       In October 2009, the FASB issued a revised accounting standard
       for revenue arrangements with multiple deliverables. The
       revision: (1)&amp;#160;removes the
       &lt;font style="white-space: nowrap"&gt;objective-and-reliable-evidence-of-fair-value&lt;/font&gt;
       criterion from the separation criteria used to determine whether
       an arrangement involving multiple deliverables contains more
       than one unit of accounting, (2)&amp;#160;provides a hierarchy that
       entities must use to estimate the selling price,
       (3)&amp;#160;eliminates the use of the residual method for
       allocation, and (4)&amp;#160;expands the ongoing disclosure
       requirements. The revised accounting standard is effective for
       the Company beginning on January&amp;#160;1, 2011, with early
       adoption permitted. The Company is currently assessing the
       impact the revised accounting standard will have on its
       consolidated financial statements.

       In October 2009, the FASB issued a revised accounting standard
       for certain revenue arrangements that include software elements.
       Under the revised standard, tangible products that contain both
       software and non-software components that work together to
       deliver a product&amp;#8217;s essential functionality will be removed
       from the scope of pre-existing software revenue recognition
       standards. In addition, hardware components of a tangible
       product containing software components will always be excluded
       from software revenue recognition standards. The revised
       accounting standard is effective for the Company beginning on
       January&amp;#160;1, 2011, with early adoption permitted. The Company
       is currently assessing the impact the revised accounting
       standard will have on its consolidated financial statements.
