NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2019

1. CONSOLIDATED FINANCIAL STATEMENTS

In the opinion of management, the unaudited consolidated financial statements contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the consolidated financial position of American River Bankshares (the “Company”) at March 31, 2019 and December 31, 2018, the results of its operations and its cash flows for the three-month periods ended March 31, 2019 and 2018 in conformity with accounting principles generally accepted in the United States of America.

Certain disclosures normally presented in the notes to the annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted. The Company believes that the disclosures are adequate to make the information not misleading. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2018. The results of operations for the three-month period ended March 31, 2019 may not necessarily be indicative of the operating results for the full year.

In preparing such financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ significantly from those estimates.

Management has determined that since all of the banking products and services offered by the Company are available in each branch office of American River Bank, all branch offices are located within the same economic environment and management does not allocate resources based on the performance of different lending or transaction activities, it is appropriate to aggregate all of the branch offices and report them as a single operating segment. No client accounts for more than ten percent (10%) of revenues for the Company or American River Bank.

Adoption of New Accounting Standard: On January 1, 2019, the Company adopted ASU No. 2016-02, “ Leases ”, utilizing the effective date method under the modified retrospective approach. The Company currently leases nine of its office leases under operating leases. The Company’s present value of future lease payments as of January 1, 2019 was $3,570,000 which was recorded as a right-of-use asset included in accrued interest receivable and other assets with an offsetting liability included in accrued interest payable and other liabilities on the consolidated balance sheet. The effects of adopting ASU No. 2016-02 did not have a material impact on the Company’s financial position, results of operations or cash flows.

2. STOCK-BASED COMPENSATION

Equity Plans

On March 17, 2010, the Board of Directors adopted the 2010 Equity Incentive Plan (the “2010 Plan”). The 2010 Plan was approved by the Company’s shareholders on May 20, 2010. In 2000, the Board of Directors adopted and the Company’s shareholders approved a stock option plan (the “2000 Plan”). There were 11,140 stock options outstanding at December 31, 2018, all of which were exercised during the first quarter of 2019; accordingly, there are no further grants outstanding under the 2000 Plan. At March 31, 2019, there were 29,958 stock options and 47,058 restricted shares outstanding and the total number of authorized shares that remain available for issuance under the 2010 Plan was 1,283,232. The 2010 Plan provides for the following types of stock-based awards: incentive stock options; nonqualified stock options; stock appreciation rights; restricted stock; restricted performance stock; unrestricted Company stock; and performance units. Under the 2010 Plan, the awards may be granted to employees and directors under incentive and nonqualified option agreements, restricted stock agreements, and other awards agreements. The 2010 Plan requires that the option price may not be less than the fair market value of the stock at the date the option is awarded. The option awards under the 2010 Plan expire on dates determined by the Board of Directors, but not later than ten years from the date of award. The vesting period is generally five years; however, the vesting period can be modified at the discretion of the Company’s Board of Directors. Outstanding option awards under the 2010 Plan are exercisable until their expiration. New shares are issued upon exercise of an option.

The award date fair value of awards is determined by the market price of the Company’s common stock on the date of award and is recognized ratably as compensation expense or director expense over the vesting periods. The shares of common stock awarded pursuant to such agreements vest in increments over one to five years from the date of award. The shares awarded to employees and directors under the restricted stock agreements vest on the applicable vesting dates only to the extent the recipient of the shares is then an employee or a director of the Company or one of its subsidiaries, and each recipient will forfeit all of the shares that have not vested on the date his or her employment or service is terminated.

Equity Compensation

For the three-month periods ended March 31, 2019 and 2018, the compensation cost recognized for equity compensation was $83,000 and $73,000, respectively. The recognized tax benefit for equity compensation expense was $21,000 and $18,000, for the three-month periods ended March 31, 2019 and 2018, respectively.

At March 31, 2019, the total compensation cost related to nonvested stock option awards not yet recorded is $13,000. This amount will be recognized over the next 1.3 years and the weighted average period of recognizing these costs is expected to be 0.6 years. At March 31, 2019, the total compensation cost related to restricted stock awards not yet recorded is $497,000. This amount will be recognized over the next 4.2 years and the weighted average period of recognizing these costs is expected to be 1.2 years.

Equity Plans Activity

Stock Options

There were no stock options awarded during the three-month periods ended March 31, 2019 and 2018. A summary of option activity under the Plans as of March 31, 2018 and changes during the period then ended is presented below:

Options	Shares		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term		Aggregate Intrinsic Value ($000)

Non-vested at March 31, 2019		7,136	$	9.29		5.8 years	$	26

Restricted Stock

There were 18,394 shares of restricted stock awarded during the three-month period ended March 31, 2019 and 11,599 shares of restricted stock awarded during the three-month period ended March 31, 2018. There were 3,864 and 14,917 restricted stock awards that were fully vested during the three-month periods ended March 31, 2019 and 2018, respectively. The intrinsic value of nonvested restricted stock at March 31, 2019 was $612,000.

Restricted Stock	Shares		Weighted Average Grant Date Fair Value
Nonvested at January 1, 2019		32,528	$	14.60
Awarded		18,394		14.05
Less: Vested		3,864		15.30
Less: Expired, forfeited or cancelled		—		—
Nonvested at March 31, 2019		47,058	$	14.32

Other Equity Awards

There were no stock appreciation rights, restricted performance stock, unrestricted Company stock, or performance units awarded during the three-month periods ended March 31, 2019 or 2018 or outstanding at March 31, 2019 or December 31, 2018.

The intrinsic value used for stock options and restricted stock was derived from the market price of the Company’s common stock of $13.00 as of March 31, 2019.

