Impairment exists when a reporting unit's carrying value of goodwill exceeds its fair value, which is determined through a two-step impairment test.  Step one includes the determination of the carrying value of the reporting unit, including the existing goodwill and intangible assets, and estimating the fair value of the reporting unit.  If the carrying amount of a reporting unit exceeds its fair value, we are required to perform a second step to the impairment test.  The Corporation performed Step one of the two-step impairment test and determined that goodwill was not impaired.
