Basis of Presentation and Changes in Significant Accounting Policies
Basis of Presentation and Changes in Significant Accounting Policies	Note 1 – Basis of Presentation and Changes in Significant Accounting Policies The accounting policies followed in the preparation of the interim consolidated financial statements are consistent with those used in the preparation of the annual financial information. The interim consolidated financial statements reflect all normal and recurring adjustments that are necessary, in the opinion of management, for a fair statement of results for the interim period presented. Results for the period ended September 30, 2024, are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. These interim consolidated financial statements and accompanying notes are unaudited and should be read in conjunction with the audited financial statements and notes included in Old Second Bancorp, Inc.’s (the “Company”) annual report on Form 10-K for the year ended December 31, 2023. Unless otherwise indicated, dollar amounts in the tables contained in the notes to the consolidated financial statements are in thousands. Certain items in prior periods have been reclassified to conform to the current presentation. The Company’s consolidated financial statements are prepared in accordance with United States generally accepted accounting principles (“GAAP”) and follow general practices within the banking industry. Application of these principles requires management to make estimates, assumptions, and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the consolidated financial statements. Future changes in information may affect these estimates, assumptions, and judgments, which, in turn, may affect amounts reported in the consolidated financial statements. Recent Accounting Pronouncements The following is a summary of recent accounting pronouncements that have impacted or could potentially affect the Company : ASU 2023-06 Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative” ASU 2023-07 Segment Reporting (Topic 280): “Improvements to Reportable Segment Disclosures”. ASU 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures” ASU 2024-01 – Compensation - Stock Compensation (Topic 718) - Scope Application of Profits Interest and Similar Awards” ASU 2024-02 – Codification Improvements – Amendments to Remove References to the Concepts Statements Change in Significant Accounting Policies Significant accounting policies are presented in Note 1 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. These policies, along with the disclosures presented in the other financial statement notes and in this discussion, provide information on how significant assets and liabilities are valued in the consolidated financial statements and how those values are determined. During the third quarter of 2024, the Company had no changes to significant accounting policies or estimates. Subsequent Events On October 15, 2024, our Board of Directors declared a cash dividend of $0.06 per share of common stock payable on November 4, 2024, to stockholders of record as of October 25, 2024; dividends of $2.7 million were paid to stockholders on November 4, 2024.

Securities	Note 2 – Securities Investment Portfolio Management Our investment portfolio serves the liquidity needs and income objectives of the Company. While the portfolio serves as an important component of the overall liquidity management at the Bank, portions of the portfolio also serve as income producing assets. The size and composition of the portfolio reflects liquidity needs, loan demand and interest income objectives. Portfolio size and composition will be adjusted from time to time. While a significant portion of the portfolio consists of readily marketable securities to address liquidity, other parts of the portfolio may reflect funds invested pending future loan demand or to maximize interest income without undue interest rate risk. Investments are comprised of debt securities and non-marketable equity investments. Securities available-for-sale are carried at fair value. Unrealized gains and losses, net of tax, on securities available-for-sale are reported as a separate component of equity. This balance sheet component changes as interest rates and market conditions change. Unrealized gains and losses are not included in the calculation of regulatory capital.

Our assessment includes a review of the unrealized loss for each security issuance held; the financial condition and near-term prospects of the issuer, including external credit ratings and recent downgrades; and our ability and intent to hold the security for a period of time sufficient for a recovery in value. We also consider the extent to which the securities are issued by the federal government or its agencies, and any guarantee of issued amounts by those agencies. The portfolio continues to consist of a mix of fixed and floating-rate, high quality securities, largely rated AA (or better), displaying an overall effective duration of approximately 3.0 years. No credit losses were determined to be present as of September 30, 2024, as there was no credit quality deterioration noted. Therefore, no provision for credit losses on securities was recognized for the third quarter of 2024. The following table presents net realized gains (losses) on securities available-for-sale for three and six months ended: Three Months Ended Nine Months Ended September 30, September 30, Securities available-for-sale 2024 2023 2024 2023 Proceeds from sales of securities $ - $ 65,572 $ 5,331 $ 205,738 Gross realized gains on securities $ - $ - $ 1 $ - Gross realized losses on securities (1) (924) (1) (4,146) Net realized (losses) gains $ (1) $ (924) $ - $ (4,146) Income tax benefit on net realized losses $ - $ 260 $ - $ 1,165 Effective tax rate applied 0.0 % 28.1 % N/M 28.1 % N/M – Not meaningful.

