Seventy-nine percent of 401(k) plans had a qualified default investment alternative at the end of 2007, the first year for QDIAs under the Pension Protection Act, with target-date funds the QDIA of choice, according to a Callan Associates survey. The survey didnt provide the specific number of plans with target-date funds. Nearly half (49%) that offer or anticipate offering a target-date or target-risk fund as the QDIA will use a mutual fund structure. Eighteen percent currently use or intend to use a custom mix of funds for their QDIA, up from 11% from last years QDIA Survey. Also, 44% offered automatic enrollment, with another 6% stating they were likely to add it in 2008. Callan surveyed 90 clients that are large plan sponsors.
