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, 2013, 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, 2014 and December 31, 2013,  and the results of our operations and comprehensive income for the three and six month periods endedJune 30, 2014, and the cash flows for the six months ended June 30, 2014. Operating results for the three and six month periods endedJune 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States.

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 (“RSUs”), is computed using the treasury stock method.  

The reconciliation of the denominators used to calculate basic EPS and diluted EPS for the three and six month periods ended June 30, 2014 and 2013, are as follows:

	Three Months Ended June 30,		Six Months Ended June 30,
	(In thousands)		(In thousands)
	(Unaudited)		(Unaudited)
	2014	2013	2014	2013
Weighted average shares outstanding-basic	126,887	124,377	126,433	123,845

Stock options, RSUs	625	893	690	979
Weighted average shares outstanding-diluted	127,512	125,270	127,123	124,824

Stock awards to acquire 13,500 shares and 538,100 shares for the three month periods ended June 30, 2014 and 2013, respectively, and 29,400 and 183,500 shares for the six month periods ended June 30, 2014 and 2013, respectively, were excluded in the computations of diluted EPS because the effect of including the stock awards would have been anti-dilutive.

Note 4 – Fair value measurements 

We define fair value to be the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market that market participants may use when pricing the asset or liability.   

We follow a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value measurement is determined based on the lowest level input that is significant to the fair value measurement. The three values of the fair value hierarchy are the following:   

Level 1 – Quoted prices in active markets for identical assets or liabilities   

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly   

Level 3 – Inputs that are not based on observable market data

We value our available-for-sale short-term investments based on pricing from third party pricing vendors, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. We classify all of our fixed income available-for-sale securities as having Level 2 inputs. The valuation techniques used to measure the fair value of our financial instruments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques. We believe all of these sources reflect the credit risk associated with each of our available-for-sale short-term investments. Short-term investments available-for-sale consists of debt securities issued by states of the U.S. and political subdivisions of the U.S., corporate debt securities and debt securities issued by U.S. government organizations and agencies as well as debt securities issued by foreign governments. All short-term investments available-for-sale have contractual maturities of less than 40 months.  

8

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 similar instruments. We consider counterparty credit risk in the valuation of our derivatives. However, counterparty credit risk did not impact the valuation of our derivatives during the six month period ended June 30, 2014. There were not any transfers in or out of Level 1 or Level 2 during thesix month period ended June 30, 2014.

Our foreign government bonds consist of German government sovereign debt denominated in Euro with maximum remaining maturities of 12 months. Our short-term investments do not involve sovereign debt from any other country in Europe.

We did not have any items that were measured at fair value on a nonrecurring basis at June 30, 2014 and December 31, 2013.  

The carrying value of net accounts receivable and accounts payable contained in the Consolidated Balance Sheets approximates fair value.

Note 5 – Derivative instruments and hedging activities  

We recognize all of our derivative instruments as either assets or liabilities in our 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, we 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 50 countries. Sales outside of the Americas accounted for approximately 62% of our revenues during each of the three month periods ended June 30, 2014 and 2013, and 61% and60% during each of the six month periods ended June 30, 2014 and 2013, 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 that are not designated as hedging instruments. 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 over the next one tothree 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 currency 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, Hungarian forint, British pound, and Malaysian ringgit) 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 loss.” Hedge effectiveness of foreign currency forwards and purchased option contracts designated 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 the following notional amounts:

(In thousands)		US Dollar Equivalent
		As of June 30, 2014		As of December 31,
		(Unaudited)		2013
Euro	$	110,755	$	75,886
Japanese yen		14,650		23,284
Hungarian forint		10,579		21,159
British pound		27,554		14,869
Malaysian ringgit		3,687		4,426
Total forward contracts notional amount	$	167,225	$	139,624

The contracts in the foregoing table had contractual maturities of 36 months or less at June 30, 2014 and December 31, 2013.  

At June 30, 2014, we expect to reclassify $182,000 of gains on derivative instruments from accumulated OCI to net sales during the next twelve months when the hedged international sales occur, $165,000 of gains on derivative instruments from accumulated OCI to cost of sales when the cost of sales are incurred and $165,000 of gains on derivative instruments from accumulated OCI to operating expenses during the next twelve months when the hedged operating expenses occur. Expected amounts are based on derivative valuations at June 30, 2014. Actual results may vary as a result of changes in the corresponding exchange rates subsequent to this date.  

We did not record any ineffectiveness from our hedges during the three and six month periods ended June 30, 2014 and 2013.  

Other Derivatives  

Other derivatives not designated as hedging instruments consist primarily of foreign currency forward contracts that we use to hedge our foreign denominated net receivable or net payable positions to protect against the change in value caused by a fluctuation in foreign currency exchange rates. We typically attempt to 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 120 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, 2014 and December 31, 2013, we held foreign currency forward contracts with a notional amount of $67 million and $70 million, respectively.

	$	208,750	$	(122,352)	$	86,398	$	192,980	$	(110,670)	$	82,310

Software development costs capitalized for the three month periods ended June 30, 2014 and 2013 were $9.6 million and $5.5 million, respectively, and related amortization expense was $3.0 million and $3.5 million, respectively. For the six month periods ended June 30, 2014 and 2013, capitalized software development costs were $17.6 million and $8.5 million, respectively, and related amortization expense was $6.1 million and $7.2 million, respectively. Capitalized software development costs for the three month periods ended June 30, 2014 and 2013 included costs related to stock based compensation of $146,000 and $262,000, respectively. For the six month periods ended June 30, 2014 and 2013, capitalized software development costs included costs related to stock based compensation of $340,000 and $402,000, respectively. The related amounts in the table above are net of fully amortized assets.

Amortization 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. Acquired technology and other intangible assets are amortized over their useful lives, which range from three to eight years. Patents are amortized using the straight-line method over their estimated period of benefit, generally 10 to 17 years. Total intangible assets amortization expenses were $7.3 million and $7.9 million for the three month periods ended June 30, 2014 and 2013, respectively, and $14.9 million and $16.3 million for the six month periods ended June 30, 2014 and 2013, respectively.

 Note 8 – Goodwill

The carrying amount of goodwill as of June 30, 2014, was as follows:

		Amount
		(In thousands)
Balance as of December 31, 2013	$	146,520
Purchase price adjustments		-
Foreign currency translation impact		(87)
Balance as of June 30, 2014 (unaudited)	$	146,433

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, 2014. No impairment of goodwill was identified during 2014 or 2013. Goodwill is deductible for tax purposes in certain jurisdictions.

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.  

We account for uncertainty in income taxes recognized in our financial statements using prescribed recognition thresholds and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on our tax returns. We had $24.7 million and $23.6 million of unrecognized tax benefits at June 30, 2014 and December 31, 2013, respectively, all of which would affect our effective income tax rate if recognized. We recorded a gross increase in unrecognized tax benefits of $471,000 and $976,000 for the three and six month periods ended June 30, 2014, respectively, as a result of tax positions taken during these periods. Our continuing policy is to recognize interest and penalties related to income tax matters in income tax expense. As of June 30, 2014, we had approximately $1.5 million accrued for interest related to uncertain tax positions. The tax years 2007 through 2013 remain open to examination by the major taxing jurisdictions to which we are subject.  The Internal Revenue Service (“IRS”) commenced an examination of our U.S. income tax returns for 2010 and 2011 in the second quarter of 2013 and such examination was not complete as of June 30, 2014.  However, in July 2014, we agreed to the IRS findings. Although such matter is still subject to final processing by the IRS, we believe the chance of further changes to the current IRS findings for 2010 and 2011 is remote and such matter is effectively settled. Accordingly, we anticipate recognizing tax benefits of $13.9 million in the three month period ended September 30, 2014 related to 2010 and 2011 intercompany transfer pricing activity.

Our provision for income taxes reflected an effective tax rate of 23% for each of the three month periods ended June 30, 2014 and 2013, and 23% and 10% for the six month periods ended June 30, 2014 and 2013, respectively. For the three and six month periods ended June 30, 2014, our effective tax rate was lower than the U.S. federal statutory rate of 35% as a result of an enhanced deduction for certain research and development expenses, profits in foreign jurisdictions with reduced income tax rates, and a tax benefit from disqualifying dispositions of equity awards that do not ordinarily result in a tax benefit. For the three and six month periods ended June 30, 2013, our effective tax rate was lower than the U.S. federal statutory rate of 35% as a result of an enhanced deduction for certain research and development expenses, profits in foreign jurisdictions with reduced income tax rates, the research and development tax credit, and a tax benefit from disqualifying dispositions of equity awards that do not ordinarily result in a tax benefit.

Our earnings in Hungary are subject to a statutory tax rate of 19%. The difference between this rate and the statutory U.S. rate of 35% resulted in income tax benefits of $2.4 million and $1.5 million for the three month periods ended June 30, 2014 and 2013, respectively, and $4.0 million and $3.2 million for the six month periods ended June 30, 2014 and 2013, respectively. No countries other than Hungary had a significant impact on our effective tax rate. We have not entered into any advanced pricing or other agreements with the IRS with regard to any foreign jurisdictions.  

The tax position of our Hungarian operation continues to benefit from assets created by the restructuring of our operations in Hungary. In addition, our research and development activities in Hungary continue to benefit from a tax law in Hungary that provides for an enhanced deduction for qualified research and development expenses. 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 $3.2 million and $2.3 million for the three month periods ended June 30, 2014 and 2013, respectively, and $5.8 million and $4.7 million for the six month periods ended June 30, 2014 and 2013, respectively.

Earnings from our operations in Malaysia are free of tax under a tax holiday effective January 1, 2013. This tax holiday expires in 2027. If we fail to satisfy the conditions of the tax holiday, this tax benefit may be terminated early. The tax holiday resulted in an income tax benefit of $6,000 and $311,000 for the three and six month periods ended June 30, 2014, respectively.

Note 11 – Authorized shares of common and preferred stock and stock-based compensation plans

Authorized shares of common and preferred stock

Following approval by the Company’s Board of Directors and stockholders, on May 14, 2013, the Company’s certificate of incorporation was amended to increase the authorized shares of common stock by 180,000,000 shares to a total of 360,000,000 shares. As a result of this amendment, the total number of shares which the Company is authorized to issue is 365,000,000 shares, consisting of (i) 5,000,000 shares of preferred stock, par value $.01 per share, and (ii) 360,000,000 shares of common stock, par value $.01 per share.

Stock option plans  

Our stockholders approved the 1994 Incentive Stock Option Plan (the “1994 Plan”) in May 1994. At the time of approval, 13,668,750 shares of our common stock were reserved for issuance under this plan. In 1997, an additional 10,631,250 shares of our common stock were reserved for issuance under this plan, and an additional 1,125,000 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.  

16

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 under the options 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 of our common stock 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 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 month period ended June 30, 2014, we did not make any changes in accounting principles or methods of estimates related to the 1994 Plan.  

Restricted stock plan  

Our stockholders approved our 2005 Incentive Plan (the “2005 Plan”) in May 2005. At the time of approval, 4,050,000 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 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 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. The 2005 Plan terminated on May 11, 2010, except with respect to outstanding awards previously granted thereunder. There were 3,362,304 shares 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, 3,000,000 shares of our common stock were reserved for issuance under this plan, as well as the 3,362,304 shares 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,  five 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 3,114,411 shares available for grant under the 2010 Plan at June 30, 2014.  

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 month period ended June 30, 2014, we did not make any changes in accounting principles or methods of estimates related to the 2010 Plan.  

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 generally 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. On May 12, 2014, our stockholders approved an additional 3,000,000 shares for issuance under our employee stock purchase plan. At June 30, 2014, we had 792,683 shares of common stock reserved for future issuance under this plan. We issued 588,059 shares under this plan in the six month period ended June 30, 2014. The weighted average purchase price of the employees’ purchase rights was $23.92 per share. During the six month period ended June 30, 2014, we did not make any changes in accounting principles or methods of estimates with respect to such plan.

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 the adoption of a Preferred Stock Rights Agreement which expired on May 10, 2014. There were not any shares of preferred stock issued and outstanding at June 30, 2014.

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 four 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 four 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:

Note 13 - Debt

On May 9, 2013, we entered into a Loan Agreement (the “Loan Agreement”) with Wells Fargo Bank, National Association. The Loan Agreement provides for a $50 million unsecured revolving line of credit with a scheduled maturity date of May 9, 2018 (the “Maturity Date”). Proceeds of loans made under the Loan Agreement may be used for working capital and other general corporate purposes. We may prepay the loans under the Loan Agreement in whole or in part at any time without premium or penalty. Certain of our existing and future material domestic subsidiaries are required to guaranty our obligations under the Loan Agreement. As of June 30, 2014, we had $50 million available for borrowings under this revolving line of credit.

The loans bear interest, at our option, at a base rate determined in accordance with the Loan Agreement, plus a spread of 0.0% to 0.5%, or a LIBOR rate plus a spread of 1.125% to 2.0%, in each case with such spread determined based on a ratio of consolidated indebtedness to EBITDA, determined in accordance with the Loan Agreement. Principal, together with all accrued and unpaid interest, is due and payable on the Maturity Date. We are also obligated to pay a quarterly commitment fee, payable in arrears, based on the available commitments at a rate of 0.175% to 0.300%, with such rate determined based on the ratio described above. The Loan Agreement contains customary affirmative and negative covenants. The affirmative covenants include, among other things, delivery of financial statements, compliance certificates and notices; payment of taxes and other obligations; maintenance of existence; maintenance of properties and insurance; and compliance with applicable laws and regulations. The negative covenants include, among other things, limitations on indebtedness, liens, mergers, consolidations, acquisitions and sales of assets, investments, changes in the nature of the business, affiliate transactions and certain restricted payments. The Loan Agreement also requires us to maintain a ratio of consolidated indebtedness to EBITDA equal to or less than 3.25 to 1.00, and a ratio of consolidated EBITDA to interest expense greater than or equal to 3.00 to 1.00, in each case determined in accordance with the Loan Agreement. As of June 30, 2014, we were in compliance with all covenants in the Loan Agreement.

