1.                                     Description of Business and Basis of Presentation
 
Description of Business
 
Mistras Group, Inc. and subsidiaries (the Company)("the Company") is a leading “one source” global provider of technology-enabled asset protection solutions used to evaluate the structural integrity and reliability of critical energy, industrial and public infrastructure. The Company combines industry-leading products and technologies, expertise in mechanical integrity (MI) and non-destructive testing (NDT) services and proprietary data analysis software to deliver a comprehensive portfolio of customized solutions, ranging from routine inspections to complex, plant-wide asset integrity assessments and management. These mission critical solutions enhance customers’ ability to extend the useful life of their assets, increase productivity, minimize repair costs, comply with governmental safety and environmental regulations, manage risk and avoid catastrophic disasters. The Company serves a global customer base of companies with asset-intensive infrastructure, including companies in the oil and gas, fossil and nuclear power, alternative and renewable energy, public infrastructure, chemicals, commercial aerospace and defense, transportation, primary metals and metalworking, pharmaceutical/biotechnology and food processing industries and research and engineering institutions.
 
Basis of Presentation
 
The condensed consolidated financial statements contained in this report are unaudited. In the opinion of management, the condensed consolidated financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the results for the interim periods of the fiscal years ending May 31, 20152016 and 2014.2015. Reference to a fiscal year means the fiscal year ended May 31. Certain items included in these statements are based on management’s estimates. Actual results may differ from those estimates. The results of operations for any interim period are not necessarily indicative of the results expected for the year. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the notes to the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K (“2015 Annual Report”) for fiscal 2014,2015, as filed with the Securities and Exchange Commission on August 8, 2014.12, 2015.
 
Principles of Consolidation
 
The accompanying unaudited condensed consolidated financial statements include the accounts of Mistras Group, Inc. and its wholly and majority-owned subsidiaries. For subsidiaries in which the Company’s ownership interest is less than 100%, the noncontrolling interests are reported in stockholders’ equity in the accompanying condensed consolidated balance sheets. The noncontrolling interests in net income, net of tax, is classified separately in the accompanying condensed consolidated statements of income.
 
All significant intercompany accounts and transactions have been eliminated in consolidation. Mistras Group, Inc.’s and its subsidiaries’ fiscal years end on May 31 except for the subsidiaries in the International segment, which end on April 30. Accordingly, the Company’s International segment subsidiaries are consolidated on a one month lag. Therefore, in the quarter and year of acquisition, results of acquired subsidiaries in the International segment are generally included in consolidated results for one less month than the actual number of months from the acquisition date to the end of the reporting period. Management does not believe that any events occurred during the one-month lag period that would have a material effect on the Company’s condensed consolidated financial statements.

Reclassification

Certain amounts in prior periods have been reclassified to conform to the current year presentation. Such reclassifications did not have a material effect on the Company’sCompany's financial condition or results of operations as previously reported.

and concluded that the errors were immaterial. Accordingly, management has corrected the presentation of the affected line items of the accompanying Condensed Consolidated Statement of Cash Flows for the nine months ended February 28, 2015, as summarized below. These changes did not impact the Company’s net income, balance sheet, or stockholders’ equity for any periods previously reported.

Significant Accounting Policies
The Company’s significant accounting policies are disclosed in Note 2 — Summary of Significant Accounting Policies in the Company's 2015 Annual Report. On an ongoing basis, the Company evaluates its estimates and assumptions, including, among other things those related to revenue recognition, valuations of accounts receivable, long-lived assets, goodwill, deferred tax assets and uncertain tax positions. Since the date of the 2015 Annual Report, there have been no material changes to the Company's significant accounting policies.

Income Taxes

The Company provides for income taxes in interim periods in an amount that aligns its year-to-date tax provision with the effective income tax rate expected for the full year, plus adjustments to certain discrete tax items. During the three months ended February 29, 2016 and February 28, 2015, the Company's effective income tax rate differed from the statutory rate principally due to adjustments to certain discrete tax items related to the resolution and adjustment of certain income tax contingencies, which decreased the effective tax rate by 11% and 8%, respectively.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (ASU)ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2016.2017, as a result of a one year deferral in the standard issued by the FASB in August 2015 with ASU 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures.

