Fair Value Measurements

In accordance with ASC 820, Fair Value Measurement and Disclosures, the Company defines fair value based on the price that would be received upon sale of an asset or the exit price that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value. The fair value hierarchy consists of three broad levels, which are described below:


•	Level 1 – Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.


•	Level 2 – Observable inputs, other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.


•	Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

The Company has estimated the fair value of its financial and non-financial instruments using available market information and valuation methodologies the Company believes to be appropriate for these purposes. Considerable judgment and a high degree of subjectivity are involved in developing these estimates and, accordingly, they are not necessarily indicative of amounts that would be realized upon disposition.

Recurring Measurements

For assets and liabilities measured at fair value on a recurring basis, quantitative disclosure of the fair value for each major category of assets and liabilities is presented below:



	Fair Value Measurements at March 31, 2018
Assets	Level 1		Level 2		Level 3
Marketable equity securities	$	4,416	$	—	$	—
Real estate related bonds	—		321		—
Derivative interest rate swaps	—		2,337		—
Total assets	$	4,416	$	2,658	$	—



	Fair Value Measurements at December 31, 2017
Assets	Level 1		Level 2		Level 3
Available-for-sale marketable securities	$	4,431	$	—	$	—
Real estate related bonds	—		327		—
Derivative interest rate swaps	—		1,670		—
Total assets	$	4,431	$	1,997	$	—

Level 1

At March 31, 2018 and December 31, 2017, the fair value of the marketable equity securities has been determined based upon quoted market prices. In accordance with the adoption of ASU No. 2016-01 on January 1, 2018, changes in the fair value of the Company's investment in marketable equity securities are now recorded as a component of net income through realized and unrealized investment (loss) income, net on the condensed consolidated statements of operations and comprehensive income (loss). Prior to the adoption of ASU No. 2016-01, changes in the fair value, representing unrealized holding gains and losses on available-for-sale securities, of the Company's investments in marketable securities were reported as a separate component of comprehensive income (loss) until realized.

Level 2

To calculate the fair value of the real estate related bonds and the derivative interest rate instruments, the Company primarily uses quoted prices for similar securities and contracts. For the real estate related bonds, the Company reviews price histories for similar market transactions. For the derivative interest rate instruments, the Company uses inputs based on data that is observed in the forward yield curve which is widely observable in the marketplace. The Company also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements which utilizes Level 3 inputs, such as estimates of current credit spreads. However, as of March 31, 2018 and December 31, 2017, the Company determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. As of March 31, 2018 and December 31, 2017, the Company had outstanding interest rate swap agreements with an aggregate notional value of $150,000.

Level 3

At March 31, 2018 and December 31, 2017, the Company had no Level 3 recurring fair value measurements.

Nonrecurring Measurements

During the three months ended March 31, 2018, the Company identified one retail property that had a reduction in the expected holding period. The Company's estimated fair value was based on an executed purchase contract. The Company recorded a provision for asset impairment of $797 on that retail property.

During the three months ended March 31, 2017, the Company identified certain retail properties that may have reductions in their expected holding periods and reviewed the probability of these retail properties' disposition. The Company's estimated fair values for purposes of the impairment analyses were based on broker opinions of value and letters of intent. As a result, during the three months ended March 31, 2017, the Company recorded a provision for asset impairment of $16,440 on three retail assets.

The following table summarizes activity for the Company’s assets measured at fair value on a nonrecurring basis and the related impairment charges to reflect the investments at their fair values for the three months ended March 31, 2018 and 2017, as described above.



	For the three months ended March 31,
	2018				2017
	Level 3		Impairment Losses		Level 3		Impairment Losses
Investment properties	$	31,000	$	797	$	36,676	$	16,440

Financial Instruments Not Measured at Fair Value

The table below represents the fair value of financial instruments presented at carrying values in the Company's condensed consolidated financial statements as of March 31, 2018 and December 31, 2017.



	March 31, 2018				December 31, 2017
	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value
Mortgages payable	$	332,630	$	331,909	$	370,804	$	372,962
Line of credit and term loan	$	300,000	$	299,791	$	300,000	$	299,770

The Company estimated the fair value of its mortgages payable using a weighted average effective market interest rate of 4.44% as of March 31, 2018 compared to 4.20% as of December 31, 2017.

The fair value estimate of the line of credit and term loan approximates the carrying value due to limited market volatility in pricing. The assumptions reflect the terms currently available on similar borrowing terms to borrowers with credit profiles similar to the Company's. As a result, the Company used a weighted average interest rate of 3.88% as of March 31, 2018 compared to 3.48% as of December 31, 2017 to estimate the fair value of its line of credit and term loan. The Company has determined that its debt instrument valuations are classified in Level 2 of the fair value hierarchy.
