PACIFIC PREMIER BANCORP, INC. AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2017

(UNAUDITED)

Note 1 - 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 consolidated financial statements contain all adjustments (consisting of normal recurring accruals) necessary to present fairly the Company’s financial position as of September 30, 2017 and December 31, 2016, the results of its operations and comprehensive income for the three months ended September 30, 2017, June 30, 2017 and September 30, 2016 and the nine months ended September 30, 2017 and September 30, 2016 and the changes in stockholders’ equity and cash flows for the nine months ended September 30, 2017 and 2016. Operating results or comprehensive income for the nine months ended September 30, 2017 are not necessarily indicative of the results or comprehensive income that may be expected for any other interim period or the full year ending December 31, 2017.

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, 2016 (the “2016 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, and Santa Lucia Bancorp (CA) Capital Trust, under the equity method whereby the subsidiary’s net earnings are recognized in the Company’s statement of income.

Note 2 – Recently Issued Accounting Pronouncements

Accounting Standards Adopted in 2017

In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Accounting. The amendments simplify several aspects of the accounting for share-based payment award transactions, including accounting for excess tax benefits and tax deficiencies, classifying excess tax benefits on the statement of cash flows, accounting for forfeitures, classifying awards that permit share repurchases to satisfy statutory tax-withholding requirements and classifying tax payments on behalf of employees on the statement of cash flows. For public business entities, the amendment is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is permitted for any organization in any interim or annual period. As a result of the adoption of ASU 2016-09, the Company began recognizing the tax effects of exercised or vested awards as discrete items in the reporting period in which they occur, resulting in a $355,000 and a $2.0 million tax benefit to the Company for the three and nine months ended September 30, 2017, respectively.

In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships. The amendments clarify that a change in the counterparty to a derivative instrument designated as a hedging instrument does not, in and of itself, require designation of that hedging relationship provided that all other hedge accounting criteria remain the same. The

8

Update is effective for public business entities for fiscal years beginning after December 31, 2016, including interim periods within those years. The adoption of this standard did not have a material effect on the Company's operating results or financial condition.

Recent Accounting Guidance Not Yet Effective

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. The amendments provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. Modification accounting will apply unless all of the following are the same immediately before and after the modification:

• The award’s fair value – or calculated value or intrinsic value, if an alternative method is used. If the modification does not affect any inputs to the valuation of the award, estimating the value immediately before and after the modification is not required.

• The award’s vesting provisions

• The award’s classification as an equity instrument or a liability instrument

The Update is effective for all entities for fiscal years beginning after December 15, 2017, including interim periods within those years. The amendments should be applied prospectively to awards modified on or after the effective date. The adoption of this standard will not material effect the Company's operating results or financial condition, as historically the Company has not modified share-based awards.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For public business entities, the amendment is effective for annual periods beginning after December 15, 2019 and interim period within those annual periods. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures. The Company is in the process of compiling key data elements and considering software models that will meet the requirements of the new guidance.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new standard is being issued to increase the transparency and comparability around lease obligations. Previously unrecorded off-balance sheet obligations will now be brought more prominently to light by presenting lease liabilities on the face of the balance sheet, accompanied by enhanced qualitative and quantitative disclosures in the notes to the financial statements. The Update is generally effective for public business entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is in the early stages of its implementation assessment, which includes identifying the population of the Company's leases that are within the scope of the new guidance and gathering all key lease data that will facilitate application of the new accounting requirements.

ASU 2014-09, Revenue From Contracts With Customers (Topic 606), ASU 2015-14 Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date, ASU 2016-08 Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU 2016-10 Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, ASU 2016-11 Revenue Recognition (Topic 605) and Derivatives ad Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting, ASU 2016-12 Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, and ASU 2016-20 Revenue from Contracts with Customers (Topic 606): Technical Corrections and Improvements to Topic 606. The FASB amended existing guidance related to revenue from contracts with customers, superseding and replacing nearly all existing revenue recognition guidance, including industry-specific guidance, establishing a new control-based revenue recognition model, changing the basis for deciding when revenue is recognized over time or at

a point in time, providing new and more detailed guidance on specific topics and expanding and improving disclosures about revenue. In addition, this guidance specifies the accounting for some costs to obtain or fulfill a contract with a customer. The amendments are effective for public entities for annual reporting periods beginning after December 15, 2017. A substantial portion of the Company’s revenues represent interest and fee income generated from financial instruments such as loans and investment securities. Revenues generated from financial instruments such as these are not within the scope of this guidance. Revenue sources that are within the scope of this guidance include service charges and fees on deposit accounts. The Company is in the process of reviewing non-interest income revenue sources to determine if they are within the scope of the new guidance. The Company does not expect the adoption will have a significant impact on its Consolidated Financial Statements.

Note 3 – 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, 2016 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.

Certain Acquired Loans–As part of business acquisitions, the Bank acquires certain loans that have shown evidence of credit deterioration since origination. These acquired loans are recorded at the allocated fair value, such that there is no carryover of the seller’s allowance for loan losses. Such acquired loans are accounted for individually. The Bank estimates the amount and timing of expected cash flows for each purchased loan, and the expected cash flows in excess of the allocated fair value is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan’s contractual principal and interest over expected cash flows is not recorded (non-accretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded through the allowance for loan losses. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income.

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 November 30 as the date 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–The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

Note 4 – Acquisitions

The Company accounted for the following transactions under the acquisition method of accounting, which requires purchased assets and liabilities assumed to be recorded at their respective fair values at the date of acquisition. The Company determined the fair value of the loans, core deposit intangible, securities and deposits with the assistance of third party valuations.

Heritage Oaks Bancorp Acquisition

Effective as of April 1, 2017, the Company completed the acquisition of Heritage Oaks Bancorp ("HEOP"), the holding company of Heritage Oaks Bank, a Paso Robles, California based state-chartered bank (“Heritage Oaks Bank”) with $2.0 billion in total assets, $1.4 billion in gross loans and $1.7 billion in total deposits at March 31, 2017. Heritage Oaks Bank operates branches within San Luis Obispo and Santa Barbara Counties and a loan production office in Ventura County.

Pursuant to the terms of the merger agreement, each outstanding share of HEOP common stock was converted into the right to receive 0.3471 shares of corporate common stock. The value of the total deal consideration was approximately $465 million, which included approximately $3.9 million of aggregate cash consideration payable to holders of Heritage Oaks share-based compensation awards, and the issuance of 11,959,022 shares of the Corporation's common stock, which had a value of $38.55 per share, which was the closing price of the Corporation's common stock on March 31, 2017, the last trading day prior to the consummation of the acquisition.

Goodwill in the amount of $269 million was recognized in the HEOP 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 HEOP as of April 1, 2017 and the fair value adjustments and amounts recorded by the Company in 2017 under the acquisition method of accounting:

The fair values are preliminary estimates and are subject to adjustment for up to one year after the merger date or when additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. In the third quarter of 2017, the Company made a $1.1 million adjustment to deferred tax assets and the deal consideration.

Security California Bancorp Acquisition

On January 31, 2016, the Company completed its acquisition of Security California Bancorp (“SCAF”), whereby we acquired $714 million in total assets, $456 million in loans and $637 million in total deposits. Under the terms of the merger agreement, each share of SCAF common stock was converted into the right to receive 0.9629 shares of the Corporation’s common stock. The value of the total deal consideration was $120 million, which includes $788,000 of aggregate cash consideration to the holders of SCAF stock options and the issuance of 5,815,051 shares of the Corporation’s common stock, valued at $119 million based on a closing stock price of $20.53 per share on January 29, 2016.

SCAF was the holding company of Security Bank of California, a Riverside, California, based state-chartered bank with six branches located in Riverside County, San Bernardino County and Orange County.

Goodwill in the amount of $51.7 million was recognized in the SCAF 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.

Unrealized gains and losses on investment securities available-for-sale are recognized in stockholders’ equity as accumulated other comprehensive income or loss. At September 30, 2017, the Company had an accumulated other comprehensive income of $4.2 million, or $2.5 million net of tax, compared to an accumulated other comprehensive loss of $4.7 million, or $2.7 million net of tax, at December 31, 2016.

At September 30, 2017, mortgage-backed securities ("MBS ") with an estimated par value of $62.4 million and a fair value of $64.2 million were pledged as collateral for the Bank’s three repurchase agreements, which totaled $28.5 million, and homeowner’s association (“HOA”) reverse repurchase agreements, which totaled $18.5 million.

15

At December 31, 2016, MBS with an estimated par value of $63.6million and a fair value of $65.3 million were pledged as collateral for the Bank’s three repurchase agreements, which totaled $28.5 million, and HOA reverse repurchase agreements, which totaled $21.5 million.

At September 30, 2017 and December 31, 2016, there were not holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of shareholders' 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.

The Company did not realize any OTTI recoveries or losses for the three months ended September 30, 2017 and June 30, 2017. However, the Company did realize an OTTI recovery of $2,000 for the three months ended September 30, 2016, which relates to investment income from a previously charge-off investment. A $207,000 OTTI was taken in the first quarter of 2016, related to a CRA investment purchased in June of 2014 with a par value of $50, and a book value of $500,000. In March 2016, the shareholders of the investment voted to approve a sale of the institution at a per share acquisition price less the Bank's book value, and the sale closed in July 2016. The Company is currently waiting to receive the proceeds for its outstanding shares. As a result, the Company's current holdings were written down and the loss recognized.

At September 30, 2017, the Company had $17.3 million in Federal Home Loan Bank (“FHLB”) stock, $25.0 million in Federal Reserve Bank of San Francisco (“FRB”) stock, and $16.1 million in other stock, all carried at cost. During the three months ended September 30, 2016 and December 31, 2016, the FHLB did not repurchase any of the Company’s excess FHLB stock through their stock repurchase program. The Company evaluates its investments in FHLB, FRB and other stock for impairment periodically, including their capital adequacy and overall financial condition. No impairment losses have been recorded through September 30, 2017.

______________________________

(1) Secured by real estate.

(2) Includes second trust deeds.

(3) Total gross loans held for investment for September 30, 2017 are net of the unaccreted fair value purchase discounts of $21.6 million.

From time to time, we may purchase or sell loans in order to manage concentrations, maximize interest income, change risk profiles, improve returns and generate liquidity.

The Company makes residential and commercial loans held for investment to customers located primarily in California. Consequently, the underlying collateral for our loans and a borrower’s ability to repay may be impacted unfavorably by adverse changes in the economy and real estate market in the region.

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 $269.1 million for secured loans and $161.5 million for unsecured loans at September 30, 2017. At September 30, 2017, the Bank’s largest aggregate outstanding balance of loans to one borrower was $45.0 million of secured credit.

Purchased Credit Impaired Loans

The Company has acquired loans as part of its acquisitions of Canyon National Bank in 2011, Palm Desert National Bank in 2012, Independence Bank in 2015, Security Bank of California in 2016 and Heritage Oaks Bank in 2017 for which there was, at acquisition, evidence of deterioration of credit quality since origination and for which it was probable, at acquisition, that all contractually required payments would not be collected. The carrying amount of those loans is as follows:

	September 30, 2017		December 31, 2016
	(dollars in thousands)
Business loans:
Commercial and industrial	$	2,870	$	2,586
Commercial owner occupied	3,019		491
SBA	334		—
Real estate loans:
Commercial non-owner occupied	1,303		1,088
Multi-family	226		—
One-to-four family	257		1
Construction/Land	973		—
Other loans	221		393
Total purchase credit impaired	$	9,203	$	4,559

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 September 30, 2017, the Company had $9.2 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 three months ended September 30, 2017, June 30, 2017 and September 30, 2016 and for the nine months ended September 30, 2017 and 2016:

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

24

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, or 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. All loans are generally charged-off at such 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.

