COSI® are structured products with a minimal issuer risk. This protection is provided by means of a collateral pledge. Investors thus profit from increased protection on the invested capital. This unique service is offered by SIX Swiss Exchange in collaboration with SIX SIS and SIX Repo.

The investor who purchases a certificate assumes a default risk, also called an issuer risk. This varies according to the creditworthiness of the issuer and could result in a total loss for the investor in the event of the insolvency of the issuer. In order to minimize this risk, SIX is offering a service for the collateralization of certificates. This collateralization is based on the "Framework Agreement[pdf]" that the issuer and the collateral provider conclude with SIX Swiss Exchange and SIX SIS.

You can find more detailed information on the subject of collateralization here and on the participation conditions here.

Quality Seal

The seal of approval created by SIX Swiss Exchange represents the unique advantages and quality characteristics of COSI. Investors can quickly identify COSI products thanks to this clearly visible distinguishing mark. This seal enables issuers to highlight the internationally unique collateralization and high degree of legal certainty of their products, and market them in a more targeted manner - a classic win-win situation.

All issuers who conclude an agreement with SIX Swiss Exchange on the use of the COSI seal will receive a detailed, practical instruction booklet on the application of this seal of approval in their marketing material. If you as an issuer of COSI certificates would like to affix the COSI seal of approval to your communication documents such as brochures and factsheets, please feel free to contact your sales representative.
