Dear

Shareholder,

The

12-month

reporting

period

as

of

September

30,

2020

has

been

a

time

of

sudden

change

in

global

financial

markets,

as

the

emergence

and

spread

of

the

coronavirus

(or

“COVID-19”)

led

to

a

vast

disruption

in

the

global

economy

and

financial

markets.

Prior

to

the

outbreak

of

the

virus,

U.S.

equities

and

bonds

both

delivered

impressive

returns,

despite

fears

and

doubts

about

the

economy

that

were

ultimately

laid

to

rest

with

unprecedented

monetary

stimulus

and

a

sluggish

yet

resolute

performance

from

the

U.S.

economy.

But

as

the

threat

from

the

coronavirus

became

more

apparent

throughout

February

and

March

2020,

countries

around

the

world

took

economically

disruptive

countermeasures.

Stay-at-home

orders

and

closures

of

non-essential

businesses

became

widespread,

many

workers

were

laid

off,

and

unemployment

claims

spiked,

causing

a

global

recession

and

a

sharp

fall

in

equity

prices.

After

markets

hit

their

lowest

point

during

the

reporting

period

in

late

March

2020,

a

steady

recovery

ensued,

as

businesses

began

to

re-open

and

governments

learned

to

adapt

to

life

with

the

virus.

Equity

prices

continued

to

rise

throughout

the

summer,

fed

by

strong

fiscal

and

monetary

support

and

improving

economic

indicators.

Many

equity

indices

neared

or

surpassed

all-time

highs

in

early

September

2020

before

retreating

amid

concerns

about

a

second

wave

of

infections.

In

the

United

States,

large-capitalization

stocks

advanced,

outperforming

small-capitalization

stocks,

which

gained

only

marginally

during

the

reporting

period.

International

equities

from

developed

economies

were

nearly

flat,

lagging

emerging

market

stocks,

which

rebounded

sharply.

During

the

market

downturn,

the

performance

of

different

types

of

fixed-income

securities

initially

diverged

due

to

a

reduced

investor

appetite

for

risk.

U.S.

Treasuries

benefited

from

the

risk-off

environment,

and

posted

solid

returns,

as

the

10-year

U.S.

Treasury

yield

(which

is

inversely

related

to

bond

prices)

touched

an

all-time

low.

In

the

corporate

bond

market,

support

from

the

U.S.

Federal

Reserve

(the

“Fed”)

assuaged

credit

concerns

and

both

investment-grade

and

high-yield

bonds

recovered

to

post

positive

returns.

The

Fed

reduced

short-term

interest

rates

in

late

2019

to

support

slowing

economic

growth.

After

the

coronavirus

outbreak,

the

Fed

instituted

an

additional

two

emergency

rate

cuts,

pushing

short-term

interest

rates

close

to

zero.

To

stabilize

credit

markets,

the

Fed

also

implemented

a

new

bond-buying

program,

as

did

several

other

central

banks

around

the

world,

including

the

European

Central

Bank

and

the

Bank

of

Japan.

Looking

ahead,

while

coronavirus-related

disruptions

have

clearly

hindered

worldwide

economic

growth,

we

believe

that

the

global

expansion

is

likely

to

continue

as

economic

activity

resumes.

Several

risks

remain,

however,

including

a

potential

resurgence

of

the

coronavirus

amid

loosened

restrictions,

policy

fatigue

among

governments

already

deep

into

deficit

spending,

and

structural

damage

to

the

financial

system

from

lengthy

economic

interruptions.

Overall,

we

favor

a

moderately

positive

stance

toward

risk,

and

in

particular

toward

credit

given

the

extraordinary

central

bank

measures

taken

in

recent

months.

This

support

extends

beyond

investment-grade

corporates

and

into

high-yield,

leading

to

attractive

opportunities

in

that

end

of

the

market.

We

believe

that

international

diversification

and

a

focus

on

sustainability

can

help

provide

portfolio

resilience,

and

the

disruption

created

by

the

coronavirus

appears

to

be

accelerating

the

shift

toward

sustainable

investments.

We

remain

neutral

on

equities

overall

while

favoring

European

stocks,

which

are

poised

for

cyclical

upside

as

re-openings

continue.

In

this

environment,

investors

need

to

think

globally,

extend

their

scope

across

a

broad

array

of

asset

classes,

and

be

nimble

as

market

conditions

change.

We

encourage

you

to

talk

with

your

financial

advisor

and

visit

blackrock.com

for

further

insight

about

investing

in

today’s

markets.

Overview

For

the

Six-Month

Period

Ended

September

30,

2020

2020

BlackRock

Semi-Annual

Report

to

Shareholders

4

During

the

six-period

ended

September

30,

2020,

the

Federal

Open

Market

Committee

(the

“FOMC”

or,

the

“Committee”)

left

the

range

for

the

Federal

Funds

target

rate

unchanged

at

0.00%

-0.25%,

noting

at

the

FOMC’s

September

16,

2020

meeting

that

the

ongoing

public

health

crisis

“poses

considerable

risks

to

the

economic

outlook

over

the

medium

term.”

