Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Business of Sierra Bancorp	Note 1 – The Business of Sierra Bancorp Sierra Bancorp (the “Company”) is a California corporation headquartered in Porterville, California, and is a registered bank holding company under federal banking laws. The Company was formed to serve as the holding company for Bank of the Sierra (the “Bank”), and has been the Bank’s sole shareholder since August 2001. The Company exists primarily for the purpose of holding the stock of the Bank and of such other subsidiaries it may acquire or establish. As of September 30, 2019, the Company’s only other subsidiaries were Sierra Statutory Trust II, Sierra Capital Trust III, and Coast Bancorp Statutory Trust II, which were formed solely to facilitate the issuance of capital trust pass-through securities (“TRUPS”). Pursuant to the Financial Accounting Standards Board (“FASB”) standard on the consolidation of variable interest entities, these trusts are not reflected on a consolidated basis in the Company’s financial statements. References herein to the “Company” include Sierra Bancorp and its consolidated subsidiary, the Bank, unless the context indicates otherwise. Bank of the Sierra, a California state-chartered bank headquartered in Porterville, California, offers a wide range of retail and commercial banking services via branch offices located throughout California’s South San Joaquin Valley, the Central Coast, Ventura County, and neighboring communities. The Bank was incorporated in September 1977, and opened for business in January 1978 as a one-branch bank with $1.5 million in capital. Our growth in the ensuing years has largely been organic in nature, but includes four whole-bank acquisitions: Sierra National Bank in 2000, Santa Clara Valley Bank in 2014, Coast National Bank in 2016, and Ojai Community Bank in October 2017. As of the filing date of this report the Bank operates 40 full service branches and an online branch, and maintains ATMs at all but one of our branch locations as well as seven non-branch locations. Moreover, the Bank has specialized lending units which focus on agricultural borrowers, SBA loans, and mortgage warehouse lending. The Company had total assets of $2.6 billion at September 30, 2019, and for a number of years we have claimed the distinction of being the largest bank headquartered in the South San Joaquin Valley. The Bank’s deposit accounts, which totaled $2.2 billion at September 30, 2019, are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to maximum insurable amounts.

Basis Of Presentation [Abstract]
Basis of Presentation	Note 2 – Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in a condensed format, and therefore do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. The information furnished in these interim statements reflects all adjustments that are, in the opinion of Management, necessary for a fair statement of the results for such periods. Such adjustments can generally be considered as normal and recurring unless otherwise disclosed in this Form 10‑Q. In preparing the accompanying financial statements, Management has taken subsequent events into consideration and recognized them where appropriate. The results of operations in the interim statements are not necessarily indicative of the results that may be expected for any other quarter, or for the full year. Certain amounts reported for 2018 have been reclassified to be consistent with the reporting for 2019. The interim financial information should be read in conjunction with the Company’s Annual Report on Form 10‑K for the year ended December 31, 2018, as filed with the Securities and Exchange Commission (the “SEC”).

