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.

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan and lease losses, the assessment of other-than-temporary impairment of investment securities, the valuation of goodwill and assessment for impairment, and the valuation of assets acquired and liabilities assumed in business combinations.

For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash on hand, balances due from banks, and federal funds sold, all of which mature within ninety days.

The Bank is required by banking regulations to maintain certain minimum cash reserves. As of both December 31, 2020 and 2019, there was no cash reserve balances required to be maintained at the Federal Reserve of Philadelphia because the Bank had sufficient vault cash available.

Interest-bearing time deposits with other financial institutions consist of certificates of deposits in other financial institutions with maturities within one year.

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. Available-for-sale securities are those that management intends to use as part of its asset and liability management strategy and that may be sold in response to liquidity needs, changes in interest rates, resultant prepayment risk, pledging requirements, and other factors related to effective portfolio management. For available-for-sale debt securities, realized gains and losses on dispositions are based on the difference between net proceeds and the amortized cost of the securities sold, using the specific identification method. Unrealized gains and losses on debt securities are based on the difference between the amortized cost and fair value of each security as of the respective reporting date. Unrealized gains and losses are credited or charged to other comprehensive income, whereas realized gains and losses flow through Mid Penn’s consolidated statement of income for the respective period.

Securities to be held to maturity are carried at amortized cost. Unrealized holding gains and losses on held-to-maturity securities are excluded from earnings, and are not a component of accumulated other comprehensive income (loss) within shareholders’ equity.

Premiums and discounts on debt securities are amortized as an adjustment to interest income using the interest method. Realized gains and losses on sales of investment securities are computed on the basis of specific identification of the cost of each security.

ASC Topic 320, Investments – Debt Securities, clarifies the interaction of the factors that should be considered when determining whether a debt security is other-than-temporarily impaired. For debt securities, management must assess, in addition to the credit condition of the underlying issuer, whether (a) it has the intent to sell the security and (b) it is more likely than not that it will be required to sell the security prior to its anticipated recovery. These steps are done before assessing whether the Company will recover the cost basis of the investment.

In instances when a determination is made that an other-than-temporary impairment exists but the Company does not intend to sell the respective 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.

As a result of Mid Penn’s adoption of ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities on January 1, 2018, the Corporation reports its equity securities with readily determinable fair values at fair value on the Consolidated Balance Sheet, with realized and unrealized gains and losses reported in other expense on the Consolidated Statements of Income. Prior to January 1, 2018, equity securities were stated at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income or loss, net of tax. The adoption of ASU 2016-01 on January 1, 2018 resulted in net unrealized losses of $44,000 being reclassified out of accumulated other comprehensive loss and into retained earnings as reflected on the Consolidated Statement of Changes in Shareholders’ Equity for the period ended December 31, 2018.

As of December 31, 2020 and 2019, Mid Penn’s equity securities consisted of Community Reinvestment Act funds totaling $515,000 and $507,000, respectively. An equity security consisting of $1,000,000 of preferred stock of another financial institution was purchased and subsequently sold during the year ended December 31, 2020, resulting in a gain on sale of $6,000. No equity securities were sold during the year ended December 31, 2019.

Mortgage loans originated and intended for sale in the secondary market are included in loans held for sale and are reported at the lower of cost or fair value, as determined by the aggregate commitments from investors or current investor yield requirements. Gains and losses on sales of mortgage loans are included in noninterest income in the Consolidated Statements of Income.

Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at their outstanding unpaid principal balances, net of an allowance for loan losses and any deferred fees or costs. Interest income is accrued on the unpaid principal balance. Residential loans held for sale are carried at fair value and are included in loans held for sale on the balance sheet. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the yield (interest income) of the related loans, generally being amortized over the contractual life of the loan. Premiums and discounts on purchased loans are amortized as adjustments to interest income using the effective yield method.

The loan portfolio is segmented into commercial and consumer loans. Commercial loans consist of the following classes: commercial and industrial, commercial real estate, commercial real estate-construction and lease financing. Consumer loans consist of the following classes: residential mortgage loans, home equity loans and other consumer loans.

For all classes of loans, the accrual of interest generally is discontinued when the contractual payment of principal or interest has become 90 days or more past due, or management has serious doubts about further collectability of principal or interest even though the loan is currently performing. A loan past due 90 days or more may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest is credited to income. Interest received on nonaccrual loans, including impaired loans, is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Nonaccrual loans may be restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time (generally, at least nine consecutive months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The past due status of all classes of loans receivable is determined based on contractual due dates for loan payments.

Mid Penn originates commercial and industrial loans. Most of the Bank’s commercial and industrial loans have been credits 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 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.

Mid Penn offers a wide array of residential mortgage loans for both permanent structures and those under construction. The Bank’s residential mortgage originations are secured primarily by properties located in its primary market and surrounding areas. Residential mortgage loans have terms up to a maximum of 30 years and with loan-to-value ratios up to 100 percent of the lesser of the appraised value of the security property or the contract price. Private mortgage insurance is generally required in an amount sufficient to reduce the Bank’s exposure to at or below the 85 percent loan-to-value level. Residential mortgage loans generally do not include prepayment penalties.

