2012 ANNUAL REPORT

Dear Shareholders

As we begin 2013, Tetra Tech is in the best financial, technical, and strategic position 

of our 47-year history.  We completed the 2012 fiscal year with all-time record highs in nearly 

every financial metric we track.  We booked record revenue of $2.7 billion, and we exceeded 

$2.0 billion in net revenue for the first time, up 13% from last year.  Our operating income of 

$166 million resulted in record diluted earnings per share of $1.63 and generated operating 

cash flow of $158 million. We ended the year with no net debt and a strong line of credit to 

support future growth and expansion.

For  the  ninth  consecutive  year,  we  were  ranked  #1  in  Water  in  Engineering  News-

Record’s  list  of  top  design  firms,  based  on  revenue  for  water  projects  around  the  world.  

Strengthening our leading position in this market, we were awarded more than $2.0 billion in 

new contracts for water and energy work with the U.S. federal government.  Across the United 

States we worked with our federal and local clients on major watershed restoration and coastal 

protection  programs  in  the  Chesapeake  Bay,  Great  Lakes,  and  the  Gulf  of  Mexico.    For  the 

U.S. Agency for International Development (USAID), we led climate change projects in fragile 

developing regions — including work to develop sustainable fisheries in the Philippines, forest 
management and water supply programs in Liberia, and programs to reduce carbon emissions 

in Mexico.

We continued to expand our water-related services into new markets, including mining 

and oil & gas.  Our global mining revenue grew to more than $320 million in fiscal year 2012,

a  tenfold  growth  from  just  four  years  ago.    In  2012,  our  North  American  shale  gas  and  oil 

sands-related water management and infrastructure work was the fastest growth area in the 

company.   Across the U.S. and Canada we supported our oil & gas clients with  environmental 

permitting, water treatment, modeling, and design engineering services.  We also established 

our presence in the western shale regions of North Dakota and added new pipeline design and 

engineering capabilities with the acquisition of Rooney Engineering.  Our Canadian oil sands 

business  grew  rapidly  to  address  tailings  management,  pipeline  engineering,  and  related 

regional infrastructure needs in Canada.

Tetra Tech today has a more balanced client mix than ever before, evenly distributed 

across  the  U.S  private  sector,  international  markets,  and  U.S.  government  agencies.    Our 

business  mix  is  designed  to  provide  us  with  stability  and  flexibility  in  the  face  of  changing 

economic  conditions  across  the  markets  we  serve.  International  growth  and  access  to 

emerging markets is supported by our recent acquisitions in South America and Australia.  Our 

international expansion strategy has allowed us to establish a permanent base of operations in 

five continents, from which we worked in more than 130 countries over the past year.

Tetra Tech is now comprised of more than 14,000 staff working around the world. Our 

people are proud to make a difference by supporting our clients in water, environment, energy, 

natural resources, and infrastructure services.  We have extraordinary ability and resources to 

address the complex problems of today’s world with Tetra Tech’s clear solutions.  On behalf of 

Tetra Tech, thank you for your continued confidence and support.

Sincerely,

Dan Batrack

Item 1. Business

General

PART I

Tetra Tech, Inc. is a leading provider of consulting, engineering, program management, construction
management, construction and technical services that focuses on addressing fundamental needs for water,
the  environment,  energy,  infrastructure  and  natural  resources.  We  are  a  full-service  company  that  leads
with  science.  We  typically  begin  at  the  earliest  stage  of  a  project  by  identifying  technical  solutions  to
problems and developing execution plans tailored to our clients’ needs and resources. Our solutions may
span the entire life cycle of consulting and engineering projects and include applied science, research and
technology, engineering, design, construction management, construction, operations and maintenance, and
information technology.

We are a global provider of consulting and engineering services, renowned for our leadership in water-
related  services  for  public  and  private  clients.  Engineering  News-Record  (‘‘ENR’’),  the  leading  trade
journal for our industry, has ranked us the number one water services firm for the past nine years, most
recently in its April 19, 2012, ‘‘Top 500 Design Firms’’ issue. In 2012, Tetra Tech was also ranked number
one  in  water  transmission  lines  and  aqueducts,  environmental  management,  and  wind  power.  ENR  also
ranks Tetra Tech among the top 10 firms in numerous other service lines, including environmental science,
engineering/design, sanitary/storm sewers, solid waste, chemical and soil remediation, site assessment and
compliance, hazardous waste, industrial processes, and  manufacturing.

Our commitment to continuous improvement and investment in growth has diversified our client base,
expanded our geographic reach, and increased the breadth and depth of our service offerings to address
existing  and  emerging  markets.  We  currently  have  more  than  13,000  employees  worldwide,  located
primarily in North America.

Mission

Our  mission  is  to  be  the  premier  worldwide  consulting  and  engineering  firm,  focusing  on  water,
natural  resources,  the  environment,  infrastructure  and  energy.  The  following  core  principles  form  the
underpinning of how we work together  to  serve  our clients:

(cid:129) Service. We put our clients first. We listen closely to better understand our clients’ needs and deliver

smart, cost-effective solutions that meet their needs.

4

(cid:129) Value. We  take  on  our  clients’  problems  as  if  they  were  our  own.  We  develop  and  implement

real-world solutions that are innovative, efficient and practical.

(cid:129) Excellence. We bring superior technical capability, disciplined project management, and excellence

in safety and quality to all of our services.

(cid:129) Opportunity. Our people are our number one asset. Our workforce is diverse and includes leading
experts in our fields. Our entrepreneurial nature and commitment to success provide challenges and
opportunities for our employees.

Industry Overview

We are part of the global consulting and engineering industry that serves public and private clients by
addressing  fundamental  needs  for  water,  the  environment,  energy,  infrastructure  and  natural  resources.
Our  industry  provides  clients  with  the  technical  studies,  planning,  engineering,  design,  construction
management and construction services that respond to their needs. The industry’s clients vary in size and
scope  from  small  local  public  agencies  and  private  companies  to  national  governments  and  large  multi-
national  corporations.  These  clients  seek  service  firms  with  high-caliber  technical  expertise,  practical
experience, multi-disciplinary capabilities and the global reach needed to analyze their problems in order
to develop and implement the most appropriate, cost-effective solutions.

Many  government  and  commercial  organizations  face  complex  challenges  due  to  increased  demand
and  competition  for  water  and  natural  resources,  newly  understood  threats  to  human  health  and  the
environment,  aging 
in  emerging  economies,  and
diversification and development of energy resources. As a global company with a local presence in many
areas  around  the  world,  we  provide  the  breadth  of  technical  knowledge  and  capabilities  to  solve  our
clients’ diverse and challenging problems.

infrastructure,  demand  for  new 

infrastructure 

Our water market supports government agencies responsible for managing water supply, wastewater
treatment,  stormwater  and  flood  protection.  Our  water  market  also  supports  private  sector  clients  that
require  water  supply  and  treatment  for  industrial  processes.  We  help  our  clients  develop  water  supplies
and manage water resources, while addressing a wide range of local and national government requirements
and policies. We provide essential support for water and site management needs for resource extraction in
the mining and oil and gas industries. Our water and environmental markets also include both government
and commercial clients that are working to restore contaminated areas and protect uncontaminated areas.
Our  energy  market  consists  of  both  government  and  commercial  clients  that  seek  to  develop  renewable
energy  resources,  identify  energy  efficiency  enhancements,  and  improve  energy  transmission.  Our
infrastructure market includes the design of public and commercial buildings and facilities, including high
efficiency,  low  energy  use  buildings.  Our  natural  resources  market  provides  support  for  the  safe,
sustainable extraction of necessary mineral resources and oil and gas, including the wide range of required
services to meet water, environment, energy and infrastructure-related needs, sometimes in remote regions
of the world.

Increasingly, the consulting and engineering industry is being asked to provide integrated solutions in
a global marketplace. Large firms such as ours can offer fully integrated services, from front-end science
and planning through construction management. Large firms that offer integrated solutions differentiate
themselves from smaller firms that generally offer niche services by providing turn-key solutions intended
to save time and money. As a large company with a history of leading with science, we are ideally suited to
providing  interdisciplinary  solutions  across  our  water  and  related  service  lines.  As  a  provider  of
interdisciplinary services, we have increased our market share  in each of the  last several  years.

Public  policy,  demand  for  resources,  infrastructure  development  challenges  and  natural  forces
constantly  shape  changes  in  our  industry.  Public  concern  over  environmental  issues,  especially  water
quality, has been a driving force behind numerous regulations and changes in public policies and practices.

5

Public  and  private  clients  are  increasingly  focused  on  water  management,  energy  efficiency  and
sustainability.  Fluctuations  in  weather  patterns  and  extreme  events,  such  as  droughts,  hurricanes  or
flooding, are driving concerns over the reliability of water supplies and the need to protect coastal areas
and upgrade water infrastructure. Energy policies, resource limitations and concern about climate change
have  encouraged  the  implementation  of  energy  conservation  measures,  retrofits  to  existing  structures,
upgrades  to  energy  transmission  infrastructure  and  the  development  of  renewable  energy  resources.
Governments are now using international development as a foreign policy tool to help developing nations
to overcome numerous challenges, including  challenges related to water accessibility and human health.

The Tetra Tech Strategy

To  continue  our  successful  growth  and  maintain  a  competitive  position,  we  have  implemented  the

following strategy that is integral to our future success:

Start  with  Science. We  typically  start  with  science  at  the  onset  of  a  project,  building  on  our  staff’s
strong technical and interdisciplinary foundation in natural and physical sciences. This strength allows us to
effectively  evaluate  and  recommend  potential  solutions  to  our  clients’  problems.  We  can  support  our
clients through the entire project life cycle by providing consulting, engineering, construction management,
operations and maintenance, and information technology services. We offer these services individually or
as part of our full-service approach.

Capitalize on our Extensive Technical and Multi-Disciplinary Experience. Since our inception, we have
provided innovative consulting and engineering services, focusing on cost-effective solutions to all aspects
of  water  resource  management.  We  have  been  successful  in  leveraging  this  foundation  of  scientific  and
engineering capabilities into other market areas, including sustainable infrastructure and building design.
Our services are provided by a wide range of professionals, including archaeologists, architects, biologists,
chemical  engineers,  chemists,  civil  engineers,  computer  scientists,  economists,  electrical  engineers,
environmental  engineers,  environmental  scientists,  geologists,  hydrogeologists,  mechanical  engineers,
oceanographers, project managers and toxicologists. Because of the experience that we have gained from
thousands of completed projects, we have relevant expertise to draw from, and are often able to adapt and
apply  proven solutions to our clients’  problems.

Global  Coverage  and  Local  Delivery. We  believe  that  proximity  to  our  clients  is  instrumental  to
understanding  their  needs  and  delivering  comprehensive  services.  We  have  significantly  broadened  our
geographic presence in recent years through strategic acquisitions and internal growth. We currently have
North  American  operations  throughout  the  United  States  and  Canada.  We  have  also  increased  our
international  presence  with  regional  offices  in  Australia,  Europe,  Asia,  South  America,  Africa  and  the
Middle  East.  Our  base  of  operations  in  North  America  and  network  of  international  offices  provide  a
platform  from  which  we  can  respond  to  the  global  need  for  essential  water  and  energy  services,  foster
economic  development,  and  provide  access  to  basic  services.  Over  the  past  year,  we  worked  in  135
countries,  helping  federal  and  local  government  agencies,  the  private  sector  and  development  assistance
entities  address  complex  water,  infrastructure  and  energy  challenges  in  an  environmentally  responsible
manner.

Leverage  Existing  Client  Base. We  believe  that  we  can  effectively  expand  our  service  offerings  to
existing  clients,  resulting  in  more  comprehensive  and  interdisciplinary  projects.  We  have  regularly  been
able  to  secure  design  and  program  management  contracts  after  having  served  clients  on  the  scientific
evaluation and engineering phases of a project. By expanding our role with existing clients, we can address
larger problems and provide integrated solutions. For our global clients, we also focus on expanding from
localized geographic areas to provide  broader national and international support  in multiple  locations.

Identify  and  Expand  into  New  Business  Areas. We  use  our  consulting  services  and  specialized
technical  services  as  entry  points  to  evaluate  adjacent  business  areas.  After  our  consulting  practice  is

6

established in a new business area, we can expand our operations by offering additional technical services.
For example, based on our work in watershed management consulting, we identify adjacent opportunities
and expand into water infrastructure  and  engineering services.

Focus on Large, Complex and Interdisciplinary Projects. We continue to focus on expanding our public
and  private  sector  services  and  bidding  for  complex  projects  that  are  at  the  leading  edge  of  policy  and
technology development. We develop integrated, sustainable solutions by combining our interdisciplinary
capabilities  in  water,  the  environment,  energy,  infrastructure  and  natural  resources.  Our  combination  of
technical  expertise  with  practical  applications  provides  challenging  and  rewarding  opportunities  for  our
employees, thereby enhancing our ability to recruit and  retain  top quality  talent.

Focus on Cash Generation. We take a disciplined approach to monitoring, managing and improving
our  return  on  investment  in  each  of  our  business  areas  through  our  efforts  to  negotiate  appropriate
contract  terms,  manage  our  contract  performance  to  minimize  schedule  delays  and  cost  overruns,  and
promptly bill  and collect accounts receivable.

Actively  Attract,  Recruit  and  Retain  Strategic  Hires. We  focus  on  attracting  and  retaining  top-quality
individuals  who  provide  technical  skills,  innovative  thinking,  teamwork  and  dedication  to  maintaining
long-term  client  relationships.  Our  full-service  capabilities,  internal  coordination  and  networking
programs, entrepreneurial environment, focus on technical excellence and global project portfolio help to
attract and retain highly qualified individuals who support  our long-term growth.

In
Develop  and  Maintain  Strategic  Partnerships  with  Small  Business  Companies  and  Communities.
working  with  suppliers,  we  are  committed  to  being  an  excellent  partner  and  mentor,  consistent  with  our
desire to lead with science and develop approaches to best serve our global clients. When combined with
our  considerable  capabilities  and  expertise,  value-added  partnerships  with  external  companies  and
suppliers  can  enhance  the  services  we  provide  to  our  clients.  We  have  established  a  Small  Business  and
Partnerships  Council  to  identify  and  promote  the  most  successful  partnerships  and  to  coordinate  best
practices across our company.

Invest  in  Strategic  Acquisitions. We  believe  that  strategic  acquisitions  will  allow  us  to  continue  our
growth in selected business areas, broaden our service offerings and extend our geographic presence. We
intend to continue to acquire companies that will help establish our position in certain emerging business
areas  or  further  strengthen  our  position  in  our  more  established  businesses.  Our  effective  integration  of
acquired companies can continue to enhance our ability to compete  technically  and geographically.

In  the  first  quarter  of  fiscal  2012,  we  implemented  organizational  changes  that  resulted  in  a
realignment of certain operating activities in our reportable segments. This realignment resulted from the

7

organic growth of new activities in a component of an existing reportable segment due to changing business
conditions.  The  changes  were  intended  to  improve  organizational  effectiveness  and  efficiency  by  better
aligning operations with similar characteristics such as client types, project types, required resources and
financial metrics. Prior year amounts have been reclassified to conform to the current year presentation.

In  the  fourth  quarter  of  fiscal  2012,  we  initiated  a  reorganization  of  our  operations,  including  the

Contracts

Our  services  are  performed  under  three  principal  types  of  contracts  with  our  clients:  fixed-price,
time-and-materials, and cost-plus. The following table presents the percentage of our revenue by contract
type:

Our clients select the type of contract we enter into for a particular engagement. Under a fixed-price
contract, the client agrees to pay a specified price for our performance of the entire contract or a specified
portion  of  the  contract.  Some  fixed-price  contracts  can  include  date-certain  and/or  performance
losses  from
obligations.  Fixed-price  contracts  carry  certain 
underestimating  costs,  delays  in  project  completion,  problems  with  new  technologies,  price  increases  for
materials,  and  economic  and  other  changes  that  may  occur  over  the  contract  period.  Consequently,  the
profitability of fixed-price contracts may vary substantially. Under our time-and-materials contracts, we are
paid for labor at negotiated hourly billing rates and for other expenses. Profitability on these contracts is
driven  by  billable  headcount  and  cost  control.  Many  of  our  time-and-materials  contracts  are  subject  to
maximum  contract  values  and,  accordingly,  revenue  related  to  these  contracts  is  recognized  as  if  these
contracts were fixed-price contracts. Under our cost-plus contracts, we are reimbursed for allowable costs
and  fees,  which  may  be  fixed  or  performance-based.  If  our  costs  exceed  the  contract  ceiling  or  are  not
allowable, we may not be able to obtain full reimbursement. Further, the amount of the fee received for a

including  risks  of 

inherent  risks, 

18

cost-plus  award  fee  contract  partially  depends  upon  the  client’s  discretionary  periodic  assessment  of  our
performance on that contract.

Some contracts with the U.S. federal government are subject to annual funding approval. U.S. federal
government  agencies  may  impose  spending  restrictions  that  limit  the  continued  funding  of  our  existing
contracts  and  may  limit  our  ability  to  obtain  additional  contracts.  These  limitations,  if  significant,  could
have a material adverse effect on us. All contracts with the U.S. federal government may be terminated by
the government at any time, with or without  cause.

U.S. federal government agencies have formal policies against continuing or awarding contracts that
would  create  actual  or  potential  conflicts  of  interest  with  other  activities  of  a  contractor.  These  policies
may prevent us from bidding for or performing government contracts resulting from or related to certain
work  we  have  performed.  In  addition,  services  performed  for  a  commercial  or  government  sector  client
may create conflicts of interest that preclude or limit our ability to obtain work for a private organization.
We  attempt  to  identify  actual  or  potential  conflicts  of  interest  and  to  minimize  the  possibility  that  such
conflicts could affect our work under current contracts or our ability to compete for future contracts. We
have, on occasion, declined to bid on  a project because of an existing or potential conflict of interest.

Some of our operating units have contracts with the U.S. federal government that are subject to audit
by  the  government,  primarily  by  the  Defense  Contract  Audit  Agency  (‘‘DCAA’’).  The  DCAA  generally
seeks  to  (i)  identify  and  evaluate  all  activities  that  contribute  to,  or  have  an  impact  on,  proposed  or
incurred  costs  of  government  contracts;  (ii)  evaluate  a  contractor’s  policies,  procedures,  controls  and
performance;  and  (iii)  prevent  or  avoid  wasteful,  careless  and  inefficient  production  or  service.  To
accomplish  this,  the  DCAA  examines  our  internal  control  systems,  management  policies  and  financial
capability;  evaluates  the  accuracy,  reliability  and  reasonableness  of  our  cost  representations  and  records;
and assesses our compliance with Cost Accounting Standards (‘‘CAS’’) and defective-pricing clauses found
within  the  Federal  Acquisition  Regulation  (‘‘FAR’’).  The  DCAA  also  performs  an  annual  review  of  our
overhead rates and assists in the establishment of our final rates. This review focuses on the allowability of
cost  items  and  the  applicability  of  CAS.  The  DCAA  also  audits  cost-based  contracts,  including  the
close-out of those contracts.

The  DCAA  reviews  all  types  of  U.S.  federal  government  proposals,  including  those  of  award,
administration, modification and re-pricing. The DCAA considers our cost accounting system, estimating
methods  and  procedures,  and  specific  proposal  requirements.  Operational  audits  are  also  performed  by
the  DCAA.  A  review  of  our  operations  at  every  major  organizational  level  is  conducted  during  the
proposal review period. During the course of its audit, the U.S. federal government may disallow costs if it
determines  that  we  accounted  for  such  costs  in  a  manner  inconsistent  with  CAS.  Under  a  government
contract, only those costs that are reasonable, allocable and allowable are recoverable. A disallowance of
costs by the U.S. federal government  could  have a material adverse  effect on our financial results.

