PART I

ITEM 1. BUSINESS

In this report, we use the terms “the Company,” “we,” “us” and “our” to refer to AECOM 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, 2020 as “fiscal 2020” and the fiscal year ended September 30, 2021 as “fiscal 2021.”

Overview

We are a leading global provider of professional infrastructure consulting services for governments, businesses and organizations throughout the world. We provide planning, consulting, architectural and engineering design, construction and program management services and investment and development services to commercial and government clients worldwide in major end markets such as transportation, facilities, environmental, energy, water and government.

According to Engineering News-Record’s (ENR’s) 2021 Design Survey, we are the second largest general architectural and engineering design firm in the world, ranked by 2020 design revenue, and we are ranked as the largest environmental engineering firm in the world. In addition, we are ranked by ENR as the leading firm in a number of design end markets, including transportation, general building and certain water-related markets, as well as the number two green design firm and the number five green contractor in the world. We utilize our scale and the strength of our workforce to create innovative solutions for our clients, including investments to accelerate the expansion of our digital services and solutions. Increasingly, clients are turning to us to shape solutions to achieve their Environmental, Social, and Governance (ESG) objectives. With our market leading capabilities, we are uniquely well suited to address these challenges.

3

Our business focuses primarily on providing fee-based planning, consulting, architectural and engineering design services and, therefore, our business is primarily driven by knowledge-based services. We primarily 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. AECOM Capital primarily derives its income from real estate development sales and management fees.

During the first quarter of fiscal 2020, we reorganized our operating and reporting structure to better align with our ongoing professional services business. This reorganization better reflected our continuing operations after the sale of our Management Services segment, the sale of our self-perform at-risk civil infrastructure and power construction businesses and the planned disposal of our oil & gas construction business. Our Management Services and self-perform at-risk construction businesses were part of our former Management Services segment and a substantial portion of our former Construction Services segment, respectively. These businesses are classified as discontinued operations in all periods presented.

We report our continuing business through three segments, each of which is described in further detail below: Americas, International, and AECOM Capital (ACAP). Such segments are organized by the differing specialized needs of the respective clients and how we manage the business. We have aggregated various operating segments into our reportable segments 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.

● Americas:  Planning, consulting, architectural and engineering design, and construction and program management services to commercial and government clients in the United States, Canada, and Latin America in major end markets such as transportation, water, government, facilities, environmental, and energy.

● International:  Planning, consulting, architectural and engineering design services and program management to commercial and government clients in Europe, the Middle East, Africa, India and the Asia-Pacific regions in major end markets such as transportation, water, government, facilities, environmental, and energy.

● AECOM Capital (ACAP):  Investments primarily in real estate projects.

Our Americas and International Segments

Our Americas and International segments comprise 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.  Our Americas segment provides services generally in the United States, Canada and Latin America.  Our International segment provides similar services generally in Europe, the Middle East, Africa and Asia-Pacific regions.

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

In addition, our industry is undergoing a digital transformation, and we are investing in digital capabilities to extend our advantages, improve overall delivery, and create distinct solutions for clients that differentiate us from competitors.  Clients are asking for innovative and more advanced solutions to increasingly complex challenges, where our digital suite of products and investments in innovation are creating a more holistic approach to our work.

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 may employ small or large project teams and, in many cases, operate as an outsourcing arrangement with our staff located at the project site.

Our AECOM Capital Segment

ACAP typically partners with investors and experienced developers as co-general partners. ACAP may, but is not required to, enter into contracts with our other AECOM affiliates to provide design, engineering, construction management, development and operations and maintenance services for ACAP funded projects. ACAP development activity is conducted through joint ventures or subsidiaries that may be consolidated or unconsolidated for financial reporting purposes depending on the extent and nature of our ownership interest. In addition, in connection with the investment activities of ACAP, AECOM or an affiliate may provide guarantees of certain financial obligations, including guarantees for completion of projects, repayment of debt, environmental indemnity obligations, and other lender required guarantees. ACAP focuses on investing in co-general partner equity opportunities with high quality partners, primarily targeting “build-to-core” investments in the top 25 U.S. markets across all property types.

Thinking and Acting Globally

AECOM is at its best when we think and act globally. Our strategy is focused on setting a new standard of excellence in the professional services industry. First, our recently simplified operating structure promotes greater connectivity and collaboration across our seven regions and five global business lines. We drive growth by prioritizing our core markets, leaning into our greatest strengths and ensuring our best talent and resources are focused on nurturing client relationships. We are transforming the way we deliver work through technology and digital platforms improving the client experience and increasing efficiency. Lastly, we are building upon our position as a leading ESG company, unified by our purpose to deliver a better world.

Environmental, Social and Governance Matters

We are committed to being a leader in environmental sustainability, social responsibility, and corporate governance.

We embrace sustainability by striving to make a positive, lasting impact on society and the environment. Sustainability is at the core of what we do and how we operate — focusing on the environmental, social and governance impact of our business. Through our projects and our operations, we have both a significant opportunity and a responsibility to protect, enhance and restore the world's natural and social systems.

7

We are committed to addressing the effects of climate change as a key priority for our sustainability program by improving resilience and working to advance ambitious greenhouse gas emissions reduction targets. We were the first company in the engineering sector to have set emissions reduction targets approved by the Science Based Targets Initiative (SBTi), designed to meet the goals of the Paris Agreement on climate change. Through this and other enterprise initiatives, we announced even more ambitious targets as part of our Sustainable Legacies strategy that include commitments to becoming net-zero in our Scope 1, 2 and 3 emissions by 2030. These commitments build upon our commitments as a signatory to the UN Global Compact.

In addition, we continue to invest in proprietary innovations and digital solutions. This includes a solution to combat globally pervasive emerging contaminants, such as our proprietary DE-FLUORO^TM water treatment solution to destroy per and polyfluoroalkyl substances (PFAS) on-site. It also includes our SewerLogic solution, which is a machine learning cloud-based digital tool that improves efficiencies of asset management and inspection services of sewer lines.

We have established an internal Global ESG Council to coordinate and drive our ESG initiatives across AECOM worldwide, and our Board, including through its Committees, has oversight over ESG matters. Additional information regarding our ESG initiatives is located on the investor relations section of our website, at https://investors.aecom.com/esg.  

Human Capital Management

Our principal asset is our employees, and large percentages of our employees have technical and professional backgrounds and undergraduate and/or advanced degrees. At the end of our fiscal 2021, we employed approximately 51,000 persons, of whom approximately 17,000 were employed in the United States. Over 2,000 of our domestic employees are covered by collective bargaining agreements or by specific labor agreements, which expire upon completion of the relevant project. We believe that the quality and level of service that our professionals deliver are among the highest in our industry.

We are committed to enhancing our position as a leading employer in our industry. The foundation of our continuing success is our ability to attract, recruit and retain the industry’s best, diverse talent by offering a compelling employee value proposition that promises competitive pay and benefits, flexibility and a foundation of learning and career growth, an inclusive culture that supports well-being and encourages collaboration and innovation, and a shared commitment to our values and purpose. This understanding informs our approach to managing our human capital resources. Our human capital objectives and initiatives are overseen by our Board as per our Corporate Governance Guidelines.

Health and Safety. Core to our corporate values is safeguarding our people and fostering a culture of caring that promotes the wellbeing of our employees, contractors and business partners. We safeguard our people, projects and reputation by striving for zero employee injuries and illnesses, while operating and delivering our work responsibly and sustainably. We maintain our industry’s best-in-class lost workday case and recordable incident rates, and our safety performance is consistently recognized by key clients across the regions where we work as well as by recognized safety organizations. AECOM supports community uptake of approved Covid-19 vaccines as the most effective measure to end the current global pandemic and we strongly encourage that employees receive an approved vaccine. Employees supporting clients through site visits and face-to-face meetings abide by client-worksite Covid-19 protocols, which may include documentation establishing proof of immunization or proof of negative Covid-19 test. Throughout the pandemic we have taken and will continue to take critical steps to keep our people, clients and communities safe from Covid-19.

Equity, diversity and inclusion. We are committed to advancing equity, diversity and inclusion in our organization and within our industry. We build safe and respectful work environments where our employees are invited to bring their talents, backgrounds and expertise to bear on some of the world’s most complex problems and where every person has the opportunity to thrive personally and professionally. We are advancing efforts globally in four key areas: 1) Building a workforce reflective of the communities we serve through our recruitment efforts, building leadership accountability, and partnering with nonprofit organizations and universities to build the talent pipeline for the future, 2) Enriching communities through pro-bono work, volunteerism, philanthropy and strategic partnerships, 3) Expanding understanding and empathy among employees through employee resource groups, ED&I events and celebrations, and family-friendly benefit policies, and 4) Prioritizing social equity and impact in every project we pursue and the innovative solutions we deliver.

Freedom to Grow. As a result of the pandemic, the concept of work is changing, employee values are shifting, and offices are no longer the only workplace. A key factor in our ability to attract and retain top talent is offering flexible or hybrid work options. Freedom to Grow is our global framework designed to support employees in finding the balance and flexibility they need to do their best, deliver for clients, and bring their whole selves to work. Starting with giving employees flexibility in where and when they work – a desire expressed in surveys conducted during the pandemic – employees and managers can evaluate work schedules and work locations and align on an approach that prioritizes client and team responsibilities while supporting individual needs. The guiding rule is that if an arrangement works for the employee, the manager, the team, and most importantly, the client, then the arrangement works for AECOM.

9

Workplace of the future. Drawing on the experiences of our teams and our clients during the pandemic, we developed a space and technology framework that allows for seamless connectivity between home offices, company offices and client sites, and a new global workplace design that accounts for reduced capacity requirements and prioritizes sustainability, collaboration and engagement. We are also advancing initiatives to enable the digital delivery of our work by establishing best practices and governance protocols for the digital reuse of core elements of the design process.

Employee experience. We continue to enhance our employee programs, workplace culture and digital technologies to support employees and managers with tools and resources they need to deliver excellence for their clients and teams. These efforts include employee safety, health and wellness programs to support employees and their families during the Covid-19 pandemic and beyond, expanding access to and developing professional and technical training programs through our online education portal, AECOM University, delivering new digital tools to enhance connectivity, networking and collaborations  among employees, and advancing frontline manager and leadership development programs.

Purpose and impact. As the world’s trusted infrastructure consulting firm and a leader in environmental, social and corporate governance (ESG), we are determined and well-positioned to deliver positive, impactful and Sustainable Legacies for our company, our communities and our planet. Through strategic nonprofit partnerships, pro-bono work, skills-based volunteering and philanthropy, and Blueprint for a Better World, our corporate responsibility platform, we are focused on delivering access to safe and secure infrastructure to those who need it most, creating opportunity for the leaders of tomorrow and protecting our planet so that our company can fulfill its purpose to deliver a better world.  As part of the Blueprint pro-bono program, our technical experts partnered with nonprofit organizations in their local communities to provide critical design, engineering and infrastructure solutions. In addition, we have maintained our commitment to our enterprise strategic nonprofit partners – Engineers Without Borders and Water for People.

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)
	2021				2020				2019
U.S. Federal Government	$	1,026.6	8	%	$	1,027.8	8	%	$	1,273.7	9	%
U.S. State and Local Governments		2,797.9	21			2,709.7	20			2,696.6	20
Non-U.S. Governments		1,896.8	14			1,869.0	14			2,031.5	15
Subtotal Governments		5,721.3	43			5,606.5	42			6,001.8	44
Private Entities (worldwide)		7,619.6	57			7,633.5	58			7,640.7	56
Total	$	13,340.9	100	%	$	13,240.0	100	%	$	13,642.5	100	%

No single client accounted for 10% or more of our revenue in any of the past five fiscal years. Approximately 8%, 8% and 9% of our revenue was derived through direct contracts with agencies of the U.S. federal government in the years ended September 30, 2021, 2020 and 2019, respectively.

Contracts

The price provisions of the contracts we undertake can be grouped into several broad categories: cost-reimbursable contracts, guaranteed maximum price contracts, and fixed-price contracts.

10

Cost-Reimbursable Contracts

Cost-reimbursable contracts include cost-plus fixed fee, cost-plus fixed rate, and time-and-materials price contracts. Under cost-plus contracts, we charge clients for our costs, including both direct and indirect costs, plus a negotiated fee or rate. We recognize revenues based on actual direct costs incurred and the applicable fixed rate or portion of the fixed fee earned as of the balance sheet date. Under time-and-materials price contracts, we negotiate hourly billing rates and charge clients based on the actual time we expend on the project. In addition, clients reimburse us for materials and other direct incidental expenditures, including payments to subcontractors, incurred in connection with our performance under the contract. Time-and-material price contracts may also have a fixed-price element in the form of not-to-exceed or guaranteed maximum price provisions.

Some 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 generally recognize revenue to the extent of costs actually incurred plus a proportionate 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 and a significant reversal of the award fee is not probable. Once an award is received, the estimated or accrued fees are adjusted to the actual award amount.

Some 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.

Guaranteed Maximum Price Contracts

Guaranteed maximum price contracts (GMP) share many of the same contract provisions as cost-plus and fixed-price contracts. As with cost-plus contracts, clients are provided a disclosure of all project costs, and a lump sum percentage fee is separately identified. We provide clients with a guaranteed price for the overall project (adjusted for change orders issued by clients) and a schedule including the expected completion date. Cost overruns or costs associated with project delays in completion could generally be our responsibility. For many of our commercial or residential GMP contracts, the final price is generally not established until we have subcontracted a substantial percentage of the trade contracts with terms consistent with the master contract, and we have negotiated additional contract limitations, such as waivers of consequential damages as well as aggregate caps on liabilities and liquidated damages. Revenue is recognized for GMP contracts as project costs are incurred relative to total estimated project costs.

Fixed-Price Contracts

Fixed-price contracts include both lump-sum and fixed-unit price contracts. Under lump-sum contracts, we perform all the work under the contract for a specified price. Lump-sum contracts are typically subject to price adjustments if the scope of the project changes or unforeseen conditions arise. Under fixed-unit price contracts, we perform a 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. Revenue is recognized for fixed-price contracts using the input method measured on a cost-to-cost basis.

Some of our fixed-price contracts require us to provide surety bonds or parent company guarantees to assure our clients that their project will be completed in accordance with the terms of the contracts as further disclosed in Note 18—Commitments and Contingencies. In such cases, we may require our primary subcontractors to provide similar performance bonds and guarantees and to be adequately insured, and we may flow down the terms and conditions set forth in our agreement on to our subcontractors. There may be risks associated with completing these projects profitably if we are not able to perform our services within the fixed-price contract terms.

11

For the year ended September 30, 2021, our revenue was comprised of 40%, 34%, and 26% cost-reimbursable, guaranteed maximum price, and fixed-price contracts, respectively.

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 represents revenue we expect to realize for work completed by our consolidated subsidiaries and our proportionate share of work to be performed by unconsolidated joint ventures. 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. We report transaction price allocated to remaining unsatisfied performance obligations (RUPO) of $18.7 billion, as described in Note 4, Revenue Recognition, in the notes to our consolidated financial statements. The most significant differences between our backlog and RUPO are backlog contains revenue we expect to record in the future where we have been awarded the work, but the contractual agreement has not yet been signed, unconsolidated joint venture backlog where we expect to realize income through equity earnings rather than revenue, and revenue related to service contracts that extend beyond the termination provision of those contracts, where RUPO requires us to assume the contract will be terminated at its earliest convenience. Accordingly, RUPO is $19.9 billion lower than backlog. 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. Backlog fluctuates due to the timing of when contracts are awarded and contracted and when contract revenue is recognized. Many of our contracts require us to provide services over more than one year. Our backlog for the year ended September 30, 2021 decreased $2.6 billion, or 6.3%, to $38.6 billion as compared to $41.2 billion for the corresponding period last year, primarily due to a decrease in our construction management business.

The following summarizes backlog (in billions):

	September 30,
	2021		2020
Backlog:
Americas segment	$	33.4	$	36.5
International segment		5.2		4.7
Total backlog	$	38.6	$	41.2

Competition

The markets we serve are highly fragmented and we compete with a large number of regional, national and international companies. We have numerous competitors, ranging from small private firms to multi-billion dollar companies, some of which have greater financial resources or that are 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. The technical and professional aspects of our services generally do not require large upfront capital expenditures and, therefore, provide limited barriers against new competitors.

We believe that we are well positioned to compete in our markets because of our reputation, our cost effectiveness, our long-term client relationships, our extensive network of offices, our employee expertise, and our broad range of services. In addition, as a result of our extensive national and international network, we are able to offer our clients localized knowledge and expertise, as well as the support of our worldwide professional staff. In addition, through investments in technology and innovation, we are able to bring advanced solutions to clients.

12

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 lowest revenue 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.

Risk Management and Insurance

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, a group of senior members of our risk management team evaluates risk through internal risk analyses of higher-risk projects, contracts or other business decisions. We maintain insurance covering professional liability and claims involving bodily injury and property damage. 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.

Regulations

Our business is impacted by environmental, health and safety, government procurement, anti-bribery and other government regulations and requirements. Below is a summary of some of the significant regulations that impact our business.

Environmental, Health and Safety.  Our business involves the planning, design, program management, construction management, and operations and maintenance at various project sites, including, but not limited to, nuclear facilities, hazardous waste and Superfund sites, hydrocarbon production, distribution and transport sites, and other infrastructure-related facilities. We also regularly perform work in and around sensitive environmental areas, such as rivers, lakes and wetlands.

Significant fines, penalties and other sanctions may be imposed for non-compliance with environmental and health and safety laws and regulations, and some laws provide for joint and several strict liabilities for remediation of releases of hazardous substances, rendering a person liable for environmental damage, without regard to negligence or fault on the part of such person. These laws and regulations may expose us to liability arising out of the conduct of operations or conditions caused by others, or for our acts that were in compliance with all applicable laws at the time these acts were performed. For example, there are a number of governmental laws that strictly regulate the handling, removal, treatment, transportation and disposal of toxic and hazardous substances, such as the Comprehensive Environmental Response Compensation and Liability Act of 1980, and comparable national and state laws, that impose strict, joint and several liabilities for the entire cost of cleanup, without regard to whether a company knew of or caused the release of hazardous substances. In addition, some environmental regulations can impose liability for the entire clean-up upon owners, operators, generators, transporters and other persons arranging for the treatment or disposal of such hazardous substances related to contaminated facilities or project sites. Other federal environmental, health and safety laws affecting us include, but are not limited to, the Resource Conservation and Recovery Act, the National Environmental Policy Act, the Clean Air Act, the Clean Air Mercury Rule, the Occupational Safety and Health Act, the Toxic Substances Control Act, and the Superfund Amendments and Reauthorization Act, as well as other comparable national and state laws. Liabilities related to environmental contamination or human exposure to hazardous substances, comparable national and state laws or a failure to comply with applicable regulations could result in substantial costs to us, including cleanup costs, fines and civil or criminal sanctions, third-party claims for property damage or personal injury, or cessation of remediation activities.

13

Some of our business operations are covered by Public Law 85-804, which provides for indemnification by the U.S federal government against claims and damages arising out of unusually hazardous or nuclear activities performed at the request of the U.S. federal government. Should public policies and laws change, however, U.S. federal government indemnification may not be available in the case of any future claims or liabilities relating to hazardous activities that we undertake to perform.

Government Procurement. The services we provide to the U.S. federal government are subject to Federal Acquisition Regulation, the Truth in Negotiations Act, Cost Accounting Standards, the Services Contract Act, export controls rules and Department of Defense (DOD) security regulations, as well as many other laws and regulations. These laws and regulations affect how we transact business with our clients and, in some instances, impose additional costs on our business operations. A violation of specific laws and regulations could lead to fines, contract termination or suspension of future contracts. Our government clients can also terminate, renegotiate, or modify any of their contracts with us at their convenience; and many of our government contracts are subject to renewal or extension annually.

Anti-Bribery and other regulations.  We are subject to the U.S. Foreign Corrupt Practices Act and similar anti-bribery laws, which generally prohibit companies and their intermediaries from making improper payments to foreign government officials for the purpose of obtaining or retaining business. The U.K. Bribery Act of 2010 prohibits both domestic and international bribery, as well as bribery across both private and public sectors. In addition, an organization that “fails to prevent bribery” committed by anyone associated with the organization can be charged under the U.K. Bribery Act unless the organization can establish the defense of having implemented “adequate procedures” to prevent bribery. To the extent we export technical services, data and products outside of the U.S., we are subject to U.S. and international laws and regulations governing international trade and exports, including, but not limited to, the International Traffic in Arms Regulations, the Export Administration Regulations, and trade sanctions against embargoed countries. We provide services to the DOD and other defense-related entities that often require specialized professional qualifications and security clearances. In addition, as engineering design services professionals, we are subject to a variety of local, state, federal, and foreign licensing and permit requirements and ethics rules.

Raw Materials

We purchase most of the raw materials and components necessary to operate our business from numerous sources. However, the price and availability of raw materials and components may vary from year to year due to customer demand, production capacity, market conditions, and material shortages. While we do not currently foresee the lack of availability of any particular raw materials in the near term, prolonged unavailability of raw materials necessary to our projects and services or significant price increases for those raw materials could have a material adverse effect on our business in the near term.

Government Contracts

Generally, our government contracts are subject to renegotiation or termination of contracts or subcontracts at the discretion of the U.S. federal, state or local governments, and national governments of other countries.

Trade Secrets and Other Intellectual Property

We rely principally on trade secrets, confidentiality policies and other contractual arrangements to protect much of our intellectual property.

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 occurs, our business, financial condition or results of operations could be materially adversely affected.

Risks Related to Our Markets, Customers and Business

We face various risks related to health outbreaks such as the Covid-19 pandemic that may have material adverse effects on our business, financial position, results of operations and/or cash flows.

Our business could be materially and adversely affected by the risk, or the public perception of risk, related to a pandemic or widespread health crisis, such as the current Covid-19 pandemic. A significant outbreak, epidemic or pandemic of contagious diseases in the human population could result in a widespread health crisis adversely affecting the broader economies, financial markets and overall demand for our services. In addition, any preventative or protective actions that governments implement or that we take in respect of a global health crisis, such as travel restrictions, quarantines, or site closures, may interfere with the ability of our employees and vendors to perform their responsibilities. Such results could have a material adverse effect on our operations, business, financial condition, results of operations, or cash flows.

Our operations have been affected by a range of external factors related to the Covid-19 pandemic that are not within our control. For example, many jurisdictions have imposed a wide range of restrictions on the physical movement of our employees and vendors to limit the spread of Covid-19 and some non-essential construction and other client projects temporarily halted as a result. Extended disruptions due to the Covid-19 pandemic could further delay or limit our ability to perform services, make or receive timely payments, and impair our ability to win future contracts. Any cost increases due to Covid-19 may not be fully recoverable or adequately covered by our insurance. Our management is focused on mitigating the effects of Covid-19 on our business, which has required and will continue to require a substantial investment of their time and may delay their other efforts.

We continue to closely monitor the impact of the Covid-19 pandemic and to assess its potential effects on our business. In response to the Covid-19 pandemic, we implemented various measures to mitigate the impact of the pandemic on our business but given the dynamic nature of these circumstances, the full impact of the Covid-19 pandemic cannot be reasonably estimated at this time. The extent to which our business, financial condition, results of operations, or cash flows are affected by Covid-19 will depend in part on future developments which cannot be accurately predicted and are uncertain. The impact of the Covid-19 pandemic depends upon various uncertainties, including the ultimate geographic spread of the virus, the severity of the virus, the duration of the outbreak, and actions that may be taken by governmental authorities to contain the virus. This situation is changing continually, and additional effects may arise that we are not presently aware of or that we currently do not consider to be significant risks to our operations. If we are not able to respond to and manage the impact of such events effectively, our business and financial condition could be negatively impacted.

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 markets we serve are highly fragmented and we compete with a large number of regional, national and international companies. These competitors may 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. In addition, the technical and professional aspects of some of our services generally do not require large upfront capital expenditures and provide limited barriers against new competitors.

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, price 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, increased margin pressure and loss of revenue, profitability and market share.

15

Demand for our services is cyclical and vulnerable to sudden economic downturns and reductions in government and private industry spending. If economic conditions remain uncertain and/or weaken, our revenue and profitability could be adversely affected.

Demand for our services is cyclical and may be vulnerable to sudden economic downturns, interest rate fluctuations and reductions in government and private industry spending that result in clients delaying, curtailing or canceling proposed and existing projects. For example, the Covid-19 pandemic reduced demand for some of our services and impacted certain client spending. 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 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 portion of our revenue is derived from contracts with agencies and departments of national, state, and local governments. During fiscal 2021 and 2020, approximately 43% and 42%, respectively, of our revenue was derived from contracts with government entities.

Most government contracts are subject to such government’s budgetary approval process. Legislatures typically appropriate funds for a given program on an annual basis, even though contract performance may take more than one year. In addition, public-supported financing such as state and local municipal bonds may be only partially raised to support existing infrastructure projects. 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 fiscal year. These appropriations, and the timing of payment of appropriated amounts, may be influenced by, among other things, the state of the economy, a government shutdown, 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. Similarly, the impact of an economic downturn on governments, including as a result of the Covid-19 pandemic, may make it more difficult for them to fund infrastructure projects. 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.

If we are unable to win or renew government contracts during regulated procurement processes, our operations and financial results would be harmed.

Government contracts are awarded through a regulated procurement process. The federal government has awarded multi-year contracts with pre-established terms and conditions, such as indefinite delivery contracts, that generally require those contractors that have previously been awarded the indefinite delivery contract to engage in an additional competitive bidding process before a task order is issued. The federal government has also awarded federal contracts based on a low-price, technically acceptable criteria emphasizing price over qualitative factors, such as past performance. As a result of these competitive pricing pressures, our profit margins on future federal contracts may be reduced and may require us to make sustained efforts to reduce costs in order to realize profits under government contracts. If we are not successful in reducing the amount of costs we incur, our profitability on government contracts will be negatively impacted. In addition, we may not be awarded government contracts because of existing government policies designed to protect small businesses and under-represented minority contractors. Our inability to win or renew government contracts during regulated procurement processes could harm our operations and reduce our profits and revenues.

