These two new indices have been developed to comply with the new EU regulations known as UCITS III, under which shares belonging to the same group may not make up more than 10% of the basket comprising the index, and the sum of the weightings of groups making up more than 5% of the index must not total more than 40%. As a result, the weightings that exceed these limits must be reduced to comply with the regulations, while others must be raised, so that the total reaches 100%. Ordinary rebalancing occurs four times a year, on the third Monday of March, June, September and December (at the same time as Borsa Italiana revises the composition of baskets in the case of the March and September dates). Extraordinary rebalancing occurs when the 10/40 limits are exceeded.
Comit Globale R 10/40 (base 02/01/2006 = 100) Comit Performance R 10/40 (base 02/01/2006 = 100)
In general Comit Globale R 10/40 only measures capital gains, and thus its value falls on payment of ordinary dividends since the reserves incorporated in the shares have been paid out. The Comit Performance R 10/40 provides a measure of total yield (dividends plus capital gains) as it includes the ordinary dividends distributed.
