known
as
"the
Accounts”
value
securities
for
which
market
quotations
are
readily
available
at
fair
value,
which
is
determined
using
the
last
reported
sale
price.
If
no
sales
are
reported,
as
is
regularly
the
case
for
some
securities
traded
over-the-counter,
securities
are
valued
using
the
last
reported
bid
price
or
an
evaluated
bid
price
provided
by
a
pricing
service.
Pricing
services
use
modeling
techniques
that
incorporate
security
characteristics
such
as
current
quotations
by
broker/
dealers,
coupon,
maturity,
quality,
type
of
issue,
trading
characteristics,
other
yield
and
risk
factors,
and
other
market
conditions
to
determine
an
evaluated
bid
price,
or
in
the
case
of
certain
credit
default
swaps,
a
mean
price
provided
by
a
pricing
service.
When
reliable
market
quotations
are
not
considered
to
be
readily
available,
which
may
be
the
case,
for
example,
with
respect
to
restricted
securities,
certain
debt
securities,
preferred
stocks
and
foreign
securities,
the
investments
are
valued
at
their
fair
value
as
determined
in
good
faith
by
Principal
Global
Investors,
LLC
(the
“Manager”)
under
procedures
established
and
periodically
reviewed
by
the
Accounts’
Board
of
Directors.
The
value
of
foreign
securities
used
in
computing
the
net
asset
value
per
share
is
generally
determined
as
of
the
close
of
the
foreign
exchange
where
the
security
is
principally
traded.
Events
that
occur
after
the
close
of
the
applicable
foreign
market
or
exchange
but
prior
to
the
calculation
of
the
Funds’
net
asset
value
are
reflected
in
the
Funds’
net
asset
value
and
these
securities
are
valued
at
fair
value.
Many
factors,
provided
by
independent
pricing
services,
are
reviewed
in
the
course
of
making
a
good
faith
determination
of
a
security’s
fair
value,
including,
but
not
limited
to,
price
movements
in
American
Depository
Receipts
(“ADRs”),
futures
contracts,
industry
indices,
general
indices,
and
foreign
currencies.
To
the
extent
the
Fund
invests
in
foreign
securities
listed
on
foreign
exchanges
which
trade
on
days
on
which
the
Fund
does
not
determine
net
asset
value,
for
example
weekends
and
other
customary
national
U.S.
holidays,
the
Fund’s
net
asset
value
could
be
significantly
affected
on
days
when
shareholders
cannot
purchase
or
redeem
shares.
Certain
securities
issued
by
companies
in
emerging
market
countries
may
have
more
than
one
quoted
valuation
at
any
given
point
in
time,
sometimes
referred
to
as
a
"local"
price
and
a
"premium"
price.
The
premium
price
is
often
a
negotiated
price,
which
may
not
consistently
represent
a
price
at
which
a
specific
transaction
can
be
affected.
It
is
the
policy
of
the
Fund
to
value
such
securities
at
prices
at
which
it
is
expected
those
shares
may
be
sold,
and
the
Manager
or
any
Sub-Advisor
is
authorized
to
make
such
determinations
subject
to
such
oversight
by
the
Board
as
may
occasionally
be
necessary.
Fair
value
is
defined
as
the
price
that
the
Fund
would
receive
upon
selling
a
security
in
a
timely
transaction
to
an
independent
buyer
in
the
principal
or
most
advantageous
market
of
the
security
at
the
measurement
date.
In
determining
fair
value,
the
Fund
may
use
one
or
more
of
the
following
approaches:
market,
income
and/or
cost.
A
hierarchy
for
inputs
is
used
in
measuring
fair
value
that
maximizes
the
use
of
observable
inputs
and
minimizes
the
use
of
unobservable
inputs
by
requiring
that
the
most
observable
inputs
be
used
when
available.
Observable
inputs
are
inputs
that
reflect
the
assumptions
market
participants
would
use
in
pricing
the
asset
or
liability
developed
based
on
market
data
obtained
from
sources
independent
of
the
Fund.
Unobservable
inputs
are
inputs
that
reflect
the
Fund’s
own
estimates
about
the
estimates
market
participants
would
use
in
pricing
the
asset
or
liability
developed
based
on
the
best
information
available
in
the
circumstances.
September

The
three-tier
hierarchy
of
inputs
is
summarized
in
the
three
broad
levels
listed
below.
Level
1
–
Quoted
prices
are
available
in
active
markets
for
identical
securities
as
of
the
reporting
date.
Investments
which
are
generally
included
in
this
category
include
listed
equities
and
listed
derivatives.
Level
2
–
Other
significant
observable
inputs
(including
quoted
prices
for
similar
investments,
interest
rates,
prepayment
speeds,
credit
risk,
etc.)
Investments
which
are
generally
included
in
this
category
include
certain
foreign
equities,
corporate
bonds,
municipal
bonds,
OTC
derivatives,
senior
floating
rate
interests,
and
US
Government
and
Government
Agency
Obligations.
Level
3
–
Significant
unobservable
inputs
(including
the
Fund’s
assumptions
in
determining
the
fair
value
of
investments).
Investments
which
are
generally
included
in
this
category
include
certain
common
stocks,
convertible
preferred
stocks,
corporate
bonds,
preferred
stocks,
or
senior
floating
rate
interests.
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
market
place,
and
other
characteristics
particular
to
the
transaction.
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
by
the
Fund
in
determining
fair
value
is
greatest
for
instruments
categorized
in
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
in
its
entirety
falls
is
determined
based
on
the
lowest
level
input
that
is
significant
to
the
fair
value
measurement
in
its
entirety.
Fair
value
is
a
market-based
measure
considered
from
the
perspective
of
a
market
participant
who
holds
the
asset
rather
than
an
entity
specific
measure.
Therefore,
even
when
market
assumptions
are
not
readily
available,
the
Fund’s
own
assumptions
are
set
to
reflect
those
that
market
participants
would
use
in
pricing
the
asset
or
liability
at
the
measurement
date.
The
Fund
uses
prices
and
inputs
that
are
current
as
of
the
measurement
date,
when
available.
Investments
which
are
included
in
the
Level
3
category
may
be
valued
using
quoted
prices
from
brokers
and
dealers
participating
in
the
market
for
these
investments.
These
investments
are
classified
as
Level
3
investments
due
to
the
lack
of
market
transparency
and
market
corroboration
to
support
these
quoted
prices.
Valuation
models
may
be
used
as
the
pricing
source
for
other
investments
classified
as
Level
3.
Benchmark
pricing
procedures
set
the
base
price
of
a
security
based
on
current
market
data.
The
base
price
may
be
a
broker-dealer
quote,
transaction
price,
or
internal
value
based
on
relevant
market
data.
The
fair
values
of
these
securities
are
dependent
on
economic,
political,
and
other
considerations.
The
values
of
such
securities
may
be
affected
by
significant
changes
in
the
economic
conditions,
changes
in
government
policies,
and
other
factors
(e.g.,
natural
disasters,
pandemics,
accidents,
conflicts,
etc.).

following
is
