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”), and its wholly owned subsidiary, Klein Marine Systems, Inc. (“Klein”), 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 New Hampshire, 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, 2016 and 2015 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 occasionally 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. Repair and maintenance is recognized as incurred.

Revenue Recognition of Equipment Sales—Revenues and cost of sales from the sale of equipment are recognized upon acceptance of terms and when delivery has occurred, unless there is a question as to 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 and Klein enter into contracts whereby they assemble and sell 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. Revenues from service contracts for each of the three years ended January 31, 2016 were not material. Due to immateriality, service revenues are not presented separately in the financial statements.

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 industry conditions, 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. The Company generally does not charge interest on past due accounts.

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. Depreciation of equipment commences upon its initial deployment on a lease contract and continues uninterrupted from that point, regardless of whether the equipment is subsequently on a lease contract.

Property and Equipment—Property and equipment is carried at cost, net of accumulated depreciation. Depreciation is computed on the straight-line method over the 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 (for customer relationships, the straight-line method is not materially different from other methods that estimate run off of the underlying customer base) over the estimated life of the asset. Proprietary rights developed technology and amortizable trade names are amortized over a 10 to 15-year period. Customer relationships are amortized over an 8-year period. Patents are amortized over an 8 to 9-year period.

Impairment—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.

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, 2016, 2015 and 2014, warranty expense was not material.

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 positive and negative 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;

•

our history of taxable income within a particular jurisdiction;

•

any history of the expiration of deferred tax assets without realization;

•

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

•

other limitations on the utilization 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;

•

our 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; and

•

tax planning strategies that will create additional taxable income.

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, valuation of assets acquired and liabilities assumed in business combinations 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 accounts and contracts receivable, accounts payable and amounts outstanding under our credit facilities. Due to the short maturities of these financial instruments and the variable rates under our credit agreements, the Company believes that their fair value approximates their carrying amounts.

The Financial Accounting Standards Board (FASB) has issued guidance on the definition of fair value, the framework for using fair value to measure assets hierarchy, which prioritizes the inputs used to measure fair value. These tiers include:

•

Level 1: Defined as observable inputs such as quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

•

Level 2: Defined as pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current and contractual prices for the underlying instruments, as well as other relevant economic measures.

•

Level 3: Defined as pricing inputs that are unobservable form objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value.

The Company measures the fair values of goodwill, intangibles and other long-lived assets on a recurring basis if required by impairment tests applicable to these assets. The Company utilized Level 3 inputs to value goodwill, intangibles and other long-lived assets as of January 31, 2016. See Notes 7 and 8 to our consolidated financial statements.

Foreign Currency Translation—All balance sheet accounts of the Canadian, Australian, certain Singaporean, United Kingdom and Russian subsidiaries 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.

Change in Functional Currency—Effective February 1, 2014, MML, MEL, Mitcham Holdings, Ltd. (“MHL”) and our branch operation in Colombia changed their functional currency to the U.S. dollar from their local currencies. At that time it was determined that the economic environment had changed for these entities due to the following factors:

•

The majority of customer contracts and cash receipts would be from that point forward denominated in U.S. dollars

•

The majority of costs from that point forward would consist primarily of purchases and the sub-lease of equipment from related entities. All such inter-company transactions are denominated in U.S. dollars.

•

Financing of these entities would be provided through inter-company borrowing arrangements that are denominated in U.S. dollars.

Stock-Based Compensation—Stock-based compensation expense is recorded based on the grant date fair value of share-based awards. Restricted stock awards are valued at the closing price on the date of grant. Determining the grant date fair value for options 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 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, 2016, 2015 and 2014, the following table sets forth the number of potentially dilutive shares that may be issued pursuant to options, restricted stock and warrants outstanding used in the per share calculations.


	Years Ended January 31,
	2016		2015		2014
	(in thousands)
Stock options		13		223		389
Restricted stock		46		26		25

Total dilutive shares		59		249		414

Anti-dilutive weighted average shares of potential common stock of 501,000 for the fiscal year ended January 31, 2014 have been excluded from the effect of dilutive shares. For the fiscal years ended January 31, 2016 and 2015, respectively, potentially dilutive common shares, underlying stock options and unvested restricted stock were anti-dilutive and were therefore not considered in calculating diluted loss per share for those periods.

New Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-9, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, to reduce complexity in accounting standards involving several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU No. 2016-9 will be effective during the fiscal year ended January 31, 2018. The Company is currently evaluating the impact of ASU No. 2016-9 on its financial statements. In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-2, Leases: (Topic 842), to provide guidance on recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements, specifically differentiating between different types of leases. ASU No. 2016-2 will be effective during the fiscal year ended January 31, 2019. The Company is currently evaluating the impact of ASU No. 2016-2 on its financial statements. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes: (Topic 740), requiring that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. Effective January 31, 2016 the Company has adopted the provisions of ASU 2015-17 on a prospective basis. Accordingly, all net deferred tax assets are classified as long-term assets as of January 31, 2016 in the accompanying Consolidated Balance Sheets. Amounts for prior periods have not been restated. The provisions of this pronouncement have been adopted in order to simplify the presentation of deferred income taxes. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations: (Topic 805), to provide guidance on the simplification of the accounting for adjustments made to provisional amounts recognized in a business combination, eliminating the requirement to retrospectively account for those adjustments. ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendment requires that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendment further requires presentation separately on the face of the income statement or disclosure in the notes to the financial statements of the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 will be effective during the fiscal year ended January 31, 2017. The Company does not believe the adoption will have a material effect on its financial statements. In August 2015, the FASB issued ASU No. 2015-15, Interest-Imputation of Interest: (Subtopic 835-30), to provide guidance on measurement of debt issuance costs associated with line-of-credit arrangements. ASU 2015-15 allows debt issuance costs associated with line-of-credit arrangements to be deferred and presented as an asset and subsequently amortized ratably over the term of the line-of-credit arrangement. ASU 2015-15 will be effective during the fiscal year ended January 31, 2017. The Company does not believe the adoption will have a material effect on its financial statements. In July 2015, the FASB issued ASU No. 2015-11, Inventory: (Topic 330), to provide guidance on measurement of inventory. ASU 2015-11 requires that inventories utilizing the first-in, first-out (FIFO) method be measured at lower of cost or net realizable value. ASU 2015-11 will be effective during the fiscal year ended January 31, 2018. The Company does not believe the adoption will have a material effect on its financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: (Topic 606), to provide guidance on revenue recognition on contracts with customers to transfer goods or services or on contracts for the transfer of nonfinancial assets. ASU 2014-09 requires that revenue recognition on contracts with customers depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will be effective during the fiscal year ended January 31, 2019. The Company does not believe the adoption will have a material effect on its financial statements.

Business Combinations [Abstract]

Acquisition

3. Acquisition

In December 2015, the Company purchased Klein, a designer, manufacturer and worldwide distributor of sonar and waterside security systems to military and commercial customers, for $10 million in cash. Klein’s product lines consist of single and multi-beam side scan sonar systems. The Company made this acquisition to expand the product offerings available to customers, gain access to additional technology, expand the markets in which it operates and to reduce the Company’s dependence on the cyclical energy industry.

The Company estimated fair values for assets acquired utilizing management estimates with the assistance of an independent appraisal firm. The value of tangible property was estimated using a combination of cost and sales comparison approaches. The value of identifiable intangible assets was estimated generally using an income approach. This approach utilized inputs that are not observable in the market and thus represents a Level 3 fair value measurement. Key assumptions include management’s estimates of revenue and costs associated with various intangible assets and the discount rate applied to those revenues and costs.

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


Working capital	$	2,572
Property, plant and equipment		3,416
Intangible assets		2,350
Goodwill		1,662

Intangible assets include trade names of approximately $760,000, which have an indefinite useful life and are not amortizable. The weighted average useful life of other acquired intangibles is 9.5 years.

The goodwill associated with this acquisition is deductible for tax purposes.

Revenue and net income for Klein were $533,000 and $5,000, respectively, for the month ended January 31, 2016. The operations of Klein are included in our Equipment Manufacturing and Sales segment.

Pro Forma Results of Operations

The following consolidated pro forma results of operations for the years ended January 31, 2016 and 2015 assumes the acquisition of Klein occurred as of the beginning of those periods and reflects the full results of operations for the periods presented. The consolidated pro forma results have been prepared for comparative purposes only and do not purport to indicate the results of operations that would actually have occurred had the combinations been in effect on the dates indicated, or that may occur in the future.

