Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	(1) Basis of Presentation For all periods presented, the accompanying consolidated financial statements include the accounts of Mid Penn Bancorp, Inc. and its wholly-owned subsidiary, Mid Penn Bank (the “Bank”). Mid Penn Bancorp, Inc. and its wholly owned subsidiaries are collectively referred to herein as “Mid Penn” or the “Corporation.” All material intercompany accounts and transactions have been eliminated in consolidation. Each of Mid Penn’s lines of business are part of the same reporting segment, community banking, whose operating results are regularly reviewed and managed by a centralized executive management group. As a result, Mid Penn has only one reportable segment for financial reporting purposes. On January 8, 2018, Mid Penn completed its acquisition of The Scottdale Bank & Trust Company (“Scottdale”), a Pennsylvania bank and trust company, through the merger of Scottdale with and into Mid Penn Bank pursuant to the previously announced Agreement and Plan of Merger, dated as of March 29, 2017, among Mid Penn, Mid Penn Bank and Scottdale. Refer to Note 4, Acquisition of The Scottdale Bank & Trust Company On July 31, 2018, Mid Penn completed its acquisition of First Priority Financial Corp. (“First Priority”), pursuant to the previously announced Agreement and Plan of Merger dated as of January 16, 2018. On July 31, 2018, First Priority was merged with and into Mid Penn, with Mid Penn being the surviving corporation. Refer to Note 5, Acquisition of First Priority Financial Corp., The comparability of Mid Penn’s results of operations for the year ended December 31, 2019, compared to the years ended December 31, 2018 and 2017, in general, have been materially impacted by these two acquisitions, as further described in Note 4 and Note 5. For comparative purposes, the December 31, 2018 and December 31, 2017 balances have been reclassified, when necessary, to conform to the 2019 presentation. Such reclassifications had no impact on net income. 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, 2019, for items that should potentially be recognized or disclosed in these consolidated financial statements.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	3) Summary of Significant Accounting Policies The accounting and reporting policies of Mid Penn conform with accounting principles generally accepted in the United States of America (“GAAP”) and to general practice within the financial industry. The following is a description of the more significant accounting policies. (a) Use of Estimates The preparation of financial statements 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 financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan and lease losses, the assessment of other-than-temporary impairment of investment securities, the valuation of the goodwill for impairment, and the valuation of assets acquired and liabilities assumed in business combinations. (b) 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. (c) 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, 2019 and 2018, there was no cash reserve balances required to be maintained at the Federal Reserve of Philadelphia because the Bank had sufficient vault cash available. (d) Interest-bearing Time Deposits with Other Financial Institutions Interest-bearing time deposits with other financial institutions consist of certificates of deposits in other financial institutions with maturities within one year. (e) Investment Securities Securities to be held for indefinite periods, but not intended to be held to maturity, are classified as available for sale and carried at fair value. Securities held for indefinite periods include securities that management intends to use as part of its asset and liability management strategy and that may be sold in response to liquidity needs, changes in interest rates, resultant prepayment risk, pledging requirements, and other factors related to effective portfolio management. For available-for-sale debt securities, realized gains and losses on dispositions are based on the difference between net proceeds and the amortized cost of the securities sold, using the specific identification method. Unrealized gains and losses on debt securities are based on the difference between the amortized cost and fair value of each security as of the respective reporting date. Unrealized gains and losses are credited or charged to other comprehensive income, whereas realized gains and losses flow through Mid Penn’s consolidated statement of income for the respective period. Securities to be held to maturity are carried at amortized cost. Unrealized holding gains and losses on held-to-maturity securities are excluded from earnings, and are not a component of accumulated other comprehensive income (loss) within shareholders’ equity. Premiums and discounts on debt securities are amortized as an adjustment to interest income using the interest method. Realized gains and losses on sales of investment securities are computed on the basis of specific identification of the cost of each security. ASC Topic 320, Investments – Debt Securities In instances when a determination is made that other-than-temporary impairment exists but the Company does not intend to sell the debt security and it is not more likely than not that it will be required to sell the debt security prior to its anticipated recovery, this guidance changes the presentation and amount of the other-than-temporary impairment recognized in the income statement. The other-than-temporary impairment is separated into (a) the amount of the total other-than-temporary impairment related to a decrease in cash flows expected to be collected from the debt security (the credit loss) and (b) the amount of the total other-than-temporary impairment related to all other factors. The amount of the total other-than-temporary impairment related to the credit loss is recognized in earnings. The amount of the total other-than-temporary impairment related to all other factors is recognized in other comprehensive income. (f) Equity Securities As a result of the adoption of ASU 2016-01 , Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities As of December 31, 2019 and December 31, 2018, Mid Penn’s equity securities consisted of Community Reinvestment Act funds totaling $507,000 and $492,000, respectively. No equity securities were sold during the years ended December 31, 2019 and December 31, 2018. (g) Loans Held for Sale Mortgage loans originated and intended for sale in the secondary market are included in loans held for sale and are 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 the Consolidated Statements of Income in mortgage banking income. (h) Loans and Allowance for Loan and Lease Losses Loans receivable 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 an allowance for loan losses and any deferred fees or costs. Interest income is accrued on the unpaid principal balance. Residential loans held for sale are carried at fair value and are included in loans held for sale on the balance sheet. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the yield (interest income) of the related loans, generally being amortized 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. The loan portfolio is segmented into commercial and consumer loans. Commercial loans consist of the following classes: commercial and industrial, commercial real estate, commercial real estate-construction and lease financing. Consumer loans consist of the following classes: residential mortgage loans, home equity loans and other consumer loans. For all classes of loans, the accrual of interest generally is discontinued when the contractual payment of principal or interest has become 90 days or more past due, or management has serious doubts about further collectability of principal or interest even though the loan is currently performing. A loan past due 90 days or more may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest is credited to income. Interest received on nonaccrual loans, including impaired loans, is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Nonaccrual loans may be restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time (generally, at least nine consecutive months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The past due status of all classes of loans receivable is determined based on contractual due dates for loan payments. Commercial and industrial Mid Penn originates commercial and industrial loans. Most of the Bank’s commercial and industrial loans have been extended to finance local and regional businesses and include short-term loans to finance machinery and equipment purchases, inventory, and accounts receivable. Commercial loans also involve the extension of revolving credit for a combination of equipment acquisitions and working capital in expanding companies. The maximum term for loans extended on machinery and equipment is based on the projected useful life of such machinery and equipment. Generally, the maximum term on non-mortgage lines of credit is one year. The loan-to-value ratio on such loans and lines of credit generally may not exceed 80 percent of the value of the collateral securing the loan. The Bank’s commercial business lending policy includes credit file documentation and analysis of the borrower’s character, capacity to repay the loan, the adequacy of the borrower’s capital and collateral, as well as an evaluation of conditions affecting the borrower. Analysis of the borrower’s past, present, and future cash flows is also an important aspect of the Bank’s current credit analysis. Nonetheless, such loans are believed to carry higher credit risk than other extensions of credit. Commercial and industrial loans typically are made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial business loans may be substantially dependent on the success of the business itself, which, in turn, is likely to be dependent upon the general economic environment. Mid Penn’s commercial and industrial loans are usually, but not always, secured by business assets and personal guarantees. However, the collateral securing the loans may depreciate over time, may be difficult to appraise, and may fluctuate in value based on the success of the business. Commercial real estate and commercial real estate - construction Commercial real estate and commercial real estate construction loans generally present a higher level of risk than loans secured by one-to-four family residences. This greater risk is due to several factors, including the concentration of principal in a limited number of loans and borrowers, the effect of general economic conditions on income producing properties, and the increased difficulty of evaluating and monitoring these types of loans. In addition, the repayment of loans secured by commercial real estate is typically dependent upon the successful operation of the related real estate project. If the cash flow from the project is reduced, the borrower’s ability to repay the loan may be impaired. Residential mortgage Mid Penn offers a wide array of residential mortgage loans for both permanent structures and those under construction. The Bank’s residential mortgage originations are secured primarily by properties located in its primary market and surrounding areas. Residential mortgage loans have terms up to a maximum of 30 years and with loan-to-value ratios up to 100 percent of the lesser of the appraised value of the security property or the contract price. Private mortgage insurance is generally required in an amount sufficient to reduce the Bank’s exposure to at or below the 85 percent loan-to-value level. Residential mortgage loans generally do not include prepayment penalties. In underwriting residential mortgage loans, the Bank evaluates both the borrower’s ability to make monthly payments and the value of the property securing the loan. Most properties securing real estate loans made by Mid Penn are appraised by independent fee appraisers. The Bank generally requires borrowers to obtain title insurance and fire and property insurance (including flood insurance, if necessary) in an amount not less than the amount of the loan. Real estate loans originated by the Bank generally contain a “due on sale” clause allowing the Bank to declare the unpaid principal balance due and payable upon the sale of the security property. The Bank underwrites residential mortgage loans to the standards established by the secondary mortgage market, i.e., Fannie Mae, Ginnie Mae, Freddie Mac, Federal Home Loan Bank or Pennsylvania Housing Finance Agency standards, with the intention of selling the majority of residential mortgages originated into the secondary market. In the event that the facts and circumstances surrounding a residential mortgage application do not meet all underwriting conditions of the secondary mortgage market, the Bank will evaluate the failed conditions and evaluate the potential risk of holding the residential mortgage in the Bank’s portfolio rather than rejecting the loan request. In the event that the loan is funded and held in the Bank’s portfolio, the interest rate on the residential mortgage would be increased to compensate for the added portfolio risk. Consumer, including home equity Mid Penn offers a variety of secured consumer loans, including home equity, automobile, and deposit secured loans. In addition, the Bank offers other secured and unsecured consumer loans. Most consumer loans are originated in Mid Penn’s primary market and surrounding areas. The largest component of Mid Penn’s consumer loan portfolio consists of fixed rate home equity loans and variable rate home equity lines of credit. Substantially all home equity loans and lines of credit are secured by junior lien mortgages on principal residences. The Bank will lend amounts, which, together with all prior liens, typically may be up to 85 percent of the appraised value of the property securing the loan. Home equity term loans may have maximum terms up to 20 years, while home equity lines of credit generally have maximum terms of five years. Consumer loan terms vary according to the type and value of collateral, length of contract and creditworthiness of the borrower. The underwriting standards employed by the Bank for consumer loans include an application, a determination of the applicant’s payment history on other debts, and an assessment of ability to meet existing obligations and payments on the proposed loan. Although creditworthiness of the applicant is a primary consideration, the underwriting process also includes a comparison of the value of the collateral, if any, in relation to the proposed loan amount. Consumer loans may entail greater credit risk than do residential mortgage loans, particularly in the case of consumer loans which are unsecured or are secured by rapidly depreciable assets, such as automobiles or recreational equipment. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be affected by adverse personal circumstances. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount that can be recovered on such loans. Junior liens inherently have more credit risk by virtue of the fact that another financial institution may have a higher security position in the case of foreclosure liquidation of collateral to extinguish the debt. Generally, foreclosure actions could become more prevalent if the real estate market weakens and property values deteriorate. Allowance for Loan and Lease Losses The allowance for credit losses (“allowance”) consists of (i) the allowance for loan and lease losses, and (ii) the reserve for unfunded lending commitments. The allowance for loan and lease losses 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 reserve for unfunded lending commitments was $80,000 at December 31, 2019 and $159,000 at December 31, 2018. The allowance is increased by the provision for loan and lease 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 and lease 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. The unallocated component of the allowance for loan and lease losses covers several considerations that are not specifically measureable through either the specific and general components. For example, at times Mid Penn could face increasing credit risks and uncertainties, not yet reflected in recent historical losses or qualitative factor assessments, associated with unpredictable changes in economic growth or business conditions in our markets or for certain industries in which we have commercial loan borrowers, or unanticipated stresses to the values of real estate held as collateral. Any or all of these additional issues can adversely affect our borrowers’ ability to timely repay their loans. Additionally, we have experienced continued strong commercial loan growth, including growth in newer markets where we have less of a loss history. Also, the unallocated component allocation recognizes the inherent imprecision in our allowance for loan and lease loss methodology, or any alternative methodology, for estimating specific and general loan losses, including the unpredictable timing and amounts of charge-offs, the fact that historical loss averages don’t necessarily correlate to future loss trends, and unexpected changes to specific-credit or general portfolio future cash flows and collateral values which could negatively impact unimpaired portfolio loss factors. Mid Penn generally considers a commercial loan (consisting of commercial and industrial, commercial real estate, commercial real estate-construction, and lease financing loan classes) to be impaired when it becomes 90 days or more past due and not in the process of collection, or sooner when it is probable that Mid Penn will be unable to collect all contractual principal and interest due. This methodology assumes the borrower cannot or will not continue to make additional payments. At that time, the loan would generally be considered collateral dependent as the discounted cash flows method would generally indicate no operating income available for evaluating the collateral position; therefore, most impaired loans are deemed to be collateral dependent. In addition, Mid Penn’s rating system assumes any loans classified as nonaccrual, included in the substandard rating, to be impaired, and most of these loans are considered collateral dependent; therefore, most of Mid Penn’s impaired loans, whether reporting a specific allocation or not, are considered collateral dependent. 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 nonaccrual, 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 nonperforming 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 nonperforming 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 nonperforming 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 nonaccrual. 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 nonaccrual 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. Loans whose terms are modified are classified as troubled debt restructurings if the borrowers have been granted concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring generally involve a temporary reduction in interest rate or an extension of a loan’s stated maturity date. Nonaccrual troubled debt restructurings are restored to accrual status if principal and interest payments, under the modified terms, are current for nine consecutive months after modification. Loans classified as troubled debt restructurings are designated as impaired. 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. Acquired Loans Loans that Mid Penn acquires in connection with business combinations are recorded at fair value with no carryover of the existing related allowance for loan losses. Fair value of the loans involves estimating the amount and timing of principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Loans acquired with credit deterioration are accounted for under ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality Loans acquired through business combinations that meet the specific criteria of ASC 310-30 are individually evaluated each period to analyze expected cash flows. To the extent that the expected cash flows of a loan have decreased due to credit deterioration, Mid Penn establishes an allowance. Loans acquired through business combinations that do not meet the specific criteria of ASC 310-30 are accounted for under ASC 310-20. These loans are initially recorded at fair value, and include credit and interest rate marks associated with acquisition accounting adjustments. Purchase premiums or discounts are subsequently amortized as an adjustment to yield, using the level yield method, over the estimated contractual lives of the loans. There is no allowance for loan losses established at the acquisition date for acquired performing loans. An allowance for loan losses is recorded for any credit deterioration in these loans subsequent to acquisition. Acquired loans that met the criteria for impaired or nonaccrual of interest prior to the acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if Mid Penn expects to fully collect the new carrying value (i.e. fair value) of the loans. As such, Mid Penn may no longer consider the loan to be nonaccrual or nonperforming at the date of acquisition and may accrue interest on these loans, including the impact of any accretable discount. In addition, charge-offs on such loans would be first applied to the nonaccretable difference portion of the fair value adjustment. (i) Bank 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. (j) Bank Premises and Equipment Held For Sale Bank premises and equipment designated as held for sale are carried at the lower of cost or market value. There were no premises and equipment classified as held for sale as of December 31, 2019 or 2018. During 2019,

