Item 5.03 Amendments to Articles of Incorporation or By-Laws
Effective July 31, 2015, the Board of Directors (the "Board") of GATX Corporation (the "Company") amended and restated the Company's Amended and Restated By-Laws (the "By-Laws"), effective immediately.  The By-Laws include the following amendments:
Article I, Section 3 of the By-Laws has been amended to clarify that business conducted at special meetings is limited to the purposes stated in the notice provided.  Additionally, the amendments clarify that the chairman of a special meeting may postpone, reschedule or cancel any previously scheduled special meeting.
Article I, Section 5 of the By-Laws has been amended to clarify that the chairman of the meeting may adjourn the meeting from time to time, whether or not a quorum is present at such meeting.
Article I, Section 11 of the By-Laws has been amended to update the advance notice and related procedural and disclosure requirements by which a shareholder may propose business and nominations in connection with an annual or special meeting of shareholders (the "Proposing Person").  The amendments require that the Proposing Person provide information, including the Proposing Person's ownership of securities in the Company (including ownership of derivative securities) and certain material legal proceedings, relationships, contracts and agreements.  Additionally, the By-Laws require the Proposing Person to provide information regarding any candidate whom the Proposing Person proposes to nominate for election as a director, including all information with respect to such nominee that would be required to be set forth in a shareholder's notice if such nominee were a Proposing Person.  The amendments also require the Proposing Person to provide information regarding any business other than nominations for elections.  In addition, the Proposing Person must update or supplement its notice, if necessary, prior to the shareholders meeting, and the Proposing Person (or a qualified representative) must appear at such meeting in order for such candidate to be elected or such business to be conducted.
Article I, Section 12 has been added to the By-Laws to provide additional requirements for the valid nomination and election of a candidate for director.  The new section requires that a candidate provide (i) certain background information and (ii) representations regarding disclosure of voting and compensation arrangements and compliance with the Company's policies and guidelines.  Additionally, a candidate for director must update or supplement the information provided, if necessary, prior to the stockholder meeting.
The By-Laws also include certain technical, conforming, modernizing and clarifying changes.  The foregoing description is qualified in its entirety by the By-Laws which are attached hereto as Exhibit 3.1 and incorporated herein by reference.
