## Management's Discussion of Fund Performance
The performance of the Fund for the period presented is shown in the Average Annual Total Returns table.

### Top Performance Contributors
**Duration** \| Duration and yield curve impacts were positive for the Fund over the period, primarily driven by the excess yield that the Fund was generating relative to the benchmark.

**Agency mortgages** \| An overweight allocation to agency mortgage-backed securities contributed to the Fund's performance, as strong carry, supportive asset class technicals and valuations remained attractive, though spreads tightened through the period resulting in positive Fund performance.

**Consumer-based credit** \| Exposure to consumer-based credit proved beneficial, led by holdings of non-agency mortgage-backed securities as housing fundamentals remained relatively strong and borrower delinquencies remained low. Consumer asset-backed securities delivered strong performance with Fund positions in high-quality securities with relatively stable delinquencies.

### Top Performance Detractors
**Government related debt** \| The Fund's positioning in government-related debt detracted from overall performance, as other asset classes saw stronger excess returns, negatively impacting relative performance.

**Emerging market debt** \| Despite strength across much of the period, emerging market debt detracted from relative performance as a result of heightened geopolitical tensions connected to conflict in the Middle East.

## Management's Discussion of Fund Performance
The performance of the Fund for the period presented is shown in the Average Annual Total Returns table.

### Top Performance Contributors
**Allocation and selection** \| The Fund's performance was positive overall relative to the benchmark for the period. The largest contributor to the Fund's relative performance was from the retail sector, driven primarily by selection and interaction effects within specialty retail. Also notable was allocation to and selection within the energy sector, particularly within gas distribution.

**Credit allocation** \| Allocations to high-quality BB-rated debt and lower-quality B-rated and CCC- rated debt, as well as small allocations to investment-grade debt, were most additive to the Fund's relative performance.

### Top Performance Detractors
**Allocation and selection** \| Despite overall relative positive performance for the Fund, negative returns were driven by industry allocation and selection within the chemicals sector. Also notably offsetting overall positive Fund performance were allocation to and security selection within the oil field equipment and services sector.

**Credit allocation** \| Lower-quality BB-rated debt and higher-quality B-rated debt were most negative for overall Fund returns relative to the benchmark.

## Management's Discussion of Fund Performance
The performance of the Fund for the period presented is shown in the Average Annual Total Returns table.

### Top Performance Contributors
**Allocation and selection** \| The Fund's performance was positive overall relative to the benchmark for the period. The largest contributor to the Fund's relative performance was from the consumer cyclicals sector, particularly driven by selection and allocation effects within specialty retail. Also notable was performance within midstream oil and gas, where allocation and selection effects were positive for relative returns.

**Credit allocation** \| Allocations to high-quality BB-rated debt and lower-quality B-rated and CCC-debt were most additive to the Fund's relative performance.

### Top Performance Detractors
**Allocation and selection** \| Despite overall relative positive performance for the Fund, negative returns were driven by industry allocation and selection within the wirelines industry. Additional notable negative performance was seen within the media entertainment sector.

**Credit allocation** \| Some allocations to B-rated debt detracted from relative Fund performance during the period.

(c) Tax Fees include amounts for the review of annual tax returns, the review of required shareholder distribution calculations and typically include amounts for professional services by the principal accountant for tax compliance, tax advice, tax planning and foreign tax filings, if applicable.

------

(d) All Other Fees include amounts for products and services provided by the principal accountant, other than the services reported in paragraphs (a) through (c) above and typically include SOC-1 reviews.

(e)(1) Audit Committee Pre-Approval Policies and Procedures

The registrant's Audit Committee is required to pre-approve the engagement of the registrant's independent auditors to provide audit and non-audit services to the registrant and non-audit services to its investment adviser (excluding any sub-adviser whose role is primarily portfolio management and is sub-contracted or overseen by another investment adviser (the "Adviser") or any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund (a "Control Affiliate") if the engagement relates directly to the operations and financial reporting of the registrant.

The Audit Committee has adopted a Policy for Engagement of Independent Auditors for Audit and Non-Audit Services (the "Policy"). The Policy sets forth the understanding of the Audit Committee regarding the engagement of the registrant's independent accountants to provide (i) audit and permissible audit-related, tax and other services to the registrant ("Fund Services"); (ii) non-audit services to the registrant's Adviser and any Control Affiliates, that relates directly to the operations and financial reporting of a Fund ("Fund-related Adviser Services"); and (iii) certain other audit and non-audit services to the registrant's Adviser and its Control Affiliates. A service will require specific pre-approval by the Audit Committee if it is to be provided by the Fund's independent auditor; provided, however, that pre-approval of non-audit services to the Fund, the Adviser or Control Affiliates may be waived if certain de minimis requirements set forth in the SEC's rules are met.

Under the Policy, the Audit Committee may delegate pre-approval authority to any pre-designated member or members who are independent board members. The member(s) to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next regular meeting. The Audit Committee's responsibilities with respect to the pre-approval of services performed by the independent auditor may not be delegated to management.

On an annual basis, at a regularly scheduled Audit Committee meeting, the Fund's Treasurer or other Fund officer shall submit to the Audit Committee a schedule of the types of Fund Services and Fund-related Adviser Services that are subject to specific pre-approval. This schedule will provide a description of each type of service that is subject to specific pre-approval, along with total projected fees for each service. The pre-approval will generally cover a one-year period. The Audit Committee will review and approve the types of services and the projected fees for the next one-year period and may add to, or subtract from, the list of pre-approved services from time to time, based on subsequent determinations. This specific approval acknowledges that the Audit Committee is in agreement with the specific types of services that the independent auditor will be permitted to perform and the projected fees for each service.

The Fund's Treasurer or other Fund officer shall report to the Audit Committee at each of its regular meetings regarding all Fund Services or Fund-related Adviser Services provided since the last such report was rendered, including a description of the services, by category, with forecasted fees for the annual reporting period, proposed changes requiring specific pre-approval and a description of services provided by the independent auditor, by category, with actual fees during the current reporting period.

(e)(2) None, or 0%, of the Audit-Related Fees, Tax Fees and All Other Fees paid by the Fund or affiliated entities relating directly to the operations and financial reporting of the Registrant disclosed above were approved by the audit committee pursuant to paragraphs (c)(7)(i)(C) of Rule 2-01 of Regulation S-X (which permits audit committee approval after the start of the engagement with respect to services other than audit, review or attest services, if certain conditions are satisfied).

------

(f) Not applicable.

(g) The aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant and rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant.

(h) The registrant's Audit Committee of the Board of Trustees has considered whether the provision of non-audit services that were rendered to the registrant's adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, is compatible with maintaining the principal accountant's independence.

(i) Not applicable.

(j) Not applicable.

#### Item 5. Audit Committee of Listed Registrants.
The registrant is a listed issuer as defined in Section 10A-3 of the Securities Exchange Act of 1934 and has a separately designated standing Audit Committee established in accordance with Section 3(a)(58)(A) of such Act. The members of such committee are J. Kevin Connaughton, Brian J. Gallagher, Douglas A. Hacker, David M. Moffett, Amrit Kanwal and Sandra L. Yeager.

#### Item 6. Investments.

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

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

—

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

investments.

Level

—

Valuations

based

on

other

significant

observable

inputs

(including

quoted

prices

for

similar

securities,

interest

rates,

prepayment

speeds,

credit

risks,

etc.).

Level

—

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.

Investments

falling

into

the

Level

category,

if

any,

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

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

Fund's

Board of

Trustees

(the

Board)

has

designated

the

Investment

Manager,

through

its

Valuation

Committee

(the

Committee),

as

valuation

designee,

responsible

for

determining

the

fair

value

of

the

assets

of

the

Fund

for

which

market

quotations

are

not

readily

available

using

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

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.

Representatives

of

Columbia

Management

Investment

Advisers,

LLC

report

to

the

Board

at

each

of

its

regularly

scheduled

meetings

to

discuss

valuation

matters

and

actions

during

the

period,

similar

to

those

described

earlier.

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

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

—

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

investments.

Level

—

Valuations

based

on

other

significant

observable

inputs

(including

quoted

prices

for

similar

securities,

interest

rates,

prepayment

speeds,

credit

risks,

etc.).

Level

—

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.

Investments

falling

into

the

Level

category,

if

any,

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

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

Fund's

Board of

Trustees

(the

Board)

has

designated

the

Investment

Manager,

through

its

Valuation

Committee

(the

Committee),

as

valuation

designee,

responsible

for

determining

the

fair

value

of

the

assets

of

the

Fund

for

which

market

quotations

are

not

readily

available

using

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

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.

Representatives

of

at

of

The

following

table

is intended

to

help

you

understand the

Fund's

financial

performance.

Per

share

net

investment

income

(loss)

amounts

are

calculated

based

on

average

shares

outstanding

during

the

period.

Total

return

assumes

reinvestment

of

all

dividends

and

distributions,

if

any.

Total

Return

at

NAV

is

calculated

assuming

an

initial

investment

made

at

the

net

asset

value

at

the

beginning

of

the

period,

reinvestment

of

all

dividends

and

distributions

at

net

asset

value

during

the

period

and

redemption

on

the

last

day

of

the

period. The

total

return

would

have

been

lower

if

certain

expenses

had

not

been

reimbursed/waived

by

the

Investment

Manager,

if

applicable.

Total

return

and

portfolio

turnover

are

not

annualized

for

periods

of

less

than

one

year.

The

ratios

of

expenses

and

net

investment

income

are

annualized

for

periods

of

less

than

one

year.

The

portfolio

turnover

rate

is

calculated

without

regard

to

purchase

and

sales

transactions

of

short-term

instruments,

certain

derivatives

and

in-kind

transactions,

if

any.

If

such

transactions

were

included,

the

Fund's

portfolio

turnover

rate

may

be

higher.

A

The

table

is

a

summary

of

the

average monthly

outstanding

volume

by

instrument

for

the

year

ended

March

2026:

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

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

—

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

investments.

Level

—

Valuations

based

on

other

significant

observable

inputs

(including

quoted

prices

for

similar

securities,

interest

rates,

prepayment

speeds,

credit

risks,

etc.).

Level

—

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.

Investments

falling

into

the

Level

category,

if

any,

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

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

Fund's

Board of

Trustees

(the

Board)

has

designated

the

Investment

Manager,

through

its

Valuation

Committee

(the

Committee),

as

valuation

designee,

responsible

for

determining

the

fair

value

of

the

assets

of

the

Fund

for

which

market

quotations

are

not

readily

available

using

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

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.

Representatives

you

understand the

financial

performance.

Per

net

income

(loss)

amounts

are

calculated

based

on

average

shares

outstanding

during

the

period.

Total

return

assumes

reinvestment

of

all

dividends

and

distributions,

if

any.

Total

Return

at

NAV

is

calculated

assuming

an

initial

investment

made

at

the

net

asset

value

at

the

beginning

of

the

period,

reinvestment

of

all

dividends

and

distributions

at

net

asset

value

during

the

period

and

redemption

on

the

last

day

of

the

total

would

have

been

lower

if

certain

had

not

been

by

The

ratios

of

expenses

and

income

are

annualized

for

periods

of

The

is

calculated

without

regard

to

purchase

and

sales

transactions

of

short-term

instruments,

certain

derivatives

and

in-kind

transactions,

if

any.

If

such

transactions

were

included,

the

may

be

higher.

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

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

—

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

investments.

Level

—

Valuations

based

on

other

significant

observable

inputs

(including

quoted

prices

for

similar

securities,

interest

rates,

prepayment

speeds,

credit

risks,

etc.).

Level

—

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.

Investments

falling

into

the

Level

category,

if

any,

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

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

Fund's

Board of

Trustees

(the

Board)

has

designated

the

Investment

Manager,

through

its

Valuation

Committee

(the

Committee),

as

valuation

designee,

responsible

for

determining

the

fair

value

of

the

assets

of

the

Fund

for

which

market

quotations

are

not

readily

available

using

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

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.

Representatives

of

Columbia

Management

report

to

the

Board

at

of

its

regularly

scheduled

meetings

to

discuss

valuation

matters

and

actions

during

the

period,

similar

to

those

described

earlier.

The

financial

performance.

Per

amounts

are

calculated

based

on

average

shares

outstanding

during

the

period.

Total

return

assumes

reinvestment

of

all

dividends

and

distributions,

if

any.

Total

Return

at

is

calculated

assuming

an

initial

made

at

the

reinvestment

of

all

and

at

value

during

the

period

and

redemption

on

the

last

day

of

are

annualized

transactions

of

short-term

instruments,

certain

any.

If

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

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

—

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

investments.

Level

—

Valuations

based

on

other

significant

observable

inputs

(including

quoted

prices

for

similar

securities,

interest

rates,

prepayment

speeds,

credit

risks,

etc.).

