HOPE BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. Hope Bancorp, Inc.

Hope Bancorp, Inc. (“Hope Bancorp” on a parent-only basis and the “Company” on a consolidated basis), headquartered in Los Angeles, California, is the holding company for Bank of Hope (the “Bank”). As of June 30, 2018, the Bank operated branches in California, Washington, Texas, Illinois, Alabama, Georgia, Virginia, New Jersey, and New York, loan production offices in Colorado, Texas, Oregon, Washington, Georgia, Virginia, Southern California, and Northern California, and a representative office in Seoul, Korea. The Company is a corporation organized under the laws of the state of Delaware and a bank holding company registered under the Bank Holding Company Act of 1956, as amended.

2. Basis of Presentation

The consolidated financial statements included herein have been prepared without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”), except for the Consolidated Statement of Financial Condition as of December 31, 2017 which was from the audited financial statements included in the Company’s 2017 Annual Report on Form 10-K. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such SEC rules and regulations.

The consolidated financial statements include the accounts of Hope Bancorp and its wholly owned subsidiaries, principally Bank of Hope. All intercompany transactions and balances have been eliminated in consolidation. The Company has made all adjustments, that in the opinion of management, are necessary to fairly present the Company’s financial position at June 30, 2018 and December 31, 2017 and the results of operations for the three and six months ended June 30, 2018 and 2017. Certain reclassifications have been made to prior period amounts to conform to the current year presentation. The results of operations for the interim periods are not necessarily indicative of results to be anticipated for the full year.

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“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 and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates.

These unaudited consolidated financial statements should be read along with the audited consolidated financial statements and accompanying notes included in the Company’s 2017 Annual Report on Form 10-K.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. Subsequently in July 2018, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842, Leases” and ASU 2018-11, “Leases Topic 842, Targeted Improvements”, to provide additional clarification, implementation, and transition guidance on certain aspects of ASU 2016-02. ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 and ASU 2018-10 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. Under ASU 2018-11, an additional transition option was provided that would allow entities to not apply the new guidance in the comparative periods they present in their financial statements in the year of adoption. Under this optional transition method, entities will be allowed to continue using and presenting leases under ASC 840 for prior years comparative periods and then prospectively adopt ASC 842 on January 1, 2019, recognizing a cumulative-effect adjustment to the opening balance of retained earnings. The Company estimated that there are approximately 100 operating leases that will be accounted for under ASU 2016-02 at the adoption date. The Company plans to elect the transition option to not reassess the following at adoption date: whether contracts are or contain leases, the lease classification for any expired or existing leases, and the evaluation of initial direct costs associated with existing leases. In July 2018, the Company engaged a new software vendor to assist the Company with the administration and accounting of leases under ASU 2016-02. The Company is currently in the process of evaluating the financial impact of the pending adoption of the new standard on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, also referred to as “CECL”. ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. ASU 2016-13 becomes effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. The Company has established a CECL committee to oversee the development and implementation of ASU 2016-13. The Company is collaborating with a third party advisory team and has completed a gap assessment, a full implementation road-map and a detailed project plan. The Company has also engaged a software vendor to assist the Company to build a model that is compliant with ASU 2016-13 by the effective date. Based on the Company’s initial assessment of the ASU 2016-13, the Company expects the new guidance will result in additional required allowance for loan losses which could potentially have a material impact on its consolidated financial statements and regulatory capital ratios.

In January 2017, the FASB issued ASU 2017-04, “Intangibles: Goodwill and Other: Simplifying the Test for Goodwill Impairment.” ASU 2017-04 will amend and simplify current goodwill impairment testing to eliminate Step 2 from the current provisions. Under the new guidance, an entity should perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. An entity still has the option to perform the quantitative assessment for a reporting unit to determine if a quantitative impairment test is necessary. ASU 2017-04 should be adopted for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of ASU 2017-04 is not expected to have a material impact on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities”. ASU 2017-08 was issued to amend the amortization period for certain callable debt securities held at a premium. ASU 2017-08 shortens the amortization period of premiums on certain purchased callable debt securities to the earliest call date. ASU 2017-08 affect all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date (that is, at a premium). ASU 2017-08 does not impact securities purchased at a discount, which continue to be amortized to maturity. ASU 2017-08 is effective for annual period beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted in an interim period. If an entity chooses to adopt early, any adjustments should be reflected as of the beginning of the fiscal year that includes the interim period. The adoption of ASU 2017-08 is not expected to have a material impact on the Company’s consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployees Share-Based Payment Accounting”. ASU 2018-07 expands the scope of Topic 718 (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services.  As ASU 2018-07 becomes effective, the accounting for share-based payments for nonemployees and employees will be substantially the same.  The ASU supersedes Subtopic 505-50, Equity – Equity-Based Payments to Non-Employees. ASU 2018-07 is effective for annual period beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted, but no earlier than a company’s adoption date of Topic 606, Revenue from Contracts with Customers.  The adoption of ASU 2018-07 is not expected to have a material impact on the Company’s consolidated financial statements as the Company has not historically issued share-based payments to nonemployees for goods and services.

3.    Stock-Based Compensation

The Company has a stock-based incentive plan (the “2016 Plan”) to award equity as a form of compensation. The 2016 Plan, was approved by the Company’s stockholders on September 1, 2016. The 2016 Plan provides for grants of stock options, stock appreciation rights (“SARs”), restricted stock, performance shares, and performance units (sometimes referred to individually or collectively as “awards”) to non-employee directors, employees, and consultants of the Company. Stock options may be either incentive stock options (“ISOs”), as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), or nonqualified stock options (“NQSOs”).

The 2016 Plan gives the Company flexibility to (i) attract and retain qualified non-employee directors, executives, other key employees, and consultants with appropriate equity-based awards to; (ii) motivate high levels of performance; (iii) recognize employee contributions to the Company’s success; and (iv) align the interests of the 2016 Plan participants with those of the Company’s stockholders. The plan initially had 2,400,000 shares available for grant to participants. The exercise price for shares under an ISO may not be less than 100% of fair market value on the date the award is granted under Code Section 422. Similarly, under the terms of the 2016 Plan, the exercise price for SARs and NQSOs may not be less than 100% of fair market value on the date of grant. Performance units are awarded to a participant at the market price of the Company’s common stock on the date of award (after the lapse of the restriction period and the attainment of the performance criteria). No minimum exercise price is prescribed for performance shares and restricted stock awarded under the 2016 Plan. All options not exercised generally expire 10 years after the date of grant.

ISOs, SARs and NQSOs have vesting periods of three to five years and have 10-year contractual terms. Restricted stock, performance shares, and performance units are granted with a restriction period of not less than one year from the grant date for performance-based awards and not more than three years from the grant date for time-based vesting of grants. Compensation expense for awards is recognized over the vesting period.

The Company had another stock-based incentive plan, the 2007 Equity Incentive Plan (“2007 Plan”), which was approved by stockholders in May 2007. Under the terms of this plan, awards cannot be granted under the plan more than ten years after the plan adoption date. Therefore, subsequent to May 2017, equity awards were not issued from this plan.

Under the 2016 Plan, 1,113,746 shares were available for future grants as of June 30, 2018.

The total shares reserved for issuance will serve as the underlying value for all equity awards under the 2016 Plan. With the exception of the shares underlying stock options and restricted stock awards, the board of directors may choose to settle the awards by paying the equivalent cash value or by delivering the appropriate number of shares.

The following is a summary of stock option activity under the 2016 Plan for the six months ended June 30,2018:

	Number of Shares		Weighted- Average Exercise Price Per Share		Weighted- Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value (Dollars in thousands)
Outstanding - January 1, 2018	1,075,423		$	15.06
Granted	—		—
Exercised	(16,742	)	11.76
Expired	(3,195	)	16.66
Forfeited	(24,000	)	17.18
Outstanding - June 30, 2018	1,031,486		$	15.06	6.82	$	2,861
Options exercisable - June 30, 2018	665,380		$	13.98	6.14	$	2,564

The following is a summary of restricted stock and performance unit activity under the 2016 Plan for the six months ended June 30,2018:

	Number of Shares		Weighted- Average Grant Date Fair Value
Outstanding - January 1, 2018	379,419		$	16.42
Granted	266,225		16.23
Vested	(63,105	)	15.51
Forfeited	(17,556	)	16.12
Outstanding - June 30, 2018	564,983		$	16.50

The total fair value of restricted stock and performance units vested for the six months ended June 30, 2018 and 2017 was $1.2 million and $1.3 million, respectively.

On August, 21, 2017 the Company adopted the Hope Employee Stock Purchase Plan (“ESPP”). The ESPP allows eligible employees to purchase the Company’s common shares through payroll deductions which build up between the offering date and the purchase date. At the purchase date, the Company uses the accumulated funds to purchase shares in the Company on behalf of the participating employees at a 10% discount to the closing price of the Company’s common shares. The closing price is the lower of either the closing price on the first day of the offering period or on the closing price on the purchase date. The dollar amount of common shares purchased under the ESPP must not exceed 20% of the participating employee’s base salary, subject to a cap of $25 thousand in stock value based on the grant date. The ESPP is considered compensatory under GAAP and compensation expense for the ESPP is recognized as part of the Company’s stock based compensation expenses. The compensation expense for ESPP during the six months ended June 30, 2018 and 2017 was $148 thousand and $0, respectively.

The amount charged against income related to stock-based payment arrangements, including ESPP, was $915 thousand and $760 thousand for the three months ended June 30, 2018 and 2017, respectively. For the six months ended June 30, 2018 and 2017, $1.9 million and $1.5 million, respectively, of stock-based payment arrangements were charged against income. The income tax benefit recognized was approximately $237 thousand and $292 thousand for the three months ended June 30, 2018 and 2017, respectively. The income tax benefit recognized for the six months ended June 30, 2018 and 2017, was approximately $482 thousand and $582 thousand, respectively.

At June 30, 2018, the unrecognized compensation expense related to non-vested stock option grants was $669 thousand which is expected to be recognized over a weighted average vesting period of 2.72 years. Unrecognized compensation expense related to non-vested restricted stock and performance units was $6.1 million which is expected to be recognized over a weighted average vesting period of 2.70 years.

4.    Earnings Per Share (“EPS”)

Basic EPS does not reflect the possibility of dilution that could result from the issuance of additional shares of common stock upon exercise or conversion of outstanding equity awards or convertible notes, and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if stock options or other contracts to issue common stock were exercised or converted to common stock that would then share in earnings. For the three months ended June 30, 2018 and 2017, stock options and restricted shares awards for 306,136 and 530,334 shares of common stock, respectively, were excluded in computing diluted earnings per common share because they were anti-dilutive. For the six months ended June 30, 2018 and 2017, stock options and restricted shares awards for 303,338 and 542,328 shares of common stock, respectively, were excluded in computing diluted earnings per common share because they were anti-dilutive. Additionally, warrants issued pursuant to the Company’s participation in the U.S. Treasury’s TARP Capital Purchase Plan, to purchase 20,673 shares and 20,087 shares of common stock were anti-dilutive and excluded for the three and six months ended June 30, 2018 and 2017, respectively.

During the second quarter of 2018, the Company issued $217.5 million in convertible notes. The convertible notes can be converted to the Company’s shares of common stock at an initial rate of 45.0760 shares per $1,000 principal amount of the notes (See footnote 10 “Subordinated Debentures and Convertible Notes” for additional information regarding convertible notes issued). For the three and six months ended June 30, 2018, shares related to the convertible notes issued were not included in the Company’s diluted EPS calculation. In accordance with the terms of the convertible notes and settlement options available to the Company, no shares would have been delivered to investors of the convertible notes upon assumed conversion based on the Company’s common stock price during the three and six months ended June 30, 2018.

On April 26, 2018, the Company’s Board of Directors approved a share repurchase program that authorized the Company to repurchase up to $100.0 million in common stock. During the second quarter of 2018, the Company repurchased 4.4 million shares of common stock totaling $79.0 million which were recorded as treasury stock and these shares were excluded from weighted average shares and weighted average diluted shares for the three and six months ended June 30, 2018 after they were repurchased.

5.    Equity Investments

On January 1, 2018, the Company adopted ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities”. As a result of the adoption, the Company reclassified $469 thousand in net unrealized losses included in other comprehensive income and deferred tax assets as of December 31, 2017 to retained earnings on January 1, 2018. Equity investments with readily determinable fair value at June 30, 2018, consisted of mutual funds and equity stock in other institutions in the amount of $21.4 million and $4.1 million, respectively and is included in “Interest bearing deposits in other financial institutions and other investments” on the consolidated statements of financial condition.

In accordance with ASU 2016-01, the change in fair value for equity investments with readily determinable fair value for the three and six months ended June 30, 2018 were recorded as other noninterest income as summarized in the table below:

	Three Months Ended June 30, 2018			Six Months Ended June 30, 2018
	(Dollars in thousands)
Net change in fair value recorded during the period on equity investment securities	$	(1	)	$	3,518
Net change in fair value recorded on equity investment securities sold during the period	—			—
Net change in fair value on equity investment securities at end of period	$	(1	)	$	3,518

At June 30, 2018, the Company also had equity investment without readily determinable fair value which are carried at cost less any determined impairment. The balance of these investments are adjusted for changes in subsequent observable prices. At June 30, 2018 the total balance of equity investments without readily determinable fair values included in “Interest bearing deposits in other financial institutions and other investments” on the consolidated statements of financial condition was $18.2 million, consisting of $370 thousand in correspondent bank stock and community reinvestment act investments of $17.8 million. There was no impairment or subsequent observable price changes for investments without readily determinable fair values for the three and six month ended June 30, 2018.

There were no reclassifications out of accumulated other comprehensive loss into earnings during the three and six months ended June 30, 2018 or 2017.

On January 1, 2018, the Company adopted ASU 2016-01 “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities”. As a result of the adoption of ASU 2016-01, the Company no longer accounts for mutual funds as available-for-sale securities and accounts for these investments as equity investments with readily determinable fair value with changes in fair value recorded through earnings. In accordance with ASU 2016-01, the Company reclassified $469 thousand in net unrealized losses included in other comprehensive income and deferred tax assets as of December 31, 2017 to retained earnings on January 1, 2018. The subsequent changes to fair value for mutual funds were recorded as other noninterest income for the three and six months ended June 30, 2018.

* Investments in U.S. Government agency and U.S. Government sponsored enterprises

The Company evaluates securities for other-than-temporary-impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to the financial condition and near-term prospects of the issuer, the length of time and the extent to which the fair values of the securities have been less than the cost of the securities, and management’s intention to sell, or whether it is more likely than not that management will be required to sell the security in an unrealized loss position before recovery of its amortized cost basis. In analyzing an issuer’s financial condition, the Company considers, among other considerations, whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition.

The Company had collateralized mortgage obligations, mortgage backed securities, and municipal securities that were in a continuous unrealized loss position for twelve months or longer as of June 30, 2018. The collateralized mortgage obligations in a continuous loss position for twelve months or longer had unrealized losses of $19.0 million at June 30, 2018 and total mortgage backed securities in a continuous loss position for twelve months or longer had total unrealized losses of $18.8 million. These securities were issued by U.S. Government agency and U.S. Government sponsored enterprises and have high credit ratings of “AA” grade or better. Interest on U.S. Government agency and U.S. Government sponsored enterprise investments have been paid as agreed, and management believes this will continue in the future and that the securities will be repaid in full as scheduled. Municipal securities that were in a continuous loss position for twelve months or longer had unrealized losses of $1.6 million at June 30, 2018. The market value declines for these securities were primarily due to movements in interest rates and are not reflective of management’s expectations of the Company’s ability to fully recover these investments, which may be at maturity. For these reasons, no OTTI was recognized on U.S. Government sponsored collateralized mortgage obligations and mortgage backed securities, and municipal securities that were in an unrealized loss position at June 30, 2018.

The Company considers the losses on the investments in unrealized loss positions at June 30, 2018 to be temporary based on: 1) the likelihood of recovery; 2) the information relative to the extent and duration of the decline in market value; and 3) the Company’s intention not to sell, and management’s determination that it is more likely than not that the Company will not be required to sell a security in an unrealized loss position before recovery of its amortized cost basis.

The loan portfolio is made up of four segments: real estate loans, commercial business, trade finance, and consumer and other. These segments are further segregated between loans accounted for under the amortized cost method (“Legacy Loans”) and previously acquired loans that were originally recorded at fair value with no carryover of the related pre-acquisition allowance for loan losses (“Acquired Loans”). Acquired Loans are further segregated between purchased credit impaired loans (loans with credit deterioration on the acquisition date and accounted for under ASC 310-30, or “PCI loans”) and Acquired Performing Loans (loans that were pass graded on the acquisition date and the fair value adjustment is amortized over the contractual life under ASC 310-20, or “non-PCI loans”).

The following table presents changes in the accretable discount on the PCI loans for the three and six months ended June 30, 2018 and 2017:

	Three Months Ended June 30,						Six Months Ended June 30,
	2018			2017			2018			2017
	(Dollars in thousands)
Balance at beginning of period	$	54,846		$	51,651		$	55,002		$	43,611
Accretion	(5,959		)	(5,212		)	(11,731		)	(10,560		)
Reclassification from nonaccretable difference	4,686			7,218			10,302			20,606
Balance at end of period	$	53,573		$	53,657		$	53,573		$	53,657

On the acquisition date, the amount by which the undiscounted expected cash flows exceed the estimated fair value of the PCI loans is the “accretable yield.” The accretable yield is then measured at each financial reporting date and represents the difference between the remaining undiscounted expected cash flows and the current carrying value of the loans. The accretable yield will change from period to period due to the following: 1) estimates of the remaining life of acquired loans will affect the amount of future interest income; 2) indices for variable rates of interest on PCI loans may change; and 3) estimates of the amount of the contractual principal and interest that will not be collected (nonaccretable difference) may change.

Generally, loans are placed on nonaccrual status if the principal and/or interest payments become 90 days or more past due and/or management deems the collectability of the principal and/or interest to be in question, as well as when required by regulatory requirements. Loans to customers whose financial condition has deteriorated are considered for nonaccrual status whether or not the loan is 90 days or more past due. Generally, payments received on nonaccrual loans are recorded as principal reductions. Loans are returned to accrual status only when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The Company did not recognize any cash basis interest income for the three and six months ended June 30, 2018 or 2017.

The following table represent the recorded investment in nonaccrual and loans past due over 90 days or more and still on accrual status by class of loans as of June 30, 2018 and December 31, 2017.

⁽¹⁾  Acquired Loans exclude PCI loans.

Loans accounted for under ASC 310-30 are generally considered accruing and performing loans and the accretable discount is accreted to interest income over the estimated life of the loan when cash flows are reasonably estimable. Accordingly, PCI loans that are contractually past due are still considered to be accruing and performing loans. The loans may be classified as nonaccrual if the timing and amount of future cash flows is not reasonably estimable.

27

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including, but not limited to, current financial information, historical payment experience, credit documentation, public information, and current economic trends. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes all non-homogeneous loans. Homogeneous loans are not risk rated and credit risk is analyzed largely by the number of days past due. This analysis is performed at least on a quarterly basis. The definitions for risk ratings are as follows:

• Pass: Loans that meet a preponderance or more of the Company’s underwriting criteria and evidence an acceptable level of risk.