In May 2014, the Company’s wholly-owned subsidiary, Seamap Pte Ltd (“Seamap Singapore”), purchased two product lines from ION Geophysical Corporation (“ION”) for $14.5 million in cash and a credit of $2.0 million against future sales or rentals. These product lines consist of the Digishot^® energy source controller and the Sleeve Gun energy sources, collectively the “ION Source Products”. The Company made this acquisition to expand the product offerings available to customers, gain access to additional technology and expand the markets in which it operates. The Company accounted for this transaction as a business combination and these operations are included in the Seamap segment. Based on an independent valuation study, the fair value of the consideration was determined to be approximately $15.6 million and was allocated as follows: $10.0 million to amortizable intangible assets (including customer relationships of $5.1 million, property rights of $2.9 million and patents of $2.0 million), $3.6 million to inventory, $1.4 million to goodwill and $600,000 to furniture and fixtures. The goodwill is not deductible for tax purposes. Pro forma results of operations have not been presented as the business combination was not significant.

In December of 2015, the Company acquired $1.7 million in goodwill and $2.4 million in other intangible assets in connection with the purchase of Klein. See note 3 to our consolidated financial statements.

On January 31, 2016 the Company completed the annual review of goodwill and other intangible assets. Based on a review of qualitative factors it was determined it was more likely than not that the carrying value of our reporting units was greater than their fair value. Therefore a quantitative assessment was conducted using Level 3 inputs including projections of earnings and comparable multiples of earnings. The review indicated that the carrying value of the Seamap reporting unit, including goodwill, exceeded its fair value. This required the Company to perform step 2 of the impairment test on the Seamap reporting unit, which indicated that the goodwill associated with the Seamap reporting unit was impaired. Accordingly, the Company recorded an impairment of the goodwill associated with this reporting unit in the amount of $3.0 million. Also at January 31, 2016, the Company recorded impairment of approximately $600,000 related to certain identifiable intangible assets related to its leasing reporting unit.

Aggregate amortization expense was $1.7 million, $1.4 million and $660,000 for the fiscal years ended January 31, 2016, 2015 and 2014, respectively. As of January 31, 2016, future estimated amortization expense related to amortizable intangible assets is estimated to be (in thousands):


For fiscal years ending January 31:

2018		1,418

On August 2, 2013, the Company entered into a $50.0 million, three-year revolving credit facility, as described below (the “Credit Agreement”). The Credit Agreement replaced a predecessor revolving credit facility with First Victoria National Bank. The Credit Agreement is a three-year, secured revolving facility in the maximum principal amount of $50.0 million, among the Company, as borrower, HSBC Bank USA, N.A., as administrative agent and several banks and other financial institutions from time to time as lenders thereunder (initially consisting of HSBC Bank USA, N.A. and First Victoria National Bank). In December 2015, the Credit Agreement was amended to (a) extend the maturity date to August 31, 2017, (b) reduce the amount of the commitment to $40.0 million from $50.0 million and (c) amend the definition of Adjusted EBITDA to exclude certain non-recurring contract settlement costs. In February 2015, the Company elected to further reduce the commitment to $30.0 million, as provided for in the Credit Agreement.

In December 2015, the Credit Agreement was amended to: (a) extend the maturity date to August 31, 2017; (b) reduce the amount of the commitment to $40.0 million from $50.0 million; and (c) amend the definition of Adjusted EBITDA to exclude certain non-recurring contract settlement costs. In February 2016, the Company elected to further reduce the commitment to $30.0 million, as provided for in the Credit Agreement.

Amounts available for borrowing under the Credit Agreement are determined by a borrowing base. The borrowing base is determined primarily based upon the appraised value of the Company’s domestic lease pool equipment and certain accounts receivable. The Credit Agreement is collateralized by essentially all of the Company’s domestic assets (other than real estate) and 65% of the capital stock of Mitcham Holdings, Ltd., a foreign holding company and wholly owned subsidiary of the Company that holds the capital stock of the Company’s foreign subsidiaries.

