NOTE 6 - INCOME TAXES

The Company provides for income taxes during interim periods based on an estimate of the effective tax rate for the year.  Discrete items and changes in the estimate of the annual effective tax rate are recorded in the period in which they occur.

The Company assesses the likelihood that deferred tax assets will be recovered from the existing deferred tax liabilities or future taxable income in each jurisdiction.  To the extent the Company believes that recovery is not likely, it establishes a valuation allowance.  The Company has recorded valuation allowances in several non-US jurisdictions for its net deferred tax assets since management believes it is more likely than not that these assets will not be realized because the future taxable income necessary to utilize these losses cannot be established, projected, or the Company no longer has operations in these jurisdictions.

The effective income tax rate for the six months ended June 30, 2011 and 2010 was 58.7% and 41.8%, respectively.

The Company’s effective income tax rate in 2011 and 2010 differs from the federal statutory rate primarily due to state income taxes, non-deductible expenses, tax rate differential from US operations, and valuation allowances in non-US jurisdictions.

NOTE 7 - LONG-TERM DEBT

Senior Notes: On April 22, 2010, the Company entered into a Purchase Agreement (the “Purchase Agreement”) with Barclays Capital Inc., Credit Suisse Securities (USA) LLC and Banc of America Securities LLC, as representatives of the initial purchasers (the “Initial Purchasers”), relating to the offer and sale by the Company of $200 million aggregate principal amount of its 10.5% senior notes due 2017 (the “Notes”).  The Company’s net proceeds from the offering were approximately $188.1 million after deducting the Initial Purchasers’ discounts, offering expenses and original issue discount. The issuance of the Notes occurred on April 27, 2010. The Notes were offered and sold to the Initial Purchasers and resold only to qualified institutional buyers in compliance with the exemption from registration provided by Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and in offshore transactions in reliance on Regulation S under the Securities Act.

The Notes are a general unsecured, senior obligation of the Company. The Notes are unconditionally guaranteed as to principal, premium, if any, and interest by the Company’s domestic subsidiaries (the “Guarantors”) on a senior unsecured basis. (See Note 15)

The Company used the proceeds from the offering and sale of the Notes to repay outstanding indebtedness and plans to use the remaining proceeds for anticipated capital expenditures and for general working capital purposes.

On April 27, 2010, in connection with the offering of the Notes, the Company entered into (i) an Indenture with The Bank of New York Mellon Trust Company, N.A., (the “Trustee”), and (ii) a Registration Rights Agreement with the Initial Purchasers. The following is a brief summary of the material terms and conditions of the Indenture and the Registration Rights Agreement.

The Company and the Guarantors entered into an Indenture with the Trustee, pursuant to which the Company issued the Notes at a price equal to 97.009% of their face value.

Interest — The Notes will bear interest from April 27, 2010 at a rate of 10.5% per annum. The Company will pay interest on the Notes semi-annually, in arrears, on May 1 and November 1 of each year, beginning November 1, 2010.

10

Principal and Maturity — The Notes were issued with a $200 million aggregate principal amount and will mature on May 1, 2017.

Optional Redemption by the Company — At any time prior to May 1, 2013, the Company may redeem up to 35% of the aggregate principal amount of the Notes with the net cash proceeds of certain equity offerings at a redemption price of 110.500% of the aggregate principal amount of the Notes redeemed if at least 65% of the aggregate principal amount of the Notes remains outstanding immediately after such redemption and the redemption occurs within 90 days of the closing date of such equity offering. On or after May 1, 2014, the Company may redeem the Notes at the following percentages of the original principal amount: (i) 105.250% from May 1, 2014 to April 30, 2015; (ii) 102.625% from May 1, 2015 to April 30, 2016; and (iii) 100% from May 1, 2016 and thereafter.

Repurchase Obligations by the Company — If there is a change of control of the Company (as defined in the Indenture), each holder of the Notes may require the Company to purchase their Notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase.

Events of Default — The Indenture also contains events of default including, but not limited to, the following: (i) nonpayment; (ii) defaults in certain other indebtedness of the Company or the Guarantors; and (iii) the failure of the Company or the Guarantors to comply with their respective covenants in the event of a mandatory redemption, optional redemption, option to repurchase, or a merger, consolidation or sale of assets. Upon an event of default, the holders of the Notes or the Trustee may declare the Notes due and immediately payable. As of June 30, 2011, the Company is in compliance with all respective covenants.

Debt Issuance Costs: The costs related to the issuance of debt are capitalized and amortized to interest expense using the effective interest method over the maturity period of the related debt. Accumulated amortization is $712,093 and $396,248 at June 30, 2011 and December 31, 2010, respectively.

Bank of America Revolving Credit Facility: On April 30, 2010, the Company entered into a revolving credit facility under the terms of a Credit Agreement (the “Revolving Credit Facility”) with Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer, and each lender from time to time party thereto. The Revolving Credit Facility provided for borrowings of up to $50.0 million. The loans under the Revolving Credit Facility bear interest at a rate equal to LIBOR plus the Applicable Rate or the Base Rate plus the Applicable Rate. The Base Rate is defined as the higher of (x) the prime rate and (y) the Federal Funds rate plus 0.50%. The Applicable Rate is defined as a percentage determined in accordance with a pricing grid based upon the Company’s leverage ratio, that will decline from LIBOR plus 4.00% or the prime rate plus 3.00% to a minimum rate equal to LIBOR plus 3.50% or the prime rate plus 2.50%. The Company is able to prepay borrowings under the Revolving Credit Facility at any time without penalty or premium, subject to reimbursement of the lenders’ breakage and redeployment costs in the case of prepayment of LIBOR borrowings. The Company also will pay a commitment fee of 0.75% per annum on the actual daily unused portions of the Revolving Credit Facility.

The Company’s Revolving Credit Facility is secured by a first priority lien on substantially all of the Company’s assets, the assets of the Company’s non-foreign subsidiaries, the stock of the Company’s non-foreign subsidiaries and 66% of the stock of certain of the Company’s foreign subsidiaries. In addition, the Company’s non-foreign subsidiaries will guarantee the Company’s obligations under the Revolving Credit Facility.

