Consolidated financial statement for f.y 2015-16

Dear all,

I have two private limited say A Pvt Ltd & B Pvt Ltd.

Company A has Two shareholder X & Y holding 100% of sharecapital of the company.

Company B has also those two shareholder X & Y holding together 51% of sharecapital of the company.

Both the company has three directors in common say A B & C but holding shares only in B Pvt Ltd.

My question is that whether there is a relation between two company to be taken as Holding Subsidiary or both are associates company with reference to difinition given in the AS 21 & 23 and requirement of Companies Act, 2013 for consolidation of Financial Statement.

Also is there any exemption from preparation of consolidated financial statement to private limited company for F.Y 2015-16?

Please provide appropriate guidance....