This

statement

following

the

Committee

meeting

reflected

the

updates

previously

announced

on

August

27,

2020

to

the

Committee’s

Statement

on

Longer-Run

Goals

and

Monetary

Policy.

In

particular,

the

FOMC

noted

that

it

“expects

it

will

be

appropriate

to

maintain

this

target

range

until

labor

market

conditions

have

reached

levels

consistent

with

the

Committee's

assessments

of

maximum

employment

and

inflation

has

risen

to

two

percent

and

is

on

track

to

moderately

exceed

two

percent

for

some

time.”

The

Committee

also

acknowledged

that

“over

coming

months

the

Federal

Reserve

will

increase

its

holdings

of

Treasury

securities

and

agency

mortgage-backed

securities

at

least

at

the

current

pace

to

sustain

smooth

market

functioning

and

help

foster

accommodative

financial

conditions,

thereby

supporting

the

flow

of

credit

to

households

and

businesses.”

The

so-called

“dot

plot”

reflected

no

change

in

the

FOMC’s

median

interest

rate

forecast

through

2023.

Yields

on

three-month

Treasury

bills

(“T-bills”)

ended

the

third

quarter

of

2020

below

0.10%,

down

about

0.04%

-

0.05%

compared

to

early

in

the

period.

Net

new

T-bill

supply

contracted

about

$51

billion

during

the

third

quarter.

We

believe

both

the

timing

and

amount

of

T-bill

issuance

through

the

balance

of

the

year

will

likely

remain

largely

contingent

on

whether

consensus

can

be

reached

in

Washington

D.C.

to

pass

any

additional

fiscal

stimulus

measures

at

the

Federal

level.

In

any

case,

we

expect

net

new

T-bill

supply

in

the

fourth

quarter

of

2020

to

be

tempered

relative

to

earlier

in

the

year

given

an

elevated

Treasury

General

Account

balance

at

the

Fed

of

approximately

$1.8

trillion

as

of

September

30,

and

an

expected

bias

in

Treasury

issuance

toward

longer-dated

coupons.

Credit

spreads

generally

tightened

during

the

third

quarter

with

the

three-month

London

Interbank

Offered

Rate

overnight

indexed

swap

spread

—a

gauge

of

stress

in

the

financial

system—

contracting

from

0.24%

at

June

30,

2020

to

0.16%

by

late

September.

In

the

last

year,

the

previous

low

point

for

this

spread

was

0.12%.

Our

strategic

allocations

in

September

were

broadly

consistent

with

the

positioning

for

the

majority

of

the

summer

months.

In

setting

strategy,

we

maintained

a

bias

toward

higher-quality

issuers

of

commercial

paper

and

U.S.

dollar-denominated

certificates

of

deposit

when

adding

investments

in

three-to

six-month

tenors.

When

analyzing

overall

risk

markets

in

September,

we

noticed

significantly

elevated

levels

of

volatility

priced

in

the

equity

options

markets.

At

the

same

time,

we

believe

that

short-term

credit

valuations

are

quite

expensive.

As

a

result,

we

believe

it

is

prudent

at

the

moment

to

build

slightly

elevated

liquidity

buffers

to

prime

funds

to

mitigate

against

potential

volatility

associated

with

the

upcoming

U.S.

presidential

election,

and

U.S.-China

trade

disputes

amongst

other

such

risks.

As

such,

we

have

increased

our

exposure

to

Treasuries

and

securities

that

mature

within

six

months.

We

still

seek

selective

opportunities

to

help

preserve

yield

further

out

the

curve

with

fixed

and

floating

rate

securities

that

we

believe

represent

convincing

relative

value.

With

the

Fed

continuing

its

pledge

support

to

markets,

front-end

credit

markets

have

remained

calm.

We

continue

to

monitor

credit

ratings

activity

and

are

cautious

of

the

uncertainty

that

lies

ahead

when

setting

strategy.

As

a

result,

we

continue

to

be

conservative

in

sectors

that

are

subject

to

heightened

risk

of

downgrade.

Our

focus

on

liquidity

means

we

have

maintained

elevated

levels

of

liquidity

relative

to

historical

positioning.

With

respect

to

BlackRock

Wealth

Liquid

Environmentally

Aware

Fund

(the

“Fund”),

our

outlook

for

leaders

in

the

environmental

pillar

of

the

environmental,

social

and

governance

(“ESG”)

space

shows

signs

of

being

well

positioned

to

weather

the

economic

shifts

taking

place.

We

continue

to

believe

that

incorporating

ESG

risks

into

our

fundamental

credit

assessment

may

result

in

better

risk-adjusted

returns.

Although

credit

markets

have

remained

calm,

we

continue

to

keep

an

eye

on

ratings

activity

and

maintain

a

conservative

strategy

due

to

the

uncertainty

ahead.

As

a

result,

we

have

remained

cautious

in

sectors

that

are

subject

to

heightened

risk

of

downgrade

and

continue

to

seek

to

position

the

Fund

conservatively.

Disclosure

of

Expenses

Shareholders

of

the

Fund

may

incur

the

following

charges:

(a)

transactional

expenses;

and

(b)

operating

expenses,

including

investment

advisory

fees,

administration

fees,

service

and

distribution

fees

and

other

fund

expenses.

