The aggregate related fair value of the corporate debt securities with unrealized losses was $2.4 billion as of March 31, 2023, of which $1.9 billion were in an unrealized loss position for more than 12 months and $420.2 million were in an unrealized loss position for less than 12 months. The aggregate related fair value of corporate debt securities with unrealized losses was $2.7 billion as of December 31, 2022, of which $2.0 billion were in an unrealized loss position for more than 12 months and $620.5 million were in an unrealized loss position for less than 12 months. Unrealized losses related to other investments as of March 31, 2023, and December 31, 2022, were not significant.

The Company's primary objective when investing excess cash is preservation of capital, hence the Company's marketable securities primarily consist of U.S. Treasury Securities, non-U.S government securities, high credit quality corporate debt securities and commercial paper. Because the Company views its marketable securities as available to support current operations, it has classified all available for sale securities as short-term. As of March 31, 2023, and December 31, 2022, for all fixed income securities that were in unrealized loss positions, the Company has determined that (i) it does not have the intent to sell any of these investments, and (ii) it is not more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. In addition, as of March 31, 2023, and December 31, 2022, the Company anticipates that it will recover the entire amortized cost basis of such fixed income securities before maturity.

Interest earned on marketable securities was $17.2 million and $15.6 million in the three months ended March 31, 2023 and 2022, respectively. The interest is recorded as other income (expenses), net, in the accompanying condensed consolidated statements of operations.

The following table summarizes the contractual maturities of marketable securities:


	As of March 31, 2023				As of December 31, 2022
	Amortized Cost		Aggregate Fair Value		Amortized Cost		Aggregate Fair Value
Financial Assets:	(In thousands)

Strategic Investments

As of March 31, 2023, and December 31, 2022, the Company held strategic investments with a carrying value of $30.7 million and $76.9 million, respectively, recorded as other long-term assets in the accompanying condensed consolidated balance sheets. The carrying value of these securities is determined under the measurement alternative on a non-recurring basis and adjusted for observable changes in fair value or impairment. In the three months ended March 31, 2023, the Company remeasured one of its strategic investments that it acquired in 2021 to fair value due to an assessed impairment. The fair value measurement of the strategic investment is categorized under Level 2 in the fair value hierarchy and the primary input used in the fair value measurement was the publicly available stock price of the issuer’s unrestricted security of the same class. The impairment loss of $46.2 million is recorded in other income (expenses), net, in the accompanying condensed consolidated statement of operations for the three months ended March 31, 2023. There were no other impairments or adjustments recorded in the three months ended March 31, 2023 and 2022, related to these securities.

Financial Liabilities

The Company’s financial liabilities that are measured at fair value on a recurring basis consist of foreign currency derivative liabilities and are classified as Level 2 financial instruments in the fair value hierarchy. As of March 31, 2023, and December 31, 2022, the aggregate fair value of these liabilities and the associated unrealized losses were not significant.

The Company’s financial liabilities that are not measured at fair value on a recurring basis are its Senior Notes due 2029 (“2029 Notes”) and its Senior Notes due 2031 (“2031 Notes”). As of March 31, 2023, the fair value of the 2029 Notes and 2031 Notes were $437.4 million and $427.5 million, respectively. As of December 31, 2022, the fair value of the 2029 Notes and 2031 Notes were $410.9 million and $399.4 million, respectively.
