The “responsibilities of certified public accountants for the audit of financial statements” in the audit report further expounds our responsibilities under these standards. In accordance with the code of professional ethics for Chinese certified public accountants, we are independent of Sinomag Technology Co.Ltd(300835) company and have fulfilled other responsibilities in terms of professional ethics. We believe that the audit evidence we have obtained is sufficient and appropriate, which provides a basis for our audit opinion.
3、 Key audit matters
The key audit matters are the most important matters that we consider to audit the current financial statements according to our professional judgment. The response to these matters is based on the overall audit of the financial statements and the formation of audit opinions. We will not express separate opinions on these matters.
（1） Impairment of accounts receivable
1. Event description
See notes III (x) and V (I) 4 to the financial statements for relevant information disclosure.
As of December 31, 2021, the book balance of accounts receivable of Sinomag Technology Co.Ltd(300835) company was 20810284442 yuan, the bad debt provision was 654991880 yuan, and the book value was 20155292562 yuan.
Sinomag Technology Co.Ltd(300835) the management of the company (hereinafter referred to as the management) measures its loss reserves according to the expected credit loss amount in the whole duration based on the credit risk characteristics of various accounts receivable and the combination of individual accounts receivable or accounts receivable. For accounts receivable whose expected credit loss is measured on a single basis, the management comprehensively considers the reasonable and reliable information about past events, current situation and future economic situation forecast, estimates the expected cash flow received, and determines the bad debt provision to be withdrawn accordingly; For the accounts receivable whose expected credit loss is measured on the basis of portfolio, the management divides the portfolio based on the aging, refers to the historical credit loss experience, and adjusts it according to the forward-looking estimation, and prepares the comparison table between the aging of accounts receivable and the expected credit loss rate, so as to determine the accrued bad debt reserves.
As the amount of accounts receivable is significant and the impairment test of accounts receivable involves significant management judgment, we determine the impairment of accounts receivable as a key audit event.
2. Audit response
For the impairment of accounts receivable, our audit procedures mainly include:
(1) Whether the internal control of impairment has been evaluated and whether the internal control of impairment has been implemented;
(2) Review the subsequent actual write off or reversal of accounts receivable for which bad debt reserves have been accrued in previous years, and evaluate the accuracy of previous forecasts of the management;
(3) Review the relevant considerations and objective evidence of the management’s credit risk assessment of accounts receivable, and evaluate whether the management has properly identified the credit risk characteristics of various accounts receivable;
(4) The management shall check the accuracy of the forecast of the individual cash flow and the forecast of the expected cash flow, and check the accuracy of the forecast of the individual cash flow with that of the management;
(5) For accounts receivable whose expected credit loss is measured on the basis of portfolio, evaluate the rationality of the management’s division of portfolio according to the characteristics of credit risk; Evaluate the rationality of the comparison table between the aging of accounts receivable and the expected credit loss rate determined by the management based on historical credit loss experience and forward-looking estimation; Test the accuracy and completeness of the data used by the management (including accounts receivable aging, historical loss rate, migration rate, etc.) and whether the calculation of bad debt reserves is accurate;
(6) Check the post period collection of accounts receivable and evaluate the rationality of the management’s provision for bad debts of accounts receivable;
(7) Sample accounts receivable, implement letter verification procedures, and verify the existence and accuracy of accounts receivable;
(8) Check whether the information related to the impairment of accounts receivable has been properly presented in the financial statements.
（2） Net realizable value of inventories
1. Event description
See notes III (XI) and V (I) 8 to the financial statements for relevant information disclosure.
As of December 31, 2021, the book balance of inventories of Sinomag Technology Co.Ltd(300835) company was RMB 23787828304, the provision for depreciation was RMB 22715171, and the book value was RMB 23765113133.
On the balance sheet date, inventories are measured at the lower of cost and net realizable value, and inventory falling price reserves are withdrawn according to the difference between inventory category cost and net realizable value. On the basis of considering the purpose of holding the inventory, the management determines the estimated selling price according to the actual selling price, the market selling price of the same or similar products and the future market trend, and determines the net realizable value of the inventory according to the estimated selling price minus the estimated cost to be incurred at the time of completion, the estimated selling expenses and relevant taxes.
Since the amount of inventory is significant and the determination of net realizable value of inventory involves significant management judgment, we determine the net realizable value of inventory as a key audit event.
2. Audit response
For the net realizable value of inventories, our audit procedures mainly include:
(1) Understand the key internal controls related to the net realizable value of inventory, evaluate the design of these controls, determine whether they are implemented, and test the operation effectiveness of relevant internal controls;
(2) Review the management’s forecast of net realizable value of inventories and actual operating results in previous years, and evaluate the accuracy of the management’s previous forecasts;
(3) Review the management’s forecast of the estimated selling price of inventory by sampling, and compare the estimated selling price with historical data, future situation, market information, etc;
(4) Evaluate the rationality of the management’s estimation of the costs, selling expenses and relevant taxes to be incurred from the completion of the inventory;
(5) Test whether the management’s calculation of the net realizable value of inventory is accurate;
(6) Combined with inventory supervision, check whether there are long stock age, obsolete models, fluctuations in production costs or selling prices, changes in technology or market demand in the ending inventory, and evaluate whether the management has reasonably estimated the net realizable value;
(7) Check whether the information related to the net realizable value of inventories has been properly presented in the financial statements. 4、 Other information
The management is responsible for other information. Other information includes the information covered in the annual report, but does not include the financial statements and our audit report.
Our audit opinion on the financial statements does not cover other information, and we will not issue any form of assurance conclusion on other information.
In combination with our audit of the financial statements, our responsibility is to read other information and consider whether other information is materially inconsistent with the financial statements or the information we have learned in the audit process, or there seems to be material misstatement.
Based on the work we have performed, if we determine that there is a material misstatement in other information, we should report that fact. In this regard, we have nothing to report.
5、 Responsibilities of management and governance for financial statements
The management is responsible for preparing the financial statements in accordance with the provisions of the accounting standards for business enterprises to achieve a fair reflection, and designing, implementing and maintaining necessary internal control so that the financial statements are free from material misstatement caused by fraud or error.
When preparing the financial statements, the management is responsible for evaluating the sustainable operation ability of Sinomag Technology Co.Ltd(300835) company, disclosing matters related to sustainable operation (if applicable), and applying the assumption of sustainable operation, unless liquidation is planned, operation is terminated or there is no other realistic choice.
Sinomag Technology Co.Ltd(300835) corporate governance (hereinafter referred to as governance) is responsible for supervising the financial reporting process of Sinomag Technology Co.Ltd(300835) company.
6、 Responsibilities of certified public accountants for the audit of financial statements
Our goal is to obtain reasonable assurance on whether the financial statements as a whole are free from material misstatement due to fraud or error, and issue an audit report containing audit opinions. Reasonable assurance is a high-level assurance, but it does not guarantee that the audit performed in accordance with the audit standards will always be found when a major misstatement exists. Misstatement may be caused by fraud or error. If it is reasonably expected that the misstatement alone or in summary may affect the economic decisions made by the users of the financial statements based on the financial statements, the misstatement is generally considered to be significant.
In the process of carrying out the audit work in accordance with the audit standards, we use professional judgment and maintain professional doubt. At the same time, we also carry out the following work:
（1） Identify and assess the risks of material misstatement of financial statements due to fraud or error, design and implement audit procedures to deal with these risks, and obtain sufficient and appropriate audit evidence as the basis for issuing audit opinions. Since fraud may involve collusion, forgery, intentional omission, misrepresentation or override of internal control, the risk of failing to find major misstatement caused by fraud is higher than that caused by error.
（2） Understand the internal control related to audit in order to design appropriate audit procedures, but the purpose is not to express an opinion on the effectiveness of internal control.
（3） Evaluate the appropriateness of accounting policies selected by the management and the rationality of accounting estimates and related disclosures.
（4） Draw conclusions on the appropriateness of management’s use of going concern assumptions. At the same time, according to the audit evidence obtained, draw a conclusion on whether there are major uncertainties in the matters or circumstances that may lead to major doubts about the sustainable operation ability of Sinomag Technology Co.Ltd(300835) company. If we conclude that there is significant uncertainty, the auditing standards require us to draw the attention of statement users to the relevant disclosures in the financial statements in the audit report; If the disclosure is insufficient, we should express a non unqualified opinion. Our conclusions are based on the information available as of the date of the audit report. However, future events or circumstances may cause Sinomag Technology Co.Ltd(300835) company to be unable to continue its business.
（5） Evaluate the overall presentation, structure and content of the financial statements, and evaluate whether the financial statements fairly reflect relevant transactions and events.
（6） Obtain sufficient and appropriate audit evidence on the financial information of entities or business activities in Sinomag Technology Co.Ltd(300835) company to express audit opinions on the financial statements. We are responsible for guiding, supervising and implementing the group audit, and take full responsibility for the audit opinions.
We communicated with the management on the planned audit scope, schedule and major audit findings, including the internal control defects that we identified in the audit.
We also provide a statement to the management that we have complied with the professional ethics requirements related to independence, and communicate with the management all relationships and other matters that may reasonably be considered to affect our independence, as well as relevant preventive measures (if applicable).
From the matters communicated with the management, we determine which matters are the most important for the audit of the current financial statements, thus constituting key audit matters. We describe these matters in the audit report, unless laws and regulations prohibit the public disclosure of these matters, or in rare cases, if the negative consequences of communicating a matter in the audit report are reasonably expected to exceed the benefits in the public interest, we determine that we should not communicate the matter in the audit report.
