Effective September 30, 2025, the following is added to the beginning of the section titled "Investments, risks and performance" in the Fund's Summary Prospectus and Prospectus:
"Under normal circumstances, the Fund will invest at least 80% of its net assets (plus the amount of borrowings for investment purposes, if any) in equity securities of companies located in the U.S. This policy may be changed only after 60 days' notice to shareholders. Equity securities include common stocks, preferred stocks, and convertible securities. We consider a company to be located in the U.S. if the company's securities trade in the U.S., the company is headquartered or organized in the U.S. or the company derives a majority of its revenues or profits in the U.S."
Effective November 1, 2024 (the "Effective Date"), Putnam Investments Limited ("PIL"), a sub-advisor of the Fund prior to the Effective Date, merged with and into Franklin Templeton Investment Management Limited ("FTIML"), a wholly-owned subsidiary of Franklin Resources, Inc. (the "Merger"). As of the Effective Date, PIL investment professionals became employees of FTIML, and the sub-advisory agreement between Putnam Investment Management, LLC ("Putnam Management") and PIL with respect to the Fund was terminated. In connection with the Merger, the Fund's Trustees approved a new sub-advisory agreement between Putnam Management and FTIML, pursuant to which FTIML became a sub-advisor of the Fund on the Effective Date.
Effective September 5, 2024 (the "Conversion Date"), class B shares of the Fund acquired prior to the Conversion Date converted automatically to class A shares.

HOW HAS THE FUND CHANGED?
Effective September 30, 2025, the Fund's name will be changed to "Putnam U.S. Research Fund".
Effective September 30, 2025, the following is added to the beginning of the section titled "Investments, risks and performance" in the Fund's Summary Prospectus and Prospectus:
"Under normal circumstances, the Fund will invest at least 80% of its net assets (plus the amount of borrowings for investment purposes, if any) in equity securities of companies located in the U.S. This policy may be changed only after 60 days' notice to shareholders. Equity securities include common stocks, preferred stocks, and convertible securities. We consider a company to be located in the U.S. if the company's securities trade in the U.S., the company is headquartered or organized in the U.S. or the company derives a majority of its revenues or profits in the U.S."
Effective November 1, 2024 (the "Effective Date"), Putnam Investments Limited ("PIL"), a sub-advisor of the Fund prior to the Effective Date, merged with and into Franklin Templeton Investment Management Limited ("FTIML"), a wholly-owned subsidiary of Franklin Resources, Inc. (the "Merger"). As of the Effective Date, PIL investment professionals became employees of FTIML, and the sub-advisory agreement between Putnam Investment Management, LLC ("Putnam Management") and PIL with respect to the Fund was terminated. In connection with the Merger, the Fund's Trustees approved a new sub-advisory agreement between Putnam Management and FTIML, pursuant to which FTIML became a sub-advisor of the Fund on the Effective Date.
This is a summary of certain changes to the Fund since August 1, 2024. For more complete information, you may review the Fund's current prospectus and any applicable supplements and the Fund's next prospectus, which we expect to be available by December 1, 2025, at https://www.franklintempleton.com/regulatory-fund-documentsor upon request at (800) 225-1581or
[email protected].
WHERE CAN I FIND ADDITIONAL INFORMATION ABOUT THE FUND?
Additional information is available on https://www.franklintempleton.com/regulatory-fund-documents, including its:
• prospectus • proxy voting information • financial information • holdings • tax information
HOUSEHOLDING
You will receive the Fund's shareholder reports every six months. In addition, you will receive an annual updated summary prospectus (detail prospectus available upon request). To reduce Fund expenses, we try to identify related shareholders in a household and send only one copy of the shareholder reports and summary prospectus. This process, called "householding," will continue indefinitely unless you instruct us otherwise. If you prefer not to have these documents householded, please call us at (800) 225-1581. At any time, you may view current prospectuses/summary prospectuses and shareholder reports on our website. If you choose, you may receive these documents through electronic delivery.

(c) N/A

(d) N/A

(f) Pursuant to Item 19(a) (1), the Registrant is attaching as an exhibit a copy of its code of ethics that applies to its principal executive officers and principal financial and accounting officer.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The Board of Trustees of the Registrant has determined that Gregory G. McGreevey and Manoj P. Singh possess the technical attributes identified in Item 3 to Form N-CSR to qualify as "audit committee financial experts," and has designated Gregory G. McGreevey and Manoj P. Singh as the Audit Committee's financial experts. Gregory G. McGreevey and Manoj P. Singh are "independent" Trustees pursuant to paragraph (a)(2) of Item 3 to Form N-CSR.

Under applicable securities laws, a person determined to be an audit committee financial expert will not be deemed an "expert" for any purpose, including without limitation for the purposes of Section 11 of the Securities Act of 1933, as a result of being designated or identified as an audit committee financial expert. The designation or identification of a person as an audit committee financial expert does not impose on such person any duties, obligations, or liabilities greater than the duties, obligations, and liabilities imposed on such person as a member of the audit committee and board of directors in the absence of such designation or identification. The designation or identification of a person as an audit committee financial expert does not affect the duties, obligations, or liability of any other member of the audit committee or board of directors.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a) Audit Fees. The aggregate fees billed in the last two fiscal years ending July 31, 2024 and July 31, 2025 (the "Reporting Periods") for professional services rendered by the Registrant's principal accountant (the "Auditor") for the audit of the Registrant's annual financial statements, or services that are normally provided by the Auditor in connection with the statutory and regulatory filings or engagements for the Reporting Periods, were $160,953 in July 31, 2024 and $87,936 in July 31, 2025.

(b) Audit-Related Fees. The aggregate fees billed in the Reporting Periods for assurance and related services by the Auditor that are reasonably related to the performance of the Registrant's financial statements were $0 in July 31, 2024 and $0 in July 31, 2025.

(c) Tax Fees. The aggregate fees billed in the Reporting Periods for professional services rendered by the Auditor for tax compliance, tax advice and tax planning ("Tax Services") were $11,828 in July 31, 2024 and $19,714 in July 31, 2025. These services consisted of (i) review or preparation of U.S. federal, state, local and excise tax returns; (ii) U.S. federal, state and local tax planning, advice and assistance regarding statutory, regulatory or administrative developments, and (iii) tax advice regarding tax qualification matters and/or treatment of various financial instruments held or proposed to be acquired or held.

(d) All Other Fees. The aggregate fees billed in the Reporting Periods for products and services provided by the Auditor to the Registrant, other than the services reported in paragraphs (a) through (c) of this item, were $0 in July 31, 2024 and $0 in July 31, 2025.

