CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This report and other publicly available documents of the Company contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act, including with respect to management’s expectations regarding future plans, strategies and financial performance, including regulatory developments, industry and economic trends, and other matters. Forward-looking statements, which may be based upon beliefs, expectations and assumptions of the Company's management and on information currently available to management, can be identified by the inclusion of such qualifications as “expects,” “intends,” “believes,” “may,” “will,” “would,” “could,” “should,” “plan,” “anticipate,” “estimate,” “possible,” “likely” or other indications that the particular statements are not historical facts and refer to future periods. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and may be outside of the Company’s control. Actual events and results may differ materially from those described in such forward-looking statements due to numerous factors, including:

● our ability to execute our growth strategy;

● the continuing impact of COVID-19 and its variants on our business, including the impact of the actions taken by governmental authorities to try and contain the virus or address the impact of the virus on the United States economy, and the resulting effect of these items on our operations, liquidity and capital position, and on the financial condition of our borrowers and other customers;

● negative economic conditions that adversely affect the economy, real estate values, the job market and other factors nationally and in our market area, in each case that may affect our liquidity and the performance of our loan portfolio;

● the possibility that our previously announced merger with West Suburban does not close when expected or at all because required regulatory, stockholder or other approvals and other conditions to closing are not received or satisfied on a timely basis or at all;

● the occurrence of any event, change or other circumstances that could give rise to the right of the Company, West Suburban or both to terminate the Merger Agreement;

● the possibility that the anticipated benefits of the proposed merger with West Suburban, including anticipated cost savings and strategic gains, are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy, competitive factors in the areas where the Company and West Suburban do business, or as a result of other unexpected factors or events;

● the impact of purchase accounting with respect to the proposed merger with West Suburban, or any change in the assumptions used regarding the assets purchased and liabilities assumed to determine their fair value;

● diversion of management’s attention from ongoing business operations and opportunities as a result of the proposed merger with West Suburban;

● potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the proposed merger with West Suburban;

● the outcome of any legal proceedings that may be instituted against the Company or West Suburban as a result of the proposed merger with West Suburban;

● the integration of the businesses and operations of the Company and West Suburban, which may take longer than anticipated or be more costly than anticipated or have unanticipated adverse results relating to the Company’s and West Suburban’s existing businesses;

● the financial success and viability of the borrowers of our commercial loans;

● changes in U.S. monetary policy, the level and volatility of interest rates, the capital markets and other market conditions that may affect, among other things, our liquidity and the value of our assets and liabilities;

● the transition away from LIBOR to an alternative reference rate;

● competitive pressures from other financial service businesses and from nontraditional financial technology (“FinTech”) companies;

● any negative perception of our reputation or financial strength;

● our ability to raise additional capital on acceptable terms when needed;

● our ability to raise cost-effective funding to support business plans when needed:

● our ability to use technology to provide products and services that will satisfy customer demands and create efficiencies in operations;

● adverse effects on our information technology systems resulting from system failures, human error or cyberattacks;

● adverse effects of failures by our vendors to provide agreed upon services in the manner and at the cost agreed, particularly our information technology vendors and those vendors performing a service on the Company’s behalf;

● the impact of any claims or legal actions, including any effect on our reputation;

● losses incurred in connection with repurchases and indemnification payments related to mortgages;

● the soundness of other financial institutions and other counter-party risk;

● changes in accounting standards, rules and interpretations and the related impact on our financial statements, including assumptions surrounding the ongoing impact of CECL, which are subject to change based on a number of factors including changes in our macroeconomic forecasts, credit quality, loan composition and other factors;

● our ability to receive dividends from our subsidiaries;

● a decrease in our regulatory capital ratios;

● adverse federal or state tax assessments, or changes in tax laws or policies;

3

Table of Contents

● risks associated with actual or potential litigation or investigations by customers, regulatory agencies or others;

● legislative or regulatory changes, particularly changes in regulation of financial services companies;

● increased costs of compliance, heightened regulatory capital requirements and other risks associated with changes in regulation and the current regulatory environment, including changes as a result of the new presidential administration and Democratic control of Congress;

● negative changes in our capital position;

● the adverse effects of events beyond our control that may have a destabilizing effect on financial markets and the economy, such as epidemics and pandemics (including COVID-19), war or terrorist activities, essential utility outages, deterioration in the global economy, instability in the credit markets, disruptions in our customers’ supply chains or disruption in transportation;

● changes in trade policy and any related tariffs; and

● each of the factors and risks under the heading “Risk Factors” in our 2020 Annual Report on Form 10-K, in this Form 10-Q, and in subsequent filings we make with the SEC .

We caution readers that the foregoing list of factors is not exclusive, is not necessarily in order of importance and readers should not place undue reliance on any forward-looking statements. Because the Company’s ability to predict results or the actual effect of future plans or strategies is inherently uncertain, there can be no assurances that future actual results will correspond to any forward-looking statements and you should not rely on any forward-looking statements. Additionally, all statements in this Form 10-Q, including forward-looking statements, speak only as of the date they are made, and the Company undertakes no obligation to update any statement in light of new information or future events, except as required by applicable law.

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 June 30, 2021, are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. 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, 2020. 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

In June 2016, the Financial Standards Board, or FASB, issued Accounting Standards Update (ASU) No. 2016-13, “ Financial Instruments – Measurement of Credit Losses on Financial Instruments (Topic 326) ,” also known as Current Expected Credit Losses, or CECL. ASU 2016-13 was issued to provide financial statement users with more useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date to enhance the decision making process. The new methodology reflects expected credit losses based on relevant vintage historical information, supported by reasonable forecasts of projected loss given defaults, which will affect the collectability of the reported amounts. This new methodology also requires available-for-sale debt securities to have a credit loss recorded through an allowance rather than write-downs through an other than temporary impairment analysis. In addition, an allowance must be established for the credit risk related to unfunded commitments. ASU 2016-13 is effective for financial statements issued for fiscal years beginning after December 15, 2019, and was adopted as of January 1, 2020, by the Company. See “ Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies ” and Note 1 – Summary of Significant Accounting Policies , both found in our Annual Report on Form 10-K for the year ended December 31, 2020 for further discussion of our Allowance for Credit Losses methodology and assessment as a critical accounting policy.

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, 2020. 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 second quarter of 2021, the Company had no changes to significant accounting policies.

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.

Federal Home Loan Bank of Chicago (“FHLBC”) and Federal Reserve Bank of Chicago (“FRBC”) stock are considered nonmarketable equity investments. FHLBC stock was recorded at $ 3.7 million at June 30, 2021, and December 31, 2020. FRBC stock was recorded at $ 6.2 million at June 30, 2021, and December 31, 2020.

The following tables summarize the amortized cost and fair value of the securities portfolio at June 30, 2021, and December 31, 2020, and the corresponding amounts of gross unrealized gains and losses:

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 $ 10.8 million, or 9.76 % of outstanding principal.

Each quarter we perform an analysis to determine if any of the unrealized losses on securities available-for-sale are comprised of credit losses as compared to unrealized losses due to market interest rate adjustments. 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 June 30, 2021, as there was no credit quality deterioration noted. Therefore, no provision for credit losses on securities was recognized for the second quarter of 2021.

The following table presents proceeds from sale and net realized gains (losses) on securities available-for-sale for the three and six months ended June 30, 2021 and 2020:

1 Includes $ 70.2 million and $ 74.1 million of Paycheck Protection Program (“PPP”) loans at June 30, 2021 and December 31, 2020, respectively.

2 The “Other” segment includes consumer and overdrafts in this table and in subsequent tables within Note 3 - Loans and Allowance for Credit Losses on Loans.

3 Excludes accrued interest receivable of $ 6.5 million and $ 7.0 million at June 30, 2021 and December 31, 2020, respectively, that is recorded in other assets on the consolidated balance sheet.

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 73.2 % and 72.5 % of the portfolio at June 30, 2021, and December 31, 2020, 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. Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan at some future date.

Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. The substandard credit quality indicator includes both potential problem loans that are currently performing and nonperforming loans.

Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

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 June 30, 2021, were as follows:

The Company had $ 632,000 and $ 546,000 in residential real estate loans in the process of foreclosure as of June 30, 2021, and December 31, 2020, respectively.

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 are not considered TDRs 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 were no TDR activity for the three and six months ended June 30, 2021.

TDRs that were modified during the period are as follows:

TDR Modifications TDR Modifications
Three Months Ended June 30, 2020 Six Months Ended June 30, 2020
# of Pre-modification Post-modification # of Pre-modification Post-modification

HAMP 1 2 256 253 2 256 253
Total 2 $ 256 $ 253 2 $ 256 $ 253

1 HAMP: Home Affordable Modification Program

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 June 30, 2021, and June 30, 2020, for loans that were restructured within the prior 12 month period.

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 $ 68.6 million at June 30, 2021, and $ 67.0 million at December 31, 2020. The fair value of the pledged collateral was $ 114.8 million at June 30, 2021, and $ 94.4 million at December 31, 2020. At June 30, 2021, 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 June 30, 2021, and December 31, 2020 the Bank had no short-term advances outstanding under the FHLBC. The Bank also assumed $ 23.4 million of long-term FHLBC advances with the ABC Bank acquisition in 2018. At June 30, 2021, one advance remains in long-term status, with a total outstanding balance of $ 6.2 million, at a 2.83 % interest rate, and is scheduled to mature on February 2, 2026. FHLBC stock held at June 30, 2021 was valued at $ 3.7 million, and any potential FHLBC advances were collateralized by loans with a principal balance of $ 580.0 million, which carried a FHLBC-calculated combined collateral value of $ 420.9 million. The Company had excess collateral of $ 288.5 million available to secure borrowings at June 30, 2021.

The Company also had $ 44.4 million of senior notes outstanding, net of deferred issuance costs, as of June 30, 2021 and December 31, 2020. 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 2021, the senior debt will 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 June 30, 2021, and December 31, 2020, unamortized debt issuance costs related to the senior notes were $ 572,000 and $ 625,000 , 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 $ 15.0 million is outstanding as of June 30, 2021, with a correspondent bank related to the Company’s redemption of the 7.80 % cumulative trust preferred securities issued by Old Second Capital Trust I and related junior subordinated debentures. See the discussion in Note 7 – Junior Subordinated Debentures . 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 $ 20.0 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 will 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.