• Special Mention: Loans that have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

• Substandard: Loans that are inadequately protected by the current net worth and paying capacity of the borrower or by the collateral pledged, if any. Loans in this classification have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

• Doubtful: Loans that have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or repayment in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

The following tables present the recorded investment of risk ratings for Legacy and Acquired Loans as of June 30, 2018 and December 31, 2017 by class of loans:

The Company may reclassify loans held for investment to loans held for sale in the event that the Company plans to sell loans that were originated with the intent to hold to maturity. Loans transferred from held to investment to held for sale are carried at the lower of cost or fair value. The breakdown of loans by type that were reclassified from held to investment to held for sale for the three and six months ended June 30, 2018 and 2017 is presented in the following table:

The adequacy of the allowance for loan losses is determined by management based upon an evaluation and review of the credit quality of the loan portfolio, consideration of historical loan loss experience, relevant internal and external factors that affect the collection of a loan, and other pertinent factors.

29

Migration analysis is a formula methodology derived from the Bank’s actual historical net charge off experience for each loan class (type) or pool and risk grade. The migration analysis is centered on the Bank’s internal credit risk rating system. Management’s internal loan review and external contracted credit review examinations are used to determine and validate loan risk grades. This credit review system takes into consideration factors such as: borrower’s background and experience; historical and current financial condition; credit history and payment performance; economic conditions and their impact on various industries; type, fair value and volatility of the fair value of collateral; lien position; and the financial strength of any guarantors.

A general loan loss allowance is provided on loans not specifically identified as impaired (“non-impaired loans”). The Bank’s general loan loss allowance has two components: quantitative and qualitative risk factors. The quantitative risk factors are based on the migration analysis methodology described above. The loans are classified by class and risk grade, and the historical loss migration is tracked for the various classes. Loss experience is quantified for a specified period and then weighted to place more significance on the most recent losses. That loss experience is then applied to the stratified portfolio at the end of each quarter. The Company utilizes nineteen non-homogeneous loan pools in the quantitative analysis process. The non-impaired commercial real estate loan portfolio is stratified into fourteen different loan pools based on property types and the non-impaired commercial and industrial loan portfolio is stratified into five different loan pools based on loan type in order to allocate historic loss experience to more granular loan pools.

Additionally, in order to systematically quantify the credit risk impact of other trends and changes within the loan portfolio, the Bank utilizes qualitative adjustments to the migration analysis within established parameters. The parameters for making adjustments are established under a Credit Risk Matrix that provides seven possible scenarios for each of the factors below. The matrix allows for up to three positive (Major, Moderate, and Minor), three negative (Major, Moderate, and Minor), and one neutral credit risk scenarios within each factor for each loan type or pool. However, if information exists to warrant adjustment to the migration analysis, changes are made in accordance with the established parameters supported by narrative and/or statistical analysis. The Credit Risk Matrix and the nine possible scenarios enable the Bank to qualitatively adjust the Loss Migration Ratio by as much as 50 basis points in either direction (positive or negative) for each loan type pool. This matrix considers the following nine factors, which are patterned after the guidelines provided under the FFIEC Interagency Policy Statement on the Allowance for Loan and Lease Losses:

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

• Changes in national and local economic and business conditions and developments, including the condition of various market segments;

• Changes in the nature and volume of the loan portfolio;

• Changes in the experience, ability and depth of lending management and staff;

• Changes in the trends of the volume and severity of past due loans, classified loans, nonaccrual loans, troubled debt restructurings and other loan modifications;

• Changes in the quality of the loan review system and the degree of oversight by the Directors;

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

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

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

The Company also establishes specific loss allowances for loans that have identified potential credit risk conditions or circumstances related to a specific individual credit. The specific allowance amounts are determined in accordance with ASC 310-10-35-22, “Measurement of Impairment.” The loans identified as impaired will be accounted for in accordance with one of the three acceptable valuation methods: 1) the present value of future cash flows discounted at the loan’s effective interest rate; 2) the loan’s observable market price; or 3) the fair value of the collateral, if the loan is collateral dependent. For the collateral dependent impaired loans, management obtains a new appraisal to determine the amount of impairment as of the date that the loan became impaired. The appraisals are based on an “as is” valuation. To ensure that appraised values remain current, management either obtains updated appraisals every twelve months from a qualified independent appraiser or an internal evaluation of the collateral is performed by qualified personnel. If the third party market data indicates that the value of the collateral property has declined since the most recent valuation date, management adjusts the value of the property downward to reflect current market conditions. If the fair value of the collateral is less than the recorded amount of the loan, management recognizes impairment by creating or adjusting an existing valuation allowance with a corresponding charge to the provision for loan losses. If an impaired loan is expected to be collected through liquidation or operation of the underlying collateral, the loan is deemed to be collateral dependent and the amount of impairment is charged off against the allowance for loan losses.

30

The Company considers a loan to be impaired when it is probable that not all amounts due (principal and interest) will be collectible in accordance with the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The significance of payment delays and payment shortfalls is determined on a case-by-case basis by taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed.

For commercial business loans, real estate loans, and certain consumer loans, management bases the measurement of loan impairment on the present value of the expected future cash flows, discounted at the loan’s effective interest rate, or on the fair value of the loan’s collateral if the loan is collateral dependent. The scope for evaluation of individual impairment includes all loans risk graded Doubtful or Loss, all troubled debt restructured loans (“TDRs”) and all loans risk graded Substandard that are greater than $500 thousand regardless of performance under their contractual terms. Management evaluates most consumer loans for impairment on a collective basis because these loans generally have smaller balances and are homogeneous in the underwriting of terms and conditions and in the types of collateral. If a loan is deemed to be impaired, the amount of the impairment is supported by a specific allowance amount which is included in the allowance for loan losses through a charge to the provision for loan losses.

For PCI loans, the allowance for loan losses is based upon expected cash flows for these loans. To the extent that a deterioration in borrower’s credit quality results in a decrease in expected cash flows subsequent to the acquisition of the loans, an allowance for loan losses would be established based on an estimate of future credit losses over the remaining life of the loans. Credit for loan losses on acquired loans for the three months ended June 30, 2018 was $253 thousand which included $449 thousand in credit for loan losses related to PCI loans. Credit for loan losses on acquired loans for the six months ended June 30, 2018 was $2.5 million which included $637 thousand in credit for loan losses related to PCI loans.

Under certain circumstances, the Company provides borrowers relief through loan modifications. These modifications are either temporary in nature (“temporary modifications”) or are more substantive. The temporary modifications generally consist of interest only payments for a three to six month period, whereby principal payments are deferred. At the end of the modification period, the remaining principal balance is re-amortized based on the original maturity date. Loans subject to temporary modifications are generally downgraded to Special Mention or Substandard. At the end of the modification period, the loan either 1) returns to the original contractual terms; 2) is further modified and accounted for as a troubled debt restructuring in accordance with ASC 310-10-35; or 3) is disposed of through foreclosure or liquidation.

Troubled Debt Restructurings (“TDRs”) of loans are defined by ASC 310-40, “Troubled Debt Restructurings by Creditors” and evaluated for impairment in accordance with ASC 310-10-35. The concessions may be granted in various forms, including reduction in the stated interest rate, reduction in the amount of principal amortization, forgiveness of a portion of a loan balance or accrued interest, or extension of the maturity date. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed on the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Bank’s internal underwriting policy. At June 30, 2018, total TDR loans were $69.6 million, compared to $78.5 million at December 31, 2017.

A summary of the recorded investment of TDRs on accrual and nonaccrual status by type of concession as of June 30, 2018 and December 31, 2017 is presented below:

TDRs on accrual status are comprised of loans that were accruing at the time of restructuring and for which the Bank anticipates full repayment of both principal and interest under the restructured terms. TDRs that are on nonaccrual status can be returned to accrual status after a period of sustained performance, generally determined to be six months of timely payments as modified.  Sustained performance includes the periods prior to the modification if the prior performance met or exceeded the modified terms. TDRs on accrual status at June 30, 2018 were comprised of 21 commercial real estate loans totaling $26.3 million, 35 commercial business loans totaling $15.7 million, and 43 other loans totaling $7.2 million. TDRs on accrual status at December 31, 2017 were comprised of 24 commercial real estate loans totaling $32.8 million, 27 commercial business loans totaling $27.0 million and 56 other loans totaling $7.5 million. The Company expects that TDRs on accrual status as of June 30, 2018, which were all performing in accordance with their restructured terms, to continue to comply with the restructured terms because of the reduced principal or interest payments on these loans. TDRs that were restructured at market interest rates and had sustained performance as agreed under the modified loan terms may be reclassified as non-TDRs after each year end but are reserved for under ASC 310-10.

The Company has allocated $3.9 million and $4.8 million of specific reserves to TDRs as of June 30, 2018 and December 31, 2017, respectively.

9.    Borrowings

The Company maintains a line of credit with the Federal Home Loan Bank (“FHLB”) of San Francisco as a secondary source of funds. The borrowing capacity with the FHLB is limited to the lower of 25% of the Bank’s total assets or the Bank’s collateral capacity, which was $3.63 billion at June 30, 2018, and $3.54 billion at December 31, 2017. The terms of this credit facility require the Company to pledge eligible collateral with the FHLB equal to at least 100% of outstanding advances.

At June 30, 2018 and December 31, 2017, real estate secured loans with a carrying amount of approximately $5.82 billion and $4.91 billion, respectively, were pledged at the FHLB for outstanding advances and remaining borrowing capacity. At June 30, 2018 and December 31, 2017, other than FHLB stock, no securities were pledged as collateral at FHLB. The purchase of FHLB stock is a prerequisite to become a member of the FHLB system, and the Company is required to own a certain amount of FHLB stock based on outstanding borrowings.

At June 30, 2018 and December 31, 2017, FHLB advances totaling $837.0 million and $1.16 billion, respectively, had weighted average effective interest rates of 1.76% and 1.63%, respectively. FHLB advances at June 30, 2018 and December 31, 2017 had various maturities through December 2022. The effective interest rate of FHLB advances as of June 30, 2018 ranged between 1.06% and 2.39%. At June 30, 2018, the Company’s remaining borrowing capacity with the FHLB was $2.76 billion.

At December 31, 2017, the Company also had $69.9 million in overnight federal funds purchased from lines at other banks. There were no federal funds purchased from other banks at June 30, 2018.

At June 30, 2018, the contractual maturities for FHLB advances were as follows:

	June 30, 2018
Scheduled maturities in:	(Dollars in thousands)
2018	$	40,000
2019	320,000

10.    Subordinated Debentures and Convertible Notes

Subordinated Debt

At June 30, 2018, the Company had nine wholly owned subsidiary grantor trusts that had issued $126.0 million of pooled trust preferred securities. Trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in the indentures. The trusts used the net proceeds from the offering to purchase a like amount of subordinated debentures (the “Debentures”). The Debentures are the sole assets of the trusts. The Company’s obligations under the subordinated debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon the maturity of the Debentures, or upon earlier redemption as provided in the indentures. The Company has the right to redeem the Debentures in whole (but not in part) on a quarterly basis at a redemption price specified in the indentures plus any accrued but unpaid interest to the redemption date. The Company also has a right to defer consecutive payments of interest on the debentures for up to five years.

The following table is a summary of trust preferred securities and Debentures at June 30, 2018:

Issuance Trust	Issuance Date	Trust Preferred Security Amount		Carrying Value of Debentures		Rate Type	Current Rate	Maturity Date
		(Dollars in thousands)
Nara Capital Trust III	06/05/2003	$	5,000	$	5,155	Variable	5.49%	06/15/2033

Wilshire Statutory Trust III	09/15/2005	15,000		10,857		Variable	3.74%	09/15/2035
Wilshire Statutory Trust IV	07/10/2007	25,000		17,618		Variable	3.72%	09/15/2037
Saehan Capital Trust I	03/30/2007	20,000		14,700		Variable	3.96%	06/30/2037
Total		$	126,000	$	101,386

The Company’s investment in the common trust securities of the issuer trusts was $3.9 million at June 30, 2018 and is included in other assets. Although the subordinated debt issued by the trusts is not included as a component of stockholders’ equity in the consolidated statements of financial condition, the debt is treated as capital for regulatory purposes. The trust preferred security debt issuances are includable in Tier I capital up to a maximum of 25% of capital on an aggregate basis. Any amount that exceeds 25% qualifies as Tier 2 capital.

Under the “Merger and Acquisition Transition Provisions” in BASEL III, if a depository institution holding company of $15 billion or more acquires a depository institution holding company with total consolidated assets of less than $15 billion as of December 31, 2009, the non-qualifying capital instruments of the resulting organization will be subject to a phase-out schedule. The phase-out schedule ended in 2016 and therefore in accordance with BASEL III, the Company’s subordinated debenture will no longer qualify for Tier 1 capital treatment once the Company exceeds total consolidated assets of $15 billion or more since the Company had acquisitions subsequent to December 31, 2009. The subordinated debentures will be still be eligible for Tier 2 inclusion once the Company exceeds $15 billion or more in total consolidated assets.

Convertible Notes

On May 11, 2018, the Company issued $200 million aggregate principal amount of 2.00% convertible senior notes maturing on May 15, 2038 in a private offering to qualified institutional investors under Rule 144A of the Securities Act of 1933. Subsequently on June 7, 2018, an additional $17.5 million in convertible notes were issued as part of the initial offering over-allotment option. In total, the Company issued $217.5 million in convertible notes during the second quarter of 2018. The convertible notes can be converted to the Company’s share of common stock at an initial rate of 45.0760 shares per $1,000 principal amount of the notes (equivalent to an initial conversion price of approximately $22.18 per share of common stock which represents a premium of 22.5% to the closing stock price on the date of the pricing of the notes). The convertible notes can be called by the Company, in part or in whole, on or after May 20, 2023 for 100% of the principal amount in cash. Holders of the convertible notes also have the option to repurchase or put the notes on May 15, 2023, May 15, 2028, or May 15, 2033 for 100% of the principal amount in cash.

40

The convertible notes were issued as part of the Company’s plan to repurchase its common stock. On April 26, 2018, the Company’s Board of Directors approved a share repurchase program that authorized the Company to use up to $100.0 million of the proceeds from the convertible notes offering to repurchase its common stock. The net proceeds from the offering, after deducting the initial purchaser’s discount, was approximately $213.2 million. Of the total net proceeds, $113.2 million was down-streamed to the Bank as equity and the remaining $100.0 million was allocated for share repurchases. The Company used approximately $76.0 million of the allocated $100.0 million for share repurchases to repurchase shares of its common stock from purchasers of the convertible notes in privately negotiated transactions at a purchase price per share equal to the $18.11 per share closing price of the Company’s common stock. Subsequently, the Company repurchased additional shares of common stock on the open market. At June 30, 2018, total shares repurchased by the Company was $79.0 million, or 4.4 million shares at a weighted average price of $18.1032.

In accordance with accounting principles, the convertible notes issued by the Company were separated into a debt component and an equity component which represents the stock conversion option. The present value of the convertible notes was calculated based on a discount rate of 4.25%, which represented the current offering rate for similar types of debt without conversion options. The effective life of the convertible notes was estimated to be five years based on the first call and put date. The difference between the principal amount of the notes and the present value was recorded as the convertible note discount and additional paid-in capital. The issuance costs related to the offering were also allocated into a debt component to be capitalized, and an equity component in the same percentage allocation of debt and equity of the convertible note. The value of the convertible note at issuance and carrying value as of June 30, 2018 is presented below:

11.    Derivative Financial Instruments

The Company offers a loan hedging program to certain loan customers. Through this program, the Company originates a variable rate loan with the customer. The Company and the customer will then enter into a fixed interest rate swap. Lastly, an identical offsetting swap is entered into by the Company with a correspondent bank. These “back-to-back” swap arrangements are intended to offset each other and allow the Company to book a variable rate loan, while providing the customer with a contract for fixed interest payments. In these arrangements, the Company’s net cash flow is equal to the interest income received from the variable rate loan originated with the customer. These customer swaps are not designated as hedging instruments and are recorded at fair value in other assets and other liabilities. The changes in fair value is recognized in the income statement in other income and fees.

At June 30, 2018 and December 31, 2017, interest rate swaps related to the Company’s loan hedging program that were outstanding is presented in the following table:

The Company enters into various stand-alone mortgage-banking derivatives in order to hedge the risk associated with the fluctuation of interest rates. Changes in fair value are recorded as mortgage banking revenue. Residential mortgage loans funded with interest rate lock commitments and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. At June 30, 2018, the Company had approximately $2.1 million in interest rate lock commitments and total forward sales commitments for the future delivery of residential mortgage loans. At December 31, 2017, the Company had approximately $4.8 million in interest rate lock commitments and total forward sales commitments for the future delivery of residential mortgage loans.

The following table reflects the notional amount and fair value of mortgage banking derivatives for the dates indicated:

12.    Commitments and Contingencies

In the normal course of business, the Company is a party to financial instruments with off-balance sheet risk that are used to meet the financing needs of customers. These financial instruments include commitments to extend credit, standby letters of credit, commercial letters of credit, commitments to fund investments in affordable housing partnerships, mortgage derivatives, and operating lease commitments. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. The Company’s exposure to credit loss in the event of nonperformance on commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as the Company does for extending loan facilities to customers. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on the Company’s credit evaluation of the counterparty. The types of collateral that the Company may hold can vary and may include accounts receivable, inventory, property, plant and equipment, and income-producing properties.

Commitments at June 30, 2018 and December 31, 2017 are summarized as follows:

	June 30, 2018		December 31, 2017
	(Dollars in thousands)
Commitments to extend credit	$	1,676,694	$	1,526,981
Standby letters of credit	77,758		74,748
Other letters of credit	125,630		74,147
Commitments to fund investments in affordable housing partnerships	38,056		38,467
Interest rate lock	2,107		4,795
Forward sale commitments	2,107		4,795
Operating lease commitments	69,304		66,698

In the normal course of business, the Company is involved in various legal claims. The Company has reviewed all legal claims against us with counsel and have taken into consideration the views of such counsel as to the potential outcome of the claims. Loss contingencies for all legal claims totaled $420 thousand at June 30, 2018 and $414 thousand at December 31, 2017. It is reasonably possible the Company may incur losses in addition to the amounts currently accrued. However, at this time, the Company is unable to estimate the range of additional losses that are reasonably possible because of a number of factors, including the fact that certain of these litigation matters are still in their early stages and involve claims that the Company believes have little to no merit. Management has considered these and other possible loss contingencies and does not expect the amounts to be material to the consolidated financial statements.

13.    Goodwill, Intangible Assets, and Servicing Assets

Goodwill represents the excess of the purchase price over the sum of the estimated fair values of the tangible and identifiable intangible assets acquired less the estimated fair value of the liabilities assumed. Goodwill has an indefinite useful life and is evaluated for impairment annually or more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. At December 31, 2017, management assessed the qualitative factors related to intangible assets and goodwill and for the year to determine whether it was more-likely-than-not that the fair value was less than its carrying amount. Based on the analysis of these factors, management determined that it was more-likely-than-not that intangible assets were not impaired and that the fair value of goodwill exceeded the carrying value and that the two-step goodwill impairment test was not needed. Goodwill is not amortized for book purposes and is not tax deductible.

The carrying amount of the Company’s goodwill as of June 30, 2018 and December 31, 2017 was $464.5 million. There was no impairment of goodwill during the three and six months ended June 30, 2018.

Core deposit intangible assets are amortized over their estimated lives, which range from seven to ten years. Amortization expense related to core deposit intangible assets totaled $615 thousand and $676 thousand for the three months ended June 30, 2018 and 2017, respectively. The amortization expense related to core deposit intangible assets totaled $1.2 million and $1.4 million for the six months ended June 30, 2018 and 2017, respectively. The following table provides information regarding the core deposit intangibles at June 30, 2018:

		As of June 30, 2018
Core Deposit Intangibles Related To:	Amortization Period	Gross Carrying Amount		Accumulated Amortization			Carrying Amount

Total		$	25,605	$	(10,313	)	$	15,292

Servicing assets are recognized when SBA and residential mortgage loans are sold with servicing retained with the income statement effect recorded in gains on sales of loans. Servicing assets are initially recorded at fair value based on the present value of the contractually specified servicing fee, net of 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 40 basis points. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans.

Management periodically evaluates servicing assets for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is determined by stratifying rights into groupings based on loan type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. As of June 30, 2018 and December 31, 2017, the Company did not have a valuation allowance for servicing assets.

The changes in servicing assets for the three and six months ended June 30, 2018 and 2017 were as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2018			2017			2018			2017
	(Dollars in thousands)
Balance at beginning of period	$	24,866		$	25,941		$	24,710		$	26,457
Additions through originations of servicing assets	1,600			1,316			3,316			2,612
Amortization	(2,086		)	(1,919		)	(3,646		)	(3,731		)
Adjustments	670			—			670			—
Balance at end of period	$	25,050		$	25,338		$	25,050		$	25,338

Loans serviced for others are not reported as assets. The principal balances of loans serviced for other institutions were $1.54 billion as of June 30, 2018 and $1.51 billion as of December 31, 2017.

44

The Company utilizes the discounted cash flow method to calculate the initial excess servicing assets. The inputs used in evaluating servicing assets for impairment at June 30, 2018 and December 31, 2017 are presented below.

	June 30, 2018	December 31, 2017
SBA Servicing Assets:
Weighted-average discount rate	12.09%	11.13%
Constant prepayment rate	9.99%	8.38%
Mortgage Servicing Assets:
Weighted-average discount rate	10.13%	9.63%
Constant prepayment rate	7.65%	9.05%

14.    Income Taxes

For the three months ended June 30, 2018, the Company had an income tax provision totaling $16.6 million on pretax income of $64.2 million, representing an effective tax rate of 25.92%, compared with an income tax provision of $25.5 million on pretax income of $66.1 million, representing an effective tax rate of 38.48% for the three months ended June 30, 2017. For the six months ended June 30, 2018, the Company had an income tax provision totaling $34.4 million on pretax income of $133.1 million, representing an effective tax rate of 25.81%, compared with an income tax provision of $48.5 million on pretax income of $125.3 million, representing an effective tax rate of 38.65% for the six months ended June 30, 2017. The reduction in effective tax rate for periods in 2018 compared to periods 2017 was primarily due to the reduction of federal income tax rate from 35% to 21% under comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (“Tax Act”) effective as of December 22, 2017, but the increase in affordable housing partnership investment tax credits for the three and six months ended June 30, 2018 compared to the three and six months ended June 30, 2017, also contributed to the decline in the tax rate.

As of June 30, 2018, the Company has not yet completed accounting for the enactment of the Tax Act; however, the Company believes it has reasonably estimated the effects of the Tax Act by recording an income tax expense of $25.4 million for the year ended December 31, 2017 in accordance with SEC Staff Accounting Bulletin No. 118 (“SAB 118”). As required by SAB 118, the Company will continue to evaluate and re-measure the impact of the Tax Act on deferred tax amounts that existed at December 31, 2017 and record appropriate income tax provision amounts in 2018. As a result of this process, through the second quarter of 2018, the Company recorded an additional income tax provision expense of $16 thousand for the six months ended June 30, 2018.

The Company and its subsidiaries are subject to U.S. federal income tax, as well as state income taxes. The Company had total unrecognized tax benefits of $2.4 million at June 30, 2018 and $2.1 million at December 31, 2017, that relate to uncertainties associated with federal and state income tax matters. The Company recognizes interest and penalties on income tax matters in income tax expense. The Company recorded approximately $438 thousand and $348 thousand, for accrued interest (no portion was related to penalties) at June 30, 2018 and December 31, 2017, respectively.

Management believes it is reasonably possible that the unrecognized tax benefits may decrease by $2.4 million in the next twelve months due to a settlement with the state tax authorities.

The statute of limitations for the assessment of income taxes 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 for the assessment of income and franchise taxes related to the various state income and franchise tax returns varies by state. The Company is currently under examination by the California Franchise Tax Board (FTB) for the 2011, 2012 and 2013 tax years and by the New York State Department of Taxation and Finance for the 2013, 2014, and 2015 tax years. Wilshire Bancorp, Inc., an acquired entity, is currently under examination by the FTB for the 2011, 2012, and 2013 tax years. While the outcome of the examinations is unknown, the Company expects no material adjustments.

Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities (without regard to certain changes to deferred taxes). Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In assessing the realization of deferred tax assets, management evaluates both positive and negative evidence, including the existence of any cumulative losses in the current year and the prior two years, the amount of taxes paid in available carry-back years, the forecasts of future income, applicable tax planning strategies, and assessments of current and future economic and business 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 June 30, 2018.

15.    Fair Value Measurements

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair value. The fair value inputs of the instruments are classified and disclosed in one of the following categories pursuant to ASC 820:

Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. The quoted price shall not be adjusted for any blockage factor (i.e., size of the position relative to trading volume).

Level 2 - Pricing inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Fair value is determined through the use of models or other valuation methodologies, including the use of pricing matrices. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 - Pricing inputs are unobservable for the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. The inputs into the determination of fair value require significant management judgment or estimation.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

The Company uses the following methods and assumptions in estimating fair value disclosures for financial instruments. Financial assets and liabilities recorded at fair value on a recurring and non-recurring basis are listed as follows:

Securities Available for Sale

The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs).

The fair values of the Company’s Level 3 securities available for sale were measured using an income approach valuation technique. The primary inputs and assumptions used in the fair value measurement were derived from the securities’ underlying collateral, which included discount rates, prepayment speeds, payment delays, and an assessment of the risk of default of the underlying collateral, among other factors. Significant increases or decreases in any of the inputs or assumptions would result in a significant increase or decrease in the fair value measurement.

Equity Investments With Readily Determinable Fair Value

The fair value of our equity investments with readily determinable fair value is comprised of mutual funds and equity stock. The fair value for these investments is obtained from unadjusted quoted prices in active markets on the date of measurement and is therefore classified as Level 1.

Interest Rate Swaps

The Company offers interest rate swaps to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps is classified as Level 2.

Mortgage banking derivatives

Mortgage banking derivative instruments consist of interest rate lock commitments and forward sale contracts that trade in liquid markets. The fair value is based on the prices available from third party investors. Due to the observable nature of the inputs used in deriving the fair value, the valuation of mortgage banking derivatives are classified as Level 2.

47

Impaired Loans

The fair values of impaired loans are generally measured for impairment using the practical expedients permitted by FASB ASC 310-10-35 including impaired loans measured at an observable market price (if available), or at the fair value of the loan’s collateral (if the loan is collateral dependent). Fair value of the loan’s collateral, when the loan is dependent on collateral, is determined by appraisals or independent valuation, less costs to sell of 8.5%. For commercial and industrial and asset backed loans, independent valuations may be comprised of a 20-60% discount for eligible accounts receivable and a 50-70% discount for inventory. These result in a Level 3 classification.

OREO

OREO is fair valued at the time the loan is foreclosed upon and the asset is transferred to OREO. The value is based primarily on third party appraisals, less costs to sell of 8.5% and result in a Level 3 classification of the inputs for determining fair value. OREO is reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted to lower of cost or market accordingly, based on the same factors identified above.

Loans held for sale

Loans held for sale are carried at the lower of cost or fair value, as determined by outstanding commitments from investors, or based on recent comparable sales (Level 2 inputs), if available, and if not available, are based on discounted cash flows using current market rates applied to the estimated life and credit risk (Level 3 inputs) or may be assessed based upon the fair value of the collateral, which is obtained from recent real estate appraisals (Level 3 inputs). These appraisals may utilize a single valuation approach or a combination of approaches including the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in Level 3 classification of the inputs for determining fair value.

During the first quarter of 2018, the Company adopted ASU 2016-01, “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” Among other things, the guidance requires the Company to base their fair value disclosures for financial instruments that are not measured at fair value in the financial statements on the exit price notion as opposed to an entry pricing notion. As of December 31, 2017, the Company used the entry prices to measure the fair value of certain assets and liabilities including loans, deposits, and subordinated debentures as permitted by ASC 820-10. However, upon adoption of ASU 2016-01, the Company began measuring these assets and liabilities based on the exit price notion. Although the exit price notion represents the value that would be received to sell an asset or paid to transfer a liability, the actual price received for a sale of assets or paid to transfer liabilities could be different from exit price disclosed.

The methods and assumptions used to estimate fair value are described as follows:

The carrying amount is the estimated fair value for cash and cash equivalents, savings and other interest bearing demand deposits, customer’s and Bank’s liabilities on acceptances, noninterest bearing deposits, short-term debt, secured borrowings and variable rate loans or deposits that reprice frequently and fully. For loans the fair value is determined through a discounted cash flow analysis which incorporates probability of default and loss given default rates on an individual loan basis. The discount rate is based on the LIBOR Swap Rate for fixed rate loans, while variable loans start with the corresponding index rate and an adjustment was made on certain loans which considered factors such as servicing costs, capital charges, duration, asset type incremental costs, and use of projected cash flows. Residential real estate loans fair values included Fannie Mae and Freddie Mac prepayment speed assumptions or a third party index based on historical prepayment speeds. Fair value of time deposits is based discounted cash flow analysis using recent issuance rates over the prior three months and a market rate analysis of recent offering rates for retail products. Wholesale time deposits fair values incorporated brokered time deposit offering rates. The fair value of the Company’s debt is based on current rates for similar financing. Fair value for the Company’s convertible notes is based on the actual last traded price of the notes. It was not practicable to determine the fair value of FRB stock or FHLB stock due to restrictions placed on their transferability. The fair value of commitments to fund loans represents fees currently charged to enter into similar agreements with similar remaining maturities and is not presented herein. The fair value of these financial instruments is not material to the consolidated financial statements.

16.    Stockholders’ Equity

Total stockholders’ equity at June 30, 2018 was $1.91 billion, compared to $1.93 billion at December 31, 2017.

The Company assumed certain warrants (related to the TARP Capital Purchase Plan) to purchase shares of the Company’s common stock. On May 20, 2015, the U.S. Treasury Department completed an auction to sell certain warrant positions, and the Company submitted the winning bid to repurchase an outstanding warrant to purchase 350,767 shares of the Company’s common stock. The Company repurchased this warrant for $1.2 million. As of June 30, 2018, the U.S. Treasury Department held one remaining warrant for the purchase of 20,673 shares of the Company’s common stock.

During the second quarter of 2018, the Company recorded $21.4 million in additional paid-in capital from the convertible notes issued. The $21.4 million included $21.9 million for the equity component of the convertible notes offset by $461 thousand in issuance costs from the convertible notes that was allocated to equity. The Company also recorded a tax adjustment on the equity component of the convertible notes reducing additional paid-in capital by $6.4 million.

On April 26, 2018, the Company’s Board of Directors approved a share repurchase program that authorized the Company to repurchase up to $100.0 million in common stock. During the second quarter of 2018, the Company repurchased 4.4 million shares of common stock which was recorded as treasury stock totaling $79.0 million. This led to a decline in stockholders’ equity at June 30, 2018 compared to December 31, 2017.

The Company paid a quarterly dividend of $0.13 per common share for the second quarter of 2018 compared to $0.12 per common share for the second quarter of 2017. For the six months ended June 30, 2018 and 2017, the Company paid total dividends of $0.26 and $0.24 per common share, respectively.

The following table presents the quarterly changes to accumulated other comprehensive (loss) income for the three and six months ended June 30, 2018 and June 30, 2017:

Reclassification to retained earnings per ASU 2016-01	281			—
Balance at end of period	$	(45,122	)	$	(10,089	)

During the first quarter of 2018, the Company adopted ASU 2016-01 “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” As a result of the adoption of ASU 2016-01, the Company no longer accounts for mutual funds as available-for-sale securities and accounts for these investments as equity investments with changes to fair value recorded through earnings. In accordance with ASU 2016-01, the Company reclassified $281 thousand in net unrealized losses included in other comprehensive income, net of taxes, at December 31, 2017 to retained earnings on January 1, 2018. For the three and six months ended and June 30, 2018 and 2017, there were no other reclassifications out of accumulated other comprehensive (loss) income.

17.    Regulatory Matters

The Company and the Bank are subject to various regulatory capital requirements administered by the federal and state 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 material and adverse effect on the Company’s and the Bank’s business, financial condition and results of operation, such as restrictions on growth or the payment of dividends or other capital distributions or management fees. 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 their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

In July, 2013, the federal bank regulatory agencies adopted final regulations, which revised their risk-based and leverage capital requirements for banking organizations to meet requirements of Dodd-Frank and to implement Basel III international agreements reached by the Basel Committee. The final rules began for the Company and the Bank on January 1, 2015 and are subject to a phase-in period through January 1, 2019. The final rules that had an impact on the Company and the Bank include:

• An increase in the minimum Tier 1 capital ratio from 4.00% to 6.00% of risk-weighted assets;

• A new category and a required 4.50% of risk-weighted assets ratio is established for “Common Equity Tier 1” as a subset of Tier 1 capital limited to common equity;

• A minimum non-risk-based leverage ratio is set at 4.00%, eliminating a 3.00% exception for higher rated banks;

• Changes in the permitted composition of Tier 1 capital to exclude trust preferred securities, mortgage servicing rights and certain deferred tax assets and include unrealized gains and losses on available for sale debt and equity securities;

• The risk-weights of certain assets for purposes of calculating the risk-based capital ratios are changed for high volatility commercial real estate acquisition, development and construction loans, certain past due non-residential mortgage loans and certain mortgage-backed and other securities exposures; and

• A new additional capital conservation buffer of 2.5% of risk weighted assets over each of the required capital ratios is being phased in from 2016 to 2019 and must be met to avoid limitations on the ability of the Bank to pay dividends, repurchase shares, or pay discretionary bonuses. The capital conservation buffer for the Company was initially 0.625% in 2016, and increases 0.625% annually until 2019. As ofJune 30, 2018, the capital conservation buffer for the Company stood at 1.875%.

As of June 30, 2018, the ratios for the Company and the Bank were sufficient to meet the fully phased-in conservation buffer.

As of June 30, 2018 and December 31, 2017, the most recent regulatory notification categorized the Bank as “well-capitalized” under the regulatory framework for prompt corrective action. To generally be categorized as “well-capitalized”, the Bank must maintain minimum total risk-based, Tier I risk-based, common equity Tier 1, and Tier I leverage ratios as set forth in the following table. There are no conditions or events since the most recent notification from regulators that management believes has changed the institution’s category.

18.    Revenue Recognition

On January 1, 2018, the Company adopted ASU No. 2014-09 “Revenue from Contracts with Customers” (Topic 606) and all subsequent issued ASUs that are related to Topic 606. The implementation of the new standard did not have a material impact on the measurement or recognition of revenue; as such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period results were not adjusted and continue to be reported in accordance with previous accounting guidance under Topic 605.

Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also out of scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as deposit related fees, wire transfer fees, and OREO related net gains or expenses. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Noninterest revenue streams in-scope of Topic 606 are discussed below.

Service Charges on Deposit Accounts and Wire Transfer Fees

Service charges on noninterest and interest bearing deposit accounts consist of monthly service charges, customer analysis charges, non-sufficient funds (“NSF”) charges, other deposit account related charges, and wire transfer fees. The Company’s performance obligation for account analysis charges and monthly service charges is generally satisfied, and the related revenue recognized, over the period in which the service is provided. NSF charges and other deposit account related charges are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts.

Service charges on deposit accounts and wire transfers are summarized below:

	Three Months Ended June 30,				Six Months Ended June 30
	2018		2017		2018		2017
	(Dollars in thousands)
Noninterest bearing deposit account income:
Monthly service charges	$	446	$	444	$	885	$	908
Customer analysis charges	2,036		2,164		4,060		4,344
NSF charges	1,895		2,320		3,986		4,734
Other service charges	221		235		454		498
Total noninterest bearing deposit account income	4,598		5,163		9,385		10,484
Interest bearing deposit account income:
Monthly service charges	15		16		29		33
Total service fees on deposit accounts	$	4,613	$	5,179	$	9,414	$	10,517
Wire transfer fees income:
Wire transfer fees	$	1,149	$	1,229	$	2,229	$	2,330
Foreign exchange fees	101		114		228		199
Total wire transfer fees	$	1,250	$	1,343	$	2,457	$	2,529

OREO Income (Expense)

OREO is often sold in a transaction that, under ASU 2014-09, may not be considered a contract with a customer because the sale of the asset may not be an output of the Company’s ordinary activities. However, sales of nonfinancial assets, including in-substance nonfinancial assets, should be accounted for in accordance with ASC Subtopic 610-20, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets”, which requires the Company to apply certain measurement and recognition concepts of ASC 606. Accordingly, the Company recognizes the sale of a real estate property, along with any associated gain or loss, when control of the property transfers to the buyer. For sales of existing real estate properties, this generally will occur at a point in time. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. Application of the new revenue recognition standard does not materially change the amount and the timing of the gain/loss on sale of OREO and other nonfinancial assets. Further, there were no open OREO/nonfinancial assets sale contracts at the adoption date that required an evaluation under Topic 606. The Company recognized a gain on sale of OREO of $79 thousand and $86 thousand for the three months ended June 30, 2018 and 2017, respectively. For the six months ended June 30, 2018 and 2017, the Company recognized a gain on sale of OREO of $151 thousand and $82 thousand, respectively.

Results of Operations

Overview

Total assets increased $663.3 million from $14.21 billion at December 31, 2017 to $14.87 billion at June 30, 2018. The increase in total assets was primarily due to an increase in net loans receivable of $563.5 million and an increase in securities available for sale of $114.8 million during the six months ended June 30, 2018. The increase in assets from December 31, 2017 to June 30, 2018 was funded by an increase in deposits and net funds received from the convertible note issuance partly offset by the repayment of FHLB advances.

Net income for the second quarter of 2018 was $47.5 million, or $0.36 per diluted common share, compared to $40.7 million, or $0.30 per diluted common share, for the same period of 2017, which was an increase of $6.8 million, or 16.8%. The increase in net income was mostly due to the increase in interest income from the increase in the volume and rate on loans receivable for the second quarter of 2018 compared to the second quarter of 2017 partially offset by an increase in interest expense due to the increase in volume and rates on deposits for the same period. Net interest income before provision for loan losses increased $6.0 million in the second quarter of 2018 to $122.8 million compared to $116.8 million in the second quarter of 2017.

