Investments | NOTE 4 – INVESTMENTS Cash and cash equivalents include investments in money market funds that are valued based on the net asset value of the funds. The investments in these funds were $99.2 million and $69.8 million as of December 31, 2019 and 2018, respectively. All other investments are classified as held-to-maturity and consist of highly liquid instruments including primarily corporate bonds and commercial paper. As of December 31, 2019 and 2018, the amortized cost of these investments equaled the net carrying value, which was $38.0 million and $10.1 million, respectively. All held-to-maturity securities as of December 31, 2019 mature in one year or less. See Note 9, Fair Value Measurements, for additional information.
