Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The significant accounting policies used by Enterprise Financial Services Corp in the preparation of the condensed consolidated financial statements are summarized below: Business and Consolidation Enterprise is a financial holding company that provides a full range of banking and wealth management services to individuals and corporate customers primarily located in Arizona, California, Florida, Kansas, Missouri, Nevada, and New Mexico through its banking subsidiary, Enterprise Bank & Trust. Operating results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2023. These financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC. Basis of Financial Statement Presentation The accompanying unaudited condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with GAAP for interim financial information and pursuant to the rules and regulations of the SEC. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information presented not misleading. Except as disclosed herein, there has been no material change in the information disclosed in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated. In the opinion of management, the consolidated financial statements contain all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of the statements of financial position, results of operations, and cash flow for the interim periods. Recent Accounting Pronouncements On January 1, 2023, the Company adopted ASU 2022-02, Financial Instruments–Credit Losses (Topic 326); Troubled Debt Restructurings and Vintage Disclosures. ASU 2022-02 was issued in March 2022 and eliminates the accounting guidance on troubled debt restructurings for creditors in ASC 310-40 and amends the guidance on “vintage disclosures” to require disclosure of current-period gross charge-offs by year of origination. The ASU also updates the requirements related to accounting for credit losses under ASC 326 and adds enhanced disclosures for creditors with respect to loan refinancings and restructurings for borrowers experiencing financial difficulty. The adoption of this update did not have a material effect on the Company’s consolidated financial statements. FASB ASU 2021-01, Reference Rate Reform (Topic 848): Scope (ASU 2021-01) . ASU 2021-01 was issued in January 2021 and provides optional expedients and exceptions in ASC 848 to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendment only applies to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments will not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, where an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments in this update were effective immediately upon issuance and did not have a material effect on the consolidated financial statements. In December 2022, ASU 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset date of Topic 848 was issued, which extends the sunset date from December 31, 2022 to December 31, 2024. FASB ASU 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. ASU 2022-03 was issued in June 2022 to (1) clarify the guidance in Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, (2) amend a related illustrative example, and (3) introduce new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The Company has evaluated the accounting and disclosure requirements of ASU 2022-03 and does not expect them to have a material effect on the consolidated financial statements. FASB ASU 2023-02, Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method . ASU 2023-02 was issued in March 2023 to allow reporting entities to consistently account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits. If certain conditions are met, a reporting entity may elect to account for its tax equity investments by using the proportional amortization method regardless of the program from which it receives income tax credits, instead of only low-income-housing tax credit (“LIHTC”) structures. This amendment also eliminates certain LIHTC-specific guidance aligning the accounting with other equity investments in tax credit structures. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The Company is evaluating the accounting and disclosure requirements of ASU 2023-02 and does not expect them to have a material effect on the consolidated financial statements.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per common share data is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method. The following table presents a summary of per common share data and amounts for the periods indicated. Three months ended June 30, Six months ended June 30, (in thousands, except per share data) 2023 2022 2023 2022 Net income available to common shareholders $ 48,190 $ 44,211 $ 102,990 $ 90,675 Weighted average common shares outstanding 37,347 37,243 37,326 37,514 Additional dilutive common stock equivalents 148 39 185 58 Weighted average diluted common shares outstanding 37,495 37,282 37,511 37,572 Basic earnings per common share: $ 1.29 $ 1.19 $ 2.76 $ 2.42 Diluted earnings per common share: 1.29 1.19 $ 2.75 $ 2.41 For the three and six months ended June 30, 2023, common stock equivalents of approximately 462,000 and 411,000, respectively, were excluded from the earnings per share calculations because their effect would have been anti-dilutive. Comparatively, there were 363,000 and 319,000 common stock equivalents excluded in the prior year periods, respectively.

Such amounts are amortized over the remaining life of the securities. At June 30, 2023 and December 31, 2022, there were no holdings of securities of any one issuer in an amount greater than 10% of shareholders’ equity, other than U.S. Government agencies and sponsored enterprises. The agency mortgage-backed securities are all issued by U.S. Government agencies and sponsored enterprises. Securities having a fair value of $1.6 billion and $734.5 million at June 30, 2023 and December 31, 2022, respectively, were pledged as collateral to secure deposits of public institutions and for other purposes as required by law or contract provisions, in addition to collateral securing borrowing bases with the FHLB and the Federal Reserve. The amortized cost and estimated fair value of debt securities at June 30, 2023, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. The weighted average life of the mortgage-backed securities is approximately five years.