Net income for the six months endedJune 30, 2018 was $98.8 million, or $0.73 per diluted common share, compared to $76.9 million, or $0.57 per diluted common share, for the same period of 2017, which represents an increase of $21.9 million , or 28.4%. The increase in net income was largely due to the increase in interest income from the increase on loans receivable for the six months ended June 30, 2018 compared to the same period in the prior year partially offset by an increase in interest expense.

Net income also increased for the three and six months ended June 30, 2018 compared to the same periods in 2017 due in part to the impact of the Tax Act which lowered the corporate tax rate from 35% to 21% starting January 1, 2018.

The following table summarizes the accretion and amortization adjustments resulting from prior acquisitions that are included in net income for the three and six months ended June 30, 2018 and 2017:

The annualized return on average assets was 1.30% for the second quarter of 2018 compared to 1.21% for the same period of 2017. The annualized return on average stockholders’ equity was 9.89% for the second quarter of 2018 compared to 8.60% for the same period of 2017. The efficiency ratio was 51.87% for the second quarter of 2018 compared to 48.17% for the same period of 2017.

The annualized return on average assets was 1.37% for the six months endedJune 30, 2018 compared to 1.15% for the same period of 2017. The annualized return on average stockholders’ equity was 10.25% for the six months endedJune 30, 2018 compared to 8.18% for the same period of 2017. The efficiency ratio was 50.39% for the six months endedJune 30, 2018 compared to 49.63% for the same period of 2017.

Net Interest Income and Net Interest Margin

Net Interest Income

A principal component of our earnings is net interest income, which is the difference between the interest and fees earned on loans and investments and the interest paid on deposits, borrowed funds, and convertible notes. Net interest income expressed as a percentage of average interest earning assets is referred to as the net interest margin. The net interest spread is the yield on average interest earning assets less the cost of average interest bearing liabilities. Net interest income is affected by changes in the balances of interest earning assets and interest bearing liabilities and changes in the yields earned on interest earning assets and the rates paid on interest bearing liabilities.

Comparison of Three Months Ended June 30, 2018 with the Three Months Ended June 30, 2017

Net interest income before provision for loan losses was $122.8 million for the second quarter of 2018 compared to $116.8 million for the same period of 2017, an increase of $6.0 million, or 5.1%. The increase in net interest income was due largely to the increase in loans offset by an increase in deposits for the second quarter of 2018 compared to the second quarter of 2017. The increase in rates in 2017 and 2018 also contributed to the increase in net interest income as a result of the increase in loan yields partially offset by an increase in deposit costs.

Interest income for the second quarter of 2018 was $159.9 million, an increase of $21.4 million, or 15.4%, compared to $138.5 million for the same period of 2017. The increase in interest income was primarily attributable to the increase in loans as result of higher originations as well as an increase in loan rates.

Interest expense for the second quarter of 2018 was $37.1 million, an increase of $15.4 million, or 70.8%, compared to $21.7 million for the same period of 2017. The increase in interest expense was primarily due to the increase in overall deposits, the rise in interest rates, and the addition of interest expense on convertible notes.

Comparison of Six Months Ended June 30, 2018 with the Six Months Ended June 30, 2017

Net interest income before provision for loan losses was $242.9 million for the six months ended June 30, 2018 compared to $231.7 million for the same period of 2017, an increase of $11.2 million, or 4.8%. The increase in interest income was primarily attributable to the increase in loans as result of higher originations as well as an increase in loan rates.

Interest income for the six months ended June 30, 2018 was $310.3 million, an increase of $39.0 million, or 14.4%, compared to $271.3 million for the same period of 2017. The increase in interest income was primarily attributable to the increase in loans as result of higher originations as well as an increase in loan rates.

Interest expense for the six months ended June 30, 2018 was $67.4 million, an increase of $27.9 million, or 70.5%, compared to $39.6 million for the same period of 2017. The increase in interest expense was primarily due to the increase in overall deposits, the rise in interest rates, and the addition of interest expense on convertible notes.

Net Interest Margin

Our net interest margin is impacted by the weighted average rates we earn on interest earning assets and pay on interest bearing liabilities and the effect of acquisition accounting adjustments. The net interest margin for the second quarter of 2018 was 3.61%, a decrease of 14 basis points from 3.75% for the same period of 2017. Net interest margin for the six months ended June 30, 2018 was 3.64%, a decrease of 12 basis points from 3.76% for the same period of 2017.

The weighted average yield on loans increased to 5.16% for the second quarter of 2018 from 4.89% for the second quarter of 2017. The weighted average yield on loans increased to 5.10% for the six months ended June 30, 2018 compared to 4.85% for the six months ended June 30, 2017. The change in loan yields for the three and six months ended June 30, 2018 compared to the same periods in 2017 was mostly due to the increase in overall interest rates experienced in 2017 and 2018. The Federal Open Market Committee raised interest rates during the fourth quarter of 2017 and again in the first two quarters of 2018. The increase in interest rates led to an increase in rates on our variable rate loans and new loans were originated at higher rates which resulted in an increase in loan yields. At June 30, 2018 and 2017, variable interest rate loans made up 45% of the loan portfolio and the remaining 55% of the loan portfolio consisted of loans with fixed rate interest rates. For the three and six months ended June 30, 2018, the average weighted rate on new loan originations was 4.79% and 4.72%, respectively, compared to 4.56% and 4.43% for the three and six months ended June 30, 2017, respectively.

Discount accretion income on acquired loans also increased to $9.1 million and $18.1 million for the three and six months ended June 30, 2018, respectively, compared to $8.7 million and $16.7 million for the three and six months ended June 30, 2017, respectively.

The weighted average yield on securities available for sale for the second quarter of 2018 was 2.52% compared to 2.18% for the same period of 2017. The weighted average yield on securities available for sale for the six months ended June 30, 2018 was 2.49% compared to 2.14% for the same period of 2017. The increase in weighted average yield on securities available for sale for the three and six months ended June 30, 2018 compared to the same periods of 2017 was due to the purchase of investment securities with higher yields during the six months ended June 30, 2018.

The weighted average yield on FHLB stock and other investments for the second quarter of 2018 was 2.02% compared to 1.40% for the same period of 2017. The weighted average yield on FHLB stock and other investments for the six months ended June 30, 2018 was 1.94% compared to 1.34% for the same period of 2017. The increase in weighted average yield on FHLB stock and other investments for three and six months ended June 30, 2018 compared to the same periods of 2017 was due to the increase in interest rates experienced during the twelve months ended June 30, 2018.

The weighted average cost of deposits for the second quarter of 2018 was 1.06%, an increase of 38 basis points from 0.68% for the same period of 2017. The weighted average cost of deposits for the six months ended June 30, 2018 was 0.99%, an increase of 37 basis points from 0.62% for the six months ended June 30, 2017. The premiums recorded for time and savings deposits acquired from Wilshire were fully amortized at the end of April 2017. The reduction in Wilshire premium amortizations in addition to the increase in interest rates in 2017 and 2018, resulted in an increase in the weighted average cost of deposits for the three and six months ended June 30, 2018 compared to the same periods of 2017.

The weighted average cost of FHLB advances for the second quarter of 2018 was 1.75%, an increase of 44 basis points from 1.31% for the same period of 2017. The weighted average cost of FHLB advances for the six months ended June 30, 2018 was 1.72%, an increase of 41 basis points from 1.31% for the same period of 2017. The increase in weighted average cost of FHLB advances was due to the increase in interest rates, as well as the overall longer average weighted maturity of advances at June 30, 2018 compared to June 30, 2017.

The weighted average cost of other borrowings or subordinated debentures for the second quarter of 2018 was 6.51%, an increase of 133 basis points from 5.18% for the same period of 2017. The weighted average cost of other borrowings for the six months ended June 30, 2018 was 6.19%, an increase of 112 basis points from 5.07%. Subordinated debenture rates are based of three month LIBOR rates, which have increased over 100 basis points since June 30, 2017, thus resulting in increased rates for our subordinated debentures for the three and six months ended June 30, 2018 compared to the same periods in 2017.

During the second quarter of 2018 we issued $217.5 million in convertible notes. The carrying balance of our convertible notes are net of discount and issuance costs to be capitalized. The weighted average cost of our convertible notes was 4.60% for the three and six months ended June 30, 2018. We had no convertible notes outstanding during the three and six months ended June 30, 2017. The convertible notes cost consists of the coupon rate, non-cash conversion option rate and issuance cost capitalization rate. After the fifth year, the cost of the convertible notes will decline as the non-cash conversion discount will be fully amortized and the issuance costs will be fully capitalized leaving the 2.00% coupon as the only cost.

Provision for Loan Losses

The provision for loan losses reflects our judgment of the current period cost associated with credit risk inherent in our loan portfolio. The loan loss provision for each period is dependent upon many factors, including loan growth, net charge offs, changes in the composition of the loan portfolio, delinquencies, assessments by management, third parties’ and regulators’ examination of the loan portfolio, the value of the underlying collateral on problem loans and the general economic conditions in our market areas. Specifically, the provision for loan losses represents the amount charged against current period earnings to achieve an allowance for loan losses that, in our judgment, is adequate to absorb probable incurred losses inherent in our loan portfolio. Periodic fluctuations in the provision for loan losses result from management’s assessment of the adequacy of the allowance for loan losses; however, actual loan losses may vary in material respects from current estimates. If the allowance for loan losses is inadequate, we may be required to record additional loan loss provision, which may have a material adverse effect on our business, financial condition, and results of operations.

The provision for loan losses for the second quarter of 2018 was $2.3 million, a decrease of $460 thousand from $2.8 million for the same period last year. The provision for loan losses for the six months ended June 30, 2018 was $4.8 million, a decrease of $3.6 million from $8.4 million for the six months ended June 30, 2017. The decrease in provision for loan losses for periods in 2018 compared to the same periods in 2017 was due to a decline in net charge offs facilitated by an increase in loan recoveries. The continuing decline in net charge offs has led to a reduction in loss rate on non-impaired loans reducing the required provision for loan losses for periods in 2018 compared to periods in 2017.

See Financial Condition section of this MD&A for additional information and further discussion.

Noninterest Income

Noninterest income is primarily comprised of service fees on deposit accounts, fees received on trade finance letters of credit, loan servicing fees, wire transfer fees, net gains on sales of loans, and other income which includes changes in the fair value of our equity investments with readily determinable fair value. Noninterest income for the second quarter of 2018 was $15.3 million compared to $16.1 million for the same quarter of 2017, a decrease of $846 thousand, or 5.2%. Noninterest income for the six months ended June 30, 2018 was $35.1 million compared to $33.7 million for the six months ended June 30, 2017, an increase of $1.4 million, or 4.2%.

Loan servicing fees, net	2,589		2,729		(140		)	(5.1	)%
Wire transfer fees	2,457		2,529		(72		)	(2.8	)%
Net gains on sales of SBA loans	6,930		6,517		413			6.3	%
Net gains on sales of other loans	1,627		772		855			110.8	%
Other income and fees	9,870		8,427		1,443			17.1	%
Total noninterest income	$	35,119	$	33,718	$	1,401		4.2	%

The decrease in noninterest income for the second quarter of 2018 compared to the second quarter of 2017 was largely due to a decrease in service fees on deposits accounts, loan servicing fee income and a decrease in other income and fees partially offset by an increase in gain on sale of SBA and other loans. The increase in noninterest income for the six months ended June 30, 2018 compared to the six months ended June 30, 2017 was largely due to an increase in other income and fees and net gain on sale of other loans offset by a decline in service fees on deposit accounts.

The decrease in service fees on deposit accounts for the three and six months ended June 30, 2018 compared the same periods of 2017 was due to a decline in non-sufficient fee charges and business analysis fees. We continue to experience a decline in non-sufficient fee charges as the number of customer overdrafts have continued to decline. During the twelve months ended June 30, 2018 we focused less on attracting deposit customers with increased risk profiles such as check cashing businesses and money service businesses, which has resulted in a decline in the number of these demand deposit accounts and the associated business analysis fees earned from these accounts.

During the three months ended June 30, 2018 we sold $52.5 million in SBA loans and $12.4 million in residential mortgage loans compared to $46.1 million in SBA loans sold and $18.5 million residential mortgage loans sold during the three months ended June 30, 2017. For the six months ended June 30, 2018 we sold $101.1 million in SBA loans and $58.3 million in residential mortgage loans compared to $91.0 million in SBA loans sold and $40.1 million in residential mortgage loans sold during the six months ended June 30, 2017.

During the first quarter of 2018 we adopted ASU 2016-01, which requires changes in the fair value of certain equity investments to be recorded in earnings. As a result of the adoption of ASU 2016-01 we recorded $3.5 million in other income and fees during the six months ended June 30, 2018 to account for the change in fair value of our mutual funds and equity stock owned. This increase, partially offset by a decline in swap fee income, led to an increase in other income and fees for the six months ended June 30, 2018 compared to the same period of the prior year.

Noninterest Expense

Noninterest expense for the second quarter of 2018 was $71.6 million, an increase of $7.6 million, or 11.9%, from $64.0 million for the same period of 2017. Noninterest expense for the six months ended June 30, 2018 was $140.1 million, an increase of $8.3 million, or 6.3%, from $131.7 million for the six months ended June 30, 2017.

The increase in noninterest expense for the three and six months ended June 30, 2018 compared to the three and six months ended June 30, 2017 was mostly due to an increase in salaries and employee benefits partially offset by a decline in OREO related expenses, merger and integration expenses, and other noninterest expenses.

Salaries and employee benefits expense increased $5.6 million for the second quarter of 2018 compared to the same period in 2017 and increased $10.8 million for the six months ended June 30, 2018 compared to the same period of in 2017. The increase in salaries and employee benefits expense for the three and six months ended June 30, 2018 compared to the three and six months ended June 30, 2017 was largely due to an increase in the number of full-time equivalent employees. The number of full-time equivalent employees increased from 1,378 at June 30, 2017 to 1,491 at June 30, 2018. During the twelve months ended June 30, 2018, we made significant investments in our risk, compliance, SOX, and accounting departments due to the increased compliance requirements of a larger institution and to prepare for additional growth. We also hired additional staff in our commercial and residential lending departments as we continue to expand these lines of businesses.

69

Advertising and marketing expense experienced an increase of $343 thousand for the second quarter of 2018 compared to the second quarter of 2017 due to an increase in advertising related to our deposit campaign and east coast branch locations during the second quarter of 2018. For the six months ended June 30, 2018, advertising and marketing expense decreased by $782 thousand compared to the same period in the prior year as 2017 included $1.5 million in sponsorship fees paid to sponsor the Ladies Professional Golf Association Bank of Hope Founders Cup event in March 2017 for the first time. Subsequent to the initial sponsorship, we now accrue for this annual expense, which resulted in a reduction in advertising and marketing expenses for periods in 2018 compared to 2017.

Data processing and communications fees increased for the three and six months ended June 30, 2018 compared to the three and six months ended June 30, 2017 due to the increased number of deposit and loan accounts for the periods in 2018 compared to the prior year periods. The increase in deposit and loan accounts led to an increase in the number of transactions, which resulted in higher data processing fees paid for periods in 2018 compared to periods in 2017.

The increase in professional fees for the three and six months ended June 30, 2018 compared to the three and six months ended June 30, 2017 was due to an increase in consulting fees for the periods in 2018 compared to the same periods in 2017. The new compliance requirements as a result of exceeding $10 billion in total assets has resulted in additional spending to improve upon our infrastructure in fields related to IT, accounting, and risk management. For the six months ended June 30, 2018 management chose to deploy a portion of the savings in tax provision that resulted from the reduction in corporate tax rate to improving certain areas of the Company with the assistance of third party consultants to prepare for becoming a larger institution.

Investments in affordable housing partnership expenses are recorded based on the financial statements of the investment projects. We make investments in affordable housing partnerships and receive Community Reinvestment Act credits and receive tax credits which reduce our overall tax provision rate. Investments in affordable housing partnership expenses are based on the performance of the underlying investment. We receive updated financial information for our investments in affordable housing partnerships and record losses based on the performance of our investments. These expenditures are offset by tax credits, which reduce our tax provision expense. Investments in affordable housing partnerships decreased from $91.3 million at June 30, 2017 to $80.8 million at June 30, 2018.

The increase in FDIC assessments for the three and six months ended June 30, 2018 compared to the three and six months ended June 30, 2017 is due to additional premiums incurred from the increase in our size as the FDIC assessment is calculated based on our average consolidated total assets minus average tangible equity.

Credit related expenses increased for the second quarter of 2018 compared to the second quarter of 2017 largely due to an increase in loan collection related expenses. Meanwhile the decrease in credit related expenses for the six months ended June 30, 2018 compared to the six months ended June 30, 2017 was due to a decline in provision for off balance sheet loan commitments.

At June 30, 2018 we had $8.7 million in recorded OREO compared to $21.8 million at June 30, 2017. The decline in OREO resulted in a reduction in OREO related expenditures as we experienced a reduction in OREO valuation expenses and expenses related to the maintenance and sale of OREO.

Other noninterest expense experienced a decline for the three and six months ended June 30, 2018 compared to the same periods of the prior year due mostly to a decrease in valuation expenses for premises held for sale. During the first quarter of 2017, we recorded a $1.1 million valuation expense on premises held for sale. We had no such recorded expenses during the six months ended June 30, 2018.

Provision for Income Taxes

Income tax provision expense was $16.6 million and $25.5 million for the quarters ended June 30, 2018 and 2017, respectively. The effective income tax rates were 25.92% and 38.48% for the quarters ended June 30, 2018 and 2017, respectively. Income tax provision expense was $34.4 million and $48.5 million for the six months ended June 30, 2018 and 2017, respectively. The effective income tax rates for the six months ended June 30, 2018 and 2017 were 25.81% and 38.65%, respectively.

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 reduced the U.S. federal corporate tax rate from 35% to 21% as of January 1, 2018. The reduction in tax rates for the three and six months ended June 30, 2018 compared to the three and six months ended June 30, 2017 reflects the reduced corporate tax rate as a result of the Tax Act in addition to an increase affordable housing partnership investment credits.

Financial Condition

At June 30, 2018, our total assets were $14.87 billion, an increase of $663.3 million, or 4.7%, from $14.21 billion at December 31, 2017. The increase in assets was due to an increase in loans receivable and investment securities available for sale.

Investment Securities Portfolio

As of June 30, 2018, we had $1.84 billion in available for sale securities compared to $1.72 billion at December 31, 2017. The net unrealized loss on the available for sale securities at June 30, 2018 was $65.1 million compared to a net unrealized loss on securities of $31.6 million at December 31, 2017.

During the six months ended June 30, 2018, $277.6 million in investment securities were purchased, $102.6 million in mortgage related securities were paid down, and $325 thousand in municipal securities were called. During the same period last year $245.2 million in investment securities were purchased, $115.4 million in mortgage related securities were paid down and we had $9.0 million in maturities. At December 31, 2017 we had $22.0 million in mutual funds that were categorized as available-for-sale. Upon the adoption of ASU 2016-01 on January 1, 2018 these investments were no longer categorized as available-for-sale securities and were reclassified as equity investments with readily determinable fair value in accordance with the adopted guidance, and changes in fair value were recorded as gains or losses in earnings.

