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 March 31, 2017, the Company’s only other subsidiaries were Sierra Statutory Trust II, Sierra Capital Trust III, and Coast Bancorp Statutory Trust II, which exist 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 full range of retail and commercial banking services in California’s South San Joaquin Valley and neighboring communities, the Central Coast, Ventura County, and Santa Clarita. 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 three whole-bank acquisitions: Sierra National Bank in 2000, Santa Clara Valley Bank in 2014, and Coast National Bank in July of 2016. The Bank now operates 34 full-service branches, a loan production office, and an online branch, and maintains ATMs at all branch locations and seven non-branch locations. Our most recent branching activity occurred in the first quarter of 2017, with a de novo branch opened on California Avenue in Bakersfield and our Paso Robles branch relocated to a superior site in reasonably close proximity to the previous location. The Company plans to expand even further in 2017 with the acquisition of OCB Bancorp, the holding company for Ojai Community Bank (see Note 13 to the financial statements, Recent Developments, for more details on the proposed acquisition), and we have also received regulatory approvals for a de novo branch in Pismo Beach, California, although the timing for that branch opening remains uncertain. In addition to our stand-alone offices the Bank has specialized lending units which include a real estate industries center, an agricultural credit center, and an SBA lending unit. We were $2.0 billion in total assets as of March 31, 2017, and for the past several years have claimed the distinction of being the largest bank headquartered in the South San Joaquin Valley. The Bank’s deposit accounts, which totaled over $1.7 billion at March 31, 2017, are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to maximum insurable amounts.

Share-based Compensation [Abstract]
Share Based Compensation	Note 5 – 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 becomes effective May 24, 2017 subject to the approval of the Company’s shareholders. The 2017 Plan will replace the Company’s 2007 Stock Incentive Plan (the “2007 Plan”), which expired by its own terms on March 15, 2017. Options to purchase 503,020 850,000 Pursuant to FASB’s standards on stock compensation, the value of each stock option granted is reflected in our income statement as employee compensation or directors’ expense by amortizing its grant date fair value over the vesting period for options with graded vesting, or by expensing its fair value as of the grant date in the case of immediately vested options. The Company is utilizing the Black-Scholes model to value stock options, and the “multiple option” approach is used to allocate the resulting valuation to actual expense. Under the multiple option approach an employee’s options for each vesting period are separately valued and amortized, which appears to be the preferred method for option grants with graded vesting.

Earnings Per Share [Abstract]
Earnings per Share	Note 6 – 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 13,801,635 weighted average shares outstanding during the first quarter of 2017, and 13,265,371 during the first quarter of 2016. Diluted earnings per share 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 first quarter of 2017, calculations under the treasury stock method resulted in the equivalent of 207,861 shares being added to basic weighted average shares outstanding for purposes of determining diluted earnings per share, while a weighted average of 90,000 stock options were excluded from the calculation because they were underwater and thus anti-dilutive. For the first quarter of 2016 the equivalent of 121,281 shares were added in calculating diluted earnings per share, while 216,100 anti-dilutive stock options were excluded.

Comprehensive Income	Note 7 – 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. Gains or losses on investment securities 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 8 – 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. March 31, 2017 December 31, 2016 Commitments to extend credit $ 577,980 $ 463,923 Standby letters of credit $ 8,482 $ 8,582 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 generally unsecured and 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 March 31, 2017, the Company was also utilizing a letter of credit in the amount of $ 97

