Assurance services are a class of services provided by certified public accountants (CPAs) in public practice. While the term is sometimes used inconsistently among individual CPA firms, the American Institute of Certified Public Accountants (AICPA) Special Committee on Assurance Services defined assurance services as "independent professional services that improve the quality of information, or its context, for decision-makers."

Assurance services are rooted in the CPA's tradition of independent verification of data prepared by others. They differ from many services historically provided by CPAs in that they represent an expansion of the information and forms of reports provided. Indeed, they represent an evolution in the nature of services provided by CPAs, as CPAs have begun to provide services not just on accounting information but on many other types of information that people need in order to make decisions.

THE EVOLUTION OF CPA SERVICES

Since the early part of the twentieth century, CPAs have audited financial statements. The audit is the CPA's defining service and, aside from preparation of income taxes, the service most closely associated with the CPA profession. In an audit of financial statements, the CPA examines the transactions that underlie an entity's financial statements and reports whether the financial statements are fairly stated in conformity with generally accepted accounting principles. Such an opinion is required by the Securities and Exchange Commission (SEC) for companies whose stock is publicly traded and is often demanded by others, such as lenders, for entities that are not subject to the SEC.

Beginning in the 1970s, financial statement users requested that CPAs provide some of the benefits of audits at a lower cost. As a result, CPAs began providing a lower-level service, called a review, on financial statements. Reviews are based on inquiry and analytical procedures applied to financial statement amounts, rather than on the more rigorous procedures required in an

audit, such as physical inspection and confirmation with third parties. The review culminates in a report that provides limited assurance, that is, that the CPA is not aware of any material modifications that should be made to the accompanying financial statements in order for them to be in conformity with generally accepted accounting principles. Reviews are used for quarterly financial statements of publicly held companies. Reviews are performed for privately owned companies when the financial statement user wants some assurance about the statements but do not require the level of assurance provided in an audit.

CPAs also provide a third level of service on financial statements, the compilation. This service, provided only to privately owned companies, is usually done in connection with helping the company record its transactions and transform its records into financial statements. The accountant does not do any tests of the underlying data, but helps put the data into financial statement form and reads the statements for material misstatements. The compilation report expresses no assurance, but if the accountant discovers material misstatements, they must be corrected or described in the CPA's report.
