Thales-Raytheon Systems Co. Ltd (TRS) Joint Venture Thales-Raytheon Systems Co. Ltd. (TRS) Joint Venture
In 2001, we formed the TRS joint venture with Thales S.A. through our Integrated Defense Systems (IDS) segment. The TRS joint venture involved three operating companies, one of which, Raytheon Command and Control Solutions LLC (RCCS LLC), we controlled and consolidated, and the other two, Thales-Raytheon Systems Company S.A.S. (TRS SAS) and Thales-Raytheon Systems Air and Missile Defense Command and Control S.A.S. (TRS AMDC2), we accounted for using the equity method through our investment in TRS.

In 2016, Thales S.A. and Raytheon amended and restated the TRS joint venture agreement to reduce the arrangement to TRS AMDC2 only and limit its scope to NATO-only business opportunities involving air command and control systems, theatre missile defense and ballistic missile defense. As a result, we acquired Thales S.A.’s noncontrolling interest in RCCS LLC and sold our equity method investment in TRS SAS for a net cash payment to Thales S.A. of $90 million, which was classified as a financing activity in our consolidated statements of cash flows. We recorded our acquisition of RCCS LLC at fair value, which resulted in a reduction to equity of $167 million before tax, $197 million after tax, and the sale of TRS SAS at fair value, which resulted in a tax-free gain of $158 million that was recorded in operating income through a reduction in cost of sales at our IDS segment. TRS AMDC2 continues to be a joint venture between Thales S.A. and Raytheon that is accounted for using the equity method.
