Accounting Policies [Abstract]
Accounting Policies	Accounting Policies 1st Source Corporation is a bank holding company headquartered in South Bend, Indiana that provides, through its subsidiaries (collectively referred to as “1st Source” or “the Company”), a broad array of financial products and services. 1st Source Bank (“Bank”), its banking subsidiary, offers commercial and consumer banking services, trust and wealth advisory services, and insurance to individual and business clients. The following is a summary of significant accounting policies followed in the preparation of the consolidated financial statements. Basis of Presentation — The financial statements consolidate 1st Source, its subsidiaries (principally the Bank) and any variable interest entities (“VIEs”) for which the Company has concluded it has significant involvement in and the ability to direct the activities that impact the entity’s economic performance. All significant intercompany balances and transactions have been eliminated. For purposes of the parent company only financial information presented in Note 22, investments in subsidiaries are carried at equity in the underlying net assets. Use of Estimates in the Preparation of Financial Statements — Financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) require the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. Business Combinations — Business combinations are accounted for under the purchase method of accounting. Under the purchase method, assets and liabilities of the business acquired are recorded at their estimated fair values as of the date of acquisition with any excess of the cost of the acquisition over the fair value of the net tangible and intangible assets acquired recorded as goodwill. Results of operations of the acquired business are included in the income statement from the date of acquisition. Cash Flows — For purposes of the consolidated and parent company only statements of cash flows, the Company considers cash and due from banks, federal funds sold and interest bearing deposits with other banks with original maturities of three months or less as cash and cash equivalents. Securities — Securities that the Company has the ability and positive intent to hold to maturity are classified as investment securities held-to-maturity. Held-to-maturity investment securities, when present, are carried at amortized cost. As of December 31, 2021 and 2020, the Company held no securities classified as held-to-maturity. Securities that may be sold in response to, or in anticipation of, changes in interest rates and resulting prepayment risk, or for other factors, are classified as available-for-sale and are carried at fair value. Unrealized gains and losses on debt securities are reported, net of applicable taxes, as a separate component of accumulated other comprehensive income (loss) in shareholders’ equity. Unrealized gains and losses on equity securities are reflected, net of applicable taxes, in earnings. For available-for-sale securities in an unrealized loss position, the Company 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 these criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value in Other Income on the Consolidated Statements of Income. For debt securities that do not meet the aforementioned criteria, the Company 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, nature of the security, the underlying collateral, and the financial condition of the issuer, among other factors. If this assessment indicates 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 the cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for available-for-sale securities 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 available-for-sale securities losses is recognized in other comprehensive income. Changes in the allowance for available-for-sale securities are recorded as a component of credit loss expense. Losses are charged against the allowance for available-for-sale securities losses when management believes the uncollectibility of an available-for-sale security is confirmed or when either criteria regarding intent or requirement to sell is met. Debt and equity securities that are purchased and held principally for the purpose of selling them in the near term are classified as trading account securities and are carried at fair value with unrealized gains and losses reported in earnings. Realized gains and losses on the sales of all securities are reported in earnings and computed using the specific identification cost basis. Other investments consist of shares of Federal Home Loan Bank of Indianapolis (FHLBI) and Federal Reserve Bank stock. As restricted member stocks, these investments are carried at cost. Both cash and stock dividends received on the stocks are reported as income. Quarterly, the Company reviews its investment in FHLBI for impairment. Factors considered in determining impairment are: history of dividend payments; determination of cause for any net loss; adequacy of capital; and review of the most recent financial statements. As of December 31, 2021 and 2020, it was determined that the Company’s investment in FHLBI stock is appropriately valued at cost, which equates to par value. In addition, other investments include interest bearing deposits with other banks with original maturities of greater than three months. These investments are in denominations, including accrued interest, that are fully insured by the FDIC. Loans and Leases — Loans are stated at the principal amount outstanding, net of unamortized deferred loan origination fees and costs and net of unearned income. Interest income is accrued as earned based on unpaid principal balances. Origination fees and direct loan and lease origination costs are deferred, and the net amount amortized to interest income over the estimated life of the related loan or lease. Loan commitment fees are deferred and amortized into other income over the commitment period. Direct financing leases are carried at the aggregate of lease payments plus estimated residual value of the leased property, net of unamortized deferred lease origination fees and costs and unearned income. Interest income on direct financing leases is recognized over the term of the lease to achieve a constant periodic rate of return on the outstanding investment. Effective January 1, 2019, as part of the new leasing standard, only those costs incurred as a direct result of closing a lease transaction are capitalized. All existing deferrals will continue to be amortized over the estimated life of the lease while all new initial direct costs are expensed immediately. Accrued interest is included in Accrued Income and Other Assets on the Consolidated Statements of Financial Condition. The accrual of interest on loans and leases is discontinued when a loan or lease becomes contractually delinquent for 90 days, or when an individual analysis of a borrower’s credit worthiness indicates a credit should be placed on nonperforming status, except for residential mortgage loans and consumer loans that are well secured and in the process of collection. Residential mortgage loans are placed on nonaccrual at the time the loan is placed in foreclosure. When interest accruals are discontinued, interest credited to income in the current year is reversed and interest accrued in the prior year is charged to the allowance for loan and lease losses. However, in some cases, the Company may elect to continue the accrual of interest when the net realizable value of collateral is sufficient to cover the principal and accrued interest. When a loan or lease is classified as nonaccrual and the future collectability of the recorded loan or lease balance is doubtful, collections on interest and principal are applied as a reduction to principal outstanding. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured, which is typically evidenced by a sustained repayment performance of at least six months. Loans and leases that have been modified and economic concessions have been granted to borrowers who have experienced financial difficulties are considered a troubled debt restructuring (TDR). These concessions typically result from the Company’s loss mitigation activities and may include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. Certain TDRs are classified as nonperforming at the time of restructuring and typically are returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period of at least six months. When the Company modifies loans and leases in a TDR, it evaluates any possible impairment based on the present value of expected future cash flows, discounted at the contractual interest rate of the original loan or lease agreement, or uses the current fair value of the collateral, less selling costs for collateral dependent loans. If the Company determines that the value of the modified loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through an allowance for loan and lease losses estimate or a charge-off to the allowance for loan and lease losses. In periods subsequent to modification, the Company evaluates all TDRs, including those that have payment defaults, for possible impairment and recognizes impairment through the allowance for loan and lease losses. On March 27, 2020, the President of the United States signed the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), which provides entities with optional temporary relief from certain accounting and financial reporting requirements under U.S. GAAP. Section 4013 of the CARES Act allows financial institutions to suspend application of certain TDR accounting guidance for loan and lease modifications related to the COVID-19 pandemic made between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the end of the COVID-19 national emergency, provided certain criteria are met. Section 4013 of the CARES Act was amended on December 27, 2020 to extend this relief until January 1, 2022. The relief can be applied to loan and lease modifications for borrowers that were not more than 30 days past due as of December 31, 2019 and to loan and lease modifications that defer or delay the payment of principal or interest, or change the interest rate on the loan. The Company chose to apply this relief to eligible loan and lease modifications. At December 31, 2021 and December 31, 2020, loan and lease modification balances related to the COVID-19 pandemic were $0 million and $129 million, respectively. The Company sells mortgage loans to the Government National Mortgage Association (GNMA) in the normal course of business and retains the servicing rights. The GNMA programs under which the loans are sold allow the Company to repurchase individual delinquent loans that meet certain criteria from the securitized loan pool. At its option, and without GNMA’s prior authorization, the Company may repurchase a delinquent loan for an amount equal to 100% of the remaining principal balance on the loan. Once the Company has the unconditional ability to repurchase a delinquent loan, the Company is deemed to have regained effective control over the loan and the Company is required to recognize the loan on its balance sheet and record an offsetting liability, regardless of its intent to repurchase the loan. At December 31, 2021 and 2020, residential real estate portfolio loans included $1.33 million and $2.31 million, respectively, of loans available for repurchase under the GNMA optional repurchase programs with the offsetting liability recorded within other short-term borrowings. Mortgage Banking Activities — Loans held for sale are composed of performing one-to-four family residential mortgage loans originated for resale. Mortgage loans originated with the intent to sell are carried at fair value. The Company recognizes the rights to service mortgage loans for others as separate assets, whether the servicing rights are acquired through a separate purchase or through the sale of originated loans with servicing rights retained. The Company allocates a portion of the total proceeds of a mortgage loan to servicing rights based on the relative fair value. These assets are amortized as reductions of mortgage servicing fee income over the estimated servicing period in proportion to the estimated servicing income to be received. The balance of MSRs is located in Accrued Income and Other Assets on the Consolidated Statements of Financial Condition and the gains and losses on the sale of MSRs are recognized in Noninterest Income on the Consolidated Statements of Income in the period in which such rights are sold. MSRs are evaluated for impairment at each reporting date. For purposes of impairment measurement, MSRs are stratified based on the predominant risk characteristics of the underlying servicing, principally by loan type. If temporary impairment exists within a tranche, a valuation allowance is established through a charge to income equal to the amount by which the carrying value exceeds the fair value. If it is later determined all or a portion of the temporary impairment no longer exists for a particular tranche, the valuation allowance is reduced through a recovery of income. MSRs are also reviewed for permanent impairment. Permanent impairment exists when recoverability of a recorded valuation allowance is determined to be remote considering historical and projected interest rates, prepayments, and loan pay-off activity. When this situation occurs, the unrecoverable portion of the valuation allowance is applied as a direct write-down to the carrying value of the MSRs. Unlike a valuation allowance, a direct write-down permanently reduces the carrying value of the MSRs and the valuation allowance, precluding subsequent recoveries. As part of mortgage banking operations, the Company enters into commitments to originate loans whereby the interest rate on these loans is determined prior to funding (“rate lock commitments”). Similar to loans held for sale, the fair value of rate lock commitments is subject to change primarily due to changes in interest rates. Under the Company’s risk management policy, these fair values are hedged primarily by selling forward contracts on agency securities at the time the interest rate locks are issued to the customers. The rate lock commitments on mortgage loans intended to be sold and the related hedging instruments are recorded at fair value with changes in fair value recorded in current earnings. Allowance for Credit Losses: Loans and leases — Accrued interest on loans and leases is excluded from the calculation of the allowance for credit losses due to the Company’s charge-off policy to reverse accrued interest on nonperforming loans against interest income in a timely manner. Expected credit losses on net investments in leases, including any unguaranteed residual asset, are included in the allowance for loan and lease losses. Allowance for Loan and Lease Losses — Effective January 1, 2020, the allowance for credit losses is established for current expected credit losses on the Company’s loan and lease portfolio. Prior to January 1, 2020, the allowance was established based on an incurred loss model. It is the Company’s policy to maintain the allowance at a level believed to be adequate to absorb estimated credit losses within its portfolio of loans and leases. The determination of the allowance requires significant judgment to estimate credit losses measured on a collective pool basis when similar risk characteristics exist, and for loans