Acquisition

Acquisition	12 Months Ended

Scottdale Bank and Trust Company [Member]
Acquisition	(4) Acquisition of The Scottdale Bank and Trust Company On January 8, 2018, Scottdale merged with and into Mid Penn Bank, with Mid Penn Bank continuing as the surviving entity. Pursuant to the merger agreement, each share of Scottdale common stock issued and outstanding immediately prior to January 8, 2018 converted into the right to receive (i) $1,166 in cash without interest or (ii) 38.88 shares of Mid Penn common stock. As a result, Mid Penn issued 1,878,827 shares of Mid Penn common stock with an acquisition date fair value of approximately $64,181,000, based on the closing stock price of Mid Penn’s common stock on January 8, 2018 of $34.16, and cash of $2,792,000. Including an insignificant amount of cash paid in lieu of fractional shares, the fair value of total consideration paid was $66,973,000. The assets and liabilities of Scottdale were recorded on the consolidated balance sheet of the Company at their estimated fair value as of January 8, 2018, and their results of operations have been included in the consolidated income statement of the Company since such date. Scottdale has been fully integrated into Mid Penn; therefore, the amount of revenue and earnings of Scottdale included in the consolidated income statement since the acquisition date is impracticable to provide. Included in the purchase price was goodwill of $19,178,000 and a core deposit intangible of $4,940,000. The core deposit intangible will be amortized over a ten-year period using a sum of the years’ digits basis. The goodwill will not be amortized, but will be measured annually for impairment or more frequently if circumstances require. During the years ended December 31, 2019 and 2018, core deposit intangible amortization expense related to the Scottdale acquisition totaled $808,000 and $898,000, respectively. Core deposit intangible amortization related to the Scottdale acquisition for the five years beginning 2020 through 2024 is estimated to be $719,000, $629,000, $539,000, $449,000, and $359,000 per year, respectively, and $539,000 in total for the three years after 2024. The allocation of the purchase price is as follows: (Dollars in thousands) Assets acquired: Cash and cash equivalents $ 67,817 Investment securities 114,039 Restricted stock 97 Loans 70,769 Goodwill 19,178 Core deposit intangible 4,940 Premises and equipment 1,496 Foreclosed assets 11 Deferred income taxes 1,050 Accrued interest receivable 989 Other assets 266 Total assets acquired 280,652 Liabilities assumed: Deposits 209,981 Accrued interest payable 16 Other liabilities 3,682 Total liabilities assumed 213,679 Consideration paid $ 66,973 Cash paid $ 2,792 Fair value of common stock issued 64,181 The following table summarizes the final estimated fair value of the assets acquired and liabilities and equity assumed in the Scottdale transaction. (Dollars in thousands) Total purchase price (consideration paid) $ 66,973 Net assets acquired: Cash and cash equivalents 67,817 Investment securities 114,039 Restricted stock 97 Loans 70,769 Core deposit intangible 4,940 Premises and equipment 1,496 Foreclosed assets 11 Deferred income taxes 1,050 Accrued interest receivable 989 Other assets 266 Deposits (209,981 ) Accrued interest payable (16 ) Other liabilities (3,682 ) 47,795 Goodwill $ 19,178 In general, factors contributing to goodwill recognized as a result of the Scottdale acquisition include expected cost savings from combined operations, opportunities to expand into several new markets, and growth and profitability potential from the repositioning of short-term investments into higher-yielding loans. The goodwill acquired as a result of the Scottdale acquisition is not tax deductible. The fair value of the financial assets acquired included loans receivable with a net amortized cost basis of $70,769,000. The table below illustrates the fair value adjustments made to the amortized cost basis in order to present a fair value of the loans acquired. (Dollars in thousands) Gross amortized cost basis at January 8, 2018 $ 71,809 Market rate adjustment 601 Credit fair value adjustment on pools of homogeneous loans (995 ) Credit fair value adjustment on impaired loans (646 ) Fair value of purchased loans at January 8, 2018 $ 70,769 The market rate adjustment represents the movement in market interest rates, irrespective of credit adjustments, compared to the contractual rates of the acquired loans. The credit adjustment made on pools of homogeneous loans represents the changes in credit quality of the underlying borrowers from loan inception to the acquisition date. The credit adjustment on impaired loans is derived in accordance with ASC 310-30-30 and represents the portion of the loan balance that has been deemed uncollectible based on our expectations of future cash flows for each respective loan.

First Priority Financial Corp. [Member]
Acquisition	(5 ) Acquisition of First Priority Financial Corp. On July 31, 2018, Mid Penn completed its acquisition of First Priority, through the merger of First Priority with and into Mid Penn. In connection with this acquisition, First Priority Bank, First Priority’s wholly-owned bank subsidiary, was merged with and into Mid Penn Bank. Pursuant to the merger agreement between Mid Penn and First Priority, the common shareholders of First Priority received 0.3481 shares of Mid Penn common stock for each share of First Priority common stock owned. Additionally, outstanding options to purchase First Priority common stock at the time of the merger were converted into the right to receive cash at a per-option value of $11.07 less the applicable exercise price, without interest. As a result of the acquisition, Mid Penn’s fulfillment of the merger consideration requirements resulted in (i) the issuance of 2,320,800 shares of Mid Penn common stock with an acquisition date fair value of approximately $76,122,000 based on the closing stock price of Mid Penn’s common stock of $32.80 on July 31, 2018, (ii) the payment $3,801,000 related to cashing out the stock options, (iii) cash paid of $6,000 in lieu of fractional shares, and (iv) the issuance of The assets and liabilities of First Priority were recorded on the consolidated balance sheet of the Company at their estimated fair value as of July 31, 2018, and their results of operations have been included in the consolidated income statement of the Company since such date. First Priority has been fully integrated into Mid Penn; therefore, the amount of revenue and earnings of First Priority included in the consolidated income statement since the acquisition date is impracticable to provide. Included in the purchase price was $39,744,000 of goodwill, a core deposit intangible of $2,832,000, and a trade name intangible of $205,000. The core deposit intangible will be amortized over a ten-year period using a sum of the years’ digits basis. The goodwill will not be amortized, but will be measured annually for impairment or more frequently if circumstances require. Core deposit intangible amortization expense recognized in 2019 and 2018 related to the First Priority acquisition totaled $493,000 and $215,000, respectively. Core deposit intangible amortization expense related to the First Priority acquisition for the five years beginning 2020 through 2024 is estimated to be $442,000, $390,000, $339,000, $288,000 and $236,000 per year, respectively, and $429,000 in total for the four years after 2024.

The goodwill acquired as a result of the First Priority acquisition is not tax deductible. The fair value of the financial assets acquired included loans receivable with a net amortized cost basis of $511,623,000.

Consideration is given to the length of time and the extent to which the fair value has been less than cost, and the financial condition and near term prospects of the issuer. In addition, for debt securities, Mid Penn considers (a) whether management has the intent to sell the security, (b) it is more likely than not that management will be required to sell the security prior to its anticipated recovery, and (c) whether management expects to recover the entire amortized cost basis. For equity securities, management considers the intent and ability to hold securities until recovery of unrealized losses. At December 31, 2019, the majority of the unrealized losses on securities in an unrealized loss position were attributed to U.S. government agencies and mortgage-back U.S. government agencies. At December 31, 2018, the majority of the unrealized losses on securities in an unrealized loss position were attributed to state and political subdivision obligations, mortgage-back U.S. government agencies, and U.S. government agencies. Mid Penn had no securities considered by management to be other-than-temporarily impaired as of December 31, 2019 and December 31, 2018, and did not record any securities impairment charges in the respective periods ended on these dates. Mid Penn does not consider the securities with unrealized losses on the respective dates to be other-than-temporarily impaired as the unrealized losses were deemed to be temporary changes in value related to market movements in interest yields at various periods similar to the maturity dates of holdings in the investment portfolio, and not reflective of an erosion of credit quality.

The remaining $1,748,000 of troubled debt restructurings was attributable to eight loans among five relationships which were classified as nonaccrual impaired based upon a collateral evaluation in accordance with the guidance on impaired loans. One large relationship accounted for $1,252,000 of the total $1,748,000 in nonaccrual impaired troubled debt restructured loans. As of December 31, 2019, there were no defaulted troubled debt restructured loans, as all troubled debt restructured loans were current with respect to their associated forbearance agreements. There were also no defaults on troubled debt restructured loans within twelve months of restructure during 2019. Mid Penn’s troubled debt restructured loans at December 31, 2018 totaled $7,020,000, and included four loans totaling $517,000 representing accruing impaired loans to unrelated borrowers in compliance with the terms of the modifications, with three loans being accruing impaired residential mortgages to unrelated borrowers totaling $516,000 and one loan being an accruing impaired home equity loan of $1,000. The remaining $6,503,000 of troubled debt restructurings was attributable to ten loans among five relationships which were classified as nonaccrual impaired based upon a collateral evaluation in accordance with the guidance on impaired loans. Two large relationships accounted for $5,463,000 of the total $6,503,000 in nonaccrual impaired troubled debt restructured loans.

There were also no defaults on troubled debt restructured loans within twelve months of restructure during 2018. Mid Penn entered into forbearance agreements on all loans currently classified as troubled debt restructurings and all of these agreements have resulted in additional principal repayment. The terms of these forbearance agreements vary whereby principal payments have been decreased, interest rates have been reduced and/or the loan will be repaid as collateral is sold. There were two loans modified in 2019, one loan modified in 2018, and ten loans modified in 2017 that resulted in troubled debt restructurings.

