ION GEOPHYSICAL CORPORATION AND SUBSIDIARIES
FOOTNOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
(1)    Summary of Significant Accounting Policies
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, 2018, has been derived from the Company’s audited consolidated financial statements at that date. The condensed consolidated balance sheet at JuneSeptember 30, 2019, and the condensed consolidated statements of operations, comprehensive income (loss)loss and condensed consolidated statements of stockholders' (deficit) equity for the three and sixnine months ended JuneSeptember 30, 2019 and 2018 and the condensed consolidated statements of cash flows for the sixnine months ended JuneSeptember 30, 2019 and 2018, are unaudited. In the opinion of management, all adjustments of a normal recurring nature that are necessary for a fair presentation of the results of the interim period have been included. Interim results are not necessarily indicative of the operating results for a full year or of future operations. Intercompany transactions and balances have been eliminated.
The Company’s condensed consolidated financial statements reflect a non-redeemable noncontrolling interest in a majority-owned affiliate which is reported as a separate component of equity in “Noncontrolling interest” in the condensed consolidated balance sheets. Net income attributable to noncontrolling interest is stated separately in the condensed consolidated statements of operations. 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 (“GAAP”) 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 GAAP have been omitted. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.
Certain prior period amounts have been reclassified to conform to the current period presentation, including the change in reportable segments presentation which had no impact on the condensed consolidated financial statements and the recognition of right-of-use (“ROU”) assets and operating lease liabilities on the condensed consolidated balance sheets as a result of the adoption of the new lease standard. See Note 2 “Recent Accounting Pronouncements.
Significant Accounting Policies
The Company’s significant accounting policies are disclosed in Note 1 “Summary of Significant Accounting Policies.” of the Annual Report on Form 10-K for the year ended December 31, 2018. There have been no changes in such policies or the application of such policies during the sixnine months ended JuneSeptember 30, 2019 except as discussed in Note 2 “Recent Accounting PronouncementsPronouncements.” and Note 11 “Lease Obligations.
Use of Estimates
The preparation of condensed consolidated financial statements in conformity with GAAP requires the use of estimates and assumptions by management that affects the reported amounts in the condensed consolidated financial statements and accompanying notes. Areas involving significant estimates include, but not limited to, accounts and unbilled receivables, inventory valuation, sales forecast related to multi-client data libraries, impairment of property, plant and equipment and goodwill and deferred taxes. Actual results could materially differ from those estimates.
(2)    Recent Accounting Pronouncements
Accounting Pronouncements Recently Adopted
On January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) 2016-2, “Leases (Topic 842)” using the modified retrospective method. This ASU requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under the previous guidance. The Company used January 1, 2018, the beginning of the earliest comparative period presented in its condensed consolidated financial statements, as the date of initial application. The Company elected the practical expedients upon transition which will retain the lease classification for leases and any unamortized initial direct costs that existed prior to the adoption of the standard.
The adoption of the standard resulted in ROU assets of $59.5 million and operating lease liabilities of $70.6 million on the condensed consolidated balance sheets as of January 1, 2018. The difference between the ROU assets and operating lease liabilities is due to the derecognition of $11.1 million in deferred rent recorded within other long-term liabilities. There was no
    

impact on the condensed consolidated statements of operations and cash flows. The adoption of the standard had no impact on the debt covenant compliance under existing agreements. Short-termThe Company elected the practical expedient related to short-term leases, which are leases with a duration of twelve months or less, as such, they have not been recorded in the condensed consolidated balance sheets. See Note 11 “Lease Obligations.” for further discussion.
Accounting Pronouncements Not Yet Adopted
In June 2016, the Financial Accounting Standards Board issued ASU No. 2016-13, “Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments.” The guidance will replace the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance is effective for public companies for interim and annual periods beginning after December 15, 2019, with early adoption permitted for interim and annual periods beginning after December 15, 2018. The Company is in the initial stages of evaluating the impact of this standard on the condensed consolidated financial statements. The Company does not currently expect the adoption of this standard to have a material impact on the condensed consolidated financial statements.
(3)    Segment Information
During the first quarter of 2019, the Company consolidated its operating segments from three into two, eliminating the separate presentation of its Ocean Bottom Integrated Technologies segment. This consolidation aligns with the Company’s asset light business model and evolved strategy to commercialize components of the Company’s next generation ocean bottom nodal system, 4Sea™, instead of operating a crew. The Company is offering 4Sea components more broadly to the growing number of Ocean Bottom Seismic (“OBS”) service providers under recurring revenue commercial strategies to enable it to share in the value the technology delivers.strategies. The Company may also license the right to manufacture and use the 4Sea nodal technology to a service provider on a value-based pricing model, such as a royalty stream. Revenues from 4Sea would beare being recognized through the relevant segments, either E&P Technology & Services or Operations Optimization.
Accordingly, as of first quarter 2019, the Company evaluates and reviews its results of operations based on two reporting segments: E&P Technology & Services and Operations Optimization. Refer to Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for information about each business segment’s business, products and services.
The segments represent components of the Company for which separate financial information is available that is utilized on a regular basis by the Chief Operating Decision Maker in determining how to allocate resources and evaluate performance. The Company measures segment operating results based on income (loss) from operations.
Previously reported segment information has been retrospectively revised throughout the condensed consolidated financial statements, as applicable, for all periods presented to reflect the changes in the Company’s reporting segments. These changes did not have an impact on the Company’s condensed consolidated financial statements. These changes did not affect the Company’s reporting units used for allocating and testing goodwill for impairment.

(4)     Revenue From Contracts With Customers
The Company derives revenue from the (i) sale or license of multi-client and proprietary data, imaging services and E&P Advisors consulting services within its E&P Technologies & Services segment; (ii) sale, license and repair of seismic data acquisition systems and other equipment; and (iii) sale or license of seismic command and control software systems and software solutions for operations management within its Operations Optimization segment. All E&P Technology & Services’ revenues and the services component of Optimization Software & Services’ revenues under Operations Optimization segment are classified as service revenues. All other revenues are classified as product revenues.
    

The Company uses a five-step model to determine proper revenue recognition from customer contracts in accordance with Accounting Standards Codification Topic 606 (“ASC 606”). 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 applies the practical expedient in ASC 606 and does not disclose information about remaining contractual future performance obligations with an original term of one year or less within the footnotes. The Company does not have any contractual future performance obligations with an original term of over one year.

