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, but not limited to, management’s expectations regarding future plans, strategies and financial performance, including regulatory developments, industry and economic trends and estimates and assumptions underlying accounting policies. Forward-looking statements are based on our current beliefs, expectations and assumptions and on information currently available and, can be identified by the use of words such as “expects,” “seeks to,” “intends,” “believes,” “may,” “will,” “would,” “could,” “should,” “plan,” “anticipate,” “estimate,” “possible,” “likely” or the negative thereof as well as other similar words and expressions of the future. Forward-looking statements are subject to risks, uncertainties and assumptions that are difficult to predict as to timing, extent, likelihood and degree of occurrence, which could cause our actual results to differ materially from those anticipated in or by such statements. Potential risks and uncertainties include, but are not limited to, the following:

​

| ● | 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, including inflation, that may 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;

| ● | risks with respect to our ability to successfully expand and integrate businesses and operations that we acquire, such as the recent acquisition of West Suburban Bancorp, Inc., as well our ability to identify and complete future mergers or acquisitions;

| ● | 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 our adoption of the Current Expected Credit Losses (“ CECL”) model, 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 or negative changes in our capital position;

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

| ● | 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;

| ● | 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, such as the war in Ukraine, 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 2021 Annual Report on Form 10-K and in subsequent filings we make with the SEC.

​

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, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. These interim consolidated financial statements are unaudited and should be read in conjunction with the audited financial statements and notes included in Old Second Bancorp, Inc.’s (the “Company”) annual report on Form 10-K for the year ended December 31, 2021. Unless otherwise indicated, dollar amounts in the tables contained in the notes to the consolidated financial statements are in thousands. Certain items in prior periods have been reclassified to conform to the current presentation.

​

The Company’s consolidated financial statements are prepared in accordance with United States generally accepted accounting principles (“GAAP”) and follow general practices within the banking industry. Application of these principles requires management to make estimates, assumptions, and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the consolidated financial statements. Future changes in information may affect these estimates, assumptions, and judgments, which, in turn, may affect amounts reported in the consolidated financial statements.

​

See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates” and Note 1 – Summary of Significant Accounting Policies, both found in our Annual Report on Form 10-K for the year ended December 31, 2021, for further discussion of our Allowance for Credit Losses methodology, which now implements 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, which is considered a critical accounting estimate, 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.

​

Recent Accounting Pronouncements

The following is a summary of recent accounting pronouncements that have impacted or could potentially affect the Company:

​

ASU 2018-16, ASU 2020-04 and ASU 2021-01 - In October 2018, the Financial Standards Board, or FASB, issued ASU No. 2018-16 “Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting.” ASU 2018-16 adds the SOFR overnight index swap rate to the list of United States (U.S.) benchmark rates eligible for hedge accounting purposes, which is the fourth rate permissible to be used as a U.S. benchmark rate. This guidance is effective for annual and interim periods beginning after December 15, 2018, and we do not expect this guidance to have a material impact on the financial condition or liquidity of the Company. ASU 2020-04 and ASU 2021-01 Reference Rate Reform (Topic 848) were issued on March 12, 2020 and January 7, 2021, respectively, and each provide further guidance on optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships due to the discontinuation of LIBOR. In addition, on March 5, 2021, the International Swaps and Derivatives Association (“ISDA”) issued a statement with an “Index Cessation Event Announcement,” which confirmed the extension of the cessation of LIBOR-referenced rates from December 31, 2021, to June 30, 2023, for certain rate tenors.

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

The Company formed a LIBOR transition team in 2019, and has developed a project plan to assess the use of alternative indexes and to seek to ensure all financial instruments that reference LIBOR are identified, quantified, and researched for the LIBOR fallback language available or needed. The Company has completed the ISDA protocol adherence for LIBOR fallback language for all commercial swaps, has met with our commercial loan clients to also guide their swap fallback language adherence, and worked to revise all credit documents being issued by our Bank for new loans to ensure appropriate fallback language is included. We have discontinued the use of LIBOR as a reference rate for all consumer loans issued after July 31, 2021, and all commercial loans issued after December 31, 2021, with certain exceptions for those loans that were in the process of funding at the end of 2021. The Company’s systems have been updated to handle multiple SOFR-based indexes and we continue to meet regularly to plan for the transition of existing LIBOR exposures prior to the final LIBOR cessation date of June 30, 2023.

​

ASU 2022-01 – On March 28, 2022, the FASB issued ASU 2022-01”Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method.” ASU 2022-01 is effective for public business entities for fiscal years beginning after December 15, 2022, and also interim periods within those fiscal years. Early adoption is permitted if an entity has adopted ASU No. 2017-12 concurrently or prior. The goal of this new hedging standard is to better align the economic results of risk management activities with hedge accounting, by allowing multiple layers of a single closed portfolio to be hedged, as compared to the single-layer, or last of layer method, allowed with the adoption of ASU 2017-12.

​

The Company is currently reviewing ASU 2022-01 for the impact to derivative measurement and disclosures, and will assess any revisions needed for reporting purposes in the next few quarters. We anticipate adopting ASU 2022-01 no later than January 1, 2023.

​

ASU 2022-02 – On March 31, 2022, the FASB issued ASU 2022-02 “Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” ASU 2022-02 is effective for any entities that have adopted CECL, and is effective for fiscal years beginning after December 15, 2022, including interim periods within those years. The amendments eliminate certain troubled debt restructuring (“TDR”) recognition and measurement guidance previously in effect, and consideration of the TDRs similar to other modified loans under CECL is now required. ASU 2022-02 also requires enhancements to vintage loan disclosures, requiring detail be provided on current-period gross write-offs and disclosure of the amortized cost basis of financing receivables by credit quality indicators and by loan portfolio class of the gross charge-off based on year of origination.

​

The Company is currently reviewing ASU 2022-02 for the impact to TDR recognition, measurement and disclosures, and will assess any revisions needed for reporting purposes in the next few quarters. We anticipate adopting ASU 2022-02 as of January 1, 2023.

​

Change in Significant Accounting Policies

​

Significant accounting policies are presented in Note 1 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. These policies, along with the disclosures presented in the other financial statement notes and in this discussion, provide information on how significant assets and liabilities are valued in the consolidated financial statements and how those values are determined. During the second quarter of 2022, the Company had no changes to significant accounting policies or estimates.

​

Subsequent Events

​

On July 19, 2022, our Board of Directors declared a cash dividend of $0.05 per share payable on August 8, 2022, to stockholders of record as of July 29, 2022; dividends of $2.2 million are scheduled to be paid to stockholders on August 8, 2022.

​

Note 2 – Acquisition

​

On December 1, 2021, the Company completed its acquisition of West Suburban Bancorp, Inc. (“West Suburban”), a bank holding company, and its wholly owned subsidiary, West Suburban Bank, based in Lombard, Illinois, with operations throughout our existing market footprint. This acquisition brought increased scale and new markets to the Company, and provided new product offerings and line of business opportunities. At closing, the Company acquired $2.94 billion of assets, $1.50 billion of loans, $1.07 billion of securities, and $2.69 billion of deposits, net of fair value adjustments. Under the terms of the merger agreement, each outstanding share of West Suburban common stock was exchanged for 42.413 shares of Company common stock, plus $271.15 of cash. This resulted in merger

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

consideration of $295.2 million, based on the closing price of the Company’s common stock on the date of acquisition, which consisted of 15.7 million shares of the Company’s common stock and $100.7 million of cash. Goodwill of $67.7 million associated with the acquisition was recorded by the Company, which was the result of expected synergies, operational efficiencies and other factors.

​

The acquisition of West Suburban was accounted for as a business combination. We recorded the estimate of fair value based on initial valuations available at December 1, 2021. The determination of estimated fair value required management to make assumptions related to discount rates, expected future cash flows, market conditions and other future events that are often subjective in nature and may require adjustments. Accordingly, these estimated fair values are considered preliminary as of June 30, 2022, and are subject to adjustment for up to one year after December 1, 2021. These adjustments may include: (i) changes in deferred tax assets or liabilities related to fair value estimates and changes in the expected realization of items considered to be net operating loss carryforwards due to tax calculations still in process, and (ii) changes in goodwill as a result of the net effect of any adjustments. No adjustments were identified during the quarter ended June 30, 2022. None of the $67.7 million of goodwill recorded is expected to be deductible for income tax purposes.

​

The following table provides the preliminary purchase price allocation as of the December 1, 2021 closing date of the merger for the estimated fair value of the assets acquired and liabilities assumed, as recorded by the Company.

​

Purchased loans and leases that reflect a more-than-insignificant deterioration of credit from origination are considered purchased credit deteriorated (“PCD”) loans. For PCD loans, the initial estimate of expected credit losses was recognized in the allowance for credit losses (“ACL”) on the date of acquisition using the same methodology as other loans and leases held-for-investment. The following table provides a summary of loans purchased as part of the West Suburban acquisition which were individually evaluated and determined to be PCD loans at acquisition.

Note 3 – Securities

​

Investment Portfolio Management

​

Our investment portfolio serves the liquidity needs and income objectives of the Company. While the portfolio serves as an important component of the overall liquidity management at the Bank, portions of the portfolio also serve as income producing assets. The size and composition of the portfolio reflects liquidity needs, loan demand and interest income objectives. Portfolio size and composition will be adjusted from time to time. While a significant portion of the portfolio consists of readily marketable securities to address liquidity, other parts of the portfolio may reflect funds invested pending future loan demand or to maximize interest income without undue interest rate risk.