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, for some assignments, the U.S. government may attempt to “insource” the services to government employees rather than outsource to a contractor. 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.

16

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. 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. For example, from time to time we may be subject to qui tam lawsuits, which typically allege that we have made false statements or certifications in connection with claims for payment, or improperly retained overpayments, from the government. These suits may remain under seal (and hence, be unknown to us) for some time while the government decides whether to intervene on behalf of the qui tam plaintiff.

An extended government shutdown, payment delays or reduced demand for our services may have a material impact on our results of operation and financial condition.

An extended government shutdown could significantly reduce demand for our services, delay payment and result in workforce reductions that may have a material adverse effect on our results of operation and financial condition. Moreover, a prolonged government shutdown could result in program cancellations, disruptions and/or stop work orders and could limit the government’s ability to effectively process and our ability to perform government contracts and successfully compete for new work.

Risks Related to our Capital Structure

The agreements governing our debt contain a number of restrictive covenants which will limit our ability to finance future operations, acquisitions or capital needs or engage in other business activities that may be in our interest.

The Credit Agreement and the indentures governing our debt contain a number of significant covenants that impose operating and other restrictions on us and our subsidiaries. Such restrictions affect or will affect and, in many respects, limit or prohibit, among other things, our ability and the ability of some of our subsidiaries to:

● incur additional indebtedness;

● create liens;

● pay dividends and make other distributions in respect of our equity securities;

● redeem or repurchase our equity securities;

● distribute excess cash flow from foreign to domestic subsidiaries;

● make investments or other restricted payments;

● sell assets;

● enter into transactions with affiliates; and

● effect mergers or consolidations.

In addition, our Credit Agreement requires us to comply with a consolidated interest coverage ratio and consolidated leverage ratio. Our ability to comply with these ratios may be affected by events beyond our control. These restrictions could limit our ability to plan for or react to market or economic conditions or meet capital needs or otherwise restrict our activities or business plans, and could adversely affect our ability to finance our operations, acquisitions, investments or strategic alliances or other capital needs or to engage in other business activities that would be in our interest. A breach of any of these covenants or our inability to comply with the required financial ratios could result in a default under our debt instruments. If an event of default occurs, our creditors could elect to:

17

● declare all borrowings outstanding, together with accrued and unpaid interest, to be immediately due and payable;

● require us to apply all of our available cash to repay the borrowings; or

● prevent us from making debt service payments on our borrowings.

If we were unable to repay or otherwise refinance these borrowings when due, the applicable creditors could sell the collateral securing some of our debt instruments, which constitutes substantially all of our domestic and foreign, wholly owned subsidiaries’ assets.

Our variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly.

Borrowings under our Credit Agreement are at variable rates of interest and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness will increase even though the amount borrowed remains the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. A 1.00% increase in such interest rates would increase total interest expense under our Credit Agreement for the year ended September 30, 2021 by $6.2 million, including the effect of our interest rate swaps. We may, from time to time, enter into additional interest rate swaps that involve the exchange of floating for fixed rate interest payments in order to reduce interest rate volatility. However, we may not maintain interest rate swaps with respect to all of our variable rate indebtedness, and any swaps we enter into may not fully mitigate our interest rate risk and could be subject to credit risk themselves.

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

The changing nature of the global credit markets could make it more difficult for us to access funds, refinance our existing indebtedness, enter into agreements for uncommitted debt bond facilities and new indebtedness, replace our existing revolving and term credit agreements or obtain funding through the issuance of our securities. We use credit facilities to support our working capital and other 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.

Risks Related to our International Operations

The uncertainty surrounding the implementation of and effects of the United Kingdom’s proposed withdrawal from the European Union could have an adverse effect on our business and financial results.

The United Kingdom formally left the European Union on January 31, 2020, under the UK-EU Withdrawal Agreement, which also included a transition period that concluded on December 31, 2020. On January 1, 2021, the UK also left the EU Single Market and Customs Union, as well as all EU policies and international agreements. As a result, the free movement of persons, goods, services and capital between the UK and the EU ended, and the EU and the UK formed two separate markets. On December 24, 2020, the EU reached a trade agreement with the UK. The trade agreement offers UK and EU companies preferential access to each other’s markets, ensuring imported goods will be free of tariffs and quotas; however, economic relations between the UK and EU will now be on more restricted terms than existed previously. The trade agreement does not incorporate the full scope of the services sector, and businesses such as banking and finance face uncertainty. In March 2021, the UK and EU agreed on a framework for voluntary regulatory cooperation and dialogue on financial services issues between the two countries in a memorandum of understanding, which is expected to be signed after formal steps are completed, although this has not yet occurred. At this time, we cannot predict the impact that the trade agreement, the memorandum of understanding or any future agreements on services, particularly financial services, will have on our business. Our United Kingdom business is a significant part of our European operations with approximately 6,000 employees and revenues representing approximately 6% of our total revenue for the fiscal year ended September 30, 2021. The uncertainty created by Brexit may cause our customers to closely monitor their costs and reduce demand for our services and may ultimately result in new regulatory and cost challenges for our United Kingdom and global operations. Any of these events could adversely affect our United Kingdom, European and overall business and financial results.

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 2021, revenue attributable to our services provided outside of the United States to non-U.S. clients was approximately 29% of our total revenue. There are risks inherent in doing business internationally, including:

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

18

● political and economic instability, including in the Middle East and Southeast Asia;

● 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, such as retaliatory tariffs between the United States and China;

● political unrest in Hong Kong where we have a significant presence;

● impact of the Covid-19 pandemic and its related economic impacts;

● changes in regulatory practices, tariffs and taxes, such as Brexit;

● 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.

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, including the requirements to maintain accurate information and internal controls which may fall within the purview of the FCPA, its books and records provisions or its anti-bribery provisions. We operate in many parts of the world that have experienced governmental corruption to some degree; and, in some 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. 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 the Middle East, Africa, and Southeast Asia, where the 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.

Risks Related to Our Operations and Technology

Many of our project sites are inherently dangerous workplaces. Failure to maintain safe work sites and equipment could result in environmental disasters, employee deaths or injuries, reduced profitability, the loss of projects or clients and possible exposure to litigation.

Our project sites often put our employees and others in close proximity with mechanized equipment, moving vehicles, chemical and manufacturing processes, and highly regulated materials. On some project sites, we may be responsible for safety and, accordingly, we have an obligation to implement effective safety procedures. If we fail to implement these procedures or if the procedures we implement are ineffective, we may suffer the loss of or injury to our employees, as well as expose ourselves to possible litigation. As a result, our failure to maintain adequate safety standards and equipment could result in reduced profitability or the loss of projects or clients, and could have a material adverse impact on our business, financial condition, and results of operations.

19

Cybersecurity threats, information technology systems outages and data privacy incidents could adversely harm our business.

We may experience errors, outages, or delays of service in our information technology systems, which could significantly disrupt our operations, impact our clients and employees, damage our reputation, and result in litigation and regulatory fines or penalties. Various privacy and securities laws pertaining to client and employee data usage require us to manage and protect sensitive and proprietary information. For example, the European’s Union General Data Protection Regulation extends the scope of the European Union data protection laws to all companies processing data of European Union residents, regardless of the company’s location. In addition, the California Consumer Privacy Act increased the penalties for data privacy incidents.

We face threats to our information technology systems, including unauthorized access, computer hackers, computer viruses, malicious code, cyber-attacks, phishing and other cybersecurity problems and system disruptions, including possible unauthorized access to our and our clients’ proprietary information. We rely on industry-accepted security measures and technology to securely maintain all proprietary information on our information technology systems. In the ordinary course of business, we have been targeted by malicious cyber-attacks. Anyone who circumvents our security measures could misappropriate proprietary information, including information regarding us, our employees and/or our clients, or cause interruptions in our operations. Although we devote significant resources to our cybersecurity programs and have implemented security measures to protect our systems and to prevent, detect and respond to cybersecurity incidents, there can be no assurance that our efforts will prevent these threats. As these security threats continue to evolve, we may be required to devote additional resources to protect, prevent, detect and respond against system disruptions and security breaches.

We also rely in part on third-party software and information technology vendors to run our critical accounting, project management and financial information systems. We depend on our software and information technology vendors to provide long-term software and hardware support for our information systems. Our software and information technology vendors may decide to discontinue further development, integration or long-term software and hardware support for our information systems, in which case we may need to abandon one or more of our current information systems and migrate some or all of our accounting, project management and financial information to other systems, thus increasing our operational expense, as well as disrupting the management of our business operations.

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. Furthermore, while we maintain insurance that specifically covers these attacks, our coverage may not sufficiently cover all types of losses or claims that may arise.

Risks Related to Contracts and Joint Ventures

Our business and operating results could be adversely affected by losses under fixed-price or guaranteed maximum 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 addition, we may enter guaranteed maximum price contracts where we guarantee a price or delivery date. For the year ended September 30, 2021, our revenue was comprised of 40%, 34%, and 26% cost-reimbursable, guaranteed maximum price, and fixed-price contracts, respectively. Fixed-price contracts expose us to a number of risks not inherent in cost-reimbursable contracts, including underestimation of costs, ambiguities in specifications, unforeseen increases in or failures in estimating the cost of raw materials, equipment or labor, problems with new technologies, delays beyond our control, fluctuations in profit margins, failures of subcontractors to perform and economic or other changes that may occur during the contract period. United States and foreign trade policy actions and tariffs such as the 2018 tariffs on steel and aluminum imports in the United States could affect the profitability of our fixed-price construction projects. Losses under fixed-price or guaranteed contracts could be substantial and adversely impact our results of operations.

20

Our failure to meet contractual schedule or performance requirements that we have guaranteed could adversely affect our operating results.

In some circumstances, we can incur liquidated or other damages if we do not achieve project completion by a scheduled date. If we or an entity for which we have provided a guarantee fails to complete the project as scheduled and the matter cannot be satisfactorily resolved with the client, we may be responsible for cost impacts to the client resulting from any delay or the cost to complete the project. Our costs generally increase from schedule delays and/or could exceed our projections for a particular project. In addition, project performance can be affected by a number of factors beyond our control, including unavoidable delays from governmental inaction, public opposition, inability to obtain financing, weather conditions, unavailability of vendor materials, changes in the project scope of services requested by our clients, industrial accidents, environmental hazards, labor disruptions, pandemics including the current coronavirus, and other factors. Material performance problems for existing and future contracts could cause actual results of operations to differ from those anticipated by us and also could cause us to suffer damage to our reputation within our industry and client base.

We may not be able to maintain adequate surety and financial capacity necessary for us to successfully bid on and win contracts.

In line with industry practice, we are often required to provide surety bonds, standby letters of credit or corporate guarantees to our clients that indemnify them should our affiliate fail to perform its obligations under the terms of a contract. As of September 30, 2021 and September 30, 2020, we were contingently liable for $4.3 billion and $6.2 billion, respectively, in issued surety bonds primarily to support project execution and we had outstanding letters of credit totaling $483.0 million and $529.1 million, respectively. A surety may issue a performance or payment bond to guarantee to the client that our affiliate will perform under the terms of a contract. If our affiliate fails to perform under the terms of the contract, then the client may demand that the surety or another corporate affiliate provide the contracted services. In addition, we would typically have obligations to indemnify the surety for any loss incurred in connection with the bond. If a surety bond or a letter of credit is required for a particular project and we are unable to obtain an appropriate surety bond or letter of credit, we may not be able to pursue that project, which in turn could have a material adverse impact on our business, financial condition, results of operations, and cash flows.

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

Approximately 10% of our fiscal 2021 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. Sales of our services provided to our unconsolidated joint ventures were approximately 4% of our fiscal 2021 revenue. We generally do not have control of these unconsolidated joint ventures. 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 and could also affect our reputation.

We participate in joint ventures where we provide guarantees and may be adversely impacted by the failure of the joint venture or its participants to fulfill their obligations.

We have investments in and commitments to joint ventures with unrelated parties, including in connection with construction services, government services, and the investment activities of ACAP. For example, real estate and infrastructure joint ventures are inherently risky and may result in future losses since real estate markets are impacted by economic trends and government policies that we do not control. These joint ventures from time to time may borrow money to help finance their activities and in some circumstances, we are required to provide guarantees of obligations of our affiliated entities. In addition, in connection with the investment activities of ACAP, we provide guarantees of obligations, including guarantees for completion of projects, repayment of debt, environmental indemnity obligations and other lender required guarantees.

21

AECOM Capital’s real estate development and investment activities are inherently risky and may result in a future loss.

ACAP’s real estate business involves managing, sponsoring, investing in and developing commercial real estate projects and joint ventures (Real Estate Joint Ventures) that are inherently risky and may result in future losses since real estate markets are significantly impacted by economic trends and government policies that we do not control. Our registered investment adviser jointly manages and sponsors the AECOM-Canyon Equity Fund, L.P. (the “Fund”), in which the Company indirectly holds an equity interest and which also invests in and develops Real Estate Joint Ventures on behalf of its investors. Real Estate Joint Ventures rely on substantial amounts of third party borrowing to finance their development activities including completion guarantees, repayment guarantees, environmental indemnities and other lender required credit support guarantees that may be provided by AECOM or an affiliate to secure the Real Estate Joint Venture financing. Although the Fund and such Real Estate Joint Ventures have reserves that will be used to share any cost overruns of the Real Estate Joint Ventures, if such reserves are depleted, then AECOM may be required to make support payments to fund non-budgeted cost overruns on behalf of the Fund (but not on behalf of the Fund’s co-partner or any unaffiliated limited partners of the Real Estate Joint Ventures). Some of the Fund’s limited partners may be permitted to make additional equity co-investments in certain Real Estate Joint Ventures for which AECOM will provide support payments on behalf of the limited partner co-investor in the event of a cost overrun of the Real Estate Joint Venture after additional specific reserves have been depleted. AECOM’s provision of lender guarantees is contingent upon the Real Estate Joint Ventures meeting AECOM’s underwriting criteria, including an affiliate of AECOM acting as either the construction manager at risk or the owner’s representative for the project, no material adverse change in AECOM’s financial condition, and the guarantee not violating a covenant under a material AECOM agreement.

Risks Related to Laws and Regulations

Misconduct by our employees, subcontractors, partners 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’, subcontractors’, partners’ 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 procurement regulations, environmental 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, anti-competition, export control and other applicable laws or regulations. Our failure to comply with applicable laws or regulations, misconduct by any of our employees, subcontractors, partners 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.

We may be subject to substantial liabilities under environmental laws and regulations.

Our services are subject to numerous environmental protection laws and regulations that are complex and stringent. Our business involves in part the planning, design, program management, construction management, and operations and maintenance at various sites, including but not limited to, nuclear facilities, hazardous waste and Superfund sites, hydrocarbon production, distribution and transport sites, and other infrastructure-related facilities. We also regularly perform work in and around sensitive environmental areas, such as rivers, lakes and wetlands. In addition, we have contracts in support of U.S. federal government entities to destroy hazardous materials, including chemical agents and weapons stockpiles, as well as to decontaminate and decommission nuclear facilities. These activities may require us to manage, handle, remove, treat, transport and dispose of toxic or hazardous substances. We also own and operate several properties in the U.S. and Canada that have been used for the storage and maintenance of construction equipment. In the conduct of operations on these properties, and despite precautions having been taken, it is possible that there have been accidental releases of individually relatively small amounts of fuel, oils, hydraulic fluids and other fluids while storing or servicing this equipment. Such accidental releases though individually relatively small may have accumulated over time. Past business practices at companies that we have acquired may also expose us to future unknown environmental liabilities.

22

Significant fines, penalties and other sanctions may be imposed for non-compliance with environmental laws and regulations, and some environmental laws provide for joint and several strict liabilities for remediation of releases of hazardous substances, rendering a person liable for environmental damage, without regard to negligence or fault on the part of such person. These laws and regulations may expose us to liability arising out of the conduct of operations or conditions caused by others, or for our acts that were in compliance with all applicable laws at the time these acts were performed. For example, there are a number of governmental laws that strictly regulate the handling, removal, treatment, transportation and disposal of toxic and hazardous substances, such as Comprehensive Environmental Response Compensation and Liability Act of 1980, and comparable state laws, that impose strict, joint and several liabilities for the entire cost of cleanup, without regard to whether a company knew of or caused the release of hazardous substances. In addition, some environmental regulations can impose liability for the entire cleanup upon owners, operators, generators, transporters and other persons arranging for the treatment or disposal of such hazardous substances related to contaminated facilities or project sites. Other federal environmental, health and safety laws affecting us include, but are not limited to, the Resource Conservation and Recovery Act, the National Environmental Policy Act, the Clean Air Act, the Clean Air Mercury Rule, the Occupational Safety and Health Act, the Toxic Substances Control Act and the Superfund Amendments and Reauthorization Act and the Energy Reorganization Act of 1974, as well as other comparable national and state laws. Liabilities related to environmental contamination or human exposure to hazardous substances, or a failure to comply with applicable regulations could result in substantial costs to us, including cleanup costs, fines and civil or criminal sanctions, third-party claims for property damage or personal injury or cessation of remediation activities. Our continuing work in the areas governed by these laws and regulations exposes us to the risk of substantial liability.

Risks Related to Acquisitions and Divestitures

AECOM is a smaller company after the sale of our Management Services and self-perform at-risk civil infrastructure and power construction businesses and, as a result, may be more vulnerable to changing market conditions.

AECOM is a smaller company after the sale of our Management Services and self-perform at-risk civil infrastructure and power construction businesses and more reliant on our remaining business segments. Our results of operations, cash flows, working capital, effective tax rate, and financing requirements may be subject to increased volatility and our ability to fund capital expenditures, investments and service debt may be diminished. In addition, any purchase price adjustments could be unfavorable and other future proceeds owed to us as part of these transactions could be lower than we expect. We are also obligated to incur ongoing costs and retain certain legal claims that were previously allocated to the Management Services business. As a result, we may be more vulnerable to changing market conditions, which could have a material adverse effect on our business, financial condition, and results of operations.

We may be unable to successfully execute or effectively integrate acquisitions and divestitures may not occur as planned.

We regularly review our portfolio of businesses and pursue growth through acquisitions and seek to divest non-core businesses. We may not be able to complete transactions on favorable terms, on a timely basis, or at all, and during the integration of any acquisition, we may discover regulatory and compliance issues. In addition, our results of operations and cash flows may be adversely impacted by (i) the failure of acquired businesses to meet or exceed expected returns; (ii) the failure to integrate acquired businesses on schedule and/or to achieve expected synergies; (iii) the inability to dispose of non-core assets and businesses on satisfactory terms and conditions; (iv) diversion of attention and increased burdens on our employees; and (v) the discovery of unanticipated liabilities or other problems in acquired businesses for which we lack contractual protections, insurance or indemnities, or with regard to divested businesses, claims by purchasers to whom we have provided contractual indemnification. Additional difficulties we may encounter as part of the integration process include the following:

● the consequences of a change in tax treatment and the possibility that the full benefits anticipated from the acquisition or disposition will not be realized;

● any delay in the integration or disposition of management teams, strategies, operations, products and services;

● differences in business backgrounds, corporate cultures and management philosophies that may delay successful integration;

● the ability to retain key employees;

● the ability to create and enforce uniform standards, controls, procedures, policies and information systems;

● the challenge of restructuring complex systems, technology, networks and other assets in a seamless manner that minimizes any adverse impact on customers, suppliers, employees and other constituencies;

23

● potential unknown liabilities and unforeseen increased expenses or delays associated with the acquisition, including costs to integrate beyond current estimates;

● the ability to deduct or claim tax attributes or benefits such as operating losses, business or foreign tax credits; and

● the disruption of, or the loss of momentum in, each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies.

Any of these factors could adversely affect our ability to maintain relationships with customers, suppliers, employees and other constituencies or could reduce our earnings or otherwise adversely affect our business and financial results.

Our plans to divest businesses are subject to various risks and uncertainties and may not be completed in accordance with the expected plans or anticipated time frame, or at all, and will involve significant time and expense, which could disrupt or adversely affect our business.

Divesting businesses involve risks and uncertainties, such as the difficulty separating assets related to such businesses from the businesses we retain, employee distraction, the need to obtain regulatory approvals and other third-party consents, which potentially disrupts customer and vendor relationships, and the fact that we may be subject to additional tax obligations or loss of tax benefits. Because of these challenges, as well as market conditions or other factors, anticipated divestitures may take longer or be costlier or generate fewer benefits than expected and may not be completed at all. If we are unable to complete divestitures or to successfully transition divested businesses, our business and financial results could be negatively impacted. After we dispose of a business, we may retain exposure on financial or performance guarantees and other contractual, employment, pension and severance obligations, and potential liabilities that may arise under law because of the disposition or the subsequent failure of an acquirer. As a result, performance by the divested businesses or other conditions outside of our control could have a material adverse effect on our results of operations. In addition, the divestiture of any business could negatively impact our profitability because of losses that may result from such a sale, the loss of sales and operating income, or a decrease in cash flows.

Other Risks

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. Under generally accepted accounting principles 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. For example, in the year ended September 30, 2020, we recorded a noncash impairment of long-lived assets, including goodwill of $83.6 million primarily related to a decrease in the estimated recovery and fair value of reporting units with self-perform at-risk construction.

In addition, if we experience a decrease in our stock price and market capitalization 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.

We may be required to contribute additional cash to meet our significant underfunded benefit obligations associated with pension benefit plans we manage or multiemployer pension plans in which we participate.

We have defined benefit pension plans for employees in the United States, United Kingdom, Canada, Australia, and Ireland. At September 30, 2021, our defined benefit pension plans had an aggregate deficit (the excess of projected benefit obligations over the fair value of plan assets) of approximately $345.5 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 that may require us 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.

24

A multiemployer pension plan is typically established under a collective bargaining agreement with a union to cover the union-represented workers of various unrelated companies. Our collective bargaining agreements with unions require us to contribute to various multiemployer pension plans; however, we do not control or manage these plans. For the year ended September 30, 2021, we contributed $3.7 million to multiemployer pension plans. Under the Employee Retirement Income Security Act, an employer who contributes to a multiemployer pension plan, absent an applicable exemption, may also be liable, upon termination or withdrawal from the plan, for its proportionate share of the multiemployer pension plan’s unfunded vested benefit. If we terminate or withdraw from a multiemployer plan, absent an applicable exemption (such as for some plans in the building and construction industry), we could be required to contribute a significant amount of cash to fund the multiemployer plan’s unfunded vested benefit, which could materially and adversely affect our financial results; however, since we do not control the multiemployer plans, we are unable to estimate any potential contributions that could be required.

We may experience disproportionately high levels of collection risk and nonpayment if clients in specific geographic areas or industries 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 no one client accounted for over 10% of our revenue for fiscal 2021, we face collection risk as a normal part of our business where we perform services and subsequently bill our clients for such services, or when we make equity investments in majority or minority controlled large-scale client projects and other long-term capital projects before the project completes operational status or completes its project financing. 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, results of operations or accounts receivable.

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 such services. In addition, we sometimes contractually assume liability to clients on projects under indemnification or guarantee agreements. We cannot predict the magnitude of potential liabilities from the operation of our business. In addition, in the ordinary course of our business, we frequently make professional judgments and recommendations about environmental and engineering conditions of project sites for our clients. We may be deemed to be responsible for these professional judgments and recommendations if they are later determined to be inaccurate. Any unfavorable legal ruling against us could result in substantial monetary damages or even criminal violations.

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.

Unavailability or cancellation of third-party insurance coverage would increase our overall risk exposure as well as disrupt the management of our business operations.

We maintain insurance coverage from third-party insurers as part of our overall risk management strategy and because some of our contracts require us to maintain specific insurance coverage limits. If any of our third-party insurers fail, suddenly cancel our coverage or otherwise are unable to provide us with adequate insurance coverage, then our overall risk exposure and our operational expenses would increase and the management of our business operations would be disrupted. In addition, there can be no assurance that any of our existing insurance coverage will be renewable upon the expiration of the coverage period or that future coverage will be affordable at the required limits.

If we do not have adequate indemnification for our services related to nuclear materials, it could adversely affect our business and financial condition.

We provide services to the nuclear energy industry in the ongoing maintenance and modification, as well as the decontamination and decommissioning, of nuclear energy plants. Indemnification provisions under the Price-Anderson Act available to nuclear energy plant operators and contractors do not apply to all liabilities that we might incur while performing services as a radioactive materials cleanup contractor for the nuclear energy industry. If the Price-Anderson Act’s indemnification protection does not apply to our services or if our exposure occurs outside the U.S., our business and financial condition could be adversely affected either by our client’s refusal to retain us, by our inability to obtain commercially adequate insurance and indemnification, or by potentially significant monetary damages we may incur.

25

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, 2021, backlog was approximately $38.6 billion. We reported transaction price allocated to remaining unsatisfied performance obligations (RUPO) of $18.7 billion, as described in Note 4, Revenue Recognition, in the notes to our consolidated financial statements. The most significant differences between our backlog and RUPO are backlog contains revenue we expect to record in the future where we have been awarded the work, but the contractual agreement has not yet been signed, unconsolidated joint venture backlog where we expect to realize income through equity earnings rather than revenue, and revenue related to service contracts that extend beyond the termination provisions of those contracts, where guidance for the calculation of RUPO requires us to assume the contract will be terminated at its earliest convenience. Accordingly, RUPO is $19.9 billion lower than backlog. 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 canceled. 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. Often, these claims can be the subject of lengthy arbitration or litigation proceedings, and it is difficult to accurately predict when these claims will be fully resolved. When these types of events occur and unresolved claims are pending, we have used working capital in projects to cover cost overruns pending the resolution of the relevant claims. If these claims are not approved, our revenue may be reduced in future periods.

