NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 – Basis of presentation

The accompanying unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2009, included in our annual report on Form 10-K, filed with the Securities and Exchange Commission. In our opinion, the accompanying consolidated financial statements reflect all adjustments (consisting only of normal recurring items) considered necessary to present fairly our financial position at June 30, 2010 and December 31, 2009, and the results of our operations for the three month and six month periods ended June 30, 2010 and June 30, 2009 and the cash flows for the six month periods ended June 30, 2010 and June 30, 2009. Operating results for the three-month and six-month periods ended June 30, 2010, are not necessarily indicative of the results that may be expected for the year ending December 31, 2010.

Note 2 – Earnings per share

Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing net income by the weighted average number of common shares and common share equivalents outstanding (if dilutive) during each period. The number of common share equivalents, which include stock options and restricted stock units, is computed using the treasury stock method.

The reconciliation of the denominators used to calculate basic EPS and diluted EPS for the three month and six month periods ended June 30, 2010 and 2009, respectively, are as follows (in thousands):

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	(unaudited)				(unaudited)
	2010		2009		2010		2009
Weighted average shares outstanding-basic		77,932		77,556		77,657		77,417
Plus: Common share equivalents
Stock options, restricted stock units		1,060		268		1,095		179
Weighted average shares outstanding-diluted		78,992		77,824		78,752		77,596

Stock options to acquire 270,000 shares and 3,696,000 shares for the three month periods ended June 30, 2010 and 2009, respectively, and 285,000 and 4,973,000 shares for the six month periods ended June 30, 2010 and 2009, respectively, were excluded in the computations of diluted EPS because the effect of including the stock options would have been anti-dilutive.

Note 3 – Cash, cash equivalents and short-term investments

Note 4 – Fair value measurements

FASB ASC 820, Fair Value Measurements and Disclosures (FASB ASC 820) clarifies the definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value and expands disclosures about the use of fair value measurements. Effective January 1, 2010, we adopted the update to FASB ASC 820 that required additional disclosures and clarified existing disclosures regarding fair value measurements. The additional disclosures include transfers in and out of Level 1 and 2 as well as activity within Level 3 fair value measurements. The update also provides amendments that clarify existing disclosures on level of disaggregation and disclosures about inputs and valuation techniques. The adoption of the update to FASB ASC 820 did not have a material impact on our consolidated financial position or results of operations.

The following tables present our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value (in thousands). We did not have any items that were measured at fair value on a nonrecurring basis at June 30, 2010 and December 31, 2009.

Short-term investments available-for-sale are valued using a market approach (Level 1) based on the quoted market prices of identical instruments when available or other observable inputs such as trading prices of identical instruments in active markets. Short-term investments available-for-sale consists of debt securities issued by states of the U.S. and political subdivisions of the states, corporate debt securities and debt securities issued by U.S. government corporations and agencies. All short-term investments available-for-sale have contractual maturities of less than 24 months. There were not any transfers in or out of Level 1 during the six months ended June 30, 2010.

Derivatives include foreign currency forward and option contracts. Our foreign currency forward contracts are valued using an income approach (Level 2) based on the spot rate less the contract rate multiplied by the notional amount. Our foreign currency option contracts are valued using a market approach based on the quoted market prices which are derived from observable inputs including current and future spot rates, interest rate spreads as well as quoted market prices of identical instruments. There were not any transfers in or out of Level 2 during the six months ended June 30, 2010.

The short-term investment available-for-sale included in Level 3 is reported at its fair market value and consists of auction rate securities backed by education loan revenue bonds from the Vermont Student Assistance Corporation. The par value for this auction rate security was $2.2 million at June 30, 2010. The rating for this security at June 30, 2010, was Baa3/A/AA+. Auction rate securities are variable rate debt instruments whose interest rates are typically reset approximately every 7 to 35 days. On June 4, 2010, and in prior auction periods beginning in February 2008, the auction process for this security failed. At June 30, 2010, we reported this security as a short-term investment at its estimated fair market value of $2.1 million.