The following table provides additional detail on the components of impaired loans at the period end indicated:

	September 30, 2017		December 31, 2016
	(dollars in thousands)
Nonaccruing loans	$	515	$	1,141
Accruing loans	878		—
Total impaired loans	$	1,393	$	1,141

When loans are placed on nonaccrual status all accrued interest is reversed from earnings. 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 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 collection of interest. The Company had impaired loans on nonaccrual status of $515,000 at September 30, 2017 and $1.1 million at December 31, 2016. The Company had no loans 90 days or more past due and still accruing at September 30, 2017 and December 31, 2016.

At September 30, 2017, the Company had a recorded investment in two TDR loans totaling $878,500. The modification of the terms of the first relationship, totaling $775,500, included the restructuring of three loans related to one borrower into one loan and an extension of the maturity to six years. The modification of the terms of the second relationship, totaling $103,000, included the restructuring of two loans related to one borrower into one loan and an extension of the maturity to three years. There were no TDRs at December 31, 2016. In addition, the Company had $41,000 in consumer mortgage loans collateralized by residential real estate property for which formal foreclosure proceedings were in process as of September 30, 2017 and December 31, 2016.

Concentration of Credit Risk

As of September 30, 2017, 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 and commercial owner occupied real estate and business loans. The Bank maintains policies approved by the Bank’s Board of Directors (the “Bank Board”) that address these concentrations and continues to diversify 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.

25

Credit Quality and Credit Risk Management

The Company’s credit quality is maintained and credit risk managed 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 minimum and 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 Board. The Bank’s seasoned 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 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 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 by the Company’s Credit and Portfolio Review committee, and are reviewed annually by an independent third-party, 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 which contain no well-defined deficiency or weakness.

• 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 portfolio managers also manage loan performance risks, collections, workouts, bankruptcies and foreclosures. Loan performance risks are mitigated by our portfolio managers acting promptly and assertively to address problem credits when they are identified. Collection efforts are commenced 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.

26

When a loan is graded as special mention or 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 the full amount of the Company’s recorded investment in the loan is no longer collectable. The Company typically continues to obtain or confirm 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 by the Company’s internal risk grading as of the periods indicated:

Note 7 – 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 credit losses inherent in the remainder of the loan portfolio. The ALLL is prepared in accordance with the historical loss method, 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 (replacing prior period's interval ranging from 8 to 87 months) with the loss emergence period extending from 1 year to 1.4 years. The aforementioned enhancements did not materially impact the allowance balance at September 30, 2017. 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 management’s judgment, taking into consideration the specific characteristics of the Bank’s portfolio and analysis of results from a select group of the Company’s peers.

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 three and nine months ended for the periods indicated:

Note 8 – Subordinated Debentures

In August 2014, the Corporation issued $60 million in aggregate principal amount of 5.75% Subordinated Notes Due 2024 (the “Notes”) 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 bear interest at an annual fixed rate of 5.75%, and the first interest payment on the Notes occurred on March 3, 2015, and will continue to be payable semiannually each March 3 and September 3 until September 3, 2024. The Notes can only be redeemed, partially or in whole, prior to the maturity date if the notes do not constitute Tier 2 Capital (for purposes of capital adequacy guidelines of the Board of Governors of the Federal Reserve). Outstanding principal and accrued and unpaid 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. These ratings were reaffirmed by KBRA on October 27, 2017.

In March 2004, the Corporation issued $10.3 million of Floating Rate Junior Subordinated Deferrable Interest Debentures (the “Subordinated Debentures”) to PPBI Trust I, which funded the payment of $10 million of Floating Rate Trust Preferred Securities (“Trust Preferred Securities”) issued by PPBI Trust I in March 2004 due April 7, 2034. The net proceeds from the offering of Trust Preferred Securities were contributed as capital to the Bank to support further growth. Interest is payable quarterly on the Subordinated Debentures at three-month LIBOR plus 2.75% per annum, for an effective rate of 4.05% per annum as of September 30, 2017.

On April 1, 2017, as part of the Heritage Oaks 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 3.02% per annum as of September 30, 2017. At September 30, 2017, the carrying value of these debentures was $3.9 million, which reflects purchase accounting fair value adjustments of $1.3 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 September 30, 2017, the carrying value of Mission Community Capital Trust I and Santa Lucia Bancorp (CA) Capital Trust were $2.8 million and $3.7 million, respectively, which reflects purchase accounting fair value adjustments of $332,000 and $1.4 million, respectively. Interest is payable quarterly at three-month LIBOR plus 2.95% per annum, for an effective rate of 4.25% per annum as of September 30, 2017 for Mission Community Capital Trust I. Interest is payable quarterly at three-month LIBOR plus 1.48% per annum, for an effective rate of 2.78% per annum as of September 30, 2017 for Santa Lucia Bancorp (CA) Capital Trust. These three debentures are callable by the Corporation at par.

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 as a component of the Company’s liabilities.

Note 9 – Earnings Per Share

Basic earnings per share excludes dilution and is computed by dividing net income or loss available to common stockholders by the weighted average number of common shares outstanding for the period, excluding common shares in treasury. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted from the issuance of common stock that would then share in earnings and excludes common shares in treasury. Stock options exercisable for shares of common stock are excluded from the computation of diluted earnings per share if they are anti-dilutive due to their exercise price exceeding the average market price during the period.

33

The impact of stock options which are anti-dilutive are excluded from the computations of diluted earnings per share. The dilutive impact of these securities could be included in future computations of diluted earnings per share if the market price of the common stock increases. The following table sets forth the weighted average number of stock options excluded for the periods indicated:

Note 10 – Fair Value of Financial Instruments

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability 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, and for estimating the fair value of financial assets and financial liabilities not recorded 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. Therefore, for substantially all financial instruments, the fair value estimates presented herein are not necessarily indicative of the amounts the Company could have realized in a sales transaction at September 30, 2017, June 30, 2017 and September 30, 2016.

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. The following is a description of both the general and specific valuation methodologies used for certain instruments measured at fair value, as well as the general classification of these instruments pursuant to the valuation hierarchy.

Cash and due from banks – The carrying amounts of cash and short-term instruments approximate fair value due to the liquidity of these instruments.

35

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.

FHLB, FRB, Other Stock – Due to restrictions placed on transferability, it is not practical to determine the fair value of the stock.

Loans Held for Sale — The fair value of loans held for sale is estimated based upon binding contracts and quotes from third party investors resulting in a Level 2 classification.

Loans Held for Investment — The fair value of loans, other than loans on nonaccrual status, was estimated by discounting the remaining contractual cash flows using the estimated current rate at which similar loans would be made to borrowers with similar credit risk characteristics and for the same remaining maturities, reduced by deferred net loan origination fees and the allocable portion of the allowance for loan losses. Accordingly, in determining the estimated current rate for discounting purposes, no adjustment has been made for any change in borrowers’ credit risks since the origination of such loans. Rather, the allocable portion of the allowance for loan losses is considered to provide for such changes in estimating fair value. As a result, this fair value is not necessarily the value which would be derived using an exit price. These loans are included within Level 3 of the fair value hierarchy.

Impaired loans and OREO– Impaired loans and OREO assets are recorded at the fair value less estimated costs to sell at the time of foreclosure. The fair value of impaired loans and OREO assets are generally based on recent real estate appraisals adjusted for estimated selling costs. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value.

Deposit Accounts and Short-term Borrowings — The amounts payable to depositors for demand, savings, and money market accounts, and short-term borrowings are considered to approximate fair value. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities using a discounted cash flow calculation. Interest-bearing deposits and borrowings are included within Level 2 of the fair value hierarchy.

Term FHLB Advances and Other Long-term Borrowings— The fair value of long term borrowings is determined using rates currently available for similar borrowings with similar credit risk and for the remaining maturities and are classified as Level 2.

Subordinated Debentures – The fair value of subordinated debentures is estimated by discounting the balance by the current three-month LIBOR rate plus the current market spread. The fair value is determined based on the maturity date as the Company does not currently have intentions to call the debenture and is classified as Level 2.

Accrued Interest Receivable/Payable – The carrying amounts of accrued interest receivable and accrued interest payable are deemed to approximate fair value.

36

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.

The fair value estimates presented herein are based on pertinent information available to management as of the periods indicated.

The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

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 non-accrual loans for which it has reduced the principal balance to the value of the underlying collateral less the anticipated selling cost. As such, the Company records impaired loans as Level 3. At September 30, 2017, 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 fair value of impaired loans and other real estate owned were determined using Level 3 assumptions, and represents impaired loan and other real estate loan 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.

Note 11 – 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. At September 30, 2017, the Company had swaps with matched terms with an aggregate notional amount of $59.0 million and a fair value of $0.6 million. 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 non-interest 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

39

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 nine months ended September 30, 2017, 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 September 30, 2017 are not designated as hedging instruments.

The following tables summarize the Company's derivative instruments, included in "other assets" and "other liabilities" in the consolidated statements of financial condition. The Company's derivative instruments were acquired as part of the HEOP acquisition, and the Company did not have any at December 31, 2016:

Note 12 – 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.

Financial instruments that are eligible for offset in the consolidated statements of financial condition as of September 30, 2017 are presented in the table below:

Note 13 – Subsequent Events

Pacific Premier Bancorp, Inc. and Plaza Bancorp

On August 9, 2017, the Company announced that it had entered into an agreement to acquire Plaza Bancorp (PLZZ.OTC) ("Plaza"), the holding company of Plaza Bank, a California-chartered banking corporation headquartered in Irvine, California, with seven branches located in Irvine, Manhattan Beach, El Segundo, Pasadena, Montebello, San Diego, California, and Las Vegas, Nevada.

The acquisition was completed on November 1, 2017, whereby we acquired $1.3 billion in total assets, $1.1 billion in loans and $1.1 billion in total deposits. Under the terms of the merger agreement, each share of Plaza common stock was converted into the right to receive 0.2000 shares of Company common stock. Pursuant to such terms, the Company will issue approximately 6,049,447 shares of the Company's Common Stock valued at $40.40 per share, which was the closing price of the Company's Common Stock on October 31, 2017, the last trading day prior to the consummation of the Merger. The value of the total transaction consideration was approximately $251 million, which included approximately $6.5 million in aggregate cash for fractional shares and consideration payable to holders of Plaza options and Plaza warrants in connection with the closing of the Merger.

The Company expects to record goodwill arising from the acquisition consisting largely of synergies and cost savings resulting from combining the operations of the companies. The amount of goodwill is not expected to be deductible for tax purposes. The fair value of intangible assets and acquired assets and liabilities will be determined as of the acquisition date but are still being evaluated as of the date of these financial statements.

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains information and statements that are considered “forward looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These forward-looking statements represent plans, estimates, objectives, goals, guidelines, expectations, intentions, projections and statements of our beliefs concerning future events, business plans, objectives, expected operating results and the assumptions upon which those statements are based. Forward-looking statements include without limitation, any statement that may predict, forecast, indicate or imply future results, performance or achievements, and are typically identified with words such as “may,” “could,” “should,” “will,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” or words or phrases of similar meaning. We caution that the forward-looking statements are based largely on our expectations and are subject to a number of known and unknown risks and uncertainties that are subject to change based on factors which are, in many instances, beyond our control. Actual results, performance or achievements could differ materially from those contemplated, expressed, or implied by the forward-looking statements.

