	us-gaap	Description Of New Accounting Pronouncements Not Yet Adopted DescriptionOfNewAccountingPronouncementsNotYetAdopted	<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Accounting Pronouncements Recently Issued</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-15, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.</font><font style="font-family:inherit;font-size:10pt;"> The Update provides U.S. GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of ASU No. 2014-12 is not expected to have a material impact on the Company’s consolidated financial statements.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In June 2014, the FASB issued ASU No. 2014-12,</font><font style="font-family:inherit;font-size:10pt;font-style:italic;"> Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Services Period</font><font style="font-family:inherit;font-size:10pt;">. The Update provides guidance for determining compensation cost under specific circumstances when an employee is eligible to vest in an award regardless of whether the employee is rendering service on the date the performance target is achieved. ASU 2014-12 becomes effective for annual and interim periods beginning after December 15, 2015 with early adoption permitted. As of September 30, 2014, the Company did not have any share-based payment awards that include performance targets that could be achieved after the requisite service period. As such, the adoption of ASU No. 2014-12 is not expected to have a material impact on the Company’s consolidated financial statements.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In June 2014, the FASB issued ASU 2014-11, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures</font><font style="font-family:inherit;font-size:10pt;">. The Update changes the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with accounting for other repurchase agreements. Additionally, the amendment requires new disclosures on transfers accounted for as sales in transactions that are economically similar to repurchase agreements and requires increased transparency on collateral pledged in secured borrowings. The amendments in this update will be effective for the first interim or annual period beginning after December 31, 2014, with the exception of the collateral disclosures which will be effective for interim periods beginning after March 15, 2015. Early application is not permitted. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements, but does not expect the guidance to have a material impact on the Company’s consolidated financial statements.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In May 2014, the FASB issued ASU 2014-04 No. 2014-09, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Revenue from Contracts with Customers</font><font style="font-family:inherit;font-size:10pt;">. The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the codification. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2016. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements, but does not expect the guidance to have a material impact on the Company’s consolidated financial statements.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In April 2014, the the FASB issued ASU No. 2014-08, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. </font><font style="font-family:inherit;font-size:10pt;">The Update raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. The Company is assessing the impact of the new guidance on its consolidated financial statements.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In January 2014, the FASB issued ASU 2014-04, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure</font><font style="font-family:inherit;font-size:10pt;">. The Update clarifies when a creditor would be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that all or a portion of the loan would be derecognized and the real estate property recognized. Under the guidance, a consumer loan collateralized by residential real estate should be reclassified to other real estate owned when (1) the creditor obtains legal title to the residential property or (2) the borrower conveys all interest in the property to the creditor to satisfy the loan by completing a deed in lieu of foreclosure or similar agreement. In addition, an entity is required to disclose the amount of residential real estate meeting the conditions above, and the recorded investment in consumer mortgage loans secured by residential real estate that are in the process of foreclosure. ASU 2014-04 is effective for annual and interim reporting periods within those annual periods, beginning after December 15, 2014. Adoption of the new guidance is not expected to have a significant impact on the Company’s consolidated financial statements. </font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In January 2014, the FASB issued ASU No. 2014-01, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Accounting for Investments in Qualified Affordable Housing Projects.</font><font style="font-family:inherit;font-size:10pt;"> The Update provides guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit. The amendments in this Update permit the reporting entity to make an accounting policy election to account for its investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, the cost of the investment is amortized each reporting period in proportion to the tax credits received. Under the new guidance, classification of the amortization would change from noninterest expense to income tax expense. ASU 2014-01 is effective for annual and interim reporting periods within those annual periods, beginning after December 15, 2014. The guidance is to be applied retrospectively to all periods presented. The Company has assessed the impact of the new guidance and determined that adopting the proportional amortization method will not have a material impact on its consolidated financial statements.</font></div></div>
