(1)The maturities of long-term marketable securities primarily range from one to four years.
(2)The fair value of Level 1 securities is measured based on quoted prices in active markets for identical assets.
(3)The fair value of Level 2 securities is measured using information obtained from pricing services, which obtain quoted market prices for similar instruments, non-binding market consensus prices that are corroborated by observable market data, or various other methodologies, to determine the appropriate value at the measurement date. We perform supplemental analysis to validate information obtained from these pricing services. No adjustments were made to the fair values indicated by such pricing information as of June 2, 2022 or September 2, 2021.
(4)Restricted cash is included in other current assets and other noncurrent assets and primarily relates to certain government incentives received prior to being earned and for which restrictions lapse upon achieving certain performance conditions.

Gross realized gains and losses from sales of available-for-sale securities were not significant for any period presented.

In addition to the amounts included in the table above, we had $210 million and $153 million of non-marketable equity investments without a readily determinable fair value that were included in other noncurrent assets as of June 2, 2022 and September 2, 2021, respectively.
