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, 2018, 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, 2019 and December 31, 2018, the results of our operations and comprehensive income for three and six months ended June 30, 2019 and 2018, the cash flows for the six months ended June 30, 2019 and 2018 and the statement of stockholder's equity for the three and six months ended June 30, 2019. Our operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States.

Recently Adopted Accounting Pronouncements

Leases

In February 2016, the Financial Accounting Standards Board ("FASB") established Topic 842, Leases, by issuing Accounting Standards Update (ASU) No. 2016-02, which supersedes ASC 840, Leases, and requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. Topic 842, as amended, (the "new lease standard") establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement.

We adopted the new lease standard on January 1, 2019 and used the effective date as our date of initial adoption. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for earlier periods.

We have completed a qualitative and quantitative assessment of our lease portfolio, in which the standard had a material impact on our consolidated balance sheet but did not have an impact on our consolidated income statement. Upon adoption, we recognized lease liabilities of approximately $52 million, with corresponding ROU assets of the same amount, based on the present value of the remaining minimum rental payments under current leasing standards for our existing operating leases. Additionally, we also reclassified approximately $19 million from "Property, plant and equipment, net" to "Operating lease right-of-use assets" related to prepaid leasehold land.

The new standard provides a number of optional practical expedients in transition. We elected the 'package of practical expedients', which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The new standard also provides practical expedients for an entity's ongoing accounting. We elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we will not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. We also elected the practical expedient to not separate lease and non-lease components for our office leases.

The cumulative effects of the changes made to our consolidated January 1, 2019 balance sheet for the adoption of the new lease standard were as follows (in thousands):



	Balance at December 31, 2018		Adjustments Due to ASU 2016-02			Balance at January 1, 2019

Assets
Property, plant and equipment, net	$	245,201	$	(18,606	)	$	226,595
Operating lease right-of-use assets	—		$	68,938		$	68,938

Liabilities and Stockholders' Equity
Operating lease liabilities, current	—		$	18,597		$	18,597
Operating lease liabilities, non-current	—		$	33,853		$	33,853
Other current liabilities	$	25,913	$	(2,118	)	$	23,795

Other Recently Adopted Accounting Pronouncements

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The ASU expands strategies that qualify for hedge accounting, changes how many hedging relationships are presented in the financial statements, and simplifies the application of hedge accounting in certain situations. On January 1, 2019, we adopted the guidance in ASU 2017-12. Adoption did not have a material impact on our financial statements. We continue to assess opportunities enabled by the new standard to expand our risk management strategies.

In August 2018, the Securities and Exchange Commission ("SEC") issued Release No. 33-10532 that amends and clarifies certain financial reporting requirements. The principal change to our financial reporting will be the inclusion of the annual disclosure requirement of changes in stockholders’ equity in Rule 3-04 of Regulation S-X to interim periods. We adopted this new rule beginning with our financial reporting for the quarter ended March 31, 2019.

In January 2018, the FASB issued ASU 2018-02, Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which gives entities the option to reclassify to retained earnings tax effects resulting from the Tax Cuts and Jobs Act (the "Act") related to items that the FASB refers to as having been stranded in accumulated other comprehensive income ("OCI"). We adopted ASU 2018-02 effective January 1, 2019, and we did not elect the option to reclassify to retained earnings the tax effects resulting from the Act that are stranded in accumulated OCI. The adoption of the new guidance did not have a material effect on our consolidated financial statements.

Recent Accounting Guidance Not Yet Adopted

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU will replace the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. We will be required to use a forward-looking expected credit loss model for accounts receivables and other financial instruments. This ASU requires instruments measured at amortized cost to be presented at the net amount expected to be collected. Entities are also required to record allowances for available-for-sale debt securities rather than reduce the carrying amount. We do not plan to adopt the ASU earlier than our required effective date of January 1, 2020. We expect that the adoption of the ASU will not have a material impact on our financial statements.

Summary of Significant Accounting Policies

As discussed above, we adopted the new lease standard as of January 1, 2019. The impact of this new guidance on our accounting policies and financial statements is described below. Additionally, in the first quarter of 2019, we granted performance-based restricted stock units to certain executives under our 2015 Equity Incentive Plan ("PRSUs"). The PRSU awards granted during the six months ended June 30, 2019 include a market condition as defined by ASC 718. The impact of the new equity awards on our accounting policies is described below. There were no other significant changes in our accounting policies during the six months ended June 30, 2019 compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2018.

Stock-Based Compensation

Stock-based compensation costs are based on the fair value on the date of grant for all restricted stock units ("RSUs") and on the date of enrollment for the employee stock purchase plan. We recognize compensation expense ratably over the requisite service period of the awards. PRSUs are RSU awards that vest based on a market condition, currently our stockholder return relative to the total stockholder return of the companies included in the Russell 2000 Index at the end of a three-year performance period. Up to 200% of the full target number of shares subject to each PRSU award are eligible to be earned after the completion of the three-year performance period based on our total stockholder return relative to the total stockholder return of the Russell 2000 Index at the end of the performance period.

The fair values of RSUs, with service-based vesting conditions, are estimated using their market price on the date of grant. The fair values of rights under employee stock purchase plans are estimated using the Black-Scholes option-pricing model. The fair values of PRSUs are estimated using a Monte Carlo simulation. The determination of fair value of the PRSUs is affected by our stock price and a number of assumptions including the expected volatility, expected dividend yield and the risk-free interest rate. Our expected volatility at the date of grant was based on the historical volatilities of our stock and the companies included in the Russell 2000 Index over the performance period.

Refer to Note 11 – Authorized shares of common and preferred stock and stock-based compensation plans for additional information on our equity-based compensation programs.

Leases

We determine whether an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets and operating lease liabilities (current and non-current) on our consolidated balance sheet. Finance leases are included in property and equipment, other current liabilities, and other long-term liabilities in our consolidated balance sheet.

Operating lease ROU assets and operating lease liabilities are recognized based on their present value of the future minimum lease payments over the lease term at commencement date. As none of our leases provide an implicit rate we use our incremental borrowing rate based on the information available as of the commencement date. The operating lease ROU assets also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

We have lease agreements with lease and non-lease components. For office leases we account for the lease and non-lease components as a single lease component. For certain leases, such as equipment and vehicles, we account for the lease and non-lease components separately. Additionally, for certain equipment leases, we apply a portfolio approach to effectively account for the operating lease ROU assets and liabilities. Refer to Note 8 - Leases for additional information on our leasing activities.

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 includes 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 months ended June 30, 2019 and 2018, are as follows:



	Three Months Ended June 30,		Six Months Ended June 30,
	(In thousands)		(In thousands)
	(Unaudited)		(Unaudited)
	2019	2018	2019	2018

Weighted average shares outstanding-diluted	132,973	133,054	133,172	132,838

Stock awards to acquire 861,000 shares and 697,800 shares for the three months ended June 30, 2019 and 2018, respectively, and 395,800 shares and 350,800 shares for the six months ended June 30, 2019 and 2018, respectively, were excluded in the computations of diluted EPS because the effect of including the stock awards would have been anti-dilutive.

Note 2 - Revenue

Revenue Recognition

Revenue is recognized upon transfer of control of the promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We enter into contracts that can include various combinations of our products or services, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of allowances for returns and any taxes collected from customers, which are subsequently remitted to governmental authorities.

