15.Fair Value Measurements

Fair Value Measurements on a Recurring Basis

To manage or hedge our exposure to interest rate risk, we follow established risk management policies and procedures, including the use of a variety of derivative financial instruments.

As of June 30, 2025 and December 31, 2024, we had various derivative financial instruments consisting of interest rate swap and cap agreements that are measured at fair value on a recurring basis. The net unrealized gain (loss) on our derivative financial instruments designated as effective hedges was ($2.0) million and $17.2 million as of June 30, 2025 and December 31, 2024 and was recorded in "Accumulated other comprehensive income (loss)" in our balance sheets, of which a portion was allocated to "Redeemable noncontrolling interests." Within the next 12 months, we expect to reclassify $2.3 million of the net unrealized gain as a decrease to interest expense.

Accounting Standards Codification 820 ("Topic 820"), Fair Value Measurement and Disclosures, defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). Topic 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels:

Level 1 — quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities;

Level 2 — observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and

Level 3 — unobservable inputs that are used when little or no market data is available.

The fair values of the derivative financial instruments are based on the estimated amounts we would receive or pay to terminate the contracts at the reporting date and are determined using interest rate pricing models and observable inputs. The derivative financial instruments are classified within Level 2 of the valuation hierarchy.

The following is a summary of assets and liabilities measured at fair value on a recurring basis:

The fair values of our derivative financial instruments were determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of the derivative financial instrument. This analysis reflected the contractual terms of the derivative, including the period to maturity, and used observable market-based inputs, including interest rate market data and implied volatilities in such interest rates. While it was determined that the majority of the inputs used to value the derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with the derivatives also utilized Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default. However, as of June 30, 2025 and December 31, 2024, the significance of the impact of the credit valuation adjustments on the overall valuation of the derivative financial instruments was assessed, and it was determined that these adjustments were not significant to the overall valuation of the derivative financial instruments. As a result, it was determined that the derivative financial instruments in their entirety should be classified in Level 2 of the fair value hierarchy. The net unrealized gains (losses) included in "Other comprehensive income (loss)" in our statements of comprehensive loss for the three and six months ended June 30, 2025 and 2024 were attributable to the net change in unrealized gains (losses) related to effective derivative financial instruments that were outstanding during those periods, none of which were reported in our statements of operations as the derivative financial instruments were documented and qualified as hedging instruments. Realized and unrealized gains (losses) related to non-designated hedges are included in "Interest expense" in our statements of operations.

Fair Value Measurements on a Nonrecurring Basis

Our real estate assets are reviewed for impairment whenever there are changes in circumstances or indicators that the carrying amount of the assets may not be recoverable. Real estate held for sale is carried at the lower of carrying amounts or estimated fair value less disposal costs.

During the six months ended June 30, 2025, this assessment resulted in the impairment of The Batley and a development parcel, which had an estimated fair value totaling $162.0 million based on a market approach and were classified as Level 2 in the fair value hierarchy. The impairment loss totaled $40.3 million, which was included in "Impairment loss" in our statement of operations for the six months ended June 30, 2025. The Batley was classified as held for sale as of June 30, 2025 and sold in July 2025.

Financial Assets and Liabilities Not Measured at Fair Value

As of June 30, 2025 and December 31, 2024, all financial assets and liabilities were reflected in our balance sheets at amounts which, in our estimation, reasonably approximated their fair values, except for the following:

​

The fair values of the mortgage loans, revolving credit facility and term loans were determined using Level 2 inputs of the fair value hierarchy. The fair value of our mortgage loans is estimated by discounting the future contractual cash flows of these instruments using current risk-adjusted rates available to borrowers with similar credit profiles based on market sources. The fair value of our revolving credit facility and term loans is calculated based on the net present value of payments over the term of the facilities using estimated market rates for similar notes and remaining terms.
