## What drove fund performance during the past 12 months?
* Small-cap U.S. stocks produced strong gains in 2025. After a challenging start to the year stemming from new U.S. tariffs, equities advanced as economic growth and corporate earnings remained favorable, investors favored artificial intelligence-related and other high-growth businesses, and Congress passed tax legislation that should help stimulate the economy. In addition, signs of a weakening labor market prompted the Federal Reserve to resume reducing short-term interest rates in the latter part of the year. The central bank lowered rates in September, October, and December. 

* Health care names produced robust results during the period, as biotechnology firms drove absolute returns. BridgeBio Pharma and Insmed were the top performers in the segment. Industrials and business services also contributed to returns; aerospace and defense companies performed particularly well. 

* Conversely, energy detracted from absolute returns the most during the reporting period, albeit modestly. Energy equipment and services names hurt the most, with Cactus performing worst. Consumer staples detracted to a lesser extent, as food products companies performed poorly. 

* The fund, which is not available for direct purchase by members of the public, employs a full replication strategy, which involves investing substantially all of its assets in all of the stocks in the index and seeking to maintain holdings of each stock in proportion to its weight in the Russell 2000 Index. By replicating the structure of the index, our intention is to closely track its performance.

The preceding line graph shows the value of a hypothetical $10,000 investment in the fund over the past 10 fiscal year periods or since inception (for funds lacking 10-year records). The fund's performance information included in the line graph and table above is compared with a regulatory required index that represents an overall securities market (Regulatory Benchmark). In addition, the line graph and table may also include one or more indexes that more closely aligns to the fund's investment strategy (Strategy Benchmark(s)). The fund's total return figures reflect the reinvestment of dividends and capital gains, if any.Neither the fund's returns nor the index returns reflect the deduction of taxes that a shareholder would pay on fund distributions or redemptions of fund shares.**The fund's past performance is not a good predictor of the fund's future performance.**Updated performance information can be found at www.troweprice.com.

------

#### Item 1. (b) Notice pursuant to Rule 30e-3.
Not applicable.

#### Item 2. Code of Ethics.
The registrant has adopted a code of ethics, as defined in Item 2 of Form N-CSR, applicable to its principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of this code of ethics is filed as an exhibit to this Form N-CSR. No substantive amendments were approved or waivers were granted to this code of ethics during the period covered by this report.

#### Item 3. Audit Committee Financial Expert.
The registrant's Board of Directors has determined that Mr. Paul F. McBride qualifies as an audit committee financial expert, as defined in Item 3 of Form N-CSR. Mr. McBride is considered independent for purposes of Item 3 of Form N-CSR.

#### Item 4. Principal Accountant Fees and Services.
(a) – (d) Aggregate fees billed for the last two fiscal years for professional services rendered to, or on behalf of, the registrant by the registrant's principal accountant were as follows:

---

| | | |
|:---|:---|:---|
|  | <u>2025</u> | <u>2024</u> |
|  Audit Fees | $23735 | $23525 |
|  Audit-Related Fees |  |  |
|  Tax Fees | 125 |  |
|  All Other Fees |  |  |

---

Audit fees include amounts related to the audit of the registrant's annual financial statements and services normally provided by the accountant in connection with statutory and regulatory filings. Audit-related fees include amounts reasonably related to the performance of the audit of the registrant's financial statements and specifically include the issuance of a report on internal controls and, if applicable, agreed-upon procedures related to fund acquisitions. Tax fees include amounts related to services for tax compliance, tax planning, and tax advice. The nature of these services specifically includes the review of distribution calculations and the preparation of Federal, state, and excise tax returns. All other fees include the registrant's pro-rata share of amounts for agreed-upon procedures in conjunction with service contract approvals by the registrant's Board of Directors/Trustees.

