A UITF (or Unit Investment Trust Fund) is an open-ended pooled trust fund denominated in pesos or any acceptable currency, which is operated and administered by a trust entity. Each UITF Fund is governed by a Declaration of Trust (or Plan Rules) which contains the mechanics for investing, operating, and administering the fund. The funds are then invested by a team of professional portfolio managers in various other deposits and securities. Individuals and institutions take part in the UITF by purchasing units of participation in the fund.
