Merger with Bank of Marin Bancorp



On April 16, 2021, the Company entered into a Merger Agreement that, upon the
terms and subject to the conditions set forth therein, the Company will merge
(the "Merger") with and into Bank of Marin Bancorp (the Marin Bancorp") with
Marin Bancorp surviving, followed immediately thereafter by the merger (the
"Bank Merger") of American River Bank, with and into Bank of Marin, a California
corporation and wholly-owned subsidiary of Marin Bancorp, with Bank of Marin
surviving. The Merger Agreement was approved by the Board of Directors of each
of the Company and Marin Bancorp.

28





Subject to the terms and conditions of the Merger Agreement, at the effective
time of the Merger (the "Effective Time"), each outstanding share of the
Company's common stock, excluding certain specified shares, will be converted
into the right to receive 0.575 (the "Exchange Ratio") of a share of Marin
Bancorp common stock (the "Merger Consideration"). In addition, at the Effective
Time, (i) each option to purchase shares of Company common stock, whether vested
or unvested, that is outstanding immediately prior to the Effective Time will be
canceled and exchanged for the right to receive an amount of cash equal to the
product of (x) the total number of shares of Company common stock subject to
such option and (y) the excess, if any, of (A) the product of (1) the volume
weighted average price of Marin Bancorp common stock on each of the last fifteen
trading days ending on the second trading day immediately prior to the Effective
Time, and (2) the Exchange Ratio, over (B) the exercise price per share under
such option, less applicable taxes required to be withheld with respect to such
payment; and (ii) any vesting conditions applicable to each outstanding
restricted stock award and each outstanding restricted stock unit will
accelerate in full, and each such restricted stock award and restricted stock
unit will be treated as any other outstanding share of Company common stock
entitled to receive the Merger Consideration. We cannot provide any assurance on
whether or not the Merger will close in a timely fashion or at all.

Potential Impact of COVID-19


2020 began with optimism based off the progress made in 2019, but that was
stalled when the novel coronavirus pandemic ("COVID-19") arrived and created a
global health crisis that has set off an economic crisis causing significant
disruption in the local, national and global economies and financial markets.
Continuation and further spread of COVID-19 could cause additional quarantines,
shutdowns, reduction in business activity and financial transactions, labor
shortages, supply chain interruptions and overall economic and financial market
instability. The disruptions in the economy has impaired and may continue to
impair the ability of some of our borrowers to make their loan payments, which
could result in significant increases in delinquencies, defaults, foreclosures,
declining collateral values, and credit losses on our loans. Similarly, because
of changing economic and market conditions, we may be required to recognize
credit losses on the investment securities we hold as well.  COVID-19 may also
continue to materially disrupt banking and other financial activity generally
and may result in a decline in demand for our products and services, including
loans and deposits which could negatively impact our liquidity position and our
growth strategy. Any one or more of these developments could have a material
adverse effect on our business, operations, consolidated financial condition,
and consolidated results of operations.

In response to the anticipated economic effects of COVID-19, the Board of
Governors of the Federal Reserve System (the "FRB") has taken a number of
actions that have significantly affected the financial markets in the United
States, including actions intended to result in substantial decreases in market
interest rates, including reducing the target federal funds range by 150 basis
points during the first quarter of 2020 to 0% and announcing further
quantitative easing in response to the expected economic downturn caused by
COVID-19. We expect that these reductions in interest rates, among other actions
of the FRB and the Federal government generally, especially if prolonged, will
adversely affect our net interest income, margins and profitability.



In addition to preparing the Company to handle the impact of the economic
crisis, protecting the health and wellbeing of our employees and the financial
viability of our clients, is now our highest priority. The Company quickly put
its pandemic plan into action to adjust to the impact of the health issues from
the COVID-19 pandemic on our employees and our clients. We have been working
with our clients by assisting them with loan payment deferrals and maintaining
service at all of our branch locations, subject to reduced operating hours. We
are encouraging the use of our digital and electronic channels and our night
depositories, all the while adhering to the ever-evolving State and Federal
guidelines. We have been participating in the Small Business Administration's
("SBA's") Paycheck Protection Program ("PPP") under the Coronavirus Aid, Relief
and Economic Security ("CARES") Act to help provide loans to our business
clients to provide them with additional working capital to enable them to retain
their employees.

We believe the COVID-19 pandemic has already impacted our local economy when
Federal, State and local shelter-in-place recommendations were enacted in our
markets in March 2020 causing many businesses to close and workers to be
furloughed or become unemployed. Essential purpose entities such as medical
professionals, food and agricultural businesses, and transportation and
logistical businesses were exempted from the closures; however, unemployment
rates increased in our local market area. Prior to the pandemic unemployment
rates were at all-time lows. At the end of February 2020, the unemployment rate
in Sacramento County was 3.7%, in Sonoma County it was 2.8%, and in Amador
County it was 4.4%. By the end of May 2020, these numbers increased to 14.1% in
Sacramento County, 12.7%, in Sonoma County, and 15.1% in Amador County. With
some businesses allowed to reopen these rates have decreased to 7.4% in
Sacramento County, 6.0%, in Sonoma County, and 7.4% in Amador County as of March
31, 2021. While shelter-in-place restrictions were eased in our markets during
the second quarter of 2020, and just as many businesses were opening, new
restrictions were put in place, essentially eliminating the progress that had
been made until later in the third quarter when selected areas had the
restrictions eased again. New restrictions went in place throughout the State
later in 2020, which were then eased in January 2021. With the successful
rollout of the pandemic vaccines, more business have been able to reopen in

the
first quarter of 2021.

29





The Company has taken measures to protect the health and safety of its employees
by implementing remote work arrangements to the full extent possible, and by
adjusting banking offices hours and operational measures to promote social
distancing. The Company will continue to analyze economic conditions in our
geographic markets and perform stress testing of our investment and loan
portfolios. The Company does not currently have a stock repurchase program in
place. Our Board of Directors will evaluate whether or not to implement a
program following such time that the economic impact of the COVID-19 has been
assessed and minimized. On April 21, 2021, the Company announced a $0.07 per
share cash dividend payable on May 19, 2021 to shareholders of record on May 4,
2021. Future cash dividend decisions will consider, among other business
considerations, the impact of COVID-19 on the Company's capital and liquidity
levels. Based on the Company's current capital levels, historical conservative
underwriting policies, low loan-to-deposit ratio, concentration and geographical
diversification of the loan portfolio, the Company currently expects to be able
to manage the economic risks and uncertainties associated with the COVID-19
pandemic with sufficient liquidity and capital levels.

