New Accounting Pronouncements and Changes in Accounting
New Accounting Pronouncements and Changes in Accounting	2. New Accounting Pronouncements and Changes in Accounting In February 2013, the Financial Accounting Standards Board (FASB) issued new accounting guidance to update the presentation of reclassifications from comprehensive income to net income in consolidated financial statements. Under this new guidance, an entity is required to present information about the amounts reclassified out of accumulated other comprehensive income either by the respective line items of net income or by cross-reference to other required disclosures. The new guidance does not change the requirements for reporting net income or other comprehensive income in financial statements. This guidance was effective for the Company’s fiscal year beginning October 1, 2013 and did not have a material impact on the Company’s consolidated financial statements. In February 2013, the FASB issued new accounting guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation (within the scope of this guidance) is fixed at the reporting date. Examples of obligations within the scope of this guidance include debt arrangements, other contractual obligations, and settled litigation and judicial rulings. This new guidance was effective for annual reporting periods beginning after December 15, 2013 and subsequent interim periods. This guidance is effective for the Company’s fiscal year beginning October 1, 2014 and it is not expected to have a material impact on the Company’s consolidated financial statements. In July 2013, the FASB issued new accounting guidance that requires the presentation of unrecognized tax benefits as a reduction of the deferred tax assets, when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. This new guidance was effective for annual reporting periods beginning on or after December 15, 2013 and subsequent interim periods. This guidance is effective for the Company’s fiscal year beginning October 1, 2014 and it is not expected to have a material impact on the Company’s consolidated financial statements. In May 2014, the FASB issued new accounting guidance which amended the existing accounting standards for revenue recognition. The new accounting guidance establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. This guidance is effective for the Company’s fiscal year beginning October 1, 2017. Early adoption is not permitted. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The Company is currently in the process of evaluating the impact of adoption of the new accounting guidance on its consolidated financial statements.

The Company determines the final value of the identifiable intangible assets as soon as information is available, but not more than 12 months from the date of acquisition. Post-acquisition adjustments primarily relate to project related liabilities.

The changes in the carrying value of goodwill by reportable segment for the nine months ended June 30, 2014 and 2013 were as follows:

Billed accounts receivable represent amounts billed to clients that have yet to be collected. Unbilled accounts receivable represent revenue recognized but not yet billed pursuant to contract terms or accounts billed after the period end. Substantially all unbilled receivables as of June 30, 2014 and September 30, 2013 are expected to be billed and collected within twelve months. Contract retentions represent amounts invoiced to clients where payments have been withheld pending the completion of certain milestones, or other contractual conditions, or upon the completion of a project. These retention agreements vary from project to project and could be outstanding for several months or years.

Allowances for doubtful accounts have been determined through specific identification of amounts considered to be uncollectible and potential write-offs, plus a non-specific allowance for other amounts for which some potential loss has been determined to be probable based on current and past experience.

Other than the U.S. government, no single client accounted for more than 10% of the Company’s outstanding receivables at June 30, 2014 or September 30, 2013.

The Company has sold trade receivables to financial institutions, of which $116.1 million and $100.2 million was outstanding as of June 30, 2014 and September 30, 2013, respectively. The Company does not retain financial or legal obligations for these receivables that would result in material losses. The Company’s ongoing involvement is limited to the remittance of customer payments to the financial institutions with respect to the sold trade receivables.

6. Joint Ventures and Variable Interest Entities

The Company’s joint ventures provide architecture, engineering, program management, construction management and operations and maintenance services. Joint ventures, the combination of two or more partners, are generally formed for a specific project. Management of the joint venture is typically controlled by a joint venture executive committee, comprised of representatives from the joint venture partners. The joint venture executive committee normally provides management oversight and controls decisions which could have significant impact on the joint venture.

Some of the Company’s joint ventures have no employees and minimal operating expenses. For these joint ventures, the Company’s employees perform work for the joint venture, which is then billed to a third-party customer by the joint venture. These joint ventures function as pass through entities to bill the third-party customer. For consolidated joint ventures of this type, the Company records the entire amount of the services performed and the costs associated with these services, including the services provided by the other joint venture partners, in the Company’s results of operations. For certain of these joint ventures where a fee is added by an unconsolidated joint venture to client billings, the Company’s portion of that fee is recorded in equity in earnings of joint ventures.