The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis. Our typical performance obligations include the following:



Performance Obligation	When performance obligation is typically satisfied	When payment is typically due	How standalone selling price is typically estimated
Product revenue
Modular hardware	When customer obtains control of the product (point-in-time)	Within 30-90 days of shipment	Observable in transactions without multiple performance obligations
Software licenses	When software media is delivered to customer or made available for download electronically, and the applicable license period has begun (point-in-time)	Within 30-90 days of the beginning of license period	Perpetual/Subscription licenses: Value relationships based on (i) the directly observable pricing of the license bundled with software maintenance and (ii) the directly observable pricing of software maintenance renewals, when they are sold on a standalone basis. Enterprise-wide term licenses: Residual method
Extended hardware warranty	Ratably over the course of the support contract (over time)	Within 30-90 days of the beginning of the contract period	Observable in renewal transactions
Other related support offerings	As work is performed (over time) or course is delivered (point-in-time)	Within 30-90 days of delivery	Observable in transactions without multiple performance obligations
Software maintenance revenue
Software maintenance	Ratably over the course of the support contract (over time)	Within 30-90 days of the beginning of the contract period	Observable in renewal transactions

Disaggregation of Revenues

We disaggregate revenue from contracts with customers based on the timing of transfer of goods or services to customers (point-in-time or over time) and geographic region based on the billing location of the customer. The geographic regions that are tracked are the Americas (United States, Canada and Latin America), EMEIA (Europe, Middle East, India and Africa) and APAC (Australia, New Zealand, Southeast Asia and China). Total net sales based on the disaggregation criteria described above are as follows:

Information about Contract Balances

Amounts collected in advance of services being provided are accounted for as deferred revenue. Nearly all of our deferred revenue balance is related to extended hardware and software maintenance contracts. Payment terms and conditions vary by contract type, although payment is typically due within 30 to 90 days of contract inception. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our products and services, not to receive financing from our customers, such as invoicing at the beginning of a subscription term with a portion of the revenue recognized ratably over the contract period, or to provide customers with financing, such as multi-year on-premises licenses that are invoiced annually with revenue recognized upfront.

Changes in deferred revenue, current and long-term, during the six months ended June 30, 2019 were as follows:



	Amount
	(In thousands)
Deferred Revenue at December 31, 2018	$	159,924
Deferral of revenue billed in current period, net of recognition	100,737
Recognition of revenue deferred in prior periods	(98,745		)
Foreign currency translation impact	(192		)
Balance as of June 30, 2019 (unaudited)	$	161,724

For the six months ended June 30, 2019, revenue recognized from performance obligations satisfied in prior periods (for example, due to changes in transaction price) was not material. Amounts recognized as revenue in excess of amounts billed are recorded as unbilled receivables. Unbilled receivables which are anticipated to be invoiced in the next twelve months are included in "accounts receivable, net" on the consolidated balance sheet. Based on the nature of our contracts with customers, we do not typically recognize unbilled receivables related to revenues recognized in excess of amounts billed. For the six months ended June 30, 2019, amounts recognized related to unbilled receivables were not material.

Unsatisfied Performance Obligations

Revenue expected to be recognized in any future period related to remaining performance obligations, excluding revenue pertaining to contracts that have an original expected duration of one year or less, and excluding contracts where revenue is recognized as invoiced, was approximately $58 million as of June 30, 2019. Since we typically invoice customers at contract inception, this amount is included in our current and non-current deferred revenue balances. As of June 30, 2019, we expect to recognize approximately 25% of the revenue related to these unsatisfied performance obligations during the remainder of 2019, 40% during 2020, and 35% thereafter.

Assets Recognized from the Costs to Obtain a Contract with a Customer

We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. We have determined that certain sales incentive programs meet the requirements to be capitalized. Capitalized incremental costs related to initial contracts and renewals are amortized over the same period because the commissions paid on both the initial contract and renewals are commensurate with one another. Total capitalized costs to obtain a contract were immaterial during the periods presented and are included in other long-term assets on our consolidated balance sheets.

Practical Expedients

As discussed in Note 1 - Basis of presentation and elsewhere in Note 2 - Revenue, we have elected the following practical expedients in accordance with the new revenue standard:


•	We generally expense sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within sales and marketing expenses.


•	We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.


•	We do not consider the time value of money for contracts with original durations of one year or less.

Equity-Method Investments

The carrying value of our equity method investments was $13 million as of June 30, 2019. Our proportionate share of the income from equity-method investments was not material for the periods presented.

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. All of our short-term investments available-for-sale have contractual maturities of less than 60 months.

Derivatives include foreign currency forward 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. 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 months ended June 30, 2019. There were no transfers in or out of Level 1 or Level 2 during the six months ended June 30, 2019.

As of June 30, 2019, our short-term investments did not include sovereign debt from any country other than the United States.

We did not have any items that were measured at fair value on a nonrecurring basis at June 30, 2019 and December 31, 2018. The carrying value of net accounts receivable, accounts payable, and long-term debt 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 approximately 50 countries. Sales outside of the Americas accounted for approximately 61% and 62% of our net sales during the three months ended June 30, 2019 and 2018, and approximately 61% and 62% of our net sales during the six months ended June 30, 2019 and 2018, 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 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, in that 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 contracts as hedges of forecasted sales that are denominated in foreign currencies and as hedges of foreign currency denominated financial assets or liabilities. 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 sales expenses will be adversely affected by changes in exchange rates.

We designate foreign currency forward contracts as cash flow hedges of forecasted net sales 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 to three years, we have instituted a foreign currency cash flow hedging program. We hedge portions of our forecasted net sales and forecasted expenses denominated in foreign currencies with 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. We purchase foreign currency forward contracts for up to 100% of our forecasted exposures in selected currencies (primarily in Euro, Japanese yen, Hungarian forint, British pound, Malaysian ringgit, Korean won and Chinese yuan) and limit the duration of these contracts to 36 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 OCI and reclassified into earnings in the same line item (net sales, operating expenses, or cost of sales) associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings or expenses during the current period and are classified as a component of “net foreign exchange gain (loss).” Hedge effectiveness of foreign currency forwards 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 designated as cash flow hedges with the following notional amounts:



(In thousands)	US Dollar Equivalent
	As of June 30, 2019		As of December 31,
	(Unaudited)		2018
Chinese yuan	$	66,023	$	45,520
Euro	130,740		134,654
Japanese yen	34,598		15,141
Hungarian forint	43,200		35,384
British pound	18,890		9,948
Malaysian ringgit	27,975		27,778
Korean won	11,452		8,331
Total forward contracts notional amount	$	332,878	$	276,756

The contracts in the foregoing table had contractual maturities of 18 months or less and 24 months or less at June 30, 2019 and December 31, 2018, respectively.

At June 30, 2019, we expect to reclassify $6.5 million of gains on derivative instruments from accumulated OCI to net sales during the next twelve months when the hedged international sales occur, $0.2 million of losses on derivative instruments from accumulated OCI to cost of sales during the next twelve months when the cost of sales are incurred and $0.1 million of losses 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, 2019. Actual results may vary materially as a result of changes in the corresponding exchange rates subsequent to this date.

The gains and losses recognized in earnings due to hedge ineffectiveness were not material for each of the six months ended June 30, 2019 and 2018 and are included as a component of net income under the line item “net foreign exchange loss.”

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 help 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 90 days or less. 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 loss.” As of June 30, 2019 and December 31, 2018, we held foreign currency forward contracts that were not designated as hedging instruments with a notional amount of $47 million and $71 million, respectively.

The following tables present the fair value of derivative instruments on our Consolidated Balance Sheets at June 30, 2019 and December 31, 2018, respectively.

Software development costs capitalized for the three months ended June 30, 2019 and 2018 were $2.2 million and $3.9 million, respectively, and related amortization expense was $6.9 million and $6.8 million, respectively. For the six months ended June 30, 2019 and 2018, capitalized software development costs were $4.6 million and $11.9 million, respectively, and related amortization expense was $13.8 million and $12.9 million, respectively. Capitalized software development costs for the three months ended June 30, 2019 and 2018 included costs related to stock-based compensation of $0.0 million and $0.2 million, respectively. For the six months ended June 30, 2019 and 2018, capitalized software development costs included costs related to stock-based compensation of $0.1 million and $0.5 million, 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 to six 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 $9.1 million and $9 million for the three months ended June 30, 2019 and 2018, respectively, and $18.1 million and $17.4 million for the six months ended June 30, 2019 and 2018, respectively.