While the Company is not exposed to large oil and gas, airline, or the
entertainment industries we have been evaluating the exposure to potentially
increased loan losses related to the COVID-19 pandemic and have identified the
following industry segments most impacted by the pandemic as of March 31, 2021:

                                                     Percentage of total
                                                        non PPP loans
          Industry              Loan Balance           outstanding (1)
Hospitality                     $     918,000                         0.2 %
Churches                        $  21,692,000                         5.2 %
Restaurants                     $   5,725,000                         1.4 %
Eldercare                       $   6,440,000                         1.5 %
School/childcare                $   5,355,000                         1.3 %
Recreation (golf/sportsclubs)   $   1,668,000                         0.4 %
Oil/Gas                         $   8,924,000 (2)                     2.1 %


(1) The PPP loans are 100% guaranteed by the SBA. By removing them from the total

loans outstanding in this calculation, we believe the table represents a more

reflective picture of the risk in the loan portfolio. The percentage of loans

outstanding is, therefore, calculated excluding the PPP loans from the total

loans. PPP loans as of March 31, 2021 were $57,486,000, therefore, gross

non-PPP loans were $420,030,000.

(2) This total represents gas stations with convenience stores; gas station,

convenience store and car washes; auto restoration companies; gas station,


     car washes; and drive though oil change and car wash facilities.


The Company is closely monitoring the effects of the pandemic on our loan and
deposit clients. We are focusing on assessing the risks in our loan portfolio
and working with our borrowers to minimize potential loan losses. We have
implemented loan programs to allow borrowers to defer loan principal and
interest payments. See "Working with Borrowers" for more information on loan
deferrals. During 2020, the Company funded 477 PPP loans totaling $80,154,000,
and in 2021, the Company funded 201 PPP loans totaling $25,465,000. At March 31,
2021, there were 368 PPP loans totaling $57,486,000. The reduction in the March
31, 2021 balance represents loan forgiveness or loan paydowns.

Use of Non-GAAP Financial Measures





This Quarterly Report on Form 10-Q ("Form 10Q") contains certain non-GAAP
(Generally Accepted Accounting Principles) financial measures in addition to
results presented in accordance with GAAP.  These measures include the taxable
equivalent basis used in the computation of the net interest margin and
efficiency ratio.  Management has presented these non-GAAP financial measures in
this Form 10Q because it believes that they provide useful and comparative
information to assess trends in the Company's financial position reflected in
the current quarter and year-to-date results and facilitate comparison of our
performance with the performance of our peers.

30




Net Interest Margin and Efficiency Ratio (non-GAAP financial measures)





In accordance with industry standards, certain designated net interest income
amounts are presented on a taxable equivalent basis, including the calculation
of net interest margin and the efficiency ratio.  The Company believes the
presentation of net interest margin on a taxable equivalent basis using a 21%
effective tax rate allows comparability of net interest margin with industry
peers by eliminating the effect of the differences in portfolios attributable to
the proportion represented by both taxable and tax-exempt loans and investments.
The efficiency ratio is a measure of a banking company's overhead as a
percentage of its revenue. The Company derives this ratio by dividing total
noninterest expense by the sum of the taxable equivalent net interest income and
the total noninterest income.

Critical Accounting Policies

General

The Company's financial statements are prepared in accordance with accounting
principles generally accepted in the United States of America ("GAAP"). The
financial information contained within our statements is, to a significant
extent, financial information that is based on measures of the financial effects
of transactions and events that have already occurred. We use historical loss
data and the economic environment as factors, among others, in determining the
inherent loss that may be present in our loan portfolio. Actual losses could
differ significantly from the factors that we use. In addition, GAAP itself may
change from one previously acceptable method to another method. Although the
economics of our transactions would be the same, the timing of events that would
impact our transactions could change.

Allowance for Loan Losses



The allowance for loan losses is an estimate of probable credit losses inherent
in the Company's credit portfolio that have been incurred as of the
balance-sheet date. The allowance is based on two basic principles of
accounting: (1) "Accounting for Contingencies," which requires that losses be
accrued when it is probable that a loss has occurred at the balance sheet date
and such loss can be reasonably estimated; and (2) the "Receivables" topic,
which requires that losses be accrued on impaired loans based on the differences
between the value of collateral, present value of future cash flows or values
that are observable in the secondary market and the loan balance.

31





The allowance for loan losses is determined based upon estimates that can and do
change when the actual risk, loss events, or changes in other factors, occur.
The analysis of the allowance uses a historical loss view as an indicator of
future losses and as a result could differ from the actual losses incurred in
the future. Although management believes the allowance to be adequate, ultimate
losses may vary from its estimates. At least quarterly, the Board of Directors
reviews the adequacy of the allowance, including consideration of the relative
risks in the portfolio, current economic conditions and other factors. If the
Board of Directors and management determine that changes are warranted based on
those reviews, the allowance is adjusted. For further information regarding our
allowance for loan losses, see "Allowance for Loan Losses Activity."



General Development of Business



The Company is a bank holding company registered under the Bank Holding Company
Act of 1956, as amended. The Company was incorporated under the laws of the
State of California in 1995. As a bank holding company, the Company is
authorized to engage in the activities permitted under the Bank Holding Company
Act of 1956, as amended, and regulations thereunder. Its principal office is
located at 3100 Zinfandel Drive, Suite 450, Rancho Cordova, California 95670 and
its telephone number is (916) 854-0123. The Company employed an equivalent of 95
full-time employees as of March 31, 2021.

The Company owns 100% of the issued and outstanding common shares of its banking
subsidiary, American River Bank (the "Bank"), and American River Financial, a
California corporation which has been inactive since its incorporation in 2003.

American River Bank was incorporated and commenced business in Fair Oaks,
California, in 1983 and thereafter moved its headquarters to Sacramento,
California in 1985. American River Bank operates five full service offices in
Sacramento and Placer Counties including the main office located at 1545 River
Park Drive, Suite 107, Sacramento and branch offices in Sacramento, Gold River,
and Roseville; two full service offices in Sonoma County in Healdsburg and Santa
Rosa; and three full service offices in Amador County in Jackson, Pioneer,

and
Ione.