The Company also has joint ventures that have their own employees and operating expenses, and to which the Company generally makes a capital contribution. The Company accounts for these joint ventures either as consolidated entities or equity method investments based on the criteria further discussed below.

The Company follows guidance issued by the FASB on the consolidation of variable interest entities (VIEs) that requires companies to utilize a qualitative approach to determine whether it is the primary beneficiary of a VIE. The process for identifying the primary beneficiary of a VIE requires consideration of the factors that indicate a party has the power to direct the activities that most significantly impact the joint venture’s economic performance, including powers granted to the joint venture’s program manager, powers contained in the joint venture governing board and, to a certain extent, a company’s economic interest in the joint venture. The Company analyzes its joint ventures and classifies them as either:

· a VIE that must be consolidated because the Company is the primary beneficiary or the joint venture is not a VIE and the Company holds the majority voting interest with no significant participative rights available to the other partners; or

· a VIE that does not require consolidation and is treated as an equity method investment because the Company is not the primary beneficiary or the joint venture is not a VIE and the Company does not hold the majority voting interest.

As part of the above analysis, if it is determined that the Company has the power to direct the activities that most significantly impact the joint venture’s economic performance, the Company considers whether or not it has the obligation to absorb losses or rights to receive benefits of the VIE that could potentially be significant to the VIE.

The Company has not provided financial or other support during the periods presented to any of its VIEs that it was not previously contractually required to provide. Contractually required support provided to the Company’s joint ventures is further discussed in Note 16.

Total revenue of the unconsolidated joint ventures was $1,455.3 million and $1,504.6 million for the nine months ended June 30, 2014 and 2013, respectively. Total gross profit, which also equates to net income, of the unconsolidated joint ventures was $39.1 million and $49.5 million for the nine months ended June 30, 2014 and 2013, respectively.

Summary of AECOM’s equity in earnings of unconsolidated joint ventures is as follows:

	Nine Months Ended

Included in equity in earnings above, the Company recorded a $37.4 million gain upon change in control ($23.4 million, net of tax) of an unconsolidated joint venture in the nine months ended June 30, 2014. The Company obtained control of the joint venture through modifications to the joint venture’s operating agreement, which required the Company to consolidate the joint venture. The acquisition date fair value of the previously held equity interest was $58.0 million, excluding control premium. The measurement of the fair value of the equity interest immediately before obtaining control of the joint venture resulted in the pre-tax gain of $37.4 million. The Company utilized income and market approaches, in addition to obtaining an independent third party valuation, in determining the joint venture’s fair value, which includes making assumptions about variables such as revenue growth rates, profitability, discount rates, and industry market multiples. These assumptions are subject to a high degree of judgment. Total assets and liabilities of this entity included in the accompanying consolidated balance sheet at the acquisition date were $207.8 million and $48.1 million, respectively. This acquisition did not meet the quantitative thresholds to require pro forma disclosures of operating results based on the Company’s consolidated assets, investments and net income. This joint venture performs engineering and program management services in the Middle East and is included in the Company’s PTS segment.

Unsecured Term Credit Agreement

In June 2013, the Company entered into a Second Amended and Restated Credit Agreement (Term Credit Agreement) with Bank of America, N.A., as administrative agent and a lender, and the other lenders party thereto. Pursuant to the Term Credit Agreement, the Company borrowed $750 million and may borrow up to an additional $100 million subject to certain conditions, including lender approval. The Company used approximately $675 million of the proceeds from the loans to repay indebtedness under its prior term loan facility. The loans under the Term Credit Agreement bear interest, at the Company’s option, at either the Base Rate (as defined in the Term Credit Agreement) plus an applicable margin or the Eurodollar Rate (as defined in the Term Credit Agreement) plus an applicable margin. The applicable margin for the Base Rate loans is a range of 0.125% to 1.250% and the applicable margin for Eurodollar Rate loans is a range of 1.125% to 2.250%, both based on the debt-to-earnings leverage ratio of the Company at the end of each fiscal quarter. For the nine months ended June 30, 2014 and 2013, the average interest rate of the Company’s term loan facility was 1.66% and 1.98%, respectively. Payments of the initial principal amount outstanding under the Term Credit Agreement are required on an annual basis beginning on June 30, 2014 with the final principal balance of $600 million due on June 7, 2018. The Company may, at its option, prepay the loans at any time, without penalty. The Company’s obligations under the Term Credit Agreement are guaranteed by certain subsidiaries of the Company pursuant to one or more subsidiary guarantees.

