The controversy centers on 1Malaysia Development Berhad, called 1MDB, a government-controlled fund set up to pursue economic-development projects for Malaysia. Goldman arranged US$6.5b in bonds for the fund in 2012 and 2013, much of which US and Malaysian authorities now say was looted.
The stolen billions were spent on condominiums, paintings by Vincent van Gogh and Claude Monet, diamond jewelry and an US$250 million yacht, authorities say. Some of the money even went to funding the production of the movie "The Wolf of Wall Street."
"While we understand the anger and skepticism, we do not believe that the criticism directed at us accurately reflects who we were then or who we are now," Solomon said.
"We believe our culture and our processes around our due diligence and compliance was strong at the time, and is even stronger today."
Government authorities have also accused Goldman of securing the work with the help of bribes arranged by two former employees and others. Goldman then received higher than average fees, US$600m, for the work and its employees received bonuses, authorities say.
The fees were justified by the nature of the work, Solomon said in his message to employees.
"In fact, it took us almost a year to sell the bonds from the last offering because the market had turned against us," he said.