(e)(1) The registrant's audit committee has adopted a policy whereby audit and non-audit services performed by the registrant's principal accountant for the registrant, its investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant require pre-approval in advance at regularly scheduled audit committee meetings. If such a service is required between regularly scheduled audit committee meetings, pre-approval may be authorized by one audit committee member with ratification at the next scheduled audit committee meeting. Waiver of pre-approval for audit or non-audit services requiring fees of a de minimis amount is not permitted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) No services included in (b) – (d) above were approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

(f) Less than 50 percent of the hours expended on the principal accountant's engagement to audit the registrant's financial statements for the most recent fiscal year were attributed to work performed by persons other than the principal accountant's full-time, permanent employees.

(g) The aggregate fees billed for the most recent fiscal year and the preceding fiscal year by the registrant's principal accountant for non-audit services rendered to the registrant, its investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant were $1,862,000 and $1,262,000, respectively.

(h) All non-audit services rendered in (g) above were pre-approved by the registrant's audit committee. Accordingly, these services were considered by the registrant's audit committee in maintaining the principal accountant's independence.

(i) Not applicable.

(j) Not applicable.

#### Item 5. Audit Committee of Listed Registrants.
Not applicable.

#### Item 6. Investments.
(a) Not applicable. The complete schedule of investments is included in Item 7 of this Form N-CSR.

(b) Not applicable.

#### Item 7. Financial Statements and Financial Highlights for Open-End Management Investment Companies.
(a – b) Report pursuant to Regulation S-X.

T. Rowe

Price

Index

Trust,

Inc. (the

corporation)

is

registered

under

the

Investment

Company

Act

of

1940

(the

1940

Act).

The

Small-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

small-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

Small-Cap

Fund

(Investor

Class),

the

Small-Cap

Index

Fund–I

Class

(I

Class)

and

the

Small-Cap

Index

Fund–Z

Class

(Z

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

respects,

the

same

rights

are

reported

on

the

#### Capital

#### Transactions
Each

of

the

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

p.m.

Eastern

time,

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

order

by

T. Rowe

#### Indemnification
In

of

business, the

may

provide

with

its

officers

and

directors,

service

maximum

exposure

under

&nbsp;&nbsp;&nbsp;&nbsp;The

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

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

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

–

quoted

prices

(unadjusted)

in

active

markets

for

identical

financial

instruments

that

the

fund

can

access

at

the

reporting

date

Level

inputs

other

than

Level

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

–

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

Input

levels

are

not

necessarily

an

indication

of

the

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

the

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

#### DERIVATIVE

#### INSTRUMENTS
During

the

year ended

December

31,

2025,

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

or

delivery

of

cash

or

other

assets.

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.

greater

than,

the

risks

associated

with

investing

directly

in

the

instruments

on

which

the

are

based.

The

fund

values

its

derivatives

at

fair

value

and

recognizes

changes

in

fair

value

currently

in

its

results

of

operations.

Accordingly,

the

fund

does

not

follow

hedge

accounting,

even

for

derivatives

employed

as

economic

hedges.

Generally,

the

fund

accounts

for

its

derivatives

on

a

gross

basis.

It

does

not

offset

the

fair

value

of

derivative

liabilities

against

the

fair

value

of

nor

Fund

#### Counterparty

#### Risk

#### 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

in

the

accompanying

financial

statements

and

generally

is

restricted

from

withdrawal

by

the

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

December

31,

2025,

cash

of $191,000 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

The

fund

currently

invests

only

in

exchange-traded

futures,

which

generally

are

standardized

as

to

maturity

financial

instrument,

and

enhance

performance.

