So far no one has stepped forward to help bail out the Florida Philharmonic, which needs to raise $20 million by Friday so it can stay in business. “The Philharmonic, which has run deficits ranging from $900,000 to $3.6 million each year since 1999, needs about $4 million right away, Lewis said. The orchestra can make its May 9 payroll but will run out of money before it can pay employees on May 23. ‘What is difficult for me as a potential donor . . . is to hear that the orchestra has been so badly managed before and now we should trust you to make a better orchestra.”
