Overview

We are a California-based bank holding company incorporated in 1997 in the State of Delaware and a registered 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. The Bank was founded in 1983 as a state-chartered thrift and subsequently converted to a federally-chartered thrift in 1991. The Bank converted to a California-chartered commercial bank and became a member of the Federal Reserve System in March of 2007. The Bank is a member of the Federal Home Loan Bank of San Francisco (“FHLB”), which is a member bank of the Federal Home Loan Bank System. The Bank’s deposit accounts are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to the maximum amount currently allowable under federal law. The Bank is currently subject to examination and regulation by the Federal Reserve Bank (“FRB”), the California Department of Business Oversight-Division of Financial Institutions (“DBO”), the Consumer Financial Protection Bureau (“CFPB”) and the FDIC.

We are a growth company keenly focused on building shareholder value through consistent earnings and creating franchise value. Our growth is derived both organically and through acquisitions of financial institutions and lines of business that complement commercial business banking strategy. The Bank’s primary target market is small and middle market businesses.

We primarily conduct business throughout California from our 44 full-service depository branches in the counties of Orange, Los Angeles, Riverside, San Bernardino, San Diego, San Luis Obispo and Santa Barbara, California as well as markets in Pima and Maricopa Counties, Arizona, Clark County, Nevada and Clark County, Washington.

We provide banking services within our targeted markets to businesses, including the owners and employees of those businesses, professionals, real estate investors and non-profit organizations. Additionally, we provide certain banking services nationwide. We provide customized cash management, electronic banking services and credit facilities to Homeowners’ Associations (“HOA”) and HOA management companies nationwide. We provide U.S. Small Business Administration (“SBA”) loans nationwide, which provide entrepreneurs and small business owners access to loans needed for working capital and continued growth. In addition, we offer loans and

other services nationwide to experienced owner-operator franchisees in the quick service restaurant (“QSR”) industry.

Through our branches and our internet website at www.ppbi.com, we offer a broad array of deposit products and services, including checking, money market and savings accounts, cash management services, electronic banking services, and on-line bill payment. We also offer a wide array of loan products, such as commercial business loans, lines of credit, SBA loans, commercial real estate (“CRE”) loans, agribusiness loans, home equity lines of credit, construction loans, farmland and consumer loans. At December 31, 2018, we had consolidated total assets of $11.49 billion, net loans of $8.80 billion, total deposits of $8.66 billion, and consolidated total stockholders’ equity of $1.97 billion. At December 31, 2018, the Bank was considered a “well-capitalized” financial institution for regulatory capital purposes.

Recent Acquisition

Grandpoint Capital, Inc. Acquisition — Effective as of July 1, 2018, the Company completed the acquisition of Grandpoint Capital, Inc. (“Grandpoint”), the holding company of Grandpoint Bank, a California-chartered bank headquartered in Los Angeles, California, pursuant to the terms of a definitive agreement entered into by the Corporation and Grandpoint on February 9, 2018. As a result of the Grandpoint acquisition, the Bank acquired approximately $3.05 billion in total assets, $2.40 billion in gross loans and $2.51 billion in total deposits as of the date of the acquisition.

Pursuant to the terms of the definitive agreement, each outstanding share of Grandpoint voting common stock and Grandpoint non-voting common stock was converted into the right to receive 0.4750 shares of the Corporation’s common stock. The value of the total transaction consideration was approximately $601.2 million after approximately $28.1 million in aggregate cash consideration payable to holders of Grandpoint share-based compensation awards by Grandpoint. The transaction consideration represented the issuance of 15,758,089 shares of the Corporation’s common stock, valued at $38.15 per share, which was the closing price of the Corporation’s common stock on June 29, 2018, the last trading day prior to the consummation of the acquisition.

The Grandpoint acquisition was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed and consideration exchanged were recorded at estimated fair value on the acquisition date, in accordance with Financial Accounting Standards Board (“FASB”) ASC Topic 805, Business Combinations. 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 subject to refinement for up to one year after the closing date of acquisition as additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. Fair value adjustments will be finalized no later than July 2019.

5

The integration and system conversion of Grandpoint was completed in October 2018.

For additional information regarding the acquisition of Grandpoint, see “Note 26. Acquisitions”of the Notes to the Consolidate Financial Statements contained in “Item 8. Financial Statements and

Supplementary Data.”

Our Strategic Plan

Our strategic plan is focused on generating organic growth through our high performing sales culture. Additionally, we seek to grow through mergers and acquisitions of banks and the acquisition of lines of business that complement our business banking strategy.

Our two key operating strategies are summarized as follows:

• Expansion through Organic Growth.  Over the past several years, we have developed a high performing sales culture that places a premium on business bankers who have the ability to consistently generate business with new and existing clients. Business unit managers that possess in-depth product knowledge and expertise in their respective lines of business systematically manage the business development efforts through the use of sales and relationship management technology tools.

• Expansion through Acquisitions.  Our acquisition strategy is twofold: first, we seek to acquire whole banks within and contiguous to the State of California to expand geographically and/or to consolidate in our existing markets; and second, we seek to acquire lines of business that will complement our existing business banking strategy. We have completed ten acquisitions since 2010, the first two of which were FDIC-assisted transactions and all other bank transactions were open bank, arm’s length negotiated transactions: Canyon National Bank (“CNB”) (geographic expansion, closed February 2011), Palm Desert National Bank (“PDNB”) (in market consolidation, closed April 2012), First Associations Bank (“FAB”) (nationwide HOA line of business, closed March 2013), San Diego Trust Bank (“SDTB”) (geographic expansion, closed June 2013), Infinity Franchise Holdings, LLC and Infinity Franchise Capital (collectively, “Infinity”) (nationwide lender to franchisees in the QSR industry, closed January 2014), Independence Bank (“IDPK”) (geographic expansion, closed January 2015), Security Bank of California (“SCAF”) (geographic expansion, closed January 2016), Heritage Oaks Bancorp (“HEOP”) (geographic expansion, closed April 2017), Plaza Bancorp (“PLZZ”) (geographic expansion, closed November 2017) and Grandpoint (geographic expansion, closed July 2018). We intend to continue to pursue acquisitions of open banks and other non-depository businesses that meet our criteria, though there can be no assurances that we will identify or consummate any such acquisitions, or should we do so, that any or all of those acquisitions will produce the intended results.

Lending Activities

General.  In 2018, we maintained our commitment to a high level of credit quality in our lending activities. Our core lending business continues to focus on meeting the financial needs of local businesses and their owners. To that end, the Company offers a full complement of flexible and structured loan products tailored to meet the diverse needs of our small and middle market commercial customers.

During 2018, we made or purchased loans to borrowers secured by real property and business assets located principally in California, our primary market area, as well as in certain markets in the states of Arizona, Nevada, and Washington where we also have depository and lending offices. We made select loans, primarily QSR franchise loans, SBA guaranteed loans and loans to HOAs, throughout the United States. We emphasize relationship lending and focus on generating loans with customers who also maintain full depository relationships with us. These efforts assist us in establishing and expanding depository relationships consistent with the Company’s strategic direction. We maintain internal lending limits below our $526.0 million legal lending limit for secured loans and $315.0 million legal lending limit for unsecured loans as of December 31, 2018. At December 31, 2018, the Bank’s largest aggregate outstanding balance of loans to one borrower was $131.0 million of secured credit. Historically, we have managed loan concentrations by selling certain loans, primarily commercial non-owner occupied CRE and multi-family residential loan production. We have also focused on selling the guaranteed portion of SBA loans due to the historically attractive premiums in the market, which gains on sale increase our noninterest income. Other types of loan sales remain a strategic option for us.

During 2018, we generated $2.35 billion of new loan commitments and $1.62 billion of new loan funding, including $533.2 million and $201.4 million of commercial and industrial (“C&I”) loans, respectively, $283.7 million and $219.5 million of franchise loans, respectively, $315.4 million and $312.8 million of owner occupied CRE loans, respectively, $139.8 million and $137.1 million of SBA loans, respectively, $59.7 million and $38.1 million of agribusiness loans, respectively, $372.3 million and $370.3 million of non-owner occupied CRE loans, respectively, $220.5 million and $209.7 million of multi-family real estate loans, respectively, $46.0 million and $32.4 million of one-to-four family real estate loans, respectively, $326.2 million and $57.6 million of construction loans, respectively, $20.4 million and $16.8 million of farmland loans, respectively, $12.0 million and $10.5 million of land loans, respectively, and $24.0 million and $10.7 million of consumer loans. During the same period, the acquisition of Grandpoint added $2.40 billion of loans in the third quarter of 2018 before fair value adjustments. At December 31, 2018, we had $8.85 billion in total gross loans held for investment outstanding.

Commercial and Industrial Lending.  We originate C&I loans secured by business assets including inventory, receivables, and machinery and equipment to businesses located in our primary market areas. Loan types include revolving lines of credit, term loans, seasonal loans and loans secured by liquid collateral such as cash deposits or marketable securities. HOA credit facilities are included in C&I loans. We also issue letters of credit on behalf of our customers, backed by deposits or other collateral with the Company. At December 31, 2018, C&I loans totaled $1.36 billion, constituting 15.4% of our gross loans held for investment. At December 31, 2018, we had commitments to extend additional credit on C&I loans of $1.12 billion.

Franchise Lending. We originate loans to franchises in the QSR industry nationwide, including financing for equipment, real estate, new store development, remodeling, refinancing, acquisition and partnership restructuring. At December 31, 2018, franchise loans totaled $765.4 million, constituting 8.7% of our gross loans held for investment.

Commercial Owner-Occupied Business Lending.  We originate and purchase loans secured by owner-occupied CRE, such as small office and light industrial buildings, and mixed-use commercial properties located in our primary market areas. We also make loans secured by special purpose properties, such as gas stations and churches. Pursuant to our underwriting policies, owner-occupied CRE loans may be made in amounts of up to 80% of the lesser of the appraised value or the purchase price of the collateral property. Loans are generally made for terms up to 25 years with amortization periods up to 25 years. At December 31, 2018, we had $1.68 billion of owner-occupied CRE secured loans, constituting 19.0% of our gross loans held for investment. 

7

SBA Lending.  We are approved to originate loans under the SBA’s Preferred Lenders Program (“PLP”). The PLP lending status affords us a higher level of delegated credit autonomy, translating to a significantly shorter time-line from application to funding, which is critical to our marketing efforts. We originate loans nationwide under the SBA’s 7(a), SBAExpress, International Trade and 504 loan programs, in conformity with SBA underwriting and documentation standards. The guaranteed portion of the 7(a) loans is typically sold on the secondary market. At December 31, 2018, we had $193.9 million of SBA loans, constituting 2.2% of our gross loans held for investment.

Agribusiness and Farmland. We originate loans to the agricultural community to fund seasonal production and longer term investments in land, buildings, equipment, crops and livestock. Agribusiness loans are for the purpose of financing agricultural production, specifically crops and livestock. Farmland loans include all land known to be used or usable for agricultural purposes, such as crop and livestock production, and is secured by the land and improvements thereon. At December 31, 2018, agribusiness loans totaled $138.5 million, constituting 1.6% of our gross loans held for investment. At December 31, 2018, we had $150.5 million of farmland loans, constituting 1.7% of our gross loans held for investment.

Commercial Non-Owner Occupied Real Estate Lending.  We originate and purchase loans that are secured by CRE, such as retail centers, small office and light industrial buildings, and mixed-use commercial properties located in our primary market areas that are not occupied by the borrower. We also make loans secured by special purpose properties, such as hotels and self-storage facilities. Pursuant to our underwriting practices, non-owner occupied CRE loans may be made in amounts up to 75% of the lesser of the appraised value or the purchase price of the collateral property. We consider the net operating income of the property and typically require a stabilized debt service coverage ratio of at least 1.20:1, based on the qualifying loan interest rate. Loans are generally made for terms from 10 years up to 25 years, with amortization periods up to 25 years. At December 31, 2018, we had $2.00 billion of non-owner occupied CRE secured loans, constituting 22.6% of our gross loans held for investment. 

Multi-family Residential Lending.  We originate and purchase loans secured by multi-family residential properties (five units and greater) located in our primary market areas. Pursuant to our underwriting practices, multi-family residential loans may be made in an amount up to 75% of the lesser of the appraised value or the purchase price of the collateral property. In addition, we generally require a stabilized minimum debt service coverage ratio of at least 1.15:1, based on the qualifying loan interest rate. Loans are made for terms of up to 30 years with amortization periods up to 30 years. At December 31, 2018, we had $1.54 billion of multi-family real estate secured loans, constituting 17.4% of our gross loans held for investment. 

One-to-Four Family Real Estate Lending.  Although we do not originate traditional consumer single family residential mortgages, we have acquired single family residential mortgages through our bank acquisitions. Our portfolio of one-to-four family loans at December 31, 2018 totaled $356.3 million, constituting 4.0% of our gross loans held for investment, of which $306.3 million consists of loans secured by first liens on real estate and $50.0 million consists of loans secured by second or junior liens on real estate.

Construction Lending.  We originate loans for the construction of 1-4 family homes, multi-family residences and CRE properties in our market areas. We concentrate our1-4 family construction lending on single homes and small infill projects in established neighborhoods where there is not abundant land available for development. Multi-family and commercial construction loans are made to experienced developers for projects with strong market demand. Pursuant to our underwriting practices, construction loans may be made in an amount up to the lesser of 80% of the completed value of or 85% of the cost to build the collateral property. Loans are made solely for the term of construction, generally less than 24 months. We require that the owner’s equity is injected prior to the funding of the loan. At December 31, 2018, construction loans totaled $523.6 million, constituting 5.9% of our gross loans, and we had commitments to extend additional construction credit of $420.7 million.

8

Land Loans.  We occasionally originate land loans located in our primary market areas for the purpose of facilitating the ultimate construction of a home or commercial building. We do not originate loans to facilitate the holding of land for speculative purposes. At December 31, 2018, land loans totaled $46.6 million, constituting 0.5% of our gross loans.

Consumer Loans.  We originate a limited number of consumer loans, generally for existing banking customers only, which consist primarily of small balance personal unsecured loans and savings account secured loans. Before we make a consumer loan, we assess the applicant’s ability to repay the loan and, if applicable, the value of the collateral securing the loan. At December 31, 2018, we had $89.4 million in consumer loans, which represented less than 1.0% of our gross loans.

Sources of Funds

General.  Deposits, loan repayments and prepayments, and cash flows generated from operations and borrowings are the primary sources of the Company’s funds for use in lending, investing and other general purposes.

Deposits.  Deposits represent our primary source of funds for our lending and investing activities. The Company offers a variety of deposit accounts with a range of interest rates and terms. The deposit accounts are offered through our 44 full depository branch network in California and Nevada, including our Irvine, California branch, which serves our nationwide HOA Banking unit located in Dallas, Texas. The Company’s deposits consist of checking accounts, money market accounts, passbook savings, and certificates of deposit. The flow of deposits is influenced significantly by general economic conditions, changes in money market rates, prevailing interest rates and competition. The terms of the fixed-rate certificates of deposit offered by the Company vary from three months to five years. Specific terms of an individual account vary according to the type of account, the minimum balance required, the time period funds must remain on deposit and the interest rate, among other factors. Total deposits at December 31, 2018 were $8.66 billion, compared to $6.09 billion at December 31, 2017. At December 31, 2018, certificates of deposit constituted 16.3% of total deposits, compared to 17.8% at December 31, 2017. At December 31, 2018, we had $1.11 billion of certificate of deposit accounts maturing in one year or less.

We primarily rely on customer service, sales and marketing efforts, business development, cross selling of deposit products to loan customers, and long-standing relationships with customers to attract and retain local deposits. However, market interest rates and rates offered by competing financial institutions significantly affect the Company’s ability to attract and retain deposits. Additionally, from time to time, we will utilize both wholesale and brokered deposits to supplement our generation of deposits from businesses and consumers. At December 31, 2018, we had $401.6 million in brokered deposits that were raised to supplement and diversify our deposit funding and support our interest rate risk management strategies.The brokered deposits had a weighted average maturity of 5 months and an all-in cost of 233 basis points.

Subsidiaries

The Bank, a California state-chartered commercial bank, is a wholly-owned, consolidated subsidiary of the Corporation. The Corporation also has four unconsolidated Delaware statutory trust subsidiaries, PPBI Statutory Trust I, Heritage Oaks Capital Trust II, Mission Community Capital Trust I and Santa Lucia Bancorp (CA) Capital Trust, and one unconsolidated Connecticut statutory trust subsidiary, First Commerce Bancorp Statutory Trust I. All are used as business trusts in connection with the issuance of trust-preferred securities. These business trusts are described in more detail in “Note 13. Subordinated Debentures” in Item 8 of this Form 10-K.

    Personnel

As of December 31, 2018, we had 1,016 full-time employees and 14 part-time employees. The employees are not represented by a collective bargaining unit and we consider our relationship with our employees to be satisfactory.

    Competition

We consider our Bank to be a community bank focused on the commercial banking business, with our primary market encompassing California. To a lesser extent, we also compete in several broader regional and national markets through our HOA Banking, SBA, Franchise Lending and CRE and multi-family lines of business.

The banking business is highly competitive with respect to virtually all products and services. The industry continues to consolidate, and unregulated competitors in the banking markets have focused products targeted at highly profitable customer segments. Many largely unregulated competitors are able to compete across geographic boundaries and provide customers increasing access to meaningful alternatives to nearly all significant banking services and products.

The banking business is dominated by a relatively small number of major banks with many offices operating over a wide geographical area. These banks have, among other advantages, the ability to finance wide-ranging and effective advertising campaigns, and to allocate their resources to regions of highest yield and demand. Many of the national or super-regional banks operating in our primary market area offer certain services that we do not offer directly but may offer indirectly through correspondent institutions. By virtue of their greater total capitalization, the national or super-regional banks also have significantly higher lending limits than us.

In addition to other local community banks, our competitors include commercial banks, savings banks, credit unions, and numerous non-banking institutions, such as finance companies, leasing companies, insurance companies, brokerage firms and investment banking firms. Increased competition has also developed from specialized finance and non-finance companies that offer wholesale finance, credit card, and other consumer finance services, including on-line banking services and personal financial software. Strong competition for deposit and loan products affects the rates of those products, as well as the terms on which they are offered to customers. Mergers between financial institutions have placed additional pressure on banks within the industry to streamline their operations, reduce expenses, and increase revenues to remain competitive.

Technological innovations have also resulted in increased competition in the financial services market. Such innovation has, for example, made it possible for non-depository institutions to offer customers automated transfer payment services that previously were considered traditional banking products. In addition, many customers now expect a choice of delivery systems and channels, including telephone, mobile phones, mail, home computers, ATMs, self-service branches, and/or in-store branches. The sources of competition in such products include commercial banks, as well as credit unions, brokerage firms, money market and other mutual funds, asset management groups, finance and insurance companies, internet-only financial intermediaries and mortgage banking firms.

We work to anticipate and adapt to competitive conditions, whether developing and marketing innovative products and services, adopting or developing new technologies that differentiate our products and services, or providing highly personalized banking services. We strive to distinguish ourselves from other community banks and financial services providers in our marketplace by providing a high level of service to enhance customer loyalty and to attract and retain business. However,no assurances can be given that our efforts to compete in our market areas will continue to be successful.

Supervision and Regulation

General.  Bank holding companies, such as the Corporation, and banks, such as the Bank, are subject to extensive regulation and supervision by federal and state regulators. Various requirements and restrictions under state and federal law affect our operations, including reserves against deposits, ownership of deposit accounts, loans, investments, mergers and acquisitions, borrowings, dividends, locations of branch offices and capital requirements. The following is a summary of certain statutes and rules applicable to us. This summary is qualified in its entirety by reference to the particular statute and regulatory provision referred to below and is not intended to be an exhaustive description of all applicable statutes and regulations.

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 and their subsidiaries. The Corporation is also a bank holding company within the meaning of the California Financial Code (the “Financial Code”). As such, the Corporation and its subsidiaries are subject to examination by, and may be required to file reports with, the DBO.

Under changes made by the Dodd-Frank Act, a bank holding company must act as a source of financial and managerial strength to each of its subsidiary banks and to commit resources to support each such subsidiary bank. In order to fulfill its obligations as a source of strength, the Federal Reserve may require a bank holding company to make capital injections into a troubled subsidiary bank. In addition, the Federal Reserve may charge the bank holding company with engaging in unsafe and unsound practices if the bank holding company fails to commit resources to a subsidiary bank or if it undertakes actions that the Federal Reserve believes might jeopardize the bank holding company’s ability to commit resources to such subsidiary bank. The Federal Reserve also 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.

The CFPB is granted broad rulemaking, supervisory and enforcement powers under various federal consumer financial protection laws, including the Equal Credit Opportunity Act, Truth in Lending Act, Real Estate Settlement Procedures Act, Fair Credit Reporting Act, Fair Debt Collection Act, the Consumer Financial Privacy provisions of the Gramm-Leach-Bliley Act and certain other statutes. The CFPB has examination and primary enforcement authority with respect to depository institutions with $10 billion or more in assets, such as the Bank, which is our subsidiary depository institution. The CFPB has authority to prevent unfair, deceptive or abusive practices in connection with the offering of consumer financial products. The CFPB has issued regulatory guidance and has proposed, or will be proposing, regulations on issues that directly relate to our business. Although it is difficult to predict the full extent to which the CFPB’s final rules impact the operations and financial condition of the Bank, such rules may have a material impact on the Bank’s compliance costs, compliance risk and fee income. 

As a California state-chartered commercial bank and member of the Federal Reserve System, 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 (“DIF”). Pursuant to the Dodd-Frank Act, federal deposit insurance coverage was permanently increased to $250,000 per depositor for all insured depository institutions. As a result of this deposit insurance function, the FDIC also has certain supervisory authority and powers over the Bank as well as all other FDIC insured institutions. If, as a result of an examination of the Bank, the regulators should determine that the financial condition, capital resources, asset quality, earnings, 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

11

ultimately, request the FDIC terminate the Bank’s deposit insurance. As a California-chartered commercial bank, the Bank is also subject to certain provisions of California law.

Legislative and regulatory initiatives, which necessarily impact the regulation of the financial services industry, are introduced from time-to-time. We cannot predict whether or when potential legislation or new regulations will be enacted, and if enacted, the effect that new legislation or any implemented regulations and supervisory policies would have on our financial condition and results of operations. Moreover, bank regulatory agencies can be more aggressive in responding to concerns and trends identified in examinations, which could result in an increased issuance of enforcement actions to financial institutions requiring action to address credit quality, liquidity and risk management and capital adequacy, as well as other safety and soundness concerns.

Dodd-Frank Act

The Dodd-Frank Act, which was signed into law in July 2010, implemented far-reaching changes across the financial regulatory landscape, including provisions that, among other things, repealed the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts, and increased the authority of the Federal Reserve to examine bank holding companies, such as the Corporation, and their non-bank subsidiaries.

Many aspects of the Dodd-Frank Act continue to be subject to rulemaking and have yet to take full effect, making it difficult to anticipate the overall financial impact on the Company, its customers or the financial industry generally. Provisions in the legislation that affect deposit insurance assessments, payment of interest on demand deposits and interchange fees could increase the costs associated with deposits as well as place limitations on certain revenues those deposits may generate.

In 2017, both the U.S. House of Representatives and the U.S. Senate introduced legislation that would repeal or modify provisions of the Dodd-Frank Act and significantly impact financial services regulation. In May 2018, certain provisions of these bills were signed into law as part of the Economic Growth, Regulatory Relief and Consumer Protection Act (the “Economic Growth Act”) and repealed or modified significant portions of the Dodd-Frank Act. Specifically, the Economic Growth Act delayed implementation of rules related to the Home Mortgage Disclosure Act, reformed and simplified certain Volcker Rule requirements, and raised the threshold for applying enhanced prudential standards to bank holding companies with total consolidated assets equal to or greater than $50 billion to those with total consolidated assets equal to or greater than $250 billion. While recent federal legislation, including the Economic Growth Act, has scaled back portions of the Dodd-Frank Act, uncertainty about the timing and scope of such changes, as well as the cost of complying with a new regulatory regime, remains.

Activities of Bank Holding Companies.  The activities of bank holding companies are generally limited to the business of banking, managing or controlling banks, and other activities that the Federal Reserve has determined to be so closely related to banking or managing or controlling banks as to be a proper incident thereto. Bank holding companies that qualify and register as “financial holding companies” are also able to engage in certain additional financial activities, such as merchant banking, and securities and insurance underwriting, subject to limitations set forth in federal law. We are not at this date a “financial holding company.”

The BHCA requires a bank holding company to obtain prior approval of the Federal Reserve before: (i) taking any action that causes a bank to become a controlled subsidiary of the bank holding company; (ii) acquiring direct or indirect ownership or control of voting shares of any bank or bank holding company, if the acquisition results in the acquiring bank holding company having control of more than 5% of the outstanding shares of any class of voting securities of such bank or bank holding company, unless such bank or bank holding company is majority-owned by the acquiring bank holding company before the acquisition; (iii) acquiring all or substantially all the assets of a bank; or (iv) merging or consolidating with another bank holding company.

12

Permissible Activities of the Bank.  Because California permits commercial banks chartered by the state to engage in any activity permissible for national banks, the Bank can form subsidiaries to engage in activates “closely related to banking” or “nonbanking” activities and expanded financial activities. However, to form a financial subsidiary, the Bank must be well capitalized and would be subject to the same capital deduction, risk management and affiliate transaction rules as applicable to national banks. Generally, a financial subsidiary is permitted to engage in activities that are “financial in nature” or incidental thereto, even though they are not permissible for the national bank to conduct directly within the bank. The definition of “financial in nature” includes, among other items, underwriting, dealing in or making a market in securities, including, for example, distributing shares of mutual funds. The subsidiary may not, however, engage as principal in underwriting insurance (other than credit life insurance), issue annuities or engage in real estate development, investment or merchant banking.

Incentive Compensation.Federal banking agencies have issued guidance on incentive compensation policies intended to ensure that the incentive compensation policies of banking organizations do not undermine the safety and soundness of such organizations by encouraging excessive risk-taking. The guidance, which covers all employees that have the ability to materially affect the risk profile of an organization, is based upon the key principles that a banking organization’s incentive compensation arrangements should (i) provide incentives that do not encourage risk-taking beyond the organization’s ability to effectively identify and manage risks, (ii) be compatible with effective internal controls and risk management and (iii) be supported by strong corporate governance, including active and effective oversight by the organization’s board of directors. In accordance with the Dodd-Frank Act, the federal banking agencies prohibit incentive-based compensation arrangements that encourage inappropriate risk taking by covered financial institutions (generally institutions that have over $1 billion in assets) and are deemed to be excessive, or that may lead to material losses.

The Federal Reserve will review, as part of the regular, risk-focused examination process, the incentive compensation arrangements of banking organizations, such as the Company, that are not “large, complex banking organizations.” These reviews will be tailored to each organization based on the scope and complexity of the organization’s activities and the prevalence of incentive compensation arrangements. The findings of the supervisory initiatives will be included in reports of examination. Deficiencies will be incorporated into the organization’s supervisory ratings, which can affect the organization’s ability to make acquisitions and take other actions. Enforcement actions may be taken against a banking organization if its incentive compensation arrangements, or related risk-management control or governance processes, pose a risk to the organization’s safety and soundness and the organization is not taking prompt and effective measures to correct the deficiencies.

The scope and content of the U.S. banking regulators’ policies on executive compensation may continue to evolve in the near future. It cannot be determined at this time whether compliance with such policies will adversely affect the Company’s ability to hire, retain and motivate its key employees.

Capital Requirements. Bank holding companies and banks are subject to various regulatory capital requirements administered by state and federal agencies. These agencies may establish higher minimum requirements if, for example, a banking organization previously has received special attention or has a high susceptibility to interest rate risk. Risk-based capital requirements determine the adequacy of capital based on the risk inherent in various classes of assets and off-balance sheet items. Under the Dodd-Frank Act, the Federal Reserve must apply consolidated capital requirements to depository institution holding companies that are no less stringent than those currently applied to depository institutions. The Dodd-Frank Act additionally requires capital requirements to be countercyclical so that the required amount of capital increases in times of economic expansion and decreases in times of economic contraction, consistent with safety and soundness.

Under federal regulations, bank holding companies and banks must meet certain risk-based capital requirements. Effective as of January 1, 2015, the Basel III final capital framework, among other things, (i) introduces as a new capital measure “Common Equity Tier 1” (“CET1”), (ii) specifies that Tier 1 capital consists of CET1 and “Additional Tier 1 capital” instruments meeting specified requirements, (iii) defines CET1 narrowly by requiring that most adjustments to regulatory capital measures be made to CET1 and not to the other components of

13

capital and (iv) expands the scope of the adjustments as compared to existing regulations. Beginning January 1, 2016, financial institutions are required to maintain a minimum capital conservation buffer to avoid restrictions on capital distributions such as dividends and equity repurchases and other payments such as discretionary bonuses to executive officers. The minimum capital conservation buffer is phased in over a four year transition period with minimum buffers of 0.625%, 1.25%, 1.875%, and 2.50% during 2016, 2017, 2018 and 2019, respectively.

As fully phased-in on January 1, 2019, Basel III subjects banks to the following risk-based capital requirements:

• a minimum ratio of CET1 to risk-weighted assets of at least 4.5%, plus a 2.5% “capital conservation buffer”;

• a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the capital conservation buffer, or 8.5%;

• a minimum ratio of Total (Tier 1 plus Tier 2) capital to risk-weighted assets of at least 8.0%, plus the capital conservation buffer, or 10.5%; and

• a minimum leverage ratio of 4%, calculated as the ratio of Tier 1 capital to balance sheet exposures plus certain off-balance sheet exposures.

The Basel III final framework provides for a number of deductions from and adjustments to CET1. These include, for example, the requirement that mortgage servicing rights, deferred tax assets dependent upon future taxable income and significant investments in non-consolidated financial entities be deducted from CET1 to the extent that any one such category exceeds 10% of CET1 or all such categories in the aggregate exceed 15% of CET1. Basel III also includes, as part of the definition of CET1 capital, a requirement that banking institutions include the amount of Additional Other Comprehensive Income (“AOCI”), which primarily consists of unrealized gains and losses on available for sale securities, which are not required to be treated as other-than-temporary impairment, net of tax) in calculating regulatory capital. Banking institutions had the option to opt out of including AOCI in CET1 capital if they elected to do so in their first regulatory report following January 1, 2015. As permitted by Basel III, the Company and the Bank have elected to exclude AOCI from CET1.

The Dodd-Frank Act excludes trust preferred securities issued after May 19, 2010, from being included in Tier 1 capital, unless the issuing company is a bank holding company with less than $500 million in total assets. Trust preferred securities issued prior to that date will continue to count as Tier 1 capital for bank holding companies with less than $15 billion in total assets, such as the Corporation. The trust preferred securities issued by our unconsolidated subsidiary capital trusts qualify as Tier 1 capital up to a maximum limit of 25% of total Tier 1 capital. Any additional portion of our trust preferred securities would qualify as “Tier 2 capital.”

In addition, goodwill and most intangible assets are deducted from Tier 1 capital. For purposes of applicable total risk-based capital regulatory guidelines, Tier 2 capital (sometimes referred to as “supplementary capital”) is defined to include, subject to limitations: perpetual preferred stock not included in Tier 1 capital, intermediate-term preferred stock and any related surplus, certain hybrid capital instruments, perpetual debt and mandatory convertible debt securities, allowances for loan and lease losses, and intermediate-term subordinated debt instruments. The maximum amount of qualifying Tier 2 capital is 100% of qualifying Tier 1 capital. For purposes of determining total capital under federal guidelines, total capital equals Tier 1 capital, plus qualifying Tier 2 capital, minus investments in unconsolidated subsidiaries, reciprocal holdings of bank holding company capital securities, and deferred tax assets and other deductions.

We had outstanding subordinated debentures in the aggregate principal amount of $110.3 million. Of this amount, $25.8 million is attributable to subordinated debentures issued to statutory trusts in connection with prior issuances of trust-preferred securities, $25.0 million of which qualifies as Tier 1 capital and $875,000 of which qualifies as Tier 2 capital, and $84.5 million is attributable to outstanding subordinated notes, all of which qualifies as Tier 2 capital.

14

Basel III changed the manner of calculating risk-weighted assets. New methodologies for determining risk-weighted assets in the general capital rules are included, including revisions to recognition of credit risk mitigation, including a greater recognition of financial collateral and a wider range of eligible guarantors. They also include risk weighting of equity exposures and past due loans; and higher (greater than 100%) risk weighting for certain commercial real estate exposures that have higher credit risk profiles, including higher loan to value and equity components. In particular, loans categorized as “high-volatility commercial real estate” loans (“HVCRE loans”) are required to be assigned a 150% risk weighting, and require additional capital support. HVCRE loans are defined to include any credit facility that finances or has financed the acquisition, development or construction of real property, unless it finances: 1-4 family residential properties; certain community development investments; agricultural land used or usable for, and whose value is based on, agricultural use; or commercial real estate projects in which: (i) the loan to value is less than the applicable maximum supervisory loan to value ratio established by the bank regulatory agencies; (ii) the borrower has contributed cash or unencumbered readily marketable assets, or has paid development expenses out of pocket, equal to at least 15% of the appraised “as completed” value; (iii) the borrower contributes its 15% before the bank advances any funds; and (iv) the capital contributed by the borrower, and any funds internally generated by the project, is contractually required to remain in the project until the facility is converted to permanent financing, sold or paid in full.

In addition to the uniform risk-based capital guidelines and regulatory capital ratios that apply across the industry, the regulators have the discretion to set individual minimum capital requirements for specific institutions at rates significantly above the minimum guidelines and ratios. Future changes in regulations or practices could further reduce the amount of capital recognized for purposes of capital adequacy. Such a change could affect our ability to grow and could restrict the amount of profits, if any, available for the payment of dividends.

In addition, the Dodd-Frank Act requires the federal banking agencies to adopt capital requirements that address the risks that the activities of an institution poses to the institution and the public and private stakeholders, including risks arising from certain enumerated activities.

Basel III became applicable to the Corporation and the Bank on January 1, 2015. Overall, the Corporation believes that implementation of the Basel III Rule has not had and will not have a material adverse effect on the Corporation’s or the Bank’s capital ratios, earnings, shareholder’s equity, or its ability to pay dividends, effect stock repurchases or pay discretionary bonuses to executive officers.

In September 2017, the federal bank regulators proposed to revise and simplify the capital treatment for certain deferred tax assets, mortgage servicing assets, investments in non-consolidated financial entities and minority interests for banking organizations, such as the Corporation and the Bank, that are not subject to the advanced approaches requirements. In November 2017, the federal banking regulators revised the Basel III Rules to extend the current transitional treatment of these items for non-advanced approaches banking organizations until the September 2017 proposal is finalized. The September 2017 proposal would also change the capital treatment of certain commercial real estate loans under the standardized approach, which we use to calculate our capital ratios.

In December 2017, the Basel Committee published standards that it described as the finalization of the Basel III post-crisis regulatory reforms (the standards are commonly referred to as “Basel IV”). Among other things, these standards revise the Basel Committee’s standardized approach for credit risk (including by recalibrating risk weights and introducing new capital requirements for certain “unconditionally cancellable commitments,” such as unused credit card lines of credit) and provides a new standardized approach for operational risk capital. Under the Basel framework, these standards will generally be effective on January 1, 2022, with an aggregate output floor phasing in through January 1, 2027. Under the current U.S. capital rules, operational risk capital requirements and a capital floor apply only to advanced approaches institutions, and not to the Corporation or the Bank. The impact of Basel IV on us will depend on the manner in which it is implemented by the federal bank regulators.

In 2018, the federal bank regulatory agencies issued a variety of proposals and made statements

concerning regulatory capital standards. These proposals touched on such areas as commercial real estate exposure, credit loss allowances under generally accepted accounting principles, capital requirements for covered swap

15

entities, among others. Public statements by key agency officials have also suggested a revisiting of capital policy and supervisory approaches on a going-forward basis. We will be assessing the impact on us of these new regulations and supervisory approaches as they are proposed and implemented.

Prompt Corrective Action Regulations. The federal banking regulators are required to take “prompt corrective action” with respect to capital-deficient institutions. Federal banking regulations define, for each capital category, the levels at which institutions are “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” and “critically undercapitalized.” Under regulations effective through December 31, 2018, the Bank was “well capitalized,” which means it had a common equity Tier 1 capital ratio of 6.5% or higher; a Tier I risk-based capital ratio of 8.0% or higher; a total risk-based capital ratio of 10.0% or higher; a leverage ratio of 5.0% or higher; and was not subject to any written agreement, order or directive requiring it to maintain a specific capital level for any capital measure.

As noted above, Basel III integrates the capital requirements into the prompt corrective action category definitions. The following capital requirements have applied to the Corporation since January 1, 2015.

Capital Category	Total Risk-Based Capital Ratio	Tier 1 Risk-Based Capital Ratio	Common Equity Tier 1 (CET1) Capital Ratio	Leverage Ratio	Tangible Equity to Assets	Supplemental Leverage Ratio
Well Capitalized	10% or greater	8% or greater	6.5% or greater	5% or greater	n/a	n/a
Adequately Capitalized	8% or greater	6% or greater	4.5% or greater	4% or greater	n/a	3% or greater
Undercapitalized	Less than 8%	Less than 6%	Less than 4.5%	Less than 4%	n/a	Less than 3%
Significantly Undercapitalized	Less than 6%	Less than 4%	Less than 3%	Less than 3%	n/a	n/a
Critically Undercapitalized	n/a	n/a	n/a	n/a	Less than 2%	n/a

As of December 31, 2018, the Bank was “well capitalized” according to the guidelines as generally discussed above. As of December 31, 2018, the Corporation had a consolidated ratio of 12.39% of total capital to risk-weighted assets, a consolidated ratio of 11.13% of Tier 1 capital to risk-weighted assets and a consolidated ratio of 10.88% of common equity Tier 1 capital, and the Bank had a ratio of 12.28% of total capital to risk-weighted assets, a ratio of 11.87% of common equity Tier 1 capital and a ratio of 11.87% of Tier 1 capital to risk-weighted assets.

