PB Bancorp, Inc.



PB Bancorp, Inc. (the
 “Company”) is a Maryland corporation incorporated in 2015 to be the successor to PSB Holdings, Inc. upon completion
of the second-step mutual-to-stock conversion (the “Conversion”) of Putnam Bancorp, MHC (the “MHC”), the
top tier mutual holding company of PSB Holdings, Inc. PSB Holdings, Inc. was the former mid-tier holding company for Putnam Bank
(the “Bank”). Prior to completion of the Conversion, approximately 57% of the shares of common stock of PSB Holdings,
Inc. were owned by the MHC. In conjunction with the Conversion, the MHC and PSB Holdings, Inc. merged into the Company and the
Company became PSB Holdings, Inc.’s successor. The Conversion was completed on January 7, 2016. The Company raised gross
proceeds of $33.7 million by selling 4,215,387 shares of common stock at $8.00 per share. Also, an additional 317,287 shares were
purchased by the Bank’s Employee Stock Ownership Plan with the proceeds of a loan from the Company. Concurrent with the completion
of the stock offering, each share of PSB Holdings, Inc. stock owned by public stockholders (stockholders other than the MHC) was
exchanged for 1.1907 shares of Company common stock.



PB Bancorp, Inc. also
owns investment securities valued at $5.2 million as of June 30, 2019. We have not engaged in any significant business activity
other than owning the common stock of Putnam Bank, providing the loan to allow the purchase of shares of common stock by the Employee
Stock Ownership Plan and investing in marketable securities. Our executive office is located at 40 Main Street, Putnam, Connecticut
06260, and our telephone number is (860) 928-6501.



Putnam Bank



Putnam Bank was founded
in 1862 as a state-chartered mutual savings bank. In 2014, the Bank converted from a federally-chartered savings bank to a Connecticut-chartered
bank that is a member of the Federal Reserve System. The Bank is headquartered at 40 Main Street in Putnam, Connecticut and conducts
substantially all of its business from eight full-service banking offices and one loan origination center. Putnam Bank is a wholly-owned
subsidiary of the Company. In addition, the Bank maintains a “Special Needs Limited Branch” and a limited services
mobile office. The telephone number at the Bank’s main office is (860) 928-6501.



Available Information



PB Bancorp, Inc. is
a public company, and files interim, quarterly and annual reports with the Securities and Exchange Commission. These respective
reports are on file and a matter of public record with the Securities and Exchange Commission and may be obtained on the Securities
and Exchange Commission’s website (http://www.sec.gov).



Our website address
is www.putnambank.com. Information on our website should not be considered a part of this annual report.



General



Our principal
business consists of attracting deposits from the general public in the communities where our offices are located, and
investing those deposits, together with funds generated from operations, primarily in loans secured by real estate, including
one-to-four family residential mortgage loans and commercial real estate loans (including multi-family real estate
loans).  To a lesser extent, we originate commercial loans, residential construction loans and consumer loans.  We
also invest in investment securities.

Market Area



Our market area has
a relatively stable population and household base.  We currently operate out of eight offices, which are located in Windham
County and New London County, Connecticut.  Windham County is located in the Northeastern corner of Connecticut and borders
both Massachusetts (to the north) and Rhode Island (to the east).  New London County is to the south of Windham County, located
in the Southeastern corner of Connecticut.  Putnam is approximately 45 miles from Hartford, Connecticut, 30 miles from Providence,
Rhode Island, and 65 miles from Boston, Massachusetts.



According to S&P
Global Market Intelligence, from 2014 to 2019, the population of Windham County decreased by 0.6%, and New London County’s
population decreased 2.3%.  At the same time, the population of the state of Connecticut decreased by 0.3%, while the United
States’ population increased by 3.8%.  During the same period, the number of households declined in both Windham County
and New London County (by 0.3% and 1.7%, respectively) and Connecticut showed a slight decline (0.1%) as well.  Comparatively,
the number of households increased on a nationwide basis, by 4.0%.  In 2019, per capita income and median household income
for Windham County equaled $33,235 and $66,793, respectively.  In the same year, per capita income and median household income
for New London County equaled $42,459 and $76,305, respectively.  These compare to 2019 per capita income measures for the
state of Connecticut and the United States of $45,112 and $34,902, respectively, and 2019 median household income measures for
the state of Connecticut and the United States of $78,970 and $63,174, respectively.



Windham County has
a diversified mix of industry groups and employment sectors, including education/healthcare/social services, services and wholesale/retail
trade.  According to S&P Global Market Intelligence, these three sectors comprise approximately 66% of the employment
base in Windham County.  The same three sectors comprised approximately 66% of the employment base in New London County.



June 2019 unemployment
rates for Windham County at 4.4% and Connecticut at 3.9% were above the national unemployment rate of 3.8%, while New London County’s
unemployment rate of 3.8% matched the national rate.  Notably, the June 2019 unemployment rates for the United States, Connecticut,
Windham County, and New London County have all decreased relative to their June 2018 unemployment rates of 4.2%, 4.4%, 4.8% and
4.2%, respectively.  Our primary market area for deposits includes the communities in which we maintain our main office and
our branch office locations.  Our primary lending area is broader than our primary deposit market area and includes all of
Windham County, and parts of the adjacent Connecticut Counties of New London and Tolland, as well as the Rhode Island and Massachusetts
communities adjacent to Windham County.



Competition



We face intense competition
within our market area for deposits and loans. The Town of Putnam and the surrounding area have a high concentration of financial
institutions, including large commercial banks, community banks and credit unions. Several large holding companies operate banks
in our market area. Many of them are significantly larger than us and, therefore, have greater resources.  Additionally, some
of our competitors offer products and services that we currently do not offer, such as trust services and private banking. We face
additional competition for deposits from money market funds, brokerage firms, insurance companies, mutual funds and other corporate
and government securities.



As of June 30, 2018,
based on the Federal Deposit Insurance Corporation’s annual Summary of Deposits Report (the most current data available),
our market share of Federal Deposit Insurance Corporation-insured deposits represented 18.9% of deposits in Windham County, giving
us the second largest market share out of ten financial institutions with offices in that county as of that date, and 1.4% of deposits
in New London County, giving us the 11th largest market share out of 15 financial institutions with offices in that
county as of that date.



Lending Activities



Historically, our principal
lending activity has been the origination of first mortgage loans for the purchase or refinancing of one-to-four family residential
real estate, and we have recently increased our origination of commercial real estate loans. Historically, we have sold the majority
of longer-term, fixed-rate loans (other than bi-weekly loans) in the secondary market. However, the additional capital raised in
the offering has permitted us to retain longer term, fixed-rate loans in our portfolio.

At June 30, 2019, the
total amount of loans that had fixed interest rates was $204.1 million, and the total amount of loans that had floating or adjustable
interest rates was $175.8 million.



Residential Real
Estate Loans. Our primary residential lending activity consists of the origination of one-to-four family residential real
estate loans that are primarily secured by properties located in Windham and New London Counties, Connecticut. At June 30, 2019,
$221.5 million, or 58.3% of our loan portfolio, consisted of one-to-four family residential real estate loans. At June 30,
2019, our residential real estate loans included $8.1 million of second mortgages and $7.0 million of home equity lines of credit.
Generally, one-to-four family residential real estate loans are originated in amounts up to 80% of the lesser of the appraised
value or purchase price of the property, with private mortgage insurance required on loans with a loan-to-value ratio in excess
of 80%. We will not make loans with a loan-to-value ratio in excess of 100% for one-to-four family residential real estate loans.
Fixed rate real estate loans generally are originated for terms of 10 to 30 years. Generally, all fixed rate residential real estate
loans are underwritten according to Fannie Mae policies and procedures. There were no residential real estate loans purchased during
the fiscal year ended June 30, 2019.



At June 30, 2019, $56.6
million, or 25.6%, of our residential real estate loans were bi-weekly real estate loans. Bi-weekly real estate loans are loans
that require payments to be made every two weeks, thus shortening the duration of the loan. The borrower is required to maintain
a deposit account with us for automatic withdrawal of the mortgage payment.



Historically, we have
sold the majority of longer-term, fixed-rate loans (other than bi-weekly loans) in the secondary market. However, the additional
capital raised in the offering has permitted us to retain longer term, fixed-rate loans in our portfolio. We originated $14.6 million
of fixed rate one-to-four family residential loans during the year ended June 30, 2019, of which $1.5 million were sold in the
secondary market.



We also offer adjustable
rate mortgage loans for one-to-four family properties, with an interest rate based on the one-year Constant Maturity Treasury Bill
Index, which adjusts annually from the outset of the loan or which adjusts annually after a three-, five-, seven-, or ten-year
initial fixed rate period. We originated $7.9 million of adjustable rate one-to-four family residential loans during the year ended
June 30, 2019, none of which were sold in the secondary market. Our adjustable rate mortgage loans generally provide for maximum
rate adjustments of 100 basis points per adjustment, with a lifetime maximum adjustment up to 6% above the initial rate, regardless
of the initial rate. Our adjustable rate real estate loans amortize over terms of up to 30 years.



Adjustable rate real
estate loans decrease the risk associated with changes in market interest rates by periodically repricing, but involve other risks
because, as interest rates increase, the monthly or bi-weekly payments by the borrower increase, thus increasing the potential
for default by the borrower. At the same time, the value of the underlying collateral may be adversely affected by higher interest
rates. Upward adjustment of the contractual interest rate is also limited by the maximum periodic and lifetime interest rate adjustments
permitted by our loan documents and, therefore, the effectiveness of adjustable rate real estate loans may be limited during periods
of rapidly rising interest rates. At June 30, 2019, $88.8 million, or 40.1%, of our one-to-four family residential loans had adjustable
rates of interest.

In an effort to provide
financing for moderate income home buyers, we offer Veterans Administration (“VA”), Connecticut Housing Finance Authority
(“CHFA”) and Rural Development (“RD”) loans. These programs offer residential real estate loans to qualified
individuals. These loans are offered with fixed rates of interest and terms of up to 30 years. Such loans are secured by one-to-four
family residential properties. All of these loans are originated using agency underwriting guidelines. RD, VA and CHFA loans are
closed in the name of Putnam Bank and are immediately sold on a servicing-released basis. All such loans are originated in amounts
of up to 100% of the lower of the property’s appraised value or the sale price.



All residential real
estate loans that we originate include “due-on-sale” clauses, which give us the right to declare a loan immediately
due and payable if, among other things, the borrower sells or otherwise disposes of the real property subject to the mortgage and
the loan is not repaid. Regulations limit the amount that a savings association may lend relative to the appraised value of the
real estate securing the loan, as determined by an appraisal of the property at the time the loan is originated. All borrowers
are required to obtain title insurance. We also require homeowner’s insurance and fire and casualty insurance and, where
circumstances warrant, flood insurance, on properties securing real estate loans. At June 30, 2019, our largest residential real
estate loan had a principal balance of $1.1 million and was secured by a one-to-four family residence located in Massachusetts.
At June 30, 2019, this loan was performing in accordance with its original terms.



At June 30, 2019, second
mortgages and home equity lines of credit totaled $15.1 million, or 6.8% of our residential real estate loans and 4.0% of total
loans. Additionally, at June 30, 2019, the unadvanced amounts of home equity lines of credit totaled $10.8 million. The underwriting
standards utilized for second mortgages and home equity lines of credit include a determination of the applicant’s credit
history, an assessment of the applicant’s ability to meet existing obligations and payments on the proposed loan and the
value of the collateral securing the loan. Second mortgages are offered with fixed rates of interest and with terms of up to 15
years. The loan-to-value ratio for a home equity loan is generally limited to 80%. However, we offer special programs to borrowers,
who satisfy certain underwriting criteria, with loan-to-value ratios of up to 100%. Our home equity lines of credit have adjustable
rates of interest which are indexed to the prime rate, as reported in The Wall Street Journal.



