NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except per share data)

(Unaudited)

NOTE 1.    Basis of Presentation

The accompanying interim unaudited condensed consolidated financial statements have been prepared by Rudolph Technologies, Inc. (the “Company” or “Rudolph”) and in the opinion of management reflect all adjustments, consisting of normal recurring accruals, necessary for their fair presentation in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).  Preparing financial statements requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes.  Actual amounts could differ materially from those amounts.  The interim results for the three and nine month periods ended September 30, 2013 are not necessarily indicative of results to be expected for the entire year or any future periods.  This interim financial information should be read in conjunction with the financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 (“10-K”) filed with the Securities and Exchange Commission (“SEC”). The accompanying condensed consolidated balance sheet at December 31, 2012 has been derived from the audited consolidated financial statements included in the 10-K, but recast to reflect the impact of finalizing certain aspects of the purchase accounting of Azores Corporation, as described in Note 2, subsequent to December 31, 2012.

Reclassifications

Certain prior period amounts have been reclassified to conform to current financial statement presentation. These amounts include the reclassification of uncertain tax credit liabilities to deferred tax assets in the Condensed Consolidated Balance Sheets.

Recent Accounting Pronouncements

In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” The ASU requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this guidance is reflected in the Company's consolidated statements of financial position and cash flows.

In July 2013, the FASB issued ASU No. 2013-10, “Derivatives and Hedging (Topic 815): Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes (a consensus of the FASB Emerging Issues Task Force.” The ASU permits the Fed Funds Effective Swap Rate (OIS) to be used as a U.S. benchmark interest rate for hedge accounting purposes under Topic 850, in addition to UST and LIBOR. The amendments also remove the restriction on using different benchmark rates for similar hedges. This ASU is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The Company does not believe that this guidance will have a material impact on its consolidated financial position, results of operations, or cash flows.

In February 2013, the FASB issued ASU No. 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” The ASU requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. This ASU is effective prospectively for reporting periods beginning after December 15, 2012. The adoption of this amendment did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

NOTE 2.   Business Combinations

Tamar Technology

In April 2013, the Company announced that it had acquired specific assets of Tamar Technology, located in Newbury Park, California (Tamar acquisition). The Company paid $3,365 of the purchase price in cash and accrued an additional $6,198 for contingent consideration. The acquired business has been integrated into the Company’s inspection technology group.  The impact of the acquisition was not material to the Company’s consolidated financial position or results of operations.

Azores

In December 2012, the Company announced that it had acquired Azores Corporation, located in Wilmington, Massachusetts (Azores acquisition). The acquired business marks the Company's entry into the advanced packaging and flat panel display lithography markets and forms the Company’s lithography systems group. The impact of the acquisition was not material to the Company’s consolidated financial position or results of operations.

The Company made a preliminary allocation of the purchase price to the assets acquired and liabilities assumed as of the acquisition date for the Azores acquisition and the Tamar acquisition. For the period ended September 30, 2013, the Company finalized the purchase price allocation for Azores, with the exception of taxes, and recorded adjustments to goodwill and inventory. The Company recast its December 31, 2012 balance sheet to reflect these adjustments. The Company will finalize its analysis of the remaining purchase price allocation within the measurement period, not to exceed one year from the date of the acquisition, and therefore additional adjustments may occur.

NOTE 3.  Fair Value Measurements

The Company applies a three-level valuation hierarchy for fair value measurements. This hierarchy prioritizes the inputs into three broad levels.  Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability. Level 3 inputs are unobservable inputs based on management’s assumptions used to measure assets and liabilities at fair value. A financial asset’s or liability’s fair value measurement classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following tables provide the assets and liabilities carried at fair value measured on a recurring basis at September 30, 2013 and December 31, 2012:

Foreign currency forward contracts	268		—		268		—
Total Assets	$	65,231	$	—	$	64,885	$	346

Level 1 investments are based on quoted prices that are available in active markets.

The Company’s investments classified as Level 2 are valued using observable inputs to quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. The foreign currency forward contracts are primarily measured based on the foreign currency spot and forward rates quoted by the banks or foreign currency dealers. Available-for-sale debt securities prices are obtained from third party pricing providers, which models prices utilizing the above observable inputs, for each asset class.

Level 3 investments consist of an auction rate security and contingent consideration related to an acquisition for which the Company uses a discounted cash flow model to value these investments. The Level 3 assumptions used in the discounted cash flow model for the auction rate security included estimates of interest rates of 3.4%, timing of cash flows and expected holding periods. Changes in the unobservable input values would be unlikely to cause material changes in the fair value of the auction rate security. The Level 3 assumptions used in the discounted cash flow model for the contingent consideration included projected revenues, estimates of discount rates and timing of cash flows. A significant decrease in the projected revenues could result in a significantly lower fair value measurement for the contingent consideration.

This table presents a reconciliation for all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the nine months endedSeptember 30, 2013:

See Note 4 for additional discussion regarding the fair value of the Company’s marketable securities.

Fair Value of Other Financial Instruments

The carrying value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates fair value because of the short maturity of these instruments. The estimated fair value of these obligations is based, primarily, on a market approach, comparing the Company’s interest rates to those rates the Company believes it would reasonably receive upon re-entry into the market. Judgment is required to estimate the fair value, using available market information and appropriate valuation methods.

The Company’s convertible senior notes are not publicly traded. The estimated fair value of the Company’s convertible senior notes was valued using a discounted cash flow model. The Level 3 assumptions, based on data available at the valuation date used in preparing the discounted cash flow model included estimates of interest rates, timing and amount of cash flows and expected holding periods of the convertible senior notes. The fair value of the contingent interest associated with the convertible senior notes is valued quarterly using the present value of expected cash flow model incorporating the probabilities of the contingent events occurring.

The following table reflects information pertaining to the Company’s convertible senior notes:

	September 30, 2013			December 31, 2012
Net carrying value of convertible senior notes	$	51,047		$	49,010
Estimated fair value of convertible senior notes	$	52,308		$	51,018
Estimated interest rate used in discounted cash flow model	9.4		%	9.4		%
Fair value of contingent interest	$	—		$	—

NOTE 4.   Marketable Securities

The Company has evaluated its investment policies and determined that all of its investment securities are to be classified as available-for-sale.  Available-for-sale securities are carried at fair value, with the unrealized gains and losses reported in Stockholders’ Equity under the caption “Accumulated other comprehensive loss.”  Realized gains and losses on available-for-sale securities are included in “Other expense (income)” in the Condensed Consolidated Statements of Operations.  The Company records other-than-temporary impairment charges for its available-for-sale investments when it intends to sell the securities, it is more-likely-than not that it will be required to sell the securities before a recovery, or when it does not expect to recover the entire amortized cost basis of the securities.  The cost of securities sold is based on the specific identification method.

