Formation of audit committee

Dear Experts,

My Company is a Nidhi Company. We accept public Deposits more that 50 crores. But As per CA2013 "Deposits" defination the money which we receive from public is not considered as Deposits as it is exempted by RBI. 

So my question is should we form audit committee u/s 177 of Companies Act 2013. 

Our paid up capital is well below 10 crore. 

Please give your valuble comments.
