'Acquisition' means the acquiring by a bank of beneficial or legal ownership of capital instruments issued by another entity. This would not include securities underwriting until the expiry of the underwriting period (where separate arrangements apply elsewhere in this Module). Acquisition may also be in the form of exercising of rights to take control of capital instruments pledged as collateral. The pledging of capital instruments by a customer to a bank as collateral (e.g. for the purpose of obtaining credit) does not in itself mean that an "acquisition" has taken place. Acquisition also does not include the establishment of new subsidiaries by the bank. Regulatory requirements for the establishment of SPVs and subsidiaries are contained in Section BR-5.2.