3. COMMITMENTS AND CONTINGENCIES

In the normal course of business there are outstanding various commitments to extend credit which are not reflected in the financial statements, including loan commitments of approximately $32,047,000 and standby letters of credit of approximately $240,000 at March 31, 2019 and loan commitments of approximately $34,276,000 and standby letters of credit of approximately $361,000 at December 31, 2018. Such commitments relate primarily to real estate construction loans, revolving lines of credit and other commercial loans. However, all such commitments will not necessarily culminate in actual extensions of credit by the Company during 2019 as some of these are expected to expire without being fully drawn upon.

Standby letters of credit are commitments issued to guarantee the performance or financial obligation of a client to a third party. These guarantees are issued primarily relating to purchases of inventory, insurance programs, performance obligations to government agencies, or as security for real estate rents by commercial clients and are typically short-term in nature. Credit risk is similar to that involved in extending loan commitments to clients and accordingly, evaluation and collateral requirements similar to those for loan commitments are used. The majority of all such commitments are collateralized. The fair value of the liability related to these standby letters of credit, which represents the fees received for issuing the guarantees, was not significant at March 31, 2019 or December 31, 2018.

4. EARNINGS PER SHARE COMPUTATION

Basic earnings per share is computed by dividing net income by the weighted average common shares outstanding for the period (5,836,579 shares and 5,996,146 shares for the three-month periods ended March 31, 2019 and 2018, respectively). Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock, such as stock options or restricted stock, result in the issuance of common stock. Diluted earnings per share is computed by dividing net income by the weighted average common shares outstanding for the period plus the dilutive effect of stock based awards (21,048 shares for the three-month period ended March 31, 2019 and 36,641 shares for the three-month period ended March 31, 2018). For the three-month periods ended March 31, 2019 and 2018, there were zero stock options that were excluded from the calculation as they were considered antidilutive. Earnings per share is retroactively adjusted for stock dividends and stock splits, if applicable, for all periods presented.

5. INVESTMENT SECURITIES

The amortized cost and estimated fair values of investment securities at March 31, 2019 and December 31, 2018 consisted of the following (dollars in thousands):

There were no held-to-maturity investment securities with unrealized losses as of March 31, 2019 or December 31, 2018.

At March 31, 2019, the Company held 217 securities of which 8 were in a loss position for less than twelve months and 97 were in a loss position for twelve months or more. Of the 97 securities in a loss position for greater than twelve months at March 31, 2019, one was a municipal security, two were corporate securities, and 94 were US Government Agencies and Sponsored Agencies securities. At December 31, 2018, the Company held 220 securities of which 26 were in a loss position for less than twelve months and 97 were in a loss position for twelve months or more. Of the 97 securities in a loss position for greater than twelve months at December 31, 2018, one was a corporate securities, five were municipal securities and 91 were US Government Agencies and Sponsored Agencies securities.

The unrealized loss on the Company’s investment securities is primarily driven by interest rates. Because the decline in market value is attributable to a change in interest rates and not credit quality, and because the Company has the ability and intent to hold these investments until recovery of fair value, which may be until maturity, management does not consider these investments to be other-than-temporarily impaired.

The amortized cost and estimated fair values of investment securities at March 31, 2019 by contractual maturity are shown below (dollars in thousands).

	Available-for-Sale				Held-to-Maturity
	Amortized Cost		Estimated Fair Value		Amortized Cost		Estimated Fair Value

Within one year	$	2,243	$	2,244
After one year through five years		3,596		3,609

Expected maturities will differ from contractual maturities because the issuers of the securities may have the right to call or prepay obligations with or without call or prepayment penalties.

6. IMPAIRED AND NONPERFORMING LOANS AND LEASES AND OTHER REAL ESTATE OWNED

At March 31, 2019 and December 31, 2018, the recorded investment in nonperforming loans and leases was approximately $25,000 and $27,000, respectively. Nonperforming loans and leases include all such loans and leases that are either placed on nonaccrual status or are 90 days past due as to principal or interest but still accrue interest because such loans are well-secured and in the process of collection. 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 contractual terms of the original loan agreement. At March 31, 2019, the recorded investment in loans and leases that were considered to be impaired totaled $8,640,000. Of the total impaired loans of $8,640,000, loans totaling $5,936,000 were deemed to require no specific reserve and loans totaling $2,704,000 were deemed to require a related valuation allowance of $164,000. At December 31, 2018, the recorded investment in loans and leases that were considered to be impaired totaled $8,702,000 and had a related valuation allowance of $185,000.

At March 31, 2019 and December 31, 2018, the recorded investment in other real estate owned (“OREO”) was $957,000. During the first quarter of 2019, the Company did not add any new or sell or impair any of the OREO properties. The March 31, 2019 and December 31, 2018 OREO balance of $957,000 consisted of one commercial land property.

Nonperforming loans and leases and other assets and OREO at March 31, 2019 and December 31, 2018 are summarized as follows (in thousands):

	March 31, 2019			December 31, 2018

9. LEASES

The Company adopted ASU 2016-02, Leases (Topic 842), on January 1, 2019, using the alternative transition method whereby comparative periods were not restated. No cumulative effect adjustment to the opening balance of retained earnings was required. The Company also elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things allowed the Company to carry forward the historical lease classifications. Additionally, the Company elected the hindsight practical expedient to determine the lease term for existing leases.

The Company leases nine locations for administrative offices and branch locations. All leases were classified as operating leases. Leases with an initial term of 12 months or less are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the lease term. The Company elected to use the practical expedient to not recognize short-term leases on the consolidated balance sheet and instead account for them as executory contracts.

Certain leases include options to renew, with renewal terms that can extend the lease term, typically for five years. Lease assets and liabilities include related options that are reasonably certain of being exercised, however, in the case of those leases that have renewal options, the Company is not including those additional lease terms as the rates are undeterminable and it has been the Company’s historical practice to renegotiate lease terms upon expiration of the original lease terms. The depreciable life of leased assets are limited by the expected lease term.

Adoption of this standard resulted in the Company recognizing a right of use asset and a corresponding lease liability of $3,570,000 on January 1, 2019.

