Basis of Financial Statement Presentation

These unaudited consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements included in Busey's 2022 Annual Report. These interim unaudited consolidated financial statements serve to update our 2022 Annual Report and may not include all information and notes necessary to constitute a complete set of financial statements.

We prepared these unaudited consolidated financial statements in conformity with GAAP. We have eliminated intercompany accounts and transactions. We have also reclassified certain prior year amounts to conform to the current period presentation. These reclassifications did not have a material impact on our consolidated financial condition or results of operations.

In our opinion, the unaudited consolidated financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

Use of Estimates

In preparing the accompanying unaudited consolidated financial statements in conformity with GAAP, Busey’s management is required to make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures provided. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of debt securities available for sale, fair value of assets acquired and liabilities assumed in business combinations, goodwill, income taxes, and the determination of the ACL.

Impact of Recently Adopted Accounting Standards

In March 2022, the FASB issued ASU 2022-02 “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures,” which eliminates the TDR accounting model for creditors that have already adopted CECL. In lieu of the TDR accounting model, loan refinancing and restructuring guidance in ASC Subtopic 310-20-35-9 through 35-11 “Receivables—Nonrefundable Fees and Other Costs—Subsequent Measurement—Loan Refinancing or Restructuring” will apply to all loan modifications, including those made for borrowers experiencing financial difficulty. This standard also enhances disclosure requirements related to certain loan modifications. Additionally, this standard introduces new requirements to disclose gross write-off information in the vintage disclosures of financing receivables by credit quality indicator and class of financing receivable by year of origination. This standard applies prospectively. For the transition method related to the recognition and measurement of TDRs, there is an option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. This standard became effective for Busey beginning January 1, 2023. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations.

In March 2022, the FASB issued ASU 2022-01 “Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method,” which replaces the current last-of-layer hedge accounting method with an expanded portfolio layer method that permits multiple hedged layers of a single closed portfolio. The scope of the portfolio layer method is also expanded to include non-prepayable financial assets. This update also provides additional guidance on the accounting for and disclosure of hedge basis adjustments that are applicable to the portfolio layer method, and specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. Amendments related to hedge basis adjustments which are included in this standard apply on a modified retrospective basis by means of a cumulative-effect adjustment to the opening balance of retained earnings on the initial application date. Amendments related to disclosure which are included in this standard may be applied on a prospective basis from the initial application date, or on a retrospective basis to each prior period presented after the date of adoption of the amendments in ASU 2017-12 “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” This standard became effective for Busey beginning January 1, 2023. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations.

ASU 2021-08 “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” requires measurement and recognition in accordance with ASC Topic 606 “Revenue from Contracts with Customers” for contract assets and contract liabilities acquired in a business combination. This update became effective for Busey beginning January 1, 2023. This standard applies prospectively to all business combinations that occur on or after the date it is adopted. Adoption of this standard did not have an impact on Busey’s financial position or results of operations.

Recently Issued Accounting Standards Not Yet Adopted

In March 2023, the FASB issued ASU 2023-02 “Investments—Equity Method and Joint Ventures (Topic 323),” permitting an election to use the proportional amortization method to account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits, regardless of the tax credit program from which the income tax credits are received, provided that certain conditions are met. The proportional amortization method results in the cost of the investment being amortized in proportion to the income tax credits and other income tax benefits received, with the amortization of the investment and the income tax credits being presented net in the income statement as a component of income tax expense. This standard must be applied on a retrospective or modified retrospective basis, and is applicable for Busey beginning on January 1, 2024. Early adoption is permitted. Busey is currently evaluating the potential effect on the Company’s financial position and results of operations, and upon adoption expects changes to be reflected in the Other Expense and Income Taxes line items in the Consolidated Statements of Income.

In March 2023, the FASB issued ASU 2023-01 “Leases (Topic 842): Common Control Arrangements,” which requires amortization over the useful life of leasehold improvements (not the lease term) when the lease is between entities under common control, and any value of such leasehold improvements remaining at the end of the lease term is to be accounted for as a transfer between entities under common control. This standard may be adopted either prospectively, or retrospectively, and is effective for Busey beginning January 1, 2024. Early adoption is permitted. Busey is currently evaluating the potential effect on the Company’s financial position and results of operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

In June 2022, the FASB issued ASU 2022-03 “Fair Value Measurements (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions,” which clarifies that contractual restrictions on the sale of equity securities are not considered in measuring the fair value of those equity securities, and further that contractual sale restrictions cannot be recognized and measured as a separate unit of account. This standard applies prospectively, and is effective for Busey beginning January 1, 2024. Early adoption is permitted. Busey is currently evaluating the potential effect on the Company’s financial position and results of operations.

Subsequent Events

Busey has evaluated subsequent events for potential recognition and/or disclosure through the date the unaudited consolidated financial statements included in this Quarterly Report were issued. There were no significant subsequent events for the quarter ended June 30, 2023, through the filing date of these unaudited consolidated financial statements.

Unrealized and unrecognized losses were related to changes in market interest rates and market conditions that do not represent credit-related impairments. Busey does not intend to sell securities that are in an unrealized or unrecognized loss position, and it is more likely than not that the Company will recover the amortized cost prior to being required to sell the debt securities. Full collection of the amounts due according to the contractual terms of the debt securities is expected; therefore, no ACL was recorded in relation to debt securities, and the impairment related to noncredit factors is recognized in AOCI, net of applicable taxes. As of June 30, 2023, Busey did not hold general obligation bonds of any single issuer, the aggregate of which exceeded 10% of the Company’s stockholders’ equity.

Note 3: Portfolio Loans

Risk Grading

Busey utilizes a loan grading scale to assign a risk grade to all of its loans. A description of the general characteristics of each grade is as follows:

•Pass – This category includes loans that are all considered acceptable credits, ranging from investment or near investment grade, to loans made to borrowers who exhibit credit fundamentals that meet or exceed industry standards.

•Watch – This category includes loans that warrant a higher-than-average level of monitoring to ensure that weaknesses do not cause the inability of the credit to perform as expected. These loans are not necessarily a problem due to other inherent strengths of the credit, such as guarantor strength, but have above average concern and monitoring.

•Special mention – This category is for “Other Assets Specially Mentioned” loans that have potential weaknesses, which may, if not checked or corrected, weaken the asset or inadequately protect the Company’s credit position at some future date.

•Substandard – This category includes “Substandard” loans, determined in accordance with regulatory guidelines, for which the accrual of interest has not been stopped. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

•Substandard non-accrual – This category includes loans that have all the characteristics of a “Substandard” loan with additional factors that make collection in full highly questionable and improbable. Such loans are placed on non-accrual status and may be dependent on collateral with a value that is difficult to determine.

All loans are graded at their inception. Commercial lending relationships that are $1.0 million or less are usually processed through an expedited underwriting process. Most commercial loans greater than $1.0 million are included in a portfolio review at least annually. Commercial loans greater than $0.35 million that have a grading of special mention or worse are typically reviewed on a quarterly basis. Interim reviews may take place if circumstances of the borrower warrant a more frequent review.

Gross interest income recorded on 90+ days past due loans, and that would have been recorded on non-accrual loans if they had been accruing interest in accordance with their original terms, was $0.3 million and $0.7 million for the three and six months ended June 30, 2023, respectively, and was $0.3 million and $0.5 million for the three and six months ended June 30, 2022, respectively. The amount of interest collected on those loans and recognized on a cash basis that was included in interest income was insignificant for the three and six months ended June 30, 2023. Interest collected on these loans and recognized on a cash basis was insignificant for the three months ended June 30, 2022, and was $0.4 million for the six months ended June 30, 2022.

___________________________________________

1.A loan with payment deferral was modified to defer all principal payments until the end of the loan term, which was shortened.

2.Loans with payment deferrals represent an insignificant portion of commercial loans and total loans, rounding to zero percent.

3.Modifications to extend loan terms also included, in some cases, interest rate increases during the extension period.

4.Modifications include two loans on non-accrual status, one on special mention status, and the remaining loans were classified as substandard.

The following table summarizes the effects of loan modifications made during the periods indicated, for borrowers experiencing financial difficulty:

	Three Months Ended June 30, 2023	Six Months Ended June 30, 2023
	Weighted Average Term Extension	Weighted Average Term Extension

The following table provides the amortized cost basis of financing receivables that had a payment default during the period and were modified in the 12 months before default for borrowers experiencing financial difficulty (dollars in thousands). A default occurs when a loan is 90 days or more past due or transferred to non-accrual status.

TDR Disclosures Prior to the Adoption of ASU 2022-02

At December 31, 2022, performing TDR’s were $3.0 million and non-performing TDR’s were $0.5 million.

One loan was newly designated as a TDR during the three and six months ended June 30, 2022. There were no TDRs entered into during the 12 months ended June 30, 2022, that had subsequent defaults during the three or six months ended June 30, 2022. Gross interest income that would have been recorded in the three and six months ended June 30, 2022, if TDRs had performed in accordance with their original terms compared with their modified terms, was insignificant.

Collateral Dependent Loans

Management's evaluation as to the ultimate collectability of loans includes estimates regarding future cash flows from operations and the value of property, real and personal, pledged as collateral. These estimates are affected by changing economic conditions and the economic prospects of borrowers. Collateral dependent loans are loans in which repayment is expected to be provided solely by the underlying collateral and there are no other available and reliable sources of repayment. Loans are written down to the lower of cost or fair value of underlying collateral, less estimated costs to sell. The Company had $13.6 million and $14.0 million of collateral dependent loans secured by real estate or business assets as of June 30, 2023, and December 31, 2022, respectively.

Foreclosures

As of June 30, 2023, Busey had $1.1 million of residential real estate in the process of foreclosure. Busey follows Federal Housing Finance Agency guidelines on single-family foreclosures and real estate owned evictions on portfolio loans.

Loans Evaluated Individually

Busey evaluates loans with disparate risk characteristics on an individual basis. The following tables provide details of loans evaluated individually, segregated by loan category and class. The unpaid principal balance represents customer outstanding contractual principal balances excluding any partial charge-offs. Recorded investment represents the amortized cost of customer balances net of any partial charge-offs recognized on the loan. Average recorded investment is calculated using the most recent four quarters (dollars in thousands):

Allowance for Credit Losses

Management estimates the ACL balance using relevant available information from internal and external sources relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. The cumulative loss rate used as the basis for the estimate of credit losses is comprised of Busey’s historical loss experience beginning in 2010. Due to the continued economic uncertainty in the markets in which the Company operates, Busey will continue to utilize a forecast period of 12 months with an immediate reversion to historical loss rates beyond this forecast period in its ACL estimate. PPP loans were excluded from the ACL calculation as they are 100% government guaranteed.

Term Loan

On May 28, 2021, Busey entered into a Second Amended and Restated Credit Agreement, pursuant to which Busey has access to (i) a $40.0 million revolving line of credit with a termination date of April 30, 2022, and (ii) a $60.0 million term loan with a maturity date of May 31, 2026. The loans had an annual interest rate of 1.75% plus the one-month LIBOR rate. On April 30, 2022, the agreement was amended, effecting an extension of the termination date for the revolving line of credit to April 30, 2023, and providing for the transition from a LIBOR-indexed interest rate to a SOFR-indexed interest rate. Under the terms of the amendment, the loans now have an annual interest rate of 1.80% plus the one-month forward-looking term rate based on SOFR. On April 30, 2023, the agreement was further amended to extend the term for the revolving line of credit to April 30, 2024.

