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”)(collectively the “Company” or “USB”). Intercompany accounts and transactions have been eliminated in consolidation. These unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information on a basis consistent with the accounting policies reflected in the audited consolidated financial statements of the Company included in its 2018 Annual Report on Form 10-K. These interim consolidated financial statements do not include all of the information and footnotes required by GAAP 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. Reclassifications: Certain reclassifications have been made to prior year financial statements to conform to the classifications used in 2019. None of the reclassifications had an impact on equity or net income. Revenue from Contracts with Customers: The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. The Company’s primary sources of revenue are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Statements of Income was not necessary. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, there is little judgment involved in applying Topic 606 that significantly affects the determination of the amount and timing of revenue from contracts with customers. The Company adopted Topic 606 using the modified retrospective method on all contracts not completed as of January 1, 2018. The adoption of Topic 606 did not result in a material change to the accounting for any of the in-scope revenue streams. As such, no cumulative effect adjustment was recorded. Leases: The Company determines if an arrangement is a lease at inception. Operating leases are included in other assets and other liabilities on the consolidated balance sheets. Finance leases, if necessary, are included in property and equipment, other current liabilities, and other long-term liabilities on the consolidated balance sheets. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Recently Adopted Accounting Standards : In February 2016, FASB issued ASU 2016-02, Leases (Topic 842). The FASB issued 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. The Company adopted the New Lease Standard as of January 1, 2019 using an optional transition method, as discussed in ASU 2018-11 below, that allows application of the new leases standard at the adoption date. Under the optional transition method, financial result reported in periods prior to 2019 are unchanged. The Company also elected the package of practical expedients, which among other things did not require assessment of lease classification. See Note 7 - Leases for additional information. In July 2018, FASB issued ASU 2018-11, Leases (Topic 842), Targeted Improvements, which amends ASC 842, Leases. The amendments in this Update allowed lessors to combine lease and associated nonlease components by class of underlying asset in contract that meet certain criteria. For a lessor to qualify for this practical expedient, the lease and related nonlease components must have the same timing and pattern of transfer, and the lease component, if accounted for on a stand-alone basis, would be classified as an operating lease. Additionally the Update provided an optional method for adopting the new leasing guidance. The optional transition method allows entities to apply the new guidance at the adoption date by recognizing a cumulative-effect adjustment to the opening balance of the retained earnings, and not to restate the comparative periods presented. The Company has elected to use the practical expedient, and optional method of adoption as set-forth in this Update. See Note 7 - Leases for additional information. Recently Accounting Standards Not Yet Adopted : 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 formed a project team that is responsible for oversight of the Company’s implementation strategy for compliance with provisions of the new standard. An external provider specializing in community bank loss driver and CECL reserving model design as well as other related consulting services has been retained, and the Company has begun to evaluate potential CECL modeling alternatives. As part of this process, the Company has determined potential loan pool segmentation and sub-segmentation under CECL, as well as evaluated the key economic loss drivers for each segment. The Company presently plans to generate and evaluate model scenarios under CECL in tandem with its current reserving processes for interim and annual reporting periods in 2019. While the Company is currently unable to reasonably estimate the impact of adopting this new guidance, management expects the impact of adoption will be significantly influenced by the composition and quality of the Company’s loans and investment securities as well as the economic conditions as of the date of adoption. The Company also anticipates significant changes to the processes and procedures for calculating the reserve for credit losses and continues to evaluate the potential impact on the Company's consolidated 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 August 2018, FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this Update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, based on the concepts within FASB's Concepts Statement, including the consideration of costs and benefits. The amendment calls for the removal, modification, and addition of certain disclosure aspects to promote the appropriate exercise of discretion by entities when considering fair value measurement disclosures. The amendments of the update will become effective in fiscal years beginning after December 15, 2019. 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. In October 2018, FASB issued ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. The amendments in this Update allow entities to designate a change in the benchmark interest rate utilized for fixed-rate financial instruments, from the previously utilized LIBOR rate. For public business entities amendments of the update will become effective in fiscal years beginning after December 15, 2019. The Company continues to review the potential impact resulting from such a change. As of March 31, 2019, the Company continues to utilize the LIBOR rate for fixed-rate financial instruments. 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.