The Loan Agreement contains customary events of default including, among other things, payment defaults, breaches of covenants or representations and warranties, cross-defaults with certain other indebtedness, bankruptcy and insolvency events, judgment defaults and change in our control, subject to grace periods in certain instances. Upon an event of default, the lender may declare all or a portion of the outstanding obligations payable by us to be immediately due and payable and exercise other rights and remedies provided for under the Loan Agreement. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default under the Loan Agreement at a per annum rate of interest equal to 2.00% above the otherwise applicable interest rate.

Note 14 – Commitments and Contingencies  

We offer a one-year limited warranty on most hardware products, with an optional two or three-year warranty on our hardware products, which is included in the sales price of our products. Provision is made for estimated future warranty costs at the time of the sale for the estimated costs that may be incurred under the basic limited warranty. Our estimate is based on historical experience and product sales during the period.  

The warranty reserve for the six month periods ended June 30, 2014 and 2013, respectively, was as follows:

Note 15 – Recently issued accounting pronouncements  

In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which amends ASC 740, Income Taxes. The amendments provide guidance on the financial statement presentation of an unrecognized tax benefit, as either a reduction of a deferred tax asset or as a liability, when a net operating loss carryforward, similar tax loss, or a tax credit carryforward exists. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 and may be applied on either a prospective or retrospective basis. The provisions are effective for the Company’s Form 10-K for the year ending December 31, 2014. We do not expect the adoption of these provisions to have a significant impact on our consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The update is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for annual reporting periods, and interim periods within that period, beginning after December 15, 2016 (fiscal year 2017 for the Company) and early adoption is not permitted. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. The Company has not yet determined the potential effects of the adoption of ASU 2014-09 on its Consolidated Financial Statements.

Note 16 – Litigation  

We are not currently a party to any material litigation. However, in the ordinary course of our business, we are involved in a limited number of legal actions, both as plaintiff and defendant, and could incur uninsured liability in any one or more of them. We also periodically receive notifications from various third parties related to alleged infringement of patents or intellectual property rights, commercial disputes or other matters. No assurances can be given with respect to the extent or outcome of any future litigation or dispute.

Note 17 – Subsequent events  

We have evaluated subsequent events through the date the financial statements were issued.  

On July 23, 2014, our Board of Directors declared a quarterly cash dividend of $0.15 per common share, payable on September 2, 2014, to stockholders of record on August 11, 2014.

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Any statements contained herein regarding our future financial performance or operations (including, without limitation, statements to the effect that we “believe,” "expect," "plan," "may," "will," "project," "continue," or "estimate" or other variations thereof or comparable terminology or the negative thereof) should be considered forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements as a result of a number of important factors, including those set forth under the heading “Risk Factors” beginning on page 36, and in the discussion below. Readers are also encouraged to refer to the documents regularly filed by us with the Securities and Exchange Commission, including our Annual Report on Form 10-K for the year ended December 31, 2013,  for further discussion of our business and the risks attendant thereto.

Overview

National Instruments Corporation (“we”, “us” or “our”) designs, manufactures and sells tools to engineers and scientists that accelerate productivity, innovation and discovery. Our graphical system design approach to engineering provides an integrated software and hardware platform that speeds the development of systems needing measurement and control. We believe our long-term vision and focus on technology supports the success of our customers, employees, suppliers and stockholders. We sell to a large number of customers in a wide variety of industries. We have been profitable in every year since 1990.

The key strategies that we focus on in running our business are the following:

Expanding our broad customer base

We strive to increase our already broad customer base and to grow our large order business by serving a large market on many computer platforms, through a global marketing and distribution network. We also seek to acquire new technologies and expertise from time to time to open new opportunities for our existing product portfolio.

Maintaining a high level of customer satisfaction

To maintain a high level of customer satisfaction we strive to offer innovative, modular and integrated products through a global sales and support network. We strive to maintain a high degree of backwards compatibility across different platforms to preserve the customer’s investment in our products. In this time of intense global competition, we believe it is crucial that we continue to offer products with quality and reliability, and that our products provide cost-effective solutions for our customers.

Leveraging external and internal technology

Our product strategy is to provide superior products by leveraging generally available technology, supporting openarchitectures on multiple platforms and by leveraging our core technologies such as custom application specific integrated circuits (“ASICs”)across multipleproducts.

We sell into test and measurement (“T&M”) and industrial/embedded applications in a broad range of industries and are subject to the economic and industry forces which drive those markets. It has been our experience that the performance of these industries and our performance are impacted by general trends in industrial production for the global economy and by the specific performance of certain vertical markets that are intensive consumers of measurement technologies. Examples of these markets are semiconductor capital equipment, telecom and mobile devices, consumer electronics, defense, aerospace and automotive.

Leveraging a worldwide sales, distribution and manufacturing network  

We distribute our software and hardware products primarily through a direct sales organization. We also use independent distributors, OEMs, VARs, system integrators and consultants to market our products. We have sales offices in the U.S. and sales offices and distributors in key international markets. Sales outside of the Americas accounted for approximately 62% of our revenues during each of the three month periods ended June 30, 2014 and 2013, and 61% and 60% for the six month periods ended June 30, 2014 and 2013, respectively. The vast majority of our foreign sales are denominated in the customers’ local currency, which exposes us to the effects of changes in foreign currency exchange rates. We expect that a significant portion of our total revenues will continue to be derived from international sales. (See Note 12 - Segment information of Notes to Consolidated Financial Statements for details concerning the geographic breakdown of our net sales, operating income, interest income and long-lived assets).  

21

We manufacture a substantial majority of our products at our facilities in Debrecen, Hungary and Penang, Malaysia. Additional production, primarily of RF products and of low volume, complex or newly introduced products is done in Austin, Texas, however, we will be transitioning substantially all of our Austin, Texas based manufacturing activities to our manufacturing facilities in Hungary and Malaysia over the next 12 to 18 months. In 2014, our site in Malaysia is expected to produce approximately 20% to 30% of our global production. This production is being generated by transferring existing products from our Hungarian production facility in support of anticipated growth in our business and introducing new products directly into our Malaysian facility. Our site in Hungary is expected to produce approximately 65% to 75% of our global production in 2014. Our product manufacturing operations can be divided into four areas: electronic circuit card and module assembly; chassis and cable assembly; technical manuals and product support documentation; and software duplication. Most of the electronic circuit card assemblies, modules and chassis are manufactured in house, although subcontractors are used from time to time. The majority of our electronic cable assemblies are produced by subcontractors; however, we do manufacture some on an exception basis. Our software duplication, technical manuals and product support documentation is primarily produced by subcontractors.  

Delivering high quality, reliable products

We believe that our long-term growth and success depend on delivering high quality software and hardware products on a timely basis. Accordingly, we focus significant efforts on research and development. We focus our research and development efforts on enhancing existing products and developing new products that incorporate appropriate features and functionality to be competitive with respect to technology, price and performance. Our success also is dependent on our ability to obtain and maintain patents and other proprietary rights related to technologies used in our products. We have engaged in litigation and where necessary, will likely engage in future litigation to protect our intellectual property rights. In monitoring and policing our intellectual property rights, we have been and may be required to spend significant resources.

Our operating results fluctuate from period to period due to changes in global economic conditions and a number of other factors. As a result, we believe our historical results of operations should not be relied upon as indications of future performance. There can be no assurance that our net sales will grow or that we will remain profitable in future periods.

Current business outlook  

Many of the industries we serve have historically been cyclical and have experienced periodic downturns. In assessing our business, we consider the trends in the Global Purchasing Managers’ Index (“PMI”), global industrial production as well as industry reports on the specific vertical industries that we target. In the three months ended June 30, 2014, the average of the PMI was 52.2 and the average of the new order element of the PMI was 53.3, both indicating economic expansion. We are unable to predict whether the industrial economy, as measured by the PMI, will remain above the neutral reading of 50, strengthen or contract during the remainder of 2014.

During the three month periods ended June 30, 2014 and 2013, we received $27 million and $13 million in new orders from our largest customer, respectively, and in the six month periods ended June 30, 2014 and 2013, we received $39 million and $30 million in new orders from this customer, respectively. During the three month periods ended June 30, 2014 and 2013, we recognized net revenue of $20 million and $23 million from these orders, respectively, and recognized net revenue of $27 million from these orders during each of the six month periods ended June 30, 2014 and 2013. The timing and amount of orders from this customer are unpredictable and therefore can cause unusual variations in the results and trends of our business. In the second quarter of 2014, we saw 4% year-over-year growth from orders under $20,000, 6% year-over-year growth from orders between $20,000 and $100,000, and 43% year-over-year growth from orders over $100,000. Excluding our largest customer, orders over $100,000 were up 22% year over year.

The improvement in the global PMI during the first half of 2014 and the reported second quarter improvement in personal computer sales give us confidence in the continued recovery of the industrial economy as we move through the remainder of 2014. However, we remain concerned with other economic and political events we saw during the first half of 2014. Of particular concern are the most recent sanctions against Russia by the European Union (EU) and the U.S. Such sanctions may limit access by Russian financial institutions to capital markets, impose embargoes on certain goods, or restrict sales of sensitive technologies, which alone or in combination may have a material adverse effect on our revenues and the financial results of our operations. In addition, we remain concerned about the geopolitical instability in the Middle East as well as the continued volatility of the currency markets in the emerging economies which could negatively impact the broader industrial economy. If the industrial economy as measured by the PMI begins to contract, it could have an adverse effect on the spending patterns of businesses including our current and potential customers which could adversely affect our revenues and results of operations.

Results of Operations for the three and six month periods ended June 30, 2014 and 2013  

Net Sales.  Our net sales were $313 million and $296 million for the three month periods ended June 30, 2014 and 2013, respectively, an increase of 6%. For the same periods, product sales were $288 million and $276 million, an increase of 5%, and software maintenance sales were $24 million and $20 million, an increase of 20%. Software maintenance sales grew at a faster rate than overall net sales as a result of a greater mix of software sales during the three month period ended June 30, 2014, compared to the three month period ended June 30, 2013.

For the six month periods ended June 30, 2014 and 2013, our consolidated net sales were $597 million and $583 million, respectively, an increase of 3%. For the same periods, product sales were $550 million and $541 million, respectively, an increase of 2%, and software maintenance sales were $47 million and $42 million, respectively, an increase of 13%. Software maintenance sales grew at a faster rate than overall net sales as a result of a greater mix of software sales during the six month period ended June 30, 2014, compared to the six month period ended June 30, 2013.

We do not typically maintain a large amount of order backlog as orders typically translate to sales quickly. As such, any change in the pattern of our orders will typically have an impact on our net sales in the short term.

During the three month period ended June 30, 2014, we implemented a moderate price increase which had less than a 2% impact on our net sales. We did not take any significant action with regard to pricing during the three or six month periods ended June 30, 2013.

23

Large orders, defined as orders with a value greater than $100,000, increased by 43% year over year during the three months ended June 30, 2014, compared to the year over year decrease of 30% in the three month period ended June 30, 2013. In the six month period ended June 30, 2014, large orders increased by 15% year over year compared to year over year decrease of 5% during the six month period ended June 30, 2013. A significant amount of our large order growth in the three month and six month periods ended June 30, 2014, compared to the comparable periods in 2013 was the result of orders from our largest customer. Year over year, orders from this customer increased by 117% in the three month period ended June 30, 2014, and increased by 31% in the six month period ended June 30, 2014. Excluding the impact of our largest customer, large orders increased by 22% year over year during the three month period ended June 30, 2014, and increased by 10% year over year during the six month period ended June 30, 2014, compared to the six month period ended June 30, 2013. Orders from our largest customer are discussed in more detail below. During the three month periods ended June 30, 2014 and 2013, large orders were 26% and 21% of our total orders, respectively, and for the six month periods ended June 30, 2014 and 2013, large orders were 23% and 22% of our total orders, respectively. Larger orders are more volatile, are subject to greater discount variability and may contract at a faster pace during an economic downturn.

With respect to our largest customer, we are serving four different applications for this customer, each involving the use of LabVIEW and the NI PXI platform. During the three month period ended June 30, 2014 and 2013, we received $27 million and $13 million, respectively, in new orders from our largest customer. During the six month periods ended June 30, 2014 and 2013, we received $39 million and $30 million, respectively, in new orders from this same customer. In the three month periods ended June 30, 2014 and 2013, we recognized net revenue of $20 million and $23 million, respectively, from these orders, and in each of the six month periods ended June 30, 2014 and 2013, we recognized net revenue from these orders of $27 million.

For the three month periods ended June 30, 2014, and 2013, net sales in the Americas were $120 million and $113 million, respectively, an increase of 7%. Sales in the Americas, as a percentage of consolidated sales were 38% in each of the three month periods ended June 30, 2014, and 2013. In Europe, net sales were $84 million and $75 million in the three month periods ended June 30, 2014, and 2013, respectively, an increase of 12%. Sales in Europe, as a percentage of consolidated sales were 27% and 25% in the three month periods ended June 30, 2014 and 2013, respectively. In East Asia, net sales were $81 million and $82 million in the three month periods ended June 30, 2014 and 2013, respectively, a decrease of 1%. Sales in East Asia, as a percentage of consolidated sales were 26% and 28% in the three month periods ended June 30, 2014 and 2013, respectively. In Emerging Markets, net sales were $28 million and $27 million in the three month periods ended June 30, 2014 and 2013, respectively, a increase of 4%. Sales in Emerging Markets, as a percentage of consolidated sales were 9% in each of the three month periods ended June 30, 2014 and 2013.

For the six month periods ended June 30, 2014 and 2013, net sales in the Americas were $235 million and $232 million, respectively, an increase of 1%. Sales in the Americas, as a percentage of consolidated sales were 39% and 40% in the six month periods ended June 30, 2014 and 2013, respectively. In Europe, net sales were $167 million and $154 million in the six month periods ended June 30, 2014 and 2013, respectively, an increase of 9%. Sales in Europe, as a percentage of consolidated sales were 28% and 26% in the six month periods ended June 30, 2014 and 2013, respectively. In East Asia, net sales were $142 million in each of the six month periods ended June 30, 2014 and 2013. Sales in East Asia, as a percentage of consolidated sales were 24% in each of the six month periods ended June 30, 2014 and 2013. In Emerging Markets, net sales were $53 million and $54 million in the six month periods ended June 30, 2014 and 2013, respectively, a decrease of 3%. Sales in Emerging Markets, as a percentage of consolidated sales were 9% in each of the six month periods ended June 30, 2014 and 2013.

