New Jersey Statutes Title 43. Pensions and Retirement and Unemployment Compensation 43 § 8A-19

(1) All of the assets of the pension fund shall be credited according to the purpose for which they are held to one of three funds, namely the annuity savings fund, the pension accumulation fund, and the retirement reserve fund.

(2) The annuity savings fund shall be a fund in which shall be accumulated contributions from the compensation of members to provide for their annuities and additional death benefit coverage under section thirteen of this act.  1 The aggregate contributions of a member withdrawn by him or paid to his estate or his designated beneficiary in event of his death as provided in this act  2 shall be paid from the annuity savings fund. Upon the retirement or death of a member where the aggregate contributions and additional death benefit coverage under section thirteen of this act of the member are to be provided in the form of an annuity, the aggregate contributions of the member shall be transferred from the annuity savings fund to the retirement reserve fund.

(3) The pension accumulation fund shall be the fund in which shall be credited contributions made by employers. Upon the retirement or death of a member the reserve of any pension and death benefit under any section of this act other than section thirteen payable to or on his account shall be transferred to the retirement reserve fund. All interest and other income from investments shall be credited to the pension accumulation fund and annually the board of trustees shall transfer from the pension accumulation fund to the retirement reserve fund regular interest on the mean amount in the retirement reserve fund for the year. The board of trustees, in its discretion, may transfer to and from the pension accumulation fund any surplus or deficit in the retirement reserve fund.

(4) The retirement reserve fund shall be the fund in which shall be held the reserves on all retirement allowances and death benefits granted to members or their beneficiaries and from which all benefits in lieu thereof shall be paid. Should a member who retired on account of disability be restored to active service his pension reserve shall be transferred from the retirement reserve fund to the pension accumulation fund and the excess of his aggregate contributions as they stood at retirement over the amount of annuity payments made shall be transferred to the annuity savings fund.