Commercial Real
Estate Loans.We originate commercial real estate loans, including multi-family real estate loans. These loans are generally
secured by one-to-four family non-owner occupied investment properties, multi-family real estate of 20 units or less, small commercial
owner and non-owner occupied properties, hotels, non-owner occupied condominiums and commercial vacant land.  The security
for these loans is primarily located in our primary market area. At June 30, 2019, commercial mortgage loans totaled $145.7 million,
or 38.4% of total loans. Our commercial real estate underwriting policies provide that such real estate loans may be made in amounts
of up to 80% of the appraised value of the property provided such loan complies with our current loans-to-one-borrower limit, which
at June 30, 2019 was $11.1 million. Our commercial real estate loans may be made with terms of up to five years with 20-year amortization
schedules and are offered with interest rates that are fixed or that adjust periodically and are generally indexed to the prime
rate as reported in The Wall Street Journalor to Federal Home Loan Bank advance rates. In reaching a decision on whether
to make a commercial real estate loan, we consider the net operating income of the property, the borrower’s expertise and
credit history, and the profitability of the value of the underlying property. In addition, with respect to commercial real estate
rental properties, we will also consider the term of the lease and the quality of the tenants. We generally require that the properties
securing these real estate loans have debt service coverage ratios (the ratio of earnings before debt service to debt service)
of at least 1.25x. Environmental surveys are generally required for commercial real estate loans. Generally, multi-family and commercial
real estate loans made to corporations, partnerships and other business entities require personal guarantees by the principals.



A commercial
borrower’s financial information is monitored on an ongoing basis by requiring periodic financial statement updates,
payment history reviews and periodic face-to-face meetings with the borrower. We require commercial borrowers to provide
annually updated financial statements and federal tax returns. These requirements also apply to all guarantors on commercial
loans. We also require borrowers with rental investment property to provide an annual report of income and expenses for the
property, including a tenant list and copies of leases, as applicable. The largest commercial real estate loans in our
portfolio at June 30, 2019 were loans totaling $8.5 million, secured by a hotel located in Connecticut. These loans consisted
of $7.4 million outstanding, with an unadvanced portion of $1.1 million as of June 30, 2019. At June 30, 2019, these loans
were performing in accordance with its original terms.

Loans secured by commercial
real estate, including multi-family properties, generally involve larger principal amounts and a greater degree of risk than one-to-four
family residential real estate loans. Because payments on loans secured by commercial real estate, including multi-family properties,
are often dependent on successful operation or management of the properties, repayment of such loans may be affected by adverse
conditions in the real estate market or the economy.



Commercial Loans.
At June 30, 2019, we had $10.3 million in commercial business loans, which amounted to 2.7% of total loans. We make such commercial
loans primarily in our market area to a variety of professionals, sole proprietorships and small businesses. Commercial lending
products include term loans and revolving lines of credit. Such loans are generally used for longer-term working capital purposes
such as purchasing equipment or furniture. Commercial loans are made with either adjustable or fixed rates of interest. Variable
rates are based on the prime rate, as published in The Wall Street Journal,plus a margin. Fixed rate commercial loans are
set at a margin above the comparable Federal Home Loan Bank advance rate.



When making commercial
loans, we consider the financial condition of the borrower, our lending history with the borrower, the debt service capabilities
of the borrower, the projected cash flows of the business and the value of the collateral. Commercial loans are generally secured
by a variety of collateral, primarily accounts receivable, inventory and equipment, and are supported by personal guarantees. Depending
on the collateral used to secure the loans, commercial loans are made in amounts of up to 75% of the value of the collateral securing
the loan. We generally do not make unsecured commercial loans.



Commercial loans generally
have greater credit risk than residential real estate loans. Unlike residential real estate loans, which generally are made on
the basis of the borrower’s ability to make repayment from his or her employment or other income, and which are secured by
real property whose value tends to be more easily ascertainable, commercial loans generally are made on the basis of the borrower’s
ability to repay the loan from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment
of commercial loans may depend substantially on the success of the business itself. Further, any collateral securing the loans
may depreciate over time, may be difficult to appraise and may fluctuate in value. We seek to minimize these risks through our
underwriting standards. At June 30, 2019, our largest commercial loan was a $943,000 loan secured by business assets located in
our primary market area. This loan was performing according to its original terms at June 30, 2019.



Origination,
Purchase, Sale and Servicing of Loans. Lending activities are conducted primarily by our loan personnel operating at our
eight branch offices and one loan origination center. All loans originated by us are underwritten pursuant to our policies and
procedures. We originate both adjustable rate and fixed rate loans. Our ability to originate fixed or adjustable rate loans is
dependent upon the relative customer demand for such loans, which is affected by current and expected future levels of market interest
rates. There were no loans purchased during the fiscal year ended June 30, 2019. The Bank performs its own underwriting analysis
before purchasing a loan and, therefore, believes there should not be a greater risk of default on these obligations compared to
loans the Bank originates itself. However, generally in a purchased loan, the Bank does not service the loan and thus is subject
to the policies and practices of the originating lender with regard to pursuing collections and foreclosure proceedings.



Historically, we have
sold the majority of longer-term, fixed-rate loans (other than bi-weekly loans) in the secondary market. However, the additional
capital raised in the offering has permitted us to retain longer term, fixed-rate loans in our portfolio. The one-to-four family
loans that we currently originate for sale include mortgage loans which conform to the underwriting standards specified by Fannie
Mae. We also sell all mortgage loans insured by CHFA, VA and Rural Development. Generally, we sell our loans without recourse.
We retain the servicing rights on the mortgage loans sold to Fannie Mae, but sell all CHFA, VA, and Rural Development loans on
a servicing-released basis.

At June 30,
2019, Putnam Bank was servicing loans in the amount of $20.0 million. Loan servicing includes collecting and remitting loan
payments, accounting for principal and interest, contacting delinquent mortgagors, supervising foreclosures and property
dispositions in the event of unremedied defaults, making certain insurance and tax payments on behalf of the borrowers and
generally administering the loans.



During the fiscal year
ended June 30, 2019, we originated $22.5 million of one-to-four family loans, of which we retained $21.0 million. We recognize
at the time of sale, the cash gain or loss on the sale of the loans based on the difference between the net cash proceeds received
and the carrying value of the loans sold.



Loan Approval
Procedures and Authority. The board of directors establishes the lending policies and loan approval limits of Putnam Bank.
Loan officers generally have the authority to originate loans up to amounts established for each lending officer. Loans in amounts
above the individual authorized limits require the approval of Putnam Bank’s Credit Committee. The Credit Committee is authorized
to approve all loans-to-one borrower relationships in amounts up to $750,000. Putnam Bank’s Board of Directors must approve
all loans and relationships that are $750,000 or greater.



The board of directors
annually approves independent appraisers used by Putnam Bank. For larger loans, we may require an environmental site assessment
to be performed by an independent professional for all non-residential real estate loans. It is our policy to require hazard insurance
on all real estate loans.



Loan Origination
Fees and Other Income. In addition to interest earned on loans, Putnam Bank receives loan origination fees. Such fees and
costs vary with the volume and type of loans and commitments made and purchased, principal repayments, and competitive conditions
in the mortgage markets, which in turn respond to the demand and availability of money.



Loans to One
Borrower. The maximum amount that we may lend to one borrower and the borrower’s related entities is generally limited,
by regulation, to 15% of our stated capital and reserves. At June 30, 2019, our regulatory limit on loans to one borrower was $11.1
million. At that date, the largest aggregate amount loaned by Putnam Bank to one borrower was $8.5 million, consisting of commercial
real estate loans. These loans consisted of $7.4 million outstanding, with an unadvanced portion of $1.1 million as of June 30,
2019. The loans comprising this lending relationship were performing in accordance with their original terms as of June 30, 2019.



Delinquencies and Classified Assets



Collection ProceduresA computer-generated delinquency notice is mailed monthly to all delinquent borrowers, advising them of the amount of their
delinquency. When a loan becomes 60 days delinquent, Putnam Bank sends a letter advising the borrower of the delinquency. The borrower
is given 30 days to pay the delinquent payments or to contact Putnam Bank to make arrangements to bring the loan current over a
longer period of time. If the borrower fails to bring the loan current in 30 days or to make arrangements to cure the delinquency
over a longer period of time, the matter is referred to legal counsel and foreclosure proceedings are started. We may consider
forbearance in cases of a temporary loss of income if a plan is presented by the borrower to cure the delinquency in a reasonable
period of time after his or her income resumes.



Loans Past Due
and Non-Performing Assets.  Loans are reviewed on a regular basis.  Management determines that a loan
is impaired or non-performing when it is probable at least a portion of the loan will not be collected in accordance with the original
terms due to a deterioration in the financial condition of the borrower or the value of the underlying collateral, if the loan
is collateral dependent.  When a loan is determined to be impaired, the measurement of the loan in the allowance for
loan losses is based on present value of expected future cash flows, except that all collateral-dependent loans are measured for
impairment based on the fair value of the collateral. Non-accrual loans are loans in which collectability is questionable and therefore
interest on such loans will no longer be recognized on an accrual basis. All loans that become 90 days or more delinquent
are placed on non-accrual status unless the loan is well secured and in the process of collection. When loans are placed on non-accrual
status, unpaid accrued interest is fully reversed, and further income is recognized only to the extent received on a cash basis
or cost recovery method.  At June 30, 2019, we had non-performing loans of $4.2 million and a ratio of non-performing
loans to total loans of 1.1%.





8







Real estate acquired
as a result of foreclosure or by deed in lieu of foreclosure is classified as other real estate owned (“OREO”) until
such time as it is sold.  When real estate is acquired through foreclosure or by deed in lieu of foreclosure, it is recorded
at its fair value, less estimated costs of disposal.  If the value of the property is less than the loan, less any related
specific loan loss provisions, the difference is charged against the allowance for loan losses.  Any subsequent write-down
of OREO is charged against earnings.  At June 30, 2019, we had OREO of $1.3 million. Other real estate owned is included
in non-performing assets.



A loan is classified
as a troubled debt restructuring if, for economic or legal reasons related to the borrower’s financial difficulties, we grant
a concession to the borrower that we would not otherwise consider. This usually includes a modification of loan terms, such as
a reduction of the interest rate to below market terms, capitalizing past due interest or extending the maturity date and possibly
a partial forgiveness of debt. Interest income on restructured loans is accrued after the borrower demonstrates the ability to
pay under the restructured terms through a sustained period of repayment performance, which is generally six consecutive months.



Non-Performing
Assets. The table below sets forth the amounts and categories of our non-performing assets at the dates indicated. A loan
classified in the table below as “non-accrual” does not necessarily mean that such loan is or has been delinquent.
Once a loan is delinquent 90 days or more or the borrower or collateral securing the loan experiences an event that makes collectability
doubtful, the loan is placed on “non-accrual” status. Our policies require six consecutive months of contractual payments
in order for the loan to be removed from non-accrual status.

Management is focused
on working with borrowers and guarantors to resolve non-performing loans by restructuring or liquidating assets when prudent. We
review the strength of the guarantors; require face to face discussions and offer restructuring suggestions that provide the borrowers
with short-term relief and exit strategies. Overall, we expect to see improvement as solutions are identified and executed. We
obtain a current appraisal on all real estate secured loans that are 180 days or more past due if the appraisal in our file is
older than one year. If the determination is made that there is the potential for collateral shortfall, an allocated reserve will
be assigned to the loan for the expected deficiency. It is our policy to charge off or write down loans or other assets when, in
the opinion of the Credit Committee and external loan review, the ultimate amount recoverable is less than the book value, or the
collection of the amount is expected to be unduly prolonged. The level of non-performing assets is expected to fluctuate in response
to changing economic and market conditions, and the relative sizes of the respective loan portfolios, along with management’s
degree of success in resolving problem assets. Management takes a proactive approach with respect to the identification and resolution
of problem loans

Classified Assets.
Applicable banking regulations and our internal policies require that management utilize an internal asset classification system
to monitor and evaluate the credit risk inherent in its loan portfolio. We currently classify problem and potential problem assets
as “substandard”, “doubtful”, “loss” or “special mention.” An asset is considered
 “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the
collateral pledged, if any. “Substandard” assets include those characterized by the distinct possibility that the institution
will sustain some loss if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses
inherent in those classified “substandard” with the added characteristic that the weaknesses present make collection
or liquidation in full, on the basis of currently existing facts, conditions, and values, questionable, and there is a high probability
of loss. Assets classified as “loss” are those considered uncollectible and of such little value that their continuance
as loans is not warranted. In addition, assets that do not currently expose us to sufficient risk to warrant classification in
one of the aforementioned categories but possess credit deficiencies or potential weaknesses are required to be designated “special
mention.”



An insured institution
is required to establish general allowances for loan losses in an amount deemed prudent by management for loans classified substandard
or doubtful, as well as for other potential problem loans. General allowances represent loss allowances which have been established
to recognize the inherent losses associated with lending activities, but which, unlike specific allowances, have not been allocated
to particular problem assets. When an insured institution classifies problem assets as “loss”, it is required either
to establish a specific allowance for losses equal to 100% of the amount of the asset so classified or to charge off such amount.
Our determination as to the classification of its assets and the amount of its valuation allowances is subject to review by our
banking regulators, who can order the establishment of additional general or specific loss allowances.





11







On the basis of management’s
review of our assets, at June 30, 2019, we classified $5.9 million of our loans as substandard and no loans as doubtful. Of these
loans, $3.8 million were considered non-performing and included in the table of non-performing assets. At June 30, 2019, $1.6 million
of our loans were designated as special mention, and none of our assets were classified as loss.





The loan portfolio
is reviewed on a regular basis to determine whether any loans require classification in accordance with applicable regulations.
Not all classified assets constitute non-performing assets.



Allowance for Loan Losses



Our allowance for loan
losses is maintained at a level necessary to absorb loan losses that are both probable and reasonably estimable. Management, in
determining the allowance for loan losses, considers the losses inherent in our loan portfolio and changes in the nature and volume
of loan activities, along with the general economic and real estate market conditions. We identify and establish specific loss
allowances on impaired loans, establish general valuation allowances on the remainder of our loan portfolio and establish an unallocated
portion to reflect losses resulting from the inherent imprecision involved in the loss analysis process. Once a loan becomes delinquent
or otherwise identified as impaired, we may establish a specific loan loss allowance based on a review of among other things, expected
cash flows, delinquency status, size of loans, type and market value of collateral and financial condition of the borrowers. General
loan loss allowances are based upon a combination of factors including, but not limited to, actual loan loss experience, composition
of the loan portfolio, current economic conditions and delinquency trends. The allowance is increased through provisions charged
against current earnings and recoveries of previously charged-off loans. The portions of loans that are determined to be uncollectible
are charged against the allowance. While management uses available information to recognize probable and reasonably estimable loan
losses, future loss provisions may be necessary based on changing economic conditions. The allowance for loan losses as of June
30, 2019 was maintained at a level that represents management’s best estimate of losses inherent in the loan portfolio, and
such losses were both probable and reasonably estimable.



In addition, the Federal
Reserve Board and the Connecticut Department of Banking, as an integral part of their examination process, periodically review
our allowance for loan losses. These agencies may require that we recognize additions to the allowance based on their judgment
of information available to them at the time of examination.

Each quarter, management
evaluates the allowance for loan losses based on several factors, some of which are not loan specific but are reflective of the
inherent losses in the loan portfolio. This process includes, but is not limited to, a periodic review of loan collectability in
light of historical experience, the nature and volume of loan activity, conditions that may affect the ability of the borrower
to repay, underlying value of collateral, if applicable, and economic conditions in our immediate market area. First, we group
loans by delinquency status. All loans 90 days or more delinquent are generally evaluated individually along with other impaired
loans, based primarily on the present value of expected future cash flows or the value of the collateral securing the loan. Specific
loss allowances are established as required by this analysis. All loans which are not individually evaluated are segregated by
type or loan grade and a loss allowance is established by using loss experience data and management’s judgment concerning
other matters it considers significant. The allowance is allocated to each category of loan based on the results of the above analysis.
Differences between the allocated balances and recorded allowances are reflected as unallocated to absorb losses resulting from
the inherent imprecision involved in the loss analysis process.



This analysis process
is inherently subjective, as it requires us to make estimates that are susceptible to revisions as more information becomes available.
Although we believe that we have established the allowance at levels to absorb probable and estimable losses, future additions
may be necessary if economic or other conditions in the future differ from the current environment. Additionally, our regulators,
as a part of their examination process, periodically review our allowance for loan losses and may require us to recognize additions
to the allowance based on their judgements at the time of their examination.



Investment Activities



Putnam Bank’s
Executive Committee is responsible for implementing Putnam Bank’s Investment Policy. The Investment Policy is reviewed annually
and any changes to the policy are recommended to, and subject to, the approval of our board of directors. The Executive Committee
is comprised of our Chairman, President, Executive Vice President and one rotating director. Authority to make investments under
the Investment Policy guidelines is delegated by the Executive Committee to appropriate officers. While general investment strategies
are developed and authorized by the Asset/Liability Committee, the execution of specific actions rests with the Chief Executive
Officer or Executive Vice President who may act jointly or severally as Putnam Bank’s Investment Officer. The Investment
Officer is responsible for ensuring that the guidelines and requirements included in the Investment Policy are followed and that
all securities are considered prudent for investment. The Investment Officer is authorized to execute investment transactions (purchases
and sales) up to $5 million per transaction without the prior approval of the Executive Committee and within the scope of the established
Investment Policy. Each transaction in excess of established limits must receive prior approval of the Executive Committee.



In addition, Putnam
Bank utilizes the services of an independent investment advisor to assist in managing the investment portfolio. The investment
advisor is responsible for maintaining current information regarding securities dealers with whom they are conducting business
on our behalf. A list of appropriate dealers is provided annually to the board of directors for approval prior to execution of
trades. The investment advisor, through its assigned portfolio manager, must contact our President or Treasurer to review all investment
recommendations and transactions and receive approval from the President or Treasurer prior to execution of any transaction that
might be transacted on our behalf. Upon receipt of approval, the investment advisor, or its assigned portfolio manager, is authorized
to conduct all investment business on our behalf.



Our Investment Policy
requires that all securities transactions be conducted in a safe and sound manner. Investment decisions must be based upon a thorough
analysis of each security instrument to determine its quality, inherent risks, fit within our overall asset/liability management
objectives, effect on our risk-based capital measurement and prospects for yield and/or appreciation.



The investment policy
is consistent with our overall business and asset/liability management strategy, which focuses on sustaining adequate levels of
core earnings. During the fiscal year ended June 30, 2019, we recognized $33,000 in other-than-temporary write-downs on non-agency
mortgage-backed securities.

U.S. Government
and government-sponsored securities. At June 30, 2019, our U.S. Government and government-sponsored securities portfolio
classified as available-for-sale totaled $2.2 million, or 2.2% of total securities. At June 30, 2019, our U.S. Government and government-sponsored
securities portfolio classified as held-to-maturity totaled $9.4 million, or 9.1% of total securities. While U.S. Government and
government-sponsored securities generally provide lower yields than other investments in our securities investment portfolio, we
maintain these investments, to the extent appropriate, for liquidity purposes and as collateral for borrowings.



Corporate Bonds. At June 30, 2019, we had three investments in corporate single-issuer trust preferred securities with a total book value
of $4.0 million and total fair value of $3.7 million, or 3.6% of total securities, all of which were classified as available-for-sale.
The single-issuer trust preferred investments are evaluated for other-than-temporary impairment by performing a present value of
cash flows each quarter. None of the issuers have deferred interest payments or announced the intention to defer interest payments.
We believe the decline in fair value is related to the spread over three-month LIBOR, on which the quarterly interest payments
are based, as the spread over LIBOR being received is significantly lower than current market spreads. Management concluded the
impairment of these investments was considered temporary and asserts that we do not have the intent to sell these investments and
that it is more likely than not it will not have to sell the investments before recovery of their cost basis which may be at maturity.



Although corporate
bonds may offer higher yields than U.S. Treasury or agency securities of comparable duration, corporate bonds also have a higher
risk of default due to possible adverse changes in the creditworthiness of the issuer. In order to mitigate this risk, our investment
policy requires that corporate debt obligations be rated investment grade or better by a nationally recognized rating agency. If
the bond rating goes below investment grade, then the investment is placed on an investment “watch report” and is monitored
by our Investment Officer. The investment is then reviewed quarterly by our board of directors where a determination is made to
hold or dispose of the investment.



Mortgage-Backed
Securities.We purchase mortgage-backed securities insured or guaranteed by Fannie Mae, Freddie Mac and Ginnie Mae. We
invest in mortgage-backed securities to achieve positive interest rate spreads with minimal administrative expense, and lower our
credit risk as a result of the guarantees provided by Freddie Mac, Fannie Mae and Ginnie Mae. We also invest in collateralized
mortgage obligations (CMOs or non-agency mortgage-backed securities), also insured or issued by Freddie Mac, Fannie Mae and Ginnie
Mae, or private issuers such as Washington Mutual and Countrywide Home Loans. All private issuer CMOs were rated AAA at time of
purchase.



Mortgage-backed securities
are created by the pooling of mortgages and the issuance of a security with an interest rate that is less than the interest rates
on the underlying mortgages. Mortgage-backed securities typically represent a participation interest in a pool of single-family
or multi-family mortgages, although we focus our investments on mortgage-backed securities backed by one-to-four family mortgages.
The issuers of such securities (generally U.S. government agencies and government-sponsored enterprises, including Fannie
Mae, Freddie Mac and Ginnie Mae) pool and resell the participation interests in the form of securities to investors such as Putnam
Bank, and guarantee the payment of principal and interest to investors. Mortgage-backed securities generally yield less than the
loans that underlie such securities because of the cost of payment guarantees and credit enhancements. However, mortgage-backed
securities are usually more liquid than individual mortgage loans and may be used to collateralize our specific liabilities and
obligations.



CMOs are a type of
mortgage-backed security issued by a special purpose entity that aggregates pools of mortgage-backed securities and creates different
classes of CMO securities with varying maturities and amortization schedules as well as a residual interest, with each class, or
 “tranche,” possessing different risk characteristics. A particular tranche of CMOs may, therefore, carry prepayment
risk that differs from that of both the underlying collateral and other tranches. We purchase CMO tranches in an attempt to moderate
reinvestment risk associated with mortgage-backed securities resulting from unexpected prepayment activities.





