Accounting Policies [Abstract]  
Revenue Recognition
Revenue Recognition:    The Company recognizes contract revenue in accordance with Accounting Standards Codification ("ASC") Topic 605, Revenue Recognition ("ASC Topic 605"). Specifically, the Company follows the guidance in ASC Subtopic 605-35, Revenue Recognition—Construction-Type and Production-Type Contracts.
Fixed-Price Contracts
The Company recognizes revenue on fixed-price contracts using the percentage-of-completion method. Under this method of revenue recognition, the Company estimates the progress towards completion to determine the amount of revenue and profit to recognize on all significant contracts. The Company generally utilizes an efforts-expended, cost-to-cost approach in applying the percentage-of-completion method under which revenue is earned in proportion to total costs incurred divided by total costs expected to be incurred.
Under the percentage-of-completion method, recognition of profit is dependent upon the accuracy of a variety of estimates including engineering progress, materials quantities, achievement of milestones and other incentives, liquidated-damages provisions, labor productivity and cost estimates. Such estimates are based on various judgments the Company makes with respect to those factors and can be difficult to accurately determine until the project is significantly underway. Due to uncertainties inherent in the estimation process, actual completion costs often vary from estimates. If estimated total costs on any contract indicate a loss, the Company charges the entire estimated loss to operations in the period the loss first becomes known. If actual costs exceed the original fixed contract price, recognition of any additional revenue will be pursuant to a change order, contract modification, or claim.
The Company has entered into fixed-price Exit Strategy contracts to remediate environmental conditions at contaminated sites. Under most Exit Strategy contracts, the majority of the contract price was deposited by the client into a restricted account with an insurer. The funds in the restricted account are held by the insurer and used to pay the Company as work is performed. The arrangement with the insurer provides for the deposited funds to earn interest at the one-year constant maturity U.S. Treasury Bill rate. The interest is recorded when earned and reported as interest income from contractual arrangements on the Company's consolidated statements of operations. On certain Exit Strategy projects the Company has taken title to the underlying properties in order to facilitate access, remedial construction, performance of operations monitoring and maintenance activities and the overall execution of the cleanup. As these properties are distressed, they have no value.
The Exit Strategy funds held by the insurer, including any interest earned thereon, are recorded as an asset (current and long-term restricted investment) on the Company's consolidated balance sheets, with a corresponding liability (current and long-term deferred revenue) related to the funds. Consistent with the Company's other fixed-price contracts, the Company recognizes revenue on Exit Strategy contracts using the percentage-of-completion method. When determining the extent of progress towards completion on Exit Strategy contracts, prepaid insurance premiums and fees are amortized, on a straight-line basis, to cost incurred over the life of the related insurance policy. Certain Exit Strategy contracts were classified as pertaining to either remediation or operation, maintenance and monitoring. In addition, certain Exit Strategy contracts were segmented such that the remediation and operation portion of the contract is separately accounted for from the maintenance and monitoring portion.
Under most Exit Strategy contracts, additional payments were made by the client to the insurer, typically through an insurance broker, for insurance premiums and fees for a policy to cover potential costs in excess of the original estimates and other factors such as third party liability. For Exit Strategy contracts where the Company establishes that (1) costs exceed the contract value and interest growth thereon and (2) such costs are covered by insurance, the Company will record an estimated insurance recovery up to the amount of insured costs. An insurance gain, that is, an amount to be recovered in excess of the Company's recorded costs, is not recognized until the receipt of insurance proceeds. Insurance recoveries are reported as insurance recoverables and other income on the Company's consolidated statements of operations. If estimated total costs on any contract indicate a loss, the Company charges the entire estimated loss to operations in the period the loss first becomes known.
Unit price contracts are a subset of fixed-price contracts. Under unit price contracts, the Company's clients pay a set fee for each unit of service or production. The Company recognizes revenue under unit price contracts as it completes the related service transaction for its clients. If the Company's costs per service transaction exceed original estimates, its profit margins will decrease, and it may realize a loss on the project unless it can receive payment for the additional costs.
