Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Summary of Significant Accounting and Reporting Policies	Organization and Summary of Significant Accounting and Reporting Policies The consolidated financial statements include the accounts of United Security Bancshares, and its wholly owned subsidiary United Security Bank (the “Bank”) and two bank subsidiaries, USB Investment Trust (the “REIT”) and United Security Emerging Capital Fund (collectively the “Company” or “USB”). Intercompany accounts and transactions have been eliminated in consolidation. These unaudited financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information on a basis consistent with the accounting policies reflected in the audited financial statements of the Company included in its 2016 Annual Report on Form 10-K. These interim financial statements do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of a normal, recurring nature) considered necessary for a fair presentation have been included. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for any other interim period or for the year as a whole. Recently Issued Accounting Standards : In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606), which creates Topic 606 and supersedes Topic 605, Revenue Recognition. In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606), which postponed the effective date of 2014-09. Multiple ASUs and interpretative guidance have been issued in connection with ASU 2014-09. The core principle of Topic 606 is that an entity recognizes 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. In general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The standard is effective for public entities for interim and annual periods beginning after December 15, 2017; early adoption is not permitted. For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company has begun their process to implement this new standard by reviewing all revenue sources to determine the sources that are in scope for this guidance. As a bank, key revenue sources, such as interest income have been identified as out of scope of this new guidance. The Company has not yet determined the financial statement impact this guidance will have. In January 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-01 Financial Instruments-Overall: Recognition and Measurements of Financial Assets and Financial Liabilities. This ASU requires equity investments to be measured at fair value, with changes in fair value recognized in net income. The amendment also simplifies the impairment assessment of equity investments for which fair value is not readily determinable by requiring an entity to perform a qualitative assessment to identify impairment. The ASU is effective for fiscal years beginning after December 15, 2017, and interim periods therein. The Company expects this ASU to impact its consolidated income and other comprehensive income disclosures for the fair value of its mutual fund investment and junior subordinated debenture. In February 2016, FASB issued ASU 2016-02, Leases (Topic 842). The FASB is issuing this Update to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. To meet that objective, the FASB is amending the FASB Accounting Standards Codification® and creating Topic 842, Leases. This Update, along with IFRS 16, Leases, are the results of the FASB’s and the International Accounting Standards Board’s (IASB’s) efforts to meet that objective and improve financial reporting. This ASU will be effective for public business entities for annual periods beginning after December 15, 2018 (i.e., calendar periods beginning on January 1, 2019), and interim periods therein. Although an estimate of the impact of the new leasing standard has not yet been determined, the Company expects a significant new lease asset and related lease liability on the balance sheet due to the number of leased branches and standalone ATM sites the Bank currently has that are accounted for under current operating lease guidance. In June 2016, FASB issued ASU 2016-13, Financial Instruments- Credit Losses (Topic 326). The FASB is issuing this Update to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The Update requires enhanced disclosures and judgments in estimating credit losses and also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. This amendment is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company has established a project team for the implementation of this new standard. The team has started by working with a vendor to put a new Allowance for Loan Loss software in place and is collecting additional historical data to estimate the impact of this standard. An estimate of the impact of this standard has not yet been determined, however, the impact is expected to be significant. As of January 1, 2017, the Company adopted the Financial Accounting Standards Board's (FASB) Accounting Standard Update ("ASU") No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09, seeks to simplify several aspects of the accounting for employee share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. As required by ASU 2016-09, all adjustments are reflected as of the beginning of the fiscal year, January 1, 2016. By applying this ASU, the Company no longer adjusts common stock for the tax impact of shares released, instead the tax impact is recognized as tax expense in the period the shares are released. This simplifies the tracking of the excess tax benefits and deficiencies, but could cause volatility in tax expense for the periods presented. The statement of cash flows has been adjusted to reflect the provisions of this ASU. The application of this ASU did not have a material impact on the financial statements. In January 2017, FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350). The FASB is issuing this Update to eliminate the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. This ASU will be effective for public business entities for annual periods beginning after December 15, 2019 (i.e. calendar periods beginning on January 1, 2020, and interim periods therein. The Company does not expect any impact on the Company's consolidated financial statements resulting from the adoption of this update. In March 2017, FASB issued ASU 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The provisions of the update require premiums recognized upon the purchase of callable debt securities to be amortized to the earliest call date in order to avoid losses recognized upon call. For public business entities that are SEC filers the amendments of the update will become effective in fiscal years beginning after December 15, 2018. The Company does not expect the requirements of this update to have a material impact on the Company’s financial position, results of operations or cash flows.

Actual maturities may differ from contractual maturities because issuers have the right to call or prepay obligations with or without call or prepayment penalties. Contractual maturities on collateralized mortgage obligations cannot be anticipated due to allowed paydowns. Mutual funds are included in the "due in one year or less" category below.

There were no other-than-temporary impairment losses for the three and six month periods ended June 30, 2017 and June 30, 2016 . At June 30, 2017 , available-for-sale securities with an amortized cost of approximately $18,005,228 (fair value of $18,196,687 ) were pledged as collateral for FHLB borrowings and public funds balances. The Company had no held-to-maturity or trading securities at June 30, 2017 or December 31, 2016 . Management periodically evaluates each available-for-sale investment security in an unrealized loss position to determine if the impairment is temporary or other-than-temporary.

