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 March 31, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. These interim consolidated financial statements 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, 2021. 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. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates” Note 1 – Summary of Significant Accounting Policies, Financial Instruments – Measurement of Credit Losses on Financial Instruments (Topic 326) Recent Accounting Pronouncements The following is a summary of recent accounting pronouncements that have impacted or could potentially affect the Company : ASU 2018-16, ASU 2020-04 and ASU 2021-01 - Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting. Reference Rate Reform The Company formed a LIBOR transition team in 2019, and has developed a project plan to assess the use of alternative indexes and to seek to ensure all financial instruments that reference LIBOR are identified, quantified, and researched for the LIBOR fallback language available or needed. The Company has completed the ISDA protocol adherence for LIBOR fallback language for all commercial swaps, has met with our commercial loan clients to also guide their swap fallback language adherence, and worked to revise all credit documents being issued by our Bank for new loans to ensure appropriate fallback language is included. We have discontinued the use of LIBOR as a reference rate for all consumer loans issued after July 31, 2021, and all commercial loans issued after December 31, 2021, with certain exceptions for those loans that were in the process of funding at the end of 2021. The Company’s systems have been updated to handle multiple SOFR-based indexes and we continue to meet regularly to plan for the transition of existing LIBOR exposures prior to the final LIBOR cessation date of June 30, 2023. ASU 2022-02 Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures The Company is currently reviewing ASU 2022-02 for the impact to TDR recognition, measurement and disclosures, and will assess any revisions needed for reporting purposes in the next few quarters. We anticipate adopting ASU 2022-02 as of January 1, 2023. 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, 2021. 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 first quarter of 2022, the Company had no changes to significant accounting policies or estimates. Subsequent Events On April 19, 2022, the Company’s Board of Directors declared a cash dividend of $0.05 per share payable on May 9, 2022, to stockholders of record as of April 29, 2022; dividends of $2.2 million are scheduled to be paid to stockholders on May 9, 2022.

Acquisition	Note 2 – Acquisition On December 1, 2021, the Company completed its acquisition of West Suburban Bancorp, Inc. (“West Suburban”), a bank holding company, and its wholly owned subsidiary, West Suburban Bank, based in Lombard, Illinois, with operations throughout our existing market footprint. This acquisition brought increased scale and new markets to the Company, and provided new product offerings and line of business opportunities. At closing, the Company acquired $2.94 billion of assets, $1.50 billion of loans, $1.07 billion of securities, and $2.69 billion of deposits, net of fair value adjustments. Under the terms of the merger agreement, each outstanding share of West Suburban common stock was exchanged for 42.413 shares of Company common stock, plus $271.15 of cash. This resulted in merger consideration of $295.2 million, based on the closing price of the Company’s common stock on the date of acquisition, which consisted of 15.7 million shares of the Company’s common stock and $100.7 million of cash. Goodwill of $67.7 million associated with the acquisition was recorded by the Company, which was the result of expected synergies, operational efficiencies and other factors. The acquisition of West Suburban was accounted for as a business combination. We recorded the estimate of fair value based on initial valuations available at December 1, 2021. The determination of estimated fair value required management to make assumptions related to discount rates, expected future cash flows, market conditions and other future events that are often subjective in nature and may require adjustments. Accordingly, these estimated fair values are considered preliminary as of March 31, 2022, and are subject to adjustment for up to one year after December 1, 2021. These adjustments may include: (i) changes in deferred tax assets or liabilities related to fair value estimates and changes in the expected realization of items considered to be net operating loss carryforwards due to tax calculations still in process, and (ii) changes in goodwill as a result of the net effect of any adjustments. No adjustments were identified during the quarter ended March 31, 2022. None of the $67.7 million of goodwill recorded is expected to be deductible for income tax purposes. The following table provides the preliminary purchase price allocation as of the December 1, 2021 closing date of the merger for the estimated fair value of the assets acquired and liabilities assumed, as recorded by the Company. West Suburban Acquisition Summary As of Date of Acquisition December 1, 2021 Assets Cash and due from banks $ 16,794 Interest bearing deposits with financial institutions 232,880 Securities available-for-sale and held-to maturity, at fair value 1,066,373 FHLBC stock 3,340 Loans, net of allowance for credit losses Day One PCD loan adjustment 1,502,118 Premises and equipment 47,456 Other real estate owned 5,552 Core deposit intangible 14,772 Deferred tax assets 2,093 Other assets 52,710 Total assets $ 2,944,088 Liabilities Noninterest bearing demand $ 409,141 Savings, NOW and money market 2,069,890 Time 215,205 Total deposits 2,694,236 Reserve for unfunded commitments 1,787 Other liabilities 20,629 Total liabilities 2,716,652 Cash consideration paid 100,679 Stock issued for acquisition 194,484 Total Liabilities Assumed and Cash and Stock Consideration Paid for Acquisition $ 3,011,815 Goodwill $ 67,727 Expenses related to the West Suburban acquisition totaled $5.6 million for the quarter ended March 31, 2022, and $13.2 million during the year ended December 31, 2021, and are reported within noninterest expense based on the line items impacted, which are primarily salaries and employee benefits, occupancy, furniture and equipment, computer and data processing, legal fees, and other expense in the Consolidated Statements of Income. Purchased loans and leases that reflect a more-than-insignificant deterioration of credit from origination are considered purchased credit deteriorated (“PCD”) loans. For PCD loans, the initial estimate of expected credit losses was recognized in the allowance for credit losses (“ACL”) on the date of acquisition using the same methodology as other loans and leases held-for-investment. The following table provides a summary of loans purchased as part of the West Suburban acquisition which were individually evaluated and determined to be PCD loans at acquisition. As of West Suburban Acquired PCD Loans December 1, 2021 Par value of acquired loans $ 108,241 Allowance for credit losses (12,075) Non-credit discount (1,723) Purchase price of PCD loans at acquisition $ 94,443 The following table presents the carrying amount of all acquired loans as of March 31, 2022 and December 21, 2021, including loans that, as of the acquisition date, had not experienced a more-than-insignificant deterioration in credit quality since origination (“non-PCD loans”): Acquired Loan Detail As of March 31, 2022 As of December 31, 2021 PCD Non-PCD Total PCD Non-PCD Total West Suburban acquired loans $ 88,601 $ 1,354,305 $ 1,442,906 $ 102,409 $ 1,418,752 $ 1,521,161 ABC Bank acquired loans 4,534 57,904 62,438 4,547 64,236 68,783 Talmer Bank acquired loans - 44,836 44,836 - 45,858 45,858 Total acquired loans net book value $ 93,135 $ 1,457,045 $ 1,550,180 $ 106,956 $ 1,528,846 $ 1,635,802 Accretion recorded on acquired loans year to date $ 400 $ 2,016 $ 2,416 $ 401 $ 565 $ 966

Securities	Note 3 – 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.

Under the FFEL, private lenders made federally guaranteed student loans to parents and students. While the program was modified several times before elimination in 2010, FFEL securities are generally guaranteed by the U.S Department of Education (“DOE”) at not less than 97% of the outstanding principal amount of the loans. The guarantee will reduce to 85% if the DOE receives reimbursement requests in excess of 5% of insured loans; reimbursement will drop to 75% if reimbursement requests exceed 9% of insured loans. In addition to the DOE guarantee, total added credit enhancement in the form of overcollateralization and/or subordination amounted to $20.3 million, or 9.29%, of outstanding principal. At March 31, 2022, the Company had no securities issued from any one originator, other than the U.S. Government and its agencies, which individually amounted to over 10% of the Company’s stockholders’ equity.

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. No credit losses were determined to be present as of March 31, 2022, as there was no credit quality deterioration noted. Therefore, no provision for credit losses on securities was recognized for the first quarter of 2022. There were no securities sold for the three months ended March 31, 2022 or March 31, 2021. As of March 31, 2022, securities valued at $478.2 million were pledged to secure deposits and borrowings, and for other purposes, a decrease from $501.3 million of securities pledged at year-end 2021.

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 assure 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 72.7% and 71.6% of the portfolio at March 31, 2022, and December 31, 2021, respectively, and include a mix of owner and non-owner occupied, residential, construction and multifamily loans.