An institution may be downgraded to, or deemed to be in, a capital category that is lower than indicated by its capital ratios if it is determined to be in an unsafe or unsound condition or if it receives an unsatisfactory examination rating with respect to certain matters. An institution’s capital category is determined solely for the purpose of applying prompt corrective action regulations, and the capital category may not constitute an accurate representation of the institution’s overall financial condition or prospects for other purposes.

In the event an institution becomes “undercapitalized,” it must submit a capital restoration plan. The capital restoration plan will not be accepted by the regulators unless each company having control of the undercapitalized institution guarantees the subsidiary’s compliance with the capital restoration plan up to a certain specified amount. Any such guarantee from a depository institution’s holding company is entitled to a priority of payment in bankruptcy. The aggregate liability of the holding company of an undercapitalized bank is limited to the lesser of 5% of the institution’s assets at the time it became undercapitalized or the amount necessary to cause the institution to be “adequately capitalized.” The bank regulators have greater power in situations where an institution becomes “significantly” or “critically” undercapitalized or fails to submit a capital restoration plan. In addition to requiring undercapitalized institutions to submit a capital restoration plan, bank regulations contain broad restrictions on certain activities of undercapitalized institutions including asset growth, acquisitions, branch

16

establishment and expansion into new lines of business. With certain exceptions, an insured depository institution is prohibited from making capital distributions, including dividends, and is prohibited from paying management fees to control persons if the institution would be undercapitalized after any such distribution or payment.

As an institution’s capital decreases, the regulators’ enforcement powers become more severe. A significantly undercapitalized institution is subject to mandated capital raising activities, restrictions on interest rates paid and transactions with affiliates, removal of management, and other restrictions. A regulator has limited discretion in dealing with a critically undercapitalized institution and is virtually required to appoint a receiver or conservator.

Banks with risk-based capital and leverage ratios below the required minimums may also be subject to certain administrative actions, including the termination of deposit insurance upon notice and hearing, or a temporary suspension of insurance without a hearing in the event the institution has no tangible capital.

In addition to the federal regulatory capital requirements described above, the DBO has authority to take possession of the business and properties of a bank in the event that the tangible stockholders’ equity of a bank is less than the greater of (i) 4% of the bank’s total assets or (ii) $1.0 million.

Dividends.  It is the Federal Reserve’s policy that bank holding companies, such as the Corporation, should generally pay dividends on common stock only out of income available over the past year, and only if prospective earnings retention is consistent with the organization’s expected future needs and financial condition. It is also the Federal Reserve’s policy that bank holding companies should not maintain dividend levels that undermine their ability to be a source of strength to its banking subsidiaries. Additionally, in consideration of the current financial and economic environment, the Federal Reserve has indicated that bank holding companies should carefully review their dividend policy and has discouraged payment ratios that are at maximum allowable levels unless both asset quality and capital are very strong. Prior to 2019, we never declared or paid dividends on our common stock. On January 28, 2019 the Corporation’s board of directors declared a $0.22 per share dividend, payable on March 1, 2019 to shareholders of record on February 15, 2019. The Corporation anticipates that it will continue to pay quarterly cash dividends in the future, although there can be no assurance that payment of such dividends will continue or that they will not be reduced. The payment and amount of future dividends remain within the discretion of the Corporation’s board of directors and will depend on the Corporation’s operating results and financial condition, regulatory limitations, tax considerations, and other factors. Interest on deposits will be paid prior to payment of dividends on the Corporation’s common stock.

The Bank’s ability to pay dividends to the Corporation is subject to restrictions set forth in the Financial Code. The Financial Code provides that a bank may not make a cash distribution to its stockholders in excess of the lesser of a bank’s (1) retained earnings; or (2) net income for its last three fiscal years, less the amount of any distributions made by the bank or by any majority-owned subsidiary of the bank to the stockholders of the bank during such period. However, a bank may, with the approval of the DBO, make a distribution to its stockholders in an amount not exceeding the greatest of (a) its retained earnings; (b) its net income for its last fiscal year; or (c) its net income for its current fiscal year. In the event that bank regulators determine that the stockholders’ equity of a bank is inadequate or that the making of a distribution by the bank would be unsafe or unsound, the regulators may order the bank to refrain from making a proposed distribution. The payment of dividends could, depending on the financial condition of a bank, be deemed to constitute an unsafe or unsound practice. Under the foregoing provision of the Financial Code, the amount available for distribution from the Bank to the Corporation was approximately $245.7 million at December 31, 2018.

Approval of the Federal Reserve is required for payment of any dividend by a state chartered bank that is a member of the Federal Reserve, such as the Bank, if the total of all dividends declared by the bank in any calendar year would exceed the total of its retained net income for that year combined with its retained net income for the preceding two years. In addition, a state member bank may not pay a dividend in an amount greater than its undivided profits without regulatory and stockholder approval. The Bank is also prohibited under federal law from paying any dividend that would cause it to become undercapitalized.

FDIC Insurance of Certain Accounts and Regulation by the FDIC.  The Bank is an FDIC insured financial institution whereby the FDIC provides deposit insurance for a certain maximum dollar amount per customer. The Bank, as is true for all FDIC insured banks, is subject to deposit insurance assessments as determined by the FDIC.

Under the FDIC’s risk-based deposit premium assessment system, the assessment rates for an insured depository institution are determined by an assessment rate calculator, which is based on a number of elements that measure the risk each institution poses to the Deposit Insurance Fund.  As a result of the Dodd-Frank Act, the calculated assessment rate is applied to average consolidated assets less the average tangible equity of the insured depository institution during the assessment period to determine the dollar amount of the quarterly assessment. Under the current system, premiums are assessed quarterly and could increase if, for example, criticized loans and leases and/or other higher risk assets increase or balance sheet liquidity decreases.  In addition, the FDIC can impose special assessments in certain instances.  Deposit insurance assessments fund the DIF.  In 2010, the FDIC adopted its DIF restoration plan to ensure that the fund reserve ratio reaches 1.35% of total deposits by September 30, 2020, and the FDIC’s final rule with respect to this became effective July 1, 2016. Insured institutions with assets over $10 billion, such as the Bank, are responsible for funding the increase. Based on the current FDIC insurance assessment methodology, our FDIC insurance premium expense was $3.0 million for 2018, $2.2 million for 2017 and $1.5 million in 2016.

Transactions with Related Parties.  Depository institutions are subject to the restrictions contained in the Federal Reserve Act (the “FRA”) with respect to loans to directors, executive officers and principal stockholders. Under the FRA, loans to directors, executive officers and stockholders who own more than 10% of a depository institution and certain affiliated entities of any of the foregoing, may not exceed, together with all other outstanding loans to such person and affiliated entities, the institution’s loans-to-one-borrower limit as discussed in the above section. Federal regulations also prohibit loans above amounts prescribed by the appropriate federal banking agency to directors, executive officers, and stockholders who own more than 10% of an institution, and their respective affiliates, unless such loans are approved in advance by a majority of the board of directors of the institution. Any “interested” director may not participate in the voting. The proscribed loan amount, which includes all other outstanding loans to such person, as to which such prior board of director approval is required, is the greater of $25,000 or 5% of capital and surplus up to $500,000. The Federal Reserve also requires that loans to directors, executive officers and principal stockholders be made on terms substantially the same as offered in comparable transactions to non-executive employees of the bank and must not involve more than the normal risk of repayment. There are additional limits on the amount a bank can loan to an executive officer.

Transactions between a bank and its “affiliates” are quantitatively and qualitatively restricted under Sections 23A and 23B of the FRA. Section 23A restricts the aggregate amount of covered transactions with any individual affiliate to 10% of the capital and surplus of the financial institution. The aggregate amount of covered transactions with all affiliates is limited to 20% of the institution’s capital and surplus. Certain transactions with affiliates are required to be secured by collateral in an amount and of a type described in Section 23A and the purchase of low quality assets from affiliates are generally prohibited. Section 23B generally provides that certain transactions with affiliates, including loans and asset purchases, must be on terms and under circumstances, including credit standards, that are substantially the same or at least as favorable to the institution as those prevailing at the time for comparable transactions with non-affiliated companies. The Federal Reserve has promulgated Regulation W, which codifies prior interpretations under Sections 23A and 23B of the FRA and provides interpretive guidance with respect to affiliate transactions. Affiliates of a bank include, among other entities, a bank’s holding company and companies that are under common control with the bank. The Corporation is considered to be an affiliate of the Bank.

The Dodd-Frank Act generally enhanced the restrictions on transactions with affiliates under Section 23A and 23B of the FRA, including an expansion of the definition of “covered transactions” and an increase in the amount of time for which collateral requirements regarding covered credit transactions must be satisfied. Insider transaction limitations are expanded through the strengthening of loan restrictions to insiders and

18

the expansion of the types of transactions subject to the various limits, including derivatives transactions, repurchase agreements, reverse repurchase agreements and securities lending or borrowing transactions. Restrictions are also placed on certain asset sales to and from an insider to an institution, including requirements that such sales be on market terms and, in certain circumstances, approved by the institution’s board of directors.

Safety and Soundness Standards.  The federal banking agencies have adopted guidelines designed to assist the federal banking agencies in identifying and addressing potential safety and soundness concerns before capital becomes impaired. The guidelines set forth operational and managerial standards relating to: (i) internal controls, information systems and internal audit systems; (ii) loan documentation; (iii) credit underwriting; (iv) asset growth; (v) earnings; and (vi) compensation, fees and benefits.

In addition, the federal banking agencies have also adopted safety and soundness guidelines with respect to asset quality and for evaluating and monitoring earnings to ensure that earnings are sufficient for the maintenance of adequate capital and reserves. These guidelines provide six standards for establishing and maintaining a system to identify problem assets and prevent those assets from deteriorating. Under these standards, an insured depository institution should: (i) conduct periodic asset quality reviews to identify problem assets; (ii) estimate the inherent losses in problem assets and establish reserves that are sufficient to absorb estimated losses; (iii) compare problem asset totals to capital; (iv) take appropriate corrective action to resolve problem assets; (v) consider the size and potential risks of material asset concentrations; and (vi) provide periodic asset quality reports with adequate information for management and the board of directors to assess the level of asset risk.

Loans to One Borrower.  Under California law, our ability to make aggregate secured and unsecured loans-to-one-borrower is limited to 25% and 15%, respectively, of unimpaired capital and surplus. At December 31, 2018, the Bank’s limit on aggregate secured loans-to-one-borrower was $526.0 million and unsecured loans-to-one borrower was $315.0 million. The Bank has established internal loan limits, which are lower than the legal lending limits for a California bank.

Community Reinvestment Act and the Fair Lending Laws.  The Bank is subject to certain fair lending requirements and reporting obligations involving home mortgage lending operations and Community Reinvestment Act (“CRA”) activities. The CRA generally requires the federal banking regulators to evaluate the record of a financial institution in meeting the credit needs of their local communities, including low and moderate income neighborhoods. In addition to substantial penalties and corrective measures that may be required for a violation of certain fair lending laws, the federal banking agencies may take compliance with such laws and CRA into account when regulating and supervising other activities. A bank’s compliance with its CRA obligations is based on a performance-based evaluation system, which bases CRA ratings on an institution’s lending, service and investment performance, resulting in a rating by the appropriate bank regulator of “outstanding,” “satisfactory,” “needs to improve” or “substantial noncompliance.”  Based on its last CRA examination, the Bank received a “satisfactory” rating.

Bank Secrecy Act and Money Laundering Control Act.  In 1970, Congress passed the Currency and Foreign Transactions Reporting Act, otherwise known as the Bank Secrecy Act (the “BSA”), which established requirements for recordkeeping and reporting by banks and other financial institutions. The BSA was designed to help identify the source, volume and movement of currency and other monetary instruments into and out of the U.S. in order to help detect and prevent money laundering connected with drug trafficking, terrorism and other criminal activities. The primary tool used to implement BSA requirements is the filing of Suspicious Activity Reports. Today, the BSA requires that all banking institutions develop and provide for the continued administration of a program reasonably designed to assure and monitor compliance with certain recordkeeping and reporting requirements regarding both domestic and international currency transactions. These programs must, at a minimum, provide for a system of internal controls to assure ongoing compliance, provide for independent testing of such systems and compliance, designate individuals responsible for such compliance and provide appropriate personnel training.

19

USA Patriot Act.  Under the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act, commonly referred to as the USA Patriot Act or the Patriot Act, financial institutions are subject to prohibitions against specified financial transactions and account relationships, as well as enhanced due diligence standards intended to detect, and prevent, the use of the United States financial system for money laundering and terrorist financing activities. The Patriot Act requires financial institutions, including banks, to establish anti-money laundering programs, including employee training and independent audit requirements, meet minimum standards specified by the act, follow minimum standards for customer identification and maintenance of customer identification records, and regularly compare customer lists against lists of suspected terrorists, terrorist organizations and money launderers. The costs or other effects of the compliance burdens imposed by the Patriot Act or future anti-terrorist, homeland security or anti-money laundering legislation or regulation cannot be predicted with certainty.

Consumer Laws and Regulations.  The Bank is also subject to certain consumer laws and regulations that are designed to protect consumers in transactions with banks. These laws include, among others: Truth in Lending Act; Truth in Savings Act; Electronic Funds Transfer Act; Expedited Funds Availability Act; Equal Credit Opportunity Act; Fair and Accurate Credit Transactions Act; Fair Housing Act; Fair Credit Reporting Act; Fair Debt Collection Act; Home Mortgage Disclosure Act; Real Estate Settlement Procedures Act; laws regarding unfair and deceptive acts and practices; and usury laws. These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must deal with customers when taking deposits or making loans to such customers. The Bank must comply with the applicable provisions of these consumer protection laws and regulations as part of their ongoing customer relations. Many states and local jurisdictions have consumer protection laws analogous, and in addition, to those listed above. Failure to comply with these laws and regulations could give rise to regulatory sanctions, customer rescission rights, action by state and local attorneys general, and civil or criminal liability.

Pursuant to the Dodd-Frank Act, the CFPB has broad authority to regulate and supervise the retail consumer financial products and services activities of banks and various non-bank providers. The CFPB has authority to promulgate regulations, issue orders, guidance and policy statements, conduct examinations and bring enforcement actions with regard to consumer financial products and services. With assets exceeding $10.0 billion at December 31, 2018, the Bank is subject to examination for consumer compliance by the CFPB. The creation of the CFPB by the Dodd-Frank Act has led to, and is likely to continue to lead to, enhanced and strengthened enforcement of consumer financial protection laws.

In addition, federal law currently contains extensive customer privacy protection provisions. Under these provisions, a financial institution must provide to its customers, at the inception of the customer relationship and annually thereafter, the institution’s policies and procedures regarding the handling of customers’ nonpublic personal financial information. These provisions also provide that, except for certain limited exceptions, a financial institution may not provide such personal information to unaffiliated third parties unless the institution discloses to the customer that such information may be so provided and the customer is given the opportunity to opt out of such disclosure.

    Federal and State Taxation

The Corporation and the Bank report their income on a consolidated basis using the accrual method of accounting, and are subject to federal income taxation in the same manner as other corporations with some exceptions. The Company has not been audited by the Internal Revenue Service (“IRS”). For its 2018, the Company was subject to a maximum federal income tax rate of 21.00% and California state income tax rate of 10.84%. For its 2017 and 2016 tax years, the Company was subject to a maximum federal income tax rate of 35.00% and California state income tax rate of 10.84%.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law. The Tax Act includes a number of provisions that impact us, including the following:

20

• Tax Rate. The Tax Act replaces the graduated corporate income tax rates applicable under prior law, which imposed a maximum corporate income tax rate of 35%, with a reduced 21% flat corporate income tax rate. Although the reduced corporate income tax rate generally should be favorable to us, resulting in increased earnings and capital, it decreased the value of our existing deferred tax assets. Accounting principles generally accepted in the United States (“U.S. GAAP”) requires that the impact of the provisions of the Tax Act be accounted for in the period of enactment. Accordingly, the total incremental income tax expense recorded by the Corporation related to the Tax Act was $3.4 million.

• FDIC Insurance Premiums. The Tax Act prohibits taxpayers with consolidated assets over $50 billion from deducting any FDIC insurance premiums and prohibits taxpayers with consolidated assets between $10 and $50 billion from deducting the portion of their FDIC premiums equal to the ratio, expressed as a percentage, that (i) the taxpayer’s total consolidated assets over $10 billion, as of the close of the taxable year, bears to (ii) $40 billion. As such, a portion of the Bank’s FDIC insurance premiums were deemed not deductible for the year ended December 31, 2018 as we completed the acquisition of Grandpoint with $3.05 billion in total assets during 2018 and our total consolidated assets reached $11.49 billion at December 31, 2018.

• Employee Compensation. A “publicly held corporation” is not permitted to deduct compensation in excess of $1 million per year paid to certain employees. The Tax Act eliminates certain exceptions to the $1 million limit applicable under prior law related to performance-based compensation (for example, equity grants and cash bonuses paid only on the attainment of performance goals). As a result, our ability to deduct certain compensation paid to our most highly compensated employees is now limited.

• Business Asset Expensing. The Tax Act allows taxpayers to immediately expense the entire cost (instead of only 50%, as under prior law) of certain depreciable tangible property and real property improvements acquired and placed in service after September 27, 2017 and before January 1, 2023 (with an additional year for certain property). This 100% “bonus” depreciation is phased out proportionately for property placed in service on or after January 1, 2023 and before January 1, 2027 (with an additional year for certain property).

• Interest Expense. The Tax Act limits a taxpayer’s annual deduction of business interest expense to the sum of (i) business interest income, and (ii) 30% of “adjusted taxable income,” defined as a business’s taxable income without taking into account business interest income or expense, net operating losses, and, for 2018 through 2021, depreciation, amortization and depletion. Because we generate significant amounts of net interest income, we do not expect to be impacted by this limitation.

ITEM 1A.  RISK FACTORS

Ownership of our common stock involves certain risks. The risks and uncertainties described below are not the only ones we face. You should carefully consider the risks described below, as well as all other information contained in this Annual Report on Form 10-K. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. If any of these risks actually occurs, our business, financial condition or results of operations could be materially, adversely affected.

Risks Related to Our Business

The economic environment could pose significant challenges for the Company and could adversely affect our financial condition and results of operations.

Our financial condition and results of operations are dependent on the U.S. economy, generally, and markets we serve, specifically. We primarily serve markets in California, though certain of our products and services are offered nationwide. Although the U.S. economy continues a gradual expansion following the severe recession that ended in 2009, the duration and magnitude of the continued expansion is uncertain. Financial stress on borrowers as a result of an uncertain future economic environment could have an adverse effect on the Company’s borrowers and their ability to repay their loans, which could adversely affect the Company’s business, financial condition and results of operations. A weakening of these conditions in the markets in which we operate would likely have an adverse effect on us and others in the financial institutions industry. For example, deterioration in economic conditions in our markets could drive losses beyond that which is provided for in our allowance for loan losses (“ALLL”). We may also face the following risks in connection with these events:

• Economic conditions that negatively affect real estate values and the job market may result, in the deterioration of the credit quality of our loan portfolio, and such deterioration in credit quality could have a negative impact on our business.

• A decrease in the demand for loans and other products and services offered by us.

• A decrease in deposit balances, including low-cost and non-interest bearing deposits, due to overall reductions in the accounts of customers.

• A decrease in the value of our loans or other assets secured by commercial or residential real estate.

• A decrease in net interest income derived from our lending and deposit gathering activities.

• Sustained weakness in our markets may affect consumer confidence levels and may cause adverse changes in payment patterns, causing increases in delinquencies and default rates on loans and other credit facilities.

• The processes we use to estimate ALLL and reserves may no longer be reliable because they rely on complex judgments, including forecasts of economic conditions, which may no longer be capable of accurate estimation.

• Our ability to assess the creditworthiness of our customers may be impaired if the models and approaches we use to select, manage, and underwrite customers become less predictive of future charge-offs.

As these conditions or similar ones exist or worsen, we could experience adverse effects on our business, financial condition and results of operations.

22

Our business is subject to various lending and other economic risks that could adversely impact our results of operations and financial condition.

There can be no assurance that the economic conditions that impact the financial services industry, and the capital, credit and real estate markets generally, will not deteriorate in the near or long term, in which case, we could experience losses and write-downs of assets, and could face capital and liquidity constraints or other business challenges. If economic conditions were to deteriorate, particularly within our geographic regions, it could result in the following additional consequences, any of which could have a material adverse effect on our business, results of operations and financial condition:

• Loan delinquencies may increase causing increases in our provision for loan losses and ALLL and decreases to our capital.

• Collateral for loans, especially real estate, may decline in value, in turn reducing a customer’s borrowing power, and reducing the value of assets and collateral associated with our loans held for investment.

• Consumer confidence levels may decline and cause adverse changes in payment patterns, resulting in increased delinquencies and default rates on loans and other credit facilities and decreased demand for our products and services.

• Performance of the underlying loans in mortgage backed securities may deteriorate to potentially cause OTTI markdowns to our investment portfolio.

Adverse economic conditions in California may cause us to suffer higher default rates on our loans and reduce the value of the assets we hold as collateral.

Our business activities and credit exposure are concentrated in California. Difficult economic conditions, including state and local government deficits, in California may cause us to incur losses associated with higher default rates and decreased collateral values in our loan portfolio. In addition, demand for our products and services may decline. Declines in the California real estate market could hurt our business, because the majority of our loans are secured by real estate located within California. As of December 31, 2018, approximately 59% of the aggregate outstanding principal of our loans was secured by real estate were located in California. If real estate values were to decline in California, the collateral for our loans would provide less security. As a result, our ability to recover on defaulted loans by selling the underlying real estate would be diminished, and we would be more likely to suffer losses on defaulted loans.

Changes in U.S trade policies and other factors beyond the Company’s control may adversely impact our business, financial condition and results of operations.

Following the U.S. presidential election in 2016, there have been changes to U.S. trade policies, legislation, treaties and tariffs, including trade policies and tariffs affecting China and retaliatory tariffs by China. Tariffs, retaliatory tariffs or other trade restrictions on products and materials that our customers import or export, including among others, agricultural and technological products, could cause the prices of our customers’ products to increase which could reduce demand for such products, or reduce our customer margins, and adversely impact their revenues, financial results and ability to service debt; this, in turn, could adversely affect our financial condition and results of operations. In addition, to the extent changes in the political environment have a negative impact on us or on the markets in which we operate, our business, results of operations and financial condition could be materially and adversely impacted in the future. A trade war or other governmental action related to tariffs or international trade agreements or policies has the potential to negatively impact our and our customers’ costs, demand for our customers’ products, and the U.S. economy or certain sectors thereof and, thus, adversely impact our business, financial condition and results of operations.

23

We may suffer losses in our loan portfolio in excess of our allowance for loan losses.

Our total nonperforming assets amounted to $5.0 million, or 0.04% of our total assets, at December 31, 2018, an increase from $3.6 million or 0.04% at December 31, 2017. We had $1.0 million of net loan charge-offs for 2018, unchanged from $1.0 million in 2017. Our provision for loan losses was $8.2 million in 2018, a decrease from $8.6 million in 2017. If increases in our nonperforming assets occur in the future, our net loan charge-offs and/or provision for loan losses may also increase which may have an adverse effect upon our future results of operations and capital.

We seek to mitigate the risks inherent in our loan portfolio by adhering to specific underwriting practices. These practices generally include analysis of a borrower’s prior credit history, financial statements, tax returns and cash flow projections, valuation of collateral based on reports of independent appraisers and liquid asset verifications. Although we believe that our underwriting criteria are appropriate for the various kinds of loans we make, we may incur losses on loans that meet our underwriting criteria, and these losses may exceed the amounts set aside as reserves in our ALLL. Our allowance for probable incurred losses is based on analysis of the following:

• Historical experience with our loans;

• Industry historical losses as reported by the FDIC;

• Evaluation of economic conditions;

• Regular reviews of the quality, mix and size of the overall loan portfolio;

• Regular reviews of delinquencies;

• The quality of the collateral underlying our loans; and

• The effect of external factors, such as competition, legal developments and regulatory requirements.

Although we maintain an ALLL at a level that we believe is adequate to absorb probable incurred losses inherent in our loan portfolio, changes in economic, operating and other conditions, including a sharp decline in real estate values and changes in interest rates, which are beyond our control, may cause our actual loan losses to exceed our current allowance estimates. If the actual loan losses exceed the amount reserved, it will adversely affect our financial condition and results of operations.

In addition, the Federal Reserve and the DBO, as part of their supervisory function, periodically review our ALLL. Either agency may require us to increase our provision for loan losses or to recognize further loan losses, based on their judgments, which may be different from those of our management. Any increase in the ALLL required by them could also adversely affect our financial condition and results of operations.

Risks related to specific segments of our loan portfolio may result in losses that could affect our results of operations and financial condition.

  General economic conditions and local economic conditions, changes in governmental rules, regulations and fiscal policies, and increases in interest rates and tax rates affect our entire loan portfolio. In addition, lending risks vary by the type of loan extended.

In our C&I and SBA lending activities, collectability of loans may be adversely affected by risks generally related to small and middle market businesses, such as:

• Changes or weaknesses in specific industry segments, including weakness affecting the business’ customer base;

• Changes in consumer behavior and a business’ personnel;

• Increases in supplier costs and operating costs that cannot be passed along to customers; and

• Changes in competition.

24

In our investor real estate and construction loans, payment performance and the liquidation values of collateral properties may be adversely affected by risks generally incidental to interests in real property (for investor real estate and CRE construction loans) or risks generally related to consumers (for single family residence construction loans), such as:

• Declines in real estate values, rental rates and occupancy rates;

• Increases in other operating expenses (including energy costs);

• Demand for the type of property or high-end home in question; and

• The availability of property financing.

In our HOA and consumer loans, collectability of the loans may be adversely affected by risks generally related to consumers, such as:

• Changes in consumer behavior and changes or weakness in employment and wage income;

• Declines in real estate values or rental rates;

• Increases in association operating expenses; and

• The availability of property financing.

In our agribusiness and farmland loans, collectability of the loans may be adversely affected by risks generally related to agriculture production and farmlands, such as:

• The cyclical nature of the agriculture industry;

• Fluctuating commodity prices;

• Changing climatic conditions, including drought conditions, which adversely impact agricultural customers’ operating costs, crop yields and crop quality and could impact such customers’ ability to repay loans;

• The imposition of tariffs and retaliatory tariffs or other trade restrictions on agricultural products and materials that our clients import or export; and

• Increases in operating expenses and changes in real estate values.

Our level of credit risk could increase due to our focus on commercial lending and the concentration on small and middle market business customers, who can have heightened vulnerability to economic conditions.

As of December 31, 2018, our commercial real estate loans amounted to $3.7 billion, or 42.2% of our total loan portfolio, and our commercial business loans amounted to $4.1 billion, or 46.8% of our total loan portfolio. At such date, our largest outstanding commercial business loan was $53.2 million, our largest multiple borrower relationship was $131 million and our largest outstanding CRE loan was $94.1 million. CRE and commercial business loans generally are considered riskier than single-family residential loans because they have larger balances to a single borrower or group of related borrowers. CRE and commercial business loans involve risks because the borrowers’ ability to repay the loans typically depends primarily on the successful operation of the businesses or the properties securing the loans. Most of the Company’s commercial business loans are made to small business or middle market customers who may have a heightened vulnerability to economic conditions. Moreover, a portion of these borrowers may not have experienced a complete business or economic cycle. Furthermore, the deterioration of our borrowers’ businesses may hinder their ability to repay their loans with us, which could adversely affect our results of operations.

25

Nonperforming assets take significant time to resolve and adversely affect our results of operations and financial condition.

Nonperforming assets adversely affect our net income in various ways. We generally do not record interest income on nonperforming loans or other real estate owned (“OREO”), which adversely affects our income. When we take collateral in foreclosures and similar proceedings, we are required to mark the related asset to the then fair market value of the collateral, which may ultimately result in a loss. An increase in the level of nonperforming assets increases our risk profile and may impact the capital levels our regulators believe are appropriate in light of the ensuing risk profile. While we reduce problem assets through loan sales, workouts, restructurings and otherwise, decreases in the value of the underlying collateral, or in these borrowers’ performance or financial condition, whether or not due to economic and market conditions beyond our control, could adversely affect our business, results of operations and financial condition. In addition, the resolution of nonperforming assets requires significant commitments of time from management and our directors, which can be detrimental to the performance of their other responsibilities. There can be no assurance that we will not experience future increases in nonperforming assets.

Changes in accounting policies, standards, and interpretations could materially affect how the Company  reports its financial condition and results of operations.

From time to time, the FASB and the SEC change the financial accounting and reporting standards that govern the preparation of the Company’s financial statements. These changes can materially impact how the Company records and reports its financial condition and results of operations.

In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, Measurement of Credit Losses on Financial Instruments. The ASU introduces a new revenue model based on current expected credit losses (“CECL”) rather than incurred losses. The CECL model will apply to most debt instruments, including loan receivables and loan commitments.

Under the CECL model, the Company would recognize an impairment allowance equal to its current estimate of expected life of loan losses for financial instruments as of the end of the reporting period. Measuring expected life of loan losses will likely be a significant challenge for all entities, including the Company. Additionally, the allowance for credit loss(“ACL”) measured under a CECL model could differ materially from the allowance for loan losses (“ALLL”) measured under the Company’s incurred loss model. To initially apply the CECL amendments, for most debt instruments, the Company would record a cumulative-effect adjustment to its statement of financial condition as of the beginning of the first reporting period in which the guidance is effective (a modified retrospective approach). The amendments in ASU 2016-13 are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and are required to be adopted through a modified retrospective approach, with a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is effective. The implementation of CECL may require us to increase our loan loss allowance, decreasing our reported income, and may introduce additional volatility into our reported earnings.

On December 21, 2018, federal bank regulatory agencies approved a final rule, effective as of April 1, 2019, modifying their regulatory capital rules and providing an option to phase in over a three-year period the initial regulatory capital effects of the CECL methodology. The Company is currently evaluating the magnitude of the one-time cumulative adjustment to its allowance and of the ongoing impact of the CECL model on its loan loss allowance and results of operations, together with the final rule that becomes effective as of April 1, 2019, to determine if the phase-in option will be elected.

26

Changes in monetary policy may have a material effect on our results of operations.

Changes in monetary policy, including changes in interest rates, could influence not only the interest we receive on loans and securities and the amount of interest we pay on deposits and borrowings, but also our ability to originate loans and deposits. Historically, there has been an inverse correlation between the demand for loans and interest rates. Loan origination volume usually declines during periods of rising or high interest rates and increases during periods of declining or low interest rates. Changes in interest rates also have a significant impact on the carrying value of certain of our assets, including loans, real estate and investment securities, on our balance sheet. We may incur debt in the future and that debt may also be sensitive to interest rates.

Further, federal monetary policy significantly affects credit conditions for us, as well as for our borrowers, particularly as implemented by the Federal Reserve, primarily through open market operations in U.S. government securities, the discount rate for bank borrowings and reserve requirements. A material change in any of these conditions could have a material impact on us or our borrowers, and therefore on our results of operations.

Interest rate changes, increases or decreases, which are out of our control, could harm profitability.

Our profitability depends to a large extent upon net interest income, which is the difference between interest income and dividends we earn on interest-earning assets, such as loans and investments, and interest expense we pay on interest-bearing liabilities, such as deposits and borrowings. Any change in general market interest rates, whether as a result of changes in the monetary policy of the Federal Reserve or otherwise, may have a significant effect on net interest income.

In response to improving economic conditions, the Federal Reserve Board’s Open Market Committee has slowly increased its federal funds rate target from a range of 0.00% - 0.25%, that was in effect for several years, to the current target range of 2.25% - 2.50%, that was in effect at December 31, 2018. Moreover, since December 2015, the Federal Reserve has removed reserves from the banking system, which also puts upward pressure on market rates of interest. In addition, the prohibition restricting depository institutions from paying interest on demand deposits, such as checking accounts, was repealed as part of the Dodd-Frank Act.

Our assets and liabilities may react differently to changes in overall interest rates or conditions. In general, higher interest rates are associated with a lower volume of loan originations while lower interest rates are usually associated with higher loan originations. Further, if interest rates decline, our loans may be refinanced at lower rates or paid off and our investments may be prepaid earlier than expected. If that occurs, we may have to redeploy the loan or investment proceeds into lower yielding assets, which might also decrease our income. Also, as many of our loans currently have interest rate floors, a rise in rates may increase the cost of our deposits while the rates on the loans remain at their floors, which could decrease our net interest income. Accordingly, changes in levels of market interest rates could materially and adversely affect our financial condition, loan origination volumes, net interest margin, results of operations and profitability.

The Company’s sensitivity to changes in interest rates is low in a rising interest rate environment based on the current profile of the Company’s loan portfolio and low-cost and no-cost deposits. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations-Management of Market Risk.” At December 31, 2018, we had $526.1 million in interest-bearing demand deposits. In addition, at December 31, 2018, we had $3.23 billion in money market and savings deposits. If the interest rates on our loans increase comparably faster than the interest rate on our interest- bearing demand deposits and money market and savings deposits, our core deposit balances may decrease as customers use those funds to repay higher cost loans. In addition, if we need to offer additional interest-bearing demand deposit products or higher interest rates on our current interest-bearing demand, money market or savings deposit accounts in order to maintain current customers or attract new customers, our interest expense will increase, perhaps materially. Furthermore, if we fail to offer competitive rates sufficient to retain these accounts, our core deposits may be reduced, which would

27

require us to seek alternative funding sources or risk slowing our future asset growth. In these circumstances, our net interest income may decrease, which may adversely affect our financial condition and results of operations.

As interest rates rise, our existing borrowers who have adjustable rate loans may see their loan payments increase and, as a result, may experience difficulty repaying those loans, which in turn could lead to higher losses for us.  Increasing delinquencies, non-accrual loans and defaults lead to higher loan loss provisions, and potentially greater eventual losses that would lower our current profitability and capital ratios.   

Conditions in the financial markets may limit our access to additional funding to meet our liquidity needs.

Liquidity is essential to our business, as we must maintain sufficient funds to respond to the needs of depositors and borrowers. An inability to raise funds through deposits, repurchase agreements, federal funds purchased, FHLB advances, the sale or pledging as collateral of loans and other assets could have a substantial negative effect on our liquidity. Our access to funding sources in amounts adequate to finance our activities, or on terms attractive to us, could be impaired by factors that affect us specifically or the financial services industry in general. Factors that could negatively affect our access to liquidity sources include a reduction in our credit ratings, if any, an increase in costs of capital in financial capital markets, negative operating results, a decrease in the level of our business activity due to a market downturn, a decrease in depositor or investor confidence or adverse regulatory action against us. Our ability to borrow could also be impaired by factors that are not specific to us, such as severe disruption of the financial markets or negative news and expectations about the prospects for the financial services industry as a whole.

Our ability to obtain funding from the FHLB or through its overnight federal funds lines with other banks could be negatively affected if we experienced a substantial deterioration in the Company’s financial condition or if such funding became restricted due to deterioration in the financial markets. While the Company has a contingency funds management plan to address such a situation if it were to occur (such plan includes deposit promotions, the sale of securities and the curtailment of loan growth, if necessary), a significant decrease in our ability to borrow funds could adversely affect our liquidity.

As a commercial banking institution, we compete with our market peers in, among other things, attracting, maintaining and increasing customer deposits. We are currently part of a highly competitive local deposit market, in which our competitors are offering ever increasing deposit rates in order to attract new deposits. Given our large proportion of non-maturity deposits, we could experience significant and acute deposit outflows if our offered deposit rates do not remain competitive in our primary market. Such outflows could adversely affect our liquidity.

Further, depending on these competitive factors and the interest rate environment, lower cost deposits may need to be replaced with higher cost funding, resulting in a decrease in net interest income and net income. While these events could have a material impact on our results, we expect, in the ordinary course of business, that these deposits will fluctuate and believes the Company is capable of mitigating this risk, as well as the risk of losing one of these depositors, through additional liquidity, and business generation in the future. However, should a significant number of these customers leave the Bank, it could have a material adverse impact on the Bank and the Company.

 The primary source of the Company’s liquidity from which, among other things, dividends may be paid is the receipt of dividends from the Bank.

We recently initiated the paying of a quarterly cash dividend on our common stock. Our ability to pay cash dividends to our shareholders is dependent upon receiving dividends from the Bank. The Bank’s ability to pay dividends to us is subject to restrictions set forth in the Financial Code. The Financial Code provides that a bank may not make a cash distribution to its stockholders in excess of the lesser of (1) a bank’s retained earnings and (2) a bank’s net income for its last three fiscal years, less the amount of any distributions made by the bank or by any majority-owned subsidiary of the bank to the shareholders of the bank during such period. However, a

bank may, with the approval of the DBO, make a distribution to its stockholders in an amount not exceeding the greatest of (a) its retained earnings; (b) its net income for its last fiscal year; or (c) its net income for its current fiscal year. In the event that banking regulators determine that the stockholders’ equity of a bank is inadequate or that the making of a distribution by the bank would be unsafe or unsound, the regulators may order the bank to refrain from making a proposed distribution.

Approval of the Federal Reserve is required for payment of any dividend by a state chartered bank that is a member of the Federal Reserve System, such as the Bank, if the total of all dividends declared by the Bank in any calendar year would exceed the total of its retained net income for that year combined with its retained net income for the preceding two years. In addition, a state member bank may not pay a dividend in an amount greater than its undivided profits without regulatory and stockholder approval. The Bank is also prohibited under federal law from paying any dividend that would cause it to become undercapitalized.

We may reduce or discontinue the payment of dividends on common stock.

Our shareholders are only entitled to receive such dividends as our Board may declare out of funds legally available for such payments. Although we have only recently begun to declare cash dividends on our common stock, we are not required to do so and may reduce or eliminate our common stock dividend in the future. Our ability to pay dividends to our stockholders is subject to the restrictions set forth in Delaware law, by the Federal Reserve, and by certain covenants contained in our subordinated debentures. Notification to the Federal Reserve is also required prior to our declaring and paying a cash dividend to our shareholders during any period in which our quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements. We may not pay a dividend if the Federal Reserve objects or until such time as we receive approval from the Federal Reserve or we no longer need to provide notice under applicable regulations. In addition, we may be restricted by applicable law or regulation or actions taken by our regulators, now or in the future, from paying dividends to our shareholders. We cannot provide assurance that we will continue paying dividends on our common stock at current levels or at all. A reduction or discontinuance of dividends on our common stock could have a material adverse effect on our business, including the market price of our common stock.

