Assumed Factors QIAGEN Can Only Partially Influence:
Assumptions that we may influence include the assumption that the business structure remains unchanged from the date of this forecast to the end of the third quarter and the end of 2009, in particular that no further acquisitions will be made and no further divestments will occur. For the avoidance of doubt, the acquisition of DxS Ltd. is included into the forecast. In recent years, we have made a number of strategic acquisitions and disposals expanding and focusing our technology and product offering and we plan to continue to do so. If we were to engage in any such transactions, the forecast provided here would necessarily be inapplicable and accordingly, should not be relied upon in such circumstances.
