Zhi Tong Zhi Zi (2022) No. 110a008092 Sunresin New Materials Co.Ltd Xi'An(300487) all shareholders:
We have accepted the entrustment to verify the confirmation of the board of directors of Sunresin New Materials Co.Ltd Xi'An(300487) (hereinafter referred to as Sunresin New Materials Co.Ltd Xi'An(300487) company) on the effectiveness of internal control related to financial statements on December 31, 2021 The responsibility of the board of directors of Sunresin New Materials Co.Ltd Xi'An(300487) company is to establish and improve internal control and maintain its effectiveness in accordance with the basic norms of enterprise internal control, and ensure that the attached self-evaluation report on internal control of Sunresin New Materials Co.Ltd Xi'An(300487) company truly and completely reflects the internal control related to financial statements of Sunresin New Materials Co.Ltd Xi'An(300487) company on December 31, 2021. Our responsibility is to express opinions on the effectiveness of internal control related to the financial statements of Sunresin New Materials Co.Ltd Xi'An(300487) company on December 31, 2021. We have carried out the assurance work in accordance with the provisions of other assurance business standards for Chinese certified public accountants No. 3101 - assurance business other than audit or review of historical financial information. In the process of assurance, we have implemented other procedures including understanding, testing and evaluating the rationality of internal control design and effectiveness of implementation related to financial statements, as well as other procedures we deem necessary. We believe that our assurance provides a reasonable basis for expressing opinions.
Internal control has inherent limitations, and there is the possibility that misstatement may occur and not be found due to error or fraud. In addition, as changes in circumstances may lead to inappropriate internal control, or reduce the degree of compliance with control policies and procedures, it is risky to speculate the effectiveness of internal control in the future according to the internal control assurance results.
In our opinion, Sunresin New Materials Co.Ltd Xi'An(300487) company has effectively maintained the internal control related to financial statements established in accordance with the basic norms of enterprise internal control in all major aspects on December 31, 2021.
