A Swiss banker pleaded guilty to fraud for helping an unnamed hedge fund manager and other US taxpayers hide $60 million in assets.

Daniel Walchli, who worked at Zurich’s Privatbank IHAG, entered his plea Thursday to a single count of conspiracy to defraud the US. The charge carries a maximum sentence of five years in prison, but Manhattan federal prosecutors agreed not to seek a punishment outside of 24-to-30 months.
