Important Risks: Investing involves risk, including the possible loss of principal. Security prices fluctuate in value depending on general market and economic conditions and the prospects of individual companies. • Risks of focusing investments on the healthcare related sector include regulatory and legal developments, changes in funding or subsidies, patent and intellectual property considerations, intense competitive pressures, rapid technological changes, long and costly process for obtaining product approval by government agencies, potential product obsolescence, rising cost of medical products and services, and price volatility risk. • Small- and mid-cap securities can have greater risks and volatility than large-cap securities. • Foreign investments may be more volatile and less liquid than U.S. investments and are subject to the risk of currency fluctuations and adverse political, economic and regulatory developments. These risks may be greater, and include additional risks, for investments in emerging markets.
