<div> <div> 2. Acquisitions CardioSpectra Acquisition On December 18, 2007, we acquired CardioSpectra, Inc., or CardioSpectra, a privately held corporation, for an aggregate purchase price of $27.0 million. The acquisition of CardioSpectra's OCT technology is expected to complement our existing product offerings and further enhance our position as an imaging technology leader in the field of interventional medicine. The acquisition was accounted for as an asset purchase. We have included the operating results associated with the CardioSpectra acquisition in our consolidated financial statements from the date of acquisition. Subject to the terms of the Merger Agreement, we may be required to make milestone payments. The milestone payments are payable, at our sole discretion, in cash, shares of our common stock, or a combination of both and will be accounted for if and when the milestone payments become payable. We have used and will continue to use commercially reasonable efforts to cause the milestones to occur. However, if we reasonably determine that a technical failure or commercial failure has occurred with respect to all or a part of the OCT program, we may, at our sole discretion, terminate all or part of the OCT cardiovascular program.   In December 2009, the first milestone specified in the CardioSpectra merger agreement was achieved and at December 31, 2009, the corresponding milestone payment totaling $11.0 million was recorded as in-process research and development, or IPR&D, expense. In January 2010, we paid the milestone payment with the issuance of 609,360 shares of our common stock and $531,000 of cash. The second milestone specified in the merger agreement was not achieved as of December 31, 2010, and as such, the second milestone payment was not paid and no IPR&D was recorded. Additional remaining milestone payments of up to $17.0 million may be paid upon achievement of the respective revenue targets described in the merger agreement. As of December 31, 2011, we have not achieved the respective revenue targets. Therefore, we have not recorded any liability related to these milestones. Novelis Acquisition On May 15, 2008, we acquired all of the outstanding equity interests in Novelis, Inc., or Novelis, a privately-held company, which developed proprietary ultrasonic visualization and therapy technology for minimally invasive diagnostic and therapeutic devices. The core product line of Novelis is based on FL.IVUS technology. The aggregate purchase price was $12.3 million including transaction costs. The acquisition was accounted for as an asset purchase. We have included the operating results associated with the Novelis acquisition in our consolidated financial statements from the date of acquisition. Under the terms of the merger agreement, a milestone payment of $3.0 million was eligible to be earned by the Novelis stockholders upon receipt of FDA approval of the original 510(k) application relating to the Novelis FL.IVUS device, but only in the event that the original 510(k) application for such a device was filed with the FDA on or before December 31, 2009. At December 31, 2009 a 510(k) application had been made to the FDA. At that time, we believed that the 510(k) application would be approved and that the milestone would become payable. Accordingly, at December 31, 2009 we recorded an accrual for $3.0 million in relation to the potential milestone payment. Based on our internal assessments in relation to our ongoing interactions with the FDA regarding this 510(k) application, during the fourth quarter of 2010 it became apparent that our 510(k) application would not be approved prior to its expiration. Accordingly, we reversed the accrual for the milestone payment, resulting in a $3.0 million credit to IPR&D expense during the fourth quarter of 2010. Axsun Acquisition On December 24, 2008, we acquired all of the outstanding equity interests in Axsun, a privately-held company that develops and manufactures optical monitors for the telecommunications industry, laser and non-laser light sources and optical engines used in OCT imaging systems and advanced photonic components and subsystems used in spectroscopy and other industrial applications. The aggregate purchase price of $23.8 million consisted of $22.3 million paid in cash, assumed liabilities of $6.5 million, and transaction costs of $725,000, net of cash received of $5.8 million. The acquisition was accounted for as a business combination. We have included the operating results associated with the Axsun acquisition in our consolidated financial statements from the date of acquisition. Fluid Medical Acquisition On August 5, 2010, we acquired all of the outstanding equity interests in Fluid Medical, Inc., or Fluid Medical, a privately-held company, which is engaged in the development of imaging technology for use in various structural heart applications, including, but not limited to, mitral valve repair. Fluid Medical's technology and intellectual property provide forward field of view imaging on highly maneuverable catheters that have the potential to enable or enhance visualization for procedures currently done with inadequate imaging. This technology is expected to result in a Forward-Looking Intra-Cardiac Echo, or FL.ICE catheter that will initially be focused on minimally invasive structural heart applications, such as percutaneous aortic and mitral valve therapies.   The purchase price of $4.2 million consisted of $3.6 million in cash payments and $150,000 of debt forgiveness related to working capital loans we made to Fluid Medical prior to the acquisition. We retained $400,000 as a "hold-back" liability to satisfy any claims for indemnification made within 18 months following the closing, the majority of which was released in February 2012. The transaction was accounted for as a business combination and, as such we recorded $1.6 million of goodwill reflecting the amount by which the purchase consideration exceeded the acquired net assets. This goodwill was allocated to our medical segment and is not deductible for income tax purposes. We recorded $184,000 of acquisition-related costs related to this transaction, which were recognized in our statement of operations for the year ended December 31, 2010 as selling, general and administrative expense. The purchase price allocation as of the acquisition date is summarized as follows (in thousands):   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="68%" align="center"> <tr><td width="84%"> </td> <td valign="bottom" width="11%"> </td> <td> </td> <td> </td> <td> </td></tr> <tr><td valign="bottom"> </td> <td valign="bottom">  </td> <td style="border-bottom: #000000 1px solid;" valign="bottom" colspan="2" align="center">August 5, 2010</td> <td valign="bottom"> </td></tr> <tr bgcolor="#cceeff"><td valign="top"> Current assets:</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td></tr> <tr><td valign="top"> Cash and cash equivalents</td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">46</td> <td valign="bottom" nowrap="nowrap">  </td></tr> <tr bgcolor="#cceeff"><td valign="top"> Property and equipment</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom" align="right">117</td> <td valign="bottom" nowrap="nowrap">  </td></tr> <tr><td valign="top"> In-process research and development</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom" align="right">4,050</td> <td valign="bottom" nowrap="nowrap">  </td></tr> <tr style="font-size: 1px;"><td valign="bottom"> </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td> </td></tr> <tr bgcolor="#cceeff"><td valign="top"> Total assets acquired</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom" align="right">4,213</td> <td valign="bottom" nowrap="nowrap">  </td></tr> <tr><td valign="top"> Current liabilities:</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td></tr> <tr bgcolor="#cceeff"><td valign="top"> Accrued compensation</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom" align="right">(22</td> <td valign="bottom" nowrap="nowrap">) </td></tr> <tr><td valign="top"> Other long-term liabilities</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom" align="right">(1,556</td> <td valign="bottom" nowrap="nowrap">) </td></tr> <tr style="font-size: 1px;"><td valign="bottom"> </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td> </td></tr> <tr bgcolor="#cceeff"><td valign="top"> Total liabilities acquired</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom" align="right">(1,578</td> <td valign="bottom" nowrap="nowrap">) </td></tr> <tr style="font-size: 1px;"><td valign="bottom"> </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td> </td></tr> <tr><td valign="top"> Net assets acquired</td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">2,635</td> <td valign="bottom" nowrap="nowrap">  </td></tr> <tr style="font-size: 1px;"><td valign="bottom"> </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td> </td></tr></table> The IPR&D asset we recorded represents an estimate of the fair value of in-process technology related to Fluid Medical's imaging technology program, which is still in the prototype phase. As such, pursuant to ASC 805, amortization of the IPR&D will not occur until it reaches market feasibility. Costs incurred in connection with this project subsequent to the date of acquisition will be expensed as incurred. In the event the project is abandoned, we will record an impairment charge for this amount. </div> </div>

