Private equity funds can't say whether the income is high or not. It just allows everyone to raise funds in the form of enterprises, and then run by general partners. For the limited partner (you), just do it according to the income from signing the contract. I only know that there are some private equity fund contracts marked with guaranteed income. In this case, if something goes wrong, the general partner (the other party) will make up for it, and your rate of return will remain unchanged according to the contract.
