MADRID (Standard&Poor's) Dec. 2, 2010--Standard&Poor's Ratings Services has placed its 'BB+' long-term term sovereign credit rating on the Hellenic Republic (Greece) on CreditWatch with negative implications (see "Greece 'BB+' Sovereign Rating Placed On CreditWatch Negative On Unveiling Of European Stability Mechanism Plan," published today on RatingsDirect on the Global Credit Portal). We believe that this could have a negative impact on the creditworthiness of the four Greek banks and one related international subsidiary that we rate, namely: National Bank of Greece S.A. (BB+/Negative/B) and its strategically important Bulgarian subsidiary United Bulgarian Bank A.D. (BB/Negative/B), EFG Eurobank Ergasias S.A. (BB/Negative/B), Alpha Bank A.E. (BB/Negative/B), and Piraeus Bank S.A. (BB/Negative/B). We expect to publish a more detailed analysis
