value of the real estate at the end of each reporting period. Limitations Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors.

Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements and corresponding footnotes have been prepared by Northrim BanCorp, Inc. (the “Company”) in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and with instructions to Form 10-Q under the Securities Exchange Act of 1934, as amended. The year-end Consolidated Balance Sheet data was derived from the Company's audited financial statements. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The Company owns a 100% interest in Residential Mortgage Holding Company, LLC, the parent company of Residential Mortgage, LLC (collectively "RML") and consolidates their balance sheets and income statement into its financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The Company determined that it operates in two primary operating segments: Community Banking and Home Mortgage Lending. The Company has evaluated subsequent events and transactions for potential recognition or disclosure. Operating results for the interim period ended March 31, 2021 are not necessarily indicative of the results anticipated for the year ending December 31, 2021. These consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.
Allowance for Credit Losses	Allowance for Credit Losses - Investment Securities: For available for sale debt securities in an unrealized loss position, the Company evaluates the securities to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other comprehensive income, net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses (“ACL”) on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. The ACL may be reversed if conditions change. However, if the Company intends to sell an impaired available for sale debt security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount must be recognized in earnings with a corresponding adjustment to the security’s amortized cost basis. Because the security’s amortized cost basis is adjusted to fair value, there is no ACL in such a situation. In evaluating available for sale debt securities in unrealized loss positions for impairment and the criteria regarding its intent or requirement to sell such securities, the Company considers the extent to which fair value is less than amortized cost, whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers’ financial condition, among other factors. Changes in the ACL are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the ACL when management believes the uncollectability of an available for sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. The ACL on held to maturity securities is estimated on a collective basis by major security type. At March 31, 2021, the Company’s held to maturity securities consisted of investments in corporate bonds. Expected credit losses for these securities are estimated using a discounted cash flow ("DCF") methodology which considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Accrued interest receivable is excluded from the estimate of credit losses. Allowance for Credit Losses - Loans : Under the current expected credit loss model adopted by the Company on January 1, 2021, the allowance for credit losses on loans is a valuation allowance estimated at each balance sheet date that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. The Company estimates the ACL on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, and net deferred fees or costs, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to reverse accrued interest in a timely manner. Therefore, the Company has made a policy election to exclude accrued interest from the measurement of ACL. Expected credit losses are reflected in the ACL through a provision for or (reversal) of credit loss expense. When the Company deems all or a portion of a financial asset to be uncollectible the appropriate amount is written off and the ACL is reduced by the same amount. The Company applies judgment to determine when a financial asset is deemed uncollectible; however, generally speaking, an asset will be considered uncollectible when management believes that collection of principal is unlikely. Subsequent recoveries, if any, are credited to the ACL when received. The Company measures expected credit losses of financial assets on a collective (pool) basis, when the financial assets share similar risk characteristics. Depending on the nature and size of the pool of financial assets with similar risk characteristics, the Company uses a DCF method or a weighted average remaining life method to estimate expected credit losses quantitatively. The Company uses a DCF method for 8 of its 11 loan pools, which represent 98% of the amortized cost basis of total loans at March 31, 2021. The weighted average remaining life method is used for the remaining 3 loan pools primarily because loan level data constraints preclude the use of the DCF model. The weighted average remaining life method uses exposure at default, along with the expected credit losses adjusted for prepayments to calculate the required allowance. The Company utilizes peer historical loss data to estimate credit losses under the weighted average remaining life method. Under the DCF method, the Company utilizes complex models to obtain reasonable and supportable forecasts to calculate two predictive metrics, the probability of default ("PD") and loss given default ("LGD"). The PD measures the probability that a loan will default within a given time horizon and is an assumption derived from regression models which determine the relationship between historical defaults and certain economic variables. The Company's regression models for PD utilize the Company's actual historical loan level default data. The Company determines a reasonable and supportable forecast and applies that forecast to the regression model to estimate defaults over the forecast period. Management leverages economic projections from a reputable and independent third-party to inform its loss driver forecasts over the Company's 4 quarter forecast period. Management utilizes and forecasts Alaska unemployment as a loss driver for all of the loans pools that utilized the DCF method. Management also utilizes and forecasts either one-year percentage change in the Alaska home price index or the one-year percentage change in the national commercial real estate price index as a second loss driver depending on the nature of the underlying loan pool and how well that loss driver correlates to