The Company’s investments may, at any time, consist of money market funds, U.S. treasury and U.S. government agency securities, high-quality corporate notes and bonds, commercial paper, non-U.S. government agency securities, and taxable and tax-exempt municipal notes. The Company regularly reviews the securities in an unrealized loss position and evaluates the current expected credit loss by considering factors such as historical experience, market data, financial condition and near-term prospects of the investee, the extent of the loss related to the credit of the issuer, and the expected cash flows from the security. The Company segments its portfolio based on the underlying risk profiles of the securities and has a zero-loss expectation for U.S. treasury and U.S. government agency securities. The basis for this assumption is that these securities have consistently high credit ratings by rating agencies, have a long history with no credit losses, are explicitly guaranteed by a sovereign entity, which can print its own currency, and are denominated in a currency that is routinely held by central banks, used in international commerce, and commonly viewed as a reserve currency. Additionally, all of the Company’s investments in corporate debt securities and municipal securities are in securities with high-quality credit ratings, which have historically experienced low rates of default.

The current unrealized losses on the Company’s available-for-sale debt securities were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. As of June 30, 2025, the Company does not intend to sell the investments in unrealized loss positions, and it is not more-likely-than-not that the Company will be required to sell any of the investments before recovery of their amortized cost basis, which may be at maturity. Therefore, the Company does not expect to realize any losses on these available-for-sale debt securities. Additional factors considered in determining the treatment of unrealized losses include the financial condition and near-term prospects of the investee, the extent of the loss related to the credit of the issuer, and the expected cash flows from the security.

Equity Investments

The Company’s equity investments may, at any time, consist of equity investments with and without readily determinable fair values. The Company generally recognizes equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer.

The following table is a summary of the activity related to equity investments (in millions):


									Reported as:
	December 31, 2024 Carrying Value		Changes in Fair Value		Purchases / Sales / Other (1)		June 30, 2025 Carrying Value		Prepaids and other current assets		Intangible and other assets, net

Equity investments without readily determinable fair value (Level 2)	$	84.6	$	(5.0)	$	6.4	$	86.0	$	—	$	86.0


(1) Other includes foreign currency translation gains/(losses).

For the six months ended June 30, 2025, the Company did not hold any equity investments with readily determinable fair values (Level 1).

For the six months ended June 30, 2025, the Company recognized a net decrease in fair value of $5.0 million, primarily due to impairments and net decreases in observable price changes for certain equity investments, in interest and other income, net.

Foreign Currency Derivatives

The objective of the Company’s hedging program is to mitigate the impact of changes in currency exchange rates on net cash flow from foreign currency-denominated sales, expenses, intercompany balances, and other monetary assets or liabilities denominated in currencies other than the U.S. dollar (“USD”). The terms of the Company’s derivative contracts are generally thirteen months or shorter. The derivative assets and liabilities are measured using Level 2 fair value inputs.

Cash Flow Hedges

The Company enters into currency forward contracts as cash flow hedges to hedge certain forecasted revenue transactions denominated in currencies other than the USD, primarily the Euro (“EUR”), the British Pound (“GBP”), the Japanese Yen (“JPY”), the Korean Won (“KRW”), the New Taiwan Dollar (“TWD”), and the Indian Rupee (“INR”). The Company also enters into currency forward contracts as cash flow hedges to hedge certain forecasted expense transactions denominated in EUR and the Swiss Franc (“CHF”).

For these derivatives, the Company reports the unrealized after-tax gain or loss from the hedge as a component of accumulated other comprehensive income (loss) in stockholders’ equity and reclassifies the amount into earnings in the same period in which the hedged transaction affects earnings. The amounts reclassified to revenue and expenses related to the hedged transactions and the ineffective portions of cash flow hedges were not material for the three and six months ended June 30, 2025, and 2024.

Other Derivatives Not Designated as Hedging Instruments

Other derivatives not designated as hedging instruments consist primarily of forward contracts that the Company uses to hedge intercompany balances and other monetary assets or liabilities denominated in currencies other than the USD, primarily the EUR, GBP, JPY, KRW, CHF, TWD, INR, the Mexican Peso (“MXN”), and the Chinese Yuan (“CNY”).

These derivative instruments are used to hedge against balance sheet foreign currency exposures. The related gains and losses were as follows (in millions):


	Three Months Ended June 30,				Six Months Ended June 30,
	2025		2024		2025		2024
Recognized gains (losses) in interest and other income, net	$	(24.8)	$	11.8	$	(35.3)	$	30.1
Foreign exchange gains (losses) related to balance sheet re-measurement	$	18.8	$	(13.2)	$	26.5	$	(32.6)

The notional amounts for derivative instruments provide one measure of the transaction volume. Total gross notional amounts (in USD) for outstanding derivatives and the aggregate gross fair value at the end of each period were as follows (in millions):


	Derivatives Designated as Hedging Instruments				Derivatives Not Designated as Hedging Instruments
	June 30, 2025		December 31, 2024		June 30, 2025		December 31, 2024
Notional amounts:
Forward contracts	$	454.0	$	382.2	$	760.0	$	693.5
Gross fair value recorded in:
Prepaids and other current assets	$	3.1	$	14.9	$	3.6	$	13.0
