Accounting Policies [Abstract]
Basis of Presentation	Significant Accounting Policies Basis of Presentation and Consolidation: The consolidated financial statements include the accounts of Isabella Bank Corporation, a financial services holding company, and its wholly owned subsidiary, Isabella Bank. All intercompany balances and accounts have been eliminated in consolidation. References to “the Corporation”, “Isabella”, “we”, “our”, “us”, and similar terms refer to the consolidated entity consisting of Isabella Bank Corporation and its subsidiary. References to Isabella Bank or “the Bank” refers to Isabella Bank Corporation’s subsidiary, Isabella Bank. The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, all adjustments considered necessary for a fair presentation have been included. Operating results for the three and nine-month periods ended September 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. For further information, refer to our Annual Report on Form 10-K for the year ended December 31, 2022. Use of Estimates: In preparing consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, we make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and reported amounts of revenues and expenses during the reporting year. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the ACL, the fair value of AFS investment securities, and the valuation of goodwill and other intangible assets. Accounting Changes and Reclassifications: Certain amounts reported in the interim 2022 consolidated financial statements have been reclassified to conform with the 2023 presentation. On January 1, 2023, we adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” as subsequently updated for certain clarifications, targeted relief and codification improvements. ASC 326 updated the measurement for credit losses for AFS debt securities and assets measured at amortized cost, which includes loans, trade receivables, and any other financial assets with the contractual right to receive cash and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses. Prior to ASU No. 2016-13, GAAP required an “incurred loss” methodology for recognizing credit losses that delayed recognition until it was probable a loss has been incurred. Under the incurred loss approach, entities were limited to a probable initial recognition threshold when credit losses were measured; an entity generally considered only past events and current conditions when measuring the incurred loss. We adopted ASC 326 using the modified retrospective method for all financial assets measured at amortized cost and off balance sheet credit exposures. Results for reporting periods beginning January 1, 2023 are presented under ASC 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP and the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2022. We recorded a net decrease to retained earnings of $2,417 as of January 1, 2023 for the cumulative effect of adopting ASC 326. We adopted ASC 326 using the prospective transition approach for AFS debt securities for which other-than-temporary impairment had been recognized prior to January 1, 2023. As a result, the amortized cost basis remains the same before and after the effective date of ASC 326. The effective interest rate on these debt securities was not changed. Amounts previously recognized in accumulated other comprehensive income as of January 1, 2023 relating to improvements in cash flows expected to be collected will be accreted into income over the remaining life of the asset. Recoveries of amounts previously written off relating to improvements in cash flows beginning January 1, 2023 will be recorded in earnings when received. The following table details the impact of the adoption of ASC 326: January 1, 2023 Pre-Adoption Impact of Post-Adoption Cumulative Loans: Commercial and industrial $ 860 $ (58) $ 802 $ 46 Commercial real estate 461 5,532 5,993 (4,370) Agricultural 577 (247) 330 195 Residential real estate 617 3,535 4,152 (2,793) Consumer 961 356 1,317 (281) Unallocated 6,374 (6,374) — 5,035 Total $ 9,850 $ 2,744 $ 12,594 $ (2,168) Off-balance-sheet credit exposures $ — $ 315 $ 315 $ (249) In connection with the adoption of ASC 326, we revised certain accounting policies and implemented certain accounting policy elections, which are provided below. All other accounting policies are materially the same as those discussed in Note 1 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2022. AFS Securities: Purchases of investment securities are generally classified as AFS. However, we may elect to classify securities as either held to maturity or trading. Securities classified as AFS debt securities are recorded at fair value, with unrealized gains and losses, net of the effect of deferred income taxes, excluded from earnings and reported in other comprehensive income (loss). Included in AFS securities are auction rate money market preferred securities. These investments, for federal income tax purposes, have no federal income tax impact given the nature of the investments. Auction rate money market preferred securities are recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss). Purchase premiums and discounts are recognized in interest income using the interest method over the term of the securities. Realized gains and losses on the sale of AFS securities are determined using the specific identification method. ACL - AFS Securities: AFS securities are reviewed quarterly for possible credit impairment. In determining whether a credit-related impairment exists for debt securities, we assess whether: (a) we do not have the intent to sell the security; and (b) it is more likely than not we will not have to sell the security before recovery of its cost basis. If either of these conditions are met, any previously recognized allowances are charged-off and the security's amortized cost is written down to fair value through income. If these conditions are not met, the security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In order to determine the amount of the credit loss for a debt security, we calculate the recovery value by performing a discounted cash flow analysis based on the current cash flows and future cash flows we expect to recover. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. The amount of the impairment related to other risk factors is recognized as a component of other comprehensive income. Adjustments to the allowance are reported in the income statement as a provision for credit losses. We made an accounting policy election to exclude accrued interest receivable on AFS securities from the estimate of credit losses. AFS securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management, or when criteria regarding intent or requirement to sell is met. Loans: Loans that we have the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balance adjusted for any charge-offs, the ACL, and any deferred fees or costs. Interest income on loans is accrued over the term of the loan based on the principal amount outstanding. Loan origination fees and certain direct loan origination costs are capitalized and recognized as a component of interest income over the term of the loan using the appropriate yield methods. The accrual of interest on agricultural, commercial and mortgage loans is discontinued at the time the loan is 90 days or more past due unless the credit is well secured and in the process of collection. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed in nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. For loans that are placed on nonaccrual status or charged-off, all interest accrued in the current calendar year, but not collected, is reversed against interest income while interest accrued in prior calendar years, but not collected is charged against the ACL. Interest income on loans in nonaccrual status is not recognized until qualifying for return to accrual status. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. For loans not classified as nonaccrual, interest income continues to be accrued over the term of the loan based on the principal amount outstanding. ACL - Loans: The ACL on loans is calculated in accordance with ASC 326 and is deducted from the amortized cost basis of loans to present our best estimate of the net amount expected to be collected. The ACL is established through a provision for credit losses charged to earnings. Loan losses are charged against the allowance when we believe the uncollectability of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. We made an accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses. We evaluate the ACL on a regular basis. Our periodic review of the collectability of loans considers historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, prevailing economic conditions, and reasonable and supportable forecasts. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The ACL consists of a general component and loans individually analyzed. The general component covers loans not specifically analyzed and is based on historical loss experience, current conditions, and reasonable and supportable forecasts. The general component also includes uncertainties that we believe could affect our estimate of probable losses based on qualitative factors. Loans in nonaccrual status are individually analyzed on a loan-by-loan basis. Loans evaluated individually are not included in the general, or pooled, component of the ACL. For collateralized loans, the loan's specific allowance is measured by the fair value of the collateral approach. The specific reserve is based on the fair value of the collateral, less costs to sell if foreclosure is probable, and an allowance is established when the collateral value is lower than the carrying value of the loan. When the discounted cash flow method is used to measure the loan's specific allowance, the effective interest rate is used to discount expected cash flows to incorporate expected prepayments. An allowance is established when the discounted cash flows are lower than the carrying value of the loan. For large groups of smaller-balance, homogeneous loans, we may collectively evaluate these loans for measurement of an allowance. Off Balance Sheet Credit Related Financial Instruments: In the ordinary course of business, we enter into commitments to extend credit, including commitments under credit card arrangements, commercial lines of credit, home equity lines of credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded only when funded. In connection with these commitments, we established an allowance for credit losses related to off-balance-sheet credit exposures. The allowance, recorded in a liability account, is calculated in accordance with ASC 326 and represents expected credit losses over the contractual period for which we are exposed to credit risk resulting from a contractual obligation to extend credit. The estimate of expected credit losses considers both the likelihood that funding will occur and the amount expected to be funded over the estimated remaining life of the commitment. The likelihood and expected amount of funding are based on historical utilization rates. No allowance is recognized if we have the unconditional right to cancel the obligation. The allowance is reported as a component of accrued interest payable and other liabilities in our consolidated balance sheets. Adjustments to the allowance are reported in our income statement as a component of provision for credit losses.

As the auction rate money market preferred investments have continual call dates, they are not reported by a specific maturity group. Because of their variable monthly payments, mortgage-backed securities and collateralized mortgage obligations are not reported by a specific maturity group. Approximately $148,000 of the amortized cost of the collateralized mortgage portfolio consist of agency commercial mortgage-backed securities with defined maturity dates of less than ten years.

This is based on our analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors related to our AFS securities and consideration of our historical credit loss experience and internal forecasts. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. Furthermore, management does not have the intent to sell any of the securities classified as AFS in the table above, and believes it is more likely than not that we will not have to sell any such securities before a recovery of cost. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their respective maturity date or repricing date, or if the market yields for such investments decline.

We grant commercial, agricultural, residential real estate, and consumer loans to customers situated primarily in Bay, Clare, Gratiot, Isabella, Mecosta, Midland, Montcalm, and Saginaw counties in mid-Michigan. The ability of the borrowers to honor their repayment obligations is often dependent upon the real estate, agricultural, manufacturing, retail, gaming, tourism, health care, higher education, and general economic conditions of this region. Substantially all of our consumer and residential real estate loans are secured by various items of property, while commercial loans are secured primarily by real estate, business assets, and personal guarantees. A portion of loans are unsecured. Loans that we have the intent and ability to hold in our portfolio are reported at their outstanding principal balance adjusted for any charge-offs, the ACL, and deferred fees or costs. Unless a loan has a nonaccrual status, interest income is accrued over the term of the loan based on the principal amount outstanding. Loan origination fees and certain direct loan origination costs are capitalized and recognized as a component of interest income over the term of the loan using the appropriate amortization method. Commercial and agricultural loans include loans for commercial real estate, commercial operating loans, advances to mortgage brokers, farmland and agricultural production, and loans to states and political subdivisions. Repayment of these loans is dependent upon the successful operation and management of a business. We minimize our risk by limiting the amount of direct credit exposure to any one borrower to $18,000. Borrowers with direct credit needs of more than $18,000 may be serviced through the use of loan participations with other commercial banks. Commercial and agricultural real estate loans commonly require loan-to-value limits of 80% or less. Depending upon the type of loan, past credit history, and current operating results, we may require the borrower to pledge accounts receivable, inventory, property, or equipment. Government agency guarantee may be required. Personal guarantees and/or life insurance beneficiary assignments are generally required from the owners of closely held corporations, partnerships, and sole proprietorships. In addition, we may require annual financial statements, prepare cash flow analyses, and review credit reports. We offer adjustable rate mortgages, construction loans, and fixed rate residential real estate loans which have amortization periods up to a maximum of 30 years. We consider the anticipated direction of interest rates, balance sheet duration, the sensitivity of our balance sheet to changes in interest rates, our liquidity needs, and overall loan demand to determine whether or not to sell fixed rate loans to Freddie Mac. Our lending policies generally limit the maximum loan-to-value ratio on residential real estate loans to 100% of the lower of the appraised value of the property or the purchase price. Private mortgage insurance is typically required on loans with loan-to-value ratios in excess of 80% unless the loan qualifies for government guarantees. Underwriting criteria for originated residential real estate loans generally include: • Evaluation of