The appellants were former members of the Tongaat-Hulett Defined Benefit Pension Fund. In 2012, the Fund apportioned and distributed actuarial surplus amounting to R363.2 million to an employer surplus account in terms of Rule 11.5.4.1 of its Rules, following a rule amendment approved by the Registrar of Pension Funds. This apportionment formed part of a broader composite conversion and restructuring scheme approved under section 14 of the Pension Funds Act, in terms of which the Fund’s obligations to the appellants and other pensioners were outsourced to Old Mutual with effect from 1 April 2013, terminating their membership. The appellants challenged the surplus apportionment as unlawful, first before the Pension Funds Adjudicator and then on appeal to the High Court and the Supreme Court of Appeal.