In November 2008, we accepted the UBS Auction Rate Securities Rights (the “Rights”) agreement offered by UBS as a liquidity alternative to the failed auction process. The Rights agreement is a nontransferable right to sell our auction rate securities, at par value, back to UBS at any time during the period June 30, 2010, through July 2, 2012. On June 14, 2010, under the terms of this Rights agreement, UBS purchased back from us our auction rate security from the New Hampshire Health and Education Facilities Authority. We received the full par value of $6.4 million from UBS in accordance with the terms or our Rights agreement. At June 30, 2010, we reported the portion of our Rights agreement related to our auction rate security from the Vermont Student Assistance Corporation at its estimated fair market value of $140,000 as a component of short-term debt securities available for sale.

The estimated fair market value of both the auction rate security and the Rights agreement was determined using significant unobservable inputs (Level 3). We considered many factors in determining the fair market value of our auction rate security as well as our corresponding Rights agreement at June 30, 2010, including the fact that the debt instruments underlying the auction rate security have redemption features which call for redemption at 100% of par value, current credit curves for like securities and discount factors to account for the illiquidity of the market for this security. During the six month period ended June 30, 2010, we did not make any significant changes to our valuation techniques or related inputs.

On July 1, 2010, under the terms of this Rights agreement, UBS purchased back from us our auction rate security from the Vermont Student Assistance Corporation. We received the full par value of $2.2 million from UBS in accordance with the terms of our Rights agreement.

Note 5 – Derivative instruments and hedging activities

FASB ASC 815, Derivatives and Hedging, (FASB ASC 815) requires companies to recognize all of their derivative instruments as either assets or liabilities in the statement of financial position at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation.

We have operations in over 40 countries. Sales outside of the Americas as a percentage of consolidated sales were 57% and 55% in each of the three month periods ended June 30, 2010 and 2009, respectively, and 58% and 56% in each of the six month periods ended June 30, 2010 and 2009, respectively. Our activities expose us to a variety of market risks, including the effects of changes in foreign-currency exchange rates. These financial risks are monitored and managed by us as an integral part of our overall risk management program.

We maintain a foreign currency risk management strategy that uses derivative instruments (foreign currency forward and purchased option contracts) to help protect our earnings and cash flows from fluctuations caused by the volatility in currency exchange rates. Movements in foreign currency exchange rates pose a risk to our operations and competitive position, since exchange rate changes may affect our profitability and cash flow, and the business or pricing strategies of our non-U.S. based competitors.

The vast majority of our foreign sales are denominated in the customers’ local currency. We purchase foreign currency forward and option contracts as hedges of forecasted sales that are denominated in foreign currencies and as hedges of foreign currency denominated receivables. These contracts are entered into to help protect against the risk that the eventual dollar-net-cash inflows resulting from such sales or firm commitments will be adversely affected by changes in exchange rates. We also purchase foreign currency forward contracts as hedges of forecasted expenses that are denominated in foreign currencies. These contracts are entered into to help protect against the risk that the eventual dollar-net-cash outflows resulting from foreign currency operating and cost of revenue expenses will be adversely affected by changes in exchange rates.

We designate foreign currency forward and purchased option contracts as cash flow hedges of forecasted revenues or forecasted expenses. In addition, we hedge our foreign currency denominated balance sheet exposures using foreign currency forward contracts. These derivatives are not designated as hedging instruments under FASB ASC 815. None of our derivative instruments contain a credit-risk-related contingent feature.

Cash flow hedges

To help protect against the reduction in value caused by a fluctuation in foreign currency exchange rates of forecasted foreign currency cash flows resulting from international sales or expenses over the next one to two years, we have instituted a foreign currency cash flow hedging program. We hedge portions of our forecasted revenue and forecasted expenses denominated in foreign currencies with forward and purchased option contracts. For forward contracts, when the dollar strengthens significantly against the foreign currencies, the change in the present value of future foreign currency cash flows may be offset by the change in the fair value of the forward contracts designated as hedges. For option contracts, when the dollar strengthens significantly against the foreign currencies, the change in the present value of future foreign c urrency cash flows may be offset by the change in the fair value of the option contracts net of the premium paid designated as hedges. Our foreign currency purchased option contracts are purchased “at-the-money” or “out-of-the-money”. We purchase foreign currency forward and option contracts for up to 100% of our forecasted exposures in selected currencies (primarily in Euro, Japanese yen, British pound sterling, South Korean won and Hungarian forint) and limit the duration of these contracts to 40 months or less.