Goodwill

The carrying amount of goodwill as of June 30, 2019, was as follows:



	Amount
	(In thousands)
Balance as of December 31, 2018	$	264,530
Foreign currency translation impact	(546		)
Balance as of June 30, 2019 (unaudited)	$	263,984

The excess purchase price over the fair value of assets acquired is recorded as goodwill. As we have one operating segment comprised of components with similar economic characteristics, 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 is performed in the fourth quarter of each year.

No impairment of goodwill was identified during the six months ended June 30, 2019 or the twelve months ended December 31, 2018.

Note 8 – Leases

We have operating leases for corporate offices, automobiles, and certain equipment. Our leases have remaining terms of 1 year to 95 years, some of which may include options to extend the leases for up to 9 years, and some of which may include options to terminate the leases within 1 year. Leases with an initial term of 12 months or less are not recorded on the balance sheet. We recognize lease expense for these leases on a straight-line basis over the lease term.

Amounts related to finance lease activities and income from leasing activities were not material for the periods presented.

As of June 30, 2019, we have additional operating leases, that have not commenced during the period, which were not material.

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 had a valuation allowance of $80 million at June 30, 2019 and December 31, 2018. A majority of the valuation allowance is related to the deferred tax assets of National Instruments Hungary Kft. (“NI Hungary”).

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 $8.3 million and $9.8 million of unrecognized tax benefits at June 30, 2019 and December 31, 2018, respectively, all of which would affect our effective income tax rate if recognized. We recorded a gross increase in unrecognized tax benefits of $0.2 million and $0.4 million for the three and six months ended June 30, 2019, respectively, as a result of the tax positions taken during these and prior periods. We recorded a gross decrease in unrecognized tax benefits of $2.0 million for each of the three and six months ended June 30, 2019, as a result of closing open tax years. As of June 30, 2019, it is reasonably possible that we will recognize tax benefits in the amount of $1.5 million in the next twelve months due to the closing of open tax years. The nature of the uncertainty is related to deductions taken on returns that have not been examined by the applicable tax authority. Our continuing policy is to recognize interest and penalties related to income tax matters in income tax expense. As of June 30, 2019, we had approximately $0.8 million accrued for interest related to uncertain tax positions. The tax years 2012 through 2019 remain open to examination by the major taxing jurisdictions to which we are subject.

Our provision for income taxes reflected an effective tax rate of 13% and 11% for the three months ended June 30, 2019 and 2018, respectively, and 12% and 14% for the six months ended June 30, 2019 and 2018, respectively. For the three and six months ended June 30, 2019, our effective tax rate was lower than the U.S. federal statutory rate of 21% as a result of an enhanced deduction for certain research and development expenses, profits in foreign jurisdictions with reduced income tax rates, the deduction for foreign-derived deduction eligible income, a decrease in unrecognized tax benefits resulting from the closing of open tax years, the research and development tax credit, excess tax benefits from share-based compensation, and a tax benefit from disqualifying dispositions of equity awards that do not ordinarily result in a tax benefit, offset by the U.S. tax on global intangible low-taxed income and nondeductible officer compensation. For the three and six months ended June 30, 2018, our effective tax rate was lower than the U.S. federal statutory rate of 21% as a result of an enhanced deduction for certain research and development expenses, profits in foreign jurisdictions with reduced income tax rates, the deduction for foreign-derived deduction eligible income, the research and development tax credit, excess tax benefits from share-based compensation, and a tax benefit from disqualifying dispositions of equity awards that do not ordinarily result in a tax benefit, offset by the U.S. tax on global intangible low-taxed income.

Our earnings in Hungary are subject to a statutory tax rate of 9%. In addition, our research and development activities in Hungary benefit from a tax law in Hungary that provides for an enhanced deduction for qualified research and development expenses. The tax position of our Hungarian operations resulted in income tax benefits of $1.6 million and $2.9 million for the three months ended June 30, 2019 and 2018, respectively, and $2.6 million and $4.6 million for the six months ended June 30, 2019 and 2018, 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 income tax benefits of the tax holiday for the three and six months ended June 30, 2019 were approximately $0.8 million and $1.3 million, respectively. The income tax benefits of the tax holiday for the three and six months ended June 30, 2018 were approximately $0.5 million and $1.1 million, respectively. The impact of the tax holiday on a per share basis for each of the three and six months ended June 30, 2019 and June 30, 2018 was a benefit of $0.01 per share.

No other taxing jurisdictions 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.

Note 10 – Comprehensive income

Our comprehensive income is comprised of net income, foreign currency translation, unrealized gains and losses on forward contracts and securities classified as available-for-sale. The accumulated OCI, net of tax, for the six months ended June 30, 2019 and 2018, consisted of the following:

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 $0.01 per share, and (ii) 360,000,000 shares of common stock, par value $0.01 per share.

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 our 1994 Incentive Plan which terminated in May 2005 (the “1994 Plan”), 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 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 the 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. The 2010 Plan terminated on May 12, 2015, except with respect to the outstanding awards previously granted thereunder. There were 2,518,416 shares of common stock that were reserved but not issued under the 2010 Plan as of May 12, 2015.

Our stockholders approved our 2015 Equity Incentive Plan (the “2015 Plan”) on May 12, 2015. At the time of approval, 3,000,000 shares of our common stock were reserved for issuance under this plan, as well as the 2,518,416 shares of common stock that were reserved but not issued under the 2010 Plan as of May 12, 2015, and any shares that were returned to the 1994, 2005, and the 2010 Plans as a result of the forfeiture or termination of options or RSUs or repurchase of shares issued under these plans. The 2015 Plan, administered by the Compensation Committee of the Board of Directors, provides for the 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 and such awards may be subject to performance-based vesting conditions. Awards vest over a three, four, 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 1,933,363 shares available for grant under the 2015 Plan at June 30, 2019.

During the six months ended June 30, 2019, we granted PRSUs to certain executives under our 2015 Plan. Refer to the "Summary of Significant Accounting Policies" in Note 1 - Basis of presentation for additional discussion regarding the impact of these grants on our accounting policies and related estimates.

Employee stock purchase plan

Our employee stock purchase plan permits substantially all domestic employees and employees of designated subsidiaries to acquire our common stock at a purchase price of 85% of the lower of the market price at the beginning or the end of the purchase period. The plan has quarterly purchase periods 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 9, 2017, our stockholders approved an additional 3,000,000 shares for issuance under our employee stock purchase plan. At June 30, 2019, we had 1,525,607 shares of common stock reserved for future issuance under this plan. We issued 469,437 shares under this plan in the six months ended June 30, 2019 and the weighted average purchase price was $37.59 per share. During the six months ended June 30, 2019, 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 no shares of preferred stock issued and outstanding at June 30, 2019.

Stock repurchases and retirements

From time to time, our Board of Directors has authorized various programs for our repurchase of shares of our common stock depending on market conditions and other factors. Under the current program, during the three months ended June 30, 2019, we repurchased 1,114,500 shares of our common stock at a weighted average price per share at $41.25 and during the six months ended June 30, 2019, we repurchased 2,149,598 shares of our common stock at a weighted average price per share of $42.97. We did not repurchase any shares during the six months ended June 30, 2018. At June 30, 2019, there were 1,850,402 shares remaining available for repurchase under this program. This repurchase program does not have an expiration date.

