Harbortown Marine Products (HMP) manufactures and sells various fixtures for boat cabins. One fixture uses a specialized fitting that is not used in any other HMP product. The management of HMP has considered outsourcing the fitting for several years but has never identified a suitable supplier.

Rivard has offered to sell HMP any quantity (up to 5,000 units monthly) at a price of $22.25 per fitting. If Rivard supplies all of the 3,300 fittings currently produced by HMP, HMP will avoid all of the variable overhead associated with the fitting and one-third of the fixed overhead. Management estimates that variable overhead for the fitting is $5.55 per unit. HMP any quantity (up to 5,000 units monthly) at a price of $22.25 per fitting.
