Organization and Basis of Presentation [Abstract]
Organization and Basis of Presentation	1. Organization and Basis of Presentation Ecology and Environment, Inc., (“EEI”) was incorporated in 1970 as a global broad-based environmental consulting firm whose underlying philosophy is to provide professional services worldwide so that sustainable economic and human development may proceed with acceptable impact on the environment. Together with its subsidiaries (collectively, the “Company”), EEI has direct and indirect ownership in 7 active wholly owned and majority owned operating subsidiaries in 5 countries. The Company’s staff is comprised of individuals representing more than 80 scientific, engineering, health, and social disciplines working together in multidisciplinary teams to provide innovative environmental solutions. The Company has completed more than 50,000 projects for a wide variety of clients in more than 120 countries, providing environmental solutions in nearly every ecosystem on the planet. The Company prepared the condensed consolidated financial statements included herein, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of such information. All such adjustments are of a normal recurring nature. The Company reclassified certain prior year amounts to conform to the condensed consolidated financial statement presentation for the three and six months ended January 28, 2017. Although the Company believes that the disclosures are adequate to make the information presented not misleading, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), including a description of significant accounting policies, have been condensed or omitted pursuant to SEC rules and regulations. Therefore, these financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2016 filed with the Securities and Exchange Commission (the “2016 Annual Report”). The accounting policies followed by the Company for preparation of the consolidated financial statements included in the 2016 Annual Report were also followed for this interim report. The condensed consolidated results of operations for the three and six months ended January 28, 2017 are not necessarily indicative of the results for any subsequent period or the entire fiscal year ending July 31, 2017.

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	2. Recent Accounting Pronouncements Accounting Pronouncements Adopted During the Six Months Ended January 28, 2017 In September 2015, FASB issued ASU No. 2015-16, Business Combinations (Topic 805) – Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”). ASU 2015-16 requires an acquirer to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. In addition, the amendments in ASU 2015-16 require an acquirer to 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 amendments in ASU 2015-16 also require an entity to present separately on the face of the income statement, or disclose in the notes to the financial statements, 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 at the acquisition date. The amendments in ASU 2015-16 are effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years, and are to be applied prospectively to adjustments to provisional amounts that occur after the effective date. The Company adopted the provisions of ASU 2015-16 effective August 1, 2016. Management does not expect adoption of this standard to have a material impact on the Company’s consolidated financial statements. In May 2015, FASB issued ASU No. 2015-07, Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities that Calculate Net Asset Value Per Share (Or its Equivalent) (“ASU 2015-07”). ASU 2015-07 removes the requirements to: 1) categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value (“NAV”) per share practical expedient; and 2) make certain disclosures for all investments that are eligible to be measured at fair value using the NAV per share practical expedient. The amendments in ASU 2015-07 are effective for public entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The amendment must be applied retrospectively. The Company adopted ASU 2015-07 effective August 1, 2016. Other than the changes to disclosures noted above, adoption of this standard did not have a material impact on the Company’s consolidated financial statements. Refer to Note 4 of these condensed consolidated financial statements for additional disclosures regarding the Company’s investments in available for sale securities that are valued using the NAV practical expedient. In August 2014, FASB issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40) (“ASU 2014-15”). ASU 2014-15 requires an entity’s management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable). ASU 2014-15 provides guidance for management’s evaluation, including guidance regarding when substantial doubt about an entity’s ability to continue as a going concern exists, and when such doubt may be alleviated by management’s plans that are intended to mitigate those relevant conditions or events. ASU 2014-15 also provides guidance regarding appropriate financial statement disclosures regarding conditions or events that raised substantial doubt about the entity’s ability to continue as a going concern, management’s evaluation of the significance of those conditions or events in relation to the entity’s ability to meet its obligations, and management’s plans that are intended to mitigate those conditions or events. The provisions of ASU 2014-15 are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Earlier application is permitted. The Company adopted ASU 2014-15 effective August 1, 2016. Management does not expect the adoption of this standard to have a material impact on the Company’s consolidated financial statements. In November 2016, FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230) – Restricted Cash – a consensus of the FASB Emerging Issues Task Force (“ASU 2016-18”). The amendments included in this update require that amounts described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. For public