Unsecured Senior Notes

In July 2010, the Company issued $300 million of notes to private institutional investors. The notes consisted of $175.0 million of 5.43% Senior Notes, Series A, due July 2020 and $125.0 million of 1.00% Senior Discount Notes, Series B, due July 2022 for net proceeds of $249.8 million. The outstanding accreted balance of Series B Notes, which have an effective interest rate of 5.62%, was $87.9 million and $85.2 million at June 30, 2014 and September 30, 2013, respectively. The fair value of the Company’s unsecured senior notes was approximately $282.1 million and $269.4 million at June 30, 2014 and September 30, 2013, respectively. The Company calculated the fair values based on model-derived valuations using market observable inputs, which are Level 2 inputs under the accounting guidance. The Company’s obligations under the notes are guaranteed by certain subsidiaries of the Company pursuant to one or more subsidiary guarantees. The Company may, at its option, prepay the notes at any time at their called principal amount, together with any accrued and unpaid interest, plus a make-whole premium.

Unsecured Revolving Credit Facility

In January 2014, the Company entered into a Fourth Amended and Restated Credit Agreement (Revolving Credit Agreement), which provides for a borrowing capacity of $1.05 billion. The Revolving Credit Agreement expires January 29, 2019, and prior to this expiration date, principal amounts outstanding under the Revolving Credit Agreement may be repaid and reborrowed at the Company’s option without prepayment or penalty, subject to certain conditions including the absence of any event of default. The Company may request an increase in capacity of up to a total of $1.25 billion, subject to certain conditions including the absence of any event of default. The loans under the Revolving Credit Agreement may be borrowed in dollars or in certain foreign currencies and bear interest, at the Company’s option, at either the Base Rate (as defined in the Revolving Credit Agreement) plus an applicable margin or the Eurocurrency Rate (as defined in the Revolving Credit Agreement) plus an applicable margin. The applicable margin for the Base Rate loans is a range of 0.125% to 1.250% and the applicable margin for the Eurocurrency Rate loans is a range of 1.125% to 2.250%, both based on the Company’s debt-to-earnings leverage ratio at the end of each fiscal quarter. In addition to these borrowing rates, there is a commitment fee which ranges from 0.125% to 0.350% on any unused commitment. At June 30, 2014 and September 30, 2013, $0.0 million and $114.7 million, respectively, were outstanding under the Company’s revolving credit facility. At June 30, 2014 and September 30, 2013, outstanding standby letters of credit totaled $9.5 million and $35.5 million, respectively, under the revolving credit facility. As of June 30, 2014, the Company had $1,040.5 million available under its Revolving Credit Agreement.

Covenants and Restrictions

Under the Company’s debt agreements relating to its unsecured revolving credit facility, unsecured term credit agreement, and unsecured senior notes, the Company is subject to a maximum consolidated leverage ratio at the end of each fiscal quarter. This ratio is calculated by dividing consolidated funded debt (including financial letters of credit and other adjustments per the Company’s debt agreements) by consolidated earnings before interest, taxes, depreciation, and amortization (EBITDA). Subject to certain differences among the Company’s debt agreements, EBITDA is defined as consolidated net income attributable to AECOM plus interest, depreciation and amortization expense, amounts set aside for taxes and other non-cash items (including a calculated annualized EBITDA from acquisitions). As of June 30, 2014, the Company’s most restrictive consolidated leverage ratio under its debt agreements was 2.54, which did not exceed the Company’s maximum consolidated leverage ratio permitted under the Company’s debt agreements of 3.0.

