SIGNIFICANT

ACCOUNTING

POLICIES

The

following

is

a

summary

of

significant

accounting

policies

consistently

followed

by

the

Fund:

Net

Asset

Value

The

Net

Asset

Value

(“NAV”)

of

each

class

of

the

Fund

is

determined

by

dividing

the

net

assets

attributable

to

each

class

of

shares

of

the

Fund

by

the

number

of

issued

and

outstanding

shares

of

the

class

of

the

Fund

on

each

business

day

as

of

4

p.m.

ET.

Security

Valuation

Pursuant

to

Rule

2a-5

under

the

1940

Act,

the

Board

of

Trustees

(the

"Board"

or

the

"Board

of

Trustees")

has

designated

the

Adviser

as

the

"valuation

designee"

with

respect

to

the

fair

valuation

of

the

Fund's

portfolio

securities,

subject

to

oversight

by

and

periodic

reporting

to

the

Board. Fixed

income

securities

for

which

market

quotations

are

readily

available were

valued

during

the

period at

prices

as

provided

by

independent

pricing

vendors

or

broker

quotes.

The

Fund

received

pricing

information

from

independent

pricing

vendors

selected

and

overseen

by

the

valuation

designee.

Securities

with

a

demand

feature

exercisable

within

one

to

seven

days

are

valued

at

par.

The

Fund

also

uses

a

benchmark

pricing

system

to

the

extent

vendors’

prices

for

their

securities

are

either

inaccurate

(such

as

when

the

reported

prices

are

different

from

recent

known

market

transactions)

or

are

not

available

from

another

pricing

source.

For

a

security

priced

using

this

system,

the

Adviser

initially

selects

a

proxy

composed

of

a

relevant

security

(e.g.,

U.S.

Treasury

Note)

or

benchmark

(e.g.,

LIBOR)

and

a

multiplier,

divisor

or

margin

that

the

Adviser

believes

would

together

best

reflect

changes

in

the

market

value

of

the

security.

The

value

of

the

security

changes

daily

based

on

changes

to

the

market

price

of

the

assigned

benchmark.

The

benchmark

pricing

system

is

continuously

reviewed

by

the

Adviser

and

implemented

according

to

the

pricing

policy

reviewed

by

the

Board.

S&P

500

Index

futures

contracts

are

valued

at

the

first

sale

price

after

4

p.m.

ET

on

the

Chicago

Mercantile

Exchange.

All

other

futures

contracts

are

valued

at

the

official

settlement

price

of

the

exchange

on

which

those

securities

are

traded.

Equity

securities,

including

depository

receipts,

are

valued

at

the

last

reported

sale

price

or

the

market’s

closing

price

on

the

exchange

or

market

on

which

such

securities

are

traded,

as

of

the

close

of

business

on

the

day

the

securities

are

being

valued

or,

lacking

any

sales,

at

the

average

of

the

bid

and

ask

prices.

In

cases

where

equity

securities

are

traded

on

more

than

one

exchange,

the

securities

are

valued

on

the

exchange

or

market

determined

by

the

Adviser

to

be

the

broadest

and

most

representative

market,

which

may

be

either

a

securities

exchange

or

the

over-the-counter

market.

Equity

options

are

valued

at

the

average

of

the

bid

and

ask

prices.

Securities

and

other

assets

that

could

not be

valued

as

described

above were

valued

for

the

period at

their

fair

value

as

determined

by

the

Adviser

in

accordance

with

procedures

approved by

and

under

the

general

oversight

of

the

Board.

Investments

in

registered

open-ended

investment

companies,

including

those

classified

as

money

market

funds,

are

valued

based

upon

the

reported

NAV

of

such

investments.

Fair

value

methods

used

by

the

Adviser

for

the

period included,

but were

not

limited

to,

obtaining

market

quotations

from

secondary

pricing

services,

broker-dealers,

or

widely

used

quotation

systems.

General

factors

considered

in

determining

the

fair

value

of

securities

include

fundamental

analytical

data,

the

nature

and

duration

of

any

restrictions

on

disposition

of

the

securities,

and

an

evaluation

of

the

forces

that

influence

the

market

in

which

the

investments

are

purchased

and

sold.

These

securities

are

either

categorized

as

Level

2

or

3

depending

on

the

relevant

inputs

used.

In

the

event

that

the

security

or

asset

could

not be

valued

pursuant

to

one

of

the

valuation

methods

used

by

the

Adviser,

the

value

of

the

security

or

asset was

determined

in

good

faith

by

the Adviser,

as

the

valuation

designee.

When

the

Fund

uses

these

fair

valuation

methods that

use

significant

unobservable

inputs

to

determine

NAV,

securities

will

be

priced

by

a

method

that

the

Adviser

believes

accurately

reflects

fair

value

and

are

categorized

as

Level

3

of

the

fair

value

hierarchy.

These

methods

may

require

subjective

determinations

about

the

value

of

a

security.

While

the

Fund’s

policy

is

intended

to

result

in

a

calculation

of

its

NAV

that

fairly

reflects

security

values

as

of

the

time

of

pricing,

the

Fund

cannot

guarantee

that

values

determined

by

the

Adviser

would

accurately

reflect

the

price

that

the

Fund

could

obtain

for

a

security

if

it

were

to

dispose

of

that

security

as

of

the

time

of

pricing

(for

instance,

in

a

forced

or

distressed

sale).

The

prices

used

by

the

Fund

may

differ

from

the

value

that

would

be

realized

if

the

securities

were

sold.

Fair

Value

Measurements

Various

inputs

are

used

in

determining

the

fair

value

of

investments,

which

are

as

follows:

*

Level

1

-

unadjusted

quoted

prices

in

active

markets

for

identical

securities

*

Level

2

-

other

significant

observable

inputs

(including

quoted

prices

for

similar

securities,

interest

rates,

prepayment

speeds,

credit

risk,

etc.)

*

Level

3

-

significant

unobservable

inputs

that

are

not

corroborated

observable

market

data

The

inputs

or

methodology

used

for

valuing

investments

are

not

necessarily

an

indication

of

the

risk

associated

with

investing

in

those

investments

and

the

determination

of

the

significance

of

a

particular

input

to

the

fair

value

measurement

in

its

entirety

requires

judgment

and

consideration

of

factors

specific

to

each

security.

The

availability

of

observable

inputs

can

vary

from

security

to

security

and

is

affected

by

a

wide

variety

of

factors,

including,

for

example,

the

type

of

security,

whether

the

security

is

new

and

not

yet

established

in

the

marketplace,

the

liquidity

of

markets,

and

other

characteristics

particular

to

the

security.

To

the

extent

that

valuation

is

based

on

models

or

inputs

that

are

less

observable

or

unobservable

in

the

market,

the

determination

of

fair

value

requires

more

judgment.

Accordingly,

the

degree

of

judgment

exercised

in

determining

fair

value

is

greatest

for

instruments

categorized as

Level

3.

In

periods

of

market

dislocation,

the

observability

of

prices

and

inputs

may

be

reduced

for

many

instruments.

This

condition,

as

well

as

changes

related

to

liquidity

of

investments,

could

cause

a

security

to

be

reclassified

between

Level

1,

Level

2,

or

Level

3.

In

certain

cases,

the

inputs

used

to

measure

fair

value

may

fall

into

different

levels

of

the

fair

value

hierarchy.

In

such

cases,

for

disclosure

purposes

the

level

in

the

fair

value

hierarchy

within

which

the

fair

value

measurement

falls

in

its

entirety

is

determined

based

on

the

lowest

level

input

that

is

significant

to

the

fair

value

measurement

in

its

entirety.
