(e) On May 11, 2017, Assurant, Inc. (the “Company”) held its 2017 annual meeting of stockholders (the “Annual Meeting”) and the stockholders of the Company approved the adoption of the Assurant, Inc. 2017 Long Term Equity Incentive Plan (the “2017 ALTEIP”).

A summary of the 2017 ALTEIP was included as Proposal Five in the Company’s proxy statement filed with the Securities and Exchange Commission on March 24, 2017 (the “Proxy Statement”) and is incorporated by reference herein. The summary of the 2017 ALTEIP is qualified in its entirety by reference to the full text of the 2017 ALTEIP, which is filed as Exhibit 10.1 and is incorporated by reference herein.

Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

As described in the Proxy Statement, the Board of Directors of the Company (the “Board”) approved amendments to the Amended and Restated By-laws of the Company (the “By-laws”), effective upon stockholder approval of the amendment to the Company’s certificate of incorporation (the “Charter”), which was received at the Annual Meeting, to eliminate two-thirds supermajority voting requirements. A supermajority vote of two-thirds of the Company’s outstanding common stock was required to alter, amend or repeal certain sections of the By-laws and the amendments to the By-laws reduce the supermajority voting threshold to a simple majority of shares of common stock outstanding.

In addition, on May 12, 2017, the Board approved amendments to the By-laws implementing proxy access with enhanced advance notice provisions. The amendments permit a stockholder, or a group of up to 20 stockholders, owning at least 3% of the Company’s outstanding common stock continuously for a period of at least three years to nominate and include in the Company’s proxy materials for its annual meeting of stockholders director nominees constituting up to the greater of two or 20% of the Board, provided that the stockholder(s) and nominee(s) satisfy the specified requirements. The By-laws were also amended to make certain clarifications and refinements to the advance notice provisions and implement certain other technical and administrative changes.

The foregoing summary of the amendments to the By-laws is qualified in its entirety by reference to the text of the By-laws, as amended, which is filed as Exhibit 3.2 and incorporated by reference herein.

Item 5.07. Submission of Matters to a Vote of Security Holders.
