[1] The maturities of long-term marketable securities range from one to four years.
[2] Restricted cash is included in other noncurrent assets and generally represents balances related to the MMJ Creditor Payments and interest reserve balances related to the 2021 MSTW Term Loan. The restrictions on the MMJ Creditor Payments lapse upon approval by the trustees and/or Japan Court. The restrictions on the interest reserve balances lapse in proportion to the reduction in the amount of interest expected to be paid under the 2021 MSTW Term Loan for the subsequent six months. (See "Debt" note.)
[3] The fair value of Level 1 securities is measured based on quoted prices in active markets for identical assets.
[4] 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 such pricing information as of August 31, 2017 or September 1, 2016.