​

Investments are comprised of debt securities and non-marketable equity investments. Securities available-for-sale are carried at fair value. Unrealized gains and losses, net of tax, on securities available-for-sale are reported as a separate component of equity. This balance sheet component changes as interest rates and market conditions change. Unrealized gains and losses are not included in the calculation of regulatory capital.

​

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 $5.5 million at June 30, 2022, and $7.1 million at December 31, 2021. FRBC stock was recorded at $14.9 million at June 30, 2022, and $6.2 million at December 31, 2021.

​

The following tables summarize the amortized cost and fair value of the securities portfolio at June 30, 2022, and December 31, 2021, and the corresponding amounts of gross unrealized gains and losses:

student loans to parents and students. While the program was modified several times before elimination in 2010, FFEL securities are generally guaranteed by the U.S Department of Education (“DOE”) at not less than 97% of the outstanding principal amount of the loans. The guarantee will reduce to 85% if the DOE receives reimbursement requests in excess of 5% of insured loans; reimbursement will drop to 75% if reimbursement requests exceed 9% of insured loans. In addition to the DOE guarantee, total added credit enhancement in the form of overcollateralization and/or subordination amounted to $20.3 million, or 9.29%, of outstanding principal.

​

At June 30, 2022, the Company had no securities issued from any one originator, other than the U.S. Government and its agencies, which individually amounted to over 10% of the Company’s stockholders’ equity.

​

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, 2022, as there was no credit quality deterioration noted. Therefore, no provision for credit losses on securities was recognized for the second quarter of 2022.

​

1 Includes $3.5 million and $38.4 million of Paycheck Protection Program (“PPP”) loans at June 30, 2022 and December 31, 2021, respectively.

​

2 The “Other” segment includes consumer and overdrafts in this table and in subsequent tables within Note 4 - Loans and Allowance for Credit Losses on Loans.

​

​

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 71.0% and 71.6% of the portfolio at June 30, 2022, and December 31, 2021, respectively, and include a mix of owner and non-owner occupied, residential, construction and multifamily loans.

Credit Quality Indicators

​

The Company categorizes loans into credit risk categories based on current financial information, overall debt service coverage, comparison to industry averages, historical payment experience, and current economic trends. This analysis includes loans with outstanding balances or commitments greater than $50,000 and excludes homogeneous loans such as home equity lines of credit and residential mortgages. Loans with a classified risk rating are reviewed quarterly regardless of size or loan type. The Company uses the following definitions for classified risk ratings:

​

Special Mention. 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, 2022 were as follows:

​

The Company had $659,000 and $488,000 in residential real estate loans in the process of foreclosure as of June 30, 2022, and December 31, 2021, 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 were not considered TDRs, if modified prior to January 1, 2022, unless the borrower was experiencing financial difficulty prior to the pandemic.

​

The specific allocation of the allowance for credit losses for TDRs is determined by calculating the present value of the TDR cash flows by discounting the original payment less an assumption for probability of default at the original note’s issue rate, and adding this amount to the present value of collateral less selling costs. If the resulting amount is less than the recorded book value, the Bank either establishes a valuation allowance (i.e., specific reserve) as a component of the allowance for credit losses or charges off the impaired balance if it determines that such amount is a confirmed loss. This method is used consistently for all segments of the portfolio. The allowance for credit losses also includes an allowance based on a loss migration analysis for each loan category on loans and leases that are not individually evaluated for specific impairment. All loans charged-off, including TDRs charged-off, are factored into this calculation by portfolio segment.

There were two TDR loan modifications for an aggregate of $41,000 for the three months ended June 30, 2022 and three TDR loan modifications for an aggregate of $1.1 million for the six months ended June 30, 2022. There was no TDR activity for the three and six months ended June 30, 2021. TDRs are classified as being in default on a case-by-case basis when they fail to be in compliance with the modified terms. There was no TDR default activity for the periods ended June 30, 2022, and June 30, 2021, for loans that were restructured within the prior 12 month period.

Total borrowings | ​ | $ | 178,159 | ​ | $ | 198,876 | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​

The Company enters into deposit sweep transactions where the transaction amounts are secured by pledged securities. These transactions consistently mature overnight from the transaction date and are governed by sweep repurchase agreements. All sweep repurchase agreements are treated as financings secured by U.S. government agencies and collateralized mortgage-backed securities and had a carrying amount of $37.6 million at June 30, 2022, and $50.3 million at December 31, 2021. The fair value of the pledged collateral was $102.6 million at June 30, 2022, and $113.0 million at December 31, 2021. At June 30, 2022, there were no customers with secured balances exceeding 10% of stockholders’ equity.

​

The Company’s borrowings at the FHLBC require the Bank to be a member and invest in the stock of the FHLBC. Total borrowings are generally limited to the lower of 35% of total assets or 60% of the book value of certain mortgage loans. As of June 30, 2022, and December 31, 2021, the Bank had no short-term advances outstanding under the FHLBC. The Bank assumed $23.4 million of long-term FHLBC advances with our ABC Bank acquisition in 2018. The remaining balance of $5.9 million was paid off in full during the second quarter of 2022. FHLB stock held as of June 30, 2022 was valued at $5.5 million, and any potential FHLBC advances were collateralized by loans with a principal balance of $820.3 million, which carried a FHLBC-calculated combined collateral value of $559.3 million. The Company had excess collateral of $479.3 million available to secure borrowings at June 30, 2022.

​

The Company also had $44.5 million of senior notes outstanding, net of deferred issuance costs, as of June 30, 2022 and December 31, 2021. The senior notes were issued in December 2016 with a ten year maturity, and terms include interest payable semiannually at 5.75% for five years. Beginning December 31, 2021, the senior debt began to pay interest at a floating rate, with interest payable quarterly at three month LIBOR plus 385 basis points. The notes are redeemable, in whole or in part, at the option of the Company, beginning with the interest payment date on December 31, 2021, and on any floating rate interest payment date thereafter, at a redemption price equal to 100% of the principal amount of the notes plus accrued and unpaid interest. As of June 30, 2022, and December 31, 2021, unamortized debt issuance costs related to the senior notes were $467,000 and $520,000, respectively, and are included as a reduction of the balance of the senior notes on the Consolidated Balance Sheet. These deferred issuance costs will be amortized to interest expense over the ten year term of the notes and are included in the Consolidated Statements of Income.

​

On February 24, 2020, the Company originated a $20.0 million term note, of which $11.0 million is outstanding as of June 30, 2022, with a correspondent bank. The term note was issued for a three year term at one-month LIBOR plus 175 basis points, requires principal and interest payments quarterly, and the balance of this note is included within Notes Payable and Other Borrowings on the Consolidated Balance Sheet. The Company also has an undrawn line of credit of $30.0 million with a correspondent bank to be used for short-term funding needs; advances under this line can be outstanding up to 360 days from the date of issuance. This line of credit has not been utilized since early 2019.

​

In the second quarter of 2021, we sold and issued $60.0 million in aggregate principal amount of our 3.50% Fixed-to-Floating Rate Subordinated Notes due April 15, 2031 (the “Notes”). The Notes were offered and sold to eligible purchasers in a private offering in reliance on the exemption from the registration requirements of Section 4(a)(2) of the Securities Act of 1933, as amended and the provisions of Regulation D promulgated thereunder. The Company intends to use the net proceeds from the offering for general corporate purposes, which may include, without limitation, the redemption of existing senior debt, common stock repurchases and strategic acquisitions. The Notes bear interest at a fixed annual rate of 3.50%, from and including the date of issuance to but excluding April 15, 2026, payable semi-annually in arrears. From and including April 15, 2026 to, but excluding the maturity date or early redemption date, the interest rate will reset quarterly to an interest rate per annum equal to Three-Month Term SOFR (as defined in the Note) plus 273 basis points, payable quarterly in arrears. As of June 30, 2022, we had $59.3 million of subordinated debentures outstanding, net of deferred issuance costs.

​

Note 8 – Junior Subordinated Debentures

​

The Company issued $25.0 million of cumulative trust preferred securities through a private placement completed by an unconsolidated subsidiary, Old Second Capital Trust II, in April 2007. These trust preferred securities mature in 30 years, but subject to regulatory approval, can be called in whole or in part on a quarterly basis commencing June 15, 2017. The quarterly cash distributions on the securities were fixed at 6.77% through June 15, 2017, and now have a floating rate of 150 basis points over three-month LIBOR. Upon conversion to a floating rate, a cash flow hedge was initiated which resulted in the total interest rate paid on the debt of 4.42% and 4.41% for the quarters ended June 30, 2022 and June 30, 2021, respectively. 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, 2022, and December 31, 2021, the remaining unamortized debt issuance costs related to the junior subordinated debentures were $1,000 and are included as a reduction to the balance of the junior subordinated debentures on the Consolidated Balance Sheet. The remaining deferred issuance costs on the junior subordinated debentures related to the issuance of Old Second Capital Trust II will be amortized to interest expense over the remainder of the 30-year term of the notes and are included in the Consolidated Statements of Income.

​

​

Note 9 – Equity Compensation Plans

​

Stock-based awards are outstanding under the Company’s 2019 Equity Incentive Plan, as amended and restated (the “2019 Plan”). The 2019 Plan was originally approved at the May 2019 annual stockholders’ meeting and authorized 600,000 shares, and at the May 2021 annual stockholders’ meeting, the Company obtained stockholder approval to increase the number of shares of common stock authorized for issuance under the plan by 1,200,000 shares, from 600,000 shares to 1,800,000 shares. Following the approval of the 2019 Plan, no further awards will be granted under any other prior plan.