The terms of the Revolving Credit Facility will limit the Company’s ability and the ability of certain of the Company’s subsidiaries to, among other things: incur or guarantee additional indebtedness; grant additional liens on the Company’s assets; make certain investments or certain acquisitions of substantially all or a portion of another entity’s business or assets; merge with another entity or dispose of the Company’s assets; pay dividends; enter into transactions with affiliates; engage in other lines of business and repurchase stock.

11

Additionally, the Revolving Credit Facility requires that the Company maintain certain ratios of total senior, secured debt to consolidated EBITDA (as defined therein), and of consolidated EBITDA to consolidated interest. The Revolving Credit Facility includes customary provisions with respect to events of default. Upon the occurrence and continuation of an event of default under the Revolving Credit Facility, the lenders will be able to, among other things, terminate their revolving loan commitments, accelerate the repayment of the loans outstanding and declare the same to be immediately due and payable. As of June 30, 2011, the Company is in compliance with all respective covenants.

On June 9, 2011, the Company amended the Revolving Credit Facility to provide for borrowings of up to $70.0 million under substantially similar terms.

In connection with the closing of the Company’s initial public offering and the sale of $200 million of the Company’s 10.5% senior notes due 2017 on April 27, 2010, the Company repaid all outstanding borrowings under the First Lien Credit Agreement, the Second Lien Credit Agreement, and the Construction Loan Agreement. These repayments resulted in the termination of each of these borrowing arrangements. The prepayment of the Construction Loan Agreement resulted in the incurrence of $160,000 in prepayment penalties.

Promissory Notes: In April 2011, in exchange for insurance services provided, the Company issued two negotiable promissory notes for $1,360,642 and $512,005 at interest rates of 3.05% and 3.19% per annum, respectively. The notes are due March 21, 2012 and January 8, 2012, respectively. In June 2011, the Company issued three promissory notes to three financial institutions in Colombia for $3,193,880 at interest rates ranging from 6.7% to 7.2%. The notes are due in August 2011.

Letter of Credit Facility:  In February 2007, the Company entered into a $10 million revolving line of credit which is secured by restricted cash.  The terms of the letter of credit facility as currently written only allow for letters of credit to be drawn on the available credit; however, the cash balance in excess of the total outstanding letters of credit may be withdrawn at any time.  As of June 30, 2011 and December 31, 2010, the letters of credit outstanding were $5,159,061 and $2,432,700, respectively.

Long-term debt consisted of the following:

NOTE 8 – CAPITAL LEASE

In April 2011, the Company entered into a sale and leaseback transaction for certain seismic equipment that is accounted for as a capital lease, with an interest rate of 5.25% per year. The Company received proceeds of $7,715,520 and will make monthly payments until the maturity date of May 2013. The balance as of June 30, 2011 is $6,734,689.

NOTE 9 – FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company follows current guidance as it relates to financial assets and financial liabilities, which defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles and expands disclosures about fair value measurements.  The provisions of this standard apply to other accounting pronouncements that require or permit fair value measurements.

This guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.   Hierarchical levels, as defined in this guidance and directly related to the amount of subjectivity associated with the inputs to fair valuations of these assets and liabilities are as follows:

Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 – Inputs that are both significant to the fair value measurement and unobservable.

The reported fair values for financial instruments that use Level 2 and Level 3 inputs to determine fair value are based on a variety of factors and assumptions. Accordingly, certain fair values may not represent actual values of the financial instruments that could have been realized as of June 30, 2011 or that will be realized in the future and do not include expenses that could be incurred in an actual sale or settlement.

In the normal course of operations, the Company is exposed to market risks arising from adverse changes in interest rates.  Market risk is defined for these purposes as the potential for change in the fair value of debt instruments resulting from an adverse movement in interest rates.

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and current debt approximate their fair value due to the short maturity of those instruments, and therefore, have been excluded from the table below.  The fair value of the Notes is determined by multiplying the principal amount by the market price.  The following table sets forth the fair value of the Company’s financial assets and liabilities as of June 30, 2011 and December 31, 2010:

	June 30, 2011				December 31, 2010
	(unaudited)
	Carrying		Fair		Carrying		Fair
	Amount		Value		Amount		Value
Long-term debt	$	194,737,270	$	215,000,000	$	194,418,242	$	198,250,000

13

The Company is not a party to any hedge arrangements, commodity swap agreements or other derivative financial instruments.

The Company utilizes foreign subsidiaries and branches to conduct operations outside of the United States. These operations expose the Company to market risks from changes in foreign exchange rates.

NOTE 10 - STOCK-BASED COMPENSATION

The Company follows the current guidance for share-based payments which requires all stock-based payments, including stock options, to be recognized as an operating expense over the vesting period, based on their grant date fair values.

In July 2006, the Company’s board of directors and stockholders adopted the Global Geophysical Services, Inc. 2006 Incentive Compensation Plan (the “2006 Incentive Plan”).  The 2006 Incentive Plan provides for a variety of  incentive awards, including nonstatutory stock options, incentive stock options within the meaning of Section 422 of the Internal Revenue Code, or (the “Code”), stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based awards, and other stock-based awards.  A total of 9,203,058 shares of common stock are reserved for issuance under the 2006 Incentive Plan.  As of June 30, 2011, a total of 4,830,400 options have been granted and 2,068,200 have been forfeited.

Incentive Stock Options:  The Company estimates the fair value of each stock option on the date of grant using the Black-Scholes-Merton valuation model.  The volatility is based on expected volatility over the expected life of eighty-four months.  As the Company has not historically declared dividends, the dividend yield used in the calculation is zero. Actual value realized, if any, is dependent on the future performance of the Company’s common stock and overall stock market conditions.  There is no assurance the value realized by an optionee will be at or near the value estimated by the Black-Scholes-Merton model.

