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:

Level 1

At September 30, 2017 and December 31, 2016, the fair value of the available-for-sale marketable equity securities have been estimated based upon quoted market prices. Unrealized gains or losses on investment are reflected in unrealized gain (loss) on investment securities in comprehensive income on the consolidated statements of operations and comprehensive income.

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 September 30, 2017 and December 31, 2016, 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 September 30, 2017 and December 31, 2016, the Company had outstanding interest rate swap agreements with an aggregate notional value of $150,000.

Level 3

At September 30, 2017 and December 31, 2016, the Company had no Level 3 recurring fair value measurements.

Nonrecurring Measurements

The following table summarizes activity for the Company’s assets measured at fair value on a nonrecurring basis. The Company recognized certain impairment charges to reflect the investments at their fair values for the three and nine months ended September 30, 2017 and 2016. The asset groups that were reflected at fair value through this evaluation are:



	For the three months ended September 30,
	2017				2016
	Level 3		Impairment Losses		Level 3		Impairment Losses
Investment properties, continuing operations	$	—	$	—	$	27,173	$	2,818

Investment properties, continuing operations

During the three and nine months ended September 30, 2017, the Company identified certain assets which may have a reduction in the expected holding period and reviewed the probability of these assets' disposition. The Company's estimated fair value relating to the investment assets' impairment analyses was based on broker opinions of value and letters of intent and 10-year discounted cash flow models, which include estimated inflows and outflows over a specific holding period and estimated net disposition proceeds at the end of the 10-year period. The cash flows consist of observable inputs such as contractual revenues and unobservable inputs such as forecasted revenues and expenses and estimated net disposition proceeds at the end of the 10-year period. These unobservable inputs are based on market conditions and the Company’s expected growth rates. As a result, during the nine months ended September 30, 2017, the Company recorded a provision for asset impairment of $16,440 in continuing operations on three multi-tenant retail assets based on broker opinions of value and letters of intent. There was no provision for asset impairment recorded for the three months ended September 30, 2017.

During the three and nine months ended September 30, 2016, the Company identified certain assets which may have a reduction in the expected holding period and reviewed the probability of these assets' disposition. The Company's estimated fair value relating to the investment assets' impairment analyses was based on purchase contracts. As a result, during the three and nine months ended September 30, 2016, the Company recorded a provision for asset impairment of $2,818 and $11,208, respectively, in continuing operations on three multi-tenant retail assets.

Investment properties, discontinued operations

In connection with the Highlands spin-off during the nine months ended September 30, 2016, as disclosed in the Company's Annual Report, the Company evaluated Highlands as a disposal group for impairment. The Company's estimated fair value relating to the disposal group's impairment analysis was based on 10-year discounted cash flow models, which include estimated inflows and outflows over a specific holding period and estimated net disposition proceeds at the end of the 10-year period. The cash flows consist of observable inputs such as contractual revenues and unobservable inputs such as forecasted revenues and expenses and estimated net disposition proceeds at the end of the 10-year period. These unobservable inputs are based on market conditions and the Company’s expected growth rates.

As of the spin date, capitalization rates ranging from 6.75% to 10.00% and discount rates ranging from 7.75% to 15.25% were utilized in the model and were based upon observable rates that the Company believed to be within a reasonable range of current market rates. As a result of this analysis, the Company recorded a provision for asset impairment related to the Highlands spin-off of $76,583 for the nine months ended September 30, 2016.

During the nine months ended September 30, 2016, the Company identified one non-core office asset which may have a reduction in the expected holding period and reviewed the probability of this asset's disposition. The Company's estimated fair value relating to this asset's impairment analysis was based on a ten-year undiscounted cash flow model. Capitalization rates ranging from 6.75% to 7.00% and discount rates ranging from 7.00% to 8.00% were utilized in the model and were based upon observable rates that the Company believed to be within a reasonable range of market rates. As a result of this analysis, the Company recorded a provision for asset impairment of $29,931 on this asset, for a total provision for asset impairment of $106,514 in discontinued operations for the nine months ended September 30, 2016. There was no provision for asset impairment recorded as part of discontinued operations for the three months ended September 30, 2016.

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 consolidated financial statements as of September 30, 2017 and December 31, 2016.



	September 30, 2017				December 31, 2016
	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value
Mortgages payable	$	370,029	$	372,418	$	434,746	$	435,513
Line of credit and term loan	$	300,000	$	299,760	$	300,000	$	299,741

The Company estimated the fair value of its mortgages payable using a weighted average effective market interest rate of 4.19% as of September 30, 2017 compared to 5.07% as of December 31, 2016.

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 3.21% as of September 30, 2017 compared to 3.15% as of December 31, 2016 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.
