We perform an analysis of goodwill on an annual basis. We last performed this analysis as of October 30, 2011. The result of that analysis indicated that no goodwill impairment existed as of that date. We are presently in the process of completing this annual analysis based on the goodwill amount as of the first business day of our third quarter. We face a number of risks to our business which can adversely impact cash flows in each of our business units and cause a significant decline in the fair values of each business unit. This decline could lead to an impairment of goodwill in some or all of our business units. Certain events, such as a worsening trend of orders and sales without a corresponding way to preserve future cash flows or a significant decline in our stock price, could cause a further impairment in goodwill.
