Dear

Shareholder,

Significant

economic

headwinds

emerged

during

the

12-month

reporting

period

ended

December

31,

2022,

as

investors

navigated

changing

economic

conditions

and

volatile

markets.

The

U.S.

economy

shrank

in

the

first

half

of

2022

before

returning

to

modest

growth

in

the

third

quarter,

marking

a

shift

to

a

more

challenging

post-reopening

economic

environment.

Changes

in

consumer

spending

patterns

and

a

tight

labor

market

led

to

elevated

inflation,

which

reached

a

40-year

high

before

beginning

to

moderate.

Moreover,

while

the

foremost

effect

of

Russia’s

invasion

of

Ukraine

has

been

a

severe

humanitarian

crisis,

the

ongoing

war

continued

to

present

challenges

for

both

investors

and

policymakers.

Equity

prices

fell

as

interest

rates

rose,

particularly

during

the

first

half

of

the

reporting

period.

Both

large-

and

small-capitalization

U.S.

stocks

fell,

although

equities

began

to

recover

in

the

second

half

of

the

year

as

inflation

eased

and

economic

growth

resumed.

Emerging

market

stocks

and

international

equities

from

developed

markets

declined

overall,

pressured

by

rising

interest

rates

and

a

strengthening

U.S.

dollar.

The

10-year

U.S.

Treasury

yield

rose

notably

during

the

reporting

period,

driving

its

price

down,

as

investors

reacted

to

fluctuating

inflation

data

and

attempted

to

anticipate

its

impact

on

future

interest

rate

changes.

The

corporate

bond

market

also

faced

inflationary

headwinds,

and

heightened

uncertainty

led

to

higher

corporate

bond

spreads

(the

difference

in

yield

between

U.S.

Treasuries

and

similarly-dated

corporate

bonds).

The

U.S.

Federal

Reserve

(the

“Fed”),

acknowledging

that

inflation

has

been

more

persistent

than

expected,

raised

interest

rates

seven

times.

Furthermore,

the

Fed

wound

down

its

bond-buying

programs

and

is

accelerating

the

reduction

of

its

balance

sheet.

While

the

Fed

suggested

that

additional

rate

hikes

were

likely,

it

also

gave

indications

that

the

pace

of

increases

would

slow

if

inflation

continued

to

subside.

The

pandemic’s

restructuring

of

the

economy

brought

an

ongoing

mismatch

between

supply

and

demand,

contributing

to

the

current

inflationary

regime.

While

growth

slowed

in

2022,

we

believe

that

taming

inflation

requires

a

more

dramatic

economic

decline

to

bring

demand

back

to

a

level

more

in

line

with

the

economy’s

capacity.

The

Fed

has

been

raising

interest

rates

at

the

fastest

pace

in

decades,

and

seems

set

to

overtighten

in

its

effort

to

get

inflation

back

to

target.

With

this

in

mind,

we

believe

the

possibility

of

a

U.S.

recession

in

the

near-term

is

high,

but

this

prospect

has

not

yet

been

fully

priced

in

by

markets.

Investors

should

expect

a

period

of

higher

volatility

as

markets

adjust

to

the

new

economic

reality

and

policymakers

attempt

to

adapt

to

rapidly

changing

conditions.

In

this

environment,

while

we

favor

an

overweight

to

equities

in

the

long-term,

the

market’s

concerns

over

excessive

rate

hikes

from

central

banks

moderate

our

outlook.

Rising

input

costs

and

a

deteriorating

economic

backdrop

are

likely

to

challenge

corporate

earnings,

so

we

are

underweight

equities

overall

in

the

near

term.

However,

we

see

better

opportunities

in

credit,

where

valuations

are

attractive

and

higher

yields

provide

income

opportunities.

We

believe

that

global

investment-grade

corporates,

global

inflation-linked

bonds,

and

U.S.

mortgage-backed

securities

offer

strong

opportunities

for

a

six-

to

twelve-month

horizon.

Overall,

our

view

is

that

investors

need

to

think

globally,

position

themselves

to

be

prepared

for

a

decarbonizing

economy,

and

be

nimble

as

market

conditions

change.

We

encourage

you

Objective

BlackRock

Inflation

Portfolio’s

(the

objective

is

to

seek

to

maximize

real

return,

consistent

with

preservation

of

real

and

Portfolio

Management

Commentary

How

did

the

Fund

perform?

For

the

12-month

period

ended

December

31,

2022,

all

of

the

Fund’s

share

classes

outperformed

the

Fund’s

benchmark,

the

Bloomberg

U.S.

Treasury

Inflation

Protected

Securities

Index,

with

the

exception

of

the

Investor

C

shares

which

underperformed.

What

factors

influenced

performance?

The

Fund

held

a

below

benchmark

stance

with

respect

to

portfolio

duration

(and

corresponding

interest

rate

sensitivity)

on

the

view

that

inflation

would

continue

to

surprise

to

the

upside

in

the

near

term

and

that

the

market

was

underestimating

the

likely

pace

of

Fed

rate

increases.

The

Fund

also

maintained

above-benchmark

exposure

to

inflation

break-evens

tactically

(the

level

of

future

inflation

required

to

compensate

for

the

lower

yield

provided

by

Treasury

Inflation

Protected

Securities

(“TIPS”)

relative

to

nominal

Treasuries).

This

positioning

benefited

performance

as

inflation

expectations

moved

higher

earlier

in

the

year

and

interest

rates

repriced

sharply

higher

over

the

year.

Tactical

underweight

positioning

in

Japanese

interest

rates

also

contributed

to

performance.

The

main

constraints

on

performance

relative

to

the

benchmark

were

the

Fund’s

exposures

to

commercial

mortgage-backed

securities

and

agency

residential

mortgage-

backed

securities

that

came

under

pressure

due

to

elevated

interest

rate

volatility

and

yield

spread

widening.

Describe

recent

portfolio

activity.

The

Fund

maintained

its

short

duration

bias

for

much

of

the

period

but

moved

to

an

above-benchmark

duration

stance

relative

to

the

benchmark

on

the

view

that

the

increased

potential

for

a

recession

may

mean

the

market

has

more

fairly

priced

in

the

likely

trajectory

of

Fed

rate

hikes.

The

Fund

utilized

derivatives

in

implementing

its

strategy,

most

notably

futures

contracts.

The

Fund’s

use

of

derivatives

contributed

marginally

to

performance.

Describe

portfolio

positioning

at

period

end.

The

Fund

was

long

U.S.

duration

as

of

the

end

of

the

reporting

period

on

the

view

that

the

market

was

pricing

in

overly

aggressive

amount

of

policy

tightening

from

the

Fed

going

forward.

The

investment

adviser

believes

inflation

has

likely

peaked

and

will

continue

to

slow

in

the

coming

months.

The

Fund

was

neutrally

positioned

with

respect

to

U.S.

inflation

despite

attractive

TIPS

valuations

on

expectations

for

a

softening

inflationary

backdrop.

Apart

from

interest

rate

and

inflation

positioning,

the

Fund

continued

to

hold

modest

exposures

to

emerging

market

debt

and

commercial

mortgage-backed

securities.

The

Benefits

of

Leveraging

/

About

Fund

Performance

The

Fund

may

utilize

leverage

to

seek

to

enhance

returns

and

net

asset

value

(“NAV”).

However,

there

is

no

guarantee

that

these

objectives

can

be

achieved

in

all

interest

rate

environments.  

The

Fund

may

utilize

leverage

by

entering

into

reverse

repurchase

agreements. 

In

general,

the

concept

of

leveraging

is

based

on

the

premise

that

the

financing

cost

of

leverage,

which

is

based

on

short-term

interest

rates,

is

normally

lower

than

the

income

earned

by

the

Fund

on

its

longer-term

portfolio

investments

purchased

with

the

proceeds

from

leverage.

To

the

extent

that

the

total

assets

of

the

Fund

(including

the

assets

obtained

from

leverage)

are

invested

in

higher-yielding

portfolio

investments,

the

Fund’s

shareholders

benefit

from

the

incremental

net

income.

The

interest

earned

on

securities

purchased

with

the

proceeds

from

leverage

is

distributed

to

the

Fund’s

shareholders,

and

the

value

of

these

portfolio

holdings

is

reflected

in

the

Fund’s

per

share

NAV.

However,

in

order

to

benefit

shareholders,

the

return

on

assets

purchased

with

leverage

proceeds

must

exceed

the

ongoing

costs

associated

with

the

leverage.

If

interest

and

other

ongoing

costs

of

leverage

exceed

the

Fund’s

return

on

assets

purchased

with

leverage

proceeds,

income

to

shareholders

is

lower

than

if

the

Fund

had

not

used

leverage.

Furthermore,

the

value

of

the

Fund’s

portfolio

investments

generally

varies

inversely

with

the

direction

of

long-term

interest

rates,

although

other

factors

can

also

influence

the

value

of

portfolio

investments.

As

a

result,

changes

in

interest

rates

can

influence

the

Fund’s

NAV

positively

or

negatively

in

addition

to

the

impact

on

the

Fund’s

performance

from

leverage.

Changes

in

the

direction

of

interest

rates

are

difficult

to

predict

accurately,

and

there

is

no

assurance

that

the

Fund’s

leveraging

strategy

will

be

successful.

The

use

of

leverage

also

generally

causes

greater

changes

in

the

Fund’s

NAV

and

dividend

rates

than

comparable

portfolios

without

leverage.

In

a

declining

market,

leverage

is

likely

to

cause

a

greater

decline

in

the

NAV

of the

Fund’s

shares

than

if

the

Fund

were

not

leveraged.

In

addition,

the

Fund

may

be

required

to

sell

portfolio

securities

at

inopportune

times

or

at

distressed

values

in

order

to

comply

with

regulatory

requirements

applicable

to

the

use

of

leverage

or

as

required

by

the

terms

of

the

leverage

instruments,

which

may

cause

the

Fund

to

incur

losses.

The

use

of

leverage

may

limit the

Fund’s

ability

to

invest

in

certain

types

of

securities

or

use

certain

types

of

hedging

strategies.

The

Fund

incurs

expenses

in

connection

with

the

use

of

leverage,

all

of

which

are

borne

by

the

Fund’s

shareholders

and

may

reduce

income.

BlackRock

Advisors,

LLC

(the

“Manager”),

the

Fund’s

investment

adviser,

has

contractually

voluntarily

agreed

to

waive

and/or

a

portion

of

the

Fund’s

expenses.

Without

such

waiver(s)

and/or

the

would

have

been

With

respect

to

the

the

Manager

is

under

no

BlackRock

Annual

Report

to

Shareholders

8

Shareholders

of

the

Fund

may

incur

the

following

charges:

(a)

transactional

expenses,

such

as

sales

charges;

and

(b)

operating

expenses,

including

investment

advisory

fees, administration

fees,

service

and

distribution

fees,

including

12b-1

fees,

acquired

fund

fees

and

expenses, and

other

fund

expenses.

The

expense

example

shown

(which

is

based

on

a

hypothetical

investment

of

$1,000

invested

at

the

beginning

of

the

period

and

held

through

the

end

of

the

period)

is

intended

to

assist

shareholders

both

in

calculating

expenses

based

on

an

investment

in

the

Fund

and

in

comparing

these

expenses

with

similar

costs

of

investing

in

other

mutual

funds.

The

expense

example

provides

information

about

actual

account

values

and

actual

expenses.

Annualized

expense

ratios

reflect

contractual

and

voluntary

fee

waivers,

if

any.

In

order

to

estimate

the

expenses

a

shareholder

paid

during

the

period

covered

by

this

report,

shareholders

can

divide

their

account

value

by

$1,000

and

then

multiply

the

result

by

the

number

corresponding

to

their share

class

under

the

heading

entitled

“Expenses

Paid

During

the

Period.” 

