EUOSHA/2021/OP/F/SE/0142  (together or alone), or a copy of the publication of such appointment if the legislation that applies to  signatory requires such publication or a power of attorney). A document that the  contracting authority can access on a national database free of charge does not need to be submitted if the  contracting  authority  is provided with the exact internet link and, if applicable, the necessary identification data to  retrieve the document.  Once the  contracting authority has opened a tender, it becomes its property and shall be treated  confidentially, subject to the following:  5.4  Confidentiality of tenders  • The  contracting authority may disclose the submitted tender in the context of a request for  public access to documents, or in other cases where the applicable law requires its disclosure.  Unless there is an overriding public interest in disclosure, 7  the  contracting authority  may refuse  to provide full access to the submitted tender, redacting the parts (if any) that contain  confidential information, the disclosure of which would undermine the protection of commercial  interests of the tenderer, including intellectual property. • After the signature of the award decision, tenderers whose tenders were received in  accordance with the submission modalities, who have access to procurement, who are not  found to be in an exclusion situation referred to in Article 136(1) of the Financial Regulation,  who are not rejected under Article 141 of the Financial Regulation, whose tenders are not found  to be incompliant with the procurement documents, and who make a request in writing, will be  notified of the name of the tenderer to whom the contract is awarded, the characteristics and  relative advantages of the successful tender and the price of the offer and/or contract value.  The  contracting authority  may decide to withhold certain information that it assesses as being  confidential, in particular where its release would prejudice the legitimate commercial interests  of economic operators or might distort fair competition between them. Such information may  include, without being limited to, confidential aspects of tenders such as unit prices included in  the financial offer, or technical or trade secrets. 6 • For the purposes of evaluating the tender and, if applicable, implementing the contract,  performing audits, benchmarking, etc., the  contracting authority  is entitled to make available  (any part of) the tender to its staff and the staff of other Union institutions, agencies and bodies,  as well as to other persons and entities working for the  contracting authority  or cooperating with  it, including contractors or subcontractors and their staff, provided that they are bound by an  obligation of confidentiality.  7  See Article 4(2) of Regulation (EC) No 1049/2001 regarding public access to European Parliament, Council and Commission  documents.  6  For the definition of trade secrets please see Article 2(1) of Directive (EU) 2016/943 on the protection of undisclosed know-how  and business information (trade secrets) against their unlawful acquisition, use and disclosure.    The  contracting authority  will disregard general statements that the whole tender or substantial parts  of it contain confidential information. Tenderers need to mark clearly the information they consider  confidential and explain why it may not be disclosed. The  contracting authority  reserves the right to  make its own assessment of the confidential nature of any information contained in the tender. 83
