Description: This report presents the results of a survey conducted for the Society of Actuaries Pension Section Research Committee by Mathew Greenwald & Associates, Inc, March 2005. The purpose of the survey was to examine the prevalence of traditional and hybrid defined benefit pension plans in large organizations that have operations in the United States. The results of the study may prove useful to pension practitioners and policy makers wishing to gauge the effect of a recent US court ruling with potentially widespread implications for pension plans commonly referred to as cash balance plans.
