SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations ACNB Corporation (the Corporation or ACNB), headquartered in Gettysburg, Pennsylvania, provides banking, insurance, and financial services to businesses and consumers through its wholly-owned subsidiaries, ACNB Bank (Bank) and Russell Insurance Group, Inc. (RIG). The Bank engages in full-service commercial and consumer banking and wealth management services, including trust and retail brokerage, through its twenty-two community banking office locations in Adams, Cumberland, Franklin, and York Counties, Pennsylvania. There are also loan production offices situated in Lancaster and York, Pennsylvania, and Hunt Valley, Maryland. RIG is a full-service insurance agency based in Westminster, Maryland, with additional locations in Germantown and Jarrettsville, Maryland. The agency offers a broad range of property and casualty and group life and health insurance to both individual and commercial clients. On July 1, 2017, ACNB completed its acquisition of New Windsor Bancorp, Inc. (New Windsor) of Taneytown, Maryland. At the effective time of the acquisition, New Windsor merged with and into a wholly-owned subsidiary of ACNB, immediately followed by the merger of New Windsor State Bank (NWSB) with and into ACNB Bank. ACNB Bank now operates in the Maryland market as “NWSB Bank, A Division of ACNB Bank” and serves its marketplace with banking and wealth management services via a network of seven community banking offices located in Carroll County, Maryland. Effective January 11, 2020, ACNB completed its acquisition of Frederick County Bancorp, Inc. (FCBI) and its wholly-owned subsidiary, Frederick County Bank, headquartered in Frederick, Maryland. FCBI was merged with and into a wholly-owned subsidiary of ACNB Corporation immediately followed by the merger of Frederick County Bank with and into ACNB Bank. ACNB Bank will operate in the Frederick County, Maryland, market as “FCB Bank, A Division of ACNB Bank”. Under the terms of the Reorganization Agreement, FCBI stockholders received 0.9900 share of ACNB Corporation common stock for each share of FCBI common stock that they owned as of the closing date. As a result, ACNB Corporation issued 1,590,547 shares of its common stock and cash in exchange for fractional shares based upon $36.43, the determined market share price of ACNB Corporation common stock in accordance with the Reorganization Agreement. One director from FCBI will join the boards of directors of ACNB and ACNB Bank, respectively. With the combination of the two organizations, ACNB Corporation, on a consolidated basis, has approximately $2.2 billion in assets, $1.8 billion in deposits, and $1.6 billion in loans with 34 community banking offices and three loan offices located in the counties of Adams, Cumberland, Franklin, Lancaster and York in Pennsylvania, and the counties of Baltimore, Carroll and Frederick in Maryland. Further discussion of the risk factors involved with the merger of FCBI into the Corporation can be found in Part I, Item 1A–Risk Factors. The Corporation’s primary sources of revenue are interest income on loans and investment securities and fee income on its products and services. Expenses consist of interest expense on deposits and borrowed funds, provisions for loan losses, and other operating expenses. Basis of Financial Statements The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (US GAAP) and include the accounts of the Corporation and its wholly-owned subsidiaries. All significant intercompany transactions have been eliminated. Assets held by the Corporation’s Wealth Management Department, including trust and retail brokerage, in an agency, fiduciary or retail brokerage capacity for its customers are excluded from the consolidated financial statements since they do not constitute assets of the Corporation. Assets held by the Wealth Management Department amounted to $389,000,000 and $342,000,000 at December 31, 2019 and 2018, respectively. Income from fiduciary, investment management and brokerage activities are included in other income. The Corporation has evaluated events and transactions occurring subsequent to the balance sheet date of December 31, 2019, for items that should potentially be recognized or disclosed in the consolidated financial statements. The evaluation was conducted through the date these consolidated financial statements were issued. Use of Estimates Financial statements prepared in accordance with GAAP require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies at the date of the consolidated financial statements, and revenues and expenses during the reporting period. Actual results could differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the determination of other than temporary impairment on securities, and the potential impairment of goodwill. Significant Group Concentrations of Credit Risk Most of the Corporation’s activities are with customers located within southcentral Pennsylvania and northern Maryland. Note C discusses the types of securities in which the Corporation invests. Note D discusses the types of lending in which the Corporation engages. Included in commercial real estate loans are loans made to lessors of non-residential dwellings that total $297,654,000, or 23.4%, of total loans at December 31, 2019. These borrowers are geographically disbursed throughout ACNB’s marketplace and are leasing commercial properties to a varied group of tenants including medical offices, retail space and recreational facilities. Because of the varied nature of the tenants in aggregate, management believes that these loans do not present any greater risk than commercial loans in general. Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash on hand, balances due from banks, and federal funds sold, all of which mature within 90 days. Securities Debt securities that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and recorded at amortized cost. Debt securities not classified as held to maturity or trading are classified as “available for sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported, net of tax, in other comprehensive income (loss). As of January 1, 2018, equity securities with readily determined fair values are recorded at fair value with changes in fair value recognized in net income. Prior to 2018, fair value changes were reported, net of tax, in other comprehensive income (loss). Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Declines in the fair value of held to maturity and available for sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses on debt securities, management considers (1) whether management intends to sell the security, or (2) if it is more likely than not that management will be required to sell the security before recovery, or (3) if management does not expect to recover the entire amortized cost basis. In assessing potential other-than-temporary impairment for equity securities, consideration is given to management’s intention and ability to hold the securities until recovery of unrealized losses. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by aggregate outstanding commitments from investors or current investor yield requirements. Net unrealized losses are recognized through a valuation allowance by charges to income. Mortgage loans held for sale are sold with the mortgage servicing rights released to another financial institution through a correspondent relationship. The correspondent financial institution absorbs all of the risk related to rate lock commitments. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loans sold. Loans The Corporation grants commercial, residential, and consumer loans to customers. A substantial portion of the loan portfolio is represented by mortgage loans throughout southcentral Pennsylvania and northern Maryland. The ability of the Corporation’s debtors to honor their contracts is dependent upon the real estate values and general economic conditions in this area. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. The loans receivable portfolio is segmented into commercial, residential mortgage, home equity lines of credit, and consumer loans. Commercial loans consist of the following classes: commercial and industrial, commercial real estate, and commercial real estate construction. The accrual of interest on residential mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Consumer loans (consisting of home equity lines of credit and consumer loan classes) are typically charged off no later than 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued, but not collected, for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Allowance for Credit Losses The allowance for credit losses consists of the allowance for loan losses and the reserve for unfunded lending commitments. The allowance for loan losses (the “allowance”) is established as losses are estimated to occur through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. 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 statement of condition. The amount of the reserve for unfunded lending commitments is not material to the consolidated financial statements. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectibility of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are 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 either doubtful, substandard, or special mention. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or 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 risk factors. These qualitative risk factors include:
• | lending policies and procedures, including underwriting standards and collection, charge-off and recovery practices;
• | national, regional and local economic and business conditions, as well as the condition of various market segments, including the impact on the value of underlying collateral for collateral dependent loans;
• | the nature and volume of the portfolio and terms of loans;
• | the experience, ability and depth of lending management and staff;
• | the volume and severity of past due, classified and nonaccrual loans, as well as other loan modifications; and,
• | the existence and effect of any concentrations of credit and changes in the level of such concentrations.