Time-and-Materials Contracts
Under time-and-materials contracts the Company negotiates hourly billing rates and charges its clients based on the actual time that it expends on a project. In addition, clients reimburse the Company for actual out-of-pocket costs of materials and other direct reimbursable expenses that it incurs in connection with its performance under the contract. The Company's profit margins on time-and-materials contracts fluctuate based on actual labor and overhead costs that it directly charges or allocates to contracts compared to negotiated billing rates. Revenue on time-and-materials contracts is recognized based on the actual number of hours the Company spends on the projects plus any actual out-of-pocket costs of materials and other direct reimbursable expenses that it incurs on the projects.
Cost-Plus Contracts
Cost-Plus Fixed Fee Contracts.   Under the Company's cost-plus fixed fee contracts it charges clients for its costs, including both direct and indirect costs, plus a fixed negotiated fee. In negotiating a cost-plus fixed fee contract the Company estimates all recoverable direct and indirect costs and then adds a fixed profit component. The total estimated cost plus the negotiated fee represents the total contract value. The Company recognizes revenue based on the actual labor and non-labor costs it incurs plus the portion of the fixed fee it has earned to date.
Cost-Plus Fixed Rate Contracts.   Under the Company's cost-plus fixed rate contracts it charges clients for its costs plus negotiated rates based on its indirect costs. In negotiating a cost-plus fixed rate contract the Company estimates all recoverable direct and indirect costs and then adds a profit component, which is a percentage of total recoverable costs, to arrive at a total dollar estimate for the project. The Company recognizes revenue based on the actual total costs it has expended plus the applicable fixed rate. If the actual total costs are lower than the total costs the Company has estimated, its revenue from that project will be lower than originally estimated.
Change Orders/Claims
Change orders are modifications to an original contract that change the provisions of the contract. Change orders typically result from changes in scope, specifications or design, manner of performance, facilities, equipment, materials, sites, or period of completion of the work. Claims are amounts in excess of the agreed contract price that the Company seeks to collect from its clients or others for client-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes.
Costs related to change orders and claims are recognized when they are incurred. Change orders are included in total estimated contract revenue when it is probable that the change order will result in a bona fide addition to contract value and can be reliably estimated. Claims are included in total estimated contract revenues only to the extent that contract costs related to the claims have been incurred and when it is probable that the claim will result in a bona fide addition to contract value which can be reliably estimated. No profit is recognized on claims until final settlement occurs. For the fiscal years ended June 30, 2013, 2012 and 2011, no revenue related to claims was recognized by the Company.
Other Contract Matters
Federal Acquisition Regulations ("FAR"), which are applicable to the Company's federal government contracts and may be incorporated in many local and state agency contracts, limit the recovery of certain specified indirect costs on contracts. Cost-plus contracts covered by FAR or with certain state and local agencies also require an audit of actual costs and provide for upward or downward adjustments if actual recoverable costs differ from billed recoverable costs. Most of the Company's federal government contracts are subject to termination at the discretion of the client. Contracts typically provide for reimbursement of costs incurred and payment of fees earned through the date of such termination.
Contracts with the federal government are subject to audit, primarily by the Defense Contract Audit Agency ("DCAA"), which reviews the Company's overhead rates, operating systems and cost proposals. During the course of its audits, the DCAA may disallow costs if it determines that the Company has accounted for such costs in a manner inconsistent with Cost Accounting Standards or FAR. The Company's last incurred cost audit was for fiscal year 2004 and resulted in an immaterial adjustment. DCAA determined that an audit of incurred cost proposals submitted to DCAA for fiscal years 2005 through 2008 was not required.  Incurred cost proposals have been submitted to DCAA for fiscal years 2009 through 2012 and are pending DCAA audit. Historically the Company has not had any material cost disallowances by the DCAA as a result of audit, however there can be no assurance that DCAA audits will not result in material cost disallowances in the future.
Allowance for Doubtful Accounts Allowance for Doubtful Accounts—An allowance for doubtful accounts is maintained for estimated losses resulting from the failure of the Company's clients to make required payments. The allowance for doubtful accounts has been determined through reviews of specific amounts deemed to be uncollectible and estimated write-offs as a result of clients who have filed for bankruptcy protection plus an allowance for other amounts for which some loss is determined to be probable based on current circumstances. If the financial condition of clients or the Company's assessment as to collectability were to change, adjustments to the allowances may be required.
Stock-Based Compensation
Stock-Based Compensation—The Company accounts for stock-based awards in accordance with ASC Topic 718, Compensation—Stock Compensation ("ASC Topic 718"), which requires the measurement and recognition of compensation expense for all stock-based awards made to the Company's employees and directors including stock options, restricted stock, and other stock-based awards based on estimated fair values.
The Company measures stock-based compensation cost at the grant date based on the fair value of the award. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in the Company's consolidated statements of operations. Stock-based compensation expense includes the estimated effects of forfeitures, and estimates of forfeitures will be adjusted over the requisite service period to the extent actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized in the period of change and will also impact the amount of expense to be recognized in future periods.
The Company uses the Black-Scholes option pricing model for determining the estimated grant date fair value for stock options. The fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. The risk-free interest rate assumption is based upon observed interest rates appropriate for the expected life of the employee stock options. The average expected life is based on the contractual term of the option and expected employee exercise and historical post-vesting employment termination experience. The Company estimates the volatility of its stock using historical volatility in accordance with current accounting guidance. Management determined that historical volatility of TRC common stock is most reflective of market conditions and the best indicator of expected volatility. The dividend yield assumption is based on the Company's historical and expected dividend payouts. The assumptions used to value stock options granted for fiscal years 2013, 2012 and 2011 are as follows:

Income Taxes
Income Taxes—The Company is required to estimate the provision for income taxes, including the current tax expense together with an assessment of temporary differences resulting from differing treatments of assets and liabilities for tax and financial accounting purposes. These differences between the financial statement and tax bases of assets and liabilities, together with net operating loss ("NOL") carryforwards and tax credits are recorded as deferred tax assets or liabilities on the consolidated balance sheets. An assessment is required to be made of the likelihood that the deferred tax assets will be recovered from future taxable income. To the extent that the Company determines that it is more likely than not that the deferred asset will not be utilized, a valuation allowance is established. Taxable income in future periods significantly above or below that projected will cause adjustments to the valuation allowance that could materially decrease or increase future income tax expense.
During the fourth quarter of fiscal 2013, the Company concluded it was more likely than not that its deferred tax assets will be realized and reversed our valuation allowance in the amount of $25,646 (see Note 12).
The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Accounting literature also provides guidance on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, and income tax disclosures. Judgment is required in assessing the future tax consequences of events that have been recognized in the Company's financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact the Company's financial statements.
Goodwill and Other Intangible Assets
Goodwill and Other Intangible Assets—In accordance with ASC Topic 350, Intangibles—Goodwill and Other, goodwill and intangible assets deemed to have indefinite lives are not amortized but are subject to impairment testing at least annually, or more frequently if events or changes in circumstances indicate that goodwill might be impaired. The Company performs impairment tests for its reporting units with recorded goodwill utilizing valuation methods, including the discounted cash flow method, the guideline company approach, and the guideline transaction approach, as the best evidence of fair value. The valuation methodology used to estimate the fair value of the total Company and its reporting units requires inputs and assumptions (i.e. revenue growth, operating profit margins and discount rates) that reflect current market conditions. The estimated fair value of each reporting unit is compared to the carrying amount of the reporting unit, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the goodwill of the reporting unit is potentially impaired, and the Company then determines the implied fair value of goodwill, which is compared to the carrying value of goodwill to determine if impairment exists.
The Company performed its most recent annual goodwill impairment review as of April 26, 2013, and noted the fair value of each of the Company's reporting units with goodwill exceeded its carrying value. Therefore no further analysis was required. As of June 30, 2013, the Company had $28,797 of goodwill. The Company does not believe there were any events or changes in circumstances since its April 2013 annual assessment that would indicate the fair value of goodwill was more likely than not reduced to below its carrying value. In making this assessment, the Company relied on a number of factors including operating results, business plans, anticipated future cash flows, transactions and market data.
Other intangible assets are included in other assets on the consolidated balance sheets and consist primarily of purchased customer relationships and other intangible assets acquired in acquisitions. The costs of intangible assets with determinable useful lives are amortized on a basis approximating the economic value derived from those assets. The Company reviews the economic lives of its intangible assets annually.
Management judgment and assumptions are required in performing the impairment tests for all reporting units with goodwill and in measuring the fair value of goodwill, indefinite-lived intangibles and long-lived assets. While the Company believes its judgments and assumptions are reasonable, different assumptions could change the estimated fair values or the amount of recognized impairment losses.
Preferred Stock
Preferred Stock—The Company applies the guidance in ASC Topic 480, Distinguishing Liabilities from Equity ("ASC Topic 48"), and Accounting Standards Update ("ASU") 2009-04, Accounting for Redeemable Equity Instruments ("ASU 2009-04"), when determining the classification and measurement of preferred stock. Preferred shares subject to mandatory redemption are classified as liability instruments and are measured at fair value in accordance with ASC Topic 480. The Company does not have any preferred shares subject to mandatory redemption. Preferred shares not subject to ASC Topic 480 are subject to the classification and measurement principles of ASU 2009-04. In accordance with ASU 2009-04, the Company classified its convertible preferred stock, which was subject to redemption upon the occurrence of a liquidation or sale, events not solely within the Company's control, as temporary equity. Because a liquidation or sale was not probable as of June 30, 2010, an adjustment from the preferred stock's carrying amount to the redemption amount was not required. The preferred stock converted to common stock on December 1, 2010 and therefore as of June 30, 2011 was not subject to the classification and measurement principles of ASU 2009-04.
Property and Equipment
Property and Equipment—Property and equipment are recorded at cost, including costs to bring the equipment into operation. Major improvements to and betterments that extend the useful life of existing equipment are capitalized. Maintenance and repairs are charged to expense as incurred. The Company provides for depreciation of property and equipment using the straight-line method over estimated useful lives of the assets as follows:
Asset Category
 
Estimated Useful Life
Building
 
30 years
Equipment, furniture and fixtures
 
3 - 10 years
Leasehold improvements and assets under capital leases
 
Lesser of the estimated useful life or the term of the lease

 
 
 

In accordance with ASC Topic 360, Property, Plant and Equipment, the Company periodically evaluates whether events or circumstances have occurred that indicate that long-lived assets may not be recoverable or that the remaining useful life may warrant revision. There were no events or changes in circumstances that would indicate the fair value of property and equipment was reduced to below its carrying value during fiscal year 2013, and therefore property and equipment were not tested for impairment. When such events or circumstances are present, the Company assesses the recoverability of long-lived assets by determining whether the carrying value will be recovered through the expected undiscounted future cash flows resulting from the use of the asset. In the event the sum of the expected undiscounted future cash flows is less than the carrying value of the asset, an impairment loss equal to the excess of the asset's carrying value over its fair value is recorded. The long-term nature of these assets requires the estimation of cash inflows and outflows several years into the future.
Consolidation
Consolidation—The consolidated financial statements include the Company and its wholly-owned subsidiaries after elimination of intercompany accounts and transactions. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity ("VIE") under generally accepted accounting principles.
Variable Interest Entity
Voting Interest Entities.  Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and which provide the equity holders with the obligation to absorb losses, the right to receive residual returns and the right or power to make decisions about or direct the entity's activities that most significantly impact the entity's economic performance. Voting interest entities, where the Company has a majority interest, are consolidated in accordance with ASC Topic 810, Consolidations (“ASC Topic 810”). ASC Topic 810 states that the usual condition for a controlling financial interest in an entity is ownership of a majority voting interest. Accordingly, the Company consolidates voting interest entities in which it has all, or a majority of, the voting interests.
Variable Interest Entities ("VIE's").  VIE's are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when an enterprise has a variable interest, or a combination of variable interests, that will absorb a majority of the VIE's expected losses, receive a majority of the VIE's expected residual returns, or both. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE. In accordance with ASC Topic 810, the Company consolidates the CAH VIE because it is the primary beneficiary.
The Company determines whether it is the primary beneficiary of a VIE by performing a qualitative analysis of the VIE that includes, among other factors, a review of its capital structure, contractual terms, which interests create or absorb variability, related party relationships and the design of the VIE.
Equity Method Investments
Equity-Method Investments.  When the Company does not have a controlling financial interest in an entity but exerts significant influence over the entity's operating and financial policies (generally defined as owning a voting interest of 20% to 50% for a corporation or 3% to 50% for a partnership or Limited Liability Company) and has an investment in common stock or in-substance common stock, the Company accounts for its investment in accordance with the equity method of accounting prescribed by ASC Topic 323, Investments—Equity Method and Joint Ventures.
