As

a

shareholder

of

a

Fund,

you

incur

ongoing

costs,

including

investment

management

fees.

The

following

example

is

intended

to

help

you

understand

your

ongoing

costs

(in

dollars

and

cents)

of

investing

in

a

fund

and

to

compare

these

costs

with

the

ongoing

costs

of

investing

in

other

funds.

The

examples

are

based

on

an

initial

investment

of

$1,000

invested

at

the

beginning

of

the

period

and

held

for

the

period

ended

September

30,

2019.

Actual

Expenses

The

information

under

each

column

in

the

table

below

entitled

“Actual”

provides

information

about

actual

account

values

and

actual

expenses.

You

may

use

the

information

in

these

columns,

together

with

the

amount

you

invested,

to

estimate

the

expenses

that

you

paid

over

the

period.

Simply

divide

your

account

value

by

$1,000

(for

example,

an

$8,600

account

value

divided

by

$1,000

=

8.6),

then

multiply

the

result

by

the

number

for

your

Fund

under

the

heading

entitled

“Expenses

paid

for

the

period”

to

estimate

the

expenses

you

paid

on

your

account

during

this

period.

Hypothetical

Example

For

Comparison

Purposes

The

information

under

each

column

in

the

table

entitled

“Hypothetical”

provides

information

about

hypothetical

account

values

and

hypothetical

expenses

based

on

each

Fund’s

actual

expense

ratio

and

an

assumed

rate

of

return

of

5%

per

year

before

expenses,

which

is

not

the

Fund’s

actual

return.

The

hypothetical

account

values

and

expenses

may

not

be

used

to

estimate

the

actual

ending

account

balance

or

expenses

you

paid

for

the

period.

You

may

use

this

information

to

compare

the

ongoing

costs

of

investing

in

your

Fund

and

other

funds.

To

do

so,

compare

this

5%

hypothetical

example

with

the

5%

hypothetical

examples

that

appear

in

the

shareholder

reports

of

the

other

funds.

Please

note

that

the

expenses

shown

in

the

table

are

meant

to

highlight

your

ongoing

costs

only

and

do

not

reflect

any

transactional

costs,

such

as

brokerage

commissions

paid

on

purchases

and

sales

of

Fund

shares.

Therefore,

the

ending

account

values

and

expenses

paid

for

the

period

in

the

table

is

useful

in

comparing

ongoing

Fund

costs

only

and

will

not

help

you

determine

the

relative

total

costs

of

owning

different

funds.

In

addition,

if

these

transactional

costs

were

included,

your

costs

would

have

been

higher.

Expenses

are

calculated

using

the

Fund’s

annualized

expense

ratio,

multiplied

by

the

average

account

value

over

the

period,

then

multiplied

by

the

number

of

days

in

the

Fund’s

most

recent

fiscal

half-year

and

divided

by

Had

the

Manager

on

secondary

markets

for

shares

of

a

Fund

and

that

Fund’s

net

value.

Net

asset

value,

or

“NAV”,

is

the

price

per

share

at

which

each

Fund

issues

and

redeems

shares.

It

is

calculated

in

accordance

with

the

standard

formula

for

valuing

fund

shares.

The

“Market

Price”

of

each

Fund

generally

is

determined

using

the

midpoint

between

the

highest

bid

and

the

lowest

offer

on

the

stock

exchange

on

which

the

shares

of

such

Fund

are

listed

for

trading,

as

of

the

time

that

the

Fund’s

NAV

is

calculated.

Each

Fund’s

Market

Price

may

be

at,

above

or

below

its

NAV.

The

of

will

of

will

fluctuate

in

are

the

between

the

NAV

and

Market

Price

of

a

Fund

on

a

given

day,

generally

at

the

time

NAV

is

calculated.

A

premium

is

the

amount

that

a

Fund

is

trading

above

the

reported

NAV,

expressed

as

a

A

discount

is

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.

Fair

Value

Measurements

(continued)

Investments

falling

into

the

Level

3

category

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

3

investments

due

to

lack

of

market

transparency

and

corroboration

to

support

these

quoted

prices.

Additionally,

valuation

models

may

be

used

as

the

pricing

source

for

any

remaining

investments

classified

as

Level

3.

These

models

may

rely

on

one

or

more

significant

unobservable

inputs

and/or

significant

assumptions

by

the

Investment

Manager.

Inputs

used

in

valuations

may

include,

but

are

not

limited

to,

financial

statement

analysis,

capital

account

balances,

discount

rates

and

estimated

cash

flows,

and

comparable

company

data.

