Change in residential status from nri to ri

Residential status of one of my Non-Resident Indian (NRI) Client has changed to Resident Indian as he has decided to return permanently to India. On the day of returning to India he was having various foreign assets like Investments in Shares and securities of overseas entities, Balance in Foreign Bank accounts, Loan to Overseas Corporate entities & Individual. Query: Is he liable to inform to RBI or any other authorities about his foreign assets (acquired by him when he was NRI).
