CNB Financial Corporation (the "Corporation") is headquartered in Clearfield, Pennsylvania, and provides a full range of banking and related services through its wholly owned subsidiary, CNB Bank (the "Bank"). In addition, the Bank provides wealth and asset management services, including the administration of trusts and estates, retirement plans, and other employee benefit plans as well as a full range of wealth management services. The Bank serves individual and corporate customers and is subject to competition from other financial institutions and intermediaries with respect to these services. In addition to the Bank, the Corporation also operates a consumer discount loan and finance business through its wholly owned subsidiary, Holiday Financial Services Corporation ("Holiday"). The Corporation and its other subsidiaries are subject to examination by federal and state regulators. The Corporation’s market area is primarily concentrated in the central and northwest regions of the Commonwealth of Pennsylvania, the central and northeast regions of the state of Ohio, western New York and Roanoke, Virginia.

The financial statements are consolidated to include the accounts of the Corporation, the Bank, CNB Securities Corporation, Holiday, CNB Risk Management, Inc. and CNB Insurance Agency. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements. Certain prior period amounts have been reclassified to conform to the current period presentation. Reclassifications had no effect on prior year net income or shareholders’ equity.

The worldwide spread of COVID-19 has created significant uncertainty in the global economy. There have been no comparable recent events that provide guidance as to the effects the global COVID-19 pandemic may have, and, as a result, the ultimate impact of the COVID-19 pandemic and the extent to which the COVID-19 pandemic and the related government responses impact the Corporation’s business, results of operations and financial condition will depend on future developments, which are highly uncertain and difficult to predict.

The Corporation's business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain the COVID-19 pandemic requires further restricted measures or is unsuccessful, the Corporation could experience a material adverse effect on its business, financial condition, results of operations and cash flows. Since the extent to which the COVID-19 pandemic impacts its operations will depend on future developments that are highly uncertain, the Corporation cannot estimate the impact on its business, financial condition or near or long-term financial or operational results with reasonable certainty. Accordingly, the Corporation is disclosing potentially material items of which it is aware.

The COVID-19 pandemic could cause a decline in the Corporation's stock price or the occurrence of what management would deem to be a triggering event that could, under certain circumstances, cause us to perform a goodwill impairment test, resulting in an impairment charge being recorded for that period. In the event that the Corporation concludes that all or a portion of its goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded to earnings.

Credit: The Corporation is working with customers directly affected by the COVID-19 pandemic. The Corporation has offered assistance in accordance with regulator guidelines. As a result of the current economic slowdown related to the COVID-19 pandemic, the Corporation is engaging in more frequent communication with borrowers to better understand their situation and the challenges faced, allowing it to respond proactively as needs and issues arise.

Determining the appropriateness of the allowance for credit losses on loans is complex and requires judgment by management about the effect of matters that are inherently uncertain. Subsequent evaluations of the then-existing loan portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for credit losses on loans in those future periods. Should economic conditions worsen, the Corporation could experience further increases in its required allowance for credit losses and record additional provision expense. It is possible that the Corporation's asset quality measures could worsen at future measurement periods if the effects of the COVID-19 pandemic are prolonged.

While the Corporation monitors the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Corporation-wide basis, and operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.

For purposes of the consolidated statement of cash flows, the Corporation defines cash and cash equivalents as cash and due from banks, interest bearing deposits with other banks, and Federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing time deposits with other banks and borrowings with original maturities of 90 days or less.

Debt securities are classified as held to maturity and carried at amortized cost when management has the positive intent and ability to hold them to maturity. Debt securities are classified as available for sale when they might be sold before maturity. Securities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax.

Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method.

The Corporation has made a policy election to exclude accrued interest from the amortized cost basis of debt securities and report accrued interest separately in accrued interest receivable and other assets in the consolidated balance sheets. A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a security placed on nonaccrual is reversed against interest income. There was no accrued interest related to debt securities reversed against interest income for the year ended December 31, 2021.

For available-for-sale debt securities in an unrealized loss position, the Corporation first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. For debt securities available-for-sale that do not meet the aforementioned criteria, the Corporation evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income.

Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management confirms that an available-for-sale security is uncollectable or when either of the criteria regarding intent or requirement to sell is met. As of December 31, 2021 and December 31, 2020, the Corporation determined that the unrealized loss positions in available-for-sale debt securities were not the result of credit losses, and therefore, an allowance for credit losses was not recorded. See Note 3, "Debt Securities," and Note 6, "Fair Value Measurements," for more information about available-for-sale debt securities.

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, deferred loan fees and costs. Accrued interest receivable totaled $13.3 million and $15.4 million at December 31, 2021 and December 31, 2020, respectively, and was reported in accrued interest receivable and other assets on the consolidated balance sheets and is excluded from the estimate of credit losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments.

Interest income on mortgage and commercial loans is discontinued and placed on nonaccrual status at the time the loan is 90 days delinquent unless the loan is well secured and in process of collection. Consumer loans continue to accrue interest until they are recorded as charge-offs no later than 180 days past due unless the loan is in the process of collection. Past-due status is based on the contractual terms of the loan. Loans, including loans modified in a troubled debt restructuring, are placed on nonaccrual or recorded as charge-offs at an earlier date if collection of principal or interest is considered doubtful.

All interest accrued but not received on loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Under the cash-basis method, interest income is recorded when the payment is received in cash. For all portfolio segments, loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

PCD loans are recorded at the amount paid. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan's purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense.

Loans are classified as TDRs when a borrower is experiencing financial difficulty and the Corporation has granted a concession that would not have otherwise been made for a borrower with similar credit characteristics. Prior to granting a modification, the borrower's ability to repay the loan is evaluated, including: current income levels and debt to income ratio, credit score, payment history and an evaluation of secondary repayment sources, if any is updated. The Corporation's policy is to modify loans typically through a payment reduction or through an interest rate reduction for a specified period of time, usually six to twelve months. Interest-only payments may also be approved during the modification period. Principal forgiveness is generally not an option for modification. The allowance for credit loss on a TDR is measured using the same method as all other loans held for investment, except the original interest rate is used to discount the expected cash flows, not the rate specified within the restructuring. When there is a reasonable expectation, at the reporting date, that a TDR will be executed with a borrower the estimated life of the TDR reflects the extension or renewal. The Corporation also modifies some loans that are not classified as TDRs as the modification is due to a restructuring where the effective interest rate on the debt is reduced to reflect a decrease in market interest rates.

The Corporation has implemented various consumer and commercial loan modification programs to provide its borrowers relief from the economic impacts of COVID-19. In accordance with the CARES Act, loans to borrowers experiencing financial difficulty related to the COVID-19 pandemic which were granted short-term modifications after March 1, 2020 and which were not more than 30 days past due as of December 31, 2019 are exempt from TDR classification. In addition, for loans modified in response to the COVID-19 pandemic that do not meet the above delinquency criteria (e.g., more than 30 days past due as of December 31, 2019), the Corporation applies the guidance included in an interagency statement issued by the bank regulatory agencies. This guidance states that loan modifications performed in light of the COVID-19 pandemic, including loan payment deferrals that are up to six months in duration, that were granted to borrowers who were less than 30 days past due as of the implementation date of a loan modification program are exempt from TDR classification. For loan modifications that include a payment deferral and are not TDRs, the borrower’s past due and nonaccrual status will not be impacted during the deferral period. Interest income will continue to be recognized over the contractual life of the loan.

The expense for credit loss recorded through earnings is the amount necessary to maintain the allowance for credit losses on loans at the amount of expected credit losses inherent within the loan portfolio. Loans are recorded as charge-offs against the allowance when management confirms a loan balance is uncollectable. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts, and other significant qualitative and quantitative factors. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, changes in environmental conditions, delinquency level, segment growth rates and changes in duration within new markets, or other relevant factors. For further information on the allowance for credit losses on loans, see Note 4, "Loans," for additional detail.

1-4 Family Construction: The Bank originates construction loans to finance 1-4 family residential buildings. Construction loans include not only construction of new structures, but also additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Construction loans are generally secured by real estate. The primary risk characteristics are specific to the uncertainty on whether the construction will be completed according to the specifications and schedules. Factors that may influence the completion of construction may be customer specific, or related to changes in general economic conditions.

