Neil,
I think here's your answer - this is a few years old though:
http://www.ncaa.org/releases/monthlyTele...Notes.html
The NCAA's revenues for fiscal year 2002-03 were approximately $438 million - 85% from television and media rights with another 10% from the sales of championship tickets. Expenditures for the same period were almost $428 million.
Of this amount 61% ($260 million) was directly distributed back to Division I member institutions and conferences, another 10% supported Division I championships, 7% went to Division II and III members and programs; 17% was expended on Association-wide programming such as catastrophic insurance for all student athletics, enforcement services, etc. The remaining 5% supported management and general expenses.
Six different methods are used to distribute these revenues. For the current fiscal year, the following distributions will be made during the April to August timeframe.
Academic Enhancement fund ($17.5 million) - Approximately $53,000 per Division I institution to be used for student-athlete programs and services.
Special assistance fund ($10.9 million) - Distributed to the conferences to meet emergency or essential needs for student athlete. Approximately 70 % is used for emergency travel and clothing.
Student-athlete opportunity fund ($19.2 million) intended for the direct benefit of student athletes based on conference guidelines.
Conference grants ($6 million) $195,000 to each Division I conference for support of 6 targeted areas.
Sports sponsorship ($35.1million) Institutions receive one unit worth approximately $17,600 for each sponsored sport above 13.
Grants-in-aids ($70.2) Allocations made based on the number of full-time equivalent grants the institution provides its athletes.
Basketball fund ($105.3) $140,964 per unit distributed based on the number of appearances in the Division I Men's Basketball tournament over a 6 - year period (1998 - 2003). These funds are primarily distributed through the conferences.
** These seven areas add up to about $264 million. This is close to the amount reported above ($260 million) that 'was directly distributed back to Division I member institutions and conferences' (as the article says).
