The Company has categorized its financial assets and financial liabilities that are recorded at fair value into a hierarchy based on whether the inputs to valuation techniques are observable or unobservable. The fair value hierarchy contains three levels of inputs that may be used to measure fair value as follows:

Level 2 - Inputs, other than those included in Level 1, represent observable measurements for similar instruments in active markets, or identical or similar instruments in markets that are not active, and observable measurements or market data for instruments with substantially the full term of the asset or liability.

Level 3 - Inputs represent unobservable measurements, supported by little, if any, market activity, and require considerable assumptions that are significant to the fair value of the asset or liability. Market valuations must often be determined using discounted cash flow methodologies, pricing models or similar techniques based on the Company's assumptions and best judgment.

Intangible lease assets and other assets in the consolidated balance sheets include marketable securities consisting of corporate equity securities, mortgage/asset-backed securities, mutual funds and bonds that are classified as available for sale. Net unrealized gains and losses on available-for-sale securities that are deemed to be temporary in nature are recorded as a component of accumulated other comprehensive income in redeemable noncontrolling interests, shareholders' equity and noncontrolling interests. If a decline in the value of an investment is deemed to be other than temporary, the investment is written down to fair value and an impairment loss is recognized in the current period to the extent of the decline in value. During the three and six month periods ended June 30, 2011 and 2010, the Company did not record any write-downs related to other-than-temporary impairments. During the six months ended June 30, 2011, the Company recognized realized losses $22 related to sales of marketable securities. The fair value of the Company's available-for-sale securities is based on quoted market prices and, thus, is classified under Level 1. The following is a summary of the equity securities held by the Company as of June 30, 2011 and December 31, 2010:

			Gross Unrealized
	Adjusted Cost		Gains		Losses			Fair Value

The Company holds a secured convertible promissory note from Jinsheng Group ("Jinsheng"), in which the Company also holds a cost-method investment. The secured convertible note is non-interest bearing and is secured by shares of Jinsheng. Since the secured convertible note is non-interest bearing and there is no active market for Jinsheng's debt, the Company performed an analysis on the note considering credit risk and discounting factors to determine the fair value. Due to the significant estimates and assumptions used in the valuation of the note, the Company has classified it under Level 3. The Company performed quantitative and qualitative analyses of its investment as of June 30, 2011 and determined that the current balance of the secured convertible note of $2,475 is not impaired. See Note 5 for further discussion.

The Company uses interest rate hedges to mitigate the effect of interest rate movements on its variable-rate debt. The Company had four interest rate swaps and two interest rate caps as of June 30, 2011 and one interest rate cap as of December 31, 2010 that qualify as hedging instruments and are designated as cash flow hedges. The interest rate caps are included in intangible lease assets and other assets and the interest rate swaps are reflected in accounts payable and accrued liabilities in the accompanying condensed consolidated balance sheets. The swaps and caps have predominantly met the effectiveness test criteria since inception and changes in their fair values are, thus, primarily reported in other comprehensive income and are reclassified into earnings in the same period or periods during which the hedged items affect earnings. The fair values of the Company's interest rate hedges, classified under Level 2, are determined using a proprietary model which is based on prevailing market data for contracts with matching durations, current and anticipated London Interbank Offered Rate ("LIBOR") information, consideration of the Company's credit standing, credit risk of the counterparties and reasonable estimates about relevant future market conditions. See Note 6 for further information regarding the Company's interest rate hedging activity.

The carrying values of cash and cash equivalents, receivables, accounts payable and accrued liabilities are reasonable estimates of their fair values because of the short-term nature of these financial instruments. Based on the interest rates for similar financial instruments, the carrying value of mortgage notes receivable is a reasonable estimate of fair value. The estimated fair value of mortgage and other indebtedness was $5,619,338 and $5,709,860 at June 30, 2011 and December 31, 2010, respectively. The estimated fair value was calculated by discounting future cash flows for the notes payable using estimated market rates at which similar loans would be made currently.

The Company recorded a non-cash loss on impairment of real estate of $4,457 during the second quarter of 2011 related to the second phase of Settlers Ridge in Robinson Township, PA, which is currently under construction. The development property is expected to be sold upon completion and stabilization and the loss was recorded to write down the book value of the property to its estimated fair value. The fair value was estimated using the expected sales price and the projected book value of the completed property.
