The statement below shows the time allowances and the average actual times under the departmental heads used in the financial accounts. The average actual times are obtained using the latest bonus earnings and where possible we have taken chassis sections only, but where departments are producing both chassis and aero work, viz: Automatics, Gear Cutters etc. we have, of necessity, had to apply the bonus earnings for both products.
