⁽¹⁾During the fourth quarter of 2017, we identified impairment indicators in our Octane Fitness brand name originally acquired through the Octane Fitness acquisition on December 31, 2015. Ongoing weakness in the specialty retail channel, as a result of retailer consolidation, has had a negative impact on Octane branded sales and projected growth trends. We utilized the relief-from-royalty method to quantify the impairment, resulting in an $8.8 million non-cash impairment charge for 2017.
