The total is 7 percent higher than last year's tally, and the highest ever for the orchestra. The funds will be split between the ISO's operating budget and its endowment.
"The people of Indianapolis have truly stepped up this year to show that they value the Orchestra as a part of the community," orchestra president Richard P. Hoffert said in a statement.
Hoffert added that the orchestra intends to boost its endowment in order to limit dependence on annual contributions.
The ISO posted deficits of $284,000 and $545,000 in 2002 and 2003. According to a spokesman for the orchestra, the orchestra has not completed its accounting for the 2004 fiscal year, which ended on August 31, but expects a healthier bottom line.