The Company’s Revolving Credit Agreement and Term Credit Agreement also contain certain covenants that limit the Company’s ability to, among other things, (i) merge with other entities, (ii) enter into a transaction resulting in a change of control, (iii) create new liens, (iv) sell assets outside of the ordinary course of business, (v) enter into transactions with affiliates, (vi) substantially change the general nature of the Company and its subsidiaries taken as a whole, and (vii) incur indebtedness and contingent obligations.

Additionally, the Company’s unsecured senior notes contain covenants that limit (i) certain types of indebtedness, which include indebtedness incurred by subsidiaries and indebtedness secured by a lien, (ii) merging with other entities, (iii) entering into a transaction resulting in a change of control, (iv) creating new liens, (v) selling assets outside of the ordinary course of business, (vi) entering into transactions with affiliates, and (vii) substantially changing the general nature of the Company and its subsidiaries taken as a whole. The unsecured senior notes also contain a financial covenant that requires the Company to maintain a net worth above a calculated threshold. The threshold is calculated as $1.2 billion plus 40% of the consolidated net income for each fiscal quarter commencing with the fiscal quarter ending June 30, 2010. In the calculation of this threshold, the Company cannot include a consolidated net loss that may occur in any fiscal quarter. The Company’s net worth for this financial covenant is defined as total AECOM stockholders’ equity, which is consolidated stockholders’ equity, including any redeemable common stock and stock units and the liquidation preference of any preferred stock. As of June 30, 2014, this amount was $2.2 billion, which exceeds the calculated threshold of $1.7 billion.

Should the Company fail to comply with these covenants, all or a portion of its borrowings under the unsecured senior notes and unsecured term credit agreements could become immediately payable and its unsecured revolving credit facility could be terminated. At June 30, 2014 and September 30, 2013, the Company was in compliance with all such covenants.

The Company’s average effective interest rate on total borrowings, including the effects of the interest rate swap agreements, during the nine months ended June 30, 2014 and 2013 was 2.8% and 3.0%, respectively.

Other Debt

Other debt consists primarily of bank overdrafts and obligations under capital leases and other unsecured credit facilities. In addition to the unsecured revolving credit facility discussed above, the Company also has other unsecured credit facilities primarily used for standby letters of credit issued for payment and performance guarantees. At June 30, 2014 and September 30, 2013, these outstanding standby letters of credit totaled $274.8 million and $236.4 million, respectively. As of June 30, 2014, the Company had $332.9 million available under these unsecured credit facilities.

Derivative Financial Instruments

Derivative Financial Instruments

Derivative Financial Instruments

9. Derivative Financial Instruments

The Company uses certain interest rate derivative contracts to hedge interest rate exposures on the Company’s variable rate debt. The Company enters into foreign currency derivative contracts with financial institutions to reduce the risk that its cash flows and earnings will be adversely affected by foreign currency exchange rate fluctuations. The Company’s hedging program is not designated for trading or speculative purposes.

The Company recognizes derivative instruments as either assets or liabilities on the accompanying consolidated balance sheets at fair value. The Company records changes in the fair value (i.e., gains or losses) of the derivatives that have been designated as accounting hedges in the accompanying consolidated statements of income as cost of revenue, interest expense or to accumulated other comprehensive loss in the accompanying consolidated balance sheets.

Cash Flow Hedges

The Company uses interest rate swap agreements designated as cash flow hedges to fix the variable interest rates on portions of the Company’s debt. The Company also uses foreign currency options designated as cash flow hedges to hedge forecasted revenue transactions denominated in currencies other than the U.S. dollar. The Company initially reports any gain on the effective portion of a cash flow hedge as a component of accumulated other comprehensive loss. Depending on the type of cash flow hedge, the gain is subsequently reclassified to either interest expense when the interest expense on the variable rate debt is recognized, or to cost of revenue when the hedged revenues are recorded. If the hedged transaction becomes probable of not occurring, any gain or loss related to interest rate swap agreements or foreign currency options would be recognized in other income (expense). Further, the Company excludes the change in the time value of the foreign currency options from the assessment of hedge effectiveness. The Company records the premium paid or time value of an option on the date of purchase as an asset. Thereafter, the Company recognizes any change to this time value in cost of revenue.