Note 12 – Segment and geographic information

We operate as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker, who is our chief executive officer, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker evaluates our financial information and resources and assesses the performance of these resources on a consolidated basis. Since we operate in one operating segment, all required financial segment information can be found in the condensed consolidated financial statements and the notes thereto.

We sell our products in three geographic regions which consist of Americas, EMEIA and APAC. Our sales to these regions share similar economic characteristics, similar product mix, similar customers, and similar distribution methods. Revenue from the sale of our products, which are similar in nature, and software maintenance is reflected as total net sales in our Consolidated

Statements of Income. (See Note 2 -Revenue of Notes to Consolidated Financial Statements for total net sales by the major geographic areas in which we operate).

Based on the billing location of the customer, total sales outside the U.S. for the three months ended June 30, 2019 and 2018 were $211 million and $222 million, respectively, and $409 million and $422 million for the six months ended June 30, 2019 and 2018, respectively. Total property and equipment, net, outside the U.S. was $119 million as of June 30, 2019 and $132 million at December 31, 2018, respectively. Revenues and long-lived assets attributable to each individual foreign country outside the U.S. were not material.

Note 13 - Debt

On May 9, 2013, we entered into a Loan Agreement (the “Loan Agreement”) with Wells Fargo Bank (the “Lender”). The Loan Agreement provided for a $50 million unsecured revolving line of credit with a scheduled maturity date of May 9, 2018 (the “Maturity Date”). On October 29, 2015, we entered into a First Amendment to Loan Agreement (the “Amendment”) with the Lender, which amended our Loan Agreement to among other things, (i) increase the unsecured revolving line of credit from $50 million to $125 million, (ii) extend the Maturity Date of the line of credit from May 9, 2018 to October 29, 2020, and (iii) provide us with an option to request increases to the line of credit of up to an additional $25 million in the aggregate, subject to consent of the Lender and terms and conditions to be mutually agreed between us and the Lender. On April 27, 2018, we entered into a Second Amendment to Loan Agreement (the "Second Amendment") which amended the Loan Agreement, as amended by the Amendment to, among other things, (i) reduce the revolving line of credit from $125.0 million to $5.0 million, (ii) reduce the letter of credit sublimit under the line of credit from $10.0 million to $5.0 million and (iii) require us and our subsidiaries to comply with certain of the affirmative and negative covenants under the Loan Agreement only if loans are outstanding under the Loan Agreement or if we have not reimbursed any drawing under a letter of credit issued under the Loan Agreement within five business days following the request of the Lender.

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 0.50%, or a LIBOR rate plus a spread of 1.13% to 2.00%, 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 0.18% to 0.30%, 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, 2019, we were in compliance with all applicable 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 control events, 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. 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, 2019, we had no outstanding borrowings under this line of credit. During the three and six months ended June 30, 2019 and June 30, 2018, we incurred no interest expense. As of June 30, 2019 and June 30, 2018, the weighted-average interest rate on the revolving line of credit was 3.4% and 3.2%, respectively.

Note 14 – Commitments and contingencies

We offer a one-year limited warranty on most hardware products which is included in the terms of sale of such products. We also offer optional extended warranties on our hardware products for which the related revenue is recognized ratably over the warranty period. Provision is made for estimated future warranty costs at the time of the sale for the estimated costs that may be incurred under the standard warranty. Our estimate is based on historical experience and product sales during the period. The warranty reserve for the six months ended June 30, 2019 and 2018 was as follows:



	Six Months Ended June 30,

As of June 30, 2019, we had non-cancelable purchase commitments with various suppliers of customized inventory and inventory components totaling approximately $6.9 million over the next twelve months.

Note 15 – Restructuring

Since the first quarter of 2017, we have been taking steps to reduce our overall employee headcount in an effort to minimize job duplication or evaluate where we should shift and centralize activities, improve efficiencies, and rebalance our resources on higher return activities. The timing and scope of our headcount reductions will vary.

Note 16 – Litigation

We are not currently a party to any material litigation. However, in the ordinary course of our business, we have in the past, are currently and will likely become involved in various legal proceedings, claims, and regulatory, tax or government inquiries and investigations, 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 investigation, litigation or dispute.

Note 17 – Subsequent events

On July 24, 2019, our Board of Directors declared a quarterly cash dividend of $0.25 per common share, payable on September 3, 2019, to stockholders of record on August 12, 2019.

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, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Overview

For more than 40 years, National Instruments Corporation (the “Company”, “we”, “us” or “our”) has enabled engineers and scientists around the world to accelerate productivity, innovation and discovery. Our software-centric platform provides an advanced approach through integration of software and modular hardware to create automated test and automated measurement systems. We believe our long-term track record of innovation and our differentiated platform help support the success of our customers, employees, suppliers and stockholders. We have been profitable in every year since 1990. We sell to a large number of customers in a wide variety of industries.

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 that it is crucial that we continue to offer products with high 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 open architectures on multiple platforms and leveraging our core technologies across multiple products.

We sell automated test and automated measurement systems in a broad range of industries and are subject to the economic and industry forces that 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 advanced research, automotive, automated test equipment, commercial aerospace, computers and electronics, consumer electronics, continuous process manufacturing, education, government/defense, medical research/pharmaceutical, power/energy, semiconductors, and telecommunications.

Leveraging a worldwide sales, distribution and manufacturing network

We distribute and sell our software and hardware products primarily through a direct sales organization. We also use independent distributors, original equipment manufacturers, value-added resellers, system integrators, and consultants to market and sell 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 61% and 62% of our net sales during the three months ended June 30, 2019 and 2018, respectively, and approximately 61% and 62% of our net sales during the six months ended June 30, 2019 and 2018, 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 net sales will continue to be derived from international sales. (See Note 2 - Revenue of Notes to Consolidated Financial Statements for details concerning the geographic breakdown of our net sales).

We manufacture substantially all of our product volume at our facilities in Debrecen, Hungary and Penang, Malaysia. 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 our electronic circuit card assemblies, modules and chassis are manufactured in house, although contractors are used from time to time. The majority of our electronic cable assemblies are produced by contractors; however, we do manufacture some on an exception basis. Our software duplication, technical manuals and product support documentation are primarily produced by contractors.

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 depends 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 not decline, 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. Historically, our business cycles have generally followed the expansion and contraction cycles in the global industrial economy as measured by the Global PMI. For the three months ended June 30, 2019, the average of the Global PMI was 49.9 and the average of the new order element of the Global PMI was 49.5. A Global PMI of 50.0 is a neutral rating, a number greater than 50.0 is indicative of expansion and a number less than 50.0 is indicative of contraction.

In the past, we have seen deterioration in the industrial economy translate to a negative impact on our net sales. Additionally, we continue to face unexpected headwinds related to increased trade restrictions impacting sales to certain third parties and softening demand for some of our broad-based product offerings and certain applications within the transportation market. These factors could contribute to an adverse effect on the spending patterns of businesses, including our current and potential customers, which could negatively impact our revenues and results of operations. Although we remain cautious about economic uncertainty indicated by these headwinds along with the continued weakening of the PMI, particularly in the Eurozone, we are encouraged by our continuing commitment to disciplined execution of our long-term goals. Additionally, we remain optimistic about our strategic objectives for the company and our long-term position in the industry through the sustained differentiation we deliver to our customers through our platform-based approach.

Since the first quarter of 2017, we have been taking steps to optimize our processes, reduce job duplication, evaluate where we should shift and centralize activities, improve efficiencies, and rebalance our resources on higher return activities. We incurred $3 million in severance and other restructuring-related charges, net of tax during the three months ended June 30, 2019. The timing and scope of any future headcount reductions will vary.

