Depreciation and amortization expense related to property and equipment was $15.7 million, $17.3 million and $12.1 million for 2021, 2020 and 2019, respectively.

At December 31, 2021, 2020 and 2019, accumulated amortization in connection with internal-use software costs was $42.5 million, $38.7 million and $29.9 million, respectively. In 2021, 2020 and 2019, we recorded amortization expense of $11.6 million, $12.3 million and $7.3 million, respectively, in connection with these costs. Software development in-progress consists primarily of internal-use software projects, which when placed in service, will provide enhancements and improvements to the operational and functional capabilities to our online platforms and our customer-facing website. In 2021 and 2020 we capitalized internal-use software development costs of $9.9 million and $8.1 million, respectively. In 2021, 2020 and 2019, we impaired $0.9 million, $1.1 million and $3.7 million, respectively, of capitalized software developments costs related primarily to internal-use software projects that no longer met our business requirements or were no longer expected to be placed in service.