Supplemental lease information at or for the three months ended March 31, 2019 is as follows:

Balance Sheet

Operating lease asset classified as premises and equipment	$	3,372,000
Operating lease liability classified as other liabilities		3,372,000

Income Statement

Operating lease cost classified as occupancy and equipment expense	$	188,000
Weighted average lease term, in years		6.33
Weighted average discount rate (1)		3.03	%
Operating cash flows	$	189,000

(1)

The discount rate was developed by using the fixed rate credit advance borrowing rate at the Federal Home Loan Bank of San Francisco for a term correlating to the remaining life of each lease.

A maturity analysis of the Company’s lease liabilities at March 31, 2019 was as follows:

	Balance
April 1, 2019 to March 31, 2020	$	728,000
April 1, 2020 to March 31, 2021		689,000
April 1, 2021 to March 31, 2022		653,000
April 1, 2022 to March 31, 2023		539,000
April 1, 2023 to March 31, 2024		283,000
Thereafter		859,000
Total lease payments		3,751,000
Less: Interest		(379,000	)
Present value of lease liabilities	$	3,372,000

10. BORROWING ARRANGEMENTS

At March 31, 2019, the Company had $17,000,000 of unsecured short-term borrowing arrangements with two of its correspondent banks. There were no advances under the borrowing arrangements as of March 31, 2019 or December 31, 2018.

The Company has a line of credit available with the Federal Home Loan Bank of San Francisco (the “FHLB”) which is secured by pledged mortgage loans and investment securities. Borrowings may include overnight advances as well as loans with terms of up to thirty years. Advances (both short-term and long-term) totaling $29,500,000 were outstanding from the FHLB at March 31, 2019, bearing interest rates ranging from 1.18% to 3.17% and maturing between April 1, 2021 and November 24, 2023. Advances totaling $15,500,000 were outstanding from the FHLB at December 31, 2018, bearing interest rates ranging from 1.18% to 3.17% and maturing between April 30, 2019 and November 24, 2023. Remaining amounts available under the borrowing arrangement with the FHLB at March 31, 2019 and December 31, 2018 totaled $92,451,000 and $107,262,000, respectively. In addition, the Company has a secured borrowing agreement with the Federal Reserve Bank of San Francisco. The borrowing can be secured by pledging selected loans and investment securities. Borrowings generally are short-term including overnight advances as well as loans with terms up to ninety days. Amounts available under this borrowing arrangement at March 31, 2019 and December 31, 2018 were $6,465,000 and $8,340,000, respectively. There were no advances outstanding under this borrowing arrangement as of March 31, 2019 and December 31, 2018.

11. INCOME TAXES

The Company files its income taxes on a consolidated basis with its subsidiaries. The allocation of income tax expense (benefit) represents each entity’s proportionate share of the consolidated provision for (benefit from) income taxes.

The Company accounts for income taxes using the balance sheet method, under which deferred tax assets and liabilities are recognized for the tax consequences of temporary differences between the reported amounts of assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. On the consolidated balance sheet, net deferred tax assets are included in accrued interest receivable and other assets.

The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above, if applicable, is reflected as a liability for unrecognized tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company recognizes accrued interest and penalties related to unrecognized tax benefits, if applicable, as a component of interest expense in the consolidated statement of income. There have been no unrecognized tax benefits or accrued interest and penalties for the three-month periods ended March 31, 2019 and 2018.

12. FAIR VALUE MEASUREMENTS

The following tables present information about the Company’s assets and liabilities measured at fair value on a recurring and nonrecurring basis as of March 31, 2019 and December 31, 2018. They indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In 2018, the Company adopted the provisions of Accounting Standard Update 2016-01 “ Recognition and Measurement of Financial Assets and Financial Liabilities ” (“ASU 2016-01”). ASU 2016-01 requires the Company to use the exit price notion when measuring the fair value of financial instruments. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Estimated fair values are disclosed for financial instruments for which it is practicable to estimate fair value. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. The carrying amounts and estimated fair values of the Company’s financial instruments are as follows (dollars in thousands):

Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the fair values presented.

Assets and liabilities measured at fair value on a recurring and non-recurring basis are presented in the following table:

There were no transfers between Levels 1 and 2 during the three-month period ended March 31, 2019 or the twelve months ended December 31, 2018.

The following methods were used to estimate the fair value of each class of financial instrument above:

Available-for-sale securities – Fair values for investment securities are based on quoted market prices, if available, and are considered Level 1, or evaluated using pricing models that vary by asset class and incorporate available trade, bid and other market information and are considered Level 2. Pricing applications apply available information, as applicable, through processes such as benchmark curves, benchmarking to like securities, sector groupings and matrix pricing.

Impaired loans – The fair value of collateral dependent impaired loans adjusted for specific allocations of the allowance for loan losses is generally based on recent real estate appraisals and/or evaluations. These appraisals and/or evaluations may utilize a single valuation approach or a combination of approaches including comparable sales, cost and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income and other available data. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. The valuation technique used for all Level 3 nonrecurring impaired loans is the sales comparison approach less a reserve for past dues taxes and selling costs ranging from 8% to 10%.

Other real estate owned – Certain commercial and residential real estate properties classified as OREO are measured at fair value, less costs to sell. Fair values are based on recent real estate appraisals and/or evaluations. These appraisals and/or evaluations may use a single valuation approach or a combination of approaches including comparable sales, cost and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income and other available data. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. The valuation technique used for all Level 3 nonrecurring OREO is the sales comparison approach less selling costs ranging from 8% to 10%.

13. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In February 2016, the FASB issued ASU No. 2016-02, “ Leases. ” Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases): 1) a lease liability, which is the present value of a lessee’s obligation to make lease payments, and 2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessor accounting under the new guidance remains largely unchanged as it is substantially equivalent to existing guidance for sales-type leases, direct financing leases, and operating leases. Leveraged leases have been eliminated, although lessors can continue to account for existing leveraged leases using the current accounting guidance. Other limited changes were made to align lessor accounting with the lessee accounting model and the new revenue recognition standard . All entities will classify leases to determine how to recognize lease-related revenue and expense. Quantitative and qualitative disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The intention is to require enough information to supplement the amounts recorded in the financial statements so that users can understand more about the nature of an entity’s leasing activities. ASU No. 2016-02 was effective for interim and annual reporting periods beginning after December 15, 2018; early adoption was permitted. All entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. They have the option to use certain relief; full retrospective application is prohibited. Based on evaluation of the Company’s current lease obligations, the Company has determined that the provisions of ASU No. 2016-02 resulted in an increase in assets to recognize the present value of the lease obligations with a corresponding increase in liabilities. The Company currently leases nine of its office leases under operating leases. The Company adopted ASU No. 2016-02 on January 1, 2019. The Company’s present value of future lease payments as of January 1, 2019 is $3,570,000, to be recorded as a right-of-use asset with an offsetting liability. The effects of adopting ASU No. 2016-02 did not have a material impact on the Company’s financial position, results of operations or cash flows.

In June 2016, the FASB issued ASU No. 2016-13, “ Measurement of Credit Losses on Financial Instruments. ” This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren’t measured at fair value through net income. In issuing the standard, the FASB is responding to criticism that today’s guidance delays recognition of credit losses. The standard will replace today’s “incurred loss” approach with an “expected loss” model. The new model, referred to as the current expected credit loss (“CECL”) model, will apply to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance sheet credit exposures. This includes, but is not limited to, loans, leases, held-to-maturity securities, loan commitments, and financial guarantees. The CECL model does not apply to available-for-sale (“AFS”) debt securities. For AFS debt securities with unrealized losses, entities will measure credit losses in a manner similar to what they do today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. As a result, entities will recognize improvements to estimated credit losses immediately in earnings rather than as interest income over time, as they do today. The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU No. 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective approach). While the Company is currently evaluating the provisions of ASU No. 2016-13 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements, it has taken steps to prepare for the implementation when it becomes effective, such as forming an internal task force, gathering pertinent data, consulting with outside professionals, evaluating its current IT systems, and purchasing a software solution. The Company has imported current and historical data into the new software and is currently validating the data and intends to begin processing information, on a test basis, with the new CECL specific software during 2019 and to disclose any material potential impact of this modeling once it becomes available.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following is management’s discussion and analysis of the significant changes in American River Bankshares’ (the “Company”) balance sheet accounts between December 31, 2018 and March 31, 2019 and its income and expense accounts for the three-month periods ended March 31, 2019 and 2018. The discussion is designed to provide a better understanding of significant trends related to the Company’s financial condition, results of operations, liquidity, capital resources and interest rate sensitivity. This discussion and supporting tables and the consolidated financial statements and related notes appearing elsewhere in this report are unaudited. Interest income and net interest income are presented on a fully taxable equivalent basis (FTE) within management’s discussion and analysis.

the reputation of the financial services industry could experience deterioration, which could adversely affect our ability to access markets for funding and to acquire and retain customers; and

the efficiencies we may expect to receive from any investments in personnel and infrastructure may not be realized.

The factors set forth under “Item 1A - Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, and other cautionary statements and information set forth in this Quarterly Report on Form 10-Q should be carefully considered and understood as being applicable to all related forward-looking statements contained in this Quarterly Report on Form 10-Q, when evaluating the business prospects of the Company and its subsidiaries.

Forward-looking statements are not guarantees of performance. By their nature, they involve risks, uncertainties and assumptions. The future results and shareholder values may differ significantly from those expressed in these forward-looking statements. You are cautioned not to put undue reliance on any forward-looking statement. Any such statement speaks only as of the date of this report, and in the case of any documents that may be incorporated by reference, as of the date of those documents. We do not undertake any obligation to update or release any revisions to any forward-looking statements, to report any new information, future event or other circumstances after the date of this report or to reflect the occurrence of unanticipated events, except as required by law. However, your attention is directed to any further disclosures made on related subjects in our subsequent reports filed with the Securities and Exchange Commission (the “SEC”) on Forms 10-K, 10-Q and 8-K.

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.

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 and lease 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 and Lease Losses

The allowance for loan and lease 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.

The allowance for loan and lease 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. If the allowance for loan and lease losses falls below that deemed adequate (by reason of loan and lease growth, actual losses, the effect of changes in risk factors, or some combination of these), the Company has a strategy for supplementing the allowance for loan and lease losses, over the short-term. For further information regarding our allowance for loan and lease losses, see “Allowance for Loan and Lease Losses Activity.”

Stock-Based Compensation

The Company recognizes compensation expense over the service period in an amount equal to the fair value of all share-based payments which consist of stock options and restricted stock awarded to directors and employees. The fair value of each stock option award is estimated on the date of grant and amortized over the service period using a Black-Scholes-Merton based option valuation model that requires the use of assumptions. Critical assumptions that affect the estimated fair value of each award include expected stock price volatility, dividend yields, option life and the risk-free interest rate. The fair value of each restricted award is estimated on the date of award and amortized over the service period.

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 103 full-time employees as of March 31, 2019.

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.

In 2000, the Company acquired North Coast Bank as a separate bank subsidiary. North Coast Bank was incorporated and commenced business in 1990 as Windsor Oaks National Bank in Windsor, California. In 1997, the name was changed to North Coast Bank. Effective December 31, 2003, North Coast Bank was merged with and into American River Bank. On December 3, 2004, the Company acquired Bank of Amador located in Jackson, California. Bank of Amador was merged with and into American River Bank.

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 also conducts lease financing for certain types of business equipment. 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 2019 and 2018, 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.”

Results of Operations

Net Interest Income and Net Interest Margin

Net interest income represents the excess of interest and fees earned on interest earning assets (loans and leases, 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 3.59% for the three months ended March 31, 2019 and 3.29% for the three months ended March 31, 2018.

