Notes to Financial Statements
Significant Accounting Policies [Text Block]	NOTE 1 Principles of Consolidation and Basis of Presentation The consolidated financial statements of Middlefield Banc Corp. ("Company") include its bank subsidiary, The Middlefield Banking Company (“MBC” or “Bank”), and a nonbank asset resolution subsidiary EMORECO, Inc. The consolidated financial statements also include the accounts of MBC’s subsidiaries, Middlefield Investments, Inc. (“MI”) and MB Insurance Services (“MIS”). All significant inter-company items have been eliminated. On March 13, 2019, March 31, 2024 may may not first 2022, March 31, 2024 December 1, 2022, not January 19, 2024. The unaudited consolidated financial statements have been prepared in conformity with the instructions to Form 10 10 not 10 December 31, 2023. not may The Company’s significant accounting policies involve the more significant judgments and assumptions used in the preparation of the consolidated financial statements as of March 31, 2024 Investments Management determines the appropriate classification of investment securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Investment securities classified as available for sale are those securities that the Bank intends to hold for an indefinite period of time but not Investment securities classified as held to maturity are those securities the Bank has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs, or changes in general economic conditions. These securities are carried at cost, adjusted for the amortization of premium and accretion of discount, and computed by a method that approximates the interest method over the terms of the securities. As of March 31, 2024 not Equity securities, which are included in other investments on the Consolidated Balance Sheet, are measured at fair value with changes in fair value recognized in net income. The Bank adopted ASU No. 2016 13 , Financial Instruments - Credit Loses - Topic ( 326 2016 13" , January 1, 2023. not not not The allowance for credit losses is included within investment securities available for sale on the Consolidated Balance Sheet. Changes in the allowance for credit losses are recorded within the provision for credit losses on the Consolidated Statement of Income. Losses are charged against the allowance when the Bank believes the collectability of an available-for-sale security is in jeopardy or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on available-for-sale investment securities totaled $1.6 million on March 31, 2024 90 Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at their outstanding unpaid principal balances, net of unearned income, which includes net deferred loan fees and costs and unamortized premiums and discounts. Accrued interest receivable is included within accrued interest receivable and other assets on the Consolidated Balance Sheet. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loans’ yield (interest income). The Bank amortizes these amounts over the contractual life of the loan. Premiums and discounts on purchased loans are amortized as adjustments to interest income using the effective yield method. Interest income is primarily recognized on an accrual basis according to formulas in written contracts, such as loan agreements. The loan portfolio is segmented into commercial and consumer loans. Commercial loans consist of the following classes: commercial construction, commercial and industrial loans, and commercial real estate loans. Consumer loans consist of the following classes: residential real estate loans, home equity loans, and consumer loans. For all classes of loans, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 may no The Bank adopted ASU 2016 13 , January 1, 2023. not The ACL is an estimate of expected credit losses, measured over the contractual life of a loan, that considers our historical loss experience, current conditions, and forecasts of future economic conditions. Determination of an appropriate ACL is inherently subjective and may Management uses a discounted cash flow ("DCF") model to calculate the present value of the expected cash flows for pools of loans that share similar risk characteristics and compares the results of this calculation to the amortized cost basis to determine its ACL balance. The contractual term used in projecting the cash flows of a loan is based on the maturity date of a loan and is adjusted for prepayment or curtailment assumptions, which may The key inputs to the DCF model are ( 1 2 3 4 5 6 7 Probability of Default ("PD") In order to incorporate economic factors into forecasting within the DCF model, management elected to use the Loss Driver method to generate the PD rate inputs. The Loss Driver method analyzes how one Loss Given Default ("LGD") Management elected to use the Frye Jacobs parameter for determining the LGD input, which is an estimation technique that derives an LGD input from segment-specific risk curves that correlate LGD with PD. Prepayment and Curtailment Rates Prepayment Rates: Loan-level transaction data is used to calculate semi-annual prepayment rates. These semi-annual rates are annualized, and the average of the annualized rates is used in the DCF calculation for fixed payments or term loans. Rates are calculated for each pool. Curtailment Rates: Loan-level transaction data is used to calculate annual curtailment rates using available historical loan-level data. The average of the historical rates is used in the DCF model for interest-only payment or line-of-credit type loans. Rates are calculated for each pool. Reasonable and Supportable Forecasts The forecast data used in the DCF model is obtained via a subscription to a widely recognized and relied-upon company that publishes various forecast scenarios. Management evaluates the various scenarios to determine a reasonable and supportable forecast. Forecast Reversion Period Management uses forecasts to predict how