VALUATION 
Fair
Value
  The
fund’s
financial
instruments
are
valued
at
the
close
of
the
New
York
Stock
Exchange
(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
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)
T.
ROWE
PRICE
Equity
Index
500
Fund
21
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.

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

(COVID-19)
has
resulted
in
disruptions
to
global
business
activity
and
caused

In

2022,
Russian

entered

and
commenced
an

leading
to

imposed
on
Russia

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

overall
performance.
Management
is
actively
monitoring
the
risks
and
financial
impacts
arising
