International Standards on Auditing (ISAs) are professional standards for the auditing of financial information. These standards are issued by the International Auditing and Assurance Standards Board (IAASB), which is a standard-setting body that operates under the auspices of the International Federation of Accountants (IFAC).

Historical Context

The origins of the ISAs date back to the establishment of the International Federation of Accountants (IFAC) in 1977. The need for a global standard was recognized to ensure consistency and quality in auditing practices worldwide. In 1978, the IAASB, initially known as the International Auditing Practices Committee (IAPC), began the process of developing and issuing International Standards on Auditing.

Types/Categories

ISAs cover various aspects of the audit process, including but not limited to:

General Principles and Responsibilities: ISAs 200-299
Risk Assessment and Response to Assessed Risks: ISAs 300-499
Audit Evidence: ISAs 500-599
Using Work of Others: ISAs 600-699
Audit Conclusions and Reporting: ISAs 700-799
Specialized Areas: ISAs 800-899

Key Events

1978: Formation of the International Auditing Practices Committee (IAPC).

Detailed Explanations

ISAs aim to enhance the quality and consistency of audits globally. They provide a comprehensive framework that auditors can follow to ensure they conduct their work to high professional standards. Key standards include:

ISA 200: Overall objectives of the Independent Auditor and the Conduct of an Audit in Accordance with ISAs.
ISA 240: The Auditor’s Responsibilities Relating to Fraud in an Audit of Financial Statements.
ISA 315: Identifying and Assessing the Risks of Material Misstatement through Understanding the Entity and Its Environment.

Mathematical Formulas/Models

Although ISAs are guidelines and principles rather than quantitative models, they often use statistical methods for sampling and risk assessment. Key formulas include:

Audit Sampling Formula: $\text{Sample Size} = \left( \frac{\text{Population Size} \times \text{Desired Confidence Level}}{\text{Expected Error Rate}} \right)$
