BUENOS AIRES, Argentina, Dec. 21, 2010 /PRNewswire/ -- Standard and Poor's Ratings Services said last Friday it has raised IRSA Inversiones y Representaciones S.A.'s and its subsidiary Alto Palermo S.A.'s Corporate Credit Ratings on a Global Scale from B-/Positive Watch, to B/Stable, following the review of the business environment in the country and the upgrade of the Republic Argentina sovereign debt to B from B-. On the National Scale, for Argentina, the credit ratings for both IRSA and Alto Palermo were both raised from raA to raAA. Among other factors indicated in the local report, Standard and Poor's remarked the de-consolidation of Tarshop's business and IRSA's acquisition of Parque Arauco S.A.'s stake in Alto Palermo on one hand, and the issuance of the IRSA 2020 bond, on the other, as events improving the stability of cash flows and IRSA's debt structure, respectively.