evaluated individually. In determining the allowance, the Company estimates expected future losses for the loan’s entire contractual term adjusted for expected payments when appropriate. The allowance estimate considers relevant available information, from internal and external sources relating to the historical loss experience, current conditions, and reasonable and supportable forecasts for the Company’s outstanding loan and lease balances. The allowance is an estimation that reflects management’s evaluation of expected losses related to the Company’s financial assets measured at amortized cost. To ensure that the allowance is maintained at an adequate level, a detailed analysis is performed on a quarterly basis and an appropriate provision is made to adjust the allowance. The Company categorizes its loan portfolios into nine segments based on similar risk characteristics. Loans within each segment are collectively evaluated using either: 1) a cohort cumulative loss rate methodology (“cohort”) or, 2) the probability of default (“PD”)/loss given default (“LGD”) methodology (PD/LGD). The cohort methodology is applied to ungraded portfolios, portfolios where receipt of financial statements is generally less timely, and portfolios where there are numerous small dollar accounts that are credit scored. Loans are broken out by internal risk rating (loan grade) bands: 1-6 and 7-12 (special attention). For ungraded portfolios, there is only one pool. The cohort methodology has a steady state assumption; qualitative adjustments capture any differences that may exist between the current and historical conditions. The PD/LGD methodology is applied to graded portfolios due to the quantitative nature of the Company’s risk rating system and is consistent with the Company’s definition of risk, downgrading a credit where and when appropriate and recognizing losses in a timely manner. Loans are broken out by risk rating (loan grade) bands: 1-3, 4-6, 7-8, and 9-12. The amortized cost loan balances (rather than counts) are used for determining the transition and default probabilities. The Company uses risk rating bands as the active state to track the movement of loans through the transition matrix. The transition frequency is quarterly. Default is defined as the point at which a loan is placed on non-accrual status. In addition, a charge-off is assumed to be a default (i.e. a loan goes from accruing to charge-off, without ever being on non-accrual status). The PD is the cumulative probability of default estimated by use of a transition matrix (based on a Markov transition matrix methodology) which captures the migration of a loan from one risk rating band to another. The LGD is the ratio of loss relative to the exposure (amortized cost) at default. The current expected credit loss methodology has a factor for reasonable and supportable forecasts. Generally, reasonable and supportable forecasts are for two years or less and have a reversion period of a similar duration, reverting expected credit losses to a level that is consistent with our historical loss experience. Forecast adjustments are added via basis points for the cohort methodology. For the PD/LGD methodology, adjustments to the probability of default factor are applied through forecast adjustments to the PD factor used as the baseline transition matrix runout, thus impacting the historical loss ratio. The Company developed its reasonable and supportable forecasts using relevant data including, but not limited to, growth in gross domestic product, unemployment rates, housing market trends, commodity prices, inflation, and other factors associated with credit losses on the financial statements. For both the cohort and the PD/LGD methodologies, the Company uses qualitative adjustments to capture differences that may exist between the current and historical conditions. Qualitative factors include but are not limited to current market risk assessment by industry, recent loss experience in particular segments of the portfolios, movement in equipment values collateralizing specialized industry portfolios, concentrations of credit risk, delinquencies, trends in volume, experience and depth of relationship managers and division management, and the effects of changes in lending policies and practices, including changes in quality of the loan and lease origination, servicing and risk management process. Loans which exhibit different risk characteristics than the pool are evaluated individually for impairment. Loans evaluated individually are not included in the collective evaluation. These loans can be identified from a variety of sources including delinquency, non-accrual status and troubled debt restructurings (TDRs). The scope may include accruing loans that exhibit risk characteristics which differ from their pool or non-performing loans with risk characteristics not similar to other special attention loans in their pool. Individual reserves are determined based on an analysis of the loan’s expected future cash flows, the loan’s observable market value, or the fair value of the collateral less costs to sell. When foreclosure is probable, impairment is determined based on the collateral’s fair value less costs to sell. As a practical expedient, fair value less costs to sell may be used when developing the estimate of credit losses. Similarly, for a going concern analysis, a discounted cash method may be used. Liability for Credit Losses on Unfunded Loan Commitments — The liability for credit losses on commitments to originate loans and standby letters of credit is included in Accrued Expenses and Other Liabilities on the Consolidated Statements of Financial Condition. Expected credit losses are estimated over the contractual period in which the Company is exposed to credit risk via a contractual obligation unless the obligation is unconditionally cancellable by the Company. The liability for credit losses on unfunded loan commitments is adjusted as a provision for credit losses in Other Noninterest Expense on the Consolidated Statements of Income. 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 useful life. Because business processes and credit risks associated with unfunded credit commitments are essentially the same as for loans, the Company utilizes similar processes to estimate its liability for unfunded credit commitments. Equipment Owned Under Operating Leases — As a lessor, the Company finances various types of construction equipment, medium and heavy duty trucks, automobiles and other equipment under leases classified as operating leases. The equipment underlying the operating leases is reported at cost, net of accumulated depreciation, on the Consolidated Statements of Financial Condition. These operating lease arrangements require the lessee to make a fixed monthly rental payment over a specified lease term generally ranging from three years to seven years. Revenue consists of the contractual lease payments and is recognized on a straight-line basis over the lease term and reported in Noninterest Income on the Consolidated Statements of Income. Leased assets are depreciated on a straight-line method over the lease term to the estimate of the equipment’s fair market value at lease termination, also referred to as “residual” value. The depreciation of these operating lease assets is reported in Noninterest Expense on the Consolidated Statements of Income. For automobile leases, fair value is based upon published industry market guides. For other equipment leases, fair value may be based upon observable market prices, third-party valuations, or prices received on sales of similar assets at the end of the lease term. These residual values are reviewed annually to ensure the recorded amount does not exceed the fair market value at the lease termination. At the end of the lease, the operating lease asset is either purchased by the lessee or returned to the Company. The Company is responsible for the payment of personal property taxes which is reported in Other Expense on the Consolidated Statements of Income. The lessee is responsible for reimbursing the Company for personal property taxes which is reported in Other Income on the Consolidated Statements of Income. The Company excludes sales taxes and other similar taxes from being reported as lease revenue with an associated expense. Lease Commitments — The Company leases certain banking center locations, office space, land and billboards. In determining whether a contract contains a lease, the Company examines the contract to ensure an asset was specifically identified and that the Company has control of use over the asset. To determine whether a lease is classified as operating or finance, the Company performs an economic life test on all building leases with greater than a twenty years term. Further, the Company performs a fair value test to identify any leases that have a present value of future lease payments over the lease term that is greater than 90% of the fair value of the building. The Company only capitalizes leases with an initial lease liability of $2,000 or greater. At lease inception, the Company determines the lease term by adding together the minimum lease term and all optional renewal periods that it is reasonably certain to renew. The Company determines this on each lease by considering all relevant contract-based, asset-based, market-based, and entity-based economic factors. Generally, the exercise of lease renewal options is at the Company’s sole discretion. The lease term is used to determine whether a lease is operating or finance and is used to calculate straight-line rent expense. Additionally, the depreciable life of leasehold improvements is limited by the expected lease term. Operating lease rentals are expensed on a straight-line basis over the life of the lease beginning on the date the Company takes possession of the property. Rent expense and variable lease costs are included in Net Occupancy Expense on the Consolidated Statements of Income. Included in variable lease costs are leases with rent escalations based on recent financial indices, such as the Consumer Price Index, where the Company initially measures lease payments using the index on the commencement date and records future changes in rent payments resulting from changes in the index to variable costs in the period the changes occur. Certain leases require the Company to pay common area maintenance, real estate taxes, insurance and other operating expenses associated with the leases premises. These expenses are classified in Net Occupancy Expense on the Consolidated Statements of Income, consistent with similar costs for owned locations. There are no residual value guarantees, restrictions or covenants imposed by leases. The Company accounts for lease and nonlease components together as a single lease component by class of underlying asset. Operating lease obligations with an initial term longer than 12 months are recorded with a right of use asset and a lease liability on the Consolidated Statements of Financial Condition. The discount rate used in determining the lease liability and related right of use asset is based upon what would be obtained by the Company for similar loans as an incremental rate as of the date of origination or renewal. Other Real Estate — Other real estate acquired through partial or total satisfaction of nonperforming loans is included in Other Assets on the Consolidated Statements of Financial Condition and recorded at fair value less anticipated selling costs based upon the property’s appraised value at the date of transfer, with any difference between the fair value of the property less cost to sell, and the carrying value of the loan charged to the allowance for loan and lease losses or other income, if a positive adjustment. Subsequent fair value write-downs or write-ups, to the extent of previous write-downs, property maintenance costs, and gains or losses recognized upon the sale of other real estate are recognized in Noninterest Expense on the Consolidated Statements of Income. Gains or losses resulting from the sale of other real estate are recognized on the date of sale. As of December 31, 2021 and 2020, other real estate had carrying values of $0.00 million and $0.36 million, respectively, and is included in Other Assets on the Consolidated Statements of Financial Condition. Repossessed Assets — Repossessed assets may include fixtures and equipment, inventory and receivables, aircraft, construction equipment, and vehicles acquired from business banking and specialty finance activities. Repossessed assets are included in Other Assets on the Consolidated Statements of Financial Condition at fair value of the equipment or vehicle less estimated selling costs. At the time of repossession, the recorded amount of the loan or lease is written down to the fair value of the equipment or vehicle by a charge to the allowance for loan and lease losses or other income, if a positive adjustment. Subsequent fair value write-downs or write-ups, to the extent of previous write-downs, equipment maintenance costs, and gains or losses recognized upon the sale of repossessions are recognized in Noninterest Expense on the Consolidated Statements of Income. Gains or losses resulting from the sale of repossessed assets are recognized on the date of sale. Repossessed assets totaled $0.86 million and $1.98 million, as of December 31, 2021 and 2020, respectively, and are included in Other Assets on the Consolidated Statements of Financial Condition. Premises and Equipment — Premises and equipment are stated at cost, less accumulated depreciation and amortization. The provision for depreciation is computed by the straight-line method, primarily with useful lives ranging from three years to 31.5 years. Maintenance and repairs are charged to expense as incurred, while improvements, which extend the useful life, are capitalized and depreciated over the estimated remaining life. Goodwill and Intangibles — Goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets acquired. Other intangible assets represent purchased assets that also lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Goodwill is reviewed for impairment at least annually or on an interim basis if an event occurs or circumstances change that would more likely than not reduce the carrying amount. Goodwill is allocated into two reporting units. Fair value for each reporting unit is estimated using stock price multiples or earnings before interest, tax, depreciation and amortization (EBITDA) multiples. Intangible assets that have finite lives are amortized over their estimated useful lives and are subject to impairment testing. All of the Company’s other intangible assets have finite lives and are amortized on a straight-line basis over varying periods not exceeding twenty-five years. The Company has historically evaluated goodwill for impairment during the fourth quarter of each year, with financial data as of September 30. During the first quarter of 2020, management determined that the deterioration in general economic conditions as a result of the COVID-19 pandemic and responses thereto represented a triggering event prompting an evaluation of goodwill impairment. The Company performed impairment analyses in each quarter of 2020. In 2021, management determined conditions no longer represented a triggering event requiring quarterly analyses and returned to its historical practice of evaluating goodwill during th

