Fair

Value

Hierarchy

as

of

Period

End

Various

inputs

are

used

in

determining

the

fair

value

of

financial

instruments

at

the

measurement

date.

These

inputs

to

valuation

techniques

are

categorized

into

a

fair

value

hierarchy

consisting

of

three

broad

levels

for

financial

reporting

purposes

as

follows:

Level

1

—

Unadjusted

price

quotations

in

active

markets/exchanges

that

the

Fund

has

the

ability

to

access

for

identical

assets

or

liabilities;

Level

2

—

Inputs

other

than

quoted

prices

included

within

Level

1

that

are

observable

for

the

asset

or

liability,

either

directly

or

indirectly;

and

Level

3

—

Inputs

that

are

unobservable

and

significant

to

the

entire

fair

value

measurement

for

the

asset

or

liability

(including

the

Valuation

Committee's

assumptions

used

in

determining

the

fair

value

of

financial

instruments).

The

hierarchy

gives

the

highest

priority

to

unadjusted

quoted

prices

in