There were no other non-audit services rendered by the Auditor to the Service Affiliates requiring pre-approval by the Audit Committee in the Reporting Periods.

(e) Audit Committee's pre-approval policies and procedures described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

Pre-Approval Policies of the Audit, Compliance and Risk Committee. The Audit, Compliance and Risk Committee of the Putnam funds has determined that, as a matter of policy, all work performed for the funds by the funds' independent auditors will be pre-approved by the Committee itself and thus will generally not be subject to pre-approval procedures.

The Audit, Compliance and Risk Committee also has adopted a policy to pre-approve the engagement by the fund's investment manager and certain of its affiliates of the fund's independent auditors, even in circumstances where pre-approval is not required by applicable law. Any such requests by the fund's investment manager or certain of its affiliates are typically submitted in writing to the Committee and explain, among other things, the nature of the proposed engagement, the estimated fees, and why this work should be performed by that particular audit firm as opposed to another one. In reviewing such requests, the Committee considers, among other things, whether the provision of such services by the audit firm are compatible with the independence of the audit firm.

(2) None of the services described in paragraphs (b) through (d) of this Item were performed in reliance on paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not applicable.

(g) Non-audit fees billed by the Auditor for services rendered to the Registrant and the Service Affiliates during the reporting period were $1,030,797 in July 31, 2024 and $583,796 in July 31, 2025.

(h) Yes. The Registrant's Audit Committee has considered whether the provision of non-audit services that were rendered to Service Affiliates, which were not pre-approved (not requiring pre-approval), is compatible with maintaining the Auditor's independence. All services provided by the Auditor to the Registrant or to the Service Affiliates, which were required to be pre-approved, were pre-approved as required.

(i) Not applicable.

(j) Not applicable

Putnam
Research
Fund
will

Putnam
U.S.
Research
Fund.
The
following
summarizes
the
Fund
's
significant
accounting
policies.
a.
Financial
Instrument
Valuation
The
Fund's
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
Fund
calculates
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
Fund's
investment
manager
as
the
valuation
designee
and
has
responsibility
for
oversight
of
valuation.
The
investment
manager
is
assisted
by
the
Fund's
administrator
in
performing
this
responsibility,
including
leading
the
cross-
functional
Valuation
Committee
(VC).
The
Fund
may
utilize
independent
pricing
services,
quotations
from
securities
and
financial
instrument
dealers,
and
other
market
sources
to
determine
fair
value.
Equity
securities
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
Fund's
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
Fund's
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
Fund's
net
benefit
or
obligation
under
the
derivative
contract,
as
measured
by
the
fair
value
of
the
contract,
is
included
in
net
assets.
The
Fund
has
procedures
to
determine
the
fair
value
of
financial
instruments
for
which
market
prices
are
not
reliable
or
readily
available.
Under
these
procedures,
Putnam
Investment
Funds
Notes
to
Financial
Statements
19
franklintempleton.com
Annual
Report
Putnam
Research
Fund
(continued)
the Fund
primarily
employs
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
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
Fund's
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
Fund's
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
Fund's
portfolio
securities
to
the
latest
indications
of
fair
value
at
4
p.m.
Eastern
time.
At
July
31,
2025,
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
Fund's
NAV
is
not
calculated,
which
could
result
in
differences
between
the
value
of
the
Fund's
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
Fund
for
financial
reporting
purposes.
b.
Foreign
Currency
Translation
Portfolio
securities
and
other
assets
and
liabilities
denominated
in
foreign
currencies
are
translated
into
U.S.
dollars
based
on
the
exchange
rate
of
such
currencies
against
U.S.
dollars
on
the
date
of
valuation.
The
Fund
may
enter
into
foreign
currency
exchange
contracts
to
facilitate
transactions
denominated
in
a
foreign
currency.
Purchases
and
sales
of
securities,
income
and
expense
items
denominated
in
foreign
currencies
are
translated
into
U.S.
dollars
at
the
exchange
rate
in
effect
on
the
transaction
date.
Portfolio
securities
and
assets
and
liabilities
denominated
in
foreign
currencies
contain
risks
that
those
currencies
will
decline
in
value
relative
to
the
U.S.
dollar.
Occasionally,
events
may
impact
the
availability
or
reliability
of
foreign
exchange
rates
used
to
convert
the
U.S.
dollar
equivalent
value.
If
such
an
event
occurs,
the
foreign
exchange
rate
will
be
valued
at
fair
value
using
procedures
established
and
approved
by
the
Board.
The
Fund
does
not
separately
report
the
effect
of
changes
in
foreign
exchange
rates
from
changes
in
market
prices
on
securities
held.
Such
changes
are
included
in
net
realized
and
unrealized
gain
or
loss
from
investments
in
the
Statement of
Operations.
Realized
foreign
exchange
gains
or
losses
arise
from
sales
of
foreign
currencies,
currency
gains
or
losses
realized
between
the
trade
and
settlement
dates
on
securities
transactions
and
the
difference
between
the
recorded
amounts
of
dividends,
interest,
and
foreign
withholding
taxes
and
the
U.S.
dollar
equivalent
of
the
amounts
actually
received
or
paid.
Net
unrealized
foreign
exchange
gains
and
losses
arise
from
changes
in
foreign
exchange
rates
on
foreign
denominated
assets
and
liabilities
other
than
investments
in
securities
held
at
the
end
of
the
reporting
period.
c.
Derivative
Financial
Instruments
The
Fund invested
in
derivative
financial
instruments
in
order
to
manage
risk
or
gain
exposure
to
various
other
investments
or
markets.
Derivatives
are
financial
contracts
based
on
an
underlying
or
notional
amount,
require
no
initial
investment
or
an
initial
net
investment
that
is
smaller
than
would
normally
be
required
to
have
a
similar
response
to
changes
in
market
factors,
and
require
or
permit
net
settlement.
Derivatives
contain
various
risks
including
the
potential
inability
of
the
counterparty
to
fulfill
their
obligations
under
the
terms
of
the
contract,
the
potential

