In December 2020, BellRing finalized its plan to discontinue the Supreme Protein brand and related sales of Supreme Protein products. In connection with the discontinuance, BellRing updated the useful lives of the customer relationships and trademarks associated with the Supreme Protein brand to reflect the remaining period in which BellRing expects to continue to sell existing Supreme Protein product inventory. The net carrying values of the customer relationships and trademarks associated with the Supreme Protein brand were $18.7 and $11.8 as of December 31, 2020, respectively, which are expected to be fully amortized by June 1, 2021 as a result of their updated useful lives.
