Earnings (Loss) Per Common Share/Unit [Abstract]  
Earnings (Loss) Per Common Share/Unit
13.   Earnings (Loss) Per Common Share /Unit

We determine basic earnings per share/unit based on the weighted average number of shares of common stock/units outstanding during the period. We compute diluted earnings per share/unit based on the weighted average number of shares outstanding combined with the incremental weighted average effect from all outstanding potentially dilutive instruments.

 

The following table sets forth the computation of our basic and diluted earnings per share/unit (in thousands, except per share/unit amounts):

(1) In periods with a net loss, the inclusion of any incremental shares/units is anti-dilutive and, therefore, both basic and diluted shares/units are the same.
(2) As a result of the Merger, the historical shares of ProLogis were adjusted by the Merger exchange ratio of 0.4464 for all periods presented. As a result, the per share/unit calculations and shares/units outstanding were also adjusted.
(3) Total weighted average potentially dilutive share awards outstanding (in thousands) were 10,132 and 3,457 for the three months ended March 31, 2012 and 2011, respectively.