We expect sales outside of the Americas to continue to represent a significant portion of our revenue. We intend to continue to expand our international operations by increasing our presence in existing markets, adding a presence in some new geographical markets and continuing the use of distributors to sell our products in some countries.  

Almost all of the sales made by our direct sales offices in the Americas (excluding the U.S.), Europe, East Asia, and Emerging Markets are denominated in local currencies, and accordingly, the U.S. dollar equivalent of these sales is affected by changes in foreign currency exchange rates. For the three month period ended June 30, 2014, in local currency terms, our consolidated net sales increased by $15 million or 5%, Americas sales increased by $8 million or 7%, European sales increased by $5 million or 7%, East Asia sales decreased by $1 million or 1%, and Emerging Markets sales increased by $3 million or 11%, compared to the three month period ended June 30, 2013. During this same period, the change in exchange rates had the effect of increasing our consolidated sales by $1.5 million or 0.5%, decreasing Americas sales by $659,000 or 0.6%, increasing European sales by $4.7 million or 6%, decreasing East Asia sales by $439,000 or 0.5%, and decreasing sales in Emerging Markets by $2.1 million or 8%.  

For the six month period ended June 30, 2014, in local currency terms, our consolidated net sales increased by $18 million or 3%, Americas sales increased by $5 million or 2%, European sales increased by $9 million or 6%, East Asia sales increased by $1 million or 1%, and Emerging Markets sales increased by $3 million or 5%, compared to the six month period ended June 30, 2013. During this same period, the change in exchange rates had the effect of decreasing our consolidated sales by $2.9 million or 0.5%, decreasing Americas sales by $2.2 million or 1%, increasing European sales by $6.8 million or 4%, decreasing East Asia sales by $3 million or 2%, and decreasing sales in Emerging Markets by $4.6 million or 8%.

To help protect against changes in U.S. dollar equivalent value caused by fluctuations in foreign currency exchange rates of forecasted foreign currency cash flows resulting from international sales, we have instituted a foreign currency cash flow hedging program. We hedge portions of our forecasted revenue denominated in foreign currencies with average rate forward contracts. During the three month period ended June 30, 2014, these hedges had the effect of decreasing our consolidated sales by $231,000 and during the three month period ended June 30, 2013, these hedges had the effect of increasing our consolidated sales by $804,000. During the six month periods ended June 30, 2014 and June 30, 2013, these hedges had the effect of increasing our consolidated sales by $115,000 and $2.0 million, respectively. (See Note 5 - Derivative instruments and hedging activities of Notes to Consolidated Financial Statements for further discussion regarding our cash flow hedging program and its related impacted on our consolidated sales for 2014 and 2013).

Gross Profit. For the three month periods ended June 30, 2014 and 2013, gross profit was $231 million and $212 million, respectively, an increase of 9%. As a percentage of sales, gross profit was 74% and 72% for the three month periods ended June 30, 2014 and 2013, respectively. For the six month periods ended June 30, 2014 and 2013, gross profit was $444 million and $429 million, respectively, an increase of 4%. As a percentage of sales, gross profit was 74% for each of the six month periods ended June 30, 2014 and 2013. During the three month period ended June 30, 2014, our gross margin was impacted favorably by higher production volumes in response to higher sales volumes, improved sales mix of products, such as software, with higher margins and a moderate price increase which had an overall impact of less than 2% on our net sales. We continue to focus on cost control and cost reduction measures throughout our manufacturing cycle.

For the three month periods ended June 30, 2014 and 2013, the change in exchange rates had the effect of increasing our cost of sales by $1.5 million and decreasing our cost of sales by $206,000, respectively. For the six month periods ended June 30, 2014 and 2013, the change in exchange rates had the effect of decreasing our cost of sales by $648,000 and $200,000, respectively. To help protect against changes in our cost of sales caused by a fluctuation in foreign currency exchange rates of forecasted foreign currency cash flows, we have a foreign currency cash flow hedging program. We hedge portions of our forecasted costs of sales denominated in foreign currencies with average rate forward contracts. During the three month periods ended June 30, 2014 and 2013, these hedges had the effect of decreasing our cost of sales by $101,000 and increasing our cost of sales by $34,000, respectively. During the six month periods ended June 30, 2014 and 2013, these hedges had the effect of decreasing our cost of sales by $182,000 and $74,000, respectively. (See Note 5 - Derivative instruments and hedging activities of Notes to Consolidated Financial Statements for further discussion regarding our cash flow hedging program and its related impacted on our consolidated sales for 2014 and 2013).  

Operating Expenses. For the three month periods ended June 30, 2014 and 2013, operating expenses were $199 million and $193 million, respectively, an increase of 3%. As a percent of sales, operating expenses were 64% and 65% for the three month periods ended June 30, 2014 and 2013, respectively. For the three month period ended June 30, 2014, the increase in our operating expenses was due to an increase in personnel related expenses of $10 million offset by a $4 million decrease in software development costs. The increase in personnel related expenses was driven by an increase in commissions due to higher sales volume, an increase in variable compensation due to the overall improvement in our operating results compared to the three month period ended June 30, 2013, as well as raises for eligible employees. The decrease in our software development costs coincides with the increase in our capitalized software compared to the three month period ended June 30, 2013. Over the same period, the net impact of changes in foreign currency exchange rates increased our operating expense by $127,000.

For the six month periods ended June 30, 2014 and 2013, operating expenses were $389 million and $390 million, respectively. As a percent of sales, operating expenses were 65% and 67% for the six month periods ended June 30, 2014 and 2013, respectively. For the six month period ended June 30, 2014, we saw an increase in personnel related expenses of $11 million offset by a $9 million decrease in software development costs. The increase in personnel related expenses was driven by an increase in commissions due to higher sales volumes as well as an increase variable compensation due to the overall improvement in our operating results compared to the six month period ended June 30, 2013. The decrease in our software development costs coincides with the $9 million increase in our capitalized software compared to the six month period ended June 30, 2013. The increase in our capitalized software is consistent with our focus on new product development to support future growth in our business. Over the same period, the net impact of changes in foreign currency exchange rates decreased our operating expenses by $1.6 million.

We believe that our long-term growth and success depends on developing high quality software and hardware products on a timely basis. We are focused on leveraging recent investments in research and development and in our field sales force and taking actions to help ensure those resources are focused in areas and initiatives that will contribute to future growth in our business. For the three month periods ended June 30, 2014 and 2013, our sales and marketing expenses were $119 million and $113 million, respectively, and research and development expenses were $56 million and $58 million, respectively. For the six month periods ended June 30, 2014 and 2013, our sales and marketing expenses were $231 million and $227 million, respectively, and research and development expenses were $111 million and $120 million, respectively. Sales and marketing headcount increased by 75 from June 30, 2013 to June 30, 2014. Research and development headcount decreased by 24 from June 30, 2013 to June 30, 2014.

25

From a regional perspective, the decrease in research and development expenses had a larger impact on the operating expenses of the Americas as the Americas absorbed $3.2 million of the overall $2.6 million decrease while the other regions offset this by a $619,000 increase in research and development expenses in the three month period ended June 30, 2014. In the six month period ended June 30, 2014, the $9 million decrease was primarily in the Americas.

Operating Income.  For the three month period ended June 30, 2014 and 2013, operating income was $32 million and $19 million, respectively, an increase of 67%. As a percentage of net sales, operating income was 10% and 6%, respectively, in these same periods. For the six month periods ended June 30, 2014 and 2013, operating income was $56 million and $39 million, respectively, an increase of 45%. As a percentage of net sales, operating income was 9% and 7%, respectively, in these same periods. The increases in operating income in absolute dollars and as a percentage of sales for the three and six month periods ended June 30, 2014, compared to the three and six month periods ended June 30, 2013, are attributable to the factors discussed in Net Sales, Gross Profit and Operating Expenses above.

Interest Income.For the three month periods ended June 30, 2014 and 2013, interest income was $234,000 and $177,000, respectively. For the six month periods ended June 30, 2014 and 2013, interest income was $431,000 and $362,000, respectively. We continue to see low yields for high quality investment alternatives that comply with our corporate investment policy. We do not expect yields in these types of investments to increase significantly during the remainder of 2014. 

Net Foreign Exchange Loss.For the three month periods ended June 30, 2014 and 2013, net foreign exchange loss was $(603,000) and $(1.1) million, respectively. During the six month periods ended June 30, 2014 and 2013, net foreign exchange loss was $(553,000) and $(2.5) million, respectively. These results are attributable to movements in the foreign currency exchange rates between the U.S. dollar and foreign currencies in subsidiaries for which our functional currency is not the U.S. dollar. During the three and six month periods ended June 30, 2014, there was mixed volatility in the exchange rates between the U.S. dollar and most of the major currencies in the markets in which we do business with strengthening of the U.S. dollar against currencies in emerging markets, particularly the Russian ruble, the Chinese yuan and the Hungarian forint along with a weakening of the U.S. dollar against the Euro and British pound. We cannot predict the direction or degree of future volatility in these exchange rates. In the past, we have noted that significant volatility in foreign currency exchange rates in the markets in which we do business has had a significant impact on the revaluation of our foreign currency denominated firm commitments, on our ability to forecast our U.S. dollar equivalent revenues and expenses and on the effectiveness of our hedging programs. In the past, these dynamics have also adversely affected our revenue growth in international markets and may pose similar challenges in the future. We recognize the local currency as the functional currency in virtually all of our international subsidiaries.   

We utilize foreign currency forward contracts to hedge our foreign denominated net foreign currency balance sheet 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 receivable or payable positions and typically limit the duration of these foreign currency forward contracts to approximately 90 days. The gain or loss on these 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 “Net foreign exchange gain (loss)”. Our hedging strategy decreased our foreign exchange gains by $742,000 in the three month period ended June 30, 2014 and decreased our foreign exchange losses by $502,000 in the three month period ended June 30, 2013. Our hedging strategy decreased our foreign exchange gains by $810,000 in the six month period ended June 30, 2014, and decreased our foreign exchange losses by $1.8 million in the six month period ended June 30, 2013.

Provision for Income Taxes.For each of the three month periods ended June 30, 2014 and 2013, our provision for income taxes reflected an effective tax rate of 23%. For the six month periods ended June 30, 2014 and 2013, our provision for income taxes reflected an effective tax rate of 23% and 10%, respectively.  The factors that caused our effective tax rate to change year-over-year are detailed in the table below:

	Three Months Ended		Six Months Ended
	June 30, 2014		June 30, 2014
	(Unaudited)		(Unaudited)
Effective tax rate at June 30, 2013	23	%	10	%

Change in intercompany profit	(2)		(2)
Change in tax benefit from equity awards	-		1
Change in research and development tax credit	3		12
Other	(1)		-
Effective tax rate at June 30, 2014	23	%	23	%

The Internal Revenue Service (“IRS”) commenced an examination of our U.S. income tax returns for 2010 and 2011 in the second quarter of 2013 and such examination was not complete as of June 30, 2014.  However, in July 2014, we agreed to the IRS findings. Although such matter is still subject to final processing by the IRS, we believe the chance of further changes to the current IRS findings for 2010 and 2011 is remote and such matter is effectively settled. Accordingly, we anticipate recognizing tax benefits of $13.9 million in the three month period ended September 30, 2014 related to 2010 and 2011 intercompany transfer pricing activity.

(See Note 9 – Income taxes of Notes to Consolidated Financial Statements for further discussion regarding changes in our effective tax rate and a reconciliation of income taxes at the U.S. federal statutory income tax rate of 35% to our effective tax rate).

Liquidity and Capital Resources  

Working Capital, Cash and Cash Equivalents and Short-term Investments.  Cash, cash equivalents and short-term investments increased by $8 million to $402 million atJune 30, 2014 from $393 million at December 31, 2013. The following table presents our working capital, cash and cash equivalents and short-term investments:    

		June 30, 2014		December 31,
(In thousands)		(unaudited)		2013		Increase
Working capital	$	634,687	$	603,240	$	31,447
Cash and cash equivalents (1)		237,496		230,263		7,233
Short-term investments (1)		164,017		163,149		868
Total cash, cash equivalents and short-term investments	$	401,513	$	393,412	$	8,101
(1) Included in working capital

During the six month period ended June 30, 2014, our working capital increased by $31 million. Overall, current assets increased by $57 million while current liabilities increased by $25 million. The increase in our current assets was the result of an $8 million increase in cash, cash equivalents and short-term investments, an increase in accounts receivable of $30 million and an increase in prepaid expense and other current assets of $27 million. These increases were offset by a decrease in inventory of $4.8 million and a decrease in deferred income taxes of $3.6 million. The increase in current liabilities was the result of an increase in accounts payable of $7.4 million, an increase in accrued compensation of $7.5 million and an increase in deferred revenue of $8.5 million. The overall increases in working capital can be attributed to our overall profitability during the six month period ended June 30, 2014. 

Accounts receivable increased by $30 million to $211 million at June 30, 2014, from $181 million at December 31, 2013. Days sales outstanding increased to 59 days at June 30, 2014, compared to 57 days at December 31, 2013. The increase in accounts receivable is the result of a high volume of our sales occurring in the last month of the three month period ended June 30, 2014.

Inventory decreased by $4.8 million to $167 million at June 30, 2014, from $172 million at December 31, 2013. Inventory turns remained unchanged at 1.8 at June 30, 2014 and December 31, 2013. The decrease in inventory was driven by the increase in sales during the three month period ended June 30, 2014.

Prepaid expenses and other current assets increased $27 million to $76 million at June 30, 2014, from $49 million at December 31, 2013. The increase in prepaid expenses and other current assets is a result of the timing of payments of U.S. federal taxes as well as value added taxes (VAT) in various jurisdictions and insurance and maintenance contracts.

