Fair
value
measurements
The
Fund
categorizes
its
fair
value
measurements
according
to
a
three-level
hierarchy
that
maximizes
the
use
of
observable
inputs
and
minimizes
the
use
of
unobservable
inputs
by
prioritizing
that
the
most
observable
input
be
used
when
available.
Observable
inputs
are
those
that
market
participants
would
use
in
pricing
an
investment
based
on
market
data
obtained
from
sources
independent
of
the
reporting
entity.
Unobservable
inputs
are
those
that
reflect
the
Fund's
assumptions
about
the
information
market
participants
would
use
in
pricing
an
investment.
An
investment’s
level
within
the
fair
value
hierarchy
is
based
on
the
lowest
level
of
any
input
that
is
deemed
significant
to
the
asset's
or
liability’s
fair
value
measurement.
The
input
levels
are
not
necessarily
an
indication
of
the
risk
or
liquidity
associated
with
investments
at
that
level.
For
example,
certain
U.S.
government
securities
are
generally
high
quality
and
liquid,
however,
they
are
reflected
as
Level
2
because
the
inputs
used
to
determine
fair
value
may
not
always
be
quoted
prices
in
an
active
market.
Fair
value
inputs
are
summarized
in
the
three
broad
levels
listed
below:
Level
1
Valuations
based
on
quoted
prices
for
investments
in
active
markets
that
the
Fund
has
the
ability
to
access
at
the
measurement
date.
Valuation
adjustments
are
not
applied
to
Level
1
investments.
Level
2
Valuations
based
on
other
significant
observable
inputs
(including
quoted
prices
for
similar
securities,
interest
rates,
prepayment
speeds,
credit
risks,
etc.).
Level
3
Valuations
based
on
significant
unobservable
inputs
(including
the
Fund's
own
assumptions
and
judgment
in
determining
the
fair
value
of
investments).
Inputs
that
are
used
in
determining
fair
value
of
an
investment
may
include
price
information,
credit
data,
volatility
statistics,
and
other
factors.
These
inputs
can
be
either
observable
or
unobservable.
The
availability
of
observable
inputs
can
vary
between
investments,
and
is
affected
by
various
factors
such
as
the
type
of
investment,
and
the
volume
and
level
of
activity
for
that
investment
or
similar
investments
in
the
marketplace.
The
inputs
will
be
considered
by
the
Investment
Manager,
along
with
any
other
relevant
factors
in
the
calculation
of
an
investment’s
fair
value.
The
Fund
uses
prices
and
inputs
that
are
current
as
of
the
measurement
date,
which
may
include
periods
of
market
dislocations.
During
these
periods,
the
availability
of
prices
and
inputs
may
be
reduced
for
many
investments.
This
condition
could
cause
an
investment
to
be
reclassified
between
the
various
levels
within
the
hierarchy.
Investments
falling
into
the
Level
3
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
3
investments
due
to
lack
of
market
transparency
and
corroboration
to
support
these
quoted
prices.
Additionally,
valuation
models
may
be
used
as
the
pricing
source
for
any
remaining
investments
classified
as
Level
3.
These
models
may
rely
on
one
or
more
significant
unobservable
inputs
and/
or
significant
assumptions
by
the
Investment
Manager.
Inputs
used
in
valuations
may
include,
but
are
not
limited
to,
financial
statement
analysis,
capital
account
balances,
discount
rates
and
estimated
cash
flows,
and
comparable
company
data.
The
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
is
a
summary
of
the
inputs
used
to
value
the
Fund’s
investments
at
April
30,
2026:
See
the
Portfolio
of
Investments
for
all
investment
classifications
not
indicated
in
the
table. 
The
Fund’s
assets
assigned
to
the
Level
2
input
category
are
generally
valued
using
the
market
approach,
in
which
a
security’s
value
is
determined
through
reference
to
prices
and
information
from
market
transactions
for
similar
or
identical
assets.

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
zero
balance
may
reflect
an
amount
rounding
to
less
than
$0.01
or
0.01%.

(a)
Calculation
of
the
net
gain
(loss)
per
share
(both
realized
and
unrealized)
does
not
correlate
to
the
aggregate
realized
and
unrealized
gain
(loss)
presented
in
the
Statement
of
Operations
due
to
timing
of
subscriptions
and
redemptions
of
Fund
shares
in
relation
to
fluctuations
in
the
market
value
of
the
portfolio.
(b)
In
addition
to
the
fees
and
expenses
that
the
Fund
bears
directly,
the
Fund
indirectly
bears
a
pro
rata
share
of
the
fees
and
expenses
of
any
other
funds
in
which
it
invests.
Such
indirect
expenses
are
not
included
in
the
Fund's
reported
expense
ratios.
(c)
Ratios
include
less
than
0.01%
attributed
to
fees
outside
the
unitary
fee
(as
defined
in
Note
3).
(d)
The
ratio
includes
less
than
0.01%
attributed
to
overdraft
expense,
which
is
outside
the
unitary
fee
(as
defined
in
Note
3).
(e)
Total
net
expenses
include
the
impact
of
certain
fee
waivers/expense
reimbursements
made
by
the
Investment
Manager and
certain
of
its
affiliates,
if
applicable.