The

expense

example

also

provides

information

about

hypothetical

account

values

and

hypothetical

expenses

based

on the

Fund’s

actual

expense

ratio

and

an

assumed

rate

of

return

of

5%

per

year

before

expenses.

In

order

to

assist

shareholders

in

comparing

the

ongoing

expenses

of

investing

in

the

Fund

and

other

funds,

compare

the

5%

hypothetical

example

with

the

5%

hypothetical

examples

that

appear

in

shareholder

reports

of

other

funds. 

The

expenses

shown

in

the

expense

example

are

intended

to

highlight

shareholders’

ongoing

costs

only

and

do

not

reflect

transactional

expenses,

such

as

sales

charges,

if

any.

Therefore,

the

hypothetical

example is

useful

in

comparing

ongoing

expenses

only

and

will

not

help

shareholders

determine

the

relative

total

expenses

of

owning

different

funds.

If

these

transactional

expenses

were

included,

shareholder

expenses

would

have

been

higher.

Derivative

Financial

Instruments

The

Fund

may

invest

in

various

derivative

financial

instruments.

These

instruments

are

used

to

obtain

exposure

to

a

security,

commodity,

index,

market,

and/or

other

assets

without

owning

or

taking

physical

custody

of

securities,

commodities

and/or

other

referenced

assets

or

to

manage

market,

equity,

credit,

interest

rate,

foreign

currency

exchange

rate,

commodity

and/or

other

risks.

Derivative

financial

instruments

may

give

rise

to

a

form

of

economic

leverage

and

involve

risks,

including

the

imperfect

correlation

between

the

value

of

a

derivative

financial

instrument

and

the

underlying

asset,

possible

default

of

the

counterparty

to

the

transaction

or

illiquidity

of

the

instrument. Pursuant

to Rule

18f-4

under

the

1940

Act,

among

other

things,

the

Fund

must

either

use

derivative

financial

instruments

with

embedded

leverage

in

a

limited

manner

or

comply

with

an

outer

limit

on

fund

leverage

risk

based

on

value-at-risk.

The

Fund’s

successful

use

of

a

derivative

financial

instrument

depends

on

the

investment

adviser’s

ability

to

predict

pertinent

market

movements

accurately,

which

cannot

be

assured.

The

use

of

these

instruments

may

result

in

losses

greater

than

if

they

had

not

been

used,

may

limit

the

amount

of

appreciation the

Fund

can

realize

on

an

investment

and/or

may

result

in

lower

distributions

paid

to

shareholders.

The

Fund’s

investments

in

these

instruments,

if

any,

together

with

certain

other

registered

investment

companies

advised

by

BlackRock

Advisors,

LLC

(the

“Manager”) or

its

affiliates,

is

included

in

a

complex

of

funds

referred

to

as

the BlackRock

Fixed-Income

Complex.

Basis

of

Consolidation:

The

accompanying

consolidated

financial

statements

of

the

Fund

 include

the

account

of

Cayman

Inflation

Protected

Bond

Portfolio,

Ltd.

(the

“Cayman

Subsidiary”),

which

is

a

wholly-owned

subsidiary

of

the

Fund

 and

primarily

invests

in

commodity-related

instruments

and

other

derivatives

.

The

Cayman

Subsidiary

enables 

the

Fund

to

hold

these

commodity-related

instruments

and

satisfy

regulated

investment

company

tax

requirements.

The

Fund

 may

invest

up

to

25%

of

its

total

assets

in

the

Cayman

Subsidiary.

The

net

assets

of

the

Cayman

Subsidiary

as

of

period

end

were

$5,988,048

,

which

is

0.2%

 of

the

Fund’s

 consolidated

net

assets.

Intercompany

accounts

and

transactions,

if

any,

have

been

eliminated. The

Cayman

Subsidiary

is

subject

to

the

same

investment

policies

and

restrictions

that

apply

to 

the

Fund

,

except

that

the

Cayman

Subsidiary

may

invest

without

limitation

in

commodity-related

instruments. 

2.

SIGNIFICANT

ACCOUNTING

POLICIES

The

consolidated

financial

statements

are

prepared

in

conformity

with

accounting

principles

generally

accepted

in

the

United

States

of

America

(“U.S.

GAAP”),

which

may

require

management

to

make

estimates

and

assumptions

that

affect

the

reported

amounts

of

assets

and

liabilities

in

the

consolidated

financial

statements,

disclosure

of

contingent

assets

and

liabilities

at

the

date

of

the

consolidated

financial

statements

and

the

reported

amounts

of

increases

and

decreases

in

net

assets

from

operations

during

the

reporting

period.

Actual

results

could

differ

from

those

estimates.

The

Fund

is

considered

an

investment

company

under

U.S.

GAAP

and

follows

the

accounting

and

reporting

guidance

applicable

to

investment

companies.

Below

is

a

summary

of

significant

accounting

policies: 

Investment

Transactions

and

Income

Recognition:

For

financial

reporting

purposes,

investment

transactions

are

recorded

on

the

dates

the

transactions

are

executed.

Realized

gains

and

losses

on

investment

transactions

are

determined

using

the

specific

identification

method.

Dividend

income

and

capital

gain

distributions,

if

any,

are

recorded

on

the

ex-dividend

dates.

Non-cash

dividends,

if

any,

are

recorded

on

the

ex-dividend

dates

at

fair

value.

Dividends

from

foreign

securities

where

the

ex-dividend

dates

may

have

passed

are

subsequently

recorded

when

the

Fund

is

informed

of

the

ex-dividend

dates.

Under

the

applicable

foreign

tax

laws,

a

withholding

tax

at

various

rates

may

be

imposed

on

capital

gains,

dividends

and

interest.

Upon

notification

from

issuers,

a

portion

of

the

dividend

income

received

from

a

real

estate

investment

trust

may

be

redesignated

as

a

reduction

of

cost

of

the

related

investment

and/or

realized

gain.

Interest

income,

including

amortization

and

accretion

of

premiums

and

discounts

on

debt

securities,

and

payment-in-kind

interest

are

recognized

daily

on

an

accrual

basis.

Income,

expenses

and

realized

and

unrealized

gains

and

losses

are

allocated

daily

to

each

class

based

on

its

relative

net

assets. 

Foreign

Currency

Translation:

The

Fund’s

books

and

records

are

maintained

in

U.S.

dollars.

Securities

and

other

assets

and

liabilities

denominated

in

foreign

currencies

are

translated

into

U.S.

dollars

using

exchange

rates

determined

as

of

the

close

of

trading

on

the

New

York

Stock

Exchange

(“NYSE”).

Purchases

and

sales

of

investments

are

recorded

at

the

rates

of

exchange

prevailing

on

the

respective

dates

of

such

transactions.

Generally,

when

the

U.S.

dollar

rises

in

value

against

a

foreign

currency,

the

investments

denominated

in

that

currency

will

lose

value;

the

opposite

effect

occurs

if

the

U.S.

dollar

falls

in

relative

value. 

The

Fund

does

not

isolate

the

effect

of

fluctuations

in

foreign

exchange

rates

from

the

effect

of

fluctuations

in

the

market

prices

of

investments

for

financial

reporting

purposes.

Accordingly,

the

effects

of

changes

in

exchange

rates

on

investments

are

not

segregated

in

the

Consolidated

Statement

of

Operations

from

the

effects

of

changes

in

market

prices

of

those

investments,

but

are

included

as

a

component

of

net

realized

and

unrealized

gain

(loss)

from

investments.

The

Fund

reports

realized

currency

gains

(losses)

on

foreign

currency

related

transactions

as

components

of

net

realized

gain

(loss)

for

financial

reporting

purposes,

whereas

such

components

are

generally

treated

as

ordinary

income

for

U.S.

federal

income

tax

purposes.

Collateralization:

If

required

by

an

exchange

or

counterparty

agreement,

the

Fund

may

be

required

to

deliver/deposit

cash

and/or

securities

to/with

an

exchange,

or

broker-

dealer

or

custodian

as

collateral

for

certain

investments.  

Distributions:

Distributions

from

net

investment

income

are

declared

daily

and

paid

monthly.

Distributions

of

capital

gains

are

recorded

on

the

ex-dividend

dates

and

made

at

least

annually.

The

character

and

timing

of

distributions

are

determined

in

accordance

with

U.S.

federal

income

tax

regulations,

which

may

differ

from

U.S.

GAAP

.

Net

income

and

realized

gains

from

investments

held

by

the

Cayman

Subsidiary

are

treated

as

ordinary

income

for

tax

purposes. If

a

net

loss

is

realized

by

the Cayman

Subsidiary

in

any

taxable

year,

the

loss

will

generally

not

be

available

to

offset

the

Fund’s

ordinary

income

and/or

capital

gains

for

that

year.  

Deferred

Compensation

Plan:

Under

the

Deferred

Compensation

Plan

(the

“Plan”)

approved

by

the

Board

of

Trustees

of

the

Trust

(the

“Board”), the 

trustees

who

are

not

“interested

persons”

of

the

Fund,

as

defined

in

the

1940

Act

(“Independent

Trustees

”),

may

defer

a

portion

of

their

annual

complex-wide

compensation.

Deferred

amounts

earn

an

approximate

return

as

though

equivalent

dollar

amounts

had

been

invested

in

common

shares

of

certain

funds

in

the

BlackRock

Fixed-Income

Complex

selected

by

the

Independent

Trustees

.

This

has

the

same

economic

effect

for

the

Independent 

Trustees

as

if

the

Independent 

Trustees

had

invested

the

deferred

amounts

directly

in

certain

funds

in

the

BlackRock

Fixed-Income

Complex.  

The

Plan

is

not

funded

and

obligations

thereunder

represent

general

unsecured

claims

against

the

general

assets

of

the

Fund,

as

applicable.

Deferred

compensation

liabilities,

if

any, are

included

in

the Trustees

and

Officer’s

fees

payable

in

the

Consolidated

Statement

of

Assets

and

Liabilities

and

will

remain

as

a

liability

of

the

Fund

until

such

amounts

are

distributed

in

accordance

with

the

Plan.

Net

appreciation

(depreciation)

in

the

value

of

participants’

deferral

accounts

is

allocated

among

the

participating

funds

in

the

BlackRock

Fixed-Income

Complex

and

reflected

as

Trustee

and

Officer

expense

on

the

Consolidated

Statement

of

Operations.

The

Trustee

and

Officer

expense

may

be

negative

as

a

result

of

a

decrease

in

value

of

the

deferred

accounts.

Indemnifications:

In

the

normal

course

of

business,

the

Fund

enters

into

contracts

that

contain

a

variety

of

representations

that

provide

general

indemnification.

The

Fund’s

maximum

exposure

under

these

arrangements

is

unknown

because

it

involves

future

potential

claims

against

the

Fund,

which

cannot

be

predicted

with

any

certainty.

Other:

Expenses

directly

related

to the

Fund

or

its

classes

are

charged

to

the

Fund

or

the

applicable

class.

Expenses

directly

related

to

the

Fund

and

other

shared

expenses

prorated

to

the

Fund

are

allocated

daily

to

each

class

based

on

its

relative

net

assets

or

other

appropriate

methods.

Other

operating

expenses

shared

by

several

funds,

including

other

funds

managed

by

the

Manager,

are

prorated

among

those

funds

on

the

basis

of

relative

net

assets

or

other

appropriate

methods.  

3.

INVESTMENT

VALUATION

AND

FAIR

VALUE

MEASUREMENTS 

Investment

Valuation

Policies:

 The

Fund’s

investments

are

valued

at

fair

value

(also

referred

to

as

“market

value”

within

the

consolidated

financial

statements)

each

day

that

the

Fund

is

open

for

business

and,

for

financial

reporting

purposes,

as

of

the

report

date.

U.S.

GAAP

defines

fair

value

as

the

price

a

fund

would

receive

to

sell

an

asset

or

pay

to

transfer

a

liability

in

an

orderly

transaction

between

market

participants

at

the

measurement

date.

The

Board

has

approved

the

designation

of

the

Fund’s

Manager

as

the

valuation

designee

for

the

Fund.

The

Fund

determines

the

fair

values

of

its

financial

instruments

using

various

independent

dealers

or

pricing

services

under

the

Manager’s

policies.

If

a

security’s

market

price

is

not

readily

available

or

does

not

otherwise

accurately

represent

the

fair

value

of

the

security,

the

security

will

be

valued

in

accordance

with

the

Manager’s

policies

and

procedures

as

reflecting

fair

value.

The

Manager

has

formed

a

committee

(the

“Valuation

Committee”)

to

develop

pricing

policies

and

procedures

and

to

oversee

the

pricing

function

for

all

financial

instruments,

with

assistance

from

other

BlackRock

pricing

committees.

Fair

Value

Inputs

and

Methodologies:

The

following

methods

and

inputs

are

used

to

establish

the

fair

value

of

the

Fund’s

assets

and

liabilities: 

Equity

investments

traded

on

a

recognized

securities

exchange

are

valued

at

that

day’s official

closing

price,

as

applicable,

on

the

exchange

where

the

stock

is

primarily

traded.

Equity

investments

traded

on

a

recognized

exchange

for

which

there

were

no

sales

on

that

day

may

be

valued

at

the

last

available

bid

(long

positions)

or

ask

(short

positions)

price.  

Fixed-income investments

for

which

market

quotations

are

readily

available

are

generally

valued

using

the

last

available

bid

price

or

current

market

quotations

provided

by

independent

dealers

or

third-party

pricing

services.  Pricing

services

generally

value

fixed-income

securities

assuming

orderly

transactions

of

an

institutional

round

lot

size,

but

a

fund

may

hold

or

transact

in

such

securities

in

smaller,

odd

lot

sizes.

Odd

lots

may

trade

at

lower

prices

than

institutional

round

lots.

The

pricing

services

may

use

matrix

pricing

or

valuation

models

that

utilize

certain

inputs

and

assumptions

to

derive

values,

including

transaction

data

(e.g.,

recent

representative

bids

and

offers),

market

data, credit

quality

information,

perceived

market

movements,

news,

and

other

relevant

information.

Certain

fixed-income

securities,

including

asset-

backed

and

mortgage

related

securities

may

be

valued

based

on

valuation

models

that

consider

the

estimated

cash

flows

of

each

tranche

of

the

entity,

establish

a

benchmark

yield

and

develop

an

estimated

tranche

specific

spread

to

the

benchmark

yield

based

on

the

unique

attributes

of

the

tranche.

The

amortized

cost

method

of

valuation

may

be

used

with

respect

to

debt

obligations

with

sixty

days

or

less

remaining

to

maturity

unless

the

Manager

determines

such

method

does

not

represent

fair

value.

Investments

in

open-end

U.S.

mutual

funds

(including

money

market

funds) are

valued

at

that

day’s

published net

asset

value

(“NAV”).

Futures

contracts

are valued

based

on

that

day’s

last

reported

settlement

or

trade price

on

the

exchange

where

the

contract

is

traded.

Forward

foreign

currency

exchange

contracts

are

valued

at

the

mean

between

the

bid

and

ask

prices

and

are

determined

as

of

the

close

of

trading

on

the

NYSE

based

on

that

day’s

prevailing

forward

exchange

rate

for

the

underlying

currencies.

Exchange-traded

options

are

valued

at

the

mean

between

the

last bid

and

ask

prices

at

the

close

of

the

options

market in

which

the

options

trade.

An

exchange-

traded

option

for

which there

is

no

mean

price

is

valued

at

the

last

bid

(long

positions)

or

ask

(short

positions)

price.

If

no

bid

or

ask

price

is

available,

the

prior

day’s

price will

be

used,

unless

it

is

determined

that

the

prior

day’s

price

no

longer

reflects

the

fair

value

of

the

option.

Over-the-counter

(“OTC”)

options

and

options

on

swaps

(“swaptions”)

are

valued

by

an

independent

pricing

service

using

a

mathematical

model,

which

incorporates

a

number

of

market

data

factors,

such

as

the

trades

and

prices

of

the

underlying

instruments.

Swap

agreements

are

valued

utilizing

quotes

received

daily

by

independent pricing

services

or

through

brokers,

which

are

derived

using

daily

swap

curves

and

models

that

incorporate

a

number

of

market

data

factors,

such

as

discounted

cash

flows,

trades

and

values

of

the

underlying

reference

instruments. 

Notes

to

Consolidated

Financial

Statements

(continued)

35

Notes

to

Consolidated

Financial

Statements

Generally,

trading

in

foreign

instruments

is

substantially

completed

each

day

at

various

times

prior

to

the

close

of

trading

on

the

NYSE.

Each

business

day,

the

Fund

uses

current

market

factors

supplied

by

independent

pricing

services

to

value

certain

foreign

instruments

(“Systematic

Fair

Value

Price”).

The

Systematic

Fair

Value

Price

is

designed

to

value

such

foreign

securities

at

fair

value

as

of

the

close

of

trading

on

the

NYSE,

which

follows

the

close

of

the

local

markets.

If

events

(e.g.,

market

volatility,

company

announcement or

a

natural

disaster)

occur

that

are

expected

to

materially

affect

the

value

of

such

investment,

or

in

the

event

that application

of

these

methods

of

valuation

results

in

a

price

for

an

investment

that

is

deemed

not

to

be

representative

of

the

market

value

of

such

investment,

or

if

a

price

is

not

available,

the

investment

will

be

valued

by

the

Valuation

Committee

in

accordance

with the

Manager's policies

and

procedures

as

reflecting

fair

value

(“Fair

Valued

Investments”).

The

fair

valuation

approaches

that

may

be

used

by

the

Valuation

Committee include

market

approach,

income

approach

and

cost

approach.

Valuation

techniques

such

as

discounted

cash

flow,

use

of

market

comparables

and

matrix

pricing

are

types

of

valuation

approaches

and

are

typically

used

in

determining

fair

value.

When

determining

the

price

for

Fair

Valued

Investments,

the

Valuation

Committee

seeks

to

determine

the

price

that

the

Fund

might

reasonably

expect

to

receive

or

pay

from

the

current

sale

or

purchase

of

that

asset

or

liability

in

an

arm’s-length

transaction.

Fair

value

determinations

shall

be

based

upon

all

available

factors

that

the

Valuation

Committee

deems

relevant

and

consistent

with

the

principles

of

fair

value

measurement.

Fair

Value

Hierarchy:

Various

inputs

are

used

in

determining

the

fair

value

of

financial

instruments.

These

inputs

to

valuation

techniques

are

categorized

into

a

fair

value

hierarchy

consisting

of

three

broad

levels

for

financial reporting purposes

as

follows: 

Level

1

—

Unadjusted

price

quotations

in

active

markets/exchanges

for

identical

assets

or

liabilities

that

the

Fund

has

the

ability

to

access;

Level

2

—

Other

observable

inputs

(including,

but

not

limited

to,

quoted

prices

for

similar

assets

or

liabilities

in

markets

that

are

active,

quoted

prices

for

identical

or

similar

assets

or

liabilities

in

markets

that

are

not

active,

inputs

other

than

quoted

prices

that

are

observable

for

the

assets

or

liabilities

(such

as

interest

rates,

yield

curves,

volatilities,

prepayment

speeds,

loss

severities,

credit

risks

and

default

rates)

or

other

market–corroborated

inputs);

and 

Level

3 —

Unobservable

inputs

based

on

the

best

information

available

in

the

circumstances,

to

the

extent

observable

inputs

are

not

available

(including

the

Valuation

Committee’s

assumptions

used

in

determining

the

fair

value

of

financial

instruments).

The

hierarchy

gives

the

highest

priority

to

unadjusted

quoted

prices

in

active

markets

for

identical

assets

or

liabilities

(Level

1

measurements)

and

the

lowest

priority

to

unobservable

inputs

(Level

3

measurements).

Accordingly,

the

degree

of

judgment

exercised

in

determining

fair

value

is

greatest

for

instruments

categorized

in

Level

3.

The

inputs

used

to

measure

fair

value

may

fall

into

different

levels

of

the

fair

value

hierarchy.

In

such

cases,

for

disclosure

purposes,

the

fair

value

hierarchy

classification

is

determined

based

on

the

lowest

level

input

that

is

significant

to

the

fair

value

measurement

in

its

entirety. Investments

classified

within

Level

3

have

significant

unobservable

inputs

used

by

the

Valuation

Committee

in

determining

the

price

for

Fair

Valued

Investments.

Level

3

investments

include

equity

or

debt

issued

by

privately

held

companies

or

funds

that

may

not

have

a

secondary

market

and/or

may

have

a

limited

number

of

investors.

The

categorization

of

a

value

determined

for

financial

instruments

is

based

on

the

pricing

transparency

of

the financial

instruments

and

is

SECURITIES

AND

OTHER

INVESTMENTS 

Asset-Backed

and

Mortgage-Backed

Securities:

Asset-backed

securities

are

generally

issued

as

pass-through

certificates

or

as

debt

instruments.

Asset-backed

securities

issued

as

pass-through

certificates

represent

undivided

fractional

ownership

interests

in

an

underlying

pool

of

assets.

Asset-backed

securities

issued

as

debt

instruments,

which

are

also

known

as

collateralized

obligations,

are

typically

issued

as

the

debt

of

a

special

purpose

entity

organized

solely

for

the

purpose

of

owning

such

assets

and

issuing

such

debt.

Asset-backed

securities

are

often

backed

by

a

pool

of

assets

representing

the

obligations

of

a

number

of

different

parties.

The

yield

characteristics

of

certain

asset-backed

securities

may

differ

from

traditional

debt

securities.

One

such

major

difference

is

that

all

or

a

principal

part

of

the

obligations

may

be

prepaid

at

any

time

because

the

underlying

assets

(i.e.,

loans)

may

be

prepaid

at

any

time.

As

a

result,

a

decrease

in

interest

rates

in

the

market

may

result

in

increases

in

the

level

of

prepayments

as

borrowers,

particularly

mortgagors,

refinance

and

repay

their

loans.

An

increased

prepayment

rate

with

respect

to

an

asset-backed

security

will

have

the

effect

of

shortening

the

maturity

of

the

security.

In

addition,

a

fund

may

subsequently

have

to

reinvest

the

proceeds

at

lower

interest

rates.

If

a

fund

has

purchased

such

an

asset-backed

security

at

a

premium,

a

faster

than

anticipated

prepayment

rate

could

result

in

a

loss

of

principal

to

the

extent

of

the

premium

paid. 

For

mortgage

pass-through

securities

(the

“Mortgage

Assets”)

there

are

a

number

of

important

differences

among

the

agencies

and

instrumentalities

of

the

U.S.

Government

that

issue

mortgage-related

securities

and

among

the

securities

that

they

issue.

For

example,

mortgage-related

securities

guaranteed

by

Ginnie

Mae

are

guaranteed

as

to

the

timely

payment

of

principal

and

interest

by

Ginnie

Mae

and

such

guarantee

is

backed

by

the

full

faith

and

credit

of

the

United

States.

However,

mortgage-related

securities

issued

by

Freddie

Mac

and

Fannie

Mae,

including

Freddie

Mac

and

Fannie

Mae

guaranteed

mortgage

pass-through

certificates,

which

are

solely

the

obligations

of

Freddie

Mac

and

Fannie

Mae,

are

not

backed

by

or

entitled

to

the

full

faith

and

credit

of

the

United

States,

but

are

supported

by

the

right

of

the

issuer

to

borrow

from

the

U.S.

Treasury. 

Non-agency

mortgage-backed

securities

are

securities

issued

by

non-governmental

issuers

and

have

no

direct

or

indirect

government

guarantees

of

payment

and

are

subject

to

various

risks.

