Deliverables not within the scope of ASC 605-35 are evaluated for separation under ASC 605-25. For those elements falling under the guidance of ASC 605-25, we generally account for a deliverable (or a group of deliverables) separately if the delivered item(s) has standalone value to the customer and if we have given the customer a general right of return relative to the delivered item(s) and delivery or performance of the undelivered item(s) or service(s) is probable and substantially in our control.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">When items included in a multiple-element arrangement represent separate units of accounting, we allocate the arrangement consideration to the individual items based on their relative fair values.  The amount of arrangement consideration allocated to the delivered item(s) is limited to the amount not contingent on us delivering additional products or services.  Once we have determined the amount, if any, of arrangement consideration allocable to the delivered item(s), we apply the applicable revenue recognition policy to determine when and by which method such amount may be recognized as revenue.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We generally determine if objective and reliable evidence of fair value for the items included in a multiple-element arrangement exists based on whether we have vendor-specific objective evidence ("VSOE") of the price for which we sell an item on a standalone basis.  If we do not have VSOE for the item, we will use the price charged by a competitor selling a comparable product or service on a standalone basis to similarly situated customers, if available. If neither VSOE nor third party evidence is available, we use our best estimate of the selling price for that deliverable.</font></div></div>

Changes in estimates are reflected in the periods in which they become known.</font></div></div>