3.                                     Earnings per Share
 
Basic earnings per share is computed by dividing net income by the weighted-average number of shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the sum of (1) the weighted-average number of shares of common stock outstanding during the period, and (2) the dilutive effect of assumed conversion of equity awards using the treasury stock method. With respect to the number of weighted-average shares outstanding (denominator), diluted shares

Senior Credit Facility
 
On October 31, 2014, the Company entered into a Third Amendment and Modification Agreement, (the “Amendment”), to its revolving line of credit, the Third Amended and Restated Credit Agreement (“Credit Agreement”), dated December 21, 2011, with Bank of America, N.A., as agent for the lenders and a lender, and JPMorgan Chase Bank, N.A., Keybank, National Association and TD Bank, N.A., as lenders. The Amendment increasedCredit Agreement provides the Company’sCompany with a $175.0 million revolving line of credit, to from $125.0 million to $175.0 million and provides thatwhich, under certain circumstances, the line of credit can be increased to $225.0 million. The Company may continue to borrow up to $30.0 million in non-U.S. Dollar currencies and use up to $10.0 million of the credit limit for the issuance of letters of credit. The Amendment also extended the originalCredit Agreement has a maturity date of the Credit Agreement from December 20, 2016 to October 30, 2019. As of February 28, 2015,29, 2016, the Company had borrowings of $96.7$71.5 million and a total of $4.7$4.5 million of letters of credit outstanding under the Credit Agreement.
 
Loans under the Credit Agreement bear interest at LIBOR plus an applicable LIBOR margin ranging from 1% to 1.75%, or a base rate less a margin of 1.25% to 0.375%, at the option of the Company, based upon the Company’s Funded Debt Leverage Ratio. Funded Debt Leverage Ratio is generally the ratio of (1) all outstanding indebtedness for borrowed money and other interest-bearing indebtedness as of the date of determination to (2) EBITDA (which is (a) net income, less (b) income (or plus loss) from discontinued operations and extraordinary items, plus (c) income tax expenses, plus (d) interest expense, plus (e) depreciation, depletion, and amortization (including non-cash loss on retirement of assets), plus (f) stock compensation expense, less (g) cash expense related to stock compensation, plus or minus certain other adjustments) for the period of four consecutive fiscal quarters immediately preceding the date of determination. The Company has the benefit of the lowest margin if its Funded Debt Leverage Ratio is equal to or less than 0.5 to 1, and the margin increases as the ratio increases, to the maximum margin if the ratio is greater than 2.0 to 1. The Company will also bear additional costs for market disruption, regulatory changes effecting the lenders’ funding costs, and default pricing of an additional 2% interest rate margin on any amounts not paid when due. Amounts borrowed under the Credit Agreement are secured by liens on substantially all of the assets of the Company.
 
The Credit Agreement contains financial covenants requiring that the Company maintain a Funded Debt Leverage Ratio of no greater than 3.25 to 1 and an Interest Coverage Ratio of at least 3.0 to 1. Interest Coverage Ratio means the ratio, as of any date

The Credit Agreement contains financial covenants requiring that the Company maintain a Funded Debt Leverage Ratio of no greater than 3.0 to 1 and an Interest Coverage Ratio of at least 3.0 to 1. Interest Coverage Ratio means the ratio, as of any date of determination, of (a) EBITDA for the 12 month period immediately preceding the date of determination, to (b) all interest, premium payments, debt discount, fees, charges and related expenses of the Company and its subsidiaries in connection with borrowed money (including capitalized interest) or in connection with the deferred purchase price of assets, in each case to the extent treated as interest in accordance with GAAP, paid during the 12 month period immediately preceding the date of determination. The Credit Agreement also limits the Company’s ability to, among other things, create liens, make investments, incur more indebtedness, merge or consolidate, make dispositions of property, pay dividends and make distributions to stockholders, enter into a new line of business, enter into transactions with affiliates and enter into burdensome agreements. The Credit Agreement does not limit the Company’s ability to acquire other businesses or companies except that the acquired business or company must be in the Company's line of business, the Company must be in compliance with the financial covenants on a pro forma basis after taking into account the acquisition, and, if the acquired business is a separate subsidiary, in certain circumstances the lenders will receive the benefit of a guaranty of the subsidiary and liens on its assets and a pledge of its stock.
 
As of February 28, 2015,29, 2016, the Company was in compliance with the terms of the Credit Agreement, and will continuously monitor its compliance with the covenants contained in its credit agreement.
 