Mexican Subsidiary are collectively, the “Subsidiary Borrowers”, together with ION Geophysical Corporation are the “Borrowers”) — the financial institutions party thereto, as lenders, and 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 “Third Amendment”), amending 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, dated as of August 4, 2015 and the Second Amendment to Revolving Credit and Security Agreement, dated as of April 28, 2016, the “Credit Agreement”). The Credit Agreement, as amended by the First Amendment, the Second Amendment and the Third Amendment is herein called the “Credit Facility”).
The Credit Facility is available to provide for the Borrowers’ general corporate needs, including working capital requirements, capital expenditures, surety deposits and acquisition financing.
The Third Amendment amended the Credit Agreement to, among other things:
extend the maturity date of the Credit Facility by approximately four years (from August 22, 2019 to August 16, 2023), subject to the Company’s retirement or extension of the maturity date of its Second Lien Notes, as defined below, which mature 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 borrower 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 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, which is further described below.
The maximum amount under the Credit Facility is the lesser of $50.0 million or a monthly borrowing base. 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 the Borrowers’ multi-client library.  As of JuneSeptember 30, 2019, the undrawn borrowing base availability under the Credit Facility was $38.0$37.6 million, and there was no outstanding indebtedness under the Credit Facility.
The obligations of Borrowers under the Credit Facility are secured by a first-priority security interest in 100% of the stock of the Subsidiary Borrowers and 65% of the equity interest in ION International Holdings L.P., and by substantially all other assets of the Borrowers. However, the first-priority security interest in the other assets of the Mexican Subsidiary is capped to a maximum exposure of $5.0 million.
The Credit Facility contains covenants that, among other things, limit or prohibit the Borrowers, subject to certain exceptions and qualifications, from incurring additional indebtedness in excess of permitted indebtedness (including finance lease obligations), repurchasing equity, paying dividends or distributions, granting or incurring additional liens on the Borrowers’ properties, pledging shares of the Borrowers’ subsidiaries, entering into certain merger transactions, entering into transactions with the Company’s affiliates, making certain sales or other dispositions of the Borrowers’ assets, making certain investments, acquiring other businesses and entering into sale-leaseback transactions with respect to the Borrowers’ property.
The Credit Facility requires that the Borrowers maintain a minimum fixed charge coverage ratio of 1.1 to 1.0 as of the end of each fiscal quarter during the existence of a covenant testing trigger event. The fixed charge coverage ratio is defined as the ratio of (i) ION Geophysical Corporation’s EBITDA,earnings before interest, taxes, depreciation and amortization (“EBITDA”), minus unfunded capital expenditures made during the relevant period, minus distributions (including tax distributions) and dividends made during the relevant period, minus cash taxes paid during the relevant period, to (ii) certain debt payments made during the relevant period. A covenant testing trigger event occurs upon (a) the occurrence and continuance of an event of default under the Credit Facility or (b) by a two-step process based on (i) a minimum excess borrowing availability threshold (excess borrowing availability less than $6.25 million for five consecutive days or $5.0 million on any given day), and (ii) the Borrowers’ unencumbered cash maintained in a PNC deposit account is less than the Borrowers’ then outstanding obligations.
At JuneSeptember 30, 2019, the Company was in compliance with all of the covenants under the Credit Facility.
The Credit Facility contains customary event of default provisions (including a “change of control” event affecting ION Geophysical Corporation), the occurrence of which could lead to an acceleration of ION Geophysical Corporation’s obligations under the Credit Facility.
    

Senior Secured Notes
ION Geophysical Corporation’s 9.125% Senior Secured Second Priority Notes due December 2021 (the “Second Lien Notes”) are senior secured second-priority obligations guaranteed by the Material U.S. Subsidiaries and the Mexican Subsidiary (each as defined above and herein below, with the reference to the Second Lien Notes, the “Guarantors”). Interest on the Second Lien Notes is payable semiannually in arrears on June 15 and December 15 of each year during their term, except that the interest payment otherwise payable on June 15, 2021 will be payable on December 15, 2021.
The April 2016 indenture governing the Second Lien Notes contains certain covenants that, among other things, limits or prohibits ION Geophysical Corporation’s ability and the ability of its restricted subsidiaries to take certain actions or permit certain conditions to exist during the term of the Second Lien Notes, including among other things, incurring additional indebtedness in excess of permitted indebtedness, creating liens, paying dividends and making other distributions in respect of ION Geophysical Corporation’s capital stock, redeeming ION Geophysical Corporation’s capital stock, making investments or certain other restricted payments, selling certain kinds of assets, entering into transactions with affiliates, and effecting mergers or consolidations. These and other restrictive covenants contained in the Second Lien Notes Indenture are subject to certain exceptions and qualifications. All of ION Geophysical Corporation’s subsidiaries are currently restricted subsidiaries.
At JuneSeptember 30, 2019, the Company was in compliance with all of the covenants under the Second Lien Notes.
On or after December 15, 2019, the Company may, on one or more occasions, redeem all or a part of the Second Lien Notes at the redemption prices set forth below, plus accrued and unpaid interest and special interest, if any, on the Second Lien Notes redeemed during the twelve-month period beginning on December 15th of the years indicated below:
Date Percentage
2019 105.50%
2020 103.50%
2021 and thereafter 100.00%
(6)    Net Loss Per Share
Basic net loss per share is computed by dividing net loss applicable to common shares by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is determined based on the assumption that dilutive restricted stock and restricted stock unit awards have vested and outstanding dilutive stock options have been exercised and the aggregate proceeds were used to reacquire common stock using the average price of such common stock for the period. The total number of shares issuable pursuant to outstanding stock options at JuneSeptember 30, 2019 and 2018 of 766,659700,759 and 815,791,804,936, respectively, were excluded as their inclusion would have an anti-dilutive effect. The total number of shares issuable pursuant to restricted stock units awards outstanding at JuneSeptember 30, 2019 and 2018 of 794,994926,917 and 128,131, respectively, were excluded as their inclusion would have an anti-dilutive effect.
(7)    Income Taxes
The Company maintains a valuation allowance for substantially all of its deferred tax assets. A valuation allowance is established or maintained when it is “more likely than not” that all or a portion of deferred tax assets will not be realized. The Company will continue to record a valuation allowance for the substantial majority of its deferred tax assets until there is sufficient evidence to warrant reversal.
The tax provision for the sixnine months ended JuneSeptember 30, 2019 has been calculated using the Company’s overall estimated annual effective tax rate based on projected 2019 full year results. The Company’s effective tax rates for the three months ended JuneSeptember 30, 2019 and 2018 were (48.8)%822.1% and (0.6)(38.6)%, respectively. The Company’s effective tax rates for the sixnine months ended JuneSeptember 30, 2019 and 2018 were (16.2)(31.7)% and (2.9)(6.9)%, respectively. The Company’s effective tax rates for the three and sixnine months ended JuneSeptember 30, 2019 and 2018 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 sixnine months ended JuneSeptember 30, 2019 of $4.1$7.9 million primarily relates to results from the Company’s non-U.S. businesses.
As of JuneSeptember 30, 2019, the Company has approximately $0.4 million of unrecognized tax benefits and does not expect to recognize significant increases in unrecognized tax benefits during the next twelve-month period. Interest and penalties, if any, related to unrecognized tax benefits are recorded in income tax expense.

As of JuneSeptember 30, 2019, the Company’s U.S. federal tax returns for 20152016 and subsequent years remain subject to examination by tax authorities. In the Company’s foreign tax jurisdictions, tax returns for 2012 and subsequent years generally remain open to examination.


