abstract:Data rooms (online data room) are used in many different types of transactions where the vendor (in the case of a property, M&A or share sale) or the authority (in the case of a PFI/PPP project) wishes to disclose a large amount of confidential data to proposed bidders typically during the due diligence process. The traditional data room will literally be a physically secure continually monitored room, normally in the vendor’s offices (or those of their lawyers), which the bidders and their advisers will visit in order to inspect and report on the various documents and other data made available.
