Cash and Cash Equivalents [Abstract]
Investment Impairments	Investment Impairments We have concluded that no material impairment losses existed as of March 31, 2020. In making this determination, we considered the financial condition and prospects of each issuer, the magnitude of the losses compared with the cost, the probability that we will be unable to collect all amounts due according to the contractual terms of the security, the credit rating of the security and our ability and intent to hold these investments until the anticipated recovery in market value occurs.