Note 7 – Junior Subordinated Debentures

On March 2, 2020, the Company redeemed the 7.80 % cumulative trust preferred securities issued by Old Second Capital Trust I (“OSBCP”) and related junior subordinated debentures, which totaled $ 32.6 million. These debentures were originally issued in 2003 for a term of 30 years at 7.80 % , and subject to regulatory approval, were able to be called in whole or in part by the Company after June 30, 2008. The Company received regulatory approval to redeem the debentures in early 2020, and notified OSBCP stockholders of the redemption in late January 2020. Cash disbursed for the redemption, including accrued interest on the debentures, totaled $ 33.0 million, or $ 10.13 per OSBCP share. The OSBCP redemption was funded by cash on hand and the $ 20 million term note discussed in Note 6 – Borrowings . Upon redemption of the junior subordinated debentures related to OSBCP in March 2020, the Company recognized the remaining unamortized debt issuance costs of $ 635,000 .

The Company issued $ 25.0 million of cumulative trust preferred securities through a private placement completed by another unconsolidated subsidiary, Old Second Capital Trust II, in April 2007. These trust preferred securities also mature in 30 years , but subject to the aforementioned 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 float at 150 basis points over three-month LIBOR thereafter. 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 quarter ended June 30, 2021, compared to the rate paid for the quarter ended June 30, 2020, of 4.42 % . 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 June 30, 2021, and December 31, 2020, 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.

Note 8 – Equity Compensation Plans

The Company’s 2019 Equity Incentive Plan, which authorized 600,000 shares for issuance under the plan, was approved at the May 2019 annual stockholders’ meeting. Following approval of such plan, no further awards will be granted under any other prior Company equity compensation plan. At the May 2021 annual stockholders’ meeting, the Company obtained stockholder approval to amend and restate the 2019 Equity Incentive Plan 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 (the “2019 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 June 30, 2021, 1,420,020 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. 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.

Awards of restricted stock under the Plans 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 Plans 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 222,964 and 137,944 restricted stock units issued under the 2019 Plan during the six months ended June 30, 2021 and June 30, 2020, 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 $ 644,000 in the first six months of 2021 and $ 1.3 million for the first six months of 2020.

A summary of changes in the Company’s unvested restricted awards for the six months ended June 30, 2021, is as follows:

June 30, 2021
Weighted
Restricted Average
Stock Shares Grant Date
and Units Fair Value
Unvested at January 1 532,609 $ 13.15
Granted 222,964 11.38
Vested ( 191,653 ) 13.95
Forfeited ( 42,111 ) 14.15

Note 10Regulatory & 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 June 30, 2021, the Bank exceeded those thresholds.

At June 30, 2021, the Bank’s Tier 1 capital leverage ratio was 10.63 %, a decrease of 11 basis points from December 31, 2020, but is well above the 8.00 % objective. The Bank’s total capital ratio was 16.33 %, an increase of 133 basis points from December 31, 2020, and also well 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 June 30, 2021, and December 31, 2020.

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” generally holding companies with consolidated assets of less than $3.0 billion. The Company is currently considered a “small bank holding company.” As we have total assets in excess of $3.0 billion as of June 30, 2021, we will no longer be considered a small bank holding company in March of 2022. 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, 2020, under the heading “Supervision and Regulation.”

At June 30, 2021, and December 31, 2020, 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:

1 Amounts are shown inclusive of a capital conservation buffer of 2.50%. Under the Federal Reserve’s Small Bank Holding Company Policy Statement, the Company is not subject to the minimum capital adequacy and capital conservation buffer capital requirements at the holding company level, unless otherwise advised by the Federal Reserve (such capital requirements are applicable only at the Bank level). Although the minimum regulatory capital requirements are not applicable to the Company, we calculate these ratios for our own planning and monitoring purposes.

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

28

Table of Contents

Notes to Consolidated Financial Statements

(Dollar amounts in thousands, except per share data, unaudited)

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. The cumulative amount that is not recognized in regulatory capital, in addition to the $ 3.8 million Day 1 impact of CECL adoption, will be phased in at 25% per year beginning January 1, 2022. As of June 30, 2021, the capital measures of the Company exclude $ 4.5 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.

Stock Repurchase Program

In September 2019, our board of directors authorized the repurchase of up to 1,494,826 shares of our common stock (the “Repurchase Program”). The Repurchase Program expired on September 19, 2020, however, on October 20, 2020, the Company received notice of non-objection from the Federal Reserve Bank of Chicago to extend the Repurchase Program through October 20, 2021. Repurchases by us under the Repurchase Program may be made from time to time through open market purchases, trading plans established in accordance with SEC rules, privately negotiated transactions, or by other means. During the second quarter of 2021, we repurchased 310,900 shares of our common stock at a weighted average price of $ 13.55 per share, pursuant to the Repurchase Program. As of June 30, 2021, 1,485,307 shares have been repurchased since the program’s inception, and 9,519 shares remain available for repurchase under the Repurchase Program.

Note 11Fair 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.

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.

29

(Dollar amounts in thousands, except per share data, unaudited)

● 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.

The following table and commentary presents quantitative and qualitative information about Level 3 fair value measurements as of December 31, 2020:

Weighted
Measured at fair value Unobservable Average
on a recurring basis: Fair Value Valuation Methodology Inputs Range of Input of Inputs
Mortgage servicing rights $ 4,224 Discounted Cash Flow Discount Rate 11.0 - 15.0 % 11.0 %
Prepayment Speed 5.5 - 59.1 19.5 %

In addition to the above, Level 3 fair value measurement included $ 5.0 million for state and political subdivisions representing various local municipality securities at June 30, 2021. This was classified as securities available-for-sale, and was 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 June 30, 2020, was $ 4.7 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 June 30, 2021, and December 31, 2020, respectively, the following tables provide the level of valuation assumptions used to determine each valuation and the carrying value of the related assets:

June 30, 2021
Level 1 Level 2 Level 3 Total
Individually evaluated loans 1 $ - $ - $ 12,463 $ 12,463
Other real estate owned, net 2 - - 1,877 1,877
Total $ - $ - $ 14,340 $ 14,340

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; had a carrying amount of $ 17.0 million and a valuation allowance of $ 4.5 million resulting in an increase of specific allocations within the allowance for credit losses on loans of $ 1.9 million for the six months ended June 30, 2021.

2 OREO is measured at fair value, less costs to sell, and had a net carrying amount of $ 1.9 million at June 30, 2021, which is made up of the outstanding balance of $ 3.2 million, net of a valuation allowance of $ 1.3 million.

December 31, 2020
Level 1 Level 2 Level 3 Total
Individually evaluated loans 1 $ - $ - $ 9,675 $ 9,675
Other real estate owned, net 2 - - 2,474 2,474
Total $ - $ - $ 12,149 $ 12,149

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; had a carrying amount of $ 12.3 million and a valuation allowance of $ 2.6 million resulting in an increase of specific allocations within the allowance for credit losses on loans of $ 1.4 million for the year ended December 31, 2020.

2 OREO is measured at fair value, less costs to sell, and had a net carrying amount of $ 2.5 million at December 31, 2020, which is made up of the outstanding balance of $ 4.1 million, net of a valuation allowance of $ 1.6 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.

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. FHLBC stock is carried at cost and considered a Level 2 fair value. June 30, 2021 and December 31, 2020, 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.

The carrying amount and estimated fair values of financial instruments were as follows:

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 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

35

Notes to Consolidated Financial Statements

(Dollar amounts in thousands, except per share data, unaudited)

months, the Company estimates that an additional $ 186,000 will be reclassified as an increase to interest income and an additional $ 172,000 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 June 30, 2021, 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 changed from fixed rate to floating rate on June 15, 2017. The cash flow hedge has a maturity date of June 15, 2037.

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 held $ 1.0 million and $ 1.4 million of cash collateral related to one correspondent financial institution to cover the loan pool hedge mark to market valuation at June 30, 2021, and December 31, 2020, respectively.

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 had $ 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 June 30, 2021 and December 31, 2020. At June 30, 2021, the notional amount of non-hedging interest rate swaps was $ 175.5 million with a weighted average maturity of 4.3 years. At December 31, 2020, the notional amount of non-hedging interest rate swaps was $ 189.1 million with a weighted average maturity of 4.7 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 June 30, 2021 and December 31, 2020.

Disclosure of the Effect of Fair Value and Cash Flow Hedge Accounting

The fair value and cash flow hedge accounting related to derivatives covered under ASC Subtopic 815-20 impacted Accumulated Other Comprehensive Income (“AOCI”) and the Income Statement. The loss recognized in AOCI on derivatives totaled $ 1.9 million as of June 30, 2021, and $ 3.8 million as of June 30, 2020. The amount of the gain or (loss) reclassified from AOCI to interest income or interest expense on the income statement totaled $ 26,000 and ($ 90,000 ) for the six months ended June 30, 2021, and June 30, 2020, 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.

(Dollar amounts in thousands, except per share data, unaudited)

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 June 30, 2021, and December 31, 2020.

The following table is a summary of letter of credit commitments:

As of June 30, 2021, the Company evaluated current market conditions, including the impacts related to COVID-19 and market interest rates during the second quarter of 2021, and based on that analysis under the CECL methodology, the Company determined credit losses related to unfunded commitments totaled $ 2.3 million. The decrease in the ACL for unfunded commitments of $ 1.2 million for the second quarter of 2021, 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.

COVID-19

The COVID-19 pandemic and variants of the virus continue to create disruptions to the global economy and financial markets and to businesses and the lives of individuals throughout the world. The impact of the COVID-19 pandemic and its related variants is fluid and continues to evolve, adversely affecting many of our clients. Our business , financial condition and results of operations generally rely upon the ability of our borrowers to repay their loans, the value of collateral underlying our secured loans, and demand for loans and other products and services we offer, which are highly dependent on the business environment in our primary markets where it operates and in the United States as a whole. The unprecedented and rapid spread of COVID-19 and its variants and their associated impacts on trade (including supply chains and export levels), travel, employee productivity, unemployment, consumer spending, and other economic activities have resulted and continue to result in less economic activity, and volatility and disruption in financial markets. In addition, due to the COVID-19 pandemic, market interest rates declined to historic lows. These reductions in interest rates and the other effects of the COVID-19 pandemic have had, and are expected to continue to have, possibly materially, adverse effects on our business, financial condition and results of operations. The ultimate extent of the impact of the COVID-19 pandemic on our business, financial condition and results of operations is currently uncertain and will depend on various developments and other factors, including the effect of

39

Table of Contents

governmental and private sector initiatives, the effect of the continued rollout of vaccinations for the virus, whether such vaccinations will be effective against any resurgence of the virus and its variants, including any new strains, and the ability for customers and businesses to return to, and remain in, their pre-pandemic routines. In addition, it is reasonably possible that certain significant estimates made in our financial statements could be materially and adversely affected in the near term as a result of these conditions.

