which

may

include

money

market

funds

and

other

registered

open-end

investment

companies.

Investments

in

registered

open

end

investment

companies,

other

than

exchange-traded

funds,

are

valued

at

the

respective

fund’s

closing

net

asset

value

per

share

on

the

day

of

valuation.

The

Funds

value

securities,

including

exchange-traded

fund,

for

which

market

quotations

are

readily

available

at

fair

value,

which

is

determined

using

the

last

reported

sale

price.

If

no

sales

are

reported,

as

is

regularly

the

case

for

some

securities

traded

over-the-counter,

securities

are

valued

using

the

last

reported

bid

price

or

an

evaluated

bid

price

provided

by

a

pricing

service.

Pricing

services

use

modeling

techniques

that

incorporate

security

characteristics

such

as

current

quotations

by

broker/dealers,

coupon,

maturity,

quality,

type

of

issue,

trading

characteristics,

other

yield

and

risk

factors,

and

other

market

conditions

to

determine

an

evaluated

bid

price,

or

in

the

case

of

certain

credit

default

swaps,

a

mean

price

provided

by

a

pricing

service.

When

reliable

market

quotations

are

not

considered

to

be

readily

available,

which

may

be

the

case,

for

example,

with

respect

to

restricted

securities,

certain

debt

securities,

preferred

stocks

and

foreign

securities,

the

investments

are

valued

at

their

fair

value

as

determined

in

good

faith

by

Principal

Global

Investors,

LLC

(the

“Manager”)

under

procedures

established

and

periodically

reviewed

by

the

Fund’s

Board

of

Directors.

The

value

of

foreign

securities

used

in

computing

the

net

asset

value

per

share

is

generally

determined

as

of

the

close

of

the

foreign

exchange

where

the

security

is

principally

traded.

Events

that

occur

after

the

close

of

the

applicable

foreign

market

or

exchange

but

prior

to

the

calculation

of

the

Funds’

net

asset

value

are

reflected

in

the

Funds’

net

asset

value

and

these

securities

are

valued

at

fair

value.

Many

factors,

provided

by

independent

pricing

services,

are

reviewed

in

the

course

of

making

a

good

faith

determination

of

a

security’s

fair

value,

including,

but

not

limited

to,

price

movements

in

American

Depository

Receipts

(“ADRs”),

futures

contracts,

industry

indices,

general

indices,

and

foreign

currencies.

To

the

extent

the

Funds

invests

in

foreign

securities

listed

on

foreign

exchanges

which

trade

on

days

on

which

the

Funds

do

not

determine

net

asset

value,

for

example

weekends

and

other

customary

national

U.S.

holidays,

the

Funds

net

asset

value

could

be

significantly

affected

on

days

when

shareholders

cannot

purchase

or

redeem

shares.

Certain

securities

issued

by

companies

in

emerging

market

countries

may

have

more

than

one

quoted

valuation

at

any

given

point

in

time,

sometimes

referred

to

as

a

"local"

price

and

a

"premium"

price.

The

premium

price

is

often

a

negotiated

price,

which

may

not

consistently

represent

a

price

at

which

a

specific

transaction

can

be

affected.

It

is

the

policy

of

the

Fund

to

value

such

securities

at

prices

at

which

it

is

expected

those

shares

may

be

sold,

and

the

Manager

or

any

Sub-Advisor

is

authorized

to

make

such

determinations

subject

to

such

oversight

by

the

Board

as

may

occasionally

be

necessary.

Fair

value

is

defined

as

the

price

that

the

Funds

would

receive

upon

selling

a

security

or

transferring

a

liability

in

a

timely

transaction

to

an

independent

buyer

in

the

principal

or

most

advantageous

market

of

the

security

at

the

measurement

date.

In

determining

fair

value,

the

Funds

may

use

one

or

more

of

the

following

approaches:

market,

income

and/or

cost.

A

hierarchy

for

inputs

is

used

in

measuring

fair

value

that

maximizes

the

use

of

observable

inputs

and

minimizes

the

use

of

unobservable

inputs

by

requiring

that

the

most

observable

inputs

be

used

when

available.

Observable

inputs

are

inputs

that

reflect

the

assumptions

market

participants

would

use

in

pricing

the

asset

or

liability

developed

based

on

market

data

obtained

from

sources

independent

of

the

Fund.

