Billingham Packaging is considering expanding its production capacity by purchasing a new machine, the XC-750. The cost of the XC-750 is S2.74 million. Unfortunately installing this machine will take several months and will partially disrupt production. The firm has just completed a $49,000 feasibility study to analyze the decision to buy the XC-750, resulting in the following estimates: Marketing: Once the XC-750 is operational next year, the extra capacity is expected to generate S10.05 million per year in additional sales, which will continue for the 10-year life of the machine. Operations: The disruption caused by the installation will decrease sales by $5.05 million this year. As with Billingham's existing products, the cost of goods for the products produced by the XC-750 is expected to be 69% of their sale price. The increased production will also require increased inventory on hand of $1.04 million during the life of the project, including year 0. Human Resources: The expansion will require additional sales and administrative personnel at a cost of $1.98 million per year Accounting: The XC-750 will be depreciated via the straight-line method over the 10-year life of the machine. The firm expects receivables from the new sales to be 14% of revenues and payables to be 10% of the cost of goods sold. Billingham's marginal corporate tax rate is 35%
