NEW YORK ( TheStreet) -- Minneapolis, Philadelphia, Syracuse, Louisville, Albuquerque, Honolulu -- since 2008, each of those cities has been shaken by the financial troubles of its nationally known orchestra. Lately the Brooklyn Philharmonic Symphony Orchestra has joined those ranks. According to a source close to the Brooklyn group, "the orchestra is in serious financial difficulty and the board is exploring options including a merger and an infusion of funding." From all evidence, the picture appears even more bleak. For now, no contracts with venues or with the group's celebrated artistic director, Alan Pierson, have been renewed for the 2013-14 season, the group's Web site has been taken down and its offices are not staffed. WQXR first broke this story in a series of articles last week. There are similar problems with opera companies. Notably, in a story TheStreet documented, the New York City Opera suffered a very public financial crisis and humiliating end to its operations mid-season when a proposed fund-raising campaign sputtered and died at an early Kickstarter stage. Orchestras and classical music organizations in general are not transient. Some have limited tours, some even depend on touring. But most are tied to a particular place, even a particular venue, and help raise generation after generation to new levels of culture, acting as schools and as dynamic symbols of the best we can do. As they fail, that identity is chipped away; the best we can do becomes just a little less. The trend may have something to do with a flagging popularity of classical music. But there are two big flaws in that casual observation. First, listening trends at least indicate that, if anything, classical music's audience is growing. Second, orchestras don't necessarily limit themselves to classical music. There are, however, trends in the way the groups function that can lead to such an epidemic. These groups are all nonprofit organizations with, on the whole, very little money held in reserve. Operating income consists almost entirely of ticket sales, which almost never entirely cover a group's expenses. That leads to predictable problems. "I know of no orchestra in the world that carries an operating surplus," said author and Stanford University Professor Emeritus of International Labor Economics and Policy Analysis Robert Flanagan. "Worse, operating deficits increase over time." The way orchestras fill that gap is through a combination of private and government support. That government support may take the form of direct sponsorship, through grants from the National Endowment for the Arts or through state organizations, or it may come indirectly through tax incentives that bolster charitable giving. In Flanagan's research, documented in his 2012 Yale University Press book, The Perilous Life of Symphony Orchestras: Artistic Triumphs and Economic Challenges, the reliance of direct sponsorship from the government has dropped dramatically in the last 30 years, hovering now below 4% of revenue for most orchestras. At the same time, the rise of the music over the Internet has helped undermine ticket sales. Subscriptions in particular, historically the lifeblood of performing organizations, have fallen through the floor, forcing groups to rely more on guesswork when it comes to estimating revenue for a season. With those elements in place, the Great Recession worsened the situation by cutting into revenue from charitable contributions. Many high-net-worth individuals, who account for most charitable giving, budget their giving from their investment income. During the recession, that income took a major hit and individual giving dropped. Giving USA, a group that monitors charitable giving, finds that national charitable contributions to the arts and culture fell 8.2% during the two-year recession of 2008 and 2009 from a high of $13.7 billion in 2007. While it has increased since then, it remains below pre-crisis levels when adjusted for inflation. The Brooklyn Philharmonic gets more from government grants than most orchestras, but that was still insufficient to stop the pinch of the recession. "We have four sources for contributions: foundations, government, individual and corporate. All four fell dramatically," the orchestra source said. "It had a huge impact on us." While it continued with smaller events and outreach, the group held no full orchestra concerts for two seasons, from 2009 to 2011. In 2011, a new administrator, Richard Dare, and new artistic director, Alan Pierson -- a young conductor and director of the New York-based new music ensemble Alarm Will Sound -- gave the Brooklyn Phil a new lease on life. Dare's aggressive leadership, including a flashy presence as a blogger on cultural business issues with the Huffington Post, seemed perfect for the orchestra's challenges, both in fundraising and in cultivating an audience among the diverse and changing communities of Brooklyn.