an
illiquid
secondary
market,
and/or
the
potential
for
market
movements
which
expose
the
Fund
to
gains
or
losses
in
excess
of
the
amounts
shown
in
the
Statement
of
Assets
and
Liabilities.
Realized
gain
and
loss
and
unrealized
appreciation
and
depreciation
on
these
contracts
for
the
period
are
included
in
the
Statement
of
Operations.
Derivative
counterparty
credit
risk
is
managed
through
a
formal
evaluation
of
the
creditworthiness
of
all
potential
counterparties.
The
Fund
attempts
to
reduce
its
exposure
to
counterparty
credit
risk
on
OTC
derivatives,
whenever
possible,
by
entering
into
International
Swaps
and
Derivatives
Association
(ISDA)
master
agreements
with
certain
counterparties.
These
agreements
contain
various
provisions,
including
but
not
limited
to
collateral
requirements,
events
of
default,
or
early
termination.
Termination
events
applicable
to
the
counterparty
include
certain
deteriorations
in
the
credit
quality
of
the
counterparty.
Termination
events
applicable
to
the
Fund
include
failure
of
the
Fund
to
maintain
certain
net
asset
levels
and/or
limit
the
decline
in
net
assets
over
various
periods
of
time.
In
the
event
of
default
or
early
termination,
the
ISDA
master
agreement
gives
the
non-defaulting
party
the
right
to
net
and
close-out
all
transactions
traded,
whether
or
not
arising
under
the
ISDA
agreement,
to
one
net
amount
payable
by
one
counterparty
to
the
other.
However,
absent
an
event
of
default
or
early
termination,
OTC
derivative
assets
and
liabilities
are
presented
gross
and
not
offset
in
the
Statement
of
Assets
and
Liabilities.
Early
termination
by
the
counterparty
may
result
in
an
immediate
payment
by
the
Fund
of
any
net
liability
owed
to
that
counterparty
under
the
ISDA
agreement.
Collateral
requirements
differ
by
type
of
derivative.
Collateral
terms
are
contract
specific
for
OTC
derivatives.
For
OTC
derivatives
traded
under
an
ISDA
master
agreement,
posting
of
collateral
is
required
by
either
the
Fund
or
the
applicable
counterparty
if
the
total
net
exposure
of
all
OTC
derivatives
with
the
applicable
counterparty
exceeds
the
minimum
transfer
amount,
which
typically
ranges
from
$100,000
to
$250,000,
and
can
vary
depending
on
the
counterparty
and
the
type
of
agreement.
Generally,
collateral
is
determined
at
the
close
of
Fund
business
each
day
and
any
additional
collateral
required
due
to
changes
in
derivative
values
may
be
delivered
by
the
Fund
or
the
counterparty
the
next
business
day,
or
within
a
few
business
days.
Collateral
pledged
and/or
received
by
the
Fund,
if
any,
is
held
in
segregated
accounts
with
the
Fund's
custodian/counterparty
broker
and
can
be
in
the
form
of
cash
and/or
securities.
Unrestricted
cash
may
be
invested
according
to
the
Fund's
investment
objectives.
To
the
extent
that
the
amounts
due
to
the
Fund
from
its
counterparties
are
not
subject
to
collateralization
or
are
not
fully
collateralized,
the
Fund
bears
the
risk
of
loss
from
counterparty
non-performance.
The
Fund entered
into
OTC
forward
exchange
contracts
primarily
to
manage
and/or
gain exposure
to
certain
foreign
currencies.
A
forward
exchange
contract
is
an
agreement
between
the
Fund
and
a
counterparty
to
buy
or
sell
a
foreign
currency at
a
specific
exchange
rate
on
a
future
date.
Forward
exchange
contracts
outstanding
at
period
end,
if
any,
are
listed
in
the
Fund's
Schedule
of
Investments.
The
Fund entered
into
exchange
traded
futures
contracts
primarily
to
manage
and/or
gain
exposure
to equity
price
risk.
A
futures
contract
is
an
agreement
between
the
Fund
and
a
counterparty
to
buy
or
sell
an
asset
at
a
specified
price
on
a
future
date.
Required
initial
margins
are
pledged
by
the
Fund,
and
the
daily
change
in
fair
value
is
accounted
for
as
a
variation
margin
payable
or
receivable
in
the
Statement
of
Assets
and
Liabilities.
Futures
contracts
outstanding
at
period
end,
if
any,
are
listed
in
the
Fund's
Schedule
of
Investments.
The
Fund
purchased
or
wrote
OTC
option
contracts
primarily
to
manage
and/or
gain exposure
to
equity
price
risk.
An
option
is
a
contract
entitling
the
holder
to
purchase
or
sell
a
specific
amount
of
shares
or
units
of
an
asset
or
notional
amount
of
a
swap
(swaption),
at
a
specified
price.
When
an
option
is
purchased
or
written,
an
amount
equal
to
the
premium
paid
or
received
is
recorded
as
an
asset
or
liability,
respectively.
Upon
exercise
of
an
option,
the
acquisition
cost
or
sales
proceeds
of
the
underlying
investment
is
adjusted
by
any
premium
received
or
paid.
Upon
expiration
of
an
option,
any
premium
received
or
paid
is
recorded
as
a
realized
gain
or
loss.
Upon
closing
an
option
other
than
through
expiration
or
exercise,
the
difference
between
the
premium
received
or
paid
and
the
cost
to
close
the
position
is
recorded
as
a
realized
gain
or
loss.
Option
contracts
outstanding
at
period
end,
if
any,
are
listed
in
the
Fund's
Schedule
of
Investments.