Non-agency

mortgage

loans

are

obligations

of

the

borrowers

thereunder

only

and

are

not

typically

insured

or

guaranteed

by

any

other

person

or

entity.

The

ability

of

a

borrower

to

repay

a

loan

is

dependent

upon

the

income

or

assets

of

the

borrower.

A

number

of

factors,

including

a

general

economic

downturn,

acts

of

God,

terrorism,

social

unrest

and

civil

disturbances,

may

impair

a

borrower’s

ability

to

repay

its

loans.

Inflation-Indexed

Bonds:

Inflation-indexed

bonds

(other

than

municipal

inflation-indexed

and

certain

corporate

inflation-indexed

bonds)

are

fixed-income

securities

whose

principal

value

is

periodically

adjusted

according

to

the

rate

of

inflation.

If

the

index

measuring

inflation

rises

or

falls,

the

principal

value

of

inflation-indexed

bonds

(other

than

municipal

inflation-indexed

and

certain

corporate

inflation-indexed

bonds)

will

be

adjusted

upward

or

downward,

and

consequently

the

interest

payable

on

these

securities

(calculated

with

respect

to

a

larger

or

smaller

principal

amount)

will

be

increased

or

reduced,

respectively.

Any

upward

or

downward

adjustment

in

the

principal

amount

of

an

inflation-indexed

bond

is

included

as

interest

income

in

the

Consolidated

Statement

of

Operations,

even

though

investors

do

not

receive

their

principal

until

maturity.

Repayment

of

the

original

bond

principal

upon

maturity

(as

adjusted

for

inflation)

is

guaranteed

in

the

case

of

U.S.

Treasury

inflation-indexed

bonds.

For

bonds

that

do

not

provide

a

similar

guarantee,

the

adjusted

principal

value

of

the

bond

repaid

at

maturity

may

be

less

than

the

original

principal.

With

regard

to

municipal

inflation-indexed

bonds

and

certain

corporate

inflation-indexed

bonds,

the

inflation

adjustment

is

typically

reflected

in

the

semi-annual

coupon

payment.

As

a

result,

the

principal

value

of

municipal

inflation-indexed

bonds

and

such

corporate

inflation-indexed

bonds

does

not

adjust

according

to

the

rate

of

inflation.

Multiple

Class

Pass-Through

Securities:

Multiple

class

pass-through

securities,

including

collateralized

mortgage

obligations

(“CMOs”)

and

commercial

mortgage-backed

securities,

may

be

issued

by

Ginnie

Mae,

U.S.

Government

agencies

or

instrumentalities

or

by

trusts

formed

by

private

originators

of,

or

investors

in,

mortgage

loans.

In

general,

CMOs

are

debt

obligations

of

a

legal

entity

that

are

collateralized

by

a

pool

of

residential

or

commercial

mortgage

loans

or

Mortgage

Assets.

The

payments

on

these

are

used

to

make

payments

on

the

CMOs

or

multiple

pass-through

securities.

Multiple

class

pass-through

securities

represent

direct

ownership

interests

in

the

Mortgage

Assets.

Classes

of

CMOs

include

interest

only

(“IOs”),

principal

only

(“POs”),

planned

amortization

classes

and

targeted

amortization

classes.

IOs

and

POs

are

stripped

mortgage-backed

securities

representing

interests

in

a

pool

of

mortgages,

the

cash

flow

from

which

has

been

separated

into

interest

and

principal

components.

IOs

receive

the

interest

portion

of

the

cash

flow

while

POs

receive

the

principal

portion.

IOs

and

POs

can

be

extremely

volatile

in

response

to

changes

in

interest

rates.

As

interest

rates

rise

and

fall,

the

value

of

IOs

tends

to

move

in

the

same

direction

as

interest

rates.

POs

perform

best

when

prepayments

on

the

underlying

mortgages

rise

since

this

increases

the

rate

at

which

the

principal

is

returned

and

the

yield

to

maturity

on

the

PO.

When

payments

on

mortgages

underlying

a

PO

are

slower

than

anticipated,

the

life

of

the

PO

is

lengthened

and

the

yield

to

maturity

is

reduced.

If

the

underlying

Mortgage

Assets

experience

greater

than

anticipated

prepayments

of

principal,

a

fund’s

initial

investment

in

the

IOs

may

not

fully

recoup. 

TBA

Commitments:

TBA

commitments

are

forward

agreements

for

the

purchase

or

sale

of

securities,

including

mortgage-backed

securities

for

a

fixed

price,

with

payment

and

delivery

on

an

agreed

upon

future

settlement

date.

The

specific

securities

to

be

delivered

are

not

identified

at

the

trade

date.

However,

delivered

securities

must

meet

specified

terms,

including

issuer,

rate

and

mortgage

terms.

When

entering

into

TBA

commitments,

a

fund

may

take

possession

of

or

deliver

the

underlying

mortgage-backed

securities

but

can

extend

the

settlement

or

roll

the

transaction.

TBA

commitments

involve

a

risk

of

loss

if

the

value

of

the

security

to

be

purchased

or

sold

declines

or

increases,

respectively,

prior

to

settlement

date,

if

there

are

expenses

or

delays

in

connection

with

the

TBA

transactions,

or

if

the

counterparty

fails

to

complete

the

transaction.

In

order

to

better

define

contractual

rights

and

to

secure

rights

that

will

help

a

fund

mitigate its

counterparty

risk,

TBA

commitments

may

be

entered

into

by

a

fund

under

Master

Securities

Forward

Transaction

Agreements

(each,

an

“MSFTA”).

An

MSFTA

typically

contains,

among

other

things,

collateral

posting

terms

and

netting

provisions

in

the

event

of

default

and/or

termination

event. The

collateral

requirements

are

typically

calculated

by

netting

the

mark-to-market

amount

for

each

transaction

under

such

agreement

and

comparing

that

amount

to

the

value

of

the

collateral

currently

pledged

by

a

fund

and

the

counterparty. Cash

collateral

that

has

been

pledged

to

cover

the

obligations

of

a

fund

and

cash

collateral

received

from

the

counterparty,

if

any,

is

reported

separately

in

the

Consolidated

Statement

of

Assets

and

Liabilities

as

cash

pledged

as

collateral

for

TBA

commitments

or

cash

received

as

collateral

for

TBA

commitments,

respectively.

Non-cash

collateral

pledged

by

a

fund,

if

any,

is

noted

in

the

Consolidated

Schedule

of

Investments. Typically,

a

fund

is

permitted

to

sell,

re-pledge

or

use

the

collateral

it

receives;

however,

the

counterparty

is

not

permitted

to

do

so.

To

the

extent

amounts

due

to

a

fund

are

not

fully

collateralized,

contractually

or

otherwise,

a

fund

bears

the

risk

of

loss

from

counterparty

non-performance.

Mortgage

Dollar

Roll

Transactions

:

The

Fund

may

sell

TBA

mortgage-backed

securities

and

simultaneously

contract

to

repurchase

substantially

similar

(i.e.,

same

type,

coupon

and

maturity)

securities

on

a

specific

future

date

at

an

agreed

upon

price.

During

the

period

between

the

sale

and

repurchase,

a

fund

is

not

entitled

to

receive

interest

and

principal

payments

on

the

securities

sold.

Mortgage

dollar

roll

transactions

are

treated

as

purchases

and

sales

and

a

fund realizes

gains

and

losses

on

these

transactions.

Mortgage

dollar

rolls

involve

the

risk

that

the

market

value

of

the

securities

that

a

fund

is

required

to

purchase

may

decline

below

the

agreed

upon

repurchase

price

of

those

securities.

Borrowed

Bond

Agreements:

Repurchase

agreements

may

be

referred

to

as

borrowed

bond

agreements

when

entered

into

in

connection

with

short

sales

of

bonds.

In

a

borrowed

bond

agreement,

a

fund

borrows

a

bond

from

a

counterparty

in

exchange

for

cash

collateral.

The

agreement

contains

a

commitment

that

the

security

and

the

cash

will

be

returned

to

the

counterparty

and

a

fund

at

a

mutually

agreed

upon

date.

Certain

agreements

have

no

stated

maturity

and

can

be

terminated

by

either

party

at

any

time.

Earnings

on

cash

collateral

and

compensation

to

the

lender

of

the

bond

are

based

on

agreed

upon

rates

between

a

fund

and

the

counterparty.

The

value

of

the

underlying

cash

collateral

approximates

the

market

value

and

accrued

interest

of

the

borrowed

bond.

To

the

extent

that

a

borrowed

bond

transaction

exceeds

one

business

day,

the

value

of

the

cash

collateral

in

the

possession

of

the

counterparty

is

monitored

on

a

daily

basis

to

ensure

the

adequacy

of

the

collateral.

As

the

market

value

of

the

borrowed

bond

changes,

the

cash

collateral

is

periodically

increased

or

decreased

with

a

frequency

and

in

amounts

prescribed

in

the

borrowed

bond

agreement.

A

fund

may

also

experience

delays

in

gaining

access

to

the

collateral.

Reverse

Repurchase

Agreements:

Reverse

repurchase

agreements

are

agreements

with

qualified

third-party

broker

dealers

in

which

a

fund

sells

securities

to

a

bank

or

broker-dealer

and

agrees

to

repurchase

the

same

securities

at

a

mutually

agreed

upon

date

and

price.

A

fund

receives

cash

from

the

sale

to

use

for

other

investment

purposes.

During

the

term

of

the

reverse

repurchase

agreement,

a

fund

continues

to

receive

the

principal

and

interest

payments

on

the

securities

sold.

Certain

agreements

have

no

stated

maturity

and

can

be

terminated

by

either

party

at

any

time.

Interest

on

the

value

of

the

reverse

repurchase

agreements

issued

and

outstanding

is

based

upon

competitive

market

rates

determined

at

the

time

of

issuance.

A

fund

may

utilize

reverse

repurchase

agreements

when

it

is

anticipated

that

the

interest

income

to

be

earned

from

the

investment

of

the

proceeds

of

the

transaction

is

greater

than

the

interest

expense

of

the

transaction.

Reverse

repurchase

agreements

involve

leverage

risk.

If

a

fund

suffers

a

loss

on

its

investment

of

the

transaction

proceeds

from

a

reverse

repurchase

agreement,

a

fund

would

still

be

required

to

pay

the

full

repurchase

price.

Further,

a

fund

remains

subject

to

the

risk

that

the

market

value

of

the

securities

repurchased

declines

below

the

repurchase

price.

In

such

cases,

a

fund

would

be

required

to

return

a

portion

of

the

cash

received

from

the

transaction

or

provide

additional

securities

to

the

counterparty. 

Cash

received

in

exchange

for

securities

delivered

plus

accrued

interest

due

to

the

counterparty

is

recorded

as

a

liability

in

the

Consolidated

Statement

of

Assets

and

Liabilities

at

face

value

including

accrued

interest.

Due

to

the

short-term

nature

of

the

reverse

repurchase

agreements,

face

value

approximates

fair

value.

Interest

payments

made

by

a

fund

to

the

counterparties

are

recorded

as

a

component

of

interest

expense

in

the

Consolidated

Statement

of

Operations.

In

periods

of

increased

demand

for

the

security,

a

fund

may

receive

a

fee

for

the

use

of

the

security

by

the

counterparty,

which

may

result

in

interest

income

to

a

fund.

For

the

year

ended

December

31,

2022,

the

average

daily

amount

of

reverse

repurchase

agreements

outstanding and

the

weighted

average

interest

rate

for

the

Fund

were

$449,892,871

and

1.74%,

respectively.

