Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of Pacific Premier Bancorp, Inc. (the “Corporation”) and its wholly owned subsidiaries, including Pacific Premier Bank (the “Bank”) (collectively, the “Company,” “we,” “our” or “us”). All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the unaudited consolidated financial statements reflect all normal recurring adjustments that are necessary for a fair presentation of the results for the interim periods presented. The results of operations for the three and six month ended June 30, 2019 are not necessarily indicative of the results that may be expected for any other interim period or the full year ending December 31, 2019 . Certain items in the prior year financial statements were reclassified to conform to the current year presentation. Reclassification had no effect on prior year net income or stockholders’ equity. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 (the “ 2018 Annual Report”). The Company accounts for its investments in its wholly owned special purpose entities, PPBI Trust I, Heritage Oaks Capital Trust II, Mission Community Capital Trust I, Santa Lucia Bancorp (CA) Capital Trust and First Commerce Bancorp Trust I, under the equity method whereby the subsidiary’s net earnings are recognized in the Company’s statement of income.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Accounting Standards Adopted in 2019 In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchase Callable Debt Securities . This Update amends guidance on the amortization period of premiums on certain purchased callable debt securities. The amendments shorten the amortization period of premiums on purchased callable debt securities to the earliest call date. This Update should be applied on a modified retrospective basis through a cumulative-effect adjustment to beginning retained earnings. The effective date of ASU 2017-08 is for interim and annual reporting periods beginning after December 15, 2018. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , ASU 2018-11, Leases (Topic 842): Targeted Improvements , ASU 2018-10, Codification Improvements to Topic 842, Leases . This Update is being issued to increase the transparency and comparability around lease obligations. Previously unrecorded off-balance sheet obligations and corresponding rights to use underlying leased assets will now be recorded in the consolidated financial statements, accompanied by enhanced qualitative and quantitative disclosures in the notes to the consolidated financial statements. The Update is generally effective for public business entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842): Targeted Improvements . ASU 2018-10 provides improvements related to ASU 2016-02 to increase stakeholders’ awareness of the amendments to Topic 842 and to expedite the improvements. The amendments affect narrow aspects of the guidance issued in ASU 2016-02. ASU 2018-11 allows entities adopting ASU 2016-02 to choose an additional transition method, under which an entity initially applies the accounting guidance for leases under Topic 842 at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, ASU 2018-11 allows an entity electing this additional transition method to continue to present comparative period financial statements in accordance with Topic 840 (current U.S. GAAP). ASU 2018-11 also allows lessors to not separate non-lease components from the associated lease component if certain conditions are met. The amendments in these updates became effective for annual periods as well as interim periods within those annual periods beginning after December 15, 2018. The Company elected to apply the transition provisions of Topic 842 using the alternative transition method whereby comparative periods are not restated. The Company also elected to adopt the “package” of practical expedients in its transition to Topic 842, as specified in Accounting Standard Codification (“ASC”) 842-10-65. The results of this policy election are that the Company reflected the provisions of Topic 842 in its consolidated financial statements for the first time as of and for the period ended March 31, 2019 (the period of adoption). The Company measured and recorded liabilities to make lease payments as well as right-of-use assets in the period of adoption for leases that existed as of the transition date, and will continue to present all comparative periods under Topic 840. Under this elected transition method, the Company is not required to reassess the following as part of its transition to Topic 842: (1) whether any expired or existing contracts contain leases, (2) lease classifications for any existing or expired leases and (3) initial direct costs for any existing leases. Additionally, the Company elected to apply the use of hindsight in its assessment of the term for its leases upon transition, which allows for consideration of the Company’s option to extend or terminate a lease. The Company adopted the provisions of Topic 842 on January 1, 2019, and in its transition to Topic 842, the Company initially recorded a liability to make future lease payments of approximately $45.7 million and right-of-use assets of approximately $43.8 million . The difference of $1.9 million is the accounting adjustments previously recorded under Topic 840 and Topic 805, as required by transition guidance in ASC 842-10-65. The Company was not required to record a cumulative effect adjustment to the opening balance of retained earnings as part of its transition to Topic 842. The Company’s evaluation of lease obligations and service agreements under the new standard included an assessment of the appropriate classification and related accounting of each lease agreement, a review of applicability of the new standard to existing service agreements and gathering all essential lease data to facilitate the application of the new standard. The Company’s review indicated that all of its leases are classified as operating leases or short-term leases. In accordance with the provisions of Topic 842, liabilities to make future lease payments and right-of-use assets are only recorded for leases that are not considered short-term (leases with an original term of greater than 12 months). The Company records expense for its leases on a straight-line basis in accordance with the requirements under Topic 842 for operating leases. The Company’s expense recognition for its operating leases (including short-term leases) under Topic 842 has not differed significantly from that recorded under Topic 840. Right-of-use assets for operating leases are amortized over the lease term and liabilities to make future lease payments are accounted for using the interest method, both in accordance with Topic 842. Please also refer to Note 13 - Leases for additional information related to the Company’s leases. Recent Accounting Guidance Not Yet Effective In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments . This Update was issued as part of an ongoing project on the FASB’s agenda for improving the Codification or correcting for its unintended application. The FASB issued this Update, which is specific to Updates: 2016-13, Financial Instruments- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , and 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. Improvements within this Update include: (1) Allowing the measurement of credit losses on accrued interest receivable balances to be determined separately from the other components of the amortized cost basis of associated financial assets. (2) Allow entities to make an accounting policy election to not measure credit losses on accrued interest receivable balances if the entity writes off the uncollectable accrued interest balances in a timely manner through a reversal of interest income or through the recognition of credit loss expense, or both. (3) Allow entities to make an accounting policy election to present accrued interest receivable balances and any related allowance for credit losses separately from the associated financial assets on the balance sheet (not including them as part of the associated financial asset’s amortized cost). (4) Allow entities to elect a practical expedient to disclose separately the total amount of accrued interest included in the amortized cost basis as a single balance to meet certain disclosure requirements. (5) Require that entities reverse from earnings any allowance for credit losses or valuation allowance previously measured on a loan or debt security upon the reclassification of the loan or debt security from one classification or category to another (such as from held for investment to held for sale), and apply the applicable measurement guidance with the new classification or category. (6) Clarify that an entity should include an estimate for recoveries of amounts previously written off in its estimation of the allowance for credit losses. (7) Allow entities to use future interest rate environment projections in the determination of the allowance for credit losses under the discounted cash flow method. (8) Allow an entity to make an accounting policy election to adjust the effective interest rate used to discount expected future cash flows for expected prepayments on financial assets within the scope of ASC 326-20 and on available for sale debt securities within the scope of ASC 326-30 to appropriately isolate credit risk in the determination of the allowance for credit losses. (9) Clarify that an entity should consider, when determining the contractual term of a financial asset, extension or renewal options that are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the entity. (10) Clarify the guidance by specifically requiring that an entity re-measure an equity security without readily determinable fair value at fair value when an orderly transaction is identified for an identical or similar investment of the same issuer in accordance with Topic 820. That is, the amendments clarify that the measurement alternative is a nonrecurring fair value measurement. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company is currently evaluating the effects of this Update on its financial statements and disclosures. In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842): Codification Improvements. This Update provides clarification on certain aspects of an entity’s implementation of Topic 842 including those that relate to: (1) Determining the fair value of the underlying asset by lessors that are not manufacturers or dealers. The amendments related to this item carry forward from Topic 840 to Topic 842 an exception that allows lessors who are not manufacturers or dealers to use the cost of the underlying asset as its fair value. (2) Presentation on the statement of cash flows - sales-type and direct financing leases. The amendments related to this item clarify that all principal payments received on leases by lessors in sales-type or direct financing lease transactions should be reflected in investing activities for entities such as depository and lending institutions within in the scope of Topic 942. (3) Transition disclosures related to Topic 250, Accounting Changes and Error Corrections. The amendments related to this item clarify the FASB’s original intent by explicitly providing an exception to the paragraph 250-10-50-3 interim disclosure requirements in the Topic 842 transition disclosure requirements, which would otherwise require interim disclosures after the date of adoption of Topic 842 related to the impacts of the change on: (a) income from continuing operations, (b) net income, (c) any other financial statement line item and (d) any affected per-share amounts. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted. The Company does not believe the effects of this ASU will have a material effect on the Company’s financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement . The amendments in this Update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement . The following disclosure requirements for public companies were removed from Topic 820: • The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy • The policy for timing of transfers between levels • The valuation processes for Level 3 fair value measurements The following disclosure requirements for public companies were modified in Topic 820: • The amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date The following disclosure requirements for public companies were added to Topic 820: • The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period • The range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. In addition, an entity may early adopt any of the removed or modified disclosures immediately and delay adoption of the new disclosures until the effective date. The Company is currently evaluating the effects of ASU 2018-13 on its financial statements and disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This Update replaces the incurred loss impairment model in current U.S. GAAP with a model that reflects current expected credit losses (“CECL”). The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. CECL also requires credit losses on available-for-sale debt securities be measured through an allowance for credit losses when the fair value is less than the amortized cost basis. It also applies to off-balance sheet credit exposures. The Update requires that all expected credit losses for financial assets held at the reporting date be measured based on historical experience, current conditions and reasonable and supportable forecasts. The Update also requires enhanced disclosure, including qualitative and quantitative disclosures that provide additional information about significant estimates and judgments used in estimating credit losses. For public business entities, the Update is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. In May 2019, the FASB issued ASU 2019-05, Financial Instruments-Credit Losses (Topic 326):Targeted Transition Relief, to allow companies to irrevocably elect, upon adoption of ASU 2016-13, the fair value option for financial instruments that (1) were previously recorded at amortized cost and (2) are within the scope of the credit losses guidance in ASC 326-20, (3) are eligible for the fair value option under ASC 825-10, and (4) are not held-to-maturity debt securities. Entities are required to make this election on an instrument-by-instrument basis. The effective date will be the same as the effective date in ASU 2016-13. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures, and has contracted with an industry expert to: (1) develop a new expected loss model with supportable assumptions, (2) identify data, reporting and disclosure gaps, (3) provide quantitative modeling and (4) assess, develop and document updates to accounting policies, new processes and controls. The Company’s CECL Committee and related sub-committees and working groups, made up of members of finance, credit, lending, internal audit and risk management continue with coordinated efforts around model development, which have become more focused on model refinements, including those related to software applications that drive model calculations. The Company’s CECL Committee has also begun the process of reviewing and analyzing certain elements of model output. Other workflows currently in process or scheduled to begin soon, and driven by the Company’s CECL Committee include: (1) development of model documentation, (2) model validation, (3) analysis and documentation of model data requirements, (4) identification of risk in the modeling process and assessment of existing controls and the design of new controls and (5) development of required policies, procedures and disclosures. The magnitude of the adjustment and the overall impact of the new guidance on the Company’s consolidated financial statements cannot yet be reasonably estimated.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Our accounting policies are described in Note 1. Description of Business and Summary of Significant Accounting Policies , of our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018 as filed with the Securities and Exchange Commission (“Form 10-K”). Select policies have been reiterated below that have a particular affiliation to our interim financial statements. Revenue Recognition – The Company accounts for certain of its revenue streams in accordance with ASC 606 - Revenue from Contracts with Customers . Revenue streams within the scope of and accounted for under ASC 606 include: service charges and fees on deposit accounts, debit card interchange fees, fees from other services the Bank provides its customers and gains and losses from the sale of other real estate owned and property, premises and equipment. ASC 606 requires revenue to be recognized when the Company satisfies related performance obligations by transferring to the customer a good or service. The recognition of revenue under ASC 606 requires the Company to first identify the contract with the customer, identify the performance obligations, determine the transaction price, allocate the transaction price to the performance obligations and finally recognize revenue when the performance obligations have been satisfied and the good or service has been transferred. The majority of the Company’s contracts with customers associated with revenue streams that are within the scope of ASC 606 are considered short-term in nature and can be canceled at any time by the customer or the Bank, such as a deposit account agreement. Other more significant revenue streams for the Company such as interest income on loans and investment securities are specifically excluded from the scope of ASC 606 and are accounted for under other applicable U.S. GAAP. Goodwill and Core Deposit Intangible – Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exist that indicate the necessity for such impairment tests to be performed. The Company has selected the fourth quarter as the period to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Core deposit intangible assets arising from whole bank acquisitions are amortized on either an accelerated basis, reflecting the pattern in which the economic benefits of the intangible assets is consumed or otherwise used up, or on a straight-line amortization method over their estimated useful lives, which range from 6 to 10 years . Leases – The Company accounts for its leases in accordance with ASC 842, which requires the Company to record liabilities for future lease obligations as well as assets representing the right to use the underlying leased asset. Leases with a term of 12 months or less are accounted for using straight-line expense recognition with no liability or asset being recorded for such leases. Other than short-term leases, the Company classifies its leases as either finance leases or operating leases. Leases are classified as finance leases when any of the following are met: (a) the lease transfers ownership of the underlying asset to the Company by the end of the lease term, (b) the lease contains an option to purchase the underlying asset that the Company is reasonably certain to exercise, (c) the term of the lease represents a major part of the remaining life of the underlying asset, (d) the present value of the future lease payments equals or exceeds substantially all of the fair value of the underlying asset or (e) the underling leased asset is expected to have no alternative use to the lessor at the end of the lease term due to its specialized nature. When the Company’s assessment of a lease does not meet the foregoing criteria, and the term of the lease is in excess of 12 months, the lease is classified as an operating lease. Liabilities to make lease payments and right-of-use assets are determined based on the total contractual base rents for each lease, discounted at the rate implicit in the lease or at the Company’s estimated incremental borrowing rate if the rate is not implicit in the lease. The Company measures future base rents based on the minimum payments specified in the lease agreement, giving consideration for periodic contractual rent increases which are based on an escalation rate or a specified index. When future rent payments are based on an index, the Company uses the index rate observed at the time of lease commencement to measure future lease payments. Liabilities to make lease payments are accounted for using the interest method, which are reduced by periodic rent payments, net of interest accretion. Right-of-use assets for finance leases are amortized on a straight-line basis over the term of the lease, while right-of-use assets for operating leases are amortized over the term of the lease by amounts that represent the difference between periodic straight-line lease expense and periodic interest accretion on the related liability to make lease payments. Expense recognition for finance leases is representative of the sum of periodic amortization of the associated right-of-use asset as well as the periodic interest accretion on the liability to make lease payments. Expense recognition for operating leases is recorded on a straight-line basis. As of June 30, 2019, all of the Company’s leases were classified as either operating leases or short-term leases. From time to time the Company leases portions of the space it leases to other parties through sublease transactions. Income received from these transactions is recorded on a straight-line basis over the term of the sublease. Use of Estimates

Business Combinations [Abstract]
Acquisitions	Acquisitions Grandpoint Capital, Inc. Acquisition Effective as of July 1, 2018, the Company completed the acquisition of Grandpoint Capital, Inc. (“Grandpoint”), the holding company of Grandpoint Bank, a California-chartered bank, with $3.1 billion in total assets, $2.4 billion in gross loans and $2.5 billion in total deposits at June 30, 2018. Pursuant to the terms of the merger agreement, each outstanding share of Grandpoint voting common stock and Grandpoint non-voting common stock was converted into the right to receive 0.4750 shares of the Corporation’s common stock. The final value of the total transaction consideration was approximately $602.2 million , after approximately $28.1 million in aggregate cash consideration payable to holders of Grandpoint share-based compensation awards by Grandpoint. The transaction consideration represented the issuance of 15,758,089 shares of the Corporation’s common stock, valued at $38.15 per share, which was the closing price of the Corporation’s common stock on June 29, 2018, the last trading day prior to the consummation of the Merger. Goodwill in the amount of $312.6 million was recognized in the Grandpoint acquisition. Goodwill represents the future economic benefits arising from net assets acquired that are not individually identified and separately recognized and is attributable to synergies expected to be derived from the combination of the two entities. Goodwill recognized in this transaction is not deductible for income tax purposes. The following table represents the assets acquired and liabilities assumed of Grandpoint as of July 1, 2018 and the fair value adjustments and amounts recorded by the Company in 2018 under the acquisition method of accounting: Grandpoint Book Value Fair Value Adjustments Fair Value ASSETS ACQUIRED (dollars in thousands) Cash and cash equivalents $ 147,551 $ — $ 147,551 Investment securities 395,905 (3,047 ) 392,858 Loans, gross 2,404,042 (51,325 ) 2,352,717 Allowance for loan losses (18,665 ) 18,665 — Fixed assets 6,015 3,107 9,122 Core deposit intangible 5,093 66,850 71,943 Deferred tax assets 14,185 (9,157 ) 5,028 Other assets 97,441 (436 ) 97,005 Total assets acquired $ 3,051,567 $ 24,657 $ 3,076,224 LIABILITIES ASSUMED Deposits $ 2,506,663 $ 266 $ 2,506,929 Borrowings 255,155 (232 ) 254,923 Other liabilities 23,687 1,172 24,859 Total liabilities assumed 2,785,505 1,206 2,786,711 Excess of assets acquired over liabilities assumed $ 266,062 $ 23,451 289,513 Consideration paid 602,152 Goodwill recognized $ 312,639 Such fair values are preliminary estimates and subject to refinement for up to one year after the closing date of acquisition as additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. Since the acquisition, the Company has made a net adjustment of $580,000 related to loans, deferred tax assets and other assets. During the second quarter of 2019, the Company finalized its fair values with this acquisition. The Company accounted for this transaction under the acquisition method of accounting in accordance with ASC 805, Business Combinations , which requires purchased assets and liabilities assumed to be recorded at their respective fair values at the date of acquisition. The loan portfolios of Grandpoint was recorded at fair value at the date of each acquisition. A valuation of Grandpoint’s loan portfolio was performed by a third party as of the acquisition dates to assess the fair value of the loan portfolio. The loan portfolio was both segmented into two groups; loan with credit deterioration and loans without credit deterioration, and then split further by loan type. The fair value was calculated on an individual loan basis using a discounted cash flow analysis. The discount rate utilized was based on a weighted average cost of capital, considering the cost of equity and cost of debt. Also factored into the fair value estimates were loss rates, recovery periods and prepayment rates, all of which were based on industry standards. The Company also determined the fair value of the core deposit intangible, securities, real property, leases, deposits and long-term borrowings with the assistance of third-party valuations. The fair value of other real estate owned (“OREO”) was based on recent appraisals of the properties less estimated costs to sell. The core deposit intangible on non-maturing deposits was determined by evaluating the underlying characteristics of the deposit relationships, including customer attrition, deposit interest rates, service charge income, overhead expense and costs of alternative funding. Since the fair value of intangible assets are calculated as if they were stand-alone assets, the presumption is that a hypothetical buyer of the intangible asset would be able to take advantage of potential tax benefits resulting from the asset purchase. The value of the benefit is the present value over the period of the tax benefit, using the discount rate applicable to the asset. In determining the fair value of certificates of deposit, a discounted cash flow analysis was used, which involved present valuing the contractual payments over the remaining life of the certificates of deposit at market-based interest rates. For loans acquired from Grandpoint, the contractual amounts due, expected cash flows to be collected, interest component and fair value as of acquisition date was as follows: Grandpoint Acquired Loans (dollars in thousands) Contractual amounts due $ 3,496,905 Cash flows not expected to be collected 39,071 Expected cash flows 3,457,834 Interest component of expected cash flows 1,105,117 Fair value of acquired loans $ 2,352,717 In accordance with U.S. GAAP, there was no carryover of the allowance for loan losses that had been previously recorded by Grandpoint. The operating results of the Company for the three and six months ended June 30, 2019 include the operating results of Grandpoint. The following table presents the unaudited pro forma information for the net interest and other income, net income and earnings per share as if the acquisition was effective as of January 1, 2018 for the periods indicated and includes certain nonrecurring adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods.