Under

the

direction

of

the

Fund’s

Board

of

Trustees

(the

Board),

the

Investment

Manager’s

Valuation

Committee

(the

Committee)

is

responsible

for

overseeing

the

valuation

procedures

approved

by

the

Board.

The

Committee

consists

of

voting

and

non-voting

members

from

various

groups

within

the

Investment

Manager’s

organization,

including

operations

and

accounting,

trading

and

investments,

compliance,

risk

management

and

legal.

The

Committee

meets

at

least

monthly

to

review

and

approve

valuation

matters,

which

may

include

a

description

of

specific

valuation

determinations,

data

regarding

pricing

information

received

from

approved

pricing

vendors

and

brokers

and

the

results

of

Board-approved

valuation

control

policies

and

procedures

(the

Policies).

The

Policies

address,

among

other

things,

instances

when

market

quotations

are

or

are

not

readily

available,

including

recommendations

of

third

party

pricing

vendors

and

a

determination

of

appropriate

pricing

methodologies;

events

that

require

specific

valuation

determinations

and

assessment

of

fair

value

techniques;

securities

with

a

potential

for

stale

pricing,

including

those

that

are

illiquid,

restricted,

or

in

default;

and

the

effectiveness

of

third-party

pricing

vendors,

including

periodic

reviews

of

vendors.

The

Committee

meets

more

frequently,

as

needed,

to

discuss

additional

valuation

matters,

which

may

include

the

need

to

review

back-testing

results,

review

time-

sensitive

information

or

approve

related

valuation

actions.

The

Committee

reports

to

the

Board,

with

members

of

the

Committee

meeting

with

the

Board

at

each

of

its

regularly

scheduled

meetings

to

discuss

valuation

matters

and

actions

during

the

period,

similar

to

those

described

earlier.

For

investments

categorized

as

Level

3,

the

Committee

monitors

information

similar

to

that

described

above,

which

may

include:

(i)

data

specific

to

the

issuer

or

comparable

issuers,

(ii)

general

market

or

specific

sector

news

and

(iii)

quoted

prices

and

specific

or

similar

security

transactions.

The

Committee

considers

this

data

and

any

changes

from

prior

periods

in

order

to

assess

the

reasonableness

of

observable

and

unobservable

inputs,

any

assumptions

or

internal

models

used

to

value

those

securities

and

changes

in

fair

value.

This

data

is

also

used

to

corroborate,

when

available,

information

received

from

approved

pricing

vendors

and

brokers.

Various

factors

impact

the

frequency

of

monitoring

this

information

(which

may

occur

as

often

as

daily).

However,

the

Committee

may

determine

that

changes

to

inputs,

assumptions

and

models

are

not

required

as

a

result

of

the

monitoring

procedures

performed.

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

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

3

investments

due

to

lack

of

market

transparency

and

corroboration

to

support

these

quoted

prices.

Additionally,

valuation

models

may

be

used

as

the

pricing

source

for

any

remaining

investments

classified

as

Level

3.

These

models

may

rely

on

one

or

more

significant

unobservable

inputs

and/or

significant

assumptions

by

the

Investment

Manager.

Inputs

used

in

valuations

may

include,

but

are

not

limited

to,

financial

statement

analysis,

capital

account

balances,

discount

rates

and

estimated

cash

flows,

and

comparable

company

data.

Under

the

direction

of

the

Fund’s

Board

of

Trustees

(the

Board),

the

Investment

Manager’s

Valuation

Committee

(the

Committee)

is

responsible

for

overseeing

the

valuation

procedures

approved

by

the

Board.

The

Committee

consists

of

voting

and

non-voting

members

from

various

groups

within

the

Investment

Manager’s

organization,

including

operations

and

accounting,

trading

and

investments,

compliance,

risk

management

and

legal.

The

Committee

meets

at

least

monthly

to

review

and

approve

valuation

matters,

which

may

include

a

description

of

specific

valuation

determinations,

data

regarding

pricing

information

received

from

approved

pricing

vendors

and

brokers

and

the

results

of

Board-approved

valuation

control

policies

and

procedures

(the

Policies).

The

Policies

address,

among

other

things,

instances

when

market

quotations

are

or

are

not

readily

available,

including

recommendations

of

third

party

pricing

vendors

and

a

determination

of

appropriate

pricing

methodologies;

events

that

require

specific

valuation

determinations

and

assessment

of

fair

value

techniques;

securities

with

a

potential

for

stale

pricing,

including

those

that

are

illiquid,

restricted,

or

in

default;

and

the

effectiveness

of

third-party

pricing

vendors,

including

periodic

reviews

of

vendors.

The

Committee

meets

more

frequently,

as

needed,

to

discuss

additional

valuation

matters,

which

may

include

the

need

to

review

back-testing

results,

review

time-

sensitive

information

or

approve

related

valuation

actions.