Level

—

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.

Investments

falling

into

the

Level

category,

if

any,

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

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

Fund's

Board of

Trustees

(the

Board)

has

designated

the

Investment

Manager,

through

its

Valuation

Committee

(the

Committee),

as

valuation

designee,

responsible

for

determining

the

fair

value

of

the

assets

of

the

Fund

for

which

market

quotations

are

not

readily

available

using

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

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.

Representatives

of

Columbia

Management

Investment

Advisers,

LLC

report

to

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

to

help

you

understand the

Fund's

financial

performance.

Per

share

net

investment

income

(loss)

amounts

are

calculated

based

on

average

shares

outstanding

during

the

period.

Total

return

assumes

reinvestment

of

all

dividends

and

distributions,

if

any.

Total

Return

at

NAV

is

calculated

assuming

an

initial

investment

made

at

the

net

asset

value

at

the

beginning

of

the

period,

reinvestment

of

all

dividends

and

distributions

at

net

asset

value

during

the

period

and

redemption

on

the

last

day

of

the

period. The

total

return

would

have

been

lower

if

certain

expenses

had

not

been

reimbursed/waived

by

the

Investment

Manager,

if

applicable.

Total

return

and

portfolio

turnover

are

not

annualized

for

periods

of

less

than

one

year.

The

ratios

of

expenses

and

net

investment

income

are

annualized

for

periods

of

less

than

one

year.

The

portfolio

turnover

rate

is

calculated

without

regard

to

purchase

and

sales

transactions

of

short-term

instruments,

certain

derivatives

and

in-kind

transactions,

if

any.

If

such

transactions

were

included,

the

Fund's

portfolio

turnover

rate

may

be

higher.

A

zero

balance

may

reflect

an

amount

rounding

to

less

than

$0.01

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

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

—

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

investments.

Level

—

Valuations

based

on

other

significant

observable

inputs

(including

quoted

prices

for

similar

securities,

interest

rates,

prepayment

speeds,

credit

risks,

etc.).

Level

—

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.

Investments

falling

into

the

Level

category,

if

any,

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

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

Fund's

Board of

Trustees

(the

Board)

has

designated

the

Investment

Manager,

through

its

Valuation

Committee

(the

Committee),

as

valuation

designee,

responsible

for

determining

the

fair

value

of

the

assets

of

the

Fund

for

which

market

quotations

are

not

readily

available

using

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

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-

information

or

approve

related

valuation

actions.

amounts

are

calculated

based

on

average

shares

outstanding

during

the

period.

Total

return

assumes

reinvestment

of

all

dividends

and

distributions,

if

any.

Total

Return

is

calculated

assuming

value

during

the

period

and

redemption

on

the

last

day

of

the

income

are

annualized

for

and

sales

transactions

of

short-term

instruments,

certain

if

any.

If

such

may

be

higher.

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

because

the

inputs

used

to

determine

fair

value

may

not

always

be

quoted

prices

in

an

active

market.

Fair

value

inputs

are

summarized

in

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.

Investments

falling

into

the

Level

category,

if

any,

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

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

Fund's

Board of

Trustees

(the

Board)

has

designated

the

Investment

Manager,

through

its

Valuation

Committee

(the

Committee),

as

valuation

designee,

responsible

for

determining

the

fair

value

of

the

assets

of

the

Fund

for

which

market

quotations

are

not

readily

available

using

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

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-

information

or

approve

related

valuation

actions.

Representatives

outstanding

during

the

period.

Total

assumes

reinvestment

of

all

dividends

and

distributions,

if

any.

Total

Return

at

is

calculated

assuming

an

value

during

the

and

redemption

on

the

transactions

of

short-term

any.

If

such

Notes

to

Portfolio

of

Investments

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

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

—

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

investments.

Level

—

Valuations

based

on

other

significant

observable

inputs

(including

quoted

prices

for

similar

securities,

interest

rates,

prepayment

speeds,

credit

risks,

etc.).

Level

—

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.

Investments

falling

into

the

Level

category,

if

any,

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

investments

due

to

lack

of

market

transparency

and

corroboration

to

support

these

quoted

prices.

Additionally,

valuation

models

may

be

used

as

The

Fund's

Board of

Trustees

(the

Board)

has

designated

the

Investment

Manager,

through

its

Valuation

Committee

(the

Committee),

as

valuation

designee,

responsible

for

determining

the

fair

value

of

the

assets

of

the

Fund

for

which

market

quotations

are

not

readily

available

using

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

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;

(a) Non-income

(b) Valuation

(c) Represents

procedures

approved

by

the

of

Trustees.

At

March

31,

2026,

the

total

value

of

these

securities

amounted

to

$3,480,

which

represents

0.11%

of

total

net

assets.

(d) Denotes

a

restricted

security,

which

is

subject

to

legal

or

contractual

restrictions

on

resale

under

federal

laws.

Disposal

of

a

restricted

investment

may

involve

time-consuming

negotiations

and

expenses,

and

prompt

sale

at

an

acceptable

price

may

be

difficult

to

achieve.

Private

placement

securities

are

generally

considered

to

be

restricted,

although

certain

of

those

securities

may

be

traded

between

qualified

institutional

investors

under

the

provisions

of

Section

4(a)(2)

and

Rule

144A.

The

Fund

will

not

incur

any

registration

costs

upon

such

a

trade.

At

March

31,

2026,

the

total

market

value

of

these

which

represents

less

measurements

according

to

a

three-level

hierarchy

that

maximizes

the

use

of

and

minimizes

the

use

of

unobservable

inputs

by

prioritizing

that

the

most

observable

input

be

used

when

At

March

the

The

the

rate

as

of

interest

rate

represents

the

weighted

average

interest

rate

at

March

31,

2026

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.

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.

Generally,

the

Fund

is

contractually

obligated

to

receive

approval

from

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

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

—

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

investments.

Level

—

Valuations

based

on

other

significant

observable

inputs

(including

quoted

prices

for

similar

securities,

interest

rates,

prepayment

speeds,

credit

risks,

etc.).

Level

—

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.

Investments

falling

into

the

Level

category,

if

any,

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

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

Fund's

Board of

Trustees

(the

Board)

has

designated

the

Investment

Manager,

through

its

Valuation

Committee

(the

Committee),

as

valuation

designee,

responsible

for

determining

the

fair

value

of

the

assets

of

the

Fund

for

which

market

quotations

are

not

readily

available

using

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

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.

Representatives

of

Columbia

Management

Investment

Advisers,

LLC

report

to

the

Board

at

each

of

its

regularly

scheduled

meetings

to

discuss

valuation

matters

and

actions

during

the

period,

similar

to

those

described

earlier.

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.

example,

certain

U.S.

government

securities

are

generally

high

quality

and

liquid,

however,

they

are

reflected

as

Level

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

—

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

investments.

Level

—

Valuations

based

on

other

significant

observable

inputs

(including

quoted

prices

for

similar

securities,

interest

rates,

prepayment

speeds,

credit

risks,

etc.).

Level

—

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.

Investments

falling

into

the

Level

category,

if

any,

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

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

Fund's

Board of

Trustees

(the

Board)

has

designated

the

Investment

Manager,

through

its

Valuation

Committee

(the

Committee),

as

valuation

designee,

responsible

for

determining

the

fair

value

of

the

assets

of

the

Fund

for

which

market

quotations

are

not

readily

available

using

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

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.

are

prepared

in

accordance

with

U.S.

generally

accepted

accounting

principles

(GAAP),

which

requires

management

to

make

certain

estimates

and

assumptions

that

affect

the

reported

the

The

CODM

has

determined

that

the

a

because

the

monitors

the

Debt

securities

generally

are

valued

based

on

prices

obtained

from

pricing

services,

which

are

intended

to

reflect

market

transactions

for

normal,

institutional-size

trading

units

of

similar

securities.

The

services

may

use

various

pricing

techniques

that

take

into

account,

as

applicable,

factors

such

as

yield,

quality,

coupon

rate,

maturity,

type

of

issue,

trading

characteristics

and

other

quotes.

Debt

securities

for

which

quotations

are

not

readily

available

or

not

of

market

value

may

also

be

valued

based

upon

a

bid

quote

from

an

approved

independent

broker-dealer.

Debt

securities

maturing

in

days

or

less

are

valued

primarily

at

amortized

market

value,

unless

this

method

results

in

a

valuation

that

management

believes

does

not

approximate

fair

value.

Asset-

and

mortgage-backed

securities

are

generally

valued

by

pricing

services,

which

utilize

pricing

models

that

incorporate

the

securities'

cash

flow

and

loan

performance

data.

These

models

also

take

into

account

available

market

data,

including

trades,

market

quotations,

and

benchmark

yield

curves

for

identical

or

similar

securities.

Factors

used

to

identify

similar

securities

may

include,

but

are

not

limited

to,

issuer,

collateral

type,

vintage,

prepayment

speeds,

collateral

performance,

credit

ratings,

credit

enhancement

and

expected

Asset-backed

securities

for

which

quotations

Senior

loan

securities

for

which

reliable

market

quotations

are

readily

available

are

generally

valued

by

pricing

services

at

the

average

of

the

bids

received.

Investments

in

open-end

investment

companies

(other

than

exchange-traded

funds

(ETFs)),

are

valued

at

the

latest

net

asset

value

reported

by

those

companies

as

of

the

valuation

time.

Futures

and

options

on

futures

contracts

are

valued

based

upon

the

settlement

price

at

the

close

of

regular

trading

on

their

principal

exchanges

or,

in

the

absence

of

a

settlement

price,

at

the

mean

of

the

latest

quoted

bid

and

ask

prices.

Investments

for

which

market

quotations

are

not

readily

available,

or

that

have

quotations

which

management

believes

are

not

reflective

of

market

value

or

reliable,

are

valued

at

fair

value

as

determined

in

good

faith

under

procedures

approved

by

the

Board

of

Trustees.

If

a

security

or

class

of

securities

(such

as

foreign

securities)

is

valued

at

fair

value,

such

value

is

likely

to

be

different

from

the

quoted

or

published

price

for

the

security,

if

available.

The

determination

of

fair

value

often

requires

significant

judgment.

To

determine

fair

value,

management

may

use

assumptions

including

but

not

limited

to

future

cash

flows

and

estimated

risk

premiums.

Multiple

inputs

from

various

sources

may

be

used

to

determine

fair

value.

GAAP

requires

disclosure

regarding

the

inputs

and

valuation

techniques

used

to

measure

fair

value

and

any

changes

in

valuation

inputs

or

Derivative

instruments

Certain

Funds

invest

in

certain

derivative

instruments,

as

detailed

below,

in

seeking

to

meet their

investment

objectives.

Derivatives

are

instruments

whose

values

depend

on,

or

are

derived

from,

in

whole

or

in

part,

the

value

of

one

or

more

securities,

currencies,

commodities,

indices,

or

other

assets

or

instruments.

Derivatives

may

be

used

to

increase

investment

flexibility

(including

to

maintain

cash

reserves

while

maintaining

desired

exposure

to

certain

assets),

for

risk

management

(hedging)

purposes,

to

facilitate

trading,

to

reduce

transaction

costs

and

to

pursue

higher

investment

returns. A

Fund

may

also

use

derivative

instruments

to

mitigate

certain

investment

risks,

such

as

foreign

currency

exchange

rate

risk,

interest

rate

risk

and

credit

risk.

Derivatives

may

involve

various

risks,

including

the

potential

inability

of

the

counterparty

to

fulfill

its

obligations

under

the

terms

of

the

contract,

the

potential

for

an

illiquid

secondary

market

(making

it

difficult

for

a

Fund

to

sell

or

terminate,

including

at

favorable

prices)

and

the

potential

for

market

movements

which

may

expose

a

Fund

to

gains

or

losses

in

excess

of

the

amount

shown

in

the

Statement

of

Assets

and

Liabilities.

The

notional

exposure

of

a

financial

instrument

is

the

nominal

or

face

amount

that

is

used

to

calculate

payments

made

on

that

instrument

and/or

changes

in

value

for

the

instrument.

The

notional

exposure

is

a

hypothetical

underlying

quantity

upon

which

payment

obligations

are

computed.

Notional

exposures

provide

a

gauge

for

how a

Fund

may

behave

given

changes

in

the

underlying

rate,

asset

or

reference

instrument

and

individual

markets.

The

notional

amounts

of

derivative

instruments,

if

applicable,

are

not

recorded

in

the

financial

statements.

A

derivative

instrument

may

suffer

a

marked-to-market

loss

if

the

value

of

the

contract

decreases

due

to

an

unfavorable

change

in

the

market

rates

or

values

of

the

underlying

instrument.

