Summary of Significant Accounting Policies
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. Summary of Significant Accounting Policies Organization and Nature of Operations The Company is a leading provider of onshore seismic data acquisition and processing services. Founded in 1952, the Company acquires and processes 2-D, 3-D and multi-component seismic data for its clients, ranging from major oil and gas companies to independent oil and gas operators as well as providers of multi-client data libraries. The Company operates in the lower 48 states of the U.S. and in Canada. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Dawson Operating LLC, Eagle Canada, Inc., Dawson Seismic Services Holdings, Inc., Eagle Canada Seismic Services ULC and Exploration Surveys, Inc. All significant intercompany balances and transactions have been eliminated in consolidation. Cash Equivalents For purposes of the financial statements, the Company considers demand deposits, certificates of deposit, overnight investments, money market funds and all highly liquid debt instruments purchased with an initial maturity of three months or less to be cash equivalents. Allowance for Doubtful Accounts Management determines the need for any allowance for doubtful accounts receivable based on its review of past-due accounts, its past experience of historical write-offs and its current client base. While the collectability of outstanding client invoices is continually assessed, the inherent volatility of the energy industry’s business cycle can cause swift and unpredictable changes in the financial stability of the Company’s clients. Property and Equipment Property and equipment is capitalized at historical cost or the fair value of assets acquired in a business combination and is depreciated over the useful life of the asset. Management’s estimation of this useful life is based on circumstances that exist in the seismic industry and information available at the time of the purchase of the asset. As circumstances change and new information becomes available, these estimates could change. Depreciation is computed using the straight-line method. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the balance sheet, and any resulting gain or loss is reflected in the results of operations for the period. Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment when triggering events occur suggesting deterioration in the assets’ recoverability or fair value. Recognition of an impairment charge is required if future expected undiscounted net cash flows are insufficient to recover the carrying value of the assets, and the fair value of the assets is below the carrying value of the assets. Management’s forecast of future cash flows used to perform impairment analysis includes estimates of future revenues and expenses based on the Company’s anticipated future results, while considering anticipated future oil and natural gas prices which is fundamental in assessing demand for the Company’s services. If the carrying amounts of the assets exceed the estimated expected undiscounted future cash flows, the Company measures the amount of possible impairment by comparing the carrying amount of the assets to the fair value. No impairment charges were recognized for the years ended December 31, 2019, 2018 and 2017. Leases The Company leases certain vehicles, seismic recording equipment, real property and office equipment under lease agreements. The Company evaluates each lease to determine its appropriate classification as an operating lease or finance lease for financial reporting purposes. The Company is the lessee in a lease contract when we obtain the right to control the asset. The majority of our operating leases are non-cancelable operating leases for office, shop and warehouse space in Midland, Plano, Denison, Houston, Denver, Oklahoma City and Calgary, Alberta. The assets and liabilities under finance leases are recorded at the lower of the present value of the minimum lease payments or the fair market value of the related assets. Assets under finance leases are amortized using the straight-line method over the initial lease term. Amortization of assets under finance leases is included in depreciation expense . In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) requiring organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Topic 842 also requires qualitative and quantitative disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. On January 1, 2019, the Company adopted Topic 842 using the optional cumulative-effect transition method of adoption, under which the new standards were applied prospectively rather than restating the prior periods presented. As a result, certain accounts lack a comparable value for the same period of 2018 and 2017, specifically accounts and values associated with operating leases and ROU assets. As a result of adopting the new standard, the Company recorded ROU assets and operating lease liabilities of approximately $7,769,000 and $8,252,000, respectively, on the consolidated balance sheet for 2019. The ROU assets equaled the operating lease liabilities, excluding the impact of reclassifying prepaid rent and deferred rent