16







At June 30,
2019, mortgage-backed securities and CMOs classified as available-for-sale totaled $23.0 million, or 22.5% of total
securities. At June 30, 2019, mortgage-backed securities and CMOs classified as held-to-maturity totaled $53.7 million, or
52.4% of total securities. At June 30, 2019, 59.6% of the mortgage-backed securities were backed by adjustable rate loans and
40.4% were backed by fixed rate mortgage loans. The mortgage-backed securities portfolio had a weighted average yield of
2.96% at June 30, 2019. Investments in mortgage-backed securities involve a risk that actual prepayments may differ from
estimated prepayments over the life of the security, which may require adjustments to the amortization of any premium or
accretion of any discount relating to such instruments thereby changing the net yield on such securities. There is also
reinvestment risk associated with the cash flows from such securities or if such securities are redeemed by the issuer. In
addition, the market value of such securities may be adversely affected by changes in interest rates.



State agency
and municipal obligations. At June 30, 2019, our state agency and municipal obligations portfolio classified as held-to-maturity
totaled $440,000, or 0.4% of total securities.



Other Debt securities. At June 30, 2019, other debt securities portfolio totaled $10.0 million, or 9.7% of total securities, all of which
were classified as available-for-sale. At June 30, 2019, the portfolio consisted of auction-rate trust preferred securities (“ARP”).
Auction-rate trust preferred securities are a floating rate preferred stock, on which the dividend rate generally resets every
90 days based on an auction process to reflect the yield demand for the instruments by potential purchasers. At June 30, 2019,
our investments in auction-rate trust preferred securities consisted of investments in three corporate issuers. We originally purchased
these securities because they represented highly liquid, tax-preferred investments secured, in most cases, by preferred stock issued
or guaranteed by high quality, investment grade companies, generally other financial institutions (“collateral preferred
shares”). The ARP shares, or certificates, we purchased are Class A certificates, which, among other rights, entitles the
holder to priority claim on dividends paid into the trust holding the preferred shares.



In most cases, the
trusts which issued the ARP certificates own various callable preferred shares of stock by a single entity. In addition to the
call dates for redemption established by the collateral preferred shares, each trust has a maturity date upon which the trust itself
will terminate. The value of the remaining collateral preferred shares is not guaranteed, and may be more or less than the stated
par value of the collateral preferred shares, and is dependent on the market value of those collateral preferred shares on the
date of the trust’s maturity.



The certificates issued
by the trusts previously traded in an active, open auction market, with each individual trust establishing the frequency of its
auctions, typically every 90 days (the “reset date”). The results of an auction would be the exchange of certificates,
at par, between participants entering or exiting the market, and resetting of the yield to be earned by holders of the Class A
certificates as well as the holders of other classes of trust certificates.



Beginning in February
2008, auctions for these securities began to fail when investors declined to bid on the securities. Five of the largest investment
banks that made a market in these securities (Merrill Lynch, Citigroup, USB, AG and Morgan Stanley) declined to act as bidders
of last resort, as they had in the past. The auction failures did not result in the loss of any principal value to the certificate
holders, but prevented many sellers from exiting, or redeeming, their certificates at the reset date. These unsuccessful sellers
were required to continue to hold the certificates until the next scheduled reset date. To compensate these unsuccessful sellers,
the failed auctions triggered a penalty-rate feature which provided that owners of the Class A certificates were entitled to a
higher portion of the dividends, and thus a higher yield, on the Class A certificates.



During this time, we
attempted to divest the ARPs, but were prevented from doing so due to the continued failure of the auction market. We continued
to carry our investments at par value, despite the increased liquidity risk, because the credit strength of the issuers of the
collateral preferred shares remained high, and the yield remained above-market.



The turmoil in the
financial markets caused the value of the underlying collateral preferred shares to decline dramatically. Market values for the
ARPs from Merrill Lynch, our safekeeping agent, also declined, and we recorded a temporary impairment adjustment to the carrying
value of the ARPs, which are classified as available-for-sale. A temporary impairment reduces the carrying value of the investment
security with an offsetting reduction in our capital accounts.





17







We determine the fair
value of the ARPs classified as Level 3 using the quoted market values of the underlying collateral preferred shares, adjusted
for the higher yield we earned through the Class A certificates compared with the nominal rate available to a direct owner of the
collateral preferred shares. We have not changed this pricing methodology.



As of June 30, 2019,
there was an unrealized loss of $24,000, or 0.8% on these securities. We have the ability and intent to hold these securities for
the time necessary to collect the expected cash flows.

to a tax-equivalent basis. Certain mortgage-backed securities have interest rates that are adjustable and will reprice annually
within the various maturity ranges. These repricing schedules are not reflected in the table below. At June 30, 2019, mortgage-backed
securities with adjustable rates totaled $45.7 million. At June 30, 2019, we held three securities that mature in one year or less,
totaling $4.0 million.

Sources of Funds



General.
Deposits have traditionally been our primary source of funds for use in lending and investment activities. In addition to deposits,
funds are derived from scheduled loan payments, investment maturities, loan prepayments, retained earnings and income on earning
assets. While scheduled loan payments and income on earning assets are relatively stable sources of funds, deposit inflows and
outflows can vary widely and are influenced by prevailing interest rates, market conditions and levels of competition. Borrowings
from the Federal Home Loan Bank of Boston and brokered certificates of deposit may be used to compensate for reductions in deposits
and to fund loan growth.



Deposits.
A majority of our depositors are persons who work or reside in Windham County and New London County, Connecticut. We offer a selection
of deposit instruments, including checking, savings, money market deposit accounts, negotiable order of withdrawal (NOW) accounts
and fixed-term certificates of deposit. Deposit account terms vary, with the principal differences being the minimum balance required,
the amount of time the funds must remain on deposit and the interest rate.





20







Interest rates paid,
maturity terms, service fees and withdrawal penalties are established on a periodic basis. Deposit rates and terms are based primarily
on current operating strategies and market rates, liquidity requirements, rates paid by competitors and growth goals. To attract
and retain deposits, we rely upon personalized customer service, long-standing relationships and competitive interest rates.



The flow of deposits
is influenced significantly by general economic conditions, changes in money market and other prevailing interest rates and competition.
The variety of deposit accounts that we offer allows us to be competitive in obtaining funds and responding to changes in consumer
demand. Based on historical experience, management believes our deposits are relatively stable. However, the ability to attract
and maintain money market accounts and certificates of deposit, and the rates paid on these deposits, have been and will continue
to be significantly affected by market conditions. At June 30, 2019, $130.3 million, or 34.0%, of our deposit accounts were certificates
of deposit, of which $78.4 million had maturities of one year or less.





21









The following table sets forth the average
distribution of total deposit accounts, by account type, for the years indicated.

Borrowings.
Our borrowings consist of advances from, and a line of credit with, the Federal Home Loan Bank of Boston, and securities sold under
agreements to repurchase. At June 30, 2019, we had an available line of credit with the Federal Home Loan Bank of Boston in the
amount of $2.4 million and access to additional Federal Home Loan Bank advances of up to $43.7 million. We also have an available
line of credit with Atlantic Community Bankers Bank in the amount of $4.0 million. There were no amounts advanced on these lines
as of June 30, 2019. At June 30, 2019, retail securities sold under agreements to repurchase were $804,000. The following table
sets forth information concerning balances and interest rates on our borrowings at the dates and for the years indicated.

Subsidiary Activities



PB Bancorp, Inc.’s
only subsidiary is Putnam Bank. Putnam Bank has three subsidiaries, Windham North Properties, LLC, PSB Realty, LLC and Putnam Bank
Mortgage Servicing Company. Windham North Properties, LLC is used to acquire title to selected properties on which Putnam Bank
forecloses. As of June 30, 2019, Windham North Properties, LLC, owned five such properties. PSB Realty, LLC owns a parcel of real
estate located immediately adjacent to Putnam Bank’s main office. This real estate is utilized as a loan center for Putnam
Bank and there are no outside tenants that occupy the premises. PSB Realty, LLC also owns the 40 High Street, Norwich branch building
and real estate. Putnam Bank Mortgage Servicing Company is a qualified “passive investment company” that is intended
to reduce Connecticut state taxes on interest earned on real estate loans.



Personnel



As of June 30,
2019, we had 81 full-time employees and 32 part-time employees. Our employees are not represented by any collective bargaining
group. Management believes that we have good working relations with our employees.



FEDERAL AND STATE TAXATION



PB Bancorp, Inc. and
Putnam Bank are subject to federal income taxation in the same general manner as other corporations, with some exceptions discussed
below.



The following discussion
of federal taxation is intended only to summarize certain pertinent federal and state income tax matters and is not a comprehensive
description of the tax rules applicable to PB Bancorp, Inc. or Putnam Bank.





23









The Company is currently
open to audit under statute of limitations by the Internal Revenue Service and state taxing authorities for the years ended June
30, 2016 through June 30, 2019. The Federal return for the tax year ended 2009 was audited in 2010. The state tax returns have
not been audited for the last five years.



Federal Taxation



Method of Accounting.
For federal income tax purposes, PB Bancorp, Inc. and Putnam Bank currently report their income and expenses on the accrual method
of accounting and use a tax year ending June 30 for filing their federal income tax returns. On December 22, 2017, the Tax
Cuts and Jobs Act (“TCJA”) was signed into law, which decreased the federal tax rate to 21.0% beginning January 1,
2018. The fiscal year ending June 30, 2018 results reflect the initial impact of TCJA, which resulted in an additional $211,000
tax provision booked as of December 31, 2017 due to the revaluation of its net deferred tax asset at the enactment date.



Bad Debt Reserves.
Prior to the Small Business Protection Act of 1996 (the “1996 Act”), Putnam Bank was permitted to establish a reserve
for bad debts and to make annual additions to the reserve. These additions could, within specified formula limits, be deducted
in arriving at our taxable income. As a result of the 1996 Act, Putnam Bank was required to use the specific charge off method
in computing its bad debt deduction beginning with its 1996 federal tax return. Savings institutions were required to recapture
any excess reserves over those established as of December 31, 1987 (base year reserve). At June 30, 2019, Putnam Bank had
no reserves subject to recapture in excess of its base year reserves.



Taxable Distributions
and Recapture. Prior to the 1996 Act, bad debt reserves created prior to January 1, 1988 were subject to recapture
into taxable income if Putnam Bank failed to meet certain thrift asset and definitional tests. Federal legislation has eliminated
these thrift-related recapture rules. At June 30, 2019, our total federal pre-1988 base year reserve was approximately $2.3 million.
However, under current law, pre-1988 base year reserves remain subject to recapture if Putnam Bank makes certain non-dividend distributions,
repurchases any of its stock, pays dividends in excess of tax earnings and profits, or ceases to maintain a bank charter.



Alternative
Minimum Tax: The Internal Revenue Code of 1986, as amended (the “Code”) imposes an alternative minimum tax
(“AMT”) at a rate of 20% on a base of regular taxable income plus certain tax preferences, which we refer to as “alternative
minimum taxable income.”  The AMT is payable to the extent such alternative minimum taxable income is in excess of an
exemption amount and the AMT exceeds the regular income tax.  Net operating losses can offset no more than 90% of alternative
minimum taxable income.  Certain AMT credits may be used as credits against regular tax liabilities in future years. 
At June 30, 2019, PB Bancorp, Inc. had no AMT payments and no net operating losses available for carry forward to future periods.
As of June 30, 2018, we had AMT credit carryforwards of $1.2 million.  Under the Tax Cuts and Jobs Act, the AMT has been eliminated
and any credits will be fully recovered by 2021.