Investments in Affordable Housing Partnerships

At June 30, 2018, we had $80.8 million in investments in affordable housing partnerships compared to $81.0 million at December 31, 2017. The decrease in investments in affordable housing partnerships was due to losses on investments in affordable housing partnerships and premium accretion recorded totaling $5.2 million during the six months ended June 30, 2018 offset by an investment of $5.0 million. Commitments to fund investments in affordable housing partnerships totaled $38.1 million at June 30, 2018 compared to $38.5 million at December 31, 2017.

Loan Portfolio

As of June 30, 2018, loans receivable totaled $11.67 billion, an increase of $568.9 million from $11.10 billion at December 31, 2017. The following table summarizes our loan portfolio by amount and percentage of total loans outstanding in each major loan category at the dates indicated:

Allowance for Loan Losses

The allowance for loan and lease losses (“ALLL”) was $89.9 million at June 30, 2018 compared to $84.5 million at December 31, 2017. The ALLL was 0.77% of loans receivable at June 30, 2018 and 0.76% of loans receivable at December 31, 2017. Total ALLL to loans receivable ratio does not include discount on acquired loans. Impaired loan reserves increased to $10.6 million at June 30, 2018 from $5.3 million at December 31, 2017.

^*  Held-for-sale loans of $26.9 million and $29.7 million at June 30, 2018 and December 31, 2017, respectively, were excluded.

For a better understanding of the changes in the ALLL, the loan portfolio has been segmented for disclosure purposes between loans which are accounted for under the amortized cost method (Legacy Loans) and loans acquired from acquisitions (Acquired Loans). Acquired Loans have been further segregated between Purchase Credit Impaired Loans (loans with credit deterioration at the time they were acquired and accounted for under ASC 310-30, or “PCI loans”) and performing loans (loans that were pass graded at the time they were acquired, or “non-PCI loans”).

* Annualized

We believe the ALLL as of June 30, 2018 was adequate to absorb probable incurred losses in the loan portfolio. However, no assurance can be given that actual losses will not exceed the estimated amounts, and if actual losses exceed the estimated amounts it could have a material and adverse effect on our financial condition and results of operations.

At June 30, 2018, we had $74.5 million in remaining discount on loans acquired from previous transactions compared to $85.8 million at December 31, 2017.

Deposits, Other Borrowings, and Convertible Notes

Deposits

Deposits are our primary source of funds used in our lending and investment activities. At June 30, 2018, deposits increased $888.0 million, or 8.2%, to $11.73 billion from $10.85 billion at December 31, 2017. The increase in deposits was primarily due to an increase in demand deposits and time deposits offset by a decline in money market and NOW and savings.

76

At June 30, 2018, 25.9% of total deposits were noninterest bearing demand deposits, 44.2% were time deposits, and 29.9% were interest bearing demand and savings deposits. At December 31, 2017, 27.7% of total deposits were noninterest bearing demand deposits, 39.4% were time deposits, and 32.9% were interest bearing demand and savings deposits.

At June 30, 2018, we had $1.20 billion in brokered deposits and $300.0 million in California State Treasurer deposits compared to $797.0 million in brokered deposits and $300.0 million in California State Treasurer deposits at December 31, 2017. The California State Treasurer deposits had six month maturities with a weighted average interest rate of 1.99% at June 30, 2018 and were collateralized with securities with a carrying value of $337.5 million. Time deposits of more than $250 thousand at June 30, 2018 totaled $1.54 billion compared to $1.28 billion at December 31, 2017.

The following is a schedule of certificates of deposit maturities as of June 30, 2018:

	Balance		Percent (%)
	(Dollars in thousands)
Three months or less	$	1,198,537	23	%
Over three months through six months	1,130,842		22	%
Over six months through nine months	1,114,197		21	%
Over nine months through twelve months	1,287,536		25	%
Over twelve months	452,830		9	%
Total time deposits	$	5,183,942	100	%

Other Borrowings

From time to time we utilize FHLB advances as a secondary source of funds. FHLB advances are typically secured by a pledge of commercial real estate loans and/or securities with a market value at least equal to the outstanding advances plus our investment in FHLB stock.

At June 30, 2018, FHLB advances totaled $837.0 million and had an average weighted remaining maturity of 2.2 years compared to $1.16 billion with an average weighted remaining maturities of 2.0 years at December 31, 2017. Total FHLB advances at June 30, 2018 included $2.0 million in premiums recorded from prior acquisitions compared to $2.7 million in FHLB advance premiums at December 31, 2017.

We did not have federal funds purchased at June 30, 2018. At December 31, 2017, we had $69.9 million in federal funds purchased, which were all fully repaid during the first quarter of 2018.

Subordinated debentures totaled $101.4 million at June 30, 2018 and $100.9 million at December 31, 2017. The Trust Preferred Securities accrue and pay distributions periodically at specified annual rates as provided in the related indentures for the securities. The trusts used the net proceeds from their respective offerings to purchase a like amount of subordinated debentures (the “Debentures”) issued by us. The Debentures are the sole assets of the trusts. Our obligations under the Debentures and related documents, taken together, constitute a full and unconditional guarantee by us of the obligations of the trusts. The Trust PreferredSecurities are mandatorily redeemable upon the maturity of the Debentures, or upon earlier redemption as provided in the indentures. We have the right to redeem the Debentures in whole (but not in part) on or after specific dates, at a redemption price specified in the indentures plus any accrued but unpaid interest to the redemption date.

Convertible Notes

During the second quarter of 2018, we issued $217.5 million aggregate principal amount of 2.00% convertible senior notes maturing on May 15, 2038 in a private offering to qualified institutional investors under Rule 144A of the Securities Act of 1933. The convertible notes were issued as part of our plan to repurchase common stock. The convertible notes pay interest on a semi-annual basis to holders of the notes. The convertible notes can be called by us at any time after five years in part or whole for the original issued amount in cash. Holders of the notes can put or redeem the notes for cash on the fifth, tenth, and fifteenth year of the note. The carrying balance of convertible notes at June 30, 2018 was $192.1 million net of a $25.4 million discount, which represents the conversion option discount and issuance costs to be capitalized. (See footnote 10 “Subordinated Debentures and Convertible Notes” for additional information regarding convertible notes issued)

Off-Balance-Sheet Activities and Contractual Obligations

We routinely engage in activities that involve, to varying degrees, elements of risk that are not reflected, in whole or in part, in the consolidated financial statements. These activities are part of our normal course of business and include traditional off-balance-sheet credit-related financial instruments, interest rate swap contracts, operating leases and long-term debt.

Traditional off-balance-sheet credit-related financial instruments are primarily commitments to extend credit and standby letters of credit. These activities could require us to make cash payments to third parties if certain specified future events occur.

77

The contractual amounts represent the extent of our exposure in these off-balance-sheet activities. These activities are necessary to meet the financing needs of our customers.

We enter into interest rate swap contracts under which we are required to either receive cash from or pay cash to counterparties depending on changes in interest rates. We also purchase interest rate caps to protect against increases in market interest rates. We utilize interest rate swap contracts and interest rate caps to help manage the risk of changing interest rates.

We sell interest rate swaps to certain adjustable rate commercial loan customers to fix the interest rate on their floating rate loans. When the fixed rate swap is originated with the customer, an identical offsetting swap is also entered into by us with a correspondent bank.

We enter into various stand-alone mortgage-banking derivatives in order to hedge the risk associated with the fluctuation of interest rates. The first type of derivative, an interest rate lock commitment, is a commitment to originate loans whereby the interest rate on the loan is determined prior to funding. To mitigate interest rate risk on these rate lock commitments we also enter into forward commitments, or commitments to deliver residential mortgage loans on a future date, also considered derivatives. Net change in the fair value of derivatives represents income recorded from changes of fair value for these mortgage derivatives instruments.

We do not anticipate that our current off-balance-sheet activities will have a material impact on our future results of operations or our financial condition. Further information regarding our financial instruments with off-balance-sheet risk can be found in Item 3 “Quantitative and Qualitative Disclosures about Market Risk.”

Stockholders’ Equity and Regulatory Capital

Historically, our primary source of capital has been the retention of earnings, net of dividend payments to stockholders. We seek to maintain capital at a level sufficient to assure our stockholders, our customers, and our regulators that we and the Bank are financially sound. For this purpose we perform ongoing assessments of our components of capital, as well as projected sources and uses of capital in conjunction with projected increases in assets and levels of risks.

Total stockholders’ equity was $1.91 billion at June 30, 2018 compared to $1.93 billion at December 31, 2017.

The federal banking agencies require a minimum ratio of qualifying total capital to risk-weighted assets of 8.0%, a minimum ratio of Tier I capital to risk-weighted assets of 6.0%, and a minimum ratio of Tier I common equity capital to risk-weighted assets of 4.5% to generally be considered “adequately capitalized” under the Prompt Corrective Action regulations. In addition to the risk-based guidelines, federal banking agencies require banking organizations to maintain a minimum amount of Tier I capital to average total assets, referred to as the leverage ratio, of 4.0% to generally be considered “adequately capitalized” under the Prompt Corrective Action regulations. Beginning January 1, 2016, federal banking agencies required a capital conservation buffer of 0.625% in addition to the ratios required to generally be considered “adequately capitalized” under the Prompt Corrective Action regulations. The capital conservation buffer increases at an annual increment of 0.625% until January 2019 and stands at 1.875% as of June 30, 2018. Failure to maintain this capital conservation buffer results in limits or prohibitions on capital distributions and discretionary compensation payments. Capital requirements apply to us and the Bank separately. In addition to these uniform risk-based capital guidelines and leverage 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.

At June 30, 2018, our common equity Tier 1 capital was $1.47 billion compared to $1.47 billion at December 31, 2017. Our Tier I capital, defined as stockholders’ equity less intangible assets and including our trust preferred securities, was $1.57 billion at June 30, 2018 and at December 31, 2017. At June 30, 2018, the common equity Tier 1 capital ratio was 11.74%. The total capital to risk-weighted assets ratio was 13.24% and the Tier I capital to risk-weighted assets ratio was 12.52%. The Tier I leverage capital ratio was 11.06%.

78

As of June 30, 2018 and December 31, 2017, the most recent regulatory notification generally categorized the Bank as “well capitalized” under the general regulatory framework for prompt corrective action. To be generally categorized as “well-capitalized” the Bank must maintain minimum common equity Tier 1 capital, total risk-based, Tier I risk-based and Tier I leverage capital ratios as set forth in the table below:

Liquidity Management

Liquidity risk is the risk of reduction in our earnings or capital that would result if we were not able to meet our obligations when they come due without incurring unacceptable losses. Liquidity risk includes the risk of unplanned decreases or changes in funding sources and changes in market conditions that affect our ability to liquidate assets quickly and with minimum loss of value. Factors considered in liquidity risk management are the stability of the deposit base; the marketability, maturity, and pledging of our investments; the availability of alternative sources of funds; and our demand for credit. The objective of our liquidity management is to have funds available to meet cash flow requirements arising from fluctuations in deposit levels and the demands of daily operations, which include funding of securities purchases, providing for customers’ credit needs, and ongoing repayment of borrowings.

Our primary sources of liquidity are derived from financing activities, which include customer and broker deposits, federal funds facilities, and borrowings from the FHLB and the FRB Discount Window. These funding sources are augmented by payments of principal and interest on loans and securities, proceeds from sale of loans and the liquidation or sale of securities from our available for sale portfolio. Primary uses of funds include withdrawal of and interest payments on deposits, originations of loans, purchases of investment securities, and payment of operating expenses.

At June 30, 2018, our total borrowing capacity from the FHLB was $3.63 billion of which $2.76 billion was unused and available to borrow. At June 30, 2018, our total borrowing capacity from the FRB was $609.1 million, all of which was unused and available to borrow. In addition to these lines, our liquid assets, consisting of cash and cash equivalents, interest bearing cash deposits and time deposits with other banks, overnight federal funds sold to other banks, liquid investment securities available for sale, and loan repayments within 30 days, were $1.85 billion at June 30, 2018 compared to $1.73 billion at December 31, 2017. Cash and cash equivalents were $466.4 million at June 30, 2018 compared to $492.0 million at December 31, 2017. We believe our liquidity sources are sufficient to meet all reasonably foreseeable short-term and intermediate-term needs.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The objective of our asset and liability management activities is to maximize our earnings while maintaining adequate liquidity and an exposure to interest rate risk deemed by management to be acceptable by adjusting the type and mix of assets and liabilities to seek to effectively address changing conditions and risks. Through overall management of our balance sheet and by seeking to manage various risks, we seek to optimize our financial returns within safe and sound parameters. Our operating strategies for attaining this objective include managing net interest margin through appropriate risk/return pricing of assets and liabilities and emphasizing growth in retail deposits, as a percentage of interest bearing liabilities, to reduce our cost of funds. We also seek to improve earnings by controlling noninterest expense, and enhancing noninterest income. We also use risk management instruments to modify interest rate characteristics of certain assets and liabilities to hedge against our exposure to interest rate fluctuations with the objective of reducing the effects fluctuations might have on associated cash flows or values. Finally, we perform internal analysis to measure, evaluate and monitor risk.

Interest Rate Risk

Interest rate risk is the most significant market risk impacting us. Interest rate risk occurs when interest rate sensitive assets and liabilities do not reprice simultaneously and in equal volume. A key objective of asset and liability management is to manage interest rate risk associated with changing asset and liability cash flows, values of our assets and liabilities, and market interest rate movements. The management of interest rate risk is governed by policies reviewed and approved annually by the Board of Directors. Our Board delegates responsibility for interest rate risk management to the Asset and Liability Committee of the Board (“ALCO”) and to the Asset and Liability Management Committee (“ALM”), which is composed of the Bank’s senior executives and other designated officers.

The fundamental objective of our ALM is to manage our exposure to interest rate fluctuations while maintaining adequate levels of liquidity and capital. Our ALM meets regularly to monitor interest rate risk, the sensitivity of our assets and liabilities to interest rate changes, the book and market values of our assets and liabilities, and our investment activities. It also directs changes in the composition of our assets and liabilities. Our strategy has been to reduce the sensitivity of our earnings to interest rate fluctuations by more closely matching the effective maturities or repricing characteristics of our assets and liabilities. Certain assets and liabilities, however, may react in different degrees to changes in market interest rates. Furthermore, interest rates on certain types of assets and liabilities may fluctuate prior to changes in market interest rates, while interest rates on other types may lag behind changes in market interest rates. We consider the anticipated effects of these factors when implementing our interest rate risk management objectives.

Interest Rate Sensitivity

We monitor interest rate risk through the use of a simulation model that provides us with the ability to simulate our net interest income. In order to measure, at June 30, 2018, the sensitivity of our forecasted net interest income to changing interest rates, both rising and falling interest rate scenarios were projected and compared to base market interest rate forecasts. One application of our simulation model measures the impact of market interest rate changes on the net present value of estimated cash flows from our assets and liabilities, defined as our market value of equity. This analysis assesses the changes in market values of interest rate sensitive financial instruments that would occur in response to immediate and parallel changes in market interest rates.

The impacts on our net interest income and market value of equity exposed to immediate and parallel hypothetical changes in market interest rates as projected by the model we use for this purpose are illustrated in the following table:

	June 30, 2018				December 31, 2017
Simulated Rate Changes	Estimated Net Interest Income Sensitivity		Market Value Of Equity Volatility		Estimated Net Interest Income Sensitivity		Market Value Of Equity Volatility
+ 200 basis points	6.43	%	(4.52	)%	2.18	%	(4.42	)%
+ 100 basis points	3.12	%	(2.19	)%	1.12	%	(2.08	)%
- 100 basis points	(3.72	)%	1.42	%	(2.22	)%	1.00	%
- 200 basis points	(9.22	)%	1.34	%	(8.56	)%	0.60	%

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are controls and procedures designed to ensure that information required to be disclosed by us in reports filed or submitted under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our President and Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

In designing and evaluating 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, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We conducted an evaluation under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based upon that evaluation, our President and Chief Executive Officer and our Chief Financial Officer determined that our disclosure controls and procedures were effective as of June 30, 2018.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during the quarter ended June 30, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

In the normal course of business, the Company is involved in various legal claims. The Company has reviewed all legal claims against us with counsel and have taken into consideration the views of such counsel as to the potential outcome of the claims in determining our accrued loss contingency. Accrued loss contingencies for all legal claims totaled approximately $420 thousand at June 30, 2018. It is reasonably possible the Company may incur losses in addition to the amounts currently accrued. However, at this time, the Company is unable to estimate the range of additional losses that are reasonably possible because of a number of factors, including the fact that certain of these litigation matters are still in their early stages and involve claims for which, at this point, the Company believes have little to no merit. Management has considered these and other possible loss contingencies and does not expect the amounts to be material to the consolidated financial statements.

Item 1A. Risk Factors

Other than the risk factors set forth below, management is not aware of any material changes to the risk factors discussed in Part 1, Item 1A, of the Annual Report on Form 10-K for the year ended December 31, 2017. In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors discussed in Part 1, Item 1A, of the Annual Report on Form 10-K for the year ended December 31, 2017, which could materially and adversely affect the Company’s business, financial condition, results of operations and stock price. The risks described in this Quarterly Report on Form 10-Q and in the Annual Report on Form 10-K are not the only risks facing the Company. Additional risks and uncertainties not presently known to management or that management presently believes not to be material may also result in material and adverse effects on our business, financial condition, and results of operations.

The conditional conversion features of the convertible note issued by the Company, if met, may adversely affect our financial condition and operating results.

In the event the conditional conversion features of the convertible notes issued by the Company are met, holders of convertible notes will be entitled to convert the notes at any time during specified periods at their option. If one or more holders elect to convert their notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity.

We may not have the ability to raise the funds necessary to settle conversions of the convertible notes in cash or to repurchase the convertible notes if holders of the convertible note exercise their repurchase rights or upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the convertible notes.

Holders of the convertible notes will have the right to require us to repurchase all or a portion of their convertible notes on certain specified dates or upon the occurrence of a fundamental change at a repurchase price equal to 100% of the principal amount of the convertible notes to be repurchased, plus accrued and unpaid special interest, if any. We may not have enough available cash or be able to obtain financing at the time we are required to repurchase convertible notes surrendered or pay cash with respect to the convertible notes being converted if we elect not to issue shares, which could harm our reputation and affect the trading price of our common stock.

Basis of Presentation

Basis of Presentation

The consolidated financial statements included herein have been prepared without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”), except for the Consolidated Statement of Financial Condition as of December 31, 2017 which was from the audited financial statements included in the Company’s 2017 Annual Report on Form 10-K. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such SEC rules and regulations.

The consolidated financial statements include the accounts of Hope Bancorp and its wholly owned subsidiaries, principally Bank of Hope. All intercompany transactions and balances have been eliminated in consolidation. The Company has made all adjustments, that in the opinion of management, are necessary to fairly present the Company’s financial position at June 30, 2018 and December 31, 2017 and the results of operations for the three and six months ended June 30, 2018 and 2017. Certain reclassifications have been made to prior period amounts to conform to the current year presentation. The results of operations for the interim periods are not necessarily indicative of results to be anticipated for the full year.

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“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 and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates.