of approximately $14,000 and $497,000, respectively. These amounts were previously recorded in prepaid expenses and other current assets and other accrued liabilities, respectively. The new standard did not materially impact the Company’s results of operation or cash flows. In addition, the Company made an accounting policy election not to recognize leases with an initial term of 12 months or less and not to separate lease and non-lease components. The Company elected the practical expedients package, which among other things, allowed the Company to carry forward the historical lease classification. The Company did not elect the hindsight or land easement practical expedients. Several of the Company’s leases include options to renew, with renewal terms that can extend from one to 10 years or more. The exercise of lease renewal options is primarily at the Company’s discretion. To measure operating lease recognition, the Company evaluated its lease agreements to determine if they had economic incentives for renewal or options to purchase. The Company deems leasehold improvements as one of the few economic incentives that would entice the Company to renew a lease and all of its leasehold improvements are currently fully amortized. Where readily determinable, the Company uses the implicit interest rate in determining the present value of future minimum lease payments. In the absence of an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date. The Company gives consideration to its outstanding debt, as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. The Company’s ROU assets are amortized to operating lease cost over the lease terms on a straight-line basis. Intangibles The Company has intangible assets consisting primarily of trademarks/tradenames (which are not amortized) resulting from a business combination. The Company tests for impairment on an annual basis during the fourth quarter, and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. No impairment charges were recognized for the years ended December 31, 2019, 2018 and 2017. Revenue Recognition Services are provided under cancelable service contracts which usually have an original expected duration of one year or less. These contracts are either “turnkey” or “term” agreements. Under both types of agreements, the Company recognizes revenues as the services are performed. Revenue is generally recognized based on square miles of data recorded compared to total square miles anticipated to be recorded on the survey using the total estimated revenue for the service contract. In the case of a cancelled service contract, the client is billed and revenue is recognized for any third party charges and square miles of data recorded up to the date of cancellation. The Company receives reimbursements for certain out-of-pocket expenses under the terms of the service contracts. The amounts billed to clients are included at their gross amount in the total estimated revenue for the service contract. Clients are billed as permitted by the service contract. Contract assets and contract liabilities are the result of timing differences between revenue recognition, billings and cash collections. If billing occurs prior to the revenue recognition or billing exceeds the revenue recognized, the amount is considered deferred revenue and a contract liability. Conversely, if the revenue recognition exceeds the billing, the excess is considered an unbilled receivable and a contract asset. As services are performed, those deferred revenue amounts are recognized as revenue. In some instances, third-party permitting, surveying, drilling, helicopter, equipment rental and mobilization costs that directly relate to the contract are utilized to fulfill the contract obligations. These fulfillment costs are capitalized in other current assets and amortized based on the total square miles of data recorded compared to total square miles anticipated to be recorded on the survey using the total estimated fulfillment costs for the service contract. Estimates for total revenue and total fulfillment cost on any service contract are based on significant qualitative and quantitative judgments. Management considers a variety of factors such as whether various components of the performance obligation will be performed internally or externally, cost of third party services, and facts and circumstances unique to the performance obligation in making these estimates. In May 2014, the FASB issued new guidance related to revenue recognition in which an entity should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Codified as Topic 606, this new guidance also required disclosures sufficient to enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted Topic 606 effective January 1, 2018, using the full retrospective method, which required us to adjust our consolidated financial statements from amounts previously reported for each prior reporting period presented. The Company recognized the cumulative effect of adopting the guidance as an adjustment to its opening balance of retained earnings as of January 1, 2016. The Company elected several ongoing and transitional practical expedients including (i) to ignore