Final answer:
The net benefit of adopting the lockbox system is $432,979, calculated by the additional interest income earned from the earlier release of funds due to a reduced payment processing cycle, after accounting for the cost of the lockbox service.
Step-by-step explanation:
The question involves determining the net present value (NPV) of establishing a new lockbox system for a company's payment collections. By shifting customer payments to a bank lockbox, the company can reduce the payment processing cycle by 5 days (3 days in mailing time and 2 days in processing time). With the company collecting $365 million annually, and an average of 1000 payments per day, we can calculate the daily collections as $365,000,000 / 365 = $1,000,000. The lockbox will hence release $1,000,000 of funds 5 days earlier, which at a 10% annual interest rate, converts to an interest income of ($1,000,000 * 5/365 * 10%) = $1,369.86 per day.
The annual cost of the lockbox service is the $25,000 fixed fee plus $0.12 per payment, which totals $25,000 + ($0.12 * 1000 * 365) = $67,000. The annual interest income from the released funds is $1,369.86 * 365 = $499,979. The net benefit is the interest income minus the cost of the lockbox service, which is $499,979 - $67,000 = $432,979.