entities, the amendments included in ASU 2016-18 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company adopted the provisions of ASU 2016-18 effective August 1, 2016. Adoption of this standard did not have a material impact on the Company’s consolidated financial statements. Refer to Note 3 of these condensed consolidated financial statements for additional disclosures regarding the Company’s cash, cash equivalents and restricted cash. Accounting Pronouncements Not Yet Adopted as of January 28, 2017 In March 2016, FASB issued ASU No. 2016-09, Compensation – Stock Compensation (Topic 718) – Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). The objective of ASU 2016-09 is to simplify several aspects of the accounting for 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. The amendments in ASU 2016-09 are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted in any interim or annual period, subject to transition requirements. The Company intends to adopt the provisions of ASU 2016-09 effective August 1, 2017. Management is currently assessing the provisions of ASU 2016-09 and has not yet estimated its impact on the Company’s consolidated financial statements. In May 2014, FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). ASU 2014-09 is the result of a joint project of FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for use in the U.S and internationally. ASU 2014-09 supersedes the revenue recognition requirements in Topic 605 of FASB’s Accounting Standards Codification (the “Codification”) and most industry-specific guidance throughout the Industry Topics of the Codification. ASU 2014-09 enhances comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets, reduces the number of requirements an entity must consider for recognizing revenue, and requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. ASU 2014-09 was to be effective for annual reporting periods beginning after December 15, 2016, including interim periods within the annual reporting period. In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606), Deferral of the Effective Date (“ASU 2015-14”). The amendments in ASU 2015-14 defer the effective date of ASU 2014-09 for all entities by one year. The Company intends to adopt the provisions of ASU 2014-09 effective August 1, 2018. During the fiscal years year ended July 31, 2017 and 2016, FASB issued six additional ASUs that provide clarification for specific aspects of ASU 2014-09. The effective dates and transition requirements for these ASUs are the same as the effective dates and transition requirements included in ASU 2014-09 and ASU 2015-14. ASU 2014-09 requires retrospective application by either restating each prior period presented in the financial statements, or by recording the cumulative effect on prior reporting periods to beginning retained earnings in the year that the standard becomes effective. Management is currently assessing the provisions of ASU 2014-09 and has not yet estimated its impact or selected a transition method. In January 2016, FASB issued ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10) – Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). The amendments included in this update make targeted improvements to U.S. GAAP. Entities are required to apply the amendments included in ASU 2016-01 by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. For public entities, the amendments included in ASU 2016-01 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company intends to adopt the provisions of ASU 2016-01 effective August 1, 2018. Management is currently assessing the provisions of ASU 2016-01 and has not yet estimated its impact on the Company’s consolidated financial statements. In August 2016, FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). The amendments included in this update provide guidance regarding eight specific cash flow classification issues that are not specifically addressed in previous U.S. GAAP. For public entities, the amendments included in ASU 2016-01 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company intends to adopt the provisions of ASU 2016-01 effective August 1, 2018. Management is currently assessing the provisions of ASU 2016-15 and has not yet estimated its impact on the Company’s consolidated financial statements. In January 2017, FASB issued ASU No. 2017-01, Business Combinations (Topic 805) – Clarifying the Definition of a Business (“ASU 2017-01”). The amendments included in this update clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisition, disposals, goodwill and consolidation. Public entities are required to adopt the amendments included in ASU 2017-01 effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company intends to adopt the provisions of ASU 2017-01 effective August 1, 2018. Adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In March 2016, FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 requires lessees to recognize the assets and liabilities that arise from most leases. The main difference between previous U.S. GAAP and ASU 2016-02 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous U.S. GAAP. For lessors, the guidance included in ASU 2016-02 modifies the classification criteria and the accounting for sales-type and direct financing leases. ASU 2016-02 provides specific guidance for determining whether a contractual arrangement contains a lease, lease classification by lessees and lessors, initial and subsequent measurement of leases by lessees and lessors, sale and leaseback transactions, transition, and financial statement disclosures. ASU 2016-02 requires entities to use a modified retrospective approach to apply its guidance, and includes a number of optional practical expedients that entities may elect to apply. For public entities, the amendments included in ASU 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company intends to adopt the provisions of ASU 2016-02 effective August 1, 2019. Early adoption of the amendments included in ASU 2016-02 is permitted.

Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	4. Fair Value of Financial Instruments The Company’s financial assets or liabilities are measured using inputs from the three levels of the fair value hierarchy. The Company classifies assets and liabilities within the fair value hierarchy based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. The Company has not elected a fair value option on any assets or liabilities. The three levels of the hierarchy are as follows: Level 1 Inputs Level 2 Inputs Level 3 Inputs The Company monitors the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the Company reports the transfer as of the beginning of the reporting period. The Company evaluated the significance of transfers between levels based upon the nature of the financial instrument. There were no transfers in or out of levels 1, 2 or 3, respectively during the six months ended January 28, 2017 or the fiscal year ended July 31, 2016. The carrying amount of cash, cash equivalents and restricted cash approximated fair value at January 28, 2017 and July 31, 2016. These assets were classified as level 1 instruments at both dates. Investment securities available for sale of $1.5 million at January 28, 2017 and July 31, 2016 primarily included mutual funds invested in U.S. municipal bonds, which the Company may immediately redeem without prior notice. These mutual funds are valued at the net asset value (“NAV”) of shares held by the Company at period end as a practical expedient to estimate fair value. These mutual funds are deemed to be actively traded, are required to publish their daily NAV and are required to transact at that price. As a result of t he Company’s adoption of ASU 2015-07 effective August 1, 2016 (refer to Note 2 above), investment securities available for sale are not reported within the fair value hierarchy noted above. Unrealized gains or losses related to investment securities available for sale are recorded in accumulated other comprehensive income, net of applicable income taxes in the accompanying condensed consolidated balance sheets and condensed consolidated statements of changes in shareholders' equity. The cost basis of securities sold is based on the specific identification method. The Company had unrealized gains of less than $0.1 million recorded in accumulated other comprehensive income during the six months ended January 28, 2017 and January 30, 2016. Reclassification adjustments out of accumulated other comprehensive income are included within gain on sale of assets on the accompanying condensed consolidated statements of operations. The Company did not record any sales of investment securities during the six months ended January 28, 2017 or January 30, 2016. Long-term debt consists of bank loans and capitalized equipment leases. Lines of credit consist of borrowings for working capital requirements. Based on the Company's assessment of the current financial market and corresponding risks associated with the debt and line of credit borrowings, management believes that the carrying amount of these liabilities approximated fair value at January 28, 2017 and July 31, 2016. These liabilities were classified as level 2 instruments at both dates. There were no financial instruments classified as level 3 at January 28, 2017 or July 31, 2016.

