Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	The accompanying consolidated financial statements include the accounts of Mid Penn Bancorp, Inc. (“Mid Penn” or the “Company”) and its wholly-owned subsidiary, Mid Penn Bank (the “Bank”). All material intercompany accounts and transactions have been eliminated in consolidation. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Mid Penn believes the information presented is not misleading and the disclosures are adequate. For comparative purposes, the March 31, 2018 and December 31, 2018 balances have been reclassified, when, and if necessary, to conform to the 2019 presentation. Such reclassifications had no impact on net income. The results of operations for interim periods are not necessarily indicative of operating results expected for the full year. 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. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The comparability of the financial condition and results of operations as of and for the three months ended March 31, 2019 and 2018, in general, have been materially impacted by the acquisitions of First Priority Financial Corp. (“First Priority”) on July 31, 2018 and the acquisition of The Scottdale Bank & Trust Company (“Scottdale”) on January 8, 2018. Refer to Note 3, Acquisition of First Priority Financial Corp,. Acquisition of The Scottdale Bank & Trust Company, Mid Penn has evaluated events and transactions occurring subsequent to the balance sheet date of March 31, 2019, for items that should potentially be recognized or disclosed in these consolidated financial statements. The evaluation was conducted through the issuance date of these consolidated financial statements.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) 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. 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. Securities to be held to maturity are carried at amortized cost. For available-for-sale debt securities, realized gains and losses on dispositions are based on the 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 statements of income for the respective period. ASC Topic 320, Investments – Debt and Equity Securities In instances when a determination is made that other-than-temporary impairment exists but the investor 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 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 March 31, 2019 and December 31, 2018 Mid Penn’s equity securities consisted of Community Reinvestment Act funds totaling $498,000 and $492,000, respectively. No equity securities were sold during the three months ended March 31, 2019 or 2018. Loans 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. 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 Loans 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 Loans 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 Loans 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, 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 held in the Bank’s portfolio, the interest rate on the residential mortgage would be increased to compensate for the added portfolio risk. Consumer Loans, Including Home Equity Credits 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 $135,000 at March 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 against 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 either bankruptcy or if there is an amount deemed uncollectible. Because all identified losses are immediately charged off, no portion of the allowance 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 in relevant analyses 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. 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 flow 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 12 months for possible 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 acquired entity’s related allowance for loan losses. The fair value of the acquired 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. The excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loan. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable discount. These loans 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 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. 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 the selling costs 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 estimated 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 March 31, 2019, Mid Penn had $350,000 of residential real estate held in other real estate owned and $213,000 in loans for which formal foreclosure proceedings were in process. 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. 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. Mid Penn has made an accounting policy election to segregate lease and non-lease components in the determination of lease consideration used in the calculation of the right-of-use asset and liability for leases of property. 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

First Priority Financial Corp. [Member]
Acquisition	( 3 ) Acquisition of First Priority Financial Corp. On July 31, 2018, Mid Penn completed its acquisition of First Priority Financial Corp. (“First Priority”), through the merger of First Priority with and into Mid Penn. In connection with this acquisition, 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 First Priority 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 impact on the 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. The acquisition of First Priority resulted in the recognition and recording of intangible assets including $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.

Scottdale Bank and Trust Company [Member]
Acquisition	( 4 ) Acquisition of The Scottdale Bank and Trust Company On January 8, 2018, The Scottdale Bank & Trust Company (“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 impact on the 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. The acquisition of Scottdale resulted in the recognition and recording of intangible assets including goodwill of $19,178,000 and a core deposit intangible of $4,940,000.

Consideration is given to the length of time and the extent to which the fair value of the security has been less than amortized cost as well as the overall financial condition 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. At both March 31, 2019 and December 31, 2018, the majority of available-for-sale securities and held-to-maturity securities in an unrealized loss position were obligations of state and political subdivisions, U.S. Treasury and agency securities, and mortgage-backed U.S. government agencies. Mid Penn had no securities considered by management to be other-than-temporarily impaired as of March 31, 2019, December 31, 2018, or March 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 relate to changes in interest rates, and not erosion of credit quality.

