WIG20dvp index is calculated on the basis of ordinary dividends paid by the constituents of the WIG20 index (underlying index). The base date of WIG20dvp was set at January 2, 2007. The dividend is reflected in the index on the ex-dividend date (trading day following the last day of quoting the shares with the right to dividend). Because the index measures the cumulative value of dividends paid in a given calendar year, therefore it is reset to zero after the market close on the third Friday of December (in connection with index futures and options expiration in December).