The fully taxable equivalent interest income component for the first quarter of 2019 increased $1,055,000 (20.6%) to $6,180,000 compared to $5,125,000 for the three months ended March 31, 2018. The decrease in the fully taxable equivalent interest income for the first quarter of 2019 compared to the same period in 2018 is broken down by rate (up $711,000) and volume (up $344,000). The primary driver in this rate increase was an increase in the yield on loans which saw an increase from 4.59% in the first quarter of 2018 to 4.93% in the first quarter of 2019 and an increase in the yield on investments, which saw an increase from 2.36% in the first quarter of 2018 to 2.87% in the first quarter of 2019. The increased yield in 2019 compared to 2018 was due to the overall higher interest rate environment. The yield on earning assets increased from 3.51% during the first quarter of 2018 to 3.96% during the first quarter of 2019. The volume increase of $344,000 was primarily from an increase in loans ($241,000) and an increase in investment balances ($134,000). Average loans balances increased $21,304,000, (or 6.9%), from $307,266,000 during the first quarter of 2018 to $328,570,000 during the first quarter of 2019 and the average investment balances increased $28,157,000, (or 10.5%), from $269,109,000 during the first quarter of 2018 to $297,266,000 during the first quarter of 2019.

Interest expense was $583,000 or $254,000 (77.2%) higher in the first quarter of 2019 versus $329,000 in the first quarter of 2018. The net $254,000 increase in interest expense during the first quarter of 2019 compared to the first quarter of 2018 was predominantly due to higher rates (up $221,000). Increased volume added an additional expense of $33,000. The increase in deposit expense can be attributed to the higher rate environment particularly from an increase in rates paid on time deposit balances. Some of these time deposits are indexed to the three-month or six-month treasury rates which have increased over the past twelve months. Interest expense on time deposits related to rate was $155,000. Rates paid on interest bearing liabilities increased 25 basis points from 0.35% to 0.60% for the first quarter of 2018 compared to the same period in 2019.

Provision for Loan and Lease Losses

The Company added $180,000 to the provision for loan and lease losses for the first quarter of 2019 compared to zero in the first quarter of 2018. The Company experienced net loan and lease recoveries of $5,000 or (0.01%) (on an annualized basis) of average loans and leases for the three months ended March 31, 2019 compared to net loan and lease recoveries of $10,000 or (0.01%) (on an annualized basis) of average loans and leases for the three months ended March 31, 2018. The Company continued to experience an overall improvement in the credit quality of the loan and lease portfolio and a reduction of credit losses, however, due to the net growth in the loans outstanding during the first quarter of 2019, management believed the $180,000 addition to the provision for loan and lease losses was warranted. For additional information see the “Allowance for Loan and Lease Losses Activity.”

Noninterest Income

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

Table Four: Components of Noninterest Income

	Three Months Ended March 31,
	2019		2018
Service charges on deposit accounts	$	121	$	117
Gain on sale of securities		36		1
Merchant fee income		90		110
Bank owned life insurance		81		75
Other		83		69
Total noninterest income	$	411	$	372

Noninterest income increased $39,000 (10.5%) to 411,000 for the three months ended March 31, 2019 as compared to $372,000 for the three months ended March 31, 2018. The increase in noninterest income was primarily related to higher gains from sales of securities, which increased from $1,000 in 2018 to $36,000 in 2019.

Noninterest Expense

Noninterest expense increased $910,000 (27.2%) to a total of $4,260,000 in the first quarter of 2019 compared to $3,350,000 in the first quarter of 2018. Salary and employee benefits expense increased $575,000 (26.1%) from $2,206,000 during the first quarter of 2018 to $2,781,000 during the first quarter of 2019. The increase in salaries and benefits expense resulted from filling some vacant positions, hiring additional relationship managers, replacing the Chief Credit Officer, and normal cost of living increases and promotions. Average full-time equivalent employees was 103 during the first quarter of 2019 compared to 90 during the first quarter of 2018. On a quarter-over-quarter basis, occupancy expense decreased $5,000 (1.9%) and furniture and equipment expense increased $2,000 (1.4%). FDIC assessments decreased $3,000 (5.7%) from the first quarter of 2018 to the first quarter of 2019. OREO related expenses decreased $1,000 (20.0%) during the first quarter of 2019 from $5,000 in the first quarter of 2018 to $4,000 in the first quarter of 2019. Other expense increased $342,000 (49.9%) to $1,028,000 in the first quarter of 2019 compared to $686,000 in the first quarter of 2018. There were numerous line items that make up the $342,000 increase in other expenses including advertising and business development (increased $115,000), correspondent bank charges (increased $117,000), professional fees (increased $23,000), and director expenses (increased $28,000). Much of this increase in advertising and business development is related to the expenses to sponsor community events and other promotional activities as the Company is focusing more effort in our markets to strengthen our brand. The increase in correspondent bank charges relates to lower average balances maintained by the Company in these accounts resulting in higher service charges and the interest earned on these balances has increased due to the higher interest rate environment and beginning in 2019 is being considered as interest income by the Company and classified as such and is reflected in the higher balances in the interest due from banks in the consolidated statement of income. The fully taxable equivalent efficiency ratio increased from 64.8% for the first quarter of 2018 to 70.9% for the first quarter of 2019.

Provision for Income Taxes

Federal and state income taxes for the quarter ended March 31, 2019 decreased $32,000 (7.9%) from $406,000 in the first quarter of 2018 to $374,000 in the first quarter of 2019. The effective tax rate for the quarter ended March 31, 2019 was 24.6% compared to 23.1% for the first quarter of 2018. The lower tax expense was related to the lower level of taxable income in 2019 ($1,520,000) compared to 2018 ($1,759,000). The higher effective tax rate in 2019 compared to 2018 is related to the tax treatment of equity based compensation under Accounting Standards Update 2016-09 (“ASU 2016-09”). Under ASU 2016-09, if the market value of the Company’s stock price on the date restricted stock vests is higher than the Company’s stock price on the date the restricted stock was awarded the Company receives a tax credit for the difference in values and if the market price on the vesting date is lower than the stock price on the award date the Company recognizes additional tax expense. In the first quarter of 2018 the Company recognized an $87,000 tax credit under ASU 2016-09 and in the first quarter of 2019 the Company recognized a $5,000 tax expense under ASU 2016-09.