There were no other-than-temporary impairment losses for the three and six month periods ended June 30, 2019 and June 30, 2018 . At June 30, 2019 , available-for-sale securities with an amortized cost of approximately $52,747,000 (fair value of $52,704,000 ) were pledged as collateral for FHLB borrowings, securitized deposits, and public funds balances.

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 . 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. Additionally, OTTI 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. 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. At June 30, 2019 , the decline in fair value of the seven U.S. government agency securities, and the ten 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, 2019 . During the six months ended June 30, 2019 , the Company recognized $110,000 of unrealized gains related to equity securities held at June 30, 2019 in the consolidated statements of income. During the six months ended June 30, 2018 , the Company recognized $78,000 of unrealized losses related to equity securities held at June 30, 2018 in the consolidated statements of income. For the quarter ended June 30, 2019 , the Company recognized $53,000 of unrealized gains related to equity securities held at June 30, 2019 in the consolidated statements of income. For the quarter ended June 30, 2018 , the Company recognized $18,000 of unrealized losses related to equity securities held at June 30, 2018 in the consolidated statements of income. The Company had no held-to-maturity or trading securities at June 30, 2019 or December 31, 2018 .

Receivables [Abstract]
Loans	Loans Loans are comprised of the following: (in 000's) June 30, 2019 December 31, 2018 Commercial and industrial: Commercial and business loans $ 54,334 $ 55,929 Government program loans 811 1,049 Total commercial and industrial 55,145 56,978 Real estate mortgage: Commercial real estate 227,525 229,448 Residential mortgages 54,142 59,431 Home improvement and home equity loans 221 321 Total real estate mortgage 281,888 289,200 Real estate construction and development 114,611 108,795 Agricultural 52,027 61,149 Installment and student loans 69,750 71,811 Total loans $ 573,421 $ 587,933 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 9.6% of total loans at June 30, 2019 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 49.2% of total loans at June 30, 2019 , 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 and or guarantor(s). • Commercial real estate mortgage loans comprise the largest segment of this loan category and are available on all types of income producing and non-income producing 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. 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. • Home Improvement and Home Equity loans comprise a relatively small portion of total real estate mortgage loans. 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 20.0% of total loans at June 30, 2019 , 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 or from the sale of the constructed homes to individuals. Agricultural loans represent 9.1% of total loans at June 30, 2019 and are generally secured by land, equipment, inventory and receivables. Repayment is from the cash flow of the borrower. Installment loans, including student loans, represent 12.2% of total loans at June 30, 2019 and generally consist of student loans, loans to individuals for household, family and other personal expenditures, automobiles or other consumer items. See "Note 4 - Student Loans" for specific information on the student loan portfolio. 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, 2019 and December 31, 2018 , these financial instruments include commitments to extend credit of $209,335,000 and $144,643,000 , respectively, and standby letters of credit of $875,000 and $1,183,000 , 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. During the second quarter of 2018, the Bank entered into a Small Business Administration (SBA) 504 Loan Forward Purchase Commitment to buy a one hundred percent (100%) interest in up to $30 million , first mortgage, California SBA 504 loans on a flow basis with servicing released by the Seller. 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, 2019 (in 000's): June 30, 2019 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 $ — $ 75 $ — $ 75 $ 54,259 $ 54,334 $ — Government program loans — — — — 811 811 — Total commercial and industrial — 75 — 75 55,070 55,145 — Commercial real estate loans 1,016 — — 1,016 226,509 227,525 — Residential mortgages — — — — 54,142 54,142 — Home improvement and home equity loans — — — — 221 221 — Total real estate mortgage 1,016 — — 1,016 280,872 281,888 — Real estate construction and development loans — — 8,825 8,825 105,786 114,611 — Agricultural loans 180 — — 180 51,847 52,027 — Installment and student loans 303 371 341 1,015 68,510 69,525 341 Overdraft protection lines — — — — 35 35 — Overdrafts — — — — 190 190 — Total installment and student loans 303 371 341 1,015 68,735 69,750 341 Total loans $ 1,499 $ 446 $ 9,166 $ 11,111 $ 562,310 $ 573,421 $ 341 The following is a summary of delinquent loans at December 31, 2018 (in 000's): December 31, 2018 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 $ — $ — $ — $ — $ 55,929 $ 55,929 $ — Government program loans — — — — 1,049 1,049 — Total commercial and industrial — — — — 56,978 56,978 — Commercial real estate loans — — 389 389 229,059 229,448 — Residential mortgages 32 — — 32 59,399 59,431 — Home improvement and home equity loans — — — — 321 321 — Total real estate mortgage 32 — 389 421 288,779 289,200 — Real estate construction and development loans — — 8,825 8,825 99,970 108,795 — Agricultural loans — — — — 61,149 61,149 — Installment and student loans 130 139 — 269 71,362 71,631 — Overdraft protection lines — — — — 41 41 — Overdrafts — — — — 139 139 — Total installment and student loans 130 139 — 269 71,542 71,811 — Total loans $ 162 $ 139 $ 9,214 $ 9,515 $ 578,418 $ 587,933 $ — 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 loans, outside of student 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. See Note 4 - Student Loans for specific information on the student loan portfolio. 