Accounting Policies [Abstract] |
Description of Business | Description of Business The Company was incorporated on September 15, 2005, and consummated a plan of exchange on March 21, 2006, by which the Company became a bank holding company and 100% owner of First Internet Bank of Indiana (the “Bank”). The Bank offers a wide range of commercial, small business, consumer and municipal banking products and services. The Bank conducts its consumer and small business deposit operations primarily through digital channels on a nationwide basis and has no traditional branch offices. The Bank is subject to competition from other financial institutions. The Bank is regulated by certain state and federal agencies and undergoes periodic examinations by those regulatory authorities. The Bank has three wholly owned subsidiaries. JKH Realty Services, LLC was established on August 20, 2012 as a single member limited liability company wholly owned by the Bank to manage other real estate owned properties as needed. First Internet Public Finance Corp., a wholly-owned subsidiary of the Bank, was incorporated on March 6, 2017 and was established to provide municipal finance lending and leasing products to government entities and to purchase, manage, service, and safekeep municipal securities. SPF15, Inc., a wholly-owned subsidiary of the Bank, was incorporated on August 31, 2018 and was established to acquire and hold real estate.
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of the Company and its direct and indirect subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company’s business activities are currently limited to one reporting unit and reportable segment, which is commercial banking. Variable Interest Entity (“VIE”) The Company also evaluates its relationships with other entities to identify whether they represent a VIE. The Company is considered to hold a controlling financial interest in a VIE when it is the primary beneficiary. As described in applicable accounting standards, the primary beneficiary consolidates the VIE. A primary beneficiary has both: 1) the power to direct the activities that most significantly impact the entity’s economic performance; and 2) and the obligation to absorb losses of, or the right to receive benefits from, an entity that could potentially be significant to the entity. The Company considers all of its economic interests in the VIE when determining whether it has the obligation to absorb losses or the right to receive benefits from the VIE. Certain equity investments held by the Company meet the criteria of a VIE. See Note 3 for additional information on the Company’s equity investments and VIEs.
Segment Information | Segment Information The Company operates as a single reportable segment. While there are several lines of business within the operating segment, they are closely interrelated and cannot operate independently. Accordingly, the Chief Operation Decision Maker (“CODM”) evaluates operations and financial performance on a Company-wide basis and all of the Company’s operations are aggregated in one reportable operating segment. See Note 22 for additional segment information.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company utilizes processes that involve the use of significant estimates and the judgment of management in determining the amount of the Company’s allowance for credit losses (“ACL”). Actual results could differ from those estimates.
Securities | Securities The Company classifies its securities in one of three categories and accounts for the investments as follows: •Securities that the Company has the positive intent and ability to hold to maturity are classified as “held-to-maturity” and reported at amortized cost. •Securities that are acquired and held principally for the purpose of selling them in the near term with the objective of generating economic profits on short-term differences in market characteristics are classified as “trading securities” and reported at fair value, with unrealized gains and losses included in earnings. The Company had no securities classified as “trading securities” at December 31, 2025 or 2024. •Securities not classified as either “held-to-maturity” or “trading securities” are classified as “available-for-sale” and reported at fair value, with unrealized gains and losses, after applicable taxes, excluded from earnings and reported in a separate component of shareholders’ equity. Interest and dividend income, adjusted by amortization of premium or discount, is included in earnings using the effective interest rate method. Purchases and sales of securities are recorded in the consolidated balance sheets on the trade date. Gains and losses from the sale or disposal of securities are recognized as of the trade date in the consolidated statements of operations for the period in which securities are sold or otherwise disposed of. Gains and losses on sales of securities are determined using the specific-identification method.
Loans Held for Sale | Loans Held-for-Sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to noninterest income. Gains and losses on loan sales are recorded in noninterest income, and direct loan origination costs and fees are deferred at origination of the loan and are recognized in noninterest income upon sale of the loan.