The Bank's deposits are insured by the Federal Deposit Insurance Corporation
(the "FDIC") up to applicable legal limits. American River Bank does not offer
trust services or international banking services and does not plan to do so in
the near future. American River Bank's primary business is serving the
commercial banking needs of small to mid-sized businesses within those counties
listed above. American River Bank accepts checking and savings deposits, offers
money market deposit accounts and certificates of deposit, makes secured and
unsecured commercial, secured real estate, and other installment and term loans
and offers other customary banking services. American River Bank owns 100% of
two inactive companies, ARBCO and American River Mortgage. ARBCO was formed in
1984 to conduct real estate development and has been inactive since 1995.
American River Mortgage has been inactive since its formation in 1994. During
2021 and 2020, the Company conducted no significant activities other than
holding the shares of its subsidiaries. However, it is authorized, with the
prior approval of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), the Company's principal regulator, to engage in a
variety of activities which are deemed closely related to the business of
banking. The common stock of the Company is registered under the Securities
Exchange Act of 1934, as amended, and is listed and traded on the Nasdaq Global
Select Market under the symbol "AMRB."



On April 16, 2021, the Company entered into a Merger Agreement that, upon the
terms and subject to the conditions set forth therein, the Company will merge
with and into Marin Bancorp as described above.

Net Interest Income and Net Interest Margin



Net interest income represents the excess of interest and fees earned on
interest earning assets (loans, securities, Federal funds sold and investments
in time deposits) over the interest paid on interest-bearing deposits and
borrowed funds. Net interest margin is net interest income expressed as a
percentage of average earning assets. The Company's net interest margin was
3.58% for the three months ended March 31, 2021 and 3.75% for the three months
ended March 31, 2020.

The fully taxable equivalent interest income component for the first quarter of
2021 increased $630,000 (9.3%) to $7,401,000 compared to $6,771,000 for the
three months ended March 31, 2020. The increase in the fully taxable equivalent
interest income for the first quarter of 2021 compared to the same period in
2020 is broken down by rate (down $762,000) and volume (up $1,392,000). The
primary driver in this rate decrease was a decrease in the yield on loans, which
led to a decrease of $174,000, a decrease in the yield on investments, which led
to a decrease of $476,000, and a decrease in the yield on interest-bearing
deposits in banks, which led to a decrease of $112,000. The yield on loans
decreased from 5.03% in the first three months of 2020 to a yield of 4.92%
during the first three months of 2021; the yield on investments decreased from
2.69% in the first three months of 2020 to a yield of 2.06% during the first
three months of 2021 and the yield on interest-bearing deposits in banks
decreased from 1.59% in the first quarter of 2020 to 0.11% in the first quarter
of 2021. The volume increase of $1,392,000 was primarily from an increase in
loans ($1,059,000); an increase in investments ($248,000); and an increase in
interest-bearing deposits in banks ($86,000). Average loans balances increased
$84,889,000, (or 21.4%), from $396,322,000 during the first quarter of 2020 to
$481,211,000 during the first quarter of 2021; average investment balances
increased $37,401,000, (or 14.1%), from $265,037,000 during the first quarter of
2020 to $302,438,000 during the first quarter of 2021, and average balances in
interest-bearing deposits in banks increased $22,016,000, (or 255.6%), from
$8,615,000 during the first quarter of 2020 to $30,631,000 during the first

quarter of 2021.

Interest expense was $222,000 or $305,000 (57.9%) lower in the first quarter of
2021 compared to $527,000 in the first quarter of 2020. The net $305,000
decrease in interest expense during the first quarter of 2021 compared to the
first quarter of 2020 was predominantly rate related which reduced expense by
$369,000. This decrease was partially offset by volume which increased expense
by $64,000. Rates paid on interest bearing liabilities decreased 34 basis points
from 0.54% to 0.20% for the first quarter of 2020 compared to the first quarter
of 2021. Of the $369,000 decrease in interest expense related to rates, $175,000
is related to lower rates paid on interest checking and money market accounts
and $147,000 was related to time deposit balances. The overall lower interest
rate environment in short term rates contributed to this decrease in interest
expense. Partially offsetting the decrease in expense due to rates was an
increase due to volume as average interest bearing balances increased
$60,515,000 (15.4%) from $392,517,000 in the first quarter of 2020 to
$453,032,000 during the first quarter of 2021.

Provision for Loan Losses



The Company did not provide a provision for loan losses in the first quarter of
2021 compared to $495,000 in the first quarter of 2020. The Company experienced
net loan recoveries of $68,000 or (0.06%) (on an annualized basis) of average
loans for the three months ended March 31, 2021 compared to net loan recoveries
of $4,000 or (0.00%) (on an annualized basis) of average loans for the three
months ended March 31, 2020. The Company continues to experience an overall
improvement in the credit quality of the loan portfolio and a reduction of
credit losses, however, due to the uncertain economic impact on the Company's
borrowers due to COVID-19, the $495,000 addition in 2020 to the provision for
loan losses during the first quarter of 2020 was warranted. For additional
information see the "Allowance for Loan Losses Activity" and "Potential Impact
of COVID-19." The net loan recoveries, reduction in loan balances in the first
quarter of 2021, and the progress made in the circulation of the pandemic
vaccine allowed the Company to forgo and additions to the provision for loan
losses in the first quarter of 2021

Noninterest Income

Table Four below provides a summary of the components of noninterest income for the periods indicated (dollars in thousands):

Service charges on deposit accounts            $     164       $     155
Gain on sale of securities                           172              38

Total noninterest income                       $     591       $     452




Noninterest income increased $139,000 (30.8%) to $591,000 for the three months
ended March 31, 2021 as compared to $452,000 for the three months ended March
31, 2020. The increase in noninterest income was primarily related to higher
gain on sale of securities, which increased $134,000 (352.6%) from $38,000

in
2020 to $172,000 in 2021.



