中信证券股份有限公司关于苏州联讯仪器股份有限公司使用募集资金置换预先投入募投项目的自筹资金及已支付发行费用的核查意见
Regulatory Filings Classification · 95% confidence The document is a sponsor’s due diligence and verification opinion on the use of IPO proceeds to replace pre-invested own funds and paid issuance expenses. It consists of legal and regulatory attestation by the sponsor (with accountant verification) rather than the actual issuance of a financial report (e.g., annual or quarterly report). Under the certification rule, such officer/sponsor attestations are classified as a general regulatory filing. Therefore, it is coded as RNS (Regulatory Filings).