For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of accumulated other comprehensive income (“OCI”) and reclassified into earnings in the same line item (net sales, operating expenses, or cost of sales) associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings or expenses during the current period and are classified as a component of “net foreign exchange gain (loss)”. Hedge effectiveness of foreign currency forwards and purchased option contracts d esignated as cash flow hedges are measured by comparing the hedging instrument’s cumulative change in fair value from inception to maturity to the forecasted transaction’s terminal value.

We held forward contracts with a notional amount of $14.9 million dollar equivalent of Euro, $2.1 million dollar equivalent of British pound sterling, $16.4 million dollar equivalent of Japanese yen, and $26.8 million dollar equivalent of Hungarian forint at June 30, 2010. These contracts are for terms of up to 24 months. At December 31, 2009, we held forward contracts with a notional amount of $28.6 million dollar equivalent of Euro, $4.0 million dollar equivalent of British pound sterling, $24.4 million dollar equivalent of Japanese yen, and $17.8 million dollar equivalent of Hungarian forint.

We held purchased option contracts with a notional amount of $14.8 million dollar equivalent of Euro at June 30, 2010. These contracts are for terms of up to 12 months. At December 31, 2009, we held purchased option contracts with a notional amount of $28.4 million dollar equivalent of Euro.

At June 30, 2010, we expect to reclassify $4.9 million of gains on derivative instruments from accumulated other comprehensive income to net sales during the next twelve months when the hedged international sales occur, $120,000 of losses on derivative instruments from accumulated OCI to cost of sales and $52,000 of losses on derivative instruments from accumulated OCI to operating expenses during the next twelve months when the hedged international expenses occur. Expected amounts are based on derivative valuations at June 30, 2010. Actual results may vary as a result of changes in the corresponding exchange rate subsequent to this date.

We did not record any gains or losses due to the ineffectiveness of our hedges during the six months ended June 30, 2010. During the six months ended June 30, 2009, hedges with a notional amount of $14.4 million were determined to be ineffective. As a result, we recorded a net gain of $512,000 related to these hedges as a component of “net foreign exchange gain (loss)” during the six months ended June 30, 2009.

Other Derivatives

Other derivatives not designated as hedging instruments under FASB ASC 815 consist primarily of foreign currency forward contracts that we use to hedge our foreign denominated net receivable or net payable positions to help protect against the change in value caused by a fluctuation in foreign currency exchange rates. We typically hedge up to 90% of our outstanding foreign denominated net receivables or net payables and typically limit the duration of these foreign currency forward contracts to approximately 90 days. The gain or loss on the derivatives as well as the offsetting gain or loss on the hedge item attributable to the hedged risk is recognized in current earnings under the line item “net foreign exchange gain (loss)”. As of June 30, 2010 and December 31, 2009, we held foreign currency forward contracts with a not ional amount of $35.9 million and $45.2 million, respectively.

Software development costs capitalized during the three month periods ended June 30, 2010 and 2009, were $8.0 million and $6.8 million, respectively, and related amortization expense was $2.5 million and $2.1 million, respectively. Capitalized software development costs for the three month periods ended June 30, 2010 and 2009, included costs related to stock based compensation of $349,000 and $391,000, respectively. During the six month periods ended June 30, 2010 and 2009, we capitalized software development costs of $11.5 million and $9.9 million, respectively, and related amortization expense was $5.1 million and $4.2 million, respectively. Capitalized software development costs for the six month periods ended June 30, 2010 and 2009, included costs related to stock based compensation of $511,000 and $546,000, respectively. Amortiza tion of capitalized software development costs is computed on an individual product basis for those products available for market and is recognized based on the product’s estimated economic life, generally three years. Patents are amortized using the straight-line method over their estimated period of benefit, generally ten to seventeen years. Total intangible assets amortization expenses were $4.1 million and $3.9 million during the three month periods ended June 30, 2010 and 2009, respectively, and $8.2 million and $7.5 million during the six month periods ended June 30, 2010 and 2009, respectively.