The notional principal, fixed rates and related expiration dates of the Company’s outstanding interest rate swap agreements were as follows:

June 30, 2014
Notional Amount (in millions)		Fixed Rate		Expiration Date
$	300.0	1.63	%	June 2018
250.0		0.95	%	September 2015
200.0		0.68	%	December 2014

September 30, 2013
Notional Amount (in millions)		Fixed Rate		Expiration Date
$	250.0	0.95	%	September 2015
200.0		0.68	%	December 2014
150.0		0.55	%	December 2013

The notional principal of foreign currency options to purchase British Pounds (GBP) with Brazilian Reals (BRL) was BRL 1.1 million and BRL 2.1 million (or approximately $0.5 million and $0.9 million) at June 30, 2014 and September 30, 2013, respectively. These foreign exchange contracts have maturities of 12 months or less.

Foreign Currency Forward Contracts

The Company uses foreign currency forward contracts, which are not designated as accounting hedges, to hedge intercompany transactions and other monetary assets or liabilities denominated in currencies other than the functional currency of a subsidiary. Gains and losses on these contracts are recognized in cost of revenue for those instruments related to the provision of their respective services or general and administrative expenses, along with the offsetting losses and gains of the related hedged items. The notional principal of foreign currency forward contracts to purchase U.S. dollars with foreign currencies was $93.8 million and $171.8 million at June 30, 2014 and September 30, 2013, respectively. The notional principal of foreign currency forward contracts to sell U.S. dollars for foreign currencies was $59.9 million and $174.2 million at June 30, 2014 and September 30, 2013, respectively. The notional principal of foreign currency forward contracts to purchase GBP with BRL was BRL 4.0 million (or approximately $1.8 million) at September 30, 2013. There were no foreign currency forward contracts to purchase GBP with BRL at June 30, 2014. The notional principal of foreign currency forward contracts to sell GBP for BRL was BRL 4.1 million and BRL 8.2 million (or approximately $1.9 million and $3.6 million) at June 30, 2014 and September 30, 2013, respectively.

Other Derivatives

Other derivatives that are not designated as hedging instruments consist of option contracts that the Company uses to hedge anticipated transactions in currencies other than the functional currency of a subsidiary. The Company recognizes gains and losses on these contracts as well as the offsetting losses and gains of the related hedged item costs in cost of revenue. The Company records the premium paid or time value of an option on the date of purchase as an asset. Thereafter, the Company recognizes any change to this time value in cost of revenue. There was no such option contract outstanding during the periods presented.

The fair values of our outstanding derivative instruments were as follows (in millions):

Fair Value Measurements

Fair Value Measurements

Fair Value Measurements

10. Fair Value Measurements

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value, the Company considers the principal or most advantageous market in which it would transact, and the Company considers assumptions that market participants would use when pricing the asset or liability. It measures certain financial and nonfinancial assets and liabilities at fair value on a recurring and nonrecurring basis.

Nonfinancial assets and liabilities include items such as goodwill and long lived assets that are measured at fair value resulting from impairment, if deemed necessary. During the nine months ended June 30, 2014 and 2013, the Company did not record any fair value adjustments to those financial and nonfinancial assets and liabilities measured at fair value on a nonrecurring basis.

Fair Value Hierarchy

The three levels of inputs that may be used to measure fair value are as follows:

· Level 1 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 within Level 1, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable market data for substantially the full term of the assets or liabilities.

· Level 3 Unobservable inputs that are significant to the measurement of the fair value of assets or liabilities.

The following table summarizes the Company’s non-pension financial assets and liabilities measured at fair value on a recurring basis (at least annually) in millions:

	June 30, 2014		Quoted Prices in Active Markets for Identical Assets (Level 2)
Foreign currency options	$	0.1	$	0.1
Foreign currency forward contracts	1.5		1.5
Total assets	$	1.6	$	1.6

Interest rate swap agreements	$	4.7	$	4.7
Foreign currency forward contracts	0.8		0.8
Total liabilities	$	5.5	$	5.5

	September 30, 2013		Quoted Prices in Active Markets for Similar Assets (Level 2)
Foreign currency options	$	0.1	$	0.1
Foreign currency forward contracts	1.6		1.6
Total assets	$	1.7	$	1.7

Interest rate swap agreements	$	3.7	$	3.7
Foreign currency forward contracts	1.5		1.5
Total liabilities	$	5.2	$	5.2

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Share-based Payments

Share-based Payments

11. Share-based Payments

The fair value of the Company’s employee stock option awards is estimated on the date of grant. The expected term of awards granted represents the period of time the awards are expected to be outstanding. The risk-free interest rate is based on U.S. Treasury bond rates with maturities equal to the expected term of the option on the grant date. The Company uses historical data as a basis to estimate the probability of forfeitures.

