[1] During the second quarter of 2012, the Company recognized a non-cash goodwill impairment charge of $9.7 million to adjust the carrying value of the orthopedic business to its estimated fair value.

[2] The $2.3 million pre-tax gain on disposition in 2012 reflects the gain recognized on the working capital adjustment in the second quarter related to the sale of the cargo systems and cargo container businesses.

[3] The provision for income taxes for the three and six months ended July 1, 2012 was impacted favorably by the realization of a tax benefit on impairment of goodwill. The provision for income taxes for the three months ended June 26, 2011 was impacted favorably by the realization of net tax benefits resulting from the resolution (including the expiration of statutes of limitation) of U.S. federal, state, and foreign tax matters relating to prior years. In addition, the provision for income taxes for the six months ended June 26, 2011 was further impacted favorably because taxes on the sale of the marine business were incurred at a rate that was significantly lower than the statutory tax rate.
