1. Reasons and rationality for the continuous low level of capacity utilization

The company strives to develop new markets and new customers, but the development requires time accumulation and capital support. Due to the great changes in the company’s internal environment and the shortage of funds required for operation, the company’s business development is less than expected. The main reasons for the company’s low capacity utilization in 2021 are as follows:

(1) The internal environment of the company has changed greatly

In 2021, the internal environment of the company changed greatly. During the running in period when the new management and management were involved in the management, the sales work of the company was affected to a certain extent.

While serving as the controlling shareholder and actual controller of the company, happy Holding Group Co., Ltd. and Gao Changhong signed loan contracts and guarantee contracts with creditors in the name of the company without the internal approval process and relevant decision-making procedures of the company. They borrowed money in the name of the company or the company assumed joint and several guarantee liabilities for the financing behavior of Gao Changhong and the company controlled by Gao Changhong. On and after November 2019, the company successively received the notice of responding to the lawsuit from relevant courts, and the relevant creditors asked the company to repay or assume joint and several guarantee liabilities for the arrears of Gao Changhong and the company controlled by Gao Changhong. The company paid the corresponding amount due to losing the lawsuit and mediation, and the bank account of the company was frozen by the creditor in 2021. In addition, the net cash flow from the company’s operating activities in 2021 decreased, and some banks required the company to repay the due short-term loans. The above matters strained the funds required for the company’s operation and had a certain impact on the company’s production and operation.

(3) Transformation of special equipment of the company

In order to better meet the production demand of products, the company updated and transformed some special machines and equipment in 2021, and the original value of the special equipment involved in the transformation was 124066 million yuan. The renewal and transformation time is generally more than half a year, and production cannot be carried out during the transformation, which has a certain impact on the production and operation of the company.

To sum up, in 2021, due to the changes in the company’s internal environment, the shortage of funds required for operation, the freezing of some bank accounts and the transformation of special equipment, the company’s business development was less than expected. The company has fewer sales orders in 2021, resulting in low capacity utilization.

2. Whether the production equipment related to the above products has fully accrued the impairment provision, and whether it is still necessary to further accrue the impairment provision

The capacity utilization of the company’s production line is as follows:

Number of production lines of main products location design capacity (ton) capacity utilization (piece)

Special polyethylene and crosslinked polysilane workshop 3000000 60.00% ethylene cable material

PVC cable material 4500000 40.00% 8 PVC workshop

Rubber plastic modified elastomer 100000 10.00%

Halogen free low smoke flame retardant cable material 4 halogen free low smoke workshop 1000000 30.00%

Rubber cable material 2 rubber workshop 300000 5.00%

The company’s main products are polymer linear materials for cables. Wires and cables are indispensable basic equipment for transmitting electric energy, transmitting information, manufacturing various motors, instruments and meters, and realizing electromagnetic energy conversion. They are necessary basic products in the electrification and information society. The support of national policies and the development of market demand have a positive impact on the company’s development of new markets and new products.

(1) Relevant production lines of special polyethylene and cross-linked polyethylene cable materials

As shown in the above table, the silane workshop of the company’s new plant has six production lines, which are mainly used to produce special polyethylene and cross-linked polyethylene cable materials. The capacity utilization rate of relevant production lines in 2021 is 60%, which is high. Special polyethylene and cross-linked polyethylene cable materials are the main products of the company. The newness rate of relevant production lines is high, the market price has not decreased significantly, and there is no obvious sign of impairment.

(2) Production line of PVC cable material and rubber plastic modified elastomer

As shown in the above table, the PVC workshop of the company’s new plant has eight production lines, and the products produced include PVC cable material and rubber plastic modified elastomer. Rubber plastic modified elastic system is a kind of cable material between rubber and plastic. Its production process is similar to that of PVC cable material. PVC cable material and rubber plastic modified elastomer can share the production line. In 2021, the operating revenue of the above products increased by 5% over the previous year, and the sales situation has improved. However, the capacity utilization rate of the company’s production line is still low, and the eight production lines can not operate at full capacity. In 2021, the above eight production lines were in good condition and not idle, and the corresponding market prices did not fall significantly, and there was no obvious sign of impairment.

(3) Relevant production lines of halogen-free low smoke flame retardant cable materials

As shown in the above table, the company’s halogen-free low smoke workshop has four production lines, three domestic internal mixing production lines and one imported bussag production line located in the new plant area.

1) Three domestic internal mixing production lines in the new plant area of the company

There are two domestic internal mixing production lines in the new plant area of the company, which have reached the expected serviceable state in July 2019 and July 2020 respectively. The two domestic internal mixing production lines can produce normally, and the assets are in good condition and not idle, without obvious signs of impairment. A domestic internal mixing production line in the original old plant has been transferred to the new plant. The company repaired and debugged some old equipment and reassembled them with new equipment. In 2019, the company entrusted an asset appraisal institution to evaluate this part of old equipment and accrued corresponding assets according to the appraisal results
