Class A mutual fund shares typically include a front-end sales charge, also called a front-end load. The investor pays this charge at the time of purchase, and it is included in the public offering price. The public offering price equals the net asset value plus the applicable sales charge. Choice B is correct. A back-end load or contingent deferred sales charge is more commonly associated with Class B shares or certain other share classes, not the defining cost element of Class A shares. Choice C is incorrect because mutual funds use forward pricing; orders are priced at the next calculated net asset value after the order is received, not the prior day’s NAV. Choice D is also incorrect because the relevant price is the next calculated NAV after receipt of the order, not necessarily the following day’s close. The SIE outline includes open-end funds, share classes, net asset value, loads, sales charges, and costs and fees. This question tests both mutual fund share-class structure and the distinction between front-end and deferred sales charges. Reference: Section 2.1.4 Packaged Products.