expected future losses. Other internal and external indicators of economic forecasts are also considered by management when developing the forecast metrics. Following the forecast period, the economic variables used to calculate PD revert to a historical average at a constant rate over an 8 quarter reversion period. Other assumptions relevant to the discounted cash flow model to derive the quantitative allowance include the LGD, which is the estimate of loss for a defaulted loan, prepayment speeds, and the discount rate applied to future cash flows. The DCF method utilizes the effective interest rate of individual assets to discount the expected credit losses over the contractual term of the loan, adjusted for prepayments. The LGD is the expected loss which would be realized presuming a default has occurred and primarily measures the value of the collateral or other secondary source of repayment related to the collateral. The Company’s estimate of the ACL reflects losses expected over the remaining contractual life of the assets. The contractual term does not consider extensions, renewals or modifications unless the Company has identified an expected troubled debt restructuring. In summary, under the DCF method the combination of adjustments for credit expectations (PD and LGD) and timing expectations (prepayment, curtailment, and time to recovery) produces an expected cash flow stream at the instrument level. Instrument effective yield is calculated, net of the impacts of prepayment assumptions, and the instrument expected cash flows are then discounted at that effective yield to produce an instrument-level net present value of expected cash flows (“NPV”). An ACL is established for the difference between the instrument’s NPV and amortized cost basis. The Company has identified the following pools of financial assets with similar risk characteristics for measuring expected credit losses under the current expected credit loss model adopted by the Company on January 1, 2021: Commercial & industrial - Commercial loans are loans for commercial, corporate and business purposes. The Company’s commercial business loan portfolio is comprised of loans for a variety of purposes and across a variety of industries. These loans include general commercial and industrial loans, loans to purchase capital equipment, and other business loans for working capital and operational purposes. Commercial loans are generally secured by accounts receivable, inventory and other business assets. Also included in commercial loans are our Paycheck Protection Program ("PPP") loans originated during 2020 and 2021. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Commercial real estate - This category of loans consists of the following loan types: Owner occupied - This category includes non-farm, non-residential real estate loans for a variety of commercial property types and purposes, including owner occupied commercial real estate loans primarily secured by commercial office or industrial buildings, warehouses or retail buildings where the owner of the building occupies the property. Repayment terms vary considerably, interest rates are fixed or variable, and are structured for full, partial, or no amortization of principal. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Non-owner occupied and multifamily - This category includes non-farm, non-residential real estate loans for a variety of commercial property types and purposes, including investment real estate loans that are primarily secured by office and industrial buildings, warehouses or retail buildings where the owner of the building does not occupy the property, non-owner occupied apartment or multifamily residential buildings, and various special purpose properties. Repayment terms vary considerably, interest rates are fixed or variable, and are structured for full, partial, or no amortization of principal. Generally, these types of loans are thought to involve a greater degree of credit risk than owner occupied commercial real estate as they are more sensitive to adverse economic conditions. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Residential real estate - This category of loans consists of the following loan types: 1-4 family residential properties secured by first liens - This category of loans includes term loans secured by first liens on residential real estate. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. 1-4 family residential properties secured by junior liens and revolving secured by 1-4 family first liens - This category of loans includes term loans primarily secured by junior liens on residential real estate and revolving credit lines that are secured by first liens on residential real estate. Home equity revolving lines of credit and home equity term loans are included in this group of loans. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. 1-4 family residential construction - This category of loans consists of loans to finance the ground up construction, improvement and/or carrying for sale after the completion of construction of 1-4 family residential properties which will secure the loan. These loans may also be secured by tracts or individual parcels of land on which 1-4 family residential properties are being constructed. The repayment of construction loans is generally dependent upon the successful completion of the improvements by the builder for the end user, or sale of the property to a third-party. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Other construction, land development, and raw land - This category of loans consists of loans to finance the ground up construction, improvement and/or carrying for sale after the completion of construction of owner occupied and non-owner occupied commercial properties, and loans secured by raw or improved land. The repayment of construction loans is generally dependent upon the successful completion of the improvements by the builder for the end user, or sale of the property to a third-party. Repayment of land secured loans are dependent upon the successful development and sale of the property, the sale of the land as is, or the outside cash flow of the owners to support the retirement of the debt. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Agricultural production, including commercial fishing - These loans are for the purpose of financing agricultural production, including growing and storing of crops, and for the purpose of financing fisheries and forestries, including loans to commercial fishermen. These loans may be secured or unsecured, but any loans for these purposes that are secured by real estate are included in a real estate category. The Company utilizes the weighted average remaining life method to quantitatively estimate credit losses for this pool. Consumer - Loans used for personal use, which may be secured or unsecured, and customer overdrafts. The Company utilizes the DCF method to quantitatively estimate credit losses for this pool. Obligations of states and political subdivisions in the US - This category of loans includes all loans made to states, counties municipalities, school districts, drainage and sewer districts, and Indian tribes in the U.S. These loans maybe be secured by any type of collateral, including real estate. The Company utilizes the weighted average remaining life method to quantitatively estimate credit losses for this pool. Other - This category of loans includes all other loans that cannot properly be reported in one of the preceding categories. The Company utilizes the weighted average remaining life method to quantitatively estimate credit losses for this pool. In addition to the quantitative portion of the ACL derived using either the DCF or weighted average remaining life method, the Company also considers the effects of the following qualitative factors in its calculation of expected losses in the loan portfolio: • Lending strategy, policies, and procedures; • Quality of internal loan review; • Lending management and staff; • Trends in underlying collateral values; • Competition, legal, and regulatory changes; • Economic and business conditions including fluctuations in the price of Alaska North slope crude oil; • Changes in trends, volume and severity of adversely classified loans, nonaccrual loans, and delinquencies; • Concentration of credit; and • Changes in the nature and volume of the loan portfolio. The qualitative factor methodology is based on quantitative metrics, but also includes a high degree of subjectivity and changes in any of the metrics could have a significant impact on our calculation of the allowance. Loans that do not share risk characteristics with other loans in the portfolio are individually evaluated for expected credit losses and are not included in the collective evaluation. Loans are identified for individual evaluation during regular credit reviews of the portfolio. A loan is generally identified for individual evaluation when management determines that we will probably not be able to collect all amounts due according to the loan contract, including scheduled interest payments. When we identify a loan for individual evaluation, we measure expected credit losses using discounted cash flows, except when the sole remaining source of the repayment for the loan is the liquidation of the collateral. In these cases, we use the current fair value of the collateral, less selling costs, instead of discounted cash flows. The analysis of collateral dependent loans includes appraisals on loans secured by real property, management’s assessment of the current market, recent payment history and an evaluation of other sources of repayment. A loan that has been modified or renewed is considered a troubled debt restructuring (“TDR”) when two conditions are met: 1) the borrower is experiencing financial difficulty; and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. 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 non-performing TDRs are evaluated individually to determine the required ACL. TDRs performing in accordance with their modified contractual terms for a reasonable period of time may be included in the Company’s existing pools based on the underlying risk characteristics of the loan to measure the ACL. If we determine that the value of and individually evaluated loan is less than the recorded investment in the loan, we either recognize an allowance for credit losses specific to that loan, or charge-off the deficit balance on collateral dependent loans if it is determined that such amount represents a confirmed loss. Subsequent changes in the expected credit losses for loans evaluated individually are included within the provision for credit losses in the same manner in which the expected credit loss initially was recognized or as a reduction in the provision that would otherwise be reported. Paycheck Protection Program and other loans guaranteed by the U.S. government: With the passage of the PPP, the Company has actively participated in assisting its customers with applications for loans through the program. Loans funded through the PPP program are fully guaranteed by the U.S. government subject to certain representations and warranties. This guarantee exists at the inception of the loans and throughout the lives of the loans and was not entered into separately and apart from the loans. ASC 326 requires credit enhancements that mitigate credit losses, such as the U.S. government guarantee on PPP loans, to be considered in estimating credit losses. The guarantee is considered “embedded” and, therefore, is considered when estimating credit loss on the PPP loans and other loans guaranteed by the U.S. government. Given that the loans are fully guaranteed by the U.S. government and absent any specific loss information on any of our guaranteed loans, the Company does not carry an ACL on its PPP and other loans guaranteed by the U.S. government at March 31, 2021 or December 31, 2020. Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures: The Company enters into various types of transactions that involve financial instruments with off-balance sheet risk, including commitments to extend credit and standby letters of credit issued to meet customer financing needs. We apply the same credit standards to these commitments as in all of our lending activities and include these commitments in our lending risk evaluations. The Company’s exposure to credit loss in the event of nonperformance by the other party to commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company records an allowance for credit losses on off-balance sheet credit exposures, unless the commitments to extend credit are unconditionally cancellable, through a charge to provision for credit loss expense in the Company’s consolidated statements of income. The ACL on off-balance sheet credit exposures is estimated by loan segment at each balance sheet date under the current expected credit loss model using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur, and is included in other liabilities on the Company’s consolidated balance sheets.
