请老师解释一下A选项，七个原则里没找到engagement

嗨，努力学习的PZer你好：

The 2010 Stewardship Code had seven principles: Institutional investors should

1. publicly disclose their policy on how they will discharge their stewardship

responsibilities;

2. have a robust policy on managing conflicts of interest in relation to stewardship

and this policy should be publicly disclosed;

3. monitor their investee companies;

4. establish clear guidelines on when and how they will escalate their activities

as a method of protecting and enhancing shareholder value;

5. be willing to act collectively with other investors where appropriate;

6. have a clear policy on voting and disclosure of voting activity; and

7. report periodically on their stewardship and voting activities.

engagement（参与）和escalation（升级）分别对应第一条和第四条