The

expense

example

shown

below

(which

is

based

on

a

hypothetical

investment

of

$1,000

invested

on

April

1,

2020

and

held

through

September

30,

2020

)

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.

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.

2a-7

under

the

1940

Act.

The

Board

of

Trustees

of

the

Trust (the

"Board")

is

permitted

to

impose

a

liquidity

fee

of

up

to

2%

of

the

value

of

shares

redeemed

or

temporarily

restrict

redemptions

from

the

Fund

for

up

to

10

business

days

during

a

90

day

period,

in

the

event

that

the

Fund’s

weekly

liquid

fall

below

certain

thresholds.

On

February

the

Board

approved

a

change

in

the

name

of

the

Fund,

effective

as

of

May

to

BlackRock

Wealth

Liquid

Environmentally

The

Fund,

together

with

certain

other

registered

investment

companies

advised

by

BlackRock

Advisors,

LLC

(the

"Manager") or

its

affiliates,

is

included

in

a

equity,

multi-asset,

index

and

money

market

funds

referred

to

as

the

BlackRock

Multi-Asset

Complex.

SIGNIFICANT

ACCOUNTING

POLICIES

The

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

financial

statements,

disclosure

of

contingent

assets

and

liabilities

at

the

date

of

the

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

on

the

identified

cost

basis.

Interest

income,

including

amortization

and

accretion

of

premiums

and

discounts

on

debt

securities,

is

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.

Distributions:

Distributions

from

net

investment

income

are

declared

daily

and

paid

monthly.

Distributions

of

capital

gains

are

distributed

at

least

annually

and

are

recorded

on

the

ex-dividend

dates.

The

character

and

timing

of

distributions

are

determined

in

accordance

with

U.S.

federal

income

tax

regulations,

which

may

differ

from

U.S.

GAAP

. 

Liquidity

Fees:

Any

liquidity

fees

imposed

on

the

value

of

shares

redeemed

in

the

event

that

the

Fund’s

weekly

liquid

assets

fall

below

certain

thresholds

are

recorded

as

paid-in-capital.

The

liquidity

fees

are

collected

and

retained

by

the

Fund

for

the

benefit

of the

Fund’s

remaining

shareholders. 

Offering

Costs:

Offering

costs

are

amortized

over

a

12-month

period

beginning

with

the

commencement

of

operations

of

a

class

of

shares.

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.

The

Fund

has

an

arrangement

with

its

custodian

whereby

credits

are

earned

on

uninvested

cash

balances,

which

could

be

used

to

reduce

custody

fees

and/or

overdraft

charges.

The

Fund

may

incur

charges

on

overdrafts,

subject

to

certain

conditions.

INVESTMENT

VALUATION

AND

FAIR

VALUE

MEASUREMENTS 

Investment

Valuation

Policies:

 U.S.

GAAP

defines

fair

value

as

the

price

the

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

Fund’s

investments

are

valued

under

the

amortized

cost

method

which

approximates

current

market

value

in

accordance

with

Rule

2a-7

under

the

1940

Act.

Under

this

method,

investments

are

valued

at

cost

when

purchased

and,

thereafter,

a

constant

proportionate

accretion

of

discounts

and

amortization

of

premiums

are

recorded

until

the

maturity

of

the

security.

The

Fund

seeks

to

maintain

its

net

asset

value

(“NAV”)

per

share

at

$1.00,

although

there

is

no

assurance

that

it

will

be

able

to

do

so

on

a

continuing

basis.

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) 

Level

3 —

Unobservable

inputs

based

on

the

best

information

available

in

the

circumstances,

to

the

extent

observable

inputs

are

not

available

(including

the

Global

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. The

categorization

of

a

value

determined

for

financial

instruments

is

based

on

the

pricing

transparency

of

the financial

instruments

and

is

not

necessarily

an

indication

of

the

risks

associated

with

investing

in

those

securities.

SECURITIES

AND

OTHER

INVESTMENTS 

Repurchase

Agreements:

Repurchase

agreements

are

commitments

to

purchase

a

security

from

a

counterparty

who

agrees

to

repurchase

the

same

security

at

a

mutually

agreed

upon

date

and

price.

On

a

daily

basis,

the

counterparty

is

required

to

maintain

collateral

subject

to

the

agreement

and

in

value

no

less

than

the

agreed

upon

repurchase

amount.

Repurchase

agreements

may

be

traded

bilaterally,

in

a

tri-party

arrangement

or

may

be

centrally

cleared

through

a

sponsoring

agent.

Subject

to

the

custodial

undertaking

associated

with

a

tri-party

repurchase

arrangement

and

for

centrally

cleared

repurchase

agreements,

a

third

party

custodian

maintains

accounts

to

hold

collateral

for

the

fund

and

its

counterparties.

Typically,

the

fund

and

counterparty

are

not

permitted

to

sell,

re-pledge

or

use

the

collateral

absent

a

default

by

the

counterparty

or

the

fund,

respectively. 

In

the

event

the

counterparty

defaults

and

the

fair

value

of

the

collateral

declines, the

fund

could

experience

losses,

delays

and

costs

in

liquidating

the

collateral.

Repurchase

agreements

are

entered

into

by

the

fund

under

Master

Repurchase

Agreements

(each,

an

“MRA”).

The

MRA

permits

the

fund,

under

certain

circumstances

including

an

event

of

default

(such

as

bankruptcy

or

insolvency),

to

offset

payables

and/or

receivables

with

collateral

held

by

and/or

posted

to

the

counterparty.

As

a

result,

one

single

net

payment

is

created.

Bankruptcy

or

insolvency

laws

of

a

particular

jurisdiction

may

impose

restrictions

on

or

prohibitions

against

such

a

right

of

offset

in

the

event

of

the

MRA

counterparty’s

bankruptcy

or

insolvency.

Based

on

the

terms

of

the

MRA,

the

fund

receives

securities

as

collateral

with

a

market

value

in

excess

of

the

repurchase

price

at

maturity.

Upon

a

bankruptcy

or

insolvency

of

the

MRA

counterparty,

the

fund

would

recognize

a

liability

with

respect

to

such

excess

collateral.

The

liability

reflects

the

fund’s

obligation

under

bankruptcy

law

to

return

the

excess

to

the

counterparty.

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

fiscal

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

September

30,

2020,

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

financial

statements.

 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. 

Certain

obligations

held

by

the

Fund

have

a

credit

enhancement

or

liquidity

feature

that

may,

under

certain

circumstances,

provide

for

repayment

of

principal

and

interest

on

the

obligation

when

due. These

enhancements,

which

may

include

letters

of

credit,

stand-by

bond

purchase

agreements

and/or

third

party

insurance,

are

issued

by

financial

institutions. The

value

of

the

obligations

may

be

affected

by

changes

in

creditworthiness

of

the

entities

that

provide

the

credit

enhancements

or

liquidity

features. The

Fund

monitors

its

exposure

by

reviewing

the

creditworthiness

of

the

issuers,

as

well

as

the

financial

institutions

issuing

the

credit

enhancements

and

by

limiting

the

amount

of

holdings

with

credit

enhancements

from

one

financial

institution. 

Market

Risk:

Municipal

securities

are

subject

to

the

risk

that

litigation,

legislation

or

other

political

events,

local

business

or

economic

conditions,

credit

rating

downgrades,

or

the

bankruptcy

of

the

issuer

could

have

a

significant

effect

on

an

issuer's

ability

to

make

payments

of

principal

and/or

interest

or

otherwise

affect

the

value

of

such

securities.

Municipal

securities

can

be

significantly

affected

by

political

or

economic

changes,

including

changes

made

in

the

law

after

issuance

of

the

securities,

as

well

as

uncertainties

in

the

municipal

market

related

to,

taxation,

legislative

changes

or

the

rights

of

municipal

security

holders,

including

in

connection

with

an

issuer

insolvency.

Municipal

securities

backed

by

current

or

anticipated

revenues

from

a

specific

project

or

specific

assets

can

be

negatively

affected

by

the

discontinuance

of

the

tax

benefits

supporting

the

project

or

assets

or

the

inability

to

collect

revenues

for

the

project

or

from

the

assets.

Municipal

securities

may

be

less

liquid

than

taxable

bonds,

and

there

may

be

less

publicly

available

information

on

the

financial

condition

of

municipal

security

issuers

than

for

issuers

of

other

securities.

An

outbreak

of

respiratory

disease

caused

by

a

novel

coronavirus

has

developed

into

a

global

pandemic

and

has

resulted

in

closing

borders,

quarantines,

disruptions

to

supply

chains

and

customer

activity,

as

well

as

general

concern

and

uncertainty.

The

impact

of

this

pandemic,

and

other

global

health

crises

that

may

arise

in

the

future,

could

affect

the

economies

of

many

nations,

individual

companies

and

the

market

in

general

in

ways

that

cannot

necessarily

be

foreseen

at

the

present

time.

This

pandemic

may

result

in

substantial

market

volatility

and

may

adversely

impact

the

prices

and

liquidity

of

a

fund's

investments.

The duration

of

this

pandemic

and

its

effects

cannot

be

determined

with

certainty.

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

Statement

of

Assets

and

Liabilities,

less

any

collateral

held

by

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 Schedule

of

Investments.

LIBOR

Transition

Risk:

The

United

Kingdom’s

Financial

Conduct

Authority

announced

a phase

out of

the

London

Interbank

Offered

Rate

(“LIBOR”)

by

the

end

of

2021,

and

it

is

expected

that

LIBOR

will

cease

to

be

published

after

that

time. 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.

(the

met

on

April

7,

2020

(the

“April

and

May

11-13,

2020

(the

advisory

agreement

(the

“Agreement”)

between

the

Trust,

on

behalf

of

BlackRock

Wealth

Liquid

Environmentally

Fund

(the

“Fund”),

a

series

of

the

Trust,

and

BlackRock

Advisors,

LLC

(the

“Manager”

or

“BlackRock”),

the

Trust’s

investment

advisor.

Activities

and

Composition

of

the

Board

On

the

date

of

the

May

Meeting,

the

Board

consisted

of

fourteen

individuals,

twelve

of

whom

were

not

“interested

persons”

of

the

Trust

as

defined

in

the

Investment

Company

Act

of

1940,

as

amended

(the

“1940

Act”)

(the

“Independent

Board

Members”).

The

Board

Members

are

responsible

for

the

oversight

of

the

operations

of

the

Trust

and

perform

the

various

duties

imposed

on

the

directors

of

investment

companies

by

the

1940

Act.

The

Independent

Board

Members

have

retained

independent

legal

counsel

to

assist

them

in

connection

with

their

duties.

The

Chair

of

the

Board

is

an

Independent

Board

Member.

The

Board

has

established

five

standing

committees:

an

Audit

Committee,

a

Governance

and

Nominating

Committee,

a

Compliance

Committee,

a

Performance

Oversight

Committee

and

an

Ad

Hoc

Topics

Committee,

each

of

which

is

chaired

by

an

Independent

Board

Member

and

composed

of

Independent

Board

Members

(except

for

the

Ad

Hoc

Topics

Committee,

which

also

has

one

interested

Board

Member).

The

Agreement

Consistent

with

the

requirements

of

the

1940

Act,

the

Board

considers

the

continuation

of

the

Agreement

on

an

annual

basis.

The

Board

has

four

quarterly

meetings

per

year,

each

typically

extending

for

two

days,

and

additional

in-person

and

telephonic

meetings

throughout

the

year,

as

needed.

While

the

Board

also

has

a

fifth

one-day

meeting

to

consider

specific

information

surrounding

the

renewal

of

the

Agreement,

the

Board’s

consideration

entails

a

year-long

deliberative

process

whereby

the

Board

and

its

committees

assess

BlackRock’s

services

to

the

Fund.

In

particular,

the

Board

assessed,

among

other

things,

the

nature,

extent

and

quality

of

the

services

provided

to

the

Fund

by

BlackRock,

BlackRock’s

personnel

and

affiliates,

including

(as

applicable):

investment

management

services;

accounting

oversight;

administrative

and

shareholder

services;

oversight

of

the

Fund’s

service

providers;

risk

management

and

oversight;

and

legal,

regulatory

and

compliance

services.

Throughout

the

year,

including

during

the

contract

renewal

process,

the

Independent

Board

Members

were

advised

by

independent

legal

counsel,

and

met

with

independent

legal

counsel

in

various

executive

sessions

outside

of

the

presence

of

BlackRock’s

management.

During

the

year,

the

Board,

acting

directly

and

through

its

committees,

considers

information

that

is

relevant

to

its

annual

consideration

of

the

renewal

of

the

Agreement,

including

the

services

and

support

provided

by

BlackRock

to

the

Fund

and

its

shareholders.

BlackRock

also

furnished

additional

information

to

the

Board

in

response

to

specific

questions

from

the

Board.

This

additional

information

is

discussed

further

in

the

section

titled

“Board

Approving

the

Agreement.”

and

meeting

regulatory

requirements;

procedures;

(f)

and

(i)

various

additional

and

the

At

the

April

Meeting,

the

Board

reviewed

materials

relating

to

its

consideration

of

the

Agreement.

As

a

result

of

the

discussions

that

occurred

during

the

April

Meeting,

and

as

a

culmination

of

the

Board’s

year-long

deliberative

process,

the

Board

presented

BlackRock

with

questions

and

requests

for

additional

information.

BlackRock

responded

to

these

questions

and

requests

with

additional

written

information

in

advance

of

the

May

Meeting.

At

the

May

Meeting,

the

Board

concluded

its

assessment

of,

among

other

things:

(a) the

nature,

extent

and

quality

of

the

provided

by

(f)

any

benefits

to

BlackRock

and

its

as

a

result

of

BlackRock’s

relationship

with

the

Fund;

and

(g) other

factors

deemed

relevant

by

the

Board

Members.

The

Board

also

considered

other

matters

it

deemed

important

to

the

approval

process,

such

as

other

payments

made

to

BlackRock

or

its

affiliates

relating

to

securities

lending

and

cash

management,

and

BlackRock’s

services

related

to

the

valuation

and

pricing

of

Fund

portfolio

holdings.

The

Board

noted

the

willingness

of

BlackRock’s

personnel

to

engage

in

open,

candid

discussions

with

the

Board.

The

Board

did

not

identify

any

particular

information

as

determinative,

and

each

Board

Member

may

have

attributed

different

weights

to

the

various

items

considered.

A.

Nature,

Extent

and

Quality

of

the

Services

Provided

by

BlackRock:

The

Board,

including

the

Independent

Board

Members,

reviewed

the

nature,

extent

and

quality

of

services

provided

by

BlackRock,

including

the

investment

advisory

services,

and

the

resulting

performance

of

the

Fund.

Throughout

the

year,

the

Board

compared

Fund

performance

to

the

performance

of

a

comparable

group

of

mutual

funds,

relevant

benchmark,

and

performance

metrics,

as

applicable.

The

Board

met

with

BlackRock’s

senior

management

personnel

responsible

for

investment

activities,

including

the

senior

investment

officers.

