Friends, the traditional meaning of the term promoter (i.e. a person who is involved in formation of a company) is not more applicable under CA 2013. The definition given in Sec.2(69) is very wide and now company can identify any person as its promoter in the annual return. In your case also NBFC can also be identified as a promoter.
However, one precaution needs to be taken here. The effect of declaring a person as a promoter is that he will be liable for action for non-compliances by the company in certain specified sections where promoter has also been made liable in addition to directors and other officers in default [e.g. Sec.7(6), 35(1)(c), 42(10) etc.]. Hence to avoid any dispute in future, it will be advisable to take his consent for his name being declared as a promoter, though there is no provision for the same in the Act.
