AAT L4 Management Accounting: Budgeting & Evaluation 1 — Questions and Answers
Question 1: Which type of budget is most suitable for a business operating in a rapidly changing environment where forecasts quickly become outdated?
- Fixed annual budget
- Incremental budget
- Rolling (continuous) budget (Correct answer)
- Zero-based budget
Correct answer: Rolling (continuous) budget
A rolling budget is continuously updated by adding a new period as each one expires, maintaining a constant planning horizon and ensuring forecasts remain relevant in dynamic environments.
Question 2: The principal budget factor (limiting factor) must be identified before other budgets are prepared because:
- It determines the tax liability for the period
- All other budgets flow from the constraint — it determines the maximum achievable activity level (Correct answer)
- It sets the directors' remuneration
- It is required by HMRC
Correct answer: All other budgets flow from the constraint — it determines the maximum achievable activity level
The principal budget factor is the constraint limiting the organisation's activity (commonly sales demand, but can be materials, labour, or capacity). All other budgets — production, labour, materials — must be built around this constraint.
Question 3: Participative budgeting involves:
- The board of directors setting all budgets centrally
- Lower-level managers contributing to and negotiating their own budgets (Correct answer)
- An external consultant preparing the budget
- Using prior year actuals to set current year targets automatically
Correct answer: Lower-level managers contributing to and negotiating their own budgets
Participative (bottom-up) budgeting gives operational managers input into the budget-setting process, improving motivation and information quality, though it can create budget slack if not properly managed.
Question 4: Budget slack refers to:
- Time wasted during the budget preparation process
- Deliberately understating revenue or overstating costs to make targets easier to achieve (Correct answer)
- The difference between fixed and flexible budget figures
- The contingency reserve built into the capital budget
Correct answer: Deliberately understating revenue or overstating costs to make targets easier to achieve
Budget slack is the deliberate overstatement of costs or understatement of revenue by managers to create an easy-to-achieve target, reducing the risk of missing budget but distorting planning accuracy.
Question 5: A flexible budget differs from a fixed budget in that it:
- Cannot be revised once approved
- Adjusts the budgeted costs and revenues to reflect the actual level of activity achieved (Correct answer)
- Is prepared on a monthly basis rather than annually
- Is only used in manufacturing companies
Correct answer: Adjusts the budgeted costs and revenues to reflect the actual level of activity achieved
A flexible budget recalculates what revenues and costs should have been at the actual activity level, enabling meaningful variance analysis that separates the effect of activity changes from efficiency changes.
Question 6: Which of the following is a behavioural consequence of setting excessively tight (demanding) budget targets?
- Managers become more motivated to exceed targets
- Managers may become demotivated and give up if targets seem unachievable (Correct answer)
- Budget slack increases significantly
- Participative budgeting becomes unnecessary
Correct answer: Managers may become demotivated and give up if targets seem unachievable
Budget targets that are perceived as unachievable can demotivate managers, as they see no point in trying to meet them. Research suggests targets should be challenging but achievable to maximise motivation.
