Depreciation expense was $3.1 million for the three months ended September 30, 2019 and 2018 and was $9.3 million and $9.5 million for the nine months ended September 30, 2019 and 2018, respectively, which is recorded in cost of sales, selling, general and administrative expenses and research and development expenses in the Condensed Consolidated Statements of Income.

We review long-lived assets used in operations for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable and the undiscounted cash flows estimated to be generated by the asset are less than the asset’s carrying value. During the three and nine months ended September 30, 2019, the Company recognized impairment charges of $3.9 million related to the abandonment of certain information technology projects in which we had previously capitalized costs related to these projects. The impairment charges were determined based on actual costs incurred as part of the projects.