Acquired core technology and intangible assets are amortized over their useful lives, which range from three to eight years. Amortization expense for intangible assets acquired was approximately $1.0 million and $1.0 million for the three month periods ended June 30, 2010 and 2009, respectively, of which approximately $922,000 and $853,000 was recorded in cost of sales, respectively, and approximately $100,000 and $126,000 was recorded in operating expenses, respectively. For the six month periods ended June 30, 2010 and 2009, amortization expense for intangible assets acquired was approximately $1.9 million and $2.0 million, respectively, of which approximately $1.6 million and $1.7 million was recorded in cost of sales, respectively, and approximately $222,000 and $252,000 was recorded in operating expenses, respectively.

Note 8 – Goodwill

The carrying amount of goodwill as of June 30, 2010, is as follows (in thousands):

	Amount
Balance as of December 31, 2009	$	64,779
Acquisitions		5,013
Divestitures		-
Foreign currency translation impact		(1,223	)
Balance as of June 30, 2010	$	68,569

The excess purchase price over the fair value of assets acquired is recorded as goodwill. As we have one operating segment, we allocate goodwill to one reporting unit for goodwill impairment testing. Goodwill is tested for impairment on an annual basis, and between annual tests if indicators of potential impairment exist, using a fair-value-based approach based on the market capitalization of the reporting unit. Our annual impairment test was performed as of February 28, 2010. No impairment of goodwill has been identified during the period presented. Goodwill is deductible for tax purposes in certain jurisdictions.

On February 1, 2010, we acquired all of the outstanding shares of a privately-held company for $2.2 million in net cash, $3.0 million in shares of our common stock with the remainder to be paid in cash over the next four years. The purchase price allocation for this acquisition included net working capital of $1.1 million, amortizable intangible assets of $5.0 million, and goodwill of $5.0 million. Our consolidated financial statements include the operating results from the date of acquisition.

Note 9 – Income taxes

We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized.

FASB ASC 740, Income Taxes (FASB ASC 740) addresses the accounting for uncertainty in income taxes recognized in an entity’s financial statements and prescribes a recognition threshold and measurement attribute for financial statement disclosure of tax positions taken or expected to be taken on a tax return. We had $12.4 million and $11.1 million of unrecognized tax benefits at June 30, 2010 and December 31, 2009, respectively, all of which would affect our effective income tax rate if recognized. We recorded a gross decrease in unrecognized tax benefits of $1.1 million for the six month period ended June 30, 2010, as a result of a settlement with a taxing authority. As of June 30, 2010, it is deemed reasonable that we will recognize tax benefits in the amount of $2.4 mill ion in the next twelve months due to the closing of open tax years. The nature of the uncertainty is related to deductions taken on returns that have not been examined by the applicable tax authority. Our continuing policy is to recognize interest and penalties related to income tax matters in income tax expense. As of June 30, 2010, we have approximately $863,000 accrued for interest related to uncertain tax positions. The tax years 2003 through 2009 remain open to examination by the major taxing jurisdictions to which we are subject.

Our provision for income taxes reflected an effective tax rate of 16% and (7)% for the three month periods ended June 30, 2010 and 2009, respectively, and 12% and (179)% for the six month periods ended June 30, 2010 and 2009, respectively. For the three months ended June 30, 2010, our effective tax rate was lower than the U.S. federal statutory rate of 35% as a result of the partial release of a deferred tax asset valuation allowance, an enhanced deduction for certain research and development expenses and profits in foreign jurisdictions with reduced income tax rates. For the six months ended June 30, 2010, our effective tax rate was lower than the U.S. federal statutory rate of 35% as a result of the partial release of a deferred tax asset valuation allowance, an enhanced deduction for certain research and development expenses, profi ts in foreign jurisdictions with reduced income tax rates and a decrease in unrecognized tax benefits for uncertain tax positions. For the three and six month periods ended June 30, 2009, our effective tax rate was lower than the U.S. federal statutory rate of 35% due to a partial release of a deferred tax asset valuation allowance and the research credit. These benefits were partially offset by non-deductible stock-based compensation expenses, losses in foreign jurisdictions with reduced income tax rates and a valuation allowance related to a deferred tax asset for which a tax benefit was previously recognized.