The financial condition of other financial institutions could negatively affect us.

Financial services institutions are interrelated as a result of trading, clearing, counterparty, or other relationships. We have exposure to many different industries and counterparties, and we routinely execute transactions with counterparties in the financial services industry, including commercial banks, brokers and dealers, investment banks and other institutional customers. Many of these transactions expose us to credit risk in the event of a default by a counterparty or customer. In addition, our credit risk may be exacerbated when the collateral held by us cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of the credit or derivative exposure due to us. Any such losses could have a material adverse effect on our financial condition and results of operations.

29

We are dependent on our key personnel.

Our future operating results depend in large part on the continued services of our key personnel, including Steven R. Gardner, our Chairman, President and Chief Executive Officer, who developed and implemented our business strategy. The loss of Mr. Gardner could have a negative impact on the success of our business strategy. In addition, we rely upon the services of Edward Wilcox, President and Chief Operating Officer of the Bank, and Ronald Nicolas, Chief Financial Officer of the Corporation and the Bank, and our ability to attract and retain highly skilled personnel. We cannot assure you that we will be able to continue to attract and retain the qualified personnel necessary for the development of our business. The unexpected loss of services of our key personnel could have a material adverse impact on our business because of their skills, knowledge of our market, years of industry experience and the difficulty of promptly finding qualified replacement personnel. In addition, recent regulatory proposals and guidance relating to compensation may negatively impact our ability to retain and attract skilled personnel.

Security breaches and other disruptions, whether in our systems or those of our contracted partners, could compromise our information and expose us to liability, which would cause our business and reputation to suffer.

In the ordinary course of our business, we collect and store sensitive data, including our proprietary business information and personally identifiable information of our customers and employees in our data centers and on our networks. The secure maintenance and transmission of this information is critical to our operations. Although we devote significant resources to maintain and regularly update our systems and processes that are designed to protect the security of our computer systems, software, networks and other technology assets, as well as the confidentiality, integrity and availability of information belonging to us and our customers, there is no assurance that all of our security measures will provide absolute security.

Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. Like many financial institutions, we can be subject to attempts to infiltrate the security of our websites or other systems which can involve sophisticated and targeted attacks intended to obtain unauthorized access to confidential information, destroy data, disrupt service, sabotage systems or cause other damage, including through the introduction of computer viruses or malware, cyberattacks and other means. We can be targeted by individuals and groups using malicious code and viruses, and can be exposed to distributed denial-of-service attacks with the objective of disrupting on-line banking services.

Despite efforts to ensure the security and integrity of our systems, it is possible that we may not be able to anticipate, detect or recognize threats to our systems or to implement effective preventive measures against all security breaches of these types inside or outside our business, especially because the techniques used frequently are not recognized until launched, and because cyberattacks can originate from a wide variety of sources, including individuals or groups who are or may be involved in organized crime, hostile foreign governments or linked to terrorist organizations. These risks may increase in the future as our web-based product offerings grow or we expand internal usage of web-based applications.

In addition, we outsource a significant portion of our data processing to certain third-party providers. If any of these third-party providers encounters difficulties, or if we have difficulty communicating with them, our ability to adequately process and account for transactions could be affected, and our business operations could be adversely affected. Threats to information security also exist in the processing of customer information through various other vendors and their personnel. We do not have direct control over the systems of these vendors and third-party providers and, were they to suffer a breach, our sensitive data, including customer information, could be accessed, publicly disclosed, lost or stolen

A successful penetration or circumvention of the security of our systems or the systems of another market participant, our vendors or third party providers, which we refer to generally as a data breach, could cause serious negative consequences, including significant disruption of our operations, misappropriation of

30

confidential information, or damage to computers or systems, and may result in violations of applicable privacy and other laws, financial loss, loss of confidence, customer dissatisfaction, significant litigation exposure and harm to our reputation, all of which could have a material adverse effect on our business, financial condition, results of operations, and future prospects.

Any such data breach could compromise our networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, including regulatory mandates specific to the financial services industry, and regulatory penalties, disrupt our operations and the services we provide to customers, damage our reputation, and cause a loss of confidence in our products and services, which could adversely affect our business, revenues and competitive position.

We devote significant resources to protecting our and our customers’ information. To the extent that the expenses associated with these and future protective measures increase, our non-interest expenses may increase overall, which could adversely affect our results of operations. In addition, we maintain cyber risk insurance coverage in amounts that we believe are reasonable based upon the scope of our activities. However, this insurance coverage may not be sufficient to cover all of our losses from future data breaches of our systems or the systems of another market participant or our vendors or third party providers. If our cyber risk insurance is insufficient with respect to covering all of the losses resulting from any such future data breach, our financial condition and results of operations could be adversely affected.

Our controls, processes and procedures may fail or be circumvented.

Management regularly reviews and updates our internal controls over financial reporting, disclosure controls, processes and procedures, and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of our controls, processes and procedures or failure to comply with regulations related to controls, processes and procedures could necessitate changes in those controls, processes and procedures, which may increase our compliance costs, divert management attention from our business or subject us to regulatory actions and increased regulatory scrutiny. Any of these could have a material adverse effect on our business, results of operations, reputation and financial condition.

A natural disaster or recurring energy shortage, especially in California, could harm our business.

We are based in Irvine, California and, at December 31, 2018, approximately 59% of the aggregate outstanding principal of our loans was secured by real estate located in California. In addition, the computer systems that operate our Internet websites and some of their back-up systems are located in Irvine and San Diego, California. Historically, California has been vulnerable to natural disasters. Therefore, we are susceptible to the risks of natural disasters, such as earthquakes, wildfires, floods and mudslides. Natural disasters could harm our operations directly through interference with communications, including the interruption or loss of our information technology structure and websites, which could prevent us from gathering deposits, originating loans and processing and controlling our flow of business, as well as through the destruction of facilities and our operational, financial and management information systems. A natural disaster or recurring power outages may also impair the value of our largest class of assets, our loan portfolio, which is comprised substantially of real estate loans. Uninsured or underinsured disasters may reduce borrowers’ ability to repay mortgage loans. Disasters may also reduce the value of the real estate securing our loans, impairing our ability to recover on defaulted loans through foreclosure and making it more likely that we would suffer losses on defaulted loans. California has also experienced energy shortages, which, if they recur, could impair the value of the real estate in those areas affected. Although we have implemented several back-up systems and protections (and maintain business interruption insurance), these measures may not protect us fully from the effects of a natural disaster. The occurrence of natural disasters or energy shortages in California could have a material adverse effect on our business prospects, financial condition and results of operations.

31

Environmental liabilities with respect to properties on which we take title may have a material effect on our results of operations.

Although we perform limited environmental due diligence in conjunction with originating loans secured by properties we believe have environmental risk, we could be subject to environmental liabilities on real estate properties we foreclose upon and take title to in the normal course of our business. In connection with environmental contamination, we may be held liable to governmental entities or to third parties for property damage, personal injury, investigation and clean-up costs incurred by these parties, or we may be required to investigate or clean-up hazardous or toxic substances at a property. The investigation or remediation costs associated with such activities could be substantial. Furthermore, we may be subject to common law claims by third parties based on damages and costs resulting from environmental contamination even if we were the former owner of a contaminated site. The incurrence of a significant environmental liability could adversely affect our business, financial condition and results of operations. These risks are present even though we perform environmental due diligence on our collateral properties. Such diligence may not reflect all current risks or threats, and unforeseen or unpredictable future events may cause a change in the environmental risk profile of a property after a loan has been made.

We may be unable to successfully compete with financial services companies and other companies that offer banking services.

We face direct competition from a significant number of financial institutions, many with a state-wide or regional presence, and in some cases, a national presence, in both originating loans and attracting deposits. Competition in originating loans comes primarily from other banks and finance companies, and more recently, financial technology (or “fintech”) companies, that make loans in our primary market areas. In addition banks with larger capitalizations and non-bank financial institutions that are not governed by bank regulatory restrictions have larger lending limits and are better able to serve the needs of larger customers. Many of these financial institutions are also significantly larger than us, have greater financial resources than we have, have established customer bases and name recognition. We compete for loans principally on the basis of interest rates and loan fees, the types of loans we offer and the quality of service that we provide to our borrowers. We also face substantial competition in attracting deposits from other banking institutions, money market and mutual funds, credit unions and other investment vehicles. Our ability to attract and retain deposits requires that we provide customers with competitive investment opportunities with respect to rate of return, liquidity, risk and other factors. To effectively compete, we may have to pay higher rates of interest to attract deposits, resulting in reduced profitability. In addition, we rely upon local promotional activities, personal relationships established by our officers, directors and employees and specialized services tailored to meet the individual needs of our customers in order to compete. If we are not able to effectively compete in our market area, our profitability may be negatively affected.

Our ability to attract and maintain customer and investor relationships depends largely on our reputation.

Damage to our reputation could undermine the confidence of our current and potential customers and investors in our ability to provide high-quality financial services. Such damage could also impair the confidence of our counterparties and vendors and ultimately affect our ability to effect transactions. Maintenance of our reputation depends not only on our success in maintaining our service-focused culture and controlling and mitigating the various risks described in this report, but also on our success in identifying and appropriately addressing issues that may arise in areas such as potential conflicts of interest, anti-money laundering, customer personal information and privacy issues, customer and other third-party fraud, record-keeping, technology-related issues including but not limited to cyber fraud, regulatory investigations and any litigation that may arise from the failure or perceived failure to comply with legal and regulatory requirements. Maintaining our reputation also depends on our ability to successfully prevent third parties from infringing on our brands and associated trademarks and our other intellectual property. Defense of our reputation, trademarks and other intellectual property, including through litigation, could result in costs that could have a material adverse effect on our business, financial condition, or results of operations.

32

We are subject to extensive regulation, which could adversely affect our business.

Our operations are subject to extensive regulation by federal, state and local governmental authorities and are subject to various laws and judicial and administrative decisions imposing requirements and restrictions on part or all of our operations. Federal and state banking regulators have significant discretion and authority to prevent or remedy unsafe or unsound practices or violations of laws or regulations by financial institutions and bank holding companies in the performance of their supervisory and enforcement duties. The exercise of regulatory authority may have a negative impact on our financial condition and results of operations. Additionally, in order to conduct certain activities, including acquisitions, we are required to obtain regulatory approval. There can be no assurance that any required approvals can be obtained, or obtained without conditions or on a timeframe acceptable to us.

Because our business is highly regulated, the laws, rules and regulations applicable to us are subject to regular modification and change. Regulations affecting banks and other financial institutions, such as the Dodd-Frank Act, are continuously reviewed and change frequently. For instance, the Dodd-Frank Act has changed the bank regulatory framework, created an independent consumer protection bureau that has assumed the consumer protection responsibilities of the various federal banking agencies, and established more stringent capital standards for banks and bank holding companies. The ultimate effect of such changes cannot be predicted. Because our business is highly regulated, compliance with such regulations and laws may increase our costs and limit our ability to pursue business opportunities. There can be no assurance that laws, rules and regulations will not be proposed or adopted in the future, which could (i) make compliance much more difficult or expensive, (ii) restrict our ability to originate, modify, broker or sell loans or accept certain deposits, (iii) restrict our ability to foreclose on property securing loans, (iv) further limit or restrict the amount of commissions, interest or other charges earned on loans originated or sold by us, or (v) otherwise materially and adversely affect our business or prospects for business. These risks could affect our deposit funding and the performance and value of our loan and investment securities portfolios, which could negatively affect our financial performance and financial condition.

While recent federal legislation has scaled back portions of the Dodd-Frank Act and the current administration in the United States may further roll back or modify certain of the regulations adopted since the financial crisis, including those adopted under the Dodd-Frank Act, uncertainty about the timing and scope of any such changes as well as the cost of complying with a new regulatory regime, may negatively impact our business, at least in the short-term, even if the long-term impact of any such changes are positive for our business.

We are subject to heightened regulatory requirements as our total assets exceed $10 billion.

With the acquisition of Grandpoint on July 1, 2018, our total assets exceeded $10 billion during the quarter ended September 30, 2018. The Dodd-Frank Act and its implementing regulations impose various additional requirements on bank holding companies with $10 billion or more in total assets, including a more frequent and enhanced regulatory examination regime. In addition, banks, including ours, with $10 billion or more in total assets are primarily examined by the CFPB with respect to various federal consumer financial protection laws and regulations, with the Federal Reserve maintaining supervision over some consumer related regulations. Previously, the Federal Reserve has been primarily responsible for examining our Bank’s compliance with consumer protection laws. As a relatively new agency with evolving regulations and practices, there is some uncertainty as to how the CFPB examination and regulatory authority might impact our business.

One key Dodd-Frank Act requirement applicable to banks with $10 billion or more in total assets has been compulsory stress testing (Dodd-Frank Act Stress Test or “DFAST”). The Economic Growth, Regulatory Relief, and Consumer Protection Act, signed into law on May 24, 2018, increased the asset threshold at which company-run stress tests are required from $10 billion to $250 billion. The elimination of DFAST has not eliminated the expectation of the regulatory agencies that we will conduct enhanced capital stress testing. However, standards establishing the framework surrounding such expectations have not been announced. The

33

unknown nature and extent of future stress testing requirements creates uncertainty with respect to the impact of those requirements on our business.

Compliance with stress testing requirements may necessitate that we hire additional compliance or other personnel, design and implement additional internal controls, or incur other significant expenses, any of which could have a material adverse effect on our business, financial condition or results of operations

Federal and state regulatory agencies periodically conduct examinations of our business, including compliance with laws and regulations, and our failure to comply with any supervisory actions to which we are or become subject as a result of such examinations may adversely affect us.

Federal and state regulatory agencies, including the Federal Reserve, the DBO and the FDIC, periodically conduct examinations of our business, including compliance with laws and regulations. If, as a result of an examination, a regulatory agency were to determine that the financial condition, capital resources, asset quality, earnings prospects, management, liquidity or other aspects of any of our operations had become unsatisfactory, or that the Company or its management was in violation of any law or regulation, it may take a number of different remedial actions as it deems appropriate. These actions include the power to enjoin “unsafe or unsound” practices, to require affirmative actions 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 our capital, to restrict our growth, to assess civil monetary penalties against our officers or directors, to remove officers and directors and, if it is concluded that such conditions cannot be corrected or there is an imminent risk of loss to depositors, to terminate our deposit insurance. If we become subject to such regulatory actions, our business, results of operations and reputation may be negatively impacted.  

Changes in the value of goodwill and intangible assets could reduce our earnings.

When the Company acquires a business, a substantial portion of the purchase price of the acquisition is allocated to goodwill and other identifiable intangible assets. The amount of the purchase price, which is allocated to goodwill and other intangible assets is determined by the excess of the purchase price over the fair value of the net identifiable assets acquired. As of December 31, 2018, the Company had approximately $909.3 million of goodwill and intangible assets, which includes goodwill of approximately $808.7 million resulting from the acquisitions the Company has consummated since 2011. The Company accounts for goodwill and intangible assets in accordance with U.S. GAAP, which, in general, requires that goodwill not be amortized, but rather that it is tested for impairment at least annually at the reporting unit level. In testing for impairment of goodwill and intangible assets, the Company first performs a qualitative assessment of goodwill and intangible assets which considers the impact that various relevant economic, industry, market and company specific factors may have on the value of the Company. The Company’s qualitative assessment considers known positive and negative as well as any mitigating events and circumstances associated with each relevant factor that may be deemed to have an impact on the value of the Company. Should the Company’s qualitative assessment indicate the value of goodwill and intangible assets could be impaired, a quantitative assessment is then performed to determine if there is impairment. This assessment involves determining the fair value of the reporting unit (which in our case is the Company) and comparing that determination of fair value to the carrying value of the Company in order to quantify the amount of possible impairment. The estimation of fair values involves a high degree of judgment and subjectivity in the assumptions used. Changes in the local and national economy, the federal and state legislative and regulatory environments for financial institutions, the stock market, interest rates and other external factors (such as natural disasters or significant world events) may occur from time to time, often with great unpredictability, and may materially impact the fair value of publicly traded financial institutions and result in an impairment charge at a future date. If we were to conclude that a future write-down of our goodwill or intangible assets is necessary, we would record the appropriate charge, which could have a material adverse effect on our business, results of operations or financial condition.

34

Recent and potential future acquisitions may disrupt our business.

We have consummated ten acquisitions since 2010. Most recently, on July 1, 2018, we completed the acquisition of Grandpoint, the holding company of Grandpoint Bank, a California state-chartered bank with $3.2 billion in total assets. The success of the Grandpoint acquisition or any future acquisition we may consummate 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 Grandpoint or the target institution, as the case may be, in a manner that does not materially disrupt the existing customer relationships of Grandpoint or the target institution, as the case may be, 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 subject acquisition may not be realized fully or at all or may take longer to realize than expected.

It is possible that the ongoing Grandpoint integration process or the integration process associated with any future acquisition 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 acquisitions. Integration efforts could also divert management attention and resources. These integration matters could have an adverse effect on the combined company.

Potential future acquisitions may dilute stockholder value.

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:

• 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.

35

The tax reform legislation enacted in late 2017 could negatively affect our financial condition and results of operations.

In late 2017, the U.S. Congress passed significant legislation reforming the Internal Revenue Code known as the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). In connection with the preparation of our consolidated financial statements for the fiscal year ended December 31, 2018, we completed the process of determining the accounting for the income tax effect of the Tax Act under ASC Topic 740, Income Taxes, as disclosed in the related notes to the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 and subsequent filings made by us with the SEC. Although the Company has generally benefited from the legislation’s reduction in the federal corporate income tax rate, a tax rate reduction has broader implications for the Company’s operations as the new rates could cause positive or negative impacts on loan demand and on the Company’s pricing models, municipal bonds, tax credits and CRA investments and capital market transactions. Additionally, the interest deduction limitation implemented by the new tax law could make some businesses and industries less inclined to borrow, potentially reducing demand for the Company’s commercial loan products.

Technical corrections or other forthcoming guidance could change how we interpret provisions of the Tax Act, which may impact our effective tax rate and could affect our deferred tax assets, tax positions and/or our tax liabilities. The ultimate overall impact of any tax reform on our business, customers and shareholders is uncertain and could be adverse.

Changes in the fair value of our investment securities may reduce our stockholders’ equity and net income.

At December 31, 2018, $1.10 billion of our securities were classified as available-for-sale. At such date, the aggregate net unrealized loss on our available-for-sale securities was $7.9 million. We increase or decrease stockholders’ equity by the amount of change from the unrealized gain or loss (the difference between the estimated fair value and the amortized cost) of our available-for-sale securities portfolio, net of the related tax, under the category of accumulated other comprehensive income/loss. Therefore, a decline in the estimated fair value of this portfolio will result in a decline in reported stockholders’ equity, as well as book value per common share and tangible book value per common share. This decrease will occur even though the securities are not sold. In the case of debt securities, if these securities are never sold and there are no credit impairments, the decrease will be recovered over the life of the securities. In the case of equity securities, which have no stated maturity, the declines in fair value may or may not be recovered over time.

At December 31, 2018, we had stock holdings in the FHLB of San Francisco totaling $19.6 million, $51.5 million in FRB stock, and $37.7 million in other stock, all carried at cost. The stock held by us is carried at cost and is subject to recoverability testing under applicable accounting standards. For the year ended December 31, 2018, we did not recognize an impairment charge related to our stock holdings. There can be no assurance that future negative changes to the financial condition of the issuers may require us to recognize an impairment charge with respect to such stock holdings.

Risks Related to Ownership of Our Common Stock

The price of our common stock, like many of our peers, has fluctuated significantly over the recent past and may fluctuate significantly in the future, which may make it difficult for you to resell your shares of common stock at times or at prices you find attractive.

Stock price volatility may make it difficult for holders of our common stock to resell their common stock when desired and at desirable prices. Our stock price can fluctuate significantly in response to a variety of factors including, among other things:

• Inaccurate management decisions regarding the fair value of assets and liabilities acquired which could materially affect our financial condition;

• Natural disasters, fires, and severe weather;

• Internal controls may fail;

• Reliance on other companies to provide key components of our business processes;

• Meeting capital adequacy standards and the need to raise additional capital in the future if needed, including through future sales of our common stock;

• Actual or anticipated variations in quarterly results of operations;

• Recommendations by securities analysts;

• Failure of securities analysts to cover, or continue to cover, us;

• Operating and stock price performance of other companies that investors deem comparable to us;

• News reports relating to trends, concerns and other issues in the financial services industry, including the failures of other financial institutions in the current economic downturn;

• Perceptions in the marketplace regarding us and/or our competitors;

• Departure of our management team or other key personnel;

• Cyber security breaches of the company or contracted partners;

• New technology used, or services offered, by competitors;

• Significant acquisitions or business combinations, strategic partnerships, joint ventures or capital commitments by or involving us or our competitors;

• Failure to integrate acquisitions or realize anticipated benefits from acquisitions;

• Existing or increased regulatory and compliance requirements, changes or proposed changes in laws or regulations, or differing interpretations thereof affecting our business, or enforcement of these laws and regulations;

• Litigation and governmental investigations;

• Changes in government regulations; and

• Geopolitical conditions such as acts or threats of terrorism or military conflicts.

General market fluctuations, industry factors and general economic and political conditions and events, such as economic slowdowns or recessions, interest rate changes or credit loss trends, could also cause our stock price to decrease regardless of operating results as evidenced by the current volatility and disruption of capital and credit markets.

In January 2019, we announced the initiation of a quarterly cash dividend. We had not previously declared or paid dividends on our common stock. On January 28, 2019, the Corporation’s board of directors declared a $0.22 per share cash dividend, payable on March 1, 2019 to shareholders of record on February 15, 2019. The Corporation anticipates continuing a regular quarterly cash dividend thereafter targeting a 35% initial payout ratio. However, we have no obligation to pay dividends and we may change our dividend policy at any time without notice to our shareholders. Any future determination to pay dividends to holders of our common stock will depend on our results of operations, financial condition, capital requirements, banking regulations, contractual restrictions and any other factors that our board of directors may deem relevant.

40

Our ability to pay dividends on our common stock is dependent on the Bank’s ability to pay dividends to the Corporation. Various statutory provisions restrict the amount of dividends that the Bank can pay without regulatory approval. For information on the statutory and regulatory limitations on the ability of the Corporation to pay dividends to its stockholders and on the Bank to pay dividends to the Corporation, see “Item 1. Business-Supervision and Regulation—Dividends” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity.”

Unregistered Sales of Equity Securities and Use of Proceeds

On October 26, 2018, the Corporation’s board of directors approved its third stock repurchase program. Under the third stock repurchase program, the Corporation is authorized to repurchase up to $100 million of its common stock. The program may be limited or terminated at any time without prior notice. The Company did not repurchase any shares under the recently approved stock repurchase program. The stock repurchase program is intended to replace and supersede the Company’s prior stock repurchase program, which was approved in June 2012 and authorized the repurchase of up to 1,000,000 shares of the Company’s common stock. An aggregate of 237,455 shares were repurchased under that program.

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 fourth quarter of 2018.

ITEM 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management’s discussion and analysis of financial condition and results of operations is intended to provide a better understanding of the significant changes in trends relating to the Company’s financial condition, results of operation, liquidity and capital resources. This section should be read in conjunction with the disclosures regarding “Forward-Looking Statements” set forth in “Item I. Business-Forward Looking Statements”, as well as the discussion set forth in “Item 8. Financial Statements and Supplementary Data,” including the notes to consolidated financial statements.

Acquisition of Grandpoint

Effective July 1, 2018, we completed our acquisition of Grandpoint pursuant to an agreement and plan of reorganization dated as of February 9, 2018 by and between the Corporation and Grandpoint. Prior to the acquisition, Grandpoint was headquartered in Los Angeles, California and operated 14 regional offices in Southern California. As a result of the acquisition, the Bank acquired approximately$3.05 billion in total assets, $2.40 billion in gross loans and $2.51 billion in total deposits as of the date of the acquisition.

In connection with the consummation of the acquisition, the Corporation issued approximately 15,758,089 shares of its common stock valued at $38.15 per share, which was the closing price for the Corporation’s common stock on June 29, 2018, which was the last trading day prior to the consummation of the merger. The value of the total transaction consideration was approximately $601.2 million after approximately $28.1 million in aggregate cash consideration payable to holders of Grandpoint share-based compensation awards by Grandpoint.

Goodwill in the amount of $313.0 million was recognized in the Grandpoint acquisition. Goodwill represents the future economic benefits rising 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.

Grandpoint acquisition was accounted for using the acquisition method of accounting and accordingly, assets acquired, liabilities assumed and consideration exchanged were recorded at estimated fair value on the acquisition date, in accordance with FASB ASC Topic 805, Business Combinations. 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 subject to refinement for up to one year after the closing date of acquisition as additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. Fair value adjustments will be finalized no later than July 2019.

Summary

Our principal business is attracting deposits from small and middle market businesses and consumers and investing those deposits, together with funds generated from operations and borrowings, primarily in commercial business loans and various types of commercial real estate loans. The Company expects to fund substantially all of the loans that it originates or purchases through deposits, FHLB advances and other borrowings and internally generated funds. Deposit flows and cost of funds are influenced by prevailing market rates of interest primarily on competing investments, account maturities and the levels of savings in the Company’s market area. The Company generates the majority of its revenues from interest income on loans that it originates and purchases, income from investment in securities and service charges on customer accounts. The Company’s revenues are partially offset by interest expense paid on deposits and borrowings, the provision for loan losses and noninterest expenses, such as operating expenses. The Company’s operating expenses primarily consist of employee compensation and benefit expenses, premises and occupancy expenses, data processing and communication

43

expenses and other general expenses.The Company’s results of operations are also affected by prevailing economic conditions, competition, government policies and other actions of regulatory agencies.

Critical Accounting Policies and Estimates

We have established various accounting policies that govern the application of accounting principles generally accepted in the United States of America in the preparation of the Company’s financial statements in Item 8 hereof. The Company’s significant accounting policies are described in Note 1 to the Consolidated Financial Statements. Certain accounting policies require management to make estimates and assumptions that 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 consolidated statements of financial condition dates and the Company’s results of operations for future reporting periods.

Allowance for Loan Losses

We consider the determination of ALLL to be among our critical accounting policies,requiring judicious estimates and assumptions in the preparation of the Company’s financial statements and being particularly susceptible to significant change. The Company maintains an ALLL at a level deemed appropriate by management to provide for known or probable incurred losses in the portfolio at the consolidated statements of financial condition date. The Company has implemented and adheres to an internal loan review system and loss allowance methodology designed to provide for the detection of problem loans and maintenance of an adequate allowance to cover loan losses. Management’s determination of the adequacy of ALLL is based on an evaluation of the composition of the portfolio, actual loss experience, industry charge-off experience on loans, current economic conditions, and other relevant factors in the areas in which the Company’s lending and real estate activities are based. These factors may affect the borrowers’ ability to pay and the value of the underlying collateral. The allowance is calculated by applying loss factors to loans held for investment according to loan type and loan credit classification. The loss factors are evaluated on a quarterly basis and established based primarily upon the Bank’s historical loss experience and, to a lesser extent, the industry charge-off experience. Various regulatory agencies, as an integral part of their examination process, periodically review the Company’s ALLL. Such agencies may require the Bank to recognize additions to the allowance based on judgments different from those of management. In the opinion of management, and in accordance with the credit loss allowance methodology, the present allowance is considered adequate to absorb estimable and probable credit losses. Additions and reductions to the allowance are reflected in current operations. Charge-offs to the allowance are made when specific loans (or portions thereof) are considered uncollectible or are transferred to OREO and the fair value of the property is less than the loan’s recorded investment. Recoveries are credited to the allowance.

Although management uses the best information available to make these estimates, future adjustments to the allowance may be necessary due to economic, operating, regulatory and other conditions that may be beyond the Company’s control. For further information on the ALLL, see Notes 1 and 5 to the Consolidated Financial Statements in Item 8 hereof.

Business Combinations 

We account for acquisitions under the acquisition method. All identifiable assets acquired and liabilities assumed are recorded at fair value. Any excess of the purchase price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. Identifiable intangible assets include core deposit intangibles, which have a definite life. Core deposit intangibles (“CDI”) are subsequently amortized over the estimated life up to 10 years and are tested for impairment annually. Goodwill generated from business combinations is deemed to have an indefinite life and is not subject to amortization, and instead is tested for impairment at least annually.

44

As part of the estimation of fair value, we review each loan or loan pool acquired to determine whether there is evidence of deterioration in credit quality since inception and if it is probable that the Company will be unable to collect all amounts due under the contractual loan agreements. We consider expected prepayments and estimated cash flows including principal and interest payments at the date of acquisition. If a loan is determined to be a purchased credit impaired (“PCI”) loan, the amount in excess of the estimated future cash flows is not accreted into earnings (non-accretable difference). The amount in excess of the estimated future cash flows over the book value of the loan is accreted into interest income over the remaining life of the loan (accretable yield). The Company records these loans on the acquisition date at their net realizable value. Thus, an allowance for estimated future losses is not established on the acquisition date. Losses or a reduction in cash flow, which arise subsequent to the date of acquisition are reflected as a charge through the provision for loan losses. An increase in the expected cash flows adjusts the level of the accretable yield recognized on a prospective basis over the remaining life of the loan.

Income Taxes

Deferred tax assets and liabilities are recorded for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns using the asset liability method. In estimating future tax consequences, all expected future events other than enactments of changes in the tax laws or rates are considered. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are to be recognized for temporary differences that will result in deductible amounts in future years and for tax carryforwards if, in the opinion of management, it is more likely than not that the deferred tax assets will be realized. See also Note 14 of the Consolidated Financial Statements in Item 8 hereof.

Fair Value of Financial Instruments

We use fair value measurements to record fair value adjustments to certain financial instruments and to determine fair value disclosures. Investment securities available-for-sale are financial instruments recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record at fair value other financial assets on a non-recurring basis, such as impaired loans and OREO. These non-recurring fair value adjustments typically involve application of lower-of-cost-or-market accounting or write-downs of individual assets. During the first quarter of 2018, the Company adopted ASU 2016-01 and measures the fair value of financial instruments reported at amortized cost on the consolidated statement of financial condition using the exit price notion. Further, we include in Note 18 to the Consolidated Financial Statements information about the extent to which fair value is used to measure assets and liabilities, the valuation methodologies used and its impact to earnings. Additionally, for financial instruments not recorded at fair value we disclose the estimate of their fair value.

Operating Results

Overview.  The comparability of financial information is affected by our acquisitions. On July 1, 2018, the Company completed the acquisition of Grandpoint.

Non-GAAP Measurements

The Company uses certain non-GAAP financial measures to provide meaningful supplemental information regarding the Company’s operational performance and to enhance investors’ overall understanding of such financial performance. However, these non-GAAP financial measures are supplemental and are not a substitute for an analysis based on GAAP measures and may not be comparable to non-GAAP financial measures that may be presented by other companies. The non-GAAP measures used in this Form 10-K include the following:

• Tangible common equity: Total stockholders’ equity is reduced by the amount of intangible assets, including goodwill.

45

• Tangible common equity amounts and ratios, tangible assets and tangible book value per share: Given that the use of these measures is prevalent among banking regulators, investors and analysts, we disclose them in addition to equity-to-assets ratio, total assets and book value per share, respectively.

The following tables provide reconciliations of the non-GAAP measures with financial measures defined by GAAP:

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 and mix of interest-earning assets and interest-bearing liabilities.

For 2018, net interest income totaled $392.7 million, an increase of $145.2 million or 59% from 2017. The increase reflected an increase in average interest-earning assets of $3.25 billion, primarily due to the acquisition of Grandpoint on July 1, 2018 and PLZZ on November 1, 2017, which at acquisition added $2.40 billion and $1.06 billion of loans, respectively, and organic loan growth from new loan originations of $1.62 billion in 2018, partially offset by an increase in interest-bearing liabilities of $1.81 billion and loan paydowns of $1.28 billion. Net interest margin increased 1 basis point to 4.44% from 2017, primarily due to the yield on interest-earning assets’ increasing 23 basis points and a higher level of increases in the balances of interest-earning assets relative to interest-bearing liabilities, offset by a 41 basis point increase in the cost of interest-bearing liabilities.

For 2017, net interest income totaled $247.5 million, an increase of $94.4 million or 62% from 2016. The increase reflected an increase in average interest-earning assets of $2.17 billion, primarily due to the acquisitions of HEOP and PLZZ in the second and fourth quarter of 2017, respectively. Net interest margin decreased 5 basis points to 4.43% from 2016, primarily due to yield on interest-earning assets decreasing 4 basis points and a slight increase in cost of funds.

46

The following table presents 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.

The table also sets forth our net interest income, net interest rate spread and net interest rate margin for the periods indicated. The net interest rate spread represents the difference between the yield on interest-earning assets and the cost of interest-bearing liabilities. The net interest rate margin reflects the ratio of net interest income as a percentage of interest-earning assets for the year.

Changes in our net interest income are a function of changes in both volumes and mix as well as rates of interest-earning assets and interest-bearing liabilities. The following table presents the impact the volume and rate changes have had on our net interest income for the years 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 the prior period rate);

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

• The change or the combined impact of volume and rate changes allocated proportionately to changes in volume and changes in interest rates.

Provision for Credit Losses.  For 2018, we recorded an $8.3 million provision for credit losses compared to $8.4 million recorded in 2017. The provision included a $96,000 provision primarily for unfunded commitments compared to a provision reversal of $207,000 in 2017. Net loan charge-offs for 2018 amounted to $1.0 million, virtually unchanged from $1.0 million in 2017.

For 2017, we recorded an $8.4 million provision for credit losses compared to $9.3 million recorded in 2016. The $864,000 decrease in the provision for loan losses was primarily attributable to a lower level of net charge-offs for the year, partially offset by the growth in our loan portfolio. Net loan charge-offs for 2017 amounted to $1.0 million, which decreased from $4.8 million in 2016.

Noninterest Income.  For 2018, noninterest income totaled $31.0 million, a decrease of $87,000 or 0.3% from 2017. The decrease was primarily due to a decrease in other income of $2.0 million, which is primarily attributable to lower recoveries of $3.1 million from pre-acquisition charge-offs, and a decrease in other service fee income of $945,000. Also, the Bank had a $1.7 million decrease on the gain on sale of loans, from $12.5 million in 2017 to $10.8 million in 2018. During 2018, we sold $307.5 million of loans with an average price of 103.5%, compared to 2017 in which we sold $223.6 million of loans with an average price of 105.6%. Lastly, gain on sale of investments decreased $1.3 million as the Bank sold $393.1 million of securities during 2018 compared to $260.8 million in 2017. These decreases were offset by an increases of $2.3 million, $1.9 million and $658,000 in debit card interchange fee income, service charges on deposit accounts and loan servicing fees income, respectively, reflecting growth in core transaction deposit and loan accounts from both organic growth and the Grandpoint acquisition. In addition, earnings on banked-owned-life-insurance (“BOLI”) increased $1.1 million, which was primarily the result of a death benefit of $471,000 in 2018 as compared to $63,000 in 2017 and, to a lesser extent, additional BOLI acquired with the Grandpoint and PLZZ acquisitions.

48

For 2017, noninterest income totaled $31.1 million, an increase of $11.5 million or 58.7% from 2016. The increase was primarily due to an increase in other income of $3.0 million, which is primarily attributable to higher recoveries of $2.0 million from pre-acquisition charge-offs, higher service charges on deposit accounts of $1.8 million, growth in core transaction deposit and loan accounts from both organic growth and the acquisitions of HEOP and PLZZ , higher debit card interchange fee income of $1.8 million and higher BOLI income of $926,000. Also, the Bank had a $2.9 million increase on the gain on sale of loans, from $9.5 million in 2016 to $12.5 million in 2017. During 2017, we sold $223.6 million of loans, compared to 2016 in which we sold $112.5 million of loans. Lastly, gain on sale of investments increased $940,000 as the Bank sold $260.8 million of securities during 2017 compared to $221.6 million in 2016.

Noninterest Expense.  For 2018, noninterest expense totaled $249.9 million, an increase of $81.9 million or 48.8% from 2017. The increase in noninterest expense was primarily due to higher compensation and benefits of $45.7 million, which was primarily related to an increase in staff from our acquisition of Grandpoint on July 1, 2018 and PlZZ on November 1, 2017, and internal growth in staff to support our overall growth. Occupancy expense grew by $9.8 million in 2018, mostly due to the HEOP and PLZZ acquisitions in 2017 and Grandpoint acquisition in2018, and the additional branches retained from those acquisitions. The remaining expense categories, excluding merger-related expense, grew by $28.9 million or 60.2% in 2018, due to both a combination of expense growth related to the acquisition of Grandpoint and PLZZ and increased expenses to support the Company’s organic growth in loans and deposits. The most significant increases in expense from these remaining categories were a $7.5 million increase in CDI expenses, $5.2 million increase in data processing costs, $3.9 million increase in legal, audit, and professional expenses, and a $3.7 million increase in deposit related expenses, which include expenses such as lock box services. Merger-related expense decreased $2.5 million as compared to 2017, reflecting the costs of the acquisitions of HEOP and PLZZ in 2017 as compared to the costs of the Grandpoint acquisition in 2018.

For 2017, noninterest expense totaled $168.0 million, an increase of $69.9 million or 71.3% from 2016. The increase in noninterest expense was primarily due to higher compensation and benefits of $31.3 million, primarily related to an increase in staff from our acquisitions of HEOP in April 2017, PLZZ in November 2017, and internal growth in staff to support our overall growth. Merger-related expense increased $16.6 million in 2017 as compared to 2016 reflecting costs from both the HEOP and PLZZ acquisitions in 2017 compared to the SCAF acquisition in 2016. Occupancy expense grew by $4.9 million in 2017, mostly due to the acquisitions and the additional branches retained following the HEOP and PLZZ acquisitions. The remaining expense categories grew by $17.1 million or 55.1% in 2017, due to both a combination of expense growth related to the acquisitions of HEOP and PLZZ and increased expenses to support the Company’s organic growth in loans and deposits. The most significant increases in expense from these remaining categories were a $4.1 million increase in CDI expenses, $3.9 million increase in data processing costs, $3.1 million increase in legal, audit, and professional expenses, and a $1.3 million increase in deposit related expenses, which include expenses such as lock box services.

