The move takes place as euro zone countries meet in Brussels in an attempt to stop the ongoing crisis. The two countries currently have a top-notch AAA rating from the agency. Standard and Poor’s said that 13 additional euro zone countries are also vulnerable to downgrade as a result of the continent’s economic crisis.
