With four months to go before the end of the University’s Aspire fundraising campaign, campaign leaders told guests at the Alumni Day luncheon they are confident that the $1.75 billion goal will be met by June 30.

Robert Murley ’72, co-chairman of the campaign, said that more than $1.65 billion had been raised as of Feb. 25. With Annual Giving on track to reach its $53 million target, he said, the University needs to raise an additional $70 million in capital gifts to complete the campaign.

Nancy Peretsman ’76, who is leading the campaign along with Murley, said more than 75 percent of all undergraduate alumni have contributed since the launch of the campaign.

For fiscal 2011, Princeton ranked 25th in charitable contributions among U.S colleges and universities with $236.2 million, according to a Feb. 15 report of the Council for Aid to Education.
