British Telecommunications Plc’s year-end 10K filing to the US Securities & Exchange Commission paints a downbeat picture of how regulatory controls could affect its future performance, the Sunday Times reported: Competition will continue to increase in all major areas of BT’s business, and this is likely to result in further erosion of its market share, including in some of its more profitable operations, the company is quoted as saying, and that new price controls by the Office of Telecommunications, which take effect on August 1 will significantly curtail its ability to vary prices, and that the entrance of international rivals into the UK market is likely to reduce BT’s market share and revenue, especially as its ability to compete with the cable television and cellular phone companies is very restricted.