Borrowed

bond

agreements

and

reverse

repurchase

transactions are

entered

into

by

a

fund

under

Master

Repurchase

Agreements

(each,

an

“MRA”),

which

permit

a

fund,

under

certain

circumstances,

including

an

event

of

(such

as

bankruptcy

or

insolvency),

to

offset

payables

and/or

receivables

under

the

MRA

with

collateral

held

and/

or

posted

to

the

counterparty

and

create

one

single

net

payment

due

to

or

from

a

fund.

With

borrowed

bond

agreements

and

reverse

repurchase

transactions,

typically

a

fund

and

counterparty

under

an

MRA

are

permitted

to

sell,

re-pledge,

or

the

associated

with

Bankruptcy

the

with

value

in

excess

of

the

repurchase

price

to

be

paid

or

by

a

fund

upon

maturity

of

the

Upon

a

of

a

fund

is

considered

an

unsecured

creditor

with

respect

to

excess

collateral

and,

as

such,

the

return

of

excess

collateral

may

be

delayed.

As

of

period

end,

the

following

table

is

a

summary

of

the

Fund’s

open

borrowed

bond

agreements

and

reverse

repurchase

agreements by

counterparty

which

are

subject

to

offset

under

an

MRA

on

a

net

basis:

In

the

event

the

counterparty

of

securities

under

an

MRA

files

for

bankruptcy

or

becomes

insolvent,

a

fund’s

use

of

the

proceeds

from

the

agreement

may

be

restricted

while

the

counterparty,

or

its

trustee

or

receiver,

determines

whether

or

not

to

enforce

a

fund’s

obligation

to

repurchase

the

securities.

Short

Sale

Transactions:

 In

short

sale

transactions,

a

fund

sells

a

security

it

does

not

hold

in

anticipation

of

a

decline

in

the

market

price

of

that

security.

When

a

fund

makes

a

short

sale,

it

will

borrow

the

security

sold

short

(borrowed

bond)

and

deliver

the

fixed-income

security

to

the

counterparty

to

which

it

sold

the

security

short.

An

amount

equal

to

the

proceeds

received

by

a

fund

is

reflected

as

an

asset

and

an

equivalent

liability.

The

amount

of

the

liability

is

subsequently

marked-to-market

to

reflect

the

market

value

of

the

short

sale.

A

fund

is

required

to

repay

the

counterparty

interest

on

the

security

sold

short,

which,

if

applicable,

is

included

in

interest

expense

in

the

Consolidated

Statement

of

Operations.

A

fund

is

exposed

to

market

risk

based

on

the

amount,

if

any,

that

the

market

value

of

the

security

increases

beyond

the

market

value

at

which

the

position

was

sold.

Thus,

a

short

sale

of

a

security

involves

the

risk

that

instead

of

declining,

the

price

of

the

security

sold

short

will

rise.

The

short

sale

of

securities

involves

the

possibility

of

an

unlimited

loss

since

there

is

an

unlimited

potential

for

the

market

price

of

the

security

sold

short

to

increase.

A

gain

is

limited

to

the

price

at

which

a

fund

sold

the

security

short.

A

realized

gain

or

loss

is

recognized

upon

the

termination

of

a

short

sale

if

the

market

price

is

either

less

than

or

greater

than

the

proceeds

originally

received.

There

is

no

assurance

that

a

fund

will

be

able

to

close

out

a

short

position

at

a

particular

time

or

at

an

acceptable

price.

in

various

portfolio

investment

strategies

using

derivative

contracts

both

to

increase

the

returns

of

the

to

manage

its

exposure

to

certain

risks

such

as

credit

risk,

equity

risk,

interest

risk,

foreign

currency

exchange

rate

risk,

commodity

or

other

risks

(e.g.,

Derivative

financial

instruments

categorized

by

risk

exposure

are

included

in

the

Consolidated

Schedule

of

Investments.

These

contracts

may

be

transacted

on

an

exchange or

OTC.

Futures

Contracts:

Futures

contracts

are

purchased

or

sold

to

gain

exposure

to,

or

manage

exposure

to,

changes

in

interest

rates

(interest

rate

risk)

and

changes

in

the

value

of

equity

securities

(equity

risk)

or

foreign

currencies

(foreign

currency

exchange

rate

risk)

.

Futures

contracts

are

exchange-traded agreements

between

the

Fund

and

a

counterparty

to

buy

or

sell

a

specific

quantity

of

an

underlying

instrument

at

a

specified

price

and

on

a

specified

date.

Depending

on

the

terms

of

a

contract,

it

is

settled

either

through

physical

delivery

of

the

underlying

instrument

on

the

settlement

date

or

by

payment

of

a

cash

amount

on

the

settlement

date.

Upon

entering

into

a

futures

contract,

the

Fund

is

required

to

deposit

initial

margin

with

the

broker

in

the

form

of

cash

or

securities

in

an

amount

that

varies

depending

on

a

contract’s

size

and

risk

profile.

The

initial

margin

deposit

must

then

be

maintained

at

an

established

level

over

the

life

of

the

contract.

Amounts

pledged,

which

are

considered

restricted,

are

included

in

cash

pledged

for

futures

contracts

in

the Consolidated

Statement

of

Assets

and

Liabilities.

Securities

deposited

as

initial

margin

are

designated

in

the

Consolidated

Schedule

of

Investments

and

cash

deposited,

if

any, are

shown

as

cash

pledged

for

futures

contracts

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

Pursuant

to

the

contract,

the

Fund

agrees

to

receive

from

or

pay

to

the

broker

an

amount

of

cash

equal

to

the

daily

fluctuation

in

market

value

of

the

contract

(“variation

margin”).

Variation

margin

is

recorded

as

unrealized

appreciation

(depreciation)

and,

if

any,

shown

as

variation

margin

receivable

(or

payable)

on

futures

contracts

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

When

the

contract

is

closed,

a

realized

gain

or

loss

is

recorded

in

the

Consolidated

Statement

of

Operations

equal

to

the

difference

between

the

notional

amount

of

the

contract

at

the

time

it

was

opened

and

the

notional

amount

at

the

time

it

was

closed.

The

use

of

futures

contracts

involves

the

risk

of

an

imperfect

correlation

in

the

movements

in

the

price

of

futures

contracts

and

interest

rates,

foreign

currency

exchange

rates

or

Forward

Foreign

Currency

Exchange

Contracts

:

Forward

foreign

currency

exchange

contracts

are

entered

into

to

gain

or

reduce

exposure

to

foreign

currencies

(foreign

currency

exchange

rate

risk).

A

forward

foreign

currency

exchange

contract

is

an

agreement

between

two

parties

to

buy

and

sell

a

currency

at

a

set

exchange

rate

on

a

specified

date.

These

contracts

help

to

manage

the

overall

exposure

to

the

currencies

in

which

some

of

the

investments

held

by

the

Fund

are

denominated

and

in

some

cases,

may

be

used

to

obtain

exposure

to

a

particular

market.

The

contracts

are

traded

OTC

and

not

on

an

organized

exchange.

The

contract

is

marked-to-market

daily

and

the

change

in

market

value

is

recorded

as

unrealized

appreciation

(depreciation)

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

When

a

contract

is

closed,

a

realized

gain

or

loss

is

recorded

in

the

Consolidated

Statement

of

Operations

equal

to

the

difference

between

the

value

at

the

time

it

was

opened

and

the

value

at

the

time

it

was

closed.

Non-deliverable

forward

foreign

currency

exchange

contracts

are

settled

with

the

counterparty

in

cash

without

the

delivery

of

foreign

currency.

The

use

of

forward

foreign

currency

exchange

contracts

involves

the

risk

that

the

value

of

a

forward

foreign

currency

exchange

contract

changes

unfavorably

due

to

movements

in

the

value

of

the

referenced

foreign

currencies,

and

such

value

may

exceed

the

amount(s)

reflected

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

Cash

amounts

pledged

for

forward

foreign

currency

exchange

contracts

are

considered

restricted

and

are

included

in

cash

pledged

as

collateral

for

OTC

derivatives

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

A

Fund’s

risk

of

loss

from

counterparty

credit

risk

on

OTC

derivatives

is

generally

limited

to

the

aggregate

unrealized

gain

netted

against

any

collateral

held

by

the

Fund.

Options:

The

Fund

may purchase

and

write

call

and

put

options

to

increase

or

decrease

its

exposure

to

the

risks

of

underlying

instruments,

including

equity

risk,

interest

rate

risk

and/or

commodity

price

risk

and/or,

in

the

case

of

options

written,

to

generate

gains

from

options

premiums.

A

call

option

gives

the

purchaser

(holder)

of

the

option

the

right

(but

not

the

obligation)

to

buy,

and

obligates

the

seller

(writer)

to

sell

(when

the

option

is

exercised)

the

underlying

instrument

at

the

exercise

or

strike

price

at

any

time

or

at

a

specified

time

during

the

option

period.

A

put

option

gives

the

holder

the

right

to

sell

and

obligates

the

writer

to

buy

the

underlying

instrument

at

the

exercise

or

strike

price

at

any

time

or

at

a

specified

time

during

the

option

period.

Premiums

paid

on

options

purchased

and

premiums

received

on

options

written,

as

well

as

the

daily

fluctuation

in

market

value,

are

included

in

investments

at

value

–

unaffiliated

and

options

written

at

value,

respectively,

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

When

an

instrument

is

purchased

or

sold

through

the

exercise

of

an

option,

the

premium

is

offset

against

the

cost

or

proceeds

of

the

underlying

instrument.

When

an

option

expires,

a

realized

gain

or

loss

is

recorded

in

the

Consolidated

Statement

of

Operations

to

the

extent

of

the

premiums

received

or

paid.

When

an

option

is

closed

or

sold,

a

gain

or

loss

is

recorded

in

the

Consolidated

Statement

of

Operations

to

the

extent

the

cost

of

the

closing

transaction

exceeds

the

premiums

received

or

paid.

When

the

Fund

writes

a

call

option,

such

option

is

typically

“covered,”

meaning

that

it

holds

the

underlying

instrument

subject

to

being

called

by

the

option

counterparty.

When

the

Fund

writes

a

put

option,

cash

is

segregated in

an

amount

sufficient

to

cover

the

obligation.

These

amounts,

which

are

considered

restricted,

are

included

in

cash

pledged

as

collateral

for

options

written

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

Swaptions

–

The

Fund

may purchase

and

write

swaptions

primarily

to

preserve

a

return

or

spread

on

a

particular

investment

or

portion

of

the

Fund’s

holdings,

as

a

duration

management

technique

or

to

protect

against

an

increase

in

the

price

of

securities

it

anticipates

purchasing

at

a

later

date.

The

purchaser

and

writer

of

a

swaption

is

buying

or

granting

the

right

to

enter

into

a

previously

agreed

upon

interest

rate

or

credit

default

swap

agreement

(interest

rate

risk

and/or

credit

risk)

at

any

time

before

the

expiration

of

the

option. 

Foreign

currency

options

–

The

Fund

may purchase

and

write

foreign

currency

options,

foreign

currency

futures

and

options

on

foreign

currency

futures

to

gain

or

reduce

exposure

to

foreign

currencies

(foreign

currency

exchange

rate

risk).

Foreign

currency

options

give

the

purchaser

the

right

to

buy

from

or

sell

to

the

writer

a

foreign

currency

at

any

time

before

the

expiration

of

the

option.

In

purchasing

and

writing

options,

the

Fund

bears

the

risk

of

an

unfavorable

change

in

the

value

of

the

underlying

instrument

or

the

risk

that

it

may

not

be

able

to

enter

into

a

closing

transaction

due

to

an

illiquid

market.

Exercise

of

a

written

option

could

result

in

the

Fund

purchasing

or

selling

a

security

when

it

otherwise

would

not,

or

at

a

price

different

from

the

current

market

value.

Swaps:

Swap

contracts

are

entered

into

to

manage

exposure

to

issuers,

markets

and

securities.

Such

contracts

are

agreements

between

the

Fund

and

a

counterparty

to

make

periodic

net

payments

on

a

specified

notional

amount

or

a

net

payment

upon

termination.

