Participating creditor countries and the debtor country usually sign an Agreed Minute at the end of a negotiation session. This is not a legally binding document, but a recommendation by the heads of delegations of Participating creditors countries to their governments to sign a bilateral agreement implementing the debt treatment. When there are only a few creditors concerned, the Paris Club agreement is exchanged through mail between the Chair of the Paris Club and the government of the debtor country, and is called "terms of reference". In some cases, the multilateral debt agreement has also been called "memorandum of understanding".
