The chamber orchestra is known for its low ticket prices; half go for $15 or less. That’s partly thanks to two programs: With a Netflix-style membership, people can pay just $9 a month to attend unlimited concerts. And, since 2016, children and college students get in for free. About 19.8% of the nonprofit’s income in 2019 was “earned,” a category that includes ticket sales, down from 22.4% last year. About 62.8% of its income came from contributions from people, companies and foundations, up slightly. The other piece of the pie — $1.9 million this year — comes from the SPCO’s endowment. – The Star-Tribune (Mpls)
