(29)Reliable and objective asset valuation is crucial for the protection of investor interests. AIFMs employ different methodologies and systems for valuing assets, depending on the assets and markets in which they predominantly invest. It is appropriate to recognise those differences but, nevertheless, to require in all cases AIFMs to implement valuation procedures resulting in the proper valuation of assets of AIFs. The process for valuation of assets and calculation of the net asset value should be functionally independent from the portfolio management and the remuneration policy of the AIFM and other measures should ensure that conflicts of interest are prevented and that undue influence on the employees is prevented. Subject to certain conditions, AIFMs should be able to appoint an external valuer to perform the valuation function.