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Current Accounting Developments	Note 3 – Current Accounting Developments In February 2016 the FASB issued ASU 2016‑02, Leases (Topic 842) . The intention of this standard is to increase the transparency and comparability around lease obligations. Previously unrecorded off-balance sheet obligations are now brought more prominently to light by presenting lease liabilities on the face of the balance sheet, accompanied by enhanced qualitative and quantitative disclosures in the notes to the financial statements. ASU 2016‑02 became effective for public business entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company has leases on 21 branch locations, an administrative office building, and three offsite ATM locations which are considered operating leases and were not previously reflected in our financial statements. Pursuant to ASU 2016‑02, on January 1, 2019 these lease agreements were recognized on our consolidated statement of condition as right-of-use assets totaling approximately $10 million, and corresponding lease liabilities. Please see Note 12 to the consolidated financial statements for more detailed disclosure information. In September 2016 the FASB issued ASU 2016‑13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which eliminates the probable initial recognition threshold for credit losses in current U.S. GAAP, and instead requires an organization to record a current estimate of all expected credit losses over the contractual term for financial assets carried at amortized cost. This is commonly referred to as the current expected credit losses (“CECL”) methodology. Expected credit losses for financial assets held at the reporting date will be measured based on historical experience, current conditions, and reasonable and supportable forecasts. Another change from existing U.S. GAAP involves the treatment of purchased credit deteriorated assets, which are more broadly defined than purchased credit impaired assets in current accounting standards. When such assets are purchased, institutions will estimate and record an allowance for credit losses that is added to the purchase price rather than being reported as a credit loss expense. Furthermore, ASU 2016‑13 updates the measurement of credit losses on available-for-sale debt securities, by mandating that institutions record credit losses on available-for-sale debt securities through an allowance for credit losses rather than the current practice of writing down securities for other-than-temporary impairment. ASU 2016‑13 will also require the enhancement of financial statement disclosures regarding estimates used in calculating credit losses. ASU 2016‑13 does not change the existing write-off principle in U.S. GAAP or current nonaccrual practices, nor does it change accounting requirements for loans held for sale or certain other financial assets which are measured at the lower of amortized cost or fair value. As a public business entity that is an SEC filer, ASU 2016‑13 becomes effective for the Company on January 1, 2020, although early application is permitted for 2019. On the effective date, institutions will apply the new accounting standard as follows: for financial assets carried at amortized cost, a cumulative-effect adjustment will be recognized on the balance sheet for any change in the related allowance for loan and lease losses generated by the adoption of the new standard; financial assets classified as purchased credit impaired assets prior to the effective date will be reclassified as purchased credit deteriorated assets as of the effective date, and will be grossed up for the related allowance for expected credit losses created as of the effective date; and, debt securities on which other-than-temporary impairment had been recognized prior to the effective date will transition to the new guidance prospectively with no change in their amortized cost basis. The Company is well under way with transition efforts. We have established an implementation team which is chaired by our Chief Credit Officer and includes the Company’s other executive officers, along with certain members of our credit administration and finance departments. Furthermore, after extensive discussion and due diligence, in 2018 we engaged a third-party vendor and purchased a specialized application to assist in our calculation of potential required reserves utilizing the CECL methodology and to help validate our current reserving methodology. While the ultimate impact cannot be definitively determined until the implementation date, a preliminary evaluation indicates that the provisions of ASU 2016‑13 will likely have a material impact on our consolidated financial statements, particularly the level of our allowance for credit losses and shareholders’ equity. Initial estimates are that our allowance for loan and lease losses could increase by 100% or more relative to current levels if we utilize the discounted cash flow methodology with forecasting. In January 2017 the FASB issued ASU 2017‑01, Business Combinations (Topic 805): Clarifying the Definition of a Business . Topic 805 specifies three elements of a business – inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a “set”) that is a business usually has outputs, outputs are not required. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs, for example, by integrating the acquired set with their own inputs and processes. This led many transactions to be accounted for as business combinations rather than asset purchases under legacy GAAP. The primary goal of ASU 2017‑01 is to narrow the definition of a business, and the guidance in this update provides a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This reduces the number of transactions that need to be further evaluated. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, and we implemented ASU 2017‑01 on a prospective basis effective January 1, 2018. This update affected the accounting treatment used for our branch deposit purchase in the second quarter of 2018, and we expect that it will also impact the way we account for certain branch acquisitions in future periods if the opportunity for such arises. In January 2017 the FASB issued ASU 2017‑04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment . This guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation, and goodwill impairment will simply be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The same one-step impairment test will be applied to goodwill at all reporting units, even those with zero or negative carrying amounts. Entities will be required to disclose the amount of goodwill at reporting units with zero or negative carrying amounts. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2019. We have not been required to record any goodwill impairment to date, and after a preliminary review do not expect that this guidance would require us to do so given current circumstances. Nevertheless, we will continue to evaluate ASU 2017‑04 to more definitely determine its potential impact on the Company’s consolidated financial position, results of operations and cash flows. In March 2017 the FASB issued ASU 2017‑08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310‑20): Premium Amortization on Purchased Callable Debt Securities . The amendments in this update shortened the amortization period for certain callable debt securities held at a premium, by requiring the premium to be amortized to the earliest call date. Under previous guidance, the premium on a callable debt security was generally amortized as an adjustment to yield over the contractual life of the instrument, with any unamortized premium recorded as a loss in earnings upon the debtor’s exercise of a call provision. Under ASU 2017‑08, because the premium is amortized to the earliest call date, entities no longer recognize a loss in earnings if a debt security is called prior to the contractual maturity date. The amendments did not require an accounting change for securities held at a discount; discounts continue to be amortized as an adjustment to yield over the contractual life of the debt instrument. ASU 2017‑08 became effective for public business entities, including the Company, for fiscal years and interim periods within those fiscal years beginning after December 15, 2018. To apply ASU 2017‑08, entities were required to use a modified retrospective approach, with the cumulative-effect adjustment recognized to retained earnings at the beginning of the period of adoption. The Company adopted ASU 2017‑08 effective January 1, 2019 with no material impact on our financial statements or operations. In August 2018 the FASB issued ASU 2018‑13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement, as part of its disclosure framework project. Pursuant to this guidance, disclosures that will no longer be required include the following: transfers between Level 1 and Level 2 of the fair value hierarchy; transfers in and out of Level 3 for nonpublic entities, as well as purchases and issuances and the Level 3 roll forward; a company’s policy for determining when transfers between any of the three levels have occurred; the valuation processes used for Level 3 measurements; and, the changes in unrealized gains or losses presented in earnings for Level 3 instruments held at the balance sheet date for nonpublic entities. The following are additional disclosure requirements: for public entities, the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 instruments held at the balance sheet date; for public entities, the range and weighted average of significant unobservable inputs used for Level 3 measurements, although for certain unobservable inputs the entity will be allowed to disclose other quantitative information in place of the weighted average to the extent that it would be a more reasonable and rational method to reflect the distribution of unobservable inputs; for nonpublic entities, some form of quantitative information about significant unobservable inputs used in Level 3 fair value measurements; and, for certain investments in entities that calculate the net asset value, disclosures will be required about the timing of liquidation and redemption restrictions lapsing if the latter has been communicated to the reporting entity. The guidance also clarifies that the Level 3 measurement uncertainty disclosure should communicate information about the uncertainty at the balance sheet date. ASU 2018‑13 is effective for all entities in fiscal years beginning after December 15, 2019, including interim periods. Early adoption is permitted. In addition, an entity may early adopt any of the removed or modified disclosures immediately and delay adoption of the new disclosures until the effective date. The Company has evaluated the potential impact of this guidance, and does not expect the adoption of ASU 2018-13 to have a material impact on our financial statements or operations. In May 2019, the FASB issued ASU 2019-05, Financial Instruments—Credit Losses (Topic 326) , which provides transition relief for entities adopting ASU 2016-13. ASU 2019-05 amends ASU 2016-13 to allow companies to irrevocably elect, upon adoption of ASU 2016-13, the fair value option on financial instruments that (1) were previously recorded at amortized cost and (2) are within the scope of ASC 326-20 if the instruments are eligible for the fair value option under ASC 825-10. An entity will apply the amendments in this update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). A prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized before the effective date, in order to maintain the same amortized cost basis before and after the effective date of this update. Amounts previously recognized in accumulated other comprehensive income as of the date of adoption that relate to improvements in cash flows expected to be collected should continue to be accreted into income over the remaining life of the asset. Recoveries of amounts previously written off relating to improvements in cash flows after the date of adoption should be recorded in earnings when received. The fair value option election does not apply to held-to-maturity debt securities. Entities are required to make this election on an instrument-by-instrument basis. For public business entities that are SEC filers, including the Company, the amendments in ASU 2019-05 are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company has evaluated the potential impact of this guidance, and does not expect the adoption of ASU 2019-05 to have a material impact on our financial statements or operations.

