What should an International Transfer statement include for Thai visa applications?

Hi all,

Does anyone have an example (or details) on what a "International Transfer" statement should contain from the bank to immigration?

Is it kind of one line of info for each of the last 12 months like;

July 2561, xx,xxxx baht

Aug 2561, xx,xxxx baht

With a total at bottom and obviously signed and stamped on bank paper.

It is for the purpose of extension of stay for over 50 visa using combined income method.

Thanks for any info.
