The result of a combination of two types of products with different characteristics: a deposit, normally short-term, which is usually remunerated higher than market rate, and another product, normally longer term, which can take different forms (a share in an investment fund or other deposit, the remuneration of which may be linked to the quotation price of a share or combination of shares or to the evolution of a stock market index, using different formulas to apply said index). These contracts are not traded on organised secondary markets, and therefore this "deposit" does not allow early repayment, even if the evolution of benchmark indexes were to recommend it. The information brochures of these products are registered at the National Securities Market Commission (CNMV). They are complex, high-risk products for which a credit institution receives money or securities or both from its customers, assuming a refund obligation at an amount which depends on the evolution of a share, a basket or a stock market index. Consequently, there is no commitment to fully refund the capital received.
