Recent Accounting Pronouncements	NOTE 2 Recent Accounting Pronouncements *Recently Adopted Accounting Pronouncements* In December 2010, the Financial Accounting Standards Board (FASB) issued additional guidance applicable to the testing of goodwill for potential impairment. Specifically, for reporting units with zero or negative carrying amounts, an entity is required to perform the second step of the goodwill impairment test (a comparison between the carrying amount of a reporting unit’s goodwill to its implied fair value) if it is more likely than not that a goodwill impairment exists, considering any adverse qualitative factors. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2010.

In October 2009, the FASB issued amended guidance on the accounting for revenue arrangements that contain multiple elements by eliminating the criteria that objective and reliable evidence of fair value for undelivered products or services needs to exist in order to be able to account separately for deliverables and eliminating the use of the residual method of allocating arrangement consideration. The amendments establish a hierarchy for determining the selling price of a deliverable and will allow for the separation of products and services in more instances than previously permitted. We adopted the new multiple element guidance effective January 1, 2011 for new arrangements entered into or arrangements materially modified on or after that date on a prospective basis. The adoption of the new multiple element guidance did not result in a material change in either the units of accounting or the pattern or timing of revenue recognition. Additionally, the adoption of the revised multiple element arrangement guidance did not have a material impact on our financial position, results of operations or cash flows. In October 2009, the FASB amended the accounting requirements for software revenue recognition. The objective of this update is to address the accounting for revenue arrangements that contain tangible products and software. Specifically, products that contain software that is “more than incidental” to the product as a whole will be removed from the scope of the software revenue recognition literature. The amendments align the accounting for these revenue transaction types with the amendments described for multiple element arrangements above. We adopted the provisions of this guidance for new or materially modified arrangements entered into on or after January 1, 2011 on a prospective basis. The adoption of this guidance did not have a material impact on our financial position, results of operations or cash flows. *Accounting Pronouncements Not Yet Adopted* In September 2011, the FASB provided companies with the option to make an initial qualitative evaluation, based on the entity’s events and circumstances, to determine the likelihood of goodwill impairment. The result of this qualitative assessment determines whether it is necessary to perform the currently required two-step impairment test. If it is more likely than not that the fair value of a reporting unit is less than its carrying amount, a company would be required to perform the two-step impairment test. This guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company could elect to apply the option in future goodwill impairment tests; however, the amendments are not expected to have a material effect on the Company’s Consolidated Financial Statements. In May 2011, the FASB issued guidance intended to achieve common fair value measurements and related disclosures between U.S. GAAP and international accounting standards. The amendments primarily clarify existing fair value guidance and are not intended to change the application of existing fair value measurement guidance. However, the amendments include certain instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed. This guidance is effective for the periods beginning after December 15, 2011 and early application is prohibited. We will adopt these amendments on January 1, 2012; however, the requirements are not expected to have a material effect on the Company’s Consolidated Financial Statements.