Net Operating
Loss Carryovers. A company may carry back net operating losses to the preceding two taxable years and forward to
the succeeding 20 taxable years. Net operating losses incurred in tax years arising after December 31, 2017, are providing no carryback
and an indefinite carryforward.



Corporate
Dividends-Received Deduction. PB Bancorp, Inc. may exclude from its income 100% of dividends received from Putnam
Bank as a member of the same affiliated group of corporations. The corporate dividends-received deduction is 65% in the case of
dividends received from corporations with which a corporate recipient does not file a consolidated tax return, and corporations
which own less than 20% of the stock of a corporation distributing a dividend may deduct only 50% of dividends received or accrued
on their behalf.



State Taxation



Connecticut State
Taxation. PB Bancorp, Inc., Putnam Bank and its subsidiaries are subject to the Connecticut corporation business
tax. Both entities are required to pay the regular corporation business tax (income tax).



The Connecticut corporation
business tax is based on the federal taxable income before net operating loss and special deductions and makes certain modifications
to federal taxable income to arrive at Connecticut taxable income.  Connecticut taxable income multiplied by the state tax
rate of 7.5% to arrive at Connecticut income tax.  At June 30, 2019, PB Bancorp, Inc. and subsidiaries had $88 million of
net operating losses.  These available Connecticut net operating loss carryforwards allows the taxpayer to offset 50% of their
CT taxable income.



The State of Connecticut
permits the formation of passive investment companies by financial institutions. This legislation exempts qualifying passive investment
companies from the Connecticut corporation business tax and excludes dividends paid from a passive investment company from the
taxable income of the parent financial institution. Putnam Bank’s passive investment company, Putnam Bank Mortgage Servicing
Company, eliminated the state income tax expense of Putnam Bank. If the State of Connecticut were to pass legislation in the future
to eliminate the passive investment company exemption Putnam Bank would be subject to state income taxes in Connecticut.





24







Maryland State Taxation.As a Maryland business corporation, PB Bancorp is required to file an annual report with and pay franchise taxes to the state
of Maryland.



SUPERVISION AND REGULATION

General



Putnam Bank is a stock
savings bank organized under the laws of the State of Connecticut. The lending, investment, and other business operations of Putnam
Bank are governed by Connecticut law and regulations, as well as applicable federal law and regulations, and Putnam Bank is prohibited
from engaging in any operations not authorized by such laws and regulations. Putnam Bank is subject to extensive regulation, supervision
and examination by the Connecticut Department of Banking and, as a member of the Federal Reserve System, by the Federal Reserve
Bank of Boston. This regulation and supervision establishes a comprehensive framework of activities in which an institution may
engage and is intended primarily for the protection of the Federal Deposit Insurance Corporation’s deposit insurance fund
and depositors, and not for the protection of security holders. Putnam Bank also is a member of and owns stock in the Federal Home
Loan Bank of Boston, which is one of the 11 regional banks in the Federal Home Loan Bank System.



Under this system of
regulation, the regulatory authorities have extensive discretion in connection with their supervisory, enforcement, rulemaking
and examination activities and policies, including rules or policies that: establish minimum capital levels; restrict the timing
and amount of dividend payments; govern the classification of assets; determine the adequacy of loan loss reserves for regulatory
purposes; and establish the timing and amounts of assessments and fees. Moreover, as part of their examination authority, the banking
regulators assign numerical ratings to banks and savings institutions relating to capital, asset quality, management, liquidity,
earnings and other factors. These ratings are inherently subjective and the receipt of a less than satisfactory rating in one or
more categories may result in enforcement action by the banking regulators against a financial institution. A less than satisfactory
rating may also prevent a financial institution, such as Putnam Bank or its holding company, from obtaining necessary regulatory
approvals to access the capital markets, pay dividends, acquire other financial institutions or establish new branches.



In addition, we must
comply with significant anti-money laundering and anti-terrorism laws and regulations, Community Reinvestment Act laws and regulations,
and fair lending laws and regulations. Government agencies have the authority to impose monetary penalties and other sanctions
on institutions that fail to comply with these laws and regulations, which could significantly affect our business activities,
including our ability to acquire other financial institutions or expand our branch network.



As a savings and loan
holding company, PB Bancorp is required to comply with the rules and regulations of the Federal Reserve Board.  It is required
to file certain reports with the Federal Reserve Board and is subject to examination by and the enforcement authority of the Federal
Reserve Board.  PB Bancorp is also subject to the rules and regulations of the Securities and Exchange Commission under the
federal securities laws.



Any change in these laws or
regulations, whether by the Connecticut Department of Banking, Federal Reserve Board, Federal Deposit Insurance Corporation or
Congress, could have a material adverse impact on PB Bancorp, Inc. and Putnam Bank and their operations.



Set forth below is a brief description
of material regulatory requirements that are applicable to Putnam Bank and PB Bancorp. The description is limited to certain material
aspects of the statutes and regulations addressed, and is not intended to be a complete description of such statutes and regulations
and their effects on Putnam Bank and PB Bancorp.



Connecticut Bank Regulation



Connecticut Banking
Commissioner. The Connecticut Banking Commissioner regulates the deposit, lending and investment activities of state-chartered
savings banks, including Putnam Bank. The approval of the Connecticut Banking Commissioner is required for, among other things,
the establishment of branch offices and business combination transactions. The Commissioner conducts periodic examinations of Connecticut-chartered
banks, as does the Federal Reserve Board. The Federal Reserve Board also regulates many of the areas regulated by the Connecticut
Banking Commissioner, and federal law may limit some of the authority provided to Connecticut-chartered banks by Connecticut law.





25







Lending Activities.
Connecticut banking laws grant banks broad lending authority. With certain limited exceptions, secured and unsecured loans to any
one obligor under this statutory authority may not exceed 10.0% and 15.0%, respectively, of a bank’s equity capital and allowance
for loan losses.



Consumer Protection.We are also subject to a variety of Connecticut statutes and regulations that are intended to protect consumers and prohibit
discrimination in the granting of credit. These statutes and regulations provide for a range of sanctions for non-compliance with
their terms, including imposition of administrative fines and remedial orders, and referral to the Attorney General for prosecution
of a civil action for actual and punitive damages and injunctive relief. Certain of these statutes authorize private individual
and class action lawsuits and the award of actual, statutory and punitive damages and attorneys’ fees for certain types of
violations.



Dividends.
Putnam Bank may pay cash dividends out of its net profits. For purposes of this restriction, “net profits” represents
the remainder of all earnings from current operations. Further, the total amount of all dividends declared by a bank in any year
may not exceed the sum of a bank’s net profits for the year in question combined with its retained net profits from the preceding
two years without the specific approval of the Connecticut Banking Commissioner. Federal law also prevents an institution from
paying dividends or making other capital distributions that, if by doing so, would cause it to become “undercapitalized.”
Federal Reserve Board regulations establish limits on dividends, including requiring Federal Reserve Board approval for aggregate
dividends exceeding net income for the current year and the two prior calendar years. In addition, as a subsidiary of a savings
and loan holding company, Putnam Bank must provide prior notice to the Federal Reserve Board of any dividend. The Federal Reserve
Board has the authority to object to the dividend if deemed unsafe or unsound. No dividends may be paid to Putnam Bank’s
sole stockholder, PB Bancorp, Inc, if such dividends would reduce stockholders’ equity below the amount of the liquidation
account required by federal regulations.



Powers.
Connecticut law permits Connecticut banks to sell insurance and fixed and variable rate annuities if licensed to do so by the Connecticut
Insurance Commissioner. With the prior approval of the Connecticut Banking Commissioner, Connecticut banks are also authorized
to engage in a broad range of activities related to the business of banking, or that are financial in nature or that are permitted
under the Bank Holding Company Act or the Home Owners’ Loan Act, both federal statutes, or the regulations promulgated as
a result of these statutes.



Connecticut banks are
also authorized to engage in any activity permitted for a national bank, a federal savings association or an out of state state-chartered
bank upon filing notice with the Connecticut Banking Commissioner unless the Connecticut Banking Commissioner disapproves the activity.



Assessments.
Connecticut banks are required to pay annual assessments to the Connecticut Department of Banking to fund the Connecticut Department
of Banking’s operations. The general assessments are paid pro-rata based upon a bank’s asset size.



Enforcement.Under Connecticut law, the Connecticut Banking Commissioner has extensive enforcement authority over Connecticut banks
and, under certain circumstances, affiliated parties, insiders and agents. The Connecticut Banking Commissioner’s enforcement
authority includes cease and desist orders, fines, receivership, conservatorship, removal of officers and directors, emergency
closures, dissolution and liquidation.



Federal Bank Regulation



Capital Requirements.
Federal regulations require state banks to meet several minimum capital standards: a common equity Tier 1 capital to risk-based
assets ratio, a Tier 1 capital to risk-based assets ratio, a total capital to risk-based assets ratio and a Tier 1 capital to total
assets leverage ratio.



The risk-based
capital standards for state banks require the maintenance of common equity Tier 1 capital, Tier 1 capital and total
capital to risk-weighted assets of at least 4.5%, 6% and 8%, respectively. In determining the amount of risk-weighted assets,
all assets, including certain off-balance sheet assets (e.g., recourse obligations, direct credit substitutes, residual
interests) are multiplied by a risk weight factor assigned by the regulations based on the risks believed inherent in the
type of asset. Higher levels of capital are required for asset categories believed to present greater risk. Common equity
Tier 1 capital is generally defined as common stockholders’ equity and retained earnings. Tier 1 capital is
generally defined as common equity Tier 1 and additional Tier 1 capital. Additional Tier 1 capital includes certain
noncumulative perpetual preferred stock and related surplus and minority interests in equity accounts of consolidated
subsidiaries. Total capital includes Tier 1 capital (common equity Tier 1 capital plus additional Tier 1 capital) and Tier 2
capital. Tier 2 capital is comprised of capital instruments and related surplus, meeting specified requirements, and may
include cumulative preferred stock and long-term perpetual preferred stock, mandatory convertible securities, intermediate
preferred stock and subordinated debt. Also included in Tier 2 capital is the allowance for loan and lease losses limited to
a maximum of 1.25% of risk-weighted assets and, for institutions that have exercised an opt-out election regarding the
treatment of Accumulated Other Comprehensive Income, up to 45% of net unrealized gains on available-for-sale
equity securities with readily determinable fair market values. Calculation of all types of regulatory capital is subject to
deductions and adjustments specified in the regulations. In assessing an institution’s capital adequacy, the Federal
Reserve takes into consideration, not only these numeric factors, but qualitative factors as well, and has the authority to
establish higher capital requirements for individual associations where necessary.





26







Legislation enacted
in May 2018 requires the federal banking agencies, including the Federal Reserve Board, to establish for institutions with less
than $10 billion of assets a “community bank leverage ratio” of tangible equity capital to total average consolidated
assets of between 8 to 10%. Institutions with capital meeting the specified requirement and electing to follow the alternative
regulatory capital structure will be considered to comply with the applicable regulatory capital requirements, including the risk-based
requirements. The establishment of the community bank leverage ratio is subject to notice and comment rulemaking by the federal
regulators and the agencies issued a proposed rule in February 2019 that would set the “community bank leverage ratio”
at 9%. In addition to establishing the minimum regulatory capital requirements, the regulations limit capital distributions and
certain discretionary bonus payments to management if the institution does not hold a “capital conservation buffer”
consisting of 2.5% of common equity Tier 1 capital to risk-weighted asset above the amount necessary to meet its minimum risk-based
capital requirements. The capital conservation buffer requirement was phased in beginning January 1, 2016 at 0.625% of risk-weighted
assets and increasing each year until fully implemented at 2.5% on January 1, 2019.



