Accounting Policies [Abstract]
Summary of Significant Accounting Policies	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, 2019, has been derived from the Company’s audited consolidated financial statements at that date. The condensed consolidated balance sheet at June 30, 2020, and the condensed consolidated statements of operations, condensed consolidated statements of comprehensive loss, condensed consolidated statements of stockholders' deficit for the three and six months ended June 30, 2020 and 2019 and the condensed consolidated statements of cash flows for the six months ended June 30, 2020 and 2019, 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) loss 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, 2019. Overview The COVID-19 pandemic caused the global economy to enter a recessionary period, which may be prolonged and severe, and significantly reduce the availability of capital and liquidity from banks and other providers of credit. The E&P industry is facing the double impact of demand destruction from COVID-19 and market oversupply from increased production, which caused oil and natural gas prices to decline significantly since the start of the year. Brent crude oil prices, which are most relevant to ION’s internationally focused business, dropped 66% during the first quarter from $66 on January 1, 2020 to $23 on March 31, 2020. Brent crude oil prices rebounded to $41 per barrel from increased global demand as pandemic restrictions started to ease and decreased production but remained significantly lower compared to the start of the year. The record production cut agreed to by OPEC and other oil producing countries in April was extended through July 2020. While commodity prices can be volatile, the sharp decline earlier this year triggered E&P companies to reduce budgets and delay near-term spending, but is also a catalyst to drive necessary cost restructuring and digital transformation of the E&P ecosystem. Onshore North America has had steeper declines than the international market, and the Company’s geographic focus is global offshore. Even so, the Company has already seen a material slowdown in offshore seismic activity and expect that the second half of 2020 have its challenges. The Company expects continued portfolio rationalization and high grading as E&P companies seek to find the best return on investment opportunities to meet oil and gas demand in the next decade. Near-term, due to the impact of the COVID-19, project high grading will likely be more acute due to budget cuts. The Company had already shifted its portfolio closer to reservoir, where revenue tends to be higher and more consistent. New Venture data acquisition offshore and Software and related personnel-based offshore services are expected to be most impacted by COVID-19 travel restrictions. While offshore operations will be temporarily impacted by travel restrictions, the Company believes the demand for digitalization technologies will remain strong. In some cases, ION technology is expected to be more relevant and valuable in the current environment, such as offerings that facilitate remote working. While the duration and extent of COVID-19 is difficult to predict, the Company’s first half revenues are greater than or equal to revenues in the comparable prior five years. There was a strong improvement in the Company’s cash balance from collection of accounts receivable related to its strong first quarter sales and realizing the additional cost reduction measures put in place entering the quarter as well as receiving government relief funding. The Company worked closely with its clients to understand revised budgets and to scale its business appropriately. To mitigate the impact of COVID-19 and oil price volatility, management implemented a plan to preserve cash and manage liquidity as follows: •Scaled down personnel costs and operating expenses in April 2020 by another $18.0 million during the remaining nine months of 2020, building on the over $20.0 million of cuts made in January 2020. These further reductions are primarily through a variety of furlough programs and reduced compensation arrangements across the Company’s worldwide workforce. The Company executives have taken a 20% base salary reduction and a tiered reduction scheme has been cascaded to the rest of the worldwide workforce. The Company’s Board of Directors have taken a 20% reduction in directors’ fees. In addition, the Company has curtailed use of external contractors, decreased travel and event costs and implemented new systems and processes that more efficiently support its business. •Reduced capital expenditures to an estimated $25.0 million to $35.0 million (a portion of which will be pre-funded or underwritten by the customers), down from the original budget of $35.0 million to $50.0 million, to reflect both reduced seismic demand and travel/border restrictions impacting new data acquisition offshore. This provides flexibility to aggressively reduce cash outflows while shifting to much lower cost reimaging programs. •Applied for various government assistance programs, of which approximately $7.0 million was received during the period. Receipt of this assistance allowed the Company to avoid further staff reductions while supporting its ongoing operations. •Re-negotiated existing lease agreements for its significant locations to obtain rent relief of approximately $4.0 million. The majority of the cash savings from the rent relief is expected to benefit the Company from July 2020 to March 2021. See Note 12 “Lease Obligations” for further details. •Announced the sale of its interest in INOVA Geophysical for $12.0 million that is expected to close during the fourth quarter of the year, subject to regulatory approvals and other closing conditions. •Entered into a settlement agreement with WesternGeco ending the decade-long patent litigation. See Note 9 “Litigation” for further details. •In addition, the Company reviewed its debt covenants and expects that it will remain in compliance for the next twelve months. The Company believes that the above management plan, which includes the use of government assistance programs, along with the Company’s existing cash balance, and the undrawn remaining borrowing capacity under its Credit Facility will be sufficient to meet the Company’s anticipated cash needs for the next twelve months. 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, 2019. There have been no changes in such policies or the application of such policies during the six months ended June 30, 2020 except as discussed in Note 2 “Recent Accounting Pronouncements.” 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 are not limited to, accounts and unbilled receivables, inventory valuation, sales forecast related to multi-client data library, impairment of property, plant and equipment and goodwill and deferred taxes. Actual results could materially differ from those estimates.
