Goodwill and Intangible Assets, Policy	Goodwill carrying amounts are evaluated for impairment, at least annually on December 31 each year, at the reporting unit level that is equivalent to an operating segment. If the fair value of a reporting unit is less than its carrying amount, further evaluation is required to determine if a write-down of goodwill is required. In determining the fair value of each reporting unit, we used an income approach, applying a discounted cash flow method that included a residual value. Based on historical experience, we make assumptions as to: (i) expected future performance and future economic conditions, (ii) projected operating earnings, (iii) projected new and renewal business as well as profit margins on such business, and (iv) a discount rate that incorporated an appropriate risk level for the reporting unit. Any impairment of goodwill would be charged to expense. Other intangible assets are amortized to expense over their estimated useful lives and are subject to impairment testing. Any impairment of other intangible assets would be charged to expense.