Share Based Compensation [Abstract]
Share Based Compensation	Note 4 – Share Based Compensation On March 16, 2017 the Company’s Board of Directors approved and adopted the 2017 Stock Incentive Plan (the “2017 Plan”), which became effective May 24, 2017, the date approved by the Company’s shareholders. The 2017 Plan replaced the Company’s 2007 Stock Incentive Plan (the “2007 Plan”), which expired by its own terms on March 15, 2017. Options to purchase 327,610 shares that were granted under the 2007 Plan were still outstanding as of September 30, 2019 and remain unaffected by that plan’s expiration. The 2017 Plan provides for the issuance of both “incentive” and “nonqualified” stock options to officers and employees, and of “nonqualified” stock options to non-employee directors and consultants of the Company. The 2017 Plan also provides for the issuance of restricted stock awards to these same classes of eligible participants, although no restricted stock awards have ever been issued by the Company. The total number of shares of the Company’s authorized but unissued stock reserved for issuance pursuant to awards under the 2017 Plan was initially 850,000 shares, and the number remaining available for grant as of September 30, 2019 was 669,800. The potential dilutive impact of unexercised stock options is discussed below in Note 5, Earnings per Share. Pursuant to FASB’s standards on stock compensation, the value of each stock option is reflected in our income statement as employee compensation or directors’ expense by amortizing its grant date fair value over the vesting period of the option. The Company utilizes a Black-Scholes model to determine grant date fair values. A pre-tax charge of $112,000 was reflected in the Company’s income statement during the third quarter of 2019 and $100,000 was charged during the third quarter of 2018, as expense related to stock options. For the first nine months, the charges totaled $379,000 in 2019 and $274,000 in 2018.

Earnings Per Share [Abstract]
Earnings per Share	Note 5 – Earnings per Share The computation of earnings per share, as presented in the Consolidated Statements of Income, is based on the weighted average number of shares outstanding during each period. There were 15,318,580 weighted average shares outstanding during the third quarter of 2019 and 15,267,587 during the third quarter of 2018, while there were 15,320,041 weighted average shares outstanding during the first nine months of 2019 and 15,251,746 during the first nine months of 2018. Diluted earnings per share calculations include the effect of the potential issuance of common shares, which for the Company is limited to shares that would be issued on the exercise of “in-the-money” stock options. For the third quarter of 2019, calculations under the treasury stock method resulted in the equivalent of 116,208 shares being added to basic weighted average shares outstanding for purposes of determining diluted earnings per share, while a weighted average of 261,137 stock options were excluded from the calculation because they were underwater and thus anti-dilutive. For the third quarter of 2018 the equivalent of 176,819 shares were added in calculating diluted earnings per share, while 105,800 anti-dilutive stock options were not factored into the computation. Likewise, for the first nine months of 2019 the equivalent of 129,299 shares were added to basic weighted average shares outstanding in calculating diluted earnings per share and a weighted average of 239,714 options that were anti-dilutive for the period were not included, compared to the addition of the equivalent of 176,719 shares and non-inclusion of 105,800 anti-dilutive options in calculating diluted earnings per share for first nine months of 2018.

Comprehensive Income	Note 6 – Comprehensive Income As presented in the Consolidated Statements of Comprehensive Income, comprehensive income includes net income and other comprehensive income. The Company’s only source of other comprehensive income is unrealized gains and losses on available-for-sale investment securities. Investment gains or losses that were realized and reflected in net income of the current period, which had previously been included in other comprehensive income as unrealized holding gains or losses in the period in which they arose, are considered to be reclassification adjustments that are excluded from other comprehensive income in the current period.

Financial Instruments with Off Balance Sheet Risk [Abstract]
Financial Instruments with Off-Balance-Sheet Risk	Note 7 – Financial Instruments with Off-Balance-Sheet Risk The Company is a party to financial instruments with off‑balance‑sheet risk in the normal course of business. Those financial instruments currently consist of unused commitments to extend credit and standby letters of credit. They involve, to varying degrees, elements of risk in excess of the amount recognized in the balance sheet. The Company’s exposure to credit loss in the event of nonperformance by counterparties for commitments to extend credit and letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and issuing letters of credit as it does for originating loans included on the balance sheet. The following financial instruments represent off‑balance‑sheet credit risk (dollars in thousands): September 30, 2019 December 31, 2018 Commitments to extend credit $ 503,375 $ 781,987 Standby letters of credit $ 9,143 $ 8,966 Commitments to extend credit consist primarily of the unused or unfunded portions of the following: home equity lines of credit; commercial real estate construction loans, where disbursements are made over the course of construction; commercial revolving lines of credit; mortgage warehouse lines of credit; unsecured personal lines of credit; and formalized (disclosed) deposit account overdraft lines. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many commitments are expected to expire without being drawn upon, the unused portions of committed amounts do not necessarily represent future cash requirements. Standby letters of credit are issued by the Company to guarantee the performance of a customer to a third party, and the credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. At September 30, 2019, the Company was also utilizing a letter of credit in the amount of $105 million issued by the Federal Home Loan Bank on the Company’s behalf as security for certain deposits and to facilitate certain credit arrangements with the Company’s customers. That letter of credit is backed by loans which are pledged to the FHLB by the Company.