The following assumptions were used:

	Six Months Ended
	June 30,
	2011			2010
Risk-free interest rates		2.68	%		3.05	%
Expected lives (in years)		7.00			7.00
Expected dividend yield		0.00	%		0.00	%
Expected volatility		59.08	%		59.09	%

The computation of expected volatility during the three and six months ended June 30, 2011 and 2010 was based on the historical volatility. Historical volatility was calculated from historical data for the time approximately equal to the expected term of the option award starting from the grant date. The risk-free interest rate assumption is based upon the U.S. Treasury yield curve in effect at the time of grant for the period corresponding with the expected life of the option.

NOTE 14 – RECENTLY ISSUED ACCOUNTING STANDARDS

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04, “Fair Value Measurements (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS,” (“ASU 2011-04”). ASU 2011-04 changes the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements to ensure consistency between U.S. GAAP and International Financial Reporting Standards (“IFRS”). ASU 2011-04 also expands the disclosures for fair value measurements that are estimated using significant unobservable (Level 3) inputs. This new guidance is to be applied prospectively. ASU 2011-04 will be effective for interim and annual periods beginning after Dec. 15, 2011, with early adoption permitted. We believe that the adoption of this standard will not materially expand our consolidated financial statement footnote disclosures.

NOTE 15 – GUARANTEES OF REGISTERED SECURITIES

On August 3, 2010, the Company filed a registration statement on Form S-4 with the Securities and Exchange Commission. Under this registration statement, the Company exchanged $200 million of its publicly registered 10.50% senior notes due 2017 for a like amount of its privately placed 10.50% senior notes due 2017. The debt securities sold are fully and unconditionally guaranteed, on a joint and several basis, by the guarantor subsidiaries which will correspond to all subsidiaries located in the United States. The non-guarantor subsidiaries consist of all subsidiaries outside of the United States.

Separate condensed consolidating financial statement information for the guarantor subsidiaries and non-guarantor subsidiaries as of June 30, 2011 and December 31, 2010 and for the three and six months ended June 30, 2011 and 2010 is as follows:

NOTE 16 - SUBSEQUENT EVENTS

The Company evaluates events and transactions that occur after the balance sheet date but before the consolidated financial statements are issued. The Company evaluated such events and transactions through the date when the consolidated financial statements were filed electronically with the Securities and Exchange Commission.

Item 2.   Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in combination with our Interim Financial Statements contained in this Form 10-Q and our Financial Statements for the year ended December 31, 2010 included in our form 10-K (Commission file number: 001-34709).

Forward Looking Statements

Statements other than statements of historical fact included in this Form 10-Q that relate to forecasts, estimates or other expectations regarding future events regarding technological advancements and our financial position, business strategy and plans and objectives of our management for future operations, may be deemed to be forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. When used in this Form 10-Q, words such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan” and similar expressions, as they relate to us or our management, identify forward-looking statements. Forward-looking statements include, but are not limited to, statements about business outlook for the year, backlog and bid activity, business strategy, and related financial performance and statements with respect to future events.  Such forward-looking statements are based on certain assumptions made by the Company based on management’s experience and perception of historical trends, industry conditions, market position, future operations, profitability, liquidity, backlog, capital resources and other information currently available to management and believed to be appropriate. Actual results could differ materially from those contemplated by the forward-looking statements as a result of certain factors, including but not limited to, the volatility of oil and natural gas prices, disruptions in the global economy, dependence upon energy industry spending, delays, reductions or cancellations of service contracts, high fixed costs of operations, weather interruptions, inability to obtain land access rights of way, industry competition, limited number of customers, credit risk related to our customers, asset impairments, the availability of capital resources, and operational disruptions. A discussion of these factors, including risks and uncertainties, is set forth under “Risk Factors” in our form 10-K (Commission file number: 001-34709) filed with the Securities and Exchange Commission. These forward-looking statements reflect our current views with respect to future events and are subject to these and other risks, uncertainties and assumptions relating to our operations, results of operations, growth strategies and liquidity. Although the Company believes that the expectations reflected in such statements are reasonable, the Company can give no assurance that such expectations will be correct.  All subsequent written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified by these cautionary statements and any other cautionary statements that may accompany such forward-looking statements. We assume no obligation to update any such forward-looking statements.

Our backlog estimates represent those seismic data acquisition projects for which a client has executed a contract and has a scheduled start date for the project as well as unrecognized pre-committed funding from our Multi-client Services segment. Backlog estimates are based on a number of assumptions and estimates including assumptions related to foreign exchange rates and proportionate performance of contracts and our valuation of assets, such as seismic data, to be received by us as payment under certain agreements. The realization of our backlog estimates is further affected by our performance under term rate contracts, as the early or late completion of a project under term rate contracts will generally result in decreased or increased, as the case may be, revenues derived from these projects. Contracts for services are also occasionally modified by mutual consent. Because of potential changes in the scope or schedule of our clients' projects, we cannot predict with certainty when or if our backlog will be realized. Even where a project proceeds as scheduled, it is possible that the client may default and fail to pay amounts owed to us. In addition, the contracts in our backlog are cancelable by the client. Material delays, payment defaults or cancellations could reduce the amount of backlog currently reported, and consequently, could inhibit the conversion of that backlog into revenues.

Overview

We provide an integrated suite of seismic data solutions to the global oil and gas industry, including our high resolution RG-3D Reservoir Grade™ ("RG3D") seismic solutions. Our seismic data solutions consist primarily of seismic data acquisition, microseismic monitoring, data processing and interpretation services. Through these services, we deliver data that enable the creation of high resolution images of the earth's subsurface and reveal complex structural and stratigraphic details. These images are used primarily by oil and gas companies to identify geologic structures favorable to the accumulation of hydrocarbons, to reduce risk associated with oil and gas exploration, to optimize well completion techniques and to monitor changes in hydrocarbon reservoirs. We integrate seismic survey design, data acquisition, processing and interpretation to deliver enhanced services to our clients. In addition, we own and market a growing seismic data library and license this data to clients on a non-exclusive basis.