In conducting our business, we depend on other contractors, subcontractors and equipment and material providers. 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, subcontractors and equipment and material providers 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. Also, to the extent that we cannot acquire equipment and materials at reasonable costs, or if the amount we are required to pay exceeds our estimates, our ability to complete a project in a timely fashion or at a profit may be impaired. 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; we could be held responsible for such failures and/or we may be required to purchase the supplies or services from another source at a higher price. This may reduce the profit to be realized or result in a loss on a project for which the supplies or services are needed.

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 many 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, or if our reports or other work product are not in compliance with professional standards and other regulations, 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. While we include appropriate disclaimers in the reports that we prepare for our clients, once we produce such written work product, we do not always have the 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.

26

In addition, our reports and other work product may need to comply with professional standards, licensing requirements, securities regulations and other laws and rules governing the performance of professional services in the jurisdiction where the services are performed. We could be liable to third parties who use or rely upon our reports and other work product even if we are not contractually bound to those third parties. These events could in turn result in monetary damages and penalties.

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 ability to compete in our industry will be harmed if we do not retain the continued services of our senior management and key technical personnel.

We rely heavily upon the expertise and leadership of our people. 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 personnel, such as engineers, architects and project managers, who are necessary for the development of our business or to replace qualified personnel in the timeframe demanded by our clients. Also, some of our personnel hold government granted eligibility that may be required to obtain government projects. Loss of the services of, or failure to recruit senior management or key technical personnel could impact the long term performance of the Company and 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 government granted eligibility, such as security clearance credentials. 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.

Negotiations with labor unions and possible work actions could divert management attention and disrupt operations. In addition, new collective bargaining agreements or amendments to agreements could increase our labor costs and operating expenses.

We regularly negotiate with labor unions and enter into collective bargaining agreements. The outcome of any future negotiations relating to union representation or collective bargaining agreements may not be favorable to us. We may reach agreements in collective bargaining that increase our operating expenses and lower our net income as a result of higher wages or benefit expenses. In addition, negotiations with unions could divert management attention and disrupt operations, which may adversely affect our results of operations. If we are unable to negotiate acceptable collective bargaining agreements, we may have to address the threat of union-initiated work actions, including strikes. Depending on the nature of the threat or the type and duration of any work action, these actions could disrupt our operations and adversely affect our operating results.

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:

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

● vesting of exclusive authority in our Board of Directors to determine the size of the board and to fill vacancies; and

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

27

Changes in tax laws could increase our worldwide tax rate and materially affect our results of operations.

We are subject to tax laws in the U.S. and numerous foreign jurisdictions. The U.S. and many international legislative and regulatory bodies continually propose and enact legislation that could significantly impact how U.S. multinational corporations are taxed. In the U.S., the proposed legislation in the Build Back Better Act would impose a 15% minimum tax on corporate book income for corporations with profits over $1 billion, change the Global Intangible Low-Taxed Income (GILTI) regime, reduce the deduction for Foreign-Derived Intangible Income (FDII), and create a new limitation on interest deductions as well as other corporate tax reform. Due to the large scale of our U.S. and international business activities, many of these proposed changes, if enacted into law, could have an adverse impact on our worldwide effective tax rate, income tax expense and cash flows.

ITEM 1B.  UNRESOLVED STAFF COMMENTS

None.

ITEM 2.  PROPERTIES

Our corporate offices are located in approximately 9,000 square feet of space at 13355 Noel Road, Dallas, Texas. Our other offices, including smaller administrative or project offices, consist of an aggregate of approximately 7.4 million square feet worldwide. Virtually all of our offices are leased. See Note 11 in the notes to our consolidated financial statements for information regarding our lease obligations. 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. We are not always aware if we or our affiliates are under investigation or the status of such matters. 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, with the exception of the matters noted in Note 18, Commitments and Contingencies, to the financial statements contained in this report to the extent stated therein, 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 18, Commitments and Contingencies, to the financial statements contained in this report for a discussion of certain matters to which we are a party. The information set forth in such note is incorporated by reference into this Item 3. From time to time, we establish reserves for litigation when we consider it probable that a loss will occur.

ITEM 4.  MINE SAFETY DISCLOSURES

The Company does not act as the owner of any mines, but as concerning the fiscal year prior to January 2, 2021, we may have acted as a mining operator as defined under the Federal Mine Safety and Health Act of 1977 where we may have been a lessee of a mine, a person who operates, controls or supervises such mine, or an independent contractor performing services or construction of such mine. Information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95.

Overview

We are a leading global provider of professional, technical and management support services for governments, businesses and organizations throughout the world. We provide planning, consulting, architectural and engineering design, construction management services, and investment and development services to commercial and government clients worldwide in major end markets such as transportation, facilities, environmental, energy, water and government.

Our business focuses primarily on providing fee-based planning, consulting, architectural and engineering design services and, therefore, our business is labor intensive. We primarily 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. AECOM Capital primarily derives its income from real estate development sales and management fees.

During the first quarter of fiscal 2020, we reorganized our operating and reporting structure to better align with our ongoing professional services business. This reorganization better reflected our continuing operations after the sale of our Management Services segment and planned disposal of our self-perform at-risk construction businesses, including our civil infrastructure, power, and oil & gas construction businesses. Our Management Services and self-perform at-risk construction businesses were part of our former Management Services segment and a substantial portion of our former Construction Services segment, respectively. These businesses are classified as discontinued operations in all periods presented.

We report our continuing business through three segments: Americas, International, and AECOM Capital (ACAP). Such segments are organized by the differing specialized needs of the respective clients, and how we manage the business. We have aggregated various operating segments into our reportable segments 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.

Our Americas segment delivers planning, consulting, architectural and engineering design, and construction management services to commercial and government clients in the United States, Canada, and Latin America in major end markets such as transportation, water, government, facilities, environmental, and energy. Our International segment delivers planning, consulting, and architectural and engineering design services to commercial and government clients in Europe, the Middle East, Africa, and the Asia-Pacific regions in major end markets such as transportation, water, government, facilities, environmental, and energy. Revenue for these two segments is primarily derived from fees for services we provide.

Our ACAP segment primarily invests in and develops real estate projects. ACAP typically partners with investors and experienced developers as co-general partners. ACAP may, but is not required to, enter into contracts with our other AECOM affiliates to provide design, engineering, construction management, development and operations, and maintenance services for ACAP funded projects.

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, other project-related expenses and sales, general and administrative costs.

The U.S. federal government, under the Biden Administration, has proposed significant legislative and executive infrastructure initiatives that, if enacted, could have a positive impact to our infrastructure business.

Regarding our capital allocation policy,  on September 22, 2021, the Board approved an increase in our repurchase authorization to $1.0 billion. At September 30, 2021, we have approximately $1.0 billion remaining of the Board’s repurchase authorization. We intend to deploy future available cash towards stock repurchases consistent with our capital allocation policy.

32

We have exited substantially all of our self-perform at-risk construction business and expect to divest all of our remaining non-core oil and gas markets. We have substantially completed our exit of 30 countries, subject to applicable laws, as part of our ongoing plan to improve profitability and reduce our risk profile, and we continue to evaluate our geographic exposure as part of such plan.

We expect to incur restructuring costs of approximately $20 million to $30 million in fiscal 2022 primarily related to previously announced restructuring actions that are expected to deliver continued margin improvement and efficiencies. Total cash costs for these restructuring actions are expected to be approximately $20 million to $30 million.

Covid-19 Coronavirus Impacts

The impact of the coronavirus pandemic and measures to prevent its spread are affecting our businesses in a number of ways:

● The coronavirus and accompanying economic effects may reduce demand for our services and impact client spending in certain circumstances; however, the uncertain nature of the coronavirus and its duration make it difficult for us to predict and quantify such impact.

● We have restricted non-essential business travel, required or facilitated employees to work remotely where appropriate.

● The coronavirus has made estimating the future performance of our business and mitigating the adverse financial impact of these developments on our business operations more difficult.

● State and local budget shortfalls in the U.S. have negatively impacted our pipeline of pursuits and the pace of award activity.

● Certain markets, such as the U.K., Middle East, and Southeast Asia, are experiencing project delays that have impacted our performance and results.

Acquisitions

There were no acquisitions consummated during the years ended September 30, 2021, 2020 and 2019.

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.

Revenue

We generate revenue primarily by providing planning, consulting, architectural and engineering design services to 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 recognize revenue over time as performance obligations are satisfied and control over promised goods or services are transferred to our customers. We generally measure progress to completion using an input measure of total costs incurred divided by total costs expected to be incurred.

Cost of Revenue

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

Amortization Expense of Acquired Intangible Assets

Included in our cost of revenue 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.

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 our return on investments in unconsolidated joint ventures.

General and Administrative Expenses

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

Acquisition and Integration Expenses

Acquisition and integration expenses are comprised of transaction costs, professional fees, and personnel costs, including due diligence and integration activities, primarily related to business acquisitions.

Goodwill Impairment

See Critical Accounting Policies and Consolidated Results below.

Income Tax Expense (Benefit)

As a global enterprise, income tax expense/(benefit) and our effective tax rates can be affected by many factors, including changes in our worldwide mix of pre-tax losses/earnings, the effect of non-controlling interest in income of consolidated subsidiaries, the extent to which the earnings are indefinitely reinvested outside of the United States, our acquisition strategy, tax incentives and credits available to us, changes in judgment regarding the realizability of our deferred tax assets, changes in existing tax laws and our assessment of uncertain tax positions. Our tax returns are routinely audited by the taxing authorities and settlements of issues raised in these audits can also sometimes affect our effective tax rate.

Geographic Information

For geographic financial information, please refer to Note 4 and Note 19 in the notes to our consolidated financial statements found elsewhere in the Form 10-K.

Critical Accounting Policies and Estimates

Our accounting policies, including those described below, often require management to make significant estimates and assumptions using information available at the time the estimates are made. Such estimates and assumptions significantly affect various reported amounts of assets, liabilities, revenue and expenses. If future experience differs significantly from these estimates and assumptions, our results of operations and financial condition could be affected. Our most critical accounting policies and estimates are described below. We have not materially changes our estimation methodology during the period presented.

Revenue Recognition

Our accounting policies establish principles for recognizing revenue upon the transfer of control of promised goods or services to customers. We generally recognize revenues over time as performance obligations are satisfied. We generally measure our progress to completion using an input measure of total costs incurred divided by total costs expected to be incurred. In the course of providing these services, we routinely subcontract for services and incur other direct cost on behalf of our clients. These costs are passed through to clients and, in accordance with accounting rules, are included in our revenue and cost of revenue.

Revenue recognition and profit is dependent upon a number of factors, including the accuracy of a variety of estimates made at the balance sheet date, such as engineering progress, material quantities, the achievement of milestones, penalty provisions, labor productivity and cost estimates. Additionally, we are required to make estimates for the amount of consideration to be received, including bonuses, awards, incentive fees, claims, unpriced change orders, penalties and liquidated damages. Variable consideration is included in the estimate of transaction price only to the extent that a significant reversal would not be probable. We continuously monitor factors that may affect the quality of our estimates, and material changes in estimates are disclosed accordingly.

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 only to the extent that a significant reversal would not be probable. 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 and Expected Credit Losses

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 our 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

35

● General economic conditions.

In October 2020, we adopted the credit loss model that replaced the “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. Under the credit loss model, we maintain an allowance for credit losses, which represents the portion of our financial assets that we do not expect to collect over their contractual life.

Contract Assets and Contract Liabilities

Contract assets represent the contract revenue recognized but not yet billed pursuant to contract terms or accounts billed after the period end.

Contract liabilities represent the billings to date, as allowed under the terms of a contract, but not yet recognized as contract revenue using our revenue recognition policy.

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 us 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 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.

Additionally, our ACAP segment primarily invests in real estate projects.  

Income Taxes

We provide for income taxes in accordance with principles contained in ASC Topic 740, Income Taxes. Under these principles, we recognize the amount of income tax payable or refundable for the current year and deferred tax assets and liabilities for the future tax consequences of events that have been recognized in our financial statements or tax returns.

Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period when the new rate is enacted. Deferred tax assets are evaluated for future realization and reduced by a valuation allowance if it is more likely than not that a portion will not be realized.

We measure and recognize the amount of tax benefit that should be recorded for financial statement purposes for uncertain tax positions taken or expected to be taken in a tax return. With respect to uncertain tax positions, we evaluate the recognized tax benefits for recognition, measurement, derecognition, classification, interest and penalties, interim period accounting and disclosure requirements. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns.

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 for tax attributes such as operating loss and tax credit carryforwards. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and tax rates on the date of enactment of such changes to laws and tax rates.

36

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. The evaluation of the recoverability of the deferred tax asset requires the Company to weigh all positive and negative evidence to reach a conclusion that it is more likely than not that all or some portion of the deferred tax assets will not be realized. The weight given to the evidence is commensurate with the extent to which it can be objectively verified. 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 nature, frequency, and severity of cumulative financial reporting losses in recent years, the future reversal of existing temporary differences, predictability of future taxable income exclusive of reversing temporary differences of the character necessary to realize the asset, relevant carryforward periods, taxable income in carry-back years if carry-back is permitted under tax law, and prudent and feasible tax planning strategies that would be implemented, if necessary, to protect against the loss of the deferred tax asset that would otherwise expire. 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.

If future changes in judgment regarding the realizability of our deferred tax assets lead us to determine that it is more likely than not that 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 gross book-tax basis differences of our non-U.S. operations of approximately $1.5 billion because we have the ability to and intend to permanently reinvest these basis differences overseas. If we were to repatriate these basis differences, additional taxes could be due at that time.

We continually explore initiatives to better align our tax and legal entity structure with the footprint of our non-U.S. operations and we recognize the tax impact of these initiatives, including changes in assessment of its uncertain tax positions, indefinite reinvestment exception assertions and realizability of deferred tax assets, earliest in the period when management believes all necessary internal and external approvals associated with such initiatives have been obtained, or when the initiatives are materially complete.

Goodwill and Acquired Intangible Assets

Goodwill represents the excess of 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 annually for each reporting unit in the fourth quarter of the fiscal year and between annual tests, if events occur or circumstances change which suggest that goodwill should be evaluated. Such events or circumstances include significant changes in legal factors and business climate, recent losses at a reporting unit, and industry trends, among other factors. 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.

During the impairment test, 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, goodwill is impaired, and an impairment loss is recognized equal to the excess, limited to the total amount of goodwill allocated to the reporting unit.

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.

Material assumptions used in the impairment analysis included the weighted average cost of capital (WACC) percent and terminal growth rates. For example, as of September 30, 2021, a 1% increase in the WACC rate represents a $400 million decrease to the fair value of our reporting units. As of September 30, 2021, a 1% decrease in the terminal growth rate represents a $200 million decrease to the fair value of our reporting units.

37

There are inherent uncertainties related to each of the above listed assumptions, and our judgment in applying them. Changes in the assumptions used in our goodwill and intangible assets could result in impairment charges that could be material to our consolidated financial statements in any given period. We have not materially changed our estimation methodology during the periods presented.

Pension Benefit Obligations

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 $24.8 million to our international plans in fiscal 2022. Our required minimum contributions for our U.S. qualified plans are not significant. In addition, we may make additional discretionary contributions. We currently expect to contribute $11.4 million to our U.S. plans (including benefit payments to nonqualified plans and postretirement medical plans) in fiscal 2022. If the discount rate was reduced by 25 basis points, plan liabilities would increase by approximately $75.2 million. If the discount rate and return on plan assets were reduced by 25 basis points, plan expense would decrease by approximately $0.1 million and increase by approximately $3.2 million, respectively. If inflation increased by 25 basis points, plan liabilities in the United Kingdom would increase by approximately $28.8 million and plan expense would increase by approximately $1.7 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 actuaries and our investment consultants. 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, 2020 and September 30, 2021, the aggregate worldwide pension deficit decreased from $428.4 million to $345.5 million due to increased discount rates. If the various plans do not experience future investment gains to reduce this shortfall, the deficit will be reduced by additional contributions.

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.

38

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, 2021 increased $100.9 million, or 0.8%, to $13,340.9 million as compared to $13,240.0 million for the corresponding period last year.

The increase in revenue for the year ended September 30, 2021 was primarily attributable to increases in our Americas segment of $94.8 million and in our International segment of $10.9 million, as discussed further below.

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 clients and, in accordance with industry practice and GAAP, are included in our revenue and cost of revenue. Because these pass through revenues can change significantly from project to project and period to period, changes in revenue may not be indicative of business trends. Pass through revenues for the years ended September 30, 2021 and 2020 were $7.2 billion and $7.1 billion, respectively. Pass through revenue as a percentage of total revenue was 54% during the year ended September 30, 2021 and the year ended September 30, 2020.

Gross Profit

Our gross profit for the year ended September 30, 2021 increased $88.8 million, or 12.5%, to $798.4 million as compared to $709.6 million for the corresponding period last year. For the year ended September 30, 2021, gross profit, as a percentage of revenue, increased to 6.0% from 5.4% in the year ended September 30, 2020.

Gross profit changes were due to the reasons noted in Americas and International reportable segments below.

Equity in Earnings of Joint Ventures

Our equity in earnings of joint ventures for the year ended September 30, 2021 was $35.0 million as compared to $48.8 million in the corresponding period last year.

40

The decrease in earnings of joint ventures for the year ended September 30, 2021 compared to the same period in the prior year is primarily due to decreased earnings in our Americas and AECOM Capital segments.

General and Administrative Expenses

Our general and administrative expenses for the year ended September 30, 2021 decreased $33.6 million, or 17.8%, to $155.0 million as compared to $188.6 million for the corresponding period last year. For the year ended September 30, 2021, general and administrative expenses as a percentage of revenue decreased to 1.2% from 1.5% in the year ended September 30, 2020.

The decrease in general and administrative expenses was primarily due to the execution of restructuring actions taken by management to increase profitability and simplify our operating structure as well as accelerated depreciation of a project management tool recorded in the prior year that did not repeat in the current year.

Restructuring Costs

Since the first quarter of fiscal 2019, we have been implementing a restructuring plan to improve profitability. During the fiscal year ended September 30, 2021, we incurred restructuring expenses of $48.8 million, primarily related to costs optimizing our cost structure and reducing overhead costs. During the year ended September 30, 2020, we incurred restructuring expenses of $188.3 million, primarily related to the same matters.

Other Income

Our other income for the year ended September 30, 2021 increased $6.5 million to $17.6 million as compared to $11.1 million for the corresponding period last year.

Other income is primarily comprised of interest income and net periodic pension adjustments.

Interest Expense

Our interest expense for the year ended September 30, 2021 was $238.4 million as compared to $160.0 million for the corresponding period last year.

The increase in interest expense for the year ended September 30, 2021 was primarily due to a $117.5 million prepayment premium related to the redemption of our remaining unsecured 5.875% Senior Notes due 2024 during the three months ended June 30, 2021.

Income Tax Expense

Our income tax expense for the year ended September 30, 2021 was $89.0 million compared to $45.7 million for the year ended September 30, 2020. The increase in tax expense for the current period compared to the corresponding period last year was due primarily to the tax impacts of an increase in overall pre-tax income of $176.2 million, tax expense of $13.2 million related to an audit settlement, and a tax benefit of $31.7 million related to the release of a valuation allowance during fiscal 2020, partially offset by a tax benefit of $25.9 million related to a corporate tax rate change in the United Kingdom.

During the third quarter of fiscal 2021, the United Kingdom enacted a corporate tax rate increase from 19% to 25% beginning April 2023 requiring deferred tax assets and liabilities to be remeasured. The remeasurement resulted in a $25.9 million tax benefit.

During the third quarter of fiscal 2021, we partially settled our U.S. federal audit for fiscal 2015 and 2016 and recorded tax expense of $13.2 million due primarily to changes in tax attributes.

During fiscal 2020, management approved a tax planning strategy and we restructured certain operations in Canada which resulted in the release of a valuation allowance related to net operating losses and other deferred tax assets in the amount of $31.7 million.

41

We are currently under tax audit in several jurisdictions including the U.S. and believe the outcomes which are reasonably possible within the next twelve months, including lapses in statutes of limitations, could result in future adjustments, but will not result in a material change in the liability for uncertain tax positions.

We regularly integrate and consolidate our business operations and legal entity structure, and such internal initiatives could impact the assessment of uncertain tax positions, indefinite reinvestment assertions and the realizability of deferred tax assets.

Net Loss From Discontinued Operations

During the first quarter of fiscal 2020, management approved a plan to dispose via sale our Management Services business and our self-perform at-risk construction businesses. As a result of these strategic actions, the Management Services and self-perform at-risk construction businesses were classified as discontinued operations. That classification was applied retrospectively for all periods presented.

Net loss from discontinued operations decreased $223.8 million to $116.8 million from $340.6 million for the years ended September 30, 2021 and 2020, respectively. The decrease in net loss from discontinued operations for the year ended September 30, 2021 was primarily due to fewer losses recorded on sales of the power and civil infrastructure businesses in fiscal year 2021 than impairment losses recorded in fiscal year 2020. Net loss from discontinued operations for the year ended September 30, 2020 was primarily due to a $161.9 million gain recorded on the disposal of our Management Services business. The gain was offset by impairment of goodwill of approximately $83.6 million related to the self-perform at-risk construction business, and a $247.2 million loss related to the remeasurement of the businesses within discontinued operations based on estimated fair values less costs to sell.

Net Income (Loss) Attributable to AECOM

The factors described above resulted in the net income attributable to AECOM of $173.2 million for the year ended September 30, 2021, as compared to the net loss attributable to AECOM of $186.4 million for the year ended September 30, 2020.

Revenue

Revenue for our Americas segment for the year ended September 30, 2021 increased $94.8 million, or 0.9%, to $10,226.3 million as compared to $10,131.5 million for the corresponding period last year.

The increase in revenue for the year ended September 30, 2021 was primarily driven by increased activity in our construction management of high-rise buildings in New York City.

Gross Profit

Gross profit for our Americas segment for the year ended September 30, 2021 increased $51.1 million, or 8.8%, to $631.6 million as compared to $580.5 million for the corresponding period last year. As a percentage of revenue, gross profit increased to 6.2% of revenue for the year ended September 30, 2021 from 5.7% in the corresponding period last year.

The increase in gross profit and gross profit as a percentage of revenue for the year ended September 30, 2021 were primarily due to reduced costs and a more efficient operating structure resulting from a realigned overhead and delivery structure, better operational execution, investments in technology, and shared service centers to enhance efficiencies.

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 common stock, and refinancing or 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 twelve months. We expect to spend approximately $30 million to $40 million in restructuring costs in fiscal 2022 associated with previously announced restructuring actions that are expected to deliver continued margin improvement and efficiencies.

Generally, we do not provide for U.S. taxes or foreign withholding taxes on gross book-tax basis differences in our non-U.S. subsidiaries because such basis differences are able to and intended to be reinvested indefinitely. At September 30, 2021, we have determined that we will continue to indefinitely reinvest the earnings of some foreign subsidiaries and, therefore, we will continue to account for these undistributed earnings based on our existing accounting under ASC 740 and not accrue additional tax outside of the one-time transition tax required under the Tax Cuts and Jobs Act that was enacted on December 22, 2017. Determination of the amount of any unrecognized deferred income tax liability on this temporary difference is not practicable because of the complexities of the hypothetical calculation. Based on the available sources of cash flows discussed above, we anticipate we will continue to have the ability to permanently reinvest these remaining amounts.

At September 30, 2021, cash and cash equivalents, including cash and cash equivalents included in current assets held for sale, were $1,234.8 million, a decrease of $583.4 million, or 32.1%, from $1,818.2 million at September 30, 2020. The decrease in cash and cash equivalents was primarily attributable to cash used to repurchase common stock and cash disposed with the sales of the at-risk power and civil infrastructure construction businesses.

Net cash provided by operating activities was $704.7 million for the year ended September 30, 2021 as compared to $329.6 million for the year ended September 30, 2020. The year over year improvement in operating cash flow was partly due to sales of the Management Services business in the second quarter of fiscal 2020, the power construction business in the first quarter of 2021 and the civil infrastructure business in the second quarter of fiscal 2021, which led to a net favorable year over year impact to operating cash flow of approximately $284.1 million when comparing the year ended September 30, 2021 with the prior year. The remaining increase in operating cash flow in the year ended September 30, 2021 compared to the prior year was attributable to an increase in earnings adjusted for non-cash items of approximately $132.8 million offset by a decrease in the change in working capital of approximately $41.9 million for the year ended September 30, 2021 compared to the prior year. The sale of trade receivables to financial institutions during the year ended September 30, 2021 provided a net benefit of $90.2 million as compared to a net unfavorable impact of $143.3 million during the year ended September 30, 2020. We expect to continue to sell trade receivables in the future as long as the terms continue to remain favorable to us.

44

Net cash used in investing activities was $421.1 million for the year ended September 30, 2021, as compared to net cash provided by investing activities of $2,037.4 million for the year ended September 30, 2020. Cash flow from investing activities decreased primarily due to the change in proceeds, net of cash disposed, from the sales of the at-risk power and civil infrastructure construction businesses during the year ended September 30, 2021, which was an outflow of $265.9 million, compared to the $2,218.9 million of proceeds, net of cash disposed, received from the sale of the Management Services business in year ended September 30, 2020. Capital expenditures, net of proceeds from disposals, were $121.4 million in the year ended September 30, 2021 compared to $110.8 million in the year ended September 30, 2020. The increase in net capital expenditures in fiscal year 2021 was primarily due to an increase in investments in information technology compared to the prior year.

Net cash used in financing activities was $872.5 million for the year ended September 30, 2021, as compared to $1,628.0 million for the year ended September 30, 2020. The decrease from the prior year was primarily attributable to debt repayment using the proceeds from the sale of the Management Services business in the year ended September 30, 2020, offset by increased stock repurchases under the Stock Repurchase Program during the year ended September 30, 2021. Total borrowings under our credit agreement may vary during the period as we regularly draw and repay amounts to fund working capital.

