Dear Organizers:

First of all thanks a lot to everybody for all the efforts of organizing this event. Today I happily paid my registration fee (payment confirmation attached).

Unfortunately my university requires for reimbursement of this cost an official invoice, which must be directed to

Fundación Universidad de las Américas Puebla

RFC FUA851220CF0

The last number is the tax number which according to local rules is indispensable and must appear on that invoice. I also indicated that in the observations, but I thought it is better to write about this need also directly to you.

Thank you very much for your help.

Best regards,

Martin
