[1] Operating lease ROU assets are discussed further in Note 5.

[2] Fees related to a commitment obtained in October 2023 for a $1.1 billion mortgage facility to be secured by an originally identified group of 40 properties (the “Mortgage Commitment”). The fees paid to date related to the Mortgage Commitment were recorded as a deferred fee as the facility had not closed and therefore no amounts had been drawn. The Company terminated the Mortgage Commitment in August 2024 when it closed a separate $530.0 million mortgage financing on different terms (Note 6). At termination, when it became probable that the Mortgage Commitment would not be drawn upon, the remaining fees were expensed. For the year ended December 31, 2024, the Company wrote-off $21.2 million of fees relating to the Mortgage Commitment to Debt extinguishment costs on the Company’s consolidated statements of operations.

[3] Included cash flow hedge and derivative on unsecured notes (Note 6).

[4] Includes $1.2 million related to a below-market lease option for the Company’s Beachwood headquarters included in the Separation and Distribution Agreement with Curbline Properties.