The terms of these forbearance agreements vary and generally involve modifications from the original loan agreements including either a reduction in the amount of principal payments for certain or extended periods, interest rate reductions, and/or the intent for the loan to be repaid as collateral is sold. Mid Penn’s troubled debt restructured loans at March 31, 2019 totaled $2,694,000 and included four loans totaling $510,000 representing accruing impaired loans to unrelated borrowers in compliance with the terms of the modification, with three loans being accruing impaired residential mortgages to unrelated borrowers totaling $509,000 and one loan being an accruing impaired home equity loan of $1,000. The remaining $2,184,000 of troubled debt restructurings was attributable to nine loans among four 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 $1,161,000 of the total $2,184,000 in nonaccrual impaired troubled debt restructured loans. The decrease in the troubled debt restructured loan balance when compared to the December 31, 2018 amount was due to the successful workout during the first quarter of 2019 of one nonaccrual troubled debt restructured loan totaling $4,302,000. 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 modification, 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 were 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. As of December 31, 2018, 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 2018. There were no troubled debt restructured loans added during the three months ended March 31, 2019 or 2018. As a result of management evaluations at March 31, 2019, March 31, 2018, and December 31, 2018, any necessary specific allocations or charge-offs have been taken as appropriate. There were no charge-offs associated with existing troubled debt restructured loan relationships for the three months ended March 31, 2019 or 2018. There were no troubled debt restructured loans that defaulted within twelve months of restructure during the three months ended March 31, 2019 and 2018. The following tables provide activity for the accretable yield of acquired impaired loans from the Phoenix Bancorp, Inc. (March 2015), Scottdale (January 2018), and First Priority (July 2018) acquisitions for the three months ended March 31, 2019 and 2018.

Leases [Abstract]
Leases	(8) Leases On January 1, 2019, Mid Penn adopted ASU No. 2016-02 “Leases” As of the January 1, 2019 adoption date, Mid Penn leased twenty-four branch locations under non-cancelable operating leases, which expire at various dates through the year ending December 31, 2035. Three of Mid Penn’s operating leases are with related parties. 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 and expires February 28, 2039. 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. 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), or equipment leases (deemed immaterial) on the Consolidated Balance Sheet.

Fair Value Measurement

Fair Value Measurement	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurement	( 9 ) 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 during the three months ended March 31, 2019 or 2018. The following tables illustrate the assets measured at fair value on a recurring 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.

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. (c) Includes qualitative adjustments by management and estimated liquidation expenses. Mid Penn uses the following methodologies and assumptions 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 tables): 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 March 31, 2019 and December 31, 2018.

Commitments And Contingencies Disclosure [Abstract]
Guarantees, Commitments and Contingencies	( 10 ) Guarantees, Commitments and Contingencies Guarantees In the normal course of business, Mid Penn makes various commitments and incurs certain contingent liabilities which are not reflected in the accompanying consolidated financial statements. The commitments include various guarantees and commitments to extend credit. 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. Mid Penn evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on management’s credit evaluation of the customer. Standby letters of credit and financial guarantees written are conditional commitments to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Mid Penn had $19,758,000 and $20,839,000 of standby letters of credit outstanding as of March 31, 2019 and December 31, 2018, respectively. Mid Penn does not anticipate any losses because of these transactions. The amount of the liability as of March 31, 2019 and December 31, 2018 for payment under standby letters of credit issued was not material. Commitments During the second quarter of 2018, Mid Penn entered into a commitment to purchase an additional 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 investment in the limited partnership will be reported in other assets on the Consolidated Balance Sheet and will be amortized over a ten year period once the facilities become operational and begin to be occupied. 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. The total investment in the limited partnership was $2,744,000 and $1,710,000 on March 31, 2019 and December 31, 2018, respectively, and was included in the reported balance of other assets on the Consolidated Balance Sheet. Contingencies In a letter dated January 24, 2019, notification was received from the FDIC indicating that Mid Penn was eligible for small bank assessment credits. In general, banks that did not pay surcharges during the credit calculation period, defined as the third quarter of 2016 through the third quarter of 2018, are eligible for small bank assessment credits. Small banks with total consolidated assets of less than $10 billion were awarded assessment credits for the portion of their assessments that contributed to the growth in the reserve ratio from 1.15 percent to 1.35 percent. Each individual bank’s credit share is calculated as the product of the apportioned share of credits to an individual eligible institution multiplied by the total aggregate credits, and the FDIC’s preliminary estimate of Mid Penn’s total assessment credit is $492,000. The small bank assessment credits are contingent on the reserve ratio reaching at least 1.38 percent, which had not occurred as of March 31, 2019. The credit can only be applied against future assessments, is not refundable in cash, and cannot be sold.

