Bridges Investment Fund, Inc.

Bridges Investment Fund, Inc.

Investment Objective:

Bridges Investment Fund, Inc. (the “Fund”) seeks long-term capital appreciation,

with a secondary objective of generating a modest amount of current income.

Fees and Expenses of the Fund :

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	Bridges Investment Fund, Inc. Bridges Investment Fund, Inc.
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	none
Maximum Deferred Sales Charge (Load) on Reinvested Dividends and other Distributions	none
Redemption Fee (as a percentage of amount redeemed)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	Bridges Investment Fund, Inc. Bridges Investment Fund, Inc.
Management Fees	0.50%
Distribution (12b-1) Fees	none
Other Expenses	0.30%
Acquired Fund Fees and Expenses	0.02%	[1]
Total Annual Fund Operating Expenses	0.82%	[1]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of these periods.  The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
Bridges Investment Fund, Inc. | Bridges Investment Fund, Inc. | USD ($)	84	262	455	1,014

Portfolio Turnover :

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio).  A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account.  These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance.  During the most recent fiscal year, the Fund’s portfolio turnover rate was 13.23% of the average value of its portfolio.

Principal Investment Strategies of the Fund :

The Fund seeks to achieve its investment objectives by investing primarily in a diversified portfolio of common stocks, which Fund management believes offers the potential for increased earnings and dividends over time.  Normally, such equity securities will represent 60% or more of the Fund’s net assets.  However, the overall asset allocation is set by Fund management’s determination of the most attractive risk adjusted return opportunities available in both equity and fixed income securities.

The equity investment approach of Bridges Investment Management, Inc. ( “BIM ” or the “Adviser”) emphasizes owning companies in the Fund which it believes offer the best potential for above-average, long-term capital appreciation.  The Adviser’s equity investment process focuses on identifying companies which have accelerating revenues, earnings growth, strong dividend growth potential, free cash flow growth, expanding margins and strong balance sheets.  Market capitalization or company size is a result of this investment approach rather than an active investment consideration.  Historically, the Fund has primarily owned securities in larger companies, although at any time, the Fund may own securities in small, medium, or large size companies.  The Fund may also invest in common stocks which the Adviser believes may be cyclically depressed or undervalued, and therefore, may offer potential for capital appreciation.

In pursuing these principal investment objectives, the Fund may invest up to 15% of its total assets in U.S. dollar-denominated securities of foreign issuers traded on U.S. exchanges, and up to 20% of its total assets in American Depositary Receipts (“ADRs”) traded on U.S. exchanges or in the U.S. over-the-counter market.

In addition, to generate current income, as part of its principal strategy, the Fund may acquire investment grade corporate bonds, debentures, U.S. Treasury bonds and notes, and preferred stocks.  Historically, such fixed income securities have not constituted more than 40% of the market value of the Fund’s portfolio.  Two considerations drive the Adviser’s maturity strategy with respect to fixed income securities.  First, the Adviser will generally manage the weighted average life of the Fund’s fixed income portfolio given its perception of where value lies at any point in time on the yield curve.  Second, the Adviser will manage the weighted average life of the Fund’s fixed income portfolio based on its intermediate to longer-term outlook for interest rates at any point in time.

The allocation of Fund investments among common stocks and other equity securities and bonds and other debt securities (including U.S. Treasury securities) is based on the Adviser’s judgments about the potential returns and risks of each class.  The Adviser considers a number of factors when making these allocations, including economic conditions and monetary factors, inflation and interest levels and trends, and fundamental factors (such as price/earnings ratios or growth rates) of individual companies in which the Fund invests.

Principal Risks of Investing in the Fund :

The risks associated with an investment in the Fund can increase during times of significant market volatility.  There is the risk that you could lose all or a portion of your investment in the Fund.  The following risks could affect the value of your investment:

Market Risk: The prices of the stocks in which the Fund invests may decline for a number of reasons such as changing economic, political or market conditions.  The price declines may be steep, sudden and/or prolonged.

Interest Rate Risk: The market value of bonds and other debt securities generally declines when interest rates rise.  This risk is greater for bonds with longer maturities.
Credit Risk: The risk of investments in bonds and debt securities whose issuers may not be able to make interest and principal payments.  In turn, issuers’ inability to make payments may lower the credit quality of the security and lead to greater volatility in the price of the security.

Asset Allocation Risk: The risk that asset allocation to a particular strategy does not reflect actual market movement or the effect of economic conditions.  The Fund’s performance may be affected by the Adviser’s ability to anticipate correctly the relative potential returns and risks of the types of assets in which the Fund invests.

Small and Medium Capitalization Risk:  Investing in securities of small and medium capitalization companies may involve greater volatility than investing in larger and more established companies because small and medium capitalization companies can be subject to more abrupt or erratic share price changes than larger, more established companies.

Foreign Securities and ADR Risk: Investing in foreign issuer securities and ADRs may involve risks in addition to the risks in domestic investments, including less regulatory oversight and less publicly-available information, less stable governments and economies, and non-uniform accounting, auditing and financial reporting standards.

Performance:

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and how the Fund’s average annual returns over time compare with those of a broad measure of market performance, as well as indices that reflect the market sectors in which the Fund invests.  The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Total Return for the Calendar Years Ended December 31

The Fund’s highest and lowest returns for a calendar quarter during the 10 year period shown on the bar chart are a return of 17.28% for the quarter ended June 30, 2009, and -23.33% for the quarter ended December 31, 2008.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). The Fund’s return after taxes on distributions and sale of fund shares is higher than its return before taxes and after taxes on distributions because it includes a tax benefit resulting from the capital losses that would have been incurred, and could be utilized against other capital gains an investor may have.

[1] Acquired Fund Fees and Expenses are indirect fees and expenses that funds incur from investing in the shares of other mutual funds. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table may differ from the Ratio of Net Expenses to Average Net Assets included in the "Financial Highlights" section of the statutory prospectus which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.