During the three and six months ended June 30, 2019, we saw continued volatility in the exchange rates between the U.S. dollar and many of the currency markets where we have exposure. This volatility had a material negative impact on our net sales and results of operations for the three and six months ended June 30, 2019. As of the date of this filing, the U.S. dollar index, as tracked by the St. Louis Federal Reserve, remains near its ten-year high. See “Results of Operations” below for additional discussion on the impact of foreign exchange rates on our business for the three and six months ended June 30, 2019. See “Our Revenues are Subject to Seasonal Variations” under “Risk Factors” for additional discussion of potential fluctuations in our net sales.

We have hedging programs in place to help mitigate the risks associated with foreign currency exchange rate fluctuations. However, there can be no assurance the hedges will offset more than a portion of the financial impact resulting from movements in the foreign currency markets in which we do business. (See Note 5 – Derivative instruments and hedging activities of Notes to Consolidated Financial Statements for additional details concerning our hedging programs.)

Results of Operations for the three and six months ended June 30, 2019 and 2018

Net Sales. The following table sets forth our net sales for the three and six months ended June 30, 2019 and 2018 along with the changes between the corresponding periods.



	Three Months Ended June 30,						Six Months Ended June 30,

Figures may not sum due to rounding.

Orders with a value greater than $20,000 decreased by 2% year over year during the three months ended June 30, 2019, compared to the year over year increase of 16% in the three months ended June 30, 2018. During the six months ended June 30, 2019, orders with a value greater than $20,000 increased by 1% year over year compared to the year over year increase of 11% in the six months ended June 30, 2018.

The slight decrease in our net sales was primarily related to the impact of changes in foreign currency exchange rates and softening demand for some of our broad-based product offerings and certain applications within the transportation market. Additionally, although orders with a value greater than $20,000 were relatively flat during the first six months of 2019, we continued to experience increased adoption of our semiconductor development and test applications.

During the three months ended June 30, 2019 and 2018, orders over $20,000 were 59% and 58% of our total orders, respectively, and for the six months ended June 30, 2019 and 2018, these orders were 59% and 57% of our total orders, respectively. Orders with a value greater than $20,000, particularly those orders with a value greater than $100,000, are more volatile, are subject to greater discount variability, and may contract at a faster pace during an economic downturn compared to our other orders.

The following table sets forth our net sales by geographic region for the three and six months ended June 30, 2019 and 2018 along with the changes between the corresponding periods and the region’s percentage of total net sales.

We expect sales outside of the Americas to continue to represent a significant portion of our net sales. 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.), EMEIA, and APAC are denominated in local currencies, and accordingly, the U.S. dollar equivalent of these sales is affected by changes in foreign currency exchange rates. In order to provide a framework for assessing how our underlying business performed excluding the effects of foreign currency fluctuations between periods, we compare the percentage change in our results from period to period using constant currency disclosure. To calculate the change in constant currency, current and comparative prior period results for entities reporting in currencies other than U.S. Dollars are converted into U.S. Dollars at constant exchange rates (i.e., the average rates in effect during the three and six months ended June 30, 2018). The following tables present this information, along with the impact of changes in foreign currency exchange rates on sales denominated in local currencies, for the three and six months ended June 30, 2019.

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 maintain a foreign currency cash flow hedging program. We hedge portions of our forecasted net sales denominated in foreign currencies with average rate forward contracts. During the three months ended June 30, 2019 and 2018, these hedges had the effect of increasing our net sales by $2.7 million and decreasing our net sales by $1.3 million, respectively. During the six months ended June 30, 2019 and 2018, these hedges had the effect of increasing our net sales by $4.4 million and decreasing our net sales by $3.9 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 impact on our net sales for 2019 and 2018).

Gross Profit. Our gross profit as a percentage of sales is impacted by many factors including changes in the amount of revenues from our large customers and changes in the foreign currency exchange markets. We continue to focus on cost control and cost reduction measures throughout our manufacturing cycle. The following table sets forth our gross profit and gross profit as a percentage of net sales for the three and six months ended June 30, 2019 and 2018 along with the percentage changes in gross profit for the corresponding periods.



	Three Months Ended June 30,		Six Months Ended June 30,
	(Unaudited)		(Unaudited)

(In millions)	2019	2018	2019	2018

Gross Profit	$250.5	$258.9	$485.5	$496.2
% change compared with prior period	(3.2)%		(2.2)%
Gross Profit as a percentage of net sales	74.9%	75.9%	75.2%	76.0%

The decreases in our gross profit and gross profit as a percentage of net sales for the three and six months ended June 30, 2019, compared to the same periods in 2018 are primarily attributable to changes in foreign currency exchange rates. For the three months ended June 30, 2019 and 2018, the change in exchange rates had the effect of decreasing our cost of sales by $1.6 million and increasing our cost of sales by $2.0 million, respectively. For the six months ended June 30, 2019 and 2018, the change in exchange rates had the effect of decreasing our cost of sales by $2.9 million and increasing our cost of sales by $3.9 million, 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 months ended June 30, 2019 and 2018, these hedges had the effect of increasing our cost of sales by $0.1 million and decreasing our cost of sales by $0.3 million, respectively. During the six months ended June 30, 2019 and 2018, these hedges had the effect of increasing our cost of sales by $0.0 million and decreasing our cost of sales by $0.6 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 impact on our cost of sales for 2019 and 2018).

We do not typically maintain a large amount of order backlog as orders typically translate to sales quickly. As such, any weakness in orders typically has a pronounced impact on our net sales in the short term.

Operating Expenses. The following table sets forth our operating expenses for the three and six months ended June 30, 2019 and 2018 along with the percentage changes between the corresponding periods and the line item as a percentage of total net sales.



	Three Months Ended June 30,					Six Months Ended June 30,

Percentage of total net sales	65%		65%			67%		66%

The year over year decrease in our operating expenses during the three months ended June 30, 2019 was primarily related to the following:

•$5 million decrease related to the year over year impact of changes in foreign currency exchange rates;

•$4 million increase due to additional stock-based compensation expense, primarily attributable to comparatively

higher share prices on the grant date of unvested RSU awards;

•$3 million decrease in marketing and outside service costs;

•$1 million increase in our research and development expenses, primarily attributable to a decrease in our software

development costs eligible for capitalization, as described in more detail below.

The year over year decrease in our operating expenses during the six months ended June 30, 2019 was primarily related to the following:

•$9 million decrease related to the year over year impact of changes in foreign currency exchange rates;

•$7 million increase due to additional stock-based compensation expense, primarily attributable to

comparatively higher share prices on the grant date of unvested RSU awards;

•$6 million increase in our research and development expenses, primarily attributable to a decrease in our

software development costs eligible for capitalization, as described in more detail below;

•$4 million decrease in personnel costs, primarily attributable to a decrease in variable compensation costs;

•$1 million decrease in marketing and outside service costs.

In the three months ended June 30, 2019, we capitalized $2.2 million of software development costs compared to $3.9 million in the three months ended June 30, 2018. In the second quarter of 2018, we began moving toward more frequent releases for many of our software products. Specifically, for many of our software development projects we started applying agile development methodologies which are characterized by a more dynamic development process with more frequent and iterative revisions to a product release's features and functions as the software is being developed. Due to the shorter development cycle and focus on rapid production associated with agile development, we expect that for a significant majority of our software development projects the costs incurred subsequent to the achievement of technological feasibility will be immaterial in future periods and we expect to record significantly less capitalized software development costs than under our historical software development approaches. Consequently, a larger portion of our software development expenditures have been recognized as operating expenses starting in the second quarter of 2018. We also expect amortization of previously capitalized software development costs will begin to steadily decline as previously capitalized software development costs become fully amortized over the next four years.

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 that those resources are concentrated in areas and on initiatives that will contribute to future growth in our business.

