[1] During 2012, the increase in goodwill primarily was due to the acquisitions of Chandler/May, CDL, and Procerus at our MST business segment (Note 14). During 2011, goodwill increased $543 million primarily due to the acquisitions of QTC at our IS&GS business segment and Sim-Industries at our MST business segment (Note 14). As a result of the previously discussed reorganization, the goodwill related to the former Electronic Systems business segment was reassigned on a relative fair value basis to the MFC, MST, and Space Systems business segments.

[2] We have no significant long-lived assets located in foreign countries.
