Risks and Uncertainties
At January 28, 2011, we had intangible assets totaling $40.9&amp;#160;million on our consolidated balance sheet related to our acquisition of Mimi&amp;#8217;s Caf&amp;#233;.&amp;#160; Specifically, this amount includes $34.0 million for the unamortized Mimi&amp;#8217;s Caf&amp;#233; trade name and $6.9 million for the Mimi&amp;#8217;s Caf&amp;#233; restaurant concept, which is amortized over a 15-year life. &amp;#160;We are required to perform annual impairment tests of our intangible assets (or more frequently if events or changes in circumstances indicate the asset might be impaired), which we perform in the fourth quarter of the fiscal year. Impairment testing of the Mimi&amp;#8217;s Caf&amp;#233; trade name requires that we determine its fair value.  If the fair value of the asset is less than its $34.0 million carrying value, an impairment charge would be recognized in an amount equal to the difference.  The impairment test for the $6.9 million restaurant concept asset involves a three-step process, whereby we first consider whether indicators of impairment are present.  If indicators are present, the second step is to compare the sum of the undiscounted future cash flows attributable to the asset to its carrying value.  In the event that the undiscounted cash flows are less than the carrying value, the third step is to determine the fair value of the restaurant concept.  If the fair value is less than its carrying value, an impairment charge would be recognized for the difference.  We use the relief-from-royalty method, which is an income approach to valuation, to determine the fair values of the trade name and restaurant concept intangible assets.  Using the relief-from-royalty method, the fair values are impacted by projected sales, including plans for new restaurant development and same-store sales trends.
In the fourth quarter of fiscal 2010, we completed our annual impairment tests of intangible assets. &amp;#160;The assumptions we used for projected sales were based on our current five-year development and financial forecasts for Mimi&amp;#8217;s Caf&amp;#233;. &amp;#160;Using these assumptions, the fair values of the Mimi&amp;#8217;s Caf&amp;#233; trade name and restaurant concept exceeded their carrying values, and as a result, no impairment charges were recorded. &amp;#160;&amp;#160;Although we believe our current plans and forecasts to be achievable, there is the potential that our actual future results could differ from these forecasts, especially given Mimi&amp;#8217;s Caf&amp;#233;&amp;#8217;s prolonged negative same-store sales trend.  No impairment indicators were identified related to the Mimi&amp;#8217;s Caf&amp;#233; trade name or restaurant concept in the third quarter of fiscal 2011.  If Mimi&amp;#8217;s Caf&amp;#233;&amp;#8217;s performance falls below expectations in future periods, impairment charges related to the Mimi&amp;#8217;s Caf&amp;#233; trade name and restaurant concept could arise. &amp;#160;</NonNumbericText><NonNumericTextHeader>9.