42

The following factors, among others, could cause our financial performance to differ materially from that expressed in such forward-looking statements:

• The strength of the U.S. economy in general and the strength of the local economies in which we conduct operations;

• The effects of, and changes in, trade, monetary and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System (the “Federal Reserve”);

• Inflation/deflation, interest rate, market and monetary fluctuations;

• The timely development of competitive new products and services and the acceptance of these products and services by new and existing customers;

• The impact of changes in financial services policies, laws and regulations, including those concerning taxes, banking, securities and insurance, and the application thereof by regulatory bodies;

• Technological and social media changes;

• The effect of acquisitions we have made or may make, including, without limitation, the failure to achieve the expected revenue growth or expense savings from such acquisitions, or the failure to effectively integrate an acquisition target into our operations;

• Changes in the level of our nonperforming assets and charge-offs;

• The effect of changes in accounting policies and practices, as may be adopted from time-to-time by bank regulatory agencies, the SEC, the Public Company Accounting Oversight Board, the FASB or other accounting standards setters;

• Possible OTTI of securities held by us;

• The impact of current governmental efforts to restructure the U.S. financial regulatory system, including enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank Act")

• Changes in consumer spending, borrowing and savings habits;

• The effects of our lack of a diversified loan portfolio, including the risks of geographic and industry concentrations;

• Ability to attract deposits and other sources of liquidity;

• Changes in the financial performance and/or condition of our borrowers;

• Changes in the competitive environment among financial and bank holding companies and other financial service providers;

• Geopolitical conditions, including acts or threats of terrorism, actions taken by the United States or other governments in response to acts or threats of terrorism and/or military conflicts, which could impact business and economic conditions in the United States and abroad;

• Unanticipated regulatory or judicial proceedings; and

• Our ability to manage the risks involved in the foregoing.

If one or more of the factors affecting our forward-looking information and statements proves incorrect, then our actual results, performance or achievements could differ materially from those expressed in, or implied by, forward-looking information and statements contained in this Quarterly Report on Form 10-Q and other reports and registration statements filed by us with the SEC. Therefore, we caution you not to place undue reliance on our forward-looking information and statements. We will not update the forward-looking information and statements to reflect actual results or changes in the factors affecting the forward-looking information and statements. For information on the factors that could cause actual results to differ from the expectations stated in the forward-looking statements, see “Risk Factors” under Part I, Item 1A of our 2016 Annual Report.

43

Forward-looking information and statements should not be viewed as predictions, and should not be the primary basis upon which investors evaluate us. Any investor in our common stock should consider all risks and uncertainties disclosed in our filings with the SEC, all of which are accessible on the SEC’s website at http://www.sec.gov.

GENERAL

This discussion should be read in conjunction with our Management Discussion and Analysis of Financial Condition and Results of Operations included in our 2016 Annual Report, plus the unaudited consolidated financial statements and the notes thereto appearing elsewhere in this Quarterly Report on Form 10-Q. The results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results expected for the year ending December 31, 2017.

The Corporation is a California-based bank holding company incorporated in the state of Delaware and registered as a bank holding company under the Bank Holding Company Act of 1956, as amended (“BHCA”). Our wholly owned subsidiary, Pacific Premier Bank, is a California state-chartered commercial bank. As a bank holding company, the Corporation is subject to regulation and supervision by the Federal Reserve. We are required to file with the Federal Reserve quarterly and annual reports and such additional information as the Federal Reserve may require pursuant to the BHCA. The Federal Reserve may conduct examinations of bank holding companies, such as the Corporation, and its subsidiaries. The Corporation is also a bank holding company within the meaning of the California Financial Code. As such, the Corporation and its subsidiaries are subject to examination by, and may be required to file reports with, the California Department of Business Oversight-Division of Financial Institutions (“DBO”).

A bank holding company, such as the Corporation, is required to serve as a source of financial strength to its subsidiary depository institutions and to commit resources to support such institutions in circumstances where it might not do so absent such a policy. The Federal Reserve, under the BHCA, has the authority to require a bank holding company to terminate any activity or to relinquish control of a nonbank subsidiary (other than a nonbank subsidiary of a bank) upon the Federal Reserve’s determination that such activity or control constitutes a serious risk to the financial soundness and stability of any bank subsidiary of the bank holding company.

As a California state-chartered commercial bank which is a member of the Federal Reserve, the Bank is subject to supervision, periodic examination and regulation by the DBO and the Federal Reserve. The Bank’s deposits are insured by the FDIC through the Deposit Insurance Fund. In general terms, insurance coverage is up to $250,000 per depositor for all deposit accounts. As a result of this deposit insurance function, the FDIC also has certain supervisory authority and powers over the Bank. If, as a result of an examination of the Bank, the regulators should determine that the financial condition, capital resources, asset quality, earnings prospects, management, liquidity or other aspects of the Bank’s operations are unsatisfactory or that the Bank or our management is violating or has violated any law or regulation, various remedies are available to the regulators. Such remedies include the power to enjoin unsafe or unsound practices, to require affirmative action to correct any conditions resulting from any violation or practice, to issue an administrative order that can be judicially enforced, to direct an increase in capital, to restrict growth, to assess civil monetary penalties, to remove officers and directors and ultimately to request the FDIC to terminate the Bank’s deposit insurance. As a California-chartered commercial bank, the Bank is also subject to certain provisions of California law.

We provide banking services within our targeted markets in California to businesses, including the owners and employees of those businesses, professionals, real estate investors and non-profit organizations, as well as consumers in the communities we serve. Additionally, through our HOA Banking and Lending and Franchise Capital units we can provide customized cash management, electronic banking services and credit facilities to HOAs, HOA management companies and quick service restaurant ("QSR") franchise owners nationwide. Our corporate headquarters are located in Irvine, California. At September 30, 2017, the Bank operated 26 full-service depository branches in California located in the counties of Orange, Los Angeles, Riverside, San Bernardino, San

44

Diego, San Luis Obispo and Santa Barbara. Through our branches and our web site at www.ppbi.com, we offer a broad array of deposit products and services for both business and consumer customers, including checking, money market and savings accounts, cash management services, electronic banking, and on-line bill payment. We also offer a variety of loan products, including commercial business loans, lines of credit, commercial real estate loans, SBA loans, residential home loans, and home equity loans. The Bank funds it's lending and investment activities with retail and commercial deposits obtained through its branches, advances from the FHLB, lines of credit, and wholesale and brokered certificates of deposits.

Our principal source of income is the net spread between interest earned on loans and investments and the interest costs associated with deposits and borrowings used to finance the loan and investment portfolios. Additionally, the Bank generates fee income from loan and investment sales and various products and services offered to both depository and loan customers.

CRITICAL ACCOUNTING POLICIES

Management has established various accounting policies that govern the application of U.S. GAAP in the preparation of our financial statements. Our significant accounting policies are described in the Notes to the Consolidated Financial Statements in our 2016 Annual Report. There have been no significant changes to our Critical Accounting Policies as described in our 2016 Annual Report.

Certain accounting policies require management to make estimates and assumptions which have a material impact on the carrying value of certain assets and liabilities; management considers these to be critical accounting policies. The estimates and assumptions management uses are based on historical experience and other factors, which management believes to be reasonable under the circumstances. Actual results could differ significantly from these estimates and assumptions, which could have a material impact on the carrying value of assets and liabilities at balance sheet dates and our results of operations for future reporting periods.

We consider the ALLL to be a critical accounting policy that requires judicious estimates and assumptions in the preparation of our financial statements that is particularly susceptible to significant change. For further information, see “Allowances for Loan Losses” discussed in Note 7 to the Consolidated Financial Statements in this Quarterly Report on Form 10-Q and Note 5 to the Consolidated Financial Statements in our 2016 Annual Report.

HEOP ACQUISITION

Effective April 1, 2017, the Company acquired HEOP, and its wholly-owned bank subsidiary, Heritage Oaks Bank, a Paso Robles, California, based state-chartered bank, pursuant to the terms of a definitive agreement entered into by the Corporation and HEOP on December 12, 2016. As a result of the HEOP acquisition, the Bank acquired and recorded at the acquisition date assets with a fair value of approximately $2.0 billion, including:

• $1.4 billion of gross loans;

• $443 million in investment securities;

• $269 million in goodwill;

• $78.7 million of cash and cash equivalents;

• $45.5 million of other types of assets;

• $34.9 million in fixed assets; and

• $28.1 million of a core deposit intangible.

Also as a result of the HEOP acquisition, the Company recorded $465 million of equity in connection with the Corporation’s stock issued to HEOP shareholders as part of the acquisition consideration and assumed at acquisition date liabilities with a fair value of approximately $1.8 billion, including:

• $1.7 billion in deposit accounts; and

• $147 million in other liabilities.

The fair values of the assets acquired and liabilities assumed were determined based on the requirements of FASB ASC Topic 820: Fair Value Measurements and Disclosures. Such fair values are preliminary estimates and are subject to adjustment for up to one year after the merger date or when additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier.

46

The acquisition was an opportunity for the Company to further strengthen its competitive position and move into the Central Coast of California. The integration and system conversion of HEOP was completed in July 2017.

SCAF ACQUISITION

Effective January 31, 2016, the Company acquired SCAF, and its wholly-owned bank subsidiary, Security Bank of California, a Riverside, California, based state-chartered bank, pursuant to the terms of a definitive agreement entered into by the Corporation and SCAF on October 2, 2015. As a result of the SCAF acquisition, the Bank acquired and recorded at the acquisition date assets with a fair value of approximately $765 million, including:

• $456 million of gross loans;

• $190 million in investment securities;

• $51.7 million in goodwill;

• $40.9 million of cash and cash equivalents;

• $18.1 million of other types of assets;

• $4.2 million in fixed assets; and

• $4.3 million of a core deposit intangible.

Also as a result of the SCAF acquisition, the Company recorded $119 million of equity in connection with the Corporation’s stock issued to SCAF shareholders as part of the acquisition consideration and assumed at acquisition date liabilities with a fair value of approximately $645 million, including:

• $637 million in deposit transaction accounts; and

• $8.8 million other liabilities.

The fair values of the assets acquired and liabilities assumed were determined based on the requirements of FASB ASC Topic 820: Fair Value Measurements and Disclosures. Such fair values are preliminary estimates and are subject to adjustment for up to one year after the merger date or when additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. In the second quarter of 2016, the Company made a $146,000 adjustment to fixed assets and goodwill. As of March 31, 2017, the Company finalized its fair values with this acquisition.

The acquisition was an opportunity for the Company to further strengthen its competitive position as one of the premier community banks headquartered in Southern California. The integration and system conversion of SCAF was completed in April 2016.

NON-GAAP MEASURES

For periods presented below, return on average tangible common equity is a non-GAAP financial measures derived from U.S. GAAP-based amounts. We calculate these figures by excluding core deposit intangible ("CDI") amortization expense and exclude the average CDI and average goodwill from the average stockholders’ equity during the period. Management believes that the exclusion of such items from these financial measures provides useful information to an understanding of the operating results of our core business. However, these non-GAAP financial measures are supplemental and are not a substitute for an analysis based on U.S. GAAP measures. As other companies may use different calculations for these adjusted measures, this presentation may not be comparable to other similarly titled adjusted measures reported by other companies.