The

Committee

reports

to

the

Board,

with

members

of

the

Committee

meeting

with

the

Board

at

each

of

its

regularly

scheduled

meetings

to

discuss

valuation

matters

and

actions

during

the

period,

similar

to

those

described

earlier.

Measurements

(continued)

For

investments

categorized

as

Level

3,

the

Committee

monitors

information

similar

to

that

described

above,

which

may

include:

(i)

data

specific

to

the

issuer

or

comparable

issuers,

(ii)

general

market

or

specific

sector

news

and

(iii)

quoted

prices

and

specific

or

similar

security

transactions.

The

Committee

considers

this

data

and

any

changes

from

prior

periods

in

order

to

assess

the

reasonableness

of

observable

and

unobservable

inputs,

any

assumptions

or

internal

models

used

to

value

those

securities

and

changes

in

fair

value.

This

data

is

also

used

to

corroborate,

when

available,

information

received

from

approved

pricing

vendors

and

brokers.

Various

factors

impact

the

frequency

of

monitoring

this

information

(which

may

occur

as

often

as

daily).

However,

the

Committee

may

determine

that

changes

to

inputs,

assumptions

and

models

are

not

required

as

a

result

of

the

monitoring

procedures

performed.

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

are

primarily

supported

by

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

those

investments.

However,

these

may

be

classified

as

Level

3

investments

due

to

lack

of

market

transparency

and

corroboration

to

support

these

quoted

prices.

Additionally,

valuation

models

may

be

used

as

the

pricing

source

for

any

remaining

investments

classified

as

Level

3.

These

models

may

rely

on

one

or

more

significant

unobservable

inputs

and/or

significant

assumptions

by

the

Investment

Manager.

Inputs

used

in

valuations

may

include,

but

are

not

limited

to,

financial

statement

analysis,

capital

account

balances,

discount

rates

and

estimated

cash

flows,

and

comparable

company

data.

Under

the

direction

of

the

Fund’s

Board

of

Trustees

(the

Board),

the

Investment

Manager’s

Valuation

Committee

(the

Committee)

is

responsible

for

overseeing

the

valuation

procedures

approved

by

the

Board.

The

Committee

consists

of

voting

and

non-voting

members

from

various

groups

within

the

Investment

Manager’s

organization,

including

operations

and

accounting,

trading

and

investments,

compliance,

risk

management

and

legal.

The

Committee

meets

at

least

monthly

to

review

and

approve

valuation

matters,

which

may

include

a

description

of

specific

valuation

determinations,

data

regarding

pricing

information

received

from

approved

pricing

vendors

and

brokers

and

the

results

of

Board-approved

valuation

control

policies

and

procedures

(the

Policies).

The

Policies

address,

among

other

things,

instances

when

market

quotations

are

or

are

not

readily

available,

including

recommendations

of

third

party

pricing

vendors

and

a

determination

of

appropriate

pricing

methodologies;

events

that

require

specific

valuation

determinations

and

assessment

of

fair

value

techniques;

securities

with

a

potential

for

stale

pricing,

including

those

that

are

illiquid,

restricted,

or

in

default;

and

the

effectiveness

of

third-party

pricing

vendors,

including

periodic

reviews

of

vendors.

The

Committee

meets

more

frequently,

as

needed,

to

discuss

additional

valuation

matters,

which

may

include

the

need

to

review

back-testing

results,

review

time-

sensitive

information

or

approve

related

valuation

actions.

The

Committee

reports

to

the

Board,

with

members

of

the

Committee

meeting

with

the

Board

at

each

of

its

regularly

scheduled

meetings

to

discuss

valuation

matters

and

actions

during

the

period,

similar

to

those

described

earlier.

For

investments

categorized

as

Level

3,

the

Committee

monitors

information

similar

to

that

described

above,

which

may

include:

(i)

data

specific

to

the

issuer

or

comparable

issuers,

(ii)

general

market

or

specific

sector

news

and

(iii)

quoted

prices

and

specific

or

similar

security

transactions.

The

Committee

considers

this

data

and

any

changes

from

prior

periods

in

order

to

assess

the

reasonableness

of

observable

and

unobservable

inputs,

any

assumptions

or

internal

models

used

to

value

those

securities

and

changes

in

fair

value.

This

data

is

also

used

to

corroborate,

when

available,

information

received

from

approved

pricing

vendors

and

brokers.

Various

factors

impact

the

frequency

of

monitoring

this

information

(which

may

occur

as

often

as

daily).

However,

the

Committee

may

determine

that

changes

to

inputs,

assumptions

and

models

are

not

required

as

a

result

of

the

monitoring

procedures

performed.

