Item 5.02     Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

(e) On January 5, 2013, the Board of Directors (the “Board”) of International Game Technology (the “Company”) approved certain amendments, as described below, to the International Game Technology 2002 Stock Incentive Plan (the “SIP”), subject to approval by the Company’s stockholders of such amendments at the 2013 Annual Meeting of Stockholders (the “2013 Annual Meeting”). The Company’s stockholders approved the amendments at the 2013 Annual Meeting on March 5, 2013.

The SIP was scheduled to expire on December 17, 2013. The amendments extend the Company’s ability to grant new awards under the SIP until December 31, 2022. The amendments also extend the Company’s ability to grant certain performance-based awards, designed to satisfy the requirements for deductibility of compensation under Section 162(m) of the U.S. Internal Revenue Code, through the first annual meeting of the Company’s stockholders that occurs in 2018. This expiration time is earlier than the proposed expiration date of the SIP as described above and is required under applicable tax rules.

Except as amended as described above, the other terms and conditions of the SIP will continue in effect. A more complete description of the terms of the amended SIP can be found in “Proposal 2—Approval of an Amendment to the International Game Technology 2002 Stock Incentive Plan” in the Company’s definitive proxy statement dated January 23, 2013 and filed with the Securities and Exchange Commission on January 23, 2013, which description is incorporated by reference herein.
