RETIREMENT

LEADERSHIP

Dear

Shareholder,

The

frenzy

about

imminent

recession

seemed

to

peak

in

August,

but

there

are

still

few

clear

signs

of

recovery.

On

the

edges,

though,

economic

momentum

feels

better.

Pulling

the

economy

back

from

the

brink

were

robust

household

spending,

solid

labor

markets,

healthy

wage

growth,

super-low

long-term

interest

rates,

and

easier

central

bank

policy.

In

China,

headlines

described

the

August

data

as

disappointing,

with

key

sectors

experiencing

slower

year-over-year

growth

than

July,

but

there’s

been

monthly

sequential

progress

since

the

low

earlier

this

year.

The

Eurozone

is

a

slightly

different

story.

Preliminary

results

of

September

business

surveys

were

well

below

expectations.

However,

overall

Euro-area

bank

loans

and

the

money

supply

are

rising,

job

growth

is

still

okay,

and

households

appear

resilient.

The

Japanese

economy

surprised

positively

in

the

first

half,

but,

like

the

Eurozone,

is

being

worn

down

by

the

global

slump.

The

U.S.

may

be

the

closest

to

a

clear

recovery

from

the

world

economic

stumble

of

the

last

20

months.

Geopolitical

risks

are

large

and

well

known.

But

the

biggest

recession

risk

seems

to

be

a

deterioration

in

corporate

profits.

We

continue

to

believe

that

the

most

prudent

approach

for

investing

is

to

select

a

portfolio

allocation

that

is

broadly

diversified

both

across

and

within

asset

classes.

We

encourage

you

to

work

closely

with

your

financial

professional

to

select

and

monitor

those

investments

best

suited

to

helping

you

work

toward

and

realize

your

financial

goals.

I

am

honored

to

join

our

team

at

Principal

Funds

to

continue

the

heritage

of

serving

you

for

your

retirement

and

wealth

management

goals.

Our

goal

is

to

meet

clients

with

a

variety

of

capabilities

that

service

their

needs

and

exceed

their

expectations.

The

continued

demand

for

product

innovation

combined

with

superior

execution

skills

has

become

a

key

differentiator

in

our

business.

Our

focus

at

Principal

Funds

has

always

been

on

consistent,

long-term

performance

for

our

investors.

Our

investment

strategies

cover

a

wide

range

of

asset

classes

to

help

you

diversify

your

portfolio

as

you

save

for

the

future—whether

you

are

investing

for

goals

that

are

years

down

the

road

or

closer

at

hand.

your

continued

trust

and

financial

commitment

our

family.

Principal

Diversified

Select

Real

Fund

(the

"Fund")

is

registered

under

the

Investment

Company

Act

of

1940,

as

amended,

as

a

diversified,

closed-end

management

investment

company.

The

Fund

continuously

offers

three

classes

of

shares:

Class

A,

Class

Y,

and

Institutional.

The

Fund

was

organized

as

a

Delaware

statutory

trust

on

September

21,

2018

pursuant

to

an

Agreement

and

Declaration

of

Trust

governed

by

the

State

of

Delaware.

Principal

Global

Investors,

LLC

(the

“Manager”)

serves

as

the

Fund’s

manager

and

advisor.

The

Fund

is

structured

as

an

interval

fund,

meaning

it

conducts

quarterly

repurchase

offers

of

no

less

than

5%

and

no

more

than

25%

of

the

Fund’s

outstanding

shares

at

net

value.

Repurchase

offers

of

more

than

5%

are

made

solely

at

the

discretion

of

the

Fund’s

Board

of

Trustees

(the

“Board”),

and

investors

should

not

rely

on

any

expectation

of

repurchase

offers

being

made

in

excess

of

5%.

Investors

should

consider

the

Fund’s

shares

illiquid.

The

Fund’s

shares

are

not

listed

on

any

national

securities

exchange

and

are

not

publicly

Significant

Accounting

Policies

The

preparation

of

financial

statements

in

conformity

with

U.S.

generally

accepted

accounting

principles

(“U.S.

GAAP”)

requires

management

to

make

estimates

and

assumptions

that

affect

the

reported

amounts

of

assets

and

liabilities

and

disclosure

of

contingent

assets

and

liabilities

at

the

date

of

the

financial

statements

and

the

reported

amounts

of

revenues

and

expenses

during

the

reporting

period.

Actual

results

could

differ

from

those

estimates.

The

following

summarizes

the

significant

accounting

policies

of

the

Fund:

Security

Valuation.

The

Fund

values

securities

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

the

Manager

under

procedures

established

and

periodically

reviewed

by

the

Board.

The

Fund

invests

in

other

publicly

traded

investment

funds

which

are

valued

at

the

respective

fund’s

net

asset

value.

In

addition,

the

Fund

invests

a

portion

of

its

assets

in

private

investment

funds

which

are

valued

at

fair

value

based

upon

the

net

asset

value

reported

on

a

periodic

basis.

The

appropriateness

of

the

fair

value

of

these

securities

is

monitored

by

the

Manager.

The

shares

of

other

investment

funds

are

referred

to

as

the

“Underlying

Funds”.

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

Fund’s

net

asset

value

are

reflected

in

the

Fund’s

net

asset

value

and

these

securities

are

valued

at

fair

value

as

determined

in

good

faith

by

the

Manager

under

procedures

established

and

periodically

reviewed

by

the

Board.

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

ADRs,

futures

contracts,

industry

indices,

general

indices,

and

foreign

currencies.

To

the

extent

the

Fund

invests

in

foreign

securities

listed

on

foreign

exchanges

which

trade

on

days

on

which

the

Fund

does

not

determine

net

asset

value,

for

example

weekends

and

other

customary

national

U.S.

holidays,

the

Fund’s

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.

Income

and

Investment

Transactions.

The

Fund

records

investment

transactions

on

a

trade

date

basis.

Trade

date

for

senior

floating

rate

interests

purchased

in

the

primary

market

is

considered

the

date

on

which

the

loan

allocations

are

determined.

Trade

date

for

senior

floating

rate

interests

purchased

in

the

secondary

market

is

the

date

on

which

the

transaction

is

entered

into.

The

identified

cost

basis

has

been

used

in

determining

the

net

realized

gain

or

loss

from

investment

transactions

and

unrealized

appreciation

or

depreciation

of

investments.

The

Fund

records

dividend

income

on

the

ex-dividend

date,

except

dividend

income

from

foreign

securities

whereby

the

ex-dividend

date

has

passed;

such

dividends

are

recorded

as

soon

as

the

Fund

is

informed

of

the

ex-dividend

date.

Interest

income

is

recognized

on

an

accrual

basis.

Discounts

and

premiums

on

securities

are

accreted/amortized,

respectively,

on

the

level

yield

method

over

the

expected

lives

of

the

respective

securities.

Callable

debt

securities

purchased

at

a

premium

are

amortized

to

the

earliest

call

date.

The

Fund

allocates

all

income

and

realized

and

unrealized

gains

or

losses

on

a

daily

basis

to

each

class

of

shares

based

upon

the

relative

proportion

of

the

value

of

shares

outstanding

of

each

class.

Expenses.

Expenses

directly

attributed

to

the

Fund

are

charged

to

the

Fund.

Other

expenses

not

directly

attributed

to

the

Fund

are

apportioned

among

the

registered

investment

companies

managed

by

the

Manager.

Management

fees

are

allocated

daily

to

each

class

of

shares

based

upon

the

relative

proportion

of

the

value

of

shares

outstanding

of

each

class.

Expenses

specifically

attributable

to

a

particular

class

are

charged

directly

to

such

class

and

are

included

separately

in

the

statement

of

operations.

In

addition

to

the

expenses

the

Fund

bears

directly,

the

Fund

may

indirectly

bear

a

pro

rata

share

of

the

fees

and

expenses

of

the

Underlying

Funds

in

which

it

invests.

Because

the

Underlying

Funds

have

varied

expense

levels

and

the

Fund

may

own

different

proportions

of

Underlying

Funds

at

different

times,

the

amount

of

expense

incurred

indirectly

by

the

Fund

will

vary.

Expenses

included

in

the

statement

of

operations

of

the

Fund

do

not

include

any

expenses

associated

with

the

Underlying

Funds.

Distributions

to

Shareholders.

Dividends

and

distributions

to

shareholders

of

the

Fund

are

recorded

on

the

ex-dividend

date.

Dividends

and

distributions

to

shareholders

from

net

investment

income

and

net

realized

gain

from

investments

are

determined

in

accordance

with

federal

tax

regulations,

which

may

differ

from

U.S.

GAAP.

These

differences

are

primarily

due

to

differing

treatments

for

losses

deferred

due

to

wash

sales.

Permanent

book

and

tax

basis

differences

are

reclassified

within

the

capital

accounts

based

on

federal

tax-basis

treatment;

temporary

differences

do

not

require

reclassification.

To

the

extent

dividends

and

distributions

exceed

current

and

accumulated

earnings

and

profits

for

federal

income

tax

purposes;

they

are

reported

as

return

of

capital

distributions.

Distributions

from

REITs

may

be

characterized

as

ordinary

income,

net

capital

gain,

or

a

return

of

capital

to

the

Fund.

The

proper

characterization

of

REIT

distributions

is

generally

not

known

until

after

the

end

of

each

calendar

year.

As

such,

estimates

are

used

in

reporting

the

character

of

income

and

distributions

for

financial

statement

purposes.

Federal

Income

Taxes.

No

provision

for

federal

income

taxes

is

considered

necessary

because

the

Fund

intends

to

qualify

as

a

“regulated

investment

company”

under

the

Internal

Revenue

Code

and

intends

to

distribute

each

year

substantially

all

of

its

net

investment

income

and

realized

capital

gains

to

shareholders.

Management

evaluates

tax

positions

taken

or

expected

to

be

taken

in

the

course

of

preparing

the

Fund’s

tax

returns

to

determine

whether

it

is

“more

likely

than

not”

that

each

tax

position

would

be

sustained

upon

examination

by

a

taxing

authority

based

on

the

technical

merits

of

the

position.

Tax

positions

not

deemed

to

meet

the

more

likely

than

not

threshold

would

be

recorded

as

a

tax

benefit

or

expense

in

the

current

year.

During

the

period

ended

September

30,

2019

,

the

Fund

did

not

record

any

such

tax

benefit

or

expense

in

the

accompanying

financial

statements.

Operating

Policies

Cross

Trades.

The

Fund

may

engage

in

cross

trades.

A

cross

trade

is

a

purchase

or

sale

transaction

between

affiliated

portfolios

executed

directly

or

through

an

intermediary.

Entities

may

be

considered

affiliated

if

they

have

a

common

investment

advisor,

so

a

fund

may

be

considered

affiliated

with

any

portfolio

for

which

the

Fund's

sub-advisor

acts

as

an

investment

advisor.

Such

transactions

are

permissible

provided

that

the

conditions

of

Rule

17a-7

under

the

Investment

Company

Act

of

1940

are

satisfied.

Illiquid

Securities.

Illiquid

securities

generally

cannot

be

sold

or

disposed

of

in

the

ordinary

course

of

business

(within

seven

calendar

days)

at

approximately

the

value

at

which

the

Fund

has

valued

the

investments.

This

may

have

an

adverse

effect

on

the

Fund’s

ability

to

dispose

of

particular

illiquid

securities

at

fair

value

and

may

limit

the

Fund’s

ability

to

obtain

accurate

market

quotations

for

purposes

of

valuing

the

securities. 

Indemnification.

Under

the

Fund’s

by-laws,

present

and

past

officers,

trustees

and

employees

are

indemnified

against

certain

liabilities

arising

out

of

the

performance

of

their

duties.

In

addition,

in

the

normal

course

of

business,

the

Fund

may

enter

into

a

variety

of

contracts

that

may

contain

representations

and

warranties

which

provide

general

indemnifications.

The

Fund’s

maximum

exposure

under

these

arrangements

is

unknown,

as

this

would

involve

future

claims

that

may

be

made

against

the

Fund.

Restricted

Securities.

The

Fund

may

invest

in

securities

that

are

subject

to

legal

or

contractual

restrictions

on

resale.

These

securities

generally

may

be

resold

in

transactions

exempt

from

registration

or

to

the

public

if

the

securities

are

registered.

Disposal

of

these

securities

may

involve

time-consuming

negotiations

and

expense,

and

prompt

sale

at

an

acceptable

price

may

be

difficult. 

Unfunded

Commitments.

As

of

September

30,

2019,

the

Fund

had

unfunded

commitments

relating

to

potential

future

investments

not

currently

held

as

reported

below

(amounts

in

thousands):

4.

Fair

Valuation

Fair

value

is

defined

as

the

price

that

the

Fund

would

receive

upon

selling

a

security

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

Fund

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.

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.

The

type

of

securities

included

in

Level

1

includes

listed

equities

and

listed

derivatives.

Level

2

–

Other

significant

observable

inputs

(including

quoted

prices

for

similar

investments,

interest

rates,

prepayments

speeds,

credit

risk,

etc.).

Investments

which

are

generally

included

in

this

category

include

certain

foreign

equities,

corporate

bonds,

senior

floating

rate

interests,

municipal

bonds,

and

US

Government

and

Government

Agency

Obligations.

Level

3

–

Significant

unobservable

inputs

(including

the

Fund’s

assumptions

in

determining

the

fair

value

of

investments).

Investments

which

are

generally

included

in

this

category

include

certain

common

stocks,

corporate

bonds,

mortgage

backed

securities

or

senior

floating

rate

interests.

In

,

the

has

elected

to

apply

the

practical

expedient

to

its

investments

in

private

investment

funds

at

their

respective

net

asset

value

each

calendar

quarter.

These

investments

are

excluded

from

the

fair

value

hierarchy.

The

availability

of

observable

inputs

can

vary

from

security

to

security

and

is

affected

by

a

wide

variety

of

factors,

including,

the

type

of

whether

the

security

is

and

not

of

fair

value

requires

more

judgment.

Accordingly,

the

degree

of

judgment

exercised

by

the

Fund

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

Fund’s

own

assumptions

are

set

to

reflect

those

that

market

participants

would

use

in

pricing

the

asset

or

liability

at

the

measurement

date.

The

Fund

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

prepayment

rates,

probability

of

default,

or

loss

severity

in

the

event

of

default.

Significant

increases

in

any

of

those

inputs

in

isolation

would

result

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,

accidents,

conflicts,

etc.).

Fair

value

of

these

investments

is

determined

in

good

faith

by

the

Manager

under

procedures

established

and

periodically

reviewed

by

the

Board.

The

Valuation

Committee

meets

at

least

monthly

and

reports

directly

to

the

Board.

A

pricing

group

(the

“Pricing

Group”),

who

reports

to

the

Valuation

Committee,

relies

on

the

established

pricing

policies

to

determine

fair

valuation.

Included

in

the

pricing

policies

is

an

overview

of

the

approved

valuation

approaches

established

for

each

asset

class.

The

Pricing

Group

will

consider

all

appropriate

information

available

when

determining

fair

valuation.

The

Pricing

Group

relies

on

externally

provided

valuation

inputs

to

determine

the

value

of

Level

3

securities.

Security

values

are

updated

as

new

information

becomes

available.

Valuation

data

and

changes

in

valuation

amounts

are

reviewed

on

a

daily

basis

based

on

specified

criteria

for

the

security,

asset

class,

and

other

factors.

In

addition,

valuation

data

is

periodically

compared

to

actual

transactions

executed

by

the

Fund

(i.e.,

purchases/sales)

and

differences

between

transaction

prices

and

prior

period

valuation

data

are

investigated

based

on

specified

tolerances.

Fund’s

average

daily

net

assets.

A

portion

sub-advisors

of

the

Fund,

which

may

be

As

a

shareholder

of

Principal

Diversified

Select

Real

Asset

Fund,

you

incur

two

types

of

costs:

(1)

transaction

costs,

including

sales

charges

on

purchase

payments

and

contingent

deferred

sales

charges;

and

(2)

ongoing

costs,

including

management

fees;

distribution

fees;

and

other

fund

expenses.

In

addition

to

the

expenses

the

Fund

bear

directly,

the

Fund

may

indirectly

bear

its

pro

rata

share

of

the

expenses

incurred

by

the

investment

companies

in

which

the

Fund

invests.

This

Example

is

intended

to

help

you

understand

your

ongoing

costs

(in

dollars)

of

investing

in

Principal

Diversified

Select

Real

Asset

Fund

and

to

compare

these

costs

with

the

ongoing

costs

of

investing

in

other

mutual

funds.

The

Example

is

based

on

an

investment

of

$1,000

invested

at

the

beginning

of

the

period

and

held

for

the

entire

period

(April

1,

2019

to

September

30,

2019),

unless

otherwise

noted.

Actual

Expenses

The

first

section

of

the

table

below

provides

information

about

actual

account

values

and

actual

expenses.

You

may

use

the

information

in

this

section,

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

in

the

first

section

under

the

heading

entitled

“Expenses

Paid

During

Period”

to

estimate

the

expenses

you

paid

on

your

account

during

this

period.

Additional

account

fees

may

apply

to

certain

types

of

investment

products

which

are

not

included

in

the

table

below.

If

they

were,

the

estimate

of

expenses

you

paid

during

the

period

would

be

higher,

and

your

ending

account

value

lower,

by

this

amount.

Hypothetical

Example

for

Comparison

Purposes

The

second

section

of

the

table

below

provides

information

about

hypothetical

account

values

and

hypothetical

expenses

based

on

the

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

the

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

transaction

costs,

such

as

sales

charges

on

purchase

payments,

contingent

deferred

sales

charges,

redemption

fees

or

exchange

fees.

Therefore,

the

second

section

of

the

table

is

useful

in

comparing

ongoing

costs

only,

and

will

not

help

you

determine

the

relative

total

costs

of

owning

different

funds.

In

addition,

if

these

transaction

costs

were

included,

your

costs

would

have

been

higher.

requesting

and

reviewing

materials.

The

Audit

Committee’s

primary

purpose

is

to

assist

the

Board

in

fulfilling

certain

of

its

responsibilities.

The

Audit

Committee

serves

as

an

independent

and

objective

party

to

monitor

the

Fund

Complex’s

accounting

policies,

financial

reporting

and

internal

control

system,

as

well

as

the

work

of

the

independent

registered

public

accountants.

The

Audit

Committee

assists

Board

oversight

of

1)

the

integrity

of

the

financial

statements;

2)

the

Fund

Complex’s

compliance

with

requirements;

3)

independent

registered

public

accountants’

qualifications

and

independence;

and

4)

the

performance

of

the

Fund

Complex’s

independent

registered

accountants.

The

Audit

Committee

also

provides

an

open

avenue

of

communication

among

the

independent

registered

public

accountants,

the

Manager’s

internal

auditors,

Fund

Complex

management,

and

the

Board.

The

Executive

Committee’s

primary

purpose

is

to

exercise

certain

powers

of

the

Board

when

the

Board

is

not

in

session.

When

the

Board

is

not

in

session,

the

Committee

may

exercise

all

powers

of

The

Nominating

and

Governance

Committee’s

primary

purpose

is

to

oversee

the

structure

and

efficiency

of

the

Board

and

the

committees

established

by

the

Board.

The

Committee

responsibilities

include

evaluating

Board

membership

and

functions,

committee

membership

and

functions,

insurance

coverage,

and

legal

matters.

The

nominating

functions

of

the

Committee

include

selecting

and

nominating

all

candidates

who

are

not

“interested

persons”

of

the

Fund

Complex

for

election

to

the

Board.

Generally,

the

Committee

requests

trustee

nominee

suggestions

from

the

committee

members

and

management.

In

addition,

the

Committee

will

consider

Trustee

candidates

recommended

by

shareholders

of

the

Fund

Complex.

Recommendations

should

be

submitted

in

writing

to

Principal

Funds,

Inc.

at

711

High

Street,

Des

Moines,

IA

50392.

When

evaluating

a

person

as

a

potential

nominee

to

serve

as

an

Independent

Trustee,

the

Committee

will

generally

consider,

among

other

factors:

age;

education;

relevant

business

experience;

geographical

factors;

whether

the

person

is

“independent”

and

otherwise

qualified

under

applicable

laws

and

regulations

to

serve

as

a

trustee;

and

whether

the

person

is

willing

to

serve,

and

willing

and

able

to

commit

the

time

necessary

for

attendance

at

meetings

and

the

performance

of

the

duties

of

an

independent

trustee.

The

Committee

also

meets

personally

with

the

nominees

and

conducts

a

reference

check.

The

final

decision

is

based

on

a

combination

of

factors,

including

the

strengths

and

the

experience

an

individual

may

bring

to

the

Board.

The

Committee

believes

the

Board

generally

benefits

from

diversity

of

background,

experience

and

views

among

its

members,

and

considers

these

factors

in

evaluating

the

composition

of

the

Board.

BOARD

CONSIDERATION

OF

INVESTMENT

ADVISORY

CONTRACTS

During

the

period

covered

by

this

report,

the

Board

of

Trustees

(the

“Board”)

of

the

Principal

Diversified

Select

Real

Asset

Fund

(the

“Fund”)

approved

a

sub-sub-advisory

agreement

between

Principal

Global

Investors,

LLC

(the

“Manager”),

Tortoise

Capital

Advisers,

L.L.C.

(the

“Sub-advisor”)

and

Tortoise

Credit

Strategies,

LLC

(the

“Sub-Sub-Advisor”)

with

respect

to

a

private

social

infrastructure

debt

strategy

of

the

Fund.

TCS

Sub-Sub-Advisory

Agreement

–

Principal

Diversified

Select

Real

Asset

Fund

On

September

10,

2019,

the

Board

considered

whether

to

approve

a

sub-sub-advisory

agreement

(the

“Sub-Sub-Advisory

Agreement”)

among

the

Manager,

the

Subadvisor

and

the

Sub-Sub-Advisor

with

respect

to

a

private

social

infrastructure

debt

strategy

of

the

Fund.

Based

upon

their

review,

the

Board

concluded

that

it

was

in

the

best

interests

of

the

Fund

to

approve

the

Sub-Sub-Advisory

Agreement

and,

accordingly,

recommended

to

the

Board

the

approval

of

the

Sub-Sub-Advisory

Agreement.

In

reaching

this

conclusion,

no

single

factor

was

determinative

in

the

Board’s

analysis,

but

rather

the

Board

considered

a

variety

of

factors.

The

Board

considered

various

factors,

including

the

following,

and

made

certain

findings

and

conclusions

with

regard

thereto,

in

approving

the

Sub-Sub-Advisory

Agreement.

Nature,

Quality

and

Extent

of

Services.

The

Board

considered

the

nature,

quality

and

extent

of

the

services

expected

to

be

provided

under

the

Sub-Sub-Advisory

Agreement.

The

Board

considered

the

reputation,

qualifications

and

background

of

the

Sub-Sub-Advisor,

the

investment

approach

of

the

Sub-Sub-Advisor,

the

experience

and

skills

of

the

Sub-Sub-Advisor’s

investment

personnel

who

would

be

responsible

for

the

day-to-day

management

of

the

Fund

and

the

resources

made

available

to

such

personnel.

The

Board

noted

that

the

Sub-Advisor,

which

is

an

affiliate

under

common

control

with

the

Sub-Sub-Advisor,

currently

provides

sub-advisory

services

to

an

investment

sleeve

of

the

Fund

and

an

investment

sleeve

of

a

series

of

Principal

Funds,

Inc.,

and

that

the

Board

had

reviewed

and

recommended

for

renewal

those

sub-advisory

agreements

at

their

September

2019

meeting.

In

addition,

the

Board

considered

the

Manager’s

program

for

recommending,

monitoring

and

replacing

sub-

advisors

(including

sub-sub-advisors)

and

that

the

Manager

recommended

the

Sub-Sub-Advisor

based

upon

that

program.

Investment

Performance.

The

Board

reviewed

the

historical

oneyear

and

since

inception

(January

27,

2017)

performance

returns,

gross

and

net

of

Fund

expenses,

as

of

June

30,

2019

of

a

portfolio

that

the

Sub-Sub-Advisor

currently

manages

in

accordance

with

the

Sub-Sub-Advisor’s

proposed

investment

strategy

for

the

Fund,

as

compared

to

the

historical

performance

returns

of

a

relevant

benchmark

index

and

two

relevant

Morningstar

categories.

The

Board

concluded,

based

upon

the

information

provided,

that

the

Sub-Sub-Advisor

is

qualified.

Fees,

Economies

of

Scale

and

Profitability.

The

Board

considered

the

proposed

sub-sub-advisory

fee,

noting

that

the

Sub-Advisor

would

compensate

the

Sub-Sub-Advisor

from

its

own

sub-advisory

fee

and,

in

turn,

that

the

Manager

compensates

the

Sub-Advisor

from

its

own

management

fee,

so

that

shareholders

would

pay

only

the

management

fee.

The

Board

noted

that

the

proposed

sub-sub-advisory

fee

schedule

includes

breakpoints

and

concluded

that

the

sub-sub-advisory

fee

schedule

reflects

an

appropriate

recognition

of

economies

of

scale

at

currently

anticipated

asset

levels.

The

Board

considered

the

Manager’s

statement

that

it

found

the

proposed

sub-advisory

and

sub-sub-advisory

fee

schedules

to

be

competitive.

The

Board

also

considered

that

the

Sub-Sub-Advisor’s

appointment

was

contingent

upon

the

Fund’s

shareholders

approving

the

Sub-Sub-

Advisory

Agreement,

and

that

the

Manager

would

cover

the

costs

of

filing

and

distributing

an

information

statement.

On

the

basis

of

the

information

provided,

the

Board

concluded

that

the

proposed

sub-sub-advisory

fee

was

reasonable.

Other

Benefits.

The

Board

also

considered

the

character

and

amount

of

other

fall-out

benefits

to

be

received

by

the

Sub-Sub-Advisor.

The

Board

noted

that

the

Sub-Advisor

and

the

Sub-Sub-Advisor

will

not

utilize

soft

dollars

in

connection

with

the

services

provided

to

the

Fund.

The

Board

further

noted

the

Manager’s

statement

that

there

would

be

no

known

fall-out

benefits.

Overall

Conclusions.

Based

upon

all

of

the

information

considered

and

the

conclusions

reached,

the

Board

determined

that

the

terms

of

the

Sub-Sub-Advisory

Agreement

were

fair

and

reasonable,

and

that

approval

of

the

Sub-Sub-Advisory

Agreement

was

in

the

best

interests

of

the

Fund.

Accordingly,

the

Board

approved

the

Sub-Sub-Advisory

Agreement.