In underwriting residential mortgage loans, the Bank evaluates both the borrower’s ability to make monthly payments and the value of the property securing the loan. Most properties securing real estate loans made by Mid Penn are appraised by independent fee appraisers. The Bank generally requires borrowers to obtain title insurance and fire and property insurance (including flood insurance, if necessary) in an amount not less than the amount of the loan. Real estate loans originated by the Bank generally contain a “due on sale” clause allowing the Bank to declare the unpaid principal balance due and payable upon the sale of the security property.

The Bank underwrites residential mortgage loans to the standards established by the secondary mortgage market, i.e., Fannie Mae, Ginnie Mae, Freddie Mac, Federal Home Loan Bank or Pennsylvania Housing Finance Agency standards, with the intention of selling the majority of residential mortgages originated into the secondary market. In the event that the facts and circumstances surrounding a residential mortgage application do not meet all underwriting conditions of the secondary mortgage market, the Bank will evaluate the failed conditions and evaluate the potential risk of holding the residential mortgage in the Bank’s portfolio rather than rejecting the loan request. In the event that the loan is funded and held in the Bank’s portfolio, the interest rate on the residential mortgage would be increased to compensate for the added portfolio risk.

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.

On March 27, 2020, in response to the novel coronavirus (“COVID-19”) pandemic, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was signed into law by President Donald Trump. This legislation created the federal Paycheck Protection Program (“PPP”) which permitted eligible business entities to apply for loans through a participating financial institution to cover payroll, rent, and other business expenses during the COVID-19 pandemic. The PPP loans, which are 100 percent guaranteed by the Small Business Administration (“SBA”), have up to a five-year term to maturity and carry a low interest rate of 1 percent throughout the loan term. The vast majority of Mid Penn’s PPP loans have a two-year term to maturity. The SBA may forgive the PPP loans if, among other criteria, at least 60 percent of the proceeds are used for payroll costs. Also, the borrowers will not have to make any payments for six months following the date of disbursement of the loan, though interest will continue to accrue during the deferment period. The SBA also provided a processing fee per loan to financial institutions who participated in the PPP, with the amount of such fee ranging from 1 percent to 5 percent as pre-determined by the SBA dependent upon the size of each respective credit. In addition to the processing fees, Mid Penn recorded related loan origination costs. As of December 31, 2020, Mid Penn had received $20,883,000 of nonrefundable loan processing fees related to the loans disbursed as a result of Mid Penn’s participation in the PPP initiative. The balance of these fees that have not yet been realized as income, and the related loan origination costs, are deferred in accordance with ASC 310-20, Receivables—Nonrefundable Fees and Other Costs and will be amortized to interest and fees on loans and leases on the Consolidated Statements of Income over the life of each respective loan. During the year ended December 31, 2020, Mid Penn recognized $13,137,000 of PPP processing fees within interest and fees on loans and leases on the Consolidated Statements of Income.

As of December 31, 2020, Mid Penn had $388,313,000 of net PPP loans outstanding ($396,059,000 of gross PPP loans, net of deferred PPP processing fees of $7,746,000) with all of these loans being recorded in the commercial and industrial loan portfolio classification.

On February 22, 2021, on a Form 8-K filed with the Securities and Exchange Commission (“SEC”), Mid Penn reported that through February 18, 2021 it had received 2021 Paycheck Protection Program (“2021 PPP”) loan funding approvals through the Small Business Administration (“SBA”), and made subsequent loan disbursements, for 2,047 business customers totaling more than $290 million in loans. These businesses collectively employ more than 26,000 individuals. The 2021 PPP application window remains open as of the date of this report, and Mid Penn is continuing to process existing applications for loans that have not yet been approved or disbursed, and is continuing to receive new applications for submission to the SBA for additional PPP loan support of customers. See Note 27, COVID-19 Pandemic Implications, for more details.

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 $66,000 at December 31, 2020 and $80,000 at December 31, 2019.

The allowance is increased by the provision for loan and lease losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectible are charged off to the allowance, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. Non-residential consumer loans are generally charged off no later than 120 days past due on a contractual basis, or earlier in the event of bankruptcy or if there is an amount deemed uncollectible. Because all identified losses are immediately charged off, no portion of the allowance for loan and lease losses is restricted to any individual loan or groups of loans, and the entire allowance is available to absorb any and all loan losses.

The allowance is maintained at a level considered by management to be adequate to provide for losses that can be reasonably anticipated. Management performs a monthly evaluation of the adequacy of the allowance. The allowance is based on Mid Penn’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions, and other relevant factors. This evaluation is inherently subjective, as it requires material estimates that may be susceptible to significant revision as more information becomes available.

The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired. For loans that are classified as impaired, an allowance is established when the discounted cash flows, collateral value, or observable market price of the impaired loan is lower than the carrying value of that loan.

