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. The contractual maturity of all marketable securities was less than one year as of January 31, 2022 and 2021. As of January 31, 2022, unrealized losses on our U.S. government treasury securities were approximately $3.4 million, net of tax. The changes in market interest rates as of January 31, 2022 have resulted in unrealized losses on these securities. The Company intends to hold these securities to maturity and as a result does not expect to realize these losses in its financial statements. As of January 31, 2021, gross unrealized gains for cash equivalents and short-term investments were not material. The Company concluded that an allowance for credit losses was unnecessary for short-term investments as of January 31, 2022 and 2021. Gross realized gains and losses were not material for each of the years ended January 31, 2022 and 2021.

Convertible Senior Notes

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 its convertible senior notes at January 31, 2022 to be a Level 2 measurement due to limited trading activity of the convertible senior notes. Refer to Note 6, Convertible Senior Notes, to the consolidated financial statements for further details.

Non-marketable Securities

As of January 31, 2022 and 2021, the total amount of non-marketable equity and debt securities included in other assets on the Company’s balance sheets were $4.8 million and $0.5 million, respectively. Refer to Note 2, Summary of Significant Accounting Policies, for further details. The Company classifies these assets as Level 3 within the fair value hierarchy only if an impairment or observable price changes in orderly transactions are recognized on these non-marketable securities during the period. The estimation of fair value for these investments is inherently complex due to the lack of readily available market data and inherent lack of liquidity and requires the Company’s judgment and the use of significant unobservable inputs in an inactive market. In addition, the determination of whether an orderly transaction is for the identical or a similar investment requires significant management judgment, including understanding the differences in the rights and obligations of the investments, the extent to which those differences would affect the fair values of those investments and the stage of operational development of the entities. For the years ended January 31, 2022 and 2021, there have been no adjustments to the carrying values of the Company’s non-marketable securities as a result of impairment or observable price changes.
