Income taxes for both the third quarter and the nine months ended September 30, 2012 and 2011 include the reversal of uncertain tax positions of $7.8 million and $14.0 million, respectively. Income taxes for the nine months ended September 30, 2011 includes the impact of a $10.5 million charge resulting from the enactment on May 25, 2011 of the Michigan Corporate Income Tax which eliminated certain future tax deductions.

The amount of our uncertain tax positions whose statute of limitations are expected to expire during the next twelve months and which would affect our effective tax rate is $6.3 million as of September 30, 2012.