the financing component when estimating the transaction price for service contracts completed within one year, (ii) to exclude sales tax collected from the customer when determining the transaction price, (iii) to expense incremental costs to obtain a customer contract if the amortization period for those costs would otherwise be one year or less, (iv) to not restate contracts that begin and end within the same annual reporting period, (v) to use the transaction price at the completion of the contract to retrospectively apply the new guidance, and (vi) to not disclose the remaining performance obligations for the reporting periods presented before the date of initial application. The most significant impact to the Company of the adoption of Topic 606 relates to the deferred recognition of revenues and expenses to fulfill contracts with customers until data recording has begun. Stock-Based Compensation The Company measures all stock-based compensation awards, which include stock options, restricted stock, restricted stock units and common stock awards, using the fair value method and recognizes compensation expense, net of actual forfeitures, as operating or general and administrative expense, as appropriate, in the Consolidated Statements of Operations and Comprehensive Loss on a straight-line basis over the vesting period of the related awards. Foreign Currency Translation The U.S. Dollar is the reporting currency for all periods presented. The functional currency of the Company’s foreign subsidiaries is generally the local currency. Any transactions denominated in a currency other than the functional currency are remeasured with the resulting unrealized gain or loss recognized in the Consolidated Statements of Operations and Comprehensive Loss as other income (expense). All assets and liabilities in the functional currency are then translated into U.S. Dollars at the exchange rate on the balance sheet date. Income and expenses are translated using the exchange rate applicable to each transaction. Equity transactions are translated using historical exchange rates. Adjustments resulting from translation are recorded as a separate component of accumulated other comprehensive income (loss) in the Consolidated Balance Sheets. Realized foreign currency transaction gains (losses) are included in the Consolidated Statements of Operations and Comprehensive Loss as other income (expense). Income Taxes The Company accounts for income taxes by recognizing amounts of taxes payable or refundable for the current year, and by using an asset and liability approach in recognizing the amount of deferred tax assets and liabilities for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. Management determines deferred taxes by identifying the types and amounts of existing temporary differences, measuring the total deferred tax asset or liability using the applicable tax rate in effect for the year in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates of deferred tax assets and liabilities is recognized in income in the year of an enacted rate change. The deferred tax asset is reduced by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized. Management’s methodology for recording income taxes requires judgment regarding assumptions and the use of estimates, including determining the annual effective tax rate and the valuation of deferred tax assets, which can create variances between actual results and estimates and could have a material impact on the Company’s provision or benefit for income taxes. Due to recent operating losses and valuation allowances, the Company may recognize reduced or no tax benefits on future losses on the Consolidated Statements of Operations and Comprehensive Loss. The Company’s effective tax rates differ from the statutory federal rate of 21% for certain items such as state and local taxes, valuation allowances, non-deductible expenses and discrete items. Use of Estimates in the Preparation of Financial Statements Preparation of the accompanying financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Because of the use of assumptions and estimates inherent in the reporting process, actual results could differ from those estimates. Reclassifications Certain reclassifications have been made to the year ended December 31, 2017 consolidated financial statements to conform to the 2019 presentation.

This reform changed the U.S. Statutory tax rate from 35% to 21% for tax years beginning after December 31, 2017. The Company was required to recognize the effect of the tax law changes in the period of enactment, such as remeasuring the domestic deferred tax assets and liabilities as well as reassessing the net realizability of deferred tax assets and liabilities. Due to the Company’s current loss position and valuation allowances, the tax reform did not have a material impact on its consolidated financial statements. In December 2017, the SEC staff issued Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allows companies to record provisional amounts during a measurement period not to extend beyond one year from the enactment date. The Tax Cuts and Jobs act was enacted in late fourth quarter of 2017 and provisional