The Tek Corporation Pension Fund, a defined benefit fund, accumulated a substantial actuarial surplus which relieved the employer, Tek Corporation, of the obligation to contribute further (a so‑called 'contribution holiday'). Many employees later transferred to a newly established defined contribution provident fund. Despite the transfers, a surplus remained in the pension fund. The employer attempted to rely on that surplus to avoid making contributions to the provident fund. Following a corporate sale, former Tek employees who became members of the Malbak provident fund claimed that part of the surplus should follow them. The trustees and employer denied any employee entitlement to the surplus, asserting it lay under employer control. Mr Lorentz, a former member, sought declaratory relief regarding the lawful use of the surplus.
