For purposes of this table, “earnings” consists of income before income taxes plus fixed charges and less capitalized interest. “Fixed charges” consists of interest expense and capitalized interest. The pro forma calculation assumes that the notes were issued on, and accrued interest from, October 1, 2010 and that the net proceeds were used, on the first day of each fiscal quarter, to reduce amounts outstanding under our senior secured revolving credit facility at the end of such quarter. The calculation also assumes that such net amount outstanding under the credit facility, if any, was outstanding for the full fiscal quarter.