These unaudited consolidated financial statements should be read along with the audited consolidated financial statements and accompanying notes included in the Company’s 2017 Annual Report on Form 10-K.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. Subsequently in July 2018, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842, Leases” and ASU 2018-11, “Leases Topic 842, Targeted Improvements”, to provide additional clarification, implementation, and transition guidance on certain aspects of ASU 2016-02. ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 and ASU 2018-10 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. Under ASU 2018-11, an additional transition option was provided that would allow entities to not apply the new guidance in the comparative periods they present in their financial statements in the year of adoption. Under this optional transition method, entities will be allowed to continue using and presenting leases under ASC 840 for prior years comparative periods and then prospectively adopt ASC 842 on January 1, 2019, recognizing a cumulative-effect adjustment to the opening balance of retained earnings. The Company estimated that there are approximately 100 operating leases that will be accounted for under ASU 2016-02 at the adoption date. The Company plans to elect the transition option to not reassess the following at adoption date: whether contracts are or contain leases, the lease classification for any expired or existing leases, and the evaluation of initial direct costs associated with existing leases. In July 2018, the Company engaged a new software vendor to assist the Company with the administration and accounting of leases under ASU 2016-02. The Company is currently in the process of evaluating the financial impact of the pending adoption of the new standard on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, also referred to as “CECL”. ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. ASU 2016-13 becomes effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. The Company has established a CECL committee to oversee the development and implementation of ASU 2016-13. The Company is collaborating with a third party advisory team and has completed a gap assessment, a full implementation road-map and a detailed project plan. The Company has also engaged a software vendor to assist the Company to build a model that is compliant with ASU 2016-13 by the effective date. Based on the Company’s initial assessment of the ASU 2016-13, the Company expects the new guidance will result in additional required allowance for loan losses which could potentially have a material impact on its consolidated financial statements and regulatory capital ratios.

In January 2017, the FASB issued ASU 2017-04, “Intangibles: Goodwill and Other: Simplifying the Test for Goodwill Impairment.” ASU 2017-04 will amend and simplify current goodwill impairment testing to eliminate Step 2 from the current provisions. Under the new guidance, an entity should perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. An entity still has the option to perform the quantitative assessment for a reporting unit to determine if a quantitative impairment test is necessary. ASU 2017-04 should be adopted for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of ASU 2017-04 is not expected to have a material impact on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities”. ASU 2017-08 was issued to amend the amortization period for certain callable debt securities held at a premium. ASU 2017-08 shortens the amortization period of premiums on certain purchased callable debt securities to the earliest call date. ASU 2017-08 affect all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date (that is, at a premium). ASU 2017-08 does not impact securities purchased at a discount, which continue to be amortized to maturity. ASU 2017-08 is effective for annual period beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted in an interim period. If an entity chooses to adopt early, any adjustments should be reflected as of the beginning of the fiscal year that includes the interim period. The adoption of ASU 2017-08 is not expected to have a material impact on the Company’s consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployees Share-Based Payment Accounting”. ASU 2018-07 expands the scope of Topic 718 (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services.  As ASU 2018-07 becomes effective, the accounting for share-based payments for nonemployees and employees will be substantially the same.  The ASU supersedes Subtopic 505-50, Equity – Equity-Based Payments to Non-Employees. ASU 2018-07 is effective for annual period beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted, but no earlier than a company’s adoption date of Topic 606, Revenue from Contracts with Customers.  The adoption of ASU 2018-07 is not expected to have a material impact on the Company’s consolidated financial statements as the Company has not historically issued share-based payments to nonemployees for goods and services.

Stock-Based Compensation

Stock-Based Compensation

The Company has a stock-based incentive plan (the “2016 Plan”) to award equity as a form of compensation. The 2016 Plan, was approved by the Company’s stockholders on September 1, 2016. The 2016 Plan provides for grants of stock options, stock appreciation rights (“SARs”), restricted stock, performance shares, and performance units (sometimes referred to individually or collectively as “awards”) to non-employee directors, employees, and consultants of the Company. Stock options may be either incentive stock options (“ISOs”), as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), or nonqualified stock options (“NQSOs”).

The 2016 Plan gives the Company flexibility to (i) attract and retain qualified non-employee directors, executives, other key employees, and consultants with appropriate equity-based awards to; (ii) motivate high levels of performance; (iii) recognize employee contributions to the Company’s success; and (iv) align the interests of the 2016 Plan participants with those of the Company’s stockholders. The plan initially had 2,400,000 shares available for grant to participants. The exercise price for shares under an ISO may not be less than 100% of fair market value on the date the award is granted under Code Section 422. Similarly, under the terms of the 2016 Plan, the exercise price for SARs and NQSOs may not be less than 100% of fair market value on the date of grant. Performance units are awarded to a participant at the market price of the Company’s common stock on the date of award (after the lapse of the restriction period and the attainment of the performance criteria). No minimum exercise price is prescribed for performance shares and restricted stock awarded under the 2016 Plan. All options not exercised generally expire 10 years after the date of grant.

ISOs, SARs and NQSOs have vesting periods of three to five years and have 10-year contractual terms. Restricted stock, performance shares, and performance units are granted with a restriction period of not less than one year from the grant date for performance-based awards and not more than three years from the grant date for time-based vesting of grants. Compensation expense for awards is recognized over the vesting period.

The Company had another stock-based incentive plan, the 2007 Equity Incentive Plan (“2007 Plan”), which was approved by stockholders in May 2007. Under the terms of this plan, awards cannot be granted under the plan more than ten years after the plan adoption date. Therefore, subsequent to May 2017, equity awards were not issued from this plan.

Under the 2016 Plan, 1,113,746 shares were available for future grants as of June 30, 2018.

The total shares reserved for issuance will serve as the underlying value for all equity awards under the 2016 Plan. With the exception of the shares underlying stock options and restricted stock awards, the board of directors may choose to settle the awards by paying the equivalent cash value or by delivering the appropriate number of shares.

The following is a summary of stock option activity under the 2016 Plan for the six months ended June 30,2018:

	Number of Shares		Weighted- Average Exercise Price Per Share		Weighted- Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value (Dollars in thousands)
Outstanding - January 1, 2018	1,075,423		$	15.06
Granted	—		—
Exercised	(16,742	)	11.76
Expired	(3,195	)	16.66

Outstanding - June 30, 2018	1,031,486		$	15.06	6.82	$	2,861
Options exercisable - June 30, 2018	665,380		$	13.98	6.14	$	2,564

The following is a summary of restricted stock and performance unit activity under the 2016 Plan for the six months ended June 30,2018:

	Number of Shares		Weighted- Average Grant Date Fair Value
Outstanding - January 1, 2018	379,419		$	16.42
Granted	266,225		16.23
Vested	(63,105	)	15.51
Forfeited	(17,556	)	16.12
Outstanding - June 30, 2018	564,983		$	16.50

The total fair value of restricted stock and performance units vested for the six months ended June 30, 2018 and 2017 was $1.2 million and $1.3 million, respectively.

On August, 21, 2017 the Company adopted the Hope Employee Stock Purchase Plan (“ESPP”). The ESPP allows eligible employees to purchase the Company’s common shares through payroll deductions which build up between the offering date and the purchase date. At the purchase date, the Company uses the accumulated funds to purchase shares in the Company on behalf of the participating employees at a 10% discount to the closing price of the Company’s common shares. The closing price is the lower of either the closing price on the first day of the offering period or on the closing price on the purchase date. The dollar amount of common shares purchased under the ESPP must not exceed 20% of the participating employee’s base salary, subject to a cap of $25 thousand in stock value based on the grant date. The ESPP is considered compensatory under GAAP and compensation expense for the ESPP is recognized as part of the Company’s stock based compensation expenses. The compensation expense for ESPP during the six months ended June 30, 2018 and 2017 was $148 thousand and $0, respectively.

The amount charged against income related to stock-based payment arrangements, including ESPP, was $915 thousand and $760 thousand for the three months ended June 30, 2018 and 2017, respectively. For the six months ended June 30, 2018 and 2017, $1.9 million and $1.5 million, respectively, of stock-based payment arrangements were charged against income. The income tax benefit recognized was approximately $237 thousand and $292 thousand for the three months ended June 30, 2018 and 2017, respectively. The income tax benefit recognized for the six months ended June 30, 2018 and 2017, was approximately $482 thousand and $582 thousand, respectively.

At June 30, 2018, the unrecognized compensation expense related to non-vested stock option grants was $669 thousand which is expected to be recognized over a weighted average vesting period of 2.72 years. Unrecognized compensation expense related to non-vested restricted stock and performance units was $6.1 million which is expected to be recognized over a weighted average vesting period of 2.70 years.

Earnings Per Share ("EPS")

Earnings Per Share [Abstract]

Earnings Per Share ("EPS")

Earnings Per Share (“EPS”)

Basic EPS does not reflect the possibility of dilution that could result from the issuance of additional shares of common stock upon exercise or conversion of outstanding equity awards or convertible notes, and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if stock options or other contracts to issue common stock were exercised or converted to common stock that would then share in earnings. For the three months ended June 30, 2018 and 2017, stock options and restricted shares awards for 306,136 and 530,334 shares of common stock, respectively, were excluded in computing diluted earnings per common share because they were anti-dilutive. For the six months ended June 30, 2018 and 2017, stock options and restricted shares awards for 303,338 and 542,328 shares of common stock, respectively, were excluded in computing diluted earnings per common share because they were anti-dilutive. Additionally, warrants issued pursuant to the Company’s participation in the U.S. Treasury’s TARP Capital Purchase Plan, to purchase 20,673 shares and 20,087 shares of common stock were anti-dilutive and excluded for the three and six months ended June 30, 2018 and 2017, respectively.

During the second quarter of 2018, the Company issued $217.5 million in convertible notes. The convertible notes can be converted to the Company’s shares of common stock at an initial rate of 45.0760 shares per $1,000 principal amount of the notes (See footnote 10 “Subordinated Debentures and Convertible Notes” for additional information regarding convertible notes issued). For the three and six months ended June 30, 2018, shares related to the convertible notes issued were not included in the Company’s diluted EPS calculation. In accordance with the terms of the convertible notes and settlement options available to the Company, no shares would have been delivered to investors of the convertible notes upon assumed conversion based on the Company’s common stock price during the three and six months ended June 30, 2018.

On April 26, 2018, the Company’s Board of Directors approved a share repurchase program that authorized the Company to repurchase up to $100.0 million in common stock. During the second quarter of 2018, the Company repurchased 4.4 million shares of common stock totaling $79.0 million which were recorded as treasury stock and these shares were excluded from weighted average shares and weighted average diluted shares for the three and six months ended June 30, 2018 after they were repurchased.

As of June 30, 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.

At June 30, 2018 and December 31, 2017, $46.2 million and $19.0 million, respectively, in unrealized losses on securities available for sale net of taxes were included in accumulated other comprehensive loss. Also included in accumulated other comprehensive loss at June 30, 2018 and December 31, 2017, were unrealized losses on interest only strip net of taxes of $47 thousand and $41 thousand, respectively. There were no reclassifications out of accumulated other comprehensive loss into earnings during the three and six months ended June 30, 2018 or 2017.

On January 1, 2018, the Company adopted ASU 2016-01 “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities”. As a result of the adoption of ASU 2016-01, the Company no longer accounts for mutual funds as available-for-sale securities and accounts for these investments as equity investments with readily determinable fair value with changes in fair value recorded through earnings. In accordance with ASU 2016-01, the Company reclassified $469 thousand in net unrealized losses included in other comprehensive income and deferred tax assets as of December 31, 2017 to retained earnings on January 1, 2018. The subsequent changes to fair value for mutual funds were recorded as other noninterest income for the three and six months ended June 30, 2018.

The amortized cost and estimated fair value of investment securities at June 30, 2018, by contractual maturity, is presented in the table below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.

* Investments in U.S. Government agency and U.S. Government sponsored enterprises

The Company evaluates securities for other-than-temporary-impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to the financial condition and near-term prospects of the issuer, the length of time and the extent to which the fair values of the securities have been less than the cost of the securities, and management’s intention to sell, or whether it is more likely than not that management will be required to sell the security in an unrealized loss position before recovery of its amortized cost basis. In analyzing an issuer’s financial condition, the Company considers, among other considerations, whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition.

The Company had collateralized mortgage obligations, mortgage backed securities, and municipal securities that were in a continuous unrealized loss position for twelve months or longer as of June 30, 2018. The collateralized mortgage obligations in a continuous loss position for twelve months or longer had unrealized losses of $19.0 million at June 30, 2018 and total mortgage backed securities in a continuous loss position for twelve months or longer had total unrealized losses of $18.8 million. These securities were issued by U.S. Government agency and U.S. Government sponsored enterprises and have high credit ratings of “AA” grade or better. Interest on U.S. Government agency and U.S. Government sponsored enterprise investments have been paid as agreed, and management believes this will continue in the future and that the securities will be repaid in full as scheduled. Municipal securities that were in a continuous loss position for twelve months or longer had unrealized losses of $1.6 million at June 30, 2018. The market value declines for these securities were primarily due to movements in interest rates and are not reflective of management’s expectations of the Company’s ability to fully recover these investments, which may be at maturity. For these reasons, no OTTI was recognized on U.S. Government sponsored collateralized mortgage obligations and mortgage backed securities, and municipal securities that were in an unrealized loss position at June 30, 2018.

The Company considers the losses on the investments in unrealized loss positions at June 30, 2018 to be temporary based on: 1) the likelihood of recovery; 2) the information relative to the extent and duration of the decline in market value; and 3) the Company’s intention not to sell, and management’s determination that it is more likely than not that the Company will not be required to sell a security in an unrealized loss position before recovery of its amortized cost basis.

Loans Receivable and Allowance for Loan Losses

Loans Receivable and Allowance for Loan Losses

The following is a summary of loans receivable by major category:

	June 30, 2018			December 31, 2017
	(Dollars in thousands)
Loan portfolio composition
Real estate loans:
Residential	$	45,383		$	49,774
Commercial	8,165,420			8,142,036
Construction	301,937			316,412
Total real estate loans	8,512,740			8,508,222
Commercial business	2,131,301			1,780,869
Trade finance	156,181			166,664
Consumer and other	872,562			647,102
Total loans outstanding	11,672,784			11,102,857
Deferred loan fees, net	(1,344		)	(282		)
Loans receivable	11,671,440			11,102,575
Allowance for loan losses	(89,881		)	(84,541		)
Loans receivable, net of allowance for loan losses	$	11,581,559		$	11,018,034

The loan portfolio is made up of four segments: real estate loans, commercial business, trade finance, and consumer and other. These segments are further segregated between loans accounted for under the amortized cost method (“Legacy Loans”) and previously acquired loans that were originally recorded at fair value with no carryover of the related pre-acquisition allowance for loan losses (“Acquired Loans”). Acquired Loans are further segregated between purchased credit impaired loans (loans with credit deterioration on the acquisition date and accounted for under ASC 310-30, or “PCI loans”) and Acquired Performing Loans (loans that were pass graded on the acquisition date and the fair value adjustment is amortized over the contractual life under ASC 310-20, or “non-PCI loans”).

The following table presents changes in the accretable discount on the PCI loans for the three and six months ended June 30, 2018 and 2017:

	Three Months Ended June 30,						Six Months Ended June 30,
	2018			2017			2018			2017
	(Dollars in thousands)
Balance at beginning of period	$	54,846		$	51,651		$	55,002		$	43,611
Accretion	(5,959		)	(5,212		)	(11,731		)	(10,560		)
Reclassification from nonaccretable difference	4,686			7,218			10,302			20,606
Balance at end of period	$	53,573		$	53,657		$	53,573		$	53,657

On the acquisition date, the amount by which the undiscounted expected cash flows exceed the estimated fair value of the PCI loans is the “accretable yield.” The accretable yield is then measured at each financial reporting date and represents the difference between the remaining undiscounted expected cash flows and the current carrying value of the loans. The accretable yield will change from period to period due to the following: 1) estimates of the remaining life of acquired loans will affect the amount of future interest income; 2) indices for variable rates of interest on PCI loans may change; and 3) estimates of the amount of the contractual principal and interest that will not be collected (nonaccretable difference) may change.

The following tables detail the activity in the allowance for loan losses by portfolio segment for the three and six months ended June 30, 2018 and 2017:

* Unpaid contractual principal balance less charge offs, interest collected applied to principal if on nonaccrual and purchase discounts.

Generally, loans are placed on nonaccrual status if the principal and/or interest payments become 90 days or more past due and/or management deems the collectability of the principal and/or interest to be in question, as well as when required by regulatory requirements. Loans to customers whose financial condition has deteriorated are considered for nonaccrual status whether or not the loan is 90 days or more past due. Generally, payments received on nonaccrual loans are recorded as principal reductions. Loans are returned to accrual status only when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The Company did not recognize any cash basis interest income for the three and six months ended June 30, 2018 or 2017.

The following table represent the recorded investment in nonaccrual and loans past due over 90 days or more and still on accrual status by class of loans as of June 30, 2018 and December 31, 2017.

⁽¹⁾  Acquired Loans exclude PCI loans.

Loans accounted for under ASC 310-30 are generally considered accruing and performing loans and the accretable discount is accreted to interest income over the estimated life of the loan when cash flows are reasonably estimable. Accordingly, PCI loans that are contractually past due are still considered to be accruing and performing loans. The loans may be classified as nonaccrual if the timing and amount of future cash flows is not reasonably estimable.

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including, but not limited to, current financial information, historical payment experience, credit documentation, public information, and current economic trends. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes all non-homogeneous loans. Homogeneous loans are not risk rated and credit risk is analyzed largely by the number of days past due. This analysis is performed at least on a quarterly basis. The definitions for risk ratings are as follows:

• Pass: Loans that meet a preponderance or more of the Company’s underwriting criteria and evidence an acceptable level of risk.

• Special Mention: Loans that have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

• Substandard: Loans that are inadequately protected by the current net worth and paying capacity of the borrower or by the collateral pledged, if any. Loans in this classification have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

• Doubtful: Loans that have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or repayment in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

The following tables present the recorded investment of risk ratings for Legacy and Acquired Loans as of June 30, 2018 and December 31, 2017 by class of loans:

The Company may reclassify loans held for investment to loans held for sale in the event that the Company plans to sell loans that were originated with the intent to hold to maturity. Loans transferred from held to investment to held for sale are carried at the lower of cost or fair value. The breakdown of loans by type that were reclassified from held to investment to held for sale for the three and six months ended June 30, 2018 and 2017 is presented in the following table:

The adequacy of the allowance for loan losses is determined by management based upon an evaluation and review of the credit quality of the loan portfolio, consideration of historical loan loss experience, relevant internal and external factors that affect the collection of a loan, and other pertinent factors.

Migration analysis is a formula methodology derived from the Bank’s actual historical net charge off experience for each loan class (type) or pool and risk grade. The migration analysis is centered on the Bank’s internal credit risk rating system. Management’s internal loan review and external contracted credit review examinations are used to determine and validate loan risk grades. This credit review system takes into consideration factors such as: borrower’s background and experience; historical and current financial condition; credit history and payment performance; economic conditions and their impact on various industries; type, fair value and volatility of the fair value of collateral; lien position; and the financial strength of any guarantors.

