(Bloomberg) — Fidelity Investments, the largest provider of 401(k) retirement savings plans, says average balances in the employer-sponsored accounts reached a record high in 2012 as market gains boosted assets.
The average U.S. balance rose 12% from 2011 to $77,300 as of Dec. 31, 2012, according to a report this month by the Boston-based mutual-fund firm. Fidelity administers plans for about 12 million workers and has been tracking the data since 2000.
