Banks which have subsidiary and associate companies must also be supervised for capital adequacy on a solo basis (i.e. after deducting all holdings of the share capital of all subsidiaries and associates (that meet the criteria in paragraph CA-1.3.20 above) and excluding all their assets and liabilities from the accounts of the parent bank). Holdings of other participations and equity investments need not be deducted on a solo basis, but should be accounted for at fair value and weighted at 100%. Banks should note paragraph CA-2.2.6 in respect of the treatment described in this paragraph and in paragraph CA-1.3.20.
