Redeemable Noncontrolling Interest	6 Months Ended
Redeemable Noncontrolling Interest	Oct. 26, 2011
Noncontrolling Interest [Abstract]
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interest The minority partner in Coniexpress has the right, at any time, to exercise a put option to require the Company to purchase their 20% equity interest at a redemption value determinable from a specified formula based on a multiple of EBITDA (subject to a fixed minimum linked to the original acquisition date value). The Company also has a call right on this noncontrolling interest exercisable at any time and subject to the same redemption price. The put and call options cannot be separated from the noncontrolling interest and the combination of a noncontrolling interest and the redemption feature require classification of the minority partner's interest as a redeemable noncontrolling interest in the condensed consolidated balance sheet. The carrying amount of the redeemable noncontrolling interest approximates its maximum redemption value. Any subsequent change in maximum redemption value would be adjusted through retained earnings. The reduction in carrying value from April 27, 2011 to October 26, 2011 was primarily due to the impact the weakening of the Brazilian Real had on translation into U.S. dollars. We do not currently believe the exercise of the put option would materially impact our results of operations or financial condition.