d.
Income
and
Deferred
Taxes
It
is the Fund's
policy
to
qualify
as
a
regulated
investment
company
under
the
Internal
Revenue
Code. The Fund
intends
to
distribute
to
shareholders
substantially
all
of
its
taxable
income
and
net
realized
gains
to
relieve
it
from
federal
income
and if
applicable,
excise
taxes.
As
a
result,
no
provision
for
U.S.
federal
income
taxes
is
required.
The Fund
may
be
subject
to
foreign
taxation
related
to
income
received,
capital
gains
on
the
sale
of
securities
and
certain
foreign
currency
transactions
in
the
foreign
jurisdictions
in
which
it
invests.
Foreign
taxes,
if
any,
are
recorded
based
on
the
tax
regulations
and
rates
that
exist
in
the
foreign
markets
in
which
the
Fund
invests.
When
a
capital
gain
tax
is
determined
to
apply,
the
Fund
records
an
estimated
deferred
tax
liability
in
an
amount
that
would
be
payable
if
the
securities
were
disposed
of
on
the
valuation
date.
The Fund
may
recognize
an
income
tax
liability
related
to
its
uncertain
tax
positions
under
U.S.
GAAP
when
the
uncertain
tax
position
has
a
less
than
50%
probability
that
it
will
be
sustained
upon
examination
by
the
tax
authorities
based
on
its
technical
merits.
As
of
July
31,
2025, the Fund
has
determined
that
no
tax
liability
is
required
in
its
financial
statements
related
to
uncertain
tax
positions
for
any
open
tax
years
(or
expected
to
be
taken
in
future
tax
years).
Open
tax
years
are
those
that
remain
subject
to
examination
and
are
based
on
the
statute
of
limitations
in
each
jurisdiction
in
which
the Fund
invests.
e.
Security
Transactions,
Investment
Income,
Expenses
and
Distributions
Security
transactions
are
accounted
for
on
trade
date.
Realized
gains
and
losses
on
security
transactions
are
determined
on
a
specific
identification basis.
Interest
income
(including
interest
income
from
payment-in-kind
securities,
if
any)
and
estimated
expenses
are
accrued
daily.
Amortization
of
premium
and
accretion
of
discount
on
debt
securities
are
included
in
interest
income.
Dividend
income
is recorded
on
the
ex-dividend
date
except
for
certain
dividends
from
securities
where
the
dividend
rate
is
not available.
In
such
cases,
the
dividend
is
recorded
as
soon
as
the
information
is
received
by
the Fund.
Distributions
to
shareholders
are
recorded
on
the
ex-dividend
date.
Distributions
from
realized
capital
gains
and
other
distributions,
if
any,
are
recorded
on
the
ex-dividend
date.
Distributable
earnings are
determined
according
to
income
tax
regulations
(tax
basis)
and
may
differ
from
earnings recorded
in
accordance
with
U.S.
GAAP.
These
differences
may
be
permanent
or
temporary.
Permanent differences
are
reclassified
among
capital
accounts
to
reflect
their
tax
character.
These reclassifications
have
no
impact
on
net
assets
or
the
results
of
operations.
Temporary
differences are
not
reclassified,
as
they
may
reverse
in
subsequent
periods.
Common
expenses
incurred
by
the
Trust
are
allocated
among
the
Funds
based
on
the
ratio
of
net
assets
of
each
Fund
to
the
combined
net
assets
of
the
Trust
or
based
on
the
ratio
of
number
of
shareholders
of
each
Fund
to
the
combined
number
of
shareholders
of
the
Trust.
Fund
specific
expenses
are
charged
directly
to
the
Fund
that
incurred
the
expense.
Realized
and
unrealized
gains
and
losses
and
net
investment
income,
excluding
class
specific
expenses,
are
allocated
daily
to
each
class
of
shares
based
upon
the
relative
proportion
of
net
assets
of
each
class.
Differences
in
per
share
distributions
by
class
are
generally
due
to
differences
in
class
specific
expenses.
f.
Accounting
Estimates
The
preparation
of
financial
statements
in
accordance
with
U.S.
GAAP
requires
management
to
make
estimates
and
assumptions
that
affect
the
reported
amounts
of
assets
and
liabilities
at
the
date
of
the
financial
statements
and
the
amounts
of
income
and
expenses
during
the
reporting
period.
Actual
results
could
differ
from
those
estimates.
g.
Guarantees
and
Indemnifications
Under
the Trust's
organizational
documents,
its
officers
and trustees
are
indemnified
by
the Trust against
certain
liabilities
arising
out
of
the
performance
of
their
duties
to
the
Trust.
Additionally,
in
the
normal
course
of
business,
the Trust,
on
behalf
of
the
Fund, enters
into
contracts
with
service
providers
that
contain
general
indemnification
clauses.
The Trust's
maximum
exposure
under
these
arrangements
is
unknown
as
this
would
involve
future
claims
that
may
be
made
against
the Trust
that
have
not
yet
occurred.
Currently,
the Trust
expects
the
risk
of
loss
to
be
remote.

Investments
in
Affiliated
Management
Investment
Companies
The
Fund
invests
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

policies
of
such
fund.
The
Fund
does
not
invest
for
purposes
of
exercising
a

Management
fees
paid
by
the
Fund
are
waived
on
assets
invested
in

Expense
Offset
Arrangement
The Fund has entered
into arrangements
with
PSERV
and
its
custodian
whereby
credits
realized
as
a
result
of
uninvested
cash
balances
are
used
to
reduce
a
portion
of
the
Fund's
transfer
agent
and
custodian
fees,
respectively.
During
the
year
ended
July
31,
2025,
the
fees
were
reduced
as
noted
in
the
Statement
of
Operations.
Effective

Taxes
The
tax
character
of

was
as
follows:
At

net
unrealized

(depreciation),
undistributed
ordinary
income
and

tax
purposes
were
as
follows:
Differences
between
income
and/or
capital
gains
as
determined
on
a
book
basis
and
a

are
primarily
due
to
differing

Credit
Facility
Effective
January
31,
2025,
the
Fund,
together
with
other
U.S.
registered
and
foreign
investment
funds
(collectively,
Borrowers)
managed
by
Franklin
Templeton,
are
borrowers
in
a
joint
syndicated
senior
unsecured
credit
facility
totaling
$2.995
billion
(Global
Credit
Facility)
which
matures
on
January
30,
2026.
This
Global
Credit
Facility
provides
a
source
of
funds
to
the
Borrowers
for
temporary
and
emergency
purposes,
including
the
ability
to
meet
future
unanticipated
or
unusually
large
redemption
requests.
Under
the
terms
of
the
Global
Credit
Facility,
the
Fund
shall,
in
addition
to
interest
charged
on
any
borrowings
made
by
the
Fund
and
other
costs
incurred
by
the
Fund,
pay its
share
of
fees
and
expenses
incurred
in
connection
with
the
implementation
and
maintenance
of
the
Global
Credit
Facility,
based
upon its
relative
share
of
the
aggregate
net
assets
of
all
of
the
Borrowers,
including
an
annual
commitment
fee
of
0.15%
based
upon
the
unused
portion
of
the
Global
Credit
Facility.
These
fees
are
reflected
in
other
expenses
in
the
Statement
of
Operations.
During
the
reporting
period,
the
Fund
did
not
use
the
Global
Credit
Facility.
Prior
to
January
31,
2025,
the
Fund
participated,
along
with
other
Putnam

in
a

of
credit,
provided
by

Fair
Value
Measurements
The
Fund
follows
a
fair
value
hierarchy
that
distinguishes
between
market
data
obtained
from
independent
sources
(observable
inputs)
and
the Fund's
own
market
assumptions
(unobservable
inputs).
These
inputs
are
used
in
determining
the
value
of
the
Fund's 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
Fund's
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.
A
summary
of
inputs
used
as
of
July
31,
2025,

The
update
is
limited
to
disclosure
requirements
and
does
not
impact
the Fund's
financial
position
or
results
of
operations.
The Fund operates
as
a
single
operating
segment,
which
is
an
investment
portfolio.
The
Fund's Investment
manager
serves
as
the
Chief
Operating
Decision
Maker
(CODM),
evaluating
fund-wide
results
and
performance
under
a
unified
investment
strategy.
The
CODM
uses
these
measures
to
assess
fund
performance
and
allocate
resources
effectively.
Internal
reporting
provided
to
the
CODM
aligns
with
the
accounting
policies
and
measurement
principles
used
in
the financial
statements.