The

Board

also

reviewed

the

materials

provided

by

the

Fund’s

portfolio

management

team

discussing

the

Fund’s

performance,

investment

strategies

and

outlook.

The

Board

considered,

among

other

factors,

with

respect

to

BlackRock:

the

number,

education

and

experience

of

investment

personnel

generally

and

the

Fund’s

portfolio

management

team;

research

capabilities;

investments

by

portfolio

managers

in

the

funds

they

manage;

portfolio

trading

capabilities;

use

of

technology;

commitment

to

compliance;

credit

analysis

capabilities;

risk

analysis

and

oversight

capabilities;

and

the

approach

to

training

and

retaining

portfolio

managers

and

other

research,

advisory

and

management

personnel.

The

Board

also

considered

BlackRock’s

overall

risk

management

program,

including

the

continued

efforts

of

BlackRock

and

its

affiliates

to

address

cybersecurity

risks

and

the

role

of

BlackRock’s

Risk

&

Quantitative

Analysis

Group.

The

Board

engaged

in

a

review

of

BlackRock’s

compensation

structure

with

respect

to

the

Fund’s

portfolio

management

team

and

BlackRock’s

ability

to

attract

and

retain

high-quality

talent

and

create

performance

incentives.

In

addition

to

investment

advisory

services,

the

Board

considered

the

nature

and

quality

of

the

administrative

and

other

non-investment

advisory

services

provided

to

the

Fund.

BlackRock

and

its

affiliates

provide

the

Fund

with

certain

administrative,

shareholder

and

other

services

(in

addition

to

any

such

services

provided

to

the

Fund

by

third

parties)

and

officers

and

other

personnel

as

are

necessary

for

the

operations

of

the

Fund.

In

particular,

BlackRock

and

its

affiliates

provide

the

Fund

with

administrative

services

including,

among

others:

(i)

responsibility

for

disclosure

documents,

such

as

the

prospectus,

the

summary

prospectus

(as

applicable),

the

statement

of

additional

information

and

periodic

shareholder

reports;

(ii)

oversight

of

daily

accounting

and

pricing;

(iii)

responsibility

for

periodic

filings

with

regulators;

(iv)

overseeing

and

coordinating

the

activities

of

third-party

service

providers,

including,

among

others,

the

Fund’s

custodian,

fund

accountant,

transfer

agent,

and

auditor;

(v)

organizing

Board

meetings

and

preparing

the

materials

for

such

Board

meetings;

(vi)

providing

legal

and

compliance

support;

(vii)

furnishing

analytical

and

other

support

to

assist

the

Board

in

its

consideration

of

strategic

issues

such

as

the

merger,

consolidation

or

repurposing

of

certain

open-end

funds;

and

(viii)

performing

or

managing

administrative

functions

necessary

for

the

operation

of

the

Fund,

such

as

tax

reporting,

expense

management,

fulfilling

regulatory

filing

requirements,

overseeing

the

Fund’s

distribution

partners,

and

shareholder

call

center

and

other

services.

The

Board

reviewed

the

structure

and

duties

of

BlackRock’s

fund

administration,

shareholder

services,

and

legal

&

compliance

departments

and

considered

BlackRock’s

policies

and

procedures

for

assuring

compliance

with

applicable

laws

and

regulations.

B.

The

Investment

Performance

of

the

Fund

and

BlackRock

:

The

Board,

including

the

Independent

Board

Members,

also

reviewed

and

considered

the

performance

history

of

the

Fund.

In

preparation

for

the

April

Meeting,

the

Board

was

provided

with

reports

independently

prepared

by

Broadridge,

which

included

an

analysis

of

the

Fund’s

performance

as

of

December

31,

2019,

as

compared

to

its

Performance

Peers.

Broadridge

ranks

funds

in

quartiles,

ranging

from

first

to

fourth,

where

first

is

the

most

desirable

quartile

position

and

fourth

is

the

least

desirable.

In

connection

with

its

review,

the

Board

received

and

reviewed

information

regarding

the

investment

performance

of

the

Fund

as

compared

to

its

Performance

Peers

and

a

weighted

average

benchmark

of

similar

funds,

as

defined

by

BlackRock

(“Benchmark

Weighted

Average”).

The

Board

and

its

Performance

Oversight

Committee

regularly

review,

and

meet

with

Fund

management

to

discuss,

the

performance

of

the

Fund

throughout

the

year.

In

evaluating

performance,

the

Board

focused

particular

attention

on

funds

with

less

favorable

performance

records.

The

Board

also

noted

that

while

it

found

the

data

provided

by

Broadridge

generally

useful,

it

recognized

the

limitations

of

such

data,

including

in

particular,

that

notable

differences

may

exist

between

a

fund

and

its

Performance

Peers

(for

example,

the

investment

objectives

and

strategies).

Further,

the

Board

recognized

that

the

performance

data

reflects

a

snapshot

of

a

period

as

of

a

particular

date

and

that

selecting

a

different

performance

period

could

produce

significantly

different

results.

The

Board

also

acknowledged

that

long-term

performance

could

be

impacted

by

even

one

period

of

significant

outperformance

or

underperformance,

and

that

a

single

investment

theme

could

have

the

ability

to

disproportionately

affect

long-term

performance.

The

Board

noted

that

for

each

of

the

one-

and

three-year

periods

reported,

the

Fund

underperformed

its

Benchmark

Weighted

Average.

The

Board

noted

that

BlackRock

believes

that

the

Benchmark

Weighted

Average

is

an

appropriate

performance

metric

for

the

Fund,

and

that

BlackRock

has

explained

its

rationale

for

this

belief

to

the

Board.

The

Board

and

BlackRock

reviewed

the

Fund’s

underperformance

relative

to

its

Benchmark

Weighted

Average

during

the

applicable

periods.

The

Board

noted

that

effective

May

11,

2020,

the

Fund

had

undergone

a

change

in

its

investment

objective

and

investment

strategy,

and

in

that

connection

had

changed

its

name

from

BlackRock

Money

Market

Portfolio

to

BlackRock

Wealth

Liquid

Environmentally

Aware

Fund.

C.

Consideration

of

the

Advisory/Management

Fees

and

the

Estimated

Cost

of

the

Services

and

Estimated

Profits

Realized

by

BlackRock

and

its

Affiliates

from

their

Relationship

with

the

Fund:

The

Board,

including

the

Independent

Board

Members,

reviewed

the

Fund’s

contractual

management

fee

rate

compared

with

those

of

its

Expense

Peers.

The

contractual

management

fee

rate

represents

a

combination

of

the

advisory

fee

and

any

administrative

fees,

before

taking

into

account

any

reimbursements

or

fee

waivers.

The

Board

also

compared

the

Fund’s

total

expense

ratio,

as

well

as

its

actual

management

fee

rate,

to

those

of

its

Expense

Peers.

The

total

expense

ratio

represents

a

fund’s

total

net

operating

expenses,

including

any

12b-1

or

non-12b-1

service

fees.

The

total

expense

ratio

gives

effect

to

any

expense

reimbursements

or

fee

waivers,

and

the

actual

management

fee

rate

gives

effect

to

any

management

fee

reimbursements

or

waivers.

The

Board

considered

the

services

provided

and

the

fees

charged

by

BlackRock

and

its

affiliates

to

other

types

of

clients

with

similar

investment

mandates,

as

applicable,

including

institutional

accounts

and

sub-advised

mutual

funds

(including

mutual

funds

sponsored

by

third

parties).

The

Board

received

and

reviewed

statements

relating

to

BlackRock’s

financial

condition.

The

Board

reviewed

BlackRock’s

profitability

methodology

and

was

also

provided

with

an

estimated

profitability

analysis

that

detailed

the

revenues

earned

and

the

expenses

incurred

by

BlackRock

for

services

provided

to

the

Fund.

The

Board

reviewed

BlackRock’s

estimated

profitability

with

respect

to

the

Fund

and

other

funds

the

Board

currently

oversees

for

the

year

ended

December

31,

2019

compared

to

available

aggregate

estimated

profitability

data

provided

for

the

prior

two

years.

The

Board

reviewed

BlackRock’s

estimated

profitability

with

respect

to

certain

other

U.S.

fund

complexes

managed

by

BlackRock

and/or

its

affiliates.

The

Board

reviewed

BlackRock’s

assumptions

and

methodology

of

allocating

expenses

in

the

estimated

profitability

analysis,

noting

the

inherent

limitations

in

allocating

costs

among

various

advisory

products.

The

Board

recognized

that

profitability

may

be

affected

by

numerous

factors

including,

among

other

things,

fee

waivers

and

expense

reimbursements

by

BlackRock,

the

types

of

funds

managed,

precision

of

expense

allocations

and

business

mix.

The

Board

thus

recognized

that

calculating

and

comparing

profitability

at

the

individual

fund

level

is

difficult.

The

Board

noted

that,

in

general,

individual

fund

or

product

line

profitability

of

other

advisors

is

not

publicly

available.

The

Board

reviewed

BlackRock’s

overall

operating

margin,

in

general,

compared

to

that

of

certain

other

publicly

traded

asset

management

firms.

The

Board

considered

the

differences

between

BlackRock

and

these

other

firms,

including

the

contribution

of

technology

at

BlackRock,

BlackRock’s

expense

management,

and

the

relative

product

mix.

The

Board

considered

whether

BlackRock

has

the

financial

resources

necessary

to

attract

and

retain

high

quality

investment

management

personnel

to

perform

its

obligations

under

the

Agreement

and

to

continue

to

provide

the

high

quality

of

services

that

is

expected

by

the

Board.

The

Board

further

considered

factors

including

but

not

limited

to

BlackRock’s

commitment

of

time,

assumption

of

risk,

and

liability

profile

in

servicing

the

Fund,

including

in

contrast

to

what

is

required

of

BlackRock

with

respect

to

other

products

with

similar

investment

mandates

across

the

open-end

fund,

ETF,

closed-end

fund,

sub-advised

mutual

fund,

separately

managed

account,

collective

investment

trust,

and

institutional

separate

account

product

channels,

as

applicable.

