Experts: More Americans Will Work Past Age 65

But 75% of the survey participants believe at least one-third of individuals ages 65 to 74 will be working in 2010, and about 75% of the participants said they believe that most people who work after age 65 will continue to save for retirement.

Although traditional defined benefit pension plans will continue to lose ground to 401(k) plans and other defined contribution retirement plans, institutional money managers will make up for lost pension assets by capturing more 401(k) plan assets, according to the survey participants.

By 2010, institutional funds will manage 21% of all 401(k) plan assets, the participants said.
