Limbaring, who worked at the Southern California complex from 1995 to 2005, was accused of stealing cash that she was supposed to deposit in the bank on behalf of the center, and altering records to make it appeared that the money had been deposited properly.
She initially denied the charges, but later entered a guilty plea. She could have faced up to 19 years in prison on charges of grand theft, embezzlement, and computer fraud.
Limbaring has been ordered to return the money, but has only about $30,000 in assets. Much of the money she stole was gambled away, the Register says.
According to the paper, the fraud was the largest perpetrated on an American charity in a decade.
The Orange County Performing Arts Center hosts performances by the Pacific Symphony and Opera Pacific, as well as jazz, Broadway shows, dance, and other events.
