A former business titan convicted in a notorious corporate fraud case is now board chairman of a nonprofit that helps ex-prisoners.

The Fortune Society announced Tuesday that ex-Tyco International CEO L. Dennis Kozlowski was elected to the post. The group helps about 4,500 ex-prisoners re-enter society every year.

Kozlowski and another Tyco executive were convicted in 2005 of looting the security systems company of $600 million.

The trial featured headline-grabbing tales of lavish spending, including a $6,000 shower curtain.

Prosecutors also detailed a $2 million toga party he threw on the Italian island of Sardinia in 2001 — complete with an ice sculpture of Michelangelo's "David" urinating vodka.

Kozlowski served 6½ years behind bars.

Kozlowski says he's humbled and inspired by those at the Fortune Society.