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Presentation of Financial Statements: In August 2021, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2021-06 “Presentation of Financial Statements (Topic 205), Financial Services—Depository and Lending (Topic 942), and Financial Services—Investment Companies (Topic 946): Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants.” This ASU amends the SEC sections of the Codification related to Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update to Statistical Disclosures for Bank and Savings and Loan Registrants. The guidance is effective upon its addition to the FASB codification. The adoption of ASU 2021-06 did not have a material impact on its disclosures. Reference Rate Reform: In March 2020, the FASB issued ASU No. 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” These amendments provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. In January 2021, the FASB issued ASU 2021-01 which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. The Company continues to implement its transition plan towards cessation of LIBOR and the modification of its loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR. The Company expects to utilize the LIBOR transition relief allowed under ASU 2020-04 and ASU 2021-01, as applicable, and does not expect such adoption to have a material impact on its accounting and disclosures. The Company will continue to assess the impact as the reference rate transition approaches June 30, 2023.

Receivables [Abstract]
Loan and Lease Financings	Loan and Lease Financings Total loans and leases outstanding were recorded net of unearned income and deferred loan fees and costs at December 31, 2021 and 2020, and totaled $5.35 billion and $5.49 billion, respectively. At December 31, 2021 and 2020, net deferred loan and lease (fees) costs were $(0.09) million and $(3.73) million, respectively. At December 31, 2021 and 2020, there were $2.71 million and $6.37 million, respectively, in deferred loan fees related to Paycheck Protection Program (PPP) loans. Accrued interest receivable on loans and leases at December 31, 2021 and 2020 was $12.94 million and $16.39 million, respectively. In the ordinary course of business, the Company has extended loans to certain directors, executive officers, and principal shareholders of equity securities of 1st Source and to their affiliates. In the opinion of management, these loans are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with persons not related to the Company and did not involve more than the normal risk of collectability, or present other unfavorable features. The loans are consistent with sound banking practices and within applicable regulatory and lending limitations. The aggregate dollar amounts of these loans were $14.05 million and $26.51 million at December 31, 2021 and 2020, respectively. During 2021, $4.71 million of new loans and other additions were made and $17.17 million of repayments and other reductions occurred. The Company evaluates loans and leases for credit quality at least annually but more frequently if certain circumstances occur (such as material new information which becomes available and indicates a potential change in credit risk). The Company uses two methods to assess credit risk: loan or lease credit quality grades and credit risk classifications. The purpose of the loan or lease credit quality grade is to document the degree of risk associated with individual credits as well as inform management of the degree of risk in the portfolio taken as a whole. Credit risk classifications are used to categorize loans by degree of risk and to designate individual or committee approval authorities for higher risk credits at the time of origination. Credit risk classifications include categories for: Acceptable, Marginal, Special Attention, Special Risk, Restricted by Policy, Regulated and Prohibited by Law. All loans and leases, except residential real estate and home equity loans and consumer loans, are assigned credit quality grades on a scale from 1 to 12 with grade 1 representing superior credit quality. The criteria used to assign grades to extensions of credit that exhibit potential problems or well-defined weaknesses are primarily based upon the degree of risk and the likelihood of orderly repayment, and their effect on our safety and soundness. Loans or leases graded 7 or weaker are considered “special attention” credits and, as such, relationships in excess of $250,000 are reviewed quarterly as part of management’s evaluation of the appropriateness of the allowance for loan and lease losses. Grade 7 credits are defined as “watch” and contain greater than average credit risk and are monitored to limit our exposure to increased risk; grade 8 credits are “special mention” and, following regulatory guidelines, are defined as having potential weaknesses that deserve management’s close attention. Credits that exhibit well-defined weaknesses and a distinct possibility of loss are considered ‘‘classified’’ and are graded 9 through 12 corresponding to the regulatory definitions of “substandard” (grades 9 and 10) and the more severe ‘‘doubtful’’ (grade 11) and ‘‘loss’’ (grade 12). For residential real estate and home equity and consumer loans, credit quality is based on the aging status of the loan and by payment activity. Nonperforming loans are those loans which are on nonaccrual status or are 90 or more past due. Below is a summary of the Company’s loan and lease portfolio segments and a discussion of the risk characteristics relevant to each portfolio segment. Commercial and agricultural – loans are to entities within the Company’s local market communities. Loans are for business or agri-business purposes and include working capital lines of credit secured by accounts receivable and inventory that are generally renewable annually and term loans secured by equipment with amortizations based on the expected life of the underlying collateral, generally three Solar – loans are for the purpose of financing solar related projects and may include construction draw notes, operating loans, letters of credit and may entail a tax equity structure. Collateral in a multi-state area includes tangible assets of the borrower, assignment of intangible assets including power purchase agreements, and pledges of permits and licenses. Financing is provided to qualified borrowers throughout the continental United States with an emphasis on the region east of the Rocky Mountains. Auto and light truck – loans are secured by vehicles and borrowers are nationwide. The portfolio consists of multiple industries: auto rental, auto leasing and specialty vehicle which includes bus, funeral car and step van. Borrowers in the auto rental segment are primarily independent auto rental entities with on-airport and off-airport locations, and some insurance replacement business. Loan amortizations are relatively short, generally eighteen months, but up to four years. Auto leasing customers lease to businesses and the Company takes assignment of the lease stream and places its lien on the vehicles. Terms are generally longer than the auto rental sector, three Medium and heavy duty truck – loans and full-service truck leases are secured by heavy-duty trucks, commonly Class 8 trucks, and are generally personally guaranteed. In addition to economic risks, collateral risk is significant. Financing is generally at full cost, plus additional expenditures to get the vehicle operational, such as taxes, insurance and fees. It takes three Aircraft – loans are to domestic and foreign borrowers with the domestic segment further divided into two pools: 1) personal and business use, and 2) dealers and operators. The Company’s focus for the foreign sector is Latin America, principally Mexico and Brazil. Loans are primarily secured by new and used business jets and helicopters, with appropriate advances, amortizations of ten Construction equipment – loans are to borrowers throughout the country secured by specific equipment. The borrowers include highway and road builders, asphalt producers and pavers, suppliers of aggregate products, site developers, frac sand operations, general construction equipment dealers and operators, and crane rental entities. Generally, loans include personal guarantees. The construction equipment industry is heavily dependent on the U.S. economy and the global economy. Market growth is reliant on investments from public and private sectors into urbanization and infrastructure projects. Commercial real estate – loans are generally to entities within the local market communities served by the Company with advances generally within regulatory guidelines. Historically, the Company’s exposure to commercial real estate had been primarily to the less risky owner-occupied segment although growth in recent years has been in the non-owner-occupied segment which now accounts for slightly less than half of the portfolio. The non-owner-occupied segment includes hotels, apartment complexes and warehousing facilities. There is limited exposure to construction loans. Many commercial real estate loans carry personal guarantees. Additional risks in the commercial real estate portfolio stem from geographical concentration in northern Indiana and southwest Michigan and general economic conditions. Residential real estate and home equity – loans predominantly include one-to-four family mortgages to borrowers in the Company’s local market communities and are appropriately underwritten and secured by residential real estate. Consumer – loans are to individuals in the Company’s local markets and auto loans are generally secured by personal vehicles and appropriately underwritten. The following table shows the amortized cost of loans and leases, segregated by portfolio segment, credit quality rating and year of origination as of December 31, 2021.

The classification between nonperforming and performing is shown at the time of modification. Modification programs focused on extending maturity dates or modifying payment patterns with most TDRs experiencing a combination of concessions. The modifications did not result in the contractual forgiveness of principal or interest. The TDRs during 2020 were the result of issues that predated the COVID-19 pandemic. There was one modification during 2021, two modification during 2020, and one modification during 2019 that resulted in an interest rate reduction below market rate.

Allowance for Credit Losses	Allowance for Credit Losses Allowance for Loan and Lease Losses The methodology used to estimate the appropriate level of the allowance for loan and lease losses is described in Note 1, under the heading “Allowance for Credit Losses.” The allowance for loan and lease losses at December 31, 2021 and 2020, represents the Company’s current estimate of lifetime credit losses inherent in the loan and lease portfolio. The following table shows the changes in the allowance for loan and lease losses, segregated by portfolio segment, for each of the three years ended December 31.

The 2020 allowance includes the impact of adopting ASC 326 for each loan segment. Generally, a decrease in the allowance upon adoption was related to shorter duration assets in the loan class and likewise, an increase was generally due to longer duration assets. Commercial and agricultural – loans declined year-over-year due to PPP debt forgiveness partially offset by modest loan growth in our core businesses. The decline in the allowance was principally due to improved credit quality as reflected by lower special attention loan balances. Solar – allowance increased due to loan growth. Credit quality is stable to improving. Auto and light truck – allowance decreased as a result of charge-offs and lower outstanding loan balances in the higher risk bus segment of the portfolio, which was significantly impacted by the pandemic. The decline in balances in the bus segment was more than offset by increases in the auto rental and leasing segments, which carry lower loss ratios. Medium and heavy duty truck – allowance decrease was principally attributable to a decrease in portfolio outstanding balances. Credit quality metrics continued to be relatively strong for this portfolio. Aircraft – the allowance was principally impacted by improved credit quality metrics and strengthening collateral values somewhat offset by loan growth and heightened economic concerns related to foreign loans. The Company has historically carried a higher allowance in this portfolio due to risk volatility. Construction equipment – allowance increase was driven by loan growth. Commercial real estate – allowance decrease was a result of declines in outstanding loan balances and also qualitative adjustments to the loss ratios for the hotel segment which was hard hit by the pandemic but is currently performing better than anticipated. Residential real estate and home equity – decreased allowance due to decline in loan balances. Consumer – segment saw an increase in allowance due to forecast adjustments and slight loan growth. Economic Outlook As of December 31, 2021, the most significant economic factors impacting our loan portfolios are the pandemic and the Omicron COVID variant surge, ongoing supply chain disruptions, and increasing inflation. The forecast considers global and domestic economic effects from the pandemic as well as other key economic factors such as unemployment and inflation which may impact our clients. The Company’s assumption was that economic growth will slow in 2022 and 2023 and inflation will remain above the 2% Federal Reserve target rate resulting in an adverse impact on the loan and lease portfolio over the next two years. As a result of the unprecedented economic uncertainty caused by the COVID-19 pandemic, the Company’s future loss estimates may vary considerably from the December 31, 2021 assumptions. Liability for Credit Losses on Unfunded Loan Commitments The liability for credit losses inherent in unfunded loan commitments is included in Accrued Expenses and Other Liabilities on the Consolidated Statements of Financial Condition. The following table shows the changes in the liability for credit losses on unfunded loan commitments for each of the three years ended December 31.

Leases [Abstract]
Lease Investments Disclosure Text Block	Lease Investments As a lessor, the Company’s loan and lease portfolio includes direct finance leases, which are included in Commercial and agricultural, Solar, Auto and light truck, Medium and heavy duty truck, Aircraft, and Construction equipment on the Consolidated Statements of Financial Condition. The Company also finances various types of construction equipment, medium and heavy duty trucks, automobiles and other equipment under leases classified as operating leases, which are included in Equipment Owned Under Operating Leases, net, on the Consolidated Statements of Financial Condition. The following table shows the components of the investment in direct finance and operating leases as of December 31.

In addition, a portion of our leases are terminal rental adjustment clause or “TRAC” leases where the lessee effectively guarantees the full residual value through a rental adjustment at the end of term or those where partial value is guaranteed (“split-TRAC”), which has a limited residual risk. Under a split-TRAC structure, the limited residual risk would be satisfied first by the net sale proceeds of the leased asset. The lessee’s at-risk portion, or top risk, is satisfied last and is subject to repayment as additional rent, if the TRAC amount is not satisfied by the net sale proceeds. The carrying amount of residual assets covered by residual value guarantees was $27.33 million and $43.65 million at December 31, 2021 and December 31, 2020, respectively.