<div> 4. Commitments and Contingencies Litigation—LightLab On January 7, 2009, LightLab Imaging, Inc., or LightLab, filed a complaint against us and our wholly owned subsidiary, Axsun, in the Superior Court of Massachusetts, Suffolk County, seeking injunctive relief and unspecified damages (the Massachusetts Action). LightLab develops and sells OCT products for cardiovascular imaging and other medical uses. On July 6, 2010, LightLab was acquired by St. Jude Medical, Inc., or St. Jude. Prior to our acquisition of Axsun, Axsun had entered into a development and supply agreement, or the Agreement, with LightLab, in which, among other things, Axsun agreed to supply tunable lasers to LightLab for use in LightLab's OCT imaging products until April 2016, with exclusivity in the field of coronary artery imaging expiring in April 2014. Since the acquisition, Axsun has continued to supply lasers to LightLab. The complaint includes allegations that Volcano interfered with the Agreement and with LightLab's advantageous business relationship with Axsun, that Axsun breached the Agreement, that Axsun and Volcano misappropriated LightLab's confidential information and trade secrets, and violated Chapter 93A, a Massachusetts statute that provides for recovery of up to three times damages plus attorneys fees (93A). The Judge ordered that the trial in the Massachusetts Action proceed in separate phases, with a jury trial first on liability, followed by a jury trial on damages, and then non-jury hearings on liability under 93A and on injunctive relief. The jury trial on liability commenced on January 4, 2010 and the jury returned a verdict on February 4, 2010 that included findings that the contract specifications for the lasers Axsun supplies and previously supplied to LightLab are trade secrets of LightLab, that Axsun agreed not to sell any tunable lasers to Volcano for any purpose or to third parties for use in cardiology imaging during the exclusivity period in the contract, and that Axsun breached its contract with LightLab. The jury further found that Volcano intentionally interfered with LightLab's advantageous business relationship with Axsun. A trial in the Massachusetts Action with respect to damages was set to commence on April 7, 2010, or Damages Trial. In lieu of conducting the Damages Trial, the parties agreed and stipulated that the sum of $200,000 would be treated as if it were the jury's verdict against the defendants in the Damages Trial (the Stipulation).   Upon the entry of the Stipulation, LightLab waived its rights, if any, to make any additional claims for special damages relating to lasers received in 2009 that do not meet the version 6 specification, for special damages claimed by LightLab in prior pleadings, and for the repair and/or replacement of any of the lasers specified in the Stipulation. In addition, Axsun waived its rights, if any, to make any claim for recovery from LightLab for certain engineering charges in connection with a development and supply agreement with LightLab, and for return by LightLab of any of the lasers specified in the Stipulation. Under the Stipulation, all parties expressly reserved their otherwise properly preserved rights of appeal. These rights include LightLab's appellate rights, if any, regarding its claim for alleged lost profits in excess of the above-referenced $200,000 stipulated amount to the extent LightLab is able to establish that it has properly preserved such rights. The injunctive relief phase of the Massachusetts Action commenced on April 12, 2010. In a ruling issued October 5, 2010, the Court rejected LightLab's claims for protection of five alleged trade secrets relating to laser technologies, and denied all of LightLab's requests for permanent injunctions with respect to those trade secrets. The ruling followed a two-week trial on five of a number of trade secret claims alleged by LightLab. In a summary judgment ruling issued January 26, 2011, the Court rejected the remainder of LightLab's claims for protection of its remaining trade secrets, and denied all of LightLab's claims for permanent injunctions with respect to those trade secrets. This judgment completed the trade secret portion of the Massachusetts Action. In a ruling issued January 28, 2011, the Court found that Volcano and Axsun violated 93A, and awarded LightLab additional damages of $400,000 and reasonable attorneys' fees. On February 10, 2011, and on April 7, 2011, the Court entered a Final Judgment and an Amended Final Judgment, respectively, in the Massachusetts Action: a) in favor of Volcano and Axsun on LightLab's claims for trade secret misappropriation on items 1-30 on LightLab's list of alleged trade secrets, b) ordered Volcano and Axsun to collectively pay $600,000 in damages (which amount includes the $200,000 agreed to in the Stipulation and the $400,000 ordered in the 93A ruling) and $4.5 million in attorneys' fees, (resulting in a total of $4.9 million recorded to selling, general and administrative expense and accrued in other current liabilities during the fourth quarter of 2010), c) in favor of LightLab on its claims against Axsun for breach of contract, breach of implied covenant of good faith and fair dealing, for violation of 93A, and misappropriation of trade secrets for disclosing three particular items to Volcano in December 2008 – the specifications for the two lasers provided by Axsun to LightLab and one Axsun laser prototype made in 2008, d) in favor of LightLab on its claims against Volcano for intentional interference with a contract and advantageous business relationship, unjust enrichment, violation of 93A, and misappropriation of trade secrets for the same three trade secrets described above. In addition, the Court denied a majority of LightLab's requested injunctions, and entered limited injunctive relief, none of which management believes have a material effect upon Volcano. The Final Judgment and Amended Final Judgment are substantially similar. The Amended Final Judgment corrects non-substantive clerical errors. On April 15, 2011, LightLab filed a notice of appeal, with respect to various decisions of the Court, including, a) the Court's decisions adverse to LightLab's claims for trade secret misappropriation in items 1-30 of LightLab's alleged list of trade secrets, including the Court's post-trial finding of fact and rulings of law adverse to LightLab on items 1 – 5, the Court's two summary judgment decisions adverse to LightLab on items 6 – 23 and 25 – 30 (item 24 having been voluntarily dismissed by LightLab), and various rulings requiring evidence of use or intent to use as a prerequisite for injunctive relief; b) the Court's post-trial decisions denying permanent injunctive relief that LightLab requested as terms of the Final Judgment; c) the Court's pre-trial rulings excluding certain lost profits damages evidence that LightLab sought to introduce at trial; d) various discovery and pre-trial orders denying LightLab discovery about Axsun's work for Volcano; e) the Court's order barring LightLab from claiming that the sale of Axsun to Volcano itself constituted a breach of the LightLab-Axsun supply contract; and f) the denial of LightLab's motion to alter or amend the Final Judgment, which motion sought to obtain additional declaratory relief barring Axsun from "supplying" tunable lasers to Volcano. Volcano and Axsun did not intend to cross appeal the Amended Final Judgment, and on July 5, 2011, Volcano and Axsun satisfied their payment obligations under the Amended Final Judgment by making a payment to Lightlab in the amount of approximately $5.4 million. On February 5, 2010, Volcano and our wholly owned subsidiary, Axsun, commenced an action in the Delaware Chancery Court (the Chancery Court Action), against LightLab seeking a declaration of Volcano and Axsun's rights with respect to certain OCT technology, the High Definition Swept Source. The complaint was served on LightLab on March 19, 2010. LightLab then filed a counter-claim that included a claim against Axsun and Volcano for violations of 93A. Volcano and Axsun moved to dismiss LightLab's 93A counter-claim, and LightLab responded to that motion by amending its 93A counter-claim. The 93A counterclaim has been stayed pending further action by the Chancery Court. This case has been stayed until such time as Volcano has achieved certain development and regulatory milestones. Additionally, on May 24, 2011, LightLab commenced a separate action in Delaware Chancery Court (the Second Chancery Court Action), against Volcano and Axsun alleging that Axsun is inappropriately assisting Volcano in the development of a third-party laser. The complaint seeks injunctive relief and unspecified damages. After Volcano and Axsun moved to dismiss the Second Chancery Court Action, LightLab filed an amended complaint against Volcano and Axsun, adding additional allegations regarding misappropriation of trade secrets. Volcano and Axsun have submitted an answer to the amended complaint. In addition, Volcano and Axsun moved for judgment on the pleadings, seeking to dismiss a portion of LightLab's amended complaint, and have filed an additional motion to stay the remainder of the Second Chancery Court Action. Those motions are currently pending. Litigation—St. Jude On July 27, 2010, St. Jude filed a lawsuit against Volcano in federal district court in Delaware (collectively, with the counterclaims described below, (the Delaware Patent Action), alleging that our pressure guide wire products infringe five patents owned by St. Jude. St. Jude is seeking injunctive relief and monetary damages. This action does not involve OCT technology and is separate from the Massachusetts Action. On September 20, 2010, Volcano filed its response, in which we denied the allegations that our PrimeWire® products infringe any valid claim of St. Jude's asserted patents. In addition, Volcano filed a counterclaim in which we have alleged that St. Jude's PressureWire® products and its RadiAnalyzer® Xpress product infringe three Volcano patents. In our counterclaim, Volcano is seeking injunctive relief and monetary damages. A trial has been scheduled for October 15, 2012 for the Delaware Patent Action. Litigation—Other We may also be a party to various other claims in the normal course of business. Legal fees and other costs associated with such actions are expensed as incurred and were not material in any period reported. Additionally, we assess, in conjunction with our legal counsel, the need to record a liability for litigation and contingencies. Reserve estimates are recorded when and if it is determined that a loss related matter is both probable and reasonably estimable. We are not able to predict or estimate the ultimate outcome or range of possible losses relating to the Massachusetts Action, the Chancery Court Action, the Delaware Patent Action, the Second Chancery Court Action, or any of the other lawsuits, claims or counterclaims described above. However, we believe that the ultimate disposition of these matters, individually and in the aggregate, including the matters discussed above, will not have a material impact on our consolidated results of operations, financial position or cash flows. Our evaluation of the likely impact of these matters could change in the future and unfavorable outcomes and/or defense costs, depending upon the amount and timing, could have a material adverse effect on our results of operations or cash flows in future periods.   Licenses In July 2003, we entered into a license agreement whereby we were granted the rights to certain IVUS technology and patents for total consideration of $6.5 million. This license fee was recorded as an intangible asset and is being amortized over the estimated useful lives of the patents and technology of ten years. In addition, we are paying royalties during the license period related to the sale of our products using the licensed technology. The royalties are calculated on a per unit basis using a sliding scale. During the years ended December 31, 2011, 2010 and 2009, royalty expense related to the use of this licensed technology of $833,000, $680,000, and $690,000, respectively, and is recorded in cost of revenues. In April 2002, we entered into a license agreement with a medical research clinic whereby we were granted a license to certain patents and technology. During the years ended December 31, 2011, 2010 and 2009, we recorded royalty expense of $450,000, $441,000, and $415,000, respectively, in cost of revenues related to this agreement. In June 2010, we entered into a license agreement whereby we were granted to certain patents and technology. During the years ended December 31, 2011 and 2010, we recorded royalty expense of $522,000 and $119,000 respectively, in cost of revenues related to this agreement. We have entered into certain other licensing agreements with third parties which require us to make annual royalty payments based on either a minimum dollar amount or as a percentage of net sales, whichever is higher. None of these other agreements are material to our consolidated results of operations or financial position. Leases We lease our domestic and certain foreign facilities and other equipment under non-cancelable capital and operating lease agreements, which expire at various dates through 2021. In addition to the minimum future lease commitments presented below, the leases generally require that we pay property taxes, insurance, maintenance and repair costs. Certain leases also contain escalation clauses and renewal option clauses calling for increased rents. Where a lease contains an escalation clause or a concession such as a rent holiday, rent expense is recognized using the straight-line method over the term of the lease. At December 31, 2011, future minimum lease commitments under non-cancelable leases are as follows (in thousands):   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0"

