PART I

ITEM 1.    BUSINESS

In this report, we use the terms "AECOM," "the Company," "we," "us" and "our" to refer to AECOM Technology Corporation and its consolidated subsidiaries. Unless otherwise noted, references to years are for fiscal years. Our fiscal year consists of 52 or 53 weeks, ending on the Friday closest to September 30. For clarity of presentation, we present all periods as if the year ended on September 30. We refer to the fiscal year ended September 30, 2011, as "fiscal 2011" and the fiscal year ended September 30, 2012, as "fiscal 2012."

Overview

        We are a leading global provider of professional technical and management support services for public and private clients around the world. We provide planning, consulting, architectural and engineering design, and program and construction management services for a broad range of projects, including highways, airports, bridges, mass transit systems, government and commercial buildings, water and wastewater facilities and power transmission and distribution. We also provide program and facilities management and maintenance, training, logistics, security and other support services, primarily for agencies of the U.S. government.

        Through our network of approximately 46,800 employees (as of September 30, 2012), we provide our services in a broad range of end markets, including the transportation, facilities, environmental, energy, water and government markets. According to Engineering News-Record's (ENR's) 2012 Design Survey, we are the largest general architectural and engineering design firm in the world, ranked by 2011 design revenue. In addition, we are ranked by ENR as the leading firm in a number of design end markets, including transportation and general building.

        We were formed in 1980 as Ashland Technology Company, a Delaware corporation and a wholly-owned subsidiary of Ashland, Inc., an oil and gas refining and distribution company. Since becoming independent of Ashland Inc., we have grown by a combination of organic growth and strategic mergers and acquisitions from approximately 3,300 employees and $387 million in revenue in fiscal 1991, the first full fiscal year of independent operations, to approximately 46,800 employees at September 30, 2012, and $8.2 billion in revenue for fiscal 2012. We completed the initial public offering of our common stock in May 2007 and such shares are traded on the New York Stock Exchange.

        We offer our services through two business segments: Professional Technical Services and Management Support Services.

        Professional Technical Services (PTS).    Our PTS segment delivers planning, consulting, architectural and engineering design, and program and construction management services to commercial and government clients worldwide in major end markets such as transportation, facilities, environmental, energy, water and government markets. For example, we are providing program management services through a joint venture for the Second Avenue subway line in New York City, design and contract administration services for the Hong Kong-Zhuhai-Macao Bridge's Hong Kong Boundary Crossing Facilities and engineering and environmental management services to support global energy infrastructure development for a number of large petroleum and mining companies. Our PTS segment contributed $7.3 billion, or 89%, of our fiscal 2012 revenue.

        Management Support Services (MSS).    Our MSS segment provides program and facilities management and maintenance, training, logistics, consulting, technical assistance and systems integration services, primarily for agencies of the U.S. government. For example, we oversee remote field experiments, multiple laboratory operations, waste management systems, and the design and fabrication of electronic, mechanical and structural systems at the U.S. Department of Energy's Nevada Test Site. Our MSS segment contributed $0.9 billion, or 11%, of our fiscal 2012 revenue.

Our Business Strategy

        Our business strategy focuses on leveraging our competitive strengths and leadership positions in our core markets while opportunistically entering new and emerging markets and geographies. Key elements of our strategy include:

Expand our long-standing client relationships and provide our clients with a broad range of services

        We have long-standing relationships with a number of large corporations, public and private institutions and government agencies worldwide. We will continue to focus on client satisfaction along with opportunities to sell a greater range of services to clients and deliver full-service solutions for their needs. For example, as our environmental business has grown, we have provided environmental services for transportation and other infrastructure projects where such services have in the past been subcontracted to third parties.

        By integrating and providing a broad range of services, we believe we deliver maximum value to our clients at competitive costs. Also, by coordinating and consolidating our knowledge base, we believe we have the ability to export our leading edge technical skills to any region in the world in which our clients may need them.

Capitalize on opportunities in our core markets

        We intend to leverage our leading positions in the transportation, facilities, environmental, energy, water and government markets to continue to expand our services and revenue. We believe that the need for infrastructure upgrades, environmental management and government outsourcing of support services, among other things, will result in continued opportunities in our core markets. With our track record and our global resources, we believe we are well positioned to compete for projects in these markets.

Continue to pursue our balanced capital allocation strategy

        We intend to pursue a balanced capital allocation strategy that includes acquisitions. This approach has served us well as we have strengthened and diversified our leadership positions geographically, technically and across end markets. We believe that the trend towards consolidation in our industry will continue to produce candidates that align with our acquisition strategy. We also have formed AECOM Capital, an investment fund to invest in public-private partnership and private-sector real estate projects for which we can potentially provide a fully integrated solution that includes equity capital, design, engineering and construction services.

Strengthen and support human capital

        Our experienced employees and management team are our most valuable resources. Attracting and retaining key personnel has been and will remain critical to our success. We will continue to focus on providing our personnel with training and other personal and professional growth opportunities, performance-based incentives, opportunities for stock ownership and other competitive benefits in order to strengthen and support our human capital base. We believe that our employee stock ownership and other programs align the interests of our personnel with those of our clients and stockholders.

Our Business Segments

        The following table sets forth the revenue attributable to our business segments for the periods indicated(1):

	Year Ended September 30, (in millions)
	2012		2011		2010
Professional Technical Services (PTS)	$	7,276.9	$	6,877.1	$	5,393.7
Management Support Services (MSS)		941.3		1,160.3		1,152.1
Total	$	8,218.2	$	8,037.4	$	6,545.8

Our Professional Technical Services Segment

        Our PTS segment comprises a broad array of services, generally provided on a fee-for-service basis. These services include planning, consulting, architectural and engineering design, program management and construction management for industrial, commercial, institutional and government clients worldwide. For each of these services, our technical expertise includes civil, structural, process, mechanical, geotechnical systems and electrical engineering, architectural, landscape and interior design, urban and regional planning, project economics, cost consulting and environmental, health and safety work.

        With our technical and management expertise, we are able to provide our clients with a broad spectrum of services. For example, within our environmental management service offerings, we provide remediation, regulatory compliance planning and management, environmental modeling, environmental impact assessment and environmental permitting for major capital/infrastructure projects.

        Our services may be sequenced over multiple phases. For example, in the area of program management and construction management services, our work for a client may begin with a small consulting or planning contract, and may later develop into an overall management role for the project or a series of projects, which we refer to as a program. Program and construction management contracts typically employ a staff of 10 to more than 100 and, in many cases, operate as an outsourcing arrangement with our staff located at the project site. For example, since 1990, we have been managing renovation work at the Pentagon for the U.S. Department of Defense. Other examples include our construction management services for One World Trade Center, the tallest building in New York, and program management services for Crossrail, the largest addition to the transit system in London and southeast England in half a century.

        We provide the services in our PTS segment both directly and through joint ventures or similar partner arrangements to the following key end markets:

Our Management Support Services Segment

        Through our MSS segment, we offer program and facilities management and maintenance, training, logistics, consulting, technical assistance and systems integration services, primarily for agencies of the U.S. government.

        We provide a wide array of services in our MSS segment, both directly and through joint ventures or similar partner arrangements, including:

        Installation, Operations and Maintenance.    Projects include Department of Defense and Department of Energy installations where we provide comprehensive services for the operation and maintenance of complex government installations, including military bases, test ranges and equipment. We have undertaken assignments in this category in the Middle East and the United States. We also provide services for the operations and maintenance of the Department of Energy's Nevada Test Site.

        Logistics and Field Services.    Projects include logistics support services for a number of Department of Defense agencies and defense prime contractors focused on developing and managing integrated supply and distribution networks. We oversee warehousing, packaging, delivery and traffic management for the distribution of government equipment and materials.

        Training.    Projects include training applications in live, virtual and simulation training environments. We have conducted training at the U.S. Army's Center for Security Training in Maryland for law enforcement and military personnel. We have also supported the training of international police officers and peacekeepers for deployment in various locations around the world in the areas of maintaining electronics and communications equipment.

        Systems Support.    Projects cover a diverse set of operational and support systems for the maintenance, operation and modernization of Department of Defense and Department of Energy installations. Our services in this area range from information technology and communications to life cycle optimization and engineering, including environmental management services. Through projects such as our joint venture operation at the Nevada Test Site, our team is responsible for facility and infrastructure support for critical missions of the U.S. government in its nonproliferation efforts, emergency response readiness, and force support and sustainment. Enterprise network operations and information systems support, including remote location engineering and operation in classified environments, are also specialized services we provide.

Our Clients

        Our clients consist primarily of national, state, regional and local governments, public and private institutions and major corporations. The following table sets forth our total revenue attributable to these categories of clients for each of the periods indicated:

	Year Ended September 30, ($ in millions)
	2012				2011				2010
U.S. Federal Government
PTS	$	548.7	7	%	$	640.8	8	%	$	549.4	8	%
MSS		931.3	11			1,151.4	14			1,152.0	18
U.S. State and Local Governments		1,454.4	18			1,453.3	18			1,362.0	21
Non-U.S. Governments		2,006.4	24			1,931.3	24			1,690.2	26
Subtotal Governments		4,940.8	60			5,176.8	64			4,753.6	73
Private Entities (worldwide)		3,277.4	40			2,860.6	36			1,792.2	27
Total	$	8,218.2	100	%	$	8,037.4	100	%	$	6,545.8	100	%

        Other than the U.S. federal government, no single client accounted for 10% or more of our revenue in any of the past five fiscal years. Approximately 18%, 22% and 26% of our revenue was derived through direct contracts with agencies of the U.S. federal government in the years ended September 30, 2012, 2011 and 2010, respectively. One of these contracts accounted for approximately 4%, 3% and 9% of our revenue in the years ended September 30, 2012, 2011 and 2010, respectively. The work attributed to the U.S. federal government includes our work for the Department of Defense, Department of Energy, Department of Justice and the Department of Homeland Security.

Contracts

        The price provisions of the contracts we undertake can be grouped into two broad categories: cost-reimbursable contracts and fixed-price contracts. The majority of our contracts fall under the category of cost-reimbursable contracts, which we believe are generally less subject to loss than fixed-price contracts. As detailed below, our fixed-price contracts relate primarily to design and construction management contracts where we do not self-perform or take the risk of construction.

Cost-Reimbursable Contracts

        Cost-reimbursable contracts consist of two similar contract types, cost-plus and time and material.

        Cost-Plus.    We enter into two major types of cost-plus contracts:

        Cost-Plus Fixed Fee.    Under cost-plus fixed fee contracts, we charge clients for our costs, including both direct and indirect costs, plus a fixed negotiated fee. The total estimated cost plus the fixed negotiated fee represents the total contract value. We recognize revenue based on the actual labor and other direct costs incurred, plus the portion of the fixed fee earned to date.

        Cost-Plus Fixed Rate.    Under cost-plus fixed rate contracts, we charge clients for our direct and indirect costs based upon a negotiated rate. We recognize revenue based on the actual total costs expended and the applicable fixed rate.

        Certain cost-plus contracts provide for award fees or a penalty based on performance criteria in lieu of a fixed fee or fixed rate. Other contracts include a base fee component plus a performance-based award fee. In addition, we may share award fees with subcontractors. We record accruals for fee-sharing as fees are earned. We generally recognize revenue to the extent of costs actually incurred plus a proportionate

8

amount of the fee expected to be earned. We take the award fee or penalty on contracts into consideration when estimating revenue and profit rates, and record revenue related to the award fees when there is sufficient information to assess anticipated contract performance. On contracts that represent higher than normal risk or technical difficulty, we may defer all award fees until an award fee letter is received. Once an award fee letter is received, the estimated or accrued fees are adjusted to the actual award amount.

        Certain cost-plus contracts provide for incentive fees based on performance against contractual milestones. The amount of the incentive fees varies, depending on whether we achieve above, at, or below target results. We originally recognize revenue on these contracts based upon expected results. These estimates are revised when necessary based upon additional information that becomes available as the contract progresses.

        Time and Material.    Time and material is common for smaller scale engineering and consulting services. Under these types of contracts, we negotiate hourly billing rates and charge our clients based upon actual hours expended on a project. Unlike cost-plus contracts, however, there is no predetermined fee. In addition, any direct project expenditures are passed through to the client and are reimbursed. These contracts may have a fixed-price element in the form of not-to-exceed or guaranteed maximum price provisions.

        For fiscal 2012, 2011 and 2010, cost-reimbursable contracts represented approximately 53%, 54% and 63%, respectively, of our total revenue, consisting of cost-plus contracts and time and material contracts as follows:

	Year Ended September 30,
	2012			2011			2010
Cost-plus contracts		18	%		19	%		24	%
Time and materials contracts		35			35			39
Total		53	%		54	%		63	%

Fixed-Price Contracts

        There are typically two types of fixed-price contracts. The first and more common type, lump-sum, involves performing all of the work under the contract for a specified lump-sum fee. Lump-sum contracts are typically subject to price adjustments if the scope of the project changes or unforeseen conditions arise. In such cases, we will submit formal requests for adjustment of the lump sum via formal change orders or contract amendments. The second type, fixed-unit price, involves performing an estimated number of units of work at an agreed price per unit, with the total payment under the contract determined by the actual number of units delivered.

        Many of our fixed-price contracts are negotiated and arise in the design of projects with a specified scope. Fixed-price contracts often arise in the areas of construction management and design-build services. Construction management services are typically in the form of general administrative oversight (in which we do not assume responsibility for construction means and methods and which is on a cost-reimbursable basis). Under our design-build projects, we are typically responsible for the design of a facility with the fixed contract price negotiated after we have had the opportunity to secure specific bids from various subcontractors (including the contractor that will be primarily responsible for all construction risks) and add a contingency fee.

        We typically attempt to mitigate the risks of fixed-price design-build contracts by contracting to complete the projects based on our design as opposed to a third party's design, by not self-performing construction (except for limited environmental tasks), by not guaranteeing new or untested processes or technologies and by working only with experienced subcontractors with sufficient bonding capacity.

9

        Some of our fixed-price contracts require us to provide performance bonds or parent company guarantees to assure our clients that their project will be completed in accordance with the terms of the contracts. In such cases, we typically require our primary subcontractors to provide similar bonds and guarantees and to be adequately insured, and we flow down the terms and conditions set forth in our agreement on to our subcontractors.

        For fiscal 2012, 2011 and 2010, fixed-price contracts represented approximately 47%, 46% and 37%, respectively, of our total revenue. There may be risks associated with completing these projects profitably if we are not able to perform our professional services for the amount of the fixed fee. However, we attempt to mitigate these risks as described above.

Joint Ventures

        Some of our larger contracts may operate under joint ventures or other arrangements under which we team with other reputable companies, typically companies with which we have worked for many years. This is often done where the scale of the project dictates such an arrangement or when we want to strengthen either our market position or our technical skills.

Backlog

        Backlog is expressed in terms of gross revenue and therefore may include significant estimated amounts of third party, or pass-through costs to subcontractors and other parties. Our total backlog is comprised of contracted backlog and awarded backlog. Our contracted backlog includes revenue we expect to record in the future from signed contracts, and in the case of a public client, where the project has been funded. Our awarded backlog includes revenue we expect to record in the future where we have been awarded the work, but the contractual agreement has not yet been signed. For non-government contracts, our backlog includes future revenue at contract rates, excluding contract renewals or extensions that are at the discretion of the client. For contracts with a not-to-exceed maximum amount, we include revenue from such contracts in backlog to the extent of the remaining estimated amount. We calculate backlog without regard to possible project reductions or expansions or potential cancellations until such changes or cancellations occur. No assurance can be given that we will ultimately realize our full backlog. Our backlog for the year ended September 30, 2012, increased $0.4 billion, or 3%, to $16.0 billion as compared to $15.6 billion for the corresponding period last year.

        The following summarizes contracted and awarded backlog, excluding backlog as of September 30, 2012, 2011 and 2010 related to businesses which we divested, as discussed in Note 5 in the notes to our consolidated financial statements (in billions):

Competition

        The professional technical and management support services markets we serve are highly fragmented and we compete with a large number of regional, national and international companies. Certain of these competitors have greater financial and other resources than we do. Others are smaller and more specialized, and concentrate their resources in particular areas of expertise. The extent of our competition varies according to the particular markets and geographic area. The degree and type of competition we face is also influenced by the type and scope of a particular project. Our clients make competitive determinations based upon qualifications, experience, performance, reputation, technology, customer relationships and ability to provide the relevant services in a timely, safe and cost-efficient manner.

Seasonality

        We experience seasonal trends in our business. Our revenue is typically higher in the last half of the fiscal year. The fourth quarter of our fiscal year (July 1 to September 30) is typically our strongest quarter. We find that the U.S. federal government tends to authorize more work during the period preceding the end of our fiscal year, September 30. In addition, many U.S. state governments with fiscal years ending on June 30 tend to accelerate spending during their first quarter, when new funding becomes available. Further, our construction management revenue typically increases during the high construction season of the summer months. Within the United States, as well as other parts of the world, our business generally benefits from milder weather conditions in our fiscal fourth quarter, which allows for more productivity from our on-site civil services. Our construction and project management services also typically expand during the high construction season of the summer months. The first quarter of our fiscal year (October 1 to December 31) is typically our weakest quarter. The harsher weather conditions impact our ability to complete work in parts of North America and the holiday season schedule affects our productivity during this period. For these reasons, coupled with the number and significance of client contracts commenced and completed during a particular period, as well as the timing of expenses incurred for corporate initiatives, it is not unusual for us to experience seasonal changes or fluctuations in our quarterly operating results.

Insurance and Risk Management

        We maintain insurance covering professional liability and claims involving bodily injury and property damage. We consider our present limits of coverage, deductibles, and reserves to be adequate. Wherever possible, we endeavor to eliminate or reduce the risk of loss on a project through the use of quality assurance/control, risk management, workplace safety and similar methods. A majority of our operating subsidiaries are quality certified under ISO 9001:2000 or an equivalent standard, and we plan to continue to obtain certification where applicable. ISO 9001:2000 refers to international quality standards developed by the International Organization for Standardization, or ISO.

        Risk management is an integral part of our project management approach and our project execution process. We have an Office of Risk Management that reviews and oversees the risk profile of our operations. Also, pursuant to our internal delegations of authority, we have a formal process whereby a group of senior members of our risk management team evaluate risk through internal risk analyses of higher-risk projects, contracts or other business decisions.

Regulation

        We are regulated in a number of fields in which we operate. In the United States, we deal with numerous U.S. government agencies and entities, including branches of the U.S. military, the Department of Defense, the Department of Energy, intelligence agencies and the Nuclear Regulatory Commission. When working with these and other U.S. government agencies and entities, we must comply with laws and regulations relating to the formation, administration and performance of contracts. These laws and regulations, among other things:

•

require certification and disclosure of all cost or pricing data in connection with various contract negotiations;

•

impose procurement regulations that define allowable and unallowable costs and otherwise govern our right to reimbursement under various cost-based U.S. government contracts; and

•

restrict the use and dissemination of information classified for national security purposes and the exportation of certain products and technical data.

        Internationally, we are subject to various government laws and regulations (including the U.S. Foreign Corrupt Practices Act, Arms Export Control Act, Department of Commerce Export and Anti Boycott Regulations, Proceeds of Crime Act, UK Bribery Act and other similar non-U.S. laws and regulations), local government regulations and procurement policies and practices and varying currency, political and economic risks.

        To help ensure compliance with these laws and regulations, all of our employees are required to complete tailored ethics and other compliance training relevant to their position and our operations.

        Compliance with federal, state, local and foreign laws enacted for the protection of the environment has to date had no significant effect on our capital expenditures, earnings, or competitive position. In the future, compliance with environmental laws could materially adversely affect us. We will continue to monitor the impact of such laws on our business and will develop appropriate compliance programs.

Personnel

        Our principal asset is our employees. A large percentage of our employees have technical and professional backgrounds and undergraduate and/or advanced degrees. We believe that we attract and retain talented employees by offering them the opportunity to work on highly visible and technically challenging projects in a stable work environment. The tables below identify our personnel by segment and geographic region.

ITEM 1A.    RISK FACTORS

We operate in a changing environment that involves numerous known and unknown risks and uncertainties that could materially adversely affect our operations. The risks described below highlight some of the factors that have affected, and in the future could affect our operations. Additional risks we do not yet know of or that we currently think are immaterial may also affect our business operations. If any of the events or circumstances described in the following risks actually occur, our business, financial condition or results of operations could be materially adversely affected.

We depend on long-term government contracts, some of which are only funded on an annual basis. If appropriations for funding are not made in subsequent years of a multiple-year contract, we may not be able to realize all of our anticipated revenue and profits from that project.

        A substantial majority of our revenue is derived from contracts with agencies and departments of national, state and local governments. During fiscal 2012, 2011 and 2010, approximately 60%, 64% and 73%, respectively, of our revenue was derived from contracts with government entities.

        Most government contracts are subject to the government's budgetary approval process. Legislatures typically appropriate funds for a given program on a year-by-year basis, even though contract performance may take more than one year. As a result, at the beginning of a program, the related contract is only partially funded, and additional funding is normally committed only as appropriations are made in each subsequent fiscal year. These appropriations, and the timing of payment of appropriated amounts, may be influenced by, among other things, the state of the economy, competing priorities for appropriation, changes in administration or control of legislatures and the timing and amount of tax receipts and the overall level of government expenditures. If appropriations are not made in subsequent years on our government contracts, then we will not realize all of our potential revenue and profit from that contract.

The Budget Control Act of 2011 could significantly reduce U.S. government spending for the services we provide.

        Under the Budget Control Act of 2011, an automatic sequestration process, or across-the-board budget cuts, was triggered when the Joint Select Committee on Deficit Reduction, a committee of twelve members of Congress, failed to agree on a deficit reduction plan for the U.S. federal budget. The sequestration is scheduled to begin on January 2, 2013, absent legislative or other remedial action, and requires $1.2 trillion in reduced U.S. federal government spending over a ten-year period. Any significant reduction in federal government spending could reduce demand for our services, cancel or delay federal projects, and result in the closure of federal facilities, and significant personnel reductions, which could have a material adverse effect on our results of operation and financial condition.

Governmental agencies may modify, curtail or terminate our contracts at any time prior to their completion and, if we do not replace them, we may suffer a decline in revenue.

        Most government contracts may be modified, curtailed or terminated by the government either at its discretion or upon the default of the contractor. If the government terminates a contract at its discretion, then we typically are able to recover only costs incurred or committed, settlement expenses and profit on work completed prior to termination, which could prevent us from recognizing all of our potential revenue and profits from that contract. In addition, the U.S. government has announced its intention to scale back outsourcing of services in favor of "insourcing" jobs to its employees, which could reduce the number of contracts awarded to us. The adoption of similar practices by other government entities could also adversely affect our revenues. If a government terminates a contract due to our default, we could be liable for excess costs incurred by the government in obtaining services from another source.

14

Demand for our services is cyclical and may be vulnerable to sudden economic downturns and reductions in government and private industry spending. If economic conditions remain weak and decline further, our revenue and profitability could be adversely affected.

        Demand for our services is cyclical and may be vulnerable to sudden economic downturns and reductions in government and private industry spending, which may result in clients delaying, curtailing or canceling proposed and existing projects. Economic conditions in the U.S. and a number of other countries and regions, including the United Kingdom, are weak and may remain difficult for the foreseeable future. If global economic and financial market conditions remain weak and/or decline further, some of our clients may face considerable budget shortfalls that may limit their overall demand for our services. In addition, our clients may find it more difficult to raise capital in the future to fund their projects due to uncertainty in the municipal and general credit markets. Also, the global demand for commodities has increased raw material costs, which will cause our clients' projects to increase in overall cost and may result in the more rapid depletion of the funds that are available to our clients to spend on projects.

        Where economies are weakening, our clients may demand more favorable pricing or other terms while their ability to pay our invoices or to pay them in a timely manner may be adversely affected. Our government clients may face budget deficits that prohibit them from funding proposed and existing projects. If economic conditions remain uncertain and/or weaken and/or government spending is reduced, our revenue and profitability could be adversely affected.

Our contracts with governmental agencies are subject to audit, which could result in adjustments to reimbursable contract costs or, if we are charged with wrongdoing, possible temporary or permanent suspension from participating in government programs.

        Our books and records are subject to audit by the various governmental agencies we serve and their representatives. These audits can result in adjustments to the amount of contract costs we believe are reimbursable by the agencies and the amount of our overhead costs allocated to the agencies. For example, as discussed elsewhere in this report, the U.S. Defense Contract Audit Agency (DCAA) issued a DCAA Form 1 questioning costs incurred during fiscal 2009 by Global Linguists Solutions, a joint venture that includes McNeil Technologies, Inc., in the performance of U.S. government contracts. In addition, the U.S. Attorney's Office (USAO) has informed us that the USAO and the U.S. Environmental Protection Agency are investigating potential criminal charges relating to one of our subsidiaries' projects in the state of Hawaii. If such matters are not resolved in our favor, they could have a material adverse effect on our business. In addition, if one of our subsidiaries is charged with wrongdoing as a result of an audit, that subsidiary, and possibly our company as a whole, could be temporarily suspended or could be prohibited from bidding on and receiving future government contracts for a period of time. Furthermore, as a government contractor, we are subject to an increased risk of investigations, criminal prosecution, civil fraud actions, whistleblower lawsuits and other legal actions and liabilities to which purely private sector companies are not, the results of which could materially adversely impact our business.

Our operations worldwide expose us to legal, political and economic risks in different countries as well as currency exchange rate fluctuations that could harm our business and financial results.

        During fiscal 2012, revenue attributable to our services provided outside of the United States to non-U.S. clients was approximately 42% of our total revenue. There are risks inherent in doing business internationally, including:

•

imposition of governmental controls and changes in laws, regulations or policies;

•

political and economic instability;

•

civil unrest, acts of terrorism, force majeure, war, or other armed conflict;

•

changes in U.S. and other national government trade policies affecting the markets for our services;

15

•

changes in regulatory practices, tariffs and taxes;

•

potential non-compliance with a wide variety of laws and regulations, including anti-corruption, export control and anti-boycott laws and similar non-U.S. laws and regulations;

•

changes in labor conditions;

•

logistical and communication challenges; and

•

currency exchange rate fluctuations, devaluations and other conversion restrictions.

        Any of these factors could have a material adverse effect on our business, results of operations or financial condition.

Political, economic and military conditions in the Middle East, Africa and other regions could negatively impact our business.

        Last year, civil unrest, which initially began in Tunisia and Egypt, spread to other areas in the Middle East and beyond. Due to the civil unrest in Libya in February 2011, we ceased providing services as the program manager for the Libyan Housing and Infrastructure Board's program to modernize the country's infrastructure. We cannot currently determine when or if we will resume services. This business disruption resulted in an operating loss, primarily due to demobilization and shutdown costs, and certain asset write-downs. If civil unrest were to disrupt our business in other countries in the Middle East or other regions in which we operate, and particularly if political activities were to result in prolonged unrest or civil war, our financial condition could be adversely affected.

