On June 22, 2011, Bombardier closed both a letter of credit and revolver facility agreement totalling US$1.35 billion with a syndicate of first-quality financial institutions, which were mainly based in North America. The US$600 million letter of credit and the US$750 million unsecured revolving credit facilities which mature in June 2014 are dedicated to supporting Bombardier Aerospace's operations as well as the general needs of Bombardier. They replace two financial agreements: the US$600 million letter of credit facility which was to expire in December 2011 and the US$500 million unsecured revolving credit facility scheduled to mature in August 2011. National Bank Financial Inc., Citigroup Global Markets Inc. and RBC Capital Markets jointly arranged the facilities as mandated lead arrangers and joint bookrunners and BNP Paribas and UBS Securities LLC also acted as joint bookrunners. The mandated lead arrangers and banks were represented on Canadian law matters by Fasken Martineau DuMoulin LLP, with a team that included Marc Novello, Angela Onesi and Francis Trifiro.