(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 (the “District Court”). In the lawsuit, styled WesternGeco L.L.C. v. ION Geophysical Corporation, WesternGeco alleged that the Company had infringed four of their patents concerning marine seismic surveys.
Trial began in July 2012, and the jury returned a verdict in August 2012. The jury found that the Company infringed the six “claims” contained in four of WesternGeco’s patents by supplying itsthe Company’s DigiFIN® lateral streamer control units from the United States, and awarded WesternGeco more than $100 million in damages.States. (In patent law, a “claim” is a technical legal term; an infringer infringes on one or more “claims” of a given patent.)
In May 2014, the District Court entered a Final Judgment against the Company in the amount of $123.8 million. This included the jury award ($12.5 million in reasonable royalties plus $93.4 million in lost profits), $10.9 million in pre-judgment interest on lost profits, and $9.4 million in supplemental damages that the judge imposed for DigiFIN units that were supplied from the U.S. during the trial and during other periods that the jury did not consider. The Final Judgment also enjoined the Company from supplying DigiFINs or any parts unique to DigiFINs in or from the United States. The Company has conducted its business in compliance with the District Court’s orders, and has reorganized its operations such that it no longer supplies DigiFINs or any parts unique to DigiFINs in or from the United States.
On July 2, 2015,As of 2018, the Company has paid WesternGeco the $25.8 million of the Final Judgment (the portion of the judgment representing reasonable royalty damages and enhanced damages, plus interest).
However, as further described below, the balance of the judgment against the Company ($98.0 million, representing lost profits from surveys performed by the Company’s customers outside of the United State, plus interest) has been vacated, and a new trial ordered, to determine what lost profit damages, if any, WesternGeco is entitled to.
The Final Judgment was vacated after it was appealed to the United States Court of Appeals for the Federal Circuit in Washington, D.C. (the “Court of Appeals”) reversed, in part, the District Court, holding that the lost profits, which were attributable to foreign seismic surveys, were not available to WesternGeco under the Patent Act. The Company had recorded a loss contingency accrual of $123.8 million because of the District Court’s ruling. As a result of the reversal by the Court of Appeals, the Company reduced the loss contingency accrual to $22.0 million.
On November 14, 2016, the District Court ordered our sureties to pay principal and interest on the royalty damages previously awarded. On November 25, 2016, the Company paid WesternGeco the $20.8 million due pursuant, then to the order, and it reduced its loss contingency accrual to zero.
On March 14, 2017, the District Court held a hearing on whether impose additional damages for willfulness. The Judge found that the Company’s infringement was willful, and awarded enhanced damages of $5.0 million to WesternGeco (WesternGeco had sought $43.6 million in such damages.) The District Court also ordered the appeal bond to be released and discharged. On June 30, 2017, the Company and WesternGeco agreed that neither would appeal the District Court's award of $5.0 million in enhanced damages. Upon assessment of the enhanced damages, the Company accrued $5.0 million in the first quarter of 2017 which was paid in full in 2018.
WesternGeco filed a petition in the Supreme Court on February 17, 2017, appealing the Court of Appeal’s decision that had eliminated lost profits. On January 12, 2018, the Supreme Court agreed to hear the appeal. The specific issue before the Supreme Court was whether 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 statute under which the Company was held to have infringed WesternGeco’s patents, and upon which the District Court and Court of Appeals relied in entering their rulings).
The Supreme Court heard oral arguments on April 16, 2018. The Company argued that the Court of Appeals’ decision that eliminated lost profits ought to be affirmed. WesternGeco and the U.S. 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, backagain, to the Court of Appeals for further proceedings consistent with its (the Supreme Court’s) opinion.
On July 27, 2018, the Court of Appeals vacated its earlier decision with respect to lost profits damages, and ordered WesternGeco and the Company to submit supplemental briefing on what relief would be appropriate in light of the Supreme Court’s decision.
   ��

The Company argued to the Court of Appeals that lost profits were not available to WesternGeco because the jury instructions required the jury to find that the Company had been WesternGeco’s direct competitor in the survey markets where WesternGeco had lost profits, and that the jury could not have found so. Additionally, the Company argued that the award of lost profits and reasonable royalties ought to be vacated and retried on separate grounds due to the outcome of an Inter Partes Review (“IPR”) filed with the Patent Trial and Appeal Board (“PTAB”) of the Patent and Trademark Office, in which the PTAB invalidated four of the six patent claims that formed the basis for the lawsuit judgment against the Company. (The Court of Appeals affirmed the PTAB’s findings, and on February 19, 2019, the Supreme Court declined to hear WesternGeco’s appeal on that issue.)Appeals.
On January 11, 2019, the Court of Appeals issued its ruling. In its ruling, the Court of Appeals refused to disturb the award of reasonable royalties to WesternGeco (which the Company paid in 2016), and rejectedbut did not reinstate the Company’s “direct competitor” argument, but vacated the District Court’s award of lost profits damages andaward; rather, the Court of Appeals remanded the case back to the District Court to determine whether to hold a new trial as to lost profits. The
On August 30, 2019, the District Court of Appeals also ruled that its affirmancerefused WesternGeco’s request to reinstate the lost profits awards against the Company, and instead ordered a new trial to determine what lost profits, if any, WesternGeco is entitled to from surveys performed by the Company’s customers outside of the PTAB’s decision eliminatedUnited States.
The District Court’s basis for granting the new trial as to lost profits was that, subsequent to the jury verdict that awarded lost profits, the Patent Trial and Appeal Board (“PTAB”) of the Patent and Trademark Office, in an administrative proceeding, invalidated four of the five patent claims that could have supportedformed the award ofbasis for the lost profits leaving only one remainingjudgment against the Company (that is, the PTAB held that those four patent claim that could support an award of lost profits.
Theclaims should never have been granted), and the Court of Appeals further heldand the Supreme Court both subsequently refused to overturn that the lost profits award can be reinstated by the District Court if the existingfinding. A trial record establishes thatdate for the jury must have found that the technology covered by the one remaining patent claim was essential for performing the surveys upon which lost profits were based. To make such a finding, the District Court must conclude that the present trial record establishes that there was no dispute that the technology covered by the one remaining patent claim, independent of the technology of the now-invalid claims, was required to perform the surveys. The Court of Appeals ruling further provides that if, but only if, the District Court concludes that WesternGeco established at trial, with undisputed evidence, that the remaining claim covers technology that was necessary to perform the surveys, then the District Court may deny a new trial and reinstate lost profits.
On February 19, 2019, the Company filed a motion for a new trial as to lost profits in the District Court. In the motion, the Company argued that a new trial on lost profits is necessary, since WesternGeco cannot demonstrate that it established, at trial, with undisputed evidence, that the one remaining patent claim covers technology that was necessary to perform the surveys upon which the lost profits award was based. On March 20, 2019, WesternGeco filed an opposition to our motion for a new trial, arguing that undisputed evidence established that the one remaining patent claim was necessary to perform the ten lost profits surveys. On that same date, WesternGeco filed a cross motion for entry of a judgment of $105.4 million in lost profits and pre- and post-judgment interest. The Company filed a reply to WesternGeco’s opposition motion on April 9, 2019 and an opposition to WesternGeco’s cross motion on April 18, 2019. On May 3, 2019, WesternGeco filed a reply in support of its cross motion for entry of judgment.has not yet been set.
The Company may not ultimately prevail in the litigation and it could be required to pay some or all of the lost profits that were awarded by the District Court, plus interest, if the District Court denies a new trial on lost profits, or if a new trial is granted and when a new judgment issues.issues in the new trial. 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 a significant 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. The results of these lawsuits and actions cannot be predicted with certainty. The Company currently believes that the ultimate resolution of these matters will not have a material adverse effect on its financial condition or results of operations.

(10)    Stockholder's Equity and Stock-Based Compensation Expense
Public Equity Offering
On February 21, 2018, the Company completed a public equity offering (“Offering”) of its 1,820,000 shares of common stock at a public offering price of $27.50 per share, and warrants to purchase an additional 1,820,000 shares of the Company’s common stock pursuant to the Registration Statement on Form S-3 (No. 33-213769) filed with the Securities and Exchange Commission under the Securities Act of 1933 and declared effective on December 2, 2016.  The net proceeds from this offering were $47.0 million, including transaction expenses. A portion of the net proceeds were used to retire the Company’s $28.5 million Third Lien Notes in March 2018. The warrants have an exercise price of $33.60 per share, are immediately exercisable and were to expire on March 21, 2019. On February 4, 2019, the Company extended expiration of the warrants to March 21, 2020.
    

Stock-Based Compensation
The total number of shares issued or reserved for future issuance under outstanding stock options at JuneSeptember 30, 2019 and 2018 was 766,659700,759 and 815,791,804,936, respectively, and the total number of shares of restricted stock and shares reserved for restricted stock units outstanding at JuneSeptember 30, 2019 and 2018 was 794,994926,917 and 128,131, respectively.

On September 1, 2019, the Company granted 130,000 shares of restricted stock to the new Chief Executive Officer. The vesting of the 65,000 shares is achieved through a time based condition and the vesting of the remaining 65,000 shares is achieved through both a time based condition and performance based condition.
Stock-based compensation expense recognized for the sixnine months ended JuneSeptember 30, 2019 and 2018, totaled $2.8$3.7 million and $2.0$2.5 million, respectively. SARs expense recognized for the sixnine months ended JuneSeptember 30, 2019 and 2018, totaled $2.0$2.7 million and $2.5$2.8 million, respectively.
SARs awards are considered liability awards and as they are ultimately settled in cash. As such, these amounts are incrementally accrued in the liability section of the condensed consolidated balance sheets.sheets over the service period. All of the Company’s currently outstanding SARs awards achieve vesting through both a market condition and a service condition. SARs awards that are fully vested under both conditions are measured at intrinsic value (i.e. the difference between the market price on the last day of the quarter and the strike price of the awards times the number of awards vested and outstanding) and marked to market each quarter until settled. SARs awards that are not fully vested are incrementally accrued over the service period and adjusted to their fair value each quarter until settled based on a valuation model. The Company calculated the fair value of each award as of JuneSeptember 30, 2019 and December 31, 2018 using a Monte Carlo simulation model. The following assumptions were used:

(11)    Lease Obligations
The Company determines if an arrangement is a lease at inception by considering whether (1) explicitly or implicitly identified assets have been deployed in the agreement and (2) the Company obtains substantially all of the economic benefits from the use of that underlying asset and directs how and for what purpose the asset is used during the term of the agreement. Amounts related to operating leases are included in “Right-of-use assets”, “Current maturities of operating lease liabilities” and “Operating lease liabilities, net of current maturities” in the condensed consolidated balance sheets. Amounts related to finance leases are included in “Property, plant and equipment, net”, “Current maturities of long-term debt”, and “Long-term debt, net of current maturities” in the condensed consolidated balance sheets.
ROU assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets are recognized at the commencement date and consist of the present value of remaining lease payments over the lease term, initial direct costs, prepaid lease payments less

any lease incentives. Operating lease liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. The Company uses the implicit rate, when readily determinable or the incremental borrowing rate based on the information available at commencement date to determine the present value of lease payments. The lease terms may include options to extend or terminate the lease which are recorded in the financial statements if it is reasonably certain that the Company will exercise such options. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Lease agreements with lease and non-lease components are accounted for separately. The Company does not recognize leases with terms of less than twelve months in the condensed consolidated balance sheets and will recognizesrecognize those lease payments in the condensed consolidated statements of operations on a straight-line basis over the lease term.

The Company leases offices, processing centers, warehouse spaces and, to a lesser extent, certain equipment. These leases have remaining terms of 1 year to 7 years, some of which have options to extend for up to 10 years and/or options to terminate within 1 year. The options to renew are not recognized as part of the Company’s ROU assets and operating lease liabilities as the Company is not reasonably certain that it will exercise these options.
Total operating lease expense, including short-term lease expense was $5.7$8.9 million and $6.2$12.3 million for the sixnine months ended JuneSeptember 30, 2019 and 2018, respectively.

(13)    Fair Value of Financial Instruments
Authoritative guidance on fair value measurements defines fair value, establishes a framework for measuring fair value and stipulates the related disclosure requirements. The Company follows a three-level hierarchy, under which the fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels, moving from quoted prices in active markets in (Level 1) to unobservable inputs in (Level 3).
Due to their highly liquid nature, the amount of the Company’s other financial instruments, including cash and cash equivalents, restricted cash, accounts and unbilled receivables, short term investments, accounts payable and accrued multi-client data library royalties, represent their approximate fair value.
The carrying amounts of the Company’s long-term debt as of JuneSeptember 30, 2019 and December 31, 2018 were $123.3$122.7 million and $124.7 million, respectively, compared to its fair values of $118.9$118.8 million and $120.7 million as of JuneSeptember 30, 2019 and December 31, 2018, respectively. The fair value of the long-term debtSecond Lien Notes was calculated using Level 1 inputs, including an active market price.
Fair value measurements are applied with respect to non-financial assets and liabilities on a non-recurring basis, which would consist primarily of goodwill, multi-client data library and property, plant and equipment.

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 “DigiFIN” and “Orca” refer to DigiFIN® andORCA® registered marks owned by ION, and the terms “Marlin,” “Marlin SmartPorts,” “Gator,” “SailWing,” and “4Sea” refers to the Marlin™, GATOR™Marlin SmartPorts™, Gator™, SailWing™ and 4Sea™ trademarks and service marks owned by ION.
We have been a technology leader for over 50 years with a strong history of innovation. While the traditional focus of our cutting-edge technology has been on the exploration and production (“E&P”) industry, we are now broadening and diversifying our business into relevant adjacent markets such as offshore logistics, port management, harbor security, defense and marine robotics.
Leveraging innovative technologies, we create value through data capture, analysis and optimization to enhance companies’ critical decision-making abilities and returns. Our offerings are focused on improving E&P decision-making and optimizing offshore operations. Our E&P offerings are designed to enable oil and gas companies to obtain higher resolution images of the Earth’s subsurface to reduce their risk in hydrocarbon exploration and development. We acquire, process and interpret data from seismic surveys on a multi-client or proprietary basis. Multi-client surveys are pre-funded, or underwritten, in part by our customers, and we contract with third 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 strategically located offices in 19 cities on six continents.offices.
Seismic imaging plays a fundamental role in hydrocarbon exploration and reservoir development by delineating structures, rock types and fluid locations in the subsurface. Our technologies and services are used by E&P companies to generate high-resolution images of the Earth’s subsurface to identify hydrocarbons and pinpoint drilling locations for wells and to monitor production from existing wells.
During the first quarter of 2019, we consolidated our operating segments from three into two, eliminating the separate presentation of our Ocean Bottom Integrated Technologies segment. This consolidation aligns with our asset light business model and evolved strategy to commercialize components of the Company’sour next generation ocean bottom nodal system, 4Sea, instead of operating a crew. We are offering 4Sea components more broadly to the growing number of OBS service providers under recurring revenue commercial strategies that will enable us to share in the value our technology delivers. We may also license the right to manufacture and use the 4Sea nodal technology to a service provider on a value-based pricing model, such as a royalty stream. Revenues from 4Sea would beare being recognized through the relevant segments, either E&P Technology & Services or Operations Optimization.
We provide our services and products through two business segments: E&P Technology & Services and Operations Optimization. In addition, we have a 49% ownership interest in our INOVA Geophysical Equipment Limited joint venture (“INOVA Geophysical” or “INOVA”).
The advanced technologies we currently offer include our Orca and Gator command and control software systems, Full Waveform Inversion (“FWI”) data processing technology, Marlin operations optimization software, and other technologies, each of which is designed to deliver improvements in image quality, safety and/or productivity. In 2017, we introduced our fully integrated ocean bottom nodal system, 4Sea, which is designed to deliver a step change in economics, QHSE performance and final image delivery time, creating more value for clients by providing data in time for critical reservoir decisions, such as determining drilling locations and informing enhanced recovery techniques.
We made significant headway on the commercialization of 4Sea and SailWing, which target one of the real growth segments in our industry. We signed a memorandum of understanding with iSEISMIC to deploy the complete 4Sea next generation ocean bottom system. In addition, we leased our first SailWing system and new rechargeable battery technology under recurring revenue business models.
We have approximately 500600 patents and pending patent applications in various countries around the world. Approximately 39%40% of our employees are in technical roles and over 19% of our employees have advanced degrees.
As of September 30, 2019, BGP Inc. (“BGP”) owns 10.6% of our outstanding common stock. BGP is a subsidiary of China National Petroleum Corporation, and is generally regarded as the world’s largest land geophysical service contractor.
E&P Technology & Services. Our E&P Technology & Services segment provides three distinct activities that often work together.
    

