Which statement about periodic budgets is least accurate?

• A. They are prepared only once for the full budget period.
• B. They are used to manage operations during the period.
• C. They are updated at least quarterly.
• D. They are never updated during the budget period.

Answer: (D)

Periodically updating plans as conditions change is a fundamental idea behind budgets used for control. A budget isn’t a one-off document that sits untouched; it serves as a living forecast that guides decisions and operations throughout the period. Because things like sales levels, inputs costs, or market conditions can shift, you revise the budget as new information comes in, typically at least every quarter. In fast-moving environments, updates might occur even more often, such as monthly, to keep forecasts aligned with reality.

The statement that budget updates never happen during the period is therefore the least accurate. Budgets that are truly used for management control are expected to be reviewed and updated to reflect updated assumptions, progress, and new expectations. The other statements fit this approach: the budget covers the full period it’s intended for and it is used to manage operations during that period.
