A firm considers to buy a machine in 2021. The cost of the machine is $ 3 000 000 which will be paid in 2021. The economic lifetime of the machine is 5 years (the machine will generate cashflows for the firm starting in 2022). The firm estimates that the new machine will increase the sales revenue of the firm by $ 1 500 000 in each of the next 5 years. The COGS is estimated to be 40% of the sales revenue. The general and administrative costs are estimated to be 10% of the sales revenue. The firm uses 5-year straight line depreciation and is allowed to write off $ 600 000 depreciation expense in each of the next 5 years. The firm is subject to a 20% tax rate. The firm also estimates that the new machine will lead to a $ 50 000 increase in inventories, $ 70 000 increase in accounts receivables and $ 20 000 increase in accounts payables receivables in 2022. There will be no change in NOWC (net operating working capital) in 2023 and 2024.
