Organization and Summary of Significant Accounting Policies [Abstract]

Organization and Summary of Significant Accounting Policies

1. Organization and Summary of Significant Accounting Policies

Organization—Mitcham Industries, Inc., a Texas corporation (the “Company”), was incorporated in 1987. The Company, through its wholly owned Canadian subsidiary, Mitcham Canada, ULC (“MCL”), its wholly owned Russian subsidiary, Mitcham Seismic Eurasia LLC (“MSE”), its wholly owned Hungarian subsidiary, Mitcham Europe Ltd. (“MEL”), its wholly owned Singaporean subsidiary Mitcham Marine Leasing Pte. Ltd. (“MML”), and its branch operations in Colombia and Peru, provides full-service equipment leasing, sales and service to the seismic industry worldwide. The Company, through its wholly owned Australian subsidiary, Seismic Asia Pacific Pty Ltd. (“SAP”), provides seismic, oceanographic and hydrographic leasing and sales worldwide, primarily in Southeast Asia and Australia. The Company, through its wholly owned subsidiary, Seamap International Holdings Pte, Ltd. (“Seamap”), designs, manufactures and sells a broad range of proprietary products for the seismic, hydrographic and offshore industries with product sales and support facilities based in Singapore and the United Kingdom. All intercompany transactions and balances have been eliminated in consolidation.

Revenue Recognition of Leasing Arrangements—The Company leases various types of seismic equipment to seismic data acquisition companies. All leases at January 31, 2013 and 2012 are for one year or less. Lease revenue is recognized ratably over the term of the lease. The Company does not enter into leases with embedded maintenance obligations. The standard lease provides that the lessee is responsible for maintenance and repairs to the equipment, excluding normal wear and tear. The Company provides technical advice to its customers without additional compensation as part of its customer service practices. Repairs or maintenance performed by the Company is charged to the lessee, generally on a time and materials basis.

Revenue Recognition of Equipment Sales—Revenues and cost of goods sold from the sale of equipment is recognized upon acceptance of terms and when delivery has occurred, unless there is a question as to its collectability. In cases where the equipment sold is manufactured by others, the Company reports revenues at gross amounts billed to customers because the Company (a) is the obligor in the sales arrangement; (b) has full latitude in pricing the product for sale; (c) has general inventory risk should there be a problem with the equipment being sold to the customer or if the customer does not complete payment for the items purchased; (d) has discretion in supplier selection if the equipment ordered is not unique to one manufacturer; and (e) assumes credit risk for the equipment sold to its customers.

Revenue Recognition of Long-term Projects—From time to time, SAP enters into contracts whereby it assembles and sells certain marine equipment, primarily to governmental entities. Performance under these contracts generally occurs over a period of several months. Revenue and costs related to these contracts are accounted for under the percentage of completion method, based on estimated physical completion.

Revenue Recognition of Service Agreements—Seamap provides on-going support services pursuant to contracts that generally have a term of 12 months. The Company recognizes revenue from these contracts over the term of the contract. In some cases, the Company will provide support services on a time and material basis. Revenue from these arrangements is recognized as the services are provided. For certain new systems that Seamap sells, the Company provides support services for up to 12 months at no additional charge. Any amounts attributable to these support obligations are immaterial.

Contracts receivable—In connection with the sale of seismic equipment, the Company will, from time to time, accept a contract receivable as partial consideration. These contracts bear interest at a market rate and generally have terms of less than two years and are collateralized by a security interest in the equipment sold. Interest income on contracts receivable is recognized as earned, unless there is a question as to collectability in which case it is recognized when received.

Allowance for doubtful accounts—Trade receivables are uncollateralized customer obligations due under normal trade terms. The carrying amount of trade receivables and contracts receivable is reduced by a valuation allowance that reflects management’s estimate of the amounts that will not be collected, based on the age of the receivable, payment history of the customer, general financial condition of the customer and any financial or operational leverage the Company may have in a particular situation. Amounts are written-off when collection is deemed unlikely. Past due amounts are determined based on contractual terms.

Cash and Cash Equivalents—The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents.

