Income taxes
 
In the first quarter of 2011, the Company received favorable resolution of certain tax matters relating to the 2004 through 2006 tax years. As a result, the Company recorded an income tax benefit from continuing operations of $4.2 million. This resolution includes the effects of $2.8 million related to the reversal of unrecognized tax benefits that were previously established for the 2004 through 2006 tax years and associated interest of $600,000.

 
In the second quarter of 2011, the Company's unrecognized tax positions increased $3.6 million, excluding interest, largely due to tax positions under examination relating to the 2007 through 2009 tax years. The ultimate deductibility of these tax positions is highly certain but there is uncertainty about the timing of such deductibility. The Company anticipates the uncertainty about the timing of the deductibility will be resolved within the next 12 months.
