The three types of MPF schemes are:

Master Trust Schemes: The most common type of MPF schemes, open to relevant employees of participating employers, self-employed persons and persons with accrued benefits transferred from other schemes. By pooling together contributions from various employers and their relevant employees, and those from self-employed persons, master trust schemes have a high degree of efficiency in terms of scheme administration because of economies of scale.

Employer-sponsored Schemes: Membership of this type of schemes is limited to relevant employees of a single employer and its associated companies. Because of this, it is only cost-effective to run an employer-sponsored scheme if the number of employees is large.

Industry Schemes: Schemes specially established for employees of the catering and construction industries, where there are high labour mobility and turnover. If you are an employee in these industries, and you are a member of such a scheme, you do not need to change schemes if you change your job within these two industries, so long as your previous and new employers are both participating in the same industry scheme.
