Dear Ampol Sawasdee-san,
I'm sorry for the delay in contacting you from the last.
We have finished document survey about NSCT's Information Security. 
This survey is on the basis of the submitted document from you.
This result is your current security level against NS group security criteria.
If there are any misunderstandings or mistakes, please let us know.
And If you agree this result, please make a plan to enhance your security level.
(Please input planning sheet)
We hope to receive your plan is Jan/27.
P.S.
Thai Nippon Seiki has been certified NS Security level 4 in March 2015.
(Level 4 is all theme becomes more than "B") If you have a question, please ask TNS or us.
Best regards.