Results of Operation and Financial Condition

We are monitoring the impact of the COVID-19 pandemic on our results of operation and financial condition. To date, the COVID-19 pandemic has not significantly impacted the health of the overall real estate industry in our markets, which have reflected relative stability over the past three years. In addition, we have not experienced significant incurred losses on loans or received communications from our borrowers that significant losses are imminent. While management does not currently expect the next year to result in the precipitous decline in the value of certain real estate assets similar to the declines seen in 2009 to 2010, our forecast includes assumptions for certain loss scenarios that may occur due to the exhaustion of federal stimulus funds or a decrease in market valuations. Accordingly, we determined it prudent to increase our allowance for credit losses to $33.9 million as of December 31, 2020, driven by both our adoption of the new CECL methodology and the expected impact of the COVID-19 pandemic and market interest rate reductions in anticipation of continued market risk and uncertainty. During the first six months of 2021, unemployment expectations and other market indicators reflected an improving economic outlook, which resulted in a $3.0 million release of our provision for credit losses in the first quarter of 2021, and a $3.5 million release of provision for credit losses in the second quarter of 2021. The total release of credit losses for the first six months of 2021 of $6.5 million is comprised of a $5.7 million reserve release on loans and a $766,000 release of expense in our provision for credit losses on unfunded commitments.

We also adjust our investment securities portfolio to fair value each period end and review for any impairment that would require a provision for credit losses. At this time, we have determined there is no need for a provision for credit losses related to our investment securities portfolio. Because of changing economic and market conditions affecting issuers, we may be required to recognize impairments in the future on the securities we hold as well as experience reductions in other comprehensive income. We cannot currently determine the ultimate impact of the pandemic on the long-term value of our portfolio.

As of June 30, 2021 and December 31, 2020, we had $18.6 million of goodwill. At November 30, 2020, we performed our recurring annual review for any goodwill impairment. We determined no goodwill impairment existed, however, continued delayed recovery or further deterioration in market conditions related to the general economy, financial markets, and the associated impacts on our customers, employees and vendors, among other factors, could significantly impact the impairment analysis and may result in future goodwill impairment charges that, if incurred, could have a material adverse effect on our results of operations and financial condition.

To more fully support our customers during the pandemic, we established client assistance programs, including offering commercial, consumer, and mortgage loan payment deferrals for certain clients. As of June 30, 2021, we have executed 506 of these deferrals on loan balances of $237.8 million since March 31, 2020. In accordance with interagency guidance issued in March 2020, these short term deferrals were not considered troubled debt restructurings. As of June 30, 2021, 488 loans previously in deferral status, representing loan balances of $228.7 million, had resumed payments or paid off, and 18 loans totaling $9.1 million remained in active deferral status, of which only $2.4 million were in nonaccrual status. We also suspended late fees for consumer loans through June 30, 2020, and, although consumer late fees have been reinstated, we will continue to evaluate any late fee suspension based on the borrower’s financial situation and prior payment history. In addition, we paused new foreclosure and repossession actions through June 30, 2021, and will continue to re-evaluate these activities based on the ongoing COVID-19 pandemic. These programs may negatively impact our revenue and other results of operations in the near term and, if not effective in mitigating the effect of COVID-19 on our customers, may adversely affect our business and results of operations more substantially over a longer period of time. Future governmental actions may require these and other types of customer-related responses.

During 2020, as part of the first round of the SBA Paycheck Protection Program (“PPP”), we processed 746 PPP loan applications, representing a total of $136.7 million. In January through May 2021, we processed an additional 574 PPP loans, totaling $62.3 million, as part of the second round of the program, before the program expired on May 31, 2021. We started the application process for loan forgiveness for the first round of PPP loans in October 2020, and we continued to receive funds for forgiven loans from both the first and second round of PPP loans during the first six months of 2021. As of June 30, 2021, we have 518 loan, which totaled $70.2 million, still outstanding under the PPP program. We expect the application process for loan forgiveness to continue through the third quarter of 2021, with funds to be received from the SBA for the forgiven loans through the remainder of 2021. We recorded $832,000 of net fee and interest income on PPP loans in the second quarter of 2021, and $1.6 million of net fee and interest income on PPP loans in the first six

months of 2021. As of June 30, 2021, unearned net fee income on both first and second round PPP loans totaled $2.3 million. In addition, as of June 30, 2021, we had originated two loans with a total outstanding balance of $268,000 under the Main Street Lending Program.

Capital and Liquidity

As of June 30, 2021, all of our capital ratios were in excess of all regulatory requirements. While we believe that we have sufficient capital to withstand an extended economic recession brought about by the COVID-19 pandemic, our reported and regulatory capital ratios could be adversely impacted by credit losses.

We believe there could be potential stresses on liquidity management as a result of the COVID-19 pandemic. For instance, as customers manage their own liquidity stress, we could experience an increase in the utilization of existing lines of credit.

We have developed new processes to monitor our liquidity on a daily basis, and have run stress testing based on various economic assumptions under stress and severe stress scenarios. In addition, management continued to communicate bi-weekly through June 30, 2021, in structured meetings with key staff to ensure all current events related to the COVID-19 pandemic, such as federal government stimulus check receipt, PPP loan fundings and the forgiveness application process, are managed appropriately.

Financial Overview

Our community-focused banking franchise experienced a decrease in total loans in the first six months of 2021, compared to the year ended December 31, 2020, and a decrease in total loans compared to the second quarter of 2020, but we believe we are positioned for moderate loan growth as we continue to serve our customers’ needs in a competitive economic environment. Given the unprecedented nature of the COVID-19 pandemic and any potential related variants, it is difficult to predict the full impact the pandemic will have on our business. We are continuing to seek to provide value to our customers and the communities in which we operate, by executing on growth opportunities in our local markets and developing new banking relationships, while ensuring the safety and soundness of our Bank, our customers and our employees during the COVID-19 pandemic.

The following provides an overview of some of the factors impacting our financial performance for the three month period ended June 30, 2021, compared to the like period ended June 30, 2020:

● Net income for the second quarter of 2021 was $8.8 million, or $0.30 per diluted share, compared to $9.2 million, or $0.31 per diluted share, for the second quarter of 2020.

● Net interest and dividend income was $22.0 million for the second quarter of 2021, compared to $22.7 million for the second quarter of 2020. The decrease in 2021 was primarily due to the year over year decline in interest and dividend income of $1.5 million, primarily due to loans resetting at lower interest rates, as well as a $149.0 million reduction in loan volume. Partially offsetting the reduction in interest and dividend income, was a decrease of $765,000 in interest expense in the second quarter of 2021, compared to the second quarter of 2020, primarily due to a reduction in time deposit interest expense of $1.0 million.

● The provision for credit losses resulted in a $3.5 million net benefit driven by a reserve release in the second quarter of 2021, consisting of a $2.3 million reserve release related to loans and a $1.2 million reserve release related to unfunded commitments, compared to a provision for credit losses of $2.1 million recorded in the second quarter of 2020. We adopted the new current expected credit losses accounting standard, or CECL, effective January 1, 2020, which measures the allowance based on management’s best estimate of lifetime expected credit losses inherent in our lending activities, which resulted in a $5.9 million allowance for credit losses related to loans and a $1.7 million allowance for credit losses related to unfunded commitments as of January 1, 2020. The provision expense recorded in 2020 was impacted by both our adoption of the new CECL methodology and the expected impact, as of March 31, 2020, of the COVID-19 pandemic on future losses.

● Noninterest income was $7.9 million for the second quarter of 2021, compared to $10.7 million for the second quarter of 2020. The decrease in 2021 was primarily due to a $3.5 million decrease in mortgage banking revenue, primarily stemming from a less favorable mark to market adjustment on MSRs of $588,000 and a $2.7 million decrease in net gain on sales of mortgage loans. In addition, a net decrease of $109,000 was recorded related to the cash surrender value of bank owned life insurance (“BOLI”) for the second quarter of 2021, compared the second quarter of 2020, as market interest rates have decreased quarter over quarter. Partially offsetting these decreases was an increase of $391,000 in wealth management fees, and an increase of $355,000 in card related income, as customer spending increased due to the easing of COVID-19 restrictions.

Table of Contents

● Noninterest expense was $21.4 million for the second quarter of 2021, compared to $18.9 million for the second quarter of 2020, an increase of $2.5 million, or 13.3%. The increase in 2021 was primarily due to an increase in salaries and employee benefits expense driven by an increase in annual officer incentive expense and related payroll taxes and Company 401K match, and increases in occupancy, furniture and equipment expense.

● The provision for income taxes was $3.2 million for the second quarter of 2021, compared to a $3.1 million for the second quarter of 2020. Pretax income was $12.0 million in the second quarter of 2021, compared to a $12.4 million for the second quarter of 2020.

● Asset quality remained consistent with nonperforming loans as a percent of total loans remaining steady at 1.2% as of June 30, 2021, 1.1% as of December 31, 2020, and 1.0% as of June 30, 2020.

● During the second quarter of 2021, we repurchased 310,900 shares of our common stock at a weighted average price of $13.55 per share pursuant to our stock repurchase program.

Critical Accounting Policies

Our consolidated financial statements are prepared based on the application of accounting policies in accordance with generally accepted accounting principles (“GAAP”) and follow general practices within the banking industry. These policies require the reliance on estimates and assumptions, which may prove inaccurate or are subject to variations. 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. Changes in underlying factors, assumptions, or estimates could have a material impact on our future financial condition and results of operations.

Of the significant accounting policies used in the preparation of our consolidated financial statements, we have identified certain items as critical accounting policies based on the associated estimates, assumptions, judgments and complexity. See “ Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies ” in our Annual Report on Form 10-K for the year ended December 31, 2020. There have been no material changes to our critical accounting policies or the estimates made pursuant to those policies during the most recent quarter from those disclosed in our 2020 Annual Report in Form 10-K.

Non-GAAP Financial Measures

This report contains references to financial measures that are not defined in GAAP. Such non-GAAP financial measures include the presentation of net interest income and net interest margin on a tax equivalent (“TE”) basis, our adjusted efficiency ratio, our tangible common equity to tangible assets ratio, and our core net interest margin on a TE basis. Management believes that the presentation of these non-GAAP financial measures (a) provides important supplemental information that contributes to a proper understanding of our operating performance, (b) enables a more complete understanding of factors and trends affecting our business, and (c) allows investors to evaluate our performance in a manner similar to management, the financial services industry, bank stock analysts, and bank regulators. Management uses non-GAAP measures as follows: in the preparation of our operating budgets, monthly financial performance reporting, and in our presentation to investors of our performance. However, we acknowledge that these non-GAAP financial measures have a number of limitations. Limitations associated with non-GAAP financial measures include the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently. These disclosures should not be considered an alternative to our GAAP results. A reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures is presented below or alongside the first instance where each non-GAAP financial measure is used.

