(2) Basis of internal control evaluation and identification standard of internal control defects

The company organizes and carries out internal control evaluation according to the enterprise's internal control standard system and external supervision requirements.

The board of directors of the company adjusted the identification standard of internal control defects in previous years according to the identification requirements of the enterprise internal control standard system for major defects, important defects and general defects, combined with the changes of the company's scale, industry characteristics, risk preference, risk tolerance and other factors, and distinguished the internal control of financial report from the internal control of non-financial report. The identification standard of internal control defects after adjustment is as follows:

The identification standards of internal control defects determined by the company are as follows:

1. Identification criteria for defects in internal control over financial reporting

The quantitative criteria for the evaluation of internal control defects in financial reporting determined by the company are as follows:

Major defects of the project major defects general defects

Potential misstatement of total profit ≥ 5% of total profit ≤ 3% of total profit < misstatement of total profit < 3% of total profit

At 5% of false positives

Potential misstatement of total assets ≥ 3% of total assets ≤ 0.5% of total assets ≤ misstatement < 0.5% of total assets < 3% of total assets

Total misstatement of operating income ≥ 0.5% of total operating income ≤ misstatement economic misstatement amount of total operating income potential misstatement 1% of total operating income 0.5%

Owner's equity misstatement ≥ 0.5% of total owner's equity ≤ misstatement misstatement 1% of total owner's equity potential misstatement 0.5% of total owner's equity

The above standards directly depend on the importance of financial reporting misstatement that may be caused by the existence of internal control defects. This degree of importance mainly depends on two factors: whether the defect will lead to the failure of internal control to prevent or detect and correct the misstatement of financial reports in time; The amount of potential misstatement that may be caused by the defect alone or in combination with other defects.

The qualitative criteria for the evaluation of internal control defects in financial reporting determined by the company are as follows:
