[1] (1) These identifiable intangible assets are being amortized under the income forecast method, which assumes the value derived from these intangible assets is greater in the earlier years and steadily declines over time.

[2] The excess reorganization value over the fair value of identified tangible and intangible assets of $2.1 billion was recorded as goodwill. See “Enterprise Value / Reorganization Value Determination” below for additional information.

[3] We recognized a goodwill impairment charge of $801.1 million during the three months ended June 30, 2011. See Note 2, “Summary of Significant Accounting Policies – Identifiable Intangible Assets and Goodwill” for further discussion.