The Credit Agreement provides interest at a base rate, or for Eurodollar borrowings, in both cases plus an applicable margin. As of January 31, 2016, the base rate margin was 250 basis points and the Eurodollar margin was 350 basis points. The Company has agreed to pay a commitment fee on the unused portion of the Credit Agreement of 0.375% to 0.5%. Up to $10.0 million of available borrowings under the Credit Agreement may be utilized to secure letters of credit. The Credit Agreement contains certain financial covenants that require, among other things, that the Company maintain a leverage ratio, which is calculated at the end of each quarter, of no greater than 2.00 to 1.00 on a trailing four quarter basis and a fixed charge coverage ratio, which also is calculated at the end of each quarter, of no less than 1.25 to 1.00 on a trailing four quarter basis. In addition, should Adjusted EBITDA, as defined in the Credit Agreement, for any trailing four quarter period be less than $22.0 million, the ratio of capital expenditures to Adjusted EBITDA for that four quarter period may not be greater than 1.0 to 1.0. The Credit Agreement also includes restrictions on additional indebtedness in excess of $5.0 million. The Company was in compliance with each of these provisions as of and for the fiscal year ended January 31, 2016.

The Credit Agreement contains customary representations, warranties, conditions precedent to credit extensions, affirmative and negative covenants and events of default. The negative covenants include restrictions on liens, additional indebtedness in excess of $5.0 million, acquisitions, fundamental changes, dispositions of property, restricted payments, and transactions with affiliates and lines of business. The events of default include a change in control provision.

On August 22, 2014, Seamap Singapore, entered into a $15.0 million credit facility (the “Seamap Credit Facility”) with The Hongkong and Shanghai Banking Corporation Limited (“HSBC-Singapore”). The facility consists of a $10.0 million term loan, a $3.0 million revolving credit facility, and a $2.0 million banker’s guarantee facility.

The term loan portion of the Seamap Credit Facility provides for eleven quarterly principal payments of $800,000 and a final payment of the remaining $1.2 million on or before August 22, 2017. Interest on the term facility is payable quarterly at LIBOR plus 2.75%. Under the Seamap Credit Facility, Seamap Singapore may borrow up to $3.0 million for a period of one to three months to be utilized for working capital and other general corporate purposes. Borrowings under the revolving credit facility bear interest at LIBOR plus 3.00%. Borrowings under this arrangement are secured by essentially all of the assets of Seamap Singapore and the Company’s guarantee.

The Seamap Credit Facility contains financial covenants that require Seamap Singapore to maintain a minimum shareholder’s equity of S$15 million and a minimum ratio of debt to EBITDA of not less than 125% for each fiscal year. The Company was in compliance with each of these provisions as of and for the fiscal years ended January 31, 2015.

The Seamap Credit Facility contains customary representations and warranties, conditions precedent to credit extensions, affirmative and negative covenants and events of default. The negative covenants include restrictions on liens, additional indebtedness, acquisitions, fundamental changes, dispositions of property, restricted payments, and transactions with affiliates. The Seamap Credit Facility also requires the Company, as guarantor, to comply with financial covenants contained in the Credit Agreement.

The Company’s average borrowings under the Credit Agreement and the Seamap Credit Facility for the fiscal years ended January 31, 2016 and 2015 were approximately $17.6 million and $26.3 million, respectively.

From time to time, certain subsidiaries have entered into notes payable to finance the purchase of certain equipment, which is pledged as security for the notes payable.

The Company has determined that the undistributed earnings of foreign subsidiaries, other than branch operations in Colombia and Peru, as of January 31, 2016, have been permanently reinvested outside of the United States. These permanent investments include the purchase of lease pool equipment by those subsidiaries and other investments. Accordingly, no deferred tax liability has been recognized related to these undistributed earnings. As of January 31, 2016, the unrecognized deferred tax liability related to these items amounts to approximately $4.2 million.

Effective January 31, 2016 the Company has adopted the provisions of ASU 2015-17 on a prospective basis. Accordingly, all net deferred tax assets are classified as long-term assets as of January 31, 2016 in the accompanying Consolidated Balance Sheets. Amounts for prior periods have not been restated. The provisions of this pronouncement have been adopted in order to simplify the presentation of deferred income taxes.

Included in deferred tax assets is approximately $2.7 million related to stock based compensation, including non-qualified stock options. Recent prices for the Company’s common stock are below the exercise price for a significant number of these stock options. Should the price of the Company’s common stock remain below the exercise price of the options, these stock options will expire without exercise. In accordance with the provisions of ASC 718-740-10, a valuation allowance has not been computed based on the decline in stock price.

As of January 31, 2016, the Company has recorded valuation allowances of approximately $16.7 million related to deferred tax assets. These deferred tax assets relate primarily to net operating loss carryforwards in the United States and other jurisdictions. The valuation allowances were determined based on management’s judgment as to the likelihood that these deferred tax assets would be realized. The judgment was based on an evaluation of available evidence, both positive and negative.

