[1] Reflects a reduction due to our 4 percent Convertible Senior Notes being convertible at June 30, 2011 (an amount equal to the unamortized portion of the original issue discount was reclassified out of stockholders' deficit and is reflected as "temporary equity" in our condensed consolidated balance sheets as of June 30, 2011), and a reduction reflecting the excess of the cash transferred upon conversion of a portion of the 4 percent Convertible Senior Notes during the second quarter of 2011 over the principal amount of the converted notes, net of cash received from the option counterparties to our convertible note hedges upon the conversion. See note 6 to our condensed consolidated financial statements for additional detail.
