5.19 Computing and Interpreting Bankruptcy Prediction Ratios. Exhibit 5.21 presents selected financial data for Best Buy Co., Inc., and Circuit City Stores, Inc., for fiscal 2008 and 2007. Best Buy and Circuit City operate as specialty retailers offering a wide range of consumer electronics, service contracts, product repairs, and home installation. Competition from Walmart, Costco, and Internet retailers put downward pressure on prices and margins. In November 2008, Circuit City filed Chapter 7 bankruptcy. In the media, Circuit City's bankruptcy was largely blamed on its poor treatment of employees. In early 2007, Circuit City laid off 3,400 high-paid salespersons, or approximately 8% of its workforce, which left inexperienced, low-paid workers in charge of customer service. Customer service quality plummeted, which was especially harmful for a retail business providing expensive electronic items, warranty products, and installation services. REQUIRED a.