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 a narrative accompanying the allowance for loan loss calculation. The unallocated component of the allowance is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. It covers risks that are inherently difficult to quantify including, but not limited to, collateral risk, information risk, and historical charge-off risk. A loan is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal and/or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and/or interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial and commercial construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. A specific allocation within the allowance for loan losses is established for an impaired loan if its carrying value exceeds its estimated fair value. The estimated fair values of the Corporation’s impaired loans are measured based on the estimated fair value of the loan’s collateral or the discounted cash flows method. It is the policy of the Corporation to order an updated valuation on all real estate secured loans when the loan becomes 90 days past due and there has not been an updated valuation completed within the previous 12 months. In addition, the Corporation orders third-party valuations on all impaired real estate collateralized loans within 30 days of the loan being classified as impaired. Until the valuations are completed, the Corporation utilizes the most recent independent third-party real estate valuation to estimate the need for a specific allocation to be assigned to the loan. These existing valuations are discounted downward to account for such things as the age of the existing collateral valuation, change in the condition of the real estate, change in local market and economic conditions, and other specific factors involving the collateral. Once the updated valuation is completed, the collateral value is updated accordingly. For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging reports, equipment appraisals, or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. The Corporation actively monitors the values of collateral as well as the age of the valuation of impaired loans. The Corporation orders valuations at least every 18 months, or more frequently if management believes that there is an indication that the fair value has declined. For impaired loans secured by collateral other than real estate, the Corporation considers the net book value of the collateral, as recorded in the most recent financial statements of the borrower, and determines fair value based on estimates made by management. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Corporation does not separately identify individual consumer and residential loans for impairment disclosures, unless such loans are the subject of a troubled debt restructure. Loans whose terms are modified are classified as troubled debt restructured loans if the Corporation grants such borrowers concessions that it would not otherwise consider 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, a below market interest rate given the risk associated with the loan, or an extension of a loan’s stated maturity date. Nonaccrual troubled debt restructurings may be restored to accrual status if principal and interest payments, under the modified terms, are current for a sustained period of time and, based on a well-documented credit evaluation of the borrower’s financial condition, there is reasonable assurance of repayment. Loans classified as troubled debt restructurings are generally designated as impaired. The allowance calculation methodology includes further segregation of loan classes into credit quality rating categories. The borrower’s overall financial condition, repayment sources, guarantors, and value of collateral, if appropriate, are generally 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 classified 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. Loans not classified are rated pass. In addition, federal and state regulatory agencies, as an integral part of their examination process, periodically review the Corporation’s allowance for loan losses and may require the Corporation 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 and economic conditions, management believes the current level of the allowance for loan losses is adequate. Commercial and Industrial Lending — The Corporation originates commercial and industrial loans primarily to businesses located in its primary market area and surrounding areas. These loans are used for various business purposes which include short-term loans and lines of credit to finance machinery and equipment purchases, inventory, and accounts receivable. Generally, the maximum term for loans extended on machinery and equipment is based on the projected useful life of such machinery and equipment. Most business lines of credit are written on demand and may be renewed annually. Commercial and industrial loans are generally secured with short-term assets; however, in many cases, additional collateral such as real estate is provided as additional security for the loan. Loan-to-value maximum values have been established by the Corporation and are specific to the type of collateral. Collateral values may be determined using invoices, inventory reports, accounts receivable aging reports, collateral appraisals, etc. In underwriting commercial and industrial loans, an analysis is performed to evaluate the borrower’s character and capacity to repay the loan, the adequacy of the borrower’s capital and collateral, as well as the conditions affecting the borrower. Evaluation of the borrower’s past, present and future cash flows is also an important aspect of the Corporation’s analysis. Commercial loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions. Commercial Real Estate Lending — The Corporation engages in commercial real estate lending in its primary market area and surrounding areas. The Corporation’s commercial loan portfolio is secured primarily by commercial retail space, office buildings, and hotels. Generally, commercial real estate loans have terms that do not exceed 20 years, have loan-to-value ratios of up to 80% of the appraised value of the property, and are typically secured by