Mile-High Foods, Inc., was formed in March 2011 to provide prepackaged snack boxes for a new low cost regional airline beginning on April 1. The company has just leased warehouse space central to the two airports to store materials.

To move package materials from the warehouse to the airports, where final assembly will take place, Mile-High must choose whether to lease a delivery truck and pay a full-time driver at a fixed cost of $5000 per month, or pay a delivery service a rate equivalent to $0.40 per box. This cost will be included in either fixed manufacturing overhead or variable manufacturing overhead, depending on which option is chosen. The company is hoping for rapid growth, as sales forecasts for the new airline are promising. However, it is essential that Mile-High managers carefully costs in order to be compliant with their sales contract and remain profitable.

Ron Spencer, the company's president, is trying to determine whether to use absorption costing, variable, or throughput costing to evaluate the performance of company managers. For absorption costing, he intends to use the practical capacity level of the facility, which is 20000boxes per month. Production volume variance will be written off to cost of goods sold.

Cost for the three months are expected to remain unchanged. The costs and revenue for April, May, and June are expected to be as follow;

Sales Revenue $6.00 per box

Dierct material cost $1.20 per box

Direct manufacturing labor cost $0.35 per box

Variable manufacturing overhead cost $0.15 per box

Variable delivery cost (if this option is chosen) $0.40 per box

Fixed delivery cost (if this option is chosen) $5000 per month

Fixed manufacturing overhead costs $15000 per month

Fixed administrative costs $28000 per month

Projected production and sales for each month follow. High production in May is the result of an anticipated surge in June employee vacations.

Sales (in units) Production

April 12000 12200

May 12500 18000

June 13000 9000

Total 37500 39200

1. Compute an operating income for April, May, and June under absorption costing, assuming that Mile-High opts to use; (a) the leased truck driver and salaried driver (b) the variable delivery service

2. Compute an operating income for April, May, and June under variable costing, assuming that Mile-High opts to use; (a) the leased truck driver and salaried driver (b) the variable delivery service

3. Compute an operating income for April, May, and June under throughput costing, assuming that Mile-High opts to use; (a) the leased truck driver and salaried driver (b) the variable delivery service

4. Should Mile-High choose absorption, variable, or throughput costing for evaluating the performance of managers? Why? What advantages and disadvantages might there be in adopting throughput costing?

5. Should Mile-High opt for the leased truck and salaried driver or the variable delivery service? Explain briefly.