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. There were no remaining undisbursed commitments to extend credit on nonaccrual loans at June 30, 2019 or December 31, 2018 . The following is a summary of nonaccrual loan balances at June 30, 2019 and December 31, 2018 (in 000's). June 30, 2019 December 31, 2018 Commercial and business loans $ 75 $ — Government program loans — — Total commercial and industrial 75 — Commercial real estate loans — 389 Residential mortgages — — Home improvement and home equity loans — — Total real estate mortgage — 389 Real estate construction and development loans 11,562 11,663 Agricultural loans — — Installment and student loans — — Total loans $ 11,637 $ 12,052 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. The following is a summary of impaired loans at June 30, 2019 (in 000's).

(2) Information is based on the twelve month period ended December 31, 2018 . 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, 2019 and 2018 was $18,255,000 and $16,633,000 , respectively. Interest income recognized on impaired loans for the quarters ended June 30, 2019 and 2018 was approximately $197,000 and $282,000 , respectively. For impaired nonaccrual loans, interest income recognized under a cash-basis method of accounting was approximately $87,000 and $150,000 for the quarters ended June 30, 2019 and 2018 , respectively. The average recorded investment in impaired loans for the six months ended June 30, 2019 and 2018 was $18,396,000 and $16,468,000 , respectively. Interest income recognized on impaired loans for the six months ended June 30, 2019 and 2018 was approximately $334,000 and $452,000 , respectively. For impaired nonaccrual loans, interest income recognized under a cash-basis method of accounting was approximately $129,000 and $213,000 for the six months ended June 30, 2019 and 2018 , 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 and continued satisfactory performance is expected. To this end, the Company typically 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. There were no TDR additions or defaults for the three and six months ended June 30, 2019 , and the three months ended June 30, 2018 . The following tables illustrates TDR additions for the periods indicated: Six Months Ended June 30, 2018 ($ 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 — — — — — Commercial real estate term loans — — — — — Single family residential loans — — — — — Home improvement and home equity loans — — — — — Real estate construction and development loans — — — 1 310 Agricultural loans — — — — — Installment and student loans — — — — — Overdraft protection lines — — — — — Total loans — $ — $ — 1 $ 310 The Company makes various types of concessions when structuring TDRs including rate discounts, payment extensions, and other-than-temporary 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 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. Weaknesses in special mention loans may, if not checked or corrected, weaken the asset or inadequately protect the Company’s credit position at some future date. Special mention loans are often loans with weaknesses inherent from the loan origination, loan servicing, and perhaps some technical deficiencies. The main theme in special mention credits is the distinct probability that the classification will deteriorate to a more adverse class if the noted deficiencies are not addressed by the loan officer or loan management. - Grade 7 – This grade includes “substandard” loans which are inadequately supported by the current sound net worth and paying capacity of the borrower or of the collateral pledged, if any. Substandard loans have a well-defined weakness or weaknesses that may impair the regular liquidation of the debt. Substandard loans exhibit a distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Substandard loans also include impaired loans. - Grade 8 – This grade includes “doubtful” loans which exhibit the same characteristics as the Substandard loans with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors, which may work to the advantage and strengthening of the loan, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include a proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral and refinancing plans. - Grade 9 – This grade includes loans classified “loss” which ar

Receivables [Abstract]
Student Loans	Student Loans Included in installment loans are $65,935,000 and $68,221,000 in student loans at June 30, 2019 and December 31, 2018 , respectively, made to medical and pharmacy school students. Upon graduation the loan is automatically placed on deferment for 6 months. This may be extended up to 48 months for graduates enrolling in Internship, Medical Residency or Fellowship. As approved, the student may receive additional deferment for hardship or administrative reasons in the form of forbearance for a maximum of 24 months throughout the life of the loan. Accrued interest on loans that had not entered repayment status totaled $7,767,000 at June 30, 2019 and $5,866,000 at December 31, 2018 . At June 30, 2019 there were 522 loans within repayment, deferment, and forbearance which represented $12,783,000 , $2,887,000 , and $6,298,000 , respectively. At December 31, 2018 , there were 595 loans within repayment, deferment, and forbearance which represented $15,526,000 , $1,945,000 and $7,336,000 , respectively. As of June 30, 2019 the risks within the student loan portfolio were assessed and it was determined that along with the calculation of the general reserve of $769,000 , an additional allowance of $1,175,000 was appropriate, for a total reserve against the student loan portfolio of $1,944,000 . The additional allowance was determined as a percentage of the forbearance loan total and a 100% reserve against student loans rated special mention. The percentage utilized for the calculation against forbearance loans was increased during the period. At December 31, 2018 the general reserve for the student loan portfolio was $880,000 with an additional allowance of $640,000 , for a total reserve against the student loan portfolio of $1,520,000 . There were no TDRs within the portfolio as of June 30, 2019 or December 31, 2018 . Reunion Student Loan Finance Corporation (RSLFC) is the third-party servicer for the student loan portfolio. RSLFC's services include application administration, processing, approval, documenting, funding, and collection. They also provide borrower file custodial responsibilities. Except in cases where applicants/loans do not meet program requirements, or extreme delinquency, RSLFC is responsible for complete program management. RSLFC is paid a monthly servicing fee based on the outstanding principal balance. Interest income on the student loan portfolio offsets this expense, and is presented net of expense within loan interest income on the consolidated statements of income. The following tables summarize the credit quality indicators for outstanding student loans as of June 30, 2019 and December 31, 2018 (in 000's, except for number of borrowers): June 30, 2019 December 31, 2018 Number of Loans Amount Accrued Interest Number of Loans Amount Accrued Interest School 740 $ 28,806 $ 4,586 1,056 $ 42,852 $ 5,494 Grace 321 15,161 2,816 23 562 81 Repayment 307 12,783 99 366 15,526 118 Deferment 70 2,887 199 48 1,945 79 Forbearance 145 6,298 166 181 7,336 212 Total 1,583 $ 65,935 $ 7,866 1,674 $ 68,221 $ 5,984 School - The time in which the borrower is still actively in school at least half time. No payments are expected during this stage, though the borrower may begin immediate payments. Grace - A six month period of time granted to the borrower immediately upon graduation, or if deemed no longer an active student. Interest continues to accrue. Upon completion of the six month grace period the loan is transferred to repayment status. Additionally, if applicable, this status may represent a borrower activated to military duty while in their in-school period, they will be allowed to return to that status once their active duty has expired. The borrower must return to an at least half time status within six months of the active duty end date in order to return to an in-school status. Repayment - The time in which the borrower is no longer actively in school at least half time, and has not received an approved grace, deferment, or forbearance. Regular payment is expected from these borrowers under an allotted payment plan. Deferment - May be granted up to 48 months for borrowers who have begun the repayment period on their loans but are (1) actively enrolled in an eligible school at least half time, or (2) are actively enrolled in an approved and verifiable medical residency, internship, or fellowship program. Forbearance - The period of time during which the borrower may postpone making principal and interest payments, which may be granted for either hardship or administrative reasons. Interest will continue to accrue on loans during periods of authorized forbearance. If the borrower is delinquent at the time the forbearance is granted, the delinquency will be covered by the forbearance and all accrued and unpaid interest from the date of delinquency or if none, from the date of beginning of the forbearance period, will be capitalized at the end of each forbearance period. The term of the loan will not change and payments may be increased to allow the loan to pay off in the required time frame. A forbearance that results in only a delay in payment considered insignificant, is not a concessionary change in terms provided the borrower affirms the obligation. Forbearance is not an uncommon status designation, this designation is standard industry practice, and is consistent with the succession of students migrating to employed medical professionals. Student Loan Aging Student loans are generally charged off at the end of the month during which an account becomes 120 days contractually past due. Accrued but unpaid interest related to charged off student loans is reversed and charged against interest income. For the six months ended June 30, 2019 , $4,000 in accrued interest receivable was reversed, due to charge-offs of $103,000 within the student loan portfolio. As of December 31, 2018 , $26,000 in accrued interest receivable was reversed, due to charge-offs of $388,000 within the student loan portfolio. The following tables summarize the student loan aging for loans in repayment and forbearance as of June 30, 2019 and December 31, 2018 (in 000's, except for number of borrowers): June 30, 2019 December 31, 2018 Number of Borrowers Amount Number of Borrowers Amount Current or less than 31 days 201 $ 18,066 248 $ 22,534 31 - 60 days 6 303 2 130 61 - 90 days 5 371 4 140 91 - 120 days 4 281 1 58 121-180 days 1 60 — — Total 217 $ 19,081 255 $ 22,862

