The choice which valuation method you use is actually not that relevant when determining the value of a company. The company, the entrepreneur and mostly the buyer determine the value. Only when the buyer thinks the company is worth more than the seller a transaction will take place. When we draft a valuation report we usually apply several valuation methods based on economic values (future)  rather than accounting values (past). A buyer buys the future of the company and not its past, after all.