The Company evaluates investment securities for other-than-temporary impairment (OTTI) at least quarterly, and more frequently when economic or market conditions warrant such an evaluation. The investment securities portfolio is evaluated for OTTI by segregating the portfolio into two general segments and applying the appropriate OTTI model. Investment securities classified as available-for-sale or held-to-maturity are generally evaluated for OTTI under ASC Topic 320, Investments – Debt and Equity Instruments . Certain purchased beneficial interests, including non-agency mortgage-backed securities, asset-backed securities, and collateralized debt obligations, are evaluated under ASC Topic 325-40, Beneficial Interest in Securitized Financial Assets. In the first segment, the Company considers many factors in determining OTTI, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the Company has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to the Company at the time of the evaluation. The second segment of the portfolio uses the OTTI guidance that is specific to purchased beneficial interests including private label mortgage-backed securities. Under this model, the Company compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows. Additionally, other-than-temporary-impairment occurs when the Company intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss. If the Company intends to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the other-than-temporary-impairment shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis less any current-period loss, the other-than-temporary-impairment shall be separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total other-than-temporary-impairment related to the credit loss is recognized in earnings, and is determined based on the difference between the present value of cash flows expected to be collected and the current amortized cost of the security. The amount of the total other-than-temporary-impairment related to other factors shall be recognized in other comprehensive (loss) income, net of applicable taxes. The previous amortized cost basis less the other-than-temporary-impairment recognized in earnings shall become the new amortized cost basis of the investment. At June 30, 2017 , the decline in fair value of the impaired mutual fund, the two U.S. government agency securities, and the twelve U.S. government sponsored entities and agencies collateralized by mortgage obligations securities is attributable to changes in interest rates, and not credit quality. Because the Company does not have the intent to sell these impaired securities, and it is not more likely than not that it will be required to sell these securities before its anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2017 .

Receivables [Abstract]
Loans	Loans Loans are comprised of the following: (in 000's) June 30, 2017 December 31, 2016 Commercial and Business Loans $ 51,078 $ 47,464 Government Program Loans 1,393 1,541 Total Commercial and Industrial 52,471 49,005 Real Estate – Mortgage: Commercial Real Estate 202,364 200,213 Residential Mortgages 79,319 87,388 Home Improvement and Home Equity loans 572 599 Total Real Estate Mortgage 282,255 288,200 Real Estate Construction and Development 124,749 130,687 Agricultural 58,432 56,918 Installment 49,333 44,949 Total Loans $ 567,240 $ 569,759 The Company's loans are predominantly in the San Joaquin Valley and the greater Oakhurst/East Madera County area, as well as the Campbell area of Santa Clara County. Although the Company does participate in loans with other financial institutions, they are primarily in the state of California. Commercial and industrial loans represent 9.3% of total loans at June 30, 2017 and are generally made to support the ongoing operations of small-to-medium sized commercial businesses. Commercial and industrial loans have a high degree of industry diversification and provide working capital, financing for the purchase of manufacturing plants and equipment, or funding for growth and general expansion of businesses. A substantial portion of commercial and industrial loans are secured by accounts receivable, inventory, leases, or other collateral including real estate. The remainder are unsecured; however, extensions of credit are predicated upon the financial capacity of the borrower. Repayment of commercial loans is generally from the cash flow of the borrower. Real estate mortgage loans, representing 49.8% of total loans at June 30, 2017 , are secured by trust deeds on primarily commercial property, but are also secured by trust deeds on single family residences. Repayment of real estate mortgage loans generally comes from the cash flow of the borrower. • Commercial real estate mortgage loans comprise the largest segment of this loan category and are available on all types of income producing and commercial properties, including: office buildings, shopping centers; apartments and motels; owner occupied buildings; manufacturing facilities and more. Commercial real estate mortgage loans can also be used to refinance existing debt. Although real estate associated with the business is the primary collateral for commercial real estate mortgage loans, the underlying real estate is not the source of repayment. Commercial real estate loans are made under the premise that the loan will be repaid from the borrower's business operations, rental income associated with the real property, or personal assets. • Residential mortgage loans are provided to individuals to finance or refinance single-family residences. Residential mortgages are not a primary business line offered by the Company, and a majority are conventional mortgages that were purchased as a pool. Most residential mortgages originated by the Company are of a shorter term than conventional mortgages, with maturities ranging from 3 to 15 years on average. • Home Improvement and Home Equity loans comprise a relatively small portion of total real estate mortgage loans, and are offered to borrowers for the purpose of home improvements, although the proceeds may be used for other purposes. Home equity loans are generally secured by junior trust deeds, but may be secured by 1 st trust deeds. Real estate construction and development loans, representing 22.0% of total loans at June 30, 2017 , consist of loans for residential and commercial construction projects, as well as land acquisition and development, or land held for future development. Loans in this category are secured by real estate including improved and unimproved land, as well as single-family residential, multi-family residential, and commercial properties in various stages of completion. All real estate loans have established equity requirements. Repayment on construction loans generally comes from long-term mortgages with other lending institutions obtained at completion of the project. Agricultural loans represent 10.3% of total loans at June 30, 2017 and are generally secured by land, equipment, inventory and receivables. Repayment is from the cash flow of the borrower. Installment loans represent 8.7% of total loans at June 30, 2017 and generally consist of student loans, loans to individuals for household, family and other personal expenditures such as credit cards, automobiles or other consumer items. Included in installment loans are $42,983,000 in student loans made to medical and pharmacy school students. Repayment on student loans is deferred until 6 months after graduation. Accrued interest on loans that have not entered repayment status totaled $3,131,000 at June 30, 2017 . In the normal course of business, the Company is party to financial instruments with off-balance sheet risk to meet the financing needs of its customers. At June 30, 2017 and December 31, 2016 , these financial instruments include commitments to extend credit of $102,616,000 and $120,485,000 , respectively, and standby letters of credit of $1,630,000 and $1,201,000 , respectively. These instruments involve elements of credit risk in excess of the amount recognized on the consolidated balance sheet. The contract amounts of these instruments reflect the extent of the involvement the Company has in off-balance sheet financial instruments. The Company’s exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amounts of those instruments. The Company uses the same credit policies as it does for on-balance sheet instruments. Commitments to extend credit are agreements to lend to a customer, as long as there is no violation of any condition established in the contract. A majority of these commitments are at floating interest rates based on the Prime rate. Commitments generally have fixed expiration dates. The Company evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management's credit evaluation. Collateral held varies but includes accounts receivable, inventory, leases, property, plant and equipment, residential real estate and income-producing properties. Standby letters of credit are generally unsecured and are issued by