AMES NATIONAL CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements (unaudited)

The accompanying unaudited consolidated financial statements have been prepared by Ames National Corporation (the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to those rules and regulations, although the company believes that the disclosures made are adequate to make the information not misleading. It is suggested that these interim financial statements be read in conjunction with the year-end audited financial statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 (the “Annual Report”). The consolidated balance sheet of the Company as of December 31, 2022 has been derived from the audited consolidated balance sheet of the Company as of that date. In the opinion of management, the accompanying consolidated financial statements of the Company contain all adjustments necessary to fairly present the financial results for the interim periods reported. Those adjustments consist only of normal recurring adjustments. The results of operations for the interim periods are not necessarily indicative of results which may be expected for an entire year. The consolidated financial statements include the accounts of the Company and its wholly-owned banking subsidiaries (the “Banks”). All significant intercompany balances and transactions have been eliminated in consolidation.

Subsequent Events: The Company has evaluated subsequent events through the filing date of this Quarterly Report on Form 10-Q with the SEC.

Reclassifications: Certain reclassifications have been made to the prior period’s consolidated financial statements to present them on a basis comparable with the current period’s consolidated financial statements. The reclassifications had no effect on stockholders’ equity and net income of the prior periods.

Goodwill: Goodwill represents the excess of cost over the fair value of net assets acquired. Goodwill resulting from acquisitions is not amortized, but is tested for impairment annually or whenever events change and circumstances indicate that it is more likely than not that an impairment loss has occurred. Goodwill is tested for impairment with an estimation of the fair value of a reporting unit.

The fair value of a reporting unit is the price that would be received to sell the unit as a whole in an orderly transaction between market participants at the measurement date. As none of the Company’s reporting units are publicly traded, individual reporting unit fair value determinations cannot be directly correlated to the Company’s stock price. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions and selecting an appropriate control premium. The Company completed a quantitative assessment of goodwill as of October 1, 2022 which indicated that goodwill was not impaired. Subsequently, the Company determined there were no adverse changes in criteria and key considerations to the previous assessment. Accordingly, the Company concluded there is no impairment of goodwill as of March 31,June 30, 2023.

Adoption of New Financial Accounting Standard Codification 326 (ASC 326 (CECL)):

On January 1, 2023, the Company adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the recognition of the allowance for credit losses be estimated using the current expected credit loss (CECL) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet (OBS) credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with Topic 842 on leases. In addition, ASC 326 made changes to the accounting for available-for-sale debt securities. One such change is to require credit losses to be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell or believes that it is more likely than not they will be required to sell.

The Company adopted ASC 326 using the modified retrospective method for all financial assets measured at amortized cost and OBS 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. The Company recorded a net decrease to retained earnings of $603 thousand as of January 1, 2023 for the cumulative effect of adopting ASC 326, which includes deferred taxes of $188 thousand. The transition adjustment includes a $518 thousand increase to the Allowance for Credit Losses on loans and a $273 thousand increase to the Allowance for Credit Losses on OBS Credit Exposures.

The following table illustrates the impact of ASC 326 (amounts in thousands).

Available-For-Sale Debt Securities and the Allowance For Credit Losses On Available-For-Sale Debt Securities: Debt securities that we might not hold until maturity are classified as available for sale ("AFS") and are reported at the fair value in the balance sheet. Fair value measurement is based upon quoted market prices in active markets, if available. If quoted prices in active markets are not available, fair value is measured using pricing models or other model-based valuation techniques such as present value of future cash flows, which consider prepayment assumptions and other factors such as credit losses and market liquidity. Unrealized gains and losses are excluded from earnings and reported, net of tax, in other comprehensive income ("OCI"). Gains and losses on the sale of securities are determined using the specific identification method based on amortized cost and are reflected in results of operation at the time of sale. Interest and dividend income, adjusted by amortization of purchase premium or discount over the estimated life of the security or, in the case of callable securities, through the first call date, using the level yield method, is included in income as earned.