The general component covers pools of loans by loan class including commercial loans not considered impaired, as well as smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these categories of loans, adjusted for qualitative factors. These qualitative risk factors include changes in economic conditions, fluctuations in loan quality measures, changes in collateral values, changes in the experience of the lending staff and loan review systems, changes in lending policies and procedures (including underwriting standards), changes in the mix and volume of loans originated, the effect of other external factors, such as competition and legal and regulatory requirements on the level of estimated credit losses in the existing loan portfolio, shifting industry or portfolio concentrations, and other relevant factors.

Each factor is assigned a value to reflect improving, stable or declining conditions based on management’s best judgment using relevant information available at the time of the evaluation. Adjustments to the factors are supported through documentation of changes in conditions and a narrative accompanying the allowance for loan loss calculation.

The unallocated component of the allowance for loan and lease losses covers several considerations that are not specifically measurable 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, including but not limited to (i) the unknown long-term impact of the ongoing COVID-19 pandemic which may not be reflected in current portfolio performance, (ii) unpredictable changes in economic growth or business conditions in our markets or for certain industries in which we have commercial loan borrowers, or (iii) unanticipated stresses to the values of real estate held as collateral. Any or all of these additional issues can adversely affect our borrowers’ ability to timely repay their loans. Additionally, we have experienced continued strong commercial loan growth, including growth in newer markets where we have less of a loss history. Also, the unallocated component allocation recognizes the inherent imprecision in our allowance for loan and lease loss methodology, or any alternative methodology, for estimating specific and general loan losses, including the unpredictable timing and amounts of charge-offs, the fact that historical loss averages don’t necessarily correlate to future loss trends, and unexpected changes to specific-credit or general portfolio future cash flows and collateral values which could negatively impact unimpaired portfolio loss factors.

Mid Penn generally considers a commercial loan (consisting of commercial and industrial, commercial real estate, commercial real estate-construction, and lease financing loan classes) to be impaired when it becomes 90 days or more past due and not in the process of collection, or sooner when it is probable that Mid Penn will be unable to collect all contractual principal and interest due. This methodology assumes the borrower cannot or will not continue to make additional payments. At that time, the loan would generally be considered collateral dependent as the discounted cash flows method would generally indicate no operating income available for evaluating the collateral position; therefore, most impaired loans are deemed to be collateral dependent.

In addition, Mid Penn’s rating system assumes any loans classified as nonaccrual, included in the substandard rating, to be impaired, and most of these loans are considered collateral dependent; therefore, most of Mid Penn’s impaired loans, whether reporting a specific allocation or not, are considered collateral dependent.

Mid Penn evaluates loans for charge-off on a monthly basis. Policies that govern the recommendation for charge-off are unique to the type of loan being considered. Commercial loans classified as substandard nonaccrual, doubtful, having probable loss will first have a collateral evaluation completed in accordance with the guidance on impaired loans. Once the collateral evaluation has been completed, a specific allocation of allowance is made based upon the results of the evaluation. The remaining balance remains a nonperforming loan with the original terms and interest rate intact (not restructured). In the event the loan is unsecured, the loan would have been charged-off at the recognition of impairment. Commercial real estate loans determined to be impaired will also have an initial collateral evaluation completed in accordance with the guidance on impaired loans. An updated real estate valuation is ordered and the collateral evaluation is modified to reflect any variations in value. A specific allocation of allowance is made for any anticipated collateral shortfall. The remaining balance remains a nonperforming loan with the original terms and interest rate intact (not restructured). The process of charging off a residential mortgage loan begins when a loan becomes delinquent for 90 days and is not in the process of collection. The existing appraisal is reviewed and a lien search is obtained to determine lien position and any instances of intervening liens. A new appraisal of the property will be ordered if deemed necessary by management, and a collateral evaluation is completed. The loan will then be charged down to the value indicated in the evaluation. Non-residential consumer loans are generally charged off no later than 120 days past due on a contractual basis, or earlier in the event of either bankruptcy or if there is an amount deemed uncollectible. The collateral shortfall of the consumer loan is recommended for charge-off at this point.

As noted above, Mid Penn assesses a specific allocation for commercial loans and commercial real estate loans. The remaining balance remains a nonperforming loan with the original terms and interest rate intact (not restructured). In addition, Mid Penn takes a preemptive step when any commercial loan becomes classified under its internal classification system. A preliminary collateral evaluation, in accordance with the guidance on impaired loans, is prepared using the existing collateral information in the loan file. This process allows Mid Penn to review both the credit and documentation files to determine the status of the information needed to make a collateral evaluation. This collateral evaluation is preliminary, but allows Mid Penn to determine if any potential collateral shortfalls exist.

It is Mid Penn’s policy to obtain updated third-party collateral valuations on all impaired loans secured by real estate as soon as practically possible following the credit being classified as substandard nonaccrual. Prior to receipt of the updated real estate valuation, Mid Penn will use any existing real estate valuation to determine any potential allowance issues; however, no allowance recommendation will be made until such time Mid Penn is in receipt of the updated valuation. The Asset Recovery department employs an electronic tracking system to monitor the receipt of and need for updated appraisals. To date, there have been no material time lapses noted with the above processes.