Income Taxes. The Company recorded income taxes of $42.2 million in 2018, compared with $42.1 million in 2017, and $25.2 million in 2016. Our effective tax rate was 25.5% for 2018, 41.2% for 2017, and 38.6% for 2016. The effective tax rate in each year is affected by various items, including changes in tax law, tax exempt income from municipal securities, BOLI, tax credits from investments in low income housing tax credits (“LIHTC”) and merger-related expense.

The effective tax rate decreased from 41.2% in 2017 to 25.5% in 2018 primarily due to the reduction of the federal income tax rate from 35% to 21% as a result of the Tax Cuts and Jobs Act (“Tax Act”), as well as the re-measurement of deferred tax amounts that existed December 31, 2018 to reflect the initial estimated impact of the Tax Act on those deferred tax amounts in the year of enactment.

See Note 14 to the Consolidated Financial Statements included in Item 8 hereof for further discussion of income taxes and an explanation of the factors, which impact our effective tax rate.

Financial Condition

At December 31, 2018, total assets of the Company were $11.49 billion, up $3.46 billion or 43% from total assets of $8.02 billion at December 31, 2017. The increase in assets in 2018 was primarily related to the $2.64 billion increase in loans held for investment, which was mainly attributable to organic loan growth and the acquisition of Grandpoint on July 1, 2018. The acquisition of Grandpoint added $2.40 billion of loans in the third quarter of 2018 before fair value adjustments.

Investment Activities

Our investment policy, as established by our board of directors, attempts to provide and maintain liquidity, generate a favorable return on investments without incurring undue interest rate and credit risk and complement our lending activities. Specifically, our investment policy generally limits our investments to U.S. government securities, federal agency-backed securities, government-sponsored guaranteed mortgage-backed securities (“MBS”) and collateralized mortgage obligations (“CMO”), municipal bonds, and corporate bonds,

Our investment securities portfolio amounted to $1.15 billion at December 31, 2018, as compared to $805.5 million at December 31, 2017, representing a 43% increase. The increase in securities in 2018 was primarily due to the acquisition of Grandpoint, which increased securities by $393.1 million as well as purchases of $491.3 million, partially offset by sales of $393.1 million and calls, principal pay downs and amortization/accretion of $140.0 million. In general, the purchase of investment securities primarily related to investing excess liquidity from our banking operations, while the sales were made to help fund loan production, which improved our interest-earning asset mix by deploying investment securities dollars into higher yielding loans.

 As of December 31, 2018, our investment securities portfolio consisted of $589.1 million in government-sponsored enterprise (“GSE”) MBS, $238.6 million in municipal bonds, $130.1 million of agency bonds, $103.5 million in corporate bonds, $24.3 million in GSE collateralized mortgage obligations (“CMO”) and $1.8 million in other securities. The total end of period weighted average interest rate on investments at December 31, 2018 was 2.80%, compared to 2.69% at December 31, 2017, reflecting the increased investment in higher yielding corporate bonds. At December 31, 2018, we had an estimated par value of $20.3 million of the GSE securities that were pledged as collateral for the Company’s $75,000 HOA reverse repurchase agreements. The average balance of repurchase agreement facilities was $15.0 million during the year ended December 31, 2018.

The following table lists the percentage of our portfolio exposure to any one issuer as a percentage of capital. The only issuers with greater than 10% exposure are the FNMA and the FHLMC. At December 31, 2018 and December 31, 2017, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of stockholders’ equity.

All of the municipal bond securities in our portfolio have an underlying rating of investment grade, with the majority insured by the largest bond insurance companies to bring each of these securities to a Moody’s A+ rating or better. The Company has predominantly purchased general obligation bonds that are risk-weighted at 20% for regulatory capital purposes. The Company reduces its exposure to any single adverse event by holding securities from geographically diversified municipalities. We are continually monitoring the quality of our municipal bond portfolio in accordance with current financial conditions. To our knowledge, none of the municipalities in which we hold bonds are exhibiting financial problems that would require us to record an OTTI charge. 

The following is a listing of the breakdown by state for our municipal holdings, with all states with greater than 5% of the portfolio listed. 86.3% of the Texas issues are insured by The Texas Permanent School Fund.

Delinquent Loans.  When a borrower fails to make required payments on a loan and does not cure the delinquency within 30 days, we normally initiate formal collection activities including, for loans secured by real estate, recording a notice of default and, after providing the required notices to the borrower, commencing 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. At December 31, 2018, loans delinquent 60 or more days as a percentage of total loans held for investment was 7 basis points, unchanged from 7 basis points at year-end 2017.

(1) All 90 day or greater delinquencies are on nonaccrual status and are reported as part of nonperforming loans.

Nonperforming Assets

Nonperforming assets consist of loans on which we have ceased accruing interest (nonaccrual loans), troubled debt restructured loans, OREO and other repossessed assets owned. Nonaccrual loans consisted of all loans 90 days or more past due and on loans where, in the opinion of management, there is reasonable doubt as to the collection of principal and interest. A “restructured loan” is one where the terms of the loan were renegotiated to provide a reduction or deferral of interest or principal because of deterioration in the financial position of the borrower. We had no troubled debt restructured loans at December 31, 2018 and one troubled debt restructured loan with a recorded balance of $97,000 at December 31, 2017. At December 31, 2018, we had $5.0 million of nonperforming assets, which consisted of $4.9 million of nonperforming loans, $147,000 of OREO, and $13,000 of other repossessed assets owned. At December 31, 2017, we had $3.6 million of nonperforming assets, which consisted of $3.3 million of nonperforming loans and $326,000 of OREO. The increase in nonperforming loans in 2018 as compared to 2017 was primarily due to an SBA loan of $997,000 from PLZZ acquisition in 2017 that became nonaccrual in 2018. It is our policy to take appropriate, timely and aggressive action when necessary to resolve nonperforming assets. When resolving problem loans, it is our policy to determine collectability under various circumstances, which are intended to result in our maximum financial benefit. We accomplish this by

59

working with the borrower to bring the loan current, selling the loan to a third party, or by foreclosing and selling the asset.

At December 31, 2018, OREO consisted of one land property, compared to one commercial owner occupied property and one land property at December 31, 2017. Properties acquired through or in lieu of foreclosure are recorded at fair value less cost to sell. The Company generally obtains an appraisal and/or a market evaluation on all OREO prior to obtaining possession. After foreclosure, valuations are periodically performed by management as needed due to changing market conditions or factors specifically attributable to the property’s condition. If the carrying value of the property exceeds its fair value, less estimated cost to sell, the asset is written down and a charge to operations is recorded.

Allowance for Loan Losses.  The ALLL is established as management’s estimate of probable incurred losses inherent in the loan receivable portfolio. Management evaluates the adequacy of the allowance quarterly to maintain the allowance at levels sufficient to provide for these inherent losses. The ALLL is based upon the total loans evaluated individually and collectively, and is reported as a reduction of loans held for investment. The allowance is increased by a provision for credit losses, which is charged to expense and reduced by charge-offs, net of recoveries.  

We separate our assets, largely loans, by type, and we use various loan classifications to segregate the loans into various risk grade categories. We use the various loan classifications as a means of measuring risk for determining the valuation allowance for groups and individual assets at a point in time. Currently, we designate our

60

assets into a category of “Pass,” “Special Mention,” “Substandard,” “Doubtful” or “Loss.” A brief description of these classifications follows:

• Pass classifications represent loans with a level of credit quality, which contain no well-defined deficiency or weakness.

• Special Mention loans do not currently expose the Bank to a sufficient risk to warrant classification in one of the adverse categories, but possess correctable deficiency or potential weaknesses deserving management’s close attention.

• Substandard loans are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. These loans are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected.  

• Doubtful loans have all the weaknesses inherent in substandard loans, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable.

• 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.

Our determination as to the classification of loans and the amount of valuation allowances necessary are subject to review by bank regulatory agencies, which can order a change in a classification or an increase to the allowance. While we believe that an adequate allowance for estimated loan losses has been established, there can be no assurance that our regulators, in reviewing assets including the loan portfolio, will not request us to materially increase our allowance for estimated loan losses, thereby negatively affecting our financial condition and earnings at that time. In addition, actual losses are dependent upon future events and, as such, further increases to the level of allowances for estimated loan losses may become necessary.

At December 31, 2018, we had $61.5 million of loans classified as substandard, compared to $48.3 million at December 31, 2017, with the increase primarily attributable to acquired classified loans of $26.7 million. There were no loans classified as doubtful as of year-end 2018 or 2017.

In determining the ALLL, we evaluate loan credit losses on an individual basis in accordance with the FASB Accounting Standards Codification (“ASC”) 310, Accounting by Creditors for Impairment of a Loan, and on a collective basis based on FASB ASC 450, Accounting for Contingencies. For loans evaluated on an individual basis, we analyze the borrower’s creditworthiness, cash flows and financial status, and the condition and estimated value of the collateral. Loans evaluated individually that are deemed to be impaired are separated from our collective credit loss analysis.

Unless an individual borrower relationship warrants a separate analysis, the majority of our loans are evaluated for credit losses on a collective basis through a quantitative analysis to arrive at base loss factors that may be adjusted through a qualitative analysis for internally- and externally-identified risks. The adjusted factor is applied against the loan risk category outstanding to determine the appropriate allowance. Potential qualitative adjustments for the following internal and external risk factors include:

Internal Factors

• Changes in lending policies and procedures, including underwriting standards and collection, charge-offs, and recovery practices;

• Changes in the nature and volume of the loan portfolio , as well as new types of lending;

• Changes in the experience, ability, and depth of lending management and other relevant staff that may have an impact on our loan portfolio;

• Changes in the volume and severity of adversely classified or graded loans;

• Changes in the quality of our loan review system and the management oversight; and

• The existence and effect of any concentrations of credit and changes in the level of such concentrations.

External Factors

• Changes in national, state or local economic business conditions and developments affecting the collectability of the portfolio, including the condition of various market segments (includes trends in real estate values, economic activity and the interest rate environment);

• Changes in the value of the underlying collateral for collateral-dependent loans; and

• The effect of external factors, such as competition, legal developments and regulatory requirements on the level of estimated credit losses in our current loan portfolio.

Loans acquired through bank acquisition are recorded at fair value at acquisition date without a carryover of the related ALLL. Purchased credit impaired loans acquired are loans that have evidence of credit deterioration since origination and as to which it is probable at the date of acquisition that the Company will not collect all of principal and interest payments according to the contractual terms. These loans are accounted for under ASC Subtopic 310-30 Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality.

As of December 31, 2018, the ALLL totaled $36.1 million, an increase of $7.1 million from December 31, 2017. At December 31, 2018, the ALLL as a percent of nonperforming loans was 743%, compared with 881% at December 31, 2017.

At December 31, 2018, the ALLL as a percent of loans held for investment was 0.41%, a decrease from 0.47% at December 31, 2017. The decrease in the 2018 ratio was primarily attributable to the loans acquired from Grandpoint, recorded at fair value with no ALLL carried over. Loans acquired from acquisitions were recorded with an average fair value discount of 0.69% and 0.47% at December 31, 2018 and 2017, respectively. At December 31, 2018, management deems the ALLL to be sufficient to provide for probable incurred losses within the loan portfolio.

Deposits

At December 31, 2018, total deposits were $8.66 billion, an increase of $2.57 billion or 42% from December 31, 2017. The increase in deposits since year-end 2017 included increases in noninterest bearing checking of $1.27 billion, money market and savings of$816.8 million, time deposits of $325.9 million and interest-bearing checking of $160.9 million. The increase in deposits during 2018 was primarily due to the acquisition of Grandpoint on July 1, 2018, which contributed $2.5 billion of deposits at the time of acquisition, before purchasing accounting adjustments, as well as organic deposit growth. The total end of period weighted average interest rate on deposits was 0.63% at December 31, 2018 and 0.33% at December 31, 2017.

Borrowings.  Borrowings represent a secondary source of funds for our lending and investing activities. The Company has a variety of borrowing relationships that it can draw upon to fund its activities. At December 31, 2018, total borrowings amounted to $778.0 million, an increase of $136.6 million or 21% from December 31, 2017. The increase in borrowings at December 31, 2018 from December 31, 2017 was primarily related to increases of $177.5 million in FHLB advances and $4.9 million in trust preferred securities, partially offset by a decrease of $46.1 million in repurchase agreements. At December 31, 2018, total borrowings represented 6.8% of total assets and had an end of period weighted average rate of 2.71%, compared with 8.0% of total assets at a weighted average rate of 2.21% at December 31, 2017.

FHLB Advances.  The FHLB system functions as a source of credit to financial institutions that are members. Advances are secured by certain real estate loans, investment securities, and the capital stock of the FHLB owned by the Company. Subject to the FHLB’s advance policies and requirements, these advances can be requested for any business purpose in which the Company is authorized to engage. In granting advances, the FHLB considers a member’s creditworthiness and other relevant factors. The Company has a line of credit with the FHLB, which provides for advances totaling up to 45% of its assets, equating to a credit line of $5.18 billion as of December 31, 2018. At December 31, 2018, we had borrowing capacity of $2.84 billion with the FHLB. At December 31, 2018, the Company had $161.5 million in term FHLB advances and $506.0 million in overnight

67

FHLB advances, compared to $180.0 million in term FHLB advances, which matured within one year, and $310.0 million in overnight FHLB advances at December 31, 2017. The FHLB advances at December 31, 2018 were collateralized by real estate loans with an aggregate balance of $3.30 billion. With this pledged collateral, the Company has additional available advances of $1.78 billion as of December 31, 2018.

Other Borrowings.The Company maintains lines of credit to purchase federal funds and a reverse repurchase facility together totaling $218.0 million with eight correspondent banks and has access through the Federal Reserve Bank discount window to borrow $3.3 million to be utilized as business needs dictate. Federal funds purchased and reverse repurchase facilities are short-term in nature and utilized to meet short-term funding needs. 

The Company sells certain securities under agreements to repurchase. The agreements are treated as overnight borrowings with the obligations to repurchase securities sold reflected as a liability. The dollar amount of investment securities underlying the agreements remain in the asset accounts. The Company enters into these debt agreements as a service to certain HOA depositors to add protection for deposit amounts above FDIC insurance levels. At December 31, 2018, the Company sold securities under agreement to repurchase in the amount of $75,000 with a weighted average rate of 0.01% and collateralized by investment securities with fair value of approximately $20.9 million. The average balance of repurchase agreement facilities was $15.0 million during the year ended December 31, 2018.

Debentures.  On March 2004, the Corporation issued $10.3 million in Floating Rate Junior Subordinated Deferrable Interest Debentures (the “Debt Securities”) to PPBI Trust I, a statutory trust created under the laws of the State of Delaware. The Debt Securities are subordinated to effectively all borrowings of the Corporation and are due and payable on April 7, 2034. Interest is payable quarterly on the Debt Securities at three-month London Interbank Offered Rate (“LIBOR”) plus 2.75% for an effective rate of 5.19% as of December 31, 2018.

In the third quarter of 2014, the Company completed a private placement of $60.0 million in aggregate principal amount of subordinated notes to certain accredited investors. The subordinated notes bear a fixed interest rate of 5.75% per annum, payable semi-annually, and mature on September 3, 2024. The net proceeds from the sale of the notes were $59.0 million, and the notes qualify as Tier 2 capital for regulatory purposes. The Bank received $50.0 million of contributed capital in 2014. At December 31, 2018, the carrying value of the notes was $59.3 million, net of unamortized debt issuance costs of $688,000.

On April 1, 2017, as part of the HEOP acquisition, the Corporation assumed $5.2 million of floating rate junior subordinated debt securities associated with Heritage Oaks Capital Trust II. Interest is payable quarterly at three-month LIBOR plus 1.72% per annum, for an effective rate of 4.12% per annum as of December 31, 2018. At December 31, 2018, the carrying value of these debentures was $4.0 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 December 31, 2018, the carrying value of Mission Community Capital Trust I and Santa Lucia Bancorp (CA) Capital Trust were $2.8 million and $3.8 million, respectively, which reflects purchase accounting fair value adjustments of $306,000 and $1.4 million, respectively. Interest is payable quarterly at three-month LIBOR plus 2.95% per annum, for an effective rate of 5.39% per annum as of December 31, 2018 for Mission Community Capital Trust I. Interest is payable quarterly at three-month LIBOR plus 1.48% per annum, for an effective rate of 3.92% per annum as of December 31, 2018 for Santa Lucia Bancorp (CA) Capital Trust. These three debentures are callable by the Corporation at par.

On November 1, 2017, as part of the PLZZ acquisition, the Company assumed three subordinated notes totaling $25 million at a fixed interest rate of 7.125% payable in arrears on a quarterly basis. The notes have a maturity date of June 26, 2025 and are also redeemable in whole or in part from time to time beginning on June 26, 2020 at an amount equal to 103.0% of principal plus accrued unpaid interest. The redemption price decreases 50 basis points each subsequent year. At December 31, 2018, the carrying value of these subordinated notes was $25.2 million, which reflects purchase accounting fair value adjustments of $157,000.

68

On July 1, 2018, as part of the Grandpoint acquisition, the Corporation assumed $5.2 million in floating rate junior subordinated debt securities associated with First Commerce Bancorp Statutory Trust I. Interest is payable quarterly at three-month LIBOR plus 2.95% per annum, for an effective rate of 5.74% per annum as of December 31, 2018. At December 31, 2018, the carrying value of these debentures was $4.9 million, which reflects purchase accounting fair value adjustments of $224,000.

Stockholders’ Equity

At December 31, 2018, our stockholders’ equity amounted to $1.97 billion, compared with $1.24 billion at December 31, 2017. The increase of $727.7 million or 59% is primarily due to net income in 2018 of $123.3 million and an increase of $610.3 million additional paid-in capital, primarily as a result of the issuance of common stock as part of the Grandpoint acquisition.

Liquidity

Our primary sources of funds are deposits, principal and interest payments on loans, FHLB advances and other borrowings. While maturities and scheduled amortization of loans are a predictable source of funds, deposit flows and loan prepayments are greatly influenced by general interest rates, economic conditions and competition. We seek to maintain a level of liquid assets to ensure a safe and sound operation. Our liquid assets are comprised of cash and unpledged investments. As part of our daily monitoring, we calculate a liquidity ratio by dividing the sum of cash balances plus unpledged securities by the sum of deposits that mature in one year or less plus transaction accounts and FHLB advances. At December 31, 2018, our liquidity ratio was 12.38%, compared with 11.59% at December 31, 2017.

We believe our level of liquid assets is sufficient to meet current anticipated funding needs. At December 31, 2018, liquid assets of the Company represented approximately 9.8% of total assets, compared to 9.2% at December 31, 2017. At December 31, 2018, the Company had eight unsecured lines of credit with other correspondent banks to purchase federal funds totaling $168.0 million, one reverse repo line with a correspondent bank of $50.0 million and access through the Federal Reserve Bank discount window to borrow $3.3 million, as business needs dictate. We also have a line of credit with the FHLB allowing us to borrow up to 45% of the Bank’s total assets. At December 31, 2018, we had a borrowing capacity of $2.84 billion, based on collateral pledged at the FHLB, with $667.5 million outstanding in FHLB borrowing. The FHLB advance line is collateralized by eligible loans. At December 31, 2018, we had approximately $3.30 billion of collateral pledged to secure FHLB borrowings.

At December 31, 2018, the Company’s loan to deposit and borrowing ratio was 93.7%, compared with 92.5% at December 31, 2017. The increase was primarily associated with our loans increasing at a faster rate relative to our deposits and borrowings during the period. Certificates of deposit, which are scheduled to mature in one year or less from December 31, 2018, totaled $1.11 billion. We expect to retain a substantial portion of the maturing certificates of deposit at maturity.

The Bank has a policy in place that permits the purchase of brokered funds, in an amount not to exceed 15% of total deposits, or 12% of total assets, as a secondary source for funding. At December 31, 2018, the Company had $401.6 million, or 3.5% of total assets, in brokered time deposits. At December 31, 2017, the Company had $370.1 million, or 4.6% of total assets, in brokered time deposits.

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. 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 acquired a line of credit with Wells Fargo Bank in June of 2017, with availability of $15.0 million. The line, which matures in June 2019, was added to provide an additional source of liquidity at the Corporation level and has no outstanding balance at December 31, 2018 and December 31, 2017.  

The Financial Code provides that a bank may not make a cash distribution to its stockholders in excess of the lesser of a (i) bank’s retained earnings; or (ii) bank’s net income for its last three fiscal years, less the amount of any distributions made by the bank or by any majority-owned subsidiary of the bank to the stockholders of the bank during such period. However, a bank may, with the approval of the DBO, make a distribution to its stockholders in an amount not exceeding the greatest of (x) its retained earnings; (y) its net income for its last fiscal year; or (z) its net income for its current fiscal year. In the event that the DBO determines that the stockholders’ equity of a bank is inadequate or that the making of a distribution by the bank would be unsafe or unsound, the DBO may order the bank to refrain from making a proposed distribution. Under these provisions, the amount available for distribution from the Bank to the Corporation was approximately $245.7 million at December 31, 2018.

Prior to 2019, the Corporation never declared or paid dividends on its common stock. On January 28, 2019, the Corporation’s board of directors declared a $0.22 per share dividend, payable on March 1, 2019 to

shareholders of record on February 15, 2019. The Corporation anticipates that it will continue to pay quarterly cash dividends in the future, although there can be no assurance that payment of such dividends will continue or that they will not be reduced. The payment and amount of future dividends remain within the discretion of the Corporation’s board of directors and will depend on the Corporation’s operating results and financial condition, regulatory limitations, tax considerations, and other factors. Interest on deposits will be paid prior to payment of dividends on the Corporation’s common stock.

Capital Resources

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

At December 31, 2018, the Bank’s leverage capital was $1.19 billion and risk-weighted capital was $1.23 billion. At December 31, 2017, the Bank’s leverage capital was $805.1 million and risk-weighted capital was $835.9 million. Pursuant to regulatory guidelines under prompt corrective action rules, a bank must have total risk-weighted capital of 10.00% or greater, Tier 1 risk-weighted capital of 8.00% or greater, common equity tier 1 capital ratio of 6.5% and Tier I capital to adjusted tangible assets of 5.00% or greater to be considered “well capitalized.” At December 31, 2018, the Bank’s total risk-weighted capital ratio was 12.28%, Tier 1 risk-weighted capital ratio was 11.87%, common equity Tier 1 risk-weighted capital ratio was 11.87% and Tier I capital to adjusted tangible assets capital ratio was 11.06%. See Note 2 to the Consolidated Financial Statements included in Item 8 hereof for a discussion of the Bank’s and Corporation’s capital ratios.

Impact of Inflation and Changing Prices

Our consolidated financial statements and related data presented in this Annual Report on Form 10-K have been prepared in accordance with accounting principles generally accepted in the United States which require the measurement of financial position and operating results in terms of historical dollar amounts (except with respect to securities classified as available for sale which are carried at market value) without considering the changes in the relative purchasing power of money over time due to inflation. The impact of inflation is reflected in the increased cost of our operations. Unlike most industrial companies, substantially all of our assets and liabilities are monetary in nature. As a result, interest rates have a greater impact on our performance than do the effects of general levels of inflation. Interest rates do not necessarily move in the same direction or to the same magnitude as the price of goods and services.

Impact of New Accounting Standards

See Note 1 to the Consolidated Financial Statements included in Item 8 hereof for a listing of recently issued accounting pronouncements and the impact of them on the Company.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Asset/Liability Management and Market Risk

Market risk is the risk of loss in value or reduced earnings from adverse changes in market prices and interest rates. The Bank’s market risk arises primarily from interest rate risk in our lending and deposit taking activities. Interest rate risk primarily occurs to the degree that the Bank’s interest-bearing liabilities reprice or mature on a different basis and frequency than its interest-earning assets. The Bank’s earnings depend primarily on net interest income, which is the difference between the interest and dividends earned on interest-earning assets and the interest paid on interest-bearing liabilities. Therefore, the Bank actively monitors and manages its portfolios to limit the adverse effects on net interest income and economic value due to changes in interest rates.

The Asset/Liability Committee is responsible for implementing the Bank’s interest rate risk management policy established by the board of directors that sets forth limits of acceptable changes in net interest income (“NII”) and economic value of equity (“EVE”) due to specified changes in interest rates. The Asset/Liability Committee reviews, among other items, economic conditions, the interest rate outlook, the demand for loans, the availability of deposits and borrowings, and the Bank’s current operating results, liquidity, capital and interest rate exposure. Based on these reviews, the Asset/Liability Committee formulates strategies to implement the objectives set forth in the business plan while complying with the net interest income and economic value limits approved by the Bank’s board of directors.

Interest Rate Risk Management.  The principal objective of the Company’s interest rate risk management function is to maintain an interest rate risk profile close to the desired risk profile in light of the interest rate outlook. The Bank measures the interest rate risk included in the major balance sheet portfolios and compares the current risk profile to the desired risk profile and to policy limits set by the board of directors. Management then implements strategies consistent with the desired risk profile. Currently, the Bank’s primary strategy in managing interest rate risk is to focus originations for investment on adjustable rate loans or loans with relatively short maturities. Interest rates on adjustable rate loans are mainly tied to the Prime rate. Likewise, the Bank seeks to raise non-maturity deposits. Management often implements these strategies through pricing actions. Finally, management structures its security portfolio and borrowings to offset some of the interest rate sensitivity created by the re-pricing characteristics of customer loans and deposits.

Management monitors asset and liability maturities and repricing characteristics on a regular basis and evaluates its interest rate risk as it relates to operational strategies. Management analyzes potential strategies for their impact on the interest rate risk profile. Each quarter the Corporation’s board of directors reviews the Bank’s asset/liability position, including simulations showing the impact on the Bank’s economic value of equity in various interest rate scenarios. Interest rate moves, up or down, may subject the Bank to interest rate spread compression, which adversely impacts its net interest income. This is primarily due to the lag in repricing of the indices, to which adjustable rate loans and mortgage-backed securities are tied, as well as their repricing frequencies. Furthermore, large rate moves show the impact of interest rate caps and floors on adjustable rate transactions. This is partly offset by lags in repricing for deposit products. The extent of the interest rate spread compression depends on the direction and severity of interest rate moves and features in the Bank’s product portfolios.

The Company’s interest rate sensitivity is monitored by management through the use of both a simulation model that quantifies the estimated impact to earnings (“Earnings at Risk”) for a twelve and twenty-four month period, and a model that estimates the change in the Company’s EVE under alternative interest rate scenarios, primarily instantaneous parallel interest rate shifts in 100 basis point increments. The simulation model estimates the impact on NII from changing interest rates on interest earning assets and interest expense paid on interest bearing liabilities. The EVE model computes the net present value of equity by discounting all expected cash flows on assets and liabilities under each rate scenario. For each scenario, the EVE is the present value of all assets less the present value of all liabilities. The EVE ratio is defined as the EVE divided by the market value of assets within the same scenario.

73

The following table shows the projected net interest income and net interest margin of the Company at December 31, 2018, assuming instantaneous parallel interest rate shifts in the first period:

December 31, 2018
(dollars in thousands)
Earnings at Risk						Projected Net Interest Margin
Change in Rates (Basis Points)	$ Amount	$ Change		% Change		Rate %	% Change
+200	473,026	5,415		1.2		4.59	1.2
+100	471,474	3,862		0.8		4.57	0.8
Static	467,612	—		—		4.54	—
-100	462,708	(4,904	)	(1.0	)	4.49	(1.0	)
-200	457,900	(9,712	)	(2.1	)	4.44	(2.1	)

The following table shows the EVE and projected change in the EVE of the Company at December 31, 2018, assuming various non-parallel interest rate shifts over a twelve month period:

December 31, 2018
(dollars in thousands)
Economic Value of Equity						EVE as % of market value of portfolio assets
Change in Rates (Basis Points)	$ Amount	$ Change		% Change		EVE Ratio	% Change
+200	3,097,115	154,889		5.3		27.81	0.2
+100	3,036,447	94,221		3.2		26.75	1.3
Static	2,942,226	—		—		25.44	—
-100	2,835,391	(106,835	)	(3.6	)	24.02	(1.4	)
-200	2,723,701	(218,525	)	(7.4	)	22.50	(2.9	)

Based on the modeling of the impact on earnings and EVE from changes in interest rates, the Company’s sensitivity to changes in interest rates is low for rising rates. Both the Earnings at Risk and the EVE increase as rates rise. It is important to note the above tables are forecasts based on several assumptions and that actual results may vary. The forecasts are based on estimates of historical behavior and assumptions by management that may change over time and may turn out to be different. Factors affecting these estimates and assumptions include, but are not limited to (1) competitor behavior, (2) economic conditions both locally and nationally, (3) actions taken by the Federal Reserve, (4) customer behavior and (5) Management’s responses. Changes that vary significantly from the assumptions and estimates may have significant effects on the Company’s earnings and EVE.

The Company does not have any direct market risk from foreign exchange or commodity exposures.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Shareholders and the Board of Directors of Pacific Premier Bancorp, Inc. and Subsidiaries

Irvine, California

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated statements of financial condition of Pacific Premier Bancorp, Inc. and Subsidiaries (the “Company”) as of December 31, 2018 and 2017, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2018, and the related notes (collectively referred to as the “financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2018, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework: (2013) issued by COSO.

Basis for Opinion

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other

75

procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

PACIFIC PREMIER BANCORP, INC., AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business and Summary of Significant Accounting Policies

Description of Business—Pacific Premier Bancorp, Inc., a Delaware corporation organized in 1997 (the “Corporation”), is a California-based bank holding company that owns 100% of the capital stock of Pacific Premier Bank, a California-chartered commercial bank (the “Bank,” and together with the Corporation and its consolidated subsidiaries, the “Company”), the Corporation’s principal operating subsidiary. The Bank was incorporated and commenced operations in 1983.

The principal business of the Company is attracting deposits from the general public and investing those deposits, together with funds generated from operations and borrowings, primarily in business loans and real estate property loans. At December 31, 2018, the Company had 44 depository branches located in the counties of Orange, Los Angeles, Riverside, San Bernardino, San Diego, San Luis Obispo and Santa Barbara, California, as well as Pima and Maricopa Counties, Arizona, Clark County, Nevada and Clark County, Washington. The Company is subject to competition from other financial institutions. The Company is subject to the regulations of certain governmental agencies and undergoes periodic examinations by those regulatory authorities.

Principles of Consolidation—The consolidated financial statements include the accounts of Corporation and its wholly-owned subsidiary the Bank. The Company accounts for its investments in its wholly-owned special purpose entities, PPBI Statutory Trust I, Heritage Oaks Capital Trust II, Mission Community Capital Trust I Santa Lucia Bancorp (CA) Capital Trust and First Commerce Bancorp Statutory Trust I, under the equity method whereby the subsidiary’s net earnings are recognized in the Company’s Statement of Income and the investment in these entities is included in Other Assets on the Company’s Consolidated Statements of Financial Condition. The Company is organized and operates as a single reporting segment, principally engaged in the commercial banking business. All significant intercompany accounts and transactions have been eliminated in consolidation.

Basis of Financial Statement Presentation—The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (‘‘U.S. GAAP’’). Certain amounts in the financial statements and related footnote disclosures for the prior years have been reclassified to conform to the current presentation with no impact to previously reported net income or stockholders’ equity.

Use of Estimates—The preparation of consolidated financial statements in conformity with U.S. GAAP 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, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates may change as new information is obtained.

The following discussion provides a summary of the Company’s significant accounting policies:

Cash and Cash Equivalents—Cash and cash equivalents include cash on hand, cash balances due from banks and federal funds sold. Interest bearing deposits with financial institutions represent primarily cash held at the Federal Reserve Bank of San Francisco. At December 31, 2018, there were no cash reserves required by the Board of Governors of the Federal Reserve System (“Federal Reserve”) for depository institutions based on the amount of deposits held. The Company maintains amounts due from banks that exceed federally insured limits. The Company has not experienced any losses in such accounts.

Securities—The Company has established written guidelines and objectives for its investing activities. At the time of purchase, management designates the security as either held to maturity, available-for-sale or held for

82

trading based on the Company’s investment objectives, operational needs and intent. The investments are monitored to ensure that those activities are consistent with the established guidelines and objectives.

Securities Held-to-Maturity—Investments in debt securities that management has the positive intent and ability to hold to maturity are reported at cost and adjusted for periodic principal payments and the amortization of premiums and accretion of discounts, which are recognized in interest income using the interest method over the period of time to investment’s maturity.

Securities Available-for-Sale—Investments in debt securities that management has no immediate plan to sell, but which may be sold in the future, are carried at fair value. Premiums and discounts are amortized using the interest method over the remaining period to the call date for premiums or contractual maturity for discounts and, in the case of mortgage-backed securities, the estimated average life, which can fluctuate based on the anticipated prepayments on the underlying collateral of the securities. Unrealized holding gains and losses, net of tax, are recorded in a separate component of stockholders’ equity as accumulated other comprehensive income. Realized gains and losses on the sales of securities are determined on the specific identification method, recorded on a trade date basis based on the amortized cost basis of the specific security and are included in noninterest income as net gain (loss) on investment securities.

Impairment of Investments—Quarterly, the Company evaluates investment securities in an unrealized loss position for OTTI. In determining whether a security’s decline in fair value is other-than-temporary, the Company considers a number of factors including: (i) the length of time and the extent to which the fair value of the investment has been less than its amortized cost; (ii) the financial condition and near-term prospects of the issuer; (iii) the intent and ability of the Company to hold the investment for a period of time sufficient to allow for an anticipated recovery in fair value; (iv) downgrades in credit ratings; and (v) general market conditions which reflect prospects for the economy as a whole, including interest rates and sector credit spreads. If it is determined that an OTTI exists, and either the Company intends to sell the investment or it is likely the Company will be required to sell the investment before its anticipated recovery, the total amount of the OTTI, which is measured as the amount by which the investment’s amortized cost exceeds its fair value, is recognized in current period earnings. If the Company has the intent and ability to hold the investment and it is more likely than not it will be required to sell the investment prior to an anticipated recovery of its amortized cost basis, the Company records in current period earnings the portion of OTTI deemed to be credit related, while the remaining portion of OTTI deemed to be non-credit related is recorded in accumulated other comprehensive income. Credit related losses are determined through a discounted cash flow analysis, which incorporates assumptions concerning the estimated timing and amounts of expected cash flows. Non-credit related OTTI losses result from other factors such as change in interest rates and general market conditions. The presentation of OTTI in the consolidated financial statements is on a gross basis with a reduction in the gross amount for the portion of the loss deemed non-credit related and is recorded in accumulated other comprehensive income.

Federal Home Loan Bank Stock—The Bank is a member of the Federal Home Loan Bank System. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are recorded as a component of interest income.

Federal Reserve Bank Stock—The Bank is a member of the Federal Reserve Bank of San Francisco (the “FRB”). FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are recorded as a component of interest income.

Loans Held for Sale—Loans that the Company has the intent to sell prior to maturity have been designated as held for sale at origination and are recorded at lower of cost or fair value. Gains or losses are recognized upon the sale of the loans on a specific identification basis.

83

Loan Servicing Assets—Servicing assets are related to SBA loans sold and are recognized at the time of sale when servicing is retained with the income statement effect recorded in gains on sales of SBA loans. Servicing assets are initially recorded at fair value based on the present value of the contractually specified servicing fee, net of estimated servicing costs, over the estimated life of the loan, using a discount rate. The Company’s servicing costs approximates the industry average servicing costs of approximately 40 basis points. The servicing assets are subsequently amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. The Company periodically evaluates servicing assets for impairment based upon the fair value of the assets as compared to their carrying amount.

The Company typically sells the guaranteed portion of SBA loans and retains the unguaranteed portion (“retained interest”). A portion of the premium on sale of SBA loans is recognized as gain on sale of loans at the time of the sale by allocating the carrying amount between the asset sold and the retained interest, based on their relative fair values. The remaining portion of the premium is recorded as a discount on the retained interest and is amortized over the remaining life of the loan as an adjustment to yield. The retained interest, net of any discount, are included in loans held for investment—net of allowance for loan losses in the accompanying consolidated statements of financial condition.

Loans Held for Investment—Loans held for investment are loans the Company has the ability and intent to hold until their maturity. The loans are carried at amortized cost, net of discounts and premiums on purchased loans, deferred loan origination fees and costs and ALLL. Net deferred loan origination fees and costs on loans are amortized or accreted using the interest method over the expected life of the loans. Amortization of deferred loan fees and costs are discontinued for loans placed on nonaccrual. Any remaining deferred fees or costs and prepayment fees associated with loans that payoff prior to contractual maturity are included in loan interest income in the period of payoff. Loan commitment fees received to originate or purchase a loan are deferred and, if the commitment is exercised, recognized over the life of the loan using the interest method as an adjustment of yield or, if the commitment expires unexercised, recognized as income upon expiration of the commitment.

Interest on loans is recognized using the interest method and is only accrued if deemed collectible. Loans for which the accrual of interest has been discontinued are designated as nonaccrual loans. The accrual of interest on loans is discontinued when principal or interest is past due 90 days based on contractual terms of the loan or when, in the opinion of management, there is reasonable doubt as to collection of principal and or interest. When loans are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Interest income generally is not recognized on nonaccrual loans unless the likelihood of further loss is remote. Interest payments received on nonaccrual loans are applied as a reduction to the loan principal balance. Interest accruals are resumed on such loans only when they are brought current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to all principal and interest.

A loan is considered to be impaired when it is probable that the Company will be unable to collect all amounts due (principal and interest) according to the contractual terms of the loan agreement. The Company reviews loans for impairment when the loan is classified as substandard or worse, delinquent 90 days, determined by management to be collateral dependent, or when the borrower files bankruptcy or is granted concession which qualifies as a troubled debt restructuring. 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. The Company selects the measurement method on a loan-by-loan basis except those loans deemed collateral dependent. Loans for which impairment has been determined are generally charged-off at such time the loan is classified as a loss.

