The total consideration payable under the Final Offers will amount to approximately £2.0 billion. In addition to cash from NASDAQs own reserves, NASDAQ and NAL will finance the acquisition of LSE by borrowing under new credit facilities and issuing preferred stock. NASDAQ expects this debt to be comfortably paid down from the strong cash flow generated by the combined entity. Further information on NALs financing arrangements will be contained in the Offer Document.
Greenhill, financial adviser to NASDAQ and NAL, is satisfied that resources are available to NAL sufficient to satisfy in full the cash consideration payable to LSE Shareholders under the terms of the Transaction.