Variable Interest Entities

Variable Interest Entities
Variable Interest Entities	Variable Interest Entities A variable interest entity (VIE) is a partnership, limited liability company, trust or other legal entity that meets any one of the following criteria: • The entity does not have sufficient equity to conduct its activities without additional subordinated financial support from another party. • The entity’s investors lack the power to direct the activities that most significantly affect the entity’s economic performance. • The entity’s at-risk holders do not have the obligation to absorb the losses or the right to receive residual returns. • The voting rights of some investors are not proportional to their economic interests in the entity, and substantially all of the entity’s activities involve, or are conducted on behalf of, investors with disproportionately few voting rights. The Company is involved in various entities that are considered to be VIEs. The Company’s investments in VIEs are primarily related to investments promoting affordable housing, community development and renewable energy sources. Some of these tax-advantaged investments support the Company’s regulatory compliance with the Community Reinvestment Act. The Company’s investments in these entities generate a return primarily through the realization of federal and state income tax credits, and other tax benefits, such as tax deductions from operating losses of the investments, over specified time periods. These tax credits are recognized as a reduction of tax expense or, for investments qualifying as investment tax credits, as a reduction to the related investment asset. The Company recognized federal and state income tax credits related to its affordable housing and community development tax-advantaged investments in tax expense of $2.02 million, $1.72 million and $1.55 million for the years ended December 31, 2021, 2020 and 2019, respectively. The Company also recognized $3.53 million, $31.08 million and $15.86 million of investment tax credits for the years ended December 31, 2021, 2020 and 2019, respectively. The Company is not required to consolidate VIEs in which it has concluded it does not have a controlling financial interest, and thus is not the primary beneficiary. In such cases, the Company does not have both the power to direct the entities’ most significant activities and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIEs. As a limited partner in these operating partnerships, we are allocated credits and deductions associated with the underlying properties. The Company has determined that it is not the primary beneficiary of these investments because the general partners have the power to direct activities that most significantly influence the economic performance of their respective partnerships. The Company’s investments in these unconsolidated VIEs are carried in Other Assets on the Consolidated Statements of Financial Condition. The Company’s unfunded capital and other commitments related to these unconsolidated VIEs are generally carried in Other Liabilities on the Consolidated Statements of Financial Condition. The Company’s maximum exposure to loss from these unconsolidated VIEs include the investment recorded on the Consolidated Statements of Financial Condition, net of unfunded capital commitments, and previously recorded tax credits which remain subject to recapture by taxing authorities based on compliance features required to be met at the project level. While the Company believes potential losses from these investments are remote, the maximum exposure was determined by assuming a scenario where the community-based business, housing projects and renewable energy projects completely fail and do not meet certain taxing authority compliance requirements resulting in recapture of the related tax credits. The following table provides a summary of investments in affordable housing, community development and renewable energy VIEs that the Company has not consolidated as of December 31, 2021 and 2020. (Dollars in thousands) 2021 2020 Investment carrying amount $ 35,968 $ 22,742 Unfunded capital and other commitments 29,670 26,716 Maximum exposure to loss 50,319 52,106 The Company is required to consolidate VIEs in which it has concluded it has significant involvement in and the ability to direct the activities that impact the entity’s economic performance. The Company is the managing general partner of entities to which it shares interest in tax-advantaged investments with a third party. At December 31, 2021 and 2020, approximately $59.08 million and $53.61 million, respectively, of the Company’s assets and $0.00 million and $4.93 million, respectively, of its liabilities included on the Consolidated Statements of Financial Condition were related to tax-advantaged investment VIEs which the Company has consolidated. The assets of the consolidated VIE are reported in Other Assets, the liabilities are reported in Other Liabilities and the non-controlling interest is reported in Equity on the Consolidated Statements of Financial Condition. The assets of a particular VIE are the primary source of funds to settle its obligations. The creditors of the VIE do not have recourse to the general credit of the Company. The Company’s exposure to the consolidated VIE is generally limited to the carrying value of its variable interest plus any related tax credits previously recognized. Additionally, the Company sponsors one trust, 1st Source Master Trust (Capital Trust) of which 100% of the common equity is owned by the Company. The Capital Trust was formed in 2007 for the purpose of issuing corporation-obligated mandatorily redeemable capital securities (the capital securities) to third-party investors and investing the proceeds from the sale of the capital securities solely in junior subordinated debenture securities of the Company (the subordinated notes). The subordinated notes held by the Capital Trust are the sole assets of the Capital Trust. The Capital Trust qualifies as a variable interest entity for which the Company is not the primary beneficiary and therefore reported in the financial statements as an unconsolidated subsidiary. The junior subordinated debentures are reflected as subordinated notes on the Consolidated Statements of Financial Condition with the corresponding interest distributions reflected as Interest Expense on the Consolidated Statements of Income. The common shares issued by the Capital Trust are included in Other Assets on the Consolidated Statements of Financial Condition. Distributions on the capital securities issued by the Capital Trust are payable quarterly at a rate per annum equal to the interest rate being earned by the Capital Trust on the subordinated notes held by the Capital Trust. The capital securities are subject to mandatory redemption, in whole or in part, upon repayment of the subordinated notes. The Company has entered into agreements which, taken collectively, fully and unconditionally guarantee the capital securities subject to the terms of each of the guarantees. The capital securities held by the Capital Trust qualify as Tier 1 capital under Federal Reserve Board guidelines. The following table shows subordinated notes at December 31, 2021.

Earnings Per Share

Earnings Per Share	12 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Earnings per common share is computed using the two-class method. 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. Participating securities include non-vested restricted stock awards. Non-vested restricted stock awards are considered participating securities to the extent the holders of these securities receive non-forfeitable dividends at the same rate as holders of common stock. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock compensation using the treasury stock method. Stock options, where the exercise price was greater than the average market price of the common shares, were excluded from the computation of diluted earnings per common share because the result would have been antidilutive. No stock options were considered antidilutive as of December 31, 2021, 2020 and 2019. The following table presents a reconciliation of the number of shares used in the calculation of basic and diluted earnings per common share for the three years ending December 31.

The Plan encourages diversification of investments with opportunities to change investment elections and contribution levels. Employees are eligible to participate in the Plan the first of the month following 90 days of employment. The Company matches dollar for dollar on the first 4% of deferred compensation, plus 50 cents on the dollar of the next 2% deferrals. The Company will also contribute to the Plan an amount designated as a fixed 2% employer contribution. The amount of fixed contribution is equal to two percent of the participant’s eligible compensation. Additionally, each year the Company may, in its sole discretion, make a discretionary profit sharing contribution. As of December 31, 2021 and 2020, there were 751,447 and 824,466 shares, respectively, of 1st Source Corporation common stock held in relation to employee benefit plans. The Company contributions are allocated among the participants on the basis of compensation. Each participant’s account is credited with cash and/or shares of 1st Source common stock based on that participant’s compensation earned during the year. After completing 5 years of service in which they worked at least 1,000 hours per year, a participant will be completely vested in the Company’s contribution. An employee is always 100% vested in their deferral. Plan participants are entitled to receive distributions from their Plan accounts in-service and upon termination of service, retirement, or death. Contribution expense for the years ended December 31, 2021, 2020, and 2019, amounted to $6.31 million, $5.70 million, and $5.48 million, respectively.

Stock Based Compensation

Stock Based Compensation	12 Months Ended

Share-based Payment Arrangement [Abstract]
Stock Based Compensation	Stock Based Compensation As of December 31, 2021, the Company had four active stock-based employee compensation plans. These plans include three executive stock award plans, the Executive Incentive Plan (EIP), the Restricted Stock Award Plan (RSAP), the Strategic Deployment Incentive Plan (SDP); and the Employee Stock Purchase Plan (ESPP). The 2011 Stock Option Plan was approved by the shareholders on April 21, 2011 but the Company had not made any grants through December 31, 2021. These stock-based employee compensation plans were established to help retain and motivate key employees. All of the plans have been approved by the shareholders of 1st Source Corporation. The Executive Compensation and Human Resources Committee (the “Committee”) of the 1st Source Corporation Board of Directors has sole authority to select the employees, establish the awards to be issued, and approve the terms and conditions of each award under the stock-based compensation plans. Stock-based compensation to employees is recognized as compensation cost on the Consolidated Statements of Income based on their fair values on the measurement date, which, for 1st Source, is the date of grant. Stock-based compensation expense is recognized ratably over the requisite service period for all awards. The total fair value of share awards vested was $3.45 million during 2021, $2.67 million in 2020, and $3.35 million in 2019. The following table shows the combined summary of activity regarding active stock option and stock award plans. Non-Vested Stock Awards Outstanding Shares Available for Grant Number of Shares Weighted-Average Grant-Date Fair Value Balance, January 1, 2019 675,059 253,819 $ 28.59 Shares authorized - 2019 EIP 62,538 — — Granted (74,336) 74,336 31.44 Stock awards vested — (100,299) 28.35 Forfeited 1,241 (8,865) 30.28 Balance, December 31, 2019 664,502 218,991 29.60 Shares authorized - 2020 EIP 60,233 — — Granted (147,576) 147,576 37.41 Stock awards vested — (74,203) 28.95 Forfeited 49 (870) 31.82 Balance, December 31, 2020 577,208 291,494 33.71 Shares authorized - 2021 EIP 62,369 — — Granted (79,072) 79,072 36.22 Stock awards vested — (92,622) 32.53 Forfeited 250 (3,798) 32.13 Balance, December 31, 2021 560,755 274,146 $ 34.86 Stock Option Plans — Incentive stock option plans include the 2011 Stock Option Plan (the “2011 Plan”). Each award from the plan is evidenced by an award agreement that specifies the option price, the duration of the option, the number of shares to which the option pertains, and such other provisions as the Committee determines. The option price is equal to the fair market value of a share of 1st Source Corporation’s common stock on the date of grant. Options granted expire at such time as the Committee determines at the date of grant and in no event does the exercise period exceed a maximum of ten years. Upon merger, consolidation, or other corporate consolidation in which 1st Source Corporation is not the surviving corporation, as defined in the plans, all outstanding options immediately vest. There were zero stock options exercised during 2021, 2020 or 2019. All shares issued in connection with stock option exercises and non-vested stock awards are issued from available treasury stock. No stock-based compensation expense related to stock options was recognized in 2021, 2020 or 2019. The fair value of each option on the date of grant is estimated using the Black-Scholes option pricing model. Expected volatility is based on the historical volatility estimated over a period equal to the expected life of the options. In estimating the fair value of stock options under the Black-Scholes valuation model, separate groups of employees that have similar historical exercise behavior are considered separately. The expected life of the options granted is derived based on past experience and represents the period of time that options granted are expected to be outstanding. Stock Award Plans — Incentive stock award plans include the EIP, the SDP and the RSAP. The EIP is administered by the Committee. Awards under the EIP and SDP include “book value” shares and “market value” shares of common stock. These shares are awarded annually based on weighted performance criteria and generally vest over a period of five years. The EIP book value shares may only be sold to 1st Source and such sale is mandatory in the event of death, retirement, disability, or termination of employment. The RSAP is designed for key employees. Awards under the RSAP are made to employees recommended by the Chief Executive Officer and approved by the Committee. Shares granted under the RSAP vest over a period of up to ten years and vesting is based upon meeting certain various criteria, including continued employment with 1st Source. Stock-based compensation expense relating to the EIP, SDP and RSAP totaled $4.21 million in 2021, $3.29 million in 2020, and $2.76 million in 2019. The total income tax benefit recognized in the accompanying Consolidated Statements of Income related to stock-based compensation was $0.99 million in 2021, $0.77 million in 2020, and $0.65 million in 2019. Unrecognized stock-based compensation expense related to non-vested stock awards (EIP/SDP/RSAP) was $7.25 million at December 31, 2021. At such date, the weighted-average period over which this unrecognized expense was expected to be recognized was 3.17 years. The fair value of non-vested stock awards for the purposes of recognizing stock-based compensation expense is market price of the stock on the measurement date, which, for the Company’s purposes is the date of the award. Employee Stock Purchase Plan — The Company offers an ESPP for substantially all employees with at least two years of service on the effective date of an offering under the plan. Eligible employees may elect to purchase any dollar amount of stock, so long as such amount does not exceed 25% of their base rate of pay and the aggregate stock accrual rate for all offerings does not exceed $25,000 in any calendar year. The purchase price for shares offered is the lower of the closing market bid price for the offering date or the average market bid price for the five business days preceding the offering date. The purchase price and premium/(discount) to the actual market closing price on the offering date for the 2021, 2020, and 2019 offerings were $49.98 (-0.42%), $34.35 (1.78%), and $43.81 (0.14%), respectively. Payment for the stock is made through payroll deductions over the offering period, and employees may discontinue the deductions at any time and exercise the option or take the funds out of the program. The most recent offering began June 1, 2021 and runs through June 1, 2023, with $187,740 in stock value to be purchased at $49.98 per share.

