of

Directors

(the

has

designated

T.

as

the

fund’s

valuation

designee

(Valuation

Designee).

Subject

to

oversight

by

the

Board,

the

Valuation

Designee

performs

the

following

functions

in

performing

fair

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)

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

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.

Valuation

Techniques 

Equity

securities,

including

exchange-traded

funds, listed

or

regularly

traded

on

a

securities

exchange

or

in

the

over-the-counter

(OTC)

market

are

valued

at

the

last

quoted

sale

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

share

on

the

day

of

valuation.

Futures

contracts

are

valued

at

closing

settlement

prices.

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

T.

PRICE

Small-Cap

Index

Fund

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

market

value

of

a

similar,

freely

traded

security

of

the

same

issuer;

discounted

cash

flows;

yield

to

maturity;

or

some

combination.

Fair

value

determinations

are

reviewed

on

a

regular

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

Valuation

Designee could

differ

from

those

of

other

market

participants,

and

it

is

possible

that

the

fair

value

determined

for

a

security

may

be

materially

different

from

the

value

that

could

be

realized

upon

the

sale

of

that

security.

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

monitoring

the

risks

and

financial

impacts

arising

from

these

events.
