Carry, the core incentive mechanism of private equity funds, embodies the relationship among fund investors (GP), investors (LP) and GP. The most common mode is "2%+20%", that is, LP pays 2% management fee to GP every year during the investment period of a fund; After the expiration of the duration, GP can also share 20% of the profits after the principal is returned to LP after the fund returns to the pre-agreed bottom line. This 20% is a carry.