Fair
value
measurements
The
Fund
categorizes
its
fair
value
measurements
according
to
a
three-level
hierarchy
that
maximizes
the
use
of
observable
inputs
and
minimizes
the
use
of
unobservable
inputs
by
prioritizing
that
the
most
observable
input
be
used
when
available.
Observable
inputs
are
those
that
market
participants
would
use
in
pricing
an
investment
based
on
market
data
obtained
from
sources
independent
of
the
reporting
entity.
Unobservable
inputs
are
those
that
reflect
the
Fund's
assumptions
about
the
information
market
participants
would
use
in
pricing
an
investment.
An
investment’s
level
within
the
fair
value
hierarchy
is
based
on
the
lowest
level
of
any
input
that
is
deemed
significant
to
the
asset's
or
liability’s
fair
value
measurement.
The
input
levels
are
not
necessarily
an
indication
of
the
risk
or
liquidity
associated
with
investments
at
that
level.
For
example,
certain
U.S.
government
securities
are
generally
high
quality
and
liquid,
however,
they
are
reflected
as
Level
2
because
the
inputs
used
to
determine
fair
value
may
not
always
be
quoted
prices
in
an
active
market.
Fair
value
inputs
are
summarized
in
the
three
broad
levels
listed
below:
Level
1
Valuations
based
on
quoted
prices
for
investments
in
active
markets
that
the
Fund
has
the
ability
to
access
at
the
measurement
date.
Valuation
adjustments
are
not
applied
to
Level
1
investments.
Level
2
Valuations
based
on
other
significant
observable
inputs
(including
quoted
prices
for
similar
securities,
interest
rates,
prepayment
speeds,
credit
risks,
etc.).
Level
3
Valuations
based
on
significant
unobservable
inputs
(including
the
Fund's
own
assumptions
and
judgment
in
determining
the
fair
value
of
investments).
Inputs
that
are
used
in
determining
fair
value
of
an
investment
may
include
price
information,
credit
data,
volatility
statistics,
and
other
factors.
These
inputs
can
be
either
observable
or
unobservable.
The
availability
of
observable
inputs
can
vary
between
investments,
and
is
affected
by
various
factors
such
as
the
type
of
investment,
and
the
volume
and
level
of
activity
for
that
investment
or
similar
investments
in
the
marketplace.
The
inputs
will
be
considered
by
the
Investment
Manager,
along
with
any
other
relevant
factors
in
the
calculation
of
an
investment’s
fair
value.
The
Fund
uses
prices
and
inputs
that
are
current
as
of
the
measurement
date,
which
may
include
periods
of
market
dislocations.
During
these
periods,
the
availability
of
prices
and
inputs
may
be
reduced
for
many
investments.
This
condition
could
cause
an
investment
to
be
reclassified
between
the
various
levels
within
the
hierarchy.
Investments
falling
into
the
Level
3
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
3
investments
due
to
lack
of
market
transparency
and
corroboration
to
support
these
quoted
prices.
Additionally,
valuation
models
may
be
used
as
the
pricing
source
for
any
remaining
investments
classified
as
Level
3.
These
models
may
rely
on
one
or
more
significant
unobservable
inputs
and/
or
significant
assumptions
by
the
Investment
Manager.
Inputs
used
in
valuations
may
include,
but
are
not
limited
to,
financial
statement
analysis,
capital
account
balances,
discount
rates
and
estimated
cash
flows,
and
comparable
company
data.
The
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
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
zero
balance
may
reflect
an
amount
rounding
to
less
than
$0.01
or
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
2
because
the
inputs
used
to
determine
fair
value
may
not
always
be
quoted
prices
in
an
active
market.
Fair
value
inputs
are
summarized
in
the
three
broad
levels
listed
below:
Level
1
Valuations
based
on
quoted
prices
for
investments
in
active
markets
that
the
Fund
has
the
ability
to
access
at
the
measurement
date.
Valuation
adjustments
are
not
applied
to
Level
1
investments.
Level
2
Valuations
based
on
other
significant
observable
inputs
(including
quoted
prices
for
similar
securities,
interest
rates,
prepayment
speeds,
credit
risks,
etc.).
Level
3
Valuations
based
on
significant
unobservable
inputs
(including
the
Fund's
own
assumptions
and
judgment
in
determining
the
fair
value
of
investments).
Inputs
that
are
used
in
determining
fair
value
of
an
investment
may
include
price
information,
credit
data,
volatility
statistics,
and
other
factors.
These
inputs
can
be
either
observable
or
unobservable.
The
availability
of
observable
inputs
can
vary
between
investments,
and
is
affected
by
various
factors
such
as
the
type
of
investment,
and
the
volume
and
level
of
activity
for
that
investment
or
similar
investments
in
the
marketplace.
The
inputs
will
be
considered
by
the
Investment
Manager,
along
with
any
other
relevant
factors
in
the
calculation
of
an
investment’s
fair
value.
The
Fund
uses
prices
and
inputs
that
are
current
as
of
the
measurement
date,
which
may
include
periods
of
market
dislocations.
During
these
periods,
the
availability
of
prices
and
inputs
may
be
reduced
for
many
investments.
This
condition
could
cause
an
investment
to
be
reclassified
between
the
various
levels
within
the
hierarchy.
Investments
falling
into
the
Level
3
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
3
investments
due
to
lack
of
market
transparency
and
corroboration
to
support
these
quoted
prices.
Additionally,
valuation
models
may
be
used
as
the
pricing
source
for
any
remaining
investments
classified
as
Level
3.
These
models
may
rely
on
one
or
more
significant
unobservable
inputs
and/
or
significant
assumptions
by
the
Investment
Manager.
Inputs
used
in
valuations
may
include,
but
are
not
limited
to,
financial
statement
analysis,
capital
account
balances,
discount
rates
and
estimated
cash
flows,
and
comparable
company
data.
The
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
is
a
summary
of
the
inputs
used
to
value
the
Fund’s
investments
at
April
30,
2026:
See
the
Portfolio
of
Investments
for
all
investment
classifications
not
indicated
in
the
table. 
The
Fund’s
assets
assigned
to
the
Level
2
input
category
are
generally
valued
using
the
market
approach,
in
which
a
security’s
value
is
determined
through
reference
to
prices
and
information
from
market
transactions
for
similar
or
identical
assets.