the borrower’s ability to make monthly payments. • Evaluation of the value of the property securing the loan. • Ensuring the payment of principal, interest, taxes, and hazard insurance generally does not exceed 28% of a borrower’s gross income. • Ensuring all debt servicing does not exceed 40% of income. • Verification of acceptable credit reports. • Verification of employment, income, and financial information. Appraisals are performed by independent appraisers and are reviewed for appropriateness. Generally, mortgage loan requests are reviewed by our mortgage loan committee or through a secondary market underwriting system; loans in excess of $1,000 require the approval of one or more of the following committees: Internal Loan Committee, the Executive Loan Committee, or the Board of Directors. Consumer loans include secured and unsecured personal loans. Loans are amortized for a period of up to 15 years based on the age and value of the underlying collateral. The underwriting emphasis is on a borrower’s perceived intent and ability to pay rather than collateral value. No consumer loans are sold to the secondary market. Nonaccrual and Past Due Loans The accrual of interest on commercial and agricultural loans, as well as residential real estate loans, is discontinued at the time a loan is 90 days or more past due unless the credit is well-secured and in the process of short-term collection. Upon transferring a loan to nonaccrual status, we perform an evaluation to determine the net realizable value of the underlying collateral. This evaluation is used to help determine if a charge-off is necessary. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on the contractual term of the loan. In all cases, a loan is placed in nonaccrual status at an earlier date if collection of principal or interest is considered doubtful. When a loan is placed in nonaccrual status, all interest accrued in the current calendar year, but not collected, is reversed against interest income while interest accrued in prior calendar years, but not collected, is charged against the ACL. Loans may be returned to accrual status after six months of continuous performance and achievement of current payment status.

$ 744,440 $ 73,002 $ 31,983 $ 104,985 $ 849,425 Internally assigned credit risk ratings are reviewed, at a minimum, when loans are renewed or when management has knowledge of improvements or deterioration of the credit quality of individual credits. Descriptions of the internally assigned credit risk ratings for commercial and agricultural loans are as follows: 1. EXCELLENT – Substantially Risk Free Credit has strong financial condition and solid earnings history, characterized by: • High liquidity, strong cash flow, low leverage. • Unquestioned ability to meet all obligations when due. • Experienced management, with management succession in place. • Secured by cash. 2. HIGH QUALITY – Limited Risk Credit with sound financial condition and a positive trend in earnings supplemented by: • Favorable liquidity and leverage ratios. • Ability to meet all obligations when due. • Management with successful track record. • Steady and satisfactory earnings history. • If loan is secured, collateral is of high quality and readily marketable. • Access to alternative financing. • Well defined primary and secondary source of repayment. • If supported by guaranty, the financial strength and liquidity of the guarantor(s) are clearly evident. 3. HIGH SATISFACTORY – Reasonable Risk Credit with satisfactory financial condition and further characterized by: • Working capital adequate to support operations. • Cash flow sufficient to pay debts as scheduled. • Management experience and depth appear favorable. • Loan performing according to terms. • If loan is secured, collateral is acceptable and loan is fully protected. 4. LOW SATISFACTORY – Acceptable Risk Credit with bankable risks, although some signs of weaknesses are shown: • Would include most start-up businesses. • Occasional instances of trade slowness or repayment delinquency – may have been 10-30 days slow within the past year. • Management’s abilities are apparent yet unproven. • Weakness in primary source of repayment with adequate secondary source of repayment. • Loan structure generally in accordance with policy. • If secured, loan collateral coverage is marginal. To be classified as less than satisfactory, only one of the following criteria must be met. 5. SPECIAL MENTION – Criticized Credit constitutes an undue and unwarranted credit risk but not to the point of justifying a classification of substandard. The credit risk may be relatively minor yet constitutes an unwarranted risk in light of the circumstances surrounding a specific loan: • Downward trend in sales, profit levels, and margins. • Impaired working capital position. • Cash flow is strained in order to meet debt repayment. • Loan delinquency (30-60 days) and overdrafts may occur. • Shrinking equity cushion. • Diminishing primary source of repayment and questionable secondary source. • Management abilities are questionable. • Weak industry conditions. • Litigation pending against the borrower. • Loan may need to be restructured to improve collateral position or reduce payments. • Collateral or guaranty offers limited protection. • Negative debt service coverage, however the credit is well collateralized and payments are current. 6. SUBSTANDARD – Classified Credit is inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged. There is a distinct possibility we will implement collection procedures if the loan deficiencies are not corrected. Any commercial loan placed in nonaccrual status will be rated “7” or worse. In addition, the following characteristics may apply: • Sustained losses have severely eroded the equity and cash flow. • Deteriorating liquidity. • Serious management problems or internal fraud. • Original repayment terms liberalized. • Likelihood of bankruptcy. • Inability to access other funding sources. • Reliance on secondary source of repayment. • Litigation filed against borrower. • Interest non-accrual may be warranted. • Collateral provides little or no value. • Requires excessive attention of the loan officer. • Borrower is uncooperative with loan officer. 7. VULNERABLE – Classified Credit is considered “Substandard” and warrants placing in nonaccrual status. Risk of loss is being evaluated and exit strategy options are under review. Other characteristics that may apply: • Insufficient cash flow to service debt. • Minimal or no payments being received. • Limited options available to avoid the collection process. • Transition status, expect action will take place to collect loan without immediate progress being made. 8. DOUBTFUL – Workout Credit has all the weaknesses inherent in a “Substandard” loan with the added characteristic that collection and/or liquidation is pending. The possibility of a loss is extremely high, but its classification as a loss is deferred until liquidation procedures are completed, or reasonably estimable. Other characteristics that may apply: • Normal operations are severely diminished or have ceased. • Seriously impaired cash flow. • Original repayment terms materially altered. • Secondary source of repayment is inadequate. • Survivability as a “going concern” is impossible. • Collection process has begun. • Bankruptcy petition has been filed. • Judgments have been filed. • Portion of the loan balance has been charged-off. 9. LOSS – Charge-off Credit is considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification is for charged-off loans but does not mean that the asset has absolutely no recovery or salvage value. These loans are further characterized by: • Liquidation or reorganization under Bankruptcy, with poor prospects of collection. • Fraudulently overstated assets and/or earnings. • Collateral has marginal or no value. • Debtor cannot be located. • Over 120 days delinquent.

Typical modifications granted include, but are not limited to: • Agreeing to interest rates below prevailing market rates for debt with similar risk characteristics. • Extending the maturity date or amortization period beyond typical lending guidelines for loans with similar risk characteristics. • Agreeing to an interest-only payment structure, delaying principal payments, or delaying payments. • Forgiving principal. To determine if a borrower is experiencing financial difficulty, factors we consider include: • The borrower is currently in default on any debt. • The borrower would likely default on any debt if the concession is not granted. • The borrower’s cash flow is insufficient to service all debt if the concession is not granted. • The borrower has declared, or is in the process of declaring, bankruptcy. • The borrower is unlikely to continue as a going concern (if the entity is a business). The following is a summary of the amortized cost basis of loan modifications granted to borrowers experiencing financial difficulty for the nine-month period ended September 30, 2023. There were no loan modifications granted to borrowers experiencing financial difficulty for the three-month period ended September 30, 2023.

During the nine months ended September 30, 2022, there were two loans restructured, one with a below market interest rate of $55, and one with both a below market interest rate and extension of amortization period in the amount of $98. Total restructured loans at September 30, 2022 was $153. We closely monitor the performance of loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of our modification efforts. Loans modified during the nine-month period ended September 30, 2023 were all current at September 30, 2023, with no loans in past due status. We had no loans that defaulted in the three and nine-month periods ended September 30, 2023 and 2022 which were modified within 12 months prior to the default date. ACL - Loans The credit quality of our loan portfolio is continuously monitored and is reflected within the ACL for loans. The ACL is an estimate of expected losses inherent within our loan portfolio. The ACL is adjusted by a credit loss expense, which is reported in earnings, and reduced by the charge-off of loan amounts, net of recoveries. The ACL is evaluated on a regular basis for appropriateness. Our periodic review of the collectability of a loan considers historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The primary factors behind the determination of the level of the ACL are specific allocations for loans individually evaluated, historical loss percentages, delinquency status, and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense in those future periods. The methodology for estimating the amount of expected credit losses reported in the ACL has two basic components: a component of individual loans that do not share risk characteristics with other loans; and a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics. For a loan that does not share risk characteristics with other loans, an individual analysis is performed to measure an allowance. Loans in nonaccrual status are individually evaluated for specific allocation of the allowance using the fair value of collateral, less costs to sell if foreclosure is probable, or the discounted cash flow method. We do not recognize interest income on loans in nonaccrual status. For loans not classified as nonaccrual, interest income is recognized daily, as earned, according to the terms of the loan agreement and the principal amount outstanding. In determining the allowance for credit losses, we derive an estimated credit loss assumption from a model that categorizes loan pools based on loan type and credit risk ratings or delinquency bucket. This model calculates an expected loss percentage for each loan class by considering the probability of default, based on the migration of loans from performing to loss by credit risk ratings or delinquency buckets using life-of-loan analysis, and the historical severity of loss, based on the aggregate net lifetime losses incurred per loan class. The default and severity factors used to calculate the allowance for credit losses for loans that share similar risk characteristics with other loans are adjusted for differences between the historical period used to calculate historical default and loss severity rates and expected conditions over the remaining lives of the loans in the portfolio. These qualitative factors are used to adjust the historical probabilities of default and severity of loss so that they reflect management's expectation of future conditions based on a reasonable and supportable forecast. To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made, the model reverts back to the historical rates of default and severity of loss. Qualitative factors include: • Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, recovery practices not considered elsewhere in estimating credit losses; • Changes in the experience, ability, and depth of lending management and other relevant staff; • Changes in interest rates; • Changes in international, national, regional, and local economic factors (international, national, regional, and local); • Changes in the nature and volume of the portfolio and in the terms of loans; • Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans; • Lack of current financial information; • Competition, Legal, and Regulatory; and • Changes in the value of underlying collateral. Upon the adoption of ASC 326, the estimated ACL using the CECL methodology increased $2,744 compared to the ACL as of December 31, 2022 using the prior incurred loss model. The manner in which credit loss allowances are allocated to the individual portfolio segments was partly impacted by a change in the way the underlying loans within each segment are pooled for modeling purposes. The impact of varying economic conditions and portfolio risk factors are now a component of the credit loss models applied to each modeling pool. In that regard, the amounts allocated to the underlying pools of loans within each portfolio segment more directly reflect the economic variables and portfolio stress factors that correlate with credit losses within each portfolio. Under the prior methodology, allocations in excess of those derived from historical loss rates were reco