Tax years that remain open and subject to audit include the federal 2018-2021 years and the Indiana 2018-2021 years. The Company does not anticipate a significant change in the amount of uncertain tax positions within the next 12 months.

Contingent Liabilities, Commitm

Contingent Liabilities, Commitments, and Financial Instruments with Off-Balance-Sheet Risk	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities, Commitments, and Financial Instruments with Off-Balance-Sheet Risk	Contingent Liabilities, Commitments, and Financial Instruments with Off-Balance-Sheet Risk Contingent Liabilities —1st Source and its subsidiaries are defendants in various legal proceedings arising in the normal course of business. In the opinion of management, based upon present information including the advice of legal counsel, the ultimate resolution of these proceedings will not have a material effect on the Company’s consolidated financial position or results of operations. 1st Source Bank sells residential mortgage loans to Fannie Mae as well as FHA-insured, USDA-insured and VA-guaranteed loans in Ginnie Mae mortgage-backed securities. Additionally, the Bank has sold loans on a service released basis to various other financial institutions in the past. The agreements under which the Bank sells these mortgage loans contain various representations and warranties regarding the acceptability of loans for purchase. On occasion, the Bank may be required to indemnify the loan purchaser for credit losses on loans that were later deemed ineligible for purchase or may be required to repurchase a loan. Both circumstances are collectively referred to as “repurchases.” The Company’s liability for repurchases, included in Accrued Expenses and Other Liabilities on the Consolidated Statements of Financial Condition, was $0.22 million and $0.33 million as of December 31, 2021 and 2020, respectively. The mortgage repurchase liability represents the Company’s best estimate of the loss that it may incur. The estimate is based on specific loan repurchase requests and a historical loss ratio with respect to origination dollar volume. Because the level of mortgage loan repurchase losses are dependent on economic factors, investor demand strategies and other external conditions that may change over the life of the underlying loans, the level of liability for mortgage loan repurchase losses is difficult to estimate and requires considerable management judgment. Lease Commitments — The Company and its subsidiaries are obligated under operating leases for certain office premises and equipment. The following table shows operating lease right of use assets and operating lease liabilities as of December 31. (Dollars in thousands) Statement of Financial Condition classification 2021 2020 Operating lease right of use assets Accrued income and other assets $ 22,071 $ 23,825 Operating lease liabilities Accrued expenses and other liabilities $ 21,364 $ 23,688 The following table shows the components of operating leases expense for the year ended December 31.

The Company commenced an operating lease with the buyer of the building to lease a portion of it for office space resulting in a new right of use asset and operating lease liability. There were no new significant leases that had not yet commenced as of December 31, 2021. Financial Instruments with Off-Balance-Sheet Risk — To meet the financing needs of our clients, 1st Source and its subsidiaries are parties to financial instruments with off-balance-sheet risk in the normal course of business. These off-balance-sheet financial instruments include commitments to originate and sell loans and standby letters of credit. The instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. Financial instruments, whose contract amounts represent credit risk as of December 31, were as follows: (Dollars in thousands) 2021 2020 Amounts of commitments: Loan commitments to extend credit $ 1,148,984 $ 1,140,892 Standby letters of credit $ 24,657 $ 24,884 Commercial and similar letters of credit $ 8,531 $ 7,095 The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for loan commitments and standby letters of credit is represented by the dollar amount of those instruments. The Company uses the same credit policies and collateral requirements in making commitments and conditional obligations as it does for on-balance-sheet instruments. Loan commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company grants mortgage loan commitments to borrowers subject to normal loan underwriting standards. The interest rate risk associated with these loan commitments is managed by entering into contracts for future deliveries of loans. Standby letters of credit are conditional commitments issued to guarantee the performance of a client to a third party. The credit risk involved in and collateral obtained when issuing standby letters of credit are essentially the same as those involved in extending loan commitments to clients. Standby letters of credit generally have terms ranging from two months to one year. Commercial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and the third party. Commercial letters of credit generally have terms ranging from two months to six months.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments Commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans are considered derivative instruments. See Note 18 for further information. The Company has certain interest rate derivative positions that are not designated as hedging instruments. Derivative assets and liabilities are recorded at fair value on the Consolidated Statements of Financial Condition and do not take into account the effects of master netting agreements. Master netting agreements allow the Company to settle all derivative contracts held with a single counterparty on a net basis, and to offset net derivative positions with related collateral, where applicable. These derivative positions relate to transactions in which the Company enters into an interest rate swap with a client while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each transaction, the Company agrees to pay interest to the client on a notional amount at a variable interest rate and receive interest from the client on the same notional amount at a fixed interest rate. At the same time, the Company agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows the client to effectively convert a variable rate loan to a fixed rate. Because the terms of the swaps with the customers and the other financial institution offset each other, with the only difference being counterparty credit risk, changes in the fair value of the underlying derivative contracts are not materially different and do not significantly impact the Company’s results of operations. The following table shows the amounts of non-hedging derivative financial instruments at December 31, 2021 and 2020. Asset derivatives Liability derivatives (Dollars in thousands) Notional or contractual amount Statement of Financial Condition classification Fair value Statement of Financial Condition classification Fair value Interest rate swap contracts $ 1,064,721 Other assets $ 20,735 Other liabilities $ 21,172 Loan commitments 15,086 Mortgages held for sale 452 N/A — Forward contracts - mortgage loan 22,000 N/A — Mortgages held for sale 11 Total - December 31, 2021 $ 1,101,807 $ 21,187 $ 21,183 Interest rate swap contracts $ 1,155,252 Other assets $ 46,654 Other liabilities $ 47,681 Loan commitments 32,588 Mortgages held for sale 1,487 N/A — Forward contracts - mortgage loan 38,310 N/A — Mortgages held for sale 290 Total - December 31, 2020 $ 1,226,150 $ 48,141 $ 47,971 The following table shows the amounts included on the Consolidated Statements of Income for non-hedging derivative financial instruments at December 31, 2021, 2020 and 2019.

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Matters	Regulatory Matters The Company is subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet minimum capital requirements can result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. Capital amounts and classification are subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios of total capital, Tier 1 capital, and common equity Tier 1 capital to risk-weighted assets and of Tier 1 capital to average assets. The Company believes that it meets all capital adequacy requirements to which it is subject. The most recent notification from the Federal bank regulators categorized 1st Source Bank, the largest of its subsidiaries, as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized” the Bank must maintain minimum total risk-based, Tier 1 risk-based, common equity Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since that notification that the Company believes will have changed the institution’s category. As discussed in Note 12, the capital securities held by the Capital Trusts qualify as Tier 1 capital under Federal Reserve Board guidelines. The following table shows the actual and required capital amounts and ratios for 1st Source Corporation and 1st Source Bank as of December 31, 2021 and 2020.

Due to the Company’s mortgage activities, 1st Source Bank is required to maintain minimum net worth capital requirements established by various governmental agencies. 1st Source Bank’s net worth requirements are governed by the Department of Housing and Urban Development and GNMA. As of December 31, 2021, 1st Source Bank met its minimum net worth capital requirements.

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2021
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company determines the fair values of its financial instruments based on the fair value hierarchy, which requires an entity to maximize the use of quoted prices and observable inputs and to minimize the use of unobservable inputs when measuring fair value. The Company elected fair value accounting for mortgages held for sale and for its best-efforts forward sales commitments. The Company economically hedges its mortgages held for sale at the time the interest rate locks are issued to the customers. The Company believes the election for mortgages held for sale will reduce certain timing differences and better match changes in the value of these assets with changes in the value of the derivatives or best-efforts forward sales commitments. At December 31, 2021 and 2020, all mortgages held for sale are carried at fair value. The following table shows the differences between fair value carrying amount of mortgages held for sale measured at fair value and the aggregate unpaid principal amount the Company is contractually entitled to receive at maturity on December 31, 2021 and 2020. (Dollars in thousands) Fair value carrying amount Aggregate unpaid principal Excess of fair value carrying amount over (under) unpaid principal December 31, 2021 Mortgages held for sale reported at fair value: Total Loans $ 13,284 $ 12,456 $ 828 (1) December 31, 2020 Mortgages held for sale reported at fair value: Total Loans $ 12,885 $ 11,045 $ 1,840 (1) (1) The excess of fair value carrying amount over (under) unpaid principal is included in mortgage banking income and includes changes in fair value at and subsequent to funding and gains and losses on the related loan commitment prior to funding. Financial Instruments on Recurring Basis: The following is a description of the valuation methodologies used for financial instruments measured at fair value on a recurring basis: Investment securities available-for-sale are valued primarily by a third-party pricing agent. Prices supplied by the independent pricing agent, as well as their pricing methodologies and assumptions, are reviewed by the Company for reasonableness and to ensure such prices are aligned with market levels. In general, the Company’s investment securities do not possess a complex structure that could introduce greater valuation risk. The portfolio mainly consists of traditional investments including U.S. Treasury and Federal agencies securities, Federal agency mortgage pass-through securities, and general obligation and revenue municipal bonds. Pricing for such instruments is fairly generic and is easily obtained. On a quarterly basis, prices supplied by the pricing agent are validated by comparison to prices obtained from other third party sources for a material portion of the portfolio. The valuation policy and procedures for Level 3 fair value measurements of available-for-sale debt securities are decided through collaboration between management of the Corporate Accounting and Funds Management departments. The changes in fair value measurement for Level 3 securities are analyzed on a periodic basis under a collaborative framework with the aforementioned departments. The methodology and variables used for input are derived from the combination of observable and unobservable inputs. The unobservable inputs are determined through internal assumptions that may vary from period to period due to external factors, such as market movement and credit rating adjustments. Both the market and income valuation approaches are implemented using the following types of inputs: • U.S. treasuries are priced using the market approach and utilizing live data feeds from active market exchanges for identical securities. • Government-sponsored agency debt securities and corporate bonds are primarily priced using available market information through processes such as benchmark curves, market valuations of like securities, sector groupings and matrix pricing. • Other government-sponsored agency securities, mortgage-backed securities and some of the actively traded REMICs and CMOs, are primarily priced using available market information including benchmark yields, prepayment speeds, spreads and volatility of similar securities. • State and political subdivisions are largely grouped by characteristics, i.e., geographical data and source of revenue in trade dissemination systems. Since some securities are not traded daily and due to other grouping limitations, active market quotes are often obtained using benchmarking for like securities. Local direct placement municipal securities, with very little market activity, are priced using an appropriate market yield curve which incorporates a credit spread assumption. Mortgages held for sale and the related loan commitments and forward contracts (hedges) are valued by a third party pricing agent. Prices supplied by the independent pricing agent, as well as their pricing methodologies, are reviewed by the Company for reasonableness and to ensure such prices are aligned with market values. On a quarterly basis, prices supplied by the pricing agent are validated by comparison to the prices obtained from other third party sources. Interest rate swap positions, both assets and liabilities, are valued by a third-party pricing agent using an income approach and utilizing models that use as their basis readily observable market parameters. This valuation process considers various factors including interest rate yield curves, time value and volatility factors. Validation of third-party agent valuations is accomplished by comparing those values to the Company’s swap counterparty valuations. Management believes an adjustment is required to “mid-market” valuations for derivatives tied to its performing loan portfolio to recognize the imprecision and related exposure inherent in the process of estimating expected credit losses as well as velocity of deterioration evident with systemic risks embedded in these portfolios. Any change in the mid-market derivative valuation adjustment will be recognized immediately through the Consolidated Statements of Income. The following table shows the balance of assets and liabilities measured at fair value on a recurring basis.

