Muncie Manufacturing is considering increasing its collection period by 25 days

Muncie Manufacturing is considering increasing its collection period by 25 days in hopes of attracting additional sales. Muncie currently has annual sales of $500000. They expect revenues to increase $25000 per year and expenses to increase by $10000 per year. Muncie believes that an additional $3000 will go uncollected each year as a result of this change in policy. This $3000 loss will have to be replaced each year to keep the account receivable balance at the increased 25-day level. They project that they will be able to collect 90% of the outstanding balance at the end of year 4 (after replacement). Using a 4-year life 40% tax rate and 10% required return is the investment attractive?
