The university retains its right to use the land for its "research, education and engagement mission" in perpetuity. The university's share was $111 million or 52%. TCF Financial Corporation of Wayzata is contributing $35 million over 25 years in exchange for the naming rights and other agreements. The university projected earnings of $2.5 million per year or $96 million over the life of agreements with TCF that will include marketing debit cards to alumni and ticketholders. If unable to fulfill its contractual obligations, TCF Financial Corporation must propose an alternate name subject to the approval of the university. Other corporate donations have been pledged as well, including Best Buy ($3 million), Dairy Queen ($2.5 million), Target Corporation ($2 million), Federated Insurance, General Mills, and Norwest Equity Partners. The university also accepts donations from individuals. Initially donations were only being sought from "high-end" donors (those contributing $100,000 or more), but in June 2008 the university expanded the fundraising effort to gather smaller donations as well. On May 21, 2009, the University announced they had received a $6 million donation from T. Denny Sanford, meaning the university had achieved its goal of $86 million in private fund raising. The remainder of the university's portion will come from a $12.50 per semester student fee ($25 per year) and game day parking revenue. Even though the cost of building TCF Bank Stadium originated at $248.7 million, changes in the construction planning raised the cost to $288.5 million. The university has vowed that even if the stadium cost rises again, it will not seek more money from the state nor increase the student fees any further. The University has been charging all U of M students a mandatory stadium fee of $12.50 every semester since planning for the project began, and is continuing this fee despite the stadium being finished. The cost of the stadium was $288.5 million of which the university had to pay 52%, and with an average of more than 50,000 students in a given year, in one semester the university makes more than $625,000 from the stadium fee, meaning they receive more than $12.5 million every 10 years from students. The Shakopee Mdewakanton Sioux Community (SMSC) agreed to donate $10 million for stadium construction, the largest gift Gopher athletics has ever received. The university matched an additional $2.5 million to create a $5 million endowment for scholarships for Native American and low-income students.