Other construction loans and all land development and other land loans: The Bank originates construction loans to finance land development preparatory to erecting new structures or the on-site construction of industrial, commercial, or multi-family buildings. Construction loans include not only construction of new structures, but also additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Construction loans are generally secured by real estate. The primary risk characteristics are specific to the uncertainty on whether the construction will be completed according to the specifications and schedules. Factors that may influence the completion of construction may be customer specific, such as the quality and depth of property management, or related to changes in general economic conditions.

Farmland (including farm residential and other improvements): The Bank originates loans secured by farmland and improvements thereon, secured by mortgages. Farmland includes all land known to be used or usable for agricultural purposes, such as crop and livestock production. Farmland also includes grazing or pasture land, whether tillable or not and whether wooded or not. The primary risk characteristics are specific to the uncertainty on production, market, financial, environmental and human resources.

Home equity lines of credit: The primary risk characteristics associated with home equity lines of credit typically involve changes to the borrower, including unemployment or other loss of income; unexpected significant expenses, such as major medical expenses, catastrophic events, divorce and death. Home equity lines of credit are typically originated with variable or floating interest rates, which could expose the borrower to higher payments in a rising interest rate environment. Real estate values could decrease and cause the value of the underlying property to fall below the loan amount, creating additional potential loss exposure for the Bank.

Residential Mortgages secured by first liens: The Bank originates one-to-four family residential mortgage loans primarily within central and northwest Pennsylvania, central and northeast Ohio, western New York and the Roanoke, Virginia market. These loans are secured by first liens on a primary residence or investment property. The primary risk characteristics associated with residential mortgage loans typically involve major changes to the borrower, including unemployment or other loss of income; unexpected significant expenses, such as major medical expenses, catastrophic events, divorce or death. Residential mortgage loans that have adjustable rates could expose the borrower to higher payments in a rising interest rate environment. Real estate values could decrease and cause the value of the underlying property to fall below the loan amount, creating additional potential loss exposure for the Bank.

Residential Mortgages secured by junior liens: The Bank originates loans secured by junior liens against one to four family properties primarily within central and northwest Pennsylvania, central and northeast Ohio, western New York and the Roanoke, Virginia market. Loans secured by junior liens are primarily in the form of an amortizing home equity loan. These loans are subordinate to a first mortgage which may be from another lending institution. The primary risk characteristics associated with loans secured by junior liens typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Real estate values could decrease and cause the value of the property to fall below the loan amount, creating additional potential loss exposure for the Bank.

Multifamily (5 or more) residential properties: The Bank originates mortgage loans for multifamily properties primarily within central and northwest Pennsylvania, central and northeast Ohio, western New York and the Roanoke, Virginia market. Multifamily loans are expected to be repaid from the cash flows of the underlying property so the collective amount of rents must be sufficient to cover all operating expenses, property management and maintenance, taxes and debt service. Increases in vacancy rates, interest rates or other changes in general economic conditions can have an impact on the borrower and its ability to repay the loan.

Owner-occupied, nonfarm nonresidential properties: The Bank originates mortgage loans to operating companies primarily within central and northwest Pennsylvania, central and northeast Ohio, western New York and the Roanoke, Virginia market. Owner-occupied real estate properties primarily include retail buildings, medical buildings and industrial/warehouse space. Owner-occupied loans are typically repaid first by the cash flows generated by the borrower’s business operations. The primary risk characteristics are specific to the underlying business and its ability to generate sustainable profitability and positive cash flow. Factors that may influence a borrower's ability to repay their loan include demand for the business’ products or services, the quality and depth of management, the degree of competition, regulatory changes, and general economic conditions.

