Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Summary of Significant Accounting Policies	Nature of Operations and Summary of Significant Accounting Policies General Glacier Bancorp, Inc. (“Company”) is a Montana corporation headquartered in Kalispell, Montana. The Company provides a full range of banking services to individuals and businesses in Montana, Idaho, Utah, Washington, Wyoming, Colorado, Arizona and Nevada through its wholly-owned bank subsidiary, Glacier Bank (“Bank”). The Company offers a wide range of banking products and services, including: 1) retail banking; 2) business banking; 3) real estate, commercial, agriculture and consumer loans; and 4) mortgage origination and loan servicing. The Company serves individuals, small to medium-sized businesses, community organizations and public entities. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary for a fair presentation of the results for the interim periods. All such adjustments are of a normal recurring nature. These interim financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements and they should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. Operating results for the six months ended June 30, 2023 are not necessarily indicative of the results anticipated for the year ending December 31, 2023. The condensed consolidated statement of financial condition of the Company as of December 31, 2022 has been derived from the audited consolidated statements of the Company as of that date. The Company is a defendant in legal proceedings arising in the normal course of business. In the opinion of management, the disposition of pending litigation will not have a material affect on the Company’s consolidated financial position, results of operations or liquidity. Material estimates that are particularly susceptible to significant change include: 1) the determination of the allowance for credit losses (“ACL” or “allowance”) on loans; 2) the valuation of debt securities; 3) the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans; and 4) the evaluation of goodwill impairment. For the determination of the ACL on loans and real estate valuation estimates, management obtains independent appraisals (new or updated) for significant items. Estimates relating to the investment valuations are obtained from independent third parties. Estimates relating to the evaluation of goodwill for impairment are determined based on internal calculations using independent party inputs. Principles of Consolidation The consolidated financial statements of the Company include the parent holding company and the Bank, which consists of seventeen bank divisions and a corporate division. The corporate division includes the Bank’s investment portfolio, wholesale borrowings and other centralized functions. The Bank divisions operate under separate names, management teams and advisory directors. The Company considers the Bank to be its sole operating segment as the Bank 1) engages in similar bank business activity from which it earns revenues and incurs expenses; 2) the operating results of the Bank are regularly reviewed by the Chief Executive Officer (“CEO”) (i.e., the chief operating decision maker) who makes decisions about resources to be allocated to the Bank; and 3) financial information is available for the Bank. All significant inter-company transactions have been eliminated in consolidation. The Bank has subsidiary interests in variable interest entities (“VIE”) for which the Bank has both the power to direct the VIE’s significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could potentially be significant to the VIE. These subsidiary interests are included in the Company’s consolidated financial statements. The Bank also has subsidiary interests in VIEs for which the Bank does not have a controlling financial interest and is not the primary beneficiary. These subsidiary interests are not included in the Company’s consolidated financial statements. For additional information on the Bank’s interest in VIEs, see Note 7. The parent holding company owns non-bank subsidiaries that have issued trust preferred securities. The trust subsidiaries are not included in the Company’s consolidated financial statements. The Company's investments in the trust subsidiaries are included in other assets on the Company's statements of financial condition. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, cash held as demand deposits at various banks and the Federal Reserve Bank (“FRB”), interest bearing deposits, federal funds sold, and liquid investments with original maturities of three months or less. The Bank is required to maintain an average reserve balance with either the FRB or in the form of cash on hand. The required reserve balance at June 30, 2023 was $0. De bt Securities Debt securities for which the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity and are carried at amortized cost. Debt securities held primarily for the purpose of selling in the near term are classified as trading securities and are reported at fair value, with unrealized gains and losses included in income. Debt securities not classified as held-to-maturity or trading are classified as available-for-sale and are reported at fair value with unrealized gains and losses, net of income taxes, as a separate component of other comprehensive income (“OCI”). Premiums and discounts on debt securities are amortized or accreted into income using a method that approximates the interest method. The objective of the interest method is to calculate periodic interest income at a constant effective yield. The Company does not have any debt securities classified as trading securities. When the Company acquires another entity, it records the debt securities at fair value. The Company reviews and analyzes the various risks that may be present within the investment portfolio on an ongoing basis, including market risk, credit risk and liquidity risk. Market risk is the risk to an entity’s financial condition resulting from adverse changes in the value of its holdings arising from movements in interest rates, foreign exchange rates, equity prices or commodity prices. The Company assesses the market risk of individual debt securities as well as the investment portfolio as a whole. Credit risk, broadly defined, is the risk that an issuer or counterparty will fail to perform on an obligation. The credit rating of a security is considered the primary credit quality indicator for debt securities. Liquidity risk refers to the risk that a security will not have an active and efficient market in which the security can be sold. A debt security is investment grade if the issuer has adequate capacity to meet its commitment over the expected life of the investment, i.e., the risk of default is low and full and timely repayment of interest and principal is expected. To determine investment grade status for debt securities, the Company conducts due diligence of the creditworthiness of the issuer or counterparty prior to acquisition and ongoing thereafter consistent with the risk characteristics of the security and the overall risk of the investment portfolio. Credit quality due diligence takes into account the extent to which a security is guaranteed by the U.S. government and other agencies of the U.S. government. The depth of the due diligence is based on the complexity of the structure, the size of the security, and takes into account material positions and specific groups of securities or stratification for analysis and review of similar risk positions. The due diligence includes consideration of payment performance, collateral adequacy, internal analyses, third party research and analytics, external credit ratings and default statistics. The Company has acquired debt securities through acquisitions and if the securities have more than insignificant credit deterioration since origination, they are designated as purchased credit-deteriorated (“PCD”) securities. An ACL is determined using the same methodology as with other debt securities. The sum of a PCD security’s fair value and associated ACL becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the debt security is a noncredit discount or premium, which is amortized into interest income over the life of the security. Subsequent changes to the ACL are recorded through provision for credit losses. For additional information relating to debt securities, see Note 2. Allowance for Credit Losses - Available-for-Sale Debt Securities For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more-likely-than-not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through other expense. For the available-for-sale securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from cred it losses or other factors. In such assessment, the Company considers the extent to which fair value is less than amortized cost, if there are any changes to the investment grade of the security by a rating agency, and if there are any adverse conditions that impact the security. If this assessment indicates a credit loss exists, the present value of the cash flows expected to be collected from the security is compared to the amortized cost basis of the s ecurity. If the present value of the cash flows expected to be collected is less than the amortized cost basis, a potential credit loss exists and an ACL is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost. Any estimated credit losses that have not been recorded through an ACL are recognized in OCI. The Company has elected to exclude accrued interest from the estimate of credit losses for available-for-sale debt securities. As part of its non-accrual policy, the Company charges-off uncollectable interest at the time it is determined to be uncollectable. Allowance for Credit Losses - Held-to-Maturity Debt Securities For estimating the allowance for held-to-maturity (“HTM”) debt securities that share similar risk characteristics with other securities, such securities are pooled based on major security type. For pools of such securities with similar risk characteristics, the historical lifetime probability of default and severity of loss in the event of default is derived or obtained from external sources and adjusted for the expected effects of reasonable and supportable forecasts over the expected lives of the securities on those historical credit losses. Expected credit losses on securities in the held-to-maturity portfolio that do not share similar risk characteristics with any of the pools of debt securities are individually measured based on net realizable value, or the difference between the discounted value of the expected future cash flows, based on the original effective interest rate, and the recorded amortized cost basis of the securities. The Company has elected to exclude accrued interest from the estimate of credit losses for held-to-maturity debt securities. As part of its non-accrual policy, the Company charges off uncollectable interest at the time it is determined to be uncollectable. Loans Held for Sale Loans held for sale generally consist of long-term, fixed rate, conforming, single-family residential real estate loans intended to be sold on the secondary market. Loans held for sale are recorded at fair value and may or may not be sold with servicing rights released. Changes in fair value are recognized in non-interest income. Fair value elections are made at the time of origination based on the Company’s fair value election policy. Loans Receivable The Company’s loan segments or classes are based on the purpose of the loan and consist of residential real estate, commercial real estate, other commercial, home equity, and other consumer loans. Loans that are intended at origination to be held-to-maturity are reported at the unpaid principal balance less net c harge-offs and adjusted for deferred fees and costs on originated loans and unamortized premiums or discounts on acquired loans. Interest income is accrued on the unpaid principal balance. Fees and costs on originated loans and premiums or discounts on acquired loans are deferred and subsequently amortized or accreted as a yield adjustment over the expected life of the loan utilizing the interest or straight-line methods. The interest method is utilized for loans with scheduled payment terms and the objective is to calculate periodic interest income at a constant effective yield. The straight-line method is utilized for revolving lines of credit or loans with no scheduled payment terms. When a loan is paid off prior to maturity, the remaining unamortized fees and costs on originated loans and unamortized premiums or discounts on acquired loans are immediately