SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The Consolidated Financial Statements include the accounts of TGC Industries, Inc. and its wholly-owned subsidiary, Eagle Canada, Inc. We have eliminated all significant intercompany accounts and transactions. Business Combinations We record acquisitions using the purchase method of accounting and, accordingly, have included the results of operations of acquired businesses in our consolidated results from the date of each acquisition. We allocate the purchase price of our acquisitions to the tangible assets, liabilities, and intangible assets acquired based on their estimated fair values. The excess purchase price over those fair values is recorded as goodwill. The fair value assigned to assets acquired is based on valuations provided by independent consultants and using management’s estimates and assumptions. Foreign Currency The functional currency of the Company’s international subsidiary is the local currency. Local currency assets and liabilities are translated at the rates of exchange on the balance sheet date, and local currency revenues and expenses are translated at average rates of exchange during the period. The resulting translation adjustments are recorded directly into a separate component of stockholders’ equity and represents the only component of accumulated other comprehensive income. Cash Equivalents The Company considers all highly liquid investments with original maturity dates of three months or less to be cash equivalents. The Company maintains its accounts at financial institutions located in Texas and Alberta, Canada. The Texas bank accounts are insured by the Federal Deposit Insurance Corporation up to $250,000. The Alberta bank accounts are insured by the Canadian Depository Insurance Corporation up to $100,000 Canadian dollars. Trade Accounts Receivable Trade accounts receivable are recorded in accordance with terms and amounts as specified in the related contracts on an ongoing basis. The Company evaluates the collectability of accounts receivable on a specific account basis using a combination of factors including the age of the outstanding balances, evaluation of the customer’s financial condition, and discussions with relevant Company personnel and with the customers directly. An allowance for doubtful accounts or direct write-off is recorded when it is determined that the receivable may not be collected, depending on the facts known and the probability of collection of the outstanding amount. Property and Equipment Property and equipment are stated at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the individual assets ranging from 1 to 7 years. The depreciation expense on assets acquired under capital leases is included with depreciation expense on owned assets. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred. Long-Lived Assets Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. For the purposes of evaluating the recoverability of long-lived assets, the recoverability test is performed using undiscounted cash flows estimated to be generated by those assets. No impairment charge was necessary at December 31, 2011, 2010, and 2009. Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases, in accordance with ASC Topic 740 (“Topic 740”). Deferred tax assets and liabilities are measured using enacted tax rates expected to be applied to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax expense or benefit is the result of changes in deferred tax assets and liabilities. The components of the deferred tax assets and liabilities are individually classified as current or non-current based on their characteristics. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Topic 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. In accordance with Topic 740, the Company recognizes in its financial statements the impact of a tax position if that position is “more likely than not” to be sustained on audit, based on the technical merits of the position. The Company’s estimate of the potential outcome of any uncertain tax issue is subject to management’s assessment of relevant risks, facts, and circumstances existing at that time. Topic 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, and disclosure. Interest and penalties related to unrecognized tax benefits, if any, are recorded as income tax expense. See Note I for further information. Revenue Recognition Seismic Surveys The Company provides seismic data acquisition survey services to its customers under general service agreements which define certain obligations for the Company and for its customers. A supplemental agreement setting forth the terms of a specific project, which may be cancelled by either party upon 30 days’ advance written notice, is entered into for every project. These supplemental agreements are either “turnkey” agreements providing for a fixed fee to be paid for each unit of seismic data acquired or “term” agreements providing for a fixed hourly, daily, or monthly fee during the term of the project. The duration of these projects will vary from a few days to several months. The Company recognizes revenue when services are performed under both types of agreements. Services are defined as the commencement of data acquisition which is the physical act of laying out seismic equipment or recording contractually determined data points. Under turnkey agreements, the total number of units of seismic data to be gathered is set forth in the agreement. TGC recognizes revenue on turnkey agreements, as services are performed on a per unit of seismic data acquired rate based on the number of data points per square mile obtained as compared to the number of square miles set forth in the agreement. Eagle Canada recognizes revenue on turnkey agreements as services are performed on a per unit of seismic data laid-out rate, which is standard industry practice in Canada based on the number of receiver lines laid out as compared to the estimated total lines to be laid out for the project pursuant to the agreement. Under term agreements, revenue is recognized, by both TGC and Eagle Canada, as services are performed based on the time worked rate provided in the term agreement. Under both turnkey and term agreements, cost of earned revenue is recognized by multiplying total estimated agreement cost by the percentage-of-completion of the agreement. The excess of that amount over the cost of earned revenue reported in prior periods is recognized as cost of earned revenue for the period. Agreements are not segmented nor combined for purposes of calculating percentage of completion. The asset “Cost and estimated earnings in excess of billings on uncompleted contracts” represents cost incurred on turnkey agreements in excess of billings on those agreements. The liability “Billings in excess of costs and estimated earnings on uncompleted contracts” represents