All brokered CDs may fluctuate in value between purchase date and maturity date. CDs may be sold on the secondary market, which may be limited, prior to maturity subject to market conditions. Any CD sold prior to maturity may be subject to a substantial gain or loss. Vanguard Brokerage does not make a market in brokered CDs. The original face amount of the purchase is not guaranteed if the position is sold prior to maturity. CDs are subject to availability. As of July 21, 2010, all CDs are federally insured up to $250,000 per depositor, per bank. In determining the applicable insurance limits, the FDIC aggregates accounts held at the issuer, including those held through different broker-dealers or other intermediaries. For additional details regarding coverage eligibility, visit fdic.gov External site. Vanguard Brokerage imposes a $10,000 minimum for CDs purchased through Vanguard Brokerage. Yields are calculated as simple interest, not compounded. Brokered CDs do not need to be held to maturity, charge no penalties for redemption, and have limited liquidity in a secondary market. If a CD has a step-rate, the interest rate of the CD may be higher or lower than prevailing market rates. Step-rate CDs are subject to secondary-market risk and often will include a call provision by the issuer that would subject the investor to reinvestment risk. The initial rate of a step-rate CD cannot be used to calculate the yield to maturity. If a CD has a call provision, the issuer has sole discretion whether to call the CD. If an issuer calls a CD, there is a risk to the investor that the investor will be forced to reinvest at a less favorable interest rate. Vanguard Brokerage makes no judgment as to the creditworthiness of the issuing institution and does not recommend or endorse CDs in any way.
