14. Fair Value of Instruments

We disclose fair value information about all financial instruments, whether or not recognized in the condensed consolidated balance sheets, for which it is practicable to estimate fair value. Current accounting guidance requires the Company to disclose fair value information about all financial instruments, whether or not recognized in the balance sheets, for which it is practicable to estimate fair value.

The Company’s disclosures of estimated fair value of financial instruments at March 31, 2013 and December 31, 2012 were determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair value. The use of different market assumptions or estimation methods may have a material effect on the estimated fair value amounts.

The carrying amounts for cash and cash equivalents, restricted cash, accounts and other receivables, accounts payable and other accrued liabilities, accrued dividends and distributions, security deposits and prepaid rents approximate fair value because of the short-term nature of these instruments. As described in note 13, the interest rate swaps are recorded at fair value.

We calculate the fair value of our mortgage loans, unsecured term loan, unsecured senior notes and exchangeable senior debentures based on currently available market rates assuming the loans are outstanding through maturity and considering the collateral and other loan terms. In determining the current market rate for fixed rate debt, a market spread is added to the quoted yields on federal government treasury securities with similar maturity dates to debt. The carrying value of our global revolving credit facility approximates fair value, due to the variability of interest rates.

As of March 31, 2013 and December 31, 2012, the aggregate estimated fair value and carrying value of our global revolving credit facility, unsecured term loan, unsecured senior notes, exchangeable senior debentures and mortgage loans were as follows (in thousands):



		As of March 31, 2013		As of December 31, 2012
	Categorization under the fair value hierarchy	Estimated Fair Value	Carrying Value	Estimated Fair Value	Carrying Value

		$ 5,104,846	$ 4,682,124	$ 4,680,357	$ 4,278,565


(1)	The carrying value of our global revolving credit facility approximates estimated fair value, due to the variability of interest rates and the stability of our credit rating.
(2)	The carrying value of our unsecured term loan approximates estimated fair value, due to the variability of interest rates and the stability of our credit rating.


(3)	Valuations for our unsecured senior notes, mortgage loans and other secured loan are determined based on the expected future payments discounted at risk-adjusted rates. The 2015 Notes, 2020 Notes, 2021 Notes, 2022 Notes and 2025 Notes and exchangeable senior debentures are valued based on quoted market prices.


(4)	The carrying value of the 2015 Notes, 2020 Notes, 2021 Notes, 2022 Notes and 2025 Notes are net of discount of $15,948 and $11,779 in the aggregate as of March 31, 2013 and December 31, 2012, respectively.
