FOOTNOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(1)    Basis of Presentation
The condensed consolidated balance sheet of ION Geophysical Corporation and its subsidiaries (collectively referred to as the “Company” or “ION,” unless the context otherwise requires) at December 31, 20162017 has been derived from the Company’s audited consolidated financial statements at that date. The condensed consolidated balance sheet at September 30, 2017,2018, and the condensed consolidated statements of operations and comprehensive income (loss) for the three and nine months ended September 30, 20172018 and 20162017 and the condensed consolidated statements of cash flows for the nine months ended September 30, 20172018 and 2016,2017, are unaudited. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The results of operations for the three and nine months ended September 30, 20172018, are not necessarily indicative of the operating results for a full year or of future operations.
The Company hasCompany’s financial statements reflect a non-redeemable noncontrolling interestsinterest in a majority-owned affiliatesaffiliate which areis reported as a separate component of equity in “Noncontrolling interests”interest” in the condensed consolidated balance sheets. The activity for this noncontrolling interest relates to proprietary processing projects in Brazil.
These condensed consolidated financial statements have been prepared using accounting principles generally accepted in the United States for interim financial information and the instructions to Form 10-Q and applicable rules of Regulation S-X of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in annual financial statements presented in accordance with accounting principles generally accepted in the United States have been omitted. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K as amended for the year ended December 31, 20162017.
(2)    Recent Accounting Pronouncements
In February 2016, the Financials Account Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842)” which introduces the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. The guidance will be effective for annual reporting periods beginning after December 15, 2018 and interim periods within those fiscal years with early adoption permitted. The Company will adopt ASU 2016-02 on January 1, 2019. The Company is currently evaluating its operating leases related to offices, processing centers, warehouse spaces and, to a lesser extent, certain equipment. The Company expects the adoption of the standard will add between $50 million to $60 million in right-of-use assets and lease obligations on its consolidated balance sheet and will not significantly impact it’s income statement. The Company plans to elect the practical expedients upon transition which will retain the lease classification for leases that exist prior to the adoption of the standard.
On January 1, 2018, the Company adopted FASB Accounting Standard Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers” and all the related amendments using the modified retrospective method. The adoption did not have a material impact to the Company’s revenue recognition policy under the previous standard (ASC 605) and adoption of the new standard, ASC 606, did not result in an adjustment to the Company’s beginning retained earnings balance.
On January 1, 2018, the Company adopted ASU 2016-18, Statement of Cash Flows - “Restricted Cash (a consensus of the FASB Emerging Issues Task Force) (ASU 2016-18)”, using a retrospective transition method to each period presented. The new standard no longer requires the Company to present transfers between cash and cash equivalents and restricted cash in the statement of cash flows. Adoption of the new standard resulted in a decrease of $0.3 million in net cash provided by operating activities as previously reported for the nine months ended September 30, 2018. See the consolidated statement of cash flows above which includes a reconciliation of cash and cash equivalents to total cash, cash equivalents, and restricted cash.
(3)    Segment Information
The Company evaluates and reviews its results based on three business segments: E&P Technology & Services, Operations Optimization (formerly referred to as E&P Operations Optimization,Optimization), and Ocean Bottom Integrated Technologies (formerly referred to as Ocean Bottom Seismic Services.Services). The Company measures segment operating results based on income (loss) from operations.

(3)(4)     Revenue From Contracts With Customers
The Company derives revenue from the sale or license of (i) multi-client and proprietary data, imaging services and E&P Advisors consulting services within its E&P Technologies & Services segment; (ii) seismic data acquisition systems and other seismic equipment, (iii) seismic command and control software systems and software solutions for operations management within its Operations Optimization segment; and (iv) a full suite of technology and services within its Ocean Bottom Integrated Technologies segment. All revenues of the E&P Technology & Services and Ocean Bottom Integrated Technologies segments and the services component of revenues for the Optimization Software & Services group as part of the Operations Optimization segment are classified as services revenues. All other revenues are classified as product revenues.
The Company uses a five-step model to determine proper revenue recognition from customer contracts. Revenue is recognized when (i) a contract is approved by all parties; (ii) the goods or services promised in the contract are identified; (iii) the consideration we expect to receive in exchange for the goods or services promised is determined; (iv) the consideration is allocated to the goods and services in the contract; and (v) control of the promised goods or services is transferred to the customer. The Company does not disclose the value of contractual future performance obligations such as backlog with an original expected length of one year or less within the footnotes.

Multi-client and Proprietary Surveys, and Imaging and E&P Advisors Services - As multi-client seismic surveys are being designed, acquired or processed (the “New Venture” phase), the Company enters into non-exclusive licensing arrangements with its customers, who pre-fund or underwrite these programs in part. License revenues from these surveys are recognized during the New Venture phase as the seismic data is acquired and/or processed on a proportionate basis as work is performed and control is transferred to the customer. Under this method, the Company recognizes revenue based upon quantifiable measures of progress, such as kilometers acquired or surveys of performance completed to date. Upon completion of a multi-client seismic survey, it is considered “on-the-shelf,” and licenses to the survey data are granted to customers on a non-exclusive basis.
The Company also performs seismic surveys, imaging and other services under contracts to specific customers, whereby the seismic data is owned by those customers. The Company recognizes revenue as the seismic data is acquired and/or processed on a proportionate basis as work is performed. The Company uses quantifiable measures of progress consistent with its multi-client seismic surveys.
Acquisition Systems and Other Seismic Equipment - For sales of seismic data acquisition systems and other seismic equipment, the Company recognizes revenue when control of the goods has transferred to the customer. Transfer of control generally occurs when (i) the Company has a present right to payment; (ii) the customer has legal title to the asset; (iii) the Company has transferred physical possession of the asset; (iv) the customer has significant rewards of ownership; and/or (v) the customer has accepted the asset.
Software - Licenses for the Company’s navigation, survey design and quality control software systems provide the customer with a right to use the software. The Company offers usage-based licenses under which it receives a monthly fee based on the number of vessels and licenses used. For these usage-based licenses, revenue is recognized as the performance obligations are performed over the contract term, which is generally two to five years. In addition to usage-based licenses, the Company offers perpetual software licenses as it exists when made available to the customer. Revenue from these licenses is recognized upfront at the point in time when the software is made available to the customer.
These arrangements generally include the Company providing related services, such as training courses, engineering services and annual software maintenance. The Company allocates consideration to each element of the arrangement based upon directly observable or estimated standalone selling prices. Revenue is recognized for these services as control transfers to the customer over time.
Ocean Bottom Integrated Technologies - The Company recognizes revenue as the seismic data is acquired and control transfers to the customer. The Company uses quantifiable measures of progress consistent with our multi-client surveys. In connection with acquisition contracts, the Company may receive revenues for preparation and mobilization of equipment and personnel, capital improvements to vessels, or demobilization activities. The Company defers the revenues earned and incremental costs incurred that are directly related to these activities and recognizes such revenues and costs over the primary contract term of the acquisition project as we transfer the goods and services to the customer. The Company recognizes the costs of relocating vessels without contracts to more promising market sectors as such costs are incurred.

Deferred Revenue
Billing practices are governed by the terms of each contract based upon achievement of milestones or pre-agreed schedules. Billing does not necessarily correlate with revenue recognized on a proportionate basis as work is performed and control is transferred to the customer. Deferred revenue represents cash received in excess of revenue not yet recognized as of the reporting period, but will be recognized in future periods.

(5)(7)    Income Taxes
The Company maintains a valuation allowance for substantially all of its deferred tax assets. The valuation allowance is calculated in accordance with the provisions of the Financial Accounting Standards Board’s (“FASB”) Accounting Standard Codification (“ASC”)ASC Topic 740 “Income Taxes,” which requires that a valuation allowance be established or maintained when it is “more likely than not” that all or a portion of deferred tax assets will not be realized. In the event the Company’s expectations of future operating results change, the valuation allowance may need to be adjusted downward. As of September 30, 2017, the Company has no unreserved U.S. deferred tax assets.
The tax provision for the nine months ended September 30, 20172018 has been calculated using the Company’s overall estimated annual effective tax rate based on projected 2018 full year results. The tax provision includes impacts of the actual tax expense incurred for the period. Given the current uncertainty in expected income generated in various foreign jurisdictions, where tax rates can vary greatly,Tax Cut and Jobs Act enacted on December 22, 2017, however, these impacts are minimal due to the Company’s actual tax rate is the best estimate of year-to-date tax expense.U.S. net operating loss and valuation allowance position. The Company’s effective tax rates for the three months ended September 30, 2018 and 2017 were (38.6)% and 2016 were 25.2% and 63.4%, respectively. The Company’s effective tax raterates for the nine monthsnine-months ended September 30, 2018 and 2017 and 2016 were (15.1)(6.9)% and (11.2)(15.1)%, respectively. The Company’s effective tax rates for the three and nine months ended September 30, 2018 and 2017 were negatively impacted by the change in valuation allowance related to U.S. operating losses for which the Company cannot currently recognize a tax benefit. The Company’s income tax expense for the nine months ended September 30, 20172018 of $3.7$3.3 million primarily relates to results from the Company’s non-U.S. businesses.
The Company has approximately $1.3$0.4 million of unrecognized tax benefits and does not expect to recognize significant increases in unrecognized tax benefits during the next 12-month period. Interest and penalties, if any, related to unrecognized tax benefits are recorded in income tax expense.
As of September 30, 2017,2018, the Company’s U.S. federal tax returns for 20132014 and subsequent years remain subject to examination by tax authorities. The Company is no longer subject to U.S. Internal Revenue Service (“IRS”) examination for periods prior to 2013, although carryforward attributes related to losses generated prior to 2013 may still be adjusted upon examination by the IRS if they either have been or will be used in an open year. In the Company’s foreign tax jurisdictions, tax returns for 20102013 and subsequent years generally remain open to examination.

(6)(8) Litigation
WesternGeco
In June 2009, WesternGeco L.L.C. (“WesternGeco”) filed a lawsuit against the Company in the United States District Court for the Southern District of Texas, Houston Division. In the lawsuit, styled WesternGeco L.L.C. v. ION Geophysical Corporation, WesternGeco alleged that the Company had infringed several method and apparatus claims contained in four of its United States patents regarding marine seismic streamer steering devices.
The trial began in July 2012. A verdict was returned by the jury in August 2012, finding that the Company infringed the claims contained in the four patents by supplying its DigiFIN® lateral streamer control units and the related software from the United States and awarded WesternGeco the sum of $105.9 million in damages, consisting of $12.5 million in reasonable royaltyroyalties and $93.4 million in lost profits.
In June 2013, the presiding judge entered a Memorandum and Order, rulingdenying the Company’s post-verdict motions that challenged the jury’s infringement findings and the damages amount. In the Memorandum and Order, the judge also ruled that WesternGeco iswas entitled to be awarded supplemental damages for the additional DigiFIN units that were supplied from the United States before and after the trial that were not included in the jury verdict due to the timing of the trial. In October 2013, the judge entered another Memorandum and Order, ruling on the number of DigiFIN units that arewere subject to supplemental damages and also ruling that the supplemental damages applicable to the additional units shouldwere to be calculated by adding together the jury’s previous reasonable royalty and lost profits damages awards per unit, resulting in supplemental damages of $73.1 million.