It is the policy of the Company to review each prospective credit prior to making a loan in order to determine if an adequate level of security or collateral has been obtained. The type of collateral, when required, will vary from liquid assets to real estate. The Company seeks to ensure access to collateral, in the event of borrower default, through adherence to lending laws, the Company’s lending standards and credit monitoring procedures. Although the Bank makes loans primarily within its market area, there are no significant concentrations of loans where the customers’ ability to honor loan terms is dependent upon a single economic sector. The real estate related categories listed above represent 67.8% and 68.8% of the portfolio at September 30, 2024, and December 31, 2023, respectively, and include a mix of owner occupied and non-owner occupied commercial real estate, residential, construction and multifamily loans.

At September 30, 2024, our allowance for credit losses (“ACL”) on loans totaled $44.4 million, and our ACL on unfunded commitments, included in other liabilities, totaled $2.5 million. During the first nine months of 2024, we recorded net provision for credit losses on loans of $9.5 million based on historical loss rate updates driven by higher charge offs in commercial real estate-investor, downward risk rating migration, and our assessment of estimated future credit losses. The ACL on loans excludes an allowance for unfunded commitments of $2.5 million as of September 30, 2024, and $2.7 million as of both December 31, 2023, and September 30, 2023, which is recorded within other liabilities. Generally, the Bank considers a loan to be collateral dependent when, based on current information and events, it is probable that foreclosure could be initiated. Additionally, the Bank will review all loans meeting the criteria for individual analysis, to determine if repayment or satisfaction of the loan is expected through the sale of collateral. This will generally be the case for credits with high loan-to-values. Exceptions to this policy would include loans with guarantors or sponsors that have the means and willingness to support the obligation. Non-accruing loans with an outstanding balance of $500,000 or more are assessed on an individual loan level basis. When a financial asset is deemed collateral-dependent, the level of credit loss is measured by the difference between amortized cost of the financial asset and the fair value of collateral adjusted for estimated cost to sell. The Company had $50.2 million and $63.1 million of collateral dependent loans secured by real estate or business assets as of September 30, 2024, and December 31, 2023, respectively.

Credit Quality Indicators The Company categorizes loans into credit risk categories based on current financial information, overall debt service coverage, comparison to industry averages, historical payment experience, and current economic trends. This analysis includes loans with outstanding balances or commitments greater than $50,000 and excludes homogeneous loans such as home equity lines of credit and residential mortgages. Loans with a classified risk rating are reviewed quarterly regardless of size or loan type. The Company uses the following definitions for classified risk ratings: Special Mention. Substandard. Doubtful. Credits that are not covered by the definitions above are pass credits, which are not considered to be adversely rated. Credit quality indicators by loan segment and loan origination date at September 30, 2024, were as follows: 2024 2023 2022 2021 2020 Prior Revolving Loans Revolving Loans Converted To Term Loans Total Commercial Pass $ 200,043 $ 230,428 $ 81,173 $ 23,250 $ 5,838 $ 7,264 $ 218,666 $ -

