Reuters reported, citing sources familiar with the matter, that Royal Dutch Shell is seeking to secure a $7 billion credit facility in North America as back-up for its $70 billion acquisition of BG Group.

Reuters said JPMorgan Chase is arranging the facility, which will involve up to 20 banks and institutional investors, according to sources close to the matter.

Reuters noted the facility will be used as a “back-up” for funds already raised to finance the deal, according to one source.