8

As of September 30, 2013, the Company held one auction rate security with a fair value of $291. The underlying asset of the Company’s auction rate security consisted of a municipal bond with an auction reset feature. Due to auction failures in the marketplace, the Company will not have access to these funds unless (a) future auctions occur and are successful, (b) the security is called by the issuer, (c) the Company sells the security in an available secondary market, or (d) the underlying note matures. Currently, there are no active secondary markets. As of September 30, 2013, the Company had recorded a cumulative temporary unrealized impairment loss of $184 within “Accumulated other comprehensive loss” based upon its assessment of the fair value of this security. The Company believes that this impairment is temporary, as it does not intend to sell this security, the Company will not be required to sell this security before recovery, and the Company expects to recover the amortized cost basis of this security.

The Company has determined that the gross unrealized losses on its marketable securities at September 30, 2013 and December 31, 2012 are temporary in nature. The Company reviews its investment portfolio to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the cost basis, credit quality and the Company’s ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value.

At September 30, 2013 and December 31, 2012, marketable securities are categorized as follows:

	Amortized Cost		Gross Unrealized Holding Gains		Gross Unrealized Holding Losses			Fair Value
September 30, 2013
Municipal notes and bonds	$	73,975	$	47	$	(3	)	$	74,019
Corporate bonds	501		—		—			501
Auction rate securities	475		—		(184		)	291
Total marketable securities	$	74,951	$	47	$	(187	)	$	74,811
December 31, 2012
Municipal notes and bonds	$	64,088	$	36	$	(7	)	$	64,117
Corporate bonds	500		—		—			500
Auction rate securities	475		—		(129		)	346
Total marketable securities	$	65,063	$	36	$	(136	)	$	64,963

 The amortized cost and estimated fair value of marketable securities classified by the maturity date listed on the security, regardless of the Condensed Consolidated Balance Sheet classification, is as follows at September 30, 2013 and December 31, 2012:

	September 30, 2013				December 31, 2012
	Amortized Cost		Fair Value		Amortized Cost		Fair Value
Due within one year	$	65,676	$	65,710	$	57,367	$	57,390
Due after one through five years	8,800		8,810		7,016		7,022
Due after five through ten years	—		—		205		205
Due after ten years	475		291		475		346
Total marketable securities	$	74,951	$	74,811	$	65,063	$	64,963

The following table summarizes the estimated fair value and gross unrealized holding losses of marketable securities, aggregated by investment instrument and period of time in an unrealized loss position at September 30, 2013 and December 31, 2012:

See Note 3 for additional discussion regarding the fair value of the Company’s marketable securities.

NOTE 5.    Derivative Instruments and Hedging Activities

The Company, when it considers it to be appropriate, enters into forward contracts to hedge the economic exposures arising from foreign currency denominated transactions. At September 30, 2013 and December 31, 2012, these contracts included the future sale of Japanese Yen to purchase U.S. dollars. Derivative instruments are recognized as either “Prepaid expenses and other current assets” or “Other current liabilities” in the Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Cash Flows and are measured at fair value. The foreign currency forward contracts were entered into by the Company’s Japanese subsidiary to economically hedge a portion of certain intercompany obligations. The forward contracts are not designated as hedges for accounting purposes and therefore, decreases in the fair value of $259 and $241 for the nine month periods ended September 30, 2013 and 2012, respectively, are recorded within the caption “Other expense (income)” in the Condensed Consolidated Statements of Operations.

NOTE 8.   Debt Obligations

On July 25, 2011, the Company issued $60,000 aggregate principal amount of 3.75% Convertible Senior Notes due 2016 (the “Notes”) at par. The Notes were issued pursuant to an indenture, dated as of July 25, 2011, between the Company and Bank of New York Mellon Trust Company, N.A., as Trustee, which includes a form of Note. The Notes provide for the payment of interest semi-annually in arrears on January 15 and July 15 of each year, beginning January 15, 2012, at an annual rate of 3.75% and will mature on July 15, 2016, unless earlier converted or repurchased. The Notes may be converted, under certain circumstances, based on an initial conversion rate of 77.241 shares of Company common stock per $1 principal amount of Notes, which represents an initial conversion price of approximately $12.95 per share. Concurrently with the issuance of the Notes, the Company purchased a convertible note hedge and sold a warrant. Each of the convertible note hedge and warrant transactions were entered into with an affiliate of the initial purchaser of the Notes. The convertible note hedge is intended to reduce the potential future dilution to the Company’s common stock associated with the conversion of the Notes. However, the warrant transaction will have a dilutive effect on the Company’s earnings per share to the extent that the price of the Company’s common stock exceeds the strike price of the warrant. The strike price of the warrant will initially be $17.00 per share. The net proceeds to the Company from the sale of the Notes, including the convertible note hedge and warrant were $50,249.

The following table reflects the net carrying value of the Notes:

	September 30, 2013		December 31, 2012
Convertible senior notes	$	60,000	$	60,000
Less: Unamortized interest discount	8,953		10,990

NOTE 9.   Commitments and Contingencies

Warranty Reserves

The Company generally provides a warranty on its products for a period of twelve to fifteen months against defects in material and workmanship. The Company estimates the costs that may be incurred during the warranty period and records a liability in the amount of such costs at the time revenue is recognized. The Company’s estimate is based primarily on historical experience. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. Settlements of warranty reserves are generally associated with sales that occurred during the 12 to 15 months prior to the year-end and warranty accruals are related to sales during the year.

Changes in the Company’s warranty reserves are as follows:

	Nine Months Ended September 30,
	2013			2012
Balance, beginning of the period	$	2,024		$	1,406
Accruals	1,511			1,616
Warranty liability assumed in acquisition	—			93
Usage	(2,018		)	(1,535		)
Balance, end of the period	$	1,517		$	1,580

Warranty reserves are reported in the Condensed Consolidated Balance Sheets within the caption “Accounts payable and accrued liabilities.”

Letter of Credit

As of September 30, 2013, the Company had a $40,000 irrevocable standby letter of credit with Credit Suisse AG available to secure the damages assessment in connection with the ITC litigation discussed in Legal Matters below, which the Company is in the process of appealing. The letter of credit expires on February 25, 2014 with provisions for automatic renewal. Upon draw down of funds, the letter of credit would be collateralized by securities held in the Company’s investment portfolios and reported in the Condensed Consolidated Balance Sheets within the caption “Cash and cash equivalents” and “Marketable securities.” No amounts were outstanding on the letter of credit as of, or during the nine months ended, September 30, 2013.

