BOSTON – Many Baby Boomers are not turning to financial advisers when it comes time to roll over their 401(k) assets at retirement, according to one recent study. Eighty-four percent of people ages 55 to 70 who have incomes above the $100,000 mark use financial advisers but only 30% do so when they roll over assets once they leave their jobs, according to a study from Bain & Co., a Boston-based business consulting firm. The study revealed that these Baby Boomers, who are persons born between 1946 and 1964, choose to make rollover decisions on their own. They're also choosing to spend more of their time looking for other financial products to buy at the time. Bain received 415 responses from people between the ages of 55 and 70, who are less than 10 years away from retirement and with an average income of $100,000. The group had an average $450,000 in retirement assets and $300,000 in non-retirement assets.
