In fiscal year 2014, two former employees of Exar’s French subsidiary asserted claims in the French Labor Courts against that subsidiary for alleged unfair dismissal. We believe that the former employees were terminated in accordance with the requirements of French law and that the former employees’ claims are not supported by evidence. On December 22, 2014, Exar and one former employee entered into a settlement agreement resolving all claims made in the litigation. The French Labor Court in the other matter rendered a judgment in favor of the other employee on January 21, 2015 that we intend to appeal. We continue to dispute the claims and intend to continue to vigorously protect our interests.
