[1] | 1We converted all of our Series B Preferred Stock into common stock in October 2013. See Note 3 for further information. For purposes of calculating diluted earnings per share for 2013, the potentially dilutive shares would have been pro-rated based on the period they were outstanding but were antidilutive.
[2] | 2 These options are outstanding at the end of the respective periods. In any period in which the exercise price is less than the average market price, these options have the potential to be dilutive, and application of the treasury stock method would reduce this amount.