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
zero
balance
may
reflect
an
amount
rounding
to
less
than
$0.01
or
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
2
because
the
inputs
used
to
determine
fair
value
may
not
always
be
quoted
prices
in
an
active
market.
Fair
value
inputs
are
summarized
in
the
three
broad
levels
listed
below:
Level
1
Valuations
based
on
quoted
prices
for
investments
in
active
markets
that
the
Fund
has
the
ability
to
access
at
the
measurement
date.
Valuation
adjustments
are
not
applied
to
Level
1
investments.
Level
2
Valuations
based
on
other
significant
observable
inputs
(including
quoted
prices
for
similar
securities,
interest
rates,
prepayment
speeds,
credit
risks,
etc.).
Level
3
Valuations
based
on
significant
unobservable
inputs
(including
the
Fund's
own
assumptions
and
judgment
in
determining
the
fair
value
of
investments).
Inputs
that
are
used
in
determining
fair
value
of
an
investment
may
include
price
information,
credit
data,
volatility
statistics,
and
other
factors.
These
inputs
can
be
either
observable
or
unobservable.
The
availability
of
observable
inputs
can
vary
between
investments,
and
is
affected
by
various
factors
such
as
the
type
of
investment,
and
the
volume
and
level
of
activity
for
that
investment
or
similar
investments
in
the
marketplace.
The
inputs
will
be
considered
by
the
Investment
Manager,
along
with
any
other
relevant
factors
in
the
calculation
of
an
investment’s
fair
value.
The
Fund
uses
prices
and
inputs
that
are
current
as
of
the
measurement
date,
which
may
include
periods
of
market
dislocations.
During
these
periods,
the
availability
of
prices
and
inputs
may
be
reduced
for
many
investments.
This
condition
could
cause
an
investment
to
be
reclassified
between
the
various
levels
within
the
hierarchy.
Investments
falling
into
the
Level
3
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
3
investments
due
to
lack
of
market
transparency
and
corroboration
to
support
these
quoted
prices.
Additionally,
valuation
models
may
be
used
as
the
pricing
source
for
any
remaining
investments
classified
as
Level
3.
These
models
may
rely
on
one
or
more
significant
unobservable
inputs
and/
or
significant
assumptions
by
the
Investment
Manager.
Inputs
used
in
valuations
may
include,
but
are
not
limited
to,
financial
statement
analysis,
capital
account
balances,
discount
rates
and
estimated
cash
flows,
and
comparable
company
data.
The
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

Non-income

(b)
Denotes
a
restricted
security,
which
is
subject
to
legal
or
contractual
restrictions
on
resale
under
federal
securities
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
April
30,
2026,
the
total
market
value
of
these
securities
amounted
to
$135,477,
which
represents
less
than
0.01%
of
total

assets.

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
zero
balance
may
reflect
an
amount
rounding
to
less
than
$0.01
or
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
2
because
the
inputs
used
to
determine
fair
value
may
not
always
be
quoted
prices
in
an
active
market.
Fair
value
inputs
are
summarized
in
the
three
broad
levels
listed
below:
Level
1
Valuations
based
on
quoted
prices
for
investments
in
active
markets
that
the
Fund
has
the
ability
to
access
at
the
measurement
date.
Valuation
adjustments
are
not
applied
to
Level
1
investments.
Level
2
Valuations
based
on
other
significant
observable
inputs
(including
quoted
prices
for
similar
securities,
interest
rates,
prepayment
speeds,
credit
risks,
etc.).
Level
3
Valuations
based
on
significant
unobservable
inputs
(including
the
Fund's
own
assumptions
and
judgment
in
determining
the
fair
value
of
investments).
Inputs
that
are
used
in
determining
fair
value
of
an
investment
may
include
price
information,
credit
data,
volatility
statistics,
and
other
factors.
These
inputs
can
be
either
observable
or
unobservable.
The
availability
of
observable
inputs
can
vary
between
investments,
and
is
affected
by
various
factors
such
as
the
type
of
investment,
and
the
volume
and
level
of
activity
for
that
investment
or
similar
investments
in
the
marketplace.
The
inputs
will
be
considered
by
the
Investment
Manager,
along
with
any
other
relevant
factors
in
the
calculation
of
an
investment’s
fair
value.
The
Fund
uses
prices
and
inputs
that
are
current
as
of
the
measurement
date,
which
may
include
periods
of
market
dislocations.
During
these
periods,
the
availability
of
prices
and
inputs
may
be
reduced
for
many
investments.
This
condition
could
cause
an
investment
to
be
reclassified
between
the
various
levels
within
the
hierarchy.
Investments
falling
into
the
Level
3
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
3
investments
due
to
lack
of
market
transparency
and
corroboration
to
support
these
quoted
prices.
Additionally,
valuation
models
may
be
used
as
the
pricing
source
for
any
remaining
investments
classified
as
Level
3.
These
models
may
rely
on
one
or
more
significant
unobservable
inputs
and/
or
significant
assumptions
by
the
Investment
Manager.
Inputs
used
in
valuations
may
include,
but
are
not
limited
to,
financial
statement
analysis,
capital
account
balances,
discount
rates
and
estimated
cash
flows,
and
comparable
company
data.

