Employers offering cash balance plans are likely to offer richer 401(k) retirement benefits than those with traditional pension plans, according to new data from Watson Wyatt Worldwide. The consulting firm studied 612 employers, including 489 with traditional plans and 72 with cash balance plans. All also offered 401(k)s. Those with cash balance plans made non-matching contributions to 401(k) plans that were more than twice as rich as companies with traditional plans, the data indicate. Companies with cash balance plans contributed 1.03% of pay in non-matching contributions to the 401(k) plans, compared with 0.5% for companies with traditional plans. And those with the cash balance plans contributed 3.02% of pay in matching 401(k) plan contributions, compared with 2.72% for those with traditional plans.
