“Education, religion, learning and research”, which are what the College exists to further, are not activities that pay for themselves, and in the nature of things those pursuing them are rarely if ever able to meet all the cost of doing so. Over the centuries the College has relied on three sources of income. First charges it levies for services it provides – fees, room rents, catering and conference charges. Secondly investment income from its endowment. And thirdly, income from investments held on trust for specific purposes such as providing scholarships and bursaries.