Notes Payable and Other
 
In connection with certain of its acquisitions through fiscal 2015, the Company issued subordinated notes payable to the sellers. The maturity of the notes that remain outstanding range from two to five years from the date of acquisition with stated interest rates ranging from 0% to 4%. The Company has discounted these obligations to reflect a 2% to 4% market interest. Unamortized discount on the notes was de minimis as of February 28, 201529, 2016 and May 31, 2014.2015. Amortization is recorded as interest expense in the condensed consolidated statements of income.
 
The Company has evaluated current market conditions and borrower credit quality and has determined that the carrying value of its long-term debt approximates fair value. The fair value of the Company’s notes payable and capital lease obligations approximates their carrying amounts based on anticipated interest rates which management believes would currently be available to the Company for similar issuesissuances of debt.
 
10.11.                              Fair Value Measurements
 
The Company performs fair value measurements in accordance with the guidance provided by ASC 820, Fair Value Measurements and Disclosures. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It also establishes a three level hierarchy that prioritizes the inputs used to measure fair value. The three levels of the hierarchy are defined as follows:
 
Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
 
Level 2 — Observable inputs other than quoted prices included in Level 1, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability and inputs derived principally from or corroborated by observable market data.
 
Level 3 — Unobservable inputs reflecting the Company’s own assumptions about inputs that market participants would use in pricing the asset or liability based on the best information available.

In accordance with the fair value hierarchy described above, the following table shows the fair value of the Company’s financial liabilities that are required to be remeasured at fair value on a recurring basis:

The fair value of contingent consideration liabilities that was classified as Level 3 in the table above was estimated using a discounted cash flow technique with significant inputs that are not observable in the market and thus represents a Level 3 fair value measurement as defined in ASC 820. The significant inputs in the Level 3 measurement not supported by market activity include the probability assessments of expected future cash flows related to the acquisitions, appropriately discounted considering the uncertainties associated with the obligation, and as calculated in accordance with the terms of the applicable acquisition agreements.

Litigation and Government Investigations
 
The Company is subject to periodic lawsuits, investigations and claims that arise in the ordinary course of business. Although the Company cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against it, the Company does not believe that any currently pending legal proceeding to which the Company is a party will have a material adverse effect on its business, results of operations, cash flows or financial condition.condition, except for the proceedings described below for which the Company is currently unable to determine the likely outcome or reasonably estimate the amount or range of potential liability estimate. The costs of defense and amounts that may be recovered against the Company in such matters may be covered by insurance.insurance, except that the primary claims set forth in the purported class action case in California is excluded from insurance coverage.

Litigation and Commercial Claims
 
In April 2015, two separate lawsuits were filed in California as purported class action lawsuits on behalf of current and former Mistras employees. The cases are David Kruger v Mistras Group, Inc., filed in the U.S. District Court for the Eastern District of California and Edgar Viceral v Mistras Group, et al, pending in the U.S. District Court for the Northern District of California. Both cases were originally filed in California state court and were removed to the respective U.S. District Courts for the districts in which the state court cases were filed. These two cases have been consolidated, with Kruger dismissing his case and joining the Viceral case. As part of this consolidation, the claims in the Kruger case that were not part of the Viceral case were added to the Viceral case by the filing of an amended complaint. The consolidated case alleges violations of California statutes primarily, the California Labor Code, and seeks to proceed as a collective action under the U.S. Fair Labor Standards Act. The case is predicated on claims for allegedly missed rest and meal periods, inaccurate wage statements, and failure to pay all wages due, as well as related unfair business practices, and is requesting payment of all damages, including unpaid wages, and various fines and penalties available under California law. The parties met with a mediator on April 5, 2016 but no resolution of the case was reached, though the Company anticipates discussions regarding resolution may continue. The Company is currently unable to determine the likely outcome or reasonably estimate the amount or range of potential liability, if any, related to these matters, and accordingly, has not established any reserves for these matters.

During fiscal 2012 and 2013, the Company performed radiography work on the construction of pipeline projects in the U.S. The Company has received notice that the owner of the pipeline projects contends that certain of the x-ray images the Company’s technicians prepared regarding the projects did not meet the code quality interpretation standards required by API (American Petroleum Institute) 1103. The projects' owner is claiming damages as a result of the alleged quality defects of the Company’s x-ray images. No lawsuit has been filed at this time. The Company is currently unable to determine the likely outcome or reasonably estimate the amount or range of potential liability related to this matter, and accordingly, has not established any reserves for this matter.
Government Investigations

In May 2015, the Company received a notice from the U.S. Environmental Protection Agency (“EPA”) that it performed a preliminary assessment at a leased facility the Company operates in Cudahy, California. Based upon the preliminary assessment, the EPA is conducting an investigation of the site, which includes taking groundwater and soil samples. The purpose of the investigation is to determine whether any hazardous materials were released from the facility. The Company has been informed that certain hazardous materials and pollutants have been found in the ground water in the general vicinity of the site and the EPA is attempting to ascertain the origination or source of these materials and pollutants. Given the historic industrial use of the site, the EPA determined that the site of the Cudahy facility should be examined, along with numerous other sites in the vicinity. At this time, the Company is unable to determine whether it has any liability in connection with this matter and if so, the amount or range of any such liability, and accordingly, has not established any reserves for this matter.

In January 2012, the Company received notice of a governmental investigation concerning an environmental incident which occurred in February 2011 outside on the premises of itsthe Cudahy California location.facility.  No human injury or property damage was reported or appears to have been caused as a result of this incident. While management cannot predict the ultimate outcome of this matter, based on its internal investigation to date, the Company does not believe the outcome will have a material effect on its financial condition or results of operations. To the Company’s knowledge, this matter has been dormant since fiscal 2012.
 
During fiscal 2012 and 2013, the Company performed radiography work on the construction of pipeline projects in Georgia. The Company has received notice that the owner of the pipeline projects contends that certain of the x-ray images the Company’s technicians prepared did not meet the code quality interpretation standards required by API (American Petroleum Institute) 1104 for one of the projects. The owner of the projects is claiming damages as a result of the alleged quality defects of the Company’s x-ray images. No lawsuit has been filed at this time. The owner has requested additional information on the other project, but has not yet indicated that any of the Company’s work was defective. The Company is currently unable to determine the likely outcome or reasonably estimate the amount or range of potential liability related to this matter, and accordingly, has not established any reserves for this matter.
The Company has received a notice from an insurance company of a chemical plant alleging that the Company is liable due to faulty inspections for all or part of $46 million of damages paid by the insurance company as a result of an explosion at the facility. The Company believes it was not involved in inspecting the portion of the plant where the explosion occurred and therefore has no liability for the claim.  Accordingly, the Company has not established a reserve for this matter.

Acquisition-related contingencies
 
The Company is liable for contingent consideration in connection with certain of its acquisitions. As of February 28, 2015,29, 2016, total potential acquisition-related contingent consideration ranged from zero to approximately $23.3$17.8 million and would be payable upon the achievement of specific performance metrics by certain of the acquired companies over the next three3.3 years of operations. See Note 4 - Acquisitions to these condensed consolidated financial statements for further discussion of the Company’s acquisitions.
 
12.13.                              Segment Disclosure
 
The Company’s three operating segments are:
 
Services. This segment provides asset protection solutions primarily in North America with the largest concentration in the United States and the Canadian services business, consisting primarily of non-destructive testing and inspection and engineering services that are used to evaluate the structural integrity and reliability of critical energy, industrial and public infrastructure.
 
International. This segment offers services, products and systems similar to those of the Company’s other two segments to global markets, principally in Europe, the Middle East, Africa, Asia and South America, but not to customers in China and South Korea, which are served by the Products and Systems segment.
 
Products and Systems. This segment designs, manufactures, sells, installs and services the Company’s asset protection products and systems, including equipment and instrumentation, predominantly in the United States.
 
Allocations for general corporate services, including accounting, audit, and contract management, that are provided to the segments are reported within Corporate and eliminations. Sales to the International segment from the Products and Systems segment and subsequent sales by the International segment of the same items are recorded and reflected in the operating performance of both segments. Additionally, engineering charges and royalty fees charged to the Services and International segments by the Products and Systems segment are reflected in the operating performance of each segment. All such intersegment transactions are eliminated in the Company’s consolidated financial reporting.
The accounting policies of the reportable segments are the same as those described in Note 1 — Description of Business and Basis of Presentation. Segment income from operations is determined based on internal performance measures used by the Chief Executive Officer, who is the chief operating decision maker, to assess the performance of each business in a given period and to make decisions as to resource allocations. In connection with that assessment, the Chief Executive Officer may exclude matters such as charges for share-based compensation and certain other acquisition-related charges and balances, technology and product development costs, certain gains and losses from dispositions, and litigation settlements or other charges. Certain general and administrative costs such as human resources, information technology and training are allocated to the segments. Segment income from operations also excludes interest and other financial charges and income taxes. Corporate and other assets are comprised principally of cash, deposits, property, plant and equipment, domestic deferred taxes, deferred charges and other assets. Corporate loss from operations consists of depreciation on the corporate office facilities and equipment, administrative charges related to corporate personnel and other charges that cannot be readily identified for allocation to a particular segment.

