1 Asset categories were revised and collapsed in the current year. 2018 comparative figures have been reclassified to conform to current year's asset classifications. 2 The measurement of weighted average depreciation rate excludes non-depreciable assets. 3 Certain assets were reclassified as held for sale as at December 31, 2019 and December 31, 2018 (Note 8). Depreciation expense for the years ended December 31, 2019, 2018 and 2017 was $3.0 billion, $2.9 billion and $2.9 billion, respectively. IMPAIRMENT Access Northeast Project In 2019, we announced that we terminated the agreements with Eversource and National Grid related to the Access Northeast project. As a result, we recognized an impairment loss of $105 million for the year ended December 31, 2019, which is included in Impairment of long-lived assets in the Consolidated Statements of Earnings. Access Northeast is part of our Gas Transmission and Midstream segment. Impairment charges were based on the amount by which the carrying values of the assets exceeded fair value, determined using expected discounted future cash flows.