Share-based Payment Arrangement [Text Block]	Restricted Stock Plan Under the RSP, an equity-based bonus plan, we award restricted stock bonuses to eligible employees on an annual basis that are not fully transferable or vested until certain conditions are met. Currently, the eligible employees are the Bank's CEO, President, and CFO. The RSP authorizes the issuance of unvested restricted stock to an eligible employee with a maximum award ranging from 25% to 40% of the employee’s annual salary, on a calendar year basis. The employee must also satisfy the annual performance targets and measures established by the Board of Directors. If these grant conditions are not satisfied, then the award of restricted shares will lapse or be adjusted appropriately, at the discretion of the Board of Directors. All such Grant Agreements contain vesting conditions and clawback provisions.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Under fair value measurement and disclosure authoritative guidance, we group assets and liabilities measured at fair value into three levels, based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine fair value, based on the prioritization of inputs in the valuation techniques. These levels are: Level 1: Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2: Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3: Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. Transfers between measurement levels are recognized at the end of reporting periods. Fair value measurement requires the use of an exit price notion which may differ from entrance pricing. Generally, we believe our assets and liabilities classified as Level 1 or Level 2 approximate an exit price notion. Following is a description of the valuation methodologies, key inputs, and an indication of the level of the fair value hierarchy in which the assets or liabilities are classified. AFS securities: AFS securities are recorded at fair value on a recurring basis. Level 1 fair value measurement is based upon quoted prices for identical instruments. Level 2 fair value measurement is based upon quoted prices for similar instruments. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss and liquidity assumptions. The values for Level 1 and Level 2 investment securities are generally obtained from an independent third party. On a quarterly basis, we compare the values provided to alternative pricing sources. Loans: We do not record loans at fair value on a recurring basis. However, some loans are individually evaluated for ACL purposes, and a specific ACL may be established. To measure reserve, the fair value of the loan is estimated using the fair value of the collateral, less costs to sell if foreclosure is probable, or the present value of expected future cash flows discounted at the loan’s effective interest rate. Loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. We review the net realizable values of the underlying collateral for collateral dependent loans on at least a quarterly basis for all loan types. To determine the collateral value, we utilize independent appraisals, broker price opinions, or internal evaluations. We review these valuations to determine whether an additional discount should be applied given the age of market information that may have been considered as well as other factors such as costs to sell an asset if it is determined that the collateral will be liquidated in connection with the ultimate settlement of the loan. We use these valuations to determine if any specific reserves or charge-offs are necessary. We may obtain new valuations in certain circumstances, including when there has been significant deterioration in the condition of the collateral, if the foreclosure process has begun, or if the existing valuation is deemed to be outdated. The following tables list the quantitative information about loans measured at fair value on a nonrecurring basis as of: September 30, 2023 Valuation Technique Fair Value Unobservable Input Actual Range Weighted Average Collateral Dependent Loans - Discount applied to collateral: Discounted value $391 Real Estate 20% 20% Equipment 25% 25% December 31, 2022 Valuation Technique Fair Value Unobservable Input Actual Range Weighted Average Discount applied to collateral: Real Estate 20% - 30% 24% Impaired Loans - Equipment 25% - 35% 31% Discounted value $17,143 Cash crop inventory 40% 40% Livestock 30% 30% Accounts receivable 25% 27% Furniture, fixtures & equipment 45% 45% Collateral discount rates may have ranges to accommodate differences in the age of the independent appraisal, broker price opinion, or internal evaluation. OMSR: OMSR (which are included in other assets) are subject to impairment testing. To test for impairment, we utilize a discounted cash flow analysis using interest rates and prepayment speed assumptions currently quoted for comparable instruments and discount rates. If the valuation model reflects a value less than the carrying value, OMSR are adjusted to fair value through a valuation allowance as determined by the model. As such, we classify OMSR subject to nonrecurring fair value adjustments as Level 2. The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Although we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement. Estimated Fair Values of Financial Instruments Not Recorded at Fair Value in their Entirety on a Recurring Basis Disclosure of the estimated fair values of financial instruments, which differ from carrying values, often requires the use of estimates. In cases where quoted market values in an active market are not available, we use present value techniques and other valuation methods to estimate the fair values of our financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used.

Available-for-sale Securities	ACL - AFS Securities: AFS securities are reviewed quarterly for possible credit impairment. In determining whether a credit-related impairment exists for debt securities, we assess whether: (a) we do not have the intent to sell the security; and (b) it is more likely than not we will not have to sell the security before recovery of its cost basis. If either of these conditions are met, any previously recognized allowances are charged-off and the security's amortized cost is written down to fair value through income. If these conditions are not met, the security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In order to determine the amount of the credit loss for a debt security, we calculate the recovery value by performing a discounted cash flow analysis based on the current cash flows and future cash flows we expect to recover. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. The amount of the impairment related to other risk factors is recognized as a component of other comprehensive income. Adjustments to the allowance are reported in the income statement as a provision for credit losses. We made an accounting policy election to exclude accrued interest receivable on AFS securities from the estimate of credit losses. AFS securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management, or when criteria regarding intent or requirement to sell is met.
Nonaccrual Loan Status	The accrual of interest on commercial and agricultural loans, as well as residential real estate loans, is discontinued at the time a loan is 90 days or more past due unless the credit is well-secured and in the process of short-term collection. Upon transferring a loan to nonaccrual status, we perform an evaluation to determine the net realizable value of the underlying collateral. This evaluation is used to help determine if a charge-off is necessary. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on the contractual term of the loan. In all cases, a loan is placed in nonaccrual status at an earlier date if collection of principal or interest is considered doubtful. When a loan is placed in nonaccrual status, all interest accrued in the current calendar year, but not collected, is reversed against interest income while interest accrued in prior calendar years, but not collected, is charged against the ACL. Loans may be returned to accrual status after six months of continuous performance and achievement of current payment status.
