The market value of a brokered CD purchased through your brokerage account will fluctuate and, at times, may show a potential market value of more or less than the price you paid or face value of the CD. However, if you hold a brokered CD to maturity, you'll get back the principal amount plus interest; these price fluctuations only come into play if you sell your CD before maturity.
Note that brokered CDs held to maturity do not auto-renew. You'll need to purchase another CD if you desire.
Merrill may maintain a secondary market in brokered CDs, although it's not obligated to do so. You may be able to sell your brokered CD before it matures, but the price you receive could be less than your original investment.
Early withdrawals of brokered CDs are generally not permitted. In limited circumstances, such as the death of the owner of the CD, early withdrawal may be permitted.
Some brokered CDs, known as callable CDs, are subject to early redemption by the issuing bank at its sole discretion. They may offer higher yields than noncallable CDs, which return their principal at the stated maturity date. Callable CDs offer higher yields due to your risk of having your principal returned early and needing to purchase a new CD in a lower-interest-rate environment.
Brokered CDs purchased through your Merrill account pay simple interest; that is, interest is not compounded.