billings on turnkey agreements in excess of cost on those agreements. Claims have been negligible in the years ended December 31, 2011, 2010, and 2009. Gravity Data The Company owns a data bank which contains gravity data, and to a lesser extent magnetic data, from many of the major oil and natural gas producing areas located within the U.S. When an order for gravity data is received, the portion of gravity data requested by the customer is prepared in digital format for licensing and shipment to the customer. This process is performed by an employee in the Company’s headquarters office and normally takes no longer than a few days. The licensing of gravity data is not a material part of the Company’s revenue. Gravity data revenue during the years ended December 31, 2011, 2010, and 2009, was approximately $37,500, $24,000, and $20,300, respectively. Reclassifications Certain reclassifications have been made to the 2010 financial statements to conform to the 2011 presentation. Share-Based Compensation The Company has two stock-based compensation plans, which are described more fully in Note H. The Company recognizes the fair value of the share-based compensation awards as wages in the Statements of Earnings on a straight-line basis over the vesting period. As a result, during the years ended December 31, 2011, 2010, and 2009, the Company recognized compensation expense for unvested stock options of $395,166, $422,024, and $179,918, respectively, and restricted stock of $28,603, $ 86,230, and $182,812, respectively. For the year ended December 31, 2011, the fair value of the single option grant was estimated on the date of the grant using the Binomial Lattice option pricing model with the following assumptions used for the outstanding grants: risk-free interest rate of 0.40%; expected dividend yield of 0.0%; expected life of 5.0 years; and expected volatility of 61.0%. No options were granted during the year ended December 31, 2010. For the year ended December 31, 2009, the fair value of each option grant was estimated on the date of the grant using the Binomial Lattice option pricing model with the following assumptions used for the outstanding grants: risk-free interest rate of 2.30%; expected dividend yields of 0.0%; expected lives of 5.0 years; and expected volatility of 95.0%. Financial Instruments The Company’s financial instruments recorded on the consolidated balance sheet include cash and cash equivalents, accounts receivable, accounts payable, and debt. The carrying amounts of cash and cash equivalents, accounts receivable, and accounts payable approximate fair value because of the short-term nature of these items. Fair value of long-term debt is based on rates available to the Company for debt with similar terms and maturities. Earnings Per Share Basic earnings per common share is based upon the weighted average number of shares of common stock outstanding. Diluted earnings per share is based upon the weighted average number of common shares outstanding and, when dilutive, common shares issuable for stock options, warrants, and convertible securities. All share and per share amounts for the years ended December 31, 2011, 2010 and 2009, have been adjusted to reflect 5% stock dividends paid May 14, 2010 and May 12, 2009 to shareholders of record as of April 30, 2010, and April 28, 2009, respectively. No stock dividends were declared or paid during the year ended December 31, 2011. Use of Estimates The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America 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. Actual results could differ from those estimates. Recent Accounting Standards In May 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards,” to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances disclosure requirements, particularly for Level 3 fair value measurements. ASU 2011-04 will be effective in our first quarter of 2012 and will be applied prospectively. We are currently evaluating the impact of ASU 2011-04 and believe the adoption will not have a material effect on our financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income,” to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. This update does not change what items are reported in other comprehensive income or the requirement to report reclassification of items from other comprehensive income to net income. ASU 2011-05 will be effective in our first quarter of 2012, though earlier adoption is permitted. The update will be applied retrospectively upon adoption. We believe the adoption will not have a material effect on our financial statements. In September 2011, the FASB issued ASU 2011-08, Intangibles-Goodwill and Other-Topic 350: Testing for Impairment. ASU 2011-08 amends the guidance in FASB Accounting Standards Codification Topic (“ASC”) 350-20, Intangibles-Goodwill and Other-Goodwill. The intent of this ASU is to simplify how entities test goodwill for impairment by allowing an entity to use a qualitative approach to test goodwill for impairment. The amendments in the ASU permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC 350-20. The amendments do not change the current guidance for testing other indefinite-lived assets for impairment. ASU 2011-08 is effective for goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early application is permitted. The Company elected to adopt this standard early and effective as of December 31, 2011 in its year-end goodwill impairment analysis. In December 2011, the FASB issued ASU No. 2011-11, Balance Sheet (Topic 210) — Disclosures about Offsetting Assets and Liabilities (“ASU 2011-11”). This update requires the following new disclosures related to recognized financial instruments (and derivatives) subject to master netting arrangements or similar agreements: (i) the gross amounts of recognized financial assets and liabilities; (ii) the amounts offset under current GAAP; (iii) the net amounts presented in the balance sheet; (iv) the amounts subject to an enforceable master netting arrangement or similar agreement that were not included in (ii); and (v) the net amount representing the difference between (iii) and (iv). The update also requires qualitative disclosures related to counterparties, setoff rights, and terms of enforceable master netting arrangements and related agreements depending on their effect or potential effect on the entity’s financial position. The new disclosures will enable financial statement users to compare balance sheets prepared under US GAAP and International Financial Reporting Standards (“IFRS”), which are subject to different offsetting models. ASU 2011-11 is effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. The Company does not currently expect that the adoption of this update in the first quarter of 2013 will have a significant effect on its consolidated financial statements and related disclosures.

