[1] | Cash equivalents are comprised of certificates of deposit, time deposits and other interest-bearing investments with original maturity dates of 90 days or less. Cash equivalents are recorded at cost, which approximates fair value. |
[2] | Time deposits are comprised of deposits with original maturities of more than 90 days but less than one year and instruments with original maturities of greater than one year, included in other current assets or other assets in the Consolidated Balance Sheet, as appropriate. Time deposits are recorded at cost, which approximates fair value. |
[3] | Short-term debt is comprised of U.S. commercial paper and other similar short-term debt issued by non-U.S. subsidiaries, all of which are recorded at cost, which approximates fair value. |
[4] | Long-term debt includes the current portion of these debt instruments and excludes the monetization loan. Fair values were estimated based on quoted prices for financial instruments for which all significant inputs were observable, either directly or indirectly. |
[5] | The note, monetization loan and redeemable preferred securities of subsidiary are not traded in active markets. Accordingly, their fair values were calculated using a floating rate pricing model that compared the stated spread to the fair value spread to determine the price at which each of the financial instruments should trade. The model used the following inputs to calculate fair values: face value, current LIBOR rate, unobservable fair value credit spread, stated spread, maturity date and interest payment dates. |
[6] | The fair value of the redeemable common securities of subsidiary was based on various inputs, including an independent third-party appraisal, adjusted for current market conditions. |
