Gage Corporation has two operating divisions in a semiautonomous organizational structure. Adams Division, located in the United States, produces a specialized electrical component that is an input to Bute Division, located in the south of England. Adams uses idle capacity to produce the component, which has a domestic market price of $10. Its variable costs are $5 per unit. Gages U.S. tax rate is 30 percent of income.

In addition to the transfer price for each component received from Adams, Bute pays a $4 per unit shipping fee. The component becomes a part of its assembled product, which costs an additional $1 to produce and sells for an equivalent of $25. Bute could purchase the component from a Manchester (England) supplier for $11 per unit. Gages English tax rate is 60 percent of income. Assume that English tax laws permit transferring at either variable cost or market price.