In April 2014, the judge entered another Order, ruling that lost profits should not have been included in the calculation of supplemental damages in the October 2013 Memorandum and Order and reducedreducing the supplemental damages award in the case from $73.1 million to $9.4 million. In the Order, the judge also further reduced the damages awardawarded in the case by $3.0 million to reflect a settlement and license that WesternGeco entered into with a customer of the Company that had purchased and used DigiFIN units that were also included in the damage amounts awarded against the Company.
In May 2014, the judge signed and entered a Final Judgment against the Company in the amount of $123.8 million related to the case.million. The Final Judgment also included an injunction that enjoins the Company, its agents and anyone acting in concert with it, from supplying in or from the United States the DigiFIN product or any parts unique to the DigiFIN product, or any instrumentality no more than colorably different from any of these products or parts, for combination outside of the United States. The Company has conducted its business in compliance with the District Court’s orders in the case, and the Company has reorganized its operations such that it no longer supplies the DigiFIN product or any parts unique to the DigiFIN product in or from the United States.
The Company and WesternGeco each appealed the Final Judgment to the United States Court of Appeals for the Federal Circuit in Washington, D.C. (the “Court of Appeals”). On July 2, 2015, the Court of Appeals reversed in part the judgment,Final Judgment of the District Court, holding the District Court erred by including lost profits in the Final Judgment. Lost profits were $93.4 million and prejudgment interest on lost profits was approximately $10.9 million of the $123.8 million Final Judgment. Pre-judgment interest on the lost profits portion will be treated in the same way as the lost profits. Post-judgment interest will likewise be treated in the same fashion. On July 29, 2015, WesternGeco filed a petition for rehearing en banc before the Court of Appeals. On October 30, 2015 the Court of Appeals denied WesternGeco’s petition for rehearing en banc.
As previously disclosed, the Company recorded a loss contingency accrual of $123.8 million. As a result of the reversal by the Court of Appeals, as of June 30, 2015, the Company reduced its loss contingency accrual to $22.0 million.
On February 26, 2016, WesternGeco filed a petition for writ of certiorari by the Supreme Court. The Company filed its response on April 27, 2016. Subsequently, on June 20, 2016, the Supreme Court refused to disturbvacated the Court of AppealsAppeals’ ruling finding noalthough it did not address the lost profits as a matter of law.  Separately,question at that time. Rather, in light of the changes in case law regarding the standard of proof for willfulness in the Halo and Stryker cases, the Supreme Court indicated that the case should be remanded to the Federal CircuitCourt of Appeals for a determination of whether or not the willfulness determination by the District Court was appropriate.
On October 14, 2016, the Court of Appeals issued a mandate returning the case to the District Court for consideration of whether or not additional damages for willfulness were appropriate.
On November 14, 2016, the District Court issued an order reducing the amount of the appeal bond from $120.0 million to $65.0 million, ordered the sureties to pay principal and interest on the royalty damages previously awarded and declined to issue a final judgment until after consideration of whether enhanced damages related tofor willfulness shouldwould be awarded in the case.awarded. While the Company did not agreedisagreed with the unusual decision by the District Court ordering payment of the royalty damages and interest without a final judgment, on November 25, 2016, the Company paid WesternGeco the $20.8 million due pursuant to the order, at which point the Company reduced its loss contingency accrual to WesternGeco on November 25, 2016.zero.

On March 14, 2017, the District Court held a hearing on whether or not additional damages for willfulness would be payable. The Judge found that ION’sthe Company’s infringement was willful, based on his perception that IONthe Company did not adequately investigate the scope of the patent,patents, and ION’sthe Company’s conduct during trial. However, in his May 16, 2017 order,ruling at the hearing, he limited enhanced damages to $5.0 million because it was a “close case,” there was no evidence of copying, and IONthe Company was simply acting as a competitor in a capitalist marketplace. The District Court also ordered the appeal bond to be released and discharged. The Court’s findings and ruling were memorialized in an order issued on May 16, 2017. On June 30, 2017, WesternGeco and the Company jointly agreed that neither party would appeal the District Court's award of $5.0 million in enhanced damages. The parties also agreed that the $5.0 million would be paid over the course of 12 months with $1.25 million being paid in two installments of $0.625 million in 2017 and the remaining $3.75 million being paid in three quarterly payments of $1.25 million beginning January 1, 2018.months. This agreement was memorialized by the court in an order issued on July 26, 2017. Upon assessment of the $5.0 million in enhanced damages, the Company accrued $5.0 million in the first quarter of 2017. As the Company has made the payments, the accrual has been adjusted, and as of September 30, 2018, the loss contingency accrual was zero.
WesternGeco filed a second petition for writ of certiorari in the U.S. Supreme Court on February 17, 2017, appealing the lost profits issue again. The Company filed its response to WesternGeco’s second attempt to appeal to the Supreme Court the lost profits issue, raising both the substantive matters the Company addressed by opposing WesternGeco’s first petition, and also raisingadvancing a procedural argument that WesternGeco cannotcould not raise the same issue for a second time in a second petition for certiorari. On May 30, 2017, the Supreme Court called for the views of the U.S. Solicitor General regarding whether or not to grant certiorari. (The U.S. Supreme Court has discretion to hear, or not hear, WesternGeco’s appeal; granting WesternGeco’s request for a writ of certiorari would mean that the U.S. Supreme Court decided to hear WesternGeco’s appeal of the decision by the United States Court of Appeals for the Federal Circuit with respect to the lost profits issue.  If the Supreme Court agrees to hear WesternGeco’s appeal, the Company will contest WesternGeco’s appeal at the Supreme Court.  In such a case, it is possible that the Supreme Court could issue a ruling adverse to the Company.) The Company and WesternGeco each met with the Solicitor General’s office in late July 2017. TheOn December 6, 2017, the Solicitor General is expectedfiled its brief, and took the position that the Supreme Court ought to issue its briefgrant certiorari. On January 12, 2018, the Supreme Court granted certiorari as to whether the Court of Appeals erred in holding that lost profits arising from use of prohibited combinations occurring outside of the United States are categorically unavailable in cases where patent infringement is proven under 35 U.S.C. § 271(f)(2) (the specific statute under which the Company was ultimately held to have infringed WesternGeco’s patents and upon which the District Court and Court of Appeals relied in entering their final rulings).
The Supreme Court should grant certiorari nearheard oral arguments on April 16, 2018. At oral arguments, the endCompany argued that the Court of 2017 or the beginning of 2018, although there is no deadline forAppeals’ decision that eliminated lost profits ought to be affirmed. WesternGeco and the Solicitor General argued that the Court of Appeals’ decision that eliminated lost profits ought to be reversed.
On June 22, 2018, the Supreme Court reversed the judgment of the Court of Appeals, held that the award of lost profits to WesternGeco by the District Court was a permissible application of Section 284 of the Patent Act, and remanded the case back to the Circuit Court for further proceedings consistent with its (the Supreme Court’s) opinion. On July 24, 2018, the Supreme Court issued the judgment that returned the case to the Court of Appeals.
At the Court of Appeals, in the case leading up to the Supreme Court, the Company presented multiple arguments as to why the District Court’s award of lost profits was improper. The lost profits damages awarded by the District Court were based on the use of the Company’s products by our customers outside of the United States. The Company argued at the Court of Appeals, and at the Supreme Court, that, as a matter of law, WesternGeco cannot recoup lost profits for the overseas use of the Company’s products. This issue, decided in favor of WesternGeco in the recent Supreme Court opinion, was the only issue reached by the Supreme Court in that decision.
The Company also argued in the Court of Appeals that, under the jury instructions given in our case, the jury was required to find that the Company had been a direct competitor of WesternGeco in the survey markets where WesternGeco lost profits in order for WesternGeco to recoup them. Because the Court of Appeals ruled in favor of the Company on the first argument, and overturned the award of lost profits on that basis, the Court of Appeals did not rule on the Company’s “direct competitor” argument, and that argument was not presented to the Supreme Court for review. Thus, while the Supreme Court overturned the Court of Appeals’ decision that WesternGeco should not be allowed to recover foreign lost profits under the Patent Act, the Supreme Court did not order the Company to pay any amount with respect to lost profits, but rather remanded the case back to the Court of Appeals for further consideration of whether lost profits are payable by the Company in this case.
On July 25, 2018, the Company filed a motion for leave to file supplemental briefing in the Court of Appeals, and concurrently, filed a brief arguing that the judgment of the District Court as to both lost profits and reasonable royalties should be vacated, and that the case should be remanded to the District Court for a new determination on damages. On July 27, 2018, the Court of Appeals vacated its brief.September 21, 2016 judgment with respect to damages, and ordered WesternGeco and the Company to submit supplemental briefing on what relief is appropriate in light of the Supreme Court’s decision. This order rendered the Company’s motion for leave to submit briefing moot, and, accordingly, the Court of Appeals denied the Company’s motion as moot. The Company and WesternGeco each submitted briefing in accordance with the Court of Appeals’ order (with the last brief being filed with the Court of Appeals on September 7, 2018).
    

Other proceedings may have an impact on WesternGeco’s ability to recover lost profits damages and reasonable royalties even if the Company does not prevail on the “direct competitor” argument in the Court of Appeals, and were addressed, along with the direct competitor argument, in the parties’ briefing to the Court of Appeals (further described below). In particular, the Company was a party to a challenge to the validity of several of WesternGeco’s patent claims by means of an Inter Partes Review (“IPR”) with the Patent Trial and Appeal Board (“PTAB”). While the above-described lawsuit was pending on appeal, the PTAB invalidated four of the six patent claims that formed the basis for the jury verdict in the lawsuit. WesternGeco appealed that decision to the Court of Appeals, which heard the Company’s and WesternGeco’s arguments on January 23, 2018. The Court of Appeals affirmed the PTAB’s invalidation of the patents on May 7, 2018, and on July 16, 2018, the Court of Appeals denied WesternGeco’s petition for a panel rehearing and a rehearing en banc. This decision by the Court of Appeals may provide a separate ground for reducing or vacating any lost-profits or reasonable royalty award in the lawsuit.
WesternGeco argued, in its pending briefs before the Court of Appeals, that the only issue that remains to be decided is whether lost profits are unavailable to WesternGeco due to the Company’s “direct competitor” argument, and argued that the invalidation of four of its six patent claims by the Court of Appeals (which invalidation WesternGeco intends to appeal to the Supreme Court) should have no effect on lost profits or on the royalty award already paid by the Company. WesternGeco also argued that lost profits should be available notwithstanding the Company’s “direct competitor” argument.
The Company argued that lost profits are not available on the basis of the “direct competitor” argument, that the Court of Appeals’ affirmation that four of the six patent claims at issue are invalid has a preclusive effect on WesternGeco’s damages claims, and that the Court of Appeals should order a new trial as to the royalty damages already paid by ION. The Company argued, in the alternative, that if the Court of Appeals does not find the Company’s “direct competitor” argument persuasive, the Court of Appeals should nonetheless vacate the District Court’s award of royalty damages and lost profits damages and order a new trial as to both royalty damages and lost profits.
On October 19, 2018, the Court of Appeals scheduled oral arguments for the issues raised by the Company and WesternGeco in their briefs pending before that court. Oral arguments are scheduled to take place on November 16, 2018.
The Company may not ultimately prevail in any of the appeals processes noted above and the Company could be required to pay some or all of the lost profits that were awarded by the District Court if the judgment of the District Court is upheld by the Court of Appeals on remand, or if a new trial is granted and a new judgment issues. The Company’s assessment that it does not have a loss contingency may change in the future due to developments at the Supreme Court, Court of Appeals, or District Court, and other events, such as changes in applicable law, and such reassessment could lead to the determination that an additional loss contingency is probable, which could have a material effect on the Company’s business, financial condition and results of operations. The Company’s assessments disclosed in this Quarterly Report on Form 10-Q or elsewhere are based on currently available information and involve elements of judgment and significant uncertainties.
Other Litigation
The Company has been named in various other lawsuits or threatened actions that are incidental to its ordinary business. Litigation is inherently unpredictable. Any claims against the Company, whether meritorious or not, could be time-consuming, cause the Company to incur costs and expenses, require significant amounts of management time and result in the diversion of significant operational resources.

In the first quarter 2017, the Company adopted ASU 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting," that changed how the Company accounts for certain aspects of share-based payments to employees. The Company is required to recognize the income tax effects of awards in the statement of income when the awards vest or are settled. The guidance on employers’ accounting for an employee’s use of shares to satisfy the employer’s statutory income tax withholding obligation and for forfeitures is changed and now requires companies to present excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity. There was no impact of adoption of ASU 2016-09 on net income, basic and diluted earnings per share, deferred tax assets or net cash from operations.
Stock Repurchase Program
On November 4, 2015, the Company’s board of directors approved a stock repurchase program authorizing a Company stock repurchase, from time to time from November 10, 2015, through November 10, 2017, up to $25 million in shares of the Company’s outstanding common stock. The stock repurchase program may be implemented through open market repurchases or privately negotiated transactions, at management’s discretion. The actual timing, number and value of shares repurchased under the program will be determined by management at its discretion and will depend on a number of factors including the market price of the shares of our common stock and general market and economic conditions, applicable legal requirements and compliance with the terms of our outstanding indebtedness. The repurchase program does not obligate the Company to acquire any particular amount of common stock and may be modified or suspended at any time and could be terminated prior to completion. As of September 30, 2017, the Company had repurchased $3.0 million or 451,792 shares of its common stock under the repurchase program at an average price per share of $6.41. The Company does not expect to repurchase any additional shares prior to the expiration of the program on November 10, 2017.
(13)    Recent Accounting Pronouncements
Revenue Recognition — In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued new accounting guidance for recognition of revenue. In August 2015, the FASB issued guidance deferring the effective date to years beginning after December 15, 2017, and interim periods within those years. This new guidance replaces virtually all existing U.S. GAAP and IFRS guidance on revenue recognition. The underlying principle is that the entity will recognize revenue to depict the transfer of goods and services to customers at an amount that the entity expects to be entitled to in the exchange of goods and services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers.
The Company currently expects to use the modified retrospective adoption method effective January 1, 2018. While the Company continues to finalize its assessment regarding how the implementation of this new guidance may affect the Company’s New Venture group’s financial position or results of operations, no material impact is currently expected. The Company does not expect the adoption of ASC 606 to have a material impact on its consolidated balance sheets or consolidated statement of operations for its Imaging Services group, Devices group, Optimization Software & Services group or its Ocean Bottom Seismic Services segment. The Company has put in place an implementation team to review contracts subject to the new revenue standard, provide trainings and work with third party specialists to assist in the evaluation. The implementation team continues to review contracts and monitor the potential impact to the Company’s financial position or results of operations.
In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” which introduces the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. The guidance will be effective for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years with early adoption permitted. The Company currently expects that the adoption of ASU 2016-02 may have a material impact related to its facility operating leases on its consolidated financial statements, and continues to evaluate the impact of vessel leases in the Company’s Ocean Bottom Seismic Services segment.
In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230), Restricted Cash (a consensus of the FASB Emerging Issues Task Force) (ASU 2016-18),” that will require entities to show changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. When cash, cash equivalents, restricted cash and restricted cash equivalents are presented in more than one line item on the balance sheet, a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet is required. The guidance will be effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted. The Company does not currently expect the adoption of ASU 2016-18 to have a material impact on its consolidated financial statements.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Executive Summary
Our Business
In this Form 10-Q, “ION Geophysical,” “ION,” “the company” (or, “the Company”), “we,” “our,” “ours” and “us” refer to ION Geophysical Corporation and its consolidated subsidiaries, except where the context otherwise requires or as otherwise indicated.
The information contained in this Quarterly Report on Form 10-Q contains references to trademarks, service marks and registered marks of ION and our subsidiaries, as indicated. Except where stated otherwise or unless the context otherwise requires, the terms “VectorSeis,” “Orca,” “WiBand,” and “4Sea” refer to VECTORSEIS®, ORCA®, WiBand® and 4Sea® registered marks owned by ION, and the terms “Marlin” and “Gator,” refers to the Marlin™ and GATOR™, trademarks owned by ION.
We provideLeveraging innovative technologies, ION creates value through data capture, analysis and optimization to enhance critical decision-making abilities and returns. ION’s offerings are focused on improving E&P decision-making, enhancing reservoir management and optimizing offshore operations. While ION’s traditional focus for its cutting-edge technology has been on the E&P industry, we are now broadening and diversifying our business into relevant adjacent markets such as offshore logistics, military and marine robotics.
Our geoscience technology, services and solutions to the global oil and gas industry. Our offerings are designed to allowenable oil and gas companies to obtain higher resolution images of the Earth’s subsurface to reduce their risk and optimize assetsvalue across the exploration and production lifecycle. Seismic imaging plays a fundamental role in hydrocarbon exploration and reservoir development by delineating structures and rock types and fluid locations in the subsurface. The high resolution images of the Earth’s subsurface can be used to reduce uncertainty associated with identifying sources of hydrocarbons and pinpointing drilling locations for wells, which can be costly and risky.
We acquire and process seismic data on both a proprietary and multi-client basis. The multi-client seismic surveys for our data library business are pre-funded or underwritten in part by our customers, and with the exception of our ocean bottom seismic (“OBS”) data acquisition company, OceanGeo B.V. (“OceanGeo”), we utilize an “asset lite”asset light strategy by contracting with third partythird-party seismic data acquisition companies to acquire the seismic data, all of which is intended to minimize our risk exposure. We serve customers in most major energy producing regions of the world from offices strategically located across six continents.
We provide our services and products through three business segments: E&P Technology & Services, Operations Optimization (formerly referred to as E&P Operations OptimizationOptimization) and Ocean Bottom Integrated Technologies (formerly referred to as Ocean Bottom Seismic Services.Services). In addition, we have a 49% ownership interest in our INOVA Geophysical Equipment Limited joint venture (“INOVA Geophysical,”Geophysical” or “INOVA”). As of December 31, 2014, we wrote down our investment in INOVA Geophysical to zero, and therefore no longer record our share of losses in the joint venture.
For decades,50 years, we have provided innovative seismic data acquisition technology, such as multicomponentmulti-component imaging with VectorSeis products, the ability to record seismic data from basins below ice, and cableless seismicdata acquisition techniques. The advanced technologies we currently offer include our Orca and Gator command and control software systems, WiBand broadbandFull Waveform Inversion (“FWI”) data processing technology, our OBSocean bottom seismic (“OBS”) acquisition systems, and other technologies, each of which is designed to deliver improvements in both image quality, andsafety and/or productivity. In 2015, we introduced our Marlin solution for optimizing simultaneousto optimize operations offshore. OurIn 2017, we introduced our new OBS technology,fully integrated nodal system, 4Sea, openswhich is designed to deliver a much larger market due to the system’s increased flexibilitystep change in economics, QHSE performance and efficiency. We introduced this system to all major consumers of OBS projects at the European Association of Geophysical Contractors annual meetingfinal image delivery time, creating more value for clients by providing data in June 2017time for critical reservoir decisions, such as determining drilling locations and it was extremely well received. We have worked quietly for over three years to develop this system and believe it will be extremely competitive.informing enhanced recovery techniques.
We have approximately 500 patents and pending patent applications in various countries around the world. Approximately 49%44% of our employees are in technical roles and over 25%22% of our employees have advanced degrees.
E&P Technology & Services. Our E&P Technology & Services segment provides three distinct service activities that often work together.
Our E&P Technology & Services segment focuses on providingcreates digital data assets and delivers services to help E&P companies to make better decisions,improve decision-making, reduce risk and maximize value. For example, E&P Technology & Services provides information to better understand new frontiers imaging services to better understandor complex subsurface geologies, and consulting serviceshow to maximize portfolio value, or how to optimize asset decisions and portfolios and to help host governments maximize assets by supporting a license round etc.success and acreage values.

Our Ventures servicesgroup leverages the world-class geoscience skills of both the Imaging Services and E&P Advisors groups to create global digital data assets that are designedlicensed to multiple E&P companies to optimize their investment decisions. The global data library consists of over 614,000 km of 2-D and over 223,000 sq. km of 3-D multi-client seismic data in virtually all major offshore petroleum provinces. Ventures provides services to manage the entire seismic process for multi-client or proprietary surveys, from survey planning and design to data acquisition and management, to final subsurface imaging and reservoir characterization. Our Ventures group focusesWe focus on the technologically intensive components of the image development process, such as survey planning and design, and data processing and interpretation, while outsourcing the logisticsasset-intensive components (such as field acquisition) to experienced seismic and other geophysical contractors. Since 2002, our basin exploration seismic data programs have resulted in a substantial data library that covers significant portions of many basins in the world, including offshore East and West Africa, South America, the Arctic, the Gulf of Mexico and Australia.

Our Imaging Services group offers data processing and imaging services designed to help ourmaximize image quality, helping E&P customerscompanies reduce exploration and production risk, evaluate and develop reservoirs, and increase production. Imaging Services develops a series of subsurface images by applying its processing technology to data owned or licensed by its customers.

INOVA Geophysical. Historically, we conducted our land seismic equipment business through INOVA Geophysical, which is a joint venture with BGP Inc. (“BGP”). BGP is a subsidiary of China National Petroleum Corporation, and is generally regarded as the world’s largest land geophysical service contractor. BGP owns a 51% equity interest in INOVA Geophysical, and we own the remaining 49% interest. INOVA manufactures cable-based and cableless data acquisition systems, digital sensors, vibroseis vehicles (i.e., vibrator trucks) and source controllers for land seismic surveys. We wrote our investment in INOVA down to zero as of December 31, 2014.
Public Equity Offering and Retirement of Debt
On February 21, 2018, we announced our successful completion of a public equity offering to begin delevering our business.  As part of the equity offering, we sold 1,820,000 of our common shares at a price of $27.50 per share, and issued warrants to purchase an additional 1,820,000 shares of our common stock. The warrants have an exercise price of $33.60 per share are immediately exercisable and expire in March 2019.  If the warrants are exercised in full, we would receive additional proceeds of $61.2 million excluding underwriter fees and other transaction expenses. Our net cash flows for the first quarter of

2018 reflect the $47.0 million of net proceeds received from our equity offering, a portion of which were used to retire the $28.5 million of Third Lien Notes ahead of their scheduled maturity in May 2018. We also repaid the $10.0 million of outstanding indebtedness under our Credit Facility during the first quarter 2018. As a result of our first quarter 2018 debt repayments, we have $1.3 million of current debt remaining on our balance sheet at September 30, 2018, and our remaining long-term debt obligation is the $120.6 million of our indebtedness under our Second Lien Notes due in December 2021.
Macroeconomic Conditions
Demand for our services and products is cyclical and dependent upon activity levels in the oil and gas industry, particularly our customers’ willingness to invest capital in the exploration for oil and natural gas. Our customers’ capital spending programs are generally based on their outlook for near-term and long-term commodity prices, economic growth, commodityresource supply and demand, and estimates of resource production. Following an unprecedented two years of double-digit declines, third-partycommodity prices. Third-party reports now indicate that global exploration and production spending is expected to increase 8% in 2018, 15% to 20% in North American and 5% internationally. This is an improvement from the 4% growth in 2017 with further increasesthat was preceded by two years of 4%double-digit declines. In addition, this is the first time in 2018.three years that international spending is expected to increase where our offerings are more relevant.
InShale production has dominated activity during the past few years,downturn due to its competitive break-even prices and short payback period compared to conventional exploration. However, longer-term, there’s a general consensus that investment in conventional resources is required to meet longer-term demand in the next decade. We’re starting to see increasing pressure for a resumption in offshore investment and exploration activity to replace reserves.

Crude oil prices have beencan be volatile due to global economic uncertainties.a number of factors. Significant downward oil price volatility began late in 2014 and reached a low average of $33 per barrel in early 2016. The material decrease in crude oil prices can be attributed principally to high levels of global crude oil inventories resulting from significant production growth in the U.S. shale plays and the strengthening of the U.S. dollar relative to other foreign currencies, and the Organization of Petroleum Exporting Countries (“OPEC”) increasing its production, causing a global supply and demand imbalance for crude oil. In late November 2016, OPEC and other non-OPEC participants, such as Russia, reached an agreement to cut their oil production. In late June 2018, Saudi Arabia and Russia agreed to add oil to the global market, while effectively keeping OPEC and some non-OPEC states in full conformity with the late 2016 pact to curb output. In September 2018, Saudi Arabia and Russia increased output as agreed. With the increase in worldwide demand, recent extension of the OPEC production cuts through December 2018, partially offset by the agreement with Saudi Arabia and Russia to compensate for lost capacity in Iran and Venezuela, global crude oil supply and demand is essentially in equilibrium, stabilizing prices and capital expenditure.
The prices for Intercontinental Exchange Brent (“Brent”) and West Texas Intermediate (“WTI”) crude oil remained steady atincreased to an average of $52$72 per barrel and $49 per barrel, respectively, in the first nine months of 2017.2018. This represents ana $19 per barrel improvement over the average crude oil prices for the full year 20162017 of $43 per barrel and $42 per barrel, respectively.$53. This price increase was due to multiple factors, including successfulrobust global demand and sustained OPEC production cuts, andthe combination of which resulted in net inventory crude draws whichthat reduced the currentoverall crude surplus. Many analysts currently expectThe EIA forecasts the Brent crude oil spot price to remain close to the current price for the remainder of 2017.will average $74 per barrel in 2018 and $75 per barrel in 2019. Energy reform in Mexico and a bill passed in Brazil that eliminatesopened up the requirementcountries for Petrobras to participate in every presalt offshore block,increased international investment, in conjunction with the stability of oil prices, has resulted in increased investment in those areas. In addition, price stability has encouraged North American drillers to increase shale production. During the first nine months of 2017, U.S. producers added 282 rigs bringing the total U.S. rig count 940, a 43% increase during the first nine months of 2017, compared to 658 rigs at the end of 2016.

Given the historical volatility of crude prices, there is a continued risk that if prices start to decline again due to high levels of crude oil production, there is a potential for slowing growth rates in various global regions and/or for ongoing supply/demand imbalances.

Prices for natural gas in the U.S. averaged $3.01 per mmBtu in the first nine months of 2017, compared to $2.40 per mmBtu for the full year 2016, and $4.57 per mmBtu for the first nine months of 2014. As a result of natural gas production growth outpacing demand in the U.S., natural gas prices continue to be weak relative to prices experienced from 2006 through 2008. If the supply of natural gas from conventional and unconventional production or associated natural gas production from oil wells continues to exceed demand, prices for natural gas may remain depressed for an extended period of time.
After a period of growth in exploration activities and associated spending leading up to the end of 2014, many E&P companies shifted their focus to production activities, away from exploration, as the continued decline in oil and gas prices resulted in decreased revenues, prompting cost reduction initiatives across the industry. From the end of 2014 through 2016, E&P companies decreased spending on exploration and reportedly focused their spending on critical production requirements and existing commitments. We believe this was due to several factors, but primarily because operational cash flows of E&P companies were no longer sufficient to cover capital expenditures while continuing to pay cash dividends to shareholders. E&P companies relied on asset sales and debt financings to fund capital requirements amid demands for greater returns to shareholders. The combination of these factors placed many E&P companies in a position where they were unable to cover both their capital expenditure budgets and targeted cash returns to shareholders. As a result, E&P companies dramatically cut spending, with exploration spending receiving the largest reductions and seismic spending being one of the most discretionary parts of their exploration budgets. As a result of this industry downturn, many customers experienced a significant reduction in their liquidity with challenges accessing the capital markets. Several exploration and production companies declared bankruptcy, or exchanged equity for the forgiveness of debt, while others were forced to sell assets in an effort to preserve liquidity. However, over the past 12 months, access to the capital and debt markets improved significantly for certain of these customers.
During 2017 and into 2018, E&P spending is expectedhas continued to rebound and increase followingin 2018 over 2017, which was preceded by two successive years of double digit declines as commodity prices are forecasted to remain more stable.declines. This positive trend in E&P spending, aided by favorable macroeconomic conditions, has resulted in increased E&P revenues during the first nine months of 2017.in 2017 and 2018. If the global supplyproduction of oil decreases due to reduced capital investment by E&P companies, government instability occurs in a major oil-producing nation, or energy demand increases in the U.S. or in countries such as China and India,materially exceeds forecasts, the recovery in WTI and Brent crude oil prices could continue to improve. If commodity prices do not continue to improve, or if they start to deteriorate again, demand for our services and products could decline.
Impact to Our Business
DuringWe are seeing signs of increasing activity in our business, primarily due to the strategic shift we made to move our offerings closer to the reservoir and the associated continued success of our 3-D multi-client programs as well as clients starting to renew interest in conventional reserve replacement and offshore exploration. Generally, our revenue and EBITDA generation increases sequentially throughout the year as customers set budgets in the first nine months of 2017, we saw renewed customer interestquarter, firm up plans throughout the year, and spend excess budget in underwriting of our new venture programs as oil companies were able to right-size their expenditures to current oil prices and generate profits for the first time in nine quarters. During the first nine months of 2017, revenues increased by 2% as compared to the first nine months of 2016. During the first nine months of 2016, our OBS Services segment completed a survey offshore Nigeria, since which the crew has remained idle. Excluding the OBS Services revenue from one year ago, revenues were up 38%.fourth quarter. Investments in our multi-client data library are dependent upon the timing of our new venture projects and the availability of underwriting by our customers. We continue to maintain high standards for the underwriting of any new projects, and have sanctioned several new programs in the current year that were originally planned to occur during 2016.projects. Our “asset lite”asset light strategy enables us to scale our business to avoidmarket conditions avoiding significant fixed costs and maintaining flexibility to remain financially flexible as we manage the timing and levelsamount of our capital expenditures.
In our E&P Technology & Services segment, new venture revenues experienced significant declines compared to the third quarter 2017, while data library revenues increased. In the current disciplined spending environment, clients wait to purchase data until a formal public announcement has been made by the government. Delays in license round announcements can materially impact the timing of sales in areas where our new venture revenues increased related to progressprograms are underway. Our under performance was driven by the continued delay of the Panama license round announcement, the deferment of new E&P investments in Mexico until there is more policy clarity from the newly elected administration that takes office in December and new salesthe continued focus on our 3-D reimaging programs, as well as 2-D new venture programs that met our conservative underwriting standards, this increase in new venture revenues was partially offset by a decline in data library sales.cash preservation within E&P companies restricting exploration spending. We invested $16.6$19.9 million in our multi-client data library during the first three quarters of 20172018 and we expect investments in our multi-client data library to be in a range of $20$30 million to $30$35 million for 2017,2018, compared to the $14.9$23.7 million invested in 2016.2017.
As of September 30, 2017,2018, our E&P Technology & Services segment backlog, which consists of commitments for (i) data processing work, and (ii) both multi-client new venture projects (both multi-client and proprietary projectsproprietary) by our Ventures group underwritten by our customers and (iii) E&P Advisor projects, was $39.6$33.1 million compared to $33.9$39.2 million at December 31, 20162017 and $29.9$39.6 million at September 30, 2016.2017. The growthmajority of our backlog was duerelates to ongoing activityour 3-D multi-client reimaging programs offshore Brazil and to a lesser extent from new 2-D multi-client programs in Canada and Africa and our 3-D multi-client programs in Mexico as well as activity related to several newly sanctioned programs.and our proprietary Imaging Services and E&P Advisors work. We anticipate that the majority of our backlog will be recognized as revenue over the next six months.
For the first nine months of 2017,We embarked on a new strategy for our Ocean Bottom SeismicIntegrated Technologies segment at the end of 2017 that will include licensing 4Sea individual components. Such licensing will be recognized through the relevant segment, either E&P Technology and Services segment continuesor Operations Optimization. If a customer licenses the right to manufacture and use the fully integrated system or we undertake OBS acquisition projects that meet our long-term risk and return thresholds, those activities will be affected by E&P companies delaying or canceling decisionsrecognized in this segment. During 2017, our existing ocean bottom vessel leases expired, consistent with our asset light strategy. We continue to commit capital to OBS projects, while our crew has remained idle since completion of a survey offshore Nigeria in the third quarter 2016. Despite political issues and uncertainty, we see significant long-term potential for OceanGeo and our technologies to improve OBS productivity,safety, efficiency and data quality, and we expect demand for OBS surveys to increase.continue increasing.
OurWithin the Operations Optimization segment, increases in Optimization Software & Services revenues was due to continued increase in subscription-based software revenues and hardware sales of its Gator ocean bottom command and control software. Devices revenues continue to be impacted by reduced towed streamer seismic contractor customers are also experiencing weakened demand due to the reduction in seismic spending by their oil company customers.activity. Since early 2014, seismic contractors have taken approximately 3541 seismic vessels, or about 29%34% of the fleet, out of the market, contributing to slightly lower E&P Operations Optimization segment sales year-over-year.

We continue to monitorhowever, in 2018 the global economy,trend of removing vessels from the demand for crude oil and natural gas and the resulting impact on the capital spending plans and operations of our E&P customers to plan our business. During late 2014 and continuing through mid-2016, we reduced our workforce by over 60%, and closed selected facilities. Our workforcemarket has since stabilized. These actions are expected to result in annualized cash savings of approximately $95 million which we began to fully realize in 2017. We remain confident that, despite current marketplace challenges described above, we have positioned ourselves to take advantage of the next E&P market upturn by reducing our cost structure to reflect our revenue base, shifting our focus more toward E&P solutions and less on equipment sales, and by diversifying our offerings across the E&P lifecycle.flattened.
It is our view that technologies that provide a competitive advantage through improved imaging, lower costs, higher productivity, or enhanced safety will continue to be valued in our marketplace. We believe that our newest technologies, such as Marlin and 4Sea, will continue to attract customer interest, because these technologies are designed to deliver those desirable qualities.attributes.
WesternGeco Litigation

A more in depth treatment of the WesternGeco Litigationlitigation and related proceedings is set forth above in Footnote 6 “8 Litigation“Litigation” of Footnotes to Unaudited Condensed Financial StatementsStatements.. As noted in such Footnote, on July 2, 2015, the United States Court of Appeals for the Federal Circuit in Washington, D.C. (the “Court of Appeals”) reversed in part the Final

Judgment of the District Court’s judgment,Court, holding the District Court erred by including lost profits in the Final Judgment. Lost profits were $93.4 million and prejudgment interest on the lost profits was approximately $10.9 million of the $123.8 million Final Judgment. Pre-judgment interest on the lost profits portion will be treated in the same way as the lost profits. Post-judgment interest will likewise be treated in the same fashion. On July 29, 2015, WesternGeco filed a petition for rehearing en banc before the Court of Appeals. On October 30, 2015 the Court of Appeals denied WesternGeco’s petition for rehearing en banc.
As previously disclosed, we had taken a loss contingency accrual of $123.8 million. As a result of the reversal by the Court of Appeals, as of June 30, 2015, we reduced our loss contingency accrual to $22.0 million.
On February 26, 2016, WesternGeco filed a petition for writ of certiorari by the Supreme Court. We filed our response on April 27, 2016. Subsequently, on June 20, 2016, the Supreme Court refused to disturbvacated the Court of AppealsAppeals’ ruling finding noalthough it did not address the lost profits as a matter of law.  Separately,question at that time. Rather, in light of the changes in case law regarding the standard of proof for willfulness in the Halo and Stryker cases, the Supreme Court indicated that the case should be remanded to the Federal CircuitCourt of Appeals for a determination of whether or not the willfulness determination by the District Court was appropriate.
On October 14, 2016, the Court of Appeals issued a mandate returning the case to the District Court for consideration of whether or not additional damages for willfulness were appropriate.
On November 14, 2016, the District Court issued an order reducing the amount of the appeal bond from $120.0 million to $65.0 million, ordered the sureties to pay principal and interest on the royalty damages previously awarded and declined to issue a final judgment until after consideration of whether enhanced damages related tofor willfulness shouldwould be awarded in the case.awarded. While we did not agree with the unusual decision by the District Court ordering payment of the royalty damages and interest without a final judgment, we paid the $20.8 million due pursuant to the order to WesternGeco on November 25, 2016.2016, at which point we reduced our loss contingency accrual to zero.
On March 14, 2017, the District Court held a hearing on whether or not additional damages for willfulness would be payable. The Judge found that ION’s infringement was willful, based on his perception that ION did not adequately investigate the scope of the patent,patents, and ION’s conduct during trial. However, in his ruling at the hearing, he limited enhanced damages to $5.0 million because it was a “close case,” there was no evidence of copying, and ION was simply acting as a competitor in a capitalist marketplace. The District Court also ordered the appeal bond to be released and discharged. The Court’s findings and ruling were memorialized in an order issued on May 16, 2017. On June 30, 2017, WesternGeco and weION jointly agreed that neither party would appeal the District Court's award of $5.0 million in enhanced damages. The parties also agreed that the $5.0 million would be paid over the course of 12 months with $1.25 million being paid in two installments of $0.625 million in 2017 and the remaining $3.75 million being paid in three quarterly payments of $1.25 million beginning January 1, 2018.months. This agreement was memorialized by the court in an order issued on July 26, 2017. Upon assessment of the $5.0 million in enhanced damages, we accrued $5.0 million in the first quarter of 2017. As we have made the payments, the accrual has been adjusted, and as of June 30, 2018, the loss contingency accrual was zero.
WesternGeco filed a second petition for writ of certiorari in the U.S. Supreme Court on February 17, 2017, appealing the lost profits issue again. We filed our response to WesternGeco’s second attempt to appeal to the Supreme Court the lost profits issue, raising both the substantive matters we addressed by opposing WesternGeco’s first petition, and also raisingadvancing a procedural argument that WesternGeco cannotcould not raise the same issue for a second time in a second petition for certiorari. On May 30, 2017, the Supreme Court called for the views of the U.S. Solicitor General regarding whether or not to grant certiorari. (The U.S. Supreme Court has discretion to hear, or not hear, WesternGeco’s appeal; granting WesternGeco’s request for a writ of certiorari would mean that the U.S. Supreme Court decided to hear WesternGeco’s appeal of the decision by the United States Court of Appeals for the Federal Circuit with respect to the lost profits issue.  If the Supreme Court agrees to hear WesternGeco’s appeal, we will contest WesternGeco’s appeal at the Supreme Court.  In such a case, it is possible that the Supreme Court could issue a ruling adverse to ION.) WeION and WesternGeco each met with the Solicitor General’s office in late July, 2017. TheOn December 6, 2017, the Solicitor General is expectedfiled its brief, and took the position that the Supreme Court ought to issue its briefgrant certiorari. On January 12, 2018, the Supreme Court granted certiorari as to whether the Court of Appeals erred in holding that lost profits arising from use of prohibited combinations occurring outside of the United States are categorically unavailable in cases where patent infringement is proven under 35 U.S.C. § 271(f)(2) (the specific statute under which we were ultimately held to have infringed WesternGeco’s patents and upon which the District Court and the Court of Appeals relied in entering their final rulings).
The Supreme Court should grant certiorari nearheard oral arguments on April 16, 2018. At oral arguments, we argued that the endCourt of 2017 or the beginning of 2018, although there is no deadline forAppeals’ decision that eliminated lost profits ought to be affirmed. WesternGeco and the Solicitor General argued that the Court of Appeals’ decision that eliminated lost profits ought to be reversed.
On June 22, 2018, the Supreme Court reversed the judgment of the Court of Appeals, held that the award of lost profits to WesternGeco by the District Court was a permissible application of Section 284 of the Patent Act, and remanded the case back to the Circuit Court for further proceedings consistent with its (the Supreme Court’s) opinion. On July 24, 2018, the Supreme Court issued the judgment that returned the case to the Court of Appeals.
At the Court of Appeals, in the case leading up to the Supreme Court, we presented multiple arguments as to why the District Court’s award of lost profits was improper. The lost profits damages awarded by the District Court were based on the use of our products by our customers outside of the United States. We argued at the Court of Appeals, and at the Supreme Court, that, as a matter of law, WesternGeco cannot recoup lost profits for the overseas use of our products. This issue, such an opinion.decided in favor of WesternGeco in the recent Supreme Court opinion, was the only issue reached by the Supreme Court in that decision.
    

We also argued in the Court of Appeals that, under the jury instructions given in our case, the jury was required to find that we had been a direct competitor of WesternGeco in the survey markets where WesternGeco lost profits in order for WesternGeco to recoup them. Because the Court of Appeals ruled in favor of us on the first argument, and overturned the award of lost profits on that basis, the Court of Appeals did not rule on our “direct competitor” argument, and that argument was not presented to the Supreme Court for review. Thus, while the Supreme Court overturned the Court of Appeals’ decision that WesternGeco should not be allowed to recover foreign lost profits under the Patent Act, the Supreme Court did not order us to pay any amount with respect to lost profits, but rather remanded the case back to the Court of Appeals for further consideration of whether lost profits are payable by us in this case.
On July 25, 2018, we filed a motion for leave to file supplemental briefing in the Court of Appeals, and concurrently, filed a brief arguing that the judgment of the District Court as to both lost profits and reasonable royalties should be vacated, and that the case should be remanded to the District Court for a new determination on damages. On July 27, 2018, the Court of Appeals vacated its September 21, 2016 judgment with respect to damages, and ordered WesternGeco and Ion to submit supplemental briefing on what relief is appropriate in light of the Supreme Court’s decision. This order rendered our motion for leave to submit briefing moot, and, accordingly, the Court of Appeals denied our motion as moot. ION and WesternGeco each submitted briefing in accordance with the Court of Appeals’ order (with the last brief being filed with the Court of Appeals on September 7, 2018).
Other proceedings may have an impact on WesternGeco’s ability to recover lost profits damages and reasonable royalties even if we do not prevail on the “direct competitor” argument in the Court of Appeals, and were addressed, along with the direct competitor argument, in the parties’ briefing to the Court of Appeals (further described below). In particular, we were a party to a challenge to the validity of several of WesternGeco’s patent claims by means of an Inter Partes Review (“IPR”) with the Patent Trial and Appeal Board (“PTAB”). While the above-described lawsuit was pending on appeal, the PTAB invalidated four of the six patent claims that formed the basis for the jury verdict in the lawsuit. WesternGeco appealed that decision to the Court of Appeals, which heard ION and WesternGeco’s arguments on January 23, 2018. The Court of Appeals affirmed the PTAB’s invalidation of the patents on May 7, 2018, and on July 16, 2018, the Court of Appeals denied WesternGeco’s petition for a panel rehearing and a rehearing en banc. This decision by the Court of Appeals may provide a separate ground for reducing or vacating any lost-profits or reasonable royalty award in the lawsuit.
WesternGeco argued, in its pending briefs before the Court of Appeals, that the only issue that remains to be decided is whether lost profits are unavailable to WesternGeco due to our “direct competitor” argument, and argued that the invalidation of four of its six patent claims by the Court of Appeals (which invalidation WesternGeco intends to appeal to the Supreme Court) should have no effect on lost profits or on the royalty award we already paid. WesternGeco also argued that lost profits should be available notwithstanding our “direct competitor” argument.
We argued that lost profits are not available on the basis of the “direct competitor” argument, that the Court of Appeals’ affirmation that four of the six patent claims at issue are invalid has a preclusive effect on WesternGeco’s damages claims, and that the Court of Appeals should order a new trial as to the royalty damages we already paid. We argued, in the alternative, that if the Court of Appeals does not find our “direct competitor” argument persuasive, the Court of Appeals should nonetheless vacate the District Court’s award of royalty damages and lost profits damages and order a new trial as to both royalty damages and lost profits.
On October 19, 2018, the Court of Appeals scheduled oral arguments for the issues we raised and WesternGeco in their briefs pending before that court. Oral arguments are scheduled to take place on November 16, 2018.
We may not ultimately prevail in any of the appeals processes noted above and we could be required to pay some or all of the lost profits that were awarded by the District Court if the judgment of the District Court is upheld by the Court of Appeals on remand, or if a new trial is granted and a new judgment issues. Our assessment that we do not have a loss contingency may change in the future due to developments at the Supreme Court, Court of Appeals, or District Court, and other events, such as changes in applicable law, and such reassessment could lead to the determination that an additional loss contingency is probable, which could have a material effect on our business, financial condition and results of operations. Our assessments disclosed in this Quarterly Report on Form 10-Q or elsewhere are based on currently available information and involve elements of judgment and significant uncertainties.

We intend that the following discussion of our financial condition and results of operations will provide information that will assist in understanding our consolidated financial statements, the changes in certain key items in those financial statements from period to period, and the primary factors that accounted for those changes. The financial results are reported in accordance with Generally Accepted Accounting Principles (“GAAP”). However, management believes that certain non-GAAP performance measures may provide users of this financial information, additional meaningful comparisons between current results and results in prior operating periods. One such non-GAAP financial measure is adjusted income (loss) from operations or adjusted net income (loss), which excludes certain charges or amounts. This adjusted income (loss) amount is not a measure of financial performance under GAAP. Accordingly, it should not be considered as a substitute for income (loss) from operations, net income (loss) or other income data prepared in accordance with GAAP.
For a discussion of factors that could impact our future operating results and financial condition, see (i) Item 1A. “Risk Factors” in our Annual Report on Form 10-K, as amended, for the year ended December 31, 20162017, and (ii) Item 1A. “Risk Factors” in Part II of this Form 10-Q.
Results of Operations
Three Months Ended September 30, 20172018 Compared to Three Months Ended September 30, 20162017
Our consolidated net revenues of $47.2 million for the three months ended September 30, 2018 (the “Current Quarter”) decreased by $13.9 million, or 23%, compared to total net revenues of $61.1 million for the three months ended September 30, 2017 (the “Current Quarter”) decreased by $17.5 million, or (22)%, compared to total net revenues of $78.6 million for the three months ended September 30, 2016 (the “Comparable Quarter”). Excluding the OBS Services revenues from the third quarter 2016; OBS Services crew was idle throughout 2017; all other segment revenues were up 26% compared to the third quarter 2016. Our overall gross margin was 49%35% in the Current Quarter, as compared to 40%49% in the Comparable Quarter. For the Current Quarter, our incomeloss from operations was $9.9$2.5 million, compared to a income of $11.99.9 million for the Comparable Quarter.
Net incomeloss for the Current Quarter was $4.9$7.5 million, or $0.41(0.54) per diluted share, compared to $1.7$4.9 million, or $0.14$0.41 per diluted share, for the Comparable Quarter. Excluding the impact of special items, as noted in the above table, adjusted net loss for the Current Quarter which includes OBS operations.was $7.3 million, or $(0.52) per share.
Net Revenues, Gross Profits and Gross Margins
E&P Technology & Services — Net revenues for the Current Quarter increaseddecreased by $16.1$15.8 million, or 44%30%, to $52.1$36.3 million, compared to $36.0$52.1 million for the Comparable Quarter. TheWithin the E&P Technology & Services segment, total multi-client revenues were $32.2 million, a decrease of 34%, with new venture revenues experiencing significant declines from the Comparable Quarter, partially offsetting the overall decline in new ventures was an increase in data library revenues, attributable to sales of the recently completed phase of the Brazil 3-D reimaging program, along with sales of 2-D data libraries in India. The decrease in multi-client revenues was primarily due todriven by the continued revenue from our 3-D multi-client reimaging programs offshore Mexico and Brazil, as well as revenues from new 2-D multi-client programs that have recently been launched. These increases were partially offset by a decline in our data library sales, primarily related to a significant one-time purchase by a customer in the third quarter 2016 that did not reoccur in the third quarter 2017, as well as a decrease in imaging services as a resultdelay of the shift we madePanama license round announcement, the deferment of new E&P investments in Mexico until there is more policy clarity from the newly elected administration that takes office in December and the continued focus on cash preservation within E&P companies restricting exploration spending. Imaging Services revenues were $4.1 million, a 20% increase. This increase was attributable to higher return multi-client new ventures programs.an increase in proprietary ocean bottom nodal imaging projects. The Current Quarter reflects a Gross profit of $12.1 million, representing a 33% gross margin, compared to a Gross profit of $28.5 million, representing a 55% gross margin, improving $15.6 million as compared to a gross profit of $12.9 million, which represented a 36%55% gross margin in the Comparable Quarter. These improvementsdeclines in gross profit and margin were due to the decrease in revenues noted above.
Operations Optimization — Total net revenues for the Current Quarter increased by $1.9 million, or 21% to $10.9 million, compared to $9.0 million for the Comparable Quarter. Optimization Software & Services net revenues for the Current Quarter increased by $1.7 million, or 45% to $5.5 million, compared to $3.8 million for the Comparable Quarter, primarily due to an increase in subscription-based software revenues and hardware sales of our Gator ocean bottom command and control system. Devices net revenues for the Current Quarter increased by $0.1 million, or 2%, to $5.4 million, which is fairly consistent compared to $5.3 million for the Comparable Quarter. The Current Quarter reflects a Gross profit of $5.7 million, representing a 53% gross margin, compared to a Gross profit of $4.1 million, representing a 45% gross margin for the Comparable Quarter. These increases in gross profit and margin were due to the increase in revenues and due to a mix of higher margin 3-D reimaging programs as noted above and our cost control initiatives implemented in 2014 and continued through 2016.
E&P Operations Optimization — Devices net revenues for the Current Quarter decreased by $3.4 million, or 39%, to $5.3 million, compared to $8.7 million for the Comparable Quarter. Revenues continue to be impacted by reduced activity by seismic contractors as numerous vessels have been taken out of service. Optimization Software & Services net revenues for the third quarter decreased by $0.1 million, or 3% to $3.8 million, compared to $3.9 million for the Comparable Quarter. Gross margin was 45% for the Current Quarter, compared to 54% for the Comparable Quarter. The decline in gross margin was due to a higher mix of lower margin sales in the current quarter.described above.

Liquidity and Capital Resources
Sources of Capital
As of September 30, 20172018, we had $40.2total liquidity of $72.8 million, consisting of $30.0 million of cash on hand and $12.1nothing drawn from our $42.8 million of undrawnavailable borrowing base availabilitycapacity under theour Credit Facility. Our cash requirements include working capital requirements and cash required for our debt service payments, multi-client seismic data acquisition activities and capital expenditures. As of September 30, 2017,2018, we had working capital of $(15.8) million, which includes a current liability of $28.5 million of Senior secured third-priority lien notes that are payable during the second quarter 2018, which we expect to pay at maturity using available liquidity.$(4.9) million. Working capital requirements are primarily driven by our investment in our multi-client data library ($16.619.9 million in the Current Period) and royalty payments for multi-client sales. Also, our headcount has traditionally been a significant driver of our working capital needs. As a significant portion of our business is involved in the planning, processing and interpretation of seismic data services, one of our largest investments is in our employees, which involvesrequires cash expenditures for their salaries, bonuses, payroll taxes and related compensation expenses. During late 2014expenses, typically in advance of related revenue billings and continuing through mid-2016, we reduced our workforce by over 60%, and closed selected facilities. Our workforce has since stabilized. These actions are expected to result in annualized cash savings of approximately $95 million which we began to fully realize in 2017.collections.
Our working capital requirements may change from time to time depending upon many factors, including our operating results and adjustments in our operating plan in response to industry conditions, competition and unexpected events. In recent years, our primary sources of funds have been cash flows generated from operations, existing cash balances, debt and equity issuances and borrowings under our revolving credit facilities.

(collectively,(the “Material U.S. Subsidiaries”), along with GX Geoscience Corporation, S. de R.L. de C.V., a limited liability company (Sociedad de Responsibilidad Limitada de Capital Variable) organized under the laws of Mexico, and a subsidiary of the Company (the “Mexican Subsidiary”), (the Material U.S. Subsidiaries and the Mexican Subsidiary are collectively, the “Subsidiary Borrowers”, together with ION Geophysical Corporation are the “Borrowers”) entered into a Revolving Credit, the financial institutions party thereto, as lenders, and Security Agreement with PNC Bank, National Association (“PNC”), as agent for the lenders, entered into that certain Third Amendment and Joinder to Revolving Credit and Security Agreement (the “Original Credit Agreement”“Third Amendment”), which wasamending the Revolving Credit and Security Agreement, dated as of August 22, 2014 (as previously amended by the First Amendment to Revolving Credit and Security Agreement, indated as of August 4, 2015 (the “First Amendment”) and the Second Amendment to Revolving Credit and Security Agreement, indated as of April 28, 2016, (the “Second Amendment”; the Original“Credit Agreement”). The Credit Agreement, as amended by the First Amendment, and the Second Amendment and the Third Amendment is herein called the “Credit Facility”). The Third Amendment amends the Credit Agreement to, among other things:
The Credit Facility is available to provide forextend the Borrowers’ general corporate needs, including working capital requirements, capital expenditures, surety deposits and acquisition financing. The maximum amountmaturity date of the revolving line of credit under the Credit Facility isby approximately four years (from August 22, 2019 to August 16, 2023), subject to our retirement or extension of the lessermaturity date of its Second Lien Notes, as defined below, which matures on December 15, 2021;
increase the maximum revolver amount by $10.0 million (from $40.0 million to $50.0 million);
increase the borrowing base percentage of the net orderly liquidation value as it relates to the multi-client data library (not to exceed $28.5 million, up from the previous maximum of $15.0 million for the multi-client data library component);
include the eligible billed receivables of the Mexican Subsidiary up to a maximum of $5.0 million in the borrowing base calculation and joins the Mexican Subsidiary as a monthlyborrower thereunder (with a maximum exposure of $5.0 million) and require the equity and assets of the Mexican Subsidiary to be pledged to secure obligations under the facility;
modify the interest rate such that the maximum interest rate remains consistent with the fixed interest rate prior to the Third Amendment (that is, 3.00% per annum for domestic rate loans and 4.00% per annum for LIBOR rate loans), but now lowers the range down to a minimum interest rate of 2.00% for domestic rate loans and 3.00% for LIBOR rate loans based on a leverage ratio for the preceding four-quarter period;
decrease the minimum excess borrowing base.availability threshold which (if the Borrowers have minimum excess borrowing availability below any such threshold) triggers the agent’s right to exercise dominion over cash and deposit accounts; and
modify the trigger required to test for compliance with the fixed charges coverage ratio.
The borrowing base under the Credit Facility will increase or decrease monthly using a formula based on certain eligible receivables, eligible inventory and other amounts, including a percentage of the net orderly liquidation value of ourthe Borrowers’ multi-client data library (not to exceed $15.0 million for the multi-client data library component).library. As of September 30, 2017,2018, the borrowing base under the Credit Facility was $22.1$42.8 million, and there was $10.0 million ofzero outstanding indebtedness under the Credit Facility. Even though the Company experienced a significant increase in its accounts and unbilled receivables, those increases were part of the Company’s foreign operations which are not included the borrowing base calculation.
The Credit Facility requires us to maintain compliance with various covenants. At September 30, 2017,2018, we were in compliance with all of the covenants under the Credit Facility. For further information regarding our Credit Facility, see above Footnote 35Long-term Debt” of Footnotes to Unaudited Condensed Financial Statements.

Meeting our Liquidity Requirements
As of September 30, 2017,2018, our total outstanding indebtedness (including capital lease obligations) was approximately $155.3$120.8 million, including approximately $120.6 million outstanding Second Lien Notes $28.5 million outstanding Third Lien Notes, $10.0 million outstanding indebtedness under our Credit Facility, $0.5maturing in December 2021, $3.4 million of equipment capital leases.leases and other short-term debt, partially offset by $3.2 million of debt issuance costs.
For the Current Period, total capital expenditures, including the investments in our multi-client data library, were $17.620.4 million. We expect investments in our multi-client data library this year to be in the range of $20$30 million to $30$35 million. We expect capital expenditures related to property, plant, equipment and seismic rental assets to be in the range of $1 million to $2 million in 2017.2018.
ForDuring the Current Period, we paid $0.6the remaining $1.25 million of the $5.0 million litigation accrual we established in the first quarter of 2017. In addition, we reclassified the $28.5 million outstanding Third Lien Notes to a current liability as this balance matures in the second quarter 2018. With respect to our ongoing WesternGeco litigation and the approaching maturity of our outstanding Third Lien Notes, weWe believe that our existing cash balance, cash from operations and undrawn availability under our Credit Facility will be sufficient to meet our anticipated cash needs for at least the next 12 months. However, as described at Part II, Item 1. “Legal Proceedings,” there are possible scenarios involving an outcome in the WesternGeco lawsuit that could materially and adversely affect our liquidity.liquidity and as a result, our business, financial condition and results of operations.

Inflation and Seasonality
Inflation in recent years has not had a material effect on our cost of goods or labor, or the prices for our products or services. Traditionally, our business has been seasonal, with strongest demand often occurring in the fourth quarter of our fiscal year.
Critical Accounting Policies and Estimates
Refer to our Annual Report on Form 10-K as amended for the year ended December 31, 20162017, for a complete discussion of our significant accounting policies and estimates. On January 1, 2018 we adopted Accounting Standard Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers”, (“new revenue standard”), which did not have a material impact on our consolidated balance sheets or consolidated statement of operations for any of our reporting segments. On January 1, 2019 we will adopt Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842)”, we expect that the adoption of the standard will add between $50 million to $60 million in right-of-use assets and lease obligations on our consolidated balance sheet and will not significantly impact our income statement. We plan to elect the practical expedients upon transition which will retain the lease classification for leases that exist prior to the adoption of the standard.
There have been no other material changes in the Current Period regarding our critical accounting policies and estimates. For discussion of recent accounting pronouncements,our adoption of the new revenue standards, see Footnote 134Recent Accounting Pronouncements”Revenue From Contracts With Customers” of Footnotes to Unaudited Condensed Consolidated Financial Statements.
Leases
In February 2016, the Financials Account Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842)” which introduces the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. The guidance will be effective for annual reporting periods beginning after December 15, 2018 and interim periods within those fiscal years with early adoption permitted. We will adopt ASU 2016-02 on January 1, 2019. We are currently evaluating its operating leases related to offices, processing centers, warehouse spaces and, to a lesser extent, certain equipment, we expect that the adoption of the standard will add between $50 million to $60 million in right-of-use assets and lease obligations on our consolidated balance sheet and will not significantly impact our income statement. We plan to elect the practical expedients upon transition which will retain the lease classification for leases that exist prior to the adoption of the standard.
Foreign Sales Risks
The majority of our foreign sales are denominated in U.S. dollars. Product revenues are allocated to geographical locations on the basis of the ultimate destination of the equipment, if known. If the ultimate destination of such equipment is not known, product revenues are allocated to the geographical location of initial shipment. Service revenues, which primarily relate to our E&P Technology & Services segment, are allocated based upon the billing location of the customer. For the Current and Comparable Periods, international sales comprised 78%76% and 79%78%, respectively, of total net revenues.

PART II — OTHER INFORMATION
Item 1. Legal Proceedings
WesternGeco
In June 2009, WesternGeco L.L.C. (“WesternGeco”) filed a lawsuit against us in the United States District Court for the Southern District of Texas, Houston Division. In the lawsuit, styled WesternGeco L.L.C. v. ION Geophysical Corporation, WesternGeco alleged that we had infringed several method and apparatus claims contained in four of its United States patents regarding marine seismic streamer steering devices.
The trial began in July 2012. A verdict was returned by the jury in August 2012, finding that we infringed the claims contained in the four patents by supplying our DigiFIN® lateral streamer control units and the related software from the United States and awarded WesternGeco the sum of $105.9 million in damages, consisting of $12.5 million in reasonable royaltyroyalties and $93.4 million in lost profits.
In June 2013, the presiding judge entered a Memorandum and Order, rulingdenying the Company’s post-verdict motions that challenged the jury’s infringement findings and the damages amount. In the Memorandum and Order, the judge also ruled that WesternGeco iswas entitled to be awarded supplemental damages for the additional DigiFIN units that were supplied from the United States before and after the trial that were not included in the jury verdict due to the timing of the trial. In October 2013, the judge entered another Memorandum and Order, ruling on the number of DigiFIN units that arewere subject to supplemental damages and also ruling that the supplemental damages applicable to the additional units shouldwere to be calculated by adding together the jury’s previous reasonable royalty and lost profits damages awards per unit, resulting in supplemental damages of $73.1 million.
In April 2014, the judge entered another Order, ruling that lost profits should not have been included in the calculation of supplemental damages in the October 2013 Memorandum and Order and reducedreducing the supplemental damages award in the case from $73.1 million to $9.4 million. In the Order, the judge also further reduced the damages awardawarded in the case by $3.0 million to reflect a settlement and license that WesternGeco entered into with a customer of ours that had purchased and used DigiFIN units that were also included in the damage amounts awarded against us.
In May 2014, the judge signed and entered a Final Judgment against us in the amount of $123.8 million related to the case.million. The Final Judgment also included an injunction that enjoins us, our agents and anyone acting in concert with us, from supplying in or from the United States the DigiFIN product or any parts unique to the DigiFIN product, or any instrumentality no more than colorably different from any of these products or parts, for combination outside of the United States. We have conducted our business in compliance with the district court’sDistrict Court’s orders in the case, and we have reorganized our operations such that we no longer supply the DigiFIN product or any part unique to the DigiFIN product in or from the United States.
We and WesternGeco each appealed the Final Judgment to the United States Court of Appeals for the Federal Circuit in Washington, D.C. (the “Court of Appeals”). On July 2, 2015, the Court of Appeals reversed in part the Final Judgment of the District Court’s judgment,Court, holding the District Court erred by including lost profits in the Final Judgment. Lost profits were $93.4 million and prejudgment interest on the lost profits was approximately $10.9 million of the $123.8 million Final Judgment. Pre-judgment interest on the lost profits portion will be treated in the same way as the lost profits. Post-judgment interest will likewise be treated in the same fashion. On July 29, 2015, WesternGeco filed a petition for rehearing en banc before the Court of Appeals. On October 30, 2015, the Court of Appeals denied WesternGeco’s petition for rehearing en banc.
As previously disclosed, we recorded a loss contingency accrual of $123.8 million. As a result of the reversal by the Court of Appeals, as of June 30, 2015, we reduced our loss contingency accrual to $22.0 million.
On February 26, 2016, WesternGeco filed a petition for writ of certiorari by the Supreme Court. We filed our response on April 27, 2016. Subsequently, on June 20, 2016, the Supreme Court refused to disturbvacated the Court of AppealsAppeals’ ruling finding noalthough it did not address the lost profits as a matter of law.  Separately,question at that time. Rather, in light of the changes in case law regarding the standard of proof for willfulness in the Halo and Stryker cases, the Supreme Court indicated that the case should be remanded to the Federal CircuitCourt of Appeals for a determination of whether or not the willfulness determination by the District Court was appropriate.
On October 14, 2016, the Court of Appeals issued a mandate returning the case to the District Court for consideration of whether or not additional damages for willfulness were appropriate.
On November 14, 2016, the District Court issued an order reducing the amount of the appeal bond from $120.0 million to $65.0 million, ordered the sureties to pay principal and interest on the royalty damages previously awarded and declined to issue a final judgment until after consideration of whether enhanced damages related tofor willfulness shouldwould be awarded in the case.awarded. While we did not agreedisagreed with the unusual decision by the District Court ordering payment of the royalty damages and interest without a final judgment, on November 25, 2016, we paid WesternGeco the $20.8 million due pursuant to the order, at which point we reduced our loss contingency accrual to WesternGeco on November 25, 2016.zero.
    

On March 14, 2017, the District Court held a hearing on whether or not additional damages for willfulness would be payable. The Judge found that ION’s infringement was willful, based on his perception that ION did not adequately investigate the scope of the patent,patents, and ION’s conduct during trial. However, in his ruling at the hearing, he limited enhanced damages to $5.0 million because it was a “close case,” there was no evidence of copying, and ION was simply acting as a competitor in a capitalist marketplace. The District Court also ordered the appeal bond to be released and discharged. The Court’s findings and ruling were memorialized in an order issued on May 16, 2017. On June 30, 2017, WesternGeco and we jointly agreed that neither party would appeal the District Court's award of $5.0 million in enhanced damages. The parties also agreed that the $5.0 million would be paid over the course of twelve months with $1.25 million being paid in two installments of $0.625 million in 2017 and the remaining $3.75 million being paid in three quarterly payments of $1.25 million beginning January 1, 2018.12 months. This agreement was memorialized by the court in an order issued on July 26, 2017. Upon assessment of the $5.0 million in enhanced damages, we accrued $5.0 million in the first quarter of 2017. As we have made the payments, the accrual has been adjusted, and as of June 30, 2018, the loss contingency accrual was zero.
WesternGeco filed a second petition for writ of certiorari in the U.S. Supreme Court on February 17, 2017, appealing the lost profits issue again. We filed our response to WesternGeco’s second attempt to appeal to the Supreme Court the lost profits issue, raising both the substantive matters we addressed by opposing WesternGeco’s first petition, and also raisingadvancing a procedural argument that WesternGeco cannotcould not raise the same issue for a second time in a second petition for certiorari. On May 30, 2017, the Supreme Court called for the views of the U.S. Solicitor General regarding whether or not to grant certiorari. (The U.S. Supreme Court has discretion to hear, or not hear, WesternGeco’s appeal; granting WesternGeco’s request for a writ of certiorari would mean that the U.S. Supreme Court decided to hear WesternGeco’s appeal of the decision by the United States Court of Appeals for the Federal Circuit with respect to the lost profits issue.  If the Supreme Court agrees to hear WesternGeco’s appeal, we will contest WesternGeco’s appeal at the Supreme Court.  In such a case, it is possible that the Supreme Court could issue a ruling adverse to ION.) We and WesternGeco each met with the Solicitor General’s office in late July, 2017. TheOn December 6, 2017, the Solicitor General is expectedfiled its brief, and took the position that the Supreme Court ought to issue its briefgrant certiorari. On January 12, 2018, the Supreme Court granted certiorari as to whether the Court of Appeals erred in holding that lost profits arising from use of prohibited combinations occurring outside of the United States are categorically unavailable in cases where patent infringement is proven under 35 U.S.C. § 271(f)(2) (the specific statute under which we were ultimately held to have infringed WesternGeco’s patents and upon which the District Court and the Court of Appeals relied in entering their final rulings).
The Supreme Court should grant certiorari nearheard oral arguments on April 16, 2018. At oral arguments, we argued that the endCourt of 2017 or the beginning of 2018, although there is no deadline forAppeals’ decision that eliminated lost profits ought to be affirmed. WesternGeco and the Solicitor General argued that the Court of Appeals’ decision that eliminated lost profits ought to be reversed.
On June 22, 2018, the Supreme Court reversed the judgment of the Court of Appeals, held that the award of lost profits to WesternGeco by the District Court was a permissible application of Section 284 of the Patent Act, and remanded the case back to the Circuit Court for further proceedings consistent with its (the Supreme Court’s) opinion. On July 24, 2018, the Supreme Court issued the judgment that returned the case to the Court of Appeals.
At the Court of Appeals, in the case leading up to the Supreme Court, we presented multiple arguments as to why the District Court’s award of lost profits was improper. The lost profits damages awarded by the District Court were based on the use of our products by our customers outside of the United States. We argued at the Court of Appeals, and at the Supreme Court, that, as a matter of law, WesternGeco cannot recoup lost profits for the overseas use of our products. This issue, decided in favor of WesternGeco in the recent Supreme Court opinion, was the only issue reached by the Supreme Court in that decision.
We also argued in the Court of Appeals that, under the jury instructions given in our case, the jury was required to find that we had been a direct competitor of WesternGeco in the survey markets where WesternGeco lost profits in order for WesternGeco to recoup them. Because the Court of Appeals ruled in favor of us on the first argument, and overturned the award of lost profits on that basis, the Court of Appeals did not rule on our “direct competitor” argument, and that argument was not presented to the Supreme Court for review. Thus, while the Supreme Court overturned the Court of Appeals’ decision that WesternGeco should not be allowed to recover foreign lost profits under the Patent Act, the Supreme Court did not order us to pay any amount with respect to lost profits, but rather remanded the case back to the Court of Appeals for further consideration of whether lost profits are payable by us in this case.
On July 25, 2018, we filed a motion for leave to file supplemental briefing in the Court of Appeals, and concurrently, filed a brief arguing that the judgment of the District Court as to both lost profits and reasonable royalties should be vacated, and that the case should be remanded to the District Court for a new determination on damages. On July 27, 2018, the Court of Appeals vacated its September 21, 2016 judgment with respect to damages, and ordered WesternGeco and ION to submit supplemental briefing on what relief is appropriate in light of the Supreme Court’s decision. This order rendered our motion for leave to submit briefing moot, and, accordingly, the Court of Appeals denied our motion as moot. ION and WesternGeco each submitted briefing in accordance with the Court of Appeals’ order (with the last brief being filed with the Court of Appeals on September 7, 2018).

Other proceedings may have an impact on WesternGeco’s ability to recover lost profits damages and reasonable royalties even if we do not prevail on the “direct competitor” argument in the Court of Appeals, and were addressed, along with the direct competitor argument, in the parties’ briefing to the Court of Appeals (further described below). In particular, we were a party to a challenge to the validity of several of WesternGeco’s patent claims by means of an Inter Partes Review (“IPR”) with the Patent Trial and Appeal Board (“PTAB”). While the above-described lawsuit was pending on appeal, the PTAB invalidated four of the six patent claims that formed the basis for the jury verdict in the lawsuit. WesternGeco appealed that decision to the Court of Appeals, which heard the ION and WesternGeco’s arguments on January 23, 2018. The Court of Appeals affirmed the PTAB’s invalidation of the patents on May 7, 2018, and on July 16, 2018, the Court of Appeals denied WesternGeco’s petition for a panel rehearing and a rehearing en banc. This decision by the Court of Appeals may provide a separate ground for reducing or vacating any lost-profits or reasonable royalty award in the lawsuit.
WesternGeco argued, in its pending briefs before the Court of Appeals, that the only issue that remains to be decided is whether lost profits are unavailable to WesternGeco due to our “direct competitor” argument, and argued that the invalidation of four of its six patent claims by the Court of Appeals (which invalidation WesternGeco intends to appeal to the Supreme Court) should have no effect on lost profits or on the royalty award we already paid. WesternGeco also argued that lost profits should be available notwithstanding our “direct competitor” argument.
We argued that lost profits are not available on the basis of the “direct competitor” argument, that the Court of Appeals’ affirmation that four of the six patent claims at issue are invalid has a preclusive effect on WesternGeco’s damages claims, and that the Court of Appeals should order a new trial as to the royalty damages we already paid. We argued, in the alternative, that if the Court of Appeals does not find our “direct competitor” argument persuasive, the Court of Appeals should nonetheless vacate the District Court’s award of royalty damages and lost profits damages and order a new trial as to both royalty damages and lost profits.
On October 19, 2018, the Court of Appeals scheduled oral arguments for the issues we raised and WesternGeco in their briefs pending before that court. Oral arguments are scheduled to take place on November 16, 2018.
We may not ultimately prevail in any of the appeals processes noted above and we could be required to pay some or all of the lost profits that were awarded by the District Court if the judgment of the District Court is upheld by the Court of Appeals on remand, or if a new trial is granted and a new judgment issues. Our assessment that we do not have a loss contingency (other than the $1.25 million noted above) may change in the future due to other developments at the Supreme Court, Court of Appeals, or District Court, and other events, such as changes in applicable law, and such reassessment could lead to the determination that an opinion.additional loss contingency is probable, which could have a material effect on our business, financial condition and results of operations. Our assessments disclosed in this Quarterly Report on Form 10-Q or elsewhere are based on currently available information and involve elements of judgment and significant uncertainties. See above, Footnote 68Litigation” of Footnotes to Unaudited Condensed Financial StatementsStatements”.
Other Litigation
We have been named in various other lawsuits or threatened actions that are incidental to our ordinary business. Litigation is inherently unpredictable. Any claims against us, whether meritorious or not, could be time-consuming, cause us to incur costs and expenses, require significant amounts of management time and result in the diversion of significant operational resources. The results of these lawsuits and actions cannot be predicted with certainty. We currently believe that the ultimate resolution of these matters will not have a material adverse effect on our financial condition or results of operations or our liquidity.

We rely on highly skilled personnel in our businesses, and if we are unable to retain or motivate key personnel or hire qualified personnel, we may not be able to grow effectively.
Our performance is largely dependent on the talents and efforts of highly skilled individuals. Our future success depends on our continuing ability to identify, hire, develop, motivate and retain skilled personnel for all areas of our organization. We require highly skilled personnel to operate and provide technical services and support for our businesses. Competition for qualified personnel required for our data processing operations and our other segments’ businesses has intensified recently. Our growth has presented challenges to us to recruit, train and retain our employees while managing the impact of potential wage inflation and the lack of available qualified labor in some markets where we operate. A well-trained, motivated and adequately-staffed work force has a positive impact on our ability to attract and retain business. Our continued ability to compete effectively depends on our ability to attract new employees and to retain and motivate our existing employees.
These forward-looking statements reflect our best judgment about future events and trends based on the information currently available to us. Our results of operations can be affected by inaccurate assumptions we make or by risks and uncertainties known or unknown to us. Therefore, we cannot guarantee the accuracy of the forward-looking statements. Actual events and results of operations may vary materially from our current expectations and assumptions.

Information regarding factors that may cause actual results to vary from our expectations, referred to as “risk factors,” appears in our Annual Report on Form 10-K as amended for the year ended December 31, 2016,2017, in Part I, Item 1A. “Risk Factors,” as previously filed with the SEC, as well as the following additional risk factors.
If we cannot meet the continued listing requirements of the New York Stock Exchange (the “NYSE”), the NYSE may delist our common shares, which would have an adverse impact on the trading volume, liquidity and market price of our common shares.
On July 20, 2017, ION Geophysical Corporation (the “Company”) received written notice from the New York Stock Exchange (the “NYSE”) that it is not in compliance with the continued listing standards set forth in Section 802.01B of the NYSE Listed Company Manual. The Company is considered below criteria established by the NYSE for continued listing because its average market capitalization was less than $50 million over a consecutive 30 trading-day period, and at the same time its last reported stockholders’ equity was below $50 million.
On August 28, 2017, the Company submitted a plan to the NYSE to demonstrate the Company’s ability to bring the Company into conformity with the continued listing standards within 18 months of the date of the NYSE’s initial notice. On October 5, 2017, the NYSE notified the Company that the NYSE had accepted the Company’s plan. Accordingly, the Company is subject to ongoing monitoring for compliance with the plan.
During the 18-month period, the Company's shares will continue to be listed and traded on the NYSE, subject to its continued compliance with the plan and other NYSE continued listing standards. The Company can provide no assurances that it will be able to satisfy any of the steps outlined above and maintain a listing of its shares.
There is no immediate impact on the listing of the Company’s common stock, which will continue to trade on the NYSE, subject to the Company’s compliance with other listing standards. The Company will continue to file periodic and other reports with the SEC under applicable federal securities laws.

A delisting of our common shares from the NYSE would negatively impact us because it would: (i) reduce the liquidity and market price of our common shares; (ii) reduce the number of investors willing to hold or acquire our common shares, which could negatively impact our ability to raise equity financing; (iii) limit our ability to use a registration statement to offer and sell freely tradable securities, thereby preventing us from accessing the public capital markets, and (iv) impair our ability to provide equity incentives to our employees.
We face a significant debt maturity in 2018.
Our $28.5 million aggregate principal amount of Senior Secured Third-Priority Lien notes mature on May 15, 2018.  If our cash flows from operations and other capital resources are insufficient to pay off such notes, we may face substantial liquidity problems and may be forced to reduce or delay investments, dispose of material assets or operations, or issue additional debt or equity. We may not be able to take such actions, if necessary, on commercially reasonable terms or at all. Our inability to generate sufficient cash flows to satisfy our debt obligations, or to refinance our indebtedness on commercially reasonable terms or at all, would materially and adversely affect our financial position and results or operations.SEC.

Stock Repurchase Program
On November 4, 2015, our board(c) During the three months ended September 30, 2018, in connection with the vesting of directors approved a stock repurchase program authorizing us to repurchase, from time to time from November 10, 2015 through November 10, 2017, up to $25 million in(or lapse of restrictions on) shares of our outstanding common stock.