RESULTS OF OPERATIONS

In the third quarter of 2017, we reported net income of $20.2 million, or $0.50 per diluted share. This compares with net income of $14.2 million, or $0.35 per diluted share, for the second quarter of 2017. The increase in net income was primarily driven by a decrease in noninterest expense of $8.9 million, principally due to a $9.6 million decrease in merger-related expense, partially offset by an increase in income tax expense of $3.1 million.

Net income of $20.2 million, or $0.50 per diluted share, for the third quarter of 2017 compares to net income for the third quarter of 2016 of $9.2 million, or $0.33 per diluted share. The increase in net income of $11.0 million was primarily due to the $25.3 million increase in net interest income resulting from average interest-earning asset growth of $2.4 billion. The increase in average interest-earning assets was primarily from the acquisition of HEOP and organic loan growth since the end of the third quarter of 2016. The increase was partially offset by an $13.8 million increase in noninterest expense, including increases of $7.5 million in compensation and benefits expenses, $1.4 million in premises and occupancy, $1.2 million in legal, audit and professional expense, $1.2 million in CDI amortization expense, and $503,000 in merger-related expenses.

For the three months ended September 30, 2017, the Company’s return on average assets was 1.26% and return on average tangible common equity was 15.02%. For the three months ended June 30, 2017, the return on average assets was 0.89% and the return on average tangible common equity was 11.33%. For the three months ended September 30, 2016, the return on average assets was 1.00% and the return on average tangible common equity was 11.35%.

For the nine months ended September 30, 2017, the Company recorded net income of $43.9 million, or $1.20 per diluted share. This compares with net income of $28.2 million or $1.03 per diluted share for the nine months ended September 30, 2016. The increase in net income of $15.8 million was mostly due to the $58.6 million increase in net interest income resulting from earning asset growth, primarily from the acquisition of HEOP and organic loan growth, partially offset by growth in non-interest expense of $44.7 million, including increases of $19.2 million in compensation and benefits expenses associated with both the acquisition of HEOP and an increase in staffing to support organic growth and $12.0 million in merger-related expenses. Prior period comparisons for the year-to-date results are impacted by the acquisition of HEOP in the second quarter of 2017 and the acquisition of SCAF in the first quarter of 2016.

For the nine months ended September 30, 2017, the Company’s return on average assets was 1.56% and return on average tangible common equity was 12.67%, compared with a return on average assets of 1.60% and a return on average tangible common equity of 12.30% for the nine months ended September 30, 2016.

Net Interest Income

Our primary source of revenue is net interest income, which is the difference between the interest earned on loans, investment securities, and interest earning balances with financial institutions (“interest-earning assets”) and the interest paid on deposits and borrowings (“interest-bearing liabilities”). Net interest margin is net interest income expressed as a percentage of average interest earning assets. Net interest income is affected by changes in both interest rates and the volume of interest-earning assets and interest-bearing liabilities.

Net interest income totaled $64.3 million in the third quarter of 2017, an increase of $953,000 or 1.5%, from the second quarter of 2017. The increase in net interest income was primarily due to an increase in average loan balances and the impact of higher loan yields, driven principally by the Federal Reserve June rate hike, primarily offset by lower accretion income and prepayment fees, as well as higher deposit costs.

49

Net interest margin decreased from 4.40% to 4.34% in the current quarter, entirely driven by lower accretion income of $2.9 million, compared to $4.2 million of accretion income in the second quarter of 2017. Excluding the impact of accretion, our net interest margin expanded 5 basis points to 4.14%, compared with 4.09% in the second quarter as portfolio loan yields expanded by 7 basis points overall. Partially offsetting these favorable increases were higher deposit interest costs of 3 basis points to 28 basis points, as well as as a decrease in prepayment fees of approximately $400,000.

Net interest income for the third quarter of 2017 increased $25.3 million, or 65%, compared to the third quarter of 2016. The increase was related to an increase in average interest-earning assets of $2.4 billion, which resulted primarily from our organic loan growth since the end of the third quarter of 2016 and our acquisition of HEOP during the second quarter of 2017.

For the first nine months ended 2017, net interest income increased $58.6 million, or 53%, compared to the first nine months ended 2016. The increase was related to an increase in average interest-earning assets of $1.8 billion, which resulted primarily from our organic loan growth since the end of the first nine months ended 2016 and our acquisition of HEOP during the second quarter of 2017.

The following tables present for the periods indicated the average dollar amounts from selected balance sheet categories calculated from daily average balances and the total dollar amount, including adjustments to yields and costs, of:

• Interest income earned from average interest-earning assets and the resultant yields; and

• Interest expense incurred from average interest-bearing liabilities and resultant costs, expressed as rates.

50

The tables below set forth our net interest income, net interest rate spread and net interest rate margin for the periods indicated. The net interest rate margin reflects the relative level of interest-earning assets to interest-bearing liabilities and equals our net interest rate spread divided by average interest-earning assets for the periods indicated.

Changes in our net interest income are a function of changes in volumes, days in a period and rates of interest-earning assets and interest-bearing liabilities. The following table presents the impact the volume, days in a period and rate changes have had on our net interest income for the periods indicated. For each category of interest-earning assets and interest-bearing liabilities, we have provided information on changes to our net interest income with respect to:

• Changes in volume (changes in volume multiplied by prior rate);

• Changes in days in a period (changes in days in a period multiplied by daily interest);

• Changes in interest rates (changes in interest rates multiplied by prior volume); and

• The net change or the combined impact of volume, days in a period and rate changes allocated proportionately to changes in volume, days in a period and changes in interest rates.

Provision for Loan Losses

A provision for loan losses of $2.0 million was recorded for the third quarter of 2017, compared with a provision for loan losses of $1.9 million for the quarter ended June 30, 2017. The small increase in our provision for loan losses was primarily due to organic loan growth. Net loan recoveries were $39,000 for the recent quarter of 2017, compared with net loan recoveries of $76,000 for the quarter ended June 30, 2017.

The $2.0 million provision for loan losses during the third quarter of 2017 decreased by $2.0 million from

the third quarter of 2016. Net loan recoveries were $39,000 for the third quarter of 2017, compared with net loan charge-offs of $1.1 million from the third quarter of 2016.

For the first nine months of 2017, we recorded a $6.5 million provision for loan losses, a decrease from

$6.7 million recorded for the first nine months of 2016. Net loan charge-offs amounted to $608,000 for the first nine months of 2017, a decrease from $2.2 million for the first nine months of 2016.

For purchased credit impaired loans, charge-offs are recorded when there is a decrease in the estimated cash flows of the credit from original cash flow estimates. Purchased credit impaired loans were recorded at their estimated fair value, which incorporated our estimated expected cash flows until the ultimate resolution of these credits. To the extent actual or projected cash flows are less than originally estimated, additional provisions for loan losses or charge-offs will be recognized into earnings or against the allowance, if applicable. To the extent actual or projected cash flows are more than originally estimated, the increase in cash flows is prospectively recognized in loan interest income. Due to the accounting rules associated with our purchased credit impaired loans, each quarter we are required to re-estimate cash flows which could cause volatility in our reported net interest margin and provision for loan losses. During the three and nine months ended September 30, 2017, no additional allowance was recorded associated with certain purchased credit impaired loans. See “Allowance for Loan Losses” discussed below in this Quarterly Report on Form 10-Q.

Noninterest Income

Noninterest income for the third quarter of 2017 was $8.2 million, a decrease of $538,000, or 6%, from the second quarter of 2017. The decrease from the second quarter of 2017 was primarily related to a $1.2 million decrease in net gain from the sale of investment securities, partially offset by a $552,000 increase in net gain from the sale of loans and increases in loan servicing and deposit fees.

During the third quarter of 2017, the Bank sold $31.9 million of Small Business Administration ("SBA") loans for a gain of $3.1 million, compared with $29.2 million of SBA loans sold and a gain of $2.9 million in the prior quarter. Additionally, the Bank sold one-to-four family loans during the third quarter of 2017, totaling $37.0 million for a gain of $386,000.

Noninterest income for the third quarter of 2017 increased $2.3 million, or 38%, compared to the third quarter of 2016. The increase from the third quarter of 2016 was primarily related to a $869,000 increase in other income, $695,000 increase in deposit fees, a $384,000 increase in net gain from the sale of investment securities and a $317,000 increase in net gain from sales of loans.

For the first nine months of 2017, noninterest income totaled $21.7 million, an increase from $15.3 million for the first nine months of 2016. The increase was primarily related to higher net gain from sale of loans of $2.0 million and higher net gain from sales of investment securities of $1.2 million. In addition, higher deposit service charges of $1.3 million and higher other income of $2.0 million were recognized, which includes higher debit card and other fees of $1.7 million, primarily as a result of the HEOP acquisition in the second quarter of 2017.

55

Noninterest Expense

 Noninterest expense totaled $39.6 million for the third quarter of 2017, a decrease of $8.9 million, or 18%, compared with the second quarter of 2017. The decrease was primarily driven by merger-related expenses of $503,000 in the third quarter of 2017 compared with $10.1 million for the second quarter of 2017. Excluding the merger-related expense, our noninterest expense increased to $39.1 million compared with $38.4 million for the second quarter of 2017. The increase was primarily driven by an increase in legal, audit and professional expenses of $697,000, a $409,000 increase in other expense, due primarily to CRA related charitable contributions, and a $283,000 increase in premises and occupancy expense, as we expand our facilities to accommodate our growth. These increases were partially offset by a decrease of $439,000 in FDIC insurance premiums, as we adjusted the accrual following the HEOP acquisition, and a $357,000 decrease in data processing expense, as we realized cost savings upon converting the HEOP systems early in the third quarter of 2017.

In comparison to the third quarter of 2016, noninterest expense grew by $13.8 million, or 53%. The increase in expense was primarily related to the additional costs from the operations, personnel and branches retained from the acquisition of HEOP, combined with our continued investment in personnel and systems to support our organic growth.

Noninterest expense totaled $118 million for the first nine months of 2017, an increase of $44.7 million, or 61%, compared with the first nine months of 2016. The increase was primarily driven by higher compensation and benefits expense during the first nine months of 2017 of $19.2 million, as well as merger-related expense of $15.6 million for the HEOP acquisition in the first nine months of 2017 compared with $3.6 million for the first nine months of 2016 for the SCAF acquisition.

The Company’s efficiency ratio was 52.1% for the third quarter of 2017, compared to 52.3% for the second quarter of 2017 and 57.0% for the third quarter of 2016. The Company's efficiency ratio was 52.3% for the first nine months of 2017, compared to 54.8% for the first nine months of 2016.

Income Taxes

For the three months ended September 30, 2017, June 30, 2017 and September 30, 2016, income tax expense was $10.6 million, $7.5 million and $5.9 million, respectively, and the effective income tax rate was 34.4%, 34.7% and 38.9%, respectively. The quarter's rate was favorably impacted by a $1.1 million true-up with the filing of the 2016 tax return and, to a lesser extent, the tax rate deductibility of equity stock expense related to the adoption of ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Accounting.

The Company did not have unrecognized tax benefits that related to uncertainties associated with federal and state income tax matters as of September 30, 2017 and December 31, 2016.

The Company and its subsidiaries are subject to U.S. federal income tax, as well as state income and franchise taxes in multiple state jurisdictions. The statute of limitations related to the consolidated federal income tax returns is closed for all tax years up to and including 2012. The expiration of the statute of limitations related to the various state income and franchise tax returns varies by state.