Our cash and cash equivalent balances are held in numerous financial institutions throughout the world, including substantial amounts held outside of the U.S., however, the majority of our cash and investments that are located outside of the U.S. are denominated in the U.S. dollar with the exception of $8 million U.S. dollar equivalent of German government sovereign debt and $25 million U.S. dollar equivalent of corporate bonds that are denominated in Euro. Our German government sovereign debt holdings have a maximum remaining maturity of 12 months and carry Aaa/AAA ratings. Our short-term investments do not include sovereign debt from any other countries in Europe. At June 30, 2014, we had $402 million in cash, cash equivalents and short-term investments. Approximately $62 million or 15% of these amounts were held in domestic accounts with various financial institutions and $340 million or 85% was held in accounts outside of the U.S. with various financial institutions. At June 30, 2014, we had cash and cash equivalents of $237 million of which $62 million or 26% was held in domestic accounts and $176 million or 74% was held in various accounts of our foreign subsidiaries. At June 30, 2014, we had short-term investments of $164 million, all of which was held in investment accounts of our foreign subsidiaries. Most of the amounts held outside of the U.S. could be repatriated to the U.S., but under current law, would be subject to U.S. federal income taxes, less applicable foreign tax credits. We have provided for the U.S. federal tax liability on these amounts for financial statement purposes, except for foreign earnings that are considered indefinitely reinvested outside of the U.S. Repatriation could result in additional U.S. federal income tax payments in future years. We utilize a variety of tax planning and financing strategies with the objective of having our worldwide cash available in the locations in which it is needed.

Cash Provided by and (Used in) in the six month period ended June 30, 2014. The following table summarizes the proceeds and (uses) of cash:  

		Six Months Ended June 30,
(In thousands)		(unaudited)
		2014		2013
Cash provided by operating activities	$	68,438	$	44,392
Cash used in investing activities		(41,408)		(24,735)
Cash used in financing activities		(19,797)		(12,073)
Net change in cash equivalents		7,233		7,584
Cash and cash equivalents at beginning of year		230,263		161,996
Cash and cash equivalents at end of period	$	237,496	$	169,580

For the six month periods ended June 30, 2014 and 2013, cash provided by operating activities was $68 million and $44 million, respectively, an increase of $24 million. This increase was due to an increase in net income of $10 million and an increase in cash provided by our operating assets of $14 million.

Investing activities used cash of $41 million during the six month period ended June 30, 2014, as the result of capital expenditures of $22 million and capitalization of internally developed software and other intangibles of $18 million. During the six month period ended June 30, 2013, we were still making payments related to the finishing stages of the construction of our Malaysian manufacturing facility. During the six month period ended June 30, 2014, we were no longer making significant payments for our Malaysian manufacturing facility and as a result, capital expenditures during the six month period ended June 30, 2014, declined by $11 million. Capital expenditures during the six month period ended June 30, 2014, included leasehold improvements, expansion of existing facilities, computers, equipment and furniture and fixtures to support operations throughout our business. Investing activities used cash of $25 million during the six month period ended June 30, 2013, as the result of capital expenditures of $33 million and capitalization of internally developed software and other intangibles of $11 million, offset by the net sale of $19 million of short-term investments to fund liquidity for operating needs. Capital expenditures during the six month period ended June 30, 2013, included payments related to additional land use rights and the finishing stages of the construction of our Malaysian manufacturing facility as well as leasehold improvements, computers, equipment and furniture and fixtures to support operations in our Malaysian manufacturing facility as well as other parts of our business.  

Financing activities used cash of $20 million during the six month period ended June 30, 2014, which was the net result of $38 million used to pay our dividends offset by $17 million received from the issuance of our common stock from the exercise of employee stock options and from our employee stock purchase plan. Financing activities used cash of $12 million during the six month period ended June 30, 2013, which was the result of $35 million used to pay our dividends offset by $21 million received from the issuance of our common stock from the exercise of employee stock options and from our employee stock purchase plan.

From time to time, our Board of Directors has authorized various programs to repurchase shares of our common stock depending on market conditions and other factors. We did not make any purchases under this program during the six month period ended June 30, 2014. At June 30, 2014, there were 3,932,245 shares remaining available for repurchase under this program. This repurchase program does not have an expiration date.  

During the six month period ended June 30, 2014, we received less proceeds from the exercise of stock options compared to the six month period ended June 30, 2013. The timing and number of stock option exercises and the amount of cash proceeds we receive through those exercises are not within our control and in the future, we may not generate as much cash from the exercise of stock options as we have in the past. Moreover, since 2005, it has been our practice to issue RSUs and not stock options to eligible employees which has reduced the number of stock options available for exercise in the future. Unlike the exercise of stock options, the issuance of shares upon vesting of RSUs does not result in any cash proceeds to us.  As of June 30, 2014, there were outstanding options to purchase 84,461 shares of our common stock of which options for 23,373 shares have expiration dates in 2014. These options have weighted average exercise prices of between $14.63 per share and $19.51 per share. As such, we will not generate as much cash from the exercise of stock options during the remainder of 2014 and very little if any after 2014.

Contractual Cash Obligations.  Purchase obligations primarily represent purchase commitments for customized inventory and inventory components. At June 30, 2014, we had non-cancelable purchase commitments with various suppliers of customized inventory and inventory components totaling approximately $9 million. At December 31, 2013, we had non-cancelable purchase commitments with various suppliers of customized inventory and inventory components totaling approximately $11 million.  

Guarantees are related to payments of customs and foreign grants. At June 30, 2014, we had outstanding guarantees for payment of customs and foreign grants totaling approximately $13 million. At December 31, 2013, we had outstanding guarantees for payment of customs, foreign grants and potential customer disputes totaling approximately $5.2 million.

29

Loan Agreement. On May 9, 2013, we entered into a Loan Agreement (the  “Loan Agreement”) with Wells Fargo Bank, National Association. The Loan Agreement provides for a $50 million unsecured revolving line of credit with a scheduled maturity date of May 9, 2018 (the “Maturity Date”). Proceeds of loans made under the Loan Agreement may be used for working capital and other general corporate purposes. We may prepay the loans under the Loan Agreement in whole or in part at any time without premium or penalty. Certain of our existing and future material domestic subsidiaries are required to guaranty our obligations under the Loan Agreement. We may choose to borrow funds against this line of credit in future periods to have sufficient domestic cash to fund continued dividends to our stockholders, to fund potential acquisitions or other domestic general corporate purposes without the need to repatriate foreign earnings. At June 30, 2014, we did not have any amounts outstanding or due as a result of borrowings under this line of credit.

Off-Balance Sheet Arrangements.We do not have any off-balance sheet debt. At June 30, 2014, we did not have any relationships with any unconsolidated entities or financial partnerships, such as entities often referred to as structured finance entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. As such, we are not exposed to any financing, liquidity, market or credit risk that could arise if we were engaged in such relationships.  

Prospective Capital Needs.We believe that our existing cash, cash equivalents and short-term investments, together with cash generated from operations as well as from the purchase of common stock through our employee stock purchase plan and available borrowings under our Loan Agreement will be sufficient to cover our working capital needs, capital expenditures, investment requirements, commitments, payment of dividends to our stockholders and repurchases of our common stock for at least the next 12 months, although the use of certain of our funds for domestic purposes may require us to repatriate foreign earnings which would be subject to the U.S. federal statutory tax rate of 35%. We may also seek to pursue additional financing or to raise additional funds by selling equity or debt to the public or in private transactions. If we elect to raise additional funds, we may not be able to obtain such funds on a timely basis on acceptable terms, if at all. If we raise additional funds by issuing additional equity or convertible debt securities, the ownership percentages of our existing stockholders would be reduced. In addition, the equity or debt securities that we issue may have rights, preferences or privileges senior to those of our common stock. We may also choose to repatriate foreign earnings which would be subject to the U.S. federal statutory tax rate of 35% and therefore, would likely have a material adverse effect on our effective tax rate and on our net income and earnings per share. We could also choose to reduce certain expenditures or payments of dividends or suspend our program to repurchase shares of our common stock. Historically, we have not had to rely on debt, public or private, to fund our operating, financing or investing activities.

Although we believe that we have sufficient capital to fund our operating activities for at least the next 12 months, our future capital requirements may vary materially from those now planned. We anticipate that the amount of capital we will need in the future will depend on many factors, including:

· payment of dividends to our stockholders;

· difficulties and the high tax costs associated with the repatriation of earnings;

· required levels of research and development and other operating costs;

· our business, product, capital expenditure and research and development plans, and product and technology roadmaps; 

· the overall levels of sales of our products and gross profit margins;

· the levels of inventory and accounts receivable that we maintain;

· general economic and political uncertainty and specific conditions in the markets we address, including any volatility in the industrial economy in the various geographic regions in which we do business;

· the inability of certain of our customers who depend on credit to have access to their traditional sources of credit to finance the purchase of products from us, which may lead them to reduce their level of purchases or to seek credit or other accommodations from us;

· acquisitions of other businesses, assets, products or technologies;

· capital improvements for new and existing facilities; 

· repurchases of our common stock; 

· our relationships with suppliers and customers; and 

· the level of purchases under our employee stock purchase plan.

Item 3.Quantitative and Qualitative Disclosures About Market Risk

Financial Risk Management  

Our international sales are subject to inherent risks, including fluctuations in local economies; fluctuations in foreign currencies relative to the U.S. dollar; difficulties in staffing and managing foreign operations; greater difficulty in accounts receivable collection; costs and risks of localizing products for foreign countries; unexpected changes in regulatory requirements, tariffs and other trade barriers; difficulties and costs in the repatriation of earnings and burdens of complying with a wide variety of foreign laws.  

The vast majority of our sales outside of North America are denominated in local currencies, and accordingly, the U.S. dollar equivalent of these sales is affected by changes in the foreign currency exchange rates. The change in exchange rates had the effect of increasing our consolidated sales by $1.5 million in the three month period ended June 30, 2014, and decreasing our consolidated sales by $3.4 million in the three month period ended June 30, 2013. The change in exchange rates had the effect of decreasing our consolidated sales by $2.9 million in the six month period ended June 30, 2014, and decreasing our consolidated sales by $3.5 million in the six month period ended June 30, 2013. Since most of our international operating expenses are also incurred in local currencies, the change in exchange rates had the effect of increasing our consolidated operating expenses by $127,000 in the three month period ended June 30, 2014, and decreasing our consolidated operating expenses by $1.6 million in the three month period ended June 30, 2013.  The change in exchange rates had the effect of decreasing our consolidated operating expenses by $1.6 million in the six month period ended June 30, 2014, and decreasing our consolidated operating expenses by $928,000 in the six month period ended June 30, 2013.

During the three and six month periods ended June 30, 2014, there was mixed volatility in the exchange rates between the U.S. dollar and most of the major currencies in the markets in which we do business with strengthening of the U.S. dollar against currencies in emerging markets, particularly the Russian ruble, the Chinese yuan and the Hungarian forint along with a weakening of the U.S. dollar against the Euro and British pound.  We cannot predict to what degree or how long this volatility in the foreign currency exchange markets will continue. In the past, we have noted that significant volatility in foreign currency exchange rates in the markets in which we do business has had a significant impact on the revaluation of our foreign currency denominated firm commitments, on our ability to forecast our U.S. dollar equivalent revenues and expenses and on the effectiveness of our hedging programs. In the past, these dynamics have also adversely affected our revenue growth in international markets and may pose similar challenges in the future. We recognize the local currency as the functional currency in virtually all of our international subsidiaries.

If the local currencies in which we sell our products strengthen against the U.S. dollar, we may need to lower our prices in the local currency to remain competitive in our international markets which could have a material adverse effect on our gross and net profit margins. If the local currencies in which we sell our products weaken against the U.S. dollar and if the local sales prices cannot be raised due to competitive pressures, we will experience a deterioration of our gross and net profit margins. To help protect against the change in the value caused by a fluctuation in foreign currency exchange rates of forecasted foreign currency cash flows resulting from international sales and expenses over the next one to two years, we have a foreign currency cash flow hedging program. We hedge portions of our forecasted revenue, cost of sales and operating expenses denominated in foreign currencies with foreign currency forward 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 purchased option 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 option contracts designated as hedges, net of the premium paid. 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, and Hungarian forint) and limit the duration of these contracts to 40 months or less. As a result, our hedging activities only partially address our risks from foreign currency transactions, and there can be no assurance that this strategy will be successful. We do not invest in contracts for speculative purposes.  

During the three month period ended June 30, 2014, our hedges had the effect of decreasing our consolidated sales by $231,000, decreasing our cost of sales by $101,000 and decreasing our operating expenses by $86,000. During the six month period ended June 30, 2014, our hedges had the effect of increasing our consolidated sales by $115,000, decreasing our cost of sales by $182,000, and decreasing our operating expenses by $104,000. During the three month period ended June 30, 2013, our hedges had the effect of increasing our consolidated sales by $804,000, increasing our cost of sales by $34,000, and increasing our operating expenses by $9,000.During the six month period ended June 30, 2013, our hedges had the effect of increasing our consolidated sales by $2.0 million, decreasing our cost of sales by $74,000, and increasing our operating expenses by $10,000. (See Note 5 - Derivative instruments and hedging activities of Notes to Consolidated Financial Statements for further discussion regarding our cash flow hedging program and its related impacted on our consolidated sales, cost of sales and operating expenses for the three and six month periods ended June 30, 2014 and 2013).

Inventory Management  

The markets for our products dictate that many of our products be shipped very quickly after an order is received. As a result, we are required to maintain significant inventories. Therefore, inventory obsolescence is a risk for us due to frequent engineering changes, shifting customer demand, the emergence of new industry standards and rapid technological advances including the introduction by us or our competitors of products embodying new technology. However, our risk of obsolescence may be mitigated as many of our products have interchangeable parts and many have long lives. While we adjust for excess and obsolete inventories and we monitor the valuation of our inventories, there can be no assurance that our valuation adjustments will be sufficient.

In recent years, we have made a concentrated effort to increase our revenue through the pursuit of orders with a value greater than $1.0 million. Fulfillment of these contracts can severely challenge our supply chain capabilities at the component acquisition, assembly and delivery stages. These contracts can also require us to develop specific product mitigation plans for product delivery constraints caused by unexpected or catastrophic situations to help assure timely production recovery and to comply with critical delivery commitments where severe contractual liabilities can be imposed on us if we fail to provide the quantity of products at the required delivery times. In order to help mitigate the risks associated with these contractual requirements, we may choose to build inventory levels for certain parts or systems. Because our contracts with such customers may allow the customer to cancel or delay orders without liability, such actions expose our business to increased risk of inventory obsolescence.

Market Risk  

We are exposed to a variety of risks, including foreign currency fluctuations and changes in the market value of our investments. In the normal course of business, we employ established policies and procedures to manage our exposure to fluctuations in foreign currency values and changes in the market value of our investments.  

