[1] Long-term debt includes the current portion ($4,540 and $4,095 as of June 30, 2013 and 2012, respectively) of debt instruments. Long-term debt is not recorded at fair value on a recurring basis, but is measured at fair value for disclosure purposes. Fair values are generally estimated based on quoted market prices for identical or similar instruments.

[2] Investment securities and all derivative assets are presented in prepaid expenses and other current assets and other noncurrent assets. The amortized cost of the U.S. government securities was $1,604 as of June 30, 2013. All U.S. government securities have contractual maturities between one and five years. Fair values are generally estimated based upon quoted market prices for similar instruments.

[3] All liabilities are presented in accrued and other liabilities or other noncurrent liabilities.

[4] Other foreign currency instruments are comprised of foreign currency financial instruments that do not qualify as hedges.
