Solution to previous puzzler: FORTUNE 1000

To recap: The following words are all derived in some uniform way from the names of Fortune 1000 companies. What is the rule and what are the companies? The disguised words are: Lean, Lover, Lord, Less, Lost, Like, Loss, Lush, Loll, Lest. Solution: Each word substitutes the initial letter L for the real initial letter of the first word of the company name. For example, “Ford” is disguised as “Lord.” The words are listed in alphabetical order by name of company: Lean=Dean (Foods), Lover=Dover, Lord=Ford, Less=Hess, Lost=Host (Hotels & Resorts), Like=Nike, Loss=Ross (Stores), Lush=Rush, Loll=Toll, Lest=West.
