Goodwill is tested for impairment on an annual basis, as of December 31, and between annual tests whenever events or circumstances indicate that the carrying value of a reporting unit may not exceed its fair value. No such events or circumstances occurred during the three months ended September 30, 2011.

Intangible assets are amortized on the straight-line method over their legal or estimated useful lives. The following summarizes the gross carrying value and accumulated amortization for each major category of intangible assets:

No such events or circumstances occurred during the three months ended September 30, 2011.