The Company accounts for income taxes by recognizing deferred tax assets and liabilities based upon temporary differences between the amounts for financial reporting purposes and tax basis of its assets and liabilities. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In assessing the realization of deferred tax assets, management evaluates both positive and negative evidence, including the existence of any cumulative losses in the current year and the prior two years, the amount of taxes paid in available carry-back years, the forecasts of future income, applicable tax planning strategies, and assessments of current and future economic and business

56

conditions. This analysis is updated quarterly and adjusted as necessary. Based on this analysis, Management has determined that a valuation allowance for deferred tax assets was not required as of September 30, 2017. 

FINANCIAL CONDITION

At September 30, 2017, assets totaled $6.5 billion, an increase of $2.5 billion, or 62%, from December 31, 2016. The increase in assets since December 31, 2016 was primarily due to the acquisition of HEOP, which after purchase accounting adjustments, added $1.4 billion in gross loans and $443 million in investment securities, of which $244 million were sold subsequent to the acquisition, and goodwill of $269 million was recognized in the acquisition.

Loans

Loans held for investment totaled $5.0 billion at September 30, 2017, an increase of $1.8 billion, or 55%, from December 31, 2016. The increase from December 31, 2016 was primarily due to the acquisition of HEOP, which after purchase accounting adjustments, added $1.4 billion in gross loans and organic loan commitments of $1.5 billion during the first nine months of 2017.

Loans held for sale increased $36.6 million from December 31, 2016 as a result of the inclusion of $32 million of one-to-four family loans earmarked for sale in the fourth quarter.

The total end-of-period weighted average contractual interest rate on loans, excluding fees and discounts, at September 30, 2017 was 4.81%, compared to 4.81% at December 31, 2016.

Delinquent Loans.  When a borrower fails to make required payments on a loan and does not cure the delinquency within 30 days, we normally record a notice of default and, after providing the required notices to the borrower, commence foreclosure proceedings. If the loan is not reinstated within the time permitted by law, we may sell the property at a foreclosure sale. At these foreclosure sales, we generally acquire title to the property. Loans delinquent 30 or more days as a percentage of loans held for investment were 0.07% at September 30, 2017, compared to 0.03% at December 31, 2016.

Allowance for Loan Losses.  The ALLL represents an estimate of probable incurred losses inherent in our loan portfolio and is based on our continual review of credit quality of the loan portfolio. The allowance contains a specific reserve component for loans that are determined to be impaired and a general reserve component for loans without credit impairment. The general reserve is determined by applying a systematically derived loss factor to individual segments of the loan portfolio. The adequacy and appropriateness of the ALLL and the individual loss factors are reviewed each quarter by management.

The loss factor for each segment of our loan portfolio is generally based on our actual historical loss rate experience supplemented by industry data where we lack loss history experience. The loss factor is adjusted by

59

qualitative adjustment factors to arrive at a final loss factor for each loan portfolio segment. For additional information regarding the qualitative adjustments, please see “Allowances for Loan Losses” as discussed in our 2016 Annual Report. The qualitative factors allow management to assess current trends within our loan portfolio and the economic environment to incorporate their effect when calculating the ALLL. The final loss factors are applied to pass graded loans within our loan portfolio. Higher factors are applied to loans graded below pass, including classified and criticized assets.

No assurance can be given that we will not, in any particular period, sustain loan losses that exceed the amount reserved, or that subsequent evaluation of our loan portfolio, in light of the prevailing factors, including economic conditions which may adversely affect our market area or other circumstances, will not require significant increases in the loan loss allowance. In addition, regulatory agencies, as an integral part of their examination process, periodically review our ALLL and may require us to recognize additional provisions to increase the allowance or take charge-offs in anticipation of future losses.

At September 30, 2017, our ALLL was $27.1 million, an increase of $5.8 million from December 31, 2016. The increase in the allowance for loan losses at September 30, 2017 was mainly attributable to loan growth in the loan portfolio and, to a lesser extent, net loan charge-offs of $608,000. At September 30, 2017, given the composition of our loan portfolio, as well as the unamortized fair value discount of loans acquired, the ALLL was considered adequate to cover probable incurred losses inherent in the loan portfolio. Should any of the factors considered by management in evaluating the appropriate level of the ALLL change, the Company’s estimate of probable incurred loan losses could also change, which could affect the level of future provisions for loan losses.

Investment Securities

We primarily use our investment portfolio for liquidity purposes and to support our interest rate risk management strategies. Investment securities available-for-sale totaled $704 million at September 30, 2017, an increase of $323 million, or 85%, from December 31, 2016. The increase in investment securities from December 31, 2016 was primarily the result of the acquisition of HEOP, which at acquisition added $445 million of securities, before purchase accounting adjustments, and purchases of $187 million, partially offset by approximately $244 million in sales of securities resulting in a gain of $3.0 million.

Each quarter, we review individual securities classified as available-for-sale to determine whether a decline in fair value below the amortized cost basis is other-than-temporary. If it is probable that we will be unable to collect all amounts due according to the contractual terms of the debt security, an OTTI write-down is recorded against the security and a loss recognized.

In determining if a security has an OTTI loss, we consider the 1) length of time and the extent to which the fair value has been less then amortized cost; 2) financial condition and near term prospects of the issuer; 3) impact of changes in market interest rates; and 4) intent and ability of the Company to retain its investment for a period of time sufficient to allow any anticipated recovery in fair value and whether it is not more likely than not the Company would be required to sell the security. We estimate OTTI losses on a security primarily through:

• An evaluation of the present value of estimated cash flows from the security using the current yield to accrete beneficial interest and including assumptions in the prepayment rate, default rate, delinquencies, loss severity and percentage of nonperforming assets;

• An evaluation of the estimated payback period to recover principal;

• An analysis of the credit support available in the underlying security to absorb losses; and

• A review of the financial condition and near term prospects of the issuer.

63

The Company realized no OTTI recovery for the quarters ended September 30, 2017 and December 31, 2016. The Company realized OTTI recovery of $2,000 for the quarter ended September 30, 2016. We recorded no impairment credit losses on available-for-sale securities in our consolidated statements of income for the three months ended September 30, 2017, December 31, 2016 and September 30, 2016. A $207,000 OTTI was taken during the quarter ended March 31, 2016, related to a CRA investment purchased in June 2014 with a par value of $50, and a book value of $500,000.

Nonperforming Assets

Nonperforming assets consist of loans on which we have ceased accruing interest (nonaccrual loans), restructured loans and OREO. It is our general policy to account for a loan as nonaccrual when the loan becomes 90 days delinquent or when collection of interest appears doubtful.

Nonperforming assets totaled $887,000, or 0.01% of total assets at September 30, 2017, a decrease from $1.6 million, or 0.04% of total assets at December 31, 2016. At September 30, 2017, nonperforming loans totaled $515,000, or 0.01% of loans held for investment, a decrease from $1.1 million, or 0.04% of loans held for investment at December 31, 2016. Other real estate owned decreased to $372,000.

Stockholders’ Equity.  Total stockholders’ equity was $982 million as of September 30, 2017, an increase from $460 million at December 31, 2016. The current year increase of $522 million in stockholders’ equity was primarily related to the issuance of $465 million of stock in the acquisition of HEOP as well as net income for the first nine months of 2017 of $43.9 million.

66

Our book value per share increased to $24.44 at September 30, 2017 from $16.54 at December 31, 2016. At September 30, 2017, the Company’s tangible common equity to tangible assets ratio was 9.41%, an increase from 8.86% at December 31, 2016.

Tangible common equity to tangible assets (the “tangible common equity ratio”) is a non-GAAP financial measure derived from GAAP-based amounts. We calculate the tangible common equity ratio by deducting the balance of intangible assets from common shareholders’ equity and dividing by period end tangible assets which also deducts intangible assets. We believe that this information is important to shareholders as tangible equity is a measure that is consistent with the calculation of capital for bank regulatory purposes, which excludes intangible assets from the calculation of risk-based ratios.

CAPITAL RESOURCES AND LIQUIDITY

Our primary sources of funds are deposits, advances from the FHLB and other borrowings, principal and interest payments on loans, and income from investments. While maturities and scheduled amortization of loans are a predictable source of funds, deposit inflows and outflows as well as loan prepayments are greatly influenced by general interest rates, economic conditions, and competition.

Our primary sources of funds generated during the first nine months of 2017 were from:

• Proceeds of $248 million from the sale or maturity of securities available-for-sale;

• Net increase of $203 million in deposit accounts;

• Cash of $76.5 million acquired in the acquisition;

• Proceeds of $100.9 million from the sale and principal payments on loans held for sale; and

• Principal payments on securities available-for-sale of $55.5 million.

We used these funds to:

• Originate loans of $588 million;

• Purchase of securities available-for-sale of $169 million;

• Originate loans held for sale of $130.0 million; and

• Reduce borrowings by $74.3 million.

Our most liquid assets are unrestricted cash and short-term investments. The levels of these assets are dependent on our operating, lending and investing activities during any given period. Our liquidity position is

67

continuously monitored and adjustments are made to the balance between sources and uses of funds as deemed appropriate. At September 30, 2017, cash and cash equivalents totaled $121 million and the market value of our investment securities available-for-sale totaled $704 million. If additional funds are needed, we have additional sources of liquidity that can be accessed, including FHLB advances, federal fund lines, the Federal Reserve’s lending programs and loan sales. As of September 30, 2017, the maximum amount we could borrow through the FHLB was $2.9 billion, of which $931 million was available for borrowing based on collateral pledged of $1.1 billion in real estate loans. At September 30, 2017, we had $335 million in FHLB borrowings against that available balance. At September 30, 2017, we also had unsecured lines of credit aggregating $221 million, which consisted of $168 million with other financial institutions from which to draw funds and $3.3 million with the FRB and one reverse repo line with a correspondent bank of $50 million. For the quarter ended September 30, 2017, our average liquidity ratio was 10.59%, which is above the Company's policy of 10.0%. The Company regularly models liquidity stress scenarios to ensure that adequate liquidity is available and has contingency funding plans in place which are reviewed and tested on a regular basis.

To the extent that 2017 deposit growth is not sufficient to satisfy our ongoing commitments to fund maturing and withdrawable deposits, repay maturing borrowings, fund existing and future loans, or make investments, we may access funds through our FHLB borrowing arrangement, unsecured lines of credit or other sources.

The Bank has a policy in place that permits the purchase of brokered funds, in an amount not to exceed 15% of total deposits, as a secondary source for funding. At September 30, 2017, we had $240 million in brokered time deposits, which constituted 4.8% of total deposits at that date.

The Corporation is a corporate entity separate and apart from the Bank that must provide for its own liquidity. The Corporation's primary sources of liquidity are dividends from the Bank. In addition, the Corporation maintains a line of credit with Wells Fargo, with availability of $15 million. There are statutory and regulatory provisions that limit the ability of the Bank to pay dividends to the Corporation. Management believes that such restrictions will not have a material impact on the ability of the Corporation to meet its ongoing cash obligations.

The Corporation has never declared or paid dividends on its common stock and, at this time, does not anticipate declaring or paying any cash dividends in the foreseeable future. The Corporation’s board of directors authorized in June 2012 a stock repurchase plan, which allows the Corporation to proactively manage its capital position and return excess capital to its stockholders. The repurchase plan authorizes the repurchase of up to 1,000,000 shares of the Company’s common stock. Shares purchased under such plans also provide the Corporation with shares of common stock necessary to satisfy obligations related to stock compensation awards. Also, please see Part II, Item 2 - Unregistered Sales of Equity Securities and Use of Proceeds for additional information.

Contractual Obligations and Off-Balance Sheet Commitments

Contractual Obligations.  The Company enters into contractual obligations in the normal course of business primarily as a source of funds for its asset growth and to meet required capital needs.

