Demand from international institutional investors on the euro tranches has been equal to almost 80% of the overall demand.

Thanks to hedging operations that covered exchange rate risks via interest rate swaps, for a notional amount of 5 billion euros, Enel was able to neutralize completely the significant interest rate hike over the last three months.
