American National Insurance Company Announces Filing Extension for Form 10-K

Galveston, Texas, March 1, 2017 – American National Insurance Company (Nasdaq: ANAT) (the “Company”) filed a Form 12b-25 Notification of Late Filing with the U.S. Securities and Exchange Commission today that discloses that the Company is unable to timely file its Form 10-K for the year ended December 31, 2016 (the “Form 10-K”) without unreasonable effort or expense. The Company anticipates that it will file its Form 10-K within the fifteen-day extension period provided by Rule 12b-25 under the Securities Exchange Act of 1934, as amended.

Additional time is needed to complete the documentation necessary to finalize the Company’s and its auditor’s assessment of the effectiveness of the Company’s internal control over financial reporting and the audit of its consolidated financial statements for the year ended December 31, 2016.

While not related to the filing extension, the Company expects to make revisions to correct immaterial errors in its financial statements for the fiscal years ended December 31, 2015 and 2014 for inclusion in the Form 10-K that will revise the previously reported consolidated balance sheets and the consolidated statements of cash flows. The Company does not expect to modify previously disclosed net income or stockholders’ equity.

The Company expects that such Form 10-K will report that, as part of its evaluation of its internal controls over financial reporting, the Company identified certain material weaknesses in its internal control over financial reporting relating to (i) the measurement of deferred income tax amounts and (ii) the reporting of collateral posted by our equity option derivatives counterparties. Although none are expected at this time, as the Company and its auditors finalize the audit process, additional adjustments and/or weaknesses could be identified. The Company is committed to remediating these material weaknesses in a timely manner. While the Company believes that progress has been made in enhancing internal controls as of December 31, 2016 and in the period since, the material weaknesses have not been fully remediated due to insufficient time to fully assess the design and operating effectiveness of the related new controls.
