(1)

The Preferred Securities are anti-dilutive for each of the three and nine months ended September 30, 2011 and 2010, and therefore have been excluded from diluted earnings per share. Had the Preferred Securities been included in the diluted earnings per share calculation, net income for each of the three-month periods ended September 30, 2011 and 2010 would be increased by $3.5 million and net income for each of the nine-month periods ended September 30, 2011 and 2010 would be increased by $10.5 million. Weighted-average shares outstanding would be increased by 8.3 million shares for all periods presented.


(2)	Share-based payment awards classified as participating securities are anti-dilutive for the three months ended September 30, 2011 and therefore have been excluded from basic and diluted earnings per share calculations. Had these securities been included, the weighted-average shares outstanding would be increased by 3.3 million for the three months ended September 30, 2011.

(3)

Dilutive securities include “in the money” options, non-participating restricted stock units and performance stock units. The weighted-average shares outstanding exclude the effect of approximately 19.3 million stock options and other securities and 12.2 million stock options for the three months ended September 30, 2011 and 2010, respectively, and 12.1 million and 12.6 million stock options for the nine months ended September 30, 2011 and 2010, respectively, because such securities were anti-dilutive.

(4)

The Convertible Notes were dilutive to the extent the average price during the period was greater than $8.61, the conversion price of the Convertible Notes, and the Convertible Notes are only dilutive for the “in the money” portion of the Convertible Notes that could be settled with the Company’s stock. The Convertible Notes were dilutive for the three and nine month periods ended September 30, 2011 and 2010, as the average price of the Company’s common stock during these periods was greater than $8.61. As disclosed in Footnote 6 of the Notes to Condensed Consolidated Financial Statements, substantially all of the remaining outstanding principal amount of the Convertible Notes was extinguished in March 2011, and as such, dilution for the three and nine months ended September 30, 2011 takes into consideration the period of time the Convertible Notes were outstanding. The Convertible Notes will not meaningfully impact diluted average shares outstanding in subsequent periods because the maximum amount of shares required to settle the “in the money” portion of the $0.1 million principal amount of the Convertible Notes outstanding as of September 30, 2011 is not material.


(5)	The warrant transaction was settled during September 2010 and as such the warrants did not impact diluted average shares outstanding in periods subsequent thereto. The warrants were dilutive for the three and nine months ended September 30, 2010, as the average price of the Company’s common stock during those periods was greater than $11.59, the exercise price of the warrants.