Losses

can

also

occur

if

the

counterparty

does

not

perform

its

obligations

under

the

contract. A

Fund's

risk

of

loss

from

counterparty

credit

risk

on

over-the-counter

derivatives

is

generally

expected

to

be

limited

to

the

aggregate

unrealized

gain

netted

against

any

collateral

held

by a

Fund

and

the

amount

of

any

variation

margin

held

by

the

counterparty,

plus

any

replacement

costs

or

related

amounts.

With

exchange-

traded

or

centrally

cleared

derivatives,

there

is

reduced

counterparty

credit

risk

to a

Fund

since

the

clearinghouse

or

central

counterparty

provides

some

protection

in

the

case

of

clearing

member

default.

The

clearinghouse

or

central

counterparty

stands

between

the

buyer

and

the

seller

of

the

contract;

therefore,

failure

of

the

clearinghouse

or

central

counterparty

may

pose

additional

counterparty

credit

risk.

However,

credit

risk

still

exists

in

exchange-traded

or

centrally

cleared

derivatives

with

respect

to

initial

and

variation

margin

that

is

held

in

a

broker's

customer

account.

While

clearing

brokers

are

required

to

segregate

customer

margin

from

their

own

assets,

in

the

event

that

a

clearing

broker

becomes

insolvent

or

goes

into

bankruptcy

and

at

that

time

there

is

a

shortfall

in

the

aggregate

amount

of

margin

held

by

the

clearing

broker

for

all

its

clients

and

such

shortfall

is

remedied

by

the

central

counterparty

or

otherwise,

U.S.

bankruptcy

laws

will

typically

allocate

that

shortfall

on

a

pro-rata

basis

across

all

the

clearing

broker's

customers

(including

the

Funds),

potentially

resulting

in

losses

to

the

Funds.

In

order

to

better

define

its

contractual

rights

and

to

secure

rights

that

will

help a

Fund

mitigate

its

counterparty

risk

in

respect

of

over-the-counter

derivatives, a

Fund

may

enter

into

an

International

Swaps

and

Derivatives

Association,

Inc.

Master

Agreement

(ISDA

Master

Agreement)

or

similar

agreement

with

its

derivatives

counterparties.

An

ISDA

Master

Agreement

is

an

agreement

between a

Fund

and

a

counterparty

that

governs

over-the-counter

derivatives

and

foreign

exchange

forward

contracts

and

contains,

among

other

things,

collateral

posting

terms

and

netting

provisions

in

the

event

of

a

default

and/or

termination

event.

Under

an

ISDA

Master

Agreement, a

Fund

may,

under

certain

circumstances,

offset

with

the

counterparty

certain

derivative

instruments'

payables

and/or

receivables

with

collateral

held

and/or

posted

and

create

one

single

net

payment.

The

provisions

of

the

ISDA

Master

Agreement

typically

permit

a

single

net

payment

in

the

event

of

default

(close-out

netting),

including

the

bankruptcy

or

insolvency

of

the

counterparty.

Note,

however,

that

bankruptcy

or

insolvency

laws

of

a

particular

jurisdiction

may

impose

restrictions

on

or

prohibitions

against

the

right

of

offset

or

netting

in

bankruptcy,

insolvency

or

other

events.

Collateral

(margin)

requirements

differ

by

type

of

derivative.

Margin

requirements

are

established

by

the

clearinghouse

or

central

counterparty

for

exchange-traded

and

centrally

cleared

derivatives.

Brokers

can

ask

for

margin

in

excess

of

the

minimum

in

certain

circumstances.

Collateral

terms

for

most

over-the-counter

derivatives

are

subject

to

regulatory

requirements

to

exchange

variation

margin

with

trading

counterparties

and

may

have

contract

specific

margin

terms

as

well.

For

over-the-counter

derivatives

traded

under

an

ISDA

Master

Agreement,

the

collateral

requirements

are

typically

calculated

by

netting

the

marked-to-market

amount

for

each

transaction

under

such

agreement

and

comparing

that

amount

to

the

value

of

any

variation

margin

currently

pledged

by a

Fund

and/or

the

counterparty.

Generally,

the

amount

of

collateral

due

from

or

to

a

party

has

to

exceed

a

minimum

transfer

amount

threshold

(e.g.,

$250,000)

before

a

transfer

has

to

be

made.

To

the

extent

amounts

due

to a

Fund

from

its

counterparties

are

not

fully

collateralized,

contractually

or

otherwise, a

Fund

bears

the

risk

of

loss

from

counterparty

nonperformance. A

Fund

may

also

pay

interest

expense

on

cash

collateral

received

from

the

broker

or

receive

interest

income

on

cash

collateral

pledged

to

the

broker. A

Fund

attempts

to

mitigate

counterparty

risk

by

only

entering

into

agreements

with

counterparties

that

it

believes

have

the

financial

resources

to

honor

their

obligations

and

by

monitoring

the

financial

stability

of

those

counterparties.

Certain

ISDA

Master

Agreements

allow

counterparties

of

over-the-counter

derivatives

transactions

to

terminate

derivatives

contracts

prior

to

maturity

in

the

event a

Fund's

net

asset

value

declines

by

a

stated

percentage

over

a

specified

time

period

or

if a

Fund

fails

to

meet

certain

terms

of

the

ISDA

Master

Agreement,

which

would

cause a

Fund

to

accelerate

payment

of

any

net

liability

owed

to

the

counterparty.

A

Fund

also

has

termination

rights

if

the

counterparty

fails

to

meet

certain

terms

of

the

ISDA

Master

Agreement.

In

determining

whether

to

exercise

such

termination

rights, a

Fund

would

consider,

in

addition

to

counterparty

credit

risk,

whether

termination

would

result

in

a

net

liability

owed

from

the

counterparty.

For

financial

reporting

purposes, a

Fund

does

not

offset

derivative

assets

and

derivative

liabilities

that

are

subject

to

netting

arrangements

in

the

Statement

of

Assets

and

Liabilities.

Futures

contracts

Futures

contracts

are

exchange-traded

and

represent

commitments

for

the

future

purchase

or

sale

of

an

asset

at

a

specified

price

on

a

specified

date.

Certain

Funds

bought

and

sold

futures

contracts

to

manage

exposure

to

the

securities

markets

or

to

movements

in

interest

rates

and

currency

values.

Funds

invest

in

futures

contracts

as

part

of

their

primary

investment

strategy

and/or

to

equitize

their

cash

flows.

Investments

in

futures

contracts

may

increase

or

decrease

exposure

to

a

particular

market.

These

instruments

may

be

used

for

other

purposes

in

future

periods.

Upon

entering

into

futures

contracts,

a

Fund

bears

risks

that

it

may

not

achieve

the

anticipated

benefits

of

the

futures

contracts

and

may

realize

a

loss.

Additional

risks

include

counterparty

credit

risk,

the

possibility

of

an

illiquid

market,

and

that

a

change

in

the

value

of

the

contract

or

option

may

not

correlate

with

changes

in

the

value

of

the

underlying

asset.

Upon

entering

into

a

futures

contract,

a

Fund

deposits

cash

or

securities

with

the

broker,

known

as

a

futures

commission

merchant

(FCM),

in

an

amount

sufficient

to

meet

the

initial

margin

requirement.

The

initial

margin

deposit

must

be

maintained

at

an

established

level

over

the

life

of

the

contract.

Cash

deposited

as

initial

margin

is

recorded

in

the

Statement

of

Assets

and

Liabilities

as

margin

deposits.

Securities

deposited

as

initial

margin

are

designated

in

the

Portfolio

of

Investments.

Subsequent

payments

(variation

margin)

are

made

or

received

by a

Fund

each

day.

The

variation

margin

payments

are

equal

to

the

daily

change

in

the

contract

value

and

are

recorded

as

variation

margin

receivable

or

payable

and

are

offset

in

unrealized

gains

or

losses.

The

Funds

generally

expect

to

earn

interest

income

on

their

margin

deposits.

The

Funds

recognize

a

realized

gain

or

loss

when

the

contract

is

closed

or

expires.

Futures

contracts

involve,

to

varying

degrees,

risk

of

loss

in

excess

of

the

variation

margin

disclosed

in

the

Statement

of

Assets

and

Liabilities.

Options

contracts

which

and

put

options

on

securities

and

financial

instruments

it

owns

or

in

which

it

may

tends

to

increase

a

Fund's

exposure

to

the

Writing

call

options

tends

to

decrease

exposure

to

the

When

Completion

of

transactions

for

contracts

traded

in

the

upon

the

risk

in

writing

a

put

option

contract

is

that a

Fund

may

incur

a

loss

if

the

market

price

of

the

security

decreases

below

the

strike

price

and

the

option

contract

is

exercised.

Exercise

of

a

written

option

could

result

in

the

Fund

purchasing

or

selling

a

security

or

foreign

currency

when

it

otherwise

would

not,

or

at

a

price

different

from

the

current

market

value.

In

purchasing

and

writing

options,

the

Fund

bears

the

risk

of

an

unfavorable

change

in

the

value

of

the

underlying

instrument

or

the

risk

that

the

Fund

may

not

be

able

to

enter

into

a

closing

transaction

due

to

an

illiquid

market.

Asset-

and

mortgage-backed

securities

Certain

Funds may

invest

in

asset-backed

and

mortgage-backed

securities.

The

maturity

dates

shown

represent

the

original

maturity

of

the

underlying

obligation.

Actual

maturity

may

vary

based

upon

prepayment

activity

on

these

obligations.

All,

or

a

portion,

of

the

obligation

may

be

prepaid

at

any

time

because

the

underlying

asset

may

be

prepaid.

As

a

result,

decreasing

market

interest

rates

could

result

in

an

increased

level

of

prepayment.

An

increased

prepayment

rate

will

have

the

effect

of

shortening

the

maturity

of

the

security.

Unless

otherwise

noted,

the

coupon

rates

presented

are

fixed

rates.

Delayed

delivery

securities

Certain

Funds

may

trade

securities

on

other

than

normal

settlement

terms,

including

securities

purchased

or

sold

on

a

"when-issued"

or

"forward

commitment"

basis.

This

may

increase

risk

to

the

Fund

since

the

other

party

to

the

transaction

may

fail

to

deliver,

which

could

cause

the

Fund

to

subsequently

invest

at

less

advantageous

prices.

The

Fund

designates

cash

or

liquid

securities

in

an

amount

equal

to

the

delayed

delivery

commitment.

To

be

announced

securities

Certain

Funds may

trade

securities

on

a

To

Be

Announced

(TBA)

basis.

As

with

other

delayed-delivery

transactions,

a

seller

agrees

to

issue

a

TBA

security

at

a

future

date.

However,

the

seller

does

not

specify

the

particular

securities

to

be

delivered.

Instead,

the

Fund

agrees

to

accept

any

security

that

meets

specified

terms.

In

some

cases,

Master

Securities

Forward

Transaction

Agreements

(MSFTAs)

may

be

used

to

govern

transactions

of

certain

forward-settling

agency

mortgage-backed

securities,

such

as

delayed-delivery

and

TBAs,

between

the

Fund

and

counterparty.

The

MSFTA

maintains

provisions

for,

among

other

things,

initiation

and

confirmation,

payment

and

transfer,

events

of

default,

termination,

and

maintenance

of

collateral

relating

to

such

transactions.

Mortgage

dollar

roll

transactions

Certain

Funds may

enter

into

mortgage

"dollar

rolls"

in

which

the

Fund

sells

securities

for

delivery

in

the

current

month

and

simultaneously

contracts

with

the

same

counterparty

to

repurchase

similar

but

not

identical

securities

(same

type,

coupon

and

maturity)

on

a

specified

future

date.

These

transactions

may

increase

the

Fund's

portfolio

turnover

rate.

During

the

roll

period,

the

Fund

loses

the

right

to

receive

principal

and

interest

paid

on

the

securities

sold.

However,

the

Fund

may

benefit

because

it

receives

negotiated

amounts

in

the

form

of

reductions

of

the

purchase

price

for

the

future

purchase

plus

the

interest

earned

on

the

cash

proceeds

of

the

securities

sold

until

the

settlement

date

of

the

forward

purchase.

The

Fund

records

the

incremental

difference

between

the

forward

purchase

and

sale

of

each

forward

roll

as

a

realized

gain

or

loss.

Unless

any

realized

gains

exceed

the

income,

capital

appreciation,

and

gain

or

loss

due

to

mortgage

prepayments

that

would

have

been

realized

on

the

securities

sold

as

part

of

the

mortgage

dollar

roll,

the

use

of

this

technique

may

diminish

the

investment

performance

of

the

Fund

compared

to

what

the

performance

would

have

been

without

the

use

of

mortgage

dollar

rolls.

Mortgage

Interest

only

and

principal

only

securities

Certain

Funds may

invest

in

Interest

Only

(IO)

or

Principal

Only

(PO)

securities.

IOs

are

stripped

securities

entitled

to

receive

all

of

the

security's

interest,

but

none

of

its

principal.

IOs

are

particularly

sensitive

to

changes

in

interest

rates

and

therefore

subject

to

greater

fluctuations

in

price

than

typical

interest

bearing

debt

securities.

IOs

are

also

subject

to

credit

risk

because

the

Fund

may

not

receive

all

or

part

of

the

interest

payments

if

the

issuer,

obligor,

guarantor

or

counterparty

defaults

on

its

obligation.

Payments

received

for

IOs

are

included

in

interest

income

in

the

Statement

of

Operations.

Because

no

principal

will

be

received

at

the

maturity

of

an

IO,

adjustments

are

made

to

the

cost

of

the

security

on

a

monthly

basis

until

maturity.

These

adjustments

are

included

in

interest

income

in

the

Statement

of

Operations.

POs

are

stripped

securities

entitled

to

receive

the

principal

from

the

underlying

obligation,

but

not

the

interest.

POs

are

particularly

sensitive

to

changes

in

interest

rates

and

therefore

are

subject

to

fluctuations

in

price.

POs

are

also

subject

to

credit

risk

because

the

Fund

may

not

receive

all

or

part

of

its

principal

if

the

issuer,

obligor,

guarantor

or

counterparty

defaults

on

its

obligation.

The

Fund

may

also

invest

in

IO

or

PO

stripped

mortgage-backed

securities.

Payments

received

for

POs

are

treated

as

reductions

to

the

cost

and

par

value

of

the

securities.

Investments

in

senior

loans

Certain

Funds

may

invest

in

senior

loan

assignments.

When

the

Fund

purchases

an

assignment

of

a

senior

loan,

the

Fund

typically

has

direct

rights

against

the

borrower;

provided,

however,

that

the

Fund's

rights

may

be

more

limited

than

the

lender

from

which

it

acquired

the

assignment

and

the

Fund

may

be

able

to

enforce

its

rights

only

through

an

administrative

agent.

Although

certain

senior

loan

assignments

are

secured

by

collateral,

the

Fund

could

experience

delays

or

limitations

in

realizing

such

collateral

or

have

its

interest

subordinated

to

other

indebtedness

of

the

obligor.

In

the

event

that

the

administrator

or

collateral

agent

of

a

loan

becomes

insolvent

or

enters

into

receivership

or

bankruptcy,

the

Fund

may

incur

costs

and

delays

in

realizing

payment

or

may

suffer

a

loss

of

principal

and/or

interest.

The

risk

of

loss

is

greater

for

unsecured

or

subordinated

loans.

In

addition,

senior

loan

assignments

are

vulnerable

to

market,

economic

or

other

conditions

or

events

that

may

reduce

the

demand

for

senior

loan

assignments

and

certain

senior

loan

assignments

which

were

liquid

when

purchased,

may

become

illiquid.

The

Fund

may

enter

into

senior

loan

assignments

where

all

or

a

portion

of

the

loan

may

be

unfunded.

The

Fund

is

obligated

to

fund

these

commitments

at

the

borrower's

discretion.

These

commitments,

if

any,

are

generally

traded

and

priced

in

the

same

manner

as

other

senior

loan

securities

and

are

disclosed

as

unfunded

senior

loan

commitments

in

the

Fund's

Portfolio

of

Investments

with

a

corresponding

payable

for

investments

purchased.

The

Fund

designates

cash

or

liquid

securities

to

cover

these

commitments.

Security

transactions

Security

transactions

are

accounted

for

on

the

trade

date.

Cost

is

determined

and

gains

(losses)

are

based

upon

the

specific

identification

method

for

both

financial

statement

and

federal

income

tax

purposes.

The

trade

date

for

senior

loans

purchased

in

market

is

the

date

on

which

the

is

allocated.

The

date

for

Corporate

income

are

generally

recorded

of

any

non-reclaimable

tax

withholdings,

on

the

ex-

dividend

date

or

upon

receipt

of

an

ex-dividend

notification

in

Awards

are

recorded

as

a

if

If

The

estimates

are

subsequently

adjusted

when

the

actual

character

of

the

is

disclosed

by

the

REITs,

which

could

result

in

a

proportionate

change

in

return

of

capital

to

Interest

income

is

recorded

on

an

accrual

basis.

Market

premiums

and

discounts,

including

original

issue

discounts,

are

amortized

and

accreted,

respectively,

over

the

expected

life

of

the

security

on

all

debt

securities,

unless

otherwise

noted. Certain

Funds

classify gains

and

losses

realized

on

prepayments

received

on

mortgage-backed

securities

as

adjustments

to

interest

income. Certain

Funds

may

place

a

debt

security

on

non-accrual

status

and

reduce

related

interest

income

when

it

becomes

probable

that

the

interest

will

not

be

collected

and

the

amount

of

uncollectible

interest

can

be

reasonably

estimated.

The

Fund

may

also

adjust

accrual

rates

when

it

becomes

probable

the

full

interest

will

not

be

collected

and

a

partial

payment

will

be

received.

A

defaulted

debt

security

is

removed

from

non-accrual

status

when

the

issuer

resumes

interest

payments

or

when

collectability

of

interest

is

reasonably

assured.

The

value

of

additional

securities

received

as

an

income

payment

through

a

payment-in-kind,

if

any, is

recorded

as

interest

income

and

increases

of

such

securities.

Certain

Funds may

receive

other

income

from

senior

loans,

including

amendment

fees,

consent

fees

and

fees.

These

fees

are

recorded

as

income

when

received

by

the

Fund.

These

amounts

are

included

in

Determination

of

value

The

net

asset

value

per

is

computed

by

dividing

the

value

of

the

net

assets

of

each

Fund by

the

total

number

of

outstanding

of

the

Fund,

rounded

Federal

income

tax

status

For

federal

income

tax

purposes,

each

Fund

is

treated

as

a

separate

entity.

The

Funds

intend

to

qualify

each

year

as

separate

regulated

investment

companies

under

Subchapter

M

of

the

Internal

Revenue

Code,

as

will

distribute

substantially

all

annually.

Income

distributions

and

capital

gain

distributions

are

determined

in

are

indemnified

against

certain

approved

a

plan

of

reorganization

at

held

in

Board

unanimously

approved

the

reorganization

based

on

its

determination

that

it

is

in

best

interest

of

Fund

shareholders.

Expected

benefits

of

the

reorganization

include

a

lower

net

annual

fund

operating

ratio

and

improved

tax

efficiency.

The

Fund

has

objective

and

substantially

similar

The

aggregate

net

assets

of

the

at

was

accomplished

by

of

the

Acquired

Fund

valued

at

$1,391,288,884

of

unrealized

depreciation).

In

exchange

for

the

Acquired

Fund's

shares,

the

Fund

issued

46,128,328

shares.

For

reporting

purposes,

issued

by

were

recorded

at

value;

however,

the

Acquired

Note

11. Risks

and

uncertainties

An

investment

in

the

Funds

involve

risks,

including

market

risk

and

concentration

risk,

among

others.

The

value

of

each

Fund's

holdings

and

each

Fund's

NAV

may

go

down.

These

declines

may

be

due

to

factors

affecting

a

particular

issuer,

or

the

result

of,

among

other

things,

political,

regulatory,

market,

economic

or

social

developments

affecting

the

relevant

market(s)

more

generally.

Global

economies

and

financial

markets

are

increasingly

interconnected,

and

conditions

and

events

in

one

country,

region

or

financial

market

may

adversely

impact

issuers

in

a

different

country,

region

or

financial

market.

These

risks

may

be

magnified

if

certain

events

or

developments

adversely

interrupt

the

global

supply

chain;

in

these

and

other

circumstances,

such

risks

might

affect

companies

worldwide.

As

a

result,

local,

regional

or

global

events

such

as

terrorism,

war,

other

conflicts,

natural

disasters,

disease/virus

outbreaks

and

epidemics

or

other

public

health

issues,

recessions,

depressions

or

other

events

–

or

the

potential

for

such

events

–

could

have

a

significant

negative

impact

on

global

economic

and

market

conditions.

To

the

extent

that

each

Fund

concentrates

its

investment

in

particular

issuers,

countries,

geographic

regions,

industries

or

sectors,

each

Fund

may

be

subject

to

greater

risks

of

adverse

developments

in

such

areas

of

focus

than

a

fund

that

invests

in

a

wider

variety

of

issuers,

countries,

geographic

regions,

industries,

sectors

or

investments.

Additional

risk

factors

of

each

Fund

are

described

fully

the

respective

Fund's Prospectus

and

Statement

of

Additional

Information.

the

considered

relating

renewal

of

advisory

with

respect

to

and,

legal

of

the

factors

that

should

be

considered

in

determining

whether

to

approve

The

Independent

considered

such

information

as

they,

their

legal

counsel

or

the

Investment

Manager

believed

reasonably

necessary

to

evaluate

and

to

approve

the

IMS

Agreement.

Among

other

things,

the

information

and

factors

considered

included

the

following:

Information

on

the

Fund's

proposed

management

fees

and

anticipated

total

expenses;

Terms

of

the

Descriptions

of

including

Information

regarding

including

information

regarding

portfolio

and

other

personnel;

and

Information

regarding

the

capabilities

of

the

Investment

Manager

with

respect

to

compliance

monitoring

services.

Following

an

analysis

and

discussion

of

the

foregoing,

and

the

factors

identified

below,

the

Board,

including

all

of

the

Independent

Trustees,

approved

the

IMS

Agreement.

Nature,

extent

and

quality

of

services

provided

by

the

Investment

Manager

The

Board

analyzed

various

reports

and

presentations

it

had

received

detailing

the

services

to

be

performed

by

the

Investment

Manager,

as

well

as

its

history,

expertise,

resources

and

relative

capabilities,

and

the

qualifications

of

its

personnel.

The

Board

specifically

considered

the

many

developments

during

recent

years

concerning

the

services

provided

by

the

Investment

Manager

to

the

Columbia

Funds.

Among

other

things,

the

Board

noted

the

organization

and

depth

of

the

equity

and

credit

research

departments.

The

Board

further

observed

the

enhancements

to

the

investment

risk

management

department's

processes,

systems

and

oversight,

over

the

past

several

years.

The

Board

also

took

into

account

the

broad

scope

of

services

provided

by

the

Investment

Manager

to

the

Fund,

including,

among

other

services,

investment,

risk

and

Approval

compliance

oversight.

The

Board

also

took

into

account

the

information

it

received

concerning

the

Investment

Manager's

ability

to

attract

and

retain

key

portfolio

management

personnel

and

that

it

has

sufficient

resources

to

provide

competitive

and

adequate

compensation

to

investment

personnel.

The

Board

also

considered

the

oversight

of

the

administrative

and

transfer

agency

services

to

be

provided

by

State

Street

Bank

and

Trust

Company

(SSBT).

The

Board

noted

its

review

at

meetings

in

July

and

August

of

2025

of

the

quality

of

services

to

be

provided

by

SSBT,

which

was

proposed

to

serve

as

the

transfer

agent,

custodian

and

administrator

for

the

Fund.

In

evaluating

the

quality

of

services

to

be

provided

under

the

IMS

Agreement,

the

Board

also

took

into

account

the

organization

and

strength

of

the

Fund's

and

its

service

providers'

compliance

programs.

The

Board

also

reviewed

the

financial

condition

of

the

Investment

Manager

and

its

affiliates

and

each

entity's

ability

to

carry

out

its

responsibilities

under

the

IMS

Agreement

and

the

Fund's

other

service

agreements.

In

addition,

the

Board

discussed

the

acceptability

of

the

terms

of

the

IMS

Agreement,

including

the

relatively

broad

scope

of

services

required

to

be

performed,

as

well

as

each

of

the

other

proposed

agreements

and

plans

for

the

Fund.

The

Board

observed

that

the

proposed

agreements

and

plans

were

substantively

identical

to

the

form

of

existing

agreements

and

plans

with

respect

to

other

series

of

the

Trust

discussed

at

its

June

meeting

or,

in

the

case

of

those

agreements

with

SSBT,

discussed

at

its

meeting

on

August

26,

2025. The

Board

also

noted

the

wide

array

of

legal

and

compliance

services

provided

by

the

Investment

Manager

to

such

series.

After

reviewing

these

and

related

factors

(including

investment

performance

as

discussed

below),

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

nature,

extent

and

quality

of

the

services

to

be

provided

to

the

Fund

under

the

IMS

Agreement

supported

the

approval

of

the

IMS

Agreement.

