We provide flexible application software and modular, multifunction hardware that users combine with industry-standard computers, networks and third party devices to create measurement, automation and embedded systems, which we also refer to as &#8220;virtual instruments.&#8221; Our approach gives customers the ability to quickly and cost-effectively design, prototype and deploy unique custom-defined solutions for their design, control and test application needs. We offer hundreds of products used to create virtual instrumentation systems for general, commercial, industrial and scientific applications. Our products may be used in different environments, and consequently, specific application of our products is determined by the customer and generally is not known to us. We approach all markets with essentially the same products, which are used in a variety of applications from research and development to production testing, monitoring and industrial control. The following industries and applications are served by us worldwide: advanced research, automotive, commercial aerospace, computers and electronics, continuous process manufacturing, education, government/defense, medical research/pharmaceutical, power/energy, semiconductors, automated test equipment, telecommunications and others.

Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management.

Unrealized losses are charged against income when a decline in fair value is determined to be other than temporary. Investments with maturities beyond one year are classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. The fair value of our short-term investments in debt securities at December 31, 2010 and December 31, 2009 was $131 million and $87 million, respectively. The increase was due to the net purchase of $44 million of short-term investments which was done to continue the diversification our holdings from money market accounts to debt securities and to take advantage of higher yields associated with longer maturity debt securities. We follow the guidance provided by FASB ASC 320 to assess whether our investments with unrealized loss positions are other than temporarily impaired. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in other income (expense), net, in our Consolidated Statements of Income. We did not identify or record any other-than-temporary impairments during 2010&#160;or 2009.</font></div><div style="TEXT-INDENT: 0pt; DISPLAY: block"><br /></div><div style="TEXT-INDENT: 9pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"><font style="FONT-STYLE: italic; DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">Accounts Receivable, net</font></div><div style="TEXT-INDENT: 0pt; DISPLAY: block"><br /></div><div style="TEXT-INDENT: 27pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">Accounts receivable are recorded net of allowances for sales returns of $1.7 million and $1.9 million at December 31, 2010 and 2009, respectively, and net of allowances for doubtful accounts of $2.1 million and $2.7 million at December 31, 2010 and 2009, respectively. A provision for estimated sales returns is made by reducing recorded revenue based on historical experience. We analyze historical returns, current economic trends and changes in customer demand of our products when evaluating the adequacy of our sales returns allowance.

Undelivered elements for our multiple element arrangements with a customer are generally restricted to post contract support and training and education. The amount of revenue allocated to these undelivered elements is based on the VSOE of fair value for those undelivered elements. Deferred revenue due to undelivered elements is recognized ratably over the service period or when the service is completed. When VSOE of fair value is not available for the undelivered element of a multiple element arrangement, sales revenue for the entire sales contract value is generally recognized ratably over the service period of the undelivered element, generally 12 months or when the service is completed in accordance with the subscription method. Deferred revenue at December 31, 2010 and 2009 was $72 million and $57 million, respectively.</font></div><div style="TEXT-INDENT: 0pt; DISPLAY: block"><br /></div><div style="TEXT-INDENT: 27pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">The application of FASB ASC 985 requires judgment, including whether a software arrangement includes multiple elements, and if so, whether VSOE of fair value exists for those elements. Changes to the elements in a software arrangement, the ability to identify VSOE for those elements, the fair value of the respective elements, and changes to a product&#8217;s estimated life cycle could materially impact the amount of our earned and unearned revenue. Judgment is also required to assess whether future releases of certain software represent new products or upgrades and enhancements to existing products.</font></div><div style="TEXT-INDENT: 0pt; DISPLAY: block"><br /></div><div style="TEXT-INDENT: 9pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"><font style="FONT-STYLE: italic; DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">Product revenue</font></div><div style="TEXT-INDENT: 0pt; DISPLAY: block"><br /></div><div style="TEXT-INDENT: 27pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">Our product revenue is generated predominantly from the sales of measurement and automation products.

These amounts are subsequently reclassified into earnings in the period during which the hedged transaction is realized. The gain or loss on the other derivatives as well as the offsetting gain or loss on the hedged item attributable to the hedged risk is recognized in current earnings under the line item &#8220;Net foreign exchange gain (loss)&#8221;.

The amendments establish a selling price hierarchy for determining the selling price of a deliverable. The selling price used for each deliverable will be based on vendor-specific objective evidence if available, third&#8211;party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. The amendments will change the application of the residual method of allocation and require that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. The relative selling price method allocates any discount in the arrangement proportionally to each deliverable on the basis of each deliverable&#8217;s selling price.
