The fund seeks to earn income through an actively-managed portfolio of primarily Canadian-listed preferred stocks. Such securities are concentrated in issuers in the financial services, utility, and energy sectors, and may have redemption, retraction, or conversion rights. The fund may also hold common shares, government and corporate bonds, and other income-producing securities. From time to time, TPRF may also invest in foreign securities but will not typically exceed 5% of its assets. In some market conditions, the fund may invest in short-term or other debt securities.
