The euro zone aims to leverage its 440 billion euro (383 billion pound) bailout fund, the EFSF, several fold but finance ministers will only agree the details of how that will be done in November, according to a draft statement to be issued after a summit on Wednesday.

The statement, obtained by Reuters, says two options are being considered to leverage the fund, one involving it issuing risk insurance and the other built around it taking part in a special purpose investment vehicle. Both models could be deployed simultaneously, the draft statement said.

The Eurogroup of finance ministers will be asked to finalise the terms and conditions for how the EFSF will operate under the leverage schemes in November, the statement said.

In addition, it said the EFSF's resources could be further enhanced, possibly via cooperation with the International Monetary Fund.

The draft statement also called on Spain to do more to bring its budget into line, while praising it for the steps taken so far. A paragraph on Italy, which is under pressure to do more on pension and other reforms, was left blank but is expected to be added later.