Short-term Investments—The Company considers all highly liquid investments with an original maturity greater than three months, but less than twelve months, to be short-term investments.

Inventories—Inventories are stated at the lower of average cost (which approximates first-in, first-out) or market. An allowance for obsolescence is maintained to reduce the carrying value of any materials or parts that may become obsolete. Inventories are periodically monitored to ensure that the allowance for obsolescence covers any obsolete items.

Seismic Equipment Lease Pool—Seismic equipment held for lease consists primarily of recording channels and peripheral equipment and is carried at cost, net of accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives of the equipment, which are five to seven years for channel boxes and two to ten years for other peripheral equipment. As this equipment is subject to technological obsolescence and wear and tear, no salvage value is assigned to it. The Company continues to lease seismic equipment after it has been fully depreciated if it remains in acceptable condition and meets acceptable technical standards. This fully depreciated equipment remains in fixed assets on the Company’s books. The Company removes from its books the cost and accumulated depreciation of fully depreciated assets that are not expected to generate future revenues.

Property and Equipment—Property and equipment is carried at cost, net of accumulated depreciation. Depreciation is computed on the straight-line method over their related estimated useful lives. The estimated useful lives of equipment range from three to seven years. Buildings are depreciated over 30 years and property improvements are amortized over 10 years. Leasehold improvements are amortized over the shorter of the realized estimated useful life or the life of the respective leases. No salvage value is assigned to property and equipment.

Intangible Assets—Intangible assets are carried at cost, net of accumulated amortization. Amortization is computed on the straight-line method over the estimated life of the asset. Covenants-not-to-compete are amortized over a three-year period. Proprietary rights are amortized over a 12.5 to 15-year period.

Impairment—The Company’s long-lived assets are measured at the lower of carrying amount or fair value less cost to sell. The Company reviews its long-lived assets, including its amortizable intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In reviewing for impairment, the carrying value of such assets is compared to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. If such cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to reduce the carrying value of the long-lived asset to its estimated fair value. The determination of future cash flows as well as the estimated fair value of long-lived assets involves significant estimates on the part of management. The Company performs an impairment test on goodwill on an annual basis. No impairment charges related to long-lived assets or goodwill were recorded during the fiscal years ended January 31, 2013, 2012 or 2011.

Product Warranties—Seamap provides its customers warranties against defects in materials and workmanship generally for a period of three months after delivery of the product. The Company maintains an accrual for potential warranty costs based on historical warranty claims. For the fiscal years ended January 31, 2013, 2012 and 2011, warranty expense amounted to approximately $61,000, $3,000, and $70,000, respectively.

Income Taxes—The Company accounts for income taxes under the liability method, whereby the Company recognizes, on a current and long-term basis, deferred tax assets and liabilities which represent differences between the financial and income tax reporting bases of its assets and liabilities. Deferred tax assets and liabilities are determined based on temporary differences between income and expenses reported for financial reporting and tax reporting. The Company has assessed, using all available positive and negative evidence, the likelihood that the deferred tax assets will be recovered from future taxable income.

The weight given to the potential effect of negative and positive evidence is commensurate with the extent to which it can be objectively verified. The preponderance of negative or positive evidence supports a conclusion regarding the need for a valuation allowance for some portion of, or all of, the deferred tax asset. The more significant types of evidence considered include the following:

•

taxable income projections in future years;

•

whether the carry forward period is so brief that it would limit realization of tax benefits;

•

future sales and operating cost projections that will produce more than enough taxable income to realize the deferred tax asset based on existing sales prices and cost structures; and

•

earnings history exclusive of the loss that created the future deductible amount coupled with evidence indicating that the loss is an aberration rather than a continuing condition.

Use of Estimates—The preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company’s management to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes. Estimates are used for, but not limited to the allowance for doubtful accounts, lease pool valuations, valuation allowance on deferred tax assets, the evaluation of uncertain tax positions, estimated depreciable lives of fixed assets and intangible assets, impairment of fixed assets and intangible assets and the valuation of stock options. Future events and their effects cannot be perceived with certainty. Accordingly, these accounting estimates require the exercise of judgment. The accounting estimates used in the preparation of the consolidated financial statements will change as new events occur, as more experience is acquired, as additional information is obtained and as the Company’s operating environment changes. Actual results could differ from these estimates.