Operating Income. For the three months ended June 30, 2019 and 2018, operating income was $32 million and $37 million, respectively, a decrease of 13%. As a percentage of net sales, operating income was 9.7% and 10.8% for the three months ended June 30, 2019 and 2018, respectively. For the six months ended June 30, 2019 and 2018, operating income was $56 million and $65 million, respectively, a decrease of 14%. As a percentage of net sales, operating income was 8.6% and 10.0% for the six months ended June 30, 2019 and 2018, respectively. The decreases in operating income in absolute dollars for the three months ended June 30, 2019, compared to the three months ended June 30, 2018, and for the six months ended June 30, 2019, compared to the six months ended June 30, 2018, are attributable to the factors discussed in Net Sales, Gross Profit and Operating Expenses above.

Interest Income. For the three months ended June 30, 2019 and 2018, interest income was $2.0 million and $1.3 million, respectively. For the six months ended June 30, 2019 and 2018, interest income was $4.3 million and $2.3 million, respectively. Recently we have seen moderate declines to the yields for high quality investment alternatives that comply with our corporate investment policy which could negatively impact the amount of interest income from our investment portfolio for the remainder of 2019.

Net Foreign Exchange Loss. For the three months ended June 30, 2019 and 2018, net foreign exchange loss was $(1.6) million and $(2.1) million, respectively. During the six months ended June 30, 2019 and 2018, net foreign exchange loss was $(1.2) million and $(1.1) 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 first half of 2019, we saw continued volatility in the exchange rates between the U.S. dollar and many of the currency markets where we have exposure. In the past, we have noted that volatility in the foreign currency exchange 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 net sales and expenses and on the effectiveness of our hedging programs. We cannot predict to what degree foreign currency markets will fluctuate in the future. In the past, these dynamics have also adversely affected our net sales 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. See “Results of Operations - Net Sales” above for additional discussion on the impact of foreign exchange rates on our net sales of operations for the three and six months ended June 30, 2019.

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 loss.” Our hedging strategy increased our foreign exchange loss by $(0.1) million and decreased our foreign exchange loss by $1.6 million in the three months ended June 30, 2019 and June 30, 2018, respectively. Our hedging strategy increased our foreign exchange loss by $(0.4) million and increased our foreign exchange loss by $(0.2) million in the six months ended June 30, 2019 and 2018, respectively. (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).

Provision for Income Taxes. For the three months ended June 30, 2019 and 2018, our provision for income taxes reflected an effective tax rate of 13% and 11%, respectively. For the six months ended June 30, 2019 and 2018, our provision for income taxes reflected an effective tax rate of 12% and 14%, 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, 2019		June 30, 2019
	(Unaudited)		(Unaudited)
Effective tax rate at June 30, 2018	11	%	14	%

Liquidity and Capital Resources

Overview

At June 30, 2019, we had $440 million in cash, cash equivalents and short-term investments. 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, all of our short-term investments that are located outside of the U.S. are denominated in the U.S. dollar with the exception of $5 million U.S. dollar equivalent of corporate bonds that are denominated in Euro. The following table presents the geographic distribution of our cash, cash equivalents, and short-term investments as of June 30, 2019 (in millions):



	Domestic	International	Total
Cash and cash equivalents	$42.9	$148.9	$191.8
	22%	78%
Short-term investments	$198.7	$49.2	$247.9
	80%	20%
Total cash, cash equivalents and short-term investments	$241.6	$198.1	$439.7
	55%	45%

The following table presents our working capital, cash and cash equivalents and short-term investments:



	June 30, 2019		December 31,		Increase/

Total cash, cash equivalents and short-term investments	$	439,653	$	530,782	$	(91,129	)

(1) Included in working capital

Our principal sources of liquidity include cash, cash equivalents, and marketable securities, as well as the cash flows generated from our operations.

The primary driver of the net decrease in working capital between December 31, 2018 and June 30, 2019 was the $91 million decrease in total cash, cash equivalents, and short-term investments. Additionally, other changes in working capital were related to:


◦	"Accounts receivable, net" decreased by $20 million. Days sales outstanding (“DSO”) was relatively flat at 65 days at June 30, 2019, and December 31, 2018. The decrease in accounts receivable is primarily related to seasonal variations in our quarterly net sales.


◦	Inventory increased by $13 million to $207 million at June 30, 2019, from $194 million at December 31, 2018. Inventory turns were 1.6 and 1.8 at June 30, 2019 and December 31, 2018, respectively. The increase in inventory was primarily attributable to an increase in raw materials due to increased lead times and higher global demand for certain electronic components.


◦	Prepaid expenses and other current assets increased by $12 million which was primarily related to an increase in prepaid freight costs in addition to the timing of insurance and maintenance renewals.


◦	Accrued compensation decreased by $6 million which can be attributed to a decrease in payments expected under our company profit sharing and bonus plans.


◦	Accounts payable increased by $7 million, primarily due to the timing of payments for services.


◦	Accrued expenses and other liabilities decreased by $13 million due to the timing and amount of tax related payments.


◦	Operating lease liabilities, current. increased by $16 million which was entirely related to the adoption of the new leasing standard on January 1, 2019, as discussed in Note 1 - Basis of presentation and Note 8 - Leases.

◦Other taxes payable decreased by $2 million related to the timing of payments for VAT and other indirect taxes.

Analysis of Cash Flow

The following table summarizes our cash flow results for the six months ended June 30, 2019 and 2018.




	Six Months Ended June 30,
(In thousands)	(unaudited)
	2019			2018
Cash provided by operating activities	$	88,637		$	98,852
Cash used in investing activities	(15,485		)	(124,685		)
Cash used in financing activities	(140,797		)	(43,953		)
Effect of exchange rate changes on cash	20			(2,759		)
Net change in cash and cash equivalents	(67,625		)	(72,545		)
Cash and cash equivalents at beginning of year	259,386			290,164
Cash and cash equivalents at end of period	$	191,761		$	217,619

Operating Activities Cash provided by operating activities for the six months ended June 30, 2019 decreased by $10 million compared to the same period in 2018. This decrease was primarily due to a $15 million decrease in operating assets and liabilities, which was partially offset due to a $7 million increase in stock-based compensation.

Investing Activities Cash used for investing activities for the six months ended June 30, 2019 decreased by $109 million compared to the same period in 2018. This was primarily attributable to a net sale of short-term investments of $25 million compared to a net purchase of short-term investments of $90 million during the same period in 2018. Investing cash outflows related to capitalized software development decreased by $7 million compared to the same period in 2018 due to a decrease in development costs eligible for capitalization related to a recent shift for several of our software projects to a more iterative software development cycle. Due to this change in how we develop these software products, we expect the portion of software development expenditures that will be recognized as research and development expenses when incurred, and consequently, classified as operating cash flows, to increase in future periods.

Financing Activities Cash used by financing activities increased by $97 million for the six months ended June 30, 2019 compared to the same period in 2018. This was primarily related to an increase of $92 million in cash outflows used to repurchase 2,149,598 shares of our common stock and a $5 million increase in cash outflows related to the increase in our quarterly dividend offset by a $1 million increase in proceeds from issuance of our common stock under our employee stock purchase plan.

Contractual Cash Obligations. Information related to our contractual obligations as of December 31, 2018 can be found in “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Contractual Obligations,” in Part II-Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 filed with the SEC on February 21, 2019 (the “2018 Form 10-K”). At June 30, 2019, there were no material changes outside the ordinary course of business to our contractual obligations from those reported in our 2018 Form 10-K. See Note 8 - Leases for additional information regarding our non-cancellable operating lease obligations as of June 30, 2019.

