1. Audit status of the BNBM Results Forecast
   This results forecast has not been pre-audited by a certified public accountant.
2. Explanations on changes in results of BNBM
   The expected turnaround in the results of BNBM is mainly because Taishan Gypsum Co., Ltd.,* ( 泰 山 石 膏 有 限 公 司), a subsidiary of BNBM, reached a settlement with the majority of the plaintiffs in the multi-jurisdictional class actions in the gypsum board litigation in the United States and incurred relevant settlement fees of RMB1,846.4737 million, which was classified as non- recurring gains and losses. No large settlement amount is expected for January to September this year, so it is expected that there will be a year-on-year increase in the net profit attributable to the parent company of BNBM.
