Accounting policy
Goodwill is not amortised but is reviewed for impairment annually. Goodwill is allocated to the cash-generating unit (CGU) that is expected to benefit from the acquisition. The goodwill is tested annually for impairment by comparing the recoverable amount to the carrying value of the CGUs. The CGUs identified by management are at the aggregated product franchise levels of Orthopaedics, Other Surgical Devices and Advanced Wound Management, in the way the core assets are used to generate cash flows.
If the recoverable amount of the CGU is less than its carrying amount then an impairment loss is determined to have occurred. Any impairment losses that arise are recognised immediately in the income statement and are allocated first to reduce the carrying amount of goodwill and then to the carrying amounts of the other assets of the CGU.
In carrying out impairment reviews of goodwill a number of significant assumptions have to be made when preparing cash flow projections. These include the future rate of market growth, discount rates, the market demand for the products acquired, the future profitability of acquired businesses or products, levels of reimbursement and success in obtaining regulatory approvals. If actual results should differ, or changes in expectations arise, impairment charges may be required which would adversely impact operating results.
