CY2022	us-gaap	Use Of Estimates UseOfEstimates	The Company prepares its consolidated financial statements in conformity with accounting principles generally accepted in the United States and prevailing practices within the banking industry. The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of income, gains, expenses, and losses during the reporting periods. Actual results could differ from those estimates. Significant estimates include the allowance for credit losses (“ACL”), valuation of goodwill and other intangibles, valuation of other real estate owned (“OREO”), valuation of mortgage servicing rights (“MSRs”), and fair value disclosures.

CY2022	us-gaap	Concentration Risk Credit Risk ConcentrationRiskCreditRisk	Substantially all of the Company’s business is derived from the Anchorage, Matanuska-Susitna Valley, Fairbanks, Kenai Peninsula, Nome, and Southeast areas of Alaska. As such, the Company’s growth and operations depend upon the economic conditions of Alaska and these specific markets. These areas rely primarily upon the natural resources industries, particularly oil production, as well as tourism, government and U.S. military spending for their economic success. A significant majority of the unrestricted revenues of the Alaska state government are currently funded through various taxes and royalties on the oil industry. The Company’s business is and will remain sensitive to economic factors that relate to these industries and local and regional business conditions. As a result, local or regional economic downturns, or downturns that disproportionately affect one or more of the key industries in regions served by the Company, may have a more pronounced effect upon its business than they might on an institution that is less geographically concentrated. The extent of the future impact of these events on economic and business conditions cannot be predicted; however, prolonged or acute fluctuations could have a material and adverse impact upon the Company’s results of operation and financial condition.
