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. |

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. |

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: | |||||||||||||||||

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. | |||||||||||||||||

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 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. | |||||||||||||||||

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. | ||||||||

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. | ||||||||||||||||

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. | |||||||||

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 sold prior 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 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 sold before 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. |

The income tax provision for the three and nine months ended September 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 ended September 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 ended September 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. |

Earnings Per Share | ||||||||||||||||
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 ended September 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 ended September 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. | ||||||||||||||||
