Openwave Systems (OPWV -1%) adopts a poison pill with a 4.99% trigger in an effort to protect its $1.6B in tax assets stemming from its net operating losses and tax credit carry forwards. A triggering event would occur if any entity acquires 4.99% or more of the software maker’s stock, diluting the entity’s ownership interest.
