Former Adelphia Communications chief operating officer Michael Rigas will serve 10 months of home confinement and two years of probation for signing false documents that helped lead to the collapse of the cable company, a federal judge ruled Friday.

Mr. Rigas had faced three years in prison in connection with his guilty plea last November to reduced charges linked to an accounting scandal that ultimately led to Adelphia filing for bankruptcy in 2002. Mr. Rigas originally faced much stiffer prison sentences for his alleged role in the scandal, but the jury in the first trial deadlocked on most of the charges leveled against him.

Sentencing Mr. Rigas marks the final step in federal prosecutors’ effort to hold members of Adelphia’s founding Rigas family responsible for the company’s collapse.

John Rigas, Michael Rigas’ father and the founder of Adelphia, was sentenced last June to 15 years in prison. Another son, former chief financial officer Timothy Rigas, received a 20-year sentence.