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 March 31, 2022 were as follows: Revolving Loans Converted Revolving To Term 2022 2021 2020 2019 2018 Prior Loans Loans Total Commercial Pass $ 39,944 $ 112,254 $ 42,384 $ 22,145 $ 15,024 $ 8,914 $ 420,642 $ -

Troubled debt restructurings (“TDRs”) are loans for which the contractual terms have been modified and both of these conditions exist: (1) there is a concession to the borrower and (2) the borrower is experiencing financial difficulties. Loans are restructured on a case-by-case basis during the loan collection process with modifications generally initiated at the request of the borrower. These modifications may include reduction in interest rates, extension of term, deferrals of principal, and other modifications. The Bank participates in the U.S. Department of the Treasury’s (the “Treasury”) Home Affordable Modification Program (“HAMP”) which gives qualifying homeowners an opportunity to refinance into more affordable monthly payments. Additionally, in accordance with interagency guidance, short-term deferrals granted due to the COVID-19 pandemic were not considered TDRs, if modified prior to January 1, 2022, unless the borrower was experiencing financial difficulty prior to the pandemic. The specific allocation of the allowance for credit losses for TDRs is determined by calculating the present value of the TDR cash flows by discounting the original payment less an assumption for probability of default at the original note’s issue rate, and adding this amount to the present value of collateral less selling costs. If the resulting amount is less than the recorded book value, the Bank either establishes a valuation allowance (i.e., specific reserve) as a component of the allowance for credit losses or charges off the impaired balance if it determines that such amount is a confirmed loss. This method is used consistently for all segments of the portfolio. The allowance for credit losses also includes an allowance based on a loss migration analysis for each loan category on loans and leases that are not individually evaluated for specific impairment. All loans charged-off, including TDRs charged-off, are factored into this calculation by portfolio segment. There was one TDR loan modification of $1.1 million for the three months ended March 31, 2022, and no TDR activity for the three months ended March 31, 2021. TDRs are classified as being in default on a case-by-case basis when they fail to be in compliance with the modified terms. There was no TDR default activity for the periods ended March 31, 2022, and March 31, 2021, for loans that were restructured within the prior 12 month period.

Junior subordinated debentures are discussed in more detail in Note 8: March 31, 2022 December 31, 2021 Securities sold under repurchase agreements $ 33,521 $ 50,337 Junior subordinated debentures 25,773 25,773 Subordinated debentures 59,233 59,212 Senior notes 44,506 44,480 Notes payable and other borrowings 17,992 19,074 Total borrowings $ 181,025 $ 198,876 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 $33.5 million at March 31, 2022, and $50.3 million at December 31, 2021. The fair value of the pledged collateral was $107.3 million at March 31, 2022, and $113.0 million at December 31, 2021. At March 31, 2022, 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 March 31, 2022, and December 31, 2021, the Bank had no short-term advances outstanding under the FHLBC. The Bank assumed $23.4 million of long-term FHLBC advances with our ABC Bank acquisition in 2018. At March 31, 2022, one advance remains in long-term status, with a total outstanding balance of $6.0 million, at a 2.83% interest rate, and is scheduled to mature on February 2, 2026. FHLB stock held as of March 31, 2022 was valued at $7.1 million, and any potential FHLBC advances were collateralized by loans with a principal balance of $545.0 million, which carried a FHLBC-calculated combined collateral value of $396.9 million. The Company had excess collateral of $315.9 million available to secure borrowings at March 31, 2022. The Company also had $44.5 million of senior notes outstanding, net of deferred issuance costs, as of March 31, 2022 and December 31, 2021. The senior notes were issued in December 2016 with a ten year maturity, and terms include interest payable semiannually at 5.75% for five years . Beginning December 31, 2021, the senior debt began to pay interest at a floating rate, with interest payable quarterly at three month LIBOR plus 385 basis points. The notes are redeemable, in whole or in part, at the option of the Company, beginning with the interest payment date on December 31, 2021, and on any floating rate interest payment date thereafter, at a redemption price equal to 100% of the principal amount of the notes plus accrued and unpaid interest. As of March 31, 2022, and December 31, 2021, unamortized debt issuance costs related to the senior notes were $494,000 and $520,000 , respectively, and are included as a reduction of the balance of the senior notes on the Consolidated Balance Sheet. These deferred issuance costs will be amortized to interest expense over the ten year term of the notes and are included in the Consolidated Statements of Income. On February 24, 2020, the Company originated a $20.0 million term note, of which $12.0 million is outstanding as of March 31, 2022, with a correspondent bank. The term note was issued for a three year term at one-month LIBOR plus 175 basis points, requires principal and interest payments quarterly, and the balance of this note is included within Notes Payable and Other Borrowings on the Consolidated Balance Sheet. 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. On April 6, 2021, we sold and 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 Notes were offered and sold to eligible purchasers in a private offering in reliance on the exemption from the registration requirements of Section 4(a)(2) of the Securities Act of 1933, as amended and the provisions of Regulation D promulgated thereunder. The Company intends to use the net proceeds from the offering for general corporate purposes, which may include, without limitation, the redemption of existing senior debt, common stock repurchases and strategic acquisitions. 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 SOFR (as defined in the Note) plus 273 basis points, payable quarterly in arrears.

