PART II  NOTE 15 Equity NOTE 15 Equity The following is a summary of our capital stock activity over the past three years: At December 31, 2010, 5.7 million shares of FMC common stock were reserved for stock options and awards. Accumulated other comprehensive gain (loss) consisted of the following: On January 20, 2011, we paid dividends aggregating $9.0 million to our  shareholders of record as of December 31, 2010. This amount is included  in “Accrued and other liabilities” on the consolidated balance sheets as  of December 31, 2010. For the years ended December 31, 2010, 2009  and 2008, we paid $36.4 million, $36.3 million and $34.4 million in  dividends, respectively. On October 24, 2008, the Board of Directors authorized the repurchase  of up to $250 million of our common stock. At December 31, 2010,  $54.8 million remained unused of the 2008 authorization. On  February 18, 2011, the Board authorized the repurchase of up to  an additional $250 million of our common stock for a total of  $304.8 million. The repurchase program does not include a specifi c  timetable or price targets and may be suspended or terminated at any time.  Shares may be purchased through open market or privately negotiated  transactions at the discretion of management based on its evaluation  of market conditions and other factors. During the twelve months  ended December 31, 2010, we repurchased 1,874,519 shares under  the publicly announced repurchase program for $135.0 million. We  also reacquire shares from time to time from employees in connection  with the vesting, exercise and forfeiture of awards under our equity  compensation plans. Earnings (loss) per common share (“EPS”) is computed by dividing  net income (loss) by the weighted average number of common shares  outstanding during the period on a basic and diluted basis. Our potentially dilutive securities include potential common shares related  to our stock options, restricted stock and restricted stock units. Diluted  earnings per share (“Diluted EPS”) considers the impact of potentially  dilutive securities except in periods in which there is a loss because the  inclusion of the potential common shares would have an antidilutive  effect. Diluted EPS excludes the impact of potential common shares  related to our stock options in periods in which the option exercise  price is greater than the average market price of our common stock  for the period. For the years ended December 31, 2010 and 2008,  there were no potential common shares excluded from Diluted EPS.  For the year ended December 31, 2009 there were 278,173 potential  common shares excluded from Diluted EPS. Our non-vested restricted stock awards contain rights to receive non- forfeitable dividends, and thus, are participating securities requiring the  two-class method of computing EPS. The two-class method determines  EPS by dividing the sum of distributed earnings to common stockholders  and undistributed earnings allocated to common stockholders by the  weighted average number of shares of common stock outstanding for  the period. In calculating the two-class method, undistributed earnings  are allocated to both common shares and participating securities based  on the weighted average shares outstanding during the period. 62 FMC CORPORATION    2010 Form 10K NOTE 16 Earnings Per Share (Number of Shares in Th  ousands) Common Stock Treasury Stock December 31, 2007 92,992 17,862 Stock options and awards — (920) Repurchases of common stock, net — 3,540 December 31, 2008 92,992 20,482 Stock options and awards — (733) Repurchases of common stock, net — 724 December 31, 2009 92,992 20,473 Stock options and awards — (884) Repurchases of common stock, net — 1,917 DECEMBER 31, 2010 92,992 21,506 (in Millions) December 31, 2010 2009 Deferred (loss) gain on derivative contracts $(3.5) $(0.1) Pension and other postretirement liability adjustment (293.3) (289.8) Foreign currency translation adjustments (14.9) 10.7 ACCUMULATED OTHER COMPREHENSIVE GAIN (LOSS) $(311.7) $(279.2)
