Supplemental Cash Flow Disclosure

In 2011 and 2010, we allocated $97,000 and $185,000, respectively, of noncontrolling interests to additional paid-in capital with regard to the exchange of 15,947 and 10,235 Units, respectively, for common stock.

Depreciation and amortization expense is comprised of the following (in thousands):

	Year Ended December 31,
	2011		2010		2009
Depreciation and amortization from continuing operations	$	133,119	$	133,393	$	131,555
Depreciation and amortization from discontinued operations	5,773		14,270		18,533
Total depreciation and amortization expense	$	138,892	$	147,663	$	150,088

In the fourth quarter of 2011, we assumed a $64.9 million loan related to our Knickerbocker development project, which is fully secured by restricted cash. We recorded this transaction as an increase in debt and a corresponding increase in restricted cash. By assuming the existing loan when we purchased the building, we were not required to pay any local mortgage recording tax. When that loan is transferred to a new lender and made part of our construction loan, we expect to only pay such tax to the extent of the incremental principal amount of the construction loan.

For the year ended December 31, 2011, our repayment of borrowings consisted of debt retirement of $983.4 million, payments on our line of credit of $145 million and normal recurring principal payments of $7.4 million.

For the year ended December 31, 2010, our repayment of borrowings consisted of debt retirement of $387.8 million and normal recurring principal payments of $13.2 million.
