Private M&A transactions, whether they be for the sale and purchase of a company or a business, are concluded by way of an exchange (or signing) of contracts and completion (or closing) of the transaction. At exchange, the parties sign and execute the formal documentation for the transaction, including a share purchase agreement or asset purchase agreement. At completion, the requisite formalities to complete and implement the transaction are undertaken, including delivery of title certificates (shares or other) and other assets. Exchange and completion may occur simultaneously or may be split, depending on whether the agreement for the transaction is unconditional or conditional, respectively. In addition, exchange and completion may occur in face-to-face meetings or virtually (via telephone, email or other electronic means of communication). For further information, see Practice Note: Issues arising where there is split exchange and completion—share and asset purchases. This document provides practical guidance on requirements for exchange and completion, and on the legal and practical issues to be considered by solicitors leading up to and at exchange
