In 1990, the Community of Portuguese Language Countries (CPLP), which included representatives from all countries with Portuguese as the official language, reached an agreement on the reform of the Portuguese orthography to unify the two standards then in use by Brazil on one side and the remaining Portuguese-speaking countries on the other. This spelling reform went into effect in Brazil on 1 January 2009. In Portugal, the reform was signed into law by the President on 21 July 2008 allowing for a 6-year adaptation period, during which both orthographies co-existed.