The following table shows the valuation methodology and unobservable inputs for Level 3 assets and liabilities measured at fair value on a recurring basis. (Dollars in thousands) Fair value Valuation Methodology Unobservable Inputs Range of Inputs Weighted Average December 31, 2021 Debt securities available-for-sale Direct placement municipal securities $ 1,849 Discounted cash flows Credit spread assumption 0.04% - 2.31% 1.58 % December 31, 2020 Debt securities available-for-sale Direct placement municipal securities $ 2,152 Discounted cash flows Credit spread assumption 0.04% - 2.30% 1.55 % Financial Instruments on Non-recurring Basis: The Company may be required, from time to time, to measure certain other financial assets at fair value on a non-recurring basis in accordance with GAAP. These adjustments to fair value usually result from application of lower of cost or market accounting or impairment charges of individual assets. The Credit Policy Committee (CPC), a management committee, is responsible for overseeing the valuation processes and procedures for Level 3 measurements of impaired loans, other real estate and repossessions. The CPC reviews these assets on a quarterly basis to determine the accuracy of the observable inputs, generally third-party appraisals, auction values, values derived from trade publications and data submitted by the borrower, and the appropriateness of the unobservable inputs, generally discounts due to current market conditions and collection issues. The CPC establishes discounts based on asset type and valuation source; deviations from the standard are documented. The discounts are reviewed periodically, annually at a minimum, to determine they remain appropriate. Consideration is given to current trends in market values for the asset categories and gain and losses on sales of similar assets. The Loan and Funds Management Committee of the Board of Directors is responsible for overseeing the CPC. Discounts vary depending on the nature of the assets and the source of value. Aircraft are generally valued using quarterly trade publications adjusted for engine time, condition, maintenance programs, discounted by 10%. Likewise, autos are valued using current auction values, discounted by 10%; medium and heavy duty trucks are valued using trade publications and auction values, discounted by 15%. Construction equipment is generally valued using trade publications and auction values, discounted by 20%. Real estate is valued based on appraisals or evaluations, discounted by 20% at a minimum with higher discounts for property in poor condition or property with characteristics which may make it more difficult to market. Commercial loans subject to borrowing base certificates are generally discounted by 20% for receivables and 40% - 75% for inventory with higher discounts when monthly borrowing base certificates are not required or received. Collateral-dependent impaired loans and related write-downs are based on the fair value of the underlying collateral if repayment is expected solely from the collateral. Collateral values are reviewed quarterly and estimated using customized discounting criteria, appraisals and dealer and trade magazine quotes which are used in a market valuation approach. In accordance with fair value measurements, only impaired loans for which an allowance for loan loss has been established based on the fair value of collateral require classification in the fair value hierarchy. As a result, only a portion of the Company’s impaired loans are classified in the fair value hierarchy. The Company has established MSRs valuation policies and procedures based on industry standards and to ensure valuation methodologies are consistent and verifiable. MSRs and related adjustments to fair value result from application of lower of cost or fair value accounting. For purposes of impairment, MSRs are stratified based on the predominant risk characteristics of the underlying servicing, principally by loan type. The fair value of each tranche of the servicing portfolio is estimated by calculating the present value of estimated future net servicing cash flows, taking into consideration actual and expected mortgage loan prepayment rates, discount rates, servicing costs, and other economic factors. Prepayment rates and discount rates are derived through a third-party pricing agent. Changes in the most significant inputs, including prepayment rates and discount rates, are compared to the changes in the fair value measurements and appropriate resolution is made. A fair value analysis is also obtained from an independent third-party agent and compared to the internal valuation for reasonableness. MSRs do not trade in an active, open market with readily observable prices and though sales of MSRs do occur, precise terms and conditions typically are not readily available and the characteristics of the Company’s servicing portfolio may differ from those of any servicing portfolios that do trade. Other real estate is based on the fair value of the underlying collateral less expected selling costs. Collateral values are estimated primarily using appraisals and reflect a market value approach. Fair values are reviewed quarterly and new appraisals are obtained annually. Repossessions are similarly valued. For assets measured at fair value on a nonrecurring basis the following represents impairment charges (recoveries) recognized on these assets during the year ended December 31, 2021 and 2020, respectively: collateral-dependent impaired loans - $2.76 million and $7.73 million; MSRs - $(0.81) million and $0.81 million; repossessions - $0.27 million and $1.07 million, and other real estate - $0.06 million and $0.00 million.

These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. These estimates are subjective in nature and require considerable judgment to interpret market data. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange, nor are they intended to represent the fair value of the Company as a whole. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. The fair value estimates presented herein are based on pertinent information available to management as of the respective balance sheet date. Although the Company is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein.

Accounting Policies (Policies)

Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation — The financial statements consolidate 1st Source, its subsidiaries (principally the Bank) and any variable interest entities (“VIEs”) for which the Company has concluded it has significant involvement in and the ability to direct the activities that impact the entity’s economic performance. All significant intercompany balances and transactions have been eliminated. For purposes of the parent company only financial information presented in Note 22, investments in subsidiaries are carried at equity in the underlying net assets.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements — Financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) require the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
Business Combinations	Business Combinations — Business combinations are accounted for under the purchase method of accounting. Under the purchase method, assets and liabilities of the business acquired are recorded at their estimated fair values as of the date of acquisition with any excess of the cost of the acquisition over the fair value of the net tangible and intangible assets acquired recorded as goodwill. Results of operations of the acquired business are included in the income statement from the date of acquisition.
Cash Flows	Cash Flows — For purposes of the consolidated and parent company only statements of cash flows, the Company considers cash and due from banks, federal funds sold and interest bearing deposits with other banks with original maturities of three months or less as cash and cash equivalents.
Securities	Securities — Securities that the Company has the ability and positive intent to hold to maturity are classified as investment securities held-to-maturity. Held-to-maturity investment securities, when present, are carried at amortized cost. As of December 31, 2021 and 2020, the Company held no securities classified as held-to-maturity. Securities that may be sold in response to, or in anticipation of, changes in interest rates and resulting prepayment risk, or for other factors, are classified as available-for-sale and are carried at fair value. Unrealized gains and losses on debt securities are reported, net of applicable taxes, as a separate component of accumulated other comprehensive income (loss) in shareholders’ equity. Unrealized gains and losses on equity securities are reflected, net of applicable taxes, in earnings. For available-for-sale securities in an unrealized loss position, the Company 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 these criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value in Other Income on the Consolidated Statements of Income. For debt securities that do not meet the aforementioned criteria, the Company 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, nature of the security, the underlying collateral, and the financial condition of the issuer, among other factors. If this assessment indicates 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 the cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for available-for-sale securities 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 available-for-sale securities losses is recognized in other comprehensive income. Changes in the allowance for available-for-sale securities are recorded as a component of credit loss expense. Losses are charged against the allowance for available-for-sale securities losses when management believes the uncollectibility of an available-for-sale security is confirmed or when either criteria regarding intent or requirement to sell is met. Debt and equity securities that are purchased and held principally for the purpose of selling them in the near term are classified as trading account securities and are carried at fair value with unrealized gains and losses reported in earnings. Realized gains and losses on the sales of all securities are reported in earnings and computed using the specific identification cost basis.
Loans and Leases	Loans and Leases — Loans are stated at the principal amount outstanding, net of unamortized deferred loan origination fees and costs and net of unearned income. Interest income is accrued as earned based on unpaid principal balances. Origination fees and direct loan and lease origination costs are deferred, and the net amount amortized to interest income over the estimated life of the related loan or lease. Loan commitment fees are deferred and amortized into other income over the commitment period. Direct financing leases are carried at the aggregate of lease payments plus estimated residual value of the leased property, net of unamortized deferred lease origination fees and costs and unearned income. Interest income on direct financing leases is recognized over the term of the lease to achieve a constant periodic rate of return on the outstanding investment. Effective January 1, 2019, as part of the new leasing standard, only those costs incurred as a direct result of closing a lease transaction are capitalized. All existing deferrals will continue to be amortized over the estimated life of the lease while all new initial direct costs are expensed immediately. Accrued interest is included in Accrued Income and Other Assets on the Consolidated Statements of Financial Condition. The accrual of interest on loans and leases is discontinued when a loan or lease becomes contractually delinquent for 90 days, or when an individual analysis of a borrower’s credit worthiness indicates a credit should be placed on nonperforming status, except for residential mortgage loans and consumer loans that are well secured and in the process of collection. Residential mortgage loans are placed on nonaccrual at the time the loan is placed in foreclosure. When interest accruals are discontinued, interest credited to income in the current year is reversed and interest accrued in the prior year is charged to the allowance for loan and lease losses. However, in some cases, the Company may elect to continue the accrual of interest when the net realizable value of collateral is sufficient to cover the principal and accrued interest. When a loan or lease is classified as nonaccrual and the future collectability of the recorded loan or lease balance is doubtful, collections on interest and principal are applied as a reduction to principal outstanding. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured, which is typically evidenced by a sustained repayment performance of at least six months. Loans and leases that have been modified and economic concessions have been granted to borrowers who have experienced financial difficulties are considered a troubled debt restructuring (TDR). These concessions typically result from the Company’s loss mitigation activities and may include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. Certain TDRs are classified as nonperforming at the time of restructuring and typically are returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period of at least six months. When the Company modifies loans and leases in a TDR, it evaluates any possible impairment based on the present value of expected future cash flows, discounted at the contractual interest rate of the original loan or lease agreement, or uses the current fair value of the collateral, less selling costs for collateral dependent loans. If the Company determines that the value of the modified loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through an allowance for loan and lease losses estimate or a charge-off to the allowance for loan and lease losses. In periods subsequent to modification, the Company evaluates all TDRs, including those that have payment defaults, for possible impairment and recognizes impairment through the allowance for loan and lease losses. On March 27, 2020, the President of the United States signed the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), which provides entities with optional temporary relief from certain accounting and financial reporting requirements under U.S. GAAP. Section 4013 of the CARES Act allows financial institutions to suspend application of certain TDR accounting guidance for loan and lease modifications related to the COVID-19 pandemic made between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the end of the COVID-19 national emergency, provided certain criteria are met. Section 4013 of the CARES Act was amended on December 27, 2020 to extend this relief until January 1, 2022. The relief can be applied to loan and lease modifications for borrowers that were not more than 30 days past due as of December 31, 2019 and to loan and lease modifications that defer or delay the payment of principal or interest, or change the interest rate on the loan. The Company chose to apply this relief to eligible loan and lease modifications. At December 31, 2021 and December 31, 2020, loan and lease modification balances related to the COVID-19 pandemic were $0 million and $129 million, respectively.
Mortgage Banking Activities	Mortgage Banking Activities — Loans held for sale are composed of performing one-to-four family residential mortgage loans originated for resale. Mortgage loans originated with the intent to sell are carried at fair value. The Company recognizes the rights to service mortgage loans for others as separate assets, whether the servicing rights are acquired through a separate purchase or through the sale of originated loans with servicing rights retained. The Company allocates a portion of the total proceeds of a mortgage loan to servicing rights based on the relative fair value. These assets are amortized as reductions of mortgage servicing fee income over the estimated servicing period in proportion to the estimated servicing income to be received. The balance of MSRs is located in Accrued Income and Other Assets on the Consolidated Statements of Financial Condition and the gains and losses on the sale of MSRs are recognized in Noninterest Income on the Consolidated Statements of Income in the period in which such rights are sold. MSRs are evaluated for impairment at each reporting date. For purposes of impairment measurement, MSRs are stratified based on the predominant risk characteristics of the underlying servicing, principally by loan type. If temporary impairment exists within a tranche, a valuation allowance is established through a charge to income equal to the amount by which the carrying value exceeds the fair value. If it is later determined all or a portion of the temporary impairment no longer exists for a particular tranche, the valuation allowance is reduced through a recovery of income. MSRs are also reviewed for permanent impairment. Permanent impairment exists when recoverability of a recorded valuation allowance is determined to be remote considering historical and projected interest rates, prepayments, and loan pay-off activity. When this situation occurs, the unrecoverable portion of the valuation allowance is applied as a direct write-down to the carrying value of the MSRs. Unlike a valuation allowance, a direct write-down permanently reduces the carrying value of the MSRs and the valuation allowance, precluding subsequent recoveries. As part of mortgage banking operations, the Company enters into commitments to originate loans whereby the interest rate on these loans is determined prior to funding (“rate lock commitments”). Similar to loans held for sale, the fair value of rate lock commitments is subject to change primarily due to changes in interest rates. Under the Company’s risk management policy, these fair values are hedged primarily by selling forward contracts on agency securities at the time the interest rate locks are issued to the customers. The rate lock commitments on mortgage loans intended to be sold and the related hedging instruments are recorded at fair value with changes in fair value recorded in current earnings.
Allowance for credit losses	Allowance for Credit Losses: Loans and leases — Accrued interest on loans and leases is excluded from the calculation of the allowance for credit losses due to the Company’s charge-off policy to reverse accrued interest on nonperforming loans against interest income in a timely manner. Expected credit losses on net investments in leases, including any unguaranteed residual asset, are included in the allowance for loan and lease losses. Allowance for Loan and Lease Losses — Effective January 1, 2020, the allowance for credit losses is established for current expected credit losses on the Company’s loan and lease portfolio. Prior to January 1, 2020, the allowance was established based on an incurred loss model. It is the Company’s policy to maintain the allowance at a level believed to be adequate to absorb estimated credit losses within its portfolio of loans and leases. The determination of the allowance requires significant judgment to estimate credit losses measured on a collective pool basis when similar risk characteristics exist, and for loans evaluated individually. In determining the allowance, the Company estimates expected future losses for the loan’s entire contractual term adjusted for expected payments when appropriate. The allowance estimate considers relevant available information, from internal and external sources relating to the historical loss experience, current conditions, and reasonable and supportable forecasts for the Company’s outstanding loan and lease balances. The allowance is an estimation that reflects management’s evaluation of expected losses related to the Company’s financial assets measured at amortized cost. To ensure that the allowance is maintained at an adequate level, a detailed analysis is performed on a quarterly basis and an appropriate provision is made to adjust the allowance. The Company categorizes its loan portfolios into nine segments based on similar risk characteristics. Loans within each segment are collectively evaluated using either: 1) a cohort cumulative loss rate methodology (“cohort”) or, 2) the probability of default (“PD”)/loss given default (“LGD”) methodology (PD/LGD). The cohort methodology is applied to ungraded portfolios, portfolios where receipt of financial statements is generally less timely, and portfolios where there are numerous small dollar accounts that are credit scored. Loans are broken out by internal risk rating (loan grade) bands: 1-6 and 7-12 (special attention). For ungraded portfolios, there is only one pool. The cohort methodology has a steady state assumption; qualitative adjustments capture any differences that may exist between the current and historical conditions. The PD/LGD methodology is applied to graded portfolios due to the quantitative nature of the Company’s risk rating system and is consistent with the Company’s definition of risk, downgrading a credit where and when appropriate and recognizing losses in a timely manner. Loans are broken out by risk rating (loan grade) bands: 1-3, 4-6, 7-8, and 9-12. The amortized cost loan balances (rather than counts) are used for determining the transition and default probabilities. The Company uses risk rating bands as the active state to track the movement of loans through the transition matrix. The transition frequency is quarterly. Default is defined as the point at which a loan is placed on non-accrual status. In addition, a charge-off is assumed to be a default (i.e. a loan goes from accruing to charge-off, without ever being on non-accrual status). The PD is the cumulative probability of default estimated by use of a transition matrix (based on a Markov transition matrix methodology) which captures the migration of a loan from one risk rating band to another. The LGD is the ratio of loss relative to the exposure (amortized cost) at default. The current expected credit loss methodology has a factor for reasonable and supportable forecasts. Generally, reasonable and supportable forecasts are for two years or less and have a reversion period of a similar duration, reverting expected credit losses to a level that is consistent with our historical loss experience. Forecast adjustments are added via basis points for the cohort methodology. For the PD/LGD methodology, adjustments to the probability of default factor are applied through forecast adjustments to the PD factor used as the baseline transition matrix runout, thus impacting the historical loss ratio. The Company developed its reasonable and supportable forecasts using relevant data including, but not limited to, growth in gross domestic product, unemployment rates, housing market trends, commodity prices, inflation, and other factors associated with credit losses on the financial statements. For both the cohort and the PD/LGD methodologies, the Company uses qualitative adjustments to capture differences that may exist between the current and historical conditions. Qualitative factors include but are not limited to current market risk assessment by industry, recent loss experience in particular segments of the portfolios, movement in equipment values collateralizing specialized industry portfolios, concentrations of credit risk, delinquencies, trends in volume, experience and depth of relationship managers and division management, and the effects of changes in lending policies and practices, including changes in quality of the loan and lease origination, servicing and risk management process. Loans which exhibit different risk characteristics than the pool are evaluated individually for impairment. Loans evaluated individually are not included in the collective evaluation. These loans can be identified from a variety of sources including delinquency, non-accrual status and troubled debt restructurings (TDRs). The scope may include accruing loans that exhibit risk characteristics which differ from their pool or non-performing loans with risk characteristics not similar to other special attention loans in their pool. Individual reserves are determined based on an analysis of the loan’s expected future cash flows, the loan’s observable market value, or the fair value of the collateral less costs to sell. When foreclosure is probable, impairment is determined based on the collateral’s fair value less costs to sell. As a practical expedient, fair value less costs to sell may be used when developing the estimate of credit losses. Similarly, for a going concern analysis, a discounted cash method may be used. Liability for Credit Losses on Unfunded Loan Commitments — The liability for credit losses on commitments to originate loans and standby letters of credit is included in Accrued Expenses and Other Liabilities on the Consolidated Statements of Financial Condition. Expected credit losses are estimated over the contractual period in which the Company is exposed to credit risk via a contractual obligation unless the obligation is unconditionally cancellable by the Company. The liability for credit losses on unfunded loan commitments is adjusted as a provision for credit losses in Other Noninterest Expense on the Consolidated Statements of Income. 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 useful life. Because business processes and credit risks associated with unfunded credit commitments are essentially the same as for loans, the Company utilizes similar processes to estimate its liability for unfunded credit commitments.