Non-owner occupied, nonfarm nonresidential properties: The Bank originates mortgage loans for commercial real estate that is managed as an investment property primarily within central and northwest Pennsylvania, central and northeast Ohio, western New York and the Roanoke, Virginia market. Commercial real estate properties primarily include retail buildings/shopping centers, hotels, office/medical buildings and industrial/warehouse space. Increases in vacancy rates, interest rates or other changes in general economic conditions can have an impact on the borrower and its ability to repay the loan. Commercial real estate loans are generally considered to have a higher degree of credit risk as they may be dependent on the ongoing success and operating viability of a fewer number of tenants who are occupying the property and who may have a greater degree of exposure to economic conditions.

Agricultural production and other loans to farmers: The Bank originates loans secured or unsecured to farm owners and operators (including tenants) or to nonfarmers for the purpose of financing agricultural production, including the growing and storing of crops, the marketing or carrying of agricultural products by the growers thereof, and the breeding, raising, fattening, or marketing of livestock, and for purchases of farm machinery, equipment, and implements. The primary risk characteristics are specific to the uncertainty on production, market, financial, environmental and human resources.

Commercial and Industrial: The Bank originates lines of credit and term loans to operating companies for business purposes. The loans are generally secured by business assets such as accounts receivable, inventory, business vehicles and equipment as well as the stock of a company, if privately held. Commercial and Industrial loans are typically repaid first by the cash flows generated by the borrower’s business operations. The primary risk characteristics are specific to the underlying business and its ability to generate sustainable profitability and positive cash flow. Factors that may influence a borrower's ability to repay their loan include demand for the business’ products or services, the quality and depth of management, the degree of competition, regulatory changes, and general economic conditions. The ability of the Bank to foreclose and realize sufficient value from business assets securing these loans is often uncertain. To mitigate the risk characteristics of commercial and industrial loans, commercial real estate may be included as a secondary source of collateral. The Bank will often require more frequent reporting requirements from the borrower in order to better monitor its business performance.

Credit cards: The Bank originates credit cards offered to individuals and businesses for household, family, other personal and business expenditures. Credit cards generally are floating rate loans and include both unsecured and secured lines. Credit card loans generally do not have stated maturities and are unconditionally cancellable. The primary risk characteristics associated with credit cards typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death.

Other revolving credit plans: The Bank originates lines of credit to individuals for household, family, and other personal expenditures. Consumer loans generally have higher interest rates and shorter terms than residential loans but tend to have higher credit risk due to the type of collateral securing the loan or in some cases the absence of collateral. The primary risk characteristics associated with other revolving loans typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death.

Automobile: The Bank originates consumer loans extended for the purpose of purchasing new and used passenger cars and other vehicles such as minivans, vans, sport-utility vehicles, pickup trucks, and similar light trucks for personal use. The primary risk characteristics associated with automobile loans typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death.

Other consumer: The Bank originates loans to individuals for household, family, and other personal expenditures. This also represents all other loans that cannot be categorized in any of the previous mentioned consumer loan segments. Consumer loans generally have higher interest rates and shorter terms than residential loans but tend to have higher credit risk due to the type of collateral securing the loan or in some cases the absence of collateral. The primary risk characteristics associated with other consumer loans typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death.

Obligations (other than securities and leases) of states and political subdivisions: The Bank originates various types of loans made directly to municipalities. These loans are repaid through general cash flows or through specific revenue streams, such as water and sewer fees. The primary risk characteristics associated with municipal loans are the municipality's ability to manage cash flow, balance the fiscal budget, fixed asset and infrastructure requirements. Additional risks include changes in demographics, as well as social and political conditions.

Methods utilized by management to estimate expected credit losses include a discounted cash flow ("DCF") model that discounts instrument-level contractual cash flows, adjusted for prepayments and curtailments, incorporating loss expectations, and a weighted average remaining maturity ("WARM") model which contemplates expected losses at a pool-level, utilizing historic loss information.

Under both models, management estimates the allowance for credit losses on loans using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. After the end of the reasonable and supportable forecast period, the loss rates revert to the mean loss rate over a period of eight quarters.

Historical credit loss experience, including examination of loss experience at representative peer institutions when the Corporation’s loss history does not result in estimations that are meaningful to users of the Corporation’s Consolidated Financial Statements, provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, changes in environmental conditions, delinquency level, segment growth rates and changes in duration within new markets, or other relevant factors.

