GDF SUEZ has launched a CHF 300 million bond issue

Today, GDF SUEZ has successfully launched a CHF 300 million bond issue. The bond has a 6-year maturity and carries a 1.5% coupon. GDF SUEZ has taken advantage of current favorable conditions on the Swiss Franc bond market. This emission has been swapped into Euro at fixed rate at 2.99% fixed rate, an historically low level of interest rate and currently more attractive than a straight bond issue in Euro.

This opportunistic issue is in line with the dynamic financing policy of the Group and helps to further diversify its financing. This transaction once again illustrates the market confidence in the prospects of the Group.
