[1] The re-engineering and impairment charges line provides for severance and other exit costs. See Note 2 to the Consolidated Financial Statements.

[2] Reviews of the value of the intangible assets related to the acquisition of the Sara Lee Direct Selling units acquired in 2005 resulted in the conclusion that certain of the tradenames and goodwill had been impaired. This resulted in 2011 charges of $36.1 million related to Nutrimetics, and in 2009, in charges of $28.1 million related to Nutrimetics, NaturCare and Avroy Shlain. In 2010, the Company recorded an impairment of $4.3 million related to Swissgarde in connection with a decision to cease operating that unit as a separate business. See Note 6 to the Consolidated Financial Statements.
