ViaSat Litigation Update

RICHMOND, BC, Aug. 11, 2014 /CNW/ - MacDonald, Dettwiler and Associates Ltd. 
("MDA" or the "Company") (TSX:MDA), a global communications and information 
company, today announced that in an order issued August 8, 2014, the federal 
court hearing ViaSat Communications, Inc.'s (ViaSat) lawsuit against Space 
Systems/Loral, LLC (SSL) vacated all damages the jury awarded to ViaSat, 
finding that the jury award was a "miscarriage of justice." The Court ordered 
a new trial on damages. 
The Court deferred any ruling on ViaSat's motion for a permanent injunction, 
which seeks to bar SSL from manufacturing satellites which are significantly 
similar to Jupiter-1 with respect to the three patented technologies at issue 
in the case, scheduling argument on that motion for August 26, 2014.