Fair Value Disclosures [Abstract]
Fair Value Disclosures and Reporting, the Fair Value Option and Fair Value Measurements	Note 8 – Fair Value Disclosures and Reporting, the Fair Value Option and Fair Value Measurements FASB’s standards on financial instruments, and on fair value measurements and disclosures, require public business entities to disclose in their financial statement footnotes the estimated fair values of financial instruments. In addition to disclosure requirements, FASB’s standard on investments requires that our debt securities that are classified as available for sale and any equity securities which have readily determinable fair values be measured and reported at fair value in our statement of financial position. Certain impaired loans are also reported at fair value, as explained in greater detail below, and foreclosed assets are carried at the lower of cost or fair value. FASB’s standard on financial instruments permits companies to report certain other financial assets and liabilities at fair value, but we have not elected the fair value option for any of those financial instruments. Fair value measurement and disclosure standards also establish a framework for measuring fair values. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants on the measurement date. Further, the standards establish a fair value hierarchy that encourages an entity to maximize the use of observable inputs and limit the use of unobservable inputs when measuring fair values. The standards describe three levels of inputs that may be used to measure fair values: · Level 1 : Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. · Level 2 : Significant observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data. · Level 3 : Significant unobservable inputs that reflect a company’s own assumptions about the factors that market participants would likely consider in pricing an asset or liability. Fair value estimates are made at a specific point in time based on relevant market data and information about the financial instruments. Fair value disclosures for deposits include demand deposits, which are by definition equal to the amount payable on demand at the reporting date. Fair value calculations for loans and leases reflect exit pricing, and incorporate our assumptions with regard to the impact of prepayments on future cash flows and credit quality adjustments based on risk characteristics of various financial instruments, among other things. Since the estimates are subjective and involve uncertainties and matters of significant judgment they cannot be determined with precision, and changes in assumptions could significantly alter the fair values presented. Estimated fair values for the Company’s financial instruments are as follows, as of the dates noted: Fair Value of Financial Instruments (dollars in thousands, unaudited) September 30, 2019 Fair Value Measurements Carrying Quoted Prices in Significant Significant Total Financial assets: Cash and cash equivalents $ 80,689 $ 80,689 $ — $ — $ 80,689 Investment securities available for sale 599,906 — 599,906 — 599,906 Loans and leases, net held for investment 1,787,406 — 1,807,104 — 1,807,104 Collateral dependent impaired loans 2,000 — 2,000 — 2,000 Financial liabilities: Deposits 2,196,207 685,528 1,510,840 — 2,196,368 Repurchase agreements 25,157 25,157 — — 25,157 Short term borrowings 42,200 — 42,200 — 42,200 Subordinated debentures 34,901 — 31,024 — 31,024 December 31, 2018 Fair Value Measurements Carrying Quoted Prices in Significant Significant Total Financial assets: Cash and cash equivalents $ 74,132 $ 74,132 $ — $ — $ 74,132 Investment securities available for sale 560,479 — 560,479 — 560,479 Loans and leases, net held for investment 1,724,575 — 1,707,463 — 1,707,463 Collateral dependent impaired loans 205 — 205 — 205 Financial liabilities: Deposits 2,116,340 662,527 1,453,048 — 2,115,575 Repurchase agreements 16,359 16,359 — — 16,359 Short term borrowings 56,100 — 56,100 — 56,100 Subordinated debentures 34,767 — 30,311 — 30,311 For financial asset categories that were carried on our balance sheet at fair value as of September 30, 2019 and December 31, 2018, the Company used the following methods and significant assumptions: · Investment securities : Fair values are determined by obtaining quoted prices on nationally recognized securities exchanges or by matrix pricing, which is a mathematical technique used widely in the industry to value debt securities by relying on their relationship to other benchmark quoted securities. · Collateral-dependent impaired loans : Collateral-dependent impaired loans are carried at fair value when it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the original loan agreement and the loan has been written down to the fair value of its underlying collateral, net of expected disposition costs where applicable. · Foreclosed assets : Repossessed real estate (known as other real estate owned, or “OREO”) and other foreclosed assets are carried at the lower of cost or fair value. Fair value is the appraised value less expected selling costs for OREO and some other assets such as mobile homes; fair values for any other foreclosed assets are represented by estimated sales proceeds as determined using reasonably available sources. Foreclosed assets for which appraisals can be feasibly obtained are periodically measured for impairment using updated appraisals. Fair values for other foreclosed assets are adjusted as necessary, subsequent to a periodic re-evaluation of expected cash flows and the timing of resolution. If impairment is determined to exist, the book value of a foreclosed asset is immediately written down to its estimated impaired value through the income statement, thus the carrying amount is equal to the fair value and there is no valuation allowance. Assets reported at fair value on a recurring basis are summarized below: Fair Value Measurements – Recurring (dollars in thousands, unaudited) Fair Value Measurements at September 30, 2019, using Quoted Prices in Significant Significant Total Realized Securities: U.S. government agencies $ — $ 14,445 $ — $ 14,445 $ — Mortgage-backed securities — 411,803 — 411,803 — State and political subdivisions — 173,658 — 173,658 — Total available-for-sale securities $ — $ 599,906 $ — $ 599,906 $ — Fair Value Measurements at December 31, 2018, using Quoted Prices in Significant Significant Total Realized Securities: U.S. government agencies $ — $ 15,212 $ — $ 15,212 $ — Mortgage-backed securities — 404,733 — 404,733 — State and political subdivisions — 140,534 — 140,534 — Total available-for-sale securities $ — $ 560,479 $ — $ 560,479 $ — Assets reported at fair value on a nonrecurring basis are summarized below: Fair Value Measurements – Nonrecurring (dollars in thousands, unaudited) Fair Value Measurements at September 30, 2019, using Quoted Prices in Significant Significant Total Impaired loans Real estate: 1-4 family residential construction $ — $ — $ — $ — Other construction/land — — — — 1-4 family - closed-end — — — — Equity lines — — — — Multi-family residential — — — — Commercial real estate - owner occupied — 91 — 91 Commercial real estate - non-owner occupied — 1,909 — 1,909 Farmland — — — — Total real estate — 2,000 — 2,000 Agricultural — — — — Commercial and industrial — — — — Consumer loans — — — — Total impaired loans $ — $ 2,000 $ — $ 2,000 Foreclosed assets $ — $ 762 $ — $ 762 Total assets measured on a nonrecurring basis $ — $ 2,762 $ — $ 2,762 Fair Value Measurements at December 31, 2018, using Quoted Prices in Significant Significant Total Impaired loans Real estate: 1-4 family residential construction $ — $ — $ — $ — Other construction/land — 27 — 27 1-4 family - closed-end — — — — Equity lines — 12 — 12 Multi-family residential — — — — Commercial real estate - owner occupied — — — — Commercial real estate - non-owner occupied — — — — Farmland — — — — Total real estate — 39 — 39 Agricultural — — — — Commercial and industrial — 119 — 119 Consumer loans — 47 — 47 Total impaired loans $ — $ 205 $ — $ 205 Foreclosed assets $ — $ 1,082 $ — $ 1,082 Total assets measured on a nonrecurring basis $ — $ 1,287 $ — $ 1,287 The table above includes collateral-dependent impaired loan balances for which a specific reserve has been established or on which a write-down has been taken. Information on the Company’s total impaired loan balances and specific loss reserves associated with those balances is included in Note 11 below, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations in the “Nonperforming Assets” and “Allowance for Loan and Lease Losses” sections. The unobservable inputs are based on Management’s best estimates of appropriate discounts in arriving at fair market value. Adjusting any of those inputs could result in a significantly lower or higher fair value measurement. For example, an increase or decrease in actual loss rates would create a directionally opposite change in the fair value of unsecured impaired loans.

