ROCE based on controllable operating profit

Hi sir, I want to ask about the divisional performance measurement.

1. May I knw do we need to include fixed costs in calculating controllable operating profit (ignoring allocated cost)???? If no need, is that means straight away use the contribution figure as controllable operating profit?
2. Do we include non-cash items in calculating controllable operating profit?

ABC Ltd has two divisions that produce electrical products and the following information are extracted from financial statements of those divisions. Management are concerned about the poor performance of Division B when comparing ROCE. There has been considerable investment in PPE for Division B. However, NCA in division A are much more older. Depreciation for PPE is included in divisional fixed production costs. The company expects a return of 10% on investment made so it has expressed a concern that the division B is not performing well