We provide seismic data acquisition for land, transition zone and shallow marine areas, including challenging environments such as marshes, forests, jungles, arctic climates, mountains and deserts worldwide. Our management team has significant operational experience in most of the major U.S. shale plays, including the Haynesville, Barnett, Bakken, Fayetteville, Eagle Ford and Woodford, where we believe our high resolution RG3D seismic solutions are particularly well-suited.

Our seismic solutions are used by many of the world's largest and most technically advanced oil and gas exploration and production companies, including national oil companies ("NOCs") such as Oil and Natural Gas Corporation Limited ("ONGC") and Ecopetrol S.A. ("Ecopetrol"), major integrated oil and gas companies ("IOCs") such as BP p.l.c. ("BP"), ConocoPhillips Company ("ConocoPhillips") and Exxon Mobil Corporation ("ExxonMobil"), and independent oil and gas exploration and production companies such as Anadarko Petroleum Corporation ("Anadarko"), Apache Corporation, and Chesapeake Energy Corporation ("Chesapeake").

We currently own approximately 162,000 recording channels. Our recording channels and systems are interoperable providing operational scalability and efficiency, enabling us to execute on large and technologically complex projects.

We primarily generate revenues by providing Proprietary Services and Multi-client Services to our clients. Our Proprietary Services generate revenues by conducting geophysical surveys for our clients on a contractual basis where our clients generally acquire all rights to the seismic data obtained through such survey. We also generate revenues by providing microseismic monitoring, data processing and interpretation services. Our Multi-client Services generate revenues by selling licenses, on a non-exclusive basis, to data we own as a part of our seismic data library.

Revenues. We recorded revenues of $85.3 million for the three months ended June 30, 2011 compared to $40.1 million for the same period ended in 2010, an increase of $45.2, or 113%.

We recorded revenues from Proprietary Services of $46.4 million for the three months ended June 30, 2011, compared to $16.4 million for the same period in 2010, an increase of $30.0 million, or 183%. Latin America represented $36.5 million of that revenue, an increase of $27.9 million from the corresponding period in 2010. This growth was driven by additional program activity in Colombia and Brazil.  

Multi-client Services generated revenues of $38.9 million for the three months ended June 30, 2011 compared to $23.7 million for the same period of 2010, an increase of $15.2 million, or 64%.  The $38.9 million in Multi-client Services revenues included $7.2 million of late sale revenues and $31.6 million of pre-commitment revenues. This compared to $0.5 million in late sales revenues and $22.9 million of pre-commitment revenues during the same period of 2010.  Late sales revenues for the quarter were primarily driven by licenses to data sets in the Eagle-Ford, Bakken and Haynesville shale plays.

Operating expenses. Operating expenses, excluding depreciation and amortization increased by $17.4 million to $28.5 million for the three months ended June 30, 2011, an increase of 157%.  The primary increases to cost were compensation and benefits up by $4.7 million, subcontractor cost up by $7.0 million, reimbursable cost up by $1.3 million and material and supplies up by $1.9 million from the ramp up in costs on new projects in our International areas for the three months ended June 30, 2011 versus the same period in 2010.  These increases to cost were in line with the increases in revenues from our Proprietary Services.

Selling, General and Administrative Expenses. SG&A, excluding depreciation and amortization, decreased by $0.8 million, or 7%, to $10.6 million for the three months ended June 30, 2011.  The bad debt expense for the three months ended June 30, 2011 was nil, compared to $3.0 million in the same period of 2010.  This decrease in SG&A cost of $3.0 million was offset by the increased cost for the quarter ended June 30, 2011 related to our expanded sales and marketing staff, increased accounting and administrative costs associated with being a publicly traded company, and increases in our stock based compensation.

Depreciation and Amortization Expenses.  Total net depreciation and amortization expense increased by $11.8 million, or 54%, to $33.8 million for the three months ended June 30, 2011.  The Multi-client Services amortization expense was $26.4 million for the three months ended June 30, 2011, representing a 68% effective amortization rate for the period.  Gross depreciation expense for the quarter ended June 30, 2011 was $11.4 million, of which, $4.5 million was capitalized in connection with our Multi-client Services investments resulting in a net depreciation expense of $6.9 million.  Some of our older equipment is becoming fully depreciated and capital investments have been less than our historical average.

The following table summarizes our depreciation and amortization for the three month period ended (amounts in millions):

	Three Month Period Ended

Multi-client amortization expense		26.4			14.2
Total net depreciation & amortization expense	$	33.8		$	22.0
Average Multi-client amortization rate for the period		68	%		60	%

Interest Expense, Net. Interest expense, net, increased by $0.9 million, or 17%, to $6.3 million for the three months ended June 30, 2011, compared to $5.4 million for the same quarter of 2010.  The increases to interest expense relates to our borrowing costs from the issuance of $200 million, 10.5% senior notes and from our borrowings against the revolving line of credit.

Other Income (Expense), Net. Other income (expense), net, was a gain of $0.9 million for the three months ended June 30, 2011 compared to a loss of $6.0 million in the same quarter of 2010, a $6.9 million increase in income. We recorded a foreign exchange gain in the second quarter of 2011 for $0.9 million compared to a gain of $0.1 million in the same period of 2010, resulting in an overall increase to income for $0.8 million. During the three months ended June 30, 2010, we recorded a loss on the extinguishment of our prior debt for $6.0 million, compared to nil in the same period of 2011.

Income Tax Expense (Benefit). Our income tax expense for the three months ended June 30, 2011 was $1.9 million compared to a benefit of $10.2 million in the same period of 2010. The effective income tax rate for the three months ended June 30, 2011 and 2010 was adjusted to reflect the effective tax rate of 59% and 42%, respectively for the six months ended June 30, 2011 and 2010. The Company’s effective income tax rate in 2011 and 2010 differs from the federal statutory rate primarily due to state income taxes, non-deductible expenses, tax rate differential from US operations, and valuation allowances in non-US jurisdictions.

