The Company utilized the market approach and Level 1 valuation inputs to value its money market mutual funds and U.S. government treasury securities because published net asset values were readily available. As of January 31, 2020 and 2019, gross realized and unrealized gains and losses for cash equivalents and short-term investments were not material and the contractual maturity of all marketable securities was less than one year.
In addition to its cash, cash equivalents and short-term investments, the Company measures the fair value of its outstanding convertible senior notes on a quarterly basis for disclosure purposes. The Company considers the fair value of the convertible senior notes at January 31, 2020 to be a Level 2 measurement due to limited trading activity of the convertible senior notes. Refer to Note 7, Convertible Senior Notes, to the consolidated financial statements for further details.