​

The 2019 Plan authorizes the granting of qualified stock options, non-qualified stock options, restricted stock, restricted stock units, and stock appreciation rights (“SARs”). Awards may be granted to selected directors, officers, employees or eligible service providers under the 2019 Plan at the discretion of the Compensation Committee of the Company’s Board of Directors. As of June 30, 2022, 1,176,029 shares remained available for issuance under the 2019 Plan

​

Under the 2019 Plan, unless otherwise provided in an award agreement, upon the occurrence of a change in control, all stock options and SARs then held by the participant will become fully exercisable immediately if, and all stock awards and cash incentive awards will

become fully earned and vested immediately if, (i) the 2019 Plan is not an obligation of the successor entity following a change in control or (ii) the 2019 Plan is an obligation of the successor entity following a change in control and the participant incurs a termination of service without cause or for good reason following the change in control. Notwithstanding the immediately preceding sentence, if the vesting of an award is conditioned upon the achievement of performance measures, then such vesting will generally be subject to the following: if, at the time of the change in control, the performance measures are less than 50% attained (pro rata based upon the time of the period through the change in control), the award will become vested and exercisable on a fractional basis with the numerator being equal to the percentage of attainment and the denominator being 50%; and if, at the time of the change in control, the performance measures are at least 50% attained (pro rata based upon the time of the period through the change in control), the award will become fully earned and vested immediately upon the change in control.

​

Awards of restricted stock units under the 2019 Plan generally entitle holders to voting and dividend rights upon grant and are subject to forfeiture until certain restrictions have lapsed including employment for a specific period. Awards of restricted stock units under the 2019 Plan are also subject to forfeiture until certain restrictions have lapsed including employment for a specific period, but do not entitle holders to voting rights until the restricted period ends and shares are transferred in connection with the units Generally, restricted stock and restricted stock units granted under the Plans vest three years from the grant date, but the Compensation Committee of the Company’s Board of Directors has discretionary authority to change some terms including the amount of time until the vest date.

​

There were 264,589 and 222,964 restricted stock units issued under the 2019 Plan during the six months ended June 30, 2022 and June 30, 2021, respectively. Compensation expense is recognized over the vesting period of the restricted stock units based on the market value of the award on the issue date. Total compensation cost that has been recorded for the Plan was $1.5 million in the first six months of 2022 and $644,000 for the first six months of 2021.

​

A summary of changes in the Company’s unvested restricted awards for the six months ended June 30, 2022, is as follows:

​

​ | ​ | ​ | ​ | ​ | ​
​ | ​ | June 30, 2022

Note 11 – Regulatory & Capital Matters

​

The Bank is subject to the risk-based capital regulatory guidelines, which include the methodology for calculating the risk-weighted Bank assets, developed by the Office of the Comptroller of the Currency (the “OCC”) and the other bank regulatory agencies. In connection with the current risk-based capital regulatory guidelines, the Bank’s Board of Directors has established an internal guideline requiring the Bank to maintain a Tier 1 leverage capital ratio at or above eight percent (8%) and a total risk-based capital ratio at or above twelve percent (12%). At June 30, 2022, the Bank exceeded those thresholds.

​

At June 30, 2022, the Bank’s Tier 1 capital leverage ratio was 8.94%, a decrease of 64 basis points from December 31, 2021, but is above the 8.00% objective. The Bank’s total capital ratio was 13.25%, a decrease of 21 basis points from December 31, 2021, but also above the objective of 12.00%.

​

Bank holding companies are generally required to maintain minimum levels of capital in accordance with capital guidelines implemented by the Board of Governors of the Federal Reserve System. The general bank and holding company capital adequacy guidelines are shown in the accompanying table, as are the capital ratios of the Company and the Bank, as of June 30, 2022, and December 31, 2021.

​

In July 2013, the U.S. federal banking authorities issued final rules (the “Basel III Rules”) establishing more stringent regulatory capital requirements for U.S. banking institutions, which went into effect on January 1, 2015. The Basel III Rules are applicable to all banking organizations that are subject to minimum capital requirements, including federal and state banks and savings and loan associations, as well as to bank and savings and loan holding companies, other than “small bank holding companies”, which are generally holding companies with consolidated assets of less than $3.0 billion. A detailed discussion of the Basel III Rules is included in Part I, Item 1 of the Company’s Form 10-K for the year ended December 31, 2021, under the heading “Supervision and Regulation.”

​

At June 30, 2022 and December 31, 2021, the Company, on a consolidated basis, exceeded the minimum thresholds to be considered “well capitalized” under current regulatory defined capital ratios.

​

As part of its response to the impact of the COVID-19 pandemic, in the first quarter of 2020, U.S. federal regulatory authorities issued an interim final rule that provided banking organizations that adopted CECL during the 2020 calendar year with the option to delay for two years the estimated impact of CECL on regulatory capital relative to regulatory capital determined under the prior incurred loss methodology, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided during the initial two-year delay (i.e., a five-year transition in total). In connection with our adoption of CECL on January 1, 2020, we elected to utilize the five-year CECL transition. As of June 30, 2022, the capital measures of the Company exclude $2.9 million, which is the modified CECL transition adjustment.

Dividend Restrictions

​

In addition to the above requirements, banking regulations and capital guidelines generally limit the amount of dividends that may be paid by a bank without prior regulatory approval. Under these regulations, the amount of dividends that may be paid in any calendar year is limited to the current year’s profits, combined with the retained profit of the previous two years, subject to the capital requirements described above. As of June 30, 2022, the Bank had capacity to pay dividends of $11.1 million to the Company without prior regulatory approval. 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.

Note 12 – Fair Value Measurements

​

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy established by the Company also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Three levels of inputs that may be used to measure fair value are:

​

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Company has the ability to access as of the measurement date.

​

Level 2: Significant observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data.

​

Level 3: Significant unobservable inputs that reflect a company’s own view about the assumptions that market participants would use in pricing an asset or liability.

​

Transfers between levels are deemed to have occurred at the end of the reporting period. At June 30, 2022 and 2021, there were no transfers between levels.

​

The majority of securities available-for-sale are valued by external pricing services or dealer market participants and are classified in Level 2 of the fair value hierarchy. Both market and income valuation approaches are utilized. Quarterly, the Company evaluates the methodologies used by the external pricing services or dealer market participants to develop the fair values to determine whether the results of the valuations are representative of an exit price in the Company’s principal markets and an appropriate representation of fair value. The Company uses the following methods and significant assumptions to estimate fair value:

​

| ● | Government-sponsored agency debt securities are primarily priced using available market information through processes such as benchmark spreads, market valuations of like securities, like securities groupings and matrix pricing.

| ● | Other government-sponsored agency securities, MBS and some of the actively traded real estate mortgage investment conduits and collateralized mortgage obligations are priced using available market information including benchmark yields, prepayment speeds, spreads, volatility of similar securities and trade date.

| ● | State and political subdivisions are largely grouped by characteristics (e.g., geographical data and source of revenue in trade dissemination systems). Because some securities are not traded daily and due to other grouping limitations, active market quotes are often obtained using benchmarking for like securities.

| ● | Auction rate securities are priced using market spreads, cash flows, prepayment speeds, and loss analytics. Therefore, the valuations of auction rate asset-backed securities are considered Level 2 valuations.

| ● | Asset-backed collateralized loan obligations were priced using data from a pricing matrix supported by our bond accounting service provider and are therefore considered Level 2 valuations.

| ● | Annually every security holding is priced by a pricing service independent of the regular and recurring pricing services used. The independent service provides a measurement to indicate if the price assigned by the regular service is within or outside of a reasonable range. Management reviews this report and applies judgment in adjusting calculations at year end related to securities pricing.

| ● | Residential mortgage loans available for sale in the secondary market are carried at fair market value. The fair value of loans held-for-sale is determined using quoted secondary market prices.

| ● | Lending related commitments to fund certain residential mortgage loans, e.g., residential mortgage loans with locked interest rates to be sold in the secondary market and forward commitments for the future delivery of mortgage loans to third party investors, as well as forward commitments for future delivery of MBS are considered derivatives. Fair values are estimated based on observable changes in mortgage interest rates including prices for MBS from the date of the commitment and do not typically involve significant judgments by management.

| ● | The fair value of mortgage servicing rights is based on a valuation model that calculates the present value of estimated net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income to derive the resultant value. The Company is able to compare the valuation model inputs, such as the discount rate, prepayment speeds, weighted average delinquency and foreclosure/bankruptcy rates to widely available published industry data for reasonableness.

| ● | Interest rate swap positions, both assets and liabilities, are based on valuation pricing models using an income approach reflecting readily observable market parameters such as interest rate yield curves.

| ● | The fair value of impaired loans with specific allocations of the allowance for credit losses is essentially based on recent real estate appraisals or the fair value of the collateralized asset. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are made in the appraisal process by the appraisers to reflect differences between the available comparable sales and income data. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value.

| ● | Nonrecurring adjustments to certain commercial and residential real estate properties classified as OREO are measured at fair value, less costs to sell. Fair values are based on third party appraisals of the property, resulting in a Level 3 classification, or an executed pending sales contract. In cases where the carrying amount exceeds the fair value, less costs to sell, an impairment loss is recognized.

​

In addition to the above, Level 3 fair value measurement included $13.1 million for state and political subdivisions representing various local municipality securities at June 30, 2022. These securities were classified as securities available-for-sale, and were valued using a discount based on market spreads of similar assets, but the liquidity premium was an unobservable input. The state and political subdivisions securities balance in Level 3 fair value at June 30, 2021, was $5.0 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, 2022, and December 31, 2021, respectively, the following tables provide the level of valuation assumptions used to determine each valuation and the carrying value of the related assets:

​

​

1 Represents carrying value and related write-downs of loans for which adjustments are substantially based on the appraised value of collateral for collateral-dependent loans, which had a carrying amount of $42.4 million and a valuation allowance of $14.2 million resulting in an increase of specific allocations within the allowance for credit losses on loans of $8.8 million for the six months ended June 30, 2022.

