Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | The consolidated financial statements include the accounts of Bank of Marin Bancorp (“Bancorp”), a bank holding company, and its wholly-owned bank subsidiary, Bank of Marin (the “Bank”), a California state-chartered commercial bank. References to “we,” “our,” “us” mean the holding company and the Bank that are consolidated for financial reporting purposes. The accompanying unaudited consolidated interim financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to those rules and regulations. Although we believe that the disclosures made are adequate to make the information not misleading, we suggest that these interim financial statements be read in conjunction with the financial statements and the notes thereto included in our 2014 Annual Report on Form 10-K. In the opinion of Management, the unaudited consolidated financial statements reflect all adjustments which are necessary for a fair presentation of the consolidated financial position, the results of operations, changes in comprehensive income, changes in stockholders’ equity, and cash flows for the periods presented. All material intercompany transactions have been eliminated. The results of these interim periods may not be indicative of the results for the full year or for any other period. We have evaluated subsequent events through the date of filing with the SEC and have determined that there are no subsequent events that require additional recognition or disclosure. On November 29, 2013, we completed the merger of NorCal Community Bancorp ("NorCal"), parent company of Bank of Alameda, to enhance our market presence (the “Acquisition”). On the date of acquisition, Bancorp assumed ownership of NorCal Community Bancorp Trusts I and II, respectively (the "Trusts"), which were formed for the sole purpose of issuing trust preferred securities. Bancorp is not considered the primary beneficiary of the Trusts (variable interest entities), therefore the Trusts are not consolidated in our consolidated financial statements, but rather the subordinated debentures are shown as a liability on our consolidated statements of condition. Bancorp's investment in the common stock of the Trusts is accounted for under the equity method and is included in interest receivable and other assets on the consolidated statements of condition.
Earnings Per Share | Basic earnings per share (“EPS”) are calculated by dividing net income by the weighted average number of common shares outstanding during each period, excluding unvested restricted stock awards. Diluted EPS are calculated using the weighted average diluted shares. The number of potentially dilutive common shares included in quarterly diluted EPS is computed using the average market prices during the three months included in the reporting period under the treasury stock method. The number of potentially dilutive common shares included in year-to-date diluted EPS is a year-to-date weighted average of potentially dilutive common shares included in each quarterly diluted EPS computation. We have two forms of outstanding stock: common stock and unvested restricted stock awards. Holders of unvested restricted stock awards receive non-forfeitable dividends at the same rate as common shareholders and they both share equally in undistributed earnings. Therefore, under the two-class method, the difference in EPS is not significant for these participating securities.
Recently Issued Accounting Standards | In January 2014, the FASB issued ASU No. 2014-04, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40) Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. Current accounting literature on troubled debt restructurings includes guidance on the receipt of one or more collateral assets in satisfaction of all or part of a receivable. The accounting literature indicates that a creditor should reclassify a collateralized mortgage loan such that the loan should be de-recognized and the collateral asset recognized when it is determined that there has been in substance a repossession or foreclosure by the creditor. However, in substance repossession or foreclosure and physical possession were not defined, leaving uncertainty about when a creditor should de-recognize the loan receivable and recognize the real estate property. This ASU clarifies when an in substance repossession or foreclosure occurs. ASU 2014-04 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014 for public entities. Since we currently do not hold any in substance foreclosures, the adoption of this ASU has not had any impact on our financial condition or results of operations. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The ASU is a converged standard involving FASB and International Financial Reporting Standards that provides a single comprehensive revenue recognition model for all contracts with customers across transactions and industries. The guidance in this ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. For public entities, the ASU is effective on a retrospective basis for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2016. Since this ASU does not apply to financial instruments and we do not have a significant source of non-interest income subject to this ASU, we do not expect it to have a significant impact on our financial condition or results of operations. In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation (Topic 718) Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. This ASU provides guidance for entities that grant their employees share-based payment awards where a performance target that affects vesting could be achieved after the requisite service period. That is the case when an employee is eligible to retire or otherwise terminate employment before the end of the period in which a performance target could be achieved and still be eligible to vest in the award if and when the performance target is achieved. This ASU stipulates that compensation expense should be recognized in the period where the performance target becomes probable of being achieved as opposed to the date that the award was granted. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. As of March 31, 2015 we have not granted share-based payment awards where a performance target that affects vesting could be achieved after the requisite service period. We do not expect this ASU to have a material impact on our financial condition or results of operations.