Balance Sheet Analysis

The Company’s total assets were $689,368,000 at March 31, 2019 as compared to $688,092,000 at December 31, 2018, representing an increase of $1,276,000 (0.2%). The average assets for the three months ended March 31, 2019 were $686,162,000, which represents an increase of $2,770,000 or 0.4% over the balance of $683,392,000 during the three-month period ended March 31, 2018.

Federal Funds

The balance held in correspondent banks classified as Federal funds at March 31, 2019, was zero compared to $7,000,000 at December 31, 2018. The primary reason for the decrease in Federal funds since December 31, 2018 is directly related to the increase in loan balances during the same period.

Investment Securities

Table Five below summarizes the values of the Company’s investment securities held on March 31, 2019 and December 31, 2018.

Table Five: Investment Securities Composition

(dollars in thousands)
Available-for-sale (at fair value)	March 31, 2019		December 31, 2018
Debt securities:
US Government Agencies and Sponsored Agencies	$	265,427	$	269,049
Obligations of states and political subdivisions		12,639		14,400
Corporate bonds		6,547		6,508
US Treasury securities		1,989		4,976
Total available-for-sale investment securities	$	286,602	$	294,933
Held-to-maturity (at amortized cost)
Debt securities:
US Government Agencies and Sponsored Agencies	$	277	$	292
Total held-to-maturity investment securities	$	277	$	292

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 losses on available-for-sale investment securities totaling $74,000 were recorded, net of $22,000 in tax assets, as accumulated other comprehensive loss within shareholders’ equity at March 31, 2019 and net unrealized losses on available-for-sale investment securities totaling $2,664,000 were recorded, net of $788,000 in tax liabilities, as accumulated other comprehensive loss within shareholders’ equity at December 31, 2018.

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 and Leases

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) lease financing receivable; (7) agriculture; and (8) 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 $30.5 million in new loans during the first three months of 2019. This production was partially offset by pay downs and payoffs, but resulted in an overall increase in net loans and leases of $17,491,000 (5.5%) from December 31, 2018.

A significant portion of the Company’s loans and leases are direct loans and leases 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 and leases 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 3 to 10 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 and lease portfolio. Management believes its ability to identify and assess risk and return characteristics of the Company’s loan and lease portfolio is critical for profitability and growth. Management strives to continue its emphasis on credit quality in the loan and lease approval process, through active credit administration and regular monitoring. With this in mind, management has designed and implemented a comprehensive loan and lease review and grading system that functions to continually assess the credit risk inherent in the loan and lease portfolio.

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 serviced markets in Santa Clara, Contra Costa, and Alameda Counties through a loan production office. In the fourth quarter of 2016, the Company discontinued operating the loan production office, however, the Company continues to service loans originated through these offices. The economies of Santa Clara, Contra Costa and Alameda Counties are diversified with professional services, manufacturing, technology related companies, real estate investment and construction.

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 and lease portfolio at March 31, 2019 and 87% as of December 31, 2018. 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, 2019, outstanding unimproved residential land and construction loans were $6,773,000 (or just 2.4% of the total real estate loans). Of the $6,773,000, $2,079,000 (31%) was represented by one amortizing loan, which was considered well-secured, with a favorable loan-to-value ratio. Management currently believes that it maintains its allowance for loan and lease 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 and lease losses. This could adversely affect the Company’s future prospects, results of operations, profitability and stock price. 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: (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 and Leases

Management places loans and leases on nonaccrual status when they become 90 days past due or if a loss is expected, unless the loan or lease is well secured and in the process of collection. Loans and leases are partially or fully charged off when, in the opinion of management, collection of such amount appears unlikely. The recorded investments in nonperforming loans and leases, which includes nonaccrual loans and leases and loans and leases that were 90 days or more past due and on accrual, totaled $25,000 and $27,000 at March 31, 2019 and December 31, 2018, respectively. The $25,000 in nonperforming loans and leases at March 31, 2019 were comprised of one commercial loan relationship with two loans totaling $27,000, both of which were current to terms.

There were no loan or lease concentrations in excess of 10% of total loans and leases not otherwise disclosed as a category of loans and leases as of March 31, 2019. Management is not aware of any potential problem loans, which were accruing and current at March 31, 2019, 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, 2019 and December 31, 2018.

Impaired Loans and Leases

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 or lease agreement. The measurement of impairment may be based on (i) the present value of the expected cash flows of the impaired loan or lease discounted at the loan’s or lease’s original effective interest rate, (ii) the observable market price of the impaired loan or lease, or (iii) the fair value of the collateral of a collateral-dependent loan. The Company does not apply this definition to smaller-balance loans or leases that are collectively evaluated for credit risk. In assessing whether a loan or lease is impaired, the Company typically reviews loans or leases 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, 2019, the recorded investment in loans and leases that were considered to be impaired totaled $8,640,000, all of which are considered performing loans and leases. Of the total impaired loans of $8,640,000, loans totaling $5,936,000 were deemed to require no specific reserve and loans totaling $2,704,000 were deemed to require a related valuation allowance of $164,000. Of the $5,936,000 impaired loans that did not carry a specific reserve there were $489,000 in loans or leases that had previous partial charge-offs and $5,447,000 in loans or leases 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 or lease balance. The recorded investment in loans and leases that were considered to be impaired totaled $8,702,000 at December 31, 2018. Of the total impaired loans of $8,702,000, loans totaling $5,968,000 were deemed to require no specific reserve and loans totaling $2,734,000 were deemed to require a related valuation allowance of $185,000.

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 2019, the Company had net loan recoveries of $5,000 with $180,000 in provisions for loan and lease losses. Despite the Company’s continued improvement in the credit quality of the loan and lease portfolio, due to the net growth in the loans outstanding during the first quarter of 2019, the $180,000 addition to the provision for loan and lease losses was warranted. In the first quarter of 2018, the Company had net loan recoveries of $10,000 with no added provision.

During the periods ended March 31, 2019 and March 31, 2018, there were no loans that were modified as troubled debt restructurings. There were no payment defaults during the three months ended March 31, 2019 or March 31, 2018 on troubled debt restructurings made in the preceding twelve months. At March 31, 2019 and December 31, 2018, there were no unfunded commitments on those loans considered troubled debt restructures.

Allowance for Loan and Lease Losses Activity

The Company maintains an allowance for loan and lease losses (“ALLL”) to cover probable losses inherent in the loan and lease portfolio, which is based upon management’s estimate of those losses. The ALLL is established through a provision for loan and lease losses and is increased by provisions charged against current earnings and recoveries and reduced by charge-offs. Actual losses for loans and leases 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 and lease 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 and leases 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 or leases and exposure to potential losses.

The ALLL totaled $4,577,000 or 1.34% of total loans and leases at March 31, 2019 compared to $4,392,000 or 1.36% of total loans and leases at December 31, 2018. The Company establishes general and specific reserves in accordance with accounting principles generally accepted in the United States of America. 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 and lease portfolio based on loan type and loan rating; however, the entire allowance is available to cover actual loan and lease losses. While management uses available information to recognize possible losses on loans and leases, 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 ALLL as a percentage of non-performing loans and leases was 183.1 times the nonperforming loans and leases at March 31, 2019 and 162.7 times the nonperforming loans and leases at December 31, 2018. The allowance for loans and leases as a percentage of impaired loans and leases was 53.0% at March 31, 2019 and 50.5% at December 31, 2018. Of the total non-performing and impaired loans and leases outstanding as of March 31, 2019, there were $814,000 in loans or leases that had been reduced by partial charge-offs of $297,000.

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

It is the policy of management to maintain the allowance for loan and lease 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 and lease 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 and lease losses is prudent and adequate. However, no prediction of the ultimate level of loans and leases charged off in future periods can be made with any certainty.

Other Real Estate Owned

At March 31, 2019 and December 31, 2018, the Company had one other real estate owned (“OREO”) property totaling $957,000. During the first quarter of 2019, 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, 2019 nor at year-end 2018. The Company believes that the OREO property owned at March 31, 2019 was carried approximately at fair value.

Deposits

At March 31, 2019, total deposits were $572,379,000 representing an $18,295,000 (3.1%) decrease from the December 31, 2018 balance of $590,674,000. The Company’s deposit growth plan for 2019 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. The Company’s balances in noninterest-bearing checking, interest-bearing checking, savings and time, in total, remained relatively unchanged from December 31, 2018 decreasing in overall by $5,430,000 (1.2%), however, money market accounts decreased $12,865,000 (8.8%) due in part to one relationship transferring a portion of their deposit relationship in the amount of $10,000,000 to another financial institution for investment purposes.

Other Borrowed Funds

Other borrowings outstanding as of March 31, 2019 and December 31, 2018, 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 2019 and 2018 was $19,000,000 and $3,500,000, 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 in thousands) as of March 31, 2019:

Capital Resources

The Company and American River Bank are subject to certain regulatory capital requirements administered by the Federal Reserve Board 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 current 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, 2019, shareholders’ equity was $77,576,000, representing an increase of $2,855,000 (3.8%) from $74,721,000 at December 31, 2018. The increase results from net income for the period ($1,146,000), stock based compensation ($178,000), and the increase from other comprehensive income ($1,824,000), exceeding the payment of cash dividends ($293,000). Table Ten below lists the Company’s and American River Bank’s capital ratios at March 31, 2019 and December 31, 2018, as well as the minimum capital ratios for capital adequacy and the minimum requirement for a well-capitalized institution.

On January 24, 2018, the Company approved and authorized a 5% stock repurchase program for 2018 (the “2018 Program”). See Part II, Item 2, for additional disclosure regarding the 2018 Program. In addition, on February 13, 2019, the Company paid a $0.05 per common share cash dividend to shareholders of record on January 30, 2019. This 2019 quarterly dividend follows four quarterly cash dividends, totaling $0.20 per share, paid in 2018. Capital ratios are reviewed on a regular basis to ensure that capital exceeds the prescribed regulatory requirements and is adequate to meet future needs. Management believes that both the Company and American River Bank met all of their capital adequacy requirements as of March 31, 2019 and December 31, 2018.

Effective January 1, 2015, bank holding companies with consolidated assets of $1 Billion or more ($3 Billion or more effective August 30, 2018) and banks like American River Bank must comply with new minimum capital ratio requirements to be phased-in between January 1, 2015 and January 1, 2019, which consist of the following: (i) a new 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%.

In addition, a “capital conservation buffer,” was established which was is now fully phased-in and 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 new buffer requirement was phased-in between January 1, 2016 and January 1, 2019. The buffer requirement for 2018 was 1.875% and became fully phased in on January 1, 2019, increasing to 2.50%. 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, 2019 and 2018.

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 and lease repayments contribute to liquidity, along with deposit increases, while loan and lease 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, 2019 were approximately $32,047,000 and $240,000, 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, 2019, consolidated liquid assets totaled $206.4 million or 29.9% of total assets compared to $226.5 million or 32.9% of total assets on December 31, 2018. 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, 2019, the Company had $17,000,000 available under these credit lines. Additionally, the Bank is a member of the FHLB. At March 31, 2019, the Bank could have arranged for up to $121,951,000 in secured borrowings from the FHLB. These borrowings are secured by pledged mortgage loans and investment securities. At March 31, 2019, the Company had advances, borrowings and commitments (including letters of credit) outstanding of $29,500,000, leaving $92,451,000 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, 2019, the Company’s borrowing capacity at the Federal Reserve Bank was $6,465,000. 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.