Investments, Debt and Equity Securities [Abstract]
Investments	Note 9 – Investments Investment Securities Although the Company currently has the intent and the ability to hold the securities in its investment portfolio to maturity, the securities are all marketable and are classified as “available for sale” to allow maximum flexibility with regard to interest rate risk and liquidity management. Pursuant to FASB’s guidance on accounting for debt and equity securities, available for sale securities are carried on the Company’s financial statements at their estimated fair market values, with monthly tax-effected “mark-to-market” adjustments made vis-à-vis accumulated other comprehensive income in shareholders’ equity. The amortized cost and estimated fair value of available-for-sale investment securities are as follows: Amortized Cost And Estimated Fair Value (dollars in thousands, unaudited) September 30, 2019 Amortized Gross Gross Estimated Fair U.S. government agencies $ 14,408 $ 168 $ (131) $ 14,445 Mortgage-backed securities 409,922 3,483 (1,602) 411,803 State and political subdivisions 167,213 6,488 (43) 173,658 Total securities $ 591,543 $ 10,139 $ (1,776) $ 599,906 December 31, 2018 Amortized Gross Gross Estimated Fair U.S. government agencies $ 15,553 $ 12 $ (353) $ 15,212 Mortgage-backed securities 414,208 398 (9,873) 404,733 State and political subdivisions 140,181 1,206 (853) 140,534 Total securities $ 569,942 $ 1,616 $ (11,079) $ 560,479 At September 30, 2019 and December 31, 2018, the Company had 240 securities and 552 securities, respectively, with gross unrealized losses. Management has evaluated those securities as of the respective dates, and does not believe that any of the unrealized losses are other than temporary.

The largest exposure to any single municipality or agency was a combined $2.2 million (fair value) in general obligation bonds issued by the Lindsay (CA) Unified School District. The Company’s investments in bonds issued by states, municipalities and political subdivisions are evaluated in accordance with Supervision and Regulation Letter 12‑15 issued by the Board of Governors of the Federal Reserve System, “Investing in Securities without Reliance on Nationally Recognized Statistical Rating Organization Ratings,” and other regulatory guidance. Credit ratings are considered in our analysis only as a guide to the historical default rate associated with similarly-rated bonds. There have been no significant differences in our internal analyses compared with the ratings assigned by the third party credit rating agencies.

The primary investment return comes from tax credits that flow through to investors. Because rent levels are lower than standard market rents and the projects are generally highly leveraged, each project also typically generates tax-deductible operating losses that are allocated to the limited partners for tax purposes. The Company made investment commitments to nine different LIHTC fund limited partnerships from 2001 through 2017, all of which were California-focused funds that help the Company meet its obligations under the Community Reinvestment Act. We utilize the cost method of accounting for our LIHTC fund investments, under which we initially record on our balance sheet an asset that represents the total cash expected to be invested over the life of the partnership. Any commitments or contingent commitments for future investment are reflected as a liability. The income statement reflects tax credits and any other tax benefits from these investments “below the line” within our income tax provision, while the initial book value of the investment is amortized on a straight-line basis as an offset to noninterest income, over the time period in which the tax credits and tax benefits are expected to be received. As of September 30, 2019 our total LIHTC investment book balance was $4.6 million, which includes $1.4 million in remaining commitments for additional capital contributions. There were $404,000 in tax credits derived from our LIHTC investments that were recognized during the nine months ended September 30, 2019, and amortization expense of $1.351 million associated with those investments was netted against pre-tax noninterest income for the same time period. Our LIHTC investments are evaluated annually for potential impairment, and we have concluded that the carrying value of the investments is stated fairly and is not impaired.

Credit Quality and Nonperforming Assets [Abstract]
Credit Quality and Nonperforming Assets	Note 10 – Credit Quality and Nonperforming Assets Credit Quality Classifications The Company monitors the credit quality of loans on a continuous basis using the regulatory and accounting classifications of pass, special mention, substandard and impaired to characterize the associated credit risk. Balances classified as “loss” are immediately charged off. The Company conforms to the following definitions for its risk classifications: · Pass : Larger non-homogeneous loans not meeting the risk rating definitions below, and smaller homogeneous loans that are not assessed on an individual basis. · Special mention : Loans which have potential issues that deserve the close attention of Management. If left uncorrected, those potential weaknesses could eventually diminish the prospects for full repayment of principal and interest according to the contractual terms of the loan agreement, or could result in deterioration of the Company’s credit position at some future date. · Substandard : Loans that have at least one clear and well-defined weakness that could jeopardize the ultimate recoverability of all principal and interest, such as a borrower displaying a highly leveraged position, unfavorable financial operating results and/or trends, uncertain repayment sources or an otherwise deteriorated financial condition. · Impaired : A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impaired loans include all nonperforming loans and restructured troubled debt (“TDRs”). A TDR may be nonperforming or performing, depending on its accrual status and the demonstrated ability of the borrower to comply with restructured terms (see “Troubled Debt Restructurings” section below for additional information on TDRs). Credit quality classifications for the Company’s loan balances were as follows, as of the dates indicated: Credit Quality Classifications (dollars in thousands, unaudited) September 30, 2019 Pass Special Substandard Impaired Total Real estate: 1-4 family residential construction $ 115,821 $ — $ — $ — $ 115,821 Other construction/land 92,008 704 — 405 93,117 1-4 family - closed end 204,871 1,618 424 3,814 210,727 Equity lines 44,352 1,971 89 4,795 51,207 Multi-family residential 51,945 — — 357 52,302 Commercial real estate - owner occupied 310,413 5,751 4,324 2,050 322,538 Commercial real estate - non-owner occupied 412,689 1,390 526 2,819 417,424 Farmland 143,396 1,060 137 25 144,618 Total real estate 1,375,495 12,494 5,500 14,265 1,407,754 Agricultural 39,165 9,934 — 6 49,105 Commercial and industrial 101,108 13,162 657 810 115,737 Mortgage warehouse 216,913 — — — 216,913 Consumer loans 7,351 76 18 706 8,151 Total gross loans and leases $ 1,740,032 $ 35,666 $ 6,175 $ 15,787 $ 1,797,660 December 31, 2018 Pass Special Substandard Impaired Total Real estate: 1-4 family residential construction $ 105,676 $ — $ — $ — $ 105,676 Other construction/land 108,304 231 — 488 109,023 1-4 family - closed end 230,022 1,861 1,310 3,632 236,825 Equity lines 49,346 2,194 64 4,716 56,320 Multi-family residential 54,504 — — 373 54,877 Commercial real estate - owner occupied 292,886 4,192 3,021 1,225 301,324 Commercial real estate - non-owner occupied 429,835 2,730 4,354 1,425 438,344 Farmland 148,680 1,073 146 1,642 151,541 Total real estate 1,419,253 12,281 8,895 13,501 1,453,930 Agricultural 48,517 580 — 6 49,103 Commercial and industrial 110,413 15,686 377 1,744 128,220 Mortgage warehouse 91,813 — — — 91,813 Consumer loans 7,851 151 39 821 8,862 Total gross loans and leases $ 1,677,847 $ 28,698 $ 9,311 $ 16,072 $ 1,731,928 Past Due and Nonperforming Assets Nonperforming assets are comprised of loans for which the Company is no longer accruing interest, and foreclosed assets. The Company’s foreclosed assets can include mobile homes and/or OREO, which consists of commercial and/or residential real estate properties acquired by foreclosure or similar means that the Company is offering or will offer for sale. Foreclosed assets totaled $762,000 at September 30, 2019, and $1.082 million at December 31, 2018. Gross nonperforming loans totaled $6.719 million at September 30, 2019 and $5.156 million at December 31, 2018. Loans and leases are classified as nonperforming when reasonable doubt surfaces with regard to the ability of the Company to collect all principal and interest. At that point, we stop accruing interest on the loan or lease in question and reverse any previously-recognized interest to the extent that it is uncollected or associated with interest-reserve loans. Any asset for which principal or interest has been in default for 90 days or more is also placed on non-accrual status even if interest is still being received, unless the asset is both well secured and in the process of collection.