In some instances, Mid Penn is not holding real estate as collateral and is relying on business assets (personal property) for repayment. In these circumstances, a collateral inspection is performed by Mid Penn personnel to determine an estimated value. The value is based on net book value, as provided by the financial statements, and discounted accordingly based on determinations made by management. Occasionally, Mid Penn will employ an outside service to provide a fair estimate of value based on auction sales or private sales. Management reviews the estimates of these third parties and discounts them accordingly based on management’s judgment, if deemed necessary.

For impaired loans with no valuation allowance required, the independent third party market valuations on the subject property obtained by Mid Penn as soon as practically possible following the credit being placed on nonaccrual status sometimes indicates that the loan-to-value ratio is sufficient to obviate the need for a specific allocation in spite of significant deterioration in real estate values in Mid Penn’s primary market area. These circumstances are determined on a case by case analysis of the impaired loans.

Mid Penn actively monitors the values of collateral on impaired loans. This monitoring may require the modification of collateral values over time or changing circumstances by some factor, either positive or negative, from the original values. All collateral values will be assessed by management at least every twelve months for revaluation by an independent third party.

Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, Mid Penn does not separately identify individual residential mortgage loans, home equity loans and other consumer loans for impairment disclosures, unless such loans are the subject of a troubled debt restructuring agreement.

Loans whose terms are modified are classified as troubled debt restructurings if the borrowers have been granted concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring generally involve a temporary reduction in interest rate or an extension of a loan’s stated maturity date. Nonaccrual troubled debt restructurings are restored to accrual status if principal and interest payments, under the modified terms, are current for nine consecutive months after modification. Loans classified as troubled debt restructurings are designated as impaired.

The allowance calculation methodology includes segregation of loan classes into risk rating categories. The borrower’s overall financial condition, repayment sources, guarantors, and value of collateral, if appropriate, are evaluated annually for commercial loans or when credit deficiencies arise, such as delinquent loan payments. Credit quality risk ratings include regulatory classifications of special mention, substandard, doubtful, and loss. Loans criticized as special mention have potential weaknesses that deserve management’s close attention. If uncorrected, the potential weaknesses may result in deterioration of the repayment prospects. Loans classified substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They include loans that are inadequately protected by the current sound net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified doubtful have all the weaknesses inherent in loans classified substandard with the added characteristic that collection or liquidation in full, on the basis of current conditions and facts, is highly improbable. Loans classified as a loss are considered uncollectible and are charged to the allowance for loan losses. Any loans not classified as noted above are rated pass.

In addition, federal and state regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance and may require the Bank to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to management. Based on management’s comprehensive analysis of the loan portfolio, management believes the current level of the allowance for loan losses is adequate.

As of December 31, 2020, Mid Penn had $388,313,000 of PPP loans outstanding, net of deferred fees, which are guaranteed by the Small Business Administration and, thus, have no loss reserve allocated to that pool.

Loans that Mid Penn acquires in connection with business combinations are recorded at fair value with no carryover of predecessor institutions’ related allowance for loan losses. The balance of loans acquired at fair value and included in the balance of loans and leases, net of unearned interest on the Consolidated Balance Sheets totaled $276,701,000 and $414,498,000 as of December 31, 2020 and December 31, 2019, respectively. Determining the fair value of 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.

Loans acquired with credit deterioration are accounted for under ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. For these loans, 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. The nonaccretable discount includes estimated future credit losses expected to be incurred over the life of the loan. Subsequent decreases to the expected cash flows will require Mid Penn to evaluate the need for an additional allowance. Subsequent improvement in expected cash flows will result in the reversal of a corresponding amount of the nonaccretable discount which Mid Penn will then reclassify as accretable discount that will be recognized into interest income over the remaining life of the loan.

Loans acquired through business combinations that meet the specific criteria of ASC 310-30 are individually evaluated each period to analyze expected cash flows. To the extent that the expected cash flows of a loan have decreased due to credit deterioration, Mid Penn establishes an allowance.

Loans acquired through business combinations that do not meet the specific criteria of ASC 310-30 are accounted for under ASC 310-20. These loans are initially recorded at fair value, and include credit and interest rate marks associated with acquisition accounting adjustments. Purchase premiums or discounts are subsequently amortized as an adjustment to yield, using the level yield method, over the estimated contractual lives of the loans. There is no allowance for loan losses established at the acquisition date for acquired performing loans. An allowance for loan losses is recorded for any credit deterioration in these loans subsequent to acquisition.

Acquired loans that met the criteria for impaired or nonaccrual of interest prior to the acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if Mid Penn expects to fully collect the new carrying value (i.e. fair value) of the loans established at the time of acquisition. 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.