#### 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

## Ex-99.Code

**CODE OF ETHICS FOR PRINCIPAL EXECUTIVE AND SENIOR FINANCIAL OFFICERS** 

**OF THE T. ROWE PRICE MUTUAL FUNDS AND EXCHANGE-TRADED FUNDS** 

**UNDER THE SARBANES-OXLEY ACT OF 2002** 

**I.**  **<u>INTRODUCTORY NOTE</u>** 

**A.** **General Statement.** 

This Code of Ethics for the T. Rowe Price Mutual Funds and Exchange-Traded Funds (the "Price ETFs" and, together with the Mutual Funds, the **"Price Funds"**) has been designed to bring the Price Funds into compliance with the applicable requirements of the Sarbanes-Oxley Act of 2002 (the **"Act"**) and rules promulgated by the Securities and Exchange Commission thereunder (**"Regulations"**). This Price Funds' Code of Ethics (the **"S-O Code"**) applies solely to the Principal Executive Officer, Principal Financial Officer, Principal Accounting Officer or Controller of, or persons performing similar functions for, a Price Fund (whether such persons are employed by a Price Fund or third party) (**"Covered Officers"**). The **"Price Funds"** shall include each mutual fund and ETF that is managed, sponsored and distributed by affiliates of T. Rowe Price Group, Inc. (**"Group"**). The investment managers to the Price Funds will be referred to as the **"Price Fund Advisers**.**"** A list of Covered Officers is attached as **Exhibit A**.

The Price Fund Advisers have, along with their parent, Group also maintained a comprehensive Global Code of Conduct (the **"Code of Conduct"**) and a Code of Ethics and Personal Transactions Policy (the "**Group Code**") since 1972, which applies to all officers, directors and employees of the Price Funds, Group and its affiliates.

As mandated by the Act, Group has adopted a Code of Ethics for Principal Executive and Senior Financial Officers (the "**Group S-O Code**"), similar to the Price Funds S-O Code, which applies solely to its principal executive and senior financial officers. The Group S-O Code and the Price Funds S-O Code will be referred to collectively as the "**S-O Codes**".

The Price Funds S-O Code has been adopted by the Price Funds in accordance with the Act and Regulations thereunder and will be administered in conformity with the disclosure requirements of Item 2 of Form N-CSR. The S-O Codes are attachments to the Group Code. In many respects the S-O Codes are supplementary to the Group Code, but the Group Code is administered separately from the S-O Codes, as the S-O Codes are from each other.

***The Introductory Note is a summary and should not be considered a substitute for reading and understanding the entire Policy. Associates must be familiar with all of their responsibilities under the Policy. Please refer to Section VI below for a list of the applicable rules/regulations. Capitalized terms are defined in Section IV. Capitalized terms not otherwise defined herein shall have the meaning ascribed to them under the Glossary.***

**II.**  **<u>POLICY</u>** 

**Purpose of the Price Funds S-O Code.** 

The purpose of the Price Funds S-O Code, as mandated by the Act and the Regulations, is to establish

------

standards that are reasonably designed to deter wrongdoing and to promote:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Ethical Conduct.** Honest and ethical conduct, including the ethical handling of actual or apparent conflicts of
interest between personal and professional relationships.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Disclosure.** Full, fair, accurate, timely and understandable disclosure in reports and documents that the Price
Funds file with, or submit to, the SEC and in other public communications made by the Price Funds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Compliance.** Compliance with applicable governmental laws, rules and regulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Reporting of Violations.** The prompt internal reporting of violations of the Price Funds S-O Code to an appropriate person or persons identified in the Price Funds S-O Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Accountability.** Accountability for adherence to the Price Funds S-O Code.

**A.** **Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest.** 

**Overview.** 

Each Covered Officer owes a duty to the Price Funds to adhere to a high standard of honesty and business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

A "conflict of interest" occurs when a Covered Officer's private interest interferes with the interests of, or his or her service to, the Price Funds. For example, a conflict of interest would arise if a Covered Officer, or a member of his or her family, receives improper personal benefits as a result of his or her position with a Price Fund.