2 OREO is measured at fair value, less costs to sell, and had a net carrying amount of $1.6 million at June 30, 2022, which is made up of the outstanding balance of $2.7 million, net of a purchase accounting adjustment of $131,000 and a valuation allowance of $920,000.

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 13 – Fair Values of Financial Instruments

​

The estimated fair values approximate carrying amount for all items except those described in the following table. Securities available-for-sale fair values are based upon market prices or dealer quotes, and if no such information is available, on the rate and term of the security. The carrying value of FHLBC stock approximates fair value as the stock is nonmarketable and can only be sold to the FHLBC or another member institution at par. FHLBC stock is carried at cost and considered a Level 2 fair value. The fair value of loans and leases at June 30, 2022 and December 31, 2021, was estimated on an exit price basis incorporating discounts for credit, liquidity and marketability factors. The fair value of time deposits was estimated using discounted future cash flows at current rates offered for deposits of similar remaining maturities. The fair values of borrowings were estimated based on interest rates available to the Company for debt with similar terms and remaining maturities. The fair value of off balance sheet volume was not considered material.

​

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

Note 14 – Derivatives, Hedging Activities and Financial Instruments with Off-Balance Sheet Risk

​

Risk Management Objective of Using Derivatives

​

The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s loan portfolio.

​

Cash Flow Hedges of Interest Rate Risk

​

The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. In December of 2019, the Company also executed a loan pool hedge of $50 million to convert variable rate loans to a fixed rate index for a five year term.

​

For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in Accumulated Other Comprehensive Income and subsequently reclassified into interest income/expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will

35

Table of Contents

Old Second Bancorp, Inc. and Subsidiaries

Notes to Consolidated Financial Statements

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

be reclassified to interest expense as interest payments are received on the Company’s variable-rate borrowings. During the next twelve months, the Company estimates that an additional $101,000 will be reclassified as an increase to interest income and an additional $117,000 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, 2022, was designated as a cash flow hedge of certain junior subordinated debentures and was determined to be fully effective during the period presented. As such, no amount of ineffectiveness has been included in net income. Therefore, the aggregate fair value of the swap is recorded in other liabilities with changes in fair value recorded in other comprehensive income, net of tax. The amount included in other comprehensive income would be reclassified to current earnings should all or a portion of the hedge no longer be considered effective. The Company expects the hedge to remain fully effective during the remaining term of the swap. The Bank will pay the counterparty a fixed rate and receive a floating rate based on three month LIBOR. The trust preferred securities 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 also has interest rate derivative positions to assist with risk management that are not designated as hedging instruments. These derivative positions relate to transactions in which the Bank enters an interest rate swap with a client while at the same time entering into an offsetting interest rate swap with another financial institution. The Bank held $3.0 million of cash collateral and $180,000 of cash collateral related to one correspondent financial institution to cover the loan pool hedge mark to market valuation at June 30, 2022 and December 31, 2021, respectively. The Bank had $1.8 million and $17.2 million of cash collateral held by one correspondent financial institution to support interest rate swap activity and no investment securities were required to be pledged to any correspondent financial institution at June 30, 2022 and December 31, 2021, respectively. At June 30, 2022, the notional amount of non-hedging interest rate swaps was $147.8 million with a weighted average maturity of 3.6 years. At December 31, 2021, the notional amount of non-hedging interest rate swaps was $165.0 million with a weighted average maturity of 3.9 years. The Bank offsets derivative assets and liabilities that are subject to a master netting arrangement.

​

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 $581,000 as of June 30, 2022, and $1.9 million as of June 30, 2021. The amount of the loss reclassified from AOCI to interest expense on the income statement was $16,000 and $26,000 for the six months ended June 30, 2022, and June 30, 2021, respectively.

​

​

Credit-risk-related Contingent Features

​

For derivative transactions involving counterparties who are lending customers of the Company, the derivative credit exposure is managed through the normal credit review and monitoring process, which may include collateralization, financial covenants and/or financial guarantees of affiliated parties. Agreements with such customers require that losses associated with derivative transactions receive payment priority from any funds recovered should a customer default and ultimate disposition of collateral or guarantees occur.

​

Credit exposure to broker/dealer counterparties is managed through agreements with each derivative counterparty that require collateralization of fair value gains owed by such counterparties. Some small degree of credit exposure exists due to timing differences between when a gain may occur and the subsequent point in time that collateral is delivered to secure that gain. This is monitored by the Company and procedures are in place to minimize this exposure. Such agreements also require the Company to collateralize counterparties in circumstances wherein the fair value of the derivatives result in loss to the Company.

​

Other provisions of such agreements include the definition of certain events that may lead to the declaration of default and/or the early termination of the derivative transaction(s):

| ● | If the Company either defaults or is capable of being declared in default on any of its indebtedness (exclusive of deposit obligations), then the Company could also be declared in default on its derivative obligations.

| ● | If a merger occurs that materially changes the Company's creditworthiness in an adverse manner.

| ● | If certain specified adverse regulatory actions occur, such as the issuance of a Cease and Desist Order, or citations for actions considered Unsafe and Unsound or that may lead to the termination of deposit insurance coverage by the FDIC.

​

The Bank also issues letters of credit, which are conditional commitments that guarantee the performance of a customer to a third party. The credit risk involved and collateral obtained in issuing letters of credit are essentially the same as that involved in extending loan commitments to our customers. In addition to customer related commitments, the Company is responsible for letters of credit commitments that relate to properties held in OREO. The following table represents the Company’s contractual commitments due to letters of credit as of June 30, 2022, and December 31, 2021.

​

As of June 30, 2022, the Company evaluated current market conditions, including any impacts related to COVID-19, market interest rate changes, and unused line of credit utilization trends during the second quarter of 2022, and based on that analysis under the CECL methodology, the Company determined credit losses related to unfunded commitments totaled $3.4 million, excluding a $1.3 million purchase accounting adjustment on unfunded commitments recorded from our West Suburban acquisition, which is being accreted to interest income over the estimated life of the unused commitments. The resultant decrease in the ACL for unfunded commitments of $1.0 million for the second quarter of 2022, compared to the prior quarter end, is primarily related to a $780,000 decrease in the commercial unfunded commitments funding rate assumptions based on our analysis of the last 12 months of utilization, as well as accretion of $223,000 to interest income of the purchase accounting adjustment. 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.

Business Overview

​

The Company is a bank holding company headquartered in Aurora, Illinois. Through our wholly-owned subsidiary bank, Old Second National Bank, a national banking organization also headquartered in Aurora, Illinois, we offer a wide range of financial services through our 51 banking centers located in Cook, DeKalb, DuPage, Kane, Kendall, LaSalle and Will counties in Illinois. These banking centers offer access to a full range of traditional retail and commercial banking services including treasury management operations as well as fiduciary and wealth management services. We focus our business on establishing and maintaining relationships with our clients while maintaining a commitment to provide for the financial services needs of the communities in which we operate. We emphasize relationships with individual customers as well as small to medium-sized businesses throughout our market area. We also have extensive wealth management services, which includes a registered investment advisory platform in addition to trust administration and trust services related to personal and corporate trusts and employee benefit plan administration services.

​

Merger with West Suburban Bancorp, Inc.

​

On December 1, 2021, we completed our merger with West Suburban Bancorp, Inc. (“West Suburban”), the holding company for West Suburban Bank. Under the terms of the merger agreement, each share of West Suburban common stock was converted into 42.413 shares of our common stock and $271.15 in cash. Total cash and stock consideration paid was approximately $295.2 million. With the acquisition of West Suburban, we acquired 34 branches in DuPage, Kane, Kendall and Will counties in Illinois. The transaction is discussed in more detail in Note 2 to our Consolidated Financial Statements included in this report.

​

As we continue to consolidate operations, five branches designated as held for sale with a net book value of $9.6 million are reported within fixed assets at June 30, 2022. During the six months ended June 30, 2022, we sold five branches, resulting in $1.4 million of net gains on sale, after closing costs.

​

COVID-19 Update

​

Our historically careful underwriting practices and diverse loan portfolio has helped minimize the adverse impact of the pandemic on the Company. In addition, the combination of the vaccine rollout, government stimulus payments, and reduced spending during the pandemic are likely contributing factors mitigating the impact of the pandemic on our business, financial condition, results of operations, and our customers as of June 30, 2022. While vaccine availability and uptake has increased, the longer term macro-economic effects on global supply chains, inflation, labor shortages and wage increases continue to impact many industries. 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 new COVID-19 cases, hospitalizations and deaths leading to additional government imposed restrictions; refusals to receive the vaccine along with concerns related to new strains of the virus; supply chain issues remaining unresolved longer than anticipated; labor shortages and wage increases continuing to impact many industries; consumer confidence and spending falls; and rising geopolitical tensions. Given the ongoing and dynamic nature of the circumstances surrounding the pandemic, it is difficult to predict its future adverse financial impact to the Company, although we expect to continue to be impacted by the pandemic throughout the remainder of 2022.