In 2023, the Company established an allowance for credit losses on available-for-sale investment securities through a provision for credit losses of $5.0 million and subsequently charged-off a $5.0 million investment. The charge-off related to the impairment of a debt security from a bank that failed in 2023. At each of June 30, 2023 and December 31, 2022, the Company had no allowance recorded on available-for-sale securities. Accrued interest receivable on held-to-maturity debt securities totaled $6.1 million and $5.8 million at June 30, 2023 and December 31, 2022, respectively, and is excluded from the estimate of expected credit losses. The estimate of expected credit losses considers historical credit loss information adjusted for current conditions and reasonable and supportable forecasts. The ACL on held-to-maturity securities was $0.9 million at June 30, 2023 and $0.7 million at December 31, 2022. The Company sold $28.4 million of available-for-sale securities in January 2023 for a gain of $0.4 million. There were no sales of available-for-sale securities in the three months ended June 30, 2023 nor during the three and six months ended June 30, 2022. Other Investments At June 30, 2023 and December 31, 2022, other investments totaled $66.5 million and $63.8 million, respectively. As a member of the FHLB system administered by the Federal Housing Finance Agency, the Bank is required to maintain a minimum investment in capital stock with the FHLB consisting of membership stock and activity-based stock. The FHLB capital stock of $16.0 million at June 30, 2023 and $14.0 million at December 31, 2022 is recorded at cost, which represents redemption value, and is included in other investments in the consolidated balance sheets. The remaining amounts in other investments primarily include investments in Small Business Investment Companies, Community Development Financial Institutions, private equity investments, and the Company’s investment in unconsolidated trusts used to issue trust preferred securities to third parties.

At June 30, 2023 and December 31, 2022, loans of $3.6 billion and $2.8 billion, respectively, were pledged to FHLB and the Federal Reserve Bank. Accrued interest receivable totaled $45.9 million and $48.1 million at June 30, 2023 and December 31, 2022, respectively, and was reported in “Other Assets” on the consolidated balance sheets. SBA 7(a) guaranteed loans sold during the six months ended June 30, 2023 totaled $8.8 million, resulting in a gain on sale of $0.5 million. There were no SBA loan sales during three months ended June 30, 2023 or the three and six months ended June 30, 2022.

The CECL methodology incorporates various economic scenarios. The Company utilizes three forecasts in the model: Moody’s baseline, a stronger near-term growth upside and a moderate recession downside forecast. The Company weights these scenarios at 40%, 30%, and 30%, respectively, which added approximately $14.3 million to the ACL over the baseline model at June 30, 2023. These forecasts incorporate an expectation that the Federal Reserve will continue quantitative tightening and that the terminal range of the federal funds rate will be 5.00% to 5.25% and that the recent bank failures are not an indication of a broader problem in the industry. The Company has also recognized various risks posed by loans in certain segments, including the commercial office sector, by allocating additional reserves to those segments. Some of the key risks to the forecasts that could result in future provision for credit losses are market reactions to the Federal Reserve policy actions that could push the economy into a recession, persistently higher inflation, tightening in the credit markets, and further weakness in the financial system. In addition to the CECL methodology, the Company incorporates qualitative adjustments into the ACL on loans to capture credit risks inherent within the loan portfolio that are not captured in the discounted cash flow (DCF) model. Included in these risks are 1) changes in lending policies and procedures, 2) actual and expected changes in business and economic conditions, 3) changes in the nature and volume of the portfolio, 4) changes in lending management, 5) changes in volume and the severity of past due loans, 6) changes in the quality of the loan review system, 7) changes in the value of underlying collateral, 8) the existence and effect of concentrations of credit and 9) other factors such as the regulatory, legal and competitive environments and events such as natural disasters and pandemics. At June 30, 2023, the ACL on loans included a qualitative adjustment of approximately $39.7 million. Of this amount, approximately $13.8 million was allocated to sponsor finance loans due to their mostly unsecured nature.

