Required:
Assume administrative and support costs vary with professional-labor costs. Consider each requirement independently.

1. How much of the total costs in 2013 are value-added, non-value-added, or in the gray area between? Explain your answers briefly. What actions can Calvert take to reduce its costs?
2. What are the consequences of misclassifying a non-value-added cost as a value-added cost? When in doubt, would you classify a cost as a value-added or non-value-added cost? Explain briefly.
3. Suppose Calvert could eliminate all errors so that it did not need to spend any time making corrections and, as a result, could proportionately reduce professional-labor costs. Calculate Calvert’s operating income for 2013.
4. Now suppose Calvert could take on as much business as it could complete, but it could not add more professional staff. Assume Calvert could eliminate all errors so that it does not need to spend any time correcting errors. Assume Calvert could use the time saved to increase revenues proportionately. Assume travel costs will remain at $15,000. Calculate Calvert’s operating income for 2013.