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. Interest income on loans is accrued as earned using the interest method based on unpaid principal balances, except for interest on loans in nonaccrual status. Interest on loans in nonaccrual status is recorded as a reduction of loan principal when received. Premiums and discounts are amortized using the effective interest method. Loan fees, net of certain direct origination costs, primarily salaries and wages, are deferred and amortized to interest income as a yield adjustment over the life of the loan. The Company also earns noninterest income through a variety of financial and transaction services provided to commercial and consumer clients such as sales of the government-guaranteed portion of U.S. Small Business Administration loans, loan servicing revenue, deposit accounts, debit cards, mortgage banking and portfolio loan sales. 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.
Loans | Loans Loans that management intends to hold until maturity are reported at their outstanding principal balance adjusted for unearned income, charge-offs, the ACL, any unamortized deferred fees or costs on originated loans, any unamortized premiums or discounts on purchased loans and any carrying value adjustments related to terminated interest rate swaps associated with loans. For loans recorded at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are recorded in accordance with our revenue recognition policy. ASU 2016 - 13 On January 1, 2023, the Company adopted ASU 2016-03 Financial Instruments - Credit losses (“ASC 326”): Measurement of Credit Losses on Financial Instruments, as amended, which replaces the incurred loss methodology with an expected credit loss (“CECL”) methodology. The CECL estimate is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures, including loan commitments, standby letters of credit, financial guarantees and other similar instruments. Additionally, ASC 326 resulted in changes to the accounting for available-for-sale debt securities. The Company adopted ASC 326 for all financial assets measured at amortized cost, available-for-sale securities and off-balance sheet credit exposures. Results for reporting periods beginning after January 1, 2023 are presented under ASC 326, while prior period amounts continue to be reported in accordance with previously applicable U.S. GAAP. The Company recorded a net decrease to retained earnings of $4.5 million as of January 1, 2023 for the cumulative effect of adopting ASC 326. The net adjustment to the ACL includes $2.3 million related to loans, $1.9 million related to off-balance sheet credit exposures and $0.3 million related to held-to-maturity debt securities. Modified Loans to Borrowers Experiencing Financial Difficulty The Company may make modifications to certain loans in order to alleviate temporary difficulties in the borrower’s financial condition and/or constraints on the borrower’s ability to repay the loan, and to minimize potential losses to the Company. Modifications may include changes in the amortization terms of the loan, reductions in interest rates, acceptance of interest only payments, and/or reductions to the outstanding loan balance. Such loans may be placed on nonaccrual status when there is doubt concerning the full repayment of principal and interest or the loan has been delinquent for a period of 90 days or more. These loans may be returned to accrual status when all contractual amounts past due have been brought current, and the borrower’s performance under the modified terms of the loan agreement and the ultimate collectability of all contractual amounts due under the modified terms is no longer in doubt. Nonaccrual Loans Any loan which becomes 90 days delinquent or for which the full collection of principal and interest may be in doubt will be considered for nonaccrual status. At the time a loan is placed on nonaccrual status, all accrued but unpaid interest will be reversed from interest income. Placing a loan on nonaccrual status does not relieve the borrower of the obligation to repay interest. A loan placed on nonaccrual status may be restored to accrual status when all delinquent principal and interest has been brought current, and the Company expects full payment of the remaining contractual principal and interest. Individually Evaluated Loans A loan is individually evaluated, when, based on current information or events, it is probable that the Company will be unable to collect all amounts due (principal and interest) according to the contractual terms of the loan agreement. Payments with delays not exceeding 90 days outstanding generally are not individually evaluated. Certain nonaccrual and substantially all delinquent loans more than 90 days past due may be individually evaluated. Generally, loans are placed on nonaccrual status at 90 days past due and accrued interest is reversed against earnings, unless the loan is well secured and in the process of collection. The accrual of interest on individually evaluated and nonaccrual loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due. Individually evaluated loans include nonperforming loans and also include loans where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance, or other actions intended to maximize collection. Accounting Standards Codification (“ASC”) Topic 310, Receivables, requires that individually evaluated loans be measured based on the present value of expected future cash flows discounted at the loans’ effective interest rates or the fair value of the underlying collateral, less costs to sell, and allows existing methods for recognizing interest income. Policy for Charging Off Loans The Company’s policy is to charge off a loan at any point in time when it no longer can be considered a bankable asset, meaning collectible within the parameters of policy. A secured loan is generally charged down to the estimated fair value of the collateral, less costs to sell, no later than when it is 120 days past due as to principal or interest. An unsecured loan generally is charged off no later than when it is 180 days past due as to principal or interest. A home improvement loan generally is charged off no later than when it is 90 days past due as to principal or interest.
Allowance for Credit Losses (ACL) | ACL - Available-For-Sale (“AFS”) Debt Securities For AFS debt 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 the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For AFS 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, such as interest rates or market conditions. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an ACL is recorded. Changes in the ACL are recorded as a provision for, or recovery of, credit loss expense. Losses are charged against the allowance when management believes that uncollectibility of an AFS debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. ACL - Held-To-Maturity (“HTM”) Debt Securities Management measures expected credit losses on HTM debt securities on a collective basis by major security type. Accrued interest receivable on HTM debt securities are excluded from the estimate of credit losses. The Company made the accounting policy election to not measure an ACL for accrued interest. Accrued interest deemed uncollectible will be written off through interest income. The HTM securities portfolio includes municipal securities, residential mortgage-backed-securities, commercial mortgage-backed securities and corporate securities. All residential and commercial mortgage-backed securities are U.S. government issued or sponsored and substantially all municipal and corporate securities are rated investment grade or above. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. ACL - Loans The ACL for loans represents management's estimate of all expected credit losses over the expected life of the Company’s existing loan portfolio. Management estimates the ACL balance using relevant available information about the collectability of cash flows, from internal and external sources, including historical information relating to past events, current conditions, and reasonable and supportable forecasts of future economic conditions. When the Company is unable to forecast future economic events, management may revert to historical information. Accrued interest receivable on loans are excluded from the estimate of credit losses. The Company made the accounting policy election to not measure an ACL for accrued interest receivable. Accrued interest deemed uncollectible will be written off through interest income. ACL - Loans - Collectively Evaluated The ACL is measured on a collective pool basis when similar risk characteristics exist. The Company utilizes a discounted cash flow (“DCF”) method to estimate the quantitative portion of the allowance for credit losses for loans evaluated on a collective pooled basis. For each segment, a loss driver analysis is performed in order to identify loss drivers and create a regression model for use in forecasting cash flows. In creating the DCF model, the Company has established a one-year reasonable and supportable forecast period with a one-year straight line reversion to the long-term historical average. Due to its limited loss history, the Company elected to use peer data in certain loan segments for a more accurate calculation. Key inputs into the DCF model include loan-level detail, including the amortized cost basis of individual loans, payment structure, loss history, and forecasted loss drivers. The Company utilizes a third party to provide economic forecasts under various scenarios, which are assessed quarterly considering the scenarios in the context of the current economic environment and loss risk. Expected credit losses are estimated over the contractual term of the loans and adjusted for prepayments when appropriate. The contractual term excludes extensions, renewals, and modifications unless the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company. Additional key assumptions in the DCF model include the probability of default (“PD”), loss given default (“LGD”), and prepayment/curtailment rates. The Company utilizes the model-driven PD and a LGD derived from a method referred to as Frye Jacobs. The Frye Jacobs method is a mathematical formula that traces the relationship between LGD and PD over time and projects the LGD based on the level of PD forecasted. In all cases, the Frye Jacobs method is utilized to calculate LGD during the forecast period, reversion period and long-term historical average. Prepayment and curtailment rates were calculated through third party analysis of the Company’s own data. Qualitative factors for the DCF include the following: •Changes in lending policies and procedures, including changes in underwriting standards and collections, charge-offs and recovery practices •Changes in international, national, regional and local economic conditions •Changes in the nature and volume of the portfolio and terms of loans •Changes in the experience, depth and ability of lending management •Changes in the volume and severity of past due loans and other similar conditions •Changes in the quality of the Company’s loan review system •Changes in the value of underlying collateral for collateral dependent loans •The existence and effect of any concentrations of credit and changes in the levels of such concentrations •The effect of other external factors (e.g. competition, legal and regulatory requirements) on the level of estimated credit losses ACL - Loans - Individually Evaluated Loans that do not share risk characteristics are evaluated on an individual basis and are excluded from the collective evaluation. Individual analysis will establish a specific reserve for loans, if necessary. Specific reserves on nonaccrual loans are typically based on management’s best estimate of the fair value of collateral securing these loans, adjusted for selling costs as necessary, assessment of guarantor strength, or the value of the government-guaranteed portion of U.S. Small Business Administration loans. ACL - Off-Balance Sheet Credit Exposures The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The ACL for off-balance sheet credit exposure is recorded as a liability and adjusted as a provision for credit loss expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. Funding rates are based on a historical analysis of the Company’s portfolio, while estimates of credit losses are determined using the same loss rates as funded loans.