expense was $6.9 million, $6.5 million, and $5.7 million for the years ended December 31, 2011, 2010 and 2009, respectively.   Commitments and Other Contractual Obligations We have obligations under non-cancelable purchase commitments. The majority of these obligations related to inventory, primarily raw materials. At December 31, 2011, the future minimum payments under these non-cancelable purchase commitments totaled $32.6 million. Approximately $23.0 million of these commitments will require payment in 12 months, in which 21.5 million of these commitments will require payment prior to March 31, 2012. The remaining amount will require payments at various dates through 2016. We have commitments to provide funding of $4.6 million to a clinical study conducted by a third-party and at December 31, 2011, we have a remaining obligation of up to $2.5 million. We will be billed as services are performed under the agreement. In addition, we have entered into agreements with other third parties to sponsor clinical studies. Generally, we contract with one or more clinical research sites for a single study and no one agreement is material to our consolidated results of operations or financial condition. We are usually billed as services are performed based on enrollment and are required to make payments over periods ranging from less than one year up to three years. Our actual payments under these agreements will vary based on enrollment. In 2010, we acquired a parcel of land in Costa Rica for $3.0 million. In connection with the land acquisition, we also entered into a Fixed Price Building Construction Agreement and a Design, Architecture, Engineering and Construction Management Contract for the completion of a 140,000 square feet operational manufacturing facility. The estimated cost of the construction is approximately $30.5 million which we expect to incur through mid-2012. As of December 31, 2011, the total amount paid related to the construction of the Costa Rica manufacturing facility, including the cost of securing the land for the construction site, is $21.7 million, of which $16.5 million was paid during the year ended December 31, 2011. Indemnification Our supplier, distributor and collaboration agreements generally include certain provisions for indemnification against liabilities if our products are recalled, infringe a third party's intellectual property rights or cause bodily injury due to alleged defects in our products. In addition, we have agreements with our present and former directors and executive officers indemnifying them against liabilities arising from service in their respective capacities to Volcano. We maintain directors' and officers' insurance policies that may limit our exposure to such liabilities. To date, we have not incurred any material costs as a result of such indemnifications and have not accrued any liabilities related to such obligations in the accompanying consolidated financial statements. Sole source suppliers We rely on a number of sole source suppliers to supply transducers, substrates and processing for our scanners used in our catheters. We do not carry significant inventory of transducers, substrates or scanner subassemblies. If we had to change suppliers, we expect that it would take six to 24 months to identify appropriate suppliers, complete design work and undertake the necessary inspections and testing before the new transducers and substrates would be available. We are not parties to supply agreements with these suppliers but instead use purchase orders as needed. </div>

