Harbor Money Market Fund Administrative Class (HRMXX)

Investment Philosophy

Principal Style Characteristics: Very short-term high quality money market instruments

The Fund invests in U.S. dollar-denominated money market securities. These may include obligations issued by:

  • U.S. government and its agencies and instrumentalities
  • U.S. states and municipalities
  • U.S. and foreign banks
  • Corporate issuers
  • Foreign governments
  • Multinational organizations such as the World Bank

The Subadviser selects securities for the Fund's portfolio by:

  • Allocating assets and actively trading among issuer sectors, such as U.S. treasuries, corporate issuers, U.S. government agencies, etc., while focusing on sectors that appear to have the greatest near-term return potential.
  • Focusing on securities that appear to offer the best relative value based on an analysis of their credit quality and interest rate sensitivity.

The Fund may invest more than 25% of its assets in securities in the banking industry. The Fund may invest in all types of money market securities, including commercial paper, certificates of deposit, bankers' acceptances, mortgage-backed and asset-backed securities, repurchase agreements and other short-term debt securities.

Minimum Credit Quality. At least 95% of the Fund's investments are rated in the rating agencies' highest short-term rating category or are unrated securities the Subadviser determines to be of equivalent quality.

Maximum Maturity. The Fund maintains a dollar-weighted average maturity (WAM) of 60 days or less and a dollar-weighted average life (WAL) of 120 days or less. The securities held in the Fund's portfolio have remaining maturities of 397 days or less. The weighted average maturity of the Fund's portfolio was 47 days as of December 31, 2014.

Risks

There is no guarantee that the investment objective of the Fund will be achieved. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund. Principal risks include:

Interest rate risk: As interest rates rise, the values of fixed income securities held by the Fund are likely to decrease and reduce the value of the Fund's portfolio. Additionally, rising interest rates may lead to increased redemptions, increased volatility and decreased liquidity in the fixed income markets, making it more difficult for the Fund to sell its fixed income holdings when the Subadviser may wish to sell or must sell to meet redemptions.

Credit risk: The issuer or guarantor of a security owned by the Fund could default on its obligations to pay principal or interest or its credit rating could be downgraded. Likewise, a counterparty to a derivative or other contractual instrument owned by the Fund could default on its obligation.

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

Foreign securities risk: Because the Fund may invest 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 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. 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.

Industry concentration risk: The Fund may invest more than 25% of its assets in securities in the banking industry. As a result, the Fund's performance may depend to a large extent on the overall condition of that industry.

Regulatory risk:The Securities and Exchange Commission recently adopted changes to the rules that govern money market funds. These changes will: (1) permit, subject to the discretion of the Board of Trustees, money market funds to impose a "liquidity fee" (up to 2%) and/or "gates" that temporarily restrict redemptions from the funds, if weekly liquidity levels fall below the required regulatory threshold, and (2) require "institutional" money market funds to operate with a floating NAV rounded to the fourth decimal place. "Government money market funds," which are money market funds that limit their investments to cash, U.S. Government Securities, and/or repurchase agreements that are collateralized fully, are exempt from these requirements. These changes may affect the Fund's investment strategies, operations and/or return potential. As of the date of this Prospectus, the Adviser is evaluating the potential impact of these changes which have a phase in compliance period ranging from July 2015 through October 2016.

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 or adverse economic conditions may depress the value of a particular issuer's securities or may increase the risk that issuers will not generate sufficient cash flow to service their debt obligations.

Stable net asset value risk: The Fund may not be able to maintain a net asset value ("NAV") per share of $1.00 at all times. If any money market fund fails to maintain a stable NAV (or if there is a perceived threat of such a failure), other money market funds, including the Fund, could be subject to increased redemption activity, which may adversely affect the Fund's NAV. Shareholders of the Fund should not rely on or expect the Adviser or an affiliate to purchase distressed assets from the Fund, make capital infusions into the Fund, enter into capital support agreements with the Fund or take other actions to help the Fund maintain a stable $1.00 share price.

An investment in the Harbor Money Market Fund is not guaranteed by the FDIC or any other government agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.
