Pacific Utilities currently uses a lockbox system of 8 boxes within their region at an after-tax cost of $14,000 per year. Elimination of the lockbox system is estimated to increase the total time it takes to convert customer payments into available funds by an average of 0.9 days. Converting from the lockbox to using other methods of payment is expected to have an after-tax cost of $11,400. They estimate that 43% of their customers will use a credit card that will have an after-tax cost of 2.8% of the collection amount. The firm collects an average of $173,000 per day. The after-tax opportunity cost of funds is 6.3% per year. Assuming the new system would go on forever (in perpetuity) after the switch, what is the NPV from eliminating their lockbox system? (Note that everything is given in after-tax terms so you don't have to make any adjustments for taxes.)