In accordance with our corporate policies, we maintain controls to minimize any occurrence of fraud
or other  unlawful activities that could result in severe legal remedies, including the payment of damages
and/or penalties, criminal and civil sanctions, and debarment. In addition, we maintain preventative audit
programs and mitigation measures to ensure that appropriate control systems are in  place.

We provide our services under contracts, purchase orders or retainer letters. Our policy provides that
all contracts must be in writing. We bill our clients in accordance with the contract terms and periodically
based  on  costs  incurred,  on  either  an  hourly-fee  basis  or  on  a  percentage-of-completion  basis,  as  the
project progresses. Most of our agreements permit our clients to terminate the agreements without cause
upon payment of fees and expenses through the date of the termination. Generally, our contracts do not
require that we provide performance bonds. If required, a performance bond, issued by a surety company,
guarantees  a  contractor’s  performance  under  the  contract.  If  the  contractor  defaults  under  the  contract,
the surety will, at its discretion, complete the job or pay the client the amount of the bond. If the contractor
does  not  have  a  performance  bond  and  defaults  in  the  performance  of  a  contract,  the  contractor  is

19

responsible  for  all  damages  resulting  from  the  breach  of  contract.  These  damages  include  the  cost  of
completion, together with possible consequential damages  such as lost  profits.

Marketing and Business Development

Our  corporate  management  team  establishes  the  scope  and  range  of  services  we  provide  and  our
overall  business  strategy.  Our  annual  strategic  planning  defines  and  guides  our  investment  in  marketing
and  business  development  toward  priority  programs  and  growth  markets.  Our  centralized  business
development  support  group  develops  corporate  marketing  materials,  conducts  market  research,  and
manages  promotional  and  professional  activities,  including  appearances  at  trade  shows,  direct  mailings,
advertising and public relations.

Business development activities are implemented by our technical and professional management staff
throughout the company. We believe that these personnel have the best understanding of a client’s needs
and  the  effect  of  local  or  client-specific  issues,  laws  and  regulations  and  procurement  procedures.  Our
professional staff members hold frequent meetings with existing and potential clients; give presentations to
civic  and  professional  organizations;  and  present  seminars  on  current  technical  topics.  Essential  to  the
effective development of business is each staff member’s access to all of our service offerings through our
internal  technical  and  geographic  networks.  Our  strong  internal  networking  programs  help  our
professional  staff  members  to  pursue  new  opportunities  for  both  for  existing  and  new  clients.  These
networks  also  facilitate  our  ability  to  provide  services  throughout  the  project  life  cycle  from  the  early
studies through to construction management and operations. Our information technology systems provide
the  support  for  a  variety  of  data  needs  including  skills  search  tools,  business  development  tracking,  and
collaboration.

For  our  major  focus  areas,  consistent  with  our  strategic  plan,  we  have  established  company-wide
growth  initiatives  that  reinforce  internal  coordination,  track  the  development  of  new  programs,  identify
and  coordinate  collective  resources  for  major  bids,  and  help  us  build  interdisciplinary  teams  for  major
pursuits.  Our  growth  initiatives  provide  a  forum  for  cross-sector  collaboration  and  the  development  of
interdisciplinary solutions. We continuously identify new markets that are consistent with our strategic plan
and  service  offerings,  and  we  leverage  our  full-service  capabilities  and  internal  coordination  structure  to
develop  and  implement  strategies  to  research,  anticipate  and  position  for  future  procurements  and
emerging programs.

Sustainability Program

Our Sustainability Program allows us to encourage, coordinate and report on actions to minimize our
collective impacts on the environment. Our Sustainability Program has three primary pillars: Projects – the
solutions we provide for our clients; Procurement – our procurement and subcontracting approaches; and
Processes  –  the  internal  policies  and  processes  that  promote  sustainable  practices,  reduce  costs  and
minimize  environmental  impacts.  We  have  established  a  clear  set  of  metrics  to  evaluate  our  progress
toward  our  sustainability  goals.  We  continuously  implement  sustainability-related  policies  and  practices,
and we assess the results of our efforts in  order to improve upon them in the future.

Our  Sustainability  Program  is  led  by  our  Chief  Sustainability  Officer,  who  has  been  appointed  by
executive  management  and  is  supported  by  other  key  corporate  and  operations  representatives  via  our
sustainability  council.  Our  executive  management  team  reviews  and  approves  the  Sustainability  Program
and evaluates our progress in achieving the goals and objectives outlined in our plan. We publish an annual
sustainability report that documents our  progress.

Acquisitions

We  continuously  evaluate  the  marketplace  for  strategic  acquisition  opportunities.  Due  to  our
reputation,  size,  financial  resources,  geographic  presence  and  range  of  services,  we  have  numerous

20

opportunities  to  acquire  privately  and  publicly  held  companies  or  selected  portions  of  such  companies.
During our evaluation, we examine the effect an acquisition may have on our long-range business strategy
and  results  of  operations.  Generally,  we  proceed  with  an  acquisition  if  we  believe  that  it  would  have  a
positive  effect  on  future  operations  and  could  strategically  expand  our  service  offerings.  Successful
integration and implementation are essential to achieving favorable results. Accordingly, no assurance can
be given that any acquisition will provide  accretive  results.

Our strategy is to position ourselves to address existing and emerging markets. We view acquisitions as
a  key  component  of  our  growth  strategy,  and  we  intend  to  use  cash,  debt  or  securities,  as  we  deem
appropriate, to fund acquisitions. We may acquire other businesses that we believe are synergistic and will
ultimately  increase  our  revenue  and  net  income,  strengthen  our  ability  to  achieve  our  strategic  goals,
provide  critical  mass  with  existing  clients  and  further  expand  our  lines  of  service.  We  typically  pay  a
purchase price that results in the recognition of goodwill, generally representing the intangible value of a
successful  business  with  an  assembled  workforce  specialized  in  our  areas  of  interest.  Acquisitions  are
inherently risky, and no assurance can be given that our previous or future acquisitions will be successful or
will  not  have  a  material  adverse  effect  on  our  financial  position,  results  of  operations  or  cash  flow.  All
acquisitions require the approval of our Board of Directors, and those in excess of a certain size require
the approval of our lenders.

For  detailed  information  regarding  acquisitions,  see  Note  4,  ‘‘Mergers  and  Acquisitions’’  of  the

‘‘Notes to Consolidated Financial Statements’’ included in Item 8.

Competition

The market for our services is generally competitive. We often compete with many other firms ranging

from small regional firms to large international firms.

We perform a broad spectrum of consulting, engineering and technical services across our reportable
segments.  Our  client  base  includes  U.S.  federal  government  agencies  such  as  the  DoD,  USAID,  DOE,
EPA  and  FAA;  U.S.  state  and  local  government  agencies;  provincial  governments  in  Canada;  the  U.S.
commercial  sector,  which  consists  primarily  of  large  industrial  companies  and  utilities;  and  our
international commercial clients, which are predominately located in Canada and include primarily mining
and oil companies. Our competition varies and is a function of the business areas in which, and the client
sectors  for  which,  we  perform  our  services.  The  number  of  competitors  for  any  procurement  can  vary
widely, depending upon technical qualifications, the relative value of the project, geographic location, the
financial  terms  and  risks  associated  with  the  work,  and  any  restrictions  placed  upon  competition  by  the
client.  Historically,  clients  have  chosen  among  competing  firms  by  weighing  the  quality,  innovation  and
timeliness of the firm’s service versus its cost to determine which firm offers the best value. When less work
becomes available in a given market, price  becomes an  increasingly important factor.

We believe that our principal competitors include the following firms, in alphabetical order: AECOM
Technology  Corporation;  AMEC  PLC;  Arcadis  NV;  Black  &  Veatch  Corporation;  Brown  &  Caldwell;
CDM Smith, Inc.; CH2M Hill Companies Ltd.; Chemonics International Inc.; Dessau Inc.; Foster Wheeler
AG;  GENIVAR  Inc.;  GHD;  ICF  International,  Inc.;  Jacobs  Engineering  Group  Inc.;  Michael  Baker
Corporation; MWH Global, Inc.; Science Applications International Corporation; The Shaw Group Inc.;
Sinclair  Knight  Merz  Pty  Ltd.;  SNC-Lavalin  Group  Inc.;  Stantec  Inc.;  TRC  Companies,  Inc.;  URS
Corporation; Weston Solutions, Inc.; and Willbros Group, Inc.

Backlog

We  include  in  our  backlog  only  those  contracts  for  which  funding  has  been  provided  and  work
authorization has been received. We estimate that approximately 80% of our backlog at the end of fiscal
2012  will  be  recognized  as  revenue  in  fiscal  2013,  as  work  is  being  performed.  However,  we  cannot
guarantee that the revenue projected in our backlog will be realized or, if realized, will result in profits. In

21

addition,  project  cancellations  or  scope  adjustments  may  occur  with  respect  to  contracts  reflected  in  our
backlog.  For  example,  certain  of  our  contracts  with  the  U.S.  federal  government  and  other  clients  are
terminable at the discretion of the client, with or without cause. These types of backlog reductions could
adversely  affect  our  revenue  and  margins.  Accordingly,  our  backlog  as  of  any  particular  date  is  an
uncertain indicator of our future earnings.

At fiscal 2012 year-end, our backlog was $2.1 billion, an increase of $189.3 million, or 9.7%, compared
to last year-end. Our backlog growth was driven by demand for our energy and infrastructure services in
the commercial and U.S. state and local government markets. Further, the growth was due to new orders
from our international clients, particularly for our water, environmental and infrastructure design services
in the mining and other commodity-driven  markets.

Regulations

We  engage  in  various  service  activities  that  are  subject  to  government  oversight,  including
environmental  laws  and  regulations,  general  government  procurement  laws  and  regulations,  and  other
regulations and requirements imposed by specific government agencies with which  we conduct business.

Environmental. A  significant  portion  of  our  business 

involves  planning,  design,  program
management  and  construction  management  of  pollution  control  facilities,  as  well  as  assessment  and
management  of  remediation  activities  at  hazardous  waste  or  U.S.  Superfund  sites  and  military  bases.  In
addition,  we  contract  with  U.S.  federal  government  entities  to  destroy  hazardous  materials,  including
weapons stockpiles. These activities require us to manage, handle, remove, treat, transport and dispose of
toxic or hazardous substances.

Some environmental laws, such as the Superfund law and similar state and local statutes, can impose
liability for the entire cost of clean-up for contaminated facilities or sites upon present and former owners
and operators, as well as generators, transporters and persons arranging for the treatment or disposal of
such  substances.  In  addition,  while  we  strive  to  handle  hazardous  and  toxic  substances  with  care  and  in
accordance  with  safe  methods,  the  possibility  of  accidents,  leaks,  spills  and  the  events  of  force  majeure
always  exist.  Humans  exposed  to  these  materials,  including  workers  or  subcontractors  engaged  in  the
transportation  and  disposal  of  hazardous  materials  and  persons  in  affected  areas,  may  be  injured  or
become  ill,  resulting  in  lawsuits  that  expose  us  to  liability  that  may  result  in  substantial  damage  awards.
Liabilities  for  contamination  or  human  exposure  to  hazardous  or  toxic  materials,  or  a  failure  to  comply
with applicable regulations, could result in substantial costs, including clean-up costs, fines, civil or criminal
sanctions, third party claims for property damage or personal injury, or cessation of remediation activities.

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

Government  Procurement. The  services  we  provide  to  the  U.S.  federal  government  are  subject  to

FAR and other rules and regulations  applicable to government contracts. These rules and  regulations:

(cid:129) require  certification  and  disclosure  of  all  cost  and  pricing  data  in  connection  with  the  contract

negotiations under certain contract types;

(cid:129) impose accounting rules that define allowable and unallowable costs and otherwise govern our right

to reimbursement under certain cost-based government contracts; and

(cid:129) restrict  the  use  and  dissemination  of  information  classified  for  national  security  purposes  and  the

exportation of certain products and technical  data.

22

In  addition,  services  provided  to  the  DoD  are  monitored  by  the  Defense  Contract  Management
Agency and audited by the DCAA. Our government clients can also terminate any of their contracts, and
many of our government contracts are subject to renewal or extension annually. Further, the services we
provide to state and local government  clients are  subject to various government rules and regulations.

Seasonality

We experience seasonal trends in our business. Our revenue and operating income are typically lower
in the first half of our fiscal year, primarily due to the Thanksgiving, Christmas and New Year’s holidays.
Many of our clients’ employees, as well as our own employees, do not work during these holidays. Further,
seasonal  inclement  weather  conditions  cause  some  of  our  offices  to  close  temporarily  or  hamper  our
project field work, particularly in the ECS and RCM segments. These occurrences result in fewer billable
hours worked on projects and, correspondingly, less revenue recognized. Our revenue is typically higher in
the second half of the fiscal year due to favorable weather conditions during spring and summer months
that  may  result  in  higher  billable  hours.  In  addition,  our  revenue  is  typically  higher  in  the  fourth  fiscal
quarter due to the U.S. federal government’s fiscal year-end spending.

Potential Liability and Insurance

Our  business  activities  could  expose  us  to  potential  liability  under  various  environmental  laws  and
under  workplace  health  and  safety  regulations.  In  addition,  we  occasionally  assume  liability  by  contract
under indemnification agreements. We  cannot predict the magnitude of such potential liabilities.

We  maintain  a  comprehensive  general  liability  policy  with  an  umbrella  policy  that  covers  losses
beyond  the  general  liability  limits.  We  also  maintain  professional  errors  and  omissions  liability  and
contractor’s pollution liability insurance policies. We believe that both policies provide adequate coverage
for  our  business.  When  we  perform  higher-risk  work,  such  as  fixed-price  remediation,  we  obtain  the
necessary types of insurance coverage for  such activities,  as is  typically  required by our clients.

We obtain insurance coverage through a broker that is experienced in the professional liability field.
The broker and our risk manager regularly review the adequacy of our insurance coverage. Because there
are  various  exclusions  and  retentions  under  our  policies,  or  an  insurance  carrier  may  become  insolvent,
there can be no assurance that all potential liabilities will be covered by our insurance policies or paid by
our  carrier.

We  evaluate  the  risk  associated  with  claims.  If  we  determine  that  a  loss  is  probable  and  reasonably
estimable, we establish an appropriate reserve. A reserve is not established if we determine that a claim has
no merit or is not probable or reasonably estimable. Our historic levels of insurance coverage and reserves
have  been  adequate.  However,  partially  or  completely  uninsured  claims,  if  successful  and  of  significant
magnitude, could have a material adverse  effect on our business.

Employees

At  fiscal  2012  year-end,  we  had  more  than  13,000  employees  including  part-time  workers.  A  large
percentage  of  our  employees  have  technical  and  professional  backgrounds  and  undergraduate  and/or
advanced degrees, including the employees of recently acquired companies. Our professional staff includes
archaeologists,  architects,  biologists,  chemical  engineers,  chemists,  civil  engineers,  computer  scientists,
economists,  electrical  engineers,  environmental  engineers,  environmental  scientists,  geologists,
toxicologists.
hydrogeologists,  mechanical  engineers,  oceanographers,  project  managers  and 
Approximately  500  employees  are  represented  by  labor  unions  pursuant  to  collective  bargaining
agreements.  We  often  employ  union  workers  on  a  project-specific  basis.  We  consider  the  current
relationships with our employees including those represented by unions, to be favorable. We are not aware
of  any  employment  circumstances  that  are  likely  to  disrupt  work  at  any  of  our  facilities.  See  Part  I,

23

Item 1A, ‘‘Risk Factors’’ for a discussion of the risks related to the loss of key personnel or our inability to
attract and retain qualified personnel.

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.

Our operating results may be adversely impacted by worldwide political and economic uncertainties and
specific conditions in the markets we  address.

General  worldwide  economic  conditions  have  experienced  a  downturn  due  to  the  reduction  of
available  credit,  slower  economic  activity,  concerns  about  inflation  and  deflation,  increased  energy  and
commodity costs, decreased consumer confidence and capital spending, adverse business conditions, and,
in the United States, the negative impact on economic growth resulting from the combination of federal
income  tax  increases  and  government  spending  restrictions  (described  in  more  detail  below)  potentially
occurring at the end of calendar year 2012 (commonly referred to as the ‘‘fiscal cliff.’’). These conditions
make it extremely difficult for our clients and our vendors to accurately forecast and plan future business
activities and could cause businesses to slow spending on services, and they have also made it very difficult
for  us  to  predict  the  short-term  and  long-term  impacts  on  our  business.  We  cannot  predict  the  timing,
strength  or  duration  of  any  economic  slowdown  or  subsequent  economic  recovery  worldwide  or  in  our
industry. If the economy or markets in which we operate deteriorate from the level experienced in fiscal
2012, our business, financial condition and results of operations may be materially and adversely affected.

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

On August 2, 2011, the Budget Control Act of 2011 (the ‘‘Budget Control Act’’) was enacted, which
could  impose  an  estimated  $1.2  trillion  in  future  federal  spending  cuts  if  budget  deficit  targets  are  not
achieved. If the federal government does not meet the Budget Control Act targets or does not otherwise
delay  or  change  this  legislation,  then  automatic  across-the-board  budget  cuts,  or  sequestrations,  will  be
mandated  across  the  federal  budget  in  fiscal  year  2013.  Any  significant  reduction  in  federal  government
spending could reduce demand for our services, cancel or delay federal projects, and result in the closure
of federal facilities and significant personnel reductions, which could have a material adverse effect on our
results of operation and financial condition.

Our annual revenue, expenses and operating results may fluctuate significantly, which may adversely affect
our stock price.

Our annual revenue, expenses and operating results may fluctuate significantly because of numerous
factors, some of which may contribute to more pronounced fluctuations in an uncertain global economic
environment. These factors include:

(cid:129) general economic or political conditions;

(cid:129) unanticipated  changes  in  contract  performance  that  may  affect  profitability,  particularly  with

contracts that are fixed-price or have funding limits;

(cid:129) contract  negotiations  on  change  orders,  requests  for  equitable  adjustment,  and  collections  of

related billed and unbilled accounts receivable;

(cid:129) seasonality of the spending cycle of our public sector clients, notably the U.S. federal government,

the spending patterns of our commercial sector  clients, and weather  conditions;

(cid:129) budget constraints experienced by  our U.S. federal,  state and  local  government clients;

30

(cid:129) integration of acquired companies;

(cid:129) changes in contingent consideration related  to  acquisition  earn-outs;

(cid:129) divestiture or discontinuance of operating units;

(cid:129) employee hiring, utilization and turnover rates;

(cid:129) loss of key employees;

(cid:129) the number and significance of client contracts commenced and completed during a  quarter;

(cid:129) creditworthiness and solvency of clients;

(cid:129) the ability of our clients to terminate contracts without  penalties;

(cid:129) delays incurred in connection with  a contract;

(cid:129) the size, scope and payment terms of  contracts;

(cid:129) the timing of expenses incurred for corporate  initiatives;

(cid:129) reductions in the prices of services offered  by  our competitors;

(cid:129) threatened or pending litigation;

(cid:129) legislative and regulatory enforcement  policy changes  that  may affect demand for  our  services;

(cid:129) the impairment of goodwill or identifiable intangible  assets;

(cid:129) the fluctuation of a foreign currency exchange rate;

(cid:129) stock-based compensation expense;

(cid:129) actual  events,  circumstances,  outcomes  and  amounts  differing  from  judgments,  assumptions  and
estimates used in determining the value of certain assets (including the amounts of related valuation
allowances), liabilities and other items reflected in  our consolidated  financial  statements;

(cid:129) how well we execute our strategy and operating plans;

(cid:129) changes in tax laws or regulations or  accounting rules;

(cid:129) results of income tax examinations;

(cid:129) the  timing  of  announcements  in  the  public  markets  regarding  new  services  or  potential  problems
with the performance of services by us or our competitors, or any other material announcements;

(cid:129) speculation  in  the  media  and  analyst  community,  changes  in  recommendations  or  earnings
estimates  by  financial  analysts,  changes  in  investors’  or  analysts’  valuation  measures  for  our  stock
and market trends unrelated to our stock;  and

(cid:129) continued volatility in the financial markets.