The DCF model uses inputs of current and forecasted macroeconomic indicators to predict future loss rates. The current macroeconomic indicator utilized by the Corporation is the Federal unemployment rate and the S&P/Case-Shiller U.S. National Home Price Index for select collective residential related pools. In building the CECL methodology utilized in the DCF model, a correlation between this indicator and historic loss levels was developed, enabling a prediction of future loss rates related to future Federal unemployment rates and S&P/Case-Shiller U.S. National Home Price Index.

Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation and typically represent collateral dependent loans but may also include other nonperforming loans or TDRs. The Corporation uses the practical expedient to measure individually evaluated loans as collateral dependent and/or when repayment is expected to be provided substantially through the operation or sale of the collateral. Expected credit losses are based on the fair value at the reporting date, adjusted for selling costs as appropriate. For collateral dependent loans, credit loss is measured as the difference between the amortized cost basis in the loan and the fair value of the underlying collateral. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral.

Management estimates expected credit losses over the contractual period in which the Corporation is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Corporation. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. Management estimates the amount of expected losses by calculating a commitment usage factor over the contractual period for exposures that are not unconditionally cancellable by the Bank and applying the loss factors used in the allowance for credit losses on loans methodology to the results of the usage calculation to estimate the liability for credit losses related to unfunded commitments for each loan segment. The estimate of credit losses on OBS credit exposures is not material at December 31, 2021 or December 31, 2020.

When mortgage loans are sold with servicing retained, servicing rights are initially recorded at fair value with the income statement effect recorded in mortgage banking income. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. The Corporation compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans.

Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Corporation later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with mortgage banking income on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses.

Servicing fee income, which is reported on the income statement as mortgage banking income, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income. Late fees and ancillary fees related to loan servicing are not material.

Foreclosed assets are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed.

Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation of premises and equipment is computed principally by the straight line method. In general, useful lives range from 3 to 39 years with lives for furniture, fixtures and equipment ranging from 3 to 10 years and lives of buildings and building improvements ranging from 15 to 39 years. Amortization of leasehold improvements is computed using the straight-line method over useful lives of the leasehold improvements or the term of the lease, whichever is shorter. Maintenance, repairs and minor renewals are charged to expense as incurred.

Operating lease right-of-use assets represent the Corporation's right to use an underlying asset during the lease term and operating lease liabilities represent the Corporation's obligation to make lease payments arising from the lease. The period over which the right-of-use asset is amortized is generally the lesser of the expected remaining term or the remaining useful life of the leased asset. The lease liability is decreased as periodic lease payments are made. The Corporation performs impairment assessments for right-of-use assets when events or changes in circumstances indicate that their carrying values may not be recoverable.

The calculated amounts of the right-of-use assets and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of the minimum remaining lease payments. The Corporation's lease agreements often include one or more options to renew at the Corporation's discretion. If, at lease inception, the Corporation considers the exercising of a renewal option to be reasonably certain, the Corporation includes the extended term in the calculation of the right-of-use asset and lease liability. Generally, the Corporation cannot practically determine the interest rate implicit in the lease so the Corporation's incremental borrowing rate is used as the discount rate for the lease. The Corporation uses Federal Home Loan Bank ("FHLB") of Pittsburgh advance interest rates, which have been deemed as the Company's incremental borrowing rate, at lease inception based upon the term of the lease. The Corporation's lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Lease expense, variable lease expense and short-term lease expense are included in occupancy expense in the Corporation's consolidated statements of income. For facility-related leases, the Corporation elected, by lease class, to not separate lease and non-lease components. Lease expense is recognized on a straight-line basis over the lease term. Variable lease expense primarily represents payments such as common area maintenance, real estate taxes, and utilities and are recognized as expense in the period when those payments are incurred. Short-term lease expense relates to leases with an initial term of 12 months or less. The Corporation has elected to not record a right-of-use asset or lease liability for short-term leases.

As a member of the FHLB of Pittsburgh, the Corporation is required to purchase and hold stock in the FHLB to satisfy membership and borrowing requirements. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is unlike other investment securities insofar as there is no trading market for FHLB stock and the transfer price is determined by FHLB membership rules and not by market participants.