Loans Receivable	Loans that we have the intent and ability to hold in our portfolio are reported at their outstanding principal balance adjusted for any charge-offs, the ACL, and deferred fees or costs. Unless a loan has a nonaccrual status, interest income is accrued over the term of the loan based on the principal amount outstanding. Loan origination fees and certain direct loan origination costs are capitalized and recognized as a component of interest income over the term of the loan using the appropriate amortization method. Commercial and agricultural loans include loans for commercial real estate, commercial operating loans, advances to mortgage brokers, farmland and agricultural production, and loans to states and political subdivisions. Repayment of these loans is dependent upon the successful operation and management of a business. We minimize our risk by limiting the amount of direct credit exposure to any one borrower to $18,000. Borrowers with direct credit needs of more than $18,000 may be serviced through the use of loan participations with other commercial banks. Commercial and agricultural real estate loans commonly require loan-to-value limits of 80% or less. Depending upon the type of loan, past credit history, and current operating results, we may require the borrower to pledge accounts receivable, inventory, property, or equipment. Government agency guarantee may be required. Personal guarantees and/or life insurance beneficiary assignments are generally required from the owners of closely held corporations, partnerships, and sole proprietorships. In addition, we may require annual financial statements, prepare cash flow analyses, and review credit reports. We offer adjustable rate mortgages, construction loans, and fixed rate residential real estate loans which have amortization periods up to a maximum of 30 years. We consider the anticipated direction of interest rates, balance sheet duration, the sensitivity of our balance sheet to changes in interest rates, our liquidity needs, and overall loan demand to determine whether or not to sell fixed rate loans to Freddie Mac. Our lending policies generally limit the maximum loan-to-value ratio on residential real estate loans to 100% of the lower of the appraised value of the property or the purchase price. Private mortgage insurance is typically required on loans with loan-to-value ratios in excess of 80% unless the loan qualifies for government guarantees. Underwriting criteria for originated residential real estate loans generally include: • Evaluation of the borrower’s ability to make monthly payments. • Evaluation of the value of the property securing the loan. • Ensuring the payment of principal, interest, taxes, and hazard insurance generally does not exceed 28% of a borrower’s gross income. • Ensuring all debt servicing does not exceed 40% of income. • Verification of acceptable credit reports. • Verification of employment, income, and financial information. Appraisals are performed by independent appraisers and are reviewed for appropriateness. Generally, mortgage loan requests are reviewed by our mortgage loan committee or through a secondary market underwriting system; loans in excess of $1,000 require the approval of one or more of the following committees: Internal Loan Committee, the Executive Loan Committee, or the Board of Directors. Consumer loans include secured and unsecured personal loans. Loans are amortized for a period of up to 15 years based on the age and value of the underlying collateral. The underwriting emphasis is on a borrower’s perceived intent and ability to pay rather than collateral value. No consumer loans are sold to the secondary market.
Internal Credit Risk Ratings	Internally assigned credit risk ratings are reviewed, at a minimum, when loans are renewed or when management has knowledge of improvements or deterioration of the credit quality of individual credits. Descriptions of the internally assigned credit risk ratings for commercial and agricultural loans are as follows: 1. EXCELLENT – Substantially Risk Free Credit has strong financial condition and solid earnings history, characterized by: • High liquidity, strong cash flow, low leverage. • Unquestioned ability to meet all obligations when due. • Experienced management, with management succession in place. • Secured by cash. 2. HIGH QUALITY – Limited Risk Credit with sound financial condition and a positive trend in earnings supplemented by: • Favorable liquidity and leverage ratios. • Ability to meet all obligations when due. • Management with successful track record. • Steady and satisfactory earnings history. • If loan is secured, collateral is of high quality and readily marketable. • Access to alternative financing. • Well defined primary and secondary source of repayment. • If supported by guaranty, the financial strength and liquidity of the guarantor(s) are clearly evident. 3. HIGH SATISFACTORY – Reasonable Risk Credit with satisfactory financial condition and further characterized by: • Working capital adequate to support operations. • Cash flow sufficient to pay debts as scheduled. • Management experience and depth appear favorable. • Loan performing according to terms. • If loan is secured, collateral is acceptable and loan is fully protected. 4. LOW SATISFACTORY – Acceptable Risk Credit with bankable risks, although some signs of weaknesses are shown: • Would include most start-up businesses. • Occasional instances of trade slowness or repayment delinquency – may have been 10-30 days slow within the past year. • Management’s abilities are apparent yet unproven. • Weakness in primary source of repayment with adequate secondary source of repayment. • Loan structure generally in accordance with policy. • If secured, loan collateral coverage is marginal. To be classified as less than satisfactory, only one of the following criteria must be met. 5. SPECIAL MENTION – Criticized Credit constitutes an undue and unwarranted credit risk but not to the point of justifying a classification of substandard. The credit risk may be relatively minor yet constitutes an unwarranted risk in light of the circumstances surrounding a specific loan: • Downward trend in sales, profit levels, and margins. • Impaired working capital position. • Cash flow is strained in order to meet debt repayment. • Loan delinquency (30-60 days) and overdrafts may occur. • Shrinking equity cushion. • Diminishing primary source of repayment and questionable secondary source. • Management abilities are questionable. • Weak industry conditions. • Litigation pending against the borrower. • Loan may need to be restructured to improve collateral position or reduce payments. • Collateral or guaranty offers limited protection. • Negative debt service coverage, however the credit is well collateralized and payments are current. 6. SUBSTANDARD – Classified Credit is inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged. There is a distinct possibility we will implement collection procedures if the loan deficiencies are not corrected. Any commercial loan placed in nonaccrual status will be rated “7” or worse. In addition, the following characteristics may apply: • Sustained losses have severely eroded the equity and cash flow. • Deteriorating liquidity. • Serious management problems or internal fraud. • Original repayment terms liberalized. • Likelihood of bankruptcy. • Inability to access other funding sources. • Reliance on secondary source of repayment. • Litigation filed against borrower. • Interest non-accrual may be warranted. • Collateral provides little or no value. • Requires excessive attention of the loan officer. • Borrower is uncooperative with loan officer. 