Nancy Drew is the president of Mystery Capital Management, Inc. Mystery manages \($1.2\) billion in two mutual funds, one a stock fund and the other a bond fund. Competition for investors' money is fierce, and hundreds of money management companies compete by advertising their funds' performance statistics. The U.S. Securities and Exchange Commission has criticized the advertisements for misrepresenting the returns investors can actually earn. In addition to the investment performance statistics, money management firms also advertise the amounts of their fees, usually representing no-load or low-fee arrangements, but they often do not advertise the Rule 12(b) expenses allowed under SEC rules. Ms. Drew has retained your CPA firm to give an opinion on the fair presentation of Mystery Capital Management's investment performance statistics and expense ratios used in its advertisements. The plan is to present your report in the company's advertisements. Required: For each of the attestation standards, state its applicability in relation to the engagement.
