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

The computation of our basic and diluted earnings per share and unit was as follows (in thousands, except per share and unit amounts):

The exchangeable limited partnership units include the units as discussed in Note 7. Earnings allocated to the exchangeable OP units not held by the Parent have been included in the numerator and exchangeable common units have been included in the denominator for the purpose of computing diluted earnings per share for all periods as the per share and unit amount is the same.
