Fair value measurements

The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

■	Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.

■	Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

■	Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.

Certain investments that have been measured at fair value using the net asset value (NAV) per share (or its equivalent) are not categorized in the fair value hierarchy. The fair value amounts presented in the table are intended to reconcile the fair value hierarchy to the amounts presented in the Portfolio of Investments. The Columbia Short-Term Cash Fund seeks to provide shareholders with maximum current income consistent with liquidity and stability of principal. Columbia Short-Term Cash Fund prices its shares with a floating NAV and no longer seeks to maintain a stable NAV.

Fair value measurements (continued)
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.

Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

The following table is a summary of the inputs used to value the Fund’s investments at January 31, 2019:

Fair value measurements (continued)
There were no transfers of financial assets between Levels 1 and 2 during the period.

Financial assets were transferred from Level 3 to Level 2 as observable market inputs were utilized and management determined that there was sufficient, reliable and observable market data to value these assets as of period end.

Transfers between levels are determined based on the fair value at the beginning of the period for security positions held throughout the period.

The following table is a reconciliation of Level 3 assets for which significant observable and unobservable inputs were used to determine fair value:

	Balance as of 04/30/2018 ($)	Increase (decrease) in accrued discounts/ premiums ($)	Realized gain (loss) ($)	Change in unrealized appreciation (depreciation)^(a) ($)	Purchases ($)	Sales ($)	Transfers into Level 3 ($)	Transfers out of Level 3 ($)	Balance as of 01/31/2019 ($)

Total	6,591,772	200	-	8,638	2,953,467	(545)	-	(6,590,022)	2,963,510

(a) Change in unrealized appreciation (depreciation) relating to securities held at January 31, 2019 was $8,638, which is comprised of Asset-Backed Securities — Non-Agency of $(252) and Residential Mortgage-Backed Securities — Non-Agency of $8,890.

The Fund’s assets assigned to the Level 3 category are valued utilizing the valuation technique deemed the most appropriate in the circumstances. Certain residential mortgage backed and asset backed securities classified as Level 3 securities are valued using the market approach and utilize single market quotations from broker dealers which may have included, but not limited to, the distressed nature of the security and observable transactions for similar assets in the market. Significant increases (decreases) to any of these inputs would result in a significantly higher (lower) fair value measurement.

Fair value measurements

2	Columbia U.S. Treasury Index Fund \| Quarterly Report 2019

Portfolio of Investments (continued)
Columbia U.S. Treasury Index Fund, January 31, 2019 (Unaudited)

Fair value measurements (continued)
pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

■	Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.

■	Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

■	Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.

The following table is a summary of the inputs used to value the Fund’s investments at January 31, 2019:

	Level 1 quoted prices in active markets for identical assets ($)	Level 2 other significant observable inputs ($)	Level 3 significant unobservable inputs ($)	Investments measured at net asset value ($)	Total ($)

(b)	Represents fair value as determined in good faith under procedures approved by the Board of Trustees. At January 31, 2019, the total value of these securities amounted to $9,525, which represents less than 0.01% of total net assets.
(c)	Negligible market value.

Notes to Portfolio of Investments (continued)