The
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
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
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
2
because
the
inputs
used
to
determine
fair
value
may
not
always
be
quoted
prices
in
an
active
market.
Fair
value
inputs
are
summarized
in
the
three
broad
levels
listed
below:
Level
1
Valuations
based
on
quoted
prices
for
investments
in
active
markets
that
the
Fund
has
the
ability
to
access
at
the
measurement
date.
Valuation
adjustments
are
not
applied
to
Level
1
investments.
Level
2
Valuations
based
on
other
significant
observable
inputs
(including
quoted
prices
for
similar
securities,
interest
rates,
prepayment
speeds,
credit
risks,
etc.).
Level
3
Valuations
based
on
significant
unobservable
inputs
(including
the
Fund's
own
assumptions
and
judgment
in
determining
the
fair
value
of
investments).
Inputs
that
are
used
in
determining
fair
value
of
an
investment
may
include
price
information,
credit
data,
volatility
statistics,
and
other
factors.
These
inputs
can
be
either
observable
or
unobservable.
The
availability
of
observable
inputs
can
vary
between
investments,
and
is
affected
by
various
factors
such
as
the
type
of
investment,
and
the
volume
and
level
of
activity
for
that
investment
or
similar
investments
in
the
marketplace.
The
inputs
will
be
considered
by
the
Investment
Manager,
along
with
any
other
relevant
factors
in
the
calculation
of
an
investment’s
fair
value.
The
Fund
uses
prices
and
inputs
that
are
current
as
of
the
measurement
date,
which
may
include
periods
of
market
dislocations.
During
these
periods,
the
availability
of
prices
and
inputs
may
be
reduced
for
many
investments.
This
condition
could
cause
an
investment
to
be
reclassified
between
the
various
levels
within
the
hierarchy.
Investments
falling
into
the
Level
3
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
3
investments
due
to
lack
of
market
transparency
and
corroboration
to
support
these
quoted
prices.
Additionally,
valuation
models
may
be
used
as
the
pricing
source
for
any
remaining
investments
classified
as
Level
3.
These
models
may
rely
on
one
or
more
significant
unobservable
inputs
and/
or
significant
assumptions
by
the
Investment
Manager.
Inputs
used
in
valuations
may
include,
but
are
not
limited
to,
financial
statement
analysis,
capital
account
balances,
discount
rates
and
estimated
cash
flows,
and
comparable
company
data.
The
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
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
zero
balance
may
reflect
an
amount
rounding
to
less
than
$0.01
or
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
2
because
the
inputs
used
to
determine
fair
value
may
not
always
be
quoted
prices
in
an
active
market.
Fair
value
inputs
are
summarized
in
the
three
broad
levels
listed
below:
Level
1
Valuations
based
on
quoted
prices
for
investments
in
active
markets
that
the
Fund
has
the
ability
to
access
at
the
measurement
date.
Valuation
adjustments
are
not
applied
to
Level
1
investments.
Level
2
Valuations
based
on
other
significant
observable
inputs
(including
quoted
prices
for
similar
securities,
interest
rates,
prepayment
speeds,
credit
risks,
etc.).
Level
3
Valuations
based
on
significant
unobservable
inputs
(including
the
Fund's
own
assumptions
and
judgment
in
determining
the
fair
value
of
investments).
Inputs
that
are
used
in
determining
fair
value
of
an
investment
may
include
price
information,
credit
data,
volatility
statistics,
and
other
factors.
These
inputs
can
be
either
observable
or
unobservable.
The
availability
of
observable
inputs
can
vary
between
investments,
and
is
affected
by
various
factors
such
as
the
type
of
investment,
and
the
volume
and
level
of
activity
for
that
investment
or
similar
investments
in
the
marketplace.
The
inputs
will
be
considered
by
the
Investment
Manager,
along
with
any
other
relevant
factors
in
the
calculation
of
an
investment’s
fair
value.
The
Fund
uses
prices
and
inputs
that
are
current
as
of
the
measurement
date,
which
may
include
periods
of
market
dislocations.
During
these
periods,
the
availability
of
prices
and
inputs
may
be
reduced
for
many
investments.
This
condition
could
cause
an
investment
to
be
reclassified
between
the
various
levels
within
the
hierarchy.
Investments
falling
into
the
Level
3
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
3
investments
due
to
lack
of
market
transparency
and
corroboration
to
support
these
quoted
prices.
Additionally,
valuation
models
may
be
used
as
the
pricing
source
for
any
remaining
investments
classified
as
Level
3.
These
models
may
rely
on
one
or
more
significant
unobservable
inputs
and/
or
significant
assumptions
by
the
Investment
Manager.
Inputs
used
in
valuations
may
include,
but
are
not
limited
to,
financial
statement
analysis,
capital
account
balances,
discount
rates
and
estimated
cash
flows,
and
comparable
company
data.
The
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
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
zero
balance
may
reflect
an
amount
rounding
to
less
than
$0.01
or
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
2
because
the
inputs
used
to
determine
fair
value
may
not
always
be
quoted
prices
in
an
active
market.
Fair
value
inputs
are
summarized
in
the
three
broad
levels
listed
below:
Level
1
Valuations
based
on
quoted
prices
for
investments
in
active
markets
that
the
Fund
has
the
ability
to
access
at
the
measurement
date.
Valuation
adjustments
are
not
applied
to
Level
1
investments.
Level
2
Valuations
based
on
other
significant
observable
inputs
(including
quoted
prices
for
similar
securities,
interest
rates,
prepayment
speeds,
credit
risks,
etc.).
Level
3
Valuations
based
on
significant
unobservable
inputs
(including
the
Fund's
own
assumptions
and
judgment
in
determining
the
fair
value
of
investments).
Inputs
that
are
used
in
determining
fair
value
of
an
investment
may
include
price
information,
credit
data,
volatility
statistics,
and
other
factors.
These
inputs
can
be
either
observable
or
unobservable.
The
availability
of
observable
inputs
can
vary
between
investments,
and
is
affected
by
various
factors
such
as
the
type
of
investment,
and
the
volume
and
level
of
activity
for
that
investment
or
similar
investments
in
the
marketplace.
The
inputs
will
be
considered
by
the
Investment
Manager,
along
with
any
other
Issuer
.