In the fiscal year ended January 31, 2016, the cumulative book expense related to stock-based compensation awards exceeded the tax deduction related to these awards. Accordingly, the deferred tax asset related to these awards was reduced by the tax effect of approximately $416,000, which amount reduced paid-in capital. In the fiscal year ended January 31, 2015, the tax deduction related to stock-based compensation awards exceeded the cumulative book expense related to these awards. The associated tax benefit, which amounted to approximately $123,000, will be recognized as additional paid-in capital upon the realization of this benefit. In the fiscal year ended January 31, 2014, the cumulative book expense related to stock-based compensation awards exceeded the tax deduction related to these awards. Accordingly, the deferred tax asset related to these awards was reduced by the tax effect of approximately $5,000, which reduced paid-in capital.

At January 31, 2016, the Company had foreign withholding tax credit carry forwards of approximately $823,000, which amounts can be carried forward through at least 2021.

As of January 31, 2015, the Company had unrecognized tax benefits amounting to approximately $237,000 attributable to uncertain tax positions. There were no such amounts as of January 31, 2016. 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 $145,000 as of January 31, 2015. Included in income tax expense for the fiscal years ended January 31, 2016, 2015 and 2014 are benefits related to a reduction in estimated potential penalties and interest of approximately $145,000, $10,000 and $222,000, respectively. 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, 2013 through 2016. The Company’s tax returns may also be subject to examination by state and local revenue authorities for fiscal years ended January 31, 2011 through 2016. The Company’s Canadian income tax returns are subject to examination by the Canadian tax authorities for fiscal years ended January 31, 2012 through 2016.

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

Stock Option Plans

13. Stock Option Plans

At January 31, 2016, the Company had stock-based compensation plans as described in more detail below. The total compensation expense related to stock-based awards granted under these plans during the fiscal years ended January 31, 2016, 2015 and 2014 was approximately $1.3 million, $1.3 million and $1.1 million, respectively. The Company recognizes stock-based compensation costs net of a forfeiture rate for only those awards 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 not paid any dividends since its incorporation. The weighted average grant-date fair value of options granted during the fiscal years ended January 31, 2016, 2015 and 2014 was $1.64, $6.23 and $14.63, 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,
	2016	2015	2014
Risk free interest rate	1.34 - 1.55%	1.63%	0.83%
Expected life	4.87 - 6.87 yrs	4.70 - 6.70 yrs	5.62 yrs
Expected volatility	50 - 52%	47%	60%
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 out-flows and operating in-flows. The Company had excess tax benefits of approximately $416,000 and $5,000 during the fiscal years ended January 31, 2016 and 2014, respectively.

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, 2016, there were approximately 138,000 shares 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, 2016:


	Number of Shares (in thousands)			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (in thousands)
Outstanding, January 31, 2015		1,406		$	12.85		4.32	$	200
Granted		828			4.03
Exercised		—			—
Forfeited		(15	)		5.00
Expired		(261	)		10.19

Outstanding, January 31, 2016		1,958		$	9.54		6.31	$	—

Exercisable at January 31, 2016		1,196		$	10.03		4.36	$	—
Vested and expected to vest at January 31, 2016		1,900		$	8.14		6.26	$	—

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 2016 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, 2016. This amount changes based upon the market value of the Company’s common stock. No options were exercised during the fiscal year ended January 31, 2016. Total intrinsic value of options exercised for the fiscal year ended January 31, 2015 was $509,000. The fair value of options that vested during the fiscal years ended January 31, 2016, 2015 and 2014 was approximately $1.5 million, $1.2 million and $601,000, respectively. For the fiscal year ended January 31, 2016, approximately 272,000 options vested.

As of January 31, 2016, there was approximately $1.0 million 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 1.6 years.

Restricted stock as of January 31, 2016 and changes during the fiscal year ended January 31, 2016 were as follows:


	Year Ended January 31, 2016
	Number of Shares (in thousands)			Weighted Average Grant Date Fair Value
Unvested, beginning of period		66		$	14.19
Granted		7			4.07
Vested		(41	)		14.22
Canceled		—			—

Unvested, end of period		32		$	11.89

As of January 31, 2016, there was approximately $104,000 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 0.8 years.

In accordance with ASC 280-10-50, the Company has restated prior year’s financial information to reflect the change in reporting segments.