Substantial judgment is necessary in the determination of the appropriate levels for the Company’s allowance for doubtful accounts because of the extended payment terms the Company often offers to its customers and the limited financial wherewithal of certain of these customers. As a result, the Company’s allowance for doubtful accounts could change in the future, and such change could be material to the financial statements taken as a whole. The Company must also make substantial judgments regarding the valuation allowance on deferred tax assets.

Fair Value of Financial Instruments—The Company’s financial instruments consist of trade receivables, contracts receivable and accounts payable. Due to the short maturities of these financial instruments, the Company believes that their fair value approximates their carrying amounts.

Foreign Currency Translation—All balance sheet accounts of the Canadian, Australian, Singaporean, Hungarian, United Kingdom and Russian subsidiaries and our branch operations in Colombia and Peru have been translated at the current exchange rate as of the end of the accounting period. Statements of operations items have been translated at average currency exchange rates. The resulting translation adjustment is recorded as a separate component of comprehensive income within shareholders’ equity.

Stock-Based Compensation—Stock –Based compensation expense is recorded based on the grant date fair value of share-based awards. Determining the grant date fair value requires management to make estimates regarding the variables used in the calculation of the grant date fair value. Those variables are the future volatility of our common stock price, the length of time an optionee will hold their options until exercising them (the “expected term”), and the number of options or shares that will be forfeited before they are exercised (the “forfeiture rate”). We utilize various mathematical models in calculating the variables. Share-based compensation expense could be different if we used different models to calculate the variables.

Earnings Per Share—Net income per basic common share is computed using the weighted average number of common shares outstanding during the period. Net income per diluted common share is computed using the weighted average number of common shares and potential common shares outstanding during the period. Potential common shares result from the assumed exercise of outstanding common stock options having a dilutive effect using the treasury stock method, from unvested shares of restricted stock using the treasury stock method and from outstanding common stock warrants. For the fiscal years ended January 31, 2013, 2012 and 2011, the following table sets forth the number of dilutive shares that may be issued pursuant to options, restricted stock and warrants outstanding used in the per share calculations.


	Years Ended January 31,

New Accounting Pronouncements [Abstract]

New Accounting Pronouncements

2. New Accounting Pronouncements

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 was effective during the fiscal year ended January 31, 2013 and is applied prospectively. The adoption of ASU 2011-04 did not have a material effect on the Company’s 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 was effective during the fiscal year ended January 31, 2013, though earlier adoption was permitted. The update was applied retrospectively upon adoption. The adoption did not have a material effect on the Company’s 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 January 31, 2012 in its year-end goodwill impairment analysis. The adoption of this standard did not have a material effect on the Company’s financial statements.

Acquisition [Abstract]

Acquisition

3. Acquisition

On March 1, 2010, MCL acquired all of the capital stock of Absolute Equipment Solutions, Inc. (“AES”) for a total purchase price of Cdn $4,194,000 (approximately U.S. $3,984,000). AES manufactured, sold and leased “heli-pickers” and associated equipment that is utilized in the deployment and retrieval of seismic equipment by helicopters. The Company made this acquisition to expand the type of equipment available to its customers and to expand the markets in which it operates. The consideration consisted of cash paid at closing in the amount of Cdn $2,200,000 (approximately U.S. $2,100,000), promissory notes in the amount of Cdn $1,500,000 (approximately U.S. $1,425,000), a post-closing working capital adjustment payment of Cdn $194,000 (approximately U.S. $184,000) and deferred cash payments in the amount of Cdn $300,000. The promissory notes bore interest at 6% annually, payable semi-annually. The principal amount of the notes was repayable in two equal installments on March 1, 2011 and 2012. The deferred cash payments will be made upon the expiration of certain indemnity periods. MCL may offset amounts due pursuant to the promissory notes or the deferred cash payment against indemnity claims due from the sellers. In addition, the sellers were entitled to additional cash payments of up to Cdn $750,000 should AES attain certain levels of revenues during the 24-month period following the acquisition, as specified in the agreement.

The Company hired an outside consulting firm, The BVA Group L.L.C. (“BVA”), to assess the fair value of the assets and liabilities acquired in the AES acquisition. The fair value of the contingent consideration was determined to be approximately Cdn $200,000. During the fiscal year ended January 31, 2012, the Company recorded a charge of approximately $400,000 in other expense to reflect the amount of the estimated contingent consideration payments in excess of the estimated fair value of the contingent consideration described above. There were no amounts recognized related to other contingencies. The fair value of the assets and liabilities acquired exceeded the total value of consideration paid, resulting in a bargain purchase.

The Company paid the sellers approximately $148,000 in April 2011 pursuant to the first stage of the contingent consideration provision of the agreement and in May 2012 approximately $450,000 pursuant to the second and final stage of this provision.

Upon the initial determination that the transaction had resulted in a bargain purchase, management and BVA reviewed the assets and liabilities acquired and the assumptions utilized in estimating their fair value. Certain revisions were made to these estimates, which resulted in a reduction in, but not the elimination of, the gain from bargain purchase. In this review, management noted that the information used in determining the fair value of the assets was the same information used to estimate the fair value of the contingent consideration portion of the purchase price. Further revisions to the estimates were not deemed to be appropriate.

Management then under took a review to determine what factors might contribute to a bargain purchase and if it were reasonable for a bargain purchase to occur. In this review, management noted that at the time the transaction was negotiated with the owners of AES, the oil services industry had recently experienced a decline and there was uncertainty as to the speed or depth of a recovery. Management believed that this situation was particularly difficult on small companies, such as AES, who had limited access to capital and liquidity. Furthermore, it appeared to management that the owners of AES were motivated to complete a transaction for personal financial reasons. Management also noted that there was a limited market for companies such as AES. Based upon all of these factors, management concluded that the occurrence of bargain purchase was reasonable. Accordingly, a gain of $1,304,000 was recorded as of the date of acquisition and no goodwill resulted from the transaction.

The following is a summary of the amounts recognized for assets acquired and liabilities assumed at the date of acquisition (in thousands):


Working capital	$	327
Seismic equipment lease pool		2,990
Deferred taxes		(1,086	)
Intangible assets		3,154

Revenue and net income for AES were $2,855,000 and $489,000, respectively, for the eleven months ended January 31, 2011. The operations of AES are included in our Equipment Leasing segment. Effective February 1, 2012, AES was merged into MCL.

In August 2012, the Company entered into an amended credit agreement with First Victoria Bank (the “Bank”) that provides for borrowings of up to $50,000,000 on a revolving basis through August 31, 2015 (the “Revolving Credit Facility”). The Company may, at its option, convert any or all balances outstanding under the Revolving Credit Facility into a series of term notes with monthly amortization over 48 months.

Amounts available for borrowing under the Revolving Credit Facility are determined by a borrowing base. The borrowing base is computed based upon certain outstanding accounts receivable, certain portions of the Company’s lease pool and certain lease pool assets that have been purchased with proceeds from the Revolving Credit Facility. The Revolving Credit Facility and any term loan are collateralized by essentially all of the Company’s domestic assets. Interest is payable monthly at the greater of the prime rate or 3.25%. As of January 31, 2013, the applicable rate was 3.25%. Up to $10,000,000 of available borrowings under the Revolving Credit Facility may be utilized to secure letters of credit. As of January 31, 2013, there were outstanding stand-by letters of credit totaling approximately $622,000. The Revolving Credit Facility contains certain financial covenants that require, among other things, for the Company to maintain a debt to shareholders’ equity ratio of no more than 0.7 to 1.0, maintain a current assets to current liabilities ratio of not less than 1.25 to 1.0; and have quarterly earnings before interest, taxes, depreciation and amortization (“EBITDA”) of not less than $2,000,000. The Revolving Credit Facility also provides that the Company may not incur or maintain indebtedness in excess of $10,000,000 without the prior written consent of the Bank, except for borrowings related to the Revolving Credit Facility. The Company may also guaranty up to $5,000,000 of subsidiary debt without the Bank’s prior consent. The Company was in compliance with each of these provisions as of and for the twelve months ended January 31, 2013. The Company’s average borrowings under the Revolving Credit Facility for the twelve months ended January 31, 2013 and 2012 were approximately $13,046,000 and $12,239,000, respectively.