Allowance for Loan Losses—The Company maintains an ALLL at a level deemed appropriate by management to provide for known or probable incurred losses in the portfolio as of the date of the consolidated statements of financial condition. The Company has an internal loan review system and loss allowance methodology designed to provide for the detection of problem loans and an appropriate level of allowance to cover loan losses. Management’s determination of the adequacy of the ALLL is based on an evaluation of the composition

84

of the portfolio, actual loss experience, industry charge-off experience on income property loans, current economic conditions, and other relevant factors in the area in which the Company’s lending and real estate activities are based. These factors may affect the borrower’s ability to pay as well as the value of the underlying collateral securing loans. The allowance is calculated by applying loss factors to loans held for investment according to loan type and loan credit classification. The loss factors are based primarily upon the Bank’s historical loss experience and industry charge-off experience, and are evaluated on a quarterly basis.

At December 31, 2018, the following portfolio segments have been identified. Segments are groupings of similar loans at a level, for which the Company has adopted systematic methods of documentation for determining its allowance for loan losses:

• Commercial and industrial (including Franchise) - Commercial and industrial (“C&I”) loans are secured by business assets including inventory, receivables and machinery and equipment to businesses located generally in our primary market area. Loan types includes revolving lines or credit, term loans, seasonal loans and loans secured by liquid collateral such as cash deposits or marketable securities. Homeowners’ Association (“HOA”) credit facilities are included in C&I loans. We also issue letters of credit on behalf of our customers. Risk arises primarily due to the difference between expected and actual cash flows of the borrowers. In addition, the recoverability of the Company’s investment in these loans is also dependent on other factors primarily dictated by the type of collateral securing these loans. The fair value of the collateral securing these loans may fluctuate as market conditions change. In the case of loans secured by accounts receivable, the recovery of the Company’s investment is dependent upon the borrower’s ability to collect amounts due from its customers.

• Commercial real estate (including owner-occupied and nonowner occupied) - Commercial real estate (“CRE”) includes various type of loans which the Company holds real property as collateral. CRE lending activity is typically restricted to owner-occupied or nonowner-occupied. The primary risks of real estate loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make the real estate loan unprofitable to the borrower. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy.

• SBA - We are approved to originate loans under the SBA’s Preferred Lenders Program (“PLP”). The PLP lending status affords us a higher level of delegated credit autonomy, translating to a significantly shorter turnaround time from application to funding, which is critical to our marketing efforts. We originate loans nationwide under the SBA’s 7(a), SBAExpress, International Trade and 504(a) loan programs, in conformity with SBA underwriting and documentation standards. SBA loans are similar to commercial business loans, but have additional credit enhancement provided by the U.S. Small Business Administration, for up to 85.00% of the loan amount for loans up to $150,000 and 75.00% of the loan amount for loans of more than $150,000. The Company originates SBA loans with the intent to sell the guaranteed portion into the secondary market on a quarterly basis.

• Agribusiness and farmland - We originate loans to the agricultural community to fund seasonal production and longer term investments in land, buildings, equipment, crops and livestock. Agribusiness loans are for the purpose of financing agricultural production to finance crops and livestock. Farmland loans include all land known to be used or usable for agricultural purposes, such as crop and livestock production and is secured by the land and improvements thereon.

• Multi-family - Loans secured by multi-family and commercial real estate properties generally involve a greater degree of credit risk than one-to-four family loans. Because payments on loans secured by multi-family and commercial real estate properties are often dependent on the successful operation or management of the properties, repayment of these loans may be subject to adverse conditions in the real estate market or the economy.

85

• One-to-four family - Although we do not originate, through our bank acquisitions, we have acquired first lien single family loans, we occasionally purchase such loans to diversify our portfolio. The primary risks of one-to-four family loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make loans unprofitable.

• Construction and land - We originate loans for the construction of one-to-four family and multi-family residences and CRE properties in our market area. We concentrate our efforts on single homes and small infill projects in established neighborhoods where there is not abundant land available for development. Construction loans are considered to have higher risks due to construction completion and timing risk, and the ultimate repayment being sensitive to interest rate changes, government regulation of real property and the availability of long-term financing. Additionally, economic conditions may impact the Company’s ability to recover its investment in construction loans, as adverse economic conditions may negatively impact the real estate market, which could affect the borrower’s ability to complete and sell the project. Additionally, the fair value of the underlying collateral may fluctuate as market conditions change. We occasionally originate land loans located predominantly in California for the purpose of facilitating the ultimate construction of a home or commercial building. The primary risks include the borrower’s inability to pay and the inability of the Company to recover its investment due to a decline in the fair value of the underlying collateral.

• Consumer loans - In addition to consumer loans acquired through our various bank acquisitions, we originate a limited number of consumer loans, generally for banking customers only, which consist primarily of home equity lines of credit, savings account secured loans and auto loans. Repayment of these loans is dependent on the borrower’s ability to pay and the fair value of the underlying collateral.

Various regulatory agencies, as an integral part of their examination process, periodically review the Company’s ALLL and loan review process. Such agencies may require the Company to recognize additions to the allowance based on judgments different from those of management.  

In the opinion of management, and in accordance with the credit loss allowance methodology, the present allowance is considered adequate to absorb probable incurred credit losses as of the date of these consolidated financial statements. Additions and reductions to the allowance are reflected in current operations. Charge-offs recorded against the allowance, for all loan segments, are made when specific loans are considered uncollectible or are transferred to other real estate owned and the fair value of the property is less than the Company’s recorded investment in the loan. Recoveries of amounts previously charged-off are credited to the allowance.

Although management uses the best information available to make these estimates, future adjustments to the allowance may be necessary due to economic, operating, regulatory and other conditions that may extend beyond the Company’s control.

Purchased Credit Impaired Loans. As part of business acquisitions, the Bank acquires certain loans that have shown evidence of credit deterioration since origination, referred to as purchased credit impaired loans. These loans are recorded at the fair value, such that no ALLL for purchase credit impaired (“PCI”) is established upon their acquisition. The Company has elected to account for such loans individually. The Company estimates the amount and timing of expected cash flows for each purchased loan, and the expected cash flows in excess of the fair value is recorded as interest income over the remaining life of the loan and is referred to as the accretable yield. The excess of the loan’s contractual principal and interest over expected cash flows is not recorded and is referred to as the non-accretable difference. Over the life of the loan, expected cash flows continue to be estimated. Subsequent decreases in expected future cash flows beyond the expected cash flows as of the acquisition date are accounted for through a charge to the provision for loan losses. If subsequent reforecasts indicate there has been a probable and significant increase in the level of expected future cash flows, the Company first reduces any previously established

86

ALLL for PCI loans and then accounts for the remainder of the increase through interest income as a yield adjustment.

Other Real Estate Owned. Real estate properties acquired through, or in lieu of, loan foreclosure are recorded at fair value, less cost to sell, with any excess loan balance over the fair value of the property charged against the ALLL. The Company obtains an appraisal and/or market valuation on all other real estate owned at the time of possession. After foreclosure, valuations are periodically performed by management. Any subsequent declines in fair value are recorded as a charge to current period earnings with a corresponding write-down to the asset. All legal fees and direct costs, including foreclosure and other related costs are expensed as incurred.

Premises and Equipment. Premises and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets, which range from forty years for buildings, seven years for furniture, fixtures and equipment, and three years for computer and telecommunication equipment. The cost of leasehold improvements is amortized using the straight-line method over the shorter of the estimated useful life of the asset or the term of the related leases.

The Company periodically evaluates the recoverability of long-lived assets, such as premises and equipment, to ensure the carrying value has not been impaired. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Securities Sold Under Agreements to Repurchase. The Company enters into sales of securities under agreement to repurchase. These agreements are treated as financing arrangements and, accordingly, the obligations to repurchase the securities sold are reflected as liabilities in the Company’s consolidated financial statements. The securities collateralizing these agreements are delivered to several major national brokerage firms who arranged the transactions. The securities are reflected as assets in the Company’s consolidated financial statements. The brokerage firms may loan such securities to other parties in the normal course of their operations and agree to return the identical security to the Company at the maturity of the agreements.

Bank Owned Life Insurance. Bank owned life insurance (“BOLI”) is accounted for using the cash surrender value method and is recorded at its realizable value. Changes in the cash surrender value of BOLI are recorded as a component of noninterest 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 indefinite useful lives 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 typically performs its annual impairment testing in the fourth quarter. 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 recorded in the Company’s consolidated balance sheets.

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 asset is consumed or otherwise used up, or on a straight-line amortization method over their estimated useful lives, which ranges from 6 to 11.5 years.

Loan Commitments and Related Financial Instruments. Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.

87

Subordinated Debentures. Long-term borrowings are carried at cost, adjusted for amortization of premiums and accretion of discounts, which are recognized in interest expense using the interest method. Debt issuance costs are recognized in interest expense using the interest method over the life of the instrument.

Stock-Based Compensation. The Company issues various forms of stock-based compensation awards annually to officers and directors of the Company, including stock options, restricted stock awards and restricted stock units. The related compensation costs are recognized in the income statement based on the grant-date fair value over the period they are expected to vest, net of estimates for forfeitures. Estimates for forfeitures are based on the Company’s historical experience for each award type. A Black-Scholes model is utilized to estimate the fair value of stock options. The Black-Scholes model uses certain assumptions to determine grant-date fair value such as: expected volatility, expected term of the option, expected risk-free rate of interest and expected dividend yield on the Company’s common stock. The market price of the Company’s common stock at the grant-date is used for restricted stock awards in determining the grant-date fair value for those awards.

Restricted stock units are granted to officers of the Company. Restricted stock units are stock-based compensation awards that when ultimately settled, result in the payment of cash or the issuance of shares of the Company’s common stock to the holder of the award. As with other stock-based compensation awards, compensation cost for restricted stock units is recognized over the period in which the awards are expected to vest. Certain of the Company’s restricted stock units contain vesting conditions which are based on pre-determined performance targets. The level at which the associated performance targets are achieved can impact the ultimate settlement of the award with the grantee and thus the level of compensation expense ultimately recognized. Certain of these awards contain a market condition whereby the vesting of the award is based on the Company’s performance, such as total shareholder return, relative to its peers over a specified period of time. The grant date fair value of market based restricted stock units is determined through the use of an independent third party which employs the use of a Monte Carlo simulation. The Monte Carlo simulation estimates grant date fair value using input assumptions similar to those used in the Black-Scholes model, however, it also incorporates into the grant date fair value calculation the probability that the performance targets will be achieved. The grant date fair value of restricted stock units that do not contain a market condition for vesting is based on the price of the Company’s common stock on the grant date.

Income Taxes. Deferred tax assets and liabilities are recorded for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns using the asset liability method. In estimating future tax consequences, all expected future events other than enactments of changes in the tax law or rates are considered. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are to be recognized for temporary differences that will result in deductible amounts in future years and for tax carryforwards if, in the opinion of management, it is more likely than not that the deferred tax assets will be realized. At December 31, 2018, no valuation allowance was deemed necessary against the Company’s deferred tax assets. At December 31, 2017, a valuation allowance of $380,000 was recorded against the capital loss carryover deferred tax asset, as the Company does not believe it will generate sufficient capital gain before the capital loss carryover expires.

A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and / or penalties related to income tax matters in income tax expense.

Earnings per Share. Earnings per share of common stock is calculated on both a basic and diluted basis based on the weighted average number of common and common equivalent shares outstanding, excluding common shares in treasury. Basic earnings per share excludes potential dilution and is computed by dividing income available to stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common

88

stock were exercised or converted into common stock or resulted from the issuance of common stock that then would share in earnings.

Comprehensive Income. Comprehensive income is reported in addition to net income for all periods presented. Comprehensive income is a more inclusive financial reporting methodology that includes disclosure of other comprehensive income (loss) that historically has not been recognized in the calculation of net income. Unrealized gains and losses on the Company’s available-for-sale investment securities are required to be included in other comprehensive income or loss. Total comprehensive income (loss) and the components of accumulated other comprehensive income or loss are presented in the Consolidated Statement of Stockholders’ Equity and Consolidated Statements of Comprehensive Income.

Loss Contingencies. Loss contingencies, including claims and legal action arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the financial statements.

Fair Value of Financial Instruments. Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value is an exit price, representing the amount that would be received to sell an asset or transfer a liability in an orderly transaction between market participants. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Fair value measures are classified according to a three-tier fair value hierarchy, which is based on the observability of inputs used to measure fair value. U.S. GAAP requires the Company to maximize the use of observable inputs when measuring fair value. Changes in assumptions or in market conditions could significantly affect these estimates.

Reclassifications. Some items in prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or stockholders’ equity.

Accounting Standards Adopted in 2018

In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 was signed into law, which among other things reduced the maximum federal corporate tax rate from 35% to 21%. This Update addresses concerns about the guidance in current U.S. GAAP that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date. That guidance is applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income (“AOCI”) were originally recognized in other comprehensive income (rather than in income from continuing operations). As a result of the adjustment of deferred taxes being required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income (referred to as stranded tax effects for purposes of this Update) did not reflect the appropriate tax rate. This Update allows for an election to reclassify between retained earnings and AOCI the impact of the federal income tax rate change. The amendments in this Update are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption of the amendments of this Update is permitted. The Company elected to early adopt in the first quarter of 2018. Accordingly, the Company recorded an increase to AOCI and a decrease to retained earnings of approximately $82,000 for stranded tax effects on available for sale investment securities in the first quarter of 2018.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. Under the current implementation guidance in Topic 805, there are three elements of a business-inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a

89

“set”) that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this Update provide a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this Update (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The amendments provide a framework to assist entities in evaluating whether both an input and a substantive process are present. The framework includes two sets of criteria to consider that depend on whether a set has outputs. Although outputs are not required for a set to be a business, outputs generally are a key element of a business; therefore, the Company has developed more stringent criteria for sets without outputs. Lastly, the amendments in this Update narrow the definition of the term output so that the term is consistent with how outputs are described in Topic 606. Public business entities should apply the amendments in this Update to annual periods beginning after December 15, 2017, including interim periods within those periods. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This Update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In August 2016, the FASB issued ASU 2016-15, Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This Update provides guidance on eight specific cash flow classification issues, which include: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments or debt with coupon interest rates that are insignificant in relation to the effective interest rate; 3) contingent consideration payments made soon after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; 6) distributions received from equity method investments; 7) beneficial interest in securitization transactions; and 8) separately identifiable cash flows and the application of the predominance principle. The amendments in this Update are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period; however, an entity is required to adopt all of the amendments in the same period. The amendments in this Update should be applied using a retrospective transition method to each period presented. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, ASU 2018-04, Investments-Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No.33-9273 (SEC Update), ASU 2018-03, Technical Corrections and Improvements to Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. Changes made to the current measurement model primarily affect the accounting for equity securities with readily determinable fair values, where changes in fair value are included in earnings instead of other comprehensive income. The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged. This Update also changes the presentation and disclosure requirements for financial instruments including a requirement that public business entities use exit price when measuring the fair value of financial instruments measured at amortized cost for disclosure purposes. This Update is effective for public business entities in fiscal years beginning after December

90

15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-01 did not have a material effect on the Company’s operating results or financial condition. In accordance with the guidance, the Company measures the fair value of financial instruments reported at amortized cost on the statement of financial condition using the exit price notion. For further details, refer to footnote Fair Value of Financial Instruments within these consolidated financial statements.

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. With this ASU, 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.

The Company adopted the provisions of ASU 2014-09 and its related amendments effective January 1, 2018 utilizing the modified retrospective transition method and determined the adoption was insignificant to the financial statements. Since the impact upon adoption of ASU 2014-09 and its related amendments was insignificant to the financial statements, a cumulative effect adjustment to retained earnings was not deemed necessary.

The Company’s review of its various revenue streams indicated that approximately 99% of the Company’s revenue is out of the scope of ASU 2014-09 and its related amendments, including all of the Company’s net interest income and a significant portion of non-interest income. For those revenue streams that are within the scope of ASU 2014-09 and its related amendments, the Company reviewed the associated customer contracts and agreements to determine the appropriate accounting for revenues under those contracts. The Company’s review did not identify any significant changes in the timing of revenue recognition under those contracts within the scope of ASU 2014-09 and its related amendments. Significant revenue streams that are within scope primarily relate to service charges and fees associated customer deposit accounts, as well as fees for various other services the Company provides its customers. As a result of the implementation of ASU 2014-09 and its related amendments, the Company conducts a detailed review of its revenue streams at least annually, or more frequently if deemed necessary.

Recent Accounting Guidance Not Yet Effective

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this Update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement.

The following disclosure requirements for public companies were removed from Topic 820:

• The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy.

• The policy for timing of transfers between levels.

• The valuation process for Level 3 fair value measurements.

The following disclosure requirements for public companies were modified in Topic 820:

91

• The amendments clarify that the measurement of uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date.

The following disclosure requirements for public companies were added to Topic 820:

• The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period

• The range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements

The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. In addition, an entity may early adopt any of the removed or modified disclosures immediately and delay adoption of the new disclosures until the effective date. The Company is currently evaluating the effects of ASU 2018-13 on its financial statements and disclosures.

In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchase Callable Debt Securities. This Update amends guidance on the amortization period of premiums on certain purchased callable debt securities. The amendments shorten the amortization period of premiums on purchased callable debt securities to the earliest call date. This Update should be applied on a modified retrospective basis through a cumulative-effect adjustment to beginning retained earnings. The effective date of ASU 2017-08 is for interim and annual reporting periods beginning after December 15, 2018. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This Update replaces the incurred loss impairment model in current U.S. GAAP with a model that reflects current expected credit losses (“CECL”). The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures. The Update requires that all expected credit losses for financial assets held at the reporting date be measured based on historical experience, current conditions and reasonable and supportable forecasts. The Update also requires enhanced disclosure, including qualitative and quantitative disclosures that provide additional information about significant estimates and judgments used in estimating credit losses. For public business entities, the Update is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures. The Company has formed a working group and a committee made up of members of finance, credit and risk management that are in the process of compiling and analyzing key data elements and implementing a software model that will meet the requirements of the new guidance. The Company has contracted with an industry expert to: (1) develop a new expected loss model with supportable assumptions, (2) identify data, reporting, and disclosure gaps, (3) provide quantitative modeling, and (4) assess, develop and document updates to accounting policies, new processes and controls. The magnitude of the adjustment and the overall impact of the new guidance on the consolidated financial statements cannot yet be reasonably estimated.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), ASU 2018-11, Leases (Topic 842): Targeted Improvements, ASU 2018-10, Codification Improvements to Topic 842, Leases. This Update is being issued to increase the transparency and comparability around lease obligations. Previously unrecorded off-balance sheet obligations will now be recorded in the consolidated financial statements, accompanied by enhanced qualitative and quantitative disclosures in the notes to the consolidated financial statements. The Update is generally

92

effective for public business entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.

In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842): Targeted Improvements.  ASU 2018-10 provides improvements related to ASU 2016-02 to increase stakeholders’ awareness of the amendments to Topic 842 and to expedite the improvements.  The amendments affect narrow aspects of the guidance issued in ASU 2016-02.  ASU 2018-11 allows entities adopting ASU 2016-02 to choose an additional transition method, under which an entity initially applies the accounting guidance for leases under Topic 842 at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, ASU 2018-11 allows an entity electing this additional transition method to continue to present comparative period financial statements in accordance with Topic 840 (current U.S. GAAP).   ASU 2018-11 also allows lessors to not separate non-lease components from the associated lease component if certain conditions are met.  The amendments in these updates become effective for annual periods as well as interim periods within those annual periods beginning after December 15, 2018.

The Company has elected to apply the transition provisions of Topic 842 using the modified retrospective transition method, electing to adopt the “package” of practical expedients in its transition to Topic 842, as specified in ASC 842-10-65. The results of this policy election are that the Company will reflect the provisions of Topic 842 in its consolidated financial statements for the first time as of and for the period ended March 31, 2019 (the period of adoption). The Company will measure and record liabilities to make lease payments as well as right of use assets in the period of adoption for leases that existed as of the transition date, and will continue to present all comparative periods under Topic 840. Under this elected transition method, the Company is not required to reassess the following as part of its Transition to Topic 842: (1) whether any expired or existing contracts contain leases, (2) lease classifications for any existing or expired leases, and (3) initial direct costs for any existing leases. Additionally, the Company has elected to apply the use of hindsight in its assessment of the term for its leases upon transition, which allows for consideration of the Company’s option to extend or terminate a lease.

The Company is currently in the process of finalizing its transition accounting under Topic 842 and anticipates in the first quarter of 2019 it will record a liability to make future lease payments of approximately $43 million and right of use assets of approximately $41 million, the difference being the net of accounting adjustments previously recorded under Topic 840 and Topic 805, as required by transition guidance in ASC 842-10-65. The Company does not currently anticipate a cumulative effect adjustment to the opening balance of retained earnings will be required as part of its transition to Topic 842. The Company’s evaluation of lease obligations and service agreements under the new standard includes an assessment of the appropriate classification and related accounting of each lease agreement, a review of applicability of the new standard to existing service agreements and gathering all essential lease data to facilitate the application of the new standard. The Company’s review indicates that all of its leases are classified as operating leases or short-term leases. In accordance with the provisions of Topic 842, liabilities to make future lease payments and right of use assets will only be recorded for leases that are not considered short-term (leases with an original term of greater than 12 months). The Company will record expense for its leases on a straight-line basis in accordance with the requirements under Topic 842 for operating leases. The Company does not currently believe expense recognition for its operating leases (including short-term leases) under Topic 842 will differ significantly from that recorded under current lease accounting guidance. Right of use assets for operating leases will be amortized over the lease term and liabilities to make future lease payments will be accounted for using the interest method, both in accordance with Topic 842.

2. Regulatory Capital Requirements and Other Regulatory Matters

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 Bank was categorized as “well capitalized.” There are no conditions or events since that notification that management believes have changed the Bank’s categorization.

Final 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, and fully phased in by January 1, 2019. The most significant of the provisions of the Final Capital Rules, which applied to the Company and the Bank were 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. Under the Basel III rules, the Company must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer increased by 0.625% each year from 0.00% for 2015 to 2.50% in 2019. The capital conservation buffer for 2019 is 2.50% and for 2018 is 1.875%. The net unrealized gain or loss on available-for-sale securities is not included in computing regulatory capital.

94

As defined in applicable regulations and set forth in the table below, which excludes the capital conservation buffer, at December 31, 2018 and 2017, the Company and the Bank continue to exceed the “well capitalized” standards as well as exceed the Basel III minimum capital ratios of the conservation buffer for each of the risk-based capital ratios:

Unrealized gains and losses on investment securities available-for-sale are recognized in stockholders’ equity as accumulated other comprehensive income or loss. At December 31, 2018, the Company had accumulated other comprehensive loss of $7.9 million, or $5.6 million net of tax, compared to accumulated other comprehensive income of $646,000 or $415,000 net of tax, at December 31, 2017. 

At December 31, 2018, mortgage-backed securities with an estimated par value of $20.3 million and a fair value of $20.9 million were pledged as collateral for the Bank’s HOA reverse repurchase agreements, which totaled $75,000. The average balance of repurchase agreement facilities was $15.0 million during the year ended December 31, 2018.

96

At December 31, 2018 and 2017, 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, meaning: (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 shall be considered to have occurred. If an OTTI occurs, the cost basis of the security will be written down to its fair value as the new cost basis and the write down accounted for as a realized loss. There were no OTTI as of December 31, 2018 and 2017. As of December 2016, the Company realized OTTI losses net of recoveries of $205,000.

The Company originates SBA loans with the intent to sell the guaranteed portion of the loan prior to maturity and, therefore, designates them as held for sale. From time to time, the Company may purchase or sell other types of loans in order to manage concentrations, maximize interest income, change risk profiles, improve returns and generate liquidity.

100

Concentration of Credit Risk

The Company’s loan portfolio was collateralized by various forms of real estate and business assets located principally in California, as well as in certain markets in the states of Arizona, Nevada, and Washington where we also have depository offices. The Company’s loan portfolio contains concentrations of credit in commercial non-owner occupied real estate, multi-family real estate and commercial owner occupied business loans. The Company maintains policies approved by the board of directors that address these concentrations and continues to diversify its loan portfolio through loan originations and purchases and sales of loans to meet approved concentration levels. While management believes that the collateral presently securing these loans is adequate, there can be no assurances that significant deterioration in the California real estate market and economy would not expose the Company to significantly greater credit risk.

Loans Serviced for Others

The Company generally retains the servicing rights of the guaranteed portion of SBA loans sold, for which the Company records a servicing asset at fair value and subsequently accounted for at the lower of cost or market value. At December 31, 2018 and 2017, the servicing asset total $8.5 million and $8.8 million, respectively, and was included in other assets. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is recognized through a valuation allowance, to the extent the fair value is less than the carrying amount. At December 31, 2018, and 2017, the Company determined that no valuation allowance was necessary.

Loans serviced for others are not included in the accompanying consolidated statements of financial condition. The unpaid principal balance of loans and participations serviced for others were $635.3 millionDecember 31, 2018 and $634.5 million at December 31, 2017.

101

Purchased Credit Impaired Loans

The Company has purchased loans through the bank acquisitions, for which there was evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. The carrying amount of those loans at December 31, 2018 and 2017 was as follows:

The Company considers a loan to be impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement or it is determined that the likelihood of the Company receiving all scheduled payments, including interest, when due is remote. The Company has no commitments to lend additional funds to debtors whose loans have been impaired.

The Company reviews loans for impairment when the loan is classified as substandard or worse, delinquent 90 days, determined by management to be collateral dependent, or when the borrower files bankruptcy or is granted a troubled debt restructure. Measurement of impairment is based on the loan’s expected future cash flows discounted at the loan’s effective interest rate, measured by reference to an observable market value, if one exists, or the fair value of the collateral if the loan is deemed collateral dependent. Loans are generally charged-off at the time that 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.

We sometimes modify or restructure loans when the borrower is experiencing financial difficulties by making a concession to the borrower in the form of changes in the amortization terms, reductions in the interest rates, the acceptance of interest only payments and, in limited cases, concessions to the outstanding loan balances. These loans are classified as troubled debt restructurings (“TDRs”) and considered impaired loans. TDRs are loans modified for the purpose of alleviating temporary impairments to the borrower’s financial condition or cash flows. A workout plan between us and the borrower is designed to provide a bridge for borrower cash flow shortfalls in the near term. A TDR loan may be returned to accrual status when the loan is brought current, has performed in accordance with the contractual restructured terms for a time frame of at least six months, and the ultimate collectability of the total contractual restructured principal and interest in no longer in doubt. At December 31, 2018, the Company had no recorded investment in a TDR compared to $97,000 at December 31, 2017.

When loans are placed on nonaccrual status, all accrued interest is reversed from current period 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 six 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 $4.9 million, $3.3 million and $1.1 million at December 31, 2018, 2017 and 2016, respectively. The Company did not record income from the receipt of cash payments related to nonaccruing loans during the years ended December 31, 2018, 2017 and 2016. The Company had $213,000 of loans 90 days or more past due and still accruing at December 31, 2018, all of which were PCI loans. Income recognition for PCI loans is accounted for in accordance with ASC Subtopic 310-30 Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality. The Company had $1.8 million in loans 90 days or more past due and still accruing at December 31, 2017.

Credit Quality and Credit Risk

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 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 and portfolio managers ensure all key risk factors are analyzed with most loan underwriting including a comprehensive global cash flow analysis. 

104

Credit risk is monitored and 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, P1 - P5 and Watch; along with Special Mention, Substandard, Doubtful and Loss classifications, as such classifications are defined by the federal banking 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 probable incurred 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.

• 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 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 or biannual 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.

5.  Allowance for Loan Losses

The Company’s ALLL covers estimated credit losses on individually evaluated loans that are determined to be impaired as well as estimated probable incurred losses inherent in the remainder of the loan portfolio. The ALLL is prepared using the information provided by the Company’s credit review process together with data from peer institutions and economic information gathered from published sources.

107

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 historical loss rates adjusted for current portfolio trends, economic conditions, and other relevant internal and external factors, is applied to each group’s aggregate loan balances.

The Company’s base ALLL factors are determined by management using the Bank’s annualized actual trailing charge-off data over a full credit cycle with an approximate average loss emergence period of1.4 years. Potential adjustments to those base factors are made for relevant internal and external factors. Those factors may include:

• Changes in lending policies and procedures, including underwriting standards and collection, charge-offs, and recovery practices;

• Changes in the nature and volume of the loan portfolio , as well as new types of lending;

• Changes in the experience, ability, and depth of lending management and other relevant staff that may have an impact on our loan portfolio;

• Changes in the volume and severity of adversely classified or graded loans;

• Changes in the quality of our loan review system and the management oversight;

• The existence and effect of any concentrations of credit and changes in the level of such concentrations;

• Changes in national, regional and local economic conditions, including trends in real estate values and the interest rate environment;

• Changes in the value of the underlying collateral for collateral-dependent loans; and

The effect of external factors, such as competition, legal developments and regulatory requirements on the level of estimated credit losses in our current loan portfolio

For loans risk graded as watch or worse, progressively higher potential loss factors are applied based on migration analysis of risk grading and net charge-offs.

9. Bank Owned Life Insurance

At December 31, 2018 and 2017, the Company had $110.9 million and $76.0 million, respectively of BOLI. The Company recorded noninterest income associated with the BOLI policies of $3.4 million, $2.3 million and $1.4 million for the years ending December 31, 2018, 2017 and 2016, respectively.

BOLI involves the purchasing of life insurance by the Company on a select group of employees where the Company is the owner and beneficiary of the policies. BOLI is recorded as an asset at its cash surrender value. Increases in the cash surrender value of these policies, as well as a portion of the insurance proceeds received, are recorded in noninterest income and are not subject to income tax, as long as they are held for the life of the covered parties.

10. Qualified Affordable Housing Project Investments

The Company’s investment in Qualified Affordable Housing Funds that generate Low Income Housing Tax Credits at December 31, 2018 and 2017 was $39.4 million and $11.6 million, respectively, recorded in other assets. Total unfunded commitments related to the investments in qualified affordable housing funds totaled $13.4 million and $1.3 million at December 31, 2018 and 2017, respectively. The Company has invested in five separate LIHTC funds, which provide the Company with CRA credit. Additionally, the investment in LIHTC funds provide the Company with tax credits and with operating loss tax benefits over an approximately 10 year period. None of the original investment will be repaid. The investments in the WNC Institutional Tax Credit funds are being accounted for using the cost method, under which the Company amortizes as non-interest expense the initial cost of the investment equally over the expected time period in which tax credits and other tax benefits will be received. The investments in the Sycamore Court, R4 CA Housing and Cypress Cove funds qualify for and are being accounted for using the proportional amortization method, which allows for the amortization of the investments to be in proportion to the total of the tax credits and other tax benefits that are allocated to the investor. The tax credits and operating loss tax benefits are recognized in the income statement as a component of income tax expense (benefit) for all LIHTC funds.

In August 2014, the Corporation issued $60.0 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 $50.0 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%, with the first interest payment on the Notes occurring on March 3, 2015, and interest to be paid semiannually each March 3 and September 3 through September 3, 2024. At December 31, 2018, the carrying value of the Notes was $59.3 million, net of unamortized debt issuance costs of $688 thousand. The Notes can only be redeemed, in whole or in part, 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). As of December 31, 2018, the Notes qualify as Tier 2 Capital. Principal and interest are due upon early redemption.

In connection with the Private Placement, the Corporation obtained ratings from Kroll Bond Rating Agency (“KBRA”). KBRA assigned investment grade ratings of BBB+ and BBB for the Corporation’s senior unsecured debt and subordinated debt, respectively, and a deposit rating of A- for the Bank. The Company’s and Bank’s ratings were reaffirmed in October 2018 by KBRA.

In March 2004, the Corporation issued $10.3 million in Floating Rate Junior Subordinated Deferrable Interest Debentures (the “Subordinated Debentures”) to PPBI Trust I, a statutory trust created under the laws of the State of Delaware. The Debt Securities are subordinated to effectively all borrowings of the Corporation and are due and payable on April 6, 2034. Interest is payable quarterly on the Subordinated Debentures at three-month LIBOR plus 2.75% per annum, for an effective rate of 5.19% as of December 31, 2018. The Subordinated Debentures may be redeemed, in part or whole, on or after April 7, 2009 at the option of the Corporation, at par. The Subordinated Debentures can also be redeemed at par if certain events occur that impact the tax treatment or the capital treatment of the issuance. The Corporation also purchased a 3% minority interest totaling $310,000 in PPBI Trust I. The balance of the equity of PPBI Trust I is comprised of mandatorily redeemable preferred securities (“Trust Preferred Securities”) and is included in other assets. PPBI Trust I sold $10.0 million of Trust Preferred Securities to investors in a private offering.

On April 1, 2017, as part of the HEOP acquisition, the Corporation assumed $5.2 million of floating rate junior subordinated debt securities associated with Heritage Oaks Capital Trust II. Interest is payable quarterly at three-month LIBOR plus 1.72% per annum, for an effective rate of 4.12% per annum as of December 31, 2018. At December 31, 2018, the carrying value of these debentures was $4.0 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 December 31, 2018, the carrying value of Mission Community Capital Trust I and Santa Lucia Bancorp (CA) Capital Trust were $2.8 million and $3.8 million, respectively, which reflects purchase accounting fair value adjustments of $306,000 and $1.3 million, respectively. Interest is payable quarterly at three-month LIBOR plus 2.95% per annum, for an effective rate of 5.39% per annum as of December 31, 2018 for Mission Community Capital Trust I. Interest is payable quarterly at three-month LIBOR plus 1.48% per annum, for an effective rate of 3.92% per annum as of December 31, 2018 for Santa Lucia Bancorp (CA) Capital Trust.

The notes have a maturity date of June 26, 2025 and are also redeemable in whole, or in part, from time to time beginning in June 26, 2020 at an amount equal to 103.0% of principal plus accrued unpaid interest. The redemption price decreases 50 basis points each subsequent year. At December 31, 2018, the carrying value of these subordinated notes was $25.2 million, which reflects purchase accounting fair value adjustments of $157,000.

On July 1, 2018, as part of the Grandpoint acquisition, the Corporation assumed $5.2 million of floating rate junior subordinated debt securities associated with First Commerce Bancorp Statutory Trust I. Interest is payable quarterly at three-month LIBOR plus 2.95% per annum, for an effective rate of 5.74% per annum as of December 31, 2018.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (“Tax Act”). Among other changes, the Tax Act reduces the U.S. federal corporate tax rate from 35% to 21%. The Company performed an initial assessment and reasonably estimated the effects of the Tax Act on its deferred tax amounts to be approximately $5.6 million, which was recorded as a charge to income tax expense in the fourth quarter of 2017, in accordance with SEC Staff Accounting Bulletin No. 118 (“SAB 118”). As required by SAB 118, the Company continued to reassess and refine the effects of the Tax Act on its deferred tax amounts during 2018. As a result, the Company recorded an income tax benefit of $1.4 million during the year ended December 31, 2018. As of December 31, 2018, the Company has completed the accounting for the income tax effects of the Tax Act.

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 forecasts of future income, applicable tax planning strategies, and assessments of current and future economic and business conditions. This analysis is updated quarterly and adjusted as necessary. Based on the analysis, the Company has determined that a valuation allowance for deferred tax assets was not required as of December 31, 2016 and December 31, 2018. As of December 31, 2017, the Company recorded a valuation allowance of $380,000 against the capital loss carryover deferred tax asset, as the Company does not believe it will generate sufficient capital gain before the capital loss carryover expires.

Section 382 of the Internal Revenue Code imposes limitations on a corporation’s ability to use any net unrealized built in losses and other tax attributes, such as net operating loss and tax credit carryforwards, when it undergoes a 50% ownership change over a designated testing period. The Company has a Section 382 limited net operating loss carry forward of approximately $25.7 million for federal income tax purposes, which is scheduled to expire in 2026. In addition, the Company has a Section 382 limited net operating loss carry forward of approximately $8.9 million for California franchise tax purposes, which is scheduled to expire in 2020. The Company is expected to fully utilize the federal and California net operating loss carryforward before it expires with the application of the Section 382 annual limitation.

The Company and its subsidiaries are subject to U.S. Federal income tax as well as income and franchise tax 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 2013. The expiration of the statute of limitations related to the various state income and franchise tax returns varies by state. The Company is currently not under examination in any taxing jurisdiction.

A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2018 and 2017 is as follows:

	2018		2017
	(dollars in thousands)
Balance at January 1,	$	2,906	$	—
Additions based on tax positions related to prior years	—		2,906
Balance at December 31,	$	2,906	$	2,906

The total amount of unrecognized tax benefits was $2.9 million and $2.9 million at December 31, 2018 and 2017, respectively, and is primarily comprised of unrecognized tax benefits from an acquisition during 2017. The total amount of tax benefits that, if recognized, would favorably impact the effective tax rate was $0 at December 31, 2018. The Company does not believe that the unrecognized tax benefits will change within the next twelve months.

The Company recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense. The Company had accrued for $246,000 and $104,000 of the interest and penalties at December 31, 2018 and 2017, respectively.

15. Commitments, Contingencies and Concentrations of Risk

Lease Commitments – The Company leases a portion of its facilities from non-affiliates under operating leases expiring at various dates through 2028. The following schedule shows the minimum annual lease payments, excluding any renewals and extensions, property taxes, and other operating expenses, due under these agreements:

Year ending December 31,	Amount
	(dollars in thousands)
2019	$	11,468
2020	10,869
2021	10,133
2022	9,296
2023	8,124
Thereafter	10,518
Total	$	60,408

Rental expense under all operating leases totaled $9.2 million for 2018, $4.8 million for 2017, and $4.4 million for 2016.

Legal Proceedings –-The Company is not involved in any material pending legal proceedings other than legal proceedings occurring in the ordinary course of business. Management believes that none of these legal proceedings, individually or in the aggregate, will have a material adverse impact on the results of operations or financial condition of the Company.

