Exercise 10-10 Identifying upstream and downstream costs LO 10-4 During 2017, Thornton Manufacturing Company incurred $75,200,000 of research and development (R&D) costs to create a long-life battery to use in computers. In accordance with FASB standards, the entire R&D cost was recognized as an expense in 2017. Manufacturing costs (direct materials, direct labor, and overhead) are expected to be $50 per unit. Packaging, shipping, and sales commissions are expected to be $11 per unit. Thornton expects to sell 1,600,000 batteries before new research renders the battery design technologically obsolete. During 2017, Thornton made 443,000 batteries and sold 396,000 of them. Required Identify the upstream and downstream costs.
