Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Nature of Operations Mid Penn Bancorp, Inc. ("Mid Penn" or the "Corporation"), through operations conducted by Mid Penn Bank (the "Bank") and its nonbank subsidiaries, engages in a full-service commercial banking and trust business, making available to the community a wide range of financial services, including, but not limited to, mortgage and home equity loans, secured and unsecured commercial and consumer loans, lines of credit, construction financing, farm loans, community development loans, loans to non-profit entities and local government loans, and various types of time and demand deposits including but not limited to, checking accounts, savings accounts, clubs, money market deposit accounts, certificates of deposit, and IRAs. In addition, the Bank provides a full range of trust and wealth management services through its Trust Department. Deposits are insured by the Federal Deposit Insurance Corporation ("FDIC") to the extent provided by law. Mid Penn also provides wealth management services, through its nonbank subsidiary MPB Wealth Management, LLC, and fulfills the insurance needs of both existing and potential customers through MPB Risk Services, LLC, doing business as MPB Insurance and Risk Management. The financial services are provided to individuals, partnerships, non-profit organizations, and corporations through its retail banking offices located in throughout Pennsylvania. Basis of Presentation For all periods presented, the accompanying Consolidated Financial Statements include the accounts of Mid Penn Bancorp, Inc., its wholly-owned subsidiary, Mid Penn Bank, and four nonbank subsidiaries, MPB Financial Services, LLC, which includes MPB Wealth Management, LLC and MPB Risk Services, LLC, and MPB Launchpad Fund I, LLC. As of December 31, 2023, the accounts and activities of these nonbank subsidiaries were not material to warrant separate disclosure or segment reporting. As a result, Mid Penn has only one reportable segment for financial reporting purposes. All material intercompany accounts and transactions have been eliminated in consolidation. For comparative purposes, the December 31, 2022 and December 31, 2021 balances have been reclassified, when necessary, to conform to the 2023 presentation. Such reclassifications had no impact on net income or total shareholders’ equity. In the opinion of management, all adjustments necessary for fair presentation of the periods presented have been reflected in the accompanying consolidated financial statements. All such adjustments are of a normal, recurring nature. Mid Penn has evaluated events and transactions occurring subsequent to the balance sheet date of December 31, 2023, for items that should potentially be recognized or disclosed in these consolidated financial statements. The evaluation was conducted through the issuance date of these consolidated financial statements. The accounting and reporting policies of Mid Penn conform with accounting principles generally accepted in the United States ("GAAP") and to general practice within the financial industry. Following is a description of the more significant accounting policies. Use of Estimates - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. Material estimates subject to significant change include the allowance for credit losses, the expected cash flows and collateral values associated with loans that are individually evaluated for credit losses, the carrying value of other real estate owned ("OREO"), the fair value of financial instruments, business combination fair value computations, the valuation of goodwill and other intangible assets, stock-based compensation and deferred income tax assets. Significant Group of Concentrations of Credit Risk - Most of the Corporation’s activities are with customers located within Pennsylvania. "Note 3 - In vestment Securities" discusses the types of investment securities in which the Corporation invests. "Note 4 - L oans and Allowance for Loan Losses" discusses the types of lending that the Corporation engages in as well as loan concentrations. The Corporation does not have a significant concentration of credit risk with any one customer. Fair Value Measurements - The Corporation uses estimates of fair value in applying various accounting standards for its consolidated financial statements on either a recurring or non-recurring basis. Fair value is defined as the price to sell an asset or transfer a liability in an orderly transaction between willing and able market participants. The Corporation groups its assets and liabilities measured at fair value in three hierarchy levels, based on the observability and transparency of the inputs. These levels are as follows Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities; Level 2 - Observable inputs other than level 1 inputs, including quoted prices for similar assets and liabilities, quoted prices for identical assets and liabilities in less active markets and other inputs that can be corroborated by observable market data; and Level 3 - Unobservable inputs supported by limited or no market activity or data and inputs requiring significant management judgment or estimation; valuation techniques utilizing level 3 inputs include option pricing models, discounted cash flow models and similar techniques. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. It is the Corporation’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs in estimating fair value. Unobservable inputs are utilized in determining fair value estimates only to the extent that observable inputs are not available. The need to use unobservable inputs generally results from a lack of market liquidity and trading volume. Transfers between levels of fair value hierarchy are recorded at the end of the reporting period. Cash and Cash Equivalents - For purposes of the Consolidated Statements of Cash Flows, cash and cash equivalents include cash on hand, balances due from banks, and federal funds sold, all of which mature within ninety days. Restrictions on Cash and Due from Bank Accounts - The Bank is required by banking regulations to maintain certain minimum cash reserves. As of both December 31, 2023 and 2022, there was no cash reserve balances required to be maintained at the Federal Reserve Bank of Philadelphia because the Bank had sufficient vault cash available. Debt Investment Securities - Mid Penn determines the classification of investment securities at the time of purchase. If Mid Penn has the intent and the ability at the time of purchase to hold debt securities until maturity, they are classified as held-to-maturity ("HTM"). HTM investment securities are stated at amortized cost. Debt securities Mid Penn does not intend to hold to maturity are classified as available for sale ("AFS") and carried at estimated fair value with unrealized gains or losses reported as a separate component of stockholders’ equity in accumulated other comprehensive income (loss), net of applicable income taxes. Available for sale securities are a part of Mid Penn’s asset/liability management strategy and may be sold in response to changes in interest rates, prepayment risk or other market factors. Management has elected to reclassify realized gains and losses from accumulated other comprehensive income when securities are sold on the trade date. Interest income and dividends on securities are recognized in interest income on an accrual basis. Premiums and discounts on debt securities are amortized as an adjustment to interest income over the period to maturity of the related security using the effective interest method. Realized gains or losses on the sale of securities are determined using the specific identification method. FASB ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," was adopted by Mid Penn on January 1, 2023. ASU 2016-13 introduces the CECL methodology for estimating allowances for credit losses. ASU 2016-13 applies to all financial instruments carried at amortized cost, including HTM securities, and makes targeted improvements to the accounting for credit losses on AFS securities. In order to comply with ASC 326, Mid Penn conducted a review of its investment portfolio and determined that for certain classes of securities it would be appropriate to assume the expected credit loss to be zero. This zero-credit loss assumption applies to debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. The reasons behind the adoption of the zero-credit loss assumption are as follows: •High credit rating •Long history with no credit losses •Guaranteed by a sovereign entity •Widely recognized as "risk-free rate" •Can print its own currency •Currency is routinely held by central banks, used in international commerce, and commonly viewed as reserve currency •Currently under the U.S. Government conservatorship or receivership Mid Penn will continuously monitor any changes in economic conditions, credit