Results of Operation and Financial Condition

​

We continue to monitor the impact of the COVID-19 pandemic on our results of operations and financial condition. For the year ended December 31, 2020, we determined it prudent to increase our allowance for credit losses to $33.9 million, driven by both our adoption of the Current Expected Credit Losses (“CECL”) methodology and the expected impact of the COVID-19 pandemic and market interest rate reductions in anticipation of continued market risk and uncertainty. In 2021, due to the lack of significant net charge-offs projected with the 2020 forecast, and a more favorable forecast for the estimated life of loans, we reversed $9.5 million of our legacy allowance for credit losses, but recorded $12.1 million of Day One credit marks to the allowance for credit losses, as well as $12.2 million of Day Two adjustments on non-purchase credit deteriorated life of loan loss estimates, each stemming from the West Suburban acquisition. During the first six months of 2022, we recorded $1.3 million of provision for credit losses on loans primarily due to loan growth as well as our assessment of loan metrics and nonperforming loan trends. In addition, we also recorded a reduction of $780,000 in our allowance for credit losses on unfunded commitments, primarily due to a review of credit line utilization rates. These adjustments resulted in a net provision for credit losses expense of $550,000 in the second quarter of 2022.

​

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, 2022 and December 31, 2021, we had $86.3 million of goodwill. At November 30, 2021, we performed our recurring annual review for any goodwill impairment. We determined no goodwill impairment existed, however, 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.

​

Lending Operations and Accommodations to Borrowers

​

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. During 2020 and 2021, we executed 509 of these deferrals on loan balances of $242.7 million. As of June 30, 2022, all COVID-related loan deferrals had resumed payments or paid off.

​

During 2020 and 2021, as part of the SBA Paycheck Protection Program (“PPP”), we processed 1,320 PPP loan applications, representing a total of $199.0 million, and we acquired $20.8 million PPP loans from our acquisition of West Suburban. We started the application process for loan forgiveness for PPP loans in October 2020, and we continued to receive funds for forgiven loans from both the first and second round of PPP loans through June 2022. As of June 30, 2022, we had 31 loans, which totaled $3.5 million, still outstanding under the PPP program. We expect the application process for loan forgiveness to continue through the third quarter of 2022, with funds to be received from the SBA for the forgiven loans through the remainder of 2022.

​

Capital and Liquidity

As of June 30, 2022, 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. However, to date, due in part to federal government stimulus funds received by our customers, as well as a higher volume of loan paydowns than periods prior to COVID-19, our liquidity has increased.

Financial Overview

​

Net income for the second quarter of 2022 was $12.2 million, or $0.27 per diluted share, compared to $8.8 million, or $0.30 per diluted share, for the second quarter of 2021. The increase was primarily due to our acquisition of West Suburban, which resulted in growth in net interest income and noninterest income, partially offset by higher noninterest expense, which included $2.1 million in acquisition-related costs net of gain on sale of branches in the second quarter of 2022. Adjusted net income, a non-GAAP financial measure that

excludes merger-related costs, net of gains on branch sales, was $13.8 million for the second quarter of 2022. See the discussion entitled “Non-GAAP Financial Measures” on page 42, as well as the table below, which provides a reconciliation of this non-GAAP measure to the most comparable GAAP equivalents.

​

The following provides an overview of some of the factors impacting our financial performance for the three month period ended June 30, 2022, compared to the like period ended June 30, 2021:

​

| ● | Net interest and dividend income was $45.3 million for the second quarter of 2022, compared to $22.0 million for the second quarter of 2021. Growth in interest and dividend income in the second quarter of 2022 was primarily due to our acquisition of West Suburban resulting in additional loan and securities income.

​

| ● | We recorded a net provision for credit losses of $550,000 in the second quarter of 2022, driven by a $1.3 million increase in the allowance for credit losses on loans due to loan growth in the portfolio, partially offset by a $780,000 reduction in our allowance for unfunded commitments. We recorded a $3.5 million release of provision expense in the second quarter of 2021.

​

| ● | Noninterest income was $9.2 million for the second quarter of 2022, compared to $7.9 million for the second quarter of 2021, an increase of $1.3 million, or 16.3%. Contributing to the increase was growth in service charges on deposits and card related income resulting primarily from the West Suburban acquisition and resultant additional fee income. These increases were partially offset by a $262,000 net loss on sales of mortgage loans in the second quarter of 2022, compared to a $1.9 million net gain in the second quarter of 2021.

​

| ● | Noninterest expense was $37.2 million for the second quarter of 2022, compared to $21.4 million for the second quarter of 2021, an increase of $15.8 million, or 74.0%. Contributing to the increase was growth in salaries and employee benefits and occupancy, furniture and equipment expenses in the first quarter of 2022, primarily stemming from the additional employees and branches due to the West Suburban acquisition. In addition, we recorded $3.3 million of acquisition-related costs in the second quarter of 2022, primarily within computer and data processing, salaries and employee benefits, and other expense related to the West Suburban acquisition.

​

| ● | We had a provision for income tax expense of $4.4 million for the second quarter of 2022, compared to a provision for income tax expense of $3.2 million for the second quarter of 2021. The increase in tax expense for the second quarter of 2022 was due to an increase in pre-tax income, compared to the year over year quarter.

​

| ● | Our community-focused banking franchise experienced growth of $204.3 million in total loans at June 30, 2022, compared to the year ended December 31, 2021, and an increase of $1.72 billion in total loans compared to the second quarter of 2021, as we acquired $1.50 billion of loans in the West Suburban acquisition. We believe we are positioned for continued loan growth as we continue to serve our customers’ needs in a competitive economic environment. 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 seeking to ensure the safety and soundness of our Bank, our customers and our employees during the COVID-19 pandemic.

| ● | Nonaccrual loans decreased $5.8 million as of June 30, 2022, compared to December 31, 2021, due to the upgrade or payoff of various credits in the first and second quarter of 2022. Nonperforming loans as a percent of total loans was 1.2% as of June 30, 2022, compared to 1.3% as of December 31, 2021, and 1.2% at June 30, 2021. Classified assets increased to $103.2 million as of June 30, 2022, which is $28.4 million, or 38.0% more than December 31, 2021, and $61.1 million more than June 30, 2021, due to the West Suburban acquisition in late 2021.

Critical Accounting Estimates

​

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 Estimates” in our Annual Report on Form 10-K for the year ended December 31, 2021. 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 2021 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, adjusted net income, adjusted basic and diluted earnings per share, our adjusted efficiency ratio, and our tangible common equity to tangible assets ratio. 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, 2022 and 2021

Our income before taxes was $16.7 million in the second quarter of 2022 compared to $12.0 million in the second quarter of 2021. This increase in pretax income was primarily due to a $23.2 million increase in interest and dividend income, and a $1.3 million increase in noninterest income, primarily due to the addition of West Suburban loan, securities and fee income in the second quarter of 2022. These increases were partially offset by a $15.8 million increase in noninterest expense, primarily due to an increase in salaries and employee benefits, occupancy, furniture and equipment expense, computer and data processing expense, other expense, and amortization of core deposit intangible. The majority of these increases were due to the inclusion of operating costs of the legacy West Suburban staff and branches, as well as $3.3 million of West Suburban acquisition-related costs in the second quarter of 2022, primarily within computer and data processing. Our net income was $12.2 million, or $0.27 per diluted share, for the second quarter of 2022, compared to net income of $8.8 million, or $0.30 per diluted share, for the second quarter of 2021.

Net interest and dividend income was $45.3 million in the second quarter of 2022, compared to $22.0 million in the second quarter of 2021. The $23.3 million increase was primarily driven by growth in all interest and dividend income categories due to West Suburban

related loan and securities income being reflected. In addition we experienced a decrease in interest expense in the second quarter of 2022, compared to the second quarter of 2021, primarily due to a reduction in deposit interest rates offset by increased balances from West Suburban, decreased outstanding balances of notes payable and other borrowings, and a decrease in the rate paid on our senior notes during 2022, as the interest rate payable on these notes became floating as of January 1, 2022, at three month LIBOR plus 385 basis points, compared to the prior 5.75% fixed rate.

Average loans, including loans held for sale, increased $1.58 billion in the second quarter of 2022, compared to the second quarter of 2021, primarily from $1.50 billion of average loans acquired in our acquisition of West Suburban. Also contributing to the increase was $104.3 million in average loan growth during the second quarter of 2022, less PPP loans forgiven or repaid and loan paydowns.

​

Six months ended June 30, 2022 and 2021

​

Our income before taxes was $33.1 million for the six months ended June 30, 2022 compared to $28.1 million for the six months ended June 30, 2021. This increase in pretax income was primarily due to a $41.1 million increase in interest and dividend income, and a $3.5 million increase in noninterest income, as West Suburban loan, securities and fee income are included in the six months ended June 30, 2022. These increases were partially offset by a $32.4 million increase in noninterest expense, primarily due to an increase in salaries and employee benefits, occupancy, furniture and equipment expense, computer and data processing expense, other expense, and amortization of core deposit intangible. The majority of these increases were due to the inclusion of operating costs of the legacy West Suburban staff and branches, as well as $8.8 million of West Suburban acquisition-related costs in the first six months of 2022, primarily within computer and data processing. Our net income was $24.3 million, or $0.54 per diluted share, for the six months ended June 30, 2022, compared to net income of $20.7 million, or $0.70 per diluted share, for the same period of 2021.

Net interest and dividend income was $86.5 million for the six months ended June 30, 2022, compared to $45.5 million for the same period of 2021. The $41.0 million increase was primarily driven by growth in all interest and dividend income categories due to West Suburban related loan and securities income being reflected. This increase was partially offset by a $136,000 increase in interest expense for the six months ended June 30, 2022, compared to the same period of 2021, primarily due to a full period of interest expense on the April 2021 issuance of subordinated debt, as well as higher average balances of deposits from the West Suburban acquisition, partially offset by a decrease in outstanding balances of notes payable and a decrease in the rate paid on our senior notes during 2022, as the interest rate payable on these notes became floating as of January 1, 2022, at three month LIBOR plus 385 basis points, compared to the prior 5.75% fixed rate.

