WisdomTree Investments Inc. has developed a 401(k) plan investment package for sponsors that want to emphasize use of index funds and exchange-traded funds.

WisdomTree, New York, says the program allows employers to include no-load, actively managed mutual funds as well as ETFs.

CLS Investment Firm L.L.C., Omaha, Neb., is handling asset-allocation services for the program.

Professional Capital Services L.L.C., Philadelphia, is in charge of participant recordkeeping, and an affiliate of TD Ameritrade Inc., Omaha, Neb., will be responsible for custody and trading services, WisdomTree says.