downgrades, changes to explicit or implicit guarantees granted to certain debt issuers, and any other relevant information that would indicate potential credit deterioration and prompt Mid Penn to reconsider its zero-credit loss assumption. At the date of adoption, Mid Penn’s estimated allowance for credit losses on AFS and HTM securities under ASU 2016-13 was deemed immaterial due to the composition of these portfolios. Both portfolios consist primarily of U.S. government agency guaranteed mortgage-backed securities for which the risk of loss is minimal. Therefore, Mid Penn did not recognize a cumulative effect adjustment through retained earnings related to the AFS and HTM securities. AFS Securities ASU 2016-13 makes targeted improvements to the accounting for credit losses on AFS securities. The concept of other-than-temporarily impaired has been replaced with the allowance for credit losses. Unlike HTM securities, AFS securities are evaluated on an individual level and pooling of securities is not allowed. Quarterly, Mid Penn evaluates if any security has a fair value less than its amortized cost. Once these securities are identified, in order to determine whether a decline in fair value resulted from a credit loss or other factors, Mid Penn performs further analysis as outlined below: •Review the extent to which the fair value is less than the amortized cost and observe the security’s lowest credit rating as reported by third-party credit ratings companies. •The securities that violate the credit loss triggers above would be subjected to additional analysis that may include, but is not limited to: changes in market interest rates, changes in securities credit ratings, security type, service area economic factors, financial performance of the issuer/or obligor of the underlying issue and third-party guarantee. •If Mid Penn determines that a credit loss exists, the credit portion of the allowance will be measured using a DCF analysis using the effective interest rate as of the security’s purchase date. The amount of credit loss Mid Penn records will be limited to the amount by which the amortized cost exceeds the fair value. The DCF analysis utilizes contractual maturities, as well as third-party credit ratings and cumulative default rates published annually by a reputable third-party. At December 31, 2023, the results of the analysis did not identify any securities that violate the credit loss triggers; therefore, no DCF analysis was performed and no credit loss was recognized on any of the securities available for sale. Accrued interest receivable is excluded from the estimate of credit losses for AFS securities. At December 31, 2023, accrued interest receivable totaled $1.3 million for AFS securities and was reported in accrued interest receivable on the accompanying Consolidated Balance Sheet. HTM Securities ASU 2016-13 requires institutions to measure expected credit losses on financial assets carried at amortized cost on a collective or pool basis when similar risks exist. Mid Penn uses several levels of segmentation in order to measure expected credit losses: •The portfolio is segmented into agency and non-agency securities. •The non-agency securities are separated into state and political subdivision obligations and corporate debt securities. Each individual segment is categorized by third-party credit ratings. As discussed above, Mid Penn has determined that for certain classes of securities it would be appropriate to assume the expected credit loss to be zero, which include debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. This assumption will be reviewed and attested to quarterly. At December 31, 2023, Mid Penn’s HTM securities totaled $399.1 million. After applying appropriate probability of default and loss given default assumptions, the total amount of current expected credit losses was deemed immaterial. Therefore, no reserve was recorded at December 31, 2023. Accrued interest receivable is excluded from the estimate of credit losses for HTM securities. At December 31, 2023, accrued interest receivable totaled $1.9 million for HTM securities and was reported in accrued interest receivable on the accompanying Consolidated Balance Sheet. At December 31, 2023, Mid Penn had no HTM securities that were past due 30 days or more as to principal or interest payments. Mid Penn had no HTM securities classified as nonaccrual at December 31, 2023. Equity Securities - The Corporation reports its equity securities with readily determinable fair values at fair value on the Consolidated Balance Sheet, with realized and unrealized gains and losses reported in other expense on the Consolidated Statements of Income. As of December 31, 2023 and 2022, Mid Penn’s equity securities consisted of Community Reinvestment Act funds totaling $438 thousand and $430 thousand, respectively. No equity securities were sold during the years ended December 31, 2023, 2022 and 2021. Federal Home Loan Bank ("FHLB") and Atlantic Community Bankers' Bank ("ACBB") Stock - The Bank is a member of the FHLB and the ACBB and is required to maintain an investment in the stock of the FHLB and ACBB. No market exists for these stocks, and the Bank’s investment can be liquidated only through redemption by the FHLB or ACBB, at the discretion of and subject to conditions imposed by the FHLB and ACBB. Historically, FHLB and ACBB stock redemptions have been at cost (par value), which equals the Corporation’s carrying value. The Corporation monitors its investment in FHLB and ACBB stock for impairment through review of recent financial results of the FHLB and ACBB including capital adequacy and liquidity position, dividend payment history, redemption history and information from credit agencies. The Corporation has not identified any indicators of impairment of FHLB or ACBB stock. During the years ended December 31, 2023, 2022, and 2021 dividends received from the FHLB totaled $864 thousand, $289 thousand, and $345 thousand respectively. Investment in Limited Partnership - Mid Penn is a limited partner in a partnership that provides low-income housing in Enola, Pennsylvania. The carrying value of Mid Penn’s investment in the limited partnership was $15 thousand at December 31, 2023 and $58 thousand at December 31, 2022, net of amortization, using the straight-line method and is reported in other assets on the Consolidated Balance Sheets. Mid Penn’s maximum exposure to loss is limited to the carrying value of its investment. Mid Penn also owns a limited partnership interest in a low-income housing project to construct thirty-seven apartments and common amenities in Dauphin County, Pennsylvania. The total investment in this limited partnership, net of amortization, was $4.5 million and $5.2 million on December 31, 2023 and December 31, 2022, respectively, and was included in the reported balance of other assets on the Consolidated Balance Sheet. All of the units qualified for Federal Low-Income Housing Tax Credits ("LIHTCs") as provided for in Section 42 of the Internal Revenue Code of 1986, as amended. Mid Penn’s limited partner capital contribution commitment is $7.6 million, and the investment was fully funded within a three-year period beginning in 2019 and ending during the first quarter of 2021. The investment in the limited partnership is reported in other assets on the Consolidated Balance Sheet and is being amortized over a ten-year period using the cost amortization method which began upon commencement of operations of the facility in December 2020. The project was formally awarded $8.5 million in total LIHTCs by the Pennsylvania Housing Finance Agency, which will be recognized over the ten-year period from December 2020 through November 2029. Mid Penn received low-income housing tax credits related to this project of $1.3 million for the tax year ended December 31, 2023 and $853 thousand for both of the tax years ended December 31, 2022 and 2021. Loans Held for Sale - During the third quarter of 2021, the Corporation made the election to measure mortgage loans held for sale at fair value. Derivative financial instruments related to mortgage banking activities are also recorded at fair value, as detailed under the heading "Mortgage Banking Derivative Financial Instruments," below. The Corporation determines fair value for its mortgage loans held for sale based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured. Changes in fair values during the period are recorded as components of mortgage banking income on the Consolidated Statements of Income. Interest income earned on mortgage loans held for sale is classified in interest income on the Consolidated Statements of Income. In periods prior to the third quarter of 2021, m ortgage loans originated and intended for sale in the secondary market were included in loans held for sale and were reported at the lower of cost or fair value, as determined by the aggregate commitments