As  a  consequence,  operating  results  for  a  particular  future  period  are  difficult  to  predict  and,
therefore, prior results are not necessarily indicative of results to be expected in future periods. Any of the
foregoing factors, or any other factors discussed elsewhere herein, could have a material adverse effect on
our  business, results of operations and financial condition that  could adversely  affect our stock price.

31

Demand  from  our  U.S.  state  and  local  government  clients  and  U.S.  commercial  clients  is  cyclical  and
vulnerable to economic downturns. If economic growth slows, government fiscal conditions worsen, or client
spending declines further, then our revenue, profits  and our  financial condition may deteriorate.

Demand for services from our U.S. state and local government clients and U.S. commercial clients is
cyclical and vulnerable to economic downturns, which may result in clients delaying, curtailing or canceling
proposed  and  existing  projects.  Our  business  traditionally  lags  the  overall  recovery  in  the  economy;
therefore,  our  business  may  not  recover  immediately  when  the  economy  improves.  If  economic  growth
slows, U.S. state or local government fiscal conditions worsen, or client spending declines further, then our
revenue,  profits  and  overall  financial  condition  may  deteriorate.  Our  U.S.  state  and  local  government
clients may face budget deficits that prohibit them from funding new or existing projects. In addition, our
existing and potential clients may either postpone entering into new contracts or request price concessions.
Difficult financing and economic conditions may cause some of our clients to demand better pricing terms
or delay payments for services we perform, thereby increasing the average number of days our receivables
are  outstanding  and  the  potential  of  increased  credit  losses  of  uncollectible  invoices.  Further,  these
conditions  may  result  in  the  inability  of  some  of  our  clients  to  pay  us  for  services  that  we  have  already
performed. If we are not able to reduce our costs quickly enough to respond to the revenue decline from
these clients, our operating results may be adversely affected. Accordingly, these factors affect our ability
to forecast our future revenue and earnings from business areas that may be adversely impacted by market
conditions.

Our revenue from U.S. commercial clients is significant, and the credit risks associated with certain of these
clients could adversely affect our operating  results.

In fiscal 2012, we generated 26.5% of our revenue from U.S. commercial clients. Due to continuing
weakness in general economic conditions, our U.S. commercial business may be at risk as we rely upon the
financial  stability  and  creditworthiness  of  our  clients.  To  the  extent  the  credit  quality  of  these  clients
deteriorates  or  these  clients  seek  bankruptcy  protection,  our  ability  to  collect  our  receivables,  and
ultimately our operating results, may  be  adversely affected.

We derive a substantial amount of our revenue from U.S. federal, state and local government agencies, and
any disruption in government funding or in our relationship with those agencies could adversely affect our
business.

In  fiscal  2012,  we  generated  49.0%  of  our  revenue  from  contracts  with  U.S.  federal,  state  and  local
government  agencies.  U.S.  federal  government  agencies  are  among  our  most  significant  clients.  We
generated  37.2%  of  our  revenue  for  fiscal  2012  from  the  following  agencies:  14.4%  from  DoD  agencies,
9.2% from USAID and 13.6% from other U.S. federal government agencies. A significant amount of this
revenue  is  derived  under  multi-year  contracts,  many  of  which  are  appropriated  on  an  annual  basis.  As  a
result,  at  the  beginning  of  a  project,  the  related  contract  may  be  only  partially  funded,  and  additional
funding  is  normally  committed  only  as  appropriations  are  made  in  each  subsequent  year.  These
appropriations,  and  the  timing  of  payment  of  appropriated  amounts,  may  be  influenced  by  numerous
factors as noted below. Our backlog includes only the projects that  have funding appropriated.

The demand for our U.S. government-related services is generally driven by the level of government
program funding. Accordingly, the success and further development of our business depends, in large part,
upon the continued funding of these U.S. government programs, and upon our ability to obtain contracts
and  perform  well  under  these  programs.  There  are  several  factors  that  could  materially  affect  our  U.S.
government contracting business, including the following:

(cid:129) the failure of the U.S. government to complete its budget process before its fiscal year-end, which
results in the funding of government operations by means of a continuing resolution that authorizes

32

agencies  to  continue  to  operate  but  does  not  authorize  new  spending  initiatives.  As  a  result,  U.S.
government agencies may delay the procurement of services;

(cid:129) changes in and delays or cancellations of government programs,  requirements or  appropriations;

(cid:129) budget constraints or policy changes resulting in delay or curtailment of expenditures related to the

services we provide;

(cid:129) re-competes of government contracts;

(cid:129) the  timing  and  amount  of  tax  revenue  received  by  federal,  state  and  local  governments,  and  the

overall level of government expenditures;

(cid:129) curtailment in the use of government  contracting firms;

(cid:129) delays associated with insufficient numbers  of  government staff to oversee contracts;

(cid:129) the  increasing  preference  by  government  agencies  for  contracting  with  small  and  disadvantaged

businesses;

(cid:129) competing  political  priorities  and  changes  in  the  political  climate  with  regard  to  the  funding  or

operation of the services we provide;

(cid:129) the  adoption  of  new  laws  or  regulations  affecting  our  contracting  relationships  with  the  federal,

state or local governments;

(cid:129) unsatisfactory  performance  on  government  contracts  by  us  or  one  of  our  subcontractors,  negative
government audits, or other events that may impair our relationship with the federal, state or local
governments;

(cid:129) a dispute with or improper activity by any of our  subcontractors; and

(cid:129) general economic or political conditions.

These and other factors could cause U.S. government agencies to delay or cancel programs, to reduce
their  orders  under  existing  contracts,  to  exercise  their  rights  to  terminate  contracts  or  not  to  exercise
contract options for renewals or extensions. Any of these actions could have a material adverse effect on
our  revenue or timing of contract payments  from these agencies.

As a U.S. government contractor, we must comply with various procurement laws and regulations and are
subject to regular government audits; a violation of any of these laws and regulations or the failure to pass a
government  audit  could  result  in  sanctions,  contract  termination,  forfeiture  of  profit,  harm  to  our
reputation  or  loss  of  our  status  as  an  eligible  government  contractor  and  could  reduce  our  profits  and
revenue.

We  must  comply  with  and  are  affected  by  U.S.  federal,  state,  local  and  foreign  laws  and  regulations
relating to the formation, administration and performance of government contracts. For example, we must
comply with FAR, the Truth in Negotiations Act, CAS, the American Recovery and Reinvestment Act of
2009, the Services Contract Act and DoD security regulations, as well as many other rules and regulations.
In  addition,  we  must  also  comply  with  other  government  regulations  related  to  employment  practices,
environmental  protection,  health  and  safety,  tax,  accounting  and  anti-fraud  measures,  as  well  as  many
others  regulations  in  order  to  maintain  our  government  contractor  status.  These  laws  and  regulations
affect how we do business with our clients and, in some instances, impose additional costs on our business
operations. Although we take precautions to prevent and deter fraud, misconduct and non-compliance, we
face the risk that our employees or outside partners may engage in misconduct, fraud or other improper
activities.  U.S.  government  agencies,  such  as  the  DCAA,  routinely  audit  and  investigate  government
contractors. These government agencies review and audit a government contractor’s performance under its
contracts and cost structure, and evaluate compliance with applicable laws, regulations and standards. In

33

addition, during the course of its audits, the DCAA may question our incurred project costs. If the DCAA
believes we have accounted for such costs in a manner inconsistent with the requirements for FAR or CAS,
the DCAA auditor may recommend to our U.S. government corporate administrative contracting officer
to  disallow  such  costs.  Historically,  we  have  not  experienced  significant  disallowed  costs  as  a  result  of
government audits. However, we can provide no assurance that the DCAA or other government audits will
not result in material disallowance for incurred costs in the future. In addition, U.S. government contracts
are subject to a variety of other requirements relating to the formation, administration, performance and
accounting for these contracts. We may also be subject to qui tam litigation brought by private individuals
on behalf of the U.S. government under the Federal Civil False Claims Act, which could include claims for
treble  damages.  U.S.  government  contract  violations  could  result  in  the  imposition  of  civil  and  criminal
penalties  or  sanctions,  contract  termination,  forfeiture  of  profit  and/or  suspension  of  payment,  any  of
which  could  make  us  lose  our  status  as  an  eligible  government  contractor.  We  could  also  suffer  serious
harm to our reputation. Any interruption or termination of our U.S. government contractor status could
reduce our profits and revenue significantly.

Our  inability  to  win  or  renew  U.S.  government  contracts  during  regulated  procurement  processes  could
harm our operations and significantly reduce or eliminate our profits.

U.S.  government  contracts  are  awarded  through  a  regulated  procurement  process.  The  U.S.  federal
government  has  increasingly  relied  upon  multi-year  contracts  with  pre-established  terms  and  conditions,
such  as  indefinite  delivery/indefinite  quantity  (‘‘IDIQ’’)  contracts,  which  generally  require  those
contractors  who  have  previously  been  awarded  the  IDIQ  to  engage  in  an  additional  competitive  bidding
process  before  a  task  order  is  issued.  As  a  result,  new  work  awards  tend  to  be  smaller  and  of  shorter
duration,  since  the  orders  represent  individual  tasks  rather  than  large,  programmatic  assignments.  The
increased competition, in turn, may require us to make sustained efforts to reduce costs in order to realize
revenue and 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,  the  U.S.
federal  government  has  announced  its  intention  to  scale  back  outsourcing  of  services  in  favor  of
‘‘insourcing’’ jobs to its employees, which could reduce our revenue. Moreover, even if we are qualified to
work  on  a  government  contract,  we  may  not  be  awarded  the  contract  because  of  existing  government
policies designed to protect small businesses and underrepresented minority contractors. Our inability to
win  or  renew  government  contracts  during  regulated  procurement  processes  could  harm  our  operations
and significantly reduce or eliminate  our  profits.

Each year, client funding for some of our U.S. government contracts may rely on government appropriations
or public-supported financing. If adequate public funding is delayed or is not available, then our profits and
revenue could decline.

Each year, client funding for some of our U.S. government contracts may directly or indirectly rely on
government appropriations or public-supported financing. Legislatures may appropriate funds for a given
project  on  a  year-by-year  basis,  even  though  the  project  may  take  more  than  one  year  to  perform.  In
addition,  public-supported  financing  such  as  U.S.  state  and  local  municipal  bonds  may  be  only  partially
raised to support existing projects. The outcome of ongoing political debate in Congress regarding cuts to
federal government spending could result in reductions in the funding proposed by the Administration for
certain  projects.  The  Budget  Control  Act  includes  significant  reductions  in  U.S.  federal  government
spending  over  a  10-year  period.  Similarly,  the  impact  of  the  economic  downturn  on  U.S.  state  and  local
governments may make it more difficult for them to fund projects. In addition to the state of the economy
and competing political priorities, public funds and the timing of payment of these funds may be influenced
by, among other things, curtailments in the use of government contracting firms, increases in raw material
costs,  delays  associated  with  insufficient  numbers  of  government  staff  to  oversee  contracts,  budget
constraints,  the  timing  and  amount  of  tax  receipts  and  the  overall  level  of  government  expenditures.  If
adequate public funding is not available  or is delayed, then our profits and  revenue could decline.

Our  U.S.  federal  government  contracts  may  give  government  agencies  the  right  to  modify,  delay,  curtail,
renegotiate or terminate existing contracts at their convenience at any time prior to their completion, which
may result in a decline in our profits and  revenue.

U.S. federal government projects in which we participate as a contractor or subcontractor may extend
for several years. Generally, government contracts include the right to modify, delay, curtail, renegotiate or
terminate contracts and subcontracts at the government’s convenience any time prior to their completion.
Any  decision  by  a  U.S.  federal  government  client  to  modify,  delay,  curtail,  renegotiate  or  terminate  our
contracts at their convenience may result in a decline in  our profits and revenue.

Our international operations expose us to legal, political and economic risks that could harm our business
and financial results. For example, we could be adversely affected by violations of the U.S. Foreign Corrupt
Practices Act and similar worldwide anti-bribery  laws.

In  fiscal  2012,  we  generated  24.5%  of  our  revenue  from  our  international  operations,  primarily  in
Canada,  and  from  international  clients  for  work  that  is  performed  by  our  domestic  operations.
International business is subject to a  variety of risks,  including:

(cid:129) potential non-compliance with a wide variety of laws and regulations, including anti-corruption and

anti-boycott rules, trade and export control  regulations, and other international  regulations;

(cid:129) lack of developed legal systems to  enforce contractual rights;

(cid:129) greater risk of uncollectible accounts and longer collection cycles;

(cid:129) currency exchange rate fluctuations,  devaluations and other conversion restrictions;

(cid:129) the potential for civil unrest, acts of terrorism and greater physical security risks, which may cause

us to leave a country quickly;

(cid:129) logistical and communication challenges;

(cid:129) imposition  of  governmental  controls  and  potentially  adverse  changes  in  laws  and  regulatory

practices, including tariffs and taxes;

(cid:129) changes in labor conditions; and

(cid:129) general economic, political and financial  conditions  in foreign  markets.

International  risks  and  violations  of  international  regulations  may  significantly  reduce  our  revenue
and  profits,  and  subject  us  to  criminal  or  civil  enforcement  actions,  including  fines,  suspensions  or
disqualification from future U.S. federal  procurement contracting.

The  U.S.  Foreign  Corrupt  Practices  Act  (‘‘FCPA’’)  and  similar  anti-bribery  laws  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’’ 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.  Practices  in  the  local  business  community  of  many  countries  outside  the
U.S.  have  a  level  of  government  corruption  that  is  greater  than  that  found  in  the  developed  world.  Our
policies mandate compliance with these anti-bribery laws and we have established policies and procedures
designed to monitor compliance with these anti-bribery law requirements; however, we cannot ensure that
our policies and procedures will protect us from potential reckless or criminal acts committed by individual
employees  or  agents.  If  we  are  found  to  be  liable  for  anti-bribery  law  violations  we  could  suffer  from
criminal or civil penalties or other sanctions that could have a material adverse effect on  our business.

If we fail to complete a project in a timely manner, miss a required performance standard or otherwise fail
to adequately perform on a project, then we may incur a loss on that project, which may reduce or eliminate
our overall profitability.

Our engagements often involve large-scale, complex projects. The quality of our performance on such
projects depends in large part upon our ability to manage the relationship with our clients and our ability
to effectively manage the project and deploy appropriate resources, including third-party contractors and
our  own  personnel,  in  a  timely  manner.  We  may  commit  to  a  client  that  we  will  complete  a  project  by  a
scheduled date. We may also commit that a project, when completed, will achieve specified performance
standards.  If  the  project  is  not  completed  by  the  scheduled  date  or  fails  to  meet  required  performance
standards, we may either incur significant additional costs or be held responsible for the costs incurred by
the  client  to  rectify  damages  due  to  late  completion  or  failure  to  achieve  the  required  performance
standards.  The  uncertainty  of  the  timing  of  a  project  can  present  difficulties  in  planning  the  amount  of
personnel  needed  for  the  project.  If  the  project  is  delayed  or  canceled,  we  may  bear  the  cost  of  an
underutilized  workforce  that  was  dedicated  to  fulfilling  the  project.  In  addition,  performance  of  projects
can be affected by a number of factors beyond our control, including unavoidable delays from government
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 and other factors. To the extent these events occur, the total costs
of the project could exceed our estimates, and we could experience reduced profits or, in some cases, incur
a loss on a project, which may reduce or eliminate our overall profitability. Further, any defects or errors,
or failures to meet our clients’ expectations, could result in claims for damages against us. Our contracts
generally  limit  our  liability  for  damages  that  arise  from  negligent  acts,  errors,  mistakes  or  omissions  in
rendering services to our clients. However, we cannot be sure that these contractual provisions will protect
us from liability for damages in the event  we are sued.

The  loss  of  key  personnel  or  our  inability  to  attract  and  retain  qualified  personnel  could  significantly
disrupt  our business.

As primarily a professional and technical services company, we are labor-intensive and, therefore, our
ability to attract, retain and expand our senior management and our professional and technical staff is an
important  factor  in  determining  our  future  success.  The  market  for  qualified  scientists  and  engineers  is
competitive and, from time to time, it may be difficult to attract and retain qualified individuals with the
required  expertise  within  the  timeframe  demanded  by  our  clients.  For  example,  some  of  our  U.S.
government contracts may require us to employ only individuals who have particular government security
clearance levels. In addition, we rely heavily upon the expertise and leadership of our senior management.
If  we  are  unable  to  retain  executives  and  other  key  personnel,  the  roles  and  responsibilities  of  those
employees will need to be filled, which may require that we devote time and resources to identify, hire and
integrate new employees. With limited exceptions, we do not have employment agreements with any of our
key personnel. The loss of the services of any of these key personnel could adversely affect our business.
Although  we  have  obtained  non-compete  agreements  from  certain  principals  and  stockholders  of
companies we have acquired, we generally do not have non-compete or employment agreements with key
employees  who  were  once  equity  holders  of  these  companies.  Further,  many  of  our  non-compete
agreements  have  expired.  We  do  not  maintain  key-man  life  insurance  policies  on  any  of  our  executive
officers  or  senior  managers.  Our  failure  to  attract  and  retain  key  individuals  could  impair  our  ability  to
provide services to our clients and conduct our business effectively.

Our actual business and financial results could differ from the estimates and assumptions that we use to
prepare our financial statements, which may significantly reduce or eliminate  our profits.

To  prepare  financial  statements  in  conformity  with  U.S.  generally  accepted  accounting  principles
(‘‘GAAP’’),  management  is  required  to  make  estimates  and  assumptions  as  of  the  date  of  the  financial

36

statements. These estimates and assumptions affect the reported values of assets, liabilities, revenue and
expenses,  as  well  as  disclosures  of  contingent  assets  and  liabilities.  For  example,  we  typically  recognize
revenue over the life of a contract based on the proportion of costs incurred to date compared to the total
costs  estimated  to  be  incurred  for  the  entire  project.  Areas  requiring  significant  estimates  by  our
management include:

(cid:129) the application of the percentage-of-completion method of accounting and revenue recognition on

contracts, change orders and contract claims including related unbilled accounts receivable;

(cid:129) unbilled  accounts  receivable  including  amounts  related  to  requests  for  equitable  adjustment  to
contracts that provide for price redetermination, primarily with the U.S. federal government. These
amounts are recorded only when they can  be  reliably estimated  and realization  is probable;

(cid:129) provisions  for  uncollectible  receivables,  client  claims  and  recoveries  of  costs  from  subcontractors,

vendors and others;

(cid:129) provisions  for  income  taxes,  research  and  experimentation  (‘‘R&E’’)  credits,  valuation  allowances

and unrecognized tax benefits;

(cid:129) value of goodwill and recoverability  of other intangible assets;

(cid:129) valuations of assets acquired and liabilities assumed in connection with business combinations;

(cid:129) valuation of contingent earn-out liabilities  in connection  with business combinations;

(cid:129) valuation of employee benefit plans;

(cid:129) valuation of stock-based compensation expense; and

(cid:129) accruals for estimated liabilities, including  litigation and insurance reserves.

Our  actual  business  and  financial  results  could  differ  from  those  estimates,  which  may  significantly

reduce or eliminate our profits.

Our profitability could suffer if we are not able to  maintain adequate utilization of our workforce.

