[2] As of December 31, 2024, there was $22.7 million of unrecognized compensation cost related to non-vested restricted stock granted under the Parent Company's Plan. When recognized, this compensation results in additional paid in capital in the accompanying Consolidated Statements of Equity of the Parent Company and in general partner preferred and common units in the accompanying Consolidated Statements of Capital of the Operating Partnership. This unrecognized compensation cost is expected to be recognized over the next three years. The Company issues new restricted stock from its authorized shares available at the date of grant.

[4] Time-based awards vest beginning on the first anniversary following the grant date over a one or four year service period. These grants are subject only to continued employment and are not dependent on future performance measures. Accordingly, if such vesting criteria are not met, compensation cost previously recognized is reversed.
[5] Performance-based awards are earned subject to performance measurements. Once the performance criteria are achieved and the actual number of shares earned is determined, shares vest over a required service period. The Company considers the likelihood of meeting the performance criteria based upon management's estimates from which it determines the amounts recognized as expense on a periodic basis.
[6] Market-based awards are earned dependent upon the Company's total shareholder return in relation to the shareholder return of a NAREIT index over a three-year period. Once the performance criteria are met and the actual number of shares earned is determined, the shares are immediately vested and distributed. The probability of meeting the criteria is considered when calculating the estimated fair value on the date of grant using a Monte Carlo simulation. These awards are accounted for as awards with market criteria, with compensation cost recognized over the service period, regardless of whether the performance criteria are achieved and the awards are ultimately earned. The significant assumptions underlying determination of fair values for market-based awards granted were as follows:
