This document discusses a structured bond issuance called TIANA by a company called Estructurados Tiana. TIANA bonds work by allocating most of the capital raised to a low-risk deposit that is expected to cover at least 90% of the bond's nominal value at maturity. A small portion of capital is invested in options linked to assets like stocks, commodities, or indexes to provide potential upside for investors. The first TIANA program aims to protect 90-110% of investors' capital. Specific issuances are shown investing fully in bank deposits while allocating the options portion to different exchange-traded funds.
