Investment securities and fair value measurements

Note 3. Investment securities and fair value measurements

Certain of the Company’s assets and liabilities are recorded at fair value, as described below.

The following tables set forth the Company’s financial instruments that were measured at fair value on a recurring basis by level within the fair value hierarchy:


	December 31, 2022
(in thousands)	Level 1		Level 2		Level 3		Total
Cash equivalents (money market funds)	$	92,850	$	—	$	—	$	92,850
U.S. government agency bonds		-		267,748		-	$	267,748
U.S. treasury bonds		186,477		-		-	$	186,477
Corporate debt securities		-		5,349		-	$	5,349
Totals	$	279,327	$	273,097	$	—	$	552,424


	December 31, 2021
(in thousands)	Level 1		Level 2		Level 3		Total
Cash equivalents (money market funds)	$	797,448	$	—	$	—	$	797,448
Totals	$	797,448	$	—	$	—	$	797,448

Cash equivalents consist of money market funds, which are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in an active market. U.S. treasury securities are also classified as Level 1 because they are valued using quoted prices. U.S. government agency and corporate securities are classified within Level 2 of the fair value hierarchy because they are valued using market-based models that consider inputs such as yield, prices of comparable securities, coupon rate, maturity, and credit quality.

During the periods presented, the Company has not changed the manner in which it values assets and liabilities that are measured at fair value. The Company recognizes transfers between levels of the fair value hierarchy as of the end of the reporting period. There were no transfers within the hierarchy during the years ended December 31, 2022 and 2021.

The Company's fixed income securities held as of December 31, 2022 are classified as available-for-sale. The following table presents the amortized cost, fair value, and unrealized losses by major security type, for the fixed income securities held by the Company:


	December 31, 2022
(in thousands)	Amortized cost		Gross unrealized gains in AOCI		Gross unrealized losses in AOCI			Fair value
U.S. government agency bonds	$	254,881	$	87	$	(211	)	$	254,757
U.S. treasury bonds		186,496		19		(37	)		186,478
Corporate debt securities		5,358		-		(9	)		5,349
Totals	$	446,735	$	106	$	(257	)	$	446,584

The $3 thousand difference between the net unrealized loss reflected in the above table and that per the statement of comprehensive income is due to unrealized losses relating to debt securities which were cash equivalents as of December 31, 2022, and are therefore not included in the table above.

The following table presents the amortized cost and fair value of the Company's fixed income securities by maturity grouping:


	December 31, 2022
(in thousands)	Amortized cost		Fair value
Due in one year or less	$	328,405	$	328,359
Due after one year through five years		118,330		118,225
Due after five years through ten years		-		—
Due after ten years		-		—
Total	$	446,735	$	446,584

There were no securities which were determined to be other-than-temporarily impaired as of the year ended December 31, 2022. There were no sales of securities which resulted in a realized loss during the year ended December 31, 2022. The Company recognized $9.6 million of interest income earned from its available-for-sale debt securities and money market funds. The Company also recognized $1.8 million of accretion on its available-for-sale debt securities, which was recorded to interest income.
