This statement addresses (1) the effects on certain provisions on existing accounting standards as a result of the elimination of the qualifying special-purpose entity concept and (2) constituent concerns about the application of certain key provisions of existing accounting standards, including those in which the accounting and disclosures under existing accounting standards do not always provide timely and useful information about an enterprise’s involvement in a variable interest entity. This standard is effective for periods beginning after November 15, 2009. The adoption of this standard did not have a material effect on the Company’s financial position, results of operations or cash flows.   In January 2010, the Company adopted a newly issued accounting standard which requires additional disclosure about the amounts of and reasons for significant transfers in and out of Level 1 and Level 2 fair-value measurements. This standard also clarifies existing disclosure requirements related to the level of disaggregation of fair value measurements for each class of assets and liabilities and disclosure about inputs and valuation techniques used to measure fair value for both recurring and nonrecurring Level 2 and Level 3 measurements. As this newly issued accounting standard only requires enhanced disclosure, the adoption of this standard did not impact the Company’s financial position or results of operations. In addition, effective for interim and annual period beginning after December 15, 2010, this standard will require additional disclosure and require an entity to present disaggregated information about activity in Level 3 fair-value measurements on a gross basis, rather than as one net amount.   Recently Issued Accounting Standards   In October 2009, a new accounting consensus was issued for multiple-deliverable revenue arrangements. This consensus amends existing revenue recognition accounting standards. This consensus provides accounting principles and application guidance on whether multiple deliverables exist, how the arrangement should be separated and the consideration allocated. This guidance eliminates the requirement to establish the fair value of undelivered products and services and instead provides for separate revenue recognition based upon management’s estimate of the selling price for an undelivered item when there is no other means to determine the fair value of that undelivered item.  Previously, the existing accounting consensus required that the fair value of the undelivered item be the price of the item either sold in a separate transaction between unrelated third parties or the price charged for each item when the item is sold separately by the vendor. Under the existing accounting consensus, if the fair value of all of the elements in the arrangement was not determinable, then revenue was deferred until all of the items were delivered or fair value was determined. This new approach is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. The Company is in the process of evaluating whether the adoption of this standard will have a material effect on its financial position, results of operations or cash flows.   In October 2009, a new accounting consensus was issued for certain revenue arrangements that include software elements. This consensus amends the existing accounting guidance for revenue arrangements that contain tangible products and software. This consensus requires that tangible products which contain software components and non-software components that function together to deliver the tangible products essential functionality are no longer within the scope of the software revenue guidance. This new approach is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. The Company is in the process of evaluating whether the adoption of this standard will have a material effect on its financial position, results of operations or cash flows. </div> </div></div> 13 Recent Accounting Standard Changes and Developments   Recently Adopted Accounting Standards   In June 2009, a new accounting standard was false false false Represents disclosure of any changes in an accounting principle, including a change from one generally accepted accounting principle to another generally accepted accounting principle when there are two or more generally accepted accounting principles that apply or when the accounting principle formerly used is no longer generally accepted.