recognized as interest income. Loans that are 30 days or more past due based on payments received and applied to the loan are considered delinquent. Loans are designated non-accrual and the accrual of interest is discontinued when the collection of the contractual principal or interest is unlikely. A loan is typically placed on non-accrual when principal or interest is due and has remained unpaid for 90 days or more. When a loan is placed on non-accrual status, interest previously accrued but not collected is reversed against current period interest income. Subsequent payments on non-accrual loans are applied to the outstanding principal balance if doubt remains as to the ultimate collectability of the loan. Interest accruals are not resumed on partially charged-off impaired loans. For other loans on non-accrual, interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to both principal and interest. The Company has acquired loans through acquisitions, some of which have experienced more than insignificant credit deterioration since origination. The Company considers all acquired non-accrual loans to be PCD loans. In addition, the Company considers loans accruing 90 days or more past due or substandard loans to be PCD loans. An ACL is determined using the same methodology as other loans held for investment. The ACL determined on a collective basis is allocated to individual loans. The sum of a loan’s fair value and ACL becomes the initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the ACL are recorded through provision for credit losses. For additional information relating to loans, see Note 3. Allowance for Credit Losses - Loans Receivable The ACL for loans receivable represents management’s estimate of credit losses over the expected contractual life of the loan portfolio. The estimate is determined based on the amortized cost of the loan portfolio including the loan balance adjusted for charge-offs, recoveries, deferred fees and costs, and loan discount and premiums. Recoveries are included only to the extent that such amounts were previously charged-off. The Company has elected to exclude accrued interest from the estimate of credit losses for loans. Determining the adequacy of the allowance is complex and requires a high degree of judgment by management about the effect of matters that are inherently uncertain. Subsequent evaluations of the then-existing loan portfolio, in light of the factors then prevailing, may result in significant changes in the allowance in those future periods. The allowance is increased for estimated credit losses which are recorded as expense. The portion of loans and overdraft balances determined by management to be uncollectable are charged-off as a reduction to the allowance and recoveries of amounts previously charged-off increase the allowance. The Company’s charge-off policy is consistent with bank regulatory standards. Consumer loans generally are charged-off when the loan becomes over 120 days delinquent. Real estate acquired as a result of foreclosure or by deed-in-lieu of foreclosure is classified as other real estate owned (“OREO”) until such time as it is sold. The expected credit loss estimate process involves procedures to consider the unique characteristics of each of the Company’s loan portfolio segments, which consist of residential real estate, commercial real estate, other commercial, home equity, and other consumer loans. When computing the allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, credit and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. The Company has determined a four consecutive quarter forecasting period is a reasonable and supportable period. Expected credit loss for periods beyond reasonable and supportable forecast periods are determined based on a reversion method which reverts back to historical loss estimates over a four consecutive quarter period on a straight-line basis. Credit quality is assessed and monitored by evaluating various attributes and the results of those evaluations are utilized in underwriting new loans and the process for estimating the expected credit losses. The following paragraphs describe the risk characteristics relevant to each portfolio segment. Residential Real Estate. Residential real estate loans are secured by owner-occupied 1-4 family residences. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans is impacted by economic conditions within the Company’s market areas that affect the value of the residential property securing the loans and affect the borrowers' personal incomes. Mitigating risk factors for this loan segment include a large number of borrowers, geographic dispersion of market areas and the loans are originated for relatively smaller amounts. Commercial Real Estate . Commercial real estate loans typically involve larger principal amounts, and repayment of these loans is generally dependent on the successful operation of the property securing the loan and/or the business conducted on the property securing the loan. Credit risk in these loans is impacted by the creditworthiness of a borrower, valuation of the property securing the loan and conditions within the local economies in the Company’s diverse geographic market areas. Commercial . Commercial loans consist of loans to commercial customers for use in financing working capital needs, equipment purchases and business expansions. The loans in this category are repaid primarily from the cash flow of a borrower’s principal business operation. Credit risk in these loans is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations across the Company’s diverse geographic market areas. Home Equity . Home equity loans consist of junior lien mortgages and first and junior lien lines of credit (revolving open-end and amortizing closed-end) secured by owner-occupied 1-4 family residences. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans is impacted by economic conditions within the Company’s market areas that affect the value of the residential property securing the loans and affect the borrowers' personal incomes. Mitigating risk factors for this loan segment are a large number of borrowers, geographic dispersion of market areas and the loans are originated for terms that range from 10 to 15 years. Other Consumer . The other consumer loan portfolio consists of various short-term loans such as automobile loans and loans for other personal purposes. Repayment of these loans is primarily dependent on the personal income of the borrowers. Credit risk is driven by consumer economic factors (such as unemployment and general economic conditions in the Company’s diverse geographic market areas) and the creditworthiness of a borrower. The allowance is impacted by loan volumes, delinquency status, credit ratings, historical loss experiences, estimated prepayment speeds, weighted average lives and other conditions influencing loss expectations, such as reasonable and supportable forecasts of economic conditions. The methodology for estimating the amount of expected credit losses reported in the allowance has two basic components: 1) individual loans that do not share similar risk characteristics with other loans and the measurement of expected credit losses for such individual loans; and 2) the expected credit losses for pools of loans that share similar risk characteristics. Loans that do not Share Similar Risk Characteristics with Other Loans. For a loan that does not share similar risk characteristics with other loans, expected credit loss is measured based on the net realizable value, that is, the difference between the discounted value of the expected future cash flows, based on the original effective interest rate, and the amortized cost basis of the loan. For these loans, the expected credit loss is equal to the amount by which the net realizable value of the loan is less than the amortized cost basis of the loan (which is net of previous charge-offs and deferred loan fees and costs), except when the loan is collateral-dependent, that is, when foreclosure is probable or the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In these cases, expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. The Company has determined that non-accrual loans do not share similar risk characteristics with other loans and these loans are individually evaluated for estimated allowance for credit losses. The Company, through its credit monitoring process, may also identify other loans that do not share similar risk characteristics and individually evaluate such loans. The starting point for determining the fair value of collateral is to obtain external appraisals or evaluations (new or updated). The valuation techniques used in preparing appraisals or evaluations (new or updated) include the cost approach, income approach, sales comparison approach, or a combination of the preceding valuation techniques. The Company’s credit department reviews appraisals, giving consideration to the highest and best use of the collateral. The appraisals or evaluations (new or updated) are reviewed at least quarterly and more frequently based on current market conditions, including deterioration in a borrower’s financial condition and when property values may be subject to significant volatility. Adjustments may be made to the fair value of the collateral after review and acceptance of the collateral appraisal or evaluation (new or updated). Loans that Share Similar Risk Characteristics with other Loans. For estimating the allowance for loans that share similar risk characteristics with other loans, such loans are segregated into loan segments. Loans are designated into loan segments based on loans pooled by product types and similar risk characteristics or areas of risk concentration. In determining the ACL, the Company derives an estimated credit loss assumption from a model that categorizes loan pools based on loan type which is further segregated by the credit quality indicators. This model calculates an expected loss percentage for each loan segment by considering the non-discounted simple annual average historical loss rate of each loan segment (calculated through an “open pool” method), multiplying the loss rate by the amortized loan balance and incorporating that segment’s internally generated prepayment speed assumption and contractually scheduled remaining principal pay downs on a loan level basis. The annual historical loss rates are adjusted over a reasonable economic forecast period by a multiplier that is calculated based upon current national economic forecasts as a proportion of each segment’s historical average loss levels. The Company will then revert from the economic forecast period back to the historical average loss rate in a straight-line basis. After the reversion period, the loans will be assumed to experience their historical loss rate for the remainder of their contractual lives. The model applies the expected loss rate over the projected cash flows at the individual loan level and then aggregates the losses by loan segment in determining their quantitative allowance. The Company will also include qualitative adjustments to adjust the ACL on loan segments to the extent the current or future market conditions are believed to vary substantially from historical conditions in regards to: • lending policies and procedures; • i nternational, national, regional and local economic business conditions, developments, or environmental conditions that affect the collectability of the portfolio, including the condition of various markets; • the nature and volume of the loan portfolio including the terms of the loans; • the experience, ability, and depth of the lending management and other relevant staff; • the volume and severity of past due and adversely classified or graded loans and the volume of non-accrual loans; • the quality of our loan review system; • the value of underlying collateral for collateralized loans; • the existence and effect of any concentrations of credit, and changes in the level of concentrations; and • the effect of external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the existing portfolio. The Company regularly reviews loans in the portfolio to assess credit quality indicators and to determine the appropriate loan classification and grading in accordance with applicable bank regulations. The primary credit quality indicator for residential, home equity and other consumer loans is the days past due status, which consists of the following categories: 1) performing loans; 2) 30 to 89 days past due loans; and 3) non-accrual and 90 days or more past due loans. The primary credit quality indicator for commercial real estate and