At June 30, 2019 , the Company had an accumulated other comprehensive income of $31.4 million , or $22.4 million net of tax, compared to an accumulated other comprehensive loss of $7.9 million , or $5.6 million net of tax, at December 31, 2018 . Beginning the first quarter of March 31, 2019, the Bank no longer had HOA reverse repurchase agreements and unpledged all the supporting mortgage-backed securities. At December 31, 2018 , mortgage-backed securities with an estimated par value of $20.3 million and a fair value of $20.9 million were pledged as collateral for the Bank’s HOA reverse repurchase agreements, which totaled $75,000 . The average balance of repurchase agreement facilities was $15.0 million during the year ended December 31, 2018 . At June 30, 2019 and December 31, 2018 , there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of stockholders’ equity. The Company reviews individual securities classified as available-for-sale to determine whether a decline in fair value below the amortized cost basis is temporary because (i) those declines were due to interest rate changes and not to a deterioration in the creditworthiness of the issuers of those investment securities, and (ii) we have the ability to hold those securities until there is a recovery in their values or until their maturity. If it is probable that the Company will be unable to collect all amounts due according to contractual terms of the debt security not impaired at acquisition, an other-than-temporary impairment (“OTTI”) shall be considered to have occurred. If an OTTI occurs, the cost basis of the security will be written down to its fair value as the new cost basis and the write down accounted for as a realized loss. There was no OTTI for the six months ended June 30, 2019 and June 30, 2018 . The table below shows the number, fair value and gross unrealized holding losses of the Company’s investment securities by investment category and length of time that the securities have been in a continuous loss position.

(2) Includes second trust deeds. (3) Total gross loans held for investment for June 30, 2019 and December 31, 2018 are net of the unaccreted fair value net purchase discounts of $52.0 million and $61.0 million , respectively. Loans Serviced for Others The Company generally retains the servicing rights of the guaranteed portion of Small Business Administration (“SBA”) loans sold, for which the Company records a servicing asset at fair value within its other assets category. At June 30, 2019 and December 31, 2018 , the servicing asset totaled $8.0 million and $8.5 million , respectively, and was included in other assets. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is recognized through a valuation allowance, to the extent the fair value is less than the carrying amount. At June 30, 2019 and December 31, 2018 , the Company determined that no valuation allowance was necessary. Loans serviced for others are not included in the accompanying consolidated statements of financial condition. The unpaid principal balance of loans and participations serviced for others were $689.1 million at June 30, 2019 and $635.3 million at December 31, 2018 , including SBA participations serviced for others totaling $493.9 million at June 30, 2019 and $519.8 million at December 31, 2018 . Concentration of Credit Risk As of June 30, 2019 , the Company’s loan portfolio was primarily collateralized by various forms of real estate and business assets located predominately in California. The Company’s loan portfolio contains concentrations of credit in multi-family real estate, commercial non-owner occupied real estate, commercial owner occupied real estate loans and commercial and industrial business loans. The Bank maintains policies approved by the Bank’s Board of Directors (the “Bank Board”) that address these concentrations and diversifies its loan portfolio through loan originations, purchases and sales to meet approved concentration levels. While management believes that the collateral presently securing these loans is adequate, there can be no assurances that a significant deterioration in the California real estate market or economy would not expose the Company to significantly greater credit risk. Under applicable laws and regulations, the Bank may not make secured loans to one borrower in excess of 25% of the Bank’s unimpaired capital plus surplus and likewise in excess of 15% of the Bank’s unimpaired capital plus surplus for unsecured loans. These loans-to-one borrower limitations result in a dollar limitation of $547.0 million for secured loans and $328.2 million for unsecured loans at June 30, 2019 . In order to manage concentration risk, the Bank maintains a house lending limit well below these statutory maximums. At June 30, 2019 , the Bank’s largest aggregate outstanding balance of loans to one borrower was $94.1 million of secured credit. Credit Quality and Credit Risk Management The Company’s credit quality and credit risk are controlled in two distinct areas. The first is the loan origination process, wherein the Bank underwrites credit quality and chooses which risks it is willing to accept. The second is in the ongoing oversight of the loan portfolio, where existing credit risk is measured and monitored, and where performance issues are dealt with in a timely and comprehensive fashion. The Company maintains a comprehensive credit policy, which sets forth maximum tolerances for key elements of loan risk. The policy identifies and sets forth specific guidelines for analyzing each of the loan products the Company offers from both an individual and portfolio-wide basis. The credit policy is reviewed annually by the Bank’s Board. The Bank’s underwriters ensure key risk factors are analyzed with nearly all underwriting including a comprehensive global cash flow analysis of the prospective borrowers. Credit risk is managed within the loan portfolio by the Company’s portfolio managers based on a comprehensive credit and portfolio review policy. This policy requires a program of financial data collection and analysis, comprehensive loan reviews, property and/or business inspections and monitoring of portfolio concentrations and trends. The portfolio managers also monitor borrowing bases under asset-based lines of credit, loan covenants, and other conditions associated with the Company’s business loans as a means to help identify potential credit risk. Individual loans, excluding the homogeneous loan portfolio, are reviewed at least every two years and in most cases, more often, including the assignment or confirmation of a risk grade. Risk grades are based on a six -grade Pass scale, along with Special Mention, Substandard, Doubtful and Loss classifications, as such classifications are defined by the regulatory agencies. The assignment of risk grades allows the Company to, among other things, identify the risk associated with each credit in the portfolio, and to provide a basis for estimating credit losses inherent in the portfolio. Risk grades are reviewed regularly with the Company’s Credit and Portfolio Review Committee, and the portfolio management and risk grading process is reviewed on an ongoing basis by an independent loan review function, as well as by regulatory agencies during scheduled examinations. The following provides brief definitions for risk grades assigned to loans in the portfolio: • Pass classifications represent assets with a level of credit quality, in which no well-defined deficiency or weakness exists. • Special Mention assets do not currently expose the Bank to a sufficient risk to warrant classification in one of the adverse categories, but possess correctable deficiencies or potential weaknesses deserving management’s close attention. • Substandard assets are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. These assets are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. OREO acquired from foreclosure is also classified as Substandard. • Doubtful credits have all the weaknesses inherent in Substandard credits, 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. • Loss assets are those that are considered uncollectible and of such little value that their continuance as assets is not warranted. Amounts classified as loss are promptly charged off. The Bank’s portfolio managers also manage loan performance risks, collections, workouts, bankruptcies and foreclosures. A special department, whose portfolio managers have professional expertise in these areas, typically handles or advises