After the Separation, our reporting units consisted of mortgage origination services, default and technology services, specialty finance solutions, risk and fraud analytics, employer services, litigation services and marketing services. After the sale of the employer and litigation services businesses, our reporting units, for purposes of applying the provisions of accounting guidance related to goodwill, are risk and fraud analytics, specialty finance solutions, mortgage origination services, default and technology services and marketing services.

During the six months ended June 30, 2011, we recorded $18.9 million of goodwill in connection with our acquisition of the remaining interest in Dorado in March 2011 and we recorded $162.9 million of goodwill in connection with our acquisition of the remaining interest in RP Data on May 2011.

In accordance with accounting guidance and consistent with prior year practice, our policy is to perform an annual goodwill impairment test for each reporting unit in the fourth quarter (using the September 30 valuation date), unless there is a triggering event. We have not performed an impairment analysis on any of our reporting units during the six months ended June 30, 2011, as no triggering events requiring such an analysis have occurred.

As of the date of our 2010 annual impairment review, the marketing services reporting unit included $123.3 million of goodwill. The fair value of this reporting unit under the income value approach was below the carrying value of the reporting unit's book value by approximately 10% and the fair value under the market value approach exceeded the reporting unit's book value by 11%. In assessing the realizability of goodwill, management considered the results of both analyses and weighed them accordingly given market conditions and expectations. Determining the fair value of a reporting unit is judgmental in nature and requires the use of significant estimates and assumptions, including revenue growth rates and operating margins, discount rates and future market conditions, among others. Key assumptions used to determine the fair value of the marketing services reporting unit in our 2010 annual testing were: (a) expected cash flow for the period from 2011 to 2019; (b) a discount rate of 18.5%, which was based on management's best estimate of the after-tax weighted average cost of capital; and (c) a 25% control premium. It is reasonably possible that changes in the facts, judgments, assumptions and estimates used in assessing the fair value of the goodwill of the marketing services reporting unit could cause this or other reporting units to become impaired. There were no other reporting units that management deemed to have a reasonable risk of material impairment charge at the time.