Cash, Cash Equivalents and Short-Term Investments  

At June 30, 2014, we had $402 million in cash, cash equivalents and short-term investments. See Liquidity and Capital Resourcesabove for further discussion regarding our cash, cash equivalents and short-term investments. 

We report our available-for-sale short-term investments at fair value. (See Note 4 – Fair value measurements of Notes to Consolidated Financial Statements for a further description of the fair value measurement of our short term investments).

The goal of our investment policy is to manage our investment portfolio to preserve principal and liquidity while maximizing the return on our investment portfolio through the full investment of available funds. We place our cash investments in instruments that meet credit quality standards, as specified in our corporate investment policy guidelines. These guidelines also limit the amount of credit exposure to any one issue, issuer or type of instrument. Our cash equivalents and short-term investments carried ratings from the major credit rating agencies that were in accordance with our corporate investment policy. Our investment policy allows investments in the following: government and federal agency obligations, repurchase agreements (“Repos”), certificates of deposit and time deposits, corporate obligations, medium term notes and deposit notes, commercial paper including asset-backed commercial paper (“ABCP”), puttable bonds, general obligation and revenue bonds, money market funds, taxable commercial paper, corporate notes/bonds, municipal notes, municipal obligations, variable rate demand notes and tax exempt commercial paper. All such instruments must carry minimum ratings of A1/P1/F1, MIG1/VMIG1/SP1 and A2/A/A, as applicable, all of which are considered “investment grade.” Our investment policy for marketable securities requires that all securities mature in three years or less, with a weighted average maturity of no longer than 18 months with at least 10% maturing in 90 days or less.

We account for our investments in debt and equity instruments under FASB ASC 320 Investments – Debt and Equity Securities (FASB ASC 320). Our investments are classified as available-for-sale and accordingly are reported at fair value, with unrealized gains and losses reported as other comprehensive income, a component of stockholders’ equity. 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 at June 30, 2014 and December 31, 2013 was $164 million and $163 million, respectively. 

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. There were not any other-than-temporary impairments recognized in other expense during the six month period ended June 30, 2014.

32

Interest Rate Risk  

Investments in both fixed rate and floating rate instruments carry a degree of interest rate risk. Fixed rate securities may have their market value adversely impacted due to an increase in interest rates, while floating rate securities may produce less income than expected if interest rates fall. Due to these factors, our future investment income may fall short of expectations due to changes in interest rates or if the decline in the fair value of our publicly traded debt investments is judged to be other-than-temporary. We may suffer losses in principal if we are forced to sell securities that have declined in market value due to changes in interest rates. However, because any debt securities we hold are classified as available-for-sale, no gains or losses are realized in our income statement due to changes in interest rates unless such securities are sold prior to maturity or unless declines in value are determined to be other-than-temporary. These securities are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of stockholders’ equity, net of tax.

In a declining interest rate environment, as short-term investments mature, reinvestment occurs at less favorable market rates. Given the short-term nature of certain of our investments, the current interest rate environment of low rates has negatively impacted our investment income.

In order to assess the interest rate risk associated with our investment portfolio, we performed a sensitivity analysis to determine the impact a change in interest rates would have on the value of our investment portfolio assuming a 100 basis point parallel shift in the yield curve. Based on our investment positions as of June 30, 2014, a 100 basis point increase or decrease in interest rates across all maturities would result in an $801,000 increase or decrease in the fair market value of our portfolio. As of December 31, 2013, a similar 100 basis point increase or decrease in interest rates across all maturities would result in a $796,000 increase or decrease in the fair market value of our portfolio. Such losses would only be realized if we sold the investments prior to maturity or if there is an other-than-temporary impairment. Actual future gains and losses associated with our investments may differ from the sensitivity analyses performed as of June 30, 2014, due to the inherent limitations associated with predicting the changes in the timing and level of interest rates and our actual exposures and positions.  

We continue to monitor the stability of the financial markets, particularly those in the European region and have taken steps to limit our direct and indirect exposure to these markets; however, we can give no assurance that we will not be negatively impacted by any adverse outcomes in those markets. We also continue to weigh the benefit of the higher yields associated with longer maturities against the interest rate risk and credit rating risk, also associated with these longer maturities when making these decisions. We cannot predict when or if interest rates and investment yields will rise. If yields continue to stay at these low levels, our investment income will continue to be negatively impacted.  

Exchange Rate Risk  

Our objective in managing our exposure to foreign currency exchange rate fluctuations is to reduce the impact of adverse fluctuations in such exchange rates on our earnings and cash flow. Accordingly, we utilize purchased foreign currency option and forward contracts to hedge our exposure on anticipated transactions and firm commitments. There can be no assurance that our foreign currency hedging activities will substantially offset the impact of fluctuations in currency exchanges rates on our results of operations and financial position. Based on the foreign exchange instruments outstanding at June 30, 2014 and December 31, 2013, an adverse change (defined as 20% in the Asian currencies and 10% in all other currencies) in exchange rates would result in a decline in the aggregate settlement value of all of our instruments outstanding of approximately $22 million and $15 million, respectively. However, as we utilize foreign currency instruments for hedging anticipated and firmly committed transactions, we believe that a loss in settlement value for those instruments will be substantially offset by increases in the value of the underlying exposure. (See Note 5 - Derivative instruments and hedging activities of Notes to Consolidated Financial Statements for a further description of our derivative instruments and hedging activities).

Item 4.Controls and Procedures  

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, our Chief Executive Officer, Dr. James Truchard, and our Executive Vice President, Chief Operating Officer and Chief Financial Officer, Alex Davern, based on their evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended), required by paragraph (b) of Rule 13a – 15 or Rule 15d – 15, have concluded that our disclosure controls and procedures were effective at the reasonable assurance level, to ensure the timely collection, evaluation and disclosure of information relating to us that would potentially be subject to disclosure under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder, and that such information is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. These disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file or submit is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our disclosure controls and procedures include components of our internal control over financial reporting. Our assessment of the effectiveness of our internal control over financial reporting is expressed at the level of reasonable assurance because a control system, no matter how well designed and operated, can provide only reasonable, but not absolute assurance that the control system’s objectives will be met.    

Changes in Internal Control Over Financial Reporting

We continue to enhance our internal control over financial reporting in key functional areas with the goal of monitoring our operations at the level of documentation, segregation of duties, and systems security necessary, as well as transactional control procedures required, under Auditing Standard No. 5 issued by the Public Company Accounting Oversight Board. We discuss and disclose these matters to the audit committee of our board of directors and to our auditors.  

During the three month period ended June 30, 2014, there were no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of the Rule 13a – 15 or Rule 15d – 15 that have materially affected, or are likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1.       LEGAL PROCEEDINGS

We are not currently a party to any material litigation. However, in the ordinary course of our business, we are involved in a limited number of legal actions, both as plaintiff and defendant, and could incur uninsured liability in any one or more of them. We also periodically receive notifications from various third parties related to alleged infringement of patents or intellectual property rights, commercial disputes or other matters. No assurances can be given with respect to the extent or outcome of any future litigation or dispute.  

ITEM 1A.    RISK FACTORS

Uncertain Global Economic Conditions Could Materially Adversely Affect Our Business and Results of Operations.Our operations and performance are sensitive to fluctuations in general economic conditions, both in the U.S. and globally. We remain concerned with some economic and political events we saw during the first half of 2014. Of particular concern are the most recent sanctions against Russia by the European Union (EU) and the U.S. Such sanctions may limit access by Russian financial institutions to capital markets, impose embargoes on certain goods, or restrict sales of sensitive technologies, which alone or in combination may have a material adverse effect on our revenues and the financial results of our operations. In addition, we remain concerned about the geopolitical instability in the Middle East as well as the continued volatility of the currency markets in the emerging economies which could negatively impact the broader industrial economy. Other factors that could adversely influence demand for our products include increases in fuel and other energy costs, unemployment, labor and healthcare costs, access to credit, consumer and business confidence, and other macroeconomic factors affecting spending behavior.

Historically, our business cycles have generally followed the expansion and contraction cycles in the global industrial economy as measured by the PMI. In the three months ended June 30, 2014, the average of the PMI was 52.2 and the average of the new order element of the PMI was 53.3, both indicating expansion. During the three month period ended June 30, 2014, the PMI in the U.S. and the Eurozone maintained readings above 50. We are unable to predict whether the industrial economy, as measured by the PMI, will remain above the neutral reading of 50, strengthen or contract during the remainder of 2014. If the industrial economy as measured by the PMI begins to contract, it could have an adverse effect on the spending patterns of businesses including our current and potential customers which could adversely affect our revenues and result of operations.

Revenue Derived from Large Orders Could Adversely Affect our Gross Margin and Could Lead to Greater Variability in our Quarterly Results.We define our large order business as orders with a value greater than $100,000. As a percent of our overall business, orders over $100,000 represented 26% and 21% of our total orders during the three month periods ended June 30, 2014 and 2013, respectively, and 23% and 22% in the six month periods ended June 30, 2014 and 2013, respectively. These orders may be more sensitive to changes in the global industrial economy, may be subject to greater discount variability, lower gross margins, and may contract at a faster pace during an economic downturn. For example, excluding the impact of our largest customer, large orders grew by 22% and 10% in three and six month periods ended June 30, 2014 compared to growth rates of 1% and 17% during the three and six month periods ended June 30, 2013. Historically, our gross margins have been relatively stable from period to period. To the extent that the amount of our revenue derived from larger orders increases in future periods, either in absolute dollars or as a percentage of our overall business, our gross margins could decline, and we could experience greater volatility and see a greater negative impact from future downturns in the global industrial economy. This dynamic may also have an adverse effect on the historical seasonal pattern of our revenues and our results of operations. These types of orders also make managing inventory levels more difficult as we have in the past and may have to in the future build large quantities of inventory in anticipation of future demand that may not materialize.

35

Orders With a Value of Greater than One Million Dollars Expose Us to Significant Additional Business and Legal Risks that Could Have a Material Adverse Impact on our Business, Results of Operations and Financial Condition. In recent years, we have made a concentrated effort to increase our revenue through the pursuit of orders with a value greater than $1.0 million. During the three month periods ended June 30, 2014 and 2013, we received $27 million and $13 million, respectively, in new orders from our largest customer. In the three month periods ended June 30, 2014 and 2013, we recognized net revenue of $20 million and $23 million, respectively, from these orders. During the six month periods ended June 30, 2014 and 2013, we received $39 million and $30 million in orders from our largest customer, respectively, and in the same periods we recognized $27 million and $27 million from this customer, respectively. These types of orders expose us to significant additional business and legal risks compared to smaller orders. Our very large customers frequently require contract terms that vary substantially from our standard terms of sale. These orders can be accompanied by critical delivery commitments and severe contractual liabilities can be imposed on us if we fail to provide the quantity of product at the required delivery times. These customers may also impose product acceptance requirements and product performance evaluations which create uncertainty with respect to the timing of our ability to recognize revenue from such orders. In addition, these larger orders are more volatile, are subject to greater discount variability and may contract at a faster pace during an economic downturn. These contracts may also have supply constraint requirements which mandate that we allocate large product inventories for a specific contract. These inventory requirements expose us to higher risks of inventory obsolescence and can adversely impact our ability to provide adequate product supply to other customers.

Fulfillment of these contracts can severely challenge our supply chain capabilities at the component acquisition, assembly and delivery stages. Our contracts with such customers may allow the customer to cancel or delay orders without liability which exposes our business and financial results to significant risk. These contracts can require us to develop specific product mitigation plans for product delivery constraints caused by unexpected or catastrophic situations to help assure quick production recovery. We can attempt to manage this risk but there can be no assurance that we will be successful in our efforts. These customers may demand most favored customer pricing, significant discounts, extended payment terms and volume rebates and such terms can adversely impact our revenues, margins and financial results and may also negatively impact our days sales outstanding as these orders become a larger proportion of our overall revenue. These customers may request broad indemnity obligations and large direct and consequential damage provisions in the event their contracts with us are breached, and these provisions may expose us to risk and liabilities in excess of our standard terms and conditions of sale. While we attempt to limit the number of contracts that contain the non-standard terms of sale described above and attempt to contractually limit our potential liability under such contracts, we have been and expect to be required to agree to some or all of such provisions to secure these customers and to continue to grow our business. Such actions expose us to significant additional risks which could result in a material adverse impact on our business, results of operations and financial condition.

Our Product Revenues are Dependent on Certain Industries and Contractions in these Industries Could Have a Material Adverse Effect on Our Results of Operations.Sales of our products are dependent on customers in certain industries, particularly the telecommunications, semiconductor, consumer electronics, automotive, automated test equipment, defense and aerospace industries. As we have experienced in the past, and as we may continue to experience in the future, downturns characterized by diminished product demand in any one or more of these industries may result in decreased sales, and a material adverse effect on our operating results. For example, personal computer (“PC”) shipments declined for eight straight quarters through the first quarter of 2014 and, during the first quarter of 2014, Sony announced that it would exit the PC business by the end of 2014. However, we have noted reports indicating improvement during the second quarter of 2014 in PC sales, including sizeable shipment increases for the three largest PC makers as well as a slightly improved 2014 full year outlook by Intel. We cannot predict whether the reported improvement in the PC industry will continue through the remainder of 2014. As we have noted in the past, contractions in the PC industry may have a material negative impact on our business as they may negatively impact the spending and investment patterns of many of the customers we serve.

Our Current Domestic Cash Position May Not Be Sufficient to Fund our Domestic Cash Needs in the Next Twelve Months and We May Need to Seek Funding from External Sources or Repatriate Foreign Earnings.  At June 30, 2014, we had $402 million in cash, cash equivalents and short-term investments of which $340 million was held in operating and investment accounts of our foreign subsidiaries. On May 9, 2013, we entered into a Loan Agreement (the “Loan Agreement”) with Wells Fargo Bank, National Association. The Loan Agreement provides for a $50 million unsecured revolving line of credit with a scheduled maturity date of May 9, 2018 (the “Maturity Date”). Proceeds of loans made under the Loan Agreement may be used for working capital and other general corporate purposes. We may choose to borrow funds against this line of credit in future periods in order to have sufficient domestic cash to fund continued dividends to our stockholders, to fund potential acquisitions or other domestic general corporate purposes without the need to repatriate foreign earnings. At June 30, 2014, we did not have any amounts outstanding or due as a result of borrowings under this line of credit.

36

We may also seek to pursue additional financing or to raise additional funds by selling equity or debt to the public or in private transactions. If we elect to raise additional funds, we may not be able to obtain such funds on a timely basis on acceptable terms, if at all. If we raise additional funds by issuing additional equity or convertible debt securities, the ownership percentages of our existing stockholders would be reduced. In addition, the equity or debt securities that we issue may have rights, preferences or privileges senior to those of our common stock. We may also choose to repatriate foreign earnings which would be subject to the U.S. federal statutory tax rate of 35% and therefore, would likely have a material adverse effect on our effective tax rate and on our net income and earnings per share. We could also choose to reduce certain expenditures or payments of dividends or suspend our program to repurchase shares of our common stock. Historically, we have not had to rely on debt, public or private, to fund our operating, financing or investing activities.

Our Success Depends on New Product Introductions and Market Acceptance of Our Products.The market for our products is characterized by rapid technological change, evolving industry standards, changes in customer needs and frequent new product introductions, and is therefore highly dependent upon timely product innovation. Our success is dependent on our ability to successfully develop and introduce new and enhanced products on a timely basis to replace declining revenues from older products, and on increasing penetration in domestic and international markets. As has occurred in the past and as may be expected to occur in the future, we have experienced significant delays between the announcement and the commercial availability of new products. Any significant delay in releasing new products could have a material adverse effect on the ultimate success of a product and other related products and could impede continued sales of predecessor products, any of which could have a material adverse effect on our operating results. There can be no assurance that we will be able to introduce new products in accordance with announced release dates, that our new products will achieve market acceptance or that any such acceptance will be sustained for any significant period. Failure of our new products to achieve or sustain market acceptance could have a material adverse effect on our operating results. Moreover, there can be no assurance that our international sales will continue at existing levels or grow in accordance with our efforts to increase foreign market penetration.

We Operate in Intensely Competitive Markets.The markets in which we operate are characterized by intense competition from numerous competitors, some of which are divisions of large corporations having far greater resources than we have, and we may face further competition from new market entrants in the future. A key competitor is Agilent Technologies Inc. (“Agilent”). In 2013, Agilent announced plans to separate into two publicly traded companies; one in life sciences, diagnostics and applied markets that will retain the Agilent name and Keysight Technologies that will concentrate solely on the electronic measurement industry. Agilent has stated that it expects to complete the spin off of Keysight Technologies in the fall of 2014. Agilent offers hardware and software products that provide solutions that directly compete with our virtual instrumentation products and Agilent has released its own line of PXI based hardware. Agilent is aggressively advertising and marketing products that are competitive with our products. Because of Agilent’s strong position in the instrumentation business, changes in its marketing strategy or product offerings could have a material adverse effect on our operating results.  We cannot predict the impact Agilent’s spin off of Keysight Technologies will have on the markets that we serve.

We believe our ability to compete successfully depends on a number of factors both within and outside our control, including: 

· our ability to maintain and grow our business with our very large customers;

· general market and economic conditions;

· our ability to meet the volume and service requirements of our very large customers;

· industry consolidation, including acquisitions by our competitors;

· capacity utilization and the efficiency of manufacturing operations;  

· success in developing new products;

· timing of our new product introductions; 

· new product introductions by competitors; 

· the ability of competitors to more fully leverage low cost geographies for manufacturing and/or distribution; 

· product pricing; 

· effectiveness of sales and marketing resources and strategies; 

· adequate supply of components and materials; 

· strategic relationships with our suppliers; 

· product quality and performance; 

· protection of our products by effective use of intellectual property laws; 

· the financial strength of our competitors; 

· the outcome of any future litigation or commercial dispute; 

· barriers to entry imposed by competitors with significant market power in new markets; and, 

· government actions throughout the world. 

There can be no assurance that we will be able to compete successfully in the future.  

37

 We Have Established a Budget and Variations From Our Budget Will Affect Our Financial Results.We have an operating budget for 2014. Our budget was established based on the estimated revenue from sales of our products which are based on anticipated economic conditions in the markets in which we do business as well as the timing and volume of our new products and the expected penetration of both new and existing products in the marketplace. If demand for our products in the remainder of 2014 is less than the demand we anticipated in setting our 2014 budget, our operating results could be negatively impacted.

If we exceed our budgeted level of expenses or if we cannot reduce expenditures in response to a decrease in revenue, our operating results could be adversely affected. Our spending could exceed our budget due to a number of factors, including:

· less than expected capacity utilization of our new manufacturing facility in Penang, Malaysia;

· inefficiencies related to start-up operations of our new manufacturing facility in Penang, Malaysia;

· increased manufacturing costs resulting from component supply shortages or component price fluctuations; 

· additional marketing costs for new product introductions or for conferences and tradeshows; 

· the timing, cost or outcome of any future intellectual property litigation or commercial disputes;

· increased component costs resulting from vendors increasing their sales price; or 

· additional costs related to acquisitions, if any.  

Our Quarterly Results are Subject to Fluctuations Due to Various Factors that May Adversely Affect Our Business and Result of Operations.  Our quarterly operating results have fluctuated in the past and may fluctuate significantly in the future due to a number of factors, including: 

· changes in the global economy or global credit markets, particularly in the Euro zone; 

· increasing concentration in the amount of revenue derived from very large orders and the pricing, margins, and other terms of such orders; 

· fluctuations in foreign currency exchange rates; 

· changes in the mix of products sold; 

· the availability and pricing of components from third parties (especially limited sources); 

· the difficulty in maintaining margins, including the higher margins traditionally achieved in international sales; 

· changes in pricing policies by us, our competitors or suppliers; 

· the timing, cost or outcome of any future intellectual property litigation or commercial disputes; 

· delays in product shipments; and, 

· disruptions in transportation channels.  

We are Subject to Various Risks Associated with International Operations and Foreign Economies. Our international sales are subject to inherent risks, including:  

· fluctuations in foreign currencies relative to the U.S. dollar;

· difficulties and the high tax costs associated with the repatriation of earnings;  

· fluctuations in local economies;  

· difficulties in staffing and managing foreign operations;  

· greater difficulty in accounts receivable collection;  

· costs and risks of localizing products for foreign countries;  

· unexpected changes in regulatory requirements;  

· tariffs and other trade barriers; and,  

· the burdens of complying with a wide variety of foreign laws.  

In many foreign countries, particularly in those with developing economies, it is common to engage in business practices that are prohibited by U.S. regulations applicable to us such as the Foreign Corrupt Practices Act. Although we have policies and procedures designed to ensure compliance with these laws, there can be no assurance that all of our employees, contractors and agents, including those based in or from countries where practices which violate such U.S. laws may be customary, will not take actions in violation of our policies. Any violation of foreign or U.S. laws by our employees, contractors or agents, even if such violation is prohibited by our policies, could have a material adverse effect on our business. We must also comply with various import and export regulations. The application of these various regulations depends on the classification of our products which can change over time as such regulations are modified or interpreted. As a result, even if we are currently in compliance with applicable regulations, there can be no assurance that we will not have to incur additional costs or take additional compliance actions in the future. Failure to comply with these regulations could result in fines or termination of import and export privileges, which could have a material adverse effect on our operating results. Additionally, the regulatory environment in some countries is very restrictive as their governments try to protect their local economy and value of their local currency against the U.S. dollar.

38

The vast majority of our sales outside of North America are denominated in local currencies, and accordingly, the U.S. dollar equivalent of these sales is affected by changes in the foreign currency exchange rates. (See Financial Risk Management under Item 3. Quantitative and Qualitative Disclosures About Market Risk for further discussion on the effect changes in the foreign currency exchange rates have on our operating results.)  

During the three and six month periods ended June 30, 2014, there was mixed volatility in the exchange rates between the U.S. dollar and most of the major currencies in the markets in which we do business with strengthening of the U.S. dollar against currencies in emerging markets, particularly the Russian ruble, the Chinese yuan and the Hungarian forint along with a weakening of the U.S. dollar against the Euro and British pound We cannot predict to what degree or how long this volatility in the foreign currency exchange markets will continue. In the past, we have noted that significant volatility in foreign currency exchange rates in the markets in which we do business has had a significant impact on the revaluation of our foreign currency denominated firm commitments, on our ability to forecast our U.S. dollar equivalent revenues and expenses and on the effectiveness of our hedging programs. In the past, these dynamics have also adversely affected our revenue growth in international markets and may pose similar challenges in the future. We recognize the local currency as the functional currency in virtually all of our international subsidiaries.

Our Tax Returns and Other Tax Matters are Subject to Examination by the U.S. Internal Revenue Service and Other Tax Authorities and Governmental Bodies and the Results of These Examinations Could Have a Material Adverse Effect on Our Financial Condition. We account for uncertainty in income taxes recognized in our financial statements using prescribed recognition thresholds and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on our tax returns. These uncertain tax positions are subject to examination by the U.S. Internal Revenue Service and other tax authorities. The Internal Revenue Service (“IRS”) commenced an examination of our U.S. income tax returns for 2010 and 2011 in the second quarter of 2013 and such examination was not complete as of June 30, 2014.  However, in July 2014, we agreed to the IRS findings. Although such matter is still subject to final processing by the IRS, we believe the chance of further changes to the current IRS findings for 2010 and 2011 is remote and such matter is effectively settled. Accordingly, we anticipate recognizing tax benefits of $13.9 million in the three month period ended September 30, 2014 related to 2010 and 2011 intercompany transfer pricing activity. There can be no assurance as to the outcome of any future examinations. If the ultimate determination of our taxes owed is for an amount in excess of amounts previously accrued, our operating results, cash flows, and financial condition could be materially adversely affected.

Tax Law Changes in U.S. Could Have a Negative Impact on our Effective Tax Rate, Earnings and Results of Operations. In 2013, our effective tax rate benefited from the research tax credit in the U.S. This credit expired at the end of 2013 and unless it is extended, we will not be able to take this credit in 2014 or beyond which will have a material negative impact on our effective tax rate in future periods.

Tax Law Changes in Hungary Could Have a Negative Impact on our Effective Tax Rate, Earnings and Results of Operations. The profit from our Hungarian operation benefits from the fact that it is subject to an effective income tax rate that is lower than the U.S. federal statutory tax rate of 35%. Our earnings in Hungary are subject to a statutory tax rate of 19%. The difference between this rate and the statutory U.S. rate of 35% resulted in income tax benefits of $2.4 million and $1.5 million for the three month periods ended June 30, 2014 and 2013, respectively, and income tax benefits of $4.0 million and $3.2 million for the six month periods ended June 30, 2014 and 2013, respectively. In addition, effective January 1, 2010, certain qualified research and development expenses in Hungary became eligible for an enhanced tax deduction. The enhanced tax deduction for research and development expenses resulted in income tax benefits of $3.2 million and $2.3 million for the three month periods ended June 30, 2014 and 2013, respectively, and income tax benefits of $5.8 million and $4.7 million for the six month periods ended June 30, 2014 and 2013, respectively. This tax benefit may not be available in future years due to changes in political conditions in Hungary or changes in tax laws in Hungary and in the U.S. The reduction or elimination of these benefits in Hungary or future changes in U.S. law pertaining to the taxation of foreign earnings could result in an increase in our future effective income tax rate which could have a material adverse effect on our operating results. No countries other than Hungary had a significant impact on our effective tax rate. We have not entered into any advanced pricing or other agreements with the IRS with regard to any foreign jurisdictions.

Our Income Tax Rate could be Affected by the Expiration of a Tax Holiday in Malaysia. Potential future profits from our new manufacturing facility in Penang, Malaysia are free of tax under a 15 year tax holiday effective January 1, 2013. The tax holiday resulted in an income tax benefit of $6,000 and $311,000 for the three and six month periods ended June 30, 2014, respectively. If we fail to satisfy the conditions of the tax holiday, this tax benefit may be terminated early. The expiration of the tax holiday in Malaysia or future changes in U.S. law pertaining to the taxation of foreign earnings could have a material adverse effect on our operating results.

A Substantial Majority of our Manufacturing, Warehousing and Distribution Capacity is Located Outside of the United States. Our Hungarian manufacturing and warehouse facility sourced a substantial majority of our sales in 2012. In 2013, we transitioned some of this capacity to our manufacturing, warehouse and distribution facility in Penang, Malaysia and this transition is continuing in 2014. In addition, production, primarily of RF products and of low volume, complex or newly introduced products done in Austin, Texas, and this productionwill be transitioning to our manufacturing facilities in Hungary and Malaysia over the next 12 to 18 months.

In order to enable timely shipment of products to our customers we also maintain the vast majority of our inventory at our international locations. In addition to being subject to the risks of maintaining such a concentration of manufacturing capacity and global inventory, these facilities and their operations are also subject to risks associated with doing business internationally, including:

· a changing and potentially unstable political environment; 

· significant and frequent changes in the corporate tax law; 

· the volatility of the Hungarian forint and the Malaysian ringgit relative to the U.S. dollar; 

· difficulty in managing manufacturing operations in foreign countries; 

· challenges in expanding capacity to meet increased demand; 

· difficulty in achieving or maintaining product quality; 

· interruption to transportation flows for delivery of components to us and finished goods to our customers; 

· a restrictive labor code; and, 

· increasing labor costs. 

 No assurance can be given that our efforts to mitigate these risks will be successful. Any failure to effectively deal with the risks above could result in an interruption in the operations of our facilities in Hungary or Malaysia which could have a material adverse effect on our operating results.

Our centralization of inventory and distribution from a limited number of shipping points is subject to inherent risks, including:

· burdens of complying with additional and/or more complex VAT and customs regulations; and, 

· concentration of inventory increasing the risks associated with fire, natural disasters and logistics disruptions to customer order fulfillment. 

Any difficulties with the centralization of our distribution or delays in the implementation of the systems or processes to support this centralized distribution could result in an interruption of our normal operations, including our ability to process orders and ship products to our customers. Any failure or delay in distribution from our facilities in Hungary and Malaysia could have a material adverse effect on our operating results.

