Effective in fiscal years beginning after December 15, 1992, public utilities having more than 500 employees shall begin accruing postretirement benefits other than pensions obligations for financial reporting purposes. For ratemaking purposes, the Commission will determine in general rate proceedings, on a case-by-case basis, the appropriate amount of the costs of postretirement benefits other than pensions to be recovered in rates. The monies recovered from ratepayers in an amount estimated to equal the costs of postretirement benefits other than pensions shall be placed in an external account, specifically maintained for the purpose of funding these benefits for current and future retirees, unless the utility demonstrates substantial savings to the ratepayers by not externally funding. The utility shall make regular, periodic deposits to the fund in a manner calculated to maximize fund earnings.
