# Assurance Engagements & Engagement Standards Framework

## What is an Assurance Engagement?

An engagement in which a practitioner expresses a conclusion designed to enhance the degree of confidence of intended users (other than the responsible party) about the outcome of the evaluation of a subject matter against criteria.

Note: ‘Practitioner' is a broader term than ‘auditor'. An audit relates only to historical financial information, whereas assurance may or may not.

## Five Elements of an Assurance Engagement

1. Three-party relationship —

Practitioner — who provides the assurance.
Responsible party — responsible for the subject matter.
Intended users — for whom the report is prepared.

2. Appropriate subject matter — e.g., the FS.

3. Suitable criteria — benchmarks against which the subject matter is evaluated (e.g., Accounting Standards).

4. Sufficient appropriate evidence — on which the conclusion is based.

5. A written assurance report in appropriate form.

## Levels of Assurance

Type	Level of Assurance	Example
Absolute assurance	Complete (rarely achievable)	—
Reasonable assurance	High level	Audit of FS
Limited assurance	Moderate level	Review of FS

### Reasonable vs Limited Assurance

Reasonable Assurance Engagement	Limited Assurance Engagement
Provides high level of assurance	Provides moderate level of assurance
Performs elaborate & extensive procedures to obtain SAAE	Performs fewer procedures
Draws reasonable conclusions	Draws limited conclusions
Example: Audit	Example: Review

## Engagement Standards — The Family

Standard	Purpose
SAs – Standards on Auditing	Audit of historical FS
SREs – Standards on Review Engagements	Review of historical FS
SAEs – Standards on Assurance Engagements	Assurance engagements other than audit/review of historical info (e.g., prospective FS)
SRSs – Standards on Related Services	Agreed-upon procedures & compilation engagements

Collectively, these four are known as the Engagement Standards.

## Standard on Quality Control (SQC)

SQC provides guidance for a firm's quality control system. It is applicable to all services covered by the Engagement Standards.

## Prospective Financial Information (under SAEs)

Prospective FS — FS based on assumptions about events that may occur in the future and possible actions by the entity. Can be a forecast, projection, or both.
The practitioner obtains SAAE that management's assumptions are not unreasonable and that all material assumptions are properly disclosed.
The report provides moderate level of assurance — stating that nothing has come to the practitioner's attention suggesting that the assumptions do not provide a reasonable basis for the projection.

## Why are Standards Needed?

Ensure audit is conducted against established global benchmarks.
Promote uniformity in audit.
Ensure quality of audit work.
Improve quality of financial reporting.
Equip accountants with professional knowledge and skill.

## Duties in Relation to Standards

Accountants have a duty to follow Standards.
If a specific procedure is ineffective in a particular engagement, the reason for departure must be documented, along with how alternative procedures achieve the purpose.
The auditor's report must draw attention to such departures.
⚠️ Mere disclosure of departure in the report does NOT absolve the auditor from complying with Standards.

## Origin of Auditing

Reference to auditing is found in Kautilya's Arthashastra, 4th century BC.
The word audit comes from the Latin word audire, meaning to hear.
1st Auditor General of India was appointed in British India in 1860.

## Examples of Assurance Engagements (Not Limited to FS Audit)

Example	Type of Assurance
Audit of FS	Reasonable assurance
Review of FS	Limited assurance
Examination of prospective financial information	Assurance regarding reasonableness of assumptions
Report on controls operating at an organisation	Assurance regarding design and operation of controls

Worked example

### Example 1

Example — Identifying the Engagement Standard

A practitioner is engaged to perform an agreed-upon procedure on debtors' confirmations of XYZ Ltd as required by its bank.

This is governed by SRSs (Standards on Related Services) — not SAs, because it is not an audit or review.
The practitioner reports factual findings only; no opinion is expressed.

### Example 2

Example — Departure from a Standard

Mr C, while auditing a small NGO, finds that the standard procedure of external confirmation is impractical because all donors are anonymous walk-in donors.

He may depart from the standard procedure but must (i) document the reason, (ii) document how alternative procedures achieved the same purpose, and (iii) draw attention to the departure in his report.
Importantly, merely disclosing the departure does not absolve him from compliance — he must show the alternative procedure was effective.

⚠️ Common exam mistakes

Confusing ‘practitioner' with ‘auditor' — practitioner is the broader term; every auditor is a practitioner, but not every practitioner is an auditor.
Writing that absolute assurance is provided by an audit — audit provides only reasonable assurance.
Forgetting that SQC applies to all services under engagement standards, not just audits.
Believing that mere disclosure of departure from a Standard discharges the auditor's duty — it does not.
