Since the first addendum signed with Integración Energética Argentina SA (Ieasa, formerly Enarsa Argentina) in March 2010, gas sales to that country have fallen by up to 45%. According to the contract signed in 2006, Bolivia should export at least 23.5 billion cubic metres this year; however, with the fifth addendum, the volume of shipments reduced to 13.8 billion cubic metres.