Noninterest Expense

Noninterest expense decreased $153,000 (3.6%) to a total of $4,063,000 in the
first quarter of 2021 compared to $4,216,000 in the first quarter of 2020.
Salary and employee benefits expense decreased $103,000 (3.6%) from $2,865,000
during the first quarter of 2020 to $2,762,000 during the first quarter of 2021.
The decrease in salaries and benefits expense resulted from an increase in the
deferral of direct loan origination costs, which reduced salary expense. Each
PPP loan that was recorded had an associated loan origination cost. Total
origination costs for the first quarter of 2021 were $212,000 compared to
$82,000 for the first quarter of 2020. Of the $212,000 in deferred loan
origination costs recorded in 2021, $140,700 was related to PPP loans. The
benefit from the deferred loan origination costs was partially offset by normal
cost of living increases and promotions. Average full-time equivalent employees
was 95 during the first quarter of 2021 compared to 101 during the first quarter
of 2020.

On a quarter-over-quarter basis, occupancy expense increased $3,000 (1.2%) and
furniture and equipment expense decreased $9,000 (6.3%). FDIC assessments
increased $27,000 (100.0%) from the first quarter of 2020 to the first quarter
of 2021. The increased FDIC assessments result from the FDIC insurance fund
reaching the target of 1.38% and the Company being able to use the Small Bank
Assessment Credits, awarded to banks like American River Bank, which essentially
gave banks a credit for the assessments paid in the latter half of 2019 and for
a partial amount of the expense for the first quarter of 2020. There were no
assessment credits received in the first quarter of 2021. OREO related expenses
decreased $1,000 (20.0%) from $5,000 in the first quarter of 2020 to $4,000 in
the first quarter of 2021. Other expense decreased $70,000 (7.6%) from $920,000
in the first quarter of 2020 to $850,000 in the first quarter of 2021. There
were numerous line items that make up the $70,000 decrease in other expenses
including a $21,000 (131.3%) decrease in business development, which decreased
from $37,000 in 2020 to $16,000 in 2021, and a $16,000 (40.0%) decrease in legal
fees, which decreased from $40,000 in 2020 to $24,000 in 2021. The fully taxable
equivalent efficiency ratio decreased from 63.0% for the first quarter of 2020
to 52.3% for the first quarter of 2021.

Provision for Income Taxes





Federal and state income taxes for the quarter ended March 31, 2021 increased
$516,000 (103.8%) from $497,000 in the first quarter of 2020 to $1,013,000 in
the first quarter of 2021. The effective tax rate for the quarter ended March
31, 2021 was 27.7% compared to 25.8% for the first quarter of 2020. The higher
tax expense was related to the higher level of taxable income ($1,731,000 or
89.7%), which increased from $1,929,000 in 2020 to $3,660,000 in 2021. The
higher effective tax rate in 2021 compared to 2020 is also related to the higher
level of taxable income as well as a lower level of benefits from tax-exempt
loans and investments (including investments in bank owned life insurance).
Tax-exempt benefits decreased from $346,000 in 2020 to $296,000 in 2021.

Balance Sheet Analysis


The Company's total assets were $916,063,000 at March 31, 2021 as compared to
$868,991,000 at December 31, 2021, representing an increase of $47,072,000
(5.4%). The average assets for the three months ended March 31, 2021 were
$884,565,000, which represents an increase of $163,126,000 or 22.6% over the
balance of $721,439,000 during the three-month period ended March 31, 2020.

Cash and Cash Equivalents

The balance held in cash and cash equivalents at March 31, 2021, was $97,798,000
compared to $42,509,000 at December 31, 2020 an increase of $55,289,000
(130.1%). The primary reason for the increase in cash and cash equivalents since
December 31, 2020 is directly related to the increase in deposit balances during
the same period.

The Company classifies its investment securities as available-for-sale or
held-to-maturity. The Company's intent is to hold all securities classified as
held-to-maturity until maturity and management believes that it has the ability
to do so. Securities available-for-sale may be sold to implement asset/liability
management strategies and in response to changes in interest rates, prepayment
rates and similar factors. Net unrealized gains on available-for-sale investment
securities totaling $5,133,000 were recorded, net of $1,517,000 in tax
liabilities, as accumulated other comprehensive loss within shareholders' equity
at March 31, 2021 and net unrealized gains on available-for-sale investment
securities totaling $8,739,000 were recorded, net of $2,583,000 in tax
liabilities, as accumulated other comprehensive loss within shareholders' equity
at December 31, 2020.



Management periodically evaluates each investment security in a loss position
for other than temporary impairment relying primarily on industry analyst
reports, observation of market conditions and interest rate fluctuations.
Management has the ability and intent to hold securities with established
maturity dates until recovery of fair value, which may be until maturity, and
believes it will be able to collect all amounts due according to the contractual
terms for all of the underlying investment securities; therefore, management
does not consider these investments to be other-than-temporarily impaired.

Loans



The Company's historical lending activities have been in the following principal
areas: (1) commercial; (2) commercial real estate; (3) multi-family real estate;
(4) real estate construction (both commercial and residential); (5) residential
real estate; (6) agriculture; and (7) consumer loans. The Company's continuing
focus in our market area, new borrowers developed through the Company's
marketing efforts, and credit extensions expanded to existing borrowers resulted
in the Company originating $25.9 million in new loans during the first quarter
of 2021. In addition to the $25.9 million in new production the Company also
originated 201 PPP loans totaling $25.5 million during the first quarter of
2021. This production was partially offset by pay downs and payoffs, and
excluding the PPP loans resulted in an overall decrease in net loans of
$4,702,000 (1.1%) from December 31, 2020. At March 31, 2021, gross PPP loans
were $57,486,000 and had related fees of $1,354,000, for a net balance of
$56,132,000. These PPP loans were recorded as commercial loans. At March 31,
2021, net loans excluding net PPP loans were $419,282,000 and total loans
excluding total PPP loans were $420,030,000.

37





A significant portion of the Company's loans are direct loans made to
individuals and local businesses. The Company relies substantially on
networking, local promotional activity, and personal contacts by American River
Bank officers, directors and employees to compete with other financial
institutions. The Company makes loans to borrowers whose applications include a
sound purpose and a viable primary repayment source, generally supported by a
secondary source of repayment. Commercial loans consist of credit lines for
operating needs, loans for equipment purchases, working capital, and various
other business loan products. Consumer loans include a range of traditional
consumer loan products such as personal lines of credit and homeowner equity
lines of credit and loans to finance purchases of autos (including classic and
collectors autos), boats, recreational vehicles, mobile homes and various other
consumer items. Construction loans are generally comprised of commitments to
customers within the Company's service area for construction of commercial
properties, multi-family properties and custom and semi-custom single-family
residences. Other real estate loans consist primarily of loans secured by first
trust deeds on commercial, multi-family, and residential properties typically
with maturities from three to ten years and original loan-to-value ratios
generally from 65% to 75%. Agriculture loans consist primarily of first trust
deed loans on properties that produce grapes, fruit, and nut loans. In general,
except in the case of loans under SBA programs or Farm Services Agency
guarantees, the Company does not make long-term residential mortgage loans.