Swap

agreements

are

privately

negotiated

in

the

OTC

market

and

may

be

entered

into

as

a

bilateral

contract

(“OTC

swaps”)

or

centrally

cleared

(“centrally

cleared

swaps”).

For

OTC

swaps,

any

upfront

premiums

paid

and

any

upfront

fees

received

are

shown

as

swap

premiums

paid

and

swap

premiums

received,

respectively,

in

the

Consolidated

Statement

of

Assets

and

Liabilities

and

amortized

over

the

term

of

the

contract.

The

daily

fluctuation

in

market

value

is

recorded

as

unrealized

appreciation

(depreciation)

on

OTC

Swaps

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

Payments

received

or

paid

are

recorded

in

the

Consolidated

Statement

of

Operations

as

realized

gains

or

losses,

respectively.

When

an

OTC

swap

is

terminated,

a

realized

gain

or

loss

is

recorded

in

the

Consolidated

Statement

of

Operations

equal

to

the

difference

between

the

proceeds

from

(or

cost

of)

the

closing

transaction

and

the

Fund’s

basis

in

the

contract,

if

any.

Generally,

the

basis

of

the

contract

is

the

premium

received

or

paid.

In

a

centrally

cleared

swap,

immediately

following

execution

of

the

swap

contract,

the

swap

contract

is

novated

to

a

central

counterparty

(the

“CCP”)

and

the

CCP

becomes

the Fund’s

counterparty

on

the

swap.

The

Fund

is

required

to

interface

with

the

CCP

through

the

broker.

Upon

entering

into

a

centrally

cleared

swap,

the

Fund

is

required

to

deposit

initial

margin

with

the

broker

in

the

form

of

cash

or

securities

in

an

amount

that

varies

depending

on

the

size

and

risk

profile

of

the

particular

swap. Securities

deposited

as

initial

margin

are

designated

in

the

Consolidated

Schedule

of

Investments

and

cash

deposited

is

shown

as

cash

pledged

for

centrally

cleared

swaps

in

the

Consolidated

Statement

of

Assets

and

Liabilities. Amounts

pledged,

which

are

considered

restricted

cash,

are

included

in

cash

pledged

for

centrally

cleared

swaps

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

Pursuant

to

the

contract,

the

Fund

agrees

to

receive

from

or

pay

to

the

broker

variation

margin.

Variation

margin

is

recorded

as

unrealized

appreciation

(depreciation)

and

shown

as

variation

margin

receivable

(or

payable)

on

centrally

cleared

swaps

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

Payments

received

from

(paid

to)

the

counterparty

are

amortized

over

the

term

of

the

contract

and

recorded

as

realized

gains

Interest

rate

swaps

—

Interest

rate

swaps

are

entered

into

to

gain

or

reduce

exposure

to

interest

rates

or

to

manage

duration,

the

yield

curve

or

interest

rate

(interest

rate

risk).

Interest

rate

swaps

are

agreements

in

which

one

party

pays

a

stream

of

interest

payments,

either

fixed

or

floating,

in

exchange

for

another

party’s

stream

of

interest

payments,

either

fixed

or

floating,

on

the

same

notional

amount

for

a

specified

period

of

time.

In

more

complex

interest

rate

swaps,

the

notional

principal

amount

may

decline

(or

amortize)

over

time.

Forward

swaps

—

The

Fund

may enter

into

forward

interest

rate

swaps

and

forward

total

return

swaps.

In

a

forward

swap,

the

Fund

and

the

counterparty

agree

to

make

periodic

net

payments

beginning

on

a

specified

date

or

a

net

payment

at

termination.

Inflation

swaps

—

Inflation

swaps

are

entered

into

to

gain

or

reduce

exposure

to

inflation

(inflation

risk).

In

an

inflation

swap,

one

party

makes

fixed

interest

payments

on

a

notional

principal

amount

in

exchange

for

another

party’s

variable

payments

based

on

an

inflation

index,

such

as

the

Consumer

Price

Index.

Swap

transactions

involve,

to

varying

degrees,

elements

of

interest

rate,

credit

and

market

risks

in

excess

of

the

amounts

recognized

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

Such

risks

involve

the

possibility

that

there

will

be

no

liquid

market

for

these

agreements,

that

the

counterparty

to

the

agreements

may

default

on

its

obligation

to

perform

or

disagree

as

to

the

meaning

of

the

rights

and

to

secure

rights

that

will

help

it mitigate its

counterparty

risk, the

Fund

may

enter

into

an

International

Swaps

and

Derivatives

Association,

Inc.

Master

Agreement

(“ISDA

Master

Agreement”)

or

similar

agreement

with

its

counterparties.

An

ISDA

Master

Agreement

is

a

bilateral

agreement

between a

Fund

and

a

counterparty

that

governs

certain

OTC

derivatives

and

typically

contains,

among

other

things,

collateral

posting

terms

and

netting

provisions

in

the

event

of

a

default

and/or

termination

event.

Under

an

ISDA

Master

Agreement, a

Fund

may,

under

certain

circumstances,

offset

with

the

counterparty

certain

derivative

financial

instruments’

payables

and/or

receivables

with

collateral

held

and/or

posted

and

create

one

single

net

payment.

The

provisions

of

the

ISDA

Master

Agreement

typically

permit

a

single

net

payment

in

the

event

of

default

including

the

bankruptcy

or

insolvency

of

the

counterparty.

However,

bankruptcy

or

insolvency

laws

of

a

particular

jurisdiction

may

impose

restrictions

on

or

prohibitions

against

the

right

of

offset

in

bankruptcy,

insolvency

or

other

events.

Collateral

Requirements:

For

derivatives

traded

under

an

ISDA

Master

Agreement,

the

collateral

requirements

are

typically

calculated

by

netting

the

mark-to-market

amount

for

each

transaction

under

such

agreement

and

comparing

that

amount

to

the

value

of

any

collateral

currently

pledged

by

the

Fund

and

the

counterparty.

Cash

collateral

that

has

been

pledged

to

cover

obligations

of

the

Fund

and

cash

collateral

received

from

the

counterparty,

if

any,

is

reported

separately

in

the

Consolidated

Statement

of

Assets

and

Liabilities

as

cash

pledged

as

collateral

and

cash

received

as

collateral,

respectively.

Non-cash

collateral

pledged

by

the

Fund,

if

any,

is

noted

in

the

Consolidated

Schedule

of

Investments.

Generally,

the

amount

of

collateral

due

from

or

to

a

counterparty

is

subject

to

a

certain

minimum

transfer

amount

threshold

before

a

transfer

is

required,

which

is

determined

at

the

close

of

business

of

the

Fund.

Any

additional

required

collateral

is

delivered

to/pledged

by

the

Fund

on

the

next

business

day.

Typically,

the

counterparty

is

not

permitted

to

sell,

re-pledge

or

use

cash

and

non-cash

collateral

it

receives.

The

Fund

generally

agrees

not

to

use

non-cash

collateral

that

it

receives

but

may,

absent

default

or

certain

other

circumstances

defined

in

the

underlying

ISDA

Master

Agreement,

be

permitted

to

use

cash

collateral

received.

In

such

cases,

interest

may

be

paid

pursuant

to

the

collateral

arrangement

with

the

counterparty.

To

the

extent

amounts

due

to

the

Fund

from the

counterparties

are

not

fully

collateralized, the

Fund bears

the

risk

of

loss

from

counterparty

non-performance.

Likewise,

to

the

extent

the

Fund

has

delivered

collateral

to

a

counterparty

and

stands

ready

to

perform

under

the

terms

of

its

agreement

with

such

counterparty, the

Fund bears the

risk

of

loss

from

a

counterparty

in

the

amount

of

the

value

of

the

collateral

in

the

event

the

counterparty

fails

to

return

such

collateral.

Based

on

the

terms

of

agreements,

collateral

may

not

be

required

for

all

derivative

contracts.

For

financial

reporting

purposes,

the

Fund

does

not

offset

derivative

assets

and

derivative

liabilities

that

are

subject

to

netting

arrangements,

if

any,

in

the

Consolidated

Statement

of

Assets

and

Liabilities.

INCOME

TAX

INFORMATION 

It

is

the

Fund’s

policy

to

comply

with

the

requirements

of

the

Internal

Revenue

Code

of

1986,

as

amended,

applicable

to

regulated

investment

companies,

and

to

distribute

substantially

all

of

its

taxable

income

to

its

shareholders.

Therefore,

no

U.S.

federal

income

tax

provision

is

required. 

The

Fund

files

U.S.

federal

and

various

state

and

local

tax

returns.

No

income

tax

returns

are

currently

under

examination.

The

statute

of

limitations

on

the

Fund’s

U.S.

federal

tax

returns

generally

remains

open

for

a

period

of

three

years

after

they

are

filed.

The

statutes

of

limitations

on

the

Fund’s

state

and

local

tax

returns

may

remain

open

for

an

additional

year

depending

upon

the

jurisdiction. 

Management

has

analyzed

tax

laws

and

regulations

and

their

application

to

the Fund

as

of

December

31,

2022,

inclusive

of

the

open

tax

return

years,

and

does

not

believe

that

there

are

any

uncertain

tax

positions

that

require

recognition

of

a

tax

liability

in

the

Fund’s

consolidated

financial

statements.

U.S.

GAAP

requires

that

certain

components

of

net

assets

be

adjusted

to

reflect

permanent

differences

between

financial

and

tax

reporting.

These

reclassifications

have

no

effect

on

net

assets

or

NAVs

per

share.

As

of

period

end,

permanent

differences

attributable

to

income

recognized

from

the

Fund’s

wholly

owned

subsidiary

were

reclassified

to

the

following

accounts:

The

tax

character

of

distributions

paid

was

as

follows: 

As

of

December

31,

2022,

the

tax

components

of

accumulated earnings

(loss) were

as

follows:  

(a)

The

difference

between

book-basis

and

tax-basis

net

unrealized

gains

(losses)

was

attributable

primarily

to

the

tax

deferral

of

losses

on

wash

sales

and

straddles,

amortization

methods

of

premiums

on

fixed

income

securities

and

inflation

rate

caps,

the

realization

for

tax

purposes

of

unrealized

gains

(losses)

on

certain

futures

and

foreign

currency

exchange

contracts,

the

accrual

of

income

on

securities

in

default,

the

accounting

for

swap

agreements

and

investments

in

a

wholly

owned

subsidiary.

(b)

The

Fund

has

elected

to

defer

certain

qualified

late-year

losses

and

recognize

such

losses

in

the

next

taxable

year.

BANK

BORROWINGS 

The

Trust, on

behalf

of

the

Fund,

along

with

certain

other

funds

managed

by

the

Manager

and

its

affiliates

(“Participating

Funds”), are

a

party

to

a

364-day,

$2.50

billion

credit

agreement

with

a

group

of

lenders.

Under

this

agreement,

the

Fund

may

borrow

to

fund

shareholder

redemptions.

Excluding

commitments

designated

for

certain

individual

funds,

the

Participating

Funds,

including

the

Fund,

can

borrow

up

to

an

aggregate

commitment

amount

of

$1.75

billion

at

any

time

outstanding,

subject

to

asset

coverage

and

other

limitations

as

specified

in

the

agreement.

The

credit

agreement

has

the

following

terms:

a

fee

of

0.10%

per

annum

on

unused

commitment

amounts

and

interest

at

a

rate

equal

to

the

higher

of

(a)

Overnight

Bank

Funding

Rate

(“OBFR”)

(but,

in

any

event,

not

less

than

0.00%)

on

the

date

the

loan

is

made

plus

0.80%

per

annum,

(b)

the

Fed

Funds

rate

(but,

in

any

event,

not

less

than

0.00%)

in

effect

from

time

to

time

plus

0.80%

per

annum

on

amounts

borrowed

or

(c)

the

sum

of

(x)

Daily

Simple

Secured

Overnight

Financing

Rate

(“SOFR”)

(but,

in

any

event,

not

less

than

0.00%)

on

the

date

the

loan

is

made

plus

0.10%

and

(y)

0.80%

per

annum. The

agreement

expires

in

April

2023

unless

extended

or

renewed. These

fees

were

allocated

among

such

funds

based

upon

portions

of

the

aggregate

commitment

available

to

them

and

relative

net

assets

of

Participating

Funds.

