Dear

Shareholder

Most

major

global

stock

and

bond

indexes

produced

positive

returns

during

the

first

half

of

your

fund’s

fiscal

year,

the

six-month

period

ended

June

30,

2023.

Despite

turmoil

in

the

banking

sector

and

a

protracted

debt

ceiling

standoff,

markets

were

resilient

as

growth

remained

positive

in

the

major

economies

and

corporate

earnings

results

came

in

stronger

than

expected.

For

the

six-month

period,

the

technology-oriented

Nasdaq

Composite

Index

gained

more

than

30%,

the

strongest

result

of

the

major

benchmarks,

as

tech

companies

benefited

from

investor

enthusiasm

for

artificial

intelligence

applications.

Growth

stocks

outperformed

value

shares,

and

developed

market

stocks

generally

outpaced

their

emerging

market

counterparts.

Currency

movements

were

mixed

over

the

period,

although

a

weaker

dollar

versus

major

European

currencies

was

beneficial

for

U.S.

investors

in

European

securities.

Within

the

S&P

500

Index,

the

information

technology,

communication

services,

and

consumer

discretionary

sectors

were

all

lifted

by

the

tech

rally

and

recorded

significant

gains.

Conversely,

the

defensive

utilities

sector

had

the

weakest

returns

in

the

growth-focused

environment,

and

the

energy

sector

also

lost

ground

amid

declining

oil

prices.

The

financials

sector

partly

recovered

from

the

failure

of

three

large

regional

banks

during

the

period

but

still

finished

with

modest

losses.

Cheaper

oil

contributed

to

slowing

inflation,

although

core

inflation

readings—

which

exclude

volatile

food

and

energy

prices—remained

stubbornly

high.

In

response,

the

Federal

Reserve

raised

its

short-term

lending

benchmark

rate

to

a

target

range

of

5.00%

to

5.25%

by

early

May,

the

highest

level

since

2007.

The

Fed

held

rates

steady

at

its

June

meeting,

but

policymakers

indicated

that

two

more

rate

hikes

could

come

by

the

end

of

the

year.

In

the

fixed

income

market,

returns

were

generally

positive

across

most

sectors

as

investors

benefited

from

the

higher

interest

rates

that

have

become

available

over

the

past

year.

Investment-grade

corporate

bonds

were

supported

by

generally

solid

balance

sheets

and

were

among

the

strongest

performers.

Global

economies

and

markets

showed

surprising

resilience

in

recent

months,

but,

moving

into

the

second

half

of

2023,

we

believe

investors

could

face

potential

challenges.

The

impact

of

the

Fed’s

rate

hikes

has

yet

to

be

fully

felt

in

the

economy,

and

while

the

regional

banking

turmoil

appears

to

have

been

contained

by

the

swift

actions

of

regulators,

it

could

weigh

on

credit

conditions.

Moreover,

market

consensus

still

seems

to

point

to

a

coming

recession,

although

hopes

have

emerged

that

such

a

downturn

could

be

more

modest.

We

believe

this

environment

makes

skilled

active

management

a

critical

tool

for

identifying

risks

and

opportunities,

and

our

investment

teams

will

continue

to

use

fundamental

research

to

identify

securities

that

can

add

value

to

your

portfolio

over

the

long

term.

You

may

notice

that

this

report

no

longer

contains

the

commentary

on

your

fund’s

performance

and

positioning

that

we

previously

included

in

the

semiannual

shareholder

letters.

The

Securities

and

Exchange

Commission

(SEC)

adopted

new

rules

in

January

that

will

require

fund

reports

to

transition

to

a

new

format

known

as

a

Tailored

Shareholder

Report.

This

change

will

require

a

much

more

concise

summary

of

performance

rather

than

the

level

of

detail

we

have

provided

historically

while

also

aiming

to

be

more

visually

engaging.

As

we

prepare

to

make

changes

to

the

annual

reports

to

meet

the

new

report

regulatory

requirements

by

mid-2024,

we

felt

the

time

was

right

to

discontinue

the

optional

six-month

semiannual

fund

letter

to

focus

on

the

changes

to

come.

While

semiannual

fund

letters

will

no

longer

be

produced,

you

may

continue

to

access

current

fund

information

as

well

as

insights

FUND

EXPENSE

EXAMPLE

As

a

mutual

fund

shareholder,

you

may

incur

two

types

of

costs:

(1)

transaction

costs,

such

as

redemption

fees

or

sales

loads,

and

(2)

ongoing

costs,

including

management

fees,

distribution

and

service

(12b-1)

fees,

and

other

fund

expenses.

The

following

example

is

intended

to

help

you

understand

your

ongoing

costs

(in

dollars)

of

investing

in

the

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

most

recent

six-month

period

and

held

for

the

entire

period.

Please

note

that

the

fund

has

three

share

classes:

The

Investor

Class

charges

no

distribution

and

service

(12b-1)

fee, the

I

Class

shares

are

also

available

to

institutionally

oriented

clients

and

impose

no

12b-1

or

administrative

fee

payment,

and

Z

Class

shares

are

offered

only

to

funds

advised

by

T.

Rowe

Price

and

other

advisory

clients

of

T.

Rowe

Price

or

its

affiliates

that

are

subject

to

a

contractual

fee

for

investment

management

services

and

impose

no

12b-1

fee

or

administrative

fee

payment.

Each

share

class

is

presented

separately

in

the

table.

Actual

Expenses

The

first

line

of

the

following

table

(Actual)

provides

information

about

actual

account

values

and

actual

expenses.

You

may

use

the

information

on

this

line,

together

with

your

account

balance,

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

on

the

first

line

under

the

heading

“Expenses

Paid

During

Period”

to

estimate

the

expenses

you

paid

on

your

account

during

this

period. 

Hypothetical

Example

for

Comparison

Purposes

The

information

on

the

second

line

of

the

table

(Hypothetical)

is

based

on

hypothetical

account

values

and

expenses

derived

from

the

fund’s

actual

expense

ratio

and

an

assumed

5%

per

year

rate

of

return

before

expenses

(not

the

fund’s

actual

return).

You

may

compare

the

ongoing

costs

of

investing

in

the

fund

with

other

funds

by

contrasting

this

5%

hypothetical

example

and

the

5%

hypothetical

examples

that

appear

in

the

shareholder

reports

of

the

other

funds.

The

hypothetical

account

values

and

expenses

may

not

be

used

to

estimate

the

actual

ending

account

balance

or

expenses

you

paid

for

the

period.

Note:

T.

Rowe

Price

charges

an

account

service

fee

that

is

not

included

in

the

accompanying

table.

The

account

service

fee

is

charged

on

a

quarterly

basis,

usually

during

the

last

week

of

a

calendar

quarter,

and

applies

to

accounts

with

balances

below

$10,000

on

the

day

of

the

assessment.

The

fee

is

charged

to

accounts

that

fall

below

$10,000

for

any

reason,

including

market

fluctuations,

redemptions,

or

exchanges.

When

an

account

with

less

than

$10,000

is

closed

either

through

redemption

or

exchange,

the

fee

is

charged

and

deducted

from

the

proceeds.

The

fee

applies

to

IRAs

but

not

to

retirement

plans

directly

registered

with

T.

Rowe

Price

Services

or

accounts

maintained

by

intermediaries

through

NSCC

®

Networking.

If

you

are

subject

to

the

fee,

keep

it

in

mind

when

you

are

estimating

the

ongoing

expenses

of

investing

in

the

fund

and

when

comparing

the

expenses

of

this

fund

with

other

funds.

You

should

also

be

aware

that

the

expenses

shown

in

the

table

highlight

only

your

ongoing

costs

and

do

not

reflect

any

transaction

costs,

such

as

redemption

fees

or

sales

loads.

Therefore,

the

second

line

of

the

table

is

useful

in

comparing

ongoing

costs

only

and

will

not

help

you

determine

the

relative

total

costs

of

owning

different

funds.

To

the

extent

a

fund

charges

transaction

costs,

however,

the

total

cost

of

owning

that

fund

is

higher.

The

(the

is

an

open-

company

established

by

the

corporation

and

intends

to

be

diversified

in

approximately

the

same

proportion

as

the

index

it

tracks

is

diversified.

The

fund

may

become

nondiversified

for

periods

of

time

solely

as

a

result

of

changes

in

the

composition

of

the

index

(for

example,

changes

in

the

relative

market

capitalization

or

index

weighting

of

one

or

more

securities

represented

in

the

index). The

fund

seeks

to

track

the

performance

of

a

benchmark

index

that

measures

the

investment

return

of

small-capitalization

U.S.

stocks.

The

fund

is

available

for

only

by

although

the

ACCOUNTING

POLICIES 

Basis

of

Preparation

 The fund

is

an

investment

company

and

follows

accounting

and

reporting

guidance

in

the

Financial

Accounting

Standards

Board

(FASB)

Accounting

Standards

Codification

Topic

946

(ASC

The

accompanying

financial

statements

were

prepared

in

accordance

with

accounting

principles

generally

accepted

in

the

United

States

of

America

(GAAP),

including,

but

not

limited

to,

ASC

946.

GAAP

requires

the

use

of

estimates

made

by

management.

Management

believes

that

estimates

and

valuations

are

appropriate;

however,

actual

results

may

differ

from

those

estimates,

and

the

valuations

reflected

in

the

accompanying

financial

statements

may

differ

from

the

value

ultimately

realized

upon

sale

or

maturity.

Investment

Transactions,

Investment

Income,

and

Distributions

 Investment

transactions

are

accounted

for

on

if

incurred,

are

recorded

as

expense.

Dividends

received

from other

investment

companies are

reflected

as

dividend

income;

capital

gain

distributions

are

reflected

as

realized

gain/

loss.

Dividend

income and

capital

gain

distributions

are

recorded

on

the

ex-dividend

date.

Distributions

from

REITs

are

initially

recorded

as

dividend

income

and,

to

the

extent

such

represent

a

return

of

capital

or

capital

gain

for

tax

purposes,

are

reclassified

when

such

information

becomes

Non-cash

dividends,

if

any,

are

recorded

at

of

the

asset

received.

Proceeds

from

are

included

in

either

Capital

Transactions

 Each

investor’s

interest

in

the

net

assets

of the

fund

is

represented

by

fund

shares. The

fund’s

net

asset

value

(NAV)

per

share

is

computed

at

the

close

of

the

New

York

Stock

Exchange

(NYSE),

normally

4

p.m.

ET,

each

day

the

NYSE

is

open

for

business.

However,

the

NAV

per

share

may

be

calculated

at

a

time

other

than

the

normal

close

of

the

NYSE

if

trading

on

the

NYSE

is

restricted,

if

the

NYSE

closes

earlier,

or

as

may

be

permitted

by

the

issued

Accounting

(ASU),

ASU

Fair

Value

Measurement

(Topic

820)

–

Fair

Value

Measurement

of

Equity

Securities

Subject

to

Contractual

Sale

Restrictions,

which

clarifies

that

a

contractual

restriction

on

the

sale

of

an

equity

security

is

not

considered

part

of

the

unit

of

account

of

the

equity

security

and,

therefore,

is

not

considered

in

measuring

fair

value.

The

amendments

under

this

ASU

are

effective

for

fiscal

years

beginning

after

December

15,

2023;

however,

the

fund

opted

to

early

adopt,

as

permitted,

effective

December

1,

2022. Adoption

of

the

guidance

did not

have

a

material

impact

on

VALUATION 

Fair

Value

  The

fund’s

financial

instruments

are

valued

at

the

close

of

the

NYSE

and

are

reported

at

fair

value,

which

GAAP

defines

as

the

price

that

would

be

received

to

sell

an

asset

or

paid

to

transfer

a

liability

in

an

orderly

transaction

between

market

participants

at

the

measurement

date. The fund’s

Board

of

Directors

(the

Board)

has

designated

T.

Rowe

Price

Associates,

Inc.

as

the

fund’s

valuation

designee

(Valuation

Designee).

Subject

to

oversight

by

the

Board,

the

Valuation

Designee

performs

the

following

functions

in

performing

fair

value

determinations:

assesses

and

manages

valuation

risks;

establishes

and

applies

fair

value

methodologies;

tests

fair

value

methodologies;

and

evaluates

pricing

vendors

and

pricing

agents.

The

duties

and

responsibilities

of

the

Valuation

Designee

are

performed

by

its

Valuation

Committee. The

Valuation

Designee provides

periodic

reporting

to

the

Board

on

valuation

matters.

Various

valuation

techniques

and

inputs

are

used

to

determine

the

fair

value

of

financial

instruments.

GAAP

establishes

the

following

fair

value

hierarchy

that

categorizes

the

inputs

used

to

measure

fair

value:

Level

1

–

quoted

prices

(unadjusted)

in

active

markets

for

identical

financial

instruments

that

the

fund

can

access

at

the

reporting

date

Level

2

–

inputs

other

than

Level

1

quoted

prices

that

are

observable,

either

directly

or

indirectly

(including,

but

not

limited

to,

quoted

prices

for

similar

financial

instruments

in

active

markets,

quoted

prices

for

identical

or

similar

financial

instruments

in

inactive

markets,

interest

rates

and

yield

curves,

implied

volatilities,

and

credit

spreads)

Level

3

–

unobservable

inputs

(including

the Valuation

Designee’s assumptions

in

determining

fair

value)

Observable

inputs

are

developed

using

market

data,

such

as

publicly

available

information

about

actual

events

or

transactions,

and

reflect

the

assumptions

that

market

participants

would

use

to

price

the

financial

instrument.

Unobservable

inputs

are

those

for

which

market

data

are

not

available

and

are

developed

using

the

best

information

available

about

the

assumptions

that

market

participants

would

use

to

price

the

financial

instrument.

GAAP

requires

valuation

techniques

to

maximize

the

use

of

relevant

T.

PRICE

Small-Cap

Index

Fund

72

observable

inputs

and

minimize

the

use

of

unobservable

inputs.

When

multiple

inputs

are

used

to

derive

fair

value,

the

financial

instrument

is

assigned

to

the

level

within

the

fair

value

hierarchy

based

on

the

lowest-level

input

that

is

significant

to

the

fair

value

of

the

financial

instrument.

Input

levels

are

not

necessarily

an

indication

of

the

risk

or

liquidity

associated

with

financial

instruments

at

that

level

but

rather

the

degree

of

judgment

used

in

determining

those

values.

Techniques 

Equity

including

exchange-traded

price

or,

for

certain

markets,

the

official

closing

price

at

the

time

the

valuations

are

made.

OTC

Bulletin

Board

securities

are

valued

at

the

mean

of

the

closing

bid

and

asked

prices.

A

security

that

is

listed

or

traded

on

more

than

one

exchange

is

valued

at

the

quotation

on

the

exchange

determined

to

be

the

primary

market

for

such

security.

Listed

securities

not

traded

on

a

particular

day

are

valued

at

the

mean

of

the

closing

bid

and

asked

prices

for

domestic

securities.

Debt

securities

generally

are

traded

in

the over-the-counter

(OTC)

market

and

are

valued

at

prices

furnished

by

independent

pricing

services

or

by

broker

dealers

who

make

markets

in

such

securities.

When

valuing

securities,

the

independent

pricing

services

consider

factors

such

as,

but

not

limited

to,

the

yield

or

price

of

bonds

of

comparable

quality,

coupon,

maturity,

and

type,

as

well

as

prices

quoted

by

dealers

who

make

markets

in

such

securities.

Investments

in

mutual

funds

are

valued

at

the

mutual

fund’s

closing

NAV

per

on

the

of

valuation.

Futures

are

valued

at

closing

settlement

prices.

Assets

and

liabilities

other

than

financial

instruments,

including

short-term

receivables

and

payables,

are

carried

at

cost,

or

estimated

realizable

value,

if

less,

which

approximates

fair

value. 

Investments

for

which

market

quotations are

not

readily

available

or

deemed

unreliable

are

valued

at

fair

value

as

determined

in

good

faith

by

the

Valuation

Designee.

The

Valuation

Designee

has

adopted

methodologies

for

determining

the

fair

value

of

investments

for

which

market

quotations

are

not

readily

available

or

deemed

unreliable,

including

the

use

of

other

pricing

sources.

Factors

used

in

determining

fair

value

vary

by

type

of

investment

and

may

include

market

or

investment

specific

considerations.

The

Valuation

Designee typically

will

afford

greatest

weight

to

actual

prices

in

arm’s

length

transactions,

to

the

extent

they

represent

orderly

transactions

between

market

participants,

transaction

information

can

be

reliably

obtained,

and

prices

are

deemed

representative

of

fair

value.

However,

the

Valuation

Designee may

also

consider

other

valuation

methods

such

as

market-based

valuation

multiples;

a

discount

or

premium

from

Fair

value

determinations

are

reviewed

on

basis.

Because

any

fair

value

determination

involves

a

significant

amount

of

judgment,

there

is

a

degree

of

subjectivity

inherent

in

such

pricing

decisions. Fair

value

prices

determined

by

the

differ

from

those

of

and

it

is

possible

that

DERIVATIVE

INSTRUMENTS 

During

the

six

months ended

June

30,

2023,

the

fund

invested

in

derivative

instruments.

As

defined

by

GAAP,

a

derivative

is

a

financial

instrument

whose

value

is

derived

from

an

underlying

security

price,

foreign

exchange

rate,

interest

rate,

index

of

prices

or

rates,

or

other

variable;

it

requires

little

or

no

initial

investment

and

permits

or

requires

net

settlement.

The

fund

invests

in

derivatives

only

if

the

expected

risks

and

rewards

are

consistent

with

its

investment

objectives,

policies,

and

overall

risk

profile,

as

described

in

its

prospectus

and

Statement

of

Additional

Information.

The

fund

may

use

derivatives

for

a

variety

of

purposes

and

may

use

them

to

establish

both

long

and

short

positions

within

the

fund’s

portfolio.

Potential

uses

include

to

hedge

against

declines

in

principal

value,

increase

yield,

invest

in

an

asset

with

greater

efficiency

and

at

a

lower

cost

than

is

possible

through

direct

investment,

to

enhance

return,

or

to

adjust

credit

exposure.

The

are

different

from,

and

potentially

much

greater

than,

the

risks

associated

with

investing

directly

in

the

instruments

on

which

the

are

The

fund

values

its

derivatives

at

fair

value

and

recognizes

changes

in

fair

currently

in

its

results

of

operations.

Accordingly,

the

fund

does

not

hedge

accounting,

even

for

derivatives

employed

as

economic

hedges.

Generally,

the

fund

accounts

for

its

derivatives

on

a

It

does

not

the

Counterparty

Risk

and

Collateral

 The

fund

invests

in

exchange-traded

and/or

centrally

cleared

derivative

contracts,

such

as

futures,

exchange-traded

options,

and

centrally

cleared

swaps.

Counterparty

risk

on

such

derivatives

is

minimal

because

the

clearinghouse

provides

protection

against

counterparty

defaults.

For

futures

and

centrally

cleared

swaps,

the

fund

is

required

to

deposit

collateral

in

an

amount

specified

by

the

clearinghouse

and

the

clearing

firm

(margin

requirement),

and

the

margin

requirement

must

be

maintained

over

the

life

of

the

contract.

Each

clearinghouse

and

clearing

firm,

in

its

sole

discretion,

may

adjust

the

margin

requirements

applicable

to

the

fund.

Collateral may

be

in

the

form

of

cash

or

debt

securities

issued

by

the

U.S.

government

or

related

agencies.

Cash

posted

by

the

fund

is

reflected

as

cash

deposits

in

the

accompanying

financial

statements

and

generally

is

restricted

from

withdrawal

by

the

fund;

securities

posted

by

the

fund

are

so

noted

in

the

accompanying

Portfolio

of

Investments;

both

remain

in

the

fund’s

assets.

While

typically

not

sold

in

the

same

manner

as

equity

or

fixed

income

securities,

exchange-traded

or

centrally

cleared

derivatives

may

be

closed

out

only

on

the

exchange

or

clearinghouse

where

the

contracts

were

cleared.

This

ability

is

subject

to

the

liquidity

of

underlying

positions. As

of

June

30,

2023,

securities

valued

at $31,000

had

been

posted

by

the

fund

for

exchange-

traded

and/or

centrally

cleared

derivatives. 

Futures

Contracts

 The

fund

is

subject

to equity

price

risk in

the

normal

course

of

pursuing

its

investment

objectives

and

uses

futures

contracts

to

help

manage

such

risk.

The

fund

may

enter

into

futures

contracts

as

an

efficient

means

of

maintaining

liquidity

while

being

invested

in

the

market,

to

facilitate

trading,

or

to

reduce

transaction

costs. A

futures

contract

provides

for

the

future

sale

by

one

party

and

purchase

by

another

of

a

specified

amount

of

a

specific

underlying

financial

instrument

at

an

agreed-upon

price,

date,

time,

and

place.

The

fund

currently

invests

only

in

exchange-traded

futures,

which

generally

are

standardized

as

OTHER

INVESTMENT

TRANSACTIONS 

Consistent

with

its

investment

objective,

the

fund

engages

in

the

following

practices

to

manage

exposure

to

certain

risks

and/or

to

enhance

performance.

The

investment

objective,

policies,

program,

and

risk

factors

of

the

fund

are

described

more

fully

in

the

fund's

prospectus

and

Statement

of

Additional

Information.

Securities

Lending

 The fund

may

lend

its

securities

to

approved

borrowers

to

earn

additional

income.

Its

securities

lending

activities

are

administered

by

a

lending

agent

in

accordance

with

a

securities

lending

agreement.

Security

loans

generally

do

not

have

stated

maturity

dates,

and

the

fund

may

recall

a

security

at

any

time.

The

fund

receives

collateral

in

the

form

of

cash

or

U.S.

government

securities.

Collateral

is

maintained

over

the

life

of

the

loan

in

an

amount

not

less

than

the

value

of

loaned

securities;

any

additional

collateral

required

due

to

changes

in

security

values

is

delivered

to

the

fund

the

next

business

day.

Cash

collateral

is

invested

in

accordance

with

investment

guidelines

approved

by

fund

management.

Additionally,

the

lending

agent

indemnifies

the

fund

against

losses

resulting

from

borrower

default.

Although

risk

is

mitigated

by

the

collateral

and

indemnification,

the

fund

could

experience

a

delay

in

recovering

its

securities

and

a

possible

loss

of

income

or

value

if

the

borrower

fails

to

return

the

securities,

collateral

investments

decline

in

value,

and

the

lending

agent

fails

to

perform.

Securities

lending

revenue

consists

of

earnings

on

invested

collateral

and

borrowing

fees,

net

of

any

rebates

to

the

borrower,

compensation

to

the

lending

agent,

and

other

administrative

costs.

In

Since

2020,

a

strain

of

coronavirus

(COVID-19)

has

resulted

in

disruptions

to

global

business

activity

and

caused

significant

volatility

and

declines

in

global

financial

markets.

In

February

2022,

Russian

forces

entered

Ukraine

and

commenced

an

armed

conflict

leading

to

economic

sanctions

being

imposed

on

Russia

and

certain

of

its

citizens,

creating

impacts

on

Russian-related

and

debt

and

greater

volatility

in

global

markets.

In

March

2023,

the

collapse

of

some

US

regional

and

global

banks

as

well

as

overall

concerns

around

the

soundness

and

stability

of

the

global

banking

sector

has

sparked

concerns

of

a

broader

crisis

impacting

the

sector.

In

certain

cases,

government

agencies

have

assumed

control

or

otherwise

intervened

in

the

operations

of

certain

due

to

liquidity

and

solvency

concerns.

The

extent

of

impact

of

these

events

on

the

US

is

highly

uncertain.

These

APPROVAL

OF

INVESTMENT

MANAGEMENT

AGREEMENT

AND

SUBADVISORY

AGREEMENT

Each

year,

the

fund’s

Board

of

Directors

(Board)

considers

the

continuation

of

the

investment

management

agreement

(Advisory

Contract)

between

the

fund

and

its

investment

adviser,

T.

Rowe

Price

Associates,

Inc.

(Adviser),

as

well

as

the

investment

subadvisory

agreement

(Subadvisory

Contract)

that

the

Adviser

has

entered

into

with

T.

Rowe

Price

International

Ltd

(Subadviser)

on

behalf

of

the

fund.

In

that

regard,

at

a

meeting

held

on

March

6–7,

2023

(Meeting),

the

Board,

including

all

of

the

fund’s

independent

directors,

approved

the

continuation

of

the

fund’s

Advisory

Contract

and

Subadvisory

Contract.

At

the

Meeting,

the

Board

considered

the

factors

and

reached

the

conclusions

described

below

relating

to

the

selection

of

the

Adviser

and

Subadviser

and

the

approval

of

the

Advisory

Contract

and

Subadvisory

Contract.

The

independent

directors

were

assisted

in

their

evaluation

of

the

Advisory

Contract

and

Subadvisory

Contract

by

independent

legal

counsel

from

whom

they

received

separate

legal

advice

and

with

whom

they

met

separately.

In

providing

information

to

the

Board,

the

Adviser

was

guided

by

a

detailed

set

of

requests

for

information

submitted

by

independent

legal

counsel

on

behalf

of

the

independent

directors.

In

considering

and

approving

the

continuation

of

the

Advisory

Contract

and

Subadvisory

Contract,

the

Board

considered

the

information

it

believed

was

relevant,

including,

but

not

limited

to,

the

information

discussed

below.

The

Board

considered

not

only

the

specific

information

presented

in

connection

with

the

Meeting

but

also

the

knowledge

gained

over

time

through

interaction

with

the

Adviser

and

Subadviser

about

various

topics.

The

Board

meets

regularly

and,

at

each

of

its

meetings,

covers

an

extensive

agenda

of

topics

and

materials

and

considers

factors

that

are

relevant

to

its

annual

consideration

of

the

renewal

of

the

T.

Rowe

Price

funds’

advisory

contracts,

including

performance

and

the

services

and

support

provided

to

the

funds

and

their

shareholders.

Services

Provided

by

the

Adviser

and

Subadviser

The

Board

considered

the

nature,

quality,

and

extent

of

the

services

provided

to

the

fund

by

the

Adviser

and

Subadviser.

These

services

included,

but

were

not

limited

to,

directing

the

fund’s

investments

in

accordance

with

its

investment

program

and

the

overall

management

of

the

fund’s

portfolio,

as

well

as

a

variety

of

related

activities

such

as

financial,

investment

operations,

and

administrative

services;

compliance;

maintaining

the

fund’s

records

and

registrations;

and

shareholder

communications.

The

Board

also

reviewed

the

background

and

experience

of

the

Adviser’s

and

Subadviser’s

senior

management

teams

and

investment

personnel

involved

in

the

management

of

the

fund,

as

well

as

the

Adviser’s

compliance

record.

The

Board

concluded

that

the

information

it

considered

with

respect

to

the

nature,

quality,

and

extent

of

the

services

provided

by

the

Adviser

and

Subadviser,

as

well

as

the

other

factors

considered

at

the

Meeting,

supported

the

Board’s

approval

of

Investment

Performance

of

the

The

Board

took

into

account

discussions

with

the

Adviser

and

detailed

reports

that

it

regularly

receives

throughout

the

year

on

relative

and

absolute

performance

for

the

T.

funds.

In

connection

with

the

Meeting,

the

Board

reviewed

information

provided

by

the

Adviser

that

compared

the

fund’s

total

returns,

as

well

as

a

wide

variety

of

other

previously

agreed-upon

performance

measures

and

market

data,

against

relevant

benchmark

indexes

and

peer

groups

of

funds

with

similar

investment

programs

for

various

periods

through

December

31,

2022. Additionally,

the

Board

reviewed

the

fund’s

relative

performance

information

as

of

September

30,

2022,

which

ranked

the

returns

of

the

fund’s

Investor

for

various

periods

against

a

universe

of

funds

with

similar

investment

programs

selected

by

Broadridge,

an

independent

provider

of

mutual

fund

data.

In

the

course

of

its

deliberations,

the

Board

considered

performance

information

provided

throughout

the

year

and

in

connection

with

the

Advisory

Contract

review

at

the

Meeting,

as

well

as

information

provided

during

investment

review

meetings

conducted

with

portfolio

managers

and

senior

investment

personnel

during

the

course

of

the

year

regarding

the

fund’s

performance.

The

Board

also

considered

relevant

factors,

such

as

overall

market

conditions

and

trends

that

could

adversely

impact

the

fund’s

performance,

length

of

the

fund’s

performance

track

record,

and

how

closely

the

fund’s

strategies

align

with

its

benchmarks

and

peer

groups.

The

Board

concluded

that

the

information

it

considered

with

respect

to

the

fund’s

performance,

as

well

as

the

other

factors

considered

at

the

Meeting,

supported

the

Board’s

approval

of

the

continuation

of

the

Advisory

Contract

and

Subadvisory

Contract.

Costs,

Benefits,

Profits,

and

Economies

of

Scale

The

Board

reviewed

detailed

information

regarding

the

revenues

received

by

the

Adviser

under

the

Advisory

Contract

and

other

direct

and

indirect

benefits

that

the

Adviser

(and

its

affiliates)

may

have

realized

from

its

relationship

with

the

fund.

In

considering

soft-

dollar

arrangements

pursuant

to

which

research

may

be

received

from

broker-dealers

that

execute

the

fund’s

portfolio

transactions,

the

Board

noted

that

the

Adviser

bears

the

cost

of

research

services

for

all

client

accounts

that

it

advises,

including

the

T.

Rowe

Price

funds.

The

Board

received

information

on

the

estimated

costs

incurred

and

profits

realized

by

the

Adviser

from

managing

the

T.

Rowe

Price

funds.

While

the

Board

did

not

review

information

regarding

profits

realized

from

managing

the

fund

in

particular

because

the

fund

had

either

not

achieved

sufficient

portfolio

asset

size

or

not

recognized

sufficient

revenues

to

produce

meaningful

profit

margin

percentages,

the

Board

concluded

that

the

Adviser’s

profits

were

reasonable

in

light

of

the

services

provided

to

the

T.

Price

funds.

The

Board

also

considered

whether

the

fund

benefits

under

the

fee

levels

set

forth

in

the

Advisory

Contract

or

otherwise

from

any

economies

of

scale

realized

by

the

Adviser.

Under

the

Advisory

Contract,

the

fund

pays

a

fee

to

the

Adviser

for

investment

management

services

based

on

the

fund’s

average

daily

net

assets

and

the

fund

pays

its

own

expenses

of

operations.

Under

the

Subadvisory

Contract,

the

Adviser

may

pay

the

Subadviser

up

to

60%

of

the

advisory

fees

that

the

Adviser

receives

from

the

fund.

The

fund’s

shareholders

have

benefited

from

economies

of

scale

through

reductions

to

the

fund’s

management

fee,

and

the

fund

is

also

subject

to

contractual

expense

limitations

that

require

the

fund

to

waive

its

fees

and/or

bear

any

expenses

that

would

otherwise

cause

the

expenses

of

a

share

class

of

the

fund

to

exceed

a

certain

percentage

based

on

the

class’s

net

assets.

The

expense

limitations

mitigate

the

potential

for

relatively

higher

expenses

until

the

fund

achieves

greater

scale.

The

fund

also

offers

a

Z

Class,

which

serves

as

an

underlying

investment

within

certain

T.

Rowe

Price

fund

of

funds

arrangements.

The

Adviser

waives

its

advisory

fee

on

the

Z

Class

and

waives

or

bears

the

Z

Class’s

other

operating

expenses,

with

certain

exceptions.

The

Board

considered

whether

the

advisory

fee

and

operating

expense

waivers

on

the

Z

Class

may

present

a

means

for

cross-subsidization

of

the

Z

Class

by

other

share

classes

of

the

fund.

In

that

regard,

the

Board

noted

that

the

Z

Class

operating

expenses

are

largely

covered

by

the

all-inclusive

fees

charged

by

the

investing

T.

Rowe

Price

fund

of

funds

and

that

any

Z

Class

operating

expenses

not

covered

by

the

investing

T.

Rowe

Price

fund

of

funds’

fees

are

paid

by

the

Adviser

and

not

by

shareholders

of

any

other

share

class

of

the

fund.

In

addition,

the

Board

noted

that

the

fund

potentially

shares

in

indirect

economies

of

scale

through

the

Adviser’s

ongoing

investments

in

its

business

in

support

of

the

T.

Rowe

Price

funds,

including

investments

in

trading

systems,

technology,

and

regulatory

support

enhancements,

and

the

ability

to

possibly

negotiate

lower

fee

arrangements

with

third-

party

service

providers.

The

Board

concluded

that

the

advisory

fee

structure

for

the

fund

provides

for

a

reasonable

sharing

of

benefits

from

any

economies

of

scale

with

the

fund’s

investors.

Fees

and

Expenses

The

Board

was

provided

with

information

regarding

industry

trends

in

management

fees

and

expenses.

Among

other

things,

the

Board

reviewed

data

for

peer

groups

that

were

compiled

by

Broadridge,

which

compared:

(i)

contractual

management

fees,

actual

management

fees,

nonmanagement

and

total

of

the

of

the

in

with

the

information

for

Broadridge

generally

constructed

the

peer

groups

by

seeking

the

most

comparable

funds

based

on

similar

investment

classifications

and

objectives,

expense

structure,

asset

size,

and

operating

components

and

attributes

and

ranked

funds

into

quintiles,

with

the

first

representing

the

funds

with

the

lowest

relative

expenses

and

the

fifth

quintile

representing

the

funds

with

the

highest

relative

expenses.

The

information

provided

to

the

Board

indicated

that

the

fund’s

contractual

management

fee

ranked

in

the

first

quintile

(Expense

the

fund’s

actual

rate

ranked

and

the

ranked

in

the

second

and

third

The

Board

also

reviewed

the

fee

schedules

for

other

investment

portfolios

with

similar

mandates

that

are

advised

or

subadvised

by

the

Adviser

and

its

affiliates,

including

separately

managed

accounts

for

institutional

and

individual

investors;

subadvised

funds;

and

other

sponsored

investment

portfolios,

including

collective

investment

trusts

and

pooled

vehicles

organized

and

offered

to

investors

outside

United

Management

provided

the

Board

with

information

about

the

Adviser’s

responsibilities

and

services

provided

to

subadvisory

and

other

institutional

account

clients,

including

information

about

how

the

requirements

and

economics

of

the

institutional

business

are

fundamentally

different

from

those

of

the

proprietary

mutual

fund

business.

The

Board

considered

information

showing

that

the

Adviser’s

mutual

fund

business

is

generally

more

complex

from

a

business

and

compliance

perspective

than

its

institutional

account

business

and

considered

various

relevant

factors,

such

as

the

broader

scope

of

operations

and

oversight,

more

extensive

shareholder

communication

infrastructure,

greater

asset

flows,

heightened

business

risks,

and

differences

in

applicable

laws

and

regulations

associated

with

the

Adviser’s

proprietary

mutual

fund

business.

In

assessing

the

reasonableness

of

the

fund’s

management

fee

rate,

the

Board

considered

the

differences

in

the

nature

of

the

services

required

for

the

Adviser

to

manage

its

mutual

fund

business

versus

managing

a

discrete

pool

of

assets

as

a

subadviser

to

another

institution’s

mutual

fund

or

for

an

institutional

account

and

that

the

Adviser

generally

performs

significant

additional

services

and

assumes

greater

risk

in

managing

the

fund

and

other

T.

Rowe

Price

funds

than

it

does

for

institutional

account

clients,

including

subadvised

On

the

basis

of

the

information

provided

and

the

factors

considered,

the

Board

concluded

that

the

fees

paid

by

the

fund

under

the

are

reasonable.