The tax position of our Hungarian operation continues to benefit from assets created by the restructuring of our operations in Hungary. In addition, effective January 1, 2010, a new tax law in Hungary provides for an enhanced deduction for the qualified research and development expenses of NI Hungary Software and Hardware Manufacturing Kft. (“NI Hungary”). Partial release of the valuation allowance on assets from the restructuring and the enhanced tax deduction for research expenses resulted in income tax benefits of $4.6 million and $3.2 million for the three month periods ended June 30, 2010 and 2009, respectively and $7.8 million and $4.2 million for the six month periods ended June 30, 2010 and 2009, respectively.

Note 10 – Comprehensive income

Our comprehensive income is comprised of net income, foreign currency translation, unrealized gains and losses on forward and option contracts and unrealized gains and losses on our investments designated as available for sale. Comprehensive income for the three and six month periods ended June 30, 2010 and June 30, 2009, was as follows (in thousands):

Note 11 – Stock-based compensation plans

Stock option plans

Our stockholders approved the 1994 Incentive Stock Option Plan (the “1994 Plan”) on May 9, 1994. At the time of approval, 9,112,500 shares of our common stock were reserved for issuance under this plan. In 1997, an additional 7,087,500 shares of our common stock were reserved for issuance under this plan, and an additional 750,000 shares were reserved for issuance under this plan in 2004. The 1994 Plan terminated in May 2005, except with respect to outstanding awards previously granted thereunder.

Awards under the plan were either incentive stock options within the meaning of Section 422 of the Internal Revenue Code or nonqualified options. The right to purchase shares vests over a five to ten-year period, beginning on the date of grant. Vesting of ten year awards may accelerate based on the Company’s previous year’s earnings and revenue growth but shares cannot accelerate to vest over a period of less than five years. Stock options must be exercised within ten years from date of grant. Stock options were issued with an exercise price which was equal to the market price at the grant date. We estimate potential forfeitures of stock grants and adjust compensation cost recorded accordingly. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or ar e expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of stock compensation expense to be recognized in future periods. During the six months ended June 30, 2010, we did not make any changes in accounting principles or methods of estimates.

Restricted stock plans

Our stockholders approved our 2005 Incentive Plan (the “2005 Plan”) on May 10, 2005. At the time of approval, 2,700,000 shares of our common stock were reserved for issuance under this plan, as well as the number of shares which had been reserved but not issued under the 1994 Plan (our incentive stock option plan which terminated in May 2005), and any shares that returned to the 1994 Plan as a result of termination of options or repurchase of shares issued under such plan. The 2005 Plan, administered by the Compensation Committee of the Board of Directors, provided for granting of incentive awards in the form of restricted stock and restricted stock units (“RSUs”) to directors, executive officers and employees of the Company and its subsidiaries. Awards vest over a three, five or ten-year period, beginning on t he date of grant. Vesting of ten year awards may accelerate based on the Company’s previous year’s earnings and growth but ten year awards cannot accelerate to vest over a period of less than five years. The 2005 Plan terminated on May 11, 2010, except with respect to outstanding awards previously granted thereunder. There were 2,241,536 share of common stock that were reserved but not issued under the 1994 Plan and the 2005 Plan as of May 11, 2010.

