Restructuring Costs [Abstract]
Restructuring Plan	17. Restructuring Plan In May 2020, we announced a decision to execute a reduction in our workforce of less than 3% as well as other temporary cost reductions in response to the COVID-19 pandemic. We recorded $2,562 of restructuring costs, consisting of payroll-related costs, such as severance, outplacement costs, and continuing healthcare coverage, associated with the involuntary separation of employees pursuant to a one-time benefit arrangement, in the six months ended September 30, 2020 within operating expenses in our condensed consolidated statements of net income and comprehensive income. These amounts were accrued when it was probable that the benefits would be paid, and the amounts were reasonably estimable. The payroll-related costs were substantially paid as of September 30, 2020. In the three and six months ended September 30, 2019, we recorded $175 and $1,882 of restructuring costs, respectively, consisting primarily of payroll-related costs, such as severance, outplacement costs, and continuing healthcare coverage, associated with the involuntary separation of employees pursuant to a one-time benefit arrangement, as part of a business restructuring plan implemented in June 2019. In connection with the June 2019 restructuring plan, we also vacated portions of certain leased locations and recorded impairments of $1,916 and $2,405 in the three and six months ended September 30, 2019 to our operating right-of-use assets and certain related fixed assets associated with the vacated locations, or portions thereof, in Horsham, St. Louis, Irvine and Atlanta based on projected sublease rental income and estimated sublease commencement dates. The impairment analysis was performed at the asset group level and the impairment charge was estimated by comparing the fair value of each asset group based on the expected cash flows to its respective book value. We determined the discount rate for each asset group based on the approximate interest rate on a collateralized basis with similar remaining terms and payments as of the impairment date. Significant judgment was required to estimate the fair value of each asset group and actual results could vary from the estimates, resulting in potential future adjustments to amounts previously recorded.

17. Restructuring Plan

In May 2020, we announced a decision to execute a reduction in our workforce of less than 3% as well as other temporary cost reductions in response to the COVID-19 pandemic. We recorded $2,562 of restructuring costs, consisting of payroll-related costs, such as severance, outplacement costs, and continuing healthcare coverage, associated with the involuntary separation of employees pursuant to a one-time benefit arrangement, in the six months ended September 30, 2020 within operating expenses in our condensed consolidated statements of net income and comprehensive income. These amounts were accrued when it was probable that the benefits would be paid, and the amounts were reasonably estimable. The payroll-related costs were substantially paid as of September 30, 2020.

In the three and six months ended September 30, 2019, we recorded $175 and $1,882 of restructuring costs, respectively, consisting primarily of payroll-related costs, such as severance, outplacement costs, and continuing healthcare coverage, associated with the involuntary separation of employees pursuant to a one-time benefit arrangement, as part of a business restructuring plan implemented in June 2019. In connection with the June 2019 restructuring plan, we also vacated portions of certain leased locations and recorded impairments of $1,916 and $2,405 in the three and six months ended September 30, 2019 to our operating right-of-use assets and certain related fixed assets associated with the vacated locations, or portions thereof, in Horsham, St. Louis, Irvine and Atlanta based on projected sublease rental income and estimated sublease commencement dates.
