(1)The maturities of long-term marketable securities 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 December 3, 2020 or September 3, 2020. (4)Restricted cash is included in 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.
