[1] The maturities of long-term marketable securities range from one to four years.

[2] Restricted cash is included in other noncurrent assets and primarily represents balances related to the MMJ Creditor Payments and interest reserve balances related to the 2021 MSTW Term Loan.

[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 analyses to validate information obtained from these pricing services. No adjustments were made to the fair values indicated by such pricing information as of March 1, 2018 or August 31, 2017.
