SIGNIFICANT

ACCOUNTING

POLICIES 

Basis

of

Preparation

 The fund

is

an

investment

company

and

follows

accounting

and

reporting

guidance

in

the

Financial

Accounting

Standards

Board

(FASB)

Accounting

Standards

Codification

Topic

946

(ASC

946).

The

accompanying

financial

statements

were

prepared

in

accordance

with

accounting

principles

generally

accepted

in

the

United

States

of

America

(GAAP),

including,

but

not

limited

to,

ASC

946.

GAAP

requires

the

use

of

estimates

made

by

management.

Management

believes

that

estimates

and

valuations

are

appropriate;

however,

actual

results

may

differ

from

those

estimates,

and

the

valuations

reflected

in

the

accompanying

financial

statements

may

differ

from

the

value

ultimately

realized

upon

sale

or

maturity.

Investment

Transactions,

Investment

Income,

and

Distributions

 Investment

transactions

are

accounted

for

on

the

trade

date

basis.

Income

and

expenses

are

recorded

on

the

accrual

basis.

Realized

gains

and

losses

are

reported

on

the

identified

cost

basis. Premiums

and

discounts

on

debt

securities

are

amortized

for

financial

reporting

purposes. Paydown

gains

and

losses

are

recorded

as

an

adjustment

to

interest

income. Income

tax-related

interest

and

penalties,

if

incurred,

are

recorded

as

income

tax

expense. Dividends

received

from other

investment

companies are

reflected

as

dividend income;

capital

gain

distributions

are

reflected

as

realized

gain/loss. Dividend

income and

capital

gain

distributions

are

recorded

on

the

ex-dividend

date. Non-cash

dividends,

if

any,

are

recorded

at

the

fair

market

value

of

the

asset

received. Distributions

to

shareholders

are

recorded

on

the

ex-dividend

date. Income

distributions,

if

any, are

declared daily

and

paid

monthly. A

capital

gain

distribution,

if

any, may

also

be

declared

and

paid

by

the

fund

annually.

Capital

Transactions

 Each

investor’s

interest

in

the

net

assets

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.

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

transaction

order

by

T.

Rowe

Price

Associates,

New

Accounting

Guidance

 In September

2026,

the

FASB

issued

Accounting

Standards

Update

(ASU)

ASU

2026-

03,

Fair

Value

Measurement

(Topic

820)

–

Investment

Companies

with

Equity

Securities

Subject

to

Contractual

Sale

Restrictions,

which

requires

investment

companies

within

the

scope

of

ASC

946

to

consider

contractual

sale

restrictions

on

the

sale

of

an

equity

security

when

measuring

the

fair

value

of

the

security

and

to

disclose

the

amount

of

the

discount

attributable

to

the

contractual

sale

restriction.

The

amendments

under

the

ASU

are

effective

for

fiscal

years

beginning

after

December

15,

2027;

however,

early

adoption

is

permitted.

Adoption

of

the

guidance

is

not

expected

to

have

a

material

impact

on

the

fund’s

financial

statements.

Indemnification

 In

the

normal

course

of

business, the

fund

may

provide

indemnification

in

connection

with

its

officers

and

directors,

service

providers,

and/or

private

company

investments. The

fund’s

maximum

exposure

under

these

arrangements

is

unknown;

however,

the

risk

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

T.

Rowe

Price

Mortgage-Backed

Securities

Multi-Sector

Account

Portfolio

11

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 

Debt

securities

are

generally 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.

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

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

security.

OTHER

INVESTMENT

TRANSACTIONS 

Consistent

with

its

investment

objective, the

fund

engages

in

the

following

practices

to

manage

exposure

to

certain

risks

and/or

to

enhance

performance.

The

investment

objective,

policies,

factors

of the

fund

are

described

more

fully

in the

fund’s prospectus

and

Statement

of

Additional

Information.

