Sat Aug 31, 2013 7:38pm EDT Verizon has tapped JPMorgan Chase & Co, Morgan Stanley, Barclays, and Bank of America Merrill Lynch to help raise the financing through a mix of bonds and bank loans, the sources said. It plans to pay for another half of the purchase with its own stock. Goldman Sachs declined comment as well. The other banks were not immediately available for comment. Under the terms of the deal, Verizon Communications will buy Vodafone's U.S. holding company, Vodafone Americas, that owns the Verizon Wireless stake and some other assets, the sources said. Verizon will then keep the Verizon Wireless stake and sell European assets back to Vodafone, in a move that is expected to reduce Vodafone's tax bill to around $5 billion, the sources said. The deal marks the third-largest acquisition announcement in corporate history and British telecom giant Vodafone's exit from the large but mature U.S. market.