A general loan loss allowance is provided on loans not specifically identified as impaired (“non-impaired loans”). The Bank’s general loan loss allowance has two components: quantitative and qualitative risk factors. The quantitative risk factors are based on the migration analysis methodology described above. The loans are classified by class and risk grade, and the historical loss migration is tracked for the various classes. Loss experience is quantified for a specified period and then weighted to place more significance on the most recent losses. That loss experience is then applied to the stratified portfolio at the end of each quarter. The Company utilizes nineteen non-homogeneous loan pools in the quantitative analysis process. The non-impaired commercial real estate loan portfolio is stratified into fourteen different loan pools based on property types and the non-impaired commercial and industrial loan portfolio is stratified into five different loan pools based on loan type in order to allocate historic loss experience to more granular loan pools.

Additionally, in order to systematically quantify the credit risk impact of other trends and changes within the loan portfolio, the Bank utilizes qualitative adjustments to the migration analysis within established parameters. The parameters for making adjustments are established under a Credit Risk Matrix that provides seven possible scenarios for each of the factors below. The matrix allows for up to three positive (Major, Moderate, and Minor), three negative (Major, Moderate, and Minor), and one neutral credit risk scenarios within each factor for each loan type or pool. However, if information exists to warrant adjustment to the migration analysis, changes are made in accordance with the established parameters supported by narrative and/or statistical analysis. The Credit Risk Matrix and the nine possible scenarios enable the Bank to qualitatively adjust the Loss Migration Ratio by as much as 50 basis points in either direction (positive or negative) for each loan type pool. This matrix considers the following nine factors, which are patterned after the guidelines provided under the FFIEC Interagency Policy Statement on the Allowance for Loan and Lease Losses:

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

• Changes in national and local economic and business conditions and developments, including the condition of various market segments;

• Changes in the nature and volume of the loan portfolio;

• Changes in the experience, ability and depth of lending management and staff;

• Changes in the trends of the volume and severity of past due loans, classified loans, nonaccrual loans, troubled debt restructurings and other loan modifications;

• Changes in the quality of the loan review system and the degree of oversight by the Directors;

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

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

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

The Company also establishes specific loss allowances for loans that have identified potential credit risk conditions or circumstances related to a specific individual credit. The specific allowance amounts are determined in accordance with ASC 310-10-35-22, “Measurement of Impairment.” The loans identified as impaired will be accounted for in accordance with one of the three acceptable valuation methods: 1) the present value of future cash flows discounted at the loan’s effective interest rate; 2) the loan’s observable market price; or 3) the fair value of the collateral, if the loan is collateral dependent. For the collateral dependent impaired loans, management obtains a new appraisal to determine the amount of impairment as of the date that the loan became impaired. The appraisals are based on an “as is” valuation. To ensure that appraised values remain current, management either obtains updated appraisals every twelve months from a qualified independent appraiser or an internal evaluation of the collateral is performed by qualified personnel. If the third party market data indicates that the value of the collateral property has declined since the most recent valuation date, management adjusts the value of the property downward to reflect current market conditions. If the fair value of the collateral is less than the recorded amount of the loan, management recognizes impairment by creating or adjusting an existing valuation allowance with a corresponding charge to the provision for loan losses. If an impaired loan is expected to be collected through liquidation or operation of the underlying collateral, the loan is deemed to be collateral dependent and the amount of impairment is charged off against the allowance for loan losses.

The Company considers a loan to be impaired when it is probable that not all amounts due (principal and interest) will be collectible in accordance with the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The significance of payment delays and payment shortfalls is determined on a case-by-case basis by taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed.

For commercial business loans, real estate loans, and certain consumer loans, management bases the measurement of loan impairment on the present value of the expected future cash flows, discounted at the loan’s effective interest rate, or on the fair value of the loan’s collateral if the loan is collateral dependent. The scope for evaluation of individual impairment includes all loans risk graded Doubtful or Loss, all troubled debt restructured loans (“TDRs”) and all loans risk graded Substandard that are greater than $500 thousand regardless of performance under their contractual terms. Management evaluates most consumer loans for impairment on a collective basis because these loans generally have smaller balances and are homogeneous in the underwriting of terms and conditions and in the types of collateral. If a loan is deemed to be impaired, the amount of the impairment is supported by a specific allowance amount which is included in the allowance for loan losses through a charge to the provision for loan losses.

For PCI loans, the allowance for loan losses is based upon expected cash flows for these loans. To the extent that a deterioration in borrower’s credit quality results in a decrease in expected cash flows subsequent to the acquisition of the loans, an allowance for loan losses would be established based on an estimate of future credit losses over the remaining life of the loans. Credit for loan losses on acquired loans for the three months ended June 30, 2018 was $253 thousand which included $449 thousand in credit for loan losses related to PCI loans. Credit for loan losses on acquired loans for the six months ended June 30, 2018 was $2.5 million which included $637 thousand in credit for loan losses related to PCI loans.

Under certain circumstances, the Company provides borrowers relief through loan modifications. These modifications are either temporary in nature (“temporary modifications”) or are more substantive. The temporary modifications generally consist of interest only payments for a three to six month period, whereby principal payments are deferred. At the end of the modification period, the remaining principal balance is re-amortized based on the original maturity date. Loans subject to temporary modifications are generally downgraded to Special Mention or Substandard. At the end of the modification period, the loan either 1) returns to the original contractual terms; 2) is further modified and accounted for as a troubled debt restructuring in accordance with ASC 310-10-35; or 3) is disposed of through foreclosure or liquidation.

Troubled Debt Restructurings (“TDRs”) of loans are defined by ASC 310-40, “Troubled Debt Restructurings by Creditors” and evaluated for impairment in accordance with ASC 310-10-35. The concessions may be granted in various forms, including reduction in the stated interest rate, reduction in the amount of principal amortization, forgiveness of a portion of a loan balance or accrued interest, or extension of the maturity date. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed on the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Bank’s internal underwriting policy. At June 30, 2018, total TDR loans were $69.6 million, compared to $78.5 million at December 31, 2017.

A summary of the recorded investment of TDRs on accrual and nonaccrual status by type of concession as of June 30, 2018 and December 31, 2017 is presented below:

TDRs on accrual status are comprised of loans that were accruing at the time of restructuring and for which the Bank anticipates full repayment of both principal and interest under the restructured terms. TDRs that are on nonaccrual status can be returned to accrual status after a period of sustained performance, generally determined to be six months of timely payments as modified.  Sustained performance includes the periods prior to the modification if the prior performance met or exceeded the modified terms. TDRs on accrual status at June 30, 2018 were comprised of 21 commercial real estate loans totaling $26.3 million, 35 commercial business loans totaling $15.7 million, and 43 other loans totaling $7.2 million. TDRs on accrual status at December 31, 2017 were comprised of 24 commercial real estate loans totaling $32.8 million, 27 commercial business loans totaling $27.0 million and 56 other loans totaling $7.5 million. The Company expects that TDRs on accrual status as of June 30, 2018, which were all performing in accordance with their restructured terms, to continue to comply with the restructured terms because of the reduced principal or interest payments on these loans. TDRs that were restructured at market interest rates and had sustained performance as agreed under the modified loan terms may be reclassified as non-TDRs after each year end but are reserved for under ASC 310-10.

The Company has allocated $3.9 million and $4.8 million of specific reserves to TDRs as of June 30, 2018 and December 31, 2017, respectively.

Borrowings

Borrowings

The Company maintains a line of credit with the Federal Home Loan Bank (“FHLB”) of San Francisco as a secondary source of funds. The borrowing capacity with the FHLB is limited to the lower of 25% of the Bank’s total assets or the Bank’s collateral capacity, which was $3.63 billion at June 30, 2018, and $3.54 billion at December 31, 2017. The terms of this credit facility require the Company to pledge eligible collateral with the FHLB equal to at least 100% of outstanding advances.

At June 30, 2018 and December 31, 2017, real estate secured loans with a carrying amount of approximately $5.82 billion and $4.91 billion, respectively, were pledged at the FHLB for outstanding advances and remaining borrowing capacity. At June 30, 2018 and December 31, 2017, other than FHLB stock, no securities were pledged as collateral at FHLB. The purchase of FHLB stock is a prerequisite to become a member of the FHLB system, and the Company is required to own a certain amount of FHLB stock based on outstanding borrowings.

At June 30, 2018 and December 31, 2017, FHLB advances totaling $837.0 million and $1.16 billion, respectively, had weighted average effective interest rates of 1.76% and 1.63%, respectively. FHLB advances at June 30, 2018 and December 31, 2017 had various maturities through December 2022. The effective interest rate of FHLB advances as of June 30, 2018 ranged between 1.06% and 2.39%. At June 30, 2018, the Company’s remaining borrowing capacity with the FHLB was $2.76 billion.

At December 31, 2017, the Company also had $69.9 million in overnight federal funds purchased from lines at other banks. There were no federal funds purchased from other banks at June 30, 2018.

At June 30, 2018, the contractual maturities for FHLB advances were as follows:

Subordinated Debentures and Convertible Notes

Subordinated Debentures and Convertible Notes

Subordinated Debt

At June 30, 2018, the Company had nine wholly owned subsidiary grantor trusts that had issued $126.0 million of pooled trust preferred securities. Trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in the indentures. The trusts used the net proceeds from the offering to purchase a like amount of subordinated debentures (the “Debentures”). The Debentures are the sole assets of the trusts. The Company’s obligations under the subordinated debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon the maturity of the Debentures, or upon earlier redemption as provided in the indentures. The Company has the right to redeem the Debentures in whole (but not in part) on a quarterly basis at a redemption price specified in the indentures plus any accrued but unpaid interest to the redemption date. The Company also has a right to defer consecutive payments of interest on the debentures for up to five years.

The following table is a summary of trust preferred securities and Debentures at June 30, 2018:

Issuance Trust	Issuance Date	Trust Preferred Security Amount		Carrying Value of Debentures		Rate Type	Current Rate	Maturity Date
		(Dollars in thousands)
Nara Capital Trust III	06/05/2003	$	5,000	$	5,155	Variable	5.49%	06/15/2033

The Company’s investment in the common trust securities of the issuer trusts was $3.9 million at June 30, 2018 and is included in other assets. Although the subordinated debt issued by the trusts is not included as a component of stockholders’ equity in the consolidated statements of financial condition, the debt is treated as capital for regulatory purposes. The trust preferred security debt issuances are includable in Tier I capital up to a maximum of 25% of capital on an aggregate basis. Any amount that exceeds 25% qualifies as Tier 2 capital.

Under the “Merger and Acquisition Transition Provisions” in BASEL III, if a depository institution holding company of $15 billion or more acquires a depository institution holding company with total consolidated assets of less than $15 billion as of December 31, 2009, the non-qualifying capital instruments of the resulting organization will be subject to a phase-out schedule. The phase-out schedule ended in 2016 and therefore in accordance with BASEL III, the Company’s subordinated debenture will no longer qualify for Tier 1 capital treatment once the Company exceeds total consolidated assets of $15 billion or more since the Company had acquisitions subsequent to December 31, 2009. The subordinated debentures will be still be eligible for Tier 2 inclusion once the Company exceeds $15 billion or more in total consolidated assets.

Convertible Notes

On May 11, 2018, the Company issued $200 million aggregate principal amount of 2.00% convertible senior notes maturing on May 15, 2038 in a private offering to qualified institutional investors under Rule 144A of the Securities Act of 1933. Subsequently on June 7, 2018, an additional $17.5 million in convertible notes were issued as part of the initial offering over-allotment option. In total, the Company issued $217.5 million in convertible notes during the second quarter of 2018. The convertible notes can be converted to the Company’s share of common stock at an initial rate of 45.0760 shares per $1,000 principal amount of the notes (equivalent to an initial conversion price of approximately $22.18 per share of common stock which represents a premium of 22.5% to the closing stock price on the date of the pricing of the notes). The convertible notes can be called by the Company, in part or in whole, on or after May 20, 2023 for 100% of the principal amount in cash. Holders of the convertible notes also have the option to repurchase or put the notes on May 15, 2023, May 15, 2028, or May 15, 2033 for 100% of the principal amount in cash.

The convertible notes were issued as part of the Company’s plan to repurchase its common stock. On April 26, 2018, the Company’s Board of Directors approved a share repurchase program that authorized the Company to use up to $100.0 million of the proceeds from the convertible notes offering to repurchase its common stock. The net proceeds from the offering, after deducting the initial purchaser’s discount, was approximately $213.2 million. Of the total net proceeds, $113.2 million was down-streamed to the Bank as equity and the remaining $100.0 million was allocated for share repurchases. The Company used approximately $76.0 million of the allocated $100.0 million for share repurchases to repurchase shares of its common stock from purchasers of the convertible notes in privately negotiated transactions at a purchase price per share equal to the $18.11 per share closing price of the Company’s common stock. Subsequently, the Company repurchased additional shares of common stock on the open market. At June 30, 2018, total shares repurchased by the Company was $79.0 million, or 4.4 million shares at a weighted average price of $18.1032.

In accordance with accounting principles, the convertible notes issued by the Company were separated into a debt component and an equity component which represents the stock conversion option. The present value of the convertible notes was calculated based on a discount rate of 4.25%, which represented the current offering rate for similar types of debt without conversion options. The effective life of the convertible notes was estimated to be five years based on the first call and put date. The difference between the principal amount of the notes and the present value was recorded as the convertible note discount and additional paid-in capital. The issuance costs related to the offering were also allocated into a debt component to be capitalized, and an equity component in the same percentage allocation of debt and equity of the convertible note. The value of the convertible note at issuance and carrying value as of June 30, 2018 is presented below:

		As of June 30, 2018
	Amortization/ Capitalization Period	Gross Carrying Amount			Accumulated Amortization / Capitalization		Carrying Amount

Convertible notes principal balance		$	217,500		$	—	$	217,500
Discount	5 years	(21,880		)	518		(21,362		)
Issuance costs to be capitalized	5 years	(4,119		)	101		(4,018		)
Carrying balance of convertible notes		$	191,501		$	619	$	192,120

Interest expense on the convertible notes for the three and six months ended June 30, 2018 totaled $1.2 million. Interest expense for the Company’s convertible notes includes accrued interest on the convertible note coupon, non-cash interest expense representing the conversion option or note discount, and interest expense from capitalized issuance costs. Non-cash interest expense and issuance cost capitalization expense will only be recorded for the first five outstanding years of the convertible note. Subsequent to May 15, 2023, interest expense on the convertible note will consist of only accrued interest on the coupon.

Derivative Financial Instruments

Derivative Financial Instruments

The Company offers a loan hedging program to certain loan customers. Through this program, the Company originates a variable rate loan with the customer. The Company and the customer will then enter into a fixed interest rate swap. Lastly, an identical offsetting swap is entered into by the Company with a correspondent bank. These “back-to-back” swap arrangements are intended to offset each other and allow the Company to book a variable rate loan, while providing the customer with a contract for fixed interest payments. In these arrangements, the Company’s net cash flow is equal to the interest income received from the variable rate loan originated with the customer. These customer swaps are not designated as hedging instruments and are recorded at fair value in other assets and other liabilities. The changes in fair value is recognized in the income statement in other income and fees.

At June 30, 2018 and December 31, 2017, interest rate swaps related to the Company’s loan hedging program that were outstanding is presented in the following table:

	As of June 30, 2018			As of December 31, 2017

The Company enters into various stand-alone mortgage-banking derivatives in order to hedge the risk associated with the fluctuation of interest rates. Changes in fair value are recorded as mortgage banking revenue. Residential mortgage loans funded with interest rate lock commitments and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. At June 30, 2018, the Company had approximately $2.1 million in interest rate lock commitments and total forward sales commitments for the future delivery of residential mortgage loans. At December 31, 2017, the Company had approximately $4.8 million in interest rate lock commitments and total forward sales commitments for the future delivery of residential mortgage loans.

Commitments and Contingencies

Commitments and Contingencies

In the normal course of business, the Company is a party to financial instruments with off-balance sheet risk that are used to meet the financing needs of customers. These financial instruments include commitments to extend credit, standby letters of credit, commercial letters of credit, commitments to fund investments in affordable housing partnerships, mortgage derivatives, and operating lease commitments. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. The Company’s exposure to credit loss in the event of nonperformance on commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as the Company does for extending loan facilities to customers. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on the Company’s credit evaluation of the counterparty. The types of collateral that the Company may hold can vary and may include accounts receivable, inventory, property, plant and equipment, and income-producing properties.

Commitments at June 30, 2018 and December 31, 2017 are summarized as follows:

	June 30, 2018		December 31, 2017
	(Dollars in thousands)
Commitments to extend credit	$	1,676,694	$	1,526,981

Commitments to fund investments in affordable housing partnerships	38,056		38,467
Interest rate lock	2,107		4,795
Forward sale commitments	2,107		4,795
Operating lease commitments	69,304		66,698

In the normal course of business, the Company is involved in various legal claims. The Company has reviewed all legal claims against us with counsel and have taken into consideration the views of such counsel as to the potential outcome of the claims. Loss contingencies for all legal claims totaled $420 thousand at June 30, 2018 and $414 thousand at December 31, 2017. It is reasonably possible the Company may incur losses in addition to the amounts currently accrued. However, at this time, the Company is unable to estimate the range of additional losses that are reasonably possible because of a number of factors, including the fact that certain of these litigation matters are still in their early stages and involve claims that the Company believes have little to no merit. Management has considered these and other possible loss contingencies and does not expect the amounts to be material to the consolidated financial statements.

Goodwill, Intangible Assets, and Servicing Assets

Goodwill, Intangible Assets, and Servicing Assets

Goodwill represents the excess of the purchase price over the sum of the estimated fair values of the tangible and identifiable intangible assets acquired less the estimated fair value of the liabilities assumed. Goodwill has an indefinite useful life and is evaluated for impairment annually or more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. At December 31, 2017, management assessed the qualitative factors related to intangible assets and goodwill and for the year to determine whether it was more-likely-than-not that the fair value was less than its carrying amount. Based on the analysis of these factors, management determined that it was more-likely-than-not that intangible assets were not impaired and that the fair value of goodwill exceeded the carrying value and that the two-step goodwill impairment test was not needed. Goodwill is not amortized for book purposes and is not tax deductible.

The carrying amount of the Company’s goodwill as of June 30, 2018 and December 31, 2017 was $464.5 million. There was no impairment of goodwill during the three and six months ended June 30, 2018.

Core deposit intangible assets are amortized over their estimated lives, which range from seven to ten years. Amortization expense related to core deposit intangible assets totaled $615 thousand and $676 thousand for the three months ended June 30, 2018 and 2017, respectively. The amortization expense related to core deposit intangible assets totaled $1.2 million and $1.4 million for the six months ended June 30, 2018 and 2017, respectively. The following table provides information regarding the core deposit intangibles at June 30, 2018:

		As of June 30, 2018

Total		$	25,605	$	(10,313	)	$	15,292

Servicing assets are recognized when SBA and residential mortgage loans are sold with servicing retained with the income statement effect recorded in gains on sales of loans. Servicing assets are initially recorded at fair value based on the present value of the contractually specified servicing fee, net of 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 40 basis points. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans.

Management periodically evaluates servicing assets for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is determined by stratifying rights into groupings based on loan type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. As of June 30, 2018 and December 31, 2017, the Company did not have a valuation allowance for servicing assets.

The changes in servicing assets for the three and six months ended June 30, 2018 and 2017 were as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2018			2017			2018			2017

Balance at end of period	$	25,050		$	25,338		$	25,050		$	25,338

Loans serviced for others are not reported as assets. The principal balances of loans serviced for other institutions were $1.54 billion as of June 30, 2018 and $1.51 billion as of December 31, 2017.