personal guarantees of the borrowers. In underwriting these loans, the Corporation performs a thorough analysis of the financial condition of the borrower, the borrower’s credit history, and the reliability and predictability of the cash flow generated by the property securing the loan. Appraisals on properties securing commercial real estate loans originated by the Corporation are performed by independent appraisers. Commercial real estate loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions and the complexities involved in valuing the underlying collateral. Commercial Real Estate Construction Lending — The Corporation engages in commercial real estate construction lending in its primary market area and surrounding areas. The Corporation’s commercial real estate construction lending consists of commercial and residential site development loans, as well as commercial building construction and residential housing construction loans. The Corporation’s commercial real estate construction loans are generally secured with the subject property. Terms of construction loans depend on the specifics of the project, such as estimated absorption rates, estimated time to complete, etc. In underwriting commercial real estate construction loans, the Corporation performs a thorough analysis of the financial condition of the borrower, the borrower’s credit history, and the reliability and predictability of the cash flow generated by the project using feasibility studies, market data, etc. Appraisals on properties securing commercial real estate construction loans originated by the Corporation are performed by independent appraisers. Commercial real estate construction loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions and the uncertainties surrounding total construction costs. Residential Mortgage Lending — One-to-four family residential mortgage loan originations, including home equity closed-end loans, are generated by the Corporation’s marketing efforts, its present customers, walk-in customers, and referrals. These loans originate primarily within the Corporation’s market area or with customers primarily from the market area. The Corporation offers fixed-rate and adjustable-rate mortgage loans with terms up to a maximum of 30 years for both permanent structures and those under construction. The Corporation’s one-to-four family residential mortgage originations are secured primarily by properties located in its primary market area and surrounding areas. The majority of the Corporation’s residential mortgage loans originate with a loan-to-value of 80% or less. Loans in excess of 80% are required to have private mortgage insurance. In underwriting one-to-four family residential real estate loans, the Corporation evaluates both the borrower’s financial ability to repay the loan as agreed and the value of the property securing the loan. Properties securing real estate loans made by the Corporation are appraised by independent appraisers. The Corporation generally requires borrowers to obtain an attorney’s title opinion or title insurance, as well as fire and property insurance (including flood insurance, if necessary) in an amount not less than the amount of the loan. The Corporation has not engaged in subprime residential mortgage originations. Residential mortgage loans are subject to risk due primarily to general economic conditions, as well as a continued weak housing market. Home Equity Lines of Credit Lending — The Corporation originates home equity lines of credit primarily within the Corporation’s market area or with customers primarily from the market area. Home equity lines of credit are generated by the Corporation’s marketing efforts, its present customers, walk-in customers, and referrals. Home equity lines of credit are secured by the borrower’s primary residence with a maximum loan-to-value of 90% and a maximum term of 20 years. In underwriting home equity lines of credit, the Corporation evaluates both the value of the property securing the loan and the borrower’s financial ability to repay the loan as agreed. The ability to repay is determined by the borrower’s employment history, current financial condition, and credit background. Home equity lines of credit generally present a moderate level of risk due primarily to general economic conditions, as well as a continued weak housing market. 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 continues to be weak and property values deteriorate. Consumer Lending — The Corporation offers a variety of secured and unsecured consumer loans, including those for vehicles and mobile homes and loans secured by savings deposits. These loans originate primarily within the Corporation’s market area or with customers primarily from the market area. Consumer loan terms vary according to the type and value of collateral and the creditworthiness of the borrower. In underwriting consumer loans, a thorough analysis of the borrower’s financial ability to repay the loan as agreed is performed. The ability to repay is determined by the borrower’s employment history, current financial condition, and credit background. Consumer loans may entail greater credit risk than residential mortgage loans or home equity lines of credit, 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 as a result of the greater likelihood of damage, loss or depreciation. 