In contract law and business law, "novation"〔(【引用サイトリンク】title=Derivatives Overview )〕 is the act of either: # replacing an obligation to perform with another obligation; or # adding an obligation to perform; or # replacing a party to an agreement with a new party. In contrast to an assignment, which is valid so long as the obligee (person receiving the benefit of the bargain) is given notice, a novation is valid only with the consent of all parties to the original agreement: the obligee must consent to the replacement of the original obligor with the new obligor. A contract transferred by the novation process transfers all duties and obligations from the original obligor to the new obligor. For example, if there exists a contract where Dan will give a TV to Alex, and another contract where Alex will give a TV to Becky, then, it is possible to novate both contracts and replace them with a single contract wherein Dan agrees to give a TV to Becky. Contrary to assignment, novation requires the consent of all parties. Consideration is still required for the new contract, but it is usually assumed to be the discharge of the former contract. Another classic example is where Company A enters a contract with Company B and a novation is included to ensure that if Company B sells, merges or transfers the core of their business to another company, the new company assumes the obligations and liabilities that Company B has with Company A under the contract. So in terms of the contract, a purchaser, merging party or transferee of Company B steps into the shoes of Company B with respect to its obligations to Company A. Alternatively, a "novation agreement" may be signed after the original contract in the event of such a change. This is common in contracts with governmental entities; an example being under the United States Anti-Assignment Act, the governmental entity that originally issued the contract must agree to such a transfer or it is automatically invalid by law. The criteria for novation comprise the obligee's acceptance of the new obligor, the new obligor's acceptance of the liability, and the old obligor's acceptance of the new contract as full performance of the old contract. Novation is not a unilateral contract mechanism, hence allows room for negotiation on the new T&Cs under the new circumstances. Thus, 'acceptance of the new contract as full performance of the old contract' may be read in conjunction to the phenomenon of 'mutual agreement of the T&Cs.〔 ==Application in financial markets== (Novation ) is also used in futures and options trading to describe a special situation where the central clearing house interposes itself between buyers and sellers as a legal counter party, i.e., the clearing house becomes buyer to every seller and vice versa. This obviates the need for ascertaining credit-worthiness of each counter party and the only credit risk that the participants face is the risk of the clearing house defaulting. In this context, novation is considered a form of risk management. The term is also used in markets that lack a centralized clearing system, such as swap trading and certain over-the-counter (OTC) derivatives, where "novation" refers to the process where one party to a contract may assign its role to another, who is described as "stepping into" the contract. This is analogous to selling a futures contract. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「novation」の詳細全文を読む スポンサード リンク