on these types of matters. Loan performance risks are mitigated by our portfolio managers acting promptly and assertively to address problem credits when they are identified. Collection efforts commence immediately upon non-payment, and the portfolio managers seek to promptly determine the appropriate steps to minimize the Company’s risk of loss. When foreclosure will maximize the Company’s recovery for a non-performing loan, the portfolio managers will take appropriate action to initiate the foreclosure process. When a loan is graded as Special Mention, Substandard or Doubtful, the Company obtains an updated valuation of the underlying collateral. If the credit in question is also identified as impaired, a valuation allowance, if necessary, is established against such loan or a loss is recognized by a charge to the allowance for loan losses (“ALLL”) if management believes that some or all of the full amount of the Company’s recorded investment in the loan is no longer collectable. The Company typically obtains or confirms updated valuations of underlying collateral for Special Mention and classified loans on an annual basis in order to have the most current indication of fair value. Once a loan is identified as impaired, an analysis of the underlying collateral is performed at least quarterly, and corresponding changes in any related valuation allowance are made or balances deemed to be fully uncollectable are charged-off. The following tables stratify the loan portfolio, including loans held for sale, by the Company’s internal risk grading as of the periods indicated: Credit Risk Grades Pass Special Mention Substandard Doubtful Total Gross Loans June 30, 2019 (dollars in thousands) Business loans Commercial and industrial $ 1,287,607 $ 5,150 $ 7,326 $ — $ 1,300,083 Franchise 845,659 13,630 1,010 — 860,299 Commercial owner occupied 1,659,772 953 7,187 — 1,667,912 SBA 179,488 1,131 6,911 — 187,530 Agribusiness 112,796 765 13,296 — 126,857 Real estate loans Commercial non-owner occupied 2,122,431 — 243 — 2,122,674 Multi-family 1,515,897 4,019 219 — 1,520,135 One-to-four family 247,539 — 853 — 248,392 Construction 505,401 — — — 505,401 Farmland 163,687 5,923 114 — 169,724 Land 40,110 — 638 — 40,748 Consumer loans Consumer loans 40,623 — 57 — 40,680 Totals $ 8,721,010 $ 31,571 $ 37,854 $ — $ 8,790,435 Credit Risk Grades Pass Special Substandard Doubtful Total Gross December 31, 2018 (dollars in thousands) Business loans Commercial and industrial $ 1,340,322 $ 12,005 $ 12,134 $ — $ 1,364,461 Franchise 760,795 4,431 190 — 765,416 Commercial owner occupied 1,660,994 1,580 16,548 — 1,679,122 SBA 189,006 2,289 6,906 — 198,201 Agribusiness 125,355 — 13,164 — 138,519 Real estate loans Commercial non-owner occupied 1,998,118 731 5,687 — 2,004,536 Multi-family 1,530,567 4,060 662 — 1,535,289 One-to-four family 350,083 728 5,453 — 356,264 Construction 523,643 — — — 523,643 Farmland 150,381 — 121 — 150,502 Land 46,008 132 488 — 46,628 Consumer loans Consumer loans 89,321 — 103 — 89,424 Totals $ 8,764,593 $ 25,956 $ 61,456 $ — $ 8,852,005 The following tables set forth delinquencies in the Company’s loan portfolio, including loans held for sale, at the dates indicated: Days Past Due Current 30-59 60-89 90+ Total Gross Loans Non-accruing June 30, 2019 (dollars in thousands) Business loans Commercial and industrial $ 1,293,042 $ 1,841 $ 416 $ 4,784 $ 1,300,083 $ 2,935 Franchise 859,289 — 313 697 860,299 697 Commercial owner occupied 1,666,135 1,054 — 723 1,667,912 564 SBA 184,613 511 72 2,334 187,530 2,338 Agribusiness 126,857 — — — 126,857 — Real estate loans Commercial non-owner occupied 2,122,431 — — 243 2,122,674 243 Multi-family 1,520,135 — — — 1,520,135 — One-to-four family 248,392 — — — 248,392 380 Construction 505,401 — — — 505,401 — Farmland 169,724 — — — 169,724 — Land 40,268 — — 480 40,748 480 Consumer loans Consumer loans 40,670 10 — — 40,680 — Totals $ 8,776,957 $ 3,416 $ 801 $ 9,261 $ 8,790,435 $ 7,637 Days Past Due Current 30-59 60-89 90+ Total Gross Loans Non-accruing December 31, 2018 (dollars in thousands) Business loans Commercial and industrial $ 1,362,017 $ 309 $ 1,204 $ 931 $ 1,364,461 $ 931 Franchise 759,546 5,680 — 190 765,416 190 Commercial owner occupied 1,677,967 343 — 812 1,679,122 599 SBA 195,051 524 — 2,626 198,201 2,739 Agribusiness 138,519 — — — 138,519 — Real estate loans Commercial non-owner occupied 2,004,536 — — — 2,004,536 — Multi-family 1,535,275 14 — — 1,535,289 — One-to-four family 356,219 30 9 6 356,264 398 Construction 523,643 — — — 523,643 — Farmland 150,502 — — — 150,502 — Land 46,628 — — — 46,628 — Consumer loans Consumer loans 89,249 146 29 — 89,424 — Totals $ 8,839,152 $ 7,046 $ 1,242 $ 4,565 $ 8,852,005 $ 4,857 Impaired Loans The Company considers a loan to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement or it is determined that the likelihood of the Company receiving all scheduled payments, including interest, when due is remote. The Company has no commitments to lend additional funds to debtors whose loans have been impaired. The Company reviews loans for impairment when the loan is classified as Substandard or worse, delinquent 90 days, determined by management to be collateral dependent, or when the borrower files bankruptcy or is granted a troubled debt restructuring (“TDR”). Measurement of impairment is based on the loan’s expected future cash flows discounted at the loan’s effective interest rate, measured by reference to an observable market value, if one exists, or the fair value of the collateral if the loan is deemed collateral dependent. Loans are generally charged-off at the time the loan is classified as a loss. Valuation allowances are determined on a loan-by-loan basis or by aggregating loans with similar risk characteristics.

Payments received on nonaccrual loans are generally applied as a reduction to the loan principal balance. If the likelihood of further loss is remote, the Company will recognize interest on a cash basis only. Loans may be returned to accruing status if the Company believes that all remaining principal and interest is fully collectible and there has been at least three months of sustained repayment performance since the loan was placed on nonaccrual. The Company typically does not accrue interest on loans 90 days or more past due or when, in the opinion of management, there is reasonable doubt as to the timely collection of principal or interest. The Company had impaired loans on nonaccrual status of $7.6 million at June 30, 2019 and $4.9 million at December 31, 2018 . The Company had $3.6 million in loans 90 days or more past due and still accruing at June 30, 2019 , comprised of a commercial and industrial loan for $3.4 million and a purchased credit impaired (“PCI”) loan for $159,000 . Income recognition for PCI loans is accounted for in accordance with ASC Subtopic 310-30 Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality. The Company had $213,000 in loans 90 days or more past due and still accruing at December 31, 2018 , all of which were PCI loans. There were no TDRs at June 30, 2019 and December 31, 2018 . The Company had no consumer mortgage loans collateralized by residential real estate property for which formal foreclosure proceedings were in process as of June 30, 2019 and December 31, 2018 . Purchased Credit Impaired Loans The Company has purchased loans that have experienced deterioration of credit quality between origination and acquisition and for which it was probable, at acquisition, that not all contractually required payments would be collected. The carrying amount of those loans is as follows: June 30, 2019 December 31, 2018 (dollars in thousands) Business loans Commercial and industrial $ — $ 10 Commercial owner occupied 578 632 SBA 1,190 1,265 Real estate loans Commercial non-owner occupied — 275 Total purchased credit impaired $ 1,768 $ 2,182 On each acquisition date, the amount by which the undiscounted expected cash flows of the purchased credit impaired loans exceed the estimated fair value of the loan is the “accretable yield.” The accretable yield is measured at each financial reporting date and represents the difference between the remaining undiscounted expected cash flows and the current carrying value of the purchased credit impaired loan. At June 30, 2019 , the Company had $1.8 million of purchased credit impaired loans, of which none were placed on nonaccrual status. The following table summarizes the accretable yield on the purchased credit impaired loans for the periods indicated.

