The term setting of private equity funds can be divided into investment period, withdrawal period and extension period. For example, if the term of a fund is 5+2 years, then 5 years is the investment period and 2 years is the withdrawal period; The term of the fund is 3+ 1+ 1 year, so 3 years is the investment period, 1 year is the withdrawal period, and 1 year is the extension period. The extension period is mainly used to continue to deal with the legacy projects that failed to quit in the previous year. According to the nature of the fund, investment industry, investment projects and the situation of the capital market at the time of withdrawal, the term setting of the fund is also different.
