The following methods and assumptions were used in estimating fair values: Cash and cash equivalents: Due to the liquid nature of these instruments, the carrying amount approximates fair value (Level 1). Credit facility - multicurrency revolving line of credit: The revolver is not traded publicly. The fair values, which are determined based upon a hypothetical market participant, are calculated using a discounted cash flow model with Level 2 inputs, including estimates of incremental borrowing rates for debt with similar terms, maturities, and credit profiles. Refer to Note 6: Debt for a further discussion of our debt. Convertible notes: The convertible notes are not listed on any securities exchange but may be actively traded. The fair value is estimated using Level 1 inputs, as it is based on quoted prices for these instruments in active markets. Derivatives: Each derivative asset and liability has a carrying value equal to fair value. The fair values of our derivative instruments are determined using the income approach and significant other observable inputs (and are classified as "Level 2" in the fair value hierarchy). We have used observable market inputs based on the type of derivative and the nature of the underlying instrument. The key inputs include foreign exchange spot and forward rates, all of which are available in an active market. We have utilized the mid-market pricing convention for these inputs.
