Investments, Debt and Equity Securities [Abstract]
Short-term Investments	SHORT-TERM INVESTMENTSShort-term investments at March 31, 2020 were composed of U.S. Treasury Bills totaling $16.0 million maturing on June 11, 2020 carrying an interest rate of 1.4%. Short-term investments at December 31, 2019 were composed of U.S. Treasury Bills totaling $24.8 million, consisting of $8.9 million that matured on March 12, 2020 and $15.9 million maturing on June 11, 2020. The interest rates on the U.S. Treasury Bills held on December 31, 2019 that matured on March 12, 2020 and maturing on June 11, 2020 were 1.8%, and 1.4%, respectively. These investments are classified as held-to-maturity and recorded at cost plus accrued interest, which approximates fair value. We do not intend to sell these investments, and it is not more likely than not that we will be required to sell the investments before we recover their amortized cost bases.
