Fair Value Disclosures [Abstract]
Fair Value	Fair Value The Company estimates the fair value of its long-term debt primarily using an expected present value technique, which is based on observable market inputs, using interest rates currently available to the Company for instruments with similar terms and remaining maturities. The estimated fair value of the Company’s long-term debt, excluding capital leases and unamortized debt issuance costs, was $2.3 billion as of March 31, 2019, as compared with the gross carrying value of $2.4 billion. If measured at fair value, long-term debt, excluding capital lease obligations, would be classified in Level 2 of the fair value hierarchy. Non-financial assets such as goodwill, tangible assets, intangible assets and other contract related long-lived assets are reduced to fair value in the period an impairment charge is recognized. The fair value measurements, in such instances, would be classified in Level 3. There were no significant impairments recorded during the fiscal years ended March 31, 2019 and 2018.
