Goodwill is tested for impairment annually (as
at December 31) and when circumstances
indicate that the carrying value may be
impaired. Impairment is determined for
goodwill by assessing the recoverable amount
of each CGU (or group of CGUs) to which the
goodwill relates. Where the recoverable
amount of the CGU is less than its carrying
amount, an impairment loss is recognized.
