Distributor businesses

The recoverable amount of goodwill with distributor businesses has been determined based on a “value in use” calculation. This calculation uses cash flow projections based on an extrapolation of the year end cash flows and available budget information, over 10 years. The cash flows have been discounted using the pre-tax discount rate of 14.6% p.a. No growth rate has been factored in. Management believes that any reasonably possible change in the key assumptions on which the recoverable amount is based would not cause the carrying amount of goodwill recorded to exceed its recoverable amount.

Key assumptions used in “value in use” calculations

Key assumption
Basis for determining value in use assigned to key assumption
Gross profitEarnings before interest, tax, depreciation and amortisation (EBITDA)
Estimated long-term average growth rate No forecasted growth
Discount periodRepresents expected payback period of acquisitions
