Dimensional 2045 Target Date Retirement Income Fund Institutional Class (DRIIX) is an open-end mutual fund managed by Dimensional Fund Advisors LP that seeks total return consistent with its current asset allocation, designed primarily for investors targeting retirement around 2045. The fund allocates its assets across a diversified portfolio of other Dimensional-managed mutual funds, including DFA U.S. Core Equity 1 Portfolio Institutional Class (approximately 29%), DFA U.S. Large Company Portfolio (approximately 28%), DFA Large Cap International Portfolio Institutional Class (approximately 11%), DFA Short-Term Extended Quality Portfolio Institutional Class (approximately 10%), DFA Two-Year Global Fixed Income Portfolio Institutional Class (approximately 10%), DFA Emerging Markets Core Equity Portfolio Institutional Class (approximately 7%), and DFA International Core Equity Portfolio Institutional Class (approximately 5%); this structure provides exposure to U.S. and non-U.S. equities, fixed income securities, and cash equivalents, with allocations systematically adjusted over time to reduce risk as the target date approaches. The fund operates within the target-date 2045 category, serving institutional investors with a low expense ratio of 0.22%, a large-blend equity style, medium credit quality, and limited interest-rate sensitivity, with total net assets of approximately $189 million as of late 2024.
Launched on November 2, 2015, and domiciled in the United States, the fund is headquartered in Santa Monica, California, with primary availability for sale in the U.S. market.
In February 2024, Dimensional Fund Advisors appointed Savina Rizova as co-chief investment officer alongside Gerard O’Reilly, with Rizova retaining her roles as investment research committee chair and global head of research; this leadership change did not alter the fund's Average People rating or contributing teams, though middle-dated portfolios like DRIIX continued to face headwinds from their longer duration profile amid rising rates through mid-2024.
