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

(e) On May 3, 2010, the Personnel and Compensation Committee (the “Committee”) of the Board of Directors of Alliant Techsystems Inc. (“ATK”) approved an amendment and restatement of the Alliant Techsystems Inc. Income Security Plan (the “Plan”). In addition to making certain administrative changes, the Committee revised the Plan by

· placing a cap on the compensation and benefits that may be paid under the Plan in order to avoid the imposition of any excise tax and the corresponding gross-up on such excise tax by ATK, and

· adding a modified “sunset” provision applicable to ATK’s chief executive officer, chief financial officer, chief operating officer (if there is someone in that position) and general counsel under which, on each of the fifth through ninth anniversaries of the date of service in that position, the amount payable would be reduced by an increment of 0.2, for a total decrease from three times compensation to two times compensation over that five-year period.

This description is qualified in its entirety by reference to the full text of the Plan amendment, which is attached to this report as Exhibit 10.1 and is hereby incorporated by reference.
