Definition, Objective and general principles governing an audit (ISA – 200) Khawar Shahzad Jaffar ACCA, CPA
Audit 
An audit is independent examination of financial statements and related information of an entity with a view to express an opinion.

Auditing is a systematic process of objectively obtaining and evaluating evidence regarding assertions about economic actions and events to ascertain the degree of correspondence between those assertions and established criteria and communicating the results to interested users.
Objective of Audit
The objective of an audit is to enable the auditor to express an opinion whether the financial statements are prepared, in all material respects, in accordance with an identified financial reporting framework.
It is management’s responsibility to prepare the financial statements.
Auditor’s responsibility is to give reasonable assurance that the financial statements give a true and fair picture.
Audit Opinion 
The audit opinion is given on whether the financial statements give a true and fair view of the entity’s financial statements and whether they have been properly prepared in accordance with the applicable reporting framework.
Audit Opinion
This opinion is reached after:
Extensive risk assessment has been performed.
Extensive testing of controls and substantive tests on transactions and balances for validity, accuracy and completeness of recording.
Extensive verification procedures have been performed to test for existence, ownership, valuation, presentation and disclosure of items in the financial statements.
Extensive review of whether the financial statements comply with applicable accounting standards and legal requirements.
Applicable Reporting Framework 
The financial reporting framework adopted by management and, where appropriate, those charged with governance in the preparation of the financial statements that is acceptable in view of the nature of the entity and the objective of the financial statements, or that is required by law or regulation.
Audit Evidence 
Information used by the auditor in arriving at the conclusions on which the auditor’s opinion is based. Audit evidence includes both information contained in the accounting records underlying the financial statements and other information.
Audit Evidence
For purposes of the ISAs: Sufficiency
of audit evidence is the measure of the quantity of audit evidence. The quantity of the audit evidence needed is affected by the auditor’s assessment of the risks of material misstatement and also by the quality of such audit evidence.
Appropriateness
of audit evidence is the measure of the quality of audit evidence; that is, its relevance and its reliability in providing support for the conclusions on which the auditor’s opinion is based.
Audit Risk 
The risk that the auditor expresses an inappropriate audit opinion when the financial statements are materially misstated. Audit risk is a function of the risks of material misstatement and detection risk.
Detection Risk 
The risk that the procedures performed by the auditor to reduce audit risk to an acceptably low level will not detect a misstatement that exists and that could be material, either individually or when aggregated with other misstatements.
Risk of Material Misstatement 
The risk that the financial statements are materially misstated prior to audit. This consists of two components, described as follows at the assertion level:  Inherent
Risk – The susceptibility of an assertion about a class of transaction, account balance or disclosure to a misstatement that could be material, either individually or when aggregated with other misstatements, before consideration of any related controls.
Risk of Material Misstatement  Control
Risk – The risk that a misstatement that could occur in an assertion about a class of transaction, account balance or disclosure and that could be material, either individually or when aggregated with other misstatements, will not be prevented, or detected and corrected, on a timely basis by the entity’s internal control.
Materiality 
Transactions, items, events will be material in financial statements if their omission, misstatement, misclassification or non-disclosure would distort the view given by the financial statements and would responsibly influence the understanding and economic decisions of users.

Materiality, however, is not capable of general mathematical definition since it involves qualitative as well as quantitative considerations.
Misstatement 
A difference between the amount, classification, presentation, or disclosure of a reported financial statement item and the amount, classification, presentation, or disclosure that is required for the item to be in accordance with the applicable financial reporting framework. Misstatements can arise from error or fraud.
Professional Judgment 
The application of relevant training, knowledge and experience, within the context provided by auditing, accounting and ethical standards, in making informed decisions about the courses of action that are appropriate in the circumstances of the audit engagement.
Professional Skepticism 
An attitude that includes a questioning mind, being alert to conditions which may indicate possible misstatement due to error or fraud, and a critical assessment of audit evidence.
Reasonable Assurance
In the context of an audit of financial statements, a high, but not absolute, level of assurance. Positive
Assurance
Negative
Assurance
True and Fair View
Auditor shall state in audit report whether the financial statements give a “true and fair view” or “present fairly, in all material respects” (both are equilents terms)

Based

True and Fair View
By “fair” is meant that the financial statements are: Objectively Free
