All held-to-maturity short-term investments at September 30, 2018 and December 31, 2017 will mature in less than one year.  The gross unrealized gains and losses for the Company's commercial paper and overnight repurchase agreement are not significant.  The Company carries short-term investments at amortized cost. The fair value of the short-term investments is determined based on “Level 1” inputs, which consist of quoted prices in active markets for identical assets.
