(1)	The increase in goodwill for the Electronic Systems segment is due to the acquisition of ComHouse. See Note 4 for further discussion regarding this acquisition.
(2)	The increase in goodwill presented in each of the segments was due to the weakening of the U.S. dollar against the Euro, Canadian dollar, and British pound during the first half ended July 1, 2011.
(3)	As a result of re-alignments of business units in the Company’s management and organizational structure as discussed in Note 2, goodwill was reclassified on a relative fair value basis among the C3ISR, Government Services and Electronic Systems segments during the first half ended July 1, 2011.