FHLB stock is held as a long-term investment, is valued at its cost basis and is analyzed for impairment based on the ultimate recoverability of the par value. The Company evaluates impairment quarterly. The decision of whether impairment exists is a matter of judgment that reflects our view of the FHLB’s long-term performance, which includes factors such as the following:

Goodwill resulting from business combinations prior to January 1, 2009 represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009 is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interest in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exists that indicate that a goodwill impairment test should be performed. The Corporation has no intangible assets with an indefinite useful life.

Other intangible assets consist of core deposit intangible assets arising from the acquisition of FC Banc Corp. in 2013, Lake National Bank in 2016 and Bank of Akron in 2020. The core deposit intangible assets from these acquisitions are amortized using an accelerated method over their estimated useful lives, which range from four years to ten years, respectively.

Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.

At the inception of a derivative contract, the Corporation designates the derivative as one of three types based on the Corporation's intentions and belief as to likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment ("fair value hedge"), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability ("cash flow hedge"), or (3) an instrument with no hedging designation ("stand-alone derivative"). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in current earnings as fair values change. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as non-interest income.

Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in non-interest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged.

The Corporation formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Corporation also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Corporation discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended.

When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as non-interest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings.

The Corporation is exposed to losses if a counterparty fails to make its payments under a contract in which the Corporation is in the net receiving position. The Corporation anticipates that the counterparties will be able to fully satisfy their obligations under the agreements. All the contracts to which the Corporation is a party settle monthly or quarterly. In addition, the Corporation obtains collateral above certain thresholds of the fair value of its hedges for each counterparty based upon their credit standing and the Corporation has netting agreements with the dealers with which it does business.

Compensation cost is recognized for restricted stock awards issued to employees, based on the fair value of these awards at the date of grant. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. The Corporation's accounting policy is to recognize forfeitures as they occur.

Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized.

A tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded.

Post retirement obligation expense is the net of service and interest cost, return on plan assets and amortization of gains and losses not immediately recognized. The Corporation’s expense associated with its 401(k) plan is determined under the provisions of the plan document and includes both matching and profit sharing components. Deferred compensation and supplemental retirement plan expenses allocate the benefits over years of service.

Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Diluted earnings per common share is computed using the weighted average number of common shares determined for the basic computation plus the dilutive effect of potential common shares issuable under certain stock compensation plans. Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are included in the computation of earnings per share pursuant to the two-class method. The Corporation has determined that its outstanding non-vested time-based restricted stock awards are participating securities.

The Corporation presents comprehensive income as part of the Consolidated Statements of Income and Comprehensive Income. Other comprehensive income and loss consists of unrealized holding gains and losses on the available for sale securities portfolio, changes in the unrecognized actuarial gain and transition obligation related to the Corporation’s post retirement benefits plans, and changes in the fair value of the Corporation’s interest rate swaps, net of tax.

Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the financial statements.

Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.

On January 1, 2020, the Corporation adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the CECL methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments. standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with Topic 842 on leases. In addition, ASC 326 made changes to the accounting for available-for-sale debt securities. One such change is to require credit losses to be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell or believes that it is more likely than not they will be required to sell.

The Corporation adopted ASC 326 using the modified retrospective approach method for all financial assets measured at amortized cost and OBS credit exposures. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. In conjunction with the adoption of CECL, the Corporation has revised its segmentation to align with the methodology applied in determining the ACL for loans under CECL, which is based on federal call report codes which classify loans based on the primary collateral supporting the loan. Segmentation prior to the adoption of CECL was based on product type or purpose.

Upon adoption, the Corporation's total allowance for credit losses increased by $5.0 million, or 25.5%. The increase in the total allowance for credit losses resulted in a $3.4 million decrease to retained earnings, net of deferred taxes. The overall change in total allowance for credit losses upon adoption was primarily due to the move to a life of loan reserve estimate as well as methodology changes required under CECL.

