Marketable Securities
MARKETABLE SECURITIES	NOTE 7. MARKETABLE SECURITIES As of December 31, 2019, and December 31, 2018, our marketable securities consisted of certificates of deposit and, due to their short-term nature, the fair value of these securities approximated their carrying values which were $2.6 million and $2.5 million at December 31, 2019 and 2018, respectively. The maturities of our certificates of deposit as of December 31, 2019 ranged from March 18, 2020 to October 17, 2020. The value and liquidity of the marketable securities we hold are affected by market conditions, as well as the ability of the issuers of such securities to make principal and interest payments when due, and the functioning of the markets in which these securities are traded. As of December 31, 2019, we do not believe any of the underlying issuers of our marketable securities are at risk of default.
