We include the UCA associated with each property included above in the estimated UCA of our overall owned residual portfolio, except for the property with the land that is ground leased to us. For more detail on these matters, please see "Risk Factors” filed as Exhibit 99.3 to our Current Report on Form 8-K filed with the SEC on April 4, 2023, which is expressly incorporated herein by reference, as the same may be updated in our subsequent reports filed with the SEC. In particular, please see: “Risk Factors -Our estimated UCA, Combined Property Value and Ground Rent Coverage may not reflect the full potential impact of the COVID-19 pandemic and may decline materially in future periods, -Certain tenant rights under our Ground Leases may limit the value and the UCA we are able to realize upon lease expiration, sale of our land and Ground Leases or other events, -We rely on Property NOI as reported to us by our tenants, -Our estimates of Combined Property Value are based on various assumptions and information supplied to us by our tenants, and accordingly may not be indicative of actual values, and –There can be no assurance that we will realize any incremental value from the UCA in our owned residual portfolio or that the market price of our common stock will reflect any value attributable thereto."

During the third quarter of 2018, we adopted, and in the second quarter of 2019, our stockholders approved, the Caret Performance Incentive Plan (the “Original Caret Performance Incentive Plan”). Under the Original Caret Performance Incentive Plan, 1,500,000 Caret units were reserved for grants of performance-based awards to Original Caret Performance Incentive Plan participants, including certain executives of iStar, or its affiliates, and our directors and service providers. Initial grants under the Original Caret Performance Incentive Plan were subject to graduated vesting based on time-based service conditions and hurdles of our common stock price, all of which were satisfied as of December 31, 2022, except with respect to approximately 1,000 Caret units scheduled to vest on December 31, 2023. In connection with the Merger, certain of our executive officers have entered into re-vesting agreements pursuant to which the executives have agreed to subject 25% of their previously vested Caret units to additional vesting conditions which will be satisfied on the second anniversary of the Merger, subject to the applicable executive’s continued employment through such date. In connection with the Merger, Safehold Operating Partnership LP converted from a Delaware limited partnership into a Delaware limited liability company and changed its name to “Safehold GL Holdings LLC” (“Portfolio Holdings”), with us as its managing member, and each Award Agreement (as defined in the Original Caret Performance Incentive Plan) related to outstanding Caret unit awards was assigned to Portfolio Holdings. Following such assignment, we amended and restated the Original Caret Performance Incentive Plan (the “Caret Performance Incentive Plan”). Following the merger, 76,801 Caret units were awarded to executive officers and other employees under such plan that are subject to cliff vesting on the fourth anniversary of their grant date if our common stock has traded at an average price of $60.00 or more for at least 30 consecutive trading days during that four year period. As a result, as of March 31, 2023, vested and unvested Caret units beneficially owned by our officers and other employees represent approximately 15.41% of the outstanding Caret units and 12.50% of the authorized Caret units.
In addition to the Caret units awarded or reserved for issuance under our Caret Performance Incentive Plan, as of April 26, 2023, we have sold or contracted to sell an aggregate of 259,642 Caret units to third-party investors, including affiliates of MSD Partners L.P. (“MSD”) and an entity affiliated with one of our independent directors. As a result, we currently own the remaining 82.2% of the outstanding Caret units.
In connection with the sale of 137,142 Caret units in February 2022 (28,571 of which were committed to be purchased at the time, but have not yet closed), we agreed to use commercially reasonable efforts to provide public market liquidity for such Caret units by seeking to provide a listing of the Caret units (or securities into which they may be exchanged) on a public exchange within two years of the sale. In the event market liquidity of such Caret units is not achieved within such two year period at a valuation not less than the purchase price for the Caret units purchased in February 2022, reduced by an amount equal to the amount of subsequent cash distributions made to investors on account of such Caret units, then the investors in the February 2022 transaction have the right to cause their Caret units purchased in February 2022 to be redeemed by Portfolio Holdings at such purchase price as so reduced. On March 31, 2023, we sold 100,000 Caret units to affiliates of MSD Partners for an aggregate purchase price of $20.0 million and sold an aggregate of 22,500 Caret units to other third-party investors for an aggregate $4.5 million, in each case with no redemption option.
