The Substitute Occupational Benefit Institution is a foundation which operates in collaboration with the Swiss federal government.
The foundation provides an alternative to private occupational pension funds. Vested benefits which are not collected by their owner are held by the foundation until their owner can be located.
The foundation also operates a number of pension schemes for self-employed individuals who would like to take advantage of the second pillar to save for retirement, but are not eligible to join a 2a occupational pension fund. Pension schemes for self-employed individuals are voluntary and fall under the pillar 2b category of retirement savings.
