The Sixth AP Fund also manages a degree of buffer capital but, unlike the other Swedish National Pension Funds, is an evergreen fund, which means that there are no regular payments to or withdrawals from the fund. Accordingly, profits can be reinvested, whereas losses must be covered by the fund capital. The investment regulations differ from those applying to the other buffer funds in that the Sixth AP Fund has the mission of investing in small and medium-sized Swedish growth companies, by direct or indirect ownership, thus contributing to the development of Swedish industry. At the inception of the Sixth AP Fund in 1996, it received an initial capital of SEK 10.4 billion.