Stock option activity for the nine months ended June 30 was as follows:

	2014				2013
	Shares of stock under options		Weighted average exercise price		Shares of stock under options		Weighted average exercise price
	(in millions)				(in millions)
Outstanding at September 30, prior year	1.6		$	24.73	2.5		$	22.81
Options granted	0.6		31.62		—		—

Vested and expected to vest in the future as of June 30	1.7		$	27.57	1.7		$	24.32

The Company grants stock units to employees under its Performance Earnings Program (PEP), whereby units are earned and issued dependent upon meeting established cumulative performance objectives over a two or three-year period. Additionally, the Company issues restricted stock units to employees which are earned based on service conditions. Total compensation expense related to share-based payments was $26.0 million and $27.4 million during the nine months ended June 30, 2014 and 2013, respectively. Unrecognized compensation expense related to total share-based payments outstanding was $68.9 million and $52.6 million as of June 30, 2014 and September 30, 2013, respectively, to be recognized on a straight-line basis over the awards’ respective vesting periods which are generally three years.

Cash flows attributable to tax benefits resulting from tax deductions in excess of compensation cost recognized for those stock options (excess tax benefits) is classified as financing cash flows. Excess tax benefits of $0.6 million and $1.8 million for the nine months ended June 30, 2014 and 2013, respectively, have been classified as financing cash inflows in the consolidated statements of cash flows.

Income Taxes	9 Months Ended

Income Taxes	12. Income Taxes The Company’s effective tax rate was 23.7% and 25.6% for the nine months ended June 30, 2014 and 2013, respectively. The Company’s effective tax rate is lower than the federal statutory rate of 35.0% primarily due to the tax rate differential on foreign earnings where the statutory rates are generally lower than the federal statutory rate. Our effective tax rate fluctuates from quarter to quarter due to several factors including the change in the mix of foreign and domestic earnings, tax law changes, outcomes of administrative audits, changes in our assessment of valuation allowances and other tax contingencies.

Earnings Per Share

Earnings Per Share

13. Earnings Per Share

Basic earnings per share (EPS) excludes dilution and is computed by dividing net income available for common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net income by the weighted average number of common shares outstanding and potential common stock equivalent shares for the period. The Company includes as potential common shares the weighted average dilutive effects of outstanding stock options and restricted stock units using the treasury stock method.

The following table sets forth a reconciliation of the denominators for basic and diluted earnings per share:

	Three Months Ended		Nine Months Ended
	June 30, 2014	June 30, 2013	June 30, 2014	June 30, 2013

Potential common shares	1.5	1.5	1.4	1.2
Denominator for diluted earnings per share	99.0	100.8	98.3	102.7

EPS includes the effect of repurchased shares, which are discussed in Note 3 herein. For the nine months ended June 30, 2014 and 2013, options excluded from the calculation of potential common shares were not significant.

Commitments and Contingencies	9 Months Ended
Commitments and Contingencies	Jun. 30, 2014
Commitments and Contingencies
Commitments and Contingencies	16. Commitments and Contingencies The Company records amounts representing its probable estimated liabilities relating to claims, guarantees, litigation, audits and investigations. The Company relies in part on qualified actuaries to assist it in determining the level of reserves to establish for insurance-related claims that are known and have been asserted against it, and for insurance-related claims that are believed to have been incurred based on actuarial analysis, but have not yet been reported to the Company’s claims administrators as of the respective balance sheet dates. The Company includes any adjustments to such insurance reserves in its consolidated results of operations. The Company is a defendant in various lawsuits arising in the normal course of business. In the opinion of management, the ultimate resolution of these matters will not have a material adverse effect on its consolidated balance sheet or statements of income or cash flows. In some instances, the Company guarantees that a project, when complete, will achieve specified performance standards. If the project subsequently fails to meet guaranteed performance standards, the Company may either incur additional costs or be held responsible for the costs incurred by the client to achieve the required performance standards. At June 30, 2014, the Company was contingently liable in the amount of approximately $284.3 million under standby letters of credit issued primarily in connection with general and professional liability insurance programs and for payment and performance guarantees. In the ordinary course of business, the Company enters into various agreements providing financial or performance assurances to clients on behalf of certain unconsolidated partnerships, joint ventures and other jointly executed contracts. These agreements are entered into primarily to support the project execution commitments of these entities. The guarantees have various expiration dates. The maximum potential payment amount of an outstanding performance guarantee is the remaining cost of work to be performed by or on behalf of third parties. On projects where the Company has additional exposure including for delay or consequential damages, the policy is to cap those damages in order to limit this exposure and, in any case, to cap the performance guarantees themselves. Generally, under joint venture arrangements, if a partner is financially unable to complete its share of the contract, the other partner(s) will be required to complete those activities. The Company generally only enters into joint venture arrangements with partners who are reputable, financially sound and who carry appropriate levels of surety bonds for the project in order to adequately assure completion of their assignments. The Company does not expect that these guarantees will have a material adverse effect on its consolidated balance sheet or statements of income or cash flows. *AECOM Australia* In 2005 and 2006, the Company’s main Australian subsidiary, AECOM Australia Pty Ltd (AECOM Australia), performed a traffic forecast assignment for a client consortium as part of their project to design, build, finance and operate a tolled motorway tunnel in Australia. To fund the motorway’s design and construction, the client formed certain special purpose vehicles (SPV) that raised approximately $700 million Australian dollars through an initial public offering (IPO) of equity units in 2006 and approximately an additional $1.4 billion Australian dollars in long term bank loans. The SPV (and certain affiliated SPVs) went into insolvency administrations in February 2011. KordaMentha, the receivers for the SPV and certain affiliated SPVs (the RCM Applicants), caused a lawsuit to be filed against AECOM Australia by the RCM Applicants in the Federal Court of Australia on May 14, 2012. Portigon AG (formerly WestLB AG), one of the lending banks to the SPVs, filed a lawsuit in the Federal Court of Australia against AECOM Australia on May 18, 2012. Separately, a class action lawsuit, which has been amended to include approximately 770 of the IPO investors, was filed against AECOM Australia in the Federal Court of Australia on May 31, 2012. All of the lawsuits claim damages that purportedly resulted from AECOM Australia’s role in connection with the above described traffic forecast. The RCM Applicants have claimed damages of approximately $1.68 billion Australian dollars (including interest, as of March 31, 2014). The damages claimed by Portigon as of June 17, 2014 were also recently quantified at approximately $76 million Australian dollars (including interest). This claim is duplicative of damages already included in the RCM Applicants’ claim to the extent Portigon receives a portion of the RCM Applicants’ recovery. The class action applicants claim that they represent investors who acquired approximately $155 million Australian dollars of securities. AECOM Australia disputes the claimed entitlements to damages asserted by all applicants and is vigorously defending the claims brought against it. The likely resolution of these matters cannot be reasonably determined at this time. However, if these matters are not resolved in AECOM Australia’s favor then, depending upon the outcomes, it could have a material adverse effect on the Company’s results of operations. *Litigation Related to the Merger* As discussed in Note 18, on July 11, 2014, we entered into a definitive merger agreement to acquire URS Corporation. In connection with the merger, beginning on July 21, 2014, five putative class action lawsuits were filed in the Court of Chancery of the State of Delaware by purported URS Corporation stockholders: Falato v. URS Corp., et al., Case No. 9921; City of Atlanta Firefighters’ Pension Fund v. Creel, et al., Case No. 9924; Petroutson v. URS Corp., et al., Case No. 9938; Miller v. URS Corp., et al., Case No. 9939; and Oklahoma Police Pension & Retirement System v. Creel, et al., Case No. 9975. The actions name as defendants URS Corporation, the members of the URS Corporation board of directors, AECOM, and two merger subsidiaries of AECOM formed for purposes of effecting the merger. Two of the actions also names as a defendant JANA Partners LLC. The complaints allege, among other things, that AECOM and its merger subsidiaries aided and abetted alleged breaches of fiduciary duties by URS Corporation and its board of directors. The complaints seek, among other relief, class certification, preliminary and permanent injunctive relief, and damages. AECOM believe the lawsuits are without merit and intends to defend vigorously against them.

