required

for

Certain

normally
included
in
financial
statements
prepared
in
accordance
with
U.S.
GAAP
have
been
condensed
or
omitted
from
this
report
pursuant
to
the
rules
of
the
SEC.
For

full
set

Fund’s
most

filed
annual

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

determining

hierarchy.
Transfers
in

out
of

are
generally
due
to
the

to
the

extent
the

determines
that
the
valuation
inputs
or

of
the

On
March
1,
2024,
Vistra
Corp.
(“Vistra”)
completed
its
acquisition
of
Energy
Harbor
Corp
(“ENGH”). ENGH
has
been
merged
into
a
newly
formed
subsidiary
of
Vistra,
Vistra
Vision. In
connection
with
the
transaction,
holders
of
ENGH
common
stock
received
a
combination
of
cash
and
membership
interests
in
Vistra
Vision.
These
Vistra
Vision
interests
were
issued
in
a
private
transaction
and
may
have
reduced
secondary
market
liquidity. On
September
18,
2024,
Vistra
and
Nuveen
agreed
to
terms
for
the
sale
of
the
Vistra
Vision
interest.
In
exchange
for
its
membership
interest
in
Vistra
Vision,
Nuveen
will
receive
a
series
of
cash
payments
from
Vistra
over
a
two-year
period
from
December
2024
through
December
2026.
(l)
Senior
loans
generally
pay
interest
at
rates
which
are
periodically
adjusted
by
reference
to
a
base
short-term,
floating
lending
rate
(Reference
Rate)
plus
an
assigned
fixed
rate
(Spread).
These
floating
lending
rates
are
generally
(i)
the
lending
rate
referenced
by
the
Secured
Overnight
Financing
Rate
(“SOFR”),
or
(ii)
the
prime
rate
offered
by
one
or
more
major
United
States
banks.
Senior
loans
may
be
considered
restricted
in
that
the
Fund
ordinarily
is
contractually
obligated
to
receive
approval
from
the
agent
bank
and/or
borrower
prior
to
the
disposition
of
a
senior
loan.
The
rate
shown
is
the
coupon
as
of
the
end
of
the
reporting
period.
(m)
Senior
loans
generally
are
subject
to
mandatory
and/or
optional
prepayment.
Because
of
these
mandatory
prepayment
conditions
and
because
there
may
be
significant
economic
incentives
for
a
borrower
to
prepay,
prepayments
of
senior
loans
may
occur.
As
a
result,
the
actual
remaining
maturity
of
senior
loans
held
may
be
substantially
less
than
the
stated
maturities
shown.
