| Schedule of Methodologies Used to Estimate Fair Value |
The methodologies used to estimate fair value are as follows: | | | | | | | Components | Methodology used to estimate fair value | | Debt securities classified as available-for-sale | Quoted market prices for identical instruments | | Foreign exchange forward contracts, currency options and collars | Quoted market prices for similar instruments | | Equity securities measured at fair value through earnings | Quoted market prices for identical instruments | | Equity securities carried at cost as a measurement alternative | Valuation of the underlying investments on a new round of third-party financing or upon liquidation | | Long-term debt and current portion of long-term debt | Future cash flows on a borrowing-by-borrowing basis and discounting these future cash flows using the Company's incremental borrowing rates for similar types of borrowing arrangements. For convertible bonds, the fair value represents the market price of the bonds trading on the Frankfurt Stock Exchange | | Cash and cash equivalents, short-term deposits, accounts receivable, short-term borrowings, and accounts payable | The carrying amounts reflected in the consolidated financial statements are considered as reasonable estimates of fair value due to the relatively short period of time between the origination of the instruments and their expected realization. |
