(A) that participant shall be charged with a contribution deficiency consisting of such unpaid amounts, together with interest thereon, compounded annually; and

(B) such interest on each amount of undeductible contributions shall accrue from the end of the payroll period for which such amount would have been deducted from compensation if he or she had been a participant at the beginning of that payroll period, until such amount is paid to the retirement system; and

(C) the rate of interest to be applied to each such amount during the period for which interest accrues on that amount shall be equal to the rate or rates of interest required by law to be used during that same period to credit interest on the accumulated deductions of retirement system members.

(ii) Except as provided in subparagraph (iii) of this paragraph, no interest shall be due on any unpaid additional contributions which are not attributable to the period prior to the first full payroll period referred to in paragraph two of this subdivision.

(iii) Should any person who, pursuant to paragraph seven of this subdivision, has withdrawn any additional member contributions (and any interest paid thereon) again become a participant in the twenty-five year/age fifty improved benefit retirement program pursuant to paragraph five of subdivision b of this section, an appropriate amount shall be included in such participant's contribution deficiency (including interest thereon as calculated pursuant to subparagraph (i) of this paragraph) as if such additional contributions had never been made. 4.

Where a participant has not paid in full any contribution deficiency chargeable to him or her pursuant to paragraph three of this subdivision, and a benefit, other than a refund of a member's accumulated deductions or a refund of additional member contributions pursuant to paragraph seven of this subdivision, becomes payable by the retirement system to the participant or to his or her designated beneficiary or estate, the actuarial equivalent of any such unpaid amount shall be deducted from the benefit otherwise payable. 7. (i) All additional member contributions required by this subdivision (and any interest thereon) which are received by the retirement system shall be paid into its contingent reserve fund and shall be the property of the retirement system.

(ii) Should a participant in the twenty-five year/age fifty improved benefit retirement program, who has rendered less than fifteen years of credited service cease to hold a position as a senior automotive service worker, automotive service worker, auto body worker, auto mechanic, marine maintenance mechanic or oil burner specialist for any reason whatsoever, his or her accumulated additional member contributions made pursuant to this subdivision (together with any interest thereon paid to the retirement system) may be withdrawn by him or her pursuant to procedures promulgated in regulations of the board of trustees of the retirement system, together with interest thereon equal to eight and one-quarter percent per annum, compounded annually.
