Goodwill [Abstract]
Goodwill	Note 9 – Goodwill Goodwill, which represents the cost of an acquired company in excess of the fair value of the net assets at the acquisition date, has been recorded in connection with the acquisition of W.E.T. and is subject to annual impairment testing or when events or changes in circumstances indicate the carrying amount may not be recoverable. We evaluate the recoverability of goodwill by comparing the carrying value of the reporting units that have allocated goodwill to their fair value. Fair value is determined using discounted cash flows supplemented by market-based assessments of fair value. Impairment is measured as the difference between the resulting implied fair value of goodwill and its recorded carrying value. The determination of fair value is significantly impacted by unobservable input assumptions related to current and future economic conditions and our strategic plans within each geographic operating segment. As of June 30, 2012, no impairment of goodwill from the acquisition of W.E.T. had occurred.
