In connection with the acquisition of certain product right assets related to the Kristalose brand as discussed in Note 7, the Company is responsible for purchasing the active pharmaceutical ingredient for Kristalose and maintains this raw material inventory at its third-party manufacturer. As the ingredients are consumed in production, the value of the ingredients is transferred from raw materials to finished goods.