Loan Agreement. As amended through April 27, 2018, the Loan Agreement provides for (i) a revolving line of credit of $5.0 million, (ii) a letter of credit sublimit under the line of credit of $5.0 million, and (iii) requires us and our subsidiaries to comply with certain of the affirmative and negative covenants under the Loan Agreement only if loans are outstanding under the Loan Agreement or if we have not reimbursed any drawing under a letter of credit issued under the Loan Agreement within five business days following the request of the Lender. 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. (See Note 13 – Debt of Notes to Consolidated Financial Statements for additional details on our revolving line of credit).

Off-Balance Sheet Arrangements. We do not have any off-balance sheet debt. At June 30, 2019, 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, 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. On June 25, 2019, we entered into an agreement to sell our 136,000 square foot office building and property located in Austin, TX. The expected proceeds from the sale are $33.6 million. The transaction is expected to close in the third quarter of 2019. Additionally, the enactment of the Tax Cuts and Jobs Act allows us to repatriate our foreign cash for domestic needs without additional taxation. We may also seek to pursue additional financing or to raise additional funds by seeking an increase in our unsecured revolving line of credit under our Loan Agreement or selling equity or debt to the public or in private transactions from time to time. If we elect to raise additional funds, we may not be able to obtain such funds on a timely basis or 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.

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;


•	repurchases of our common stock;


•	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;


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


•	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;


•	capital improvements for facilities;


•	our relationships with suppliers and customers; and


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

Recently Issued Accounting Pronouncements

See Note 1 – Basis of presentation in Notes to Consolidated Financial Statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Changes in currency exchange rates and interest rates are our primary financial market risks. Quantitative and qualitative disclosures about market risk appear in “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” in Part II of our 2018 Form 10-K and there were no material changes during the six months ended June 30, 2019 to this information reported in our 2018 Form 10-K.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Based on an evaluation under the supervision and with the participation of our management, our principal executive officer and our principal financial officer have concluded that our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act were effective as of June 30, 2019, to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and (ii) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

Effective January 1, 2019, we adopted ASU 2016-02, Leases and all of the related amendments. Although the new lease standard is not expected to have a material impact on our operating results on an ongoing basis, we did implement changes to our processes related to lease control activities, including information systems. These included the development of new policies based on identifying leases, determining lease commencement, calculating the present value of leases, determining the incremental borrowing rate and gathering information for required disclosures. There were no other changes in our internal control over financial reporting during the second quarter of 2019, which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this Form 10-Q, you should carefully consider the risk factors discussed below. The risks described below are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, or operating results.

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. Uncertainty about global and regional economic conditions poses a risk to us as businesses may decrease or postpone spending in response to events such as the impending Brexit, continued trade tensions and restrictions between the U.S. and other parts of the world, financial market volatility, tariffs or other trade restrictions, government austerity programs, government regulatory actions, negative financial news, geopolitical instability, declines in income or asset values, or other factors. Negative trends or sentiments in worldwide and regional economic conditions have in the past and could again have a material adverse effect on demand for our products and services. Even if resolved, this could have a broad negative impact on the global industrial economy, which could have a material adverse impact on our business and our results of operations. These factors as well as others we may not contemplate could have a material adverse effect on the spending patterns of businesses including our current and potential customers which could have a material adverse effect on our net sales and our results of operations. See “Current business outlook” in this Form 10-Q for information regarding recent business conditions.

We are Subject to Various Risks Associated with International Operations and Foreign Economies. Our international sales are subject to inherent risks, including, but not limited to:


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


•	unexpected changes to currency policy or currency restrictions in foreign jurisdictions;


•	delays in collecting trade receivable balances from customers in developing economies;


•	tariffs and other trade barriers;


•	unexpected changes in regulatory requirements;


•	fluctuations in local economies;


•	disparate and changing employment laws in foreign jurisdictions;


•	difficulties in staffing and managing foreign operations;


•	costs and risks of localizing products for foreign countries;


•	government actions throughout the world; and


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

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.

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.

We Make Significant Investments in New Products that May Not Be Successful or Achieve Expected Returns. We plan to continue to make significant investments in research, development, and marketing for new and existing products and technologies. We have made and expect to make significant investments in software development related to the new and enhanced features of our products. These investments involve a number of risks as the commercial success of such efforts depend on many factors, including our ability to anticipate and respond to innovation, achieve the desired technological fit, and be effective with our marketing and distribution efforts. If our existing or potential customers do not perceive our latest product offerings as providing significant new functionality or value, or if we are late to market with a new product or technology, we may not achieve our expected return on our investments or be able recover the costs expended to develop new product offerings, which could have a material adverse effect on our operating results. Even if our new products are profitable, our operating margins for new products may not be as high as the margins we have experienced historically.

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.

Our Reported Financial Results May be Adversely Affected by Changes in Accounting Principles Generally Accepted in the U.S. 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 FASB and the Securities and Exchange Commission. Generally accepted accounting principles and accompanying accounting pronouncements, implementation guidelines and interpretations for many aspects of our business, such as revenue recognition, software capitalization, and income tax uncertainties, are complex and involve subjective judgments by management. A change in these policies or interpretations could have a significant effect on our reported financial results and our internal controls over financial reporting, may retroactively affect previously reported results, could cause unexpected financial reporting fluctuations, and may require us to make costly changes to our operational processes and accounting systems. For example, in February 2016, the FASB issued ASU 2016-02, Leases, as amended, supersedes nearly all existing U.S. GAAP lease guidance and which became effective for us for our fiscal year beginning January 1, 2019. (See Note 1 - Basis of presentation and Note 8 - Leases for additional discussion of the accounting changes).

Our Manufacturing Capacity, and a Substantial Majority of our Warehousing and Distribution Capacity is Located Outside of the U.S. We manufacture substantially all of our product volume at our facilities in Debrecen, Hungary and Penang, Malaysia. In order to enable timely shipment of products to our customers we maintain the substantial 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, but not limited to:


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


•	changing and potentially unstable political environments;


•	significant and frequent changes in corporate tax laws;


•	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;


•	restrictive labor codes; 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 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 failure or delay in distribution from our facilities in Hungary and Malaysia could have a material adverse effect on our operating results.

Our Financial Performance is Subject to Risks Associated with Changes in the Value of the U.S. Dollar versus Local Currencies. The vast majority of our sales outside of the U.S. 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. If the local currencies in which we sell our products strengthen against the U.S. dollar, we have in the past, and in the future may need to, lower our prices in the local currency to remain competitive in our international markets. This 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. 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 net sales and expenses and on the effectiveness of our hedging programs. In the past, these dynamics have also adversely affected our net sales growth in international markets and may pose similar challenges in the future. See “Results of Operations” in this Form 10-Q for further discussion on the effect that changes in the foreign currency exchange rates have had on our operating results. See “Current business outlook” in this Form 10-Q for information regarding recent business conditions.

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. We continue to make a concentrated effort to increase our net sales through the pursuit of orders with a value greater than $1.0 million. 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. At times these orders include terms that impose critical delivery commitments and severe contractual liabilities if we fail to provide the required quantity of products at the required delivery times, impose product acceptance requirements and product performance evaluation requirements which create uncertainty with respect to the timing of our ability to recognize revenue from such orders, allow the customers to cancel or delay orders without liability, require us to develop specific product mitigation plans for product delivery constraints caused by unexpected or catastrophic situations to help assure quick production recovery, and that require most favored customer pricing, significant discounts, extended payment terms and volume rebates. At times these customers require broad indemnity obligations and large direct and consequential damage provisions in the event we breach our contracts with them. At times these contracts 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.

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 orders from very large customers and to continue to grow our business. These arrangements expose us to significant additional legal and operational risks which could result in a material adverse impact on our business, results of operations and financial condition. 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. We attempt to manage these risks but there can be no assurance that we will be successful in our efforts.