Unobservable

inputs

are

inputs

that

reflect

the

Fund’s

own

estimates

about

the

estimates

market

participants

would

use

in

pricing

the

asset

or

liability

developed

based

on

the

best

information

available

in

the

circumstances.

September

(unaudited)

The

three-tier

hierarchy

of

inputs

is

summarized

in

the

three

broad

levels

listed

below.

Level

1

–

Quoted

prices

are

available

in

active

markets

for

identical

securities

as

of

the

reporting

date.

Investments

which

are

generally

included

in

this

category

include

listed

equities

and

exchange-traded

derivatives.

Level

2

–

Other

significant

observable

inputs

(including

quoted

prices

for

similar

investments,

interest

rates,

prepayment

speeds,

credit

risk,

etc.)

Investments

which

are

generally

included

in

this

category

include

certain

foreign

equities,

corporate

bonds,

municipal

bonds,

OTC

derivatives,

exchange

cleared

derivatives,

senior

floating

rate

interests,

repurchase

agreements,

and

US

Government

and

Government

Agency

Obligations.

Level

3

–

Significant

unobservable

inputs

(including

the

Funds’

assumptions

in

determining

the

fair

value

of

investments).

Investments

which

are

generally

included

in

this

category

include

certain

common

stocks,

convertible

preferred

stocks,

corporate

bonds,

preferred

stocks,

or

senior

floating

rate

interests.

The

availability

of

observable

inputs

can

vary

from

security

to

security

and

is

affected

by

a

wide

variety

of

factors,

including,

for

example,

the

type

of

security,

whether

the

security

is

new

and

not

yet

established

in

the

market

place,

and

other

characteristics

particular

to

the

transaction.

To

the

extent

that

valuation

is

based

on

models

or

inputs

that

are

less

observable

or

unobservable

in

the

market,

the

determination

of

fair

value

requires

more

judgment.

Accordingly,

the

degree

of

judgment

exercised

by

the

Funds

in

determining

fair

value

is

greatest

for

instruments

categorized

in

Level

3.

In

certain

cases,

the

inputs

used

to

measure

fair

value

may

fall

into

different

levels

of

the

fair

value

hierarchy.

In

such

cases,

for

disclosure

purposes,

the

level

in

the

fair

value

hierarchy

within

which

the

fair

value

measurement

in

its

entirety

falls

is

determined

based

on

the

lowest

level

input

that

is

significant

to

the

fair

value

measurement

in

its

entirety.

Fair

value

is

a

market-based

measure

considered

from

the

perspective

of

a

market

participant

who

holds

the

asset

rather

than

an

entity

specific

measure.

Therefore,

even

when

market

assumptions

are

not

readily

available,

the

Funds’

own

assumptions

are

set

to

reflect

those

that

market

participants

would

use

in

pricing

the

asset

or

liability

at

the

measurement

date.

The

Funds

uses

prices

and

inputs

that

are

current

as

of

the

measurement

date,

when

available.

Investments

which

are

included

in

the

Level

3

category

may

be

valued

using

quoted

prices

from

brokers

and

dealers

participating

in

the

market

for

these

investments.

These

investments

are

classified

as

Level

3

investments

due

to

the

lack

of

market

transparency

and

market

corroboration

to

support

these

quoted

prices.

Valuation

models

may

be

used

as

the

pricing

source

for

other

investments

classified

as

Level

3.

Valuation

models

rely

on

one

or

more

significant

unobservable

inputs

such

as:

yield

to

maturity,

EBITDA

multiples,

discount

rates,

available

cash,

or

direct

offering

price.

Significant

increases

in

yield

to

maturity,

EBITDA

multiples,

available

cash,

or

direct

offering

price would

have

resulted

in

significantly

higher

fair

value

measurements.

A

significant

increases

in

discount

rates

would

have

resulted

in

a

significantly

lower

fair

value

measurement.

Benchmark

pricing

procedures

set

the

base

price

of

a

security

based

on

current

market

data.

The

base

price

may

be

a

broker-dealer

quote,

transaction

price,

or

internal

value

based

on

relevant

market

data.

The

fair

values

of

these

securities

are

dependent

on

economic,

political,

and

other

considerations.

The

values

of

such

securities

may

be

affected

by

significant

changes

in

the

economic

conditions,

changes

in

government

policies,

and

other

factors

(e.g.,

natural

disasters,

pandemics,

accidents,

conflicts,

etc.).

The

inputs

or

methodology

used

for

valuing

securities

are

not

necessarily

an

indication

of
