New Accounting Pronouncements	(11) New Accounting Pronouncements ASU 2011-02, Receivables (Topic 310): A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring was issued to clarify the accounting principles applied to loan modifications, as defined by FASB ASC Subtopic 310-40, Receivables – Troubled Debt Restructurings by Creditors. The increased volume in loan modifications, which resulted from the recent economic downturn, prompted this guidance. The Update clarifies guidance on a creditor’s evaluation of whether or not a concession has been granted, with an emphasis on evaluating all aspects of the modification rather than a focus on specific criteria, such as the effective interest rate test, to determine a concession. The Update provides guidance on specific types of modifications, such as changes in the interest rate of the borrowing, and insignificant delays in payments, as well as guidance on the creditor’s evaluation of whether or not a debtor is experiencing financial difficulties. For public entities, the amendments in the Update are effective for the first interim or annual periods beginning on or after June 15, 2011, and should be applied retrospectively to the beginning of the annual period of adoption. The entity should also disclose information required by ASU 2010-20, Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses, which had previously been deferred by ASU 2011-01, Deferral of the Effective Date of Disclosures about Troubled Debt Restructurings in Update No. 2010-20, for interim and annual periods beginning on or after June 15, 2011. Early adoption is permitted. The adoption of this update requires the Company to provide additional disclosures related to troubled debt restructurings. In April 2011, the FASB issued ASU 2011-03, Transfers and Servicing (Topic 860): Reconsideration of Effective Control for Repurchase Agreements to improve the accounting for repurchase agreements (“repos”) and other agreements that both entitle and obligate a transferor to repurchase or redeem financial assets before their maturity. During the global economic crisis, capital market participants questioned the necessity and usefulness of the collateral maintenance guidance for the transferor’s ability criterion (described below) when determining whether a repo should be accounted for as a sale or as a secured borrowing. In a typical repo transaction, an entity transfers financial assets to a counterparty in exchange for cash with an agreement for the counterparty to return the same or equivalent financial assets for a fixed price in the future. Topic 860, Transfers and Servicing, prescribes when an entity may or may not recognize a sale upon the transfer of financial assets subject to repurchase agreements. That determination is based, in part, on whether the entity has maintained effective control over the transferred financial assets. The guidance in this Update is effective for the first interim or annual period beginning on or after December 15, 2011. The guidance 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 update may require the Company to provide additional disclosures related to repos. In May 2011, the FASB issued ASU 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs as a result of the work by the FASB and the IASB to develop common requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. generally accepted accounting principles (GAAP) and International Financial Reporting Standards (IFRSs). The amendments in this Update explain how to measure fair value. They do not require additional fair value measurements and are not intended to establish valuation standards or affect valuation practices outside of financial reporting. For many of the requirements, the Board does not intend for the amendments in this Update to result in a change in the application of the requirements in Topic 820. The amendments in this Update are to be applied prospectively. For public entities, the amendments are effective during interim and annual periods beginning after December 15, 2011. For nonpublic entities, the amendments are effective for annual periods beginning after December 15, 2011. Early application by public entities is not permitted. Nonpublic entities may apply the amendments in this Update early, but no earlier than for interim periods beginning after December 15, 2011. The adoption of this update may require the Company to provide additional disclosures related to fair value measurements. In June 2011, the FASB issued ASU 2011-05—Comprehensive Income (Topic 220): Presentation of Comprehensive Income was issued 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. generally accepted accounting principles (GAAP) and International Financial Reporting Standards (IFRS), the FASB decided to eliminate the option to present components of other comprehensive income as part of the statement of changes in shareholders’ equity, among other amendments in this Update. The amendments require that all nonowner changes in shareholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments in this Update should be applied retrospectively. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. Early adoption is permitted, because compliance with the amendments is already permitted. The amendments do not require any transition disclosures. The adoption of this update will require the Company to provide a change in disclosures related to other comprehensive income.