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 which can be recovered on such loans. Acquired Loans Acquired Loans (impaired and non-impaired) are initially recorded at their acquisition-date fair values using Level 3 inputs. Fair values are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, expected lifetime losses, environmental factors, collateral values, discount rates, expected payments and expected prepayments. Specifically, the Corporation has prepared three separate loan fair value adjustments that it believed a market participant might employ in estimating the entire fair value adjustment necessary under ASC 820-10 for the acquired loan portfolio. The three-separate fair valuation methodology employed are: 1) an interest rate loan fair value adjustment, 2) a general credit fair value adjustment, and 3) a specific credit fair value adjustment for purchased credit impaired loans subject to ASC 310-30 procedures. The carryover of allowance for loan losses related to acquired loans is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. The allowance for loan losses on acquired loans reflects only those losses incurred after acquisition and represents the present value of cash flows expected at acquisition that is no longer expected to be collected. Acquired loans are marked to fair value on the date of acquisition. In conjunction with the quarterly evaluation of the adequacy of the allowance for loan losses, the Corporation performs an analysis on acquired loans to determine whether or not there has been subsequent deterioration in relation to those loans. If deterioration has occurred, the Corporation will include these loans in the calculation of the allowance for loan losses after the initial valuation, and provide accordingly. Upon acquisition, in accordance with US GAAP, the Corporation has individually determined whether each acquired loan is within the scope of ASC 310-30. The Corporation’s senior lending management reviewed the accounting seller’s loan portfolio on a loan by loan basis to determine if any loans met the two-part definition of an impaired loan as defined by ASC 310-30: 1) Credit deterioration on the loan from its inception until the acquisition date, and 2) It is probable that not all of the contractual cash flows will be collected on the loan. Acquired ASC 310-20 loans, which are loans that did not meet the criteria above, were pooled into groups of similar loans based on various factors including borrower type, loan purpose, and collateral type. For these pools, the Corporation used certain loan information, including outstanding principal balance, estimated expected losses, weighted average maturity, weighted average margin, and weighted average interest rate along with estimated prepayment rates, expected lifetime losses, environment factors to estimate the expected cash flow for each loan pool. With regards to ASC 310-30 loans, for external disclosure purposes, the aggregate contractual cash flows less the aggregate expected cash flows resulted in a credit related non-accretable yield amount. The aggregate expected cash flows less the acquisition date fair value resulted in an accretable yield amount. The accretable yield reflects the contractual cash flows management expects to collect above the loan’s acquisition date fair value and will be recognized over the life of the loan on a level-yield basis as a component of interest income. Over the life of the acquired ASC 310-30 loan, the Corporation continues to estimate cash flows expected to be collected. Decreases in expected cash flows, other than from prepayments or rate adjustments, are recognized as impairments through a charge to the provision for credit losses resulting in an increase in the allowance for credit losses. Subsequent improvements in cash flows result in first, reversal of existing valuation allowances recognized subsequent to acquisition, if any, and next, an increase in the amount of accretable yield to be subsequently recognized on a prospective basis over the loan’s remaining life. Acquired ASC 310-30 loans that met the criteria for non-accrual of interest prior to acquisition are considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if we can reasonably estimate the timing and amount of expected cash flows on such loans. Accordingly, we do not consider acquired contractually delinquent loans to be non-accruing and continue to recognize interest income on these loans using the accretion model. For loans acquired without evidence of credit quality deterioration, ACNB prepared the interest rate loan fair value and credit fair value adjustments. Loans were grouped into homogeneous pools by characteristics such as loan type, term, collateral, and rate. Market rates for similar loans were obtained from various internal and external data sources and reviewed by management for reasonableness. The average of these rates was used as the fair value interest rate a market participant would utilize. A present value approach was utilized to calculate the interest rate fair value discount of $731,000. Additionally, for loans acquired without credit quality deterioration, a credit fair value adjustment was calculated using a two-part credit fair value analysis: 1) expected lifetime credit migration losses; and 2) estimated fair value adjustment for certain qualitative factors. The expected lifetime losses were calculated using historical losses observed at the Bank, NWSB and peer banks. ACNB also estimated an environmental factor to apply to each loan type. The environmental factor represents potential discount which may arise due to general credit and economic factors. A credit fair value discount of $4.5 million was determined. Both the interest rate and credit fair value adjustments relate to loans acquired with evidence of credit quality deterioration will be substantially recognized as interest income on a level yield amortization method over the expected life of the loans. Premises and Equipment Land is carried at cost. Buildings, furniture, fixtures, equipment and leasehold improvements are carried at cost, less accumulated depreciation. Depreciation is computed principally by the straight-line method over the assets’ estimated useful lives. Normally, a buildings useful life is 40 years, except for building remodels and additions, which are depreciated over fifteen years. Bank equipment, including furniture and fixtures, is normally depreciated over five - fifteen years depending upon the nature of the purchase. 