Communications with Audit Committees

Appendix A — Definitions

A1. For purposes of this standard, the terms listed below are defined as follows:

A2. Audit committee — A committee (or equivalent body) established by and among the board of directors of a company for the purpose of overseeing the accounting and financial reporting processes of the company and audits of the financial statements of the company; if no such committee exists with respect to the company, the entire board of directors of the company.

For audits of nonissuers, if no such committee or board of directors (or equivalent body) exists with respect to the company, the person(s) who oversee the accounting and financial reporting processes of the company and audits of the financial statements of the company.

A3. Critical accounting estimate — An accounting estimate where (a) the nature of the estimate is material due to the levels of subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change and (b) the impact of the estimate on financial condition or operating performance is material.

A4. Critical accounting policies and practices — A company's accounting policies and practices that are both most important to the portrayal of the company's financial condition and results, and require management's most difficult, subjective, or complex judgments, often as a result of the need to make estimates about the effects of matters that are inherently uncertain.
