TIAA Investments has something to crow about—it's just been named by Lipper as the best overall large fund company for the fourth year in a row.

The Lipper Fund Awards single out for notice the funds and fund management firms that have excelled in providing consistently strong risk-adjusted performance relative to their peers. Classifications of three-, five-, and 10-year periods, as well as fund families with high average scores for the three-year period, are recognized.

TIAA Investments demonstrated the best three-year risk-adjusted performance across multiple asset classes among 37 mutual fund families. It also received the U.S. Lipper Fund Award for best mixed-assets large fund company, coming in at the top of 39 mutual fund families eligible for the award—which was based on the three-year risk-adjusted performance for its lifecycle, lifecycle index and lifestyle and managed allocation funds.
