Paul S. Devine has been sentenced to one year in prison and $4.5 million fine for leaking some of the Apple’s secret to suppliers.

A former Apple executive who sold some of the iPhone maker’s secrets to suppliers will serve a year in prison and repay $4.5 million for his crimes.

Paul S. Devine was sentenced in San Jose federal court earlier this week, more than three years after he pleaded guilty to wire fraud, conspiracy and money laundering.

The U.S. Attorney’s office announced Devine’s penalty Friday, but declined to explain the reason for the lengthy delay in his sentencing.

Devine faced up to 20 years in prison.

The scheme funneled millions in kickbacks to Devine for passing along confidential information to Apple Inc. suppliers and manufacturers who used the secrets to negotiate more favorable deals.

Devine was a global supply manager at Apple from 2005 until his 2010 arrest.