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

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
zero
balance
may
reflect
an
amount
rounding
to
less
than
$0.01
or
0.01%.

Calculation
of
the
net

(loss)
per

and
unrealized)
does
not
correlate
to
the
aggregate
realized
and
unrealized
gain
(loss)
presented
in
the
Statement
of
Operations
due
to
timing
of

I (the
Trust)
is
registered
under
the
Investment
Company
Act
of
1940,
as
amended
(the
1940
Act),
as
an
open-end
management
investment
company
organized
as
a
Massachusetts
business
trust.
Information
presented
in
these
financial
statements
pertains
to
the
following
series
of
the
Trust
(each,
a
Fund
and
collectively,
the
Funds):
Fund
Shares
The
Trust
may
issue
an
unlimited
number
of
shares
(without

The
market
prices
of
each
Fund's
shares
may
differ
to
some
degree
from
each
respective
Fund’s
net
asset
value
(NAV).
Unlike
conventional
mutual
funds,
each
Fund
issues
and
redeems
shares
on
a
continuous
basis,
at
NAV,
only
in
a
large
specified
number
of
shares,
each
called
a
“Creation

consists
of
50,000
shares,
except
for
Columbia

which
consists
of
25,000
shares. Creation

are
issued
and
redeemed
generally
in-kind
for
a
basket
of
securities
and/or
for
cash.
Investors
such
as
market
makers,
large
investors
and
institutions
who
wish
to
deal
in

must
have
entered

principal
underwriter
and
the

that

entered
into
such
an
agreement.
Authorized
Participants
may
purchase
or
redeem
Fund
shares
directly
from
the
Fund
only
in
Creation

The

for
which
investors
can
purchase

Note
2. Summary
of
significant
accounting
policies
Basis
of
preparation
Each
Fund
is
an
investment
company
that
applies
the
accounting
and
reporting
guidance
in
the
Financial
Accounting
Standards
Board
(FASB)
Accounting
Standards
Codification
Topic
946,
Financial
Services
-
Investment
Companies
(ASC
946).The
financial
statements
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
amounts
of
assets
and
liabilities,
the
disclosure
of
contingent
assets
and
liabilities
at
the
date
of
the
financial
statements
and
the
reported
amounts
of
income
and
expenses
during
the
reporting
period.
Actual
results
could
differ
from
those
estimates.
The
following
is
a
summary
of
significant
accounting
policies
followed
by
the
Funds
in
the
preparation
of
their
financial
statements.
Segment
reporting
The
intent
of
FASB
Accounting
Standards
Update
2023-07,
Segment
Reporting
(Topic
280)
-
Improvements
to
Reportable
Segment
Disclosures
is
to
enable
investors
to
better
understand
an
entity’s
overall
performance
and
to
assess
its
potential
future
cash
flows
through
improved
segment
disclosures.
The
chief
operating
decision
maker
(CODM)
for
the
Funds
is
Columbia
Management
Investment
Advisers,
LLC through
its
Investment
Oversight
Committee
and
Global
Executive
Group,
which
are
responsible
for
assessing
performance
and
making
decisions
about
resource
allocation.
The
CODM
has
determined
that
the
Funds
have
a
single
operating
segment
because
the
CODM
monitors
the
operating
results
of
the
Funds
as
a
whole
and
the
Funds'
long-term
strategic
asset
allocation
is
pre-determined
in
accordance
with
the
terms
of
each
Fund's
prospectus,
based
on
a
defined
investment
strategy
which
is
executed
by
the
Funds'
portfolio
managers