from investors or current investor yield requirements. Gains and losses on sales of mortgage loans are included in noninterest income in the Consolidated Statements of Income. Loans - Loans that management has the intent and ability to hold for the foreseeable future are reported at their outstanding principal balances, net of an allowance for loan losses, unamortized deferred fees and costs and unamortized premiums or discounts. The net amount of nonrefundable loan origination fees and certain direct costs associated with the lending process are deferred and amortized to interest income over the contractual lives of the loans using methods which approximate the level yield method. Discounts and premiums are amortized or accreted to interest income over the estimated term of the loans using methods that approximate the level yield method. Interest income on loans is accrued based on the unpaid principal balance outstanding and the contractual terms of the loan agreements. A substantial portion of the loan portfolio is comprised of commercial and real estate loans throughout Pennsylvania. The ability of the Corporation’s debtors to honor their contracts is dependent upon the general economic conditions of this area. The loan portfolio is segmented into commercial and industrial loans, commercial real estate loans, commercial real estate – construction loans, residential mortgage loans, home equity loans and consumer loans. Commercial and industrial loans are underwritten after evaluating and understanding the borrower’s ability to repay the loan through operating profitably and effectively growing its business. The Corporation’s management examines current and projected cash flows to determine the ability of the borrower to repay their obligations as agreed. Commercial loans are primarily made based on the credit quality and cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee to add strength to the credit and reduce the risk on a transaction to an acceptable level; however, some short-term loans may be made on an unsecured basis to the most credit worthy borrowers. Commercial loans also include loans originated under the Paycheck Protection Program ("PPP"). These loans are underwritten and originated in accordance with program guidelines. Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. With respect to loans to developers and builders, the Corporation generally requires the borrower to have a proven record of success and an expertise in the building industry. Commercial real estate - construction loans are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analysis of absorption and lease rates and financial analysis of the developers and property owners. Commercial real estate - construction loans are generally based upon estimates of costs and value associated with the complete project. These estimates may be inaccurate. Commercial real estate - construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. The Corporation’s non-real estate consumer loans are based on the borrower’s proven earning capacity over the term of the loan. The Corporation monitors payment performance periodically for consumer loans to identify any deterioration in the borrower’s financial strength. To monitor and manage consumer loan risk, policies and procedures are developed and modified, as needed, jointly by management and staff. This activity, coupled with a relatively small volume of consumer loans, minimizes risk. Acquired Loans - At the purchase or acquisition date, loans are evaluated to determine whether there has been more than insignificant credit deterioration since origination. Loans that have experienced more than insignificant credit deterioration since origination are referred to as PCD loans. In its evaluation of whether a loan has experienced more than insignificant deterioration in credit quality since origination, Mid Penn takes into consideration loan grades, past due and nonaccrual status. Mid Penn may also consider external credit rating agency ratings for borrowers and for non-commercial loans, FICO score or band, probability of default levels, and number of times past due. At the purchase or acquisition date, the amortized cost basis of PCD loans is equal to the purchase price and an initial estimate of credit losses. The initial recognition of expected credit losses on PCD loans has no impact on net income. When the initial measurement of expected credit losses on PCD loans is calculated on a pooled loan basis, the expected credit losses are allocated to each loan within the pool. Any difference between the initial amortized cost basis and the unpaid principal balance of the loan represents a noncredit discount or premium, which is accreted (or amortized) into interest income over the life of the loan. Subsequent changes to the ACL on PCD loans are recorded through the PCL. For purchased loans that are not deemed to have experienced more than insignificant credit deterioration since origination and are therefore not deemed PCD, any discounts or premiums included in the purchase price are accreted (or amortized) over the contractual life of the individual loan. Loans are charged off against the ACL, with any subsequent recoveries credited back to the ACL account. Expected recoveries may not exceed the aggregate of amounts previously charged off and expected to be charged off. The balance of loans acquired included in the balance of loans, net of unearned interest, on the Consolidated Balance Sheets totaled $324.5 million and $768.5 million as of December 31, 2023 and December 31, 2022, respectively. Non-accrual Loans - The Corporation classifies loans as past due when the payment of principal or interest is greater than 30 days delinquent based on the contractual next payment due date. The Corporation’s policies related to when loans are placed on non-accrual status conform to guidelines prescribed by regulatory authorities. Loans are placed on non-accrual status when it is probable that principal or interest is not fully collectible, or generally when principal or interest becomes 90 days past due, whichever occurs first. When loans are placed on non-accrual status, interest receivable is reversed against interest income in the current period and amortization of any discount ceases. Interest payments received thereafter are applied as a reduction to the remaining principal balance unless management believes that the ultimate collection of the principal is likely, in which case payments are recognized in earnings on a cash basis. Loans are removed from non-accrual status when they become current as to both principal and interest and the collectability of principal and interest is no longer doubtful. Generally, a non-accrual loan that is restructured remains on non-accrual for a reasonable period of time (generally, at least six consecutive months) to demonstrate the borrower can meet the restructured terms. However, performance prior to the restructuring, or significant events that coincide with the restructuring, are considered in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status after a shorter performance period. If the borrower’s ability to meet the revised payment schedule is not reasonably assured, the loan remains classified as a non-accrual loan. Modifications to Borrowers Experiencing Financial Difficulty - From time to time, we may modify certain loans to borrowers who are experiencing financial difficulty. In some cases, these modifications may result in new loans. Loan modifications to borrowers experiencing financial difficulty may be in the form of principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay, or a term extension, or a combination thereof, among other things. Allowance for Credit Losses, effective January 1, 2023 - Mid Penn’s ACL - loans methodology is based upon guidance within FASB ASC Subtopic 326-20, as well as regulatory guidance from the FDIC, its primary federal regulator. The ACL - loans is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. Credit quality within the loan portfolio is continuously monitored by management and is reflected within the ACL - loans. The ACL - loans is an estimate of expected losses inherent within Mid Penn’s existing loan portfolio. The ACL - loans is adjusted through the PCL 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 Mid Penn’s loan portfolio segments. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Evaluations of the portfolio and individual credits are inherently subjective, as they require estimates, assumptions and judgments as to the facts and circumstances of particular situations. Determining the appropriateness of the allowance is complex and requires judgement 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 ACL and credit loss expense. Mid Penn estimates the ACL using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Mid Penn uses a third-party software application to calculate the quantitative portion of the ACL using a methodology and assumptions specific to each loan pool. The qualitative portion of the allowance is based on general economic conditions and other internal and external factors affecting Mid Penn as a whole, as well as specific loans. Factors considered include the following: lending process, concentrations of credit, and credit quality. The quantitative and qualitative portions of the allowance are added together to determine the total ACL, which reflects management’s expectations of future conditions based on reasonable and supportable forecasts. The methodology for estimating the amount of expected credit losses reported in the ACL has two basic components: a collective, or pooled, component for estimated expected credit losses for pools of loans that share similar risk characteristics, and 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. In estimating the ACL for the collective component, loans are segregated into loan pools based on loan purpose codes and similar risk characteristics. The commercial real estate and residential mortgage loan portfolio segments include loans for both commercial and residential properties that are secured by real estate. The underwriting process for these loans includes analysis of the financial position and strength of both the borrower and, if applicable, guarantor, experience with similar projects in the past, market demand and prospects for successful completion of the proposed project within the established budget and schedule, values of underlying collateral, availability of permanent financing, maximum loan-to-value ratios, minimum equity requirements, acceptable amortization periods and minimum debt service coverage requirements, based on property type. The borrower’s financial strength and capacity to repay their obligations remain the primary focus of underwriting. Financial strength is evaluated based upon analytical tools that consider historical and projected cash flows and performance, in addition to analysis of the proposed project for income-producing properties. Additional support offered by guarantors is also considered when applicable. Ultimate repayment of these loans is sensitive to interest rate changes, general economic conditions, liquidity and availability of long-term financing. The commercial and industrial loan portfolio segment includes commercial loans made to many types of businesses for various purposes, such as short-term working capital loans that are usually secured by accounts receivable and inventory, equipment and fixed asset purchases that are secured by those assets, and term financing for those within Mid Penn’s geographic markets. Mid Penn’s credit underwriting process for commercial and industrial loans includes analysis of historical and projected cash flows and performance, evaluation of financial strength of both borrowers and guarantors as reflected in current and detailed financial information, and evaluation of underlying collateral to support the credit. The consumer loan portfolio segment is comprised of loans which are underwritten after evaluating a borrower’s capacity, credit and collateral. Several factors are considered when assessing a borrower’s capacity, including the borrower’s employment, income, current debt, assets and level of equity in the property. Credit is assessed using a credit report that provides credit scores and the borrower’s current and past information about their credit history. Loan-to-value and debt-to-income ratios, loan amount and lien position are also considered in assessing whether to originate a loan. These borrowers are particularly susceptible to downturns in economic trends, such as conditions that negatively affect housing prices and demand and levels of unemployment. Mid Penn utilizes a DCF method to estimate the quantitative portion of the allowance for credit losses for loan pools. The DCF is based off of historical losses, including peer data, which is correlated to national unemployment and GDP. The PD and LGD measures are used in conjunction with prepayment data as inputs into the DCF model to calculate the cash flows at the individual loan level. Contractual cash flows based on loan terms are adjusted for PD, LGD and prepayments to derive loss cash flows. These loss cash flows are discounted by the loan’s coupon rate to arrive at the discounted cash flow based quantitative loss. The prepayment studies are updated quarterly by a third-party for each applicable pool. Mid Penn determined that reasonable and supportable forecasts could be made for a twelve-month period for all of its loan pools. To the extent the lives of the loans in the LHFI portfolio extend beyond this forecast period, Mid Penn uses a reversion period of four quarters and reverts to the historical mean on a straight-line basis over the remaining life of the loans. Qualitative factors used in the ACL methodology include the following: •Lending process •Concentrations of credit •Peer Group Divergence The ACL for individual loans, such as non-accrual and PCD, that do not share risk characteristics with other loans is measured as the difference between the discounted value of expected future cash flows, based on the effective interest rate at origination, and the amortized cost basis of the loan, or the net realizable value. The ACL is the difference between the loan’s net realizable value and its amortized cost basis (net of previous charge-offs and deferred loan fees and costs), except for collateral-dependent loans. A loan is collateral dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the sale of the collateral. The expected credit loss for collateral-dependent loans is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, adjusted for the estimated cost to sell. Fair value estimates for collateral-dependent loans are derived from appraised values based on the current market value or the "as is" value of the collateral, normally from recently received and reviewed appraisals. Current appraisals are ordered on a regular basis based on the inspection date or more often if market conditions necessitate. Appraisals are obtained from state-certified appraisers and are based on certain assumptions, which may include construction or development status and the highest and best use of the property. These appraisals are reviewed by Mid Penn’s Appraisal Review Department to ensure they are acceptable, and values are adjusted down for costs associated with asset disposal. If the calculated expected credit loss is determined to be permanent or not recoverable, the amount of the expected credit loss is charged off. Mid Penn may also purchase loans or acquire loans through a business combination. At the purchase or acquisition date, loans are evaluated to determine whether there has been more than insignificant credit deterioration since origination. Loans that have experienced more than insignificant credit deterioration since origination are referred to as PCD loans. In its evaluation of whether a loan has experienced more than insignificant deterioration in credit quality since origination, Mid Penn takes into consideration loan grades, past due and nonaccrual status. Mid Penn may also consider external credit rating agency ratings for borrowers and for non-commercial loans, FICO score or band, probability of default levels, and number of times past due. At the purchase or acquisition date, the amortized cost basis of PCD loans is equal to the purchase price and an initial estimate of credit losses. The initial recognition of expected credit losses on PCD loans has no impact on net income. When the initial measurement of expected credit losses on PCD loans is calculated on a pooled loan basis, the expected credit losses are allocated to each loan within the pool. Any difference between the initial amortized cost basis and the unpaid principal balance of the loan represents a noncredit discount or premium, which is accreted (or amortized) into interest income over the life of the loan. Subsequent changes to the ACL on PCD loans are recorded through the PCL. For purchased loans that are not deemed to have experienced more than insignificant credit deterioration since origination and are therefore not deemed PCD, any discounts or premiums included in the purchase price are accreted (or amortized) over the contractual life of the individual loan. Loans are charged off against the ACL, with any subsequent recoveries credited back to the ACL account. Expected recoveries may not exceed the aggregate of amounts previously charged off and expected to be charged off. Allowance for Loan Losses - Prior to January 1, 2023 - The allowance for credit losses consists of the allowance for loan losses ("allowance"), and the reserve for unfunded lending commitments. The allowance represents management’s estimate of losses inherent in the loan portfolio as of the balance sheet date and is recorded as a