Senior and Subordinated Notes

On June 1, 2020, Busey issued $125.0 million of fixed-to-floating rate subordinated notes that mature on June 1, 2030. The subordinated notes, which qualify as Tier 2 capital for Busey, bear interest at an annual rate of 5.25% for the first five years after issuance and thereafter bear interest at a floating rate equal to a three-month benchmark rate plus a spread of 5.11%, as calculated on each applicable determination date. Interest on the subordinated notes is payable semi-annually on each June 1 and December 1 during the five-year fixed-term, and thereafter on March 1, June 1, September 1, and December 1 of each year, commencing on September 1, 2025. The subordinated notes have an optional redemption, in whole or in part, on any interest payment date on or after June 1, 2025. The subordinated notes are unsecured obligations of the Company.

On June 2, 2022, Busey issued $100.0 million aggregate principal amount of 5.000% fixed-to-floating rate subordinated notes maturing June 15, 2032, which qualify as Tier 2 capital for regulatory purposes. The price to the public for the subordinated notes was 100% of the principal amount of the subordinated notes. Interest on the subordinated notes accrues at a rate equal to (i) 5.000% per annum from the original issue date to, but excluding, June 15, 2027, payable semiannually in arrears, and (ii) a floating rate per annum equal to a benchmark rate, which is expected to be the Three-Month Term SOFR (as defined in the subordinated notes), plus a spread of 252 basis points from and including, June 15, 2027, payable quarterly in arrears. The subordinated notes have an optional redemption, in whole or in part, on any interest payment date on or after June 15, 2027.

Note 7: Regulatory Capital

First Busey Corporation and Busey Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory—and possibly additional discretionary—actions by regulators that, if undertaken, could have a direct material effect on Busey's consolidated financial statements. Capital amounts and classification also are subject to qualitative judgments by regulators about components, risk weightings, and other factors.

Banking regulations identify five capital categories for insured depository institutions: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. As of June 30, 2023, and December 31, 2022, all capital ratios of First Busey Corporation and Busey Bank exceeded well capitalized levels under the applicable regulatory capital adequacy guidelines. Management believes that no events or changes have occurred subsequent to June 30, 2023, that would change this designation.

Current Expected Credit Loss Model

On August 26, 2020, the FDIC and other federal banking agencies adopted a final rule which provided banking organizations that adopted CECL during 2020 with the option to delay for two years the estimated impact of CECL on regulatory capital and to phase in the aggregate impact of the deferral on regulatory capital over a subsequent three-year period. Under this final rule, because the Company has elected to use the deferral option, the regulatory capital impact of our transition adjustments recorded on January 1, 2020, arising from the adoption of CECL, was deferred for two years. In addition, 25 percent of the ongoing impact of CECL on our ACL, retained earnings, and average total consolidated assets from January 1, 2020, through the end of the two-year deferral period, each as reported for regulatory capital purposes, has been added to the deferred transition amounts (“adjusted transition amounts”) and deferred for the two-year period. On January 1, 2022, at the conclusion of the two-year period, the adjusted transition amounts began to be phased-in for regulatory capital purposes at a rate of 25 percent per year, with the phased-in amounts included in regulatory capital at the beginning of each year.

Capital Conservation Buffer

In July 2013, U.S. federal banking authorities approved the Basel III Rule for strengthening international capital standards. The Basel III Rule introduced a capital conservation buffer, composed entirely of common equity Tier 1 capital, which is added to the minimum risk-weighted asset ratios. The capital conservation buffer is not a minimum capital requirement; however, banking institutions with a ratio of common equity Tier 1 capital to risk-weighted assets below the capital conservation buffer will face constraints on dividends, equity repurchases, and discretionary bonus payments based on the amount of the shortfall. In order to refrain from restrictions on dividends, equity repurchases, and discretionary bonus payments, banking institutions must maintain minimum ratios of (i) common equity Tier 1 capital to risk-weighted assets of at least 7.0%, (ii) Tier 1 capital to risk-weighted assets of at least 8.5%, and (iii) total capital to risk-weighted assets of at least 10.5%.

The 2020 Equity Plan was approved by stockholders at the 2020 Annual Meeting of Stockholders. A description of the 2020 Equity Plan can be found in Busey’s Proxy Statement for the 2020 Annual Meeting of Stockholders filed on April 9, 2020. The Amended 2020 Equity Plan was approved by stockholders at the 2023 Annual Meeting of Stockholders. The terms of the Amended 2020 Equity Plan are substantially identical to those of the stockholder approved 2020 Equity Plan, other than an increase of 1,350,000 in the number of shares authorized for issuance under the plan. More information can be found in Busey’s Proxy Statement for the 2023 Annual Meeting of Stockholders filed on April 14, 2023.

Under the terms of the 2020 Equity Plan, Busey has granted RSU, PSU, and DSU awards. Upon vesting and delivery, shares are expected (though not required) to be issued from treasury. There were 1,536,783 shares available for issuance under the Amended 2020 Equity Plan as of June 30, 2023.

RSU Awards

Busey grants RSUs to members of management periodically throughout the year. Each RSU is equivalent to one share of Busey’s common stock. These units have requisite service periods ranging from one year to five years, subject to accelerated vesting upon eligible retirement from the Company. Recipients earn quarterly dividend equivalents on their respective units which entitle the recipients to additional units. Therefore, dividends earned each quarter compound based upon the updated unit balances.

On March 22, 2023, under the terms of the 2020 Equity Plan, Busey granted 224,316 RSUs to members of management. The grant date fair value of the award totaled $4.6 million and will be recognized as compensation expense over the requisite service period ranging from one year to five years. The terms of these awards included an accelerated vesting provision upon eligible retirement from the Company, after a one-year minimum requisite service period. Subsequent to the requisite service period, the awards will become 100% vested.

A summary of changes in Busey’s RSU awards for the six months ended June 30, 2023, is as follows:

	RSU Awards
	Shares	Weighted- Average Grant Date Fair Value
Nonvested at December 31, 2022	1,096,931	$	23.61

Nonvested at June 30, 2023	1,335,443	23.00

PSU Awards

Busey grants PSUs, which are restricted stock units that are subject to certain performance criteria, to members of management periodically throughout the year. Each PSU is equivalent to one share of Busey’s common stock. The number of units that ultimately vest will be determined based on the achievement of the market or other performance goals, subject to accelerated service-based vesting conditions upon eligible retirement from the Company.

On March 22, 2023, under the terms of the 2020 Equity Plan, Busey granted a target of 104,643 PSUs with a maximum award of 167,429 units. The actual number of units issued at the vesting date could range from 0% to 160% of the initial grant, depending on attaining a market-based total stockholder return performance goal. The grant date fair value of the award was $2.0 million and will be recognized in compensation expense over the performance period ending December 31, 2025.

Derivative Instruments Designated as Hedges

Busey entered into derivative instruments designated as cash flow hedges. For a derivative instrument that is designated and qualifies as a cash flow hedge, the change in fair value of the derivative instrument is reported as a component of OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Changes in fair value of components excluded from the assessment of effectiveness are recognized in current earnings.

Interest Rate Swaps Designated as Cash Flow Hedges

Interest rate swaps with notional amounts totaling $350.0 million as of both June 30, 2023, and December 31, 2022, were designated as cash flow hedges. Busey entered into one $50.0 million interest rate swap to hedge the risks of variability in cash flows for future interest payments attributable to changes in the contractually specified 3-month LIBOR benchmark interest rate on the Busey’s junior subordinated debt owed to unconsolidated trusts (Debt Swap). In addition, Busey entered into one $300.0 million receive fixed pay floating interest rate swap to reduce Busey’s asset sensitivity (Loan Swap). Duration was added to our loan portfolio by fixing a portion of floating prime based loans. Interest rates had risen above their historical lows allowing Busey to lock in a portion of its loan portfolio to reduce asset sensitivity while creating a more stable margin in a volatile rate market. These hedges were determined to be highly effective during the period, and Busey expects its hedges to remain highly effective during the remaining terms of the swaps. Changes in fair value were recorded net of tax in OCI.

Derivative Instruments Not Designated as Hedges

Interest Rate Swaps Not Designated as Hedges

Busey may offer derivative contracts to its customers in connection with their risk management needs. Busey manages the risk associated with these contracts by entering into equal and offsetting derivative agreements with a third-party dealer. These contracts support variable rate, commercial loan relationships totaling $623.2 million as of June 30, 2023, and $576.9 million as of December 31, 2022. These derivatives generally work together as an economic interest rate hedge, but Busey did not designate them for hedge accounting treatment. Consequently, changes in fair value of the corresponding derivative financial asset or liability are recorded as either a charge or credit to current earnings during the period in which the changes occurred.

Note 11: Fair Value Measurements

The fair value of an asset or liability is the price that would be received by selling that asset or paid in transferring that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. ASC Topic 820 “Fair Value Measurement” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

•Level 1 Inputs—Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

•Level 2 Inputs—Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

•Level 3 Inputs—Unobservable inputs for determining the fair values of assets or liabilities that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to those Company assets and liabilities that are carried at fair value.

In general, fair value is based upon quoted market prices, when available. If such quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable data. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect, among other things, counterparty credit quality and the company's creditworthiness as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. While management believes Busey's valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

Financial Assets and Financial Liabilities Measured at Fair Value on a Recurring Basis

Debt Securities Available for Sale

Debt securities classified as available for sale are reported at fair value utilizing Level 2 inputs. Busey obtains fair value measurements from an independent pricing service. The independent pricing service utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid, and other market information. Because many fixed income securities do not trade on a daily basis, the independent pricing service applies available information, focusing on observable market data such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations.

The independent pricing service uses model processes, such as the Option Adjusted Spread model, to assess interest rate impact and develop prepayment scenarios. Models and processes take into account market conventions. For each asset class, a team of evaluators gathers information from market sources and integrates relevant credit information, perceived market movements, and sector news into the evaluated pricing applications and models.

Market inputs that the independent pricing service normally seeks for evaluations of securities, listed in approximate order of priority, include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications. The independent pricing service also monitors market indicators, industry, and economic events. For certain security types, additional inputs may be used or some of the market inputs may not be applicable. Evaluators may prioritize inputs differently on any given day for any security based on market conditions, and not all inputs listed are available for use in the evaluation process for each security evaluation on a given day. Because the data utilized was observable, the securities have been classified as Level 2.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

Equity Securities

Equity securities are reported at fair value utilizing Level 1 or Level 2 inputs. Fair value measurements of mutual funds, when held, are determined using unadjusted quoted prices in active markets for identical assets at the measurement date and are classified as Level 1. Fair value measurements of stock utilize quoted prices for identical or similar assets in markets that are not active and are classified as Level 2.

Derivative Assets and Derivative Liabilities

The majority of our derivative assets and derivative liabilities are reported at fair value utilizing Level 2 or Level 3 inputs. Fair values of derivative assets and liabilities are determined based on prices that are obtained from a third-party which uses observable market inputs and, with the exception of our risk participation agreements, are classified as Level 2. Due to the significance of unobservable inputs, derivative assets related to our risk participation agreements are classified as Level 3.

The following tables summarize financial assets and financial liabilities measured at fair value on a recurring basis as of June 30, 2023, and December 31, 2022, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).

Loans Evaluated Individually

Busey does not record portfolio loans at fair value on a recurring basis. However, periodically, a loan is evaluated individually and is reported at the fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. If the collateral value is not sufficient, a specific reserve is recorded. Collateral values are estimated using a combination of observable inputs, including recent appraisals, and unobservable inputs based on customized discounting criteria. Due to the significance of unobservable inputs, fair values of individually evaluated collateral dependent loans have been classified as Level 3.

OREO and Other Repossessed Assets

Non-financial assets measured at fair value, upon initial recognition or subsequent impairment, include OREO and other repossessed assets. OREO properties and other repossessed assets are measured using a combination of observable inputs, including recent appraisals, and unobservable inputs. Due to the significance of unobservable inputs, the fair values of all OREO and other repossessed assets have been classified as Level 3.

Bank Property Held for Sale

Bank property held for sale represents certain banking center office buildings which Busey has closed and consolidated with other existing banking centers. Bank property held for sale is measured at the lower of amortized cost or fair value less estimated costs to sell. Fair values were based upon discounted appraisals or real estate listing prices. Due to the significance of unobservable inputs, fair values of all bank property held for sale have been classified as Level 3.

