[1] We monitor the collectability of all unpaid rent amounts. The onset of COVID-19 and the anticipated economic slowdown resulted in a $2.9 million write-off of accrued straight-line rent during the three months ended March 31, 2020. Additionally, we wrote-off the related deferred leasing costs of $2.2 million during the three months ended March 31, 2020. The write-offs of deferred leasing costs are recorded in depreciation and amortization in our condensed consolidated statements of operations.
