Amortization Expense related to other intangible assets was $6 million for each of the years ended December 31, 2012, 2011, and 2010. Lease interest amortization is recorded as rent expense in plant operating expenses and was $3 million for each of the years ended December 31, 2012, 2011, and 2010.
Goodwill
Goodwill represents the total consideration paid in excess of the fair value of the net tangible and identifiable intangible assets acquired and the liabilities assumed in acquisitions. Goodwill has an indefinite life and is not amortized but is reviewed for impairment under the provisions of accounting standards for goodwill. We performed the required annual impairment review of our recorded goodwill for our reporting unit using a quantitative and qualitative assessment as of October 1, 2012 and determined that it was more likely than not that the fair value of our reporting unit was not less than its carrying value and no further assessment was necessary. As of December 31, 2012, goodwill of approximately $38 million was deductible for federal income tax purposes.
