K. Recently Adopted Accounting Pronouncements

In October 2009, the FASB issued a new accounting standard which provides guidance for arrangements with multiple deliverables which are not within the scope of the current software revenue recognition guidance. Specifically, the new standard requires an entity to allocate consideration at the inception of an arrangement to all of its deliverables based on their relative selling prices. In the absence of VSOE or third-party evidence of the selling prices, consideration must be allocated to the deliverables based on management's best estimate of the selling prices. In addition, the new standard eliminates the use of the residual method of allocation. In October 2009, the FASB also issued a new accounting standard which changes revenue recognition for tangible products containing software and hardware elements. Specifically, tangible products containing software and hardware that function together to deliver the tangible products' essential functionality are scoped out of the existing software revenue recognition guidance and will be accounted for under the multiple-element arrangements revenue recognition guidance discussed above. Both standards were effective for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010 with early adoption permitted. We adopted the new guidance as of May 1, 2011 and it did not have a material impact on our results of operations for the three months ended July 31, 2011.
