Accounting for 1.56%, 0.90%, 10.31%, 2.13%, 0.12%, 0.18% of operating revenue

During the reporting period, the company sold fewer products without installation and commissioning, and the overall proportion was relatively low.

The products that do not need installation and commissioning are mainly the centralized purchased products used for China’s anti epidemic and international assistance during the epidemic period, as well as the sales of products signed with some large overseas dealers that do not need the company to be responsible for installation and commissioning. There is no need to install and debug. The sales agreement stipulates that the buyer will complete the delivery of products after signing, and the company will recognize the income accordingly.

(II) under the distribution and direct selling mode, the main links, time cycle, main performance obligations of the issuer in each link from the signing of the contract to the recognition of revenue, the differences between the installation and commissioning link and the final acceptance link, the amount and proportion of revenue recognized according to different methods, and whether the revenue recognized in the initial inspection stage complies with the accounting standards for business enterprises and industry practices

Main link time period main performance obligations of the issuer

After signing the contract 1-7 days after delivery / arrival, the issuer will arrange logistics to transport the goods to the destination agreed in the contract (usually the equipment installation site of the end user) according to the customer’s requirements.

In August of CT products, the issuer arranged engineers to complete the hardware assembly and software and hardware debugging of the equipment on site. The specific package of MI products in June and July includes:

Installation and commissioning of Mr products 1. On July 1, the issuer’s engineers completed the installation of the equipment according to the installation and commissioning procedures of different product standards; On February 2, 0 of RT products, the issuer’s engineers tested each performance index of the equipment item by item, and recorded each work item by item in the report of installation and commissioning record. During commissioning, the possible problems were solved by assembling XR products, adjusting and replacing accessories in January and March.

The report of “installation and commissioning record” details the installation work contents and corresponding results of the product, including whether the physical appearance inspection, installation tool inspection, physical installation, system configuration and commissioning and other parameters meet the standards. All equipment status, output parameters and other indicators are within the normal range of the enterprise’s product description (reaching the enterprise standard), which shall be signed and confirmed by the issuer’s engineer on site. The clinical engineer of the end user (hospital) shall inspect the physical appearance, spare parts and system parameter performance of the equipment and complete the handover of product data at the same time, and then sign on the installation and commissioning record report, which shall be signed and confirmed by the procurement or user department of the end user.

According to the sales contract signed between the issuer and the distributor, the issuer will complete the product delivery obligation to the distributor’s customers immediately after the installation and commissioning, and the control of the products will be transferred to the customers at this point. The issuer recognizes the product sales revenue at this point.

After the installation and commissioning is completed, the company needs to carry out corresponding equipment operation training for end users (mainly hospital technicians) according to the contract. The training time required for each product type varies, usually 2 to 10 days. According to the contract, training does not constitute the premise of completing the obligation of product delivery, and the company’s limited investment in product training (mainly the on-site time and travel investment of Engineers) does not constitute a major separate obligation to perform the contract. Therefore, the training link does not have a significant impact on the revenue recognition of the company.
