 a significant milestone in the evolution of Xura, Mitel Mobile, and 
 Ranzure. These transactions bring together three complementary companies

 accelerating and redefining network transformation for service 
 providers. We are delighted to move forward as one company with a strong 
 and shared commitment to customer enablement and success."
