Quarterly payments occur only if both underliers trade at or above a 70% downside threshold of their initial values on each determination date; automatic early redemption occurs if both underliers trade at or above their initial values on a determination date. If the final value of the worse performing underlier is below its 70% threshold, the maturity payment equals the stated principal multiplied by that underlier's performance factor and could result in a loss of more than 30% or the loss of the entire principal. Payments are unsecured obligations of Barclays Bank PLC and are subject to the issuer's credit risk and the exercise of any U.K. Bail-in Power. Pricing, actual contingent payment and initial underlier values will be set on the pricing date.