Overview
 
We offer our customers “one source for asset protection solutions”® and are a leading global provider of technology-enabled asset protection solutions used to evaluate the structural integrity and reliability of critical energy, industrial and public infrastructure. We combine industry-leading products and technologies, expertise in mechanical integrity (MI), Non-Destructive Testing (NDT), Destructive Testing (DT) and predictive maintenance (PdM) services, process and fixed asset engineering and consulting services, proprietary data analysis and our world class enterprise inspection database management and analysis software, PCMS, to deliver a comprehensive portfolio of customized solutions, ranging from routine inspections to complex, plant-wide asset integrity management and assessments. These mission critical solutions enhance our customers’ ability to comply with governmental safety and environmental regulations, extend the useful life of their assets, increase productivity, minimize repair costs, manage risk and avoid catastrophic disasters. Our operations consist of three reportable segments: Services, International and Products and Systems.
 
Services provides asset protection solutions predominantly in North America with the largest concentration in the United States along with a growing Canadian services business, consisting primarily of NDT, inspection and engineering services that are used to evaluate the structural integrity and reliability of critical energy, industrial and public infrastructure.

International offers services, products and systems similar to those of the other segments to global markets, principally in Europe, the Middle East, Africa, Asia and South America, but not to customers in China and South Korea, which are served by the Products and Systems segment.

Given the role our solutions play in ensuring the safe and efficient operation of infrastructure, we have historically providedprovide a majority of our services to our customers on a regular, recurring basis. We serve a global customer base of companies with asset-intensive infrastructure, including companies in the oil and gas (downstream, midstream, upstream and petrochemical), power generation (natural gas, fossil, nuclear, alternative, renewable, and transmission and distribution), public infrastructure, chemicals, commercial aerospace and defense, transportation, primary metals and metalworking, pharmaceutical/biotechnology and food processing industries and research and engineering institutions. We have established long-term relationships as a critical solutions provider to many of the leading companies in our target markets.

For the last several years, we have focused on introducing our advanced asset protection solutions to our customers using proprietary, technology-enabled software and testing instruments, including those developed by our Products and Systems segment. During this period, the demand for outsourced asset protection solutions, in general, has increased, creating demand from which our entire industry has benefited. We believe continued growth can be realized in all of our target markets. Concurrent with this growth, we are working on building our infrastructure to profitably absorb additional growth and have made a number of acquisitions in an effort to leverage our fixed costs, grow our base of experienced, certified personnel, expand our product and technical capabilities and increase our geographical reach.
 
We have increased our capabilities and the size of our customer base through the development of applied technologies and managed support services, organic growth and the integration of acquired companies. These acquisitions have provided us with additional products, technologies, resources and customers that we believe will enhance our advantages over our competition.
 
The global economy continues to be fragile. Global financial markets continue to experience uncertainty, including tight liquidity and credit availability, relatively low consumer confidence, high unemployment rates, slow economic growth, fluctuating oil prices, which are currently very low, and volatile currency exchange rates. However, we believe these conditions have allowed us to selectively hire new talented individuals that otherwise might not have been available to us, to acquire new technologies in order to aggressively expand our proprietary portfolio of customized solutions, and to make acquisitions of complementary businesses at reasonable valuations.

Note About Non-GAAP Measures
 
Adjusted EBITDA is a performance measure used by management that is not calculated in accordance with U.S. generally accepted accounting principles (GAAP). EBITDA is defined in this Report as net income attributable to Mistras Group, Inc. plus: interest expense, provision for income taxes and depreciation and amortization. Adjusted EBITDA is defined in this Report as net income attributable to Mistras Group, Inc. plus: interest expense, provision for income taxes, depreciation and amortization, share-based compensation expense, and certain acquisition-related costs (including transaction due diligence costs and adjustments to the fair value of contingent consideration), foreign exchange loss and, if applicable, certain non-recurring items which we note.
 