The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. The Company uses a probability of default/loss given default model to determine the allowance for credit losses. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. The effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance. The most common concession the Company provides to borrowers experiencing financial difficulty is a term extension. In limited circumstances, the Company may modify loans by providing principal forgiveness or an interest rate reduction. When principal forgiveness is provided, the amortized cost basis of the asset is written off against the allowance for credit losses. The amount of the principal forgiveness is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses. In some cases, the Company will modify a loan by providing multiple types of concessions. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as an interest rate reduction or principal forgiveness, may be granted. The following table shows the recorded investment at the end of the reporting period for loans modified to borrowers experiencing financial difficulty, disaggregated by loan class and type of concession granted: Term Extension Three months ended Six months ended (in thousands) June 30, 2023 Percent of Total Loan Class June 30, 2023 Percent of Total Loan Class Commercial and industrial $ 6,533 0.15 % $ 27,690 0.63 % Real estate: Commercial - owner occupied 95 — % 95 — % Construction and land development 396 0.06 % 1,138 0.17 % Residential 74 0.02 % 74 0.02 % Total $ 7,098 $ 28,997 The following table summarizes the financial impacts of loan modifications made to borrowers experiencing financial difficulty: Weighted Average Term Extension (in months) Three months ended Six months ended June 30, 2023 June 30, 2023 Commercial and industrial 5 6 Real estate: Commercial - owner occupied 3 3 Construction and land development 6 8 Residential 5 5 The following table shows the aging of the recorded investment in modified loans by class: June 30, 2023 (in thousands) Current 90 or More Total Commercial and industrial $ 27,029 $ 661 $ 27,690 Real estate: Commercial - owner occupied 95 — 95 Construction and land development 1,138 — 1,138 Residential 74 — 74 Total $ 28,336 $ 661 $ 28,997 As of June 30, 2023, commercial and industrial loans totaling $0.7 million experienced a default subsequent to being granted a term extension modification in the prior twelve months. Default is defined as movement to nonperforming status, foreclosure or charge-off. There were no loans restructured during the three or six months ended June 30, 2022, and no troubled debt restructurings subsequently defaulted during the three or six months ended June 30, 2022. The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, payment experience, credit documentation, current economic factors and other factors. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings: • Grades 1, 2, and 3 – Includes loans to borrowers with a continuous record of strong earnings, sound balance sheet condition and capitalization, ample liquidity with solid cash flow, and whose management team has experience and depth within their industry. • Grade 4 – Includes loans to borrowers with positive trends in profitability, satisfactory capitalization and balance sheet condition, and sufficient liquidity and cash flow. • Grade 5 – Includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization, liquidity, and cash flow. • Grade 6 – Includes loans to borrowers where an adverse change or perceived weakness has occurred, but may be correctable in the near future. Alternatively, this rating category may include circumstances where the borrower is starting to reverse a negative trend or condition, or has recently been upgraded from a 7, 8, or 9 rating. • Grade 7 – Special Mention credits are borrowers that experienced financial setback of a nature that is not determined to be severe or influence ‘ongoing concern’ expectations. Although possible, no loss is anticipated at this time, due to strong collateral and/or guarantor support. • Grade 8 – Substandard credits include those borrowers characterized by significant losses and sustained downward trends in balance sheet condition, liquidity, and cash flow. Repayment reliance may have shifted to secondary sources. Collateral exposure may exist and additional reserves may be warranted. • Grade 9 – Doubtful credits include borrowers that may show deteriorating trends that are unlikely to be corrected. Collateral values may appear insufficient for full recovery, therefore requiring a partial charge-off, or debt renegotiation with the borrower. The borrower may have declared bankruptcy or bankruptcy is likely in the near term. All doubtful rated credits will be on nonaccrual.