The cost of providing our services, including the extent to which we utilize our workforce, affects our

profitability. The rate at which we utilize our workforce  is affected  by a number  of  factors, including:

(cid:129) our  ability  to  transition  employees  from  completed  projects  to  new  assignments  and  to  hire  and

assimilate new employees;

(cid:129) our ability to forecast demand for our services and thereby maintain an appropriate headcount in

each  of our geographies and workforces;

(cid:129) our ability to manage attrition;

(cid:129) our need to devote time and resources to training, business development, professional development

and other non-chargeable activities; and

(cid:129) our ability to match the skill sets of our employees to the  needs  of the marketplace.

If we over-utilize our workforce, our employees may become disengaged, which will impact employee

attrition. If we under-utilize our workforce, our  profit margin  and profitability could suffer.

Our  use  of  the  percentage-of-completion  method  of  revenue  recognition  could  result  in  a  reduction  or
reversal of previously recorded revenue and  profits.

We  account  for  most  of  our  contracts  on  the  percentage-of-completion  method  of  revenue
recognition. Generally, our use of this method results in recognition of revenue and profit ratably over the

37

life of the contract, based on the proportion of costs incurred to date to total costs expected to be incurred
for the entire project. The effects of revisions to revenue and estimated costs, including the achievement of
award fees as well as the impact of change orders and claims, are recorded when the amounts are known
and  can  be  reasonably  estimated.  Such  revisions  could  occur  in  any  period  and  their  effects  could  be
material.  Although  we  have  historically  made  reasonably  reliable  estimates  of  the  progress  towards
completion of long-term contracts, the uncertainties inherent in the estimating process make it possible for
actual  costs  to  vary  materially  from  estimates,  including  reductions  or  reversals  of  previously  recorded
revenue and profit.

If we are unable to accurately estimate and control our contract costs, then we may incur losses on our
contracts, which could decrease our operating margins and reduce our profits. In particular, our fixed-price
contracts could increase the unpredictability of our  earnings.

It  is  important  for  us  to  accurately  estimate  and  control  our  contract  costs  so  that  we  can  maintain
positive operating margins and profitability. We generally enter into three principal types of contracts with
our  clients: fixed-price, time-and-materials  and  cost-plus.

The U.S. federal government and some clients have increased the use of fixed-priced contracts. Under
fixed-price contracts, we receive a fixed price irrespective of the actual costs we incur and, consequently,
we are exposed to a number of risks. We realize a profit on fixed-price contracts only if we can control our
costs  and  prevent  cost  over-runs  on  our  contracts.  Fixed-price  contracts  require  cost  and  scheduling
estimates that are based on a number of assumptions, including those about future economic conditions,
costs  and  availability  of  labor,  equipment  and  materials,  and  other  exigencies.  We  could  experience  cost
overruns  if  these  estimates  are  originally  inaccurate  as  a  result  of  errors  or  ambiguities  in  the  contract
specifications, or become inaccurate as a result of a change in circumstances following the submission of
the estimate due to, among other things, unanticipated technical problems, difficulties in obtaining permits
or  approvals,  changes  in  local  laws  or  labor  conditions,  weather  delays,  changes  in  the  costs  of  raw
materials,  or  inability  of  our  vendors  or  subcontractors  to  perform.  If  cost  overruns  occur,  we  could
experience reduced profits or, in some cases, a loss for that project. If a project is significant, or if there are
one  or  more  common  issues  that  impact  multiple  projects,  costs  overruns  could  increase  the
unpredictability  of  our  earnings  as  well  as  have  a  material  adverse  impact  on  our  business  and  earnings.

Under our time-and-materials contracts, we are paid for labor at negotiated hourly billing rates and
also  paid  for  other  expenses.  Profitability  on  these  contracts  is  driven  by  billable  headcount  and  cost
control.  Many  of  our  time-and-materials  contracts  are  subject  to  maximum  contract  values  and,
accordingly,  revenue  relating  to  these  contracts  is  recognized  as  if  these  contracts  were  fixed-price
contracts.  Under  our  cost-plus  contracts,  some  of  which  are  subject  to  contract  ceiling  amounts,  we  are
reimbursed for allowable costs and fees, which may be fixed or performance-based. If our costs exceed the
contract ceiling or are not allowable under the provisions of the contract or any applicable regulations, we
may not be able to obtain reimbursement  for all of the  costs we incur.

Profitability  on  our  contracts  is  driven  by  billable  headcount  and  our  ability  to  manage  our
subcontractors,  vendors  and  material  suppliers.  If  we  are  unable  to  accurately  estimate  and  manage  our
costs, we may incur losses on our contracts, which could decrease our operating margins and significantly
reduce or eliminate our profits. Certain of our contracts require us to satisfy specific design, engineering,
procurement or construction milestones in order to receive payment for the work completed or equipment
or  supplies  procured  prior  to  achievement  of  the  applicable  milestone.  As  a  result,  under  these  types  of
arrangements, we may incur significant costs or perform significant amounts of services prior to receipt of
payment. If a client determines not to proceed with the completion of the project or if the client defaults
on its payment obligations, we may face difficulties in collecting payment of amounts due to us for the costs
previously incurred or for the amounts  previously  expended to purchase equipment or  supplies.

38

Accounting  for  a  contract  requires  judgments  relative  to  assessing  the  contract’s  estimated  risks,
revenue,  costs  and  other  technical  issues.  Due  to  the  size  and  nature  of  many  of  our  contracts,  the
estimation  of  overall  risk,  revenue  and  cost  at  completion  is  complicated  and  subject  to  many  variables.
Changes  in  underlying  assumptions,  circumstances  or  estimates  may  also  adversely  affect  future  period
financial performance. If we are unable to accurately estimate the overall revenue or costs on a contract,
then we may experience a lower profit  or  incur a loss  on the contract.

Our failure to win new contracts and renew existing contracts with private and public sector clients could
adversely affect our profitability.

Our  business  depends  on  our  ability  to  win  new  contracts  and  renew  existing  contracts  with  private
and public sector clients. Contract proposals and negotiations are complex and frequently involve a lengthy
bidding  and  selection  process,  which  is  affected  by  a  number  of  factors.  These  factors  include  market
conditions,  financing  arrangements  and  required  governmental  approvals.  For  example,  a  client  may
require us to provide a bond or letter of credit to protect the client should we fail to perform under the
terms  of  the  contract.  If  negative  market  conditions  arise,  or  if  we  fail  to  secure  adequate  financial
arrangements  or  the  required  government  approval,  we  may  not  be  able  to  pursue  particular  projects,
which  could adversely affect our profitability.

We have made and expect to continue to make acquisitions that could disrupt our operations and adversely
impact our business and operating results. Our failure to conduct due diligence effectively or our inability
to successfully integrate acquisitions could impede us from realizing all of the benefits of the acquisitions,
which could weaken our results of operations.

A key part of our growth strategy is to acquire other companies that complement our lines of business
or  that  broaden  our  technical  capabilities  and  geographic  presence.  We  expect  to  continue  to  acquire
companies  as  an  element  of  our  growth  strategy;  however,  our  ability  to  make  acquisitions  is  restricted
under our credit agreement. Acquisitions involve certain known and unknown risks that could cause our
actual growth or operating results to differ from our expectations or the expectations of securities analysts.
For example:

(cid:129) we may not be able to identify suitable acquisition candidates or to acquire additional companies on

acceptable terms;

(cid:129) we  are  pursuing  international  acquisitions,  which  inherently  pose  more  risk  than  domestic

acquisitions;

(cid:129) we  compete  with  others  to  acquire  companies,  which  may  result  in  decreased  availability  of,  or

increased price for, suitable acquisition  candidates;

(cid:129) we may not be able to obtain the necessary financing, on favorable terms or at all, to finance any of

our  potential acquisitions;

(cid:129) we may ultimately fail to consummate an acquisition even if we announce that we plan to acquire a

company; and

(cid:129) acquired companies may not perform as we expect, and we may fail to realize anticipated revenue

and profits.

In  addition,  our  acquisition  strategy  may  divert  management’s  attention  away  from  our  existing
businesses, resulting in the loss of key clients or key employees, and expose us to unanticipated problems
or legal liabilities, including responsibility as a successor-in-interest for undisclosed or contingent liabilities
of acquired businesses or assets.

If  we  fail  to  conduct  due  diligence  on  our  potential  targets  effectively,  we  may,  for  example,  not
identify problems at target companies or fail to recognize incompatibilities or other obstacles to successful

39

integration. Our inability to successfully integrate future acquisitions could impede us from realizing all of
the  benefits  of  those  acquisitions  and  could  severely  weaken  our  business  operations.  The  integration
process  may  disrupt  our  business  and,  if  implemented  ineffectively,  may  preclude  realization  of  the  full
benefits expected by us and could harm our results of operations. In addition, the overall integration of the
combining  companies  may  result  in  unanticipated  problems,  expenses,  liabilities,  and  competitive
responses, and may cause our stock price to decline. The difficulties of integrating an acquisition include,
among others:

(cid:129) issues  in integrating information, communications and other systems;

(cid:129) incompatibility of logistics, marketing and administration methods;

(cid:129) maintaining employee morale and retaining key employees;

(cid:129) integrating the business cultures of  both companies;

(cid:129) preserving important strategic client  relationships;

(cid:129) consolidating  corporate  and  administrative  infrastructures  and  eliminating  duplicative  operations;

and

(cid:129) coordinating geographically separate  organizations.

In addition, even if the operations of an acquisition are integrated successfully, we may not realize the
full benefits of the acquisition, including the synergies, cost savings or growth opportunities that we expect.
These benefits may not be achieved within the  anticipated time frame,  or at  all.

Further, acquisitions may cause us to:

(cid:129) issue common stock that would dilute our current stockholders’  ownership percentage;

(cid:129) use a substantial portion of our cash  resources;

(cid:129) increase our interest expense, leverage and debt service requirements (if we incur additional debt to

pay for an acquisition);

(cid:129) assume  liabilities,  including  environmental  liabilities,  for  which  we  do  not  have  indemnification
from the former owners. Further, indemnification obligations may be subject to dispute or concerns
regarding the creditworthiness of the  former owners;

(cid:129) record  goodwill  and  non-amortizable  intangible  assets  that  are  subject  to  impairment  testing  and

potential impairment charges;

(cid:129) experience  volatility  in  earnings  due  to  changes  in  contingent  consideration  related  to  acquisition

earn-out liability estimates;

(cid:129) incur amortization expenses related to certain  intangible assets;

(cid:129) lose existing or potential contracts  as a result  of conflict of interest issues;

(cid:129) incur large and immediate write-offs; or

(cid:129) become subject to litigation.

Finally,  acquired  companies  that  derive  a  significant  portion  of  their  revenue  from  the  U.S.  federal
government and that do not follow the same cost accounting policies and billing practices that we follow
may  be  subject  to  larger  cost  disallowances  for  greater  periods  than  we  typically  encounter.  If  we  fail  to
determine  the  existence  of  unallowable  costs  and  do  not  establish  appropriate  reserves  in  advance  of  an
acquisition, we may be exposed to material unanticipated liabilities, which could have a material adverse
effect on our business.

40

If our goodwill or other intangible assets become impaired, then our profits may be significantly reduced.

Because  we  have  historically  acquired  a  significant  number  of  companies,  goodwill  and  other
intangible  assets  represent  a  substantial  portion  of  our  assets.  At  September  30,  2012,  our  goodwill  was
$636.0  million  and  other  intangible  assets  were  $74.2  million.  We  are  required  to  perform  a  goodwill
impairment test for potential impairment at least on an annual basis. We also assess the recoverability of
the  unamortized  balance  of  our  intangible  assets  when  indications  of  impairment  are  present  based  on
expected  future  profitability  and  undiscounted  expected  cash  flows  and  their  contribution  to  our  overall
operations.  The  goodwill  impairment  test  requires  us  to  determine  the  fair  value  of  our  reporting  units,
which  are  the  components  one  level  below  our  reportable  segments.  In  determining  fair  value,  we  make
significant  judgments  and  estimates,  including  assumptions  about  our  strategic  plans  with  regard  to  our
operations.  We  also  analyze  current  economic  indicators  and  market  valuations  to  help  determine  fair
value.  To  the  extent  economic  conditions  that  would  impact  the  future  operations  of  our  reporting  units
change,  our  goodwill  may  be  deemed  to  be  impaired,  and  we  would  be  required  to  record  a  non-cash
charge  that could result in a material  adverse effect on  our financial position  or results of  operations.

If we are not able to successfully manage our growth strategy, our business and results of operations may be
adversely affected.

Our  expected  future  growth  presents  numerous  managerial,  administrative,  operational  and  other
challenges. Our ability to manage the growth of our operations will require us to continue to improve our
management information systems and our other internal systems and controls. In addition, our growth will
increase  our  need  to  attract,  develop,  motivate  and  retain  both  our  management  and  professional
employees.  The  inability  to  effectively  manage  our  growth  or  the  inability  of  our  employees  to  achieve
anticipated performance could have a  material adverse effect on our business.

Our backlog is subject to cancellation and unexpected adjustments, and is an uncertain indicator of future
operating results.

Our backlog at September 30, 2012, was $2.1 billion. We include in backlog only those contracts for
which funding has been provided and work authorizations have been received. We cannot guarantee that
the  revenue  projected  in  our  backlog  will  be  realized  or,  if  realized,  will  result  in  profits.  In  addition,
project cancellations or scope adjustments may occur, from time to time, with respect to contracts reflected
in our backlog. For example, certain of our contracts with the U.S. federal government and other clients
are  terminable  at  the  discretion  of  the  client,  with  or  without  cause.  These  types  of  backlog  reductions
could  adversely  affect  our  revenue  and  margins.  Accordingly,  our  backlog  as  of  any  particular  date  is  an
uncertain indicator of our future earnings.

If our business partners fail to perform their contractual obligations on a project, we could be exposed to
legal liability, loss of reputation and  profit reduction or loss  on the project.

We  routinely  enter  into  subcontracts  and,  occasionally,  joint  ventures,  teaming  arrangements  and
other  contractual  arrangements  so  that  we  can  jointly  bid  and  perform  on  a  particular  project.  Success
under these arrangements depends in large part on whether our business partners fulfill their contractual
obligations satisfactorily. In addition, when we operate through a joint venture in which we are a minority
holder,  we  have  limited  control  over  many  project  decisions,  including  decisions  related  to  the  joint
venture’s  internal  controls,  which  may  not  be  subject  to  the  same  internal  control  procedures  that  we
employ. If these unaffiliated third parties do not fulfill their contract obligations, the partnerships or joint
ventures  may  be  unable  to  adequately  perform  and  deliver  their  contracted  services.  Under  these
circumstances,  we  may  be  obligated  to  pay  financial  penalties,  provide  additional  services  to  ensure  the
adequate performance and delivery of the contracted services and may be jointly and severally liable for
the  other’s  actions  or  contract  performance.  These  additional  obligations  could  result  in  reduced  profits

41

and revenues or, in some cases, significant losses for us with respect to the joint venture, which could also
affect our reputation in the industries  we serve.

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

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

We  also  rely  on  relationships  with  other  contractors  when  we  act  as  their  subcontractor  or  joint
venture  partner.  The  absence  of  qualified  subcontractors  with  which  we  have  a  satisfactory  relationship
could  adversely  affect  the  quality  of  our  service  and  our  ability  to  perform  under  some  of  our  contracts.
Our  future  revenue  and  growth  prospects  could  be  adversely  affected  if  other  contractors  eliminate  or
reduce  their  subcontracts  or  teaming  arrangement  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.

We may be required to pay liquidated damages if we fail to meet milestone requirements in our contracts.

We  may  be  required  to  pay  liquidated  damages  if  we  fail  to  meet  milestone  requirements  in  our
contracts.  Failure  to  meet  any  of  the  milestone  requirements  could  result  in  additional  costs,  and  the
amount of such additional costs could exceed the projected profits on the project. These additional costs
include  liquidated  damages  paid  under  contractual  penalty  provisions,  which  can  be  substantial  and  can
accrue on a regular basis.

Changes  in  resource  management,  environmental  or  infrastructure  industry  laws,  regulations  and
programs could directly or indirectly reduce the demand for our services, which could in turn negatively
impact our revenue.

Some  of  our  services  are  directly  or  indirectly  impacted  by  changes  in  U.S.  federal,  state,  local  or
foreign  laws  and  regulations  pertaining  to  resource  management,  the  environment  and  infrastructure.
Accordingly,  a  relaxation  or  repeal  of  these  laws  and  regulations,  or  changes  in  governmental  policies
regarding  the  funding,  implementation  or  enforcement  of  these  programs,  could  result  in  a  decline  in
demand for our services, which could  in  turn negatively impact our revenue.

Changes in capital markets could adversely affect our access to capital and negatively impact our business.

Our results could be adversely affected by an inability to access the revolving credit facility under our
credit agreement. Unfavorable financial or economic conditions could impact certain lenders’ willingness
or  ability  to  fund  our  revolving  credit  facility.  In  addition,  increases  in  interest  rates  or  credit  spreads,
volatility  in  financial  markets  or  the  interest  rate  environment,  significant  political  or  economic  events,
defaults  of  significant  issuers  and  other  market  and  economic  factors  may  negatively  impact  the  general
level  of  debt  issuance,  the  debt  issuance  plans  of  certain  categories  of  borrowers,  the  types  of  credit-
sensitive  products  being  offered,  and/or  a  sustained  period  of  market  decline  or  weakness  could  have  a
material adverse effect on us.

42

Restrictive covenants in our credit agreement may restrict our ability to pursue certain business strategies.

Our credit agreement limits or restricts our ability to, among other things:

(cid:129) incur additional indebtedness;

(cid:129) create liens securing debt or other encumbrances on our  assets;

(cid:129) make loans or advances;

(cid:129) pay dividends or make distributions to our stockholders;

(cid:129) purchase or redeem our stock;

(cid:129) repay indebtedness that is junior to indebtedness under our credit agreement;

(cid:129) acquire the assets of, or merge or  consolidate with, other  companies; and

(cid:129) sell, lease or otherwise dispose of assets.

Our credit agreement also requires that we maintain certain financial ratios, which we may not be able
to achieve. The covenants may impair our ability to finance future operations or capital needs or to engage
in other favorable business activities.

Our industry is highly competitive and  we may be unable to compete effectively.

Our industry is highly fragmented and intensely competitive. Our competitors are numerous, ranging
from  small  private  firms  to  multi-billion-dollar  public  companies.  In  addition,  the  technical  and
professional aspects of our services generally do not require large upfront capital expenditures and provide
limited  barriers  against  new  competitors.  Some  of  our  competitors  have  achieved  greater  market
penetration  in  some  of  the  markets  in  which  we  compete,  and  some  have  substantially  more  financial
resources and/or financial flexibility than we do. As a result of the number of competitors in the industry,
our clients may select one of our competitors on a project due to competitive pricing or a specific skill set.
These  competitive  forces  could  force  us  to  make  price  concessions  or  otherwise  reduce  prices  for  our
services.  If  we  are  unable  to  maintain  our  competitiveness,  our  market  share,  revenue  and  profits  will
decline.

Legal proceedings, investigations and disputes could result in substantial monetary penalties and damages,
especially if such penalties and damages  exceed  or  are  excluded from existing insurance  coverage.

