ADMINISTRATIVE FEES: Fund expenses for keeping records, providing state-ments, processing transactions, ensuring the plan complies with applicable regulations, answering savers' questions, and providing customer service. Administrative fees generally range from 0.2 percent to 0.4 percent annually.7 ASSET MANAGEMENT FEES: Salaries for portfolio managers (who oversee different portions of a fund's assets), investment researchers, and the other employees responsible for fund's invest-ments. Asset management fees generally range from 0.5 percent to 1 percent annually.8 MARKETING FEES: Also called 12b-1 fees, these include the expense of informing savers and potential savers about the mutual fund, including advertisements, brochures, and other informational material. Increasingly, mutual funds are lumping together a number of other costs under the umbrella of 12b-1 fees, including rebates to 401(k) "recordkeepers"the companies that bundle various mutual funds into a 401(k) plan, sell it to mployers, and then keep the records for the savers in the 401(k)s. Marketing fees are limited to a maximum of 1 percent annually.9 TRADING FEES: The costs incurred by the fund when buying and selling the securities (bonds, stocks, etc.) that com-prise a mutual fund's underlying assets. The reasons why mutual funds trade their assets are several, and summarized in the box below. Each mutual fund pays a commission to a securities broker each time it buys or sells a security, and it loses small amounts of money on "bid/ask spreads" that represent the difference between the actual buy or sell price for a security and its market value. In other words, if the fund wishes to sell a security, it generally must do so at a price that is slightly lower than its market value, and vice versa. If a mutual fund sells large blocks of a security, it must often do so at a progressively lower price, increasing costs. These fees vary from year to year depending on both the number of shares of a mutual fund bought and sold in a year, and on the frequency with which fund managers buy and sell the securities that com-prise the underlying assets of the fund. Describe and detail all of the fees/costs associated with a 401(k). I need to summarize the above paragraph
