English to Spanish Law/Patents Investment / Securities

The value of a Sub-Fund’s assets may be affected by uncertainties such as political developments, changes in government policies, changes in taxation, restrictions on foreign investment and currency repatriation, currency fluctuations or other economic or political events (for example, if the measures, such as austerity measures and reforms, taken by the governments of the European countries, central banks and other authorities to address the current economic and financial problems in the Eurozone do not work, any such failure may result in adverse consequences.)

¿Cómo puedo traducir "failure" en este contexto?
Mil gracias. :-)))