AFS debt securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. For AFS debt securities, a decline in fair value due to credit loss results in recording an allowance for credit losses to the extent the fair value is less than the amortized cost basis. Declines in fair value that have not been recorded through an allowance for credit losses, such as declines due to changes in market interest rates, are recorded through other comprehensive income, net of applicable taxes.

Impairment may result from credit deterioration of the issuer or collateral underlying the security. In performing an assessment of whether any decline in fair value is due to a credit loss, all relevant information is considered at the individual security level. For asset-backed securities performance indicators considered related to the underlying assets include default rates, delinquency rates, percentage of nonperforming assets, debt-to-collateral ratios, third-party guarantees, current levels of subordination, vintage, geographic concentration, analyst reports and forecasts, credit ratings and other market data. In assessing whether a credit loss exists, we compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis for the security, a credit loss exists and an allowance for credit losses is recorded, limited to the amount the fair value is less than amortized cost basis.

If we intend to sell a debt security or more likely than not we will be required to sell the security before recovery of its amortized cost basis, the debt security is written down to its fair value and the write down is charged against the allowance for credit losses with any incremental impairment reported in earnings.

Accrued interest receivable on AFS debt securities totaled $4.2$3.3 million at March 31,June 30, 2023 and is excluded from the estimate of credit losses.

Loans Held for Sale: Loans held for sale are stated at the lower of aggregate cost or estimated fair value. Loans are sold on a non-recourse basis with servicing released and gains and losses are recognized based on the difference between sales proceeds and the carrying value of the loan. The Company has had very few experiences of repurchasing loans previously sold into the secondary market. A specific reserve was not considered necessary based on the Company’s historical experience with repurchase activity.

Loans Held For Investment: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost net of the allowance for credit losses. Amortized cost is the principal balance outstanding, net of deferred loan fees and costs. Accrued interest receivable on loans held for investment totaled $6.3$7.2 million at March 31,June 30, 2023 and is excluded from the estimate of credit losses. Interest income is accrued on the unpaid principal balance. Nonrefundable loan fees and origination costs are deferred and recognized as a yield adjustment over the life of the related loan.

The policy for charging off loans is consistent throughout all loan categories. A loan is charged off based on criteria that includes but is not limited to: delinquency status, financial condition of the entire customer credit line and underlying collateral coverage, economic or external conditions that might impact full repayment of the loan, legal issues, overdrafts, and the customer’s willingness to work with the Company.

The accrual of interest income on loans is discontinued when, in the opinion of management, there is reasonable doubt as to the borrower's ability to meet payments of interest or principal when they become due, which is generally when a loan is 90 days or more past due unless the loan is well secured and in the process of collection. When a loan is placed on nonaccrual status, all previously accrued and unpaid interest is reversed against interest income. Loans are returned to an accrual status when all of the principal and interest amounts contractually due are brought current and repayment of the remaining contractual principal and interest is expected. A loan may also return to accrual status if additional collateral is received from the borrower and, in the opinion of management, the financial position of the borrower indicates that there is no longer any reasonable doubt as to the collection of the amount contractually due. Payment received on nonaccrual loans are applied first to principal. Once principal is recovered, any remaining payments received are applied to interest income.

Allowance for Credit Losses For Loans Held For Investment: Credit quality within the loans held for investment portfolio is continuously monitored by management and is reflected within the allowance for credit losses for loans. The allowance for credit losses is an estimate of expected losses inherent within the Company's existing loans held for investment portfolio. Expected credit loss inherent in non-cancelable off-balance-sheet credit exposures is accounted for as a separate liability on the balance sheet. The allowance for credit losses for loans held for investment, as reported in our consolidated balance sheet, 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 loan loss estimation process involves procedures to appropriately consider the unique characteristics of loan portfolio segments which consist of construction real estate, 1 to 4 family residential real estate, multi-family real estate, commercial real estate, agricultural real estate, commercial, agricultural and consumer and other lending. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. The key components in this estimation process include the following:

The Company primarily utilizes loss rate based undiscounted cash flow (UDCF) methods to estimate credit losses by portfolio segment. The UDCF methods obtain estimated life-time credit losses using the conceptual components described above.

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.