Revenue and Contract Receivables, net [Abstract]
Revenue and Contract Receivables, net	5. Revenue and Contract Receivables, net Revenue Recognition The Company derives substantially all of its revenue from environmental consulting work, principally from the sale of labor hours. The consulting work is performed under a mix of fixed price, cost-type, and time and material contracts. Contracts are required from all customers. The Company recognizes revenue as follows: Contract Type Work Type Revenue Recognition Policy Time and materials Consulting As incurred at contract rates. Fixed price Consulting Percentage of completion, approximating the ratio of either total costs or Level of Effort (LOE) hours incurred to date to total estimated costs or LOE hours. Cost-plus Consulting Costs as incurred plus fees. Fees are recognized as revenue using percentage of completion determined by the percentage of LOE hours incurred to total LOE hours in the respective contracts. Revenues represent services rendered by employees for which the Company maintains a primary contractual relationship with its customers, as well as certain services that the Company has elected to subcontract to others. The Company accounts for time and material contracts over the period of performance, in proportion to the costs of performance, predominately based on labor hours incurred. Revenue earned from fixed price and cost-plus contracts is recognized using the “percentage-of-completion” method, wherein revenue is recognized as project progress occurs. If an estimate of costs at completion on any contract indicates that the Company will incur a loss, the entire estimated loss is charged to operations in the period the loss becomes evident. Substantially all of the Company's cost-type work is with federal governmental agencies and, as such, is subject to audits after contract completion. Under these cost-type contracts, provisions for adjustments to accrued revenue are recognized on a quarterly basis and based on past audit settlement history. Government audits have been completed and final rates have been negotiated through fiscal year 2009. The Company records an allowance for project disallowances in other accrued liabilities for potential disallowances resulting from government audits (refer to Note 10 of these consolidated financial statements). Allowances for project disallowances are recorded when the amounts are estimable. Resolution of these amounts is dependent upon the results of government audits and other formal contract close-out procedures. Change orders can occur when changes in scope are made after project work has begun, and can be initiated by either the Company or its clients. Claims are amounts in excess of the agreed contract price which the Company seeks to recover from a client for customer delays and /or errors or unapproved change orders that are in dispute. The Company recognizes costs related to change orders and claims as incurred. Revenues and profit are recognized on change orders when it is probable that the change order will be approved and the amount can be reasonably estimated. Revenues are recognized only up to the amount of costs incurred on contract claims when realization is probable, estimable and reasonable support from the customer exists. The Company expenses all bid and proposal and other pre-contract costs as incurred. Out of pocket expenses such as travel, meals, field supplies, and other costs billed direct to contracts are included in both revenues and cost of professional services. Sales and cost of sales at the Company’s South American subsidiaries exclude tax assessments by governmental authorities, which the Company collects from its customers and remits to governmental authorities. Billed contract receivables represent amounts billed to clients in accordance with contracted terms but not collected as of the end of the reporting period. Billed contract receivables may include: (1) amounts billed for revenues from incurred costs and fees earned in accordance with contractual terms; and (2) progress billings in accordance with contractual terms that include revenue not yet earned as of the end of the reporting period. Unbilled contract receivables result from: (i) earned revenues from incurred costs not billed as of period-end; and (ii) differences between year-to-date provisional billings and year-to-date actual contract costs incurred. The Company reduces contract receivables by establishing an allowance for contract adjustments related to revenues that are deemed to be unrealizable, or that may become unrealizable in the future. The Company also reduces contract receivables by recording an Contract Receivables, Net Contract receivables, net are summarized in the following table. Balance at January 28, 2017 July 31, 2016 (in thousands) Contract Receivables: Billed $ 17,174 $ 20,415 Unbilled 16,228 20,696 33,402 41,111 Allowance for doubtful accounts and contract adjustments (2,047 ) (6,792 ) Total contract receivables, net $ 31,355 $ 34,319 Billed contract receivables included contractual retainage balances of $1.0 million and $0.9 million at January 28, 2017 and July 31, 2016, respectively. Management anticipates that the Company will substantially bill and collect the unbilled receivables and retainage balances outstanding at January 28, 2017 within one year. Contract Receivable Concentrations Significant concentrations of contract receivables and the allowance for doubtful accounts and contract adjustments are summarized in the following table. Balance at January 28, 2017 Balance at July 31, 2016 Region Contract Receivables Allowance for Doubtful Accounts and Contract Adjustments Contract Receivables Allowance for Doubtful Accounts and Contract Adjustments (in thousands) United States, Canada and South America $ 32,920 $ 2,047 $ 36,128 $ 1,897 Middle East and Africa 234 --- 4,922 4,895 Asia 248 --- 61 --- Totals $ 33,402 $ 2,047 $ 41,111 $ 6,792 During the three months ended January 28, 2017, the Company wrote-off $4.9 million of aged and fully reserved contract receivable balances related to a specific project in the Middle East, based on management’s assessment that cash collections are not likely. Prior to the write-off described above, combined contract receivables related to projects in the Middle East, Africa and Asia represented 12% of total contract receivables at July 31, 2016, while the combined allowance for doubtful accounts and contract adjustments related to these projects represented 72% of the total allowance for doubtful accounts and contract adjustments at July 31, 2016. This allowance percentage reflects the Company’s experience of heightened operating risks (i.e., political, regulatory and cultural risks) within these foreign regions in comparison with similar risks in the United States, Canada and South America, which result in increased collection risks and the risk of the Company expending resources that it may not recover for several months, or at all. Allowance for Doubtful Accounts and Contract Adjustments Activity within the allowance for doubtful accounts and contract adjustments is summarized in the following table.

