(4) Real Estate Investments –

The Partnership leases its properties to tenants under net leases, classified as operating leases. Under a net lease, the tenant is responsible for real estate taxes, insurance, maintenance, repairs and operating expenses for the property. For some leases, the Partnership is responsible for repairs to the structural components of the building, the roof, and the parking lot. At the time the properties were acquired, the remaining primary lease terms varied from 10 to 18 years. The leases provide the tenants with two to four five-year renewal options subject to the same terms and conditions as the primary term. The leases for the Best Buy store, Jared Jewelry store in Auburn Hills and Fresenius Medical Center were extended to end on January 19, 2023, December 31, 2024 and June 30, 2027, respectively.