Credit quality is assessed and monitored by evaluating various attributes and the results of those evaluations are utilized in underwriting new loans and in our process for estimation of expected credit losses. The following provides the credit quality indicators and risk elements that are most relevant and most carefully considered and monitored for each loan portfolio segment.

Construction Real Estate – Construction loans are underwritten utilizing independent appraisals, sensitivity analysis of absorption, vacancy and lease rates and financial analysis of the developers and property owners. Construction loans are generally based upon estimates of costs and value associated with the completed project. These estimates may prove to be inaccurate primarily due to unforeseen circumstances beyond the control of the borrower or lender. Construction loans often involve the disbursement of funds with repayment substantially dependent on the success of the ultimate project. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, general economic conditions and the availability of long-term financing. The Company may require guarantees on these loans. The Company’s construction loans are secured primarily by properties located in its primary market area. National unemployment rate is a key economic forecast used in estimating expected credit losses for this segment.

1-4 Family Residential Real Estate – The Company originates 1-4 family real estate loans utilizing credit reports to supplement the underwriting process. The Company’s underwriting standards for 1-4 family loans are generally in accordance with FHLMC and FNMA manual underwriting guidelines. Properties securing 1-4 family real estate loans are appraised by either staff appraisers or fee appraisers, both of which are independent of the loan origination function and have been approved by the Board of Directors. The loan-to-value ratios normally do not exceed 90% without credit enhancements such as mortgage insurance. The Company will lend up to 100% of the lesser of the appraised value or purchase price for conventional 1-4 family real estate loans, provided private mortgage insurance is obtained. The Company’s 1-4 family real estate loans are secured primarily by properties located in its primary market area. The national unemployment rate is a key economic forecast used in estimating expected credit losses for this segment.

Multi-family, Commercial and Agricultural Real Estate – Multi-family, commercial and agricultural real estate loans are subject to underwriting standards and processes similar to commercial and agricultural operating loans, in addition to those unique to real estate loans. These loans are viewed primarily as cash flow loans and, secondarily, as loans secured by real estate. Multi-family, commercial and agricultural real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Loan-to-value generally does not exceed 80% of the cost or value of the assets. Loans are typically subject to interest rate adjustments between five and seven years from origination. Fully amortized monthly repayment terms normally do not exceed twenty-five years. Projections and cash flows that show ability to service debt within the amortization period are required. Property and casualty insurance is required to protect the Banks’ collateral interests. Appraisals on properties securing these loans are generally performed by fee appraisers approved by the Board of Directors. Because payments on multi-family, commercial and agricultural real estate loans are often dependent on the successful operation or management of the properties, repayment of such loans may be subject to adverse conditions in the real estate market or the economy. Management monitors and evaluates commercial and agricultural real estate loans based on collateral and risk rating criteria. The Company may require guarantees on these loans. The Company’s multi-family, commercial and agricultural real estate loans are secured primarily by properties located in its primary market areas. The national unemployment rate and the national real gross domestic product (GDP) are key economic forecasts used in estimating expected credit losses for the multi-family and commercial real estate segments. The national real GDP is a key economic forecast used in estimating expected credit losses for the agricultural real estate segment.

Commercial and Agricultural – Commercial and agricultural operating loans are underwritten based on the Company’s examination of current and projected cash flows to determine the ability of the borrower to repay their obligations as agreed. This underwriting includes the evaluation of cash flows of the borrower, underlying collateral, if applicable, and the borrower’s ability to manage its business activities. The cash flows of borrowers and the collateral securing these loans may fluctuate in value after the initial evaluation. A first priority lien on the general assets of the business normally secures these types of loans. Loan-to-value limits vary and are dependent upon the nature and type of the underlying collateral and the financial strength of the borrower. Crop and hail insurance is required for most agricultural borrowers. Loans are generally guaranteed by the principal(s). The Company’s commercial and agricultural operating lending is primarily in its primary market area. The national unemployment rate and the national real GDP are key economic forecasts used in estimating expected credit losses for the commercial operating segment. The national real GDP is a key economic forecast used in estimating expected credit losses for the agricultural operating segment.

