President Cristina Fernández de Kirchner of Argentina introduced a bill on April 16, 2012, for the partial renationalization of YPF, the nation's largest energy firm. The state would purchase a 51% share, with the national government controlling 51% of this package and ten provincial governments receiving the remaining 49%. The bill was overwhelmingly approved by both houses of Congress, and was signed by the president on May 5. The government of Argentina eventually agreed to pay $5 billion in compensation to Repsol, which had previously owned YPF.
