NEW YORK (AP) – Adelphia founder John Rigas and his son, Timothy J. Rigas, were ordered Wednesday to report to prison on Aug. 13 for their fraud convictions.

In May, the 2nd Federal Circuit Court of Appeals in Manhattan upheld the convictions of the 82-year-old Rigas and his son on charges of securities fraud, conspiracy to commit bank fraud and bank fraud. Both have been free on bail.

John Rigas was sentenced to 15 years in prison, and Timothy Rigas, the company’s former chief financial officer, was sentenced to 20 years. The sentencing judge, citing the elder Rigas’ poor health, said the term might be cut short if he serves at least two years. Prison doctors believe he has less than three months to live.

At trial, prosecutors said the Rigas family used the company as their personal piggy bank, withdrawing millions of dollars to finance everything from 100 pairs of bedroom slippers for Timothy Rigas to more than $3 million to produce a film by John Rigas’ daughter. Prosecutors said John Rigas once even spent $6,000 to fly two Christmas trees to New York.

Last year, another son, Michael Rigas, was sentenced to 10 months of home confinement after pleading guilty to a charge of making a false entry in a company record.

Adelphia, based in Coudersport, Pa., was the country’s fifth-largest cable television company serving more than 5 million customers in 31 states. It collapsed into bankruptcy in 2002 after the company disclosed $2.3 billion in off-balance-sheet debt.

Comcast Corp. in Philadelphia and Time Warner Cable, a unit of Time Warner Inc., have since bought Adelphia’s cable assets.
