(Repeat for additional subscribers) May 15 (Reuters) - (The following statement was released by the rating agency) Fitch Ratings has upgraded Repsol SA's Long-term Issuer Default Rating (IDR) to 'BBB' from 'BBB-'. The Outlook is Positive. A full list of rating actions is provided below. The upgrade reflects the successful monetisation of nearly all of the USD5.32bn in nominal value of guaranteed Argentine government bonds Repsol received as compensation for the expropriation of 51% of its former subsidiary YPF (B-/Negative) and YPF Gas and the receipt of USD1.3bn of proceeds from the sale of Repsol's remaining minority stake in YPF. Repsol's total cash proceeds received from the combined transactions are USD6.1bn, exceeding Fitch's rating guideline for an upgrade of monetising at least USD3bn of its guaranteed Argentine government bonds.
