[1] The fair value amount is presented as of the date of impairment, as these assets are not measured at fair value on a recurring basis. See also Note 1E. Basis of Presentation and Significant Accounting Policies: Fair Value.

[2] Reflects intangible assets written down to their fair value in 2013. Fair value was determined using the income approach, specifically the multi-period excess earnings method, also known as the discounted cash flow method. We started with a forecast of all the expected net cash flows associated with the asset and then we applied an asset-specific discount rate to arrive at a net present value amount. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of competitive, legal and/or regulatory forces on the product and the impact of technological risk associated with IPR&D assets; the discount rate, which seeks to reflect the various risks inherent in the projected cash flows; and the tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.
