I noted the following comments from the RNS quoted:
On completion of the Merger, Woodside will issue new shares expected to comprise approximately 48% of all Woodside shares (on a post-issue basis) as consideration for the acquisition of BHP Petroleum. The Merger ratio is based on the number of Woodside shares at the effective date. The number of new shares issued on completion will be adjusted to reflect shares issued by Woodside under its dividend reinvestment plan after the effective date.
The new Woodside shares will be distributed to BHP shareholders as an in-specie fully franked dividend.
and
Woodside listings and governance
Woodside will retain its primary listing on the Australian Securities Exchange (ASX).
Woodside is currently pursuing a secondary listing on the New York Stock Exchange (NYSE) through an American depository receipt (ADR) arrangement, with a target of being active by completion. The NYSE listing would provide increased access to international equity and debt markets. Additional secondary listings are being evaluated.
One hopes that they will pursue a London listing, otherwise we BHP holders may find holding a share not quoted in London to be a bit of a problem. South32 did get a London listing, so no problem holding that.
