[1] We have one 5-year renewal option at existing lease rates (through 2031).

[2] We have one 5-year renewal option at fair market value lease rates (through 2031). Upon the December 31, 2021 expiration of the lease on Wellington Regional Medical Center, a wholly-owned subsidiary of ours exercised its fair market value renewal option and renewed the lease for a 5-year term scheduled to expire on December 31, 2026. On each January 1st through 2026, the annual rent will increase by 2.5% on a cumulative and compounded basis.

[3] We have seven 5-year renewal options at fair market value lease rates (2034 through 2068). On each January 1st through 2033, the annual rent will increase by 2.25% on a cumulative and compounded basis.

[4] This facility is operated by a joint venture in which we are the managing, majority member and an unrelated third-party holds a minority ownership interest. The joint venture has three, 10-year renewal options at computed lease rates as stipulated in the lease (2041 through 2070) and two additional, 10-year renewal options at fair market value lease rates (2071 through 2090). In each January through 2040 (and potentially through 2070 if three, 10-year renewal options are exercised), the annual rental will increase by 2.75% on a cumulative and compounded basis.