Our Manufacturing Facility in Penang, Malaysia Could Adversely Affect our Gross Margin, Results of Operations and Earnings if Anticipated Demand is Not Achieved.Our new facility in Malaysia is intended to support our long term manufacturing and warehousing capacity needs. We are currently in the process of ramping up production at our manufacturing site in Penang, Malaysia. During 2014, we expect this site will produce around 20% to 30% of our total production, focused primarily on making existing products which will be transferred from our Hungarian production facility to support anticipated growth in our business. However, if demand for our products does not grow as expected or if it contracts in future periods, we will have excess warehousing and manufacturing capacity which will cause an increase in overhead that will likely negatively impact our gross margins and results of operations in future periods. In addition, we could experience other cost overruns with respect to our Malaysian facility including those associated with;

· inefficiencies related to start-up operations of this facility;

· cost overruns related to training a new workforce for this facility; or

· inefficient inventory management.

Our Revenues are Subject to Seasonal Variations.In previous years, our revenues have been characterized by seasonality, with revenues typically growing from the first quarter to the second quarter, being relatively constant from the second quarter to the third quarter, growing in the fourth quarter compared to the third quarter and declining in the first quarter of the following year from the fourth quarter of the preceding year. This historical trend has been affected and may continue to be affected in the future by broad fluctuations in the global industrial economy as well as the timing of new product introductions or any acquisitions. In addition, revenue derived from very large orders, including those from our largest customer, have had a significant impact on our historical seasonal trends as these orders may be more sensitive to changes in the global industrial economy, may be subject to greater volatility in timing and amount, greater discount variability, lower gross margins, and may contract at a faster pace during economic downturns.

40

Our Business is Dependent on Key Suppliers and Distributors and Disruptions in these Businesses Could Adversely Affect our Business and Results of Operations.Our manufacturing processes use large volumes of high-quality components and subassemblies supplied by outside sources. Several of these components are only available through limited sources. Limited source components purchased include custom application specific integrated circuits (“ASICs”), chassis and other components. We have in the past experienced delays and quality problems in connection with limited source components, and there can be no assurance that these problems will not recur in the future. Accordingly, our failure to receive components from limited suppliers could result in a material adverse effect on our revenues and operating results. In the event that any of our limited source suppliers experience significant financial or operational difficulties due to adverse global economic conditions or otherwise, our business and operating results would likely be adversely impacted until we are able to secure another source for the required materials.

In some countries, we use distributors to support our sales channels. In the event that any of our distributors experience significant financial or operational difficulties due to adverse global economic conditions or if we experience disruptions in the use of these distributors, our business and operating results would likely be adversely impacted until we are able to secure another distributor or establish direct sales capabilities in the affected market.

We May Experience Component Shortages that May Adversely Affect Our Business and Result of Operations.As has occurred in the past and as may be expected to occur in the future, supply shortages of components used in our products, including limited source components, can result in significant additional costs and inefficiencies in manufacturing. If we are unsuccessful in resolving any such component shortages in a timely manner, we will experience a significant impact on the timing of revenue, a possible loss of revenue, and/or an increase in manufacturing costs, any of which would have a material adverse impact on our operating results.

Concentrations of Credit Risk and Uncertain Conditions in the Global Financial Markets May Adversely Affect Our Business and Result of Operations.By virtue of our holdings of cash, investment securities and foreign currency derivatives, we have exposure to many different counterparties, and routinely execute transactions with counterparties in the financial services industry, including commercial banks and investment banks. Many of these transactions expose us to credit risk in the event of a default of our counterparties. We continue to monitor the stability of the financial markets, particularly those in the European region and have taken steps to limit our direct and indirect exposure to these markets; however, we can give no assurance that we will not be negatively impacted by any adverse outcomes in those markets. There can be no assurance that any losses or impairments to the carrying value of our financial assets as a result of defaults by our counterparties, would not materially and adversely affect our business, financial position and results of operations.

We Rely on Management Information Systems and Interruptions in our Information Technology Systems Could Adversely Affect our Business.We rely on the efficient and uninterrupted operation of complex information technology systems and networks to operate our business. We rely on a primary global center for our management information systems and on multiple systems in branches not covered by our global center. As with any information system, unforeseen issues may arise that could affect our ability to receive adequate, accurate and timely financial information, which in turn could inhibit effective and timely decisions. Furthermore, it is possible that our global center for information systems or our branch operations could experience a complete or partial shutdown. A significant system or network disruption could be the result of new system implementations, computer viruses, security breaches, facility issues or energy blackouts. If such a shutdown or disruption occurred, it would adversely impact our product shipments and revenues, as order processing and product distribution are heavily dependent on our management information systems. Such an interruption could also result in a loss of our intellectual property or the release of sensitive competitive information or partner, customer or employee personal data. Any loss of such information could harm our competitive position, result in a loss of customer confidence, and cause us to incur significant costs to remedy the damages caused by the disruptions or security breaches. Accordingly, our operating results in such periods would be adversely impacted.

We are continually working to maintain reliable systems to control costs and improve our ability to deliver our products in our markets worldwide. Our efforts include, but are not limited to following: firewalls, antivirus protection, patches, log monitors, routine backups with offsite retention of storage media, system audits, data partitioning and routine password modifications. No assurance can be given that our efforts will be successful.

We are Subject to Risks Associated with Our Website.We devote significant resources to maintain our Website, ni.com, as a key marketing, sales and support tool and expect to continue to do so in the future. However, there can be no assurance that we will be successful in our attempt to leverage the Web to increase sales. Failure to properly maintain our website may interrupt normal operations, including our ability to provide quotes, process orders, ship products, provide services and support to our customers, bill and track our customers, fulfill contractual obligations and otherwise run our business which would have a material adverse effect on our results of operations. We host our Website internally. Any failure to successfully maintain our Website or any significant downtime or outages affecting our Website could have a material adverse impact on our operating results.

41

Adoption of Complex Health Care Legislation and Related Regulations and Financial Reform Could Increase our Operating Costs and Adversely Affect Our Result of Operations.The adoption of the Patient Protection and Affordable Care Act and the related reconciliation measure, the Health Care and Education Reconciliation Act of 2010, and the regulations resulting from such legislation have increased the costs of providing health care to our employees as well as caused us to incur additional administrative burdens and costs to comply with certain provisions of this legislation. We are unable to predict the ultimate amount or timing of any such increased costs or to what extent we may need to divert other resources to comply with various provisions of this legislation. Additionally, the Dodd-Frank Wall Street Reform and Consumer Protection Act has resulted in increased costs to us as a result of fees as well as incremental efforts we have had to undertake to comply with provisions of this law which are applicable to our derivative contracts or other financial instruments. In addition to the fees and efforts we have already incurred and undertaken to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act, we may incur additional costs in future periods as new rules are published and become effective.

Our Products are Complex and May Contain Bugs or Errors.  As has occurred in the past and as may be expected to occur in the future, our new software products or new operating systems of third parties on which our products are based often contain bugs or errors that can result in reduced sales or cause our support costs to increase, either of which could have a material adverse impact on our operating results.

Our Business Depends on Our Proprietary Rights and We Have Been Subject to Intellectual Property Litigation. Our success depends on our ability to obtain and maintain patents and other proprietary rights relative to the technologies used in our principal products. Despite our efforts to protect our proprietary rights, unauthorized parties may have in the past infringed or violated certain of our intellectual property rights. We from time to time engage in litigation to protect our intellectual property rights. In monitoring and policing our intellectual property rights, we have been and may be required to spend significant resources. We from time to time may be notified that we are infringing certain patent or intellectual property rights of others. There can be no assurance that any future intellectual property dispute or litigation will not result in significant expense, liability, injunction against the sale of some of our products, and a diversion of management’s attention, any of which may have a material adverse effect on our operating results.

Our Reported Financial Results May be Adversely Affected by Changes in Accounting Principles Generally Accepted in the United States.We prepare our financial statements in conformity with accounting principles generally accepted in the U.S. These accounting principles are subject to interpretation by the Financial Accounting Standards Board and the Securities and Exchange Commission. A change in these policies or interpretations could have a significant effect on our reported financial results, and could affect the reporting of transactions completed before the announcement of a change.

Our Business Depends on the Continued Service of Key Management and Technical Personnel.  Our success depends upon the continued contributions of our key management, sales, marketing, research and development and operational personnel, including Dr. Truchard, our Chairman and Chief Executive Officer, and other members of our senior management and key technical personnel. We have no agreements providing for the employment of any of our key employees for any fixed term and our key employees may voluntarily terminate their employment with us at any time. The loss of the services of one or more of our key employees in the future could have a material adverse effect on our operating results. We also believe our future success will depend upon our ability to attract and retain additional highly skilled management, technical, marketing, research and development, and operational personnel with experience in managing large and rapidly changing companies, as well as training, motivating and supervising employees. Failure to attract and retain a sufficient number of our key personnel could have a material adverse effect on our operating results.

Our Manufacturing Operations are Subject to a Variety of Environmental Regulations and Costs that May Have a Material Adverse Effect on our Business and Results of our Operations.We must comply with many different governmental regulations related to the use, storage, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in our manufacturing operations in the U.S., Hungary, and Malaysia. Although we believe that our activities conform to presently applicable environmental regulations, our failure to comply with present or future regulations could result in the imposition of fines, suspension of production or a cessation of operations. Any such environmental regulations could require us to acquire costly equipment or to incur other significant expenses to comply with such regulations. Any failure by us to control the use of or adequately restrict the discharge of hazardous substances could subject us to future liabilities.

42

Our Acquisitions are Subject to a Number of Related Costs and Challenges that Could Have a Material Adverse Effect on Our Business and Results of Operations.  In recent years, we completed several acquisitions. Achieving the anticipated benefits of an acquisition depends upon whether the integration of the acquired business, products or technology is accomplished efficiently and effectively. In addition, successful acquisitions generally require, among other things, integration of product offerings, manufacturing operations and coordination of sales and marketing and R&D efforts. These difficulties can become more challenging due to the need to coordinate geographically separated organizations, the complexities of the technologies being integrated, and the necessities of integrating personnel with disparate business backgrounds and combining different corporate cultures. The integration of operations following an acquisition also requires the dedication of management resources, which may distract attention from our day-to-day business and may disrupt key R&D, marketing or sales efforts. Our inability to successfully integrate any of our acquisitions could harm our business. The existing products previously sold by entities we have acquired may be of a lesser quality than our products and/or could contain errors that produce incorrect results on which users rely or cause failure or interruption of systems or processes that could subject us to liability claims that could have a material adverse effect on our operating results or financial position. Furthermore, products acquired in connection with acquisitions may not gain acceptance in our markets, and we may not achieve the anticipated or desired benefits of such transactions.

We Are Subject to the Risk of Product Liability Claims.Our products are designed to provide information upon which users may rely. Our products are also used in “real time” applications requiring extremely rapid and continuous processing and constant feedback. Such applications give rise to the risk that a failure or interruption of the system or application could result in economic damage or bodily harm. We attempt to assure the quality and accuracy of the processes contained in our products, and to limit our product liability exposure through contractual limitations on liability, limited warranties, express disclaimers and warnings as well as disclaimers contained in our “shrink wrap” license agreements with end-users. If our products contain errors that produce incorrect results on which users rely or cause failure or interruption of systems or processes, customer acceptance of our products could be adversely affected. Further, we could be subject to liability claims that could have a material adverse effect on our operating results or financial position. Although we maintain liability insurance for product liability matters, there can be no assurance that such insurance or the contractual limitations used by us to limit our liability will be sufficient to cover or limit any claims which may occur.

Provisions in Our Charter Documents and Delaware Law May Delay or Prevent an Acquisition of Us. Our certificate of incorporation and bylaws and Delaware law contain provisions that could make it more difficult for a third party to acquire us without the consent of our Board of Directors. These provisions include a classified Board of Directors, prohibition of stockholder action by written consent, prohibition of stockholders to call special meetings and the requirement that the holders of at least 80% of our shares approve any business combination not otherwise approved by two-thirds of the Board of Directors. Delaware law also imposes some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock. In addition, our Board of Directors has the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer.

Compliance With Sections 302 and 404 of the Sarbanes-Oxley Act of 2002 is Costly and Challenging.  As required by Section 302 of the Sarbanes-Oxley Act of 2002, this Form 10-Q contains our management’s certification of adequate disclosure controls and procedures as of June 30, 2014. Our most recent annual report on Form 10-K also contains a report by our management on our internal control over financial reporting including an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2013. Our most recent annual report on Form 10-K also contains an attestation and report by our external auditors with respect to the effectiveness of our internal control over financial reporting under Section 404. While these assessments and reports did not reveal any material weaknesses in our internal control over financial reporting, compliance with Sections 302 and 404 is required for each future fiscal year end. We expect that the ongoing compliance with Sections 302 and 404 will continue to be both very costly and very challenging and there can be no assurance that material weaknesses will not be identified in future periods. Any adverse results from such ongoing compliance efforts could result in a loss of investor confidence in our financial reports and have an adverse effect on our stock price.

ITEM 2.UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

We did not repurchase any shares of common stock during the second quarter of 2014. At June 30, 2014, there were 3,932,245 shares available for repurchase under a repurchase plan approved on April 21, 2010. This repurchase plan does not have an expiration date.

ITEM 5.OTHER INFORMATION

From time to time our directors, executive officers and other insiders may adopt stock trading plans pursuant to Rule 10b5-1(c) promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended. Jeffrey L. Kodosky and James J. Truchard have made periodic sales of our stock pursuant to such plans.

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

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 (“RSUs”), is computed using the treasury stock method.  

The reconciliation of the denominators used to calculate basic EPS and diluted EPS for the three and six month periods ended June 30, 2014 and 2013, are as follows:

	Three Months Ended June 30,		Six Months Ended June 30,
	(In thousands)		(In thousands)
	(Unaudited)		(Unaudited)
	2014	2013	2014	2013
Weighted average shares outstanding-basic	126,887	124,377	126,433	123,845
Plus: Common share equivalents
Stock options, RSUs	625	893	690	979
Weighted average shares outstanding-diluted	127,512	125,270	127,123	124,824

Stock awards to acquire 13,500 shares and 538,100 shares for the three month periods ended June 30, 2014 and 2013, respectively, and 29,400 and 183,500 shares for the six month periods ended June 30, 2014 and 2013, respectively, were excluded in the computations of diluted EPS because the effect of including the stock awards would have been anti-dilutive.

