Audit

Auditing refers to a systematic examination of books, accounts, documents and vouchers of an organization to ascertain how far the financial statements present a true and fair view of the concern. It also attempts to ensure that the books of accounts are properly maintained by the concern as required by law. Auditing has become such an ubiquitous phenomenon in the corporate and the public sector that academics started identifying an "Audit Society".^[1]

Auditing is defined as a systematic and independent examination of data, statements, records, operations and performances (financial or otherwise) of an enterprise for a stated purpose. In any auditing the auditor perceives and recognizes the propositions before him/her for examination, collects evidence, evaluates the same and on this basis formulates his/her judgment which is communicated through his/her audit report.^[2]

Any subject matter may be audited. Audits provide third party assurance to various stakeholders that the subject matter is free from material misstatement. The term is most frequently applied to audits of the financial information relating to a legal person. Other areas which are commonly audited include: internal controls, quality management, project management, water management, and energy conservation.

As a result of an audit, stakeholders may effectively evaluate and improve the effectiveness of risk management, control, and the governance process over the subject matter

.Due to strong incentives (including taxation, misselling and other forms of fraud) to misstate financial information, auditing has become a legal requirement for many entities who have the power to exploit financial information for personal gain. Traditionally, audits were mainly associated with gaining information about financial systems and the financial records of a company or a business.

Financial audits are performed to ascertain the validity and reliability of information, as well as to provide an assessment of a system's internal control. As a result of this, a third party can express an opinion of the person / organization / system (etc.) in question. The opinion given on financial statements will depends on the audit evidence obtained.

Due to constraints, an audit seeks to provide only reasonable assurance that the statements are free from material error. Hence, statistical sampling is often adopted in audits. In the case of financial audits, a set of financial statements are said to be true and fair when they are free of material misstatements – a concept influenced by both quantitative (numerical) and qualitative factors. But recently, the argument that auditing should go beyond just true and fair is gaining momentum.^[3] And the US Public Company Accounting Oversight Board has come out with a concept release on the same.^[4]

Cost accounting is a process for verifying the cost of manufacturing or producing of any article, on the basis of accounts measuring the use of material, labor or other items of cost. In simple words, the term, cost audit means a systematic and accurate verification of the cost accounts and records, and checking for adherence to the cost accounting objectives. According to the Institute of Cost and Management Accountants of Pakistan, a cost audit is "an examination of cost accounting records and verification of facts to ascertain that the cost of the product has been arrived at, in accordance with principles of cost accounting."^{[citation needed]}

In most nations, an audit must adhere to generally accepted standards established by governing bodies. These standards assure third parties or external users that they can rely upon the auditor's opinion on the fairness of financial statements, or other subjects on which the auditor expresses an opinion.

Auditors

Auditors of financial statements can be classified into two categories:

External auditor / Statutory auditor is an independent firm engaged by the client subject to the audit, to express an opinion on whether the company's financial statements are free of material misstatements, whether due to fraud or error. For publicly traded companies, external auditors may also be required to express an opinion over the effectiveness of internal controls over financial reporting. External auditors may also be engaged to perform other agreed-upon procedures, related or unrelated to financial statements. Most importantly, external auditors, though engaged and paid by the company being audited, should be regarded as independent.

Cost auditor / Statutory Cost auditor is an independent firm engaged by the client subject to the Cost audit, to express an opinion on whether the company's Cost statements and Cost Sheet are free of material misstatements, whether due to fraud or error. For publicly traded companies, external auditors may also be required to express an opinion over the effectiveness of internal controls over Cost reporting. These are Specialized Persons called Cost Accountants in India & CMA globally either Cost & Management Accountants or Certified Management Accountants.

The most commonly used external audit standards are the US GAAS of the American Institute of Certified Public Accountants; and the ISAInternational Standards on Auditing developed by the International Auditing and Assurance Standards Board of the International Federation of Accountants.^{[citation needed]}

Internal auditors are employed by the organizations they audit. They work for government agencies (federal, state and local); for publicly traded companies; and for non-profit companies across all industries. The internationally recognised standard setting body for the profession is the Institute of Internal Auditors - IIA (www.theiia.org). The IIA has defined internal auditing as follows: "Internal auditing is an independent, objective assurance and consulting activity designed to add value and improve an organization's operations. It helps an organization accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, control, and governance processes".^[6] Thus professional internal auditors provide independent and objective audit and consulting services focused on evaluating whether the board of directors, shareholders, stakeholders, and corporate executives have reasonable assurance that the organization's governance, risk management, and control processes are designed adequately and function effectively. Internal audit professionals (Certified Internal Auditors - CIAs) are governed by the international professional standards and code of conduct of the Institute of Internal Auditors.^[7] While internal auditors are not independent of the companies that employ them, independence and objectivity are a cornerstone of the IIA professional standards; and are discussed at length in the standards and the supporting practice guides and practice advisories. Professional internal auditors are mandated by the IIA standards to be independent of the business activities they audit. This independence and objectivity are achieved through the organizational placement and reporting lines of the internal audit department. Internal auditors of publicly traded companies in the United States are required to report functionally to the board of directors directly, or a sub-committee of the board of directors (typically the audit committee), and not to management except for administrative purposes. As described often in the professional literature for the practice of internal auditing (such as Internal Auditor, the journal of the IIA) -,^[8] or other similar and generally recognized frameworks for management control when evaluating an entity's governance and control practices; and apply COSO's "Enterprise Risk Management-Integrated Framework" or other similar and generally recognized frameworks for entity-wide risk management when evaluating an organization's entity-wide risk management practices. Professional internal auditors also use Control Self-Assessment (CSA) as an effective process for performing their work.

Consultant auditors are external personnel contracted by the firm to perform an audit following the firm's auditing standards. This differs from the external auditor, who follows their own auditing standards. The level of independence is therefore somewhere between the internal auditor and the external auditor. The consultant auditor may work independently, or as part of the audit team that includes internal auditors. Consultant auditors are used when the firm lacks sufficient expertise to audit certain areas, or simply for staff augmentation when staff are not available.