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, 2019 and December 31, 2018 , the Company had no recorded valuation allowance. The Company is no longer subject to IRS examination for years before 2014. 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, 2019 and 2018 were insignificant. The Company reported a provision for income taxes of $3,292,000 for the six months ended June 30, 2019 as compared to the $2,653,000 provision reported in the comparable period of 2018 . The effective tax rate was 28.89% for the six months ended June 30, 2019 as compared to 28.83% for the comparable period of 2018 .

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 any time 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, 2019 . 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, 2019 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 4.88% discount rate used represents what a market participant would consider under the circumstances based on current market assumptions. At June 30, 2019 , the total cumulative gain recorded on the debt is $2,086,000 . The net fair value calculation performed as of June 30, 2019 resulted in a net pretax loss adjustment of $336,000 ( $205,000 , net of tax) for the six months ended June 30, 2019 , compared to a net pretax loss adjustment of $366,000 ( $224,000 , net of tax) for the six months ended June 30, 2018 . For the six months ended June 30, 2019 , the net $336,000 ( $205,000 , net of tax) fair value loss adjustment was separately presented as a $911,000 gain ( $642,000 , net of tax) recognized on the consolidated statements of income, and a $1,247,000 loss ( $878,000 , net of tax) associated with the instrument specific credit risk recognized in other comprehensive income. For the six months ended June 30, 2018 , the net $366,000 ( $224,000 , net of tax) fair value loss adjustment was separately presented as a $661,000 loss ( $464,000 , net of tax) recognized on the consolidated statements of income, and a $295,000 gain ( $207,000 , net of tax) associated with the instrument specific credit risk recognized in other comprehensive income. The net fair value calculation performed as of June 30, 2019 resulted in a net pretax loss adjustment of $45,000 ( $27,000 , net of tax) for the three months ended June 30, 2019 compared to a net pretax loss adjustment of $464,000 ( 283,000 , net of tax) for the three months ended June 30, 2018 . For the three months ended June 30, 2019 , the net $45,000 ( $27,000 , net of tax) fair value loss adjustment was separately presented as a $497,000 gain ( $350,000 , net of tax) recognized on the consolidated statements of income, and a $542,000 loss ( $382,000 , net of tax) associated with the instrument specific credit risk recognized in other comprehensive income. For the three months ended June 30, 2018 , the net $464,000 ( 283,000 , net of tax) fair value loss adjustment was separately presented as a $192,000 loss ( $135,000 , net of tax) recognized on the consolidated statements of income, and a $272,000 loss ( $191,000 , net of tax) associated with the instrument specific credit risk recognized in other comprehensive 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, 2019 (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 $ 309,460 $ 309,460 $ 309,460 $ — $ — Investment securities 63,632 59,863 3,769 59,863 — Loans 564,358 552,173 — — 552,173 Accrued interest receivable 10,314 10,314 — 10,314 — Financial Liabilities: Deposits: Noninterest-bearing 304,172 304,172 304,172 — — NOW and money market 404,416 404,416 404,416 — — Savings 92,274 92,274 92,274 — — Time deposits 70,053 69,735 — — 69,735 Total deposits 870,915 870,597 800,862 — 69,735 Junior subordinated debt 10,496 10,496 — — 10,496 Accrued interest payable 77 77 — 77 — December 31, 2018 (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 $ 220,337 $ 220,337 $ 220,337 $ — $ — Investment securities 70,085 70,085 3,659 66,426 — Loans 579,419 566,195 — — 566,195 Accrued interest receivable 8,341 8,341 — 8,341 — Financial Liabilities: Deposits: Noninterest-bearing 292,720 292,720 292,720 — — NOW and money market 340,445 340,445 340,445 — — Savings 90,046 90,046 90,046 — — Time deposits 82,432 81,745 — — 81,745 Total deposits 805,643 804,956 723,211 — 81,745 Junior subordinated debt 10,155 10,155 — — 10,155 Accrued interest payable 57 57 — 57 — 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 investment securities 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 six months ended June 30, 2019 . The following methods and assumptions were used in estimating the fair values of financial instruments measured at fair value on a recurring and non-recurring basis: Investment Securities – Available for sale and marketable equity 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. 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. 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. 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, 2019 and December 31, 2018 : June 30, 2019 December 31, 2018 Financial Instrument Valuation Technique Unobservable Input Weighted Average Financial Instrument Valuation Technique Unobservable Input Weighted Average Junior Subordinated Debt Discounted cash flow Discount rate 4.88% Junior Subordinated Debt Discounted cash flow Discount rate 5.86% 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). The increase in discount rate between the periods ended June 30, 2019 and December 31, 2018 is primarily due to increases in rates for similar debt instruments.