Working Capital

Working capital, or current assets less current liabilities, decreased $788.1 million, or 54.7%, to $651.8 million at September 30, 2021 from $1,439.9 million at September 30, 2020. Net accounts receivable and contract assets, net of contract liabilities, decreased to $2,929.9 million at September 30, 2021 from $3,535.3 million at September 30, 2020. The change in working capital is primarily due to the change in cash and cash equivalents during the year ended September 30, 2021, as described above.

Days Sales Outstanding (DSO), which includes net accounts receivable and contract assets, net of contract liabilities, was 76 days at September 30, 2021 compared to 93 days at September 30, 2020.

In Note 4, Revenue Recognition, in the notes to our consolidated financial statements, a comparative analysis of the various components of accounts receivable is provided. Except for claims, substantially all contract assets are expected to be billed and collected within twelve months.

Contract assets 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. Award fees in contract assets 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.

Credit Agreement

On February 8, 2021, we entered into the 2021 Refinancing Amendment to the Credit Agreement (the “Credit Agreement”), pursuant to which we amended and restated our Syndicated Credit Facility Agreement, dated as of October 17, 2014 (as amended prior to February 8, 2021, the “Original Credit Agreement”), between the Company, as borrower, Bank of America, N.A., as administrative agent, and other parties thereto. The Credit Agreement consists of a $1,150,000,000 revolving credit facility (the “Revolving Credit Facility”) and a $246,968,737.50 term loan A facility (the “Term A Facility,” together with the Revolving Credit Facility, the “Credit Facilities”), each of which mature on February 8, 2026. The outstanding loans under the Term A Facility were borrowed in U.S. dollars. Loans under the Revolving Credit Facility may be borrowed, and letters of credit thereunder may be issued, in U.S. dollars or in certain foreign currencies. The proceeds of the Revolving Credit Facility may be used from time to time for ongoing working capital and for other general corporate purposes. The proceeds of the Revolving Credit Facility and the Term A Loan facility borrowed on February 8, 2021 were used to refinance the existing revolving credit facility and the existing term loan facility under the Original Credit Agreement and pay related fees and expenses. The Credit Agreement permits us to designate certain of its subsidiaries as additional co-borrowers from time to time. Currently, there are no co-borrowers under the Credit Facilities.

The applicable interest rate under the Credit Agreement is calculated at a per annum rate equal to, at our option, (a) the Eurocurrency Rate (as defined in the Credit Agreement) plus an applicable margin (the “LIBOR Applicable Margin”), which is currently at 1.50% or (b) the Base Rate (as defined in the Credit Agreement) plus an applicable margin (the “Base Rate Applicable Margin” and together with the LIBOR Applicable Margin, the “Applicable Margins”), which is currently at 0.50%. The Credit Agreement includes certain environmental, social and governance (ESG) metrics relating to our CO² emissions and our percentage of employees who identify as women (each, a “Sustainability Metric”). The Applicable Margins and the commitment fees for the revolving credit facility will be adjusted on an annual basis based on our achievement of preset thresholds for each Sustainability Metric.

Some of our material subsidiaries (the “Guarantors”) have guaranteed the obligations of the borrowers under the Credit Agreement, subject to certain exceptions. The borrowers’ obligations under the Credit Agreement are secured by a lien on substantially all of our assets and our Guarantors’ assets, subject to certain exceptions.

46

The Credit Agreement contains customary negative covenants that include, among other things, limitations or restrictions on our ability and certain of our subsidiaries, subject to certain exceptions, to incur liens and debt, make investments, dispositions, and restricted payments, change the nature of their business, consummate mergers, consolidations and the sale of all or substantially all of their respective assets, taken as a whole, and transact with affiliates. We are also required to maintain a consolidated interest coverage ratio of at least 3.00 to 1.00 and a consolidated leverage ratio of less than or equal to 4.00 to 1.00 (subject to certain adjustments in connection with permitted acquisitions), tested on a quarterly basis (the “Financial Covenants”). Our consolidated leverage ratio was 2.4 at September 30, 2021. As of September 30, 2021, we were in compliance with the covenants of the Credit Agreement.

The Credit Agreement contains customary affirmative covenants, including, among other things, compliance with applicable law, preservation of existence, maintenance of properties and of insurance, and keeping proper books and records. The Credit Agreement contains customary events of default, including, among other things, nonpayment of principal, interest or fees, cross-defaults to other debt, inaccuracies of representations and warranties, failure to perform covenants, events of bankruptcy and insolvency, change of control and unsatisfied judgments, subject in certain cases to notice and cure periods and other exceptions.

On April 13, 2021, we entered into Amendment No. 10 to the Credit Agreement, pursuant to which the lenders thereunder provided a secured term “B” credit facility (the “Term B Facility”) to the Company in an aggregate principal amount of $700,000,000. The Term B Facility matures on April 13, 2028. The proceeds of the Term B Facility were used to fund the purchase price, fees and expenses in connection with our cash tender offer to purchase up to $700,000,000 aggregate purchase price (not including any accrued and unpaid interest) of our outstanding 5.875% Senior Notes due 2024.

The Term B Facility is subject to the same affirmative and negative covenants and events of default as the Term A Facility previously incurred pursuant to the existing Credit Agreement (except that the Financial Covenants in the Credit Agreement do not apply to the Term B Facility). The applicable interest rate for the Term B Facility is calculated at a per annum rate equal to, at our option, (a) the Eurocurrency Rate (as defined in the Credit Agreement) plus 1.75% or (b) the Base Rate (as defined in the Credit Agreement) plus 0.75%.

On June 25, 2021, we entered into Amendment No. 11 to the Credit Agreement, pursuant to which lenders have provided us with an additional $215,000,000 in aggregate principal amount under the Term A Facility. We used the net proceeds from the increase in the Term A Facility (together with cash on hand), to (i) redeem all of our remaining 5.875% Senior Notes due 2024 and (ii) pay fees and expenses related to such redemption.

At September 30, 2021 and September 30, 2020, letters of credit totaled $5.2 million and $19.0 million, respectively, under our revolving credit facilities. As of September 30, 2021 and September 30, 2020, we had $1,144.8 million and $1,331.0 million, respectively, available under our revolving credit facility.

2024 Senior Notes

On October 6, 2014, we completed a private placement offering of $800,000,000 aggregate principal amount of the unsecured 5.875% Senior Notes due 2024 (the “2024 Notes”).

On June 25, 2021, we redeemed the remaining principal amount of the 2024 Notes outstanding at such time. The redemption price of the 2024 Notes was 115.108% of the remaining outstanding aggregate principal amount, amounting to $217.5 million, plus accrued and unpaid interest. The amounts paid were funded using the proceeds from the additional draw down from the Term A Facility described above and cash on hand. The redemption of the 2024 Notes in the third quarter of fiscal 2021 resulted in a $117.5 million prepayment premium, which was included in interest expense.

2027 Senior Notes

On February 21, 2017, we completed a private placement offering of $1,000,000,000 aggregate principal amount of our unsecured 5.125% Senior Notes due 2027 (the “2027 Senior Notes”). On June 30, 2017, we completed an exchange offer to exchange the unregistered 2027 Senior Notes for registered notes, as well as related guarantees.

47

As of September 30, 2021, the estimated fair value of the 2027 Senior Notes was approximately $1,104.5 million. The fair value of the 2027 Senior Notes as of September 30, 2021 was derived by taking the mid-point of the trading prices from an observable market input (Level 2) in the secondary bond market and multiplying it by the outstanding balance of the 2027 Senior Notes. Interest is payable on the 2027 Senior Notes at a rate of 5.125% per annum. Interest on the 2027 Senior Notes is payable semi-annually on March 15 and September 15 of each year, commencing on September 15, 2017. The 2027 Senior Notes will mature on March 15, 2027.

At any time and from time to time prior to December 15, 2026, we may redeem all or part of the 2027 Senior Notes, at a redemption price equal to 100% of their principal amount, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest to the redemption date. On or after December 15, 2026, we may redeem all or part of the 2027 Senior Notes at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest to the redemption date.

The indenture pursuant to which the 2027 Senior Notes were issued contains customary events of default, including, among other things, payment default, exchange default, failure to provide notices thereunder and provisions related to bankruptcy events. The indenture also contains customary negative covenants.

We were in compliance with the covenants relating to the 2027 Senior Notes as of September 30, 2021.

URS Senior Notes

In connection with the 2014 acquisition of the URS Corporation (URS), we assumed the URS 5.00% Senior Notes due 2022 (the “2022 URS Senior Notes”).

The remaining $248.5 million principal amount of the 2022 URS Senior Notes were fully redeemed on August 31, 2020 using proceeds from a $248.5 million secured delayed draw term loan facility under the Credit Agreement, at a redemption price that was 106.835% of the principal amount outstanding plus accrued and unpaid interest. The August 31, 2020 redemption resulted in a $17.0 million prepayment premium, which was included in interest expense during the year ended September 30, 2020.

Other Debt and Other Items

Other debt consists primarily of obligations under capital leases and loans, and unsecured credit facilities. Our unsecured credit facilities are primarily used for standby letters of credit issued in connection with general and professional liability insurance programs and for contract performance guarantees. At September 30, 2021 and September 30, 2020, these outstanding standby letters of credit totaled $478.5 million and $510.1 million, respectively. As of September 30, 2021, we had $463.6 million available under these unsecured credit facilities.

Effective Interest Rate

Our average effective interest rate on our total debt, including the effects of the interest rate swap agreements and excluding the effects of prepayment premiums included in interest expense, during the years ended September 30, 2021, 2020 and 2019 was 4.4%, 5.3% and 5.1%, respectively.

Interest expense in the consolidated statements of operations included amortization of deferred debt issuance costs for the years ended September 30, 2021, 2020 and 2019 of $10.2 million, $5.4 million and $5.0 million, respectively.

Other Commitments

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. We have consolidated all joint ventures for which we have control. For all others, our portion of the earnings is recorded in equity in earnings of joint ventures. See Note 6, Joint Ventures and Variable Interest Entities, in the notes to our consolidated financial statements.

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

Under our secured revolving credit facility and other facilities discussed in Other Debt and Other Items above, as of September 30, 2021, there was approximately $483.0 million including both continuing and discontinued operations, outstanding under standby letters of credit primarily issued 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 of our pension benefit plans, measured as the difference between the fair value of plan assets and the projected benefit obligation. At September 30, 2021, our defined benefit pension plans had an aggregate deficit (the excess of projected benefit obligations over the fair value of plan assets) of approximately $345.5 million. The total amounts of employer contributions paid for the year ended September 30, 2021 were $13.7 million for U.S. plans and $25.2 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 some countries, the funding requirements are mandatory while in other countries, they are discretionary. There is a required minimum contribution for one of 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. In addition, we have collective bargaining agreements with unions that require us to contribute to various third party multiemployer pension plans that we do not control or manage. For the year ended September 30, 2021, we contributed $3.7 million to multiemployer pension plans.

Condensed Combined Financial Information

In connection with the registration of the Company’s 2014 Senior Notes that were declared effective by the SEC on September 29, 2015, AECOM became subject to the requirements of Rule 3-10 of Regulation S-X, as amended, regarding financial statements of guarantors and issuers of guaranteed securities. Both the 2024 Senior Notes and the 2027 Senior Notes are fully and unconditionally guaranteed on a joint and several basis by some of AECOM’s directly and indirectly 100% owned subsidiaries (the Subsidiary Guarantors). Other than customary restrictions imposed by applicable statutes, there are no restrictions on the ability of the Subsidiary Guarantors to transfer funds to AECOM in the form of cash dividends, loans or advances.

The following tables present condensed combined summarized financial information for AECOM and the Subsidiary Guarantors. All intercompany balances and transactions are eliminated in the presentation of the combined financial statements. Amounts provided do not represent our total consolidated amounts as of September 30, 2021 and for the twelve months then ended.

Commitments and Contingencies

We record amounts representing our probable estimated liabilities relating to claims, guarantees, litigation, audits and investigations. We rely in part on qualified actuaries to assist us in determining the level of reserves to establish for insurance-related claims that are known and have been asserted against us, and for insurance-related claims that are believed to have been incurred based on actuarial analysis, but have not yet been reported to our claims administrators as of the respective balance sheet dates. We include any adjustments to such insurance reserves in our consolidated results of operations. Our reasonably possible loss disclosures are presented on a gross basis prior to the consideration of insurance recoveries. We do not record gain contingencies until they are realized. In the ordinary course of business, we may not be aware that we or our affiliates are under investigation and may not be aware of whether or not a known investigation has been concluded.

In the ordinary course of business, we may enter into various arrangements providing financial or performance assurance to clients, lenders, or partners. Such arrangements include standby letters of credit, surety bonds, and corporate guarantees to support the creditworthiness or the project execution commitments of our affiliates, partnerships and joint ventures. Performance arrangements typically have various expiration dates ranging from the completion of the project contract and extending beyond contract completion in some circumstances such as for warranties. We may also guarantee that a project, when complete, will achieve specified performance standards. If the project subsequently fails to meet guaranteed performance standards, we may incur additional costs, pay liquidated damages or be held responsible for the costs incurred by the client to achieve the required performance standards. The potential payment amount of an outstanding performance arrangement is typically 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) may be required to complete those activities.

At September 30, 2021, we were contingently liable in the amount of approximately $483.0 million in issued standby letters of credit and $4.3 billion in issued surety bonds primarily to support project execution.

In the ordinary course of business, we enter 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.

Our investment adviser jointly manages and sponsors the AECOM-Canyon Equity Fund, L.P. (the “Fund”), in which we indirectly hold an equity interest and have an ongoing capital commitment to fund investments. At September 30, 2021, we have capital commitments of $19.3 million to the Fund over the next 7 years.

In addition, in connection with the investment activities of AECOM Capital, we provide guarantees of certain contractual obligations, including guarantees for completion of projects, repayment of debt, environmental indemnity obligations and other lender required guarantees.

Department of Energy Deactivation, Demolition, and Removal Project

AECOM Energy and Construction, Inc., an Ohio corporation, a former affiliate of the Company (“Former Affiliate”) executed a cost-reimbursable task order with the Department of Energy (DOE) in 2007 to provide deactivation, demolition and removal services at a New York State project site that, during 2010, experienced contamination and performance issues. In February 2011, the Former Affiliate and the DOE executed a Task Order Modification that changed some cost-reimbursable contract provisions to at-risk. The Task Order Modification, including subsequent amendments, required the DOE to pay all project costs up to $106 million, required the Former Affiliate and the DOE to equally share in all project costs incurred from $106 million to $146 million, and required the Former Affiliate to pay all project costs exceeding $146 million.

Due to unanticipated requirements and permitting delays by federal and state agencies, as well as delays and related ground stabilization activities caused by Hurricane Irene in 2011, the Former Affiliate was required to perform work outside the scope of the Task Order Modification. In December 2014, the Former Affiliate submitted an initial set of claims against the DOE pursuant to the Contracts Disputes Acts seeking recovery of $103 million, including additional fees on changed work scope (the “2014 Claims”). On December 6, 2019, the Former Affiliate submitted a second set of claims against the DOE seeking recovery of an additional $60.4 million, including additional project costs and delays outside the scope of the contract as a result of differing site and ground conditions (the “2019 Claims”). The Former Affiliate also submitted three alternative breach of contract claims to the 2014 and 2019 Claims that may entitle the Former Affiliate to recovery of $148.5 million to $329.4 million. On December 30, 2019, the DOE denied the Former Affiliate’s 2014 Claims. On September 25, 2020, the DOE denied the Former Affiliate’s 2019 Claims. The Company filed an appeal of these decisions on December 20, 2020 in the Court of Federal Claims. Deconstruction, decommissioning and site restoration activities are complete.

On January 31, 2020, the Company completed the sale of its Management Services business to the Purchaser including the Former Affiliate who worked on the DOE project. The Company and the Purchaser agreed that all future DOE project claim recoveries and costs will be split 10% to the Purchaser and 90% to the Company with the Company retaining control of all future strategic legal decisions.

The Company intends to vigorously pursue all claimed amounts but can provide no certainty that the Company will recover 2014 and 2019 Claims submitted against the DOE, or any additional incurred claims or costs, which could have a material adverse effect on the Company’s results of operations.

New York Department of Environmental Conservation

In September 2017, AECOM USA, Inc. was advised by the New York State Department of Environmental Conservation (DEC) of allegations that it committed environmental permit violations pursuant to the New York Environmental Conservation Law (ECL) associated with AECOM USA, Inc.’s oversight of a stream restoration project for Schoharie County which could result in substantial penalties if calculated under the ECL’s maximum civil penalty provisions. AECOM USA, Inc. disputes this claim and intends to continue to defend this matter vigorously; however, AECOM USA, Inc. cannot provide assurances that it will be successful in these efforts. The potential range of loss in excess of any current accrual cannot be reasonably estimated at this time primarily because the matter involves complex and unique environmental and regulatory issues; the project site involves the oversight and involvement of various local, state and federal government agencies; there is substantial uncertainty regarding any alleged damages; and the matter is in its preliminary stages.

51

Refinery Turnaround Project

A Former Affiliate of the Company entered into an agreement to perform turnaround maintenance services during a planned shutdown at a refinery in Montana in December 2017. The turnaround project was completed in February 2019. Due to circumstances outside of the Company's Former Affiliate’s control, including client directed changes and delays and the refinery’s condition, the Company's Former Affiliate performed additional work outside of the original contract over $90 million and is entitled to payment from the refinery owner of approximately $144 million. In March 2019, the refinery owner sent a letter to the Company’s Former Affiliate alleging it incurred approximately $79 million in damages due to the Company’s Former Affiliate’s project performance. In April 2019, the Company’s Former Affiliate filed and perfected a $132 million construction lien against the refinery for unpaid labor and materials costs. In August 2019, following a subcontractor complaint filed in the Thirteen Judicial District Court of Montana asserting claims against the refinery owner and the Company’s Former Affiliate, the refinery owner crossclaimed against the Company’s Former Affiliate and the subcontractor. In October 2019, following the subcontractor’s dismissal of its claims, the Company’s Former Affiliate removed the matter to federal court and cross claimed against the refinery owner. In December 2019, the refinery owner claimed $93.0 million in damages and offsets against the Company’s Former Affiliate. The parties have agreed on a February 28, 2022 deadline for close of discovery in this matter.

On January 31, 2020, the Company completed the sale of its Management Services business to the Purchaser including the Former Affiliate, however, the Refinery Turnaround Project, including related claims and liabilities, has been retained by the Company.

The Company intends to vigorously prosecute and defend this matter; however, the Company cannot provide assurance that the Company will be successful in these efforts. The resolution of this matter and any potential range of loss cannot be reasonably determined or estimated at this time, primarily because the matter raises complex legal issues that Company is continuing to assess.

New Accounting Pronouncements and Changes in Accounting

In February 2016, the Financial Accounting Standards Board (FASB) issued new accounting guidance which changes accounting requirements for leases. The new guidance requires lessees to recognize the assets and liabilities arising from all leases, including those classified as operating leases under previous accounting guidance, on the balance sheet. It also requires disclosure of key information about leasing arrangements to increase transparency and comparability among organizations. We adopted the new guidance beginning October 1, 2019 using the modified retrospective adoption method, which resulted in a downward adjustment to retained earnings of $87.8 million, net of tax. Detailed disclosures regarding the adoption and other required disclosures can be found in Note 11.

In June 2016, the FASB issued a new credit loss standard that changes the impairment model for most financial assets and some other instruments. The new guidance replaces the “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. It also simplifies the accounting model for purchased credit-impaired debt securities and loans. We adopted the new guidance effective October 1, 2020 using a modified retrospective approach that resulted in an $8.0 million, net of tax, reduction to retained earnings without restating comparative periods. Additional disclosures regarding the adoption can be found in Note 4.

52

In February 2018, the FASB issued new accounting guidance which provides entities the option to reclassify certain tax effects from other comprehensive income to retained earnings. The guidance addresses a narrow-scope financial reporting issue related to the tax effects that may become stranded in accumulated other comprehensive income as a result of the enactment of the Tax Cuts and Jobs Act (Tax Act). Under the guidance, an entity may elect to reclassify the income tax effects of the Tax Act on items within accumulated other comprehensive income to retained earnings. We determined that we will not make this election.

In August 2018, the FASB issued new accounting guidance aligning the capitalization of certain implementation costs incurred in a hosting arrangement that is a service contract with previously existing guidance for capitalizing costs incurred to develop internal-use software. The new guidance was effective for our fiscal year starting October 1, 2020. The adoption of this guidance did not have a material impact on our consolidated financial statements.

In August 2018, the FASB issued new accounting guidance amending the disclosure requirements for fair value measurements. These improvements require more disclosure for amounts measured at fair value, and specifically unobservable inputs used in fair value measurements. We adopted the new guidance starting on October 1, 2020. Adoption of the new guidance did not have a significant impact on our financial reporting process.

In August 2018, the FASB issued new accounting guidance for the disclosure requirements of defined benefit pension plans. The amended guidance eliminates certain disclosure requirements that were no longer considered to be cost beneficial. We expect to adopt the new guidance starting on October 1, 2021 and do not expect adoption of the new guidance will have a significant impact on our financial reporting process.

In March 2020, the Securities and Exchange Commission (SEC) adopted final rules that amend the financial disclosure requirement for guarantors of registered debt securities in Rule 3-10 of Regulation S-X. The new rules amend and streamline the disclosures required by guarantors and issuers of guaranteed securities. Among other things, the new disclosures may be located outside the financial statements. The new rule was effective January 4, 2021, and early adoption is permitted. We adopted the new rule on March 31, 2020. Accordingly, the revised condensed consolidating financial information is presented outside of these consolidated financial statements.

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 6 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 order to accomplish this objective, we sometimes enter 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.

53

Foreign Exchange Rates

We are exposed to foreign currency exchange rate risk resulting from our operations outside of the U.S. We use foreign currency forward contracts from time to time to mitigate foreign currency risk. 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. The functional currency of our significant foreign operations is the respective local currency.

Interest Rates

Our Credit Agreement 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, 2021 and 2020, we had $1,155.3 million and $248.5 million, respectively, in outstanding borrowings under our term credit agreements and our revolving credit facility. Interest on amounts borrowed under these agreements is subject to adjustment based on specified levels of financial performance. The applicable margin that is added to the borrowing in the base rate can range from 0.25% to 1.00% and the applicable margin that is added to borrowings in the eurocurrency rate can range from 1.25% to 2.00%. For the year ended September 30, 2021, our weighted average floating rate borrowings were $819.0 million, or $619.0 million excluding borrowings with effective fixed interest rates due to interest rate swap agreements. If short term floating interest rates had increased by 1.00%, our interest expense for the year ended September 30, 2021 would have increased by $6.2 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

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of AECOM (the "Company") as of September 30, 2021 and 2020, the related consolidated statements of operations, comprehensive income (loss), stockholders' equity and cash flows for each of the three years in the period ended September 30, 2021, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at September 30, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended September 30, 2021, 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) ("PCAOB"), the Company's internal control over financial reporting as of September 30, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated November 17, 2021 expressed an unqualified opinion thereon.

Adoption of New Accounting Standard

As discussed in Notes 2 and 11 to the consolidated financial statements, the Company changed its method of accounting for leases in 2020 due to the adoption of ASU No. 2016-02, Leases.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

56

	Revenue Recognition - Contract cost and claim recovery estimates
Description of the Matter	For the year ended September 30, 2021, contract revenues recognized by the Company were $13.3 billion. Contract revenues include $3.4 billion which relate to fixed price contracts. As described in Note 4 of the consolidated financial statements, the Company generally recognizes revenues for these contracts over time as performance obligations are satisfied.  The Company generally measures its progress to completion using an input measure of total costs incurred divided by total costs expected to be incurred. In addition, the Company’s estimate of transaction price includes variable consideration associated with claims only to the extent that a significant reversal would not be probable.
	Recognition of revenue and profit over time as performance obligations are satisfied for long-term fixed price contracts is highly judgmental as it requires the Company to prepare estimates of total contract revenue and total contract costs, including costs to complete in-process contracts. These estimates are dependent upon a number of factors, including the accuracy of estimates made at the balance sheet date, such as engineering progress, material quantities, the achievement of milestones, penalty provisions, labor productivity and cost estimates. As of September 30, 2021, significant claims included in contract assets and other non-current assets on the consolidated balance sheet were approximately $140 million. Revenue recognition relating to claims is highly judgmental as the amount has been disputed by the customer and it requires the Company to prepare estimates of amounts expected to be recovered. Changes in recovery estimates can have a material effect on the amount of revenue recognized. Auditing contract revenue recognition is complex and highly judgmental due to the variability and uncertainty associated with estimating the costs to complete and amounts expected to be recovered from claims. Changes in these estimates would have a significant effect on the amount of contract revenue recognized.
How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls that address the risk of material misstatement of contract revenue including those associated with cost to complete estimates for long-term fixed price contracts and estimates of amounts expected to be recovered from claims. For example, we tested controls over the Company’s review of estimated direct and indirect costs to be incurred and estimates of claim recovery amounts. To evaluate the Company’s determination of estimated costs to complete, we selected a sample of contracts and, among other things, inspected the executed contracts including any significant amendments; conducted interviews with and inspected questionnaires prepared by project personnel; tested key components of the cost to complete estimates, including materials, labor, and subcontractors costs; reviewed support for estimates of project contingencies; compared actual project margins to historical and expected results; and recalculated revenues recognized. To test revenue recognized relating to claims, we selected a sample of projects and evaluated the estimates made by management by reviewing documentation from management’s specialists and external counsel to support the amount of the claim. We also tested management’s estimation process by performing a lookback analysis to evaluate claims settled in the current year compared to management’s prior year estimates.