the Company to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Past Due Loans The Company monitors delinquency and potential problem loans on an ongoing basis through weekly reports to the Loan Committee and monthly reports to the Board of Directors. The following is a summary of delinquent loans at June 30, 2017 (in 000's): June 30, 2017 Loans 30-60 Days Past Due Loans 61-89 Days Past Due Loans 90 or More Days Past Due Total Past Due Loans Current Loans Total Loans Accruing Loans 90 or More Days Past Due Commercial and Business Loans $ 422 $ 22 $ 87 $ 531 $ 50,547 $ 51,078 $ 87 Government Program Loans — — 280 280 1,113 1,393 — Total Commercial and Industrial 422 22 367 811 51,660 52,471 87 Commercial Real Estate Loans — — — — 202,364 202,364 — Residential Mortgages — — — — 79,319 79,319 — Home Improvement and Home Equity Loans — — — — 572 572 — Total Real Estate Mortgage — — — — 282,255 282,255 — Real Estate Construction and Development Loans — — — — 124,749 124,749 — Agricultural Loans — — — — 58,432 58,432 — Consumer Loans — — — — 49,146 49,146 — Overdraft Protection Lines — — — — 46 46 — Overdrafts — — — — 141 141 — Total Installment — — — — 49,333 49,333 — Total Loans $ 422 $ 22 $ 367 $ 811 $ 566,429 $ 567,240 $ 87 The following is a summary of delinquent loans at December 31, 2016 (in 000's): December 31, 2016 Loans 30-60 Days Past Due Loans 61-89 Days Past Due Loans 90 or More Days Past Due Total Past Due Loans Current Loans Total Loans Accruing Loans 90 or More Days Past Due Commercial and Business Loans $ — $ 432 $ — $ 432 $ 47,032 $ 47,464 $ — Government Program Loans — — 290 290 1,251 1,541 — Total Commercial and Industrial — 432 290 722 48,283 49,005 — Commercial Real Estate Loans — — — — 200,213 200,213 — Residential Mortgages — — — — 87,388 87,388 — Home Improvement and Home Equity Loans — — — — 599 599 — Total Real Estate Mortgage — — — — 288,200 288,200 — Real Estate Construction and Development Loans 166 — 1,250 1,416 129,271 130,687 1,250 Agricultural Loans — — — — 56,918 56,918 — Consumer Loans — — 965 965 43,785 44,750 — Overdraft Protection Lines — — — — 48 48 — Overdrafts — — — — 151 151 — Total Installment — — 965 965 43,984 44,949 — Total Loans $ 166 $ 432 $ 2,505 $ 3,103 $ 566,656 $ 569,759 $ 1,250 Nonaccrual Loans Commercial, construction and commercial real estate loans are placed on nonaccrual status under the following circumstances: - When there is doubt regarding the full repayment of interest and principal. - When principal and/or interest on the loan has been in default for a period of 90 -days or more, unless the asset is both well secured and in the process of collection that will result in repayment in the near future. - When the loan is identified as having loss elements and/or is risk rated "8" Doubtful. Other circumstances which jeopardize the ultimate collectability of the loan including certain troubled debt restructurings, identified loan impairment, and certain loans to facilitate the sale of OREO. Loans meeting any of the preceding criteria are placed on nonaccrual status and the accrual of interest for financial statement purposes is discontinued. Previously accrued but unpaid interest is reversed and charged against interest income. All other loans where principal or interest is due and unpaid for 90 days or more are placed on nonaccrual and the accrual of interest for financial statement purposes is discontinued. Previously accrued but unpaid interest is reversed and charged against interest income. When a loan is placed on nonaccrual status and subsequent payments of interest (and principal) are received, the interest received may be accounted for in two separate ways. Cost recovery method : If the loan is in doubt as to full collection, the interest received in subsequent payments is diverted from interest income to a valuation reserve and treated as a reduction of principal for financial reporting purposes. Cash basis : This method is only used if the recorded investment or total contractual amount is expected to be fully collectible, under which circumstances the subsequent payments of interest are credited to interest income as received. Loans on non-accrual status are usually not returned to accrual status unless all delinquent principal and/or interest has been brought current, there is no identified element of loss, and current and continued satisfactory performance is expected (loss of the contractual amount not the carrying amount of the loan). Return to accrual is generally demonstrated through the timely receipt of at least six monthly payments on a loan with monthly amortization. Nonaccrual loans totaled $5,508,000 and $7,264,000 at June 30, 2017 and December 31, 2016 , respectively. There were no remaining undisbursed commitments to extend credit on nonaccrual loans at June 30, 2017 or December 31, 2016 . The following is a summary of nonaccrual loan balances at June 30, 2017 and December 31, 2016 (in 000's). June 30, 2017 December 31, 2016 Commercial and Business Loans $ 281 $ 275 Government Program Loans 280 290 Total Commercial and Industrial 561 565 Commercial Real Estate Loans 473 1,126 Residential Mortgages — — Home Improvement and Home Equity Loans — — Total Real Estate Mortgage 473 1,126 Real Estate Construction and Development Loans 4,474 4,608 Agricultural Loans — — Consumer Loans — 965 Overdraft Protection Lines — — Overdrafts — — Total Installment — 965 Total Loans $ 5,508 $ 7,264 Impaired Loans 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, including principal and interest, according to the contractual terms of the loan agreement. The Company applies its normal loan review procedures in making judgments regarding probable losses and loan impairment. The Company evaluates for impairment those loans on nonaccrual status, graded doubtful, graded substandard or those that are troubled debt restructures. The primary basis for inclusion in impaired status under generally accepted accounting pronouncements is that it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement. A loan is not considered impaired if there is merely an insignificant delay or shortfall in the amounts of payments and the Company expects to collect all amounts due, including interest accrued, at the contractual interest rate for the period of the delay. Review for impairment does not include large groups of smaller balance homogeneous loans that are collectively evaluated to estimate the allowance for loan losses. The Company’s present allowance for loan losses methodology, including migration analysis, captures required reserves for these loans in the formula allowance. For loans determined to be impaired, the Company evaluates impairment based upon either the fair value of underlying collateral, discounted cash flows of expected payments, or observable market price. - For loans secured by collateral including real estate and equipment, the fair value of the collateral less selling costs will determine the carrying value of the loan. The difference between the recorded investment in the loan and the fair value, less selling costs, determines the amount of impairment. The Company uses the measurement method based on fair value of collateral when the loan is collateral dependent and foreclosure is probable. For loans that are not considered collateral dependent, a discounted cash flow methodology is used. - The discounted cash flow method of measuring the impairment of a loan is used for impaired loans that are not considered to be collateral dependent. Under this method, the Company assesses both the amount and timing of cash flows expected from impaired loans. The estimated cash flows are discounted using the loan's effective interest rate. The difference between the amount of the loan on the Bank's books and the discounted cash flow amounts determines the amount of impairment to be provided. This method is used for most of the Company’s troubled debt restructurings or other impaired loans where some payment stream is being collected. - The observable market price method of measuring the impairment of a loan is only used by the Company when the sale of loans or a loan is in process. The method for recognizing interest income on impaired loans is dependent on whether the loan is on nonaccrual status or is a troubled debt restructure. For income recognition, the existing nonaccrual and troubled debt restructuring policies are applied to impaired loans. Generally, except for certain troubled debt restructurings which are performing under the restructure agreement, the Company does not recognize interest income received on impaired loans, but reduces the carrying amount of the loan for financial reporting purposes. Loans other than certain homogeneous loan portfolios are reviewed on a quarterly basis for impairment. Impaired loans are written down to estimated realizable values by the establishment of specific reserves for loan utilizing the discounted cash flow method, or charge-offs for collateral-based impaired loans, or those using observable market pricing.

