Securities: Securities available-for-sale are valued primarily by a third party pricing service. The fair values of securities available-for-sale are determined on a recurring basis by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or pricing models which utilize significant observable inputs such as matrix pricing. This is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). These models utilize the market approach with standard inputs that include, but are not limited to benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. For certain municipal securities that are not rated and observable inputs about the specific issuer are not available, fair values are estimated using observable data from other municipal securities presumed to be similar or other market data on other non-rated municipal securities (Level 3 inputs).

The Company’s Finance Department, which is responsible for all accounting and SEC disclosure compliance, and the Company’s Treasury Department, which is responsible for investment portfolio management and asset/liability modeling, are the two areas that determine the Company’s valuation policies and procedures. Both of these areas report directly to the Executive Vice President and Chief Financial Officer of the Company. For assets or liabilities that may be considered for Level 3 fair value measurement on a recurring basis, these two departments and the Executive Vice President and Chief Financial Officer determine the appropriate level of the assets or liabilities under consideration. If there are new assets or liabilities that are determined to be Level 3 by this group, the Risk Management Committee of the Company and the Audit Committee of the Board are made aware of such assets at their next scheduled meeting.

Securities pricing is obtained from a third party pricing service and all security prices are tested annually against prices from another third party provider and reviewed with a market value price tolerance variance that varies by sector: municipal securities +/-5%, government MBS/CMO +/-3% and U.S. treasuries +/-1%. If any securities fall outside the tolerance threshold and have a variance of $100,000 or more, a determination of materiality is made for the amount over the threshold. Any security that would have a material threshold difference would be further investigated to determine why the variance exists and if any action is needed concerning the security pricing for that individual security. Changes in market value are reviewed monthly in aggregate by security type and any material changes are reviewed to determine why they exist. At least annually, the pricing methodology of the pricing service is received and reviewed to support the fair value levels used by the Company. A detailed pricing evaluation is requested and reviewed on any security determined to be fair valued using unobservable inputs by the pricing service.

Interest rate swap derivatives: Our derivatives are traded in an over-the-counter market where quoted market prices are not always available. Therefore, the fair values of derivatives are determined using quantitative models that utilize multiple market inputs. The inputs will vary based on the type of derivative, but could include interest rates, prices and indices to generate continuous yield or pricing curves, prepayment rates, and volatility factors to value the position. The majority of market inputs are actively quoted and can be validated through external sources, including brokers, market transactions and third-party pricing

Collateral dependent loans: Collateral dependent loans with specific allocations of the allowance for credit losses are generally based on the fair value of the underlying collateral when repayment is expected solely from the collateral. Fair value is determined using several methods. Generally, the fair value of real estate is based on appraisals by qualified third party appraisers. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and result in a Level 3 classification of the inputs for determining fair value. In addition, the Company’s management routinely applies internal discount factors to the value of appraisals used in the fair value evaluation of collateral dependent loans. The deductions to the appraisals take into account changing business factors and market conditions, as well as value impairment in cases where the appraisal date predates a likely change in market conditions. Commercial real estate is generally discounted from its appraised value by 30-50% with the higher discounts applied to real estate that is determined to have a thin trading market or to be specialized collateral. In addition to real estate, the Company’s management evaluates other types of collateral as follows: (a) raw materials inventory is discounted from its cost or book value by 40-60%, depending on the marketability of the goods; (b) finished goods are generally discounted by 40-60%, depending on the ease of marketability, cost of transportation or scope of use of the finished good; (c) work in process inventory is typically discounted by 60%-100%, depending on the length of manufacturing time, types of components used in the completion process, and the breadth of the user base; (d) equipment is valued at a percentage of depreciated book value or recent appraised value, if available, and is typically discounted at 20-50% after various considerations including age and condition of the equipment, marketability, breadth of use, and whether the equipment includes unique components or add-ons; and (e) marketable securities are discounted by 10%-30%, depending on the type of investment, age of valuation report and general market conditions. This methodology is based on a market approach and typically results in a Level 3 classification of the inputs for determining fair value.

Mortgage servicing rights: As of June 30, 2026, the value of the Company’s Level 3 servicing assets for residential mortgage loans (“MSRs”) was $1.5 million, carried at amortized cost and an immaterial valuation reserve. These residential mortgage loans have a weighted average interest rate of 4.0%, a weighted average maturity of 20 years and are secured by homes generally within the Company’s market area of Northern Indiana and Indianapolis. A third-party valuation is used to estimate fair value by stratifying the portfolios on the basis of certain risk characteristics, including loan type and interest rate. Impairment is estimated based on an income approach. The inputs used include estimates of prepayment speeds, discount rate, cost to service, escrow account earnings, contractual servicing fee income, ancillary income, late fees and float income. The most significant assumption used to value MSRs is prepayment rate. Prepayment rates are estimated based on published industry consensus prepayment rates. The most significant unobservable assumption is the discount rate. At June 30, 2026, the constant prepayment speed (“PSA”) used was 167 and used a discount rate of 9.5%. At December 31, 2025, the PSA used was 168 and the discount rate used was 9.5%.

Other real estate owned: Nonrecurring adjustments to certain commercial and residential real estate properties, classified as other real estate owned, are measured at the lower of carrying amount or fair value less costs to sell. Fair values are generally based on third party appraisals of the property and are reviewed by the Company’s internal appraisal officer. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable properties used to determine value. Such adjustments are usually significant and result in a Level 3 classification. In addition, the Company’s management may apply discount factors to the appraisals to take into account changing business factors and market conditions, as well as value impairment in cases where the appraisal date predates a likely change in market conditions. In cases where the carrying amount exceeds the fair value, less costs to sell, an impairment loss is recognized.