Investment

performance

Because

the

Fund

had

not

yet

commenced

operations,

the

Board

did

not

have

investment

performance

to

compare

to

the

returns

of

a

group

of

comparable

funds.

The

Board

also

considered

the

Investment

Manager's

performance

and

reputation

generally,

the

Investment

Manager's

historical

responsiveness

to

Board

concerns

about

performance,

and

the

Investment

Manager's

willingness

to

take

steps

intended

to

improve

performance.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

performance

of

the

Investment

Manager,

in

light

of

other

considerations,

supported

the

approval

of

the

IMS

Agreement.

Comparative

fees,

costs

of

services

provided

and

the

profits

realized

by

the

Investment

Manager

and

its

affiliates

from

their

relationships

with

the

Fund

The

Board

reviewed

comparative

fees

and

the

costs

of

services

to

be

provided

under

the

IMS

Agreement.

The

Board

considered

the

proposed

unitary

fee

structure

to

be

utilized

by

the

Fund,

observing

that

many

of

the

competitors

of

the

Fund

have

adopted

similar

unitary

fee

structures.

The

Board

accorded

particular

weight

to

the

notion

that

a

primary

objective

of

the

proposed

level

of

fees

is

to

achieve

a

rational

pricing

model

applied

consistently

across

the

various

product

lines

in

the

Fund

family,

while

assuring

that

the

overall

fees

for

each

Columbia

Fund

(with

certain

exceptions)

are

generally

in

line

with

the

current

"pricing

philosophy"

such

that

Fund

total

expense

ratios,

in

general,

approximate

or

are

lower

than

the

median

expense

ratios

of

funds

in

the

same

Lipper

comparison

universe.

The

Board

considered

that

the

proposed

unitary

fee

approximated

the

median

net

expense

ratio

of

the

Fund's

peer

ETFs

and

remained

competitive

with

similar

strategies.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

proposed

levels

of

management

fees

and

expenses

of

the

Fund,

in

light

of

other

considerations,

supported

the

approval

of

the

IMS

Agreement.

The

Board

took

into

account

the

indirect

economic

benefits

flowing

to

the

Investment

Manager

or

its

affiliates

in

connection

with

managing

the

Columbia

Funds,

such

as

the

enhanced

ability

to

offer

various

other

financial

products

to

Ameriprise

Financial

customers

and

overall

reputational

advantages.

They

noted

that

the

fees

to

be

paid

by

the

Fund

should

permit

the

Approval

of

Manager

to

offer

competitive

compensation

to

its

personnel,

make

necessary

investments

in

its

business

and

earn

an

appropriate

profit.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

costs

of

services

to

be

provided

supported

the

approval

of

the

IMS

Agreement.

Economies

of

scale

The

Board

considered

that

the

proposed

IMS

Agreement

provides

for

a

unitary

fee

level

that

does

not

include

pre-

established

breakpoints,

and

management's

observation

that

ETF

fee

structures

often

do

not

include

breakpoints

due

to

the

more

volatile

nature

of

their

inflows/outflows.

Conclusion

The

Board

reviewed

all

of

the

above

considerations

in

reaching

its

decision

to

approve

the

IMS

Agreement.

In

reaching

its

conclusions,

no

single

factor

was

determinative.

On

November

6,

2025,

the

Board,

including

all

of

the

Independent

Trustees,

determined

that

fees

payable

under

the

IMS

Agreement

were

fair

and

reasonable

in

light

of

the

extent

and

quality

of

services

provided

and

2025,

the

Board

of

Trustees

(the

Board),

including

the

independent

Board

members

(the

Independent

Trustees),

of

Columbia

ETF

Trust

I

(the

Trust)

unanimously

approved,

for

an

initial

two-year

term,

the

IMS

Agreement

with

the

Investment

Manager

with

respect

to

the

Fund,

a

series

of

the

Trust.

As

detailed

below,

the

Board

and

the

Board's

Investment

Review

Committee

met

to

review

and

discuss,

both

among

themselves

and

with

the

management

team

of

the

Investment

Manager,

materials

provided

by

the

Investment

Manager

before

determining

to

approve

the

IMS

Agreement.

The

Board

also

considered

the

proposal

to

reorganize

Columbia

Bond

Fund

(the

Predecessor

Fund)

into

the

Fund.

In

connection

with

their

deliberations

regarding

the

proposed

IMS

Agreement,

the

Committee

and

the

Board

evaluated

materials

requested

from

the

Investment

Manager

regarding

the

Fund

and

the

IMS

Agreement,

and

discussed

these

materials

with

representatives

of

the

Investment

Manager

at

the

June

2025

Investment

Review

Committee

and

full

Board

meetings

(the

June

Meeting)

and

the

September

2025

Investment

Review

Committee

and

full

Board

meetings

(the

September

Meeting,

and,

together

with

the

June

Meeting,

the

Meetings).

The

Independent

Trustees

also

considered

the

discussion

relating

to

the

renewal

of

advisory

agreements

for

other

series

of

the

Trust

at

the

June

Meeting.

The

Committee

and

the

Board

also

consulted

with

the

Independent

Trustees'

independent

legal

counsel,

who

advised

on

various

matters

with

respect

to

the

Committee's

and

the

Board's

considerations

and

otherwise

assisted

the

Committee

and

the

Board

in

their

deliberations.

The

Board

considered

its

discussion

relating

to

the

renewal

of

advisory

agreements

with

respect

to

other

series

of

the

Trust

and,

in

that

connection,

the

discussion

by

independent

legal

counsel

of

the

factors

that

should

be

considered

in

determining

whether

to

approve

or

renew

an

investment

management

agreement.

The

Independent

Trustees

considered

such

information

as

they,

their

legal

counsel

or

the

Investment

Manager

believed

reasonably

necessary

to

evaluate

and

to

approve

the

IMS

Agreement.

Among

other

things,

the

information

and

factors

considered

included

the

following:

Information

on

the

Fund's

proposed

management

fees

and

anticipated

total

expenses;

Terms

of

the

IMS

Agreement;

Descriptions

of

various

services

performed

by

the

Investment

Manager

under

the

IMS

Agreement,

including

portfolio

management

and

portfolio

trading

practices;

Information

regarding

the

resources

of

the

Investment

Manager,

including

information

regarding

senior

management,

portfolio

managers

and

other

personnel;

Information

regarding

the

capabilities

of

the

Investment

Manager

with

respect

to

compliance

monitoring

services;

and

Information regarding

the

proposed

reorganization

of

the

Predecessor

Fund

into

the

Fund.

Following

an

analysis

and

discussion

of

the

foregoing,

and

the

factors

identified

below,

the

Board,

including

all

of

the

Independent

Trustees,

approved

the

IMS

Agreement.

Nature,

extent

and

quality

of

services

provided

by

the

Investment

Manager

The

Board

analyzed

various

reports

and

presentations

it

had

received

detailing

the

services

to

be

performed

by

the

Investment

Manager,

as

well

as

its

history,

expertise,

resources

and

relative

capabilities,

and

the

qualifications

of

its

personnel.

The

Board

specifically

considered

the

many

developments

during

recent

years

concerning

the

services

provided

by

the

Investment

Manager

to

the

Columbia

Funds.

Among

other

things,

the

Board

noted

the

organization

and

depth

of

the

equity

and

credit

research

departments.

The

Board

further

observed

the

enhancements

to

the

investment

risk

management

department's

processes,

systems

and

oversight,

over

the

past

several

years.

The

Board

also

took

into

account

the

broad

scope

of

services

provided

by

the

Investment

Manager

to

the

Fund,

including,

among

other

services,

investment,

risk

and

compliance

oversight.

The

Board

also

took

into

account

the

information

it

received

concerning

the

Investment

Manager's

ability

to

attract

and

retain

key

portfolio

management

personnel

and

that

it

has

sufficient

resources

to

provide

competitive

and

adequate

compensation

to

investment

personnel.

The

Board

also

considered

the

oversight

of

the

administrative

and

transfer

agency

services

to

be

provided

by

State

Street

Bank

and

Trust

Company

(SSBT).

The

Board

noted

its

review

at

the

meetings

in

July

and

August

of

2025

of

the

quality

of

services

to

be

provided

by

SSBT,

which

was

proposed

to

serve

as

the

transfer

agent,

custodian

and

administrator

for

the

Fund.

In

evaluating

the

quality

of

services

to

be

provided

under

the

IMS

Agreement,

the

Board

also

took

into

account

the

organization

and

strength

of

the

Fund's

and

its

service

providers'

compliance

programs.

The

Board

also

reviewed

the

financial

condition

of

the

Investment

Manager

and

its

affiliates

and

each

entity's

ability

to

carry

out

its

responsibilities

under

the

IMS

Agreement

and

the

Fund's

other

service

agreements.

In

addition,

the

Board

discussed

the

acceptability

of

the

terms

of

the

IMS

Agreement,

including

the

relatively

broad

scope

of

services

required

to

be

performed,

as

well

as

each

of

the

other

proposed

agreements

for

the

Fund.

The

Board

observed

that

the

proposed

agreements

were

substantively

identical

to

the

form

of

existing

agreements

with

respect

to

other

series

of

the

Trust

discussed

at

its

June

meeting

or,

in

the

case

of

those

agreements

with

SSBT,

discussed

at

its

meeting

on

August

26,

2025. The

Board

also

noted

the

wide

array

of

legal

and

compliance

services

provided

by

the

Investment

Manager

to

such

series.

After

reviewing

these

and

related

factors

(including

investment

performance

as

discussed

below),

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

nature,

extent

and

quality

of

the

services

to

be

provided

to

the

Fund

under

the

IMS

Agreement

supported

the

approval

of

the

IMS

Agreement.

Investment

performance

Because

the

Fund

had

not

yet

commenced

operations,

the

Board

did

not

have

actual investment

performance

of

the

new

ETF

to

compare

to

the

returns

of

a

group

of

comparable

funds.

The

Board

considered,

however,

the

performance

record

of

the

Predecessor

Fund,

which

would

be

reorganized

into

the

Fund.

The

Board

also

considered

the

Investment

Manager's

performance

and

reputation

generally,

the

Investment

Manager's

historical

responsiveness

to

Board

concerns

about

performance,

and

the

Investment

Manager's

willingness

to

take

steps

intended

to

improve

performance.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

performance

of

the

Investment

Manager,

in

light

of

other

considerations,

supported

the

approval

of

the

IMS

Agreement.

Comparative

fees,

costs

of

services

provided

and

the

profits

realized

by

the

Investment

Manager

and

its

affiliates

from

their

relationships

with

the

Fund

The

Board

reviewed

comparative

fees

and

the

costs

of

services

to

be

provided

under

the

IMS

Agreement.

The

Board

considered

the

proposed

unitary

fee

structure

to

be

utilized

by

the

Fund,

observing

that

many

of

the

competitors

of

the

Fund

have

adopted

similar

unitary

fee

structures.

The

Board

accorded

particular

weight

to

the

notion

that

a

primary

objective

of

the

proposed

level

of

fees

is

to

achieve

a

rational

pricing

model

applied

consistently

across

the

various

product

lines

in

the

Fund

family,

while

assuring

that

the

overall

fees

for

each

Columbia

Fund

(with

certain

exceptions)

are

generally

in

line

with

the

current

"pricing

philosophy"

such

that

Fund

total

expense

ratios,

in

general,

approximate

or

are

lower

than

the

median

expense

ratios

of

funds

in

the

same

Lipper

comparison

universe.

The

Board

considered

that

the

proposed

unitary

fee was

slightly

higher

than the

median

net

expense

ratio

of

peer

ETFs

and priced

competitively

to

comparable strategies.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

proposed

levels

of

management

fees

and

expenses

of

the

Fund,

in

light

of

other

considerations,

supported

the

approval

of

the

IMS

Agreement.

2026

The

Board

took

into

account

the

indirect

economic

benefits

flowing

to

the

Investment

Manager

or

its

affiliates

in

connection

with

managing

the

Columbia

Funds,

such

as

the

enhanced

ability

to

offer

various

other

financial

products

to

Ameriprise

Financial

customers

and

overall

reputational

advantages.

They

noted

that

the

fees

to

be

paid

by

the

Fund

should

permit

the

Investment

Manager

to

offer

competitive

compensation

to

its

personnel,

make

necessary

investments

in

its

business

and

earn

an

appropriate

profit.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

costs

of

services

to

be

provided

supported

the

approval

of

the

IMS

Agreement.

Economies

of

scale

The

Board

considered

that

the

proposed

IMS

Agreement

provides

for

a

unitary

fee

level

that

does

not

include

pre-

established

breakpoints,

and

management's

observation

that

ETF

fee

structures

often

do

not

include

breakpoints

due

to

the

more

volatile

nature

of

their

inflows/outflows.

