Examples

The following examples are intended to help you compare the cost of investing in the Fund’s Investor Shares or Admiral Shares with the cost of investing in other mutual funds. They illustrate the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund’s shares. These examples assume that the Shares provide a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year	3 Years	5 Years	10 Years
Investor Shares	$36	$113	$197	$443
Admiral Shares	$31	$97	$169	$381

 

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense examples, reduce the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 8%.

Primary Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its assets in the stocks of companies principally engaged in the development, production, or distribution of products and services related to the health care industry. These companies include, among others, pharmaceutical firms, medical supply companies, and businesses that operate hospitals and other health care facilities. The Fund also considers companies engaged in medical, diagnostic, biochemical, and other research and development activities. The Fund’s advisor strives for a balanced representation of the health care field, searching for the best values in the various subsectors of the industry. The Fund may invest up to 50% of its assets in foreign stocks.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund’s share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. The Fund is subject to the following risks, which could affect the Fund’s performance:

• Industry concentration risk , which is the chance that there will be overall problems affecting a particular industry. Because the Fund normally invests at least 80% of its assets in the stocks of companies related to the health care industry, the Fund’s performance largely depends—for better or for worse—on the overall condition of this industry. The health care industry could be adversely affected by various political, regulatory, supply-and-demand, and other economic factors.

• Stock market risk , which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. In addition, investments in foreign stocks can be riskier than U.S. stock investments. The prices of foreign stocks and the prices of U.S. stocks have, at times, moved in opposite directions.

• Manager risk , which is the chance that poor security selection will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.

• Country risk , which is the chance that world events—such as political upheaval, financial troubles, or natural disasters—will adversely affect the value of securities issued by companies in foreign countries.

• Currency risk , which is the chance that the value of a foreign investment, measured in
U.S. dollars, will decrease because of unfavorable changes in currency exchange rates.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are shown only for the Investor Shares and may differ for each share class. After-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.
