(4) RFS Holdings B.V. (RFS) owns 100% of the outstanding shares of RBS Holdings N.V. (ABN AMRO Holding N.V. prior to 1 April 2010). Until 31 December 2010, the company owned 38% of RFS; the balance of shares were held by the State of the Netherlands, successor to Fortis N.V., Fortis SA/NV, and Banco Santander S.A. (the consortium members). Although the company did not control a majority of the voting rights in RFS, through the terms of the Consortium and Shareholders' Agreement and RFS's Articles of Association, it controlled the board of RFS and RFS is a subsidiary of the company. RFS Holdings has substantially completed the separation of the business units of ABN AMRO Holding N.V. As part of this reorganisation, on 6 February 2010, the businesses of ABN AMRO Holding N.V. acquired by the Dutch State were legally demerged from the ABN AMRO Holding N.V. businesses acquired by the Group and were transferred into a newly established holding company, ABN AMRO Bank N.V. (save for certain assets and liabilities acquired by the Dutch State that were not part of the legal separation and which will be transferred to the Dutch State as soon as possible). Legal separation of ABN AMRO Bank N.V. occurred on 1 April 2010, with the shares in that entity being transferred by RBS Holdings N.V. to a holding company called ABN AMRO Group N.V., which is owned by the Dutch State. Following legal separation, RBS Holdings N.V. has one direct subsidiary, The Royal Bank of Scotland N.V. (RBS N.V.), a fully operational bank within the Group. RBS N.V. is independently rated and regulated by the Dutch Central Bank. On 31 December 2010, the shareholdings of RFS were amended such that approximately 98% of its issued share capital is now held by the company with the remainder owned by the State of the Netherlands and Banco Santander S.A. Certain assets within RBS N.V. continue to be shared by the Consortium Members. On the division of an entity by demerger, Dutch law establishes a cross liability between surviving entities in respect of the creditors at the time of the demerger. RBS N.V.’s cross liability is limited by law to the lower of its equity and the debts of ABN AMRO Bank N.V. on 1 April 2010. The likelihood of any cross liability crystallising is considered remote.