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. Amortization of leasehold improvements is computed by straight line over the shorter of the assets’ useful life or the related lease term. Restricted Investment in Bank Stocks Restricted investment in bank stocks, which represents required investments in the common stock of correspondent banks, is carried at cost as of December 31, 2019 and 2018, and consists of common stock in the Atlantic Central Bankers Bank, Maryland Financial Bank, Community Bankers Bank and Federal Home Loan Bank (FHLB). Management evaluates the restricted investment in bank stocks for impairment in accordance with Accounting Standard Codification (ASC) Topic 942, Financial Services—Depository and Lending. Management’s determination of whether these investments are impaired is based on their assessment of the ultimate recoverability of their cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of their cost is influenced by criteria such as (1) the significance of the decline in net assets of the correspondent bank as compared to the capital stock amount for the correspondent bank and the length of time this situation has persisted, (2) commitments by the correspondent bank to make payments required by law or regulation and the level of such payments in relation to the operating performance of the correspondent bank, (3) the impact of legislative and regulatory changes on institutions and, accordingly, on the customer base of the correspondent bank, and (4) the liquidity position of the correspondent bank. Management believes no impairment charge was necessary related to the restricted investment in bank stocks during 2019 or 2018. However, security impairment analysis is completed quarterly, and the determination that no impairment has occurred during those years is no assurance that impairment may not occur in future periods. Bank-Owned Life Insurance The Corporation’s banking subsidiary maintains nonqualified compensation plans for selected senior officers. To fund the benefits under these plans, the Bank is the owner of single premium life insurance policies on participants in the nonqualified retirement plans. Investment in bank-owned life insurance policies was used to finance the nonqualified compensation plans and provide tax-exempt income to the Corporation. ASC Topic 715, Compensation—Retirement Benefits, requires a liability to be recorded during the service period when a split-dollar life insurance agreement continues after participants’ employment or retirement. The required accrued liability is based on either the post-employment benefit cost for continuing life insurance or based on the future death benefit depending on the contractual terms of the underlying agreement. The Corporation’s liability is based on the post-employment benefit cost for continuing life insurance. The Corporation incurred approximately $161,000 and $95,000 of expense in 2019 and 2018, respectively, related to these benefits. Investments in Low-Income Housing Partnerships The Corporation’s investments in low-income housing partnerships are accounted for using the “equity method” prescribed by ASC Topic 323, Investments — Equity Method. In accordance with ASC Topic 740, Income Taxes, tax credits are recognized as they become available. Any residual loss is amortized as the tax credits are received. Goodwill and Intangible Assets The Corporation accounts for its acquisitions using the acquisition accounting method required by ASC Topic 805, Business Combinations. Acquisition accounting requires the total purchase price to be allocated to the estimated fair values of assets and liabilities acquired, including certain intangible assets that must be recognized. Generally, this results in a residual amount in excess of the net fair values, which is recorded as goodwill. ASC Topic 350, Intangibles—Goodwill and Other, requires that goodwill is not amortized to expense, but rather that it be assessed or tested for impairment at least annually. If certain events occur which might indicate goodwill has been impaired, the goodwill is tested for impairment when such events occur. Impairment write-downs are charged to results of operations in the period in which the impairment is determined. The Corporation did not identify any impairment on RIG’s outstanding goodwill from its most recent testing, which was performed as of October 1, 2019. The Corporation did not identify any impairment on the Bank’s outstanding goodwill from its most recent qualitative assessment, which was completed as of December 31, 2019. If certain events occur which might indicate goodwill has been impaired, the goodwill is tested for impairment when such events occur. Other acquired intangible assets that have finite lives, such as core deposit intangibles, customer relationship intangibles and renewal lists, are amortized over their estimated useful lives and subject to periodic impairment testing. Core deposit intangibles are primarily amortized over ten years using accelerated methods. Customer renewal lists are amortized using the straight line method over their estimated useful lives which range from eight to fifteen years. Foreclosed Assets Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value, less costs to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are adjusted to the fair value, less costs to sell as necessary. Revenue and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed assets. $83,000 of the $364,000 outstanding foreclosed asset balance held at December 31, 2019 represent residential real estate properties. Income Taxes The Corporation 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. The Corporation 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 bases 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. The Corporation 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%; 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% 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. The Corporation recognizes interest and penalties on income taxes, if any, as a component of income tax expense. Retirement Plan The compensation cost of an employee’s pension benefit is recognized on the projected unit credit method over the employee’s approximate service period. The aggregate cost method is utilized for funding purposes. Stock-based Compensation The ACNB Corporation 2009 Restricted Stock plan expired by its own terms after 10 years on February 24, 2019. The purpose of this plan was to provide employees and directors of the Bank who have responsibility for its growth with additional incentives by allowing them to acquire ownership in the Corporation and, thereby, encouraging them to contribute to the success of the Corporation. As of December 31, 2019, 25,945 shares issued under the plan, of which 23,730 shares are fully vested and