At the end of 2019, Sapporo Group tests a machine for impairment. The machine is carried at depreciated historical cost, and its carrying amount is ¥150,000. It has an estimated remaining useful life of 10 years. The machine's recoverable amount is determined on the basis of a value-in-use calculation, using a pretax discount rate of 15%. Management-approved budgets reflect estimated costs necessary to maintain the level of economic benefit expected to arise from the machine in its current condition. The following information related to future cash flows is available at the end of 2019 (amounts in thousands).
