Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The accompanying condensed consolidated financial statements include the accounts of CSB Bancorp, Inc. and its wholly-owned subsidiaries, The Commercial and Savings Bank (the “Bank”) and CSB Investment Services, LLC (together referred to as the “Company” or “CSB”). All significant intercompany transactions and balances have been eliminated in consolidation. The condensed consolidated financial statements have been prepared without audit. In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present fairly the Company’s financial position at March 31, 2022, and the results of operations and changes in cash flows for the periods presented have been made. Certain information and footnote disclosures typically included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been omitted. The Annual Report for CSB for the year ended December 31, 2021, contains Consolidated Financial Statements and related footnote disclosures, which should be read in conjunction with the accompanying condensed Consolidated Financial Statements. The results of operations for the periods ended March 31, 2022 are not necessarily indicative of the operating results for the full year or any future interim period. Certain items in the prior-year financial statements were reclassified to conform to the current-year presentation. Such reclassifications had no effect on net income or shareholders’ equity. USE OF ESTIMATES IN PREPARING FINANCIAL STATEMENTS In preparing the Consolidated Financial Statements, in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the Consolidated Balance Sheets and reported amounts of revenues and expenses during each reporting period. Actual results could differ from those estimates. The most significant estimates susceptible to change in the near term relate to management’s determination of the allowance for loan losses and the fair value of financial instruments. NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS ASU 2016-13 - Financial Instruments - Credit Losses. The Update and all subsequent ASU’s that modified Topic 326, requires that financial assets be presented at the net amount expected to be collected (i.e., net of expected credit losses), eliminating the probable recognition threshold for credit losses on financial assets measured at amortized cost. The measurement of expected credit losses should be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. We expect the Update will result in an increase in the allowance for credit losses for the estimated life of the financial asset, including an estimate for held-to-maturity debt securities. The amount of any increase will be impacted by the portfolio composition and quality at the adoption date, as well as economic conditions and forecasts at that time. A cumulative-effect adjustment to retained earnings is required as of the beginning of the year of adoption. The Company expects to recognize a one-time cumulative effect adjustment to the allowance for loan losses but cannot yet determine the magnitude of any such one-time adjustment or the overall impact of the new guidance on the consolidated financial statements. In November 2019, the FASB deferred the effective date for ASC 326, Financial Instruments – Credit Losses, for smaller reporting companies to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company qualifies as a smaller reporting company and does not expect to early adopt these ASU’s. ASU 2017-04 - Simplifying the Test for Goodwill Impairment. The Update, and all subsequent ASU’s, simplifies the goodwill impairment test. Under the new guidance, Step 2 of the goodwill impairment process that requires an entity to determine the implied fair value of its goodwill by assigning fair value to all its assets and liabilities is eliminated. Instead, the entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The new guidance is effective for annual and interim goodwill tests performed in fiscal years beginning after December 15, 2019. Early adoption is permitted. In November 2019, the FASB deferred the effective date for ASC 350, Intangibles – Goodwill and Other, for smaller reporting companies to fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. This Update is not expected to have a material impact on the Company’s financial statements. ASU 2020-4 – Reference Rate Reform (Topic 848). This update provides temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates, such as Secured Overnight Financing Rate. Entities can elect not to apply certain modification accounting requirements to contracts affected by what the guidance calls reference rate reform, if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. Also, entities can elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met, and can make a one-time election to sell and/or reclassify held-to-maturity debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective for all entities upon issuance through December 31, 2022. This Update is not expected to have a significant impact on the Company’s financial statements. NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) ASU 2022-02 - Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings (TDRs) and Vintage Disclosures. The amendments in this update eliminate TDR accounting for entities that have adopted Update 2016-13, while enhancing disclosure requirements for certain loan modifications by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying TDR recognition and measurement guidance, creditors will determine whether a modification results in a new loan or continuation of existing loan. These amendments are intended to enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. The ASU also requires current-period gross write-offs by year of origination within the vintage disclosures, which requires that an entity disclose the amortized cost basis of financing receivables by credit quality indicator and class of financing receivable by year of origination. The guidance is only for entities that have adopted the amendments in Update 2016-13 for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption using prospective application, including adoption in an interim period where the guidance should be applied as of the beginning of the fiscal year. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.