Subordinated Debt	(11 ) Subordinated Debt Subordinated Debt Assumed July 2018 with the First Priority Acquisition On July 31, 2018, Mid Penn completed its acquisition of First Priority and assumed $9,500,000 of Subordinated Notes (the “First Priority Notes”). In accordance with purchase accounting principles, the First Priority Notes were assigned a fair value premium of $247,000, which is amortized through interest expense until the maturity date of November 30, 2025. The notes are intended to be treated as Tier 2 capital for regulatory reporting purposes. 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 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 is 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.

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. Holders of the 2017 Notes may not accelerate the maturity of the 2017 Notes, except upon the bankruptcy, insolvency, liquidation, receivership or similar event of Mid Penn or Mid Penn Bank, its principal banking subsidiary. Subordinated Debt Issued December 2015 On December 9, 2015, Mid Penn sold $7,500,000 aggregate principal amount of Subordinated Debt (the “2015 Notes”) due 2025.

New Accounting Pronouncement Or Change In Accounting Principle Retrospective Adjustments [Abstract]
Recent Accounting Pronouncements	(15) Recent Accounting Pronouncements Accounting Standards Adopted in 2019 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, effective 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. As of March 31, 2019, Mid Penn recognized (i) a finance lease ROU asset of $3,582,000 and (ii) a finance lease liability of $3,601,000 included in the reported amount of long-term debt. The adoption of this standard is did not have a material impact on the Consolidated Statements of Income or the Consolidated Statements of Cash Flow. See Note 8 - Leases In March 2019, the FASB issued ASU No. 2019-01, “Leases: Codification Improvements.” ASU 2018-07: The FASB issued ASU 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting The 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 14. 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 Pending Adoption ASU 2016-13 : The FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. 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. The Update has tiered effective dates, with early adoption permitted for all entities as of the fiscal year beginning after December 15, 2018. For public business entities that are SEC filers, the amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. For all other public business entities, the amendments are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. For all other entities, including not-for-profit entities and employee benefit plans within the scope of Topics 960 through 965 on plan accounting, the amendments are effective for fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. 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 has selected a software vendor to support both the implementation of ASU 2016-13 and the ongoing compliance requirements. We have provided our core data to the vendor and completed an assessment of the information to see what, if any, additional data elements may need to be collected to perform the calculation. After all required data elements are collected and loaded into the software, Mid Penn plans to run one quarter of reports based on our current methodology to validate the data flow, and intends to run two quarters under the CECL methodology prior to the adoption of the standard on January 1, 2020. 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 will 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.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2019
Accounting Policies [Abstract]
Investment Securities	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. Securities to be held to maturity are carried at amortized cost. For available-for-sale debt securities, realized gains and losses on dispositions are based on the 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 statements of income for the respective period. ASC Topic 320, Investments – Debt and Equity Securities In instances when a determination is made that other-than-temporary impairment exists but the investor 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	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 March 31, 2019 and December 31, 2018 Mid Penn’s equity securities consisted of Community Reinvestment Act funds totaling $498,000 and $492,000, respectively. No equity securities were sold during the three months ended March 31, 2019 or 2018.
Loans	Loans 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. 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 Loans 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 Loans 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 Loans 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, 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 held in the Bank’s portfolio, the interest rate on the residential mortgage would be increased to compensate for the added portfolio risk. Consumer Loans, Including Home Equity Credits 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	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 $135,000 at March 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 against 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 either bankruptcy or if there is an amount deemed uncollectible. Because all identified losses are immediately charged off, no portion of the allowance 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 in relevant analyses 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. 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 flow 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 12 months for possible 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	Acquired Loans Loans that Mid Penn acquires in connection with business combinations are recorded at fair value with no carryover of the acquired entity’s related allowance for loan losses. The fair value of the acquired 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. The excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loan. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable discount. These loans 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 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.