the remaining 2,215 will vest over the next year. No further shares may be issued under this restricted stock plan. The Corporation’s Registration Statement under the Securities Act of 1933 on Form S-8 for the ACNB Corporation 2009 Restricted Stock Plan was filed with the Securities and Exchange Commission on January 4, 2013. Post-Effective Amendment No. 1 to this Form S-8 was filed with the Commission on March 8, 2019, effectively transferring the 174,055 authorized, but not issued, shares under the ACNB Corporation 2009 Restricted Stock Plan to the ACNB Corporation 2018 Omnibus Stock Incentive Plan. On May 1, 2018, shareholders approved and ratified the ACNB Corporation 2018 Omnibus Stock Incentive Plan, effective as of March 20, 2018, in which awards shall not exceed, in the aggregate, 400,000 shares of common stock, plus any shares that are authorized, but not issued, under the ACNB Corporation 2009 Restricted Stock Plan. As of December 31, 2019, 16,115 shares were issued under this plan, of which 5,372 are fully vested and the remaining 10,743 will vest over the next two years. The Corporation’s Registration Statement under the Securities Act of 1933 of Form S-8 for the ACNB Corporation 2018 Omnibus Stock Incentive Plan was filed with the Securities and Exchange Commission on March 8, 2019. In addition, on March 8, 2019, the Corporation filed Post-Effective Amendment No. 1 to the Registration Statement on Form S-8 for the ACNB Corporation 2009 Restricted Stock Plan to add the ACNB Corporation 2018 Omnibus Stock Incentive Plan to the registration statement. Plan expense is recognized over the vesting period of the stock issued under both plans. $322,000 and $186,000 of compensation expenses related to the grants were recognized for the years ended December 31, 2019 and 2018, respectively. Net Income per Share The Corporation has a simple capital structure. Basic earnings per share of common stock is computed based on 7,061,524 and 7,035,818 weighted average shares of common stock outstanding for 2019 and 2018, respectively. All outstanding unvested restricted stock awards that contain rights to nonforfeitable dividends are considered participating for this calculation. Advertising Costs Costs of advertising, which are included in marketing expenses, are expensed when incurred. Off-Balance Sheet Credit-Related Financial Instruments In the ordinary course of business, the Corporation has entered into commitments to extend credit, including commitments under commercial lines of credit, and standby letters of credit. Such financial instruments are recorded when they are funded. Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Corporation, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets. Accumulated Other Comprehensive Loss The components of the accumulated other comprehensive loss, net of taxes, are as follows:
In thousands | Unrealized Losses on Securities |  | Pension Liability |  | Accumulated Other Comprehensive Loss
BALANCE — DECEMBER 31, 2019 | $ | 1,261 |  |  | $ | (7,114 | ) |  | $ | (5,853 | )
BALANCE — DECEMBER 31, 2018 | $ | (1,651 | ) |  | $ | (7,566 | ) |  | $ | (9,217 | )
Segment Reporting The Bank acts as an independent community financial services provider, which offers traditional banking and related financial services to individual, business, and government customers. Through its branch and automated teller machine networks, the Bank offers a full array of commercial and community financial services, including the taking of time, savings, and demand deposits; the making of commercial, consumer, and mortgage loans; and the providing of other financial services. Management does not separately allocate expenses, including the cost of funding loan demand, between the commercial, community and mortgage banking operations of the Bank. As such, discrete financial information for commercial, community and mortgage banking operations is not available and segment reporting would not be meaningful. Please refer to Note S — “Segment and Related Information” for a discussion of insurance operations. New Accounting Pronouncements The Corporation early adopted ASU 2017-04, Simplifying the Test for Goodwill Impairment. The ASU eliminates Step 2 of the goodwill impairment test. As such, an entity will perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the reporting unit’s carrying amount exceeds its fair value. If fair value exceeds the carrying amount, no impairment should be recorded. Any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Impairment losses on goodwill cannot be reversed once recognized. An entity may still perform the optional qualitative assessment for a reporting unit to determine if it is more likely than not that goodwill is impaired. However, the ASU eliminates the requirement to perform a qualitative assessment for any reporting unit with a zero or negative carrying amount. Therefore, the same one-step impairment assessment will apply to all reporting units. However, for a reporting unit with a zero or negative carrying amount, the ASU adds a requirement to disclose the amount of goodwill allocated to it and the reportable segment in which it is included. The amendments in this ASU were early adopted in the 2018 fiscal year and did not have a material effect on the Corporation’s consolidated financial condition or results of operations. On January 1, 2019, the Corporation adopted ASU 2016-02, Leases, and all subsequent amendments to the ASU (collectively “Topic 842”). From the lessee’s perspective, the new standard establishes a right-of-use (ROU) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement for a lessee. Under the optional transition method, only the most recent period presented reflects the adoption of Topic 842 and the comparative prior periods are reported under the previous guidance in Topic 840. The Corporation recorded a $4 million right-of-use asset and lease liability, which represents all of its operating lease commitments, based on the present value of committed lease payments. The ASU offers lessors a practical expedient that mirrors the practical expedient already provided to lessees in ASU 2016-02, Leases (Topic 842). The Corporation adopted the new practical expedient which will allow the