Certain conflicts of interest covered by the Price Funds S-O Code arise out of the relationships between Covered Officers and the Price Funds and may already be subject to provisions regulating conflicts of interest in the Investment Company Act of 1940 (**"Investment Company Act"**), the Investment Advisers Act of 1940 (**"Investment Advisers Act"**) and the Group Code. For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with a Price Fund because of their status as "affiliated persons" of a Price Fund. The compliance programs and procedures of the Price Funds and Price Fund Advisers are designed to prevent, or identify and correct, violations of these provisions.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between a Price Fund and its Price Fund Adviser (and its affiliates) of which the Covered Officers may also be officers or employees. As a result, the Price Funds S-O Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Price Funds or for the Price Fund Advisers, or for both), be involved in establishing policies and implementing decisions which will have different effects on these entities. The participation of the Covered Officers in such activities is inherent in the contractual relationship between each Price Fund and its respective Price Fund Adviser. Such participation is also consistent with the performance by the Covered Officers of their duties as officers of the Price Funds and, if consistent with the provisions of the Investment Company Act and the Investment Advisers Act, it will be deemed to have been handled ethically.

------

Other conflicts of interest are covered by the Price Funds and Price ETFs S-O Code, even if these conflicts of interest are not addressed by or subject to provisions in the Investment Company Act and the Investment Advisers Act.

Whenever a Covered Officer is confronted with a conflict of interest situation where he or she is uncertain as to the appropriate action to be taken, he or she should discuss the matter with the Chairperson of Group's Ethics Committee or another member of the Committee.

**III.**  **<u>PROCEDURES</u>** 

**A.** **Handling of Specific Types of Conflicts.** 

Each Covered Officer (and close family members) must not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Entertainment.** 

Accept entertainment from any company with which any Price Fund or any Price Fund Adviser has current or prospective business dealings including portfolio companies, unless such entertainment is in full compliance with the policy on entertainment as set forth in the Group Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Gifts.** 

Accept any gifts, except as permitted by the Group Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Improper Personal Influence.** 

Use his or her personal influence or personal relationships improperly to influence investment decisions, brokerage allocations or financial reporting by the Price Funds to the detriment of any one or more of the Price Funds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Taking Action at the Expense of a Price Fund.** 

Cause a Price Fund to take action, or fail to take action, for the personal benefit of the Covered Officer rather than for the benefit of one or more of the Price Funds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Misuse of Price Funds' Transaction Information.** 

Use knowledge of portfolio transactions made or contemplated for a Price Fund or any other clients of the Price Fund Advisers to trade personally or cause others to trade in order to take advantage of or avoid the market impact of such portfolio transactions; and in connection with Price ETFs that do not disclose portfolio holdings daily, use knowledge of pending changes to an ETF's proxy portfolio holdings for such purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Outside Business Activities.** 

Engage in any outside business activity that detracts from a Covered Officer's ability to devote appropriate time and attention to his or her responsibilities to a Price Fund.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Service Providers.** 

Excluding Group and its affiliates, have any ownership interest in, or any consulting or employment relationship with, any of the Price Funds' service providers, except that an ownership interest in public companies is permitted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Receipt of Payments.** 

Have a direct or indirect financial interest in commissions, transaction charges, spreads or other payments paid by a Price Fund for effecting portfolio transactions or for selling or redeeming shares other than an interest (such as compensation or equity ownership) arising from the Covered Officer's employment by Group or any of its affiliates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Service as a Director or Trustee.** 

Serve as a director, trustee or officer of any public or private company or a non-profit organization that issues securities eligible for purchase by any of the Price Funds, unless approval is obtained as required by the Group Code.

**B.** **Covered Officers' Specific Obligations and Accountabilities.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Disclosure Requirements and Controls.** 

Each Covered Officer must familiarize himself or herself with the disclosure requirements (Form N-lA registration statement, proxy (Schedule 14A), shareholder reports, Forms N-CEN, N-CSR, etc.) applicable to the Price Funds and the disclosure controls and procedures of the Price Fund and the Price Fund Advisers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Compliance with Applicable Law.** 

It is the responsibility of each Covered Officer to promote compliance with all laws, rules and regulations applicable to the Price Funds and the Price Fund Advisers. Each Covered Officer should, to the extent appropriate within his or her area of responsibility, consult with other officers and employees of the Price Funds and the Price Fund Advisers and take other appropriate steps with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Price Funds file with, or submit to, the SEC, and in other public communications made by the Price Funds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Fair Disclosure.** 

