3. For the purposes of section 39, Chapters X (Solvency and funding), X.1 (Appropriation of surplus assets) and XII (Division and merger), Division II of Chapter XI (Investments) and Chapter XIII (Rights of members and beneficiaries on winding-up) of the Supplemental Pension Plans Act (chapter R-15.1), the liabilities of a component and the corresponding account of the pension fund are considered to be separate from the liabilities and corresponding account of any other component.
However, where a pension plan has only one past component, the surplus assets of that component may be appropriated to the payment of employer contributions of the current component of the plan.
