SASKATOON, SK, Nov. 14 /CNW/ - Potash Corporation of Saskatchewan Inc. (PotashCorp) today issued the following statement in response to the announcement by BHP Billiton (ASX: BHP; LSE: BLT; NYSE: BHP) (BHP Billiton) that it has withdrawn its unsolicited tender offer to acquire PotashCorp:

    
    BHP Billiton's decision to withdraw its offer underscores the PotashCorp
    Board of Directors' unanimous belief that the BHP Billiton offer
    substantially undervalued PotashCorp and failed to reflect both the value
    of our premier position in a strategically vital industry and our future
    growth prospects.

    We believe our opportunity for growth in the industry is unmatched and we
    are excited about the future. As the food requirements of our growing
    global population continue to increase, we believe PotashCorp has the
    right strategies in place to enhance earnings in the strong market
    conditions we see unfolding. Building further value continues to be our
    primary focus, and with our world-class asset base and proven business
    strategies, we believe we are well-positioned to exceed the expectations
    of our customers and deliver compelling value to our shareholders.