​

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, 2022 and 2021

​

Our net interest and dividend income increased by $23.3 million to $45.3 million, for the second quarter of 2022, from $22.0 million for the second quarter of 2021. This increase was primarily attributable to a $23.2 million increase in total interest and dividend income due to the acquisition of West Suburban in December 2021. In addition we experienced a decrease in interest expense in the second quarter of 2022, compared to the second quarter of 2021, primarily due to a reduction in deposit interest rates offset by increased balances from West Suburban, decreased outstanding balances of notes payable and other borrowings, and a decrease in the rate paid on our senior notes during 2022, as the interest rate payable on these notes became floating as of January 1, 2022, at three month LIBOR plus 385 basis points, compared to the prior 5.75% fixed rate.

​

Average earning assets for the second quarter of 2022 totaled $5.75 billion, a decrease of $115.0 million, or 2.0%, compared to the first quarter of 2022, and an increase of $2.69 billion, or 88.2%, compared to the second quarter of 2021. Average interest earning deposits with financial institutions totaled $426.8 million for the second quarter of 2022, a decrease of $208.5 million, compared to the first quarter of 2022, and a decrease of $72.7 million compared to the second quarter of 2021. The yield on average interest earning deposits was 73

Table of Contents

basis points for the second quarter of 2022, an increase of 56 basis points from the first quarter of 2022, and an increase of 62 basis points from the second quarter of 2021. Interest income on securities increased year over year, primarily due to growth in volumes and higher interest rates. Total average securities for the second quarter of 2022 decreased $15.8 million from the first quarter of 2022, and increased $1.28 billion from the second quarter of 2021. The increase in our average securities year over year was primarily due to the $1.07 billion in securities acquired in our acquisition of West Suburban. The yield on average securities increased to 1.89% for the second quarter of 2022, compared to 1.54% for the first quarter of 2022 and decreased from 2.24% for the second quarter of 2021. Total average loans, including loans held-for-sale, totaled $3.51 billion in the second quarter of 2022, an increase of $104.3 million from the first quarter of 2022, and an increase of $1.58 billion from the second quarter of 2021. The rise in average loan balances year over year was primarily due to the $1.50 billion loan portfolio acquired in our acquisition of West Suburban, as well as loan growth of $108.0 million in the second quarter of 2022. This rise in loan volumes resulted in an increase in loan interest and fee income of $17.4 million in the year over year period. For the second quarter of 2022, the yield on average loans increased to 4.37%, compared to 4.34% for the first quarter of 2022, and 4.33% for the second quarter of 2021.

​

Average interest bearing liabilities decreased $58.7 million, or 1.6%, in the second quarter of 2022, compared to the first quarter of 2022, and increased $1.64 billion compared to the second quarter of 2021. The year over year increase was primarily driven by a $1.68 billion increase in interest bearing deposits primarily due to our acquisition of West Suburban, as well as continued deposit activity of our legacy customers, offset by a $33.2 million decrease in securities sold under repurchase agreements and a $9.1 million decrease in notes payable and other borrowings. The linked quarter decrease was primarily the result of maturing higher cost time deposits and declines in money market accounts. The cost of interest bearing liabilities for the second quarter of 2022 remained consistent with the linked period, and decreased 24 basis points from the second quarter of 2021. Growth in our average noninterest bearing demand deposits of $1.11 billion 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 0.15% for both the second and first quarters of 2022, and 0.31% for the second quarter of 2021.

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 interest earning deposits with financial institutions in 2020 and 2021 stemming from federal stimulus funds received and PPP loan forgiveness, we had no average other short-term borrowings, which typically consist of FHLBC advances, in the first and second quarters of 2022 or the second quarter of 2021. As of June 30, 2022, we paid off our long-term FHLBC advance of $5.9 million and notes payable and other borrowings now consists of $11.0 million outstanding on a term note with a correspondent bank originated in the first quarter of 2020.

​

Our net interest margin (GAAP) increased 31 basis points to 3.16% for the second quarter of 2022, compared to 2.85% for the first quarter of 2022, and increased 28 basis points compared to 2.88% for the second quarter of 2021. Our net interest margin (TE) increased 30 basis points to 3.18% for the second quarter of 2022, compared to 2.88% for the first quarter of 2022, and increase 25 basis points compared to 2.93% for the second quarter of 2021. The increase year over year was due primarily to the increasing 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 elevated liquidity on our balance sheet.

​

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.

​

Six months ended June 30, 2022 and 2021

​

Our net interest and dividend income increased by $41.0 million, to $86.5 million for the six months ended June 30, 2022, compared to $45.5 million for the six months ended June 30, 2021. This increase was attributable to a $41.1 million increase in total interest income primarily from the acquisition of West Suburban as well as general loan growth, partially offset by a $136,000 increase in interest expense for the six months ended June 30, 2022, compared to the six months ended June 30, 2021. Increased balances on interest earning assets related to the West Suburban acquisition drove the increase in net interest income, along with the reduction in the cost of interest bearing deposits, despite lower yields on interest earning assets and the increased average balance of subordinated debt.

Table of Contents

​

Average earning assets for the six months ended June 30, 2022 were $5.81 billion, an increase of $2.82 billion, or 94.4%, compared to the six months ended June 30, 2021. The yield on average earning assets for the six months ended June 30, 2022 was 3.18%, compared to 3.40% for the six months ended June 30, 2021. Total average loans, including loans held-for-sale, totaled $3.46 billion for the six months ended June 30, 2022, an increase of $1.48 billion, compared to the six months ended June 30, 2021. The increase in average loan balances, partially offset by market interest rate reductions, resulted in a $31.6 million increase in loan interest income for the six months ended June 30, 2022, compared to the like period in 2021. For the six months ended June 30, 2022, yields on average securities decreased by 63 basis points and yields on average loans decreased by five basis points, each as compared to the six months ended June 30, 2021, due primarily to the addition of the lower yielding legacy West Suburban security and loan portfolios in late 2021, as well as the timing of rate resets on loans and securities as interest rates began to rise in 2022, compared to 2021. Average interest earning deposits with financial institutions increased $100.5 million in the six months ended June 30, 2022, compared to the prior year like period driven primarily by the acquisition of West Suburban, as well as remaining federal stimulus funds received by our depositors.

​

Average interest bearing liabilities increased $1.70 billion, or 92.3%, in the six months ended June 30, 2022, compared to the six months ended June 30, 2021. The increase was primarily due to the acquisition of West Suburban in late 2021 resulting in an increase of $2.27 billion of interest earning deposits. In addition, average subordinated debt increased $31.0 million, due to the $60.0 million subordinated note issuance on April 6, 2021, as discussed above. Partially offsetting this increase was a $6.7 million decrease in average notes payable and other borrowings. Average noninterest bearing deposits increased $1.13 billion in the six months ended June 30, 2022 compared to the six months ended June 30, 2021, due to the acquisition of West Suburban, as well as remaining federal stimulus funds received from our depositors. The cost of interest bearing liabilities decreased 21 basis points, to 24 basis points, for the six months ended June 30, 2022, from 45 basis points for the six months ended June 30, 2021.

​

Our net interest margin (GAAP) for the six months ended June 30, 2021 was 3.00% compared to 3.07% for the six months ended June 30, 2022, reflecting a decrease of seven basis points. Our net interest margin (TE) for the six months ended June 30, 2022 was 3.03% compared to 3.12% for the six months ended June 30, 2021, a decrease of nine basis points. The decrease in net interest margin for the six months ended June 30, 2022, compared to the six months ended June 30, 2021, was primarily due to the addition of the lower yielding legacy West Suburban security and loan portfolios in late 2021. 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.

​

The following tables set 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 2022 and 2021 to compare returns more appropriately on tax-exempt loans and securities to other earning assets.

In addition, wealth management income decreased $192,000 from the linked quarter due to a decline in assets under management as a result of global stock market losses. These decreases were partially offset by increases in card related income of $398,000 and service charges on deposits of $254,000 in the second quarter of 2022, compared to the first quarter of 2022.

The increase in noninterest income in the second quarter of 2022, compared to the second quarter of 2021, is primarily due to a $1.3 million increase in card related income, a $1.1 million increase in service charges on deposits, a $117,000 increase in wealth management fees, and a $347,000 increase in other income, each stemming from the inclusion of West Suburban activity in 2022. Partially offsetting these increases was a $1.2 million decline in residential mortgage banking revenue, due to a decrease in mortgage origination volume in the second quarter of 2022, as well as changes in interest rates effecting the mortgage banking derivative, and a $351,000 decrease in the cash surrender value of BOLI, due to market interest rate fluctuations.

Noninterest income increased $3.5 million, or 18.0%, for the six months ended June 30, 2022 compared to the six months ended June 30, 2021. This increase was primarily driven by a $2.4 million increase in card related income, a $2.0 million increase in service charges on deposits, a $664,000 increase in wealth management fees, and a $766,000 increase in other income, each stemming from the inclusion of West Suburban related activity in our results for the six months ended June 30, 2022. Partially offsetting these increases was a $1.8 million decline in mortgage banking revenue year over year, comprised primarily of a $4.4 million decrease in net gain on sales of mortgage loans, partially offset by a $3.0 million mark to market gain on MSRs, both due to the increasing interest rate environment, and a $561,000 decline in the cash surrender value of BOLI.

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, OREO expenses and merger-related costs, net of gain on branch sales, 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” starting on page 52 for a reconciliation of this non-GAAP measure to the most comparable GAAP equivalent.