Beginning during the second quarter of 2020, Mid Penn entered into loan-level interest rate swaps (“swaps”) to facilitate certain customer transactions and meet their financing needs. These swaps qualify as derivatives, but are not designated as hedging instruments. A loan-level interest rate swap is a contract in which the series of interest rate flows (fixed and variable) are exchanged over the term of a loan with certain qualifying commercial loan customers, and Mid Penn simultaneously enters into an interest rate swap with a dealer counterparty with identical notional amounts and terms. The net result of these swaps is that the customer pays a fixed interest rate and Mid Penn receives a floating interest rate. The swap positions with customers are equally offset with the dealer counterparties to minimize the potential impact on Mid Penn’s financial statements.

Pursuant to our agreements with the dealer counterparties, we may receive collateral or may be required to post collateral based upon mark-to-market positions. Beyond unsecured threshold levels, collateral in the form of cash or securities may be made available to counterparties of interest rate swap transactions. Based upon our current positions and related future collateral requirements relating to them, we believe any effect on our cash flow or liquidity position to be immaterial.

Derivatives contain an element of credit risk, including the possibility that we will incur a loss because a party to the agreements, which may be a dealer counterparty or a customer, fails to meet its contractual obligations. Derivative contracts may only be executed with dealer counterparties as approved by our Board of Directors. Similarly, derivatives with customers may only be executed with customers within credit exposure limits as approved by our Board of Directors. Loan-level interest rate swaps are considered derivatives but are not accounted for using hedge accounting.

Land is carried at cost. Buildings, furniture, fixtures, equipment, land improvements, and leasehold improvements are stated at cost less accumulated depreciation. Depreciation is computed by the straight-line method over the estimated useful lives of the assets. Building assets are depreciated using an estimated useful life of five to fifty years. Furniture, fixtures, and equipment are depreciated using an estimated useful life of three to ten years. Land improvements are depreciated over an estimated useful life of ten to twenty years. Leasehold improvements are depreciated using an estimated useful life that is the lesser of the remaining life of the lease or ten to fifteen years. Maintenance and normal repairs are charged to expense when incurred, while major additions and improvements are capitalized. Gains and losses on disposals are reflected in current operations.

Bank premises and equipment designated as held for sale are carried at the lower of cost or market value, and, at December 31, 2020, totaled $210,000 related to a retail banking property which was closed and listed for sale on December 31, 2020. There were no premises and equipment classified as held for sale as of December 31, 2019. During 2019, Mid Penn sold the land and facility formerly used as a full-service retail banking property. An impairment charge of $105,000 was recorded during the year ended December 31, 2019 related to this property and is included in other expenses on the Consolidated Statement of Income. There were no impairment charges recorded during the year ended December 31, 2020.

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 (Topic 842), as well as any leases commencing thereafter, Mid Penn has recognized a right-of-use asset and a related lease liability for each distinct lease agreement. The lease right-of-use asset consists of the amount of the initial measurement of the lease liability, adjusted for (i) any lease payments made to the lessor at or before the commencement date, minus any lease incentives received, and (ii) any initial direct costs incurred by the lessee (defined as costs of a lease that would not have been incurred had the lease not been executed). The related lease liability is equal to the present value of the future lease payments, discounted using the rate implicit in the lease (or if that rate cannot be readily determined, the lessee’s incremental borrowing rate). Given that the rate implicit in the lease is rarely available, all lease liability amounts were calculated using Mid Penn’s incremental borrowing rate at lease inception, on a collateralized basis, for a similar term. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used.

Operating lease expense, recognized as a component of occupancy expense on the Consolidated Statements of Income, consists of a single lease cost calculated so that the remaining cost of the lease is allocated over the remaining lease term on a straight-line basis. Operating lease expense also includes variable lease payments not included in the lease liability, and any impairment of the right-of-use asset. Finance lease expense consists of the amortization of the right-of-use asset, recognized as a component of occupancy expense on the Consolidated Statements of Income, and interest expense on the lease liability, which is recorded as a component of other interest expense on the Consolidated Statements of Income

In assessing whether a contract contains a lease, Mid Penn reviews third-party agreements to determine if the contract conveys the right to control the use of identified property, plant, or equipment (defined as an identified asset by Topic 842) for a period of time in exchange for consideration, and grants Mid Penn the right to both (i) obtain substantially all of the economic benefits from the identified asset’s use, and (ii) direct the use of the identified asset throughout the term of the agreement.

Upon identification that a lease agreement exists, Mid Penn performs an assessment of the consideration to be paid related to the identified asset and quantifies both the (i) lease components, consisting of consideration paid to transfer a good or service to Mid Penn, and (ii) non-lease components, consisting of consideration paid for distinct elements of the contract that are not related to securing the use of the leased asset, such as property taxes, common area maintenance, utilities, and insurance.

Many of Mid Penn’s lease agreements include options to extend or renew contracts subsequent to the expiration of the initial lease term. These renewal and extension options were not included in the calculation of the right-of-use assets and lease liabilities as Mid Penn is not reasonably certain that these renewals and extensions will be utilized. Additionally, for leases that contain escalation clauses related to consumer or other price indices, Mid Penn includes the known lease payment amount as of the commencement date in the calculation of right-of-use assets and related lease liabilities. Subsequent increases in rental payments over the known amount at the commencement date due to increase in the indices will be expensed as incurred.