Insurance Matters, Litigation and Contingencies
Insurance Matters, Litigation and Contingencies—In the normal course of business the Company is subject to certain contractual guarantees and litigation. Generally such guarantees relate to project schedules and performance. Most of the litigation involves the Company as a defendant in contractual disputes, professional liability, personal injury and other similar lawsuits. The Company maintains insurance coverage for various aspects of its business and operations, however the Company has elected to retain a portion of losses that may occur through the use of substantial deductibles, exclusions and retentions under our insurance programs. This practice may subject the Company to future liability for which it is only partially insured or is completely uninsured. In accordance with ASC Topic 450, Contingencies, ("ASC Topic 450") the Company records in its consolidated balance sheets amounts representing its estimated losses from claims and settlements when such losses are deemed probable and estimable. Otherwise these losses are expensed as incurred. Costs of defense are expensed as incurred. The Company undertakes an overall assessment of risk, and if the estimate of a probable loss is a range, and no amount within the range is a more reasonable estimate, the Company accrues the lower limit of the range. As additional information about current or future litigation or other contingencies becomes available, management will assess whether such information warrants the recording of changes in the expenses relating to those contingencies. Additional expenses could potentially have a material impact on the Company's business, financial condition, results of operations or cash flows.
Restricted Investments
Restricted Investments—Current and long-term restricted investments relate primarily to the Company's Exit Strategy contracts. Under the terms of the majority of Exit Strategy contracts, the contract proceeds were paid by the client to an insurer at inception. A portion of these proceeds, generally five to ten percent, were remitted to the Company. The balance of contract proceeds, less any insurance premiums and fees for a policy to cover potential cost overruns and other factors, were deposited into a restricted investment account with the insurer and are used to pay the Company as services are performed. Upon expiration of the related insurance policies, any remaining funds are remitted to the Company as provided in the policy. The deposited funds are recorded as restricted investments with a corresponding amount shown as deferred revenue on the Company's consolidated balance sheets. The current portion of the restricted investments represents the amount the Company estimates it will collect from the insurer over the next year.
As of June 30, 2013 and 2012, $28,072 and $33,599, respectively, of the restricted investments represent deposits which earn interest at the one-year constant maturity U.S. Treasury Bill rate, which rate is reset on the anniversary of each policy. As of June 30, 2013 and 2012 the one-year constant maturity U.S. Treasury Bill rate for such deposits ranged from 0.09% to 0.21% and from 0.09% to 0.30%, respectively.
Properties Available for Sale
Properties Available for Sale—Included in other assets are certain properties acquired in connection with certain Exit Strategy contracts that are available for sale in the amounts of $4,344 and $5,844 as of June 30, 2013 and 2012, respectively. The properties were recorded at fair value upon acquisition.
In cases where the Company does not expect to recover its carrying costs on properties available for sale, the Company reduces its carrying value to the fair value less costs to sell. During fiscal years 2013, 2012 and 2011, no impairment losses were recognized.
Capitalized Software
Capitalized Software—Internally used software, whether purchased or developed, is capitalized and amortized using the straight-line method over its estimated useful life. In accordance with ASC Subtopic 350-40, Internal-Use Software, the Company capitalizes certain costs associated with software such as costs of employees devoting time to the projects and external direct costs for materials and services. Costs associated with internally developed software to be used internally are expensed until the point at which the project has reached the development stage. Subsequent additions, modifications or upgrades to internal-use software are capitalized only to the extent that they allow the software to perform a task it previously did not perform. Software maintenance and training costs are expensed in the period in which they are incurred. The capitalization of software requires judgment in determining when a project has reached the development stage and the period over which the Company expects to benefit from the use of that software. The Company reviews the economic lives of its capitalized software annually. During fiscal years 2013, 2012 and 2011, capitalized software was amortized over three to five years.
Leases and Lease Financing Obligations
Leases and Lease Financing Obligations—The Company accounts for leases in accordance with ASC Topic 840, Leases. For lease agreements that provide for escalating rent payments and rent holidays, the Company recognizes rent expense on a straight-line basis over the non-cancellable lease term and option renewal periods where failure to exercise such options would result in an economic penalty such that renewal appears, at the inception of the lease, to be reasonably assured. The lease term commences when the Company becomes obligated under the terms of the lease agreement.
