of

Stan-

Codifica-

TM

(“ASC”),

“Fair

(“ASC

defines

fair

as

the

that

in

an orderly

establishes

a

in

determin-

ing

the

of

Factors

considered

in

may

include,

are

to,

infor-

mation

obtained

by

contacting

the

issuer,

available

information

concerning

other

in

similar

circumstances.

or

used

for

valuing

securities

are

not

necessarily

an

the

of

the

of

a

particular

input

to

the

fair

value

mea-

surement

in

its

entirety

requires

judgment

and

considers

factors

specific

to
