General Dynamics Corp. provided earnings guidance for the year 2012. For 2012, the company expects net interest expense between $155 million and $160 million, reflecting the full year impact of the $1.5 billion of fixed rate notes issued in 2011. For 2012, the company expects an effective tax rate of approximately 32%, rising slightly over the 2011 rate, but due in large measure to the current lack of an extension at the R&D tax credit and the provisions of the tax code. Total earnings per share from continuing operations in a range between $7.10 and $7.20.