Provision for Loan and Lease Losses [Abstract]
Allowance for Loan Losses	Allowance for Loan Losses The Company’s ALLL covers estimated credit losses on individually evaluated loans that are determined to be impaired as well as estimated probable incurred losses inherent in the remainder of the loan portfolio. The ALLL is prepared using the information provided by the Company’s credit review process together with data from peer institutions and economic information gathered from published sources. The loan portfolio is segmented into groups of loans with similar risk characteristics. Each segment possesses varying degrees of risk based on, among other things, the type of loan, the type of collateral, and the sensitivity of the borrower or industry to changes in external factors such as economic conditions. An estimated loss rate calculated using the Company’s actual historical loss rates adjusted for current portfolio trends, economic conditions and other relevant internal and external factors, is applied to each group’s aggregate loan balances. The Company’s base ALLL factors are determined by management using the Bank’s annualized actual trailing charge-off data over a full credit cycle with the loss emergence period extending from 1 year to 1.6 years during the first quarter of 2019. Adjustments to those base factors are made for relevant internal and external factors. Those factors may include: • Changes in national, regional and local economic conditions, including trends in real estate values and the interest rate environment, • Changes in the nature and volume of the loan portfolio, including new types of lending, • Changes in volume and severity of past due loans, the volume of nonaccrual loans and the volume and severity of adversely classified or graded loans and • The existence and effect of concentrations of credit, and changes in the level of such concentrations. For loans risk graded as watch or worse, progressively higher potential loss factors are applied based on a migration analysis of risk grading and net charge-offs. The following tables summarize the allocation of the ALLL as well as the activity in the ALLL attributed to various segments in the loan portfolio as of and for the periods indicated: Three Months

Debt Disclosure [Abstract]
Subordinated Debentures	Subordinated Debentures In August 2014, the Corporation issued $60 million in aggregate principal amount of 5.75% Subordinated Notes Due 2024 (the “Notes I”) in a private placement transaction to institutional accredited investors (the “Private Placement”). The Corporation contributed $50 million of net proceeds from the Private Placement to the Bank to support general corporate purposes. The Notes I bear interest at an annual fixed rate of 5.75% , with the first interest payment on the Notes occurring on March 3, 2015, and interest to be paid semiannually each March 3rd and September 3rd until September 3, 2024. At June 30, 2019 , the carrying value of the Notes I was $59.4 million , net of unamortized debt issuance cost of $628,000 . As of June 30, 2019 , the Notes I qualify as Tier 2 Capital. Principal and interest are due upon early redemption. In connection with the Private Placement, the Corporation obtained ratings from Kroll Bond Rating Agency (“KBRA”). KBRA assigned investment grade ratings of BBB+ and BBB for the Corporation’s senior unsecured debt and subordinated debt, respectively, and a senior deposit rating of A- for the Bank. KBRA reaffirmed these ratings in April 2019. In March 2004, the Corporation issued $10.3 million of Floating Rate Junior Subordinated Deferrable Interest Debentures (the “Subordinated Debentures”) to PPBI Trust I, statutory trust created under the laws of the State of Delaware. The Debt Securities are subordinated to effectively all borrowings of the Corporation and are due and payable on April 6, 2034. Interest is payable quarterly on the Subordinated Debentures at three-month LIBOR plus 2.75% per annum, for an effective rate of 5.35% per annum, as of June 30, 2019 . The Subordinated Debentures may be redeemed, in part or whole, on or after April 7, 2009 at the option of the Corporation, at par. The Subordinated Debentures can also be redeemed at par if certain events occur that impact the tax treatment or the capital treatment of the issuance. The Corporation also purchased a 3% minority interest totaling $310,000 in PPBI Trust I. The balance of equity of PPBI Trust I is comprised of mandatorily redeemable securities (“Trust Preferred Securities”) and is included in the Corporation’s other assets category. PPBI Trust I sold $10.0 million of Trust Preferred Securities to investors in a private offering. On April 1, 2017, as part of the HEOP acquisition, the Corporation assumed $5.2 million of floating rate junior subordinated debt securities associated with Heritage Oaks Capital Trust II. Interest is payable quarterly at three-month LIBOR plus 1.72% per annum, for an effective rate of 4.31% per annum as of June 30, 2019 . At June 30, 2019 , the carrying value of these debentures was $4.0 million , which reflects purchase accounting fair value adjustments of $1.2 million . The Corporation also assumed $3.1 million and $5.2 million of floating rate junior subordinated debt associated with Mission Community Capital Trust I and Santa Lucia Bancorp (CA) Capital Trust, respectively. At June 30, 2019 , the carrying value of Mission Community Capital Trust I and Santa Lucia Bancorp (CA) Capital Trust were $2.8 million and $3.9 million , respectively, which reflects purchase accounting fair value adjustments of $296,000 and $1.3 million , respectively. Interest is payable quarterly at three-month LIBOR plus 2.95% per annum, for an effective rate of 5.55% per annum as of June 30, 2019 for Mission Community Capital Trust I. Interest is payable quarterly at three-month LIBOR plus 1.48% per annum, for an effective rate of 4.08% per annum as of June 30, 2019 for Santa Lucia Bancorp (CA) Capital Trust. These three debentures are callable by the Corporation at par. On November 1, 2017, as part of the Plaza acquisition, the Corporation assumed three subordinated notes totaling $25.0 million at a fixed interest rate of 7.125% payable in arrears on a quarterly basis. The notes have a maturity date of June 26, 2025 and are also redeemable in whole or in part beginning on June 26, 2020 at an amount equal to 103.0% of principal plus accrued unpaid interest. The redemption price decreases 50 basis points each subsequent year. At June 30, 2019 , the carrying value of these subordinated notes was $25.1 million , which reflects purchase accounting fair value adjustments of $145,000 . On July 1, 2018, as part of the Grandpoint acquisition, the Corporation assumed $5.2 million of floating rate junior subordinated debt securities associated with First Commerce Bancorp Statutory Trust I. Interest is payable quarterly at three-month LIBOR plus 2.95% per annum, for an effective rate of 5.54% per annum as of June 30, 2019 . At June 30, 2019 , the carrying value of these debentures was $4.9 million , which reflects purchase accounting fair value adjustments of $217,000 . The Corporation is not allowed to consolidate any trust preferred securities into the Company’s consolidated financial statements. The resulting effect on the Company’s consolidated financial statements is to report only the subordinated debentures relating to trust preferred securities as a component of the Company’s liabilities. In May 2019, the Corporation issued $125 million in aggregate principal amount of 4.875% Fixed-to-Floating Rate Subordinated Notes due May 15, 2029 (the “Notes II”), at a public offering price equal to 100% of the aggregate principal amount of the Notes II. The Company may redeem the Notes II on or after May 15, 2024. From and including the issue date, but excluding May 15, 2024, the Notes II will bear interest at an initial fixed rate of 4.875% per annum, payable semi-annually. From and including May 15, 2024 to, but excluding the maturity date or the date of earlier redemption, the Notes II will bear interest at a floating rate equal to the then-current three-month LIBOR rate determined on the determination date of the applicable interest period, plus a spread of 2.50% ; provided, however, in the event that the then-current three-month LIBOR is less than zero, then the three-month LIBOR will be deemed to be zero. At June 30, 2019 , the carrying value of the Notes II was $122.5 million , net of unamortized debt issuance cost of $2.5 million . At June 30, 2019, the Notes II qualify as Tier 2 Capital. Principal and interest are due upon early redemption at any time, including prior to May 15, 2024 at our option, in whole but not in part, under the occurrence of special events defined within the trust indenture.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share In February 2019, the Company’s Compensation Committee of Board of Directors reviewed the various forms of outstanding equity awards, including restricted stock and restrict stock units, and approved that unvested restricted stock awards will be considered participating securities. As a result of the different treatment of unvested restricted stock and unvested RSUs, beginning in 2019, earnings per common share is computed using the two-class method. Under the two-class method, distributed and undistributed earnings allocable to participating securities are deducted from net income to determine net income allocable to common shareholders, which is then used in the numerator of both basic and diluted earnings per share calculations. Basic earnings per common share are computed by dividing net income allocable to common shareholders by the weighted average number of common shares outstanding for the reporting period, excluding outstanding participating securities. Diluted earnings per common share are computed by dividing net income allocable to common shareholders by the weighted average number of common shares outstanding over the reporting period, adjusted to include the effect of potentially dilutive common shares, but excludes awards considered participating securities. The computation of diluted earnings per common share excludes the impact of the assumed exercise or issuance of securities that would have an anti-dilutive effect. The following tables set forth the Company’s earnings per share calculations for the periods indicated: Three Months Ended June 30, 2019 March 31, 2019 June 30, 2018 (dollars in thousands, except per share data) Basic Net income $ 38,527 $ 38,718 $ 27,303 Less: Earnings allocated to participating securities (444 ) (347 ) — Net income allocated to common stockholders 38,083 38,371 27,303 Weighted average common shares outstanding 61,308,046 61,987,605 46,053,077 Basic earnings per common share $ 0.62 $ 0.62 $ 0.59 Diluted Net income allocated to common stockholders $ 38,083 $ 38,371 $ 27,303 Weighted average common shares outstanding 61,308,046 61,987,605 46,053,077 Diluted effect of share-based compensation 353,727 298,178 649,891 Weighted average diluted common shares 61,661,773 62,285,783 46,702,968 Diluted earnings per common share $ 0.62 $ 0.62 $ 0.58 Six Months Ended June 30, 2019 June 30, 2018 (dollars in thousands, except per share data) Basic Net income $ 77,245 $ 55,305 Less: Earnings allocated to participating securities (791 ) — Net income allocated to common stockholders 76,454 55,305 Weighted average common shares outstanding 61,645,940 45,973,727 Basic earnings per common share $ 1.24 $ 1.20 Diluted Net income allocated to common stockholders $ 76,454 $ 55,305 Weighted average common shares outstanding 61,645,940 45,973,727 Diluted effect of share-based compensation 334,193 704,396 Weighted average diluted common shares 61,980,133 46,678,123 Diluted earnings per common share $ 1.23 $ 1.18 For the three and six months ended June 30, 2019 , there were no RSUs or stock options that were anti-dilutive.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value of an asset or liability is the exchange price that would be received to sell that asset or paid to transfer that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach, and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including both those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis and a non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value are discussed below. In accordance with accounting guidance, the Company groups its financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described as follows: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, prepayment speeds, volatilities, etc.) or model-based valuation techniques where all significant assumptions are observable, either directly or indirectly, in the market. Level 3 - Valuation is generated from model-based techniques where one or more significant inputs are not observable, either directly or indirectly, in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques may include use of matrix pricing, discounted cash flow models, and similar techniques. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature, and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the fair values presented. Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent limitations in any estimation technique. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management maximizes the use of observable inputs and attempts to minimize the use of unobservable inputs when determining fair value measurements. Estimated fair values are disclosed for financial instruments for which it is practicable to estimate fair value. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following is a description of both the general and specific valuation methodologies used to measure financial assets and liabilities on a recurring basis, as well as the general classification of these instruments pursuant to the fair value hierarchy. Investment securities – Investment securities are generally valued based upon quotes obtained from independent third-party pricing services, which uses evaluated pricing applications and model processes. Observable market inputs, such as, benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data are considered as part of the evaluation. The inputs are related directly to the security being evaluated, or indirectly to a similarly situated security. Market assumptions and market data are utilized in the valuation models. The Company reviews the market prices provided by the third-party pricing service for reasonableness based on the Company’s understanding of the market place and credit issues related to the securities. The Company has not made any adjustments to the market quotes provided by them and, accordingly, the Company categorized its investment portfolio within Level 2 of the fair value hierarchy. Derivative assets and liabilities – The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a market standard discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps is classified as Level 2. The following fair value hierarchy table presents information about the Company’s financial assets and liabilities measured at fair value on a recurring basis at the dates indicated: June 30, 2019 Fair Value Measurement Using Level 1 Level 2 Level 3 Total Fair Value (dollars in thousands) Financial assets Investment securities available-for-sale: U.S. Treasury $ — $ 63,552 $ — $ 63,552 Agency — 199,233 — 199,233 Corporate — 124,119 — 124,119 Municipal bonds — 288,406 — 288,406 Collateralized mortgage obligation — 19,236 — 19,236 Mortgage-backed securities — 563,833 — 563,833 Total securities available-for-sale $ — $ 1,258,379 $ — $ 1,258,379 Derivative assets $ — $ 153 $ — $ 153 Financial liabilities Derivative liabilities $ — $ 153 $ — $ 153 December 31, 2018 Fair Value Measurement Using Level 1 Level 2 Level 3 Total Fair Value (dollars in thousands) Financial assets Investment securities available-for-sale: U.S. Treasury $ — $ 60,912 $ — $ 60,912 Agency — 130,070 — 130,070 Corporate — 103,543 — 103,543 Municipal bonds — 238,630 — 238,630 Collateralized mortgage obligation — 24,338 — 24,338 Mortgage-backed securities — 545,729 — 545,729 Total securities available-for-sale $ — $ 1,103,222 $ — $ 1,103,222 Derivative assets $ — $ 1,681 $ — $ 1,681 Financial liabilities Derivative liabilities $ — $ 1,681 $ — $ 1,681 Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Impaired Loans and Other Real Estate Owned – A loan is considered impaired when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Impairment is measured based on the fair value of the underlying collateral or the discounted expected future cash flows. The Company measures impairment on all nonaccrual loans for which it has reduced the principal balance to the value of the underlying collateral less the anticipated selling cost. OREO are recorded at estimated fair value less the costs to sell at the time of foreclosure or at the lower of cost or estimated fair value less the costs to sell subsequent to acquisition. The fair value of impaired loans and other real estate owned were determined using Level 3 assumptions, and represents impaired loan and other real estate owned balances for which a specific reserve has been established or on which a write down has been taken. Generally, the Company obtains third party appraisals (or property valuations) and/or collateral audits in conjunction with internal analysis based on historical experience on its impaired loans and other real estate owned to determine fair value. In determining the net realizable value of the underlying collateral for impaired loans, the Company will then discount the valuation to cover both market price fluctuations and selling costs the Company expected would be incurred in the event of foreclosure. In addition to the discounts taken, the Company’s calculation of net realizable value considered any other senior liens in place on the underlying collateral. At June 30, 2019 and December 31, 2018, substantially all the Company’s impaired loans were evaluated based on the fair value of their underlying collateral based upon the most recent appraisal available to management. The Company completed partial charge-offs on certain impaired loans individually evaluated for impairment based on recent real estate appraisals and released the related specific reserves during the six months ended June 30, 2019 . The Company has recorded no specific reserve on loans deemed impaired at June 30, 2019 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments From time to time, the Company enters into interest rate swap agreements with certain borrowers to assist them in mitigating their interest rate risk exposure associated with the loans they have with the Company. At the same time, the Company enters into identical interest rate swap agreements with another financial institution to mitigate the Company’s interest rate risk exposure associated with the swap agreements it enters into with its borrowers. The Company had swaps with matched terms with an aggregate notional amount of $56.6 million and a fair value of $153,000 at June 30, 2019 compared with an aggregate notional amount of $57.5 million and a fair value of $1.7 million at December 31, 2018 . The fair value of these agreements are determined through a third party valuation model used by the Company’s counterparty bank, which uses observable market data such as cash LIBOR rates, prices of Eurodollar future contracts and market swap rates. The fair values of these swaps are recorded as components of other assets and other liabilities in the Company’s condensed consolidated balance sheet. Changes in the fair value of these swaps, which occur due to changes in interest rates, are recorded in the Company’s income statement as a component of noninterest income. Since the terms of the swap agreements between the Company and its borrowers have been matched with the terms of swap agreements with another financial institution, the adjustments for the change in their fair value offset each other in noninterest income. Although changes in the fair value of swap agreements between the Company and borrowers and the Company and other financial institutions offset each other, changes in the credit risk of these counterparties may result in a difference in the fair value of these swap agreements. Offsetting swap agreements the Company has with other financial institutions are collateralized with cash, and swap agreements with borrowers are secured by the collateral arrangements for the underlying loans these borrowers have with the Company. During the six months ended June 30, 2019 and 2018 , there were no losses recorded on swap agreements attributable to the change in credit risk associated with a counterparty. All interest rate swap agreements entered into by the Company as of June 30, 2019 and December 31, 2018 are not designated as hedging instruments.

Offsetting [Abstract]
Balance Sheet Offsetting	Balance Sheet Offsetting Derivative financial instruments may be eligible for offset in the consolidated balance sheets, such as those subject to enforceable master netting arrangements or a similar agreement. Under these agreements, the Company has the right to net settle multiple contracts with the same counterparty. The Company offers an interest rate swap product to qualified customers, which are then paired with derivative contracts the Company enters into with a counterparty bank. While derivative contracts entered into with counterparty banks may be subject to enforceable master netting agreements, derivative contracts with customers may not be subject to enforceable master netting arrangements.

Leases [Abstract]
Leases	Leases The Company accounts for its leases in accordance with ASC 842, which was implemented on January 1, 2019, and requires the Company to record liabilities for future lease obligations as well as assets representing the right to use the underlying leased asset. The Company’s leases primarily represent future obligations to make payments for the use of buildings or space for its operations. Liabilities to make future lease payments are recorded in Accrued expenses and other liabilities, while right-of-use assets are recorded in Other assets in the Company’s consolidated balance sheets. At June 30, 2019 , all of the Company’s leases were classified as either operating leases or short-term leases. Liabilities to make future lease payments and right of use assets are recorded for operating leases and not short-term leases. These liabilities and right-of-use assets are determined based on the total contractual base rents for each lease, which include options to extend or renew each lease, where applicable, and where the Company believes it has an economic incentive to extend or renew the lease. Future contractual base rents are discounted using the rate implicit in the lease or using the Company’s estimated incremental borrowing rate if the rate implicit in the lease is not readily determinable. For leases that contain variable lease payments, the Company assumes future lease payment escalations based on a lease payment escalation rate specified in the lease or the specified index rate observed at the time of lease commencement. Liabilities to make future lease payments are accounted for using the interest method, being reduced by periodic contractual lease payments net of periodic interest accretion. Right-of-use assets for operating leases are amortized over the term of the associated lease by amounts that represent the difference between periodic straight-line lease expense and periodic interest accretion in the related liability to make future lease payments. For the three and six months ended June 30, 2019 , expense associated with the Company’s leases totaled $3.4 million and $6.8 million , respectively, and was recorded in premises and occupancy expense in the consolidated statements of income. For the three and six ended June 30, 2019 , expense attributed to operating leases totaled approximately $2.8 million and $5.5 million , respectively. Expense attributed to short-term leases for the three and six ended June 30, 2019 totaled approximately $627,000 and $1.3 million , respectively. Short-term leases are leases that have a term of 12 months or less at commencement. The following table presents supplemental information related to operating leases as of the period indicated: June 30, 2019 (dollars in thousands) Balance Sheet: Operating lease right of use assets $ 43,504 Operating lease liabilities 46,124 Cash Flows: Operating cash flows from operating leases 5,957 The following table provides information related to minimum contractual lease payments and other information associated with the Company’s leases as of June 30, 2019 : 2019 2020 2021 2022 2023 Thereafter Total (dollars in thousands) Contractual base rents (1) : Operating leases $ 5,348 $ 9,169 $ 9,585 $ 9,134 $ 8,150 $ 13,485 $ 54,871 Short-term leases 610 109 — — — — 719 Total contractual base rents $ 5,958 $ 9,278 $ 9,585 $ 9,134 $ 8,150 $ 13,485 $ 55,590 Total liability to make lease payments $ 46,124 Difference in undiscounted and discounted future lease payments $ 9,464 Weighted average discount rate 6.29 % Weighted average remaining lease term (years) 5.9 (1) Contractual base rents reflect options to extend and renewals, and do not include property taxes and other operating expenses due under respective lease agreements.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company earns revenue from a variety of sources. The Company’s principal source of revenue is interest income on loans, investment securities and other interest earning assets, while the remainder of the Company’s revenue is earned from a variety of fees, service charges, gains and losses, and other income, all of which are classified as noninterest income. Revenue from interest on loans and investment securities is accounted for on an accrual basis using the interest method, while revenue from other sources is accounted for under other applicable U.S. GAAP as well as ASC 606 - Revenue from Contracts with Customers . Revenue streams within the scope of and accounted for under ASC 606 include: service charges and fees on deposit accounts, debit card interchange fees, fees from other services the Company provides its customers and gains and losses from the sale of other real estate owned and property, premises and equipment. ASC 606 requires revenue to be recognized when the Company satisfies the related performance obligations by transferring to the customer a good or service. The recognition of revenue under ASC 606 requires the Company to first identify the contract with the customer, identify the associated performance obligations, determine the transaction price, allocate the transaction price to the performance obligations and finally recognize revenue when the performance obligations have been satisfied and the good or service has been transferred. The majority of the Company’s contracts with customers associated with revenue streams that are within the scope of ASC 606 are considered short-term in nature, can be canceled at any time by the customer or the Company without penalty, such as a deposit account agreement, and are satisfied at a point in time. These revenue streams are included in non-interest income. The following tables provide a summary of the Company’s revenue streams, including those that are within the scope of ASC 606 and those that are accounted for under other applicable U.S. GAAP: Three Months Ended June 30, 2019 March 31, 2019 June 30, 2018 Within Scope (1) Out of Scope (2) Within Scope (1) Out of Scope (2) Within Scope (1) Out of Scope (2) (dollars in thousands) Interest income: Loans $ — $ 121,860 $ — $ 121,476 $ — $ 85,625 Investment securities and other interest-earning assets — 10,554 — 9,767 — 7,074 Total interest income — 132,414 — 131,243 — 92,699 Noninterest income: Loan servicing fees — 409 — 398 — 292 Service charges on deposit accounts 1,441 — 1,330 — 1,057 — Other service fee income 363 — 356 — 169 — Debit card interchange income 1,145 — 1,071 — 1,090 — Earnings on bank-owned life insurance — 851 — 910 — 617 Net gain from sales of loans — 902 — 1,729 — 3,843 Net gain from sales of investment securities — 212 — 427 — 330 Other income 544 457 192 1,268 293 460 Total noninterest income 3,493 2,831 2,949 4,732 2,609 5,542 Total revenues $ 3,493 $ 135,245 $ 2,949 $ 135,975 $ 2,609 $ 98,241 (1) Revenues from contracts with customers accounted for under ASC 606.

