IMPACT OF ACCOUNTING STANDARDS AND INTERPRETATIONS [Abstract]
New Accounting Pronouncement, Early Adoption [Table Text Block]	IMPACT OF ACCOUNTING STANDARDS AND INTERPRETATIONS Accounting Standard Update (“ASU”) No. 2010-06 under ASC Topic 820, “Fair Value Measurements and Disclosures,” requires new disclosures and clarifies certain existing disclosure requirements about fair value measurement. Specifically, the update requires an entity to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for such transfers. A reporting entity is required to present separately information about purchases, sales, issuances, and settlements in the reconciliation of fair value measurements using Level 3 inputs. In addition, the update clarifies the following requirements of the existing disclosures: (i) for the purposes of reporting fair value measurement for each class of assets and liabilities, a reporting entity needs to use judgment in determining the appropriate classes of assets; and (ii) a reporting entity is required to include disclosures about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements. The disclosures related to the gross presentation of purchases, sales, issuances and settlements of assets and liabilities included in Level 3 of the fair value hierarchy were adopted by 'The Company' on January 1, 2011. The remaining disclosure requirements and clarifications made by ASU No. 2010-06 became effective for 'the Company' on April 1, 2010. In May 2011, the FASB issued guidance which results in common principles and requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. GAAP and International Financial Reporting Standards. This guidance is to be applied prospectively and is effective during interim and annual periods beginning after December 15, 2011. Early application is not permitted. The adoption of this guidance is not expected to have a material effect on the Company's consolidated statement of condition or results of operations. ASU No. 2010-18, “Receivables (Topic 310)-Effect of a Loan Modification When the Loan Is Part of a Pool That Is Accounted for as a Single Asset,” codifies the consensus reached by the Emerging Issues Task Force (“EITF”) that modifications of loans that are accounted for within a pool under ASC Subtopic 310-30 do not result in the removal of those loans from the pool even if the modification of those loans would otherwise be considered a troubled debt restructuring. An entity will continue to be required to consider whether the pool of assets in which the loan is included is impaired if expected cash flows for the pool change. ASU No. 2010-18 does not affect the accounting for loans under the scope of Subtopic 310-30 that are not accounted for within pools. Loans accounted for individually under Subtopic 310-30 continue to be subject to the troubled debt restructuring accounting provisions within Subtopic 310-40. ASU No. 2010-18 is effective prospectively for modifications of loans accounted for within pools under Subtopic 310-30 occurring in the first interim or annual period ending on or after July 15, 2010. Early application is permitted. Upon initial adoption of ASU No. 2010-18, an entity may make a one-time election to terminate accounting for loans as a pool under Subtopic 310-30. This election may be applied on a pool-by-pool basis and does not preclude an entity from applying pool accounting to subsequent acquisitions of loans with evidence of credit deterioration. The new guidance did not to have a material impact on the Company's consolidated financial statements. In July 2010, the FASB issued guidance related to disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses, ASU No. 2010-20, Receivables (Topic 310) which requires significant new disclosures about the credit quality of financing receivables and the allowance for credit losses. The objective of these disclosures is to improve financial statement users' understanding of (i) the nature of an entity's credit risk associated with its financing receivables and (ii) the entity's assessment of that risk in estimating its allowance for credit losses as well as changes in the allowance and the reasons for those changes. The disclosures are to be presented at the level of disaggregation that management uses when assessing and monitoring the portfolio's risk and performance. The required disclosures include, among other things, a roll forward of the allowance for credit losses as well as information about modified, impaired, non-accrual and past due loans and credit quality indicators. ASU No. 2010-20 disclosures related to period-end information (e.g., credit-quality information and the ending financing receivables balance segregated by impairment method) were required in all interim and annual reporting periods ending on or after December 15, 2010. Disclosures of activity that occurs during a reporting period (e.g., modifications and the roll forward of the allowance for credit losses by portfolio segment) were required in interim or annual periods beginning on or after December 15, 2010. The required disclosures for the period have been included in footnote 5 to the financial statements. In June 2009, the FASB issued guidance on Variable Interest Entities (“VIE”) (ASC Subtopic 860-10) (formerly Statement of Financial Accounting Standards (“SFAS”) No. 167), which amended the previous guidance applicable to VIE's and changed how a reporting entity determines when an entity that is insufficiently capitalized or is not controlled through voting (or similar rights) should be consolidated. ASC Subtopic 860-10 requires reporting entities to evaluate former qualifying special purpose entities for consolidation, changes the approach to determining a variable interest entity's primary beneficiary, increases the frequency of required assessments to determine whether a company is the primary beneficiary of a VIE, clarifies the characteristics that identify a VIE, and requires additional annual and interim disclosures. This standard is effective for fiscal years beginning after November 15, 2009. The Company adopted this guidance on April 1, 2010 and there was no material impact on the Company's financial condition, results of operations or financial statement disclosures. In June 2009, the FASB issued a revision to earlier guidance on Transfers of Financial Assets (ASC Subtopic 860-10) (formerly SFAS No. 166), which eliminates the concept of a “qualifying special-purpose entity”, changes the requirements for derecognizing financial assets and includes additional disclosures requiring more information about transfers of financial assets in which entities have continuing exposure to the risks related to the transferred financial assets. This guidance must be applied as of the beginning of each reporting entity's first annual reporting period that begins after November 15, 2009, for interim periods within the first annual reporting period and for interim and annual reporting periods thereafter. Earlier application was prohibited. The Company adopted this guidance for transfers of financial assets on April 1, 2010 and there was no material effect on its consolidated financial statements. In April 2011, the FASB issued a revision to earlier guidance for accounting for troubled debt restructurings (ASU 2011-02). The ASU clarifies the guidance on a creditor's evaluation of whether it has granted a concession and whether a debtor is experiencing financial difficulties, such as: •Creditors cannot assume that debt extensions at or above a borrower's original contractual rate do not constitute troubled debt restructurings. •If a borrower doesn't have access to funds at a market rate for debt with characteristics similar to the restructured debt, that may indicate that the creditor has granted a concession. •A borrower that is not currently in default may still be considered to be experiencing financial difficulty when payment default is considered probable in the foreseeable future. The guidance will be effective for the for interim and annual periods ending on or after June 15, 2011 and is to be applied retrospectively to restructurings occurring on or after April 1, 2011. The Company is currently evaluating the potential impact of adopting the ASU. In May 2009, the FASB issued guidance related to Subsequent Events (ASC Subtopic 855-10) (formerly SFAS No. 165) which established general standards of accounting for and disclosures of events that occur after the balance sheet date but before financial statements are issued. Specifically, this standard sets forth the period after the balance sheet date during which management should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements, the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements and the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. Carver has evaluated subsequent events for potential recognition and/or disclosure through the date the consolidated financial statements included in this Form 10-Q were issued. In April 2011, the FASB issued guidance to improve financial reporting of repurchase agreements and other agreements that both entitle and obligate a transferor to repurchase or redeem financial assets before their maturity. The amendments to this guidance remove from the assessment of effective control: (1) the criterion requiring the transferor to have the ability to repurchase or redeem the financial assets on substantially the agreed terms, even in the event of default by the transferee, and (2) the collateral maintenance implementation guidance related to that criterion. Other criteria applicable to the assessment of effective control are not changed by this new guidance. Those criteria indicate that the transferor is deemed to have maintained effective control over the financial assets transferred (and thus must account for the transaction as a secured borrowing) for agreements that both entitle and obligate the transferor to repurchase or redeem the financial assets before their maturity if all of the following conditions are met: (1) the financial assets to be repurchased or redeemed are the same or substantially the same as those transferred; (2) the agreement is to repurchase or redeem them before maturity, at a fixed or determinable price; and (3) the agreement is entered into contemporaneously with, or in contemplation of, the transfer. This guidance is effective for the first interim or annual period beginning on or after December 15, 2011, and should be applied prospectively to transactions or modifications of existing transactions that occur on or after the effective date. Early adoption is not permitted. The adoption of this guidance is not expected to have a material effect on the Company's consolidated statement of condition or results of operations. In June 2011, the Financial Accounting Standards Board (“FASB”) issued guidance regarding the presentation of comprehensive income. Under this guidance, 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. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. This guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. It does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and should be applied retrospectively. The Company is currently evaluating the potential impact of adopting the ASU.
