"Mark Johnson, an executive at one of the world’s largest financial institutions, cheated his client out of millions and now he’s going to prison for it," Acting Assistant Attorney General John Cronan said in the release on Thursday. "This sentencing should serve as a warning to those who engage in crooked financial schemes."
Johnson was also ordered to pay a fine of $300,000, the Justice Department added.
According to evidence presented at trial, Johnson cheated the client out of millions of dollars by misusing information in scheme known as "front running," the Justice Department said.
The evidence showed that Johnson and the traders he supervised generated $7.3 million in profits from the transaction, including profits from the front-running conduct.
On October 23, 2017, a federal jury convicted Johnson on one count of wire fraud conspiracy and eight counts of wire fraud.