Revenue Derived from Systems Orders Could Adversely Affect our Gross Margin and Could Lead to Greater Variability in our Quarterly Results. We consider orders with a value greater than $20,000 as being indicative of our systems business. These orders have been and may continue to be more sensitive to changes in the global industrial economy, subject to greater discount variability and such orders may be pushed-out or reduced at a faster pace during an economic downturn compared to orders valued at less than $20,000. To the extent that the amount of our net sales derived from systems 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. Large orders may also have an impact on the historical seasonal pattern of our net sales and our results of operations. Large orders 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.

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, energy, automated test equipment, and aerospace, defense and government. 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. We cannot predict when and to what degree contractions in these industries may occur; however, any sharp or prolonged contraction in one or more of these industries could have a material adverse effect on our business and results of operations.

Our Realignment Activities May be Disruptive to Our Operations and Negatively Impact Our Results of Operations.

We are currently implementing changes within our organization designed to enhance our ability to pursue market opportunities, accelerate our technology development initiatives, and improve operational efficiencies. Specifically, we are in the process of aligning certain aspects of our operations with our strategic focus on industry-specific applications where we believe our product platform can add the most value to our customers. In the short-term, these actions may lead to business disruptions, decreased productivity and unanticipated employee turnover which may have an adverse impact on our business and results of operations.

Concentrations of Credit Risk and Uncertain Conditions in the Global Financial Markets May Adversely Affect Our Business and Results 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 emerging markets. 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 Have Established a Budget and Variations from Our Budget Will Affect Our Financial Results. We have established an operating budget for fiscal 2019. 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 during the remainder of 2019 is less than the demand we anticipated in setting our fiscal year 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 net sales, our operating results could be adversely affected. Our spending could exceed our budget due to a number of factors, including, but not limited to:


•	continued foreign currency fluctuations;


•	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;


•	unanticipated costs related to acquisitions we may make; or


•	increased component costs resulting from vendors increasing their sales prices.

We Operate in Intensely Competitive Markets. The markets in which we operate are characterized by intense competition from numerous competitors, some of which have larger market capitalization and resources than we do, and we may face further competition from new market entrants in the future. Key competitors are Advantest, Anritsu, Fortive, Keysight, Rohde & Schwarz, Teradyne, and others. These competitors offer hardware and software products that provide solutions that directly compete with our software defined automated test and automated measurement systems. Because these companies have strong positions in the instrumentation business, new product introductions by them, changes in their marketing strategy or product offerings or aggressive pricing strategies by them to gain market share could have a material adverse effect on our operating results.

We believe our ability to compete successfully depends on a number of factors both within and outside our control, including, but not limited to:


•	general market and economic conditions;


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


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

•	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.

Our Quarterly Results are Subject to Fluctuations Due to Various Factors that May Adversely Affect Our Business and Results 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, but not limited to:


•	tariffs and trade restrictions imposed by the U.S. or other countries;


•	fluctuations in foreign currency exchange rates;


•	changes in global economic conditions;


•	changes in the amount of revenue derived from very large orders (including orders from our very large customers) and the pricing, margins, and other terms of such orders;


•	changes in the capacity utilization including at our facility in Malaysia;


•	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 caused by human error or other factors; or,


•	disruptions in transportation channels.

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 very large customers, 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.

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. 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. Our tax years 2012 through 2019 remain open to examination by the major taxing jurisdictions to which we are subject.

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 have 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 research and development 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 research and development, 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 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.

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 operations 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. Our earnings in Hungary are subject to a statutory tax rate of 9%. In addition, effective January 1, 2010, certain qualified research and development expenses in Hungary became eligible for an enhanced tax deduction. These tax benefits may not be available in future years due to changes in political conditions in Hungary or changes in tax laws in Hungary or in the U.S. The reduction or elimination of these benefits in Hungary could result in an increase in our future effective income tax rate which could have a material adverse effect on our operating results. (See Note 9 - Income taxes of Notes to Consolidated Financial Statements for additional discussion regarding the impact of these matters on our income taxes).

Our Income Tax Rate Could be Adversely Affected by the Expiration of a Tax Holiday in Malaysia. Profits from our manufacturing facility in Penang, Malaysia are free of tax under a 15-year tax holiday effective January 1, 2013. 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 could have a material adverse effect on our operating results. (See Note 9 - Income taxes of Notes to Consolidated Financial Statements for additional discussion regarding the impact of this tax holiday on our income taxes).

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 items are only available through limited sources. Limited source items purchased include custom application-specific integrated circuits, chassis and other components. We have in the past experienced delays and quality problems in connection with limited source items, and there can be no assurance that these problems will not recur in the future. Accordingly, our failure to receive items from limited source item suppliers could result in a material adverse effect on our net sales 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, or an increase in manufacturing costs, any of which would have a material adverse impact on our operating results.

We Rely on Management Information Systems and Interruptions in our Information Technology Systems or Cyber-Attacks on our Systems Could Adversely Affect Our Business. We rely on the efficient and uninterrupted operation of complex information technology systems and networks, including cloud-based and other outsourced services, 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, facility issues, energy blackouts, and computer viruses, cyber-attacks, or security breaches, some of which may remain undetected for an extended period. Threats to our information technology security can take a variety of forms and individuals or groups of hackers or sophisticated organizations including state-sponsored organizations, may take steps that pose threats to our customers and our infrastructure. If we were to experience a shutdown, disruption or attack, it would adversely impact our product shipments and net sales, 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. In addition, changing laws and regulations governing our responsibility to safeguard private data could result in a significant increase in operating or capital expenditures needed to comply with these new laws or regulations. Accordingly, our operating results in such periods would be adversely impacted. From time to time, we have experienced attempts to breach our security and attempts to introduce malicious software into our information technology systems; however, such attacks have not previously resulted in any material damage to us.

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 the following: firewalls, antivirus protection, patches, log monitors, routine backups with offsite retention of storage media, system audits, data partitioning and routine password modifications. Our internal information technology systems environment continues to evolve and our business policies and internal security controls may not keep pace as new threats emerge. No assurance can be given that our efforts to continue to enhance our systems will be successful. Although we maintain insurance, 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.

We are Subject to Risks Associated with Our Website. We devote significant resources to maintaining our website, ni.com, as a key marketing, sales and support tool and expect to continue to do so in the future. Failure to properly maintain our website may interrupt our 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.

Our Products are Complex and May Contain Bugs, Vulnerabilities, Errors, or Design Flaws. As has occurred in the past and as may be expected to occur in the future, our hardware products, software products and third-party components or operating systems on which our products are based may contain bugs, vulnerabilities, errors or design flaws. Our products operate in conjunction with third-party products and components across a broad ecosystem. As has occurred in the past and as may be expected to occur in the future, our products, or products or components in conjunction with which they operate, may contain design flaws. These bugs, vulnerabilities, errors or design flaws, or fixes to these issues, may have a negative impact on the performance of our products, which could result in additional costs, liability claims, reduced revenue, or harm to our reputation or competitive position, any of which could have a material adverse impact on our operating results. Although we maintain insurance, 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.

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, bodily harm or property damage. 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” and electronically displayed 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 insurance, 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.

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, 2019. 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, 2018 and 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.

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 Business Depends on the Continued Service of Our 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 Alex Davern, our Chief Executive Officer, Eric Starkloff, our President and Chief Operating Officer, and other members of our senior management and key technical personnel. 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. The market for hiring and retaining certain technical personnel, including software engineers, has become more competitive and intense in recent years. Failure to attract and retain a sufficient number of qualified technical personnel, including software engineers, or retain our key personnel could have a material adverse effect on our operating results.

Our Operations are Subject to a Variety of Environmental Regulations and Costs that May Have a Material Adverse Effect on Our Business and Results of 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 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.

Provisions in Our Charter Documents and Delaware Law May Delay or Prevent an Acquisition of Us. Our certificate of incorporation, 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 our 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.