The Equipment Leasing segment offers for lease or sale, new and “experienced” seismic equipment to the oil and gas industry, seismic contractors, environmental agencies, government agencies and universities. The Equipment Leasing segment is headquartered in Huntsville, Texas, with sales and services offices in Calgary, Canada; Singapore; Brisbane, Australia; and Ufa, Bashkortostan, Russia.

The Equipment Manufacturing and Sales segment is engaged in the design, manufacture and sale of state-of-the-art seismic and offshore telemetry systems. Manufacturing, support and sales facilities are maintained in the UK, Singapore and New Hampshire, with sales offices in Huntsville, Texas and Brisbane, Australia.

Financial information by business segment is set forth below net of any allocations (in thousands):

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, 2016 and 2015 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 $831,000, $1.4 million and $621,000 for the fiscal years ended January 31, 2016, 2015 and 2014, respectively.

The Company leases its office and warehouse facilities in Canada, Australia, Singapore, United Kingdom, Hungary, Colombia and Russia under operating leases. Office rental expense for the fiscal years ended January 31, 2016, 2015 and 2014 was approximately $1.2 million, $1.4 million and $1.4 million, respectively.

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

Risks and Uncertainties [Abstract]
Concentrations	17. Concentrations Credit Risk—As of January 31, 2016 and 2015, amounts due from customers that exceeded 10% of consolidated accounts receivable amounted to an aggregate of approximately $11.6 million from four customers and $11.3 million from three 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 $3.1 million at January 31, 2016 are held in foreign banks. Management believes the risk of loss in connection with these accounts is minimal. Industry Concentration— The majority of 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization

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”), and its wholly owned subsidiary, Klein Marine Systems, Inc. (“Klein”), 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 New Hampshire, Singapore and the United Kingdom.

Cash and Cash Equivalents

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

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

Seismic Equipment Lease Pool

Property and Equipment

Intangible Assets

Impairment

Impairment—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.

New Accounting Pronouncements

New Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-9, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, to reduce complexity in accounting standards involving several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU No. 2016-9 will be effective during the fiscal year ended January 31, 2018. The Company is currently evaluating the impact of ASU No. 2016-9 on its financial statements.

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-2, Leases: (Topic 842), to provide guidance on recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements, specifically differentiating between different types of leases. ASU No. 2016-2 will be effective during the fiscal year ended January 31, 2019. The Company is currently evaluating the impact of ASU No. 2016-2 on its financial statements.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes: (Topic 740), requiring that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. Effective January 31, 2016 the Company has adopted the provisions of ASU 2015-17 on a prospective basis. Accordingly, all net deferred tax assets are classified as long-term assets as of January 31, 2016 in the accompanying Consolidated Balance Sheets. Amounts for prior periods have not been restated. The provisions of this pronouncement have been adopted in order to simplify the presentation of deferred income taxes.

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations: (Topic 805), to provide guidance on the simplification of the accounting for adjustments made to provisional amounts recognized in a business combination, eliminating the requirement to retrospectively account for those adjustments. ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendment requires that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendment further requires presentation separately on the face of the income statement or disclosure in the notes to the financial statements of the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 will be effective during the fiscal year ended January 31, 2017. The Company does not believe the adoption will have a material effect on its financial statements.

In August 2015, the FASB issued ASU No. 2015-15, Interest-Imputation of Interest: (Subtopic 835-30), to provide guidance on measurement of debt issuance costs associated with line-of-credit arrangements. ASU 2015-15 allows debt issuance costs associated with line-of-credit arrangements to be deferred and presented as an asset and subsequently amortized ratably over the term of the line-of-credit arrangement. ASU 2015-15 will be effective during the fiscal year ended January 31, 2017. The Company does not believe the adoption will have a material effect on its financial statements.

In July 2015, the FASB issued ASU No. 2015-11, Inventory: (Topic 330), to provide guidance on measurement of inventory. ASU 2015-11 requires that inventories utilizing the first-in, first-out (FIFO) method be measured at lower of cost or net realizable value. ASU 2015-11 will be effective during the fiscal year ended January 31, 2018. The Company does not believe the adoption will have a material effect on its financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: (Topic 606), to provide guidance on revenue recognition on contracts with customers to transfer goods or services or on contracts for the transfer of nonfinancial assets. ASU 2014-09 requires that revenue recognition on contracts with customers depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will be effective during the fiscal year ended January 31, 2019. The Company does not believe the adoption will have a material effect on its financial statements.
