In the High Court in London on Tuesday, a former lawyer for the Libyan Investment Authority testified that the country’s sovereign-wealth fund was “astonished to learn” it hadn’t bought any actual shares through nine equity derivatives trades arranged by Goldman Sachs in 2008 that expired, worthless, three years later. The LIA is suing Goldman for $1.8 billion in losses.

On Monday, a lawyer for the Libyan Investment Authority told a British judge that employees of Goldman Sachs, attempting to win the $60 billion oil fund’s business, lavished executives with prostitutes and vacations at five-star hotels. The relationship fell apart in 2008, after Goldman lost the LIA $1.2 billion.