(2) Revenues not within the scope of ASC 606 and accounted for under other applicable U.S. GAAP requirements. The following provides information concerning the major components of the Company’s revenue: Interest Income Interest income is comprised of interest on loans, investment securities and other interest-earning assets. Interest is recognized using the interest method, which reflects the contractual yield on loans and coupon yield for investment securities. These yields are adjusted for purchase discounts, premiums and net deferred loan origination fees/costs for newly originated loans. Loan Servicing Fees Loan servicing fees generally consist of fees related to servicing of loans for others, as well as the net impact of related serving asset amortization. ASC 606 stipulates that income streams generated through the transfer and servicing of financial instruments shall be accounted for under ASC 860 - Transfers and Servicing and is therefore excluded from the scope of ASC 606. Service Charges on Deposit Accounts and Other Service Fee Income Service charges on deposit accounts and other service fee income consists of periodic service charges on deposit accounts and transaction based fees such as those related to overdrafts, ATM charges and wire transfer fees. The majority of these revenues are accounted for under ASC 606. Performance obligations for periodic service charges on deposit accounts are typically short-term in nature and are generally satisfied on a monthly basis, while performance obligations for other transaction based fees are typically satisfied at a point in time (which may consist of only a few moments to perform the service or transaction) with no further obligations on behalf of the Company to the customer. Periodic service charges are generally collected monthly directly from the customer's deposit account, and at the end of a statement cycle, while transaction based service charges are typically collected at the time of or soon after the service is performed. Debit Card Interchange Income Debit card interchange fee income consists of transaction processing fees associated with customer debit card transactions processed through a payment network and are accounted for under ASC 606. These fees are earned each time a request for payment is originated by a customer debit cardholder at a merchant. In these transactions, the Company transfers funds from the debit cardholder’s account to a merchant through a payment network at the request of the debit cardholder by way of the debit card transaction. The related performance obligations are generally satisfied when the transfer of funds is complete, which is generally a point in time when the debit card transaction is processed. Debit card interchange fees are typically received and recorded as revenue on a daily basis. Earnings on Bank-Owned Life Insurance Earnings on bank-owned life insurance relates to the periodic increase in the cash surrender value of bank-owned life insurance policies on certain key employees of the Company for which the Company is the owner and beneficiary of the related policies. This revenue stream is excluded from the scope of ASC 606, and is accounted for under other applicable U.S. GAAP provisions (ASC 325-30). Gains and (Losses) from Sales of Loans and Investment Securities ASC 606 stipulates that gains and (losses) from the periodic sale of loans and investment securities are excluded from ASC 606 and are accounted for under other applicable U.S. GAAP provisions. Other Income Other income generally consists of recoveries on acquired loans, which were fully charged off and had no book value prior to their acquisition. This revenue stream is excluded from the scope of ASC 606 and is accounted for under other applicable U.S. GAAP provisions. Other income also consists of other miscellaneous fees, which are accounted for under ASC 606; however, much like service charges on deposit accounts, these fees have performance obligations that are very short-term in nature and are typically satisfied at a point in time. Revenue is typically recorded at the time these fees are collected, which is generally upon the completion the related transaction or service provided. Other revenue streams that may be applicable to the Company include gains and losses from the sale of non-financial assets such as other real estate owned and property premises and equipment. The Company accounts for these revenue streams in accordance with ASC 610-20, which requires the Company to look to guidance in ASC 606 in the application of certain measurement and recognition concepts. The Company records gains and losses on the sale of non-financial assets when control of the asset has been surrendered to the buyer, which generally occurs at a specific point in time. Practical Expedient The Company also employs a practical expedient with respect to contract acquisition costs, which are generally capitalized and amortized into expense. These costs relate to expenses incurred directly attributable to the efforts to obtain a contract. The practical expedient allows the Company to immediately recognize contract acquisition costs in current period earnings when these costs would have been amortized over a period of one year or less. At June 30, 2019 , the Company did not have any material contract assets or liabilities in its consolidated financial statements related to revenue streams within the scope of ASC 606, and there were no material changes in those balances during the reporting period.

Accounting Policies [Abstract]
Recently Issued Accounting Pronouncements	Accounting Standards Adopted in 2019 In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchase Callable Debt Securities . This Update amends guidance on the amortization period of premiums on certain purchased callable debt securities. The amendments shorten the amortization period of premiums on purchased callable debt securities to the earliest call date. This Update should be applied on a modified retrospective basis through a cumulative-effect adjustment to beginning retained earnings. The effective date of ASU 2017-08 is for interim and annual reporting periods beginning after December 15, 2018. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , ASU 2018-11, Leases (Topic 842): Targeted Improvements , ASU 2018-10, Codification Improvements to Topic 842, Leases . This Update is being issued to increase the transparency and comparability around lease obligations. Previously unrecorded off-balance sheet obligations and corresponding rights to use underlying leased assets will now be recorded in the consolidated financial statements, accompanied by enhanced qualitative and quantitative disclosures in the notes to the consolidated financial statements. The Update is generally effective for public business entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842): Targeted Improvements . ASU 2018-10 provides improvements related to ASU 2016-02 to increase stakeholders’ awareness of the amendments to Topic 842 and to expedite the improvements. The amendments affect narrow aspects of the guidance issued in ASU 2016-02. ASU 2018-11 allows entities adopting ASU 2016-02 to choose an additional transition method, under which an entity initially applies the accounting guidance for leases under Topic 842 at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, ASU 2018-11 allows an entity electing this additional transition method to continue to present comparative period financial statements in accordance with Topic 840 (current U.S. GAAP). ASU 2018-11 also allows lessors to not separate non-lease components from the associated lease component if certain conditions are met. The amendments in these updates became effective for annual periods as well as interim periods within those annual periods beginning after December 15, 2018. The Company elected to apply the transition provisions of Topic 842 using the alternative transition method whereby comparative periods are not restated. The Company also elected to adopt the “package” of practical expedients in its transition to Topic 842, as specified in Accounting Standard Codification (“ASC”) 842-10-65. The results of this policy election are that the Company reflected the provisions of Topic 842 in its consolidated financial statements for the first time as of and for the period ended March 31, 2019 (the period of adoption). The Company measured and recorded liabilities to make lease payments as well as right-of-use assets in the period of adoption for leases that existed as of the transition date, and will continue to present all comparative periods under Topic 840. Under this elected transition method, the Company is not required to reassess the following as part of its transition to Topic 842: (1) whether any expired or existing contracts contain leases, (2) lease classifications for any existing or expired leases and (3) initial direct costs for any existing leases. Additionally, the Company elected to apply the use of hindsight in its assessment of the term for its leases upon transition, which allows for consideration of the Company’s option to extend or terminate a lease. The Company adopted the provisions of Topic 842 on January 1, 2019, and in its transition to Topic 842, the Company initially recorded a liability to make future lease payments of approximately $45.7 million and right-of-use assets of approximately $43.8 million . The difference of $1.9 million is the accounting adjustments previously recorded under Topic 840 and Topic 805, as required by transition guidance in ASC 842-10-65. The Company was not required to record a cumulative effect adjustment to the opening balance of retained earnings as part of its transition to Topic 842. The Company’s evaluation of lease obligations and service agreements under the new standard included an assessment of the appropriate classification and related accounting of each lease agreement, a review of applicability of the new standard to existing service agreements and gathering all essential lease data to facilitate the application of the new standard. The Company’s review indicated that all of its leases are classified as operating leases or short-term leases. In accordance with the provisions of Topic 842, liabilities to make future lease payments and right-of-use assets are only recorded for leases that are not considered short-term (leases with an original term of greater than 12 months). The Company records expense for its leases on a straight-line basis in accordance with the requirements under Topic 842 for operating leases. The Company’s expense recognition for its operating leases (including short-term leases) under Topic 842 has not differed significantly from that recorded under Topic 840. Right-of-use assets for operating leases are amortized over the lease term and liabilities to make future lease payments are accounted for using the interest method, both in accordance with Topic 842. Please also refer to Note 13 - Leases for additional information related to the Company’s leases. Recent Accounting Guidance Not Yet Effective In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments . This Update was issued as part of an ongoing project on the FASB’s agenda for improving the Codification or correcting for its unintended application. The FASB issued this Update, which is specific to Updates: 2016-13, Financial Instruments- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , and 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. Improvements within this Update include: (1) Allowing the measurement of credit losses on accrued interest receivable balances to be determined separately from the other components of the amortized cost basis of associated financial assets. (2) Allow entities to make an accounting policy election to not measure credit losses on accrued interest receivable balances if the entity writes off the uncollectable accrued interest