Risk Elements

The Company assesses and manages credit risk on an ongoing basis through a total
credit culture that emphasizes excellent credit quality, extensive internal
monitoring and established formal lending policies. Additionally, the Company
contracts with an outside loan review consultant to periodically review the
existing loan portfolio. Management believes its ability to identify and assess
risk and return characteristics of the Company's loan portfolio is critical for
profitability and growth. Management strives to continue its emphasis on credit
quality in the loan approval process, through active credit administration and
regular monitoring. With this in mind, management has designed and implemented a
comprehensive loan review and grading system that functions to continually
assess the credit risk inherent in the loan portfolio.

38





Ultimately, underlying trends in economic and business cycles influence credit
quality. American River Bank's business is concentrated in the Sacramento
Metropolitan Statistical Area, which is a diversified economy, but with a large
State of California government presence and employment base; in Sonoma County,
which is focused on businesses within the two communities in which the Bank has
offices (Santa Rosa and Healdsburg); and in Amador County, in which the Bank is
primarily focused on businesses within the three communities in which it has
offices (Jackson, Pioneer, and Ione). The economy of Sonoma County is
diversified with professional services, manufacturing, agriculture and real
estate investment and construction, while the economy of Amador County is
reliant upon government, services, retail trade, manufacturing industries and
Indian gaming.

The Company has significant extensions of credit and commitments to extend
credit that are secured by real estate. The ultimate repayment of these loans is
generally dependent on personal or business cash flows or the sale or
refinancing of the real estate. The Company monitors the effects of current and
expected market conditions and other factors on the collectability of real
estate loans. The more significant factors management considers involve the
following: lease rates and terms, vacancy rates, absorption and sale rates and
capitalization rates; real estate values, supply and demand factors, and rates
of return; operating expenses; inflation and deflation; and sufficiency of
repayment sources independent of the real estate including, in some instances,
personal guarantees.

In extending credit and commitments to borrowers, the Company generally requires
collateral and/or guarantees as security. The repayment of such loans is
expected to come from cash flows or from proceeds from the sale of selected
assets of the borrowers. The Company's requirement for collateral and/or
guarantees is determined on a case-by-case basis in connection with management's
evaluation of the creditworthiness of the borrower. Collateral held varies but
may include accounts receivable, inventory, property, plant and equipment,
income-producing properties, residences and other real property. The Company
secures its collateral by perfecting its security interest in business assets,
obtaining deeds of trust, or outright possession among other means.



In management's judgment, a concentration exists in real estate loans, which
represented approximately 84% of the Company's loan portfolio at March 31, 2021
and 83% as of December 31, 2020. These figures exclude the PPP loans, which are
100% guaranteed by the SBA. Management believes that the residential land and
construction portion of the Company's loan portfolio carries a reasonable level
of credit risk.  As of March 31, 2021, outstanding unimproved residential land
and construction loans were $8,342,000 (or just 2.4% of the total real estate
loans). Management currently believes that it maintains its allowance for loan
losses at levels adequate to reflect the loss risk inherent in its total loan
portfolio.



A decline in the economy in general, or decline in real estate values in the
Company's market areas, in particular, could have an adverse impact on the
collectability of real estate loans and require an increase in the provision for
loan losses. This could adversely affect the Company's future prospects, results
of operations, profitability and stock price. See "Potential Impact of
COVID-19." Management believes that its lending practices and underwriting
standards are structured with the intent to minimize losses; however, there is
no assurance that losses will not occur. The Company's loan practices and
underwriting standards include, but are not limited to, the following
principles: (1) maintaining a thorough understanding of the Company's market
area and originating a significant majority of its loans within that area, (2)
maintaining a thorough understanding of borrowers' knowledge, capacity, and
market position in their field of expertise, (3) basing real estate loan
approvals not only on market demand for the project, but also on the borrowers'
capacity to support the project financially in the event it does not perform to
expectations (whether sale or income performance), and (4) maintaining
conforming and prudent loan-to-value and loan-to-cost ratios based on
independent outside appraisals and ongoing inspection and analysis by the
Company's lending officers or contracted third-party professionals.



Nonperforming, Past Due and Restructured Loans


Management places loans on nonaccrual status when they become 90 days past due
or if a loss is expected, unless the loan is well secured and in the process of
collection. Loans are partially or fully charged off when, in the opinion of
management, collection of such amount appears unlikely. The recorded investments
in nonperforming loans, which includes nonaccrual loans and loans that were 90
days or more past due and on accrual, totaled zero at both March 31, 2021 and
December 31, 2020, respectively. At March 31, 2021 and December 31, 2020 there
were no loans that were 30 days or more past due.

39





There were no loan concentrations in excess of 10% of total loans not otherwise
disclosed as a category of loans as of March 31, 2021. Management is not aware
of any potential problem loans, which were accruing and current at March 31,
2021, where serious doubt exists as to the ability of the borrower to comply
with the present repayment terms and that would result in a significant loss to
the Company apart from those loans identified in the Bank's impairment analysis.
Table Seven below sets forth nonaccrual loans and loans past due 90 days or more
as of March 31, 2021 and December 31, 2020.

Impaired Loans

The Company considers a loan to be impaired when, based on current information
and events, it is probable that it will be unable to collect all amounts due
(principal and interest) according to the original contractual terms of the loan
agreement. The measurement of impairment may be based on (i) the present value
of the expected cash flows of the impaired loan discounted at the loan's
original effective interest rate, (ii) the observable market price of the
impaired loan, or (iii) the fair value of the collateral of a
collateral-dependent loan. The Company does not apply this definition to
smaller-balance loans that are collectively evaluated for credit risk. In
assessing whether a loan is impaired, the Company typically reviews loans graded
substandard or lower with outstanding principal balances in excess of $100,000,
as well as loans considered troubled debt restructures with outstanding
principal balances in excess of $25,000. The Company identifies troubled debt
restructures by reviewing each renewal, modification, or extension of a loan
with a screening document.  This document is designed to identify any
characteristics of such a loan that would qualify it as a troubled debt
restructure.  If the characteristics are not present that would qualify a loan
as a troubled debt restructure, it is deemed to be a modification.

