Paragraph 50 of the guidelines prohibits investment by UCITS in commodity indices that do not consist of different commodities and applies a correlation factor to be considered in this regard. Can UCITS invest in a commodity index for which a particular commodity component does not have 5 years of price history available for the purposes of the correlation observation?

According to paragraph 55 of the guidelines, UCITS should not invest in financial indices for which the full calculation methodology to, inter alia, enable investors to replicate the financial index, is not disclosed by the index provider. Such information should be easily accessible, free of charge. What is meant by disclosed, easily accessible and free of charge in the context of the guidelines?

According to paragraph 59 of the guidelines, UCITS should not invest in financial indices whose methodologies permit retrospective changes to previously published index values (‘backfilling’). Does this provision cover calculation mistakes?

Paragraph 61 of the guidelines recommends that financial indices in which UCITS invest should be subject to independent valuation. Does this mean that UCITS should not invest in financial indices for which the valuation is performed by the index provider itself?

Should underlying financial indices composing financial indices in which UCITS invest comply with the guidelines on financial indices?
