1.According to me, send copy of financial statements to CFO by email and he will take out its printing and after signing send the same by courier from abroad and other directors can sign later.
2.Otherwise all directors and CS will sign in the same meeting and send the scanned copies of same to CFO abroad. CFO will sign those copies and send by email/courier back to company. I am not one hundred percent sure that this will be legal or not.
To make situation more evident, Plz. provide dates of signing of financial statement and auditor also. Date of AGM also reqd.