amounts were recorded. Subsequent guidance was received throughout the year and the accounting of deferred tax remeasurement was completed in accordance with SAB 118. Adjustments did not have a material impact on the Company’s consolidated financial statements due to the domestic loss position and the associated valuation allowances on the domestic deferred tax assets. The income tax provision (in thousands) differs from the amount computed by applying the statutory federal income tax rate to loss before income tax as follows: Year Ended December 31, 2019 2018 2017 Tax benefit computed at statutory rate of 21% and 35% (1) $ $ $ Change in valuation allowance State income tax benefit, net of federal tax Foreign loss Tax reform impact to deferred tax balances (2) — — Other Income tax benefit $ $ $ (1) Statutory rate of 21% for years ended December 31, 2019 and 2018 and 35% for year ended December 31, 2017. (2) Due to the Tax Cuts and Jobs Act enacted on December 22, 2017, the Company’s domestic deferred tax assets and liabilities were remeasured from 35% to 21% as of December 31, 2017. The change in tax rate resulted in a decrease to the gross domestic deferred tax asset which is offset by a corresponding decrease to the valuation allowance. The principal components of the Company’s net deferred tax assets (liabilities) (in thousands) are as follows: December 31, 2019 2018 Deferred tax assets: Federal tax net operating loss ("NOL") carryforward $ $ Foreign tax NOL carryforward State tax NOL carryforward Other comprehensive income Deferred revenue Restricted stock and restricted stock unit awards Foreign deferred taxes Right-of-use assets — Canadian start-up costs Self-insurance Workers’ compensation Alternative Minimum Tax ("AMT") credit carryforward Other Gross deferred tax assets Less valuation allowances Net deferred tax assets Deferred tax liabilities: Property and equipment Net deferred tax assets (liabilities) $ $ Domestic deferred tax assets $ $ Foreign deferred tax liabilities — Net deferred tax assets (liabilities) $ $ At December 31, 2019, the Company had a NOL for U.S. federal income tax purposes of approximately $123,434,000. This NOL will begin to expire in 2027. Losses incurred after the year ended December 31, 2017 have no expiration. The Company will carry forward the tax benefits related to federal NOL of approximately $25,921,000. The Company also had state NOL’s that will affect state taxes of approximately $1,692,000 at December 31, 2019. State NOL’s began to expire in 2015. The Company also had a Canadian NOL of $24,683,000 that will begin to expire in 2037. In evaluating the possible sources of taxable income during 2019, the Company determined it is more likely than not that the remaining deferred tax assets will not be realizable. As a result, the Company recorded full valuation allowance against foreign deferred tax assets and its federal and state deferred tax assets with the exception of its trademark intangible and the remaining AMT credit which will be refundable within the next three years. At December 31, 2019 and 2018, the Company did not have any uncertain tax positions. The Company’s policy is to recognize interest and penalties related to uncertain tax position in income tax expense.

The following weighted average numbers of stock options, restricted stock unit awards, and restricted stock awards, in each case as adjusted for the 5% stock dividend paid to shareholders on May 29, 2018, have been excluded from the calculation of diluted loss per share of common stock, as their effect would be anti-dilutive for the years ended December 31, 2019, 2018 and 2017: Year Ended December 31, 2019 2018 2017 Stock options 50,580 240,700 355,264 Restricted stock units 456,817 552,458 348,826 Restricted stock awards 8,133 67,052 76,960 Total 515,530 860,210 781,050

The Company disputes Weatherford’s allegations with respect to the Company and intends to vigorously defend itself in this case. Subsequent to the filing of the petition, Weatherford filed for bankruptcy protection on July 1, 2019. While the outcome and impact of this legal proceeding on the Company cannot be predicted with certainty, based on currently available information, management believes that the resolution of this proceeding will not have a material adverse effect on our financial condition, results of operations or liquidity. Additionally, the Company experiences contractual disputes with its clients from time to time regarding the payment of invoices or other matters. While the Company seeks to minimize these disputes and maintain good relations with its clients, the Company has experienced in the past, and may experience in the future, disputes that could affect its revenues and results of operations in any period. As of December 31, 2019, Veritex has issued two letters of credit under the Veritex Loan Agreement. The first letter of credit is in the amount of $1,767,000 to support payment of certain insurance obligations of the Company. The second letter of credit is in the amount of $583,000 to support the Company’s workers compensation insurance. Each of the letters of credit are secured by a certificate of deposit with Veritex .