The Company enters into deposit sweep transactions where the transaction amounts are secured by pledged securities. These transactions consistently mature overnight from the transaction date and are governed by sweep repurchase agreements. All sweep repurchase agreements are treated as financings secured by U.S. government agencies and collateralized mortgage-backed securities, and had a carrying amount of $53.9 million at September 30, 2024, and $26.5 million at December 31, 2023. The fair value of the pledged collateral was $75.0 million at September 30, 2024, and $45.7 million at December 31, 2023. At September 30, 2024, there were no customers with secured balances exceeding 10% of stockholders’ equity. The Company’s borrowings at the FHLBC require the Bank to be a member and invest in the stock of the FHLBC. Total borrowings are generally limited to the lower of 35% of total assets or 60% of the book value of certain mortgage loans. As of September 30, 2024, the Bank had $335.0 million in short-term advances outstanding under the FHLBC, and $405.0 million in short-term advances as of December 31, 2023. FHLBC stock held at September 30, 2024, was valued at $15.3 million, and any potential FHLBC advances were collateralized by loans and securities with a principal balance of $1.40 billion, which carried a FHLBC-calculated combined collateral value of $953.0 billion. The Company had excess collateral of $653.0 million available to secure borrowings at September 30, 2024. In the second quarter of 2021, we issued $60.0 million in aggregate principal amount of our 3.50% Fixed-to-Floating Rate Subordinated Notes due April 15, 2031 (the “Notes”). The Company used the net proceeds from the offering for general corporate purposes. The Notes bear interest at a fixed annual rate of 3.50%, from and including the date of issuance to but excluding April 15, 2026, payable semi-annually in arrears. From and including April 15, 2026, to, but excluding the maturity date or early redemption date, the interest rate will reset quarterly to an interest rate per annum equal to three-month Term Secured Overnight Financing Rate (“SOFR”) (as defined by the Note) plus 273 basis points, payable quarterly in arrears. As of September 30, 2024, and December 31, 2023, we had $59.4 million of subordinated debentures outstanding, net of deferred issuance cost. The Company issued senior notes in December 2016 with a ten-year On February 24, 2020, the Company originated a $20.0 million three-year term note with a correspondent bank.

This note was included within Notes payable and other borrowings on the Consolidated Balance Sheets, and the remaining $9.0 million balance of the note was paid off on February 24, 2023. The Company also has an undrawn line of credit of $30.0 million with a correspondent bank to be used for short-term funding needs; advances under this line can be outstanding up to 360 days from the date of issuance. This line of credit has not been utilized since early 2019.

Junior Subordinated Debentures
Junior Subordinated Debentures	Note 7 – Junior Subordinated Debentures The Company issued $25.0 million of cumulative trust preferred securities through a private placement completed by an unconsolidated subsidiary, Old Second Capital Trust II, in April 2007. These trust preferred securities mature in 30 years, but subject to regulatory approval, can be called in whole or in part on a quarterly basis commencing June 15, 2017. The quarterly cash distributions on the securities were fixed at 6.77% through June 15, 2017, and now have a floating rate of 150 basis points over three-month SOFR. Upon conversion to a floating rate, a cash flow hedge was initiated which resulted in the total interest rate paid on the debt of 4.17% and 3.77% for the quarters ended September 30, 2024, and September 30, 2023, respectively. The Company issued a $25.8 million subordinated debenture to Old Second Capital Trust II in return for the aggregate net proceeds of this trust preferred offering. The interest rate and payment frequency on the debenture are equivalent to the cash distribution basis on the trust preferred securities. The junior subordinated debentures issued by the Company are disclosed on the Consolidated Balance Sheets, and the related interest expense for each issuance is included in the Consolidated Statements of Income. As of September 30, 2024, and December 31, 2023, the remaining unamortized debt issuance costs related to the junior subordinated debentures were less than $1,000 and are included as a reduction to the balance of the junior subordinated debentures on the Consolidated Balance Sheets. The remaining deferred issuance costs on the junior subordinated debentures related to the issuance of Old Second Capital Trust II will be amortized to interest expense over the remainder of the 30-year term of the notes and are included in the Consolidated Statements of Income.