We engage in consulting, engineering, program management, construction management, construction
and  technical  services  that  can  result  in  substantial  injury  or  damages  that  may  expose  us  to  legal
proceedings, investigations and disputes. For example, in the ordinary course of our business, we may be
involved  in  legal  disputes  regarding  personal  injury  claims,  employee  or  labor  disputes,  professional
liability claims, and general commercial disputes involving project cost overruns and liquidated damages as
well as other claims. 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,  and  we  may  be  deemed  to  be  responsible  for  these  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. We maintain insurance coverage as part of our overall legal
and risk management strategy to minimize our potential liabilities; however, insurance coverage contains
exclusions  and  other  limitations  that  may  not  cover  our  potential  liabilities.  Generally,  our  insurance
program  covers  workers’  compensation  and  employer’s  liability,  general  liability,  automobile  liability,
professional  errors  and  omissions  liability,  property,  and  contractor’s  pollution  liability  (in  addition  to
other policies for specific projects). Our insurance program includes deductibles or self-insured retentions
for each covered claim that may increase over time. In addition, our insurance policies contain exclusions
that  insurance  providers  may  use  to  deny  or  restrict  coverage.  Excess  liability  and  professional  liability

43

insurance policies provide for coverage on a ‘‘claims-made’’ basis, covering only claims actually made and
reported  during  the  policy  period  currently  in  effect.  If  we  sustain  liabilities  that  exceed  or  that  are
excluded  from  our  insurance  coverage  or  for  which  we  are  not  insured,  it  could  have  a  material  adverse
impact on our results of operations and  financial condition.

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.

Our inability to obtain adequate bonding could have a material adverse effect on our future revenue and
business  prospects.

Certain  clients  require  bid  bonds  and  performance  and  payment  bonds.  These  bonds  indemnify  the
client  should  we  fail  to  perform  our  obligations  under  a  contract.  If  a  bond  is  required  for  a  particular
project and we are unable to obtain an appropriate bond, we cannot pursue that project. In some instances,
we are required to co-venture with a small or disadvantaged business to pursue certain U.S. federal or state
government contracts. In connection with these ventures, we are sometimes required to utilize our bonding
capacity  to  cover  all  of  the  payment  and  performance  obligations  under  the  contract  with  the  client.  We
have a bonding facility but, as is typically the case, the issuance of bonds under that facility is at the surety’s
sole  discretion.  Moreover,  due  to  events  that  can  negatively  affect  the  insurance  and  bonding  markets,
bonding may be more difficult to obtain or may only be available at significant additional cost. There can
be no assurance that bonds will continue to be available to us on reasonable terms. Our inability to obtain
adequate bonding and, as a result, to bid on new work could have a material adverse effect on our future
revenue and business prospects.

Employee, agent or partner misconduct or our overall failure to comply with laws or regulations could harm
our reputation, reduce our revenue and profits, and subject us to criminal and civil enforcement actions.

Misconduct, fraud, non-compliance with applicable laws and regulations, or other improper activities
by one of our employees, agents or partners could have a significant negative impact on our business and
reputation.  Such  misconduct  could  include  the  failure  to  comply  with  government  procurement
regulations, regulations regarding the protection of classified information, regulations prohibiting bribery
and  other  foreign  corrupt  practices,  regulations  regarding  the  pricing  of  labor  and  other  costs  in
government  contracts,  regulations  on  lobbying  or  similar  activities,  regulations  pertaining  to  the  internal
controls  over  financial  reporting,  environmental  laws  and  any  other  applicable  laws  or  regulations.  For
example,  the  FCPA  and  similar  anti-bribery  laws  in  other  jurisdictions  generally  prohibit  companies  and
their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or
retaining  business.  Our  policies  mandate  compliance  with  these  regulations  and  laws,  and  we  take
precautions to prevent and detect misconduct. However, since our internal controls are subject to inherent
limitations, including human error, it is possible that these controls could be intentionally circumvented or
become  inadequate  because  of  changed  conditions.  As  a  result,  we  cannot  assure  that  our  controls  will
protect us from reckless or criminal acts committed by our employees or agents. Our failure to comply with
applicable laws or regulations or acts of misconduct could subject us to fines and penalties, loss of security
clearances, and suspension or debarment from contracting, any or all of which could harm our reputation,
reduce our revenue and profits, and  subject us  to  criminal and civil enforcement actions.

44

Our business activities may require our employees to travel to and work in countries where there are high
security risks, which may result in employee death or injury, repatriation costs or other unforeseen costs.

Certain of our contracts may require our employees travel to and work in high-risk countries that are
undergoing political, social and economic upheavals resulting from war, civil unrest, criminal activity, acts
of terrorism or public health crises. For example, we currently have employees working in high security risk
countries such as Afghanistan. As a result, we risk loss of or injury to our employees and may be subject to
costs related to employee death or injury, repatriation or other unforeseen circumstances. We may choose
or be forced to leave a country with  little or no warning due to physical security risks.

Our failure to implement and comply with our safety program could adversely affect our operating results
or financial condition.

Our  safety  program  is  a  fundamental  element  of  our  overall  approach  to  risk  management,  and  the
implementation of the safety program is a significant issue in our dealings with our clients. We maintain an
enterprise-wide  group  of  health  and  safety  professionals  to  help  ensure  that  the  services  we  provide  are
delivered safely and in accordance with standard work processes. Unsafe job sites and office environments
have the potential to increase employee turnover, increase the cost of a project to our clients, expose us to
types  and  levels  of  risk  that  are  fundamentally  unacceptable,  and  raise  our  operating  costs.  The
implementation  of  our  safety  processes  and  procedures  are  monitored  by  various  agencies  and  rating
bureaus  and  may  be  evaluated  by  certain  clients  in  cases  in  which  safety  requirements  have  been
established in our contracts. Our failure to meet these requirements or our failure to properly implement
and comply with our safety program could result in reduced profitability or the loss of projects or clients,
and could have a material adverse effect on our business,  operating results or financial condition.

We may be precluded from providing certain services due to conflict of interest issues.

Many  of  our  clients  are  concerned  about  potential  or  actual  conflicts  of  interest  in  retaining
management  consultants.  U.S.  federal  government  agencies  have  formal  policies  against  continuing  or
awarding  contracts  that  would  create  actual  or  potential  conflicts  of  interest  with  other  activities  of  a
contractor. These policies, among other things, may prevent us from bidding for or performing government
contracts resulting from or relating to certain work we have performed. In addition, services performed for
a commercial or government client may create a conflict of interest that precludes or limits our ability to
obtain work from other public or private organizations. We have, on occasion, declined to bid on projects
due to conflict of interest issues.

If our reports and opinions are not in compliance with professional standards and other regulations, we
could be subject to monetary damages and penalties.

We  issue  reports  and  opinions  to  clients  based  on  our  professional  engineering  expertise,  as  well  as
our  other  professional  credentials.  Our  reports  and  opinions  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 in which the services are performed. In addition,
we  could  be  liable  to  third  parties  who  use  or  rely  upon  our  reports  or  opinions  even  if  we  are  not
contractually bound to those third parties. For example, if we deliver an inaccurate report or one that is not
in compliance with the relevant standards, and that report is made available to a third party, we could be
subject to third-party liability, resulting in monetary damages and  penalties.

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

Our  services  are  subject  to  numerous  U.S.  and  international  environmental  protection  laws  and
regulations that are complex and stringent. For example, we must comply with a number of U.S. federal
government  laws  that  strictly  regulate  the  handling,  removal,  treatment,  transportation  and  disposal  of
toxic  and  hazardous  substances.  Under  the  Comprehensive  Environmental  Response  Compensation  and

45

Liability  Act  of  1980,  as  amended  (‘‘CERCLA’’),  and  comparable  state  laws,  we  may  be  required  to
investigate  and  remediate  regulated  hazardous  materials.  CERCLA  and  comparable  state  laws  typically
impose  strict,  joint  and  several  liabilities  without  regard  to  whether  a  company  knew  of  or  caused  the
release  of  hazardous  substances.  The  liability  for  the  entire  cost  of  clean-up  could  be  imposed  upon  any
responsible party. Other principal federal environmental, health and safety laws affecting us include, but
are not limited to, the Resource Conversation and Recovery Act, the National Environmental Policy Act,
the  Clean  Air  Act,  the  Occupational  Safety  and  Health  Act,  the  Toxic  Substances  Control  Act  and  the
Superfund Amendments and Reauthorization Act. Our business operations may also be subject to similar
state  and  international  laws  relating  to  environmental  protection.  Further,  past  business  practices  at
companies  that  we  have  acquired  may  also  expose  us  to  future  unknown  environmental  liabilities.
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  clean-up
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.

Force  majeure  events,  including  natural  disasters  and  terrorist  actions  could  negatively  impact  the
economies in which we operate or disrupt our operations, which may affect our financial condition, results
of operations or cash flows.

Force majeure or extraordinary events beyond the control of the contracting parties, such as natural
and  man-made  disasters,  as  well  as  terrorist  actions,  could  negatively  impact  the  economies  in  which  we
operate  by  causing  the  closure  of  offices,  interrupting  projects  and  forcing  the  relocation  of  employees.
Further, despite our implementation of network security measures, our servers are vulnerable to computer
viruses,  break-ins  and  similar  disruptions  from  unauthorized  tampering  with  our  computer  systems.  We
typically  remain  obligated  to  perform  our  services  after  a  terrorist  action  or  natural  disaster  unless  the
contract  contains  a  force  majeure  clause  that  relieves  us  of  our  contractual  obligations  in  such  an
extraordinary event. If we are not able to react quickly to force majeure, our operations may be affected
significantly, which would have a negative impact on our financial condition, results of operations or cash
flows.

We  have  only  a  limited  ability  to  protect  our  intellectual  property  rights,  and  our  failure  to  protect  our
intellectual property rights could adversely affect  our competitive position.

Our  success  depends,  in  part,  upon  our  ability  to  protect  our  proprietary  information  and  other
intellectual  property.  We  rely  principally  on  trade  secrets  to  protect  much  of  our  intellectual  property
where we do not believe that patent or copyright protection is appropriate or obtainable. However, trade
secrets  are  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.  In
addition,  we  may  be  unable  to  detect  unauthorized  use  of  our  intellectual  property  or  otherwise  take
appropriate  steps  to  enforce  our  rights.  Failure  to  obtain  or  maintain  trade  secret  protection  could
adversely  affect  our  competitive  business  position.  In  addition,  if  we  are  unable  to  prevent  third  parties
from  infringing  or  misappropriating  our  trademarks  or  other  proprietary  information,  our  competitive
position could be adversely affected.

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

We  rely  heavily  on  computer,  information,  and  communications  technology  and  systems  to  operate.
From time to time, we experience system interruptions and delays. If we are unable to effectively deploy
software  and  hardware,  upgrade  our  systems  and  network  infrastructure,  and  take  steps  to  improve  and
protect our systems, systems operations  could  be  interrupted  or delayed.

Our  computer  and  communications  systems  and  operations  could  be  damaged  or  interrupted  by
natural disasters, telecommunications failures, acts of war or terrorism and similar events or disruptions. In

46

addition, we face the threat of unauthorized system access, computer hackers, computer viruses, malicious
code,  organized  cyber-attacks,  and  other  security  breaches  and  system  disruptions.  We  devote  significant
resources to the security of our computer systems, but they may still be vulnerable to threats. Anyone who
circumvents  security  measures  could  misappropriate  proprietary  information  or  cause  interruptions  or
malfunctions  in  system  operations.  As  a  result,  we  may  be  required  to  expend  significant  resources  to
protect against the threat of system disruptions and security breaches, or to alleviate problems caused by
disruptions and breaches.

Any  of  these  or  other  events  could  cause  system  interruption,  delays,  and  loss  of  critical  data  that
could  delay  or  prevent  operations,  and  could  have  a  material  adverse  effect  on  our  business,  financial
condition, results of operations and cash  flows, and could negatively  impact our clients.

Delaware law and our charter documents may impede or discourage a merger, takeover or other business
combination even if the business combination would have been in the best interests of our stockholders.

We  are  a  Delaware  corporation  and  the  anti-takeover  provisions  of  Delaware  law  impose  various
impediments to the ability of a third party to acquire control of us, even if a change in control would be
beneficial  to  our  stockholders.  In  addition,  our  Board  of  Directors  has  the  power,  without  stockholder
approval,  to  designate  the  terms  of  one  or  more  series  of  preferred  stock  and  issue  shares  of  preferred
stock, which could be used defensively if a takeover is threatened. Our incorporation under Delaware law,
the ability of our Board of Directors to create and issue a new series of preferred stock and provisions in
our certificate of incorporation and bylaws, such as those relating to advance notice of certain stockholder
proposals and nominations, could impede a merger, takeover or other business combination involving us
or discourage a potential acquirer from making a tender offer for our common stock, even if the business
combination would have been in the best  interests of our current stockholders.

Our stock price could become more volatile and stockholders’ investments could lose value.

In addition to the macroeconomic factors that have affected the prices of many securities generally, all
of  the  factors  discussed  in  this  section  could  affect  our  stock  price.  Our  common  stock  has  previously
experienced  substantial  price  volatility.  In  addition,  the  stock  market  has  experienced  extreme  price  and
volume  fluctuations  that  have  affected  the  market  price  of  many  companies  and  that  have  often  been
unrelated  to  the  operating  performance  of  these  companies.  The  overall  market  and  the  price  of  our
common stock may fluctuate greatly. The trading price of our common stock may be significantly affected
by various factors, including:

(cid:129) quarter-to-quarter  variations  in  our  financial  results,  including  revenue,  profits,  days  sales

outstanding, backlog, and other measures of financial performance or  financial condition;

(cid:129) our  announcements  or  our  competitors’  announcements  of  significant  events, 

including

acquisitions;

(cid:129) resolution of threatened or pending  litigation;

(cid:129) changes in investors’ and analysts’ perceptions of our business or any of our competitors’ businesses;

(cid:129) investors’ and analysts’ assessments of reports  prepared  or  conclusions reached by third parties;

(cid:129) changes in environmental legislation;

(cid:129) investors’  perceptions  of  our  performance  of  services  in  countries  in  which  the  U.S.  military  is

engaged, including Afghanistan;

(cid:129) broader market fluctuations; and

(cid:129) general economic or political conditions.

Volatility  in  the  financial  markets  could  cause  a  decline  in  our  stock  price,  which  could  trigger  an
impairment  of  the  goodwill  of  individual  reporting  units  that  could  be  material  to  our  consolidated

47

financial  statements.  A  significant  drop  in  the  price  of  our  stock  could  also  expose  us  to  the  risk  of
securities  class  action  lawsuits,  which  could  result  in  substantial  costs  and  divert  managements’  attention
and  resources,  which  could  adversely  affect  our  business.  Additionally,  volatility  or  a  lack  of  positive
performance in our stock price may adversely affect our ability to retain key employees, many of whom are
granted stock options and shares of restricted stock, the value of which is dependent on the performance of
our  stock price.

Item 2. Properties

At  fiscal  2012  year-end,  we  owned  three  facilities  located  in  the  United  States  that  are  used  for
operations.  Our  significant  lease  agreements  expire  at  various  dates  through  2021.  We  also  have  some
month-to-month  leases.  We  believe  that  our  current  facilities  are  adequate  for  the  operation  of  our
business and that suitable additional space in various local markets is available to accommodate any needs
that may arise.

The  following  table  summarizes  our  15  most  significant  leased  properties  based  on  the  amount  of

Item 4. Mine Safety Disclosures

Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the ‘‘Dodd-Frank
Act’’) required domestic mine operators to disclose violations and orders issued under the Federal Mine
Safety and Health Act of 1977 (the ‘‘Mine Act’’) by the U.S. Mine Safety and Health Administration. We
do not act as the owner of any mines but we may act as a mining operator as defined under the Mine Act
where  we  may  be  an  independent  contractor  performing  services  or  construction  at  such  a  mine.
Information concerning mine safety violations or other regulatory matters required by Section 1503(a) of
the Dodd-Frank Act and Item 104 Regulations  S-K  is included in Exhibit  95.

Item 7. Management’s Discussion and Analysis of  Financial Condition and Results of Operations

The  following  analysis  of  our  financial  condition  and  results  of  operations  should  be  read  in
conjunction with Part 1 of this report, as well as our consolidated financial statements and accompanying
notes  in  Item  8.  The  following  analysis  contains  forward-looking  statements  about  our  future  results  of
operations and expectations. Our actual results and the timing of events could differ materially from those
described  herein.  See  Part  1,  Item  1A,  ‘‘Risk  Factors’’  for  a  discussion  of  the  risks,  assumptions  and
uncertainties affecting these statements.

OVERVIEW OF RESULTS AND BUSINESS TRENDS

Management  review  of  fiscal  2012  and  outlook  for  the  future. On  an  overall  basis,  we  experienced
significant  improvement  in  our  fiscal  2012  operating  results  compared  with  fiscal  2011.  We  continued  to
focus on organic growth and the pursuit of strategic acquisitions that are expected to enhance our service
offerings  and  expand  our  geographic  presence.  Our  revenue  growth  resulted  primarily  from  industrial,
energy and environmental management projects for large multi-national companies. The growth was also
driven by demand for our water, environmental and infrastructure design services in Canada, Australia and
South  America,  primarily  for  mining  and  other  commodity-driven  businesses.  Our  overall  results  were
tempered by reduced revenue from our U.S. federal government programs that continued to slow in the
current year.

Impact  of  Recent  Business  Environment. Current  economic  conditions  have  been  somewhat  volatile
and there is increased uncertainty as to whether the U.S. or the global economy will grow modestly, remain
stagnant or enter a recession. The economic growth experienced in 2012 may or may not continue, or may
continue at a slower rate for an extended period of time. In addition, some economic conditions, such as
rates  of  spending  and  employment,  may  continue  to  be  weak.  Uncertainty  regarding  the  U.S.  federal
budget and taxes has added to the uncertainty regarding economic conditions generally. Those conditions
could be negatively impacted by the occurrence or threat of a so-called ‘‘fiscal cliff’’ consisting of, among
other  things,  mandatory  federal  budget  reductions,  or  sequestrations,  and  the  expiration  of  federal
individual tax rate reductions that become effective January 1, 2013. Concerns about the oncoming ‘‘fiscal
cliff’’  appear  to  be  restraining  business  owners  from  making  investment  commitments  needed  to  fund
future growth. With this uncertainty regarding the future, it is difficult to confidently predict the direction
in  which  the  U.S.  and  global  economies  are  headed.  Strong  economic  expansion  generally  benefits  our
business  while  a  tepid  economic  recovery  could  adversely  impact  the  demand  for  our  services.  It  is  not
possible to predict with certainty whether or when a recovery may occur, or what impact this would have on
our  business, results of operations, cash flows or financial condition.

International. Our  international  business  grew  11.3%  in  fiscal  2012  compared  to  fiscal  2011.  The
growth  was  driven  by  demand  for  our  water,  environmental  and  infrastructure  design  services  globally,
primarily from mining and other commodity-driven clients. We expect that our international business will
continue  its  growth  during  fiscal  2013  as  a  result  of  our  continued  expansion  in  Canada,  our  recent
expansion  into  Australia  and  South  America,  and  demand  for  our  services  from  broad-based  clients
worldwide.

U.S. Commercial. Our U.S. commercial business grew 24.3% in fiscal 2012 compared to fiscal 2011.
The  growth  was  broad-based  with  increased  revenue  from  industrial,  energy  and  environmental
management projects for large multi-national companies. Many of our largest U.S. commercial clients are
experiencing  higher  environmental  and  infrastructure  capital  spending  levels  following  a  period  of
budgetary  constraints  during  the  global  financial  crisis.  Therefore,  although  we  expect  some  economic
weakness  may  continue  in  certain  sectors  of  our  U.S.  commercial  business,  we  are  cautiously  optimistic
regarding  increased  spending  by  our  largest  U.S.  commercial  clients.  As  such,  we  expect  that  our  U.S.
commercial  business  will  continue  its  growth  in  fiscal  2013.  Our  U.S.  commercial  clients  typically  react

52

rapidly to economic change. Accordingly, if the U.S. economy experiences a slowdown in fiscal 2013, we
would expect our U.S. commercial outlook to change  accordingly.