commercial loans is the Company’s internal risk rating system, which includes the following categories: 1) pass loans; 2) special mention loans; 3) substandard loans; and 4) doubtful or loss loans. Such credit quality indicators are regularly monitored and incorporated into the Company’s allowance estimate. The following paragraphs further define the internal risk ratings for commercial real estate and commercial loans. Pass Loans. These ratings represent loans that are of acceptable, good or excellent quality with very limited to no risk. Loans that do not have one of the following ratings are considered pass loans. Special Mention Loans. These ratings represent loans that are designated as special mention per the regulatory definition. Special mention loans are currently protected but are potentially weak. The credit risk may be relatively minor yet constitute an undue and unwarranted risk in light of the circumstances surrounding a specific loan. The rating may be used to identify credit with potential weaknesses that if not corrected may weaken the loan to the point of inadequately protecting the Bank’s credit position. Examples include a lack of supervision, inadequate loan agreement, condition, or control of collateral, incomplete, or improper documentation, deviations from lending policy, and adverse trends in operations or economic conditions. Substandard Loans. This rating represents loans that are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged. A loan so classified must have a well-defined weakness that jeopardizes the liquidation of the debt. These loans are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregated amount of substandard loans, does not have to exist in an individual loan classified substandard. Doubtful/Loss Loans. A loan classified as doubtful has the characteristics that make collection in full, on the basis of currently existing facts, conditions, and values, highly improbable. The possibility of loss is extremely high, but because of pending factors, which may work to the advantage and strengthening of the loan, its classification as loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral and refinancing plans. Loans are classified as loss when they are deemed to be not collectible and of such little value that continuance as an active asset of the Bank is not warranted. Loans classified as loss must be charged-off. Assignment of this classification does not mean that an asset has absolutely no recovery or salvage value, but that it is not practical or desirable to defer writing off a basically worthless asset, even though partial recovery may be attained in the future. Restructured Loans On January 1, 2023, the Company adopted FASB ASU 2022-02, Financial Instruments - Credit Losses, Troubled Debt Restructurings and Vintage Disclosures, which eliminated the accounting guidance for TDRs by creditors in Accounting Standard Codification (ASC) Subtopic 310-40, and enhanced the disclosure requirements for certain loan refinancing and restructures by creditors when a borrower is experiencing financial difficulty. The company identifies modifications to borrowers experiencing financial difficulty (“MBFD”) as a loan that has been modified for the borrower that is experiencing financial difficulties. The Company considers some of the indicators that a borrower is experiencing financial difficulty to be: currently in payment default on any of their debt, declaring bankruptcy, going concern, borrower’s securities have been delisted, and other indicators of inability to meet obligations. This list does not include all potential indicators of a borrower’s financial difficulties. The allowance for credit losses on a l oans that are considered MBFD’s are measured using the same method as all other loans held for investment. Prior to the adoption of this guidance, restructured loans were considered to be a troubled debt restructuring (“TDR”) if the creditor, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would have not otherwise considered. The allowance for credit losses on a TDR were measured using the same method as all other loans held for investment. Allowance for Credit Losses - Off-Balance Sheet Credit Exposures The Company maintains a separate allowance for credit losses for off-balance sheet credit exposures, including unfunded loan commitments. Such ACL is included in other liabilities on the Company’s statements of financial condition. The Company estimates the amount of expected losses by calculating a commitment usage factor over the contractual period for exposures and applying the loss factors used in the allowance for credit loss methodology to the results of the usage calculation to estimate the liability for credit losses related to unfunded commitments for each loan segment. No credit loss estimate is reported for off-balance sheet credit exposures that are unconditionally cancellabl

Allowance for Credit Losses - Available-For-Sale Debt Securities In assessing whether a credit loss existed on available-for-sale debt securities with unrealized losses, the Company compared the present value of cash flows expected to be collected from the debt securities with the amortized cost basis of the debt securities. In addition, the following factors were evaluated individually and collectively in determining the existence of expected credit losses: • credit ratings from Nationally Recognized Statistical Rating Organizations (“NRSRO” entities such as Standard and Poor’s [“S&P”] and Moody’s); • extent to which the fair value is less than cost; • adverse conditions, if any, specifically related to the impaired securities, including the industry and geographic area; • the overall deal and payment structure of the debt securities, including the investor entity’s position within the structure, underlying obligors, financial condition and near-term prospects of the issuer, including specific events which may affect the issuer’s operations or future earnings, and credit support or enhancements; and • failure of the issuer and underlying obligors, if any, to make scheduled payments of interest and principal. The following table summarizes available-for-sale debt securities that were in an unrealized loss position for which an ACL has not been recorded, based on the length of time the individual securities have been in an unrealized loss position. The number of available-for-sale debt securities in an unrealized position is also disclosed.

A substantial portion of such securities were issued by Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”), Government National Mortgage Association (“Ginnie Mae”) and other agencies of the U.S. government or have credit ratings issued by one or more of the NRSRO entities in the four highest credit rating categories. All of the Company’s available-for-sale debt securities with unrealized loss positions at June 30, 2023 have been determined to be investment grade. The Company did not have any past due available-for-sale debt securities as of June 30, 2023 and December 31, 2022, respectively. Accrued interest receivable on available-for-sale debt securities totaled $9,507,000 and $10,518,000 at June 30, 2023, and December 31, 2022, respectively, and was excluded from the estimate of credit losses. Based on an analysis of its available-for-sale debt securities with unrealized losses as of June 30, 2023, the Company determined the decline in value was unrelated to credit losses and was primarily the result of changes in interest rates and market spreads subsequent to acquisition. The fair value of the debt securities is expected to recover as payments are received and the debt securities approach maturity. In addition, as of June 30, 2023, management determined it did not intend to sell available-for-sale debt securities with unrealized losses, and there was no expected requirement to sell such securities before recovery of their amortized cost. As a result, no ACL was recorded on available-for-sale debt securities at June 30, 2023. As part of this determination, the Company considered contractual obligations, regulatory constraints, liquidity, capital, asset/liability management and securities portfolio objectives and whether or not any of the Company’s investment securities were managed by third-party investment funds. Allowance for Credit Losses - Held-To-Maturity Debt Securities The Company measured expected credit losses on held-to-maturity debt securities on a collective basis by major security type and NRSRO credit ratings, which is the Company’s primary credit quality indicator for state and local government securities. The estimate of expected credit losses considered historical credit loss information that was adjusted for current conditions as well as reasonable and supportable forecasts. The following table summarizes the amortized cost of held-to-maturity municipal bonds aggregated by NRSRO credit rating: (Dollars in thousands) June 30, December 31, Municipal bonds held-to-maturity S&P: AAA / Moody’s: Aaa $ 430,598 430,542 S&P: AA+, AA, AA- / Moody’s: Aa1, Aa2, Aa3 1,190,105 1,206,441 S&P: A+, A, A- / Moody’s: A1, A2, A3 37,956 37,162 Not rated by either entity 6,687 8,495 Total municipal bonds held-to-maturity $ 1,665,346 1,682,640 The Company’s municipal bonds in the held-to-maturity debt securities portfolio is primarily comprised of general obligation and revenue bonds with NRSRO ratings in the four highest credit rating categories. All of the Company’s municipal bonds that are classified as held-to-maturity debt securities at June 30, 2023 have been determined to be investment grade. Held-to-maturity debt securities included in the Company’s U.S. government and federal agency and residential mortgage-backed security categories are issued and guaranteed by the U.S. Treasury, Fannie Mae, Freddie Mac, Ginnie Mae and other agencies of the U.S. government are considered to be zero-loss securities. This determination is in consideration of the explicit and implicit guarantees by the US Government, the US Government’s ability to print its own currency, a history of no credit losses by the US Government and noted agencies and the current economic and financial condition of the United States and US Government providing no indication the zero-loss determination is unjustified . As of June 30, 2023 and December 31, 2022, the Company did not have any held-to-maturity debt securities past due. Accrued interest receivable on held-to-maturity debt securities totaled $17,764,000 and $17,524,000 at June 30, 2023 and December 31, 2022, respectively, and were excluded from the estimate of credit losses. Based on the Company’s evaluation, an insignificant amount of credit losses is expected on the held-to-maturity debt securities portfolio; therefore, no ACL was recorded at June 30, 2023 or December 31, 2022.

The Company had no significant purchases or sales of portfolio loans or reclassification of loans held for investment to loans held for sale during the six months ended June 30, 2023. Allowance for Credit Losses - Loans Receivable The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on loans.

The charge-offs in the other consumer loan segment is driven by deposit overdraft charge-offs which typically experience high charge-off rates and the amounts were comparable to historical trends. The other segments experience routine charge-offs and recoveries, with occasional large credit relationships charge-offs and recoveries that cause fluctuations from prior periods. During the six months ended June 30, 2023, there have been no significant changes to the types of collateral securing collateral-dependent loans.

Collateral-Dependent Loans A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. The collateral on the loans is a significant portion of what secures the collateral-dependent loans and significant changes to the fair value of the collateral can impact the ACL. During 2023, there were no significant changes to collateral which secures the collateral-dependent loans, whether due to general deterioration or other reasons.

Credit Quality Indicators The Company categorizes commercial real estate and other commercial loans into risk categories based on relevant information about the ability of borrowers to service their obligations. The following tables present the amortized cost in commercial real estate and other commercial loans based on the Company’s internal risk rating and the gross charge-offs. The date of a modification, renewal or extension of a loan is considered for the year of origination if the terms of the loan are as favorable to the Company as the terms are for a comparable loan to other borrowers with similar credit risk.

