  William Blair International - Financial Reporting Council's UK Stewardship Code Disclosure

  Under Rule 2.2.3R of the FSA's Conduct of Business Sourcebook, William Blair International ("WBI") is required to include a disclosure about the nature of its commitment to the UK Financial Reporting Council's Stewardship Code (the "Code") or, where it does not commit to the Code, its alternative investment strategy. The Code is a voluntary code and sets out a number of principles relating to engagement by investors with UK equity issuers. Investors that commit to the Code can either comply with it in full or choose not to comply with aspects of the Code, in which case they are required to explain their non compliance. We have detailed below the reasons why WBI has chosen not to commit to the Code.

  WBI pursues a long only global equity strategy that involves it investing in global equities, including UK equities. The Code is therefore relevant to some aspects of WBI's trading. While WBI generally supports the objectives that underlie the Code, WBI has chosen not to commit to the Code. WBI invests in a variety of asset classes and in a variety of jurisdictions globally. The policies of the WBI in relation to engagement with issuers and their management are determined globally. WBI takes a consistent global approach to engagement with issuers and their management in all of the jurisdictions in which it invests and, consequently, does not consider it appropriate to commit to any particular voluntary code of practice relating to any individual jurisdiction.