U.S.  Federal  Government. Our  U.S.  federal  government  business  declined  9.6%  in  fiscal  2012
compared to fiscal 2011. This decline resulted primarily from lower revenue on DoD programs, principally
from  the  wind-down  of  several  large  New  Orleans  hurricane  protection  and  environmental  remediation
programs for USACE. The decline was partially offset by revenue growth from international development
services  for  the  DoS,  and  from  our  front-end  water,  environmental  and  infrastructure  engineering  and
design  services  for  other  federal  agencies.  During  periods  of  economic  volatility,  our  U.S.  federal
government  clients  have  historically  been  the  most  stable  and  predictable.  However,  due  to  the  U.S.
federal budget uncertainties described  above, we  remain cautious.

U.S. State and Local Government. Our U.S. state and local government business increased 13.0% in
fiscal 2012 compared to fiscal 2011. The growth was driven by increased revenue from essential programs.
Many state and local government agencies continue to face economic challenges, including budget deficits
and difficult cost cutting decisions. Simultaneously, states are facing major long-term infrastructure needs,
including the need for maintenance, repair and upgrading of existing critical infrastructure and the need to
build  new  facilities.  The  funding  risks  associated  with  our  U.S.  state  and  local  government  programs  are
partially mitigated by legal requirements that drive some of these programs, such as regulatory-mandated
consent  decrees.  As  a  result,  some  programs  will  generally  progress  despite  budget  pressures  as
demonstrated by the growth in fiscal 2012. Although we anticipate that many state and local government
agencies will continue to face economic challenges, we expect our U.S. state and local government business
to continue its current growth rate in fiscal 2013 compared to fiscal 2012 because of our focus on essential
programs.

Reorganization  of  Operations. Our  operating  results  for  fiscal  2012  reflect  the  execution  of  a
reorganization of our operations initiated in the fourth quarter of fiscal 2012 to improve future growth and
profitability. These activities included the consolidation and realignment of certain operating activities to
improve  organizational  effectiveness  and  achieve  efficiencies  in  our  segment  management.  We  also
decided to wind down certain unprofitable business  activities.

During  the  implementation  of  this  reorganization  plan,  we  incurred  additional  costs  in  the  fourth
quarter  of  fiscal  2012,  including  discretionary  compensation-related  costs  for  severance  and  employee
retention. In addition, we recorded charges for lease exit costs, and fixed asset and other long-lived asset
impairments primarily associated with office space reductions and relocations. We also incurred contract
and  other  losses  to  wind  down  certain  India-based  activities  that  are  no  longer  supported  by  our
reorganized business.

Specifically, this reorganization included the elimination of the EAS reportable segment effective at
the  beginning  of  fiscal  2013.  The  operating  activities  previously  reported  in  this  segment  have  been
realigned with operations with similar client types, project types and financial metrics in the ECS and TSS
segments.  In  anticipation  of  these  organizational  changes,  staffing  and  office  space  were  reduced  during
the fourth quarter of fiscal 2012 to reflect a more effective and efficient management structure over our
global  operations.  We  also  revised  the  assumptions  related  to  future  operating  results  in  our  goodwill
valuations  consistent  with  the  operational  review  that  supported  the  reorganization.  During  this
evaluation,  we  identified  one  small  reporting  unit  in  our  EAS  segment  with  impairment.  This  operating
unit reported lower than planned operating income during the fourth quarter of fiscal 2012 and projected
future  operating  losses  and  negative  cash  flows,  which  caused  a  non-cash  impairment  charge  of
$0.9 million, representing all of the goodwill in this reporting unit in  the fourth  quarter  of fiscal 2012.

Although we anticipate that these consolidation and reorganization efforts will continue into the first
half  of  fiscal  2013,  we  do  not  expect  these  activities  to  have  a  further  material  effect  on  our  results  of

53

operations. Conversely, these actions are expected to modestly improve our operating results in fiscal 2013
through lower overhead costs and increased effectiveness in growing our operations organically.

(1) We  believe  that  the  presentation  of  ‘‘Revenue,  net  of  subcontractor  costs,’’  a  non-GAAP  financial  measure,
enhances  investors’  ability  to  analyze  our  business  trends  and  performance  because  it  substantially  measures  the
work  performed  by  our  employees.  In  the  course  of  providing  services,  we  routinely  subcontract  various  services
and,  under  certain  USAID  programs,  issue  grants.  Generally,  these  subcontractor  costs  and  grants  are  passed
through to our clients and, in accordance with GAAP and industry practice, are included in our revenue when it is
our  contractual  responsibility  to  procure  or  manage  these  activities.  The  grants  are  included  as  part  of  our
subcontractor  costs.  Because  subcontractor  services  can  vary  significantly  from  project  to  project  and  period  to
period,  changes  in  revenue  may  not  necessarily  be  indicative  of  our  business  trends.  Accordingly,  we  segregate
subcontractor costs from revenue to promote a better understanding of our business by evaluating revenue exclusive
of costs associated with external service providers.

Overall, our fiscal 2012 operating results improved significantly compared with fiscal 2011. Revenue
and revenue, net of subcontractor costs, increased $137.9 million and $229.7 million, respectively, in fiscal
2012 compared to the prior year. The growth was driven by strong results in our U.S. commercial business,
the  continued  expansion  of  our  international  business,  and  contributions  from  acquisitions  completed
during  fiscal  2012  and  2011.  To  a  lesser  extent,  our  U.S.  state  and  local  government  market  also

54

contributed  to  the  growth.  Our  revenue,  net  of  subcontractor  costs,  in  our  U.S.  federal  government
business  increased  slightly  versus  last  year;  however,  the  related  revenue  declined  due  to  decreased
revenue  from  certain  construction  management  projects  for  the  DoD  that  had  a  high  level  of
subcontracting activities. As a result, our overall revenue, net of subcontractor costs, grew at a higher rate
than revenue compared to last year.

Revenue  and  revenue,  net  of  subcontractor  costs,  for  our  U.S.  commercial  business  increased
$140.7  million  and  $75.2  million,  respectively,  in  fiscal  2012  compared  to  fiscal  2011.  The  growth  was
experienced  across  all  of  our  reportable  segments,  and  was  primarily  attributable  to  increased  revenue
from  industrial,  energy  and  environmental  management  projects  for  large  multi-national  companies.
Revenue  and  revenue,  net  of  subcontractor  costs,  for  our  international  business  increased  $67.7  million
and $112.1 million, respectively, in fiscal 2012 versus the prior year. The growth was driven by increased
activity  on  our  water,  environmental  and  infrastructure  design  projects  in  Canada,  Australia  and  South
America,  primarily  for  mining  and  other  commodity-driven  businesses.  Additionally,  revenue,  net  of
subcontractor costs, grew at a faster pace than revenue due to increased self-performance on international
projects  in  fiscal  2012.  Revenue  and  revenue,  net  of  subcontractor  costs,  for  fiscal  2012  included
contributions  from  acquisitions  totaling  $133.2  million  and  $122.3  million,  respectively.  Approximately
one-third of these amounts were contributed by our international acquisitions. Our overall revenue growth
was  partially  offset  by  declines  in  revenue  and  revenue,  net  of  subcontractor  costs,  on  DoD  programs
totaling  $135.4  million  and  $49.6  million,  respectively,  in  fiscal  2012  compared  to  fiscal  2011.  These
reductions  resulted  primarily  from  the  wind-down  of  several  large  New  Orleans  hurricane  protection
projects for USACE and environmental  remediation programs for the DoD.

Operating income increased 13.6% in fiscal 2012 compared to fiscal 2011 primarily due to growth in
our revenue and revenue, net of subcontractor costs. In addition, operating income increased at a higher
rate  than  revenue  due  to  better  project  performance  in  fiscal  2012.  In  fiscal  2011,  operating  income  was
reduced  by  contract  costs  incurred  for  project  overruns  of  $21.0  million  on  several  fixed-priced
construction management projects in the RCM segment, and on an international development program in
the  TSS  segment.  These  fiscal  2011  items  were  partially  mitigated  by  a  $10.6  million  government
performance-based  incentive  award  fee  on  a  large  environmental  remediation  program  in  the  RCM
segment and a $2.0 million net favorable  project settlement  in the EAS segment.

In the fourth quarter of fiscal 2012, operating income was adversely impacted by $16.9 million of costs
related  to  the  reorganization  of  our  operations  as  described  above  in  the  ‘‘Overview  of  Results  and
Business  Trends.’’  These  costs  included  $6.4  million  of  compensation-related  expenses  for  severance  and
employee retention. In addition, we recorded $4.4 million of lease exit costs, fixed asset write-downs and
other  long-lived  asset  impairments  associated  with  office  space  reductions  and  relocations.  Further,  we
incurred  operational  losses  of  $5.2  million  for  winding  down  certain  India-based  activities  that  are  no
longer  supported  by  our  reorganized  business  model.  We  also  identified  one  small  reporting  unit  in  the
EAS segment in which goodwill was impaired. This reporting unit realized lower than planned operating
income  during  the  fourth  quarter  of  fiscal  2012,  and  projected  future  operating  losses  and  negative  cash
flows that resulted in a $0.9 million non-cash goodwill impairment charge. Operating income in fiscal 2012
also  included  net  gains  of  $19.2  million  related  to  changes  in  the  estimated  fair  value  of  our  contingent
earn-out  liabilities  during  fiscal  2012,  $17.3  million  of  which  were  recognized  in  the  fourth  quarter,
compared to $1.8 million during fiscal 2011.

The $17.3 million net decrease in our contingent consideration liability in the fourth quarter of fiscal
2012 included $12.5 million related to our determination in that quarter that one of our acquisitions in the
TSS segment would not achieve the operating income we previously expected for the earn-out period. The
remaining fourth quarter net earn-out adjustments primarily related to several of our recent acquisitions in
the ECS segment for which the earn-out periods  concluded in the fourth quarter of fiscal  2012.

55

Income tax expense increased due to higher pre-tax income. Our effective tax rate for fiscal 2012 was
34.9% compared to 33.8% for fiscal 2011. The prior-year tax rate benefitted from the extension of R&E
credits. There was a $1.2 million benefit from R&E credits for the last nine months of fiscal 2010 that was
recorded in the first quarter of fiscal 2011. With the expiration of the R&E credits on December 31, 2011,
we have not estimated a benefit from these  credits  beyond the expiration date.

Revenue  and  revenue,  net  of  subcontractor  costs,  increased  $106.5  million  and  $97.6  million,
respectively,  in  fiscal  2012  compared  to  fiscal  2011.  The  growth  was  primarily  driven  by  demand  for  our
water,  environmental  and  infrastructure  design  services  globally,  and  our  continued  international
expansion  into  Canada,  Australia  and  South  America.  In  fiscal  2012,  recent  acquisitions  contributed
$40.5 million and $38.8 million to revenue  and  revenue, net  of subcontractor costs, respectively.

Despite the growth in revenue and revenue, net of subcontractor costs, operating income was stable
compared to fiscal 2011. Seasonal inclement weather conditions at our larger Canadian operations during
the  first  half  of  fiscal  2012  contributed  to  the  lower  operating  margin.  The  adverse  working  conditions
resulted in lower staff utilization on projects and higher indirect expenses. In addition, operating income
was  negatively  impacted  by  $1.1  million  of  severance  and  other  discretionary  compensation-related  costs
associated  with  reorganization  in  the  fourth  quarter  of  fiscal  2012.  Further,  the  wind-down  of  several
high-profit water and mining-related projects had a negative effect in comparison to fiscal 2012 operating
income.

Revenue  and  revenue,  net  of  subcontractor  costs,  increased  $52.7  million  and  $89.9  million,
respectively, in fiscal 2012 compared to fiscal 2011. This growth was primarily driven by the expansion of
international development services provided to the DoS. Revenue and revenue, net of subcontractor costs,
from DoS services increased $80.7 million and $71.5 million, respectively, this fiscal year compared to fiscal
2011.  Virtually  all  of  the  increase  in  DoS  revenue  resulted  from  an  acquisition  completed  in  the  fourth
quarter of fiscal 2011. An increase in U.S. commercial business contributed $20.0 million and $19.1 million
of  additional  revenue  and  revenue,  net  of  subcontractor  costs,  compared  to  fiscal  2011.  An  acquisition
completed  in  fiscal  2012  contributed  approximately  one-half  of  this  commercial  growth.  Revenue,  net  of
subcontractor  costs,  grew  at  a  faster  rate  than  revenue  due  to  reduced  workload  on,  and  completion  of,
certain USAID and EPA programs that had a high  level of  subcontracting activities  in fiscal 2011.

Operating  income  increased  $8.3  million  in  fiscal  2012  compared  to  fiscal  2011  due  to  increased
revenue, net of subcontractor costs. Acquisitions completed in the fourth quarter of fiscal 2011 and during
fiscal 2012 contributed $6.7 million to the operating income increase. Further, fiscal 2011 operating income
was  negatively  affected  by  $1.2  million  of  contract  costs  overruns  on  an  international  development
program.  The  overall  increase  was  partially  offset  by  $2.2  million  of  severance  and  other  discretionary
compensation-related costs associated with our reorganization in the fourth quarter of fiscal  2012.

Revenue  increased  $10.6  million  in  fiscal  2012  compared  to  fiscal  2011  due  to  contributions  from
design-build projects for U.S. government clients. The growth also resulted from demand for our building
and facility design services from several large U.S. commercial clients and increased workload on multiple
international  development  projects  for  USAID.  The  growth  was  partially  offset  by  reduced  activity  on
certain  infrastructure  design  projects  for  U.S.  government  clients  in  fiscal  2012.  Despite  the  revenue
growth, revenue, net of subcontractor costs, declined $5.1 million compared to last year due primarily to
increased  subcontracting  activities  on  several  large  design-build  projects  that  transitioned  into  the
construction management phase during fiscal 2012.

Operating income declined $10.1 million in fiscal 2012 compared to fiscal 2011 due partially to lower
revenue,  net  of  subcontractor  costs.  In  addition,  $2.1  million  of  severance  and  other  discretionary
compensation-related  costs  associated  with  our  reorganization  in  the  fourth  quarter  of  fiscal  2012
contributed to the decrease. This segment also incurred $5.2 million of contract and other losses for certain
India-based  activities. Our  reorganized  business  model,  with  the  elimination  of  the  EAS  segment  at  the
beginning  of  fiscal  2013,  no  longer  supports  these  operations.  Further,  fiscal  2011  operating  income
benefitted from a favorable $2.0 million net project settlement on a U.S. commercial infrastructure project.

Revenue  and  revenue,  net  of  subcontractor  costs,  increased  $17.3  million  and  $47.4  million,
respectively, in fiscal 2012 compared to fiscal 2011. Our U.S. commercial business grew $96.5 million and
$57.2 million in revenue and revenue, net of subcontractor costs, respectively, due primarily to expanded
programs in our mining and energy businesses. Our U.S. state and local government business contributed
$38.5  million  and  $31.4  million  of  revenue  and  revenue,  net  of  subcontractor  costs,  respectively,  due  to
several large infrastructure projects. The growth was partially offset by a revenue decline of $107.6 million,
and  a  corresponding  $33.2  million  decrease  in  revenue,  net  of  subcontractor  costs,  resulting  from  the
wind-down  of  several  large  New  Orleans  hurricane  protection  projects  for  USACE  and  environmental
remediation programs for the DoD at the end of fiscal 2011. The decline in revenue was larger than the
related  decline  in  revenue,  net  of  subcontractor  costs,  because  the  USACE  and  DoD  projects  had  a
relatively high level of subcontractor costs.

Operating income increased $9.2 million due partially to the increase in revenue, net of subcontractor
costs,  compared  to  fiscal  2011.  In  addition,  fiscal  2011  operating  income  was  adversely  impacted  by
$20.0  million  of  contract  cost  overruns  on  several  fixed-price  infrastructure  and  energy  projects  and  a
$1.3 million charge for lease exit costs. These fiscal 2011 items were partially mitigated by $10.6 million of
government performance-based incentive award fees on a large environmental remediation program with
the DoD. In fiscal 2012, we benefitted from $2.9 million of gains related to the settlement of project claims
and change orders partially offset by $2.4  million of project-related losses.

(1) We  believe  that  the  presentation  of  ‘‘Revenue,  net  of  subcontractor  costs,’’  a  non-GAAP  financial  measure,
enhances  investors’  ability  to  analyze  our  business  trends  and  performance  because  it  substantially  measures  the
work  performed  by  our  employees.  In  the  course  of  providing  services,  we  routinely  subcontract  various  services
and,  under  certain  USAID  programs,  issue  grants.  Generally,  these  subcontractor  costs  and  grants  are  passed
through to our clients and, in accordance with GAAP and industry practice, are included in our revenue when it is
our  contractual  responsibility  to  procure  or  manage  these  activities.  The  grants  are  included  as  part  of  our
subcontractor  costs.  Because  subcontractor  services  can  vary  significantly  from  project  to  project  and  period  to
period,  changes  in  revenue  may  not  necessarily  be  indicative  of  our  business  trends.  Accordingly,  we  segregate
subcontractor costs from revenue to promote a better understanding of our business by evaluating revenue exclusive
of costs associated with external service providers.

Revenue  increased  significantly  in  fiscal  2011  compared  to  fiscal  2010.  We  experienced  increased
demand for our water, environmental, infrastructure design and construction management services in the
mining  and  energy  markets  worldwide.  The  recent  acquisitions,  primarily  in  Canada,  contributed
$380.1  million  and  $323.9  million  of  additional  revenue  and  revenue,  net  of  subcontractor  costs,
respectively. Further, our revenue increased from our front-end water, environmental, and infrastructure
engineering  and  design  services  for  certain  U.S.  federal  government  clients  including  the  EPA,  FAA,
National  Science  Foundation  (‘‘NSF’’),  IBWC,  GSA,  U.S.  Department  of  Agriculture  (‘‘DOA’’)  and
various military branches of the DoD. These revenue increases were largely offset by a decline in the U.S.
federal  government  business  due  primarily  to  the  wind-down  of  certain  large  construction  management
projects  for  the  USACE  and  the  DOE,  and  delays  on  new  awards  for  certain  large  construction
management  projects  in  the  U.S.  and  abroad.  Our  state  and  local  government  sector  also  experienced  a

59

revenue  decrease  as  a  result  of  continuing  weakness  in  the  economy,  as  well  as  reduced  activity  on  a
transportation infrastructure and municipal landfill design projects. Overall, revenue, net of subcontractor
costs,  grew  at  a  higher  rate  than  revenue.  This  resulted  from  the  increase  in  self-performed  work  in  the
energy  sector  and  reduced  revenue  from  construction  management  projects,  which  typically  have  higher
subcontracting activities. In the fourth quarter of fiscal 2010, we recognized approximately $45 million and
$30  million  in  additional  revenue  and  revenue,  net  of  subcontractor  costs,  respectively,  as  result  of  the
53-week year in fiscal 2010 compared to the  52-week year in  fiscal  2011.

Operating income increased as a result of business growth. Additionally, operating income benefited
from the recognition of government incentive award fees on a large environmental remediation program
and favorable project close-outs on energy and construction management projects. Operating income also
increased due to favorable claim settlements and lower bad debt expense on commercial projects. Further,
we recognized a gain of $1.8 million in fiscal 2011 from a net reduction of contingent earn-out liabilities.
The  operating  income  increase  was  partially  offset  by  additional  contract  costs  incurred  for  project
overruns  on  several  fixed-price  construction  projects  and  a  large  energy  project.  Further,  we  recognized
additional selling, general and administrative (‘‘SG&A’’) costs due to higher charges in fiscal 2011 related
to our recent acquisitions including $15.3 million of amortization expense for intangible assets, $1.5 million
of foreign currency exchange loss and  other  acquisition  costs compared to  fiscal 2010.