Equity Compensation Plans
Equity Compensation Plans	Note 8 – Equity Compensation Plans Stock-based awards are outstanding under the Company’s 2019 Equity Incentive Plan, as amended and restated (the “2019 Plan”). The 2019 Plan was originally approved at the May 2019 annual stockholders’ meeting and authorized 600,000 shares, and at the May 2021 annual stockholders’ meeting, the Company obtained stockholder approval to increase the number of shares of common stock authorized for issuance under the 2019 Plan by 1,200,000 shares, from 600,000 shares to 1,800,000 shares. Following the approval of the 2019 Plan, no further awards will be granted under any other prior plan. The 2019 Plan authorizes the granting of qualified stock options, non-qualified stock options, restricted stock, restricted stock units, and stock appreciation rights (“SARs”). Awards may be granted to selected directors, officers, employees or eligible service providers under the 2019 Plan at the discretion of the Compensation Committee of the Company’s Board of Directors. As of September 30, 2024, 718,193 shares remained available for issuance under the 2019 Plan. The Company has granted only restricted stock units under the 2019 Equity Plan. Generally, restricted stock units granted under the 2019 Plan vest three years from the grant date, but the Compensation Committee of the Company’s Board of Directors has discretionary authority to change the terms of particular awards including the vesting schedule. Under the 2019 Plan, unless otherwise provided in an award agreement, upon the occurrence of a change in control, all equity awards then held by the participant will become fully exercisable immediately if, and all stock awards and cash incentive awards will become fully earned and vested immediately if, (i) the 2019 Plan is not an obligation of the successor entity following a change in control or (ii) the 2019 Plan is an obligation of the successor entity following a change in control and the participant incurs a termination of service without cause or for good reason following the change in control. Notwithstanding the immediately preceding sentence, if the vesting of an award is conditioned upon the achievement of performance measures, then such vesting will generally be subject to the following: if, at the time of the change in control, the performance measures are less than 50% attained (pro rata based upon the time of the period through the change in control), the award will become vested and exercisable on a fractional basis with the numerator being equal to the percentage of attainment and the denominator being 50%; and if, at the time of the change in control, the performance measures are at least 50% attained (pro rata based upon the time of the period through the change in control), the award will become fully earned and vested immediately upon the change in control. Awards of restricted stock under the 2019 Plan generally entitle holders to voting and dividend rights upon grant and are subject to forfeiture until certain restrictions have lapsed including employment for a specific period. Awards of restricted stock units under the 2019 Plan are also subject to forfeiture until certain restrictions have lapsed including employment for a specific period, but do not entitle holders to voting rights until the restricted period ends and shares are transferred in connection with the units. There were 339,235 and 240,149 restricted stock units issued under the 2019 Plan during the nine months ended September 30, 2024, and September 30, 2023, respectively. Compensation expense is recognized over the vesting period of the restricted stock units based on the market value of the award on the issue date. Total compensation cost that has been recorded for the 2019 Plan was $3.1 million for the nine months ended September 30, 2024, and $2.7 million for the nine months ended September 30, 2023. A summary of changes in the Company’s unvested restricted awards for the nine months ended September 30, 2024, is as follows: September 30, 2024 Weighted Restricted Average Stock Shares Grant Date and Units Fair Value Unvested at January 1 709,237 $ 14.26 Granted 339,235 13.44 Vested (211,469) 11.39 Forfeited (8,954) 14.09 Unvested at September 30 828,049 $ 14.65 Total unrecognized compensation cost of restricted awards was $5.2 million as of September 30, 2024, which is expected to be recognized over a weighted-average period of 1.86 years.