The following tables summarize assets and liabilities measured at fair value on a non-recurring basis for the periods presented, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

Note 12: Earnings Per Common Share

Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding, which include DSUs that are vested but not delivered. Diluted earnings per common share is computed using the treasury stock method and reflects the potential dilution that could occur if Busey’s outstanding stock options and warrants were exercised, stock units were vested, and ESPP shares were issued.

Earnings per common share have been computed as follows (dollars in thousands, except per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,

OVERVIEW

First Busey Corporation is a $12.2 billion financial holding company headquartered in Champaign, Illinois. Our common stock is traded on The Nasdaq Global Select Market under the symbol “BUSE.”

Our three operating segments provide a full range of banking, payment technology solutions, and wealth management services through our subsidiaries, Busey Bank and FirsTech, in Illinois; the St. Louis, Missouri metropolitan area; southwest Florida; and Indianapolis, Indiana.

The following discussion and analysis are intended to assist readers in understanding Busey’s financial condition and results of operations during the three and six months ended June 30, 2023, and should be read in conjunction with our Consolidated Financial Statements (unaudited) and the related Notes to the Consolidated Financial Statements (unaudited) included in this Quarterly Report, as well as our 2022 Annual Report.

Busey’s Conservative Banking Strategy

Busey’s financial strength is built on a sound business strategy of conservative banking, and that focus will not change now or in the future.

The quality of our core deposit franchise is a critical value driver of our institution. Despite recent turmoil experienced in certain sectors of the banking industry, we have seen relative stability in our deposit franchise. We have sufficient on- and off-balance sheet liquidity to manage deposit fluctuations and the liquidity needs of our customers. Our credit performance reflects our highly diversified, conservatively underwritten loan portfolio, which has been originated predominantly to established customers with tenured relationships with our Company. Asset quality remains strong by both historical and current industry trends.

Banking Center Markets

Busey Bank serves the Illinois banking market with 46 banking centers. Our Illinois markets feature several Fortune 1000 companies. Those organizations, coupled with large healthcare and higher education sectors, anchor the communities in which they are located and have provided a comparatively stable foundation for housing, employment, and small business. Ten of our banking centers in Illinois are located within the Chicago Metropolitan Statistical Area, and 12 of our banking centers in Illinois are located within the St. Louis Metropolitan Statistical Area.

Busey Bank has eight banking centers in Missouri. St. Louis, Missouri has a diverse economy with major employment sectors including health care, financial services, professional and business services, and retail. We have a total of 20 banking centers within the boundaries of the St. Louis Metropolitan Statistical Area, including branches in both Illinois and Missouri.

Busey Bank has three banking centers in southwest Florida, an area which has experienced strong population growth, job growth, and an expanded housing market, as well as the benefits of a tourism and winter resort economy.

Busey Bank has one banking center in the Indianapolis, Indiana area, which is the most populous city of Indiana with a diverse economy, due in part to it serving as the headquarters of many large corporations.

Net Interest Income

Net interest income is the difference between interest income and fees earned on earning assets and interest expense incurred on interest-bearing liabilities. Interest rate levels and volume fluctuations within earning assets and interest-bearing liabilities impact net interest income. Net interest margin is tax-equivalent net interest income as a percent of average earning assets.

Certain assets with tax favorable treatment are evaluated on a tax-equivalent basis, assuming a federal income tax rate of 21.0%. Tax favorable assets generally have lower contractual pre-tax yields than fully taxable assets. A tax-equivalent analysis is performed by adding the tax savings to the earnings on tax favorable assets. After factoring in the tax favorable effects of these assets, the yields may be more appropriately evaluated against alternative earning assets. In addition to yield, various other risks are factored into the evaluation process.

2.Net interest income expressed as a percentage of average earning assets, stated on a tax-equivalent basis.

The FOMC raised rates by 25 basis points during the second quarter of 2023, and by a total of 500 basis points since the onset of the current FOMC tightening cycle that began in the first quarter of 2022. Rising rates initially have a positive impact on net interest margin, as assets, in particular commercial loans, reprice more quickly and to a greater extent than liabilities. As deposit and funding costs increase in response to the tightening rate cycle, and we experience deposit migration into higher cost offerings along with an increase in wholesale borrowings, some of the net interest margin expansion is reversed.

Busey remains substantially core deposit1 funded, with robust liquidity and significant market share in the communities we serve. As of June 30, 2023, our loan to deposit ratio was 77.6% and core deposits represented 97.0% of total deposits.

Net interest spread, which represents the difference between the average rate earned on earning assets and the average rate paid on interest-bearing liabilities, was 2.26% and 2.48% for the three and six months ended June 30, 2023, respectively, compared to 2.56% and 2.44% for the three and six months ended June 30, 2022, each on a tax-equivalent basis.

The net interest margin discussion above is based upon the results and average balances for the three and six months ended June 30, 2023, and 2022. Annualized net interest margins for the quarterly periods indicated were as follows:

	2023		2022
First Quarter	3.13	%	2.45	%
Second Quarter	2.86	%	2.68	%
Third Quarter			3.00	%
Fourth Quarter			3.24	%

Management attempts to mitigate the effects of an unpredictable interest-rate environment through effective portfolio management, prudent loan underwriting and pricing discipline, and operational efficiencies. For a description of accounting policies underlying the recognition of interest income and expense, refer to the Notes to Consolidated Financial Statements in Busey’s 2022 Annual Report.

Total noninterest income was $28.0 million for the three months ended June 30, 2023, a decrease of 9.7% from the comparable period in 2022, and was $59.9 million for the six months ended June 30, 2023, a decrease of 10.4% from the comparable period in 2022. Combined, revenues from wealth management fees and payment technology solutions represented 70.7% and 66.7% of Busey’s noninterest income for the three and six months ended June 30, 2023, respectively, providing a complement to spread-based revenue from traditional banking activities. On a combined basis, revenue from these two critical operating areas was $19.8 million for the three months ended June 30, 2023, a 4.0% increase from the comparable period in 2022, and was $39.9 million for the six months ended June 30, 2023, an 0.1% increase from the comparable period in 2022.

Wealth management fees were $14.6 million for the three months ended June 30, 2023, a 3.0% increase from the comparable period in 2022, and were $29.4 million for the six months ended June 30, 2023, a 1.9% decrease from the comparable period for 2022. Busey’s Wealth Management division ended the second quarter of 2023 with $11.5 billion in assets under care, which is comparable to June 30, 2022. Our portfolio management team continues to produce solid results in the face of volatile markets.

Payment technology solutions revenue relates to our payment processing company, FirsTech. Payment technology solutions revenue was $5.2 million for the three months ended June 30, 2023, a 7.0% increase from the comparable period in 2022, and was $10.5 million for the six months ended June 30, 2023, a 5.8% increase from the comparable period in 2022. We have made strategic investments in FirsTech to enhance future growth, including upgrades to the product and engineering teams to build an Application Programming Interface (“API”) cloud-based platform to provide for fully integrated payment capabilities as well as the continued development of our Banking as a Service (“BaaS”) platform.

Fees for customer services were $7.2 million for the three months ended June 30, 2023, a 24.5% decrease from the comparable period in 2022, and were $14.1 million for the six months ended June 30, 2023, a 24.0% decrease from the comparable period in 2022. Beginning on July 1, 2022, we became subject to the Durbin Amendment of the Dodd-Frank Act. The Durbin Amendment required the Federal Reserve to establish a maximum permissible interchange fee for many types of debit transactions, which resulted in a reduction in fee income totaling $2.4 million and $4.7 million during the three and six months ended June 30, 2023, respectively. Excluding the impact of the Durbin Amendment, fees for customer services would have shown an increase of 0.8% and 1.3% from the comparable three and six month periods in 2022, respectively.

Mortgage revenue was $0.3 million for the three months ended June 30, 2023, a 4.2% decrease from the comparable period in 2022, and was $0.6 million for the six months ended June 30, 2023, a 55.5% decrease from the comparable period in 2022. Decreases primarily resulted from declines in mortgage origination and sold-loan mortgage volume. General economic conditions and interest rate volatility may impact fees in future quarters.

Income on bank owned life insurance was $1.0 million for the three months ended June 30, 2023, a 17.7% increase from the comparable period in 2022, and was $2.7 million for the six months ended June 30, 2023, a 52.5% increase from the comparable period in 2022. Year to date increases resulted primarily from earnings on death proceeds of $0.8 million.

Net securities losses were $2.1 million for the three months ended June 30, 2023, a 20.1% increase from the comparable period in 2022. Losses were comprised of $0.2 million of realized net losses and $1.9 million of unrealized net losses recognized on equity securities. For the six months ended June 30, 2023, net securities losses were $2.7 million, a 14.9% increase from the comparable period in 2022, and were comprised of $0.2 million of realized net losses and $2.5 million of unrealized net losses recognized on equity securities.

Other income was $1.7 million for the three months ended June 30, 2023, a $1.2 million decrease from the comparable period in 2022, and was $5.3 million for the six months ended June 30, 2023, a $2.4 million decrease from the comparable period in 2022. Other income fluctuations were primarily attributable to lower income recognized on venture capital investments during the three and six months ended June 30, 2023.

Management’s Discussion and Analysis—Non-GAAP Financial Information” included in this Quarterly Report.

Total noninterest expense was $69.2 million for the three months ended June 30, 2023, a 0.2% increase from the comparable period in 2022, and was $139.6 million for the six months ended June 30, 2023, a 0.1% increase from the comparable period in 2022. We remain focused on expense discipline, and have been purposeful in our efforts to rationalize our expense base given our economic outlook and our view on the future of banking. During a time of decades-high inflation, we have effectively managed our noninterest expense base.

Salaries, wages, and employee benefits were $39.9 million for the three months ended June 30, 2023, a 4.6% increase from the comparable period in 2022, and were $80.2 million for the six months ended June 30, 2023, a 3.5% increase from the comparable period in 2022. Full-time equivalents were 1,477 as of June 30, 2023, compared to 1,493 at June 30, 2022. Labor market trends over the past year reflected a tight labor supply, while job gains resulted in increased demands for a skilled workforce, maintaining upward pressure on salaries, wages, and employee benefits.

Data processing expense was $5.9 million for the three months ended June 30, 2023, a 9.8% increase from the comparable period in 2022, and was $11.5 million for the six months ended June 30, 2023, a 11.5% increase from the comparable period in 2022. Increases were primarily attributable to expenses for FirsTech transaction volume and continued Company-wide investments in technology enhancements, as well as inflation-driven price increases.

Combined, net occupancy expense of premises and furniture and equipment expense totaled $6.2 million for the three months ended June 30, 2023, a 8.0% decrease from the comparable period in 2022, and $12.7 million for the six months ended June 30, 2023, a 8.2% decrease from the comparable period in 2022. Year-over-year decreases were primarily attributable to lower maintenance costs and declines in depreciation expense.

67

Professional fees were $1.0 million for the three months ended June 30, 2023, a 39.5% decrease from the comparable period in 2022. This decrease is primarily attributable to a recapture of legal expenses related to the payoff of a large classified asset in the quarter. Professional fees were $3.0 million for the six months ended June 30, 2023, a 2.7% decrease from the comparable period in 2022.

Amortization of intangible assets was $2.7 million for the three months ended June 30, 2023, an 9.6% decrease from the comparable period in 2022, and $5.4 million for the six months ended June 30, 2023, a 9.5% decrease from the comparable period for 2022, due to the use of an accelerated amortization methodology.

Interchange expense was $1.9 million for the three months ended June 30, 2023, a 25.8% increase from the comparable period in 2022, and was $3.7 million for the six months ended June 30, 2023, a 22.8% increase from the comparable period in 2022. Fluctuations in interchange expense were primarily the result of increased payment and volume activity at FirsTech.

