Ratio of earnings to fixed charges (2)		1.9		3.3			2.0			—			2.6		2.1

(1)	Represents one-third of total rent expense which we believe is a reasonable estimate of the interest component of rent expense.
(2)	The ratio of earnings to fixed charges was less than 1:1 for 2008. In order to achieve a ratio of earnings to fixed charges of 1:1, we would have had to generate an additional $425.7 million of earnings in 2008.
