(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 August 29, 2019 or August 30, 2018.
(4) | Restricted cash is included in other noncurrent assets and primarily relates to the MMJ Creditor Payments and government incentives received prior to being earned. The restrictions lapse on the MMJ Creditor Payments upon approval by the trustees and/or Tokyo District Court and for the government incentives upon achieving certain performance conditions.
Gross realized gains and losses from sales of available-for-sale securities were not material for any period presented. As of August 29, 2019, there were no available-for-sale securities that had been in a loss position for longer than 12 months.
