(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 30, 2018 or August 31, 2017.
(4) | Restricted cash is included in other noncurrent assets and included balances related to the MMJ Creditor Payments. The restrictions on the MMJ Creditor Payments lapse upon approval by the trustees and/or Tokyo District Court. Restricted cash as of August 31, 2017 also included interest reserve balances related to our 2021 MSTW Term Loan, which were released in 2018 in connection with our prepayment of the 2021 MSTW Term Loan. (See "Debt" note.)
