ACCA · Question 29 · Responsibility Accounting

Section B - Case 3: UrbanTransit

UrbanTransit operates a fleet of municipal buses. The company uses a standard costing system to monitor fuel costs.

At the start of the year, the original standard price for diesel was set at $2.00 per liter.
Mid-year, due to a global geopolitical shock, the market price of diesel surged. Management revised the standard price to $2.50 per liter to reflect uncontrollable market conditions.

During the last quarter, UrbanTransit purchased and used 100,000 liters of diesel at an actual total cost of $260,000.

Which TWO of the following statements regarding responsibility for these variances are correct?

Answer options:

A.

The purchasing manager should be held accountable for the $50,000 planning variance.

B.

The purchasing manager should be held accountable for the $10,000 operational variance.

C.

The planning variance indicates that the original budget was based on faulty assumptions or unforeseen external events.

D.

The operational variance should be ignored because the market is too volatile.

How to approach this question

Understand the purpose of splitting variances. Planning = uncontrollable (market shock). Operational = controllable (negotiation skills).

Full Answer

The primary reason for splitting variances into planning and operational components is responsibility accounting. The planning variance ($50,000 A) is caused by uncontrollable external market shocks, so the purchasing manager is not held responsible. The operational variance ($10,000 A) reflects the manager's failure to procure fuel at the revised, realistic market rate of $2.50, so they are held accountable for this portion.

Common mistakes

Assuming the manager is responsible for the total variance, which defeats the purpose of revising standards.