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The Consolidated Financial Statements include the accounts of TGC Industries, Inc. and its wholly-owned subsidiary, Eagle Canada, Inc. We have eliminated all significant intercompany accounts and transactions.

Business Combinations

We record acquisitions using the purchase method of accounting and, accordingly, have included the results of operations of acquired businesses in our consolidated results from the date of each acquisition. We allocate the purchase price of our acquisitions to the tangible assets, liabilities, and intangible assets acquired based on their estimated fair values. The excess purchase price over those fair values is recorded as goodwill. The fair value assigned to assets acquired is based on valuations provided by independent consultants and using management’s estimates and assumptions.

Foreign Currency

The functional currency of the Company’s international subsidiary is the local currency. Local currency assets and liabilities are translated at the rates of exchange on the balance sheet date, and local currency revenues and expenses are translated at average rates of exchange during the period. The resulting translation adjustments are recorded directly into a separate component of stockholders’ equity and represents the only component of accumulated other comprehensive income.

Cash Equivalents

The Company considers all highly liquid investments with original maturity dates of three months or less to be cash equivalents. The Company maintains its accounts at financial institutions located in Texas and Alberta, Canada. The Texas bank accounts are insured by the Federal Deposit Insurance Corporation up to $250,000. The Alberta bank accounts are insured by the Canadian Depository Insurance Corporation up to $100,000 Canadian dollars.

Trade Accounts Receivable

Trade accounts receivable are recorded in accordance with terms and amounts as specified in the related contracts on an ongoing basis. The Company evaluates the collectability of accounts receivable on a specific account basis using a combination of factors including the age of the outstanding balances, evaluation of the customer’s financial condition, and discussions with relevant Company personnel and with the customers directly. An allowance for doubtful accounts or direct write-off is recorded when it is determined that the receivable may not be collected, depending on the facts known and the probability of collection of the outstanding amount.

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the individual assets ranging from 1 to 7 years. The depreciation expense on assets acquired under capital leases is included with depreciation expense on owned assets. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred.