Results of Operations

Overview

Three months ended June 30, 2021 and 2020

Our income before taxes was $12.0 million in the second quarter of 2021 compared to $12.4 million in the second quarter of 2020. This decrease in pretax income was primarily due to a $2.8 million decrease in noninterest income, primarily due to a $3.5 million decline in

42

Table of Contents

mortgage banking income year over year, and a $2.5 million increase in noninterest expense, primarily due to an increase in salaries and employee benefits and occupancy, furniture and equipment expense. Also contributing to the decline was a $753,000 decrease in net interest and dividend income due to loans resetting at lower interest rates over the past year. These decreases to pretax income were partially offset by a $3.5 million release of provision for credit losses expense in the second quarter of 2021, compared to provision for credit losses of $2.1 million in the like quarter of 2020. Our net income was $8.8 million, or $0.30 per diluted share, for the second quarter of 2021, compared to net income of $9.2 million, or $0.31 per diluted share, for the second quarter of 2020.

Net interest and dividend income was $22.0 million in the second quarter of 2021, compared to $22.7 million in the second quarter of 2020. The $753,000 decrease was primarily driven by a $1.5 million reduction in interest income on loans due to the lower interest rate environment year over year as many variable rate loans reset over the past twelve months. Partially offsetting this increase was $765,000 decrease in interest expense in the second quarter of 2021, compared to the second quarter of 2020, primarily due to a reduction in time deposit interest expense of $1.0 million, due to a decrease in interest rates and volume reductions.

Management has remained diligent in reviewing our loan portfolio to analyze and determine if charge-offs are required. Average loans, including loans held for sale, decreased $121.1 million in the second quarter of 2021, compared to the second quarter of 2020, stemming primarily from $128.8 million of PPP loans forgiven in the past nine months, and loan paydowns due to growth in our borrowers’ liquidity year over year.

Six months ended June 30, 2021 and 2020

Our income before taxes was $28.1 million for the six months ended June 30, 2021, compared to $12.4 million for the six months ended June 30, 2020. This $15.7 million increase in pretax income was primarily due to a $6.5 million release of provision for credit losses expense for the six months ended June 30, 2021, compared to a $10.1 million provision for credit losses for the like period in 2020, due both to our adoption of the new CECL methodology effective January 1, 2020 and the expected impact, as of June 30, 2020, of the COVID-19 pandemic and related market interest rate reductions. Due to an improved unemployment forecast and our charge-offs recorded to date, our projected credit losses have decreased over the past year, resulting in the reversal in 2021 of a portion of our reserves recorded in 2020. Our net income was $20.7 million, or $0.70 per diluted share, for the six months ended June 30, 2021, compared to net income of $9.5 million, or $0.31 per diluted share, for the six months ended June 30, 2020.

Net interest and dividend income was $45.5 million for the six months ended June 30, 2021, compared to $45.4 million for the same period of 2020. While net interest and dividend income remained relatively flat interest and dividend income decreased $3.6 million year over year, due to the reduction in interest rates and a decline in loan volumes. This decrease was offset by a reduction in interest expense for the six months ended June 30, 2021, compared to the like 2020 period, due to the reduction in interest rates on interest-bearing deposits, as well as our redemption of the Old Second Capital Trust I trust preferred securities and related subordinated debentures in the first quarter of 2020.

Net Interest Income

Net interest income, which is our primary source of earnings, is the difference between interest income earned on interest-earning assets, such as loans and investment securities, as well as accretion income on purchased loans, and interest incurred on interest-bearing liabilities, such as deposits and borrowings. Net interest income depends upon the relative mix of interest-earning assets and interest-bearing liabilities, the ratio of interest-earning assets to total assets and of interest-bearing liabilities to total funding sources, and movements in market interest rates. Our net interest income can be significantly influenced by a variety of factors, including overall loan demand, economic conditions, credit risk, the amount of nonearning assets including nonperforming loans and OREO, the amounts of and rates at which assets and liabilities reprice, variances in prepayment of loans and securities, early withdrawal of deposits, exercise of call options on borrowings or securities, a general rise or decline in interest rates, changes in the slope of the yield-curve, and balance sheet growth or contraction.

Three months ended June 30, 2021 and 2020

Our net interest and dividend income decreased by $753,000 to $22.0 million, for the second quarter of 2021, from $22.7 million for the second quarter of 2020. This decrease was attributable to a $1.5 million, or 5.9%, decrease in interest and dividend income, primarily due to lower interest rates on loans and securities year over year. Partially offsetting this decrease in interest and dividend income, was a $765,000 decrease in interest expense in the second quarter of 2021, compared to the second quarter of 2020, primarily due to a decline in time deposit interest expense due to the decrease in interest rates and volume reductions. Net interest and dividend income for the second quarter of 2021 reflected a decrease of $1.6 million, or 6.7%, compared to the first quarter of 2021

Table of Contents

Average earning assets for the second quarter of 2021 were $3.05 billion, reflecting an increase of $138.0 million, or 4.7%, compared to the first quarter of 2021, and an increase of $386.3 million, or 14.5%, compared to the second quarter of 2020. Average interest earning deposits with financial institutions totaled $499.6 million for the second quarter of 2021, which reflected an increase of $140.0 million compared to the first quarter of 2021, and an increase of $346.0 million compared to the second quarter of 2020. The yield on average interest earning deposits was eleven basis points for both the second quarter of 2021 and the second quarter of 2020, but the increase in balances in the second quarter of 2021 drove the overall reduction in the yield on interest earning assets year over year. Total average loans, including loans held-for-sale, totaled $1.93 billion in the second quarter of 2021, which reflected a decrease of $83.8 million compared to the first quarter of 2021, and a decrease of $121.1 million compared to the second quarter of 2020. The decline in average loan balances year over year was primarily due to a decrease in commercial loans related to PPP loan payoffs, net of originations, and early payoffs on other commercial loans due to higher levels of borrower liquidity. This decline in loan volumes was exacerbated by the reduction in market interest rates over the past year, both of which resulted in a decrease in interest income of $1.5 million related to loans in the year over year period. For the second quarter of 2021, the yield on average loans decreased to 4.33%, compared to the yield on average loans of 4.48% for the first quarter of 2021, and 4.40% for the second quarter of 2020. Securities also reflected a reduction in interest income year over year, due to decreases in market interest rates over the past year, partially offset by growth in volumes. Total average securities for the second quarter of 2021 increased $81.8 million from the first quarter of 2021, and increased $161.4 million from the second quarter of 2020. The yield on average securities declined to 2.24% for the second quarter of 2021, compared to 2.49% for the first quarter of 2021 and 3.07% for second quarter of 2020.

Average interest bearing liabilities increased $64.9 million, or 3.6%, in the second quarter of 2021, compared to the first quarter of 2021, primarily driven by a $24.6 million increase in average interest bearing deposits and a $56.1 million increase in subordinated debentures. Average interest bearing liabilities increased $189.7 million in the second quarter of 2021, compared to the second quarter of 2020, primarily driven by a $124.3 million increase in interest bearing deposits, a $21.9 million increase in securities sold under repurchase agreements, and a $56.1 million increase in subordinated debentures. The cost of interest bearing liabilities for the second quarter of 2021 decreased by seven basis points from the first quarter of 2021, and decreased 24 basis points from the second quarter of 2020. Growth in our average noninterest bearing demand deposits of $157.8 million in the year over year period has assisted us in controlling our cost of funds stemming from average interest bearing deposits and borrowings, which totaled 0.31% for the second quarter of 2021, 0.27% for the first quarter of 2021, and 0.48% for the second quarter of 2020.

In the second quarter of 2021, we entered into Subordinated Note Purchase Agreements with certain qualified institutional buyers pursuant to which 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”). We sold the Notes to eligible purchasers in a private offering, and the proceeds of this issuance are intended to be used 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% through April 14, 2026, payable semi-annually in arrears. As of April 15, 2026 forward, the interest rate on the Notes will generally reset quarterly to a rate equal to Three-Month Term SOFR (as defined by the Note) plus 273 basis points, payable quarterly in arrears. The Notes have a stated maturity of April 15, 2031, and are redeemable, in whole are in part, on April 15, 2026, or any interest payment date thereafter, and at any time upon the occurrence of certain events.

Due to the significant increase in cash and due from banks stemming from federal stimulus funds received and PPP loan forgiveness, we had minimal average other short-term borrowings, which consist of FHLBC advances, in the second quarter of 2021, compared to no balance in the first quarter of 2021, and $8.4 million in the second quarter of 2020. As of June 30, 2021, notes payable and other borrowings consisted of one long-term FHLBC advance of $6.2 million, and $15.0 million outstanding on a term note with a correspondent bank originated in the first quarter of 2020.

Our net interest margin (GAAP) decreased 39 basis points to 2.88% for the second quarter of 2021, compared to 3.27% for the first quarter of 2021, and decreased 54 basis points compared to 3.42% for the second quarter of 2020. Our net interest margin (TE) decreased 40 basis points to 2.93% for the second quarter of 2021, compared to 3.33% for the first quarter of 2021, and decreased 55 basis points compared to 3.48% for the second quarter of 2020. Our core net interest margin (TE), a non-GAAP financial measure that excludes the impact of our PPP loans, was 2.91% for the second quarter of 2021, compared to 3.33% for the first quarter of 2021 and 3.51% for the second quarter of 2020. The reductions year over year were due primarily to the lower level of market interest rates over the majority of the past twelve months, the related rate resets on loans and securities during the past year, and the increase in liquidity on the balance sheet.

Six months ended June 30, 2021 and 2020

Our net interest and dividend income increased by $132,000, to $45.5 million for the six months ended June 30, 2021, compared to $45.4 million for the six months ended June 30, 2020. This increase was attributable to a $3.7 million decrease in total interest expense, which was materially offset by a $3.6 million decrease in interest and dividend income for the six months ended June 30, 2021, compared to the

Table of Contents

six months ended June 30, 2020. The reduction in market interest rates year over year drove the decrease in interest income on loans and securities, as well as the decrease in rates paid on interest bearing deposits, specifically impacting time deposits as both rate and volume declines occurred year over year.

