Audit Engagement: formula sheet

Full chapter guide

Key formulas

Mandatory contents (SA 210, para 10)
Letter must include: (a) objective and scope; (b) auditor's responsibilities; (c) management's responsibilities; (d) applicable financial reporting framework; (e) expected form and content of reports
Remember as five items. Item (e) also needs a statement that a report may differ from its expected form and content.
Recording of terms
Agreed terms = audit engagement letter or other suitable form of written agreement
Writing is required. A verbal understanding is not enough.
Recurring audits (para 13)
Assess: (i) are revised terms needed? (ii) is a reminder of existing terms needed?
A fresh letter each year is not compulsory under the standard.
Change in terms (para 16)
New terms agreed by auditor and management and recorded in writing
Applies to a letter or other written agreement.
Factors for revising or reminding (A29)
Misunderstanding of audit scope; revised or special terms; change of senior management; significant change in ownership; significant change in nature or size of business; change in legal or regulatory requirements; change in reporting framework; change in other reporting requirements
Use these as a checklist in recurring audit questions.
Start-of-engagement activities (SA 300, para 5)
(a) client continuance procedures per SA 220 + (b) ethical compliance including independence per SA 220 + (c) understanding of engagement terms per SA 210
The auditor undertakes these at the beginning of the current audit engagement, before other significant activities.
Scope limitation rule (SA 210, para 7)
Limitation likely to cause a disclaimer → do not accept as an audit engagement, unless law or regulation requires it
Applies to limits imposed by management or those charged with governance in the proposed terms.
Preconditions failing (SA 210, para 8)
Framework unacceptable (except as provided in para 19), or the para 6(b) agreement on management's responsibilities not obtained → discuss with management; do not accept unless law or regulation requires it
Always discuss with management first.
Change in terms (SA 210, paras 15 and 17)
Request for lower assurance → check reasonable justification; if no agreement and not allowed to continue the original audit → withdraw where law permits and consider reporting obligations
Reporting may be owed to those charged with governance, owners or regulators.
Timing of continuance checks (SA 300, A8)
Continuing clients: initial procedures shortly after or with the previous audit; reconsider throughout the engagement as circumstances change
It is an ongoing process, not a one-time check.
Start-of-engagement activities (SA 300)
Continuance procedures (SA 220) + Ethics and independence (SA 220) + Engagement terms (SA 210)
Done at the beginning of the current audit engagement. Name all three in an answer.
Planning activities in setting the overall audit strategy
Scope + Reporting objectives and timing + Significant factors + Preliminary activities and other-engagement knowledge + Resources
Five items. The auditor identifies scope characteristics, ascertains reporting objectives, considers significant factors, considers preliminary results, and ascertains resources (nature, timing, extent).
Strategy and plan relationship
Overall audit strategy → Audit plan → Further audit procedures
Strategy is broad. The plan is detailed. Both are revised if conditions change.
Additional points for initial audits
Predecessor auditor arrangements + Major issues discussed with management + Opening balances (SA 510) + Firm's quality control procedures
Predecessor arrangements apply unless prohibited by law or regulation.
Right of access (SA 210 sample letter)
Access at all times to books, accounts, vouchers, records and electronic books, at Head Office or elsewhere
Extends to subsidiary records for consolidation, fraud reports, and persons within the company.
Right to information
Auditor may require from officers such information and explanations as the auditor thinks necessary
Quote the 'thinks necessary' wording. The auditor's judgement decides, not management's.
Fraud reporting
Reason to believe fraud offence → report to Board or Audit Committee for reply → forward to Central Government (Section 143(12))
Reporting in good faith is not a breach of confidentiality.
Addressee of report
Accounts report → shareholders (for adoption at AGM); other services → Board of Directors
Letter says form and content may change in light of audit findings.
Management representations
Auditor requests written confirmation of representations made during the audit
Includes pending litigations, foreseeable losses on long term contracts, and delays in IEPF transfers.
Working papers
Working papers = procedures + evidence + conclusions
Open to peer or quality reviewers for inspection and abstract.

Quick revision

  • SA 300 requires three activities at the start: client continuance procedures, ethics and independence evaluation, and understanding the terms under SA 210.
  • These initial procedures are completed before other significant audit activities.
  • For continuing clients, they often occur shortly after the previous audit.
  • Engagement terms are recorded in an engagement letter or other suitable written agreement.
  • SA 210 requires five matters in the letter: objective and scope, auditor's responsibilities, management's responsibilities, the reporting framework, and expected reports.
  • The letter must state that a report may differ from its expected form and content.
  • Where law already sets out these matters, the letter may only refer to the law and management's acknowledgement of its responsibilities.
  • The auditor should not accept a scope limitation likely to lead to a disclaimer, unless law requires it.
  • The auditor must not agree to a change of terms without reasonable justification.
  • If the request is to move to lower assurance, decide whether there is reasonable justification.
  • Agreed changes must be recorded in writing.
  • If the auditor cannot agree and is not allowed to continue, withdraw where law permits and consider reporting obligations.

Common mistakes

  • Saying the engagement letter is optional or can be oral. Fix: State that agreed terms shall be recorded in an engagement letter or other suitable written agreement.
  • Saying a fresh letter must be sent every year. Fix: Say the auditor may decide not to send a new letter, but must assess whether terms need revising or a reminder.
  • Treating acceptance as a one-time step at appointment Fix: Say that SA 300 treats continuance and ethics as ongoing through the engagement as circumstances change, with initial checks at the start of each audit.
  • Skipping independence and listing only fees and competence Fix: Always name SA 300 para 5(b): compliance with ethical requirements including independence, per SA 220.
  • Treating the audit strategy and audit plan as the same thing. Fix: Say the strategy is the broad direction and resource decision, and the plan is the detailed set of procedures that follows.
  • Saying planning is a one-time phase before fieldwork. Fix: State that planning continues and may be modified when unexpected events, changed conditions or audit evidence differ from what was expected.
  • Saying management can decide what records the auditor sees. Fix: State that access covers all relevant records, including electronic books and records kept away from the Head Office.
  • Reporting fraud straight to the Central Government. Fix: Show the sequence: report to Board or Audit Committee seeking reply, then forward to the Central Government.

Exam tips

  • Write the five mandatory contents in a list. Examiners look for all five.
  • In case questions, tie each point to a stated fact, then conclude.
  • For drafting questions, give a clear structure: addressee, objective and scope, responsibilities, framework, reports, fees, acknowledgement.
  • Keep SA 210 and SA 220 separate: terms agreed with management versus ethical requirements within the auditor's control.
  • Cite paragraph numbers only when sure. Plain statements of the rule earn marks without risk.
  • Open with the rule, then facts, then conclusion. Examiners reward the SA 300 para 5 trio of continuance, ethics and terms.
  • Quote SA numbers only where sure: SA 220 for continuance and ethics, SA 210 for terms and preconditions, SA 300 for timing.
  • In case questions, point out the red flag in the facts and say which gate it fails.