Operating expenses, excluding depreciation and amortization decreased by $0.7 million to $45.8 million for the six months ended June 30, 2011, a decrease of 2%.  The increases for the six months ended June 30, 2011 are primarily related to the start-up cost associated with new projects in our International areas.

Selling, General and Administrative Expenses. SG&A, excluding depreciation and amortization, increased by $1.5 million, or 8%, to $20.8 million for the six months ended June 30, 2011.  The SG&A cost increases relate to our expanded sales and marketing staff, increased accounting and administrative costs, associated with being a publicly traded company, and increases in our stock based compensation for the six month ended June 30, 2011.  This was slightly offset from bad debt expense of $3.0 million recorded in the same period of 2010 versus nil in 2011.

Depreciation and Amortization Expenses.  Total net depreciation and amortization expense increased by $27.4 million, or 68%, to $67.6 million for the six months ended June 30, 2011.  The Multi-client Services amortization expense was $51.9 million for the six months ended June 30, 2011, representing a 68% effective amortization rate compared to a 58% rate during the same period of 2010.  Gross depreciation expense for the six months ended June 30, 2011 was $24.0 million, of which, $9.2 million was capitalized in connection with our Multi-client Services investments resulting in a net depreciation expense of $14.8 million.  Some of our older equipment is becoming fully depreciated and capital investments have been less than our historical average.

The following table summarizes our depreciation and amortization for the six month period ended (amounts in millions):

	Six Month Period Ended

Gross depreciation expense	$	24.0		$	29.0

Net depreciation expense	$	14.8		$	17.0
Amortization of intangibles expense		0.9			0.3
Multi-client amortization expense		51.9			22.9
Total net depreciation & amortization expense	$	67.6		$	40.2
Average Multi-client amortization rate for the period		68	%		58	%

Interest Expense, Net. Interest expense, net, increased by $2.1 million, or 21%, to $12.1 million for the six months ended June 30, 2011, compared to $10.0 million for the same quarter of 2010.  The increases to interest expense relates to our borrowing costs from the issuance of $200 million, 10.5% senior notes and from our borrowings against the revolving line of credit.

Other Income (Expense), Net. Other income (expense), net, was a gain of $1.7 million for the six months ended June 30, 2011 compared to a loss of $5.9 million in the same quarter of 2010, a $7.6 million increase in income. We recorded a foreign exchange gain for the six months ended June 30, 2011 for $1.7 million, compared to a loss of $0.2 million during the same period of 2010, resulting in an overall increase to income for $1.9 million. During the six months ended June 30, 2010, we recorded a loss on the extinguishment of our prior debt for $6.0 million, compared to nil in the same period of 2011.

Income Tax Expense (Benefit). Our income tax expense for the six months ended June 30, 2011 was $5.0 million compared to a benefit of $13.8 million in the same period of 2010. The effective income tax rate for the six months ended June 30, 2011 and 2010 was approximately 59% and 42%, respectively. The Company’s effective income tax rate in 2011 and 2010 differs from the federal statutory rate primarily due to state income taxes, non-deductible expenses, tax rate differential from US operations, and valuation allowances in non-US jurisdictions.

31

EBITDA. We define EBITDA as net income before interest, taxes, depreciation and amortization. EBITDA is not a measure of financial performance derived in accordance with Generally Accepted Accounting Principles (GAAP) and should not be considered in isolation or as an alternative to net income as an indication of operating performance. The table below presents a reconciliation of EBITDA to net income (loss):

(1) EBIT, EBITDA, EBIT per share and EBITDA per share (as defined in the calculations above) are non GAAP measurements. Management uses EBIT and EBITDA because it believes that such measurements are widely accepted financial indicators used by investors and analyst to analyze and compare companies on the basis of operating performance.

(2) Excludes gain (loss) of sale of assets and includes amortization of intangibles.

(3) Calculated using diluted weighed average shares oustanding.

Our management believes EBITDA is useful to an investor in evaluating our operating performance because this measure is widely used by investors in the energy industry to measure a company’s operating performance without regard to items excluded from the calculation of such term, which can vary substantially from company to company depending upon, among other factors, accounting methods, book value of assets, capital structure and the method by which assets were acquired. We believe EBITDA helps investors more meaningfully evaluate and compare the results of our operations from period to period by removing the effect of our capital structure and asset base from our operating structure. EBITDA is also used as a supplemental financial measure by our management in presentations to our board of directors, as a basis for strategic planning and forecasting, and as a component for setting incentive compensation.

Liquidity and Capital Resources

Our primary sources of liquidity are cash generated by the Proprietary Services and Multi-client Services we provide to our clients, debt and equity offerings, our revolving credit facility, and equipment financings such as capital leases. Our primary uses of capital include the acquisition of seismic data recording equipment, seismic vehicles and vessels, other equipment needed to outfit new crews and to enhance the capabilities of and maintain existing crews’ energy sources, and investments in Multi-client Services data for our library. We also use capital to fund the working capital required to launch new crews and operate existing crews.  Our cash position, consistent with our revenues, depends to a large extent on the level of demand for our services. Historically, we have supplemented cash from operations with borrowings under our Revolving Credit Facility periodically from time to time as the need arises.

As of June 30, 2011, we had available liquidity as follows (amounts in millions):

	Six Month Period Ended

Available cash	$	13.2
Undrawn borrowing capacity under Revolving Credit Facility		21.5
Net available liquidity	$	34.7

The following table summarizes the net cash provided by (used in) operating, investing and financing activities for the six months ended June 30, 2011 and 2010 (amounts in millions):

Investing activities		(108.8	)		(67.6	)
Financing activities		34.5			91.3

Operating Activities. Net cash provided by operating activities was $59.2 million for the six months ended June 30, 2011 compared to $53.3 million for the same period ended 2010, an increase of $5.9 million. The primary changes were in net income which increased by $22.7 million, depreciation and amortization increase of $24.5 million, and a deferred revenue increase of $6.6 million, and were offset from the change in accounts receivable net, a decrease of $49.6 million.

