8. COMMITMENTS AND CONTINGENCIES

Product Warranties

The Company generally provides either a one- or two-year warranty against defects in materials and workmanship and will repair the products, provide replacements at no charge to customers or issue a refund. As they are considered assurance-type warranties, the Company does not account for them as separate performance obligations. Warranty reserve requirements are mainly based on a specific assessment when a customer asserts a claim for warranty or a product defect.

The changes in warranty reserves are as follows (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,
	2023			2022			2023			2022
Balance at beginning of period	$	19,726		$	23,833		$	24,082		$	20,989
Warranties issued		580			475			942			475
Repairs, replacements and refunds		(1,581	)		(139	)		(2,253	)		(1,519	)
Changes in liability for pre-existing warranties		(1,071	)		1,040			(5,117	)		5,264
Balance at end of period	$	17,654		$	25,209		$	17,654		$	25,209

Changes in liability for pre-existing warranties result from changes in estimates for warranties issued in prior periods.

Purchase Commitments

The Company has outstanding purchase obligations with its suppliers and other parties that require the future purchases of goods or services. The purchase obligations primarily consist of wafer and other inventory purchases, assembly and other manufacturing services, construction of manufacturing and research and development facilities, purchases of production and other equipment, and license arrangements.

In May 2022, the Company entered into a long-term supply agreement in order to secure manufacturing production capacity for silicon wafers over a four-year period. As of June 30, 2023, the Company had made prepayments under this agreement of $170.0 million, of which $50.0 million was classified as short-term.

Total estimated future unconditional purchase commitments to all suppliers and other parties as of June 30, 2023 were as follows (in thousands):

2023 (remaining six months)	$	160,296
2024		297,556
2025		293,702
Total	$	751,554

Litigation

The Company is a party to actions and proceedings in the ordinary course of business, including challenges to the enforceability or validity of its intellectual property, claims that the Company’s products infringe on the intellectual property rights of others, and employment matters. The Company may also be subject to litigation initiated by its stockholders. These proceedings often involve complex questions of fact and law and may require the expenditure of significant funds and the diversion of other resources to prosecute and defend. The Company defends itself vigorously against any such claims. As of June 30, 2023, there were no material pending legal proceedings to which the Company was a party.
