Goodwill is annually tested for impairment to determine whether the carrying value of the goodwill exceeds its fair value. When this happens then goodwill impairment is charged. It should be noted that goodwill is recorded after acquisition of assets and liabilities and the price paid for them is greater than the identifiable value. Annual testing enables to determine any deterioration in the power of the assets that have been acquired to generate cash flows. When this happens then the fair value of the goodwill falls below its book value.
