report.
Fair
Value
Measurements
The
Fund’s
investments
in
securities
are
recorded
at
their
estimated
fair
value
utilizing
valuation
methods
approved
by
the
Board
of
Directors/
Trustees.
Fair
value
is
defined
as
the
price
that
would
be
received
upon
selling
an
investment
or
transferring
a
liability
in
an
orderly
transaction
to
an
independent
buyer
in
the
principal
or
most
advantageous
market
for
the
investment.
U.S.
GAAP
establishes
the
three-tier
hierarchy
which
is
used
to
maximize
the
use
of
observable
market
data
and
minimize
the
use
of
unobservable
inputs
and
to
establish
classification
of
fair
value
measurements
for
disclosure
purposes.
Observable
inputs
reflect
the
assumptions
market
participants
would
use
in
pricing
the
asset
or
liability.
Observable
inputs
are
based
on
market
data
obtained
from
sources
independent
of
the
reporting
entity.
Unobservable
inputs
reflect
management’s
assumptions
about
the
assumptions
market
participants
would
use
in
pricing
the
asset
or
liability.
Unobservable
inputs
are
based
on
the
best
information
available
in
the
circumstances.
The
following
is
a
summary
of
the
three-tiered
hierarchy
of
valuation
input
levels.
Level
1
–
Inputs
are
unadjusted
and
prices
are
determined
using
quoted
prices
in
active
markets
for
identical
securities.
Level
2
–
Prices
are
determined
using
other
significant
observable
inputs
(including
quoted
prices
for
similar
securities,
interest
rates,
credit
spreads,
etc.).
Level
3
–
Prices
are
determined
using
significant
unobservable
inputs
(including
management’s
assumptions
in
determining
the
fair
value
of
investments).
The
following
table
summarizes
the
market
value
of
the
Fund's
investments
as
of
the
end
of
the
reporting
period,
based
on
the
inputs
used
to
value
them:

Various
funds
and
accounts
managed
by
Nuveen,
including
the
Fund,
collectively
are
a
substantial
minority
holder
of
ENGH’s
outstanding
shares
of
common
stock,
and
possess
certain
other
rights
with
respect
to
the
corporate
governance
of
ENGH.
Due
to
these
facts,
under
the
federal
securities
laws,
the
securities
of
ENGH
held
by
Nuveen
funds
and
accounts,
including
the
Fund,
cannot
be
sold
except
under
limited
conditions
(which
are
not  currently
satisfied).
The
Fund
is
therefore
unable
to
sell
such
shares
in
ordinary
secondary
market
transactions
at
this
time.
On

2023
Vistra
Corp.
(“Vistra”)
announced
that
it
has
executed
a
definitive
agreement
with
Energy
Harbor
Corp.,
pursuant
to
which
Energy
Harbor
will
merge
with
and
into
a
newly-
formed
subsidiary
of
Vistra.  The
companies
anticipate
closing
the
transaction
in
the
second
half
of
2023.  In
connection
with
the
transaction,
Nuveen
funds
and
accounts
expect
to
receive
a
combination
of
cash
and
shares
in
a
newly
formed
entity.
Nuveen
expects
these
shares
to
be
issued
in
a
private
transaction
and
may
have
reduced
secondary
market
liquidity.  The
transaction
is
subject
to
certain
regulatory
approvals
and
there
can
be
no
assurance
that
the
transaction
will
close.