Conclusion

The

Board

reviewed

all

of

the

above

considerations

in

reaching

its

decision

to

approve

the

IMS

Agreement.

In

reaching

its

conclusions,

no

single

factor

was

determinative.

On

September

5,

2025,

the

Board,

including

all

of

the

Independent

Trustees,

determined

that

fees

payable

under

the

IMS

Agreement

were

fair

and

reasonable

in

light

of

the

extent

and

quality

of

services

provided

and

approved

the

believed

including

all

of

Nature,

extent

and

quality

of

services

provided

by

the

Investment

Manager

The

Board

analyzed

various

reports

and

presentations

it

had

received

detailing

the

services

to

be

performed

by

the

Investment

Manager,

as

well

as

its

and

the

of

its

The

Board

specifically

considered

the

during

recent

years

concerning

the

services

provided

by

the

Investment

The

Board

also

took

into

account

the

information

it

received

concerning

the

Investment

Manager's

ability

to

attract

and

retain

key

portfolio

management

personnel

and

that

it

has

sufficient

resources

to

provide

competitive

and

adequate

compensation

to

investment

personnel.

The

Board

also

considered

the

oversight

of

the

administrative

and

transfer

agency

services

to

be

provided

by

State

Street

Bank

and

Trust

Company

(SSBT).

The

Board

noted

its

review

at

meetings

in

July

and

August

of

2025

of

the

quality

of

services

to

be

provided

by

SSBT,

which

was

proposed

to

serve

as

the

transfer

agent,

custodian

and

administrator

for

the

Fund.

In

evaluating

the

quality

of

services

to

be

provided

under

the

IMS

Agreement,

the

Board

also

took

into

account

the

organization

and

strength

of

the

Fund's

and

its

service

providers'

compliance

programs.

The

Board

also

reviewed

the

financial

condition

of

the

Investment

Manager

and

its

affiliates

and

each

entity's

ability

to

carry

out

its

responsibilities

under

the

IMS

Agreement

and

the

Fund's

other

service

agreements.

In

addition,

the

Board

discussed

the

acceptability

of

the

terms

of

the

IMS

Agreement,

including

the

relatively

broad

scope

of

services

required

to

be

performed,

as

well

as

each

of

the

other

proposed

agreements

and

plans

for

the

Fund.

The

Board

observed

that

the

proposed

agreements

and

plans

were

substantively

identical

to

the

form

of

existing

agreements

and

plans

with

respect

to

other

series

of

the

Trust

discussed

at

its

June

meeting

or,

in

the

case

of

those

agreements

with

SSBT,

discussed

at

its

on

August

Board

also

noted

the

wide

array

of

legal

and

compliance

services

provided

by

the

Investment

Manager

to

such

series.

After

reviewing

these

and

related

factors

(including

investment

performance

as

discussed

below),

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

nature,

extent

quality

of

the

services

to

under

the

approval

Investment

performance

Because

the

had

not

yet

commenced

operations,

the

Board

did

not

have

investment

performance

to

compare

to

the

returns

of

a

group

of

comparable

funds.

The

Board

considered

the

performance

of

the

Investment

Manager

for

a

fund

that

employs

substantially

similar

strategies

in

a

mutual

fund

format.

The

Board

also

considered

the

Investment

Manager's

performance

and

reputation

generally,

the

Investment

Manager's

historical

responsiveness

to

Board

concerns

about

performance,

and

the

Investment

Manager's

willingness

to

take

steps

intended

to

improve

performance.

After

reviewing

these

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

performance

of

the

comparative

fees

and

the

costs

of

to

under

The

considered

the

proposed

unitary

structure

to

be

utilized

by

the

Fund,

observing

that

many

of

the

competitors

of

the

Fund

have

adopted

similar

unitary

fee

structures.

The

Board

accorded

particular

weight

to

the

notion

that

a

primary

objective

of

the

proposed

level

of

fees

is

to

achieve

a

rational

pricing

model

applied

consistently

across

the

various

product

lines

in

the

Fund

family,

while

assuring

that

the

overall

fees

for

each

Columbia

Fund

(with

certain

exceptions)

are

generally

in

line

with

the

current

"pricing

philosophy"

such

that

Fund

total

expense

ratios,

in

general,

approximate

or

are

lower

than

the

median

expense

ratios

of

funds

in

the

same

Lipper

comparison

universe.

The

Board

considered

that

the

proposed

contractual unitary

fee

was

higher

than

the

median

net

expense

ratio

of

peer

ETFs.

The

Board

also

considered

that,

with

management's

proposed

expense

cap

reimbursement,

which

was

proposed

to

remain

in

place

through

July

31,

2027,

the

proposed

total

expense

ratio

for

the

Fund approximated

the

median

net

expense

ratio

of

the

Fund's

peer

ETFs

and

remained

competitive

with

similar

strategies.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

proposed

levels

of

management

fees

and

expenses

of

the

Fund,

in

light

of

considerations,

supported

the

The

Board

took

into

account

the

indirect

economic

benefits

flowing

to

the

Investment

Manager

or

its

affiliates

in

connection

with

managing

the

Columbia

Funds,

such

as

the

enhanced

ability

to

offer

various

other

financial

products

to

Ameriprise

Financial

customers

and

overall

reputational

advantages.

They

noted

that

the

fees

to

be

paid

by

the

Fund

should

permit

the

Investment

Manager

to

offer

competitive

compensation

to

its

personnel,

make

necessary

investments

in

its

business

and

earn

an

appropriate

profit.

After

these

and

factors,

the

concluded,

within

the

context

of

their

overall

conclusions,

that

the

costs

of

services

to

be

supported

the

approval

of

the

Economies

of

The

Board

considered

that

the

proposed

Agreement

provides

for

a

unitary

fee

level

that

does

not

include

pre-

established

breakpoints,

and

management's

observation

that

ETF

fee

structures

often

do

not

include

breakpoints

due

to

the

more

volatile

nature

of

their

The

Board

reviewed

all

of

the

above

considerations

in

reaching

its

decision

to

approve

the

In

reaching

that

should

be

considered

information

as

they,

their

legal

or

the

believed

reasonably

necessary

to

evaluate

and

Among

other

the

considered

included

the

following:

Information

on

and

and

Information

regarding

with

Following

an

analysis

and

discussion

of

the

foregoing,

and

the

factors

identified

below,

the

Board,

including

all

of

the

Independent

Trustees,

approved

the

IMS

Agreement.

Nature,

extent

and

quality

of

services

provided

by

the

Investment

Manager

The

Board

analyzed

various

reports

and

presentations

it

had

received

detailing

the

services

to

be

performed

by

the

Investment

Manager,

as

well

as

its

history,

expertise,

resources

and

relative

capabilities,

and

the

qualifications

of

its

personnel.

The

Board

specifically

considered

the

many

developments

during

recent

years

concerning

the

services

provided

by

the

Investment

Manager

to

the

Columbia

Funds.

Among

other

things,

the

Board

noted

the

organization

and

depth

of

the

equity

and

credit

research

departments.

The

Board

further

observed

the

enhancements

to

the

investment

risk

management

department's

processes,

systems

and

oversight,

over

the

past

several

years.

The

Board

also

took

into

account

the

broad

scope

of

services

provided

by

the

Investment

Manager

to

the

Fund,

including,

among

other

services,

investment,

risk

and

compliance

oversight.

The

Board

also

took

into

account

the

information

it

received

concerning

the

Investment

Manager's

ability

to

attract

and

retain

key

portfolio

management

personnel

and

that

it

has

sufficient

resources

to

provide

competitive

and

adequate

compensation

to

investment

personnel.

The

Board

also

considered

the

oversight

of

the

administrative

and

transfer

agency

services

to

be

provided

by

State

Street

Bank

and

Trust

Company

(SSBT).

The

Board

noted

its

review

at

meetings

in

July

and

August

of

2025

of

the

quality

of

services

to

be

provided

by

SSBT,

which

was

proposed

to

serve

as

the

transfer

agent,

custodian

and

administrator

for

the

Fund.

In

evaluating

the

quality

of

services

to

be

provided

under

the

IMS

Agreement,

the

Board

also

took

into

account

the

organization

and

strength

of

the

Fund's

and

its

service

providers'

compliance

programs.

The

Board

also

reviewed

the

financial

condition

of

the

Investment

Manager

and

its

affiliates

and

each

entity's

ability

to

carry

out

its

responsibilities

under

the

IMS

Agreement

and

the

Fund's

other

service

agreements.

In

addition,

the

Board

discussed

the

acceptability

of

the

terms

of

the

IMS

Agreement,

including

the

relatively

broad

scope

of

services

required

to

be

performed,

as

well

as

each

of

the

other

proposed

agreements

and

plans

for

the

Fund.

The

Board

observed

that

the

proposed

agreements

and

plans

were

substantively

identical

to

the

form

of

existing

agreements

and

plans

with

respect

to

other

series

of

the

Trust

discussed

at

its

June

meeting

or,

in

the

case

of

those

agreements

with

SSBT,

discussed

at

its

meeting

on

August

26,

2025. The

Board

also

noted

the

wide

array

of

legal

and

compliance

services

provided

by

the

Investment

Manager

to

such

series.

After

reviewing

these

and

related

factors

(including

investment

performance

as

discussed

below),

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

nature,

extent

and

quality

of

the

services

to

be

provided

to

the

Fund

under

the

IMS

Agreement

supported

the

approval

of

the

IMS

Agreement.

Investment

performance

Because

the

Fund

had

not

yet

commenced

operations,

the

Board

did

not

have

investment

performance

to

compare

to

the

returns

of

a

group

of

comparable

funds.

The

Board

considered

the

performance

of

the

Investment

Manager

for

a

fund

that

employs

substantially

similar

strategies

in

a

mutual

fund

format.

The

Board

also

considered

the

Investment

Manager's

performance

and

reputation

generally,

the

Investment

Manager's

historical

responsiveness

to

Board

concerns

about

performance,

and

the

Investment

Manager's

willingness

to

take

steps

intended

to

improve

performance.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

performance

of

the

Investment

Manager,

in

light

of

other

considerations,

supported

the

approval

of

the

IMS

Agreement.

Comparative

fees,

costs

of

services

provided

and

the

profits

realized

by

the

Investment

Manager

and

its

affiliates

from

their

relationships

with

the

Fund

The

Board

reviewed

comparative

fees

and

the

costs

of

services

to

be

provided

under

the

IMS

Agreement.

The

Board

considered

the

proposed

unitary

fee

structure

to

be

utilized

by

the

Fund,

observing

that

many

of

the

competitors

of

the

Fund

have

adopted

similar

unitary

fee

structures.

The

Board

accorded

particular

weight

to

the

notion

that

a

primary

objective

of

the

proposed

level

of

fees

is

to

achieve

a

rational

pricing

model

applied

consistently

across

the

various

product

lines

in

the

Fund

family,

while

assuring

that

the

overall

fees

for

each

Columbia

Fund

(with

certain

exceptions)

are

generally

in

line

with

the

current

"pricing

philosophy"

such

that

Fund

total

expense

ratios,

in

general,

approximate

or

are

lower

than

the

median

expense

ratios

of

funds

in

the

same

Lipper

comparison

universe.

The

Board

considered

that

the

proposed

unitary

fee

was

higher

than

the

median

net

expense

ratio

of

peer

ETFs.

The

Board

also

considered

that,

with

management's

proposed

expense

cap

reimbursement,

which

was

proposed

to

remain

in

place

through

July

31,

2027,

the

proposed

total

expense

ratio

for

the

Fund approximated

the

median

net

expense

ratio

of

the

Fund's

peer

ETFs

and

remained

competitive

with

similar

strategies.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

proposed

levels

of

fees

and

expenses

of

The

analyzed

various

reports

and

presentations

it

had

received

detailing

the

services

to

be

performed

by

the

Investment

Manager,

as

well

as

its

history,

expertise,

resources

and

relative

capabilities,

and

the

qualifications

of

its

personnel.

The

Board

specifically

considered

the

many

developments

during

recent

years

concerning

the

services

provided

by

the

Investment

Manager

to

the

Columbia

Funds.

Among

other

things,

the

Board

noted

the

organization

and

depth

of

departments.

The

Board

further

observed

the

enhancements

to

the

investment

risk

management

department's

processes,

systems

and

oversight,

over

the

past

several

years.

The

Board

also

took

into

account

the

broad

scope

of

services

provided

by

the

Investment

Manager

to

the

Fund,

including,

among

other

services,

investment,

risk

and

compliance

oversight.