At March 31, 2021, the recorded investment in loans that were considered to be
impaired totaled $6,989,000, all of which are considered performing loans. Of
the total impaired loans of $6,989,000, loans totaling $5,357,000 were deemed to
require no specific reserve and loans totaling $1,632,000 were deemed to require
a related valuation allowance of $109,000. Of the $5,357,000 impaired loans that
did not carry a specific reserve there were $461,000 in loans that had previous
partial charge-offs and $4,896,000 in loans that were analyzed and determined
not to require a specific reserve or charge-off because the collateral value or
discounted cash flow value exceeded the loan balance. The recorded investment in
loans that were considered to be impaired totaled $7,050,000 at December 31,
2020. Of the total impaired loans of $7,050,000, loans totaling $5,387,000 were
deemed to require no specific reserve and loans totaling $1,663,000 were deemed
to require a related valuation allowance of $112,000.



Prior to 2013, the Company had been operating in a market that had experienced
significant decreases in real estate values of commercial, residential, land,
and construction properties. As such, the Company is focused on monitoring
collateral values for those loans considered collateral dependent. For
collateral dependent loans the Company performs an internal evaluation or
obtains an updated appraisal, as necessary.  In the first quarter of 2021, the
Company had net loan recoveries of $68,000 with zero provisions for loan losses.
The Company's ALLL to non-PPP loans (which are 100% SBA guaranteed) is 1.60% at
March 31, 2021. The 1.60% ALLL to loans is higher than the Company's historical
average. Despite the Company's continued improvement in the credit quality of
the loan portfolio, due to the uncertain economic impact on the Company's
borrowers due to COVID-19, management believes that the 1.60% ALLL to non-PPP
loans is warranted. In the first quarter of 2020, the Company had net loan
recoveries of $4,000 with $475,000 in added provision.



During the periods ended March 31, 2021 and March 31, 2020, there were no loans
that were modified as troubled debt restructurings. There were no payment
defaults during the three months ended March 31, 2021 or March 31, 2020 on
troubled debt restructurings made in the preceding twelve months. At March 31,
2021 and December 31, 2020, there were no unfunded commitments on those loans
considered troubled debt restructures.

Working with Borrowers



The FDIC is encouraging financial institutions, like American River Bank, to
provide borrowers affected in a variety of ways by the COVID-19 outbreak with
payment accommodations that facilitate their ability to work through the
immediate impact of the virus. Such assistance provided in a prudent manner to
borrowers facing short-term setbacks could help the borrower and our community
to recover. The FDIC indicated that these loan accommodation programs should be
ultimately targeted toward loan repayment, but that if provided in a prudent
manner such programs can help borrowers and communities recover from short-term
setbacks.



The FDIC encouraged financial institutions to consider ways to address any
deferred or skipped payments such as extending the original maturity date or by
making those payments due in a balloon payment at the maturity date of the loan.
The terms of the payment deferrals are generally 90 days and up to 180 days and
borrowers may be eligible for multiple deferrals. Pursuant to the CARES Act,
these loan modifications are not accounted for as troubled debt restructure. As
of June 30, 2020, the Company had made 107 such loan payment deferrals totaling
$96,465,000. During the third quarter 2020, two additional loans totaling
$2,980,000 were extended loan payment deferrals and four loans that had
previously been provided loan payment deferrals totaling $2,123,000 paid off in
full. In addition, during the third quarter 69 loans that had previously been
granted loan payment deferrals began making their loan payments and are no
longer on a loan deferral program. As of September 30, 2020, 39 loans totaling
$39,576,000 were on a loan deferral program and of these loans, four loans
totaling $4,074,000 were in their initial deferral period while 32 loans
totaling $35,502,000 were provided an additional deferral period either after
their initial deferral period ended or prior to the ending of their initial
deferral period. As of December 31, 2020, there were two commercial real estate
loans totaling $4,882,000 that had been granted loan payment deferrals. These
two loans resumed their contractual payments during the first quarter of 2021.
Also during the first quarter of 2021, one additional loan in the amount of
$2,017,000 was granted a 90-day interest only payment deferral. This was the
only loan on payment deferral at March 31, 2021, however, this borrower resumed
making the contractual payment during the second quarter of 2021. These loans
are not considered past due until after the deferral period is over and
scheduled payments have resumed and any subsequently scheduled payments are
missed.

The Company continues to accrue interest on all of the loan deferrals. The
Company expects to continue to work with its borrowers and make prudent credit
arrangements as needed, while intending to continue to act in a safe and sound
manner. The Company has continued to keep in close contact with the borrowers
that have been granted loan payment deferrals and continued to monitor those
loans that have begun making their loan payments to track their payment history
and evaluate whether it is appropriate to upgrade or downgrade the individual
loan ratings. None of the borrowers that had been granted loan deferrals were
more than 30 days past due immediately preceding the deferral date, and for
those that have resumed making payments, none are more than 30 days past due at
March 31, 2021.


Allowance for Loan Losses Activity



The Company maintains an allowance for loan losses ("ALLL") to cover probable
losses inherent in the loan portfolio, which is based upon management's estimate
of those losses. The ALLL is established through a provision for loan losses and
is increased by provisions charged against current earnings and recoveries and
reduced by charge-offs. Actual losses for loans can vary significantly from this
estimate. The methodology and assumptions used to calculate the allowance are
continually reviewed as to their appropriateness given the most recent losses
realized and other factors that influence the estimation process. The model
assumptions and resulting allowance level are adjusted accordingly as these
factors change.

The adequacy of the ALLL and the level of the related provision for loan losses
is determined based on management's judgment after consideration of numerous
factors including, but not limited to: (i) local and regional economic
conditions, (ii) the financial condition of the borrowers, (iii) loan impairment
and the related level of expected charge-offs, (iv) evaluation of industry
trends, (v) industry and other concentrations, (vi) loans which are
contractually current as to payment terms but demonstrate a higher degree of
risk as identified by management, (vii) continuing evaluations of the performing
loan portfolio, (viii) ongoing review and evaluation of problem loans identified
as having loss potential, (ix) quarterly review by the Board of Directors, and
(x) assessments by banking regulators and other third parties. Management and
the Board of Directors evaluate the ALLL and determine its appropriate level
considering objective and subjective measures, such as knowledge of the
borrower's business, valuation of collateral, the determination of impaired
loans and exposure to potential losses.