(2) Information is based on the twelve month period ended December 31, 2016 . In most cases, the Company uses the cash basis method of income recognition for impaired loans. In the case of certain troubled debt restructurings for which the loan is performing under the current contractual terms for a reasonable period of time, income is recognized under the accrual method. The average recorded investment in impaired loans for the quarters ended June 30, 2017 and 2016 was $16,881,000 and $23,163,000 , respectively. Interest income recognized on impaired loans for the quarters ended June 30, 2017 and 2016 was approximately $323,000 and $317,000 , respectively. For impaired nonaccrual loans, interest income recognized under a cash-basis method of accounting was approximately $111,000 and $87,000 for the quarters ended June 30, 2017 and 2016 , respectively. The average recorded investment in impaired loans for the six months ended June 30, 2017 and 2016 was $16,468,000 and $23,336,000 , respectively. Interest income recognized on impaired loans for the six months ended June 30, 2017 and 2016 was approximately $546,000 and $680,000 , respectively. For impaired nonaccrual loans, interest income recognized under a cash-basis method of accounting was approximately $190,000 and $236,000 for the six months ended June 30, 2017 and 2016 , respectively. Troubled Debt Restructurings In certain circumstances, when the Company grants a concession to a borrower as part of a loan restructuring, the restructuring is accounted for as a troubled debt restructuring (TDR). TDRs are reported as a component of impaired loans. A TDR is a type of restructuring in which the Company, for economic or legal reasons related to the borrower's financial difficulties, grants a concession (either imposed by court order, law, or agreement between the borrower and the Bank) to the borrower that it would not otherwise consider. Although the restructuring may take different forms, the Company's objective is to maximize recovery of its investment by granting relief to the borrower. A TDR may include, but is not limited to, one or more of the following: - A transfer from the borrower to the Company of receivables from third parties, real estate, other assets, or an equity interest in the borrower is granted to fully or partially satisfy the loan. - A modification of terms of a debt such as one or a combination of: ◦ The reduction (absolute or contingent) of the stated interest rate. ◦ The extension of the maturity date or dates at a stated interest rate lower than the current market rate for new debt with similar risk. ◦ The reduction (absolute or contingent) of the face amount or maturity amount of debt as stated in the instrument or agreement. ◦ The reduction (absolute or contingent) of accrued interest. For a restructured loan to return to accrual status there needs to be, among other factors, at least 6 months successful payment history. In addition, the Company performs a financial analysis of the credit to determine whether the borrower has the ability to continue to meet payments over the remaining life of the loan. This includes, but is not limited to, a review of financial statements and cash flow analysis of the borrower. Only after determination that the borrower has the ability to perform under the terms of the loans, will the restructured credit be considered for accrual status. Although the Company does not have a policy which specifically addresses when a loan may be removed from TDR classification, as a matter of practice, loans classified as TDRs generally remain classified as such until the loan either reaches maturity or its outstanding balance is paid off. The following tables illustrates TDR activity for the periods indicated: Three Months Ended June 30, 2017 ($ in 000's) Number of Pre- Post- Number of Contracts which Defaulted During Period Recorded Investment on Defaulted TDRs Troubled Debt Restructurings Commercial and Business Loans — $ — $ — — $ — Government Program Loans 1 178 178 — — Commercial Real Estate Term Loans — — — — — Single Family Residential Loans 1 238 238 — — Home Improvement and Home Equity Loans — — — — — Real Estate Construction and Development Loans — — — — — Agricultural Loans — — — — — Consumer Loans — — — — — Overdraft Protection Lines — — — — — Total Loans 2 $ 416 $ 416 — $ — Six Months Ended June 30, 2017 ($ in 000's) Number of Pre- Post- Number of Contracts which Defaulted During Period Recorded Investment on Defaulted TDRs Troubled Debt Restructurings Commercial and Business Loans 1 $ 69 $ 69 — $ — Government Program Loans 1 178 178 — — Commercial Real Estate Term Loans — — — — — Single Family Residential Loans 1 238 238 — — Home Improvement and Home Equity Loans — — — — — Real Estate Construction and Development Loans 1 790 790 — — Agricultural Loans 1 850 850 — — Consumer Loans — — — — — Overdraft Protection Lines — — — — — Total Loans 5 $ 2,125 $ 2,125 — $ — Three Months Ended June 30, 2016 ($ in 000's) Number of Pre- Post- Number of Contracts which Defaulted During Period Recorded Investment on Defaulted TDRs Troubled Debt Restructurings Commercial and Business Loans 1 $ 395 $ 227 — $ — Government Program Loans — — — — — Commercial Real Estate Term Loans — — — — — Single Family Residential Loans — — — — — Home Improvement and Home Equity Loans — — — — — Real Estate Construction and Development Loans — — — — — Agricultural Loans — — — — — Consumer Loans — — — — — Overdraft Protection Lines — — — — — Total Loans 1 $ 395 $ 227 — $ — Six Months Ended June 30, 2016 ($ in 000's) Number of Pre- Post- Number of Contracts which Defaulted During Period Recorded Investment on Defaulted TDRs Troubled Debt Restructurings Commercial and Business Loans 4 $ 1,021 $ 749 — $ — Government Program Loans 1 100 100 — — Commercial Real Estate Term Loans — — — — — Single Family Residential Loans — — — — — Home Improvement and Home Equity Loans — — — — — Real Estate Construction and Development Loans — — — — — Agricultural Loans — — — — — Consumer Loans — — — — — Overdraft Protection Lines — — — — — Total Loans 5 $ 1,121 $ 849 — $ — The Company makes various types of concessions when structuring TDRs including rate reductions, payment extensions, and forbearance.