Leases [Abstract]
Leases	(9) Leases On January 1, 2019, Mid Penn adopted ASU No. 2016-02, Leases In 2016, Mid Penn entered into two subleasing agreements with unrelated parties on one of its properties under an operating lease. Both subleases included escalation clauses. The first sublease agreement began on April 1, 2016, while the second sublease began on July 1, 2016. One sublease was terminated during the first quarter of 2019 due to the bankruptcy of the tenant. The remaining sublease ends on March 31, 2021. As a result of the adoption of ASU 2016-02, the remaining balance of a deferred sale/leaseback gain originated in 2017 was eliminated through an opening adjustment to retained earnings. The adoption of this standard also resulted in an increase to both other assets and other liabilities to record right-of-use lease assets and corresponding lease liabilities for all of Mid Penn’s leased facilities. Please reference Note 24, Recent Accounting Pronouncements Operating and finance lease right-of-use 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. Mid Penn has elected not to include short-term leases (i.e., leases with initial terms of twelve months or less) on the Consolidated Balance Sheet. There were no sale and leaseback transactions, leveraged leases, or lease agreements that had not commenced as of December 31, 2019.

Short-term borrowings consist of federal funds purchased and advances from the FHLB with an original maturity of less than a year. Federal funds purchased from correspondent banks mature in one business day and reprice daily based on the Federal Funds rate. Advances from the FHLB are collateralized by our investment in the common stock of the FHLB and by a blanket lien on selected loan receivables comprised principally of real estate secured loans within the Bank’s portfolio totaling $1,162,899,000 at December 31, 2019. The Bank had short-term borrowing capacity from the FHLB up to the Bank’s unused borrowing capacity of $610,795,000 at December 31, 2019 upon satisfaction of any stock purchase requirements of the FHLB. The Bank also has unused overnight lines of credit with other correspondent banks amounting to $35,000,000 at December 31, 2019. No draws have been made on these lines of credit and on December 31, 2019 and 2018, the balance was zero. The following table outlines Mid Penn’s various sources of short-term borrowed funds at or for the years ended December 31, 2019 and 2018.

The First Priority Notes agreements were entered into by First Priority on November 13, 2015 with five accredited investors pursuant to which First Priority issued subordinated notes totaling $9,500,000. The First Priority Notes have a maturity date of November 30, 2025, and bear interest at a fixed rate of 7.00% per annum. The Notes are non-callable for an initial period of five years and include provisions for redemption pricing between 101.5% and 100.5% of the liquidation value if called after five years but prior to the stated maturity date. Subordinated Debt Issued December 2017 On December 19, 2017, Mid Penn entered into agreements with investors to purchase $10,000,000 aggregate principal amount of its Subordinated Notes due 2028 (the “2017 Notes”). The 2017 Notes are intended to be treated as Tier 2 capital for regulatory capital purposes. The offering closed in December 2017. The 2017 Notes will bear interest at a rate of 5.25% per year for the first five years and then float at the Wall Street Journal’s Prime Rate plus 0.50%, provided that the interest rate applicable to the outstanding principal balance will at no times be less than 5.0%. Interest will be payable semi-annually in arrears on January 15 and July 15 of each year, beginning on July 15, 2018, for the first five years after issuance and will be payable quarterly in arrears thereafter on January 15, April 15, July 15, and October 15. The 2017 Notes will mature on January 1, 2028 and are redeemable in whole or in part, without premium or penalty, at any time on or after December 21, 2022, and prior to January 1, 2028. Additionally, Mid Penn may redeem the 2017 Notes in whole at any time, or in part from time to time, upon at least 30 days’ notice if: (i) a change or prospective change in law occurs that could prevent Mid Penn from deducting interest payable on the 2017 Notes for U.S. federal income tax purposes; (ii) an event occurs that precludes the 2017 Notes from being recognized as Tier 2 capital for regulatory capital purposes; or (iii) Mid Penn becomes required to register as an investment company under the Investment Company Act of 1940, as amended. In the event of a redemption described in the previous sentence, Mid Penn will redeem the 2017 Notes at 100% of the principal amount of the 2017 Notes, plus accrued and unpaid interest thereon to but excluding the date of redemption.

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	(1 4 ) Fair Value Measurement Fair value measurement and disclosure guidance defines fair value as the price that would be received to sell the asset or transfer the liability in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. This guidance provides additional information on determining when the volume and level of activity for the asset or liability has significantly decreased. The guidance also includes information on identifying circumstances when a transaction may not be considered orderly. Fair value measurement and disclosure guidance provides a list of factors that a reporting entity should evaluate to determine whether there has been a significant decrease in the volume and level of activity for the asset or liability in relation to normal market activity for the asset or liability. When the reporting entity concludes there has been a significant decrease in the volume and level of activity for the asset or liability, further analysis of the information from that market is needed and significant adjustments to the related prices may be necessary to estimate fair value in accordance with the fair value measurement and disclosure guidance. This guidance clarifies that when there has been a significant decrease in the volume and level of activity for the asset or liability, some transactions may not be orderly. In those situations, the entity must evaluate the weight of the evidence to determine whether the transaction is orderly. The guidance provides a list of circumstances that may indicate that a transaction is not orderly. A transaction price that is not associated with an orderly transaction is given little, if any, weight when estimating fair value. Inputs to valuation techniques refer to the assumptions that market participants would use in measuring the fair value of an asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own belief about the assumptions market participants would use in pricing the asset or liability based upon the best information available in the circumstances. Fair value measurement and disclosure guidance establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. An asset’s or liability’s placement in the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement or disclosure. The fair value hierarchy is as follows: Level 1 Inputs - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 Inputs - Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability; Level 3 Inputs - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. There were no transfers of assets between fair value Level 1 and Level 2 for the years ended December 31, 2019 or 2018. The following tables illustrate the assets measured at fair value on a recurring basis segregated by hierarchy fair value levels: Fair value measurements at December 31, 2019 using: (Dollars in thousands) Total carrying value at Quoted prices in active markets Significant other observable inputs Significant unobservable inputs Assets: December 31, 2019 (Level 1) (Level 2) (Level 3) Available-for-sale debt securities: U.S. government agencies $ 22,830 $ — $ 22,830 $ — Mortgage-backed U.S. government agencies 12,890 — 12,890 — State and political subdivision obligations 30 — 30 — Corporate debt securities 1,259 — 1,259 — Other assets: Equity securities 507 507 — — $ 37,516 $ 507 $ 37,009 $ — Fair value measurements at December 31, 2018 using: (Dollars in thousands) Total carrying value at Quoted prices in active markets Significant other observable inputs Significant unobservable inputs Assets: December 31, 2018 (Level 1) (Level 2) (Level 3) Available-for-sale debt securities: U.S. government agencies $ 41,572 $ — $ 41,572 $ — Mortgage-backed U.S. government agencies 38,849 — 38,849 — State and political subdivision obligations 29,256 — 29,256 — Corporate debt securities 2,246 — 2,246 — Other assets: Equity securities 492 492 — — $ 112,415 $ 492 $ 111,923 $ — Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following tables illustrate the assets measured at fair value on a nonrecurring basis segregated by hierarchy fair value levels.

(b) Appraisals may be adjusted downward by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range of liquidation expenses and other appraisal adjustments are presented as a percent of the appraisal. Higher downward adjustments are caused by negative changes to the collateral or conditions in the real estate market, actual offers or sales contracts received, or age of the appraisal. The following methodologies and assumptions were used to estimate the fair value of certain assets and liabilities: Securities Available for Sale: The fair value of securities classified as available for sale is determined by obtaining quoted market prices on nationally recognized securities exchanges (Level 1), or matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather relying on the securities’ relationship to other benchmark quoted prices. Impaired Loans (Included in “Net Loans and Leases” in the following table): All performing troubled debt restructured loans and loans classified as nonaccrual are deemed to be impaired, and all of these loans are considered collateral dependent; therefore, all of Mid Penn’s impaired loans, whether reporting a specific allowance allocation or not, are considered collateral dependent. It is Mid Penn’s policy to obtain updated third party valuations on all impaired loans collateralized by real estate within 30 days of the credit being classified as substandard nonaccrual. Prior to receipt of the updated real estate valuation, Mid Penn will use existing real estate valuations to determine any potential allowance for loan loss issues, and will update the allowance impact calculation upon receipt of the updated real estate valuation. 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. Mid Penn considers the estimates used in its impairment analysis to be Level 3 inputs. Mid Penn actively monitors the values of collateral on impaired loans. This monitoring may require the modification of collateral values, either in a positive or negative way, due to the passage of time or some other change in one or more valuation inputs. Collateral values for impaired loans will be reassessed by management at least every 12 months for possible revaluation by an independent third party. Foreclosed Assets Held for Sale: Certain assets included in foreclosed assets held for sale are carried at fair value and accordingly is presented as measured on a non-recurring basis. Values are estimated using Level 3 inputs, based on appraisals that consider the sales prices of property in the proximate vicinity. The following table summarizes the carrying value and fair value of financial instruments at December 31, 2019 and 2018.

Defined Benefit Pension Plans And Defined Benefit Postretirement Plans Disclosure [Abstract]
Postretirement Benefit Plans	(1 5 ) Postretirement Benefit Plans Mid Penn has an unfunded noncontributory defined benefit plan for directors, which provides defined benefits based on the respective director’s years of service, as well as a postretirement healthcare and life insurance benefit plan, which is noncontributory, covering certain full-time employees. Mid Penn also assumed a noncontributory defined benefit pension plan as a result of the acquisition of Scottdale on January 8, 2018. Service costs related to plans benefiting Mid Penn employees are reported as a component of salaries and employee benefits on the Consolidated Statements of Income, while interest costs, expected return on plan assets, amortization (accretion) of prior service cost, and settlement gain are reported as a component of other income. Service costs, interest costs, and amortization of prior service costs related to plans benefiting Mid Penn’s nonemployee directors are reported as a component of director fees and benefits expense within the other expense line item on the Consolidated Statement of Income. The accrued benefit liability, related income statement impacts, and other significant aspects of the plans are detailed below. (a) Life Insurance Full-time employees who had at least ten years of service as of January 1, 2008 and retire with the Bank after age 55 and at least 20 years of service are eligible for term life insurance coverage. The insurance amount will be $50,000 until age 65. After age 65, the insurance amount will decrease by $5,000 per year until age 74. Thereafter, the insurance amount will be $5,000. (b) Health and Life Benefit Plan Full-time employees who had at least 10 years of service as of January 1, 2008 and who retire at age 55 or later, after completion of at least 20 years of service, are eligible for medical benefits. Medical benefits are provided for up to five years after retirement. Employees who retired prior to December 31, 2015 may elect the least expensive single coverage in the employer’s group medical plan. If the retiree becomes eligible for Medicare during the five year duration of coverage, the Bank will pay, at its discretion, premiums for single 65-special coverage or similar supplemental coverage. For those employees who retired between September 18, 2015 and December 31, 2015, the Bank will only pay up to $5,000 towards such medical coverage. Employees who retired after December 31, 2015 may not participate in the employer’s group medical plan. Instead, the Bank will reimburse the retiree for up to $5,000 (grossed up by 36.79 percent as of December 31, 2019) in medical costs. The following tables provide a reconciliation of the changes in the plan’s health and life insurance benefit obligations and fair value of plan assets for the years ended December 31, 2019 and 2018, and a statement of the funded status at December 31, 2019 and 2018.

Employees who had achieved ten years of service as of January 1, 2008 and subsequently retire after at least 20 years of service are eligible for reimbursement of major medical insurance premiums up to $5,000, if the employee has not yet reached age 65. Upon becoming eligible for Medicare, Mid Penn will reimburse up to $5,000 in premiums for Medicare Advantage or a similar supplemental coverage. The maximum reimbursement period will not exceed five years regardless of retirement age and will end upon the participant obtaining other employment where major medical coverage is available or the participant’s death. The amount recognized in other liabilities on the consolidated balance sheets at December 31, 2019 and 2018, is as follows: (Dollars in thousands) 2019 2018 Accrued benefit liability $ 404 $ 475 The amounts recognized in accumulated other comprehensive loss consist of: (Dollars in thousands) December 31, 2019 2018 Net gain, pretax $ (50 ) $ (76 ) Net prior service cost, pretax (64 ) (89 ) The accumulated benefit obligation for health and life insurance plans was $404,000 and $475,000 at December 31, 2019 and 2018, respectively. There will be $25,000 in estimated prior service costs amortized from accumulated other comprehensive income into net periodic benefit cost during 2020. The components of net periodic postretirement benefit (income) cost for 2019, 2018 and 2017 are as follows: (Dollars in thousands) 2019 2018 2017 Service cost $ 3 $ 4 $ 4 Interest cost 17 17 20 Amortization of prior service cost (25 ) (25 ) (35 ) Amortization of net (gain) or loss (5 ) (1 ) — Net periodic postretirement benefit (income) cost $ (10 ) $ (5 ) $ (11 ) Assumptions used in the measurement of Mid Penn’s benefit obligations at December 31, 2019 and 2018 are as follows: Weighted-average assumptions: 2019 2018 Discount rate 3.00 % 4.00 % Rate of compensation increase 2.00 % 3.00 % Assumptions used in the measurement of Mid Penn’s net periodic benefit cost for the years ended December 31, 2019, 2018 and 2017 are as follows: Weighted-average assumptions: 2019 2018 2017 Discount rate 4.00 % 3.50 % 4.00 % Rate of compensation increase 3.00 % 2.50 % 3.00 % Assumed health care cost trend rates at December 31, 2019, 2018 and 2017 are as follows: 2019 2018 2017 Health care cost trend rate assumed for next year 5.50 % 5.50 % 6.00 % Rate to which the cost trend rate is assumed to decline (the ultimate trend rate) 5.40 % 5.40 % 5.40 % Year that the rate reaches the ultimate trend rate 2024 2022 2024 Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans.