<div> <div> <div> 8. Employee Benefits Defined Contribution Plans We have a defined contribution 401(k) plan for our U.S. employees who are at least 21 years of age. Employees are eligible to participate in the plan beginning on the first day of the month following their first date of hire. Under the terms of the plan, employees may make voluntary contributions as a percent of compensation or as a fixed amount per pay period. During the years ended December 31, 2011, 2010, and 2009, we have made discretionary contributions equal to 25% of participant contributions up to a maximum of 6% of the participant's annual salary totaling $928,000, $793,000, and $710,000, respectively. We also sponsor additional defined contribution plans for most of our European employees. Contributions under all plans were $412,000, $361,000 and $315,000 in the years ended December 31, 2011, 2010 and 2009, respectively. </div></div> </div>

<div> <div> Net Income (Loss) Per Share Basic and diluted net income (loss) per share is presented in accordance with FASB ASC Topic 260, Earnings per Share. Basic net income (loss) per share is computed by dividing consolidated net income (loss) by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing consolidated net income (loss) by the weighted-average number of common shares outstanding and dilutive common stock equivalent shares outstanding during the period. Our potentially dilutive shares include outstanding common stock options, restricted stock units, incremental shares issuable upon the conversion of the Notes or exercise of the warrants relating to the Notes (See Note 3 "Financial Statement Details — Convertible Debt"). Such potentially dilutive shares are excluded when the effect would be to reduce net loss per share or increase net income per share as discussed in the following paragraph. For the year ended December 31, 2011, 2010 and 2009, potentially dilutive shares totaling 1.7 million, 834,000, and 3.9 million, respectively, have not been included in the computation of diluted net income (loss) per share, as the result would be anti-dilutive. Diluted net income per common share includes 12,000 and zero incremental shares related to the Notes for the year ended December 31, 2011 and 2010. Because the principal amount of the Notes will be settled in cash upon conversion, only the conversion spread relating to the Notes may be included in our calculation of diluted net income per common share. As such, the Notes have no impact on diluted net income per common share until the price of our common stock exceeds the conversion price (initially $29.64, subject to adjustments) of the Notes. During the year ended December 31, 2011, 12,000 shares related to the Notes were included in the computation of the diluted net income per common share because the average market price of our common stock during the three months ended September 30, 2011 exceeded the conversion price of the Notes. The average price of our common stock did not exceed the conversion price during any quarter of the year ended December 31, 2010. The diluted net income per common share does not include any incremental shares related to the exercise of the warrants for the year ended December 31, 2011 and 2010. The warrants will not have an impact on diluted net income per common share until the price of our common stock exceeds the strike price of the warrants (initially $34.875, subject to adjustments). When the market price of our stock exceeds strike price, as applicable, we will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued upon exercise of the warrants using the treasury stock method. The call options to purchase our common stock, which we purchased to hedge against potential dilution upon conversion of the Notes (see Note 3 "Financial Statement Details — Convertible Debt"), are not considered for purposes of calculating the total dilutive weighted average shares outstanding, as their effect would be anti-dilutive. Upon exercise, the call options will mitigate the dilutive effect of the Notes. The basic and diluted net income (loss) per common share calculations for the years ended December 31, 2011, 2010, and 2009 are as follows (in thousands, except per share data):   <table

<div> <div> Financial Instruments Financial instruments included in our financial statements are comprised of cash and cash equivalents, available-for-sale investments, foreign exchange forward contracts, accounts receivable, accounts payable, certain accrued liabilities and debt. The carrying amounts of cash and cash equivalents, available-for-sale investments, accounts receivable, accounts payable, accrued liabilities and short-term debt approximate their fair values due to the short-term nature of those instruments. The fair value of our long-term investments approximate their carrying values based upon market rates of interest. The fair value of our Convertible Senior Notes is influenced by interest rates, our stock price, and stock price volatility, which is determined by market trading. In October 2009, we began using foreign exchange forward contracts to manage a portion of the foreign currency risk for our monetary assets denominated in the yen and the euro. We only use derivative financial instruments to reduce the risk that our earnings and cash flows will be affected by changes in exchange rates; we do not hold any derivative financial instruments for trading or speculative purposes. We primarily use forward exchange contracts to hedge foreign currency exposures related to our intercompany receivable balances, and they generally have terms of one year or less. Realized and unrealized gains or losses on the value of financial contracts used to hedge the exchange rate exposure of these monetary assets and liabilities are also included in the determination of net income, as these transactions have not been qualified for hedge accounting. These contracts contain net settlement features. We offset fair value amounts recognized for receivables and payables arising from our foreign exchange forward contracts with each counterparty.</div> </div>