Average earning assets for the six months ended June 30, 2021 were $2.99 billion, reflecting an increase of $422.2 million, or 16.5%, compared to the six months ended June 30, 2020. The yield on average earning assets for the six months ended June 30, 2021 was 3.40%, compared to 4.23% for the six months ended June 30, 2020. Total average loans, including loans held-for-sale, totaled $1.97 billion for the six months ended June 30, 2021, which reflected a decrease of $26.1 million, compared to the six months ended June 30, 2020. The decline in average loan balances and market interest rate reductions resulted in a $2.9 million decrease in interest income for the six months ended June 30, 2021, compared to the like period in 2020. For the six months ended June 30, 2021, yields on average securities decreased by 88 basis points and yields on average loans decreased by 23 basis points, each as compared to the six months ended June 30, 2020, due primarily to the falling interest rate environment. Average interest earning deposits with financial institutions increased $339.2 million in the six months ended June 30, 2021 compared to the prior year like period as consumer spending declined as a result of the COVID-19 pandemic, in addition to federal stimulus funds received by our depositors, which increased our liquidity.

Average interest bearing liabilities increased $175.5 million, or 10.5%, in the six months ended June 30, 2021, compared to the six months ended June 30, 2020. The increase was primarily due to growth in average interest bearing deposits of $143.3 million due to a decline in consumer spending during the COVID-19 pandemic and federal stimulus funds received from our depositors. In addition, securities sold under repurchase agreements increased $28.2 million, and average subordinated debt increased $28.2 million, due to the $60.0 million subordinated note issuance on April 6, 2021, as discussed above. Partially offsetting these increases to interest bearing liabilities, average other short-term borrowings, which primarily consist of FHLBC advances, decreased $15.7 million, and average junior subordinated debentures decreased $10.7 million due to the redemption of the trust preferred securities issued by Old Second Capital Trust I and the related $32.6 million of subordinated debentures in March 2020. The rate on our junior subordinated debentures was 9.08% for the six months ended June 30, 2020, as $635,000 of deferred issuance costs was expensed upon the redemption in 2020. Average noninterest bearing deposits increased $209.3 million in the six months ended June 30, 2021 compared to the six months ended June 30, 2020, due to a decline in consumer spending during the COVID-19 pandemic and federal stimulus funds received from our depositors. The cost of interest bearing liabilities decreased 49 basis points, to 45 basis points, for the six months ended June 30, 2021, from 94 basis points for the six months ended June 30, 2020.

Our net interest margin (GAAP) for the six months ended June 30, 2021 was 3.07% compared to 3.56% for the six months ended June 30, 2020, reflecting a 49 basis point decrease. Our net interest margin (TE) for the six months ended June 30, 2021 was 3.12% compared to 3.62% for the six months ended June 30, 2020, reflecting a 50 basis point decrease. The decrease in net interest margin for the six months ended June 30, 2021, compared to the six months ended June 30, 2020, was due primarily to reductions in the market interest rates, a decline of $26.1 million in average loans and loans held for sale, and the growth of our liquidity with an increase in cash and due from banks, which were not yet reinvested into higher yielding assets. These reductions to the net interest margin were partially offset by reductions in rates paid on deposits, and growth in noninterest bearing deposits, which drove down our overall cost of funds.

We continue to observe competitive pressure to maintain reduced interest rates on loans retained at renewal. While our loan prices are targeted to achieve certain returns on equity, significant competition for commercial and industrial loans as well as commercial real estate loans has put pressure on loan yields, and our stringent underwriting standards limit our ability to make higher-yielding loans.

The following table sets forth certain information relating to our average consolidated balance sheet and reflect the yield on average earning assets and cost of average interest bearing liabilities for the periods indicated. These yields reflect the related interest, on an annualized basis, divided by the average balance of assets or liabilities over the applicable period. Average balances are derived from daily balances. For purposes of discussion, net interest income and net interest income to total earning assets in the following tables have been adjusted to a non-GAAP TE basis using a marginal rate of 21% in 2021 and 2020 to more appropriately compare returns on tax-exempt loans and securities to other earning assets.

Table of Contents

$4.1 million decrease in residential mortgage banking revenue, primarily attributable to a $2.1 million decrease in mark to market gains on MSRs stemming from market interest rate changes and a $1.8 million decrease in net gain on sales of mortgage loans in the second quarter of 2021, compared to the first quarter of 2021. These decreases in noninterest income were partially offset by a $238,000 increase in wealth management income, and a $219,000 increase in card related income in the second quarter of 2021, compared to the prior quarter.

The decrease in noninterest income in the second quarter of 2021, compared to the second quarter of 2020, is primarily due to a $3.5 million decrease in residential mortgage banking revenue, which included a $588,000 decrease in mark to market MSR valuation and a $2.7 million decrease in net gain on sales of mortgage loans from the 2020 like period. Partially offsetting these decreases, was a $391,000 increase in wealth management income and a $355,000 increase in card related income in the second quarter of 2021, compared to the second quarter of 2020. The increase in card related income in the second quarter of 2021, compared to both the linked quarter and prior year quarter, resulted from reductions in COVID-19 related restrictions and the resultant increase in consumer spending.

Noninterest income for the six months ended June 30, 2021 increased $2.2 million, or 12.9%, compared to the six months ended June 30, 2020. This increase was primarily driven by a $1.4 million increase in total residential mortgage banking revenue primarily stemming from a $2.7 million increase in mark to market MSR valuation, partially offset by reductions in net gain on sales of mortgage loans and secondary mortgage fees. Wealth management income increased $636,000 for the six months ended June 30, 2021, compared to the like period in 2020, primarily due to an increase in customer liquidity and the resultant assets under management. In addition, card related income increased $515,000 for the six months ended June 30, 2021, compared to the prior year like period, as customers are starting to spend more as COVID-19 restrictions ease. These increases to noninterest income were partially offset by a decrease in service charges on deposits of $430,000 stemming from fewer non-sufficient fund fees collected due to higher customer liquidity.

1 The efficiency ratio shown in the table above is a GAAP financial measure calculated as noninterest expense, excluding amortization of core deposits and OREO expenses, divided by the sum of net interest income and total noninterest income less any BOLI death benefit recorded, net gains or losses on securities and mark to market gains or losses on MSRs.

2 The adjusted efficiency ratio shown in the table above is a non-GAAP financial measure calculated as noninterest expense, excluding amortization of core deposits and OREO expenses, divided by the sum of net interest income on a fully tax equivalent basis, total noninterest income less net gains or losses on securities and mark to market gains or losses on MSRs, and includes a tax equivalent adjustment on the change in cash surrender value of BOLI. See the section entitled “Reconciliation of Adjusted Efficiency Ratio Non-GAAP Financial Measures” on page 48 for a reconciliation of this non-GAAP measure to the most comparable GAAP equivalent.

Noninterest expense for the second quarter of 2021 decreased $337,000, or 1.6%, compared to the first quarter of 2021, but increased $2.5 million, or 13.3%, compared to the second quarter of 2020. The linked quarter decrease is primarily attributable to a $610,000 decrease in salaries and employee benefits in the second quarter of 2021 primarily driven by a $459,000 decrease in officer incentive compensation and a $370,000 decrease in benefits and other expenses, due to higher payroll taxes and 401K company matching expense related to the higher officer incentives in the first quarter of 2021. These decreases were partially offset by a $219,000 increase in salaries due to annual merit increases in March 2021, and a reversal of restricted stock compensation award expense in the first quarter of 2021 due to the achievement of only a partial award payout for performance-based restricted stock units. In addition, occupancy, furniture and equipment expense decreased $164,000 in the second quarter of 2021 compared to the linked quarter due to a decrease in snow removal costs and planned building maintenance. These decreases were partially offset by an increase in loan-related legal fees and other expenses, due to ongoing project-related consulting costs incurred, as well as an increase in employee related costs, as we return to more normalized events and meetings with our customers as the COVID-19 restrictions ease.

The year over year increase in noninterest expense is primarily attributable to a $1.6 million increase in salaries and employee benefits in the second quarter of 2021. Officer incentive increased $226,000 in the second quarter of 2021, compared to the second quarter of 2020, as incentive accruals in 2021 were at a higher rate than the prior year. Employee benefits expense increased $481,000 in the second quarter of 2021, compared to the second quarter of 2020, due to an increase in payroll taxes and 401K company matching expense commensurate with the higher salaries and incentives paid in 2021, as well as higher employee insurance costs. We also had increases in the year over year period in occupancy, furniture and equipment of $368,000 due to an increase in planned building repairs, and an increase in card related expense of $112,000 as customers began to increase their spending as the COVID-19 pandemic restrictions subsided. Finally, other expense increased $415,000 due to growth in consulting fees, and deferred director fees due to market interest rate increases year over year.

Noninterest expense for the six months ended June 30, 2021, increased $3.2 million, or 8.1%, compared to the six months ended June 30, 2020, primarily due to an increase in salaries and employee benefits due to annual merit increases in March 2021, as well as payout of officer incentives in early 2021 at a rate higher than that accrued for 2020 performance, and the resultant increase in accruals in 2021 to be paid out in 2022. In addition, occupancy, furniture and equipment expense increased $534,000, stemming from planned building repairs and maintenance; FDIC insurance increased $181,000 due to assessment credits received in early 2020 not repeated in 2021; card related expense increased $173,000, primarily due to a return to pre-COVID-19 customer spending levels in 2021; and other expense increased $533,000, primarily due to accruals for consulting and deferred director expense at a higher rate for the six months ended June 30 2021, compared to the prior year like period. Partially offsetting these increases was a $267,000 decrease in other real estate owned expense, net, as property holdings have decreased $3.2 million year over year.

Income Taxes

We recorded income tax expense of $3.2 million for the second quarter of 2021 on $12.0 million of pretax income, compared to income tax expense of $4.2 million on $16.1 million of pretax income in the first quarter of 2021, and an income tax expense of $3.1 million on $12.4 million of pretax income in the second quarter of 2020. The effective tax rate was 26.3% for the second quarter of 2021, 26.2% for the first quarter of 2021, and 25.4% for the second quarter of 2020.

Income tax expense reflected all relevant statutory tax rates and GAAP accounting. There were no significant changes in our ability to utilize our deferred tax assets during the quarter or six months ended June 30, 2021. We had no valuation reserve on the deferred tax assets as of June 30, 2021.

