Topic 842 did not significantly change our accounting policy for recognizing rental revenues and tenant recoveries, and we adopted a practical expedient which allows us to account for our rental revenues and tenant recoveries on a combined basis. Rental revenues and tenant recoveries from tenant leases are included in Rental revenues and tenant recoveries in the consolidated statements of operations. All of our tenant leases are classified as operating leases. For lease terms exceeding one year, rental income is recognized on a straight-line basis over the lease term. Tenant receivables consist primarily of amounts due for contractual lease payments and reimbursements of common area maintenance expenses, property taxes, and other costs recoverable from tenants. Deferred rent receivables represent the amount by which the cumulative straight-line rental revenue recorded to date exceeds the cumulative cash rents billed to date under the lease agreement. Rental revenue from month-to-month leases or leases with no scheduled rent increases or other adjustments is recognized on a monthly basis when earned. </span></div><div style="text-align:justify;text-indent:18pt"><span><br/></span></div><div style="text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Lease termination fees, which are included in Rental revenues and tenant recoveries in the consolidated statements of operations, are recognized on a straight line basis over the new remaining lease term when the related lease is canceled. We recognized lease termination revenue of $1.0 million, $0.5 million and $1.6 million during 2020, 2019 and 2018, respectively.</span></div><div style="text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> </span></div><div style="text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Tenant improvements constructed, and owned by us, and reimbursed by tenants are recorded as our assets, and the related revenue, which are included in Rental revenues and tenant recoveries in the consolidated statements of operations, is recognized over the related lease term. We recognized revenue for reimbursement of tenant improvements of $5.9 million, $5.8 million and $3.5 million during 2020, 2019 and 2018, respectively.</span></div><div style="text-align:justify;text-indent:18pt"><span><br/></span></div><div style="text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> Estimated tenant recoveries for real estate taxes, common area maintenance and other recoverable operating expenses, which are included in Rental revenues and tenant recoveries in the consolidated statements of operations, are recognized as revenue on a gross basis in the period that the recoverable expenses are incurred. Subsequent to year-end, we perform reconciliations on a lease-by-lease basis and bill or credit each tenant for any differences between the estimated expenses we billed to the tenant and the actual expenses incurred.</span></div><div style="text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In accordance with Topic 842, we perform an assessment as to whether or not substantially all of the amounts due under a tenant’s lease agreement is deemed probable of collection. This assessment involves using a methodology that requires judgment and estimates about matters that are uncertain at the time the estimates are made, including tenant specific factors, specific industry conditions, and general economic trends and conditions.</span></div><div style="text-align:justify;text-indent:18pt"><span><br/></span></div><div style="text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For leases where we have concluded it is probable that we will collect substantially all the lease payments due under those leases, we continue to record lease income on a straight-line basis over the lease term. For leases where we have concluded that it is not probable that we will collect substantially all the lease payments due under those leases, we limit the lease income to the lesser of the income recognized on a straight-line basis or cash basis. If our conclusion of collectibility changes, we will record the difference between the lease income that would have been recognized on a straight-line basis and cash basis as a current-period adjustment to rental revenues and tenant recoveries. We write-off tenant receivables and deferred rent receivables as a charge against rental revenues and tenant recoveries in the period we conclude that substantially all of the lease payments are not probable of collection. If we subsequently collect amounts that were previously written off then the amounts collected are recorded as an increase to our rental revenues and tenant recoveries in the period they are collected. Charges for uncollectible amounts, related to tenant receivables and deferred rent receivables, which for the year ended December 31, 2020 were primarily due to the impact of the COVID-19 pandemic, reduced our office revenues by $41.0 million and $2.6 million for the years ended December 31, 2020 and 2019, respectively. </span></div>Before the adoption of Topic 842, we presented our tenant receivables and deferred rent receivables net of allowances on our consolidated balance sheets. We considered many factors when evaluating the level of allowances necessary, including evaluations of individual tenant receivables, historical loss activity, current economic conditions and other relevant factors. We generally obtain letters of credit or security deposits from our tenants.
