DFIP is part of a suite of the first active fixed income ETFs offered by Dimensional. It is the ETF version of a mutual fund that the issuer made available a couple of years earlier. DFIP seeks to earn current income while providing protection from inflation. The portfolio primarily consists of inflation-linked securities issued by the US government and its agencies, including Treasury Inflation-Protected Securities (TIPS). The fund typically buys securities with maturities between 5 and 20 years from the settlement date and considers an average duration similar to its benchmark, the Bloomberg U.S. TIPS Index. To gain the desired exposure, the fund adviser may also use futures and options.