Long-Lived Assets

Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. For the purposes of evaluating the recoverability of long-lived assets, the recoverability test is performed using undiscounted cash flows estimated to be generated by those assets. No impairment charge was necessary at December 31, 2011, 2010, and 2009.

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases, in accordance with ASC Topic 740 (“Topic 740”). Deferred tax assets and liabilities are measured using enacted tax rates expected to be applied to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax expense or benefit is the result of changes in deferred tax assets and liabilities. The components of the deferred tax assets and liabilities are individually classified as current or non-current based on their characteristics. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

Topic 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. In accordance with Topic 740, the Company recognizes in its financial statements the impact of a tax position if that position is “more likely than not” to be sustained on audit, based on the technical merits of the position. The Company’s estimate of the potential outcome of any uncertain tax issue is subject to management’s assessment of relevant risks, facts, and circumstances existing at that time. Topic 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, and disclosure. Interest and penalties related to unrecognized tax benefits, if any, are recorded as income tax expense. See Note I for further information.

Revenue Recognition

Seismic Surveys

The Company provides seismic data acquisition survey services to its customers under general service agreements which define certain obligations for the Company and for its customers. A supplemental agreement setting forth the terms of a specific project, which may be cancelled by either party upon 30 days’ advance written notice, is entered into for every project. These supplemental agreements are either “turnkey” agreements providing for a fixed fee to be paid for each unit of seismic data acquired or “term” agreements providing for a fixed hourly, daily, or monthly fee during the term of the project. The duration of these projects will vary from a few days to several months. The Company recognizes revenue when services are performed under both types of agreements. Services are defined as the commencement of data acquisition which is the physical act of laying out seismic equipment or recording contractually determined data points. Under turnkey agreements, the total number of units of seismic data to be gathered is set forth in the agreement. TGC recognizes revenue on turnkey agreements, as services are performed on a per unit of seismic data acquired rate based on the number of data points per square mile obtained as compared to the number of square miles set forth in the agreement. Eagle Canada recognizes revenue on turnkey agreements as services are performed on a per unit of seismic data laid-out rate, which is standard industry practice in Canada based on the number of receiver lines laid out as compared to the estimated total lines to be laid out for the project pursuant to the agreement. Under term agreements, revenue is recognized, by both TGC and Eagle Canada, as services are performed based on the time worked rate provided in the term agreement. Under both turnkey and term agreements, cost of earned revenue is recognized by multiplying total estimated agreement cost by the percentage-of-completion of the agreement. The excess of that amount over the cost of earned revenue reported in prior periods is recognized as cost of earned revenue for the period. Agreements are not segmented nor combined for purposes of calculating percentage of completion. The asset “Cost and estimated earnings in excess of billings on uncompleted contracts” represents cost incurred on turnkey agreements in excess of billings on those agreements. The liability “Billings in excess of costs and estimated earnings on uncompleted contracts” represents billings on turnkey agreements in excess of cost on those agreements. Claims have been negligible in the years ended December 31, 2011, 2010, and 2009.

Gravity Data

The Company owns a data bank which contains gravity data, and to a lesser extent magnetic data, from many of the major oil and natural gas producing areas located within the U.S. When an order for gravity data is received, the portion of gravity data requested by the customer is prepared in digital format for licensing and shipment to the customer. This process is performed by an employee in the Company’s headquarters office and normally takes no longer than a few days. The licensing of gravity data is not a material part of the Company’s revenue. Gravity data revenue during the years ended December 31, 2011, 2010, and 2009, was approximately $37,500, $24,000, and $20,300, respectively.

Reclassifications

Certain reclassifications have been made to the 2010 financial statements to conform to the 2011 presentation.

Share-Based Compensation

The Company has two stock-based compensation plans, which are described more fully in Note H. The Company recognizes the fair value of the share-based compensation awards as wages in the Statements of Earnings on a straight-line basis over the vesting period. As a result, during the years ended December 31, 2011, 2010, and 2009, the Company recognized compensation expense for unvested stock options of $395,166, $422,024, and $179,918, respectively, and restricted stock of $28,603, $ 86,230, and $182,812, respectively.