Variable Interest Entities

Equity Method Investments and Joint Ventures [Abstract]
Variable Interest Entities	Variable Interest Entities A VIE is a partnership, limited liability company, trust or other legal entity that meets one of the following criteria: 1) the entity’s equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support from other parties; 2) the holders of the equity investment at risk, as a group, lack the characteristics of a controlling financial interest; and 3) the voting rights of some holders of the equity investment at risk are disproportionate to their obligation to absorb losses or receive returns, and substantially all of the activities are conducted on behalf of the holder of equity investment at risk with disproportionately few voting rights. A VIE must be consolidated by the Company if it is deemed to be the primary beneficiary, which is the party involved with the VIE that has both: 1) the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance; and 2) the obligation to absorb the losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company’s VIEs are regularly monitored to determine if any reconsideration events have occurred that could cause the primary beneficiary status to change. A previously unconsolidated VIE is consolidated when the Company becomes the primary beneficiary. A previously consolidated VIE is deconsolidated when the Company ceases to be the primary beneficiary or the entity is no longer a VIE. Consolidated Variable Interest Entities The Company has equity investments in Certified Development Entities (“CDE”) which have received allocations of New Markets Tax Credits (“NMTC”). The NMTC program provides federal tax incentives to investors to make investments in distressed communities and promotes economic improvements through the development of successful businesses in these communities. The NMTC is available to investors over seven years and is subject to recapture if certain events occur during such period. The maximum exposure to loss in the CDEs is the amount of equity invested and credit extended by the Company. However, the Company has credit protection in the form of indemnification agreements, guarantees, and collateral arrangements. The Company has evaluated the variable interests held by the Company in each CDE (NMTC) investment and determined the Company does not individually meet the characteristics of a primary beneficiary; however, the related-party group does meet the criteria as a group and substantially all of the activities of the CDEs either involve or are conducted on behalf of the Company. As a result, the Company is the primary beneficiary of the CDEs and their assets, liabilities, and results of operations are included in the Company’s consolidated financial statements. The primary activities of the CDEs are recognized in commercial loans interest income and other borrowed funds interest expense on the Company’s statements of operations and the federal income tax credit allocations from the investments are recognized in the Company’s statements of operations as a component of income tax expense. Such related cash flows are recognized in loans originated, principal collected on loans and change in other borrowed funds. The Bank is also the sole member of certain tax credit funds that make direct investments in qualified affordable housing projects (e.g., Low-Income Housing Tax Credit [“LIHTC”] partnerships). As such, the Company is the primary beneficiary of these tax credit funds and their assets, liabilities, and results of operations are included in the Company’s consolidated financial statements. The following table summarizes the carrying amounts of the consolidated VIEs’ assets and liabilities included in the Company’s statements of financial condition and are adjusted for intercompany eliminations. All assets presented can be used only to settle obligations of the consolidated VIEs and all liabilities presented consist of liabilities for which creditors and other beneficial interest holders therein have no recourse to the general credit of the Company.

The LIHTCs are indirect federal subsidies to finance low-income housing and are used in connection with both newly constructed and renovated residential rental buildings. Once a project is placed in service, it is generally eligible for the tax credit for ten years. To continue generating the tax credit and to avoid tax credit recapture, a LIHTC building must satisfy specific low-income housing compliance rules for a full fifteen years. The maximum exposure to loss in the VIEs is the amount of equity invested and credit extended by the Company. However, the Company has credit protection in the form of indemnification agreements, guarantees, and collateral arrangements. The Company has evaluated the variable interests held by the Company in each LIHTC investment and determined that the Company does not have controlling financial interests in such investments, and is not the primary beneficiary. The Company reports the investments in the unconsolidated LIHTCs as other assets on the Company’s statements of financial condition. There were no impairment losses on the Company’s LIHTC investments during the six months ended June 30, 2023 and 2022. Future unfunded contingent equity commitments related to the Company’s LIHTC investments at June 30, 2023 are as follows: (Dollars in thousands) Amount Years ending December 31, 2023 $ 18,954 2024 54,103 2025 29,095 2026 10,013 2027 351 Thereafter 2,451 Total $ 114,967 The Company has elected to use the proportional amortization method, and more specifically the practical expedient method, for the amortization of all eligible LIHTC investments and amortization expense is recognized as a component of income tax expense.

The trust subsidiaries have no assets, operations, revenues or cash flows other than those related to the issuance, administration and repayment of the securities held by third parties. The trust subsidiaries are not included in the Company’s consolidated financial statements because the sole asset of each trust subsidiary is a receivable from the Company, even though the Company owns all of the voting equity shares of the trust subsidiaries, has fully guaranteed the obligations of the trust subsidiaries and may have the right to redeem the third party securities under certain circumstances. The Company reports the trust preferred securities issued to the trust subsidiaries as subordinated debentures on the Company’s statements of financial condition.

Fair Value of Assets and Liabil

Fair Value of Assets and Liabilities	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	Fair Value of Assets and Liabilities Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. There is a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are as follows: Level 1 Quoted prices in active markets for identical assets or liabilities Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities Transfers in and out of Level 1 (quoted prices in active markets), Level 2 (significant other observable inputs) and Level 3 (significant unobservable inputs) are recognized on the actual transfer date. There were no transfers between fair value hierarchy levels during the six month periods ended June 30, 2023 and 2022. Recurring Measurements The following is a description of the inputs and valuation methodologies used for assets and liabilities measured at fair value on a recurring basis, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy. There have been no significant changes in the valuation techniques during the period ended June 30, 2023. Debt securities, available-for-sal e. The fair value for available-for-sale debt securities is estimated by obtaining quoted market prices for identical assets, where available. If such prices are not available, fair value is based on independent asset pricing services and models, the inputs of which are market-based or independently sourced market parameters, including but not limited to, yield curves, interest rates, volatilities, market spreads, prepayments, defaults, recoveries, cumulative loss projections, and cash flows. Such securities are classified in Level 2 of the valuation hierarchy. Where Level 1 or Level 2 inputs are not available, such securities are classified as Level 3 within the hierarchy. Fair value determinations of available-for-sale debt securities are the responsibility of the Company’s corporate accounting and treasury departments. The Company obtains fair value estimates from independent third party vendors on a monthly basis. The vendors’ pricing system methodologies, procedures and system controls are reviewed to ensure they are appropriately designed and operating effectively. The Company reviews the vendors’ inputs for fair value estimates and the recommended assignments of levels within the fair value hierarchy. The review includes the extent to which markets for debt securities are determined to have limited or no activity, or are judged to be active markets. The Company reviews the extent to which observable and unobservable inputs are used as well as the appropriateness of the underlying assumptions about risk that a market participant would use in active markets, with adjustments for limited or inactive markets. In considering the inputs to the fair value estimates, the Company places less reliance on quotes that are judged to not reflect orderly transactions, or are non-binding indications. In assessing credit risk, the Company reviews payment performance, collateral adequacy, third party research and analyses, credit rating histories and issuers’ financial statements. For those markets determined to be inactive or limited, the valuation techniques used are models for which management has verified that discount rates are appropriately adjusted to reflect illiquidity and credit risk. Loans held for sale, at fair value. Loans held for sale measured at fair value, for which an active secondary market and readily available market prices exist, are initially valued at the transaction price and are subsequently valued by using quoted prices for similar assets, adjusted for specific attributes of that loan or other observable market data, such as outstanding commitments from third party investors. Loans held for sale measured at fair value are classified within Level 2. Included in gain on sale of loans were net gains of $335,000 and net losses of $1,388,000 for the six month periods ended June 30, 2023 and 2022, respectively, from the changes in fair value of loans held for sale measured at fair value. Electing to measure loans held for sale at fair value reduces certain timing differences and better matches changes in fair value of these assets with changes in the value of the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting. Loan interest rate lock commitments. F air value estimates for loan interest rate lock commitments were based upon the estimated sales price, origination fees, direct costs, interest rate changes, etc. and were obtained from an independent third party. The components of the valuation were observable or could be corroborated by observable market data and, therefore, were classified within Level 2 of the valuation hierarchy. Forward commitments to sell TBA securities. Fo rward commitments to sell TBA securities are used to economically hedge the interest rate risk associated with certain loan commitments. The fair value estimates for the TBA commitments were based upon the estimated sale of the TBA hedge obtained from an independent third party. The components of the valuation were observable or could be corroborated by observable market data and, therefore, were classified within Level 2 of the valuation hierarchy. Interest rate cap derivative financial instrum ents. F air value estimates for interest rate cap derivative financial instruments were based upon the discounted cash flows of known payments plus the option value of each caplet which incorporates market rate forecasts and implied market volatilities. The components of the valuation were observable or could be corroborated by observable market data and, therefore, were classified within Level 2 of the valuation hierarchy. The Company also obtained and compared the reasonableness of the pricing from independent third party valuations.