Junior Subordinated Debentures	Note 8 – 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 LIBOR . Upon conversion to a floating rate, a cash flow hedge was initiated which resulted in the total interest rate paid on the debt of 4.41% for the quarters ended March 31, 2022 and March 31, 2021. The Company issued a new $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 Sheet, and the related interest expense for each issuance is included in the Consolidated Statements of Income. As of March 31, 2022, and December 31, 2021, the remaining unamortized debt issuance costs related to the junior subordinated debentures were $1,000 and are included as a reduction to the balance of the junior subordinated debentures on the Consolidated Balance Sheet. 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 9 – 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 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 March 31, 2022, 1,144,926 shares remained available for issuance under the 2019 Plan Under the 2019 Plan, unless otherwise provided in an award agreement, upon the occurrence of a change in control, all stock options and SARs 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 units 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 Generally, restricted stock and restricted stock units granted under the Plans vest three years from the grant date, but the Compensation Committee of the Company’s Board of Directors has discretionary authority to change some terms including the amount of time until the vest date. There were 251,055 and 217,964 restricted stock units issued under the 2019 Plan during the three months ended March 31, 2022 and March 31, 2021, 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 Plan was $795,000 in the first three months of 2022 and $125,000 for the first three months of 2021. A summary of changes in the Company’s unvested restricted awards for the three months ended March 31, 2022, is as follows: March 31, 2022 Weighted Restricted Average Stock Shares Grant Date and Units Fair Value Unvested at January 1 540,306 $ 12.04 Granted 251,055 14.28 Vested - - Forfeited - - Unvested at March 31 791,361 $ 12.75 Total unrecognized compensation cost of restricted awards was $5.8 million as of March 31, 2022, which is expected to be recognized over a weighted-average period of 1.1 years.

