一. Background

The mining of rare metals such as cassiterite, wolframite, coltan and gold in the Democratic Republic of Congo (DRC) and its
neighboring countries and regions has caused serious human rights and environmental problems, known as "Conflict
Minerals" (CM), which are now widely used in electronics.On July 21, 2010, United States President Barack Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection
Law Dodd-Frank Wall Street reform and consumer protection law, which requires the use of gold, United States companies of
tantalum, tin, tungsten, cobalt, mica and other metals and derivatives report to the SEC whether their metal raw materials come
from illegal mining areas such as Congo and neighboring countries.

二. Our Policy Statement

1. Do not support or use metals derived from armed conflicts and illegal mining, that is, the so-called "conflict minerals";

2. The company's suppliers should investigate the metals contained in their products, such as gold, tantalum, tin, tungsten, cobalt,
mica, etc., and confirm the source of these metals;