Recently Issued Accounting Pronouncements	17. Recently Issued Accounting Pronouncements In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (“Topic 740”): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by eliminating certain exceptions to the general principles in Topic 740 and by clarifying and amending existing guidance to improve consistent application. This ASU is effective for the annual period beginning after December 15, 2020, including interim periods within that annual period. Certain amendments within this ASU are required to be applied on a retrospective basis for all periods presented; others are to be applied using a modified retrospective approach with a cumulative-effect adjustment to retained earnings, if any, as of the beginning of the first reporting period in which the guidance is adopted; and yet others are to be applied using either basis. All other amendments not specified in the ASU should be applied on a prospective basis. Early adoption is permitted. An entity that elects to early adopt in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period. Additionally, an entity that elects early adoption must adopt all the amendments in the same period. The Company is currently evaluating the new guidance to determine the impact it will have on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires entities to measure expected credit losses for certain financial assets using a new, forward-looking current expected credit loss model (“CECL”) that will result in the earlier recognition of allowances for losses. CECL is based on historical experience, adjusted for current conditions and reasonable and supportable forecasts. This ASU is effective for the annual period beginning after December 15, 2019, including interim periods within that annual period using a modified retrospective approach with a cumulative-effect adjustment to retained earnings for additional loss allowances, if any, as of the beginning of the first reporting period in which the guidance is adopted. The Company’s financial instruments within the scope of this guidance primarily includes trade receivables, and the Company does not expect a material impact on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07, Compensation – Stock Compensation (“Topic 718”): Improvements to Nonemployee Share-Based Payment Accounting, which expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees except for certain circumstances. Any transition impact will be a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption. This ASU is effective for the annual period beginning after December 15, 2018, including interim periods within that annual period and early adoption is permitted. The Company adopted this guidance in the first quarter of 2019 and it did not have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurement by removing, modifying, and adding certain disclosures. This ASU is effective for the annual period beginning after December 15, 2019, including interim periods within that annual period. The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements. In August 2018, the SEC adopted amendments to simplify certain disclosure requirements, as set forth in Securities Act Release No. 33-10532, Disclosure Update and Simplification, which includes a requirement for entities to present the changes in shareholders’ equity in the interim financial statements in quarterly reports on Form 10-Q. This amendment is effective for all filings made on or after November 5, 2018. In light of the timing of effectiveness of the amendment and proximity to the filing date for most filers’ quarterly reports, the SEC allowed for a filer’s first presentation of the changes in shareholders’ equity to be included in its Form 10-Q for the quarter that begins after the effective date. The Company adopted the SEC’s delayed implementation option and began presenting the changes in shareholders’ equity on an interim basis in the first quarter of 2019.

Concentrations of Credit Risk
Concentrations of Credit Risk	18. Concentrations of Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk at any given time may consist of cash and cash equivalents, restricted cash, money market funds and overnight investment accounts, short-term investments in certificates of deposit, trade and other receivables and other current assets. At December 31, 2019 and 2018, the Company had deposits with domestic and international banks in excess of federally insured limits. Management believes the credit risk associated with these deposits is minimal. Money market funds seek to preserve the value of the investment, but it is possible to lose money investing in these funds. The Company’s sales are to clients whose activities relate to oil and natural gas exploration and production. The Company generally extends unsecured credit to these clients; therefore, collection of receivables may be affected by the economy surrounding the oil and natural gas industry or other economic conditions. The Company closely monitors extensions of credit and may negotiate payment terms that mitigate risk.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Summary of Significant Accounting Policies
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Dawson Operating LLC, Eagle Canada, Inc., Dawson Seismic Services Holdings, Inc., Eagle Canada Seismic Services ULC and Exploration Surveys, Inc. All significant intercompany balances and transactions have been eliminated in consolidation.
Cash Equivalents	Cash Equivalents For purposes of the financial statements, the Company considers demand deposits, certificates of deposit, overnight investments, money market funds and all highly liquid debt instruments purchased with an initial maturity of three months or less to be cash equivalents.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts Management determines the need for any allowance for doubtful accounts receivable based on its review of past-due accounts, its past experience of historical write-offs and its current client base. While the collectability of outstanding client invoices is continually assessed, the inherent volatility of the energy industry’s business cycle can cause swift and unpredictable changes in the financial stability of the Company’s clients.
Property and Equipment	Property and Equipment Property and equipment is capitalized at historical cost or the fair value of assets acquired in a business combination and is depreciated over the useful life of the asset. Management’s estimation of this useful life is based on circumstances that exist in the seismic industry and information available at the time of the purchase of the asset. As circumstances change and new information becomes available, these estimates could change. Depreciation is computed using the straight-line method. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the balance sheet, and any resulting gain or loss is reflected in the results of operations for the period.
Impairment of Long-lived Assets	Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment when triggering events occur suggesting deterioration in the assets’ recoverability or fair value. Recognition of an impairment charge is required if future expected undiscounted net cash flows are insufficient to recover the carrying value of the assets, and the fair value of the assets is below the carrying value of the assets. Management’s forecast of future cash flows used to perform impairment analysis includes estimates of future revenues and expenses based on the Company’s anticipated future results, while considering anticipated future oil and natural gas prices which is fundamental in assessing demand for the Company’s services. If the carrying amounts of the assets exceed the estimated expected undiscounted future cash flows, the Company measures the amount of possible impairment by comparing the carrying amount of the assets to the fair value. No impairment charges were recognized for the years ended December 31, 2019, 2018 and 2017.
