ATK to Keep Stockholder Rights Plan in Effect

MINNEAPOLIS, Aug. 5 /PRNewswire-FirstCall/ -- Alliant Techsystems
(NYSE: ATK) said its board of directors has decided to keep ATK's stockholder
rights plan in effect without any modifications. The rights plan, which was
adopted by the board in May 2002, is intended to assure that ATK stockholders
receive fair and equal treatment if efforts are made to gain control of the
company without paying all stockholders a premium value.
At the time the stockholder rights plan was approved, the board also
adopted a three-year independent director evaluation ("TIDE") policy with
respect to the plan. The TIDE policy requires the nominating and governance
committee of the board, which is composed solely of independent directors, to
determine at least once every three years whether maintenance of the plan
continues to be in the best interests of ATK and its stockholders.
After conducting a review in accordance with the TIDE policy, the
nominating and governance committee concluded that the rights plan continues
to be an important mechanism for protecting long-term stockholder value and
recommended that the board continue to maintain the plan. The board of
directors continues to believe that the rights plan is an important defense
against coercive and inadequate offers that could undermine its ability to
effectively negotiate a fair price for stockholders.
ATK is a premier aerospace and defense company with more than 17,000
employees in 21 states and $4.5 billion in revenue. News and information can
