Example of an Audit Engagement Letter
The following letter is for use as a guide in conjunction with the considerations outlined in this ISA and will need to be varied according to individual requirements and circumstances.
To the Board of Directors or the appropriate representative of senior management:
You have requested that we audit the balance sheet of …………..as of …………., and the related statements of income and cash flows for the year then ending. We are pleased to confirm our acceptance and our understanding of this engagement by means of this letter. Our audit will be made with the objective of our expressing an opinion on the financial statements.
We will conduct our audit in accordance with International Standards on Auditing (or relevant national standards or practices). Those ISAs require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatements. An
audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial statement presentation.
Because of the test nature and other inherent limitations of an audit, together with the inherent limitations of any accounting and internal control system, there is an unavoidable risk that even some material misstatements may remain undiscovered.
In addition to our report on the financial statements, we expect to provide you with a separate letter concerning any material weaknesses in accounting and internal control systems, which come to our notice.
We remind you that the responsibility for the preparation of financial statements including adequate disclosure is that of the management of the company. This includes the maintenance of adequate accounting records and internal controls, the selection and application of accounting policies, and the safeguarding of the assets of the company. As part of our audit process, we will request from management written confirmation concerning representations made to us in connection with the audit.
We look forward to full cooperation with your staff and we trust that they will make available to us whatever records, documentation and other information are requested in connection with our audit.
Our fees, which will be billed as work progress, are based on the time required by the individuals assigned to the engagement plus out-of-pocket expenses. Individual hourly rates vary according to the degree of responsibility involved and the experience and skill required.
This letter will be effective for future years unless it is terminated, amended or superseded.
Please sign and return the attached copy of this letter to indicate that it is in accordance with your understanding of the arrangements for our audit of the financial statements.