The

following

tables

are

intended

to

help

you

understand

each

Fund’s

financial

performance.

Per

amounts

are

calculated

based

on

average

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

at

net

asset

value

during

the

period

and

redemption

on

the

last

day

of

the

period.

Total

Return

at

is

calculated

assuming

an

initial

investment

made

at

the

market

price

at

the

beginning

of

the

period,

reinvestment

of

all

dividends

and

distributions

at

market

price

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.

The

price

used

to

calculate

Total

Return

at

is

based

on

the

midpoint

of

the

4:00

PM

Eastern

(U.S.)

bid/ask

spread

on

the

NYSE

and

does

not

represent

returns

an

were

traded

at

other

times.

Total

return

and

portfolio

turnover

are

not

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

may

be

higher.

All

accounts

and

have

been

eliminated

in

As

of

the

date

of

this

Columbia

virtually

all

has

historically

relied

on

a

tax

treaty

between

India

and

Mauritius

for

relief

from

certain

Indian

taxes.

The

enactment

of

general

anti-avoidance

rules

in

India,

the

signing

the

tax

treaty,

and

capital

gains

from

sales

of

Indian

shares

after

March

31,

2018

have

resulted

in

the

imposition

of

and

its

is

as

follows:

Fund

shares

The

market

prices

of

each

Fund’s

shares

may

differ

to

some

degree

from

the

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

Unit.”

A

Creation

Unit

consists

of

50,000

shares.

Creation

Units

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

Creation

Units

directly

with

a

Fund

must

have

entered

into

an

authorized

participant

agreement

(Authorized

with

the

Fund’s

principal

underwriter

and

the

that

has

entered

into

such

an

Authorized

participants

may

purchase

or

Fund

shares

directly

from

the

Fund

only

in

Creation

Units.

The

shares

are

also

listed

on

the

New

Exchange

for

which

investors

can

purchase

and

sell

shares

on

The

following

is

a

summary

of

significant

accounting

policies

followed

by

the

Funds

in

the

preparation

of

their

financial

statements.

Security

valuation

All

equity

securities

and

exchange-traded

funds

are

valued

at

the

close

of

business

of

the

New

York

Stock

Exchange.

Equity

securities

and

exchange-traded

funds

are

valued

at

the

last

quoted

sales

price

on

the

principal

exchange

or

market

on

which

they

trade,

except

for

securities

traded

on

the

NASDAQ

Stock

Market,

which

are

valued

at

the

NASDAQ

official

close

price.

Unlisted

securities

or

listed

securities

for

which

there

were

no

sales

during

the

day

are

valued

at

the

mean

of

the

latest

quoted

bid

and

ask

prices

on

such

exchanges

or

markets.

Debt

securities

generally

are

valued

by

pricing

services

approved

by

the

Board

of

Trustees

based

upon

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

cost

value,

unless

this

method

results

in

a

valuation

that

management

believes

does

not

approximate

market

value.

Foreign

equity

securities

are

valued

based

on

the

closing

price

on

the

foreign

exchange

in

which

such

securities

are

primarily

traded.

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.

Investments

in

open-end

investment

companies,

including

money

market

funds,

are

valued

at

their

latest

net

asset

value.

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

and

under

the

general

supervision

of

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’

Portfolio

of

Investments.

Foreign

currency

transactions

and

translation

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.

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

ex-dividend

notification

in

the

case

of

certain

foreign

securities.

Interest

income

is

recorded

on

an

accrual

basis.

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.

Expenses

General

expenses

of

the

Trust

are

allocated

to

the

Funds

based

upon

relative

net

assets

or

other

expense

allocation

methodologies

determined

by

the

nature

of

the

expense.

Expenses

directly

attributable

to

a

Fund

are

charged

to

that

Fund.

Determination

of

net

asset

value

The

NAV

per

share

of

each

Fund

is

computed

by

dividing

the

value

of

the

net

assets

of

a

Fund

by

the

total

number

of

outstanding

shares

of

that

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.

Each

Fund

intends

to

qualify

each

year

as

a

regulated

investment

company

under

Subchapter

M

of

the

Internal

Revenue

Code,

as

amended,

and

will

distribute

substantially

all

of

its

investment

company

taxable

income

and

net

capital

gain,

if

any,

for

its

tax

year,

and

as

such

will

not

be

subject

to

federal

income

taxes.

In

addition,

each

Fund

intends

to

distribute

in

each

calendar

year

substantially

all

of

its

ordinary

income,

capital

gain

net

income

and

certain

other

amounts,

if

any,

such

that

the

Fund

should

not

be

subject

to

federal

excise

tax.

