Second-tier brokerage Kankaku Securities Co. and Kokyo Securities Co., a small brokerage affiliated with Nippon Telegraph and Telephone Corp., said Monday they will merge Oct. 1, with Kankaku as the surviving entity.

The merged company will be renamed Mizuho Investors Securities Co., in line with the planned formation Sept. 29 of Japan’s largest banking group, the Mizuho Financial Group, by Dai-Ichi Kangyo Bank, Fuji Bank and the Industrial Bank of Japan, the brokerages said. Kankaku and Kokyo are affiliates of DKB.

Each Kokyo share, with a par value of 500 yen, will be exchanged for nine Kankaku shares, the par value of which is 50 yen, they said.

Kankaku Vice President Shozo Hibi, who is to become president June 29, will take the helm of the new firm, they said.

The Tokyo-based Kankaku, with 55 domestic outlets and 1,214 employees as of March 31, posted a pretax profit of 17.88 billion yen and a net loss of 64.37 billion yen on operating revenues of 58.77 billion yen in fiscal 1999.