Fund
Opinion
on
the
Financial
Statements
We
have
audited
the
accompanying
statement
of
assets
and
liabilities,
including
the
schedule
of
investments,
of
Putnam
Research
Fund
(one
of
the
funds
constituting
Putnam
Investment
Funds,
referred
to
hereafter
as
the
"Fund")
as
of
July
31,
2025,
the
related
statement
of
operations
for
the
year
ended
July
31,
2025,
the
statements
of
changes
in
net
assets
for
each
of
the
two
years
in
the
period
ended
July
31,
2025,
including
the
related
notes,
and
the
financial
highlights
for
each
of
the
five
years
in
the
period
ended
July
31,
2025
(collectively
referred
to
as
the
"financial
statements").
In
our
opinion,
the
financial
statements
present
fairly,
in
all
material
respects,
the
financial
position
of
the
Fund
as
of
July
31,
2025,
the
results
of
its
operations
for
the
year
then
ended,
the
changes
in
its
net
assets
for
each
of
the
two
years
in
the
period
ended
July
31,
2025
and
the
financial
highlights
for
each
of
the
five
years
in
the
period
ended
July
31,
2025
in
conformity
with
accounting
principles
generally
accepted
in
the
United
States
of
America.
Basis
for
Opinion
These
financial
statements
are
the
responsibility
of
the
Fund's
management.
Our
responsibility
is
to
express
an
opinion
on
the
Fund's
financial
statements
based
on
our
audits.
We
are
a
public
accounting
firm
registered
with
the
Public
Company
Accounting
Oversight
Board
(United
States)
("PCAOB")
and
are
required
to
be
independent
with
respect
to
the
Fund
in
accordance
with
the
U.S.
federal
securities
laws
and
the
applicable
rules
and
regulations
of
the
Securities
and
Exchange
Commission
and
the
PCAOB.
We
conducted
our
audits
of
these
financial
statements
in
accordance
with
the
standards
of
the
PCAOB.
Those
standards
require
that
we
plan
and
perform
the
audit
to
obtain
reasonable
assurance
about
whether
the
financial
statements
are
free
of
material
misstatement,
whether
due
to
error
or
fraud.
Our
audits
included
performing
procedures
to
assess
the
risks
of
material
misstatement
of
the
financial
statements,
whether
due
to
error
or
fraud,
and
performing
procedures
that
respond
to
those
risks.
Such
procedures
included
examining,
on
a
test
basis,
evidence
regarding
the
amounts
and
disclosures
in
the
financial
statements.
Our
audits
also
included
evaluating
the
accounting
principles
used
and
significant
estimates
made
by
management,
as
well
as
evaluating
the
overall
presentation
of
the
financial
statements.
Our
procedures
included
confirmation
of
securities
owned
as
of
July
31,
2025
by
correspondence
with
the
custodian,
transfer
agent
and
brokers.
We
believe
that
our
audits
provide
a
reasonable
basis
for
our
opinion.

At
their

on

the
Board
of

("Board")
of
your

including
all
of

who

(as

Act"))
of
the
Putnam
mutual
funds
and

funds
(collectively,
the

(the
"Independent

approved
the
continuance
of

General
conclusions
The
Board
oversees
the
management
of
each
fund
and,
as
required
by
law,
determines
annually
whether
to
approve
the
continuance
of

with
the
Advisor
and
the

contract
with
respect
to

between
the
Advisor
and
each
Subadvisor.
Because
the
Subadvisors
are
affiliates
of
the
Advisor
and
the

remains
fully
responsible
for
all

provided
by
the

All

the
Board's
considerations
should
be
deemed
to
include
references
to
the
applicable
Subadvisor
as
necessary
or