Stock Award Plan	11 . Stock Award Plan EEI adopted the 1998 Stock Award Plan effective March 16, 1998. This plan, together with supplemental plans that were subsequently adopted by the Company’s Board of Directors, is referred to as the “Stock Award Plan.” The Stock Award Plan is not a qualified plan under Section 401(a) of the Internal Revenue Code. Under the Stock Award Plan, Directors, officers and other key employees of EEI or any of its subsidiaries may be awarded Class A Common Stock as a bonus for services rendered to the Company or its subsidiaries, based upon the fair market value of the common stock at the time of the award. The Stock Award Plan authorizes the Company’s Board of Directors to determine the vesting period and the circumstances under which the awards may be forfeited. Under the supplemental plan in place as of July 31, 2016, which expired in October 2016, the Company issued 17,386 shares of Class A Common Stock under the Stock Award Plan, all of which were fully vested at July 31, 2016. In October 2016, the Company’s Board of Directors adopted the current supplemental plan (the “2016 Stock Award Plan”). The 2016 Stock Award Plan permits awards of up to 200,000 shares of Class A Common Stock for a period of up to five years until its termination in October 2021. As of January 28, 2017, there have not been any stock awards granted under the 2016 Stock Award Plan. EEI recorded non-cash compensation expense of $0 and less than $0.1 million during the six months ended January 28, 2017 and January 30, 2016, respectively.

Shareholders' Equity [Abstract]
Shareholders' Equity	12. Shareholders' Equity Class A and Class B Common Stock The relative rights, preferences and limitations of the Company's Class A and Class B Common Stock are summarized as follows: Holders of Class A shares are entitled to elect 25% of the Board of Directors so long as the number of outstanding Class A shares is at least 10% of the combined total number of outstanding Class A and Class B common shares. Holders of Class A common shares have one-tenth the voting power of Class B common shares with respect to most other matters. In addition, Class A shares are eligible to receive dividends in excess of (and not less than) those paid to holders of Class B shares. Holders of Class B shares have the option to convert at any time, each share of Class B Common Stock into one share of Class A Common Stock. Upon sale or transfer, shares of Class B Common Stock will automatically convert into an equal number of shares of Class A Common Stock, except that sales or transfers of Class B Common Stock to an existing holder of Class B Common Stock or to an immediate family member will not cause such shares to automatically convert into Class A Common Stock. Restrictive Shareholder Agreement Messrs. Gerhard J. Neumaier (deceased), Frank B. Silvestro, Ronald L. Frank, and Gerald A. Strobel (the “Signatories”) entered into a Stockholders’ Agreement dated May 12, 1970, as amended January 24, 2011 (the “Stockholders’ Agreement”). The Stockholders’ Agreement governs the sale of certain shares of Ecology and Environment, Inc. common stock (now classified as Class B Common Stock) owned by the Signatories, certain children of those individuals and any such shares subsequently transferred to their spouses and/or children outright or in trust for their benefit upon the demise of a Signatory to the Stockholders’ Agreement (“Permitted Transferees”). The Stockholders’ Agreement provides that prior to accepting a bona fide offer to purchase some or all of their shares of Class B Common Stock governed by the Stockholders’ Agreement, that the selling party must first allow the other Signatories (not including any Permitted Transferee, as defined in the Stockholders’ Agreement) the opportunity to acquire on a pro rata basis, with right of over-allotment, all of such shares covered by the offer on the same terms and conditions proposed by the offer. Cash Dividends The Company declared and accrued $0.9 million and $1.0 million of cash dividends during the six months ended January 28, 2017 and January 30, 2016, respectively, which were paid in February 2017 and 2016, respectively. The Company paid dividends of $0.9 million and $1.0 million in August 2016 and 2015, respectively, that were declared and accrued in prior periods. Stock Repurchase Plan In August 2010, the Company’s Board of Directors approved a program for repurchase of 200,000 shares of Class A common stock (the “Stock Repurchase Program”). As of January 28, 2017, the Company repurchased 122,918 shares of Class A stock, and 77,082 shares had yet to be repurchased