For the year ended December 31, 2011, the fair value of the single option grant was estimated on the date of the grant using the Binomial Lattice option pricing model with the following assumptions used for the outstanding grants: risk-free interest rate of 0.40%; expected dividend yield of 0.0%; expected life of 5.0 years; and expected volatility of 61.0%. No options were granted during the year ended December 31, 2010. For the year ended December 31, 2009, the fair value of each option grant was estimated on the date of the grant using the Binomial Lattice option pricing model with the following assumptions used for the outstanding grants: risk-free interest rate of 2.30%; expected dividend yields of 0.0%; expected lives of 5.0 years; and expected volatility of 95.0%.

Financial Instruments

The Company’s financial instruments recorded on the consolidated balance sheet include cash and cash equivalents, accounts receivable, accounts payable, and debt. The carrying amounts of cash and cash equivalents, accounts receivable, and accounts payable approximate fair value because of the short-term nature of these items. Fair value of long-term debt is based on rates available to the Company for debt with similar terms and maturities.

Earnings Per Share

Basic earnings per common share is based upon the weighted average number of shares of common stock outstanding. Diluted earnings per share is based upon the weighted average number of common shares outstanding and, when dilutive, common shares issuable for stock options, warrants, and convertible securities.

All share and per share amounts for the years ended December 31, 2011, 2010 and 2009, have been adjusted to reflect 5% stock dividends paid May 14, 2010 and May 12, 2009 to shareholders of record as of April 30, 2010, and April 28, 2009, respectively. No stock dividends were declared or paid during the year ended December 31, 2011.

Use of Estimates

The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America 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. Actual results could differ from those estimates.

Recent Accounting Standards

In May 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards,” to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances disclosure requirements, particularly for Level 3 fair value measurements. ASU 2011-04 will be effective in our first quarter of 2012 and will be applied prospectively. We are currently evaluating the impact of ASU 2011-04 and believe the adoption will not have a material effect on our financial statements.

In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income,” to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. This update does not change what items are reported in other comprehensive income or the requirement to report reclassification of items from other comprehensive income to net income. ASU 2011-05 will be effective in our first quarter of 2012, though earlier adoption is permitted. The update will be applied retrospectively upon adoption. We believe the adoption will not have a material effect on our financial statements.

In September 2011, the FASB issued ASU 2011-08, Intangibles-Goodwill and Other-Topic 350: Testing for Impairment. ASU 2011-08 amends the guidance in FASB Accounting Standards Codification Topic (“ASC”) 350-20, Intangibles-Goodwill and Other-Goodwill. The intent of this ASU is to simplify how entities test goodwill for impairment by allowing an entity to use a qualitative approach to test goodwill for impairment. The amendments in the ASU permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC 350-20. The amendments do not change the current guidance for testing other indefinite-lived assets for impairment. ASU 2011-08 is effective for goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early application is permitted. The Company elected to adopt this standard early and effective as of December 31, 2011 in its year-end goodwill impairment analysis.

In December 2011, the FASB issued ASU No. 2011-11, Balance Sheet (Topic 210) — Disclosures about Offsetting Assets and Liabilities (“ASU 2011-11”). This update requires the following new disclosures related to recognized financial instruments (and derivatives) subject to master netting arrangements or similar agreements: (i) the gross amounts of recognized financial assets and liabilities; (ii) the amounts offset under current GAAP; (iii) the net amounts presented in the balance sheet; (iv) the amounts subject to an enforceable master netting arrangement or similar agreement that were not included in (ii); and (v) the net amount representing the difference between (iii) and (iv). The update also requires qualitative disclosures related to counterparties, setoff rights, and terms of enforceable master netting arrangements and related agreements depending on their effect or potential effect on the entity’s financial position. The new disclosures will enable financial statement users to compare balance sheets prepared under US GAAP and International Financial Reporting Standards (“IFRS”), which are subject to different offsetting models. ASU 2011-11 is effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. The Company does not currently expect that the adoption of this update in the first quarter of 2013 will have a significant effect on its consolidated financial statements and related disclosures.
