Why do managers consider direct costs to be more accurate than indirect costs?

A.

Cost tracing, which is used when assigning direct costs to a particular cost object, is more accurate than cost allocation, which is used to assign indirect costs to the same cost object.

B.

When costs are allocated, managers are less certain whether the cost allocation base accurately measures the resources demanded by a cost object, and therefore, direct costs are considered to be more accurate.

C.

Allocating indirect costs is more subjective and generally more difficult to assign to a cost object than are direct costs. Therefore, direct costs are deemed by managers to be more accurate costs than indirect costs.

D.

All of the above.