Employment Agreements—The Company has entered into a three-year employment agreement with its Chief Executive Officer (“CEO”). This agreement provides for the payment of a base salary, a bonus based upon the CEO’s individual performance and the Company’s overall performance, provides a vehicle for the CEO’s use, and provides for the payment of severance benefits upon termination under specified circumstances.  

Additionally, the Bank has entered into three-year employment agreements with each of the following executive officers: the Bank’s President and Chief Operating Officer, the Chief Credit Officer and Chief Innovation Officer. The agreements provide for the payment of a base salary, a bonus based upon the individual’s performance and the overall performance of the Bank, and the payment of severance benefits upon termination under specified circumstances.

Availability of Funding Sources. The Company funds substantially all of the loans thatit originates or purchases through deposits, internally generated funds and/or borrowings. The Company competes for deposits primarily on the basis of rates, and, as a consequence, the Company could experience difficulties in attracting deposits to fund its operations if the Company does not continue to offer deposit rates at levels that are competitive with other financial institutions. To the extent that the Company is not able to maintain its currently available funding sources or to access new funding sources, it would have to curtail its loan production activities or sell loans and investment securities earlier than is optimal. Any such event could have a material adverse effect on the Company’s results of operations, financial condition and cash flows.

The 2012 Plan authorizes the granting of Awards equal to 620,000 shares of the common stock of the Corporation for issuances to executives, key employees, officers, and directors. The 2012 Plan will be in effect for a period of ten years from May 30, 2012, the date the 2012 Plan was adopted. Awards granted under the 2012 Plan will be made at an exercise price equal to the fair market value of the stock on the date of grant. Awards granted to officers and employees may include incentive stock options, non-qualified stock options, restricted stock, restricted stock units, and stock appreciation rights. The awards have vesting periods ranging from one to three years, where such vesting may occur in either three equal annual installments or one lump sum at the end of the third year. In May 2014, the Corporation’s stockholders approved an amendment to the 2012 Plan to increase the shares available under the plan by 800,000 shares to total 1,420,000 shares. In May 2015, the Corporation’s stockholders approved an amendment to the 2012 Plan to permit the grant of performance-based awards, including equity compensation awards that may not be subject to the deduction limitation of Section 162(m) of the Internal Revenue Code. The performance-based awards include (i) both performance-based equity compensation awards and performance-based cash bonus payments and (ii) restricted stock units. In May 2017, the Corporation’s stockholders approved an amendment to the 2012 Plan to increase the shares available under the plan by 3,580,000 shares to total 5,000,000 shares.

Heritage Oaks Bancorp, Inc. 2015 Equity Based Compensation Plan (the “2015 Plan”). The 2015 Plan was acquired from Heritage Oaks Bancorp, Inc. on April 1, 2017. The 2015 plan was approved by the Corporation’s stockholders in May 2015. The 2015 Plan authorized the Company to grant various types of share-based compensation awards to the Company’s employees and Board of Directors such as stock options, restricted stock awards, and restricted stock units. Under the 2015 Equity Incentive Plan a maximum of 2,500,000 shares of the Company’s common stock were made to be issued. Shares issued under this plan, other than stock options and stock appreciation rights, were counted against the plan on a two shares for every one share actually issued basis. Awards that were canceled, expired, forfeited, fail to vest, or otherwise resulted in issued shares not being delivered to the grantee, were made available for the issuance of future share-based compensation awards. Additionally, under this plan, no one individual was to be granted shares in aggregate that exceed more than 250,000 shares during any calendar year. The 2015 Plan is still active and Pacific Premier assumed all unvested and unexercised awards.

Other Plans

Salary Continuation Plan. The Bank implemented a non-qualified supplemental retirement plan in 2006 (the “Salary Continuation Plan”) for certain executive officers of the Bank. The Salary Continuation Plan is unfunded.

Deferred Compensation Plans. The Bank implemented a non-qualified supplemental retirement plan in 2006 (the “Supplemental Executive Retirement Plan” or “SERP”) for certain executive officers of the Bank. The Bank has acquired additional SERPs through the acquisitions of San Diego Trust Bank (“SDTB”), Independence Bank (“IDPK”) and HEOP. The SERP is unfunded. The expense incurred for the SERP for each of the last three years was $827,000, $721,000 and $573,000 resulting in a deferred compensation liability of $10.9 millionand $8.3 million as of the years ended 2018 and 2017. In addition, with the acquisition of PLZZ, the Company acquired a deferred compensation plan that is unfunded and results in a deferred compensation asset and liability both in the amount of $1.6 million and $2.0 million as of the years ended 2018 and 2017.

The amounts expensed in 2018, 2017 and 2016 for all of these plans amounted to $827,000, $721,000 and $573,000 respectively. As of December 31, 2018, 2017 and 2016, $10.9 million, $8.4 million, and $5.7 million, respectively, were recorded in other liabilities on the consolidated statements of condition for each of these plans.

17. Financial Instruments with Off-Balance Sheet Risk

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit in the form of originating loans or providing funds under existing lines or letters of credit. These commitments are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates and may require payment of a fee. Since many commitments are expected to expire, the total commitment amounts do not necessarily represent future cash requirements. Commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the accompanying consolidated statements of financial condition.

The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual or notional amount of those instruments. The Company controls credit risk of its commitments to fund loans through credit approvals, limits and monitoring procedures. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company evaluates each customer for creditworthiness.

The Company receives collateral to support commitments when deemed necessary. The most significant categories of collateral include real estate properties underlying mortgage loans, liens on personal property and cash on deposit with the Bank.

The Company maintains an allowance for credit losses to provide for commitments related to loans associated with undisbursed loan funds and unused lines of credit. The allowance for these commitments was $4.6 million at December 31, 2018 and $1.9 million at December 31, 2017. The change in the allowance for credit losses for unfunded commitments during the year ended December 31, 2018 was attributable to $2.6 million in fair value adjustments associated unfunded loan commitments and unused lines of credit assumed through the acquisitions of Grandpoint and HEOP. These fair value adjustments were made within the one-year measurement period associated with each acquisition and are attributed to the fair value of unfunded loan commitments and unused lines of credit assumed at the acquisition date.

The Company’s commitments to extend credit at December 31, 2018 were $1.8 billion and $1.2 billion at December 31, 2017. The 2018 balance is primarily composed of $1.1 billion of undisbursed commitments for C&I loans.

18. Fair Value of Financial Instruments

The fair value of an asset or liability is the exchange price that would be received to sell that asset or paid to transfer that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach, and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including both those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis and a non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value, 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 December 31, 2018 and December 31, 2017.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management maximizes the use of observable inputs and attempts to minimize the use of unobservable inputs when determining fair value measurements. Estimated fair values are disclosed for financial instruments for which it is practicable to estimate fair value. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains

129

and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates.

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.

Investment securities. Investment securities are generally valued based upon quotes obtained from an independent third-party pricing service, 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.

Impaired Loans and Other Real Estate Owned. A loan is considered impaired when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Impairment is measured based on the fair value of the underlying collateral or the discounted expected future cash flows. The Company measures impairment on all 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 December 31, 2018, substantially all the Company’s impaired loans were evaluated based on the fair value of their underlying collateral based upon the most recent appraisal available to management and has recorded a specific reserve on one loan in the amount of $584,000 with a principal balance of $1.0 million.

The fair value of impaired loans and other real estate owned were determined using Level 3 assumptions, and represents impaired loan and other real estate owned balances for which a specific reserve has been established or on which a write down has been taken. Generally, the Company obtains third party appraisals (or property valuations) and/or collateral audits in conjunction with internal analysis based on historical experience on its impaired loans and other real estate owned to determine fair value. In determining the net realizable value of the underlying collateral for impaired loans, the Company will then discount the valuation to cover both market price fluctuations and selling costs the Company expected would be incurred in the event of foreclosure. In addition to the discounts taken, the Company’s calculation of net realizable value considered any other senior liens in place on the underlying collateral.

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 non-recurring Level 3 when the fair value of the underlying collateral is based on an observable market price or current appraised value. When current market prices are not available or the Company determines that the fair value of the underlying collateral is further impaired below appraised values, the Company records impaired loans as Level 3. At December 31, 2018, substantially all the Company’s impaired loans were evaluated based on the fair value of their underlying collateral based upon the most recent appraisal available to management.

The measures of fair value on a non-recurring basis are immaterial at December 31, 2018 and 2017. The following fair value hierarchy tables present information about the Company’s assets measured at fair value on a recurring basis at the dates 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.

19. Earnings Per Share

Earnings per share of common stock is calculated on both a basic and diluted basis based on the weighted average number of common and common equivalent shares outstanding, excluding common shares in treasury. Basic earnings per share excludes potential dilution and is computed by dividing income available to stockholders by the weighted average number of common shares outstanding for the period. The Company has no outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends that would be considered participating securities for the basic calculation. 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 then would 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. There are no anti-dilutive stock options at December 31, 2018. The weighted average number of stock options excluded was for 17,524 for December 31, 2017 and 82,760 for December 31, 2016.

A reconciliation of the numerators and denominators used in basic and diluted earnings per share computations is presented in the table below.

20. 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 December 31, 2018, the Company had swaps with matched terms with an aggregate notional amount

134

of $57.5 million and a fair value of $1.7 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 and net to zero 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 twelve months ended December 31, 2018, there were no losses recorded on swap agreements, attributable to the change in credit risk associated with a counterparty. All interest rate swap agreements entered into by the Company as of December 31, 2018 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 2017 HEOP acquisition, and the Company did not have any at December 31, 2016:

21. 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.

22. Revenue Recognition

The Company earns revenue from a variety of sources. The Company’s principal source of revenue is interest income on loans, investment securities and other interest earning assets, while the remainder of the Company’s revenue is earned from a variety of fees, service charges, gains and losses, and other income, all of which are classified as noninterest income. Revenue from interest on loans and investment securities is accounted for on an accrual basis using the interest method, while revenue from other sources is accounted for under other applicable U.S. GAAP as well as ASC 606 - Revenue from Contracts with Customers. Revenue streams within the scope of and accounted for under ASC 606 include: service charges and fees on deposit accounts, debit card interchange fees, fees from other services the Company provides its customers and gains and losses from the sale of other real estate owned and property, premises and equipment. ASC 606 requires revenue to be recognized when the Company satisfies the related performance obligations by transferring to the customer a good or service. The recognition of revenue under ASC 606 requires the Company to first identify the contract with the customer, identify the associated performance obligations, determine the transaction price, allocate the transaction price to the performance obligations and finally recognize revenue when the performance obligations have been satisfied and the good or service has been transferred. The majority of the Company’s contracts with customers associated with revenue streams that are within the scope of ASC 606 are considered short-term in nature and can be canceled at any time by the customer or the Company without penalty, such as a deposit account agreement. These revenue streams are included in non-interest income.

The following table provides a summary of the Company’s revenue streams, including those that are within the scope of ASC 606 and those that are accounted for under other applicable U.S. GAAP:

______________________________

⁽¹⁾ Revenues from contracts with customers accounted for under ASC 606.

⁽²⁾ Revenues not within the scope of ASC 606 and accounted for under other applicable U.S. GAAP requirements.

The following provides information concerning the major components of the Company’s revenue:

Interest Income. Interest income is comprised of interest on loans, investment securities and other interest-earning assets. Interest is recognized using the interest method, which reflects the contractual yield on loans and coupon yield for investment securities. These yields are adjusted for purchase discounts, premiums and net deferred loan origination fees for newly originated loans.

Loan Servicing Fees. Loan servicing fees generally consist of fees related to servicing of loans for others, as well as the net impact of related serving asset amortization. ASC 606 stipulates that income streams generated through the transfer and servicing of financial instruments shall be accounted for under ASC 860 - Transfers and Servicing and is therefore excluded from the scope of ASC 606.

Service Charges on Deposit Accounts and Other Service Fee Income. Service charges on deposit accounts and other service fee income consists of periodic service charges on deposit accounts and transaction based fees such as those related to overdrafts, ATM charges and wire transfer fees. The majority of these revenues are accounted for under ASC 606. Performance obligations for periodic service charges on deposit accounts are typically short-term in nature and are generally satisfied on a monthly basis, while performance obligations for other transaction based fees are typically satisfied at a point in time (which may consist of only a few moments to perform the service or transaction) with no further obligations on behalf of the Company to the customer. Periodic service charges are generally collected monthly directly from the customer’s deposit account, and at the end of a

138

statement cycle, while transaction based service charges are typically collected at the time of or soon after the service is performed.

Debit Card Interchange Income. Debit card interchange fee income consists of transaction processing fees associated with customer debit card transactions processed through a payment network and are accounted for under ASC 606. These fees are earned each time a request for payment is originated by a customer debit cardholder at a merchant. In these transactions, the Company transfers funds from the debit cardholder’s account to a merchant through a payment network at the request of the debit cardholder by way of the debit card transaction. The related performance obligations are generally satisfied when the transfer of funds is complete, which is generally a point in time when the debit card transaction is processed. Debit card interchange fees are typically received and recorded as revenue on a daily basis.

Earnings on Bank Owned Life Insurance. Earnings on BOLI relate to the periodic increase in the cash surrender value of BOLI policies on certain key employees of the Company for which the Company is the owner and beneficiary of the related policies. This revenue stream is excluded from the scope of ASC 606, and is accounted for under other applicable U.S. GAAP provisions (ASC 325-30).

Gains and (Losses) from Sales of Loans and Investment Securities. ASC 606 stipulates that gains and (losses) from the periodic sale of loans and investment securities are excluded from ASC 606 and are accounted for under other applicable U.S. GAAP provisions.

Other Income. Other income generally consists of recoveries on acquired loans, which were fully charged off and had no book value prior to their acquisition, as well as other miscellaneous loan fees, and rental income from various subleases. These revenue streams are excluded from the scope of ASC 606 and are accounted for under other applicable U.S. GAAP provisions. Other income also consists of other miscellaneous fees, which are accounted for under ASC 606; however, much like service charges on deposit accounts, these fees have performance obligations that are very short-term in nature and are typically satisfied at a point in time. Revenue is typically recorded at the time these fees are collected, which is generally upon the completion the related transaction or service provided.

Other revenue streams that may be applicable to the Company include gains and losses from the sale of non-financial assets such as other real estate owned and property premises and equipment. The Company accounts for these revenue streams in accordance with ASC 610-20, which requires the Company to look to guidance in ASC 606 in the application of certain measurement and recognition concepts. The Company records gains and losses on the sale of non-financial assets when control of the asset has been surrendered to the buyer, which generally occurs at a specific point in time.

Practical Expedient. The Company also employs a practical expedient with respect to contract acquisition costs, which are generally capitalized and amortized into expense. These costs relate to expenses incurred directly attributable to the efforts to obtain a contract. The practical expedient allows the Company to immediately recognize contract acquisition costs in current period earnings when these costs would have been amortized over a period of one year or less.

At December 31, 2018 the Company did not have any material contract assets or liabilities in its consolidated financial statements related to revenue streams within the scope of ASC 606, and there were no material changes in those balances during the reporting period.

23. Related Parties

Goodwill recognized in this transaction is not deductible for income tax purposes.

The following table represents the SCAF assets acquired and liabilities assumed as of January 31, 2016 and the fair value adjustments and amounts recorded by the Company under the acquisition method of accounting:

The Company accounted for these transactions under the acquisition method of accounting in accordance with ASC 805, Business Combinations, which requires purchased assets and liabilities assumed to be recorded at their respective fair values at the date of acquisition.

The loan portfolios of Grandpoint, PLZZ, HEOP and SCAF were recorded at fair value at the date of each acquisition. The valuation of loan portfolios of Grandpoint, PLZZ, HEOP and SCAF’s were performed as of the acquisition dates to assess their fair values. The loan portfolios were split into two groups: loan with credit deterioration and loans without credit deterioration, and then segmented further by loan type. The fair value was calculated on an individual loan basis using a discounted cash flow analysis. The discount rate utilized was based on a weighted average cost of capital, considering the cost of equity and cost of debt. Also factored into the fair value estimates were loss rates, recovery period and prepayment rates based on industry standards.

For loans acquired from Grandpoint, PLZZ, HEOP and SCAF, the contractual amounts due, expected cash flows to be collected, interest component and fair value as of the respective acquisition dates were as follows:

	Acquired Loans
	Grandpoint		PLZZ		HEOP		SCAF
	(dollars in thousands)
Contractual amounts due	$	3,496,905	$	1,708,685	$	1,717,230	$	539,806
Cash flows not expected to be collected	39,071		20,152		4,442		2,765
Expected cash flows	3,457,834		1,688,533		1,712,788		537,041
Interest component of expected cash flows	1,105,117		625,632		348,100		80,883
Fair value of acquired loans	$	2,352,717	$	1,062,901	$	1,364,688	$	456,158

146

In accordance with generally accepted accounting principles, there was no carryover of the allowance for loan losses that had been previously recorded by Grandpoint, PLZZ, HEOP and SCAF.

The Company also determined the fair value of the core deposit intangible, securities and deposits with the assistance of third-party valuations and determined the fair value of OREO from recent appraisals of the properties less estimated costs to sell. Since the fair value of intangible assets is calculated as if they were stand-alone assets, the presumption is that a hypothetical buyer of the intangible asset would be able to take advantage of potential after tax benefits resulting from the asset purchase.

The core deposit intangible on non-maturing deposit represents future benefits arising from savings on source of funding and was determined by evaluating the underlying characteristics of the deposit relationships, including customer attrition, deposit interest rates, service charge income, overhead expense and costs of alternative funding. The value of the after tax savings on cost of fund is the present value over a estimated fifty-year horizon, using the discount rate applicable to the asset.

In determining the fair value of certificates of deposit, a discounted cash flow analysis was used, which involved present valuing the contractual payments over the remaining life of the certificates of deposit at market-based interest rates

The operating results of the Company for the twelve months ending December 31, 2018 include the operating results of Grandpoint, PLZZ, HEOP and SCAF since their respective acquisition dates. The following table presents the net interest and other income, net income and earnings per share as if the merger with Grandpoint, PLZZ, HEOP and SCAF were effective as of January 1, 2016. The unaudited pro forma information in the following table is intended for informational purposes only and is not necessarily indicative of our future operating results or operating results that would have occurred had the mergers been completed at the beginning of each respective year. No assumptions have been applied to the pro forma results of operations regarding possible revenue enhancements, expense efficiencies or asset dispositions.

There were no material, nonrecurring adjustments to the unaudited pro forma net interest and other income, net income and earnings per share presented below:

	Year Ended December 31,
	2018		2017		2016
Net interest and other income	$	473,748	$	465,400	$	378,894

ITEM 9A.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e)) under the Exchange Act as of the end of the period covered by this Annual Report on Form 10-K. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Based on our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective as of the end of the period covered by this Annual Report on Form 10-K in providing reasonable assurance that information we are required to disclose in periodic reports that we file or submit to the SEC pursuant to the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with United States generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that:

• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with United States generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with the authorization of its management and directors; and

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Our management assessed the effectiveness of its internal control over financial reporting as of December 31, 2018. In making this assessment, management used the framework set forth in the report entitled “Internal Control-Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO. The COSO framework summarizes each of the components of a company’s internal control system, including (i) the control environment, (ii) risk assessment, (iii) control activities, (iv) information and communication, and (v) monitoring. Based on this assessment, our management believes that, as of December 31, 2018, our internal control over financial reporting was effective.

Crowe LLP, the independent registered public accounting firm that audited the Company’s financial statements included in the Annual Report, issued an audit report on the Company’s internal control over financial

reporting as of, and for the year ended December 31, 2018. Crowe LLP’s audit report appears in Item 8 of this Annual Report.

Changes in Internal Control over Financial Reporting

We regularly review our system of internal control over financial reporting and make changes to our processes and systems to improve controls and increase efficiency, while ensuring that we maintain an effective internal control environment. Changes may include such activities as implementing new, more efficient systems, consolidating activities, and migrating processes.

There have been no changes in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended December 31, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Description of Business and Summary of Significant Accounting Policies

Description of Business and Summary of Significant Accounting Policies

Description of Business—Pacific Premier Bancorp, Inc., a Delaware corporation organized in 1997 (the “Corporation”), is a California-based bank holding company that owns 100% of the capital stock of Pacific Premier Bank, a California-chartered commercial bank (the “Bank,” and together with the Corporation and its consolidated subsidiaries, the “Company”), the Corporation’s principal operating subsidiary. The Bank was incorporated and commenced operations in 1983.

The principal business of the Company is attracting deposits from the general public and investing those deposits, together with funds generated from operations and borrowings, primarily in business loans and real estate property loans. At December 31, 2018, the Company had 44 depository branches located in the counties of Orange, Los Angeles, Riverside, San Bernardino, San Diego, San Luis Obispo and Santa Barbara, California, as well as Pima and Maricopa Counties, Arizona, Clark County, Nevada and Clark County, Washington. The Company is subject to competition from other financial institutions. The Company is subject to the regulations of certain governmental agencies and undergoes periodic examinations by those regulatory authorities.

Principles of Consolidation—The consolidated financial statements include the accounts of Corporation and its wholly-owned subsidiary the Bank. The Company accounts for its investments in its wholly-owned special purpose entities, PPBI Statutory Trust I, Heritage Oaks Capital Trust II, Mission Community Capital Trust I Santa Lucia Bancorp (CA) Capital Trust and First Commerce Bancorp Statutory Trust I, under the equity method whereby the subsidiary’s net earnings are recognized in the Company’s Statement of Income and the investment in these entities is included in Other Assets on the Company’s Consolidated Statements of Financial Condition. The Company is organized and operates as a single reporting segment, principally engaged in the commercial banking business. All significant intercompany accounts and transactions have been eliminated in consolidation.

Basis of Financial Statement Presentation—The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (‘‘U.S. GAAP’’). Certain amounts in the financial statements and related footnote disclosures for the prior years have been reclassified to conform to the current presentation with no impact to previously reported net income or stockholders’ equity.

Use of Estimates—The preparation of consolidated financial statements in conformity with U.S. GAAP 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, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates may change as new information is obtained.

The following discussion provides a summary of the Company’s significant accounting policies:

Cash and Cash Equivalents—Cash and cash equivalents include cash on hand, cash balances due from banks and federal funds sold. Interest bearing deposits with financial institutions represent primarily cash held at the Federal Reserve Bank of San Francisco. At December 31, 2018, there were no cash reserves required by the Board of Governors of the Federal Reserve System (“Federal Reserve”) for depository institutions based on the amount of deposits held. The Company maintains amounts due from banks that exceed federally insured limits. The Company has not experienced any losses in such accounts.

Securities—The Company has established written guidelines and objectives for its investing activities. At the time of purchase, management designates the security as either held to maturity, available-for-sale or held for trading based on the Company’s investment objectives, operational needs and intent. The investments are monitored to ensure that those activities are consistent with the established guidelines and objectives.

Securities Held-to-Maturity—Investments in debt securities that management has the positive intent and ability to hold to maturity are reported at cost and adjusted for periodic principal payments and the amortization of premiums and accretion of discounts, which are recognized in interest income using the interest method over the period of time to investment’s maturity.

Securities Available-for-Sale—Investments in debt securities that management has no immediate plan to sell, but which may be sold in the future, are carried at fair value. Premiums and discounts are amortized using the interest method over the remaining period to the call date for premiums or contractual maturity for discounts and, in the case of mortgage-backed securities, the estimated average life, which can fluctuate based on the anticipated prepayments on the underlying collateral of the securities. Unrealized holding gains and losses, net of tax, are recorded in a separate component of stockholders’ equity as accumulated other comprehensive income. Realized gains and losses on the sales of securities are determined on the specific identification method, recorded on a trade date basis based on the amortized cost basis of the specific security and are included in noninterest income as net gain (loss) on investment securities.

Impairment of Investments—Quarterly, the Company evaluates investment securities in an unrealized loss position for OTTI. In determining whether a security’s decline in fair value is other-than-temporary, the Company considers a number of factors including: (i) the length of time and the extent to which the fair value of the investment has been less than its amortized cost; (ii) the financial condition and near-term prospects of the issuer; (iii) the intent and ability of the Company to hold the investment for a period of time sufficient to allow for an anticipated recovery in fair value; (iv) downgrades in credit ratings; and (v) general market conditions which reflect prospects for the economy as a whole, including interest rates and sector credit spreads. If it is determined that an OTTI exists, and either the Company intends to sell the investment or it is likely the Company will be required to sell the investment before its anticipated recovery, the total amount of the OTTI, which is measured as the amount by which the investment’s amortized cost exceeds its fair value, is recognized in current period earnings. If the Company has the intent and ability to hold the investment and it is more likely than not it will be required to sell the investment prior to an anticipated recovery of its amortized cost basis, the Company records in current period earnings the portion of OTTI deemed to be credit related, while the remaining portion of OTTI deemed to be non-credit related is recorded in accumulated other comprehensive income. Credit related losses are determined through a discounted cash flow analysis, which incorporates assumptions concerning the estimated timing and amounts of expected cash flows. Non-credit related OTTI losses result from other factors such as change in interest rates and general market conditions. The presentation of OTTI in the consolidated financial statements is on a gross basis with a reduction in the gross amount for the portion of the loss deemed non-credit related and is recorded in accumulated other comprehensive income.

Federal Home Loan Bank Stock—The Bank is a member of the Federal Home Loan Bank System. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are recorded as a component of interest income.

Federal Reserve Bank Stock—The Bank is a member of the Federal Reserve Bank of San Francisco (the “FRB”). FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are recorded as a component of interest income.

Loans Held for Sale—Loans that the Company has the intent to sell prior to maturity have been designated as held for sale at origination and are recorded at lower of cost or fair value. Gains or losses are recognized upon the sale of the loans on a specific identification basis.

Loan Servicing Assets—Servicing assets are related to SBA loans sold and are recognized at the time of sale when servicing is retained with the income statement effect recorded in gains on sales of SBA loans. Servicing assets are initially recorded at fair value based on the present value of the contractually specified servicing fee, net of estimated servicing costs, over the estimated life of the loan, using a discount rate. The Company’s servicing costs approximates the industry average servicing costs of approximately 40 basis points. The servicing assets are subsequently amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. The Company periodically evaluates servicing assets for impairment based upon the fair value of the assets as compared to their carrying amount.

The Company typically sells the guaranteed portion of SBA loans and retains the unguaranteed portion (“retained interest”). A portion of the premium on sale of SBA loans is recognized as gain on sale of loans at the time of the sale by allocating the carrying amount between the asset sold and the retained interest, based on their relative fair values. The remaining portion of the premium is recorded as a discount on the retained interest and is amortized over the remaining life of the loan as an adjustment to yield. The retained interest, net of any discount, are included in loans held for investment—net of allowance for loan losses in the accompanying consolidated statements of financial condition.

Loans Held for Investment—Loans held for investment are loans the Company has the ability and intent to hold until their maturity. The loans are carried at amortized cost, net of discounts and premiums on purchased loans, deferred loan origination fees and costs and ALLL. Net deferred loan origination fees and costs on loans are amortized or accreted using the interest method over the expected life of the loans. Amortization of deferred loan fees and costs are discontinued for loans placed on nonaccrual. Any remaining deferred fees or costs and prepayment fees associated with loans that payoff prior to contractual maturity are included in loan interest income in the period of payoff. Loan commitment fees received to originate or purchase a loan are deferred and, if the commitment is exercised, recognized over the life of the loan using the interest method as an adjustment of yield or, if the commitment expires unexercised, recognized as income upon expiration of the commitment.

Interest on loans is recognized using the interest method and is only accrued if deemed collectible. Loans for which the accrual of interest has been discontinued are designated as nonaccrual loans. The accrual of interest on loans is discontinued when principal or interest is past due 90 days based on contractual terms of the loan or when, in the opinion of management, there is reasonable doubt as to collection of principal and or interest. When loans are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Interest income generally is not recognized on nonaccrual loans unless the likelihood of further loss is remote. Interest payments received on nonaccrual loans are applied as a reduction to the loan principal balance. Interest accruals are resumed on such loans only when they are brought current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to all principal and interest.

A loan is considered to be impaired when it is probable that the Company will be unable to collect all amounts due (principal and interest) according to the contractual terms of the loan agreement. The Company reviews loans for impairment when the loan is classified as substandard or worse, delinquent 90 days, determined by management to be collateral dependent, or when the borrower files bankruptcy or is granted concession which qualifies as a troubled debt restructuring. 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. The Company selects the measurement method on a loan-by-loan basis except those loans deemed collateral dependent. Loans for which impairment has been determined are generally charged-off at such time the loan is classified as a loss.

Allowance for Loan Losses—The Company maintains an ALLL at a level deemed appropriate by management to provide for known or probable incurred losses in the portfolio as of the date of the consolidated statements of financial condition. The Company has an internal loan review system and loss allowance methodology designed to provide for the detection of problem loans and an appropriate level of allowance to cover loan losses. Management’s determination of the adequacy of the ALLL is based on an evaluation of the composition of the portfolio, actual loss experience, industry charge-off experience on income property loans, current economic conditions, and other relevant factors in the area in which the Company’s lending and real estate activities are based. These factors may affect the borrower’s ability to pay as well as the value of the underlying collateral securing loans. The allowance is calculated by applying loss factors to loans held for investment according to loan type and loan credit classification. The loss factors are based primarily upon the Bank’s historical loss experience and industry charge-off experience, and are evaluated on a quarterly basis.

At December 31, 2018, the following portfolio segments have been identified. Segments are groupings of similar loans at a level, for which the Company has adopted systematic methods of documentation for determining its allowance for loan losses:

• Commercial and industrial (including Franchise) - Commercial and industrial (“C&I”) loans are secured by business assets including inventory, receivables and machinery and equipment to businesses located generally in our primary market area. Loan types includes revolving lines or credit, term loans, seasonal loans and loans secured by liquid collateral such as cash deposits or marketable securities. Homeowners’ Association (“HOA”) credit facilities are included in C&I loans. We also issue letters of credit on behalf of our customers. Risk arises primarily due to the difference between expected and actual cash flows of the borrowers. In addition, the recoverability of the Company’s investment in these loans is also dependent on other factors primarily dictated by the type of collateral securing these loans. The fair value of the collateral securing these loans may fluctuate as market conditions change. In the case of loans secured by accounts receivable, the recovery of the Company’s investment is dependent upon the borrower’s ability to collect amounts due from its customers.

• Commercial real estate (including owner-occupied and nonowner occupied) - Commercial real estate (“CRE”) includes various type of loans which the Company holds real property as collateral. CRE lending activity is typically restricted to owner-occupied or nonowner-occupied. The primary risks of real estate loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make the real estate loan unprofitable to the borrower. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy.

• SBA - We are approved to originate loans under the SBA’s Preferred Lenders Program (“PLP”). The PLP lending status affords us a higher level of delegated credit autonomy, translating to a significantly shorter turnaround time from application to funding, which is critical to our marketing efforts. We originate loans nationwide under the SBA’s 7(a), SBAExpress, International Trade and 504(a) loan programs, in conformity with SBA underwriting and documentation standards. SBA loans are similar to commercial business loans, but have additional credit enhancement provided by the U.S. Small Business Administration, for up to 85.00% of the loan amount for loans up to $150,000 and 75.00% of the loan amount for loans of more than $150,000. The Company originates SBA loans with the intent to sell the guaranteed portion into the secondary market on a quarterly basis.

• Agribusiness and farmland - We originate loans to the agricultural community to fund seasonal production and longer term investments in land, buildings, equipment, crops and livestock. Agribusiness loans are for the purpose of financing agricultural production to finance crops and livestock. Farmland loans include all land known to be used or usable for agricultural purposes, such as crop and livestock production and is secured by the land and improvements thereon.

• Multi-family - Loans secured by multi-family and commercial real estate properties generally involve a greater degree of credit risk than one-to-four family loans. Because payments on loans secured by multi-family and commercial real estate properties are often dependent on the successful operation or management of the properties, repayment of these loans may be subject to adverse conditions in the real estate market or the economy.

• One-to-four family - Although we do not originate, through our bank acquisitions, we have acquired first lien single family loans, we occasionally purchase such loans to diversify our portfolio. The primary risks of one-to-four family loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make loans unprofitable.

• Construction and land - We originate loans for the construction of one-to-four family and multi-family residences and CRE properties in our market area. We concentrate our efforts on single homes and small infill projects in established neighborhoods where there is not abundant land available for development. Construction loans are considered to have higher risks due to construction completion and timing risk, and the ultimate repayment being sensitive to interest rate changes, government regulation of real property and the availability of long-term financing. Additionally, economic conditions may impact the Company’s ability to recover its investment in construction loans, as adverse economic conditions may negatively impact the real estate market, which could affect the borrower’s ability to complete and sell the project. Additionally, the fair value of the underlying collateral may fluctuate as market conditions change. We occasionally originate land loans located predominantly in California for the purpose of facilitating the ultimate construction of a home or commercial building. The primary risks include the borrower’s inability to pay and the inability of the Company to recover its investment due to a decline in the fair value of the underlying collateral.

• Consumer loans - In addition to consumer loans acquired through our various bank acquisitions, we originate a limited number of consumer loans, generally for banking customers only, which consist primarily of home equity lines of credit, savings account secured loans and auto loans. Repayment of these loans is dependent on the borrower’s ability to pay and the fair value of the underlying collateral.

Various regulatory agencies, as an integral part of their examination process, periodically review the Company’s ALLL and loan review process. Such agencies may require the Company to recognize additions to the allowance based on judgments different from those of management.  

In the opinion of management, and in accordance with the credit loss allowance methodology, the present allowance is considered adequate to absorb probable incurred credit losses as of the date of these consolidated financial statements. Additions and reductions to the allowance are reflected in current operations. Charge-offs recorded against the allowance, for all loan segments, are made when specific loans are considered uncollectible or are transferred to other real estate owned and the fair value of the property is less than the Company’s recorded investment in the loan. Recoveries of amounts previously charged-off are credited to the allowance.

Although management uses the best information available to make these estimates, future adjustments to the allowance may be necessary due to economic, operating, regulatory and other conditions that may extend beyond the Company’s control.

Purchased Credit Impaired Loans. As part of business acquisitions, the Bank acquires certain loans that have shown evidence of credit deterioration since origination, referred to as purchased credit impaired loans. These loans are recorded at the fair value, such that no ALLL for purchase credit impaired (“PCI”) is established upon their acquisition. The Company has elected to account for such loans individually. The Company estimates the amount and timing of expected cash flows for each purchased loan, and the expected cash flows in excess of the fair value is recorded as interest income over the remaining life of the loan and is referred to as the accretable yield. The excess of the loan’s contractual principal and interest over expected cash flows is not recorded and is referred to as the non-accretable difference. Over the life of the loan, expected cash flows continue to be estimated. Subsequent decreases in expected future cash flows beyond the expected cash flows as of the acquisition date are accounted for through a charge to the provision for loan losses. If subsequent reforecasts indicate there has been a probable and significant increase in the level of expected future cash flows, the Company first reduces any previously established ALLL for PCI loans and then accounts for the remainder of the increase through interest income as a yield adjustment.

Other Real Estate Owned. Real estate properties acquired through, or in lieu of, loan foreclosure are recorded at fair value, less cost to sell, with any excess loan balance over the fair value of the property charged against the ALLL. The Company obtains an appraisal and/or market valuation on all other real estate owned at the time of possession. After foreclosure, valuations are periodically performed by management. Any subsequent declines in fair value are recorded as a charge to current period earnings with a corresponding write-down to the asset. All legal fees and direct costs, including foreclosure and other related costs are expensed as incurred.

Premises and Equipment. Premises and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets, which range from forty years for buildings, seven years for furniture, fixtures and equipment, and three years for computer and telecommunication equipment. The cost of leasehold improvements is amortized using the straight-line method over the shorter of the estimated useful life of the asset or the term of the related leases.

The Company periodically evaluates the recoverability of long-lived assets, such as premises and equipment, to ensure the carrying value has not been impaired. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Securities Sold Under Agreements to Repurchase. The Company enters into sales of securities under agreement to repurchase. These agreements are treated as financing arrangements and, accordingly, the obligations to repurchase the securities sold are reflected as liabilities in the Company’s consolidated financial statements. The securities collateralizing these agreements are delivered to several major national brokerage firms who arranged the transactions. The securities are reflected as assets in the Company’s consolidated financial statements. The brokerage firms may loan such securities to other parties in the normal course of their operations and agree to return the identical security to the Company at the maturity of the agreements.

Bank Owned Life Insurance. Bank owned life insurance (“BOLI”) is accounted for using the cash surrender value method and is recorded at its realizable value. Changes in the cash surrender value of BOLI are recorded as a component of noninterest 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 indefinite useful lives 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 typically performs its annual impairment testing in the fourth quarter. 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 recorded in the Company’s consolidated balance sheets.

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 asset is consumed or otherwise used up, or on a straight-line amortization method over their estimated useful lives, which ranges from 6 to 11.5 years.

Loan Commitments and Related Financial Instruments. Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.

Subordinated Debentures. Long-term borrowings are carried at cost, adjusted for amortization of premiums and accretion of discounts, which are recognized in interest expense using the interest method. Debt issuance costs are recognized in interest expense using the interest method over the life of the instrument.

Stock-Based Compensation. The Company issues various forms of stock-based compensation awards annually to officers and directors of the Company, including stock options, restricted stock awards and restricted stock units. The related compensation costs are recognized in the income statement based on the grant-date fair value over the period they are expected to vest, net of estimates for forfeitures. Estimates for forfeitures are based on the Company’s historical experience for each award type. A Black-Scholes model is utilized to estimate the fair value of stock options. The Black-Scholes model uses certain assumptions to determine grant-date fair value such as: expected volatility, expected term of the option, expected risk-free rate of interest and expected dividend yield on the Company’s common stock. The market price of the Company’s common stock at the grant-date is used for restricted stock awards in determining the grant-date fair value for those awards.