Self-Insurance Reserves
Self-Insurance Reserves—The Company has been self-insured for certain losses related to workers' compensation and employee medical benefits. Costs for self-insurance claims are accrued based on known claims and historical experience. Management believes that it has adequately reserved for its self-insurance liability, which is capped through the use of stop-loss contracts with insurance companies. However, any significant variation of future claims from historical trends could cause actual results to differ from the amount recorded. Once the stop-loss limit is reached for a given loss, the Company records a recoverable based on the terms of the self-insured plans.
Employee Benefit Plan
Employee Benefit Plan—The Company has a 401(k) savings plan covering substantially all employees. The Company's matching formula has two components. The basic match is up to 50% of each Participant's first 4% of contributed compensation, and the discretionary match of up to another 2% of contributed compensation is based on the Company's performance for the previous fiscal year. In fiscal years 2013, 2012 and 2011, the Company's contributions to the plan were approximately $3,444, $4,482 and $3,594, respectively. The Company does not provide post-employment or other post-retirement benefits.
Environmental Remediation Liabilities
Environmental Remediation Liabilities—The Company records environmental remediation liabilities for properties available for sale. The environmental remediation liabilities are initially recorded at fair value. The liability is reduced for actual costs incurred in connection with the clean-up activities for each property. In accordance with ASC Topic 405, Liabilities, upon completion of the capital phase of the clean-up, the environmental remediation liability is adjusted to equal the fair value of the remaining operation, maintenance and monitoring activities to be performed for the properties. The reduction in the liability resulting from the completion of the capital phase is included in insurance recoverables and other income. During fiscal years 2013, 2012 and 2011, no such income was recorded.
If it is determined that the expected costs of the clean-up activities are greater than the remaining environmental remediation liability for a specific property, the environmental remediation liability is adjusted pursuant to ASC Topic 410 Asset Retirement and Environmental Obligations ("ASC Topic 410"). Environmental remediation liabilities recorded pursuant to ASC Topic 410 are discounted when the amount and timing of the clean-up activities can be reliably determined. As of June 30, 2013 and 2012, the environmental liability for one project was discounted as the amount and timing of the remaining monitoring activities could be reliably determined. A discount of $374 and $378 was calculated using a risk-free discount rate of 2.3% and 4.1% as of June 30, 2013 and 2012, respectively. Estimated remediation costs for clean-up activities are based on experience, site conditions and the remedy selected. The liability is regularly adjusted as estimates are revised and as cleanup proceeds. Actual results could differ materially from those estimates. The undiscounted environmental liability as of June 30, 2013 and 2012 was $7,632 and $6,271, respectively.
Comprehensive Loss
Comprehensive Income (Loss)—The Company reports comprehensive income (loss) in accordance with ASC Topic 220, Comprehensive Income. Comprehensive income (loss) consists of net income (loss) and other gains and losses affecting equity that are not the result of transactions with owners.
Earnings Per Share
Earnings per Share—Upon issuance of the convertible preferred stock in June 2009, accounting guidance defining participating securities and the two class method of calculating EPS became applicable to the Company. The relevant guidance establishes standards regarding the computation of earnings (loss) per share by companies that have securities other than common stock that contractually entitle the holder to participate in dividends and earnings of the Company. The guidance also requires that earnings applicable to common shareholders for the period, after deduction of preferred stock dividends and accretion charges, be allocated between the common and preferred shareholders based on their respective rights to receive dividends. Basic earnings (loss) per share is then calculated by dividing the net income (loss) applicable to the Company's common shareholders by the weighted-average number of common shares outstanding.  
Diluted EPS is computed using the treasury stock method for stock options, warrants, non-vested restricted stock awards and units, and non-vested performance stock units. The treasury stock method assumes conversion of all potentially dilutive shares of common stock with the proceeds from assumed exercises used to hypothetically repurchase stock at the average market price for the period.  Diluted EPS is computed by dividing net income applicable to the Company by the weighted-average common shares and potentially dilutive common shares that were outstanding during the period.