economic factors will perform and has determined to use a four eight Expected Recoveries on Charged-off Loans Management performs an analysis to estimate recoveries that could be reasonably expected based on historical experience in order to account for expected recoveries on loans that have already been fully charged off and are not Discount Rate The effective interest rate of the underlying loans of the Company serves as the discount rate applied to the expected periodic cash flows. Management adjusts the effective interest rate used to discount expected cash flows to incorporate expected prepayments. Individual Evaluation Management evaluates individual instruments for expected credit losses when those instruments do not not The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The Company’s loan portfolio is segmented to a level that allows management to monitor risk and performance. The portfolio is segmented into Commercial Real Estate (“CRE”), which is further segmented into Owner Occupied (“CRE OO”), Non-owner Occupied (“CRE NOO”), and Multifamily Residential, Residential Real Estate (“RRE”), Commercial and Industrial (“C&I”), Home Equity Lines of Credit (“HELOC”), Construction and Other (“Construction”), and Consumer Installment Loans. The CRE loan segments consist of loans made to finance the activities of CRE owners and operators and certain agricultural loans. The RRE and HELOC loan segments consist of loans made to finance the activities of residential homeowners. The C&I loan segment consists of loans made to finance the activities of commercial customers and certain agricultural loans. The consumer loan segment consists primarily of installment loans and overdraft lines of credit connected with customer deposit accounts. Historical credit loss experience is the basis for the estimation of expected credit losses. We apply historical loss rates to pools of loans with similar risk characteristics. After consideration of the historic loss calculation, management applies qualitative adjustments to reflect the current conditions and reasonable and supportable forecasts not The Bank has elected to exclude accrued interest receivable from the measurement of its ACL. When a loan is placed on nonaccrual status, any outstanding accrued interest is reversed against interest income. The ACL calculation for individual loans begins with the use of normal credit review procedures to identify whether a loan no third 2023, 1 2 3 not three 1 2 3 not The Bank adopted ASU No. 2016 13 January 1, 2023.

Fair Value Disclosures [Text Block]	NOTE 5 Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction between market participants at the measurement date. GAAP establishes a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following levels: Level I: Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Level II: Pricing inputs are other than the quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these assets and liabilities includes items for which quoted prices are available but traded less frequently and items that are valued using other financial instruments, the parameters of which can be directly observed. Level III: Assets and liabilities that have little to no not two This hierarchy requires the use of observable market data when available. The following tables present the assets measured at fair value on a recurring basis on the Consolidated Balance Sheet by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Level III securities are assets whose fair value cannot be determined by using observable measures. The inputs to the valuation methodology of these securities are unobservable and significant to the fair value measurement. Currently, this category includes certain subordinated debt investments that are valued based on the discounted cash flow approach assuming a yield curve of similarly structured instruments. While the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of specific financial instruments could result in a different estimate of fair value at the reporting date. Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not not may Equity Securities no not The following table presents the fair value reconciliation of Level III assets measured at fair value on a recurring basis.

Loans are individually analyzed when, based on current information and events, the Company will probably be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in evaluating credit loss include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall concerning the principal and interest owed. The evaluation of the need and amount of a specific allocation of the allowance and whether a loan can be removed from impairment status is made quarterly. Management uses a nine first five not not not 90 To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Company has a structured loan rating process with several layers of internal and external oversight. Generally, consumer and residential mortgage loans are included in the Pass categories unless a specific action, such as payment delinquency, bankruptcy, repossession, or death, occurs to raise awareness of a possible credit quality loss. The Company’s Commercial Loan Officers are responsible for the timely and accurate risk rating of the loans in their portfolios at origination and on an ongoing basis. The Credit Department performs an annual review of all commercial relationships with loan balances of $750,000 or greater. Detailed reviews, including plans for resolution, are performed on criticized loans of $150,000 or more on at least a quarterly basis. Loans in the Special Mention and Substandard categories that are collectively evaluated for impairment are given separate consideration in the determination of the allowance. Management further monitors the performance and credit quality of the loan portfolio by analyzing the age of the portfolio as determined by the length of time a recorded payment is past due.