Therefore,

no

federal

income

or

excise

tax

provisions

are

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

on

the

Statement

of

Assets

and

Liabilities.

Distributions

to

shareholders

The

Funds

declare

and

distribute

net

investment

income

annually.

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.

2019

Line

of

credit

Each

Fund

has

access

to

a

revolving

credit

facility

with

a

syndicate

of

banks

led

by

Citibank,

N.A.,

HSBC

Bank

USA,

N.A.

and

JPMorgan

Chase

Bank,

N.A.

whereby

the

Funds

may

borrow

for

the

temporary

funding

of

shareholder

redemptions

or

for

other

temporary

or

emergency

purposes.

The

credit

facility,

which

is

a

collective

agreement

between

the

Fund

and

certain

other

funds

managed

by

the

Investment

Manager

or

an

affiliated

investment

manager,

severally

and

not

jointly,

permits

collective

borrowings

up

to

$1

billion.

Interest

is

charged

to

each

participating

fund

based

on

its

borrowings

at

a

rate

equal

to

the

higher

of

(i)

the

federal

funds

effective

rate,

(ii)

the

one-month

LIBOR

rate

and

(iii)

the

overnight

bank

funding

rate,

plus

in

each

case,

1.00%.

Each

borrowing

under

the

credit

facility

matures

no

later

than

60

days

after

the

date

of

borrowing.

Each

Fund

also

pays

a

commitment

fee

equal

to

its

pro

rata

share

of

the

unused

amount

of

the

credit

facility

at

a

rate

of

0.15%

per

annum.

The

commitment

fee

is

included

in

other

expenses

in

the

Statement

of

Operations.

This

agreement

expires

annually

in

December

unless

extended

or

renewed.

During

the

six

months

ended

September

30,

2019,

the

Funds

had

no

borrowings.

Significant

risks

Concentration

risk

Each

Fund

concentrates

its

investments

in

a

particular

sector

or

a

group

of

sectors

to

approximately

the

same

extent

as

its

respective

underlying

index,

and

as

such,

may

be

adversely

affected

by

increased

price

volatility

of

securities

in

those

sectors,

and

may

be

more

susceptible

to

adverse

economic,

market,

political

or

regulatory

occurrences

affecting

those

sectors.

Consumer

concentration

risk

Because

Columbia

Emerging

Markets

Consumer

ETF

and

Columbia

India

Consumer

ETF

concentrate

their

investments

in

the

consumer

goods

and

consumer

services

sectors

(specifically

the

consumer

goods

and

consumer

services

sectors

of

India

for

the

Columbia

India

Consumer

ETF),

these

Funds

may

be

adversely

affected

by

increased

price

volatility

of

securities

in

those

sectors,

and

may

be

more

susceptible

to

adverse

economic,

market,

political

or

regulatory

occurrences

affecting

those

sectors.

The

success

of

consumer

goods

and

consumer

services

suppliers

and

retailers

is

tied

closely

to

the

performance

of

the

domestic

and

international

economy,

interest

rates,

currency

exchange

rates,

competition,

preferences,

and

consumer

confidence.

Country

and

regional

risk

Each

Fund

will

invest

in

specific

countries

or

geographic

regions

to

approximately

the

same

extent

as

its

underlying

index.

To

the

extent

that

a

Fund

invests

a

significant

portion

of

its

assets

in

a

particular

country

or

a

specific

geographic

region,

the

Fund

will

generally

have

more

exposure

to

that

country’s

or

region’s

economic

risks.

In

the

event

of

economic

or

political

turmoil

or

a

deterioration

of

diplomatic

relations

in

a

country

or

region

where

a

substantial

portion

of

a

Fund’s

assets

are

invested,

the

Fund

may

experience

increased

volatility

or

illiquidity

of

its

portfolio

holdings,

which

may

adversely

affect

that

Fund’s

performance.

Emerging

markets

risk

The

Funds

are

subject

to

emerging

markets

risk.

Investments

in

emerging

market

securities

are

likely

to

have

greater

exposure

to

risks

of

investing

in

foreign

investments

including

risks

associated

with

political,

regulatory,

economic,

social,

diplomatic,

and

other

conditions

or

events

(including,

for

example,

military

confrontations,

war

and

terrorism),

occurring

in

the

country

or

region.

In

addition,

emerging

market

countries

are

typically

less

developed

with

more

limited

trading

activity

than

more

developed

countries,

which

may

result

in

increased

liquidity

risk

and

other

risks.

Many

emerging

market

countries

are

heavily

dependent

on

international

trade

and

have

fewer

trading

partners,

which

may

make

them

more

sensitive

to

world

commodity

prices

and

economic

downturns

in

other

countries,

and

some

have

a

higher

risk

of

currency

devaluations.

