unrelated business income

can somebody write 1-2 examples of unrelated business income? I know is taxed, but to be honest I am not very sure of what unrelated business income is… thanks a lot

it is unrelated to the normal charitable income, ie selling concert tickets held by by the college is regarded as non-charity related income. ie any income derived from commercially related activities that charities are not suppose to engage in.

is this for foundation/endowment? - sticky

There was an example of UBI on one of the CFAI exams, i believe 2004

I remember an question where the Plan (not sure which one, perhaps a foundation) owned a private firm. The income from this firm was unrelated business income.