(2) Included in total financing receivables Troubled Debt Restructurings A loan that is modified for a borrower who is experiencing financial difficulty is classified as a troubled debt restructuring if the modification constitutes a concession. At September 30, 2019, the Company had a total of $9.9 48 million in TDRs, including $880,000 in TDRs that were on non-accrual status. Generally, a non-accrual loan that has been modified as a TDR remains on non-accrual status for a period of at least six months to demonstrate the borrower’s ability to comply with the modified terms. However, performance prior to the modification, or significant events that coincide with the modification, could result in a loan’s return to accrual status after a shorter performance period or even at the time of loan modification. Regardless of the period of time that has elapsed, if the borrower’s ability to meet the revised payment schedule is uncertain then the loan will be kept on non-accrual status. Moreover, a TDR is generally considered to be in default when it appears that the customer will not likely be able to repay all principal and interest pursuant to restructured terms. The Company may agree to different types of concessions when modifying a loan or lease.

The company had no finance receivables modified as TDRs within the previous twelve months that defaulted or were charged off during the nine-month periods ended September 30, 2019 and 2018. Purchased Credit Impaired Loans The Company may acquire loans which show evidence of credit deterioration since origination. These purchased credit impaired (“PCI”) loans are recorded at the amount paid, since there is no carryover of the seller’s allowance for loan losses. Potential losses on PCI loans subsequent to acquisition are recognized by an increase in the allowance for loan losses. PCI loans are accounted for individually or are aggregated into pools of loans based on common risk characteristics. The Company projects the amount and timing of expected cash flows, and expected cash receipts in excess of the amount paid for any such loans are recorded as interest income over the remaining life of the loan or pool of loans (accretable yield). The excess of contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Expected cash flows are periodically re-evaluated throughout the life of the loan or pool of loans. If the present value of the expected cash flows is determined at any time to be less than the carrying amount, a reserve is recorded. If the present value of the expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. Our acquisition of Santa Clara Valley Bank in 2014 included certain loans which have shown evidence of credit deterioration since origination, and for which it was probable at acquisition that all contractually required payments would not be collected. The carrying amount and unpaid principal balance of those PCI loans was as follows, as of the dates indicated: Purchased Credit Impaired Loans: (dollars in thousands, unaudited) September 30, 2019 Unpaid Principal Balance Carrying Value Real estate secured $ 91 $ — Total purchased credit impaired loans $ 91 $ — December 31, 2018 Unpaid Principal Balance Carrying Value Real estate secured $ 103 $ — Total purchased credit impaired loans $ 103 $ — An allowance for loan losses totaling $91,000 was allocated for PCI loans as of September 30, 2019, as compared to $103,000 at December 31, 2018. There was no discount accretion recorded on PCI loans during the nine months ended September 30, 2019.

Provision for Loan and Lease Losses [Abstract]
Allowance for Loan and Lease Losses	Note 11 – Allowance for Loan and Lease Losses The Company’s allowance for loan and lease losses, a contra-asset, is established through a provision for loan and lease losses. The allowance is maintained at a level that is considered adequate to absorb probable losses on certain specifically identified impaired loans, as well as probable incurred losses inherent in the remaining loan portfolio. Specifically identifiable and quantifiable losses are immediately charged off against the allowance; recoveries are generally recorded only when cash payments are received subsequent to the charge off. We employ a systematic methodology, consistent with FASB guidelines on loss contingencies and impaired loans, for determining the appropriate level of the allowance for loan and lease losses and adjusting it to that level at least quarterly. Pursuant to our methodology, impaired loans and leases are individually analyzed and a criticized asset action plan is completed specifying the financial status of the borrower and, if applicable, the characteristics and condition of collateral and any associated liquidation plan. A specific loss allowance is created for each impaired loan, if necessary. The following tables disclose the unpaid principal balance, recorded investment, average recorded investment, and interest income recognized for impaired loans on our books as of the dates indicated. Balances are shown by loan type, and are further broken out by those that required an allowance and those that did not, with the associated allowance disclosed for those that required such. Included in the valuation allowance for impaired loans shown in the tables below are specific reserves allocated to TDRs, totaling $1.063 million at September 30, 2019 and $1.048 million at December 31, 2018.

(2) Principal balance on Company’s books, less any direct charge offs. (3) Interest income is recognized on performing balances on a regular accrual basis . The specific loss allowance for an impaired loan generally represents the difference between the book value of the loan and either the fair value of underlying collateral less estimated disposition costs, or the loan’s net present value as determined by a discounted cash flow analysis. The discounted cash flow approach is typically used to measure impairment on loans for which it is anticipated that repayment will be provided from cash flows other than those generated solely by the disposition or operation of underlying collateral. However, historical loss rates may be used by the Company to determine a specific loss allowance if those rates indicate a higher potential reserve need than the discounted cash flow analysis. Any change in impairment attributable to the passage of time is accommodated by adjusting the loss allowance accordingly. For loans where repayment is expected to be provided by the disposition or operation of the underlying collateral, impairment is measured using the fair value of the collateral. If the collateral value, net of the expected costs of disposition, is less than the loan balance, then a specific loss reserve is established for the shortfall in collateral coverage. If the discounted collateral value is greater than or equal to the loan balance, no specific loss reserve is required. At the time a collateral-dependent loan is designated as nonperforming, a new appraisal is ordered and typically received within 30 to 60 days if a recent appraisal is not already available. We generally use external appraisals to determine the fair value of the underlying collateral for nonperforming real estate loans, although the Company’s licensed staff appraisers may update older appraisals based on current market conditions and property value trends. Until an updated appraisal is received, the Company uses the existing appraisal to determine the amount of the specific loss allowance that may be required. The specific loss allowance is adjusted, as necessary, once a new appraisal is received. Updated appraisals are generally ordered at least annually for collateral-dependent loans that remain impaired, and current appraisals were available or in process for 97% of the Company’s impaired real estate loan balances at September 30, 2019. Furthermore, the Company analyzes collateral-dependent loans on at least a quarterly basis, to determine if any portion of the recorded investment in such loans can be identified as uncollectible and would therefore constitute a confirmed loss. All amounts deemed to be uncollectible are promptly charged off against the Company’s allowance for loan and lease losses, with the loan then carried at the fair value of the collateral, as appraised, less estimated costs of disposition if applicable. Once a charge-off or write-down is recorded, it will not be restored to the loan balance on the Company’s accounting books. Our methodology also provides for the establishment of a “general” allowance for probable incurred losses inherent in loans and leases that are not impaired. Unimpaired loan balances are segregated by credit quality, and are then evaluated in pools with common characteristics. At the present time, pools are based on the same segmentation of loan types presented in our regulatory filings. While this methodology utilizes historical loss data and other measurable information, the credit classification of loans and the establishment of the allowance for loan and lease losses are both to some extent based on Management’s judgment and experience. 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. Quantitative information includes our historical loss experience, delinquency and charge-off trends, and current collateral values. Qualitative factors include the general economic environment in our markets and, in particular, the condition of the agricultural industry and other key industries. Lending policies and procedures (including underwriting standards), the experience and abilities of lending staff, the quality of loan review, credit concentrations (by geography, loan type, industry and collateral type), the rate of loan portfolio growth, and changes in legal or regulatory requirements are additional factors that are considered. The total general reserve established for probable incurred losses on unimpaired loans was $9.141 million at September 30, 2019. There were no material changes to the methodology used to determine our allowance for loan and lease losses during the three months ended September 30, 2019, although as outlined in Note 3 to the consolidated financial statements we will substantially update our methodology upon the adoption of ASU 2016‑13 on January 1, 2020. Moreover, we will continue to enhance our methodology as needed in order to comply with regulatory and accounting requirements, keep pace with the size and complexity of our loan and lease portfolio, and respond to pressures created by external forces. We engage outside firms on a regular basis to assess our methodology and perform independent credit reviews of our loan and lease portfolio. In addition, the FDIC and the California DBO review the allowance for loan and lease losses as an integral part of their audit and examination processes. Management believes that the current methodology is appropriate given our size and level of complexity.

Leases [Abstract]
Operating Leases	Note 12 – Operating Leases We lease space under non-cancelable operating leases for 21 branch locations, three off-site ATM locations, one administrative building and a warehouse. Many of our leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common-area or other maintenance costs). Payments for taxes and insurance as well as non-lease components are not included in the accounting of the lease component, but are separately accounted for in occupancy expense. The Company recognized lease expense of $557 thousand and $1.652 million for the three and nine month periods ended September 30, 2019, respectively. Lease expense for the three and nine month periods ended September 30, 2018, prior to the adoption of ASU 2016‑02, was $567 thousand and $1.745 million, respectively. Most leases include one or more renewal options available to exercise. The exercise of lease renewal options is typically at the Company’s sole discretion; therefore, the majority of renewals to extend the lease terms are not included in our right-of-use assets and lease liabilities as they are not reasonably certain of exercise. We regularly evaluate the renewal options and when they are reasonably certain of exercise, we include the renewal period in our lease term. As most of our leases do not provide an implicit rate, we used our incremental borrowing rate in determining the present value of the lease payments. There were no sale and leaseback transactions, leveraged leases, or lease transactions with related parties during the nine months ended September 30, 2019. At September 30, 2019, the Company’s right-of-use assets and operating lease liabilities were $8.677 million and $9.281 million, respectively. The weighted average remaining lease term for the lease liabilities was 5.0 years, and the weighted average discount rate of remaining payments was 5.5 percent. There were no lease liabilities from new right-of-use assets obtained during the nine months ended September 30, 2019. Cash paid on operating leases was $1.055 million for the nine months ended September 30, 2019. Maturities of our lease liabilities for all operating leases are as follows (dollars in thousands, unaudited): Maturities of Lease Liabilities 2019 (1) $ 550 2020 2,227 2021 2,013 2022 1,567 2023 1,119 Thereafter 3,939 Total 11,415 Less: present value discount (2,134) Lease liability (2) $ 9,281 (1) Contractual maturities for the three months remaining in 2019.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Note 13 – Revenue Recognition. The Company utilizes the guidance found in ASU 2014‑09, Revenue from Contracts with Customers (ASC 606), when accounting for certain noninterest income. The core principle of this guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Sufficient information should be provided to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company’s revenue streams that are within the scope of and accounted for under Topic 606 include service charges on deposit accounts, debit card interchange fees, and fees levied for other services the Company provides its customers. The guidance does not apply to revenue associated with financial instruments such as loans and investments, and other noninterest income such as loan servicing fees and earnings on bank-owned life insurance, which are accounted for on an accrual basis under other provisions of GAAP. In total, approximately 19% of the Company’s noninterest revenue was outside of the scope of the ASC 606 for the nine months ended September 30, 2019. All of the company’s revenue from contracts within the scope of ASC 606 is recognized as noninterest income. The following table presents the Company’s sources of noninterest income for the three- and nine-month periods ended September 30, 2019 and 2018. Items outside the scope of ASC 606 are noted as such (dollars in thousands, unaudited).

Revenue streams are not related to contract with customers and are accounted for on an accrual basis under other provisions of GAAP. With regard to noninterest income associated with customer contracts, the Company has determined that transaction prices are fixed and performance obligations are satisfied as services are rendered, thus there is little or no judgment involved in the timing of revenue recognition under contracts that are within the scope of ASC 606.
