commission一词，大家并不陌生，一般而言，其在法律文件中有三层含义：

1.佣金

any payment by any Group Company or any Associated Company of any professional fees or other transaction costs, expenses or bonuses to any person (including any advisory, consulting or management fees or commissions) in connection with the preparation for, negotiation, agreement, consummation or communication of the transactions contemplated in this Agreement; 

任一集团公司或任一联属公司就与本协议项下拟进行交易的准备、谈判、协议、完成或沟通向任何人支付的专业人员费或其它交易成本、费用或奖金（包括任何顾问、咨询、管理费或佣金）

2.委员会

这层含义在法律文件中比较常见，很基础也很简单：

比如permanent commission（常务委员会）；美国证券交易监督委员会(U.S. Securities and Exchange Commission)等等

这里给大家普及一下commission与committee的区别：

commission: a group of people etrusted by a goverment or other official body with authority to do something

committee: a group of people are appointed for a specific fuction by a larger group and typically consisting of members of that group.