The adoption of this plan generated unrecognized prior service cost of $274,000, which had been amortized over the expected future years of service of active directors, of which $22,000 was recognized in 2018 and was fully amortized as of December 31, 2018. The following tables provide a reconciliation of the changes in the directors’ defined benefit plan’s benefit obligations and fair value of plan assets for the years ended December 31, 2019 and 2018, and a statement of the status at December 31, 2019 and 2018.

The aggregate cash surrender value of these policies was $3,921,000 and $3,976,000 at December 31, 2019 and 2018, respectively. (a) Defined Benefit Pension Plan As a result of the acquisition of Scottdale on January 8, 2018, Mid Penn has assumed a noncontributory defined benefit pension plan covering certain former employees of Scottdale. After the acquisition, Mid Penn does not allow for any further participants to join the Plan. Mid Penn’s policy is to fund pension benefits as accrued. The Plan’s assets are managed by the Trust Department of the Bank and were primarily invested in corporate equity securities at the time of acquisition, but have since been diversified into a more conservative investment profile, including fixed income debt securities. The investment objective of the plan is “Balanced” to provide relatively stable growth from assets offset by a moderate level of income with target portfolio allocations of up to 20% cash, 30-50% fixed income securities, and 40-60% equity securities. The valuation of the plan’s assets are subject to market fluctuations. For the years ended December 31, 2019 and 2018, Mid Penn recognized $34,000 and $737,000 of settlement gains, respectively, as a result of certain lump sum payouts to participants of the defined benefit pension plan. The settlement gains were recorded in noninterest income as a component of other income in the Consolidated Statements of Income for the years ended December 31, 2019 and 2018. The following tables provide a reconciliation of the changes in the defined benefit pension plan’s benefit obligations and fair value of plan assets for the year ended December 31, 2019 and 2018, and a statement of the status at December 31, 2019 and 2018.

Common Stocks Valued at the closing price reported on the active market on which the individual securities are traded. Corporate Bonds Valued using matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather relying on the securities’ relationship to other benchmark quoted prices. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Plan 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 certain financial instruments could result in a different fair value measurement at the reporting date. Mid Penn expects to contribute $200,000 to the defined benefit pension plan in 2020. The following table shows the estimated benefit payments for future periods.

Other Benefit Plans	(1 6 ) Other Benefit Plans Mid Penn maintains several benefit plans for both current and former employees of the Bank. Liabilities related to the plans are recorded in other liabilities on the balance sheet, and aggregate cash surrender values assets related to the life insurance plans are recorded in the cash surrender value of life insurance line item on the balance sheet. Significant aspects of the plans are detailed below. (a) 401(k) Plan The Bank has a 401(k) plan that covers substantially all full-time employees. The plan allows employees to contribute a portion of their salaries and wages to the plan and provides for the Bank to match a portion of employee-elected salary deferrals, subject to certain percentage maximums of their salaries and wages. The Bank’s contribution to the 401(k) Plan was $680,000, $514,000, and $383,000 for the years ending December 31, 2019, 2018, and 2017, respectively and is included as a component of salaries and benefits expense in the Consolidated Statements of Income. During 2018, Mid Penn assumed the 401(k) plans of Scottdale and First Priority and, as of December 31, 2019 and 2018, these 401(k) plans were managed collectively by Mid Penn’s Human Resources and Trust areas. These 401(k) plans were frozen and no contributions were made to the plans in 2019 or 2018. (b) Defined-Contribution Plan The Bank has a funded contributory defined-contribution plan covering substantially all employees. The Bank did not contribute to the plan in 2019, 2018, or 2017. (c) Deferred Compensation Plans The Bank has an executive deferred compensation plan, which allows executive officers to defer compensation for a specified period in order to provide future retirement income. The only participant in the plan is a former executive officer. The Bank accrued a liability for the plan of approximately $87,000 at December 31, 2019 and $106,000 at December 31, 2018. The expense related to the plan was $4,000 in 2019, $5,000 in 2018, and $5,000 in 2017 and is included as a component of salaries and benefits expense in the Consolidated Statements of Income. The Bank also has a directors’ deferred compensation plan, which allows directors to defer receipt of director fees for a specified period in order to provide future retirement income. At December 31, 2019 and 2018, the Bank accrued a liability of $1,044,000 and $838,000, respectively, for this plan. The expense related to the plan was $41,000 in 2019, $31,000 in 2018, and $25,000 in 2017 and is included as a component of other expense in the Consolidated Statements of Income. (d) Salary Continuation Agreement The Bank maintains a Salary Continuation Agreement (“Agreement”) for a former executive officer. The Agreement provides the former executive officer with a fixed annual benefit. The benefit is payable beginning at age 65 for a period of 15 years. At December 31, 2019 and 2018, the Bank accrued a liability of approximately $224,000 and $236,000, respectively, for the Agreement. The expense related to the Agreement was $16,000 for 2019, $17,000 for 2018, and $17,000 for 2017 and is included as a component of salaries and benefits expense in the Consolidated Statements of Income. The Bank is the owner and beneficiary of an insurance policy on the life of the participating former executive officer, which supports the funding of the benefit obligation. The aggregate cash surrender value of this policy was approximately $1,387,000 and $1,352,000 at December 31, 2019 and 2018, respectively. (e) Split Dollar Life Insurance Arrangements At December 31, 2019 and 2018, the Bank had Split Dollar Life Insurance arrangements with two former executives for which the aggregate collateral assignment and cash surrender values are approximately $1,396,000 and $1,387,000, respectively. Mid Penn acquired Phoenix’s Split Dollar Life Insurance arrangements in 2015 on select employees, which had aggregate cash surrender values of $4,094,000 at December 31, 2019 and $4,010,000 at December 31, 2018. (f) Employee Stock Purchase Plan Mid Penn has an Employee Stock Purchase Plan (“ESPP”) in which all employees are eligible to participate. The plan allows employees to use a portion of their salaries and wages to purchase shares of Mid Penn common stock at the market value of shares at the end of each calendar quarter. A summary of shares purchased and average purchase price for the years ended December 31, 2019, 2018, and 2017 is presented below. 2019 2018 2017 ESPP shares purchased 5,151 4,132 3,578 Average purchase price per share $ 26.015 $ 28.716 $ 29.027 (g) Director Stock Purchase Plan On May 24, 2017, the Board of Directors of Mid Penn approved the Director Stock Purchase Plan (“DSPP”). The purpose of the DSPP is to provide non-employee directors of Mid Penn with a convenient means to purchase Corporation common stock at fair market value on the last day of each calendar quarter. The plan was effective beginning July 1, 2017. A summary of shares purchased and average purchase price for the years ended December 31, 2019, 2018, and 2017 is presented below. 2019 2018 2017 DSPP shares purchased 5,232 4,296 1,345 Average purchase price per share $ 25.852 $ 28.940 $ 31.136 (h) Supplemental Executive Retirement Plan During August 2018, Mid Penn entered into supplemental executive retirement plan agreements (“SERPs”) with four named executive officers. A fifth named executive officer entered into a SERP during May of 2019. Each SERP provides for the monthly payment of a fixed cash benefit over a period of fifteen (15) years, commencing on the first day of the month following the Executive’s separation from service: (i) occurring on or after reaching normal retirement age (age 70); (ii) due to disability; (iii) due to death; or (iv) within two (2) years following a change in control of the Bank. One-half of the benefit vests on January 1, 2022, with an additional 10% vesting each January 1 thereafter until fully vested on January 1, 2027. Any unvested portion of the benefit fully vests upon a change in control of the Bank. The accrued liability for the supplemental retirement plans was $296,000 at December 31, 2019 and $73,000 as of December 31, 2018.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and prudent, feasible and permissible as well as available tax planning strategies in making this assessment. At December 31, 2019, based on the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that Mid Penn will realize the benefits of these deferred tax assets and has no valuation allowances recorded against any components of its deferred tax asset, including the carryforward balances related to net operating losses (NOL), Section 1231 losses, and charitable contribution carryforwards. The annual usage of acquired NOL, charitable contribution carryforwards, and Section 1231 losses is limited by IRS Section 382 regulations. These limitations are calculated separately for each acquisition as the federal long-term tax exempt rate at the date of acquisition multiplied by the valuation of the selling company as calculated in accordance with GAAP. As a result, the usage of acquired NOLs, charitable contribution carryforwards, and Section 1231 losses to offset taxable income related to the Scottdale acquisition is limited to $1,313,000 per year, and $1,854,000 per year for the First Priority acquisition. At December 31, 2019 and 2018, Mid Penn had NOL carryforwards of $3,008,000 and $5,465,000 resulting from the 2018 acquisitions First Priority and Scottdale that are available to offset future taxable income. The entire balance of the NOL acquired from Scottdale of $1,238,000 has been fully utilized as of December 31, 2019. Of the $3,008,000 balance at December 31, 2019, $447,000 was attributable to NOL carryforwards generated prior to December 31, 2017 and acquired from First Priority and are scheduled to expire in 2031 and 2032. The remaining $2,561,000 was attributable to NOL carryforwards generated after January 1, 2018 and acquired from First Priority. The NOL carryforwards generated after January 1, 2018 do not expire; however, Mid Penn is limited to a deduction of the lesser of the available NOL carryforward or 80 percent of pre-NOL taxable income in a single tax year as set forth in the Tax Cuts and Jobs Act. At December 31, 2019 and 2018, charitable contribution carryforwards totaled $785,000 and $1,157,000, respectively, and are scheduled to expire between 2020 and 2022. During 2019, $211,000 of charitable contribution carryforwards were written off, resulting in $44,000 of additional tax expense recorded upon the filing of the final 2018 tax return during the third quarter of 2019. Mid Penn expects to generate sufficient taxable income to utilize all charitable contribution carryforwards in the future. The Tax Cuts and Jobs Act (TCJA) enacted on December 22, 2017 repealed Corporate Alternative Minimum Tax (AMT). As a result, the AMT carryforward balances of $860,000 and $1,433,000 as of December 31, 2019 and 2018, respectively, will be systematically refunded with each return until fully refunded no later than the filing of the Corporation’s December 31, 2021 tax return. Acquired Section 1231 losses totaling $314,000 were recorded as a result of filing the final First Priority return in 2019 and expire in 2022. On December 22, 2017, the TCJA was signed into law, reducing the federal tax rate to 21% beginning on January 1, 2018. The revaluation of net deferred tax assets as of December 22, 2017 resulted in $1,169,000 of additional tax expense on the date of enactment included in deferred expense in the tables below. The provision for income taxes consists of the following: (Dollars in thousands) 2019 2018 2017 Current tax provision Federal $ 2,875 $ 812 $ 2,672 State 185 — — Total current tax provision 3,060 812 2,672 Deferred tax expense Federal $ 665 1,317 $ 1,828 State — — — Total deferred tax expense $ 665 1,317 1,828 Total provision for income taxes $ 3,725 $ 2,129 $ 4,500 A reconciliation of federal income tax at the statutory rate of 21% for 2019 and 2018, and 34% for 2017 to Mid Penn's effective rate is as follows: (Dollars in thousands) 2019 2018 2017 Provision at the expected statutory rate $ 4,499 $ 2,672 $ 3,940 Effect of tax-exempt income (683 ) (704 ) (668 ) Effect of investment in life insurance (66 ) (60 ) (89 ) State income taxes, net of federal tax benefit 146 — — Nondeductible interest 59 40 30 Low income housing partnership tax credits (83 ) (168 ) (46 ) Nondeductible merger and acquisition expense — 193 191 Rate change adjustment — — 1,169 Other items (147 ) 156 (27 ) Provision for income taxes $ 3,725 $ 2,129 $ 4,500 Mid Penn has no unrecognized tax benefits that, if recognized, would favorably affect the effective income tax rate in future periods. Mid Penn does not expect the total amount of unrecognized tax benefits to significantly increase or decrease in the next twelve months. No amounts for interest and penalties were recorded in income tax expense in the consolidated statement of income for the years ended December 31, 2019, 2018, or 2017. There were no amounts accrued for interest and penalties at December 31, 2019 or 2018. Mid Penn and its subsidiaries are subject to U.S. federal income tax and income tax for the state of Pennsylvania and New Jersey. With limited exceptions, Mid Penn is no longer subject to examination by taxing authorities for years before 2016.

