(1) The Company considers all highly liquid instruments with maturities of three months or less at the time of purchase to be cash equivalents. (2) The fair value of the debt securities consisting of U.S. Treasury bills is based on their quoted market prices. The fair value of these financial instruments are classified as Level 1 in the fair value hierarchy. The original purchase of U.S. Treasury bills occurred in September 2018, utilizing the proceeds from the sale of our Core business. (3) ASC 825-10, Financial Instruments, allows entities to voluntarily choose to measure certain financial assets and liabilities at fair value (fair value option). The fair value option may be elected on an instrument-by-instrument basis and is irrevocable, unless a new election date occurs. If the fair value option is elected for an instrument, unrealized gains and losses for that instrument should be reported in earnings within interest income at each subsequent reporting date. At the date of purchase, the Company elected the fair value option for all investments with maturities of three months or greater at the time of purchase.
