Dear Dip
As per section 203. (1) Every company belonging to such class or classes of companies as may be prescribed shall have the following whole-time key managerial personnel,—
(i) managing director, or Chief Executive Officer or manager and in their absence,
a whole-time director;
(ii) company secretary; and
(iii) Chief Financial Officer :
So in your case as there is CEO already you need not to appoint Md/WTD/Manager.
(In terms of rule 3 of Chapter XIII )A company shall file a return of appointment of a Managing Director, Whole Time Director or Manager, Chief Executive Officer (CEO), Company Secretary and Chief Financial Officer (CFO) within sixty days of the appointment, with the Registrar in Form No. MR.1 along with such fee as may be specified for this purpose.