Noninterest expense for the second quarter of 2022 decreased $1.0 million, or 2.6%, compared to the first quarter of 2022, and increased $15.8 million, or 74.1%, compared to the second quarter of 2021. The linked quarter decrease was primarily attributable to $3.3 million of West Suburban acquisition-related costs for the second quarter of 2022, compared to $5.6 million for the first quarter of 2022. These acquisition-related costs included a $3.2 million decrease in computer and data processing expense in the second quarter of 2022, primarily due to acquisition-related core system conversion costs, and a $489,000 decrease in other expense due to ancillary teller and mobile banking systems conversion costs occurring in the first quarter of 2022. Occupancy, furniture and equipment costs also decreased $850,000 in the second quarter of 2022, compared to the prior quarter, due to net gains on branch sales during the quarter. These decreases were partially offset by a $1.4 million increase in salaries and employee benefits, largely the result of bonuses paid to non-officer employees for efforts during the acquisition and conversion period, and a $523,000 increase in card related expense, due to the growth in customer transactions and related volume charges, as well as certain credits recorded in the first quarter of 2022.

The year over year increase in noninterest expense is primarily attributable to an $8.4 million increase in salaries and employee benefits, a $2.7 million increase in computer and data processing expense, a $2.0 million increase in other expense, and a $743,000 increase in occupancy, furniture and equipment expense. Salaries and officer incentive increased $6.6 million and $468,000, respectively, in the second quarter of 2022, compared to the like quarter of 2021, primarily due to additional employees from our acquisition of West Suburban, as well as growth in our commercial lending team. Employee benefits expense increased $1.4 million in the second quarter of

2022, compared to the second quarter of 2021, due to increases stemming from additional employees from our acquisition of West Suburban, and increases in employee insurance costs as more employees returned to more routine medical appointments, many of which were on hold during the COVID-19 pandemic in 2020 and part of 2021. The increase in occupancy, furniture and equipment expense year over year was due to the addition of 34 West Suburban branches in late 2021. The increase in computer and data processing expense was primarily due to core system conversion costs relating to the West Suburban acquisition. Finally, the increase in other expense was due primarily to growth in net teller banking and bill paying fees of $623,000, which was due to acquisition-related costs in the second quarter of 2022, as well as the impact of a quarter of other expense from the inclusion of West Suburban activity.

​

Noninterest expense for the six months ended June 30, 2022, increased $32.4 million, or 75.0%, compared to the six months ended June 30, 2021, primarily due to an increase in salaries and employee benefits, occupancy, furniture and equipment, computer and data processing, and other expenses, which increases primarily resulted from our acquisition of West Suburban in December 2021. Salaries and employee benefits increased $14.9 million largely from the additional employees from West Suburban, as well as incentives and merit increases effective in the second quarter of 2022. Occupancy, furniture and equipment increased $2.0 million or 41.4% due to additional facilities acquired with our acquisition of West Suburban, net of gains from the sale of overlapping branches. Computer and data processing increased $7.7 million, or 294.9%, primarily related to costs of operating multiple systems prior to conversion as well as data conversion costs. Other expense increased $4.6 million or 79.2% primarily from a $2.4 million increase to net teller and bill paying expense, and $931,000 of other acquisition-related costs. In addition, FDIC insurance increased $719,000 due to our increased asset size, as well as the absence of assessment credits fully utilized in the 2021 year to date period. Amortization of core deposit intangible increased $1.1 million for the six months ended June 30, 2022, compared to the prior year like period, due to the West Suburban acquisition. Finally, consulting and management fees increased $472,000 due to $572,000 of acquisition-related costs and general ledger reclasses in the first six months of 2022.

Income Taxes

​

We recorded income tax expense of $4.4 million for the second quarter of 2022 on $16.7 million of pretax income, compared to income tax expense of $4.4 million on $16.4 million of pretax income in the first quarter of 2022, and income tax expense of $3.2 million on $12.0 million of pretax income in the second quarter of 2021. Our effective tax rate was 26.6% in the second quarter of 2022, 26.9% for the first quarter of 2022, and 26.3% for the second quarter of 2021.

We recorded income tax expense of $8.9 million on $33.1 million of pretax income for the six months ended June 30, 2022, compared to income tax expense of $7.4 million on $28.1 million of pretax income in the like 2021 period. The effective tax rate was 26.7% and 26.3% for the second quarter of 2022 and the second quarter of 2021, respectively.

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, 2022. We had no valuation reserve on the deferred tax assets as of June 30, 2022.

Financial Condition

​

Total assets decreased $206.6 million to $6.01 billion at June 30, 2022, from $6.21 billion at December 31, 2021, due primarily to a net decrease in cash and cash equivalents of $470.7 million, offset by increases of $203.2 million in net loans, $40.8 million in securities available-for-sale, and $26.4 million in deferred tax assets. The decrease in cash and cash equivalents was primarily due to the use of cash in the abovementioned asset increases, as well as the decrease in customer deposits of $123.4 million and loan growth. We continue to actively assess potential investment opportunities to utilize our excess liquidity. Total deposits were $5.3 billion at June 30, 2022, a decrease of $123.4 million from December 31, 2021, primarily due to seasonal decreases of municipal deposits, and to a lesser extent declines in interest bearing demand accounts, savings, money market, NOW, and time deposits in 2022.

​

Securities available-for-sale increased $40.8 million as of June 30, 2022, compared to December 31, 2021, and increased $1.15 billion compared to June 30, 2021. The increase in the portfolio during the second quarter of 2022 was driven by the purchase of $9.7 million of states and political subdivisions, $8.5 million of collateralized mortgage obligations, $3.7 million of asset-backed securities, and $14.0 million of collateralized loan obligations. These purchases were partially offset by $76.1 million of calls, maturities, sales and paydowns during the second quarter of 2022, and an unrealized mark to market loss adjustment of $40.5 million and net premium amortization of $1.5 million. We continue to seek to position our portfolio into higher credit quality, shorter duration issuances. The increase in the securities portfolio in the year over year period was primarily due to $1.07 billion of securities acquired in our acquisition of West Suburban, as well as $1.03 billion of purchases in the last twelve months, less $601.0 million of sales in that same period, to utilize our excess cash on hand. There was one security sale during the second quarter of 2022 and one during the second quarter of 2021, resulting in a loss of $33,000 and gain of $2,000 respectively.

Total loans were $3.63 billion as of June 30, 2022, an increase of $204.3 million from December 31, 2021. The increase in total loans in the first six months of 2022, compared to December 31, 2021, was due primarily to growth in loan originations within commercial real estate – investor, which increased by $119.3 million, and leases, which increased by $54.6 million from December 31, 2021. Total loans increased $1.72 billion from June 30, 2021 to June 30, 2022, primarily due to the loan portfolio acquired from West Suburban. As required by CECL, the balance (or amortized cost basis) of purchased credit deteriorated loans, or PCD loans (discussed below) is 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 71.0% of the portfolio as of June 30, 2022, compared to 71.6% of the portfolio as of December 31, 2021. 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 decreased by $2.6 million to $42.1 million at June 30, 2022 from $44.7 million at December 31, 2021. 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. Management continues to carefully monitor loans considered to be in a classified status. Nonperforming loans as a percent of total loans were 1.2% as of June 30, 2022, 1.3% as of December 31, 2021, and 1.2% as of June 30, 2021. The distribution of our nonperforming loans is shown in the following table.

​

Net charge-offs of $250,000 were recorded for the second quarter of 2022, compared to net charge-offs of $293,000 for the first quarter of 2022, and net charge-offs of $65,000 for the second quarter of 2021, reflecting continuing management attention to credit quality and remediation efforts. The net charge-offs for the second quarter of 2022 were primarily due to one commercial real estate - investor charge off for 243,000. 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.

​

Total classified loans and classified assets increased $27.7 million as of June 30, 2022, from the levels at December 31, 2021. The increase is due to the addition of four commercial real estate – investor loans totaling $19.7 million and one commercial real estate – owner occupied loan for $15.4 million in the second quarter. The increase from June 30, 2021 is primarily due to the $15.4 million addition of the West Suburban loan portfolio in late 2021. 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 17.79% for the period ended June 30, 2022, compared to 13.79% as of December 31, 2021, and 10.75% as of June 30, 2021. The increase in the classified assets ratio for the period ended June 30, 2022, compared to June 30, 2021, is also due to the acquisition of West Suburban Bank.

​

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.

​

At June 30, 2022, our allowance for credit losses (“ACL”) on loans totaled $45.4 million, and our ACL on unfunded commitments, included in other liabilities, totaled $4.7 million. In the second quarter of 2022, we recorded provision expense on loans of $1.3 million, based on our assessment of nonperforming loan metrics and trends and estimated future credit losses, which was offset by a $780,000 reduction in our reserve on unfunded commitments, 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. These two entries resulted in a $550,000 net impact to the provision for credit losses for the second quarter of 2022.

The ACL on loans totaled $44.3 million as of both March 31, 2022 and December 31, 2021, and $28.6 million as of June 30, 2021. The ACL on loans increased in late 2021 due to the impact of the West Suburban acquisition Day One credit mark of $12.1 million, the Day Two non-PCD loan adjustment to ACL of $12.2 million, less a reversal of $2.3 million related to our legacy loan portfolio and net charge-offs of $4.7 million for the fourth quarter. The ACL for loans was reduced in the second quarter of 2021 due to a $2.3 million release of the provision for credit losses.

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 loans, leases and unfunded commitments. Our ACL on loans to total loans was 1.3% as of June 30, 2022, and December 31, 2021. See Item 7 – Critical Accounting Estimates in the Management Discussion and Analysis in our 2021 Annual Report in Form 10-K for discussion of our ACL methodology on loans.

