Assets Held for Sale [Abstract] |
Assets Held for Sale | Note 4. Assets Held for Sale Assets held for sale of $2.4 million and $1.9 million as of December 28, 2011 and December 29, 2010, respectively, included restaurants to be sold to franchisees. Our Credit Facility (defined in Note 11) requires us to make mandatory prepayments to reduce outstanding indebtedness with the net cash proceeds from the sale of restaurant assets and restaurant operations to franchisees, net of a voluntary $25.0 million annual exclusion. As of December 28, 2011 and December 29, 2010, no reclassification of long-term debt to current liabilities was required. As a result of classifying certain assets as held for sale, we recognized impairment charges of $0.8 million, $0.1 million and $0.4 million for the years ended December 28, 2011, December 29, 2010 and December 30, 2009, respectively. This expense is included as a component of operating (gains), losses and other charges, net in our Consolidated Statements of Income.
