Long-Term Incentive Plan Units
OP LTIP Units issued under the Company's incentive plans are generally exercisable by the holder at any time after vesting. Each OP LTIP Unit is convertible into an OP Unit on a one-for-one basis. Subject to certain conditions, the OP Units are redeemable by the holder for an equivalent number of shares of common stock of the Company or for the cash value of such shares of common stock, at the Company's election. Costs associated with the OP LTIP Units issued under the Company's incentive plans are measured as of the grant date and expensed ratably over the vesting period. Total expense associated with OP LTIP Units issued under the Company's incentive plans is presented in Compensation and benefits, on the Statement of Operations. Total expense associated with OP LTIP Units issued under the Company's incentive plans for the years ended December 31, 2024, 2023, and 2022 was $1.1 million, $1.3 million, and $1.4 million, respectively.

About Stock Compensation Disclosures

Stock-based compensation disclosures detail the equity awards granted to employees and executives — including stock options, restricted stock units (RSUs), and performance shares — along with the valuation methods and assumptions used to expense them. This section reveals the true cost of talent retention and the alignment between management incentives and shareholder interests.

Key signals: total unrecognized compensation expense and its expected recognition period signal future earnings headwinds from already-granted awards. For stock options, examine Black-Scholes assumptions — expected volatility, risk-free rate, and expected term — as understating any of these reduces reported compensation expense. Compare stock compensation expense as a percentage of revenue against peers to assess dilution cost. Watch vesting schedules for acceleration clauses tied to change-of-control events. Performance-based awards with undemanding targets may indicate weak governance. Add back stock compensation to operating cash flow to calculate a more conservative free cash flow figure.