Regulatory & Capital Matters
Regulatory & Capital Matters	Note 10 Regulatory & Capital Matters The Bank is subject to the risk-based capital regulatory guidelines, which include the methodology for calculating the risk-weighted Bank assets, developed by the Office of the Comptroller of the Currency (the “OCC”) and the other bank regulatory agencies. In connection with the current risk-based capital regulatory guidelines, the Bank’s Board of Directors has established an internal guideline requiring the Bank to maintain a Tier 1 leverage capital ratio at or above eight percent (8%) and a total risk-based capital ratio at or above twelve percent (12%). At September 30, 2024, the Bank exceeded those thresholds. At September 30, 2024, the Bank’s Tier 1 capital leverage ratio was 11.46%, an increase of 105 basis points from December 31, 2023, and is above the 8.00% objective. The Bank’s total capital ratio was 14.45%, an increase of 121 basis points from December 31, 2023, and also above the objective of 12.00%. Bank holding companies are generally required to maintain minimum levels of capital in accordance with capital guidelines implemented by the Board of Governors of the Federal Reserve System. The general bank and holding company capital adequacy guidelines are shown in the accompanying table, as are the capital ratios of the Company and the Bank, as of September 30, 2024, and December 31, 2023. The Basel III Rules are applicable to all banking organizations that are subject to minimum capital requirements, including federal and state banks and savings and loan associations, as well as to bank and savings and loan holding companies, other than “small bank holding companies,” which are generally holding companies with consolidated assets of less than $3.0 billion. A detailed discussion of the Basel III Rules is included in Part I, Item 1 of the Company’s Form 10-K for the year ended December 31, 2023, under the heading “Supervision and Regulation.” At September 30, 2024, and December 31, 2023, the Company, on a consolidated basis, exceeded the minimum thresholds to be considered “well capitalized” under current regulatory defined capital ratios. Capital levels and industry defined regulatory minimum required levels are as follows: Minimum Capital Well Capitalized Adequacy with Capital Under Prompt Corrective Actual Conservation Buffer, if applicable 1 Action Provisions 2 Amount Ratio Amount Ratio Amount Ratio September 30, 2024 Common equity tier 1 capital to risk weighted assets Consolidated $ 609,778 12.86 % $ 331,916 7.00 % N/A N/A Old Second Bank 638,983 13.49 331,570 7.00 $ 307,887 6.50 % Total capital to risk weighted assets Consolidated 740,371 15.62 497,689 10.50 N/A N/A Old Second Bank 684,576 14.45 497,443 10.50 473,755 10.00 Tier 1 capital to risk weighted assets Consolidated 634,778 13.39 402,958 8.50 N/A N/A Old Second Bank 638,983 13.49 402,621 8.50 378,937 8.00 Tier 1 capital to average assets Consolidated 634,778 11.38 223,121 4.00 N/A N/A Old Second Bank 638,983 11.46 223,031 4.00 278,788 5.00 December 31, 2023 Common equity tier 1 capital to risk weighted assets Consolidated $ 547,721 11.37 % $ 337,207 7.00 % N/A N/A Old Second Bank 592,413 12.32 336,598 7.00 $ 312,556 6.50 % Total capital to risk weighted assets Consolidated 677,076 14.06 505,640 10.50 N/A N/A Old Second Bank 636,768 13.24 504,990 10.50 480,943 10.00 Tier 1 capital to risk weighted assets Consolidated 572,721 11.89 409,430 8.50 N/A N/A Old Second Bank 592,413 12.32 408,727 8.50 384,684 8.00 Tier 1 capital to average assets Consolidated 572,721 10.06 227,722 4.00 N/A N/A Old Second Bank 592,413 10.41 227,632 4.00 284,540 5.00 1 Amounts are shown inclusive of a capital conservation buffer of 2.50%. 2 The prompt corrective action provisions are only applicable at the Bank level. The Bank exceeded the general minimum regulatory requirements to be considered “well capitalized.” As part of its response to the impact of the COVID-19 pandemic, in the first quarter of 2020, U.S. federal regulatory authorities issued an interim final rule that provided banking organizations that adopted the Current Expected Credit Losses (“CECL”) methodology during the 2020 calendar year with the option to delay for two years the estimated impact of CECL on regulatory capital relative to regulatory capital determined under the prior incurred loss methodology, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided during the initial two-year delay (i.e., a five-year transition in total). In connection with our adoption of CECL on January 1, 2020, we elected to utilize the five-year CECL transition. As of September 30, 2024, the above capital measures of the Company include $951,000, which is the modified CECL transition adjustment. Dividend Restrictions In addition to the above requirements, banking regulations and capital guidelines generally limit the amount of dividends that may be paid by a bank without prior regulatory approval. Under these regulations, the amount of dividends that may be paid in any calendar year is limited to the current year’s profits, combined with the retained profit of the previous two years, subject to the capital requirements described above. As of September 30, 2024, the Bank had capacity to pay dividends of $117.0 million to the Company without prior regulatory approval. Pursuant to the Basel III rules, the Bank must keep a capital conservation buffer of 2.50% above the regulatory minimum capital requirements, which must consist entirely of Common Equity Tier 1 capital in order to avoid additional limitations on capital distributions and certain other payments.