Regulatory Capital Requirements [Abstract]
Regulatory Matters	(1 8 ) Regulatory Matters Mid Penn Bancorp, Inc., is a financial holding company and maintains a well-capitalized status in both the consolidated Corporation and in its bank subsidiary. Quantitative measures established by regulation to ensure capital adequacy require Mid Penn to maintain minimum amounts and ratios (set forth below) of Tier 1 Capital to average assets and of Total Capital (as defined in the regulations) to risk-weighted assets. As of December 31, 2019 and December 31, 2018, Mid Penn met all capital adequacy requirements to which the Bank is subject, and the Bank is considered “well-capitalized”. However, future changes in regulations could increase capital requirements and may have an adverse effect on capital resources. The federal banking agencies have substantially amended the regulatory risk-based capital rules applicable to Mid Penn. The amendments implemented the Basel III regulatory capital reforms and changes required by the Dodd-Frank Act. The amended rules included new minimum risk-based capital and leverage ratios, which became effective in January 2015, with certain requirements phased in beginning in 2016, and refined the definition of what constitutes "capital" for purposes of calculating those ratios. The revised minimum capital level requirements applicable to Mid Penn include: (i) a new common equity Tier I capital ratio of 4.5%; (ii) a Tier I capital ratio of 6.0% (increased from 4.0 %); (iii) a Total Capital ratio of 8.0% (unchanged from prior rules); and (iv) a Tier I leverage ratio of 4.0% for all institutions. The amended rules also established a "capital conservation buffer" of 2.5% above the revised regulatory minimum capital ratios, which result in the following minimum ratios: (i) a common equity Tier I capital ratio of 7.0%; (ii) a Tier I capital ratio of 8.5%; and (iii) a Total Capital ratio of 10.5%. The new capital conservation buffer requirement was phased in beginning in January 2016 at 0.625% of risk-weighted assets and increased each year until fully implemented in January 2019. An institution will be subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if its capital level falls below the buffer amount. These limitations will establish a maximum percentage of eligible retained income that could be utilized for such actions. The final rules allowed community banks to make a one-time election not to include the additional components of accumulated other comprehensive income (“AOCI”) in regulatory capital and instead use the existing treatment under the general risk-based capital rules that excludes most AOCI components from regulatory capital. Mid Penn made the election not to include the additional components of AOCI in regulatory capital. The final rules permanently grandfathered non-qualifying capital instruments (such as trust preferred securities and cumulative perpetual preferred stock) issued before May 19, 2010 for inclusion in the Tier 1 capital of banking organizations with total consolidated assets less than $15 billion as of December 31, 2009 and banking organizations that were mutual holding companies as of May 19, 2010. Consistent with the Dodd-Frank Act, the new rules replaced the ratings-based approach to securitization exposures, which is based on external credit ratings, with the simplified supervisory formula approach in order to determine the appropriate risk weights for these exposures. Alternatively, banking organizations may use the existing gross-ups approach to assign securitization exposures to a risk weight category or choose to assign such exposures a 1,250% risk weight. Under the new rules, mortgage servicing assets (“MSAs”) and certain deferred tax assets (“DTAs”) are subject to stricter limitations than those applicable under the current general risk-based capital rule. The new rules also increase the risk weights for past-due loans, certain risk weights and credit conversion factors. Mid Penn has implemented these changes in determining and reporting the regulatory ratios of Mid Penn and the Bank, and has concluded that the new rules did not have a material adverse effect on Mid Penn’s financial condition. Certain restrictions exist regarding the ability of the Bank to transfer funds to the Corporation in the form of cash dividends, loans, or advances. The amount of dividends that may be paid from the Bank to the Corporation in any calendar year is limited to the Bank’s current year’s net profits, combined with the retained net profits of the preceding two years. For the year ended December 31, 2019, $12,486,000 of undistributed earnings of the Bank, included in the consolidated shareholders’ equity balance, was available for distribution to the Corporation as dividends without prior regulatory approval, subject to regulatory capital requirements below.

Concentration Risks Types No Concentration Percentage [Abstract]
Concentration Risk and Off-Balance Sheet Risk	( 19 ) Concentration of Risk and Off-Balance Sheet Risk The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The Bank evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management's credit evaluation of the borrower. Collateral held varies but may include accounts receivable, inventory, property, plant, and equipment, and income-producing commercial properties. The Bank's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit written is represented by the contractual amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for direct, funded loans. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The term of these standby letters of credit is generally one year or less. The amount of the liability as of December 31, 2019 and 2018 for guarantees under letters of credit issued is not considered material. As of December 31, 2019, commitments to extend credit amounted to $435,553,000 and standby letters of credit amounted to $26,574,000. As of December 31, 2018, commitments to extend credit amounted to $346,238,000 and standby letters of credit amounted to $20,839,000. Additionally, Mid Penn has sold loans to the FHLB as part of its Mortgage Partnership Finance Program (“Program”). Under the terms of the Program, there is limited recourse back to Mid Penn for loans that do not perform in accordance with the terms of the loan agreement. Each loan that is sold under the Program is “credit enhanced” such that the individual loan’s rating is raised to “BBB”, as determined by the FHLB. The Program can be terminated by either the FHLB or Mid Penn, without cause, by giving notice to the other party. The FHLB has no obligation to commit to purchase any mortgage through, or from, Mid Penn. The total balance of loans sold under the Program was $4,610,000 and $5,836,000 for the years ended December 31, 2019 and 2018, respectively. Significant concentration of credit risk may occur when obligations of parties engaged in similar activities occur and accumulate in significant amounts. In analyzing the Bank's exposure to significant concentration of credit risk, management set a parameter of 10% or more of the Bank's total net loans outstanding as the threshold in determining whether the obligations of the same or affiliated parties would be classified as significant concentration of credit risk. Concentrations by industry, product line, type of collateral, etc., are also considered. U.S. Treasury securities, obligations of U.S. government agencies and corporations, and any assets collateralized by the same were excluded. As of December 31, 2019, commercial real estate financing was the only similar activity that met the requirements to be classified as a significant concentration of credit risk. However, there is a geographical concentration in that most of the Bank's business activity is with customers located in twelve counties in Pennsylvania. The Bank's highest industry concentration within the loan portfolio is in commercial real estate financing, which was 63.0 % and 61.8% as of December 31, 2019 and 2018, respectively.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(2 0 ) Commitments and Contingencies Commitments During the second quarter of 2018, Mid Penn entered into a commitment to purchase a limited partnership interest in a low-income housing project to construct thirty-seven apartments and common amenities in Dauphin County, Pennsylvania. All of the units are intended to qualify 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 $7,579,000, which will be paid in installments over the course of construction of the low-income housing facilities. Each installment payment is conditional upon both Mid Penn’s review and approval of the installment payment certificate and continued compliance with the terms of the original partnership agreement. The project has been conditionally awarded $861,000 in annual LIHTCs by the Pennsylvania Housing Finance Agency, with a total anticipated LIHTC amount of $8,613,000 to be awarded to Mid Penn over the ten year amortization period. Mid Penn’s commitment to initiate investments in the limited partnership interest was conditional upon (i) the review and approval of all closing documents, (ii) an opinion letter for tax counsel to the Partnership that the project qualifies for the LIHTCs, and (iii) review and approval by Mid Penn of other documents it deemed necessary. All such initial conditions were satisfied and Mid Penn began funding the investment during 2018 and is expected to be fully funded in 2020. As of December 31, 2019, the units were substantially complete and met the occupancy requirements necessary to begin recognizing the related amortization and tax credits using the cost amortization method over a ten year period. The carrying value of Mid Penn’s investment in the limited partnership is reported within other assets on the Consolidated Balance Sheet and totaled $7,249,000 at December 31, 2019 and $1,710,000 at December 31, 2018. Litigation Mid Penn is subject to lawsuits and claims arising out of its normal conduct of business. In the opinion of management, after consultation with legal counsel, the ultimate disposition of these matters is not expected to have a material adverse effect on the consolidated financial condition of Mid Penn.

Common Stock	(21 ) Common Stock Authorized Shares At the May 14, 2019 annual shareholder meeting, Mid Penn shareholders approved an amendment to the Articles of Incorporation to increase the number of authorized shares of common stock from 10,000,000 shares to 20,000,000 shares. Dividend Reinvestment Plan Under Mid Penn’s amended and restated dividend reinvestment plan (“DRIP”), 330,750 shares of Mid Penn’s authorized but unissued common stock are reserved for issuance. The DRIP also allows for voluntary cash payments, within specified limits, to be used for the purchase of additional shares. Restricted Stock Plan On June 25, 2014, the 2014 Restricted Stock Plan was registered under which awards shall not exceed, in the aggregate, 100,000 shares of common stock. The Plan was established for employees and directors of Mid Penn and the Bank, selected by the Compensation Committee of the Board of Directors, to advance the best interest of Mid Penn and its shareholders. The plan provides those persons who have a responsibility for its growth with additional incentives by allowing them to acquire an ownership interest in Mid Penn and thereby encouraging them to contribute to the success of the company. As of December 31, 2019, 57,655 shares have been granted under the Plan, of which 2,346 shares were forfeited and available for reissuance. During 2019, Mid Penn granted 18,450 restricted shares, 11,650 of which were granted to employees, while 6,800 were granted to directors. Mid Penn granted 12,250 restricted shares in 2018, 7,450 of which were granted to employees, while 4,800 were granted to directors. Throughout 2017, Mid Penn granted 10,440 restricted shares, 6,040 of which were granted to employees, while 4,400 were granted to directors. No restricted shares were forfeited in 2019. In 2018, 1,876 granted shares were forfeited to Mid Penn due to the termination of employment of three plan participants, while no shares were forfeited in 2017. Share-based compensation expense relating to restricted stock is calculated using grant date fair value and is recognized on a straight-line basis over the vesting periods of the awards. Restricted shares granted to employees vest in equal amounts on the anniversary of the grant date over a four year vesting period, and the expense is a component of salaries and benefits expense on the Consolidated Statements of Income. Restricted shares granted to directors have a twelve month vesting period, and the expense is a component of directors’ fees and benefits within the other expense line item on the Consolidated Statements of Income. The following table presents compensation expense and related tax benefits for restricted stock awards recognized on the consolidated statements of income.