Financial

concentration

risk

Columbia

EM

Core

ex-China

ETF

has

concentrated

investments

in

the

financials

sector.

Because

companies

in

the

financials

sector

are

subject

to

extensive

governmental

regulation,

which

may

adversely

affect

the

scope

of

their

activities,

the

prices

they

can

charge

and

the

amount

of

capital

they

must

maintain,

these

factors

may

adversely

affect

Fund

performance.

India

concentration

risk

Because

Columbia

India

Consumer

ETF,

invests

predominantly

in

Indian

securities,

its

NAV

will

be

much

more

sensitive

to

changes

in

economic,

political

and

other

factors

within

India

than

would

a

fund

that

invested

in

a

greater

variety

of

countries.

Special

risks

include,

among

others,

political

and

legal

uncertainty,

persistent

religious,

ethnic

and

border

disputes,

greater

government

control

over

the

economy,

currency

fluctuations

or

blockage

and

the

risk

of

nationalization

or

expropriation

of

assets.

Uncertainty

regarding

inflation

and

currency

exchange

rates,

fiscal

policy,

credit

ratings

and

the

possibility

that

future

harmful

political

actions

will

be

taken

by

the

Indian

government,

could

negatively

impact

the

Indian

economy

and

securities

markets,

and

thus

adversely

affect

the

Fund’s

performance.

India-Mauritius

tax

treaty

risk

Columbia

India

Consumer

ETF

and

its

respective

Subsidiary

historically

relied

on

a

tax

treaty

between

India

and

Mauritius

for

relief

from

certain

Indian

taxes.

India

and

Mauritius

agreed

to

an

amended

protocol

with

respect

to

gains

resulting

from

the

alienation

of

shares

in

Indian

companies

if

the

shares

were

acquired

by

the

Subsidiary

on

or

after

April

1,

2017.

Gains

realized

in

the

Subsidiary

resulting

from

the

alienation

of

Indian

shares

acquired

prior

to

April

1,

2017

continue

to

be

exempt

from

Indian

tax

under

the

India-Mauritius

tax

treaty.

Additionally,

India

has

enacted

General

anti-avoidance

rules

(GAAR),

which

seek

to

curb

tax

evasion

via

investments

through

foreign

tax

havens

and

other

avenues.

Any

assertion

that

the

Subsidiary

is

in

violation

of

GAAR

or

any

change

in

the

requirements

established

by

Mauritius

to

qualify

as

a

Mauritius

resident

could

result

in

the

imposition

by

India

of

various

taxes

on

Indian

securities

invested

in

by

the

Subsidiary

(and

indirectly

the

Fund).

The

imposition

of

taxes

on

the

Subsidiary

by

India

for

any

of

the

reasons

described

herein

would

result

in

higher

taxes

and

lower

returns

for

the

Fund

and

its

shareholders.

Non-diversification

risk

The

Funds

are

non-diversified

funds.

A

non-diversified

fund

is

permitted

to

invest

a

greater

percentage

of

its

total

assets

in

the

securities

of

fewer

issuers

than

a

diversified

fund.

This

increases

the

risk

that

a

change

in

the

value

of

any

one

investment

held

by

the

Fund

could

affect

the

overall

value

of

the

Fund

more

than

it

would

affect

that

of

a

diversified

fund

holding

a

greater

number

of

investments.

Accordingly,

the

Fund’s

value

will

likely

be

more

volatile

than

the

value

of

a

more

diversified

fund.

Passive

investment

risk

The

Funds

are

not

“actively”

managed

and

may

be

affected

by

a

general

decline

in

market

segments

related

to

their

underlying

index.

The

Funds

invest

in

securities

or

instruments

included

in,

or

believed

by

the

Investment

Manager

to

be

representative

of,

its

underlying

index,

regardless

of

their

investment

merits.

The

Funds

do

not

seek

temporary

defensive

positions

when

markets

decline

or

appear

overvalued.

The

decision

of

whether

to

remove

a

security

from

an

index

is

made

by

an

independent

index

provider

who

is

not

affiliated

with

the

Fund

or

the

Investment

Manager.

Technology

and

technology-related

investment

risk

Columbia

EM

Core

ex-China

ETF

may

be

more

susceptible

to

the

particular

risks

that

may

affect

companies

in

the

information

technology

sector,

as

well

as

other

technology-related

sectors

(collectively,

the

technology

sectors)

than

if

it

was

invested

in

a

wider

variety

of

companies

in

unrelated

sectors.

Companies

in

the

technology

sectors

are

subject

to

certain

risks,

including

the

risk

that

new

services,

equipment

or

technologies

will

not

be

accepted

by

consumers

and

businesses

or

will

become

rapidly

obsolete.

Performance

of

such

companies

may

be

affected

by

factors

including

obtaining

and

protecting

patents

(or

the

failure

to

do

so)

and

significant

competitive

pressures,

including

aggressive

pricing

of

their

products

or

services,

new

market

entrants,

competition

for

market

share

and

short

product

cycles

due

to

an

accelerated

rate

of

technological

developments.

Such

competitive

pressures

may

lead

to

limited

earnings

and/or

margins.

As

a

result,

Information

Ameriprise

of

Ameriprise

materials

were

revised

to

include

information

reflective

of

discussion

and

subsequent

requests

made

by

the

Contracts

Committee.

In

addition,

throughout

the

year,

the

Board

(or

its

committees)

regularly

meets

with

portfolio

management

teams

and

senior

management

personnel

and

reviews

information

prepared

by

Columbia

Threadneedle

addressing

the

services

Columbia

Threadneedle

provides

and

Fund

performance.

The

Board

also

accords

appropriate

weight

to

the

work,

deliberations

and

conclusions

of

the

various

committees,

such

as

the

Contracts

Committee,

the

Investment

Review

Committee,

the

Audit

Committee

and

the

Compliance

Committee

in

determining

whether

to

continue

the

IMS

Agreement.

The

Board,

at

its

June

17-19,

2019

in-person

Board

meeting

(the

June

Meeting),

considered

the

renewal

of

the

IMS

Agreement

for

an

additional

one-year

term.

At

the

June

Meeting,

Independent

Legal

Counsel

reviewed

with

the

Independent

Trustees

various

factors

relevant

to

the

Board's

consideration

of

investment

management

services

agreements

and

the

Board's

legal

responsibilities

related

to

such

consideration.

Following

an

analysis

and

discussion

of

the

factors

identified

below,

the

Board,

including

all

of

the

Independent

Trustees,

approved

the

renewal

of

the

IMS

Agreement.

Nature,

extent

and

quality

of

services

provided

by

Columbia

Threadneedle

The

Board

analyzed

various

reports

and

presentations

it

had

received

detailing

the

services

performed

by

Columbia

Threadneedle,

as

well

as

its

history,

reputation,

expertise,

resources

and

capabilities,

and

the

qualifications

of

its

personnel.

The

Board

specifically

considered

the

many

developments

during

recent

years

concerning

the

services

provided

by

Columbia

Threadneedle,

including,

in

particular,

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,

as

well

as

planned

2019

initiatives.

The

Board

also

took

into

account

the

broad

scope

of

services

provided

by

Columbia

Threadneedle

to

each

ETF,

including,

among

other

services,

investment,

risk

and

compliance

oversight.

The

Board

also

took

into

account

the

information

it

received

concerning

Columbia

Threadneedle'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.

In

connection

with

the

Board's

evaluation

of

the

overall

package

of

services

provided

by

Columbia

Threadneedle,

the

Board

also

considered

the

nature,

quality

and

range

of

administrative

oversight

services

provided

to

the

ETFs

by

Columbia

Threadneedle,

as

well

as

the

achievements

in

2018

in

the

performance

of

administrative

services,

and

noted

the

various

enhancements

anticipated

for

2019.

In

evaluating

the

quality

of

services

provided

under

the

IMS

Agreement,

the

Board

also

took

into

account

the

organization

and

strength

of

the

ETFs

and

Columbia

Threadneedle’s

compliance

program.

In

addition,

the

Board

reviewed

the

financial

condition

of

Columbia

Threadneedle

and

its

ability

to

carry

out

its

responsibilities

under

the

IMS

Agreement,

observing

the

financial

strength

of

Ameriprise

Financial,

with

its

relatively

strong

cash

position

and

solid

balance

sheet.

2019

The

Board

also

discussed

the

acceptability

of

the

terms

of

the

IMS

Agreement

(including

the

relatively

broad

scope

of

services

required

to

be

performed

by

Columbia

Threadneedle),

noting

that

no

material

changes

are

proposed

from

the

form

of

agreement

previously

approved.

They

also

noted

the

wide

array

of

legal

and

compliance

services

provided

to

the

ETFs

under

the

IMS

Agreement.

It

was

also

observed

that

the

services

being

performed

under

the

IMS

Agreement

were

of

a

reasonably

high

quality.

Based

on

the

foregoing,

and

based

on

other

information

received

(both

oral

and

written,

including

the

information

on

investment

performance

referenced

below)

and

other

considerations,

the

Board

concluded

that

Columbia

Threadneedle

is

in

a

position

to

continue

to

provide

a

high

quality

and

level

of

services

to

the

ETFs.

