Note 1 – Operations and summary of significant accounting policies

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

Principles of consolidation

The Consolidated Financial Statements include the accounts of National Instruments Corporation and its subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Use of estimates

The preparation of our financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Although these estimates are based on management's best knowledge of current events and actions that may impact the company in the future, actual results may be materially different from the estimates.

Cash and cash equivalents

Cash and cash equivalents include cash and highly liquid investments with maturities of three months or less at the date of acquisition.

Short-Term Investments

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 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 corporations and agencies as well as debt securities issued by foreign governments. All short-term investments available-for-sale have contractual maturities of less than 35 months.

Our investments are classified as available-for-sale and accordingly are reported at fair value, with unrealized gains and losses reported as other comprehensive income, a component of stockholders’ equity. Unrealized losses are charged against income when a decline in fair value is determined to be other than temporary. Investments with maturities beyond one year are classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. The fair value of our short-term investments in debt securities at December 31, 2013 and December 31, 2012 was $163 million and $173 million, respectively. The decrease was due to the net sale of $10 million of short-term investments. We have $17 million U.S. dollar equivalent of German government sovereign debt and $16 million U.S. dollar equivalent of corporate bonds that are denominated in Euro at December 31, 2013. Our German government sovereign debt holdings have a maximum remaining maturity of 18 months and carry Aaa/AAA ratings.

We follow the guidance provided by FASB ASC 320 to assess whether our investments with unrealized loss positions are other than temporarily impaired. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in other income (expense), net, in our Consolidated Statements of Income. We did not identify or record any other-than-temporary impairments during 2013, 2012 and 2011.

Accounts Receivable, net

Accounts receivable are recorded net of allowances for sales returns of $1.6 million and $2.1 million at December 31, 2013 and 2012, respectively, and net of allowances for doubtful accounts of $2.8 million and $2.8 million at December 31, 2013 and 2012, respectively. A provision for estimated sales returns is made by reducing recorded revenue based on historical experience. We analyze historical returns, current economic trends and changes in customer demand of our products when evaluating the adequacy of our sales returns allowance. Our allowance for doubtful accounts is based on historical experience. We analyze historical bad debts, customer concentrations, customer creditworthiness and current economic trends when evaluating the adequacy of our allowance for doubtful accounts.

2013	Allowance for doubtful accounts and sales returns	$	4,870	$	(43)	$	396	$	4,431

Inventories, net

Inventories are stated at the lower-of-cost or market. Cost is determined using standard costs, which approximate the first-in first-out (“FIFO”) method. Cost includes the acquisition cost of purchased components, parts and subassemblies, in-bound freight costs, labor and overhead. Market is replacement cost with respect to raw materials and is net realizable value with respect to work in process and finished goods.

Inventory is shown net of adjustment for excess and obsolete inventories of $5.5 million, $3.8 million and $4.2 million at December 31, 2013, 2012 and 2011, respectively.


(In thousands)
Year	Description		Balance at Beginning of Period		Provisions		Write-Offs		Balance at End of Period
2011	Adjustment for excess and obsolete inventories	$	3,340	$	3,554	$	2,689	$	4,205
2012	Adjustment for excess and obsolete inventories	$	4,205	$	1,824	$	2,185	$	3,844
2013	Adjustment for excess and obsolete inventories	$	3,844	$	3,488	$	1,873	$	5,459

Property and equipment, net

Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from twenty to forty years for buildings, three to seven years for purchased internal use software and for equipment which are each included in furniture and equipment. Leasehold improvements are depreciated over the shorter of the life of the lease or the asset.

Intangible assets, net

We capitalize costs related to the development and acquisition of certain software products. Capitalization of costs begins when technological feasibility has been established and ends when the product is available for general release to customers. Technological feasibility for our products is established when the product is available for beta release. Amortization is computed on an individual product basis for those products available for market and is recognized based on the product’s estimated economic life, generally three years.

We use the services of outside counsel to search for, document, and apply for patents. Those costs, along with any filing or application fees, are capitalized. Costs related to patents which are abandoned are written off. Once a patent is granted, the patent costs are amortized ratably over the legal life of the patent, generally ten to seventeen years.

At each balance sheet date, the unamortized costs for all intangible assets are reviewed by management and reduced to net realizable value when necessary.

Goodwill

The excess purchase price over the fair value of net assets acquired is recorded as goodwill. As we have one operating segment, we allocate goodwill to one reporting unit for goodwill impairment testing. Goodwill is tested for impairment on an annual basis, and between annual tests if indicators of potential impairment exist, using a fair-value-based approach based on the market capitalization of the reporting unit. Our annual impairment test was performed as of February 28, 2013. No impairment of goodwill was identified during 2013 and 2012. Goodwill is deductible for tax purposes in certain jurisdictions.

Concentrations of credit risk

We maintain cash and cash equivalents with various financial institutions located in many countries throughout the world. At December 31, 2013, $142 million or 62% of our cash and cash equivalents was held in cash in various operating accounts with financial institutions throughout the world, and $88 million or 38% was held in money market accounts. The most significant of our operating accounts was our domestic Wells Fargo operating account which held approximately $15 million or 6% of our total cash and cash equivalents at a bank that carried A+/A2/AA- ratings at December 31, 2013. From a geographic standpoint, approximately $69 million or 30% of our cash was held in various domestic accounts with financial institutions and $161 million or 70% was held in various accounts outside of the U.S. with financial institutions. At December 31, 2013, our short-term investments consist of $17 million or 11% of foreign government bonds, $72 million or 44% of U.S. treasuries and agencies, $71 million or 43% of corporate notes, and $3 million or 2% in time deposits.

The goal of our investment policy is to manage our investment portfolio to preserve principal and liquidity while maximizing the return on our investment portfolio through the full investment of available funds. We place our cash investments in instruments that meet credit quality standards, as specified in our corporate investment policy guidelines. These guidelines also limit the amount of credit exposure to any one issue, issuer or type of instrument. Our cash equivalents and short-term investments carried ratings from the major credit rating agencies that were in accordance with our corporate investment policy. Our investment policy allows investments in the following: government and federal agency obligations, repurchase agreements (“Repos”), certificates of deposit and time deposits, corporate obligations, medium term notes and deposit notes, commercial paper including asset-backed commercial paper (“ABCP”), puttable bonds, general obligation and revenue bonds, money market funds, taxable commercial paper, corporate notes/bonds, municipal notes, municipal obligations, variable rate demand notes and tax exempt commercial paper. All such instruments must carry minimum ratings of A1/P1/F1, MIG1/VMIG1/SP1 and A2/A/A, as applicable, all of which are considered “investment grade”. Our investment policy for marketable securities requires that all securities mature in three years or less, with a weighted average maturity of no longer than 18 months with at least 10% maturing in 90 days or less. (See Note 2 – Cash, cash equivalents, short-term and long-term investments in Notes to Consolidated Financial Statements for further discussion and analysis of our investments).

Concentration of credit risk with respect to trade accounts receivable is limited due to our large number of customers and their dispersion across many countries and industries. The amount of sales to any individual customer did not exceed 3%, 7%, or 4% of revenue for the years ended December 31, 2013, 2012, or 2011, respectively. The largest trade account receivable from any individual customer at December 31, 2013 was approximately $6.1 million.

Key supplier risk

Our manufacturing processes use large volumes of high-quality components and subassemblies supplied by outside sources. Several of these components are available through sole or limited sources. Supply shortages or quality problems in connection with some of these key components could require us to procure components from replacement suppliers, which would cause significant delays in fulfillment of orders and likely result in additional costs. In order to manage this risk, we maintain safety stock of some of these single sourced components and subassemblies and perform regular assessments of suppliers performance, grading key suppliers in critical areas such as quality and “on-time” delivery.

Revenue recognition

We sell test and measurement solutions that include hardware, software licenses, and related services. Our sales are generally made under standard sales arrangements with payment terms ranging from net 30 days in the United States to net 30 days and up to net 120 days in some international markets. We offer rights of return and standard warranties for product defects related to our products. The rights of return are generally for a period of up to 30 days after the delivery date. Our standard warranties cover periods ranging from 90 days to three years. Our standard sales arrangements do not require product acceptance from the customer.

In recent years, we have made a concentrated effort to increase our revenue through the pursuit of orders with a value greater than $1.0 million. These orders often include contract terms that vary substantially from our standard terms of sale including product acceptance requirements and product performance evaluations which create uncertainty with respect to the timing of our ability to recognize revenue from such orders. These orders may also include most-favored customer pricing, significant discounts, extended payment terms and volume rebates, all of which may create uncertainty with respect to the amount and timing of revenue recognized from such orders.

Sales of application software licenses include post-contract support services. Other services include customer training, customer support, and extended warranties.

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable, and collectability is reasonably assured. Delivery is considered to have occurred when title and risk of loss have transferred to the customer. For most of our hardware and software sales, title and risk of loss transfer upon delivery. For services we recognize revenue when the service is provided, except for extended warranties for which revenue is recognized ratably over the warranty period.

We enter into certain arrangements in which we deliver multiple products and/or services. These arrangements may include hardware, software, and services. We separate consideration in multiple-deliverable arrangements by allocating to all deliverables using the relative selling price method at the inception of an arrangement. Revenue allocated to each element is then recognized when the basic revenue recognition criteria for that element have been met. The relative selling price method allocates any discount in the arrangement proportionally to each deliverable on the basis of each deliverable’s selling price. The selling price used for each deliverable will be based on vendor-specific objective evidence (“VSOE”) if available, third–party evidence if VSOE is not available, or estimated selling price if neither VSOE nor third-party evidence is available.

Software revenue recognition rules are applied to software sold on a stand-alone basis, and to software sold as part of a multiple element arrangement with hardware where the software is not required to deliver the tangible product's essential functionality. Under these rules, when VSOE of fair value is not available for a delivered element but is available for the undelivered element of a multiple element arrangement, sales revenue is recognized on the date the product is shipped, using the residual method, with the portion deferred that is related to undelivered elements. Undelivered elements related to software are generally restricted to post contract support and training and education. The amount of revenue allocated to these undelivered elements is based on the VSOE of fair value for those undelivered elements. Deferred revenue due to undelivered elements is recognized ratably over the service period or when the service is completed. When VSOE of fair value is not available for the undelivered element of a multiple element arrangement, sales revenue for the entire sales contract value is generally recognized ratably over the service period of the undelivered element, generally 12 months or when the service is completed in accordance with the subscription method.

The application of revenue recognition standards requires judgment, including whether a software arrangement includes multiple elements, and if so, whether VSOE of fair value exists for those elements. Changes to the elements in a software arrangement, the ability to identify VSOE for those elements, the fair value of the respective elements, and changes to a product’s estimated life cycle could materially impact the amount of our earned and unearned revenue. Judgment is also required to assess whether future releases of certain software represent new products or upgrades and enhancements to existing products.

Product revenue

Our product revenue is generated predominantly from the sales of measurement and automation products. Our products consist of application software and hardware components together with related driver software.

Software maintenance revenue

Software maintenance revenue is post contract customer support that provides the customer with unspecified upgrades/updates and technical support.

Shipping and handling costs

Our shipping and handling costs charged to customers are included in net sales, and the associated expense is recorded in cost of sales.

Warranty reserve

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

The warranty reserve for the years ended December 31, 2013, 2012 and 2011 was as follows:



(In thousands)
		2013		2012		2011
Balance at the beginning of the period	$	1,435	$	1,271	$	921
Accruals for warranties issued during the period		3,737		2,270		2,954
Settlements made (in cash or in kind) during the period		(3,408)		(2,106)		(2,604)
Balance at the end of the period	$	1,764	$	1,435	$	1,271

Loss contingencies

We accrue for probable losses from contingencies including legal defense costs, on an undiscounted basis, when such costs are considered probable of being incurred and are reasonably estimable. We periodically evaluate available information, both internal and external, relative to such contingencies and adjust this accrual as necessary.

Advertising expense

We expense costs of advertising as incurred. Advertising expense for the years ended December 31, 2013, 2012 and 2011 was $13.7 million, $14.4 million and $14.7 million, respectively.

Foreign currency translation

The functional currency for our international sales operations is the applicable local currency. The assets and liabilities of these operations are translated at the rate of exchange in effect on the balance sheet date and sales and expenses are translated at average rates. The resulting gains or losses from translation are included in a separate component of other comprehensive income. Gains and losses resulting from re-measuring monetary asset and liability accounts that are denominated in a currency other than a subsidiary’s functional currency are included in net foreign exchange loss and are included in net income.

Foreign currency hedging instruments

All of our derivative instruments are recognized on the balance sheet at their fair value. We currently use foreign currency forward and purchased option contracts to hedge our exposure to material foreign currency denominated receivables and forecasted foreign currency cash flows.

On the date the derivative contract is entered into, we designate the derivative as a hedge of the variability of foreign currency cash flows to be received or paid (“cash flow” hedge) or as a hedge of our foreign denominated net receivable positions (“other derivatives”). Changes in the fair value of derivatives that are designated and qualify as cash flow hedges and that are deemed to be highly effective are recorded in other comprehensive income. These amounts are subsequently reclassified into earnings in the period during which the hedged transaction is realized. The gain or loss on the other derivatives as well as the offsetting gain or loss on the hedged item attributable to the hedged risk is recognized in current earnings under the line item “Net foreign exchange loss”. We do not enter into derivative contracts for speculative purposes.

We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and strategy for undertaking various hedge transactions at the inception of the hedge. This process includes linking all derivatives that are designated as cash flow hedges to specific forecasted transactions. We also formally assess, both at the hedge’s inception and on an ongoing basis, whether the hedging instruments are highly effective in offsetting changes in cash flows of hedged items.

We prospectively discontinue hedge accounting if (1) it is determined that the derivative is no longer highly effective in offsetting changes in the fair value of a hedged item (forecasted transactions); or (2) the derivative is de-designated as a hedge instrument, because it is unlikely that a forecasted transaction will occur. When hedge accounting is discontinued, the derivative is sold and the resulting gains and losses are recognized immediately in earnings.

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 basis 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. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact our financial position or our results of operations. In estimating future tax consequences, all expected future events are considered other than enactments of changes in tax laws or rates. 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. Our continuing policy is to recognize interest and penalties related to income tax matters in income tax expense.

Earnings per share

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

The reconciliation of the denominators used to calculate basic EPS and diluted EPS for the years ended December 31, 2013, 2012 and 2011 are as follows:



	Years ended December 31,
(In thousands)	2013	2012	2011
Weighted average shares outstanding-basic	124,558	121,973	119,836
Plus: Common share equivalents
Stock options, restricted stock units	1,013	1,004	1,384
Weighted average shares outstanding-diluted	125,571	122,977	121,220

Stock awards to acquire 43,640 shares, 986,503 shares, and 477,019 shares for the years ended December 31, 2013, 2012, and 2011 were excluded in the computations of diluted EPS because the effect of including the stock awards would have been anti-dilutive.

On January 21, 2011, our Board of Directors declared a 3 for 2 stock split which was effected as a stock dividend, and paid on February 21, 2011, to stockholders of record on February 4, 2011. All per share data and numbers of common shares, where appropriate, have been retroactively adjusted to reflect the stock split.

Stock-based compensation

We account for stock-based compensation plans, which are more fully described in Note 11 – Authorized shares of common and preferred stock and stock-based compensation plans, using a fair-value method and recognize the expense in our Consolidated Statement of Income.

Comprehensive income

Our comprehensive income is comprised of net income, foreign currency translation and unrealized gains and losses on forward and option contracts and securities available-for-sale. Comprehensive income for 2013, 2012 and 2011 was $82.2 million, $94.5 million and $91.3 million, respectively.

Recently Issued Accounting Pronouncements

In February 2013, the FASB issued Accounting Standards Update (“ASU”) No. 2013-02, Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income, which amends ASC 220, Comprehensive Income. The amended guidance requires entities to provide information about the amounts reclassified out of accumulated other comprehensive income by component. Additionally, entities are required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amended guidance does not change the current requirements for reporting net income or other comprehensive income. The amendments are effective prospectively for reporting periods beginning after December 15, 2012. We adopted this update in the first quarter of 2013. The adoption of ASU No. 2013-02 did not have a significant impact on the Company’s consolidated financial statements, but did amend the disclosures for accumulated other comprehensive income reclassified into income.

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