The Federal Deposit
Insurance Corporation Improvement Act required each federal banking agency to revise its risk-based capital standards for insured
institutions to ensure that those standards take adequate account of interest-rate risk, concentration of credit risk, and the
risk of nontraditional activities, as well as to reflect the actual performance and expected risk of loss on multi-family residential
loans. The Federal Reserve Board, along with the other federal banking agencies, adopted a regulation providing that the agencies
will take into account the exposure of a bank’s capital and economic value to changes in interest rate risk in assessing
a bank’s capital adequacy. The Federal Reserve Board also has authority to establish individual minimum capital requirements
in appropriate cases upon determination that an institution’s capital level is, or is likely to become, inadequate in light
of the particular circumstances.



Standards for
Safety and Soundness.As required by statute, the federal banking agencies adopted final regulations and Interagency Guidelines
Establishing Standards for Safety and Soundness to implement safety and soundness standards. The guidelines set forth the safety
and soundness standards that the federal banking agencies use to identify and address problems at insured depository institutions
before capital becomes impaired. The guidelines address internal controls and information systems, internal audit system, credit
underwriting, loan documentation, interest rate exposure, asset growth, asset quality, earnings and compensation, fees and benefits.
The agencies have also established standards for safeguarding customer information. If the appropriate federal banking agency determines
that an institution fails to meet any standard prescribed by the guidelines, the agency may require the institution to submit to
the agency an acceptable plan to achieve compliance with the standard.



Interstate Banking
and Branching.Federal law permits well capitalized and well managed holding companies to acquire banks in any state, subject
to Federal Reserve Board approval, certain concentration limits and other specified conditions. Interstate mergers of banks are
also authorized, subject to regulatory approval and other specified conditions. More recent legislative amendments permit banks
to establish de novo branches on an interstate basis provided that branching is authorized by the law of the host state for the
banks chartered by that state.



Prompt Corrective
Regulatory Action.Federal law requires, among other things, that federal bank regulatory authorities take “prompt
corrective action” with respect to banks that do not meet minimum capital requirements. For these purposes, the law establishes
five capital categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically
undercapitalized.



The Federal
Reserve Board has adopted regulations to implement the prompt corrective action legislation. The regulations were amended to
incorporate the previously mentioned increased regulatory capital standards that were effective January 1, 2015. An
institution is deemed to be “well capitalized” if it has a total risk-based capital ratio of 10.0% or greater, a
Tier 1 risk-based capital ratio of 8.0% or greater, a leverage ratio of 5.0% or greater and a common equity Tier 1 ratio of
6.5% or greater. An institution is “adequately capitalized” if it has a total risk-based capital ratio of 8.0% or
greater, a Tier 1 risk-based capital ratio of 6.0% or greater, a leverage ratio of 4.0% or greater and a common equity Tier 1
ratio of 4.5% or greater. An institution is “undercapitalized” if it has a total risk-based capital ratio of less
than 8.0%, a Tier 1 risk-based capital ratio of less than 6.0%, a leverage ratio of less than 4.0% or a common equity Tier 1
ratio of less than 4.5%. An institution is deemed to be “significantly undercapitalized” if it has a total
risk-based capital ratio of less than 6.0%, a Tier 1 risk-based capital ratio of less than 4.0%, a leverage ratio of less
than 3.0% or a common equity Tier 1 ratio of less than 3.0%. An institution is considered to be “critically
undercapitalized” if it has a ratio of tangible equity (as defined in the regulations) to total assets that is equal to
or less than 2.0%. The Dodd-Frank Act provides that an institution that elects and complies
with the “community bank leverage ratio” alternative will be deemed to be “well
capitalized.”





27







At each successive
lower capital category, an insured depository institution is subject to more restrictions and prohibitions, including restrictions
on growth, restrictions on interest rates paid on deposits, restrictions or prohibitions on payment of dividends, and restrictions
on the acceptance of brokered deposits. A bank that is classified as well-capitalized, adequately capitalized, or undercapitalized
may be treated as though it were in the next lower capital category if the appropriate federal banking agency determines, after
notice and opportunity for hearing, that an unsafe or unsound condition, or an unsafe or unsound practice, warrants such treatment.
If an insured depository institution is classified in one of the undercapitalized categories, it is required to submit a capital
restoration plan to the appropriate federal banking agency, and the holding company must guarantee the performance of that plan.
An undercapitalized bank’s compliance with a capital restoration plan is required to be guaranteed by any company that controls
the undercapitalized institution in an amount equal to the lesser of 5.0% of the institution’s total assets when deemed undercapitalized
or the amount necessary to achieve the status of adequately capitalized. If an “undercapitalized” bank fails to submit
an acceptable plan, it is treated as if it is “significantly undercapitalized.” “Significantly undercapitalized”
banks must comply with one or more of a number of additional restrictions including, but not limited to, an order by the Federal
Reserve Board to sell sufficient voting stock to become adequately capitalized, reduce total assets, cease receipt of deposits
from correspondent banks or dismiss directors or officers, and restrictions on interest rates paid on deposits, compensation of
executive officers and capital distributions by the parent holding company. “Critically undercapitalized” institutions
are subject to additional measures including, subject to a narrow exception, the appointment of a receiver or conservator within
270 days after it obtains such status.



Transaction with
Affiliates and Regulation W of the Federal Reserve Regulations.Transactions between banks and their affiliates are governed
by federal law. An affiliate of a bank is any company or entity that controls, is controlled by or is under common control with
the bank. In a holding company context, the parent bank holding company and any companies which are controlled by such parent holding
company are affiliates of the bank (although subsidiaries of the bank itself, except financial subsidiaries, are generally not
considered affiliates). Generally, Section 23A of the Federal Reserve Act and the Federal Reserve Board’s Regulation W limit
the extent to which the bank or its subsidiaries may engage in “covered transactions” with any one affiliate to an
amount equal to 10.0% of such institution’s capital stock and surplus, and with all such transactions with all affiliates
to an amount equal to 20.0% of such institution’s capital stock and surplus. Section 23B applies to “covered transactions”
as well as to certain other transactions and requires that all such transactions be on terms substantially the same, or at least
as favorable, to the institution or subsidiary as those provided to a non-affiliate. The term “covered transaction”
includes the making of loans to, purchase of assets from, and issuance of a guarantee on behalf of an affiliate, and similar transactions.
Section 23B transactions also include the provision of services and the sale of assets by a bank to an affiliate. In addition,
loans or other extensions of credit by the financial institution to the affiliate are required to be collateralized in accordance
with the requirements set forth in Section 23A of the Federal Reserve Act.



Sections 22(h) and
(g) of the Federal Reserve Act place restrictions on loans to a bank’s insiders, i.e., executive officers, directors
and principal shareholders. Under Section 22(h) of the Federal Reserve Act, loans to a director, an executive officer and
a greater than 10.0% shareholder of a financial institution, and certain affiliated interests of these, together with all other
outstanding loans to such person and affiliated interests, may not exceed specified limits. Section 22(h) of the Federal Reserve
Act also requires that loans to directors, executive officers and principal shareholders be made on terms substantially the same
as offered in comparable transactions to other persons and also requires prior board approval for certain loans. In addition, the
aggregate amount of extensions of credit by a financial institution to insiders cannot exceed the institution’s unimpaired
capital and surplus. Section 22(g) of the Federal Reserve Act places additional restrictions on loans to executive officers.



Enforcement.The Federal Reserve Board and, secondarily, the Federal Deposit Insurance Corporation, have extensive enforcement authority
over insured state savings banks, including Putnam Bank. The enforcement authority includes, among other things, the ability to
assess civil money penalties, issue cease and desist orders and remove directors and officers. In general, these enforcement actions
may be initiated in response to violations of laws and regulations, breaches of fiduciary duty and unsafe or unsound practices.



Federal Insurance
of Deposit Accounts.Putnam Bank is a member of the Deposit Insurance Fund, which is administered by the Federal Deposit
Insurance Corporation. Deposit accounts in Putnam Bank are insured up to a maximum of $250,000 for each separately insured depositor.





28







The Federal
Deposit Insurance Corporation imposes an assessment for deposit insurance on all depository institutions. Under the Federal
Deposit Insurance Corporation’s risk-based assessment system, insured institutions are assessed based on perceived risk
to the Deposit Insurance Fund. Perceived risk to the deposit insurance fund is currently determined by the FDIC using a
combination of examination ratings and financial modeling designed to estimate the probability that an institution fails over
a three year period. The range of assessments for banks of less than $10 billion in assets is
11/2 basis points to 30 basis points of total assets less tangible capital, effective July 1,
2016.



The Federal Deposit
Insurance Corporation has authority to increase insurance assessments. A significant increase in insurance premiums would likely
have an adverse effect on the operating expenses and results of operations of Putnam Bank. Future insurance assessment rates cannot
be predicted.



Insurance of deposits
may be terminated by the Federal Deposit Insurance Corporation upon a finding that the institution has engaged in unsafe or unsound
practices, is in an unsafe or unsound condition to continue operations or has violated any applicable law, regulation, rule order
or regulatory condition imposed in writing. We do not know of any practice, condition or violation that might lead to termination
of deposit insurance.



In addition to the
Federal Deposit Insurance Corporation assessments, the Financing Corporation (“FICO”) is authorized to impose and collect,
with the approval of the Federal Deposit Insurance Corporation, assessments for anticipated payments, issuance costs and custodial
fees on bonds issued by the FICO in the 1980s to recapitalize the former Federal Savings and Loan Insurance Corporation. The bonds
issued by the FICO are due to mature by year end 2019. For the quarter ended June 30, 2019, the annualized FICO assessment was
equal to 0.12 basis points of total assets less tangible capital.



Privacy Regulations.Federal regulations generally require that Putnam Bank disclose its privacy policy, including identifying with whom it
shares a customer’s “non-public personal information,” to customers at the time of establishing the customer
relationship and annually thereafter. In addition, Putnam Bank is required to provide its customers with the ability to “opt-out”
of having their personal information shared with unaffiliated third parties and not to disclose account numbers or access codes
to non-affiliated third parties for marketing purposes. Putnam Bank currently has a privacy protection policy in place and believes
that such policy is in compliance with the regulations.



Community Reinvestment
Act.Under the Community Reinvestment Act, or CRA, as implemented by federal regulations, a state member bank has a continuing
and affirmative obligation, consistent with its safe and sound operation, to help meet the credit needs of its entire community,
including low and moderate income neighborhoods. The CRA does not establish specific lending requirements or programs for financial
institutions nor does it limit an institution’s discretion to develop the types of products and services that it believes
are best suited to its particular community, consistent with the CRA. The CRA does require the Federal Reserve Board, in connection
with its examination of a state member bank, to assess the institution’s record of meeting the credit needs of its community
and to take such record into account in its evaluation of certain applications by such institution, including applications to acquire
branches and other financial institutions. The CRA requires a written evaluation of an institution’s CRA performance utilizing
a four-tiered descriptive rating system. Putnam Bank’s latest federal CRA rating was “Satisfactory.”