The system rates the strength of the borrower and the facility or transaction, and is designed to provide a program for risk management and early detection of problems. For each new credit approval, credit extension, renewal, or modification of existing credit facilities, the Company assigns risk ratings utilizing the rating scale identified in this policy. In addition, on an on-going basis, loans and credit facilities are reviewed for internal and external influences impacting the credit facility that would warrant a change in the risk rating. Each loan credit facility is to be given a risk rating that takes into account factors that materially affect credit quality. When assigning risk ratings, the Company evaluates two risk rating approaches, a facility rating and a borrower rating as follows: Facility Rating: The facility rating is determined by the analysis of positive and negative factors that may indicate that the quality of a particular loan or credit arrangement requires that it be rated differently from the risk rating assigned to the borrower. The Company assesses the risk impact of these factors: Collateral - The rating may be affected by the type and quality of the collateral, the degree of coverage, the economic life of the collateral, liquidation value and the Company's ability to dispose of the collateral. Guarantees - The value of third party support arrangements varies widely. Unconditional guaranties from persons with demonstrable ability to perform are more substantial than that of closely related persons to the borrower who offer only modest support. Unusual Terms - Credit may be extended on terms that subject the Company to a higher level of risk than indicated in the rating of the borrower. Borrower Rating: The borrower rating is a measure of loss possibility based on the historical, current and anticipated financial characteristics of the borrower in the current risk environment. To determine the rating, the Company considers at least the following factors: - Quality of management - Liquidity - Leverage/capitalization - Profit margins/earnings trend - Adequacy of financial records - Alternative funding sources - Geographic risk - Industry risk - Cash flow risk - Accounting practices - Asset protection - Extraordinary risks The Company assigns risk ratings to loans other than consumer loans and other homogeneous loan pools based on the following scale. The risk ratings are used when determining borrower ratings as well as facility ratings. When the borrower rating and the facility ratings differ, the lowest rating applied is: - Grades 1 and 2 – These grades include loans which are given to high quality borrowers with high credit quality and sound financial strength. Key financial ratios are generally above industry averages and the borrower’s strong earnings history or net worth. These may be secured by deposit accounts or high-grade investment securities. - Grade 3 – This grade includes loans to borrowers with solid credit quality with minimal risk. The borrower’s balance sheet and financial ratios are generally in line with industry averages, and the borrower has historically demonstrated the ability to manage economic adversity. Real estate and asset-based loans assigned this risk rating must have characteristics, which place them well above the minimum underwriting requirements for those departments. Asset-based borrowers assigned this rating must exhibit extremely favorable leverage and cash flow characteristics, and consistently demonstrate a high level of unused borrowing capacity. - Grades 4 and 5 – These include “pass” grade loans to borrowers of acceptable credit quality and risk. The borrower’s balance sheet and financial ratios may be below industry averages, but above the lowest industry quartile. Leverage is above and liquidity is below industry averages. Inadequacies evident in financial performance and/or management sufficiency are offset by readily available features of support, such as adequate collateral, or good guarantors having the liquid assets and/or cash flow capacity to repay the debt. The borrower may have recognized a loss over three or four years, however recent earnings trends, while perhaps somewhat cyclical, are improving and cash flows are adequate to cover debt service and fixed obligations. Real estate and asset-borrowers fully comply with all underwriting standards and are performing according to projections would be assigned this rating. These also include grade 5 loans which are “leveraged” or on management’s “watch list.” While still considered pass loans (loans given a grade 5), the borrower’s financial condition, cash flow or operations evidence more than average risk and short term weaknesses, these loans warrant a higher than average level of monitoring, supervision and attention from the Company, but do not reflect credit weakness trends that weaken or inadequately protect the Company’s credit position. Loans with a grade rating of 5 are not normally acceptable as new credits unless they are adequately secured or carry substantial endorser/guarantors. - Grade 6 – This grade includes “special mention” loans which are loans that are currently protected but are potentially weak. This generally is an interim grade classification and should usually be upgraded to an Acceptable rating or downgraded to Substandard within a reasonable time period. Weaknes

Equity [Abstract]
Dividends on Common Stock	Dividends on Common Stock On March 28, 2017 , the Company’s Board of Directors declared a one-percent ( 1% ) stock dividend on the Company’s outstanding common stock. Based upon the number of outstanding common shares on the record date of April 7, 2017 , 167,082 additional shares were issued to shareholders on April 17, 2017. Because the stock dividend was considered a “small stock dividend,” approximately $1,219,759 was transferred from retained earnings to common stock based upon the $7.38 closing price of the Company’s common stock on the declaration date of March 28, 2017 . There were no fractional shares paid. Except for earnings-per-share calculations, shares issued for the stock dividend have been treated prospectively for financial reporting purposes. For purposes of earnings per share calculations, the Company’s weighted average shares outstanding and potentially dilutive shares used in the computation of earnings per share have been restated after giving retroactive effect to a 1% stock dividend to shareholders for all periods presented. On April 25, 2017, the Company’s Board of Directors declared a cash dividend of $0.05 per share on the Company's common stock. The dividend was payable on May 17, 2017, to shareholders of record as of May 8, 2017. Approximately $846,000 was transfered from retained earnings to cash to allow for distribution of the dividend to shareholders. The Board of Directors also authorized the repurchase of up to $3 million of the outstanding common stock of the Company. The timing of the purchases will depend on certain factors, including but not limited to, market conditions and prices, available funds, and alternative uses of capital. The stock repurchase program may be carried out through open-market purchases, block trades, or negotiated private transactions. On June 27, 2017, the Company’s Board of Directors declared a cash dividend of $0.05 per share on the Company's common stock. The dividend is payable on July 21, 2017, to shareholders of record as of July 7, 2017. Approximately $844,000 were transfered from retained earnings to cash to allow for distribution of the dividend to shareholders.

Income Tax Disclosure [Abstract]
Taxes on Income	Taxes on Income The Company periodically reviews its tax positions under the accounting standards related to uncertainty in income taxes, which defines the criteria that an individual tax position would have to meet for some or all of the income tax benefit to be recognized in a taxable entity’s financial statements. Under the guidelines, an entity should recognize the financial statement benefit of a tax position if it determines that it is more likely than not that the position will be sustained on examination. The term “more likely than not” means a likelihood of more than 50 percent . In assessing whether the more-likely-than-not criterion is met, the entity should assume that the tax position will be reviewed by the applicable taxing authority and all available information is known to the taxing authority. The Company periodically evaluates its deferred tax assets to determine whether a valuation allowance is required based upon a determination that some or all of the deferred assets may not be ultimately realized. At June 30, 2017 and December 31, 2016 , the Company had no recorded valuation allowance. The Company and its subsidiary file income tax returns in the U.S federal jurisdiction, and several states within the U.S. There are no filings in foreign jurisdictions. During 2014, the Company began the process to amend its California state tax returns for the years 2009 through 2012 to file a combined report on a unitary basis with the Company and USB Investment Trust. The amended returns for 2009, 2010, and 2011 were filed in 2014, 2015, and 2016 respectively. The amended return for 2012 was filed during 2016. During the third quarter of 2016, the IRS notified the Company it would be conducting an examination of the Company's 2014 federal return. As of June 30, 2017 , the Company is unaware of any change in tax positions as a result of the IRS examination. The Company's policy is to recognize any interest or penalties related to uncertain tax positions in income tax expense. Interest and penalties recognized during the periods ended June 30, 2017 and 2016 were insignificant.

Debt Disclosure [Abstract]
Junior Subordinated Debt/Trust Preferred Securities	Junior Subordinated Debt/Trust Preferred Securities Effective September 30, 2009 and beginning with the quarterly interest payment due October 1, 2009, the Company elected to defer interest payments on the Company's $15.0 million of junior subordinated debentures relating to its trust preferred securities. The terms of the debentures and trust indentures allow for the Company to defer interest payments for up to 20 consecutive quarters without default or penalty. During the period that the interest deferrals were elected, the Company continued to record interest expense associated with the debentures. As of June 30, 2014, the Company ended the extension period, paid all accrued and unpaid interest, and is currently making quarterly interest payments. The Company may redeem the junior subordinated debentures at anytime at par. During August 2015, the Bank purchased $3.0 million of the Company's junior subordinated debentures related to the Company's trust preferred securities at a fair value discount of 40% . Subsequently, in September 2015, the Company purchased those shares from the Bank and canceled $3.0 million in par value of the junior subordinated debentures, realizing a $78,000 gain on redemption. The contractual principal balance of the Company's debentures relating to its trust preferred securities is $12.0 million as of June 30, 2017 . The fair value guidance generally permits the measurement of selected eligible financial instruments at fair value at specified election dates. Effective January 1, 2008, the Company elected the fair value option for its junior subordinated debt issued under USB Capital Trust II. The Company believes the election of fair value accounting for the junior subordinated debentures better reflects the true economic value of the debt instrument on the balance sheet. The rate paid on the junior subordinated debt issued under USB Capital Trust II is 3-month LIBOR plus 129 basis points, and is adjusted quarterly. At June 30, 2017 the Company performed a fair value measurement analysis on its junior subordinated debt using a cash flow model approach to determine the present value of those cash flows. The cash flow model utilizes the forward 3-month LIBOR curve to estimate future quarterly interest payments due over the thirty -year life of the debt instrument. These cash flows were discounted at a rate which incorporates a current market rate for similar-term debt instruments, adjusted for additional credit and liquidity risks associated with the junior subordinated debt. We believe the 5.86% discount rate used represents what a market participant would consider under the circumstances based on current market assumptions. At June 30, 2017 , the total cumulative gain recorded on the debt is $3,096,000 . The fair value calculation performed at June 30, 2017 resulted in a pretax loss adjustment of $601,000 ( $354,000 , net of tax) for the six months ended June 30, 2017 , compared to a pretax gain adjustment of $471,000 ( $277,000 , net of tax) for the six months ended June 30, 2016 . Fair value gains and losses are reflected as a component of noninterest income on the consolidated statements of income. The fair value calculation performed at June 30, 2017 resulted in a pretax loss adjustment of $264,000 ( $126,000 , net of tax) for the three months ended June 30, 2017 , compared to a pretax gain adjustment of $113,000 ( $66,000 , net of tax) for the three months ended June 30, 2016 . Fair value gains and losses are reflected as a component of noninterest income on the consolidated statements of income.