New Accounting Pronouncement Or Change In Accounting Principle Retrospective Adjustments [Abstract]
Recent Accounting Pronouncements	(2 4 ) Recent Accounting Pronouncements Accounting Standards Adopted in 2019 ASU 2019-04: The FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. As previously reported on a Form 8-K filed on November 20, 2019, Mid Penn early adopted ASU 2019-04, and as part of the adoption, reclassified 113 held-to-maturity debt securities consisting primarily of state and political subdivision obligations and mortgage-backed U.S. government agencies with an aggregate amortized cost of $67,096,000 to the available-for-sale category. All 113 securities were subsequently sold during the fourth quarter of 2019, and Mid Penn realized a pre-tax gain on the sales of $1,779,000. Proceeds from the sales are primarily intended to fund future loan growth or repay wholesale borrowings. ASU 2016-02: The FASB issued ASU 2016-02, Leases. The new leases standard applies a right-of-use (“ROU”) model that requires a lessee to record, for all leases with a lease term of more than 12 months, an asset representing its right to use the underlying asset and a liability to make lease payments. For leases with a term of 12 months or less, a practical expedient is available whereby a lessee may elect, by class of underlying asset, not to recognize an ROU asset or lease liability. At inception, lessees must classify all leases as either finance or operating based on five criteria. Balance sheet recognition of finance and operating leases is similar, but the pattern of expense recognition in the income statement, as well as the effect on the statement of cash flows, differs depending on the lease classification. The new leases standard requires a lessor to classify leases as either sales-type, direct financing or operating, similar to existing U.S. GAAP. Classification depends on the same five criteria used by lessees plus certain additional factors. The subsequent accounting treatment for all three lease types is substantially equivalent to existing U.S. GAAP for sales-type leases, direct financing leases, and operating leases. However, the new standard updates certain aspects of the lessor accounting model to align it with the new lessee accounting model, as well as with the new revenue standard under Topic 606. Lessees and lessors are required to provide certain qualitative and quantitative disclosures to enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The new leases standard addresses other considerations including identification of a lease, separating lease and non-lease components of a contract, sale and leaseback transactions, modifications, combining contracts, reassessment of the lease term, and re-measurement of lease payments. It also contains comprehensive implementation guidance with practical examples. On July 30, 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, The amendments for both ASUs are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. Specific transition requirements apply. Mid Penn adopted this standard in the first quarter of 2019 using the option to apply the transition provisions of the new standard at the adoption date instead of the earliest period presented as provided in ASU 2018-11. Additionally, Mid Penn elected to apply all practical expedients as provided in ASU 2016-02, with the exception of the hindsight practical expedient, which was not elected. As a result of the adoption of this standard on January 1, 2019, Mid Penn recognized (i) an operating lease ROU asset of $11,661,000, (ii) an operating lease liability of $12,866,000, and (iii) an opening adjustment to retaining earnings of $316,000 to eliminate the remaining balance of the deferred sale/leaseback gain on two retail branch locations which had originally been recorded in 2016. The operating lease liability represents the present value of future payments on twenty-four leased properties within the Mid Penn footprint as of the January 1, 2019 adoption date, while the ROU asset reflects the lease liability, adjusted for deferred/accrued rent balances and the balance of acquisition accounting fair value adjustments of the respective properties as of the adoption date of January 1, 2019. Subsequent to the adoption of Topic 842, Mid Penn entered into a lease agreement for one facility under a non-cancelable finance lease which commenced March 1, 2019. Mid Penn recognized a finance lease ROU asset of $3,597,000 and a finance lease liability of $3,597,000 included in the reported amount of long-term debt as of the lease commencement date. The adoption of this standard did not have a material impact on the Consolidated Statements of Income or the Consolidated Statements of Cash Flow. See Note 9, Leases In March 2019, the FASB issued ASU No. 2019-01, “Leases: Codification Improvements.” significant amount of time between acquisition of the asset and lease commencement; (2) clarifies that lessors in the scope of ASC 842 (such as Mid Penn) must classify principal payments received from sales-type and direct financing leases in investing activities in the statement of cash flows; and (3) clarifies the transition guidance related to certain interim disclosures provided in the year of adoption. To coincide with the adoption of ASU No. 2016-02, Mid Penn elected to early adopt ASU 2019-01 on January 1, 2019. The adoption of this ASU did not have a material impact on Mid Penn’s Consolidated Financial Statements. ASU 2018-07: The FASB issued ASU 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting This ASU makes certain changes to the accounting for nonemployee awards to align the accounting for share-based payment awards issued to employees and nonemployees. The changes require that the compensation expense associated with nonemployee equity awards with performance conditions be recognized when the achievement of the performance condition is probable, rather than upon achievement of the performance condition. Additionally, the new ASU requires that equity-classified share-based payment awards issued to nonemployees be measured on the grant date, versus the previous GAAP requirement to re-measure the awards through the performance completion date. The current requirement to reassess the classification (equity or liability) for the nonemployee awards upon vesting will be eliminated. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, including interim periods. Mid Penn currently issues restricted stock awards to nonemployee directors through the 2014 Restricted Stock Plan (the “Plan”) as more fully described in Note 21. The single performance condition of the award is that the individual remain a director of Mid Penn through the duration of the vesting period. Mid Penn adopted this standard on January 1, 2019 and the adoption of this ASU did not have a material impact on our consolidated financial statements as the compensation expense related to nonemployee equity awards is immaterial to Mid Penn’s overall financial condition. Accounting Standards Adopted in 2018 ASU 2016-01: The FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . This ASU requires equity investments to be measured at fair value with changes in fair value recognized in net income, excluding equity investments that are consolidated or accounted for under the equity method of accounting. The ASU allows equity investments without readily determinable fair values to be measured at cost minus impairment, with a qualitative assessment required to identify impairment. The ASU also requires public companies to use exit prices to measure the fair value of financial instruments, eliminates the disclosure requirements related to measurement assumptions for the fair value of instruments measured at amortized cost, and requires separate presentation of financial assets and liabilities based on form and measurement category. In addition, for liabilities measured at fair value under the fair value option, the changes in fair value due to changes in instrument-specific credit risk should be recognized in OCI. This ASU is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, and was adopted by Mid Penn effective January 1, 2018. The adoption of this ASU resulted in the reclassification of equity securities to other assets (equity securities had previously been classified as available-for-sale investment securities). Also, related to this reclassification, a one-time cumulative-effect adjustment was recorded on January 1, 2018 that decreased retained earnings by $44,000, increased accumulated other comprehensive loss by $35,000, and decreased the deferred tax asset by $9,000. The impact on net income as a result of the adoption of this standard was immaterial for the year ended December 31, 2018. Additionally, the adoption of this ASU resulted in the refinement of our loan fair value calculation to comply with the exit price measurement requirement. The adoption of the exit price measurement requirement portion of this ASU did not have a material impact on Mid Penn’s fair value disclosures. In February 2018, the FASB issued ASU 2018-03, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, Accounting Standards Pending Adoption ASU 2018-15: The FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract This ASU requires an entity in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized implementation costs should be presented in the same line item on the balance sheet as amounts prepaid for the hosted service, if any (generally as an “other asset”). The capitalized costs will be amortized over the term of the hosting arrangement, with the amortization expense being presented in the same income statement line item as the fees paid for the hosted service. ASU 2018-15 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. Mid Penn adopted ASU 2018-15 effective January 1, 2020 on a prospective basis. ASU 2018-15 did not have a material impact on the results of operations. ASU 2018-13: The FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement This ASU, issued as part of the FASB’s disclosure framework project to improve the effectiveness of disclosures in financial statements, amends the disclosure requirements related to recurring and nonrecurring fair value measurements by removing, modifying, and adding certain disclosures. The ASU is effective for all entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. As a result of this ASU, several disclosures were removed from Topic 820, including: (i) disclosure of the valuation process for Level 3 fair value measurements, and (ii) amounts of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy. However, some additional disclosures will be required as a result of this ASU, including the requirement to disclose the changes in unrealized gains and losses included in other comprehensive income for the period related to Level 3 recurring fair value measurements, as well as the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. Mid Penn is currently evaluating the impact of this ASU on our current disclosures. The adoption of this standard may result in disclosure changes only and will not impact Mid Penn’s overall financial condition. ASU 2018-14: The FASB issued ASU 2018-14, Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans This ASU, issued as part of the FASB’s disclosure framework project to improve the effectiveness of disclosures in financial statements, amends the disclosure requirements related to defined benefit pension and other postretirement plans by removing and adding certain disclosures. The ASU is effective for public business entities for fiscal years ending after December 15, 2020. Early adoption is permitted. As a result of this ASU, several disclosures were removed from Topic 715, including: (i) disclosures of the amounts in accumulated comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, and (ii) the effects of a one-percentage point change in the assumed health care cost trend rates on the aggregate of service and interest cost components of net periodic postretirement health care benefit costs. However, some additional disclosures will be required as a result of this ASU, including the requirement to disclose an explanation for significant gains and losses related to changes in the benefit obligation for the period. Mid Penn is currently evaluating the impact of this ASU on our current disclosures. The adoption of this standard will result in disclosure changes only and will not impact Mid Penn’s overall financial condition. ASU 2016-13 : The FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, as further amended . The ASU requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (“CECL”) model). Under this model, entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications unless reasonable expectation of a troubled debt restructuring exists) from the date of initial recognition of that instrument. The ASU also replaces the current accounting model for purchased credit impaired loans and debt securities. The allowance for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (“PCD assets”) should be determined in a similar manner to other financial assets measured on an amortized cost basis. However, upon initial recognition, the allowance is added to the purchase price (“gross up approach”) to determine the initial amortized cost basis. The subsequent accounting for PCD financial assets is the same expected loss model described above. Further, the ASU made certain targeted amendments to the existing impairment model for available-for-sale debt securities. For an AFS debt security for which there is neither the intent nor a more-likely-than-not requirement to sell, an entity will record credit losses as an allowance rather than a write-down of the amortized cost basis. Certain incremental disclosures are required. Subsequently, the FASB issued ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-10, and ASU 2019-11 to clarify, improve, or defer the adoption of ASU 2016-13. In October 2019, the FASB issued ASU 2019-10 which deferred the implementation date of ASU 2016-13 for smaller reporting companies (SRCs) until January 1, 2023. The effective date for larger SEC filers would remain unchanged at January 1, 2020. Mid Penn qualifies as an SRC as of the most recent measurement date of June 30, 2019; therefore, Mid Penn has chosen to delay the adoption of ASU 2016-13. Mid Penn is currently evaluating the details of this ASU and the impact the guidance will have on Mid Penn’s consolidated financial statements. Mid Penn expects that it is possible that the ASU may result in an increase in the allowance for credit losses resulting from the change to expected losses for the estimated life of the financial asset, including an allowance for debt securities. The amount of the change in the allowance for credit losses, if any, resulting from the new guidance will be impacted by the portfolio composition and asset quality at the adoption date, as well as economic conditions and forecasts at the time of adoption. Mid Penn will continue to collect the required data elements needed to perform the calculation in advance of the January 1, 2023 adoption date. .

