Asda Stores Ltd (often referred to as Asda, Asda's or Asda Price) is a British supermarket chain which retails food, clothing, general merchandise, toys and financial services. It also has a mobile telephone network, (via the Vodafone Network), Asda Mobile. Its head office is at Asda House in Leeds, West Yorkshire.
Asda became a subsidiary of the American retail giant Walmart, the world’s largest retailer, in 1999, and is the UK's second largest chain by market share after Tesco. In December 2010, Asda's share of the UK grocery market stood at 16.5%.
Asda's marketing promotions have usually been based solely on price, with Asda promoting itself under the slogan Britain's Lowest Priced Supermarket, 14 Years Running. As a wholly owned division of Wal-Mart, Asda is not required to declare quarterly or half-yearly earnings. It submits full accounts to Companies House each October.