Our E&P Technology & Services segment creates digital data assets and delivers services to help E&P companies improve decision-making, reduce risk and maximize value. For example, E&P Technology & Services provides information to better understand new frontiers or complex subsurface geologies, how to maximize portfolio value, or how to optimize license round success and acreage values.
Our Ventures group leverages the world-class geoscience skills of both the Imaging Services and E&P Advisors groups to create global digital data assets that are licensed to multiple E&P companies to optimize their investment decisions. The global data library consists of over 637,000652,000 km of 2-D and 240,000250,000 sq. km of 3-D multi-client seismic data in virtually all major offshore petroleum provinces. Ventures provides services to manage multi-client or proprietary surveys, from survey planning and design to data acquisition and management, to final subsurface imaging and reservoir characterization. We focus on the technologically intensive components of the image development process, such as survey planning and design, and data processing and interpretation, while outsourcing asset-intensive components (such as field acquisition) to experienced contractors.
Our Imaging Services group offers data processing and imaging services designed to maximize image quality, helping E&P companies reduce exploration and production risk, evaluate and develop reservoirs, and increase production. Imaging Services develops subsurface images by applying its processing technology to data owned or licensed by its customers. We maintain approximately 19 petabytes of digital seismic data storage in four global data centers, including a core data center located in Houston.
Our E&P Advisors provide technical, commercial and strategic advice to host governments, E&P companies and private equity firms to evaluate oil and gas opportunities and/or assets worldwide, sharing in the value we create.
Operations Optimization. Our Operations Optimization segment develops mission-critical subscription offerings and provides engineering services that enable operational control and optimization offshore. This segment is comprised of our Optimization Software & Services and Devices offerings.
Our Optimization Software & Services group provides command and control software systems for marine towed streamer and ocean bottom seismic operations as well as survey design software and related services. Our Orca software is installed on towed streamer marine vessels worldwide, and our Gator software is used by ocean bottom surveyseismic crews. Our latest offering, Marlin is used to optimize offshore operations.operations, including a holistic digital management of ports and harbors operations through Marlin SmartPorts.
Our Devices group is engaged in the manufacture and repair of marine towed streamer positioning and control systems, analog geophone sensors and compasses, which have been deployed in marine robotics, scientific, E&P and other commercial applications.
Our team develops re-deployable OBS acquisition technology. We introduced our new fully integrated ocean bottom nodal system, 4Sea, in 2017. 4Sea is differentiated in its ability to deliver a step change in economics, QHSE performance and final image delivery time, creating more value for the client by providing information in time for critical decisions, such as determining drilling locations, fluid injections, and the like.
We are pursuing two asset light business models for commercializing our 4Sea technology that we believe will deliver a higher, more sustainable return over the long-term for our shareholders. The first is making the individual components of 4Sea available more broadly to all OBS service providers on a value-based pricing model, allowing us to participate in the success we enable. The second approach is to license the right to manufacture and use the 4Sea nodal technology to a service provider on a value-based pricing model, such as a royalty stream.
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. 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.
WesternGeco Litigation Update
Macroeconomic ConditionsOn August 30, 2019, the District Court refused WesternGeco’s request to reinstate the lost profits awards against us, and instead ordered a new trial to determine what lost profits, if any, WesternGeco is entitled to from surveys performed by our customers outside of the United States.
The District Court’s basis for granting the new trial as to lost profits was that, subsequent to the jury verdict that awarded lost profits, the Patent Trial and Appeal Board (“PTAB”) of the Patent and Trademark Office, in an administrative proceeding, invalidated four of the five patent claims that formed the basis for the lost profits judgment against us (that is, the PTAB held that those four patent claims should never have been granted), and the Court of Appeals and the Supreme Court both subsequently refused to overturn that finding. A trial date for the new trial has not yet been set.

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 economic growth, resource supply and demand, and commodity prices. Shale production dominated activity during the downturn due to its competitive break-even prices and short payback period compared to conventional exploration. Oil and gas projections suggest continued demand growth may create a supply gap in the middle of the next decade that production from US shale developments may be unable to meet, necessitating offshore exploration and development.  The decline rate in existing oil fields is about 10%, which can be reduced to about 5% per year with infill and other enhanced recovery techniques. Due to the time it takes to develop and start producing oil and gas from new discoveries offshore, there’s an increasing need to reinvest in conventional resources offshore to meet demand in the middle of the next decade. We’re starting to see increasing pressure for a resumption in offshore investment and exploration activity to replace reserves and existing production.
Third-party reports indicate that global exploration and production spending is expected to increase by 8% in 2019, consistent with 8% in 2018 and up from 4% growth in 2017. In addition, this is the second consecutive year that international spending is expected to increase, where our offerings are more relevant.

Oil prices rose pretty steadily in the first half of 2018 due to moderate global demand growth and continued OPEC production cut compliance, the combination of which resulted in relative market equilibrium. In late June 2018, OPEC voted to boost production to offset potential losses due to sanctions in Venezuela and Iran as well as underproduction by some OPEC countries. However, those shortage concerns quickly dissipated as supply started outpacing demand due to Iran sanction waivers and higher than expected United States production. Crude prices dropped to nearly $50 per barrel before the end of 2018, reflecting global oil inventory builds and at or near record levels of production from the world’s three largest producers - the United States, Saudi Arabia and Russia. The EIA forecasts the Brent crude oil spot price will average $67$59 per barrel in the second halffourth quarter of 2019 and remain at that level$60 per barrel in 2020, compared with an average of $71 per barrel in 2018. The slightlyEIA further noted that despite the recent increase in supply disruption due to attacks on major Saudi Arabian oil infrastructure, continued oil price pressure is expected as global inventories rise during the first half of 2020. The lower 2019 price forecast largely reflects uncertainty about the strength of global oil demand growth, which the EIA revised down from 1.4 to 1.1 mpbd this year. Slower oil demand growth, combined with strong supply growth in the United States, has helped build global oil inventories in the first half of 2019 and has limited any sustained upward pressure on oil prices. These factors have so far outweighed decreasing supply in Venezuela and Iran and the OPEC production cut extension through March of 2020.growth.
Given the historical volatility of crude prices, there is a continued risk that 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
We 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 reimaging programs as well as clients starting to renew interest in conventional offshore exploration. Generally, our revenue and EBITDA generation starts off slowly as customers set budgets in the first quarter, then picks up as they firm up plans throughout the year. 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 underwriting new projects. Our asset light strategy enables us to scale our business to market conditions avoiding significant fixed costs and maintaining flexibility to manage the timing and amount of our capital expenditures.
In our E&P Technology & Services segment, new venture revenues decreased compared to the secondthird quarter of 2018. This decrease was more than offset by the significant increase in our data library revenues. We invested $14.8$21.2 million in our

