  (b) UMC has adopted an “EICC-GeSI Conflict Minerals Reporting Template” created by the Electronic Industry Citizenship Coalition (EICC) and the Global e-Sustainability Initiative (GeSI), which is consistent with EICC’s and GeSI’s Conflict Free Smelter (CFS) Program and other similar activities, when conducting a country origin inquiry regarding those Conflict Materials utilized by UMC and UMC’s contractors. After the reasonable country origin inquiry, UMC determines that Conflict Minerals utilized by UMC and UMC’s contractors did not originate in the Democratic Republic of the Congo (“DRC”) or an adjoining country (together with DRC, the “Covered Countries”).