in
the
context.
The
Board,
with
the
assistance
of
its
Contract
Committee,
requests
and
evaluates
all
information
it
deems
reasonably
necessary
under
the
circumstances
in
connection
with
its
annual
contract
review.
The
Contract
Committee
consists
solely
of
Independent
Trustees.
At
the
outset
of
the
review
process,
the
Board's
independent
staff
and
independent
legal
counsel,
as
defined
in
Rule
0-1(a)
(6)
under
the
1940
Act
(their
"independent
legal
counsel"),
considered
any
possible
changes
to
the
annual
contract
review
materials
furnished
to
the
Contract
Committee
in
prior
years
and,
as
applicable,
identified
those
changes
to
the
Advisor.
Following
these
discussions
and
in
consultation
with
the
Contract
Committee,
the
Independent
Trustees'
independent
legal
counsel
submitted
an
initial
request
that
the
Advisor
and
its
affiliates
furnish
specified
information,
together
with
any
additional
information
the
Advisor
considered
relevant,
to
the
Contract
Committee.
Over
the
course
of
several
months
ending
in
June
2025,
the
Contract
Committee
met
on
a
number
of
occasions
with
representatives
of
the
Advisor,
and
separately
in
executive
session,
to
consider
the
information
that
the
Advisor
provided,
including
information
provided
in
response
to
supplemental
requests
submitted
by
independent
legal
counsel.
Throughout
this
process,
the
Contract
Committee
was
assisted
by
the
Board's
independent
staff
and
by
independent
legal
counsel.
At
the
Board's
June
2025
meeting,
the
Contract
Committee
met
in
executive
session
to
discuss
and
consider
its
recommendations
with
respect
to
the
continuance
of
the
Management
Contracts.
At
that
meeting,
the
Contract
Committee
also
met
in
executive
session
with
the
other
Independent
Trustees
to
review
a
summary
of
the
process
undertaken
by
the
Contract
Committee
and
key
information
that
the
Contract
Committee
considered
in
the
course
of
its
review.
The
Contract
Committee
then
presented
its
written
report,
which
summarized
the
key
factors
that
the
Committee
had
considered
and
set
forth
its
recommendations.
The
Contract
Committee
recommended,
and
the
Independent
Trustees
approved,
the
continuance
of
your
fund's
Management
Contracts,
effective
July
1,
2025.
In
considering
the
continuance
of
the
Management
Contracts,
the
Board
took
into
account
a
number
of
factors,
including:
1.
That
the
fee
schedule
in
effect
for
your
fund
represented
reasonable
compensation
in
light
of
the
nature
and
quality
of
the
services
being
provided
to
the
fund,
the
fees
paid
by
competitive
funds,
the
costs
incurred
by
the
Advisor
in
providing
services
to
the
fund
and
the
application
of
certain
reductions
and
waivers
noted
below;
2.
That
the
fee
schedule
in
effect
for
your
fund
represented
an
appropriate
sharing
between
fund
shareholders
and
the
Advisor
of
any
economies
of
scale
that
may
exist
in
the
management
of
the
fund
at
current
asset
levels;
3.
That
the
funds
benefited,
and
were
expected
to
continue
to
benefit,
from
Franklin
Templeton's
large
retail
and
institutional
global
distribution
capabilities
and
significant
network
of
intermediary
relationships,
which
may
provide
additional
opportunities
for
the
funds
to
increase
assets
and
reduce
the
impact
of
expenses
by
spreading
them
over
a
larger
asset
base;
4.
Potential
benefits
to
shareholders
of
the
funds
that
could
result
from
the
alignment
of
certain
fund
features
and
shareholder
benefits
with
those
of
other
funds
sponsored
by
the
Advisor
and
its
affiliates
and
access
to
a
broader
array
of
investment
opportunities;
and
5.
The
financial
strength,
reputation,
experience
and
resources
of
Franklin
Templeton
and
its
investment
advisory
subsidiaries.
These
conclusions
were
based
on
a
comprehensive
consideration
of
all
information
provided
to
the
Trustees
and
were
not
the
result
of
any
single
factor.
Some
of
the
factors
that
figured
particularly
in
the
Trustees'
deliberations
and
how
the
Trustees
considered
these
factors
are
described
below,
although
individual
Trustees
may
have
evaluated
the
information
presented
differently,
giving
different
weights
to
various
factors.
It
is
also
important
to
recognize
that
the
management
arrangements
for
your
fund
and
the
other
funds
are
the
result
of
many
years
of
review
and
discussion
between
the
Independent
Trustees
and
management,
occurring
both
in
connection
with
formal
contract
reviews
as
well
as
throughout
the
year
and
that
the
Trustees'
conclusions
may
be
based,
in
part,
on
their
consideration
of
fee
arrangements
in
previous
years.
For
example,
with
certain
exceptions
primarily
involving
newer
funds
(including
the
exchange-traded
funds)
or
repositioned
funds,
the
current
fee
arrangements
under
the
vast
majority
of
the
funds'
management
contracts
were
first
implemented
at
the
beginning
of
2010
following
extensive
review
by
the
Contract
Committee
and
discussions
with
management,
as
well
as
approval
by
shareholders.

Annual
Report
Management
fee
schedules
and
total
expenses
The
Trustees
reviewed
the
management
fee
schedules
in
effect
for
all
funds,
including
fee
levels
and
any
breakpoints.
Under
its
management
contract,
your
fund
has
the
benefit
of
breakpoints
in
its
management
fee
schedule
that
provide
shareholders
with
reduced
fee
levels
as
assets
under
management
of
other
mutual
funds
sponsored
by
the
applicable
Advisor
(or
that
have
been
deemed
to
be
sponsored
by
the
Advisor
for
the
purpose
of
the
management
fee
calculation)
increase.
The
Trustees
also
reviewed
the
total
expenses
of
each
fund,
recognizing
that
in
most
cases
management
fees
represented
the
major,
but
not
the
sole,
determinant
of
total
costs
to
fund
shareholders.
(Two
mutual
funds
and
each
of
the
exchange-traded
funds,
have
implemented
(or,
in
the
case
of
ten
municipal
income
funds
that
are
converting
into
exchange-traded
funds,
will
implement)
so-
called
"all-in"
or
unitary
management
fees
covering
substantially
all
routine
fund
operating
costs.)
In
reviewing
fees
and
expenses,
the
Trustees
generally
focus
their
attention
on
material
changes
in
circumstances
-
for
example,
changes
in
assets
under
management,
changes
in
a
fund's
investment
strategy,
changes
in
the
Advisor's
operating
costs
or
profitability,
or
changes
in
competitive
practices
in
the
fund
industry
-
that
suggest
that
consideration
of
fee
changes
might
be
warranted.
The
Trustees
concluded
that
the
circumstances
did
not
indicate
that
changes
to
the
management
fee
schedule
for
your
fund
would
be
appropriate
at
this
time.
As
in
the
past,
the
Trustees
also
focused
on
the
competitiveness
of
each
fund's
total
expense
ratio.
The
Trustees,
the
Advisor
and
the
funds'
investor
servicing
agent,
Putnam
Investor
Services,
Inc.
("PSERV"),
have
implemented
expense
limitations
that
were
in
effect
during
your
fund's
fiscal
year
ending
in
2024.
These
expense
limitations
were:
(i)
a
contractual
expense
limitation
applicable
to
specified
mutual
funds
(including
your
fund)
of
25
basis
points
on
investor
servicing
fees
and
expenses
and
(ii)
a
contractual
expense
limitation
applicable
to
specified
mutual
funds
(including
your
fund)
of
20
basis
points
on
so-called
"other
expenses"
(i.e.,
all
expenses
exclusive
of
management
fees,
distribution
fees,
investor
servicing
fees,
investment-related
expenses,
interest,
taxes,
brokerage
commissions,
acquired
fund
fees
and
expenses
and
extraordinary
expenses).
These
expense
limitations
attempt
to
maintain
competitive
expense
levels
for
the
funds.
Most
funds
(including
your
fund)
had
sufficiently
low
expenses
that
these
expense
limitations
were
not
operative
during
their
fiscal
years
ending
in
2024.
The
Advisor
and
PSERV
have
agreed
to
maintain
these
expense
limitations
until
at
least
November
30,
2026.
Additionally,
the
Advisor
has
contractually
agreed
to
waive
fees
and/or
reimburse
expenses
for
your
fund
to
the
extent
that
the
total
annual
fund
operating
expenses
for
the
fund
-
exclusive
of
distribution
fees,
investor
servicing
fees,
investment-related
expenses,
interest,
taxes,
brokerage
commissions,
acquired
fund
fees
and
expenses
and
extraordinary
expenses
-
would
exceed
0.49%
through
November
30,
2026.
Further,
PSERV
has
contractually
agreed
to
waive
all
investor
servicing
fees
with
respect
to
Class
Y
and
Class
R6
shares
of
your
fund
through
at
least
November
30,
2026.
This
waiver
applies
prior
to
any
contractual
waiver
agreed
to
by
the
Advisor
with
respect
to
your
fund's
expenses.
The
Advisor
and
PSERV's
commitment
to
these
expense
limitation
arrangements,
which
were
intended
to
support
an
effort
to
have
the
mutual
fund
expenses
meet
competitive
standards,
was
an
important
factor
in
the
Trustees'
decision
to
approve
the
continuance
of
your
fund's
Management
Contracts.
The
Trustees
reviewed
comparative
fee
and
expense
information
for
a
custom
group
of
competitive
funds
selected
by
Broadridge
Financial
Solutions,
Inc.
("Broadridge").
This
comparative
information
included
your
fund's
percentile
ranking
for
effective
management
fees
and
total
expenses
(excluding
any
applicable
12b-1
fees),
which
provides
a
general
indication
of
your
fund's
relative
standing.
In
the
custom
peer
group,
your
fund
ranked
in
the
second
quintile
in
effective
management
fees
(determined
for
your
fund
and
the
other
funds
in
the
custom
peer
group
assuming
the
same
fund
asset
size
for
your
fund
and
the
other
funds
in
the
custom
peer
group
and
the
applicable
contractual
management
fee
schedule)
and
in
the
third
quintile
in
total
expenses
(excluding
any
applicable
12b-1
fees)
as
of
December
31,
2024.
The
first
quintile
represents
the
least
expensive
funds
and
the
fifth
quintile
the
most
expensive
funds.
The
fee
and
expense
data
reported
by
Broadridge
as
of
December
31,
2024
reflected
the
most
recent
fiscal
year-end
data
available
in
Broadridge's
database
at
that
time.

