The certification of the valuation process tends to become common best practice among investors and auditors. In Europe, a new regulation ( AIFM Directive projects) creates a third party evaluator to review fund managers’ NAVs. A rule-based automated “second opinion” on the NAVs  is the new best practice. This automated process could be viewed as an equivalent of “value at risk” or sensitivity test for the NAVs produced by fund managers.

What is the fair price of a private company? Two methods are basically applied so far:

• discounted cash flows (”DCF“)
• the comparable method (Comparables)

The DCF is criticized for being too sensitive to growth and discount rates, as well as to the calculation of a terminal value. Discount rates are implicitly given by comparables.

The comparable method remains central, notably in venture capital where cash flow projections are far from reliable. The assumption is that listed companies are evaluated on a permanent basis by buyers and sellers. By gathering a set of companies close enough to a given private company, it is possible to derive the value of the latter (discounting here and there to refine the result), assuming that:

1. Markets price listed companies correctly, integrating all the information available, which is regularly proven wrong. However the application of the comparable method can correct major biases, while a sufficiently large sample combined with the exclusion of outliers provides meaningful information.
2. Every listed company has one single price at any given point in time, which is wrong. A listed company can have different prices at one given moment, depending on (1) market liquidity -particularly in the case of double listings-, (2) nature of the exchange (OTC or stock exchange), (3) number of shares exchanged, (4) category of shares – different rights can be attached to different categories – etc… Last but not least, the market capitalization of a listed company is wrongly assumed to be its price, while the actual price can be substantially higher: In the case of a takeover bid, the buyer could typically offer a 30 percent premium.