None of Mid Penn’s lease agreements include residual value guarantees or material variable lease payments. Mid Penn does not have material restrictions or covenants imposed by leases that would impact Mid Penn’s ability to pay dividends or cause Mid Penn to incur additional financial obligations.

Mid Penn is the owner and beneficiary of bank-owned life insurance (“BOLI”) policies on current and former Mid Penn directors, as well as BOLI policies acquired through the Phoenix and First Priority acquisitions covering certain former Miners Bank and First Priority Financial Corp. employees. The earnings from the BOLI policies are an asset that can be liquidated, if necessary, with associated tax costs. However, Mid Penn intends to hold these policies and, accordingly, Mid Penn has not provided deferred income taxes on the earnings from the increase in cash surrender value.

Mid Penn is also party to certain Split-Dollar Life Insurance Arrangements, and in accordance with GAAP, has accrued a liability related to the postretirement benefits covered by an endorsement split-dollar life insurance arrangement, and a liability for the future death benefit.

Restricted investments in bank stocks represent required investments in the common stock of correspondent banks. As a member of the FHLB and Atlantic Community Bankers Bank (“ACBB”), the Bank is required to own restricted stock investments in these correspondent banks, which is carried at cost. The level of stock ownership in the FHLB is adjusted by the FHLB throughout the year based upon the level of outstanding borrowings of the Bank (in general, a higher amount of borrowings, requires a higher amount of FHLB stock ownership). During the years ended December 31, 2020, 2019, and 2018 dividends received from the FHLB totaled $360,000, $424,000, and $275,000 respectively.

Mid Penn accounts for income taxes in accordance with income tax accounting guidance ASC Topic 740, Income Taxes.

Current income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. Mid Penn determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur.

Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are reduced by a valuation allowance if, based on the weight of the evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.

Mid Penn accounts for uncertain tax positions if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more-likely-than-not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management's judgment.

Mid Penn recognizes interest and penalties on income taxes, if any, as a component of income tax expense.

In December 2017, the Tax Cuts and Jobs Act (the “TCJA”) was enacted, reducing the corporate tax rate applicable to Mid Penn, for tax years beginning after 2017, to a flat 21 percent statutory federal tax rate, which remains the applicable statutory federal tax rate through December 31, 2020.

Goodwill is the excess of the purchase price over the fair value of assets acquired in connection with past business acquisitions. The goodwill balance totaled $62,840,000 at both December 31, 2020 and December 31, 2019 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 must be tested when such events occur. In making this goodwill potential impairment assessment, Mid Penn considers a number of factors including operating results, business plans, economic projections, anticipated future cash flows, current market data, stock price, etc. There are inherent uncertainties related to these factors and Mid Penn’s judgment in applying them to the analysis of goodwill impairment. Changes in economic and operating conditions could result in goodwill impairment in future periods.

In support of its March 31, 2020 financial reports, Mid Penn management performed a “Step One” goodwill analysis to determine whether the current or expected impact from the COVID-19 global pandemic resulted in any impairment to the recorded value of its goodwill intangible asset. Based upon this goodwill analysis, Mid Penn management determined that there was no impairment to its goodwill as a result of the COVID-19 pandemic. Additionally, Mid Penn did not identify any impairment on its outstanding goodwill from its most recent annual evaluation, which was performed as of October 31, 2020 using a qualitative analysis. Similar qualitative analyses were performed in 2019 and 2018 with no goodwill impairment recognized.

Core deposit intangible is a measure of the value of consumer demand and savings deposits acquired in business combinations accounted for as purchases. The carrying amount of core deposit intangibles was $4,311,000 and $5,526,000 at December 31, 2020 and 2019, respectively. Amortization expense is reflected in the Consolidated Statements of Income in intangible amortization and was $1,215,000, $1,367,000, and $1,188,000 for the years 2020, 2019, and 2018, respectively. The core deposit intangible for each respective acquisition (Phoenix in 2015, and Scottdale and First Priority in 2018) is being amortized over a ten-year period staring at the respective acquisition date and using a sum-of-the-year’s digits basis. Core deposit intangibles are subject to impairment testing whenever events or changes in circumstances indicate the need for such evaluation. During 2020 and continuing through the period subsequent to December 31, 2020, the novel coronavirus (“COVID-19”) global pandemic has impacted the United States including the State of Pennsylvania and Mid Penn’s market area and communities and customers. Accordingly, Mid Penn management evaluated whether this COVID-19 event resulted in any impairment to the value of its acquired consumer demand and savings deposit base. Management’s determination was that there was no impairment to its core deposit intangible to date as a result of the pandemic or related factors. Supporting this assertion, as reflected in the Consolidated Balance Sheets as of December 31, 2020 and December 31, 2019, Mid Penn has recognized substantial total deposit growth of $562,186,000 or over 29 percent during 2020, with none of this growth attributable to brokered deposits. Subsequent to December 31, 2020, and through the date of this filing, these increased deposit levels were sustained and continued to reflect no evidence of impairment. Mid Penn did not identify any core deposit intangible impairment in either 2019 or 2018.