Legal Matters

From time to time, the Company is subject to legal proceedings and claims in the ordinary course of business. As previously disclosed, in December 2007, the Company completed the acquisition of specific assets and liabilities of the semiconductor division of Applied Precision LLC (“Applied”). As a result of the acquisition, the Company assumed certain liabilities of Applied including a lawsuit filed in the United States District Court, District of Arizona, by Integrated Technology Corporation (“ITC”) which alleged Applied’s PrecisionPoint^™, PrecisionWoRx^® and ProbeWoRx^® products infringed an ITC patent (Integrated Technology Corporation v. Rudolph Technologies, Inc., No. CV-06-2182-PHX-ROS). Prior to trial, the District Court ruled that such products soldprior to August of 2007 infringed the ITC patent. In December 2011, a trial verdict was rendered in which the jury found that while the Company’s products manufactured after August of 2007 did not literally infringe ITC’s patent, the products were found to infringe under a rule known as the doctrine of equivalents, a legal principle which expands the scope of patent claims to encompass products or processes which may otherwise be found not to literally infringe the patent. The jury awarded $15,475 to ITC in damages for sales made during the years 2000-2011, of which award approximately one-half related to sales made after August 2007. The jury found that for sales made after August of 2007 the infringement was willful. On July 23, 2012, the District

13

Court, responding to post-trial motions filed by the Company and ITC related to the verdict and damages assessment, issued an Order which affirmed the jury’s award, applied treble damages to the portion of the jury award related to sales of the products after 2007 and granted ITC’s motion for attorney's fees and prejudgment interest on the verdict and attorney’s fees. The District Court also enjoined the Company from future infringement of the ITC patent and from selling or supplying the applicable products with the applicable features from or into the United States. The Company appealed the injunction as well as the District Court Order and the damages assessment. In October 2012, the injunction was stayed by the Federal Court of Appeals.  In November 2013, the U.S. Federal Court of Appeals issued a ruling reversing the findings of infringement under the doctrine of equivalents and willfulness regarding the post-August 2007 products, vacating the damages awards regarding these products.  In addition, the Appeals Court vacated the award of attorney’s fees and remanded the matter to the District Court to reassess its findings on this issue in the absence of willfulness.  Finally, the Appeals Court affirmed the damages assessed against the pre-August 2007 products.  The Company is currently assessing its options regarding this final ruling as the Company believes that its position on the pre-2007 damages is meritorious and shall continue to vigorously pursue this matter.  With the Appeals Court ruling, Rudolph’s post-August 2007 products have been found to not have infringed ITC’s patent, literally or under the doctrine of equivalents, so therefore no damages are assessed against Rudolph for these products. With regard to products soldbefore August of 2007, it is probable that the Company could realize a loss in this matter for which the Company has estimated and recorded a liability of approximately $4,293 in “Other liabilities” in the Consolidated Balance Sheets. The maximum liability reasonably possible for the pre-August 2007 products is an additional $3,391 plus interest beyond the accrual. While the Company continues to believe that its current PrecisionWoRx® and ProbeWoRx® systems do not infringe ITC’s patent, the Company reached an agreement with ITC in October 2012 with regards to a redesign of the products under which ITC agreed that such redesign is permissible under the court’s injunction.

In the Company’s patent infringement suit against Camtek, Ltd., of Migdal Hamek, Israel, concerning the Company’s proprietary continuous scan wafer inspection technology, the U.S. Federal Court of Appeals issued a ruling on August 22, 2011.  In its opinion, the Appellate Court affirmed multiple rulings from trial at the District Court level including (i) finding the Company’s U.S. Patent No. 6,826,298 valid, (ii) the part of the infringement ruling based on the finding that Camtek’s Falcon product strobes “based on velocity,” and (iii) the dismissal of Camtek’s claim against the Company for inequitable conduct against the U.S. Patent and Trademark Office.  The court did, however, revise one claim construction ruling made by the District Court in the original case.  As a result, the Appellate Court set aside the verdict delivered by the jury for damages and the District Court’s decision to enter an injunction against Camtek’s selling Falcon tools in the U.S. and remanded the case back to the trial court for a limited trial on this single infringement issue.  No trial date has been set for this limited trial.  This lawsuit was initially brought in 2005 by August Technology prior to its merger with the Company.

NOTE 10.   Share-Based Compensation

Valuation Assumptions for Stock Options

For the nine month period ended September 30, 2013, there were no stock options granted. There were 10 stock options granted in the nine month period ended September 30, 2012. The fair value of each option was estimated on the date of grant for the granted options using the Black-Scholes option-pricing model with the following assumptions:

	Nine Months Ended
	September 30,
	2012
Expected life (years)	5.0
Expected volatility	86.1		%
Expected dividend yield	—		%
Risk-free interest rate	0.8		%
Weighted average fair value per option	$	5.77

As of September 30, 2013 and December 31, 2012, there was $1,277 and $1,813 of total unrecognized compensation cost related to stock options granted under the Company’s stock plans, respectively. That cost is expected to be recognized over a weighted average period of 3.3 years and 4.0 years for the respective periods.

Restricted Stock Unit Activity

A summary of the Company’s nonvested restricted stock unit activity with respect to the nine months ended September 30, 2013 is as follows:

14

	Number of Shares		Weighted Average Grant Date Fair Value
Nonvested at December 31, 2012	1,380		$	8.37
Granted	327		$	12.40
Vested	(468	)	$	7.75
Forfeited	(54	)	$	9.50
Nonvested at September 30, 2013	1,185		$	9.68

As of September 30, 2013 and December 31, 2012, there was $7,179 and $5,906 of total unrecognized compensation cost related to restricted stock units granted under the Company’s stock plans, respectively.  That cost is expected to be recognized over a weighted average period of 2.3 years and 2.0 years for the respective periods.

Total other expense (income)	$	(4	)	$	357	$	(53	)	$	253

NOTE 12.   Income Taxes

The following table provides details of income taxes:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2013			2012			2013			2012
Income before income taxes	$	37		$	10,571		$	1,114		$	23,375
Provision (benefit) for income taxes	$	(215	)	$	3,910		$	(290	)	$	8,506
Effective tax rate	(581.1		)%	37.0		%	(26.0		)%	36.4		%

The income tax provision for the three and nine months endedSeptember 30, 2013 was computed based on the Company’s annual forecast of profit by jurisdiction and forecasted effective tax rate for the year. The changes in the Company’s effective tax rate for the nine months endedSeptember 30, 2013 compared to the same period for the prior year are primarily due to anticipated generation of federal R&D credits for both 2012 and 2013 recognized in 2013, which were not available in the 2012 period as a result of legislation. The changes in the effective tax rate for the three months endedSeptember 30, 2013 compared to the same period for the prior year are primarily due to the impact of tax credits and lower annual profit projections.

The Company currently has a partial valuation allowance recorded against certain deferred tax assets. Each quarter, the Company assesses the likelihood that it will be able to recover its deferred tax assets. The Company considers available evidence, both positive and negative, including prudent and feasible tax planning strategies in assessing the need for a valuation allowance. As a result of the Company’s analysis, it concluded that it is more likely than not that a portion of its deferred tax assets will not be realized. Therefore, the Company continues to provide a valuation allowance against certain deferred tax assets. The Company continues to closely monitor available evidence and may reverse some or all of the remaining valuation allowance in future periods, if appropriate. The Company has a valuation allowance of $1,361 as of September 30, 2013 and December 31, 2012.

