Lipper Methodology: The currency for the calculation corresponds to the currency of the country for which the awards are calculated and relies on monthly data. Classification averages are calculated with all eligible share classes for each eligible classification. The calculation periods extend over 36, 60 and 120 months. The highest Lipper Leader® for Consistent Return (Effective Return) value within each eligible classification determines the fund classification winner over three, five or 10 years.
