The Plan is a non-qualified contributory plan. In addition to the Plan, Cullen/Frost maintains the 401(k) Stock Purchase Plan for Employees of Cullen/Frost Bankers, Inc. and Its Affiliates (the &#x201c;401(k) Plan&#x201d;). The Plan covers certain employees who have been deemed eligible for participation. The Plan is intended to provide current compensation that is reasonably comparable to other benefits the participant would be able to receive during a relevant plan year under the 401(k) Plan if it were not for limitations imposed by certain sections of the Internal Revenue Code (the &#x201c;Code&#x201d;).&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-align:justify;text-indent:9pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Contributions&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;. For each plan year, each active participant is eligible to contribute an amount equal to 7% of their compensation in excess of the maximum annual compensation limit in effect under Code section 401(a)(17)(A) for the plan year. Further, each participant who also participates in the 401(k) Plan will be assumed to have made pre-tax deferrals equal to the Code section 402(g) limit in effect for that plan year. Cullen/Frost's administrative committee determines at such times as the Code limitations are applied under the 401(k) Plan. The Plan is not designed to provide deferred compensation and is intended to be exempt from Section&#160;409A of the Code.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-align:justify;text-indent:9pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;For each plan year, Cullen/Frost makes contributions equal to 100% of each participant&#x2019;s after-tax contributions to the Plan for the respective plan year.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-align:justify;text-indent:9pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Vesting&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;.
