The character and kind of investments which may be made by the trustee depend on the investment parameters set forth in the UITF Declaration of Trust or Plan Rules. BSP Regulations, however, prescribe that UITF fund investments shall be limited to bank deposits, securities issued by or guaranteed by the Philippine government or the BSP, tradable securities issued by the government of a foreign country, any political subdivision of a foreign country or any supranational entity, exchange listed securities, marketable instruments that are traded in an organized exchange, loans traded in an organized market, such other tradable investments as the BSP may allow.