For fiscal year 2011, the Company reported a net loss applicable to common shareholders; therefore, the potentially dilutive shares are anti-dilutive and are excluded from the calculation of diluted earnings (loss) per share in accordance with ASC Topic 260, Earnings Per Share. The holders of the convertible preferred stock did not have a contractual obligation to share in the net losses of the Company, and, as such, the undistributed net losses for fiscal year 2011 were not allocated to the convertible preferred stock. Because the effects were anti-dilutive, 7 preferred shares were excluded from the calculation of diluted EPS for fiscal year 2011 (prior to conversion). The preferred stock converted to common stock on December 1, 2010, resulting in the inclusion of 4,205 shares in the basic weighted-average shares outstanding for the fiscal year ended June 30, 2011. Because the effects were anti-dilutive, 3,004 of the 7,209 common shares from the preferred stock conversion on December 1, 2010 were excluded from the calculation of diluted EPS for the fiscal year ended June 30, 2011.
The following table sets forth the computations of basic and diluted EPS for the indicated fiscal years ended June 30:

Credit Risks
Credit Risks—Financial instruments which subject the Company to credit risk consist primarily of cash, accounts receivable, restricted investments, insurance recoverables, and investments in and advances to unconsolidated affiliates and construction joint ventures. The Company performs credit evaluations of its clients as required and maintains an allowance for estimated credit losses.
Fair Value of Financial Instruments
Fair Value of Financial Instruments—Cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities as reflected in the consolidated financial statements, approximate their fair values because of the short-term maturity of those instruments. The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The carrying amounts of the Company's subordinated notes payable as of June 30, 2013 and 2012, approximate fair value because the interest rates on the instruments change with market interest rates or because of the short term nature of their maturities. The carrying amount of the Company's remaining notes payable as of June 30, 2013 and 2012 approximate fair value as either the fixed interest rates approximate current rates for these obligations or the remaining term is not significant.
Use of Estimates
Use of Estimates—The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United States ("U.S. GAAP") necessarily requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ materially from those estimates.
New Accounting Pronouncements
New Accounting Pronouncements—In February 2013, the Financial Accounting Standards Board (“FASB”) issued new guidance requiring additional information about reclassification adjustments out of comprehensive income, including changes in comprehensive income balances by component and significant items reclassified out of comprehensive income. This new guidance will become effective for the Company beginning July 1, 2013. Other than requiring additional disclosures, the Company does not believe adoption of this new guidance will have a significant impact on its consolidated financial statements.
In July 2012, the FASB issued guidance establishing an optional two-step analysis for impairment testing of indefinite-lived intangibles other than goodwill. This new guidance allows an entity the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. Under that option, an entity no longer would be required to calculate the fair value of the intangible asset unless the entity determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The new guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, and early adoption is permitted. This new guidance will become effective for the Company beginning July 1, 2013. The Company is currently evaluating the impact this new guidance may have on its indefinite-lived intangibles impairment testing. The Company does not believe adoption of this new guidance will have a significant impact on its consolidated financial statements.
In December 2011, the FASB issued guidance enhancing disclosure requirements about the nature of an entity's right to offset, and related arrangements associated with, its financial instruments and derivative instruments. The new guidance requires the disclosure of the gross amounts subject to rights of set-off, amounts offset, and the related net exposure. The new guidance will be effective for the Company beginning July 1, 2013. Other than requiring additional disclosures, the Company does not believe adoption of this new guidance will have a significant impact on its consolidated financial statements.
In September 2011, the FASB issued guidance on testing goodwill for impairment. The new guidance provides an entity the option to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If an entity determines that this is the case, it is required to perform the currently prescribed two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized for that reporting unit (if any). If an entity determines that the fair value of a reporting unit is greater than its carrying amount, the two-step goodwill impairment test is not required. The Company adopted this new guidance beginning July 1, 2012. Adoption of this new guidance did not have a significant impact on the Company's consolidated financial statements.
In June 2011, the FASB issued guidance on the presentation of comprehensive income. The new guidance eliminated the option to report other comprehensive income and its components in the statement of changes in equity. Instead, an entity is required to present net income and other comprehensive income in either a continuous statement or in two separate but consecutive statements. The Company adopted this new guidance beginning July 1, 2012. Adoption of this new guidance resulted only in changes to the presentation of the Company's consolidated financial statements.
