QA
CFS List :	http://www.conflictfreesmelter.org/cfshome.htm
Items maintained in QA folder :	\\hc-storage-20\Local Share\QA\RoHS\GP system survey\Conflict minerals survey (CMRT)-RBA				Including
	1. EICC forms from all vendors on Approved Vendors List ("AVL")
	2. Declaration forms from all vendors on AVL
	3. Source or transaction documents used in reporting conflict minerals usage from vendors on AVL
	4. E-mails, communications and other correspondence from all vendors on AVL made hereunder
	5. Follow-up communications and emails from vendors who are unable to verify sources of minerals covered under the Conflict Minerals policy.
	6. All definitions of Conflict Minerals, and other terms covered under this policy, are defined under the EICC, Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (aka, the “Dodd-Frank Act”), and O2Micro's supporting policies and procedures.
Steps taken by O2Micro:	1. QA shall maintain most current AVL prior to performing its performing its annual audit regarding the use of Conflict Minerals.
	2.  QA shall send EICC compliant forms and declarations, at a minimum, to all vendors on AVL
	3. QA shall confirm the collection of all EICC compliant forms and declarations from each member on AVL prior to the deadlines provided by O2Micro, and follow with said vendors who have not yet complied with policy after deadline.  O2Micro will use all reasonable efforts to get all members of the AVL to comply with its Conflict Minerals reporting requirements.
	4. QA shall prepare the  Conflict Minerals COO Worksheet and present to management for review and approval.
	5.  After final approval, QA shall submit copy of the final Conflict Minerals COO Worksheet for each fiscal year to the finance and legal departments during Q1 of following fiscal year.
Conclusion:	Based on the results of O2Micro's annual Country of Origin (COO) Inquiry, O2Micro reasonably believes that Conflict Minerals have not been used in materials and products used by, or manufactured for, O2Micro.

Remarks:
	List date:
	1. CFS Compliant Tungsten Smelters
	Companies that have been determined to be compliant with the CFSP Supply Chain Transparency Smelter Audit Protocol for Tungsten by completing a CFSP compliance audit conducted by an independent third party audit.
	Please note that CFSI policy requires that no companies may appear on the CFSP Compliant Tungsten Smelters list until a minimum of three companies meet the criteria for listing.
	2. Conflict-Free Smelter Program (CFS)
	Compliant Tin Smelter List
	3. Conflict-Free Smelter Program
	Compliant Tantalum Smelter List
	4. Conflict-Free Smelter Program
	Compliant Gold Refiners List
	Final Rules : A registrant may satisfy the reasonable country  of origin standard by obtaining “reasonably reliable representations” indicating the origin of the conflict materials (i.e., that they are not from  the regions covered under the definition of Conflict Minerals), or that they are recycled or scrap materials.  The current rule notes that such representations can be obtained from the facility directly or from the registrant’s immediate suppliers; however  the registrant must have sufficient reason to believe such to be true (e.g., by considering the sources, the related facts and circumstances, and any relevant “warning signs”).