There have been no significant changes in the valuation techniques during the period ended June 30, 2023. Other real estate owned. OREO is initially recorded at fair value less estimated cost to sell, establishing a new cost basis. OREO is subsequently accounted for at lower of cost or fair value less estimated cost to sell. Estimated fair value of OREO is based on appraisals or evaluations (new or updated). OREO is classified within Level 3 of the fair value hierarchy. Collateral-dependent loans, net of ACL. Fair value estimates of collateral-dependent loans that are individually reviewed are based on the fair value of the collateral, less estimated cost to sell. Collateral-dependent individually reviewed loans are classified within Level 3 of the fair value hierarchy. The Company’s credit department reviews appraisals for OREO and collateral-dependent loans, giving consideration to the highest and best use of the collateral. The appraisal or evaluation (new or updated) is considered the starting point for determining fair value. The valuation techniques used in preparing appraisals or evaluations (new or updated) include the cost approach, income approach, sales comparison approach, or a combination of the preceding valuation techniques. The key inputs used to determine the fair value of the collateral-dependent loans and OREO include selling costs, discounted cash flow rate or capitalization rate, and adjustment to comparables. Valuations and significant inputs obtained by independent sources are reviewed by the Company for accuracy and reasonableness. The Company also considers other factors and events in the environment that may affect the fair value. The appraisals or evaluations (new or updated) are reviewed at least quarterly and more frequently based on current market conditions, including deterioration in a borrower’s financial condition and when property values may be subject to significant volatility. After review and acceptance of the collateral appraisal or evaluation (new or updated), adjustments to the impaired loan or OREO may occur. The Company generally obtains appraisals or evaluations (new or updated) annually. The following tables disclose the fair value measurement of assets with a recorded change during the period resulting from re-measuring the assets at fair value on a non-recurring basis: Fair Value Measurements (Dollars in thousands) Fair Value June 30, 2023 Quoted Prices Significant Significant Collateral-dependent impaired loans, net of ACL $ 1,377 — — 1,377 Total assets measured at fair value on a non-recurring basis $ 1,377 — — 1,377 Fair Value Measurements (Dollars in thousands) Fair Value December 31, 2022 Quoted Prices Significant Significant Collateral-dependent impaired loans, net of ACL $ 1,360 — — 1,360 Total assets measured at fair value on a non-recurring basis $ 1,360 — — 1,360 Non-recurring Measurements Using Significant Unobservable Inputs (Level 3) The following tables present additional quantitative information about assets measured at fair value on a non-recurring basis and for which the Company has utilized Level 3 inputs to determine fair value: Fair Value June 30, 2023 Quantitative Information about Level 3 Fair Value Measurements (Dollars in thousands) Valuation Technique Unobservable Input Range (Weighted-Average) 1 Collateral-dependent impaired loans, net of ACL $ 1,364 Cost approach Selling costs 10.0% - 10.0% (10.0%) 13 Sales comparison approach Selling costs 10.0% - 10.0% (10.0%) $ 1,377 Fair Value December 31, 2022 Quantitative Information about Level 3 Fair Value Measurements (Dollars in thousands) Valuation Technique Unobservable Input Range (Weighted-Average) 1 Collateral-dependent impaired loans, net of ACL $ 1,329 Cost approach Selling costs 10.0% - 10.0% (10.0%) 31 Sales comparison approach Selling Costs 10.0% - 10.0% (10.0%) $ 1,360 ______________________________ 1 The range for selling cost inputs represents reductions to the fair value of the assets. Fair Value of Financial Instruments The following tables present the carrying amounts, estimated fair values and the level within the fair value hierarchy of the Company’s financial instruments not carried at fair value. Receivables and payables due in one year or less, equity securities without readily determinable fair values and deposits with no defined or contractual maturities are excluded. There have been no significant changes in the valuation techniques during the period ended June 30, 2023. Cash and cash equivalents : fair value is estimated at book value. Debt securities, held-to-maturity : fair value for held-to-maturity debt securities is estimated in the same manner as available-for sale debt securities, which is described above. Loans receivable, net of ACL : The loans were fair valued on an individual basis, with consideration given to the loans' underlying characteristics, including account types, remaining terms and balance, interest rates, past delinquencies, current market rates, etc. The model utilizes a discounted cash flow approach to estimate the fair value of the loans using various assumptions such as prepayment speeds, projected default probabilities, losses given defaults, etc. The discounted cash flow approach models the credit losses directly in the projected cash flows. The model applies various assumptions regarding credit, interest, and prepayment risks for the loans based on loan types, payment types and fixed or variable classifications. Term Deposits : fair value of term deposits is estimated by discounting the future cash flows using rates of similar deposits with similar maturities. The market rates used were obtained from an independent third party based on current rates offered by the Company’s regional competitors. FHLB advances: fair value of advances is estimated based on borrowing rates currently available to the Company for advances with similar terms and maturities. FRB borrowing: fair value of borrowings through the FRB is estimated based on borrowing rates currently available to the Company through the FRB Bank Term Funding facility with similar terms and maturities. Repurchase agreements and other borrowed funds : fair value of term repurchase agreements and other term borrowings is estimated based on current repurchase rates and borrowing rates currently available to the Company for repurchases and borrowings with similar terms and maturities. The estimated fair value for overnight repurchase agreements and other borrowings is book value. Subordinated debentures : fair value of the subordinated debt is estimated by discounting the estimated future cash flows using current estimated market rates obtained from an independent third party. Off-balance sheet financial instrument s: unused lines of credit and letters of credit represent the principal categories of off-balance sheet financial instruments. The fair value of commitments is based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The fair value of unused lines of credit and letters of credit is not material; therefore, such commitments are not included in the following tables.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General Glacier Bancorp, Inc. (“Company”) is a Montana corporation headquartered in Kalispell, Montana. The Company provides a full range of banking services to individuals and businesses in Montana, Idaho, Utah, Washington, Wyoming, Colorado, Arizona and Nevada through its wholly-owned bank subsidiary, Glacier Bank (“Bank”). The Company offers a wide range of banking products and services, including: 1) retail banking; 2) business banking; 3) real estate, commercial, agriculture and consumer loans; and 4) mortgage origination and loan servicing. The Company serves individuals, small to medium-sized businesses, community organizations and public entities. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary for a fair presentation of the results for the interim periods. All such adjustments are of a normal recurring nature. These interim financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements and they should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. Operating results for the six months ended June 30, 2023 are not necessarily indicative of the results anticipated for the year ending December 31, 2023. The condensed consolidated statement of financial condition of the Company as of December 31, 2022 has been derived from the audited consolidated statements of the Company as of that date. The Company is a defendant in legal proceedings arising in the normal course of business. In the opinion of management, the disposition of pending litigation will not have a material affect on the Company’s consolidated financial position, results of operations or liquidity.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements of the Company include the parent holding company and the Bank, which consists of seventeen bank divisions and a corporate division. The corporate division includes the Bank’s investment portfolio, wholesale borrowings and other centralized functions. The Bank divisions operate under separate names, management teams and advisory directors. The Company considers the Bank to be its sole operating segment as the Bank 1) engages in similar bank business activity from which it earns revenues and incurs expenses; 2) the operating results of the Bank are regularly reviewed by the Chief Executive Officer (“CEO”) (i.e., the chief operating decision maker) who makes decisions about resources to be allocated to the Bank; and 3) financial information is available for the Bank. All significant inter-company transactions have been eliminated in consolidation. The Bank has subsidiary interests in variable interest entities (“VIE”) for which the Bank has both the power to direct the VIE’s significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could potentially be significant to the VIE. These subsidiary interests are included in the Company’s consolidated financial statements. The Bank also has subsidiary interests in VIEs for which the Bank does not have a controlling financial interest and is not the primary beneficiary. These subsidiary interests are not included in the Company’s consolidated financial statements. For additional information on the Bank’s interest in VIEs, see Note 7. The parent holding company owns non-bank subsidiaries that have issued trust preferred securities. The trust subsidiaries are not included in the Company’s consolidated financial statements. The Company's investments in the trust subsidiaries are included in other assets on the Company's statements of financial condition.
Cash and Cash Equivalents	Cash and Cash EquivalentsCash and cash equivalents include cash on hand, cash held as demand deposits at various banks and the Federal Reserve Bank (“FRB”), interest bearing deposits, federal funds sold, and liquid investments with original maturities of three months or less. The Bank is required to maintain an average reserve balance with either the FRB or in the form of cash on hand.
