Dear
Shareholder,
The
combination
of
continued
economic
growth
and
cooling
inflation
provided
a
supportive
backdrop
for
investors
during
the
12-month
reporting
period
ended
March
31,
2024.
Higher
interest
rates
helped
to
rein
in
inflation,
and
the
Consumer
Price
Index
decelerated
substantially
while
remaining
above
pre-pandemic
levels.
A
moderating
labor
market
helped
ease
inflationary
pressure,
although
wages
continued
to
grow.
Wage
and
job
growth
powered
robust
consumer
spending,
backstopping
the
economy.
On
October
7,
2023,
Hamas
launched
a
horrific
attack
on
Israel.
The
ensuing
war
has
had
a
significant
humanitarian
impact
and
could
lead
to
heightened
economic
and
market
volatility.
We
see
geopolitics
as
a
structural
market
risk
going
forward.
See
our
geopolitical
risk
dashboard
at
blackrock.com
for
more
details.
Equity
returns
were
robust
during
the
period,
as
interest
rates
stabilized
and
the
economy
proved
to
be
more
resilient
than
many
investors
expected.
The
U.S.
economy
continued
to
show
strength,
and
growth
further
accelerated
in
the
second
half
of
2023.
Large-capitalization
U.S.
stocks
posted
particularly
substantial
gains,
supported
by
the
performance
of
a
few
notable
technology
companies,
while
small-capitalization
U.S.
stocks’
advance
was
slower
but
still
robust.
Meanwhile,
international
developed
market
equities
also
gained
strongly,
while
emerging
market
stocks
advanced
at
a
more
modest
pace.
The
10-year
U.S.
Treasury
yield
rose
during
the
reporting
period,
as
investors
reacted
to
elevated
inflation
and
attempted
to
anticipate
future
interest
rate
changes.
However,
higher
yields
drove
positive
returns
overall
for
10-
year
U.S.
Treasuries
and
solid
gains
in
shorter-duration
U.S.
Treasuries.
The
corporate
bond
market
benefited
from
improving
economic
sentiment,
although
high-yield
corporate
bond
prices
fared
significantly
better
than
investment-grade
bonds
as
demand
from
yield-seeking
investors
remained
strong.
The
U.S.
Federal
Reserve
(the
“Fed”),
attempting
to
manage
persistent
inflation,
raised
interest
rates
twice
during
the
12-month
period,
but
paused
its
tightening
after
its
July
meeting.
The
Fed
also
continued
to
reduce
its
balance
sheet
by
not
replacing
some
of
the
securities
that
reach
maturity.
Supply
constraints
appear
to
have
become
an
embedded
feature
of
the
new
macroeconomic
environment,
making
it
difficult
for
developed
economies
to
increase
production
without
sparking
higher
inflation.
Geopolitical
fragmentation
and
an
aging
population
risk
further
exacerbating
these
constraints,
keeping
the
labor
market
tight
and
wage
growth
high.
Although
the
Fed
has
stopped
tightening
for
now,
we
believe
that
the
new
economic
regime
means
that
the
Fed
will
need
to
maintain
high
rates
for
an
extended
period
despite
the
market’s
hopes
for
rapid
interest
rate
cuts,
as
reflected
in
the
ongoing
rally.
In
this
new
regime,
we
anticipate
greater
volatility
and
dispersion
of
returns,
creating
more
opportunities
for
selective
portfolio
management.
Looking
at
developed
market
stocks,
we
have
an
overweight
stance
on
U.S.
stocks
overall,
particularly
given
the
promise
of
emerging
AI
technologies.
We
are
also
overweight
Japanese
stocks
as
shareholder-friendly
policies
generate
increased
investor
interest,
although
we
maintain
an
underweight
stance
on
European
stocks.
In
credit,
there
are
selective
opportunities
in
the
near
term
despite
tighter
credit
and
financial
conditions.
For
fixed
income
investing
with
a
six-
to
twelve-month
horizon,
we
see
the
most
attractive
investments
in
short-term
U.S.
Treasuries
and
hard-currency
emerging
market
bonds.
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
to

your
financial
advisor

For

Period
Ended

2024
BlackRock
Annual
Report
to
Shareholders
4
During
the
12-month
period
ended
March
31,
2024,
economic
conditions
in
the
United
States
remained
robust
throughout
most
of
the
reporting
period.
The
unemployment
rate
trended
at
low
levels
throughout,
although
edged
up
to
3.8%
in
March
2024.
The
consumer
price
index
(“CPI”)
hit
3.09%
in
January
2023
(the
lowest
rate
since
March
2021)
but
showed
signs
of
potential
reflation,
rising
to
3.2%
by
the
end
of
the
quarter.
The
Federal
Open
Market
Committee
(the
“FOMC”
or
the
“Committee”),
increased
the
range
of
the
federal
funds
target
rate
to
5.25%-5.50%
in
July
2023
and
has
since
left
the
rate
unchanged
to
assess
the
impact
of
policy
firming
on
inflation
and
employment.
The
median
federal
funds
rate
forecast
contained
in
the
Summary
of
Economic
Projections
(“SEP”)
released
in
conjunction
with
the
FOMC
meeting
for
2024
was
unchanged
from
the
December
2023
projection
of
4.60%
and
continued
to
imply,
in
our
estimation,
three
cuts
of
0.25%
in
the
range
for
the
target
rate
for
2024.
The
FOMC
again
noted
it
will
continue
reducing
its
holdings
of
Treasury
securities,
agency
debt
and
agency
mortgage-backed
securities
as
delineated
in
its
Plans
for
Reducing
the
Size
of
the
Federal
Reserve’s
Balance
Sheet
released
in
conjunction
with
the
May
4,
2022,
FOMC
meeting.
In
a
statement
released
in
conjunction
with
the
meeting,
the
Committee
reiterated
that
inflation
“remains
elevated”
while
again
acknowledging
that
it
has
“eased
over
the
past
year.”
The
statement
also
continued
to
recognize
the
“solid
pace”
of
economic
growth.
The
Committee
also
echoed
its
previous
outlook
for
future
interest
rate
actions,
noting
“any
adjustments”
to
the
federal
funds
target
range
would
be
based
on
an
evaluation
of
“incoming
data,
the
evolving
outlook,
and
the
balance
of
risks,”
while
again
acknowledging
that
the
FOMC
“does
not
expect
it
will
be
appropriate
to
reduce
the
target
range
until
it
has
gained
greater
confidence
that
inflation
is
moving
sustainably
toward”
its
2%
target.
Utilization
of
the
Federal
Reserve’s
Reverse
Repo
program
(“RRP”)
decreased
in
2024
as
investors
rotated
out
of
the
RRP
and
into
new
Treasury
supply
and
dealer
repo
rates
remained
more
attractive,
in
our
opinion.
Year
to
date,
balances
held
at
the
RRP
have
fallen
from
$700
billion
to
$594
billion
at
March
month-end.
As
of
March
31,
2024,
Treasury
bill
(“T-bill”)
tenors
between
one-month
and
one-year
traded
between
5.03%
and
5.37%.
For
reference,
T-bills
of
the
same
tenors
traded
between
4.53%
and
4.62%
as
of
March
31,
2023.
Rates
continuously
trended
upward
through
early
2023
and
since
appeared
to
have
leveled
off
with
the
expectation
that
the
Fed
may
have
reached
the
end
of
its
hiking
cycle.
Portfolio
positioning
as
of
March
31,
2024
reflected
our
outlook
that
the
Fed
may
be
considering
holding
interest
rates
higher
for
longer
over
the
coming
months.
The
Fund
has
been
selectively
adding
duration
into
longer-dated
fixed
rate
positions,
resulting
in
a
portfolio
weighted
average
maturity
(“WAM”)
of
42
days.
The
decreased
allocation
to
floating-rate
securities
of
14%
reflects
our
view
that
fixed-rate
investments
may
be
more
attractive
at
this
time.
Portfolio
purchases
over
the
reporting
period
were
primarily
focused
on
U.S.
dollar
denominated
certificate
of
deposits
and
commercial
paper
with
floating
rate
coupons
indexed
to
the
secured
overnight
financing
rate
(“SOFR”)—a
broad
measure
of
the
cost
of
borrowing
cash
overnight
collateralized
by
Treasury
securities—
and
fixed
rate
securities
appropriately
priced
in
line
with
our
expectations
for
the
future
path
of
monetary
policy.
Issuer
and
security
selection
were
consistent
with
the
environmental
focus
of
the
portfolio.

