What are revenues for Year 2?

13,000 × $71 = $923,000


13,000 × $53.50 = $695,500

Is there a volume variance?

(12,000 – 11,500) × $4.50 = $2,250underallocated fixed manufacturing costs




What is the gross margin?

$923,000 – ($695,500 + $2,250) = $225,250

What are the nonmanufacturing costs?

13,000 units sold × $2.00 = $26,000variable costs + $30,000 fixed costs = $56,000




What is the operating income before taxes?

$225,250 – $56,000 = $169,250

Comparison of Variableand Absorption CostingComparison of Variableand Absorption Costing

Variable costing operating income Year 1: $76,000

Absorption costing operating income Year 1: $85,000

Absorption costing operating income is $9,000 higher.

Why?



Production exceeds sales in Year 1.

The 2,000 units in ending inventoryare valued as follows:

Absorption costing: 2,000 × $53.50 = $107,000

Variable costing: 2,000 × $49.00 = $ 98,000

Difference: $ 9,000



Variable costing operating income Year 2: $176,000

Absorption costing operating income Year 2: $169,250

Variable costing operating income is $6,750 higher.

Why?



Sales exceeded units produced in Year 2.

13,000 – 11,500 = 1,500 decrease in inventory

Absorption costing: 1,500 × $53.50 = $80,250

Variable costing: 1,500 × $49.00 = $73,500

Higher cost of goods sold underabsorption costing: $ 6,750



Variable costing combined net income: $252,000

Absorption costing combined net income: $254,250

Absorption costing is higher by $2,250

500 units in inventory × $4.50 = $2,250

Inventory BuildupInventory Buildup

What is the production volume variance?

(12,000 – 4,400) × $4.50 = $34,200 U

What is the net operating income or lossfor the period?

Assume that Davenport Fixtures produced4,400 units in Year 1 and sold 4,100.



Revenues (4,100 × $71) $291,100Cost of goods sold (4,100 × $53.50) 219,350Volume variance 34,200Gross margin $ 37,550Nonmanufacturing costs 38,200Net loss $ 650



4,400 – 4,100 = 300

How much cost is in ending inventory?

300 × $53.50 = $16,050

How many units are in ending inventory?



Sales remain the same (4,100 units).

What is the volume variance?

(12,000 – 9,000) × $4.50 = $13,500 U

Suppose that management decides toproduce 9,000 units next year.

What is the operating income or loss?



Revenues (4,100 × $71) $291,100Cost of goods sold (4,100 × $53.50) 219,350Volume variance 13,500Gross margin $ 58,250Nonmanufacturing costs 38,200Net income $ 20,050



300 + 9,000 – 4,100 = 5,200

How much cost is in ending inventory?

5,200 × $53.50 = $278,200

How many units are in ending inventory?

Budgeted Fixed ManufacturingOverhead Rate


Lloyd’s Bicycles produces bicycle partsfor domestic and foreign markets.

Fixed overhead costs are $200,000 within therelevant range of the various capacity volume.




Assume that the theoretical capacity is10,000 machine-hours, practical capacity

is 85%, normal capacity is 75%, andmaster-budget capacity is 60%.

What is the budgeted fixed manufacturingoverhead rate at the various capacity levels?




Theoretical 100%:$200,000 ÷ 10,000 = $20.00/machine-hour

Practical 85%:$200,000 ÷ 8,500 = $23.53/machine-hour

Normal 75%:$200,000 ÷ 7,500 = $26.67/machine-hour

Master-budget 60%:$200,000 ÷ 6,000 = $33.33/machine-hour



Understand the major factorsmanagement considers in choosing

a capacity level to compute thebudgeted fixed overhead cost rate.

Regulatoryrequirements

Difficulty


Decision MakingDecision Making

Assume that Lloyd’s Bicycles’ standardhours are 2 hours per unit.

What is the budgeted fixed manufacturingoverhead cost per unit?


Decision MakingDecision Making

Theoretical capacity: $20 × 2 = $40.00

Practical capacity: $23.53 × 2 = $47.06

Normal capacity: $26.67 × 2 = $53.34

Master-budget capacity: $33.33 × 2 = $66.66



Describe how attempts torecover fixed costs of capacity

may lead to price increasesand lower demand.


Downward Demand Spiral

The downward demand spiral is the continuingreduction in demand that occurs when the pricesof competitors are not met and demand drops.



Explain how the capacitylevel chosen to calculate

the budgeted fixed overheadcost rate affects the

production-volume variance.


Effect on Financial StatementsEffect on Financial Statements

Assume that Lloyd’s Bicycles actually used8,400 machine-hours during the year.

What is the production volume variance?


Production Volume VarianceProduction Volume Variance

Production volume variance= (Denominator level – Actual level)

× Budgeted fixed manufacturing overhead rate

Theoretical capacity:(10,000 – 8,400) × $20.00 = $32,000 U

Practical capacity:(8,500 – 8,400) × $23.53 = $2,353 U


Production Volume VarianceProduction Volume Variance

Normal capacity:(7,500 – 8,400) × $26.67 = $24,003