(e)	Represents privately placed and other securities and instruments exempt from SEC registration (collectively, private placements), such as Section 4(a)(2) and Rule 144A eligible securities, which are often sold only to qualified institutional buyers. The Fund may invest in private placements determined to be liquid as well as those determined to be illiquid. Private placements may be determined to be liquid under guidelines established by the Fund’s Board of Trustees. At January 31, 2019, the total value of these securities amounted to $172,136,577, which represents 15.61% of total net assets.
(f)	Represents a security purchased on a when-issued basis.
(g)	Represents a variable rate security with a step coupon where the rate adjusts according to a schedule for a series of periods, typically lower for an initial period and then increasing to a higher coupon rate thereafter. The interest rate shown was the current rate as of January 31, 2019.
(h)	Represents securities that have defaulted on payment of interest. The Fund has stopped accruing interest on these securities. At January 31, 2019, the total value of these securities amounted to $9,525, which represents less than 0.01% of total net assets.
(i)	Principal and interest may not be guaranteed by the government.
(j)	The stated interest rate represents the weighted average interest rate at January 31, 2019 of contracts within the senior loan facility. Interest rates on contracts are primarily determined either weekly, monthly or quarterly by reference to the indicated base lending rate and spread and the reset period. These base lending rates are primarily the London Interbank Offered Rate (“LIBOR”) and other short-term rates. Base lending rates may be subject to a floor or minimum rate. The interest rate for senior loans purchased on a when-issued or delayed delivery basis will be determined upon settlement, therefore no interest rate is disclosed. Senior loans often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, cannot be predicted with accuracy. As a result, remaining maturities of senior loans may be less than the stated maturities.
(k)	Variable rate security. The interest rate shown was the current rate as of January 31, 2019.
(l)	Represents a security purchased on a forward commitment basis.
(m)	The rate shown is the seven-day current annualized yield at January 31, 2019.
(n)	As defined in the Investment Company Act of 1940, an affiliated company is one in which the Fund owns 5% or more of the company’s outstanding voting securities, or a company which is under common ownership or control with the Fund. Holdings and transactions in these affiliated companies during the period ended January 31, 2019 are as follows:

Issuer	Beginning shares	Shares purchased	Shares sold	Ending shares	Realized gain (loss) — affiliated issuers ($)	Net change in unrealized appreciation (depreciation) — affiliated issuers ($)	Dividends — affiliated issuers ($)	Value — affiliated issuers at end of period ($)

Investments are valued using policies described in the Notes to Financial Statements in the most recent shareholder report.

Fair value measurements

Fair value inputs are summarized in the three broad levels listed below:

■	Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.

■	Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

■	Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Fair value measurements (continued)
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.

The following table is a summary of the inputs used to value the Fund’s investments at January 31, 2019:

	Level 1 quoted prices in active markets for identical assets ($)	Level 2 other significant observable inputs ($)	Level 3 significant unobservable inputs ($)	Investments measured at net asset value ($)	Total ($)

The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets. These assets include certain foreign securities for which a third party statistical pricing service may be employed for purposes of fair market valuation. The model utilized by such third party statistical pricing service takes into account a security’s correlation to available market data including, but not limited to, intraday index, ADR, and exchange-traded fund movements.

Derivative instruments are valued at unrealized appreciation (depreciation).

There were no transfers of financial assets between levels during the period.

Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate or sovereign issues as of period end serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

Private placements may be determined to be liquid under guidelines established by the Fund’s Board of Trustees. At January 31, 2019, the total value of these securities amounted to $1,120,679,567, which represents 57.72% of total net assets.
(b)	Variable rate security. The interest rate shown was the current rate as of January 31, 2019.
(c)	Represents fair value as determined in good faith under procedures approved by the Board of Trustees. At January 31, 2019, the total value of these securities amounted to $21,887,444, which represents 1.13% of total net assets.
(d)	Valuation based on significant unobservable inputs.
(e)	Represents a security purchased on a when-issued basis.
(f)	Represents shares owned in the residual interest of an asset-backed securitization.
(g)	Zero coupon bond.