In October 2010, the Company entered into a $3.6 million secured promissory note with a supplier in connection with the purchase of certain lease pool equipment. The note, which was repaid in March 2012, was repayable in 18 monthly installments, bore interest at 8% annually and was secured by the equipment purchased. The Company received the consent of the Bank for this transaction, as required by the terms of the revolving line of credit.

In March 2010, MCL entered into two promissory notes related to the purchase of AES. The notes bore interest at 6.0% per year with the first of two equal installments paid in March 2011 and the balance in March 2012.

From time to time, certain subsidiaries have entered into notes payable to finance the purchase of certain equipment, which are secured by the equipment purchased.

In the fiscal years ended January 31, 2013 and 2012, the tax deduction related to stock-based compensation awards exceeded the cumulative book expense related to these awards. The associated excess tax benefit amounting to approximately $420,000 and $778,000 was recognized as additional paid-in capital in the fiscal years ended January 31, 2013 and 2012, respectively. During the fiscal year ended January 31, 2010, certain stock based compensation agreements were settled or expired such that the book expense related to these agreements exceeded the tax deduction received by the Company. Accordingly, the deferred tax asset related to these items was reduced by approximately $346,000, which reduced additional paid-in capital.

At January 31, 2013, the Company had foreign withholding tax credit carry forwards of approximately $3,449,000, which amounts can be carried forward through at least 2020.

In July 2012, the Company reached a settlement with the Canadian Revenue Agency (“CRA”) and the Internal Revenue Service (“IRS”) regarding its request for competent authority assistance for matters arising from an audit of the Company’s Canadian income tax returns for the fiscal years ended January 31, 2004, 2005 and 2006. The issues involved related to intercompany repair charges, management fees and the deductibility of depreciation charges and whether those deductions should be taken in Canada or in the United States. Pursuant to the settlement agreement, adjustments will be made to the Company’s Canadian and United States income tax returns for the fiscal years ended January 31, 2004 through January 31, 2012. These changes are estimated to result in a net reduction to consolidated income tax expense of approximately $141,000, which is reflected in the Company’s benefit from income taxes for the fiscal year ended January 31, 2013.

As a result of the settlement, the Company has recognized the benefit of certain tax positions amounting to approximately $3,300,000 and has reversed previous estimates of potential penalties and interest amounting to approximately $1,900,000.

As of January 31, 2013 and 2012, the Company had unrecognized tax benefits amounting to approximately $376,000 and $5,435,000, respectively, attributable to uncertain tax positions. The Company recognizes interest and penalties related to income tax matters as a component of income tax expense. The unrecognized tax benefits attributable to uncertain tax positions include accrued interest and penalties of approximately $376,000 and $2,135,000 as of January 31, 2013 and January 31, 2012, respectively. Included in income tax expense for the fiscal years ended January 31, 2013, 2012 and 2011 are expenses of $93,000, $578,000 and $256,000, respectively, related to potential penalties and interest.

A reconciliation of the beginning and ending amounts of unrecognized tax benefits, excluding potential penalties and interest, is as follows:

The Company files U.S. federal income tax returns as well as separate returns for its foreign subsidiaries within their local jurisdictions. The Company’s U.S. federal tax returns are subject to examination by the IRS for fiscal years ended January 31, 2010 through 2013. However, the fiscal years ended January 31, 2004 through January 31, 2009 remain open as they relate to the implementation of competent authority settlement with the IRS. The Company’s tax returns may also be subject to examination by state and local revenue authorities for fiscal years ended January 31, 2008 through 2013.

