The Rules build upon Principles 3 and 9 of the Principles of Business (see Module PB (Principles of Business)). Principle 3 (Due Skill, Care and Diligence) requires an investment firm licensee to observe high standards of integrity and fair dealing, and to be honest and straightforward in its dealings with clients. Principle 9 (Adequate Resources) requires an investment firm licensee to maintain adequate human, financial and other resources sufficient to run its business in an orderly manner.