The

Board

also

took

into

account

the

information

it

received

concerning

the

Investment

Manager's

ability

to

attract

and

retain

key

portfolio

management

personnel

and

that

it

has

sufficient

resources

to

provide

competitive

and

adequate

compensation

to

investment

personnel.

The

Board

also

considered

the

oversight

of

the

administrative

and

transfer

agency

services

to

be

provided

by

State

Street

Bank

and

Trust

Company

(SSBT).

The

Board

noted

its

review

at

meetings

in

July

and

August

of

2025

of

the

quality

of

services

to

be

provided

by

SSBT,

which

was

proposed

to

serve

as

the

transfer

agent,

custodian

and

administrator

for

the

Fund.

In

evaluating

the

quality

of

services

to

be

provided

under

the

IMS

Agreement,

the

Board

also

took

into

account

the

organization

and

strength

of

the

Fund's

and

its

service

providers'

compliance

programs.

The

Board

also

reviewed

the

financial

condition

of

the

Investment

Manager

and

its

affiliates

and

each

entity's

ability

to

carry

out

its

responsibilities

under

the

IMS

Agreement

and

the

Fund's

other

service

agreements.

In

addition,

the

Board

discussed

the

acceptability

of

the

terms

of

the

IMS

Agreement,

including

the

relatively

broad

scope

of

services

required

to

be

performed,

as

well

as

each

of

the

other

proposed

agreements

for

the

Fund.

The

Board

observed

that

the

proposed

agreements

were

substantively

identical

to

the

form

of

existing

agreements

with

respect

to

other

series

of

the

Trust

discussed

at

its

June

meeting

or,

in

the

case

of

those

agreements

with

SSBT,

discussed

at

its

meeting

on

August

26,

2025. The

Board

also

noted

the

wide

array

of

legal

and

compliance

services

provided

by

the

Investment

Manager

to

such

series.

After

reviewing

these

and

related

factors

(including

investment

performance

as

discussed

below),

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

nature,

extent

and

quality

of

the

services

to

be

provided

to

the

Fund

under

the

IMS

Agreement

supported

the

approval

of

the

IMS

Agreement.

Investment

performance

Because

the

Fund

had

not

yet

commenced

operations,

the

Board

did

not

have

actual investment

performance

of

the

new

ETF

to

compare

to

the

returns

of

a

group

of

comparable

funds.

The

Board

considered,

however,

the

performance

record

of

the

Predecessor

Fund,

which

would

be

reorganized

into

the

Fund.

The

Board

also

considered

the

Investment

Manager's

performance

and

reputation

generally,

the

Investment

Manager's

historical

responsiveness

to

Board

concerns

about

performance,

and

the

Investment

Manager's

willingness

to

take

steps

intended

to

improve

performance.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

performance

of

the

Investment

Manager,

in

light

of

other

considerations,

supported

the

approval

of

the

IMS

Agreement.

Comparative

fees,

costs

of

services

provided

and

the

profits

realized

by

the

Investment

Manager

and

its

affiliates

from

their

relationships

with

the

Fund

The

Board

reviewed

comparative

fees

and

the

costs

of

services

to

be

provided

under

the

IMS

Agreement.

The

Board

considered

the

proposed

unitary

fee

structure

to

be

utilized

by

the

Fund,

observing

that

many

of

the

competitors

of

the

Fund

have

adopted

similar

unitary

fee

structures.

The

Board

accorded

particular

weight

to

the

notion

that

a

primary

objective

of

the

proposed

level

of

fees

is

to

achieve

a

rational

pricing

model

applied

consistently

across

the

various

product

lines

in

the

Fund

family,

while

assuring

that

the

overall

fees

for

each

Columbia

Fund

(with

certain

exceptions)

are

generally

in

line

with

the

current

"pricing

philosophy"

such

that

Fund

total

expense

ratios,

in

general,

approximate

or

are

lower

than

the

median

expense

ratios

of

funds

in

the

same

Lipper

comparison

universe.

The

Board

considered

that

the

proposed

unitary

fee was

significantly

below the

median

net

expense

ratio

of

peer

ETFs

and

remained competitive

with similar strategies.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

proposed

levels

of

management

fees

and

expenses

of

the

Fund,

in

light

of

other

considerations,

supported

the

approval

of

the

IMS

Agreement.

The

Board

took

into

account

the

indirect

economic

benefits

flowing

to

the

Investment

Manager

or

its

in

connection

with

managing

the

Columbia

such

as

the

ability

to

to

and

They

noted

that

that

the

of

The

Board

considered

that

the

proposed

Agreement

provides

for

a

unitary

fee

level

that

does

not

include

pre-

established

breakpoints,

and

management's

observation

that

ETF

fee

structures

often

do

not

include

breakpoints

due

to

the

more

volatile

nature

of

their

inflows/outflows.

Conclusion

The

Board

reviewed

all

of

the

above

considerations

in

reaching

its

decision

to

approve

the

In

reaching

Under

the

investment

advice

and

other

services

to

the

and

other

funds

in

the

Columbia

Fund

family

(collectively,

the

Columbia

At

their

meeting

on

September

5,

2025,

the

Board

of

Trustees

(the

Board),

including

the

independent

Board

members

(the

Independent

of

Columbia

ETF

Trust

I

(the

unanimously

approved,

for

an

initial

two-year

term,

the

IMS

Agreement

with

the

Investment

Manager

with

respect

to

the

Fund,

a

series

of

the

Trust.

As

detailed

below,

the

Board

and

the

Board's

Contracts

Committee

and

Investment

Review

Committee

met

to

review

and

discuss,

both

among

themselves

and

with

the

management

team

of

the

Investment

Manager,

materials

provided

by

the

Investment

Manager

before

determining

to

approve

the

IMS

Agreement.

In

connection

with

their

deliberations

regarding

the

proposed

IMS

Agreement,

the

Committees

and

the

Board

evaluated

materials

requested

from

the

Investment

Manager

regarding

the

Fund

and

the

IMS

Agreement,

and

discussed

these

materials

with

representatives

of

the

Investment

Manager

at

the June

2025

Committee

and

full

meetings

(the

and

September

2025

and

full

meetings

(the

September

and,

together

with

the June

The

Independent

Trustees

also

considered

the

discussion

relating

to

the

renewal

of

advisory

agreements

for

other

series

of

the

Trust

at the

June

Meeting.

The

Committees

and

the

Board

also

consulted

with

the

Independent

Trustees'

independent

legal

counsel,

who

advised

on

various

matters

with

respect

to

the

Committees'

and

the

Board's

considerations

and

otherwise

assisted

the

Committees

and

the

Board

in

their

deliberations.

The

Board

considered

its

discussion

relating

to

the

renewal

of

advisory

agreements

with

respect

to

other

series

of

the

Trust

and,

in

that

connection,

the

discussion

by

independent

legal

counsel

of

the

factors

that

should

be

considered

in

determining

whether

to

approve

or

renew

an

investment

management

agreement.

The

Independent

Trustees

considered

such

information

as

they,

their

legal

counsel

or

the

Investment

Manager

believed

reasonably

necessary

to

evaluate

and

to

approve

the

IMS

Agreement.

Among

other

things,

the

information

and

factors

considered

included

the

following:

Information

on

the

Fund's

proposed

management

fees

and

anticipated

total

expenses;

Terms

of

the

IMS

Agreement;

Descriptions

of

various

services

performed

by

the

Investment

Manager

under

the

IMS

Agreement,

including

portfolio

management

and

portfolio

trading

practices;

Information

regarding

the

resources

of

the

Investment

Manager,

including

information

regarding

senior

management,

portfolio

managers

and

other

personnel;

and

Information

regarding

the

capabilities

of

the

Investment

Manager

with

respect

to

compliance

monitoring

services.

Following

an

analysis

and

discussion

of

the

foregoing,

and

the

factors

identified

below,

the

Board,

including

all

of

the

Independent

Trustees,

approved

the

IMS

Agreement.

Nature,

extent

and

quality

of

services

provided

by

the

Investment

Manager

The

Board

analyzed

various

reports

and

presentations

it

had

received

detailing

the

services

to

be

performed

by

the

Investment

Manager,

as

well

as

its

history,

expertise,

resources

and

relative

capabilities,

and

the

qualifications

of

its

personnel.

The

Board

specifically

considered

the

many

developments

during

recent

years

concerning

the

services

provided

by

the

Investment

Manager

to

the

Columbia

Funds.

Among

other

things,

the

Board

noted

the

organization

and

depth

of

the

equity

and

credit

research

departments.

The

Board

further

observed

the

enhancements

to

the

investment

risk

management

department's

processes,

systems

and

oversight,

over

the

past

several

years.

The

Board

also

took

into

account

the

broad

scope

of

services

provided

by

the

Investment

Manager

to

the

Fund,

including,

among

other

services,

investment,

risk

and

Approval

compliance

oversight.

The

Board

also

took

into

account

the

information

it

received

concerning

the

Investment

Manager's

ability

to

attract

and

retain

key

portfolio

management

personnel

and

that

it

has

sufficient

resources

to

provide

competitive

and

adequate

compensation

to

investment

personnel.

The

Board

also

considered

the

oversight

of

the

administrative

and

transfer

agency

services

to

be

provided

by

State

Street

Bank

and

Trust

Company

(SSBT).

The

Board

noted

its

review

at

meetings

in

July

and

August

of

2025

of

the

quality

of

services

to

be

provided

by

SSBT,

which

was

proposed

to

serve

as

the

transfer

agent,

custodian

and

administrator

for

the

Fund.

In

evaluating

the

quality

of

services

to

be

provided

under

the

IMS

Agreement,

the

Board

also

took

into

account

the

organization

and

strength

of

the

Fund's

and

its

service

providers'

compliance

programs.

The

Board

also

reviewed

the

financial

condition

of

the

Investment

Manager

and

its

affiliates

and

each

entity's

ability

to

carry

out

its

responsibilities

under

the

IMS

Agreement

and

the

Fund's

other

service

agreements.

In

addition,

the

Board

discussed

the

acceptability

of

the

terms

of

the

IMS

Agreement,

including

the

relatively

broad

scope

of

services

required

to

be

performed,

as

well

as

each

of

the

other

proposed

agreements

and

plans

for

the

Fund.

The

Board

observed

that

the

proposed

agreements

and

plans

were

substantively

identical

to

the

form

of

existing

agreements

and

plans

with

respect

to

other

series

of

the

Trust

discussed

at

its

June

meeting

or,

in

the

case

of

those

agreements

with

SSBT,

discussed

at

its

meeting

on

August

26,

2025. The

Board

also

noted

the

wide

array

of

legal

and

compliance

services

provided

by

the

Investment

Manager

to

such

series.

After

reviewing

these

and

related

factors

(including

investment

performance

as

discussed

below),

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

nature,

extent

and

quality

of

the

services

to

be

provided

to

the

Fund

under

the

IMS

Agreement

supported

the

approval

of

the

IMS

Agreement.

Investment

performance

Because

the

Fund

had

not

yet

commenced

operations,

the

Board

did

not

have

investment

performance

to

compare

to

the

returns

of

a

group

of

comparable

funds.

The

Board

also

considered

the

Investment

Manager's

performance

and

reputation

generally,

the

Investment

Manager's

historical

responsiveness

to

Board

concerns

about

performance,

and

the

Investment

Manager's

willingness

to

take

steps

intended

to

improve

performance.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

performance

of

the

Investment

Manager,

in

light

of

other

considerations,

supported

the

approval

of

the

IMS

Agreement.

Comparative

fees,

costs

of

services

provided

and

the

profits

realized

by

the

Investment

Manager

and

its

affiliates

from

their

relationships

with

the

Fund

The

Board

reviewed

comparative

fees

and

the

costs

of

services

to

be

provided

under

the

IMS

Agreement.

The

Board

considered

the

proposed

unitary

fee

structure

to

be

utilized

by

the

Fund,

observing

that

many

of

the

competitors

of

the

Fund

have

adopted

similar

unitary

fee

structures.

The

Board

accorded

particular

weight

to

the

notion

that

a

primary

objective

of

the

proposed

level

of

fees

is

to

achieve

a

rational

pricing

model

applied

consistently

across

the

various

product

lines

in

the

Fund

family,

while

assuring

that

the

overall

fees

for

each

Columbia

Fund

(with

certain

exceptions)

are

generally

in

line

with

the

current

"pricing

philosophy"

such

that

Fund

total

expense

ratios,

in

general,

approximate

or

are

lower

than

the

median

expense

ratios

of

funds

in

the

same

Lipper

comparison

universe.

The

Board

considered

that

the

proposed

unitary

fee

was

lower

than

the

median

net

expense

ratio

of

peer

ETFs

and priced

competitively

with

similar

strategies.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

proposed

levels

of

management

fees

and

expenses

of

the

Fund,

in

light

of

other

considerations,

supported

the

approval

of

the

IMS

Agreement.

