The protests achieved two of their stated goals. Columbia disaffiliated from the IDA and scrapped the plans for the controversial gym, building a subterranean physical fitness center under the north end of campus instead. A popular myth states that the gym's plans were eventually used by Princeton University for the expansion of its athletic facilities, but as Jadwin Gymnasium was already 50% complete by 1966 (when the Columbia gym was announced) this was clearly not correct. At least 30 Columbia students were suspended by the administration as a result of the protests. Many of the Class of '68 walked out of their graduation and held a countercommencement on Low Plaza with a picnic following at Morningside Park, the place where the protests began. The protests hurt Columbia financially as many potential students chose to attend other universities and some alumni refused to donate money to the school.
