Management Accounting and Business Finance

What the exam tests

This domain tests decision support: cost behaviour and relevant costing, budgeting and variance analysis, short-term decisions, and long-term investment appraisal using NPV, IRR and payback. Business finance extends this to the cost of capital, gearing and working capital management - examined in a Malawian context of high borrowing costs, kwacha volatility and foreign-exchange scarcity.

Core rules

  • Relevant costs are future, incremental cash flows. Sunk costs, committed costs and apportioned fixed overheads are excluded; opportunity costs are included even though no cash leaves the business.
  • CVP analysis: contribution per unit = selling price − variable cost; break-even units = fixed costs ÷ contribution per unit. Use contribution, not profit, for short-term decisions with spare capacity.
  • NPV discounts incremental after-tax cash flows at the WACC, includes working capital investment and its recovery, and ignores financing cash flows because the discount rate already captures them.
  • WACC uses market values and after-tax cost of debt: WACC = (E/V × Ke) + (D/V × Kd × (1 − t)).
  • Working capital: shortening the cash cycle releases cash - relevant where forex and kwacha liquidity are constrained.

Worked example: WACC

Market value of equity K900m, market value of debt K600m, so V = K1,500m. Cost of equity 18%, pre-tax cost of debt 14%, corporate tax 30%.

Weights: equity 60%, debt 40%. After-tax cost of debt = 14% × 0.70 = 9.8%. WACC = (0.60 × 18%) + (0.40 × 9.8%) = 10.8% + 3.92% = 14.72%. This is the rate to discount a project of comparable business risk; using the pre-tax 14% would overstate the discount rate and understate NPV by ignoring the tax shield on interest.

Traps that cost marks

  • Using book values instead of market values for the WACC weights.
  • Discounting accounting profit rather than cash flow, or omitting working capital recovery at the end of the project.
  • Including sunk research costs in a relevant-costing decision.
  • Choosing the highest IRR project when projects differ in size or life - use NPV for value maximisation.