Consumer and Other – Consumer and other loans utilize credit reports to supplement the underwriting process. The underwriting standards include a determination of the applicant’s payment history on other debts and an assessment of their ability to meet existing obligations and payments on the proposed loan. To monitor and manage loan risk, policies and procedures are developed and modified, as needed by management. This activity, coupled with smaller loan amounts that are spread across many individual borrowers, minimizes risk. Additionally, market conditions are reviewed by management on a regular basis. The Iowa real GDP and Iowa retail trade earnings are key economic forecasts used in estimating expected credit losses for this segment.

Determining the Contractual Term: Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company.

Credit Loss Measurement: The allowance level is influenced by loan volumes, loan credit quality indicator migration or delinquency status, historic loss experience 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 for credit losses has two basic components: first, an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans; and second, 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, expected credit loss is measured based on 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, we recognize expected credit loss 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 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 fair value of collateral used by the Company is determined by obtaining an observable market price or by obtaining a fair value from an independent, licensed or certified appraiser, using observable market data. This data includes information such as selling price of similar properties and capitalization rates of similar properties sold within the market, expected future cash flows or earnings of the subject property based on current market expectations, and other relevant factors. Each quarter management reviews all collateral-dependent loans on a loan-by-loan basis to determine whether updated appraisals or evaluations are necessary based on loan performance, collateral type and guarantor support. At times, the Company measures the fair value of collateral-dependent loans using appraisals or evaluations with dates prior to one year from the date of review. Third-party appraisals are obtained from a pre-approved list of independent, third-party, local appraisal firms maintained by the credit underwriting department.department or the Company’s appraiser. Approval and addition to the list is based on experience, reputation, character, consistency and knowledge of the respective real estate market. Generally, appraisals are internally reviewed to ensure the quality of the appraisal and the expertise and independence of the appraiser. Once the expected credit loss amount is determined an allowance is provided for equal to the calculated expected credit loss and included in the allowance for credit losses. If the calculated expected credit loss is determined to be permanent or not recoverable, the amount of expected credit loss will be charged off. Factors considered by management in determining if the expected credit loss is permanent or not recoverable include whether management judges the loan to be uncollectible, repayment is deemed to be protracted beyond reasonable time frames, or the loss becomes evident owing to the borrower's lack of assets unless both well-secured and in the process of collection.

In estimating the component of the allowance for credit losses for loans that share similar risk characteristics with other loans, such loans are segregated into loan classes. Loans are designated into loan classes based on loans pooled by product types and similar risk characteristics or areas of risk concentration. 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 purpose. This model calculates an expected loss percentage for each loan class by considering the historical loss rate of similar peers. The loss rate 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 loss rates and expected conditions over the remaining lives of the loans in the portfolio related to: (1) lending policies and procedures; (2) international, national, regional and local economic business conditions and developments that affect the collectability of the portfolio; (3) the nature and volume of the loan portfolio including the terms of the loans; (4) the experience, depth, and ability of the lending management and other relevant staff; (5) the volume and severity of past due loans and other similar conditions; (6) the quality of our loan review system and (7) the value of underlying collateral for collateralized loans. Additional factors include the existence and effect of any concentrations of credit, and changes in the level of such 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. Such factors are used to adjust the historical loss rates so that they reflect management 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 Company reduces, on a straight-line basis over one year, the adjustments so that the model reverts back to the historical loss rates.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures, Including Unfunded Loan Commitments: The Company maintains a separate allowance for credit losses from off-balance-sheet credit exposures, including unfunded loan commitments, which is included in other liabilities. Management estimates the amount of expected losses by calculating a commitment usage factor over the contractual period for exposures that are not unconditionally cancellable by the Company 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 type. No credit loss estimate is reported for off-balance-sheet credit exposures that are unconditionally cancellable by the Company or for undrawn amounts under such arrangements that may be drawn prior to the cancellation of the arrangement. The allowance for credit losses on OBS credit exposures is adjusted as a credit loss expense. Categories of OBS credit exposures correspond to the loan portfolio segments described previously.

New and Pending Accounting Pronouncements:

In March 2023, the FASB issued ASU No. 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using Proportional Amortization Method. The ASU is intended to improve the accounting and disclosures for investments in tax credit structures. It allows reporting entities to elect to adopt for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The Company is currently evaluating the impact of the ASU on the Company's consolidated financial statements.