Each Covered Officer must not knowingly misrepresent, or cause others to misrepresent, facts about a Price Fund to others, whether within or outside the Price organization, including to the Price Fund's directors and auditors, and to governmental regulators and self-regulatory organizations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.** **Initial and Annual Affirmations. Each Covered Officer must:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Upon adoption of the Price Funds S-O Code (or thereafter, as applicable,
upon becoming a Covered Officer), affirm in writing that he or she has received, read, and understands the Price Funds S-O Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Annually affirm that he or she has complied with requirements of the Price Funds S-O Code.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.** **Reporting of Material Violations of the Price Funds S-O Code.** 

If a Covered Officer becomes aware of any material violation of the Price Funds S-O Code or laws and governmental rules and regulations applicable to the operations of the Price Funds, he or she must promptly report the violation (**"Report"**) to the Chief Compliance Officer of the Price Funds (**"CCO"**). Failure to report a material violation will be considered itself a violation of the Price Funds S-O Code. The CCO is identified in the attached **Exhibit B**.

It is the Price Funds' policy that no retaliation or other adverse action will be taken against any Covered Officer or other employee of a Price Fund, a Price Fund Adviser or their affiliates based upon any lawful actions of the Covered Officer or employee with respect to a Report made in good faith.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.** **Annual Disclosures.** 

Each Covered Officer must report, at least annually, all affiliations or other relationships as called for in the "Annual Compliance Certification" for Group.

**C.** **Administration of the Price Funds S-O Code.** 

The Ethics Committee is responsible for administering the Price Funds S-O Code and applying its provisions to specific situations in which questions are presented.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.** **Waivers and Interpretations.** The Chairperson of the Ethics Committee has the authority to interpret the Price
Funds S-O Code in any particular situation and to grant waivers where justified, subject to the approval of the Joint Audit Committee of the Price Funds. All material interpretations concerning Covered
Officers will be reported to the Joint Audit Committee of the Price Funds at its next meeting. Waivers, including implicit waivers, to Covered Officers will be publicly disclosed as required in the Instructions to N-CSR. Pursuant to the definition in the Regulations, an implicit waiver means a Price Fund's failure to take action within a reasonable period of time regarding a material departure from a provision of
the Price Funds S-O Code that has been made known to an "executive officer" (as defined in Rule 3b-7 under the Securities Exchange Act of 1934) of a Price
Fund. An executive officer of a Price Fund includes its president and any vice-president in charge of a principal business unit, division or function.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.** **Violations/Investigations.** The following procedures will be followed in investigating and enforcing the Price
Funds S-O Code:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The CCO will take or cause to be taken appropriate action to investigate any potential or actual violation reported
to him or her.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The CCO, after consultation if deemed appropriate with Outside Counsel to the Price Funds, will make a
recommendation to the appropriate Price Funds Board regarding

------

the action to be taken with regard to each material violation. Such action could include any of the following: a letter of censure or suspension, a fine, a suspension of trading privileges or termination of officership or employment. In addition, the violator may be required to surrender any profit realized (or loss avoided) from any activity that is in violation of the Price Funds S-O Code. <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Investigations of Whistleblower complaints related to Price Funds will be handled in accordance with the T. Rowe
Price Global Whistleblower Policy.

**D. Amendments to the Price Funds S-O Code.** Except as to the contents of **Exhibit A and Exhibit B**, the Price Funds S-O Code may not be materially amended except in written form, which is specifically approved or ratified by a majority vote of each Price Fund Board, including a majority of the independent directors on each Board.

**E. Confidentiality.** All reports and records prepared or maintained pursuant to the Price Funds S-O Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law, the Price Funds S-O Code or as necessary in connection with regulations under the Price Funds S-O Code, such matters shall not be disclosed to anyone other than the directors of the appropriate Price Fund Board, Outside Counsel to the Price Funds, members of the Ethics Committee and the CCO and authorized persons on his or her staff.
