[1] The assumed conversion of outstanding preferred stock was anti-dilutive in all periods presented, and therefore no adjustment was required to determine diluted net income from continuing operations or average shares-diluted.

[2] Options to purchase 2.3 million and 3.3 million shares of common stock were outstanding during the first three months of 2013 and 2012, respectively, but were not included in the computation of diluted income per common share because the impact would have been anti-dilutive as the option price was higher than the average market price during those periods.
