DOC's ongoing AD and CVD investigations are based on petitions filed last December by SolarWorld Industries America, Inc. ("SolarWorld"), the U.S. subsidiary of Germany-based SolarWorld AG. DOC's preliminary CVD determination is the latest determination in a series of cases involving solar products from China. DOC issued AD and CVD orders on certain solar cells exported from China in 2012, and the EU recently entered into a settlement agreement with Chinese exporters of solar products.
