For the following problem, what steps, calculations, or formulas are used to compute net income? Please show how to get to the answer, not just the answer. For each of the five proposed allocation bases, compute Division As and Division Bs net income (operating income less allocated corporate overhead).

Avid, a small, privately held biotech pharmaceutical manufacturing firm, specializes in developing and producing a set of drugs for rare classes of cancers. Avid has two divisions that share the same manufacturing and research facility. The two divisions, while producing and selling two different classes of products to different market segments, share a common underlying science and related manufacturing processes. It is not unusual for the divisions to exchange technical know-how, personnel, and equipment. The following table summarizes their most current years operating performance:

	Division A	Division B
Number of employees	80	20
Plant square footage (000)	80	120
Revenues (000)	$2,000	$1,000
Operating expenses (000)	600	500
Operating profits (000)	$1,400	$ 500

Avids corporate overhead amounts to $900,000 per year. Management is debating various ways to allocate the corporate overhead to the two divisions. Allocation bases under consideration include: number of employees, plant square footage, revenues, operating expenses, and operating profits. Each division is treated as a separate profit center with each manager receiving a bonus based on his or her divisions net income (operating profits less allocated corporate overhead).