FDIC insurance expense was $1.5 million for the three months ended June 30, 2023, a 30.6% increase from the comparable period in 2022, and $3.0 million for the six months ended June 30, 2023, a 35.1% increase from the comparable period in 2022. Increases were the result of an FDIC final rule to increase the initial base deposit insurance assessment rate applicable to all depository institutions by two basis points beginning in 2023.

Other expense was $10.2 million for the three months ended June 30, 2023, a 12.4% decrease from the comparable period in 2022, and was $20.0 million for the six months ended June 30, 2023, a 14.8% decrease from the comparable period in 2022. Decreases were across multiple expense categories as a result of expense discipline in marketing and business development activities and lower check card fees, partially offset by increases in New Markets Tax Credits amortization. Year to date decreases were also influenced by fluctuations in OREO and the provision for unfunded commitments.

The efficiency ratio2, which is a measure commonly used by management and the banking industry, measures the amount of expense incurred to generate a dollar of revenue. Our efficiency ratios were 60.9% and 58.8% for the three and six months ended June 30, 2023, respectively, compared to 60.6% and 61.8% for the three and six months ended June 30, 2022, respectively.

Our adjusted efficiency ratios2 were 60.9% and 58.8% for the three and six months ended June 30, 2023, respectively, compared to 60.3% and 61.2% for three and six months ended June 30, 2022, respectively.

Taxes

Effective income tax rates of 20.3% and 20.5% for the three and six months ended June 30, 2023, respectively, were lower than the combined federal and state statutory rate of approximately 28.0% due to tax exempt interest income, such as municipal bond interest and bank owned life insurance income, and investments in various tax credits. We continue to monitor evolving federal and state tax legislation and its potential impact on operations on an ongoing basis. As of June 30, 2023, we were not under examination by any tax authority; however, we have received an inquiry from the State of Illinois regarding our prior franchise tax filings. In the event the Company is required to amend our prior franchise tax filings, we could incur additional expenses.

2 The efficiency ratio and adjusted efficiency ratio are non-GAAP financial measures. For a reconciliation of non-GAAP measures to the most directly comparable GAAP financial measures, see “Item 2. Management’s Discussion and Analysis—Non-GAAP Financial Information” included in this Quarterly Report.

Portfolio Loans

We believe that making sound and profitable loans is a necessary and desirable means of employing funds available for investment. Busey maintains lending policies and procedures designed to focus lending efforts on the types, locations, and duration of loans most appropriate for its business model and markets. While not specifically limited, we attempt to focus our lending on short to intermediate-term (0-10 years) loans in geographic areas within 125 miles of our lending offices. Loans originated outside of these areas are generally to existing customers of Busey Bank. We attempt to utilize government-assisted lending programs, such as the SBA and U.S. Department of Agriculture lending programs, when prudent. Generally, loans are collateralized by assets, primarily real estate, and guaranteed by individuals. Loans are expected to be repaid primarily from cash flows of the borrowers or from proceeds from the sale of selected assets of the borrowers.

Management reviews and approves Busey Bank’s lending policies and procedures on a regular basis. Management routinely (at least quarterly) reviews the ACL in conjunction with reports related to loan production, loan quality, concentrations of credit, loan delinquencies, non-performing loans, and potential problem loans. Our underwriting standards are designed to encourage relationship banking rather than transactional banking. Relationship banking implies a primary banking relationship with the borrower that includes, at a minimum, an active deposit banking relationship in addition to the lending relationship. Significant underwriting factors, in addition to location, duration, a sound and profitable cash flow basis, and the borrower’s character, include the quality of the borrower’s financial history, the liquidity of the underlying collateral, and the reliability of the valuation of the underlying collateral.

Busey Bank maintains a well-diversified loan portfolio and, as a matter of policy and practice, limits concentration exposure in any particular loan segment.

69

At no time is a borrower’s total borrowing relationship permitted to exceed Busey Bank’s regulatory lending limit. We generally limit such relationships to amounts substantially less than the regulatory limit. Loans to related parties, including executive officers and directors of First Busey Corporation and its subsidiaries, are reviewed for compliance with regulatory guidelines.

Busey maintains an independent loan review department that reviews loans for compliance with our loan policy on a periodic basis. In addition, the loan review department reviews risk assessments made by our credit department, lenders, and loan committees. Results of these reviews are presented to management and the audit committee at least quarterly.

Busey Bank’s lending activities can be summarized into two primary categories: commercial and retail. Lending is further classified into five primary areas: commercial loans, commercial real estate loans, real estate construction loans, retail real estate loans, and retail other loans. A description of each of the five primary areas can be found in Busey’s 2022 Annual Report. A significant majority of our portfolio lending activity occurs in the Illinois and Missouri markets, with the remainder in the Florida and Indiana markets.

Busey generated $79.6 million, or 1.0%, in net loan growth during the six months ended June 30, 2023. Like prior periods, most of the loan growth occurred within the Company’s existing client base. Changes in portfolio loan balances were as follows (dollars in thousands):

As has been our practice, we remain steadfast in our conservative approach to underwriting and disciplined approach to pricing, particularly given our outlook for the economy in the coming quarters. This posture will impact loan growth in subsequent quarters. Given this outlook, loan growth is likely to slow compared to Busey’s results of the last twelve months and our previous expectations.

Allowance and Provision for Credit Losses

The ACL is a significant estimate in our unaudited consolidated financial statements, affecting both earnings and capital. The methodology adopted influences, and is influenced by, Busey Bank’s overall credit risk management processes. The ACL is recorded in accordance with GAAP to provide an adequate reserve for expected credit losses that is reflective of management’s best estimate of what is expected to be collected. Estimates of credit losses are based on a careful consideration of all significant factors affecting collectability as of the evaluation date. The ACL is established through the provision for credit loss expense charged to income. Provision expenses were recorded as follows for each of the periods indicated (dollars in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Provision for credit losses	$	627	$	1,653	$	1,580	$	1,400

As of June 30, 2023, management believed the level of the ACL to be appropriate based upon the information available. However, additional losses may be identified in our loan portfolio as new information is obtained. The ongoing impacts of CECL will be dependent upon changes in economic conditions and forecasts, originated and acquired loan portfolio composition, prepayment speeds, credit performance trends, portfolio duration, and other factors.

Non-Performing Loans and Non-Performing Assets

Loans are considered past due if the required principal or interest payments have not been received as of the date such payments were due. Loans are placed on non-accrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory guidelines. Loans may be placed on non-accrual status regardless of whether or not such loans are considered past due. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Typically, loans are secured by collateral. When a loan is classified as non-accrual and determined to be collateral dependent, it is appropriately reserved or charged down through the ACL to the fair value of our interest in the underlying collateral less estimated costs to sell. Our loan portfolio is collateralized primarily by real estate.

Asset quality remains strong by both historical and current industry trends, and our operating mandate and focus have been on emphasizing credit quality over asset growth. Non-performing loan balances increased by 0.2% to $15.8 million as of June 30, 2023, compared to $15.7 million as of December 31, 2022. We saw a decline in classified assets from $107.1 million as of December 31, 2022 to $81.9 million as of June 30, 2023. Continued disciplined credit management resulted in non-performing loans as a percentage of portfolio loans of 0.20% as of both June 30, 2023, and December 31, 2022.

Asset quality metrics remain dependent upon market-specific economic conditions, and specific measures may fluctuate from period to period. If economic conditions were to deteriorate, we would expect the credit quality of our loan portfolio to decline and loan defaults to increase.

73

Potential Problem Loans

Potential problem loans are loans classified as substandard which are not individually evaluated, non-accrual, or 90+ days past due, but where current information indicates that the borrower may not be able to comply with loan repayment terms. Management assesses the potential for loss on such loans and considers the effect of any potential loss in determining its provision for expected credit losses. Potential problem loans decreased to $66.0 million as of June 30, 2023, compared to $89.2 million as of December 31, 2022. Management continues to monitor these loans and anticipates that restructurings, guarantees, additional collateral, or other planned actions will result in full repayment of the debts. As of June 30, 2023, management identified no other loans that represent or result from trends or uncertainties which would be expected to materially impact future operating results, liquidity, or capital resources.

COVID-19 Modifications

To alleviate some of the financial hardships faced as a result of COVID-19, Busey offered a Financial Relief Program to qualifying customers. The program included options for short-term loan payment deferrals and certain fee waivers. We had no commercial loans remaining in the program, and one payment deferred retail loan representing $0.1 million in loans, as of June 30, 2023. In comparison, we had eight payment deferred commercial loans totaling $20.6 million that were on interest-only payment terms, and one payment deferred retail loans totaling $0.1 million as of December 31, 2022. As the remaining deferral expires, we will continue to monitor for indications of a potential problem loan.

Deposits

Total deposits of $10.1 billion as of June 30, 2023, remained steady with the prior year end balance. We focus on deepening our relationships with customers to strengthen our core deposit3 franchise. Core deposits include non-brokered transaction accounts, money market deposit accounts, and time deposits of $250,000 or less. Core deposits represented 97.0% of total deposits as of June 30, 2023, compared to 98.8% as of December 31, 2022.

LIQUIDITY

Liquidity management is the process by which we ensure that adequate liquid funds are available to meet the present and future cash flow obligations arising in the daily operations of our business. These financial obligations consist of needs for funds to meet commitments to borrowers for extensions of credit, fund capital expenditures, honor withdrawals by customers, pay dividends to stockholders, and pay operating expenses. Our most liquid assets are cash and due from banks, interest-bearing bank deposits, and federal funds sold. Balances of these assets are dependent on our operating, investing, lending, and financing activities during any given period. Average liquid assets are summarized in the table below (dollars in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,
	2023			2022			2023			2022
Average liquid assets
Cash and due from banks	$	118,860		$	121,568		$	117,013		$	124,085
Interest-bearing bank deposits	116,998			230,129			112,550			394,562
Total average liquid assets	$	235,858		$	351,697		$	229,563		$	518,647
Average liquid assets as a percent of average total assets	1.9		%	2.8		%	1.9		%	4.1		%

3 Core deposits is a non-GAAP financial measure. For a reconciliation of non-GAAP measures to the most directly comparable GAAP financial measures, see “Item 2. Management’s Discussion and Analysis—Non-GAAP Financial Information” included in this Quarterly Report.

Cash and unencumbered securities on our Consolidated Balance Sheets are summarized as follows (dollars in thousands):

	As of
	June 30, 2023		December 31, 2022
Cash and unencumbered securities
Total cash and cash equivalents	$	232,703	$	227,164
Debt securities available for sale	2,283,848		2,461,393
Debt securities available for sale pledged as collateral	(636,687)		(746,675)
Cash and unencumbered securities	$	1,879,864	$	1,941,882

Busey’s primary sources of funds consist of deposits, investment maturities and sales, loan principal repayments, and capital funds. Additional liquidity is provided by the ability to borrow from the FHLB, the Federal Reserve, and our revolving credit facility, as summarized in the table below (dollars in thousands):

	As of
	June 30, 2023		December 31, 2022
Additional borrowing capacity available from:
FHLB	$	1,596,430	$	1,765,388
Federal Reserve Bank	650,402		659,680
Federal funds purchased	482,500		482,500
Revolving credit facility	40,000		40,000
Additional borrowing capacity	$	2,769,332	$	2,947,568

Further, the company could utilize brokered deposits as additional sources of liquidity, as needed.

As of June 30, 2023, management believed that adequate liquidity existed to meet all projected cash flow obligations. We seek to achieve a satisfactory degree of liquidity by actively managing both assets and liabilities. Asset management guides the proportion of liquid assets to total assets, while liability management monitors future funding requirements and prices liabilities accordingly.

OFF-BALANCE-SHEET ARRANGEMENTS

Busey Bank routinely enters into commitments to extend credit and standby letters of credit in the normal course of business to meet the financing needs of its customers. The balance of commitments to extend credit represents future cash requirements and some of these commitments may expire without being drawn upon.