Commitments and Contingencies Disclosure [Abstract]
Commitments	COMMITMENTS AND CONTINGENT LIABILITIES The Company issues financial instruments with off balance sheet risk in the normal course of business. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company’s extent of involvement and maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. The contractual amounts of off-balance-sheet financial instruments are as follows: (in thousands) June 30, 2023 December 31, 2022 Commitments to extend credit $ 3,042,564 $ 3,113,966 Letters of credit 104,449 68,544 Off-Balance Sheet Credit Risk Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments usually have fixed expiration dates or other termination clauses, may have significant usage restrictions, and may require payment of a fee. Of the total commitments to extend credit at June 30, 2023 and December 31, 2022, approximately $253.0 million and $246.5 million, respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon or may be revoked, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate. Other liabilities includes $10.3 million and $12.1 million for estimated losses attributable to the unadvanced commitments at June 30, 2023 and December 31, 2022, respectively. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance or payment of a customer to a third party. These standby letters of credit are issued to support contractual obligations of the Company’s customers. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. As of June 30, 2023, the approximate remaining terms of standby letters of credit range from 1 month to 10 years. Contingencies The Company and its subsidiaries are, from time to time, parties to various legal proceedings arising out of their businesses. Management believes there are no such proceedings pending or threatened against the Company or its subsidiaries which, if determined adversely, would have a material adverse effect on the business, consolidated financial condition, results of operations or cash flows of the Company or any of its subsidiaries.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s borrowings. The Company does not enter into derivative financial instruments for trading purposes. Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. For hedges of variable-rate loans, interest rate swaps designated as cash flow hedges involve the receipt of fixed amounts and the Company making variable rate payments. In the fourth quarter 2022, the Company executed a cash flow hedge to reduce a portion of variability in cash flows on the Company’s prime based loan portfolio. The interest rate swap has a notional value of $100.0 million, that effectively fixes the interest rate at 6.63% for the notional amount and has a maturity date of January 1, 2028. In January 2023, the Company entered into another hedge on the prime based loan portfolio with a notional value of $50.0 million, that effectively fixes the interest rate at 6.56% for the notional amount and has a maturity date of February 1, 2027. In addition, the Company executed a prime based interest rate collar in the fourth quarter 2022 with a notional amount of $100.0 million. The collar includes a cap of 8.14% and a floor of 5.25%. This transaction, commonly referred to as a zero cost collar, involves the Company selling an interest rate cap where payments will be made when the index exceeds the cap rate, and the purchase of a floor where payments will be received if the index falls below the floor. The collar matures on October 1, 2029. For hedges of the variable-rate liabilities, interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company has executed a series of cash flow hedges to fix the effective interest rate for payments due on $62.0 million of LIBOR-based junior subordinated debentures to a weighted-average-fixed rate o f 2.62%. Select terms of the hedges are as follows: (in thousands) Notional Fixed Rate Maturity Date $ 15,465 2.60 % March 15, 2024 $ 14,433 2.60 % March 30, 2024 $ 18,558 2.64 % March 15, 2026 $ 13,506 2.64 % March 17, 2026 The gain or loss on derivatives designated and qualified as cash flow hedges of interest rate risk are recorded in accumulated other comprehensive income and subsequently reclassified into interest income or expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest income or expense as interest payments are paid on the Company’s variable-rate loans and debt. During the next twelve months, the Company estimates an additional $1.5 million will be reclassified as a decrease to interest expense and $2.9 million will be reclassified as a decrease to interest income. Non-designated Hedges Derivatives not designated as hedges are not considered speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting derivatives the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate derivatives associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings as a component of other noninterest income.

Accounting Policies [Abstract]
Business and Consolidation	Basis of Financial Statement Presentation The accompanying unaudited condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with GAAP for interim financial information and pursuant to the rules and regulations of the SEC. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information presented not misleading. Except as disclosed herein, there has been no material change in the information disclosed in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated. In the opinion of management, the consolidated financial statements contain all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of the statements of financial position, results of operations, and cash flow for the interim periods.
Recent Accounting Pronouncements	Recent Accounting Pronouncements On January 1, 2023, the Company adopted ASU 2022-02, Financial Instruments–Credit Losses (Topic 326); Troubled Debt Restructurings and Vintage Disclosures. ASU 2022-02 was issued in March 2022 and eliminates the accounting guidance on troubled debt restructurings for creditors in ASC 310-40 and amends the guidance on “vintage disclosures” to require disclosure of current-period gross charge-offs by year of origination. The ASU also updates the requirements related to accounting for credit losses under ASC 326 and adds enhanced disclosures for creditors with respect to loan refinancings and restructurings for borrowers experiencing financial difficulty. The adoption of this update did not have a material effect on the Company’s consolidated financial statements. FASB ASU 2021-01, Reference Rate Reform (Topic 848): Scope (ASU 2021-01) . ASU 2021-01 was issued in January 2021 and provides optional expedients and exceptions in ASC 848 to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendment only applies to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments will not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, where an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments in this update were effective immediately upon issuance and did not have a material effect on the consolidated financial statements. In December 2022, ASU 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset date of Topic 848 was issued, which extends the sunset date from December 31, 2022 to December 31, 2024. FASB ASU 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. ASU 2022-03 was issued in June 2022 to (1) clarify the guidance in Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, (2) amend a related illustrative example, and (3) introduce new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The Company has evaluated the accounting and disclosure requirements of ASU 2022-03 and does not expect them to have a material effect on the consolidated financial statements. FASB ASU 2023-02, Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method . ASU 2023-02 was issued in March 2023 to allow reporting entities to consistently account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits. If certain conditions are met, a reporting entity may elect to account for its tax equity investments by using the proportional amortization method regardless of the program from which it receives income tax credits, instead of only low-income-housing tax credit (“LIHTC”) structures. This amendment also eliminates certain LIHTC-specific guidance aligning the accounting with other equity investments in tax credit structures. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The Company is evaluating the accounting and disclosure requirements of ASU 2023-02 and does not expect them to have a material effect on the consolidated financial statements.
