[1] Assumed conversion of convertible notes at the beginning of the period has an antidilutive effect on earnings per share. All outstanding restricted shares and shares applicable to stock options and restricted stock units are excluded because their inclusion would have an antidilutive effect on the loss per share.

[2] For the three months ended June 30, 2013 and 2012, the warrants were not assumed exercised because the exercise price was more than the average price for the periods presented.