57

	Valuation of goodwill
Description of the Matter	As of September 30, 2021, the Company’s goodwill was $3.5 billion. As discussed in Note 1 of the consolidated financial statements, in the fourth quarter of each fiscal year the Company performs an annual goodwill impairment test for each reporting unit and between annual tests if events occur or circumstances change which suggest that goodwill should be evaluated. Auditing management’s goodwill impairment tests is complex and highly judgmental due to the significant estimates required to determine the fair value of the reporting units. These fair value estimates are affected by significant assumptions including revenue growth rate, profitability, weighted average cost of capital, and terminal values, which reflect management’s expectations about future market or economic conditions.
How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the Company’s goodwill impairment review process including management’s review of the significant assumptions used to determine the fair value of the reporting units. To test the estimated fair value of its reporting units, with the support of a valuation specialist, we performed audit procedures that included, among others, assessing fair value methodologies and testing the significant assumptions discussed above and the underlying data used by the Company in its analysis. We compared the significant assumptions used by management to current industry and economic trends, historical operating results, contract backlog, changes to the Company’s business operations and other relevant factors. We performed a lookback analysis to evaluate the accuracy of management’s prior year revenue and profitability estimates. We performed sensitivity analyses of significant assumptions to evaluate the changes in the fair value of the reporting units that would result from changes in the assumptions. We also tested the reconciliation of the fair value of the reporting units to the market capitalization of the Company.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of AECOM

Opinion on Internal Control over Financial Reporting

We have audited AECOM’s (the “Company”) internal control over financial reporting as of September 30, 2021, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the “COSO criteria”). In our opinion, AECOM maintained, in all material respects, effective internal control over financial reporting as of September 30, 2021, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the 2021 consolidated financial statements of the Company and our report dated November 17, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’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 are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. 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.

Definition and Limitations of Internal Control Over Financial Reporting

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.

AECOM

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.           Significant Accounting Policies

Organization—AECOM and its consolidated subsidiaries provide planning, consulting, architectural and engineering design services to commercial and government clients worldwide in major end markets such as transportation, facilities, environmental, energy, water and government. The Company also provides construction services, including building construction and energy, infrastructure and industrial construction, primarily in the Americas.

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 2021, 2020 and 2019 each contained 52, 53 and 52 weeks, respectively, and ended on October 1, October 2, and September 27, 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 joint ventures in which the Company is the primary beneficiary. All inter-company accounts have been eliminated in consolidation. Also see Note 6 regarding joint ventures and variable interest entities.

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.

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

65

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.

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.

66

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 ten to forty-five years for buildings, three to ten years for furniture and fixtures and three to twelve years for computer systems and equipment. 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 not be recoverable. The carrying amount of an asset to be held and used is not recoverable if it exceeds the sum of the undiscounted cash flows expected from the use and eventual disposition of the asset. 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 of 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. Intangible assets are amortized over the period in which the contractual or economic benefits of the intangible assets are expected to be realized.

The Company tests goodwill for impairment annually for each reporting unit in the fourth quarter of the fiscal year and between annual tests, if events occur or circumstances change which suggest that goodwill should be evaluated. Such events or circumstances include significant changes in legal factors and business climate, recent losses at a reporting unit, and industry trends, among other factors. 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.

During the impairment test, 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, goodwill is impaired, and an impairment loss is recognized equal to the excess, limited to the total amount of goodwill allocated to the reporting unit. See also Note 3.

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 fair 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 generally 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 generally the U.S. dollar, except for foreign operations where the functional currency is generally the local currency. 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.

67

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.

Noncontrolling Interests—Noncontrolling interests represent the equity investments of the minority owners in the Company’s joint ventures and other subsidiary entities that the Company consolidates in its financial statements.

Income Taxes—The Company files a consolidated U.S. federal corporate 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 the nature, frequency, and severity of cumulative financial reporting losses in recent years, the future reversal of existing temporary differences, predictability of future taxable income exclusive of reversing temporary differences of the character necessary to realize the asset, relevant carryforward periods, taxable income in carry-back years if carry-back is permitted under tax law, and prudent and feasible tax planning strategies that would be implemented, if necessary, to protect against the loss of the deferred tax asset that would otherwise expire. 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 February 2016, the Financial Accounting Standards Board (FASB) issued new accounting guidance which changes accounting requirements for leases. The new guidance requires lessees to recognize the assets and liabilities arising from all leases, including those classified as operating leases under previous accounting guidance, on the balance sheet. It also requires disclosure of key information about leasing arrangements to increase transparency and comparability among organizations. The Company adopted the new guidance beginning October 1, 2019 using the modified retrospective adoption method, which resulted in a downward adjustment to retained earnings of $87.8 million, net of tax. Detailed disclosures regarding the adoption and other required disclosures can be found in Note 11.

In June 2016, the FASB issued a new credit loss standard that changes the impairment model for most financial assets and some other instruments. The new guidance replaces the “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. It also simplifies the accounting model for purchased credit-impaired debt securities and loans. The Company adopted the new guidance effective October 1, 2020 using a modified retrospective approach that resulted in an $8.0 million, net of tax, reduction to retained earnings without restating comparative periods. Additional disclosures regarding the adoption can be found in Note 4.

In February 2018, the FASB issued new accounting guidance which provides entities the option to reclassify certain tax effects from other comprehensive income to retained earnings. The guidance addresses a narrow-scope financial reporting issue related to the tax effects that may become stranded in accumulated other comprehensive income as a result of the enactment of the Tax Cuts and Jobs Act (Tax Act). Under the guidance, an entity may elect to reclassify the income tax effects of the Tax Act on items within accumulated other comprehensive income to retained earnings. The Company has determined that it will not make this election.

In August 2018, the FASB issued new accounting guidance aligning the capitalization of certain implementation costs incurred in a hosting arrangement that is a service contract with previously existing guidance for capitalizing costs incurred to develop internal-use software. The new guidance was effective for the Company’s fiscal year starting October 1, 2020. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

In August 2018, the FASB issued new accounting guidance amending the disclosure requirements for fair value measurements. These improvements require more disclosure for amounts measured at fair value, and specifically unobservable inputs used in fair value measurements. The Company adopted the new guidance starting on October 1, 2020. Adoption of the new guidance did not have a significant impact on the Company’s financial reporting process.

68

In August 2018, the FASB issued new accounting guidance for the disclosure requirements of defined benefit pension plans. The amended guidance eliminates certain disclosure requirements that were no longer considered to be cost beneficial. The Company expects to adopt the new guidance starting on October 1, 2021 and does not expect adoption of the new guidance will have a significant impact on its financial reporting process.

In March 2020, the Securities and Exchange Commission (SEC) adopted final rules that amend the financial disclosure requirement for guarantors of registered debt securities in Rule 3-10 of Regulation S-X. The new rules amend and streamline the disclosures required by guarantors and issuers of guaranteed securities. Among other things, the new disclosures may be located outside the financial statements. The new rule was effective January 4, 2021, and early adoption is permitted. The Company adopted the new rule on March 31, 2020. Accordingly, the revised condensed consolidating financial information is presented outside of these consolidated financial statements.

3.           Discontinued Operations, Goodwill, and Intangible Assets

During the second quarter of fiscal 2020, the Company completed the sale of its Management Services business to Maverick Purchaser Sub, LLC (Purchaser), an affiliate of American Securities LLC and Lindsay Goldberg LLC. The Company received total cash consideration of $2.28 billion inclusive of the receipt in the third quarter of fiscal 2020 of $122.0 million received in connection with a favorable working capital purchase price adjustment and contingent consideration of approximately $120 million attributable to certain claims related to prior work and engagements. As a result of the sale, the Company recognized a pre-tax gain of $161.9 million. The gain on sale was included in the net loss from discontinued operations in the Consolidated Statements of Operations in fiscal year 2020.

Additionally, in the first quarter of fiscal 2020, management approved a plan to dispose via sale the Company’s self-perform at-risk construction businesses within the next year. These businesses include the Company’s civil infrastructure, power, and oil and gas construction businesses that were previously reported in the Company’s Construction Services segment. After consideration of the relevant facts, the Company concluded the assets and liabilities of its Management Services business and its self-perform at-risk construction businesses met the criteria for classification as held for sale. The Company concluded the actual and proposed disposal activities represented a strategic shift that will have a major effect on the Company’s operations and financial results and qualified for presentation as discontinued operations in accordance with FASB Accounting Standards Codification (ASC) 205-20. Accordingly, the financial results of the Management Services business and the self-perform at-risk construction businesses are presented in the Consolidated Statements of Operations as discontinued operations for all periods presented. Current and non-current assets and liabilities of these businesses not sold as of the balance sheet date are presented in the Consolidated Balance Sheets as assets and liabilities held for sale for both periods presented. Interest expense allocated to discontinued operations represents interest expenses for the discontinued operations’ finance leases and term loans, which were required to be settled upon the sale of the Management Services business.

During the first quarter of fiscal 2021, the Company completed the sale of its power construction business to CriticalPoint Capital, LLC. The Company recorded an additional pre-tax loss on the sale of  $17.3 million in fiscal 2021 related to payments for post-closing working capital adjustments.

The Company also completed the sale of its civil infrastructure construction business to affiliates of Oroco Capital in the second quarter of fiscal 2021. During the second quarter of fiscal 2021, the Company recorded a $32.8 million loss related to the sale of its civil infrastructure construction businesses. Under the terms of the sale agreement, the Company made the required cash payments and delivered the cash and cash equivalents, including cash in consolidated joint ventures, on the balance sheet at closing. As a result, the Company recorded the net cash movement of the sale as a use of cash in the investing section of its statement of cash flows.

69

During the second quarter of fiscal 2020, the Company identified indicators of impairment for the self-perform at-risk construction business. Specifically, the Company's forecast for its Oil and Gas business decreased significantly from the prior period due primarily to the volatility in global oil prices, which negatively impacted forecasts for future revenues and earnings. As a result, the Company assessed the Oil and Gas business for impairment and determined the fair value of the disposal group was lower than its carrying value. Fair value was estimated using Level 3 inputs, such as forecasted cash flows. Accordingly, the Company recorded impairment losses for that business' goodwill of approximately $83.6 million and intangible assets of approximately $5.7 million. These impairment losses were recorded in net loss from discontinued operations on the Consolidated Statements of Operations in fiscal year 2020.

During the fourth quarter of fiscal 2020, the Company recorded a $247.2 million loss related to the remeasurement of its self-perform at-risk construction businesses to fair value less cost to sell. Fair value was estimated using Level 3 inputs, such as forecasted cash flows, and Level 2 inputs, including bid prices from potential buyers.

4.           Revenue Recognition

The Company follows accounting principles for recognizing revenue upon the transfer of control of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. The Company generally recognizes revenues over time as performance obligations are satisfied. The Company generally measures its progress to completion using an input measure of total costs incurred divided by total costs expected to be incurred. 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 GAAP, are included in the Company’s revenue and cost of revenue. These pass through revenues for the years ended September 30, 2021, 2020 and 2019 were $7.2 billion, $7.1 billion and $7.4 billion, respectively.

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, such as engineering progress, material quantities, the achievement of milestones, penalty provisions, labor productivity and cost estimates. Additionally, the Company is required to make estimates for the amount of consideration to be received, including bonuses, awards, incentive fees, claims, unpriced change orders, penalties, and liquidated damages. Variable consideration is included in the estimate of the transaction price only to the extent that a significant reversal would not be probable. Management continuously monitors factors that may affect the quality of its estimates, and material changes in estimates are disclosed accordingly. Costs attributable to claims are treated as costs of contract performance as incurred.

The following summarizes the Company’s major contract types:

Cost Reimbursable Contracts

Cost reimbursable contracts include cost-plus fixed fee, cost-plus fixed rate, and time-and-materials price contracts. Under cost-plus contracts, the Company charges clients for its costs, including both direct and indirect costs, plus a negotiated fee or rate. The Company recognizes revenue based on actual direct costs incurred and the applicable fixed rate or portion of the fixed fee earned as of the balance sheet date. Under time-and-materials price 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 materials and other direct incidental expenditures incurred in connection with its performance under the contract. The Company may apply a practical expedient to recognize revenue in the amount in which it has the right to invoice if its right to consideration is equal to the value of performance completed to date.

72

Guaranteed Maximum Price Contracts (GMP)

GMP contracts share many of the same contract provisions as cost-plus and fixed-price contracts. As with cost-plus contracts, clients are provided a disclosure of all the project costs, and a lump sum or percentage fee is separately identified. The Company provides clients with a guaranteed price for the overall project (adjusted for change orders issued by clients) and a schedule including the expected completion date. Cost overruns or costs associated with project delays in completion could generally be the Company’s responsibility. For many of the Company’s commercial or residential GMP contracts, the final price is generally not established until the Company has subcontracted a substantial percentage of the trade contracts with terms consistent with the master contract, and it has negotiated additional contractual limitations, such as waivers of consequential damages as well as aggregate caps on liabilities and liquidated damages. Revenue is recognized for GMP contracts as project costs are incurred relative to total estimated project costs.

Fixed-Price Contracts

Fixed price contracts include both lump-sum and fixed-unit price contracts. Under lump-sum contracts, the Company performs all the work under the contract for a specified fee. Lump-sum contracts are typically subject to price adjustments if the scope of the project changes or unforeseen conditions arise. Under fixed-unit price contracts, the Company performs a 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. Revenue is recognized for fixed-price contracts using the input method measured on a cost-to-cost basis.

The following tables present the Company’s revenues disaggregated by revenue sources:

	Fiscal Year Ended
	September 30,		September 30,		September 30,
	2021		2020		2019
	(in millions)
Cost reimbursable	$	5,319.4	$	5,734.5	$	5,958.2
Guaranteed maximum price		4,582.7		3,896.8		3,962.6
Fixed price		3,438.8		3,608.7		3,721.7
Total revenue	$	13,340.9	$	13,240.0	$	13,642.5

	Fiscal Year Ended
	September 30,		September 30,		September 30,
	2021		2020		2019
	(in millions)
Americas	$	10,228.3	$	10,138.3	$	10,390.8
Europe, Middle East, Africa		1,588.1		1,620.3		1,752.1
Asia Pacific		1,524.5		1,481.4		1,499.6
Total revenue	$	13,340.9	$	13,240.0	$	13,642.5

As of September 30, 2021, the Company had allocated $18.7 billion of transaction price to unsatisfied or partially satisfied performance obligations, of which approximately 55% is expected to be satisfied within the next twelve months.  

Contract liabilities represent amounts billed to clients in excess of revenue recognized to date. The Company recognized revenue of $692.0 million and $592.7 million during the years ended September 30, 2021 and 2020, respectively, that was included in contract liabilities as of September 30, 2020 and 2019, respectively.

73

The Company’s timing of revenue recognition may not be consistent with its rights to bill and collect cash from its clients. Those rights are generally dependent upon advance billing terms, milestone billings based on the completion of certain phases of work or when services are performed. The Company’s accounts receivable represent amounts billed to clients that have yet to be collected and represent an unconditional right to cash from its clients. Contract assets represent the amount of contract revenue recognized but not yet billed pursuant to contract terms or accounts billed after the balance sheet date. Contract liabilities represent billings as of the balance sheet date, as allowed under the terms of a contract, but not yet recognized as contract revenue pursuant to the Company’s revenue recognition policy.  

Net accounts receivable consisted of the following:

	Fiscal Year Ended
	September 30,		September 30,
	2021		2020
	(in millions)
Billed	$	2,181.1	$	2,467.3
Contract retentions		531.2		531.3
Total accounts receivable—gross		2,712.3		2,998.6
Allowance for doubtful accounts and credit losses		(92.8)		(77.9)
Total accounts receivable—net	$	2,619.5	$	2,920.7

Substantially all contract assets as of September 30, 2021 and September 30, 2020 are expected to be billed and collected within twelve months, except for claims. Significant claims recorded in contract assets and other non-current assets were approximately $140 million and $170 million as of September 30, 2021 and September 30, 2020, respectively. The asset related to the Deactivation, Demolition, and Removal Project retained from the Purchaser discussed in Note 18 is presented in prepaid expense and other current assets from continuing operations in the Consolidated Balance Sheet. Contract retentions represent amounts invoiced to clients where payments have been withheld from progress payments until the contracted work has been completed and approved by the client. These retention agreements vary from project to project and could be outstanding for several months or years.

On October 1, 2020, the Company adopted accounting pronouncements issued by the FASB regarding the changes to the way in which entities estimate credit losses for most financial assets, including accounts receivable and contract assets. The new guidance requires the Company to maintain an allowance for credit losses, which represent the portion of its financial assets that it does not expect to collect over their contractual life. The Company considers a broad range of information to estimate expected credit losses including the related ages of past due balances, projections of credit losses based on historical trends, and collection history and credit quality of its clients. Negative macroeconomic trends or delays in payment of outstanding receivables could result in an increase in the estimated credit losses.

No single client accounted for more than 10% of the Company’s outstanding receivables at September 30, 2021 and September 30, 2020.

The Company sold trade receivables to financial institutions, of which $263.6 million and $166.6 million were outstanding as of September 30, 2021 and September 30, 2020, respectively. The Company does not retain financial or legal obligations for these receivables that would result in material losses. The Company’s ongoing involvement is limited to the remittance of customer payments to the financial institutions with respect to the sold trade receivables.

74

5.           Property and Equipment

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

	Fiscal Year Ended
	September 30,		September 30,		Useful Lives
	2021		2020		(years)
	(in millions)
Building and land	$	14.4	$	11.5	10	-	45
Leasehold improvements		351.2		343.2	1	-	20
Computer systems and equipment		602.1		557.4	3	-	12
Furniture and fixtures		112.7		134.8	3	-	10
Total		1,080.4		1,046.9
Accumulated depreciation and amortization		(681.5)		(665.2)
Property and equipment, net	$	398.9	$	381.7

Depreciation expense for the fiscal years ended September 30, 2021, 2020 and 2019 were $143.6 million, $163.4 million, and $137.5 million, respectively. Depreciation is calculated 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 term of the lease or its estimated useful life.

6.           Joint Ventures and Variable Interest Entities

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

Some of the Company’s joint ventures have no employees and minimal operating expenses. For these joint ventures, the Company’s employees perform work for the joint venture, which is then billed to a third-party customer by the joint venture. These joint ventures function as pass through entities to bill the third-party customer. For consolidated joint ventures of this type, the Company records the entire amount of the services performed and the costs associated with these services, including the services provided by the other joint venture partners, in the Company’s 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 on the consolidation of variable interest entities (VIEs) that requires companies to utilize a qualitative approach to determine whether it is the primary beneficiary of a VIE. The process for identifying the primary beneficiary of a VIE requires consideration of the factors that indicate a party has the power to direct the activities that most significantly impact the joint venture’s economic performance, including powers granted to the joint venture’s program manager, powers contained in the joint venture governing board and, to a certain extent, a company’s economic interest in the joint venture. The Company analyzes its joint ventures and classifies them as either:

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

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

75

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

Contractually required support provided to the Company’s joint ventures is discussed in Note 18.

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

	September 30,		September 30,

7.           Pension Benefit Obligations

In the U.S., the Company sponsors various qualified defined benefit pension plans. Benefits under these plans generally are based on the employee’s years of creditable service and compensation; however, all U.S. defined benefit plans are closed to new participants and have frozen accruals.

The Company also sponsors various non-qualified plans in the U.S.; all of these plans are frozen. 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.

Funding requirements for each pension plan are determined based on the local laws of the country where such pension plan resides. In certain countries, the funding requirements are mandatory while in other countries, they are discretionary. The Company currently intends to contribute $24.8 million to the international plans in fiscal 2022. The required minimum contributions for U.S. plans are not significant. In addition, the Company may make discretionary contributions. The Company currently intends to contribute $11.4 million to U.S. plans in fiscal 2022.

Expected long-term rate of return on plan assets	6.80	%	3.95	%	7.30	%	4.03	%	7.00	%	4.43	%

Pension costs are determined using the assumptions as of the beginning of the plan year. 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 2021 and pension plan asset allocation, both U.S. and international, as of September 30, 2021 and 2020:

					Percentage of Plan Assets

The Company’s domestic and foreign plans seek a competitive rate of return relative to an appropriate level of risk depending on the funded status and obligations of each plan and typically employ both active and passive investment management strategies. The Company’s risk management practices include diversification across asset classes and investment styles and periodic rebalancing toward asset allocation targets. The target asset allocation selected for each plan reflects a risk/return profile that the Company believes is appropriate relative to each plan’s liability structure and return goals.  

80

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 6.80% and 3.95% weighted-average long-term rate of return on assets assumption for the fiscal year ended September 30, 2021 for U.S. and non-U.S. plans, respectively.

As of September 30, 2021, the fair values of the Company’s pension plan assets by major asset categories were as follows:

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

For 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, not traded on an active exchange, 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, 2021, there were no material changes to the valuation techniques.

Common collective funds are valued based on net asset value (NAV) per share or unit as a practical expedient as reported by the fund manager, multiplied by the number of shares or units held as of the measurement date. Accordingly, these NAV-based investments have been excluded from the fair value hierarchy. These collective investment funds have minimal redemption notice periods and are redeemable daily at the NAV, less transaction fees, without significant restrictions. There are no significant unfunded commitments related to these investments.

82

Multiemployer Pension Plans

The Company participates in construction-industry multiemployer pension plans. Generally, the plans provide defined benefits to substantially all employees covered by collective bargaining agreements. Under the Employee Retirement Income Security Act, a contributor to a multiemployer plan is liable, upon termination or withdrawal from a plan, for its proportionate share of a plan’s unfunded vested liability. The Company’s aggregate contributions to these multiemployer plans were $3.7 million and $4.0 million for the years ended September 30, 2021 and 2020, respectively. At September 30, 2021 and 2020, none of the plans in which the Company participates are individually significant to its consolidated financial statements.

Credit Agreement

On February 8, 2021, the Company entered into the 2021 Refinancing Amendment to the Credit Agreement (the “Credit Agreement”), pursuant to which the Company amended and restated its Syndicated Credit Facility Agreement, dated as of October 17, 2014 (as amended prior to February 8, 2021, the “Original Credit Agreement”), between the Company, as borrower, Bank of America, N.A., as administrative agent, and other parties thereto. The Credit Agreement consists of a $1,150,000,000 revolving credit facility (the “Revolving Credit Facility”) and a $246,968,737.50 term loan A facility (the “Term A Facility,” together with the Revolving Credit Facility, the “Credit Facilities”), each of which mature on February 8, 2026. The outstanding loans under the Term A Facility were borrowed in U.S. dollars. Loans under the Revolving Credit Facility may be borrowed, and the Letters of Credit thereunder may be issued, in U.S. dollars or certain foreign currencies. The proceeds of the Revolving Credit Facility may be used from time to time for ongoing working capital and for other general corporate purposes. The proceeds of the Revolving Credit Facility and the Term A Loan facility borrowed on February 8, 2021 were used to refinance the existing revolving credit facility and the existing term loan facility under the Original Credit Agreement and to pay related fees and expenses. The Credit Agreement permits and the Company to designate certain of its subsidiaries as additional co-borrowers from time to time. Currently, there are no co-borrowers under the Credit Facilities.

83

The applicable interest rate under the Credit Agreement is calculated at a per annum rate equal to, at the Company’s option, (a) the Eurocurrency Rate (as defined in the Credit Agreement) plus an applicable margin (the “LIBOR Applicable Margin”), which is currently at 1.50% or (b) the Base Rate (as defined in the Credit Agreement) plus an applicable margin (the “Base Rate Applicable Margin” and together with the LIBOR Applicable Margin, the “Applicable Margins”), which is currently at 0.50%. The Credit Agreement includes certain environmental, social and governance (ESG) metrics relating to the Company’s CO² emissions and its percentage of employees who identify as women (each, a “Sustainability Metric”). The Applicable Margins and the commitment fees for the revolving credit facility will be adjusted on an annual basis based on the Company’s achievement of preset thresholds for each Sustainability Metric.

Some of the Company’s material subsidiaries (the “Guarantors”) have guaranteed the Company’s obligations of the borrowers under the Credit Agreement, subject to certain exceptions. The borrowers’ obligations under the Credit Agreement are secured by a lien on substantially all of the Company’s assets and its Guarantors’ assets, subject to certain exceptions.

The Credit Agreement contains customary negative covenants that include, among other things, limitations on the ability of the Company and certain of its subsidiaries, subject to certain exceptions, to incur liens and debt, make investments, dispositions, and restricted payments, change the nature of their business, consummate mergers, consolidations and the sale of all or substantially all of their respective assets, taken as a whole, and transact with affiliates. The Company is also required to maintain a consolidated interest coverage ratio of at least 3.00 to 1.00 and a consolidated leverage ratio of less than or equal to 4.00 to 1.00 (subject to certain adjustments in connection with permitted acquisitions), tested on a quarterly basis (the “Financial Covenants”). The Company’s consolidated leverage ratio was 2.4 at September 30, 2021. As of September 30, 2021, the Company was in compliance with the covenants of the Credit Agreement.

The Credit Agreement contains customary affirmative covenants, including, among other things, compliance with applicable law, preservation of existence, maintenance of properties and of insurance, and keeping proper books and records. The Credit Agreement contains customary events of default, including, among other things, nonpayment of principal, interest or fees, cross-defaults to other debt, inaccuracies of representations and warranties failure to perform covenants, events of bankruptcy and insolvency, change of control and unsatisfied judgments, subject in certain cases to notice and cure periods and other exceptions.

On April 13, 2021, the Company entered into Amendment No. 10 to the Credit Agreement, pursuant to which the lenders thereunder provided a secured term “B” credit facility (the “Term B Facility”) to the Company in an aggregate principal amount of $700,000,000. The Term B Facility matures on April 13, 2028. The proceeds of the Term B Facility were used to fund the purchase price, fees and expenses in connection with the Company’s cash tender offer to purchase up to $700,000,000 aggregate purchase price (not including any accrued and unpaid interest) of its outstanding 5.875% Senior Notes due 2024.