In the normal course of business, the Company is subject to examination by taxing authorities throughout the world. The Company is currently under a federal income tax examination by the Internal Revenue Service for the tax years ended December 31, 2007 through December 31, 2009. In addition, the Company is under examination by the State of New York for the tax years 2009 through 2011. The Company has not been contacted by any other U.S. state, local or foreign tax authority for all open tax periods beginning after December 31, 2007.

NOTE 13.   Earnings Per Share

15

Basic earnings per share is calculated using the weighted average number of shares of common stock outstanding during the period.  Diluted earnings per share is computed in the same manner and also gives effect to all dilutive common equivalent shares outstanding during the period.  Potential common shares that would have the effect of increasing diluted earnings per share are considered to be antidilutive. In accordance with U.S. GAAP, these shares were not included in calculating diluted earnings per share. For the three and nine months endedSeptember 30, 2013, the weighted average number of stock options and restricted stock units excluded from the computation of diluted earnings per share was 672 and 731, respectively, because their effect was antidilutive. For the three and nine months endedSeptember 30, 2012, the weighted average number of stock options and restricted stock units excluded from the computation of diluted earnings per share was 1,164 and 1,055, respectively, because their effect was antidilutive. Diluted earnings per share-weighted average shares outstanding do not include any effect resulting from assumed conversion of the Notes and warrants as their impact would be anti-dilutive.

The Company’s basic and diluted earnings per share amounts are as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2013		2012		2013		2012

Critical Accounting Policies

The preparation of condensed consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make judgments, assumptions and estimates that affect the amounts reported. Certain of these significant accounting policies are considered to be critical accounting policies, as defined below.

A critical accounting policy is defined as one that is both material to the presentation of our condensed consolidated financial statements and requires management to make difficult, subjective or complex judgments that could have a material effect on our financial condition or results of operations. Specifically, these policies have the following attributes: (1) we are required to make judgments and assumptions about matters that are highly uncertain at the time of the estimate; and (2) different estimates we could reasonably have used, or changes in the estimate that are reasonably likely to occur, could have a material effect on our financial position and results of operations.

Estimates and assumptions about future events and their effects cannot be determined with certainty. We base our estimates on historical experience and on various other assumptions believed to be applicable and reasonable under the circumstances. These estimates may change as new events occur, as additional information is obtained and as our operating environment changes. These changes have been included in the condensed consolidated financial statements as soon as they became known. In addition, management is periodically faced with uncertainties, the outcomes of which are not within its control and will not be known for prolonged periods of time. Certain of these uncertainties are discussed in our 2012 Annual Report on Form 10-K in the sections entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Based

18

on a critical assessment of our accounting policies and the underlying judgments and uncertainties affecting the application of those policies, management believes that our condensed consolidated financial statements are fairly stated in accordance with accounting principles generally accepted in the United States of America, and provide a fair presentation of our financial position and results of operations.

For more information, please see our critical accounting policies as previously disclosed in our 2012 Annual Report on Form 10-K.

See Note 1 to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q regarding the impact of recent accounting pronouncements on our financial position and results of operations.

Results of Operations for the Three and Nine Month Periods EndedSeptember 30, 2013 and 2012

We are a worldwide leader in the design, development, manufacture and support of defect inspection, advanced packaging lithography, process control metrology, and data analysis systems and software used by microelectronic device manufacturers. We provide process and yield management solutions used in both wafer processing and final manufacturing through a family of standalone systems for macro-defect inspection, lithography, probe card test and analysis, and transparent and opaque thin film measurements. All Rudolph systems feature sophisticated software and production-worthy automation. Rudolph systems are backed by worldwide customer support.

Rudolph’s business is affected by the annual spending patterns of our customers on semiconductor capital equipment. The amount that our customers devote to capital equipment spending depends on a number of factors, including general worldwide economic conditions as well as other economic drivers such as personal computer, tablet, cell phone, other personal electronic devices and automotive sales. Current forecasts by industry analysts for the semiconductor device manufacturing industry project a year-over-year increase in capital spending of approximately 15% for 2014. We monitor capital equipment spending through announced capital spending plans by our customers and monthly-published industry data such as the book-to-bill ratio. The book-to-bill ratio is a 3-month running statistic that compares bookings or orders placed with capital equipment suppliers to billings or shipments. A book-to-bill above 1.0 shows that semiconductor device equipment manufacturers are ordering equipment at a pace that exceeds the equipment suppliers’ shipments for the period. The 3-month rolling average North American semiconductor equipment book-to-bill ratio was 1.0 at September 30, 2013, an increase from the book-to-bill ratio of 0.9 at December 31, 2012.

Historically, a significant portion of our revenues in each quarter and year has been derived from sales to relatively few customers, and we expect this trend to continue. For the nine month period ended September 30, 2013 and for the years ended December 31, 2012, 2011 and 2010, sales to customers that individually represented at least five percent of our revenues accounted for 41.1%, 50.9%, 43.6%, and 44.4% of our revenues, respectively.

We do not have purchase contracts with any of our customers that obligate them to continue to purchase our products, and they could cease purchasing products from us at any time. A delay in purchase or cancellation by any of our large customers could cause quarterly revenues to vary significantly. In addition, during a given quarter, a significant portion of our revenues may be derived from the sale of a relatively small number of systems. Our macro-defect inspection and probe card and test analysis systems range in average selling price from approximately $250,000 to $1.7 million per system; our transparent film measurement systems range in average selling price from approximately $800,000 to $1.2 million per system; our opaque film measurement systems range in average selling price from approximately $1.0 million to $1.8 million per system; and our lithography steppers range in average selling price from approximately $3.0 million to $4.0 million per system.

A significant portion of our revenues has been derived from customers outside of the United States.  We expect that revenues generated from customers outside of the United States will continue to account for a significant percentage of our revenues. 

The following table lists, for the periods indicated, the revenue derived from customers outside of the United States (in percentages of total revenues): 

	Nine Months Ended
	September 30,		Years Ended December 31,
	2013		2012		2011		2010
Asia	62.4	%	67.3	%	51.3	%	65.7	%
Europe	12.6	%	13.4	%	20.4	%	11.1	%
Total international revenue	75.0	%	80.7	%	71.7	%	76.8	%

The sales cycle for our systems typically ranges from six to 15 months, and can be longer when our customers are evaluating new technology. Due to the length of these cycles, we invest significantly in research and development and sales and marketing in advance of generating revenues related to these investments.

19

Revenues. Our revenues are primarily derived from the sale of our systems, services, spare parts and software licensing.  Our revenue was $44.0 million and $131.8 million for the three and nine month periods ended September 30, 2013, compared to $62.2 million and $164.2 million for the three and nine month periods ended September 30, 2012, representing decreases of 29.1% and 19.8% in the year-over-year periods. 