Regulatory & Capital Matters
Regulatory & Capital Matters	Note 11 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 March 31, 2022, the Bank exceeded those thresholds. At March 31, 2022, the Bank’s Tier 1 capital leverage ratio was 8.61%, a decrease of 97 basis points from December 31, 2021, but is above the 8.00% objective. The Bank’s total capital ratio was 13.83%, an increase of 37 basis points from December 31, 2021, 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 March 31, 2022, and December 31, 2021. In July 2013, the U.S. federal banking authorities issued final rules (the “Basel III Rules”) establishing more stringent regulatory capital requirements for U.S. banking institutions, which went into effect on January 1, 2015. 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, 2021, under the heading “Supervision and Regulation.” At March 31, 2022 and December 31, 2021, 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 March 31, 2022 Common equity tier 1 capital to risk weighted assets Consolidated $ 404,444 9.73 % $ 290,967 7.00 % N/A N/A Old Second Bank 528,655 12.74 290,470 7.00 $ 269,722 6.50 % Total capital to risk weighted assets Consolidated 533,984 12.85 436,329 10.50 N/A N/A Old Second Bank 573,949 13.83 435,753 10.50 415,003 10.00 Tier 1 capital to risk weighted assets Consolidated 429,444 10.33 353,366 8.50 N/A N/A Old Second Bank 528,655 12.74 352,713 8.50 331,965 8.00 Tier 1 capital to average assets Consolidated 429,444 7.00 245,397 4.00 N/A N/A Old Second Bank 528,655 8.61 245,600 4.00 307,001 5.00 December 31, 2021 Common equity tier 1 capital to risk weighted assets Consolidated $ 394,421 9.46 % $ 291,855 7.00 % N/A N/A Old Second Bank 514,992 12.41 290,487 7.00 $ 269,738 6.50 % Total capital to risk weighted assets Consolidated 522,932 12.55 437,513 10.50 N/A N/A Old Second Bank 558,503 13.46 435,682 10.50 414,935 10.00 Tier 1 capital to risk weighted assets Consolidated 419,421 10.06 354,382 8.50 N/A N/A Old Second Bank 514,992 12.41 352,734 8.50 331,985 8.00 Tier 1 capital to average assets Consolidated 419,421 7.81 214,812 4.00 N/A N/A Old Second Bank 514,992 9.58 215,028 4.00 268,785 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 CECL 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 March 31, 2022, the capital measures of the Company exclude $2.9 million, 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. Pursuant to the Basel III rules that came into effect January 1, 2015, and were fully phased in as of January 1, 2019, the Bank must keep a capital conservation buffer of 2.50% above the new 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
Fair Value Measurements	Note 12 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. Transfers between levels are deemed to have occurred at the end of the reporting period. At March 31, 2022 and 2021, there were no transfers between levels. 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, 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 impaired 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 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, an impairment loss is recognized. Assets and Liabilities Measured at Fair Value on a Recurring Basis The tables below present the balance of assets and liabilities at March 31, 2022, and December 31, 2021, respectively, measured by the Company at fair value on a recurring basis: March 31, 2022 Level 1 Level 2 Level 3 Total Assets: Securities available-for-sale U.S. Treasury $ 220,563 $ - $ - $ 220,563 U.S. government agencies - 59,036 - 59,036 U.S. government agencies mortgage-backed - 153,148 - 153,148 States and political subdivisions - 222,575 13,833 236,408 Corporate bonds - 9,683 - 9,683 Collateralized mortgage obligations - 696,513 - 696,513 Asset-backed securities - 274,941 - 274,941 Collateralized loan obligations - 166,158 - 166,158 Loans held-for-sale - 8,075 - 8,075 Mortgage servicing rights - - 10,376 10,376 Interest rate swap agreements - 952 - 952 Mortgage banking derivatives - 930 - 930 Total $ 220,563 $ 1,592,011 $ 24,209 $ 1,836,783 Liabilities: Interest rate swap agreements, including risk participation agreements $ - $ 3,663 $ - $ 3,663 Total $ - $ 3,663 $ - $ 3,663 December 31, 2021 Level 1 Level 2 Level 3 Total Assets: Securities available-for-sale U.S. Treasury $ 202,339 $ - $ - $ 202,339 U.S. government agencies - 61,888 - 61,888 U.S. government agencies mortgage-backed - 172,302 - 172,302 States and political subdivisions - 242,373 14,092 256,465 Corporate bonds - 9,887 - 9,887 Collateralized mortgage obligations - 672,967 - 672,967 Asset-backed securities - 236,877 - 236,877 Collateralized loan obligations - 79,763 - 79,763 Loans held-for-sale - 4,737 - 4,737 Mortgage servicing rights - - 7,097 7,097 Interest rate swap agreements - 3,494 - 3,494 Mortgage banking derivatives - 508 - 508 Total $ 202,339 $ 1,484,796 $ 21,189 $ 1,708,324 Liabilities: Interest rate swap agreements, including risk participation agreements $ - $ 6,809 $ - $ 6,809 Total $ - $ 6,809 $ - $ 6,809 The changes in Level 3 assets and liabilities measured at fair value on a recurring basis are as follows: Three Months Ended March 31, 2022 Securities available-for-sale States and Mortgage Political Servicing Subdivisions Rights Beginning balance January 1, 2022 $ 14,092 $ 7,097 Total gains or losses Included in earnings (33) 3,228 Included in other comprehensive income (938) - Purchases, issuances, sales, and settlements Purchases 1,076 - Issuances - 301 Settlements (364) (250) Ending balance March 31, 2022 $ 13,833 $ 10,376 Three Months Ended March 31, 2021 Securities available-for-sale States and Mortgage Political Servicing Subdivisions Rights Beginning balance January 1, 2021 $ 4,319 $ 4,224 Total gains or losses Included in earnings (3) 1,485 Included in other comprehensive income 299 - Purchases, issuances, sales, and settlements Purchases 58 - Issuances - 552 Settlements (32) (372) Ending balance March 31, 2021 $ 4,641 $ 5,889 The following table and commentary presents quantitative and qualitative information about Level 3 fair value measurements as of March 31, 2022: Weighted Measured at fair value Significant Unobservable Average on a recurring basis: Fair Value Valuation Methodology Inputs Range of Input of Inputs Mortgage servicing rights $ 10,376 Discounted Cash Flow Discount Rate 9.0 - 11.0% 9.0 % Prepayment Speed 5.7 - 28.9% 6.2 % The following table and commentary presents quantitative and qualitative information about Level 3 fair value measurements as of December 31, 2021: Weighted Measured at fair value Significant Unobservable Average on a recurring basis: Fair Value Valuation Methodology Inputs Range of Input of Inputs Mortgage servicing rights $ 7,097 Discounted Cash Flow Discount Rate 11.0 - 15.0% 11.0 % Prepayment Speed 0.0 - 36.6% 11.9 % In addition to the above, Level 3 fair value measurement included $13.8 million for state and political subdivisions representing various local municipality securities at March 31, 2022. These securities were classified as securities available-for-sale, and were valued using a discount based on market spreads of similar assets, but the liquidity premium was an unobservable input. The state and political subdivisions securities balance in Level 3 fair value at March 31, 2021, was $4.6 million. These securities were classified as securities available-for-sale, and were valued using a discount based on market spreads of similar assets, but the liquidity premium was an unobservable input. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis: The Company may be required, from time to time, to measure certain other assets at fair value on a nonrecurring basis in accordance with GAAP. These assets consist of individually evaluated (formerly, impaired) loans and OREO. For assets measured at fair value on a nonrecurring basis at March 31, 2022, and December 31, 2021, respectively, the following tables provide the level of valuation assumptions used to determine each valuation and the carrying value of the related assets: March 31, 2022 Level 1 Level 2 Level 3 Total Individually evaluated loans 1 $ - $ - $ 21,990 $ 21,990 Other real estate owned, net 2 - - 2,374 2,374 Total $ - $ - $ 24,364 $ 24,364 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 $33.6 million and a valuation allowance of $11.6 million resulting in an increase of specific allocations within the allowance for credit losses on loans of $6.2 million for the three months ended March 31, 2022. 2 OREO is measured at fair value, less costs to sell, and had a net carrying amount of $2.4 million at March 31, 2022, which is made up of the outstanding balance of $3.7 million, net of a purchase accounting adjustment of $131,000 and a valuation allowance of $1.2 million. December 31, 2021 Level 1 Level 2 Level 3 Total Individually evaluated loans 1 $ - $ - $ 13,138 $ 13,138 Other real estate owned, net 2 - - 2,356 2,356 Total $ - $ - $ 15,494 $ 15,494 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 $18.5 million and a valuation allowance of $5.4 million resulting in an increase of specific allocations within the allowance for credit losses on loans of $2.7 million for the year December 31, 2021. 2 OREO is measured at fair value, less costs to sell, and had a net carrying amount of $2.4 million at December 31, 2021, which is made up of the outstanding balance of $3.7 million , net of a purchase accounting adjustment of $131,000 and a valuation allowance of $1.2 million. The Company has estimated the fair values of these assets based primarily on Level 3 inputs. OREO and impaired 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
Fair Values of Financial Instruments	Note 13 – 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. FHLBC stock is carried at cost and considered a Level 2 fair value. March 31, 2022 and December 31, 2021, the fair values of loans and leases are estimated on an exit price basis incorporating discounts for credit, liquidity and marketability factors. The fair value of time deposits is 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 is not considered material.