multi-client data library during the first halfthree quarters of 2019 and we expect investments in our multi-client data library to be in athe range of $35.0$30.0 million to $50.0$35.0 million for 2019 (a portion of which will be pre-funded or underwritten by our customers) compared to the $28.3 million invested in 2018.
As of JuneSeptember 30, 2019, our E&P Technology & Services segment backlog, which consists of commitments for (i) Imaging Services work, (ii) new venture projects (both multi-client and proprietary) by our Ventures group underwritten by our customers and (iii) E&P Advisor projects, was $30.2$24.8 million compared to $21.9 million at December 31, 2018 and $36.1$33.1 million at JuneSeptember 30, 2018. The majority of our backlog relates to our 2-D multi-client seismic programs and our proprietary Imaging Services work. We anticipate that the majority of our backlog will be recognized as revenue over the remainder of 2019.2019 and early 2020.
Within the Operations Optimization segment, both our Optimization Software & Services revenues and Devices revenues increased compared to the secondthird quarter of 2018.
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 attributes.

We intend that the following discussion of our financial condition and results of operations will provide information that will assist in understanding our condensed consolidated financial statements, the first halfchanges 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 2018.this financial information, additional meaningful comparisons between current results and results in prior operating periods. One such non-GAAP financial measure is Net loss attributable to ION as adjusted or adjusted net loss, which excludes certain charges or amounts. This adjusted net 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 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 for the year ended December 31, 2018, and (ii) Item 1A. “Risk Factors” in Part II of this Form 10-Q.

General, Administrative and Other Operating Expenses — General, administrative and other operating expenses were $25.6$36.6 million for the Current Period, an increase of $4.7$7.0 million, or 23%24%, compared to $20.9$29.6 million for the Comparable Period. This increase was primarily due to thean increase in compensation expense related to severance expense and stock appreciation rights awardscompensation expense.
Other Items
Interest Expense, net — Interest expense, net, was $6.2$9.4 million for the Current Period compared to $6.7$9.8 million for the Comparable Period. The decrease in interest expense resulted from lower outstanding debt during the Current Period. For additional information, please refer to “Liquidity and Capital Resources — Sources of Capital” below.

Income Tax Expense — Income tax expense for the Current Period was $4.1$7.9 million compared to $1.2$3.3 million for the Comparable Period. Our effective tax rates for the Current Period and Comparable Period were (16.2)(31.7)% and (2.9)(6.9)%, respectively. Our income tax expense for the Current Period and Comparable Periods,Period, were primarily related to results from our non-US businesses. Our effective tax rate for the Current Period and Comparable Period was negatively impacted by the change in valuation allowance related to U.S. operating losses for which we cannot currently recognize a tax benefit. See further discussion of establishment of the deferred tax valuation allowance at Footnote 7 “Income Taxes of Notes to Unaudited Condensed Consolidated Financial Statements.

Liquidity and Capital Resources
Sources of Capital
As of JuneSeptember 30, 2019, we had total liquidity of $67.6$65.5 million, consisting of $29.6$27.9 million of cash on hand and $38.0$37.6 million of available borrowing capacity under our 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 JuneSeptember 30, 2019, we had working capital of $(11.9)$(19.7) million. Excluding current maturities of operating lease liabilities, our working capital would have been $(0.1)$(8.1) million. Working capital requirements are primarily driven by our investment in our multi-client data library ($14.821.2 million in the Current Period and $35.0$30.0 million to $50.0$35.0 million for the full year)year, a portion of which will be pre-funded or underwritten by our customers) 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 requires cash expenditures for their salaries, bonuses, payroll taxes and related compensation expenses, including stock appreciation awards, typically in advance of related revenue billings and 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 Credit Facility.
Public Equity Offering and Retirement of Debt
On February 21, 2018, we completed a public equity offering to further delever our balance sheet.  We issued and sold 1,820,000 shares of common stock at a public offering price of $27.50 per share, and warrants to purchase an additional 1,820,000 shares of our common stock.  The net proceeds from this offering were $47.0 million, including transaction expenses.  A portion of the net proceeds were used to retire our $28.5 million Third Lien Notes in March 2018. The warrants have an exercise price of $33.60 per share, are immediately exercisable and were to expire on March 21, 2019.  On February 4, 2019, the Company extended expiration of the warrants to March 21, 2020.
Revolving Credit Facility
On August 16, 2018, we and our material U.S. subsidiaries — GX Technology Corporation, ION Exploration Products (U.S.A), Inc. and I/O Marine Systems, Inc. (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”) — the financial institutions party thereto, as lenders, and 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 “Third Amendment”), amending 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, dated as of August 4, 2015 and the Second Amendment to Revolving Credit and Security Agreement, dated as of April 28, 2016, the “Credit Agreement”). The Credit Agreement, as amended by the First Amendment, the Second Amendment and the Third Amendment is herein called the “Credit Facility”). The Third Amendment amended the Credit Agreement to, among other things:
extend the maturity date of the Credit Facility by approximately four years (from August 22, 2019 to August 16, 2023), subject to our retirement or extension of the maturity date of our Second Lien Notes, as defined below, which mature 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 borrower 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 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 the Borrowers’ multi-client data library. As of JuneSeptember 30, 2019, the undrawn borrowing base availability under the Credit Facility was $38.0$37.6 million, and there was no outstanding indebtedness under the Credit Facility. The maturity of the Credit Facility will accelerate to October 31, 2021 if we are unable to repay or extend the maturity of the Second Lien Notes.
The Credit Facility requires us to maintain compliance with various covenants. At JuneSeptember 30, 2019, we were in compliance with all of the covenants under the Credit Facility. For further information regarding our Credit Facility, see above Footnote 5 “Long-term Debt” of Footnotes to Condensed Consolidated Financial Statements.
Senior Secured Notes
As of JuneSeptember 30, 2019, ION Geophysical Corporation’s 9.125% Senior Secured Second Priority Notes due December 2021 (the “Second Lien Notes”) had an outstanding aggregate principal amount of $120.6 million and are senior secured second-priority obligations guaranteed by the Material U.S. Subsidiaries and the Mexican Subsidiary. Interest on the Second Lien Notes is payable semiannually in arrears on June 15 and December 15 of each year during their term, except that the interest payment otherwise payable on June 15, 2021 will be payable on December 15, 2021.
The April 2016 indenture governing the Second Lien Notes contains certain covenants that, among other things, limits or prohibits our ability and the ability of our restricted subsidiaries to take certain actions or permit certain conditions to exist during the term of the Second Lien Notes, including among other things, incurring additional indebtedness in excess of permitted indebtedness, creating liens, paying dividends and making other distributions in respect of our capital stock, redeeming our capital stock, making investments or certain other restricted payments, selling certain kinds of assets, entering into transactions with affiliates, and effecting mergers or consolidations. These and other restrictive covenants contained in the Second Lien Notes Indenture are subject to certain exceptions and qualifications. All of our subsidiaries are currently restricted subsidiaries.
At JuneSeptember 30, 2019, we were in compliance with all of the covenants under the Second Lien Notes.
On or after December 15, 2019, we may, on one or more occasions, redeem all or a part of the Second Lien Notes at the redemption prices set forth below, plus accrued and unpaid interest and special interest, if any, on the Second Lien Notes redeemed during the twelve-month period beginning on December 15th of the years indicated below:
Date Percentage
2019 105.50%
2020 103.50%
2021 and thereafter 100.00%
Meeting our Liquidity Requirements
As of JuneSeptember 30, 2019, our total outstanding indebtedness (including equipment finance leases) was approximately $120.8$120.5 million, consisting primarily of approximately $120.6 million outstanding Second Lien Notes, $2.4$2.1 million of equipment finance leases and other short-term debt, partially offset by $2.4$2.2 million of debt issuance costs. As of JuneSeptember 30, 2019, there was no outstanding indebtedness under our Credit Facility.
For the Current Period, total capital expenditures, including the investments in our multi-client data library, were $16.222.5 million. We expect that our capital expenditures related to investments in our multi-client data library this year to be in the range of $30.0 million to $35.0 million, to $50.0 million.a portion of which will be pre-funded or underwritten by our customers. We expect capital expenditures related to property, plant and equipment to be in the range of $3.0 million to $5.0 million in 2019.
We 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 twelve 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, financial condition and results of operations.
Cash Flow from Operations
In the Current Period, we generated $14.3$19.3 million of cash from operating activities compared to cash used from operating activities of $0.2$7.3 million for the Comparable Period. The increase was driven primarily by collections of our combined accounts and unbilled receivable balance and significantlyresulting from improved revenues in the Current Period.
    

