Argentina's President Cristina Fernandez de Kirchner sits next to Buenos Aires City Mayor Mauricio Macri (L) as they attend a ceremony at the Buenos Aires Stock Exchange August 2, 2012. The Argentine government announced the final payment of nearly $2.2 billion, which will be effective on August 3, that marks a watershed in Argentina's efforts to leave behind the huge sovereign debt default of 2002 and will reduce its already-low foreign currency debt burden.
