(1)	Represents one-third of total rent expense which we believe is a reasonable estimate of the interest component of rent expense.
(2)	For the years ended December 31, 2008 and 2005, earnings were less than fixed charges by $425.7 million and $145.2 million, respectively. We recorded a goodwill impairment charge at December 31, 2008 that reduced our earnings for 2008 by $671.1 million.