The

Board

took

into

account

the

indirect

economic

benefits

flowing

to

the

Investment

Manager

or

its

affiliates

in

connection

with

managing

the

Columbia

Funds,

such

as

the

enhanced

ability

to

offer

various

other

financial

products

to

Ameriprise

Financial

customers

and

overall

reputational

advantages.

They

noted

that

the

fees

to

be

paid

by

the

Fund

should

permit

the

Approval

Investment

Manager

to

offer

competitive

compensation

to

its

personnel,

make

necessary

investments

in

its

business

and

earn

an

appropriate

profit.

After

reviewing

these

and

related

factors,

the

Board

concluded,

within

the

context

of

their

overall

conclusions,

that

the

costs

of

services

to

be

provided

supported

the

approval

of

the

IMS

Agreement.

Economies

of

scale

The

Board

considered

that

the

proposed

IMS

Agreement

provides

for

a

unitary

fee

level

that

does

not

include

pre-

established

breakpoints,

and

management's

observation

that

ETF

fee

structures

often

do

not

include

breakpoints

due

to

the

more

volatile

nature

of

their

inflows/outflows.

Conclusion

The

Board

reviewed

all

of

the

above

considerations

in

reaching

its

decision

to

approve

the

IMS

Agreement.

In

reaching

its

conclusions,

no

single

factor

was

determinative.

On

September

5,

2025,

the

Board,

including

all

of

the

Independent

Trustees,

determined

that

fees

payable

under

the

IMS

Agreement

were

fair

and

reasonable

in

light

of

the

extent

and

quality

of

services

provided

and

approved

the

Agreement.

Nature,

of

The

analyzed

by

as

personnel

and

that

it

The

Board

also

considered

the

oversight

of

the

administrative

and

transfer

agency

services

to

be

provided

by

State

Street

Bank

and

Trust

Company

(SSBT).

The

Board

noted

its

review

at

meetings

in

July

and

August

of

2025

of

the

quality

of

services

to

be

provided

by

SSBT,

which

was

In

evaluating

the

also

took

into

account

the

organization

and

strength

of

and

its

The

Board

also

reviewed

the

financial

and

each

entity's

ability

to

carry

out

its

responsibilities

under

In

addition,

the

scope

of

required

to

be

as

observing

that

of

accorded

the

is

to

**<u>Overview and Statement</u>**

Item 2 of Form N-CSR, the form used by registered management investment companies to file certified annual and semi-annual shareholder reports, requires a registered management investment company to disclose:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Whether it has adopted a code of ethics that applies to the investment company's principal executive
officer and senior financial officers and, if it has not adopted such a code of ethics, why it has not done so; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Any amendments to, or waivers from, the code of ethics relating to such officers.

The Board of the Columbia Funds ("Columbia Board") has adopted the following Code of Ethics for Principle Executive and Senior Financial Officers (the "Code"), which sets forth the ethical standards to which the Funds holds their principal executive officer and each of its senior financial officers.

This Code should be read and interpreted in conjunction with the *Overview and Implementation of Compliance Program Policy*.

**<u>Policy</u>**

The Board has adopted the Code in order to comply with applicable regulatory requirements as outlined below:

**I.** **Covered Officers/Purpose of the Code** 

This Code applies to the Fund's Principal Executive Officer, Principal Financial Officer, and Principal Accounting Officer or Controller (the "Covered Officers") for the purpose of promoting:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between
personal and professional relationships;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Full, fair, accurate, timely and understandable disclosure in reports and documents that the Fund files with, or
submits to, the SEC, and in other public communications made by the Fund;

*This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed. This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.* 

*Proprietary and Confidential* 

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Compliance with applicable laws and governmental rules and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The prompt internal reporting of violations of the Code to an appropriate person or persons identified in the
Code; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual or apparent conflicts of interest.

**II.** **Administration of the Code** 

The Board has designated an individual to be primarily responsible for the administration of the Code (the "Code Officer"). In the absence of the Code Officer, his or her designee shall serve as the Code Officer, but only on a temporary basis.

The Board has designated a person who meets the definition of a Chief Legal Officer (the "CLO") for purposes of the Sarbanes-Oxley Act of 2002 and the rules promulgated thereunder as the Fund's CLO. The CLO of the Fund shall assist the Fund's Code Officer in administration of this Code. The Code Officer, in consultation with the CLO, shall be responsible for applying this Code to specific situations (in consultation with Fund counsel, where appropriate) and has the authority to interpret this Code in any particular situation.

**III.** **Managing Conflicts of Interest** 

A "conflict of interest" occurs when a Covered Officer's personal interest interferes with the interests of, or his or her service to, the Fund. For example, a conflict of interest would arise if a Covered Officer, or a member of his or her family, receives improper personal benefits as a result of the Covered Officer's position with the Fund. Certain provisions in the 1940 Act and the rules and regulations thereunder and the Advisers Act and the rules and regulations thereunder govern certain conflicts of interest that arise out of the relationships between Covered Officers and the Fund. If such conflicts are addressed in conformity with applicable provisions of the 1940 Act and the Advisers Act, they will be deemed to have been handled ethically. The Fund's and its Adviser's compliance programs and procedures are designed to prevent, or identify and correct, violations of those provisions. This Code does not, and is not intended to, repeat or replace those programs and procedures, and conduct that is consistent with such programs and procedures falls outside of the parameters of this Code.

Although they do not typically present an opportunity for improper personal benefit, conflicts may arise from, or as a result of, the contractual relationships between the Fund and, as applicable, its Adviser (Columbia Management Investment Advisers, LLC ("CMIA") for the Columbia Funds, administrator, principal underwriter, pricing and bookkeeping agent and/or transfer agent (each, a "Primary Service Provider") of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Fund or for a Primary Service Provider, or for both), be involved in establishing policies and implementing decisions that will have different effects on the Primary Service Providers and the Fund. The participation of the

This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.* 

*Proprietary and Confidential*

------

Covered Officers in such activities is inherent in the contractual relationships between the Fund and the Primary Service Providers and is consistent with the performance by the Covered Officers of their duties as officers of the Fund. If such conflicts are addressed in conformity with applicable provisions of the 1940 Act and the Advisers Act, they will be deemed to have been handled ethically. In addition, it is recognized by the Board of the Funds that the Covered Officers also may be officers or employees of one or more other investment companies or organizations affiliated with the sponsor of the Funds covered by other similar codes and that the codes of ethics of those other investment companies or organizations will apply to the Covered Officers acting in such capacities for such other investment companies.

This Code covers general conflicts of interest and other issues applicable to the Funds under the Sarbanes-Oxley Act of 2002. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interests of the Funds. Certain examples of such conflicts of interest follow.

Each Covered Officer must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Not use his or her personal influence or personal relationships improperly to influence investment decisions or
financial reporting by the Fund whereby the Covered Officer, or a member of his or her family, would knowingly benefit personally to the detriment of the Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Not knowingly cause the Fund to take action, or fail to take action, for the individual personal benefit of the
Covered Officer, or a member of his or her family, rather than the benefit of the Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Not use material non-public knowledge of portfolio transactions made
or contemplated for the Fund to trade personally or cause others to trade personally in contemplation of the market effect of such transactions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Report at least annually (or more frequently, as appropriate) known affiliations or other relationships that may
give rise to conflicts of interest with respect to the Fund.

If a Covered Officer believes that he or she has a potential conflict of interest that is likely to materially compromise his or her objectivity or his or her ability to perform the duties of his or her role as a Covered Officer, including a potential conflict of interest that arises out of his or her responsibilities as an officer or employee of one or more Primary Service Providers or other funds, he or she should consult with the Code Officer, the CLO, the Fund's outside counsel, or counsel to the Independent Board Members, as appropriate.

Examples of potential conflicts of interest that may materially compromise objectivity or ability to perform the duties of a Covered Officer and which the Covered Officer should consider discussing with the Code Officer or other appropriate person include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Service as a director on the board of a public or private company or service as a public official;

This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.* 

*Proprietary and Confidential* 

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The receipt of a non-de minimus gift when the gift is in relation to
doing business directly or indirectly with the Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The receipt of entertainment from any company with which the Fund has current or prospective business dealings,
unless such entertainment is business-related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An ownership interest in, or any consulting or employment relationship with, any of the Fund's service
providers, other than the Primary Service Providers or any affiliated person thereof; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A direct or indirect material financial interest in commissions, transaction charges or spreads paid by the Fund
for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer's employment, such as compensation or equity ownership.

**IV.** **Disclosure and Compliance** 

It is the responsibility of each Covered Officer:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To familiarize himself or herself with the disclosure requirements generally applicable to the Fund, as well as
the business and financial operations of the Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To not knowingly misrepresent, and to not knowingly cause others to misrepresent, facts about the Fund to others,
whether within or outside the Fund, including to the Fund's Board, Legal Counsel, Independent Legal Counsel and auditors, and to governmental regulators and self-regulatory organizations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To the extent appropriate within his or her area of responsibility, consult with other officers and employees of
the Fund and the Primary Service Providers with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fund files with, or submits to, the SEC and in other public communications made by the
Fund; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To adhere to and, within his or her area of responsibility, promote compliance with the standards and
restrictions imposed by applicable laws, rules and regulations.

**V.** **Reporting and Accountability by Covered Officers** 

Each Covered Officer must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Upon adoption of the Code or becoming a Covered Officer, acknowledge in writing to the Fund's Board that he
or she has received, read and understands the Code, using the form attached as Appendix A hereto;

*This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed. This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.* 

*Proprietary and Confidential* 

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Annually thereafter acknowledge in writing to the Fund's Board that he or she has received and read the
Code and believes that he or she has complied with the requirements of the Code, using the form attached as Appendix B hereto;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Not retaliate against any employee or Covered Officer for reports of potential violations that are made in good
faith; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Notify the Code Officer promptly if he or she knows of any violation, or of conduct that reasonably could be
expected to be or result in a violation, of this Code. Failure to do so is a violation of this Code.

The Fund will follow the policy set forth below in investigating and enforcing this Code:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Code Officer will endeavor to take all appropriate action to investigate any potential violation reported to
him or her;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If, after such investigation, the Code Officer believes that no violation has occurred, the Code Officer will so
notify the person(s) reporting the potential violation, and no further action is required;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Any matter that the Code Officer, upon consultation with the CLO, believes is a violation will be reported by the
Code Officer or the CLO to the Fund's Audit Committee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Fund's Audit Committee will be responsible for granting waivers, as appropriate; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• This Code and any changes to or waivers of the Code will, to the extent required, be disclosed as provided by SEC
rules.

**VI.** **Other Policies** 

This Code shall be the sole code of ethics adopted by the Fund for the purposes of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms applicable to registered management investment companies thereunder. Insofar as other policies or procedures of the Fund or the Fund's Primary Service Providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superseded by this Code to the extent that they conflict with the provisions of this Code. The Fund's and its Adviser's and principal underwriter's codes of ethics under Rule 17j-1 under the 1940 Act and the more detailed policies and procedures of the Primary Service Providers as set forth in their respect Compliance Manuals are separate requirements applicable to the Covered Officers and are not part of this Code.

**VII.** **Disclosure of Amendments to the Code** 

Any amendments will, to the extent required, be disclosed in accordance with law.

*This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed. This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.*

**IX.** **Internal Use** 

The Code is intended solely for the internal use by the Fund and does not constitute an admission, by or on behalf of the Fund, as to any fact, circumstance, or legal conclusion.

**Reporting Requirements** 

Each Covered Officer must annually acknowledge in writing to the Fund's Board that he or she has received and read the Code and believes that he or she has complied with the requirements of the Code, using the form attached as Appendix II hereto.

The Code Officer or CLO shall report to the Fund's Audit Committee any violations of, or material issues arising under, this Code.

If the Audit Committee concurs that a violation has occurred, it will inform and make a recommendation to the Fund's Board, which will consider appropriate action, which may include review of, and appropriate modifications to: Applicable policies and procedures; Notification to the appropriate personnel of the Fund's Primary Service Providers or their boards; A recommendation to censure, suspend or dismiss the Covered Officer; or Referral of the matter to the appropriate authorities for civil action or criminal prosecution.

All material amendments to this Code must be in writing and approved or ratified by the Fund's Board, including a majority of the Independent Board Members.

The Code Officer, in conjunction with the CLO, shall be responsible for administration of this Code and for adopting procedures to ensure compliance with the requirements set forth herein.

Any issues that arise under this policy should be communicated to an employee's immediate supervisor, and appropriately escalated to AMC. Additionally, AMC will escalate any compliance issues relating to this Code to the Fund CCO and, if warranted, the appropriate Fund Board.
