Investor Relations (IR) ≠ Public Relations (PR)

Click on the links above to see how Wikipedia defines these terms. In short:

• Investor Relations (IR) is a strategic management responsibility that is capable of integrating finance, communication, marketing and securities law compliance to enable the most effective two-way communication between a company, the financial community, and other constituencies, which ultimately contributes to a company's securities achieving fair valuation.
• Public relations (PR) is the practice of managing the spread of information between an individual or an organization and the public. Public relations may include an organization or individual gaining exposure to their audiences using topics of public interest and news items that do not require direct payment. The aim of public relations is to persuade the public, prospective customers, investors, partners, employees, and other stakeholders to maintain a certain point of view about it, its leadership, products, or of political decisions.

Chris Chu is responsible for Investor Relations, not for Public Relations. Important difference!