Investing Activities. Net cash used in investing activities was $108.8 million for the six months ended June 30, 2011 compared to $67.6 million for the same period ended 2010, an increase of $41.2 million. The increase was primarily the result of increased investment in our Multi-client Services library.  The following table sets forth our investment in our Multi-client Services library for the period indicated (amounts in millions):

Multi-client net book value	$	207.0	$	92.7

(1)   Represents capitalized cost of the equipment, owned or leased, and utilized in connection with Multi-client Services.

Financing Activities. Net cash provided by financing activities was $34.5 million in the six months ended June 30, 2011 compared to $91.3 million for the same period in 2010, a decrease of $56.8 million.  The decrease represents the impact of the Company’s Initial Public Offering  and Senior Notes offering during the period June 30, 2010 , offset by borrowing under our Revolving Credit Facility for the period June 30, 2011.

Capital Resources  On April 30, 2010, we completed the closing of a new revolving credit facility under the terms of a Credit Agreement (the “Revolving Credit Facility”) with Bank of America, N.A., as administrative agent for each lender party to the Revolving Credit Facility.  Our Revolving Credit Facility provides for borrowings of up to $50.0 million. The loans under our Revolving Credit Facility bear interest at a rate equal to LIBOR plus the Applicable Rate or the Base Rate plus the Applicable Rate. The Base Rate is defined as the higher of (x) the prime rate and (y) the Federal Funds rate plus 0.50%. The Applicable Rate is defined as a percentage determined in accordance with a pricing grid based upon our leverage ratio, that will decline from LIBOR plus 4.00% or the prime rate plus 3.00% to a minimum rate equal to LIBOR plus 3.50% or the prime rate plus 2.50%. We are able to prepay borrowings under our Revolving Credit Facility at any time without penalty or premium, subject to reimbursement of the lenders’ breakage and redeployment costs in the case of prepayment of LIBOR borrowings. We also will pay a commitment fee of 0.75% per annum on the actual daily unused portions of the Revolving Credit Facility. On June 9, 2011, we amended the Revolving Credit Facility to provide for borrowings of up to $70.0 million under substantially similar terms.

Capital Expenditures. Capital expenditures for the six months ended June 30, 2011 were $126.9 million consisting of purchases of property and equipment of $13.9 million and investments in our Multi-client Services library of $113.0 million.

Contractual Obligations

The following table summarizes the payments due in specific periods related to our contractual obligations as of June 30, 2011 (amounts in millions):

	Total		Within 1 Year		1-3 Years		3-5 Years		After 5 Years

	$	262.9	$	10.2	$	52.2	$	0.5	$	200.0

Off Balance Sheet Arrangements

We do not currently have any off balance sheet arrangements.

Backlog

The Company’s Backlog as of June 30, 2011 was approximately $260 million ($152 million Multi-client Services pre-commitments; $108 million Proprietary Services) compared to $179 million as of June 30, 2010. Backlog as of March 31, 2011 was approximately $278 million.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

The primary sources of market risk are the volatility of oil and gas prices and the concentration of our clients in the oil and gas industry. The volatility of oil and gas prices may have a positive or negative effect on demand and pricing for our services. The concentration of substantially all of our clients in the oil and gas industry may have a positive or negative effect on our exposure to credit risk since all of our clients are similarly affected by changes in industry and economic conditions. We regularly maintain deposits in our bank accounts in excess of the $250,000 guaranteed by the Federal Deposit Insurance Corporation. We are subject to market risk exposure related to changes in interest rates on our outstanding floating rate debt. Borrowings under our Revolving Credit Facility bear floating-rate interest, at our option, based on LIBOR or the prime rate. We do not enter into interest rate hedges or other derivatives for speculative purposes.

Financial instruments, which potentially subject us to concentration of credit risk, consist primarily of unsecured trade receivables. In the normal course of business, we provide credit terms to our clients. Accordingly, we perform ongoing credit evaluations of our clients and maintain allowances for possible losses.

We conduct business in many foreign countries. We are subject to foreign exchange risks because our contracts may, from time-to-time, be denominated in currencies other than the U.S. dollar while a significant portion of our operating expenses and income taxes accrue in other currencies. Movements in the exchange rates between the U.S. dollar and other currencies may adversely affect our financial results. Historically, we have not attempted to hedge foreign exchange risk. For the six months ended June 30, 2011, approximately 40% of our revenues were recorded in foreign currencies, and we recorded net foreign exchange gain of $1.7 million, or 1% of revenues. We attempt to match our foreign currency revenues and expenses in order to balance our net position of receivables and payables in foreign currency. Nevertheless, during the past three years, foreign-denominated revenues have exceeded foreign-denominated payables primarily as a result of contract terms required by our national oil company clients. Our management believes that this will continue to be the case in the future.

Item 4. Controls and Procedures

Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we have performed an evaluation of the design, operation and effectiveness of the Company disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) as of June 30, 2011.  Based on that evaluation, the Company’s principal executive and principal financial officers have concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2011.

There were no changes in the Company’s internal control over financial reporting that occurred during the Company’s last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II.  OTHER INFORMATION

Item 1.  Legal Proceedings

Income Tax Disclosure [Text Block]

NOTE 6 - INCOME TAXES

The Company provides for income taxes during interim periods based on an estimate of the effective tax rate for the year.  Discrete items and changes in the estimate of the annual effective tax rate are recorded in the period in which they occur.

The Company assesses the likelihood that deferred tax assets will be recovered from the existing deferred tax liabilities or future taxable income in each jurisdiction.  To the extent the Company believes that recovery is not likely, it establishes a valuation allowance.  The Company has recorded valuation allowances in several non-US jurisdictions for its net deferred tax assets since management believes it is more likely than not that these assets will not be realized because the future taxable income necessary to utilize these losses cannot be established, projected, or the Company no longer has operations in these jurisdictions.

The effective income tax rate for the six months ended June 30, 2011 and 2010 was 58.7% and 41.8%, respectively.

