As with any business, running a mutual fund involves costs — including shareholder transaction costs, investment advisory fees, and marketing and distribution expenses. Funds pass along these costs to investors by imposing fees and expenses. It is important that you understand these charges because they lower your returns.

Some funds impose "shareholder fees" directly on investors whenever they buy or sell shares. In addition, every fund has regular, recurring, fund-wide "operating expenses." Funds typically pay their operating expenses out of fund assets — which means that investors indirectly pay these costs.

SEC rules require funds to disclose both shareholder fees and operating expenses in a "fee table" near the front of a fund's prospectus. The lists below will help you decode the fee table and understand the various fees a fund may impose:

Shareholder Fees

• Sales Charge (Load) on Purchases — the amount you pay when you buy shares in a mutual fund. Also known as a "front-end load," this fee typically goes to the brokers that sell the fund's shares. Front-end loads reduce the amount of your investment. For example, let's say you have $1,000 and want to invest it in a mutual fund with a 5% front-end load. The $50 sales load you must pay comes off the top, and the remaining $950 will be invested in the fund. According to the rules of the National Association of Securities Dealers, a front-end load cannot be higher than 8.5% of your investment.
   
• Purchase Fee — another type of fee that some funds charge their shareholders when they buy shares. Unlike a front-end sales load, a purchase fee is paid to the fund (not to a broker) and is typically imposed to defray some of the fund's costs associated with the purchase.
   
• Deferred Sales Charge (Load) — a fee you pay when you sell your shares. Also known as a "back-end load," this fee typically goes to the brokers that sell the fund's shares. The most common type of back-end sales load is the "contingent deferred sales load" (also known as a "CDSC" or "CDSL"). The amount of this type of load will depend on how long the investor holds his or her shares and typically decreases to zero if the investor holds his or her shares long enough.
   
• Redemption Fee — another type of fee that some funds charge their shareholders when they sell or redeem shares. Unlike a deferred sales load, a redemption fee is paid to the fund (not to a broker) and is typically used to defray fund costs associated with a shareholder's redemption.
   
• Exchange Fee — a fee that some funds impose on shareholders if they exchange (transfer) to another fund within the same fund group or "family of funds."
   
• Account fee — a fee that some funds separately impose on investors in connection with the maintenance of their accounts. For example, some funds impose an account maintenance fee on accounts whose value is less than a certain dollar amount.
