New Accounting Standards and Accounting Changes [Abstract]
New Accounting Standards and Accounting Changes	2. New Accounting Standards and Accounting Changes *Changes in Accounting Policies* In October 2009, the FASB issued ASU No. 2009-13, “Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements (a consensus of the FASB Emerging Issues Task Force)” (“ASU 2009-13”) which amends ASC 605-25, “Revenue Recognition: Multiple-Element Arrangements.” ASU 2009-13 addresses how to determine whether an arrangement involving multiple deliverables contains more than one unit of accounting and how to allocate consideration to each unit of accounting in the arrangement. This ASU removes the fair value criteria for determining separate units of accounting and replaces all references to fair value as the measurement criteria with the term selling price and establishes a hierarchy for determining the selling price of a deliverable. Consideration in a multiple-element arrangement is allocated at the inception of the arrangement to all deliverables on the basis of the relative selling price. When applying the relative selling price method, the selling price for each deliverable is determined using vendor-specific objective evidence (“VSOE”) of the selling price, or third-party evidence (“TPE”) of the selling price. If neither VSOE nor TPE of the selling price exists for a deliverable, the Company will use its best estimate of the selling price (“BESP”) for that deliverable. ASU No. 2009-13 also eliminates the use of the residual value method for determining the allocation of arrangement consideration. Additionally, ASU 2009-13 requires expanded disclosures and is effective for fiscal years beginning on or after June 15, 2010. On January 1, 2011, the Company adopted the accounting requirements in ASU 2009-13 prospectively for revenue arrangements entered into or materially modified after the date of adoption. As described below, the adoption of these updates did not have, nor are they expected to have, a material effect on the Company’s financial condition or results of operations. The amended standard with respect to multiple-element arrangements is not expected to materially change the allocation of arrangement consideration to the Company’s units of accounting. The pattern and timing of revenue recognition for those arrangements entered into or materially modified after the date of adoption may be affected as a result of the adoption of the amended ASC 605-25 requirements. The Company will be required to develop a selling price for each deliverable using VSOE, TPE or BESP and allocate consideration amongst deliverables and to recognize revenue using that allocated consideration for the delivered units of accounting in the current period. For arrangements entered into or modified prior to the adoption date, the Company defers all consideration received and receivable under arrangements for which the selling price of an undelivered item has not yet been established. In October 2009, the FASB issued ASU No. 2009-14, “Software (Topic 985): Certain Revenue Arrangements That Include Software Elements (a consensus of the FASB Emerging Issues Task Force)” (“ASU 2009-14”). ASU 2009-14 amends ASC 985-605, “Software: Revenue Recognition,” such that tangible products, containing both software and non-software components that function together to deliver the tangible product’s essential functionality, are no longer within the scope of ASC 985-605. It also amends the determination of how arrangement consideration should be allocated to deliverables in a multiple-deliverable revenue arrangement. The amendments in this update are effective, on a prospective basis, for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. On January 1, 2011, the Company adopted the accounting requirements in ASU 2009-14. The application of this amended standard does not have an impact on the Company’s condensed consolidated financial statements. In January 2010, the FASB issued ASU No. 2010-06, “Improving Disclosures about Fair Value Measurements,” (“ASU 2010-06”) to amend topic ASC 820 “Fair Value Measurements and Disclosures,” by improving disclosure requirements in order to increase transparency in financial reporting. ASU 2010-06 requires that an entity disclose separately the amounts of significant transfers in and out of Levels 1 and 2 fair value measurements and describe the reasons for the transfers. Furthermore, an entity should present information about purchases, sales, issuances, and settlements for Level 3 fair value measurements. ASU 2010-06 also clarifies existing disclosures for the level of disaggregation and disclosures about input and valuation techniques. The new disclosures and clarifications of existing disclosures are effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances, and settlements for the activity in Level 3 fair value measurements. Those disclosures are effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. On January 1, 2010, the Company adopted the disclosure amendments in ASU 2010-06, except for the amendments to Level 3 fair value measurements as described above, and has expanded disclosures as presented in Note 17. On January 1, 2011, the Company adopted the disclosure amendments in ASU 2010-06 pertaining to Level 3 fair value measurements and has expanded disclosures as presented in note 17(b). In July 2010, the FASB issued ASU No. 2010-20, “Receivables (Topic 310): Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses” (“ASU 2010-20”). The objective of ASU 2010-20 is to provide financial statement users with greater transparency about an entity’s allowance for credit losses and the credit quality of its financing receivables. Under ASU 2010-20, an entity is required to provide disclosures so that financial statement users can evaluate the nature of the credit risk inherent in the entity’s portfolio of financing receivables, how that risk is analyzed and assessed to arrive at the allowance for credit losses, and the changes and reasons for those changes in the allowance for credit losses. ASU 2010-20 is applicable to all entities with financing receivables, excluding short-term trade accounts receivable or receivables measured at fair value or lower of cost or fair value. It is effective for interim and annual reporting periods ending on or after December 15, 2010. Comparative disclosures are required to be disclosed for those reporting periods ending after initial adoption. On December 31, 2010, the Company adopted the disclosure requirements in ASU 2010-20 and has expanded disclosures as presented in note 17(c). In December 2010, the FASB issued ASU No. 2010-28, “Intangibles — Goodwill and Other (Topic 350): When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts” (“ASU 2010-28”). The objective of ASU 2010-28 is to address questions about entities with reporting units with zero or negative carrying amounts. The amendments in ASU 2010-28 modify Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists by considering whether there are any adverse qualitative factors indicating that an impairment may exist. ASU 2010-28 is applicable to all entities that have recognized goodwill and have one or more reporting units whose carrying amount for purposes of performing Step 1 of the goodwill impairment test is zero or negative. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. On January 1, 2011, the Company adopted the accounting requirements in ASU 2010-28. This amended standard does not have an impact on the Company’s condensed consolidated financial statements at this time as the Company does not have any reporting units with zero or negative amounts for goodwill impairment testing purposes. In January 2011, the FASB issued ASU No. 2011-01, “Receivables (ASC Topic 310): Deferral of the Effective Date of Disclosures about Troubled Debt Restructuring in Update No. 2010-20 (“ASU 2011-01”) which delays the effective date of disclosure requirements for troubled debt restructurings in ASU 2010-20 for public entities. This guidance is effective immediately. The adoption of ASU 2011-01 did not have a material impact on the Company’s condensed consolidated financial statements. *Recently Issued FASB Accounting Standard Codification Updates* In April 2011, the FASB issued ASU No. 2011-02, “Receivables (ASC Topic 310): A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring in Update No 2010-20” (“ASU 2011-02”). ASU 2011-02 clarifies which loan modifications constitute troubled debt restructurings and is intended to assist creditors in determining whether a modification of the terms of a receivable meets the criteria to be considered a troubled debt restructuring, both for purposes of recording an impairment loss and for disclosure of troubled debt restructurings. In evaluating whether a restructuring constitutes a troubled debt restructuring, a creditor must separately conclude, under the guidance clarified by ASU 2011-02, that both of the following exist: (a) the restructuring constitutes a concession; and (b) the debtor is experiencing financial difficulties. For public entities, the amendments in ASU 2011-02 are effective for the first interim or annual period beginning on or after June 15, 2011, with retrospective application to the beginning of the annual period of adoption. Early application by public entities is not permitted. The amendments in ASU 2011-02 do not have an impact on the Company’s condensed consolidated financial statements. In May 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurement (ASC Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (“ASU 2011-04”). The standards set forth in ASU 2011-04 supersede most of the accounting guidance currently found in Topic 820 of the FASB’s ASC. The amendments will improve comparability of fair value measurements presented and disclosed in financial statements prepared with GAAP and International Financial Reporting Standards (“IFRS”). The amendments also clarify the application of existing fair value measurement requirements. These amendments include (1) the application of the highest and best use and valuation premise concepts, (2) measuring the fair value of an instrument classified in a reporting entity’s shareholders’ equity and (3) disclosing quantitative information about the unobservable inputs used within the Level 3 hierarchy. For public entities, the amendments are effective for interim and annual periods beginning after December 15, 2011 on a prospective basis. Early application by public entities is not permitted. The Company is currently evaluating the potential impact of ASU 2011-04 on its condensed consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (“ASU 2011-05”). The amendments contained within this update 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, eliminating the option to present the components of other comprehensive income as part of the statement of changes in shareholders’ equity. The objective of this amendment is to improve the comparability, consistency, and transparency of financial reporting and to increase the prominence of items reported in other comprehensive income. For public entities, the amendments are effective for interim and annual periods beginning after December 15, 2011, on a retrospective basis. Early application by public entities is permitted. The Company is currently evaluating the potential impact of ASU 2011-05 on its condensed consolidated financial statements.