Our stockholders approved our 2010 Incentive Plan (the “2010 Plan”) on May 11, 2010. At the time of approval, 2,000,000 shares of our common stock were reserved for issuance under this plan, as well as the 2,241,536 share of common stock that were reserved but not issued under the 1994 Plan and the 2005 Plan as of May 11, 2010, and any shares that are returned to the 1994 Plan and the 2005 Plan as a result of forfeiture or termination of options or RSUs or repurchase of shares issued under these plans. The 2010 Plan, administered by the Compensation Committee of the Board of Directors, provides for granting of incentive awards in the form of restricted stock and RSUs to employees, directors and consultants of the Company and employees and consultants of any parent or subsidiary of the Company. Awards vest over a three, fiv e or ten-year period, beginning on the date of grant. Vesting of ten year awards may accelerate based on the Company’s previous year’s earnings and growth but ten year awards cannot accelerate to vest over a period of less than five years. There were 4,219,216 shares available for grant under the 2010 Plan at June 30, 2010.

We estimate potential forfeitures of RSUs and adjust compensation cost recorded accordingly. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of stock compensation expense to be recognized in future periods. During the six months ended June 30, 2010, we did not make any changes in accounting principles or methods of estimates.

Employee stock purchase plan

Our employee stock purchase plan permits substantially all domestic employees and employees of designated subsidiaries to acquire our common stock at a purchase price of 85% of the lower of the market price at the beginning or the end of the purchase period. The plan has quarterly purchase periods beginning on February 1, May 1, August 1 and November 1 of each year. Employees may designate up to 15% of their compensation for the purchase of common stock under this plan. We had 1,398,050 shares of common stock reserved for future employee purchases under this plan at June 30, 2010. We issued 357,021 shares under this plan in the six months ended June 30, 2010. The weighted average fair value of the employees’ purchase rights was $23.82 per share and was estimated using the Black-Scholes model. During the six months ended June 30, 2010, we did not make any changes in accounting principles or methods of estimates.

For the three and six month periods ended June 30, 2010 and June 30, 2009, stock-based compensation recorded as a component of cost of sales, sales and marketing, research and development, and general and administrative was as follows (in thousands):

Authorized Preferred Stock and Preferred Stock Purchase Rights Plan

We have 5,000,000 authorized shares of preferred stock. On January 21, 2004, our Board of Directors designated 750,000 of these shares as Series A Participating Preferred Stock in conjunction with its adoption of a Preferred Stock Rights Agreement (the “Rights Agreement”) and declaration of a dividend of one preferred share purchase right (a “Right”) for each share of common stock outstanding held as of May 10, 2004 or issued thereafter. Each Right will entitle its holder to purchase one one-thousandth of a share of National Instruments’ Series A Participating Preferred Stock at an exercise price of $200, subject to adjustment, under certain circumstances. The Rights Agreement was not adopted in response to any effort to acquire control of National Instruments.

The Rights only become exercisable in certain limited circumstances following the tenth day after a person or group announces acquisitions of or tender offers for 20% or more of our common stock. In addition, if an acquirer (subject to certain exclusions for certain current stockholders of National Instruments, an “Acquiring Person”) obtains 20% or more of our common stock, then each Right (other than the Rights owned by an Acquiring Person or its affiliates) will entitle the holder to purchase, for the exercise price, shares of our common stock having a value equal to two times the exercise price. Under certain circumstances, our Board of Directors may redeem the Rights, in whole, but not in part, at a purchase price of $0.01 per Right. The Rights have no voting privileges and are attached to and automatically traded with our common stock until the occurrence of specified trigger events. The Rights will expire on the earlier of May 10, 2014 or the exchange or redemption of the Rights.

Note 12 – Segment information

We determine operating segments using the management approach. The management approach designates the internal organization that is used by management for making operating decisions and assessing performance as the source of our operating segments. It also requires disclosures about products and services, geographic areas and major customers.

We have defined our operating segment based on geographic regions. We sell our products in three geographic regions. Our sales to these regions share similar economic characteristics, similar product mix, similar customers, and similar distribution methods. Accordingly, we have elected to aggregate these three geographic regions into a single operating segment. Revenue from the sale of our products which are similar in nature and software maintenance are reflected as total net sales in our Consolidated Statements of Income.

Total net sales, operating income, interest income and long-lived assets, classified by the major geographic areas in which we operate, are as follows (in thousands):