The Company utilizes the discounted cash flow method to calculate the initial excess servicing assets. The inputs used in evaluating servicing assets for impairment at June 30, 2018 and December 31, 2017 are presented below.

	June 30, 2018	December 31, 2017

Income Taxes

Income Taxes

For the three months ended June 30, 2018, the Company had an income tax provision totaling $16.6 million on pretax income of $64.2 million, representing an effective tax rate of 25.92%, compared with an income tax provision of $25.5 million on pretax income of $66.1 million, representing an effective tax rate of 38.48% for the three months ended June 30, 2017. For the six months ended June 30, 2018, the Company had an income tax provision totaling $34.4 million on pretax income of $133.1 million, representing an effective tax rate of 25.81%, compared with an income tax provision of $48.5 million on pretax income of $125.3 million, representing an effective tax rate of 38.65% for the six months ended June 30, 2017. The reduction in effective tax rate for periods in 2018 compared to periods 2017 was primarily due to the reduction of federal income tax rate from 35% to 21% under comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (“Tax Act”) effective as of December 22, 2017, but the increase in affordable housing partnership investment tax credits for the three and six months ended June 30, 2018 compared to the three and six months ended June 30, 2017, also contributed to the decline in the tax rate.

As of June 30, 2018, the Company has not yet completed accounting for the enactment of the Tax Act; however, the Company believes it has reasonably estimated the effects of the Tax Act by recording an income tax expense of $25.4 million for the year ended December 31, 2017 in accordance with SEC Staff Accounting Bulletin No. 118 (“SAB 118”). As required by SAB 118, the Company will continue to evaluate and re-measure the impact of the Tax Act on deferred tax amounts that existed at December 31, 2017 and record appropriate income tax provision amounts in 2018. As a result of this process, through the second quarter of 2018, the Company recorded an additional income tax provision expense of $16 thousand for the six months ended June 30, 2018.

The Company and its subsidiaries are subject to U.S. federal income tax, as well as state income taxes. The Company had total unrecognized tax benefits of $2.4 million at June 30, 2018 and $2.1 million at December 31, 2017, that relate to uncertainties associated with federal and state income tax matters. The Company recognizes interest and penalties on income tax matters in income tax expense. The Company recorded approximately $438 thousand and $348 thousand, for accrued interest (no portion was related to penalties) at June 30, 2018 and December 31, 2017, respectively.

Management believes it is reasonably possible that the unrecognized tax benefits may decrease by $2.4 million in the next twelve months due to a settlement with the state tax authorities.

The statute of limitations for the assessment of income taxes 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 for the assessment of income and franchise taxes related to the various state income and franchise tax returns varies by state. The Company is currently under examination by the California Franchise Tax Board (FTB) for the 2011, 2012 and 2013 tax years and by the New York State Department of Taxation and Finance for the 2013, 2014, and 2015 tax years. Wilshire Bancorp, Inc., an acquired entity, is currently under examination by the FTB for the 2011, 2012, and 2013 tax years. While the outcome of the examinations is unknown, the Company expects no material adjustments.

Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities (without regard to certain changes to deferred taxes). Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In assessing the realization of deferred tax assets, management evaluates both positive and negative evidence, including the existence of any cumulative losses in the current year and the prior two years, the amount of taxes paid in available carry-back years, the forecasts of future income, applicable tax planning strategies, and assessments of current and future economic and business 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 June 30, 2018.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair value. The fair value inputs of the instruments are classified and disclosed in one of the following categories pursuant to ASC 820:

Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. The quoted price shall not be adjusted for any blockage factor (i.e., size of the position relative to trading volume).

Level 2 - Pricing inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Fair value is determined through the use of models or other valuation methodologies, including the use of pricing matrices. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 - Pricing inputs are unobservable for the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. The inputs into the determination of fair value require significant management judgment or estimation.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

The Company uses the following methods and assumptions in estimating fair value disclosures for financial instruments. Financial assets and liabilities recorded at fair value on a recurring and non-recurring basis are listed as follows:

Securities Available for Sale

The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs).

The fair values of the Company’s Level 3 securities available for sale were measured using an income approach valuation technique. The primary inputs and assumptions used in the fair value measurement were derived from the securities’ underlying collateral, which included discount rates, prepayment speeds, payment delays, and an assessment of the risk of default of the underlying collateral, among other factors. Significant increases or decreases in any of the inputs or assumptions would result in a significant increase or decrease in the fair value measurement.

Equity Investments With Readily Determinable Fair Value

The fair value of our equity investments with readily determinable fair value is comprised of mutual funds and equity stock. The fair value for these investments is obtained from unadjusted quoted prices in active markets on the date of measurement and is therefore classified as Level 1.

Interest Rate Swaps

The Company offers interest rate swaps to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps is classified as Level 2.

Mortgage banking derivatives

Mortgage banking derivative instruments consist of interest rate lock commitments and forward sale contracts that trade in liquid markets. The fair value is based on the prices available from third party investors. Due to the observable nature of the inputs used in deriving the fair value, the valuation of mortgage banking derivatives are classified as Level 2.

Impaired Loans

The fair values of impaired loans are generally measured for impairment using the practical expedients permitted by FASB ASC 310-10-35 including impaired loans measured at an observable market price (if available), or at the fair value of the loan’s collateral (if the loan is collateral dependent). Fair value of the loan’s collateral, when the loan is dependent on collateral, is determined by appraisals or independent valuation, less costs to sell of 8.5%. For commercial and industrial and asset backed loans, independent valuations may be comprised of a 20-60% discount for eligible accounts receivable and a 50-70% discount for inventory. These result in a Level 3 classification.

OREO

OREO is fair valued at the time the loan is foreclosed upon and the asset is transferred to OREO. The value is based primarily on third party appraisals, less costs to sell of 8.5% and result in a Level 3 classification of the inputs for determining fair value. OREO is reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted to lower of cost or market accordingly, based on the same factors identified above.

Loans held for sale

Loans held for sale are carried at the lower of cost or fair value, as determined by outstanding commitments from investors, or based on recent comparable sales (Level 2 inputs), if available, and if not available, are based on discounted cash flows using current market rates applied to the estimated life and credit risk (Level 3 inputs) or may be assessed based upon the fair value of the collateral, which is obtained from recent real estate appraisals (Level 3 inputs). These appraisals may utilize a single valuation approach or a combination of approaches including the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in Level 3 classification of the inputs for determining fair value.

During the first quarter of 2018, the Company adopted ASU 2016-01, “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” Among other things, the guidance requires the Company to base their fair value disclosures for financial instruments that are not measured at fair value in the financial statements on the exit price notion as opposed to an entry pricing notion. As of December 31, 2017, the Company used the entry prices to measure the fair value of certain assets and liabilities including loans, deposits, and subordinated debentures as permitted by ASC 820-10. However, upon adoption of ASU 2016-01, the Company began measuring these assets and liabilities based on the exit price notion. Although the exit price notion represents the value that would be received to sell an asset or paid to transfer a liability, the actual price received for a sale of assets or paid to transfer liabilities could be different from exit price disclosed.

The methods and assumptions used to estimate fair value are described as follows:

The carrying amount is the estimated fair value for cash and cash equivalents, savings and other interest bearing demand deposits, customer’s and Bank’s liabilities on acceptances, noninterest bearing deposits, short-term debt, secured borrowings and variable rate loans or deposits that reprice frequently and fully. For loans the fair value is determined through a discounted cash flow analysis which incorporates probability of default and loss given default rates on an individual loan basis. The discount rate is based on the LIBOR Swap Rate for fixed rate loans, while variable loans start with the corresponding index rate and an adjustment was made on certain loans which considered factors such as servicing costs, capital charges, duration, asset type incremental costs, and use of projected cash flows. Residential real estate loans fair values included Fannie Mae and Freddie Mac prepayment speed assumptions or a third party index based on historical prepayment speeds. Fair value of time deposits is based discounted cash flow analysis using recent issuance rates over the prior three months and a market rate analysis of recent offering rates for retail products. Wholesale time deposits fair values incorporated brokered time deposit offering rates. The fair value of the Company’s debt is based on current rates for similar financing. Fair value for the Company’s convertible notes is based on the actual last traded price of the notes. It was not practicable to determine the fair value of FRB stock or FHLB stock due to restrictions placed on their transferability. The fair value of commitments to fund loans represents fees currently charged to enter into similar agreements with similar remaining maturities and is not presented herein. The fair value of these financial instruments is not material to the consolidated financial statements.

Equity [Abstract]

Stockholders’ Equity

Stockholders’ Equity

Total stockholders’ equity at June 30, 2018 was $1.91 billion, compared to $1.93 billion at December 31, 2017.

The Company assumed certain warrants (related to the TARP Capital Purchase Plan) to purchase shares of the Company’s common stock. On May 20, 2015, the U.S. Treasury Department completed an auction to sell certain warrant positions, and the Company submitted the winning bid to repurchase an outstanding warrant to purchase 350,767 shares of the Company’s common stock. The Company repurchased this warrant for $1.2 million. As of June 30, 2018, the U.S. Treasury Department held one remaining warrant for the purchase of 20,673 shares of the Company’s common stock.

During the second quarter of 2018, the Company recorded $21.4 million in additional paid-in capital from the convertible notes issued. The $21.4 million included $21.9 million for the equity component of the convertible notes offset by $461 thousand in issuance costs from the convertible notes that was allocated to equity. The Company also recorded a tax adjustment on the equity component of the convertible notes reducing additional paid-in capital by $6.4 million.

On April 26, 2018, the Company’s Board of Directors approved a share repurchase program that authorized the Company to repurchase up to $100.0 million in common stock. During the second quarter of 2018, the Company repurchased 4.4 million shares of common stock which was recorded as treasury stock totaling $79.0 million. This led to a decline in stockholders’ equity at June 30, 2018 compared to December 31, 2017.

The Company paid a quarterly dividend of $0.13 per common share for the second quarter of 2018 compared to $0.12 per common share for the second quarter of 2017. For the six months ended June 30, 2018 and 2017, the Company paid total dividends of $0.26 and $0.24 per common share, respectively.

The following table presents the quarterly changes to accumulated other comprehensive (loss) income for the three and six months ended June 30, 2018 and June 30, 2017:

During the first quarter of 2018, the Company adopted ASU 2016-01 “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” As a result of the adoption of ASU 2016-01, the Company no longer accounts for mutual funds as available-for-sale securities and accounts for these investments as equity investments with changes to fair value recorded through earnings. In accordance with ASU 2016-01, the Company reclassified $281 thousand in net unrealized losses included in other comprehensive income, net of taxes, at December 31, 2017 to retained earnings on January 1, 2018. For the three and six months ended and June 30, 2018 and 2017, there were no other reclassifications out of accumulated other comprehensive (loss) income.

Banking and Thrift [Abstract]

Regulatory Matters

Regulatory Matters

The Company and the Bank are subject to various regulatory capital requirements administered by the federal and state 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 material and adverse effect on the Company’s and the Bank’s business, financial condition and results of operation, such as restrictions on growth or the payment of dividends or other capital distributions or management fees. 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 their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

In July, 2013, the federal bank regulatory agencies adopted final regulations, which revised their risk-based and leverage capital requirements for banking organizations to meet requirements of Dodd-Frank and to implement Basel III international agreements reached by the Basel Committee. The final rules began for the Company and the Bank on January 1, 2015 and are subject to a phase-in period through January 1, 2019. The final rules that had an impact on the Company and the Bank include:

• An increase in the minimum Tier 1 capital ratio from 4.00% to 6.00% of risk-weighted assets;

• A new category and a required 4.50% of risk-weighted assets ratio is established for “Common Equity Tier 1” as a subset of Tier 1 capital limited to common equity;

• A minimum non-risk-based leverage ratio is set at 4.00%, eliminating a 3.00% exception for higher rated banks;

• Changes in the permitted composition of Tier 1 capital to exclude trust preferred securities, mortgage servicing rights and certain deferred tax assets and include unrealized gains and losses on available for sale debt and equity securities;

• The risk-weights of certain assets for purposes of calculating the risk-based capital ratios are changed for high volatility commercial real estate acquisition, development and construction loans, certain past due non-residential mortgage loans and certain mortgage-backed and other securities exposures; and

• A new additional capital conservation buffer of 2.5% of risk weighted assets over each of the required capital ratios is being phased in from 2016 to 2019 and must be met to avoid limitations on the ability of the Bank to pay dividends, repurchase shares, or pay discretionary bonuses. The capital conservation buffer for the Company was initially 0.625% in 2016, and increases 0.625% annually until 2019. As ofJune 30, 2018, the capital conservation buffer for the Company stood at 1.875%.

As of June 30, 2018, the ratios for the Company and the Bank were sufficient to meet the fully phased-in conservation buffer.

As of June 30, 2018 and December 31, 2017, the most recent regulatory notification categorized the Bank as “well-capitalized” under the regulatory framework for prompt corrective action. To generally be categorized as “well-capitalized”, the Bank must maintain minimum total risk-based, Tier I risk-based, common equity Tier 1, and Tier I leverage ratios as set forth in the following table. There are no conditions or events since the most recent notification from regulators that management believes has changed the institution’s category.

The Company’s and the Bank’s capital amounts and ratios are presented in the table below for the dates indicated:

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Revenue Recognition

On January 1, 2018, the Company adopted ASU No. 2014-09 “Revenue from Contracts with Customers” (Topic 606) and all subsequent issued ASUs that are related to Topic 606. The implementation of the new standard did not have a material impact on the measurement or recognition of revenue; as such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period results were not adjusted and continue to be reported in accordance with previous accounting guidance under Topic 605.

Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also out of scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as deposit related fees, wire transfer fees, and OREO related net gains or expenses. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Noninterest revenue streams in-scope of Topic 606 are discussed below.

Service Charges on Deposit Accounts and Wire Transfer Fees

Service charges on noninterest and interest bearing deposit accounts consist of monthly service charges, customer analysis charges, non-sufficient funds (“NSF”) charges, other deposit account related charges, and wire transfer fees. The Company’s performance obligation for account analysis charges and monthly service charges is generally satisfied, and the related revenue recognized, over the period in which the service is provided. NSF charges and other deposit account related charges are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts.

Service charges on deposit accounts and wire transfers are summarized below:

	Three Months Ended June 30,				Six Months Ended June 30

OREO is often sold in a transaction that, under ASU 2014-09, may not be considered a contract with a customer because the sale of the asset may not be an output of the Company’s ordinary activities. However, sales of nonfinancial assets, including in-substance nonfinancial assets, should be accounted for in accordance with ASC Subtopic 610-20, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets”, which requires the Company to apply certain measurement and recognition concepts of ASC 606. Accordingly, the Company recognizes the sale of a real estate property, along with any associated gain or loss, when control of the property transfers to the buyer. For sales of existing real estate properties, this generally will occur at a point in time. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. Application of the new revenue recognition standard does not materially change the amount and the timing of the gain/loss on sale of OREO and other nonfinancial assets. Further, there were no open OREO/nonfinancial assets sale contracts at the adoption date that required an evaluation under Topic 606. The Company recognized a gain on sale of OREO of $79 thousand and $86 thousand for the three months ended June 30, 2018 and 2017, respectively. For the six months ended June 30, 2018 and 2017, the Company recognized a gain on sale of OREO of $151 thousand and $82 thousand, respectively.

Basis Of Presentation [Abstract]

Consolidation

The consolidated financial statements include the accounts of Hope Bancorp and its wholly owned subsidiaries, principally Bank of Hope. All intercompany transactions and balances have been eliminated in consolidation. The Company has made all adjustments, that in the opinion of management, are necessary to fairly present the Company’s financial position at June 30, 2018 and December 31, 2017 and the results of operations for the three and six months ended June 30, 2018 and 2017. Certain reclassifications have been made to prior period amounts to conform to the current year presentation. The results of operations for the interim periods are not necessarily indicative of results to be anticipated for the full year.

Use of estimates

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“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 and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. Subsequently in July 2018, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842, Leases” and ASU 2018-11, “Leases Topic 842, Targeted Improvements”, to provide additional clarification, implementation, and transition guidance on certain aspects of ASU 2016-02. ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 and ASU 2018-10 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. Under ASU 2018-11, an additional transition option was provided that would allow entities to not apply the new guidance in the comparative periods they present in their financial statements in the year of adoption. Under this optional transition method, entities will be allowed to continue using and presenting leases under ASC 840 for prior years comparative periods and then prospectively adopt ASC 842 on January 1, 2019, recognizing a cumulative-effect adjustment to the opening balance of retained earnings. The Company estimated that there are approximately 100 operating leases that will be accounted for under ASU 2016-02 at the adoption date. The Company plans to elect the transition option to not reassess the following at adoption date: whether contracts are or contain leases, the lease classification for any expired or existing leases, and the evaluation of initial direct costs associated with existing leases. In July 2018, the Company engaged a new software vendor to assist the Company with the administration and accounting of leases under ASU 2016-02. The Company is currently in the process of evaluating the financial impact of the pending adoption of the new standard on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, also referred to as “CECL”. ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. ASU 2016-13 becomes effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. The Company has established a CECL committee to oversee the development and implementation of ASU 2016-13. The Company is collaborating with a third party advisory team and has completed a gap assessment, a full implementation road-map and a detailed project plan. The Company has also engaged a software vendor to assist the Company to build a model that is compliant with ASU 2016-13 by the effective date. Based on the Company’s initial assessment of the ASU 2016-13, the Company expects the new guidance will result in additional required allowance for loan losses which could potentially have a material impact on its consolidated financial statements and regulatory capital ratios.

In January 2017, the FASB issued ASU 2017-04, “Intangibles: Goodwill and Other: Simplifying the Test for Goodwill Impairment.” ASU 2017-04 will amend and simplify current goodwill impairment testing to eliminate Step 2 from the current provisions. Under the new guidance, an entity should perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. An entity still has the option to perform the quantitative assessment for a reporting unit to determine if a quantitative impairment test is necessary. ASU 2017-04 should be adopted for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of ASU 2017-04 is not expected to have a material impact on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities”. ASU 2017-08 was issued to amend the amortization period for certain callable debt securities held at a premium. ASU 2017-08 shortens the amortization period of premiums on certain purchased callable debt securities to the earliest call date. ASU 2017-08 affect all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date (that is, at a premium). ASU 2017-08 does not impact securities purchased at a discount, which continue to be amortized to maturity. ASU 2017-08 is effective for annual period beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted in an interim period. If an entity chooses to adopt early, any adjustments should be reflected as of the beginning of the fiscal year that includes the interim period. The adoption of ASU 2017-08 is not expected to have a material impact on the Company’s consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployees Share-Based Payment Accounting”. ASU 2018-07 expands the scope of Topic 718 (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services.  As ASU 2018-07 becomes effective, the accounting for share-based payments for nonemployees and employees will be substantially the same.  The ASU supersedes Subtopic 505-50, Equity – Equity-Based Payments to Non-Employees. ASU 2018-07 is effective for annual period beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted, but no earlier than a company’s adoption date of Topic 606, Revenue from Contracts with Customers.  The adoption of ASU 2018-07 is not expected to have a material impact on the Company’s consolidated financial statements as the Company has not historically issued share-based payments to nonemployees for goods and services.
