Depreciation expense for the years ended December 31, 2019, 2018 and 2017 was $100.0 million, $101.7 million and $94.3 million, respectively.

There were no capitalized leases included in buildings and improvements and machinery and equipment at December 31, 2019 and 2018.

We capitalize interest on borrowings during the active construction period of major capital projects. Capitalized interest is added to the cost of the underlying assets and is amortized over the useful lives of the assets. Capitalized interest for the years ended December 31, 2019, 2018 and 2017 was $1.0 million, $0.9 million and $2.7 million, respectively.

During 2019 and 2018, as part of our 2018 restructuring plan, we recorded within other (income) expense $0.3 million and $2.2 million, respectively, for non-cash asset write-downs associated with the discontinued use of certain equipment. During 2019 and 2018, as part of our restructuring plans, we recorded within other (income) expense $1.9 million and $1.1 million, respectively, for gains on the sale of fixed assets.