<div> <div> Foreign Currency Translation The euro is the functional currency of Volcano Europe, as it is the primary currency within the economic environment in which Volcano Europe operates. Assets and liabilities of Volcano Europe's operations are translated into U.S. dollars at period-end exchange rates, and revenues and expenses are translated into U.S. dollars at average exchange rates in effect during each reporting period. Adjustments resulting from the translation are reported in other comprehensive income or loss. On July 1, 2009, we adopted the Japanese yen as the functional currency for Volcano Japan. Consistent with the considerations specified in FASB ASC Topic 830, Foreign Currency Matters, the change was made to reflect developments with our Japan operations, including increases in direct sales denominated in the Japanese yen and growth in the local infrastructure that has enabled the day-to-day operations of Volcano Japan to become relatively self-contained and integrated into the Japanese economic environment. At December 31, 2011 and 2010, assets and liabilities of Volcano Japan's operations are translated into U.S. dollars at period-end exchange rates. Commencing July 1, 2009, revenues and expenses are translated into U.S. dollars at average exchange rates in effect during each reporting period and adjustments resulting from the translation are reported on our consolidated balance sheets in accumulated other comprehensive loss. Prior to July 1, 2009, the U.S. dollar was the functional currency of Volcano Japan. For the six months ended June 30, 2009, yen-based expenses were converted into U.S. dollars at average exchange rates in effect during the reporting period and adjustments resulting from the translation were recorded as foreign currency transaction gains or losses and included in exchange rate gain or loss in the consolidated statement of operations. Exchange rate fluctuations resulting from the remeasurement of the inter-company balances between Volcano Corporation, our U.S. entity, and Volcano Japan, and Volcano Corporation and Volcano Europe, and other non-U.S. dollar denominated balances into U.S. dollars are recorded as foreign currency transaction gains or losses and are included in exchange rate gain (loss) in the consolidated statements of operations. On October 1, 2009, approximately $23.4 million of intercompany receivable owed to Volcano Corporation from Volcano Japan was converted into a long-term investment, resulting in a decrease in the amount of yen-based receivables being marked-to-market. The conversion thereby reduced the impact of the exchange rate fluctuations in our consolidated statements of operations. The functional currency of Volcano Costa Rica is the U.S. dollar since it is an extension of the Company's U.S. operations.</div> </div>

<div> <div> Goodwill At December 31, 2011 and 2010, our goodwill resulted from the acquisitions of Axsun and Fluid Medical, Inc. The impairment evaluation for goodwill is conducted annually as of October 1, or more frequently if events or changes in circumstances indicate the carrying value of the goodwill may not be recoverable. We test for goodwill impairment at the reporting unit level, which is at the operating segment level. Our goodwill is allocated entirely to our medical segment. The impairment evaluation involves comparing the fair value of each reporting unit to its carrying value, including goodwill. Fair value reflects the price a market participant would be willing to pay in a potential sale of the reporting unit. If the fair value exceeds carrying value, then it is concluded that no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its fair value, a second step is required to measure possible goodwill impairment loss. In the second step, the implied fair value of the goodwill is determined by allocating the fair value of all of the reporting unit's assets and liabilities other than goodwill in a manner similar to a purchase price allocation. The resulting implied fair value of the goodwill that results from the allocation is then compared to the carrying amount of the goodwill and an impairment charge is recorded for the difference. There was no impairment of goodwill during the years ended December 31, 2011, 2010 or 2009.</div> </div>

At December 31, 2011, based on the weight of available evidence, including cumulative profitability in recent years and the availability of expected future taxable income, the Company concluded that it is more likely than not that the benefits of some of the Company's deferred income tax assets will be realized. Accordingly, the Company reversed the valuation allowance on the Company's federal and a portion of its state gross deferred income tax assets. In February 2009, the California 2009-2010 budget legislature was enacted into law, allowing companies to elect, for income tax purposes, to apply a single sales factor apportionment for years beginning after January 1, 2011. Based upon its anticipated election, the Company is continuing to maintain a valuation allowance to offset a portion of its California deferred tax assets as realization of a portion of such assets does not meet the more-likely-than-not threshold required under accounting guidelines. At December 31, 2010 and 2009, a valuation allowance was established within the U.S. and selected international jurisdictions to offset deferred tax assets, as realization of such assets is not more likely than not. Included in our net deferred tax asset balance at December 31, 2011 is a $1.7 million net deferred tax asset representing future tax deductions of original issue discount in excess of book expense related to the Company's hedge transaction associated with its Notes. The Company concluded that it is more likely than not that the benefit of the deferred income tax will be realized. Accordingly, the Company reversed the valuation allowance on this asset. The benefit attributable to such asset was recognized as an increase to additional-paid-in-capital. As of December 31, 2010, the aforementioned deferred tax asset of $1.7 million and corresponding valuation allowance were recorded with an offset to additional-paid-in-capital. As a result of certain realization requirements of ASC 718, the table of deferred tax assets shown above does not include certain deferred tax assets at December 31, 2011 and 2010 that arose directly from tax deductions related to equity compensation in excess of compensation recognized for financial reporting. Equity will be increased by approximately $47.8 million if and when such deferred tax assets are ultimately realized. We use the with-and-without approach ignoring indirect effects for purposes of determining when excess tax benefits have been realized. Stock option excess tax benefits of $165,000 and $433,000 were credited to additional paid-in-capital during the year ended December 31, 2011 and 2010. At December 31, 2011, we have federal and state net operating loss carry forwards of approximately $68.5 million and $39.6 million, respectively. The federal and state net operating loss carry forwards begin to expire in 2021 and 2012, respectively, unless previously utilized. In addition, we have federal and state research and experimentation tax credit carry forwards of approximately $5.8 million and $6.8 million, respectively. The federal credits begin to expire in 2022. The California state credits carry forward indefinitely. The Massachusetts state credit carry forwards begin to expire in 2019. Foreign net operating losses are approximately $14.6 million and carry forward indefinitely. Pursuant to Internal Revenue Code Section 382, use of net operating loss carry forwards related to acquisitions of approximately $29.4 million may be limited. These carry forwards will expire if we are unable to generate sufficient taxable income within the carry forward period. At December 31, 2011, the total amount of gross unrecognized tax benefits, including interest and penalties, was approximately $1.1 million. If recognized, these benefits would affect our effective tax rate.

<div> <div> Income Taxes We use the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and tax operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. To the extent a deferred tax asset cannot be recognized under the preceding criteria, allowances are established.   In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. During the fourth quarter of 2011, we concluded that it was more likely than not that we would be able to realize the benefit of a significant portion of our deferred tax assets in the future. We based this conclusion on historical and projected operating performance, as well as our expectation that our operations will generate sufficient taxable income in future periods to realize the tax benefit associated with the deferred tax assets. As a result, we released $22 million of the valuation allowance on our net federal and state deferred tax assets. We believe it is more likely than not that the benefit from certain international net operating losses and a portion of our state deferred tax assets will not be realized. In recognition of this risk, we will continue to provide a valuation allowance on the deferred tax assets relating to these items. We will continue to assess the need for a valuation allowance on the deferred tax asset by evaluating both positive and negative evidence that may exist. Any adjustment to the net deferred tax asset valuation allowance would be recorded in the income statement for the period that the adjustment is determined to be required. At December 31, 2010 and 2009, within the U.S. and selected international jurisdictions, all deferred tax assets, without offsetting liabilities in the same jurisdiction, were fully offset by a valuation allowance. FASB ASC Topic 740, Income Taxes, or ASC 740, clarifies the accounting for uncertainty in income taxes recognized in the financial statements. ASC 740 provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. ASC 740 also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. We accrue interest and penalties on underpayment of income taxes related to unrecognized tax benefits as a component of income tax expense in our consolidated statements of operations. The amounts recognized for interest and penalties during the years ended December 31, 2011, 2010 and 2009 were $34,000, $25,000, and $23,000, respectively. </div> </div>

<div> <div> Inventories Inventories are valued at the lower of first-in, first-out cost or market value. Inventory provisions are recorded for materials that have become obsolete or are no longer used in current production and for inventory that has a market value less than the carrying value in inventory. We regularly monitor potential inventory excess, obsolescence and lower market values compared to standard costs and, when necessary, reduce the carrying amount of our inventory to its market value. Specific reserves are maintained to reduce the carrying value of inventory items on hand that we know may not be used in finished goods. If our estimates for potential inventory losses prove to be too low, then our future earnings will be affected when the related additional inventory losses are recorded. </div> </div>

<div> <div> Our Company Volcano Corporation, or we, us, our, Volcano or the Company, was incorporated under the laws of the State of Delaware on January 12, 2000. We design, develop, manufacture and commercialize a broad suite of precision guided therapy products including intravascular ultrasound, or IVUS, and fractional flow reserve, or FFR, products that we believe enhance the diagnosis and treatment of vascular and structural heart disease. We are facilitating the adoption of functional percutaneous coronary intervention, or PCI, in which our FFR technology is used to determine whether or not a stent is necessary, and IVUS is used to guide stent placement and optimization. We market our products to physicians and technicians who perform PCI procedures in hospitals and to other personnel who make purchasing decisions on behalf of hospitals. Our products consist of multi-modality consoles which are marketed as stand-alone units or as customized units that can be integrated into a variety of hospital-based interventional surgical suites called catheterization laboratories, or cath labs. Our consoles have been designed to serve as a multi-modality platform for our phased array and rotational IVUS catheters, FFR pressure wires, image-guided therapy catheters and Medtronic's Pioneer reentry device. Our IVUS products include single-procedure disposable phased array and rotational IVUS imaging catheters and additional functionality options such as virtual histology tissue characterization, or VH, and ChromaFlo stent apposition analysis. Our FFR offerings can be accessed through our multi-modality platforms, and we also provide FFR-only consoles. Our FFR disposables are single-procedure disposable pressure and flow guide wires used to measure the pressure and flow characteristics of blood around plaque enabling physicians to gauge the plaque's physiological impact on blood flow and pressure. We are developing additional offerings for integration into the platform, including adenosine-free Instant™ wave-free ratio FFR, or iFR, forward-looking IVUS or FL.IVUS, catheters, Focal Acoustic Computed Tomography catheters and ultra-high resolution Optical Coherence Tomography, or OCT, systems and catheters. We also develop and manufacture optical monitors for the telecommunication industry; laser and non-laser light sources, and optical engines used in the medical OCT imaging systems and advanced photonic components and sub-systems used in spectroscopy and other industrial applications.</div> </div>

Financial Statement Details Cash and Cash Equivalents and Available-for-Sale Investments We invest our excess funds in securities issued by the U.S. government, corporations, banks, municipalities, financial holding companies and in money market funds comprised of these same types of securities. Our cash and cash equivalents and investments are placed with high credit quality financial institutions. Additionally, we diversify our investment portfolio in order to maintain safety and liquidity. As of December 31, 2011, all of our investments will mature within 17 months. These investments are recorded at their estimated fair value including accrued interest receivable, with unrealized gains or losses reported as a separate component of accumulated other comprehensive income or loss. Fair value is defined as an exit price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Authoritative guidance establishes a three-level hierarchy for disclosure that is based on the extent and level of judgment used to estimate the fair value of assets and liabilities.   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="100%"> <tr><td width="5%"> </td> <td valign="top" width="2%" align="left"></td> <td valign="top" width="1%"> </td> <td valign="top" align="left"> Level 1—Valuations based on quoted prices for identical assets or liabilities in active markets at the measurement date. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Our Level 1 assets consist of money market funds and U.S. Treasury and agency debt securities. </td></tr></table>   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="100%"> <tr><td width="5%"> </td> <td valign="top" width="2%" align="left"></td> <td valign="top" width="1%"> </td> <td valign="top" align="left"> Level 2—Valuations based on quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data, such as alternative pricing sources with reasonable levels of price transparency. Our Level 2 assets consist of corporate debt securities including commercial paper, corporate bonds, certificates of deposit and foreign currency forward contracts. </td></tr></table>   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="100%"> <tr><td width="5%"> </td> <td valign="top" width="2%" align="left"></td> <td valign="top" width="1%"> </td> <td valign="top" align="left"> Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement. We have not measured the fair value of any of our assets using Level 3 inputs. </td></tr></table> We utilize a third-party pricing service to assist us in obtaining fair value pricing for our investments. Pricing for securities is based on proprietary models. Inputs are documented in accordance with the fair value disclosure hierarchy. We utilize third-party financial institutions to assist us in obtaining fair value pricing for our foreign currency forward contracts. During the twelve months ended December 31, 2011 and 2010, no transfers were made into or out of the Level 1, 2, or 3 categories. We will continue to review our fair value inputs on a quarterly basis. Financial assets and liabilities measured at fair value on a recurring basis are summarized below at December 31, 2011 and 2010 (in thousands):   <div> <table style="border-collapse: collapse;"

Instruments Our derivative financial instruments include foreign exchange forward contracts. Commencing October 2009, we begin using foreign exchange forward contracts to manage a portion of the foreign currency risk related to our intercompany receivable balances with our foreign subsidiaries whose functional currencies are the euro and yen. We record derivative financial instruments as either assets or liabilities in our consolidated balance sheets and measure them at fair value. At December 31, 2011 and 2010, the notional amount of our outstanding contracts was $59.3 million and $54.0 million, respectively. At December 31, 2011, our outstanding derivatives had maturities of 228 days or less. The fair value of our foreign exchange forward contracts of $92,000 and $0 was included in prepaid and other current assets and $71,000 and $299,000 was included in accrued expense and other current liabilities in our consolidated balance sheet at December 31, 2011 and 2010, respectively. For the year ended December 31, 2011, 2010 and 2009, $1.3 million and $3.2 million of losses and $715,000 of gains, respectively, related to our derivative financial instruments are included in exchange rate gain (loss) in our consolidated statements of operations. In connection with our convertible debt offering (discussed in more detail below) we purchased call options on our common stock from JPMorgan Chase. The call options give us the right to purchase up to approximately 3.9 million shares of our common stock at $29.64 per share subject to certain adjustments that generally correspond to the adjustments to the conversion rate for the underlying debt. Additionally, we sold warrants to JPMorgan Chase, which give JPMorgan Chase the right to purchase up to approximately 3.9 million shares of our common stock at $34.875 per share, subject to certain adjustments. In accordance with the authoritative guidance, we concluded that the call options and warrants were indexed to our stock.

We retain the ownership of the equipment and have the right to remove the equipment if it is not being utilized according to expectations. Depreciation expense relating to the equipment of $10.9 million, $8.2 million and $4.8 million is recorded in cost of revenues during the years ended December 31, 2011, 2010 and 2009, respectively. The net book value of this equipment was $25.9 million and $28.6 million at December 31, 2011 and December 31, 2010, respectively. Also included in medical diagnostic equipment is property and equipment used for demonstration and evaluation purposes. Depreciation expense for equipment used for demonstration and evaluation purposes recorded in selling, general and administrative expenses totaled $1.2 million, $1.5 million and $1.8 million during the years ended December 31, 2011, 2010 and 2009, respectively. The net book value of this equipment was $1.4 million and $1.6 million at December 31, 2011 and December 31, 2010, respectively. Medical diagnostic equipment is recorded at our cost to acquire or manufacture the equipment and is depreciated over its estimated useful life (generally three to five years). Depreciation expense for the years ended December 31, 2011, 2010 and 2009 was $19.8 million, $16.0 million, and $12.0 million, respectively. Intangible Assets Intangible assets consisted of acquired developed technology, licenses, customer relationships, assembled technology, patents and trademarks, as well as acquired in-process technology. Intangible assets related to developed technology, licenses, patents and trademarks, customer relationships, and assembled technology are amortized using the straight-line method over their estimated useful lives of up to 20 years. Amortization of acquired in-process technology will not commence until the technology reaches market feasibility. Upon a decision by management to abandon an in-process technology project, the related intangible assets are charged to expense. During the year ended December 31, 2011, we recorded intangible asset additions of $1.4 million related to internally developed patents and trademarks, $104,000 related to customer relationships and $161,000 related to licensed technology. During the year ended December 31, 2010, we recorded intangible asset additions of $8.1 million primarily consisting of $4.1 million of acquired IPR&D, $2.0 million related to acquisition of developed technology, $1.4 million of customer relationships, and $429,000 related to internally developed patents and trademarks.

As part of the restructuring plan, during the first quarter of 2010 we closed our San Antonio, Texas facility and relocated such operations to our Billerica, Massachusetts facility. Approximately 20 employees were impacted by the restructuring plan. One-time benefits to affected employees included relocation or a separation agreement including severance payments, continuing medical benefits, and outplacement assistance. Sixteen employees entered into separation agreements. All terminations were completed as of May 31, 2010 and no outstanding liability related to this restructuring as of December 31, 2011 and 2010. We accrued relocation costs and the costs of one-time termination benefits to employees who were not required to render service beyond a minimum retention period of 60 days. The remaining one-time termination benefits were recorded to expense ratably over required service periods. Additionally, costs related to moving equipment between the facilities were expensed during the period incurred. As a result, we recorded $63,000 as research and development expense during the year ended December 31, 2010. In addition, during the first quarter of 2010 we recorded $454,000 of additional restructuring costs as selling, general and administrative expense for the termination of the operating lease and related contract costs, and a charge for the impairment of certain property and equipment. On April 26, 2010, we entered into a lease termination agreement with the landlord of our San Antonio facility. Total termination costs of $330,000 included a lump-sum lease-termination payment, broker commissions and the surrender of our security deposit. We are correspondingly released from any future obligations under this facility lease. The termination payment represented a savings over the original estimated restructuring liability related to the remaining lease payments and resulted in a benefit of $116,000 that was recorded during the second quarter. At December 31, 2010, there were no future obligations remaining in accrued liabilities related to this restructuring activity.   At December 31, 2010 and 2009, our restructuring liability included in accrued expenses and other current liabilities of our consolidated balance sheets (in thousands) is detailed as follows:   <table style="border-collapse: collapse;" border="0" cellspacing="0"

See Note 4 "Commitments and Other Contractual Obligations" for more information. Convertible Debt In September 2010, we issued $115.0 million aggregate principal amount of Notes, in an offering registered under the Securities Act of 1933, as amended. Interest is payable semiannually in arrears on March 1 and September 1, commencing on March 1, 2011. The Notes are general unsecured obligations that rank pari passu with our other existing and future unsecured obligations. Prior to June 1, 2015, the Notes are convertible only upon certain specified events. The initial conversion rate for the Notes is 33.7339 shares of common stock per $1,000 principal amount of the Notes, representing an initial effective conversion price of approximately $29.64 per share of common stock. The conversion rate is subject to adjustment for certain events as outlined in the indenture governing the Notes but will not be adjusted for accrued and unpaid interest. We received proceeds of $100.5 million from issuance of the Notes, net of debt issuance costs ($4.4 million) and net payments related to our hedge transactions ($10.0 million) which are described in more detail below. We recorded total debt issuance costs (including broker fees) of approximately $4.4 million, which have been allocated on a pro-rata basis to the debt ($3.5 million) and equity ($866,000) components of the transaction. The debt component is primarily included in non-current liabilities and is being accreted to interest expense over five years, the term of the Notes. The equity component was netted against the proceeds and included in additional paid-in capital. The carrying values of the liability and equity components of the Notes are reflected in our consolidated balance sheets as follows (in thousands):   <table style="border-collapse: collapse;"

However, in the event of a fundamental change, as defined in the indenture, the holders of the Notes may require us to purchase all or a portion of their Notes at a purchase price equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to the repurchase date. Holders, who convert their Notes in connection with a make-whole fundamental change, as defined in the indenture, may be entitled to a make-whole premium in the form of an increase in the conversion rate. Prior to June 1, 2015, the Notes are convertible only under the following circumstances: (1) during any fiscal quarter commencing after December 31, 2010 (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period (the "Measurement Period") in which, for each trading day of such Measurement Period, the trading price per $1,000 principal amount of notes on such trading day was less than 98% of the product of the last reported sale price of our common stock on such trading day and the applicable conversion rate on such trading day; or (3) upon the occurrence of specified distributions and corporate events. As of December 31, 2011, the "if-converted" value of the Notes did not exceed its principal amount and none of the conditions allowing holders of the Notes to convert had been met. The total fair value of the Notes at December 31, 2011 was $123.5 million. We determined that the embedded conversion option in the Notes is not required to be separately accounted for as a derivative under ASC 815, Derivatives and Hedging. However, since the Notes are within the scope of ASC 470, Topic 20, Debt with Conversion and Other Options, we are required to separate the Notes into a liability component and equity components. The carrying amount of the liability component is calculated by measuring the fair value of a similar liability (including any embedded features other than the conversion option) that does not have an associated equity component. The carrying amount of the equity component representing the embedded conversion option is determined by deducting the fair value of the liability component from the initial proceeds ascribed to the Notes as a whole. The excess of the principal amount of the liability component over its carrying amount is amortized to interest cost over the expected life of a similar liability that does not have an associated equity component using the effective interest method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification in ASC 815, Topic 40, Contracts in an Entity's Own Equity, or ASC 815. We are using an effective interest rate of 7.65% to calculate the accretion of the bond discount, which is being recorded as interest expense over the expected remaining term of the Notes. (The amount by which interest expense calculated using the effective interest rate of 7.65% exceeds the interest expense related to the coupon rate of 2.875%, is non-cash interest expense.) The effective rate is based on the interest rate for a similar instrument that does not have a conversion feature. We may be required to pay additional interest upon occurrence of certain events as outlined in the indenture governing the Notes. As of December 31, 2011, the remaining term of the Notes is 3.67 years.   Upon conversion of a Note, holders of the Notes will receive up to the principal amount of the converted Note in cash and any excess conversion value (conversion spread) in shares of our common stock. The amount of cash and the number of shares of our common stock, if any, will be based on a 25 trading day observation period as described in the indenture. As described in Note 1 "Organization and Summary of Significant Accounting Policies", the conversion spread will be included in the denominator for the computation of diluted net income per common share, using the treasury stock method. As discussed above, to hedge against potential dilution upon conversion of the Notes, we also purchased call options on our common stock from JPMorgan Chase. The call options give us the right to purchase up to approximately 3.9 million shares of our common stock at $29.64 per share subject to certain adjustments that generally correspond to the adjustments to the conversion rate for the Notes. We paid an aggregate of $27.2 million to purchase these call options. The call options will expire on September 1, 2015, unless earlier terminated or exercised. To reduce the cost of the hedge, in a separate transaction we sold warrants to JPMorgan Chase. These warrants give JPMorgan Chase the right to purchase up to approximately 3.9 million shares of our common stock at $34.875 per share, subject to certain adjustments. These warrants will be exercisable and will expire in equal installments for a period of 50 trading days beginning on December 1, 2015. We received an aggregate of $17.1 million from the sale of these warrants. In accordance with ASC 815, we concluded that the call options and warrants were indexed to our stock. Therefore, the call options and warrants were classified as equity instruments and will not be marked to market prospectively unless certain conditions as described in the Notes occur. The net amount of $10.0 million paid to JPMorgan Chase was recorded as a reduction to additional paid-in capital. The settlement terms of the call options provide for net share settlement and the settlement terms of the warrants provide for net share or cash settlement at our option. </div></div> </div>

<div> <div> Long-Lived Assets Our long-lived assets consist of property and equipment and intangible assets. Property and equipment are stated at cost, net of accumulated depreciation and amortization. Equipment and capitalized software are depreciated over the estimated useful lives of the assets, which range generally from three to ten years. Leasehold improvements are amortized over the lesser of the lease term including renewal periods that are reasonably assured or the estimated useful lives of the improvements, which are between three and ten years. The straight-line method is used for depreciation and amortization. Land is stated at cost and is not depreciated. Significant improvements which substantially extend the useful lives of assets are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred. Assets held under capital leases are recorded at the net present value of the minimum lease payments of the leased asset at the inception of the lease. Amortization expense is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the period of the related lease and is included in our depreciation expense. We record intangible assets at historical cost and amortize them over their estimated useful lives. Intangible assets consist of acquired developed technology, licenses, customer relationships, assembled technology, patents and trademarks, as well as acquired in-process technology. Intangible assets related to developed technology, licenses, patents and trademarks, customer relationships, and assembled technology are amortized using the straight-line method over their estimated useful lives of up to 20 years. Amortization of acquired in-process technology will not commence until the technology reaches market feasibility. Upon a decision by management to abandon an in-process technology project, the related intangible assets are charged to expense.   Our long-lived assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. When evaluating long-lived assets for potential impairment, we first compare the carrying value of the asset to the asset's estimated future cash flows (undiscounted and without interest charges). If the estimated future cash flows are less than the carrying value of the asset, we calculate an impairment loss. The impairment loss calculation compares the carrying value of the asset to the asset's estimated fair value, which may be based on estimated future cash flows (discounted and with interest charges). No impairment of long-lived assets and identifiable intangibles was identified or recorded during the years ended December 31, 2011, 2010 or 2009.</div> </div>