Fair Value Measurements

Fair Value Measurements	Sep. 30, 2024
Fair Value Measurements
Fair Value Measurements	Note 11 Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy established by the Company also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Three levels of inputs that may be used to measure fair value are: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Company has the ability to access as of the measurement date. Level 2: Significant observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a company’s own view about the assumptions that market participants would use in pricing an asset or liability. There were no transfers between levels during the nine-month period ended September 30, 2024, however the Company reclassified one states and political subdivisions security to an asset-backed security in all periods presented. During the nine-month period ended September 30, 2023, $14.9 million of asset-backed securities and $6.8 million of collateralized mortgage obligations were transferred to Level 2 from Level 3. The majority of securities available-for-sale are valued by external pricing services or dealer market participants and are classified in Level 2 of the fair value hierarchy. Both market and income valuation approaches are utilized. Quarterly, the Company evaluates the methodologies used by the external pricing services or dealer market participants to develop the fair values to determine whether the results of the valuations are representative of an exit price in the Company’s principal markets and an appropriate representation of fair value. The Company uses the following methods and significant assumptions to estimate fair value: ● Government-sponsored agency debt securities are primarily priced using available market information through processes such as benchmark spreads, market valuations of like securities, like securities groupings and matrix pricing. ● Other government-sponsored agency securities, mortgage-backed securities (“MBS”) and some of the actively traded real estate mortgage investment conduits and collateralized mortgage obligations are priced using available market information including benchmark yields, prepayment speeds, spreads, volatility of similar securities and trade date. ● State and political subdivisions are largely grouped by characteristics (e.g., geographical data and source of revenue in trade dissemination systems). Because some securities are not traded daily and due to other grouping limitations, active market quotes are often obtained using benchmarking for like securities. ● Auction rate securities are priced using market spreads, cash flows, prepayment speeds, and loss analytics. Therefore, the valuations of auction rate asset-backed securities are considered Level 2 valuations. ● Asset-backed collateralized loan obligations were priced using data from a pricing matrix supported by our bond accounting service provider and are therefore considered Level 2 valuations. ● Annually every security holding is priced by a pricing service independent of the regular and recurring pricing services used. The independent service provides a measurement to indicate if the price assigned by the regular service is within or outside of a reasonable range. Management reviews this report and applies judgment in adjusting calculations at year end related to securities pricing. ● Residential mortgage loans available for sale in the secondary market are carried at fair market value. The fair value of loans held-for-sale is determined using quoted secondary market prices. ● Lending related commitments to fund certain residential mortgage loans, e.g., residential mortgage loans with locked interest rates to be sold in the secondary market and forward commitments for the future delivery of mortgage loans to third party investors, as well as forward commitments for future delivery of MBS, are considered derivatives. Fair values are estimated based on observable changes in mortgage interest rates including prices for MBS from the date of the commitment and do not typically involve significant judgments by management. ● The fair value of mortgage servicing rights is based on a valuation model that calculates the present value of estimated net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income to derive the resultant value. The Company is able to compare the valuation model inputs, such as the discount rate, prepayment speeds, weighted average delinquency and foreclosure/bankruptcy rates to widely available published industry data for reasonableness. ● Interest rate swap positions, both assets and liabilities, are based on valuation pricing models using an income approach reflecting readily observable market parameters such as interest rate yield curves. ● The fair value of individually evaluated loans with specific allocations of the allowance for credit losses is essentially based on recent real estate appraisals or the fair value of the collateralized asset. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are made in the appraisal process by the appraisers to reflect differences between the available comparable sales and income data. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. ● Nonrecurring adjustments to certain commercial and residential real estate properties classified as other real estate owned (“OREO”) are measured at fair value, less costs to sell. Fair values are based on third party appraisals of the property, resulting in a Level 3 classification, or an executed pending sales contract. In cases where the carrying amount exceeds the fair value, less costs to sell, a valuation loss is recognized.

These assets consist of individually evaluated loans and OREO. For assets measured at fair value on a nonrecurring basis at September 30, 2024, and December 31, 2023, respectively, the following tables provide the level of valuation assumptions used to determine each valuation and the carrying value of the related assets: September 30, 2024 Level 1 Level 2 Level 3 Total Individually evaluated loans 1 $ - $ - $ 42,005 $ 42,005 Other real estate owned, net 2 - - 8,202 8,202 Total $ - $ - $ 50,207 $ 50,207 1 Represents carrying value and related write-downs of loans for which adjustments are substantially based on the appraised value of collateral for collateral-dependent loans, which had a carrying amount of $50.2 million and a valuation allowance of $8.2 million resulting in a decrease of specific allocations within the allowance for credit losses on loans of $2.9 million for the nine months ended September 30, 2024. 2 OREO is measured at fair value, less costs to sell, and had a net carrying amount of $8.2 million at September 30, 2024, which is made up of the outstanding balance of $8.3 million, net of a valuation allowance of $118,000 December 31, 2023 Level 1 Level 2 Level 3 Total Individually evaluated loans 1 $ - $ - $ 66,180 $ 66,180 Other real estate owned, net 2 - - 5,123 5,123 Total $ - $ - $ 71,303 $ 71,303 1 Represents carrying value and related write-downs of loans for which adjustments are substantially based on the appraised value of collateral for collateral-dependent loans, which had a carrying amount of $77.3 million and a valuation allowance of $11.1 million resulting in a decrease of specific allocations within the allowance for credit losses on loans of $6.5 million for the year December 31, 2023. 2 OREO is measured at fair value, less costs to sell, and had a net carrying amount of $5.1 million at December 31, 2023, which is made up of the outstanding balance of $5.2 million, net of a valuation allowance of $118,000 . The Company has estimated the fair values of these assets based primarily on Level 3 inputs. OREO and individually evaluated loans are generally valued using the fair value of collateral provided by third party appraisals. These valuations include assumptions related to cash flow projections, discount rates, and recent comparable sales. The numerical ranges of unobservable inputs for these valuation assumptions are not meaningful.

