2. Financial
Instrument
Valuation
The
Funds’
investments
in
financial
instruments
are
carried
at
fair
value
daily.
Fair
value
is
the
price
that
would
be
received
to
sell
an
asset
or
paid
to
transfer
a
liability
in
an
orderly
transaction
between
market
participants
on
the
measurement
date.
The
Funds
calculate
the
net
asset
value
(NAV)
per
share
each
business
day
as
of
4
p.m.
Eastern
time
or
the
regularly
scheduled
close
of
the
New
York
Stock
Exchange
(NYSE),
whichever
is
earlier.
Under
compliance
policies
and
procedures
approved
by
the
Trust’s
Board
of
Trustees
(the
Board),
the
Board
has
designated
the
Funds'
investment
manager
as
the
valuation
designee
and
has
responsibility
for
oversight
of
valuation.
The
investment
manager
is
assisted
by
the
Funds'
administrator
in
performing
this
responsibility,
including
leading
the
cross-functional
Valuation
Committee
(VC).
The
Funds
may
utilize
independent
pricing
services,
quotations
from
securities
and
financial
instrument
dealers,
and
other
market
sources
to
determine
fair
value. 
Equity
securities
and
derivative
financial instruments listed
on
an
exchange
or
on
the
NASDAQ
National
Market
System
are
valued
at
the
last
quoted
sale
price
or
the
official
closing
price of
the
day,
respectively.
Foreign
equity
securities
are
valued
as
of
the
close
of
trading
on
the
foreign
stock
exchange
on
which
the
security
is
primarily
traded
or
as
of
4
p.m.
Eastern
time.
The
value
is
then
converted
into
its
U.S.
dollar
equivalent
at
the
foreign
exchange
rate
in
effect
at
4
p.m.
Eastern
time
on
the
day
that
the
value
of
the
security
is
determined.
Over-the-counter
(OTC)
securities
are
valued
within
the
range
of
the
most
recent
quoted
bid
and
ask
prices.
Securities
that
trade
in
multiple
markets
or
on
multiple
exchanges
are
valued
according
to
the
broadest
and
most
representative
market.
Certain
equity
securities
are
valued
based
upon
fundamental
characteristics
or
relationships
to
similar
securities. 
Debt
securities
generally
trade
in
the
OTC
market
rather
than
on
a
securities
exchange.
The
Funds’
pricing
services
use
multiple
valuation
techniques
to
determine
fair
value.
In
instances
where
sufficient
market
activity
exists,
the
pricing
services
may
utilize
a
market-based
approach
through
which
quotes
from
market
makers
are
used
to
determine
fair
value.
In
instances
where
sufficient
market
activity
may
not
exist
or
is
limited,
the
pricing
services
also
utilize
proprietary
valuation
models
which
may
consider
market
characteristics
such
as
benchmark
yield
curves,
credit
spreads,
estimated
default
rates,
anticipated
market
interest
rate
volatility,
coupon
rates,
anticipated
timing
of
principal
repayments,
underlying
collateral,
and
other
unique
security
features
in
order
to
estimate
the
relevant
cash
flows,
which
are
then
discounted
to
calculate
the
fair
value.
Investments
in
open-end
mutual
funds
are
valued
at
the
closing
NAV.
Certain
derivative
financial
instruments
trade
in
the
OTC
market.
The
Funds’
pricing
services
use
various
techniques
including
industry
standard
option
pricing
models
and
proprietary
discounted
cash
flow
models
to
determine
the
fair
value
of
those
instruments.
The
Funds’ net
benefit
or
obligation
under
the
derivative
contract,
as
measured
by
the
fair
value
of
the
contract,
is
included
in
net
assets. 
The
Funds
have procedures
to
determine
the
fair
value
of
financial
instruments
for
which
market
prices
are
not
reliable
or
readily
available.
Under
these
procedures,
the
Funds
primarily employ
a
market-based
approach
which
may
use
related
or
comparable
assets
or
liabilities,
recent
transactions,
market
multiples,
and
other
relevant
information
for
the
investment
to
determine
the
fair
value
of
the
investment.