We operate in many different jurisdictions and we could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar worldwide anti-corruption laws.

        The U.S. Foreign Corrupt Practices Act (FCPA) and similar worldwide anti-corruption laws, including the U.K. Bribery Act of 2010, generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. Our internal policies mandate compliance with these anti-corruption laws. We operate in many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-corruption laws may conflict with local customs and practices. Despite our training and compliance programs, we cannot assure that our internal control policies and procedures always will protect us from reckless or criminal acts committed by our employees or agents. Our continued expansion outside the U.S., including in developing countries, could increase the risk of such violations in the future. In addition, from time to time, government investigations of corruption in construction-related industries affect us and our peers. Violations of these laws, or allegations of such violations, could disrupt our business and result in a material adverse effect on our results of operations or financial condition.

We work in international locations where there are high security risks, which could result in harm to our employees and contractors or material costs to us.

        Some of our services are performed in high-risk locations, such as Afghanistan, and, until recently, Iraq and Libya, where the country or location is suffering from political, social or economic problems, or war or civil unrest. In those locations where we have employees or operations, we may incur material costs to maintain the safety of our personnel. Despite these precautions, the safety of our personnel in these locations may continue to be at risk. Acts of terrorism and threats of armed conflicts in or around various areas in which we operate could limit or disrupt markets and our operations, including disruptions resulting from the evacuation of personnel, cancellation of contracts, or the loss of key employees, contractors or assets. For example, as discussed above, we incurred losses related to demobilization and shutdown costs related to the cessation of our operations in Libya due to ongoing civil unrests.

16

Our business and operating results could be adversely affected by losses under fixed-price contracts.

        Fixed-price contracts require us to either perform all work under the contract for a specified lump-sum or to perform an estimated number of units of work at an agreed price per unit, with the total payment determined by the actual number of units performed. In fiscal 2012, approximately 47% of our revenue was recognized under fixed-price contracts. Fixed-price contracts are more frequently used outside of the United States and, thus, the exposures resulting from fixed-price contracts may increase as we increase our business operations outside of the United States. Fixed-price contracts expose us to a number of risks not inherent in cost-plus and time and material contracts, including underestimation of costs, ambiguities in specifications, unforeseen costs or difficulties, problems with new technologies, delays beyond our control, failures of subcontractors to perform and economic or other changes that may occur during the contract period. Losses under fixed-price contracts could be substantial and adversely impact our results of operations.

We conduct a portion of our operations through joint venture entities, over which we may have limited control.

        Approximately 13% of our fiscal 2012 revenue was derived from our operations through joint ventures or similar partnership arrangements, where control may be shared with unaffiliated third parties. As with most joint venture arrangements, differences in views among the joint venture participants may result in delayed decisions or disputes. We also cannot control the actions of our joint venture partners, and we typically have joint and several liability with our joint venture partners under the applicable contracts for joint venture projects. These factors could potentially adversely impact the business and operations of a joint venture and, in turn, our business and operations.

        Operating through joint ventures in which we are minority holders results in us having limited control over many decisions made with respect to projects and internal controls relating to projects. Of the joint ventures noted above, approximately 7% of our fiscal 2012 revenue was derived from our unconsolidated joint ventures where we generally do not have control of the joint venture. These joint ventures may not be subject to the same requirements regarding internal controls and internal control over financial reporting that we follow. As a result, internal control problems may arise with respect to these joint ventures, which could have a material adverse effect on our financial condition and results of operations.

Misconduct by our employees or consultants or our failure to comply with laws or regulations applicable to our business could cause us to lose customers or lose our ability to contract with government agencies.

        As a government contractor, misconduct, fraud or other improper activities caused by our employees' or consultants' failure to comply with laws or regulations could have a significant negative impact on our business and reputation. Such misconduct could include the failure to comply with federal procurement regulations, regulations regarding the protection of sensitive government information, legislation regarding the pricing of labor and other costs in government contracts, regulations on lobbying or similar activities, and anti-corruption, export control and other applicable laws or regulations. Our failure to comply with applicable laws or regulations, misconduct by any of our employees or consultants or our failure to make timely and accurate certifications to government agencies regarding misconduct or potential misconduct could subject us to fines and penalties, loss of government granted eligibility, cancellation of contracts and suspension or debarment from contracting with government agencies, any of which may adversely affect our business.

Our defined benefit plans have significant deficits that could grow in the future and cause us to incur additional costs.

        We have defined benefit pension plans for employees in the United States, United Kingdom, Australia, Ireland, and Canada. At September 30, 2012, our defined benefit pension plans had an aggregate deficit (the excess of projected benefit obligations over the fair value of plan assets) of

17

approximately $192.2 million. In the future, our pension deficits may increase or decrease depending on changes in the levels of interest rates, pension plan performance and other factors. Because the current economic environment has resulted in declining investment returns and interest rates, we may be required to make additional cash contributions to our pension plans and recognize further increases in our net pension cost to satisfy our funding requirements. If we are forced or elect to make up all or a portion of the deficit for unfunded benefit plans, our results of operations could be materially and adversely affected.

New legal requirements could adversely affect our operating results.

        Our business and results of operations could be adversely affected by the passage of U.S. health care reform, climate change, and other environmental legislation and regulations. Currently, we are assessing the impact that health care reform could have on our employer-sponsored medical plans. Growing concerns about climate change may result in the imposition of additional environmental regulations. For example, legislation, international protocols, regulation or other restrictions on emissions could increase the costs of projects for our clients or, in some cases, prevent a project from going forward, thereby potentially reducing the need for our services. However, these changes could also increase the pace of development of other projects, which could have a positive impact on our business. We cannot predict when or whether any of these various proposals may be enacted or what their effect will be on us or on our customers.

Failure to successfully execute our acquisition strategy may inhibit our growth.

        We have grown in part as a result of our acquisitions over the last several years, and we expect continued growth in the form of additional acquisitions and expansion into new markets. If we are unable to pursue suitable acquisition opportunities, as a result of global economic uncertainty or other factors, our growth may be inhibited. We cannot assure that suitable acquisitions or investment opportunities will continue to be identified or that any of these transactions can be consummated on favorable terms or at all. Any future acquisitions will involve various inherent risks, such as:

•

our ability to accurately assess the value, strengths, weaknesses, liabilities and potential profitability of acquisition candidates;

•

the potential loss of key personnel of an acquired business;

•

increased burdens on our staff and on our administrative, internal control and operating systems, which may hinder our legal and regulatory compliance activities;

•

liabilities related to pre-acquisition activities of an acquired business and the burdens on our staff and resources to comply with, conduct or resolve investigations into such activities;

•

post-acquisition integration challenges; and

•

post-acquisition deterioration in an acquired business that could result in lower or negative earnings contribution and/or goodwill impairment charges.

        Furthermore, during the acquisition process and thereafter, our management may need to assume significant transaction-related responsibilities, which may cause them to divert their attention from our existing operations. If our management is unable to successfully integrate acquired companies or implement our growth strategy, our operating results could be harmed. Moreover, we cannot assure that we will continue to successfully expand or that growth or expansion will result in profitability.

Our ability to grow and to compete in our industry will be harmed if we do not retain the continued services of our key technical and management personnel and identify, hire, and retain additional qualified personnel.

        There is strong competition for qualified technical and management personnel in the sectors in which we compete. We may not be able to continue to attract and retain qualified technical and management

18

personnel, such as engineers, architects and project managers, who are necessary for the development of our business or to replace qualified personnel. Our planned growth may place increased demands on our resources and will likely require the addition of technical and management personnel and the development of additional expertise by existing personnel. Also, some of our personnel hold government granted eligibility that may be required to obtain certain government projects. If we were to lose some or all of these personnel, they would be difficult to replace. Loss of the services of, or failure to recruit, key technical and management personnel could limit our ability to successfully complete existing projects and compete for new projects.

Our revenue and growth prospects may be harmed if we or our employees are unable to obtain government granted eligibility or other qualifications we and they need to perform services for our customers.

        A number of government programs require contractors to have certain kinds of government granted eligibility. Depending on the project, eligibility can be difficult and time-consuming to obtain. If we or our employees are unable to obtain or retain the necessary eligibility, we may not be able to win new business, and our existing customers could terminate their contracts with us or decide not to renew them. To the extent we cannot obtain or maintain the required security clearances for our employees working on a particular contract, we may not derive the revenue or profit anticipated from such contract.

Our industry is highly competitive and we may be unable to compete effectively, which could result in reduced revenue, profitability and market share.

        We are engaged in a highly competitive business. The professional technical and management support services markets we serve are highly fragmented and we compete with a large number of regional, national and international companies. Certain of these competitors have greater financial and other resources than we do. Others are smaller and more specialized, and concentrate their resources in particular areas of expertise. The extent of our competition varies according to the particular markets and geographic area. The degree and type of competition we face is also influenced by the type and scope of a particular project. Our clients make competitive determinations based upon qualifications, experience, performance, reputation, technology, customer relationships and ability to provide the relevant services in a timely, safe and cost-efficient manner. Increased competition may result in our inability to win bids for future projects and loss of revenue, profitability and market share.

If we extend a significant portion of our credit to clients in a specific geographic area or industry, we may experience disproportionately high levels of collection risk and nonpayment if those clients are adversely affected by factors particular to their geographic area or industry.

        Our clients include public and private entities that have been, and may continue to be, negatively impacted by the changing landscape in the global economy. While outside of the U.S. Federal Government no one client accounts for over 10% of our revenue, we face collection risk as a normal part of our business where we perform services and subsequently bill our clients for such services. In the event that we have concentrated credit risk from clients in a specific geographic area or industry, continuing negative trends or a worsening in the financial condition of that specific geographic area or industry could make us susceptible to disproportionately high levels of default by those clients. Such defaults could materially adversely impact our revenues and our results of operations.

Our services expose us to significant risks of liability and our insurance policies may not provide adequate coverage.

        Our services involve significant risks of professional and other liabilities that may substantially exceed the fees that we derive from our services. In addition, we sometimes contractually assume liability under indemnification agreements. We cannot predict the magnitude of potential liabilities from the operation of our business.

19

        Our professional liability policies cover only claims made during the term of the policy. Additionally, our insurance policies may not protect us against potential liability due to various exclusions in the policies and self-insured retention amounts. Partially or completely uninsured claims, if successful and of significant magnitude, could have a material adverse effect on our business.

Our backlog of uncompleted projects under contract is subject to unexpected adjustments and cancellations and, thus, may not accurately reflect future revenue and profits.

        At September 30, 2012, our contracted backlog was approximately $8.5 billion and our awarded backlog was approximately $7.5 billion for a total backlog of $16.0 billion. Our contracted backlog includes revenue we expect to record in the future from signed contracts and, in the case of a public sector client, where the project has been funded. Our awarded backlog includes revenue we expect to record in the future where we have been awarded the work, but the contractual agreement has not yet been signed. We cannot guarantee that future revenue will be realized from either category of backlog or, if realized, will result in profits. Many projects may remain in our backlog for an extended period of time because of the size or long-term nature of the contract. In addition, from time to time, projects are delayed, scaled back or cancelled. These types of backlog reductions adversely affect the revenue and profits that we ultimately receive from contracts reflected in our backlog.

We have submitted claims to clients for work we performed beyond the initial scope of some of our contracts. If these clients do not approve these claims, our results of operations could be adversely impacted.

        We typically have pending claims submitted under some of our contracts for payment of work performed beyond the initial contractual requirements for which we have already recorded revenue. In general, we cannot guarantee that such claims will be approved in whole, in part, or at all. If these claims are not approved, our revenue may be reduced in future periods.

In conducting our business, we depend on other contractors and subcontractors. If these parties fail to satisfy their obligations to us or other parties or if we are unable to maintain these relationships, our revenue, profitability and growth prospects could be adversely affected.

        We depend on contractors and subcontractors in conducting our business. There is a risk that we may have disputes with our subcontractors arising from, among other things, the quality and timeliness of work performed by the subcontractor, customer concerns about the subcontractor, or our failure to extend existing task orders or issue new task orders under a subcontract. In addition, if any of our subcontractors fail to deliver on a timely basis the agreed-upon supplies and/or perform the agreed-upon services, our ability to fulfill our obligations as a prime contractor may be jeopardized and/or we could be held responsible for such failures.

        We also rely on relationships with other contractors when we act as their subcontractor or joint venture partner. Our future revenue and growth prospects could be adversely affected if other contractors eliminate or reduce their subcontracts or joint venture relationships with us, or if a government agency terminates or reduces these other contractors' programs, does not award them new contracts or refuses to pay under a contract. In addition, due to "pay when paid" provisions that are common in subcontracts in certain countries, including the U.S., we could experience delays in receiving payment if the prime contractor experiences payment delays.

If clients use our reports or other work product without appropriate disclaimers or in a misleading or incomplete manner, our business could be adversely affected.

        The reports and other work product we produce for clients sometimes include projections, forecasts and other forward-looking statements. Such information by its nature is subject to numerous risks and uncertainties, any of which could cause the information produced by us to ultimately prove inaccurate.

20

While we include appropriate disclaimers in the reports that we prepare for our clients, once we produce such written work product, we have no ability to control the manner in which our clients use such information. As a result, if our clients reproduce such information to solicit funds from investors for projects without appropriate disclaimers and the information proves to be incorrect, or if our clients reproduce such information for potential investors in a misleading or incomplete manner, our clients or such investors may threaten to or file suit against us for, among other things, securities law violations. If we were found to be liable for any claims related to our client work product, our business could be adversely affected.

Our quarterly operating results may fluctuate significantly.

        We experience seasonal trends in our business with our revenue typically being higher in the last half of the fiscal year. Our fourth quarter (July 1 to September 30) typically is our strongest quarter, and our first quarter is typically our weakest quarter. Our quarterly revenue, expenses and operating results may fluctuate significantly because of a number of factors, including:

•

the spending cycle of our public sector clients;

•

employee hiring and utilization rates;

•

the number and significance of client engagements commenced and completed during a quarter;

•

the ability of clients to terminate engagements without penalties;

•

the ability of our project managers to accurately estimate the percentage of the project completed;

•

delays incurred as a result of weather conditions;

•

delays incurred in connection with an engagement;

•

the size and scope of engagements;

•

the timing and magnitude of expenses incurred for, or savings realized from, corporate initiatives;

•

changes in foreign currency rates;

•

the seasonality of our business;

•

the impairment of goodwill or other intangible assets; and

•

general economic and political conditions.

        Variations in any of these factors could cause significant fluctuations in our operating results from quarter to quarter.

An impairment charge of goodwill could have a material adverse impact on our financial condition and results of operations.

        Because we have grown in part through acquisitions, goodwill and intangible assets-net represent a substantial portion of our assets. Goodwill and intangible assets-net were $1.9 billion as of September 30, 2012. Under accounting principles generally accepted in the United States, we are required to test goodwill carried in our Consolidated Balance Sheets for possible impairment on an annual basis based upon a fair value approach and whenever events occur that indicate impairment could exist. These events or circumstances could include a significant change in the business climate, including a significant sustained decline in a reporting unit's market value, legal factors, operating performance indicators, competition, sale or disposition of a significant portion of our business, a significant sustained decline in our market capitalization and other factors. In connection with our annual goodwill impairment testing for fiscal 2012, we recorded an impairment charge of $336 million due to market conditions and business trends within the Europe, Middle East, and Africa (EMEA) and MSS reporting units.

21

        If the fair value of our reporting units is less than their carrying value, we could be required to record an additional impairment charge. In addition, if a decrease in our stock price and market capitalization continues over a sustained period, we would have to record an impairment charge in the future. The amount of any impairment could be significant and could have a material adverse impact on our financial condition and results of operations for the period in which the charge is taken.

If we are unable to continue to access credit on acceptable terms, our business may be adversely affected.

        The state of the global credit markets could make it more difficult for us to access funds, refinance our existing indebtedness, enter into agreements for new indebtedness, replace our existing credit agreement on or before its expiration in 2016 or obtain funding through the issuance of our securities. We use credit facilities to support our working capital and acquisition needs. There is no guarantee that we can continue to renew our credit facility on terms as favorable as those in our existing credit facility and, if we are unable to do so, our costs of borrowing and our business may be adversely affected.

Our debt agreements contain restrictive covenants and financial ratio tests that restrict or prohibit our ability to engage in or enter into a variety of transactions. If we fail to comply with these covenants or tests, our indebtedness under these agreements could become accelerated, which could adversely affect us.

        Our debt agreements, including our senior credit facility and the agreement governing our senior notes, contain various covenants that may have the effect of limiting, among other things, our ability and the ability of certain of our subsidiaries to: merge with other entities, enter into a transaction resulting in a change in control, create new liens, incur additional indebtedness, sell assets outside of the ordinary course of business, enter into transactions with affiliates (other than subsidiaries) or substantially change the general nature of our and our subsidiaries' business, taken as a whole, and, in the case of our senior credit facility, make certain investments, enter into restrictive agreements, or make certain dividends or other distributions. These restrictions could limit our ability to take advantage of financing, merger, acquisition or other opportunities, to fund our business operations or to fully implement our current and future operating strategies.

        All of our debt agreements relating to our unsecured revolving credit facility and unsecured term credit agreements require us to maintain compliance with a maximum consolidated leverage ratio at the end of any fiscal quarter. The agreement governing our senior notes also requires us to maintain a net worth above a calculated threshold. As of September 30, 2012, our consolidated leverage ratio was 2.15, which did not exceed our most restrictive maximum consolidated leverage ratio of 3.0. As of September 30, 2012, our net worth was $2.2 billion, which exceeds the calculated threshold of $1.5 billion. Our ability to continue to meet these financial ratios and tests will be dependent upon our future performance and may be affected by events beyond our control (including factors discussed in this "Risk Factors" section). If we fail to satisfy these requirements, our indebtedness under these agreements could become accelerated and payable at a time when we are unable to pay them. This would adversely affect our ability to implement our operating strategies and would have a material adverse effect on our financial condition.

Systems and information technology interruption could adversely impact our ability to operate.

        We rely heavily on computer, information and communications technology and related systems in order to properly operate. From time to time, we experience occasional system interruptions and delays. If we are unable to continually add software and hardware, effectively upgrade our systems and network infrastructure and take other steps to improve the efficiency of and protect our systems, the operation of our systems could be interrupted or delayed. Our computer and communications systems and operations could be damaged or interrupted by natural disasters, telecommunications failures, acts of war or terrorism and similar events or disruptions. Any of these or other events could cause system interruption, delays and loss of critical data, or delay or prevent operations, and adversely affect our operating results.

22

        In addition, we face the threat to our computer systems of unauthorized access, computer hackers, computer viruses, malicious code, organized cyber attacks and other security problems and system disruptions, including possible unauthorized access to our and our clients' proprietary or classified information. We rely on industry-accepted security measures and technology to securely maintain all confidential and proprietary information on our information systems . We have devoted and will continue to devote significant resources to the security of our computer systems, but they may still be vulnerable to these threats. A user who circumvents security measures could misappropriate confidential or proprietary information or cause interruptions or malfunctions in operations. As a result, we may be required to expend significant resources to protect against the threat of these system disruptions and security breaches or to alleviate problems caused by these disruptions and breaches. Any of these events could damage our reputation and have a material adverse effect on our business, financial condition, results of operations and cash flows.

Failure to adequately protect, maintain, or enforce our rights in our intellectual property may adversely limit our competitive position.

        Our success depends, in part, upon our ability to protect our intellectual property. We rely on a combination of intellectual property policies and other contractual arrangements to protect much of our intellectual property where we do not believe that trademark, patent or copyright protection is appropriate or obtainable. Trade secrets are generally difficult to protect. Although our employees are subject to confidentiality obligations, this protection may be inadequate to deter or prevent misappropriation of our confidential information and/or the infringement of our patents and copyrights. Further, we may be unable to detect unauthorized use of our intellectual property or otherwise take appropriate steps to enforce our rights. Failure to adequately protect, maintain, or enforce our intellectual property rights may adversely limit our competitive position.

Our charter documents contain provisions that may delay, defer or prevent a change of control.

        Provisions of our certificate of incorporation and bylaws could make it more difficult for a third party to acquire control of us, even if the change in control would be beneficial to stockholders. These provisions include the following:

•

division of our Board of Directors into three classes, with each class serving a staggered three-year term;

•

removal of directors for cause only;

•

ability of our Board of Directors to authorize the issuance of preferred stock in series without stockholder approval;

•

two-thirds stockholder vote requirement to approve specified business combinations, which include a sale of substantially all of our assets;

•

vesting of exclusive authority in our Board of Directors to determine the size of the board (subject to limited exceptions) and to fill vacancies;

•

advance notice requirements for stockholder proposals and nominations for election to our Board of Directors; and

•

prohibitions on our stockholders from acting by written consent and limitations on calling special meetings.

ITEM 1B.    UNRESOLVED STAFF COMMENTS

        None.

ITEM 2.    PROPERTIES

        Our corporate offices are located in approximately 78,000 square feet of space at 555 and 515 South Flower Street, Los Angeles, California. Our other offices consist of an aggregate of approximately 7.7 million square feet worldwide. We also maintain smaller administrative or project offices. Virtually all of our offices are leased. See Note 14 in the notes to our consolidated financial statements for information regarding our lease obligations. We believe our current properties are adequate for our business operations and are not currently underutilized. We may add additional facilities from time to time in the future as the need arises.

ITEM 3.    LEGAL PROCEEDINGS

        As a government contractor, we are subject to various laws and regulations that are more restrictive than those applicable to non-government contractors. Intense government scrutiny of contractors' compliance with those laws and regulations through audits and investigations is inherent in government contracting and, from time to time, we receive inquiries, subpoenas, and similar demands related to our ongoing business with government entities. Violations can result in civil or criminal liability as well as suspension or debarment from eligibility for awards of new government contracts or option renewals.

        We are involved in various investigations, claims and lawsuits in the normal conduct of our business. Although the outcome of our legal proceedings cannot be predicted with certainty and no assurances can be provided, in the opinion of our management, based upon current information and discussions with counsel, none of the investigations, claims and lawsuits in which we are involved is expected to have a material adverse effect on our consolidated financial position, results of operations, cash flows or our ability to conduct business. See Note 20, "Commitments and Contingencies," of this report for a discussion of certain matters to which we are a party. From time to time, we establish reserves for litigation when we consider it probable that a loss will occur.

ITEM 4.    MINE AND SAFETY DISCLOSURES

ITEM 5.    MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

        Our common stock is listed on the New York Stock Exchange (NYSE). According to the records of our transfer agent, there were 2,170 stockholders of record as of November 7, 2012. The following table sets forth the low and high closing sales prices of a share of our common stock during each of the fiscal quarters presented, based upon quotations on the NYSE consolidated reporting system:

	Low Sales Price ($)		High Sales Price ($)
Fiscal 2012:
First quarter		16.84		21.62
Second quarter		20.80		24.06
Third quarter		14.91		22.68
Fourth quarter		15.29		21.62

Second quarter		26.15		29.93
Third quarter		25.82		28.67
Fourth quarter		17.67		28.18

        Our policy is to use cash flow from operations to fund future growth and pay down debt. Accordingly, we have not paid a cash dividend since our inception and we currently have no plans to pay cash dividends in the foreseeable future. Additionally, our term credit agreement and revolving credit facility restrict our ability to pay cash dividends. Our debt agreements do not permit us to pay cash dividends unless at the time of and immediately after giving effect to the dividend, (a) there is no default or event of default and (b) the leverage ratio (as defined in the debt agreements) is less than 3.00 to 1.00.

Performance Measurement Comparison(1)

        The following chart compares the percentage change of AECOM stock (ACM) with that of the S&P MidCap 400 and the S&P 1500 SuperComposite Engineering and Construction indices from October 1, 2007 to September 30, 2012. We believe the S&P MidCap 400, on which we are listed, is an appropriate independent broad market index, since it measures the performance of similar mid-sized companies in numerous sectors. In addition, we believe the S&P 1500 SuperComposite Engineering and Construction Index is an appropriate published industry index since it measures the performance of engineering and construction companies.

Stock Repurchase Program

        In August 2011, our Board of Directors authorized a stock repurchase program, pursuant to which we could purchase up to $200 million of our common stock. We completed the initial authorization to purchase $200 million of our common stock during the quarter ended June 30, 2012.

        In August 2012, our Board of Directors authorized an additional $300 million to purchase our common stock under the stock repurchase program. Share repurchases under this program may be made through open market purchases, unsolicited or solicited privately negotiated transactions or other methods, including pursuant to a Rule 10b5-1 plan. The timing, nature and amount of purchases depend on a variety of factors, including market conditions and the volume limit defined by Rule 10b-18. Repurchased shares are retired, but remain authorized for registration and issuance in the future.

        A summary of the repurchase activity for the three months ended September 30, 2012 is as follows:

Period	Total Number of Shares Purchased		Average Price Paid Per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs		Maximum Dollar Value that May Yet Be Purchased Under the Plans or Programs

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion in conjunction with our consolidated financial statements and the related notes included in this report. In addition to historical consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. You should not place undue reliance on these forward-looking statements. Our actual results could differ materially. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this report, particularly in "Risk Factors."

Overview

        We are a leading global provider of professional technical and management support services for public and private clients around the world. We provide our services in a broad range of end markets through a network of approximately 46,800 employees.

        Our business focuses primarily on providing fee-based professional technical and support services and therefore our business is labor and not capital intensive. We derive income from our ability to generate revenue and collect cash from our clients through the billing of our employees' time spent on client projects and our ability to manage our costs. We report our business through two segments: Professional Technical Services (PTS) and Management Support Services (MSS).

        Our PTS segment delivers planning, consulting, architectural and engineering design, and program and construction management services to institutional, commercial and government clients worldwide in end markets such as transportation, facilities, environmental and energy markets. PTS revenue is primarily derived from fees from services that we provide, as opposed to pass-through fees from subcontractors and other direct costs. Our PTS segment contributed $7.3 billion, or 89%, of our fiscal 2012 revenue.

29

        Our MSS segment provides facilities management and maintenance, training, logistics, consulting, technical assistance and systems integration services, primarily for agencies of the U.S. government. MSS revenue typically includes a significant amount of pass-through fees from subcontractors and other direct costs. Our MSS segment contributed $941 million, or 11%, of our fiscal 2012 revenue.