Accounting Policies [Abstract]
Use of Estimates	(a) Use of Estimates The preparation of financial statements 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 financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan and lease losses, the assessment of other-than-temporary impairment of investment securities, the valuation of the goodwill for impairment, and the valuation of assets acquired and liabilities assumed in business combinations.
Cash and Cash Equivalents	(b) 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	(c) 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, 2019 and 2018, there was no cash reserve balances required to be maintained at the Federal Reserve of Philadelphia because the Bank had sufficient vault cash available.
Investment Securities	(d) Interest-bearing Time Deposits with Other Financial Institutions Interest-bearing time deposits with other financial institutions consist of certificates of deposits in other financial institutions with maturities within one year. (e) Investment Securities Securities to be held for indefinite periods, but not intended to be held to maturity, are classified as available for sale and carried at fair value. Securities held for indefinite periods include securities that management intends to use as part of its asset and liability management strategy and that may be sold in response to liquidity needs, changes in interest rates, resultant prepayment risk, pledging requirements, and other factors related to effective portfolio management. For available-for-sale debt securities, realized gains and losses on dispositions are based on the difference between net proceeds and the amortized cost of the securities sold, using the specific identification method. Unrealized gains and losses on debt securities are based on the difference between the amortized cost and fair value of each security as of the respective reporting date. Unrealized gains and losses are credited or charged to other comprehensive income, whereas realized gains and losses flow through Mid Penn’s consolidated statement of income for the respective period. Securities to be held to maturity are carried at amortized cost. Unrealized holding gains and losses on held-to-maturity securities are excluded from earnings, and are not a component of accumulated other comprehensive income (loss) within shareholders’ equity. Premiums and discounts on debt securities are amortized as an adjustment to interest income using the interest method. Realized gains and losses on sales of investment securities are computed on the basis of specific identification of the cost of each security. ASC Topic 320, Investments – Debt Securities In instances when a determination is made that other-than-temporary impairment exists but the Company does not intend to sell the debt security and it is not more likely than not that it will be required to sell the debt security prior to its anticipated recovery, this guidance changes the presentation and amount of the other-than-temporary impairment recognized in the income statement. The other-than-temporary impairment is separated into (a) the amount of the total other-than-temporary impairment related to a decrease in cash flows expected to be collected from the debt security (the credit loss) and (b) the amount of the total other-than-temporary impairment related to all other factors. The amount of the total other-than-temporary impairment related to the credit loss is recognized in earnings. The amount of the total other-than-temporary impairment related to all other factors is recognized in other comprehensive income.
Equity Securities	(f) Equity Securities As a result of the adoption of ASU 2016-01 , Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities As of December 31, 2019 and December 31, 2018, Mid Penn’s equity securities consisted of Community Reinvestment Act funds totaling $507,000 and $492,000, respectively. No equity securities were sold during the years ended December 31, 2019 and December 31, 2018.
Loans Held for Sale	(g) Loans Held for Sale Mortgage loans originated and intended for sale in the secondary market are included in loans held for sale and are 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 the Consolidated Statements of Income in mortgage banking income.
Loans and Allowance for Loan and Lease Losses	(h) Loans and Allowance for Loan and Lease Losses Loans receivable 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 an allowance for loan losses and any deferred fees or costs. Interest income is accrued on the unpaid principal balance. Residential loans held for sale are carried at fair value and are included in loans held for sale on the balance sheet. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the yield (interest income) of the related loans, generally being amortized 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. The loan portfolio is segmented into commercial and consumer loans. Commercial loans consist of the following classes: commercial and industrial, commercial real estate, commercial real estate-construction and lease financing. Consumer loans consist of the following classes: residential mortgage loans, home equity loans and other consumer loans. For all classes of loans, the accrual of interest generally is discontinued when the contractual payment of principal or interest has become 90 days or more past due, or management has serious doubts about further collectability of principal or interest even though the loan is currently performing. A loan past due 90 days or more may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest is credited to income. Interest received on nonaccrual loans, including impaired loans, is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Nonaccrual loans may be restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time (generally, at least nine consecutive months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The past due status of all classes of loans receivable is determined based on contractual due dates for loan payments. Commercial and industrial Mid Penn originates commercial and industrial loans. Most of the Bank’s commercial and industrial loans have been extended to finance local and regional businesses and include short-term loans to finance machinery and equipment purchases, inventory, and accounts receivable. Commercial loans also involve the extension of revolving credit for a combination of equipment acquisitions and working capital in expanding companies. The maximum term for loans extended on machinery and equipment is based on the projected useful life of such machinery and equipment. Generally, the maximum term on non-mortgage lines of credit is one year. The loan-to-value ratio on such loans and lines of credit generally may not exceed 80 percent of the value of the collateral securing the loan. The Bank’s commercial business lending policy includes credit file documentation and analysis of the borrower’s character, capacity to repay the loan, the adequacy of the borrower’s capital and collateral, as well as an evaluation of conditions affecting the borrower. Analysis of the borrower’s past, present, and future cash flows is also an important aspect of the Bank’s current credit analysis. Nonetheless, such loans are believed to carry higher credit risk than other extensions of credit. Commercial and industrial loans typically are made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial business loans may be substantially dependent on the success of the business itself, which, in turn, is likely to be dependent upon the general economic environment. Mid Penn’s commercial and industrial loans are usually, but not always, secured by business assets and personal guarantees. However, the collateral securing the loans may depreciate over time, may be difficult to appraise, and may fluctuate in value based on the success of the business. Commercial real estate and commercial real estate - construction Commercial real estate and commercial real estate construction loans generally present a higher level of risk than loans secured by one-to-four family residences. This greater risk is due to several factors, including the concentration of principal in a limited number of loans and borrowers, the effect of general economic conditions on income producing properties, and the increased difficulty of evaluating and monitoring these types of loans. In addition, the repayment of loans secured by commercial real estate is typically dependent upon the successful operation of the related real estate project. If the cash flow from the project is reduced, the borrower’s ability to repay the loan may be impaired. Residential mortgage Mid Penn offers a wide array of residential mortgage loans for both permanent structures and those under construction. The Bank’s residential mortgage originations are secured primarily by properties located in its primary market and surrounding areas. Residential mortgage loans have terms up to a maximum of 30 years and with loan-to-value ratios up to 100 percent of the lesser of the appraised value of the security property or the contract price. Private mortgage insurance is generally required in an amount sufficient to reduce the Bank’s exposure to at or below the 85 percent loan-to-value level. Residential mortgage loans generally do not include prepayment penalties. In underwriting residential mortgage loans, the Bank evaluates both the borrower’s ability to make monthly payments and the value of the property securing the loan. Most properties securing real estate loans made by Mid Penn are appraised by independent fee appraisers. The Bank generally requires borrowers to obtain title insurance and fire and property insurance (including flood insurance, if necessary) in an amount not less than the amount of the loan. Real estate loans originated by the Bank generally contain a “due on sale” clause allowing the Bank to declare the unpaid principal balance due and payable upon the sale of the security property. The Bank underwrites residential mortgage loans to the standards established by the secondary mortgage market, i.e., Fannie Mae, Ginnie Mae, Freddie Mac, Federal Home Loan Bank or Pennsylvania Housing Finance Agency standards, with the intention of selling the majority of residential mortgages originated into the secondary market. In the event that the facts and circumstances surrounding a residential mortgage application do not meet all underwriting conditions of the secondary mortgage market, the Bank will evaluate the failed conditions and evaluate the potential risk of holding the residential mortgage in the Bank’s portfolio rather than rejecting the loan request. In the event that the loan is funded and held in the Bank’s portfolio, the interest rate on the residential mortgage would be increased to compensate for the added portfolio risk. Consumer, including home equity Mid Penn offers a variety of secured consumer loans, including home equity, automobile, and deposit secured loans. In addition, the Bank offers other secured and unsecured consumer loans. Most consumer loans are originated in Mid Penn’s primary market and surrounding areas. The largest component of Mid Penn’s consumer loan portfolio consists of fixed rate home equity loans and variable rate home equity lines of credit. Substantially all home equity loans and lines of credit are secured by junior lien mortgages on principal residences. The Bank will lend amounts, which, together with all prior liens, typically may be up to 85 percent of the appraised value of the property securing the loan. Home equity term loans may have maximum terms up to 20 years, while home equity lines of credit generally have maximum terms of five years. Consumer loan terms vary according to the type and value of collateral, length of contract and creditworthiness of the borrower. The underwriting standards employed by the Bank for consumer loans include an application, a determination of the applicant’s payment history on other debts, and an assessment of ability to meet existing obligations and payments on the proposed loan. Although creditworthiness of the applicant is a primary consideration, the underwriting process also includes a comparison of the value of the collateral, if any, in relation to the proposed loan amount. Consumer loans may entail greater credit risk than do residential mortgage loans, particularly in the case of consumer loans which are unsecured or are secured by rapidly depreciable assets, such as automobiles or recreational equipment. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be affected by adverse personal circumstances. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount that can be recovered on such loans. Junior liens inherently have more credit risk by virtue of the fact that another financial institution may have a higher security position in the case of foreclosure liquidation of collateral to extinguish the debt. Generally, foreclosure actions could become more prevalent if the real estate market weakens and property values deteriorate. Allowance for Loan and Lease Losses The allowance for credit losses (“allowance”) consists of (i) the allowance for loan and lease losses, and (ii) the reserve for unfunded lending commitments. The allowance for loan and lease losses 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 reserve for unfunded lending commitments was $80,000 at December 31, 2019 and $159,000 at December 31, 2018. The allowance is increased by the provision for loan and lease 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 and lease 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. The unallocated component of the allowance for loan and lease losses covers several considerations that are not specifically measureable through either the specific and general components. For example, at times Mid Penn could face increasing credit risks and uncertainties, not yet reflected in recent historical losses or qualitative factor assessments, associated with unpredictable changes in economic growth or business conditions in our markets or for certain industries in which we have commercial loan borrowers, or unanticipated stresses to the values of real estate held as collateral. Any or all of these additional issues can adversely affect our borrowers’ ability to timely repay their loans. Additionally, we have experienced continued strong commercial loan growth, including growth in newer markets where we have less of a loss history. Also, the unallocated component allocation recognizes the inherent imprecision in our allowance for loan and lease loss methodology, or any alternative methodology, for estimating specific and general loan losses, including the unpredictable timing and amounts of charge-offs, the fact that historical loss averages don’t necessarily correlate to future loss trends, and unexpected changes to specific-credit or general portfolio future cash flows and collateral values which could negatively impact unimpaired portfolio loss factors. Mid Penn generally considers a commercial loan (consisting of commercial and industrial, commercial real estate, commercial real estate-construction, and lease financing loan classes) to be impaired when it becomes 90 days or more past due and not in the process of collection, or sooner when it is probable that Mid Penn will be unable to collect all contractual principal and interest due. This methodology assumes the borrower cannot or will not continue to make additional payments. At that time, the loan would generally be considered collateral dependent as the discounted cash flows method would generally indicate no operating income available for evaluating the collateral position; therefore, most impaired loans are deemed to be collateral dependent. In addition, Mid Penn’s rating system assumes any loans classified as nonaccrual, included in the substandard rating, to be impaired, and most of these loans are considered collateral dependent; therefore, most of Mid Penn’s impaired loans, whether reporting a specific allocation or not, are considered collateral dependent. 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 nonaccrual, 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 nonperforming 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 nonperforming 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 nonperforming 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 nonaccrual. 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 nonaccrual 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. Loans whose terms are modified are classified as troubled debt restructurings if the borrowers have been granted concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring generally involve a temporary reduction in interest rate or an extension of a loan’s stated maturity date. Nonaccrual troubled debt restructurings are restored to accrual status if principal and interest payments, under the modified terms, are current for nine consecutive months after modification. Loans classified as troubled debt restructurings are designated as impaired. 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. Acquired Loans Loans that Mid Penn acquires in connection with business combinations are recorded at fair value with no carryover of the existing related allowance for loan losses. Fair value of the loans involves estimating the amount and timing of principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Loans acquired with credit deterioration are accounted for under ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality Loans acquired through business combinations that meet the specific criteria of ASC 310-30 are individually evaluated each period to analyze expected cash flows. To the extent that the expected cash flows of a loan have decreased due to credit deterioration, Mid Penn establishes an allowance. Loans acquired through business combinations that do not meet the specific criteria of ASC 310-30 are accounted for under ASC 310-20. These loans are initially recorded at fair value, and include credit and interest rate marks associated with acquisition accounting adjustments. Purchase premiums or discounts are subsequently amortized as an adjustment to yield, using the level yield method, over the estimated contractual lives of the loans. There is no allowance for loan losses established at the acquisition date for acquired performing loans. An allowance for loan losses is recorded for any credit deterioration in these loans subsequent to acquisition. Acquired loans that met the criteria for impaired or nonaccrual of interest prior to the acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if Mid Penn expects to fully collect the new carrying value (i.e. fair value) of the loans. As such, Mid Penn may no longer consider the loan to be nonaccrual or nonperforming at the date of acquisition and may accrue interest on these loans, including the impact of any accretable discount. In addition, charge-offs on such loans would be first applied to the nonaccretable difference portion of the fair value adjustment.
Bank Premises and Equipment	(i) Bank 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.