Off-Balance Sheet Commitments.  We utilize off-balance sheet commitments in the normal course of business to meet the financing needs of our customers and to reduce our own exposure to fluctuations in interest rates. These financial instruments include commitments to originate real estate, business and other loans held for investment, undisbursed loan funds, lines and letters of credit, and commitments to purchase loans and investment securities for portfolio. The contract or notional amounts of those instruments reflect the extent of involvement we have in particular classes of financial instruments.

Commitments to originate loans held for investment are agreements to lend to a customer as long as there is no violation of any condition established in the commitment. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some commitments expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Undisbursed loan funds and unused lines of credit on home equity and commercial loans include committed funds not disbursed. Letters of credit are conditional commitments we issue to guarantee the performance of a customer to a third party.As of September 30, 2017, we had commitments to extend credit on existing lines and letters of credit of $1.0 billion, compared to $581 million at December 31, 2016 and $576 million at September 30, 2016.

The following table summarizes our contractual commitments with off-balance sheet risk by expiration period at the date indicated:

Regulatory Capital Compliance

The Company and the Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and the Bank’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s and the Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain capital in order to meet certain capital ratios to be considered adequately capitalized or well capitalized under the regulatory framework for prompt corrective action. As of the most recent formal notification from the Federal Reserve, the Company and the Bank was categorized as “well capitalized.” There are no conditions or events since that notification that management believes have changed the Bank’s categorization.

New comprehensive regulatory capital rules for U.S. banking organizations pursuant to the capital framework of the Basel Committee on Banking Supervision, generally referred to as “Basel III”, became effective for the Company and the Bank on January 1, 2015, subject to phase-in periods for certain of their components and other provisions. The most significant of the provisions of the new capital rules which apply to the Company and the Bank are as follows: the phase-out of trust preferred securities from Tier 1 capital, the higher risk-weighting of high volatility and past due real estate loans and the capital treatment of deferred tax assets and liabilities above certain thresholds.

Beginning January 1, 2016, Basel III implemented a requirement for all banking organizations to maintain a capital conservation buffer above the minimum risk-based capital requirements in order to avoid certain limitations on capital distributions, stock repurchases and discretionary bonus payments to executive officers. The capital conservation buffer is exclusively comprised of common equity tier 1 capital, and it applies to each of the three risk-based capital ratios but not to the leverage ratio. At September 30, 2017, the Company and Bank are in compliance with the capital conservation buffer requirement. The capital conservation buffer will increase by 0.625% each year starting in 2016 through 2019, at which point, the common equity tier 1, tier 1 and total capital ratio minimums inclusive of the capital conservation buffer will be 7.0%, 8.5% and 10.5%, respectively.

70

As defined in applicable regulations and set forth in the table below, the Company and the Bank continue to exceed the regulatory capital minimum requirements and the Bank continues to exceed the “well capitalized” standards at the dates indicated:

Item 3.  Quantitative and Qualitative Disclosure About Market Risk

Management believes that there have been no material changes in our quantitative and qualitative information about market risk since December 31, 2016.  For a complete discussion of our quantitative and qualitative market risk, see “Item 7A. Quantitative and Qualitative Disclosure About Market Risk” in our 2016 Annual Report.

71

Item 4.  Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, an evaluation was carried out by our management, with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report.

Changes in Internal Controls

There have not been any changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) during the fiscal quarter to which this Quarterly Report on Form 10-Q relates that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

72

PART II - OTHER INFORMATION

Item 1.  Legal Proceedings

There are no material pending legal proceedings, other than ordinary routine litigation incidental to our business. Management believes that none of the legal proceedings occurring in the ordinary course of business, individually or in the aggregate, will have a material adverse impact on the results of operations or financial condition of the Company.

Item 1A. Risk Factors

The description of the risk factors associated with the Company’s business previously disclosed in Part I, Item 1A of our 2016 Annual Report is supplemented to include the following updated risk factor:

Existing and potential acquisitions may disrupt our business and dilute stockholder value.

On April 1, 2017, we completed the acquisition of HEOP, the holding company of Heritage Oaks Bank, a California state-chartered bank with $2.0 billion in total assets. On November 1, 2017, we completed the acquisition of Plaza, the holding company of Plaza Bank, a California-chartered banking corporation with $1.3 billion in total assets.

The success of these mergers will depend on, among other things, our ability to realize the anticipated revenue enhancements and efficiencies and to combine the businesses of Pacific Premier with those of HEOP and Plaza in a manner that does not materially disrupt the existing customer relationships of HEOP or Plaza or result in decreased revenues resulting from any loss of customers, and that permits growth opportunities to occur. If we are not able to successfully achieve these objectives, the anticipated benefits of the mergers may not be realized fully or at all or may take longer to realize than expected.

It is possible that the ongoing HEOP integration process and the Plaza integration process could result in the loss of key employees, the disruption of ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits of the mergers.  Integration efforts could also divert management attention and resources. These integration matters could have an adverse effect on the combined company.

In addition, we issued 11,959,022 shares of our common stock in connection with the HEOP acquisition. We expect to issue approximately 6,049,447 shares of our common stock as consideration for the acquisition of Plaza. All of the shares of our common stock issued to former HEOP and Plaza shareholders in the mergers are freely tradable without restrictions under the Securities Act. If former HEOP and Plaza holders sell substantial amounts of our common stock, it may cause the market price of our common stock to decrease.

We continue to evaluate merger and acquisition opportunities and conduct due diligence activities related to possible transactions with other financial institutions on an ongoing basis.  As a result, merger or acquisition discussions and, in some cases, negotiations may take place and future mergers or acquisitions involving cash, debt or equity securities may occur at any time.  Acquisitions typically involve the payment of a premium over book and market values, and, therefore, some dilution of our stock’s tangible book value and net income per common share may occur in connection with any future transaction.  Furthermore, failure to realize the expected revenue increases, cost savings, increases in geographic or product presence, and/or other projected benefits from recent or future acquisitions could have a material adverse effect on our financial condition and results of operations.

We cannot say with any certainty that we will be able to consummate, or if consummated, successfully integrate future acquisitions or that we will not incur disruptions or unexpected expenses in integrating such acquisitions.  In attempting to make such future acquisitions, we anticipate competing with other financial institutions, many of which have greater financial and operational resources.  Acquiring other banks, businesses, or branches involves various risks commonly associated with acquisitions, including, among other things:

73

• Potential exposure to unknown or contingent liabilities of the target company;

• Exposure to potential asset quality issues of the target company;

• Potential disruption to our business;

• Potential diversion of management’s time and attention;

• The possible loss of key employees and customers of the target company;

• Difficulty in estimating the value of the target company; and

• Potential changes in banking or tax laws or regulations that may affect the target company.

Item 2.  Unregistered Sales of Equity Securities and Use of Proceeds

On June 25, 2012, the board of directors authorized its second stock repurchase program. Under the repurchase program, management is authorized to repurchase up to 1,000,000 shares of the Company’s common stock. The program may be limited or terminated at any time without prior notice. The following table provides information with respect to purchases made by or on behalf of us or any “affiliated purchaser” (as defined in Rule 10b-18(a)(3) under the Exchange Act) of our common stock during the third quarter of 2017.

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 consolidated financial statements contain all adjustments (consisting of normal recurring accruals) necessary to present fairly the Company’s financial position as of September 30, 2017 and December 31, 2016, the results of its operations and comprehensive income for the three months ended September 30, 2017, June 30, 2017 and September 30, 2016 and the nine months ended September 30, 2017 and September 30, 2016 and the changes in stockholders’ equity and cash flows for the nine months ended September 30, 2017 and 2016. Operating results or comprehensive income for the nine months ended September 30, 2017 are not necessarily indicative of the results or comprehensive income that may be expected for any other interim period or the full year ending December 31, 2017.

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, 2016 (the “2016 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, and Santa Lucia Bancorp (CA) Capital Trust, 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 2017

In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Accounting. The amendments simplify several aspects of the accounting for share-based payment award transactions, including accounting for excess tax benefits and tax deficiencies, classifying excess tax benefits on the statement of cash flows, accounting for forfeitures, classifying awards that permit share repurchases to satisfy statutory tax-withholding requirements and classifying tax payments on behalf of employees on the statement of cash flows. For public business entities, the amendment is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is permitted for any organization in any interim or annual period. As a result of the adoption of ASU 2016-09, the Company began recognizing the tax effects of exercised or vested awards as discrete items in the reporting period in which they occur, resulting in a $355,000 and a $2.0 million tax benefit to the Company for the three and nine months ended September 30, 2017, respectively.

In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships. The amendments clarify that a change in the counterparty to a derivative instrument designated as a hedging instrument does not, in and of itself, require designation of that hedging relationship provided that all other hedge accounting criteria remain the same. The Update is effective for public business entities for fiscal years beginning after December 31, 2016, including interim periods within those years. The adoption of this standard did not have a material effect on the Company's operating results or financial condition.

Recent Accounting Guidance Not Yet Effective

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. The amendments provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. Modification accounting will apply unless all of the following are the same immediately before and after the modification:

• The award’s fair value – or calculated value or intrinsic value, if an alternative method is used. If the modification does not affect any inputs to the valuation of the award, estimating the value immediately before and after the modification is not required.

• The award’s vesting provisions

• The award’s classification as an equity instrument or a liability instrument

The Update is effective for all entities for fiscal years beginning after December 15, 2017, including interim periods within those years. The amendments should be applied prospectively to awards modified on or after the effective date. The adoption of this standard will not material effect the Company's operating results or financial condition, as historically the Company has not modified share-based awards.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For public business entities, the amendment is effective for annual periods beginning after December 15, 2019 and interim period within those annual periods. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures. The Company is in the process of compiling key data elements and considering software models that will meet the requirements of the new guidance.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new standard is being issued to increase the transparency and comparability around lease obligations. Previously unrecorded off-balance sheet obligations will now be brought more prominently to light by presenting lease liabilities on the face of the balance sheet, accompanied by enhanced qualitative and quantitative disclosures in the notes to the financial statements. The Update is generally effective for public business entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is in the early stages of its implementation assessment, which includes identifying the population of the Company's leases that are within the scope of the new guidance and gathering all key lease data that will facilitate application of the new accounting requirements.

ASU 2014-09, Revenue From Contracts With Customers (Topic 606), ASU 2015-14 Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date, ASU 2016-08 Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU 2016-10 Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, ASU 2016-11 Revenue Recognition (Topic 605) and Derivatives ad Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting, ASU 2016-12 Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, and ASU 2016-20 Revenue from Contracts with Customers (Topic 606): Technical Corrections and Improvements to Topic 606. The FASB amended existing guidance related to revenue from contracts with customers, superseding and replacing nearly all existing revenue recognition guidance, including industry-specific guidance, establishing a new control-based revenue recognition model, changing the basis for deciding when revenue is recognized over time or at a point in time, providing new and more detailed guidance on specific topics and expanding and improving disclosures about revenue. In addition, this guidance specifies the accounting for some costs to obtain or fulfill a contract with a customer. The amendments are effective for public entities for annual reporting periods beginning after December 15, 2017. A substantial portion of the Company’s revenues represent interest and fee income generated from financial instruments such as loans and investment securities. Revenues generated from financial instruments such as these are not within the scope of this guidance. Revenue sources that are within the scope of this guidance include service charges and fees on deposit accounts. The Company is in the process of reviewing non-interest income revenue sources to determine if they are within the scope of the new guidance. The Company does not expect the adoption will have a significant impact on its Consolidated Financial Statements.

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, 2016 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.

Certain Acquired Loans–As part of business acquisitions, the Bank acquires certain loans that have shown evidence of credit deterioration since origination. These acquired loans are recorded at the allocated fair value, such that there is no carryover of the seller’s allowance for loan losses. Such acquired loans are accounted for individually. The Bank estimates the amount and timing of expected cash flows for each purchased loan, and the expected cash flows in excess of the allocated fair value is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan’s contractual principal and interest over expected cash flows is not recorded (non-accretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded through the allowance for loan losses. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income.

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 November 30 as the date 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–The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

Business Combinations [Abstract]

Acquisitions

Acquisitions

The Company accounted for the following transactions under the acquisition method of accounting, which requires purchased assets and liabilities assumed to be recorded at their respective fair values at the date of acquisition. The Company determined the fair value of the loans, core deposit intangible, securities and deposits with the assistance of third party valuations.

Heritage Oaks Bancorp Acquisition

Effective as of April 1, 2017, the Company completed the acquisition of Heritage Oaks Bancorp ("HEOP"), the holding company of Heritage Oaks Bank, a Paso Robles, California based state-chartered bank (“Heritage Oaks Bank”) with $2.0 billion in total assets, $1.4 billion in gross loans and $1.7 billion in total deposits at March 31, 2017. Heritage Oaks Bank operates branches within San Luis Obispo and Santa Barbara Counties and a loan production office in Ventura County.

Pursuant to the terms of the merger agreement, each outstanding share of HEOP common stock was converted into the right to receive 0.3471 shares of corporate common stock. The value of the total deal consideration was approximately $465 million, which included approximately $3.9 million of aggregate cash consideration payable to holders of Heritage Oaks share-based compensation awards, and the issuance of 11,959,022 shares of the Corporation's common stock, which had a value of $38.55 per share, which was the closing price of the Corporation's common stock on March 31, 2017, the last trading day prior to the consummation of the acquisition.

Goodwill in the amount of $269 million was recognized in the HEOP 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.

Security California Bancorp Acquisition

On January 31, 2016, the Company completed its acquisition of Security California Bancorp (“SCAF”), whereby we acquired $714 million in total assets, $456 million in loans and $637 million in total deposits. Under the terms of the merger agreement, each share of SCAF common stock was converted into the right to receive 0.9629 shares of the Corporation’s common stock. The value of the total deal consideration was $120 million, which includes $788,000 of aggregate cash consideration to the holders of SCAF stock options and the issuance of 5,815,051 shares of the Corporation’s common stock, valued at $119 million based on a closing stock price of $20.53 per share on January 29, 2016.

SCAF was the holding company of Security Bank of California, a Riverside, California, based state-chartered bank with six branches located in Riverside County, San Bernardino County and Orange County.

Goodwill in the amount of $51.7 million was recognized in the SCAF 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 fair values are estimates and are subject to adjustment for up to one year after the merger date or when additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. In the second quarter of 2016, the Company made a $146,000 adjustment to fixed assets and goodwill. As of March 31, 2017, the Company finalized its fair values with this acquisition.

Unrealized gains and losses on investment securities available-for-sale are recognized in stockholders’ equity as accumulated other comprehensive income or loss. At September 30, 2017, the Company had an accumulated other comprehensive income of $4.2 million, or $2.5 million net of tax, compared to an accumulated other comprehensive loss of $4.7 million, or $2.7 million net of tax, at December 31, 2016.

At September 30, 2017, mortgage-backed securities ("MBS ") with an estimated par value of $62.4 million and a fair value of $64.2 million were pledged as collateral for the Bank’s three repurchase agreements, which totaled $28.5 million, and homeowner’s association (“HOA”) reverse repurchase agreements, which totaled $18.5 million.

At December 31, 2016, MBS with an estimated par value of $63.6million and a fair value of $65.3 million were pledged as collateral for the Bank’s three repurchase agreements, which totaled $28.5 million, and HOA reverse repurchase agreements, which totaled $21.5 million.

At September 30, 2017 and December 31, 2016, there were not holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of shareholders' 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.

The Company did not realize any OTTI recoveries or losses for the three months ended September 30, 2017 and June 30, 2017. However, the Company did realize an OTTI recovery of $2,000 for the three months ended September 30, 2016, which relates to investment income from a previously charge-off investment. A $207,000 OTTI was taken in the first quarter of 2016, related to a CRA investment purchased in June of 2014 with a par value of $50, and a book value of $500,000. In March 2016, the shareholders of the investment voted to approve a sale of the institution at a per share acquisition price less the Bank's book value, and the sale closed in July 2016. The Company is currently waiting to receive the proceeds for its outstanding shares. As a result, the Company's current holdings were written down and the loss recognized.

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.

(1) Secured by real estate.

(2) Includes second trust deeds.

(3) Total gross loans held for investment for September 30, 2017 are net of the unaccreted fair value purchase discounts of $21.6 million.

From time to time, we may purchase or sell loans in order to manage concentrations, maximize interest income, change risk profiles, improve returns and generate liquidity.

The Company makes residential and commercial loans held for investment to customers located primarily in California. Consequently, the underlying collateral for our loans and a borrower’s ability to repay may be impacted unfavorably by adverse changes in the economy and real estate market in the region.

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 $269.1 million for secured loans and $161.5 million for unsecured loans at September 30, 2017. At September 30, 2017, the Bank’s largest aggregate outstanding balance of loans to one borrower was $45.0 million of secured credit.

Purchased Credit Impaired Loans

The Company has acquired loans as part of its acquisitions of Canyon National Bank in 2011, Palm Desert National Bank in 2012, Independence Bank in 2015, Security Bank of California in 2016 and Heritage Oaks Bank in 2017 for which there was, at acquisition, evidence of deterioration of credit quality since origination and for which it was probable, at acquisition, that all contractually required payments would not be collected. The carrying amount of those loans is as follows:

	September 30, 2017		December 31, 2016
	(dollars in thousands)
Business loans:
Commercial and industrial	$	2,870	$	2,586
Commercial owner occupied	3,019		491
SBA	334		—
Real estate loans:
Commercial non-owner occupied	1,303		1,088
Multi-family	226		—
One-to-four family	257		1
Construction/Land	973		—
Other loans	221		393
Total purchase credit impaired	$	9,203	$	4,559

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 September 30, 2017, the Company had $9.2 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 three months ended September 30, 2017, June 30, 2017 and September 30, 2016 and for the nine months ended September 30, 2017 and 2016:

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, or 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. All loans are generally charged-off at such 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.

The following table provides additional detail on the components of impaired loans at the period end indicated:

	September 30, 2017		December 31, 2016
	(dollars in thousands)
Nonaccruing loans	$	515	$	1,141
Accruing loans	878		—
Total impaired loans	$	1,393	$	1,141

When loans are placed on nonaccrual status all accrued interest is reversed from earnings. 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 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 collection of interest. The Company had impaired loans on nonaccrual status of $515,000 at September 30, 2017 and $1.1 million at December 31, 2016. The Company had no loans 90 days or more past due and still accruing at September 30, 2017 and December 31, 2016.

At September 30, 2017, the Company had a recorded investment in two TDR loans totaling $878,500. The modification of the terms of the first relationship, totaling $775,500, included the restructuring of three loans related to one borrower into one loan and an extension of the maturity to six years. The modification of the terms of the second relationship, totaling $103,000, included the restructuring of two loans related to one borrower into one loan and an extension of the maturity to three years. There were no TDRs at December 31, 2016. In addition, the Company had $41,000 in consumer mortgage loans collateralized by residential real estate property for which formal foreclosure proceedings were in process as of September 30, 2017 and December 31, 2016.

Concentration of Credit Risk

As of September 30, 2017, 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 and commercial owner occupied real estate and business loans. The Bank maintains policies approved by the Bank’s Board of Directors (the “Bank Board”) that address these concentrations and continues to diversify 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.

Credit Quality and Credit Risk Management

The Company’s credit quality is maintained and credit risk managed 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 minimum and 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 Board. The Bank’s seasoned 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 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 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 by the Company’s Credit and Portfolio Review committee, and are reviewed annually by an independent third-party, 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 which contain no well-defined deficiency or weakness.

• 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 portfolio managers also manage loan performance risks, collections, workouts, bankruptcies and foreclosures. Loan performance risks are mitigated by our portfolio managers acting promptly and assertively to address problem credits when they are identified. Collection efforts are commenced 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 or 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 the full amount of the Company’s recorded investment in the loan is no longer collectable. The Company typically continues to obtain or confirm 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 by the Company’s internal risk grading as of 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 credit losses inherent in the remainder of the loan portfolio. The ALLL is prepared in accordance with the historical loss method, 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 (replacing prior period's interval ranging from 8 to 87 months) with the loss emergence period extending from 1 year to 1.4 years. The aforementioned enhancements did not materially impact the allowance balance at September 30, 2017. 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 management’s judgment, taking into consideration the specific characteristics of the Bank’s portfolio and analysis of results from a select group of the Company’s peers.

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 three and nine months ended for the periods indicated:

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”) 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 bear interest at an annual fixed rate of 5.75%, and the first interest payment on the Notes occurred on March 3, 2015, and will continue to be payable semiannually each March 3 and September 3 until September 3, 2024. The Notes can only be redeemed, partially or in whole, prior to the maturity date if the notes do not constitute Tier 2 Capital (for purposes of capital adequacy guidelines of the Board of Governors of the Federal Reserve). Outstanding principal and accrued and unpaid 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. These ratings were reaffirmed by KBRA on October 27, 2017.

In March 2004, the Corporation issued $10.3 million of Floating Rate Junior Subordinated Deferrable Interest Debentures (the “Subordinated Debentures”) to PPBI Trust I, which funded the payment of $10 million of Floating Rate Trust Preferred Securities (“Trust Preferred Securities”) issued by PPBI Trust I in March 2004 due April 7, 2034. The net proceeds from the offering of Trust Preferred Securities were contributed as capital to the Bank to support further growth. Interest is payable quarterly on the Subordinated Debentures at three-month LIBOR plus 2.75% per annum, for an effective rate of 4.05% per annum as of September 30, 2017.

On April 1, 2017, as part of the Heritage Oaks 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 3.02% per annum as of September 30, 2017. At September 30, 2017, the carrying value of these debentures was $3.9 million, which reflects purchase accounting fair value adjustments of $1.3 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 September 30, 2017, the carrying value of Mission Community Capital Trust I and Santa Lucia Bancorp (CA) Capital Trust were $2.8 million and $3.7 million, respectively, which reflects purchase accounting fair value adjustments of $332,000 and $1.4 million, respectively. Interest is payable quarterly at three-month LIBOR plus 2.95% per annum, for an effective rate of 4.25% per annum as of September 30, 2017 for Mission Community Capital Trust I. Interest is payable quarterly at three-month LIBOR plus 1.48% per annum, for an effective rate of 2.78% per annum as of September 30, 2017 for Santa Lucia Bancorp (CA) Capital Trust. These three debentures are callable by the Corporation at par.

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 as a component of the Company’s liabilities.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share excludes dilution and is computed by dividing net income or loss available to common stockholders by the weighted average number of common shares outstanding for the period, excluding common shares in treasury. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted from the issuance of common stock that would then share in earnings and excludes common shares in treasury. Stock options exercisable for shares of common stock are excluded from the computation of diluted earnings per share if they are anti-dilutive due to their exercise price exceeding the average market price during the period.

