Invesco Advisers, Inc. (Sub-Adviser) primarily looks for quality companies, regardless of domicile, that have sustainable growth. The Sub-Advisers investment approach combines a thematic approach to idea generation with bottom-up, fundamental company analysis. The Sub-Adviser seeks to identify secular changes in the world and looks for pockets of durable change that the Sub-Adviser believes will drive global growth for the next decade. These large scale structural themes are referred to collectively as MANTRA : Mass Affluence, New Technology, Restructuring, and Aging. The Sub-Adviser does not target a fixed allocation with regard to any particular theme, and may choose to focus on various sub-themes within each theme. Within each sub-theme, the Sub-Adviser employs fundamental company analysis to select investments for the Funds portfolio. The economic characteristics the Sub-Adviser seeks include a combination of high return on invested capital, good cash flow characteristics, high barriers to entry, dominant market share, a strong competitive position, talented management, and balance sheet strength that the Sub-Adviser believes will enable the company to fund its own growth. These criteria may vary. The Sub-Adviser also considers how industry dynamics, market trends and general economic conditions may affect a companys earnings outlook. The Sub-Adviser has a long-term investment horizon of typically three to five years. The Sub-Adviser also has a contrarian buy discipline; the Sub-Adviser buys common stocks of high-quality companies that fit the Sub-Advisers investment criteria when the Sub-Adviser believes the valuations, at the time of purchase, underestimate what the Sub-Adviser believes are their long-term earnings potential. For example, a companys stock price may dislocate from its fundamental outlook due to a short-term earnings glitch or negative, short-term market sentiment, which can give rise to what the Sub-Adviser believes is an attractive investment opportunity. The Sub-Adviser monitors individual issuers for changes in earnings potential or other effects of changing market conditions that may trigger a decision to sell a security, but do not require a decision to do so.