Restricted stock units are granted to officers of the Company. Restricted stock units are stock-based compensation awards that when ultimately settled, result in the payment of cash or the issuance of shares of the Company’s common stock to the holder of the award. As with other stock-based compensation awards, compensation cost for restricted stock units is recognized over the period in which the awards are expected to vest. Certain of the Company’s restricted stock units contain vesting conditions which are based on pre-determined performance targets. The level at which the associated performance targets are achieved can impact the ultimate settlement of the award with the grantee and thus the level of compensation expense ultimately recognized. Certain of these awards contain a market condition whereby the vesting of the award is based on the Company’s performance, such as total shareholder return, relative to its peers over a specified period of time. The grant date fair value of market based restricted stock units is determined through the use of an independent third party which employs the use of a Monte Carlo simulation. The Monte Carlo simulation estimates grant date fair value using input assumptions similar to those used in the Black-Scholes model, however, it also incorporates into the grant date fair value calculation the probability that the performance targets will be achieved. The grant date fair value of restricted stock units that do not contain a market condition for vesting is based on the price of the Company’s common stock on the grant date.

Income Taxes. Deferred tax assets and liabilities are recorded for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns using the asset liability method. In estimating future tax consequences, all expected future events other than enactments of changes in the tax law or rates are considered. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are to be recognized for temporary differences that will result in deductible amounts in future years and for tax carryforwards if, in the opinion of management, it is more likely than not that the deferred tax assets will be realized. At December 31, 2018, no valuation allowance was deemed necessary against the Company’s deferred tax assets. At December 31, 2017, a valuation allowance of $380,000 was recorded against the capital loss carryover deferred tax asset, as the Company does not believe it will generate sufficient capital gain before the capital loss carryover expires.

A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and / or penalties related to income tax matters in income tax expense.

Earnings per Share. Earnings per share of common stock is calculated on both a basic and diluted basis based on the weighted average number of common and common equivalent shares outstanding, excluding common shares in treasury. Basic earnings per share excludes potential dilution and is computed by dividing income available to stockholders by the weighted average number of common shares outstanding for the period. 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 then would share in earnings.

Comprehensive Income. Comprehensive income is reported in addition to net income for all periods presented. Comprehensive income is a more inclusive financial reporting methodology that includes disclosure of other comprehensive income (loss) that historically has not been recognized in the calculation of net income. Unrealized gains and losses on the Company’s available-for-sale investment securities are required to be included in other comprehensive income or loss. Total comprehensive income (loss) and the components of accumulated other comprehensive income or loss are presented in the Consolidated Statement of Stockholders’ Equity and Consolidated Statements of Comprehensive Income.

Loss Contingencies. Loss contingencies, including claims and legal action arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the financial statements.

Fair Value of Financial Instruments. Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value is an exit price, representing the amount that would be received to sell an asset or transfer a liability in an orderly transaction between market participants. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Fair value measures are classified according to a three-tier fair value hierarchy, which is based on the observability of inputs used to measure fair value. U.S. GAAP requires the Company to maximize the use of observable inputs when measuring fair value. Changes in assumptions or in market conditions could significantly affect these estimates.

Reclassifications. Some items in prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or stockholders’ equity.

Accounting Standards Adopted in 2018

In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 was signed into law, which among other things reduced the maximum federal corporate tax rate from 35% to 21%. This Update addresses concerns about the guidance in current U.S. GAAP that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date. That guidance is applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income (“AOCI”) were originally recognized in other comprehensive income (rather than in income from continuing operations). As a result of the adjustment of deferred taxes being required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income (referred to as stranded tax effects for purposes of this Update) did not reflect the appropriate tax rate. This Update allows for an election to reclassify between retained earnings and AOCI the impact of the federal income tax rate change. The amendments in this Update are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption of the amendments of this Update is permitted. The Company elected to early adopt in the first quarter of 2018. Accordingly, the Company recorded an increase to AOCI and a decrease to retained earnings of approximately $82,000 for stranded tax effects on available for sale investment securities in the first quarter of 2018.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. Under the current implementation guidance in Topic 805, there are three elements of a business-inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a “set”) that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this Update provide a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this Update (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The amendments provide a framework to assist entities in evaluating whether both an input and a substantive process are present. The framework includes two sets of criteria to consider that depend on whether a set has outputs. Although outputs are not required for a set to be a business, outputs generally are a key element of a business; therefore, the Company has developed more stringent criteria for sets without outputs. Lastly, the amendments in this Update narrow the definition of the term output so that the term is consistent with how outputs are described in Topic 606. Public business entities should apply the amendments in this Update to annual periods beginning after December 15, 2017, including interim periods within those periods. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This Update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In August 2016, the FASB issued ASU 2016-15, Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This Update provides guidance on eight specific cash flow classification issues, which include: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments or debt with coupon interest rates that are insignificant in relation to the effective interest rate; 3) contingent consideration payments made soon after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; 6) distributions received from equity method investments; 7) beneficial interest in securitization transactions; and 8) separately identifiable cash flows and the application of the predominance principle. The amendments in this Update are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period; however, an entity is required to adopt all of the amendments in the same period. The amendments in this Update should be applied using a retrospective transition method to each period presented. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, ASU 2018-04, Investments-Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No.33-9273 (SEC Update), ASU 2018-03, Technical Corrections and Improvements to Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. Changes made to the current measurement model primarily affect the accounting for equity securities with readily determinable fair values, where changes in fair value are included in earnings instead of other comprehensive income. The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged. This Update also changes the presentation and disclosure requirements for financial instruments including a requirement that public business entities use exit price when measuring the fair value of financial instruments measured at amortized cost for disclosure purposes. This Update is effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-01 did not have a material effect on the Company’s operating results or financial condition. In accordance with the guidance, the Company measures the fair value of financial instruments reported at amortized cost on the statement of financial condition using the exit price notion. For further details, refer to footnote Fair Value of Financial Instruments within these consolidated financial statements.

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. With this ASU, 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.

The Company adopted the provisions of ASU 2014-09 and its related amendments effective January 1, 2018 utilizing the modified retrospective transition method and determined the adoption was insignificant to the financial statements. Since the impact upon adoption of ASU 2014-09 and its related amendments was insignificant to the financial statements, a cumulative effect adjustment to retained earnings was not deemed necessary.

The Company’s review of its various revenue streams indicated that approximately 99% of the Company’s revenue is out of the scope of ASU 2014-09 and its related amendments, including all of the Company’s net interest income and a significant portion of non-interest income. For those revenue streams that are within the scope of ASU 2014-09 and its related amendments, the Company reviewed the associated customer contracts and agreements to determine the appropriate accounting for revenues under those contracts. The Company’s review did not identify any significant changes in the timing of revenue recognition under those contracts within the scope of ASU 2014-09 and its related amendments. Significant revenue streams that are within scope primarily relate to service charges and fees associated customer deposit accounts, as well as fees for various other services the Company provides its customers. As a result of the implementation of ASU 2014-09 and its related amendments, the Company conducts a detailed review of its revenue streams at least annually, or more frequently if deemed necessary.

Recent Accounting Guidance Not Yet Effective

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this Update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement.

The following disclosure requirements for public companies were removed from Topic 820:

• The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy.

• The policy for timing of transfers between levels.

• The valuation process for Level 3 fair value measurements.

The following disclosure requirements for public companies were modified in Topic 820:

• The amendments clarify that the measurement of uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date.

The following disclosure requirements for public companies were added to Topic 820:

• The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period

• The range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements

The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. In addition, an entity may early adopt any of the removed or modified disclosures immediately and delay adoption of the new disclosures until the effective date. The Company is currently evaluating the effects of ASU 2018-13 on its financial statements and disclosures.

In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchase Callable Debt Securities. This Update amends guidance on the amortization period of premiums on certain purchased callable debt securities. The amendments shorten the amortization period of premiums on purchased callable debt securities to the earliest call date. This Update should be applied on a modified retrospective basis through a cumulative-effect adjustment to beginning retained earnings. The effective date of ASU 2017-08 is for interim and annual reporting periods beginning after December 15, 2018. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This Update replaces the incurred loss impairment model in current U.S. GAAP with a model that reflects current expected credit losses (“CECL”). The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures. The Update requires that all expected credit losses for financial assets held at the reporting date be measured based on historical experience, current conditions and reasonable and supportable forecasts. The Update also requires enhanced disclosure, including qualitative and quantitative disclosures that provide additional information about significant estimates and judgments used in estimating credit losses. For public business entities, the Update is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures. The Company has formed a working group and a committee made up of members of finance, credit and risk management that are in the process of compiling and analyzing key data elements and implementing a software model that will meet the requirements of the new guidance. The Company has contracted with an industry expert to: (1) develop a new expected loss model with supportable assumptions, (2) identify data, reporting, and disclosure gaps, (3) provide quantitative modeling, and (4) assess, develop and document updates to accounting policies, new processes and controls. The magnitude of the adjustment and the overall impact of the new guidance on the consolidated financial statements cannot yet be reasonably estimated.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), ASU 2018-11, Leases (Topic 842): Targeted Improvements, ASU 2018-10, Codification Improvements to Topic 842, Leases. This Update is being issued to increase the transparency and comparability around lease obligations. Previously unrecorded off-balance sheet obligations will now be recorded in the consolidated financial statements, accompanied by enhanced qualitative and quantitative disclosures in the notes to the consolidated financial statements. The Update is generally effective for public business entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.

In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842): Targeted Improvements.  ASU 2018-10 provides improvements related to ASU 2016-02 to increase stakeholders’ awareness of the amendments to Topic 842 and to expedite the improvements.  The amendments affect narrow aspects of the guidance issued in ASU 2016-02.  ASU 2018-11 allows entities adopting ASU 2016-02 to choose an additional transition method, under which an entity initially applies the accounting guidance for leases under Topic 842 at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, ASU 2018-11 allows an entity electing this additional transition method to continue to present comparative period financial statements in accordance with Topic 840 (current U.S. GAAP).   ASU 2018-11 also allows lessors to not separate non-lease components from the associated lease component if certain conditions are met.  The amendments in these updates become effective for annual periods as well as interim periods within those annual periods beginning after December 15, 2018.

The Company has elected to apply the transition provisions of Topic 842 using the modified retrospective transition method, electing to adopt the “package” of practical expedients in its transition to Topic 842, as specified in ASC 842-10-65. The results of this policy election are that the Company will reflect the provisions of Topic 842 in its consolidated financial statements for the first time as of and for the period ended March 31, 2019 (the period of adoption). The Company will measure and record liabilities to make lease payments as well as right of use assets in the period of adoption for leases that existed as of the transition date, and will continue to present all comparative periods under Topic 840. Under this elected transition method, the Company is not required to reassess the following as part of its Transition to Topic 842: (1) whether any expired or existing contracts contain leases, (2) lease classifications for any existing or expired leases, and (3) initial direct costs for any existing leases. Additionally, the Company has elected to apply the use of hindsight in its assessment of the term for its leases upon transition, which allows for consideration of the Company’s option to extend or terminate a lease.

The Company is currently in the process of finalizing its transition accounting under Topic 842 and anticipates in the first quarter of 2019 it will record a liability to make future lease payments of approximately $43 million and right of use assets of approximately $41 million, the difference being the net of accounting adjustments previously recorded under Topic 840 and Topic 805, as required by transition guidance in ASC 842-10-65. The Company does not currently anticipate a cumulative effect adjustment to the opening balance of retained earnings will be required as part of its transition to Topic 842. The Company’s evaluation of lease obligations and service agreements under the new standard includes an assessment of the appropriate classification and related accounting of each lease agreement, a review of applicability of the new standard to existing service agreements and gathering all essential lease data to facilitate the application of the new standard. The Company’s review indicates that all of its leases are classified as operating leases or short-term leases. In accordance with the provisions of Topic 842, liabilities to make future lease payments and right of use assets will only be recorded for leases that are not considered short-term (leases with an original term of greater than 12 months). The Company will record expense for its leases on a straight-line basis in accordance with the requirements under Topic 842 for operating leases. The Company does not currently believe expense recognition for its operating leases (including short-term leases) under Topic 842 will differ significantly from that recorded under current lease accounting guidance. Right of use assets for operating leases will be amortized over the lease term and liabilities to make future lease payments will be accounted for using the interest method, both in accordance with Topic 842.

Regulatory Capital Requirements and Other Regulatory Matters

Regulatory Capital Requirements and Other Regulatory Matters

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 Bank was categorized as “well capitalized.” There are no conditions or events since that notification that management believes have changed the Bank’s categorization.

Final 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, and fully phased in by January 1, 2019. The most significant of the provisions of the Final Capital Rules, which applied to the Company and the Bank were 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. Under the Basel III rules, the Company must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer increased by 0.625% each year from 0.00% for 2015 to 2.50% in 2019. The capital conservation buffer for 2019 is 2.50% and for 2018 is 1.875%. The net unrealized gain or loss on available-for-sale securities is not included in computing regulatory capital.

As defined in applicable regulations and set forth in the table below, which excludes the capital conservation buffer, at December 31, 2018 and 2017, the Company and the Bank continue to exceed the “well capitalized” standards as well as exceed the Basel III minimum capital ratios of the conservation buffer for each of the risk-based capital ratios:

Unrealized gains and losses on investment securities available-for-sale are recognized in stockholders’ equity as accumulated other comprehensive income or loss. At December 31, 2018, the Company had accumulated other comprehensive loss of $7.9 million, or $5.6 million net of tax, compared to accumulated other comprehensive income of $646,000 or $415,000 net of tax, at December 31, 2017. 

At December 31, 2018, mortgage-backed securities with an estimated par value of $20.3 million and a fair value of $20.9 million were pledged as collateral for the Bank’s HOA reverse repurchase agreements, which totaled $75,000. The average balance of repurchase agreement facilities was $15.0 million during the year ended December 31, 2018.

At December 31, 2018 and 2017, 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, meaning: (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 shall be considered to have occurred. If an OTTI occurs, the cost basis of the security will be written down to its fair value as the new cost basis and the write down accounted for as a realized loss. There were no OTTI as of December 31, 2018 and 2017. As of December 2016, the Company realized OTTI losses net of recoveries of $205,000.

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.

During the years ended December 31, 2018, 2017 and 2016, the Company recognized gross gains on sales of available-for-sale securities in the amounts of $1.6 million, $3.1 million and $1.8 million, respectively. During the years ended December 31, 2018, 2017 and 2016, the Company recognized gross losses on sales of available-for-sale securities in the amounts of $208,000, $386,000 and $9,000, respectively. The Company had net proceeds from the sale or maturity/call of available-for-sale securities of $407.0 million, $268.6 million and $230.9 million during the years ended December 31, 2018, 2017 and 2016, respectively.

FHLB, FRB and other stock

The Company originates SBA loans with the intent to sell the guaranteed portion of the loan prior to maturity and, therefore, designates them as held for sale. From time to time, the Company may purchase or sell other types of loans in order to manage concentrations, maximize interest income, change risk profiles, improve returns and generate liquidity.

Concentration of Credit Risk

The Company’s loan portfolio was collateralized by various forms of real estate and business assets located principally in California, as well as in certain markets in the states of Arizona, Nevada, and Washington where we also have depository offices. The Company’s loan portfolio contains concentrations of credit in commercial non-owner occupied real estate, multi-family real estate and commercial owner occupied business loans. The Company maintains policies approved by the board of directors that address these concentrations and continues to diversify its loan portfolio through loan originations and purchases and sales of loans to meet approved concentration levels. While management believes that the collateral presently securing these loans is adequate, there can be no assurances that significant deterioration in the California real estate market and economy would not expose the Company to significantly greater credit risk.

Loans Serviced for Others

The Company generally retains the servicing rights of the guaranteed portion of SBA loans sold, for which the Company records a servicing asset at fair value and subsequently accounted for at the lower of cost or market value. At December 31, 2018 and 2017, the servicing asset total $8.5 million and $8.8 million, respectively, and was included in other assets. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is recognized through a valuation allowance, to the extent the fair value is less than the carrying amount. At December 31, 2018, and 2017, the Company determined that no valuation allowance was necessary.

Loans serviced for others are not included in the accompanying consolidated statements of financial condition. The unpaid principal balance of loans and participations serviced for others were $635.3 millionDecember 31, 2018 and $634.5 million at December 31, 2017.

Purchased Credit Impaired Loans

The Company has purchased loans through the bank acquisitions, for which there was evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. The carrying amount of those loans at December 31, 2018 and 2017 was as follows:

The Company considers a loan to be impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement or it is determined that the likelihood of the Company receiving all scheduled payments, including interest, when due is remote. The Company has no commitments to lend additional funds to debtors whose loans have been impaired.

The Company reviews loans for impairment when the loan is classified as substandard or worse, delinquent 90 days, determined by management to be collateral dependent, or when the borrower files bankruptcy or is granted a troubled debt restructure. Measurement of impairment is based on the loan’s expected future cash flows discounted at the loan’s effective interest rate, measured by reference to an observable market value, if one exists, or the fair value of the collateral if the loan is deemed collateral dependent. Loans are generally charged-off at the time that 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.

We sometimes modify or restructure loans when the borrower is experiencing financial difficulties by making a concession to the borrower in the form of changes in the amortization terms, reductions in the interest rates, the acceptance of interest only payments and, in limited cases, concessions to the outstanding loan balances. These loans are classified as troubled debt restructurings (“TDRs”) and considered impaired loans. TDRs are loans modified for the purpose of alleviating temporary impairments to the borrower’s financial condition or cash flows. A workout plan between us and the borrower is designed to provide a bridge for borrower cash flow shortfalls in the near term. A TDR loan may be returned to accrual status when the loan is brought current, has performed in accordance with the contractual restructured terms for a time frame of at least six months, and the ultimate collectability of the total contractual restructured principal and interest in no longer in doubt. At December 31, 2018, the Company had no recorded investment in a TDR compared to $97,000 at December 31, 2017.

When loans are placed on nonaccrual status, all accrued interest is reversed from current period 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 six 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 $4.9 million, $3.3 million and $1.1 million at December 31, 2018, 2017 and 2016, respectively. The Company did not record income from the receipt of cash payments related to nonaccruing loans during the years ended December 31, 2018, 2017 and 2016. The Company had $213,000 of loans 90 days or more past due and still accruing at December 31, 2018, all of which were PCI loans. Income recognition for PCI loans is accounted for in accordance with ASC Subtopic 310-30 Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality. The Company had $1.8 million in loans 90 days or more past due and still accruing at December 31, 2017.

Credit Quality and Credit Risk

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 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 and portfolio managers ensure all key risk factors are analyzed with most loan underwriting including a comprehensive global cash flow analysis. 

Credit risk is monitored and 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, P1 - P5 and Watch; along with Special Mention, Substandard, Doubtful and Loss classifications, as such classifications are defined by the federal banking 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 probable incurred 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.

• 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 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 or biannual 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 system as well as certain other information concerning the credit quality of the loan portfolio, including loans held for sale, as of the periods indicated:

Allowance for Loan Losses

Provision for Loan and Lease Losses [Abstract]

Allowance for Loan Losses

Allowance for Loan Losses

The Company’s ALLL covers estimated credit losses on individually evaluated loans that are determined to be impaired as well as estimated probable incurred losses inherent in the remainder of the loan portfolio. The ALLL is prepared using the information provided by the Company’s credit review process together with data from peer institutions and economic information gathered from published sources.

The loan portfolio is segmented into groups of loans with similar risk characteristics. Each segment possesses varying degrees of risk based on, among other things, the type of loan, the type of collateral, and the sensitivity of the borrower or industry to changes in external factors such as economic conditions. An estimated loss rate calculated using the Company’s historical loss rates adjusted for current portfolio trends, economic conditions, and other relevant internal and external factors, is applied to each group’s aggregate loan balances.

The Company’s base ALLL factors are determined by management using the Bank’s annualized actual trailing charge-off data over a full credit cycle with an approximate average loss emergence period of1.4 years. Potential adjustments to those base factors are made for relevant internal and external factors. Those factors may include:

• Changes in lending policies and procedures, including underwriting standards and collection, charge-offs, and recovery practices;

• Changes in the nature and volume of the loan portfolio , as well as new types of lending;

• Changes in the experience, ability, and depth of lending management and other relevant staff that may have an impact on our loan portfolio;

• Changes in the volume and severity of adversely classified or graded loans;

• Changes in the quality of our loan review system and the management oversight;

• The existence and effect of any concentrations of credit and changes in the level of such concentrations;

• Changes in national, regional and local economic conditions, including trends in real estate values and the interest rate environment;

• Changes in the value of the underlying collateral for collateral-dependent loans; and

The effect of external factors, such as competition, legal developments and regulatory requirements on the level of estimated credit losses in our current loan portfolio

For loans risk graded as watch or worse, progressively higher potential loss factors are applied based on migration analysis of risk grading and net charge-offs.

The following tables summarize the allocation of the allowance as well as the activity in the allowance attributed to various segments in the loan portfolio as of and for the periods indicated:

Qualified Affordable Housing Project Investments

The Company’s investment in Qualified Affordable Housing Funds that generate Low Income Housing Tax Credits at December 31, 2018 and 2017 was $39.4 million and $11.6 million, respectively, recorded in other assets. Total unfunded commitments related to the investments in qualified affordable housing funds totaled $13.4 million and $1.3 million at December 31, 2018 and 2017, respectively. The Company has invested in five separate LIHTC funds, which provide the Company with CRA credit. Additionally, the investment in LIHTC funds provide the Company with tax credits and with operating loss tax benefits over an approximately 10 year period. None of the original investment will be repaid. The investments in the WNC Institutional Tax Credit funds are being accounted for using the cost method, under which the Company amortizes as non-interest expense the initial cost of the investment equally over the expected time period in which tax credits and other tax benefits will be received. The investments in the Sycamore Court, R4 CA Housing and Cypress Cove funds qualify for and are being accounted for using the proportional amortization method, which allows for the amortization of the investments to be in proportion to the total of the tax credits and other tax benefits that are allocated to the investor. The tax credits and operating loss tax benefits are recognized in the income statement as a component of income tax expense (benefit) for all LIHTC funds.

The following table presents the Company’s original investment in the LIHTC funds, the current recorded investment balance, and the unfunded liability balance of each investment at December 31, 2018 and 2017. In addition, the table reflects the tax credits and tax benefits recorded by the Company during 2018 and 2017, the amortization of the investment and the net impact to the Company’s income tax provision for 2018 and 2017.

Subordinated Debentures

Subordinated Debentures

In August 2014, the Corporation issued $60.0 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 $50.0 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%, with the first interest payment on the Notes occurring on March 3, 2015, and interest to be paid semiannually each March 3 and September 3 through September 3, 2024. At December 31, 2018, the carrying value of the Notes was $59.3 million, net of unamortized debt issuance costs of $688 thousand. The Notes can only be redeemed, in whole or in part, 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). As of December 31, 2018, the Notes qualify as Tier 2 Capital. Principal and interest are due upon early redemption.

In connection with the Private Placement, the Corporation obtained ratings from Kroll Bond Rating Agency (“KBRA”). KBRA assigned investment grade ratings of BBB+ and BBB for the Corporation’s senior unsecured debt and subordinated debt, respectively, and a deposit rating of A- for the Bank. The Company’s and Bank’s ratings were reaffirmed in October 2018 by KBRA.

In March 2004, the Corporation issued $10.3 million in Floating Rate Junior Subordinated Deferrable Interest Debentures (the “Subordinated Debentures”) to PPBI Trust I, a statutory trust created under the laws of the State of Delaware. The Debt Securities are subordinated to effectively all borrowings of the Corporation and are due and payable on April 6, 2034. Interest is payable quarterly on the Subordinated Debentures at three-month LIBOR plus 2.75% per annum, for an effective rate of 5.19% as of December 31, 2018. The Subordinated Debentures may be redeemed, in part or whole, on or after April 7, 2009 at the option of the Corporation, at par. The Subordinated Debentures can also be redeemed at par if certain events occur that impact the tax treatment or the capital treatment of the issuance. The Corporation also purchased a 3% minority interest totaling $310,000 in PPBI Trust I. The balance of the equity of PPBI Trust I is comprised of mandatorily redeemable preferred securities (“Trust Preferred Securities”) and is included in other assets. PPBI Trust I sold $10.0 million of Trust Preferred Securities to investors in a private offering.

On April 1, 2017, as part of the HEOP acquisition, the Corporation assumed $5.2 million of floating rate junior subordinated debt securities associated with Heritage Oaks Capital Trust II. Interest is payable quarterly at three-month LIBOR plus 1.72% per annum, for an effective rate of 4.12% per annum as of December 31, 2018. At December 31, 2018, the carrying value of these debentures was $4.0 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 December 31, 2018, the carrying value of Mission Community Capital Trust I and Santa Lucia Bancorp (CA) Capital Trust were $2.8 million and $3.8 million, respectively, which reflects purchase accounting fair value adjustments of $306,000 and $1.3 million, respectively. Interest is payable quarterly at three-month LIBOR plus 2.95% per annum, for an effective rate of 5.39% per annum as of December 31, 2018 for Mission Community Capital Trust I. Interest is payable quarterly at three-month LIBOR plus 1.48% per annum, for an effective rate of 3.92% per annum as of December 31, 2018 for Santa Lucia Bancorp (CA) Capital Trust. These three debentures are callable by the Corporation at par.

On November 1, 2017, as part of the PLZZ acquisition, the Company assumed three subordinated notes totaling $25.0 million at a fixed interest rate of 7.125% payable in arrears on a quarterly basis. The notes have a maturity date of June 26, 2025 and are also redeemable in whole, or in part, from time to time beginning in June 26, 2020 at an amount equal to 103.0% of principal plus accrued unpaid interest. The redemption price decreases 50 basis points each subsequent year. At December 31, 2018, the carrying value of these subordinated notes was $25.2 million, which reflects purchase accounting fair value adjustments of $157,000.

On July 1, 2018, as part of the Grandpoint acquisition, the Corporation assumed $5.2 million of floating rate junior subordinated debt securities associated with First Commerce Bancorp Statutory Trust I. Interest is payable quarterly at three-month LIBOR plus 2.95% per annum, for an effective rate of 5.74% per annum as of December 31, 2018. At December 31, 2018, the carrying value of these debentures was $4.9 million, which reflects purchase accounting fair value adjustments of $224,000.

The Corporation is not allowed to consolidate any trust preferred securities into the Company’s consolidated financial statements. The resulting effect on the Company’s consolidated financial statements is to report only the Subordinated Debentures as a component of the Company’s liabilities.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (“Tax Act”). Among other changes, the Tax Act reduces the U.S. federal corporate tax rate from 35% to 21%. The Company performed an initial assessment and reasonably estimated the effects of the Tax Act on its deferred tax amounts to be approximately $5.6 million, which was recorded as a charge to income tax expense in the fourth quarter of 2017, in accordance with SEC Staff Accounting Bulletin No. 118 (“SAB 118”). As required by SAB 118, the Company continued to reassess and refine the effects of the Tax Act on its deferred tax amounts during 2018. As a result, the Company recorded an income tax benefit of $1.4 million during the year ended December 31, 2018. As of December 31, 2018, the Company has completed the accounting for the income tax effects of the Tax Act.

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 forecasts of future income, applicable tax planning strategies, and assessments of current and future economic and business conditions. This analysis is updated quarterly and adjusted as necessary. Based on the analysis, the Company has determined that a valuation allowance for deferred tax assets was not required as of December 31, 2016 and December 31, 2018. As of December 31, 2017, the Company recorded a valuation allowance of $380,000 against the capital loss carryover deferred tax asset, as the Company does not believe it will generate sufficient capital gain before the capital loss carryover expires.

Section 382 of the Internal Revenue Code imposes limitations on a corporation’s ability to use any net unrealized built in losses and other tax attributes, such as net operating loss and tax credit carryforwards, when it undergoes a 50% ownership change over a designated testing period. The Company has a Section 382 limited net operating loss carry forward of approximately $25.7 million for federal income tax purposes, which is scheduled to expire in 2026. In addition, the Company has a Section 382 limited net operating loss carry forward of approximately $8.9 million for California franchise tax purposes, which is scheduled to expire in 2020. The Company is expected to fully utilize the federal and California net operating loss carryforward before it expires with the application of the Section 382 annual limitation.

The Company and its subsidiaries are subject to U.S. Federal income tax as well as income and franchise tax 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 2013. The expiration of the statute of limitations related to the various state income and franchise tax returns varies by state. The Company is currently not under examination in any taxing jurisdiction.

A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2018 and 2017 is as follows:

	2018		2017
	(dollars in thousands)
Balance at January 1,	$	2,906	$	—
Additions based on tax positions related to prior years	—		2,906
Balance at December 31,	$	2,906	$	2,906

The total amount of unrecognized tax benefits was $2.9 million and $2.9 million at December 31, 2018 and 2017, respectively, and is primarily comprised of unrecognized tax benefits from an acquisition during 2017. The total amount of tax benefits that, if recognized, would favorably impact the effective tax rate was $0 at December 31, 2018. The Company does not believe that the unrecognized tax benefits will change within the next twelve months.

The Company recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense. The Company had accrued for $246,000 and $104,000 of the interest and penalties at December 31, 2018 and 2017, respectively.

Commitments, Contingencies and Concentrations of Risk

Lease Commitments – The Company leases a portion of its facilities from non-affiliates under operating leases expiring at various dates through 2028. The following schedule shows the minimum annual lease payments, excluding any renewals and extensions, property taxes, and other operating expenses, due under these agreements:

Year ending December 31,	Amount
	(dollars in thousands)
2019	$	11,468
2020	10,869
2021	10,133
2022	9,296
2023	8,124
Thereafter	10,518
Total	$	60,408

Rental expense under all operating leases totaled $9.2 million for 2018, $4.8 million for 2017, and $4.4 million for 2016.

Legal Proceedings –-The Company is not involved in any material pending legal proceedings other than legal proceedings occurring in the ordinary course of business. Management believes that none of these legal proceedings, individually or in the aggregate, will have a material adverse impact on the results of operations or financial condition of the Company.

Employment Agreements—The Company has entered into a three-year employment agreement with its Chief Executive Officer (“CEO”). This agreement provides for the payment of a base salary, a bonus based upon the CEO’s individual performance and the Company’s overall performance, provides a vehicle for the CEO’s use, and provides for the payment of severance benefits upon termination under specified circumstances.  

Additionally, the Bank has entered into three-year employment agreements with each of the following executive officers: the Bank’s President and Chief Operating Officer, the Chief Credit Officer and Chief Innovation Officer. The agreements provide for the payment of a base salary, a bonus based upon the individual’s performance and the overall performance of the Bank, and the payment of severance benefits upon termination under specified circumstances.

Availability of Funding Sources. The Company funds substantially all of the loans thatit originates or purchases through deposits, internally generated funds and/or borrowings. The Company competes for deposits primarily on the basis of rates, and, as a consequence, the Company could experience difficulties in attracting deposits to fund its operations if the Company does not continue to offer deposit rates at levels that are competitive with other financial institutions. To the extent that the Company is not able to maintain its currently available funding sources or to access new funding sources, it would have to curtail its loan production activities or sell loans and investment securities earlier than is optimal. Any such event could have a material adverse effect on the Company’s results of operations, financial condition and cash flows.

Financial Instruments with Off-Balance Sheet Risk

12 Months Ended

Risks and Uncertainties [Abstract]

Financial Instruments with Off-Balance Sheet Risk

Financial Instruments with Off-Balance Sheet Risk

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit in the form of originating loans or providing funds under existing lines or letters of credit. These commitments are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates and may require payment of a fee. Since many commitments are expected to expire, the total commitment amounts do not necessarily represent future cash requirements. Commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the accompanying consolidated statements of financial condition.

The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual or notional amount of those instruments. The Company controls credit risk of its commitments to fund loans through credit approvals, limits and monitoring procedures. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company evaluates each customer for creditworthiness.

The Company receives collateral to support commitments when deemed necessary. The most significant categories of collateral include real estate properties underlying mortgage loans, liens on personal property and cash on deposit with the Bank.

The Company maintains an allowance for credit losses to provide for commitments related to loans associated with undisbursed loan funds and unused lines of credit. The allowance for these commitments was $4.6 million at December 31, 2018 and $1.9 million at December 31, 2017. The change in the allowance for credit losses for unfunded commitments during the year ended December 31, 2018 was attributable to $2.6 million in fair value adjustments associated unfunded loan commitments and unused lines of credit assumed through the acquisitions of Grandpoint and HEOP. These fair value adjustments were made within the one-year measurement period associated with each acquisition and are attributed to the fair value of unfunded loan commitments and unused lines of credit assumed at the acquisition date.

The Company’s commitments to extend credit at December 31, 2018 were $1.8 billion and $1.2 billion at December 31, 2017. The 2018 balance is primarily composed of $1.1 billion of undisbursed commitments for C&I loans.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The fair value of an asset or liability is the exchange price that would be received to sell that asset or paid to transfer that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach, and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including both those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis and a non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value, 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 December 31, 2018 and December 31, 2017.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management maximizes the use of observable inputs and attempts to minimize the use of unobservable inputs when determining fair value measurements. Estimated fair values are disclosed for financial instruments for which it is practicable to estimate fair value. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates.

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.

Investment securities. Investment securities are generally valued based upon quotes obtained from an independent third-party pricing service, 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.

Impaired Loans and Other Real Estate Owned. A loan is considered impaired when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Impairment is measured based on the fair value of the underlying collateral or the discounted expected future cash flows. The Company measures impairment on all 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 December 31, 2018, substantially all the Company’s impaired loans were evaluated based on the fair value of their underlying collateral based upon the most recent appraisal available to management and has recorded a specific reserve on one loan in the amount of $584,000 with a principal balance of $1.0 million.

The fair value of impaired loans and other real estate owned were determined using Level 3 assumptions, and represents impaired loan and other real estate owned balances for which a specific reserve has been established or on which a write down has been taken. Generally, the Company obtains third party appraisals (or property valuations) and/or collateral audits in conjunction with internal analysis based on historical experience on its impaired loans and other real estate owned to determine fair value. In determining the net realizable value of the underlying collateral for impaired loans, the Company will then discount the valuation to cover both market price fluctuations and selling costs the Company expected would be incurred in the event of foreclosure. In addition to the discounts taken, the Company’s calculation of net realizable value considered any other senior liens in place on the underlying collateral.

The fair value estimates presented herein are based on pertinent information available to management as of the dates indicated, representing an exit price.

(1) The estimated fair value of loans held for investment, net for December 31, 2017 is not based on an exit price assumption.

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 non-recurring Level 3 when the fair value of the underlying collateral is based on an observable market price or current appraised value. When current market prices are not available or the Company determines that the fair value of the underlying collateral is further impaired below appraised values, the Company records impaired loans as Level 3. At December 31, 2018, substantially all the Company’s impaired loans were evaluated based on the fair value of their underlying collateral based upon the most recent appraisal available to management.

The measures of fair value on a non-recurring basis are immaterial at December 31, 2018 and 2017. The following fair value hierarchy tables present information about the Company’s assets measured at fair value on a recurring basis at the dates 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.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Earnings per share of common stock is calculated on both a basic and diluted basis based on the weighted average number of common and common equivalent shares outstanding, excluding common shares in treasury. Basic earnings per share excludes potential dilution and is computed by dividing income available to stockholders by the weighted average number of common shares outstanding for the period. The Company has no outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends that would be considered participating securities for the basic calculation. 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 then would 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. There are no anti-dilutive stock options at December 31, 2018. The weighted average number of stock options excluded was for 17,524 for December 31, 2017 and 82,760 for December 31, 2016.

A reconciliation of the numerators and denominators used in basic and diluted earnings per share computations is presented in the table below.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

Derivative Instruments

From time to time, the Company enters into interest rate swap agreements with certain borrowers to assist them in mitigating their interest rate risk exposure associated with the loans they have with the Company. At the same time, the Company enters into identical interest rate swap agreements with another financial institution to mitigate the Company’s interest rate risk exposure associated with the swap agreements it enters into with its borrowers. At December 31, 2018, the Company had swaps with matched terms with an aggregate notional amount of $57.5 million and a fair value of $1.7 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 and net to zero 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 twelve months ended December 31, 2018, there were no losses recorded on swap agreements, attributable to the change in credit risk associated with a counterparty. All interest rate swap agreements entered into by the Company as of December 31, 2018 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 2017 HEOP acquisition, and the Company did not have any at December 31, 2016:

Balance Sheet Offsetting

Balance Sheet Offsetting

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

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Revenue Recognition

The Company earns revenue from a variety of sources. The Company’s principal source of revenue is interest income on loans, investment securities and other interest earning assets, while the remainder of the Company’s revenue is earned from a variety of fees, service charges, gains and losses, and other income, all of which are classified as noninterest income. Revenue from interest on loans and investment securities is accounted for on an accrual basis using the interest method, while revenue from other sources is accounted for under other applicable U.S. GAAP as well as ASC 606 - Revenue from Contracts with Customers. Revenue streams within the scope of and accounted for under ASC 606 include: service charges and fees on deposit accounts, debit card interchange fees, fees from other services the Company provides its customers and gains and losses from the sale of other real estate owned and property, premises and equipment. ASC 606 requires revenue to be recognized when the Company satisfies the related performance obligations by transferring to the customer a good or service. The recognition of revenue under ASC 606 requires the Company to first identify the contract with the customer, identify the associated performance obligations, determine the transaction price, allocate the transaction price to the performance obligations and finally recognize revenue when the performance obligations have been satisfied and the good or service has been transferred. The majority of the Company’s contracts with customers associated with revenue streams that are within the scope of ASC 606 are considered short-term in nature and can be canceled at any time by the customer or the Company without penalty, such as a deposit account agreement. These revenue streams are included in non-interest income.

The following table provides a summary of the Company’s revenue streams, including those that are within the scope of ASC 606 and those that are accounted for under other applicable U.S. GAAP:

______________________________

⁽¹⁾ Revenues from contracts with customers accounted for under ASC 606.

⁽²⁾ Revenues not within the scope of ASC 606 and accounted for under other applicable U.S. GAAP requirements.

The following provides information concerning the major components of the Company’s revenue:

Interest Income. Interest income is comprised of interest on loans, investment securities and other interest-earning assets. Interest is recognized using the interest method, which reflects the contractual yield on loans and coupon yield for investment securities. These yields are adjusted for purchase discounts, premiums and net deferred loan origination fees for newly originated loans.

Loan Servicing Fees. Loan servicing fees generally consist of fees related to servicing of loans for others, as well as the net impact of related serving asset amortization. ASC 606 stipulates that income streams generated through the transfer and servicing of financial instruments shall be accounted for under ASC 860 - Transfers and Servicing and is therefore excluded from the scope of ASC 606.