17. Reportable Segments

The Company’s operations are organized into two reportable segments: Professional Technical Services (PTS) and Management Support Services (MSS). The Company’s PTS reportable segment delivers planning, consulting, architectural and engineering design, and program and construction management services to commercial and government clients worldwide. The Company’s MSS reportable segment provides program and facilities management and maintenance, training, logistics, consulting, and technical assistance and systems integration services, primarily for agencies of the U.S. government. These reportable segments are organized by the types of services provided, the differing specialized needs of the respective clients, and how the Company manages its business. The Company has aggregated various operating segments into its PTS reportable segment based on their similar characteristics, including similar long-term financial performance, the nature of services provided, internal processes for delivering those services, and types of customers.

Management internally analyzes the results of its operations using several non-GAAP measures. A significant portion of the Company’s revenues relates to services provided by subcontractors and other non-employees that it categorizes as other direct costs. Other direct costs are segregated from cost of revenues resulting in revenue, net of other direct costs, which is a measure of work performed by Company employees. The Company has included information on revenue, net of other direct costs, as it believes that it is useful to view its revenue exclusive of costs associated with external service providers.

The following tables set forth summarized financial information concerning the Company’s reportable segments:

Subsequent Events
Subsequent Events	18. Subsequent Events On July 11, 2014, the Company entered into a definitive merger agreement to acquire URS Corporation, a leading international provider of engineering, construction and technical services for approximately $4.0 billion. The acquisition is subject to customary closing conditions, including regulatory approvals, adoption of the definition merger agreement by URS stockholders and approval of the stock issuance proposal by AECOM stockholders. Both AECOM and URS may terminate the merger agreement under certain specified circumstances, including if the merger is not consummated on or before April 11, 2015 (or, if such date is extended pursuant to the terms of the merger agreement, if the merger is not consummated on or before July 11, 2015), if the approval of the AECOM or URS stockholders is not obtained, if there is a financing failure, if the other party’s board of directors makes an adverse recommendation change with respect to the proposed transaction, or to enter into a superior acquisition proposal. In certain circumstances in connection with the termination of the merger agreement, including if AECOM’s board of directors changes or withdraws its recommendation of the stock issuance or terminates the merger agreement to enter into an agreement with respect to a superior proposal, AECOM must pay to URS a termination fee equal to $140 million, or $240 million if the merger agreement is terminated under circumstances where all closing conditions have been satisfied but AECOM’s debt financing is not available to complete the merger and AECOM fails to close the merger. In certain circumstances in connection with the termination of the merger agreement, including if URS’s board of directors changes or withdraws its recommendation of the merger or terminates the merger agreement to enter into an agreement with respect to a superior proposal, URS must pay to AECOM a termination fee equal to $140 million. If the merger agreement is terminated by a party as a result of certain breaches by the other party, then the non-terminating party will be required to reimburse the terminating party for its reasonable out-of-pocket fees and expenses up to $40 million. On July 24, 2014, the Company acquired Hunt Construction Group, a commercial construction management firm which serves clients in both the public and private sectors.

- Definition

Accumulated change in equity from transactions and other events and circumstances from non-owner sources, net of tax effect, at period end. Excludes Net Income (Loss), and accumulated changes in equity from transactions resulting from investments by owners and distributions to owners. Includes foreign currency translation items, certain pension adjustments, unrealized gains and losses on certain investments in debt and equity securities, other than temporary impairment (OTTI) losses related to factors other than credit losses on available-for-sale and held-to-maturity debt securities that an entity does not intend to sell and it is not more likely than not that the entity will be required to sell before recovery of the amortized cost basis, as well as changes in the fair value of derivatives related to the effective portion of a designated cash flow hedge.
