Amendment Description	This Amendment No. 1 (the “Amendment”) on Form 10-K/A is being filed with respect to the Registrant’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the Securities and Exchange Commission on March 28, 2024 (the “Original Filing”). The Company is filing this Amendment solely to present the information required by Part III (Items 10, 11, 12, 13 and 14) of Form 10-K, which was previously omitted from the Original Filing in reliance on General Instruction G(3) to Form 10-K.   As a result of this Amendment, the Company is filing as exhibits to this Form 10-K/A the certifications required under Section 302 of the Sarbanes-Oxley Act of 2002. Because no financial statements are contained within this Form 10-K/A, the Company is not including certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002.   Except as otherwise expressly set forth herein, this Amendment (i) does not amend or otherwise update any other information in the Original Filing (ii) does not reflect events occurring after the date of the Original Filing or (iii) modify or update those disclosures that may have been affected by subsequent events. Accordingly, this Amendment should be read in conjunction with the Original Filing and with our filings with the SEC subsequent to the Original Filing.   Terms used but not otherwise defined in the Amendment have such meaning as ascribed to them in the Original Filing. Except where otherwise noted, all references to “we”, “us”, “our”, or the “Company” are to ICC Holdings, Inc. and its subsidiaries, taken together.
