5.1 For the purposes of this Part,

• (a) despite paragraph 9(4)(c) of the Pension Benefits Standards Regulations, 1985, if there is a solvency deficiency, a plan shall be funded in each plan year by annual solvency special payments equal to the amount by which the solvency deficiency divided by 5 exceeds the amount of going concern special payments — other than those referred to in paragraph 12(1)(c) — that are payable during the plan year; and

• (b) “unfunded liability” means

  • (i) the going concern deficit of a plan as determined on the date that the plan was established;

  • (ii) the amount by which an increase in the going concern liabilities of a plan resulting from an amendment to the plan exceeds the going concern excess of the plan as determined on the day before the effective date of the amendment; or

  • (iii) the amount by which the going concern deficit of a plan determined at the valuation date exceeds the sum of

    • (A) the present value of going concern special payments established in respect of periods after the valuation date, and

    • (B) the present value of special payments referred to in paragraph 12(1)(b).

• 6. (1) Despite subsection 9(4) of the Pension Benefits Standards Regulations, 1985, an initial solvency deficiency of a plan may be funded in accordance with Part 1, but the remittance to the pension fund of a portion of the special payments determined under that Part may be deferred as if the initial solvency deficiency were funded by special payments sufficient to liquidate the initial solvency deficiency by equal annual payments over a period not exceeding 10 years from the day on which the initial solvency deficiency emerged.

• (2) The initial solvency deficiency may be funded in accordance with this Part only if less than one third of the members and less than one third of the beneficiaries excluding members object before the date indicated in the statement referred to in paragraph 8(1)(j).

• (3) Any objection expressed by a beneficiary representative on behalf of the persons that they represent shall be counted as a separate objection for each person that they represent.

• (4) Despite the fact that the special payments set out in subsection (1) may be made over a period that exceeds the period applicable under Part 1, for the purposes of subsection 8(1) of the Act, the amount by which the aggregate amount of special payments that would have been remitted to the pension fund in accordance with that Part from the day on which the initial solvency deficiency emerged, as adjusted to take into account the reductions in special payments resulting from the application of the Pension Benefits Standards Regulations, 1985, plus interest, exceeds the aggregate amount of special payments made to the pension fund in accordance with this Part, plus interest, shall be considered to be an amount accrued to the pension fund.

• (5) Interest shall be calculated by using the interest rate that was assumed in valuing the liabilities of the plan for the purpose of calculating the initial solvency deficiency.
