[1] The provision for income taxes for the nine months ended September 25, 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 and by the tax on the gain from sale of the marine business being incurred at significantly lower than statutory effective tax rates.