Annual
Report
In
connection
with
their
review
of
fund
management
fees
and
total
expenses,
the
Trustees
also
reviewed
the
costs
of
the
services
provided
and
the
profits
realized
by
the
Advisor
and
its
affiliates
from
their
contractual
relationships
with
the
funds.
This
information
included
trends
in
revenues,
expenses
and
profitability
of
the
Advisor
and
its
affiliates
relating
to
the
investment
management,
investor
servicing
and
distribution
services
provided
to
the
funds,
as
applicable.
In
this
regard,
the
Trustees
also
reviewed
an
analysis
of
the
revenues,
expenses
and
profitability
of
the
Advisor
and
its
affiliates,
allocated
on
a
fund-by-fund
basis,
with
respect
to
(as
applicable)
the
funds'
management,
distribution
and
investor
servicing
contracts.
For
each
fund,
the
analysis
presented
information
about
revenues,
expenses
and
profitability
in
2024
for
each
of
the
applicable
agreements
separately
and
for
the
agreements
taken
together
on
a
combined
basis.
The
Trustees
concluded
that,
at
current
asset
levels,
the
fee
schedules
in
place
for
each
of
the
funds,
including
the
fee
schedule
for
your
fund,
represented
reasonable
compensation
for
the
services
being
provided
and
represented
an
appropriate
sharing
between
fund
shareholders
and
the
Advisor
of
any
economies
of
scale
as
may
exist
in
the
management
of
the
funds
at
that
time.
The
information
examined
by
the
Trustees
in
connection
with
their
annual
contract
review
for
the
funds
included
information
regarding
services
provided
and
fees
charged
by
the
Advisor
and
certain
affiliates
to
other
clients
in
similar
asset
categories,
including
other
1940
Act
funds
advised
by
the
Advisor
but
overseen
by
a
board
of
trustees
other
than
the
Board,
sub-advised
U.S.
mutual
funds,
exchange-traded
funds,
other
U.S.
products
(such
as
collective
investment
trusts,
private
funds,
and
separately
managed
and
institutional
accounts),
non-U.S.
funds,
and
other
non-U.S.
products.
This
information
included,
for
products
that
are
managed
by
the
same
portfolio
team
in
a
similar
asset
category
to
those
of
the
funds,
comparisons
of
the
fees
charged
to
other
clients,
by
category,
with
fees
charged
to
the
funds,
as
well
as
a
detailed
assessment
of
the
differences
in
the
services
provided
to
these
clients
as
compared
to
the
services
provided
to
the
funds.
The
Trustees
observed
that
the
differences
in
fee
rates
between
these
clients
and
the
funds
are
by
no
means
uniform
when
examined
by
individual
asset
classes,
suggesting
that
differences
in
the
pricing
of
investment
management
services
to
these
types
of
clients
may
reflect,
among
other
things,
historical
competitive
forces
operating
in
separate
marketplaces,
the
characteristics
of
different
clients,
the
particulars
of
different
fee
structures,
factors
unique
to
specific
market
segments,
and
the
distinct
risks
and
costs
associated
with
providing
services
to
different
clients.
The
Trustees
considered
the
fact
that
in
many
cases
fee
rates
across
different
asset
classes
are
higher
on
average
for
1940
Act-registered
funds
than
for
other
clients,
and
the
Trustees
also
considered
the
differences
between
the
services
that
the
Advisor
provides
to
the
funds
and
those
that
it
provides
to
its
other
clients.
The
Trustees
did
not
rely
on
these
fee
comparisons
to
any
significant
extent
in
concluding
that
the
management
fees
paid
by
your
fund
are
reasonable.
Investment
performance
The
quality
of
the
investment
process
provided
by
the
Advisor
represented
a
major
factor
in
the
Trustees'
evaluation
of
the
quality
of
services
provided
by
the
Advisor
under
your
fund's
Management
Contracts.
The
Trustees
were
assisted
in
their
review
of
the
Advisor's
investment
process
and
performance
by
the
work
of
the
investment
oversight
committees
of
the
Trustees
and
the
full
Board,
which
meet
on
a
regular
basis
with
individual
portfolio
managers
and
with
senior
investment
management
of
the
Advisor
throughout
the
year.
The
Trustees
concluded
that
the
Advisor
generally
provides
a
high-quality
investment
process
-
based
on
the
experience
and
skills
of
the
individuals
assigned
to
the
management
of
fund
portfolios,
the
resources
made
available
to
them
and
in
general
the
Advisor's
ability
to
attract
and
retain
high-quality
personnel
-
but
also
recognized
that
this
does
not
guarantee
favorable
investment
results
for
every
fund
in
every
time
period.
The
Trustees
considered
that,
in
the
aggregate,
peer-relative
and
benchmark-relative
fund
performance
was
strong
in
2024
against
a
constructive
yet
complex
investing
environment.
The
S&P
500
was
up
25%
in
2024,
but
significant
concentration
of
returns
among
large
cap
and
technology
stocks
and
periods
of
volatility
posed
challenges
in
the
market.
The
Bloomberg
Aggregate
fixed
income
index
was
up
slightly
over
1%
amidst
many
moving
pieces,
with
the
Federal
Reserve
cutting
the
Effective
Federal
Funds
rate
from
5.25%
at
year-end
2023
to
4.25%
at
year-end
2024,
with
three
cuts
in
the
latter
part
of
the
year,
while
also
trying
to
manage
inflation
concerns.
Ten-year
Treasury
yields
ended
2024
at
4.6%
up
from
3.9%
at
year-end
2023.
Corporate
earnings
and
employment
figures
continued
to
generally
show
strength
during
the
year,
while
geopolitical
tensions
were
closely
watched.