(i)	Non-income producing investment.
(j)	Negligible market value.
(k)	Represents a variable rate security with a step coupon where the rate adjusts according to a schedule for a series of periods, typically lower for an initial period and then increasing to a higher coupon rate thereafter. The interest rate shown was the current rate as of January 31, 2019.
(l)	Represents securities that have defaulted on payment of interest. The Fund has stopped accruing interest on these securities. At January 31, 2019, the total value of these securities amounted to $41,069, which represents less than 0.01% of total net assets.
(m)	Principal and interest may not be guaranteed by the government.
(n)	Represents interest only securities which have the right to receive the monthly interest payments on an underlying pool of mortgage loans.
(o)	This security or a portion of this security has been pledged as collateral in connection with derivative contracts.
(p)	The stated interest rate represents the weighted average interest rate at January 31, 2019 of contracts within the senior loan facility. Interest rates on contracts are primarily determined either weekly, monthly or quarterly by reference to the indicated base lending rate and spread and the reset period. These base lending rates are primarily the London Interbank Offered Rate (“LIBOR”) and other short-term rates. Base lending rates may be subject to a floor or minimum rate. The interest rate for senior loans purchased on a when-issued or delayed delivery basis will be determined upon settlement, therefore no interest rate is disclosed. Senior loans often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, cannot be predicted with accuracy. As a result, remaining maturities of senior loans may be less than the stated maturities.
(q)	Represents a security purchased on a forward commitment basis.
(r)	The rate shown is the seven-day current annualized yield at January 31, 2019.
(s)	As defined in the Investment Company Act of 1940, an affiliated company is one in which the Fund owns 5% or more of the company’s outstanding voting securities, or a company which is under common ownership or control with the Fund. Holdings and transactions in these affiliated companies during the period ended January 31, 2019 are as follows:

Issuer	Beginning shares	Shares purchased	Shares sold	Ending shares	Realized gain (loss) — affiliated issuers ($)	Net change in unrealized appreciation (depreciation) — affiliated issuers ($)	Dividends — affiliated issuers ($)	Value — affiliated issuers at end of period ($)

Fair value measurements

Fair value inputs are summarized in the three broad levels listed below:

■	Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.

■	Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

■	Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Futures contracts and swap contracts are valued at unrealized appreciation (depreciation).

There were no transfers of financial assets between Levels 1 and 2 during the period.

Transfers between levels are determined based on the fair value at the beginning of the period for security positions held throughout the period.

The following table is a reconciliation of Level 3 assets for which significant observable and unobservable inputs were used to determine fair value:

	Balance as of 04/30/2018 ($)	Increase (decrease) in accrued discounts/ premiums ($)	Realized gain (loss) ($)	Change in unrealized appreciation (depreciation)^(a) ($)	Purchases ($)	Sales ($)	Transfers into Level 3 ($)	Transfers out of Level 3 ($)	Balance as of 01/31/2019 ($)

(a) Change in unrealized appreciation (depreciation) relating to securities held at January 31, 2019 was $(918,968), which is comprised of Asset-Backed Securities — Non-Agency of $(957,704) and Residential Mortgage-Backed Securities — Non-Agency of $38,736.

The Fund’s assets assigned to the Level 3 category are valued utilizing the valuation technique deemed the most appropriate in the circumstances.

Certain corporate bonds and common stock classified as Level 3 are valued using a market approach. To determine fair value for these securities, management considered various factors which may have included, but were not limited to, trades of similar securities, estimated earnings of the respective company, market multiples derived from a set of comparable companies, and the position of the security within the respective company’s capital structure. Significant increases (decreases) to any of these inputs would result in a significantly higher (lower) fair value measurement. Generally, a change in estimated earnings of the respective company might result in change to the comparable companies and market multiples.

Certain residential and asset backed securities classified as Level 3 securities are valued using the market approach and utilize single market quotations from broker dealers which may have included, but were not limited to, observable transactions for identical or similar assets in the market and the distressed nature of the security. The appropriateness of fair values for these securities is monitored on an ongoing basis which may include results of back testing, manual price reviews and other control procedures. Significant increases (decreases) to any of these inputs would result in a significantly higher (lower) fair value measurement.

