The performance data quoted represents past performance. Past performance does not guarantee future results. The Fund’s principal value, share price, yields, rates and total returns will vary due to changing market conditions, so that shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted. To obtain performance data current to the most recent month-end, an investor may call toll free at 800-276-1262.

Investments are not FDIC-insured, nor are they deposits of or guaranteed by a bank or any other entity, so they may lose value.

Because the Fund normally invests in common stocks of companies engaged in natural resources-related activities in a limited geographical area, the Fund’s performance largely depends on the overall economic condition of the related sectors and geographical area. Additionally, diplomatic, political or economic developments in foreign countries could adversely impact the Fund’s investment in securities of foreign companies.

For more information about the risks associated with the fund, please read carefully the fund’s prospectus.

Morningstar Ratings: For each fund with at least a 3-year history, Morningstar calculates a risk-adjusted return measure that accounts for variation in a fund's monthly performance (excluding sales charges and including fees and expenses versus all funds in the Morningstar category), placing more emphasis on downward variations and rewarding consistent performance. These ratings change monthly. The top 10% of funds in each category receive a Morningstar Rating™ of 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund and rated separately.) Past performance does not guarantee future results.