Financial Condition

Total assets increased $209.8 million to $3.25 billion at June 30, 2021, from $3.04 billion at December 31, 2020, due primarily to an increase in cash and cash equivalents of $262.9 million and securities available-for-sale of $83.8 million, partially offset by a reduction in loans of $131.5 million. We continue to actively assess potential investment opportunities for our excess liquidity. Total deposits were $2.68 billion at June 30, 2021, an increase of $145.0 million from December 31, 2020, primarily due to increases in noninterest bearing demand accounts, savings, money market and NOW accounts due to a decrease in consumer spending during the COVID-19 pandemic, and federal stimulus funds received by many depositors.

These purchases were partially offset by $51.1 million of calls, maturities and paydowns during the second quarter of 2021, and $8.2 million of security sales, as well as an unrealized mark to market gain adjustment of $3.3 million and net premium amortization of $560,000. During the second quarter of 2021 $2,000 of net security gains were recorded, compared to no security gains or losses, net, in the second quarter of 2020.

1 The “Other” segment includes consumer and overdrafts.

Total loans were $1.90 billion as of June 30, 2021, a decrease of $131.5 million from December 31, 2020. The decrease in total loans in the first six months of 2021, compared to December 31, 2020, was due primarily to forgiveness or payoff of 802 PPP loans that totaled $128.8 million within commercial loans, as well as reductions in the majority of our loan categories due to paydowns as commercial and consumer liquidity increased primarily due to the receipt of federal stimulus funds and capital expenditures decreased due to the COVID-19 pandemic. Total loans decreased $149.0 million from June 30, 2020 to June 30, 2021, primarily due to PPP loans forgiven, net of originations, as well as reductions in organic commercial loans due to payoffs related to borrower liquidity. As required by CECL, the balance (or amortized cost basis) of purchased credit deteriorated loans, or PCD loans (discussed below) are carried on a gross basis (rather than net of the associated credit loss estimate), and the expected credit losses for PCD loans are estimated and separately recognized as part of the allowance for credit losses, or ACL.

The quality of our loan portfolio is impacted not only by our credit decisions but also by the economic health of the communities in which we operate. Since we are located in a corridor with significant open space and undeveloped real estate, real estate lending (including commercial real estate, construction, residential, multifamily, and HELOCs) has been and continues to be a sizeable portion of our portfolio. These categories comprised 73.2% of the portfolio as of June 30, 2021, compared to 72.5% of the portfolio as of December 31, 2020. We continue to oversee and seek to manage our loan portfolio in accordance with interagency guidance on risk management.

Asset Quality

Nonperforming loans consist of nonaccrual loans, performing restructured accruing loans and loans 90 days or greater past due. Remediation work continues in all segments. Nonperforming loans increased by $76,000 to $23.1 million at June 30, 2021 from $23.0 million at December 31, 2020. Purchased credit deteriorated loans, or PCD loans, are purchased loans that, as of the date of acquisition, we determined had experienced a more-than-insignificant deterioration in credit quality since origination. PCD loans and their related deferred loan costs are included in our nonperforming loan disclosures, if such loans otherwise meet the definition of a nonperforming loan. Credit metrics continue to be relatively stable regarding nonperforming loan levels, and management is carefully monitoring loans considered to be in a classified status. Nonperforming loans as a percent of total loans were 1.2% as of June 30, 2021, 1.1% as of December 31, 2020, and 1.0% as of June 30, 2020. The distribution of our nonperforming loans is shown in the following table.

Net charge-offs of $65,000 were recorded for the second quarter of 2021, compared to net recoveries of $582,000 for the first quarter of 2021, and net charge-offs $167,000 for the second quarter of 2020, reflecting continuing management attention to credit quality and remediation efforts. The net charge-offs for the second quarter of 2021 were primarily due to one large commercial charge-off. We have continued our conservative loan valuations and aggressive recovery efforts on prior charge-offs.

Classified loans include nonaccrual, performing troubled debt restructurings and all other loans considered substandard. Classified assets include both classified loans and OREO. Loans classified as substandard are inadequately protected by either the current net worth and ability to meet payment obligations of the obligor, or by the collateral pledged to secure the loan, if any. These loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt and carry the distinct possibility that we will sustain some loss if deficiencies remain uncorrected.

1 The “Other” segment includes consumer and overdrafts.

Total classified loans and classified assets decreased as of June 30, 2021, from the levels at both December 31, 2020 and June 30 2020, primarily due to continued remediation efforts and the high level of paydowns and payoffs we have experienced due to increased borrower liquidity stemming from federal stimulus funds received by borrowers and other COVID-19 relief funding, such as PPP loans. Management monitors a ratio of classified assets to the sum of Bank Tier 1 capital and the ACL on loans as another measure of overall change in loan related asset quality, which is referred to as the “classified assets ratio.” The classified assets ratio was 10.75% for the period ended June 30, 2021, compared to 12.64% as of December 31, 2020, and 13.14% as of June 30, 2020. The decrease in the classified assets ratio for the period ended June 30, 2021, compared to June 30, 2020, is also due to the remediation efforts and borrower liquidity noted above, as well as growth in our capital level over the past year.

Allowance for Credit Losses on Loans

The provision for credit losses, which includes a provision for losses on unfunded commitments, is a charge to earnings to maintain the ACL at a level consistent with management’s assessment of expected losses in the loan portfolio at the balance sheet date. As of January 1, 2020, we adopted ASU 2016-13, or CECL.

We recorded a net release of $3.5 million in our provision for credit losses due to a reserve release for the second quarter of 2021, comprised of a $2.3 million reserve release related to loans and a $1.2 million reserve release related to unfunded commitments. We recorded a release of $3.0 million in our provision for credit losses for the first quarter of 2021, comprised of a $3.5 million reserve release related to loans and $470,000 of additional provision expense for credit losses on unfunded commitments, compared to a provision for credit losses recorded in the second quarter of 2020 of $2.1 million. In the second quarter of 2021, we determined a reserve release on loans was appropriate, after considering our low level of net charge-offs for the quarter of $65,000, and net recovery position of $517,000 year to date, as well as the impact of changes to our future loss rate assumptions based on a decrease to the unemployment factor projected for the life of the loans over the one year forecast period. In addition, we recorded a $1.2 million release to the provision for credit losses on unfunded commitments in the second quarter of 2021, primarily due to an updated analysis of line utilization rates over the past twelve months, as well as the roll off of prior historical periods with lower losses within the CECL model.

Management estimates the amount of provision required on a quarterly basis and records the appropriate provision expense, or release of expense, to maintain an adequate reserve for all potential and estimated credit losses on loan, leases and unfunded commitments. Our ACL on loans to total loans was 1.5% as of June 30, 2021 and June 30, 2020, compared to 1.7% at December 31, 2020. See Item 2 – Critical Accounting Policies in the Management Discussion and Analysis in this report for discussion of our ACL methodology on loans.

1 The “Other” segment includes consumer and overdrafts.

The coverage ratio of the ACL on loans to nonperforming loans was 123.9% as of June 30, 2021, which was a decrease from the coverage ratio of 146.2% as of March 31, 2021 and a decrease from 155.1% as of June 30, 2020. When measured as a percentage of average loans, our total ACL on loans was 1.49% for the six months ended June 30, 2021 and 1.57% for the like period of June 30, 2020.

In management’s judgment, an adequate ACL has been established to encompass the current lifetime expected credit losses at June 30, 2021, and general changes in lending policy, procedures and staffing, as well as other external factors, such as the impacts of the COVID-19 pandemic. However, there can be no assurance that actual losses will not exceed the estimated amounts in the future, based on unforeseen economic events, changes in business climates and the condition of collateral at the time of default and repossession. Further delayed recovery or further deterioration in market conditions related to COVID-19 and the associated impacts on our customers, changes in business climates and the condition of collateral at the time of default or repossession may revise our current expectations of future credit losses in future reporting periods.

As of June 30, 2021, OREO totaled $1.9 million, reflecting a $597,000 reduction from the $2.5 million at December 31, 2020, and a $3.2 million reduction from the $5.1 million at June 30, 2020. There were two property disposals for a total of $225,000 in net book value and no transfers to OREO from loans were recorded in the second quarter of 2021. There was one property addition for $93,000 in the second quarter of 2020. There were no property disposals in the second quarter of 2020. Valuation write-downs occurred in the second quarter of 2021 which totaled $61,000, compared to $93,000 of OREO valuation write-downs in the fourth quarter of 2020, and $60,000 of valuation write-downs recorded in the second quarter of 2020.

In management’s judgment, the property valuation allowance as established presents OREO at current estimates of fair value less estimated costs to sell; however, there can be no assurance that additional losses will not be incurred on disposals or upon updates to valuations in the future. Of note, properties valued in total at $1.1 million, or approximately 59.3% of total OREO at June 30, 2021, have been in OREO for five years or more.

The increase in deposits at June 30, 2021, compared to both December 31, 2020, and June 30, 2020, was due to increases in noninterest bearing demand, savings,

NOW, and money market accounts, with decreases noted in all maturity categories of certificates of deposit. These total deposit increases in the linked quarter as well as the year over year periods were primarily due to federal stimulus funds received by depositors and a decrease in consumer spending due to the COVID-19 pandemic.

In addition to deposits, we obtained funding from other sources in all periods presented. Securities sold under repurchase agreements totaled $68.6 million at June 30, 2021, a $1.6 million, or 2.4%, increase from $67.0 million at December 31, 2020. Our notes payable and other borrowings is comprised of one remaining $6.2 million long-term FHLBC advance, which matures on February 2, 2026, and $15.0 million outstanding on a $20.0 million term note originated with a correspondent bank in the first quarter of 2020, to facilitate the redemption of our Old Second Capital Trust I trust preferred securities and related junior subordinated debentures, completed on March 2, 2020. Notes payable and other borrowings of $21.2 million as of June 30, 2021, decreased $2.2 million from December 31, 2020, and decreased $4.3 million from June 30, 2020.

In the second quarter of 2021, we entered into Subordinated Note Purchase Agreements with certain qualified institutional buyers pursuant to which 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”). We sold the Notes to eligible purchasers in a private offering, and the proceeds of this issuance are intended to be used 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% through April 14, 2026, payable semi-annually in arrears. As of April 15, 2026 forward, the interest rate on the Notes will generally reset quarterly to a rate equal to Three-Month Term SOFR (as defined by the Note) plus 273 basis points, payable quarterly in arrears. The Notes have a stated maturity of April 15, 2031, and are redeemable, in whole are in part, on April 15, 2026, or any interest payment date thereafter, and at any time upon the occurrence of certain events.

