1、 Issuer description

(I) according to the contract of F103 product technology licensing fee of 20 million yuan, whether Wuhan Xinxin has delivered relevant technical materials to the issuer, the company will confirm the rationality of the licensing fee payable at the time of subsequent mass production, and whether the relevant accounting treatment meets the provisions of the accounting standards for business enterprises

1. Specific agreement on MCU product technology license contract

The issuer and Wuhan Xinxin signed the supplementary agreement II of MCU product R & D, license and sales agreement (hereinafter referred to as “MCU supplementary agreement II”) in May 2021, which made a supplementary agreement on the license fund for Wuhan Xinxin to license MCU product technology. According to the introduction of relevant personnel of the issuer who participated in the signing of the contract, interviews and letters with relevant personnel of Wuhan Xinxin, the authorized content includes the product technology corresponding to the two products L003 and F103. Among them, L003 product technology basically meets the mass production conditions when delivered, and individual bugs need to be revised and repaired to meet the application conditions; F103 product technology only completes the design and preliminary streaming work at the time of delivery, and the design and chip verification process is incomplete. It still needs subsequent R & D resources to realize engineering samples and mass production, and the results may be uncertain.

Therefore, with regard to L003 product technology licensing fee, The MCU supplementary agreement II stipulates as follows: “a) the first authorization fee is 10000000 yuan only (in words: RMB ten million yuan only); Party B shall pay it within (10) days after the signing of this supplementary agreement II; b) Party B shall pay the second authorization fee of 10000000 yuan only (in words: RMB ten million yuan only) before the end of December 2021.”

About F103 product technology license fund, The MCU supplementary agreement II stipulates as follows: “C) before the end of December 2022, Party B plans to pay the remaining authorization fee of 20000000 yuan only (in words: RMB 20 million yuan only). The payment time of F103 remaining authorization fee is determined by the research and development progress of F103 project samples and mass production agreed by both parties (see Annex L003 & F103 data review for details) , if the engineering samples and mass production progress of F103 fail to meet the verification standards before December 31, 2022, Party A and Party B shall separately agree on the payment time, amount and further R & D plan. “

To sum up, the F103 product technology authorization fund shall not exceed 20 million yuan. The specific payment time and amount shall be determined according to the F103 project samples and the R & D Progress of mass production.

2. Wuhan Xinxin has delivered relevant technical materials to the issuer

In May 2021, Wuhan Xinxin has delivered all technical materials related to F103 product technology agreed in MCU supplementary agreement II to the issuer.

3. The company will confirm the rationality of the authorization fee payable at the time of subsequent mass production of products, and whether the relevant accounting treatment complies with the provisions of the accounting standards for business enterprises

(1) Reasons for the issuer’s failure to carry out accounting treatment when obtaining the relevant technical data of F103 product

Since F103 product technology only completes the design and preliminary streaming work at the time of delivery, and the design and chip verification process is incomplete, it still needs to invest subsequent R & D resources to realize engineering samples and mass production, and the results may be uncertain. If the progress of engineering samples and mass production of F103 does not meet the above reasons before December 31, 2022, and the issuer is unable to accurately measure and estimate the amount and time of payment of F103 product technology licensing fee at the time of delivery of F103 product technology, the issuer intends to make a decision according to the R & D Progress of subsequent F103 engineering samples and mass production, Relevant accounting treatment shall be carried out after the amount and time of F103 authorization payment are determined.

(2) Adjustment on accounting treatment of F103 product technology authorization fund

Although the issuer cannot accurately measure and estimate the amount and time of payment of F103 product technology licensing fee at the time of delivery of F103 product technology, considering that Wuhan Xinxin has delivered F103 product technology related materials to the issuer, in order to fully reflect the transaction in the financial statements, The issuer has provisionally estimated that the F103 product technology authorization fund of 20 million yuan has been included in the accounting of other non current assets according to the contract amount, and the provisionally estimated payable F103 product technology authorization fund of 20 million yuan has been included in the accounting of other non current liabilities.

The issuer has adjusted the relevant statement items, and the relevant adjustments have no impact on the net assets and net profits of the issuer in each period of the reporting period. The corrected accounting treatment complies with the relevant provisions of the accounting standards for business enterprises. The issuer adjusted the financial statements from January to June 2021 according to the above matters, as follows:

Unit: 10000 yuan

Amount before and after adjustment of financial statement items

Other non current assets 186.04 2000.00 2186.04

Other non current liabilities – 2000.00 2000.00

The correction to the accounting treatment of F103 Product Authorization fund is not caused by the company’s weak accounting basis, major defects in internal control, earnings manipulation, major accounting omissions without timely audit adjustment, abuse of accounting policies or accounting estimates, malicious concealment or fraud, and does not have a direct impact on the company’s daily operation. This correction and adjustment does not intentionally omit or fabricate transactions, events or other important information, abuse accounting policies or accounting estimates, manipulate, forge or tamper with the accounting records on which the financial statements are prepared, and does not constitute a situation in which the company does not meet the issuance conditions in terms of basic accounting standards and relevant internal control, Comply with the relevant provisions of the accounting standards for business enterprises and answers to some questions about initial business.

The company held the seventh meeting of the first board of directors on January 28, 2022, deliberated and approved the proposal on correcting the company’s financial statements from 2018 to January June 2021, and corrected the accounting treatment of F103 Product Authorization fund.