Investment

performance

For

purposes

of

evaluating

the

nature,

extent

and

quality

of

services

provided

under

the

IMS

Agreement,

the

Board

carefully

reviewed

the

investment

performance

of

each

ETF.

In

this

regard,

the

Board

considered

detailed

reports

providing

the

results

of

analyses

performed

by

an

independent

organization

showing,

for

various

periods

(including

since

manager

inception),

the

performance

of

each

ETF

(particularly

relative

to

the

index

of

which

the

ETF

seeks

to

replicate

performance)

and

its

net

assets.

The

Board

observed

the

passive

nature

of

the

ETFs

and

reviewed

index

tracking

error

data

for

each

of

the

ETFs.

The

Board

observed

that

each

ETF’s

performance

met

expectations.

Comparative

fees,

costs

of

services

provided

and

the

profits

realized

by

Columbia

Threadneedle

from

its

relationship

with

the

ETFs

The

Board

reviewed

comparative

fees

and

the

costs

of

services

provided

under

the

IMS

Agreement.

In

considering

the

proposed

level

of

fees

under

the

IMS

Agreement,

the

Board

accorded

particular

weight

to

the

unified/all-inclusive

fee

structure

utilized

by

each

ETF.

In

this

regard,

they

observed

that

many

of

the

competitors

of

the

ETFs

have

adopted

similar

unified/all-inclusive

fee

structures.

The

Trustees

also

considered

the

proposed

significant

reduction

in

the

contractual

investment

management

services

fee

for

Columbia

EM

Core

ex-China

ETF.

More

generally,

the

Board

accorded

particular

weight

to

the

notion

that

the

primary

objective

of

the

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

Fund

(with

certain

defined

exceptions)

are

generally

in

line

with

the

"pricing

philosophy"

currently

in

effect

(i.e.,

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

observed

that

each

of

the

ETFs’

unified

fee

rates

was

approximately

equal

to

or

lower

than

the

median

expenses

paid

by

funds

in

each

ETF’s

comparative

peer

universe.

Based

on

its

review,

the

Board

concluded

that

each

ETF’s

investment

management

services

fee

was

fair

and

reasonable

in

light

of

the

extent

and

quality

of

services

that

each

ETF

receives.

The

Board

also

considered

the

profitability

of

Columbia

Threadneedle

in

connection

with

providing

investment

management

services

to

each

ETF.

In

this

regard,

the

Independent

Trustees

referred

to

their

detailed

analysis

of

the

Profitability

Report,

discussing

the

profitability

to

Columbia

Threadneedle

and

Ameriprise

Financial

from

managing

the

Funds,

including

the

ETFs.

The

Board

considered

that

in

2018

the

Board

had

concluded

that

2017

profitability

was

reasonable

and

that

the

2019

information

shows

that

the

profitability

generated

by

Columbia

Threadneedle

in

2018

only

slightly

increased

from

2017

levels.

The

Board

also

noted

the

report

from

the

Board's

independent

fee

consultant,

JDL

Consultants,

LLC,

and

its

conclusion

that

2018

Columbia

Threadneedle

profitability

relative

to

industry

competitors

was

reasonable.

It

also

took

into

account

the

indirect

economic

benefits

flowing

to

Columbia

Threadneedle

or

its

affiliates

in

connection

with

managing

the

Funds,

including

the

ETFs,

such

as

the

enhanced

ability

to

offer

various

other

financial

products

to

Ameriprise

Financial

customers,

soft

dollar

benefits

and

overall

reputational

advantages.

The

Board

noted

that

the

fees

paid

by

the

ETFs

should

permit

the

Investment

Manager

to

offer

competitive

compensation

to

its

personnel,

make

necessary

investments

in

its

business

and

earn

an

appropriate

profit.

The

Board

concluded

that

profitability

levels

were

reasonable.

Economies

of

scale

to

be

realized

The

Board

also

considered

the

economies

of

scale

that

might

be

realized

by

the

ETFs

as

their

net

asset

levels

grow

and

took

note

of

the

extent

to

which

each

ETF’s

shareholders

might

also

benefit

from

such

growth.

The

Board

considered

that

the

IMS

Agreement

provides

for

a

unified

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.

Based

on

the

foregoing,

the

Board,

including

all

of

the

Independent

Trustees,

concluded

that

the

investment

management

services

fees

were

fair

and

reasonable

in

light

of

the

extent

and

quality

of

services

provided.

In

reaching

this

conclusion,

no

single

factor

was

determinative.

On

June

19,

2019,

the

Board,

including

all

of

the

Independent

Trustees,

approved

the

renewal

of

the

IMS

Agreement.
