Earnings Per Share [Abstract]  
Earnings per Share of Common Stock Earnings per Share of Common StockBoth the net income or loss attributable to the non-controlling OP units and the non-controlling limited partners’ outstanding OP units have been excluded from the basic earnings per share and the diluted earnings per share calculations attributable to common stockholders. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are excluded from net income available to common shareholders in the computation of earnings per share pursuant to the two-class method. Certain share based awards are included in the diluted share count to the extent they are dilutive as discussed in Note 2. To the extent our convertible notes are dilutive under the if-converted method, we add back the interest expense to the numerator and include the weighted average shares of potential common stock over the period issuable upon conversion of the note in the denominator in calculating dilutive EPS as described in Note 2.
The computation of basic and diluted earnings per common share of common stock is as follows:
