are

valued

at

the

the

(NYSE),

normally

4

p.m.

ET,

each

day

the

NYSE

is

open

for

business,

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

Board

of

Directors

(the

Board)

has

designated

T.

Rowe

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

as

publicly

available

information

about

events

and

the

and

are

developed

using

the

best

information

available

about

the

assumptions

that

market

participants

would

use

to

price

the

financial

GAAP

requires

valuation

techniques

to

maximize

the

use

of

relevant

observable

inputs

and

minimize

the

use

of

unobservable

inputs.

When

multiple

inputs

are

used

to

derive

fair

the

is

assigned

to

the

level

within

the

fair

hierarchy

based

on

the

lowest-level

input

that

is

significant

Since

2020,

a

novel

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

stocks

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

financial

crisis

impacting

the

overall

global

banking

sector.

In

certain

cases,

government

agencies

have

assumed

control

or

otherwise

intervened

in

the

operations

of

certain

banks

due

to

liquidity

and

solvency

concerns.

The

extent

of

impact

of

these

events

on

the

US

and

global

markets

is

highly

uncertain.

These

are

recent

examples

of

global

events

which

may

have

a

negative

impact

on

the

values

of

certain

portfolio

holdings

or

the

fund’s

overall

performance.

Management

is

actively

arising
