Risks & Disclosures

All investments carry some degree of risk that will affect the value of the Fund’s holdings, its investment performance and the price of its units. As a result, loss of money is a risk of investing in the Fund. STIF is subject to the following principal investment risks: market risk, investment style risk, security specific risk, credit risk, interest rate risk, liquidity risk and prepayment risk.

Historical returns are not indicative of future performance. For further discussion of the Fund’s investments strategies and risks, please refer to the Investment Funds Description – P Series. This is not an offer to purchase securities.

Lending of Portfolio Securities

The Fund seeks to earn additional income by lending a portion of its portfolio securities to brokers, dealers and other financial institutions. The loans are secured at all times by cash and liquid high-grade debt obligations. As with any extension of credit, there are risks of delay in recovery and in some cases even loss of rights in the collateral should the borrower fail financially. In addition, losses could result from the reinvestment of the cash collateral received on loaned securities.

Expense Ratio

All expenses of STIF are deducted from STIF’s net asset value. The expenses include investment management fees, operating expenses, bank custodial fees and miscellaneous fund administration expenses. The expenses are paid by STIF and are reflected in the unit price calculated for the Fund. The unit price is multiplied by the number of units held in each client’s account to determine the total value of the client’s holdings in the Fund. For 2019, STIF’s expenses were equal to 0.33% of the Fund’s total assets.
