Performance data shown represents past performance, which is no guarantee of future results. Current performance may be higher or lower than the performance data shown. Investment returns and the value of an investment will fluctuate, and an investor's shares, when sold, may be worth more or less than their original cost. You can obtain performance data current to the most recent month-end (available within seven business days after the most recent month-end) by calling 800-422-1050 or visiting www.harborfunds.com.

The Harbor Funds performance shown assumes the reinvestment of dividend and capital gain distributions and is net of management fees and expenses. Returns for periods less than one year are not annualized.

From time to time, certain fees and/or expenses have been voluntarily waived, which has resulted in higher returns. Without these waivers, the returns would have been lower. Voluntary waivers may be applied or discontinued at any time without notice.

The MSCI AC (All Country) World Index is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed and emerging markets. This unmanaged index does not reflect fees and expenses and is not available for direct investment.


Contractual expense limitation until 02/29/2012

The Adviser has contractually agreed to limit the Fund's operating expenses through February 29, 2012.  Only the Board of Trustees may modify or terminate this agreement.

Other Expenses and Total Annual Fund Operating Expenses have been restated to reflect current fees.

Ex-Date. The date on which a Fund's net asset value (NAV) will fall by an amount equal to the dividend and/or capital gain distribution plus or minus any change in the value of the Fund's holdings.

About Expense Ratios: All mutual funds have expense ratios which represent what shareholders pay for operating expenses and management fees. Expense ratios are expressed as an annualized percentage of a fund's average net assets paid out in expenses. Net expense ratios reflect adjustments due to voluntary or contractual fee waivers or expense reimbursements. Expense ratio information is as of the Fund's current prospectus, as revised and supplemented from time to time.