Notes to Portfolio of Investments

(a)	Represents privately placed and other securities and instruments exempt from SEC registration (collectively, private placements), such as Section 4(a)(2) and Rule 144A eligible securities, which are often sold only to qualified institutional buyers. The Fund may invest in private placements determined to be liquid as well as those determined to be illiquid. Private placements may be determined to be liquid under guidelines established by the Fund’s Board of Trustees. At January 31, 2019, the total value of these securities amounted to $67,971,751, which represents 49.25% of total net assets.
(b)	Variable rate security. The interest rate shown was the current rate as of January 31, 2019.
(c)	Variable or floating rate security, the interest rate of which adjusts periodically based on changes in current interest rates and prepayments on the underlying pool of assets. The interest rate shown was the current rate as of January 31, 2019.
(d)	Non-income producing investment.
(e)	Represents a security purchased on a when-issued basis.
(f)	Represents a variable rate security with a step coupon where the rate adjusts according to a schedule for a series of periods, typically lower for an initial period and then increasing to a higher coupon rate thereafter. The interest rate shown was the current rate as of January 31, 2019.
(g)	By investing in the equity-linked note, the Fund gains exposure to the underlying investments that make up the custom basket without having to own the underlying investments directly. The components of the basket are available on the Columbia Multi-Asset Income Fund’s page of columbiathreadneedleus.com website.
(h)	Principal and interest may not be guaranteed by the government.
(i)	Represents securities that have defaulted on payment of interest. The Fund has stopped accruing interest on these securities. At January 31, 2019, the total value of these securities amounted to $364,628, which represents 0.26% of total net assets.
(j)	Represents interest only securities which have the right to receive the monthly interest payments on an underlying pool of mortgage loans.
(k)	Represents fair value as determined in good faith under procedures approved by the Board of Trustees. At January 31, 2019, the total value of these securities amounted to $298,500, which represents 0.22% of total net assets.
(l)	Valuation based on significant unobservable inputs.
(m)	The stated interest rate represents the weighted average interest rate at January 31, 2019 of contracts within the senior loan facility. Interest rates on contracts are primarily determined either weekly, monthly or quarterly by reference to the indicated base lending rate and spread and the reset period. These base lending rates are primarily the London Interbank Offered Rate (“LIBOR”) and other short-term rates. Base lending rates may be subject to a floor or minimum rate. The interest rate for senior loans purchased on a when-issued or delayed delivery basis will be determined upon settlement, therefore no interest rate is disclosed. Senior loans often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, cannot be predicted with accuracy. As a result, remaining maturities of senior loans may be less than the stated maturities.
(n)	Represents a security purchased on a forward commitment basis.
(o)	The rate shown is the seven-day current annualized yield at January 31, 2019.

Investments are valued using policies described in the Notes to Financial Statements in the most recent shareholder report.

Fair value measurements

Fair value inputs are summarized in the three broad levels listed below:

■	Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.

■	Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

■	Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

The following table is a summary of the inputs used to value the Fund’s investments at January 31, 2019:

Fair value measurements (continued)
The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets.

Derivative instruments are valued at unrealized appreciation (depreciation).

Financial assets were transferred from Level 1 to Level 2 as the market for these assets was deemed not to be active and fair values were consequently obtained using observable market inputs rather than quoted prices for identical assets as of period end.

Transfers between levels are determined based on the fair value at the beginning of the period for security positions held throughout the period.

The following table(s) show(s) transfers between levels of the fair value hierarchy:

Transfers In		Transfers Out
Level 1 ($)	Level 2 ($)	Level 1 ($)	Level 2 ($)
—	162,086	162,086	—

Transfers In		Transfers Out
Level 2 ($)	Level 3 ($)	Level 2 ($)	Level 3 ($)
506,790	—	—	506,790

The Fund does not hold any significant investments (greater than one percent of net assets) categorized as Level 3.

The Fund’s assets assigned to the Level 3 category are valued utilizing the valuation technique deemed the most appropriate in the circumstances. Certain residential mortgage backed securities classified as Level 3 securities are valued using the market approach and utilize single market quotations from broker dealers which may have included, but were not limited to, observable transactions for identical or similar assets in the market and the distressed nature of the security. The appropriateness of fair values for these securities is monitored on an ongoing basis which may include results of back testing, manual price reviews and other control procedures. Significant increases (decreases) to any of these inputs would result in a significantly higher (lower) valuation measurement.
