The Corner Team | The Panama Canal Authority and the  building consortium Grupo Unidos por el Canal (GUPC), led by Spanish construction company Sacyr, have both agreed to put up at at least $100 million each to keep the canal work running. The big question remains who should pay for $1.6 billion in cost overruns. GUPC has asked the canal administrator for a $400 million advance. Some Spanish analysts believe they’ll reach an intermediate agreement, in which the Panamanian Government covers half of the costs (circa $800 million), although the consortium would have to sacrifice some profit margin. The Spanish government insists they will not give money “in any case”.