The Term B Facility is subject to the same affirmative and negative covenants and events of default as the Term A Facility previously incurred pursuant to the existing Credit Agreement (except that the Financial Covenants in the Credit Agreement do not apply to the Term B Facility). The applicable interest rate for the Term B Facility is calculated at a per annum rate equal to, at the Company’s option, (a) the Eurocurrency Rate (as defined in the Credit Agreement) plus 1.75% or (b) the Base Rate (as defined in the Credit Agreement) plus 0.75%.

On June 25, 2021, the Company entered into Amendment No. 11 to the Credit Agreement, pursuant to which the lenders have provided to the Company an additional $215,000,000 in aggregate principal amount under the Term A Facility. The Company used the net proceeds from the increase in the Term A Facility (together with cash on hand), to (i) redeem all of the Company’s remaining 5.875% Senior Notes due 2024 and (ii) pay fees and expenses related to such redemption.

At September 30, 2021 and September 30, 2020, letters of credit totaled $5.2 million and $19.0 million, respectively, under the Company’s revolving credit facilities. As of September 30, 2021 and September 30, 2020, the Company had $1,144.8 million and $1,331.0 million, respectively, available under its revolving credit facility.

2024 Senior Notes

On October 6, 2014, the Company completed a private placement offering of $800,000,000 aggregate principal amount of the unsecured 5.875% Senior Notes due 2024 (the “2024 Notes”).

On June 25, 2021, the Company redeemed the remaining principal amount of the 2024 Notes outstanding at such time. The redemption price of the 2024 Notes was 115.108% of the remaining outstanding aggregate principal amount, amounting to $217.5 million, plus accrued and unpaid interest. The amounts paid were funded using the proceeds from the additional draw down from the Term A Facility described above and cash on hand. The redemption of the 2024 Notes in the third quarter of fiscal 2021 resulted in a $117.5 million prepayment premium, which was included in interest expense.

2027 Senior Notes

On February 21, 2017, the Company completed a private placement offering of $1,000,000,000 aggregate principal amount of its unsecured 5.125% Senior Notes due 2027 (the “2027 Senior Notes”). On June 30, 2017, the Company completed an exchange offer to exchange the unregistered 2027 Senior Notes for registered notes, as well as related guarantees.

As of September 30, 2021, the estimated fair value of the 2027 Senior Notes was approximately $1,104.5 million. The fair value of the 2027 Senior Notes as of September 30, 2021 was derived by taking the mid-point of the trading prices from an observable market input (Level 2) in the secondary bond market and multiplying it by the outstanding balance of the 2027 Senior Notes. Interest is payable on the 2027 Senior Notes at a rate of 5.125% per annum. Interest on the 2027 Senior Notes is payable semi-annually on March 15 and September 15 of each year, commencing on September 15, 2017. The 2027 Senior Notes will mature on March 15, 2027.

At any time and from time to time prior to December 15, 2026, the Company may redeem all or part of the 2027 Senior Notes, at a redemption price equal to 100% of their principal amount, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest to the redemption date. On or after December 15, 2026, the Company may redeem all or part of the 2027 Notes at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest on the redemption date.

The indenture pursuant to which the 2027 Senior Notes were issued contains customary events of default, including, among other things, payment default, exchange default, failure to provide notices thereunder and provisions related to bankruptcy events. The indenture also contains customary negative covenants.

The Company was in compliance with the covenants relating to the 2027 Senior Notes as of September 30, 2021.

URS Senior Notes

In connection with the 2014 acquisition of the URS Corporation (URS), the Company assumed the URS 5.00% Senior Notes due 2022 (the “2022 URS Senior Notes”).

The remaining $248.5 million principal amount of the 2022 URS Senior Notes were fully redeemed on August 31, 2020 using proceeds from a $248.5 million secured delayed draw term loan facility under the Credit Agreement, at a redemption price that was 106.835% of the principal amount outstanding plus accrued and unpaid interest. The August 31, 2020 redemption resulted in a $17.0 million prepayment premium, which was included in interest expense during the year ended September 30, 2020.

85

Other Debt and Other Items

Other debt consists primarily of obligations under capital leases and loans, and unsecured credit facilities. The Company’s unsecured credit facilities are primarily used for standby letters of credit issued in connection with general and professional liability insurance programs and for contract performance guarantees. At September 30, 2021 and September 30, 2020, these outstanding standby letters of credit totaled $478.5 million and $510.1 million, respectively. As of September 30, 2021, the Company had $463.6 million available under these unsecured credit facilities.

Effective Interest Rate

The Company’s average effective interest rate on its total debt, including the effects of the interest rate swap agreements and excluding the effects of prepayment premiums included in interest expense, during the years ended September 30, 2021, 2020 and 2019 was 4.4%, 5.3% and 5.1%, respectively.

Interest expense in the consolidated statements of operations included amortization of deferred debt issuance costs for the years ended September 30, 2021, 2020 and 2019 of $10.2 million, $5.4 million and $5.0 million, respectively.

9.           Derivative Financial Instruments and Fair Value Measurements

The Company uses 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 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 initially reports any gain on the effective portion of a cash flow hedge as a component of accumulated other comprehensive loss. The gain or loss is subsequently reclassified to interest expense when the interest expense on the variable rate debt is recognized. If the hedged transaction becomes probable of not occurring, any gain or loss related to interest rate swap agreements would be recognized in other income.

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

September 30, 2021
Notional Amount	Notional Amount		Fixed		Effective	Expiration
Currency	(in millions)		Rate		Date	Date
USD		200.0	2.60	%	March 2018	February 2023
USD		400.0	1.349	%	February 2023	March 2028

September 30, 2020
Notional Amount	Notional Amount		Fixed		Effective	Expiration
Currency	(in millions)		Rate		Date	Date
USD		200.0	2.60	%	March 2018	February 2023

86

Subsequent to the end of the third quarter of fiscal 2021, the Company entered into new interest rate swap agreements with a notional value of $400.0 million to manage the interest rate exposure of its variable rate loans. The new swaps will become effective February 2023 and terminate in March 2028. By entering into the swap agreements, the Company converted a portion of the LIBOR rate-based liability into a fixed rate liability. The Company will pay a fixed rate of 1.349% and receive payment at the prevailing one-month LIBOR.

Other 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 were not material for the years ended September 30, 2021, 2020 and 2019.

Fair Value Measurements

The Company’s non-pension financial assets and liabilities recorded at fair values relate to derivative instruments and were not material at September 30, 2021 or 2020.

See Note 17 for accumulated balances and reporting period activities of derivatives related to reclassifications out of accumulated other comprehensive income or loss for the years ended September 30, 2021, 2020 and 2019. Additionally, there were no material losses recognized in income due to amounts excluded from effectiveness testing from the Company’s interest rate swap agreements.

10.         Concentration of Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of 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 significant 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 4 regarding the Company’s foreign revenues. In order to mitigate credit risk, the Company continually reviews the credit worthiness of its major private clients.

11.         Leases

On October 1, 2019, the Company adopted FASB ASC 842 on a modified retrospective basis, which amended the accounting standards for leases. Accordingly, the Company applied the new guidance as of the date of adoption with a cumulative-effect adjustment recorded through equity. Prior periods have not been restated as a result of the adoption. Retained earnings decreased $87.8 million due to the adoption, primarily from impairment of the right-of-use assets associated with office building leases.

The Company also applied transition elections that allow it to avoid reassessment of lease definition, classification, or direct costs relating to expired or expiring leases. Adoption of the new lease guidance did not significantly change the Company’s accounting for finance leases, which were previously referred to as capital leases.

The Company and its subsidiaries are lessees in non-cancelable leasing agreements for office buildings and equipment. Substantially all of the Company’s office building leases are operating leases, and its equipment leases are both operating and finance leases. The Company groups lease and non-lease components for its equipment leases into a single lease component but separates lease and non-lease components for its office building leases.

87

The Company recognizes a right-of-use asset and lease liability for its operating leases at the commencement date equal to the present value of the contractual minimum lease payments over the lease term. The present value is calculated using the rate implicit in the lease, if known, or the Company’s incremental secured borrowing rate. The discount rate used for operating leases is primarily determined based on an analysis the Company’s incremental secured borrowing rate, while the discount rate used for finance leases is primarily determined by the rate specified in the lease.

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. Leases with initial terms shorter than 12 months are not recognized on the balance sheet, and lease expense is recognized on a straight-line basis.

The components of lease expenses are as follows:

	Fiscal Year Ended

12.         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 13.

13.         Share-Based Payments

Defined Contribution Plans—Substantially all permanent domestic 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; however, the Company does provide an annual Company match in AECOM shares. Employees may generally reallocate their account balances on a daily basis; however, employees classified as insiders are restricted under the Company’s insider trading policy. Compensation expense for the employer contributions related to AECOM stock issued under defined contribution plans during fiscal years ended September 30, 2021, 2020 and 2019 was $26.1 million, $33.7 million, and $32.3 million, respectively.

Stock Incentive Plans—Under the 2020 Stock Incentive Plan, the Company has up to 12.1 million securities remaining available for future issuance as of September 30, 2021. 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.

The fair value of the Company’s employee stock option awards is estimated on the date of grant. The expected term of awards granted represents the period of time the awards are expected to be outstanding. The risk-free interest rate is based on U.S. Treasury bond rates with maturities equal to the expected term of the option on the grant date. The Company uses historical data as a basis to estimate the probability of forfeitures. The weighted average grant-date fair value of stock options granted during the year ended September 30, 2020 was $11.30.

The Company grants stock units to employees under its Performance Earnings Program (PEP), whereby units are earned and issued dependent upon meeting established cumulative performance objectives and vest over a three-year service period. Additionally, the Company issues restricted stock units to employees which are earned based on service conditions. The grant date fair value of PEP awards and restricted stock unit awards is that day’s closing market price of the Company’s common stock. The weighted average grant date fair value of PEP awards was $52.76, $42.99, and $27.53 during the years ended September 30, 2021, 2020 and 2019, respectively. The weighted average grant date fair value of restricted stock unit awards was $49.21, $41.90 and $27.73 during the years ended September 30, 2021, 2020 and 2019, respectively. Total compensation expense related to these share-based payments including stock options was $44.7 million, $54.2 million, and $63.8 million during the years ended September 30, 2021, 2020 and 2019, respectively. Unrecognized compensation expense related to total share-based payments outstanding as of September 30, 2021 and 2020 was $45.6 million and $50.0 million, respectively, to be recognized on a straight-line basis over the awards’ respective vesting periods which are generally three years.

14.         Income Taxes

Income before income taxes included income from domestic operations of $98.6 million, $52.9 million, and $133.0 million for fiscal years ended September 30, 2021, 2020 and 2019 and income from foreign operations of $310.2 million, $179.7 million, and $116.2 million for fiscal years ended September 30, 2021, 2020 and 2019.

During fiscal 2021, the United Kingdom enacted a corporate tax rate increase from 19% to 25% beginning April 2023 requiring deferred tax assets and liabilities to be remeasured. The remeasurement resulted in a $25.9 million tax benefit, which is included in tax rate changes above.

During fiscal 2021, the Company partially settled its U.S. federal audit for fiscal 2015 and 2016 and recorded tax expense of $13.2 million due primarily to changes in tax attributes.

During fiscal 2020, the Company approved a tax planning strategy and restructured certain operations in Canada which resulted in a release of a valuation allowance related to net operating losses and other deferred tax assets of $31.7 million. The Company is now forecasting the utilization of the net operating losses within the foreseeable future. The positive evidence was evaluated against any negative evidence to determine the valuation allowance was no longer needed.

91

During fiscal 2019, the Company reevaluated a valuation allowance of $38.1 million against foreign tax credits in the U.S. based on new positive evidence related to the issuance of regulations related to The Tax Cuts and Jobs Act (Tax Act) and forecasting the utilization of the foreign tax credits within the foreseeable future. Based on the weighing of all positive and negative evidence the Company determined that a valuation allowance was no longer needed and released the valuation allowance resulting in a tax benefit of $38.1 million.

The Company is currently under tax audit in several jurisdictions including the U.S and believe the outcomes which are reasonably possible within the next twelve months, including lapses in statutes of limitations, could result in adjustments, but will not result in a material change in the liability for uncertain tax positions.

Generally, the Company would reverse its valuation allowance in a particular tax jurisdiction if the positive evidence examined, such as projected and sustainable earnings or a tax-planning strategy that allows for the usage of the deferred tax asset, is sufficient to overcome significant negative evidence, such as large net operating loss carryforwards or a cumulative history of losses in recent years. In the United States, the valued deferred tax assets have a restricted life or use under relevant tax law and, therefore, it is unlikely that the valuation allowance related to these assets will reverse. In addition, the Company is continually investigating tax planning strategies that, if prudent and feasible, may be implemented to realize a deferred tax asset that would otherwise expire unutilized. The identification and internal/external approval (as relevant) of such a prudent and feasible tax planning strategy could cause a reduction in the valuation allowance.

The deferred tax assets (liabilities) are as follows:

	Fiscal Year Ended
	September 30,		September 30,
	2021		2020
	(in millions)
Deferred tax assets:
Compensation and benefit accruals not currently deductible	$	130.0	$	119.4

As of September 30, 2021, and 2020, the Company has available unused foreign and state net operating loss (NOL) carryforwards of $667.0 million and $710.2 million, respectively, which expire at various dates over the next several years and capital loss carryforwards of $184.1 million and $355.7 million, respectively, which expire in 2025 and 2026; some foreign NOL carryforwards never expire. In addition, as of September 30, 2021, the Company has unused federal and state research and development credits of $75.7 million and $23.4 million, respectively, and other credits of $18.1 million which expire at various dates over the next several years.

As of September 30, 2021, and 2020, gross deferred tax assets were $901.0 million and $956.6 million, respectively. The Company has recorded a valuation allowance of $197.7 million and $217.5 million as of September 30, 2021 and 2020, respectively, primarily related to foreign and state net operating loss carryforwards, capital loss carryforwards, tax credits and other deferred tax assets. The Company has performed an assessment of positive and negative evidence, including the nature, frequency, and severity of cumulative financial reporting losses in recent years, the future reversal of existing temporary differences, predictability of future taxable income exclusive of reversing temporary differences of the character necessary to realize the asset, relevant carryforward periods, taxable income in carry-back years if carry-back is permitted under tax law, and prudent and feasible tax planning strategies that would be implemented, if necessary, to protect against the loss of the deferred tax asset that would otherwise expire. 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 gross deferred tax asset (exclusive of deferred tax liabilities) of $703.3 million will be realized and, as such, no additional valuation allowance has been provided. The net decrease in the valuation allowance of $19.8 million is primarily attributable to a decrease in valuation allowances of $49.5 million related to capital losses, partially offset by increases in valuation allowances of $29.6 million for foreign unbenefitable losses.

Generally, the Company does not provide for U.S. taxes or foreign withholding taxes on gross book-tax differences in its non-U.S. subsidiaries because such basis differences of approximately $1.5 billion are able to and intended to be reinvested indefinitely. If these basis differences were distributed, foreign tax credits could become available under current law to partially or fully reduce the resulting U.S. income tax liability. There may also be additional U.S. or foreign income tax liability upon repatriation, although the calculation of such additional taxes is not practicable.

As of September 30, 2021, and 2020, the Company had a liability for unrecognized tax benefits, including potential interest and penalties, net of related tax benefit, totaling $62.8 million and $65.8 million, respectively. The gross unrecognized tax benefits as of September 30, 2021 and 2020 were $46.4 million and $47.1 million, respectively, excluding interest, penalties, and related tax benefit. Of the $46.4 million, approximately $40.1 million would be included in the effective tax rate if recognized. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows:

	Fiscal Year Ended
	September 30,		September 30,
	2021		2020
	(in millions)
Balance at the beginning of the year	$	47.1	$	55.7
Gross increase in current period’s tax positions		4.3		2.8
Gross increase in prior years’ tax positions		7.5		—
Gross decrease in prior years’ tax positions		—		(7.9)
Decrease due to settlement with tax authorities		(1.3)		(0.5)
Decrease due to lapse of statute of limitations		—		(3.5)
Gross change due to foreign exchange fluctuations		(11.2)		0.5
Balance at the end of the year	$	46.4	$	47.1

The Company classifies interest and penalties related to uncertain tax positions within the income tax expense line in the accompanying consolidated statements of operations. As of September 30, 2021, the accrued interest and penalties were $20.0 million and $3.9 million, respectively, excluding any related income tax benefits. As of September 30, 2020, the accrued interest and penalties were $18.9 million and $2.7 million, respectively, excluding any related income tax benefits.

93

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.

While it is reasonably possible that the total amounts of unrecognized tax benefits could significantly increase or decrease within the next twelve months, an estimate of the range of possible change cannot be made.

15.         Earnings Per Share

Basic earnings per share (EPS) excludes dilution and is computed by dividing net income attributable to AECOM by the weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net income attributable to AECOM 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 equity awards using the treasury stock method. For the periods presented, equity awards excluded from the calculation of potential common shares were not significant.

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

	Fiscal Year Ended
	September 30,	September 30,	September 30,
	2021	2020	2019
	(in millions)
Denominator for basic earnings per share	147.3	159.0	157.0

Other accrued expenses		310.3		436.5
	$	2,174.2	$	2,249.7

Accrued contract costs above include balances related to professional liability accruals of $736.4 million and $596.0 million as of September 30, 2021 and 2020, respectively. The remaining accrued contract costs primarily relate to costs for services provided by subcontractors and other non-employees. Liabilities recorded related to accrued contract losses were not material as of September 30, 2021 and 2020. The Company did not have material revisions to estimates for contracts where revenue is recognized using the percentage-of-completion method during the twelve months ended September 30, 2021. In the first quarter of fiscal 2019, the Company commenced a restructuring plan to improve profitability. The Company incurred restructuring expenses of $48.8 million, including personnel and other costs of $37.8 million and real estate costs of $11.0 million during the year ended September 30, 2021, of which $5.2 million was accrued and unpaid at September 30, 2021. The Company incurred restructuring expenses of $188.3 million, including personnel and other costs of $149.2 million and real estate costs of $39.1 million during the year ended September 30, 2020, of which $56.2 million was accrued and unpaid at September 30, 2020. In connection with this restructuring plan, the Company evaluated its real estate portfolio to better align with the ongoing business. The Company identified certain long-lived assets that were no longer recoverable, and recorded an impairment of $27.4 million in Impairment of long-lived assets, including goodwill during the fourth quarter of fiscal 2019. Fair value of the long-lived assets was determined primarily using Level 3 inputs, such as discounted cash flows.

18.         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’s reasonably possible loss disclosures are presented on a gross basis prior to the consideration of insurance recoveries. The Company does not record gain contingencies until they are realized. In the ordinary course of business, the Company may not be aware that it or its affiliates are under investigation and may not be aware of whether or not a known investigation has been concluded.

95

In the ordinary course of business, the Company may enter into various arrangements providing financial or performance assurance to clients, lenders, or partners. Such arrangements include standby letters of credit, surety bonds, and corporate guarantees to support the creditworthiness or the project execution commitments of its affiliates, partnerships and joint ventures. Performance arrangements typically have various expiration dates ranging from the completion of the project contract and extending beyond contract completion in certain circumstances such as for warranties. The Company may also guarantee that a project, when complete, will achieve specified performance standards. If the project subsequently fails to meet guaranteed performance standards, the Company may incur additional costs, pay liquidated damages or be held responsible for the costs incurred by the client to achieve the required performance standards. The potential payment amount of an outstanding performance arrangement is typically 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) may be required to complete those activities.

At September 30, 2021, the Company was contingently liable in the amount of approximately $483.0 million in issued standby letters of credit and $4.3 billion in issued surety bonds primarily to support project execution.

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 Company’s investment adviser jointly manages and sponsors the AECOM-Canyon Equity Fund, L.P. (the “Fund”), in which the Company indirectly holds an equity interest and has an ongoing capital commitment to fund investments. At September 30, 2021, the Company has capital commitments of $19.3 million to the Fund over the next 7 years.

In addition, in connection with the investment activities of AECOM Capital, the Company provides guarantees of certain contractual obligations, including guarantees for completion of projects, repayment of debt, environmental indemnity obligations and other lender required guarantees.

Department of Energy Deactivation, Demolition, and Removal Project

AECOM Energy and Construction, Inc., an Ohio corporation, a former affiliate of the Company (“Former Affiliate”) executed a cost-reimbursable task order with the Department of Energy (DOE) in 2007 to provide deactivation, demolition and removal services at a New York State project site that, during 2010, experienced contamination and performance issues. In February 2011, the Former Affiliate and the DOE executed a Task Order Modification that changed some cost-reimbursable contract provisions to at-risk. The Task Order Modification, including subsequent amendments, required the DOE to pay all project costs up to $106 million, required the Former Affiliate and the DOE to equally share in all project costs incurred from $106 million to $146 million, and required the Former Affiliate to pay all project costs exceeding $146 million.

Due to unanticipated requirements and permitting delays by federal and state agencies, as well as delays and related ground stabilization activities caused by Hurricane Irene in 2011, the Former Affiliate was required to perform work outside the scope of the Task Order Modification. In December 2014, the Former Affiliate submitted an initial set of claims against the DOE pursuant to the Contracts Disputes Acts seeking recovery of $103 million, including additional fees on changed work scope (the “2014 Claims”). On December 6, 2019, the Former Affiliate submitted a second set of claims against the DOE seeking recovery of an additional $60.4 million, including additional project costs and delays outside the scope of the contract as a result of differing site and ground conditions (the “2019 Claims”). The Former Affiliate also submitted three alternative breach of contract claims to the 2014 and 2019 Claims that may entitle the Former Affiliate to recovery of $148.5 million to $329.4 million. On December 30, 2019, the DOE denied the Former Affiliate’s 2014 Claims. On September 25, 2020, the DOE denied the Former Affiliate’s 2019 Claims. The Company filed an appeal of these decisions on December 20, 2020 in the Court of Federal Claims. Deconstruction, decommissioning and site restoration activities are complete.

96

On January 31, 2020, the Company completed the sale of its Management Services business to the Purchaser including the Former Affiliate who worked on the DOE project. The Company and the Purchaser agreed that all future DOE project claim recoveries and costs will be split 10% to the Purchaser and 90% to the Company with the Company retaining control of all future strategic legal decisions.

The Company intends to vigorously pursue all claimed amounts but can provide no certainty that the Company will recover 2014 and 2019 Claims submitted against the DOE, or any additional incurred claims or costs, which could have a material adverse effect on the Company’s results of operations.

New York Department of Environmental Conservation

In September 2017, AECOM USA, Inc. was advised by the New York State Department of Environmental Conservation (DEC) of allegations that it committed environmental permit violations pursuant to the New York Environmental Conservation Law (ECL) associated with AECOM USA, Inc.’s oversight of a stream restoration project for Schoharie County which could result in substantial penalties if calculated under the ECL’s maximum civil penalty provisions. AECOM USA, Inc. disputes this claim and intends to continue to defend this matter vigorously; however, AECOM USA, Inc. cannot provide assurances that it will be successful in these efforts. The potential range of loss in excess of any current accrual cannot be reasonably estimated at this time primarily because the matter involves complex and unique environmental and regulatory issues; the project site involves the oversight and involvement of various local, state and federal government agencies; there is substantial uncertainty regarding any alleged damages; and the matter is in its preliminary stages.

Refinery Turnaround Project

A Former Affiliate of the Company entered into an agreement to perform turnaround maintenance services during a planned shutdown at a refinery in Montana in December 2017. The turnaround project was completed in February 2019. Due to circumstances outside of the Company’s Former Affiliate’s control, including client directed changes and delays and the refinery’s condition, the Company’s Former Affiliate performed additional work outside of the original contract over  $90 million and is entitled to payment from the refinery owner of approximately $144 million. In March 2019, the refinery owner sent a letter to the Company’s Former Affiliate alleging it incurred approximately $79 million in damages due to the Company’s Former Affiliate’s project performance. In April 2019, the Company’s Former Affiliate filed and perfected a $132 million construction lien against the refinery for unpaid labor and materials costs. In August 2019, following a subcontractor complaint filed in the Thirteen Judicial District Court of Montana asserting claims against the refinery owner and the Company’s Former Affiliate, the refinery owner crossclaimed against the Company’s Former Affiliate and the subcontractor. In October 2019, following the subcontractor’s dismissal of its claims, the Company’s Former Affiliate removed the matter to federal court and cross claimed against the refinery owner. In December 2019, the refinery owner claimed $93.0 million in damages and offsets against the Company’s Former Affiliate. The parties have agreed on a February 28, 2022 deadline for close of discovery in this matter.

On January 31, 2020, the Company completed the sale of its Management Services business to the Purchaser including the Former Affiliate, however, the Refinery Turnaround Project, including related claims and liabilities, has been retained by the Company.

The Company intends to vigorously prosecute and defend this matter; however, the Company cannot provide assurance that the Company will be successful in these efforts. The resolution of this matter and any potential range of loss cannot be reasonably determined or estimated at this time, primarily because the matter raises complex legal issues that Company is continuing to assess.

19.         Reportable Segments and Geographic Information

During the first quarter of fiscal 2020, the Company reorganized its operating and reporting structure to better align with its ongoing professional services business. This reorganization better reflects the continuing operations of the Company after the sale of its former Management Services reportable segment and planned disposal of its self-perform at-risk construction businesses discussed in Note 3. The businesses that comprised the Company's former Management

97

Services reportable segment and the civil infrastructure, power and oil and gas construction businesses in the former Construction Services reportable segment were classified as discontinued operations. The former Design and Consulting Services reportable segment and construction management business in the former Construction Services reportable segment were reformed around geographic regions. The Americas segment provides planning, consulting, architectural and engineering design services, and construction management services to commercial and government clients in the United States, Canada, and Latin America, while the International segment provides similar professional services to commercial and government clients in Europe, the Middle East, Africa, and the Asia-Pacific regions.