Leases	Leases The Company leases certain vehicles, seismic recording equipment, real property and office equipment under lease agreements. The Company evaluates each lease to determine its appropriate classification as an operating lease or finance lease for financial reporting purposes. The Company is the lessee in a lease contract when we obtain the right to control the asset. The majority of our operating leases are non-cancelable operating leases for office, shop and warehouse space in Midland, Plano, Denison, Houston, Denver, Oklahoma City and Calgary, Alberta. The assets and liabilities under finance leases are recorded at the lower of the present value of the minimum lease payments or the fair market value of the related assets. Assets under finance leases are amortized using the straight-line method over the initial lease term. Amortization of assets under finance leases is included in depreciation expense . In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) requiring organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Topic 842 also requires qualitative and quantitative disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. On January 1, 2019, the Company adopted Topic 842 using the optional cumulative-effect transition method of adoption, under which the new standards were applied prospectively rather than restating the prior periods presented. As a result, certain accounts lack a comparable value for the same period of 2018 and 2017, specifically accounts and values associated with operating leases and ROU assets. As a result of adopting the new standard, the Company recorded ROU assets and operating lease liabilities of approximately $7,769,000 and $8,252,000, respectively, on the consolidated balance sheet for 2019. The ROU assets equaled the operating lease liabilities, excluding the impact of reclassifying prepaid rent and deferred rent of approximately $14,000 and $497,000, respectively. These amounts were previously recorded in prepaid expenses and other current assets and other accrued liabilities, respectively. The new standard did not materially impact the Company’s results of operation or cash flows. In addition, the Company made an accounting policy election not to recognize leases with an initial term of 12 months or less and not to separate lease and non-lease components. The Company elected the practical expedients package, which among other things, allowed the Company to carry forward the historical lease classification. The Company did not elect the hindsight or land easement practical expedients. Several of the Company’s leases include options to renew, with renewal terms that can extend from one to 10 years or more. The exercise of lease renewal options is primarily at the Company’s discretion. To measure operating lease recognition, the Company evaluated its lease agreements to determine if they had economic incentives for renewal or options to purchase. The Company deems leasehold improvements as one of the few economic incentives that would entice the Company to renew a lease and all of its leasehold improvements are currently fully amortized. Where readily determinable, the Company uses the implicit interest rate in determining the present value of future minimum lease payments. In the absence of an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date. The Company gives consideration to its outstanding debt, as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. The Company’s ROU assets are amortized to operating lease cost over the lease terms on a straight-line basis.
Intangibles	Intangibles The Company has intangible assets consisting primarily of trademarks/tradenames (which are not amortized) resulting from a business combination. The Company tests for impairment on an annual basis during the fourth quarter, and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. No impairment charges were recognized for the years ended December 31, 2019, 2018 and 2017.
