¿Cómo traduciriáis "debt reduction bills" en el siguiente contexto?

An EFA would take over the eurozone rescue funds – the €440bn European Financial Stability Facility and the €500bn European Stability Mechanism – and establish a “debt reduction fund”. The latter, very similar to a “debt redemption fund” proposed by the council of economic advisers to the German government, would acquire all eurozone government debt in excess of 60 per cent of their gross domestic product – the debt ceiling they are supposed to aim at. The fund would then issue “debt reduction bills” as a joint obligation of the eurozone countries. Mr Soros suggests they should be treated as the highest quality collateral by the ECB, and would be attractive to investors.