Investment
Objective
BlackRock
Wealth
Liquid
Environmentally
Aware
Fund’s
(the
“Fund”)
investment
objective
is
to
seek
as
high
a
level
of
current

as
is
consistent
with
liquidity
and
preservation
of
capital
while
giving
consideration
to
select

Expense
Example
See
“Disclosure
of
Expenses”
for
further
information
on
how
expenses
were
calculated.
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
(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.

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
using
the
specific
identification
method.
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
Discretionary
Liquidity
Fees:
Any
discretionary
liquidity
fees
imposed
on
the
value
of
shares
redeemed
are
recorded
as
paid-in-capital.
The
discretionary liquidity
fees
are
collected
and
retained
by
the
Fund
for
the
benefit
of the
Fund’s
remaining shareholders. 
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
one
of
its
custodians
whereby
credits
are
earned
on
uninvested
cash
balances.
For
financial
reporting
purposes,
custodian
credit,
if
any,
are
included
in
interest
income
in
the
Statement
of
Operation.

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);
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. 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.
4.
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 a
fund
and
its
counterparties.
Typically,
a
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, a
fund
could
experience
losses,
delays
and
costs
in
liquidating
the
collateral.
Repurchase
agreements
are
entered
into
by a
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
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.

AGREEMENT
AND
OTHER

the
Fund
for
which
BIL
acts
as
sub-adviser,

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
March
31,
2024,
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.
The
tax
character
of
distributions
paid
was
as
follows: 
As
of
March
31,
2024,
the
tax
components
of
accumulated earnings
(loss) were
as
follows:  
(a)
Amounts
available
to
offset
future
realized
capital
gains.
During
the
year
ended March
31,
2024,
the
Fund utilized
the
following
amount
of
its
capital
loss
carryforward:
For
the
fund,
the
cost
for
U.S.
federal
income
tax
purposes
is
the
same
as
book
cost.

 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. 
On
July
12,
2023,
the
SEC
approved
changes
to
money
market
fund
regulations.
These
changes,
among
other
things:
(
i
)
eliminate
provisions
that
permit
a
money
market
fund
to
suspend
redemptions
except
in
liquidations,
(ii)
require
institutional
prime
and
institutional
tax-exempt
money
market
funds
to
impose
mandatory
liquidity
fees
under
certain
conditions,
(iii)
permit
a
discretionary
liquidity
fee
for
a
non-government
money
market
fund
and
(iv)
increase
minimum
daily
and
weekly
liquidity
for
all
money
market
funds.
These
changes
will
be
implemented
over
the
next
12
months
depending
on
the
change
and
may
affect
the
Fund’s
operations
and
return
potential.
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:
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.
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.
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. 
Geographic/Asset
Class
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.
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 period
of
historically
low
interest
rates
that
ended
in
March
2022. The
Federal
Reserve
has
raised
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.

of

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
March
31,
2024,
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.

visually
engaging
streamlined
annual

have
a
compliance
date
of
July
24,

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 Experts – 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:
 
Neil A. Cotty
Henry R. Keizer
Kenneth L. Urish
 
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.

1
The nature of the services includes assurance and related services reasonably related to the performance of the audit or review of financial statements not included in Audit Fees, including accounting consultations, agreed-upon procedure reports, attestation reports, comfort letters, out-of-pocket expenses and internal control reviews not required by regulators.
2
The nature of the services includes tax compliance and/or tax preparation, including services relating to the filing or amendment of federal, state or local income tax returns, regulated investment company qualification reviews, taxable income and tax distribution calculations.
3
Non-audit fees of $2,149,000 and $2,154,000 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.


               (e)(1) Audit Committee Pre-Approval Policies and Procedures:
         
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

Previous Fiscal Year End
BlackRock Wealth Liquid Environmentally Aware Fund

              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
$2,149,000
$2,154,000
 
              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.
               (i) – Not Applicable
               (j) – Not Applicable

Item 6 – Investments

(a) The registrant’s Schedule of Investments is included as part of the Report to Stockholders filed under Item 1(a) of this Form.
