As described in the related pricing supplements for REML (the "REML Pricing Supplement"), FLGE (the "FLGE Pricing Supplement") and FEUL (the "FEUL Pricing Supplement"), Credit Suisse, as the issuer of REML, FLGE and FEUL (together, the "ETNs"), may, at its option, call or accelerate, as applicable, all issued and outstanding units of the ETNs. Credit Suisse has exercised this right by delivering a notice of issuer optional call and optional acceleration via the Depository Trust Company on December 10, 2021.

The call settlement date for REML is expected to be December 27, 2021. On the call settlement date, REML investors will receive a cash payment per ETN in an amount equal to the call settlement amount. The call settlement amount will be determined on the call valuation date of December 22, 2021 in accordance with the terms set forth in the REML Pricing Supplement, and will be calculated using an average of the index closing levels during the call valuation period and will include REML's stub reference distribution amount, if any, as of the call valuation date minus applicable fees. The five consecutive trading days beginning December 16, 2021 through December 22, 2021 will constitute the call valuation period. For more information about the call settlement amount, see "Key Terms—Call Settlement Amount" in the REML Pricing Supplement. Credit Suisse expects that NYSE Arca will allow REML to continue to trade until December 23, 2021. The REML coupon payment declared on December 2, 2021 is not affected by this announcement.
