The controlling shareholder changed within the same ultimate group
The report says the ultimate controller, China National Building Material Group, did not change during 2005. A transfer of 161,493,120 shares, or 37.79% of the listed company, moved the controlling stake from BNBM Group to China National Building Materials and Equipment Import and Export Corporation, reorganized as CNBM Limited on 28 March 2005. CNBM Limited held 171,669,120 shares, or 40.17%, at year end; Zhenshi Group held 22.26%. The narrative dates the transfer to 4 January, while the corporate-history note records its regulatory approval on 28 December 2004 and transfer-registration confirmation on 4 February 2005. These are separately reported milestones. The report contains two control diagrams: at the 2005 close CNBM Group held 100% of BNBM Group, which held 59.11% of CNBM Limited, alongside CNBM Group's direct 26.54% stake. The later diagram, following CNBM Limited's Hong Kong listing on 23 March 2006, shows 37.64% and 16.9% respectively. CNBM Limited's 40.17% holding in the listed company appears in both. The later ownership percentages are not substituted into the year-end structure.
