Impairment tests for goodwill

Goodwill is not subject to amortization and is tested annually for impairment (normally at the end of the third fiscal quarter) or more frequently if events or changes in circumstances indicate a potential impairment. Management has considered the carrying amount of goodwill as of 31 December 2019 and concluded that, as there are no indicators of impairment, a detailed impairment test is not required. Having assessed the future anticipated cash flows, management believes that any reasonably possible changes in key assumptions would not result in an impairment of goodwill.