The following table lists, for the periods indicated, the different sources of our revenues in dollars (thousands) and as percentages of our total revenues:

	Three Months Ended								Nine Months Ended
	September 30,								September 30,

Total systems and software revenue decreased for the nine months ended September 30, 2013 compared to the nine month period ended September 30, 2012 due to decreased customer demand for our inspection and metrology systems as well as our software products. The decrease in customer demand for our products compared to the prior year period is due to a slowdown in capital equipment purchases by semiconductor manufacturers. This decrease in customer demand contributed to a lower number of inspection systems sold during the nine months ended September 30, 2013 as compared to the same period in the prior year. As a result, inspection systems revenue decreased $25.8 million for the 2013 period compared to the 2012 period. The number of metrology systems sold during the nine months ended September 30, 2013 was impacted by lower customer demand from the same period in the prior year, resulting in a decrease in metrology systems revenue of $14.3 million for the 2013 period. The year-over-year increase in lithography system revenue for the nine months ended September 30, 2013 of $7.3 million is due to our entrance into the lithography market during the 2013 period. The year-over-year decrease in data analysis and review software revenue for the nine months ended September 30, 2013 of $1.5 million is primarily due to decreased sales in licensing and consulting revenue.  As a result, the decrease in revenue for the 2013 period was caused by decreased volume rather than pricing changes as the average selling price of similarly configured systems has been consistent across the year-over-year periods. Systems revenue generated by our latest product releases and major enhancements in each of our product families amounted to 58% and 64% of total revenues for the three and nine month periods ended September 30, 2013, compared to 73% and 68% of total revenues for the three and nine month periods ended September 30, 2012.  The year-over-year increase in total parts and services revenue for the three and nine month periods ended September 30, 2013 is primarily due to increased spending by our customers on system upgrades and repairs of existing systems. Parts and services revenues are generated from part sales, maintenance service contracts, system upgrades, as well as time and material billable service calls. 

Deferred revenues of $8.0 million are recorded in the Condensed Consolidated Balance Sheets within the caption “Other current liabilities” at September 30, 2013 and primarily consist of $2.2 million for systems awaiting acceptance and outstanding deliverables and $5.8 million for deferred maintenance agreements.

Gross Profit. Our gross profit has been and will continue to be affected by a variety of factors, including manufacturing efficiencies, excess and obsolete inventory write-offs, pricing by competitors or suppliers, new product introductions, production volume, customization and reconfiguration of systems, international and domestic sales mix, and parts and service margins. Our gross profit was $22.5 million and $67.9 million for the three and nine month periods ended September 30, 2013, compared to $33.1 million and $87.1 million for the three and nine month periods ended September 30, 2012.  Our gross profit represented 51.0% and 51.5% of our revenues for the three and nine month periods ended September 30, 2013 and 53.3% and 53.1% of our revenues for the same periods in the prior year.  The decrease in gross profit as a percentage of revenue for the three and nine month periods ended September 30, 2013 compared to the same period in the prior year is primarily due to product mix and lower system sales volume.

Operating Expenses. Major components of operating expenses include research and development as well as selling, general and administrative expenses. 

Research and Development.  Our research and development expense was $10.5 million and $30.4 million for the three and nine month periods ended September 30, 2013, compared to $10.2 million and $29.4 million for the same

20

periods in the prior year.  Research and development expense represented 23.7% and 23.1% of our revenues for the three and nine month periods ended September 30, 2013, compared to 16.5% and 17.9% of revenues for the prior year periods.  The year-over-year dollar increase for the three and nine month periods ended September 30, 2013 in research and development expenses primarily reflects the inclusion of research and development expenses generated at NanoPhotonics and Azores, which were acquired during the latter part of 2012, and our acquisition in the 2013 second quarter of Tamar Technology.

Selling, General and Administrative.     Our selling, general and administrative expense was $10.1 million and $30.8 million for the three and nine month periods ended September 30, 2013, compared to $10.3 million and $29.4 million for the same periods in the prior year.  Selling, general and administrative expense represented 22.8% and 23.4% of our revenues for the three and nine month periods ended September 30, 2013, compared to 16.6% and 17.9% of our revenues for the same periods in the prior year.  The year-over-year dollar increase for the three and nine month periods ended September 30, 2013 in selling, general and administrative expense was primarily due to the inclusion of selling, general and administrative expenses generated at NanoPhotonics and Azores, which were acquired in the latter part of 2012, and our acquisition in the 2013 second quarter of Tamar Technology.

Income Taxes.  For the three and nine month periods ended September 30, 2013, we recorded an income tax benefit of $0.2 million and $0.3 million, respectively, as compared to tax provisions of $3.9 million and $8.5 million for the same periods in the prior year. Our effective tax rate of (581.1)% differs from the statutory rate of 35% for the three months endedSeptember 30, 2013 primarily due to the impact of tax credits on lower projected income for 2013. Our effective tax rate of (26.0)% differs from the statutory rate of 35% for the nine months endedSeptember 30, 2013 primarily due to recording a discrete event for research and development tax credit for 2012. The American Taxpayer Relief Act of 2012 was passed by Congress and signed into law in January 2013. The provisions under this law were made retroactive to January 1, 2012. However, as a result of the law being signed in January 2013, the financial impact of any retroactive provision was recorded as a discrete item in the tax provision in the first quarter of 2013. Our effective tax rate approximates the statutory tax rate of 35% for the three and nine month periods ended September 30, 2012.

We currently have a partial valuation allowance recorded against our deferred tax assets. Each quarter we assess the likelihood that we will be able to recover our deferred tax assets primarily relating to state R&D credits. We consider available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance. As a result of our analysis, we concluded that it is more likely than not that a portion of our net deferred tax assets will not be realized. Therefore, we continue to provide a valuation allowance against certain net deferred tax assets. We continue to closely monitor available evidence and may reverse some or all of the valuation allowance in future periods, if appropriate.

Litigation. As discussed in Part II, Item 1 of this Quarterly Report on Form 10-Q (“Legal Proceedings”), we are subject to legal proceedings and claims, which includes, among other things, our on-going litigation with ITC in a patent infringement action related to the predictive scrub feature of our PrecisionPoint^™, PrecisionWoRx^® and ProbeWoRx^® products in which we were the defendants. See Part II, Item 1 of this Quarterly Report on Form 10-Q (“Legal Proceedings”) for a discussion of this action and the District Court’s adverse order affirming the jury award and ordering other relief in this matter and the ruling obtained from the U.S. Federal Court of Appeals. In the event that the ultimate decision in the ITC Litigation results in a judgment of damages against us at the high end of the identified ranges, such result will have a material impact on our results of operations and may also have a material impact on our liquidity and financial condition.

Liquidity and Capital Resources

At September 30, 2013, we had $158.6 million of cash, cash equivalents and marketable securities and $256.4 million in working capital.  At December 31, 2012, we had $169.2 million of cash, cash equivalents and marketable securities and $251.5 million in working capital. 

