Goodwill and Intangible Assets Disclosure [Text Block] | 14. Goodwill and Goodwill Impairment The Company’s policy is to assess goodwill for impairment at the reporting unit level on an annual basis or between annual assessments if a triggering event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Impairment is the condition that exists when the carrying amount of goodwill exceeds its implied fair value.