        Our revenue is dependent on our ability to attract and retain qualified and productive employees, identify business opportunities, integrate and maximize the value of our recent acquisitions, allocate our labor resources to profitable and high growth markets, secure new contracts and renew existing client agreements. Demand for our services is cyclical and may be vulnerable to sudden economic downturns and reductions in government and private industry spending, which may result in clients delaying, curtailing or canceling proposed and existing projects. Moreover, as a professional services company, maintaining the high quality of the work generated by our employees is integral to our revenue generation and profitability.

        Our costs consist primarily of the compensation we pay to our employees, including salaries, fringe benefits, the costs of hiring subcontractors and other project-related expenses, and sales, general and administrative costs.

        During the year ended September 30, 2011, we adopted a revised definition of revenue provided by acquired companies. We define revenue provided by acquired companies as revenue included in the current period up to twelve months subsequent to their acquisition date.

Acquisitions

        The aggregate value of all consideration for our acquisitions consummated during the year ended September 30, 2012, was $15.4 million for an environmental engineering firm in Asia.

        The aggregate value of all consideration for our acquisitions consummated during the year ended September 30, 2011, was $453.3 million.

        The aggregate value of all consideration for our acquisitions consummated during the year ended September 30, 2010, was $768.0 million.

        All of our acquisitions have been accounted for as business combinations and the results of operations of the acquired companies have been included in our consolidated results since the dates of the acquisitions.

Components of Income and Expense

        Our management analyzes the results of our operations using several financial measures not in accordance with generally accepted accounting principles (GAAP). A significant portion of our revenue relates to services provided by subcontractors and other non-employees that we categorize as other direct costs. Those costs are typically paid to service providers upon our receipt of payment from the client. We segregate other direct costs from revenue resulting in a measurement that we refer to as "revenue, net of other direct costs," which is a measure of work performed by AECOM employees. A large portion of our fees are derived through work performed by AECOM employees rather than other parties. We have included information on revenue, net of other direct costs, as we believe that it is useful to view our revenue exclusive of costs associated with external service providers, and the related gross margins, as discussed in "Results of Operations" below. Because of the importance of maintaining the high quality of work generated by our employees, gross margin is an important metric that we review in evaluating our operating performance.

        The following table presents, for the periods indicated, a presentation of the non-GAAP financial measures reconciled to the closest GAAP measure:

Non-GAAP measure

Revenue

        We generate revenue primarily by providing professional technical and management support services for commercial and government clients around the world. Our revenue consists of both services provided by our employees and pass-through fees from subcontractors and other direct costs. We generally utilize a cost-to-cost approach in applying the percentage-of-completion method of revenue recognition. Under this approach, revenue is earned in proportion to total costs incurred, divided by total costs expected to be incurred.

Other Direct Costs

        In the course of providing our services, we routinely subcontract for services and incur other direct costs on behalf of our clients. These costs are passed through to our clients and, in accordance with industry practice and GAAP, are included in our revenue and cost of revenue. Since subcontractor services and other direct costs can change significantly from project to project and period to period, changes in revenue may not accurately reflect business trends.

Revenue, Net of Other Direct Costs

        Our discussion and analysis of our financial condition and results of operations uses revenue, net of other direct costs as a point of reference. Revenue, net of other direct costs is a non-GAAP measure and may not be comparable to similarly titled items reported by other companies.

Cost of Revenue, Net of Other Direct Costs

        Cost of revenue, net of other direct costs reflects the cost of our own personnel (including fringe benefits and overhead expense) associated with revenue, net of other direct costs.

Amortization Expense of Acquired Intangible Assets

        Included in our cost of revenue, net of other direct costs is amortization of acquired intangible assets. We have ascribed value to identifiable intangible assets other than goodwill in our purchase price allocations for companies we have acquired. These assets include, but are not limited, to backlog and customer relationships. To the extent we ascribe value to identifiable intangible assets that have finite lives, we amortize those values over the estimated useful lives of the assets. Such amortization expense, although non-cash in the period expensed, directly impacts our results of operations.

        It is difficult to predict with any precision the amount of expense we may record relating to acquired intangible assets. As backlog is typically the shortest lived intangible asset in our business, we would expect to see higher amortization expense in the first 12 to 18 months (the typical backlog amortization period) after an acquisition has been consummated.

Equity in Earnings of Joint Ventures

        Equity in earnings of joint ventures includes our portion of fees charged by our unconsolidated joint ventures to clients for services performed by us and other joint venture partners along with earnings we receive from investments in unconsolidated joint ventures.

General and Administrative Expenses

        General and administrative expenses include corporate overhead expenses, including personnel, occupancy, and administrative expenses.

Goodwill Impairment

        See Critical Accounting Policies and Consolidated Results below.

Income Tax Expense

        Income tax expense varies as a function of income before income tax expense and permanent non-tax deductible expenses. As a global enterprise, our tax rates are affected by many factors, including our worldwide mix of earnings, the extent to which those earnings are indefinitely reinvested outside of the United States, our acquisition strategy and changes to existing tax legislation. Our tax returns are routinely audited and settlements of issues raised in these audits sometimes affect our tax provisions.

Critical Accounting Policies

        Our financial statements are presented in accordance with GAAP. Highlighted below are the accounting policies that management considers significant to understanding the operations of our business.

Revenue Recognition

        We generally utilize a cost-to-cost approach in applying the percentage-of-completion method of revenue recognition, under which revenue is earned in proportion to total costs incurred, divided by total costs expected to be incurred. Recognition of revenue and profit under this method is dependent upon a number of factors, including the accuracy of a variety of estimates, including engineering progress, material quantities, the achievement of milestones, penalty provisions, labor productivity and cost estimates. Due to uncertainties inherent in the estimation process, it is possible that actual completion costs may vary from estimates. If estimated total costs on contracts indicate a loss, we recognize that estimated loss in the period the estimated loss first becomes known.

32

Claims Recognition

        Claims are amounts in excess of the agreed contract price (or amounts not included in the original contract price) that we seek to collect from customers or others for delays, errors in specifications and designs, contract terminations, change orders in dispute or unapproved contracts as to both scope and price or other causes of unanticipated additional costs. We record contract revenue related to claims only if it is probable that the claim will result in additional contract revenue and if the amount can be reliably estimated. In such cases, we record revenue only to the extent that contract costs relating to the claim have been incurred. The amounts recorded, if material, are disclosed in the notes to the financial statements. Costs attributable to claims are treated as costs of contract performance as incurred.

Government Contract Matters

        Our federal government and certain state and local agency contracts are subject to, among other regulations, regulations issued under the Federal Acquisition Regulations (FAR). These regulations can limit the recovery of certain specified indirect costs on contracts and subject us to ongoing multiple audits by government agencies such as the Defense Contract Audit Agency (DCAA). In addition, most of our federal and state and local contracts are subject to termination at the discretion of the client.

        Audits by the DCAA and other agencies consist of reviews of our overhead rates, operating systems and cost proposals to ensure that we account for such costs in accordance with the Cost Accounting Standards of the FAR (CAS). If the DCAA determines we have not accounted for such costs consistent with CAS, the DCAA may disallow these costs. There can be no assurance that audits by the DCAA or other governmental agencies will not result in material cost disallowances in the future.

Allowance for Doubtful Accounts

        We record accounts receivable net of an allowance for doubtful accounts. This allowance for doubtful accounts is estimated based on management's evaluation of the contracts involved and the financial condition of its clients. The factors we consider in our contract evaluations include, but are not limited to:

•

Client type—federal or state and local government or commercial client;

•

Historical contract performance;

•

Historical collection and delinquency trends;

•

Client credit worthiness; and

•

General economic conditions.

Unbilled Accounts Receivable and Billings in Excess of Costs on Uncompleted Contracts

        Unbilled accounts receivable represents the contract revenue recognized but not yet billed pursuant to contract terms or accounts billed after the period end.

        Billings in excess of costs on uncompleted contracts represent the billings to date, as allowed under the terms of a contract, but not yet recognized as contract revenue using the percentage-of-completion accounting method.

Investments in Unconsolidated Joint Ventures

        We have noncontrolling interests in joint ventures accounted for under the equity method. Fees received for and the associated costs of services performed by us and billed to joint ventures with respect to work done by us for third-party customers are recorded as our revenues and costs in the period in which such services are rendered. In certain joint ventures, a fee is added to the respective billings from both ourselves and the other joint venture partners on the amounts billed to the third-party customers. These fees result in earnings to the joint venture and are split with each of the joint venture partners and paid to

33

the joint venture partners upon collection from the third-party customer. We record our allocated share of these fees as equity in earnings of joint ventures.

Income Taxes

        Valuation Allowance.    Deferred income taxes are provided on the liability method whereby deferred tax assets and liabilities are established for the difference between the financial reporting and income tax basis of assets and liabilities, as well as operating loss and tax credit carry forwards. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment of such changes to laws and rates.

        Deferred tax assets are reduced by a valuation allowance when, in our opinion, it is more likely than not that some portion or all of the deferred tax assets may not be realized. Whether a deferred tax asset may be realized requires considerable judgment by us. In considering the need for a valuation allowance, we consider a number of factors including the future reversal of existing temporary differences, future taxable income exclusive of reversing temporary differences and carry forwards, taxable income in carry-back years if carry-back is permitted under tax law, and prudent and feasible tax planning strategies that would normally be taken by management, in the absence of the desire to realize the deferred tax asset. Whether a deferred tax asset will ultimately be realized is also dependent on varying factors, including, but not limited to, changes in tax laws and audits by tax jurisdictions in which we operate.

        We review the need for a valuation allowance at least quarterly. If we determine we will not realize all or part of our deferred tax asset in the future, we will record an additional valuation allowance. Conversely, if a valuation allowance exists and we determine that the ultimate realizability of all or part of the net deferred tax asset is more likely than not to be realized, then the amount of the valuation allowance will be reduced. This adjustment will increase or decrease income tax expense in the period of such determination.

        Undistributed Non-U.S. Earnings.    The results of our operations outside of the United States are consolidated for financial reporting; however, earnings from investments in non-U.S. operations are included in domestic U.S. taxable income only when actually or constructively received. No deferred taxes have been provided on the undistributed pre-tax earnings of non-U.S. operations of approximately $797.4 million because we plan to permanently reinvest these earnings overseas. If we were to repatriate these earnings, additional taxes would be due at that time.

Goodwill and Acquired Intangible Assets

        Goodwill represents the excess amounts paid over the fair value of net assets acquired from an acquisition. In order to determine the amount of goodwill resulting from an acquisition, we perform an assessment to determine the value of the acquired company's tangible and identifiable intangible assets and liabilities. In our assessment, we determine whether identifiable intangible assets exist, which typically include backlog and customer relationships.

        We test goodwill for impairment at least annually for each reporting unit. We have multiple reporting units. A reporting unit is defined as an operating segment or one level below an operating segment. Our impairment tests are performed at the operating segment level as they represent our reporting units.

        The impairment test is a two-step process. During the first step, we estimate the fair value of the reporting unit using income and market approaches, and compare that amount to the carrying value of that reporting unit. In the event the fair value of the reporting unit is determined to be less than the carrying value, a second step is required. The second step requires us to perform a hypothetical purchase allocation for that reporting unit and to compare the resulting current implied fair value of the goodwill to the current carrying value of the goodwill for that reporting unit. In the event that the current implied fair value of the goodwill is less than the carrying value, an impairment charge is recognized.

        During the fourth quarter of our year ended September 30, 2012, we conducted our annual goodwill impairment test. The impairment evaluation process includes, among other things, making assumptions

34

about variables such as revenue growth rates, profitability, discount rates, and industry market multiples, which are subject to a high degree of judgment. As a result of the first step of the impairment analysis, due to market conditions and business trends within the Europe, Middle East, and Africa (EMEA) and MSS reporting units, we determined that goodwill was impaired. The second step of the analysis is performed to measure the impairment as the excess of the goodwill carrying value over its implied fair value. This analysis resulted in an impairment of $336.0 million, or $317.2 million, net of tax.

        Material assumptions used in the impairment analysis included the weighted average cost of capital (WACC) percent and terminal growth rates. For example, a 1% increase in the WACC rate represents a $450 million increase to the fair value of our reporting units. A 1% decrease in the terminal growth rate represents a $300 million decrease to the fair value of our reporting units.

Pension Plans

        A number of assumptions are necessary to determine our pension liabilities and net periodic costs. These liabilities and net periodic costs are sensitive to changes in those assumptions. The assumptions include discount rates, long-term rates of return on plan assets and inflation levels limited to the United Kingdom and are generally determined based on the current economic environment in each host country at the end of each respective annual reporting period. We evaluate the funded status of each of our retirement plans using these current assumptions and determine the appropriate funding level considering applicable regulatory requirements, tax deductibility, reporting considerations and other factors. Based upon current assumptions, we expect to contribute $17.3 million to our international plans in fiscal 2013. We do not have a required minimum contribution for our U.S. plans; however, we may make additional discretionary contributions. We currently expect to contribute $8.9 million to our U.S. plans in fiscal 2013. If the discount rate was reduced by 25 basis points, plan liabilities would increase by approximately $31.6 million. If the discount rate and return on plan assets were reduced by 25 basis points, plan expense would increase by approximately $0.3 million and $1.4 million, respectively. If inflation increased by 25 basis points, plan liabilities in the United Kingdom would increase by approximately $16.1 million and plan expense would increase by approximately $1.0 million.

        At each measurement date, all assumptions are reviewed and adjusted as appropriate. With respect to establishing the return on assets assumption, we consider the long term capital market expectations for each asset class held as an investment by the various pension plans. In addition to expected returns for each asset class, we take into account standard deviation of returns and correlation between asset classes. This is necessary in order to generate a distribution of possible returns which reflects diversification of assets. Based on this information, a distribution of possible returns is generated based on the plan's target asset allocation.

        Capital market expectations for determining the long term rate of return on assets are based on forward-looking assumptions which reflect a 20-year view of the capital markets. In establishing those capital market assumptions and expectations, we rely on the assistance of our actuary and our investment consultant. We and the plan trustees review whether changes to the various plans' target asset allocations are appropriate. A change in the plans' target asset allocations would likely result in a change in the expected return on asset assumptions. In assessing a plan's asset allocation strategy, we and the plan trustees consider factors such as the structure of the plan's liabilities, the plan's funded status, and the impact of the asset allocation to the volatility of the plan's funded status, so that the overall risk level resulting from our defined benefit plans is appropriate within our risk management strategy.

        Between September 30, 2011 and September 30, 2012, the aggregate worldwide pension deficit grew from $166.5 million to an estimated $192.2 million. This increase in unfunded liabilities is primarily driven by decreases in U.S. and international discount rates. Although funding rules are subject to local laws and regulations and vary by location, we expect to reduce this deficit over a period of 7 to 10 years. If the various plans do not experience future investment gains to reduce this shortfall, the deficit will be reduced by additional contributions.

35

Accrued Professional Liability Costs

        We carry professional liability insurance policies or self-insure for our initial layer of professional liability claims under our professional liability insurance policies and for a deductible for each claim even after exceeding the self-insured retention. We accrue for our portion of the estimated ultimate liability for the estimated potential incurred losses. We establish our estimate of loss for each potential claim in consultation with legal counsel handling the specific matters and based on historic trends taking into account recent events. We also use an outside actuarial firm to assist us in estimating our future claims exposure. It is possible that our estimate of loss may be revised based on the actual or revised estimate of liability of the claims.

Foreign Currency Translation

        Our functional currency is the U.S. dollar. Results of operations for foreign entities are translated to U.S. dollars using the average exchange rates during the period. Assets and liabilities for foreign entities are translated using the exchange rates in effect as of the date of the balance sheet. Resulting translation adjustments are recorded as a foreign currency translation adjustment into other accumulated comprehensive income/(loss) in stockholders' equity.

        We limit exposure to foreign currency fluctuations in most of our contracts through provisions that require client payments in currencies corresponding to the currency in which costs are incurred. As a result of this natural hedge, we generally do not need to hedge foreign currency cash flows for contract work performed. However, we will use foreign exchange derivative financial instruments from time to time to mitigate foreign currency risk. The functional currency of all significant foreign operations is the respective local currency.

Revenue

        Our revenue for the year ended September 30, 2012, increased $180.8 million, or 2.2%, to $8,218.2 million as compared to $8,037.4 million for the corresponding period last year. Revenue provided by acquired companies was $35.1 million for the year ended September 30, 2012. Excluding the revenue provided by acquired companies, revenue increased $145.7 million, or 1.8%, from the year ended September 30, 2011.

        The increase in revenue, excluding acquired companies, for the year ended September 30, 2012, was primarily attributable to increased demand for our construction management services in the Americas of approximately $220 million, engineering and program management services on infrastructure projects in Australia and Asia of approximately $170 million and $95 million, respectively, partially offset by the effect of foreign currencies of $40 million, a reduction in services in our MSS segment noted below of approximately $220 million, a reduction in engineering and program management services provided in the United States of approximately $50 million, and a reduction in services provided in Libya of approximately $30 million.

Revenue, Net of Other Direct Costs

        Our revenue, net of other direct costs, for the year ended September 30, 2012 increased $3.1 million, or 0.1%, to $5,183.9 million as compared to $5,180.8 million for the corresponding period last year. Revenue, net of other direct costs, of $27.4 million was provided by acquired companies. Excluding revenue, net of other direct costs, provided by acquired companies, revenue, net of other direct costs, decreased $24.3 million, or 0.5%, over the year ended September 30, 2011.

        The decrease in revenue, net of other direct costs, excluding revenue, net of other direct costs provided by acquired companies, for the year ended September 30, 2012, was primarily due to a reduction in engineering and program management services in the United States, the Middle East and Europe of

37

approximately $75 million, $40 million, and $30 million, respectively, in addition to the effect of foreign currencies of $30 million. These decreases were partially offset by an increased demand for our engineering and program management services on infrastructure projects in Australia and Asia of approximately $90 million and $75 million, respectively.

Gross Profit

        Our gross profit for the year ended September 30, 2012 decreased $44.8 million, or 9.6%, to $421.9 million as compared to $466.7 million for the corresponding period last year. Gross profit provided by acquired companies was $3.8 million. Excluding gross profit provided by acquired companies, gross profit decreased $48.6 million, or 10.4%, from the year ended September 30, 2011. For the year ended September 30, 2012, gross profit, as a percentage of revenue, net of other direct costs, decreased to 8.1% from 9.0% in the year ended September 30, 2011.

        The decreases in gross profit and gross profit, as a percentage of revenue, net of other direct costs for the year ended September 30, 2012, as compared to the corresponding period in the prior year were primarily attributable to reductions in gross profit in our MSS segment noted below.

Equity in Earnings of Joint Ventures

        Our equity in earnings of joint ventures for the year ended September 30, 2012, was $48.6 million compared to $44.8 million in the corresponding period last year. No equity in earnings of joint ventures was provided by acquired companies.

        The increase for the year ended September 30, 2012, was primarily due to increased activity in joint ventures on projects for the U.S. Army and Department of Energy, partially offset by decreased activity in a joint venture in Iraq for the U.S. Department of Defense.

General and Administrative Expenses

        Our general and administrative expenses for the year ended September 30, 2012, decreased $9.4 million, or 10.4%, to $80.9 million as compared to $90.3 million for the corresponding period last year. As a percentage of revenue, net of other direct costs, general and administrative expenses decreased from 1.8% in the year ended September 30, 2011, to 1.5% in the year ended September 30, 2012.

        The decrease in general and administrative expenses was primarily attributable to reduced expenses related to employee compensation.

Goodwill Impairment

        During the fourth quarter of our year ended September 30, 2012, we conducted our annual goodwill impairment test. The impairment evaluation process includes, among other things, making assumptions about variables such as revenue growth rates, profitability, discount rates, and industry market multiples, which are subject to a high degree of judgment. As a result of the first step of the impairment analysis, due to market conditions and business trends within the EMEA and MSS reporting units, we determined that goodwill was impaired. The second step of the analysis is performed to measure the impairment as the excess of the goodwill carrying value over its implied fair value. This analysis resulted in an impairment of $336.0 million, or $317.2 million, net of tax.

Other Income

        Our other income for the year ended September 30, 2012, was $9.0 million as compared to $3.4 million for the year ended September 30, 2011.

        Other income is primarily related to investment earnings.

38

Interest Income / Expense—Net

        Our net interest expense for the year ended September 30, 2012, was $45.1 million as compared to $40.4 million of net interest expense for the year ended September 30, 2011.

Income Tax Expense

        Our income tax expense for the year ended September 30, 2012, decreased $25.7 million, or 25.7%, to $74.4 million as compared to $100.1 million for the year ended September 30, 2011. The effective tax rate was 425.7% and 26.1% for the years ended September 30, 2012 and 2011, respectively.

        The 425.7% effective tax rate for the year ended September 30, 2012, differs from the statutory rate of 35% primarily due to the goodwill impairment charge taken during the year, the majority of which is not deductible for tax purposes.

Net (Loss) Income Attributable to AECOM

        The factors described above resulted in the net loss attributable to AECOM of $58.6 million for year ended September 30, 2012, as compared to net income attributable to AECOM of $275.8 million for the year ended September 30, 2011.

Revenue

        Revenue for our PTS segment for the year ended September 30, 2012, increased $399.8 million, or 5.8%, to $7,276.9 million as compared to $6,877.1 million for the corresponding period last year. Revenue provided by acquired companies was $35.1 million. Excluding revenue provided by acquired companies, revenue increased $364.7 million, or 5.3%, over the year ended September 30, 2011.

        The increase in revenue, excluding acquired companies, for the year ended September 30, 2012, was primarily attributable to increased demand for our construction management services in the Americas of

39

approximately $220 million, engineering and program management services on infrastructure projects in Australia and Asia of approximately $170 million and $95 million, respectively, partially offset by the effect of foreign currencies of $40 million, a reduction in engineering and program management services provided in the United States of approximately $50 million, and a reduction in services provided in Libya of approximately $30 million.

Revenue, Net of Other Direct Costs

        Revenue, net of other direct costs, for our PTS segment for the year ended September 30, 2012, decreased $4.9 million, or 0.1%, to $4,607.3 million as compared to $4,612.2 million for the corresponding period last year. Revenue, net of other direct costs provided by acquired companies was $27.4 million. Excluding revenue, net of other direct costs, provided by acquired companies, revenue, net of other direct costs, decreased $32.3 million, or 0.7%, over the year ended September 30, 2011.

        The decrease in revenue, net of other direct costs, excluding revenue, net of other direct costs provided by acquired companies, for the year ended September 30, 2012, was primarily due to decreased engineering and program management services in the United States, the Middle East and Europe of $75 million, $40 million, and $30 million, respectively, in addition to the effect of foreign currencies of $30 million. These decreases were partially offset by increased demand for our engineering and program management services on infrastructure projects in Australia and Asia of approximately $90 million and $75 million, respectively. Revenue, net of other direct costs, excluding the effects of acquired companies, was relatively consistent with the prior period primarily due to the increase in subcontractor costs from our construction management services.

Gross Profit

        Gross profit for our PTS segment for the year ended September 30, 2012, increased $6.1 million, or 1.5%, to $423.8 million as compared to $417.7 million for the corresponding period last year. Gross profit provided by acquired companies was $3.8 million. Excluding gross profit provided by acquired companies, gross profit increased $2.3 million, or 0.6%, from the year ended September 30, 2011. As a percentage of revenue, net of other direct costs, gross profit increased to 9.2% of revenue, net of other direct costs, for the year ended September 30, 2012, from 9.1% in the corresponding period last year.

        Revenue, net of other direct costs, for our MSS segment for the year ended September 30, 2012, increased $8.0 million, or 1.4%, to $576.6 million as compared to $568.6 million for the corresponding period last year. No revenue, net of other direct costs, was provided by acquired companies.

        Gross (loss) profit for our MSS segment for the year ended September 30, 2012, decreased $50.9 million, or 103.9%, to $(1.9) million as compared to $49.0 million for the corresponding period last year. As a percentage of revenue, net of other direct costs, gross (loss) profit decreased to (0.3)% of revenue, net of other direct costs, for the year ended September 30, 2012, from 8.6% in the corresponding period last year. No gross profit was provided by acquired companies.

        The decrease in gross (loss) profit and gross (loss) profit, as a percentage of revenue, net of other direct costs, for the year ended September 30, 2012, was primarily due to reduced revenue from the combat support project noted in Revenue above, and decreased performance on several projects in our national security programs and contract field teams services, and the settlement of the previously disclosed Combat Support Associates Defense Contract Audit Agency Form 1.

Revenue

        Our revenue for the year ended September 30, 2011, increased $1.5 billion, or 22.8%, to $8.0 billion as compared to $6.5 billion for the prior year. Excluding revenue provided by acquired companies, revenue decreased $119.9 million, or 1.8%, from the year ended September 30, 2010.

        The decrease in revenue, excluding acquired companies, for the year ended September 30, 2011, was primarily attributable to reductions in services for clients in Libya, United States, Europe, and Canada of approximately $90 million, $40 million, $40 million, and $30 million, respectively, and a $297 million decrease in our MSS segment primarily due to the completion of the project with the U.S. government noted below in the segment information. These decreases were partially offset by increased demand for our engineering program management services on infrastructure projects in Australia and Asia of approximately $150 million and $65 million, respectively, and approximately $155 million in increased revenue attributable to stronger foreign currencies (primarily the Australian and Canadian dollars).

Revenue, Net of Other Direct Costs

        Our revenue, net of other direct costs for the year ended September 30, 2011, increased $975.0 million, or 23.2%, to $5.2 billion as compared to $4.2 billion for the prior year. Excluding revenue, net of other direct costs provided by acquired companies, revenue, net of other direct costs increased $201.2 million, or 4.8%, over the year ended September 30, 2010.

        The increase in revenue, net of other direct costs, excluding acquired companies, for the year ended September 30, 2011, was primarily attributable to increased demand for our engineering and program management services on infrastructure projects in Australia, and Asia of approximately $115 million, and $55 million, respectively, and approximately $125 million in increased revenue, net of other direct costs, attributable to stronger foreign currencies (primarily the Australian and Canadian dollars). Additionally,

43

we experienced an increase of $51 million in our MSS segment. These increases were partially offset by reductions in services for clients in Libya, the United States, and Europe of $55 million, $50 million, and $35 million, respectively.

Gross Profit

        Our gross profit for the year ended September 30, 2011, increased $36.4 million, or 8.5%, to $466.7 million, as compared to $430.3 million in the prior year. Excluding gross profit provided by acquired companies, gross profit decreased $11.6 million, or 2.7%, from the year ended September 30, 2010. For the year ended September 30, 2011, gross profit, as a percentage of revenue, net of other direct costs, decreased to 9.0% from 10.2% in the year ended September 30, 2010.