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, 2019 and December 31, 2018, 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 $32,287,000 and $35,113,000 at March 31, 2019 and December 31, 2018, respectively. As a percentage of net loans and leases these off-balance sheet items represent 9.6% and 11.0%, respectively. See also, Note 3 to the unaudited consolidated financial statements included herein for additional information about the Company’s off-balance sheet items.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Overview . Market risk is the risk of loss from adverse changes in market prices and rates. The Company’s market risk arises primarily from interest rate risk inherent in its loan, investment and deposit functions. The goal for managing the assets and liabilities of the Company is to maximize shareholder value and earnings while maintaining a high quality balance sheet without exposing the Company to undue interest rate risk. The Board of Directors has overall responsibility for the interest rate risk management policies. The Company has an Enterprise Risk Management Committee, made up of Company management that establishes and monitors guidelines to control the sensitivity of earnings to changes in interest rates.

Asset/Liability Management . Activities involved in asset/liability management include but are not limited to lending, accepting and placing deposits and investing in securities. Interest rate risk is the primary market risk associated with asset/liability management. Sensitivity of earnings to interest rate changes arises when yields on assets change in a different time period or in a different amount from that of interest costs on liabilities. To mitigate interest rate risk, the structure of the balance sheet is managed with the goal that movements of interest rates on assets and liabilities are correlated and contribute to earnings even in periods of volatile interest rates. The asset/liability management policy sets limits on the acceptable amount of variance in net interest margin and market value of equity under changing interest environments. The Company uses simulation models to forecast earnings, net interest margin and market value of equity.

Simulation of earnings is the primary tool used to measure the sensitivity of earnings to interest rate changes. Using computer-modeling techniques, with specialized software built for this specific purpose for financial institutions, the Company is able to estimate the potential impact of changing interest rates on earnings, net interest margin and market value of equity. A balance sheet is prepared using detailed inputs of actual loans, securities and interest-bearing liabilities (i.e. deposits/borrowings). The balance sheet is processed using multiple interest rate scenarios. The scenarios include a rising rate forecast, a flat rate forecast and a falling rate forecast which take place within a one-year time frame. The net interest income is measured over one-year and two-year periods assuming a gradual change in rates over the twelve-month horizon. The simulation modeling attempts to estimate changes in the Company’s net interest income utilizing a detailed current balance sheet. Table Eleven below summarizes the effect on net interest income (NII) of a ±100 and ±200 basis point change in interest rates as measured against a constant rate (no change) scenario.

Table Eleven: Interest Rate Risk Simulation of Net Interest as of March 31, 2019

(dollars in thousands)	$ Change in NII from Current 12 Month Horizon			$ Change in NII from Current 24 Month Horizon
Variation from a constant rate scenario
+100bp	$	137		$	523
+200bp	$	194		$	844
-100bp	$	(507	)	$	(1,392	)
-200bp	$	(961	)	$	(2,979	)

After a review of the model results as of March 31, 2019, the Company does not consider the fluctuations from the base case, to have a material impact on the Company’s projected results and are within the tolerance levels outlined in the Company’s interest rate risk polices. The simulations of earnings do not incorporate any management actions, which might moderate the negative consequences of interest rate deviations. Therefore, they do not reflect likely actual results, but serve as reasonable estimates of interest rate risk.

Interest Rate Sensitivity Analysis Interest rate sensitivity is a function of the repricing characteristics of the portfolio of assets and liabilities. These repricing characteristics are the time frames within which the interest-bearing assets and liabilities are subject to change in interest rates either at replacement, repricing or maturity. Interest rate sensitivity management focuses on the maturity of assets and liabilities and their repricing during periods of changes in market interest rates. Interest rate sensitivity is measured as the difference between the volumes of assets and liabilities in the current portfolio that are subject to repricing at various time horizons. The differences are known as interest sensitivity gaps. A positive cumulative gap may be equated to an asset sensitive position. An asset sensitive position in a rising interest rate environment will cause a bank’s interest rate margin to expand. This results as floating or variable rate loans reprice more rapidly than fixed rate certificates of deposit that reprice as they mature over time. Conversely, a declining interest rate environment will cause the opposite effect. A negative cumulative gap may be equated to a liability sensitive position. A liability sensitive position in a rising interest rate environment will cause a bank’s interest rate margin to contract, while a declining interest rate environment will have the opposite effect.

Item 4. Controls and Procedures.

The Company, under the supervision and with the participation of its management, including the Chief Executive Officer and the Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s “disclosure controls and procedures” (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of March 31, 2019. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report.

During the quarter ended March 31, 2019, there have been no changes in the Company’s internal control over financial reporting that have significantly affected, or are reasonably likely to materially affect, these controls.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, the Company and/or its subsidiaries is a party to claims and legal proceedings arising in the ordinary course of business. The Company’s management is not aware of any significant pending legal proceedings to which either it or its subsidiaries may be a party or has recently been a party, which will have a significant adverse effect on the financial condition or results of operations of the Company or its subsidiaries, taken as a whole.

Item 1A. Risk Factors.

There have been no significant changes in the risk factors previously disclosed in the Company’s Form 10-K for the period ended December 31, 2018, filed with the Securities and Exchange Commission on February 21, 2019.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On January 24, 2018, the Company approved and authorized a stock repurchase program for 2018 (the “2018 Program”). The 2018 Program authorized the repurchase during 2018 of up to 5% of the outstanding shares of the Company’s common stock, or approximately 306,618 shares based on the 6,132,362 shares outstanding as of December 31, 2017. During 2018, the Company repurchased 306,618 shares of its common stock at an average price of $15.52 per share. Repurchases under the 2018 Program were made from time to time by the Company in the open market. All such transactions were structured to comply with Securities and Exchange Commission Rule 10b-18 and all shares repurchased under the 2018 Program were retired.

The Company did not repurchase any shares during the first quarter of 2019 and does not currently have a stock repurchase program in place.
