https://en.wikipedia.org/wiki/Asda
"Asda Stores Limited is an American-owned, British-founded supermarket retailer, headquartered in Leeds, West Yorkshire.[3] The company became a subsidiary of the American retail corporate giant Walmart after a £6.7 billion takeover in July 1999, and is now the second-largest supermarket chain in Britain, by market share.[4]
Besides its core supermarket retail format, the company also offers a number of other products, including financial services and a mobile phone company using the existing network of EE. Asda's marketing promotions are usually based solely on price, and like its parent company, Walmart, Asda promotes itself under the slogan "Save Money. Live Better".[5]
As a wholly owned division of Walmart, Asda is not required to declare quarterly or half-yearly earnings, but it submits full accounts to the U.S. Securities and Exchange Commission each November."
