is not generally accepted for external reporting purposes or for tax
purposes.
b. The Finished Goods inventory account should be stated at $90,000,

These expenses are always treated as period costs.

Net operating income ............................................
$ 0
Note: The company has a zero net operating income even though its
sales are below the break-even point computed in Exercise 6-14. This
occurs because $35,000 of fixed manufacturing overhead has been
deferred in inventory and does not appear on the income statement
prepared using absorption costing.
Exercise 6-16 (20 minutes)
1. The companywide break-even point is computed as follows:
Dollar sales for company
to break even
=
Traceable fixed expenses + Common fixed expenses
Overall CM ratio
=
$126,000 + $63,000
0.50
=
$189,000
0.50
=
$378,000
The break-even point for the Chicago office is computed as follows:
Dollar sales for a
segment to break even
=
Segment traceable fixed expenses
Segment CM ratio
=
$78,000
0.70
=
$111,429 (rounded)

b. The segment margin ratio rises and falls as sales rise and fall due to
the presence of fixed costs. The fixed costs are spread over a larger
base as sales increase.
In contrast to the segment ratio, the contribution margin ratio is
stable so long as there is no change in either the variable expenses or
the selling price per unit of service.

partly traceable and partly common. When we segment Minneapolis by
market, only $33,000 remains a traceable fixed expense. This amount

contribution margin per unit as follows:
Selling price per unit .....................

Contribution margin per unit .........
$20
Break-even unit sales = Fixed expenses ÷ Unit contribution margin
= $1,200,000 ÷ $20 per unit

The absorption costing net operating incomes in years 2 and 3 are counter-intuitive. In year 2, the
number of units sold is below the break-even point; however, absorption costing reports a net
operating income greater than zero. In year 3, the number of units sold is above the break-even
point; however, absorption costing reports a net operating income less than zero.

handling of fixed manufacturing overhead costs. Under variable costing,
these costs have been expensed in full as period costs. Under
absorption costing, these costs have been added to units of product at