Recently Adopted and Not Yet Adopted Accounting Standards	Recently Adopted Accounting Standards : In February 2016, FASB issued ASU 2016-02, Leases (Topic 842). The FASB issued 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. The Company adopted the New Lease Standard as of January 1, 2019 using an optional transition method, as discussed in ASU 2018-11 below, that allows application of the new leases standard at the adoption date. Under the optional transition method, financial result reported in periods prior to 2019 are unchanged. The Company also elected the package of practical expedients, which among other things did not require assessment of lease classification. See Note 7 - Leases for additional information. In July 2018, FASB issued ASU 2018-11, Leases (Topic 842), Targeted Improvements, which amends ASC 842, Leases. The amendments in this Update allowed lessors to combine lease and associated nonlease components by class of underlying asset in contract that meet certain criteria. For a lessor to qualify for this practical expedient, the lease and related nonlease components must have the same timing and pattern of transfer, and the lease component, if accounted for on a stand-alone basis, would be classified as an operating lease. Additionally the Update provided an optional method for adopting the new leasing guidance. The optional transition method allows entities to apply the new guidance at the adoption date by recognizing a cumulative-effect adjustment to the opening balance of the retained earnings, and not to restate the comparative periods presented. The Company has elected to use the practical expedient, and optional method of adoption as set-forth in this Update. See Note 7 - Leases for additional information. Recently Accounting Standards Not Yet Adopted : 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 formed a project team that is responsible for oversight of the Company’s implementation strategy for compliance with provisions of the new standard. An external provider specializing in community bank loss driver and CECL reserving model design as well as other related consulting services has been retained, and the Company has begun to evaluate potential CECL modeling alternatives. As part of this process, the Company has determined potential loan pool segmentation and sub-segmentation under CECL, as well as evaluated the key economic loss drivers for each segment. The Company presently plans to generate and evaluate model scenarios under CECL in tandem with its current reserving processes for interim and annual reporting periods in 2019. While the Company is currently unable to reasonably estimate the impact of adopting this new guidance, management expects the impact of adoption will be significantly influenced by the composition and quality of the Company’s loans and investment securities as well as the economic conditions as of the date of adoption. The Company also anticipates significant changes to the processes and procedures for calculating the reserve for credit losses and continues to evaluate the potential impact on the Company's consolidated 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 August 2018, FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this Update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, based on the concepts within FASB's Concepts Statement, including the consideration of costs and benefits. The amendment calls for the removal, modification, and addition of certain disclosure aspects to promote the appropriate exercise of discretion by entities when considering fair value measurement disclosures. The amendments of the update will become effective in fiscal years beginning after December 15, 2019. 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. In October 2018, FASB issued ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. The amendments in this Update allow entities to designate a change in the benchmark interest rate utilized for fixed-rate financial instruments, from the previously utilized LIBOR rate. For public business entities amendments of the update will become effective in fiscal years beginning after December 15, 2019. The Company continues to review the potential impact resulting from such a change. As of March 31, 2019, the Company continues to utilize the LIBOR rate for fixed-rate financial instruments. 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.
