required

for

Certain

disclosures
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
a
full
set
of
the

notes

statements,
please
refer
to
the
Fund’s
most
recently
filed
annual
or
semi-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
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

them:

For
Fund
portfolio
compliance
purposes,
the
Fund’s
industry
classifications
refer
to
any
one
or
more
of
the
industry
sub-classifications
used
by
one
or
more
widely
recognized
market
indexes
or
ratings
group
indexes,
and/or
as
defined
by
Fund
management.
This
definition
may
not
apply
for
purposes
of
this
report,
which
may
combine
industry
sub-classifications
into
sectors
for
reporting
ease.
(1)
All
percentages
shown
in
the
Portfolio
of
Investments
are
based
on
net
assets.
(2)
For
financial
reporting
purposes,
the
ratings
disclosed
are
the
highest
of
Standard
&
Poor’s
Group
(“Standard
&
Poor’s”),
Moody’s
Investors
Service,
Inc.
(“Moody’s”)
or
Fitch,
Inc.
(“Fitch”)
rating.
This
treatment
of
split-rated
securities
may
differ
from
that
used
for
other
purposes,
such
as
for
Fund
investment
policies.
Ratings
below
BBB
by
Standard
&
Poor’s,
Baa
by
Moody’s
or
BBB
by
Fitch
are
considered
to
be
below
investment
grade.
Holdings
designated

are
not

by
any
of
these
national
rating
agencies.
(3)
Investment,
or
a
portion
of
investment,
is
out
on
loan
for
securities
lending.
The
total
value
of
the
securities
out
on
loan
as
of
the
end
of
the
reporting
period
was
$3,123,287.
(4)
Variable
rate
security.
The
rate
shown
is
the
coupon
as
of
the
end
of
the
reporting
period.
(5)
Defaulted
security.
A
security
whose
issuer
has
failed
to
fully
pay
principal
and/or
interest
when
due,
or
is
under
the
protection
of
bankruptcy.
(6)
For
fair
value
measurement
disclosure
purposes,
investment
classified
as
Level
3.
(7)
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
London
Inter-Bank
Offered
Rate
("LIBOR"),
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.
(8)
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.
(9)
Perpetual
security.
Maturity
date
is
not
applicable.
(10)
Contingent
Capital
Securities
(“CoCos”)
are
hybrid
securities
with
loss
absorption
characteristics
built
into
the
terms
of
the
security
for
the
benefit
of
the
issuer.
For
example,
the
terms
may
specify
an
automatic
write-down
of
principal
or
a
mandatory
conversion
into
the
issuer’s
common
stock
under
certain
adverse
circumstances,
such
as
the
issuer’s
capital
ratio
falling
below
a
specified
level.
(11)
Non-income
producing;
issuer
has
not
declared
an
ex-dividend
date
within
the
past
twelve
months.
(12)
The
Fund
may
loan
securities
representing
up
to
one
third
of
the
market
value
of
its
total
assets
(which
includes
collateral
for
securities

principles
(“U.S.
GAAP”)
and

conformity
with
the
applicable
rules

regulations
of
the
U.S.
Securities
and
Exchange
Commission
(“SEC”)
related
to
interim
filings.

does
not
include
all
information
and
footnotes
required
by
U.S.
GAAP
for
complete
financial
statements.
Certain
footnote
disclosures
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
a
full
set
of
the
Fund’s
notes
to
financial
statements,
please
refer
to
the
Fund’s
most
recently
filed
annual
or
semi-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
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

them:

For
Fund
portfolio
compliance
purposes,
the
Fund’s
industry
classifications
refer
to
any
one
or
more
of
the
industry
sub-classifications
used
by
one
or
more
widely
recognized
market
indexes
or
ratings
group
indexes,
and/or
as
defined
by
Fund
management.
This
definition
may
not
apply
for
purposes
of
this
report,
which
may
combine
industry
sub-classifications
into
sectors
for
reporting
ease.

All

shown
in
the

are
based
on

For
financial
reporting
purposes,
the
ratings
disclosed
are
the
highest
of
Standard

Poor’s
Group
(“Standard

Poor’s”),
Moody’s
Investors
Service,
Inc.
(“Moody’s”)
or
Fitch,

(“Fitch”)
rating.
This
treatment
of
split-rated
securities
may
differ
from
that
used
for
other
purposes,
such
as
for
Fund
investment
policies.
Ratings
below
BBB
by
Standard

Poor’s,
Baa
by
Moody’s
or
BBB
by
Fitch
are
considered
to
be
below
investment

A

and/or
interest
when

or
is
under
the

of
bankruptcy.

(9)
Contingent
Capital
Securities
(“CoCos”)
are
hybrid
securities
with
loss
absorption
characteristics
built
into
the
terms
of
the
security
for
the
benefit
of
the
issuer.
For
example,
the
terms
may
specify
an
automatic
write-down
of
principal
or
a
mandatory
conversion
into
the
issuer’s
common
stock
under
certain
adverse
circumstances,
such
as
the
issuer’s
capital
ratio
falling
below
a
specified
level.
(10)
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
London
Inter-Bank
Offered
Rate
("LIBOR"),
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.
(11)
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.
(12)
The
Fund
may
loan
securities
representing
up
to
one
third
of
the
market
value
of
its
total
assets
(which
includes
collateral
for
securities
on
loan)
to
broker
dealers,
banks,
and
other
institutions.
The
collateral
maintained
by
the
Fund
shall
have
a
market
value,
at
the
inception
of
each
loan,
equal
to
not
less
than
100%
of
the
market
value
of
the
loaned
securities.
The
cash
collateral
received
by
the
Fund
is
invested
in
this
money
market
fund.
(13)
The
rate
shown
is
the
one-day
yield
as
of
the
end
of
the
reporting
period.
(14)
Other
assets
less
liabilities
includes
the
unrealized
appreciation
(depreciation)
of
certain
over-the-counter
("OTC")
derivatives
as
well
as
the
OTC
cleared
and
exchange-traded
derivatives,
when
applicable.

Certain
details
associated
with
this

are
not

prior

senior

typically
trade
without

and
therefore
a