The Company’s Canadian income tax returns are subject to examination by the Canadian tax authorities for fiscal years ended January 31, 2009 through 2013. However, the fiscal years ended January 31, 2004 through January 31, 2008 remain open as they relate to the implementation of the competent authority settlement agreement with the CRA.

The Company’s tax returns in other foreign jurisdictions are generally subject to examination for the fiscal years ended January 31, 2008 through January 31, 2013.

The total compensation expense related to stock-based awards granted under these plans during the fiscal years ended January 31, 2013, 2012 and 2011 was approximately $1,586,000, $1,331,000 and $1,099,000, respectively. The Company recognizes stock-based compensation costs net of a forfeiture rate for only those shares expected to vest over the requisite service period of the award. The Company estimates the forfeiture rate based on its historical experience regarding employee terminations and forfeitures.

The fair value of each option award is estimated as of the date of grant using a Black-Scholes-Merton option pricing formula. Expected volatility is based on historical volatility of the Company’s stock over a preceding period commensurate with the expected term of the option. The expected term is based upon historical exercise patterns. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Expected dividend yield was not considered in the option pricing formula since the Company does not pay dividends and has no plans to do so in the future. The weighted average grant-date fair value of options granted during the fiscal years ended January 31, 2013, 2012 and 2011 was $8.10, $6.44 and $2.75, respectively. The assumptions for the periods indicated are noted in the following table.

Weighted average Black-Scholes-Merton fair value assumptions


	Years Ended January 31,
	2013	2012	2011
Risk free interest rate	0.58 - 0.78%	1.52 -2.00%	1.82 - 1.97%
Expected life	3.28 - 6.60 yrs	2.85 - 4.89 yrs	2.4 - 4.4 yrs
Expected volatility	59 - 60%	54 - 55%	57 - 58%
Expected dividend yield	0.0%	0.0%	0.0%

Cash flows resulting from tax benefits attributable to tax deductions in excess of the compensation expense recognized for those options (excess tax benefits) are classified as financing in-flows and operating out-flows. The Company had excess tax expenses of approximately $420,000 and $778,000 during the fiscal years ended January 31, 2013 and 2012, respectively. The Company had an excess tax benefit of approximately $5,000 during the fiscal year ended January 31, 2011.

The Company has share-based awards outstanding under five different plans: the 1994 Stock Option Plan (“1994 Plan”), the 1998 Amended and Restated Stock Awards Plan (“1998 Plan”), the 2000 Stock Option Plan (“2000 Plan”), the Mitcham Industries, Inc. Stock Awards Plan (“2006 Plan”) and the 1994 Non-Employee Director Plan (“Director Plan”), (collectively, the “Plans”). Stock options granted and outstanding under each of the plans generally vest evenly over three years (except for the Director Plan, under which options generally vest after one year) and have a 10-year contractual term. The exercise price of a stock option generally is equal to the fair market value of the Company’s common stock on the option grant date. All Plans except for the 2006 Plan have been closed for future grants. All shares available but not granted under the 1998 Plan and the 2000 Plan as of the date of the approval of the 2006 Plan were transferred to the 2006 Plan. As of January 31, 2013, there were approximately 223,000 shares were available for grant under the 2006 Plan. The 2006 Plan provides for awards of nonqualified stock options, incentive stock options, restricted stock awards, restricted stock units and phantom stock. New shares are issued for restricted stock and upon the exercise of options.

Stock Based Compensation Activity

The following table presents a summary of the Company’s stock option activity for the fiscal year ended January 31, 2013:


	Number of Shares (in thousands)			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (in thousands)
Outstanding, January 31, 2012		1,413		$	9.60
Granted		172			18.21
Exercised		(158	)		2.10
Forfeited		—			—
Expired		—			—

Outstanding, January 31, 2013		1,427		$	11.37		5.23	$	6,192

Exercisable at January 31, 2013		1,316		$	10.94		4.88	$	6,158
Vested and expected to vest at January 31, 2013		1,424		$	11.44		5.20	$	6,192

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the fourth quarter of fiscal 2013 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on January 31, 2013. This amount changes based upon the market value of the Company’s common stock. Total intrinsic value of options exercised for the fiscal years ended January 31, 2013 and 2012 was $2,529,000 and $4,097,000, respectively. The fair value of options that vested during the fiscal years ended January 31, 2013, 2012 and 2011 was approximately $1,268,000, $1,195,000 and $1,301,000, respectively. For the fiscal year ended January 31, 2013, approximately 245,000 options vested.