Mortgage-Backed

Securities

 The

fund

invests

in

mortgage-backed

securities

(MBS

or

pass-through

certificates)

that

represent

an

interest

in

a

pool

of

specific

underlying

mortgage

loans

and

entitle

the

fund

to

the

periodic

payments

of

principal

and

interest

from

those

mortgages.

MBS

may

be

issued

by

government

agencies

or

corporations,

or

private

issuers.

Most

MBS

issued

by

government

agencies

are

guaranteed;

however,

the

degree

of

protection

differs

based

on

the

issuer.

The

fund

also

invests

in

stripped

MBS,

created

when

a

traditional

MBS

is

split

into

an

interest-only

(IO)

and

a

principal-only

(PO)

strip.

MBS,

including

IOs

and

POs, are

sensitive

to

changes

in

economic

conditions

that

affect

the

rate

of

prepayments

and

defaults

on

the

underlying

mortgages;

accordingly,

the

value,

income,

and

related

cash

flows

from

MBS

may

be

more

volatile

than

other

debt

instruments.

IOs

also

risk

loss

of

invested

principal

from

faster-

than-anticipated

prepayments.

TBA

Purchase,

Sale

Commitments

and

Forward

Settling

Mortgage

Obligations

 The

fund

enters

into

to-be-

(TBA)

purchase

or

commitments

(collectively,

TBA

transactions),

pursuant

to

which

it

agrees

to

respectively,

mortgage-backed

securities

for

a

fixed

unit

price,

with

payment

and

delivery

at

a

scheduled

future

date

beyond

the

customary

settlement

period

for

such

securities.

With

TBA

transactions,

the

particular

securities

to

be

received

or

delivered

by

the

fund

are

not

identified

at

the

trade

date;

however,

the

securities

must

meet

specified

terms,

including

rate

and

mortgage

term,

and

be

within

industry-accepted

“good

standards.

The

fund

may

enter

into

TBA

transactions

with

the

intention

of

taking

possession

of

or

relinquishing

the

underlying

securities,

may

elect

to

extend

the

settlement

by

“rolling”

the

transaction,

and/or

may

use

TBA

transactions

to

gain

or

reduce

interim

TAXES

Generally,

no

provision

for

since

the

fund

intends

to continue

to

qualify

as

a

regulated

investment

company

under

Subchapter

M

of

the

Code

and

all

of

its taxable

Distributions

determined

in

with

federal

income

tax

regulations

may

differ

in

amount

or

purposes.

Financial

reporting

records

are

adjusted

for

SEGMENT

REPORTING

Operating segments

are

defined

as

components

of

a

company

that

engage

in

business

activities

and

for

which

discrete

is

available

and

regularly

reviewed

by

the

chief

maker

(CODM)

in

deciding

how

to

allocate

resources

and

assess

performance.

The

Management

Committee

of

Price Group

acts

as

the

fund’s

CODM.

The

fund

makes

investments

in

accordance

with

its

investment

objective

as

outlined

in

the

Prospectus

and

is

considered

one

reportable

segment

because

the

CODM

allocates

resources

and

assesses

the

operating

results

of

the

fund

on

the

whole.

The

fund’s

revenue

is

derived

from

investments

in

a

portfolio

of

securities.

The

CODM

allocates

resources

and

assesses

performance

based

on

the

operating

results

of

the

fund,

which

is

consistent

with

the

results

presented

in

the

statement

of

operations,

statement

of

changes

in

net

assets

and

financial

highlights.

The

CODM

compares

the

fund’s

performance

to

its

benchmark

index

and

evaluates

the

positioning

of

the

fund

in

relation

to

its

investment

objective.

The

measure

of

segment

assets

is

net

assets

of

the

fund

which

is

disclosed

in

the

statement

of

assets

and

liabilities.

The accounting

policies

of

the

segment

are

the

same

as

those

described

in

the

summary

of

significant

accounting

policies.

