Price
Index
Trust,
Inc. (the
corporation) is
registered
under
the
Investment
Company
Act
of
1940
(the
1940
Act).
The
Mid-Cap
Index
Fund
(the
fund)
is
an
open-end
management
investment
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
mid-
capitalization
U.S.
stocks.
The
fund
is
available
for
investment
only
by
mutual
funds,
college
savings
plans,
and
other
institutional
client
accounts
managed
by
T.
Rowe
Price
Associates,
Inc.,
or
its
affiliates
and
is
not
available
for
direct
purchase
by
members
of
the
public.
The
fund
has three classes
of
shares:
the
Mid-Cap
Index
Fund
(Investor
Class),
the
Mid-Cap
Index
Fund–I
Class
(I
Class)
and
the
Mid-Cap
Index
Fund–Z
Class
(Z
Class).
I
Class
shares
require
a
$500,000
initial
investment
minimum,
although
the
minimum
generally
is
waived
or
reduced
for
financial
intermediaries,
eligible
retirement
plans,
and
certain
other
accounts.
The
Z
Class
is
only
available
to
funds
advised
by
T.
Rowe
Price
Associates,
Inc.
and
its
affiliates
and
other
clients
that
are
subject
to
a
contractual
fee
for
investment
management
services. Each
class
has
exclusive
voting
rights
on
matters
related
solely
to
that
class;
separate
voting
rights
on
matters
that
relate
to
all
classes;
and,
in
all
other
respects,
the
same
rights
and
obligations
as
the
other
classes.

Standards
Board
(FASB)

generally
accepted
in
the
United

of
America
(GAAP),
including,
but

GAAP
requires
the
use
of

management.
Management
believes
that
estimates

are
appropriate;
however,
actual

Capital
Transactions
Each
investor’s
interest
in
the
net

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
SEC.
Purchases
and
redemptions
of
fund
shares
are
transacted
at
the
next-computed
NAV
per
share,
after
receipt
of
the
transaction
order
by
T.
Rowe
Price
Associates,
Inc.,
or
its

Indemnification
In
the
normal
course
of
business, the
fund
may
provide
indemnification
in
connection
with
its
officers
and
directors,
service
providers,
and/or
private

investments. The
fund’s
maximum
exposure
under
these
arrangements
is
unknown;
however,

of
material
loss
is
currently
considered
to
be
remote.

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
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.
Investments
in
mutual
funds
are
valued
at
the
mutual
fund’s
closing
NAV
per
share
on
the
day
of
valuation.
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
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.

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.

the
Board
considered
the

it
believed
was

nature,
quality,
and
extent
of
the
services
provided
to

These

Investment
Performance
of
the
Fund
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.
Rowe
Price
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,
2023.
Additionally,
the
Board
reviewed
the
fund’s
relative
performance
information
as
of
September
30,
2023,
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,
the
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

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,
including
the
Subadviser)
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
during
2023
the
Adviser
paid
the
costs
of
research
services
for
all
client
accounts
that
it
advises,
including
the
T.
Rowe
Price
funds.
However,
effective
January
1,

the
Adviser
will
begin
using
brokerage
commissions
in
connection
with
certain

securities
transactions
to
pay
for
research
when
permissible.

The
Board
received
information
on
the
estimated
costs
incurred
and
profits
realized
by
the
Adviser
from
managing
the
T.
Rowe
Price
funds.
The
Board
also
reviewed
estimates
of
the
profits
realized
from
managing
the
fund
in
particular,
and
the
Board
concluded
that
the
Adviser’s
profits
were
reasonable
in
light
of
the
services
provided
to
the
fund.
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
benefit
from
potential
economies
of
scale
through
a
decline
in
certain
operating
expenses
as
the
fund
grows
in
size.
However,
the
fund
is
also
subject
to
contractual
expense
limitations
that
require
the
Adviser
to
waive
its
fees
and/or
bear
any
expenses
that
would
otherwise
cause
the
fund’s
expenses
to
exceed
a
certain
percentage
based
on
the
fund’s
net
assets.
The
expense
limitation
mitigates
the
potential
for
an
increase
in
total
operating
expenses
above
a
certain
level
that
could
impact
shareholders.
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
and
Subadviser’s
ongoing
investments
in
their
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
expenses,
and
total
expenses
of
the
Investor
Class
of
the
fund
with
a
group
of
competitor
funds
selected
by
Broadridge
(Expense
Group)
and
(ii)
actual
management
fees,
nonmanagement
expenses,
and
total
expenses
of
the
Investor
Class
of
the
fund
with
a
broader
set
of
funds
within
the
Lipper
investment
classification
(Expense
Universe).
The
Board
considered
the
fund’s
contractual
management
fee
rate,
actual
management
fee
rate
(which
reflects
the
management
fees
actually
received
from
the
fund
by
the
Adviser
after
any
applicable
waivers,
reductions,
or
reimbursements),
operating
expenses,
and
total
expenses
(which
reflect
the
net
total
expense
ratio
of
the
fund
after
any
waivers,
reductions,
or
reimbursements)
in
comparison
with
the
information
for
the
Broadridge
peer
groups.
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
quintile
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
fourth
quintile
(Expense
Group),
the
fund’s
actual
management
fee
rate
ranked
in
the
first
quintile
(Expense
Group
and
Expense
Universe),
and
the
fund’s
total
expenses
ranked
in
the
fifth
quintile
(Expense
Group
and
Expense
Universe).
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
the
United
States.
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
APPROVAL

Index

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
funds.
On
the
basis
of
the
information
provided
and
the
factors
considered,
the
Board
concluded
that
the
fees
paid
by
the
fund
under
the
Advisory
Contract
are
reasonable.
Approval
of
the
Advisory
Contract
and
Subadvisory
Contract
As
noted,
the
Board
approved
the
continuation
of
the
Advisory
Contract
and
Subadvisory
Contract.
No
single
factor
was
considered
in
isolation
or
to
be
determinative
to
the
decision.
Rather,
the
Board
concluded,
in
light
of
a
weighting
and
balancing
of
all
factors
considered,
that
it
was
in
the
best
interests
of
the

and
its
shareholders
for
the

to
approve
the