The Company’s AECOM Capital (ACAP) segment primarily invests in and develops real estate projects. These reportable segments are organized by the differing specialized needs of the respective clients, and how the Company manages its business. The Company has aggregated various operating segments into its reportable segments 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. The change in reportable segments was applied to all periods presented.

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

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Based on management’s evaluation, with the participation of our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), our CEO and CFO have concluded that our disclosure controls and procedures as defined in Rules 13a-15(e) and 15(d)-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act), were effective as of September 30, 2021 to ensure that information required to be disclosed by us in this Annual Report on Form 10-K or submitted under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms, and (ii) accumulated and communicated to our management, including our principal executive and principal financial officer, as appropriate, 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, 2021, the end of our fiscal year. Our management based its assessment on criteria established in Internal Control—Integrated Framework (2013) 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, 2021. 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, 2021 included in this Annual Report on Form 10-K, and has issued an audit report with respect to the effectiveness of the Company’s internal control over financial reporting, a copy of which is included earlier in this Annual Report on Form 10-K.

Significant Accounting Policies

Significant Accounting Policies

1.           Significant Accounting Policies

Organization—AECOM and its consolidated subsidiaries provide planning, consulting, architectural and engineering design services to commercial and government clients worldwide in major end markets such as transportation, facilities, environmental, energy, water and government. The Company also provides construction services, including building construction and energy, infrastructure and industrial construction, primarily in the Americas.

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 2021, 2020 and 2019 each contained 52, 53 and 52 weeks, respectively, and ended on October 1, October 2, and September 27, 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 joint ventures in which the Company is the primary beneficiary. All inter-company accounts have been eliminated in consolidation. Also see Note 6 regarding joint ventures and variable interest entities.

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.

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.

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 ten to forty-five years for buildings, three to ten years for furniture and fixtures and three to twelve years for computer systems and equipment. 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 not be recoverable. The carrying amount of an asset to be held and used is not recoverable if it exceeds the sum of the undiscounted cash flows expected from the use and eventual disposition of the asset. 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 of 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. Intangible assets are amortized over the period in which the contractual or economic benefits of the intangible assets are expected to be realized.

The Company tests goodwill for impairment annually for each reporting unit in the fourth quarter of the fiscal year and between annual tests, if events occur or circumstances change which suggest that goodwill should be evaluated. Such events or circumstances include significant changes in legal factors and business climate, recent losses at a reporting unit, and industry trends, among other factors. 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.

During the impairment test, 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, goodwill is impaired, and an impairment loss is recognized equal to the excess, limited to the total amount of goodwill allocated to the reporting unit. See also Note 3.

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 fair 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 generally 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 generally the U.S. dollar, except for foreign operations where the functional currency is generally the local currency. 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.

Noncontrolling Interests—Noncontrolling interests represent the equity investments of the minority owners in the Company’s joint ventures and other subsidiary entities that the Company consolidates in its financial statements.

Income Taxes—The Company files a consolidated U.S. federal corporate 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 the nature, frequency, and severity of cumulative financial reporting losses in recent years, the future reversal of existing temporary differences, predictability of future taxable income exclusive of reversing temporary differences of the character necessary to realize the asset, relevant carryforward periods, taxable income in carry-back years if carry-back is permitted under tax law, and prudent and feasible tax planning strategies that would be implemented, if necessary, to protect against the loss of the deferred tax asset that would otherwise expire. 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

2.           New Accounting Pronouncements and Changes in Accounting

In February 2016, the Financial Accounting Standards Board (FASB) issued new accounting guidance which changes accounting requirements for leases. The new guidance requires lessees to recognize the assets and liabilities arising from all leases, including those classified as operating leases under previous accounting guidance, on the balance sheet. It also requires disclosure of key information about leasing arrangements to increase transparency and comparability among organizations. The Company adopted the new guidance beginning October 1, 2019 using the modified retrospective adoption method, which resulted in a downward adjustment to retained earnings of $87.8 million, net of tax. Detailed disclosures regarding the adoption and other required disclosures can be found in Note 11.

In June 2016, the FASB issued a new credit loss standard that changes the impairment model for most financial assets and some other instruments. The new guidance replaces the “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. It also simplifies the accounting model for purchased credit-impaired debt securities and loans. The Company adopted the new guidance effective October 1, 2020 using a modified retrospective approach that resulted in an $8.0 million, net of tax, reduction to retained earnings without restating comparative periods. Additional disclosures regarding the adoption can be found in Note 4.

In February 2018, the FASB issued new accounting guidance which provides entities the option to reclassify certain tax effects from other comprehensive income to retained earnings. The guidance addresses a narrow-scope financial reporting issue related to the tax effects that may become stranded in accumulated other comprehensive income as a result of the enactment of the Tax Cuts and Jobs Act (Tax Act). Under the guidance, an entity may elect to reclassify the income tax effects of the Tax Act on items within accumulated other comprehensive income to retained earnings. The Company has determined that it will not make this election.

In August 2018, the FASB issued new accounting guidance aligning the capitalization of certain implementation costs incurred in a hosting arrangement that is a service contract with previously existing guidance for capitalizing costs incurred to develop internal-use software. The new guidance was effective for the Company’s fiscal year starting October 1, 2020. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

In August 2018, the FASB issued new accounting guidance amending the disclosure requirements for fair value measurements. These improvements require more disclosure for amounts measured at fair value, and specifically unobservable inputs used in fair value measurements. The Company adopted the new guidance starting on October 1, 2020. Adoption of the new guidance did not have a significant impact on the Company’s financial reporting process.

In August 2018, the FASB issued new accounting guidance for the disclosure requirements of defined benefit pension plans. The amended guidance eliminates certain disclosure requirements that were no longer considered to be cost beneficial. The Company expects to adopt the new guidance starting on October 1, 2021 and does not expect adoption of the new guidance will have a significant impact on its financial reporting process.

In March 2020, the Securities and Exchange Commission (SEC) adopted final rules that amend the financial disclosure requirement for guarantors of registered debt securities in Rule 3-10 of Regulation S-X. The new rules amend and streamline the disclosures required by guarantors and issuers of guaranteed securities. Among other things, the new disclosures may be located outside the financial statements. The new rule was effective January 4, 2021, and early adoption is permitted. The Company adopted the new rule on March 31, 2020. Accordingly, the revised condensed consolidating financial information is presented outside of these consolidated financial statements.

Discontinued Operations, Goodwill, and Intangible Assets

3.           Discontinued Operations, Goodwill, and Intangible Assets

During the second quarter of fiscal 2020, the Company completed the sale of its Management Services business to Maverick Purchaser Sub, LLC (Purchaser), an affiliate of American Securities LLC and Lindsay Goldberg LLC. The Company received total cash consideration of $2.28 billion inclusive of the receipt in the third quarter of fiscal 2020 of $122.0 million received in connection with a favorable working capital purchase price adjustment and contingent consideration of approximately $120 million attributable to certain claims related to prior work and engagements. As a result of the sale, the Company recognized a pre-tax gain of $161.9 million. The gain on sale was included in the net loss from discontinued operations in the Consolidated Statements of Operations in fiscal year 2020.

Additionally, in the first quarter of fiscal 2020, management approved a plan to dispose via sale the Company’s self-perform at-risk construction businesses within the next year. These businesses include the Company’s civil infrastructure, power, and oil and gas construction businesses that were previously reported in the Company’s Construction Services segment. After consideration of the relevant facts, the Company concluded the assets and liabilities of its Management Services business and its self-perform at-risk construction businesses met the criteria for classification as held for sale. The Company concluded the actual and proposed disposal activities represented a strategic shift that will have a major effect on the Company’s operations and financial results and qualified for presentation as discontinued operations in accordance with FASB Accounting Standards Codification (ASC) 205-20. Accordingly, the financial results of the Management Services business and the self-perform at-risk construction businesses are presented in the Consolidated Statements of Operations as discontinued operations for all periods presented. Current and non-current assets and liabilities of these businesses not sold as of the balance sheet date are presented in the Consolidated Balance Sheets as assets and liabilities held for sale for both periods presented. Interest expense allocated to discontinued operations represents interest expenses for the discontinued operations’ finance leases and term loans, which were required to be settled upon the sale of the Management Services business.

During the first quarter of fiscal 2021, the Company completed the sale of its power construction business to CriticalPoint Capital, LLC. The Company recorded an additional pre-tax loss on the sale of  $17.3 million in fiscal 2021 related to payments for post-closing working capital adjustments.

The Company also completed the sale of its civil infrastructure construction business to affiliates of Oroco Capital in the second quarter of fiscal 2021. During the second quarter of fiscal 2021, the Company recorded a $32.8 million loss related to the sale of its civil infrastructure construction businesses. Under the terms of the sale agreement, the Company made the required cash payments and delivered the cash and cash equivalents, including cash in consolidated joint ventures, on the balance sheet at closing. As a result, the Company recorded the net cash movement of the sale as a use of cash in the investing section of its statement of cash flows.

During the second quarter of fiscal 2020, the Company identified indicators of impairment for the self-perform at-risk construction business. Specifically, the Company's forecast for its Oil and Gas business decreased significantly from the prior period due primarily to the volatility in global oil prices, which negatively impacted forecasts for future revenues and earnings. As a result, the Company assessed the Oil and Gas business for impairment and determined the fair value of the disposal group was lower than its carrying value. Fair value was estimated using Level 3 inputs, such as forecasted cash flows. Accordingly, the Company recorded impairment losses for that business' goodwill of approximately $83.6 million and intangible assets of approximately $5.7 million. These impairment losses were recorded in net loss from discontinued operations on the Consolidated Statements of Operations in fiscal year 2020.

During the fourth quarter of fiscal 2020, the Company recorded a $247.2 million loss related to the remeasurement of its self-perform at-risk construction businesses to fair value less cost to sell. Fair value was estimated using Level 3 inputs, such as forecasted cash flows, and Level 2 inputs, including bid prices from potential buyers.

Revenue Recognition

Revenue Recognition

4.           Revenue Recognition

The Company follows accounting principles for recognizing revenue upon the transfer of control of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. The Company generally recognizes revenues over time as performance obligations are satisfied. The Company generally measures its progress to completion using an input measure of total costs incurred divided by total costs expected to be incurred. 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 GAAP, are included in the Company’s revenue and cost of revenue. These pass through revenues for the years ended September 30, 2021, 2020 and 2019 were $7.2 billion, $7.1 billion and $7.4 billion, respectively.

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, such as engineering progress, material quantities, the achievement of milestones, penalty provisions, labor productivity and cost estimates. Additionally, the Company is required to make estimates for the amount of consideration to be received, including bonuses, awards, incentive fees, claims, unpriced change orders, penalties, and liquidated damages. Variable consideration is included in the estimate of the transaction price only to the extent that a significant reversal would not be probable. Management continuously monitors factors that may affect the quality of its estimates, and material changes in estimates are disclosed accordingly. Costs attributable to claims are treated as costs of contract performance as incurred.

The following summarizes the Company’s major contract types:

Cost Reimbursable Contracts

Cost reimbursable contracts include cost-plus fixed fee, cost-plus fixed rate, and time-and-materials price contracts. Under cost-plus contracts, the Company charges clients for its costs, including both direct and indirect costs, plus a negotiated fee or rate. The Company recognizes revenue based on actual direct costs incurred and the applicable fixed rate or portion of the fixed fee earned as of the balance sheet date. Under time-and-materials price 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 materials and other direct incidental expenditures incurred in connection with its performance under the contract. The Company may apply a practical expedient to recognize revenue in the amount in which it has the right to invoice if its right to consideration is equal to the value of performance completed to date.

Guaranteed Maximum Price Contracts (GMP)

GMP contracts share many of the same contract provisions as cost-plus and fixed-price contracts. As with cost-plus contracts, clients are provided a disclosure of all the project costs, and a lump sum or percentage fee is separately identified. The Company provides clients with a guaranteed price for the overall project (adjusted for change orders issued by clients) and a schedule including the expected completion date. Cost overruns or costs associated with project delays in completion could generally be the Company’s responsibility. For many of the Company’s commercial or residential GMP contracts, the final price is generally not established until the Company has subcontracted a substantial percentage of the trade contracts with terms consistent with the master contract, and it has negotiated additional contractual limitations, such as waivers of consequential damages as well as aggregate caps on liabilities and liquidated damages. Revenue is recognized for GMP contracts as project costs are incurred relative to total estimated project costs.

Fixed-Price Contracts

Fixed price contracts include both lump-sum and fixed-unit price contracts. Under lump-sum contracts, the Company performs all the work under the contract for a specified fee. Lump-sum contracts are typically subject to price adjustments if the scope of the project changes or unforeseen conditions arise. Under fixed-unit price contracts, the Company performs a 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. Revenue is recognized for fixed-price contracts using the input method measured on a cost-to-cost basis.

The following tables present the Company’s revenues disaggregated by revenue sources:

	Fiscal Year Ended
	September 30,		September 30,		September 30,
	2021		2020		2019
	(in millions)
Cost reimbursable	$	5,319.4	$	5,734.5	$	5,958.2
Guaranteed maximum price		4,582.7		3,896.8		3,962.6
Fixed price		3,438.8		3,608.7		3,721.7
Total revenue	$	13,340.9	$	13,240.0	$	13,642.5

	Fiscal Year Ended
	September 30,		September 30,		September 30,
	2021		2020		2019
	(in millions)
Americas	$	10,228.3	$	10,138.3	$	10,390.8
Europe, Middle East, Africa		1,588.1		1,620.3		1,752.1
Asia Pacific		1,524.5		1,481.4		1,499.6
Total revenue	$	13,340.9	$	13,240.0	$	13,642.5

As of September 30, 2021, the Company had allocated $18.7 billion of transaction price to unsatisfied or partially satisfied performance obligations, of which approximately 55% is expected to be satisfied within the next twelve months.  

Contract liabilities represent amounts billed to clients in excess of revenue recognized to date. The Company recognized revenue of $692.0 million and $592.7 million during the years ended September 30, 2021 and 2020, respectively, that was included in contract liabilities as of September 30, 2020 and 2019, respectively.

The Company’s timing of revenue recognition may not be consistent with its rights to bill and collect cash from its clients. Those rights are generally dependent upon advance billing terms, milestone billings based on the completion of certain phases of work or when services are performed. The Company’s accounts receivable represent amounts billed to clients that have yet to be collected and represent an unconditional right to cash from its clients. Contract assets represent the amount of contract revenue recognized but not yet billed pursuant to contract terms or accounts billed after the balance sheet date. Contract liabilities represent billings as of the balance sheet date, as allowed under the terms of a contract, but not yet recognized as contract revenue pursuant to the Company’s revenue recognition policy.  

Net accounts receivable consisted of the following:

	Fiscal Year Ended
	September 30,		September 30,
	2021		2020
	(in millions)
Billed	$	2,181.1	$	2,467.3
Contract retentions		531.2		531.3
Total accounts receivable—gross		2,712.3		2,998.6
Allowance for doubtful accounts and credit losses		(92.8)		(77.9)
Total accounts receivable—net	$	2,619.5	$	2,920.7

Substantially all contract assets as of September 30, 2021 and September 30, 2020 are expected to be billed and collected within twelve months, except for claims. Significant claims recorded in contract assets and other non-current assets were approximately $140 million and $170 million as of September 30, 2021 and September 30, 2020, respectively. The asset related to the Deactivation, Demolition, and Removal Project retained from the Purchaser discussed in Note 18 is presented in prepaid expense and other current assets from continuing operations in the Consolidated Balance Sheet. Contract retentions represent amounts invoiced to clients where payments have been withheld from progress payments until the contracted work has been completed and approved by the client. These retention agreements vary from project to project and could be outstanding for several months or years.

On October 1, 2020, the Company adopted accounting pronouncements issued by the FASB regarding the changes to the way in which entities estimate credit losses for most financial assets, including accounts receivable and contract assets. The new guidance requires the Company to maintain an allowance for credit losses, which represent the portion of its financial assets that it does not expect to collect over their contractual life. The Company considers a broad range of information to estimate expected credit losses including the related ages of past due balances, projections of credit losses based on historical trends, and collection history and credit quality of its clients. Negative macroeconomic trends or delays in payment of outstanding receivables could result in an increase in the estimated credit losses.

No single client accounted for more than 10% of the Company’s outstanding receivables at September 30, 2021 and September 30, 2020.

The Company sold trade receivables to financial institutions, of which $263.6 million and $166.6 million were outstanding as of September 30, 2021 and September 30, 2020, respectively. The Company does not retain financial or legal obligations for these receivables that would result in material losses. The Company’s ongoing involvement is limited to the remittance of customer payments to the financial institutions with respect to the sold trade receivables.

Joint Ventures and Variable Interest Entities

Joint Ventures and Variable Interest Entities

6.           Joint Ventures and Variable Interest Entities

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

Some of the Company’s joint ventures have no employees and minimal operating expenses. For these joint ventures, the Company’s employees perform work for the joint venture, which is then billed to a third-party customer by the joint venture. These joint ventures function as pass through entities to bill the third-party customer. For consolidated joint ventures of this type, the Company records the entire amount of the services performed and the costs associated with these services, including the services provided by the other joint venture partners, in the Company’s 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 on the consolidation of variable interest entities (VIEs) that requires companies to utilize a qualitative approach to determine whether it is the primary beneficiary of a VIE. The process for identifying the primary beneficiary of a VIE requires consideration of the factors that indicate a party has the power to direct the activities that most significantly impact the joint venture’s economic performance, including powers granted to the joint venture’s program manager, powers contained in the joint venture governing board and, to a certain extent, a company’s economic interest in the joint venture. The Company analyzes its joint ventures and classifies them as either:

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

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

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

Contractually required support provided to the Company’s joint ventures is discussed in Note 18.

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

Pension Benefit Obligations

7.           Pension Benefit Obligations

In the U.S., the Company sponsors various qualified defined benefit pension plans. Benefits under these plans generally are based on the employee’s years of creditable service and compensation; however, all U.S. defined benefit plans are closed to new participants and have frozen accruals.

The Company also sponsors various non-qualified plans in the U.S.; all of these plans are frozen. 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.

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 last three years ended September 30, and reconciliations of the funded status as of September 30 of each year.

Funding requirements for each pension plan are determined based on the local laws of the country where such pension plan resides. In certain countries, the funding requirements are mandatory while in other countries, they are discretionary. The Company currently intends to contribute $24.8 million to the international plans in fiscal 2022. The required minimum contributions for U.S. plans are not significant. In addition, the Company may make discretionary contributions. The Company currently intends to contribute $11.4 million to U.S. plans in fiscal 2022.

Expected long-term rate of return on plan assets	6.80	%	3.95	%	7.30	%	4.03	%	7.00	%	4.43	%

Pension costs are determined using the assumptions as of the beginning of the plan year. 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 2021 and pension plan asset allocation, both U.S. and international, as of September 30, 2021 and 2020:

The Company’s domestic and foreign plans seek a competitive rate of return relative to an appropriate level of risk depending on the funded status and obligations of each plan and typically employ both active and passive investment management strategies. The Company’s risk management practices include diversification across asset classes and investment styles and periodic rebalancing toward asset allocation targets. The target asset allocation selected for each plan reflects a risk/return profile that the Company believes is appropriate relative to each plan’s liability structure and return goals.  

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 6.80% and 3.95% weighted-average long-term rate of return on assets assumption for the fiscal year ended September 30, 2021 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 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, not traded on an active exchange, 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, 2021, there were no material changes to the valuation techniques.

Common collective funds are valued based on net asset value (NAV) per share or unit as a practical expedient as reported by the fund manager, multiplied by the number of shares or units held as of the measurement date. Accordingly, these NAV-based investments have been excluded from the fair value hierarchy. These collective investment funds have minimal redemption notice periods and are redeemable daily at the NAV, less transaction fees, without significant restrictions. There are no significant unfunded commitments related to these investments.

Multiemployer Pension Plans

The Company participates in construction-industry multiemployer pension plans. Generally, the plans provide defined benefits to substantially all employees covered by collective bargaining agreements. Under the Employee Retirement Income Security Act, a contributor to a multiemployer plan is liable, upon termination or withdrawal from a plan, for its proportionate share of a plan’s unfunded vested liability. The Company’s aggregate contributions to these multiemployer plans were $3.7 million and $4.0 million for the years ended September 30, 2021 and 2020, respectively. At September 30, 2021 and 2020, none of the plans in which the Company participates are individually significant to its consolidated financial statements.

Credit Agreement

On February 8, 2021, the Company entered into the 2021 Refinancing Amendment to the Credit Agreement (the “Credit Agreement”), pursuant to which the Company amended and restated its Syndicated Credit Facility Agreement, dated as of October 17, 2014 (as amended prior to February 8, 2021, the “Original Credit Agreement”), between the Company, as borrower, Bank of America, N.A., as administrative agent, and other parties thereto. The Credit Agreement consists of a $1,150,000,000 revolving credit facility (the “Revolving Credit Facility”) and a $246,968,737.50 term loan A facility (the “Term A Facility,” together with the Revolving Credit Facility, the “Credit Facilities”), each of which mature on February 8, 2026. The outstanding loans under the Term A Facility were borrowed in U.S. dollars. Loans under the Revolving Credit Facility may be borrowed, and the Letters of Credit thereunder may be issued, in U.S. dollars or certain foreign currencies. The proceeds of the Revolving Credit Facility may be used from time to time for ongoing working capital and for other general corporate purposes. The proceeds of the Revolving Credit Facility and the Term A Loan facility borrowed on February 8, 2021 were used to refinance the existing revolving credit facility and the existing term loan facility under the Original Credit Agreement and to pay related fees and expenses. The Credit Agreement permits and the Company to designate certain of its subsidiaries as additional co-borrowers from time to time. Currently, there are no co-borrowers under the Credit Facilities.

The applicable interest rate under the Credit Agreement is calculated at a per annum rate equal to, at the Company’s option, (a) the Eurocurrency Rate (as defined in the Credit Agreement) plus an applicable margin (the “LIBOR Applicable Margin”), which is currently at 1.50% or (b) the Base Rate (as defined in the Credit Agreement) plus an applicable margin (the “Base Rate Applicable Margin” and together with the LIBOR Applicable Margin, the “Applicable Margins”), which is currently at 0.50%. The Credit Agreement includes certain environmental, social and governance (ESG) metrics relating to the Company’s CO² emissions and its percentage of employees who identify as women (each, a “Sustainability Metric”). The Applicable Margins and the commitment fees for the revolving credit facility will be adjusted on an annual basis based on the Company’s achievement of preset thresholds for each Sustainability Metric.

Some of the Company’s material subsidiaries (the “Guarantors”) have guaranteed the Company’s obligations of the borrowers under the Credit Agreement, subject to certain exceptions. The borrowers’ obligations under the Credit Agreement are secured by a lien on substantially all of the Company’s assets and its Guarantors’ assets, subject to certain exceptions.

The Credit Agreement contains customary negative covenants that include, among other things, limitations on the ability of the Company and certain of its subsidiaries, subject to certain exceptions, to incur liens and debt, make investments, dispositions, and restricted payments, change the nature of their business, consummate mergers, consolidations and the sale of all or substantially all of their respective assets, taken as a whole, and transact with affiliates. The Company is also required to maintain a consolidated interest coverage ratio of at least 3.00 to 1.00 and a consolidated leverage ratio of less than or equal to 4.00 to 1.00 (subject to certain adjustments in connection with permitted acquisitions), tested on a quarterly basis (the “Financial Covenants”). The Company’s consolidated leverage ratio was 2.4 at September 30, 2021. As of September 30, 2021, the Company was in compliance with the covenants of the Credit Agreement.

The Credit Agreement contains customary affirmative covenants, including, among other things, compliance with applicable law, preservation of existence, maintenance of properties and of insurance, and keeping proper books and records. The Credit Agreement contains customary events of default, including, among other things, nonpayment of principal, interest or fees, cross-defaults to other debt, inaccuracies of representations and warranties failure to perform covenants, events of bankruptcy and insolvency, change of control and unsatisfied judgments, subject in certain cases to notice and cure periods and other exceptions.

On April 13, 2021, the Company entered into Amendment No. 10 to the Credit Agreement, pursuant to which the lenders thereunder provided a secured term “B” credit facility (the “Term B Facility”) to the Company in an aggregate principal amount of $700,000,000. The Term B Facility matures on April 13, 2028. The proceeds of the Term B Facility were used to fund the purchase price, fees and expenses in connection with the Company’s cash tender offer to purchase up to $700,000,000 aggregate purchase price (not including any accrued and unpaid interest) of its outstanding 5.875% Senior Notes due 2024.

The Term B Facility is subject to the same affirmative and negative covenants and events of default as the Term A Facility previously incurred pursuant to the existing Credit Agreement (except that the Financial Covenants in the Credit Agreement do not apply to the Term B Facility). The applicable interest rate for the Term B Facility is calculated at a per annum rate equal to, at the Company’s option, (a) the Eurocurrency Rate (as defined in the Credit Agreement) plus 1.75% or (b) the Base Rate (as defined in the Credit Agreement) plus 0.75%.

On June 25, 2021, the Company entered into Amendment No. 11 to the Credit Agreement, pursuant to which the lenders have provided to the Company an additional $215,000,000 in aggregate principal amount under the Term A Facility. The Company used the net proceeds from the increase in the Term A Facility (together with cash on hand), to (i) redeem all of the Company’s remaining 5.875% Senior Notes due 2024 and (ii) pay fees and expenses related to such redemption.

At September 30, 2021 and September 30, 2020, letters of credit totaled $5.2 million and $19.0 million, respectively, under the Company’s revolving credit facilities. As of September 30, 2021 and September 30, 2020, the Company had $1,144.8 million and $1,331.0 million, respectively, available under its revolving credit facility.