Derivatives, Hedging Activities and Financial Instruments with Off-Balance Sheet Risk
Derivatives, Hedging Activities and Financial Instruments with Off-Balance Sheet Risk	Note 14 – 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 expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. In December of 2019, the Company also executed a loan pool hedge of $50 million to convert variable rate loans to a fixed rate index for a five year term. 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/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 expense as interest payments are received on the Company’s variable-rate borrowings. During the next twelve months, the Company estimates that an additional $178,000 will be reclassified as an increase to interest income and an additional $162,000 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 with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps 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 with financial counterparties are recognized directly in earnings. 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. 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. Disclosure of Fair Values of Derivative Instruments on the Balance Sheet The Company entered into a forward starting interest rate swap on August 18, 2015, with an effective date of June 15, 2017. This transaction had a notional amount totaling $25.8 million as of March 31, 2022, was designated as a cash flow hedge of certain junior subordinated debentures and was determined to be fully effective during the period presented. As such, no amount of ineffectiveness has been included in net income. Therefore, the aggregate fair value of the swap is recorded in 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. The Company expects the hedge to remain fully effective during the remaining term of the swap. The Bank will pay the counterparty a fixed rate and receive a floating rate based on three month LIBOR. The trust preferred securities In December 2019, the Company also executed a loan pool hedge of $50.0 million to convert variable rate loans to a fixed rate index for a five year term. This transaction falls under hedge accounting standards and is paired against a pool of the Bank’s LIBOR-based loans. Overall, the new swap only bolsters income in down rate scenarios by a modest degree. We consider the current level of interest rate risk to be moderate but intend to continue looking for market opportunities to hedge further. The Bank also has interest rate derivative positions to assist with risk management that are not designated as hedging instruments. These derivative positions relate to transactions in which the Bank enters an interest rate swap with a client while at the same time entering into an offsetting interest rate swap with another financial institution. The Bank held no cash collateral and $180,000 of cash collateral related to one correspondent financial institution to cover the loan pool hedge mark to market valuation at March 31, 2022, and December 31, 2021, respectively. The Bank had $18.5 million and $17.2 million of cash collateral held by one correspondent financial institution to support interest rate swap activity and no investment securities were required to be pledged to any correspondent financial institution at March 31, 2022 and December 31, 2021, respectively. At March 31, 2022, the notional amount of non-hedging interest rate swaps was $150.7 million with a weighted average maturity of 5.9 years. At December 31, 2021, the notional amount of non-hedging interest rate swaps was $165.0 million with a weighted average maturity of 3.9 years. The Bank offsets derivative assets and liabilities that are subject to a master netting arrangement. The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the Balance Sheet as of March 31, 2022 and December 31, 2021.

