Ex-divs to take 1.82 points off FTSE 100 on Oct. 9

LONDON, Oct 6 (Reuters) - The following FTSE 100 companies will go

ex-dividend on Thursday, after which investors will no longer qualify for the

latest dividend payout.

According to Reuters calculations at current market prices, the effect of

the resulting adjustment to prices by market-makers would take 1.82 points off

the index.

From Oct. 9, ex-dividend dates for stocks listed on the London Stock

Exchange will fall on the Thursday of each week, or one business day before the

dividend record. This is due to new European rules - dubbed 'T+2' - aimed at

reducing the time between executing a trade and settling its payment to two

days, rather than three.

Before the new regulation became effective, on Monday, ex-dividend dates

used to fall on Wednesday.
