 The resulting organisation, Openreach, opened for business in January 2006 and reported directly to the BT chief executive.The functional separation of Openreach from BT has had mixed results, according to economists J. Gregory Sidak and Andrew Vassallo, who have argued that while Openreach’s creation produced the short-run benefit of lower prices, it also led to long-run costs, such as declines in telecommunications investment, customer satisfaction, and measures of the United Kingdom’s global competitiveness in telecommunications.Today, the company is structured such that it is a wholly owned subsidiary of British Telecommunications plc (BT), which itself includes the four separately managed businesses and virtually all other assets of the BT Group.