Fair Value Disclosures [Abstract]
Fair Value Measurements and Disclosure	Fair Value Measurements and Disclosure The following summary disclosures are made in accordance with the guidance provided by ASC Topic 825, Fair Value Measurements and Disclosures (formerly Statement of Financial Accounting Standards No. 107, Disclosures about Fair Value of Financial Instruments ), which requires the disclosure of fair value information about both on- and off-balance sheet financial instruments where it is practicable to estimate that value. Generally accepted accounting guidance clarifies the definition of fair value, describes methods used to appropriately measure fair value in accordance with generally accepted accounting principles and expands fair value disclosure requirements. This guidance applies whenever other accounting pronouncements require or permit fair value measurements. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels (Level 1, Level 2, and Level 3). Level 1 inputs are unadjusted quoted prices in active markets (as defined) for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability, and reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). The table below is a summary of fair value estimates for financial instruments and the level of the fair value hierarchy within which the fair value measurements are categorized at the periods indicated: June 30, 2017 (in 000's) Carrying Amount Estimated Fair Value Quoted Prices In Active Markets for Identical Assets Level 1 Significant Other Observable Inputs Level 2 Significant Unobservable Inputs Level 3 Financial Assets: Cash and cash equivalents $ 109,508 $ 109,508 $ 109,508 $ — $ — Interest-bearing deposits 652 652 — 652 — Investment securities 53,461 53,461 3,780 49,681 — Loans 559,156 549,386 — — 549,386 Accrued interest receivable 5,086 5,086 — 5,086 — Financial Liabilities: Deposits: Noninterest-bearing 287,003 287,003 287,003 — — NOW and money market 230,981 230,981 230,981 — — Savings 80,539 80,539 80,539 — — Time deposits 67,788 67,433 — — 67,433 Total deposits 666,311 665,956 598,523 67,433 Junior subordinated debt 9,441 9,441 — — 9,441 Accrued interest payable 33 33 — 33 — December 31, 2016 (in 000's) Carrying Amount Estimated Fair Value Quoted Prices In Active Markets for Identical Assets Level 1 Significant Other Observable Inputs Level 2 Significant Unobservable Inputs Level 3 Financial Assets: Cash and cash equivalents $ 113,032 $ 113,032 $ 113,032 $ — $ — Interest-bearing deposits 650 650 — 650 — Investment securities 57,491 57,491 3,716 53,775 — Loans 561,932 557,914 — — 557,914 Accrued interest receivable 3,895 3,895 — 3,895 — Financial Liabilities: Deposits: Noninterest-bearing 262,697 262,697 262,697 — — NOW and money market 235,873 235,873 235,873 — — Savings 75,068 75,068 75,068 — — Time deposits 102,991 102,743 — — 102,743 Total deposits 676,629 676,381 573,638 — 102,743 Junior subordinated debt 8,832 8,832 — — 8,832 Accrued interest payable 76 76 — 76 — The Company performs fair value measurements on certain assets and liabilities as the result of the application of current accounting guidelines. Some fair value measurements, such as available-for-sale securities (AFS) and junior subordinated debt are performed on a recurring basis, while others, such as impairment of loans, other real estate owned, goodwill and other intangibles, are performed on a nonrecurring basis. The Company’s Level 1 financial assets consist of money market funds and highly liquid mutual funds for which fair values are based on quoted market prices. The Company’s Level 2 financial assets include highly liquid debt instruments of U.S. government agencies, collateralized mortgage obligations, and debt obligations of states and political subdivisions, whose fair values are obtained from readily-available pricing sources for the identical or similar underlying security that may, or may not, be actively traded. The Company’s Level 3 financial assets include certain instruments where the assumptions may be made by us or third parties about assumptions that market participants would use in pricing the asset or liability. From time to time, the Company recognizes transfers between Level 1, 2, and 3 when a change in circumstances warrants a transfer. There were no transfers in or out of Level 1 and Level 2 fair value measurements during the three or six month periods ended June 30, 2017 . The following methods and assumptions were used in estimating the fair values of financial instruments: Cash and Cash Equivalents - The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents approximate their estimated fair values. Interest-bearing Deposits – Interest bearing deposits in other banks consist of fixed-rate certificates of deposits. Accordingly, fair value has been estimated based upon interest rates currently being offered on deposits with similar characteristics and maturities. Investment Securities – Available for sale securities are valued based upon open-market price quotes obtained from reputable third-party brokers that actively make a market in those securities. Market pricing is based upon specific CUSIP identification for each individual security. To the extent there are observable prices in the market, the mid-point of the bid/ask price is used to determine fair value of individual securities. If that data is not available for the last 30 days, a Level 2-type matrix pricing approach based on comparable securities in the market is utilized. Level 2 pricing may include using a forward spread from the last observable trade or may use a proxy bond like a TBA mortgage to come up with a price for the security being valued. Changes in fair market value are recorded through other comprehensive loss as the securities are available for sale. Loans - Fair values of variable rate loans, which reprice frequently and with no significant change in credit risk, are based on carrying values adjusted for credit risk. Fair values for all other loans, except impaired loans, are estimated using discounted cash flows over their remaining maturities, using interest rates at which similar loans would currently be offered to borrowers with similar credit ratings and for the same remaining maturities. The allowance for loan loss is considered to be a reasonable estimate of loan discount for credit quality concerns. Impaired Loans - Fair value measurements for collateral dependent impaired loans are performed pursuant to authoritative accounting guidance and are based upon either collateral values supported by appraisals and observed market prices. Collateral dependent loans are measured for impairment using the fair value of the collateral. Changes are recorded directly as an adjustment to current earnings. Other Real Estate Owned - Nonrecurring adjustments to certain commercial and residential real estate properties classified as other real estate owned (OREO) are measured at the lower of carrying amount or fair value, less costs to sell. Fair values are generally based on third party appraisals of the property, resulting in a Level 3 classification. In cases where the carrying amount exceeds the fair value, less costs to sell, an impairment loss is recognized. Deposits – Fair values for transaction and savings accounts are equal to the respective amounts payable on demand (i.e., carrying amounts). Fair values of fixed-maturity certificates of deposit were estimated using the rates currently offered for deposits with similar remaining maturities. Junior Subordinated Debt – The fair value of the junior subordinated debt was determined based upon a discounted cash flows model utilizing observable market rates and credit characteristics for similar debt instruments. In its analysis, the Company used characteristics that market participants generally use, and considered factors specific to (a) the liability, (b) the principal (or most advantageous) market for the liability, and (c) market participants with whom the reporting entity would transact in that market. Cash flows are discounted at a rate which incorporates a current market rate for similar-term debt instruments, adjusted for credit and liquidity risks associated with similar junior subordinated debt and circumstances unique to the Company. The Company believes that the subjective nature of theses inputs, due primarily to the current economic environment, require the junior subordinated debt to be classified as a Level 3 fair value. Accrued Interest Receivable and Payable - The carrying value of these instruments is a reasonable estimate of