7. VULNERABLE – Classified Credit is considered “Substandard” and warrants placing in nonaccrual status. Risk of loss is being evaluated and exit strategy options are under review. Other characteristics that may apply: • Insufficient cash flow to service debt. • Minimal or no payments being received. • Limited options available to avoid the collection process. • Transition status, expect action will take place to collect loan without immediate progress being made. 8. DOUBTFUL – Workout Credit has all the weaknesses inherent in a “Substandard” loan with the added characteristic that collection and/or liquidation is pending. The possibility of a loss is extremely high, but its classification as a loss is deferred until liquidation procedures are completed, or reasonably estimable. Other characteristics that may apply: • Normal operations are severely diminished or have ceased. • Seriously impaired cash flow. • Original repayment terms materially altered. • Secondary source of repayment is inadequate. • Survivability as a “going concern” is impossible. • Collection process has begun. • Bankruptcy petition has been filed. • Judgments have been filed. • Portion of the loan balance has been charged-off. 9. LOSS – Charge-off Credit is considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification is for charged-off loans but does not mean that the asset has absolutely no recovery or salvage value. These loans are further characterized by: • Liquidation or reorganization under Bankruptcy, with poor prospects of collection. • Fraudulently overstated assets and/or earnings. • Collateral has marginal or no value. • Debtor cannot be located. • Over 120 days delinquent.
Fair Value Measurement, Policy [Policy Text Block]	Under fair value measurement and disclosure authoritative guidance, we group assets and liabilities measured at fair value into three levels, based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine fair value, based on the prioritization of inputs in the valuation techniques. These levels are: Level 1: Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2: Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3: Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. Transfers between measurement levels are recognized at the end of reporting periods. Fair value measurement requires the use of an exit price notion which may differ from entrance pricing. Generally, we believe our assets and liabilities classified as Level 1 or Level 2 approximate an exit price notion.
Policy Loans Receivable, Policy	Loans: Loans that we have the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balance adjusted for any charge-offs, the ACL, and any deferred fees or costs. Interest income on loans is accrued over the term of the loan based on the principal amount outstanding. Loan origination fees and certain direct loan origination costs are capitalized and recognized as a component of interest income over the term of the loan using the appropriate yield methods. The accrual of interest on agricultural, commercial and mortgage loans is discontinued at the time the loan is 90 days or more past due unless the credit is well secured and in the process of collection. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed in nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. For loans that are placed on nonaccrual status or charged-off, all interest accrued in the current calendar year, but not collected, is reversed against interest income while interest accrued in prior calendar years, but not collected is charged against the ACL. Interest income on loans in
Credit Loss, Financial Instrument	ACL - Loans: The ACL on loans is calculated in accordance with ASC 326 and is deducted from the amortized cost basis of loans to present our best estimate of the net amount expected to be collected. The ACL is established through a provision for credit losses charged to earnings. Loan losses are charged against the allowance when we believe the uncollectability of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. We made an accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses. We evaluate the ACL on a regular basis. Our periodic review of the collectability of loans considers historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, prevailing economic conditions, and reasonable and supportable forecasts. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The ACL consists of a general component and loans individually analyzed. The general component covers loans not specifically analyzed and is based on historical loss experience, current conditions, and reasonable and supportable forecasts. The general component also includes uncertainties that we believe could affect our estimate of probable losses based on qualitative factors. Loans in nonaccrual status are individually analyzed on a loan-by-loan basis. Loans evaluated individually are not included in the general, or pooled, component of the ACL. For collateralized loans, the loan's specific allowance is measured by the fair value of the collateral approach. The specific reserve is based on the fair value of the collateral, less costs to sell if foreclosure is probable, and an allowance is established when the collateral value is lower than the carrying value of the loan. When the discounted cash flow method is used to measure the loan's specific allowance, the effective interest rate is used to discount expected cash flows to incorporate expected prepayments. An allowance is established when the discounted cash flows are lower than the carrying value of the loan. For large groups of smaller-balance, homogeneous loans, we may collectively evaluate these loans for measurement of an allowance. Off Balance Sheet Credit Related Financial Instruments: In the ordinary course of business, we enter into commitments to extend credit, including commitments under credit card arrangements, commercial lines of credit, home equity lines of credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded only when funded. In connection with these commitments, we established an allowance for credit losses related to off-balance-sheet credit exposures. The allowance, recorded in a liability account, is calculated in accordance with ASC 326 and represents expected credit losses over the contractual period for which we are exposed to credit risk resulting from a contractual obligation to extend credit. The estimate of expected credit losses considers both the likelihood that funding will occur and the amount expected to be funded over the estimated remaining life of the commitment. The likelihood and expected amount of funding are based on historical utilization rates. No allowance is recognized if we have the unconditional right to cancel the obligation. The allowance is reported as a component of accrued interest payable and other liabilities in our consolidated balance sheets. Adjustments to the allowance are reported in our income statement as a component of provision for credit losses.

