David Hurlic, Susanna Selesky, and others similarly situated sued Southern California Gas Company (SCGC) and the SCGC Pension Plan (Plan). Hurlic and Selesky alleged that a 1998 amendment of the Plan by SCGC violated the Employee Retirement Income Security Act (ERISA) and the California Fair Employment and Housing Act (FEHA).

The Plan provided participating SCGC employees with a defined benefit at retirement according to a benefit accrual formula. Before July 1, 1998, the Plan required participants’ retirement benefits to be calculated according to a “pre-conversion formula.”