During

the

year ended

December

31,

2022,

the

Fund

did

not

borrow

under

the

credit

agreement.

10.

 PRINCIPAL

RISKS 

In

the

normal

course

of

business,

the

Fund

invests

in

securities

or

other

instruments

and

may

enter

into

certain

transactions,

and

such

activities

subject

the

Fund

to

various

risks,

including

among

others,

fluctuations

in

the

market

(market

risk)

or

failure

of

an

issuer

to

meet

all

of

its

obligations.

The

value

of

securities

or

other

instruments

may

also

be

affected

by

various

factors,

including,

without

limitation:

(i)

the

general

economy;

(ii)

the

overall

market

as

well

as

local,

regional

or

global

political

and/or

social

instability;

(iii)

regulation,

taxation

or

international

tax

treaties

between

various

countries;

or

(iv)

currency,

interest

rate

and

price

fluctuations.

Local,

regional

or

global

events

such

as

war,

acts

of

terrorism,

the

spread

of

infectious

illness

or

other

public

health

issues,

recessions,

or

other

events

could

have

a

significant

impact

on

the

Fund

and its

investments.

The

Fund’s

prospectus

provides

details

of

the

risks

to

which

the

Fund

is

subject. 

Market Risk:

The

Fund

may

be

exposed

to

prepayment

risk,

which

is

the

risk

that

borrowers

may

exercise

their

option

to

prepay

principal

earlier

than

scheduled

during

periods

of

declining

interest

rates,

which

would

force

the

Fund

to

reinvest

in

lower

yielding

securities. The

Fund

may

also

be

exposed

to

reinvestment

risk,

which

is

the

risk

that

income

from

the

Fund’s

portfolio

will

decline

if

the Fund

invests

the

proceeds

from

matured,

traded

or

called

fixed-income

securities

at

market

interest

rates

that

are

below

the

Fund

portfolio’s

current

earnings

rate.

Infectious

Illness

Risk:

An

outbreak

of

an

infectious

illness,

such

as

the

COVID-19

pandemic,

may

adversely

impact

the

economies

of

many

nations

and

the

global

economy,

and

may

impact

individual

issuers

and

capital

markets

in

ways

that

cannot

be

foreseen.

An

infectious

illness

outbreak

may

result

in,

among

other

things,

closed

international

borders,

prolonged

quarantines,

supply

chain

disruptions,

market

volatility

or

disruptions

and

other

significant

economic,

social

and

political

impacts.

Valuation

Risk:

The

market

values

of

equities,

such

as

common

stocks

and

preferred

securities

or

equity

related

investments,

such

as

futures

and

options,

may

decline

due

to

general

market

conditions

which

are

not

specifically

related

to

a

particular

company.

They

may

also

decline

due

to

factors

which

affect

a

particular

industry

or

industries. The

Fund

may

invest

in

illiquid

investments.

An

illiquid

investment

is

any

investment

that the

Fund

reasonably

expects

cannot

be

sold

or

disposed

of

in

current

market

conditions

in

seven

calendar

days

or

less

without

the

sale

or

disposition

significantly

changing

the

market

value

of

the

investment. The

Fund

may

experience

difficulty

in

selling

illiquid

investments

in

a

timely

manner

at

the

price

that it

believes

the

investments

are

worth.

Prices

may

fluctuate

widely

over

short

or

extended

periods

in

response

to

company,

market

or

economic

news.

Markets

also

tend

to

move

in

cycles,

with

periods

of

rising

and

falling

prices.

This

volatility

may

cause

the

Fund’s

NAV

to

experience

significant

increases

or

decreases

over

short

periods

of

time.

If

there

is

a

general

decline

in

the

securities

and

other

markets,

the

NAV

of the

Fund

may

lose

value,

regardless

of

the

individual

results

of

the

securities

and

other

instruments

in

which the

Fund

invests. 

Counterparty

Credit

Risk:

The

Fund

may

be

exposed

to

counterparty

credit

risk,

or

the

risk

that

an

entity

may

fail

to

or

be

unable

to

perform

on

its

commitments

related

to

unsettled

or

open

transactions,

including

making

timely

interest

and/or

principal

payments

or

otherwise

honoring

its

obligations.

The

Fund

manages

counterparty

credit

risk

by

entering

into

transactions

only

with

counterparties

that

the

Manager

believes

have

the

financial

resources

to

honor

their

obligations

and

by

monitoring

the

financial

stability

of

those

counterparties.

Financial

assets,

which

potentially

expose

the

Fund

to

market,

issuer

and

counterparty

credit

risks,

consist

principally

of

financial

instruments

and

receivables

due

from

counterparties.

The

extent

of

the

Fund’s

exposure

to

market,

issuer

and

counterparty

credit

risks

with

respect

to

these

financial

assets

is

approximately

their

value

recorded

in

the

Consolidated

Statement

of

Assets

and

Liabilities,

less

any

collateral

held

by

the

Fund. 

A

derivative

contract

may

suffer

a

mark-to-market

loss

if

the

value

of

the

contract

decreases

due

to

an

unfavorable

change

in

the

market

rates

or

values

of

the

underlying

instrument.

Losses

can

also

occur

if

the

counterparty

does

not

perform

under

the

contract.

For

OTC

options

purchased,

the

Fund

bears

the

risk

of

loss

in

the

amount

of

the

premiums

paid

plus

the

positive

change

in

market

values

net

of

any

collateral

held

by

the

Fund

should

the

counterparty

fail

to

perform

under

the

contracts.

Options

written

by

the

Fund

do

not

typically

give

rise

to

counterparty

credit

risk,

as

options

written

generally

obligate

the

Fund,

and

not

the

counterparty,

to

perform.

The

Fund

may

be

exposed

to

counterparty

credit

risk

with

respect

to

options

written

to

the

extent

the

Fund

deposits

collateral

with

its

counterparty

to

a

written

option. 

With

exchange-traded

options

purchased

and

exchange-traded

futures

and

centrally

cleared

swaps,

there

is

less

counterparty

credit

risk

to

the

Fund

since

the

exchange

or

clearinghouse,

as

counterparty

to

such

instruments,

guarantees

against

a

possible

default.

The

clearinghouse

stands

between

the

buyer

and

the

seller

of

the

contract;

therefore,

credit

risk

is

limited

to

failure

of

the

clearinghouse.

While

offset

rights

may

exist

under

applicable

law, the

Fund

does

not

have

a

contractual

right

of

offset

against

a

clearing

broker

or

clearinghouse

in

the

event

of

a

default

(including

the

bankruptcy

or

insolvency).

Additionally,

credit

risk

exists

in exchange-traded

futures

and

centrally

cleared

swaps

with

respect

to

initial

and

variation

margin

that

is

held

in

a

clearing

broker’s

customer

accounts.

While

clearing

brokers

are

required

to

segregate

customer

margin

from

their

own

assets,

in

the

event

that

a

clearing

broker

becomes

insolvent

or

goes

into

bankruptcy

and

at

that

time

there

is

a

shortfall

in

the

aggregate

amount

of

margin

held

by

the

clearing

broker

for

all

its

clients,

typically

the

shortfall

would

be

allocated

on

a

pro

rata

basis

across

all

the

clearing

broker’s

customers,

potentially

resulting

in

losses

to

the

Fund.

Concentration

Risk:

 A

diversified

portfolio,

where

this

is appropriate

and

consistent

with

a

fund’s

objectives,

minimizes

the

risk

that

a

price

change

of

a

particular

investment

will

have

a

material

impact

on

the

NAV

of

a

fund.

The

investment

concentrations

within

the

Fund’s

portfolio

are

disclosed

in

its Consolidated

Schedule

of

Investments.

The

Fund

invests

a

significant

portion

of

its

assets

in fixed-income securities and/or uses

derivatives tied

to

the

fixed-income

markets.

Changes

in

market

interest

rates

or

economic

conditions

may affect

the

value

and/or

liquidity

of

such investments.

Interest

rate

risk

is

the

risk

that

prices

of

bonds

and

other

fixed-income

securities

will

decrease

as

interest

rates

rise

and

increase

as

interest

rates

fall.

The

Fund

may

be

subject

to

a

greater

risk

of

rising

interest

rates

due

to

the recent

period

of

historically

low

interest rates. The

Federal

Reserve

has

recently

begun

to

raise

the

federal

funds

rate

as

part

of

its

efforts

to

address

inflation.

There

is

a

risk

that

interest

rates

will

continue

to

rise,

which

will

likely

drive

down

the

prices

of

bonds

and

other

fixed-income

securities,

and

could

negatively

impact

the

Fund’s

performance.

Significant

Shareholder

Redemption

Risk:

Certain

shareholders

may

own

or

manage

a

substantial

amount

of

fund

shares

and/or

hold

their

fund

investments

for

a

limited

period

of

time.

Large

redemptions

of

fund

shares

by

these

shareholders

may

force

a

fund

to

sell

portfolio

securities,

which

may

negatively

impact

the

fund’s

NAV,

increase

the

fund’s

brokerage

costs,

and/or

accelerate

the

realization

of

taxable

income/gains

and

cause

the

fund

to

make

additional

taxable

distributions

to

shareholders.

LIBOR

Transition

Risk:

The

United

Kingdom’s

Financial

Conduct

Authority

announced

a phase

out of

the

London

Interbank

Offered

Rate

(“LIBOR”).

Although

many

LIBOR

rates

ceased

to

be

published

or

no

longer are

representative

of

the

underlying

market

they

seek

to

measure

after

December

31,

2021,

a

selection

of

widely

used

USD

LIBOR

rates

will

continue

to

be

published

through

June

2023

in

order

to

assist

with

the

transition.

The

Fund

may

be

exposed

to

financial

instruments

tied

to

LIBOR

to

determine

payment

obligations,

financing

terms,

hedging

strategies

or

investment

value.

The

transition

process

away

from

LIBOR

might

lead

to

increased

volatility

and

illiquidity

in

markets

for,

and

reduce

the

effectiveness

of

new

hedges

placed

against

instruments

whose

terms

currently

include

LIBOR.

The

ultimate

effect

of

the

LIBOR

transition

process

on

the

Fund

is

uncertain.

Opinion

on

the

Financial

Statements

and

Financial

Highlights

We

have

audited

the

accompanying

consolidated

statement

of

assets

and

liabilities

of

BlackRock

Inflation

Protected

Bond

Portfolio

of

BlackRock

Funds

V

(the

“Fund”),

including

the

consolidated

schedule

of

investments,

as

of

December

31,

2022,

the

related

consolidated

statements

of

operations

and

cash

for

the

then

the

consolidated

of

ended,

the

consolidated

financial

highlights

for

each

of

the

five

years

in

the

period

then

ended,

and

the

related

notes.

In

our

opinion,

the

financial

statements

and

financial

highlights

present

fairly,

in

all

material

respects,

the

financial

position

of

the

Fund

as

of

December

31,

2022,

and

the

results

of

its

operations

and

its

cash

for

the

the

in

its

for

and

the

for

each

in

the

period

then

ended,

in

conformity

with

accounting

principles

generally

accepted

in

the

United

States

of

America.

Basis

for

Opinion

These

financial

statements

and

financial

highlights

are

the

responsibility

of

the

Fund’s

management.

Our

responsibility

is

to

express

an

opinion

on

the

Fund’s

financial

statements

and

financial

highlights

based

on

our

audits.