Note 11 – Authorized shares of common and preferred stock and stock-based compensation plans

Authorized shares of common and preferred stock

Following approval by the Company’s Board of Directors and stockholders, on May 14, 2013, the Company’s certificate of incorporation was amended to increase the authorized shares of common stock by 180,000,000 shares to a total of 360,000,000 shares. As a result of this amendment, the total number of shares which the Company is authorized to issue is 365,000,000 shares, consisting of (i) 5,000,000 shares of preferred stock, par value $.01 per share, and (ii) 360,000,000 shares of common stock, par value $.01 per share.

Stock option plans  

Our stockholders approved the 1994 Incentive Stock Option Plan (the “1994 Plan”) in May 1994. At the time of approval, 13,668,750 shares of our common stock were reserved for issuance under this plan. In 1997, an additional 10,631,250 shares of our common stock were reserved for issuance under this plan, and an additional 1,125,000 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 under the options 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 of our common stock 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 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 month period ended June 30, 2014, we did not make any changes in accounting principles or methods of estimates related to the 1994 Plan.  

Restricted stock plan  

Our stockholders approved our 2005 Incentive Plan (the “2005 Plan”) in May 2005. At the time of approval, 4,050,000 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 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 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. The 2005 Plan terminated on May 11, 2010, except with respect to outstanding awards previously granted thereunder. There were 3,362,304 shares 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, 3,000,000 shares of our common stock were reserved for issuance under this plan, as well as the 3,362,304 shares 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,  five 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 3,114,411 shares available for grant under the 2010 Plan at June 30, 2014.  

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 month period ended June 30, 2014, we did not make any changes in accounting principles or methods of estimates related to the 2010 Plan.  

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 generally 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. On May 12, 2014, our stockholders approved an additional 3,000,000 shares for issuance under our employee stock purchase plan. At June 30, 2014, we had 792,683 shares of common stock reserved for future issuance under this plan. We issued 588,059 shares under this plan in the six month period ended June 30, 2014. The weighted average purchase price of the employees’ purchase rights was $23.92 per share. During the six month period ended June 30, 2014, we did not make any changes in accounting principles or methods of estimates with respect to such plan.

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 the adoption of a Preferred Stock Rights Agreement which expired on May 10, 2014. There were not any shares of preferred stock issued and outstanding at June 30, 2014.

Segment Information [Abstract]

Segment Information

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 four 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 four 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:

Derivative Instruments And Hedging Activities

Derivative Instruments And Hedging Activities [Abstract]

Derivative Instruments And Hedging Activities

Note 5 – Derivative instruments and hedging activities  

We recognize all of our derivative instruments as either assets or liabilities in our 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, we 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 50 countries. Sales outside of the Americas accounted for approximately 62% of our revenues during each of the three month periods ended June 30, 2014 and 2013,  and 61% and60% during each of the six month periods ended June 30, 2014 and 2013, 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 that are not designated as hedging instruments. 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 over the next one tothree 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 currency 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, Hungarian forint, British pound, and Malaysian ringgit) 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 loss.” Hedge effectiveness of foreign currency forwards and purchased option contracts designated 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 the following notional amounts:

(In thousands)		US Dollar Equivalent
		As of June 30, 2014		As of December 31,
		(Unaudited)		2013
Euro	$	110,755	$	75,886
Japanese yen		14,650		23,284
Hungarian forint		10,579		21,159
British pound		27,554		14,869
Malaysian ringgit		3,687		4,426
Total forward contracts notional amount	$	167,225	$	139,624

The contracts in the foregoing table had contractual maturities of 36 months or less at June 30, 2014 and December 31, 2013.  

At June 30, 2014, we expect to reclassify $182,000of gains on derivative instruments from accumulated OCI to net sales during the next twelve months when the hedged international sales occur, $165,000 of gains on derivative instruments from accumulated OCI to cost of sales when the cost of sales are incurred and $165,000 of gains on derivative instruments from accumulated OCI to operating expenses during the next twelve months when the hedged operating expenses occur. Expected amounts are based on derivative valuations at June 30, 2014. Actual results may vary as a result of changes in the corresponding exchange rates subsequent to this date.  

We did not record any ineffectiveness from our hedges during the three and six month periods ended June 30, 2014 and 2013.  

Other Derivatives  

Other derivatives not designated as hedging instruments consist primarily of foreign currency forward contracts that we use to hedge our foreign denominated net receivable or net payable positions to protect against the change in value caused by a fluctuation in foreign currency exchange rates. We typically attempt to 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 120 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, 2014 and December 31, 2013, we held foreign currency forward contracts with a notional amount of $67 million and $70 million, respectively.   

The following tables present the fair value of derivative instruments on our Consolidated Balance Sheets at June 30, 2014 and December 31, 2013, respectively.

Debt [Abstract]

Debt

Note 13 - Debt

On May 9, 2013, we entered into a Loan Agreement (the “Loan Agreement”) with Wells Fargo Bank, National Association. The Loan Agreement provides for a $50 million unsecured revolving line of credit with a scheduled maturity date of May 9, 2018 (the “Maturity Date”). Proceeds of loans made under the Loan Agreement may be used for working capital and other general corporate purposes. We may prepay the loans under the Loan Agreement in whole or in part at any time without premium or penalty. Certain of our existing and future material domestic subsidiaries are required to guaranty our obligations under the Loan Agreement. As of June 30, 2014, we had $50 million available for borrowings under this revolving line of credit.

The loans bear interest, at our option, at a base rate determined in accordance with the Loan Agreement, plus a spread of 0.0% to 0.5%, or a LIBOR rate plus a spread of 1.125% to 2.0%, in each case with such spread determined based on a ratio of consolidated indebtedness to EBITDA, determined in accordance with the Loan Agreement. Principal, together with all accrued and unpaid interest, is due and payable on the Maturity Date. We are also obligated to pay a quarterly commitment fee, payable in arrears, based on the available commitments at a rate of 0.175% to 0.300%, with such rate determined based on the ratio described above. The Loan Agreement contains customary affirmative and negative covenants. The affirmative covenants include, among other things, delivery of financial statements, compliance certificates and notices; payment of taxes and other obligations; maintenance of existence; maintenance of properties and insurance; and compliance with applicable laws and regulations. The negative covenants include, among other things, limitations on indebtedness, liens, mergers, consolidations, acquisitions and sales of assets, investments, changes in the nature of the business, affiliate transactions and certain restricted payments. The Loan Agreement also requires us to maintain a ratio of consolidated indebtedness to EBITDA equal to or less than 3.25 to 1.00, and a ratio of consolidated EBITDA to interest expense greater than or equal to 3.00 to 1.00, in each case determined in accordance with the Loan Agreement. As of June 30, 2014, we were in compliance with all covenants in the Loan Agreement.

The Loan Agreement contains customary events of default including, among other things, payment defaults, breaches of covenants or representations and warranties, cross-defaults with certain other indebtedness, bankruptcy and insolvency events, judgment defaults and change in our control, subject to grace periods in certain instances. Upon an event of default, the lender may declare all or a portion of the outstanding obligations payable by us to be immediately due and payable and exercise other rights and remedies provided for under the Loan Agreement. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default under the Loan Agreement at a per annum rate of interest equal to 2.00% above the otherwise applicable interest rate.

Income Taxes [Abstract]

Income Taxes

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.  

We account for uncertainty in income taxes recognized in our financial statements using prescribed recognition thresholds and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on our tax returns. We had $24.7 million and $23.6 million of unrecognized tax benefits at June 30, 2014 and December 31, 2013, respectively, all of which would affect our effective income tax rate if recognized. We recorded a gross increase in unrecognized tax benefits of $471,000and $976,000for the three and six month periods ended June 30, 2014, respectively, as a result of tax positions taken during these periods. Our continuing policy is to recognize interest and penalties related to income tax matters in income tax expense. As of June 30, 2014, we had approximately $1.5 million accrued for interest related to uncertain tax positions. The tax years 2007 through 2013 remain open to examination by the major taxing jurisdictions to which we are subject.  The Internal Revenue Service (“IRS”) commenced an examination of our U.S. income tax returns for 2010 and 2011 in the second quarter of 2013 and such examination was not complete as of June 30, 2014.  However, in July 2014, we agreed to the IRS findings. Although such matter is still subject to final processing by the IRS, we believe the chance of further changes to the current IRS findings for 2010 and 2011 is remote and such matter is effectively settled. Accordingly, we anticipate recognizing tax benefits of $13.9 million in the three month period ended September 30, 2014 related to 2010 and 2011 intercompany transfer pricing activity.

Our provision for income taxes reflected an effective tax rate of 23% for each of the three month periods ended June 30, 2014 and 2013, and 23% and 10% for the six month periods ended June 30, 2014 and 2013, respectively. For the three and six month periods ended June 30, 2014, our effective tax rate was lower than the U.S. federal statutory rate of 35% as a result of an enhanced deduction for certain research and development expenses, profits in foreign jurisdictions with reduced income tax rates, and a tax benefit from disqualifying dispositions of equity awards that do not ordinarily result in a tax benefit. For the three and six month periods ended June 30, 2013, our effective tax rate was lower than the U.S. federal statutory rate of 35% as a result of an enhanced deduction for certain research and development expenses, profits in foreign jurisdictions with reduced income tax rates, the research and development tax credit, and a tax benefit from disqualifying dispositions of equity awards that do not ordinarily result in a tax benefit.

Our earnings in Hungary are subject to a statutory tax rate of 19%. The difference between this rate and the statutory U.S. rate of 35% resulted in income tax benefits of $2.4 million and $1.5 million for the three month periods ended June 30, 2014 and 2013, respectively, and $4.0 million and $3.2 million for the six month periods ended June 30, 2014 and 2013, respectively. No countries other than Hungary had a significant impact on our effective tax rate. We have not entered into any advanced pricing or other agreements with the IRS with regard to any foreign jurisdictions.  

The tax position of our Hungarian operation continues to benefit from assets created by the restructuring of our operations in Hungary. In addition, our research and development activities in Hungary continue to benefit from a tax law in Hungary that provides for an enhanced deduction for qualified research and development expenses. 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 $3.2 million and $2.3 million for the three month periods ended June 30, 2014 and 2013, respectively, and $5.8 million and $4.7 million for the six month periods ended June 30, 2014 and 2013, respectively.

Earnings from our operations in Malaysia are free of tax under a tax holiday effective January 1, 2013. This tax holiday expires in 2027. If we fail to satisfy the conditions of the tax holiday, this tax benefit may be terminated early. The tax holiday resulted in an income tax benefit of $6,000 and $311,000 for the three and six month periods ended June 30, 2014, respectively.

Software development costs capitalized for the three month periods ended June 30, 2014 and 2013 were $9.6 million and $5.5 million, respectively, and related amortization expense was $3.0million and $3.5 million, respectively. For the six month periods ended June 30, 2014 and 2013, capitalized software development costs were $17.6 million and $8.5 million, respectively, and related amortization expense was $6.1 million and $7.2 million, respectively. Capitalized software development costs for the three month periods ended June 30, 2014 and 2013 included costs related to stock based compensation of $146,000 and $262,000, respectively. For the six month periods ended June 30, 2014 and 2013, capitalized software development costs included costs related to stock based compensation of $340,000 and $402,000, respectively. The related amounts in the table above are net of fully amortized assets.

Amortization 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. Acquired technology and other intangible assets are amortized over their useful lives, which range from three to eight years. Patents are amortized using the straight-line method over their estimated period of benefit, generally 10 to 17 years. Total intangible assets amortization expenses were $7.3 million and $7.9 million for the three month periods ended June 30, 2014 and 2013, respectively, and $14.9 million and $16.3 million for the six month periods ended June 30, 2014 and 2013, respectively.

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, 2014. No impairment of goodwill was identified during 2014 or 2013. Goodwill is deductible for tax purposes in certain jurisdictions.

Recently Issued Accounting Pronouncements

Note 15 – Recently issued accounting pronouncements  

In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which amends ASC 740, Income Taxes. The amendments provide guidance on the financial statement presentation of an unrecognized tax benefit, as either a reduction of a deferred tax asset or as a liability, when a net operating loss carryforward, similar tax loss, or a tax credit carryforward exists. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 and may be applied on either a prospective or retrospective basis. The provisions are effective for the Company’s Form 10-K for the year ending December 31, 2014. We do not expect the adoption of these provisions to have a significant impact on our consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The update is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for annual reporting periods, and interim periods within that period, beginning after December 15, 2016 (fiscal year 2017 for the Company) and early adoption is not permitted. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. The Company has not yet determined the potential effects of the adoption of ASU 2014-09 on its Consolidated Financial Statements.

Fair Value Measurements [Abstract]

Fair Value Measurements

Note 4 – Fair value measurements 

We define fair value to be the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market that market participants may use when pricing the asset or liability.   

We follow a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value measurement is determined based on the lowest level input that is significant to the fair value measurement. The three values of the fair value hierarchy are the following:   

Level 1 – Quoted prices in active markets for identical assets or liabilities   

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly   

Level 3 – Inputs that are not based on observable market data   

Assets and liabilities measured at fair value on a recurring basis are summarized below:

We value our available-for-sale short-term investments based on pricing from third party pricing vendors, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. We classify all of our fixed income available-for-sale securities as having Level 2 inputs. The valuation techniques used to measure the fair value of our financial instruments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques. We believe all of these sources reflect the credit risk associated with each of our available-for-sale short-term investments. Short-term investments available-for-sale consists of debt securities issued by states of the U.S. and political subdivisions of the U.S., corporate debt securities and debt securities issued by U.S. government organizations and agencies as well as debt securities issued by foreign governments. All short-term investments available-for-sale have contractual maturities of less than 40 months.  

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 similar instruments. We consider counterparty credit risk in the valuation of our derivatives. However, counterparty credit risk did not impact the valuation of our derivatives during the six month period ended June 30, 2014. There were not any transfers in or out of Level 1 or Level 2 during thesix month period ended June 30, 2014.

Our foreign government bonds consist of German government sovereign debt denominated in Euro with maximum remaining maturities of 12 months. Our short-term investments do not involve sovereign debt from any other country in Europe.

We did not have any items that were measured at fair value on a nonrecurring basis at June 30, 2014 and December 31, 2013.  

The carrying value of net accounts receivable and accounts payable contained in the Consolidated Balance Sheets approximates fair value.