2024 Senior Notes

On October 6, 2014, the Company completed a private placement offering of $800,000,000 aggregate principal amount of the unsecured 5.875% Senior Notes due 2024 (the “2024 Notes”).

On June 25, 2021, the Company redeemed the remaining principal amount of the 2024 Notes outstanding at such time. The redemption price of the 2024 Notes was 115.108% of the remaining outstanding aggregate principal amount, amounting to $217.5 million, plus accrued and unpaid interest. The amounts paid were funded using the proceeds from the additional draw down from the Term A Facility described above and cash on hand. The redemption of the 2024 Notes in the third quarter of fiscal 2021 resulted in a $117.5 million prepayment premium, which was included in interest expense.

2027 Senior Notes

On February 21, 2017, the Company completed a private placement offering of $1,000,000,000 aggregate principal amount of its unsecured 5.125% Senior Notes due 2027 (the “2027 Senior Notes”). On June 30, 2017, the Company completed an exchange offer to exchange the unregistered 2027 Senior Notes for registered notes, as well as related guarantees.

As of September 30, 2021, the estimated fair value of the 2027 Senior Notes was approximately $1,104.5 million. The fair value of the 2027 Senior Notes as of September 30, 2021 was derived by taking the mid-point of the trading prices from an observable market input (Level 2) in the secondary bond market and multiplying it by the outstanding balance of the 2027 Senior Notes. Interest is payable on the 2027 Senior Notes at a rate of 5.125% per annum. Interest on the 2027 Senior Notes is payable semi-annually on March 15 and September 15 of each year, commencing on September 15, 2017. The 2027 Senior Notes will mature on March 15, 2027.

At any time and from time to time prior to December 15, 2026, the Company may redeem all or part of the 2027 Senior Notes, at a redemption price equal to 100% of their principal amount, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest to the redemption date. On or after December 15, 2026, the Company may redeem all or part of the 2027 Notes at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest on the redemption date.

The indenture pursuant to which the 2027 Senior Notes were issued contains customary events of default, including, among other things, payment default, exchange default, failure to provide notices thereunder and provisions related to bankruptcy events. The indenture also contains customary negative covenants.

The Company was in compliance with the covenants relating to the 2027 Senior Notes as of September 30, 2021.

URS Senior Notes

In connection with the 2014 acquisition of the URS Corporation (URS), the Company assumed the URS 5.00% Senior Notes due 2022 (the “2022 URS Senior Notes”).

The remaining $248.5 million principal amount of the 2022 URS Senior Notes were fully redeemed on August 31, 2020 using proceeds from a $248.5 million secured delayed draw term loan facility under the Credit Agreement, at a redemption price that was 106.835% of the principal amount outstanding plus accrued and unpaid interest. The August 31, 2020 redemption resulted in a $17.0 million prepayment premium, which was included in interest expense during the year ended September 30, 2020.

Other Debt and Other Items

Other debt consists primarily of obligations under capital leases and loans, and unsecured credit facilities. The Company’s unsecured credit facilities are primarily used for standby letters of credit issued in connection with general and professional liability insurance programs and for contract performance guarantees. At September 30, 2021 and September 30, 2020, these outstanding standby letters of credit totaled $478.5 million and $510.1 million, respectively. As of September 30, 2021, the Company had $463.6 million available under these unsecured credit facilities.

Effective Interest Rate

The Company’s average effective interest rate on its total debt, including the effects of the interest rate swap agreements and excluding the effects of prepayment premiums included in interest expense, during the years ended September 30, 2021, 2020 and 2019 was 4.4%, 5.3% and 5.1%, respectively.

Interest expense in the consolidated statements of operations included amortization of deferred debt issuance costs for the years ended September 30, 2021, 2020 and 2019 of $10.2 million, $5.4 million and $5.0 million, respectively.

Derivative Financial Instruments and Fair Value Measurements

Derivative Financial Instruments and Fair Value Measurements

9.           Derivative Financial Instruments and Fair Value Measurements

The Company uses 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 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 initially reports any gain on the effective portion of a cash flow hedge as a component of accumulated other comprehensive loss. The gain or loss is subsequently reclassified to interest expense when the interest expense on the variable rate debt is recognized. If the hedged transaction becomes probable of not occurring, any gain or loss related to interest rate swap agreements would be recognized in other income.

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

September 30, 2021
Notional Amount	Notional Amount		Fixed		Effective	Expiration
Currency	(in millions)		Rate		Date	Date
USD		200.0	2.60	%	March 2018	February 2023
USD		400.0	1.349	%	February 2023	March 2028

September 30, 2020
Notional Amount	Notional Amount		Fixed		Effective	Expiration
Currency	(in millions)		Rate		Date	Date
USD		200.0	2.60	%	March 2018	February 2023

Subsequent to the end of the third quarter of fiscal 2021, the Company entered into new interest rate swap agreements with a notional value of $400.0 million to manage the interest rate exposure of its variable rate loans. The new swaps will become effective February 2023 and terminate in March 2028. By entering into the swap agreements, the Company converted a portion of the LIBOR rate-based liability into a fixed rate liability. The Company will pay a fixed rate of 1.349% and receive payment at the prevailing one-month LIBOR.

Other 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 were not material for the years ended September 30, 2021, 2020 and 2019.

Fair Value Measurements

The Company’s non-pension financial assets and liabilities recorded at fair values relate to derivative instruments and were not material at September 30, 2021 or 2020.

See Note 17 for accumulated balances and reporting period activities of derivatives related to reclassifications out of accumulated other comprehensive income or loss for the years ended September 30, 2021, 2020 and 2019. Additionally, there were no material losses recognized in income due to amounts excluded from effectiveness testing from the Company’s interest rate swap agreements.

Concentration of Credit Risk

Concentration of Credit Risk

10.         Concentration of Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of 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 significant 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 4 regarding the Company’s foreign revenues. In order to mitigate credit risk, the Company continually reviews the credit worthiness of its major private clients.

Leases

11.         Leases

On October 1, 2019, the Company adopted FASB ASC 842 on a modified retrospective basis, which amended the accounting standards for leases. Accordingly, the Company applied the new guidance as of the date of adoption with a cumulative-effect adjustment recorded through equity. Prior periods have not been restated as a result of the adoption. Retained earnings decreased $87.8 million due to the adoption, primarily from impairment of the right-of-use assets associated with office building leases.

The Company also applied transition elections that allow it to avoid reassessment of lease definition, classification, or direct costs relating to expired or expiring leases. Adoption of the new lease guidance did not significantly change the Company’s accounting for finance leases, which were previously referred to as capital leases.

The Company and its subsidiaries are lessees in non-cancelable leasing agreements for office buildings and equipment. Substantially all of the Company’s office building leases are operating leases, and its equipment leases are both operating and finance leases. The Company groups lease and non-lease components for its equipment leases into a single lease component but separates lease and non-lease components for its office building leases.

The Company recognizes a right-of-use asset and lease liability for its operating leases at the commencement date equal to the present value of the contractual minimum lease payments over the lease term. The present value is calculated using the rate implicit in the lease, if known, or the Company’s incremental secured borrowing rate. The discount rate used for operating leases is primarily determined based on an analysis the Company’s incremental secured borrowing rate, while the discount rate used for finance leases is primarily determined by the rate specified in the lease.

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. Leases with initial terms shorter than 12 months are not recognized on the balance sheet, and lease expense is recognized on a straight-line basis.

The components of lease expenses are as follows:

Defined Contribution Plans—Substantially all permanent domestic 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; however, the Company does provide an annual Company match in AECOM shares. Employees may generally reallocate their account balances on a daily basis; however, employees classified as insiders are restricted under the Company’s insider trading policy. Compensation expense for the employer contributions related to AECOM stock issued under defined contribution plans during fiscal years ended September 30, 2021, 2020 and 2019 was $26.1 million, $33.7 million, and $32.3 million, respectively.

Stock Incentive Plans—Under the 2020 Stock Incentive Plan, the Company has up to 12.1 million securities remaining available for future issuance as of September 30, 2021. 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 three years in the period ended September 30, 2021, option activity was as follows:

The fair value of the Company’s employee stock option awards is estimated on the date of grant. The expected term of awards granted represents the period of time the awards are expected to be outstanding. The risk-free interest rate is based on U.S. Treasury bond rates with maturities equal to the expected term of the option on the grant date. The Company uses historical data as a basis to estimate the probability of forfeitures. The weighted average grant-date fair value of stock options granted during the year ended September 30, 2020 was $11.30.

The Company grants stock units to employees under its Performance Earnings Program (PEP), whereby units are earned and issued dependent upon meeting established cumulative performance objectives and vest over a three-year service period. Additionally, the Company issues restricted stock units to employees which are earned based on service conditions. The grant date fair value of PEP awards and restricted stock unit awards is that day’s closing market price of the Company’s common stock. The weighted average grant date fair value of PEP awards was $52.76, $42.99, and $27.53 during the years ended September 30, 2021, 2020 and 2019, respectively. The weighted average grant date fair value of restricted stock unit awards was $49.21, $41.90 and $27.73 during the years ended September 30, 2021, 2020 and 2019, respectively. Total compensation expense related to these share-based payments including stock options was $44.7 million, $54.2 million, and $63.8 million during the years ended September 30, 2021, 2020 and 2019, respectively. Unrecognized compensation expense related to total share-based payments outstanding as of September 30, 2021 and 2020 was $45.6 million and $50.0 million, respectively, to be recognized on a straight-line basis over the awards’ respective vesting periods which are generally three years.

During fiscal 2021, the United Kingdom enacted a corporate tax rate increase from 19% to 25% beginning April 2023 requiring deferred tax assets and liabilities to be remeasured. The remeasurement resulted in a $25.9 million tax benefit, which is included in tax rate changes above.

During fiscal 2021, the Company partially settled its U.S. federal audit for fiscal 2015 and 2016 and recorded tax expense of $13.2 million due primarily to changes in tax attributes.

During fiscal 2020, the Company approved a tax planning strategy and restructured certain operations in Canada which resulted in a release of a valuation allowance related to net operating losses and other deferred tax assets of $31.7 million. The Company is now forecasting the utilization of the net operating losses within the foreseeable future. The positive evidence was evaluated against any negative evidence to determine the valuation allowance was no longer needed.

During fiscal 2019, the Company reevaluated a valuation allowance of $38.1 million against foreign tax credits in the U.S. based on new positive evidence related to the issuance of regulations related to The Tax Cuts and Jobs Act (Tax Act) and forecasting the utilization of the foreign tax credits within the foreseeable future. Based on the weighing of all positive and negative evidence the Company determined that a valuation allowance was no longer needed and released the valuation allowance resulting in a tax benefit of $38.1 million.

The Company is currently under tax audit in several jurisdictions including the U.S and believe the outcomes which are reasonably possible within the next twelve months, including lapses in statutes of limitations, could result in adjustments, but will not result in a material change in the liability for uncertain tax positions.

Generally, the Company would reverse its valuation allowance in a particular tax jurisdiction if the positive evidence examined, such as projected and sustainable earnings or a tax-planning strategy that allows for the usage of the deferred tax asset, is sufficient to overcome significant negative evidence, such as large net operating loss carryforwards or a cumulative history of losses in recent years. In the United States, the valued deferred tax assets have a restricted life or use under relevant tax law and, therefore, it is unlikely that the valuation allowance related to these assets will reverse. In addition, the Company is continually investigating tax planning strategies that, if prudent and feasible, may be implemented to realize a deferred tax asset that would otherwise expire unutilized. The identification and internal/external approval (as relevant) of such a prudent and feasible tax planning strategy could cause a reduction in the valuation allowance.

The deferred tax assets (liabilities) are as follows:

As of September 30, 2021, and 2020, the Company has available unused foreign and state net operating loss (NOL) carryforwards of $667.0 million and $710.2 million, respectively, which expire at various dates over the next several years and capital loss carryforwards of $184.1 million and $355.7 million, respectively, which expire in 2025 and 2026; some foreign NOL carryforwards never expire. In addition, as of September 30, 2021, the Company has unused federal and state research and development credits of $75.7 million and $23.4 million, respectively, and other credits of $18.1 million which expire at various dates over the next several years.

As of September 30, 2021, and 2020, gross deferred tax assets were $901.0 million and $956.6 million, respectively. The Company has recorded a valuation allowance of $197.7 million and $217.5 million as of September 30, 2021 and 2020, respectively, primarily related to foreign and state net operating loss carryforwards, capital loss carryforwards, tax credits and other deferred tax assets. The Company has performed an assessment of positive and negative evidence, including the nature, frequency, and severity of cumulative financial reporting losses in recent years, the future reversal of existing temporary differences, predictability of future taxable income exclusive of reversing temporary differences of the character necessary to realize the asset, relevant carryforward periods, taxable income in carry-back years if carry-back is permitted under tax law, and prudent and feasible tax planning strategies that would be implemented, if necessary, to protect against the loss of the deferred tax asset that would otherwise expire. 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 gross deferred tax asset (exclusive of deferred tax liabilities) of $703.3 million will be realized and, as such, no additional valuation allowance has been provided. The net decrease in the valuation allowance of $19.8 million is primarily attributable to a decrease in valuation allowances of $49.5 million related to capital losses, partially offset by increases in valuation allowances of $29.6 million for foreign unbenefitable losses.

Generally, the Company does not provide for U.S. taxes or foreign withholding taxes on gross book-tax differences in its non-U.S. subsidiaries because such basis differences of approximately $1.5 billion are able to and intended to be reinvested indefinitely. If these basis differences were distributed, foreign tax credits could become available under current law to partially or fully reduce the resulting U.S. income tax liability. There may also be additional U.S. or foreign income tax liability upon repatriation, although the calculation of such additional taxes is not practicable.

As of September 30, 2021, and 2020, the Company had a liability for unrecognized tax benefits, including potential interest and penalties, net of related tax benefit, totaling $62.8 million and $65.8 million, respectively. The gross unrecognized tax benefits as of September 30, 2021 and 2020 were $46.4 million and $47.1 million, respectively, excluding interest, penalties, and related tax benefit. Of the $46.4 million, approximately $40.1 million would be included in the effective tax rate if recognized. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows:

	Fiscal Year Ended
	September 30,		September 30,
	2021		2020
	(in millions)
Balance at the beginning of the year	$	47.1	$	55.7
Gross increase in current period’s tax positions		4.3		2.8
Gross increase in prior years’ tax positions		7.5		—
Gross decrease in prior years’ tax positions		—		(7.9)
Decrease due to settlement with tax authorities		(1.3)		(0.5)
Decrease due to lapse of statute of limitations		—		(3.5)
Gross change due to foreign exchange fluctuations		(11.2)		0.5
Balance at the end of the year	$	46.4	$	47.1

The Company classifies interest and penalties related to uncertain tax positions within the income tax expense line in the accompanying consolidated statements of operations. As of September 30, 2021, the accrued interest and penalties were $20.0 million and $3.9 million, respectively, excluding any related income tax benefits. As of September 30, 2020, the accrued interest and penalties were $18.9 million and $2.7 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.

While it is reasonably possible that the total amounts of unrecognized tax benefits could significantly increase or decrease within the next twelve months, an estimate of the range of possible change cannot be made.

Liabilities recorded related to accrued contract losses were not material as of September 30, 2021 and 2020. The Company did not have material revisions to estimates for contracts where revenue is recognized using the percentage-of-completion method during the twelve months ended September 30, 2021. In the first quarter of fiscal 2019, the Company commenced a restructuring plan to improve profitability. The Company incurred restructuring expenses of $48.8 million, including personnel and other costs of $37.8 million and real estate costs of $11.0 million during the year ended September 30, 2021, of which $5.2 million was accrued and unpaid at September 30, 2021. The Company incurred restructuring expenses of $188.3 million, including personnel and other costs of $149.2 million and real estate costs of $39.1 million during the year ended September 30, 2020, of which $56.2 million was accrued and unpaid at September 30, 2020. In connection with this restructuring plan, the Company evaluated its real estate portfolio to better align with the ongoing business. The Company identified certain long-lived assets that were no longer recoverable, and recorded an impairment of $27.4 million in Impairment of long-lived assets, including goodwill during the fourth quarter of fiscal 2019. Fair value of the long-lived assets was determined primarily using Level 3 inputs, such as discounted cash flows.

Commitments and Contingencies

18.         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’s reasonably possible loss disclosures are presented on a gross basis prior to the consideration of insurance recoveries. The Company does not record gain contingencies until they are realized. In the ordinary course of business, the Company may not be aware that it or its affiliates are under investigation and may not be aware of whether or not a known investigation has been concluded.

In the ordinary course of business, the Company may enter into various arrangements providing financial or performance assurance to clients, lenders, or partners. Such arrangements include standby letters of credit, surety bonds, and corporate guarantees to support the creditworthiness or the project execution commitments of its affiliates, partnerships and joint ventures. Performance arrangements typically have various expiration dates ranging from the completion of the project contract and extending beyond contract completion in certain circumstances such as for warranties. The Company may also guarantee that a project, when complete, will achieve specified performance standards. If the project subsequently fails to meet guaranteed performance standards, the Company may incur additional costs, pay liquidated damages or be held responsible for the costs incurred by the client to achieve the required performance standards. The potential payment amount of an outstanding performance arrangement is typically 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) may be required to complete those activities.

At September 30, 2021, the Company was contingently liable in the amount of approximately $483.0 million in issued standby letters of credit and $4.3 billion in issued surety bonds primarily to support project execution.

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 Company’s investment adviser jointly manages and sponsors the AECOM-Canyon Equity Fund, L.P. (the “Fund”), in which the Company indirectly holds an equity interest and has an ongoing capital commitment to fund investments. At September 30, 2021, the Company has capital commitments of $19.3 million to the Fund over the next 7 years.

In addition, in connection with the investment activities of AECOM Capital, the Company provides guarantees of certain contractual obligations, including guarantees for completion of projects, repayment of debt, environmental indemnity obligations and other lender required guarantees.

Department of Energy Deactivation, Demolition, and Removal Project

AECOM Energy and Construction, Inc., an Ohio corporation, a former affiliate of the Company (“Former Affiliate”) executed a cost-reimbursable task order with the Department of Energy (DOE) in 2007 to provide deactivation, demolition and removal services at a New York State project site that, during 2010, experienced contamination and performance issues. In February 2011, the Former Affiliate and the DOE executed a Task Order Modification that changed some cost-reimbursable contract provisions to at-risk. The Task Order Modification, including subsequent amendments, required the DOE to pay all project costs up to $106 million, required the Former Affiliate and the DOE to equally share in all project costs incurred from $106 million to $146 million, and required the Former Affiliate to pay all project costs exceeding $146 million.

Due to unanticipated requirements and permitting delays by federal and state agencies, as well as delays and related ground stabilization activities caused by Hurricane Irene in 2011, the Former Affiliate was required to perform work outside the scope of the Task Order Modification. In December 2014, the Former Affiliate submitted an initial set of claims against the DOE pursuant to the Contracts Disputes Acts seeking recovery of $103 million, including additional fees on changed work scope (the “2014 Claims”). On December 6, 2019, the Former Affiliate submitted a second set of claims against the DOE seeking recovery of an additional $60.4 million, including additional project costs and delays outside the scope of the contract as a result of differing site and ground conditions (the “2019 Claims”). The Former Affiliate also submitted three alternative breach of contract claims to the 2014 and 2019 Claims that may entitle the Former Affiliate to recovery of $148.5 million to $329.4 million. On December 30, 2019, the DOE denied the Former Affiliate’s 2014 Claims. On September 25, 2020, the DOE denied the Former Affiliate’s 2019 Claims. The Company filed an appeal of these decisions on December 20, 2020 in the Court of Federal Claims. Deconstruction, decommissioning and site restoration activities are complete.

On January 31, 2020, the Company completed the sale of its Management Services business to the Purchaser including the Former Affiliate who worked on the DOE project. The Company and the Purchaser agreed that all future DOE project claim recoveries and costs will be split 10% to the Purchaser and 90% to the Company with the Company retaining control of all future strategic legal decisions.

The Company intends to vigorously pursue all claimed amounts but can provide no certainty that the Company will recover 2014 and 2019 Claims submitted against the DOE, or any additional incurred claims or costs, which could have a material adverse effect on the Company’s results of operations.

New York Department of Environmental Conservation

In September 2017, AECOM USA, Inc. was advised by the New York State Department of Environmental Conservation (DEC) of allegations that it committed environmental permit violations pursuant to the New York Environmental Conservation Law (ECL) associated with AECOM USA, Inc.’s oversight of a stream restoration project for Schoharie County which could result in substantial penalties if calculated under the ECL’s maximum civil penalty provisions. AECOM USA, Inc. disputes this claim and intends to continue to defend this matter vigorously; however, AECOM USA, Inc. cannot provide assurances that it will be successful in these efforts. The potential range of loss in excess of any current accrual cannot be reasonably estimated at this time primarily because the matter involves complex and unique environmental and regulatory issues; the project site involves the oversight and involvement of various local, state and federal government agencies; there is substantial uncertainty regarding any alleged damages; and the matter is in its preliminary stages.

Refinery Turnaround Project

A Former Affiliate of the Company entered into an agreement to perform turnaround maintenance services during a planned shutdown at a refinery in Montana in December 2017. The turnaround project was completed in February 2019. Due to circumstances outside of the Company’s Former Affiliate’s control, including client directed changes and delays and the refinery’s condition, the Company’s Former Affiliate performed additional work outside of the original contract over  $90 million and is entitled to payment from the refinery owner of approximately $144 million. In March 2019, the refinery owner sent a letter to the Company’s Former Affiliate alleging it incurred approximately $79 million in damages due to the Company’s Former Affiliate’s project performance. In April 2019, the Company’s Former Affiliate filed and perfected a $132 million construction lien against the refinery for unpaid labor and materials costs. In August 2019, following a subcontractor complaint filed in the Thirteen Judicial District Court of Montana asserting claims against the refinery owner and the Company’s Former Affiliate, the refinery owner crossclaimed against the Company’s Former Affiliate and the subcontractor. In October 2019, following the subcontractor’s dismissal of its claims, the Company’s Former Affiliate removed the matter to federal court and cross claimed against the refinery owner. In December 2019, the refinery owner claimed $93.0 million in damages and offsets against the Company’s Former Affiliate. The parties have agreed on a February 28, 2022 deadline for close of discovery in this matter.

On January 31, 2020, the Company completed the sale of its Management Services business to the Purchaser including the Former Affiliate, however, the Refinery Turnaround Project, including related claims and liabilities, has been retained by the Company.

The Company intends to vigorously prosecute and defend this matter; however, the Company cannot provide assurance that the Company will be successful in these efforts. The resolution of this matter and any potential range of loss cannot be reasonably determined or estimated at this time, primarily because the matter raises complex legal issues that Company is continuing to assess.

19.         Reportable Segments and Geographic Information

During the first quarter of fiscal 2020, the Company reorganized its operating and reporting structure to better align with its ongoing professional services business. This reorganization better reflects the continuing operations of the Company after the sale of its former Management Services reportable segment and planned disposal of its self-perform at-risk construction businesses discussed in Note 3. The businesses that comprised the Company's former Management

Services reportable segment and the civil infrastructure, power and oil and gas construction businesses in the former Construction Services reportable segment were classified as discontinued operations. The former Design and Consulting Services reportable segment and construction management business in the former Construction Services reportable segment were reformed around geographic regions. The Americas segment provides planning, consulting, architectural and engineering design services, and construction management services to commercial and government clients in the United States, Canada, and Latin America, while the International segment provides similar professional services to commercial and government clients in Europe, the Middle East, Africa, and the Asia-Pacific regions.

The Company’s AECOM Capital (ACAP) segment primarily invests in and develops real estate projects. These reportable segments are organized by the differing specialized needs of the respective clients, and how the Company manages its business. The Company has aggregated various operating segments into its reportable segments 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. The change in reportable segments was applied to all periods presented.

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 2021, 2020 and 2019 each contained 52, 53 and 52 weeks, respectively, and ended on October 1, October 2, and September 27, 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 joint ventures in which the Company is the primary beneficiary. All inter-company accounts have been eliminated in consolidation. Also see Note 6 regarding joint ventures and variable interest entities.

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.

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.

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 ten to forty-five years for buildings, three to ten years for furniture and fixtures and three to twelve years for computer systems and equipment. 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 not be recoverable. The carrying amount of an asset to be held and used is not recoverable if it exceeds the sum of the undiscounted cash flows expected from the use and eventual disposition of the asset. 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 of 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. Intangible assets are amortized over the period in which the contractual or economic benefits of the intangible assets are expected to be realized.

The Company tests goodwill for impairment annually for each reporting unit in the fourth quarter of the fiscal year and between annual tests, if events occur or circumstances change which suggest that goodwill should be evaluated. Such events or circumstances include significant changes in legal factors and business climate, recent losses at a reporting unit, and industry trends, among other factors. 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.

During the impairment test, 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, goodwill is impaired, and an impairment loss is recognized equal to the excess, limited to the total amount of goodwill allocated to the reporting unit. See also Note 3.

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 fair 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 generally 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 generally the U.S. dollar, except for foreign operations where the functional currency is generally the local currency. 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.

Noncontrolling Interests

Noncontrolling Interests—Noncontrolling interests represent the equity investments of the minority owners in the Company’s joint ventures and other subsidiary entities that the Company consolidates in its financial statements.

Income Taxes

Income Taxes—The Company files a consolidated U.S. federal corporate 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 the nature, frequency, and severity of cumulative financial reporting losses in recent years, the future reversal of existing temporary differences, predictability of future taxable income exclusive of reversing temporary differences of the character necessary to realize the asset, relevant carryforward periods, taxable income in carry-back years if carry-back is permitted under tax law, and prudent and feasible tax planning strategies that would be implemented, if necessary, to protect against the loss of the deferred tax asset that would otherwise expire. 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.
