McGilla Golf is evaluating selling a new line of golf clubs for five years. The clubs will generate $90,000 of annual revenue for five years with an annual variable cost of $80,000. The company has spent $31,000 for a marketing study that determined the company's expected sales. The marketing study also determined that the company will lose sales of its high-priced clubs. The high-priced clubs will have a decrease in sales resulting in a decrease in revenue of $10,000 a year as well as a decrease in variable costs of $8,000 per year. The company will also increase sales of its cheap clubs. The cheap clubs revenue will increase by $40,000 per year and have an increase in annual variable costs of $15,000. The fixed costs each year will increase by $16,000. The company has also spent $26,000 on research and development for the new clubs. The plant and equipment required will cost $55,000 and will be depreciated on a straight-line basis over ten years or $5,500 a year. The new clubs will also require an increase in net working capital of $4,000 that will be returned at the end of the project. The plant and equipment can be sold for $11,000 at the end of five years.
