Job: Global finance management
Michael Kopper is the first Enron executive to admit guilt and pledge cooperation with federal prosecutors.
He has pleaded guilty to charges of money laundering and wire fraud, and has promised to pay back $12m of ill-gotten gains.
Most importantly, he is expected to spill the beans on Enron’s top bosses, allowing the prosecution to put together a stronger case.
Mr Kopper was right-hand man to Andrew Fastow, Enron’s disgraced chief financial officer who created the partnerships that artificially inflated profits.
An internal investigation by Enron found that Mr Kopper was closely involved in the partnerships and made considerable personal gain from them.
He faces a maximum jail sentence of 15 years, but his cooperation with prosecutors is likely to make the judge more lenient.
