SAI PRIMER

The SAI is a part of the Funds’ registration statement that is filed with the SEC. The registration statement includes the Funds’ prospectuses, the SAI and certain exhibits. The SAI, as supplemented from time to time, can be found online at columbiathreadneedleus.com and/or by accessing the SEC’s website at www.sec.gov.

For purposes of any electronic version of this SAI, all references to websites or universal resource locators (URLs) are intended to be inactive and are not meant to incorporate the contents of any such website or URL into this SAI, with the exception of the most recent annual report for each Fund, as noted on the front cover of this SAI.

The SAI generally provides additional information about the Funds that is not required to be in the Funds’ prospectuses. The SAI expands discussions of certain matters described in the Funds’ prospectuses and provides certain additional information about the Funds that may be of help or interest to some investors. Among other things, the SAI provides information about:

■	the organization of each Trust (of which the Funds are series);
■	the Funds’ investments;
■	the Funds’ investment adviser, investment subadviser(s) (if any) and other service providers, including roles and relationships of Ameriprise Financial and its affiliates, and conflicts of interest;
■	the governance of the Funds;
■	the Funds’ brokerage practices;
■	the share classes offered by the Funds;
■	the purchase, redemption and pricing of Fund shares; and
■	the application of U.S. federal income tax laws.

If you have any questions about the Funds, please call Columbia Funds at 800.345.6611 or contact your financial advisor.

Throughout this SAI, the term “financial intermediary” may refer, generally, to one or more of the selling agents and/or servicing agents that are authorized to sell and/or service shares of the Funds, which may include broker-dealers and financial advisors as well as firms that employ such broker-dealers and financial advisors, including, for example, brokerage firms, banks, investment advisers, third party administrators and other financial intermediaries.

Each Fund typically updates its registration statement approximately four months after the end of its fiscal year, although in certain circumstances a Fund may update its registration statement sooner. Some of the information in this SAI is reported for a Fund as of the end of the Fund’s last fiscal year (or period) or during the Fund’s last fiscal year (or period). This is a reference to the fiscal year (or period) ending prior to the Fund’s last annual update, which may be fifteen months or more prior to the date of the SAI. See About the Trusts for each Fund’s fiscal year end and most recent prospectus date (i.e., the date of the Fund’s last annual update).

Before reading the SAI, you should consult the prospectus for the Fund as well as the Glossary below, which defines certain of the terms used in the SAI. Terms not defined in the Glossary below generally have the same meaning as otherwise ascribed in a Fund’s prospectus.

Business Day	Any day on which the NYSE is open for business. A business day typically ends at the close of regular trading on the NYSE, usually at 4:00 p.m. Eastern time. If the NYSE is scheduled to close early, the business day will be considered to end as of the time of the NYSE’s scheduled close. The Fund will not treat an intraday unscheduled disruption in NYSE trading or an intraday unscheduled closing as a close of regular trading on the NYSE for these purposes and will price its shares as of the regularly scheduled closing time for that day (typically, 4:00 p.m. Eastern time). Notwithstanding the foregoing, the NAV of Fund shares may be determined at such other time or times (in addition to or in lieu of the time set forth above) as the Fund’s Board may approve or ratify. On holidays and other days when the NYSE is closed, the Fund's NAV is not calculated and the Fund does not accept buy or sell orders. However, the value of the Fund's assets may still be affected on such days to the extent that the Fund holds foreign securities that trade on days that foreign securities markets are open.

*	Certain Funds reorganized into series of a Trust. The date of operations for these Funds represents the date on which the predecessor funds began operations.

**

A “diversified” Fund may not, with respect to 75% of its total assets, invest more than 5% of its total assets in securities of any one issuer or purchase more than 10% of the outstanding voting securities of any one issuer, except obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities and except securities of other investment companies. A “non-diversified” Fund may invest a greater percentage of its total assets in the securities of fewer issuers than a “diversified” fund, which increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a “diversified” fund holding a greater number of investments. Accordingly, a “non-diversified” Fund’s value will likely be more volatile than the value of a more diversified fund.

***	The Fund Investment Category is used as a convenient way to describe Funds in this SAI and should not be deemed a description of the Fund’s principal investment strategies, which are described in the Fund’s prospectus.

FUNDAMENTAL AND NON-FUNDAMENTAL INVESTMENT POLICIES

The following discussion of “fundamental” and “non-fundamental” investment policies and limitations for each Fund supplements the discussion of investment policies in the Funds’ prospectuses. A fundamental policy may be changed only with Board and shareholder approval. A non-fundamental policy may be changed only with Board approval and does not require shareholder approval.

Unless otherwise noted in a Fund’s prospectus or this SAI, whenever an investment policy or limitation states a maximum percentage of a Fund’s assets that may be invested in any security or other asset, or sets forth a policy regarding an investment standard, compliance with such percentage limitation or standard will be determined solely at the time of the Fund’s acquisition of such security or asset (Time of Purchase Standard). Thus, a Fund may continue to hold a security, even though it causes the Fund to exceed a percentage limitation or not meet a standard, because of post-acquisition changes, including fluctuation in the value of the Fund’s assets.

In adhering to the fundamental and non-fundamental investment restrictions and policies applicable to each of Commodity Strategy Fund, MM Alternative Strategies Fund and Multi Strategy Alternatives Fund, each such Fund will, to the extent possible, treat any assets of its Subsidiary generally as if the assets were held directly by the Fund.

Notwithstanding the policies set forth in this SAI for Government Money Market Fund, the Fund will comply with the applicable provisions of Rule 2a-7 under the 1940 Act (Rule 2a-7).

Fundamental Policies

The table below shows Fund-specific policies that may be changed only with a “vote of a majority of the outstanding voting securities” of the Fund, which means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of the Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The table indicates whether or not a fund has a policy on a particular topic. A dash indicates that the Fund does not have a Fundamental policy on a particular topic. The specific policy is stated in the paragraphs that follow the table.
