Basis of Presentation

Our condensed consolidated financial statements included herein have been prepared without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in consolidated 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 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.

We believe that we have made all adjustments, consisting solely of normal recurring accruals, necessary to fairly present our financial position at March 31, 2012 and the results of our 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.

These unaudited condensed consolidated financial statements should be read along with the audited consolidated financial statements and accompanying notes included in our 2011 Annual Report on Form 10-K.

Adoption of New Accounting Standards:

ASB ASU 2011-04, "Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (Topic 820)"—This ASU provides guidance on fair value measurement and disclosure requirements that the FASB deemed largely identical across U.S. GAAP and IFRS. The requirements do not extend the use of fair value accounting, but provide guidance on how it should be applied where its use is already required or allowed. ASU 2011-04 supersedes most of the guidance in ASC topic 820, but many of the changes are clarifications of existing guidance or wording changes to reflect IFRS 13. Amendments in ASU 2011-04 change the wording used to describe U.S. GAAP requirements for fair value and disclosing information about fair value measurements. ASU 2011-04 is effective for interim and annual reporting periods beginning after December 15, 2011, and early application is not permitted. We adopted ASU 2011-04 on its guidance and disclosures in the consolidated financial statements effective first quarter 2012.

FASB ASU 2011-05, "Presentation of Comprehensive Income (Topic 220)"— This ASU is intended to improve the comparability, consistency, and transparency of financial reporting and to increase the prominence of items reported in other comprehensive income. To increase the prominence of items reported in other comprehensive income and to facilitate convergence of U.S. GAAP and IFRS, the FASB decided to eliminate the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity, among other amendments in this Update. These amendments apply to all entities that report items of other comprehensive income, in any period presented. Under the amendments to Topic 220, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. However, based on an amendment, FASB ASU 2011-12, "Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05," issued in December 2011, companies are not required to present separate line items on the income statement for reclassifications adjustments of items out of accumulated other comprehensive income into net income as would have been required under the initial standard. Companies are required to present reclassification adjustments within other comprehensive income or in the notes to the financial statements. We adopted ASU 2011-05 and presented the components of net income, the components of other comprehensive income, and total comprehensive income in two consecutive statements effective first quarter 2012.

FASB ASU 2011-08, "Intangibles—Goodwill and Other (Topic 350); Testing Goodwill for Impairment"—This ASU permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying amount before applying the two-step goodwill impairment test. If an entity can support the conclusion that is is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it would not need to perform the two-step impairment test for that reporting unit. The ASU is effective for annual and interim goodwill impairment tests performed in fiscal years beginning after December 15, 2011. We adopted ASU 2011-08 effective first quarter 2012.
