Cross-holdings restriction bars significant shareholding or board representation across collective investment managers, with a one-year cure period. Regulation 9B prohibits promoters, their associates or group companies from holding ten percent or more of shareholding or voting rights in, or having representation on the board of, any other Collective Investment Management Company or its trustee, and similarly bars shareholders holding ten percent or more in a Collective Investment Management Company or trustee from comparable holdings or board representation in another such company; incidental acquisitions from reorganizations must be remedied within one year.
