Non-GAAP Financial Disclosure

FFO is a non-GAAP measure defined by the National Association of Real Estate Investment Trusts (“NAREIT”). NAREIT defines FFO as net income or loss (as computed in accordance with GAAP) excluding: depreciation and amortization expense from real estate assets, gains or losses from sales of depreciated real estate assets and extraordinary items; however, FFO related to assets held for sale, sold or otherwise transferred and included in the results of discontinued operations are to be included. These adjustments also incorporate the pro rata share of unconsolidated subsidiaries. FFO is used by management, investors and analysts to facilitate meaningful comparisons of operating performance between periods and among our peers. Although NAREIT has published this definition of FFO, real estate companies often modify this definition as they seek to provide financial measures that meaningfully reflect their distinctive operations.

We modify the NAREIT computation of FFO to include other adjustments to GAAP net income for certain non-cash charges, where applicable, such as gains or losses from extinguishment of debt and deconsolidation of subsidiaries, amortization of intangibles, straight-line rents, impairment charges on real estate, allowances for credit losses and unrealized foreign currency exchange gains and losses. We refer to our modified definition of FFO as “Funds from Operations — as Adjusted,” or AFFO, and we employ it as one measure of our operating performance when we formulate corporate goals and evaluate the effectiveness of our strategies. We exclude these items from GAAP net income as they are not the primary drivers in our decision-making process. Our assessment of our operations is focused on long-term sustainability and not on such non-cash items, which may cause short-term fluctuations in net income but have no impact on cash flows.

We believe that AFFO and AFFO per share are useful supplemental measures for investors to consider because it will help them to better assess the sustainability of our operating performance without the potentially distorting impact of these short-term fluctuations. However, there are limits on the usefulness of AFFO to investors. For example, impairment charges and unrealized foreign currency losses that we exclude may become actual realized losses upon the ultimate disposition of the properties in the form of lower cash proceeds or other considerations. FFO or AFFO should not be considered as an alternative to net income as an indication of a company’s operating performance or to cash flow from operating activities as a measure of its liquidity, but should be used in conjunction with GAAP net income.

		Three months ended March 31,

Cash flow provided by operating activities — as reported		$	34,563			$	40,189
Adjustments:
Distributions received from equity investments in real estate in excess of equity income, net (a)			2,207				1,583
Distributions paid to noncontrolling interests, net (b)			(5,655	)			(7,295	)

Payout ratio (distributions per share/adjusted cash flow per share)			70	%			70	%
Weighted average shares outstanding			128,943,711				126,250,242

(a)		To the extent we receive distributions in excess of the equity income that we recognize, we include such amounts in our evaluation of cash flow from core operations.
(b)		Represents noncontrolling interests’ share of distributions made by ventures that we consolidate in our financial statements.
(c)		Timing differences arising from the payment of certain liabilities and the receipt of certain receivables in a period other than that in which the item is recognized in determining net income may distort the actual cash flow that our core operations generate. We adjust our GAAP cash flow provided by operating activities to record such amounts in the period in which the item was actually recognized.
(d)		During the first quarter of 2011, we made an adjustment to exclude the impact of escrow funds from Adjusted cash flow from operating activities as, more often than not, these funds represent investing and/or financing activities. The amount previously furnished for Adjusted cash flow from operating activities for the three months ended March 31, 2010 of $27.9 million has been revised in the table above to reflect this reclassification.

Non-GAAP Financial Disclosure

Adjusted cash flow from operating activities refers to our cash flow from operating activities (as computed in accordance with GAAP) adjusted, where applicable, primarily to: add cash distributions that we receive from our investments in unconsolidated real estate joint ventures in excess of our equity income; subtract cash distributions that we make to our noncontrolling partners in real estate joint ventures that we consolidate; and eliminate changes in working capital. We hold a number of interests in real estate joint ventures, and we believe that adjusting our GAAP cash flow provided by operating activities to reflect these actual cash receipts and cash payments, as well as eliminating the effect of timing differences between the payment of certain liabilities and the receipt of certain receivables in a period other than that in which the item is recognized may give investors additional information about our actual cash flow that is not incorporated in cash flow from operating activities as defined by GAAP.

We believe that adjusted cash flow from operating activities is a useful supplemental measure for assessing the cash flow generated from our core operations as it gives investors important information about our liquidity that is not provided within cash flow from operating activities as defined by GAAP, and we use this measure when evaluating distributions to shareholders. Adjusted cash flow from operating activities should not be considered as an alternative to cash provided by operating activities computed on a GAAP basis as a measure of our liquidity.