Connecticut has its
own statutory counterpart to the CRA that is also applicable to Putnam Bank. Connecticut law requires the Connecticut Banking Commissioner
to consider, but not be limited to, a bank’s record of performance under Connecticut law in considering any application by
a bank to establish a branch or other deposit-taking facility, to relocate an office or to merge or consolidate with or acquire
the assets and assume the liabilities of any other banking institution. Putnam Bank's most recent CRA rating under Connecticut
law was "Satisfactory."



Consumer Protection
and Fair Lending Regulations.Connecticut savings banks are subject to a variety of federal statutes and regulations that
are intended to protect consumers and prohibit discrimination in the granting of credit. These statutes and regulations provide
for a range of sanctions for non-compliance with their terms, including imposition of administrative fines and remedial orders,
and referral to the Attorney General for prosecution of a civil action for actual and punitive damages and injunctive relief. Certain
of these statutes authorize private individual and class action lawsuits and the award of actual, statutory and punitive damages
and attorneys’ fees for certain types of violations.



USA
Patriot Act.Putnam Bank is subject to the USA PATRIOT Act, which gave federal agencies additional powers to address
terrorist threats through enhanced domestic security measures, expanded surveillance powers, increased information sharing,
and broadened anti-money laundering requirements. By way of amendments to the Bank Secrecy Act, Title III of the USA PATRIOT
Act provided measures intended to encourage information sharing among bank regulatory agencies and law enforcement bodies.
Further, certain provisions of Title III impose affirmative obligations on a broad range of financial institutions, including
banks, thrifts, brokers, dealers, credit unions, money transfer agents, and parties registered under the Commodity Exchange
Act.





29







Other Regulations



Interest and other
charges collected or contracted for by Putnam Bank are subject to state usury laws and federal laws concerning interest rates.
Loan operations are also subject to state and federal laws applicable to credit transactions, such as the:



| | · | Home Mortgage Disclosure Act of 1975, requiring financial institutions to provide information to
enable the public and public officials to determine whether a financial institution is fulfilling its obligation to help meet the
housing needs of the community it serves;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Equal Credit Opportunity Act, prohibiting discrimination on the basis of race, creed or other prohibited
factors in extending credit;
| | - | -------------------------------------------------------------------------------------------------------------------------------------



| | · | Fair Credit Reporting Act of 1978, governing the use and provision of information to credit reporting
agencies; and
| | - | -------------------------------------------------------------------------------------------------------------------



| | · | Rules and regulations of the various federal and state agencies charged with the responsibility
of implementing such federal and state laws.
| | - | --------------------------------------------------------------------------------------------------------------------------------------------



The deposit
operations of Putnam Bank also are subject to, among others, the:



| | · | Right to Financial Privacy Act, which imposes a duty to maintain confidentiality of consumer financial
records and prescribes procedures for complying with administrative subpoenas of financial records;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Check Clearing for the 21st Century Act (also known as “Check 21”), which gives “substitute
checks,” such as digital check images and copies made from that image, the same legal standing as the original paper check;
and
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Electronic Funds Transfer Act and Regulation E promulgated thereunder, which govern automatic deposits
to and withdrawals from deposit accounts and customers’ rights and liabilities arising from the use of automated teller machines
and other electronic banking services.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Federal Reserve System



The Federal Reserve
Board regulations require depository institutions to maintain non-interest-earning reserves against their transaction accounts
(primarily NOW and regular checking accounts). The amount of required reserves is adjusted annually. For 2019, the Federal Reserve
Board’s regulations require that reserves be maintained against aggregate transaction accounts as follows: for that portion
of transaction accounts aggregating $124.2 million or less, the reserve requirement is 3.0%; amounts greater than $124.2 million
require a 10.0% reserve. The first $16.3 million of otherwise reservable balances is exempted from the reserve requirements. Putnam
Bank is in compliance with these requirements.



Federal Home Loan Bank System



Putnam Bank is a
member of the Federal Home Loan Bank System, which consists of 11 regional Federal Home Loan Banks. The Federal Home Loan
Bank provides a central credit facility primarily for member institutions. Members of the Federal Home Loan Bank are required
to acquire and hold shares of capital stock in the Federal Home Loan Bank. Putnam Bank was in compliance with this
requirement at June 30, 2019. Based on redemption provisions of the Federal Home Loan Bank of Boston, the stock has no quoted
market value and is carried at cost. At its discretion, the Federal Home Loan Bank of Boston may declare dividends on the
stock. The Federal Home Loan Banks are required to provide funds for certain purposes including contributing funds for
affordable housing programs. These requirements could reduce the amount of dividends that the Federal Home Loan Banks pay to
their members and result in the Federal Home Loan Banks imposing a higher rate of interest on advances to their members. For
the fiscal year ended June 30, 2019, the Federal Home Loan Bank paid quarterly dividends equal to an average annual yield of
6.34%. There can be no assurance that such dividends will continue in the future. Further, there can be no assurance that the
impact of recent or future legislation on the Federal Home Loan Banks also will not cause a decrease in the value of the
Federal Home Loan Bank of Boston stock held by Putnam Bank.





30







Sarbanes-Oxley Act



The Sarbanes-Oxley
Act of 2002 was enacted in response to public concerns regarding corporate accountability in connection with certain accounting
scandals. The stated goals of the Sarbanes-Oxley Act are to increase corporate responsibility, to provide for enhanced penalties
for accounting and auditing improprieties at publicly traded companies, and to protect investors by improving the accuracy and
reliability of corporate disclosures pursuant to the securities laws.



We have existing policies,
procedures and systems designed to comply with these regulations, and we are further enhancing and documenting such policies, procedures
and systems to ensure continued compliance with these regulations.



Holding Company Regulation



PB Bancorp is a unitary
savings and loan holding company subject to regulation and supervision by the Federal Reserve Board. The Federal Reserve Board
has enforcement authority over PB Bancorp and its non-savings institution subsidiaries. Among other things, this authority permits
the Federal Reserve Board to restrict or prohibit activities that are determined to be a risk to Putnam Bank.



As a savings and loan
holding company, PB Bancorp’s activities are limited to those activities permissible by law for financial holding companies
(if PB Bancorp makes an election to be treated as a financial holding company and meets the other requirements to be a financial
holding company) or multiple savings and loan holding companies. A financial holding company may engage in activities that are
financial in nature, incidental to financial activities or complementary to a financial activity. Such activities include lending
and other activities permitted for bank holding companies under Section 4(c)(8) of the Bank Holding Company Act, and selling insurance
and underwriting equity securities. Multiple savings and loan holding companies are authorized to engage in activities specified
by federal regulation.



Federal law prohibits
a savings and loan holding company from directly or indirectly acquiring more than 5% of another savings institution or savings
and loan holding company without prior written approval of the Federal Reserve Board, and from acquiring or retaining control of
any depository institution not insured by the Federal Deposit Insurance Corporation. In evaluating applications by holding companies
to acquire savings institutions, the Federal Reserve Board must consider such things as the financial and managerial resources
and future prospects of the company and institution involved, the effect of the acquisition on and the risk to the federal deposit
insurance fund, the convenience and needs of the community and competitive factors. A savings and loan holding company may not
acquire a savings institution in another state and hold the target institution as a separate subsidiary unless it is a supervisory
acquisition under Section 13(k) of the Federal Deposit Insurance Act or the law of the state in which the target is located authorizes
such acquisitions by out-of-state companies.



Savings and loan holding
companies historically had not been subjected to consolidated regulatory capital requirements. However, the Dodd-Frank Act required
the Federal Reserve Board to establish minimum consolidated capital requirements for all depository institution holding companies
that are as stringent as those required for the insured depository subsidiaries. Subsequent legislation was enacted in December
2014 that required the Federal Reserve Board to extend the applicability of its “Small Bank Holding Company” exemption
from consolidated holding company capital requirements from holding companies of up to $500 million of consolidated assets to holding
companies of up to $1 billion. Regulations implementing this amendment were effective May 15, 2015. Legislation enacted in May
2018 directed the Federal Reserve to extend the exemption to holding companies of up to $3 billion in consolidated assets, which
was done in August 2018. Consequently, savings and loan holding companies with under $3 billion in consolidated assets, such as
PB Bancorp, remain exempt from consolidated regulatory capital requirements, unless the Federal Reserve determines otherwise in
particular cases.



The Dodd-Frank Act
extended the “source of strength” doctrine to savings and loan holding companies. The Federal Reserve Board has promulgated
regulations implementing the “source of strength” policy that require holding companies to act as a source of strength
to their subsidiary depository institutions by providing capital, liquidity and other support in times of financial stress.





31







The Federal
Reserve Board has issued a policy statement regarding the payment of dividends and the repurchase of shares of common stock
by bank holding companies and savings and loan holding companies. In general, the policy provides that dividends should be
paid only out of current earnings and only if the prospective rate of earnings retention by the holding company appears
consistent with the organization’s capital needs, asset quality and overall financial condition. Regulatory guidance
provides for prior regulatory consultation with respect to capital distributions in certain circumstances such as where the
company’s net income for the past four quarters, net of dividends previously paid over that period, is insufficient to
fully fund the dividend or the company’s overall rate of earnings retention is inconsistent with the company’s
capital needs and overall financial condition. The ability of a holding company to pay dividends may be restricted if a
subsidiary bank becomes undercapitalized. The policy statement also states that a holding company should inform the Federal
Reserve Board supervisory staff prior to redeeming or repurchasing common stock or perpetual preferred stock if the holding
company is experiencing financial weaknesses or if the repurchase or redemption would result in a net reduction, as of the
end of a quarter, in the amount of such equity instruments outstanding compared with the beginning of the quarter in which
the redemption or repurchase occurred. These regulatory policies may affect the ability of PB Bancorp to pay dividends,
repurchase shares of common stock or otherwise engage in capital distributions.



In order for PB Bancorp
to be regulated by the Federal Reserve Board as a savings and loan holding company, rather than as a bank holding company, Putnam
Bank must qualify as a “qualified thrift lender” under federal regulations or satisfy the “domestic building
and loan association” test under the Internal Revenue Code. Under the qualified thrift lender test, a savings institution
is required to maintain at least 65% of its “portfolio assets” (total assets less: (i) specified liquid assets
up to 20% of total assets; (ii) intangible assets, including goodwill; and (iii) the value of property used to conduct
business) in certain “qualified thrift investments” (primarily residential mortgages and related investments, including
certain mortgage-backed and related securities) in at least nine out of each twelve month period. At June 30, 2019, Putnam Bank
maintained 73.3% of its portfolio assets in qualified thrift investments and was in compliance with the qualified thrift lender
requirement.



Change in Control Regulations



Under the Change in
Bank Control Act, no person may acquire control of a savings and loan holding company such as PB Bancorp unless the Federal Reserve
Board has been given 60 days’ prior written notice and has not issued a notice disapproving the proposed acquisition, taking
into consideration certain factors, including the financial and managerial resources of the acquirer and the competitive effects
of the acquisition. Control, as defined under federal law, means ownership, control of or holding irrevocable proxies representing
more than 25% of any class of voting stock, control in any manner of the election of a majority of the institution’s directors,
or a determination by the regulator that the acquiror has the power, directly or indirectly, to exercise a controlling influence
over the management or policies of the institution. Acquisition of more than 10% of any class of a savings and loan holding company’s
voting stock constitutes a rebuttable determination of control under the regulations under certain circumstances including where,
as will be the case with PB Bancorp, the issuer has registered securities under Section 12 of the Securities Exchange Act of 1934.