Investment, Policy [Policy Text Block]	Investments Management determines the appropriate classification of investment securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Investment securities classified as available for sale are those securities that the Bank intends to hold for an indefinite period of time but not Investment securities classified as held to maturity are those securities the Bank has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs, or changes in general economic conditions. These securities are carried at cost, adjusted for the amortization of premium and accretion of discount, and computed by a method that approximates the interest method over the terms of the securities. As of March 31, 2024 not Equity securities, which are included in other investments on the Consolidated Balance Sheet, are measured at fair value with changes in fair value recognized in net income. The Bank adopted ASU No. 2016 13 , Financial Instruments - Credit Loses - Topic ( 326 2016 13" , January 1, 2023. not not not The allowance for credit losses is included within investment securities available for sale on the Consolidated Balance Sheet. Changes in the allowance for credit losses are recorded within the provision for credit losses on the Consolidated Statement of Income. Losses are charged against the allowance when the Bank believes the collectability of an available-for-sale security is in jeopardy or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on available-for-sale investment securities totaled $1.6 million on March 31, 2024 90
Financing Receivable [Policy Text Block]	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at their outstanding unpaid principal balances, net of unearned income, which includes net deferred loan fees and costs and unamortized premiums and discounts. Accrued interest receivable is included within accrued interest receivable and other assets on the Consolidated Balance Sheet. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loans’ yield (interest income). The Bank amortizes these amounts over the contractual life of the loan. Premiums and discounts on purchased loans are amortized as adjustments to interest income using the effective yield method. Interest income is primarily recognized on an accrual basis according to formulas in written contracts, such as loan agreements. The loan portfolio is segmented into commercial and consumer loans. Commercial loans consist of the following classes: commercial construction, commercial and industrial loans, and commercial real estate loans. Consumer loans consist of the following classes: residential real estate loans, home equity loans, and consumer loans. For all classes of loans, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 may no The Bank adopted ASU 2016 13 , January 1, 2023. not The ACL is an estimate of expected credit losses, measured over the contractual life of a loan, that considers our historical loss experience, current conditions, and forecasts of future economic conditions. Determination of an appropriate ACL is inherently subjective and may Management uses a discounted cash flow ("DCF") model to calculate the present value of the expected cash flows for pools of loans that share similar risk characteristics and compares the results of this calculation to the amortized cost basis to determine its ACL balance. The contractual term used in projecting the cash flows of a loan is based on the maturity date of a loan and is adjusted for prepayment or curtailment assumptions, which may The key inputs to the DCF model are ( 1 2 3 4 5 6 7 Probability of Default ("PD") In order to incorporate economic factors into forecasting within the DCF model, management elected to use the Loss Driver method to generate the PD rate inputs. The Loss Driver method analyzes how one Loss Given Default ("LGD") Management elected to use the Frye Jacobs parameter for determining the LGD input, which is an estimation technique that derives an LGD input from segment-specific risk curves that correlate LGD with PD. Prepayment and Curtailment Rates Prepayment Rates: Loan-level transaction data is used to calculate semi-annual prepayment rates. These semi-annual rates are annualized, and the average of the annualized rates is used in the DCF calculation for fixed payments or term loans. Rates are calculated for each pool. Curtailment Rates: Loan-level transaction data is used to calculate annual curtailment rates using available historical loan-level data. The average of the historical rates is used in the DCF model for interest-only payment or line-of-credit type loans. Rates are calculated for each pool. Reasonable and Supportable Forecasts The forecast data used in the DCF model is obtained via a subscription to a widely recognized and relied-upon company that publishes various forecast scenarios. Management evaluates the various scenarios to determine a reasonable and supportable forecast. Forecast Reversion Period Management uses forecasts to predict how economic factors will perform and has determined to use a four eight Expected Recoveries on Charged-off Loans Management performs an analysis to estimate recoveries that could be reasonably expected based on historical experience in order to account for expected recoveries on loans that have already been fully charged off and are not Discount Rate The effective interest rate of the underlying loans of the Company serves as the discount rate applied to the expected periodic cash flows. Management adjusts the effective interest rate used to discount expected cash flows to incorporate expected prepayments. Individual Evaluation Management evaluates individual instruments for expected credit losses when those instruments do not not The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The Company’s loan portfolio is segmented to a level that allows management to monitor risk and performance. The portfolio is segmented into Commercial Real Estate (“CRE”), which is further segmented into Owner Occupied (“CRE OO”), Non-owner Occupied (“CRE NOO”), and Multifamily Residential, Residential Real Estate (“RRE”), Commercial and Industrial (“C&I”), Home Equity Lines of Credit (“HELOC”), Construction and Other (“Construction”), and Consumer Installment Loans. The CRE loan segments consist of loans made to finance the activities of CRE owners and operators and certain agricultural loans. The RRE and HELOC loan segments consist of loans made to finance the activities of residential homeowners. The C&I loan segment consists of loans made to finance the activities of commercial customers and certain agricultural loans. The consumer loan segment consists primarily of installment loans and overdraft lines of credit connected with customer deposit accounts. Historical credit loss experience is the basis for the estimation of expected credit losses. We apply historical loss rates to pools of loans with similar risk characteristics. After consideration of the historic loss calculation, management applies qualitative adjustments to reflect the current conditions and reasonable and supportable forecasts not The Bank has elected to exclude accrued interest receivable from the measurement of its ACL. When a loan is placed on nonaccrual status, any outstanding accrued interest is reversed against interest income. The ACL calculation for individual loans begins with the use of normal credit review procedures to identify whether a loan no third 2023, 1 2 3 not three 1 2 3 not The Bank adopted ASU No. 2016 13 January 1, 2023.
