[1] The 7% Exchangeable Senior Subordinated Notes due 2014 (the “Exchangeable Notes”) were fully converted into shares of our common stock as of December 1, 2014. During the year ended December 31, 2013, the common stock reserved for conversion in connection with the Exchangeable Notes were considered to be anti-dilutive in our calculation of diluted net income per share.
[2] The sum of quarterly net income per share applicable to common stockholders (diluted) does not necessarily agree to the net income per share for the year due to the timing of common stock issuances