Reclassification of Prior Year Presentation	Reclassification of Prior Year Presentation Certain prior year amounts have been reclassified for consistency with the current period presentation. These reclassifications had no effect on the reported results of operations or total shareholders' equity.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting pronouncements implemented in 2021 In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (“ASU 2016-13” or “CECL”). ASU 2016-13 is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. Under ASU 2016-13 financial institutions and other organizations will use forward-looking information to better inform their credit loss estimates but will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. ASU 2016-13 requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization's portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2019, and must be applied prospectively. However, on October 16, 2019 the FASB voted to delay ASU 2016-13 for Smaller Reporting Companies. The Company has elected Small Reporting Company status, which changes the effective date for ASU 2016-13 for the Company to fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2022. Early application was permitted for specified periods. The Company elected to early adopt ASU 2016-13 on January 1, 2021 after finalizing data and model validation and our internal governance framework. The guidance was applied on a modified retrospective basis with the cumulative effect of initially applying the amendments recognized in retained earnings at January 1, 2021. However, certain provisions of the guidance are only required to be applied on a prospective basis. Results for periods beginning after January 1, 2021 and presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable US GAAP. The Company recorded a net increase in retained earnings of $2.4 million upon adoption. The transition adjustment includes a decrease in the allowance for credit losses on loans of $4.5 million, a decrease in the allowance for credit losses on purchased receivables of $73,000, and an increase in the allowance for credit losses on unfunded commitments of $1.2 million, net of the corresponding net decrease in deferred tax assets of $954,000. Accounting pronouncements to be implemented in future periods In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Report of Financial Reporting ("ASU 2020-04"). ASU 2020-04 was issued to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference London Inter-Bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. The last expedient is a one-time election to sell or transfer debt securities classified as held to maturity. The expedients are in effect from March 12, 2020, through December 31, 2022. The Company will be able to use the expedients in this guidance to manage through the transition away from LIBOR, specifically for our loan portfolio, derivative contracts, and bond portfolio. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope, ("ASU 2021-01"). The amendments in ASU 2021-01 are elective and apply to all entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The amendments clarify certain optional expedients and exceptions in Topic 848 for contract modifications apply to derivatives that are affected by the discounting transition. LIBOR is a widely-referenced benchmark rate, which is published in five currencies and a range of tenors, and seeks to estimate the cost at which banks can borrow on an unsecured basis from other banks. The administrator of LIBOR, ICE Benchmark Administration, published a consultation in December 2020 regarding its intention to cease the publication of LIBOR after December 31, 2021, with the exception of certain tenors of U.S. dollar (USD) LIBOR that it proposed would remain available for use in legacy contracts or as otherwise enumerated by financial regulators until June 30, 2023. The Company has some assets and liabilities referenced to LIBOR, such as commercial loans, derivatives, debt securities, and junior subordinated debentures. As of March 31, 2021, we had approximately $206.0 million of assets, including $128.7 million in commercial loans and $77.3 million in debt securities, and $10.3 million of liabilities in the form of our junior subordinated debentures linked to USD LIBOR. These amounts exclude derivative assets and liabilities on our consolidated balance sheet. As of March 31, 2021, the notional amount of our USD LIBOR-linked interest rate derivative contracts was $158.3 million. Of this amount, $74.0 million in notional value represent commercial loan interest rate swap agreements with commercial banking customers. An additional $74.0 million in notional value represent corresponding swap agreements with third party financial institutions that offset the commercial loan swaps. Swap agreements with third party institutions are $84.3 million, including an interest rate swap agreement for $10.3 million in notional value related to our junior subordinated debentures. Each of the USD LIBOR-linked amounts referenced above are expected to vary in future periods as current contracts expire with potential replacement contracts using an alternative reference rate. In an effort to mitigate the risks associated with a transition away from LIBOR, our Asset Liability Committee has undertaken initiatives to: (i) develop more robust fallback language and disclosures related to the LIBOR transition, (ii) develop a plan to seek to amend legacy contracts to reference such fallback language or alternative reference rates, (iii) enhance systems to support commercial loans, securities, and derivatives linked to the Secured Overnight Financing Rate and other alternative reference rates, (iv) develop and evaluate internal guidance, policies and procedures focused on the transition away from LIBOR to alternative reference rate products, and (v) prepare and disseminate internal and external communications regarding the LIBOR transition. The amendments are in effect from March 12, 2020, through December 31, 2022. ASU 2021-01 does not have a material impact on the Company's consolidated financial statements.
