A custodian in mutual fund is a trust company, bank, or similar financial institution that is responsible for holding and safeguarding the securities owned within a mutual fund. The custodian also records and reports all transactions to the fund manager. The custodian does not oversee the general administration, construct and manage the portfolio, or calculate the NAVPU of the mutual fund. These are the roles of other entities such as the fund administrator, the fund manager, and the fund accountant.

A passively managed fund is a type of investment fund that follows a predetermined strategy or rule to track the performance of a market index, such as the S&P 500, or a specific sector, such as technology or health care. A passively managed fund does not involve active decision-making by the fund manager, who simply replicates the composition and weighting of the index or sector. A passively managed fund aims to match the return and risk of the index or sector, rather than outperform it. A passively managed fund typically has lower fees and expenses than an actively managed fund, as it requires less research, trading, and oversight.
An exchange traded fund (ETF) is a type of passively managed fund that trades on a stock exchange like a common stock. An ETF holds a basket of securities that mirrors an index or sector, and its price fluctuates throughout the day based on supply and demand. An ETF allows investors to gain exposure to a diversified portfolio of securities with low costs, high liquidity, and tax efficiency.
A commodity pool is a type of investment fund that invests in futures contracts or options on commodities, such as oil, gold, or wheat. A commodity pool is usually actively managed by a commodity trading advisor (CTA), who uses various strategies to generate returns from the price movements of commodities.
A hedge fund is a type of investment fund that employs sophisticated and often aggressive strategies to achieve high returns and reduce risk. A hedge fund is usually actively managed by a hedge fund manager, who has wide discretion and flexibility to use various instruments, such as derivatives, leverage, short selling, arbitrage, etc. A hedge fund is typically available only to accredited investors who meet certain income and net worth criteria.
A labour-sponsored investment fund (LSIF) is a type of investment fund that provides venture capital to small and medium-sized Canadian businesses, while offering tax benefits to investors. An LSIF is usually actively managed by a labour union or an organization affiliated with a labour union, who selects the companies to invest in based on their potential for growth and job creation.

The nominal rate of return is the return before adjustment for inflation, which is given as 2%. The real rate of return would be adjusted for inflation (2% - 1.5% = 0.5%), but the question asks for the nominal rate. The feedback from the document states:
"It is important to consider the effects of inflation on investments because we can isolate the difference between nominal and real returns. Investors are more concerned with the real rate of return - the return adjusted for the effects of inflation. A nominal return is a return that has not been adjusted for the impact of inflation. The approximate real rate of return is calculated as: Real Return = Nominal Rate - Annual Inflation Rate."
