FAIR VALUE

The carrying amounts for many of our financial instruments, including cash and cash equivalents, accounts and notes receivable, accounts and notes payable, short-term borrowings and certain other liabilities, approximate their fair value due to their relatively short maturities. Our short-term investments, foreign exchange forward contracts and long-term investments are measured at fair value on the Condensed Consolidated Balance Sheets.

Our total debt is carried at cost and was $295.6 and $297.4 as of November 24, 2017 and February 24, 2017, respectively. The fair value of our total debt is measured using a discounted cash flow analysis based on current market interest rates for similar types of instruments and was approximately $325 and $330 as of November 24, 2017 and February 24, 2017, respectively. The estimation of the fair value of our total debt is based on Level 2 fair value measurements.

We periodically use derivative financial instruments to manage exposures to movements in foreign exchange rates and interest rates. The use of these financial instruments modifies the exposure of these risks with the intention to reduce our risk of short-term volatility. We do not use derivatives for speculative or trading purposes.

Assets and liabilities measured at fair value in our Consolidated Balance Sheets as of November 24, 2017 and February 24, 2017 are summarized below:
