abstract:Business Valuation Standards (BVS) are codes of practice that are used in business valuation. Each of the three major United States valuation societies — the American Society of Appraisers (ASA), American Institute of Certified Public Accountants (CPA/ABV), and the National Association of Certified Valuation Analysts (NACVA) — has its own set of Business Valuation Standards, which it requires all of its accredited members to adhere to.