reduction to loans. The reserve for unfunded lending commitments represents management’s estimate of losses inherent in its unfunded loan commitments and is recorded in other liabilities on the Consolidated Balance Sheet. The allowance is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectible are charged off to the allowance, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. Non-residential consumer loans are generally charged off no later than 120 days past due on a contractual basis, or earlier in the event of bankruptcy or if there is an amount deemed uncollectible. Because all identified losses are immediately charged off, no portion of the allowance for loan losses is restricted to any individual loan or groups of loans, and the entire allowance is available to absorb any and all loan losses. The allowance is maintained at a level considered by management to be adequate to provide for losses that can be reasonably anticipated. Management performs a monthly evaluation of the adequacy of the allowance. The allowance is based on Mid Penn’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions, and other relevant factors. This evaluation is inherently subjective, as it requires material estimates that may be susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired. For loans that are classified as impaired, an allowance is established when the discounted cash flows, collateral value, or observable market price of the impaired loan is lower than the carrying value of that loan. The general component covers pools of loans by loan class including commercial loans not considered impaired, as well as smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these categories of loans, adjusted for qualitative factors. These qualitative risk factors include changes in economic conditions, fluctuations in loan quality measures, changes in collateral values, changes in the experience of the lending staff and loan review systems, changes in lending policies and procedures (including underwriting standards), changes in the mix and volume of loans originated, the effect of other external factors, such as competition and legal and regulatory requirements on the level of estimated credit losses in the existing loan portfolio, shifting industry or portfolio concentrations, and other relevant factors. Each factor is assigned a value to reflect improving, stable or declining conditions based on management’s best judgment using relevant information available at the time of the evaluation. Adjustments to the factors are supported through documentation of changes in conditions and a narrative accompanying the allowance for loan loss calculation. Mid Penn evaluates loans for charge-off on a monthly basis. Policies that govern the recommendation for charge-off are unique to the type of loan being considered. Commercial loans classified as substandard non-accrual, doubtful, having probable loss will first have a collateral evaluation completed in accordance with the guidance on impaired loans. Once the collateral evaluation has been completed, a specific allocation of allowance is made based upon the results of the evaluation. The remaining balance remains a non-performing loan with the original terms and interest rate intact (not restructured). In the event the loan is unsecured, the loan would have been charged-off at the recognition of impairment. Commercial real estate loans determined to be impaired will also have an initial collateral evaluation completed in accordance with the guidance on impaired loans. An updated real estate valuation is ordered and the collateral evaluation is modified to reflect any variations in value. A specific allocation of allowance is made for any anticipated collateral shortfall. The remaining balance remains a non-performing loan with the original terms and interest rate intact (not restructured). The process of charging off a residential mortgage loan begins when a loan becomes delinquent for 90 days and is not in the process of collection. The existing appraisal is reviewed and a lien search is obtained to determine lien position and any instances of intervening liens. A new appraisal of the property will be ordered if deemed necessary by management, and a collateral evaluation is completed. The loan will then be charged down to the value indicated in the evaluation. Non-residential consumer loans are generally charged off no later than 120 days past due on a contractual basis, or earlier in the event of either bankruptcy or if there is an amount deemed uncollectible. The collateral shortfall of the consumer loan is recommended for charge-off at this point. As noted above, Mid Penn assesses a specific allocation for commercial loans and commercial real estate loans. The remaining balance remains a non-performing loan with the original terms and interest rate intact (not restructured). In addition, Mid Penn takes a preemptive step when any commercial loan becomes classified under its internal classification system. A preliminary collateral evaluation, in accordance with the guidance on impaired loans, is prepared using the existing collateral information in the loan file. This process allows Mid Penn to review both the credit and documentation files to determine the status of the information needed to make a collateral evaluation. This collateral evaluation is preliminary, but allows Mid Penn to determine if any potential collateral shortfalls exist. It is Mid Penn’s policy to obtain updated third-party collateral valuations on all impaired loans secured by real estate as soon as practically possible following the credit being classified as substandard non-accrual. Prior to receipt of the updated real estate valuation, Mid Penn will use any existing real estate valuation to determine any potential allowance issues; however, no allowance recommendation will be made until such time Mid Penn is in receipt of the updated valuation. The Asset Recovery department employs an electronic tracking system to monitor the receipt of and need for updated appraisals. To date, there have been no material time lapses noted with the above processes. In some instances, Mid Penn is not holding real estate as collateral and is relying on business assets (personal property) for repayment. In these circumstances, a collateral inspection is performed by Mid Penn personnel to determine an estimated value. The value is based on net book value, as provided by the financial statements, and discounted accordingly based on determinations made by management. Occasionally, Mid Penn will employ an outside service to provide a fair estimate of value based on auction sales or private sales. Management reviews the estimates of these third parties and discounts them accordingly based on management’s judgment, if deemed necessary. For impaired loans with no valuation allowance required, the independent third-party market valuations on the subject property obtained by Mid Penn as soon as practically possible following the credit being placed on non-accrual status sometimes indicates that the loan-to-value ratio is sufficient to obviate the need for a specific allocation in spite of significant deterioration in real estate values in Mid Penn’s primary market area. These circumstances are determined on a case-by-case analysis of the impaired loans. Mid Penn actively monitors the values of collateral on impaired loans. This monitoring may require the modification of collateral values over time or changing circumstances by some factor, either positive or negative, from the original values. All collateral values will be assessed by management at least every twelve months for revaluation by an independent third party. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, Mid Penn does not separately identify individual residential mortgage loans, home equity loans and other consumer loans for impairment disclosures, unless such loans are the subject of a troubled debt restructuring agreement. The allowance calculation methodology includes segregation of loan classes into risk rating categories. The borrower’s overall financial condition, repayment sources, guarantors, and value of collateral, if appropriate, are evaluated annually for commercial loans or when credit deficiencies arise, such as delinquent loan payments. Credit quality risk ratings include regulatory classifications of special mention, substandard, doubtful, and loss. Loans criticized as special mention have potential weaknesses that deserve management’s close attention. If uncorrected, the potential weaknesses may result in deterioration of the repayment prospects. Loans classified substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They include loans that are inadequately protected by the current sound net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified doubtful have all the weaknesses inherent in loans classified substandard with the added characteristic that collection or liquidation in full, on the basis of current conditions and facts, is highly improbable. Loans classified as a loss are considered uncollectible and are charged to the allowance for loan losses. Any loans not classified as noted above are rated pass. In addition, federal and state regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance and may require the Bank to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to management. Based on management’s comprehensive analysis of the loan portfolio, management believes the current level of the allowance for loan losses is adequate. Premises and Equipment - Land is carried at cost. Buildings, furniture, fixtures, equipment, land improvements, and leasehold improvements are stated at cost less accumulated depreciation. Depreciation is computed by the straight-line method over the estimated useful lives of the assets. Building assets are depreciated using an estimated useful life of five to fifty years. Furniture, fixtures, and equipment are depreciated using an estimated useful life of three to ten years. Land improvements are depreciated over an estimated useful life of ten to twenty years. Leasehold improvements are depreciated using an estimated useful life that is the lesser of the remaining life of the lease or ten to fifteen years. Maintenance and normal repairs are charged to expense when incurred, while major additions and improvements are capitalized. Gains and losses on disposals are reflected in current operations. The Corporation reviews the carrying value of long-lived assets and certain identifiable intangibles for impairment whenever events and changes in circumstances indicate that the carrying amount of an asset may not be recoverable, as prescribed by ASC Topic 360, "Accounting for the Impairment or Disposal of Long-Lived Assets". Bank Premises and Equipment Held For Sale - Bank premises and equipment designated as held for sale are included in Other Assets on the Balance Sheet, and are carried at the lower of cost or market value, and totaled $974 thousand and $1.3 million at December 31, 2023 and 2022, respectively. The balance at December 31, 2022 related to the December 7, 2021 announcement of a Retail Network Optimization Plan pursuant to which the Bank announced its intention to close certain retail locations throughout its expanded footprint. The branch closures occurred on about March 4, 2022. As of December 31, 2023, two properties remained for sale. Foreclosed Assets Held for Sale - Real estate properties acquired through, or in lieu of, loan foreclosure are initially recorded at their fair value less estimated disposition costs. When such assets are acquired, any shortfall between the loan carrying value and the estimated fair value of the underlying collateral less disposition costs is recorded as an adjustment to the allowance for loan losses while any excess is recognized in income. The Corporation periodically performs a valuation of the property held; any excess of carrying value over fair value less disposition costs is charged to earnings as impairment. Routine maintenance and real estate taxes are expensed as incurred. Bank-Owned Life Insurance ("BOLI") - Mid Penn is the owner and beneficiary of BOLI policies on current and former Mid Penn directors, as well as BOLI policies acquired through the Phoenix, First Priority and Riverview acquisitions covering certain former Miners Bank, First Priority, and Riverview employees. These policies are recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement, if applicable. Increases in the cash surrender value of these policies are included in noninterest income in the Consolidated Statements of Income. The Corporation's BOLI policies are invested in general account and hybrid account products that have been underwritten by highly-rated third party insurance carriers. Mid Penn is also party to certain Split-Dollar Life Insurance Arrangements, and in accordance with GAAP, has accrued a liability related to the postretirement benefits covered by an endorsement split-dollar life insurance arrangement, and a liability for the future death benefit. Goodwill and Other Intangible Assets - Goodwill represents the excess of the purchase price over the underlying fair value of merged entities. We assess goodwill for impairment annually as of October 31 of each year. The Corporation has one reporting unit, community banking, which includes the Bank, the Corporation’s wholly-owned banking subsidiary. If certain events occur which indicate goodwill might be impaired between annual tests, goodwill must be tested when such events occur. In making this assessment, we consider a number of factors including operating results, business plans, economic projections, anticipated future cash flows, current market data, etc. There are inherent uncertainties related to these factors and our judgment in applying them to the analysis of goodwill impairment. Changes in economic and operating conditions could result in goodwill impairment in future periods. The Bank did not identify any impairment on its outstanding goodwill from its most recent testing, which was perform ed as of October 31, 2023. Core deposit intangible ("CDI") is a measure of the value of checking and savings deposits acquired in business combinations. The fair value of the CDI stemming from any given business combination is based on the present value of the expected cost savings attributable to the core deposit funding relative to an alternative source of funding. CDI is amortized over the estimated useful lives of the existing deposit relationships acquired, but does not exceed ten years. Significantly all CDI is amortized using the sum of the years digits method. Customer list intangibles are a measure of the inherent value of certain customer arrangements acquired in business combinations. The fair value of the customer list is based on the income approach which employs a present value analysis, which calculates the expected after-tax cash flow benefits of the net revenues generated by the acquired customers over the expected life of the acquired customers, discounted at a long-term market-oriented after-tax rate of return on investment. The value assigned to the acquired customers represents the future economic benefit from acquiring the customers (net of operating expenses). The customer list is amortized over a 20-year projection period, a sufficient time to capture the economic value of the customer list given an assumed customer attrition rate. The Corporation evaluates such identifiable intangibles for impairment when events and circumstances indicate that its carrying amount may not be recoverable. If an impairment loss is determined to exist, the loss is reflected as an impairment charge in the Consolidated Statements of Income for the period in which such impairment is identified. No impairment charges were required for the years ended December 31, 2023, 2022, or 2021. Leases - Mid Penn leases certain premises and equipment and recognizes a right-of-use ("ROU") asset and a related lease liability for each distinct lease agreement. The lease ROU asset consists of the amount of the initial measurement of the lease liability, adjusted for any lease payments made to the lessor at or before the commencement date, minus any lease incentives received, and any initial direct costs incurred by the lessee (defined as costs of a lease that would not have been incurred had the lease not been executed). The related lease liability is equal to the present value of the future lease payments, discounted using the rate implicit in the lease (or if that rate cannot be readily determined, the lessee’s incremental borrowing rate). Given that the rate implicit in the lease is rarely available, all lease liability amounts are calculated using Mid Penn’s incremental borrowing rate at lease inception, on a collateralized basis, for a similar term. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. Operating and finance lease ROU assets, as well as operating lease liabilities, are presented as separate line items on the Consolidated Balance Sheet, while finance lease liabilities are classified as a component of long-term debt. Operating lease expense, recognized as a component of occupancy expense on the Consolidated Statements of Income, consists of a single lease cost calculated so that the remaining cost of the lease is allocated over the remaining lease term on a straight-line basis. Operating lease expense also includes variable lease payments not included in the lease liability, and any impairment of the ROU asset. Finance lease expense consists of the amortization of the ROU asset, recognized as a component of occupancy expense and interest expense on the lease liability, which is recorded as a component of other interest expense, both on the Consolidated Statements of Income. In assessing whether a contract contains a lease, Mid Penn reviews third-party agreements to determine if the contract conveys the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration, and grants Mid Penn the right to both obtain substantially all of the economic benefits from the identified asset’s use and the direct the use of the identified asset throughout the term of the agreement. Upon identification that a lease agreement exists, Mid Penn performs an assessment of the consideration to be paid related to the identified asset and quantifies both the lease components, consisting of consideration paid to transfer a good or service to Mid Penn and non-lease components, consisting of consideration paid for distinct elements of the contract that are not related to securing the use of the leased asset, such as property taxes, common area maintenance, utilities, and insurance. Many of Mid Penn’s lease agreements include options to extend or renew contracts subsequent to the expiration of the initial lease term. Additionally, for leases that contain escalation clauses related to consumer or other price indices, Mid Penn includes the known lease payment amount as of the commencement date in the calculation of ROU assets and related lease liabilities. Subsequent increases in rental payments over the known amount at the commencement date due to increase in the indices will be expensed as incurred. None of Mid Penn’s lease agreements include residual value guarantees or material variable lease payments. Mid Penn does not have material restrictions or covenants imposed by leases that would impact Mid Penn’s ability to pay dividends or cause Mid Penn to incur additional financial obligations. Comprehensive Income - Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes changes in unrealized gains and losses on securities available for sale arising during the period and reclassification adjustments for realized gains and losses on securities available for sale included in net income. Mid Penn has an unfunded noncontributory defined benefit plan for directors and other postretirement benefit plans covering full-time employees. These plans utilize assumptions and methods to calculate the fair value of plan assets and recognizing the overfunded and underfunded status of the plans on its Consolidated Balance Sheet. Gains and losses, prior service costs and credits are recognized in other comprehensive income (loss), net of tax, until they are amortized, or immediately upon curtailment. Trust Assets and Income - Assets held by the Bank in a fiduciary or agency capacity for customers of the trust department of the Bank are not included in the Consolidated Financial Statements since such items are not assets of the Bank. Most trust income is recognized on the cash basis, which is not materially different than if it were reported on the accrual basis. Revenue Recognition - Mid Penn recognizes revenue when earned based upon contractual terms, as transactions occur, or as related services are provided and collectability is reasonably assured. The largest source of revenue for Mid Penn is interest income. Noninterest income is earned from various banking and financial services that Mid Penn offers through its subsidiaries. In certain circumstances, noninterest income is reported net of associated expenses. Following is further detail on the various types of noninterest income Mid Penn earns and when it recognized: Interest Income - primarily recognized on an accrual basis according to loan agreements, investment securities contracts or other such written contracts. Income from Fiduciary and Wealth Management Activities - consists of trust, wealth management, and investment management fee income, brokerage transaction fee income, and estate fee income. Trust, wealth management, and investment management fee income consists of advisory fees that are typically based on market values of clients’ managed portfolios and transaction fees for fiduciary services performed, both of which are recognized as earned. Brokerage transaction fee income includes advisory fees, which are recognized as earned on a monthly basis and transaction fees that are recognized when transactions occur. Payment is typically received in the following month. Estate fee income is recognized as services are performed over the service period, generally eighteen months. ATM Debit Card Interchange Income - consists interchange fees earned when Mid Penn’s debit cards are processed through card payments networks. The interchange fee is calculated as a percentage of the total electronic funds transfer ("EFT") transaction plus a per-transaction fee, which varies based on the type of card used, the method used to process the EFT transaction, and the type of business at which the transaction was processed. Revenue is recognized daily as transactions occur and interchange fees are subsequently processed. Payment for interchange activity is received primarily daily, while some fees are aggregated and payment is received in the following month. Service Charges on Deposits - consist of cash management, overdraft, non-sufficient fund fees and other service charges on deposit accounts. Revenue is primarily transactional and recognized when earned, which is at the time the respective initiating transaction occurs and the related service charge is subsequently processed. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to the customers’ accounts. Mortgage Banking Income - consists of gains or losses on the sale of residential mortgage loans and is recognized when the sale is completed. Mortgage Hedging Income - relates to the changes in fair value of interest rate locks, forward mortgage loan sales commitments and hedging instruments on forward sales commitments. Other Income - includes credit card royalties, check orders, letter of credit fees and merchant services income. These fees are primarily transactional, and revenue is recognized when transactions occur and the related services are subsequently processed. Payment is primarily received immediately or in the following month. Mid Penn does not exercise significant judgements in the recognition of income, as typically income is not recognized until the performance obligation has been satisfied. Income Taxes - Income tax expense is determined using the asset and liability method and consists of income taxes that are currently payable and deferred income taxes. Deferred income tax expense (benefit) is determined by recognizing deferred tax assets and liabilities for future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates that are expected to apply to taxable income in years in which those temporary differences are expected to be recovered or settled. Changes in tax rates on deferred tax assets and liabilities are recognized in income in the period that includes the enactment date. A valuation allowance is established for deferred tax assets when management determines that it is more likely than not that some portion or all of a deferred tax asset will not be realized. In making such determinations, the Corporation considers all available positive and negative evidence that may impact the realization of deferred tax assets. These considerations include future reversals of existing taxable temporary differences, projected future taxable income, and available tax planning strategies. The Corporation files a consolidated federal income tax return including the results of its wholly-owned subsidiaries. The Corporation estimates income taxes payable based on the amount it expects to owe the various tax authorities (i.e., federal and state). Income taxes represent the net estimated amount due to, or to be received from, such tax authorities. In estimating income taxes, management assesses the relative merits and risks of the appropriate tax treatment of transactions, taking into account statutory, judicial, and regulatory guidance in the context of the Corporation’s tax position. Although the Corporation uses the best available information to record income taxes, underlying estimates and assumptions can change over time as a result of unanticipated events or circumstances such as changes in tax laws and judicial guidance influencing its overall tax position. An uncertain tax position is recognized only if it is more-likely-than-not to be sustained upon examination, including resolution of any related appeals or litigation process, based on the technical merits of the position. The amount of tax benefit recognized in the financial statements is the largest amount of benefit that is more than fifty percent likely to be sustained upon ultimate settlement of the uncertain tax position. If the initial assessment fails to result in recognition of a tax benefit, the Corporation subsequently recognizes a tax benefit if there are changes in tax law or case law that raise the likelihood of prevailing on the technical merits of the position to more-likely-than-not, the statute