Our managementManagement uses Adjusted EBITDA as a measure of operating performance to assist in comparing performance from period to period on a consistent basis, as a measure for planning and forecasting overall expectations and for evaluating actual results against such expectations. Adjusted EBITDA is also used as the basis for a performance evaluation metric for our executive and employee incentive compensation programs.

Later inIn the MD&A under the heading "Income forfrom Operations", the non-GAAP financial performance measures "Income from operations before acquisition-related expense (benefit), net” is used for each of our three segments and the "Total Company", with tables reconciling the measure to a financial measure under GAAP. This non-GAAP measures excludes from the GAAP measure "Income from Operations" (a) transaction expenses related to acquisitions, such as professional fees and due diligence costs and (b) the net changes in the fair value of acquisition-related contingent consideration liabilities. These items have been excluded from the GAAP measure because these expenses and credits are not related to the Company’s or Segment’s core business operations and are related solely to the Company’s or Segment’s acquisition activities. Changes in the fair value of acquisition-related contingent consideration liabilities can be a net expense or credit in any given period, and fluctuate based upon the then current value of cash consideration the Company expects to pay in the future for prior acquisitions, without impacting cash generated from the Company’s business operations.

In the MD&A section "Liquidity and Capital Resources", we use the term free cash flow, a non-GAAP measurement. We define free cash flow as cash provided by operating activities less capital expenditures (which is classified as an investing activity). Free cash flow for the first nine months of fiscal 20152016 was $22.5$43.5 million consisting of $34.3$55.8 million of operating cash flow less $11.8$12.3 million of capital expenditures. For the comparable period in fiscal 2014,2015, free cash flow was $10.9$22.2 million consisting of $22.6$34.5 million of operating cash flow less $11.7$12.3 million of capital expenditures.
 
We believe investors and other usersRevenue
Revenues for the three months ended February 29, 2016 were $160.4 million, a decrease of our financial statements benefit from$2.7 million, or 1.7%, compared to the presentationprior year. Revenues for the nine months ended February 29, 2016 were $535.0 million, a decrease of EBITDA, Adjusted EBITDA and "Income from operations before acquisition-related expense (benefit)$1.6 million, or 0.3%, net” for each of our three segments andcompared to the "Total Company", and free cash flow in evaluating our operating performance because they provide additional tools to compare our operating performance on a consistent basis and measure underlying trends and results in our business. EBITDA and Adjusted EBITDA remove the impact of certain items that management believes do not directly reflect our core operations. For instance, Adjusted EBITDA generally excludes interest expense, taxes and depreciation and amortization, each of which can vary substantially from company to company depending upon accounting methods and the book value and age of assets, capital structure, capital investment cycles and the method by which assets were acquired. It also eliminates share-basednine months ended February 28, 2015.

compensation, which is a non-cash expense and is excluded by management when evaluating the underlying performance of our business operations. Similarly, we believe that "Income from operations before acquisition-related expense (benefit), net” for each of our three segments and the "Total Company", provides investors with useful information and more meaningful period over period comparisons by identifying and excluding these acquisition-related costs so that the performance of the core business operations can be identified and compared.
While Adjusted EBITDA is a term and financial measurement commonly used by investors and securities analysts, it has limitations. As a non-GAAP measurement, Adjusted EBITDA has no standard meaning and, therefore, may not be comparable with similar measurements for other companies. Adjusted EBITDA is generally limited as an analytical tool because it excludes charges and expenses we do incur as part of our operations. For example, Adjusted EBITDA excludes income taxes, but we generally incur significant U.S. federal, state and foreign income taxes each year and the provision for income taxes is a necessary cost. EBITDA and Adjusted EBITDA should not be considered in isolation or as a substitute for analyzing our results as reported under U.S. generally accepted accounting principles. In addition, acquisitions are a part of our growth strategy, and therefore acquisition-related items are a necessary cost of the Company’s business. "Income from operations before acquisition-related expense (benefit), net” for each of our three segments and for the consolidated company and “free cash flow” are not metrics used to determine incentive compensation for executives or employees.
Revenue
Revenues were $163.1 million for the three months ended February 28, 2015 compared to $151.7 million for the three months ended February 28, 2014. Revenues were $536.6 million for the nine months ended February 28, 2015 compared to $444.3 million for the nine months ended February 28, 2014.
