This price information includes concluded transaction prices, the enterprise's expected most likely pending transaction prices, etc. All instant messaging content, email communications, and any records of face-to-face communications will be archived details of phone communications will be recorded and entered into the database. SMM analysts must comply with the Compliance System when reporting any forced or threatened communications from market participants, or any induced offers attempting to influence the assessment. Once published, SMM will not revise or adjust the price on the same day. 2.2.9.1 Assessment (Calculation) of Published Prices Step-1: The final dataset from the previous chapter, which exists as a processing fee range, is split into several lower limit values and several upper limit values for two different types of enterprise classifications in this methodology version: copper foil producers and downstream end-users. Arithmetic averages are calculated for both sets and rounded to the nearest whole number. Among these: - When both transaction information and offer/counteroffer information are present, the weight of transaction information is set at 60%, and offer/counteroffer information at 40%. - When transaction information, offer/counteroffer information, and other information are all present, the weight of transaction information is set at 50%, offer/counteroffer information at 40%, and other information at 10%. - When only offer/counteroffer information and other information are present, the weight of offer/counteroffer information is set at 90%, and other information at 10%. Step-2: The two price ranges derived from the previous step, which exist as processing fee states, are split into two lower limit values and two upper limit values. Weights are applied, and weighted averages are calculated, then rounded to the nearest whole number. In this methodology version, copper foil producers are weighted at 60%, and downstream enterprises at 40%. Step-3: The relevant calculation coefficients above will be adjusted every six months to ensure timeliness. 2.2.9.2 Data Standardization Although SMM has standardized definitions for our prices, diversity exists in market transactions. The price of each transaction is influenced by numerous factors, including order size, brand of goods, delivery time, payment terms, etc. SMM will comprehensively consider market offers, bids, and transaction information, aligning them with our standards.