        The increase in gross profit for the year ended September 30, 2011, was primarily due to increases in revenue, net of other direct costs, pension curtailment gains in our PTS segment of $4.2 million, and gross profit provided by our MSS segment, partially offset by the cessation of service provided under the Libyan Housing and Infrastructure Board project. Additionally, challenges in our Western European business, particularly in the United Kingdom, led us to restructure certain portions of this business in order to reduce our cost structure. The result of such actions resulted in facility exit and employee severance expenses of $12 million during the three months ended September 30, 2011.

Equity in Earnings of Joint Ventures

        Our equity in earnings of joint ventures for the year ended September 30, 2011, increased $23.8 million, or 113%, to $44.8 million as compared to $21.0 million in the prior year. Excluding acquired companies, equity in earnings of joint ventures increased $9.5 million.

        The increase, excluding acquired companies, was primarily due to increased activity in a joint venture that provides service to the U.S. Navy.

General and Administrative Expenses

        Our general and administrative expenses for the year ended September 30, 2011, decreased $20.2 million, or 18.3%, to $90.3 million as compared to $110.5 million for the prior year. For the year ended September 30, 2011, general and administrative expenses, as a percentage of revenue, net of other direct costs was 1.8% as compared to 2.6% in the prior year.

        The decrease in general and administrative expenses was primarily attributable to reduced expenses related to employee compensation and acquisitions.

Other Income / Expense

        Our other income for the year ended September 30, 2011, was $3.4 million as compared to other income of $10.2 million for the year ended September 30, 2010.

        Other income is primarily comprised of net gains and losses on investments we hold related to a deferred compensation plan, which was terminated in December 2010, as discussed in Note 17 in the notes to our consolidated financial statements. The decrease was primarily due to this termination.

Interest Income / Expense—Net

        Our net interest expense for the year ended September 30, 2011, was $40.4 million as compared to $9.9 million for the year ended September 30, 2010.

        The increase in interest expense primarily relates to increased borrowings associated with the funding of acquisitions.

44

Income Tax Expense

        Our income tax expense for the year ended September 30, 2011, increased $8.4 million to $100.1 million as compared to $91.7 million for the year ended September 30, 2010. The effective tax rate was 26.1% and 26.9% for the years ended September 30, 2011, and 2010, respectively.

        During the fiscal year ended September 30, 2011, our effective tax rate was favorably impacted by lower tax rates applied to foreign earnings and a one-time benefit from the retroactive extension of the U.S. federal research credit during the year. During the fiscal year ended September 30, 2010, our effective tax rate was decreased due to a remeasurement of existing uncertain tax positions for effectively settled audit issues related to fiscal years ended September 30, 2007, and September 30, 2006.

Net Income Attributable to AECOM

        The factors described above resulted in net income attributable to AECOM of $275.8 million for the year ended September 30, 2011, as compared to $236.9 million for the year ended September 30, 2010.

Revenue

        Revenue for our PTS segment for the year ended September 30, 2011, increased $1.5 billion, or 27.5%, to $6.9 billion as compared to $5.4 billion for the prior year. Excluding revenue provided by acquired companies, revenue increased $177.4 million, or 3.3%, over the year ended September 30, 2010.

        The increase in revenue, excluding acquired companies, for the year ended September 30, 2011, was primarily attributable to increased demand for our engineering and program management services on infrastructure projects in Australia, and Asia of approximately $150 million, and $65 million, respectively, and approximately $155 million in increased revenue attributable to stronger foreign currencies (primarily the Australian and Canadian dollars). These increases were partially offset by reductions in services for

Excluding revenue, net of other direct costs provided by acquired companies, revenue, net of other direct costs, increased $150.7 million, or 3.9%, over the year ended September 30, 2010.

        The increase in revenue, net of other direct costs, excluding acquired companies, for the year ended September 30, 2011, was primarily attributable to increased demand for our engineering and program management services on infrastructure projects in Australia and Asia of approximately $115 million and $55 million, respectively, and approximately $125 million in increased revenue, net of other direct costs, attributable to stronger foreign currencies (primarily the Australian and Canadian dollars). These increases were partially offset by reductions in services in Libya, the United States and Europe of $55 million, $50 million and $35 million, respectively.

Gross Profit

        Gross profit for our PTS segment for the year ended September 30, 2011, increased $27.9 million, or 7.2%, to $417.7 million as compared to $389.8 million for the prior year. Excluding gross profit provided by acquired companies, gross profit decreased $5.3 million, or 1.4%. As a percentage of revenue, net of other direct costs, gross profit decreased to 9.1% of revenue, net of other direct costs, for the year ended September 30, 2011, from 10.2% in the prior year.

        The increase in gross profit for the year ended September 30, 2011, was primarily attributable to the increase in revenue, net of other direct costs, pension curtailment gains of $4.2 million, and stronger foreign currencies (primarily the Australian and Canadian dollars) of $10 million, partially offset by a $24.5 million reduction resulting from the Libyan project. Additionally, challenges in our Western European business, particularly in the United Kingdom, led us to restructure certain portions of this business in order to reduce our cost structure, including facility exit and employee severance costs. The result of such actions resulted in expenses of $12 million during the fourth quarter ended September 30, 2011.

Revenue

        Revenue for our MSS segment for the year ended September 30, 2011, increased $8.2 million, or 0.7%, to $1.2 billion as compared to $1.2 billion for the prior year. Excluding revenue provided by acquired companies, revenue decreased $297.3 million, or 25.8%, over the year ended September 30, 2010.

        The decrease in revenue, excluding revenue provided by acquired companies, for the year ended September 30, 2011, was primarily attributable to $355 million in decreased activity from our Combat Support project with the U.S. government in the Middle East, which was completed in February 2011.

Revenue, Net of Other Direct Costs

        Revenue, net of other direct costs for our MSS segment for the year ended September 30, 2011, increased $202.1 million, or 55.1%, to $568.6 million as compared to $366.5 million for the prior year. Excluding revenue, net of other direct costs provided by acquired companies, revenue, net of other direct costs, increased $50.5 million, or 13.8%, over the year ended September 30, 2010.

        The increase in revenue, net of other direct costs, excluding acquired companies, for the year ended September 30, 2011, was primarily attributable to increased activity of self-performed work for our global maintenance and support services for the United States Army and various projects with United States security and intelligence agencies.

Gross Profit

        Gross profit for our MSS segment for the year ended September 30, 2011, increased $8.5 million, or 21.0%, to $49.0 million as compared to $40.5 million for the prior year. Excluding gross profit provided by acquired companies, gross profit decreased $6.3 million, or 15.6%. As a percentage of revenue, net of other direct costs, gross profit decreased to 8.6% in the year ended September 30, 2011, from 11.1% in the prior year.

        The decrease in gross profit, excluding acquired companies, for the year ended September 30, 2011, was primarily attributable to decreased activity from our Combat Support project with the U.S. government in the Middle East, which was completed in February 2011.

        The decrease in gross profit, as a percentage of revenue, net of other direct costs for the year ended September 30, 2011, was primarily due to decreased activity from our Combat Support project and a depot maintenance project for the United States Army.

Seasonality

        We experience seasonal trends in our business. Our revenue is typically higher in the last half of the fiscal year. The fourth quarter of our fiscal year (July 1 to September 30) is typically our strongest quarter. We find that the U.S. Federal Government tends to authorize more work during the period preceding the end of our fiscal year, September 30. In addition, many U.S. state governments with fiscal years ending on

47

June 30 tend to accelerate spending during their first quarter, when new funding becomes available. Further, our construction management revenue typically increases during the high construction season of the summer months. Within the United States, as well as other parts of the world, our business generally benefits from milder weather conditions in our fiscal fourth quarter, which allows for more productivity from our on-site civil services. Our construction and project management services also typically expand during the high construction season of the summer months. The first quarter of our fiscal year (October 1 to December 31) is typically our weakest quarter. The harsher weather conditions impact our ability to complete work in parts of North America and the holiday season schedule affects our productivity during this period. For these reasons, coupled with the number and significance of client contracts commenced and completed during a particular period, as well as the timing of expenses incurred for corporate initiatives, it is not unusual for us to experience seasonal changes or fluctuations in our quarterly operating results.

Liquidity and Capital Resources

Cash Flows

        Our principal sources of liquidity are cash flows from operations, borrowings under our credit facilities, and access to financial markets. Our principal uses of cash are operating expenses, capital expenditures, working capital requirements, acquisitions, repurchases of stock under our stock repurchase program and repayment of debt. We believe our anticipated sources of liquidity including operating cash flows, existing cash and cash equivalents, borrowing capacity under our revolving credit facility and our ability to issue debt or equity, if required, will be sufficient to meet our projected cash requirements for at least the next 12 months. In the quarter ended September 30, 2011, we amended our term credit agreement to increase our bank term loans from $600 million to $750 million maturing July 2016, and also increased our borrowing capacity to $1.05 billion under our revolving credit facility which expires in July 2016.

        At September 30, 2012, cash and cash equivalents were $593.8 million, an increase of $136.9 million, or 30.0%, from $456.9 million at September 30, 2011. The increase in cash and cash equivalents was primarily attributable to net cash provided by operating activities and a decrease in cash payments for business acquisitions partially offset by our net repayment of borrowings.

        Net cash provided by operating activities was $433.4 million for the year ended September 30, 2012, an increase of $301.4 million from $132.0 million for the year ended September 30, 2011. The increase was primarily attributable to the timing of receipts and payments of working capital, which include accounts receivable, accounts payable, accrued expenses, and billings in excess of costs on uncompleted contracts. The increase provided by our accounts receivable was partially due to the sale of trade receivables to a financial institution, of which $31.2 million was outstanding as of September 30, 2012, as discussed in Note 6, Accounts Receivable—Net, in the notes to our consolidated financial statements. We expect to continue to sell trade receivables in the future as long as the terms continue to remain favorable to AECOM. The change was also due to payments made in December 2010 for the $89.7 million settlement of our U.S. deferred compensation plan liability and a decrease of $60.0 million in excess tax benefit from share-based payments, which was primarily attributable to this plan's equity distribution.

        Net cash used in investing activities was $73.8 million for the year ended September 30, 2012, compared with $421.9 million for the year ended September 30, 2011. This decrease was primarily attributable to a $353.0 million decrease in payments for business acquisitions, partially offset by a $63.3 million decrease in proceeds from the sale of investments in a rabbi trust due to the settlement of our U.S. deferred compensation plan liability.

        Net cash used in financing activities was $237.6 million for the year ended September 30, 2012, compared with net cash provided by financing activities of $137.5 million for the year ended September 30, 2011. The change was primarily attributable to a $319.4 million decrease in net borrowings under credit

48

agreements, primarily due to reduced business combinations and a decrease of $60.0 million in excess tax benefit from share-based payments, which was primarily attributable to our U.S. deferred compensation plan distribution in December 2010.

Working Capital

        Working capital, or current assets less current liabilities, decreased $106.7 million, or 9.1%, to $1,068.9 million at September 30, 2012, from $1,175.6 million at September 30, 2011. Net accounts receivable, which includes billed and unbilled costs and fees, net of billings in excess of costs on uncompleted contracts, increased $20.3 million, or 1.0%, to $2,075.6 million at September 30, 2012.

        Accounts receivable increased 0.7%, or $15.7 million, to $2,395.9 million at September 30, 2012, from $2,380.2 million at September 30, 2011.

        Days Sales Outstanding (DSO), including accounts receivable, net of billings in excess of costs on uncompleted contracts, excluding the effects of recent acquisitions, at September 30, 2012, was 91 days compared to the 88 days at September 30, 2011.

        In Note 6, Accounts Receivable—Net, in the notes to our consolidated financial statements, a comparative analysis of the various components of accounts receivable is provided. Substantially all unbilled receivables are expected to be billed and collected within twelve months.

        Unbilled receivables related to claims are recorded only if it is probable that the claim will result in additional contract revenue and if the amount can be reliably estimated. In such cases, revenue is recorded only to the extent that contract costs relating to the claim have been incurred. Other than as disclosed, there are no significant net receivables related to contract claims as of September 30, 2012 and 2011. Award fees in unbilled receivables are accrued only when there is sufficient information to assess contract performance. On contracts that represent higher than normal risk or technical difficulty, award fees are generally deferred until an award fee letter is received.

        Because our revenue depends to a great extent on billable labor hours, most of our charges are invoiced following the end of the month in which the hours were worked, the majority usually within 15 days. Other direct costs are normally billed along with labor hours. However, as opposed to salary costs, which are generally paid on either a bi-weekly or monthly basis, other direct costs are generally not paid until payment is received (in some cases in the form of advances) from the customers.

Unsecured Term Credit Agreement

        In September 2011, we entered into an Amended and Restated Credit Agreement (the "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, we borrowed $750 million in term loans on the closing date and may borrow up to an additional $100 million in term loans upon our request subject to certain conditions, including Company and lender approval. We used approximately $600 million of the proceeds from the loans to repay indebtedness under our prior term loan facility, approximately $147 million of the proceeds to pay down indebtedness under our revolving credit facility and a portion of the proceeds to pay fees and expenses related to the Term Credit Agreement. The loans under the Term Credit Agreement bear interest, at our 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 0.375% to 1.50% and the applicable margin for Eurodollar Rate loans is a range of 1.375% to 2.50%, both based on our debt-to-earnings leverage ratio at the end of each fiscal quarter. The initial interest rate of the loans borrowed on September 30, 2011, was the 3 month Eurodollar rate plus 1.75%, or a total of 2.12%. For the years ended September 30, 2012 and 2011, the average interest rate of our term loan facility was 2.19% and 3.01%, respectively. Payments of the initial principal amount outstanding under the Term Credit Agreement are required on a quarterly basis beginning on December 31, 2012, while interest payments are made on a quarterly basis beginning December 31, 2011. Any remaining principal of the loans under the Term Credit Agreement is due no later than July 20, 2016. Accrued interest is payable in arrears on a quarterly basis for Base Rate loans, and at the end of the applicable interest period (but at least every three months) for Eurodollar Rate loans. We may optionally prepay the loans at any time, without penalty.

Unsecured Senior Notes

        In July 2010, we 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 was $81.8 million and $78.6 million at September 30, 2012 and 2011, respectively, which have an effective interest rate of 5.62%. The fair value of our unsecured senior notes was approximately $277.8 million at September 30, 2012, and $259.2 million at September 30, 2011. We calculated the fair values based on model-derived valuations using market observable inputs, which are Level 2 inputs under the accounting guidance. Our obligations under the notes are guaranteed by certain of our subsidiaries pursuant to one or more subsidiary guarantees.

Unsecured Revolving Credit Facility

        In July 2011, we entered into a Third Amended and Restated Credit Agreement (the "Revolving Credit Agreement") with Bank of America, N.A., as an administrative agent and a lender and the other

50

lenders party thereto, which amended and restated our unsecured revolving credit facility and increased our available borrowing capacity to $1.05 billion in order to support our working capital and acquisition needs. The Revolving Credit Agreement has an expiration date of July 20, 2016, and prior to this expiration date, principal amounts outstanding under the Revolving Credit Agreement may be repaid and reborrowed at our option without prepayment or penalty, subject to certain conditions. We may also, at our option, request an increase in the commitments under the facility up to a total of $1.15 billion, subject to certain conditions, including Company and lender approval. The loans under the Revolving Credit Agreement may be borrowed in dollars or in certain foreign currencies and bear interest, at our 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 0.0% to 1.50% and the applicable margin for Eurocurrency Rate loans is a range of 1.00% to 2.50%, both based on our 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 0.150% to 0.375% on any unused commitment. Accrued interest is payable in arrears on a quarterly basis for Base Rate loans, and at the end of the applicable interest period (but at least every three months) for Eurocurrency Loans. At September 30, 2012 and 2011, $24.0 million and $101.4 million, respectively, were outstanding under our revolving credit facility. At September 30, 2012 and 2011, outstanding standby letters of credit totaled $35.1 million and $32.1 million, respectively, under our revolving credit facility. As of September 30, 2012, we had $990.9 million available under our Revolving Credit Agreement.

Covenants and Restrictions

        Under our debt agreements relating to our unsecured revolving credit facility and unsecured term credit agreements, we are subject to a maximum consolidated leverage ratio at the end of any fiscal quarter. This ratio is calculated by dividing consolidated funded debt (including financial letters of credit) by consolidated earnings before interest, taxes, depreciation, and amortization (EBITDA). For our 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 our acquisitions). As of September 30, 2012, our consolidated leverage ratio was 2.15, which did not exceed our most restrictive maximum consolidated leverage ratio of 3.0.

        Our Revolving Credit Agreement and Term Credit Agreement also contain certain covenants that limit our 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, our 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 us 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, we cannot include a consolidated net loss that may occur in any fiscal quarter. Our 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 September 30, 2012, this amount was $2.2 billion, which exceeds the calculated threshold of $1.5 billion.

51

        Should we fail to comply with these covenants, all or a portion of our borrowings under the unsecured senior notes and unsecured term credit agreements could become immediately payable and our unsecured revolving credit facility could be terminated. At September 30, 2012, we were in compliance with all such covenants.

        Our average effective interest rate on borrowings, including the effects of the swaps agreements, refer to Note 11 in the notes to our consolidated financial statements for additional information regarding our interest rate swap agreements, during the years ended September 30, 2012 and 2011 was 3.1% and 3.3%, respectively.

Notes Secured by Real Properties

        Notes secured by real properties, payable to a bank, were assumed in connection with a business acquired during the year ended September 30, 2008. These notes payable bear interest at 6.04% per annum and mature in December 2028.

Other Debt

        Other debt consists primarily of bank overdrafts and obligations under capital leases. In addition to the revolving credit facility discussed above, at September 30, 2012, we had $470.1 million of unsecured credit facilities primarily used to cover periodic overdrafts and standby letters of credit, of which $209.8 million was utilized for outstanding standby letters of credit.

Commitments and Contingencies

        Other than normal property and equipment additions and replacements, expenditures to further the implementation of our Enterprise Resource Planning system, commitments under our incentive compensation programs, amounts we may expend to repurchase stock under our stock repurchase program and acquisitions from time to time, we currently do not have any significant capital expenditures or outlays planned except as described below. However, as we acquire additional businesses in the future or if we embark on other capital-intensive initiatives, additional working capital may be required.

        Under our unsecured revolving credit facility and other facilities discussed in Other Debt above, as of September 30, 2012, there was approximately $244.9 million outstanding under standby letters of credit issued primarily in connection with general and professional liability insurance programs and for contract performance guarantees. For those projects for which we have issued a performance guarantee, if the project subsequently fails to meet guaranteed performance standards, we may either incur significant additional costs or be held responsible for the costs incurred by the client to achieve the required performance standards.

        We recognized on our balance sheet the funded status (measured as the difference between the fair value of plan assets and the projected benefit obligation) of our pension plans. The total amounts of employer contributions paid for the year ended September 30, 2012, were $13.2 million for U.S. plans and $17.2 million for non-U.S. plans. Funding requirements for each plan are determined based on the local laws of the country where such plan resides. In certain countries, the funding requirements are mandatory while in other countries, they are discretionary. We do not have a required minimum contribution for our domestic plans; however, we may make additional discretionary contributions. In the future, such pension funding may increase or decrease depending on changes in the levels of interest rates, pension plan performance and other factors.

Combat Support Associates Joint Venture

        As of September 30, 2012, we have settled the previously disclosed Combat Support Associates Defense Contract Audit Agency (DCAA) Form 1 matter.

52

Global Linguists Solutions Joint Venture

        On October 5, 2011 and February 8, 2012, the DCAA issued DCAA Forms 1 questioning costs incurred by Global Linguists Solutions (GLS), an equity method joint venture, of which McNeil Technologies Inc., which we acquired in August 2010, is an owner. The questioned costs were incurred by GLS during fiscal 2009, a period prior to the acquisition. Specifically, the DCAA questioned direct labor, associated burdens, and fees billed to the U.S. Government for linguists that allegedly did not meet specific contract requirements. As a result of the issuance of the DCAA Forms 1, the U.S. Government has withheld approximately $19 million from payments on current year billings pending final resolution.

        GLS is performing a review of the issues raised in the Forms 1 in order to respond fully to the questioned costs. Based on a review, GLS believes that the costs met the applicable contract requirements.

        Additionally, on April 20, 2012, GLS received a subpoena from the Inspector General of the U.S. Department of Defense requesting documentation related to this contract with the United States Army. GLS plans to respond fully to the request. If the DCAA Forms 1 are not overruled and subsequent appeals are unsuccessful or there are unfavorable consequences from the Inspector General's investigation, these events could have a material adverse effect on our results of operations.

AECOM Australia

        In 2005 and 2006, our 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 a special purpose vehicle (SPV) that raised approximately $700 million Australian dollars through an initial public offering (IPO) of equity units in 2006 and another approximately $1.4 billion Australian dollars in long term bank loans. The SPV (and certain affiliated SPVs) went into insolvency administrations in February 2011.

        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. Separately, KordaMentha, the receivers for the SPVs, filed a lawsuit in the Federal Court of Australia on May 14, 2012, claiming damages that purportedly resulted from AECOM Australia's role in connection with the above described traffic forecast. WestLB, one of the lending banks to the SPVs, filed a lawsuit in the Federal Court of Australia on May 18, 2012. Centerbridge Credit Partners (and a number of related entities) and Midtown Acquisitions (and a number of related entities), both claiming to be assignees of certain other lending banks, previously filed their own proceedings in the Federal Court of Australia and then subsequently withdrew the lawsuits. None of the lawsuits specify the amount of damages sought and the damages sought by WestLB are duplicative of damages already included in the receivers' claim.

        AECOM Australia intends to vigorously defend the claims brought against it.

Hawaii Project

        The U.S. Attorney's Office (USAO) informed us that the USAO and the U.S. Environmental Protection Agency are investigating potential criminal charges in connection with services our subsidiary provided to the operator of the Waimanalo Gulch Sanitary Landfill in Hawaii. We have cooperated fully with the investigation and, as of this date, no actions have been filed. We believe that the investigation will show that there has been no criminal wrongdoing on our part or any of our subsidiaries and, if any actions are brought, we intend to vigorously defend against such actions.

        The services performed by the subsidiary included the preparation of a pollution control plan, which the operator used to obtain permits necessary for the operation of the landfill. The USAO is investigating whether flooding at the landfill that resulted in the discharge of waste materials and storm water into the

53

Pacific Ocean in December 2010 and January 2011 was due in part to reliance on information contained in the plan prepared by our subsidiary.

Contractual Obligations and Commitments

New Accounting Pronouncements and Changes in Accounting

        In January 2010, the Financial Accounting Standards Board (FASB) issued guidance to amend the disclosure requirements related to fair value measurements. We adopted this guidance for the quarter ended March 31, 2010, except for the portion of the guidance that requires the disclosure of activities on purchases, sales, issuance, and settlements of the assets and liabilities measured using significant unobservable inputs (Level 3 fair value measurements). The Level 3 fair value measurement guidance was adopted by us in our fiscal year beginning October 1, 2011. Since the Company carried no material Level 3 assets or liabilities during the period, the adoption of the separate disclosures related to Level 3 measurements did not have a material impact on our consolidated financial statements. Additionally, the FASB issued a new accounting standard on fair value measurements that changes certain fair value measurement principles, clarifies the requirement for measuring fair value and expands disclosure requirements, particularly for Level 3 fair value measurements. This guidance was effective for us in our second quarter ending March 31, 2012, and did not have a material impact on our consolidated financial statements.

        In June 2011, the FASB issued guidance on the presentation of comprehensive income. The new standard will require companies to present items of net income, items of other comprehensive income and total comprehensive income in one continuous statement or two separate consecutive statements, and companies will no longer be allowed to present items of other comprehensive income in the statement of stockholders' equity. This guidance is effective for us in our fiscal year beginning October 1, 2012, and, although it will change the financial statement presentation, it is not expected to have a material impact on our financial condition or results of operations.

        In September 2011, the FASB issued guidance intended to simplify goodwill impairment testing. Entities are allowed to 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 as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. This guidance is effective for goodwill impairment tests performed in interim and annual periods for fiscal years beginning after December 15, 2011, with early adoption permitted. We do not expect this guidance will have a material impact on our consolidated financial statements.

54

Off-Balance Sheet Arrangements

        We enter into various joint venture arrangements to provide architectural, engineering, program management, construction management and operations and maintenance services. The ownership percentage of these joint ventures is typically representative of the work to be performed or the amount of risk assumed by each joint venture partner. Some of these joint ventures are considered variable interest entities. We have consolidated all joint ventures for which we have control. For all others, our portion of the earnings are recorded in equity in earnings of joint ventures. See Note 8 in the notes to our consolidated financial statements. We do not believe that we have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that would be material to investors.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Financial Market Risks

        We are exposed to market risk, primarily related to foreign currency exchange rates and interest rate exposure of our debt obligations that bear interest based on floating rates. We actively monitor these exposures. Our objective is to reduce, where we deem appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign exchange rates and interest rates. In the past, we have entered into derivative financial instruments, such as forward contracts and interest rate hedge contracts. It is our policy and practice to use derivative financial instruments only to the extent necessary to manage our exposures. We do not use derivative financial instruments for trading purposes.

Foreign Exchange Rates

        We are exposed to foreign currency exchange rate risk resulting from our operations outside of the U.S. We do not comprehensively hedge our exposure to currency rate changes; however, our exposure to foreign currency fluctuations is limited in that most of our contracts require client payments to be in currencies corresponding to the currency in which costs are incurred. As a result, we typically do not need to hedge most foreign currency cash flows for contract work performed. The functional currency of our significant foreign operations is the local currency.

Interest Rates

        Our senior revolving credit facility and certain other debt obligations are subject to variable rate interest which could be adversely affected by an increase in interest rates. As of September 30, 2012 and 2011, we had $774.0 million and $851.4 million, respectively, outstanding borrowings under our credit facility and our term credit agreements. Interest on amounts borrowed under the credit facility and our term credit agreements is subject to adjustment based on certain levels of financial performance. These borrowings are at offshore rates, for which the applicable margin added can range from 1% to 2.5%. For the year ended September 30, 2012, our weighted average floating rate borrowings were $413.5 million. If short term floating interest rates had increased or decreased by 1%, our annual interest expense would have increased or decreased by $4.1 million. We invest our cash in a variety of financial instruments, consisting principally of money market securities or other highly liquid, short-term securities that are subject to minimal credit and market risk.

Report of Independent Registered Public Accounting Firm

The Board of Directors and stockholders of
AECOM Technology Corporation

        We have audited the accompanying consolidated balance sheets of AECOM Technology Corporation (the "Company") as of September 30, 2012 and 2011, and the related consolidated statements of operations, stockholders' equity, and cash flows for each of the three years in the period ended September 30, 2012. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of AECOM Technology Corporation at September 30, 2012 and 2011, and the consolidated results of its operations and its cash flows for each of the three years in the period ended September 30, 2012, in conformity with U.S. generally accepted accounting principles.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), AECOM Technology Corporation's internal control over financial reporting as of September 30, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway and our report dated November 16, 2012 expressed an unqualified opinion thereon.

        Our audit was conducted for the purpose of forming an opinion on the financial statements as a whole. The information contained in Schedule II: Valuation and Qualifying Accounts included in Item 8 on page 108 of the Form 10-K is presented for purposes of additional analysis and is not a required part of the financial statements. Such information is the responsibility of management and was derived from and relates directly to the underlying accounting and other records used to prepare the financial statements. The information has been subjected to the auditing procedures applied in the audit of the financial statements and certain additional procedures, including comparing and reconciling such information directly to the underlying accounting and other records used to prepare the financial statements or to the financial statements themselves, and other additional procedures in accordance with auditing standards generally accepted in the United States of America. In our opinion, the information is fairly stated in all material respects in relation to the financial statements as a whole.

Report of Independent Registered Public Accounting Firm

The Board of Directors and stockholders of
AECOM Technology Corporation

        We have audited AECOM Technology Corporation's (the "Company") internal control over financial reporting as of September 30, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the "COSO criteria"). AECOM Technology Corporation's management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company's internal control over financial reporting based on our audit.

        We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        In our opinion, AECOM Technology Corporation maintained, in all material respects, effective internal control over financial reporting as of September 30, 2012, based on the COSO criteria.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of AECOM Technology Corporation as of September 30, 2012 and 2011, and the related consolidated statements of operations, stockholders' equity, and cash flows for each of the three years in the period ended September 30, 2012 and our report dated November 16, 2012 expressed an unqualified opinion thereon.

AECOM TECHNOLOGY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Significant Accounting Policies

        Organization—AECOM Technology Corporation and its consolidated subsidiaries (the Company) provide professional technical and management support services for commercial and government clients around the world. These services encompass a variety of technical disciplines, including consulting, planning, architectural and engineering design, and program and construction management for a broad range of projects. These services are applied to a number of areas and industries, including transportation infrastructure; research, testing and defense facilities; water, wastewater and other environmental programs; land development; security and communication systems; institutional, mining, industrial and commercial and energy-related facilities. The Company also provides operations and maintenance services to governmental agencies throughout the U.S. and abroad.

        Fiscal Year—The Company reports results of operations based on 52 or 53-week periods ending on the Friday nearest September 30. For clarity of presentation, all periods are presented as if the year ended on September 30. Fiscal years 2012, 2011 and 2010 each contained 52 weeks and ended on September 28, September 30, and October 1, respectively.

        Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant estimates affecting amounts reported in the consolidated financial statements relate to revenues under long-term contracts and self-insurance accruals. Actual results could differ from those estimates.

        Principles of Consolidation and Presentation—The consolidated financial statements include the accounts of all majority-owned subsidiaries and material joint ventures in which the Company is the primary beneficiary. All inter-company accounts have been eliminated in consolidation. Also see Note 8 regarding joint ventures.

        Revenue Recognition—The Company generally utilizes a cost-to-cost approach in applying the percentage-of-completion method of revenue recognition. Under this approach, revenue is earned in proportion to total costs incurred, divided by total costs expected to be incurred. Recognition of revenue and profit is dependent upon a number of factors including, the accuracy of a variety of estimates made at the balance sheet date, engineering progress, materials quantities, the achievement of milestones, penalty provisions, labor productivity and cost estimates made at the balance sheet date. Due to uncertainties inherent in the estimation process, actual completion costs may vary from estimates. If estimated total costs on contracts indicate a loss, the Company recognizes that estimated loss in the period the estimated loss first becomes known.

        In the course of providing its services, the Company routinely subcontracts for services and incurs other direct costs on behalf of its clients. These costs are passed through to clients and, in accordance with industry practice and GAAP, are included in the Company's revenue and cost of revenue. Because subcontractor services and other direct costs can change significantly from project to project and period to period, changes in revenue may not be indicative of business trends. These other direct costs for the years ended September 30, 2012, 2011 and 2010 were $3.0 billion, $2.9 billion and $2.3 billion, respectively.

AECOM TECHNOLOGY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

1. Significant Accounting Policies (Continued)

        Cost-Plus Contracts.    The Company enters into two major types of cost-plus contracts:

        Cost-Plus Fixed Fee.    Under cost-plus fixed fee contracts, the Company charges clients for its costs, including both direct and indirect costs, plus a fixed negotiated fee. The total estimated cost plus the fixed negotiated fee represents the total contract value. The Company recognizes revenue based on the actual labor and other direct costs incurred, plus the portion of the fixed fee it has earned to date.

        Cost-Plus Fixed Rate.    Under the Company's cost-plus fixed rate contracts, the Company charges clients for its direct and indirect costs based upon a negotiated rate. The Company recognizes revenue based on the actual total costs it has expended and the applicable fixed rate.

        Certain cost-plus contracts provide for award fees or a penalty based on performance criteria in lieu of a fixed fee or fixed rate. Other contracts include a base fee component plus a performance-based award fee. In addition, the Company may share award fees with subcontractors. The Company records accruals for fee-sharing as fees are earned. The Company generally recognizes revenue to the extent of costs actually incurred plus a proportionate amount of the fee expected to be earned. The Company takes the award fee or penalty on contracts into consideration when estimating revenue and profit rates, and it records revenue related to the award fees when there is sufficient information to assess anticipated contract performance. On contracts that represent higher than normal risk or technical difficulty, the Company may defer all award fees until an award fee letter is received. Once an award fee letter is received, the estimated or accrued fees are adjusted to the actual award amount.

        Certain cost-plus contracts provide for incentive fees based on performance against contractual milestones. The amount of the incentive fees varies, depending on whether the Company achieves above, at, or below target results. The Company originally recognizes revenue on these contracts based upon expected results. These estimates are revised when necessary based upon additional information that becomes available as the contract progresses.

Time-and-Materials Contracts.

        Time-and-Materials.    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 its actual out-of-pocket costs of materials and other direct incidental expenditures that it incurs in connection with its performance under the contract. 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. Many of the Company's time-and-materials contracts are subject to maximum contract values and, accordingly, revenue relating to these contracts is recognized as if these contracts were a fixed-price contract.

Fixed-Price Contracts.

        Firm Fixed-Price.    Fixed-price contracting is the predominant contracting method outside of the United States. There are typically two types of fixed-price contracts. The first and more common type, lump-sum, involves performing all of the work under the contract for a specified lump-sum fee. Lump-sum contracts are typically subject to price adjustments if the scope of the project changes or unforeseen conditions arise. The second type, fixed-unit price, involves performing an estimated number of units of work at an agreed price per unit, with the total payment under the contract determined by the actual number of units delivered. The Company recognizes revenue on firm fixed-price contracts using the

64

AECOM TECHNOLOGY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

1. Significant Accounting Policies (Continued)

percentage-of-completion method described above. Prior to completion, recognized profit margins on any firm fixed-price contract depend on the accuracy of the Company's estimates and will increase to the extent that its actual costs are below the estimated amounts. Conversely, if the Company's costs exceed these estimates, its profit margins will decrease and the Company may realize a loss on a project. The Company recognizes anticipated losses on contracts in the period in which they become evident.

Service-Related Contracts.

        Service-Related.    Service-related contracts, including operations and maintenance services and a variety of technical assistance services, are accounted for over the period of performance, in proportion to the costs of performance.

        Contract Claims—Claims are amounts in excess of the agreed contract price (or amounts not included in the original contract price) that the Company seeks to collect from customers or others for delays, errors in specifications and designs, contract terminations, change orders in dispute or unapproved as to both scope and price or other causes of unanticipated additional costs. The Company records contract revenue related to claims only if it is probable that the claim will result in additional contract revenue and if the amount can be reliably estimated. In such cases, the Company records revenue only to the extent that contract costs relating to the claim have been incurred. As of September 30, 2012 and 2011, the Company had no significant net receivables related to contract claims.

        Government Contract Matters—The Company's federal government and certain state and local agency contracts are subject to, among other regulations, regulations issued under the Federal Acquisition Regulations (FAR). These regulations can limit the recovery of certain specified indirect costs on contracts and subjects the Company to ongoing multiple audits by government agencies such as the Defense Contract Audit Agency (DCAA). In addition, most of the Company's federal and state and local contracts are subject to termination at the discretion of the client.

        Audits by the DCAA and other agencies consist of reviews of the Company's overhead rates, operating systems and cost proposals to ensure that the Company accounted for such costs in accordance with the Cost Accounting Standards of the FAR (CAS). If the DCAA determines the Company has not accounted for such costs consistent with CAS, the DCAA may disallow these costs. There can be no assurance that audits by the DCAA or other governmental agencies will not result in material cost disallowances in the future. See also Note 20.

        Cash and Cash Equivalents—The Company's cash equivalents include highly liquid investments which have an initial maturity of three months or less.

        Allowance for Doubtful Accounts—The Company records its accounts receivable net of an allowance for doubtful accounts. This allowance for doubtful accounts is estimated based on management's evaluation of the contracts involved and the financial condition of its clients. The factors the Company considers in its contract evaluations include, but are not limited to:

•

Client type—federal or state and local government or commercial client;

•

Historical contract performance;

•

Historical collection and delinquency trends;

65

AECOM TECHNOLOGY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

1. Significant Accounting Policies (Continued)

•

Client credit worthiness; and

•

General economic conditions.

        Derivative Financial Instruments—The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value.

        For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income in stockholders' equity and reclassified into income in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument, if any, is recognized in current income. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions.

        The net gain or loss on the effective portion of a derivative instrument that is designated as an economic hedge of the foreign currency translation exposure generated by the re-measurement of certain assets and liabilities denominated in a non-functional currency in a foreign operation is reported in the same manner as a foreign currency translation adjustment. Accordingly, any gains or losses related to these derivative instruments are recognized in current income.

        Derivatives that do not qualify as hedges are adjusted to fair value through current income.

        Fair Value of Financial Instruments—The Company determines the fair values of its financial instruments, including short-term investments, debt instruments and derivative instruments, and pension and post-retirement plan assets based on inputs or assumptions that market participants would use in pricing an asset or a liability. The Company categorizes its instruments using a valuation hierarchy for disclosure of the inputs used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value. The classification of a financial asset or liability within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

        The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short maturities of these instruments. The carrying amount of the revolving credit facility approximates fair value because the interest rates are based upon variable reference rates. See also Notes 10 and 12.

        The Company's fair value measurement methods may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Although the Company believes its valuation methods are appropriate and consistent with those used by other market participants, the use of different methodologies or assumptions to determine fair value could result in a different fair value measurement at the reporting date.

        Property and Equipment—Property and equipment are recorded at cost and are depreciated over their estimated useful lives using the straight-line method. Expenditures for maintenance and repairs are

66

AECOM TECHNOLOGY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

1. Significant Accounting Policies (Continued)

expensed as incurred. Typically, estimated useful lives range from three to ten years for equipment, furniture and fixtures. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the remaining terms of the underlying lease agreement.

        Long-lived Assets—Long-lived assets to be held and used are reviewed for impairment whenever events or circumstances indicate that the assets may be impaired. For assets to be held and used, impairment losses are recognized based upon the excess of the asset's carrying amount over the fair value of the asset. For long-lived assets to be disposed, impairment losses are recognized at the lower of the carrying amount or fair value less cost to sell.

        Goodwill and Acquired Intangible Assets—Goodwill represents the excess amounts paid over the fair value of net assets acquired from an acquisition. In order to determine the amount of goodwill resulting from an acquisition, the Company performs an assessment to determine the value of the acquired company's tangible and identifiable intangible assets and liabilities. In its assessment, the Company determines whether identifiable intangible assets exist, which typically include backlog and customer relationships.

        The Company tests goodwill at least annually for each reporting unit. A reporting unit is defined as an operating segment or one level below an operating segment. The Company's impairment tests are performed at the operating segment level as they represent the Company's reporting units.

        The impairment test is a two-step process. During the first step, the Company estimates the fair value of the reporting unit using income and market approaches, and compares that amount to the carrying value of that reporting unit. In the event the fair value of the reporting unit is determined to be less than the carrying value, a second step is required. The second step requires the Company to perform a hypothetical purchase allocation for that reporting unit and to compare the resulting current implied fair value of the goodwill to the current carrying value of the goodwill for that reporting unit. In the event that the current implied fair value of the goodwill is less than the carrying value, an impairment charge is recognized. See also Note 4.

        Pension Plans—The Company has certain defined benefit pension plans. The Company calculates the market-related value of assets, which is used to determine the return-on-assets component of annual pension expense and the cumulative net unrecognized gain or loss subject to amortization. This calculation reflects the Company's anticipated long-term rate of return and amortization of the difference between the actual return (including capital, dividends, and interest) and the expected return over a five-year period. Cumulative net unrecognized gains or losses that exceed 10% of the greater of the projected benefit obligation or the market related value of plan assets are subject to amortization.

        Insurance Reserves—The Company maintains insurance for certain insurable business risks. Insurance coverage contains various retention and deductible amounts for which the Company accrues a liability based upon reported claims and an actuarially determined estimated liability for certain claims incurred but not reported. It is the Company's policy not to accrue for any potential legal expense to be incurred in defending the Company's position. The Company believes that its accruals for estimated liabilities associated with professional and other liabilities are sufficient and any excess liability beyond the accrual is not expected to have a material adverse effect on the Company's results of operations or financial position.

        Foreign Currency Translation—The Company's functional currency is the U.S. dollar. Results of operations for foreign entities are translated to U.S. dollars using the average exchange rates during the

67

AECOM TECHNOLOGY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

1. Significant Accounting Policies (Continued)

period. Assets and liabilities for foreign entities are translated using the exchange rates in effect as of the date of the balance sheet. Resulting translation adjustments are recorded as a foreign currency translation adjustment into other accumulated comprehensive income/(loss) in stockholders' equity.

        The Company uses foreign currency forward contracts from time to time to mitigate foreign currency risk. The Company limits exposure to foreign currency fluctuations in most of its contracts through provisions that require client payments in currencies corresponding to the currency in which costs are incurred. As a result of this natural hedge, the Company generally does not need to hedge foreign currency cash flows for contract work performed. The functional currency of all significant foreign operations is the respective local currency.

        Income Taxes—The Company files a consolidated federal income tax return and combined / consolidated state tax returns and separate company state tax returns. The Company accounts for certain income and expense items differently for financial reporting and income tax purposes. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the differences are expected to reverse. In determining the need for a valuation allowance, management reviews both positive and negative evidence, including current and historical results of operations, future income projections, and potential tax planning strategies. Based upon management's assessment of all available evidence, the Company has concluded that it is more likely than not that the deferred tax assets, net of valuation allowance, will be realized.

2. New Accounting Pronouncements and Changes in Accounting

        In January 2010, the Financial Accounting Standards Board (FASB) issued guidance to amend the disclosure requirements related to fair value measurements. The Company adopted this guidance for the quarter ended March 31, 2010, except for the portion of the guidance that requires the disclosure of activities on purchases, sales, issuance, and settlements of the assets and liabilities measured using significant unobservable inputs (Level 3 fair value measurements). The Level 3 fair value measurement guidance was adopted by the Company in its fiscal year beginning October 1, 2011. Since the Company carried no material Level 3 assets or liabilities during the period, the adoption of the separate disclosures related to Level 3 measurements did not have a material impact on its consolidated financial statements. Additionally, the FASB issued a new accounting standard on fair value measurements that changes certain fair value measurement principles, clarifies the requirement for measuring fair value and expands disclosure requirements, particularly for Level 3 fair value measurements. This guidance was effective for the Company in its second quarter ending March 31, 2012 and did not have a material impact on its consolidated financial statements.

        In June 2011, the FASB issued guidance on the presentation of comprehensive income. The new standard will require companies to present items of net income, items of other comprehensive income and total comprehensive income in one continuous statement or two separate consecutive statements, and companies will no longer be allowed to present items of other comprehensive income in the statement of stockholders' equity. This guidance is effective for the Company in its fiscal year beginning October 1, 2012 and, although it will change the financial statement presentation, it is not expected to have a material impact on its financial condition or results of operations.

2. New Accounting Pronouncements and Changes in Accounting (Continued)

        In September 2011, the FASB issued guidance intended to simplify goodwill impairment testing. Entities are allowed to 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 as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. This guidance is effective for goodwill impairment tests performed in interim and annual periods for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company does not expect this guidance will have a material impact on its consolidated financial statements.

3. Stock Repurchase Program

        In August 2011, the Company's Board of Directors authorized a stock repurchase program (the Repurchase Program), pursuant to which the Company could initially purchase up to $200 million of its common stock. Share repurchases under this program can be made through open market purchases, unsolicited or solicited privately negotiated transactions or other methods, including pursuant to a Rule 10b5-1 plan. The Company completed the initial authorization to purchase $200 million of its common stock during the quarter ended June 30, 2012.

Accelerated Share Repurchase

        In connection with the Repurchase Program, the Company entered into an accelerated share repurchase (ASR) agreement with Bank of America, N.A. (Bank of America) on August 16, 2011. Under the ASR agreement, the Company agreed to repurchase $100 million of its common stock from Bank of America. During the quarter ended September 30, 2011, Bank of America delivered 4.3 million shares to the Company, at which point the Company's shares outstanding were reduced and accounted for as a reduction to retained earnings. The number of shares delivered was the minimum amount of shares Bank of America is contractually obligated to provide under the ASR agreement.

        The number of shares that ultimately were repurchased by the Company under the ASR agreement was based upon the volume-weighted average share price of the Company's common stock during the term of the ASR agreement, less an agreed discount, subject to collar provisions which established a maximum and minimum price and other customary conditions under the ASR agreement. The ASR agreement was settled in full on March 7, 2012 and the total number of shares repurchased was 4.8 million at an average price of $20.97.

Rule 10b5-1 Repurchase Plan and Open Market Purchases

        In connection with the Repurchase Program, the Company entered into two Rule 10b5-1 repurchase plans. The timing, nature and amount of purchases depended on a variety of factors, including market conditions and the volume limit defined by Rule 10b-18.

        As of June 30, 2012, the Company had repurchased approximately 4.4 million shares under both the Rule 10b5-1 plans and open market purchases, at an average price of $22.59, for a total cost of approximately $100.0 million; thereby completing its initial authorization under the Repurchase Program.

3. Stock Repurchase Program (Continued)

$300 million share repurchase authorization

        In August 2012, the Company's Board of Directors authorized an additional $300 million to repurchase its common stock under the Repurchase Program. As of September 30, 2012, the Company repurchased under open market purchases and purchases made under a Rule 10b5-1 plan, 3.0 million shares at an average price of $20.71, for a total cost of $62.3 million, which included 0.5 million shares repurchased in transactions that were settled in fiscal 2013. As of September 30, 2012, $237.7 million of shares remained available for repurchase pursuant to this repurchase program. Repurchased shares are retired, but remain authorized for registration and issuance in the future.

4. Business Acquisitions, Goodwill, and Intangible Assets

        The Company completed one, six, and six business acquisitions during the years ended September 30, 2012, 2011 and 2010, respectively. Business acquisitions completed during the years ended September 30, 2012, 2011 and 2010 did not meet the quantitative thresholds to require proforma disclosures of operating results, either individually or in the aggregate, based on the Company's consolidated assets, investments and net income.

        Business acquisitions during the year ended September 30, 2012 included an environmental engineering firm in Asia.

        Business acquisitions during the year ended September 30, 2011 included four separate global cost and project management consultancy firms that operated under the Davis Langdon name, including businesses in Europe and Middle East, Australia and New Zealand, Africa, and North America. Each of the four acquisitions were separately negotiated, executed by separate purchase agreements, with no one acquisition contingent upon the other, and the businesses, although operating as part of a Swiss Verein, under which they shared certain naming and marketing rights, were not under common control or management. Business acquisitions for the year ended September 30, 2011 also included RSW, Inc., an international engineering firm based in Montreal, Quebec, Canada and Spectral Services Consultants Pte. Ltd. (Spectral), a building services consultancy in India.

        Business acquisitions during the year ended September 30, 2010 included Tishman Construction Corporation (Tishman), a New York based provider of construction management services in the United States and the United Arab Emirates, and MT Holdings Corporation, the parent of McNeil Technologies, Inc. (McNeil), a government national security and intelligence services firm based in Virginia.

        The aggregate value of all consideration for acquisitions consummated during the years ended September 30, 2012, 2011 and 2010 were $15.4 million, $453.3 million and $768.0 million, respectively. The

Equity issued		0.9		68.5		65.3
Total consideration	$	15.4	$	453.3	$	768.0

        All of the above acquisitions were accounted for under the acquisition method of accounting. As such, the purchase consideration of each acquired company was allocated to acquired tangible and intangible assets and liabilities based upon their fair values. The excess of the purchase consideration over the fair value of the net tangible and identifiable intangible assets acquired was recorded as goodwill. The results of operations of each company acquired have been included in the Company's financial statements from the date of acquisition.

        At the time of acquisition, the Company preliminarily estimates the amount of the identifiable intangible assets acquired based upon historical valuations of similar acquisitions and the facts and

circumstances available at the time. 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.

        During the fourth quarter of the year ended September 30, 2012, the Company conducted its annual goodwill impairment test. The impairment evaluation process includes, among other things, making assumptions about variables such as revenue growth rates, profitability, discount rates, and industry market multiples, which are subject to a high degree of judgment. As a result of the first step of the impairment analysis, due to market conditions and business trends within the Europe, Middle East, and Africa (EMEA) and MSS reporting units, the Company determined that goodwill was impaired. The second step of the analysis is performed to measure the impairment as the excess of the goodwill carrying value over its implied fair value. This analysis resulted in an impairment of $336.0 million, or $317.2 million, net of tax.

        The changes in the carrying value of goodwill by reportable segment for the fiscal years ended September 30, 2012, 2011 and 2010 were as follows:

	Fiscal Year 2012
	September 30, 2011		Post- Acquisition Adjustments			Foreign Exchange Impact		Acquired		Goodwill Impairment			September 30, 2012

6. Accounts Receivable—Net (Continued)

        Billed accounts receivable represent amounts billed to clients that have yet to be collected. Unbilled accounts receivable represents the contract revenue recognized but not yet billed pursuant to contract terms or accounts billed after the period end. Substantially all unbilled receivables as of September 30, 2012 and 2011 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, other contractual conditions or upon the completion of the 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 September 30, 2012 and 2011.

        The Company sold trade receivables to a financial institution, of which $31.2 million was outstanding as of September 30, 2012. The Company does not retain financial or legal interest in these receivables.

7. Property and Equipment

        Property and equipment, at cost, consists of the following:

	Fiscal Year Ended
	September 30, 2012			September 30, 2011			Useful Lives (years)

Total		676.3			648.1
Accumulated depreciation and amortization		(350.4	)		(324.3	)
Property and equipment, net	$	325.9		$	323.8

        Depreciation expense for the fiscal years ended September 30, 2012, 2011 and 2010 were $77.1 million, $73.2 million and $59.3 million, respectively. Included in depreciation expense is amortization of capitalized software costs in the years ended September 30, 2012, 2011 and 2010 of $6.2 million, $6.7 million and $5.8 million, respectively. Unamortized capitalized software costs at September 30, 2012, 2011 and 2010 were $24.1 million, $20.9 million and $20.7 million, respectively.

        Depreciation and amortization are provided using primarily the straight-line method over the estimated useful lives of the assets, or in the case of leasehold improvements and capitalized leases, the lesser of the remaining life of the lease or its estimated useful life.

8. 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 a representative 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's economics.

        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 entities, 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 result 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 which provide a party the power to direct the activities that most significantly impact the joint ventures' 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 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.

        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 20.

9. Pension Plans

        In the U.S., the Company sponsors a Defined Benefit Pension Plan (the Pension Plan) which covers substantially all permanent employees hired as of March 1, 1998, subject to eligibility and vesting requirements, and required contributions from participating employees through March 31, 1998. Benefits under this plan generally are based on the employee's years of creditable service and compensation. Effective April 1, 2004, the Company set a maximum on the amount of compensation used to determine pension benefits based on the highest calendar year of compensation earned in the 10 completed calendar years from 1994 through 2003, or the relevant IRS annual compensation limit, $200,000, whichever is lower. Outside the U.S., the Company sponsors various pension plans, which are appropriate to the country in which the Company operates, some of which are government mandated.

        During the quarter ended December 31, 2009, the Company adopted an amendment to freeze pension plan benefit accruals for certain U.S. employee plans resulting in a curtailment gain of $1.9 million. During the quarter ended March 31, 2011, the Company adopted an amendment to freeze pension plan benefit accruals for certain U.K. and Ireland employee plans resulting in a curtailment gain of $4.2 million.

        The Company's policy is to minimize the risk of large losses through diversification in a portfolio of stocks, bonds, and cash equivalents, as appropriate, which may reflect varying rates of return. The percentage of assets allocated to cash is to assure liquidity to meet benefit disbursements and general operating expenses.

        To develop the expected long-term rate of return on assets assumption, the Company considered the historical returns and the future expectations for returns for each asset class, as well as the target asset allocation of the pension portfolio and the diversification of the portfolio. This resulted in the selection of a 7.5% and 5.7% weighted-average long-term rate of return on assets assumption for the fiscal year ended September 30, 2012 for U.S. and non-U.S. plans, respectively.

        Cash equivalents are mostly comprised of short-term money-market instruments and are valued at cost, which approximates fair value.

        For equity investment funds not traded on an active exchange, or if the closing price is not available, the trustee obtains indicative quotes from a pricing vendor, broker, or investment manager. These funds are categorized as Level 2 if the custodian obtains corroborated quotes from a pricing vendor or categorized as Level 3 if the custodian obtains uncorroborated quotes from a broker or investment manager.

        Fixed income investment funds categorized as Level 2 are valued by the trustee using pricing models that use verifiable observable market data (e.g., interest rates and yield curves observable at commonly quoted intervals), bids provided by brokers or dealers, or quoted prices of securities with similar characteristics.

        Hedge funds categorized as Level 3 are valued based on valuation models that include significant unobservable inputs and cannot be corroborated using verifiable observable market data. Hedge funds are valued by independent administrators. Depending on the nature of the assets, the general partners or independent administrators use both the income and market approaches in their models. The market approach consists of analyzing market transactions for comparable assets while the income approach uses earnings or the net present value of estimated future cash flows adjusted for liquidity and other risk factors. As of September 30, 2012, there were no material changes to the valuation techniques.

Unsecured Term Credit Agreements

        In September 2011, the Company entered into an Amended and Restated Credit Agreement (the "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 in term loans on the closing date and may borrow up to an additional $100 million in term loans upon request by the Company subject to certain conditions, including Company and lender approval. The Company used approximately $600 million of the proceeds from the loans to repay indebtedness under its prior term loan facility, approximately $147 million of the proceeds to pay down indebtedness under its revolving credit facility and a portion of the proceeds to pay fees and expenses related to the Term Credit Agreement. 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 0.375% to 1.50% and the applicable margin for Eurodollar Rate loans is a range of 1.375% to 2.50%, both based on the debt-to-earnings leverage ratio of the Company at the end of each fiscal quarter. The initial interest rate of the loans borrowed on September 30, 2011 was the 3 month Eurodollar rate plus 1.75%, or a total of 2.12%. For the years ended September 30, 2012 and 2011, the average interest rate of the Company's term loan facility was 2.19% and 3.01%, respectively. Payments of the initial principal amount outstanding under the Term Credit Agreement are required on a quarterly basis beginning on December 31, 2012, while interest payments are made on a quarterly basis beginning December 31, 2011. Any remaining principal of the loans under the Term Credit Agreement is due no later than July 20, 2016. Accrued interest is payable in arrears on a quarterly basis for Base Rate loans, and at the end of the applicable interest period (but at least every three months) for Eurodollar Rate loans. The Company may optionally prepay the loans at any time, without penalty.

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 was $81.8 million and $78.6 million at September 30, 2012 and 2011, respectively, which have an effective interest rate of 5.62%. The fair value of the Company's unsecured senior notes was approximately $277.8 million at September 30, 2012 and $259.2 million at September 30,

2011. 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.

Unsecured Revolving Credit Facility

        In July 2011, the Company entered into a Third Amended and Restated Credit Agreement (the "Revolving Credit Agreement") with Bank of America, N.A., as an administrative agent and a lender and the other lenders party thereto, which amended and restated its unsecured revolving credit facility and increased its available borrowing capacity to $1.05 billion in order to support its working capital and acquisition needs. The Revolving Credit Agreement has an expiration date of July 20, 2016 and prior to this expiration date, principal amounts outstanding under the Revolving Credit Agreement may be repaid and reborrowed at the option of the Company without prepayment or penalty, subject to certain conditions. The Company may also, at its option, request an increase in the commitments under the facility up to a total of $1.15 billion, subject to certain conditions, including Company and lender approval. 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 0.0% to 1.50% and the applicable margin for the Eurocurrency Rate loans is a range of 1.00% to 2.50%, 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 0.150% to 0.375% on any unused commitment. Accrued interest is payable in arrears on a quarterly basis for Base Rate loans, and at the end of the applicable interest period (but at least every three months) for Eurocurrency Loans. At September 30, 2012 and 2011, $24.0 million and $101.4 million, respectively, were outstanding under the revolving credit facility. At September 30, 2012 and 2011, outstanding standby letters of credit totaled $35.1 million and $32.1 million, respectively, under the revolving credit facility. As of September 30, 2012, the Company had $990.9 million available under its Revolving Credit Agreement.

Covenants and Restrictions

        Under the Company's debt agreements relating to its unsecured revolving credit facility and unsecured term credit agreements, the Company is subject to a maximum consolidated leverage ratio at the end of any fiscal quarter. This ratio is calculated by dividing consolidated funded debt (including financial letters of credit) by consolidated earnings before interest, taxes, depreciation, and amortization (EBITDA). For 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 the Company's acquisitions). As of September 30, 2012, the consolidated leverage ratio was 2.15, which did not exceed the Company's most restrictive maximum consolidated leverage ratio 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 ended 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 September 30, 2012, this amount was $2.2 billion, which exceeds the calculated threshold of $1.5 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 September 30, 2012 and 2011, 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, refer to Note 11 herein for additional information regarding the Company's interest rate swap agreements, during the years ended September 30, 2012 and 2011 was 3.1% and 3.3%, respectively.

Notes Secured by Real Properties

        Notes secured by real properties, payable to a bank, were assumed in connection with a business acquired during the year ended September 30, 2008. These notes payable bear interest at 6.04% per annum and mature in December 2028.

Other Debt

        Other debt consists primarily of bank overdrafts and obligations under capital leases. In addition to the unsecured revolving credit facility discussed above, at September 30, 2012, the Company had $470.1 million of unsecured credit facilities primarily used to cover periodic overdrafts and standby letters of credit, of which $209.8 million was utilized for outstanding standby letters of credit.

11. 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.

AECOM TECHNOLOGY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

11. Derivative Financial Instruments (Continued)

        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 operations as cost of revenue, interest expense, net, 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, net when the interest expense on the variable rate debt is recognized, or to cost of sales 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 sales.

        At September 30, 2012, the effective portion of our interest rate swap agreements designated as cash flow hedges before tax effect was $6.2 million, of which $2.9 million is expected to be reclassified from accumulated other comprehensive loss to interest expense, net within the next 12 months. At September 30, 2012, the effective portion of the Company's foreign currency options designated as cash flow hedges before tax effect, were immaterial.

        As of September 30, 2012, the notional principal, fixed rates and related expiration dates of the Company's outstanding interest rate swap agreements are as follows:

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

        As of September 30, 2011, the notional principal, fixed rates and related expiration dates of the Company's outstanding interest rate swap agreements are as follows:

Notional Amount (in millions)		Fixed Rate			Expiration Date
$	250.0		0.95	%	September 2015

        The notional principal of foreign currency options to purchase British Pounds (GBP) with Brazilian Reais (BRL) was BRL 16.4 million (or approximately $8.1 million) at September 30, 2012. These foreign exchange contracts have maturities of 24 months or less. The Company had no foreign currency options outstanding at September 30, 2011.

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 sales for those instruments related to the provision of our 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 $60.1 million at September 30, 2012. The notional principal of foreign currency forward contracts to sell U.S. dollars for foreign currencies was $110.2 million at September 30, 2012. The notional principal of foreign currency forward contracts to purchase GBP with BRL was BRL 9.7 million (or approximately $4.9 million) at September 30, 2012.

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 sales. 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 sales. The notional principal of option contracts to sell U.S. dollars for foreign currencies was $17.3 million at September 30, 2012 and no such option contracts were outstanding at September 30, 2011.

12. 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.

91

AECOM TECHNOLOGY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

12. Fair Value Measurements (Continued)

        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 year ended September 30, 2012, the Company recognized an impairment of goodwill within both its PTS and MSS reportable segments. For further information regarding the impairment of goodwill refer to Note 4 herein. During the year ended September 30, 2011, the Company did not record any fair market 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 may be used to measure fair value, as discussed in Note 1. There were no significant transfers between any of the levels of the fair value hierarchy during the years ended September 30, 2012 and 2011. The Company classifies its derivative financial instruments within Level 2 as the valuation inputs are based on quoted prices and market observable data of similar instruments.

        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:

	September 30, 2012		Quoted Prices in Active Markets for Similar Assets (Level 2)
Foreign currency options	$	0.1	$	0.1
Option contracts		0.1		0.1

        For additional information about the Company's derivative financial instruments refer to Note 11 herein.

13. Concentration of Credit Risk

        Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of temporary cash investments and trade receivables. The Company's cash balances and short-term investments are maintained in accounts held by major banks and financial institutions located primarily in the U.S., Canada, Europe, Australia, Middle East and Hong Kong. If the Company extends a significant portion of its credit to clients in a specific geographic area or industry, the Company may

92

AECOM TECHNOLOGY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

13. Concentration of Credit Risk (Continued)

experience disproportionately high levels of default if those clients are adversely affected by factors particular to their geographic area or industry. Concentrations of credit risk with respect to trade receivables are limited due to the large number of customers comprising the Company's customer base, including, in large part, governments, government agencies and quasi-government organizations, and their dispersion across many different industries and geographies. See Note 21 regarding the Company's foreign revenues. In order to mitigate credit risk, the Company continually reviews the credit worthiness of its major private clients.

14. Leases

        The Company and its subsidiaries are lessees in non-cancelable leasing agreements for office buildings and equipment which expire at various dates. The related lease payments are expensed on a straight-line basis over the lease term, including, as applicable, any free-rent period during which the Company has the right to use the asset. For leases with renewal options where the renewal is reasonably assured, the lease term, including the renewal period is used to determine the appropriate lease classification and to compute periodic rental expense. The following table presents, in millions, amounts payable under non-cancelable operating lease commitments during the following fiscal years:

Year Ending September 30,
2013	$	201.6
2014		175.7
2015		139.6
2016		122.1
2017		100.4
Thereafter		319.9
Total	$	1,059.3

        Included in the above table are commitments totaling $17.0 million related to the sale-leaseback of the Company's Orange, California facility initially entered into during the year ended September 30, 2006. The sales price of this facility was $20.1 million of which $16.3 million in gain on sale-leaseback was deferred and is being amortized over the 12-year term of the lease.

        The Company also has similar non-cancelable leasing agreements that are accounted for as capital lease obligations due to the terms of the underlying leases. At September 30, 2012 and 2011, the Company had total lease obligations under capital leases of $5.9 million and $8.0 million, respectively. Rent expense for all leases for the years ended September 30, 2012, 2011 and 2010, was approximately $237.4 million, $254.5 million and $211.3 million, respectively. When the Company is required to restore leased facilities to original condition, provisions are made over the period of the lease.

16. Stockholders' Equity

        Common Stock Units—Common stock units are only redeemable for common stock. In the event of liquidation of the Company, holders of stock units are entitled to no greater rights than holders of common stock. See also Note 17.

        Class E Preferred Stock—The Class E Preferred Stock is limited to an aggregate of 20 shares, has no par value, and has a liquidation preference of $1.00 per share. Holders of these shares are entitled to 100,000 votes per share on all matters voted on by holders of Class E Preferred Stock. The Company, with notice,

94

AECOM TECHNOLOGY CORPORATION

16. Stockholders' Equity (Continued)

may redeem Class E Preferred Stock by paying the liquidation preference. The holders of Class E Preferred Stock have no conversion rights. All shares of Class E Preferred Stock redeemed or repurchased by the Company will be restored to the status of authorized but un-issued shares of Preferred Stock, without designation as to series.

17. Stock Plans

        Defined Contribution Plans—Substantially all permanent employees are eligible to participate in defined contribution plans provided by the Company. Under these plans, participants may make contributions into a variety of funds, including a fund that is fully invested in Company stock. Employees are not required to allocate any funds to Company stock, which allows employees to limit their exposure to market changes in the Company's stock price. Employees may generally reallocate their account balances on a daily basis. The only limit on the frequency of reallocations applies to changes involving Company stock investments by employees classified as insiders or restricted personnel under the Company's insider trading policy.

        Deferred Compensation Plan—In the past, the Company sponsored the Deferred Compensation Plan (DCP), a stock purchase plan that provided an opportunity for eligible employees and non-employee directors to continue to invest in the Company when the Company's qualified plans were no longer available to them due to limitations contained in the U.S. Internal Revenue Code. Under the DCP, participants were permitted to defer compensation, on a pre-tax basis, for investment in common stock units. The Company funded a rabbi trust for certain diversified DCP balances in connection with the initial public offering in May 2007. The Company elected to terminate this plan effective in December 2009. As a result of the termination, 6.3 million outstanding restricted stock units and the Company's deferred compensation liability of $88.8 million as of September 30, 2010 were settled in December 2010. Investments in the rabbi trust totaled $67.2 million as of September 2010, which were substantially used to settle the liability.

        Compensation expense relating to employer contributions under defined contribution plans, including the DCP, for fiscal years ended September 30, 2012, 2011 and 2010 was $15.9 million, $17.2 million and $15.8 million, respectively. Issuances and repurchases of AECOM common stock related to employee participants' contributions to and withdrawals from these defined contribution plans are included as issuances and repurchases of stock in the accompanying Consolidated Statements of Stockholders' Equity and of Cash Flows.

        Stock Incentive Plans—Under the 2006 Stock Incentive Plan, the Company has 15.7 million securities remaining available for future issuance under stock options or restricted stock awards as of September 30, 2012. Stock options may be granted to employees and non-employee directors with an exercise price not less than the fair market value of the stock on the date of grant. Unexercised options expire seven years after date of grant. During the years ended September 30, 2012, 2011 and 2010, compensation expense recognized relating to employee stock options as a result of the fair value method was $2.4 million, $4.6 million and $4.1 million, respectively. Unrecognized compensation expense relating to employee stock options outstanding as of September 30, 2012 was $1.3 million to be recognized on a straight-line basis over the awards' respective vesting periods which are generally three years.

The aggregate intrinsic value of stock options exercised during the years ended September 30, 2012, 2011 and 2010 was $3.9 million, $7.8 million and $17.9 million, respectively.

        The Company grants stock units to employees under the Performance Earnings Program (PEP), whereby units are earned and issued dependent upon meeting established cumulative performance objectives over a three-year period. The Company recognized compensation expense relating to the PEP of $3.2 million, $7.3 million and $22.3 million during the years ended September 30, 2012, 2011 and 2010, respectively. Additionally, the Company issues restricted stock units, which are earned based on service conditions, resulting in compensation expenses of $20.9 million, $13.1 million and $7.5 million during the years ended September 30, 2012, 2011 and 2010, respectively. Unrecognized compensation expense related to PEP units and restricted stock units outstanding as of September 30, 2012 was $7.1 million and $30.6 million, respectively, to be recognized on a straight-line basis over the awards' respective vesting periods which are generally three years.

        Cash flow 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 $1.3 million, $61.2 million and $17.3 million for the years ended September 30, 2012, 2011 and 2010, respectively, have been classified as financing cash inflows in the Condensed Consolidated Statements of Cash Flows.

        As of September 30, 2012, the Company has available unused state net operating loss (NOL) carry forwards of $257.3 million and foreign NOL carry forwards of $201.9 million which expire at various dates through 2031. In addition, as of September 30, 2012, the Company has available unused federal research and development credits of $12.7 million, which expire at various dates through 2031, unused state research and development credits of $11.5 million and California Enterprise Zone Tax Credits of $2.0 million which can be carried forward indefinitely.

        As of September 30, 2012 and 2011, gross deferred tax assets were $376.4 million and $351.3 million, respectively. The Company has recorded a valuation allowance of approximately $19.2 million and $17.8 million at September 30, 2012 and 2011, respectively, related to state and foreign net operating loss carry forwards and credits. The Company has performed an assessment of positive and negative evidence regarding the realization of the net deferred tax asset in accordance with ASC 740-10, "Accounting for Income Taxes." This assessment included the evaluation of scheduled reversals of deferred tax liabilities, the availability of carry forwards and estimates of projected future taxable income. Although realization is not assured, based on the Company's assessment, the Company has concluded that it is more likely than not that the remaining asset of $357.2 million will be realized and, as such, no additional valuation allowance has been provided.

        As of September 30, 2012 and September 30, 2011, the Company has remaining tax-deductible goodwill of $306.6 million and $343.2 million, respectively, resulting from acquisitions. The amortization of this goodwill is deductible over various periods ranging up to 15 years.

        The Company does not provide for U.S. taxes or foreign withholding taxes on undistributed earnings from non-U.S. subsidiaries because such earnings are intended to be reinvested indefinitely. The undistributed earnings are approximately $797.4 million. If undistributed pre-tax earnings were distributed, foreign tax credits could become available under current law to reduce the resulting U.S. income tax liability.

        As of September 30, 2012, the Company had a liability for unrecognized tax benefits, including potential interest and penalties, net of related tax benefit, totaling $56.3 million. The gross unrecognized tax benefits as of September 30, 2012 and 2011 were $55.8 million and $58.1 million, respectively, excluding interest, penalties, and related tax benefit. Of the $55.8 million, approximately $50.8 million, including related tax benefits, would be included in the effective tax rate if recognized in the fiscal year ended September 30, 2012. The adoption of ASC 805, "Accounting for Business Combinations," at the beginning of the fiscal year ended September 30, 2010 changed the treatment of the reversal of unrecognized tax benefits related to acquired companies which prior to adoption of ASC 805 would have impacted goodwill, but after the adoption of ASC 805, results in the recognition of income tax benefit. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows:

        The Company classifies interest and penalties related to uncertain tax positions within the income tax expense line in the accompanying consolidated statements of operations. At September 30, 2012, the accrued interest and penalties were $9.6 million and $0.1 million, respectively, excluding any related income tax benefits. As of September 30, 2011, the accrued interest and penalties were $10.5 million and $0.1 million, respectively, excluding any related income tax benefits.

        The Company files income tax returns in numerous tax jurisdictions, including the U.S., and numerous U.S. states and non-U.S. jurisdictions around the world. The statute of limitations varies by jurisdiction in which the Company operates. Because of the number of jurisdictions in which the Company files tax returns, in any given year the statute of limitations in certain jurisdictions may expire without examination within the 12-month period from the balance sheet date. With few exceptions, the Company is no longer subject to U.S. (including federal, state and local) or non-U.S. income tax examinations by tax authorities for years before fiscal year 2006.

19. 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 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 computation of diluted loss per share for the year ended September 31, 2012 excludes 0.7 million of potential common shares due to their antidilutive effect.

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

	Fiscal Year Ended
	September 30, 2012		September 30, 2011		September 30, 2010
	(in millions)
Denominator for basic earnings per share		111.9		117.4		114.3
Potential common shares		—		0.9		1.2
Denominator for diluted earnings per share		111.9		118.3		115.5

        As discussed in Note 3, EPS includes the effect of repurchased shares. For the years ended September 30, 2011 and 2010, options excluded from the calculation of potential common shares were not significant.

20. 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 operations 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 September 30, 2012, the Company was contingently liable in the amount of approximately $244.9 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

20. Commitments and Contingencies (Continued)

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. 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 operations or cash flows.

Combat Support Associates Joint Venture

        As of September 30, 2012, the Company has settled the previously disclosed Combat Support Associates Defense Contract Audit Agency (DCAA) Form 1 matter.

Global Linguists Solutions Joint Venture

        On October 5, 2011 and February 8, 2012, the DCAA issued DCAA Forms 1 questioning costs incurred by Global Linguists Solutions (GLS), an equity method joint venture, of which McNeil Technologies, Inc., acquired by the Company in August 2010, is an owner. The questioned costs were incurred by GLS during fiscal 2009, a period prior to the acquisition. Specifically, the DCAA questioned direct labor, associated burdens, and fees billed to the U.S. Government for linguists that allegedly did not meet specific contract requirements. As a result of the issuance of the DCAA Forms 1, the U.S. Government has withheld approximately $19 million from payments on current year billings pending final resolution.

        GLS is performing a review of the issues raised in the Forms 1 in order to respond fully to the questioned costs. Based on a review, GLS believes that the costs met the applicable contract requirements.

        Additionally, on April 20, 2012, GLS received a subpoena from the Inspector General of the U.S. Department of Defense requesting documentation related to this contract with the United States Army. GLS plans to respond fully to the request. If the DCAA Forms 1 are not overruled and subsequent appeals are unsuccessful or there are unfavorable consequences from the Inspector General's investigation, these events could have a material adverse effect on the Company's results of operations.

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 a special purpose vehicle (SPV) that raised approximately $700 million Australian dollars through an initial public offering (IPO) of equity units in 2006 and another approximately $1.4 billion Australian dollars in long term bank loans. The SPV (and certain affiliated SPVs) went into insolvency administrations in February 2011.

20. Commitments and Contingencies (Continued)

        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. Separately, KordaMentha, the receivers for the SPVs, filed a lawsuit in the Federal Court of Australia on May 14, 2012 claiming damages that purportedly resulted from AECOM Australia's role in connection with the above described traffic forecast. WestLB, one of the lending banks to the SPVs, filed a lawsuit in the Federal Court of Australia on May 18, 2012. Centerbridge Credit Partners (and a number of related entities) and Midtown Acquisitions (and a number of related entities), both claiming to be assignees of certain other lending banks, previously filed their own proceedings in the Federal Court of Australia and then subsequently withdrew the lawsuits. None of the lawsuits specify the amount of damages sought and the damages sought by WestLB are duplicative of damages already included in the receivers' claim.

        AECOM Australia intends to vigorously defend the claims brought against it.

Hawaii Project

        The U.S. Attorney's Office (USAO) informed us that the USAO and the U.S. Environmental Protection Agency are investigating potential criminal charges in connection with services our subsidiary provided to the operator of the Waimanalo Gulch Sanitary Landfill in Hawaii. The Company has cooperated fully with the investigation and, as of this date, no actions have been filed. The Company believes that the investigation will show that there has been no criminal wrongdoing on our part or any of our subsidiaries and, if any actions are brought, the Company intends to vigorously defend against such actions.

        The services performed by the subsidiary included the preparation of a pollution control plan, which the operator used to obtain permits necessary for the operation of the landfill. The USAO is investigating whether flooding at the landfill that resulted in the discharge of waste materials and storm water into the Pacific Ocean in December 2010 and January 2011 was due in part to reliance on information contained in the plan prepared by a subsidiary of the Company.

21. Reportable Segments and Geographic Information

        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 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.

ITEM 9A.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

        Our management, with the participation of our CEO and CFO, are responsible for establishing and maintaining "disclosure controls and procedures" (as defined in Rule 13a-15(e) under the Exchange Act) for our company. Based on their evaluation as of the end of the period covered by this report, our CEO and CFO have concluded that our disclosure controls and procedures were effective to ensure that the information required to be disclosed by us in this Annual Report on Form 10-K was (i) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and (ii) accumulated and communicated to our management, including our principal executive and principal financial officers, to allow timely decisions regarding required disclosures.

Management's Report on Internal Control over Financial Reporting

        Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934, as amended, as a process designed by, or under the supervision of, the company's principal executive and principal financial officers and effected by the company's board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of the effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        Our management, with the participation of our CEO and CFO, assessed the effectiveness of our internal control over financial reporting as of September 30, 2012, the end of our fiscal year. Our management based its assessment on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Our management's assessment included evaluation and testing of the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment.

        Based on our management's assessment, our management has concluded that our internal control over financial reporting was effective as of September 30, 2012. Our management communicated the results of its assessment to the Audit Committee of our Board of Directors.

        Our independent registered public accounting firm, Ernst & Young LLP, audited our financial statements for the fiscal year ended September 30, 2012 included in this Annual Report on Form 10-K, and

109

has issued an attestation report on our assessment of the Company's internal control over financial reporting, a copy of which is included earlier in this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

        Our management, including our CEO and CFO, confirm that there were no changes in our company's internal control over financial reporting during the fiscal quarter ended September 30, 2012 that have materially affected, or are reasonably likely to materially affect, our company's internal control over financial reporting.

Earnings Per Share

Earnings Per Share

19. 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 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 computation of diluted loss per share for the year ended September 31, 2012 excludes 0.7 million of potential common shares due to their antidilutive effect.

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

	Fiscal Year Ended
	September 30, 2012		September 30, 2011		September 30, 2010
	(in millions)
Denominator for basic earnings per share		111.9		117.4		114.3
Potential common shares		—		0.9		1.2
Denominator for diluted earnings per share		111.9		118.3		115.5

        As discussed in Note 3, EPS includes the effect of repurchased shares. For the years ended September 30, 2011 and 2010, options excluded from the calculation of potential common shares were not significant.

Stock Repurchase Program

Stock Repurchase Program

Stock Repurchase Program

3. Stock Repurchase Program

        In August 2011, the Company's Board of Directors authorized a stock repurchase program (the Repurchase Program), pursuant to which the Company could initially purchase up to $200 million of its common stock. Share repurchases under this program can be made through open market purchases, unsolicited or solicited privately negotiated transactions or other methods, including pursuant to a Rule 10b5-1 plan. The Company completed the initial authorization to purchase $200 million of its common stock during the quarter ended June 30, 2012.

• Accelerated Share Repurchase

        In connection with the Repurchase Program, the Company entered into an accelerated share repurchase (ASR) agreement with Bank of America, N.A. (Bank of America) on August 16, 2011. Under the ASR agreement, the Company agreed to repurchase $100 million of its common stock from Bank of America. During the quarter ended September 30, 2011, Bank of America delivered 4.3 million shares to the Company, at which point the Company's shares outstanding were reduced and accounted for as a reduction to retained earnings. The number of shares delivered was the minimum amount of shares Bank of America is contractually obligated to provide under the ASR agreement.

        The number of shares that ultimately were repurchased by the Company under the ASR agreement was based upon the volume-weighted average share price of the Company's common stock during the term of the ASR agreement, less an agreed discount, subject to collar provisions which established a maximum and minimum price and other customary conditions under the ASR agreement. The ASR agreement was settled in full on March 7, 2012 and the total number of shares repurchased was 4.8 million at an average price of $20.97.

• Rule 10b5-1 Repurchase Plan and Open Market Purchases

        In connection with the Repurchase Program, the Company entered into two Rule 10b5-1 repurchase plans. The timing, nature and amount of purchases depended on a variety of factors, including market conditions and the volume limit defined by Rule 10b-18.

        As of June 30, 2012, the Company had repurchased approximately 4.4 million shares under both the Rule 10b5-1 plans and open market purchases, at an average price of $22.59, for a total cost of approximately $100.0 million; thereby completing its initial authorization under the Repurchase Program.

• $300 million share repurchase authorization

        In August 2012, the Company's Board of Directors authorized an additional $300 million to repurchase its common stock under the Repurchase Program. As of September 30, 2012, the Company repurchased under open market purchases and purchases made under a Rule 10b5-1 plan, 3.0 million shares at an average price of $20.71, for a total cost of $62.3 million, which included 0.5 million shares repurchased in transactions that were settled in fiscal 2013. As of September 30, 2012, $237.7 million of shares remained available for repurchase pursuant to this repurchase program. Repurchased shares are retired, but remain authorized for registration and issuance in the future.

Significant Accounting Policies (Policies)

Significant Accounting Policies

Fiscal Year

Fiscal Year—The Company reports results of operations based on 52 or 53-week periods ending on the Friday nearest September 30. For clarity of presentation, all periods are presented as if the year ended on September 30. Fiscal years 2012, 2011 and 2010 each contained 52 weeks and ended on September 28, September 30, and October 1, respectively

Use of Estimates

 Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant estimates affecting amounts reported in the consolidated financial statements relate to revenues under long-term contracts and self-insurance accruals. Actual results could differ from those estimates.

Principles of Consolidation and Presentation

Principles of Consolidation and Presentation—The consolidated financial statements include the accounts of all majority-owned subsidiaries and material joint ventures in which the Company is the primary beneficiary. All inter-company accounts have been eliminated in consolidation. Also see Note 8 regarding joint ventures.

Revenue Recognition

Revenue Recognition—The Company generally utilizes a cost-to-cost approach in applying the percentage-of-completion method of revenue recognition. Under this approach, revenue is earned in proportion to total costs incurred, divided by total costs expected to be incurred. Recognition of revenue and profit is dependent upon a number of factors including, the accuracy of a variety of estimates made at the balance sheet date, engineering progress, materials quantities, the achievement of milestones, penalty provisions, labor productivity and cost estimates made at the balance sheet date. Due to uncertainties inherent in the estimation process, actual completion costs may vary from estimates. If estimated total costs on contracts indicate a loss, the Company recognizes that estimated loss in the period the estimated loss first becomes known.

        In the course of providing its services, the Company routinely subcontracts for services and incurs other direct costs on behalf of its clients. These costs are passed through to clients and, in accordance with industry practice and GAAP, are included in the Company's revenue and cost of revenue. Because subcontractor services and other direct costs can change significantly from project to project and period to period, changes in revenue may not be indicative of business trends. These other direct costs for the years ended September 30, 2012, 2011 and 2010 were $3.0 billion, $2.9 billion and $2.3 billion, respectively.

Government Contract Matters

Government Contract Matters—The Company's federal government and certain state and local agency contracts are subject to, among other regulations, regulations issued under the Federal Acquisition Regulations (FAR). These regulations can limit the recovery of certain specified indirect costs on contracts and subjects the Company to ongoing multiple audits by government agencies such as the Defense Contract Audit Agency (DCAA). In addition, most of the Company's federal and state and local contracts are subject to termination at the discretion of the client.

        Audits by the DCAA and other agencies consist of reviews of the Company's overhead rates, operating systems and cost proposals to ensure that the Company accounted for such costs in accordance with the Cost Accounting Standards of the FAR (CAS). If the DCAA determines the Company has not accounted for such costs consistent with CAS, the DCAA may disallow these costs. There can be no assurance that audits by the DCAA or other governmental agencies will not result in material cost disallowances in the future. See also Note 20.

Cash and Cash Equivalents

Cash and Cash Equivalents—The Company's cash equivalents include highly liquid investments which have an initial maturity of three months or less.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts—The Company records its accounts receivable net of an allowance for doubtful accounts. This allowance for doubtful accounts is estimated based on management's evaluation of the contracts involved and the financial condition of its clients. The factors the Company considers in its contract evaluations include, but are not limited to:

• •

  Client type—federal or state and local government or commercial client;

  •

  Historical contract performance;

  •

  Historical collection and delinquency trends;

• •

  Client credit worthiness; and

  •

  General economic conditions.

Derivative Financial Instruments

Derivative Financial Instruments—The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value.

        For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income in stockholders' equity and reclassified into income in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument, if any, is recognized in current income. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions.

        The net gain or loss on the effective portion of a derivative instrument that is designated as an economic hedge of the foreign currency translation exposure generated by the re-measurement of certain assets and liabilities denominated in a non-functional currency in a foreign operation is reported in the same manner as a foreign currency translation adjustment. Accordingly, any gains or losses related to these derivative instruments are recognized in current income.

        Derivatives that do not qualify as hedges are adjusted to fair value through current income.

Fair Value of Financial Instruments

Fair Value of Financial Instruments—The Company determines the fair values of its financial instruments, including short-term investments, debt instruments and derivative instruments, and pension and post-retirement plan assets based on inputs or assumptions that market participants would use in pricing an asset or a liability. The Company categorizes its instruments using a valuation hierarchy for disclosure of the inputs used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value. The classification of a financial asset or liability within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

        The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short maturities of these instruments. The carrying amount of the revolving credit facility approximates fair value because the interest rates are based upon variable reference rates. See also Notes 10 and 12.

        The Company's fair value measurement methods may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Although the Company believes its valuation methods are appropriate and consistent with those used by other market participants, the use of different methodologies or assumptions to determine fair value could result in a different fair value measurement at the reporting date.

Property and Equipment

Property and Equipment—Property and equipment are recorded at cost and are depreciated over their estimated useful lives using the straight-line method. Expenditures for maintenance and repairs are expensed as incurred. Typically, estimated useful lives range from three to ten years for equipment, furniture and fixtures. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the remaining terms of the underlying lease agreement.

Long-lived Assets

Long-lived Assets—Long-lived assets to be held and used are reviewed for impairment whenever events or circumstances indicate that the assets may be impaired. For assets to be held and used, impairment losses are recognized based upon the excess of the asset's carrying amount over the fair value of the asset. For long-lived assets to be disposed, impairment losses are recognized at the lower of the carrying amount or fair value less cost to sell.

Goodwill and Acquired Intangible Assets

Goodwill and Acquired Intangible Assets—Goodwill represents the excess amounts paid over the fair value of net assets acquired from an acquisition. In order to determine the amount of goodwill resulting from an acquisition, the Company performs an assessment to determine the value of the acquired company's tangible and identifiable intangible assets and liabilities. In its assessment, the Company determines whether identifiable intangible assets exist, which typically include backlog and customer relationships.

        The Company tests goodwill at least annually for each reporting unit. A reporting unit is defined as an operating segment or one level below an operating segment. The Company's impairment tests are performed at the operating segment level as they represent the Company's reporting units.

        The impairment test is a two-step process. During the first step, the Company estimates the fair value of the reporting unit using income and market approaches, and compares that amount to the carrying value of that reporting unit. In the event the fair value of the reporting unit is determined to be less than the carrying value, a second step is required. The second step requires the Company to perform a hypothetical purchase allocation for that reporting unit and to compare the resulting current implied fair value of the goodwill to the current carrying value of the goodwill for that reporting unit. In the event that the current implied fair value of the goodwill is less than the carrying value, an impairment charge is recognized. See also Note 4.

Pension Plans

Pension Plans—The Company has certain defined benefit pension plans. The Company calculates the market-related value of assets, which is used to determine the return-on-assets component of annual pension expense and the cumulative net unrecognized gain or loss subject to amortization. This calculation reflects the Company's anticipated long-term rate of return and amortization of the difference between the actual return (including capital, dividends, and interest) and the expected return over a five-year period. Cumulative net unrecognized gains or losses that exceed 10% of the greater of the projected benefit obligation or the market related value of plan assets are subject to amortization.

Insurance Reserves

Insurance Reserves—The Company maintains insurance for certain insurable business risks. Insurance coverage contains various retention and deductible amounts for which the Company accrues a liability based upon reported claims and an actuarially determined estimated liability for certain claims incurred but not reported. It is the Company's policy not to accrue for any potential legal expense to be incurred in defending the Company's position. The Company believes that its accruals for estimated liabilities associated with professional and other liabilities are sufficient and any excess liability beyond the accrual is not expected to have a material adverse effect on the Company's results of operations or financial position.

Foreign Currency Translation

Foreign Currency Translation—The Company's functional currency is the U.S. dollar. Results of operations for foreign entities are translated to U.S. dollars using the average exchange rates during the period. Assets and liabilities for foreign entities are translated using the exchange rates in effect as of the date of the balance sheet. Resulting translation adjustments are recorded as a foreign currency translation adjustment into other accumulated comprehensive income/(loss) in stockholders' equity.

        The Company uses foreign currency forward contracts from time to time to mitigate foreign currency risk. The Company limits exposure to foreign currency fluctuations in most of its contracts through provisions that require client payments in currencies corresponding to the currency in which costs are incurred. As a result of this natural hedge, the Company generally does not need to hedge foreign currency cash flows for contract work performed. The functional currency of all significant foreign operations is the respective local currency.

Income Taxes

Income Taxes—The Company files a consolidated federal income tax return and combined / consolidated state tax returns and separate company state tax returns. The Company accounts for certain income and expense items differently for financial reporting and income tax purposes. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the differences are expected to reverse. In determining the need for a valuation allowance, management reviews both positive and negative evidence, including current and historical results of operations, future income projections, and potential tax planning strategies. Based upon management's assessment of all available evidence, the Company has concluded that it is more likely than not that the deferred tax assets, net of valuation allowance, will be realized.

New Accounting Pronouncements and Changes in Accounting

New Accounting Pronouncements and Changes in Accounting

2. New Accounting Pronouncements and Changes in Accounting

        In January 2010, the Financial Accounting Standards Board (FASB) issued guidance to amend the disclosure requirements related to fair value measurements. The Company adopted this guidance for the quarter ended March 31, 2010, except for the portion of the guidance that requires the disclosure of activities on purchases, sales, issuance, and settlements of the assets and liabilities measured using significant unobservable inputs (Level 3 fair value measurements). The Level 3 fair value measurement guidance was adopted by the Company in its fiscal year beginning October 1, 2011. Since the Company carried no material Level 3 assets or liabilities during the period, the adoption of the separate disclosures related to Level 3 measurements did not have a material impact on its consolidated financial statements. Additionally, the FASB issued a new accounting standard on fair value measurements that changes certain fair value measurement principles, clarifies the requirement for measuring fair value and expands disclosure requirements, particularly for Level 3 fair value measurements. This guidance was effective for the Company in its second quarter ending March 31, 2012 and did not have a material impact on its consolidated financial statements.

        In June 2011, the FASB issued guidance on the presentation of comprehensive income. The new standard will require companies to present items of net income, items of other comprehensive income and total comprehensive income in one continuous statement or two separate consecutive statements, and companies will no longer be allowed to present items of other comprehensive income in the statement of stockholders' equity. This guidance is effective for the Company in its fiscal year beginning October 1, 2012 and, although it will change the financial statement presentation, it is not expected to have a material impact on its financial condition or results of operations.

        In September 2011, the FASB issued guidance intended to simplify goodwill impairment testing. Entities are allowed to 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 as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. This guidance is effective for goodwill impairment tests performed in interim and annual periods for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company does not expect this guidance will have a material impact on its consolidated financial statements.

        As of September 30, 2012, the Company has available unused state net operating loss (NOL) carry forwards of $257.3 million and foreign NOL carry forwards of $201.9 million which expire at various dates through 2031. In addition, as of September 30, 2012, the Company has available unused federal research and development credits of $12.7 million, which expire at various dates through 2031, unused state research and development credits of $11.5 million and California Enterprise Zone Tax Credits of $2.0 million which can be carried forward indefinitely.

        As of September 30, 2012 and 2011, gross deferred tax assets were $376.4 million and $351.3 million, respectively. The Company has recorded a valuation allowance of approximately $19.2 million and $17.8 million at September 30, 2012 and 2011, respectively, related to state and foreign net operating loss carry forwards and credits. The Company has performed an assessment of positive and negative evidence regarding the realization of the net deferred tax asset in accordance with ASC 740-10, "Accounting for Income Taxes." This assessment included the evaluation of scheduled reversals of deferred tax liabilities, the availability of carry forwards and estimates of projected future taxable income. Although realization is not assured, based on the Company's assessment, the Company has concluded that it is more likely than not that the remaining asset of $357.2 million will be realized and, as such, no additional valuation allowance has been provided.

        As of September 30, 2012 and September 30, 2011, the Company has remaining tax-deductible goodwill of $306.6 million and $343.2 million, respectively, resulting from acquisitions. The amortization of this goodwill is deductible over various periods ranging up to 15 years.

        The Company does not provide for U.S. taxes or foreign withholding taxes on undistributed earnings from non-U.S. subsidiaries because such earnings are intended to be reinvested indefinitely. The undistributed earnings are approximately $797.4 million. If undistributed pre-tax earnings were distributed, foreign tax credits could become available under current law to reduce the resulting U.S. income tax liability.

        As of September 30, 2012, the Company had a liability for unrecognized tax benefits, including potential interest and penalties, net of related tax benefit, totaling $56.3 million. The gross unrecognized tax benefits as of September 30, 2012 and 2011 were $55.8 million and $58.1 million, respectively, excluding interest, penalties, and related tax benefit. Of the $55.8 million, approximately $50.8 million, including related tax benefits, would be included in the effective tax rate if recognized in the fiscal year ended September 30, 2012. The adoption of ASC 805, "Accounting for Business Combinations," at the beginning of the fiscal year ended September 30, 2010 changed the treatment of the reversal of unrecognized tax benefits related to acquired companies which prior to adoption of ASC 805 would have impacted goodwill, but after the adoption of ASC 805, results in the recognition of income tax benefit. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows:

	Fiscal Year Ended
	September 30, 2012			September 30, 2011
	(in millions)
Balance at the beginning of the year	$	58.1		$	70.5
Gross increase in prior years' tax positions		3.7			5.3
Gross decrease in prior years' tax positions		(4.4	)		(13.7	)
(Decrease) due to settlement with tax authorities		(5.2	)		(2.9	)
Gross increase in current period's tax positions		4.9			4.9
Lapse of statute of limitations		(1.3	)		(6.0	)
Balance at the end of the year	$	55.8		$	58.1

        The Company classifies interest and penalties related to uncertain tax positions within the income tax expense line in the accompanying consolidated statements of operations. At September 30, 2012, the accrued interest and penalties were $9.6 million and $0.1 million, respectively, excluding any related income tax benefits. As of September 30, 2011, the accrued interest and penalties were $10.5 million and $0.1 million, respectively, excluding any related income tax benefits.

        The Company files income tax returns in numerous tax jurisdictions, including the U.S., and numerous U.S. states and non-U.S. jurisdictions around the world. The statute of limitations varies by jurisdiction in which the Company operates. Because of the number of jurisdictions in which the Company files tax returns, in any given year the statute of limitations in certain jurisdictions may expire without examination within the 12-month period from the balance sheet date. With few exceptions, the Company is no longer subject to U.S. (including federal, state and local) or non-U.S. income tax examinations by tax authorities for years before fiscal year 2006.

Significant Accounting Policies

1. Significant Accounting Policies

        Organization—AECOM Technology Corporation and its consolidated subsidiaries (the Company) provide professional technical and management support services for commercial and government clients around the world. These services encompass a variety of technical disciplines, including consulting, planning, architectural and engineering design, and program and construction management for a broad range of projects. These services are applied to a number of areas and industries, including transportation infrastructure; research, testing and defense facilities; water, wastewater and other environmental programs; land development; security and communication systems; institutional, mining, industrial and commercial and energy-related facilities. The Company also provides operations and maintenance services to governmental agencies throughout the U.S. and abroad.

        Fiscal Year—The Company reports results of operations based on 52 or 53-week periods ending on the Friday nearest September 30. For clarity of presentation, all periods are presented as if the year ended on September 30. Fiscal years 2012, 2011 and 2010 each contained 52 weeks and ended on September 28, September 30, and October 1, respectively.

        Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant estimates affecting amounts reported in the consolidated financial statements relate to revenues under long-term contracts and self-insurance accruals. Actual results could differ from those estimates.

        Principles of Consolidation and Presentation—The consolidated financial statements include the accounts of all majority-owned subsidiaries and material joint ventures in which the Company is the primary beneficiary. All inter-company accounts have been eliminated in consolidation. Also see Note 8 regarding joint ventures.

        Revenue Recognition—The Company generally utilizes a cost-to-cost approach in applying the percentage-of-completion method of revenue recognition. Under this approach, revenue is earned in proportion to total costs incurred, divided by total costs expected to be incurred. Recognition of revenue and profit is dependent upon a number of factors including, the accuracy of a variety of estimates made at the balance sheet date, engineering progress, materials quantities, the achievement of milestones, penalty provisions, labor productivity and cost estimates made at the balance sheet date. Due to uncertainties inherent in the estimation process, actual completion costs may vary from estimates. If estimated total costs on contracts indicate a loss, the Company recognizes that estimated loss in the period the estimated loss first becomes known.

        In the course of providing its services, the Company routinely subcontracts for services and incurs other direct costs on behalf of its clients. These costs are passed through to clients and, in accordance with industry practice and GAAP, are included in the Company's revenue and cost of revenue. Because subcontractor services and other direct costs can change significantly from project to project and period to period, changes in revenue may not be indicative of business trends. These other direct costs for the years ended September 30, 2012, 2011 and 2010 were $3.0 billion, $2.9 billion and $2.3 billion, respectively.

        Cost-Plus Contracts.    The Company enters into two major types of cost-plus contracts:

        Cost-Plus Fixed Fee.    Under cost-plus fixed fee contracts, the Company charges clients for its costs, including both direct and indirect costs, plus a fixed negotiated fee. The total estimated cost plus the fixed negotiated fee represents the total contract value. The Company recognizes revenue based on the actual labor and other direct costs incurred, plus the portion of the fixed fee it has earned to date.

        Cost-Plus Fixed Rate.    Under the Company's cost-plus fixed rate contracts, the Company charges clients for its direct and indirect costs based upon a negotiated rate. The Company recognizes revenue based on the actual total costs it has expended and the applicable fixed rate.

        Certain cost-plus contracts provide for award fees or a penalty based on performance criteria in lieu of a fixed fee or fixed rate. Other contracts include a base fee component plus a performance-based award fee. In addition, the Company may share award fees with subcontractors. The Company records accruals for fee-sharing as fees are earned. The Company generally recognizes revenue to the extent of costs actually incurred plus a proportionate amount of the fee expected to be earned. The Company takes the award fee or penalty on contracts into consideration when estimating revenue and profit rates, and it records revenue related to the award fees when there is sufficient information to assess anticipated contract performance. On contracts that represent higher than normal risk or technical difficulty, the Company may defer all award fees until an award fee letter is received. Once an award fee letter is received, the estimated or accrued fees are adjusted to the actual award amount.

        Certain cost-plus contracts provide for incentive fees based on performance against contractual milestones. The amount of the incentive fees varies, depending on whether the Company achieves above, at, or below target results. The Company originally recognizes revenue on these contracts based upon expected results. These estimates are revised when necessary based upon additional information that becomes available as the contract progresses.

• Time-and-Materials Contracts.

        Time-and-Materials.    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 its actual out-of-pocket costs of materials and other direct incidental expenditures that it incurs in connection with its performance under the contract. 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. Many of the Company's time-and-materials contracts are subject to maximum contract values and, accordingly, revenue relating to these contracts is recognized as if these contracts were a fixed-price contract.

• Fixed-Price Contracts.

        Firm Fixed-Price.    Fixed-price contracting is the predominant contracting method outside of the United States. There are typically two types of fixed-price contracts. The first and more common type, lump-sum, involves performing all of the work under the contract for a specified lump-sum fee. Lump-sum contracts are typically subject to price adjustments if the scope of the project changes or unforeseen conditions arise. The second type, fixed-unit price, involves performing an estimated number of units of work at an agreed price per unit, with the total payment under the contract determined by the actual number of units delivered. The Company recognizes revenue on firm fixed-price contracts using the percentage-of-completion method described above. Prior to completion, recognized profit margins on any firm fixed-price contract depend on the accuracy of the Company's estimates and will increase to the extent that its actual costs are below the estimated amounts. Conversely, if the Company's costs exceed these estimates, its profit margins will decrease and the Company may realize a loss on a project. The Company recognizes anticipated losses on contracts in the period in which they become evident.

• Service-Related Contracts.

        Service-Related.    Service-related contracts, including operations and maintenance services and a variety of technical assistance services, are accounted for over the period of performance, in proportion to the costs of performance.

        Contract Claims—Claims are amounts in excess of the agreed contract price (or amounts not included in the original contract price) that the Company seeks to collect from customers or others for delays, errors in specifications and designs, contract terminations, change orders in dispute or unapproved as to both scope and price or other causes of unanticipated additional costs. The Company records contract revenue related to claims only if it is probable that the claim will result in additional contract revenue and if the amount can be reliably estimated. In such cases, the Company records revenue only to the extent that contract costs relating to the claim have been incurred. As of September 30, 2012 and 2011, the Company had no significant net receivables related to contract claims.

        Government Contract Matters—The Company's federal government and certain state and local agency contracts are subject to, among other regulations, regulations issued under the Federal Acquisition Regulations (FAR). These regulations can limit the recovery of certain specified indirect costs on contracts and subjects the Company to ongoing multiple audits by government agencies such as the Defense Contract Audit Agency (DCAA). In addition, most of the Company's federal and state and local contracts are subject to termination at the discretion of the client.

        Audits by the DCAA and other agencies consist of reviews of the Company's overhead rates, operating systems and cost proposals to ensure that the Company accounted for such costs in accordance with the Cost Accounting Standards of the FAR (CAS). If the DCAA determines the Company has not accounted for such costs consistent with CAS, the DCAA may disallow these costs. There can be no assurance that audits by the DCAA or other governmental agencies will not result in material cost disallowances in the future. See also Note 20.

        Cash and Cash Equivalents—The Company's cash equivalents include highly liquid investments which have an initial maturity of three months or less.

        Allowance for Doubtful Accounts—The Company records its accounts receivable net of an allowance for doubtful accounts. This allowance for doubtful accounts is estimated based on management's evaluation of the contracts involved and the financial condition of its clients. The factors the Company considers in its contract evaluations include, but are not limited to:

• •

  Client type—federal or state and local government or commercial client;

  •

  Historical contract performance;

  •

  Historical collection and delinquency trends;

• •

  Client credit worthiness; and

  •

  General economic conditions.

        Derivative Financial Instruments—The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value.

        For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income in stockholders' equity and reclassified into income in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument, if any, is recognized in current income. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions.

        The net gain or loss on the effective portion of a derivative instrument that is designated as an economic hedge of the foreign currency translation exposure generated by the re-measurement of certain assets and liabilities denominated in a non-functional currency in a foreign operation is reported in the same manner as a foreign currency translation adjustment. Accordingly, any gains or losses related to these derivative instruments are recognized in current income.

        Derivatives that do not qualify as hedges are adjusted to fair value through current income.

        Fair Value of Financial Instruments—The Company determines the fair values of its financial instruments, including short-term investments, debt instruments and derivative instruments, and pension and post-retirement plan assets based on inputs or assumptions that market participants would use in pricing an asset or a liability. The Company categorizes its instruments using a valuation hierarchy for disclosure of the inputs used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value. The classification of a financial asset or liability within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

        The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short maturities of these instruments. The carrying amount of the revolving credit facility approximates fair value because the interest rates are based upon variable reference rates. See also Notes 10 and 12.

        The Company's fair value measurement methods may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Although the Company believes its valuation methods are appropriate and consistent with those used by other market participants, the use of different methodologies or assumptions to determine fair value could result in a different fair value measurement at the reporting date.

        Property and Equipment—Property and equipment are recorded at cost and are depreciated over their estimated useful lives using the straight-line method. Expenditures for maintenance and repairs are expensed as incurred. Typically, estimated useful lives range from three to ten years for equipment, furniture and fixtures. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the remaining terms of the underlying lease agreement.

        Long-lived Assets—Long-lived assets to be held and used are reviewed for impairment whenever events or circumstances indicate that the assets may be impaired. For assets to be held and used, impairment losses are recognized based upon the excess of the asset's carrying amount over the fair value of the asset. For long-lived assets to be disposed, impairment losses are recognized at the lower of the carrying amount or fair value less cost to sell.

        Goodwill and Acquired Intangible Assets—Goodwill represents the excess amounts paid over the fair value of net assets acquired from an acquisition. In order to determine the amount of goodwill resulting from an acquisition, the Company performs an assessment to determine the value of the acquired company's tangible and identifiable intangible assets and liabilities. In its assessment, the Company determines whether identifiable intangible assets exist, which typically include backlog and customer relationships.

        The Company tests goodwill at least annually for each reporting unit. A reporting unit is defined as an operating segment or one level below an operating segment. The Company's impairment tests are performed at the operating segment level as they represent the Company's reporting units.

        The impairment test is a two-step process. During the first step, the Company estimates the fair value of the reporting unit using income and market approaches, and compares that amount to the carrying value of that reporting unit. In the event the fair value of the reporting unit is determined to be less than the carrying value, a second step is required. The second step requires the Company to perform a hypothetical purchase allocation for that reporting unit and to compare the resulting current implied fair value of the goodwill to the current carrying value of the goodwill for that reporting unit. In the event that the current implied fair value of the goodwill is less than the carrying value, an impairment charge is recognized. See also Note 4.

        Pension Plans—The Company has certain defined benefit pension plans. The Company calculates the market-related value of assets, which is used to determine the return-on-assets component of annual pension expense and the cumulative net unrecognized gain or loss subject to amortization. This calculation reflects the Company's anticipated long-term rate of return and amortization of the difference between the actual return (including capital, dividends, and interest) and the expected return over a five-year period. Cumulative net unrecognized gains or losses that exceed 10% of the greater of the projected benefit obligation or the market related value of plan assets are subject to amortization.

        Insurance Reserves—The Company maintains insurance for certain insurable business risks. Insurance coverage contains various retention and deductible amounts for which the Company accrues a liability based upon reported claims and an actuarially determined estimated liability for certain claims incurred but not reported. It is the Company's policy not to accrue for any potential legal expense to be incurred in defending the Company's position. The Company believes that its accruals for estimated liabilities associated with professional and other liabilities are sufficient and any excess liability beyond the accrual is not expected to have a material adverse effect on the Company's results of operations or financial position.

        Foreign Currency Translation—The Company's functional currency is the U.S. dollar. Results of operations for foreign entities are translated to U.S. dollars using the average exchange rates during the period. Assets and liabilities for foreign entities are translated using the exchange rates in effect as of the date of the balance sheet. Resulting translation adjustments are recorded as a foreign currency translation adjustment into other accumulated comprehensive income/(loss) in stockholders' equity.

        The Company uses foreign currency forward contracts from time to time to mitigate foreign currency risk. The Company limits exposure to foreign currency fluctuations in most of its contracts through provisions that require client payments in currencies corresponding to the currency in which costs are incurred. As a result of this natural hedge, the Company generally does not need to hedge foreign currency cash flows for contract work performed. The functional currency of all significant foreign operations is the respective local currency.

        Income Taxes—The Company files a consolidated federal income tax return and combined / consolidated state tax returns and separate company state tax returns. The Company accounts for certain income and expense items differently for financial reporting and income tax purposes. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the differences are expected to reverse. In determining the need for a valuation allowance, management reviews both positive and negative evidence, including current and historical results of operations, future income projections, and potential tax planning strategies. Based upon management's assessment of all available evidence, the Company has concluded that it is more likely than not that the deferred tax assets, net of valuation allowance, will be realized.

Derivative Financial Instruments

11. 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 operations as cost of revenue, interest expense, net, 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, net when the interest expense on the variable rate debt is recognized, or to cost of sales 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 sales.

        At September 30, 2012, the effective portion of our interest rate swap agreements designated as cash flow hedges before tax effect was $6.2 million, of which $2.9 million is expected to be reclassified from accumulated other comprehensive loss to interest expense, net within the next 12 months. At September 30, 2012, the effective portion of the Company's foreign currency options designated as cash flow hedges before tax effect, were immaterial.

        As of September 30, 2012, the notional principal, fixed rates and related expiration dates of the Company's outstanding interest rate swap agreements are as follows:

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

        As of September 30, 2011, the notional principal, fixed rates and related expiration dates of the Company's outstanding interest rate swap agreements are as follows:

Notional Amount (in millions)		Fixed Rate			Expiration Date
$	250.0		0.95	%	September 2015

        The notional principal of foreign currency options to purchase British Pounds (GBP) with Brazilian Reais (BRL) was BRL 16.4 million (or approximately $8.1 million) at September 30, 2012. These foreign exchange contracts have maturities of 24 months or less. The Company had no foreign currency options outstanding at September 30, 2011.

• 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 sales for those instruments related to the provision of our 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 $60.1 million at September 30, 2012. The notional principal of foreign currency forward contracts to sell U.S. dollars for foreign currencies was $110.2 million at September 30, 2012. The notional principal of foreign currency forward contracts to purchase GBP with BRL was BRL 9.7 million (or approximately $4.9 million) at September 30, 2012. The notional principal of foreign currency forward contracts to sell U.S. dollars for foreign currencies was $57.1 million at September 30, 2011.

• 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 sales. 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 sales. The notional principal of option contracts to sell U.S. dollars for foreign currencies was $17.3 million at September 30, 2012 and no such option contracts were outstanding at September 30, 2011.

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

Fair Value Measurements

Fair Value Measurements

12. 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 year ended September 30, 2012, the Company recognized an impairment of goodwill within both its PTS and MSS reportable segments. For further information regarding the impairment of goodwill refer to Note 4 herein. During the year ended September 30, 2011, the Company did not record any fair market 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 may be used to measure fair value, as discussed in Note 1. There were no significant transfers between any of the levels of the fair value hierarchy during the years ended September 30, 2012 and 2011. The Company classifies its derivative financial instruments within Level 2 as the valuation inputs are based on quoted prices and market observable data of similar instruments.

        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:

	September 30, 2012		Quoted Prices in Active Markets for Similar Assets (Level 2)

Substantially all unbilled receivables as of September 30, 2012 and 2011 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, other contractual conditions or upon the completion of the 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 September 30, 2012 and 2011.

        The Company sold trade receivables to a financial institution, of which $31.2 million was outstanding as of September 30, 2012. The Company does not retain financial or legal interest in these receivables.

Stock Plans

17. Stock Plans

        Defined Contribution Plans—Substantially all permanent employees are eligible to participate in defined contribution plans provided by the Company. Under these plans, participants may make contributions into a variety of funds, including a fund that is fully invested in Company stock. Employees are not required to allocate any funds to Company stock, which allows employees to limit their exposure to market changes in the Company's stock price. Employees may generally reallocate their account balances on a daily basis. The only limit on the frequency of reallocations applies to changes involving Company stock investments by employees classified as insiders or restricted personnel under the Company's insider trading policy.

        Deferred Compensation Plan—In the past, the Company sponsored the Deferred Compensation Plan (DCP), a stock purchase plan that provided an opportunity for eligible employees and non-employee directors to continue to invest in the Company when the Company's qualified plans were no longer available to them due to limitations contained in the U.S. Internal Revenue Code. Under the DCP, participants were permitted to defer compensation, on a pre-tax basis, for investment in common stock units. The Company funded a rabbi trust for certain diversified DCP balances in connection with the initial public offering in May 2007. The Company elected to terminate this plan effective in December 2009. As a result of the termination, 6.3 million outstanding restricted stock units and the Company's deferred compensation liability of $88.8 million as of September 30, 2010 were settled in December 2010. Investments in the rabbi trust totaled $67.2 million as of September 2010, which were substantially used to settle the liability.

        Compensation expense relating to employer contributions under defined contribution plans, including the DCP, for fiscal years ended September 30, 2012, 2011 and 2010 was $15.9 million, $17.2 million and $15.8 million, respectively. Issuances and repurchases of AECOM common stock related to employee participants' contributions to and withdrawals from these defined contribution plans are included as issuances and repurchases of stock in the accompanying Consolidated Statements of Stockholders' Equity and of Cash Flows.

        Stock Incentive Plans—Under the 2006 Stock Incentive Plan, the Company has 15.7 million securities remaining available for future issuance under stock options or restricted stock awards as of September 30, 2012. Stock options may be granted to employees and non-employee directors with an exercise price not less than the fair market value of the stock on the date of grant. Unexercised options expire seven years after date of grant. During the years ended September 30, 2012, 2011 and 2010, compensation expense recognized relating to employee stock options as a result of the fair value method was $2.4 million, $4.6 million and $4.1 million, respectively. Unrecognized compensation expense relating to employee stock options outstanding as of September 30, 2012 was $1.3 million to be recognized on a straight-line basis over the awards' respective vesting periods which are generally three years.

        The fair value of the Company's stock options granted to employees were determined using the following weighted average assumptions:

	Fiscal Year Ended
	September 30, 2011			September 30, 2010
Dividend yield		0.0	%		0.0	%
Expected volatility		38.6	%		39.9	%
Risk-free interest rate		1.5	%		1.6	%
Term (in years)		4.5			4.5

        The weighted average grant-date fair value of stock options granted during the years ended September 30, 2011 and 2010 was $9.43 and $8.77, respectively.

        During the three years in the period ended September 30, 2012, option activity was as follows:

	Number of Options (in millions)			Weighted Average Exercise Price

        The remaining contractual life of options outstanding at September 30, 2012, range from 0 to 6 years and have a weighted average remaining contractual life of 2.94 years. The aggregate intrinsic value of stock options exercised during the years ended September 30, 2012, 2011 and 2010 was $3.9 million, $7.8 million and $17.9 million, respectively.

        The Company grants stock units to employees under the Performance Earnings Program (PEP), whereby units are earned and issued dependent upon meeting established cumulative performance objectives over a three-year period. The Company recognized compensation expense relating to the PEP of $3.2 million, $7.3 million and $22.3 million during the years ended September 30, 2012, 2011 and 2010, respectively. Additionally, the Company issues restricted stock units, which are earned based on service conditions, resulting in compensation expenses of $20.9 million, $13.1 million and $7.5 million during the years ended September 30, 2012, 2011 and 2010, respectively. Unrecognized compensation expense related to PEP units and restricted stock units outstanding as of September 30, 2012 was $7.1 million and $30.6 million, respectively, to be recognized on a straight-line basis over the awards' respective vesting periods which are generally three years.

        Cash flow 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 $1.3 million, $61.2 million and $17.3 million for the years ended September 30, 2012, 2011 and 2010, respectively, have been classified as financing cash inflows in the Condensed Consolidated Statements of Cash Flows.

Concentration of Credit Risk

Concentration of Credit Risk

13. Concentration of Credit Risk

        Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of temporary cash investments and trade receivables. The Company's cash balances and short-term investments are maintained in accounts held by major banks and financial institutions located primarily in the U.S., Canada, Europe, Australia, Middle East and Hong Kong. If the Company extends a significant portion of its credit to clients in a specific geographic area or industry, the Company may experience disproportionately high levels of default if those clients are adversely affected by factors particular to their geographic area or industry. Concentrations of credit risk with respect to trade receivables are limited due to the large number of customers comprising the Company's customer base, including, in large part, governments, government agencies and quasi-government organizations, and their dispersion across many different industries and geographies. See Note 21 regarding the Company's foreign revenues. In order to mitigate credit risk, the Company continually reviews the credit worthiness of its major private clients.

9. Pension Plans

        In the U.S., the Company sponsors a Defined Benefit Pension Plan (the Pension Plan) which covers substantially all permanent employees hired as of March 1, 1998, subject to eligibility and vesting requirements, and required contributions from participating employees through March 31, 1998. Benefits under this plan generally are based on the employee's years of creditable service and compensation. Effective April 1, 2004, the Company set a maximum on the amount of compensation used to determine pension benefits based on the highest calendar year of compensation earned in the 10 completed calendar years from 1994 through 2003, or the relevant IRS annual compensation limit, $200,000, whichever is lower. Outside the U.S., the Company sponsors various pension plans, which are appropriate to the country in which the Company operates, some of which are government mandated.

        During the quarter ended December 31, 2009, the Company adopted an amendment to freeze pension plan benefit accruals for certain U.S. employee plans resulting in a curtailment gain of $1.9 million. During the quarter ended March 31, 2011, the Company adopted an amendment to freeze pension plan benefit accruals for certain U.K. and Ireland employee plans resulting in a curtailment gain of $4.2 million.

        The following tables provide reconciliations of the changes in the U.S. and international plans' benefit obligations, reconciliations of the changes in the fair value of assets for the years ended September 30, and reconciliations of the funded status as of September 30 of each year.

        Funding requirements for each plan are determined based on the local laws of the country where such plan resides. In certain countries, the funding requirements are mandatory while in other countries, they are discretionary. The Company currently expects to contribute $17.3 million to the international plans in fiscal 2013 The Company does not have a required minimum contribution for the U.S. plans; however, the Company may make additional discretionary contributions. The Company currently expects to contribute $8.9 million to U.S. plans in fiscal 2013.

        Pension costs are determined using the assumptions as of the beginning of the plan year, October 1. The funded status is determined using the assumptions as of the end of the plan year.

        The following table summarizes the Company's target allocation for 2012 and pension plan asset allocation, both U.S. and international, as of September 30, 2012 and 2011:

        The Company's policy is to minimize the risk of large losses through diversification in a portfolio of stocks, bonds, and cash equivalents, as appropriate, which may reflect varying rates of return. The percentage of assets allocated to cash is to assure liquidity to meet benefit disbursements and general operating expenses.

        To develop the expected long-term rate of return on assets assumption, the Company considered the historical returns and the future expectations for returns for each asset class, as well as the target asset allocation of the pension portfolio and the diversification of the portfolio. This resulted in the selection of a 7.5% and 5.7% weighted-average long-term rate of return on assets assumption for the fiscal year ended September 30, 2012 for U.S. and non-U.S. plans, respectively.

        Cash equivalents are mostly comprised of short-term money-market instruments and are valued at cost, which approximates fair value.

        For equity investment funds not traded on an active exchange, or if the closing price is not available, the trustee obtains indicative quotes from a pricing vendor, broker, or investment manager. These funds are categorized as Level 2 if the custodian obtains corroborated quotes from a pricing vendor or categorized as Level 3 if the custodian obtains uncorroborated quotes from a broker or investment manager.

        Fixed income investment funds categorized as Level 2 are valued by the trustee using pricing models that use verifiable observable market data (e.g., interest rates and yield curves observable at commonly quoted intervals), bids provided by brokers or dealers, or quoted prices of securities with similar characteristics.

        Hedge funds categorized as Level 3 are valued based on valuation models that include significant unobservable inputs and cannot be corroborated using verifiable observable market data. Hedge funds are valued by independent administrators. Depending on the nature of the assets, the general partners or independent administrators use both the income and market approaches in their models. The market approach consists of analyzing market transactions for comparable assets while the income approach uses earnings or the net present value of estimated future cash flows adjusted for liquidity and other risk factors. As of September 30, 2012, there were no material changes to the valuation techniques.

Joint Ventures and Variable Interest Entities

Joint Ventures and Variable Interest Entities

8. 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 a representative 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's economics.

        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 entities, 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 result 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 which provide a party the power to direct the activities that most significantly impact the joint ventures' 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 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.

        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 20.

        Summary of unaudited financial information of the consolidated joint ventures is as follows:

• Unsecured Term Credit Agreements

        In September 2011, the Company entered into an Amended and Restated Credit Agreement (the "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 in term loans on the closing date and may borrow up to an additional $100 million in term loans upon request by the Company subject to certain conditions, including Company and lender approval. The Company used approximately $600 million of the proceeds from the loans to repay indebtedness under its prior term loan facility, approximately $147 million of the proceeds to pay down indebtedness under its revolving credit facility and a portion of the proceeds to pay fees and expenses related to the Term Credit Agreement. 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 0.375% to 1.50% and the applicable margin for Eurodollar Rate loans is a range of 1.375% to 2.50%, both based on the debt-to-earnings leverage ratio of the Company at the end of each fiscal quarter. The initial interest rate of the loans borrowed on September 30, 2011 was the 3 month Eurodollar rate plus 1.75%, or a total of 2.12%. For the years ended September 30, 2012 and 2011, the average interest rate of the Company's term loan facility was 2.19% and 3.01%, respectively. Payments of the initial principal amount outstanding under the Term Credit Agreement are required on a quarterly basis beginning on December 31, 2012, while interest payments are made on a quarterly basis beginning December 31, 2011. Any remaining principal of the loans under the Term Credit Agreement is due no later than July 20, 2016. Accrued interest is payable in arrears on a quarterly basis for Base Rate loans, and at the end of the applicable interest period (but at least every three months) for Eurodollar Rate loans. The Company may optionally prepay the loans at any time, without penalty.

• 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 was $81.8 million and $78.6 million at September 30, 2012 and 2011, respectively, which have an effective interest rate of 5.62%. The fair value of the Company's unsecured senior notes was approximately $277.8 million at September 30, 2012 and $259.2 million at September 30, 2011. 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.

• Unsecured Revolving Credit Facility

        In July 2011, the Company entered into a Third Amended and Restated Credit Agreement (the "Revolving Credit Agreement") with Bank of America, N.A., as an administrative agent and a lender and the other lenders party thereto, which amended and restated its unsecured revolving credit facility and increased its available borrowing capacity to $1.05 billion in order to support its working capital and acquisition needs. The Revolving Credit Agreement has an expiration date of July 20, 2016 and prior to this expiration date, principal amounts outstanding under the Revolving Credit Agreement may be repaid and reborrowed at the option of the Company without prepayment or penalty, subject to certain conditions. The Company may also, at its option, request an increase in the commitments under the facility up to a total of $1.15 billion, subject to certain conditions, including Company and lender approval. 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 0.0% to 1.50% and the applicable margin for the Eurocurrency Rate loans is a range of 1.00% to 2.50%, 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 0.150% to 0.375% on any unused commitment. Accrued interest is payable in arrears on a quarterly basis for Base Rate loans, and at the end of the applicable interest period (but at least every three months) for Eurocurrency Loans. At September 30, 2012 and 2011, $24.0 million and $101.4 million, respectively, were outstanding under the revolving credit facility. At September 30, 2012 and 2011, outstanding standby letters of credit totaled $35.1 million and $32.1 million, respectively, under the revolving credit facility. As of September 30, 2012, the Company had $990.9 million available under its Revolving Credit Agreement.

• Covenants and Restrictions

        Under the Company's debt agreements relating to its unsecured revolving credit facility and unsecured term credit agreements, the Company is subject to a maximum consolidated leverage ratio at the end of any fiscal quarter. This ratio is calculated by dividing consolidated funded debt (including financial letters of credit) by consolidated earnings before interest, taxes, depreciation, and amortization (EBITDA). For 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 the Company's acquisitions). As of September 30, 2012, the consolidated leverage ratio was 2.15, which did not exceed the Company's most restrictive maximum consolidated leverage ratio 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 ended 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 September 30, 2012, this amount was $2.2 billion, which exceeds the calculated threshold of $1.5 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 September 30, 2012 and 2011, 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, refer to Note 11 herein for additional information regarding the Company's interest rate swap agreements, during the years ended September 30, 2012 and 2011 was 3.1% and 3.3%, respectively.

• Notes Secured by Real Properties

        Notes secured by real properties, payable to a bank, were assumed in connection with a business acquired during the year ended September 30, 2008. These notes payable bear interest at 6.04% per annum and mature in December 2028.

• Other Debt

        Other debt consists primarily of bank overdrafts and obligations under capital leases. In addition to the unsecured revolving credit facility discussed above, at September 30, 2012, the Company had $470.1 million of unsecured credit facilities primarily used to cover periodic overdrafts and standby letters of credit, of which $209.8 million was utilized for outstanding standby letters of credit.

Commitments and Contingencies

Commitments and Contingencies

20. 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 operations 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 September 30, 2012, the Company was contingently liable in the amount of approximately $244.9 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. 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 operations or cash flows.

• Combat Support Associates Joint Venture

        As of September 30, 2012, the Company has settled the previously disclosed Combat Support Associates Defense Contract Audit Agency (DCAA) Form 1 matter.

• Global Linguists Solutions Joint Venture

        On October 5, 2011 and February 8, 2012, the DCAA issued DCAA Forms 1 questioning costs incurred by Global Linguists Solutions (GLS), an equity method joint venture, of which McNeil Technologies, Inc., acquired by the Company in August 2010, is an owner. The questioned costs were incurred by GLS during fiscal 2009, a period prior to the acquisition. Specifically, the DCAA questioned direct labor, associated burdens, and fees billed to the U.S. Government for linguists that allegedly did not meet specific contract requirements. As a result of the issuance of the DCAA Forms 1, the U.S. Government has withheld approximately $19 million from payments on current year billings pending final resolution.

        GLS is performing a review of the issues raised in the Forms 1 in order to respond fully to the questioned costs. Based on a review, GLS believes that the costs met the applicable contract requirements.

        Additionally, on April 20, 2012, GLS received a subpoena from the Inspector General of the U.S. Department of Defense requesting documentation related to this contract with the United States Army. GLS plans to respond fully to the request. If the DCAA Forms 1 are not overruled and subsequent appeals are unsuccessful or there are unfavorable consequences from the Inspector General's investigation, these events could have a material adverse effect on the Company's results of operations.

• 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 a special purpose vehicle (SPV) that raised approximately $700 million Australian dollars through an initial public offering (IPO) of equity units in 2006 and another approximately $1.4 billion Australian dollars in long term bank loans. The SPV (and certain affiliated SPVs) went into insolvency administrations in February 2011.

        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. Separately, KordaMentha, the receivers for the SPVs, filed a lawsuit in the Federal Court of Australia on May 14, 2012 claiming damages that purportedly resulted from AECOM Australia's role in connection with the above described traffic forecast. WestLB, one of the lending banks to the SPVs, filed a lawsuit in the Federal Court of Australia on May 18, 2012. Centerbridge Credit Partners (and a number of related entities) and Midtown Acquisitions (and a number of related entities), both claiming to be assignees of certain other lending banks, previously filed their own proceedings in the Federal Court of Australia and then subsequently withdrew the lawsuits. None of the lawsuits specify the amount of damages sought and the damages sought by WestLB are duplicative of damages already included in the receivers' claim.

        AECOM Australia intends to vigorously defend the claims brought against it.

• Hawaii Project

        The U.S. Attorney's Office (USAO) informed us that the USAO and the U.S. Environmental Protection Agency are investigating potential criminal charges in connection with services our subsidiary provided to the operator of the Waimanalo Gulch Sanitary Landfill in Hawaii. The Company has cooperated fully with the investigation and, as of this date, no actions have been filed. The Company believes that the investigation will show that there has been no criminal wrongdoing on our part or any of our subsidiaries and, if any actions are brought, the Company intends to vigorously defend against such actions.

        The services performed by the subsidiary included the preparation of a pollution control plan, which the operator used to obtain permits necessary for the operation of the landfill. The USAO is investigating whether flooding at the landfill that resulted in the discharge of waste materials and storm water into the Pacific Ocean in December 2010 and January 2011 was due in part to reliance on information contained in the plan prepared by a subsidiary of the Company.

Business Acquisitions, Goodwill, and Intangible Assets

Business Acquisitions, Goodwill, and Intangible Assets

4. Business Acquisitions, Goodwill, and Intangible Assets

        The Company completed one, six, and six business acquisitions during the years ended September 30, 2012, 2011 and 2010, respectively. Business acquisitions completed during the years ended September 30, 2012, 2011 and 2010 did not meet the quantitative thresholds to require proforma disclosures of operating results, either individually or in the aggregate, based on the Company's consolidated assets, investments and net income.

        Business acquisitions during the year ended September 30, 2012 included an environmental engineering firm in Asia.

        Business acquisitions during the year ended September 30, 2011 included four separate global cost and project management consultancy firms that operated under the Davis Langdon name, including businesses in Europe and Middle East, Australia and New Zealand, Africa, and North America. Each of the four acquisitions were separately negotiated, executed by separate purchase agreements, with no one acquisition contingent upon the other, and the businesses, although operating as part of a Swiss Verein, under which they shared certain naming and marketing rights, were not under common control or management. Business acquisitions for the year ended September 30, 2011 also included RSW, Inc., an international engineering firm based in Montreal, Quebec, Canada and Spectral Services Consultants Pte. Ltd. (Spectral), a building services consultancy in India.

        Business acquisitions during the year ended September 30, 2010 included Tishman Construction Corporation (Tishman), a New York based provider of construction management services in the United States and the United Arab Emirates, and MT Holdings Corporation, the parent of McNeil Technologies, Inc. (McNeil), a government national security and intelligence services firm based in Virginia.

        The aggregate value of all consideration for acquisitions consummated during the years ended September 30, 2012, 2011 and 2010 were $15.4 million, $453.3 million and $768.0 million, respectively. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed, as of the acquisition dates, from acquisitions consummated during the fiscal years presented:

	Fiscal Year Ended
	September 30, 2012			September 30, 2011			September 30, 2010
	(in millions)
Cash acquired	$	1.9		$	19.3		$	143.3
Other current assets		7.8			149.2			212.5
Goodwill		10.5			405.2			618.1
Intangible assets		1.5			44.3			63.6
Other non-current assets		3.3			51.5			33.1
Current liabilities		(8.8	)		(140.5	)		(265.4	)
Non-current liabilities		(0.8	)		(75.7	)		(37.2	)
Net assets acquired	$	15.4		$	453.3		$	768.0

        Acquired intangible assets above includes the following:

	Fiscal Year Ended
	September 30, 2012		September 30, 2011		September 30, 2010
	(in millions)
Backlog	$	0.7	$	10.7	$	16.8
Customer relationships		0.8		30.2		42.6
Trademark / tradename		—		3.4		4.2
Total intangible assets	$	1.5	$	44.3	$	63.6

        Consideration for acquisitions above includes the following:

	Fiscal Year Ended
	September 30, 2012		September 30, 2011		September 30, 2010
	(in millions)
Cash paid	$	14.5	$	384.8	$	702.7
Equity issued		0.9		68.5		65.3
Total consideration	$	15.4	$	453.3	$	768.0

        All of the above acquisitions were accounted for under the acquisition method of accounting. As such, the purchase consideration of each acquired company was allocated to acquired tangible and intangible assets and liabilities based upon their fair values. The excess of the purchase consideration over the fair value of the net tangible and identifiable intangible assets acquired was recorded as goodwill. The results of operations of each company acquired have been included in the Company's financial statements from the date of acquisition.

        At the time of acquisition, the Company preliminarily estimates the amount of the identifiable intangible assets acquired based upon historical valuations of similar acquisitions and the facts and circumstances available at the time. 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.

        During the fourth quarter of the year ended September 30, 2012, the Company conducted its annual goodwill impairment test. The impairment evaluation process includes, among other things, making assumptions about variables such as revenue growth rates, profitability, discount rates, and industry market multiples, which are subject to a high degree of judgment. As a result of the first step of the impairment analysis, due to market conditions and business trends within the Europe, Middle East, and Africa (EMEA) and MSS reporting units, the Company determined that goodwill was impaired. The second step of the analysis is performed to measure the impairment as the excess of the goodwill carrying value over its implied fair value. This analysis resulted in an impairment of $336.0 million, or $317.2 million, net of tax.

        The changes in the carrying value of goodwill by reportable segment for the fiscal years ended September 30, 2012, 2011 and 2010 were as follows:

	Fiscal Year 2012
	September 30, 2011		Post- Acquisition Adjustments			Foreign Exchange Impact		Acquired		Goodwill Impairment			September 30, 2012
	(in millions)
Professional Technical Services	$	1,733.9	$	(1.2	)	$	20.4	$	10.5	$	(155.0	)	$	1,608.6

Total	$	2,086.3	$	(5.8	)	$	20.4	$	10.5	$	(336.0	)	$	1,775.4

	Fiscal Year 2011
	September 30, 2010		Post- Acquisition Adjustments			Foreign Exchange Impact			Acquired		September 30, 2011

Total	$	1,690.4	$	12.1		$	(21.4	)	$	405.2	$	2,086.3

        The gross amounts and accumulated amortization of the Company's acquired identifiable intangible assets with finite useful lives as of September 30, 2012 and 2011, included in intangible assets—net, in the accompanying consolidated balance sheets, were as follows:

	September 30, 2012							September 30, 2011
	Gross Amount		Accumulated Amortization			Intangible Assets, Net		Gross Amount		Accumulated Amortization			Intangible Assets, Net		Amortization Period (years)
	(in millions)
Backlog	$	91.1	$	(83.8	)	$	7.3	$	91.5	$	(79.8	)	$	11.7	1 - 5
Customer relationships		143.6		(54.1	)		89.5		143.2		(39.3	)		103.9	10
Trademark / tradename		7.8		(7.6	)		0.2		7.4		(3.9	)		3.5	2
Total	$	242.5	$	(145.5	)	$	97.0	$	242.1	$	(123.0	)	$	119.1

        Amortization expense for the year ended September 30, 2012 was $22.5 million. The following table presents estimated amortization expense of existing intangible assets for the succeeding years:

Fiscal Year	(in millions)
2013	$	18.3
2014		17.0
2015		15.5
2016		12.8
2017		11.6
Thereafter		21.8
Total	$	97.0

        In addition to the above, amortization of acquired intangible assets included within equity in earnings of joint ventures was $1.0 million and $3.1 million for the fiscal years ended September 30, 2012 and 2011, respectively.

        In connection with the goodwill impairment discussed above, the Company performed testing of acquired intangible assets and concluded that no impairment existed.

Reportable Segments and Geographic Information

Reportable Segments and Geographic Information

21. Reportable Segments and Geographic Information

        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 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 unaudited summarized financial information concerning the Company's reportable segments:

14. Leases

        The Company and its subsidiaries are lessees in non-cancelable leasing agreements for office buildings and equipment which expire at various dates. The related lease payments are expensed on a straight-line basis over the lease term, including, as applicable, any free-rent period during which the Company has the right to use the asset. For leases with renewal options where the renewal is reasonably assured, the lease term, including the renewal period is used to determine the appropriate lease classification and to compute periodic rental expense. The following table presents, in millions, amounts payable under non-cancelable operating lease commitments during the following fiscal years:

Year Ending September 30,
2013	$	201.6
2014		175.7
2015		139.6
2016		122.1
2017		100.4
Thereafter		319.9
Total	$	1,059.3

        Included in the above table are commitments totaling $17.0 million related to the sale-leaseback of the Company's Orange, California facility initially entered into during the year ended September 30, 2006. The sales price of this facility was $20.1 million of which $16.3 million in gain on sale-leaseback was deferred and is being amortized over the 12-year term of the lease.

        The Company also has similar non-cancelable leasing agreements that are accounted for as capital lease obligations due to the terms of the underlying leases. At September 30, 2012 and 2011, the Company had total lease obligations under capital leases of $5.9 million and $8.0 million, respectively. Rent expense for all leases for the years ended September 30, 2012, 2011 and 2010, was approximately $237.4 million, $254.5 million and $211.3 million, respectively. When the Company is required to restore leased facilities to original condition, provisions are made over the period of the lease.