The
financial
information
provided
to
and
reviewed
by
the
CODM
is
consistent
with
that
presented
within
the
Funds'
financial
statements. 
Security
valuation
Equity
securities
listed
on
an
exchange
are
valued
at
the
closing
price
or
last
trade
price
on
their
primary
exchange
at
the
close
of
business
of
the
New
York
Stock
Exchange.
Securities
with
a
closing
price
not
readily
available
or
not
listed
on
any
exchange
are
valued
at
the
mean
between
the
closing
bid
and
ask
prices.
Listed
preferred
stocks
convertible
into
common
stocks
are
valued
using
an
evaluated
price
from
a
pricing
service.
Foreign
equity
securities
are
valued
based
on
the
closing
price
or
last
trade
price on
their
primary
exchange
at
the
close
of
business
of
the
New
York
Stock
Exchange.
If
any
foreign
equity
security
closing
prices
are
not
readily
available,
the
securities
are
valued
at
the
mean
of
the
latest
quoted
bid
and
ask
prices
on
such
exchanges
or
markets.
Foreign
currency
exchange
rates
are
generally
determined
at
the
close
of
London's
exchange
at
11:00
a.m.
Eastern
(U.S.)
time. 
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
data,
as
well
as
approved
independent
broker-dealer
quotes.
Debt
securities
for
which
quotations
are
not
readily
available
or
not
believed
to
be
reflective
of
market
value
may
also
be
valued
based
upon
a
bid
quote
from
an
approved
independent
broker-dealer.
Debt
securities
maturing
in
60
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
life.
Asset-backed
securities
for
which
quotations
are
readily
available
may
also
be
valued
based
upon
an
over-the-counter
or
exchange
bid
quote
from
an
approved
independent
broker-dealer.
Debt
securities
maturing
in
60
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.
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.
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
techniques.
In
addition,
investments
shall
be
disclosed
by
major
category.
This
information
is
disclosed
following
the Funds'
Portfolios
of
Investments. 
Foreign
currency
transactions
and
translations
The
values
of
all
assets
and
liabilities
denominated
in
foreign
currencies
are
generally
translated
into
U.S.
dollars
at
exchange
rates
determined
at
the
close
of
the
London
Stock
Exchange
on
any
given
day.
Net
realized
and
unrealized
gains
(losses)
on
foreign
currency
transactions
and
translations
include
gains
(losses)
arising
from
the
fluctuation
in
exchange
rates
between
trade
and
settlement
dates
on
securities
transactions,
gains
(losses)
arising
from
the
disposition
of
foreign

currency
and
currency
gains
(losses)
between
the
accrual
and
payment
dates
on
dividends,
interest
income
and
foreign
withholding
taxes.
For
financial
statement
purposes,
the
Funds
do
not
distinguish
that
portion
of
gains
(losses)
on
investments
which
is
due
to
changes
in
foreign
exchange
rates
from
that
which
is
due
to
changes
in
market
prices
of
the
investments.
Such
fluctuations
are
included
with
the
net
realized
and
unrealized
gains
(losses)
on
investments
in
the
Statement
of
Operations.
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
dollar
rolls
involve
the
risk
that
the
market
value
of
the
securities
the
Fund
is
obligated
to
repurchase
may
decline
below
the
repurchase
price,
or
that
the
counterparty
may
default
on
its
obligations.
All
cash
proceeds
will
be
invested
in
instruments
that
are
permissible
investments
for
the
Fund.
The
Fund
identifies
cash
or
liquid
securities
in
an
amount
equal
to
the
forward
purchase
price.
The
Fund
does
not
currently
enter
into
mortgage
dollar
rolls
that
are
accounted
for
as
financing
transactions.
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.

