Management refused to accept all counsel or advice on how to run the station, despite never turning a profit. Ultimately, AVG was forced into bankruptcy by Urban National on November 20, 1975 when it defaulted on promissory notes and warrants of around $400,000. Avant lost about $611,168.67 in the bankruptcy, $71,500 from Interior Music Corporation advances between August 1973 and September 1974, and $13,887 from Sussex Records loans. Comedian Bill Cosby was an additional investor in Avant Garde Broadcasting, investing approx. $200,000 through his company SAH Enterprises.
