Basis Of Presentation [Abstract] |
Consolidation | The condensed consolidated financial statements include the accounts of BBCN Bancorp and its wholly owned subsidiaries, principally BBCN Bank. All intercompany transactions and balances have been eliminated in consolidation. The Company has made all adjustments, consisting solely of normal accruals, that in the opinion of management, are necessary to fairly present the Company’s financial position at March 31, 2016 and the results of operations for the three months then ended. 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 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 from those estimates. Material estimates that are susceptible to change in the near term relate to the determination of the allowance and provision for loan losses, the evaluation of other than temporary impairment of investment securities, accounting for derivatives and hedging activities, the determination of the carrying value for cash surrender value of life insurance, the determination of the carrying value of goodwill and other intangible assets, accounting for deferred tax assets and related valuation allowances, the determination of the fair values of investment securities and other financial instruments, accounting for lease arrangements, accounting for incentive compensation, profit sharing and bonus payments, and the valuation of servicing assets.
Recent Accounting Pronouncements | Recent Accounting Pronouncements: FASB ASU No. 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting or Fees Paid in a Cloud Computing Arrangement. The amendments in ASU 2015-05 provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments do not change the accounting for a customer’s accounting for service contracts. As a result of the amendments, all software licenses within the scope of Subtopic 350-40 will be accounted for consistently with other licenses of intangible assets. The amendments became effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The adoption of ASU 2015-05 did not have a material effect on the Company’s financial statements. FASB ASU No. 2015-10, Technical Corrections and Improvements. The amendments in ASU 2015-10 represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have significant effect on current accounting practice or create a significant administrative cost to most entities. The amendments that require transition guidance became effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2015. The adoption of ASU 2015-10 did not have a significant impact on the Company’s financial statements. FASB ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. The FASB issued guidance that requires an acquirer in a business combination to recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments also require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed at the acquisition date. The amendments became effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2015. The adoption of ASU 2015-16 did not have a significant impact on the Company’s financial statements. FASB ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The amendments eliminate the current requirement for organizations to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The amendments become effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2016. The adoption of ASU 2015-17 is not expected to have a significant impact on the Company’s consolidated financial statements. FASB ASU No. 2016-01, Financial Instruments─Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments require equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The amendments become effective for fiscal years beginning after December 15, 2017. The adoption of ASU 2016-01 is not expected to have a significant impact on the Company’s consolidated financial statements. FASB ASU No. 2016-02, Leases (Topic 842). The new standard 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. The new standard is 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. The Company is evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. FASB ASU No. 2016-07, Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting. The amendments eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments become effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and early adoption is permitted. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. FASB ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). The amendments are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations by amending certain existing illustrative examples and adding additional illustrative examples to assist in the application of the guidance. The amendments become effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. FASB ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments require recognition of all excess tax benefits and tax deficiencies through income tax expense or benefit in the income statement. Other amendments in ASU 2016-09 include guidance on the classification of share based payment transactions in the statement of cash flows and an option to account for forfeitures of share-based awards as they occur rather than estimating the compensation cost based on the number of awards that are expected to vest. The amendments become effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements.
Income taxes | Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. 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.