Service Charges on Deposit Accounts and Other Service Fee Income. Service charges on deposit accounts and other service fee income consists of periodic service charges on deposit accounts and transaction based fees such as those related to overdrafts, ATM charges and wire transfer fees. The majority of these revenues are accounted for under ASC 606. Performance obligations for periodic service charges on deposit accounts are typically short-term in nature and are generally satisfied on a monthly basis, while performance obligations for other transaction based fees are typically satisfied at a point in time (which may consist of only a few moments to perform the service or transaction) with no further obligations on behalf of the Company to the customer. Periodic service charges are generally collected monthly directly from the customer’s deposit account, and at the end of a statement cycle, while transaction based service charges are typically collected at the time of or soon after the service is performed.

Debit Card Interchange Income. Debit card interchange fee income consists of transaction processing fees associated with customer debit card transactions processed through a payment network and are accounted for under ASC 606. These fees are earned each time a request for payment is originated by a customer debit cardholder at a merchant. In these transactions, the Company transfers funds from the debit cardholder’s account to a merchant through a payment network at the request of the debit cardholder by way of the debit card transaction. The related performance obligations are generally satisfied when the transfer of funds is complete, which is generally a point in time when the debit card transaction is processed. Debit card interchange fees are typically received and recorded as revenue on a daily basis.

Earnings on Bank Owned Life Insurance. Earnings on BOLI relate to the periodic increase in the cash surrender value of BOLI policies on certain key employees of the Company for which the Company is the owner and beneficiary of the related policies. This revenue stream is excluded from the scope of ASC 606, and is accounted for under other applicable U.S. GAAP provisions (ASC 325-30).

Gains and (Losses) from Sales of Loans and Investment Securities. ASC 606 stipulates that gains and (losses) from the periodic sale of loans and investment securities are excluded from ASC 606 and are accounted for under other applicable U.S. GAAP provisions.

Other Income. Other income generally consists of recoveries on acquired loans, which were fully charged off and had no book value prior to their acquisition, as well as other miscellaneous loan fees, and rental income from various subleases. These revenue streams are excluded from the scope of ASC 606 and are accounted for under other applicable U.S. GAAP provisions. Other income also consists of other miscellaneous fees, which are accounted for under ASC 606; however, much like service charges on deposit accounts, these fees have performance obligations that are very short-term in nature and are typically satisfied at a point in time. Revenue is typically recorded at the time these fees are collected, which is generally upon the completion the related transaction or service provided.

Other revenue streams that may be applicable to the Company include gains and losses from the sale of non-financial assets such as other real estate owned and property premises and equipment. The Company accounts for these revenue streams in accordance with ASC 610-20, which requires the Company to look to guidance in ASC 606 in the application of certain measurement and recognition concepts. The Company records gains and losses on the sale of non-financial assets when control of the asset has been surrendered to the buyer, which generally occurs at a specific point in time.

Practical Expedient. The Company also employs a practical expedient with respect to contract acquisition costs, which are generally capitalized and amortized into expense. These costs relate to expenses incurred directly attributable to the efforts to obtain a contract. The practical expedient allows the Company to immediately recognize contract acquisition costs in current period earnings when these costs would have been amortized over a period of one year or less.

At December 31, 2018 the Company did not have any material contract assets or liabilities in its consolidated financial statements related to revenue streams within the scope of ASC 606, and there were no material changes in those balances during the reporting period.

Consideration paid							120,174
Goodwill recognized							$	51,658

The Company accounted for these transactions under the acquisition method of accounting in accordance with ASC 805, Business Combinations, which requires purchased assets and liabilities assumed to be recorded at their respective fair values at the date of acquisition.

The loan portfolios of Grandpoint, PLZZ, HEOP and SCAF were recorded at fair value at the date of each acquisition. The valuation of loan portfolios of Grandpoint, PLZZ, HEOP and SCAF’s were performed as of the acquisition dates to assess their fair values. The loan portfolios were split into two groups: loan with credit deterioration and loans without credit deterioration, and then segmented further by loan type. The fair value was calculated on an individual loan basis using a discounted cash flow analysis. The discount rate utilized was based on a weighted average cost of capital, considering the cost of equity and cost of debt. Also factored into the fair value estimates were loss rates, recovery period and prepayment rates based on industry standards.

For loans acquired from Grandpoint, PLZZ, HEOP and SCAF, the contractual amounts due, expected cash flows to be collected, interest component and fair value as of the respective acquisition dates were as follows:

	Acquired Loans
	Grandpoint		PLZZ		HEOP		SCAF
	(dollars in thousands)
Contractual amounts due	$	3,496,905	$	1,708,685	$	1,717,230	$	539,806
Cash flows not expected to be collected	39,071		20,152		4,442		2,765
Expected cash flows	3,457,834		1,688,533		1,712,788		537,041
Interest component of expected cash flows	1,105,117		625,632		348,100		80,883
Fair value of acquired loans	$	2,352,717	$	1,062,901	$	1,364,688	$	456,158

In accordance with generally accepted accounting principles, there was no carryover of the allowance for loan losses that had been previously recorded by Grandpoint, PLZZ, HEOP and SCAF.

The Company also determined the fair value of the core deposit intangible, securities and deposits with the assistance of third-party valuations and determined the fair value of OREO from recent appraisals of the properties less estimated costs to sell. Since the fair value of intangible assets is calculated as if they were stand-alone assets, the presumption is that a hypothetical buyer of the intangible asset would be able to take advantage of potential after tax benefits resulting from the asset purchase.

The core deposit intangible on non-maturing deposit represents future benefits arising from savings on source of funding and was determined by evaluating the underlying characteristics of the deposit relationships, including customer attrition, deposit interest rates, service charge income, overhead expense and costs of alternative funding. The value of the after tax savings on cost of fund is the present value over a estimated fifty-year horizon, using the discount rate applicable to the asset.

In determining the fair value of certificates of deposit, a discounted cash flow analysis was used, which involved present valuing the contractual payments over the remaining life of the certificates of deposit at market-based interest rates

Accounting Policies [Abstract]

Description of Business

Description of Business—Pacific Premier Bancorp, Inc., a Delaware corporation organized in 1997 (the “Corporation”), is a California-based bank holding company that owns 100% of the capital stock of Pacific Premier Bank, a California-chartered commercial bank (the “Bank,” and together with the Corporation and its consolidated subsidiaries, the “Company”), the Corporation’s principal operating subsidiary. The Bank was incorporated and commenced operations in 1983.

The principal business of the Company is attracting deposits from the general public and investing those deposits, together with funds generated from operations and borrowings, primarily in business loans and real estate property loans. At December 31, 2018, the Company had 44 depository branches located in the counties of Orange, Los Angeles, Riverside, San Bernardino, San Diego, San Luis Obispo and Santa Barbara, California, as well as Pima and Maricopa Counties, Arizona, Clark County, Nevada and Clark County, Washington. The Company is subject to competition from other financial institutions. The Company is subject to the regulations of certain governmental agencies and undergoes periodic examinations by those regulatory authorities.

Principles of Consolidation

Principles of Consolidation—The consolidated financial statements include the accounts of Corporation and its wholly-owned subsidiary the Bank. The Company accounts for its investments in its wholly-owned special purpose entities, PPBI Statutory Trust I, Heritage Oaks Capital Trust II, Mission Community Capital Trust I Santa Lucia Bancorp (CA) Capital Trust and First Commerce Bancorp Statutory Trust I, under the equity method whereby the subsidiary’s net earnings are recognized in the Company’s Statement of Income and the investment in these entities is included in Other Assets on the Company’s Consolidated Statements of Financial Condition. The Company is organized and operates as a single reporting segment, principally engaged in the commercial banking business. All significant intercompany accounts and transactions have been eliminated in consolidation.

Basis of Financial Statement Presentation

Basis of Financial Statement Presentation—The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (‘‘U.S. GAAP’’). Certain amounts in the financial statements and related footnote disclosures for the prior years have been reclassified to conform to the current presentation with no impact to previously reported net income or stockholders’ equity.

Use of Estimates

Use of Estimates—The preparation of consolidated financial statements in conformity with U.S. GAAP 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, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates may change as new information is obtained.

Cash and Cash Equivalents

Cash and Cash Equivalents—Cash and cash equivalents include cash on hand, cash balances due from banks and federal funds sold. Interest bearing deposits with financial institutions represent primarily cash held at the Federal Reserve Bank of San Francisco. At December 31, 2018, there were no cash reserves required by the Board of Governors of the Federal Reserve System (“Federal Reserve”) for depository institutions based on the amount of deposits held. The Company maintains amounts due from banks that exceed federally insured limits. The Company has not experienced any losses in such accounts.

Securities

Securities—The Company has established written guidelines and objectives for its investing activities. At the time of purchase, management designates the security as either held to maturity, available-for-sale or held for trading based on the Company’s investment objectives, operational needs and intent. The investments are monitored to ensure that those activities are consistent with the established guidelines and objectives.

Securities Held-to-Maturity/Available-for-sale

Securities Available-for-Sale—Investments in debt securities that management has no immediate plan to sell, but which may be sold in the future, are carried at fair value. Premiums and discounts are amortized using the interest method over the remaining period to the call date for premiums or contractual maturity for discounts and, in the case of mortgage-backed securities, the estimated average life, which can fluctuate based on the anticipated prepayments on the underlying collateral of the securities. Unrealized holding gains and losses, net of tax, are recorded in a separate component of stockholders’ equity as accumulated other comprehensive income. Realized gains and losses on the sales of securities are determined on the specific identification method, recorded on a trade date basis based on the amortized cost basis of the specific security and are included in noninterest income as net gain (loss) on investment securities.

Securities Held-to-Maturity—Investments in debt securities that management has the positive intent and ability to hold to maturity are reported at cost and adjusted for periodic principal payments and the amortization of premiums and accretion of discounts, which are recognized in interest income using the interest method over the period of time to investment’s maturity.

Impairment of Investments

Impairment of Investments—Quarterly, the Company evaluates investment securities in an unrealized loss position for OTTI. In determining whether a security’s decline in fair value is other-than-temporary, the Company considers a number of factors including: (i) the length of time and the extent to which the fair value of the investment has been less than its amortized cost; (ii) the financial condition and near-term prospects of the issuer; (iii) the intent and ability of the Company to hold the investment for a period of time sufficient to allow for an anticipated recovery in fair value; (iv) downgrades in credit ratings; and (v) general market conditions which reflect prospects for the economy as a whole, including interest rates and sector credit spreads. If it is determined that an OTTI exists, and either the Company intends to sell the investment or it is likely the Company will be required to sell the investment before its anticipated recovery, the total amount of the OTTI, which is measured as the amount by which the investment’s amortized cost exceeds its fair value, is recognized in current period earnings. If the Company has the intent and ability to hold the investment and it is more likely than not it will be required to sell the investment prior to an anticipated recovery of its amortized cost basis, the Company records in current period earnings the portion of OTTI deemed to be credit related, while the remaining portion of OTTI deemed to be non-credit related is recorded in accumulated other comprehensive income. Credit related losses are determined through a discounted cash flow analysis, which incorporates assumptions concerning the estimated timing and amounts of expected cash flows. Non-credit related OTTI losses result from other factors such as change in interest rates and general market conditions. The presentation of OTTI in the consolidated financial statements is on a gross basis with a reduction in the gross amount for the portion of the loss deemed non-credit related and is recorded in accumulated other comprehensive income.

Federal Home Loan Bank Stock

Federal Home Loan Bank Stock—The Bank is a member of the Federal Home Loan Bank System. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are recorded as a component of interest income.

Federal Reserve Bank Stock

Federal Reserve Bank Stock—The Bank is a member of the Federal Reserve Bank of San Francisco (the “FRB”). FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are recorded as a component of interest income.

Loans Held for Sale

Loans Held for Sale—Loans that the Company has the intent to sell prior to maturity have been designated as held for sale at origination and are recorded at lower of cost or fair value. Gains or losses are recognized upon the sale of the loans on a specific identification basis.

Loan Servicing Assets

Loan Servicing Assets—Servicing assets are related to SBA loans sold and are recognized at the time of sale when servicing is retained with the income statement effect recorded in gains on sales of SBA loans. Servicing assets are initially recorded at fair value based on the present value of the contractually specified servicing fee, net of estimated servicing costs, over the estimated life of the loan, using a discount rate. The Company’s servicing costs approximates the industry average servicing costs of approximately 40 basis points. The servicing assets are subsequently amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. The Company periodically evaluates servicing assets for impairment based upon the fair value of the assets as compared to their carrying amount.

The Company typically sells the guaranteed portion of SBA loans and retains the unguaranteed portion (“retained interest”). A portion of the premium on sale of SBA loans is recognized as gain on sale of loans at the time of the sale by allocating the carrying amount between the asset sold and the retained interest, based on their relative fair values. The remaining portion of the premium is recorded as a discount on the retained interest and is amortized over the remaining life of the loan as an adjustment to yield. The retained interest, net of any discount, are included in loans held for investment—net of allowance for loan losses in the accompanying consolidated statements of financial condition.

Loans Held for Investment

Loans Held for Investment—Loans held for investment are loans the Company has the ability and intent to hold until their maturity. The loans are carried at amortized cost, net of discounts and premiums on purchased loans, deferred loan origination fees and costs and ALLL. Net deferred loan origination fees and costs on loans are amortized or accreted using the interest method over the expected life of the loans. Amortization of deferred loan fees and costs are discontinued for loans placed on nonaccrual. Any remaining deferred fees or costs and prepayment fees associated with loans that payoff prior to contractual maturity are included in loan interest income in the period of payoff. Loan commitment fees received to originate or purchase a loan are deferred and, if the commitment is exercised, recognized over the life of the loan using the interest method as an adjustment of yield or, if the commitment expires unexercised, recognized as income upon expiration of the commitment.

Interest on loans is recognized using the interest method and is only accrued if deemed collectible. Loans for which the accrual of interest has been discontinued are designated as nonaccrual loans. The accrual of interest on loans is discontinued when principal or interest is past due 90 days based on contractual terms of the loan or when, in the opinion of management, there is reasonable doubt as to collection of principal and or interest. When loans are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Interest income generally is not recognized on nonaccrual loans unless the likelihood of further loss is remote. Interest payments received on nonaccrual loans are applied as a reduction to the loan principal balance. Interest accruals are resumed on such loans only when they are brought current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to all principal and interest.

A loan is considered to be impaired when it is probable that the Company will be unable to collect all amounts due (principal and interest) according to the contractual terms of the loan agreement. The Company reviews loans for impairment when the loan is classified as substandard or worse, delinquent 90 days, determined by management to be collateral dependent, or when the borrower files bankruptcy or is granted concession which qualifies as a troubled debt restructuring. 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. The Company selects the measurement method on a loan-by-loan basis except those loans deemed collateral dependent. Loans for which impairment has been determined are generally charged-off at such time the loan is classified as a loss.

Allowance for Loan Losses

Allowance for Loan Losses—The Company maintains an ALLL at a level deemed appropriate by management to provide for known or probable incurred losses in the portfolio as of the date of the consolidated statements of financial condition. The Company has an internal loan review system and loss allowance methodology designed to provide for the detection of problem loans and an appropriate level of allowance to cover loan losses. Management’s determination of the adequacy of the ALLL is based on an evaluation of the composition of the portfolio, actual loss experience, industry charge-off experience on income property loans, current economic conditions, and other relevant factors in the area in which the Company’s lending and real estate activities are based. These factors may affect the borrower’s ability to pay as well as the value of the underlying collateral securing loans. The allowance is calculated by applying loss factors to loans held for investment according to loan type and loan credit classification. The loss factors are based primarily upon the Bank’s historical loss experience and industry charge-off experience, and are evaluated on a quarterly basis.

At December 31, 2018, the following portfolio segments have been identified. Segments are groupings of similar loans at a level, for which the Company has adopted systematic methods of documentation for determining its allowance for loan losses:

• Commercial and industrial (including Franchise) - Commercial and industrial (“C&I”) loans are secured by business assets including inventory, receivables and machinery and equipment to businesses located generally in our primary market area. Loan types includes revolving lines or credit, term loans, seasonal loans and loans secured by liquid collateral such as cash deposits or marketable securities. Homeowners’ Association (“HOA”) credit facilities are included in C&I loans. We also issue letters of credit on behalf of our customers. Risk arises primarily due to the difference between expected and actual cash flows of the borrowers. In addition, the recoverability of the Company’s investment in these loans is also dependent on other factors primarily dictated by the type of collateral securing these loans. The fair value of the collateral securing these loans may fluctuate as market conditions change. In the case of loans secured by accounts receivable, the recovery of the Company’s investment is dependent upon the borrower’s ability to collect amounts due from its customers.

• Commercial real estate (including owner-occupied and nonowner occupied) - Commercial real estate (“CRE”) includes various type of loans which the Company holds real property as collateral. CRE lending activity is typically restricted to owner-occupied or nonowner-occupied. The primary risks of real estate loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make the real estate loan unprofitable to the borrower. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy.

• SBA - We are approved to originate loans under the SBA’s Preferred Lenders Program (“PLP”). The PLP lending status affords us a higher level of delegated credit autonomy, translating to a significantly shorter turnaround time from application to funding, which is critical to our marketing efforts. We originate loans nationwide under the SBA’s 7(a), SBAExpress, International Trade and 504(a) loan programs, in conformity with SBA underwriting and documentation standards. SBA loans are similar to commercial business loans, but have additional credit enhancement provided by the U.S. Small Business Administration, for up to 85.00% of the loan amount for loans up to $150,000 and 75.00% of the loan amount for loans of more than $150,000. The Company originates SBA loans with the intent to sell the guaranteed portion into the secondary market on a quarterly basis.

• Agribusiness and farmland - We originate loans to the agricultural community to fund seasonal production and longer term investments in land, buildings, equipment, crops and livestock. Agribusiness loans are for the purpose of financing agricultural production to finance crops and livestock. Farmland loans include all land known to be used or usable for agricultural purposes, such as crop and livestock production and is secured by the land and improvements thereon.

• Multi-family - Loans secured by multi-family and commercial real estate properties generally involve a greater degree of credit risk than one-to-four family loans. Because payments on loans secured by multi-family and commercial real estate properties are often dependent on the successful operation or management of the properties, repayment of these loans may be subject to adverse conditions in the real estate market or the economy.

• One-to-four family - Although we do not originate, through our bank acquisitions, we have acquired first lien single family loans, we occasionally purchase such loans to diversify our portfolio. The primary risks of one-to-four family loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make loans unprofitable.

• Construction and land - We originate loans for the construction of one-to-four family and multi-family residences and CRE properties in our market area. We concentrate our efforts on single homes and small infill projects in established neighborhoods where there is not abundant land available for development. Construction loans are considered to have higher risks due to construction completion and timing risk, and the ultimate repayment being sensitive to interest rate changes, government regulation of real property and the availability of long-term financing. Additionally, economic conditions may impact the Company’s ability to recover its investment in construction loans, as adverse economic conditions may negatively impact the real estate market, which could affect the borrower’s ability to complete and sell the project. Additionally, the fair value of the underlying collateral may fluctuate as market conditions change. We occasionally originate land loans located predominantly in California for the purpose of facilitating the ultimate construction of a home or commercial building. The primary risks include the borrower’s inability to pay and the inability of the Company to recover its investment due to a decline in the fair value of the underlying collateral.

• Consumer loans - In addition to consumer loans acquired through our various bank acquisitions, we originate a limited number of consumer loans, generally for banking customers only, which consist primarily of home equity lines of credit, savings account secured loans and auto loans. Repayment of these loans is dependent on the borrower’s ability to pay and the fair value of the underlying collateral.

Various regulatory agencies, as an integral part of their examination process, periodically review the Company’s ALLL and loan review process. Such agencies may require the Company to recognize additions to the allowance based on judgments different from those of management.  

In the opinion of management, and in accordance with the credit loss allowance methodology, the present allowance is considered adequate to absorb probable incurred credit losses as of the date of these consolidated financial statements. Additions and reductions to the allowance are reflected in current operations. Charge-offs recorded against the allowance, for all loan segments, are made when specific loans are considered uncollectible or are transferred to other real estate owned and the fair value of the property is less than the Company’s recorded investment in the loan. Recoveries of amounts previously charged-off are credited to the allowance.

Although management uses the best information available to make these estimates, future adjustments to the allowance may be necessary due to economic, operating, regulatory and other conditions that may extend beyond the Company’s control.

Purchased Credit Impaired Loans

Purchased Credit Impaired Loans. As part of business acquisitions, the Bank acquires certain loans that have shown evidence of credit deterioration since origination, referred to as purchased credit impaired loans. These loans are recorded at the fair value, such that no ALLL for purchase credit impaired (“PCI”) is established upon their acquisition. The Company has elected to account for such loans individually. The Company estimates the amount and timing of expected cash flows for each purchased loan, and the expected cash flows in excess of the fair value is recorded as interest income over the remaining life of the loan and is referred to as the accretable yield. The excess of the loan’s contractual principal and interest over expected cash flows is not recorded and is referred to as the non-accretable difference. Over the life of the loan, expected cash flows continue to be estimated. Subsequent decreases in expected future cash flows beyond the expected cash flows as of the acquisition date are accounted for through a charge to the provision for loan losses. If subsequent reforecasts indicate there has been a probable and significant increase in the level of expected future cash flows, the Company first reduces any previously established ALLL for PCI loans and then accounts for the remainder of the increase through interest income as a yield adjustment.

Other Real Estate Owned

Other Real Estate Owned. Real estate properties acquired through, or in lieu of, loan foreclosure are recorded at fair value, less cost to sell, with any excess loan balance over the fair value of the property charged against the ALLL. The Company obtains an appraisal and/or market valuation on all other real estate owned at the time of possession. After foreclosure, valuations are periodically performed by management. Any subsequent declines in fair value are recorded as a charge to current period earnings with a corresponding write-down to the asset. All legal fees and direct costs, including foreclosure and other related costs are expensed as incurred.

Premises and Equipment

Premises and Equipment. Premises and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets, which range from forty years for buildings, seven years for furniture, fixtures and equipment, and three years for computer and telecommunication equipment. The cost of leasehold improvements is amortized using the straight-line method over the shorter of the estimated useful life of the asset or the term of the related leases.

The Company periodically evaluates the recoverability of long-lived assets, such as premises and equipment, to ensure the carrying value has not been impaired. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Securities Sold Under Agreements to Repurchase

Securities Sold Under Agreements to Repurchase. The Company enters into sales of securities under agreement to repurchase. These agreements are treated as financing arrangements and, accordingly, the obligations to repurchase the securities sold are reflected as liabilities in the Company’s consolidated financial statements. The securities collateralizing these agreements are delivered to several major national brokerage firms who arranged the transactions. The securities are reflected as assets in the Company’s consolidated financial statements. The brokerage firms may loan such securities to other parties in the normal course of their operations and agree to return the identical security to the Company at the maturity of the agreements.

Bank Owned Life Insurance

Bank Owned Life Insurance. Bank owned life insurance (“BOLI”) is accounted for using the cash surrender value method and is recorded at its realizable value. Changes in the cash surrender value of BOLI are recorded as a component of noninterest 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 indefinite useful lives 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 typically performs its annual impairment testing in the fourth quarter. 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 recorded in the Company’s consolidated balance sheets.

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 asset is consumed or otherwise used up, or on a straight-line amortization method over their estimated useful lives, which ranges from 6 to 11.5 years.

Loan Commitments and Related Financial Instruments

Loan Commitments and Related Financial Instruments. Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.

Subordinated Debentures

Subordinated Debentures. Long-term borrowings are carried at cost, adjusted for amortization of premiums and accretion of discounts, which are recognized in interest expense using the interest method. Debt issuance costs are recognized in interest expense using the interest method over the life of the instrument.

Stock-Based Compensation

Stock-Based Compensation. The Company issues various forms of stock-based compensation awards annually to officers and directors of the Company, including stock options, restricted stock awards and restricted stock units. The related compensation costs are recognized in the income statement based on the grant-date fair value over the period they are expected to vest, net of estimates for forfeitures. Estimates for forfeitures are based on the Company’s historical experience for each award type. A Black-Scholes model is utilized to estimate the fair value of stock options. The Black-Scholes model uses certain assumptions to determine grant-date fair value such as: expected volatility, expected term of the option, expected risk-free rate of interest and expected dividend yield on the Company’s common stock. The market price of the Company’s common stock at the grant-date is used for restricted stock awards in determining the grant-date fair value for those awards.

Restricted stock units are granted to officers of the Company. Restricted stock units are stock-based compensation awards that when ultimately settled, result in the payment of cash or the issuance of shares of the Company’s common stock to the holder of the award. As with other stock-based compensation awards, compensation cost for restricted stock units is recognized over the period in which the awards are expected to vest. Certain of the Company’s restricted stock units contain vesting conditions which are based on pre-determined performance targets. The level at which the associated performance targets are achieved can impact the ultimate settlement of the award with the grantee and thus the level of compensation expense ultimately recognized. Certain of these awards contain a market condition whereby the vesting of the award is based on the Company’s performance, such as total shareholder return, relative to its peers over a specified period of time. The grant date fair value of market based restricted stock units is determined through the use of an independent third party which employs the use of a Monte Carlo simulation. The Monte Carlo simulation estimates grant date fair value using input assumptions similar to those used in the Black-Scholes model, however, it also incorporates into the grant date fair value calculation the probability that the performance targets will be achieved. The grant date fair value of restricted stock units that do not contain a market condition for vesting is based on the price of the Company’s common stock on the grant date.

Income Taxes

Income Taxes. Deferred tax assets and liabilities are recorded for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns using the asset liability method. In estimating future tax consequences, all expected future events other than enactments of changes in the tax law or rates are considered. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are to be recognized for temporary differences that will result in deductible amounts in future years and for tax carryforwards if, in the opinion of management, it is more likely than not that the deferred tax assets will be realized. At December 31, 2018, no valuation allowance was deemed necessary against the Company’s deferred tax assets. At December 31, 2017, a valuation allowance of $380,000 was recorded against the capital loss carryover deferred tax asset, as the Company does not believe it will generate sufficient capital gain before the capital loss carryover expires.

A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and / or penalties related to income tax matters in income tax expense.

Earnings per Share

Earnings per Share. Earnings per share of common stock is calculated on both a basic and diluted basis based on the weighted average number of common and common equivalent shares outstanding, excluding common shares in treasury. Basic earnings per share excludes potential dilution and is computed by dividing income available to stockholders by the weighted average number of common shares outstanding for the period. 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 then would share in earnings.

Comprehensive Income

Comprehensive Income. Comprehensive income is reported in addition to net income for all periods presented. Comprehensive income is a more inclusive financial reporting methodology that includes disclosure of other comprehensive income (loss) that historically has not been recognized in the calculation of net income. Unrealized gains and losses on the Company’s available-for-sale investment securities are required to be included in other comprehensive income or loss. Total comprehensive income (loss) and the components of accumulated other comprehensive income or loss are presented in the Consolidated Statement of Stockholders’ Equity and Consolidated Statements of Comprehensive Income.

Loss Contingencies

Loss Contingencies. Loss contingencies, including claims and legal action arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the financial statements.

Fair Value of Financial Instruments

Fair Value of Financial Instruments. Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value is an exit price, representing the amount that would be received to sell an asset or transfer a liability in an orderly transaction between market participants. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Fair value measures are classified according to a three-tier fair value hierarchy, which is based on the observability of inputs used to measure fair value. U.S. GAAP requires the Company to maximize the use of observable inputs when measuring fair value. Changes in assumptions or in market conditions could significantly affect these estimates.

The fair value of an asset or liability is the exchange price that would be received to sell that asset or paid to transfer that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach, and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including both those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis and a non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value, 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 December 31, 2018 and December 31, 2017.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management maximizes the use of observable inputs and attempts to minimize the use of unobservable inputs when determining fair value measurements. Estimated fair values are disclosed for financial instruments for which it is practicable to estimate fair value. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates.

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.

Investment securities. Investment securities are generally valued based upon quotes obtained from an independent third-party pricing service, 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.

Impaired Loans and Other Real Estate Owned. A loan is considered impaired when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Impairment is measured based on the fair value of the underlying collateral or the discounted expected future cash flows. The Company measures impairment on all 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 December 31, 2018, substantially all the Company’s impaired loans were evaluated based on the fair value of their underlying collateral based upon the most recent appraisal available to management and has recorded a specific reserve on one loan in the amount of $584,000 with a principal balance of $1.0 million.

The fair value of impaired loans and other real estate owned were determined using Level 3 assumptions, and represents impaired loan and other real estate owned balances for which a specific reserve has been established or on which a write down has been taken. Generally, the Company obtains third party appraisals (or property valuations) and/or collateral audits in conjunction with internal analysis based on historical experience on its impaired loans and other real estate owned to determine fair value. In determining the net realizable value of the underlying collateral for impaired loans, the Company will then discount the valuation to cover both market price fluctuations and selling costs the Company expected would be incurred in the event of foreclosure. In addition to the discounts taken, the Company’s calculation of net realizable value considered any other senior liens in place on the underlying collateral.

Reclassifications

Reclassifications. Some items in prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or stockholders’ equity.

Recent Accounting Pronouncements

Accounting Standards Adopted in 2018

In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 was signed into law, which among other things reduced the maximum federal corporate tax rate from 35% to 21%. This Update addresses concerns about the guidance in current U.S. GAAP that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date. That guidance is applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income (“AOCI”) were originally recognized in other comprehensive income (rather than in income from continuing operations). As a result of the adjustment of deferred taxes being required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income (referred to as stranded tax effects for purposes of this Update) did not reflect the appropriate tax rate. This Update allows for an election to reclassify between retained earnings and AOCI the impact of the federal income tax rate change. The amendments in this Update are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption of the amendments of this Update is permitted. The Company elected to early adopt in the first quarter of 2018. Accordingly, the Company recorded an increase to AOCI and a decrease to retained earnings of approximately $82,000 for stranded tax effects on available for sale investment securities in the first quarter of 2018.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. Under the current implementation guidance in Topic 805, there are three elements of a business-inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a “set”) that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this Update provide a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this Update (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The amendments provide a framework to assist entities in evaluating whether both an input and a substantive process are present. The framework includes two sets of criteria to consider that depend on whether a set has outputs. Although outputs are not required for a set to be a business, outputs generally are a key element of a business; therefore, the Company has developed more stringent criteria for sets without outputs. Lastly, the amendments in this Update narrow the definition of the term output so that the term is consistent with how outputs are described in Topic 606. Public business entities should apply the amendments in this Update to annual periods beginning after December 15, 2017, including interim periods within those periods. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This Update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In August 2016, the FASB issued ASU 2016-15, Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This Update provides guidance on eight specific cash flow classification issues, which include: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments or debt with coupon interest rates that are insignificant in relation to the effective interest rate; 3) contingent consideration payments made soon after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; 6) distributions received from equity method investments; 7) beneficial interest in securitization transactions; and 8) separately identifiable cash flows and the application of the predominance principle. The amendments in this Update are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period; however, an entity is required to adopt all of the amendments in the same period. The amendments in this Update should be applied using a retrospective transition method to each period presented. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, ASU 2018-04, Investments-Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No.33-9273 (SEC Update), ASU 2018-03, Technical Corrections and Improvements to Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. Changes made to the current measurement model primarily affect the accounting for equity securities with readily determinable fair values, where changes in fair value are included in earnings instead of other comprehensive income. The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged. This Update also changes the presentation and disclosure requirements for financial instruments including a requirement that public business entities use exit price when measuring the fair value of financial instruments measured at amortized cost for disclosure purposes. This Update is effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-01 did not have a material effect on the Company’s operating results or financial condition. In accordance with the guidance, the Company measures the fair value of financial instruments reported at amortized cost on the statement of financial condition using the exit price notion. For further details, refer to footnote Fair Value of Financial Instruments within these consolidated financial statements.

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. With this ASU, 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.

The Company adopted the provisions of ASU 2014-09 and its related amendments effective January 1, 2018 utilizing the modified retrospective transition method and determined the adoption was insignificant to the financial statements. Since the impact upon adoption of ASU 2014-09 and its related amendments was insignificant to the financial statements, a cumulative effect adjustment to retained earnings was not deemed necessary.

The Company’s review of its various revenue streams indicated that approximately 99% of the Company’s revenue is out of the scope of ASU 2014-09 and its related amendments, including all of the Company’s net interest income and a significant portion of non-interest income. For those revenue streams that are within the scope of ASU 2014-09 and its related amendments, the Company reviewed the associated customer contracts and agreements to determine the appropriate accounting for revenues under those contracts. The Company’s review did not identify any significant changes in the timing of revenue recognition under those contracts within the scope of ASU 2014-09 and its related amendments. Significant revenue streams that are within scope primarily relate to service charges and fees associated customer deposit accounts, as well as fees for various other services the Company provides its customers. As a result of the implementation of ASU 2014-09 and its related amendments, the Company conducts a detailed review of its revenue streams at least annually, or more frequently if deemed necessary.

Recent Accounting Guidance Not Yet Effective

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this Update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement.

The following disclosure requirements for public companies were removed from Topic 820:

• The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy.

• The policy for timing of transfers between levels.

• The valuation process for Level 3 fair value measurements.

The following disclosure requirements for public companies were modified in Topic 820:

• The amendments clarify that the measurement of uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date.

The following disclosure requirements for public companies were added to Topic 820:

• The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period

• The range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements

The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. In addition, an entity may early adopt any of the removed or modified disclosures immediately and delay adoption of the new disclosures until the effective date. The Company is currently evaluating the effects of ASU 2018-13 on its financial statements and disclosures.

In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchase Callable Debt Securities. This Update amends guidance on the amortization period of premiums on certain purchased callable debt securities. The amendments shorten the amortization period of premiums on purchased callable debt securities to the earliest call date. This Update should be applied on a modified retrospective basis through a cumulative-effect adjustment to beginning retained earnings. The effective date of ASU 2017-08 is for interim and annual reporting periods beginning after December 15, 2018. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This Update replaces the incurred loss impairment model in current U.S. GAAP with a model that reflects current expected credit losses (“CECL”). The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures. The Update requires that all expected credit losses for financial assets held at the reporting date be measured based on historical experience, current conditions and reasonable and supportable forecasts. The Update also requires enhanced disclosure, including qualitative and quantitative disclosures that provide additional information about significant estimates and judgments used in estimating credit losses. For public business entities, the Update is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures. The Company has formed a working group and a committee made up of members of finance, credit and risk management that are in the process of compiling and analyzing key data elements and implementing a software model that will meet the requirements of the new guidance. The Company has contracted with an industry expert to: (1) develop a new expected loss model with supportable assumptions, (2) identify data, reporting, and disclosure gaps, (3) provide quantitative modeling, and (4) assess, develop and document updates to accounting policies, new processes and controls. The magnitude of the adjustment and the overall impact of the new guidance on the consolidated financial statements cannot yet be reasonably estimated.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), ASU 2018-11, Leases (Topic 842): Targeted Improvements, ASU 2018-10, Codification Improvements to Topic 842, Leases. This Update is being issued to increase the transparency and comparability around lease obligations. Previously unrecorded off-balance sheet obligations will now be recorded in the consolidated financial statements, accompanied by enhanced qualitative and quantitative disclosures in the notes to the consolidated financial statements. The Update is generally effective for public business entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.

In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842): Targeted Improvements.  ASU 2018-10 provides improvements related to ASU 2016-02 to increase stakeholders’ awareness of the amendments to Topic 842 and to expedite the improvements.  The amendments affect narrow aspects of the guidance issued in ASU 2016-02.  ASU 2018-11 allows entities adopting ASU 2016-02 to choose an additional transition method, under which an entity initially applies the accounting guidance for leases under Topic 842 at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, ASU 2018-11 allows an entity electing this additional transition method to continue to present comparative period financial statements in accordance with Topic 840 (current U.S. GAAP).   ASU 2018-11 also allows lessors to not separate non-lease components from the associated lease component if certain conditions are met.  The amendments in these updates become effective for annual periods as well as interim periods within those annual periods beginning after December 15, 2018.

The Company has elected to apply the transition provisions of Topic 842 using the modified retrospective transition method, electing to adopt the “package” of practical expedients in its transition to Topic 842, as specified in ASC 842-10-65. The results of this policy election are that the Company will reflect the provisions of Topic 842 in its consolidated financial statements for the first time as of and for the period ended March 31, 2019 (the period of adoption). The Company will measure and record liabilities to make lease payments as well as right of use assets in the period of adoption for leases that existed as of the transition date, and will continue to present all comparative periods under Topic 840. Under this elected transition method, the Company is not required to reassess the following as part of its Transition to Topic 842: (1) whether any expired or existing contracts contain leases, (2) lease classifications for any existing or expired leases, and (3) initial direct costs for any existing leases. Additionally, the Company has elected to apply the use of hindsight in its assessment of the term for its leases upon transition, which allows for consideration of the Company’s option to extend or terminate a lease.

The Company is currently in the process of finalizing its transition accounting under Topic 842 and anticipates in the first quarter of 2019 it will record a liability to make future lease payments of approximately $43 million and right of use assets of approximately $41 million, the difference being the net of accounting adjustments previously recorded under Topic 840 and Topic 805, as required by transition guidance in ASC 842-10-65. The Company does not currently anticipate a cumulative effect adjustment to the opening balance of retained earnings will be required as part of its transition to Topic 842. The Company’s evaluation of lease obligations and service agreements under the new standard includes an assessment of the appropriate classification and related accounting of each lease agreement, a review of applicability of the new standard to existing service agreements and gathering all essential lease data to facilitate the application of the new standard. The Company’s review indicates that all of its leases are classified as operating leases or short-term leases. In accordance with the provisions of Topic 842, liabilities to make future lease payments and right of use assets will only be recorded for leases that are not considered short-term (leases with an original term of greater than 12 months). The Company will record expense for its leases on a straight-line basis in accordance with the requirements under Topic 842 for operating leases. The Company does not currently believe expense recognition for its operating leases (including short-term leases) under Topic 842 will differ significantly from that recorded under current lease accounting guidance. Right of use assets for operating leases will be amortized over the lease term and liabilities to make future lease payments will be accounted for using the interest method, both in accordance with Topic 842.