The

financial

statements

include

all

details

of

the

and

reflect

the

of

the

APPROVAL

OF

INVESTMENT

MANAGEMENT

AGREEMENT

Each

the

Board

of

Directors

(Board)

considers

the

continuation

of

the

investment

management

agreement

(Advisory

Contract)

between

the

fund

and

its

investment

adviser,

T.

Rowe

Price

Inc.

(Adviser).

In

that

regard,

at

a

meeting

held

on

March

11-12,

2026

(Meeting),

the

Board,

including

all

of

the

fund’s

independent

directors

who

were

present

in

person

at

the

Meeting,

approved

the

continuation

of

the

fund’s

Advisory

Contract.

At

the

Meeting,

the

Board

considered

the

factors

and

reached

the

conclusions

described

below

relating

to

the

selection

of

the

Adviser

and

the

approval

of

the

Advisory

Contract.

The

independent

directors

were

assisted

in

their

evaluation

of

the

Advisory

Contract

by

independent

legal

counsel

from

whom

they

received

separate

legal

advice

and

with

whom

they

met

separately.

In

providing

information

to

the

Board,

the

Adviser

was

guided

by

a

detailed

set

of

requests

for

information

submitted

by

independent

legal

counsel

on

behalf

of

the

independent

directors.

In

considering

and

approving

the

continuation

of

the

Advisory

Contract,

the

Board

considered

the

information

it

believed

was

relevant,

including,

but

not

limited

to,

the

information

discussed

below.

The

Board

considered

not

only

the

specific

information

presented

in

connection

with

the

Meeting

but

also

the

knowledge

gained

over

time

through

interaction

with

the

Adviser

about

various

topics

and

information

provided

to

it

by

the

Adviser.

The

Board

meets

regularly

and,

at

each

of

its

meetings,

covers

an

extensive

agenda

of

topics

and

materials

and

considers

factors

that

are

relevant

to

its

annual

consideration

of

the

renewal

of

the

T.

advisory

contracts,

including

performance

and

the

services

and

support

provided

to

the

funds

and

their

shareholders.

Services

Provided

by

the

Adviser

The

Board

considered

the

nature,

quality,

and

extent

of

the

services

provided

to

the

fund

by

the

Adviser.

These

services

include,

but

are

not

limited

to,

directing

the

fund’s

investments

in

accordance

with

its

investment

program

and

the

overall

management

of

the

fund’s

portfolio,

as

well

as

a

variety

of

related

activities

such

as

financial,

investment

operations,

and

administrative

services;

compliance

and

infrastructure,

as

well

as

compliance

with

new

and

evolving

regulatory

requirements

(e.g.,

derivatives

and

liquidity

risk

management);

maintaining

the

fund’s

records

and

registrations;

and

shareholder

communications.

The

Board

also

reviewed

the

background

and

experience

of

the

Adviser’s

senior

management

team

and

investment

personnel

involved

in

the

management

of

the

fund,

as

well

as

the

Adviser’s

compliance

record.

The

Board

concluded

that

the

information

it

considered

with

respect

to

the

nature,

quality,

and

extent

of

the

services

provided

by

the

Adviser,

as

well

as

the

other

factors

considered

at

the

Meeting,

supported

the

Board’s

of

continuation

of

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

(as

applicable)

peer

groups

of

funds

with

similar

investment

programs

for

various

periods

through

December

31,

2025.

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,

length

of

the

fund’s

performance

track

record,

and

how

closely

the

fund’s

strategies

align

with

its

benchmarks

and

peer

groups.

The

Board

noted

that,

as

of

December

31,

2025,

the

fund

lagged

its

benchmark

for

certain

performance

periods

and,

where

applicable,

the

fund’s

total

returns

ranked

in

the

4th

quartile

for

certain

periods

when

compared

to

performance

peer

groups

selected

by

third-party

data

providers.

The

Adviser

provided

the

Board

with

information

addressing

the

fund’s

performance

relative

to

its

benchmarks

and

performance

peers

(as

applicable)

during

the

applicable

periods

and

the

primary

reasons

for

such

results.