Fair Values of Financial Instruments	Note 12 – Fair Values of Financial Instruments The estimated fair values approximate carrying amount for all items except those described in the following table. Securities available-for-sale fair values are based upon market prices or dealer quotes, and if no such information is available, on the rate and term of the security. The carrying value of FHLBC stock approximates fair value as the stock is nonmarketable and can only be sold to the FHLBC or another member institution at par. At September 30, 2024, and December 31, 2023, the fair values of loans are estimated on an exit price basis incorporating discounts for credit, liquidity and marketability factors. The fair value of time deposits was estimated using discounted future cash flows at current rates offered for deposits of similar remaining maturities. The fair values of borrowings were estimated based on interest rates available to the Company for debt with similar terms and remaining maturities. The fair value of off-balance sheet volume was not considered material.

Derivatives, Hedging Activities and Financial Instruments with Off-Balance Sheet Risk	Note 13 – Derivatives, Hedging Activities and Financial Instruments with Off-Balance Sheet Risk Risk Management Objective of Using Derivatives The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s loan portfolio. Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. The aggregate fair value of the swaps is recorded in other assets or other liabilities with changes in fair value recorded in other comprehensive income, net of tax. The amount included in other comprehensive income would be reclassified to current earnings should all or a portion of the hedge no longer be considered effective. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income and subsequently reclassified into interest income or interest expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest income or expense as interest payments are received on the variable rate loan pools or paid on the Company’s fixed-rate borrowings. Interest rate swaps with notional amounts totaling $300.0 million as of September 30, 2024, and December 31, 2023, were designated as cash flow hedges of certain variable rate commercial and commercial real estate loan pools. Each of these hedges were executed to pay variable and receive fixed rate cash flows. Each of these hedges was determined to be effective during all periods presented and the Company expects the hedges to remain effective during the remaining terms of the swaps. An interest rate swap with a notional amount of $25.8 million as of September 30, 2024, and December 31, 2023, is designated as a cash flow hedge of junior subordinated debentures and was executed to pay fixed and receive variable rate cash flows. The hedge was determined to be effective during all periods presented and the Company expects the hedge to remain effective during the remaining terms of the swap. During the next twelve months, the Company estimates that an additional $2.0 million will be reclassified as an increase to interest income and an additional $327,000 will be reclassified as an increase to interest expense. Non-designated Hedges Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps and rate cap agreements with commercial banking customers to facilitate their respective risk management strategies. The notional amounts of interest rate swaps with its loan customers as of September 30, 2024, and December 31, 2023 were $120.5 million and $104.8 million, respectively. The notional amounts of interest rate cap agreements with its loan customers were $32.9 million as of September 30, 2024, and there were no interest rate cap agreements held at December 31, 2023. Those interest rate swaps and rate cap agreements are simultaneously hedged by offsetting derivatives that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate derivatives associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings. At September 30, 2024, and December 31, 2023, the Company had $3.6 million and $7.3 million of cash collateral pledged with two correspondent financial institutions, respectively. The Company held $2.6 million and $4.1 million of cash pledged from one correspondent financial institution to support the interest rate swap activity during the periods presented, respectively. No investment securities were required to be pledged to any correspondent financial institution during 2024 through September 30, 2024, or during 2023. The Company offsets derivative assets and liabilities that are subject to a master netting arrangement. The Company also grants mortgage loan interest rate lock commitments to borrowers, subject to normal loan underwriting standards. The interest rate risk associated with these loan interest rate lock commitments is managed with contracts for future deliveries of loans as well as selling forward mortgage-backed securities contracts. Loan interest rate lock 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 notional amount of these commitments at September 30, 2024, and December 31, 2023 was $18.8 million and $8.4 million, respectively. Commitments to originate residential mortgage loans held-for-sale and forward commitments to sell residential mortgage loans or forward MBS contracts are considered derivative instruments and changes in the fair value are recorded to mortgage banking revenue. Fair values are estimated based on observable changes in mortgage interest rates including mortgage-backed securities prices from the date of the commitment. The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the Consolidated Balance Sheets as of September 30, 2024, and December 31, 2023.

The gain recognized in AOCI on derivatives totaled $88,000 as of September 30, 2024, and the loss recognized in AOCI totaled $3.8 million as of September 30, 2023. The amount of the loss reclassified from AOCI to net interest income on the income statement was $4.8 million for the nine months ended September 30, 2024, and $3.9 million for the nine months ended September 30, 2023. Credit-risk-related Contingent Features For derivative transactions involving counterparties who are lending customers of the Company, the derivative credit exposure is managed through the normal credit review and monitoring process, which may include collateralization, financial covenants and/or financial guarantees of affiliated parties. Agreements with such customers require that losses associated with derivative transactions receive payment priority from any funds recovered should a customer default and ultimate disposition of collateral or guarantees occur. Credit exposure to broker/dealer counterparties is managed through agreements with each derivative counterparty that require collateralization of fair value gains owed by such counterparties. Some small degree of credit exposure exists due to timing differences between when a gain may occur and the subsequent point in time that collateral is delivered to secure that gain. This is monitored by the Company and procedures are in place to minimize this exposure. Such agreements also require the Company to collateralize counterparties in circumstances wherein the fair value of the derivatives result in loss to the Company. Other provisions of such agreements include the definition of certain events that may lead to the declaration of default and/or the early termination of the derivative transaction(s): ● If the Company either defaults or is capable of being declared in default on any of its indebtedness (exclusive of deposit obligations), then the Company could also be declared in default on its derivative obligations. ● If a merger occurs that materially changes the Company's creditworthiness in an adverse manner. ● If certain specified adverse regulatory actions occur, such as the issuance of a Cease and Desist Order, or citations for actions considered Unsafe and Unsound or that may lead to the termination of deposit insurance coverage by the FDIC. The Bank also issues letters of credit, which are conditional commitments that guarantee the performance of a customer to a third party. The credit risk involved and collateral obtained in issuing letters of credit are essentially the same as that involved in extending loan commitments to our customers. In addition to customer related commitments, the Company is responsible for letters of credit commitments that relate to properties held in OREO. The following table represents the Company’s contractual commitments due to letters of credit as of September 30, 2024, and December 31, 2023. The following table is a summary of letter of credit commitments: September 30, 2024 December 31, 2023 Fixed Variable Total Fixed Variable Total Letters of credit: Borrower: Financial standby $ 188 $ 16,240 $ 16,428 $ 173 $ 16,621 $ 16,794 Performance standby 552 10,784 11,336 562 13,689 14,251 740 27,024 27,764 735 30,310 31,045 Non-borrower: Performance standby - 67 67 - 67 67 Total letters of credit $ 740 $ 27,091 $ 27,831 $ 735 $ 30,377 $ 31,112 Unused loan commitments: $ 153,788 $ 623,748 $ 777,536 $ 140,305 $ 694,960 $ 835,265 As of September 30, 2024, the Company evaluated current market conditions, including any impacts related to market interest rate changes and unused line of credit utilization trends during the third quarter of 2024, and based on that analysis under the CECL methodology, the Company determined credit losses related to unfunded commitments totaled $2.5 million. The resultant increase in the ACL for unfunded commitments of $2,000 for the third quarter of 2024, compared to the second quarter of 2024, is primarily driven by adjustments to historical benchmark assumptions, such as the funding rates and the period used to forecast those rates within the ACL calculation. The Company will continue to assess the credit risk at least quarterly, and adjust the allowance for unfunded commitments, which is carried within other liabilities on our Consolidated Balance Sheets, as needed, with the appropriate offsetting entry to the provision for credit losses on our Consolidated Statements of Income.