As of January 31, 2013, there was approximately $424,000 of total unrecognized compensation expense related to unvested stock options granted under the Company’s share-based compensation plans. That expense is expected to be recognized over a weighted average period of 0.7 years.

During the fiscal year ended January 31, 2013, $329,000 was received from the exercise of options.

Restricted stock as of January 31, 2013 and changes during the fiscal year ended January 31, 2013 were as follows:


	Year Ended January 31, 2013
	Number of Shares (in thousands)			Weighted Average Grant Date Fair Value
Unvested, beginning of period		36			10.47
Granted		49			18.73
Vested		(49	)		13.52
Canceled		—			—

Unvested, end of period		36			17.59

As of January 31, 2013, there was approximately $260,000 of unrecognized stock-based compensation expense related to unvested restricted stock awards. That expense is expected to be recognized over a weighted average period of 0.7 years.

Leases [Abstract]

Leases

16. Leases

The Company leases seismic equipment to customers under operating leases with non-cancelable terms of one year or less. These leases are generally renewable on a month-to-month basis. All taxes (other than income taxes) and assessments are the contractual responsibility of the lessee. To the extent that foreign taxes are not paid by the lessee, the relevant foreign taxing authorities might seek to collect such taxes from the Company. Under the terms of its lease agreements, any amounts paid by the Company to such foreign taxing authorities may be billed and collected from the lessee. If the Company is unable to collect the foreign taxes it paid on behalf of its lessees, the Company may have foreign tax credits in the amounts paid, which could be applied against its U.S. income tax liability subject to certain limitations. The Company is not aware of any foreign tax obligations as of January 31, 2013 and 2012 that are not reflected in the accompanying consolidated financial statements.

The Company leases seismic equipment, as well as other equipment from others under operating leases. Lease expense incurred by the Company in connection with such leases amounted to approximately $1,798,000, $1,634,000 and $755,000 for the fiscal years ended January 31, 2013, 2012 and 2011, respectively.

The Company leases its office and warehouse facilities in Canada, Australia, Singapore, United Kingdom and Russia under operating leases. Office rental expense for the fiscal years ended January 31, 2013, 2012 and 2011 was approximately $1,528,000, $1,199,000 and $1,007,000, respectively.

Aggregate minimum lease payments for non-cancelable operating leases are as follows (in thousands):

Concentrations [Abstract]

Concentrations

17. Concentrations

Credit Risk—As of January 31, 2013 and 2012, amounts due from customers that exceeded 10% of consolidated accounts receivable amounted to an aggregate of approximately $9,591,000 from three customers and $8,346,000 from two customers, respectively.

The Company maintains deposits and certificates of deposit with banks which may exceed the Federal Deposit Insurance Corporation (“FDIC”) insured limit and money market accounts which are not FDIC insured. In addition, deposits aggregating approximately $15,951,000 at January 31, 2013 are held in foreign banks. Management believes the risk of loss in connection with these accounts is minimal.

Industry Concentration—The Company’s revenues are derived from seismic equipment leased and sold to companies providing seismic acquisition services. The seismic industry has historically been subject to cyclical activity and is dependent, in large part, on the expected future prices of oil and natural gas. Should the industry experience a decline in the price of oil and natural gas, the Company could be subject to significantly greater credit risk and declining demand for its products and services.

Supplier Concentration—The Company purchases the majority of its seismic equipment for its lease pool from a small number of suppliers, each being an industry leader for its product. The Company believes that two of its suppliers manufacture most of the land-based seismic systems and equipment in use. The Company has satisfactory relationships with its suppliers. However, should those relationships deteriorate, the Company may have difficulty in obtaining new technology requested by its customers and maintaining the existing equipment in accordance with manufacturers’ specifications.

- Definition

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