The Company is indebted on senior notes originated in December 2016, totaling $44.4 million, net of deferred issuance costs, as of June 30, 2021. These notes mature in December 2026, and include interest payable semi-annually at 5.75% for five years. Beginning December 2021, the interest becomes payable quarterly at three month LIBOR plus 385 basis points. The Company is also indebted on $25.8 million, net of deferred issuance costs, of junior subordinated debentures, which are related to the trust preferred securities issued by its statutory trust subsidiary, Old Second Capital Trust II (“Trust II”). The Trust II issuance converted from fixed to floating rate at three month LIBOR plus 150 basis points on June 15, 2017. Upon conversion to a floating rate, we initiated a cash flow hedge which resulted in the total interest rate paid on this debt of 4.41% as of June 30, 2021, as compared to 6.77%, which was the rate paid during the period prior to the June 15, 2017, rate reset.

Capital

As of June 30, 2021, total stockholders’ equity was $315.9 million, which was an increase of $8.9 million from $307.1 million as of December 31, 2020. This increase is attributable to an increase in retained earnings of $19.0 million, comprised of net income year to date of $20.7 million, less a reduction to retained earnings of $1.7 million for payment of dividends to our common stockholders in the first six months of 2021. In addition, a decrease to accumulated other comprehensive income of $329,000 was recorded due to a net decrease in unrealized gains on available-for-sale securities, net of unrealized losses on swaps. Total stockholders’ equity was reduced by an increase of $8.1 million to our treasury stock in the first six months of 2021, primarily due to repurchases of our common shares pursuant to our stock repurchase program.

In the third quarter of 2019, our Board of Directors authorized a stock repurchase program, under which we were authorized to repurchase up to approximately 1.5 million shares (or approximately 5%) of our outstanding common stock through open market purchases, trading plans established in accordance with U.S. Securities and Exchange Commission rules, privately negotiated transactions, or by other means. The stock repurchase program expired on September 19, 2020; however, we received a notice of non-objection from the Federal Reserve Bank of Chicago to extend the previously authorized stock repurchase program through October 20, 2021. The actual means and timing of any repurchases, quantity of purchased shares and prices will be, subject to certain limitations, at the discretion of management and will depend on a number of factors, including, without limitation, market prices of our common stock, general market and economic condition, and applicable legal and regulatory requirements. These share purchases were funded by our cash on hand. During the second quarter of 2021, we repurchased 310,900 shares of our common stock at a weighted average price of $13.55 per share pursuant to our stock repurchase program. For the six months ended June 30, 2021, we repurchased 766,034 shares at a weighted average share price of $12.81 per share. To date, we have repurchased 1,485,307 shares of our common stock at a weighted average price of $10.31 per share, under our stock repurchase program. As of June 30, 2021, we have substantially completed the stock repurchase program.

1 Amounts are shown inclusive of a capital conservation buffer of 2.50%. Under the Federal Reserve’s Small Bank Holding Company Policy Statement, the Company is not subject to the minimum capital adequacy and capital conservation buffer capital requirements at the holding company level, unless otherwise advised by the Federal Reserve (such capital requirements are applicable only at the Bank level). Although the minimum regulatory capital requirements are not applicable to the Company, we calculate these ratios for our own planning and monitoring purposes.

2 The prompt corrective action provisions are only applicable at the Bank level.

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. The cumulative amount that is not recognized in regulatory capital, in addition to the $3.8 million Day One impact of CECL adoption, will be phased in at 25% per year beginning January 1, 2022. As of June 30, 2021, the capital measures of the Company exclude $4.5 million, which is the modified CECL transition adjustment.

As of June 30, 2021, the Company, on a consolidated basis, exceeded the minimum capital ratios to be deemed “well capitalized” and met the now fully phased-in capital conservation buffer requirements. In addition to the above regulatory ratios, our GAAP common equity to total assets ratio, which is used as a performance measurement for capital analysis and peer comparisons, decreased from 10.10% at December 31, 2020, to 9.72% at June 30, 2021. Our GAAP tangible common equity to tangible assets ratio was 9.15% at June 30, 2021, compared to 9.48% as of December 31, 2020. Our non-GAAP tangible common equity to tangible assets ratio, which management also considers a valuable performance measurement for capital analysis, decreased from 9.49% at December 31, 2020, to 9.16% at June 30, 2021, due to the growth in total tangible assets.

In November 2019, the federal banking agencies published final rules to provide an optional simplified measure of capital adequacy for qualifying community banking organizations, which we refer to as the community bank leverage ratio (“CBLR”) framework. Generally, under the CBLR framework, qualifying community banking organizations with total assets of less than $10 billion, and limited amounts of off-balance-sheet exposures and trading assets and liabilities, may elect whether to be subject to the CBLR framework if they have a CBLR of greater than 9%. Qualifying community banking organizations that elect to be subject to the CBLR framework and continue to meet all requirements under the framework would not be subject to risk-based or other leverage capital requirements and, in the case of an insured depository institution, would be considered to have met the well capitalized ratio requirements for purposes of the FDIC’s Prompt Corrective Action framework. The final rule became effective on January 1, 2020. We do not have any immediate plans to elect to use the community bank leverage ratio framework, but may make such an election in the future.

Liquidity

Liquidity is our ability to fund operations, to meet depositor withdrawals, to provide for customers’ credit needs, and to meet maturing obligations and existing commitments. Our liquidity principally depends on our cash flows from operating activities, investment in and maturity of assets, changes in balances of deposits and borrowings, and our ability to borrow funds. We monitor our borrowing capacity at the FHLBC as part of our liquidity management process as supervised by our Asset and Liability Committee (“ALCO”) and reviewed by our Board of Directors. In addition, due to the potential impacts on our liquidity stemming from the COVID-19 pandemic, our senior management team monitors cash balances daily to ensure we have adequate liquidity to meet our operational and financing needs. As of June 30, 2021, our cash on hand liquidity totaled $592.8 million, an increase of $262.9 million over cash balances held as of December 31, 2020.

Net cash inflows from operating activities were $24.5 million during the first six months of 2021, compared with net cash inflows of $20.8 million in the same period of 2020. Funds used to originate loans held-for-sale, net of proceeds from sales of loans held-for-sale, were a source of inflows for the first six months of 2021 and outflows for the like period of 2020. Interest paid, net of interest received, combined with changes in other assets and liabilities were a source of inflows for both the six months ended June 30, 2021, and the like period of 2020. The management of investing and financing activities, as well as market conditions, determines the level and the stability of net interest cash flows. Management’s policy is to mitigate the impact of changes in market interest rates to the extent possible, as part of the balance sheet management process.

Net cash inflows from investing activities were $47.0 million in the six months ended June 30, 2021, compared to net cash outflows of $83.7 million in the same period in 2020. In the first six months of 2021, securities transactions accounted for net outflows of $86.3 million, and the principal change on loans accounted for net inflows of $133.4 million. In the first six months of 2020, securities transactions accounted for net inflows of $40.7 million, and net principal on loans funded accounted for net outflows of $123.6 million. Proceeds from sales of OREO accounted for $565,000 and $311,000 in investing cash inflows for the six months ended June 30, 2021 and 2020, respectively.

Net cash inflows from financing activities in the six months ended June 30, 2021 were $191.4 million, compared with net cash inflows of $269.7 million in the six months ended June 30, 2020. Net deposit inflows in the first six months of 2021 were $144.9 million compared to net deposit inflows of $324.6 million in the first six months of 2020. Other short-term borrowings had no net cash outflows in the first six months of 2021, compared to $40.3 million in the first six months of 2020. Changes in securities sold under repurchase agreements accounted for $1.6 million and $3.4 million in net inflows for the six months ended June 30, 2021 and 2020, respectively. The redemption of our Old Second Capital Trust I trust preferred securities and related junior subordinated debentures resulted in cash outflows of $32.6 million in the first quarter of 2020, which was partially offset by a $20.0 million term note cash inflow which was originated to partially fund this trust preferred redemption; $15.0 million of this term note remains outstanding as of June 30, 2021. In

the second quarter of 2021, we issued $59.1 million of subordinated debentures, net of issuance costs; this cash is anticipated to be used for general corporate purposes, which may include, without limitation, the redemption of existing senior debt, common stock repurchases or strategic acquisitions.

Cash and cash equivalents for the six months ended June 30, 2021, totaled $592.8 million, as compared to $257.5 million as of June 30, 2020. In addition to cash and cash equivalents on hand or held as deposits with other financial institutions, we rely on funding sources from customer deposits, cash flows from securities available-for-sale and loans, and a line of credit with the FHLBC to meet potential liquidity needs. These sources of liquidity are immediately available to satisfy any funding requirements due to depositor or borrower demands through the ordinary course of our business. Additional sources of funding include a $20 million undrawn line of credit held by the Company with a third party financial institution, as well as unpledged securities available-for-sale.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

As part of our normal operations, we are subject to interest-rate risk on the assets we invest in (primarily loans and securities) and the liabilities we fund (primarily customer deposits and borrowed funds). Fluctuations in interest rates may result in changes in the fair market values of our financial instruments, cash flows, and net interest income. Like most financial institutions, we have an exposure to changes in both short-term and long-term interest rates.

The Federal Reserve has kept the target Fed Funds range of 0% to 0.25% since the first quarter of 2020, the latest implied Fed Funds Futures expects a rate hike in early 2023. The Fed has been aggressively purchasing various assets since March 2020. The Fed’s balance sheet experienced a 90% increase from about $4.2 trillion in early March 2020 to $8.1 trillion by the end of June 2021. Given rising inflation risks, tapering discussions are expected in the July 2021 meeting. We manage interest rate risk within guidelines established by policy which are intended to limit the amount of rate exposure. In practice, we seek to manage our interest rate risk exposure well within our guidelines so that such exposure does not pose a material risk to our future earnings.

We seek to manage various market risks in the normal course of our operations, including credit, liquidity risk, and interest-rate risk. Other types of market risk, such as foreign currency exchange risk and commodity price risk, do not arise in the normal course of our business activities and operations. In addition, since we do not hold a trading portfolio, we are not exposed to significant market risk from trading activities. Our interest rate risk exposures at June 30, 2021 and December 31, 2020 are outlined in the table below.

Our net income can be significantly influenced by a variety of external factors, including: overall economic conditions, policies and actions of regulatory authorities, the amounts of and rates at which assets and liabilities reprice, variances in prepayment of loans and securities other than those that are assumed, early withdrawal of deposits, exercise of call options on borrowings or securities, competition, a general rise or decline in interest rates, changes in the slope of the yield-curve, changes in historical relationships between indices (such as LIBOR and prime), and balance sheet growth or contraction. Our asset-liability committee seeks to manage interest rate risk under a variety of rate environments by structuring our balance sheet and off-balance sheet positions, which includes interest rate swap derivatives as discussed in Note 18 of our consolidated financial statements found in our Annual Report on Form 10-K for the year ended December 31, 2020. We seek to monitor and manage interest rate risk within approved policy guidelines and limits.

