Warner Chilcott's EGM had approved the proposed takeover of the company by Waren Acquisition Ltd.
The Waren Acquisition consortium has offered a bid of £1.62 billion sterling for the Northern Ireland-based pharmaceutical company.
The Warner Chilcott board has backed the 862 pence per share takeover. The price includes a 3 pence per share interim dividend for the year to the end of September, which will not be paid separately if the deal goes through.
The takeover still remains subject to court approval - this is expected to be granted on December 20.
Warner Chilcott, which specialises in women's health and skin products, is listed in Dublin, London and New York.
The company has asked for its shares to be delisted from the Dublin, London and New York Stock Exchanges on January 6, 2005.