Debt Securities and Allowance for Credit Losses - Available-for-Sale Debt Securities	De bt Securities Debt securities for which the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity and are carried at amortized cost. Debt securities held primarily for the purpose of selling in the near term are classified as trading securities and are reported at fair value, with unrealized gains and losses included in income. Debt securities not classified as held-to-maturity or trading are classified as available-for-sale and are reported at fair value with unrealized gains and losses, net of income taxes, as a separate component of other comprehensive income (“OCI”). Premiums and discounts on debt securities are amortized or accreted into income using a method that approximates the interest method. The objective of the interest method is to calculate periodic interest income at a constant effective yield. The Company does not have any debt securities classified as trading securities. When the Company acquires another entity, it records the debt securities at fair value. The Company reviews and analyzes the various risks that may be present within the investment portfolio on an ongoing basis, including market risk, credit risk and liquidity risk. Market risk is the risk to an entity’s financial condition resulting from adverse changes in the value of its holdings arising from movements in interest rates, foreign exchange rates, equity prices or commodity prices. The Company assesses the market risk of individual debt securities as well as the investment portfolio as a whole. Credit risk, broadly defined, is the risk that an issuer or counterparty will fail to perform on an obligation. The credit rating of a security is considered the primary credit quality indicator for debt securities. Liquidity risk refers to the risk that a security will not have an active and efficient market in which the security can be sold. A debt security is investment grade if the issuer has adequate capacity to meet its commitment over the expected life of the investment, i.e., the risk of default is low and full and timely repayment of interest and principal is expected. To determine investment grade status for debt securities, the Company conducts due diligence of the creditworthiness of the issuer or counterparty prior to acquisition and ongoing thereafter consistent with the risk characteristics of the security and the overall risk of the investment portfolio. Credit quality due diligence takes into account the extent to which a security is guaranteed by the U.S. government and other agencies of the U.S. government. The depth of the due diligence is based on the complexity of the structure, the size of the security, and takes into account material positions and specific groups of securities or stratification for analysis and review of similar risk positions. The due diligence includes consideration of payment performance, collateral adequacy, internal analyses, third party research and analytics, external credit ratings and default statistics. The Company has acquired debt securities through acquisitions and if the securities have more than insignificant credit deterioration since origination, they are designated as purchased credit-deteriorated (“PCD”) securities. An ACL is determined using the same methodology as with other debt securities. The sum of a PCD security’s fair value and associated ACL becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the debt security is a noncredit discount or premium, which is amortized into interest income over the life of the security. Subsequent changes to the ACL are recorded through provision for credit losses. For additional information relating to debt securities, see Note 2. Allowance for Credit Losses - Available-for-Sale Debt Securities For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more-likely-than-not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through other expense. For the available-for-sale securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from cred it losses or other factors. In such assessment, the Company considers the extent to which fair value is less than amortized cost, if there are any changes to the investment grade of the security by a rating agency, and if there are any adverse conditions that impact the security. If this assessment indicates a credit loss exists, the present value of the cash flows expected to be collected from the security is compared to the amortized cost basis of the s ecurity. If the present value of the cash flows expected to be collected is less than the amortized cost basis, a potential credit loss exists and an ACL is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost. Any estimated credit losses that have not been recorded through an ACL are recognized in OCI. The Company has elected to exclude accrued interest from the estimate of credit losses for available-for-sale debt securities. As part of its non-accrual policy, the Company charges-off uncollectable interest at the time it is determined to be uncollectable. Allowance for Credit Losses - Held-to-Maturity Debt Securities For estimating the allowance for held-to-maturity (“HTM”) debt securities that share similar risk characteristics with other securities, such securities are pooled based on major security type. For pools of such securities with similar risk characteristics, the historical lifetime probability of default and severity of loss in the event of default is derived or obtained from external sources and adjusted for the expected effects of reasonable and supportable forecasts over the expected lives of the securities on those historical credit losses. Expected credit losses on securities in the held-to-maturity portfolio that do not share similar risk characteristics with any of the pools of debt securities are individually measured based on net realizable value, or the difference between the discounted value of the expected future cash flows, based on the original effective interest rate, and the recorded amortized cost basis of the securities.
Loans Held for Sale	Loans Held for Sale Loans held for sale generally consist of long-term, fixed rate, conforming, single-family residential real estate loans intended to be sold on the secondary market. Loans held for sale are recorded at fair value and may or may not be sold with servicing rights released. Changes in fair value are recognized in non-interest income. Fair value elections are made at the time of origination based on the Company’s fair value election policy.
Loans Receivable and Allowance for Credit Losses, and Loan Servicing Rights	Loans Receivable The Company’s loan segments or classes are based on the purpose of the loan and consist of residential real estate, commercial real estate, other commercial, home equity, and other consumer loans. Loans that are intended at origination to be held-to-maturity are reported at the unpaid principal balance less net c harge-offs and adjusted for deferred fees and costs on originated loans and unamortized premiums or discounts on acquired loans. Interest income is accrued on the unpaid principal balance. Fees and costs on originated loans and premiums or discounts on acquired loans are deferred and subsequently amortized or accreted as a yield adjustment over the expected life of the loan utilizing the interest or straight-line methods. The interest method is utilized for loans with scheduled payment terms and the objective is to calculate periodic interest income at a constant effective yield. The straight-line method is utilized for revolving lines of credit or loans with no scheduled payment terms. When a loan is paid off prior to maturity, the remaining unamortized fees and costs on originated loans and unamortized premiums or discounts on acquired loans are immediately recognized as interest income. Loans that are 30 days or more past due based on payments received and applied to the loan are considered delinquent. Loans are designated non-accrual and the accrual of interest is discontinued when the collection of the contractual principal or interest is unlikely. A loan is typically placed on non-accrual when principal or interest is due and has remained unpaid for 90 days or more. When a loan is placed on non-accrual status, interest previously accrued but not collected is reversed against current period interest income. Subsequent payments on non-accrual loans are applied to the outstanding principal balance if doubt remains as to the ultimate collectability of the loan. Interest accruals are not resumed on partially charged-off impaired loans. For other loans on non-accrual, interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to both principal and interest. Allowance for Credit Losses - Loans Receivable The ACL for loans receivable represents management’s estimate of credit losses over the expected contractual life of the loan portfolio. The estimate is determined based on the amortized cost of the loan portfolio including the loan balance adjusted for charge-offs, recoveries, deferred fees and costs, and loan discount and premiums. Recoveries are included only to the extent that such amounts were previously charged-off. The Company has elected to exclude accrued interest from the estimate of credit losses for loans. Determining the adequacy of the allowance is complex and requires a high degree of judgment by management about the effect of matters that are inherently uncertain. Subsequent evaluations of the then-existing loan portfolio, in light of the factors then prevailing, may result in significant changes in the allowance in those future periods. The allowance is increased for estimated credit losses which are recorded as expense. The portion of loans and overdraft balances determined by management to be uncollectable are charged-off as a reduction to the allowance and recoveries of amounts previously charged-off increase the allowance. The Company’s charge-off policy is consistent with bank regulatory standards. Consumer loans generally are charged-off when the loan becomes over 120 days delinquent. Real estate acquired as a result of foreclosure or by deed-in-lieu of foreclosure is classified as other real estate owned (“OREO”) until such time as it is sold. The expected credit loss estimate process involves procedures to consider the unique characteristics of each of the Company’s loan portfolio segments, which consist of residential real estate, commercial real estate, other commercial, home equity, and other consumer loans. When computing the allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, credit and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. The Company has determined a four consecutive quarter forecasting period is a reasonable and supportable period. Expected credit loss for periods beyond reasonable and supportable forecast periods are determined based on a reversion method which reverts back to historical loss estimates over a four consecutive quarter period on a straight-line basis. Credit quality is assessed and monitored by evaluating various attributes and the results of those evaluations are utilized in underwriting new loans and the process for estimating the expected credit losses. The following paragraphs describe the risk characteristics relevant to each portfolio segment. Residential Real Estate. Residential real estate loans are secured by owner-occupied 1-4 family residences. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans is impacted by economic conditions within the Company’s market areas that affect the value of the residential property securing the loans and affect the borrowers' personal incomes. Mitigating risk factors for this loan segment include a large number of borrowers, geographic dispersion of market areas and the loans are originated for relatively smaller amounts. Commercial Real Estate . Commercial real estate loans typically involve larger principal amounts, and repayment of these loans is generally dependent on the successful operation of the property securing the loan and/or the business conducted on the property securing the loan. Credit risk in these loans is impacted by the creditworthiness of a borrower, valuation of the property securing the loan and conditions within the local economies in the Company’s diverse geographic market areas. Commercial . Commercial loans consist of loans to commercial customers for use in financing working capital needs, equipment purchases and business expansions. The loans in this category are repaid primarily from the cash flow of a borrower’s principal business operation. Credit risk in these loans is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations across the Company’s diverse geographic market areas. Home Equity . Home equity loans consist of junior lien mortgages and first and junior lien lines of credit (revolving open-end and amortizing closed-end) secured by owner-occupied 1-4 family residences. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans is impacted by economic conditions within the Company’s market areas that affect the value of the residential property securing the loans and affect the borrowers' personal incomes. Mitigating risk factors for this loan segment are a large number of borrowers, geographic dispersion of market areas and the loans are originated for terms that range from 10 to 15 years. Other Consumer . The other consumer loan portfolio consists of various short-term loans such as automobile loans and loans for other personal purposes. Repayment of these loans is primarily dependent on the personal income of the borrowers. Credit risk is driven by consumer economic factors (such as unemployment and general economic conditions in the Company’s diverse geographic market areas) and the creditworthiness of a borrower. The allowance is impacted by loan volumes, delinquency status, credit ratings, historical loss experiences, estimated prepayment speeds, weighted average lives and other conditions influencing loss expectations, such as reasonable and supportable forecasts of economic conditions. The methodology for estimating the amount of expected credit losses reported in the allowance has two basic components: 1) individual loans that do not share similar risk characteristics with other loans and the measurement of expected credit losses for such individual loans; and 2) the expected credit losses for pools of loans that share similar risk characteristics. Loans that do not Share Similar Risk Characteristics with Other Loans. For a loan that does not share similar risk characteristics with other loans, expected credit loss is measured based on the net realizable value, that is, the difference between the discounted value of the expected future cash flows, based on the original effective interest rate, and the amortized cost basis of the loan. For these loans, the expected credit loss is equal to the amount by which the net realizable value of the loan is less than the amortized cost basis of the loan (which is net of previous charge-offs and deferred loan fees and costs), except when the loan is collateral-dependent, that is, when foreclosure is probable or the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In these cases, expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. The Company has determined that non-accrual loans do not share similar risk characteristics with other loans and these loans are individually evaluated for estimated allowance for credit losses. The Company, through its credit monitoring process, may also identify other loans that do not share similar risk characteristics and individually evaluate such loans. The starting point for determining the fair value of collateral is to obtain external appraisals or evaluations (new or updated). The valuation techniques used in preparing appraisals or evaluations (new or updated) include the cost approach, income approach, sales comparison approach, or a combination of the preceding valuation techniques. The Company’s credit department reviews appraisals, giving consideration to the highest and best use of the collateral. The appraisals or evaluations (new or updated) are reviewed at least quarterly and more frequently based on current market conditions, including deterioration in a borrower’s financial condition and when property values may be subject to significant volatility. Adjustments may be made to the fair value of the collateral after review and acceptance of the collateral appraisal or evaluation (new or updated). Loans that Share Similar Risk Characteristics with other Loans. For estimating the allowance for loans that share similar risk characteristics with other loans, such loans are segregated into loan segments. Loans are designated into loan segments based on loans pooled by product types and similar risk characteristics or areas of risk concentration. In determining the ACL, the Company derives an estimated credit loss assumption from a model that categorizes loan pools based on loan type which is further segregated by the credit quality indicators. This model calculates an expected loss percentage for each loan segment by considering the non-discounted simple annual average historical loss rate of each loan segment (calculated through an “open pool” method), multiplying the loss rate by the amortized loan balance and incorporating that segment’s internally generated prepayment speed assumption and contractually scheduled remaining principal pay downs on a loan level basis. The annual historical loss rates are adjusted over a reasonable economic forecast period by a multiplier that is calculated based upon current national economic forecasts as a proportion of each segment’s historical average loss levels. The Company will then revert from the economic forecast period back to the historical average loss rate in a straight-line basis. After the reversion period, the loans will be assumed to experience their historical loss rate for the remainder of their contractual lives. The model applies the expected loss rate over the projected cash flows at the individual loan level and then aggregates the losses by loan segment in determining their quantitative allowance. The Company will also include qualitative adjustments to adjust the ACL on loan segments to the extent the current or future market conditions are believed to vary substantially from historical conditions in regards to: • lending policies and procedures; • i nternational, national, regional and local economic business conditions, developments, or environmental conditions that affect the collectability of the portfolio, including the condition of various markets; • the nature and volume of the loan portfolio including the terms of the loans; • the experience, ability, and depth of the lending management and other relevant staff; • the volume and severity of past due and adversely classified or graded loans and the volume of non-accrual loans; • the quality of our loan review system; • the value of underlying collateral for collateralized loans; • the existence and effect of any concentrations of credit, and changes in the level of concentrations; and • the effect of external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the existing portfolio. The Company regularly reviews loans in the portfolio to assess credit quality indicators and to determine the appropriate loan classification and grading in accordance with applicable bank regulations. The primary credit quality indicator for residential, home equity and other consumer loans is the days past due status, which consists of the following categories: 1) performing loans; 2) 30 to 89 days past due loans; and 3) non-accrual and 90 days or more past due loans. The primary credit quality indicator for commercial real estate and commercial loans is the Company’s internal risk rating system, which includes the following categories: 1) pass loans; 2) special mention loans; 3) substandard loans; and 4) doubtful or loss loans. Such credit quality indicators are regularly monitored and incorporated into the Company’s allowance estimate. The following paragraphs further define the internal risk ratings for commercial real estate and commercial loans. Pass Loans. These ratings represent loans that are of acceptable, good or excellent quality with very limited to no risk. Loans that do not have one of the following ratings are considered pass loans. Special Mention Loans. These ratings represent loans that are designated as special mention per the regulatory definition. Special mention loans are currently protected but are potentially weak. The credit risk may be relatively minor yet constitute an undue and unwarranted risk in light of the circumstances surrounding a specific loan. The rating may be used to identify credit with potential weaknesses that if not corrected may weaken the loan to the point of inadequately protecting the Bank’s credit position. Examples include a lack of supervision, inadequate loan agreement, condition, or control of collateral, incomplete, or improper documentation, deviations from lending policy, and adverse trends in operations or economic conditions. Substandard Loans. This rating represents loans that are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged. A loan so classified must have a well-defined weakness that jeopardizes the liquidation of the debt. These loans are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregated amount of substandard loans, does not have to exist in an individual loan classified substandard. Doubtful/Loss Loans. A loan classified as doubtful has the characteristics that make collection in full, on the basis of currently existing facts, conditions, and values, highly improbable. The possibility of loss is extremely high, but because of pending factors, which may work to the advantage and strengthening of the loan, its classification as loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral and refinancing plans. Loans are classified as loss when they are deemed to be not collectible and of such little value that continuance as an active asset of the Bank is not warranted. Loans classified as loss must be charged-off. Assignment of this classification does not mean that an asset has absolutely no recovery or salvage value, but that it is not practical or desirable to defer writing off a basically worthless asset, even though partial recovery may be attained in the future. Restructured Loans On January 1, 2023, the Company adopted FASB ASU 2022-02, Financial Instruments - Credit Losses, Troubled Debt Restructurings and Vintage Disclosures, which eliminated the accounting guidance for TDRs by creditors in Accounting Standard Codification (ASC) Subtopic 310-40, and enhanced the disclosure requirements for certain loan refinancing and restructures by creditors when a borrower is experiencing financial difficulty. The company identifies modifications to borrowers experiencing financial difficulty (“MBFD”) as a loan that has been modified for the borrower that is experiencing financial difficulties. The Company considers some of the indicators that a borrower is experiencing financial difficulty to be: currently in payment default on any of their debt, declaring bankruptcy, going concern, borrower’s securities have been delisted, and other indicators of inability to meet obligations. This list does not include all potential indicators of a borrower’s financial difficulties. The allowance for credit losses on a l oans that are considered MBFD’s are measured using the same method as all other loans held for investment. Prior to the adoption of this guidance, restructured loans were considered to be a troubled debt restructuring (“TDR”) if the creditor, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would have not otherwise considered. The allowance for credit losses on a TDR were measured using the same method as all other loans held for investment. Allowance for Credit Losses - Off-Balance Sheet Credit Exposures The Company maintains a separate allowance for credit losses for off-balance sheet credit exposures, including unfunded loan commitments. Such ACL is included in other liabilities on the Company’s statements of financial condition. The Company estimates the amount of expected losses by calculating a commitment usage factor over the contractual period for exposures and applying the loss factors used in the allowance for credit loss methodology to the results of the usage calculation to estimate the liability for credit losses related to unfunded commitments for each loan segment. No credit loss estimate is reported for off-balance sheet credit exposures that are unconditionally cancellable by the Bank or for unfunded amounts under such arrangements that may be drawn prior to the cancellation of the arrangement. Provision for Credit Losses Loan Servicing Rights For residential real estate loans that are sold with servicing retained, servicing rights are initially recorded at fair value in other assets and gain on sale of loans. Fair value is based on market prices for comparable mortgage servicing contracts. The servicing asset is subsequently measured using the amortization method which requires the servicing rights to be amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Loan servicing rights are evaluated for impairment based upon the fair value of the servicing rights compared to the carrying value. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the carrying value. If the Company later determines that all or a portion of the impairment no longer exists, a reduction in the valuation allowance may be recorded. Changes in the valuation allowance are recorded in other income. The fair value of the servicing assets are subject to significant fluctuations as a result of changes in estimated actual prepayment speeds and default rates and losses.
Premises and Equipment	Premises and EquipmentPremises and equipment are accounted for at cost less depreciation. Depreciation is computed on a straight-line method over the estimated useful lives or the term of the related lease. The estimated useful life for office buildings is 15 to 40 years and the estimated useful life for furniture, fixtures, and equipment is 3 to 10 years. Interest is capitalized for any significant building projects.