We use simulation analysis to quantify the impact of various rate scenarios on our net interest income. Specific cash flows, repricing characteristics, and embedded options of the assets and liabilities held by us are incorporated into the simulation model. Earnings at risk are calculated by comparing the net interest income of a stable interest rate environment to the net interest income of a different interest rate environment in order to determine the percentage change. As of December 31, 2020, we had notable amounts of earnings gains (in both dollars and percentage) should interest rates rise. Due to relatively low current market interest rates, it was not possible to calculate any down rate scenarios because many of the market interest rates would fall below zero in that scenario. The projected increases in income across all up rate interest rate shock scenarios as of June 30, 2021 were notably higher than December 31, 2020. This is driven by a change in the model calculation to better reflect repricing characteristics of the elevated cash balances.

The following table summarizes the effect on annual income before income taxes based upon an immediate increase or decrease in interest rates of 0.5%, 1%, and 2% and no change in the slope of the yield curve. Due to the low interest rate environment, it was not possible to calculate any down rate scenarios because rates would fall below zero in all down rate scenarios.

The amounts and assumptions used in the simulation model should not be viewed as indicative of expected actual results. Actual results will differ from simulated results due to timing, magnitude and frequency of interest rate changes as well as changes in market conditions and management strategies. The above results do not take into account any management action to mitigate potential risk.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures, as defined in Rule 13a-15(e) promulgated under the Securities and Exchange Act of 1934, as amended, as of June 30, 2021. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that as of June 30, 2021, the Company’s internal controls were effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Securities and Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified.

There were no changes in the Company’s internal controls over financial reporting during the quarter ended June 30, 2021, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

The design of any system of controls and procedures is based in part upon certain assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

The Company and its subsidiaries, from time to time, are involved in collection suits in the ordinary course of business against its debtors and are defendants in legal actions arising from normal business activities. Management, after consultation with legal counsel, believes that the ultimate liabilities, if any, resulting from these actions will not have a material adverse effect on the financial position of the Bank or on the consolidated financial position of the Company.

Item 1.A. Risk Factors

Investing in shares of our common stock involves certain risks, including those identified and described in Item 1A. of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, as well as cautionary statements contained in this Quarterly Report on Form 10-Q, including those under the caption “Cautionary Note Regarding Forward-Looking Statements” and in our other filings with the SEC.

Risks Related to the Proposed Merger with West Suburban

Combining the Company and West Suburban may be more difficult, costly or time consuming than expected and the anticipated benefits and cost savings of the Merger may not be realized.

The Company and West Suburban have operated and, until the completion of the Merger, will continue to operate, independently. The success of the proposed Merger, including anticipated benefits and cost savings, will depend, in part, on our ability to successfully combine and integrate our businesses with West Suburban in a manner that permits growth opportunities and does not materially disrupt the existing customer relations nor result in decreased revenues due to loss of customers. It is possible that the integration process could result in the loss of key employees, the disruption of either company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the combined company’s ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits and cost savings of the Merger. The loss of key employees could adversely affect our ability to successfully conduct our business, which could have an adverse effect on our financial results and the value of our common stock. If we experience difficulties with the integration process, the anticipated benefits of the Merger may not be realized fully or at all, or may take longer to realize than expected. As with any Merger of financial institutions, there also may be business disruptions that cause the Company and/or West Suburban to lose customers or cause customers to remove their accounts from the Bank and/or West Suburban Bank and move their business to competing financial institutions. Integration efforts between the two companies will also divert management attention and resources. These integration matters could have an adverse effect on each of the Company and West Suburban during this transition period and for an undetermined period after completion of the Merger on the combined company. In addition, the actual cost savings of the Merger could be less than anticipated.

The market price of our common stock after the proposed Merger with West Suburban may be affected by factors different from those affecting the shares of our common stock or West Suburban common stock currently.

If the proposed Merger with West Suburban is completed, holders of West Suburban common stock will become holders of our common stock. Our business differs from that of West Suburban. Accordingly, the results of operations and financial condition of the combined company and the market price of our common stock after the completion of the proposed Merger may be affected by factors different from those currently affecting the independent results of operations and financial condition of each of the Company and West Suburban.

We are subject to business uncertainties while the proposed Merger with West Suburban is pending.

Uncertainty about the effect of the proposed Merger with West Suburban on employees and customers may have an adverse effect on us. These uncertainties may impair our ability to attract, retain and motivate key personnel until the Merger is completed, and could cause customers and others that deal with us to seek to change existing business relationships. Retention of certain employees by us may be challenging while the Merger is pending, as certain employees may experience uncertainty about their future roles with the combined company. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with us, our business could be harmed.

The proposed Merger with West Suburban may distract our management from their other responsibilities.

The proposed Merger could cause our management to focus their time and energies on matters related to the Merger that otherwise would be directed to our business and operations. Any such distraction on the part of our management, if significant, could affect our ability to service existing business and develop new business and adversely affect our business and earnings before the Merger, or the business and earnings of the combined company after the Merger.

Failure to complete the proposed Merger could negatively impact the Company.

If the proposed Merger is not completed for any reason, including as a result of either our stockholders’ or West Suburban stockholders’ failure to approve the Merger Agreement, there may be various adverse consequences and we may experience negative reactions from the financial markets and from our customers and associates. For example, our business may have been impacted adversely by the failure to pursue other beneficial opportunities due to the focus of management on the Merger, without realizing any of the anticipated benefits

65

Table of Contents

of completing the Merger. Additionally, if the Merger Agreement is terminated, the market price of our common stock could decline to the extent that current market prices reflect a market assumption that the Merger will be beneficial and will be completed. We also could be subject to litigation related to any failure to complete the Merger or to proceedings commenced against us to perform our obligations under the Merger Agreement.

Additionally, we have incurred and will continue to incur substantial expenses in connection with the negotiation and completion of the transactions contemplated by the Merger Agreement, as well as the costs and expenses of preparing, filing, printing and mailing a joint proxy statement/prospectus, and all filing and other fees paid in connection with the Merger. If the Merger is not completed, we would have to pay these expenses without realizing the expected benefits of the Merger.

Regulatory approvals may not be received, may take longer than expected or may impose conditions that are not presently anticipated or that could have an adverse effect on the combined company following the proposed Merger.

Before the proposed Merger and the bank merger may be completed, various approvals, consents and non-objections must be obtained from the Board of Governors of the Federal Reserve System, the Office of the Comptroller of the Currency and other regulatory authorities. In determining whether to grant these approvals, the regulators consider a variety of factors. These approvals could be delayed or not obtained at all, including due to any or all of the following: an adverse development in either party’s regulatory standing, or any other factors considered by regulators in granting such approvals; governmental, political or community group inquiries, investigations or opposition; changes in legislation or the political environment, including as a result of Congressional leadership and regulatory agency leadership; or impacts and disruptions resulting from the COVID-19 pandemic.

The approvals that are granted may impose terms and conditions, limitations, obligations or costs, or place restrictions on the conduct of the combined company’s business or require changes to the terms of the transactions contemplated by the Merger Agreement. There can be no assurance that regulators will not impose any such conditions, limitations, obligations or restrictions or that such conditions, limitations, obligations or restrictions will not have the effect of delaying the completion of any of the transactions contemplated by the Merger Agreement, imposing additional material costs on or materially limiting the revenues of the combined company following the Merger or will otherwise reduce the anticipated benefits of the Merger. In addition, there can be no assurance that any such conditions, limitations, obligations or restrictions will not result in the delay or abandonment of the Merger.

If the proposed Merger is completed, holders of our common stock will have a reduced ownership and voting interest in the combined company after the Merger and will exercise less influence over management.

Holders of our common stock currently have the right to vote in the election of the board of directors and on other matters affecting us. If the Merger is completed, each West Suburban stockholder will become a stockholder of Old Second, and each Company and West Suburban stockholder will have a percentage ownership in the combined company that is smaller than the stockholder’s percentage ownership of either the Company or West Suburban individually. Based on the number of shares of our common stock and West Suburban outstanding as of June 30, 2021, and based on the number of shares of West Suburban common stock expected to be issued in the Merger, the former holders of West Suburban common stock, as a group, are estimated to own 36% of the outstanding shares of common stock of the combined company immediately after the Merger and current holders of our common stock, as a group, are estimated to own approximately 64% of the outstanding shares of common stock of the combined company immediately after the Merger. Because of this, holders of our common stock may have less influence on the management and policies of the combined company than they now have on our management and policies.

Various factors, including potential stockholder litigation, could prevent or delay the completion of the proposed Merger or otherwise negatively impact our business and operations.

The completion of the Merger is subject to closing conditions. Various factors, including potential stockholder litigation, could prevent or delay the completion of the proposed Merger or otherwise negatively impact our business and operations. Our stockholders may file lawsuits against us and/or the directors and officers of the Company in connection with the Merger. One of the conditions to the closing is that no order, injunction or similar decree issued by any governmental authority of competent jurisdiction or other legal restraint will prohibit the consummation of the transactions contemplated by the Merger Agreement. If any plaintiff were successful in obtaining an injunction prohibiting us from completing the Merger pursuant to the Merger Agreement, then such injunction may delay or prevent the effectiveness of the Merger. If a lawsuit is filed, we may incur costs in connection with the defense or settlement of any such lawsuits, which could have an adverse effect on our financial condition and results of operations and could prevent or delay the completion of the Merger.

Stock Repurchases

In September 2019, our board of directors authorized the repurchase of up to 1,494,826 shares of our common stock (the “Repurchase Program”). The Repurchase Program expired on September 19, 2020. However, on October 20, 2020, the Company received notice of non-objection from the Federal Reserve Bank of Chicago to extend the Repurchase Program through October 20, 2021. Repurchases by the Company under the Repurchase Program may be made from time to time through open market purchases, trading plans established in accordance with SEC rules, privately negotiated transactions, or by other means.

The actual means and timing of any repurchases, quantity of purchased shares and prices will be, subject to certain limitations, at the discretion of management and will depend on a number of factors, including, without limitation, market prices of our common stock, general market and economic conditions, and applicable legal and regulatory requirements. Repurchases under the Repurchase Program may be initiated, discontinued, suspended or restarted at any time provided that repurchases under the Repurchase Program after October 20, 2021, would require Federal Reserve non-objection or approval. We are not obligated to repurchase any shares under the Repurchase Program.

The following table presents our stock repurchases for the quarter ended June 30, 2021.