Equipment Owned Under Operating Leases	Equipment Owned Under Operating Leases — As a lessor, the Company finances various types of construction equipment, medium and heavy duty trucks, automobiles and other equipment under leases classified as operating leases. The equipment underlying the operating leases is reported at cost, net of accumulated depreciation, on the Consolidated Statements of Financial Condition. These operating lease arrangements require the lessee to make a fixed monthly rental payment over a specified lease term generally ranging from three years to seven years. Revenue consists of the contractual lease payments and is recognized on a straight-line basis over the lease term and reported in Noninterest Income on the Consolidated Statements of Income. Leased assets are depreciated on a straight-line method over the lease term to the estimate of the equipment’s fair market value at lease termination, also referred to as “residual” value. The depreciation of these operating lease assets is reported in Noninterest Expense on the Consolidated Statements of Income. For automobile leases, fair value is based upon published industry market guides. For other equipment leases, fair value may be based upon observable market prices, third-party valuations, or prices received on sales of similar assets at the end of the lease term. These residual values are reviewed annually to ensure the recorded amount does not exceed the fair market value at the lease termination. At the end of the lease, the operating lease asset is either purchased by the lessee or returned to the Company. The Company is responsible for the payment of personal property taxes which is reported in Other Expense on the Consolidated Statements of Income. The lessee is responsible for reimbursing the Company for personal property taxes which is reported in Other Income on the Consolidated Statements of Income. The Company excludes sales taxes and other similar taxes from being reported as lease revenue with an associated expense.
Lease Commitments	Lease Commitments — The Company leases certain banking center locations, office space, land and billboards. In determining whether a contract contains a lease, the Company examines the contract to ensure an asset was specifically identified and that the Company has control of use over the asset. To determine whether a lease is classified as operating or finance, the Company performs an economic life test on all building leases with greater than a twenty years term. Further, the Company performs a fair value test to identify any leases that have a present value of future lease payments over the lease term that is greater than 90% of the fair value of the building. The Company only capitalizes leases with an initial lease liability of $2,000 or greater. At lease inception, the Company determines the lease term by adding together the minimum lease term and all optional renewal periods that it is reasonably certain to renew. The Company determines this on each lease by considering all relevant contract-based, asset-based, market-based, and entity-based economic factors. Generally, the exercise of lease renewal options is at the Company’s sole discretion. The lease term is used to determine whether a lease is operating or finance and is used to calculate straight-line rent expense. Additionally, the depreciable life of leasehold improvements is limited by the expected lease term. Operating lease rentals are expensed on a straight-line basis over the life of the lease beginning on the date the Company takes possession of the property. Rent expense and variable lease costs are included in Net Occupancy Expense on the Consolidated Statements of Income. Included in variable lease costs are leases with rent escalations based on recent financial indices, such as the Consumer Price Index, where the Company initially measures lease payments using the index on the commencement date and records future changes in rent payments resulting from changes in the index to variable costs in the period the changes occur. Certain leases require the Company to pay common area maintenance, real estate taxes, insurance and other operating expenses associated with the leases premises. These expenses are classified in Net Occupancy Expense on the Consolidated Statements of Income, consistent with similar costs for owned locations. There are no residual value guarantees, restrictions or covenants imposed by leases. The Company accounts for lease and nonlease components together as a single lease component by class of underlying asset. Operating lease obligations with an initial term longer than 12 months are recorded with a right of use asset and a lease liability on the Consolidated Statements of Financial Condition. The discount rate used in determining the lease liability and related right of use asset is based upon what would be obtained by the Company for similar loans as an incremental rate as of the date of origination or renewal.
Other Real Estate	Other Real Estate — Other real estate acquired through partial or total satisfaction of nonperforming loans is included in Other Assets on the Consolidated Statements of Financial Condition and recorded at fair value less anticipated selling costs based upon the property’s appraised value at the date of transfer, with any difference between the fair value of the property less cost to sell, and the carrying value of the loan charged to the allowance for loan and lease losses or other income, if a positive adjustment. Subsequent fair value write-downs or write-ups, to the extent of previous write-downs, property maintenance costs, and gains or losses recognized upon the sale of other real estate are recognized in Noninterest Expense on the Consolidated Statements of Income. Gains or losses resulting from the sale of other real estate are recognized on the date of sale. As of December 31, 2021 and 2020, other real estate had carrying values of $0.00 million and $0.36 million, respectively, and is included in Other Assets on the Consolidated Statements of Financial Condition.
Repossessed Assets	Repossessed Assets — Repossessed assets may include fixtures and equipment, inventory and receivables, aircraft, construction equipment, and vehicles acquired from business banking and specialty finance activities. Repossessed assets are included in Other Assets on the Consolidated Statements of Financial Condition at fair value of the equipment or vehicle less estimated selling costs. At the time of repossession, the recorded amount of the loan or lease is written down to the fair value of the equipment or vehicle by a charge to the allowance for loan and lease losses or other income, if a positive adjustment. Subsequent fair value write-downs or write-ups, to the extent of previous write-downs, equipment maintenance costs, and gains or losses recognized upon the sale of repossessions are recognized in Noninterest Expense on the Consolidated Statements of Income. Gains or losses resulting from the sale of repossessed assets are recognized on the date of sale. Repossessed assets totaled $0.86 million and $1.98 million, as of December 31, 2021 and 2020, respectively, and are included in Other Assets on the Consolidated Statements of Financial Condition.
Premises and Equipment	Premises and Equipment — Premises and equipment are stated at cost, less accumulated depreciation and amortization. The provision for depreciation is computed by the straight-line method, primarily with useful lives ranging from three years to 31.5 years. Maintenance and repairs are charged to expense as incurred, while improvements, which extend the useful life, are capitalized and depreciated over the estimated remaining life.
Goodwill and Intangibles	Goodwill and Intangibles — Goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets acquired. Other intangible assets represent purchased assets that also lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Goodwill is reviewed for impairment at least annually or on an interim basis if an event occurs or circumstances change that would more likely than not reduce the carrying amount. Goodwill is allocated into two reporting units. Fair value for each reporting unit is estimated using stock price multiples or earnings before interest, tax, depreciation and amortization (EBITDA) multiples. Intangible assets that have finite lives are amortized over their estimated useful lives and are subject to impairment testing. All of the Company’s other intangible assets have finite lives and are amortized on a straight-line basis over varying periods not exceeding twenty-five years. The Company has historically evaluated goodwill for impairment during the fourth quarter of each year, with financial data as of September 30. During the first quarter of 2020, management determined that the deterioration in general economic conditions as a result of the COVID-19 pandemic and responses thereto represented a triggering event prompting an evaluation of goodwill impairment. The Company performed impairment analyses in each quarter of 2020. In 2021, management determined conditions no longer represented a triggering event requiring quarterly analyses and returned to its historical practice of evaluating goodwill during the fourth quarter of the year. Based on the analyses performed each quarter of 2020 and the fourth quarter of 2021, the Company determined that goodwill was not impaired.
Partnership Investments	Partnership Investments — The Company accounts for its investments in partnerships for which it owns less than fifty percent and has the ability to exercise significant influence over the partnership on the equity method. The Company accounts for its investments in partnerships for which it does not have the ability to exercise significant influence at fair value less impairment, if any or cost less any impairment if the fair value is not readily determinable. The Company has elected to use the practical expedient to estimate fair value of an investment in an investment company using the net asset value of its partnership interest. The Company uses the hypothetical liquidation book value (HLBV) method for equity investments when the liquidation rights and priorities as defined by an equity investment agreement differ from what is reflected by the underlying percentage ownership interests. The HLBV method is commonly applied to equity investments in the renewable energy industry, where the economic benefits corresponding to an equity investment may vary at different points in time and/or are not directly linked to an investor’s ownership percentage. A calculation is prepared at each balance sheet date to determine the amount that the Company would receive if an equity investment entity were to liquidate all of its assets (as valued in accordance with GAAP) and distribute that cash to the investors based on the contractually defined liquidation priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, after adjusting for capital contributions and distributions, is 1st Source’s share of the earnings or losses from the equity investment for the period. Investments in partnerships are included in Other Assets on the Consolidated Statements of Financial Condition. The balances as of December 31, 2021 and 2020 were $95.05 million and $76.35 million, respectively.
Short-Term Borrowings	Short-Term Borrowings — Short-term borrowings consist of Federal funds purchased, securities sold under agreements to repurchase, commercial paper, Federal Home Loan Bank notes, and borrowings from non-affiliated banks. Federal funds purchased, securities sold under agreements to repurchase, and other short-term borrowings mature within one day to 365 days of the transaction date. Commercial paper matures within seven days to 270 days. Other short-term borrowings on the Consolidated Statements of Financial Condition include the Company’s liability related to mortgage loans available for repurchase under GNMA optional repurchase programs. Securities purchased under agreements to resell and securities sold under agreements to repurchase are treated as collateralized financing transactions and are recorded at the amounts at which the securities were acquired or sold plus accrued interest. The fair value of collateral either received from or provided to a third-party is continually monitored and additional collateral obtained or requested to be returned to the Company as deemed appropriate.
Revenue Recognition	Revenue Recognition — The Company recognizes revenues as they are earned based on contractual terms, as transactions occur, or as services are provided and collectability is reasonably assured. The Company’s principal source of revenue is interest income from loans and leases and investment securities. The Company also earns noninterest income from various banking and financial services offered primarily through 1st Source Bank and its subsidiaries. Interest Income — The largest source of revenue for the Company is interest income which is primarily recognized on an accrual basis according to nondiscretionary formulas in written contracts, such as loan and lease agreements or investment securities contracts. Noninterest Income — The Company earns noninterest income through a variety of financial and transaction services provided to corporate and consumer clients such as trust and wealth advisory, deposit account, debit card, mortgage banking, insurance, and equipment rental services. Revenue is recorded for noninterest income based on the contractual terms for the service or transaction performed. In certain circumstances, noninterest income is reported net of associated expenses.
Trust and Wealth Advisory Fees	Trust and Wealth Advisory Fees — Trust and wealth advisory fees are recognized on the accrual basis.
Income Taxes	Income Taxes — 1st Source and its subsidiaries file a consolidated Federal income tax return. The provision for incomes taxes is based upon income in the consolidated financial statements, rather than amounts reported on the income tax return. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date. A valuation allowance, if needed, reduces deferred tax assets to the expected amount most likely to be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, the Company believes it is more likely than not that all of the deferred tax assets will be realized. The Company uses the deferral method of accounting on investments that generate investment tax credits. Under this method, the investment tax credits are recognized as a reduction to the related asset. The expense on certain qualified affordable housing investments is included in Tax Expense on the Consolidated Statements of Income. Positions taken in the tax returns may be subject to challenge by the taxing authorities upon examination. Uncertain tax positions are initially recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions are both initially and subsequently measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement with the tax authority, assuming full knowledge of the position and all relevant facts. The Company provides for interest and, in some cases, penalties on tax positions that may be challenged by the taxing authorities. Interest expense is recognized beginning in the first period that such interest would begin accruing. Penalties are recognized in the period that the Company claims the position in the tax return. Interest and penalties on income tax uncertainties are classified within Income Tax Expense on the Consolidated Statements of Income.
Net Income Per Common Share	Net Income Per Common Share — Earnings per share is computed using the two-class method. Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted-average number of shares of common stock outstanding, excluding participating securities. Diluted earnings per common share is computed by using the weighted-average number of shares determined for the basic earnings per share calculation plus the dilutive effect of stock compensation using the treasure stock method.
Stock-Based Employee Compensation	Stock-Based Employee Compensation — The Company recognizes stock-based compensation as compensation cost on the Consolidated Statements of Income based on their fair values on the measurement date, which, for its purposes, is the date of grant. The Company recognizes forfeitures as they occur.
Segment Information	Segment Information — 1st Source has one principal business segment, commercial banking. While our chief decision makers monitor the revenue streams of various products and services, the identifiable segments’ operations are managed and financial performance is evaluated on a company-wide basis. Accordingly, all of the Company’s financial service operations are considered to be aggregated in one reportable operating segment.
Derivative Financial Instruments	Derivative Financial Instruments — The Company occasionally enters into derivative financial instruments as part of its interest rate risk management strategies. These derivative financial instruments consist primarily of interest rate swaps. All derivative instruments are recorded on the Consolidated Statements of Financial Condition, as either an asset or liability, at their fair value. The accounting for the gain or loss resulting from the change in fair value depends on the intended use of the derivative. For a derivative used to hedge changes in fair value of a recognized asset or liability, or an unrecognized firm commitment, the gain or loss on the derivative will be recognized in earnings together with the offsetting loss or gain on the hedged item. This results in an earnings impact only to the extent that the hedge is ineffective in achieving offsetting changes in fair value. If it is determined that the derivative instrument is not highly effective as a hedge, hedge accounting is discontinued and the adjustment to fair value of the derivative instrument is recorded in earnings. For a derivative used to hedge changes in cash flows associated with forecasted transactions, the gain or loss on the effective portion of the derivative will be deferred, and reported as accumulated other comprehensive income, a component of shareholders’ equity, until such time the hedged transaction affects earnings. For derivative instruments not accounted for as hedges, changes in fair value are recognized in noninterest income/expense on the Consolidated Statements of Income. Deferred gains and losses from derivatives that are terminated and were in a cash flow hedge are amortized over the shorter of the original remaining term of the derivative or the remaining life of the underlying asset or liability.
Fair Value Measurements	Fair Value Measurements — The Company records certain assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Securities available for sale, mortgage loans held for sale, and derivative instruments are carried at fair value on a recurring basis. Fair value measurements are also utilized to determine the initial value of certain assets and liabilities, to perform impairment assessments, and for disclosure purposes. The Company uses quoted market prices and observable inputs to the maximum extent possible when measuring fair value. In the absence of quoted market prices, various valuation techniques are utilized to measure fair value. When possible, observable market data for identical or similar financial instruments are used in the valuation. When market data is not available, fair value is determined using valuation models that incorporate management’s estimates of the assumptions a market participant would use in pricing the asset or liability. Fair value measurements are classified within one of three levels based on the observability of the inputs used to determine fair value, as follows: Level 1 — The valuation is based on quoted prices in active markets for identical instruments. Level 2 — The valuation is based on observable inputs such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 — The valuation is based on unobservable inputs that are supported by minimal or no market activity and that are significant to the fair value of the instrument. Level 3 valuations are typically performed using pricing models, discounted cash flow methodologies, or similar techniques that incorporate management’s own estimates of assumptions that market participants would use in pricing the instrument, or valuations that require significant management judgment or estimation.
Reclassifications	Reclassifications — Certain amounts in the prior periods consolidated financial statements have been reclassified to conform with the current year presentation. These reclassifications had no effect on total assets, shareholders’ equity or net income as previously reported.

Modification programs focused on extending maturity dates or modifying payment patterns with most TDRs experiencing a combination of concessions. The modifications did not result in the contractual forgiveness of principal or interest. The TDRs during 2020 were the result of issues that predated the COVID-19 pandemic.
