INCOME TAXES
The effective tax rate on continuing operations for the three months ended March 31, 2013 was 18.4 percent compared to 22.7 percent for the same period of 2012. The 4.3 percentage point decrease was due mainly to current and prior year tax benefits recorded in the quarter due to the retroactive reinstatement of the Federal Research and Development Tax Credit and the IRC Section 954(c)(6), Look-Thru Rule for Related Controlled Foreign Corporations. Both retroactive reinstatements occurred as part of the American Taxpayer Relief Act of 2012 enacted on January 2, 2013.