Income
recognition
Corporate
actions
and
dividend
income
are
generally
recorded
net
of
any
non-reclaimable
tax
withholdings,
on
the
ex-
dividend
date
or
upon
receipt
of
an
ex-dividend
notification
in
the
case
of
certain
foreign
securities.
Awards
from
class
action
litigation
are
recorded
as
a
reduction
of
cost
basis
if
the
Fund
still
owns
the
applicable
securities
on
the
payment
date.
If
the
Fund
no
longer
owns
the
applicable
securities
on
the
payment
date,
the
proceeds
are
recorded
as
realized
gains.
The Funds
may
receive
distributions
from
holdings
in
equity
securities,
business
development
companies
(BDCs),
exchange-
traded
funds
(ETFs),
limited
partnerships
(LPs),
other
regulated
investment
companies
(RICs),
and
real
estate
investment
trusts
(REITs),
which
report
information
as
to
the
tax
character
of
their
distributions
annually.
These
distributions
are
allocated
to
dividend
income,
capital
gain
and
return
of
capital
based
on
actual
information
reported.
Return
of
capital
is
recorded
as
a
reduction
of
the
cost
basis
of
securities
held.
If
the
Fund
no
longer
owns
the
applicable
securities,
return
of
capital
is
recorded
as
a
realized
gain.
With
respect
to
REITs,
to
the
extent
actual
information
has
not
yet
been
reported,
estimates
for
return
of
capital
are
made
by
Columbia
Management
Investment
Advisers,
LLC
(the
Investment
Manager),
a
wholly-owned
subsidiary
of
Ameriprise
Financial,
Inc.
(Ameriprise
Financial).
The
Investment
Manager's
estimates
are
subsequently
adjusted
when
the
actual
character
of
the
distributions
is
disclosed
by
the
REITs,
which
could
result
in
a
proportionate
change
in
return
of
capital
to
shareholders.
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.
Expenses
General
expenses
of
the Trust
are
allocated
to
the
Fund
and
other
funds
of
the Trust
based
upon
relative
net
assets
or
other
expense
allocation
methodologies
determined
by
the
nature
of
the
expense.
Expenses
directly
attributable
to
the
Fund
are
charged
to
the
Fund.
Determination
of
net
asset
value
The
net
asset
value
per
share
of a
Fund
is
computed
by
dividing
the
value
of
the
net
assets
of
each
Fund by
the
total
number
of
outstanding
shares
of
the
Fund,
rounded
to
the
nearest
cent,
at
the
close
of
regular
trading
(ordinarily
4:00
p.m.
Eastern
Time)
every
day
the
New
York
Stock
Exchange
is
open.
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
amended,
and
will
distribute
substantially
all
of
their
investment
company
taxable
income
and
net
capital
gain,
if
any,
for
their
tax
year,
and
as
such
will
not
be
subject
to
federal
income
taxes.
In
addition,
the
Funds
intend
to
distribute
in
each
calendar
year
substantially
all
of
their
ordinary
income,
capital
gain
net
income
and
certain
other
amounts,
if
any,
such
that
the
Funds
should
not
be
subject
to
federal
excise
tax.
Therefore,
no
federal
income
or
excise
tax
provision
is
recorded.
Foreign
taxes
The
Funds may
be
subject
to
foreign
taxes
on
income,
gains
on
investments
or
currency
repatriation,
a
portion
of
which
may
be
recoverable.
The
Fund
will
accrue
such
taxes
and
recoveries,
as
applicable,
based
upon
its
current
interpretation
of
tax
rules
and
regulations
that
exist
in
the
markets
in
which
it
invests.

Realized
gains
in
certain
countries
may
be
subject
to
foreign
taxes
at
the
Fund
level,
based
on
statutory
rates.
The
Fund
accrues
for
such
foreign
taxes
on
realized
and
unrealized
gains
at
the
appropriate
rate
for
each
jurisdiction,
as
applicable.
The
amount,
if
any,
is
disclosed
as
a
liability
in
the
Statement
of
Assets
and
Liabilities.
Distributions
to
shareholders
The
following
table
shows
the
anticipated
frequency
of
distributions
from
net
investment
income,
if
any,
for
each
Fund.
Net
realized
capital
gains,
if
any,
are
distributed
at
least
annually.
Income
distributions
and
capital
gain
distributions
are
determined
in
accordance
with
federal
income
tax
regulations,
which
may
differ
from
GAAP. 
Guarantees
and
indemnifications
Under
the
Trust's
organizational
documents
and,
in
some
cases,
by
contract,
its
officers
and
trustees
are
indemnified
against
certain
liabilities
arising
out
of
the
performance
of
their
duties
to
the
Trust
or
its
funds.
In
addition,
certain
of
the
Funds'
contracts
with
their
service
providers
contain
general
indemnification
clauses.
The
Funds'
maximum
exposure
under
these
arrangements
is
unknown
since
the
amount
of
any
future
claims
that
may
be
made
against
the
Funds
cannot
be
determined,
and
the
Funds
have
no
historical
basis
for
predicting
the
likelihood
of
any
such
claims.
Note
3. Investment
management
fees
Under
an
Investment
Management
Services
Agreement,
Columbia
Management
Investment
Advisers,
LLC
(the
Investment
Manager),
a
wholly-owned
subsidiary
of
Ameriprise
Financial,
Inc.
(Ameriprise
Financial),
determines
which
securities
will
be
purchased,
held
or
sold.
The
investment
management
fee
is
a
unitary
fee
paid
monthly
to
the
Investment
Manager
at
an
annual
rate
based
on
each
Fund’s
average
daily
net
assets.
In
return
for
this
fee,
the
Investment
Manager
pays
the
operating
costs
and
expenses
of
each
Fund
other
than
the
following
expenses
(which
will
be
paid
by
the
Fund):
taxes;
interest
incurred
on
borrowing
by
the
Fund,
if
any,
brokerage
fees
and
commissions;
interest
and
fee
expense
related
to
the
Fund’s
participation
in
inverse
floater
structures
and
any
other
portfolio
transaction
expenses;
infrequent
and/or
unusual
expenses,
including
without
limitation
litigation
expenses;
distribution
and/or
service
fees;
expenses
incurred
in
connection
with
lending
securities;
and
any
other
expenses
approved
by
the
Board
of
Trustees.
The
investment
management
fee
is
an
annual
fee
that
is
equal
to
a
percentage
of
each
Fund’s