The Company’s effective income tax rate in 2011 and 2010 differs from the federal statutory rate primarily due to state income taxes, non-deductible expenses, tax rate differential from US operations, and valuation allowances in non-US jurisdictions.

Note 9 - Fair Values Of Financial Instruments

6 Months Ended

Jun. 30, 2011

Fair Value Disclosures [Text Block]

NOTE 9 – FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company follows current guidance as it relates to financial assets and financial liabilities, which defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles and expands disclosures about fair value measurements.  The provisions of this standard apply to other accounting pronouncements that require or permit fair value measurements.

This guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.   Hierarchical levels, as defined in this guidance and directly related to the amount of subjectivity associated with the inputs to fair valuations of these assets and liabilities are as follows:

Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 – Inputs that are both significant to the fair value measurement and unobservable.

The reported fair values for financial instruments that use Level 2 and Level 3 inputs to determine fair value are based on a variety of factors and assumptions. Accordingly, certain fair values may not represent actual values of the financial instruments that could have been realized as of June 30, 2011 or that will be realized in the future and do not include expenses that could be incurred in an actual sale or settlement.

In the normal course of operations, the Company is exposed to market risks arising from adverse changes in interest rates.  Market risk is defined for these purposes as the potential for change in the fair value of debt instruments resulting from an adverse movement in interest rates.

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and current debt approximate their fair value due to the short maturity of those instruments, and therefore, have been excluded from the table below.  The fair value of the Notes is determined by multiplying the principal amount by the market price.  The following table sets forth the fair value of the Company’s financial assets and liabilities as of June 30, 2011 and December 31, 2010:

	June 30, 2011				December 31, 2010
	(unaudited)
	Carrying		Fair		Carrying		Fair
	Amount		Value		Amount		Value
Long-term debt	$	194,737,270	$	215,000,000	$	194,418,242	$	198,250,000

The Company is not a party to any hedge arrangements, commodity swap agreements or other derivative financial instruments.

The Company utilizes foreign subsidiaries and branches to conduct operations outside of the United States. These operations expose the Company to market risks from changes in foreign exchange rates.

Long-term Debt [Text Block]

NOTE 7 - LONG-TERM DEBT

Senior Notes: On April 22, 2010, the Company entered into a Purchase Agreement (the “Purchase Agreement”) with Barclays Capital Inc., Credit Suisse Securities (USA) LLC and Banc of America Securities LLC, as representatives of the initial purchasers (the “Initial Purchasers”), relating to the offer and sale by the Company of $200 million aggregate principal amount of its 10.5% senior notes due 2017 (the “Notes”).  The Company’s net proceeds from the offering were approximately $188.1 million after deducting the Initial Purchasers’ discounts, offering expenses and original issue discount. The issuance of the Notes occurred on April 27, 2010. The Notes were offered and sold to the Initial Purchasers and resold only to qualified institutional buyers in compliance with the exemption from registration provided by Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and in offshore transactions in reliance on Regulation S under the Securities Act.

The Notes are a general unsecured, senior obligation of the Company. The Notes are unconditionally guaranteed as to principal, premium, if any, and interest by the Company’s domestic subsidiaries (the “Guarantors”) on a senior unsecured basis. (See Note 15)

The Company used the proceeds from the offering and sale of the Notes to repay outstanding indebtedness and plans to use the remaining proceeds for anticipated capital expenditures and for general working capital purposes.

On April 27, 2010, in connection with the offering of the Notes, the Company entered into (i) an Indenture with The Bank of New York Mellon Trust Company, N.A., (the “Trustee”), and (ii) a Registration Rights Agreement with the Initial Purchasers. The following is a brief summary of the material terms and conditions of the Indenture and the Registration Rights Agreement.

The Company and the Guarantors entered into an Indenture with the Trustee, pursuant to which the Company issued the Notes at a price equal to 97.009% of their face value.

Interest — The Notes will bear interest from April 27, 2010 at a rate of 10.5% per annum. The Company will pay interest on the Notes semi-annually, in arrears, on May 1 and November 1 of each year, beginning November 1, 2010.

Principal and Maturity — The Notes were issued with a $200 million aggregate principal amount and will mature on May 1, 2017.

Optional Redemption by the Company — At any time prior to May 1, 2013, the Company may redeem up to 35% of the aggregate principal amount of the Notes with the net cash proceeds of certain equity offerings at a redemption price of 110.500% of the aggregate principal amount of the Notes redeemed if at least 65% of the aggregate principal amount of the Notes remains outstanding immediately after such redemption and the redemption occurs within 90 days of the closing date of such equity offering. On or after May 1, 2014, the Company may redeem the Notes at the following percentages of the original principal amount: (i) 105.250% from May 1, 2014 to April 30, 2015; (ii) 102.625% from May 1, 2015 to April 30, 2016; and (iii) 100% from May 1, 2016 and thereafter.

Repurchase Obligations by the Company — If there is a change of control of the Company (as defined in the Indenture), each holder of the Notes may require the Company to purchase their Notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase.

Events of Default — The Indenture also contains events of default including, but not limited to, the following: (i) nonpayment; (ii) defaults in certain other indebtedness of the Company or the Guarantors; and (iii) the failure of the Company or the Guarantors to comply with their respective covenants in the event of a mandatory redemption, optional redemption, option to repurchase, or a merger, consolidation or sale of assets. Upon an event of default, the holders of the Notes or the Trustee may declare the Notes due and immediately payable. As of June 30, 2011, the Company is in compliance with all respective covenants.

Debt Issuance Costs: The costs related to the issuance of debt are capitalized and amortized to interest expense using the effective interest method over the maturity period of the related debt. Accumulated amortization is $712,093 and $396,248 at June 30, 2011 and December 31, 2010, respectively.

