Property investments; ?
Recurring leasing/capital costs; ?
Dividends and distributions to shareholders and unitholders; ?

Dividends and Distributions In order to qualify as a REIT for federal income tax purposes, we must currently distribute at least 90% of our taxable income to shareholders.
We paid dividends per share of $1.91, $1.89 and $1.87 for the years ended December 31, 2007, 2006 and 2005, respectively.
We also paid a one-time special dividend of $1.05 per share in 2005 as a result of the significant gain realized from an industrial portfolio sale.
We expect to continue to distribute taxable earnings to meet the requirements to maintain our REIT status.