The loss recognized in AOCI on derivatives totaled $1.9 million as of March 31, 2022, and $705,000 as of March 31, 2021. The amount of the gain reclassified from AOCI to interest income or interest expense on the income statement totaled $16,000 and $12,000 for the three months ended March 31, 2022, and March 31, 2021, respectively. 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 March 31, 2022, and December 31, 2021. The following table is a summary of letter of credit commitments: March 31, 2022 December 31, 2021 Fixed Variable Total Fixed Variable Total Letters of credit: Borrower: Financial standby $ 384 $ 19,416 $ 19,800 $ 384 $ 17,474 $ 17,858 Commercial standby - - - - - - Performance standby 308 15,683 15,991 456 14,907 15,363 692 35,099 35,791 840 32,381 33,221 Non-borrower: Performance standby - 67 67 - 67 67 Total letters of credit $ 692 $ 35,166 $ 35,858 $ 840 $ 32,448 $ 33,288 Unused loan commitments: $ 107,085 $ 910,602 $ 1,017,687 $ 84,225 $ 895,665 $ 979,890 As of March 31, 2022, the Company evaluated current market conditions, including any impacts related to COVID-19, market interest rate changes, and unused line of credit utilization trends during the first quarter of 2022, and based on that analysis under the CECL methodology, the Company determined credit losses related to unfunded commitments totaled $4.2 million, excluding a $1.5 million purchase accounting adjustment on unfunded commitments recorded from our West Suburban acquisition, which is being accreted to interest income over the estimated life of the unused commitments. The resultant decrease in the ACL for unfunded commitments of $320,000 for the first quarter of 2022, compared to the prior quarter end, is primarily related to a decrease in the commercial unfunded commitments funding rate assumptions based on our analysis of the last 12 months of utilization. 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 Sheet, as needed, with the appropriate offsetting entry to the provision for credit losses on our Consolidated Statements of Income.

Recent Accounting Pronouncements	Recent Accounting Pronouncements The following is a summary of recent accounting pronouncements that have impacted or could potentially affect the Company : ASU 2018-16, ASU 2020-04 and ASU 2021-01 - Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting. Reference Rate Reform The Company formed a LIBOR transition team in 2019, and has developed a project plan to assess the use of alternative indexes and to seek to ensure all financial instruments that reference LIBOR are identified, quantified, and researched for the LIBOR fallback language available or needed. The Company has completed the ISDA protocol adherence for LIBOR fallback language for all commercial swaps, has met with our commercial loan clients to also guide their swap fallback language adherence, and worked to revise all credit documents being issued by our Bank for new loans to ensure appropriate fallback language is included. We have discontinued the use of LIBOR as a reference rate for all consumer loans issued after July 31, 2021, and all commercial loans issued after December 31, 2021, with certain exceptions for those loans that were in the process of funding at the end of 2021. The Company’s systems have been updated to handle multiple SOFR-based indexes and we continue to meet regularly to plan for the transition of existing LIBOR exposures prior to the final LIBOR cessation date of June 30, 2023. ASU 2022-02 Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures The Company is currently reviewing ASU 2022-02 for the impact to TDR recognition, measurement and disclosures, and will assess any revisions needed for reporting purposes in the next few quarters. We anticipate adopting ASU 2022-02 as of January 1, 2023.
