Beneficial Ownership/Substantial ownershipbeneficial

[Prakash Joshi]

Can anyone   advise on  the  applicability of section 89 and 90  and compliance requirements in the following cases.

 1) 25% holding of an HUF in a Pvt. Ltd. co  and public unlisted company

(2) 48% holding of a Unlisted Public Co in a Pvt Ltd co 

(3) 0.20% Shareholding of an individual in a Unlisted Public co as nominee of a HUF or a nominee of a Pvt Ltd/Ltd co 

 4) 16.5% holding of a Pvt Co in another Pvt co .

What is the way out if all want to comply but only from the current date. Is it possible?

Those  who have dealt with such cases may please share their views.

Thanks
