A utility may seek a waiver from the Commission that permits the utility to use a method of its own design which combines the effects of SFAS 106 accounting and funding with the effects of accounting for and/or funding of its pension plan, provided such mechanism is the least-cost option, is beneficial to its ratepayers, is legal under applicable pension and benefit laws, and is permissible under GAAP and the accounting rules of this Commission.
The utility may seek a waiver of any Commission accounting rule to the extent necessary to implement such a mechanism. Any utility requesting authorization to use a combined pension/OPEB mechanism must submit its request in writing.
