Fair Value Measurements | Fair Value Measurements The following tables present information about the Company’s financial assets that have been measured at fair value on a recurring basis as of April 30, 2024 and January 31, 2024 and indicate the fair value hierarchy of the valuation inputs utilized to determine such fair value (in thousands): Fair Value Measurement as of April 30, 2024 Level 1 Level 2 Level 3 Total Financial Assets: Cash and cash equivalents: Money market funds $ 477,496 $ — $ — $ 477,496 Short-term investments: U.S. government treasury securities 1,258,292 — — 1,258,292 Prepaid expenses and other current assets: Derivative asset — 170,215 — 170,215 Total financial assets $ 1,735,788 $ 170,215 $ — $ 1,906,003 Fair Value Measurement as of January 31, 2024 Level 1 Level 2 Level 3 Total Financial Assets: Cash and cash equivalents: Money market funds $ 512,456 $ — $ — $ 512,456 Short-term investments: U.S. government treasury securities 1,212,448 — — 1,212,448 Total financial assets $ 1,724,904 $ — $ — $ 1,724,904 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 following table summarizes the amortized cost and fair value of the Company’s short-term investments by remaining contractual maturity as of April 30, 2024 and January 31, 2024 (in thousands): April 30, 2024 January 31, 2024 Amortized Unrealized Fair Value Amortized Unrealized Fair Value Due within one year $ 676,643 $ (1,758) $ 674,885 $ 520,006 $ (543) $ 519,463 Due after one year and within three years 588,959 (5,552) 583,407 690,211 2,774 692,985 Total short-term investments $ 1,265,602 $ (7,310) $ 1,258,292 $ 1,210,217 $ 2,231 $ 1,212,448 As of April 30, 2024, unrealized losses on the Company’s U.S. government treasury securities were approximately $7.3 million. As of January 31, 2024, unrealized gains on the Company’s U.S. government treasury securities were approximately $2.2 million. These unrealized gains and losses were caused by fluctuations in interest rates, which results in changes to the market value of these securities. Because the decline in fair value is due to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity, the Company concluded that an allowance for credit losses was unnecessary for short-term investments as of April 30, 2024. Gross realized gains and losses were not material for both the three months ended April 30, 2024 and 2023. There were no short-term investments in a continuous loss position for greater than twelve months. Convertible Senior Notes and Capped Calls 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 as of April 30, 2024 to be a Level 2 measurement due to limited trading activity of the convertible senior notes. The fair value measurements for the derivative asset related to the Capped Calls associated with the 2024 Notes are determined using the Black-Scholes option-pricing model with Level 1 and Level 2 inputs. The derivative asset was recognized as a result of the Company electing to cash settle the Capped Calls associated with the 2024 Notes (as defined herein). Refer to Note 5, Convertible Senior Notes , for further details on the convertible senior notes and Capped Calls. Non-marketable Securities As of April 30, 2024 and January 31, 2024, the total amount of non-marketable equity and debt securities included in other assets on the Company’s condensed consolidated balance sheets was $12.9 million. The Company did not make additional investments during the three months ended April 30, 2024 and invested an additional $1.3 million of its cash in non-marketable equity securities during the three months ended April 30, 2023. The Company recognized an immaterial net unrealized loss during the three months ended April 30, 2024 on certain of these non-marketable securities and net unrealized gain of $2.2 million during the three months ended April 30, 2023. Refer to Note 2, Summary of Significant Accounting Policies , in the Notes to Consolidated Financial Statements included in Part II, Item 8 of the Company’s 2024 Form 10-K for further information. The Company considers these assets as Level 3 within the fair value hierarchy when 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. |