The following table summarizes our outstanding commitments and reserves for unfunded commitments (dollars in thousands):

	As of
	June 30, 2023		December 31, 2022
Outstanding loan commitments and standby letters of credit	$	2,143,390	$	2,024,777
Reserve for unfunded commitments	6,232		6,601

The following table summarizes our provision for unfunded commitments expenses (releases) for the periods presented (dollars in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Provision for unfunded commitments expense (release)	$	265	$	(267)	$	(370)	$	845

75

We anticipate we will have sufficient funds available to meet current loan commitments, including loan applications received and in process prior to the issuance of firm commitments.

CAPITAL RESOURCES

Our capital ratios are in excess of those required to be considered “well-capitalized” pursuant to applicable regulatory guidelines. The Federal Reserve Board uses capital adequacy guidelines in its examination and regulation of bank holding companies and their subsidiary banks. Risk-based capital ratios are established by allocating assets and certain off-balance-sheet commitments into risk-weighted categories. These balances are then multiplied by the factor appropriate for that risk-weighted category. In order to refrain from restrictions on dividends, equity repurchases, and discretionary bonus payments, banking institutions must maintain capital in excess of regulatory minimum capital requirements. The table below presents minimum capital ratios that include the capital conservation buffer in comparison to the capital ratios for First Busey and Busey Bank as of June 30, 2023:

	Minimum Capital Requirements with Capital Buffer		As of June 30, 2023
			First Busey		Busey Bank
Common Equity Tier 1 Capital to Risk Weighted Assets	7.00	%	12.35	%	14.76	%
Tier 1 Capital to Risk Weighted Assets	8.50	%	13.17	%	14.76	%
Total Capital to Risk Weighted Assets	10.50	%	16.56	%	15.68	%
Leverage Ratio of Tier 1 Capital to Average Assets	6.50	%	9.93	%	11.12	%

NON-GAAP FINANCIAL INFORMATION

This Quarterly Report contains certain financial information determined by methods other than in accordance with GAAP. Management uses these non-GAAP financial measures and non-GAAP ratios, together with the related GAAP financial measures, in analysis of Busey’s performance and in making business decisions, as well as for comparison to Busey’s peers. We believe the adjusted measures are useful for investors and management to understand the effects of certain non-recurring noninterest items and provide additional perspective on our performance over time.

Non-GAAP disclosures have inherent limitations and are not audited. They should not be considered in isolation or as a substitute for the results reported in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Tax effected numbers included in these non-GAAP disclosures are based on estimated statutory rates and effective rates as appropriate.

A listing of Busey's non-GAAP financial measures and ratios are shown in the table below, together with the related GAAP financial measures.

FORWARD-LOOKING STATEMENTS

Statements made in this document, other than those concerning historical financial information, may be considered forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to Busey’s financial condition, results of operations, plans, objectives, future performance, and business. Forward-looking statements, which may be based upon beliefs, expectations, and assumptions of Busey’s management, and on information currently available to management, are generally identifiable by the use of words such as “believe,” “expect,” “anticipate,” “plan,” “intend,” “estimate,” “may,” “will,” “would,” “could,” “should,” or other similar expressions. Additionally, all statements in this document, including forward-looking statements, speak only as of the date they are made, and we undertake no obligation to update any statement in light of new information or future events. A number of factors, many of which are beyond our ability to control or predict, could cause actual results to differ materially from those in our forward-looking statements. These factors include, among others, the following: (i) the strength of the local, state, national, and international economy (including effects of inflationary pressures and supply chain constraints); (ii) the economic impact of any future terrorist threats or attacks, widespread disease or pandemics (including the Coronavirus Disease 2019 pandemic), or other adverse external events that could cause economic deterioration or instability in credit markets (including Russia’s invasion of Ukraine); (iii) changes in state and federal laws, regulations, and governmental policies concerning Busey’s general business (including changes in response to the recent failures of other banks); (iv) changes in accounting policies and practices (v) changes in interest rates and prepayment rates of Busey’s assets (including the impact of the LIBOR phase-out); (vi) increased competition in the financial services sector (including from non-bank competitors such as credit unions and fintech companies) and the inability to attract new customers; (vii) changes in technology and the ability to develop and maintain secure and reliable electronic systems; (viii) the loss of key executives or associates; (ix) changes in consumer spending; (x) unexpected results of current and/or future acquisitions, which may include failure to realize the anticipated benefits of any acquisition and the possibility that transaction costs may be greater than anticipated; (xi) unexpected outcomes of existing or new litigation involving Busey; (xii) fluctuations in the value of securities held in our securities portfolio; (xiii) concentrations within our loan portfolio, large loans to certain borrowers, and large deposits from certain clients; (xiv) the concentration of large deposits from certain clients who have balances above current FDIC insurance limits and may withdraw deposits to diversify their exposure; (xv) the level of non-performing assets on our balance sheets; (xvi) interruptions involving our information technology and communications systems or third-party servicers; (xvii) breaches or failures of our information security controls or cybersecurity-related incidents; and (xviii) the economic impact of exceptional weather occurrences such as tornadoes, hurricanes, floods, blizzards, and droughts. These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements. Additional information concerning Busey and our business, including additional factors that could materially affect our financial results, is included in our filings with the SEC.

CRITICAL ACCOUNTING ESTIMATES

Busey has established various accounting policies that govern the application of GAAP in the preparation of its unaudited consolidated financial statements. Significant accounting policies are described in “Note 1. Significant Accounting Policies” of Busey’s 2022 Annual Report.

Critical accounting estimates are those that are critical to the portrayal and understanding of Busey’s financial condition and results of operations and require management to make assumptions that are difficult, subjective, or complex. These estimates involve judgments, assumptions, and uncertainties that are susceptible to change. In the event that different assumptions or conditions were to prevail, and depending on the severity of such changes, the possibility of a materially different financial condition or materially different results of operations is a reasonable likelihood. Further, changes in accounting standards could impact our critical accounting estimates. Management has reviewed these critical accounting estimates and related disclosures with our Audit Committee. The following accounting policies could be deemed critical:

Fair Value of Debt Securities Available for Sale

Fair values of debt securities available for sale are measurements from an independent pricing service and are based on observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other things. Different fair value estimates could result from the use of different judgments and estimates to determine the fair values of securities.

Realized securities gains or losses are reported in the unaudited Consolidated Statements of Income. The cost of securities sold is based on the specific identification method.

85

A debt security available for sale is impaired if the fair value of the security declines below its amortized cost basis. To determine the appropriate accounting, we must first determine if we intend to sell the security or if it is more likely than not that we will be required to sell the security before the fair value increases to at least the amortized cost basis. If either of those selling events is expected, we will write down the amortized cost basis of the security to its fair value. This is achieved by writing off any previously recorded allowance related to the debt security, if applicable, and recognizing any incremental impairment through earnings. If we do not intend to sell the security, nor believe it more likely than not that we will be required to sell the security before the fair value recovers to the amortized cost basis, we must determine whether any of the decline in fair value has resulted from a credit loss, or if it is entirely the result of noncredit factors.

We consider the following factors in assessing whether the decline is due to a credit loss:

•Extent to which the fair value is less than the amortized cost basis;

•Adverse conditions specifically related to the security, an industry, or a geographic area (for example, changes in the financial condition of the issuer of the security, or in the case of an asset-backed debt security, in the financial condition of the underlying loan obligors);

•Payment structure of the debt security and the likelihood of the issuer being able to make payments that increase in the future;

•Failure of the issuer of the security to make scheduled interest or principal payments; and

•Any changes to the rating of the security by a rating agency.

Impairment related to a credit loss must be measured using the discounted cash flow method. Credit loss recognition is limited to the fair value of the security. Impairment is recognized by establishing an allowance for the debt security through the provision for credit losses. Impairment related to noncredit factors is recognized in AOCI, net of applicable taxes.

Fair Value of Assets Acquired and Liabilities Assumed in Business Combinations

Business combinations are accounted for using the acquisition method of accounting. Under the acquisition method of accounting, assets acquired and liabilities assumed are recorded at their estimated fair value on the date of acquisition. Fair values are determined based on the definition of “fair value” defined in ASC Topic 820 “Fair Value Measurement” as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.”

The fair value of a loan portfolio acquired in a business combination generally requires greater levels of management estimates and judgment than other assets acquired or liabilities assumed. Acquired loans are in the scope of ASC Topic 326 “Financial Instruments—Credit Losses.” However, the offset to record the allowance on acquired loans at the date of acquisition depends on whether or not the loan is classified as PCD. The allowance for PCD loans is recorded through a gross-up effect, while the allowance for acquired non-PCD loans is recorded through provision expense, consistent with originated loans. Thus, the determination of which loans are PCD and non-PCD can have a significant effect on the accounting for these loans.

Goodwill

Goodwill represents the excess of purchase price over the fair value of net assets acquired using the acquisition method of accounting. Determining the fair value often involves estimates based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Goodwill is not amortized. Instead, we assess the potential for impairment on an annual basis or more frequently if events and circumstances indicate that goodwill might be impaired.

Income Taxes

Busey estimates income tax expense based on amounts expected to be owed to federal and state tax jurisdictions. Estimated income tax expense is reported in the unaudited Consolidated Statements of Income. Accrued and deferred taxes, as reported in other assets or other liabilities in the unaudited Consolidated Balance Sheets, represent the net estimated amount due to or to be received from taxing jurisdictions either currently or in the future. Management judgment is involved in estimating accrued and deferred taxes, as it may be necessary to evaluate the risks and merits of the tax treatment of transactions, filing positions, and taxable income calculations after considering tax-related statutes, regulations, and other relevant factors. Because of the complexity of tax laws and interpretations, interpretation is subject to judgment.

Allowance for Credit Losses

Busey calculates the ACL at each reporting date. We recognize an allowance for the lifetime expected credit losses for the amount we do not expect to collect. Measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported book value. The calculation also contemplates that Busey may not be able to make or obtain such forecasts for the entire life of the financial assets and requires a reversion to historical credit loss information.

In determining the ACL, management relies predominantly on a disciplined credit review and approval process that extends to the full range of Busey’s credit exposure. The ACL must be determined on a collective (pool) basis when similar risk characteristics exist. On a case-by-case basis, we may conclude a loan should be evaluated on an individual basis based on disparate risk characteristics.

Loans deemed uncollectible are charged against and reduce the ACL. A provision for credit losses is charged to current expense and acts to replenish the ACL in order to maintain the ACL at a level that management deems adequate. Determining the ACL involves significant judgments and assumptions by management. Because of the nature of the judgments and assumptions made by management, actual results may differ from these judgments and assumptions.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the risk of changes in asset values due to movements in underlying market rates and prices. Interest rate risk is a type of market risk to earnings and capital arising from movements in interest rates. Interest rate risk is the most significant market risk affecting Busey as other types of market risk, such as foreign currency exchange rate risk and commodity price risk, have minimal impact or do not arise in the normal course of Busey’s business activities.

Busey has an asset-liability committee, whose policy is to meet at least quarterly, to review current market conditions and to structure the Consolidated Balance Sheets to optimize stability in net interest income in consideration of projected future changes in interest rates.

As interest rate changes do not impact all categories of assets and liabilities equally or simultaneously, the asset-liability committee primarily relies on balance sheet and income simulation analysis to determine the potential impact of changes in market interest rates on net interest income. In these standard simulation models, the balance sheet is projected over a one-year and a two-year time horizon and net interest income is calculated under current market rates and assuming permanent instantaneous shifts of +/-100, +/-200, +/-300, and +/-400 basis points. The model assumes immediate and sustained shifts in the federal funds rate and other market rate indices and corresponding shifts in other non-market rate indices based on their historical changes relative to changes in the federal funds rate and other market indices. Assets and liabilities are assumed to remain constant as of the measurement date; variable-rate assets and liabilities are repriced based on repricing frequency; and prepayment speeds on loans are projected for both declining and rising rate environments.

