Final answer:
The recommended transfer price for Cascade Containers' internal transactions between Manufacturing and Distribution, ignoring tax implications and considering excess capacity, should be at least the variable cost of $300 per unit, which covers the cost of producing additional units.
Step-by-step explanation:
The question relates to setting an appropriate transfer price for Cascade Containers where its Manufacturing division produces goods for the Distribution division. Since Manufacturing has excess capacity, the transfer price should cover the variable cost of manufacturing and potentially some contribution to fixed costs, without considering the tax implications. The marginal cost to produce each additional unit is the variable cost, which is $300. As there is excess capacity, the opportunity cost of selling internally as opposed to selling externally is zero. Consequently, Manufacturing would not be sacrificing external sales by fulfilling the internal demand.
Therefore, the recommended transfer price, in this case, would be at least the variable cost of $300 per unit. This approach ensures that the Manufacturing division covers its costs of producing the additional units and may contribute to covering fixed costs, without taking into account the tax difference between the two countries.