Foreclosed assets held for sale consist primarily of real estate acquired through, or in lieu of, foreclosure in settlement of debt, and are recorded at fair value less cost to sell at the date of transfer, establishing a new cost basis. Any valuation adjustments required at the date of transfer are charged to the allowance for loan losses. Subsequent to acquisition, foreclosed assets are carried at fair value less costs of disposal, based upon periodic evaluations that consider changes in market conditions and development and disposal costs. Operating results from assets acquired in satisfaction of debt, including rental income less operating costs and gains or losses on the sale of, or the periodic evaluation of foreclosed assets, are recorded in noninterest expense. As of December 31, 2020, Mid Penn had $134,000 of residential real estate held in other real estate owned. There was also $13,000 in loans for which formal foreclosure proceedings were in process at December 31, 2020. As of December 31, 2019, Mid Penn had $78,000 of residential real estate held in other real estate owned and $84,000 in loans for which formal foreclosure proceedings were in process.

Mortgage servicing rights are recognized as assets upon the sale of a mortgage loan. A portion of the cost of the loan is allocated to the servicing right based upon relative fair value. The fair value of servicing rights is based on the present value of estimated future cash flows of mortgages sold, stratified by rate and maturity date. Assumptions that are incorporated in the valuation of servicing rights include assumptions about prepayment speeds on mortgages and the cost to service loans. Servicing rights are reported in core deposit and other intangibles in the Consolidated Balance Sheets and are amortized over the estimated period of future servicing income to be received on the underlying mortgage loans. The carrying amount of mortgage servicing rights was $49,000 and $78,000 at December 31, 2020 and 2019, respectively. Amortization expense is reflected in the Consolidated Statements of Income in intangible amortization and was $29,000, $28,000, and $20,000 for the years 2020, 2019, and 2018, respectively. Servicing rights are evaluated for impairment based upon estimated fair value as compared to unamortized carrying value. No servicing right impairments were identified or recorded for the three-year period ended December 31, 2020. The principal balance of loans serviced for others was $9,384,000 and $12,357,000 for December, 31 2020 and 2019, respectively.

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 $146,000 at December 31, 2020 and $190,000 at December 31, 2019, net of amortization, using the straight-line method and is reported in other assets on the Consolidated Balance Sheets. Mid Penn’s maximum exposure to loss is limited to the carrying value of its investment. Mid Penn received $31,000 in low-income housing tax credits for the tax year ended December 31, 2019, and $76,000 for the tax year ended December 31, 2018.

Mid Penn also owns a limited partnership interest in a low-income housing project to construct thirty-seven apartments and common amenities in Dauphin County, Pennsylvania. The total investment in this limited partnership, net of amortization, was $6,682,000 and $7,249,000 on December 31, 2020 and December 31, 2019, respectively, and was included in the reported balance of other assets on the Consolidated Balance Sheet. All of the units qualified for Federal Low-Income Housing Tax Credits (“LIHTCs”) as provided for in Section 42 of the Internal Revenue Code of 1986, as amended. Mid Penn’s limited partner capital contribution commitment is $7,579,000. Investments made to date, and any future payments under this commitment, are paid in installments over the course of the construction and completion phases 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 is reported in other assets on the Consolidated Balance Sheet and is being amortized over a ten-year period, as the facilities became operational and began to be occupied beginning in December 2019. The project has been conditionally awarded $8,613,000 in total LIHTCs by the Pennsylvania Housing Finance Agency, with an annual LIHTC amount of approximately $861,000 to be awarded to Mid Penn in the year-ended December 31, 2020 and each full year thereafter during the ten-year amortization period. Mid Penn’s commitment to initiate investments in the limited partnership interest was conditional upon (i) the review and approval of all closing documents, (ii) an opinion letter for tax counsel to the Partnership that the project qualifies for the LIHTCs, and (iii) review and approval by Mid Penn of other documents it deemed necessary. All such initial conditions were satisfied and Mid Penn began funding the investment during 2018, and the investment is expected to be fully funded during 2021. Similar to the recognition period of the tax credits, Mid Penn intends to amortize this low-income housing investment using the cost amortization method over a ten-year period.

Mid Penn follows the guidance in ASC Topic 715, Compensation-Retirement Benefits, related to postretirement benefit plans. This guidance requires additional disclosures about defined benefit pension plans and other postretirement defined benefit plans.

As a result of the acquisition of Scottdale on January 8, 2018, Mid Penn assumed a noncontributory defined benefit pension plan covering certain former employees of Scottdale. Liabilities of $461,000 and $183,000, representing the funded status of the plan, were included in other liabilities as of December 31, 2020 and December 31, 2019, respectively. Additionally, for the years ended December 31, 2020 and December 31, 2019, Mid Penn recognized $3,000 and $34,000, respectively, of settlement gains as a result of certain lump sum payouts to participants of the defined benefit pension plan. The settlement gains were recorded in noninterest income as a component of other income for the years ended December 31, 2020 and December 31, 2019.

