On December 30, 2006, you buy a Ford Expedition. It comes with a three-year, 36,000-mile warranty. On January 18, 2007, you return the Expedition to the dealership for some basic repairs covered under the warranty. The cost of the repairs to the dealership is $725. In what year, 2006 or 2007, should Ford Motor Co. recognize the cost of the warranty repairs as an expense?
