| Amendment Description | This Form 10-K/A (this “Amendment”) amends First Trinity Financial Corporation’s (the “Company,” “our,” “we,” “us,” or similar terms) Annual Report on Form 10-K for the year ended December 31, 2022 (the “Original 10-K”), which was filed with the Securities and Exchange Commission (the “SEC”) on March 9, 2023. The Company is filing this Amendment for the purposes of correcting and providing further information to the Form 10-K. The correction relates to deleting an inadvertent carryover of a header on each page of Part III of Form 10-K, along with the signature page and exhibit list, that indicated the pages related to the Notes to the Consolidated Financial Statements for December 31, 2022 and 2021. Part III has also been revised to provide further information. We have also amended Item 5, “Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities” in Part II of the Original 10-K to provide additional disclosure. In addition, because Part III of Form 10-K was included in the Original 10-K and this Amendment, the reference on the cover page of the Original 10-K to the incorporation by reference to portions of our definitive proxy statement into Part III of the Original 10-K and this Amendment has been deleted. In connection with the filing of this Amendment and pursuant to the rules of the SEC, we are including with this Amendment new certifications of our principal executive officer and principal financial officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. Accordingly, Item 15 of Part IV has also been amended and restated to reflect the filings of these new certifications. Because no financial statements are contained within this Amendment, we are not including certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002. Except as otherwise noted, this Amendment speaks as of the filing date of the Original 10-K and reflects only the changes noted above. No other information included in the Original 10-K has been modified or updated in any way, and we have not updated the disclosures contained herein to reflect any events which occurred subsequent to the filing of the Original 10-K or to modify the disclosure contained in the Original 10-K other than to reflect the changes described above. | ||
