Methodology:
We attempted to include as many companies across the broad universe of the U.S. retail industry as possible, deriving information from sources including company press releases and presentations, conference calls and SEC filings. In cases where information was not explicitly provided by the company, RetailSails used estimates based on industry sources or competitors' figures. We attempted to strip out all non-store retail related revenue, such as direct-to consumer (e-commerce, catalog & phone) sales, wholesale, franchise and licensing revenue, membership fees, financial services revenue and gasoline sales, in order to normalize data to provide a meaningful and comprehensive apples-to-apples comparison of retail store productivity.
