My Lords, I, too, am worried about these words. I shall not repeat what the noble Lord, Lord Tunnicliffe, has said. It is really a question about what are allowable costs. As anybody in business knows, allowable costs can be described in so many ways. For instance, Starbucks does not pay any tax in this country because it charges its royalties from overseas against its costs in this country. Would that on a contract for a submarine be allowable costs? If the contractor is producing, let us say, one submarine, can it therefore charge all of its chairman’s, managing director’s and executive board’s salaries against the cost of that one submarine? If it is also producing a group of battleships or carriers, those executive costs, for example, would be spread over all the costs of all those items of equipment.
In her previous reply, the Minister spoke about an audit trail. The noble Lord, Lord Tunnicliffe, used the word “reasonable” and all the other adjectives. A contractor who wished to drive a coach and horses through this could do so by manipulating what could be administrative costs. It is very easy to say that if the mythical submarine requires a widget, that widget is applicable to that submarine. You can see that, but when you are dealing with, let us say, the premises for the submarine, if it is one submarine, is the contractor allowed to charge the whole of the premises costs against the cost of that submarine? If it was also building an aircraft carrier, it could charge some of that premises costs against it. I invite the Minister to come back, perhaps on Report, with some better reassurance about how allowable costs will be allocated and particularly about how to spread large costs if only one item of equipment is produced by that contractor.