Cash Flow from Investing Activities
Cash used in investing activities was $16.2$22.5 million in the Current Period compared to $14.2$20.2 million for the Comparable Period. The principal uses of cash in our investing activities during the Current Period were $14.8$21.2 million invested in our multi-client data library and $1.4$1.3 million for capital expenditures related to property, plant and equipment.
The principal use of cash in our investing activities during the Comparable Period were $13.8$19.9 million invested in our multi-client data library and $0.4$0.3 million for capital expenditures related to property, plant and equipment.
Cash Flow from Financing Activities
Net cash used in financing activities was $2.0$2.6 million in the Current Period, compared to $6.4$5.2 million of cash provided by financing activities in the Comparable Period. Cash used in financing activities was related to $1.4$2.0 million of payments of long-term debt, including equipment finance leases in the Current Period.
The net cash provided by financing activities during the Comparable Period was related to $47.2$47.0 million of net cash received from our equity offering, $29.7$30.1 million of payments of long-term debt, including equipment finance leases, and a $10.0 million repayment of our Credit Facility in the Comparable Period.
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 second half of our fiscal year.
Critical Accounting Policies and Estimates
Refer to our Annual Report on Form 10-K for the year ended December 31, 2018, for a complete discussion of our significant accounting policies and estimates.
Leases
On January 1, 2019, we adopted Accounting Standards Update (“ASU”) 2016-2, “Leases (Topic 842)” using the modified retrospective method. This ASU requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under the previous guidance. We used January 1, 2018, the beginning of the earliest comparative period presented in our condensed consolidated financial statements as our date of initial application. We elected the practical expedients upon transition which will retain the lease classification for leases and any unamortized initial direct costs that exist prior to the adoption of the standard.
The adoption of the standard resulted in $59.5 million and $70.6 million of right-of-use (“ROU”) assets and operating lease liabilities, respectively, on our condensed consolidated balance sheets as of January 1, 2018 and no impact on our condensed consolidated statements of operations and cash flows. The difference between the ROU assets and operating lease liabilities is due to the derecognition of $11.1 million in deferred rent recorded within other long-term liabilities. There was no impact on the condensed consolidated statements of operations and cash flows. The standard had no impact on our debt covenant compliance under existing agreements.
We determine if an arrangement is a lease at inception by considering whether (1) explicitly or implicitly identified assets have been deployed in the agreement and (2) we obtain substantially all of the economic benefits from the use of that underlying asset and directs how and for what purpose the asset is used during the term of the agreement. Amounts related to operating leases are included in “ROU“Right-of-use assets”, “Current maturities of operating lease liabilities” and “Operating lease liabilities, net of current maturities” in the condensed consolidated balance sheets. Amounts related to finance leases are included in “Property, plant and equipment, net”, “Current maturities of long-term debt”, and “Long-term debt, net of current maturities” in the condensed consolidated balance sheets.
ROU assets represent our right to use an underlying asset for the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets are recognized at commencement date and consist of the present value of remaining lease payments over the lease term, initial direct costs, prepaid lease payments less any lease incentives. Operating lease liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. We use the implicit rate, when readily determinable or the incremental borrowing rate based on the information available at commencement date to determine the present value of lease payments. The lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Lease agreements with lease and non-lease components are accounted for separately. We do not recognize leases with terms of less than twelve months on the condensed consolidated balance sheets and recognize those lease payments in the condensed consolidated statements of operations on a straight-line basis over the lease term. In the event that our assumptions and expectations change, we may have to revise our ROU assets and operating lease liabilities. See Note 2

Recent Accounting Pronouncements.” and Note 11 “Lease Obligations.of Notes to Condensed Consolidated Financial Statementsfor further discussion.

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 74%75% and 79%76%, respectively, of total net revenues.

Item 3. Quantitative and Qualitative Disclosures about Market Risk
Refer to Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2018 for a discussion regarding our quantitative and qualitative disclosures about market risk. There have been no material changes to those disclosures during the Current Period.
Item 4. Controls and Procedures
Disclosure Controls and Procedures. Disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file with or submit to the Securities and Exchange Commission (the “SEC”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time period specified by the SEC’s rules and forms. Disclosure controls and procedures are defined in Rule 13a-15(e) under the Exchange Act, and they include, without limitation, controls and procedures designed to ensure that information required to be disclosed under the Exchange Act is accumulated and communicated to management, including the principal executive officer and the principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.
Our management carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of JuneSeptember 30, 2019. Based upon that evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of JuneSeptember 30, 2019.
Changes in Internal Control over Financial Reporting. There was not any change in our internal control over financial reporting that occurred during the three months ended JuneSeptember 30, 2019, which has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
    

