During the year ended March 31, 2022, we vacated portions of certain leased locations and recorded impairments of $3,906 to our right-of-use assets and certain related fixed assets associated with the vacated locations, or portions thereof, in Irvine, Horsham, Atlanta, Fairport, Hunt Valley, Bangalore, and St. Louis based on projected sublease rental income and estimated sublease commencement dates. The impairment analyses were performed at the asset group level and the impairment charges were 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 year ended March 31, 2021, as part of our response to the COVID-19 pandemic and ongoing cost reduction efforts, we vacated our Cary office, portions of our Irvine and Horsham offices, and the remainder of our San Diego office. We recorded impairments of $5,539 to our operating right-of-use assets and certain related fixed assets associated with the vacated locations based on projected sublease rental income and estimated sublease commencement dates and the remeasurement of our operating lease liabilities associated with the modification of certain lease expiration dates.

During the year ended March 31, 2020, we recorded impairments of $9,373 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.