Busey’s interest rate risk resulting from immediate and sustained changes in interest rates, expressed as a change in net interest income as a percentage of the net interest income calculated in the constant base model, was as follows:

	Year-One: Basis Point Changes
	-400		-300	-200		- 100	+100	+200	+300	+400
June 30, 2023	(11.34)	%	(8.16)%	(5.12)	%	(2.61)%	2.20%	4.45%	6.71%	8.99%
December 31, 2022	(21.24)	%	(14.74)%	(8.08)	%	(3.95)%	3.05%	6.11%	9.18%	12.27%

87

	Year-Two: Basis Point Changes
	-400		-300	-200		- 100	+100	+200	+300	+400
June 30, 2023	(15.99)	%	(11.32)%	(6.97)	%	(3.51)%	2.53%	5.15%	7.82%	10.54%
December 31, 2022	(27.82)	%	(19.56)%	(10.76)	%	(5.27)%	3.94%	7.91%	11.94%	16.02%

Interest rate risk is monitored and managed within approved policy limits and any temporary exceptions to policy in periods of rapid rate movement are approved and documented. The calculation of potential effects of hypothetical interest rate changes is based on numerous assumptions and should not be relied upon as indicative of actual results. Actual results would likely differ from simulated results due to the timing, magnitude, and frequency of interest rate changes as well as changes in market conditions and management strategies.

ITEM 4. CONTROLS AND PROCEDURES

Basis of Financial Statement Presentation

These unaudited consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements included in Busey's 2022 Annual Report. These interim unaudited consolidated financial statements serve to update our 2022 Annual Report and may not include all information and notes necessary to constitute a complete set of financial statements.

We prepared these unaudited consolidated financial statements in conformity with GAAP. We have eliminated intercompany accounts and transactions. We have also reclassified certain prior year amounts to conform to the current period presentation. These reclassifications did not have a material impact on our consolidated financial condition or results of operations.

In our opinion, the unaudited consolidated financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

Use of Estimates

In preparing the accompanying unaudited consolidated financial statements in conformity with GAAP, Busey’s management is required to make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures provided. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of debt securities available for sale, fair value of assets acquired and liabilities assumed in business combinations, goodwill, income taxes, and the determination of the ACL.

Impact of Recently Adopted Accounting Standards

In March 2022, the FASB issued ASU 2022-02 “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures,” which eliminates the TDR accounting model for creditors that have already adopted CECL. In lieu of the TDR accounting model, loan refinancing and restructuring guidance in ASC Subtopic 310-20-35-9 through 35-11 “Receivables—Nonrefundable Fees and Other Costs—Subsequent Measurement—Loan Refinancing or Restructuring” will apply to all loan modifications, including those made for borrowers experiencing financial difficulty. This standard also enhances disclosure requirements related to certain loan modifications. Additionally, this standard introduces new requirements to disclose gross write-off information in the vintage disclosures of financing receivables by credit quality indicator and class of financing receivable by year of origination. This standard applies prospectively. For the transition method related to the recognition and measurement of TDRs, there is an option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. This standard became effective for Busey beginning January 1, 2023. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations.

In March 2022, the FASB issued ASU 2022-01 “Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method,” which replaces the current last-of-layer hedge accounting method with an expanded portfolio layer method that permits multiple hedged layers of a single closed portfolio. The scope of the portfolio layer method is also expanded to include non-prepayable financial assets. This update also provides additional guidance on the accounting for and disclosure of hedge basis adjustments that are applicable to the portfolio layer method, and specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. Amendments related to hedge basis adjustments which are included in this standard apply on a modified retrospective basis by means of a cumulative-effect adjustment to the opening balance of retained earnings on the initial application date. Amendments related to disclosure which are included in this standard may be applied on a prospective basis from the initial application date, or on a retrospective basis to each prior period presented after the date of adoption of the amendments in ASU 2017-12 “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” This standard became effective for Busey beginning January 1, 2023. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations.

ASU 2021-08 “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” requires measurement and recognition in accordance with ASC Topic 606 “Revenue from Contracts with Customers” for contract assets and contract liabilities acquired in a business combination. This update became effective for Busey beginning January 1, 2023. This standard applies prospectively to all business combinations that occur on or after the date it is adopted. Adoption of this standard did not have an impact on Busey’s financial position or results of operations.

Recently Issued Accounting Standards Not Yet Adopted

In March 2023, the FASB issued ASU 2023-02 “Investments—Equity Method and Joint Ventures (Topic 323),” permitting an election to use the proportional amortization method to account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits, regardless of the tax credit program from which the income tax credits are received, provided that certain conditions are met. The proportional amortization method results in the cost of the investment being amortized in proportion to the income tax credits and other income tax benefits received, with the amortization of the investment and the income tax credits being presented net in the income statement as a component of income tax expense. This standard must be applied on a retrospective or modified retrospective basis, and is applicable for Busey beginning on January 1, 2024. Early adoption is permitted. Busey is currently evaluating the potential effect on the Company’s financial position and results of operations, and upon adoption expects changes to be reflected in the Other Expense and Income Taxes line items in the Consolidated Statements of Income.

In March 2023, the FASB issued ASU 2023-01 “Leases (Topic 842): Common Control Arrangements,” which requires amortization over the useful life of leasehold improvements (not the lease term) when the lease is between entities under common control, and any value of such leasehold improvements remaining at the end of the lease term is to be accounted for as a transfer between entities under common control. This standard may be adopted either prospectively, or retrospectively, and is effective for Busey beginning January 1, 2024. Early adoption is permitted. Busey is currently evaluating the potential effect on the Company’s financial position and results of operations.

In June 2022, the FASB issued ASU 2022-03 “Fair Value Measurements (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions,” which clarifies that contractual restrictions on the sale of equity securities are not considered in measuring the fair value of those equity securities, and further that contractual sale restrictions cannot be recognized and measured as a separate unit of account. This standard applies prospectively, and is effective for Busey beginning January 1, 2024. Early adoption is permitted. Busey is currently evaluating the potential effect on the Company’s financial position and results of operations.

Subsequent Events

Busey has evaluated subsequent events for potential recognition and/or disclosure through the date the unaudited consolidated financial statements included in this Quarterly Report were issued. There were no significant subsequent events for the quarter ended June 30, 2023, through the filing date of these unaudited consolidated financial statements.

Unrealized and unrecognized losses were related to changes in market interest rates and market conditions that do not represent credit-related impairments. Busey does not intend to sell securities that are in an unrealized or unrecognized loss position, and it is more likely than not that the Company will recover the amortized cost prior to being required to sell the debt securities. Full collection of the amounts due according to the contractual terms of the debt securities is expected; therefore, no ACL was recorded in relation to debt securities, and the impairment related to noncredit factors is recognized in AOCI, net of applicable taxes. As of June 30, 2023, Busey did not hold general obligation bonds of any single issuer, the aggregate of which exceeded 10% of the Company’s stockholders’ equity.

Distributions of the loan portfolio by loan category and class is presented in the following table (dollars in thousands):

Net deferred loan origination costs included in the balances above were $13.4 million as of June 30, 2023, compared to $14.0 million as of December 31, 2022. Net accretable purchase accounting adjustments included in the balances above reduced loans by $5.1 million as of June 30, 2023, and $5.9 million as of December 31, 2022. Commercial balances include loans originated under the PPP with an amortized cost of $0.7 million as of June 30, 2023, and $0.8 million as of December 31, 2022.

Busey did not purchase any retail real estate loans during the three or six months ended June 30, 2023, or 2022.

Pledged Loans

	As of
	June 30, 2023		December 31, 2022

Risk Grading

Busey utilizes a loan grading scale to assign a risk grade to all of its loans. A description of the general characteristics of each grade is as follows:

•Pass – This category includes loans that are all considered acceptable credits, ranging from investment or near investment grade, to loans made to borrowers who exhibit credit fundamentals that meet or exceed industry standards.

•Watch – This category includes loans that warrant a higher-than-average level of monitoring to ensure that weaknesses do not cause the inability of the credit to perform as expected. These loans are not necessarily a problem due to other inherent strengths of the credit, such as guarantor strength, but have above average concern and monitoring.

•Special mention – This category is for “Other Assets Specially Mentioned” loans that have potential weaknesses, which may, if not checked or corrected, weaken the asset or inadequately protect the Company’s credit position at some future date.

•Substandard – This category includes “Substandard” loans, determined in accordance with regulatory guidelines, for which the accrual of interest has not been stopped. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

•Substandard non-accrual – This category includes loans that have all the characteristics of a “Substandard” loan with additional factors that make collection in full highly questionable and improbable. Such loans are placed on non-accrual status and may be dependent on collateral with a value that is difficult to determine.

All loans are graded at their inception. Commercial lending relationships that are $1.0 million or less are usually processed through an expedited underwriting process. Most commercial loans greater than $1.0 million are included in a portfolio review at least annually. Commercial loans greater than $0.35 million that have a grading of special mention or worse are typically reviewed on a quarterly basis. Interim reviews may take place if circumstances of the borrower warrant a more frequent review.

The following table is a summary of risk grades segregated by category and class of portfolio loans (dollars in thousands):

Gross interest income recorded on 90+ days past due loans, and that would have been recorded on non-accrual loans if they had been accruing interest in accordance with their original terms, was $0.3 million and $0.7 million for the three and six months ended June 30, 2023, respectively, and was $0.3 million and $0.5 million for the three and six months ended June 30, 2022, respectively. The amount of interest collected on those loans and recognized on a cash basis that was included in interest income was insignificant for the three and six months ended June 30, 2023. Interest collected on these loans and recognized on a cash basis was insignificant for the three months ended June 30, 2022, and was $0.4 million for the six months ended June 30, 2022.

___________________________________________

1.A loan with payment deferral was modified to defer all principal payments until the end of the loan term, which was shortened.

2.Loans with payment deferrals represent an insignificant portion of commercial loans and total loans, rounding to zero percent.

3.Modifications to extend loan terms also included, in some cases, interest rate increases during the extension period.

4.Modifications include two loans on non-accrual status, one on special mention status, and the remaining loans were classified as substandard.

The following table summarizes the effects of loan modifications made during the periods indicated, for borrowers experiencing financial difficulty:

	Three Months Ended June 30, 2023	Six Months Ended June 30, 2023
	Weighted Average Term Extension	Weighted Average Term Extension
Loan class:
Commercial	11.5 months	11.4 months
Commercial real estate	6.0 months	8.2 months
Real estate construction	12.0 months	12.0 months

Busey closely monitors the performance of the loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts.

The following table depicts the payment performance of loans modified on or after January 1, 2023, the date we adopted ASU 2022-02 (dollars in thousands):

TDR Disclosures Prior to the Adoption of ASU 2022-02

At December 31, 2022, performing TDR’s were $3.0 million and non-performing TDR’s were $0.5 million.

One loan was newly designated as a TDR during the three and six months ended June 30, 2022. There were no TDRs entered into during the 12 months ended June 30, 2022, that had subsequent defaults during the three or six months ended June 30, 2022. Gross interest income that would have been recorded in the three and six months ended June 30, 2022, if TDRs had performed in accordance with their original terms compared with their modified terms, was insignificant.

Collateral Dependent Loans

Management's evaluation as to the ultimate collectability of loans includes estimates regarding future cash flows from operations and the value of property, real and personal, pledged as collateral. These estimates are affected by changing economic conditions and the economic prospects of borrowers. Collateral dependent loans are loans in which repayment is expected to be provided solely by the underlying collateral and there are no other available and reliable sources of repayment. Loans are written down to the lower of cost or fair value of underlying collateral, less estimated costs to sell. The Company had $13.6 million and $14.0 million of collateral dependent loans secured by real estate or business assets as of June 30, 2023, and December 31, 2022, respectively.

