Fair Value Measurements

(a) Disclosure of Fair Value of Financial Instruments

All financial instruments of the Company are reflected in the accompanying Consolidated Balance Sheets at amounts which, in management's estimation, reasonably approximate their fair values, except for the following:



	September 30, 2017			December 31, 2016
(in thousands)	Carrying Amount		Fair Value	Carrying Amount		Fair Value
Financial assets:
Notes receivable	$	13,984	13,869	$	10,481	10,380
Financial liabilities:
Notes payable	$	2,943,986	3,027,557	$	1,363,925	1,435,000
Unsecured credit facilities	$	578,144	580,000	$	278,495	279,700

The above fair values represent management's estimate of the amounts that would be received from selling those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants as of September 30, 2017 and December 31, 2016, respectively. These fair value measurements maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the fair value measurement reflects the Company's own judgments about the assumptions that market participants would use in pricing the asset or liability.

The Company develops its judgments based on the best information available at the measurement date, including expected cash flows, appropriate risk-adjusted discount rates, and available observable and unobservable inputs. Service providers involved in fair value measurements are evaluated for competency and qualifications on an ongoing basis. As considerable judgment is often necessary to estimate the fair value of these financial instruments, the fair values presented above are not necessarily indicative of amounts that will be realized upon disposition of the financial instruments.

The following methods and assumptions were used to estimate the fair value of these financial instruments:

Notes Receivable

The fair value of the Company's Notes receivable is estimated by calculating the present value of future contractual cash flows discounted at interest rates available for notes of the same terms and maturities, adjusted for counter-party specific credit risk. The fair value of Notes receivable was determined primarily using Level 3 inputs of the fair value hierarchy, which considered counter-party credit risk and collateral risk of the underlying property securing the note receivable.

Notes Payable

The fair value of the Company's unsecured debt is estimated based on the quoted market prices for the same or similar issues or on the current rates offered to the Company for debt of the same remaining maturities. The fair value of the unsecured debt was determined using Level 2 inputs of the fair value hierarchy.

The fair value of the Company's mortgage notes payable is estimated by discounting future cash flows of each instrument at rates that reflect the current market rates available to the Company for debt of the same terms and maturities. Fixed rate loans assumed in connection with real estate acquisitions are recorded in the accompanying consolidated financial statements at fair value at the time the property is acquired. The fair value of the mortgage notes payable was determined using Level 2 inputs of the fair value hierarchy.

Unsecured Credit Facilities

The fair value of the Company's Unsecured credit facilities is estimated based on the interest rates currently offered to the Company by financial institutions. The fair value of the credit facilities was determined using Level 2 inputs of the fair value hierarchy.

The following interest rate ranges were used by the Company to estimate the fair value of its financial instruments:



	September 30, 2017		December 31, 2016
	Low	High	Low	High
Notes receivable	3.5%	7.4%	7.2%	7.2%
Notes payable	3.1%	3.7%	2.9%	3.9%
Unsecured credit facilities	1.7%	2.2%	1.5%	1.6%

(b) Fair Value Measurements

The following financial instruments are measured at fair value on a recurring basis:

Trading Securities Held in Trust

The Company has investments in marketable securities, which are assets of the non-qualified deferred compensation plan ("NQDCP"), that are classified as trading securities and included within Other assets on the accompanying Consolidated Balance Sheets. The fair value of the trading securities held in trust was determined using quoted prices in active markets, which are considered Level 1 inputs of the fair value hierarchy. Changes in the value of trading securities are recorded within net investment (income) loss from deferred compensation plan in the accompanying Consolidated Statements of Operations.

Available-for-Sale Securities

Available-for-sale securities consist of investments in certificates of deposit and corporate bonds, and are recorded at fair value using matrix pricing methods to estimate fair value, which are considered Level 2 inputs of the fair value hierarchy. Unrealized gains or losses on these securities are recognized through Other comprehensive income.

Interest Rate Derivatives

The fair value of the Company's interest rate derivatives is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements.

Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and its counterparties. The Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its interest rate swaps. As a result, the Company determined that its interest rate swaps valuation in its entirety is classified in Level 2 of the fair value hierarchy.

The following tables present the placement in the fair value hierarchy of assets and liabilities that are measured at fair value on a recurring basis:
