Khun Pat,
I have reviewed the Gen Rep letter addressed to the auditors and approve it to be signed. Please print the attached Gen Rep letter that I have counter signed and then sign as Managing Director and send a copy to all those on this email. This will allow the auditors to complete their work.
Separately can you sign the Thai version tax return as per the instructions from Khun Parisa below.
Khun Parisa, in relation to your question re claiming a tax refund for the 2013 withholding tax, I think the best course of action is for the Company to forgo the refund as there is a high probability that the cost of pursuing the refund will exceed the likely benefit. Therefore do not attempt to claim back the THB 218,867.25