Bank Premises and Equipment Held For Sale	(j) Bank Premises and Equipment Held For Sale Bank premises and equipment designated as held for sale are carried at the lower of cost or market value. There were no premises and equipment classified as held for sale as of December 31, 2019 or 2018. During 2019, Mid Penn sold the land and facility formerly used as a full-service retail banking property. An impairment charge of $105,000 was recorded during the first quarter of 2019 related to this property and is included in other expenses on the Consolidated Statement of Income.
Leases	(k) Leases Mid Penn leases certain premises and equipment, and as of January 1, 2019, for all leases in effect upon adoption of Accounting Standards Update 2016-02, Leases 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 right-of-use asset. Finance lease expense consists of the amortization of the right-of-use asset, recognized as a component of occupancy expense on the Consolidated Statements of Income, and interest expense on the lease liability, which is recorded as a component of other interest expense 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 (defined as an identified asset by Topic 842) for a period of time in exchange for consideration, and grants Mid Penn the right to both (i) obtain substantially all of the economic benefits from the identified asset’s use, and (ii) 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 (i) lease components, consisting of consideration paid to transfer a good or service to Mid Penn, and (ii) 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. These renewal and extension options were not included in the calculation of the right-of-use assets and lease liabilities as Mid Penn is not reasonably certain that these renewals and extensions will be utilized. 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 right-of-use 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.
Bank Owned Life Insurance	(l) Bank-Owned Life Insurance Mid Penn is the owner and beneficiary of bank-owned life insurance (“BOLI”) policies on current and former Mid Penn directors, as well as BOLI policies acquired through the Phoenix and First Priority acquisitions covering select Miners Bank and First Priority employees. The earnings from the BOLI policies are an asset that can be liquidated, if necessary, with associated tax costs. However, Mid Penn intends to hold these policies and, accordingly, Mid Penn has not provided deferred income taxes on the earnings from the increase in cash surrender value. 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.
Restricted Investments in Bank Stocks	(m) Restricted Investments in Bank Stocks Restricted investments in bank stocks represent required investments in the common stock of correspondent banks. As a member of the FHLB and Atlantic Community Bankers Bank (“ACBB”), the Bank is required to own restricted stock investments in these correspondent banks, which is carried at cost. The level of stock ownership in the FHLB is adjusted by the FHLB throughout the year based upon the level of outstanding borrowings of the Bank (in general, a higher amount of borrowings, requires a higher amount of FHLB stock ownership). During the years ended December 31, 2019, 2018, and 2017 dividends received from the FHLB totaled $424,000, $275,000, and $114,000 respectively.
Income Taxes	(n) Income Taxes Mid Penn accounts for income taxes in accordance with income tax accounting guidance ASC Topic 740, Income Taxes Current income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. Mid Penn determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are reduced by a valuation allowance if, based on the weight of the evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. Mid Penn accounts for uncertain tax positions if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more-likely-than-not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management's judgment. Mid Penn recognizes interest and penalties on income taxes, if any, as a component of income tax expense. In December 2017, the Tax Cuts and Jobs Act (the “TCJA”) was enacted, reducing the corporate tax rate applicable to Mid Penn, for tax years beginning after 2017, to a flat 21 percent statutory federal tax rate. Though the reduced rate will provide tax savings to Mid Penn in future periods after 2017, the reduction resulted in a one-time $1,169,000 write-down of Mid Penn’s deferred tax asset in December 2017, because the deferred tax asset was previously valued based upon the projection of Mid Penn realizing a 34 percent future corporate tax rate benefit. This write-down was included in Mid Penn’s income tax provision for the year ended December 31, 2017, as further discussed in Note 17, Income Taxes,
Goodwill	(o) Goodwill Goodwill is the excess of the purchase price over the fair value of assets acquired in connection with past business acquisitions. The goodwill balance at both December 31, 2019 and December 31, 2018 was comprised of, (i) $39,744,000 related to the July 31, 2018 First Priority acquisition, (ii) $19,178,000 related to the January 8, 2018 Scottdale acquisition and (iii) $3,918,000 recorded as a result of the Phoenix acquisition in 2015. Goodwill is evaluated annually for impairment; however, if certain events occur which indicate goodwill might be impaired between annual tests, goodwill must be tested when such events occur. In making this goodwill potential impairment assessment, Mid Penn considers a number of factors including operating results, business plans, economic projections, anticipated future cash flows, current market data, stock price, etc. There are inherent uncertainties related to these factors and Mid Penn’s judgment in applying them to the analysis of goodwill impairment. Changes in economic and operating conditions could result in goodwill impairment in future periods. Mid Penn did not identify any impairment on its outstanding goodwill from its most recent evaluation, which was performed as of October 31, 2019 using a qualitative analysis. In addition, Mid Penn did not identify any goodwill impairment in either 2018 or 2017 using a similar qualitative analyses.
Core Deposit Intangible	(p) Core Deposit Intangible Core deposit intangible is a measure of the value of consumer demand and savings deposits acquired in business combinations accounted for as purchases. The carrying amount of core deposit intangibles was $5,526,000 and $6,893,000 at December 31, 2019 and 2018, respectively. Amortization expense is reflected in the Consolidated Statements of Income in intangible amortization and was $1,367,000, $1,188,000, and $86,000 for the years 2019, 2018, and 2017, respectively. The core deposit intangible for each respective acquisition (Phoenix in 2015, and Scottdale and First Priority in 2018) is being amortized over a ten-year period staring at the respective acquisition date and using a sum-of-the-year’s digits basis. Core deposit intangibles are subject to impairment testing whenever events or changes in circumstances indicate the need for such evaluation. Mid Penn did not identify any core deposit intangible impairment in either 2019, 2018, or 2017.
Foreclosed Assets Held for Sale	(q) Foreclosed Assets Held for Sale Foreclosed assets held for sale consist primarily of real estate acquired through, or in lieu of, foreclosure in settlement of debt, and are recorded at fair value less cost to sell at the date of transfer, establishing a new cost basis. Any valuation adjustments required at the date of transfer are charged to the allowance for loan losses. Subsequent to acquisition, foreclosed assets are carried at fair value less costs of disposal, based upon periodic evaluations that consider changes in market conditions and development and disposal costs. Operating results from assets acquired in satisfaction of debt, including rental income less operating costs and gains or losses on the sale of, or the periodic evaluation of foreclosed assets, are recorded in noninterest expense. As of December 31, 2019, Mid Penn had $78,000 of residential real estate held in other real estate owned. There was also $84,000 in loans for which formal foreclosure proceedings were in process at December 31, 2019. As of December 31, 2018, Mid Penn had $844,000 of residential real estate held in other real estate owned and $211,000 in loans for which formal foreclosure proceedings were in process.
Mortgage Servicing Rights	(r) Mortgage Servicing Rights Mortgage servicing rights are recognized as assets upon the sale of a mortgage loan. A portion of the cost of the loan is allocated to the servicing right based upon relative fair value. The fair value of servicing rights is based on the present value of estimated future cash flows of mortgages sold, stratified by rate and maturity date. Assumptions that are incorporated in the valuation of servicing rights include assumptions about prepayment speeds on mortgages and the cost to service loans. Servicing rights are reported in core deposit and other intangibles in the Consolidated Balance Sheets and are amortized over the estimated period of future servicing income to be received on the underlying mortgage loans. The carrying amount of mortgage servicing rights was $78,000 and $106,000 at December 31, 2019 and 2018, respectively. Amortization expense is reflected in the Consolidated Statements of Income in intangible amortization and was $28,000, $20,000, and $18,000 for the years 2019, 2018, and 2017, respectively. Servicing rights are evaluated for impairment based upon estimated fair value as compared to unamortized carrying value. No servicing right impairments were identified or recorded for the three year period ended December 31, 2019. The principal balance of loans serviced for others was $12,357,000 and $15,601,000 for December, 31 2019 and 2018, respectively.
Investment in Limited Partnership	(s) 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 $190,000 at December 31, 2019 and $233,000 at December 31, 2018, 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 received $76,000 in low-income housing tax credits for each of the tax years ended December 31, 2018 and December 31, 2017. During the second quarter of 2018, Mid Penn entered into a commitment to purchase a limited partnership interest in a low-income housing project to construct thirty-seven apartments and common amenities in Dauphin County, Pennsylvania. All of the units are intended to qualify 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 $7,579,000, which will be paid in installments over the course of construction of the low-income housing facilities. Each installment payment is conditional upon both Mid Penn’s review and approval of the installment payment certificate and continued compliance with the terms of the original partnership agreement. The project has been conditionally awarded $861,000 in annual LIHTCs by the Pennsylvania Housing Finance Agency, with a total anticipated LIHTC amount of $8,613,000 to be awarded to Mid Penn over the ten year amortization period. Mid Penn’s commitment to initiate investments in the limited partnership interest was conditional upon (i) the review and approval of all closing documents, (ii) an opinion letter for tax counsel to the Partnership that the project qualifies for the LIHTCs, and (iii) review and approval by Mid Penn of other documents it deemed necessary. All such initial conditions were satisfied, and Mid Penn began funding the investment during 2018 and is expected to be fully funded in 2020. As of December 31, 2019, the units were substantially complete and met the occupancy requirements necessary to begin recognizing the related amortization and tax credits using the cost amortization method over a ten year period. The carrying value of Mid Penn’s investment in the limited partnership is reported within other assets on the Consolidated Balance Sheet and totaled $7,249,000 at December 31, 2019 and $1,710,000 at December 31, 2018.
Marketing and Advertising Costs	(t) Marketing and Advertising Costs Marketing and advertising costs are expensed as incurred.
Postretirement and Other Benefit Plans	(u) Postretirement Benefit Plans Mid Penn follows the guidance in ASC Topic 715, Compensation-Retirement Benefits As a result of the acquisition of Scottdale on January 8, 2018, Mid Penn assumed a noncontributory defined benefit pension plan covering certain former employees of Scottdale. Liabilities of $183,000 and $345,000, representing the funded status of the plan, were included in other liabilities as of December 31, 2019 and December 31, 2018, respectively. Additionally, for the years ended December 31, 2019 and December 31, 2018, Mid Penn recognized $34,000 and $737,000, respectively, of settlement gains as a result of certain lump sum payouts to participants of the defined benefit pension plan. The settlement gains were recorded in noninterest income as a component of other income for the years ended December 31, 2019 and December 31, 2018. (v) Other Benefit Plan A funded contributory defined-contribution plan is maintained for substantially all employees. The cost of the Mid Penn defined contribution plan is charged to current operating expenses and is funded annually. During 2018, Mid Penn assumed the 401(k) plans of Scottdale and First Priority and, as of December 31, 2019 and December 31, 2018, these 401(k) plans were managed by Mid Penn’s human resources and trust areas. These 401(k) plans were frozen and no contributions were made to the plans during 2019 and 2018.
Trust Assets and Income	(w) Trust Assets and Income Assets held by the Bank in a fiduciary or agency capacity for customers of the Trust Department are not included in the consolidated financial statements since such items are not assets of the Bank. Trust assets under management totaled $152,492,000 and $125,567,000 at December 31, 2019 and 2018, respectively. 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	(x) Revenue Recognition Mid Penn recognizes revenues when earned based upon (i) contractual terms as transactions occur, or (ii) as related services are provided and collectability is reasonably assured. The largest source of revenue for Mid Penn is interest income, which is primarily recognized on an accrual basis according to a written contract, such as loan and lease agreements or investment securities contracts. Mid Penn earns noninterest income through a variety of financial and transactional services such as trust and wealth management services, deposit account transaction fees, ATM debit card fees, and mortgage banking fees. Revenue is recorded for noninterest income based on the contractual terms for the service or transaction performed. In certain circumstances, noninterest income is reported net of associated expenses. On January 1, 2018, Mid Penn adopted FASB ASU 2014-09, Revenue from Contracts with Customers (Topic 606). Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with the previous accounting guidance under ASC 605.This ASU establishes principles for reporting information about the nature, timing, and uncertainty of revenue and cash flows arising from the entity’s contracts to provide goods and services to customers. ASU 2014-09 applies primarily to transactional-based non-interest income revenue streams and excludes mortgage banking income, earnings from cash surrender value of life insurance, and gains on SBA loans. Mid Penn’s non-interest income revenue streams of income from fiduciary activities, service charges on deposits, ATM debit card interchange income, merchant service fees and certain components of other income are within the scope of Topic 606 and are discussed in greater detail below. Income from Fiduciary Activities Income from fiduciary activities consist of investment management fee income, brokerage transaction fee income, and estate fee income. Investment management fee income consists of advisory fees that are 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. Service Charges on Deposits 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. ATM Debit Card Interchange Income 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. Merchant Services Income Merchant services income is processed through a third party provider with whom Mid Penn has partnered to provide merchant services to its business customers. Fees are charged to merchants to process their debit card transactions, cash advance services, and other related products. Mid Penn receives a percentage of the revenue generated from each joint customer relationship after the third party has collected the fee income from the merchant. Payment is primarily received in the following month. Other Income Certain aspects of other income, such as credit card royalties, check orders, and letter of credit fees, are within the scope of Topic 606. 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. Mid Penn has not recognized any assets from the costs to obtain or fulfill a contract with customers for revenue streams that fall within the guidance of Topic 606.
Comprehensive Income	(y) 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. The components of accumulated other comprehensive income (loss), net of taxes, are as follows: (Dollars in thousands) Unrealized Loss on Securities Defined Plan Liability Accumulated Other Comprehensive Income (Loss) Balance - December 31, 2019 $ (128 ) $ 471 $ 343 Balance - December 31, 2018 $ (3,242 ) $ 864 $ (2,378 )
Restricted Common Stock	(z) Restricted Common Stock On May 6, 2014, Mid Penn shareholders approved the 2014 Restricted Stock Plan (the “Plan”), which authorizes the issuance of awards that shall not exceed, in the aggregate, 100,000 shares of common stock. Awards under the Plan are limited to employees and directors of the Company and the Bank selected by the Compensation Committee of the Board of Directors, to advance the best interest of Mid Penn and its shareholders. Share-based compensation expense relating to restricted stock is recognized on a straight-line basis over the vesting periods of the awards and is a component of salaries and benefits expense. The restricted stock is non-voting and non-participating until the granted shares vest. Once the shares vest, the recipient has full voting rights and is entitled to common stock dividends.
Earning Per Share	Earnings Per Share Basic earnings per share are computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during each of the years presented. Diluted earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding plus common shares that would have been outstanding if dilutive potential common shares, consisting of unvested restricted stock, had been issued. The following data show the amounts used in computing basic and diluted earnings per common share. (Dollars in thousands, except per share data) 2019 2018 2017 Net income $ 17,701 $ 10,596 $ 7,089 Less: Dividends on Series D preferred stock — 102 — Net income available to common shareholders $ 17,701 $ 10,494 $ 7,089 Weighted average shares outstanding (basic) 8,468,586 7,071,091 4,236,616 Effect of dilutive unvested restricted stock grants 23,487 20,706 15,945 Weighted average shares outstanding (diluted) 8,492,073 7,091,797 4,252,561 Basic earnings per common share $ 2.09 $ 1.48 $ 1.67 Diluted earnings per common share $ 2.09 $ 1.48 $ 1.67 There were no antidilutive shares at December 31, 2019, 2018, and 2017.
