PROBLEM B-5 Interpreting Common Practice [LO1] In practice, many organizations measure the relative profitability of their segments by dividing the segments' margins by their revenues. The segment margin for this purpose is the segment's revenue less its fully allocated costs-including allocations of fixed common costs. For example, a hospital might compute the relative profitability of its major segments as follows: The hospital's net operating income for this period was $1,240,000. Required: 1.
