Louisiana Revised Statutes Tit. 11, § 3660. Minimum monthly pension established and cost-of-living increase

A. The board of trustees shall be authorized to use interest earnings on investments of the system in excess of normal requirements as determined by the actuary to provide an annual cost-of-living increase in benefits to be paid monthly for members who have retired in an amount not to exceed four percent of the original benefit for each year of retirement. Such benefits shall be paid only when funds are available from this source, or from funds appropriated for this purpose by the city of New Orleans, and payments shall be made in such manner and in such amount as may be determined by the board of trustees, based on funds available. This increase shall not be a part of the regular retirement benefit and shall not have the effect of reducing or replacing any supplemental benefit now provided by existing laws. The city of New Orleans may annually appropriate an amount sufficient to pay this supplementary benefit less any excess interest funds which may be available. Excess interest funds shall be earnings of the fund in excess of three and one-half percent per annum.

B. Effective August 1, 1972, the board of trustees is authorized to provide and pay a cost-of-living increase in benefits to members who retired on or before that date, said increase to be in an amount equal to two percent of the benefit being paid prior to such date, provided that such members be not self employed or otherwise gainfully employed with earnings in excess of two thousand four hundred dollars per year exclusive of social security taxes in so far as the additional two percent is concerned. This cost-of-living increase shall be in addition to the two percent increase previously provided for such retirees.