The Corporation adopted ASC 326 using the prospective transition approach for financial assets purchased with credit deterioration that were previously classified as purchased credit impaired ("PCI") and accounted for under ASC 310-30. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2020, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $670 thousand of the allowance for credit losses. The remaining noncredit discount (based on the adjusted amortized cost basis) will be accreted into interest income at the effective interest rate as of January 1, 2020.

In August 2018, the FASB issued ASU 2018-14, "Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans." ASU 2018-14 amends ASC 715-20, "Compensation - Retirement Benefits - Defined Benefit Plans - General." The amended guidance modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated Other Comprehensive Income expected to be recognized in net periodic benefit costs over the next fiscal year, and (b) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for post-retirement health care benefits. Additional disclosures include descriptions of significant gains and losses affecting the benefit obligation for the period. ASU 2018-14 was effective for the Corporation on January 1, 2021 and did not have a material impact on the Corporation's financial statement disclosures.

In December 2019, the FASB issued ASU 2019-12 "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." These amendments remove specific exceptions to the general principles in Topic 740 in GAAP. It eliminates the need for an organization to analyze whether the following apply in a given period: exception to the incremental approach for intraperiod tax allocation; exceptions to accounting for basis differences where there are ownership changes in foreign investments; and exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. It also improves financial statement preparers' application of income tax- related guidance and simplifies GAAP for: franchise taxes that are partially based on income; transactions with a government that result in a step up in the tax basis of goodwill; separate financial statements of legal entities that are not subject to tax; and enacts changes in tax laws in interim periods. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted. ASU 2019-12 was effective for the Corporation on January 1, 2021 and did not have a material impact on the Corporation's financial statements.

In January 2020, the FASB issued ASU 2020-01 - Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. ASU 2020-01 represents changes to clarify certain interactions between the guidance to account for certain equity securities under Topic 321, the guidance to account for investments under the equity method of accounting in Topic 323, and the guidance in Topic 815. These amendments improve current U.S. GAAP by reducing diversity in practice and increasing comparability of the accounting for these transactions. ASU 2020-01 was effective for the Corporation on January 1, 2021 and did not have a material impact on the Corporation's financial statement disclosures.

In March 2020, the FASB issued ASU 2020-04, - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides optional expedients and exceptions for accounting related to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 applies only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform and do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. ASU 2020-04 was effective upon issuance and generally can be applied through December 31, 2022. The adoption of ASU 2020-04 did not have a material impact on the Corporation's financial statement disclosures.

In October 2020, the FASB issued ASU 2020-08 - Codification Improvements to Subtopic 310-20, Receivables - Nonrefundable Fees and Other Costs. ASU 2020-08 clarifies that an entity should reevaluate whether a callable debt security is within the scope of paragraph 310-20-35-33 for each reporting period. ASU 2020-08 was effective for the Corporation on January 1, 2021 and did not have a material impact on the Corporation's financial statement disclosures.

In August 2021, FASB issued ASU 2021-06 - Presentation of Financial Statements (Topic 205), Financial Services—Depository and Lending (Topic 942), and Financial Services—Investment Companies (Topic 946). ASU 2021-06 updates the codification to align with SEC Final Rule Releases No. 33-10786 and No. 33-10835. Specific to financial institutions, these SEC releases updated required annual statistical disclosures. The amendments in ASU 2021-06 were effective immediately. The updates to the statistical disclosures are reflected in the Corporation's Annual Report on Form 10-K for the fiscal year ending December 31, 2021, to align with this guidance.

In March 2020, the FASB issued ASU 2020-04, - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides optional expedients and exceptions for accounting related to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 applies only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform and do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022. The Corporation is currently evaluating the impact of the reference rate reform on the Corporation's consolidated financial statements.

In January 2021, the FASB issued ASU 2021-01 - Reference Rate Reform (Topic 848). ASU 2021-01 expands and clarifies the scope of ASU No. 2020-04 to include derivatives affected by changes in interest rates used for margining, discounting, or contract price alignment, commonly referred to as the “discounting transaction.” Derivatives impacted by the discounting transaction will be eligible for certain optional expedients and exceptions related to contract modifications and hedge accounting as defined in Topic 848. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022. The Corporation is currently evaluating the impact of the reference rate reform on the Corporation's consolidated financial statements.
