Harbor Global Growth Fund Investor Class (HGGIX)

Investment Philosophy

Principal Style Characteristics: Companies throughout the world selected for long-term growth potential

The Fund invests primarily in common stocks of U.S. and foreign companies that are selected for their long-term growth potential. The Fund may invest in companies of any size that are economically tied to any countries or markets throughout the world, including companies economically tied to emerging markets. Under normal market conditions, the Fund invests significantly (generally, at least 40% of its net assets) in the securities of issuers economically tied to foreign countries (unless market conditions are not deemed favorable by the Subadviser, in which case the Fund generally will invest less than 40%, but at least 30%, of its assets in such foreign securities). The Fund will invest its assets in various regions and countries, including the U.S., that encompass not less than three different countries overall.

In selecting investments for the Fund, the Subadviser uses an approach that combines "top-down" macro-economic analysis with "bottom-up" security selection. The "top-down" approach may take into consideration macro-economic factors such as, without limitation, interest rates, inflation, monetary policy, fiscal policy, currency movements, demographic trends, the regulatory environment and the global competitive landscape. The Subadviser may also examine other factors that may include, without limitation, the most attractive global investment opportunities, industry consolidation and the sustainability of financial trends. Through this "top-down" analysis, the Subadviser seeks to identify sectors, industries and companies that may benefit from the overall trends the Subadviser has observed.

The Subadviser then looks for individual companies or securities (including, without limitation, equity securities and fixed or variable income securities) that are expected to offer earnings growth potential that may not be recognized by the market at large. In determining whether a particular company or security may be a suitable investment, the Subadviser may focus on any of a number of different attributes that may include, without limitation, the company's specific market expertise or dominance; its franchise durability and pricing power; solid fundamentals (e.g., a strong balance sheet, improving returns on equity, the ability to generate free cash flow, apparent use of conservative accounting standards, and transparent financial disclosure); strong and ethical management; commitment to shareholder interests; reasonable valuations in the context of projected growth rates; current income; and other indications that a company or security may be an attractive investment prospect. This process is called "bottom-up" security selection.

As part of this fundamental, "bottom-up" research, the Subadviser may visit with a company's management and conduct other research to gain thorough knowledge of the company. The Subadviser also may prepare earnings and cash flow models of companies. These models may assist the Subadviser in projecting potential earnings growth, current income and other important company financial characteristics under different scenarios. Each model is typically customized to follow a particular company and is generally intended to replicate and describe a company's past, present and potential future performance. The models may include quantitative information and narratives that reflect current interpretations of corporate data and company and industry developments. The core investments of the Fund (i.e., the primary investments held by the Fund over time) generally may include established companies and securities that are expected to offer long-term growth potential. However, the Fund's portfolio also may include securities of less mature companies, securities with more aggressive growth characteristics, and securities of companies undergoing significant positive developments, such as, without limitation, the introduction of a new product line, the appointment of a new management team, or an acquisition.

The Subadviser may reduce or sell the Fund's investments in portfolio securities if, in the opinion of the Subadviser, a security's fundamentals change substantially, its price appreciation leads to substantial overvaluation in relation to the Subadviser's estimates of future earnings and cash flow growth, or for other reasons.

Risks

There is no guarantee that the investment objective of the Fund will be achieved. Stocks fluctuate in price and the value of your investment in the Fund may go down. This means that you could lose money on your investment in the Fund or the Fund may not perform as well as other possible investments. Principal risks include:

Market and Issuer risk: Securities markets are volatile and can decline significantly in response to adverse market, economic, political or regulatory developments, which may lower the value of securities held by the Fund, sometimes rapidly or unpredictably. Additionally, an adverse event, such as an unfavorable earnings report, may depress the value of a particular issuer's stock.

Growth style risk: Over time, a growth oriented investing style may go in and out of favor, which may cause the Fund to underperform other equity funds that use different investing styles.

Selection risk: The Subadviser's judgment about the attractiveness, value and potential appreciation of a particular security may be incorrect.

Foreign securities risk: Because the Fund invests primarily in securities of foreign issuers, an investment in the Fund is subject to special risks in addition to those of U.S. securities. These risks include heightened political and economic risks, greater volatility, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. Foreign securities are sometimes less liquid and harder to value than securities of U.S. issuers. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. If foreign securities are denominated and traded in a foreign currency, the value of the Fund's foreign holdings can be affected by currency exchange rates and exchange control regulations. The Fund's investments in foreign securities may also be subject to foreign withholding taxes.

The 2008 global economic crisis brought several European governments close to bankruptcy and many other economies into recession and weakened the banking and financial sectors of many countries. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market.

Emerging market risk: Foreign securities risks are more significant in emerging market countries, such as those in Eastern Europe, Latin America and the Pacific Basin. These countries may have relatively unstable governments and less-established market economies than developed countries. Emerging markets may face greater social, economic, regulatory and political uncertainties. These risks make emerging market securities more volatile and less liquid than securities issued in more developed countries.