net
assets

8. Fund
reorganization
for
Columbia
Research
Enhanced
Value
ETF
At
the
close
of
business
on March
13,
2026,
Columbia
Research
Enhanced
Value
ETF
(the
Fund) acquired
the
assets
and
assumed
the
identified
liabilities
of Columbia
Integrated
Large
Cap
Value
Fund
(the
Acquired
Fund),
a
series
of Columbia
Funds
Series
Trust
II.
The
reorganization
was
completed
after
the
Board
of
Trustees
of
the
Acquired
Fund
approved
a
plan
of
reorganization
at
a
meeting
held
in September
2025.
The
Investment
Manager
for
the
Fund
and
the
Acquired
Fund
believed
the
reorganization
was
in
the
best
interest
of
the
shareholders
of
the Acquired
Fund.
Reorganizing
the Acquired
Fund
into
the
Fund
may
offer
operational
advantages,
including
lower
overall
operating
expenses,
potentially
more
efficient
portfolio
management,
and
more
flexible
trading
of
shares
of
the Fund.
The
aggregate
net
assets
of
the
Fund
immediately
before
the
reorganization
were
$210,352,369
and
the
combined
net
assets
immediately
after
the
reorganization
were
$239,684,526.
The
reorganization
was
accomplished
by
a
tax-free
exchange
of 5,585,733
shares
of
the
Acquired
Fund
valued
at
$29,332,157
(including
$2,260,595
of
unrealized
appreciation/(depreciation)).
In
exchange
for
the
Acquired
Fund’s
shares,
the
Fund
issued 1,035,364
shares.
For
financial
reporting
purposes,
net
assets
received
and
shares
issued
by
the
Fund
were
recorded
at
fair
value;
however,
the
Acquired
Fund’s
cost
of
investments
was
carried
forward.
The
Fund’s
financial
statements
reflect
both
the
operations
of
the
Fund
for
the
period
prior
to
the
reorganization
and
the
combined
Fund
for
the
period
subsequent
to
the
reorganization.
Because
the
combined
investment
portfolios
have
been
managed
as
a
single
integrated
portfolio
since
the
reorganization
was
completed,
it
is
not
practicable
to
separate
the
amounts
of
revenue
and
earnings
of
the
Acquired
Fund
that
have
been
included
in
the
combined
Fund’s
Statement
of
Operations
since
the
reorganization
was
completed.
Assuming
the
reorganization
had
been
completed
on November
1,
2025,
the
Fund’s
pro-forma
results
of
operations
for
the
six
months
ended April
30,
2026
would
have
been
approximately:
Note
9. 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

Note
11. Information
regarding
pending
and
settled
legal
proceedings
Ameriprise
Financial
and
certain
of
its
affiliates
are
involved,
in
the
normal
course
of
business,
in
legal
proceedings
that
include
regulatory
inquiries,
arbitration
and
litigation
(including
class
actions)
concerning
matters
arising
in
connection
with
the
conduct
of
their
activities
as
part
of
a
diversified
financial
services
firm.
Ameriprise
Financial
believes
that
the
Funds
are
not
currently
the
subject
of,
and
that
neither
Ameriprise
Financial
nor
any
of
its
affiliates
are
the
subject
of,
any
pending
legal,
arbitration
or
regulatory
proceedings
that
are
likely
to
have
a
material
adverse
effect
on
the
Funds
or
the
ability
of
Ameriprise
Financial
or
its
affiliates
to
perform
under
their
contracts
with
the
Funds.
Ameriprise
Financial
is
required
to
make
quarterly
(10-Q),
annual
(10-K)
and,
as
necessary,
8-K
filings
with
the
Securities
and
Exchange
Commission
(SEC)
on
legal
and
regulatory
matters
that
relate
to
Ameriprise
Financial
and
its
affiliates.
Copies
of
these
filings
may
be
obtained
by
accessing
the
SEC
website
at
www.sec.gov.
There
can
be
no
assurance
that
these
matters,
or
the
adverse
publicity
associated
with
them,
will
not
result
in
increased
Fund
redemptions,
reduced
sale
of
Fund
shares
or
other
adverse
consequences
to
the
Funds.
Further,
although
we
believe these
proceedings
are
not
likely
to
have
a
material
adverse
effect
on
the
Funds
or
the
ability
of
Ameriprise
Financial
or
its
affiliates
to
perform
under
their
contracts
with
the
Funds,
these
proceedings
are
subject
to
uncertainties
and,
as
such,
it
is
inherently
difficult
to
determine
whether
any
loss
is
probable
or
even
reasonably
possible,
or
to
reasonably
estimate
the
amount
of
any
loss
that
may
result
from
such
matters.
An
adverse
outcome
in
one
or
more
of
these
proceedings
could
result
in
adverse
judgments,
settlements,
fines,
penalties
or
other
relief,
and
may
lead
to
further
claims,
examinations,
adverse
publicity
or
reputational
damage,
each
of
which
could
have
a
material
adverse
effect
on
the
consolidated
financial
condition
or
results
of
operations
or
financial
condition
of
Ameriprise
Financial
or
one
or
more
of
its
affiliates
that
provide
services
to
the
Funds.