Foreclosures

As of June 30, 2023, Busey had $1.1 million of residential real estate in the process of foreclosure. Busey follows Federal Housing Finance Agency guidelines on single-family foreclosures and real estate owned evictions on portfolio loans.

Loans Evaluated Individually

Busey evaluates loans with disparate risk characteristics on an individual basis. The following tables provide details of loans evaluated individually, segregated by loan category and class. The unpaid principal balance represents customer outstanding contractual principal balances excluding any partial charge-offs. Recorded investment represents the amortized cost of customer balances net of any partial charge-offs recognized on the loan.

Borrowings

Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase, which are classified as secured borrowings, generally mature daily. Securities sold under agreements to repurchase are reflected at the amount of cash received in connection with the transaction. The underlying securities are held by Busey’s safekeeping agent. Busey may be required to provide additional collateral based on fluctuations in the fair value of the underlying securities. Securities sold under agreements to repurchase were as follows (dollars in thousands):

	As of
	June 30, 2023			December 31, 2022
Securities sold under agreements to repurchase	$	202,953		$	229,806
Weighted average rate for securities sold under agreements to repurchase	2.64		%	1.91		%

Term Loan

On May 28, 2021, Busey entered into a Second Amended and Restated Credit Agreement, pursuant to which Busey has access to (i) a $40.0 million revolving line of credit with a termination date of April 30, 2022, and (ii) a $60.0 million term loan with a maturity date of May 31, 2026. The loans had an annual interest rate of 1.75% plus the one-month LIBOR rate. On April 30, 2022, the agreement was amended, effecting an extension of the termination date for the revolving line of credit to April 30, 2023, and providing for the transition from a LIBOR-indexed interest rate to a SOFR-indexed interest rate. Under the terms of the amendment, the loans now have an annual interest rate of 1.80% plus the one-month forward-looking term rate based on SOFR. On April 30, 2023, the agreement was further amended to extend the term for the revolving line of credit to April 30, 2024.

Proceeds of the term loan were used to fund a part of the cash portion of the merger consideration related to the acquisition of CAC in the second quarter of 2021, and for general corporate purposes. As of June 30, 2023, there was no balance outstanding on the revolving credit facility and a total of $36.0 million outstanding on the term loan, of which $12.0 million was short-term and $24.0 million was long-term. The revolving credit facility incurs a non-usage fee based on any undrawn amounts. Quarterly payments on the term loan reduce the outstanding principal balance by $3.0 million each quarter.

Short-term Borrowings

Busey’s short-term borrowings include loans maturing within one year of the loan origination date, as well as the current portion of long-term debt that is due within 12 months. Short-term borrowings are summarized as follows (dollars in thousands):

Senior and Subordinated Notes

On June 1, 2020, Busey issued $125.0 million of fixed-to-floating rate subordinated notes that mature on June 1, 2030. The subordinated notes, which qualify as Tier 2 capital for Busey, bear interest at an annual rate of 5.25% for the first five years after issuance and thereafter bear interest at a floating rate equal to a three-month benchmark rate plus a spread of 5.11%, as calculated on each applicable determination date. Interest on the subordinated notes is payable semi-annually on each June 1 and December 1 during the five-year fixed-term, and thereafter on March 1, June 1, September 1, and December 1 of each year, commencing on September 1, 2025. The subordinated notes have an optional redemption, in whole or in part, on any interest payment date on or after June 1, 2025. The subordinated notes are unsecured obligations of the Company.

On June 2, 2022, Busey issued $100.0 million aggregate principal amount of 5.000% fixed-to-floating rate subordinated notes maturing June 15, 2032, which qualify as Tier 2 capital for regulatory purposes. The price to the public for the subordinated notes was 100% of the principal amount of the subordinated notes. Interest on the subordinated notes accrues at a rate equal to (i) 5.000% per annum from the original issue date to, but excluding, June 15, 2027, payable semiannually in arrears, and (ii) a floating rate per annum equal to a benchmark rate, which is expected to be the Three-Month Term SOFR (as defined in the subordinated notes), plus a spread of 252 basis points from and including, June 15, 2027, payable quarterly in arrears. The subordinated notes have an optional redemption, in whole or in part, on any interest payment date on or after June 15, 2027.

Regulatory Capital

Regulatory Capital

First Busey Corporation and Busey Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory—and possibly additional discretionary—actions by regulators that, if undertaken, could have a direct material effect on Busey's consolidated financial statements. Capital amounts and classification also are subject to qualitative judgments by regulators about components, risk weightings, and other factors.

Banking regulations identify five capital categories for insured depository institutions: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. As of June 30, 2023, and December 31, 2022, all capital ratios of First Busey Corporation and Busey Bank exceeded well capitalized levels under the applicable regulatory capital adequacy guidelines. Management believes that no events or changes have occurred subsequent to June 30, 2023, that would change this designation.

Current Expected Credit Loss Model

On August 26, 2020, the FDIC and other federal banking agencies adopted a final rule which provided banking organizations that adopted CECL during 2020 with the option to delay for two years the estimated impact of CECL on regulatory capital and to phase in the aggregate impact of the deferral on regulatory capital over a subsequent three-year period. Under this final rule, because the Company has elected to use the deferral option, the regulatory capital impact of our transition adjustments recorded on January 1, 2020, arising from the adoption of CECL, was deferred for two years. In addition, 25 percent of the ongoing impact of CECL on our ACL, retained earnings, and average total consolidated assets from January 1, 2020, through the end of the two-year deferral period, each as reported for regulatory capital purposes, has been added to the deferred transition amounts (“adjusted transition amounts”) and deferred for the two-year period. On January 1, 2022, at the conclusion of the two-year period, the adjusted transition amounts began to be phased-in for regulatory capital purposes at a rate of 25 percent per year, with the phased-in amounts included in regulatory capital at the beginning of each year.

Capital Conservation Buffer

In July 2013, U.S. federal banking authorities approved the Basel III Rule for strengthening international capital standards. The Basel III Rule introduced a capital conservation buffer, composed entirely of common equity Tier 1 capital, which is added to the minimum risk-weighted asset ratios. The capital conservation buffer is not a minimum capital requirement; however, banking institutions with a ratio of common equity Tier 1 capital to risk-weighted assets below the capital conservation buffer will face constraints on dividends, equity repurchases, and discretionary bonus payments based on the amount of the shortfall. In order to refrain from restrictions on dividends, equity repurchases, and discretionary bonus payments, banking institutions must maintain minimum ratios of (i) common equity Tier 1 capital to risk-weighted assets of at least 7.0%, (ii) Tier 1 capital to risk-weighted assets of at least 8.5%, and (iii) total capital to risk-weighted assets of at least 10.5%.

The Amended 2020 Equity Plan was approved by stockholders at the 2023 Annual Meeting of Stockholders. The terms of the Amended 2020 Equity Plan are substantially identical to those of the stockholder approved 2020 Equity Plan, other than an increase of 1,350,000 in the number of shares authorized for issuance under the plan. More information can be found in Busey’s Proxy Statement for the 2023 Annual Meeting of Stockholders filed on April 14, 2023.

RSU Awards

Busey grants RSUs to members of management periodically throughout the year. Each RSU is equivalent to one share of Busey’s common stock.

Recipients earn quarterly dividend equivalents on their respective units which entitle the recipients to additional units. Therefore, dividends earned each quarter compound based upon the updated unit balances.

On March 22, 2023, under the terms of the 2020 Equity Plan, Busey granted 224,316 RSUs to members of management. The grant date fair value of the award totaled $4.6 million and will be recognized as compensation expense over the requisite service period ranging from one year to five years. The terms of these awards included an accelerated vesting provision upon eligible retirement from the Company, after a one-year minimum requisite service period.

PSU Awards

Busey grants PSUs, which are restricted stock units that are subject to certain performance criteria, to members of management periodically throughout the year. Each PSU is equivalent to one share of Busey’s common stock.

On March 22, 2023, under the terms of the 2020 Equity Plan, Busey granted a target of 104,643 PSUs with a maximum award of 167,429 units. The actual number of units issued at the vesting date could range from 0% to 160% of the initial grant, depending on attaining a market-based total stockholder return performance goal. The grant date fair value of the award was $2.0 million and will be recognized in compensation expense over the performance period ending December 31, 2025.

On March 22, 2023, under the terms of the 2020 Equity Plan, Busey granted a target of 104,643 PSUs with a maximum award of 167,429 units.

DSU Awards

Busey grants DSUs, which are restricted stock units with a deferred settlement date, to its directors and advisory directors. Each DSU is equivalent to one share of Busey’s common stock. DSUs vest over a one-year period following the grant date. Under both the 2020 Equity Plan and the Amended 2020 Equity Plan, DSUs are generally are subject to the same terms as RSUs, except that following vesting of DSUs, settlement occurs within 30 days following the earlier of separation from the board or a change in control of the Company.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial InstrumentsBusey utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. Additionally, Busey enters into derivative financial instruments, including interest rate lock commitments issued to residential loan customers for loans that will be held for sale, forward sales commitments to sell residential mortgage loans to investors, and interest rate swaps and foreign currency exchange contracts with customers and other third parties. See “Note 11: Fair Value Measurements” for further discussion of the fair value measurement of such derivatives.

To secure its obligations under derivative contracts, Busey pledged cash and held collateral as follows (dollars in thousands):

	As of
	June 30, 2023		December 31, 2022
Cash pledged to secure obligations under derivative contracts	$	34,210	$	38,609
Collateral held to secure obligations under derivative contracts	27,670		29,830

Derivative Instruments Designated as Hedges

Busey entered into derivative instruments designated as cash flow hedges. For a derivative instrument that is designated and qualifies as a cash flow hedge, the change in fair value of the derivative instrument is reported as a component of OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Changes in fair value of components excluded from the assessment of effectiveness are recognized in current earnings.

Interest Rate Swaps Designated as Cash Flow Hedges

Interest rate swaps with notional amounts totaling $350.0 million as of both June 30, 2023, and December 31, 2022, were designated as cash flow hedges. Busey entered into one $50.0 million interest rate swap to hedge the risks of variability in cash flows for future interest payments attributable to changes in the contractually specified 3-month LIBOR benchmark interest rate on the Busey’s junior subordinated debt owed to unconsolidated trusts (Debt Swap). In addition, Busey entered into one $300.0 million receive fixed pay floating interest rate swap to reduce Busey’s asset sensitivity (Loan Swap). Duration was added to our loan portfolio by fixing a portion of floating prime based loans. Interest rates had risen above their historical lows allowing Busey to lock in a portion of its loan portfolio to reduce asset sensitivity while creating a more stable margin in a volatile rate market. These hedges were determined to be highly effective during the period, and Busey expects its hedges to remain highly effective during the remaining terms of the swaps. Changes in fair value were recorded net of tax in OCI.

A summary of the interest-rate swaps designated as cash flow hedges is presented below (dollars in thousands):

Derivative Instruments Not Designated as Hedges

Interest Rate Swaps Not Designated as Hedges

Busey may offer derivative contracts to its customers in connection with their risk management needs. Busey manages the risk associated with these contracts by entering into equal and offsetting derivative agreements with a third-party dealer. These contracts support variable rate, commercial loan relationships totaling $623.2 million as of June 30, 2023, and $576.9 million as of December 31, 2022. These derivatives generally work together as an economic interest rate hedge, but Busey did not designate them for hedge accounting treatment. Consequently, changes in fair value of the corresponding derivative financial asset or liability are recorded as either a charge or credit to current earnings during the period in which the changes occurred.

