I thought it worked this way -
The fund has your money - they loan that out (invest) and the interest they get is higher than what they pay you - hence instant profit.
They do not need to borrow on top of what you have given them.
They may need a cash facility to provide funds to members who want to withdraw. That saves them buying and selling shares or recouping money they have invested. That is one reason to borrow.
Another is to gear up - to use your money as security to borrow more money. If they do that then it should be mentioned in the prospectus - at least I would expect so.
