(1) For purposes of computing the ratio of earnings to fixed charges, “earnings” consists of pre-tax income from continuing operations before income from equity investees plus fixed charges (excluding capitalized interest), distributed income of equity investees and amortization of capitalized interest. “Fixed charges” represents interest incurred (whether expensed or capitalized), amortization of debt expense (including discounts and premiums relating to indebtedness) and the portion of rental expense on operating leases deemed to be the equivalent of interest.

(2) Includes interest costs attributable to borrowings for inventory stored in a contango market of $8 million for the six months ended June 30, 2010 and $11 million, $21 million, $44 million, $49 million and $24 million for each of the years ended December 31, 2009, 2008, 2007, 2006, and 2005, respectively.

(3) Ratios may not recalculate due to rounding.