Foreclosed Assets Held for Sale	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 the selling costs 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 estimated 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 March 31, 2019, Mid Penn had $350,000 of residential real estate held in other real estate owned and $213,000 in loans for which formal foreclosure proceedings were in process. 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.
Leases	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. Mid Penn has made an accounting policy election to segregate lease and non-lease components in the determination of lease consideration used in the calculation of the right-of-use asset and liability for leases of property. 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.
Investment in Limited Partnership	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 $222,000 at March 31, 2019, and $233,000 at December 31, 2018, net of amortization, using the straight-line method. The investment in the limited partnership is reported in other assets on the Consolidated Balance Sheets, and Mid Penn’s maximum exposure to loss is limited to the carrying value of the investment. During the second quarter of 2018, Mid Penn entered into a commitment to purchase an additional 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 investment in the limited partnership will be reported in other assets on the Consolidated Balance Sheet and will be amortized over a ten year period once the facilities become operational and begin to be occupied. 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. The total investment in the limited partnership was $2,744,000 and $1,710,000 on March 31, 2019 and December 31, 2018, respectively, and was included in the reported balance of other assets on the Consolidated Balance Sheet.
Core Deposit Intangible	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 intangible was $6,544,000 and $6,893,000 at March 31, 2019 and December 31, 2018, respectively. Amortization expense is reflected in the Consolidated Statements of Income in intangible amortization and was $348,000 and $245,000 for the three months ended March 31, 2019 and 2018, respectively. The core deposit intangible for each respective acquisition (Phoenix in March 2015; Scottdale in January 2018; and First Priority in July 2018) is being amortized over a ten-year period starting at the respective acquisition date and using a sum-of-the-year’s digits basis. Core deposit intangible assets are subject to impairment testing whenever events or changes in circumstances indicate the need for such evaluation.
Goodwill	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 was the same at both March 31, 2019 and December 31, 2018, and 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 would be tested for impairment when such events occur. In making a potential impairment assessment of goodwill, 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. Mid Penn did not identify any impairment on its outstanding goodwill from its most recent evaluation, which was performed as of October 31, 2018 using a qualitative analysis. Changes in economic and operating conditions could result in goodwill impairment in future periods.
Revenue from Contracts with Customers	Revenue from Contracts with Customers 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 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 typically based on market values of clients’ managed portfolios and transaction fees for fiduciary services performed, both of which are recognized as earned. Brokerage transaction fee income includes advisory fees which are recognized as earned on a monthly basis and transaction fees that are recognized when transactions occur. Payment is typically received in the following month. Estate fee income is recognized as services are performed over the service period, generally eighteen months. 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 most interchange activity is received 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	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 also recognizes other comprehensive income (loss) from 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 Mid Penn recognizes 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 Benefit Plans Accumulated Other Comprehensive Loss Balance - March 31, 2019 $ (1,429 ) $ 858 $ (571 ) Balance - December 31, 2018 $ (3,242 ) $ 864 $ (2,378 )
Earning Per Common Share	Earnings per common share are computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during each of the periods presented. The following data show the amounts used in computing earnings per common share. (Dollars in thousands, except per share data) Three Months Ended March 31, 2019 2018 Net income $ 4,077 $ 1,004 Weighted average common shares outstanding 8,460,002 5,974,949 Basic and diluted earnings per common share $ 0.48 $ 0.17 W eighted average shares outstanding increased for the three months ended March 31, 2019 when compared to the same periods in 2018 primarily as a result of the issuance of 2,320,800 shares of Mid Penn common stock on July 31, 2018 in connection with the First Priority acquisition. There were no dilutive securities impacting the calculation of earnings per share for the periods ended March 31, 2019 and 2018.
