(a) Post Judgment Interest. Except as otherwise ordered by the court or provided by law, judgments, awards and orders for the payment of money, taxed costs and counsel fees shall bear simple interest as follows:
(i) For periods prior to January 2, 1986, the annual rate of return shall be as heretofore provided by this rule, namely, 6% for the period prior to April 1, 1975; 8% for the period between April 1, 1975 and September 13, 1981; and 12% for the period between September 14, 1981 and January 1, 1986.
(ii) For judgments not exceeding the monetary limit of the Special Civil Part at the time of entry, regardless of the court in which the action was filed: commencing January 2, 1986 and for each calendar year thereafter, the annual rate of interest shall equal the average rate of return, to the nearest whole or one-half percent, for the corresponding preceding fiscal year terminating on June 30, of the State of New Jersey Cash Management Fund (State accounts) as reported by the Division of Investment in the Department of the Treasury.
(iii) For judgments exceeding the monetary limit of the Special Civil Part at the time of entry: in the manner provided for in subparagraph (a)(ii) of this Rule until September 1, 1996; thereafter, at the rate provided in subparagraph (a)(ii) plus 2% per annum.
Post-judgment interest may be included in the calculation of an attorney's contingency fee.
(b) Tort Actions. Except where provided by statute with respect to a public entity or employee, and except as otherwise provided by law, the court shall, in tort actions, including products liability actions, include in the judgment simple interest, calculated as hereafter provided, from the date of the institution of the action or from a date 6 months after the date the cause of action arises, whichever is later, provided that in exceptional cases the court may suspend the running of such prejudgment interest. Prejudgment interest shall not, however, be allowed on any recovery for future economic losses. Prejudgment interest shall be calculated in the same amount and manner provided for by paragraph (a) of this rule except that for all periods prior to January 1, 1988 interest shall be calculated at 12% per annum. The contingent fee of an attorney shall not be computed on the interest so included in the judgment.
