The 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 also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example includes contractual commitments to waive fees and reimburse expenses expiring as indicated in the preceding table. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 year		3 years		5 years		10 years
Class A (whether or not shares are redeemed)	$	384	$	605	$	844	$	1,531

The “Past Performance” section is hereby replaced with the following:

For Class A, Class B, Class C, Class I, Class R, Class R4 and Class W prospectus

PAST PERFORMANCE

The following bar chart and table show you how the Fund has performed in the past, and can help you understand the risks of investing in the Fund. The bar chart shows how the Fund's Class A share performance (without sales charges) has varied for each full calendar year shown. If the sales charge was reflected, returns shown would be lower. The table below the bar chart compares the Fund's returns (after applicable sales charges) for the periods shown with those of its benchmark indices. The inception date of the Fund's Class A, Class B, Class C, Class I and Class R4 shares is March 4, 2004, the inception date of the Fund's Class W shares is December 1, 2006 and the inception date of the Fund's Class R shares is August 3, 2009. The returns shown for each of these classes of shares include the returns of the Fund's Class A shares (adjusted to reflect higher class-related operating expenses of such classes, where applicable) for periods prior to the relevant class inception date. Except for differences in expenses and sales charges (where applicable), the share classes of the Fund have annual returns substantially similar because all share classes invest in the same portfolio of securities.

The Fund's past performance (before and after taxes) is no guarantee of how the Fund will perform in the future. Updated performance information can be obtained by calling toll-free 800.345.6611 or visiting columbiamanagement.com.

After-tax returns are shown only for Class A shares. After-tax returns for the other classes will vary. The after-tax returns shown in the table are calculated using the highest historical individual U.S. federal marginal income tax rate and do not reflect the impact of state, local or foreign taxes. Your actual after-tax returns will depend on your personal tax situation and may differ from those shown in the table. In addition, the after-tax returns shown in the table do not apply to shares held in tax-deferred accounts such as 401(k) plans or individual retirement accounts (IRAs).

During the periods shown:

● Highest return for a calendar quarter was 5.14% (quarter ended March 31, 2008).

● Lowest return for a calendar quarter was –3.42% (quarter ended September 30, 2008).

Under this agreement, the Fund's net operating expenses will not, subject to applicable exclusions, exceed the annual rates of 0.85% for Class A, 1.60% for Class B, 1.60% for Class C, 0.42% for Class I, 1.10% for Class R, 0.72% for Class R4, 0.85% for Class W and 0.60% for Class Z.

The Example in the section entitled “Fees and Expenses of the Fund” is hereby replaced with the following:

Example

The 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 your shares at the end of those periods (unless otherwise noted). The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example includes contractual commitments to waive fees and reimburse expenses expiring as indicated in the preceding table. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The “Past Performance” section is hereby replaced with the following:

For Class A, Class B, Class C, Class I, Class R, Class R4 and Class W prospectus

PAST PERFORMANCE

The following bar chart and table show you how the Fund has performed in the past, and can help you understand the risks of investing in the Fund. The bar chart shows how the Fund's Class A share performance (without sales charges) has varied for each full calendar year shown. If the sales charge was reflected, returns shown would be lower. The table below the bar chart compares the Fund's returns (after applicable sales charges) for the periods shown with those of its benchmark indices. The inception date of the Fund's Class A, Class B, Class C, Class I and Class R4 shares is March 4, 2004, the inception date of the Fund's Class W shares is December 1, 2006 and the inception date of the Fund's Class R shares is August 3, 2009. The returns shown for each of these classes of shares include the returns of the Fund's Class A shares (adjusted to reflect higher class-related operating expenses of such classes, where applicable) for periods prior to the relevant class inception date. Except for differences in expenses and sales charges (where applicable), the share classes of the Fund have annual returns substantially similar because all share classes invest in the same portfolio of securities.

The Fund's past performance (before and after taxes) is no guarantee of how the Fund will perform in the future. Updated performance information can be obtained by calling toll-free 800.345.6611 or visiting columbiamanagement.com.

After-tax returns are shown only for Class A shares. After-tax returns for the other classes will vary. The after-tax returns shown in the table are calculated using the highest historical individual U.S. federal marginal income tax rate and do not reflect the impact of state, local or foreign taxes. Your actual after-tax returns will depend on your personal tax situation and may differ from those shown in the table. In addition, the after-tax returns shown in the table do not apply to shares held in tax-deferred accounts such as 401(k) plans or individual retirement accounts (IRAs).

During the periods shown:

● Highest return for a calendar quarter was 5.14% (quarter ended March 31, 2008).

● Lowest return for a calendar quarter was –3.42% (quarter ended September 30, 2008).

● Class A year-to-date return was 4.05% at June 30, 2012.

* On October 1, 2012, the Barclays Inflation-Protected Securities (TIPS) Series-L Index replaced the Barclays U.S. Government Inflation-Linked Bond Index as the Fund’s primary benchmark. This benchmark change was made based on a recommendation by the Fund’s investment manager to the Fund’s Board that the new benchmark provides a more appropriate basis for comparing the Fund’s performance. Information on the new and the old benchmarks shown will be included for a one-year transition period. Thereafter, only the new benchmark will be included.

For Class Z prospectus

PAST PERFORMANCE

The following bar chart and table show you how the Fund has performed in the past, and can help you understand the risks of investing in the Fund. The bar chart shows how the Fund’s Class Z share performance has varied for each full calendar year shown. The table below the bar chart compares the Fund’s Class Z share returns for the periods shown with those of its benchmark indices. The inception date of the Fund’s Class Z shares in September 27, 2010. The returns shown include the returns of the Fund’s Class A shares, which are not offered in this prospectus, for periods prior to Class Z share inception date. Except for differences in expenses and sales charges, Class Z shares have annual returns substantially similar to those of Class A shares because all classes of the Fund’s shares invest in the same portfolio of securities.

The Fund’s past performance (before and after taxes) is no guarantee of how the Fund will perform in the future. Updated performance information can be obtained by calling toll-free 800.345.6611 or visiting columbiamanagement.com.

The after-tax returns shown in the table are calculated using the highest historical U.S. individual federal marginal income tax rate and do not reflect the impact of state, local or foreign taxes. Your actual after-tax returns will depend on your personal tax situation and may differ from those shown in the table. In addition, the after-tax returns shown in the table do not apply to shares held in tax-deferred accounts such as 401(k) plans or individual retirement accounts (IRAs).

During the periods shown:

● Highest return for a calendar quarter was 5.14% (quarter ended March 31, 2008).

● Lowest return for a calendar quarter was –3.42% (quarter ended September 30, 2008).

● Class Z year-to-date return was 4.09% at June 30, 2012.

Information on the new and the old benchmarks shown will be included for a one-year transition period. Thereafter, only the new benchmark will be included.