Regulatory Capital | Regulatory Capital As permitted by the federal banking regulatory agencies, the Company has elected the option to delay the impact of the day one adoption of ASC 326. Refer to “Note 14: Regulatory Capital Requirements” for details of the phase-in transition adjustments.
Provision for Credit Losses | Provision for Credit Losses A provision for estimated credit losses is charged to income based upon management’s evaluation of the potential losses. Such an evaluation, which includes a review of all loans for which full repayment may not be reasonably assured, considers, among other matters, the estimated net realizable value of the underlying collateral, an assessment of guarantor strength, or the value of the government-guaranteed portion of U.S. Small Business Administration loans, as applicable, economic conditions, loan loss experience, and other factors that are particularly susceptible to changes that could result in a material adjustment in the near term. While management attempts to use the best information available in making its evaluations, future ACL adjustments may be necessary if conditions change substantially from the assumptions used in making the evaluations.
Federal Home Loan Bank (FHLB) of Indianapolis Stock | Federal Home Loan Bank (“FHLB”) of Indianapolis Stock Federal law requires a member institution of the FHLB system to hold common stock of its district FHLB according to a predetermined formula. This investment is stated at cost, which represents redemption value, and may be pledged as collateral for FHLB advances.
Property and Equipment | Premises and Equipment Premises and equipment is stated at cost, less accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives, which range from three to five years for software and equipment, ten years for land improvements, and 39 years for buildings.
Other Real Estate Owned | Other Real Estate Owned Other real estate owned represents real estate acquired through foreclosure or deed in lieu of foreclosure. When property is acquired, it is recorded at its fair value, less estimated costs to sell, at the date of acquisition with any resulting write-down charged against the ACL. A valuation allowance is recorded through noninterest expense for any subsequent deterioration of the property. Costs relating to holding and maintaining the property are recorded to noninterest expense as incurred. Upon the sale of other real estate owned the gain or loss, as applicable, is recorded to noninterest income.
Derivative Financial Instruments | Derivative Financial Instruments The Company uses derivative financial instruments to help manage exposure to interest rate risk and the effects that changes in interest rates may have on net income and the fair value of assets and liabilities. The Company enters into interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. Additionally, prior to the Company’s decision to exit its consumer mortgage business in the first quarter 2023, we entered into forward contracts related to our mortgage banking business to hedge the exposures we had from commitments to extend new residential mortgage loans to our customers and from our mortgage loans held-for-sale. The forward contracts were entered into in order to economically hedge the effect of changed interest rates resulting from the Company’s commitment to fund the loans. Designating an interest rate swap as an accounting hedge allows the Company to recognize gains and losses in the income statement within the same period that the hedged item affects earnings. The Company includes the gain or loss on the hedged items in the same line item as the offsetting loss or gain on the related interest rate swaps. For derivative instruments that are designated and qualify as cash flow hedges, any gains or losses related to changes in fair value are recorded in accumulated other comprehensive loss, net of tax. The fair value of interest rate swaps with a positive fair value are reported in accrued income and other assets in the consolidated balance sheets while interest rate swaps with a negative fair value are reported in accrued expenses and other liabilities in the consolidated balance sheets. The interest rate lock commitments (“IRLCs”) and forward contracts are not designated as accounting hedges and are recorded at fair value with changes in fair value reflected in noninterest income in the consolidated statements of operation. The fair value of these derivative instruments with a positive fair value are reported in accrued income and other assets in the consolidated balance sheets, while derivative instruments with a negative fair value are reported in accrued expenses and other liabilities in the consolidated balance sheets.