Corporation to elect, by class of underlying asset, to not separate nonlease components from the associated lease component when specified conditions are met. Examples of nonlease components include equipment maintenance services, common area maintenance services in real estate, or other goods or services provided to the lessee apart from the right to use the underlying asset. The practical expedient must be applied consistently for all lease contracts. The effect on operations and capital adequacy was not material. On January 1, 2019, the Corporation adopted ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for premiums on purchased callable debt securities to the earliest call date (i.e., yield-to-earliest call amortization), rather than amortizing over the full contractual term. The ASU does not change the accounting for securities held at a discount. The amendments apply to callable debt securities with explicit, noncontingent call features that are callable at fixed prices and on preset dates. If a security may be prepaid based upon prepayments of the underlying loans, not because the issuer exercised a date specific call option, it is excluded from the scope of the new standard. However, for instruments with contingent call features, once the contingency is resolved and the security is callable at a fixed price and preset date, the security is within the scope of the amendments. Further, the amendments apply to all premiums on callable debt securities, regardless of how they were generated. The amendments require companies to reset the effective yield using the payment terms of the debt security if the call option is not exercised on the earliest call date. If the security has additional future call dates, any excess of the amortized cost basis over the amount repayable by the issuer at the next call date should be amortized to the next call date. The adoption of this ASU did not have a material effect on the Corporation’s consolidated financial condition or results of operations. The Corporation adopted ASU 2018-09, Codification Improvements. The ASU contains various improvements to various topics in the codification, including clarification that an entity must disclose the required and actual amounts of regulatory capital for each measure of regulatory capital for which the entity must comply. The adoption of this ASU did not impact the Corporation’s consolidated financial condition or results of operations since the Corporation already discloses capital requirements within the Management’s Discussion and Analysis section of this Form 10-K. The Corporation early adopted ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. This ASU removes, modifies and adds to existing fair value measurement disclosure requirements. The ASU would be effective for all entities in fiscal years beginning after December 15, 2019, including interim periods, which is first effective for calendar year entities in the March 31, 2020, interim financial statements. In addition, an entity may early adopt any of the removed or modified disclosures immediately and delay adoption of the new disclosures until the effective date. The adoption of this ASU did not have a material effect on the Corporation’s consolidated financial condition or results of operations. ASU 2016-13 In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 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 credit losses 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 for credit losses 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 (AFS) 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. Until recently, the new CECL standard was expected to become effective for the Corporation on January 1, 2020, and for interim periods within that year. In October 2019, FASB voted to delay implementation of the new CECL standard for certain companies, including those companies that qualify as a smaller reporting company under SEC rules, until January 1, 2023. The Corporation currently expects to continue to qualify as a smaller reporting company, based upon the current SEC definition, and as a result, will likely be able to defer implementation of the new CECL standard for a period of time. The Corporation will not early adopt as of January 1, 2020, but will continue to review factors that might indicate that the full deferral time period should not be used. The Corporation continues to evaluate the impact the CECL model will have on the accounting for credit losses, but the Corporation expects to recognize a one-time cumulative-effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, consistent with regulatory expectations set forth in interagency guidance issued at the end of 2016. The Corporation cannot yet determine the magnitude of any such one-time cumulative adjustment or of the overall impact of the new standard on its consolidated financial condition or results of operations. Management has developed a committee to address CECL and the committee is currently evaluating options to comply with the ASU in a timely manner. ASU 2018-14 In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Topic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans. The ASU removes the following disclosures:
• | the amounts in accumulated other comprehensive income that the entity expects to recognize in net periodic benefit cost during the next fiscal year;
• | the amount and timing of plan assets expected to be returned to the employer; and,
• | certain related party disclosures.
The ASU clarifies the following disclosure requirements:
• | the projected benefit obligation (PBO) and fair value of plan assets for plans with PBOs in excess of plan assets must be disclosed; and,
• | the accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets must be disclosed.
The ASU adds the following disclosure requirements:
• | the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates; and,
• | an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period.
The ASU is effective for public business entities in fiscal years ending after December 15, 2020. Early adoption is permitted. The Corporation is currently evaluating the impact this ASU will have on its consolidated financial condition or results of operations.