Bank of America Revolving Credit Facility: On April 30, 2010, the Company entered into a revolving credit facility under the terms of a Credit Agreement (the “Revolving Credit Facility”) with Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer, and each lender from time to time party thereto. The Revolving Credit Facility provided for borrowings of up to $50.0 million. The loans under the Revolving Credit Facility bear interest at a rate equal to LIBOR plus the Applicable Rate or the Base Rate plus the Applicable Rate. The Base Rate is defined as the higher of (x) the prime rate and (y) the Federal Funds rate plus 0.50%. The Applicable Rate is defined as a percentage determined in accordance with a pricing grid based upon the Company’s leverage ratio, that will decline from LIBOR plus 4.00% or the prime rate plus 3.00% to a minimum rate equal to LIBOR plus 3.50% or the prime rate plus 2.50%. The Company is able to prepay borrowings under the Revolving Credit Facility at any time without penalty or premium, subject to reimbursement of the lenders’ breakage and redeployment costs in the case of prepayment of LIBOR borrowings. The Company also will pay a commitment fee of 0.75% per annum on the actual daily unused portions of the Revolving Credit Facility.

The Company’s Revolving Credit Facility is secured by a first priority lien on substantially all of the Company’s assets, the assets of the Company’s non-foreign subsidiaries, the stock of the Company’s non-foreign subsidiaries and 66% of the stock of certain of the Company’s foreign subsidiaries. In addition, the Company’s non-foreign subsidiaries will guarantee the Company’s obligations under the Revolving Credit Facility.

The terms of the Revolving Credit Facility will limit the Company’s ability and the ability of certain of the Company’s subsidiaries to, among other things: incur or guarantee additional indebtedness; grant additional liens on the Company’s assets; make certain investments or certain acquisitions of substantially all or a portion of another entity’s business or assets; merge with another entity or dispose of the Company’s assets; pay dividends; enter into transactions with affiliates; engage in other lines of business and repurchase stock.

Additionally, the Revolving Credit Facility requires that the Company maintain certain ratios of total senior, secured debt to consolidated EBITDA (as defined therein), and of consolidated EBITDA to consolidated interest. The Revolving Credit Facility includes customary provisions with respect to events of default. Upon the occurrence and continuation of an event of default under the Revolving Credit Facility, the lenders will be able to, among other things, terminate their revolving loan commitments, accelerate the repayment of the loans outstanding and declare the same to be immediately due and payable. As of June 30, 2011, the Company is in compliance with all respective covenants.

On June 9, 2011, the Company amended the Revolving Credit Facility to provide for borrowings of up to $70.0 million under substantially similar terms.

In connection with the closing of the Company’s initial public offering and the sale of $200 million of the Company’s 10.5% senior notes due 2017 on April 27, 2010, the Company repaid all outstanding borrowings under the First Lien Credit Agreement, the Second Lien Credit Agreement, and the Construction Loan Agreement. These repayments resulted in the termination of each of these borrowing arrangements.

Note 10 - Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]

NOTE 10 - STOCK-BASED COMPENSATION

The Company follows the current guidance for share-based payments which requires all stock-based payments, including stock options, to be recognized as an operating expense over the vesting period, based on their grant date fair values.

In July 2006, the Company’s board of directors and stockholders adopted the Global Geophysical Services, Inc. 2006 Incentive Compensation Plan (the “2006 Incentive Plan”).  The 2006 Incentive Plan provides for a variety of  incentive awards, including nonstatutory stock options, incentive stock options within the meaning of Section 422 of the Internal Revenue Code, or (the “Code”), stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based awards, and other stock-based awards.  A total of 9,203,058 shares of common stock are reserved for issuance under the 2006 Incentive Plan.  As of June 30, 2011, a total of 4,830,400 options have been granted and 2,068,200 have been forfeited.

Incentive Stock Options:  The Company estimates the fair value of each stock option on the date of grant using the Black-Scholes-Merton valuation model.  The volatility is based on expected volatility over the expected life of eighty-four months.  As the Company has not historically declared dividends, the dividend yield used in the calculation is zero. Actual value realized, if any, is dependent on the future performance of the Company’s common stock and overall stock market conditions.  There is no assurance the value realized by an optionee will be at or near the value estimated by the Black-Scholes-Merton model.

The following assumptions were used:

	Six Months Ended
	June 30,
	2011			2010
Risk-free interest rates		2.68	%		3.05	%
Expected lives (in years)		7.00			7.00
Expected dividend yield		0.00	%		0.00	%
Expected volatility		59.08	%		59.09	%

The computation of expected volatility during the three and six months ended June 30, 2011 and 2010 was based on the historical volatility. Historical volatility was calculated from historical data for the time approximately equal to the expected term of the option award starting from the grant date. The risk-free interest rate assumption is based upon the U.S. Treasury yield curve in effect at the time of grant for the period corresponding with the expected life of the option.

A summary of the activity of the Company’s stock option plan for the six months ended June 30, 2011 is presented below:

						Weighted		Weighted

	Average		Number of			Remaining		Optioned

Stock Warrants:  At June 30, 2011, the Company has outstanding warrants which entitle the holders to purchase an aggregate of 390,000 shares of common stock of the Company at an exercise price of $4.25 per share. These warrants were subsequently exercised in July 2011,

Restricted Stock:  To encourage retention and performance, the Company granted certain employees and consultants restricted shares of common stock with a fair value per share determined in accordance with conventional valuation techniques, including but not limited to, arm’s length transactions, net book value or multiples of comparable company earnings before interest, taxes, depreciation and amortization, as applicable.

	Number of			Weighted

Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block]

NOTE 14 – RECENTLY ISSUED ACCOUNTING STANDARDS

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04, “Fair Value Measurements (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS,” (“ASU 2011-04”). ASU 2011-04 changes the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements to ensure consistency between U.S. GAAP and International Financial Reporting Standards (“IFRS”). ASU 2011-04 also expands the disclosures for fair value measurements that are estimated using significant unobservable (Level 3) inputs. This new guidance is to be applied prospectively. ASU 2011-04 will be effective for interim and annual periods beginning after Dec. 15, 2011, with early adoption permitted. We believe that the adoption of this standard will not materially expand our consolidated financial statement footnote disclosures.
