Amounts capitalized to internal-use software related to continuing operations for the years ended December 31, 2021 and 2020 were $4,727 and $3,437, respectively.

In the fourth quarter of 2020, the Company’s discussions with and exploration of potential opportunities for its sequencing and molecular analysis solutions indicated that certain internal-use software developed by the Company related to its GPS Cancer product would not be utilized in those arrangements. As a result, the Company determined that the carrying value of these internal-use software assets was not recoverable as of December 31, 2020 and recorded an impairment loss of $729 within impairment of intangible assets, including internal-use software.