The impact of stock options which are anti-dilutive are excluded from the computations of diluted earnings per share. The dilutive impact of these securities could be included in future computations of diluted earnings per share if the market price of the common stock increases. The following table sets forth the weighted average number of stock options excluded for the periods indicated:

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability 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, and for estimating the fair value of financial assets and financial liabilities not recorded 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. Therefore, for substantially all financial instruments, the fair value estimates presented herein are not necessarily indicative of the amounts the Company could have realized in a sales transaction at September 30, 2017, June 30, 2017 and September 30, 2016.

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. The following is a description of both the general and specific valuation methodologies used for certain instruments measured at fair value, as well as the general classification of these instruments pursuant to the valuation hierarchy.

Cash and due from banks – The carrying amounts of cash and short-term instruments approximate fair value due to the liquidity of these instruments.

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.

FHLB, FRB, Other Stock – Due to restrictions placed on transferability, it is not practical to determine the fair value of the stock.

Loans Held for Sale — The fair value of loans held for sale is estimated based upon binding contracts and quotes from third party investors resulting in a Level 2 classification.

Loans Held for Investment — The fair value of loans, other than loans on nonaccrual status, was estimated by discounting the remaining contractual cash flows using the estimated current rate at which similar loans would be made to borrowers with similar credit risk characteristics and for the same remaining maturities, reduced by deferred net loan origination fees and the allocable portion of the allowance for loan losses. Accordingly, in determining the estimated current rate for discounting purposes, no adjustment has been made for any change in borrowers’ credit risks since the origination of such loans. Rather, the allocable portion of the allowance for loan losses is considered to provide for such changes in estimating fair value. As a result, this fair value is not necessarily the value which would be derived using an exit price. These loans are included within Level 3 of the fair value hierarchy.

Impaired loans and OREO– Impaired loans and OREO assets are recorded at the fair value less estimated costs to sell at the time of foreclosure. The fair value of impaired loans and OREO assets are generally based on recent real estate appraisals adjusted for estimated selling costs. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value.

Deposit Accounts and Short-term Borrowings — The amounts payable to depositors for demand, savings, and money market accounts, and short-term borrowings are considered to approximate fair value. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities using a discounted cash flow calculation. Interest-bearing deposits and borrowings are included within Level 2 of the fair value hierarchy.

Term FHLB Advances and Other Long-term Borrowings— The fair value of long term borrowings is determined using rates currently available for similar borrowings with similar credit risk and for the remaining maturities and are classified as Level 2.

Subordinated Debentures – The fair value of subordinated debentures is estimated by discounting the balance by the current three-month LIBOR rate plus the current market spread. The fair value is determined based on the maturity date as the Company does not currently have intentions to call the debenture and is classified as Level 2.

Accrued Interest Receivable/Payable – The carrying amounts of accrued interest receivable and accrued interest payable are deemed to approximate fair value.

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.

The fair value estimates presented herein are based on pertinent information available to management as of the periods indicated.

The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

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 non-accrual loans for which it has reduced the principal balance to the value of the underlying collateral less the anticipated selling cost. As such, the Company records impaired loans as Level 3. At September 30, 2017, 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 fair value of impaired loans and other real estate owned were determined using Level 3 assumptions, and represents impaired loan and other real estate loan 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure

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. At September 30, 2017, the Company had swaps with matched terms with an aggregate notional amount of $59.0 million and a fair value of $0.6 million. 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 non-interest 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 nine months ended September 30, 2017, 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 September 30, 2017 are not designated as hedging instruments.

The following tables summarize the Company's derivative instruments, included in "other assets" and "other liabilities" in the consolidated statements of financial condition. The Company's derivative instruments were acquired as part of the HEOP acquisition, and the Company did not have any at December 31, 2016:

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.

Pacific Premier Bancorp, Inc. and Plaza Bancorp

On August 9, 2017, the Company announced that it had entered into an agreement to acquire Plaza Bancorp (PLZZ.OTC) ("Plaza"), the holding company of Plaza Bank, a California-chartered banking corporation headquartered in Irvine, California, with seven branches located in Irvine, Manhattan Beach, El Segundo, Pasadena, Montebello, San Diego, California, and Las Vegas, Nevada.

The acquisition was completed on November 1, 2017, whereby we acquired $1.3 billion in total assets, $1.1 billion in loans and $1.1 billion in total deposits. Under the terms of the merger agreement, each share of Plaza common stock was converted into the right to receive 0.2000 shares of Company common stock. Pursuant to such terms, the Company will issue approximately 6,049,447 shares of the Company's Common Stock valued at $40.40 per share, which was the closing price of the Company's Common Stock on October 31, 2017, the last trading day prior to the consummation of the Merger. The value of the total transaction consideration was approximately $251 million, which included approximately $6.5 million in aggregate cash for fractional shares and consideration payable to holders of Plaza options and Plaza warrants in connection with the closing of the Merger.

The Company expects to record goodwill arising from the acquisition consisting largely of synergies and cost savings resulting from combining the operations of the companies. The amount of goodwill is not expected to be deductible for tax purposes. The fair value of intangible assets and acquired assets and liabilities will be determined as of the acquisition date but are still being evaluated as of the date of these financial statements.

Recently Issued Accounting Pronouncements

Accounting Standards Adopted in 2017

In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Accounting. The amendments simplify several aspects of the accounting for share-based payment award transactions, including accounting for excess tax benefits and tax deficiencies, classifying excess tax benefits on the statement of cash flows, accounting for forfeitures, classifying awards that permit share repurchases to satisfy statutory tax-withholding requirements and classifying tax payments on behalf of employees on the statement of cash flows. For public business entities, the amendment is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is permitted for any organization in any interim or annual period. As a result of the adoption of ASU 2016-09, the Company began recognizing the tax effects of exercised or vested awards as discrete items in the reporting period in which they occur, resulting in a $355,000 and a $2.0 million tax benefit to the Company for the three and nine months ended September 30, 2017, respectively.

In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships. The amendments clarify that a change in the counterparty to a derivative instrument designated as a hedging instrument does not, in and of itself, require designation of that hedging relationship provided that all other hedge accounting criteria remain the same. The Update is effective for public business entities for fiscal years beginning after December 31, 2016, including interim periods within those years. The adoption of this standard did not have a material effect on the Company's operating results or financial condition.

Recent Accounting Guidance Not Yet Effective

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. The amendments provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. Modification accounting will apply unless all of the following are the same immediately before and after the modification:

• The award’s fair value – or calculated value or intrinsic value, if an alternative method is used. If the modification does not affect any inputs to the valuation of the award, estimating the value immediately before and after the modification is not required.

• The award’s vesting provisions

• The award’s classification as an equity instrument or a liability instrument

The Update is effective for all entities for fiscal years beginning after December 15, 2017, including interim periods within those years. The amendments should be applied prospectively to awards modified on or after the effective date. The adoption of this standard will not material effect the Company's operating results or financial condition, as historically the Company has not modified share-based awards.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For public business entities, the amendment is effective for annual periods beginning after December 15, 2019 and interim period within those annual periods. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures. The Company is in the process of compiling key data elements and considering software models that will meet the requirements of the new guidance.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new standard is being issued to increase the transparency and comparability around lease obligations. Previously unrecorded off-balance sheet obligations will now be brought more prominently to light by presenting lease liabilities on the face of the balance sheet, accompanied by enhanced qualitative and quantitative disclosures in the notes to the financial statements. The Update is generally effective for public business entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is in the early stages of its implementation assessment, which includes identifying the population of the Company's leases that are within the scope of the new guidance and gathering all key lease data that will facilitate application of the new accounting requirements.

ASU 2014-09, Revenue From Contracts With Customers (Topic 606), ASU 2015-14 Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date, ASU 2016-08 Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU 2016-10 Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, ASU 2016-11 Revenue Recognition (Topic 605) and Derivatives ad Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting, ASU 2016-12 Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, and ASU 2016-20 Revenue from Contracts with Customers (Topic 606): Technical Corrections and Improvements to Topic 606. The FASB amended existing guidance related to revenue from contracts with customers, superseding and replacing nearly all existing revenue recognition guidance, including industry-specific guidance, establishing a new control-based revenue recognition model, changing the basis for deciding when revenue is recognized over time or at a point in time, providing new and more detailed guidance on specific topics and expanding and improving disclosures about revenue. In addition, this guidance specifies the accounting for some costs to obtain or fulfill a contract with a customer. The amendments are effective for public entities for annual reporting periods beginning after December 15, 2017. A substantial portion of the Company’s revenues represent interest and fee income generated from financial instruments such as loans and investment securities. Revenues generated from financial instruments such as these are not within the scope of this guidance. Revenue sources that are within the scope of this guidance include service charges and fees on deposit accounts. The Company is in the process of reviewing non-interest income revenue sources to determine if they are within the scope of the new guidance. The Company does not expect the adoption will have a significant impact on its Consolidated Financial Statements.

Certain Acquired Loans

Certain Acquired Loans–As part of business acquisitions, the Bank acquires certain loans that have shown evidence of credit deterioration since origination. These acquired loans are recorded at the allocated fair value, such that there is no carryover of the seller’s allowance for loan losses. Such acquired loans are accounted for individually. The Bank estimates the amount and timing of expected cash flows for each purchased loan, and the expected cash flows in excess of the allocated fair value is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan’s contractual principal and interest over expected cash flows is not recorded (non-accretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded through the allowance for loan losses. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income.

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 November 30 as the date 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–The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

Fair Value Measurement

Cash and due from banks – The carrying amounts of cash and short-term instruments approximate fair value due to the liquidity of these instruments.

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.

FHLB, FRB, Other Stock – Due to restrictions placed on transferability, it is not practical to determine the fair value of the stock.

Loans Held for Sale — The fair value of loans held for sale is estimated based upon binding contracts and quotes from third party investors resulting in a Level 2 classification.

Loans Held for Investment — The fair value of loans, other than loans on nonaccrual status, was estimated by discounting the remaining contractual cash flows using the estimated current rate at which similar loans would be made to borrowers with similar credit risk characteristics and for the same remaining maturities, reduced by deferred net loan origination fees and the allocable portion of the allowance for loan losses. Accordingly, in determining the estimated current rate for discounting purposes, no adjustment has been made for any change in borrowers’ credit risks since the origination of such loans. Rather, the allocable portion of the allowance for loan losses is considered to provide for such changes in estimating fair value. As a result, this fair value is not necessarily the value which would be derived using an exit price. These loans are included within Level 3 of the fair value hierarchy.

Impaired loans and OREO– Impaired loans and OREO assets are recorded at the fair value less estimated costs to sell at the time of foreclosure. The fair value of impaired loans and OREO assets are generally based on recent real estate appraisals adjusted for estimated selling costs. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value.

Deposit Accounts and Short-term Borrowings — The amounts payable to depositors for demand, savings, and money market accounts, and short-term borrowings are considered to approximate fair value. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities using a discounted cash flow calculation. Interest-bearing deposits and borrowings are included within Level 2 of the fair value hierarchy.

Term FHLB Advances and Other Long-term Borrowings— The fair value of long term borrowings is determined using rates currently available for similar borrowings with similar credit risk and for the remaining maturities and are classified as Level 2.

Subordinated Debentures – The fair value of subordinated debentures is estimated by discounting the balance by the current three-month LIBOR rate plus the current market spread. The fair value is determined based on the maturity date as the Company does not currently have intentions to call the debenture and is classified as Level 2.

Accrued Interest Receivable/Payable – The carrying amounts of accrued interest receivable and accrued interest payable are deemed to approximate fair value.
