Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation As used in these notes, as well as in Management's Discussion and Analysis of Financial Condition and Results of Operations, references to “the Corporation”, “Isabella”, “we”, “our”, “us”, and similar terms refer to the consolidated entity consisting of Isabella Bank Corporation and its subsidiary. References to Isabella Bank or “the Bank” refers to Isabella Bank Corporation’s subsidiary, Isabella Bank. The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with GAAP 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. In our opinion, all adjustments considered necessary for a fair presentation have been included. Operating results for the three-month period ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. For further information, refer to our Annual Report on Form 10-K for the year ended December 31, 2023. Our accounting policies are materially the same as those discussed in Note 1 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2023.
