§ Miss Quennell
asked the Secretary of State for Trade and Industry how many nationalised industries, State boards and undertakings of whatever nature calculate their profits on a 10 per cent. per annum compound basis; and if he will list them.
§ Mr. Emery
If my hon. Friend is referring to the use of a minmum test discount rate of 10 per cent. in assessing the return on capital expenditure, this practice is followed by all the nationalised boards for which my right hon. Friend is responsible, i.e. the British Airports Authority, the British Airways Board, the British Steel Corporation, the Electricity 159W and Gas Boards, and the National Coal Board.
