In October 2009, the FASB issued an update to the revenue recognition topic of the Codification.  The update addresses the accounting for multiple-deliverable arrangements to enable vendors to account for products or services (deliverables) separately rather than as a combined unit. This guidance establishes a selling price hierarchy for determining the selling price of a deliverable, which is based on: (a) vendor-specific objective evidence; (b) third-party evidence; or (c) estimates. This guidance also eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. In addition, this guidance significantly expands required disclosures related to a vendor's multiple-deliverable revenue arrangements. The update 2009-13 is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010 and early adoption is permitted.  The adoption of this standard did not have a material impact on our consolidated condensed financial statements.

In April 2010, the FASB issued additional guidance for revenue recognition to provide criteria that should be met for determining whether the milestone method of revenue recognition is appropriate. A vendor can recognize as revenue, in its entirety, consideration that is contingent upon achievement of a milestone in the period in which the milestone is achieved only if the milestone meets all criteria to be considered substantive. The guidance for milestone method of revenue recognition is effective on a prospective basis for milestones achieved in fiscal years, and interim periods within those years, beginning on or after June 15, 2010.  The adoption of this standard did not have a material impact on our consolidated condensed financial statements.

In January 2010, the FASB issued an update which provides guidance to improve disclosures about fair value measurements. This guidance amends previous guidance on fair value measurements to add new requirements for disclosures about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurement on a gross basis rather than on a net basis as previously required. This update also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value. This guidance is effective for annual and interim periods beginning after December 15, 2009, except for the requirement to provide the Level 3 activities of purchases, sales, issuances, and settlements on a gross basis, which will be effective for annual and interim periods beginning after December 15, 2010. Early application is permitted and, in the period of initial adoption, entities are not required to provide the amended disclosures for any previous periods presented for comparative purposes. This update did not have a material impact on our consolidated condensed financial statements.

In March 2010, the FASB issued an update to clarify that an employee share-based payment award with an exercise price denominated in the currency of a market in which a substantial portion of the equity securities trades should not be considered to contain a condition that is not a market, performance, or service condition. Therefore, an entity would not classify an award with such a feature as a liability if it otherwise qualifies as equity. Affected entities are required to record a cumulative catch-up adjustment for all awards outstanding as of the beginning of the annual period in which the guidance is adopted. This update did not have a material impact on our consolidated condensed financial statements.