PART II — OTHER INFORMATION
Item 1. Legal Proceedings
WesternGeco
A moreIn June 2009, WesternGeco L.L.C. (“WesternGeco”) filed a lawsuit against us in depth treatment of the WesternGeco litigation and related proceedings is set forth above in Footnote 8 “Litigation” of Footnotes to Unaudited Condensed Consolidated Financial Statements. As noted in such Footnote, in 2014, because a jury found that we infringed four WesternGeco patents, the United States District Court for the Southern District of Texas (the “District Court”). In the lawsuit, styled WesternGeco L.L.C. v. ION Geophysical Corporation, WesternGeco alleged that we infringed four of their patents concerning marine seismic surveys.
Trial began in July 2012, and the jury returned a verdict in August 2012. The jury found that we infringed the six “claims” contained in four of WesternGeco’s patents by supplying our DigiFIN® lateral streamer control units from the United States. (In patent law, a “claim” is a technical legal term; an infringer infringes on one or more “claims” of a given patent.)
In May 2014, the District Court entered a Final Judgment against us in the amount of $123.8 million. The Final Judgment also enjoined us from supplying DigiFINs or any parts unique to DigiFINs in or from the United States. We conducted our business in compliance with the District Court’s orders, and has reorganized our operations such that we no longer supplies DigiFINs or any parts unique to DigiFINs in or from the United States.
As of 2018, we paid WesternGeco the $25.8 million of the Final Judgment (the portion of the judgment representing reasonable royalty damages and enhanced damages, plus interest).
However, as further described below, the balance of the judgment against us ($12.598.0 million, in reasonable royalties, $93.4 million inrepresenting lost profits $10.9 million in pre-judgment interest onfrom surveys performed by our customers outside of the United State, plus interest) has been vacated, and a new trial ordered, to determine what lost profits, and $9.4 million in supplemental damages).profit damages, if any, WesternGeco is entitled to.
On July 2, 2015,The Final Judgment was vacated after it was appealed to the United States Court of Appeals for the Federal Circuit in Washington, D.C. (the “Court of Appeals”) reversed, in part, the District Court, holding that the lost profits, which were attributable to foreign seismic surveys, were not available to WesternGeco under the Patent Act. We had recorded a loss contingency accrual of $123.8 million because of the District Court’s ruling. As a result of the reversal by the Court of Appeals, we reduced the loss contingency accrual to $22.0 million.
On November 14, 2016, the District Court ordered our sureties to pay principal and interest on the royalty damages previously awarded. On November 25, 2016, we paid WesternGeco the $20.8 million due pursuant, then to the order, and it reduced its loss contingency accrual to zero.
On March 14, 2017, the District Court held a hearing on whether to impose additional damages for willfulness. The Judge found that our infringement was willful, and awarded enhanced damages of $5.0 million to WesternGeco (WesternGeco had sought $43.6 million in such damages.) The District Court also ordered the appeal bond to be released and discharged. On June 30, 2017, we and WesternGeco agreed that neither would appeal the District Court's award of $5.0 million in enhanced damages. Upon assessment of the enhanced damages, we accrued $5.0 million in the first quarter of 2017 which was paid in full in 2018.
WesternGeco filed a petition in the Supreme Court on February 17, 2017, appealing the Court of Appeal’s decision that had eliminated lost profits. On January 12, 2018, the Supreme Court agreed to hear the appeal. The specific issue before the Supreme Court was whether 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 statute under which we were held to have infringed WesternGeco’s patents, and upon which the District Court and Court of Appeals relied in entering their rulings).
The Supreme Court heard oral arguments on April 16, 2018. We argued that the Court of Appeals’ decision that eliminated lost profits ought to be affirmed. WesternGeco and the U.S. 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, backagain, to the Court of Appeals for further proceedings consistent with its (the Supreme Court’s) opinion.
On July 27, 2018, the Court of Appeals vacated its earlier decision with respect to lost profits damages, and ordered WesternGeco and us to submit supplemental briefing on what relief would be appropriate in light of the Supreme Court’s decision.
We argued to the Court of Appeals that lost profits were not available to WesternGeco because the jury instructions required the jury to find that we had been WesternGeco’s direct competitor in the survey markets where WesternGeco had lost profits, and that the jury could not have found so. Additionally, we argued that the award of lost profits and reasonable royalties ought to be vacated and retried on separate grounds due to the outcome of an Inter Partes Review (“IPR”) filed with the Patent Trial and Appeal Board (“PTAB”) of the Patent and Trademark Office, in which the PTAB invalidated four of the six patent claims that formed the basis for the lawsuit judgment against the Company. (The Court of Appeals affirmed the PTAB’s findings, and on February 19, 2019, the Supreme Court declined to hear WesternGeco’s appeal on that issue.)Appeals.
On January 11, 2019, the Court of Appeals issued its ruling. In its ruling, the Court of Appeals refused to disturb the award of reasonable royalties to WesternGeco (which the Company paid in 2016), and rejected our “direct competitor” argument, but vacateddid not reinstate the District Court’s award of lost profits damages andaward; rather, the Court of Appeals remanded the case back to the District Court to determine whether to hold a new trial as to lost profits. The
On August 30, 2019, the District Court of Appeals also ruled that its affirmancerefused WesternGeco’s request to reinstate the lost profits awards against us, and instead ordered a new trial to determine what lost profits, if any, WesternGeco is entitled to from surveys performed by our customers outside of the PTAB’s decision eliminatedUnited States.
The District Court’s basis for granting the new trial as to lost profits was that, subsequent to the jury verdict that awarded lost profits, the Patent Trial and Appeal Board (“PTAB”) of the Patent and Trademark Office, in an administrative proceeding, invalidated four of the five patent claims that could have supportedformed the award ofbasis for the lost profits leaving only one remainingjudgment against us (that is, the PTAB held that those four patent claim that could support an award of lost profits.

Theclaims should never have been granted), and the Court of Appeals further heldand the Supreme Court both subsequently refused to overturn that the lost profits award can be reinstated by the District Court if the existingfinding. A trial record establishes thatdate for the jury must have found that the technology covered by the one remaining patent claim was essential for performing the surveys upon which lost profits were based. To make such a finding, the District Court must conclude that the present trial record establishes that there was no dispute that the technology covered by the one remaining patent claim, independent of the technology of the now-invalid claims, was required to perform the surveys. The Court of Appeals ruling further provides that if, but only if, the District Court concludes that WesternGeco established at trial, with undisputed evidence, that the remaining claim covers technology that was necessary to perform the surveys, then the District Court may deny a new trial and reinstate lost profits.
On February 19, 2019, we filed a motion for a new trial as to lost profits in the District Court. In the motion, we argued that a new trial on lost profits is necessary, since WesternGeco cannot demonstrate that it established, at trial, with undisputed evidence, that the one remaining patent claim covers technology that was necessary to perform the surveys upon which the lost profits award was based. On March 20, 2019, WesternGeco filed an opposition to our motion for a new trial, arguing that undisputed evidence established that the one remaining patent claim was necessary to perform the ten lost profits surveys. On that same date, WesternGeco filed a cross motion for entry of a judgment of $105.4 million in lost profits and pre- and post-judgment interest. We filed a reply to WesternGeco’s opposition motion on April 9, 2019 and an opposition to WesternGeco’s cross motion on April 18, 2019. On May 3, 2019, WesternGeco filed a reply in support of its cross motion for entry of judgment.has not yet been set.
We may not ultimately prevail in the litigation and we could be required to pay some or all of the lost profits that were awarded by the District Court, plus interest, if the District Court denies a new trial on lost profits, or if a new trial is granted and when a new judgment issues.issues in the new trial. 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 a significant loss contingency is probable, which could have a material effect on the Company’sour business, financial condition and results of operations. The Company’sOur 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, FootnoteNote 8 “Litigation” of FootnotesNotes to Unaudited Condensed Consolidated Financial Statements”.Statements.
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.
