have

For

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

summarizes

the