A funded contributory defined-contribution plan is maintained for substantially all employees. The cost of the Mid Penn defined contribution plan is charged to current operating expenses and is funded annually.

During 2018, Mid Penn assumed the 401(k) plans of Scottdale and First Priority. During the year ended December 31, 2020, the First Priority plan was terminated, and all remaining assets were either transferred to the Mid Penn 401(k) Plan or distributed to former employee participants. The Scottdale 401(k) Plan continues to be managed by Mid Penn’s human resources and trust areas; however, since the January 2018 Scottdale acquisition, the plan has been frozen resulting in no new participants added and no further contributions being made to the plans for the period subsequent to the acquisition through December 31, 2020.

Assets held by the Bank in a fiduciary or agency capacity for customers of the Trust Department are not included in the consolidated financial statements since such items are not assets of the Bank. Trust assets under management totaled $148,621,000 and $152,492,000 at December 31, 2020 and 2019, respectively. Most trust income is recognized on the cash basis, which is not materially different than if it were reported on the accrual basis.

Mid Penn recognizes revenues when earned based upon (i) contractual terms as transactions occur, or (ii) as related services are provided and collectability is reasonably assured. The largest source of revenue for Mid Penn is interest income, which is primarily recognized on an accrual basis according to a written contract, such as loan and lease agreements or investment securities contracts. Mid Penn earns noninterest income through a variety of financial and transactional services such as trust and wealth management services, deposit account transaction fees, ATM debit card fees, and mortgage banking fees. Revenue is recorded for noninterest income based on the contractual terms for the service or transaction performed. In certain circumstances, noninterest income is reported net of associated expenses.

On January 1, 2018, Mid Penn adopted FASB ASU 2014-09, Revenue from Contracts with Customers (Topic 606). Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with the previous accounting guidance under ASC 605.This ASU establishes principles for reporting information about the nature, timing, and uncertainty of revenue and cash flows arising from the entity’s contracts to provide goods and services to customers. ASU 2014-09 applies primarily to transactional-based non-interest income revenue streams and excludes mortgage banking income, earnings from cash surrender value of life insurance, and gains on SBA loans.

Mid Penn’s non-interest income revenue streams of income from fiduciary and wealth management 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 and wealth management activities consist of trust, wealth management, and investment management fee income, brokerage transaction fee income, and estate fee income. Trust, wealth management, and investment management fee income consists of advisory fees that are typically based on market values of clients’ managed portfolios and transaction fees for fiduciary services performed, both of which are recognized as earned. Brokerage transaction fee income includes advisory fees, which are recognized as earned on a monthly basis and transaction fees that are recognized when transactions occur. Payment is typically received in the following month. Estate fee income is recognized as services are performed over the service period, generally eighteen months.

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 consists interchange fees earned when Mid Penn’s debit cards are processed through card payments networks. The interchange fee is calculated as a percentage of the total electronic funds transfer (EFT) transaction plus a per-transaction fee, which varies based on the type of card used, the method used to process the EFT transaction, and the type of business at which the transaction was processed. Revenue is recognized daily as transactions occur and interchange fees are subsequently processed. Payment for interchange activity is received primarily daily, while some fees are aggregated and payment is received in the following month.

Merchant services income 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.

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 consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes changes in unrealized gains and losses on securities available for sale arising during the period and reclassification adjustments for realized gains and losses on securities available for sale included in net income. Mid Penn has an unfunded noncontributory defined benefit plan for directors and other postretirement benefit plans covering full-time employees. These plans utilize assumptions and methods to calculate the fair value of plan assets and recognizing the overfunded and underfunded status of the plans on its consolidated balance sheet. Gains and losses, prior service costs and credits are recognized in other comprehensive income (loss), net of tax, until they are amortized, or immediately upon curtailment.

The components of accumulated other comprehensive income (loss), net of taxes, are as follows:

On May 6, 2014, Mid Penn shareholders approved the 2014 Restricted Stock Plan (the “Plan”), which authorizes the issuance of awards that shall not exceed, in the aggregate, 100,000 shares of common stock. At the August 26, 2020 annual shareholder meeting, Mid Penn shareholders approved an amendment to the Plan to increase the number of shares of common stock authorized for issuance from 100,000 shares to 200,000 shares. Awards under the Plan are limited to employees and directors of the Company and the Bank selected by the Compensation Committee of the Board of Directors, to advance the best interest of Mid Penn and its shareholders.

Share-based compensation expense relating to restricted stock is recognized on a straight-line basis over the vesting periods of the awards and is a component of salaries and benefits expense. The restricted stock is non-voting and non-participating until the granted shares vest. Once the shares vest, the recipient has full voting rights and is entitled to common stock dividends.

Basic earnings per share are computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during each of the years presented. Diluted earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding plus common shares that would have been outstanding if dilutive potential common shares, consisting of unvested restricted stock, had been issued.

The following data show the amounts used in computing basic and diluted earnings per common share.