In addition, federal
regulations provide that no company may acquire control of a savings and loan holding company without the prior approval of the
Federal Reserve Board. Any company that acquires such control becomes a “savings and loan holding company” subject
to registration, examination and regulation by the Federal Reserve Board.



Acquisition of 10%
or more of the stock of Connecticut-chartered institutions or companies controlling Connecticut institutions may also require the
prior approval of the Connecticut Banking Commissioner.

Benefit Plans and Agreements



Change in Control
Agreements.Putnam Bank has entered into change in control agreements with Messrs. Borner and Halloran. The change in control
agreements provide a benefit in the event of an involuntary termination of employment or a resignation for good reason (as defined
in the agreement) within twelve months following a change in control (as defined in the agreement) equal to three times (two times
for Mr. Halloran) the executive’s base salary, payable in a lump sum. The amount of the payment to be made in connection
with a change in control will be reduced, if necessary, to an amount that is $1.00 less than the amount that would otherwise be
an “excess parachute payment” under Section 280G of the Internal Revenue Code of 1986, as amended, only if this will
result in the executive receiving a greater total payment as measured on an after-tax basis. Assuming Messrs. Borner and Halloran
had been terminated in connection with a change in control as of June 30, 2019, Messrs. Borner and Halloran would have received
maximum aggregate cash severance payments of approximately $1,065,000 and $448,738, respectively.



Deferred Compensation
Retirement Plan.Putnam Bank maintains a deferred compensation retirement plan for the benefit of directors designated
by the Board to participate in the plan. The plan was frozen as of July 1, 2004, and no further contributions have been made to
the plan since that date. On February 17, 2016, the plan was amended to convert each participant’s account balance held by
a rabbi trust established for the plan into an unfunded bookkeeping account maintained by Putnam Bank. As of each valuation date,
the participants’ accounts have been credited with an investment return equal to the New York prime rate of interest, compounded
monthly.





36







The
participant’s bookkeeping account will be distributed to the participant (or the participant’s beneficiary in the
event of death) in periodic installments (at least annually) as elected by the participant or the participant’s
beneficiary. In the event the annual installment exceeds $10,000, the maximum distribution period will be ten years. In the
event the participant’s account is less than $10,000, distribution will be made in a lump sum. Distribution will be
made within 60 days of a participant’s normal or late retirement. In the event of termination of service due to
disability, distribution will be made within 60 days following the close of the plan year in which termination of service
occurs. In the event a participant terminates service for any reason other than normal retirement, disability or death,
distribution will commence within the later of 60 days following the close of the plan year in which the participant
terminates service or 60 days after the participant’s election to commence payment is delivered to the plan
administrator. In the event of a participant’s death prior to termination of service, the participant’s account
will be distributed to his or her beneficiary. If the participant dies after termination of service but prior to the complete
distribution of his account balance, the undistributed balance will be distributed to the participant’s beneficiary in
annual installments over three years unless the beneficiary elects otherwise.



Incentive Plans. Beginning with the fiscal year ended June 30, 2018, incentive compensation for the Named Executive Officers are governed
by the Putnam Bank Senior Management Short Term Incentive Plan (the “Plan”). The financial criteria for bonuses are
return on average equity, efficiency ratio and return on average assets, with bonuses calculated based upon comparing Putnam Bank’s
performance with that of a peer group of financial institutions. Performance is calculated based on results for the calendar year.
Bonus amounts are limited to 25% of base salary for the President and Chief Executive Officer and 20% of base salary for the other
officers covered by the Plan. For the calendar year ended December 31, 2018, Putnam Bank’s performance on return on average
equity, efficiency ratio and return on average assets were 6.08%, 71.40% and 0.82%, respectively, compared to the peer group performance
of 4.62%, 80.12% and 0.64%, respectively, resulting in bonus amounts of 16.95% of base salary for Mr. Borner and 14.52% of base
salary for other participating officers, including Mr. Halloran. The value of these bonus amounts is reflected in the Summary Compensation
Table, above.

Stock Benefit Plans



Employee Stock
Ownership Plan and Trust.  The Board of Directors of Putnam Bank has adopted an employee stock ownership plan. 
Employees who are at least 21 years old with at least one year of employment with Putnam Bank are eligible to participate. The
employee stock ownership plan trust borrowed funds from the Company and previously borrowed funds from the Company’s predecessor,
PSB Holdings, Inc., and used those funds to purchase shares of common stock in the Company’s stock offering and in PSB Holdings,
Inc.’s 2004 stock offering.  As a result, as of June 30, 2019, the employee stock ownership plan now holds 605,986 shares
of Company common stock.  Collateral for the loan is the common stock purchased by the employee stock ownership plan. The
loan is being repaid principally from Putnam Bank discretionary contributions to the employee stock ownership plan over a period
of up to 20 years.  The loan documents provide that the loan may be repaid over a shorter period, without penalty for prepayments.
The interest rate for the loan is a floating rate equal to the prime rate.  Shares purchased by the employee stock ownership
plan are held in a suspense account for allocation among participants as the loan is repaid.





37







Contributions to
the employee stock ownership plan and shares released from the suspense account in an amount proportional to the repayment of
the employee stock ownership plan loan are allocated among employee stock ownership plan participants on the basis of
compensation in the year of allocation. Benefits under the plan vest at the rate of 20% per year, starting upon completion of
three years of credited service, and will be fully vested upon completion of seven years of credited service, with credit
given to participants for years of credited service with Putnam Bank’s mutual predecessor prior to the adoption of the
plan. A participant’s interest in his or her account under the plan fully vests in the event of termination of service
due to a participant’s early or normal retirement, death, disability, or upon a change in control (as defined in the
plan). Vested benefits are payable in common stock and/or cash. Putnam Bank’s contributions to the employee stock
ownership plan are discretionary, subject to the loan terms and tax law limits. Therefore, benefits payable under the
employee stock ownership plan cannot be estimated. Pursuant to Financial Accounting Standards Board Accounting Standards
Codification 718-40, the Company records compensation expense each year in an amount equal to the fair market value of the
shares released from the suspense account. In the event of a change in control, the employee stock ownership plan will
terminate.



Stock-Based Incentive
Plan.The Company has adopted the PB Bancorp, Inc. 2017 Stock-Based Incentive Plan (the “Incentive Plan”)
to provide officers, employees and directors of the Company or the Bank with additional incentives to share in the growth and performance
of the Company. The Incentive Plan was approved by stockholders on February 17, 2017.



Subject to permitted
adjustments for certain corporate transactions, the Incentive Plan authorizes the issuance or delivery to participants of up to
634,573 shares of Company common stock pursuant to grants of incentive and non-statutory stock options, restricted stock awards
and restricted stock units. Of this number, the maximum number of shares of Company common stock that may be issued under the Incentive
Plan pursuant to the exercise of stock options is 453,267 shares, and the maximum number of shares of Company common stock that
may be issued as restricted stock awards or restricted stock units is 181,306 shares. As of June 30, 2019, there
were 33,556 restricted stock awards or units and 65,937 stock options that remain available for future grants under the Incentive
Plan.

| | ITEM 13. | Certain Relationships and Related Transactions, and Director Independence
| | -------- | -------------------------------------------------------------------------



Transactions with Certain Related Persons



All transactions between
the Company and its executive officers, directors, holders of 10% or more of the shares of its common stock and affiliates thereof,
are on terms no less favorable to the Company than could have been obtained by it in arm’s-length negotiations with unaffiliated
persons. Such transactions must be approved by a majority of the independent directors of the Company not having any interest in
the transaction. In the ordinary course of business, Putnam Bank makes loans available to its directors, officers and employees.
These loans are made in the ordinary course of business on substantially the same terms, including interest rate and collateral,
as those prevailing at the time for comparable loans with persons not related to Putnam Bank. Management believes that these loans
neither involve more than the normal risk of collectibility nor present other unfavorable features.





39







Section 402 of the
Sarbanes-Oxley Act of 2002 generally prohibits an issuer from: (1) extending or maintaining credit; (2) arranging for the extension
of credit; or (3) renewing an extension of credit in the form of a personal loan for an officer or director. There are several
exceptions to this general prohibition, one of which is applicable to the Company. Sarbanes-Oxley does not apply to loans made
by a depository institution that is insured by the FDIC and is subject to the insider lending restrictions of the Federal Reserve
Act. All loans to Putnam Bank’s directors and officers are made in conformity with the Federal Reserve Act and applicable
regulations.



In accordance
with the listing standards of the NASDAQ Stock Market, any transactions that would be required to be reported under this
section of this Proxy Statement must be reviewed by our audit committee or another independent body of the board of
directors. In addition, any transaction with a director is reviewed by and subject to approval of the members of the board of
directors who are not directly involved in the proposed transaction to confirm that the transaction is on terms that are no
less favorable as those that would be available to us from an unrelated party through an arms-length transaction.



Board Independence



The Board of Directors
has determined that, except for Messrs. Borner, Halloran and Sinha, each member of the Board is an “independent director”
as defined in the NASDAQ listing rules.  Messrs. Borner, Halloran are not considered independent because they serve as executive
officers of the Company and Mr. Sinha is an officer of Putnam Bank. [CONFIRM] In evaluating the independence of our
independent directors, we found no transactions between us and our independent directors that are not required to be reported under
 “—Transactions With Certain Related Persons,” above, and that had an impact on our determination as to the independence
of our directors.



| | ITEM 14. | Principal Accountant Fees and Services
| | -------- | --------------------------------------



Audit Fees



The following sets
forth information with respect to the fees billed by the Company for the fiscal years ended June 30, 2019 and 2018 to Wolf &
Company, P.C.



Audit Fees.
The fees for professional services rendered by Wolf & Company, P.C. for the audit of the Company’s annual financial statements
and for the review of the consolidated financial statements included in the Company’s quarterly reports on Form 10-Q were
$111,388 for 2019 and $112,200 for 2018.



Audit-Related
Fees. There were no additional fees for 2019 or 2018 professional services by Wolf & Company, P.C., that were reasonably
related to the performance of the audit.



Tax Fees. 
There were no fees for professional tax services such as tax advice, tax planning, tax compliance and the review of tax returns
paid to Wolf & Company, P.C. for 2019 or 2018.



All Other Fees.
There were fees of $3,300 billed to the Company by Wolf & Company, P.C. during the fiscal year ended June 30, 2019 and $3,350
during the fiscal year ended June 30, 2018.



The Audit Committee
considered whether the provision of non-audit services was compatible with maintaining the independence of its independent registered
public accounting firm for fiscal 2019 and 2018. The Audit Committee concluded that performing such services in fiscal 2019 and
2018 did not affect the independent registered public accounting firm’s independence in performing its function as auditors
of the Company’s financial statements.



Policy on Audit Committee Pre-Approval of Audit
and Non-Audit Services of Independent Auditor



The Audit Committee’s
policy is to pre-approve all audit and non-audit services provided by the Company’s independent registered public accounting
firm. These services may include audit services, audit-related services, tax services and other services. Pre-approval is generally
provided for up to one year and any pre-approval is detailed as to particular service or category of services and is generally
subject to a specific budget. The Audit Committee has delegated pre-approval authority to its Chairman when expedition of services
is necessary. The independent registered public accounting firm and management are required to periodically report to the full
Audit Committee regarding the extent of services provided by the independent registered public accounting firm in accordance with
this pre-approval, and the fees for the services performed to date. All other fees for the past two fiscal years were pre-approved
by the Audit Committee.
