the

normally

defines

as

the

that

would

be

received

to

sell

an

asset

in

an

orderly

transaction

between

market

participants

at

Valuation

Committee

(the

Valuation

is

an

internal

committee

that

has

been

delegated

certain

responsibilities

by

the

fund’s

Board

of

Directors

(the

to

ensure

that

financial

instruments

are

appropriately

priced

at

fair

value

in

accordance

with

GAAP

and

the

1940

Act.

Subject

to

oversight

by

Board,

the

Valuation

develops

and

oversees

pricing-related

policies

and

procedures

and

approves

all

fair

value

determinations.

Specifically,

the

Valuation

Committee

establishes

policies

and

procedures

used

in

valuing

financial

instruments,

including

those

which

cannot

be

valued

in

accordance

with

using

are

and

provides

guidance

on

internal

controls

and

valuation-related

matters.

The

Valuation

Committee

provides

periodic

reporting

to

the

Board

on

valuation

matters.

Various

valuation

techniques

and

inputs

are

used

to

determine

the

fair

value

of

financial

instruments.

GAAP

establishes

the

following

fair

value

hierarchy

that

categorizes

the

inputs

used

to

measure

fair

value:

Level

1

–

quoted

prices

(unadjusted)

in

active

markets

for

identical

financial

instruments

that

the

can

access

at

the

reporting

date

Level

2

other

that

are

either

directly

or

indirectly

(including,

not

Level

3

–

unobservable

inputs

(including

the fund’s

own

assumptions

in

determining

fair

Observable

inputs

are

developed

using

market

data,

such

as

publicly

available

information

about

actual

events

or

transactions,

and

reflect

the

assumptions

that

market

participants

would

use

to

price

the

financial

instrument.

Unobservable

inputs

are

those

for

which

market

data

are

not

available

and

are

developed

using

the

best

information

available

about

the

assumptions

that

market

participants

would

use

to

price

the

financial

instrument.

GAAP

requires

valuation

techniques

to

maximize

the

use

of

relevant

observable

inputs

and

minimize

the

use

of

unobservable

inputs.

When

multiple

inputs

are

used

to

derive

fair

value,

the

financial

instrument

is

assigned

to

the

level

within

the

fair

value

hierarchy

based

on

the

lowest-level

input

that

is

significant

to

the

fair

value

of

the

financial

instrument.

Input

levels

are

not

necessarily

an

indication

of

the

risk

or

liquidity

associated

with

financial

instruments

at

that

level

but

rather

degree

of

used

the

Valuation

Committee,

in

accordance

with

fair

valuation

policies

and

procedures.

The

objective

of

any

fair

value

pricing

determination

is

to

arrive

at

a

price

that

could

reasonably

be

expected

from

a

current

sale.

Financial

instruments

fair

valued

by

the

Valuation

Committee

are

primarily

private

placements,

restricted

securities,

warrants,

rights,

and

other

securities

that

are

not

publicly

traded.

fair

value

vary

by

type

of

investment

and

may

include

market

or

investment

specific

considerations.

The

Valuation

Committee

typically

will

afford

greatest

weight

to

actual

prices

in

arm’s

length

transactions,

to

the

extent

they

represent

orderly

transactions

between

market

participants,

transaction

information

can

be

reliably

obtained,

and

prices

are

deemed

representative

of

fair

value.

However,

the

Valuation

Committee

may

also

consider

other

valuation

methods

such

as

market-based

valuation

multiples;

a

discount

or

premium

from

market

value

of

a

similar,

freely

traded

security

of

the

same

issuer;

discounted

cash

flows;

yield

to

maturity;

or

some

combination.

Fair

value

determinations

are

reviewed

on

a

regular

basis

and

updated

as

information

becomes

available,

including

actual

purchase

and

sale

transactions

of

the

investment.

Because

any

fair

value

determination

involves

a

significant

amount

of

judgment,

there

is

a

degree

of

subjectivity

inherent

in

such

pricing

decisions,

and

fair

value

prices

determined

by

the

Valuation

Committee

could

differ

from

those

of

other

market

participants.

coronavirus

(COVID-19)

has

resulted

in

disruptions

to

global

business

activity

and

caused

significant

volatility

and

declines

in

global

financial

markets.

In

February

2022,

Russian

forces

entered

Ukraine

and

commenced

an

armed

conflict.

Economic

sanctions

have

since

been

imposed

on

Russia

and

certain

of

its

citizens,

including

the

exclusion

of

Russia

from

the

SWIFT

global

payments

network.

As

a

result, Russian-related

stocks

and

debt

have

since

suffered

significant

declines

in

value.

The

duration

of

the

coronavirus

outbreak

and

the

Russian-Ukraine

conflict,

and

their

effects

on

the

financial

markets,

cannot

be

determined

with

The fund’s

performance

could

be

negatively

impacted

if

the

of

a

were

harmed

by

these

and

such

other

events.

Management

is

actively

monitoring

these