We

are

a

public

accounting

firm

registered

with

the

Public

Company

Accounting

Oversight

Board

(United

States)

(PCAOB)

and

are

required

to

be

independent

with

respect

to

the

Fund

in

accordance

with

the

U.S.

federal

securities

laws

and

the

applicable

rules

and

regulations

of

the

Securities

and

Exchange

Commission

and

the

PCAOB.

We

conducted

our

audits

in

accordance

with

the

standards

of

the

PCAOB.

Those

standards

require

that

we

plan

and

perform

the

audit

to

obtain

reasonable

assurance

about

whether

the

financial

statements

and

financial

highlights

are

free

of

material

misstatement,

whether

due

to

error

or

fraud.

The

Fund

is

not

required

to

have,

nor

were

we

engaged

to

perform,

an

audit

of

its

internal

control

over

financial

reporting.

As

part

of

our

audits

we

are

required

to

obtain

an

understanding

of

internal

control

over

financial

reporting

but

not

for

the

purpose

of

expressing

an

opinion

on

the

effectiveness

of

the

Fund’s

internal

control

over

financial

reporting.

Accordingly,

we

express

no

such

opinion.

Our

audits

included

performing

procedures

to

assess

the

risks

of

material

misstatement

of

the

financial

statements

and

financial

highlights,

whether

due

to

error

or

fraud,

and

performing

procedures

that

respond

to

those

risks.

Such

procedures

included

examining,

on

a

test

basis,

evidence

regarding

the

amounts

and

disclosures

in

the

financial

statements

and

financial

highlights.

Our

audits

also

included

evaluating

the

accounting

principles

used

and

significant

estimates

made

by

management,

as

well

as

evaluating

the

overall

presentation

of

the

financial

statements

and

financial

highlights.

Our

procedures

included

confirmation

of

securities

owned

as

of

December

31,

2022,

by

correspondence

with

custodians

or

counterparties;

when

replies

were

not

received,

we

performed

other

auditing

procedures.

We

believe

that

our

audits

provide

a

reasonable

basis

for

our

opinion.

Statement

Regarding

Liquidity

Risk

Management

Program

In

compliance

with

Rule

22e-4

under

the

Investment

Company

Act

of

1940,

as

amended

(the

“Liquidity

Rule”),

BlackRock

Funds

V

(the

“Trust”)

has

adopted

and

implemented

a

liquidity

risk

management

program

(the

“Program”)

for

BlackRock

Inflation

Protected

Bond

Portfolio

(the

“Fund”),

a

series

of

the

Trust,

which

is

reasonably

designed

to

assess

and

manage

the

Fund’s

liquidity

risk.

The

Board

of

Trustees

(the

“Board”)

of

the

Trust,

on

behalf

of

the

Fund(s),

met

on

November

10-11,

2022

(the

“Meeting”)

to

review

the

Program.

The

Board

previously

appointed

BlackRock

Advisors,

LLC,

the

investment

adviser

to

the

Fund,

as

the

program

administrator

for

the

Fund’s

Program.

BlackRock

also

previously

delegated

oversight

of

the

Program

to

the

40

Act

Liquidity

Risk

Management

Committee

(the

“Committee”).

At

the

Meeting,

the

Committee,

on

behalf

of

BlackRock,

provided

the

Board

with

a

report

that

addressed

the

operation

of

the

Program

and

assessed

its

adequacy

and

effectiveness

of

implementation,

including

the

management

of

the

Fund’s

Highly

Liquid

Investment

Minimum

(“HLIM”)

where

applicable,

and

any

material

changes

to

the

Program

(the

“Report”).

The

Report

covered

the

period

from

October

1,

2021

through

September

30,

2022

(the

“Program

Reporting

Period”).

The

Report

described

the

Program’s

liquidity

classification

methodology

for

categorizing

the

Fund’s

investments

(including

derivative

transactions)

into

one

of

four

liquidity

buckets.

It

also

referenced

the

methodology

used

by

BlackRock

to

establish

the

Fund’s

HLIM

and

noted

that

the

Committee

reviews

and

ratifies

the

HLIM

assigned

to

the

Fund

no

less

frequently

than

annually.

The

Report

also

discussed

notable

events

affecting

liquidity

over

the

Program

Reporting

Period,

including

the

imposition

of

capital

controls

in

certain

countries.

The

Report

noted

that

the

Program

complied

with

the

key

factors

for

consideration

under

the

Liquidity

Rule

for

assessing,

managing

and

periodically

reviewing

the

Fund’s

liquidity

risk,

as

follows:

a)

The

Fund’s

investment

strategy

and

liquidity

of

portfolio

investments

during

both

normal

and

reasonably

foreseeable

stressed

conditions

.

During

the

Program

Reporting

Period,

the

Committee

reviewed

whether

the

Fund’s

strategy

is

appropriate

for

an

open-end

fund

structure

with

a

focus

on

funds

with

more

significant

and

consistent

holdings

of

less

liquid

and

illiquid

assets.

The

Committee

also

factored

a

fund’s

concentration

in

an

issuer

into

the

liquidity

classification

methodology

by

taking

issuer

position

sizes

into

account.

Where

a

fund

participated

in

borrowings

for

investment

purposes

(such

as

tender

option

bonds

or

reverse

repurchase

agreements),

such

borrowings

were

factored

into

the

Program’s

calculation

of

a

fund’s

liquidity

bucketing.

A

fund’s

derivative

exposure

was

also

considered

in

such

calculation.

b)

Short-term

and

long-term

cash

flow

projections

during

both

normal

and

reasonably

foreseeable

stressed

conditions

.

During

the

Program

Reporting

Period,

the

Committee

reviewed

historical

redemption

activity

and

used

this

information

as

a

component

to

establish

the

Fund’s

reasonably

anticipated

trading

size

utilized

for

liquidity

classifications.

The

Fund

has

adopted

an

in-kind

redemption

policy

which

may

be

utilized

to

meet

larger

redemption

requests.

The

Committee

may

also

take

into

consideration

a

fund’s

shareholder

ownership

concentration

(which,

depending

on

product

type

and

distribution

channel,

may

or

may

not

be

available),

a

fund’s

distribution

channels,

and

the

degree

of

certainty

associated

with

a

fund’s

short-term

and

long-term

cash

flow

projections.

c)

Holdings

of

cash

and

cash

equivalents,

as

well

as

borrowing

arrangements

.

The

Committee

considered

the

terms

of

the

credit

facility

committed

to

the

Fund,

the

financial

health

of

the

institution

providing

the

facility

and

the

fact

that

the

credit

facility

is

shared

among

multiple

funds

(including

that

a

portion

of

the

aggregate

commitment

amount

is

specifically

designated

for

BlackRock

Floating

Rate

Income

Portfolio,

a

series

of

BlackRock

Funds

V,

and

BlackRock

Floating

Rate

Loan

ETF,

a

series

of

BlackRock

ETF

Trust

II).

The

Committee

also

considered

other

types

of

borrowing

available

to

the

funds,

such

as

the

ability

to

use

reverse

repurchase

agreements

and

interfund

lending,

as

applicable.

There

were

no

material

changes

to

the

Program

during

the

Program

Reporting

Period

other

than

the

enhancement

of

certain

model

components

in

the

Program’s

classification

methodology.

The

Report

provided

to

the

Board

stated

that

the

Committee

concluded

that

based

on

the

operation

of

the

functions,

as

described

in

the

Report,

the

Program

is

operating

as

intended

and

is

effective

in

implementing

the

requirements

of

the

Liquidity

Rule.

Item 2 – Code of Ethics –

The registrant (or the “Fund”) has adopted a code of ethics, as of the end of the period covered by this report, applicable to the registrant’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions.  During the period covered by this report, the code of ethics was amended to update certain information and to make other non-material changes.  During the period covered by this report, there have been no waivers granted under the code of ethics. The

registrant undertakes to provide a copy of the code of ethics to any person upon request, without charge, who calls 1-800-441-7762.

Item 3 – Audit Committee Financial Expert – The registrant’s board of directors (the “board of directors”), has determined that (i) the registrant has the following audit committee financial experts serving on its audit committee and (ii) each audit committee financial expert is independent:

               Frank J. Fabozzi

Lorenzo A. Flores
Catherine A. Lynch

Under applicable securities laws, a person determined to be an audit committee financial expert will not be deemed an “expert” for any purpose, including without limitation for the purposes of Section 11 of the Securities Act of 1933, as a result of being designated or identified as an audit committee financial expert.  The designation or identification of a person as an audit committee financial expert does not impose on such person any duties, obligations, or liabilities greater than the duties, obligations, and liabilities imposed on such person as a member of the audit committee and board of directors in the absence of such designation or identification.  The designation or identification of a person as an audit committee financial expert does not affect the duties, obligations, or liability of any other member of the audit committee or board of directors.

The following table presents fees billed by D&T that were required to be approved by the registrant’s audit committee (the “Committee”) for services that relate directly to the operations or financial reporting of the Fund and that are rendered on behalf of BlackRock Advisors, LLC (the “Investment Adviser” or “BlackRock”) and entities controlling, controlled by, or under common control with BlackRock (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) that provide ongoing services to the Fund (“Affiliated Service Providers”):

	Current Fiscal Year End	Previous Fiscal Year End
(b) Audit-Related Fees1	$0	$0

Non-audit fees of $2,098,000 and $2,032,000 for the current fiscal year and previous fiscal year, respectively, were paid to the Fund’s principal accountant in their entirety by BlackRock, in connection with services provided to the Affiliated Service Providers of the Fund and of certain other funds sponsored and advised by BlackRock or its affiliates for a service organization review and an accounting research tool subscription.  These amounts represent aggregate fees paid by BlackRock and were not allocated on a per fund basis.

The Committee has adopted policies and procedures with regard to the pre-approval of services.  Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee.  The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the Investment Adviser and Affiliated Service Providers that relate directly to the operations and the financial reporting of the registrant.  Certain of these non-audit services that the Committee believes are (a) consistent with the SEC’s auditor independence rules and (b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis (“general pre-approval”).  The term of any general pre-approval is 12 months from the date of the pre-approval, unless the Committee provides for a different period.  Tax or other non-audit services provided to the registrant which have a direct impact on the operations or financial reporting of the registrant will only be deemed pre-approved provided that any individual project does not exceed $10,000 attributable to the registrant or $50,000 per project.  For this purpose, multiple projects will be aggregated to determine if they exceed the previously mentioned cost levels.

                        Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services).  The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting.  At this meeting, an analysis of such services is presented to the Committee for ratification.  The Committee may delegate to the Committee Chairman the authority to approve the provision of and fees for any specific engagement of permitted non-audit services, including services exceeding pre-approved cost levels.

(e)(2)  None of the services described in each of Items 4(b) through (d) were approved by the Committee pursuant to the de minimis exception in paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not Applicable

(g)

The aggregate non-audit fees, defined as the sum of the fees shown under “Audit-Related Fees,” “Tax Fees” and “All Other Fees,” paid to the accountant for services rendered by the accountant to the registrant, the Investment Adviser and the Affiliated Service Providers were:

Entity Name	Current Fiscal Year End	Previous Fiscal Year End
BlackRock Inflation Protected Bond Portfolio	$22,475	$21,410

              Additionally, the amounts billed by D&T in connection with services provided to the Affiliated Service Providers of the Fund and of other funds sponsored and advised by BlackRock or its affiliates during the current and previous fiscal years for a service organization review and an accounting research tool subscription were:

Current Fiscal Year End	Previous Fiscal Year End
$2,098,000	$2,032,000

              These amounts represent aggregate fees paid by BlackRock and were not allocated on a per fund basis.

              (h) The Committee has considered and determined that the provision of non-audit services that were rendered to the Investment Adviser and

the Affiliated Service Providers

that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant’s independence.
