Operating lease costs are recorded on a straight-line basis over the lease term. The change in operating lease costs for the three months ended March 31, 2020 when compared to the three months ended March 31, 2019 is due to the impairment on operating right-of-use assets recognized during the three months ended December 31, 2019. For operating leases that have been impaired, the lease liability continues to amortize using the same effective interest method as before the impairment charge and the operating right-of-use asset is amortized on a straight-line basis. Finance lease costs include amortization of the right-of-use assets and interest on lease liabilities. The components of lease costs, which were included in loss from operations in our Condensed Consolidated Statements of Loss, were as follows:
