Share-Based Payment Arrangement [Abstract]

Share and Unit-Based Plans

Share and Unit-Based Plans:Under the Long-Term Incentive Plan ("LTIP"), each award recipient is issued a form of operating partnership units ("LTIP Units") in the Operating Partnership or form of restricted stock units (together with the LTIP Units, the "LTI Units"). Upon the occurrence of specified events and subject to the satisfaction of applicable vesting conditions, LTIP Units (after conversion into OP Units) are ultimately redeemable for common stock of the Company, or cash at the Company's option, on a one-unit for one-share basis. LTI Units receive cash dividends based on the dividend amount paid on the common stock of the Company. The LTIP may include market-indexed awards, performance-based awards and service-based awards.

The market-indexed LTI Units vest over the service period of the award based on the percentile ranking of the Company in terms of total return to stockholders (the "Total Return") per share of common stock relative to the Total Return of a group of peer REITs, as measured at the end of the measurement period. The performance-based LTI Units vest over a specified period based on the Company's operational performance over that period.

During the nine months ended September 30, 2023, the Company granted the following LTI Units:

Grant Date	Units	Type	Fair Value per LTI Unit		Vest Date
1/1/2023	577,255	Service-based	$	11.26	12/31/2025
1/1/2023	1,030,077	Performance-based	$	10.97	12/31/2025
	1,607,332

The fair value of the service-based LTI Units was determined by the market price of the Company's common stock on the date of grant. The fair value (Level 3 measurement) of the performance-based LTI Units granted on January 1, 2023 was estimated on the date of grant using a Monte Carlo Simulation model that assumed a three-year risk-free interest rate of 4.21% and an expected volatility of 74.23%.

The following table summarizes the activity of the non-vested LTI Units, phantom stock units and stock units:
