Contract costs include all direct material, manufacturing, project management, engineering labor, subcontracting and indirect costs related to contract design, production, integration, installation, delivery of all performance obligations, and any warranty reserve.  Indirect costs include allocated charges for such items as facilities, equipment depreciation, and general overhead.  Provisions for estimated losses on uncompleted contracts are made in the period such losses are capable of being estimated.  Generally, construction-type contracts we enter into have fixed prices established, and to the extent the actual costs to complete construction-type contracts are higher than the amounts estimated as of the date of the financial statements, the resulting gross margin would be negatively affected in future quarters when we revise our estimates.  Our policy and practice is to revise estimates as soon as such changes in estimates are known. We combine contracts for accounting purposes when they are negotiated as a package with an overall profit margin objective, essentially represent an agreement to do a single project for a customer, involve interrelated construction activities, and are performed concurrently or sequentially.  When we combine a group of contracts, revenue and profit are recognized uniformly over the performance of the combined projects.  We segment revenues in accordance with the contract segmenting criteria in ASC 605-35, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Construction-Type and Production-Type Contracts.</font></div></div>

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>

Estimation processes are also used in inventory valuation, the allowance for doubtful accounts, share-based compensation, goodwill impairment, and extended warranty and product maintenance agreements. Changes in estimates are reflected in the periods in which they become known.</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>
