¹ Pursuant to the guidance in the Income Taxes Topic of the FASB ASC, interest related to unrecognized tax benefits recorded was approximately $15 million and $11 million for the six months ended June 30, 2010 and 2009, respectively. The ratio of earnings to fixed charges would have been 7.98 and 7.05 for the six months ended June 30, 2010 and 2009, respectively, if such interest were excluded from the calculation.

² Reasonable approximation of the interest factor.