Lessee Leases	Leases The Company leases certain land, premises and equipment from third parties. A lessee lease is classified as an operating lease unless it meets certain criteria (e.g., lease contains option to purchase that Company is reasonably certain to exercise), in which case it is classified as a finance lease. Operating leases are included in net premises and equipment and other liabilities on the Company’s statements of financial condition and lease expense for lease payments is recognized on a straight-line basis over the lease term. Finance leases are included in net premises and equipment and other borrowed funds on the Company’s statements of financial condition. Right-of-use (“ROU”) assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. An ROU asset represents the right to use the underlying asset for the lease term and also includes any direct costs and payments made prior to lease commencement and excludes lease
Lessor Leases	The Company also leases certain premises and equipment to third parties. A lessor lease is classified as an operating lease unless it meets certain criteria that would classify it as either a sales-type lease or a direct financing lease.
Other Real Estate Owned	Other Real Estate Owned Property acquired by foreclosure or deed-in-lieu of foreclosure is initially recorded at fair value, less estimated selling cost, at acquisition date (i.e., cost of the property). The Company is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan upon the occurrence of either the Company obtaining legal title to the property or the borrower conveying all interest in the property through a deed-in-lieu or similar agreement. Fair value is determined as the amount that could be reasonably expected in a current sale between a willing buyer and a willing seller in an orderly transaction between market participants at the measurement date. Subsequent to the initial acquisition, if the fair value of the asset, less estimated selling cost, is less than the cost of the property, a loss is recognized in other expense and the asset carrying value is reduced. Gain or loss on disposition of OREO is recorded in non-interest income or non-interest expense, respectively. In determining the fair value of the properties on the date of transfer and any subsequent estimated losses of net realizable value, the fair value of other real estate acquired by foreclosure or deed-in-lieu of foreclosure is determined primarily based upon appraisal or evaluation of the underlying property value.
Business Combination and Intangible Assets	Business Combinations and Intangible Assets Acquisition accounting requires the total purchase price to be allocated to the estimated fair values of assets acquired and liabilities assumed, including certain intangible assets. Goodwill is recorded if the purchase price exceeds the net fair value of assets acquired and a bargain purchase gain is recorded in other income if the net fair value of assets acquired exceeds the purchase price. Adjustment of the allocated purchase price may be related to fair value estimates for which all information has not been obtained of the acquired entity known or discovered during the allocation period, the period of time required to identify and measure the fair values of the assets and liabilities acquired in the business combination. The allocation period is generally limited to one year following consummation of a business combination. Core deposit intangible represents the intangible value of depositor relationships resulting from deposit liabilities assumed in acquisitions and is amortized using an accelerated method based on an estimated runoff of the related deposits. The core deposit intangible is evaluated for impairment and recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable, with any changes in estimated useful life accounted for prospectively over the revised remaining life. The Company tests goodwill for impairment at the reporting unit level annually during the third quarter. The Company has identified that each of the Bank divisions are reporting units (i.e., components of the Glacier Bank operating segment) given that each division has a separate management team that regularly reviews its respective division financial information; however, the reporting units are aggregated into a single reporting unit due to the reporting units having similar economic characteristics. The goodwill of a reporting unit is tested for impairment between annual tests if an event occurs or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying amount. Examples of events and circumstances that could trigger the need for interim impairment testing include: • a significant change in legal factors or in the business climate; • an adverse action or assessment by a regulator; • unanticipated competition; • a loss of key personnel; • a more-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or otherwise disposed of; and • the testing for recoverability of a significant asset group within a reporting unit.
Equity Securities	Equity Securities Non-marketable equity securities primarily consist of Federal Home Loan Bank (“FHLB”) stock. FHLB stock is restricted because such stock may only be sold to FHLB at its par value. Due to restrictive terms, and the lack of a readily determinable fair value, FHLB stock is carried at cost and evaluated for impairment. The investments in FHLB stock are required investments related to the Company’s borrowings from FHLB. FHLB obtains its funding primarily through issuance of consolidated obligations of the FHLB system. The U.S. government does not guarantee these obligations, and each of the regional FHLBs is jointly and severally liable for repayment of each other’s debt.
Federal Reserve Bank Term Funding Program	Federal Reserve Bank Term Funding ProgramDuring the first quarter of 2023, the FRB offered a new Bank Term Funding Program (“BTFP”) for eligible depository institutions. The BTFP offers loans of up to one year in length to institutions pledging collateral eligible for purchase by the FRB in open market operations such as U.S. Treasuries, U.S. Agency securities, and U.S. agency mortgage-backed securities. These assets will be valued at par for pledging purposes.
Other Borrowings	Other BorrowingsBorrowings of the Company’s consolidated variable interest entities and finance lease arrangements are included in other borrowings.
Bank-Owned Life Insurance	Bank-Owned Life InsuranceThe Company maintains bank-owned life insurance policies on certain current and former employees and directors, which are recorded at their cash surrender values as determined by the insurance carriers. The appreciation in the cash surrender value of the policies is recognized as a component of other non-interest income in the Company’s statements of operations.
Derivatives and Hedging Activities	Derivatives and Hedging Activities The Company is exposed to certain risks relating to its ongoing operations. The primary risk managed by using derivative instruments is interest risk. Interest rate caps and interest rate swaps have been entered into to manage interest rate risk associated with variable rate borrowings and were designated as cash flow hedges. The Company does not enter into derivative instruments for trading or speculative purposes.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when services or products are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled. The Company’s principal source of revenue is interest income from debt securities and loans. Revenue from contracts with customers within the scope of Accounting Standards Codification TM (“ASC”) Topic 606 was $43,200,000 and $39,174,000 for the six months ended June 30, 2023 and 2022, respectively, and largely consisted of revenue from service charges and other fees from deposits (e.g., overdraft fees, ATM fees, debit card fees). Due to the short-term nature of the Company’s contracts with customers, an insignificant amount of receivables related to such revenue was recorded at June 30, 2023 and December 31, 2022 and there were no impairment losses recognized. Policies specific to revenue from contracts with customers include the following: Service Charges. Revenue from service charges consists of service charges and fees on deposit accounts under depository agreements with customers to provide access to deposited funds and, when applicable, pay interest on deposits. Service charges on deposit accounts may be transactional or non-transactional in nature. Transactional service charges occur in the form of a service or penalty and are charged upon the occurrence of an event (e.g., overdraft fees, ATM fees, wire transfer fees). Transactional service charges are recognized as services are delivered to and consumed by the customer, or as penalty fees are charged. Non-transactional service charges are charges that are based on a broader service, such as account maintenance fees and dormancy fees, and are recognized on a monthly basis. Debit Card Fees. Revenue from debit card fees includes interchange fee income from debit cards processed through card association networks. Interchange fees represent a portion of a transaction amount that the Company and other involved parties retain to compensate themselves for giving the cardholder immediate access to funds. Interchange rates are generally set by the card association networks and are based on purchase volumes and other factors. The Company records interchange fees as services are provided.
Accounting Guidance Adopted and Pending Adoption	Accounting Guidance Adopted in 2023 The ASC is the Financial Accounting Standards Board (“FASB”) officially recognized source of authoritative GAAP applicable to all public and non-public non-governmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under the authority of the federal securities laws are also sources of authoritative GAAP for the Company as an SEC registrant. All other accounting literature is non-authoritative. The following provides a description of a recently adopted Accounting Standards Updates (“ASU”) that could have a material effect on the Company’s financial position or results of operations. ASU 2022-02 - Troubled Debt Restructurings and Vintage Disclosures. In March 2022, FASB amended Subtopic ASC 310-40 and Subtopic 326-20 relating to post-current expected credit losses (“CECL”) (ASU 2016-13) implementation areas including TDRs and vintage disclosures. The amendments in this Update eliminate the accounting guidance for TDRs by creditors in Subtopic 326-40, while enhancing disclosure requirements. The amendments to Subtopic 326-20 require an entity to disclose current-period gross write-offs by year of origination for financing receivables within the scope of Subtopic 326-20. For entities that have adopted CECL, the amendments are effective for public business entities the first interim and annual reporting periods beginning after December 15, 2022. Early adoption is permitted if an entity has adopted CECL and the entity may elect to adopt the amendments about TDRs and related disclosure enhancements separately from the amendments related to vintage disclosures. The Company adopted the amendments beginning January 1, 2023. The Company adjusted its processes and procedures related to the amendments and it did not have a material impact to the Company’s financial position and results of operations. ASU 2020-04, ASU 2021-01, ASU 2022-06 - Reference Rate Reform. In March 2020, FASB amended topic 848 related to the facilitation of the effects of reference rate reform on financial reporting. The amendment provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”). These updates are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2024. The Company has reviewed all of its LIBOR based products and all products have been adjusted to another index as LIBOR ceased to be published after June 30, 2023. The Company adjusted its processes and procedures related to the amendments and it did not have a material impact to the Company’s financial position and results and operations. Accounting Guidance Pending Adoption in 2023 The following provides a description of a recently issued but not yet effective ASU that could have a material effect on the Company’s financial position or results of operations
