With a MarketSafe CD, your deposited principal is always secure. At CD maturity, that's the least you get back.1 Of course, that would only happen if the CD's performance is not positive. Conversely, if the CD's performance is positive, you'll earn a market upside payment on top of your principal. The actual rules governing each CD’s performance and how the potential upside payment is calculated vary from CD to CD and are fully explained in each CD issue's term sheet.