of limitations expires, or there is a completion of an examination resulting in a settlement of that tax year or position with the appropriate agency. The Corporation’s policy is to classify interest and penalties associated with income taxes within other expenses. The Corporation is subject to routine audits by taxing jurisdictions; however, there are currently no audits in progress for any tax periods. Management believes it is no longer subject to income tax examinations for years prior to 2020. Off-Balance Sheet Arrangements - The Corporation enters into contractual loan commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Since a portion of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Substantially all of the commitments to extend credit are contingent upon customers maintaining specific credit standards until the time of loan funding. The Corporation decreases its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures. Standby letters of credit are written conditional commitments issued by the Corporation to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Corporation would be required to fund the commitment. The maximum potential amount of future payments the Corporation could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, the Corporation would be entitled to seek recovery from the customer. The Corporation’s policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements. Earnings per Common Share - The Corporation presents basic and diluted earnings per common share ("EPS") data for its common stock. Basic EPS is calculated by dividing the net income attributable to shareholders of the Corporation by the weighted average number of shares of common stock outstanding during the period. Diluted EPS is determined by adjusting the profit or loss attributable to shareholders and the weighted average number of shares of common stock outstanding adjusted for the effects of all dilutive potential common shares comprised of restricted stock awards. Treasury Stock - Common stock held in treasury is accounted for using the cost method, which treats stock held in treasury as a reduction to total stockholders’ equity. The shares may be purchased in the open market or in privately negotiated transactions from time to time depending upon the market conditions and other factors over a one-year period or such longer period of time as may be necessary to complete such repurchases. Derivative Financial Instruments Loan-level Interest Rate Swaps The Corporation offers certain derivative products directly to qualified commercial lending clients seeking to manage their interest rate risk. The Corporation economically hedges interest rate swap transactions to execute with commercial lending clients by entering into offsetting interest rate swap transactions with institutional derivatives market participants. Derivative transactions executed as part of this program are not designed as qualifying hedging relationships and are, therefore, carried at fair value with the change in fair value recorded as noninterest income. Because these derivatives have mirror-image contractual terms, in additional to collateral provisions which mitigate the impact of non-performance risk, the changes in fair value are expected to substantially offset. Cash Flow Hedges of Interest Rate Risk Mid Penn’s objectives in using interest rate derivatives are to reduce volatility in net interest income and to manage its exposure to interest rate movements. To accomplish this objective, Mid Penn primarily uses interest rate swaps as part of its interest rate risk management strategy. Beginning in the first quarter of 2023, Mid Penn entered into interest rate swaps designated as cash flow hedges to hedge the cash flows associated with existing brokered CDs. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the unrealized gain or loss on the derivative is recorded in AOCI and subsequently reclassified into interest income in the same period during which the hedged transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest income as interest payments are made on Mid Penn’s variable-rate liabilities. Mortgage Banking Derivative Financial Instruments In connection with its mortgage banking activities, Mid Penn entered into commitments to originate certain fixed-rate residential mortgage loans for customers, also referred to as interest rate locks. In addition, Mid Penn entered into forward commitments for the future sales or purchases of mortgage-backed securities to or from third-party counterparties to hedge the effect of changes in interest rates on the values of both the interest rate locks and mortgage loans held for sale. Forward sales commitments may have also be in the form of commitments to sell individual mortgage loans at a fixed price at a future date. The amount necessary to settle each interest rate lock was based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured. As of December 31, 2023. Mid Penn no longer participates in mortgage banking derivative activities. Recent Accounting Pronouncements Accounting Standards Adopted On January 1, 2023, the Corporation adopted ASU 2016-13, Financial Instruments - Credit Losses (ASC Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss methodology, and is referred to as CECL. The measurement of expected credit losses under CECL is applicable to financial assets measured at amortized cost, including loans and HTM debt securities. It also applies to OBS credit exposures (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with ASC Topic 842. The Corporation adopted CECL using the modified retrospective method for all financial assets measured at amortized cost, net of investments in leases and OBS credit exposures. Results for reporting periods beginning after January 1, 2023 are presented under CECL, while prior period results are reported in accordance with the previously applicable incurred loss methodology. The Corporation recorded an overall increase of $15.0 million to the ACL on January 1, 2023 as a result of the adoption of CECL. Retained earnings decreased $11.5 million and deferred tax assets increased by $3.1 million. Included in the $15.0 million increase to the ACL was $3.1 million for certain OBS credit exposures that were previously recognized in other liabilities before the adoption of CECL. On January 1, 2023, the Corporation adopted ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which eliminates the accounting guidance for troubled debt restructurings in Accounting Standards Codification ("ASC") Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, ASU 2022-02 requires entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC Subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. See "Note 4 - Loans and Allowance for Credit Losses - Loans" for the new financial statement disclosures applicable under this update. The updates to the significant accounting policies related to CECL are further discussed in "Note 3 - Investment Securities", "Note 4 - Loans and Allowance for Credit Losses - Loans" and "Note 8 - Commitments and Contingencies". Accounting Standards Pending Adoption ASU No. 2023-02: The FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. The amendments in this update permit reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. A reporting entity may make an accounting policy election to apply the proportional amortization method on a tax-credit-program-by-tax-credit-program basis rather than electing to apply the proportional amortization method at the reporting entity level or to individual investments. The amendments in this update also remove certain guidance for Qualified Affordable Housing Project investments and require the application of the delayed equity contribution guidance to all tax equity investments. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and must be applied on either a modified retrospective or a retrospective basis. Early adoption is permitted in any interim period, however if adopted in an interim period the entity shall adopt the amendments in this update as of the beginning of the fiscal year that includes the interim period. The Corporation does not expect the adoption of ASU No. 2023-02 to have a material impact on its consolidated financial statements. ASU 2023-06: The FASB issued ASU 2023-06, Disclosure Improvements - Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. ASU 2023-06 amends the ASC to incorporate certain disclosure requirements from SEC Release No. 33-10532 - Disclosure Update and Simplification that was issued in 2018. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. ASU 2023-06 is not expected to have a significant impact on our financial statements. ASU 2023-07: The FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ASU 2023-07 amends the ASC to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. ASU 2023-09: The FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures
