The canal’s fiscal year runs from Oct 1 to Sep 30.
The waterway posted record revenues despite a drop in the crossings during the 2007-2008 fiscal year, it said.
In February 2007, canal authorities had approved changes in the tonnage rules and classified tolls by type of ship as part of an effort to finance the waterway’s expansion plan.
The project is expected to cost around $5.25 billion after its completion in 2014, the report said.
