The articles list both schools as losing the just over $12.41 million each would have received from conference television revenue. The two articles (one each for A&M and Mizzou) also allude to other considerations in the settlement agreements, as well. Before today, rumor has it that the amounts have been somewhere between $15-17 million per school, so there could be portions of the settlement agreements that weren't announced today or that don't involve the conference simply withholding revenue. Or those rumors were simply wrong.
I doubt we hear much more about this going forward as it seems like both sides just want to get away from each other. A&M is happy going to the SEC with Mizzou in tow and the Big XII has moved on with TCU and West Virginia both joining for the 2012 seasons in all sports. Now we just get to have endless arguments about whether Big XII schools (particularly those in Texas) should schedule A&M. I know I'm excited!
UPDATE: Chuck Carlton of the Dallas Morning News says the total out-of-pocket for A&M is $9.31 million. That has been confirmed by Jason Cook, the A&M VP of Marketing and Communications, on his twitter account.