The ALLL totaled $6,696,000 or 1.41% of total loans at March 31, 2021 compared
to $6,628,000 or 1.39% of total loans at December 31, 2020. Excluding the 100%
SBA guaranteed PPP loans, which do not carry the same risk as the rest of the
loan portfolio, the ALLL to total loans was 1.60% at March 31, 2021 and 1.56% at
December 31, 2020. The allowance for loans as a percentage of impaired loans was
95.8% at March 31, 2021 and 94.0% at December 31, 2020. The Company establishes
general and specific reserves in accordance with accounting principles generally
accepted in the United States of America. The ALLL is composed of categories of
the loan portfolio based on loan type and loan rating; however, the entire
allowance is available to cover actual loan losses. While management uses
available information to recognize possible losses on loans, future additions to
the allowance may be necessary, based on changes in economic conditions and
other matters. In addition, various regulatory agencies, as an integral part of
their examination process, periodically review the Company's ALLL. Such agencies
may require the Company to provide additions to the allowance based on their
judgment of information available to them at the time of their examination.

The Company's policy with regard to loan charge-offs continues to be that a loan
is charged off against the ALLL when management believes that the collectability
of the principal is unlikely. As previously discussed in the "Impaired Loans"
section, certain loans are evaluated for impairment. Generally, if a loan is
collateralized by real estate or other collateral, and considered collateral
dependent, the impaired portion will be charged off to the allowance for loan
losses unless it is in the process of collection, in which case a specific
reserve may be warranted. Table Eight below summarizes, for the periods
indicated, the activity in the ALLL.

It is the policy of management to maintain the allowance for loan losses at a
level believed to be adequate for known and inherent risks in the portfolio. Our
methodology incorporates a variety of risk considerations, both quantitative and
qualitative, in establishing an allowance for loan losses that management
believes is appropriate at each reporting date. Formula allocations are
calculated by applying historical loss factors to outstanding loans with similar
characteristics.  Historical loss factors are based upon the Company's loss
experience. These historical loss factors are adjusted for changes in the
business cycle and for significant factors that, in management's judgment,
affect the collectability of the loan portfolio as of the evaluation date. The
discretionary allocation is based upon management's evaluation of various loan
segment conditions that are not directly measured in the determination of the
formula and specific allowances.  The conditions may include, but are not
limited to, general economic and business conditions affecting the key lending
areas of the Company, credit quality trends, collateral values, loan volumes and
concentrations, and other business conditions. Based on information currently
available, management believes that the allowance for loan losses is prudent and
adequate. However, no prediction of the ultimate level of loans charged off in
future periods can be made with any certainty.



Other Real Estate Owned



At March 31, 2021 and December 31, 2020, the Company had one other real estate
owned ("OREO") property totaling $800,000. During the first quarter of 2021, the
Company did not acquire or sell any OREO properties nor were there any
impairment charges to this property. There was no valuation allowance at March
31, 2021 nor at year-end 2020. The Company believes that the OREO property owned
at March 31, 2021 was carried approximately at fair value.

Deposits



At March 31, 2021, total deposits were $788,569,000 representing a $44,392,000
(6.0%) increase from the December 31, 2020 balance of $744,177,000. The
Company's deposit growth plan for 2021 is to concentrate its efforts on
increasing noninterest-bearing demand, interest-bearing money market and NOW
accounts, and savings accounts while continuing to focus on maintaining an
overall lower cost of funds than our peer group, while at the same time
retaining our high-valued deposit relationships. During the first quarter of
2021, the Company experienced increases in noninterest-bearing checking
($9,619,000 or 2.9%), interest-bearing checking ($12,081,000 or 14.7%), money
market savings ($10,545,000 or 6.0%), savings ($6,307,000 or 7.2%), and time
deposits ($5,840,000 or 8.4%). Some of the deposit increase can be attributed to
our business accounts depositing the funds received from their PPP loans into
their accounts held at American River Bank, as well as, balance increases due to
the deferral payroll tax payments and other government programs.

Other Borrowed Funds



Other borrowings outstanding as of March 31, 2021 and December 31, 2020, consist
of advances (both short-term and long-term) from the Federal Home Loan Bank of
San Francisco ("FHLB"). Table Nine below summarizes these borrowings.

The maximum amount of short-term borrowings at any month-end during the first
three months of 2021 and 2020 was $7,000,000 and $12,000,000, respectively. The
FHLB advances are collateralized by loans and securities pledged to the FHLB.
The following is a breakdown of rates and maturities on FHLB advances (dollars

Capital Resources



The Company and American River Bank are subject to certain regulatory capital
requirements administered by the Board of Governors of the Federal Reserve
System and the Federal Deposit Insurance Corporation (the "FDIC"). Failure to
meet these minimum capital requirements can initiate certain mandatory, and
possibly additional discretionary, actions by regulators that, if undertaken,
could have a direct material effect on the Company's consolidated financial
statements. Under capital adequacy guidelines and the regulatory framework for
prompt corrective action, banks must meet specific capital guidelines that
involve quantitative measures of their assets, liabilities and certain
off-balance-sheet items as calculated under regulatory accounting practices. The
Company's and American River Bank's capital amounts and classification are also
subject to qualitative judgments by the regulators about components, risk
weightings and other factors.



At March 31, 2021, shareholders' equity was $92,891,000, representing a decrease
of $204,000 (0.2%) from $93,095,000 at December 31, 2020. The decrease results
from net income for the period ($2,647,000), stock based compensation and stock
options exercised ($105,000), being less than decrease from other comprehensive
income ($2,540,000) and the payment of cash dividends ($416,000). Table Ten
below lists the Company's and American River Bank's capital ratios at March 31,
2021 and December 31, 2020, as well as the minimum capital ratios for capital
adequacy and the minimum requirement for a well-capitalized institution. While
the Company has elected to adopt the community bank leverage ratio framework in
which it is no longer required to report the risk-based capital ratios, we
believe reporting them to our shareholders allows them to compare the ratios of
companies of similar size and, therefore, are presented below.

On February 17, 2021, the Company paid a $0.07 per common share cash dividend to
shareholders of record on February 3, 2021. This 2021 quarterly dividend follows
four quarterly cash dividends, totaling $0.28 per share, paid in 2020. Capital
ratios are reviewed on a regular basis to ensure that capital exceeds the
prescribed regulatory requirements and is adequate to meet future needs.
Accordingly, we cannot provide any assurance that we will continue to pay cash
dividends at the same historical rates, or at all. Management believes that both
the Company and American River Bank met all of their capital adequacy
requirements as of March 31, 2021 and December 31, 2020.



The Bank's capital requirements consist of the following: (i) a common equity
Tier 1 capital to total risk weighted assets ratio of 4.5%; (ii) a Tier 1
capital to total risk weighted assets ratio of 6%; (iii) a total capital to
total risk weighted assets ratio of 8%; and (iv) a Tier 1 capital to adjusted
average total assets ("leverage") ratio of 4%.

44





In addition, a "capital conservation buffer," was established which requires
maintenance of a minimum of 2.5% of common equity Tier 1 capital to total risk
weighted assets in excess of the regulatory minimum capital ratio requirements
described above. The 2.5% buffer increases the minimum capital ratios to (i) a
common equity Tier 1 capital ratio of 7.0%, (ii) a Tier 1 capital ratio of 8.5%,
and (iii) a total capital ratio of 10.5%. The buffer requirement became fully
phased in on January 1, 2019. If the capital ratio levels of a banking
organization fall below the capital conservation buffer amount, the organization
will be subject to limitations on (i) the payment of dividends; (ii)
discretionary bonus payments; (iii) discretionary payments under Tier 1
instruments; and (iv) engaging in share repurchases.

Inflation



The impact of inflation on a financial institution differs significantly from
that exerted on manufacturing or other commercial concerns primarily because its
assets and liabilities are largely monetary. In general, inflation primarily
affects the Company and its subsidiaries through its effect on market rates of
interest, which affects the Company's ability to attract loan customers.
Inflation affects the growth of total assets by increasing the level of loan
demand and potentially adversely affects capital adequacy because loan growth in
inflationary periods can increase at rates higher than the rate that capital
grows through retention of earnings which may be generated in the future. In
addition to its effects on interest rates, inflation increases overall operating
expenses. Inflation has not had a significant effect upon the results of
operations of the Company and its subsidiaries during the periods ended March
31, 2021 and 2020.

Liquidity

Liquidity management refers to the Company's ability to provide funds on an
ongoing basis to meet fluctuations in deposit levels as well as the credit needs
and requirements of its clients. Both assets and liabilities contribute to the
Company's liquidity position. Federal funds lines, short-term investments and
securities, and loan repayments contribute to liquidity, along with deposit
increases, while loan funding and deposit withdrawals decrease liquidity. The
Company assesses the likelihood of projected funding requirements by reviewing
historical funding patterns, current and forecasted economic conditions and
individual client funding needs. Commitments to fund loans and outstanding
standby letters of credit at March 31, 2021 were approximately $43,649,000 and
$60,000, respectively. Such loan commitments relate primarily to revolving lines
of credit and other commercial loans and to real estate construction loans.
Since some of the commitments are expected to expire without being drawn upon,
the total commitment amounts do not necessarily represent future cash
requirements.

The Company's sources of liquidity consist of cash and due from correspondent
banks, overnight funds sold to correspondent banks, unpledged marketable
investments and loans held for sale and/or pledged for secured borrowings. At
March 31, 2021, consolidated liquid assets totaled $220.1 million or 24.0% of
total assets compared to $191.2 million or 22.0% of total assets on December 31,
2020. In addition to liquid assets, the Company maintains two short-term
unsecured lines of credit in the amount of $17,000,000 with two of its
correspondent banks. At March 31, 2021, the Company had $17,000,000 available
under these credit lines. Additionally, the Bank is a member of the FHLB. At
March 31, 2021, the Bank could have arranged for up to $172,836,000 in secured
borrowings from the FHLB. These borrowings are secured by pledged mortgage loans
and investment securities. At March 31, 2021, the Company had advances,
borrowings and commitments (including letters of credit) outstanding of
$20,787,000, leaving $152,049,000 available under these FHLB secured borrowing
arrangements. American River Bank also has a secured borrowing arrangement with
the Federal Reserve Bank of San Francisco. The borrowing can be secured by
pledging selected loans and investment securities. At March 31, 2021, the
Company's borrowing capacity at the Federal Reserve Bank was $6,062,000. The
Company serves primarily a business and professional customer base and, as such,
its deposit base is susceptible to economic fluctuations. Accordingly,
management strives to maintain a balanced position of liquid assets and
borrowing capacity to offset the potential runoff of these volatile and/or
cyclical deposits.

Liquidity is also affected by portfolio maturities and the effect of interest
rate fluctuations on the marketability of both assets and liabilities. The
Company can sell any of its unpledged securities held in the available-for-sale
category to meet liquidity needs. Furthermore, the Bank can pledge additional
unencumbered securities to borrow from the Federal Reserve Bank of San Francisco
and the FHLB.

45





Off-Balance Sheet Items

The Company is a party to financial instruments with off-balance-sheet risk in
the normal course of business in order to meet the financing needs of its
customers and to reduce its exposure to fluctuations in interest rates. These
financial instruments consist of commitments to extend credit and letters of
credit. These instruments involve, to varying degrees, elements of credit and
interest rate risk in excess of the amount recognized on the balance sheet.

The Company's exposure to credit loss in the event of nonperformance by the
other party for commitments to extend credit and letters of credit is
represented by the contractual amount of those instruments. The Company applies
the same credit policies to commitments and letters of credit as it does for
loans included on the consolidated balance sheet. As of March 31, 2021 and
December 31, 2020, commitments to extend credit and standby letters of credit
were the only financial instruments with off-balance sheet risk. The Company has
not entered into any contracts for financial derivative instruments such as
futures, swaps, options or similar instruments. Loan commitments and standby
letters of credit were $43,709,000 and $32,851,000 at March 31, 2021 and
December 31, 2020, respectively. As a percentage of net loans these off-balance
sheet items represent 9.3% and 7.0%, respectively.
