required

by

for

complete

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

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

value

of

the

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.

(9)

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.

(10)

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.

(11)

The

rate

shown

is

the

one-day

yield

as

of

the

end

of

the

reporting

period.

(12)

Other

assets

less

liabilities

includes

the

unrealized

appreciation

(depreciation)

of

certain

over-the-counter

("OTC")

derivatives

as

well

as

the

for

Certain

normally

GAAP

have

been

condensed

or

from

this

pursuant

to

For

a

full

set

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