Annual
Report
For
the
one-year
period
ended
December
31,
2024,
the
Trustees
noted
that
the
funds,
on
an
asset-weighted
basis,
ranked
in
the
27th
percentile
of
their
peers
as
determined
by
Lipper
Inc.
("Lipper")
and,
on
an
asset-weighted
basis,
outperformed
their
benchmarks
by
3.0%
gross
of
fees
over
the
one-year
period.
The
Committee
also
noted
that
the
funds'
aggregate
performance
over
longer-term
periods
continued
to
be
strong,
with
the
funds,
on
an
asset-weighted
basis,
ranking
in
the
20th,
22nd
and
20th
percentiles
of
their
Lipper
peers
over
the
three-year,
five-year
and
ten-year
periods
ended
December
31,
2024,
respectively.
The
Trustees
further
noted
that
the
funds,
in
the
aggregate,
outperformed
their
benchmarks
on
a
gross
basis
for
each
of
the
three-year,
five-year
and
ten-year
periods.
The
Trustees
also
considered
the
Morningstar
Inc.
ratings
assigned
to
the
funds
and
that
52
funds
were
rated
four
or
five
stars
at
the
end
of
2024,
which
represented
an
increase
of
seven
funds
year-over-year.
The
Trustees
also
considered
that
25
funds
were
five-star
rated
at
the
end
of
2024,
which
was
also
a
year-
over-year
increase
of
seven
funds.
The
Board
noted,
however,
the
disappointing
investment
performance
of
some
funds
for
periods
ended
December
31,
2024
and
considered
information
provided
by
the
Advisor
regarding
the
factors
contributing
to
the
underperformance
and,
where
relevant,
actions
being
taken
to
improve
the
performance
of
these
particular
funds.
The
Trustees
indicated
their
intention
to
continue
to
monitor
the
performance
of
those
funds.
For
purposes
of
the
Trustees'
evaluation
of
the
funds'
investment
performance,
the
Trustees
generally
focus
on
a
competitive
industry
ranking
of
each
fund's
total
net
return
over
a
one-year,
three-year
and
five-year
period.
For
a
number
of
funds
with
relatively
unique
investment
mandates
for
which
the
Advisor
informed
the
Trustees
that
meaningful
competitive
performance
rankings
are
not
considered
to
be
available,
the
Trustees
evaluated
performance
based
on
their
total
gross
and
net
returns
and
comparisons
of
those
returns
to
the
returns
of
selected
investment
benchmarks.
In
the
case
of
your
fund,
the
Trustees
considered
that
its
class
A
share
cumulative
total
return
performance
at
net
asset
value
was
in
the
following
quartiles
of
its
Lipper
peer
group
(Lipper
Large-Cap
Core
Funds)
for
the
one-year,
three-year
and
five-year
periods
ended
December
31,
2024
(the
first
quartile
representing
the
best-performing
funds
and
the
fourth
quartile
the
worst-performing
funds):
For
the
three-year
period
ended
December
31,
2024,
your
fund's
performance
was
in
the
top
decile
of
its
Lipper
peer
group.
Over
the
one-year,
three-year
and
five-year
periods
ended
December
31,
2024,
there
were
675,
614
and
563
funds,
respectively,
in
your
fund's
Lipper
peer
group.
(When
considering
performance
information,
shareholders
should
be
mindful
that
past
performance
is
not
a
guarantee
of
future
results.)
The
Trustees
noted
that
the
Advisor
had
made
internal
promotions
and
other
portfolio
management
assignment
changes
in
2024
to
strengthen
its
investment
teams
providing
services
to
the
funds.
Brokerage
and
soft-dollar
allocations;
distribution
and
investor
servicing
The
Trustees
considered
various
potential
benefits
that
the
Advisor
may
receive
in
connection
with
the
services
it
provides
under
the
management
contract
with
your
fund.
These
include
benefits
related
to
brokerage
allocation
and
the
use
of
soft
dollars,
whereby
a
portion
of
the
commissions
paid
by
a
fund
for
brokerage
may
be
used
to
acquire
research
services
that
are
expected
to
be
useful
to
the
Advisor
in
managing
the
assets
of
the
fund
and
of
other
clients.
Subject
to
policies
approved
by
the
Trustees,
soft
dollars
generated
by
these
means
may
be
used
to
acquire
brokerage
and
research
services
(including
proprietary
executing
broker
research,
third-party
research
and
market
data)
that
enhance
the
Advisor's
investment
capabilities
and
supplement
the
Advisor's
internal
research
efforts.
The
Trustees
indicated
their
continued
intent
to
monitor
regulatory
and
industry
developments
in
this
area
with
the
assistance
of
their
Contract
Committee.
In
addition,
with
the
assistance
of
their
Contract
Committee,
the
Trustees
indicated
their
continued
intent
to
monitor
the
allocation
of
the
funds'
brokerage
in
order
to
ensure
that
the
principle
of
seeking
best
price
and
execution
remains
paramount
in
the
portfolio
trading
process.

Annual
Report
The
Advisor
may
also
receive
benefits
from
payments
that
funds
make
to
the
Advisor
for
distribution
services
and
investor
services.
In
conjunction
with
the
annual
review
of
your
fund's
management
and
sub-advisory
contracts,
the
Trustees
reviewed
your
fund's
investor
servicing
agreement
with
PSERV
and
its
distributor's
contract
and
distribution
plans
with
Franklin
Distributors,
LLC
("Franklin

both
of
which
are

The
Trustees
concluded
that
the
fees
payable
by
the
mutual
funds
to
PSERV
and
Franklin
Distributors
for
such
services
were
fair
and
reasonable
in
relation
to
the
nature
and
quality
of
such
services,
the
fees
paid
by
competitive
funds
and
the
costs
incurred
by
PSERV
and
Franklin
Distributors
in
