4. Deconsolidation of SGT

In November 2013, the board of directors of SGT approved a voluntary plan for liquidation. On December 30, 2013, the board of directors of SGT appointed a liquidator. Under Italian regulations, the liquidation process was administered by the liquidator and the Company did not have the ability to exercise influence over SGT. As a result of these actions, the Company deconsolidated SGT on December 30, 2013 when the Company ceased to have a controlling financial interest in SGT. The fair value of the Company’s retained investment in SGT was zero as of December 31, 2014 and December 31, 2013.