Amounts and fair values of derivative assets and liabilities related to customer interest rate swaps recorded in the Consolidated Balance Sheets are summarized as follows (dollars in thousands):

Foreign Currency Forward Contracts

Busey entered into foreign currency exchange contracts to support the business requirements of its customers. Foreign currency contracts involve the exchange of one currency for another on a specified date and at a specified rate. These contracts are executed on behalf of the Busey's customers and are used by customers to manage fluctuations in foreign exchange rates. Busey minimizes its exposure by entering into similar offsetting positions with other financial institutions. Busey is subject to the credit risk that another party will fail to perform. Amounts and fair values of derivative assets and liabilities related to foreign currency contracts recorded in the Consolidated Balance Sheets are summarized as follows (dollars in thousands):

Mortgage Banking Derivatives

Interest Rate Lock Commitments

Interest rate lock commitments that meet the definition of derivative financial instruments under ASC Topic 815 “Derivatives and Hedging” are carried at their fair values in other assets or other liabilities in the Consolidated Balance Sheets, with changes in the fair values of the corresponding derivative financial assets or liabilities recorded as either a charge or credit to current earnings during the period in which the changes occurred.

Forward Sales Commitments

Busey economically hedges mortgage loans held for sale and interest rate lock commitments issued to its residential loan customers related to loans that will be held for sale by obtaining corresponding forward sales commitments with an investor to sell the loans at an agreed-upon price at the time the interest rate locks are issued to the customers. Forward sales commitments that meet the definition of derivative financial instruments under ASC Topic 815 “Derivatives and Hedging” are carried at their fair values in other assets or other liabilities in the Consolidated Balance Sheets. While such forward sales commitments generally served as an economic hedge to mortgage loans held for sale and interest rate lock commitments, Busey did not designate them for hedge accounting treatment. Changes in fair value of the corresponding derivative financial asset or liability were recorded as either a charge or credit to current earnings during the period in which the changes occurred.

Amounts and fair values of mortgage banking derivatives included in the Consolidated Balance Sheets are summarized as follows (dollars in thousands):

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The fair value of an asset or liability is the price that would be received by selling that asset or paid in transferring that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. ASC Topic 820 “Fair Value Measurement” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

•Level 1 Inputs—Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

•Level 2 Inputs—Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

•Level 3 Inputs—Unobservable inputs for determining the fair values of assets or liabilities that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to those Company assets and liabilities that are carried at fair value.

In general, fair value is based upon quoted market prices, when available. If such quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable data. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect, among other things, counterparty credit quality and the company's creditworthiness as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. While management believes Busey's valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

Financial Assets and Financial Liabilities Measured at Fair Value on a Recurring Basis

Debt Securities Available for Sale

Debt securities classified as available for sale are reported at fair value utilizing Level 2 inputs. Busey obtains fair value measurements from an independent pricing service. The independent pricing service utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid, and other market information. Because many fixed income securities do not trade on a daily basis, the independent pricing service applies available information, focusing on observable market data such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations.

The independent pricing service uses model processes, such as the Option Adjusted Spread model, to assess interest rate impact and develop prepayment scenarios. Models and processes take into account market conventions. For each asset class, a team of evaluators gathers information from market sources and integrates relevant credit information, perceived market movements, and sector news into the evaluated pricing applications and models.

Market inputs that the independent pricing service normally seeks for evaluations of securities, listed in approximate order of priority, include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications. The independent pricing service also monitors market indicators, industry, and economic events. For certain security types, additional inputs may be used or some of the market inputs may not be applicable. Evaluators may prioritize inputs differently on any given day for any security based on market conditions, and not all inputs listed are available for use in the evaluation process for each security evaluation on a given day. Because the data utilized was observable, the securities have been classified as Level 2.

Equity Securities

Equity securities are reported at fair value utilizing Level 1 or Level 2 inputs. Fair value measurements of mutual funds, when held, are determined using unadjusted quoted prices in active markets for identical assets at the measurement date and are classified as Level 1. Fair value measurements of stock utilize quoted prices for identical or similar assets in markets that are not active and are classified as Level 2.

Derivative Assets and Derivative Liabilities

The majority of our derivative assets and derivative liabilities are reported at fair value utilizing Level 2 or Level 3 inputs. Fair values of derivative assets and liabilities are determined based on prices that are obtained from a third-party which uses observable market inputs and, with the exception of our risk participation agreements, are classified as Level 2. Due to the significance of unobservable inputs, derivative assets related to our risk participation agreements are classified as Level 3.

The following tables summarize financial assets and financial liabilities measured at fair value on a recurring basis as of June 30, 2023, and December 31, 2022, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).

Loans Evaluated Individually

Busey does not record portfolio loans at fair value on a recurring basis. However, periodically, a loan is evaluated individually and is reported at the fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. If the collateral value is not sufficient, a specific reserve is recorded. Collateral values are estimated using a combination of observable inputs, including recent appraisals, and unobservable inputs based on customized discounting criteria. Due to the significance of unobservable inputs, fair values of individually evaluated collateral dependent loans have been classified as Level 3.

OREO and Other Repossessed Assets

Non-financial assets measured at fair value, upon initial recognition or subsequent impairment, include OREO and other repossessed assets. OREO properties and other repossessed assets are measured using a combination of observable inputs, including recent appraisals, and unobservable inputs. Due to the significance of unobservable inputs, the fair values of all OREO and other repossessed assets have been classified as Level 3.

Bank Property Held for Sale

Bank property held for sale represents certain banking center office buildings which Busey has closed and consolidated with other existing banking centers. Bank property held for sale is measured at the lower of amortized cost or fair value less estimated costs to sell. Fair values were based upon discounted appraisals or real estate listing prices. Due to the significance of unobservable inputs, fair values of all bank property held for sale have been classified as Level 3.

The following tables summarize assets and liabilities measured at fair value on a non-recurring basis for the periods presented, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

Earnings Per Common Share

Earnings Per Common Share

Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding, which include DSUs that are vested but not delivered. Diluted earnings per common share is computed using the treasury stock method and reflects the potential dilution that could occur if Busey’s outstanding stock options and warrants were exercised, stock units were vested, and ESPP shares were issued.

Earnings per common share have been computed as follows (dollars in thousands, except per share amounts):

Basis of Financial Statement Presentation

Basis of Financial Statement Presentation

These unaudited consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements included in Busey's 2022 Annual Report. These interim unaudited consolidated financial statements serve to update our 2022 Annual Report and may not include all information and notes necessary to constitute a complete set of financial statements.

We prepared these unaudited consolidated financial statements in conformity with GAAP. We have eliminated intercompany accounts and transactions. We have also reclassified certain prior year amounts to conform to the current period presentation. These reclassifications did not have a material impact on our consolidated financial condition or results of operations.

In our opinion, the unaudited consolidated financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

Use of Estimates

Use of Estimates

In preparing the accompanying unaudited consolidated financial statements in conformity with GAAP, Busey’s management is required to make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures provided. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of debt securities available for sale, fair value of assets acquired and liabilities assumed in business combinations, goodwill, income taxes, and the determination of the ACL.

Impact of Recently Adopted Accounting Standards

Impact of Recently Adopted Accounting Standards

In March 2022, the FASB issued ASU 2022-02 “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures,” which eliminates the TDR accounting model for creditors that have already adopted CECL. In lieu of the TDR accounting model, loan refinancing and restructuring guidance in ASC Subtopic 310-20-35-9 through 35-11 “Receivables—Nonrefundable Fees and Other Costs—Subsequent Measurement—Loan Refinancing or Restructuring” will apply to all loan modifications, including those made for borrowers experiencing financial difficulty. This standard also enhances disclosure requirements related to certain loan modifications. Additionally, this standard introduces new requirements to disclose gross write-off information in the vintage disclosures of financing receivables by credit quality indicator and class of financing receivable by year of origination. This standard applies prospectively. For the transition method related to the recognition and measurement of TDRs, there is an option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. This standard became effective for Busey beginning January 1, 2023. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations.

In March 2022, the FASB issued ASU 2022-01 “Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method,” which replaces the current last-of-layer hedge accounting method with an expanded portfolio layer method that permits multiple hedged layers of a single closed portfolio. The scope of the portfolio layer method is also expanded to include non-prepayable financial assets. This update also provides additional guidance on the accounting for and disclosure of hedge basis adjustments that are applicable to the portfolio layer method, and specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. Amendments related to hedge basis adjustments which are included in this standard apply on a modified retrospective basis by means of a cumulative-effect adjustment to the opening balance of retained earnings on the initial application date. Amendments related to disclosure which are included in this standard may be applied on a prospective basis from the initial application date, or on a retrospective basis to each prior period presented after the date of adoption of the amendments in ASU 2017-12 “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” This standard became effective for Busey beginning January 1, 2023. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations.

ASU 2021-08 “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” requires measurement and recognition in accordance with ASC Topic 606 “Revenue from Contracts with Customers” for contract assets and contract liabilities acquired in a business combination. This update became effective for Busey beginning January 1, 2023. This standard applies prospectively to all business combinations that occur on or after the date it is adopted. Adoption of this standard did not have an impact on Busey’s financial position or results of operations.

Recently Issued Accounting Standards Not Yet Adopted

In March 2023, the FASB issued ASU 2023-02 “Investments—Equity Method and Joint Ventures (Topic 323),” permitting an election to use the proportional amortization method to account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits, regardless of the tax credit program from which the income tax credits are received, provided that certain conditions are met. The proportional amortization method results in the cost of the investment being amortized in proportion to the income tax credits and other income tax benefits received, with the amortization of the investment and the income tax credits being presented net in the income statement as a component of income tax expense. This standard must be applied on a retrospective or modified retrospective basis, and is applicable for Busey beginning on January 1, 2024. Early adoption is permitted. Busey is currently evaluating the potential effect on the Company’s financial position and results of operations, and upon adoption expects changes to be reflected in the Other Expense and Income Taxes line items in the Consolidated Statements of Income.

In March 2023, the FASB issued ASU 2023-01 “Leases (Topic 842): Common Control Arrangements,” which requires amortization over the useful life of leasehold improvements (not the lease term) when the lease is between entities under common control, and any value of such leasehold improvements remaining at the end of the lease term is to be accounted for as a transfer between entities under common control. This standard may be adopted either prospectively, or retrospectively, and is effective for Busey beginning January 1, 2024. Early adoption is permitted. Busey is currently evaluating the potential effect on the Company’s financial position and results of operations.

In June 2022, the FASB issued ASU 2022-03 “Fair Value Measurements (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions,” which clarifies that contractual restrictions on the sale of equity securities are not considered in measuring the fair value of those equity securities, and further that contractual sale restrictions cannot be recognized and measured as a separate unit of account. This standard applies prospectively, and is effective for Busey beginning January 1, 2024. Early adoption is permitted. Busey is currently evaluating the potential effect on the Company’s financial position and results of operations.

Subsequent Events

Subsequent Events

Busey has evaluated subsequent events for potential recognition and/or disclosure through the date the unaudited consolidated financial statements included in this Quarterly Report were issued. There were no significant subsequent events for the quarter ended June 30, 2023, through the filing date of these unaudited consolidated financial statements.

___________________________________________

1.A loan with payment deferral was modified to defer all principal payments until the end of the loan term, which was shortened.

2.Loans with payment deferrals represent an insignificant portion of commercial loans and total loans, rounding to zero percent.

3.Modifications to extend loan terms also included, in some cases, interest rate increases during the extension period.

4.Modifications include two loans on non-accrual status, one on special mention status, and the remaining loans were classified as substandard.

The following table summarizes the effects of loan modifications made during the periods indicated, for borrowers experiencing financial difficulty:

	Three Months Ended June 30, 2023	Six Months Ended June 30, 2023
	Weighted Average Term Extension	Weighted Average Term Extension

The following table provides the amortized cost basis of financing receivables that had a payment default during the period and were modified in the 12 months before default for borrowers experiencing financial difficulty (dollars in thousands). A default occurs when a loan is 90 days or more past due or transferred to non-accrual status.
