Comprehensive overview of the basic principles and essential procedures auditors must comply with during an audit of financial statements.

Introduction

Auditing standards are the cornerstone of auditing practices, providing a framework that guides auditors in their assessment of financial statements. They ensure the consistency, reliability, and transparency of audits, reinforcing public confidence in financial reporting.

Historical Context

The development of auditing standards can be traced back to the formation of various auditing bodies. Notably:

1980-1991: The Auditing Practices Committee (APC) issued three primary standards.
Post-1991: The successor, Auditing Practices Board (APB), introduced Statements of Auditing Standards (SAS).
2009-2010: A new series of International Standards on Auditing (ISA) was established by the International Auditing and Assurance Standards Board (IAASB).

Types/Categories of Auditing Standards

General Standards: Foundational principles regarding auditors’ qualifications, integrity, and due professional care.
Fieldwork Standards: Guidelines for planning audits, supervising assistants, and gathering sufficient evidence.
Reporting Standards: Requirements for audit reports, including the content and the clarity of the audit opinion.

Key Events in Auditing Standards Development

1980-1991: Introduction of initial Auditing Standards by APC.
Post-1991: Transition to APB’s Statements of Auditing Standards.
2009-2010: Shift to International Standards on Auditing (ISA).

Detailed Explanations

General Standards

Qualifications: Auditors must possess adequate technical training and proficiency.
Independence: Auditors must maintain independence in mental attitude.
Due Professional Care: Auditors must exercise professional skepticism and care.

Fieldwork Standards

Planning and Supervision: Proper planning and supervision are critical for audit effectiveness.
Understanding the Entity: Auditors must have a comprehensive understanding of the entity and its environment.
Evidence Collection: Collecting sufficient and appropriate evidence is paramount.

Reporting Standards

Report Content: The auditor’s report should clearly state whether financial statements comply with the applicable financial reporting framework.
Opinion: The auditor’s opinion on the financial statements must be explicit and based on reliable evidence.

Mathematical Formulas/Models

While auditing standards do not typically involve mathematical formulas, the methodology might include statistical sampling, which can be expressed as:

1n = (Z^2 * P(1-P))/E^2

Where:

n is the sample size.
Z is the Z-value (standard deviation) corresponding to the confidence level.
P is the estimated proportion of an attribute present in the population.
E is the margin of error.