Fair Value Measurements | Fair Value Measurements The Company records or discloses certain assets and liabilities at fair value. ASC Topic 820, Fair Value Measurements, defines fair value 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. Fair value measurements are classified within one of three levels in a valuation hierarchy. ASC Topic 820 describes three levels of inputs that may be used to measure fair value: Level 1 Quoted prices in active markets for identical assets or liabilities Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities
Income Taxes | Income Taxes Deferred income tax assets and liabilities reflect the impact of temporary differences between amounts of assets and liabilities for financial reporting purposes and the basis of such assets and liabilities as measured by tax laws and regulations. Deferred income tax expense or benefit is based upon the change in deferred tax assets and liabilities from period to period, subject to an ongoing assessment of realization of deferred tax assets. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company files income tax returns in the U.S. federal, Indiana, and other state jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state and local examinations by tax authorities for years before 2022. ASC Topic 740-10, Accounting for Uncertainty in Income Taxes, prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company did not identify any material uncertain tax positions that it believes should be recognized in the consolidated financial statements.
Earnings Per Share | Earnings Per Share (Loss) earnings per share of common stock is based on the weighted average number of basic shares and dilutive shares outstanding during the year.
Share-based Compensation | Share-based Compensation The Company has a share-based compensation plan using the fair value recognition provisions of ASC Topic 718, Compensation - Stock Compensation. The plan is described more fully in Note 11.
Comprehensive Income | Comprehensive (Loss) Income Comprehensive (loss) income consists of net (loss) income and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on securities available-for-sale, unrealized gains and losses on the transfer of securities available-for-sale to securities held-to-maturity, and unrealized gains and losses on cash flow hedges. Reclassification adjustments have been determined for all components of other comprehensive income (loss) reported in the consolidated statements of shareholders’ equity.
Statements of Cash Flows | Statements of Cash Flows Cash and cash equivalents are defined to include cash on-hand, noninterest and interest-bearing amounts due from other banks and federal funds sold. Generally, federal funds are sold for one-day periods. The Company reports net cash flows for customer loan transactions and deposit transactions.
Bank-Owned Life Insurance | Bank-Owned Life Insurance Bank-owned life insurance policies are carried at their cash surrender value. The Company recognizes tax-free income from the periodic increases in the cash surrender value of these policies and from death benefits.
Goodwill | Goodwill Goodwill is assessed for impairment annually as of August 31, or more frequently if events occur or circumstances change that indicate an impairment may exist. When assessing goodwill for impairment, first, a qualitative assessment can be made to determine whether it is more likely than not that the estimated fair value of a reporting unit is less than its estimated carrying value. If the results of the qualitative assessment are not conclusive, a quantitative goodwill test is performed. Alternatively, a quantitative goodwill test can be performed without performing a qualitative assessment.
Servicing Asset | Servicing Asset The servicing asset is related to small business lending and single tenant lease financing loans sold. The servicing asset is recognized at the time of sale when servicing is retained and the income statement effect is recorded in loan servicing revenue. Servicing assets are recorded at fair value in accordance with ASC 860. Fair value is based on a third-party valuation model that calculates the present value of net servicing revenue.
Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Adopted Accounting Standards ASU 2023-02 - Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (March 2023) In March 2023, the FASB issued ASU No. 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. This ASU permits companies to account for tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. The Company adopted this guidance on January 1, 2024 and it did not have a material impact on its consolidated financial statements. ASU 2023-09 - Income Taxes (Topic 740): Improvements to Income Tax Disclosures (December 2023) In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. This ASU enhances the transparency and usefulness of income tax disclosures, which addresses investor requests for more transparency about income tax disclosures related primarily to the rate reconciliation and income taxes paid information. The Company adopted this guidance on January 1, 2025 and it did not have a material impact on its consolidated financial statements. Newly Issued But Not Yet Effective Accounting Standards ASU 2024-03 - Income Statement-Reporting Comprehensive Income - Expense Disaggregations Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (November 2024) In November 2024, the FASB issued ASU No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregations Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This ASU requires additional disclosures of the nature of expenses included in the Company’s income statement. The new standard requires disclosures about specific types of expenses included the income statement. The guidance is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.
