Restructuring Costs [Abstract]
Restructuring Plan	16. Restructuring Plan In June 2019, we implemented a business restructuring plan as part of our continued efforts to preserve and grow the value of the Company through client-focused innovations while reducing our cost structure. As part of the restructuring, we reduced our total workforce by approximately 4% primarily within the research and development function and intend to expand on our research and development resources in India. We recorded $2,505 of restructuring costs in the year ended March 31, 2020 within operating expenses in our consolidated statements of comprehensive income. The restructuring costs consisted 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. These amounts were accrued when it was probable that the benefits would be paid, and the amounts were reasonably estimable. The payroll-related costs have been substantially paid as of March 31, 2020. In connection with the restructuring plan, we also vacated portions of certain leased locations and recorded impairments of $9,373 in the year ended March 31, 2020 to our operating right-of-use assets and certain related fixed assets associated with the vacated locations, or portions thereof, in North Canton, San Diego, Horsham, St. Louis, Irvine, Atlanta, Brentwood, and Phoenix, based on projected sublease rental income and estimated sublease commencement dates. We are actively marketing each of these vacated locations for sublease. 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. During the years ended March 31, 2019 and 2018, we recorded $640 and $611, respectively, of restructuring costs related to adjustments to the estimated fair value of remaining lease obligations for vacated properties associated with our prior restructuring plan. The restructuring costs were comprised of facilities-related costs associated with accruals for the remaining lease obligations at certain locations, including Solana Beach, Costa Mesa, and a portion of Horsham with contractual lease terms ending between January 2018 and September 2023. We estimated the remaining lease obligations at fair value as of the cease-use date for each location based on the future contractual lease obligations, reduced by projected sublease rentals that could be reasonably obtained for the locations after a period of marketing, and adjusted for the effect deferred rents that have been recognized under the lease. The effect of discounting future cash flows using a credit-adjusted risk free rate was not significant. Sublease income and commencement dates were estimated based on data available from rental activity in the local markets. As of March 31, 2019, the remaining lease obligation, net of estimated projected sublease rentals, was $1,762. Refer to Note 5 for estimated timing of payments related to remaining lease obligations.

16. Restructuring Plan

In June 2019, we implemented a business restructuring plan as part of our continued efforts to preserve and grow the value of the Company through client-focused innovations while reducing our cost structure. As part of the restructuring, we reduced our total workforce by approximately 4% primarily within the research and development function and intend to expand on our research and development resources in India. We recorded $2,505 of restructuring costs in the year ended March 31, 2020 within operating expenses in our consolidated statements of comprehensive income. The restructuring costs consisted 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. These amounts were accrued when it was probable that the benefits would be paid, and the amounts were reasonably estimable. The payroll-related costs have been substantially paid as of March 31, 2020.

In connection with the restructuring plan, we also vacated portions of certain leased locations and recorded impairments of $9,373 in the year ended March 31, 2020 to our operating right-of-use assets and certain related fixed assets associated with the vacated locations, or portions thereof, in North Canton, San Diego, Horsham, St. Louis, Irvine, Atlanta, Brentwood, and Phoenix, based on projected sublease rental income and estimated sublease commencement dates.