fair value. Off-Balance Sheet Instruments - Off-balance sheet instruments consist of commitments to extend credit, standby letters of credit and derivative contracts. Fair values of commitments to extend credit are estimated using the interest rate currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present counterparties’ credit standing. There was no material difference between the contractual amount and the estimated fair value of commitments to extend credit at June 30, 2017 and December 31, 2016 . Fair values of standby letters of credit are based on fees currently charged for similar agreements. The fair value of commitments generally approximates the fees received from the customer for issuing such commitments. These fees are not material to the Company’s consolidated balance sheets and results of operations. The following table provides a description of the valuation technique, unobservable input, and qualitative information about the unobservable inputs for the Company’s assets and liabilities classified as Level 3 and measured at fair value on a recurring basis at June 30, 2017 and December 31, 2016 : June 30, 2017 December 31, 2016 Financial Instrument Valuation Technique Unobservable Input Weighted Average Financial Instrument Valuation Technique Unobservable Input Weighted Average Junior Subordinated Debt Discounted cash flow Discount Rate 5.86% Junior Subordinated Debt Discounted cash flow Discount Rate 6.46% Management believes that the credit risk adjusted spread utilized in the fair value measurement of the junior subordinated debentures carried at fair value is indicative of the nonperformance risk premium a willing market participant would require under current market conditions, that is, the inactive market. Management attributes the change in fair value of the junior subordinated debentures during the period to market changes in the nonperformance expectations and pricing of this type of debt, and not as a result of changes to our entity-specific credit risk. The narrowing of the credit risk adjusted spread above the Company’s contractual spreads has primarily contributed to the negative fair value adjustments. Generally, an increase in the credit risk adjusted spread and/or a decrease in the three month LIBOR swap curve will result in positive fair value adjustments (and decrease the fair value measurement). Conversely, a decrease in the credit risk adjusted spread and/or an increase in the three month LIBOR swap curve will result in negative fair value adjustments (and increase the fair value measurement).

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Nonrecognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Management has reviewed events occurring through the date the financial statements were issued and have identified no subsequent events requiring disclosure.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards : In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606), which creates Topic 606 and supersedes Topic 605, Revenue Recognition. In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606), which postponed the effective date of 2014-09. Multiple ASUs and interpretative guidance have been issued in connection with ASU 2014-09. The core principle of Topic 606 is that an entity recognizes 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. In general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The standard is effective for public entities for interim and annual periods beginning after December 15, 2017; early adoption is not permitted. For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company has begun their process to implement this new standard by reviewing all revenue sources to determine the sources that are in scope for this guidance. As a bank, key revenue sources, such as interest income have been identified as out of scope of this new guidance. The Company has not yet determined the financial statement impact this guidance will have. In January 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-01 Financial Instruments-Overall: Recognition and Measurements of Financial Assets and Financial Liabilities. This ASU requires equity investments to be measured at fair value, with changes in fair value recognized in net income. The amendment also simplifies the impairment assessment of equity investments for which fair value is not readily determinable by requiring an entity to perform a qualitative assessment to identify impairment. The ASU is effective for fiscal years beginning after December 15, 2017, and interim periods therein. The Company expects this ASU to impact its consolidated income and other comprehensive income disclosures for the fair value of its mutual fund investment and junior subordinated debenture. In February 2016, FASB issued ASU 2016-02, Leases (Topic 842). The FASB is issuing this Update to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. To meet that objective, the FASB is amending the FASB Accounting Standards Codification® and creating Topic 842, Leases. This Update, along with IFRS 16, Leases, are the results of the FASB’s and the International Accounting Standards Board’s (IASB’s) efforts to meet that objective and improve financial reporting. This ASU will be effective for public business entities for annual periods beginning after December 15, 2018 (i.e., calendar periods beginning on January 1, 2019), and interim periods therein. Although an estimate of the impact of the new leasing standard has not yet been determined, the Company expects a significant new lease asset and related lease liability on the balance sheet due to the number of leased branches and standalone ATM sites the Bank currently has that are accounted for under current operating lease guidance. In June 2016, FASB issued ASU 2016-13, Financial Instruments- Credit Losses (Topic 326). The FASB is issuing this Update to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The Update requires enhanced disclosures and judgments in estimating credit losses and also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. This amendment is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company has established a project team for the implementation of this new standard. The team has started by working with a vendor to put a new Allowance for Loan Loss software in place and is collecting additional historical data to estimate the impact of this standard. An estimate of the impact of this standard has not yet been determined, however, the impact is expected to be significant. As of January 1, 2017, the Company adopted the Financial Accounting Standards Board's (FASB) Accounting Standard Update ("ASU") No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09, seeks to simplify several aspects of the accounting for employee share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. As required by ASU 2016-09, all adjustments are reflected as of the beginning of the fiscal year, January 1, 2016. By applying this ASU, the Company no longer adjusts common stock for the tax impact of shares released, instead the tax impact is recognized as tax expense in the period the shares are released. This simplifies the tracking of the excess tax benefits and deficiencies, but could cause volatility in tax expense for the periods presented. The statement of cash flows has been adjusted to reflect the provisions of this ASU. The application of this ASU did not have a material impact on the financial statements. In January 2017, FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350). The FASB is issuing this Update to eliminate the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. This ASU will be effective for public business entities for annual periods beginning after December 15, 2019 (i.e. calendar periods beginning on January 1, 2020, and interim periods therein. The Company does not expect any impact on the Company's consolidated financial statements resulting from the adoption of this update. In March 2017, FASB issued ASU 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The provisions of the update require premiums recognized upon the purchase of callable debt securities to be amortized to the earliest call date in order to avoid losses recognized upon call. For public business entities that are SEC filers the amendments of the update will become effective in fiscal years beginning after December 15, 2018. The Company does not expect the requirements of this update to have a material impact on the Company’s financial position, results of operations or cash flows.
