※On November 16, 1999, the date of the merger, the Company (formerly JPC Holding Co., Ltd., the formal surviving company; Head office: 3-3-23 Misakicho, Chiyoda-ku, Tokyo; Fiscal year ending: March) absorbed the former Japan Pure Chemical Co., Ltd. (the actual surviving company; Head office: 2-26-7 Minamiikebukuro, Toshima-ku, Tokyo; Fiscal year ending: May). At this time, the Company changed its name to Japan Pure Chemical Co., Ltd., and relocated its head office to the address of the head office of the former Japan Pure Chemical Co., Ltd., the actual surviving company (2-26-7 Minamiikebukuro, Toshima-ku, Tokyo), as the Company had succeeded all assets, liabilities, rights and obligations of the former Japan Pure Chemical Co., Ltd. The objective of this merger was to transfer ownership (MBO) of the former Japan Pure Chemical Co., Ltd. The Company, which had been inactive prior to the merger, took over all operations of the absorbed company at the time of the merger.
Consequently, the actual surviving company is the former Japan Pure Chemical Co., Ltd., the absorbed company. For this reason, unless otherwise stated, all information provided above for the period prior to the merger describes the former Japan Pure Chemical Co., Ltd., the actual surviving company.
