A majority of the votes cast means that the number of votes cast &#8220;for&#8221; a director must exceed the number of votes cast &#8220;against&#8221; that director (with &#8220;abstentions&#8221; and &#8220;broker non-votes&#8221; not counted as votes cast either &#8220;for&#8221; or &#8220;against&#8221; that director&#8217;s election). In contested elections where the number of nominees exceeds the number of directors to be elected, the applicable voting standard will continue to be a plurality of the votes cast. In connection with the Majority Vote Standard, the Company also amended its Corporate Governance Guidelines (the &#8220;Guidelines&#8221;) to provide for a director resignation policy requiring that each director tender his or her resignation if he or she fails to receive the required number of votes for re-election, as discussed in further detail under Item 8.01 below.</font></div><div style="line-height:120%;text-align:left;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br></font></div><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;font-style:italic;">Other Clarifying Changes</font></div><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br></font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">Clarifying changes were made to the following provisions in the Amended By-Laws:</font></div><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br></font></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11pt;padding-left:24px;"><font style="font-family:inherit;font-size:11pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">Section 3.3 was revised to remove references to the classification of directors.</font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11pt;padding-left:24px;"><font style="font-family:inherit;font-size:11pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">References to the Senior Chairman were removed from sections 2.2, 2.8, 3.3, 3.8, 3.11, 4.1, 4.2, 6.1 and 6.3.</font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11pt;padding-left:24px;"><font style="font-family:inherit;font-size:11pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">Sections 2.7, 3.14, 5.1, 6.2 and 7.5 were revised to include updated references to the applicable sections of the Texas Business Organizations Code.</font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11pt;padding-left:24px;"><font style="font-family:inherit;font-size:11pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">Section 5.1 was revised to (i) include arbitration proceedings among the actions, suits or proceedings for which indemnification is available and (ii) include persons acting as an administrator at the request of Cullen/Frost among those eligible for indemnification.</font></div></td></tr></table><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br></font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">The foregoing description of the new by-law provisions does not purport to be complete and is qualified in its entirety by reference to the Amended By-Laws filed as Exhibit 3.2 to this Current Report on Form 8-K, which Exhibit is incorporated herein by reference.

Item 5.03    Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year
On January 28, 2016, the Board of Directors (the "Board") of Cullen/Frost Bankers, Inc. ("Cullen/Frost"), upon the recommendation of the Corporate Governance & Nominating Committee of the Board, adopted amended and restated By-Laws (the "Amended By-Laws") of Cullen/Frost. The changes from Cullen/Frost's previous By-Laws (the "Previous By-Laws") are described below.
Majority Voting
Section 2.7 of the Amended By-Laws was amended to change the voting standard for the election of directors from a plurality of the votes cast to a majority of the votes cast in uncontested elections (the "Majority Vote Standard"). A majority of the votes cast means that the number of votes cast "for" a director must exceed the number of votes cast "against" that director (with "abstentions" and "broker non-votes" not counted as votes cast either "for" or "against" that director's election). In contested elections where the number of nominees exceeds the number of directors to be elected, the applicable voting standard will continue to be a plurality of the votes cast. In connection with the Majority Vote Standard, the Company also amended its Corporate Governance Guidelines (the "Guidelines") to provide for a director resignation policy requiring that each director tender his or her resignation if he or she fails to receive the required number of votes for re-election, as discussed in further detail under Item 8.01 below.
Other Clarifying Changes
Clarifying changes were made to the following provisions in the Amended By-Laws:
•
Section 3.3 was revised to remove references to the classification of directors.
•
References to the Senior Chairman were removed from sections 2.2, 2.8, 3.3, 3.8, 3.11, 4.1, 4.2, 6.1 and 6.3.
•
Sections 2.7, 3.14, 5.1, 6.2 and 7.5 were revised to include updated references to the applicable sections of the Texas Business Organizations Code.
•
Section 5.1 was revised to (i) include arbitration proceedings among the actions, suits or proceedings for which indemnification is available and (ii) include persons acting as an administrator at the request of Cullen/Frost among those eligible for indemnification.
The foregoing description of the new by-law provisions does not purport to be complete and is qualified in its entirety by reference to the Amended By-Laws filed as Exhibit 3.2 to this Current Report on Form 8-K, which Exhibit is incorporated herein by reference. A copy of the Previous By-Laws is included as Exhibit 3.2 to the Annual Report on Form 10-K filed by Cullen/Frost on February 1, 2008 and is also incorporated herein by reference.
Item 8.01    Other Events
As noted above, on January 28, 2016, Cullen/Frost amended its Guidelines to incorporate a director resignation policy such that (i) the Guidelines provide that if an incumbent director fails to receive the vote required for re-election, such director shall promptly tender his or her resignation following the certification of the vote; (ii) the Corporate Governance and Nominating Committee shall consider such resignation irrevocable and shall recommend to the Board the action to be taken; (iii) the director who has tendered his or her resignation pursuant to this provision shall not participate in the Corporate Governance and Nominating Committee's or the Board's deliberations or decision with respect to the tendered resignation; and (iv) the Board will act on the Corporate Governance and Nominating Committee's recommendation within 90 days following the certification of the vote.
The amended Guidelines also provide that the Board intends to promptly disclose its decision whether to accept a director's resignation and an explanation of the factors it considered in making its decision, including by means of a Current Report on Form 8-K furnished or filed with the Securities and Exchange Commission.
A copy of the Guidelines will be made available on Cullen/Frost's website at
