The Schulz School of Business Administration (SSBA) is planning its annual commencement ceremony, to be held in the university's indoor arena. The university has granted SSBA use of this facility for 6 hours start- ing at 11 a.m., just after the School of Engineering holds its commencement In the same arena.
