Base rental income is recognized using the straight-line method over the term of the lease to the extent that lease payments are considered collectible and the lease provides for specific contractual escalators. The Company reviews its operating lease receivables for collectibility on a regular basis, taking into consideration changes in factors such as the tenant’s payment history, the financial condition of the tenant, business conditions in which the tenant operates and economic conditions in the area where the property is located. In the event that collectibility with respect to any tenant is not probable, a direct write-off of the receivable is made as an adjustment to rental income and any future rental revenue is recognized only when the tenant makes a rental payment.</span></div><div style="text-align:justify;text-indent:13.5pt"><span><br/></span></div><div style="text-align:justify;text-indent:13.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">On July 30, 2021, Atria Senior Living acquired the management services of the legacy Holiday Retirement (“Holiday”) portfolio who is the tenant for 17 independent living facilities leased pursuant to a master lease.