Fair Value Disclosures [Abstract]
Fair Value Disclosures and Reporting, the Fair Value Option and Fair Value Measurements	Note 9 – 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 all entities to disclose in their financial statement footnotes the estimated fair values of financial instruments for which it is practicable to estimate fair values. In addition to disclosure requirements, FASB’s standard on investments requires that our debt securities which are classified as available for sale and our equity securities that 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. The 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 realized gains and losses could have a significant effect on fair value estimates but have not been considered in those estimates. Because no active market exists for a significant portion of our financial instruments, fair value disclosures are based on judgments regarding current economic conditions, risk characteristics of various financial instruments and other factors. The estimates are subjective and involve uncertainties and matters of significant judgment, and therefore cannot be determined with precision. Changes in assumptions could significantly alter the fair values presented. The following methods and assumptions were used by the Company to estimate its financial instrument fair values disclosed at March 31, 2017 and December 31, 2016: ⋅ Cash and cash equivalents and fed funds sold : The carrying amount is estimated to be fair value. ⋅ 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 when quoted prices for specific securities are not readily available. ⋅ Loans and leases : For variable-rate loans and leases that re-price frequently with no significant changes in credit risk or interest rate spreads relative to current market pricing, fair values are based on carrying values. Fair values for other loans and leases are estimated by discounting projected cash flows at interest rates being offered at each reporting date for loans and leases with similar terms, to borrowers of comparable creditworthiness. The carrying amount of accrued interest receivable approximates its fair value. ⋅ Loans held for sale : Since loans designated by the Company as available-for-sale are typically sold shortly after making the decision to sell them, realized gains or losses are usually recognized within the same period and fluctuations in fair values are not relevant for reporting purposes. If available-for-sale loans are on our books for an extended period of time, the fair value of those loans is determined using quoted secondary-market prices. ⋅ 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. ⋅ Cash surrender value of life insurance policies : Fair values are based on net cash surrender values at each reporting date. ⋅ Other investments : Certain investments for which no secondary market exists are carried at cost and the carrying amount for those investments typically approximates their estimated fair value, unless an impairment analysis indicates the need for adjustments. ⋅ Deposits : Fair values for non-maturity deposits are equal to the amount payable on demand at the reporting date, which is the carrying amount. Fair values for fixed-rate certificates of deposit are estimated using a cash flow analysis, discounted at interest rates being offered at each reporting date by the Bank for certificates with similar remaining maturities. The carrying amount of accrued interest payable approximates its fair value. ⋅ Short-term borrowings : Current carrying amounts are used as an approximation of fair values for federal funds purchased, overnight advances from the Federal Home Loan Bank (“FHLB”), borrowings under repurchase agreements, and other short-term borrowings maturing within ninety days of the reporting dates. Fair values of other short-term borrowings are estimated by discounting projected cash flows at the Company’s current incremental borrowing rates for similar types of borrowing arrangements. ⋅ Long-term borrowings : Fair values are estimated using projected cash flows discounted at the Company’s current incremental borrowing rates for similar types of borrowing arrangements. ⋅ Subordinated debentures : Fair values are determined based on the current market value for like instruments of a similar maturity and structure. ⋅ Commitments to extend credit and letters of credit : If funded, the carrying amounts for currently unused commitments would provide an equivalent measure of fair values for the newly created financial assets at the funding date. However, because of the high degree of uncertainty with regard to whether or not those commitments will ultimately be funded, fair values for loan commitments and letters of credit in their current undisbursed state cannot reasonably be estimated, and only notional values are disclosed in the table below. 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) March 31, 2017 Estimated Fair Value Quoted Prices in Significant Significant Active Markets for Observable Unobservable Carrying Identical Assets Inputs Inputs Amount (Level 1) (Level 2) (Level 3) Total Financial assets: Cash and cash equivalents $ 92,768 $ 92,768 $ - $ - $ 92,768 Securities available for sale 551,256 1,645 549,611 - 551,256 Loans and leases, net held for investment 1,228,731 - 1,240,991 - 1,240,991 Collateral dependent impaired loans 447 - 447 - 447 Cash surrender value of life insurance policies 44,379 - 44,379 - 44,379 Other investments 8,506 - 8,506 - 8,506 Accrued interest receivable 5,997 - 5,997 - 5,997 Financial liabilities: Deposits: Non-interest-bearing $ 504,247 $ 504,247 $ - $ - $ 504,247 Interest-bearing 1,216,174 - 1,216,510 - 1,216,510 Fed funds purchased and repurchase agreements 9,431 - 9,431 - 9,431 Short-term borrowings - - - - - Subordinated debentures 34,454 - 22,744 - 22,744 Accrued interest payable 137 - 137 - 137 Notional Amount Off-balance-sheet financial instruments: Commitments to extend credit $ 577,980 Standby letters of credit 8,482 December 31, 2016 Estimated Fair Value Quoted Prices in Significant Significant Active Markets for Observable Unobservable Carrying Identical Assets Inputs Inputs Amount (Level 1) (Level 2) (Level 3) Total Financial assets: Cash and cash equivalents $ 120,442 $ 120,442 $ - $ - $ 120,442 Securities available for sale 530,083 1,546 528,537 - 530,083 Loans and leases, net held for investment 1,255,348 - 1,266,447 - 1,266,447 Collateral dependent impaired loans 406 - 406 - 406 Cash surrender value of life insurance policies 43,706 - 43,706 - 43,706 Other investments 8,506 - 8,506 - 8,506 Accrued interest receivable 6,354 - 6,354 - 6,354 Financial liabilities: Deposits: Non-interest-bearing $ 524,552 $ 524,552 $ - $ - $ 524,552 Interest-bearing 1,170,919 - 1,171,188 - 1,171,188 Fed funds purchased and repurchase agreements 8,094 - 8,094 - 8,094 Short-term borrowings 65,000 - 65,000 - 65,000 Subordinated debentures 34,410 - 22,633 - 22,633 Accrued interest payable 188 - 188 - 188 Notional Amount Off-balance-sheet financial instruments: Commitments to extend credit $ 463,923 Standby letters of credit 8,582 For financial asset categories that were actually reported at fair value as of March 31, 2017 and December 31, 2016, 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, and 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.

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 Operation 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. Increases or decreases in 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 10 – 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 tax credits flow through to investors, supplementing any returns that might be derived from an increase in property values. 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. The Company invested in seven LIHTC fund limited partnerships from 2001 through 2007, and in the second quarter of 2016 we committed $ 3 As of March 31, 2017 our total LIHTC investment book balance was $ 6.6 1.5 172,000 237,000

Credit Quality and Nonperforming Assets [Abstract]
Credit Quality and Nonperforming Assets	Note 11 – 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 risk classifications utilized: ⋅ 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 a 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).

OREO consists of real properties acquired by foreclosure or similar means, which the Company is offering or will offer for sale. Nonperforming loans and leases result 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.

The company had no finance receivables modified as TDRs within the previous twelve months that defaulted or were charged off during the three month periods ended March 31, 2017 and 2016 respectively. 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 estimates the amount and timing of expected cash flows, and expected cash receipts in excess of the amount paid for the loan(s) 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 acquisitions of Santa Clara Valley Bank in the fourth quarter of 2014 and Coast Bancorp in the third quarter of 2016 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.

Provision for Loan and Lease Losses [Abstract]
Allowance for Loan and Lease Losses	Note 12 – 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 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 at least quarterly. Pursuant to that 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 $ 1.100 1.048 (dollars in thousands, unaudited) March 31, 2017 Average Unpaid Principal Recorded Related Recorded Interest Income Balance (1) Investment (2) Allowance Investment Recognized (3) With an allowance recorded Real Estate: 1-4 family residential construction $ - $ - $ - $ - $ - Other construction/land 389 234 13 448 3 1-4 Family - closed-end 7,256 5,301 130 7,865 112 Equity lines 4,299 4,214 338 4,392 27 Multi-family residential 568 568 45 582 9 Commercial real estate- owner occupied 1,314 1,234 44 3,244 19 Commercial real estate- non-owner occupied 1,855 1,708 35 1,924 32 Farmland - - - - - Total real estate 15,681 13,259 605 18,455 202 Agricultural 22 22 22 22 - Commercial and industrial 2,671 2,671 572 2,832 22 Consumer loans 1,459 1,459 288 1,635 22 19,833 17,411 1,487 22,944 246 With no related allowance recorded Real estate: 1-4 family residential construction $ - $ - $ - $ - $ - Other construction/land 361 361 - 366 6 1-4 family - closed-end 570 570 - 638 1 Equity lines 426 426 - 500 - Multi-family residential - - - - - Commercial real estate- owner occupied 936 936 - 104 20 Commercial real estate- non-owner occupied - - - 49 - Farmland 38 38 - 49 - Total real estate 2,331 2,331 - 1,706 27 Agricultural - - - - - Commercial and industrial 49 49 - 175 - Consumer loans 116 90 - 283 - 2,496 2,470 - 2,164 27 Total $ 22,329 $ 19,881 $ 1,487 $ 25,108 $ 273 (1) Contractual principal balance due from customer.

(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 to determine a specific loss allowance if they 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 where applicable, 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. Current appraisals were available or in process for 89 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 $ 8.101 There were no material changes to the methodology used to determine our allowance for loan and lease losses during the three months ended March 31, 2017, although in recognition of relatively low loan loss rates in recent periods upward adjustments were made to qualitative factor multipliers. As we add new products and expand our geographic coverage, and as the economic environment changes, we expect to enhance our methodology to keep pace with the size and complexity of the 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 Company’s external auditors, 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.