Operating activities used $4.0 million in cash and cash equivalents for the nine month period ended September 30, 2013.  The net cash and cash equivalents used in operating activities during the nine month period ended September 30, 2013 was primarily a result of an increase in inventory of $10.6 million, a decrease in other current liabilities of $4.5 million, an increase in prepaid expenses and other assets of $3.0 million and an increase in accounts receivable of $1.9 million, partially offset by an increase in accounts payable and accrued liabilities of $1.7 million, and net income adjusted to exclude the effect of non-cash operating charges of $14.2 million. Operating activities provided $15.8 million in cash and cash equivalents for the nine month period ended September 30, 2012. The net cash and cash equivalents provided by operating activities during the nine month period ended September 30, 2012 was primarily a result of net income, adjusted to exclude the effect of non-cash operating charges of $27.0 million, an increase in accounts payable and accrued liabilities of $11.6 million, and an increase in other current liabilities of $11.3 million, partially offset by an increase in accounts receivable of $19.8 million, an increase in inventory of $9.8 million, and an increase prepaid expenses and other assets of $4.7 million.

21

Net cash and cash equivalents used in investing activities during the nine month period ended September 30, 2013 of $17.4 million was due to the purchase of marketable securities of $81.7 million, capital expenditures of $4.0 million, and purchase of business of $3.4 million, partially offset by the proceeds from sales of marketable securities of $71.7 million.  Net cash and cash equivalents used in investing activities during the nine month period ended September 30, 2012 of $6.6 million was due to the purchase of marketable securities of $70.6 million, the purchase of business of $7.9 million, and capital expenditures of $1.3 million, partially offset by the proceeds from sales of marketable securities of $73.2 million.

In July 2008, our Board of Directors approved a stock repurchase program of up to 3 million shares of Company common stock with no established end date.  As of the time of filing this Quarterly Report on Form 10-Q, we have not purchased any shares under this program.

From time to time, we evaluate whether to acquire new or complementary businesses, products and/or technologies. We may fund all or a portion of the purchase price of these acquisitions in cash, stock, or a combination of cash and stock.

As of September 30, 2013, we had a $40 million irrevocable standby letter of credit available with Credit Suisse AG which is required to secure the damages assessment in connection with the ITC litigation discussed in Part II, Item 1 in this Quarterly Report on Form 10-Q (“Legal Proceedings”). The letter of credit expires on February 25, 2014 with provisions for automatic renewal. Upon draw down of funds, the letter of credit would be collateralized by securities held in our investment portfolios and reported in the Condensed Consolidated Balance Sheets within the caption “Cash and cash equivalents” and “Marketable securities.” No amounts were outstanding on the letter of credit as of, or during the three and nine months ended, September 30, 2013.

Our future capital requirements will depend on many factors, including the timing and amount of our revenues and our investment decisions, which will affect our ability to generate additional cash. We believe that our existing cash, cash equivalents and marketable securities will be sufficient to meet our anticipated cash requirements for working capital and capital expenditures for the next twelve months. Thereafter, if cash generated from operations and financing activities is insufficient to satisfy our working capital requirements, we may seek additional funding through bank borrowings, sales of securities or other means. There can be no assurance that we will be able to raise any such capital on terms acceptable to us or at all.

Item 3.    Quantitative and Qualitative Disclosures about Market Risk

Interest Rate and Credit Market Risk

We are exposed to changes in interest rates and market liquidity including our investments in certain available-for-sale securities. Our available-for-sale securities consist of fixed and variable rate income investments (municipal notes, municipal and corporate bonds and an auction rate security). We continually monitor our exposure to changes in interest rates, market liquidity and credit ratings of issuers from our available-for-sale securities. It is possible that we are at risk if interest rates, market liquidity or credit ratings of issuers change in an unfavorable direction. The magnitude of any gain or loss will be a function of the difference between the fixed or variable rate of the financial instrument and the market rate and our financial condition and results of operations could be materially affected. Based on a sensitivity analysis performed on our financial investments held as of September 30, 2013, an immediate adverse change of 10% in interest rates (e.g. 3.00% to 3.30%) would result in an immaterial decrease in the fair value of our available-for-sale securities and would not have a material impact on our consolidated financial position, results of operations or cash flows.

Foreign Currency Risk

We have branch operations in Taiwan, Singapore and South Korea and wholly-owned subsidiaries in Europe, China and Japan.  Our international subsidiaries and branches operate primarily using local functional currencies.  The intercompany transactions denominated in U.S. dollars appearing on the financial statements of the subsidiaries and branches are remeasured at each quarter-end resulting in gains and losses which are reflected in net income.  A hypothetical 10% appreciation or depreciation in the U.S. dollar relative to the reporting currencies of our foreign subsidiaries at September 30, 2013 would have affected the foreign-currency-denominated non-operating expenses of our foreign subsidiaries by approximately $0.2 million. We cannot accurately predict future exchange rates or the overall impact of future exchange rate fluctuations on our business, results of operations and financial condition.

A substantial portion of our international sales are denominated in U.S. dollars with the exception of Japan and, as a result, we have relatively little exposure to foreign currency exchange risk with respect to these sales. Substantially all our sales in Japan are denominated in Japanese yen. From time to time, we may enter into forward exchange contracts to economically hedge a portion of, but not all, existing and anticipated foreign currency denominated transactions expected to occur within 12 months. The change in fair value of the forward contracts is recognized in Other expense (income) in the Condensed Consolidated Statements of Operations each reporting period. As of September 30, 2013, we had three forward contracts outstanding with a total notional contract value of $0.5 million. We do not use derivative financial instruments for trading or speculative purposes.

22

Item 4.  Controls and Procedures

We maintain a set of disclosure controls and procedures, as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Exchange Act, designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow for timely decisions regarding required disclosure. The disclosure controls and procedures are designed to provide reasonable assurance of achieving the desired control objectives. 

Scope of the Controls Evaluation

The evaluation of our disclosure controls and procedures included a review of the controls’ objectives and design, our implementation of the controls and the effect of the controls on the information generated for use in this Quarterly Report on Form 10-Q. In the course of the evaluation, we sought to identify data errors, control problems or acts of fraud and confirm that appropriate corrective actions, if any, including process improvements, were being undertaken. This type of evaluation is performed on a quarterly basis so that the conclusions of management, including the CEO and CFO, concerning the effectiveness of the controls can be reported in our Quarterly Reports on Form 10-Q and in our Annual Reports on Form 10-K. Many of the components of our disclosure controls and procedures are also evaluated on an ongoing basis by other personnel in our accounting, finance and legal functions. The overall goals of these various evaluation activities are to monitor our disclosure controls and procedures and to modify them on an ongoing basis as necessary. A control system can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

Conclusions

As of September 30, 2013, an evaluation of our disclosure controls and procedures was carried out under the supervision and with the participation of our management, including the CEO and CFO. Based on this evaluation, the CEO and CFO have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of the end of the period covered by this Quarterly Report on Form 10-Q.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting that occurred during the period covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II    OTHER INFORMATION

Item 1.   Legal Proceedings

From time to time, we are subject to legal proceedings and claims in the ordinary course of business. As previously disclosed, in December 2007, we completed the acquisition of specific assets and liabilities of the semiconductor division of Applied Precision LLC (“Applied”). As a result of the acquisition, we assumed certain liabilities of Applied including a lawsuit filed in the United States District Court, District of Arizona, by Integrated Technology Corporation (“ITC”) which alleged Applied’s PrecisionPoint^™, PrecisionWoRx^® and ProbeWoRx^® products infringed an ITC patent (Integrated Technology Corporation v. Rudolph Technologies, Inc., No. CV-06-2182-PHX-ROS). Prior to trial, the District Court ruled that such products soldprior to August of 2007 infringed the ITC patent. In December 2011, a trial verdict was rendered in which the jury found that while our products manufactured after August of 2007 did not literally infringe ITC’s patent, the products were found to infringe under a rule known as the doctrine of equivalents, a legal principle which expands the scope of patent claims to encompass products or processes which may otherwise be found not to literally infringe the patent. The jury awarded $15.5 million to ITC in damages for sales made during the years 2000-2011, of which award approximately one-half related to sales made after August 2007. The jury found that for sales made after August of 2007 the infringement was willful. On July 23, 2012, the District Court, responding to post-trial motions filed by us and ITC related to the verdict and damages assessment, issued an Order which affirmed the jury’s award, applied treble damages to the portion of the jury award related to sales of the products after 2007 and granted ITC’s motion for attorney’s fees and prejudgment interest on the verdict and attorney’s fees. The District Court also enjoined us from future infringement of the ITC patent and from selling or supplying the applicable products with the applicable features from or into the United States. We appealed the injunction as well as the District Court Order and the damages assessment. In October 2012, the

23

injunction was stayed by the Federal Court of Appeals.  In November 2013, the U.S. Federal Court of Appeals issued a ruling reversing the findings of infringement under the doctrine of equivalents and willfulness regarding the post-August 2007 products, vacating the damages awards regarding these products.  In addition, the Appeals Court vacated the award of attorney’s fees and remanded the matter to the District Court to reassess its findings on this issue in the absence of willfulness.  Finally, the Appeals Court affirmed the damages assessed against the pre-August 2007 products.  We are currently assessing our options regarding this final ruling as we believe that our position on the pre-2007 damages is meritorious defenses and shall continue to vigorously pursue this matter.  With the Appeals Court ruling, our post-August 2007 products have been found to not have infringed ITC’s patent, literally or under the doctrine of equivalents, so therefore no damages are assessed against us for these products.  With regard to products sold before August of 2007, it is probable that we could realize a loss in this matter for which we have estimated and recorded a liability of approximately $4.3 million in “Other liabilities” in the Consolidated Balance Sheets. The maximum liability reasonably possible for the pre-August 2007 products is an additional $3.4 million plus interest beyond the accrual. While we continue to believe that our current PrecisionWoRx® and ProbeWoRx® systems do not infringe ITC’s patent, we reached an agreement with ITC in October 2012 with regards to a redesign of the products under which ITC agreed that such redesign is permissible under the court’s injunction.

In our patent infringement suit against Camtek, Ltd., of Migdal Hamek, Israel, concerning our proprietary continuous scan wafer inspection technology, the U.S. Federal Court of Appeals issued a ruling on August 22, 2011.  In its opinion, the Appellate Court affirmed multiple rulings from trial at the District Court level including (i) finding our U.S. Patent No. 6,826,298 valid, (ii) the part of the infringement ruling based on the finding that Camtek’s Falcon product strobes “based on velocity,” and (iii) the dismissal of Camtek’s claim against us for inequitable conduct against the U.S. Patent and Trademark Office.  The court did, however, revise one claim construction ruling made by the District Court in the original case.  As a result, the Appellate Court set aside the verdict delivered by the jury for damages and the District Court’s decision to enter an injunction against Camtek’s selling Falcon tools in the U.S. and remanded the case back to the trial court for a limited trial on this single infringement issue.  No trial date has been set for this limited trial.  This lawsuit was initially brought in 2005 by August Technology prior to its merger with us.

Item 1A.    Risk Factors

There were no material changes to our risk factors as discussed in Part I, Item 1A - Risk Factors in our 2012 Annual Report on Form 10-K.

Item 2.    Unregistered Sales of Equity Securities and Use of Proceeds

In July 2008, our Board of Directors authorized a share repurchase program of up to 3 million shares of the Company’s common stock with no established end date. As of the time of filing this Quarterly Report on Form 10-Q, we have not purchased any shares under this program.

Marketable Securities [Abstract]

Marketable Securities [Text Block]

Marketable Securities

The Company has evaluated its investment policies and determined that all of its investment securities are to be classified as available-for-sale.  Available-for-sale securities are carried at fair value, with the unrealized gains and losses reported in Stockholders’ Equity under the caption “Accumulated other comprehensive loss.”  Realized gains and losses on available-for-sale securities are included in “Other expense (income)” in the Condensed Consolidated Statements of Operations.  The Company records other-than-temporary impairment charges for its available-for-sale investments when it intends to sell the securities, it is more-likely-than not that it will be required to sell the securities before a recovery, or when it does not expect to recover the entire amortized cost basis of the securities.  The cost of securities sold is based on the specific identification method.

As of September 30, 2013, the Company held one auction rate security with a fair value of $291. The underlying asset of the Company’s auction rate security consisted of a municipal bond with an auction reset feature. Due to auction failures in the marketplace, the Company will not have access to these funds unless (a) future auctions occur and are successful, (b) the security is called by the issuer, (c) the Company sells the security in an available secondary market, or (d) the underlying note matures. Currently, there are no active secondary markets. As of September 30, 2013, the Company had recorded a cumulative temporary unrealized impairment loss of $184 within “Accumulated other comprehensive loss” based upon its assessment of the fair value of this security. The Company believes that this impairment is temporary, as it does not intend to sell this security, the Company will not be required to sell this security before recovery, and the Company expects to recover the amortized cost basis of this security.

The Company has determined that the gross unrealized losses on its marketable securities at September 30, 2013 and December 31, 2012 are temporary in nature. The Company reviews its investment portfolio to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the cost basis, credit quality and the Company’s ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value.

At September 30, 2013 and December 31, 2012, marketable securities are categorized as follows:

	Amortized Cost		Gross Unrealized Holding Gains		Gross Unrealized Holding Losses			Fair Value
September 30, 2013
Municipal notes and bonds	$	73,975	$	47	$	(3	)	$	74,019

 The amortized cost and estimated fair value of marketable securities classified by the maturity date listed on the security, regardless of the Condensed Consolidated Balance Sheet classification, is as follows at September 30, 2013 and December 31, 2012:

	September 30, 2013				December 31, 2012

The following table summarizes the estimated fair value and gross unrealized holding losses of marketable securities, aggregated by investment instrument and period of time in an unrealized loss position at September 30, 2013 and December 31, 2012:

Income Taxes

The following table provides details of income taxes:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2013			2012			2013			2012
Income before income taxes	$	37		$	10,571		$	1,114		$	23,375
Provision (benefit) for income taxes	$	(215	)	$	3,910		$	(290	)	$	8,506
Effective tax rate	(581.1		)%	37.0		%	(26.0		)%	36.4		%

The income tax provision for the three and nine months endedSeptember 30, 2013 was computed based on the Company’s annual forecast of profit by jurisdiction and forecasted effective tax rate for the year. The changes in the Company’s effective tax rate for the nine months endedSeptember 30, 2013 compared to the same period for the prior year are primarily due to anticipated generation of federal R&D credits for both 2012 and 2013 recognized in 2013, which were not available in the 2012 period as a result of legislation. The changes in the effective tax rate for the three months endedSeptember 30, 2013 compared to the same period for the prior year are primarily due to the impact of tax credits and lower annual profit projections.

The Company currently has a partial valuation allowance recorded against certain deferred tax assets. Each quarter, the Company assesses the likelihood that it will be able to recover its deferred tax assets. The Company considers available evidence, both positive and negative, including prudent and feasible tax planning strategies in assessing the need for a valuation allowance. As a result of the Company’s analysis, it concluded that it is more likely than not that a portion of its deferred tax assets will not be realized. Therefore, the Company continues to provide a valuation allowance against certain deferred tax assets. The Company continues to closely monitor available evidence and may reverse some or all of the remaining valuation allowance in future periods, if appropriate. The Company has a valuation allowance of $1,361 as of September 30, 2013 and December 31, 2012.

In the normal course of business, the Company is subject to examination by taxing authorities throughout the world. The Company is currently under a federal income tax examination by the Internal Revenue Service for the tax years ended December 31, 2007 through December 31, 2009. In addition, the Company is under examination by the State of New York for the tax years 2009 through 2011. The Company has not been contacted by any other U.S. state, local or foreign tax authority for all open tax periods beginning after December 31, 2007.

Business Combinations

Tamar Technology

In April 2013, the Company announced that it had acquired specific assets of Tamar Technology, located in Newbury Park, California (Tamar acquisition). The Company paid $3,365 of the purchase price in cash and accrued an additional $6,198 for contingent consideration. The acquired business has been integrated into the Company’s inspection technology group.  The impact of the acquisition was not material to the Company’s consolidated financial position or results of operations.

Azores

In December 2012, the Company announced that it had acquired Azores Corporation, located in Wilmington, Massachusetts (Azores acquisition). The acquired business marks the Company's entry into the advanced packaging and flat panel display lithography markets and forms the Company’s lithography systems group. The impact of the acquisition was not material to the Company’s consolidated financial position or results of operations.

The Company made a preliminary allocation of the purchase price to the assets acquired and liabilities assumed as of the acquisition date for the Azores acquisition and the Tamar acquisition. For the period ended September 30, 2013, the Company finalized the purchase price allocation for Azores, with the exception of taxes, and recorded adjustments to goodwill and inventory. The Company recast its December 31, 2012 balance sheet to reflect these adjustments. The Company will finalize its analysis of the remaining purchase price allocation within the measurement period, not to exceed one year from the date of the acquisition, and therefore additional adjustments may occur.

Derivative Instruments and Hedging Activities

The Company, when it considers it to be appropriate, enters into forward contracts to hedge the economic exposures arising from foreign currency denominated transactions. At September 30, 2013 and December 31, 2012, these contracts included the future sale of Japanese Yen to purchase U.S. dollars. Derivative instruments are recognized as either “Prepaid expenses and other current assets” or “Other current liabilities” in the Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Cash Flows and are measured at fair value. The foreign currency forward contracts were entered into by the Company’s Japanese subsidiary to economically hedge a portion of certain intercompany obligations. The forward contracts are not designated as hedges for accounting purposes and therefore, decreases in the fair value of $259 and $241 for the nine month periods ended September 30, 2013 and 2012, respectively, are recorded within the caption “Other expense (income)” in the Condensed Consolidated Statements of Operations.

The dollar equivalent of the U.S. dollar forward contracts and related fair values as of September 30, 2013 and December 31, 2012 were as follows:

	September 30, 2013		December 31, 2012

Fair Value Measurements

Fair Value Measurements [Abstract]

Fair Value Disclosures [Text Block]

Fair Value Measurements

The Company applies a three-level valuation hierarchy for fair value measurements. This hierarchy prioritizes the inputs into three broad levels.  Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability. Level 3 inputs are unobservable inputs based on management’s assumptions used to measure assets and liabilities at fair value. A financial asset’s or liability’s fair value measurement classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following tables provide the assets and liabilities carried at fair value measured on a recurring basis at September 30, 2013 and December 31, 2012:

			Fair Value Measurements Using
	Carrying Value		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Foreign currency forward contracts	268		—		268		—
Total Assets	$	65,231	$	—	$	64,885	$	346

Level 1 investments are based on quoted prices that are available in active markets.

The Company’s investments classified as Level 2 are valued using observable inputs to quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. The foreign currency forward contracts are primarily measured based on the foreign currency spot and forward rates quoted by the banks or foreign currency dealers. Available-for-sale debt securities prices are obtained from third party pricing providers, which models prices utilizing the above observable inputs, for each asset class.

Level 3 investments consist of an auction rate security and contingent consideration related to an acquisition for which the Company uses a discounted cash flow model to value these investments. The Level 3 assumptions used in the discounted cash flow model for the auction rate security included estimates of interest rates of 3.4%, timing of cash flows and expected holding periods. Changes in the unobservable input values would be unlikely to cause material changes in the fair value of the auction rate security. The Level 3 assumptions used in the discounted cash flow model for the contingent consideration included projected revenues, estimates of discount rates and timing of cash flows. A significant decrease in the projected revenues could result in a significantly lower fair value measurement for the contingent consideration.

This table presents a reconciliation for all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the nine months endedSeptember 30, 2013:

	Fair Value Measurements Using Significant Unobservable Inputs (Level 3)
Assets:
Balance at December 31, 2012	$	346

Sales, issuances, and settlements	—

See Note 4 for additional discussion regarding the fair value of the Company’s marketable securities.

Fair Value of Other Financial Instruments

The carrying value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates fair value because of the short maturity of these instruments. The estimated fair value of these obligations is based, primarily, on a market approach, comparing the Company’s interest rates to those rates the Company believes it would reasonably receive upon re-entry into the market.
