Fair Value of Financial Instruments
Our estimates of the fair value of financial instruments were determined using available market information and widely used valuation methods.  Considerable judgment is necessary to interpret market data and determine an estimated fair value.  The use of different market assumptions or valuation methods may have a material effect on the estimated fair values. The FASB fair value framework hierarchy distinguishes between assumptions based on market data obtained from sources independent of the reporting entity, and the reporting entity’s own assumptions about market-based inputs.  The hierarchy is as follows:
Level 1 - inputs utilize unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2 - inputs are observable either directly or indirectly for similar assets and liabilities in active markets.
Level 3 - inputs are unobservable assumptions generated by the reporting entity.

As of December 31, 2025, we did not have any fair value estimates of financial instruments using Level 3 inputs.

Financial instruments disclosed at fair value

Short term financial instruments

The carrying amounts for cash and cash equivalents, tenant receivables, interest payable, accounts payable, security deposits and dividends payable approximate fair value because of the short-term nature of these instruments.

Secured notes payable

See Note 8 for the details of our secured notes payable. We estimate the fair value of our consolidated secured notes payable by calculating the credit-adjusted present value of the principal and interest payments for each secured note payable. The calculation incorporates observable market interest rates which we consider to be Level 2 inputs, assumes that the loans will be outstanding through maturity, and includes any maturity extension options. The table below presents the estimated fair value and carrying value of our secured notes payable, the carrying value includes unamortized loan premium/discount and excludes unamortized deferred loan fees:

(In thousands)December 31, 2025December 31, 2024
Fair value$5,566,229 $5,429,586 
Carrying value$5,594,452 $5,524,643 


Ground lease liability

See Note 4 for the details of our ground lease. We estimate the fair value of our ground lease liability by calculating the present value of the future lease payments disclosed in Note 4 using our incremental borrowing rate. The calculation incorporates observable market interest rates which we consider to be Level 2 inputs. The table below presents the estimated fair value and carrying value of our ground lease liability:

(In thousands)December 31, 2025December 31, 2024
Fair value$4,301 $3,764 
Carrying value$10,808 $10,822 
Financial instruments measured at fair value on a recurring basis

Derivative instruments

See Note 10 for the details of our derivatives. We present our derivatives on our consolidated balance sheets at fair value, on a gross basis, excluding accrued interest.  We estimate the fair value of our derivative instruments by calculating the credit-adjusted present value of the expected future cash flows of each derivative.  The calculation incorporates the contractual terms of the derivatives, observable market interest rates which we consider to be Level 2 inputs, and credit risk adjustments to reflect the counterparty's as well as our own non-performance risk. Our derivatives are not subject to master netting arrangements.  See Note 2 for our accounting policy for derivative instruments regarding the impact of the changes in fair value measurements on our financial statements.

The table below presents the estimated fair value of our derivatives.

Derivatives Liabilities:

___________________________________________________________________________________
(1)    Consolidated derivatives, which reflect 100%, not our pro-rata share, of our consolidated JVs' derivatives, are included in interest rate contracts on our consolidated balance sheets. The fair values exclude accrued interest which is included in interest payable on our consolidated balance sheets.
(2)    We consolidated Partnership X commencing on January 1, 2025. See Note 3. For the comparable period, the unconsolidated Fund's derivatives, reflect 100%, not our pro-rata share, of our unconsolidated Fund's derivatives. Our pro-rata share of the amounts related to the unconsolidated Fund's derivatives is included in our Investment in unconsolidated Fund on our consolidated balance sheets. See Note 6 for more information about Partnership X, including our equity interest percentage.

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
