Spanish to English Law/Patents Law (general) Carta de referencia

Hi,

I have difficulties to translate the following sentence into English:

"La emisión de éste certificado, sin embargo, no confiere ninguna responsabilidad, económica o de cualquier otra clase en ésta posible cooperación."

I am not quite sure if I understood the meaning behind. Please have a look at the following translation:

With the publication of this testimonial we do not, however, assume financial liability or liability in any other matter with respect to this cooperation.

Do you have any other ideas?

Thanks in advance