On February 8,May 10, 2023, the Company declared a cash dividend on its common stock, payable on MayAugust 15, 2023 to stockholders of record as of MayAugust 1, 2023, equal to $0.27 per share.

Earnings per share amounts were calculated using the weighted average shares outstanding during the periods presented. The weighted average outstanding shares for the three months ended March 31,June 30, 2023 and 2022 was 8,992,167 and 9,092,167,9,058,690, respectively. The weighted average outstanding shares for the six months ended June 30, 2023 and 2022 were 8,992,167 and 9,075,336, respectively. The Company had no potentially dilutive securities outstanding during the periods presented.

The Company is party to financial instruments with off-balance sheet risk in the normal course of business. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheet. No material changes in the Company’s off-balance sheet arrangements have occurred since December 31, 2022.

Assets and liabilities carried at fair value are required to be classified and disclosed according to the process for determining fair value. There are three levels of determining fair value.

Level 1: Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets.

Level 2: Inputs to the valuation methodology include: quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatility, prepayment speeds, credit risk); or inputs derived principally from or can be corroborated by observable market data by correlation or other means.         

Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Level 3 assets and liabilities include financial instruments whose value is determined using discounted cash flow methodologies, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

The following is a description of valuation methodologies used for assets and liabilities recorded at fair value on a recurring basis.

Securities available-for-sale: Level 1 securities include U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets. U.S. government agencies, mortgage-backed securities, state and political subdivisions, and most corporate bonds are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things.

Derivative financial instruments and loans receivable: The Company’s derivative financial instruments and loans receivable consist of interest rate swaps on loans accounted for as fair value hedges. The Company’s derivative financial instruments also include back-to-back loan swaps to assist customers in managing their interest rate risk while executing offsetting interest rate swaps with dealer counterparties. The Company's derivative positions and related loans are classified within Level 2 of the fair value hierarchy and are valued using models generally accepted in the financial services industry and that use actively quoted or observable market input values from external market data providers and/or non-binding broker-dealer quotations. The fair value of the derivatives and loans are determined using discounted cash flow models. These models’ key assumptions include the contractual terms of the respective contract along with significant observable inputs, including interest rates, yield curves, nonperformance risk and volatility.

The following table presents the balances of assets measured at fair value on a recurring basis by level as of March 31,June 30, 2023 and December 31, 2022 (in thousands):

Certain assets are measured at fair value on a nonrecurring basis; that is, they are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment or a change in previously recognized impairment).  The following table presents the assets carried on the balance sheet (after specific reserves) by caption and by level within the valuation hierarchy as of March 31,June 30, 2023 and December 31, 2022 (in thousands):

The significant inputs used in the fair value measurements for Level 3 assets measured at fair value on a nonrecurring basis as of March 31,June 30, 2023 and December 31, 2022 are as follows (in thousands):

* Not Meaningful.

Evaluations of the underlying assets are completed for each collateral dependent impaired loan with a specific reserve. The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate. Collateral evaluations are reviewed and discounted as appropriate based on knowledge of the specific type of collateral. In the case of real estate, an independent appraisal may be obtained. Types of discounts considered included aging of receivables, condition of the collateral, potential market for the collateral and estimated disposal costs. These discounts will vary from loan to loan, thus providing a range would not be meaningful.

GAAP requires disclosure of the fair value of financial assets and financial liabilities, including those that are not measured and reported at fair value on a recurring basis or nonrecurring basis. Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The following table includes the carrying amounts and estimated fair values of the Company’s financial assets and liabilities as of March 31,June 30, 2023 and December 31, 2022 (in thousands):

The methodologies used to determine fair value as of March 31,June 30, 2023 did not change from the methodologies described in the December 31, 2022 Annual Financial Statements.

Commitments to extend credit and standby letters of credit: The fair values of commitments to extend credit and standby letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and credit worthiness of the counterparties. The carrying value and fair value of the commitments to extend credit and standby letters of credit are not considered significant.

Limitations: Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.
