Audit and Assurance

International Standards on Auditing

"In conducting an audit of financial statements, the overall objectives of the auditor are:

(a)To obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, thereby enabling the auditor to express an opinion on whether the financial statements are prepared, in all material respects, in accordance with an applicable financial reporting framework; and
(b) To report on the financial statements,
and communicate as required by the ISAs (Ireland), in accordance with the auditor’s findings.”
(ISA (Ireland)200 paragraph 11)
In order to meet this challenge auditor’s carry out audit engagements under a set of standards called International Standards on Auditing (ISA). These may be ISAs (Ireland) or ISAs (UK) depending on the location of the engagement.