Revenue Recognition	Revenue Recognition Services are provided under cancelable service contracts which usually have an original expected duration of one year or less. These contracts are either “turnkey” or “term” agreements. Under both types of agreements, the Company recognizes revenues as the services are performed. Revenue is generally recognized based on square miles of data recorded compared to total square miles anticipated to be recorded on the survey using the total estimated revenue for the service contract. In the case of a cancelled service contract, the client is billed and revenue is recognized for any third party charges and square miles of data recorded up to the date of cancellation. The Company receives reimbursements for certain out-of-pocket expenses under the terms of the service contracts. The amounts billed to clients are included at their gross amount in the total estimated revenue for the service contract. Clients are billed as permitted by the service contract. Contract assets and contract liabilities are the result of timing differences between revenue recognition, billings and cash collections. If billing occurs prior to the revenue recognition or billing exceeds the revenue recognized, the amount is considered deferred revenue and a contract liability. Conversely, if the revenue recognition exceeds the billing, the excess is considered an unbilled receivable and a contract asset. As services are performed, those deferred revenue amounts are recognized as revenue. In some instances, third-party permitting, surveying, drilling, helicopter, equipment rental and mobilization costs that directly relate to the contract are utilized to fulfill the contract obligations. These fulfillment costs are capitalized in other current assets and amortized based on the total square miles of data recorded compared to total square miles anticipated to be recorded on the survey using the total estimated fulfillment costs for the service contract. Estimates for total revenue and total fulfillment cost on any service contract are based on significant qualitative and quantitative judgments. Management considers a variety of factors such as whether various components of the performance obligation will be performed internally or externally, cost of third party services, and facts and circumstances unique to the performance obligation in making these estimates. In May 2014, the FASB issued new guidance related to revenue recognition in which an entity should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Codified as Topic 606, this new guidance also required disclosures sufficient to enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted Topic 606 effective January 1, 2018, using the full retrospective method, which required us to adjust our consolidated financial statements from amounts previously reported for each prior reporting period presented. The Company recognized the cumulative effect of adopting the guidance as an adjustment to its opening balance of retained earnings as of January 1, 2016. The Company elected several ongoing and transitional practical expedients including (i) to ignore the financing component when estimating the transaction price for service contracts completed within one year, (ii) to exclude sales tax collected from the customer when determining the transaction price, (iii) to expense incremental costs to obtain a customer contract if the amortization period for those costs would otherwise be one year or less, (iv) to not restate contracts that begin and end within the same annual reporting period, (v) to use the transaction price at the completion of the contract to retrospectively apply the new guidance, and (vi) to not disclose the remaining performance obligations for the reporting periods presented before the date of initial application. The most significant impact to the Company of the adoption of Topic 606 relates to the deferred recognition of revenues and expenses to fulfill contracts with customers until data recording has begun.
Stock-Based Compensation	Stock-Based Compensation The Company measures all stock-based compensation awards, which include stock options, restricted stock, restricted stock units and common stock awards, using the fair value method and recognizes compensation expense, net of actual forfeitures, as operating or general and administrative expense, as appropriate, in the Consolidated Statements of Operations and Comprehensive Loss on a straight-line basis over the vesting period of the related awards.
Foreign Currency Translation	Foreign Currency Translation The U.S. Dollar is the reporting currency for all periods presented. The functional currency of the Company’s foreign subsidiaries is generally the local currency. Any transactions denominated in a currency other than the functional currency are remeasured with the resulting unrealized gain or loss recognized in the Consolidated Statements of Operations and Comprehensive Loss as other income (expense). All assets and liabilities in the functional currency are then translated into U.S. Dollars at the exchange rate on the balance sheet date. Income and expenses are translated using the exchange rate applicable to each transaction. Equity transactions are translated using historical exchange rates. Adjustments resulting from translation are recorded as a separate component of accumulated other comprehensive income (loss) in the Consolidated Balance Sheets. Realized foreign currency transaction gains (losses) are included in the Consolidated Statements of Operations and Comprehensive Loss as other income (expense).
Income Taxes	Income Taxes The Company accounts for income taxes by recognizing amounts of taxes payable or refundable for the current year, and by using an asset and liability approach in recognizing the amount of deferred tax assets and liabilities for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. Management determines deferred taxes by identifying the types and amounts of existing temporary differences, measuring the total deferred tax asset or liability using the applicable tax rate in effect for the year in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates of deferred tax assets and liabilities is recognized in income in the year of an enacted rate change. The deferred tax asset is reduced by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized. Management’s methodology for recording income taxes requires judgment regarding assumptions and the use of estimates, including determining the annual effective tax rate and the valuation of deferred tax assets, which can create variances between actual results and estimates and could have a material impact on the Company’s provision or benefit for income taxes. Due to recent operating losses and valuation allowances, the Company may recognize reduced or no tax benefits on future losses on the Consolidated Statements of Operations and Comprehensive Loss. The Company’s effective tax rates differ from the statutory federal rate of 21% for certain items such as state and local taxes, valuation allowances, non-deductible expenses and discrete items.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements Preparation of the accompanying financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Because of the use of assumptions and estimates inherent in the reporting process, actual results could differ from those estimates.
Reclassifications	Reclassifications Certain reclassifications have been made to the year ended December 31, 2017 consolidated financial statements to conform to the 2019 presentation. These reclassifications had no impact on the
