Harbor Core Bond Fund Institutional Class (HACBX)

Investment Strategy

The Fund invests primarily in investment-grade fixed income securities of issuers located in the U.S. Under normal market conditions, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in a diversified portfolio of fixed income instruments. Fixed income instruments include bonds, debt securities and other similar instruments issued by various public- or private-sector entities.

The Subadviser's approach is grounded in detailed bottom-up research and emphasizes careful security selection through:

  • Rigorous fundamental credit analysis of the issuer,
  • A detailed review of the structural features of the security, and
  • Relative-value comparisons to other opportunities.

In order to be selected for the portfolio, a security must be attractive on all three of these factors. If one factor deteriorates, the security becomes a candidate for sale.

When forming an opinion on the creditworthiness of an issuer, the Subadviser evaluates many factors, including financial performance, balance sheet strength, management quality, operating risk, market position, industry fundamentals, event risk, and economic sensitivity. For securitized bonds (such as mortgage-backed and asset-backed), the Subadviser assesses factors such as issue sponsorship, structure, deal history, regulation, and liquidity. The Subadviser's analysis also includes a detailed review of the underlying structural features of a bond, such as coupon type, redemption features, level of subordination, and collateral.

The Subadviser believes that it is difficult to predict the timing, direction, and magnitude of future interest-rate changes. Therefore, duration management and yield-curve positioning are not part of the Fund's strategy.

The portfolio is constructed from the bottom up and is comprised of U.S. dollar-denominated securities. The Subadviser sets sector allocations based on its views of relative values between sectors and opportunities at the security level. A comprehensive risk overlay also influences portfolio construction. The Subadviser systematically measures and monitors the Fund's key risk exposures. The overall aim of the portfolio construction process is to craft a portfolio of attractively priced securities (relative to other opportunities in the universe) that when combined together in a portfolio provide what the Subadviser believes will be attractive expected return, reasonable risk exposures, and adequate liquidity.

At times, the Fund may invest a large percentage of its assets in investment-grade mortgage-backed and asset-backed securities.

Credit Quality: The Fund invests primarily in investment-grade securities.

Duration: The Fund's average duration, as calculated by the Subadviser, is normally equal to that of its benchmark, plus or minus 10%. The duration of the Bloomberg Barclays U.S. Aggregate Bond Index as of December 31, 2017 was 5.98 years. Average duration is a weighted average of all bond durations in the Fund's portfolio, and is an approximate measure of the sensitivity of the market value of the Fund's holdings to changes in interest rates. If the Fund's duration is longer than the market's duration, the Fund would be expected to experience a greater change in the value of its assets when interest rates are rising or falling than would the market as a whole.


There is no guarantee that the investment objective of the Fund will be achieved. Fixed income securities fluctuate in price in response to various factors, including changes in interest rates, changes in market conditions and issuer-specific events, 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:

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

Extension risk: When interest rates are rising, the average life of securities backed by callable debt obligations may be extended because of slower than expected principal payments. This would lock in a below-market interest rate, increase the security's duration and reduce the value of the security.

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. Securities with longer durations tend to be more sensitive to changes in interest rates and are usually more volatile than securities with shorter durations. For example, a 5 year average duration generally means the price of a fixed income security will decrease in value by 5% if interest rates rise by 1%. Interest rates in the U.S. are near historic lows, which may increase the Fund's exposure to risks associated with rising rates. 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 securities when the Subadviser may wish to sell or must sell to meet redemptions.

Liquidity risk: A particular investment may be difficult to purchase or sell and the Fund may be unable to sell illiquid securities at an advantageous time or price or achieve its desired level of exposure to a certain sector. Liquidity risk may result from the lack of an active market, reduced number and capacity of traditional market participants to make a market in fixed income securities, and may be magnified in a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, causing increased supply in the market due to selling activity. Valuation of investments may be difficult, particularly during periods of market volatility or reduced liquidity and for investments that trade infrequently or irregularly. In these circumstances, among others, an investment may be valued using fair value methodologies that are inherently subjective and reflect good faith judgments based on available information.

Market and issuer risk: Securities markets are volatile and can decline significantly in response to adverse market, economic, political, regulatory or other 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.

Mortgage- and asset-backed securities risk: Mortgage and other asset-backed derivatives in the Fund's portfolio may have especially volatile prices because the embedded leverage can magnify the impact of the extension or contraction event on the underlying cash flow. Mortgage-related securities are also subject to prepayment and extension risks.

Prepayment risk: When interest rates are declining, the issuer of a fixed income security, including a pass-through security such as a mortgage-backed or an asset-backed security, may exercise its option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding securities.

Selection risk: The Subadviser's judgment about the attractiveness, value and growth potential of a particular security may be incorrect. The Subadviser potentially will be prevented from executing investment decisions at an advantageous time or price as a result of any domestic or global market disruptions, particularly disruptions causing heightened market volatility and reduced market liquidity, as well as increased or changing regulations. Thus, investments that the Subadviser believes represent an attractive opportunity or in which the Fund seeks to obtain exposure may be unavailable entirely or in the specific quantities or prices sought by the Subadviser and the Fund may need to obtain the exposure through less advantageous or indirect investments or forgo the investment at the time.

U.S. government securities risk: Securities issued or guaranteed by U.S. government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. government. As a result, no assurance can be given that the U.S. government will provide financial support to these securities or issuers (such as securities issued by the Federal National Mortgage Association, or the Federal Home Loan Mortgage Corporation). Although certain government securities are backed by the full faith and credit of the U.S. government (such as securities issued by the Government National Mortgage Association), circumstances could arise that would delay or prevent the payment of interest or principal. It is possible that issuers of U.S. government securities will not have the funds to meet their payment obligations in the future and, in these circumstances, the Fund's returns may be adversely affected.
