[1] During the year ended December 31, 2021, the Company estimated an overall decrease in the sales forecast for AW products, due to an inventory item rationalization, in addition to a decrease in the sales forecast of ISI seeds, related to the saturated hemp seed market. As a result, Arcadia performed a quantitative intangible assets impairment test. The Company used a discounted cash flow approach to develop the fair value of our acquired intellectual property, customer lists, brands and trademarks. As a result of this assessment, Arcadia recorded an impairment of intangible assets in the amount of $3.3 million in the consolidated statements of operations and comprehensive loss for the year ended December 31, 2021.
