TORONTO — Two former Broadway producers were convicted yesterday of participating in large-scale accounting fraud, after a judge found they overstated their company’s finances for several years.

Garth Drabinsky and Myron Gottlieb, co-founders of Livent, a major Broadway theater company in the 1990s that produced hit shows such as “Ragtime” and “Showboat,” were convicted of two counts of fraud and one count of forgery.

In the 85-page ruling, the judge said Drabinsky and Gottlieb knowingly submitted financial statements to investors misrepresenting their company’s circumstances from 1994-1998.

Livent filed for bankruptcy protection in 1998 after the fraud was revealed.
