Another variation is whether, on set up, the fund already has some assets to immediately transfer (or seed) into it or not. Most primary funds (and all of those in the top 10 listed in Figure 10) are not seeded. But secondary funds, by their nature, are seeded. A fund that is initially seeded may not be closed. However, it may seek additional investments. Table 2 provides a brief overview of the main features of seeded and unseeded funds. If a fund is only partially seeded, some of the unseeded fund risks remain.
