Accounting Policies [Abstract] |
BASIS OF PRESENTATION | BASIS OF PRESENTATION Principles of Consolidation The interim Consolidated Financial Statements include the accounts of S&T Bancorp, Inc., or S&T, and its wholly owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. Investments of 20 percent to 50 percent of the outstanding common stock of investees are accounted for using the equity method of accounting. Basis of Presentation The accompanying unaudited interim Consolidated Financial Statements of S&T have been prepared in accordance with generally accepted accounting principles, or GAAP, in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the Securities and Exchange Commission, or SEC, on February 24, 2023 (2022 Form 10-K). In the opinion of management, the accompanying interim financial information reflects all adjustments, consisting of normal recurring adjustments, necessary to present fairly our financial position and the results of operations for each of the interim periods presented. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year or any future period. Reclassification A mounts in prior period financial statements and footnotes are reclassified whenever necessary to conform to the current period presentation. Reclassifications had no effect on our results of operations or financial condition. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. Recently Adopted Accounting Standards Updates, or ASU or Updated Financial Instruments Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures In March 2022, the FASB issued ASU 2022-02, Financial Instruments Credit Losses (Topic 326): Troubled Debt Restructuring and Vintage Disclosures. The guidance eliminates the “once a TDR, always a TDR” requirement for loan disclosures and requires disclosures about the performance of modified loans to borrowers experiencing financial difficulty in the 12 months following the modification. The amendments eliminate the recognition and measurement guidance related to TDRs for creditors that have adopted ASC 326 Financial Instruments - Credit Losses. We adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, on January 1, 2020. ASC 326 requires the recognition of lifetime expected credit losses when a loan is originated or acquired, so the effect of credit losses that occur in loans modified in TDRs is already included in the allowance for credit losses. ASU 2022-02 requires a creditor to apply the loan refinancing and restructuring guidance in ASC 310-20 (consistent with the accounting for other loan modifications) to determine whether a modification results in a new loan or a continuation of an existing loan. It also requires enhanced disclosures for modifications in the form of interest rate reductions, principal forgiveness, other-than-insignificant payment delays or term extensions (or combinations thereof) of loans made to borrowers experiencing financial difficulty. Disclosures are required regardless of whether a modification of a loan to a borrower experiencing financial difficulty results in a new loan. The objective of the disclosures is to provide information about the type and magnitude of modifications and the degree of their success in mitigating potential credit losses. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, and interim periods therein. We adopted ASU 2022-02, as of January 1, 2023, using a modified retrospective transition approach. Results for reporting periods beginning after January 1, 2023 are presented under ASU 2022-02 while prior period amounts continue to be reported in accordance with previously applicable GAAP. Under the previously applicable accounting guidance, commercial TDRs were individually assessed to determine if a specific reserve was required in the allowance for credit losses, or ACL. The elimination of TDRs resulted in these loans being included in homogenous pools. The adoption of this ASU resulted in a day one cumulative effective adjustment recorded as an increase to our ACL of $0.6 million, with the offset being recorded as a decrease to retained earnings, net of tax. Refer to Note 5 Loans and Allowance for Credit Losses for additional disclosures related to modifications of loans to borrowers experiencing financial difficulty as well as gross charge-off vintage disclosures. Accounting Standards Updates Issued But Not Yet Adopted Investments Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method In March 2023, the FASB issued ASU 2023-02, Investments Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method 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. We are evaluating the accounting and disclosure requirements of ASU 2023-02 and do not expect them to have a material effect on our consolidated financial statements.