under the Stock Repurchase Program. The Company did not acquire any Class A shares under the Stock Repurchase Program during the six months ended January 28, 2017 or January 30, 2016. Noncontrolling Interests The Company discloses noncontrolling interests as a separate component of consolidated shareholders’ equity on the accompanying consolidated balance sheets. Earnings and other comprehensive income (loss) are separately attributed to both the controlling and noncontrolling interests. The Company calculates EPS based on net income (loss) attributable to the Company’s controlling interests. The Company considers acquiring additional interests in majority owned subsidiaries when noncontrolling shareholders express their intent to sell their interests. The Company settles and records acquisitions of noncontrolling interests at amounts that approximate fair value. Purchases of noncontrolling interests are recorded as reductions of shareholders’ equity on the condensed consolidated statements of shareholders’ equity. The Company did not acquire additional interest in any of its majority-owned subsidiaries during the six months ended January 28, 2017 or January 30, 2016.

Earnings Per Share [Abstract]
Earnings Per Share	13. Earnings Per Share The Company calculates basic and diluted EPS by dividing the net income (loss) attributable to Ecology and Environment, Inc. common shareholders by the weighted average number of common shares outstanding for the period. After consideration of all the rights and privileges of the Class A and Class B stockholders summarized in Note 12, in particular the right of the holders of the Class B common stock to elect no less than 75% of the Board of Directors making it highly unlikely that the Company will pay a dividend on Class A common stock in excess of Class B common stock, the Company allocates undistributed earnings between the two classes of stock on a one-to-one basis when computing earnings per share. As a result, basic and fully diluted earnings per Class A and Class B share are equal amounts. The Company has determined that its unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities. These securities shall be included in the computation of earnings per share pursuant to the two-class method. The resulting impact was to include unvested restricted shares in the weighted average shares outstanding calculation. The computation of earnings per share is included in the following table.

On February 4, 2011, the Chico Mendes Institute of Biodiversity Conservation of Brazil (the “Institute”) issued a Notice of Infraction to ecology and environment do brasil Ltda (“E&E Brasil”), a majority-owned subsidiary of EEI. The Notice of Infraction concerned the taking and collecting wild animal specimens without authorization by the competent authority and imposed a fine of 520,000 Reais against E&E Brazil. The Institute also filed Notices of Infraction against four employees of E&E Brasil alleging the same claims and imposed fines against those individuals that, in the aggregate, were equal to the fine imposed against E&E Brasil. The Institute has not filed any claim against EEI. E&E Brasil has filed court claims appealing the administrative decisions of the Institute for E & E Brasil’s employees that: (a) deny the jurisdiction of the Institute; (b) state that the Notice of Infraction is constitutionally vague; and (c) affirmatively state that E&E Brasil had obtained the necessary permits for the surveys and collections of specimens under applicable Brazilian regulations and that the protected conservation area is not clearly marked to show its boundaries. The claim of violations against one of the four employees was dismissed. The remaining three employees have fines assessed against them that are being appealed through the federal courts. Violations against E&E Brasil are pending agency determination. At January 28, 2017, the Company maintained a reserve of approximately $0.3 million in other accrued liabilities related to these claims. Contract Termination Provisions Certain contracts contain termination provisions under which the customer may, without penalty, terminate the contracts upon written notice to the Company. In the event of termination, the Company would be paid only termination costs in accordance with the particular contract. Generally, termination costs include unpaid costs incurred to date, earned fees and any additional costs directly allocable to the termination. The Company did not experience early termination of any material contracts during the six months ended January 28, 2017 or during the fiscal year ended July 31, 2016.
