Incorrect Index Calculation for a number of Madrid based indices

Euronext has identified an issue affecting the calculation of certain Total Return and Decrement indices based on Bolsa de Madrid stocks, which are currently being incorrectly broadcast.

The real-time calculation of all Price indices remains correct.
