Brands and trademarks consist of intellectual property purchased from Sun 8 Holdings Inc. with a useful life of 15 years and other intellectual property with a useful life of 12 years.

Patents consisted of intellectual property acquired through the acquisition of Pathway Rx Inc. which consisted of proprietary rights to certain technology, copyrights and trademarks with a useful life of 20 years. During the year ended December 31, 2020, the Company determined that indicators of impairment existed regarding the Pathway intellectual property due to the Company’s decision to reduce its focus on medical cannabis research. The estimated recoverable amount of the intangible assets was determined to be their fair value less costs of disposal and an impairment of $12.9 million was recorded to write down the assets to their recoverable amount of nil.

Brands and trademarks consisting of intellectual property acquired as part of the Bridge Farm acquisition, customer relationships and other intangible assets consisting of non-compete clauses and energy credits were disposed of as part of the sale of Bridge Farm (note 5).
