Significant Accounting Policies	NOTE 1 Significant Accounting Policies Organization Alerus Financial Corporation, or the Company, is a financial holding company organized under the laws of the state of Delaware. The Company and its subsidiaries operate as a diversified financial services company headquartered in Grand Forks, North Dakota. Through its subsidiary, Alerus Financial, National Association, or the Bank, the Company provides financial solutions to businesses and consumers through four distinct business lines—banking, retirement and benefit services, wealth management, and mortgage. Basis of Presentation The accompanying unaudited consolidated financial statements and notes thereto of the Company have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission, or SEC, and conform to practices within the banking industry and include all of the information and disclosures required by generally accepted accounting principles in the United States of America, or GAAP, for interim financial reporting. The accompanying unaudited consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for a fair presentation of financial results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results for the full year or any other period. The Company has also evaluated all subsequent events for potential recognition and disclosure through the date of the filing of this Quarterly Report on Form 10-Q. These interim unaudited financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto as of and for the year ended December 31, 2022, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 13, 2023. Principles of Consolidation The accompanying unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. The Company’s principal operating subsidiary is the Bank. In the normal course of business, the Company may enter into a transaction with a variable interest entity or VIE. VIE’s are legal entities whose investors lack the ability to make decisions about the entity’s activities, or whose equity investors do not have the right to receive the residual returns of the entity. The applicable accounting guidance requires the Company to perform ongoing quantitative and qualitative analysis to determine whether it must consolidate any VIE. The Company does not have any ownership interest in, or exert any control, over any VIE, and thus no VIE’s are included in the consolidated financial statements. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term include the valuation of investment securities, determination of the allowance for credit losses, valuation of reporting units for the purpose of testing goodwill and other intangible assets for impairment, valuation of deferred tax assets, and fair values of financial instruments. Reclassifications Certain items previously reported have been reclassified to conform to the current period’s reporting format. Such reclassifications did not affect net income or stockholders’ equity. Emerging Growth Company The Company qualifies as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, and may take advantage of certain exemptions from various reporting requirements that are applicable to public companies that are not emerging growth companies, including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. In addition, even if the Company complies with the greater obligations of public companies that are not emerging growth companies, the Company may avail itself of the reduced requirements applicable to emerging growth companies from time to time in the future, so long as the Company is an emerging growth company. The Company will continue to be an emerging growth company until the earliest to occur of: (1) the end of the fiscal year following the fifth anniversary of the date of the first sale of common equity securities under the Company’s Registration Statement on Form S-1, which was declared effective by the SEC on September 12, 2019; (2) the last day of the fiscal year in which the Company has $1.235 billion or more in annual revenues; (3) the date on which the Company is deemed to be a “large accelerated filer” under the Securities Exchange Act of 1934, as amended, or the Exchange Act; or (4) the date on which the Company has, during the previous three-year period, issued publicly or privately, more than $1.0 billion in non-convertible debt securities. The last year the Company qualifies as an emerging growth company is 2024. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933 for complying with new or revised accounting standards. As an emerging growth company, the Company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company elected to take advantage of the benefits of this extended transition period. Allowance for credit losses Investment securities available-for-sale. For available-for-sale investment securities in an unrealized loss position, the Company evaluates the securities to determine whether the decline in fair value below the amortized cost basis, or impairment, is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other comprehensive income (loss), net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses, or ACL, related to investment securities available-for-sale on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the ACL and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available-for-sale investment security or is 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 this situation. In evaluating available-for-sale 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. Accrued interest receivable is excluded from the estimate of credit losses. Investment securities held-to-maturity. Management measures expected credit losses on held-to-maturity investment securities on a collective basis by major security type. The Company evaluates held-to-maturity investment securities by credit rating and an external study, updated annually, that includes historical information such as probability of default and loss going back several years. Accrued interest receivable on held-to-maturity investment securities is excluded from the estimate of credit losses. Loans held for investment. Under the current expected credit loss, or CECL, accounting standard the ACL is a valuation estimated at each balance sheet date and deducted from the amortized cost basis of loans held for investment to present the net amount expected to be collected. The Company estimates the ACL based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for collection of cash and charge-offs, as well as applicable accretion or amortization of premium, discount and net deferred fees or costs. 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 the policy election to exclude accrued interest from the measurement of ACL. Expected credit losses are reflected in the ACL through a charge to provision for credit losses when the Company deems all or a portion of the financial asset will be uncollectible; the appropriate amount is written off and the ACL is reduced by the same amount. The Company applies judgement to determine when a financial asset is deemed uncollectible; however, generally, an asset will be considered uncollectible no later than when all efforts of collection have been exhausted. Subsequent recoveries, if any, are credited to the ACL when received. Upon the adoption of the CECL accounting standard, the Company elected to maintain pools of loans that were previously accounted for under ASC 310-30 and will continue to account for these pools as a unit of account. Upon the adoption of the CECL accounting standard, the ACL was determined for each pool and added to the pools’ carrying amount to establish a new amortized cost basis. Loans that do not share similar risk characteristics are evaluated on an individual basis. Management estimates the ACL using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable supportable forecasts. Historical loss experience provides the basis for estimation of expected credit losses. Adjustments to historical loss information are made for differences in the current loan-specific risk characteristics such as different underwriting standards, portfolio mix, delinquency level, or life of the loan, as well as changes in environmental conditions, levels of economic activity, unemployment rates, property values and other relevant factors. The calculation also contemplates that the Company may not be able to make or obtain such forecasts for the entire life of the financial assets and requires a reversion to historical loss information. Ongoing impacts of the CECL accounting standard will be dependent upon changes in economic conditions and forecasts, originated and acquired loan portfolio composition, credit performance trends, portfolio duration and other forecasts. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. The ACL on individually evaluated loans is recognized on the basis of the present value of expected future cash flows discounted at the effective interest rate, the fair value of collateral adjusted of estimated costs to sell, or observable market price as of the relevant date. Reserve for off-balance sheet credit exposures. In estimating expected credit losses for off-balance sheet credit exposures, the Company is required to estimate expected credit losses over the contractual period in which it is exposed to credit risk via a present contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the issuer. To be considered unconditionally cancellable for accounting purposes, the Company must have the ability to, at any time, with or without cause, refuse to extend credit under the commitment. Off-balance sheet credit exposure segments share the same risk characteristics as portfolio loans. The Company incorporates a probability of funding and utilizes the ACL loss rates to calculate the reserve. The reserve for off-balance sheet credit exposure is carried on the balance sheet in accrued expenses and other liabilities rather than as a component of the allowance. The reserve for off-balance sheet credit exposure is adjusted as a provision for off-balance sheet credit exposure reported as a component of the provision for credit loss expense in the accompanying unaudited Consolidated Statements of Income.

Allowance for credit losses

Investment securities available-for-sale. For available-for-sale investment securities in an unrealized loss position, the Company evaluates the securities to determine whether the decline in fair value below the amortized cost basis, or impairment, is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other comprehensive income (loss), net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses, or ACL, related to investment securities available-for-sale on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the ACL and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available-for-sale investment security or is 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 this situation.