The

Board

noted

that

the

Fund’s

contractual

management

fee

rate

ranked

in

the

fourth

quartile,

and

that

the

actual

management

fee

rate

and

total

expense

ratio

each

ranked

in

the

first

quartile

relative

to

the

Fund’s

Expense

Peers.

The

Board

further

noted

that

the

Fund

has

an

advisory

fee

arrangement

that

includes

breakpoints

that

adjust

the

fee

rate

downward

as

the

size

of

the

Fund

increases

above

certain

contractually

specified

levels.

The

Board

noted

that

if

the

size

of

the

Fund

were

to

decrease,

the

Fund

could

lose

the

benefit

of

one

or

more

breakpoints.

The

Board

additionally

noted

that

BlackRock

and

the

Board

have

contractually

agreed

to

a

cap

on

the

Fund’s

total

expenses

as

a

percentage

of

the

Fund’s

average

daily

net

assets

on

a

class-by-class

basis.

D.

Economies

of

Scale:

The

Board,

including

the

Independent

Board

Members,

considered

the

extent

to

which

economies

of

scale

might

be

realized

as

the

assets

of

the

Fund

increase,

including

the

existence

of

fee

waivers

and/or

expense

caps,

as

applicable,

noting

that

any

contractual

fee

waivers

and

contractual

expense

caps

had

been

approved

by

the

Board.

In

its

consideration,

the

Board

further

considered

the

continuation

and/or

implementation

of

fee

waivers

and/or

expense

caps,

as

applicable.

The

Board

also

considered

the

extent

to

which

the

Fund

benefits

from

such

economies

of

scale

in

a

variety

of

ways

and

whether

there

should

be

changes

in

the

advisory

fee

rate

or

breakpoint

structure

in

order

to

enable

the

Fund

to

more

fully

participate

in

these

economies

of

scale.

The

Board

considered

the

Fund’s

asset

levels

and

whether

the

current

fee

schedule

was

appropriate.

E.

Other

Factors

Deemed

Relevant

by

the

Board

Members:

The

Board,

including

the

Independent

Board

Members,

also

took

into

account

other

ancillary

or

“fall-out”

benefits

that

BlackRock

or

its

affiliates

may

derive

from

BlackRock’s

respective

relationships

with

the

Fund,

both

tangible

and

intangible,

such

as

BlackRock’s

ability

to

leverage

its

investment

professionals

who

manage

other

portfolios

and

its

risk

management

personnel,

an

increase

in

BlackRock’s

profile

in

the

investment

advisory

community,

and

the

engagement

of

BlackRock’s

affiliates

as

service

providers

to

the

Fund,

including

for

administrative,

distribution,

securities

lending

and

cash

management

services.

The

Board

also

considered

BlackRock’s

overall

operations

and

its

efforts

to

expand

the

scale

of,

and

improve

the

quality

of,

its

operations.

The

Board

also

noted

that,

subject

to

applicable

law,

BlackRock

may

use

and

benefit

from

third-party

research

obtained

by

soft

dollars

generated

by

certain

registered

fund

transactions

to

assist

in

managing

all

or

a

number

of

its

other

client

accounts.

In

connection

with

its

consideration

of

the

Agreement,

the

Board

also

received

information

regarding

BlackRock’s

brokerage

and

soft

dollar

practices.

The

Board

received

reports

from

BlackRock

which

included

information

on

brokerage

commissions

and

trade

execution

practices

throughout

the

year.

The

Board

noted

the

competitive

nature

of

the

open-end

fund

marketplace,

and

that

shareholders

are

able

to

redeem

their

Fund

shares

if

they

believe

that

the

Fund’s

fees

and

expenses

are

too

high

or

if

they

are

dissatisfied

with

the

performance

of

the

Fund.

Conclusion

The

Board,

including

the

Independent

Board

Members,

unanimously

approved

the

continuation

of

the

Agreement

between

the

Manager

and

the

Trust,

on

behalf

of

the

Fund,

for

a

one-year

term

ending

June

30,

2021.

Based

upon

its

evaluation

of

all

of

the

aforementioned

factors

in

their

totality,

as

well

as

other

information,

the

Board,

including

the

Independent

Board

Members,

was

satisfied

that

the

terms

of

the

Agreement

were

fair

and

reasonable

and

in

the

best

interest

of

the

Fund

and

its

shareholders.

In

arriving

at

its

decision

to

approve

the

Agreement,

the

Board

did

not

identify

any

single

factor

or

group

of

factors

as

all-important

or

controlling,

but

considered

all

factors

together,

and

different

Board

Members

may

have

attributed

different

weights

to

the

various

factors

considered.

The

Independent

Board

Members

were

also

assisted

by

the

advice

of

independent

legal

counsel

in

making

this

determination.

Householding

The

Fund

will

mail

only

one

copy

of

shareholder

documents,

including

prospectuses,

annual

and

semi-annual

reports

and

proxy

statements,

to

shareholders

with

multiple

practice

is

commonly

called

“householding”

duplicate

mailings

of

shareholder

documents.

of

your

shareholder

documents

may

be

householded

indefinitely

unless

you

instruct

us

otherwise.

If

you

do

not

want

the

mailing

of

these

documents

to

be

combined

with

those

for

other

members

of

your

household,

Agent at
