A CPA firm spends two weeks on planning, then the CFO mentions in passing that certain bank records were "lost in the move." The engagement should never have been accepted. Preconditions are the gate that closes before that mistake gets made.
Before any audit engagement is accepted, AU-C 210 requires the auditor to confirm three things. Miss one and acceptance is improper.
HIGH-FREQUENCY: The three preconditions are: (1) the financial reporting framework to be applied is acceptable, (2) management acknowledges and understands its responsibilities, and (3) the auditor and management share a common understanding of the engagement terms.
The framework must be appropriate for the entity and its intended users. Acceptable frameworks include US GAAP, IFRS, and special-purpose frameworks (cash, modified cash, tax, regulatory, contractual). A framework qualifies if set by an authorized standard setter, required by law, or accepted as a special-purpose framework for the intended users.
KEY: A cash-basis framework can be acceptable for audit purposes AND insufficient to satisfy a lender's GAAP covenant.
Common mistakes
- Treating preconditions as a planning task. Preconditions are an acceptance gate, confirmed BEFORE the engagement letter is signed. Doing risk assessment first inverts the process.
- Accepting verbal acknowledgment of management responsibilities. AU-C 210 requires written acknowledgment in the engagement letter. A handshake is not sufficient.
- Skipping the predecessor inquiry because the client wants "fresh eyes." The successor's duty does not depend on client preference. Refusal of permission is a significant concern, not an accommodation.
Bottom line
- Three preconditions must exist BEFORE acceptance: an acceptable financial reporting framework, management's acknowledgment of its responsibilities, and a common understanding of engagement terms (AU-C 210)
- A framework is acceptable if set by an authorized standard setter, required by law, or accepted as a special-purpose framework for the intended users
- Management's responsibilities are non-delegable: prepare financials, design and maintain internal control, provide unrestricted access to records and personnel, and provide written representations
- Management acknowledgment must be written in the engagement letter, verbal agreement is not sufficient
Exam shortcut
When a precondition question describes a partial-acceptance scenario ("two of three are met"), the answer is almost always decline. Preconditions are a gate, not a checklist. Memory aid: F-A-T (Framework, Acknowledgment, Terms). All three or no engagement. For predecessor communications: the duty is on the successor to ask, not the predecessor to volunteer. If the client blocks the inquiry, the answer is decline, not "proceed with extra skepticism."