balances in a timely manner through a reversal of interest income or through the recognition of credit loss expense, or both. (3) Allow entities to make an accounting policy election to present accrued interest receivable balances and any related allowance for credit losses separately from the associated financial assets on the balance sheet (not including them as part of the associated financial asset’s amortized cost). (4) Allow entities to elect a practical expedient to disclose separately the total amount of accrued interest included in the amortized cost basis as a single balance to meet certain disclosure requirements. (5) Require that entities reverse from earnings any allowance for credit losses or valuation allowance previously measured on a loan or debt security upon the reclassification of the loan or debt security from one classification or category to another (such as from held for investment to held for sale), and apply the applicable measurement guidance with the new classification or category. (6) Clarify that an entity should include an estimate for recoveries of amounts previously written off in its estimation of the allowance for credit losses. (7) Allow entities to use future interest rate environment projections in the determination of the allowance for credit losses under the discounted cash flow method. (8) Allow an entity to make an accounting policy election to adjust the effective interest rate used to discount expected future cash flows for expected prepayments on financial assets within the scope of ASC 326-20 and on available for sale debt securities within the scope of ASC 326-30 to appropriately isolate credit risk in the determination of the allowance for credit losses. (9) Clarify that an entity should consider, when determining the contractual term of a financial asset, extension or renewal options that are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the entity. (10) Clarify the guidance by specifically requiring that an entity re-measure an equity security without readily determinable fair value at fair value when an orderly transaction is identified for an identical or similar investment of the same issuer in accordance with Topic 820. That is, the amendments clarify that the measurement alternative is a nonrecurring fair value measurement. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company is currently evaluating the effects of this Update on its financial statements and disclosures. In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842): Codification Improvements. This Update provides clarification on certain aspects of an entity’s implementation of Topic 842 including those that relate to: (1) Determining the fair value of the underlying asset by lessors that are not manufacturers or dealers. The amendments related to this item carry forward from Topic 840 to Topic 842 an exception that allows lessors who are not manufacturers or dealers to use the cost of the underlying asset as its fair value. (2) Presentation on the statement of cash flows - sales-type and direct financing leases. The amendments related to this item clarify that all principal payments received on leases by lessors in sales-type or direct financing lease transactions should be reflected in investing activities for entities such as depository and lending institutions within in the scope of Topic 942. (3) Transition disclosures related to Topic 250, Accounting Changes and Error Corrections. The amendments related to this item clarify the FASB’s original intent by explicitly providing an exception to the paragraph 250-10-50-3 interim disclosure requirements in the Topic 842 transition disclosure requirements, which would otherwise require interim disclosures after the date of adoption of Topic 842 related to the impacts of the change on: (a) income from continuing operations, (b) net income, (c) any other financial statement line item and (d) any affected per-share amounts. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted. The Company does not believe the effects of this ASU will have a material effect on the Company’s financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement . The amendments in this Update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement . The following disclosure requirements for public companies were removed from Topic 820: • The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy • The policy for timing of transfers between levels • The valuation processes for Level 3 fair value measurements The following disclosure requirements for public companies were modified in Topic 820: • The amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date The following disclosure requirements for public companies were added to Topic 820: • The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period • The range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. In addition, an entity may early adopt any of the removed or modified disclosures immediately and delay adoption of the new disclosures until the effective date. The Company is currently evaluating the effects of ASU 2018-13 on its financial statements and disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This Update replaces the incurred loss impairment model in current U.S. GAAP with a model that reflects current expected credit losses (“CECL”). The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. CECL also requires credit losses on available-for-sale debt securities be measured through an allowance for credit losses when the fair value is less than the amortized cost basis. It also applies to off-balance sheet credit exposures. The Update requires that all expected credit losses for financial assets held at the reporting date be measured based on historical experience, current conditions and reasonable and supportable forecasts. The Update also requires enhanced disclosure, including qualitative and quantitative disclosures that provide additional information about significant estimates and judgments used in estimating credit losses. For public business entities, the Update is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. In May 2019, the FASB issued ASU 2019-05, Financial Instruments-Credit Losses (Topic 326):Targeted Transition Relief, to allow companies to irrevocably elect, upon adoption of ASU 2016-13, the fair value option for financial instruments that (1) were previously recorded at amortized cost and (2) are within the scope of the credit losses guidance in ASC 326-20, (3) are eligible for the fair value option under ASC 825-10, and (4) are not held-to-maturity debt securities. Entities are required to make this election on an instrument-by-instrument basis. The effective date will be the same as the effective date in ASU 2016-13. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures, and has contracted with an industry expert to: (1) develop a new expected loss model with supportable assumptions, (2) identify data, reporting and disclosure gaps, (3) provide quantitative modeling and (4) assess, develop and document updates to accounting policies, new processes and controls. The Company’s CECL Committee and related sub-committees and working groups, made up of members of finance, credit, lending, internal audit and risk management continue with coordinated efforts around model development, which have become more focused on model refinements, including those related to software applications that drive model calculations. The Company’s CECL Committee has also begun the process of reviewing and analyzing certain elements of model output. Other workflows currently in process or scheduled to begin soon, and driven by the Company’s CECL Committee include: (1) development of model documentation, (2) model validation, (3) analysis and documentation of model data requirements, (4) identification of risk in the modeling process and assessment of existing controls and the design of new controls and (5) development of required policies, procedures and disclosures. The magnitude of the adjustment and the overall impact of the new guidance on the Company’s consolidated financial statements cannot yet be reasonably estimated.
Revenue Recognition	Revenue Recognition – The Company accounts for certain of its revenue streams in accordance with ASC 606 - Revenue from Contracts with Customers . Revenue streams within the scope of and accounted for under ASC 606 include: service charges and fees on deposit accounts, debit card interchange fees, fees from other services the Bank provides its customers and gains and losses from the sale of other real estate owned and property, premises and equipment. ASC 606 requires revenue to be recognized when the Company satisfies related performance obligations by transferring to the customer a good or service. The recognition of revenue under ASC 606 requires the Company to first identify the contract with the customer, identify the performance obligations, determine the transaction price, allocate the transaction price to the performance obligations and finally recognize revenue when the performance obligations have been satisfied and the good or service has been transferred. The majority of the Company’s contracts with customers associated with revenue streams that are within the scope of ASC 606 are considered short-term in nature and can be canceled at any time by the customer or the Bank, such as a deposit account agreement. Other more significant revenue streams for the Company such as interest income on loans and investment securities are specifically excluded from the scope of ASC 606 and are accounted for under other applicable U.S. GAAP.
Goodwill and Core Deposit Intangible	Goodwill and Core Deposit Intangible – Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exist that indicate the necessity for such impairment tests to be performed. The Company has selected the fourth quarter as the period to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Core deposit intangible assets arising from whole bank acquisitions are amortized on either an accelerated basis, reflecting the pattern in which the economic benefits of the intangible assets is consumed or otherwise used up, or on a straight-line amortization method over their estimated useful lives, which range from 6 to 10 years
Use of Estimates	Use of Estimates
Fair Value Measurement	Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Impaired Loans and Other Real Estate Owned – A loan is considered impaired when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Impairment is measured based on the fair value of the underlying collateral or the discounted expected future cash flows. The Company measures impairment on all nonaccrual loans for which it has reduced the principal balance to the value of the underlying collateral less the anticipated selling cost. OREO are recorded at estimated fair value less the costs to sell at the time of foreclosure or at the lower of cost or estimated fair value less the costs to sell subsequent to acquisition. The fair value of impaired loans and other real estate owned were determined using Level 3 assumptions, and represents impaired loan and other real estate owned balances for which a specific reserve has been established or on which a write down has been taken. Generally, the Company obtains third party appraisals (or property valuations) and/or collateral audits in conjunction with internal analysis based on historical experience on its impaired loans and other real estate owned to determine fair value. In determining the net realizable value of the underlying collateral for impaired loans, the Company will then discount the valuation to cover both market price fluctuations and selling costs the Company expected would be incurred in the event of foreclosure. In addition to the discounts taken, the Company’s calculation of net realizable value considered any other senior liens in place on the underlying collateral.
