Financial Assets and Liabilities that are Measured at Fair Value on a Recurring Basis | ||||||||
The following table summarizes the financial assets and liabilities required to be measured at fair value on a recurring basis as of March 30, 2014 (in thousands): | ||||||||
Quoted Prices in | Significant Other | |||||||
Active Markets | Observable | |||||||
for Identical | Inputs (Level 2) | |||||||

Liabilities: | ||||||||
Cash flow hedge forward contracts | — | 112 | ||||||
The Company’s money market instruments are reported at fair value based upon the daily market price for identical assets in active markets, and are therefore classified as Level 1. | ||||||||
The Company’s debt securities and forward contracts are reported at fair value based upon model-driven valuations in which all significant inputs are observable or can be derived from or corroborated by observable market data for substantially the full term of the asset or liability, and are therefore classified as Level 2. Management is responsible for estimating the fair value of these financial assets and liabilities, and in doing so, considers valuations provided by a large, third-party pricing service. For debt securities, this service maintains regular contact with market makers, brokers, dealers, and analysts to gather information on market movement, direction, trends, and other specific data. They use this information to structure yield curves for various types of debt securities and arrive at the daily valuations. The Company's forward contracts are typically traded or executed in over-the-counter markets with a high degree of pricing transparency. The market participants are generally large commercial banks. | ||||||||
The Company did not record an other-than-temporary impairment of these financial assets or liabilities during the three-month period ended March 30, 2014. | ||||||||
Financial Assets that are Measured at Fair Value on a Non-recurring Basis | ||||||||
The Company has an interest in a limited partnership, which is accounted for using the cost method and is required to be measured at fair value on a non-recurring basis. Management is responsible for estimating the fair value of this investment, and in doing so, considers valuations of the partnership’s investments as determined by the General Partner. Publicly-traded investments in active markets are reported at the market closing price less a discount, as appropriate, to reflect restricted marketability. Fair value for private investments for which observable market prices in active markets do not exist is based upon the best information available including the value of a recent financing, reference to observable valuation measures for comparable companies (such as revenue multiples), public or private transactions (such as the sale of a comparable company), and valuations for publicly-traded comparable companies. The valuations also incorporate the General Partner’s own judgment and close familiarity with the business activities of each portfolio company. Significant increases or decreases in any of these inputs in isolation may result in a significantly lower or higher fair value measurement. The portfolio consists of securities of public and private companies, and consequently, inputs used in the fair value calculation are classified as Level 3. The Company did not record an other-than-temporary impairment of this asset during the three-month period ended March 30, 2014. | ||||||||
Non-financial Assets that are Measured at Fair Value on a Non-recurring Basis | ||||||||
Non-financial assets such as goodwill, intangible assets, and property, plant, and equipment are required to be measured at fair value only when an impairment loss is recognized. The Company did not record an impairment charge related to these assets during the three-month period ended March 30, 2014. |

Warranty Obligations | ' | |||
The Company records the estimated cost of fulfilling product warranties at the time of sale based upon historical costs to fulfill claims. Obligations may also be recorded subsequent to the time of sale whenever specific events or circumstances impacting product quality become known that would not have been taken into account using historical data. While we engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers and third-party contract manufacturers, the Company’s warranty obligation is affected by product failure rates, material usage, and service delivery costs incurred in correcting a product failure.

In May 2008, the Company filed a complaint against MvTec Software GmbH, MvTec LLC, and Fuji America Corporation in the United States District Court for the District of Massachusetts alleging infringement of certain patents owned by the Company. This matter is ongoing. | |
In May 2009, the Company pre-filed a complaint with the United States International Trade Commission (ITC) pursuant to Section 337 of the Tariff Act of 1930, as amended, 19 U.S.C. §1337, against MvTec Software GmbH, MvTec LLC, Fuji America, and several other respondents alleging unfair methods of competition and unfair acts in the unlawful importation into the United States, sale for importation, or sale within the United States after importation. By this filing, the Company requested the ITC to investigate the Company’s contention that certain machine vision software, machine vision systems, and products containing the same infringe, and respondents directly infringe and/or actively induce and/or contribute to the infringement in the United States, of one or more of the Company’s U.S. patents. In July 2009, the ITC issued an order that it would institute an investigation based upon the Company’s assertions. In September 2009, the Company reached a settlement with two of the respondents, and in December 2009, the Company reached a settlement with five additional respondents. In March 2010, the Company reached a settlement with respondent Fuji Machine Manufacturing Co., Ltd. and its subsidiary Fuji America Corporation. These settlements did not have a material impact on the Company’s financial results. An ITC hearing was held in May 2010. In July 2010, the Administrative Law Judge issued an initial determination finding two of the Company’s patents invalid and that respondents did not infringe the patents-at-issue. In September 2010, the ITC issued a notice that it would review the initial determination of the Administrative Law Judge. The ITC issued its Final Determination in November 2010 in which it determined to modify-in-part and affirm-in-part the Administrative Law Judge’s determination, and terminate the investigation with a finding of no violation of Section 337 of the Tariff Act of 1930 (as amended 19 U.S.C. §1337). The Company has filed an appeal of the decision with the United States Court of Appeals for the Federal Circuit. An oral hearing before the United States Court of Appeals occurred in February 2012. In December 2013, the Federal Circuit affirmed the ITC’s finding of non-infringement, but did not address the ITC’s finding regarding validity. | |
In March 2013, the Company filed a lawsuit against Microscan Systems, Inc. (“Microscan”) and Code Corporation in the United States District Court for the Southern District of New York alleging that Microscan’s Mobile Hawk handheld imager infringes U.S. Patent 7,874,487 owned by the Company. The lawsuit seeks to prohibit Code Corporation from manufacturing the product, and Microscan from selling and distributing the product. The Company is also seeking monetary damages resulting from the alleged infringement. Both parties have filed motions for summary judgment and a hearing on these motions was held in October 2013. Trial was originally scheduled for October 2013, but has been moved to April 2014. This matter is ongoing. | |
The Company cannot predict the outcome of the above-referenced pending matters and an adverse resolution of these lawsuits could have a material adverse effect on the Company’s financial position, liquidity, results of operations, and/or indemnification obligations. In addition, various other claims and legal proceedings generally incidental to the normal course of business are pending or threatened on behalf of or against the Company. While we cannot predict the outcome of these incidental matters, we believe that any liability arising from them will not have a material adverse effect on our financial position, liquidity, or results of operations. |

Guarantees | ' | ||||||
In the ordinary course of business, the Company enters into guarantee contracts with certain customers, generally in the Company’s Surface Inspection Systems Division (SISD) business. These guarantees represent standby letters of credit (LOC) which can be grouped into three categories: (1) bank guarantees which may require the Company to return a customer’s initial payment if the Company cannot deliver the order; (2) warranty bonds which may require the Company to resolve warranty issues within a specified time period; and (3) performance bonds which include a combination of the above two options. The type of LOC is generally determined based upon customer request and the guarantee amount represents the maximum potential amount of future payments. All of the Company’s LOCs are with the same counterparty and they do not contain any recourse provisions or collateral obligations. | |||||||
The following table details the letters of credit outstanding as of March 30, 2014: | |||||||

The Company evaluates losses for guarantees under accounting for contingencies. The Company considers such factors as the degree of probability that the Company would be required to satisfy the guarantee and the ability to make a reasonable estimate of the loss. To date, the Company has not incurred any losses as a result of these obligations, and therefore, has not recorded any liability related to such obligation in its financial statements. The fair value of the Company’s outstanding guarantees is immaterial for all periods presented. |

Indemnification Provisions | ' |
Except as limited by Massachusetts law, the by-laws of the Company require it to indemnify certain current or former directors, officers, and employees of the Company against expenses incurred by them in connection with each proceeding in which he or she is involved as a result of serving or having served in certain capacities. Indemnification is not available with respect to a proceeding as to which it has been adjudicated that the person did not act in good faith in the reasonable belief that the action was in the best interests of the Company. The maximum potential amount of future payments the Company could be required to make under these provisions is unlimited. The Company has never incurred significant costs related to these indemnification provisions. As a result, the Company believes the estimated fair value of these provisions is minimal. | |
In the ordinary course of business, the Company may accept standard limited indemnification provisions in connection with the sale of its products, whereby it indemnifies its customers for certain direct damages incurred in connection with third-party patent or other intellectual property infringement claims with respect to the use of the Company’s products. The term of these indemnification provisions generally coincides with the customer’s use of the Company’s products. The maximum potential amount of future payments the Company could be required to make under these provisions is generally subject to fixed monetary limits. The Company has never incurred significant costs to defend lawsuits or settle claims related to these indemnification provisions. As a result, the Company believes the estimated fair value of these provisions is minimal. | |
In the ordinary course of business, the Company also accepts limited indemnification provisions from time to time, whereby it indemnifies customers for certain direct damages incurred in connection with bodily injury and property damage arising from the installation of the Company’s products. The term of these indemnification provisions generally coincides with the period of installation. The maximum potential amount of future payments the Company could be required to make under these provisions is generally limited and is likely recoverable under the Company’s insurance policies. As a result of this coverage, and the fact that the Company has never incurred significant costs to defend lawsuits or settle claims related to these indemnification provisions, the Company believes the estimated fair value of these provisions is minimal. |

Derivative Instruments | ' | |||||||||||||||||||
The Company is exposed to certain risks relating to its ongoing business operations including foreign currency exchange rate risk and interest rate risk. The Company currently mitigates certain foreign currency exchange rate risks with derivative instruments. The Company does not currently manage its interest rate risk with derivative instruments. | ||||||||||||||||||||
The Company faces exposure to foreign currency exchange rate fluctuations, as a significant portion of its revenues, expenses, assets, and liabilities are denominated in currencies other than the functional currencies of the Company’s subsidiaries or the reporting currency of the Company, which is the U.S. Dollar. The Company faces two types of foreign currency exchange rate exposures: | ||||||||||||||||||||
• | Transactional currency/functional currency exchange rate exposures from transactions that are denominated in currencies other than the functional currency of the subsidiary. These transaction gains and losses are reported in "Foreign currency gain (loss)" on the Consolidated Statements of Operations. | |||||||||||||||||||
• | Functional currency/reporting currency exchange rate exposures from the revaluation of the assets and liabilities of our foreign subsidiaries, whose functional currency is generally their local currency, to the Company’s reporting currency, which is the U.S. Dollar. These translation gains and losses are reported in “Accumulated other comprehensive loss” on the Consolidated Balance Sheets and also on the Consolidated Statements of Comprehensive Income. | |||||||||||||||||||
The Company’s foreign currency risk management strategy is principally designed to mitigate the potential financial impact of changes in the value of transactions and balances denominated in foreign currencies resulting from changes in foreign currency exchange rates. Currently, the Company enters into two types of hedges to manage this risk. The first are economic hedges which utilize foreign currency forward contracts with maturities of up to 45 days to manage the exposure to fluctuations in foreign currency exchange rates arising primarily from foreign-denominated receivables and payables. The gains and losses on these derivatives are largely offset by changes in the fair value of the assets and liabilities being hedged. The second are cash flow hedges which utilize foreign currency forward contracts with maturities of up to 18 months to hedge specific forecasted transactions of the Company's foreign subsidiaries with the goal of protecting our budgeted revenues and expenses against foreign currency exchange rate changes compared to our budgeted rates. | ||||||||||||||||||||

The Company’s share-based payments that result in compensation expense consist solely of stock option grants. As of March 30, 2014, the Company had 10,024,230 shares available for grant. Generally, stock options are granted with an exercise price equal to the market value of the Company’s common stock at the grant date, vest over four years based upon continuous service, and expire ten years from the grant date. | |||||||||||||

(1) In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the future. Options expected to vest are calculated by applying an estimated forfeiture rate to the unvested options. | |||||||||||||
The fair values of stock options granted in each period presented were estimated using the following weighted-average assumptions: | |||||||||||||
Three-months Ended | |||||||||||||
30-Mar-14 | 31-Mar-13 | ||||||||||||
Risk-free rate | 2.7 | % | 2.1 | % | |||||||||
Expected dividend yield | — | % | — | % | |||||||||
Expected volatility | 41 | % | 42 | % | |||||||||
Expected term (in years) | 5.4 | 5.9 | |||||||||||
Risk-free rate | |||||||||||||
The risk-free rate was based upon a treasury instrument whose term was consistent with the contractual term of the option. | |||||||||||||
Expected dividend yield | |||||||||||||
Generally, the current dividend yield is calculated by annualizing the cash dividend declared by the Company’s Board of Directors and dividing that result by the closing stock price on the grant date. However, in the fourth quarter of 2012, the Company paid the full annual dividends for 2013 and 2014 in advance, and therefore, the dividend yield for those years has been adjusted to zero. At the time of the 2014 valuation, a dividend yield of 0.56% was estimated for future periods from 2015 through the expected life of the option. | |||||||||||||
Expected volatility | |||||||||||||
The expected volatility was based upon a combination of historical volatility of the Company’s common stock over the contractual term of the option and implied volatility for traded options of the Company’s stock. | |||||||||||||
Expected term | |||||||||||||
The expected term was derived from the binomial lattice model from the impact of events that trigger exercises over time. | |||||||||||||
The weighted-average grant-date fair values of stock options granted during the three-month periods ended March 30, 2014 and March 31, 2013 were $15.34 and $8.07, respectively. | |||||||||||||
The Company stratifies its employee population into two groups: one consisting of senior management and another consisting of all other employees. The Company currently expects that approximately 72% of its stock options granted to senior management and 70% of its options granted to all other employees will actually vest. Therefore, the Company currently applies an estimated annual forfeiture rate of 11% to all unvested options for senior management and a rate of 12% for all other employees. The Company revised its estimated forfeiture rates in the first quarters of 2014 and 2013, resulting in an increase to compensation expense of $288,000 and $300,000, respectively. | |||||||||||||
The total stock-based compensation expense and the related income tax benefit recognized for the three-month period ended March 30, 2014 were $4,004,000 and $1,306,000, respectively, and for the three-month period ended March 31, 2013 were $3,298,000 and $1,094,000, respectively. No compensation expense was capitalized as of March 30, 2014 or December 31, 2013. | |||||||||||||

Stock Repurchase Program | ' |
In April 2008, the Company’s Board of Directors authorized the repurchase of up to $50,000,000 of the Company’s common stock, primarily as a means to reduce the dilutive effect of employee stock options. Stock repurchases under this program were completed in 2013. In November 2011, the Company’s Board of Directors authorized the repurchase of up to $80,000,000 of the Company’s common stock to help reduce the dilutive effect of employee stock options. Purchases under this 2011 program began in 2013 upon completion of the 2008 program. As of March 30, 2014, the Company repurchased a total of 1,272,000 shares at a cost of $42,195,000, including 380,000 shares at a cost of $14,287,000 in the first quarter of 2014. On April 29, 2014, the Company's Board of Directors authorized the repurchase of an additional $50,000,000 of the Company's stock. This new authorization will commence once the Company completes the November 2011 program. The Company may repurchase shares under this program in future periods depending upon a variety of factors, including, among other things, the impact of dilution from employee stock options, stock price, share availability, and cash requirements. |

A reconciliation of the United States federal statutory corporate tax rate to the Company’s effective tax rate, or income tax provision, was as follows: | ||||||
Three-months Ended | ||||||

Discrete tax events | — | % | (3 | )% | ||
Income tax provision | 19 | % | 16 | % | ||
The effective tax rate for the three-month period ended March 31, 2013 included a discrete event that decreased tax expense by $555,000, net of related reserves for income taxes, from the retroactive application of the 2012 research and development credit. The American Taxpayer Relief Act of 2012 was passed by Congress and signed into law on January 1, 2013. The provisions under this law were applied retroactively to January 1, 2012. As a result of the law being signed on January 1, 2013, the financial impact of the retroactive provision was recorded as a discrete event in the first quarter of 2013. This discrete tax event decreased the effective tax rate from a provision of 19% to a provision of 16% for the first quarter of 2013. | ||||||
During the three-month period ended March 30, 2014, the Company recorded a $175,000 increase in reserves for income taxes, net of deferred tax benefit, for uncertain tax positions that were recorded as income tax expense. Estimated interest and penalties included in these amounts totaled $40,000 for the three-month period ended March 30, 2014. | ||||||
In the first quarter of 2014, management adopted Accounting Standards Update (ASU) 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." This ASU requires companies to present an unrecognized tax benefit, or a portion thereof, as a reduction to a deferred tax asset for a net operating loss (NOL) carryforward or a similar tax loss or tax credit carryforward. During the three-month period ended March 30, 2014, the Company reclassified a reserve for income taxes of $1,028,000 as a reduction to noncurrent deferred tax assets in compliance with this new guidance. Retroactive application was not required under this ASU, and therefore, prior periods were not restated. | ||||||
The Company’s reserve for income taxes, including gross interest and penalties, was $4,967,000 as of March 30, 2014, which included $3,939,000 classified as a noncurrent liability and $1,028,000 recorded as a reduction to noncurrent deferred tax assets. The amount of gross interest and penalties included in these balances was $415,000. If the Company’s tax positions were sustained or the statutes of limitations related to certain positions expired, these reserves would be released and income tax expense would be reduced in a future period, less $451,000 that would be recorded through additional paid-in capital. As a result of the expiration of certain statutes of limitations and the conclusion of an IRS examination, there is a potential that a portion of these reserves could be released, which would decrease income tax expense by approximately $700,000 to $800,000 over the next twelve months. | ||||||
The Company has defined its major tax jurisdictions as the United States, Ireland, China, and Japan, and within the United States, Massachusetts and California. Within the United States, the tax years 2012 through 2013 remain open to examination by various taxing authorities, while the tax years 2009 through 2013 remain open to examination by various taxing authorities in other jurisdictions in which the Company operates. |
