Actual results could differ from those estimates. Management makes significant estimates regarding revenue recognition, purchase price allocations to record investments in real estate, income taxes, derivative financial instruments, hedging activities, equity-based compensation expenses related to multi-year outperformance agreements entered into with the Advisor in 2015 (the “2015 OPP”) and 2018 (the “2018 OPP”) and fair value measurements, as applicable.</span></div>

As of December 31, 2020, these leases had a weighted-average remaining lease term of 8.5 years. Because many of the Company’s leases provide for rental increases at specified intervals, straight-line basis accounting requires the Company to record a receivable for, and include in revenue from tenants, unbilled rents receivable that the Company will only receive if the tenant makes all rent payments required through the expiration of the initial term of the lease. As of December 31, 2020 and 2019, the Company’s cumulative straight-line rents receivable in the consolidated balance sheets was $61.0 million and $51.8 million, respectively. For the years ended December 31, 2020, 2019 and 2018, the Company’s revenue from tenants included impacts of unbilled rental revenue of $7.9 million, $6.8 million and $6.3 million, respectively, to adjust contractual rent to straight-line rent. </span></div>For new leases after acquisition of a property, the commencement date is considered to be the date the lease is executed and the tenant has access to the space. The Company defers the revenue related to lease payments received from tenants in advance of their due dates. When the Company acquires a property, the acquisition date is considered to be the commencement date for purposes of this calculation for all leases in place at the time of acquisition. In addition to base rent, the Company’s lease agreements generally require tenants to pay or reimburse the Company for all property operating expenses, which primarily reflect insurance costs and real estate taxes incurred by the Company and subsequently reimbursed by the tenant. However, some limited property operating expenses that are not the responsibility of the tenant are absorbed by the Company. Under ASC 842, the Company has elected to report combined lease and non-lease components in a single line “Revenue from tenants.” For expenses paid directly by the tenant, under both ASC 842 and 840, the Company has reflected them on a net basis. The Company continually reviews receivables related to rent and unbilled rent receivables and determines collectability by taking into consideration the tenant’s payment history, the credit worthiness and financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located. Under lease accounting rules, the Company is required to assess, based on credit risk only, if it is probable that it will collect virtually all of the lease payments at the lease commencement date and it must continue to reassess collectability periodically thereafter based on new facts and circumstances affecting the credit risk of the tenant. Partial reserves, or the ability to assume partial recovery are no longer permitted. If the Company determines that it is probable it will collect virtually all of the lease payments (rent and common area maintenance), the lease will continue to be accounted for on an accrual basis (i.e. straight-line). However, if the Company determines it is not probable that it will collect virtually all of the lease payments, the lease will be accounted for on a cash basis and the straight-line rent receivable would be written off where it was subsequently concluded that collection was not probable. Cost recoveries from tenants are included in revenue from tenants on the accompanying consolidated statements of operations in the period the related costs are incurred, as applicable.Under ASC 842, uncollectible amounts are reflected as reductions in revenue from tenants. Under ASC 840, the Company recorded such amounts as bad debt expense as part of property operating expenses.