The

Board

considered

the

Adviser’s

responses

relating

to

the

fund’s

performance

during

certain

of

the

evaluated

periods

and

noted

that

it

will

continue

to

monitor

the

fund’s

performance.

The

Board

concluded

that

the

information

it

considered

with

respect

to

the

fund’s

performance,

as

well

as

the

other

factors

considered

at

the

Meeting,

supported

the

Board’s

approval

of

Costs,

Benefits,

Profits,

and

Economies

of

Scale

The

fund

does

not

pay

the

Adviser

a

management

fee

for

management

of

the

fund,

although

the

Adviser

is

compensated

indirectly

for

its

management

of

the

fund

through

investment

management

fees

it

receives

from

institutional

separately

managed

accounts

that

invest

directly

in

the

fund.

Accordingly,

the

Board

did

not

review

information

relating

to

revenues

received

by

the

Adviser

under

the

Advisory

Contract.

The

Board

did

review

information

regarding

benefits

that

the

Adviser

(and

its

affiliates)

may

have

realized

from

its

relationship

with

the

fund

or

other

T.

Rowe

Price

funds,

including

any

research

received

under

soft-dollar

arrangements

with

broker-dealers.

In

considering

soft-dollar

arrangements,

the

Board

noted

that

the

Adviser

may

use

brokerage

commissions

in

connection

with

certain

T.

Rowe

Price

funds’

securities

transactions

to

pay

for

research

when

permissible,

and

the

Board

considered

that

the

Adviser

may

receive

some

benefit

from

soft-dollar

arrangements

pursuant

to

which

research

is

received

from

broker-dealers

that

execute

the

applicable

fund’s

portfolio

transactions.

The

Board

also

received

information

on

the

estimated

costs

incurred

and

profits

realized

by

the

Adviser

and

its

affiliates

from

advising

other

T.

Rowe

Price

funds

and

concluded

that

the

Adviser’s

profits

were

reasonable.

Because

the

Adviser

does

not

receive

a

management

fee

from

the

fund,

the

Board

did

not

review

information

regarding

profits

realized

from

managing

the

fund

in

particular

or

consider

whether

the

fund

benefits

under

the

fee

levels

set

forth

in

the

Advisory

Contract

from

any

economies

of

scale

realized

by

the

Adviser.

In

addition,

the

Board

noted

that

the

fund

shares

in

potential

economies

of

scale

through

the

Adviser’s

ongoing

investments

in

its

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

management

fee

structure

for

the

fund

provides

for

a

reasonable

sharing

of

benefits

from

potential

economies

of

scale

with

the

fund

and

its

investors.

Fees

and

Expenses

The

fund

does

not

pay

an

investment

management

fee.

Under

the

Advisory

Contract,

the

Adviser

pays

all

of

the

fund’s

operating

expenses

other

than

interest

and

borrowing

expenses,

taxes,

brokerage

fees

and

commissions,

and

non-recurring

extraordinary

expenses

(subject

to

a

limit

on

the

fund’s

custody

expenses).

The

fund

bears

the

costs

associated

with

the

custody

of

the

fund’s

assets,

up

to

0.02%

of

the

fund’s

average

daily

net

assets,

and

any

custody

fees

in

excess

of

this

amount

are

borne

by

the

Adviser.

The

Board

was

provided

with

information

regarding

overall

industry

trends

in

management

fees

and

expenses

and

information

regarding

how

the

fund

compares

with

other

registered

funds

with

similar

expense

structures

that

are

also

used

as

investment

components

within

institutional

accounts.

On

the

basis

of

the

information

provided

and

the

factors

considered,

the

Board

concluded

that

the

terms

of

the

Advisory

Contract,

including

the

custody

fee

cap,

continued

to

be

appropriate.

Approval

of

the

Advisory

Contract

As

noted,

the

Board

approved

the

continuation

of

the

Advisory

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