An
income-based
valuation
approach
may
also
be
used
in
which
the
anticipated
Putnam
Investment
Funds
Notes
to
Schedules
of
Investments
(unaudited)
14
Quarterly
Schedules
of
Investments
future
cash
flows
of
the
investment
are
discounted
to
calculate
fair
value.
Discounts
may
also
be
applied
due
to
the
nature
or
duration
of
any
restrictions
on
the
disposition
of
the
investments.
Due
to
the
inherent
uncertainty
of
valuations
of
such
investments,
the
fair
values
may
differ
significantly
from
the
values
that
would
have
been
used
had
an
active
market
existed. 
Trading
in
securities
on
foreign
securities
stock
exchanges
and
OTC
markets
may
be
completed
before
4
p.m.
Eastern
time.
In
addition,
trading
in
certain
foreign
markets
may
not
take
place
on
every
Funds’ business
day.
Events
can
occur
between
the
time
at
which
trading
in
a
foreign
security
is
completed
and
4
p.m.
Eastern
time
that
might
call
into
question
the
reliability
of
the
value
of
a
portfolio
security
held
by
the
Fund.
As
a
result,
differences
may
arise
between
the
value
of
the
Funds’
portfolio
securities
as
determined
at
the
foreign
market
close
and
the
latest
indications
of
value
at
4
p.m.
Eastern
time.
In
order
to
minimize
the
potential
for
these
differences,
an
independent
pricing
service
may
be
used
to
adjust
the
value
of
the
Funds'
portfolio
securities
to
the
latest
indications
of
fair
value
at 4
p.m.
Eastern
time.
At
April
30,
2026,
certain
securities
may
have
been
fair
valued
using
these
procedures,
in
which
case
the
securities
were
categorized
as
Level
2
within
the
fair
value
hierarchy
(referred
to
as
"market
level
fair
value").
See
the
Fair
Value
Measurements
note
for
more
information.
When
the
last
day
of
the
reporting
period
is
a
non-business
day,
certain
foreign
markets
may
be
open
on
those
days
that
the
Funds’
NAV
is
not
calculated,
which
could
result
in
differences
between
the
value
of
the
Funds’
portfolio securities
on
the
last
business
day
and
the
last
calendar
day
of
the
reporting
period.
Any
security
valuation
changes
due
to
an
open
foreign
market
are
adjusted
and
reflected
by
the
Funds for
financial
reporting
purposes.

Investments
in
Affiliated
Management
Investment
Companies
Certain
or
all
Funds
invest
in
one
or
more
affiliated
management
investment
companies.
As
defined
in
the
1940
Act,
an
investment
is
deemed
to
be
a
“Controlled
Affiliate”
of
a
fund
when
a
fund
owns,
either
directly
or
indirectly,
25%
or
more
of
the
affiliated
fund’s
outstanding
shares
or
has
the
power
to
exercise
control
over
management
or
policies
of
such
fund.
The
Funds
do
not
invest
for
purposes
of
exercising
a
controlling
influence
over
the
management
or
policies.
During
the
period
ended
April
30,

4. Fair
Value
Measurements
The Funds
follow
a
fair
value
hierarchy
that
distinguishes
between
market
data
obtained
from
independent
sources
(observable
inputs)
and
the Funds'
own
market
assumptions
(unobservable
inputs).
These
inputs
are
used
in
determining
the
value
of
the Funds' financial
instruments
and
are
summarized
in
the
following
fair
value
hierarchy:
Level
1
quoted
prices
in
active
markets
for
identical
financial
instruments
Level
2
other
significant
observable
inputs
(including
quoted
prices
for
similar
financial
instruments,
interest
rates,
prepayment
speed,
credit
risk,
etc.)
Level
3
significant
unobservable
inputs
(including
the Funds'
own
assumptions
in
determining
the
fair
value
of
financial
instruments)
The
input
levels
are
not
necessarily
an
indication
of
the
risk
or
liquidity
associated
with
financial
instruments
at
that
level.
