AEON Mall (TYO:8905) board approved the cancellation of all treasury stock effective July 1, in line with a previously announced share exchange that will make the company a wholly owned subsidiary of Aeon Co (TYO:8267), according to a Thursday filing on the Tokyo Stock Exchange.

The cancellation is required under the share exchange agreement signed in April, which involves Aeon acquiring all Aeon Mall shares it does not already own.

The cancellation will include shares held as of the record date, including any additional shares acquired through exercise of share purchase demand, the filing said.

As of February 28, Aeon Mall held 4,896 treasury shares.
