1. Hitchner, J. R. (2017). Financial Valuation: Applications and Models (4th ed.). In Chapter 3, "Valuation Approaches and Methods," the text emphasizes that the selection of methods is based on factors such as the purpose of the valuation, the availability of data, and the specific characteristics of the subject interest, all of which require the analyst's professional judgment. The specific accounts are inputs to the chosen method, not determinants of it.
2. NACVA. (2023). Fundamentals, Techniques & Theory (FT&T). The core training material for the CVA designation repeatedly states that the valuation process involves selecting appropriate methods based on the purpose and nature of the engagement, the availability of information, and the analyst's judgment. For instance, Section IV, "Valuation Approaches/Methods," details how these factors guide the choice between asset, income, and market approaches.
3. AICPA. (2007). Statement on Standards for Valuation Services No. 1 (SSVS 1), Valuation of a Business, Business Ownership Interest, Security, or Intangible Asset. Paragraph 34 states, "The selection of the valuation approaches and methods... is a matter of the valuation analyst’s professional judgment." The standard implicitly supports that this judgment is based on the purpose, available data, and other engagement-specific factors.
