"We engaged BSR, an independent,non-profit,global organization devoted to building a just and sustainable world, to help us evaluate risks of slavery and human trafficking in our business operations and related supply chains. From BSR’s assessment, we determined that our electronics manufacturing supply chain was at higher risk for potential human rights abuses than our business operations and supply chains of our remaining business segments, which were determined to be low-risk for these abuses.We are therefore prioritizing our electronics manufacturing operations in our group-wide efforts."

I think Sony has identified its higher risks in electronics manufacturing supply chain.