Receivables [Abstract]
Allowance for Loan Losses	The credit quality of our loan portfolio is continuously monitored and is reflected within the ACL for loans. The ACL is an estimate of expected losses inherent within our loan portfolio. The ACL is adjusted by a credit loss expense, which is reported in earnings, and reduced by the charge-off of loan amounts, net of recoveries. The ACL is evaluated on a regular basis for appropriateness. Our periodic review of the collectability of a loan considers historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The primary factors behind the determination of the level of the ACL are specific allocations for loans individually evaluated, historical loss percentages, delinquency status, and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense in those future periods. The methodology for estimating the amount of expected credit losses reported in the ACL has two basic components: a component of individual loans that do not share risk characteristics with other loans; and a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics. For a loan that does not share risk characteristics with other loans, an individual analysis is performed to measure an allowance. Loans in nonaccrual status are individually evaluated for specific allocation of the allowance using the fair value of collateral, less costs to sell if foreclosure is probable, or the discounted cash flow method. We do not recognize interest income on loans in nonaccrual status. For loans not classified as nonaccrual, interest income is recognized daily, as earned, according to the terms of the loan agreement and the principal amount outstanding. In determining the allowance for credit losses, we derive an estimated credit loss assumption from a model that categorizes loan pools based on loan type and credit risk ratings or delinquency bucket. This model calculates an expected loss percentage for each loan class by considering the probability of default, based on the migration of loans from performing to loss by credit risk ratings or delinquency buckets using life-of-loan analysis, and the historical severity of loss, based on the aggregate net lifetime losses incurred per loan class. The default and severity factors used to calculate the allowance for credit losses for loans that share similar risk characteristics with other loans are adjusted for differences between the historical period used to calculate historical default and loss severity rates and expected conditions over the remaining lives of the loans in the portfolio. These qualitative factors are used to adjust the historical probabilities of default and severity of loss so that they reflect management's expectation of future conditions based on a reasonable and supportable forecast. To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made, the model reverts back to the historical rates of default and severity of loss. Qualitative factors include: • Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, recovery practices not considered elsewhere in estimating credit losses; • Changes in the experience, ability, and depth of lending management and other relevant staff; • Changes in interest rates; • Changes in international, national, regional, and local economic factors (international, national, regional, and local); • Changes in the nature and volume of the portfolio and in the terms of loans; • Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans; • Lack of current financial information; • Competition, Legal, and Regulatory; and • Changes in the value of underlying collateral. Upon the adoption of ASC 326, the estimated ACL using the CECL methodology increased $2,744 compared to the ACL as of December 31, 2022 using the prior incurred loss model. The manner in which credit loss allowances are allocated to the individual portfolio segments was partly impacted by a change in the way the underlying loans within each segment are pooled for modeling purposes. The impact of varying economic conditions and portfolio risk factors are now a component of the credit loss models applied to each modeling pool. In that regard, the amounts allocated to the underlying pools of loans within each portfolio segment more directly reflect the economic variables and portfolio stress factors that correlate with credit losses within each portfolio. Under the prior methodology, allocations in excess of those derived from historical loss rates were recognized as unallocated. Nonetheless, despite fluctuations in the allocation of portions of the overall allowance to the various portfolio segments, the entire allowance is available to absorb any credit losses within the entire loan portfolio.

Credit Loss, Financial Instrument		ACL - Loans: The ACL on loans is calculated in accordance with ASC 326 and is deducted from the amortized cost basis of loans to present our best estimate of the net amount expected to be collected. The ACL is established through a provision for credit losses charged to earnings. Loan losses are charged against the allowance when we believe the uncollectability of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. We made an accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses. We evaluate the ACL on a regular basis. Our periodic review of the collectability of loans considers historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, prevailing economic conditions, and reasonable and supportable forecasts. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The ACL consists of a general component and loans individually analyzed. The general component covers loans not specifically analyzed and is based on historical loss experience, current conditions, and reasonable and supportable forecasts. The general component also includes uncertainties that we believe could affect our estimate of probable losses based on qualitative factors. Loans in nonaccrual status are individually analyzed on a loan-by-loan basis. Loans evaluated individually are not included in the general, or pooled, component of the ACL. For collateralized loans, the loan's specific allowance is measured by the fair value of the collateral approach. The specific reserve is based on the fair value of the collateral, less costs to sell if foreclosure is probable, and an allowance is established when the collateral value is lower than the carrying value of the loan. When the discounted cash flow method is used to measure the loan's specific allowance, the effective interest rate is used to discount expected cash flows to incorporate expected prepayments. An allowance is established when the discounted cash flows are lower than the carrying value of the loan. For large groups of smaller-balance, homogeneous loans, we may collectively evaluate these loans for measurement of an allowance. Off Balance Sheet Credit Related Financial Instruments: In the ordinary course of business, we enter into commitments to extend credit, including commitments under credit card arrangements, commercial lines of credit, home equity lines of credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded only when funded. In connection with these commitments, we established an allowance for credit losses related to off-balance-sheet credit exposures. The allowance, recorded in a liability account, is calculated in accordance with ASC 326 and represents expected credit losses over the contractual period for which we are exposed to credit risk resulting from a contractual obligation to extend credit. The estimate of expected credit losses considers both the likelihood that funding will occur and the amount expected to be funded over the estimated remaining life of the commitment. The likelihood and expected amount of funding are based on historical utilization rates. No allowance is recognized if we have the unconditional right to cancel the obligation. The allowance is reported as a component of accrued interest payable and other liabilities in our consolidated balance sheets. Adjustments to the allowance are reported in our income statement as a component of provision for credit losses.
