Please see the Fund’s prospectus in the Literature section of the page for a description of risks associated with the Fund.

Performance data shown represents past performance and is not a guarantee of future results. The investment return and principal value of an investment will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data shown. Returns shown assume reinvestment of distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.

Performance for different share classes varies based on differences in sales charges and fees associated with each class. Not all Funds offer every class of shares.

Net asset value (NAV) returns do not include sales charges or contingent deferred sales charges (CDSC). If they were included, returns would be lower.

Class A: Public offering price (POP) returns are calculated with the effect of the maximum initial sales charge.

Class B: Class B shares are closed to new investors. Returns W/CDSC are calculated with the effect of a contingent deferred sales charge (CDSC).

Class C: Returns W/CDSC are calculated with the effect of a CDSC.

Class T: POP returns are calculated with the effect of the maximum initial sales charge.

Class R, R4, R5, Y and Z: Shares are sold only at NAV. Only eligible investors may purchase these shares. See the prospectus for eligibility requirements and other important information.

Gross expense ratio: Fund expense ratios are calculated based on the Fund’s average net assets during the Fund’s most recently completed fiscal year (or based on estimated amounts for funds that have been in existence less than one year), and have not been adjusted for current asset levels. If adjusted for any decrease or increase in assets, expense ratios would be higher or lower, respectively, than the numbers shown above. Please see the Fund’s prospectus for additional details. The net and gross expense ratios shown are updated on the first day of each month.

Net expense ratio: Net expenses are after expense waiver/reimbursement. The investment manager and certain of its affiliates have contractually (for at least the current fiscal year) and/or voluntarily agreed to waive certain fees and/or to reimburse certain expenses of the Fund, as described in the Fund’s prospectus, unless sooner terminated at the sole discretion of the Fund’s board. Fee waivers/expense caps would limit the impact that any decrease in assets would have on net expense ratios in the current fiscal year. Voluntary waivers/reimbursement arrangements, if any, may be discontinued at any time. The net and gross expense ratios shown are updated on the first day of each month.

*Inception date shown is the share class inception date. The since inception returns shown are since fund inception. Returns shown for periods prior to the fund’s share class inception date include the returns of the oldest share class of the fund, adjusted to reflect higher class-related operating expenses, as applicable. In addition, the returns shown include the returns of any predecessor to the fund. Click here for more information.

Morningstar Rating

The Overall Morningstar Rating for a retail mutual fund is derived from a weighted average of the performance figures associated with its 3-, 5- and 10-year (if applicable) Morningstar Rating metrics. For share classes that do not have a 3-, 5-, or 10-year actual performance history, the fund’s independent Morningstar Rating metric is then compared against the retail mutual fund universe breakpoints to determine its hypothetical rating. Past performance does not guarantee future results.

Extended performance is the process of lengthening the available data for a younger investment based on a related older share class or former investment structure. Morningstar provides extended performance for rankings for eligible open-end mutual funds when the share class does not have a 3-, 5-, or 10-year actual performance history. Some of the rankings shown on this website are for newer share classes and are calculated using extended performance. Please note, some of the Morningstar proprietary calculations, including the Morningstar Rating TM. are not customarily calculated based on adjusted historical returns. The evaluation of this investment does not affect the retail mutual fund data published by Morningstar. For each retail mutual fund with at least a 3-year history, Morningstar calculates a Morningstar Rating based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) The Morningstar Ratings are for the classes shown only; other classes may have different performance characteristics and may have different ratings.

Morningstar Percentile Rankings are based on the average annual total returns of the funds in the category for the periods stated and do not include any sales charges or redemption fees, but do not include 12b-1 fees and the reinvestment of dividends and capital gains distributions.  The highest (or most favorable) percentile rank is 1 and the lowest (or least favorable) percentile rank is 100.  Rankings for each share class will vary due to different expenses.  Had sales charges or redemption fees been included, total returns would be lower.

Morningstar Style Box

The Morningstar Style Box TM is based on the Fund’s portfolio holdings as of period end. The vertical axis shows the market capitalization of the stocks owned, and the horizontal axis shows investment style (value, blend, or growth). Information shown is based on the most recent data provided by Morningstar. The Morningstar style box data is updated on the 10th business day after every month end.

Alpha measures the relationship between the Fund’s performance and its beta over a three-year period. Alpha greater than 0.0 means an investment has performed better than the compared index given its level of risk. It can be viewed as a measure of the value added by the Fund manager.

Average effective duration provides a measure of the fund’s interest-rate sensitivity.

Beta measures a fund’s risk relative to its benchmark The index is equivalent to 1.0. A fund with a beta greater than 1.0 has been more volatile than the index while a fund with a beta less than 1.0 has been less volatile.

Price-to-Book Ratio is a stock’s price divided by its book value, and may help determine if the stock is valued fairly.

Price-to-Earnings Ratio is a stock’s price divided by after-tax earnings over a trailing 12-month period, which serves as an indicator of value based on earnings.

R-Squared ranges from 0.00 to 100 and measures how closely the Fund’s performance matches (or doesn’t match) the performance of its benchmark index.

30-day SEC Yield. The SEC yield should be regarded as an estimate of the fund’s rate of investment income reflecting an estimated yield to maturity (assuming all current portfolio holdings are held to maturity), and it may not equal the fund’s actual income distribution rate or the income paid to a shareholder’s account. The yield shown reflects fee waivers in effect, if any. In the absence of such waivers, yields would be reduced. The fund may own treasury inflation protected securities (TIPS) or other inflation indexed securities. If so, the yield will reflect an inflation adjustment that is attributable to these securities. This adjustment and the resulting yield can be positive (in the case of inflation) or negative (in the case of deflation) during the period shown.

Unsubsidized 30-day SEC Yield: The unsubsidized yield shown is the SEC yield adjusted to reflect the gross expense ratio applicable to the class of shares shown and without regard to the contractual reimbursements and fee waivers required of the fund’s investment manager and affiliates.

The 30-day yields may appear to be the same due to rounding.

The Columbia Inflation Protection Securities Fund and certain other funds own treasury inflation protected securities (TIPS) or other inflation indexed securities. For a fund that owns TIPS or other inflation indexed securities, the SEC Yield, when shown, will reflect an inflation adjustment that is attributable to these types of securities. This adjustment as well as the resulting yield can be positive (in the case of inflation) or negative (in the case of deflation) during the period shown. Absent the inflation adjustment, the yield shown may be materially different and may vary significantly from month to month, especially for a fund such as Columbia Inflation Protection Securities Fund which invests substantially in TIPS and other inflation indexed securities. In periods when the SEC yield is exceptionally high due to a rise in the inflation rate, it is important to bear in mind that the adjustment in the yield from the inflation rate may not be repeated.

Sharpe Ratio divides a fund’s return in excess of the 90-day Treasury bill by the investment’s standard deviation to measure risk-adjusted performance.

Standard Deviation is a statistical measure of the degree to which an individual value in a probability distribution tends to vary from the mean of the distribution.

Turnover Rate (fiscal year end%) measures the percentage of holdings that has been turned over or replaced, in the past year.

Average Coupon is a calculation of the total interest cost for a bond issue expressed as a percentage. The average coupon is equal to the total interest payments of an issue divided by bond year dollars.

Duration to Worst is the duration of a bond computed using the bond’s nearest call date or maturity, whichever comes first. This measure ignores future cash flow fluctuations due to embedded optionality.