The coverage ratio of the ACL on loans to nonperforming loans was 107.8% as of June 30, 2022, which was a decrease from the coverage ratio of 116.7% as of March 31, 2021 and a decrease from 123.9% as of June 30, 2021. When measured as a percentage of average loans, our total ACL on loans was 1.31% for the six months ended June 30, 2022 and 1.46% for the like period of June 30, 2021

​

In management’s judgment, an adequate ACL has been established to encompass the current lifetime expected credit losses at June 30, 2022, 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 or other factors, such as the war in Ukraine, 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, 2022, OREO totaled $1.6 million, reflecting a $732,000 decrease from the $2.4 million at December 31, 2021, and a $254,000 decrease from the $1.9 million at June 30, 2021. In the second quarter of 2022, we disposed of three properties totaling $646,191 in net book value, which resulted in a gain on sale of OREO of $81,000 and no transfers to OREO. In the fourth quarter of 2021, we acquired three OREO properties in our acquisition of West Suburban, with a total fair value of $5.6 million, and we sold two of these properties in December, which had a net book value of $5.2 million. In the second quarter of 2022, we recorded $104,000 of OREO valuation reserve adjustments, compared to $14,000 of valuation reserve adjustments recorded in the fourth quarter of 2021, and $61,000 of valuation reserve adjustments recorded in the second quarter of 2021.

​

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 $930,000, or approximately 57.2% of total OREO at June 30, 2022, have been in OREO for five years or more. The appropriate regulatory approval has been obtained for any OREO properties held in excess of five years.

Total deposits were $5.34 billion at June 30, 2022, which reflects a $123.4 million decrease from total deposits of $5.47 billion at December 31, 2021, and an increase of $2.66 billion from total deposits of $2.68 billion at June 30, 2021. The decrease in deposits at June 30, 2022, compared to December 31, 2021, was primarily due to decreases in demand deposits of $15.2 million, money market

accounts of $108.3 million and time deposits of $42.4 million partially offset by increases in savings and NOW accounts of $42.6 million. The increase in deposits at June 30, 2022, compared to June 30, 2021 was primarily due to an increase of $2.69 billion of deposits from the West Suburban acquisition.

​

In addition to deposits, we obtained funding from other sources in all periods presented. Securities sold under repurchase agreements totaled $37.6 million at June 30, 2022, a $12.7 million, or 25.3%, decrease from $50.3 million at December 31, 2021. Our notes payable and other borrowings is comprised of $11.0 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 $11.0 million as of June 30, 2022, decreased $8.1 million from December 31, 2021, and decreased $10.2 million from June 30, 2021.

​

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 $44.5 million, net of deferred issuance costs, as of June 30, 2022. These notes mature in December 2026, and included interest payable semi-annually at 5.75% for five years. Beginning December 31, 2021, the interest became 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, 2022, 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, 2022, total stockholders’ equity was $448.9 million, which was a decrease of $53.1 million from $502.0 million as of December 31, 2021. This decrease is primarily attributable to a decrease in accumulated other comprehensive income of $74.0 million in the first six months of 2022 due to a net decrease in unrealized gains on available-for-sale securities, net of unrealized losses on swaps, due to the increase in market interest rates, as well as a reduction to retained earnings of $4.4 million for payment of dividends to our common stockholders in the first six months of 2022. Partially offsetting this decrease was $24.3 million of net income for the six months ended June 30, 2022. Total stockholders’ equity as of June 30, 2022, increased $133.0 million compared to June 30, 2021, primarily due to the West Suburban acquisition in late 2021 and the resultant additional common stock issued, as well as net income year over year, less the reduction in accumulated other comprehensive income of $79.7 million year over year.

​

As part of its response to the impact of the COVID-19 pandemic, in the first quarter of 2020, U.S. federal regulatory authorities issued an interim final rule that provided banking organizations that adopted CECL during the 2020 calendar year with the option to delay for two years the estimated impact of CECL on regulatory capital relative to regulatory capital determined under the prior incurred loss methodology, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided during the initial two-year delay (i.e., a five-year transition in total). In connection with our adoption of CECL on January 1, 2020, we elected to utilize the five-year CECL transition. As of June 30, 2022, the capital measures of the Company exclude $2.9 million, which is the modified CECL transition adjustment.

​

As of June 30, 2022, 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 8.08% at December 31, 2021, to 7.47% at June 30, 2022. Our GAAP tangible common equity to tangible assets ratio was 5.89% at June 30, 2022, compared to 6.54% as of December 31, 2021. Our non-GAAP tangible common equity to tangible assets ratio, which management also considers a valuable performance measurement for capital analysis, decreased from 6.59% at December 31, 2021, to 5.93% at June 30, 2022, primarily due to a decline in tangible common equity in the second quarter of 2022. The decline in tangible common equity was due to a decrease in accumulated other comprehensive income of $74.0 million primarily related to unrealized losses on available-for-sale securities stemming from the increase in market interest rates. The non-GAAP tangible common equity to tangible assets ratio was also negatively impacted by growth in total tangible assets in the second quarter of 2022.

​

The non-GAAP intangible asset exclusion reflects the 80% core deposit limitation per Basel III guidelines within risk based capital calculations, and is useful for us when reviewing risk based capital ratios and equity performance metrics.

​

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, 2022, our cash on hand liquidity totaled $281.3 million, a decrease of $470.8 million over cash balances held as of December 31, 2021.

​

Net cash inflows from operating activities were $27.1 million during the first six months of 2022, compared with net cash inflows of $24.5 million in the same period of 2021. Proceeds from sales of loans held-for-sale, net of funds used to originate loans held-for-sale, were a source of inflows for the first six months of 2022, and for the like period of 2021. Interest paid, net of interest received, combined with changes in other assets and liabilities were a source of outflows for the six months ended June 30, 2022, but were a source of inflows for the like period of 2021. 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 outflows from investing activities were $349.7 million in the six months ended June 30, 2022, compared to net cash inflows of $47.0 million in the same period in 2021. In the first six months of 2022, securities transactions accounted for net outflows of $149.4 million, and the principal change on loans accounted for net outflows of $200.0 million. In the first six months of 2021, securities transactions accounted for net outflows of $86.3 million, and net principal on loans funded accounted for net inflows of $133.4 million. Proceeds from sales of OREO accounted for $845,000 and $565,000 in investing cash inflows for the six months ended June 30, 2022 and 2021, respectively.

​

Net cash outflows from financing activities in the six months ended June 30, 2022, were $148.2 million, compared with net cash inflows of $191.4 million in the six months ended June 30, 2021. Net deposit outflows in the first six months of 2022 were $122.6 million compared to net deposit inflows of $144.9 million in the first six months of 2021. Other short-term borrowings had no net cash inflows or outflows in the first six months of 2022 or 2021. Changes in securities sold under repurchase agreements accounted for outflows of $12.7 million and inflows of $1.6 million for the six months ended June 30, 2022 and 2021, respectively. Dividends paid on our common stock totaled $4.4 million in the six months ended June 30, 2022, compared to dividends paid of $1.7 million for the like 2021 period, as the per common share dividend was increased to five cents per share in the second quarter of 2021. The repurchase of treasury stock in the first six months of 2022 resulted in outflows of $400,000, compared to cash outflows of $10.4 million in the first six months of 2021.

​

Cash and cash equivalents for the six months ended June 30, 2022, totaled $281.3 million, as compared to $592.8 million as of June 30, 2021. 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 $30.0 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 raised the federal funds target rate by 0.75% in June 2022 and by another 0.75% in July 2022. The current market expectation is a federal funds target rate of 3.50% by the end of the year, however the market sentiment has been evolving week by week. We manage interest rate risk within guidelines established by policy that are intended to limit the amount of rate exposure. In practice, we seek to manage our interest rate risk exposure within our guidelines so that such exposure does not pose a material risk to our future earnings.

We 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, 2022 and December 31, 2021 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 on-balance sheet and off-balance sheet positions, which includes interest rate swap derivatives as discussed in Note 19 of our consolidated financial statements found in in our Annual Report on Form 10-K for the year ended December 31, 2021. 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 June 30, 2022, our net interest income profile remained sensitive to earnings gains (in both dollars and percentage) should interest rates rise. We have a moderately lower sensitivity profile quarter-over-quarter due to mild mix change in repricing characteristics of new acquired loans.

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%, 1.0%, and 2.0% and no change in the slope of the yield curve. Down rate scenarios remained not meaningful below -1.0% as certain rates would still fall below zero in those 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.

​

Effects of Inflation

​

In management’s opinion, changes in interest rates affect our financial condition to a far greater degree than changes in the inflation rate; however, we monitor both. The annual inflation rate in the U.S. accelerated to 9.1% in June 2022, the highest since December 1981. Management believes the inflation rate will remain elevated in the near term, which is expected to be favorable for the Bank. In general, we anticipate that higher inflation will increase borrowers’ needs for credit as a result of GDP growth. In addition, as interest rates are expected to rise to combat inflation, we also expect our net interest margin to be favorably impacted. The downside risks of high inflation puts upwards pressure to our expenses, which could impact profits. Furthermore, higher costs of living weaken the financial condition of our borrowers which could affect our credit profile. A financial institution’s ability to be relatively unaffected by changes in interest rates is a good indicator of its capability to perform in today’s volatile economic environment. We seek to mitigate the impact of interest rate volatility on the Bank by seeking to ensure that rate sensitive assets and rate sensitive liabilities respond to changes in interest rates in a similar time frame and to a similar degree. Overall, we expect the effects of higher inflation to be beneficial to us in the near term.

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, 2022. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that as of June 30, 2022, 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, 2022, 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.
