Award Timing Disclosures [Line Items]
Award Timing MNPI Disclosure	Prior to the Merger, with respect to LTI, the Committee set the grant date for restricted stock, LTIP Unit, and stock option grants at the time of its final compensation determination, generally in late January or early February, although for 2024 determined to make those grants on January 1, 2024. The date of determination and date of award were not selected based on share price. In the case of new-hire packages that included Equity Awards, grants were made on the employee’s start date or on a date designated in advance based on the passage of a specific number of days after the employee’s start date. For non-executive officers, the Committee delegated the authority to make Equity Awards, up to certain limits, to the Chief Financial Officer (Mr. Beldin) and/or Corporate Secretary (Ms. Cohn). Although, we did not have a formal policy, the Committee and Mr. Beldin and Ms. Cohn made grants without regard to the share price or the timing of the release of material non-public information and did not make grants for the purpose of affecting the value of executive compensation. Subsequent to the Merger, the Operating Partnership does not expect to grant any Equity Awards: accordingly, it does not have a policy on the timing of Equity Awards in relation to material non-public information.
