The decision, to be effective from Monday 12 June has been taken following a period of consultation with the financial markets.
The change will mean FTSE using the official closing prices for the Frankfurt exchange, which recently announced it was to extend trading until 20:00 CET (19:00 UK time).
The actual index official close calculation will therefore take place at 20:15 CET (19:15 UK time).
Following the meeting today of the FTSE Equity Indices Committee, any constituent changes to be carried out after the close of business on Friday 16 June will also include the official closing prices of Deutsche Borse.
Data vendors who currently receive information via LMIL should note they will be able to receive the extended hours information from MONDAY 26 June. In the interim, all relevant information will be made available in the usual way via FTSE product files, to be distributed from Monday 12 June between 19:30 and 20:00 hours UK time.
All on-going index values will be available on Reuters throughout the extended calculation period.
FTSE UK calculations, including the FTSE 100, will be unaffected by this decision.
Mark Makepeace, FTSE Managing Director said: “The extension of market hours at a number of European exchanges remains a key issue for large parts of the financial market. FTSE was keen to take account of the views of a broad range of market participants before reaching a decision.”
“It is only by constantly listening to and consulting with the market that FTSE is able to meet the needs of its customers across Europe.”
