The findings from the data analysis show that there was no CSR significant impact on company's idiosyncratic and systematic risk. However, it has a weak negative impact on total risk. The CSR dimensions that affect company risk are supply chain partnerships and tax contributions. The supply chain partnerships are negatively associated with company's systematic and idiosyncratic risk. This finding was also consistent after adding the control variables. On the contrary, tax contributions are positively associated with higher systematic and idiosyncratic risk to the company.
