Fair Value Measurements Fair Value Measurements
 
The fair value of an asset is defined as the exit price, which is the amount that would either be received when an asset is sold or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance establishes a three-tier fair value hierarchy based on the inputs used in measuring fair value. These tiers are: Level 1, for which quoted market prices for identical instruments are available in active markets, such as money market funds, equity securities, and U.S. Treasury securities; Level 2, for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument, such as certain derivative instruments including interest rate caps, interest rate swaps, and foreign currency collars; and Level 3, for securities that do not fall into Level 1 or Level 2 and for which little or no market data exists, therefore requiring us to develop our own assumptions.

Items Measured at Fair Value on a Recurring Basis

The methods and assumptions described below were used to estimate the fair value of each class of financial instrument. For significant Level 3 items, we have also provided the unobservable inputs.

Derivative Assets and Liabilities — Our derivative assets and liabilities, which are included in Other assets, net and Accounts payable, accrued expenses and other liabilities, respectively, in the consolidated financial statements, are comprised of foreign currency collars, interest rate swaps, and interest rate caps (Note 10).

The valuation of our derivative instruments is determined using a 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, as well as observable market-based inputs, including interest rate curves, spot and forward rates, and implied volatilities. We incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative instruments for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. These derivative instruments were classified as Level 2 as these instruments are custom, over-the-counter contracts with various bank counterparties that are not traded in an active market.
Equity Method Investment in CESH — We have elected to account for our investment in CESH, which is included in Equity method investments in the consolidated financial statements, at fair value by selecting the equity method fair value option available under GAAP (Note 8). We classified this investment as Level 3 because we primarily used valuation models that incorporate unobservable inputs to determine its fair value.

Investment in Shares of Lineage — Refer to Note 2 for information about the accounting treatment of our investment in 5,546,547 shares of Lineage, which is classified as Level 2 as of December 31, 2025. During the years ended December 31, 2025 and 2024, we recognized non-cash unrealized losses on our investment in shares of Lineage totaling $103.4 million and $134.0 million, respectively, due to a lower closing share price, which was recorded within Other gains and (losses) in the consolidated financial statements. We did not recognize such gains (losses) during the year ended December 31, 2023. In addition, during the years ended December 31, 2025 and 2024, we recognized dividends of $11.3 million and $7.9 million, respectively, from our investment in shares of Lineage, which was recorded within Non-operating income in the consolidated financial statements. We did not recognize such dividends during the year ended December 31, 2023. The fair value of this investment was $167.5 million and $270.9 million at December 31, 2025 and 2024, respectively, which is reflected in Other assets, net in the consolidated financial statements.

Other than the transfer of our investment in shares of Lineage from Level 3 to Level 2 noted above, we did not have any transfers into or out of Level 1, Level 2, and Level 3 category of measurements during either the years ended December 31, 2025 or 2024. Gains and losses (realized and unrealized) recognized on items measured at fair value on a recurring basis included in earnings are reported within Other gains and (losses) on our consolidated financial statements.

Our other material financial instruments had the following carrying values and fair values as of the dates shown (dollars in thousands):

(a)The carrying value of Senior Unsecured Notes, net (Note 11) includes unamortized deferred financing costs of $29.3 million and $30.2 million at December 31, 2025 and 2024, respectively. The carrying value of Non-recourse mortgages, net includes unamortized deferred financing costs of $0.4 million and $0.5 million at December 31, 2025 and 2024, respectively.
(b)The carrying value of Senior Unsecured Notes, net includes unamortized discount of $29.8 million and $29.9 million at December 31, 2025 and 2024, respectively. The carrying value of Non-recourse mortgages, net includes unamortized discount of $2.4 million and $4.4 million at December 31, 2025 and 2024, respectively.
(c)For those Senior Unsecured Notes for which there are no observable market prices (specifically, our private placement Senior Unsecured Notes (Note 11)), we used a discounted cash flow model that estimates the present value of future loan payments by discounting such payments at current estimated market interest rates. We consider these notes to be within the Level 3 category. For all other Senior Unsecured Notes, we determined the estimated fair value using observed market prices in an open market, which may experience limited trading volume. We consider these notes to be within the Level 2 category.
(d)We determined the estimated fair value of our non-recourse mortgage loans using a discounted cash flow model that estimates the present value of the future loan payments by discounting such payments at current estimated market interest rates. The estimated market interest rates consider interest rate risk and the value of the underlying collateral, which includes quality of the collateral, the credit quality of the tenant/obligor, and the time until maturity.

We estimated that our other financial assets and liabilities, including amounts outstanding under our Senior Unsecured Credit Facility and Unsecured Term Loan due 2029 (Note 11), but excluding finance receivables (Note 6), had fair values that approximated their carrying values at both December 31, 2025 and 2024.

Items Measured at Fair Value on a Non-Recurring Basis (Including Impairment Charges)

We periodically assess whether there are any indicators that the value of our real estate investments may be impaired or that their carrying value may not be recoverable, including investments impacted by the Spin-Off and Office Sale Program (Note 1). Our impairment policies are described in Note 2.
 
The following table presents information about assets for which we recorded an impairment charge and that were measured at fair value on a non-recurring basis (in thousands):

Impairment charges, and their related triggering events and fair value measurements, recognized during 2025, 2024, and 2023 were as follows:

Real Estate

The impairment charges described below are reflected within Impairment charges — real estate in our consolidated statements of income.

2025 — During the year ended December 31, 2025, we recognized impairment charges totaling $70.4 million on 15 properties, respectively, in order to reduce their carrying values to their estimated fair values, which approximated their estimated selling prices. Seven of these properties were self-storage operating properties, all of which were sold during 2025. Three more of these properties were sold in 2025.

2024 — During the year ended December 31, 2024, we recognized impairment charges totaling $23.0 million on four properties in order to reduce their carrying values to their estimated fair values, which approximated their estimated selling prices. Two of these properties were sold in 2024 and two were sold in 2025.

In addition, during the year ended December 31, 2024, we recognized impairment charges totaling $20.6 million on two properties leased to the same tenant due to changes in expected cash flows related to a tenant bankruptcy, in order to reduce their carrying values to their estimated fair values. The fair value measurements for these properties were determined by using the following unobservable inputs:

•Comparable vacant sale prices ranging from $35 per square foot to $36 per square foot; and
•Six months of estimated net cash flows ranging from $0.5 million to $1.0 million.

These properties were sold in 2025.

2023 — During the year ended December 31, 2023, we recorded an impairment charge of $47.3 million related to the 59 properties that were contributed to NLOP in the Spin-Off (Note 3). The fair value measurements for certain of these properties were determined by estimating discounted cash flows using the following unobservable inputs:

•Market rents ranging from $6 per square foot to $65 per square foot;
•Cash flow discount rates ranging from 6.5% to 12.0%; and
•Terminal capitalization rates ranging from 5.5% to 12.0%.

Additionally, the fair value measurements for certain of these properties approximated their estimated selling prices.

The fair value measurements for the non-recourse mortgages encumbering certain of the properties that were contributed to NLOP were determined using a discounted cash flow model that estimates the present value of the future loan payments by discounting such payments at current estimated market interest rates. The estimated market interest rates consider interest rate risk and the value of the underlying collateral, which includes quality of the collateral, the credit quality of the tenant/obligor, and the time until maturity.

In addition, during the year ended December 31, 2023, we recognized impairment charges totaling $39.1 million on three office properties in order to reduce their carrying values to their estimated fair values, which approximated their estimated selling prices. We sold all of these properties during 2023 and 2024.