Net interest expense grew as a result of increased borrowings on our credit facility for acquisitions and
additional  imputed  interest  costs  recognized  for  long-term  contingent  earn-out  liabilities  associated  with
our  fiscal 2010 and 2011 acquisitions.

Income tax expense increased due to higher pre-tax income. Our effective tax rate for fiscal 2011 was
33.8% compared to 37.6% for fiscal 2010. The lower effective tax rate resulted from our continued foreign
expansion  during  fiscal  2011  and  the  extension  of  R&E  credits.  In  the  first  quarter  of  fiscal  2011,  we
recorded  a $1.2 million benefit from  R&E credits for the  last nine months  of fiscal 2010.

Net  income  attributable  to  noncontrolling  interests  related  primarily  to  the  consolidated  joint
ventures  associated  with  our  Canadian  acquisitions.  Net  income  attributable  to  Tetra  Tech  grew  for  the
reasons described above.

Revenue  increased  significantly  in  fiscal  2011  compared  to  fiscal  2010.  The  recent  acquisitions,
primarily in Canada, contributed $328.2 million and $300.4 million of additional revenue and revenue, net
of  subcontractor  costs,  respectively.  Excluding  the  effect  of  acquisitions,  the  growth  was  driven  by
increased  demand  for  our  water,  environmental  and  infrastructure  design  services  for  mining  clients

60

worldwide. To a lesser extent, the growth resulted from increased activity on EPA, FAA, NSF, IBWC and
other U.S. federal government projects. The overall growth was partially offset by a wind-down on certain
DoD and DOE projects, reduced activity on a large municipal landfill design project, and weakness in the
state  and  local  government  business.  Revenue,  net  of  subcontractor  costs,  grew  at  a  faster  pace  than
revenue due to the high level of self-performed  work in our international business.

Operating  income  increased  due  predominantly  to  revenue  growth.  As  a  percentage  of  revenue,
operating income increased due to improved project execution and higher profit margins on international
projects.

Revenue increased in fiscal 2011 compared to fiscal 2010. An acquisition in the fourth quarter of fiscal
2010 contributed $51.9 million and $23.6 million to fiscal 2011 revenue and revenue, net of subcontractor
costs, respectively. Excluding the effect of this acquisition, revenue declined due to reduced workload on
DoD and other U.S. federal government projects, partially offset by growth in the commercial, and state
and local government sectors. Revenue, net of subcontractor costs, grew at a slower pace than revenue due
to  a  change  in  contract  mix  on  USAID  projects,  and  a  high  level  of  subcontracting  activities  at  the
aforementioned acquired company and on certain EPA programs.

Operating  income  increased  due  to  revenue  growth,  reduced  overhead  costs  and  favorable  project
close-outs  in  fiscal  2011.  The  increase  was  partially  offset  by  $1.2  million  of  additional  contract  costs
incurred for project overruns in the second quarter of fiscal 2011. As a percentage of revenue, operating
income increased compared to prior year for the reasons described above and better project performance.

Revenue growth was driven by demand for our building and facility design services from several large
commercial  clients,  and  increased  workload  on  international  development  projects  for  the  U.S.  federal
government.  Additionally,  the  growth  resulted  from  increased  activity  on  a  few  large  water  and
transportation  infrastructure  projects  for  state  and  local  government  clients.  The  revenue  growth  was
partially offset by the wind-down of several design projects overseas and the overall continued weakness in
the state and local government markets. Revenue, net of subcontractor costs, grew at a slower pace than
revenue  due  primarily  to  increased  subcontracting  activities  on  building  and  facility  design  and
international development projects.

Operating  income  increased  due  to  revenue  growth,  a  reduction  in  facility  costs  that  resulted  from
prior-year office consolidations, and lower provisions for losses on accounts receivable as a result of cash
collections. Additionally, operating income benefited from a favorable claim settlement of $2.3 million and
favorable project close-outs. In fiscal 2010, operating income was reduced by a $3.1 million provision for
losses on accounts receivable on certain  commercial development  and infrastructure projects.

Revenue  declined  in  fiscal  2011compared  to  fiscal  2010.  This  decline  was  due  primarily  to  the
wind-down  of  certain  large  construction  management  projects  for  USACE,  inclement  weather  in  the
northeast U.S., and reduced activity on DOE water and transportation infrastructure projects. Further, the
decline resulted from reduced activity on a large transportation infrastructure project for a state and local
government client. The decline was partially mitigated by strength in our energy markets worldwide, and
increased  activity  on  mining  and  certain  U.S.  federal  government  projects  for  GSA,  DOA  and  various

62

military branches of the DoD. Revenue, net of subcontractor costs, declined at a slower pace than revenue
due  to  increased  self-performed  work  on  energy  projects  and  reduced  revenue  from  construction
management projects, which typically have higher subcontracting activities.

Operating  income  was  adversely  impacted  by  the  aforementioned  revenue  decline,  and  lower  profit
rates on certain U.S. federal government and commercial construction management projects as a result of
competitive pricing pressure and a lower realization on contract change orders and claims. In addition, we
recognized  approximately  $20  million  of  cost  overruns  on  several  fixed-price  construction  and  energy
projects. In the fourth quarter of fiscal 2011, we incurred an additional $1.3 million charge for lease exit
costs  associated  with  our  effort  to  further  reduce  overhead  costs  and  consolidate  certain  facilities  in
response to the aforementioned revenue decline. The operating income decline was partially mitigated by
the recognition of $10.6 million in government incentive award fees on a large environmental remediation
program  with  the  DoD,  favorable  project  close-outs  related  to  energy  and  construction  management
projects and a favorable legal claim settlement  in fiscal 2011.

Non-GAAP Financial Measures

We are providing certain non-GAAP financial measures that we believe are appropriate measures for
evaluating  the  operating  performance  of  our  business.  These  non-GAAP  measures  should  not  be
considered in isolation from, and are not intended to represent an alternative measure of, operating results
or cash flows from operating activities, as  determined in  accordance with U.S. GAAP.

EBITDA  represents  net  income  attributable  to  Tetra  Tech  plus  net  interest  expense,  income  taxes,
depreciation  and  amortization.  We  believe  EBITDA  is  a  useful  representation  of  our  operating
performance  because  of  significant  amounts  of  acquisition-related  non-cash  amortization  expense,  which
can fluctuate significantly depending on the timing, nature and size of our business acquisitions. Revenue,
net  of  subcontractor  costs,  is  defined  as  revenue  less  subcontractor  costs.  For  more  information,  see  the
‘‘Consolidated Results of Operations’’ discussion above. EBITDA and revenue, net of subcontractor costs,
as we calculate them, may not be comparable to similarly titled measures employed by other companies.

The  following  is  a  reconciliation  of  EBITDA  to  net  income  attributable  to  Tetra  Tech  as  well  as

revenue, net of subcontractor costs, for fiscal  2010 through 2012:

FINANCIAL CONDITION, LIQUIDITY  AND CAPITAL RESOURCES

Capital  Requirements. Our  capital  requirements  are  to  fund  working  capital  needs,  capital
expenditures and debt service requirements, as well as to fund acquisitions and earn-out obligations from
prior acquisitions. We believe that our cash balances, operating cash flow and available borrowing under
our credit agreement (the ‘‘Credit Agreement’’) will be sufficient to meet our capital requirements for at
least the next 12 months.

We utilize a variety of tax planning and financing strategies to manage our worldwide cash and deploy
funds to locations where they are needed. We also indefinitely reinvest a significant portion of our foreign
earnings, and our current plans do not demonstrate a need to repatriate these earnings. Should we require
additional  capital  in  the  U.S.,  we  may  elect  to  repatriate  indefinitely  reinvested  foreign  funds  or  raise
capital in the U.S. through debt. If we were to repatriate indefinitely reinvested foreign funds, we would be
required to accrue and pay additional  U.S. taxes less  applicable  foreign tax  credits.

Operating Activities. For fiscal 2012, net cash provided by operating activities was $158.0 million, an
increase of $26.4 million compared to fiscal 2011. The increase resulted from higher EBITDA, and lower
prepaid expenses and other assets as a result of various cash settlements related to project claims in fiscal
2012. Further, the increase was driven by favorable changes in accounts payable and accrued compensation
caused  by  the  timing  of  payments  to  vendors,  subcontractors  and  employees.  The  overall  increase  was
partially offset by an increase in a net accounts receivable balance due primarily to revenue growth in the
fourth quarter of fiscal 2012 compared  to  the same quarter last year.

Investing Activities. For fiscal 2012, net cash used in investing activities was $79.8 million, a decrease
of  $214.0  million  compared  to  fiscal  2011.  The  decrease  resulted  primarily  from  reduced  investments  in
business acquisitions in fiscal 2012 compared to fiscal 2011.

Financing Activities. For fiscal 2012, net cash used in financing activities was $67.4 million compared
to  net  cash  provided  by  financing  activities  of  $31.4  in  fiscal  2011.  We  made  net  payments  on  long-term
debt and other borrowings of $68.1 million in fiscal 2012 compared to net borrowings of $24.6 million in
fiscal  2011.  In  fiscal  2012,  we  made  $18.1  million  of  contingent  earn-out  payments  related  to  prior-year
acquisitions, which were initially accrued at their respective acquisition dates. We received a $9.8 million
increase in net proceeds from the exercise of stock  options  in fiscal 2012.

Debt  Financing. Under  our  Credit  Agreement,  our  revolving  credit  facility  (‘‘Facility’’)  is  a
$460 million, five-year facility that matures on March 28, 2016. The Facility includes a $200 million sublimit
for the issuance of standby letters of credit and a $100 million sublimit for multicurrency borrowings and
letters  of  credit.  At  September  30,  2012,  we  had  $79.2  million  in  borrowings  under  the  Facility  at  a
weighted-average interest rate of 2.15% per annum. Additionally, we had $24.3 million in standby letters of
credit, of which $5.3 million was issued outside of the Facility, and we had $14.2 million in multicurrency
borrowings under the Facility. At September 30, 2012, we had $361.8 million of available credit under the
Facility all of which could be borrowed  without being in violation of our debt covenants.

The  Credit  Agreement  contains  certain  financial  and  various  other  affirmative  and  negative
covenants. They include, among others, a maximum consolidated leverage ratio of 2.5x (total funded debt/
EBITDA, as defined in the Credit Agreement) and a minimum consolidated fixed charge coverage ratio of
1.25x  (EBITDA,  as  defined  in  the  Credit  Agreement  minus  capital  expenditures/cash  interest  plus  taxes
plus principal payments of indebtedness including capital leases, notes and post-acquisition payments). At
September  30,  2012,  we  were  in  compliance  with  these  covenants  with  a  consolidated  leverage  ratio  of
0.72x and a consolidated fixed charge coverage ratio  of 1.94x. The  Facility is guaranteed by our material
subsidiaries  and  certain  additional  designated  subsidiaries.  Borrowings  under  the  Credit  Agreement  are
collateralized by our accounts receivable, the stock of  our subsidiaries and intercompany loans.

Inflation. We believe our operations have not been, and, in the foreseeable future, are not expected
to  be,  materially  adversely  affected  by  inflation  or  changing  prices  due  to  the  average  duration  of  our
projects and our ability to negotiate prices as  contracts  end  and new  contracts begin.

earn-out obligations for acquisitions consummated prior to fiscal 2010 are approximately $3.0 million, which would be paid in
fiscal  2013, if earned.
Represents  liabilities  for  unrecognized  tax  benefits  related  to  uncertain  tax  positions,  excluding  amounts  related  primarily  to
outstanding refund claims. We are unable to reasonably predict the timing of tax settlements, as tax audits can involve complex
issues and the resolution of those issues may span multiple years, particularly if subject to negotiation or litigation. For more
information, see Note 7, ‘‘Income Taxes’’ of the ‘‘Notes to Consolidated Financial Statements’’ included in Item 8.

Off-Balance Sheet Arrangements

In the ordinary course of business, we may use off-balance sheet arrangements if we believe that such
an arrangement would be an efficient way to lower our cost of capital or help us manage the overall risks of
our business operations. We do not believe that such arrangements have had a material adverse effect on
our  financial position or our results of operations.

The following is a summary of our off-balance sheet arrangements:

(cid:129) Letters  of  credit  and  bank  guarantees  are  used  primarily  to  support  project  performance  and
insurance  programs.  We  are  required  to  reimburse  the  issuers  of  letters  of  credit  and  bank
guarantees for any payments they make under the outstanding letters of credit or bank guarantees.
Our  Credit  Agreement  and  additional  letter  of  credit  facilities  cover  the  issuance  of  our  standby
letters of credit and bank guarantees and are critical for our normal operations. If we default on the
Credit  Agreement  or  additional  credit  facilities,  our  ability  to  issue  or  renew  standby  letters  of
credit  and  bank  guarantees  would  impair  our  ability  to  maintain  normal  operations.  As  of
September 30, 2012, we had $19.0 million in standby letters of credit outstanding under our Credit
Agreement and $5.3 million in standby letters of credit outstanding under our additional letter of
credit facilities.

(cid:129) We  have  guaranteed  a  bank  overdraft  facility  at  one  of  our  foreign  affiliates  in  the  amount  of

$2.0 million as of September 30, 2012.

(cid:129) From  time  to  time,  we  provide  guarantees  and  indemnifications  related  to  our  services.  If  our
services  under  a  guaranteed  or  indemnified  project  are  later  determined  to  have  resulted  in  a
material defect or other material deficiency, then we may be responsible for monetary damages or
other  legal  remedies.  When  sufficient  information  about  claims  on  guaranteed  or  indemnified

65

projects is available and monetary damages or other costs or losses are determined to be probable,
we recognize such guaranteed losses.

(cid:129) In  the  ordinary  course  of  business,  we  enter  into  various  agreements  as  part  of  certain
unconsolidated  subsidiaries,  joint  ventures,  and  other  jointly  executed  contracts  where  we  are
jointly  and  severally  liable.  We  enter  into  these  agreements  primarily  to  support  the  project
execution  commitments  of  these  entities.  The  potential  payment  amount  of  an  outstanding
performance guarantee is typically the remaining cost of work to be performed by or on behalf of
third  parties  under  engineering  and  construction  contracts.  However,  we  are  not  able  to  estimate
other amounts that may be required to be paid in excess of estimated costs to complete contracts
and,  accordingly,  the  total  potential  payment  amount  under  our  outstanding  performance
guarantees  cannot  be  estimated.  For  cost-plus  contracts,  amounts  that  may  become  payable
pursuant  to  guarantee  provisions  are  normally  recoverable  from  the  client  for  work  performed
under the contract. For lump sum or fixed-price contracts, this amount is the cost to complete the
contracted  work  less  amounts  remaining  to  be  billed  to  the  client  under  the  contract.  Remaining
billable  amounts  could  be  greater  or  less  than  the  cost  to  complete.  In  those  cases  where  costs
exceed the remaining amounts payable under the contract, we may have recourse to third parties,
such as owners, co-venturers, subcontractors  or vendors,  for claims.

(cid:129) In  the  ordinary  course  of  business,  our  clients  may  request  that  we  obtain  surety  bonds  in
connection  with  contract  performance  obligations  that  are  not  required  to  be  recorded  in  our
consolidated balance sheets. We are obligated to reimburse the issuer of our surety bonds for any
payments  made  thereunder.  Each  of  our  commitments  under  performance  bonds  generally  ends
concurrently with the expiration of our related  contractual obligation.

CRITICAL ACCOUNTING POLICIES  AND  ESTIMATES

The  preparation  of  our  financial  statements  in  conformity  with  U.S.  GAAP  requires  us  to  make
estimates and assumptions in the application of certain accounting policies that affect amounts reported in
our  consolidated  financial  statements  and  accompanying  footnotes  included  in  Item  8  of  this  report.  In
order to understand better the changes that may occur to our financial condition, results of operations and
cash  flows,  readers  should  be  aware  of  the  critical  accounting  policies  we  apply  and  estimates  we  use  in
preparing  our  consolidated  financial  statements.  Although  such  estimates  and  assumptions  are  based  on
management’s  best  knowledge  of  current  events  and  actions  the  Company  may  undertake  in  the  future,
actual results could differ materially from  those estimates.

Our significant accounting policies are described in the ‘‘Notes to Consolidated Financial Statements’’
included in Item 8. Highlighted below are the accounting policies that management considers most critical
to investors’ understanding of our financial results and condition, and that require complex judgments by
management.

Revenue Recognition and Contract Costs

We recognize revenue for most of our contracts using the percentage-of-completion method, primarily
based on contract costs incurred to date compared to total estimated contract costs. We generally utilize
the cost-to-cost approach to estimate the progress towards completion in order to determine the amount of
revenue and profit to recognize. This method of revenue recognition requires us to prepare estimates of
costs  to  complete  contracts  in  progress.  In  making  such  estimates,  judgments  are  required  to  evaluate
contingencies such as potential variances in schedule; the cost of materials and labor productivity; and the
impact  of  change  orders,  liability  claims,  contract  disputes  and  achievement  of  contractual  performance
standards. Changes in total estimated contract cost and losses, if any, could materially impact our results of
operations  or  financial  position.  Certain  of  our  contracts  are  service-related  contracts,  such  as  providing
operations and maintenance services or a variety of technical assistance services. Our service contracts are

66

accounted  for  using  the  proportional  performance  method  under  which  revenue  is  recognized  in
proportion to the number of service activities performed, in proportion to the direct costs of performing
the service activities, or evenly across the period of performance depending upon the nature of the services
provided.

We  recognize  revenue  for  work  performed  under  three  major  types  of  contracts:  fixed-price,

time-and-materials and cost-plus.

Fixed-Price. We  enter  into  two  major  types  of  fixed-price  contracts:  firm  fixed-price  (‘‘FFP’’)  and
fixed-price per unit (‘‘FPPU’’). Under FFP contracts, our clients pay us an agreed fixed-amount negotiated
in  advance  for  a  specified  scope  of  work.  We  generally  recognize  revenue  on  FFP  contracts  using  the
percentage-of-completion  method.  If  the  nature  or  circumstances  of  the  contract  prevent  us  from
preparing  a  reliable  estimate  at  completion,  we  will  delay  profit  recognition  until  adequate  information
about  the  contract’s  progress  becomes  available.  Under  our  FPPU  contracts,  clients  pay  us  a  set  fee  for
each service or production transaction that we complete. Accordingly, we recognize revenue under FPPU
contracts as we complete the related service or production transactions, generally using the proportional
performance method.

Time-and-Materials. Under  time-and-materials  contracts,  we  negotiate  hourly  billing  rates  and
charge our clients based on the actual time that we spend on a project. In addition, clients reimburse us for
our  actual  out-of-pocket  costs  of  materials  and  other  direct  incidental  expenditures  that  we  incur  in
connection with our performance under the contract. The majority of our time-and-material contracts are
subject  to  maximum  contract  values  and,  accordingly,  revenue  under  these  contracts  is  generally
recognized  under  the  percentage-of-completion  method.  However,  time  and  materials  contracts  that  are
service-related  contracts  are  accounted  for  utilizing  the  proportional  performance  method.  Revenue  on
contracts  that  are  not  subject  to  maximum  contract  values  is  recognized  based  on  the  actual  number  of
hours we spend on the projects plus any actual out-of-pocket costs of materials and other direct incidental
expenditures that we incur on the projects. Our time-and-materials contracts also generally include annual
billing rate adjustment provisions.

Cost-Plus. Under  cost-plus  contracts,  we  are  reimbursed  for  allowable  or  otherwise  defined  costs
incurred plus a fee or mark-up. The contracts may also include incentives for various performance criteria,
including  quality,  timeliness,  ingenuity,  safety  and  cost-effectiveness.  In  addition,  our  costs  are  generally
subject to review by our clients and regulatory audit agencies, and such reviews could result in costs being
disputed  as  non-reimbursable  under  the  terms  of  the  contract.  Revenue  for  cost-plus  contracts  is
recognized  at  the  time  services  are  performed  based  upon  the  amounts  we  expect  to  realize  using  the
percentage-of-completion  method.  Revenue  is  not  recognized  for  non-recoverable  costs.  Performance
incentives are included in our estimates  of  revenue  when their realization is reasonably assured.

If estimated total costs on any contract indicate a loss, we recognize the entire estimated loss in the
period the loss becomes known. The cumulative effect of revisions to revenue, estimated costs to complete
contracts,  including  penalties,  incentive  awards,  change  orders,  claims,  anticipated  losses  and  others  are
recorded in the period in which the revisions are identified and the loss can be reasonably estimated. Such
revisions could occur in any reporting period and the effects may be material depending on the size of the
project or the adjustment.

Once  contract  performance  is  underway,  we  may  experience  changes  in  conditions,  client
requirements,  specifications,  designs,  materials  and  expectations  regarding  the  period  of  performance.
Such changes are ‘‘change orders’’ and may be initiated by us or by our clients. In many cases, agreement
with the client as to the terms of change orders is reached prior to work commencing; however, sometimes
circumstances require that work progress without obtaining client agreement. Revenue related to change
orders is recognized as costs are incurred. Change orders that are unapproved as to both price and scope
are evaluated as claims.

67

Claims  are  amounts  in  excess  of  agreed  contract  prices  that  we  seek  to  collect  from  our  clients  or
other third parties for delays, errors in specifications and designs, contract terminations, change orders in
dispute  or  unapproved  as  to  both  scope  and  price  or  other  causes  of  unanticipated  additional  costs.
Revenue  on  claims  is  recognized  only  to  the  extent  that  contract  costs  related  to  the  claims  have  been
incurred and when it is probable that the claim will result in a bona fide addition to contract value that can
be reliably estimated. No profit is recognized on a claim until final settlement occurs. This can lead to a
situation  in  which  costs  are  recognized  in  one  period  and  revenue  is  recognized  in  a  subsequent  period
when a client agreement is obtained  or  a  claim  resolution  occurs.

Insurance Matters, Litigation and Contingencies

In  the  normal  course  of  business,  we  are  subject  to  certain  contractual  guarantees  and  litigation.
Generally, such guarantees relate to project schedules and performance. Most of the litigation involves us
as  a  defendant  in  contractual  disagreements,  workers’  compensation,  personal  injury  and  other  similar
lawsuits. We maintain insurance coverage for various aspects of our business and operations. However, we
have elected to retain a portion of losses that may occur through the use of various deductibles, limits and
retentions under our insurance programs. This practice may subject us to some future liability for which we
are only partially insured or are completely uninsured.

We  record  in  our  consolidated  balance  sheets  amounts  representing  our  estimated  liability  for
self-insurance claims. We utilize actuarial analyses to assist in determining the level of accrued liabilities to
establish for our employee medical and workers’ compensation self-insurance claims that are known and
have been asserted against us, as well as for self-insurance claims that are believed to have been incurred
based  on  actuarial  analyses  but  have  not  yet  been  reported  to  our  claims  administrators  at  the  balance
sheet  date.  We  include  any  adjustments  to  such  insurance  reserves  in  our  consolidated  results  of
operations.

Except  as  described  in  Note  16,  ‘‘Commitments  and  Contingencies,’’  of  the  ‘‘Notes  to  Consolidated
Financial Statements’’ included in Item 8, we do not have any litigation or other contingencies that have
had,  or  are  currently  anticipated  to  have,  a  material  impact  on  our  results  of  operations  or  financial
position.  As  additional  information  about  current  or  future  litigation  or  other  contingencies  becomes
available, management will assess whether such information warrants the recording of additional expenses
relating to those contingencies. Such additional expenses could potentially have a material impact on our
results of operations and financial position.

Stock-Based Compensation

Our  stock-based  compensation  plans  include  stock  options,  restricted  stock  and  an  employee  stock
purchase  plan  for  our  eligible  employees  and  outside  directors.  Stock-based  compensation  cost  is
measured  at  the  grant  date  based  on  the  fair  value  of  the  award  and  is  recognized  as  expense  over  the
requisite  service  period.  Determining  the  fair  value  of  stock-based  awards  at  the  grant  date  requires
management to make assumptions and apply judgment to determine the fair value of our awards. These
assumptions  and  judgments  include  future  employee  turnover  rates,  along  with  estimating  the  future
volatility of our stock price, future stock option exercise behaviors and, for performance-based awards, the
achievement  of  company  performance  goals.  Our  stock-based  compensation  expense  was  $10.8  million,
$10.6 million and $10.2 million for fiscal  2012, 2011  and  2010,  respectively.

Goodwill and Intangibles

The cost of an acquired company is assigned to the tangible and intangible assets purchased and the
liabilities  assumed  on  the  basis  of  their  fair  values  at  the  date  of  acquisition.  The  determination  of  fair
values of assets and liabilities acquired requires us to make estimates and use valuation techniques when a
market value is not readily available. Any excess of purchase price over the fair value of net tangible and

68

intangible  assets  acquired  is  allocated  to  goodwill.  Goodwill  typically  represents  the  value  paid  for  the
assembled workforce and enhancement of our service offerings.

Identifiable intangible assets include backlog, non-compete agreements, client relations, trade names,
patents  and  other  assets.  The  costs  of  these  intangible  assets  are  amortized  over  their  contractual  or
economic lives, which range from one to ten years. We assess the recoverability of the unamortized balance
of our intangible assets when indicators of impairment are present based on expected future profitability
and undiscounted expected cash flows and their contribution to our overall operations. Should the review
indicate that the carrying value is not fully recoverable, the excess of the carrying value over the fair value
of the intangible assets would be recognized as an  impairment loss.

We perform our annual goodwill impairment review at the beginning of our fiscal fourth quarter. Our
annual  review  at  July  2,  2012  (i.e.,  the  first  day  of  our  fiscal  fourth  quarter),  indicated  that  we  had  no
impairment of goodwill, and all of our reporting units had estimated fair values that were in excess of their
carrying  values,  including  goodwill.  In  addition,  we  regularly  evaluate  whether  events  and  circumstances
have  occurred  that  may  indicate  a  potential  change  in  recoverability  of  goodwill.  We  perform  interim
goodwill  impairment  reviews  between  our  annual  reviews  if  certain  events  and  circumstances  have
occurred, including a deterioration in general economic conditions, an increased competitive environment,
a  change  in  management,  key  personnel,  strategy  or  customers,  negative  or  declining  cash  flows,  or  a
decline  in  actual  or  planned  revenue  or  earnings  compared  with  actual  and  projected  results  of  relevant
prior periods.

During the fourth quarter of fiscal 2012, we evaluated whether any of our reorganization activities or
our quarterly re-measurement of our contingent consideration liability resulted in a potential change in the
recoverability of goodwill. During these reviews, we identified one reporting unit in the EAS segment with
impairment,  which  caused  a  non-cash  charge  of  $0.9 million  representing  all  of  the  goodwill  in  this
reporting  unit.  We  also  identified  one  reporting  unit  in  the  TSS  segment  with  goodwill  totaling
$11.4 million  with  a  fair  value  in  excess  of  its  carrying  value  of  less  than  20%.  Although  we  believe  our
assumptions regarding future revenue, costs and operating margins are reasonable for this reporting unit,
they  are  subject  to  uncertainty.  Accordingly,  it  is  reasonably  possible  that  business  performance  for  this
reporting  unit  could  be  below  our  expectations  and  the  goodwill  for  this  operating  unit  could  become
impaired.

We  believe  the  methodology  that  we  use  to  review  impairment  of  goodwill,  which  includes  a
significant  amount  of  judgment  and  estimates,  provides  us  with  a  reasonable  basis  to  determine  whether
impairment has occurred. However, many of the factors employed in determining whether our goodwill is
impaired are outside of our control and it is reasonably likely that assumptions and estimates will change in
future periods. These changes could  result  in future  impairments.

The  goodwill  impairment  review  involves  the  determination  of  the  fair  value  of  our  reporting  units,
which  for  us  are  the  components  one  level  below  our  reportable  segments.  This  process  requires  us  to
make significant judgments and estimates, including assumptions about our strategic plans with regard to
our  operations  as  well  as  the  interpretation  of  current  economic  indicators  and  market  valuations.
Furthermore,  the  development  of  the  present  value  of  future  cash  flow  projections  includes  assumptions
and estimates derived from a review of our expected revenue growth rates, profit margins, business plans,
cost  of  capital  and  tax  rates.  We  also  make  certain  assumptions  about  future  market  conditions,  market
prices,  interest  rates  and  changes  in  business  strategies.  Changes  in  assumptions  or  estimates  could
materially affect the determination of the fair value of a reporting unit. This could eliminate the excess of
fair  value  over  carrying  value  of  a  reporting  unit  entirely  and,  in  some  cases,  result  in  impairment.  Such
changes  in  assumptions  could  be  caused  by  a  loss  of  one  or  more  significant  contracts,  reductions  in
government  or  commercial  client  spending,  or  a  decline  in  the  demand  for  our  services  due  to  changing
economic conditions. In the event that we determine that our goodwill is impaired, we would be required

69

to record a non-cash charge that could result in a material adverse effect on our results of operations or
financial position.

We utilize two methods to determine the fair value of our reporting units: (i) the Income Approach
and (ii) the Market Approach. While  each of these approaches  is initially considered in the  valuation of
the  business  enterprises,  the  nature  and  characteristics  of  the  reporting  units  indicate  which  approach  is
most  applicable.  The  Income  Approach  utilizes  the  discounted  cash  flow  method,  which  focuses  on  the
expected cash flow of the reporting unit. In applying this approach, the cash flow available for distribution
is calculated for a finite period of years. Cash flow available for distribution is defined, for purposes of this
analysis,  as  the  amount  of  cash  that  could  be  distributed  as  a  dividend  without  impairing  the  future
profitability or operations of the reporting unit. The cash flow available for distribution and the terminal
value (the value of the reporting unit at the end of the estimation period) are then discounted to present
value to derive an indication of the value of the business enterprise. The Market Approach is comprised of
the  guideline  company  method  and  the  similar  transactions  method.  The  guideline  company  method
focuses  on  comparing  the  reporting  unit  to  select  reasonably  similar  (or  ‘‘guideline’’)  publicly  traded
companies.  Under  this  method,  valuation  multiples  are  (i)  derived  from  the  operating  data  of  selected
guideline companies; (ii) evaluated and adjusted based on the strengths and weaknesses of the reporting
units relative to the selected guideline companies; and (iii) applied to the operating data of the reporting
unit to arrive at an indication of value. In the similar transactions method, consideration is given to prices
paid in recent transactions that have occurred in the reporting unit’s industry or in related industries. For
our  annual  impairment  analysis  at  July  2,  2012,  we  weighted  the  Income  Approach  and  the  Market
Approach at 70% and 30%, respectively. The Income Approach was given a higher weight because it has
the  most  direct  correlation  to  the  specific  economics  of  the  reporting  unit,  as  compared  to  the  Market
Approach, which is based on multiples  of  broad-based (i.e.,  less comparable) companies.

Contingent  Consideration. Certain  of  our  acquisition  agreements  include  contingent  earn-out
arrangements, which are generally based on the achievement of future operating income thresholds. The
contingent  earn-out  arrangements  are  based  upon  our  valuations  of  the  acquired  companies  and  reduce
the risk of overpaying for acquisitions if the projected financial results are not achieved. For acquisitions
completed  prior  to  fiscal  2010,  contingent  earn-out  payments  are  accrued  as  ‘‘Estimated  earn-out
liabilities’’  when  the  related  operating  income  thresholds  have  been  achieved,  and  a  corresponding
increase in goodwill is recorded. These contingent earn-out payments are reflected as cash flows used in
investing activities on the consolidated  statements of cash flows in the  period paid.

For acquisitions consummated in or after fiscal 2010, the fair values of these earn-out arrangements
are included as part of the purchase price of the acquired companies on their respective acquisition dates.
For  each  transaction,  we  estimate  the  fair  value  of  contingent  earn-out  payments  as  part  of  the  initial
purchase price and record the estimated fair value of contingent consideration as a liability in ‘‘Estimated
contingent  earn-out  liabilities’’  and  ‘‘Other  long-term  liabilities’’  on  the  consolidated  balance  sheets.  We
consider  several  factors  when  determining  that  contingent  earn-out  liabilities  are  part  of  the  purchase
price,  including  the  following:  (1)  the  valuation  of  our  acquisitions  is  not  supported  solely  by  the  initial
consideration  paid,  and  the  contingent  earn-out  formula  is  a  critical  and  material  component  of  the
valuation  approach  to  determining  the  purchase  price;  and  (2)  the  former  shareholders  of  acquired
companies that remain as key employees receive compensation other than contingent earn-out payments
at  a  reasonable  level  compared  with  the  compensation  of  our  other  key  employees.  The  contingent
earn-out payments are not affected by employment termination.

We  measure  our  contingent  earn-out  liabilities  at  fair  value  on  a  recurring  basis  using  significant
unobservable inputs classified within Level 3 of the fair value hierarchy (See Note 2, ‘‘Basis of Presentation
and  Preparation  –  Fair  Value  of  Financial  Instruments’’  of  the  ‘‘Notes  to  Consolidated  Financial
Statements’’ included in Item 8. We use a probability weighted discounted income approach as a valuation
technique  to  convert  future  estimated  cash  flows  to  a  single  present  value  amount.  The  significant
unobservable  inputs  used  in  the  fair  value  measurements  are  operating  income  projections  over  the

70

earn-out period (generally two or three years), and the probability outcome percentages we assign to each
scenario.  Significant  increases  or  decreases  to  either  of  these  inputs  in  isolation  would  result  in  a
significantly  higher  or  lower  liability  with  a  higher  liability  capped  by  the  contractual  maximum  of  the
contingent  earn-out  obligation.  Ultimately,  the  liability  will  be  equivalent  to  the  amount  paid,  and  the
difference between the fair value estimate and amount paid will be recorded in earnings. The amount paid
that  is  less  than  or  equal  to  the  liability  on  the  acquisition  date  is  reflected  as  cash  used  in  financing
activities in our condensed consolidated statements of cash flows. Any amount paid in excess of the liability
on the acquisition date is reflected as  cash used in operating activities.

We review and re-assess the estimated fair value of contingent consideration on a quarterly basis, and
the updated fair value could differ materially from the initial estimates. Changes in the estimated fair value
of  our  contingent  earn-out  liabilities  related  to  the  time  component  of  the  present  value  calculation  are
reported  in  interest  expense.  Adjustments  to  the  estimated  fair  value  related  to  changes  in  all  other
unobservable inputs are reported in operating income.

Income Taxes

We file a consolidated U.S. federal income tax return and combined California franchise tax return. In
addition, we file other returns that are required in the states, foreign jurisdictions and other jurisdictions in
which we do business. We account for certain income and expense items differently for financial reporting
and income tax purposes. Deferred tax assets and liabilities are computed for the differences between the
financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in
the  future  based  on  enacted  tax  laws  and  rates  applicable  to  the  periods  in  which  the  differences  are
expected to reverse. In determining the need for a valuation allowance on deferred tax assets, management
reviews both positive and negative evidence, including current and historical results of operations, future
income projections and potential tax planning strategies. Although realization is not assured, based on our
assessment, we have concluded that it is more likely than not that the deferred tax assets at September 30,
2012, will be realized.

According  to  the  authoritative  guidance  on  accounting  for  uncertainty  in  income  taxes,  we  may
recognize  the  tax  benefit  from  an  uncertain  tax  position  only  if  it  is  more  likely  than  not  that  the  tax
position  will  be  sustained  on  examination  by  the  taxing  authorities  based  on  the  technical  merits  of  the
position. The tax benefits recognized in the financial statements from such a position should be measured
based  on  the  largest  benefit  that  has  a  greater  than  50%  likelihood  of  being  realized  upon  ultimate
settlement. For more information related to our unrecognized tax benefits, see Note 7, ‘‘Income Taxes,’’ of
the ‘‘Notes to Consolidated Financial Statements’’  included in Item 8.

RECENT ACCOUNTING PRONOUNCEMENTS

For  a  discussion  of  recent  accounting  standards  and  the  effect  they  could  have  on  the  consolidated
financial statements, see Note 2, ‘‘Basis of Presentation and Preparation,’’ of the ‘‘Notes to Consolidated
Financial Statements’’ included in Item 8.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We  do  not  enter  into  derivative  financial  instruments  for  trading  or  speculation  purposes.  In  the
normal course of business, we have exposure to both interest rate risk and foreign currency transaction and
translation risk, primarily related to the  Canadian dollar (‘‘CAD’’).

We are exposed to interest rate risk under our Credit Agreement. We may borrow on our Facility, at
our option, at either (a) a base rate (the highest of the U.S. federal funds rate plus 0.50% per annum, the
bank’s prime rate or the Eurocurrency rate plus 1.00%) plus a margin that ranges from 0.50% to 1.50% per
annum, or (b) a Eurocurrency rate plus a margin that ranges from 1.50% to 2.50% per annum. Borrowings
at the base rate have no designated term and may be repaid without penalty any time prior to the Facility’s

71

maturity  date.  Borrowings  at  a  Eurodollar  rate  have  a  term  no  less  than  30  days  and  no  greater  than
90 days. Typically, at the end of such term, such borrowings may be rolled over at our discretion into either
a  borrowing  at  the  base  rate  or  a  borrowing  at  a  Eurodollar  rate  with  similar  terms,  not  to  exceed  the
maturity  date  of  the  Facility.  The  Facility  matures  on  March  28,  2016,  or  earlier  at  our  discretion  upon
payment in full of loans and other obligations. At September 30, 2012, we had $79.2 million in borrowings
outstanding under the Facility at a weighted-average interest rate of 2.15% per annum.

Most  of  our  transactions  are  in  U.S.  dollars;  however,  some  of  our  subsidiaries  conduct  business  in
foreign  currencies,  primarily  the  CAD.  Therefore,  we  are  subject  to  currency  exposure  and  volatility
because of currency fluctuations. We attempt to minimize our exposure to these fluctuations by matching
revenue and expenses in the same currency for our contracts. For fiscal 2012, we had foreign currency gains
of  $0.1  million  compared  to  foreign  currency  losses  of  $1.3  million  in  fiscal  2011.  The  fiscal  2011  losses
were  primarily  attributable  to  intercompany  balances  from  transactions  between  and  advances  made  to
foreign affiliates denominated in currencies other than the U.S. dollar, and the weakening of the values of
certain foreign currencies relative to the U.S. dollar in the fourth quarter of fiscal 2011. These gains and
losses were recognized as part of SG&A  expenses in  our consolidated  statements  of income.

We have foreign currency exchange rate exposure in our results of operations and equity primarily as a
result  of  the  currency  translation  related  to  our  Canadian  subsidiaries  where  the  local  currency  is  the
functional  currency.  To  the  extent  the  U.S.  dollar  strengthens  against  the  CAD,  the  translation  of  these
foreign  currency  denominated  transactions  will  result  in  the  reduced  revenue,  operating  expenses,  assets
and  liabilities.  Similarly,  our  revenue,  operating  expenses,  assets  and  liabilities  will  increase  if  the  U.S.
dollar weakens against the CAD. For fiscal 2012 and 2011, 24.5% and 23.2% of our consolidated revenue,
respectively, was generated by our international business, and such revenue was primarily denominated in
CAD.  For  fiscal  2012,  the  effect  of  foreign  exchange  rate  translation  on  the  consolidated  balance  sheets
was an increase in equity of $26.3 million compared to a reduction in equity of $14.0 million in fiscal 2011.
These amounts were recognized as an adjustment to equity through  other  comprehensive income.

In  fiscal  2009,  we  entered  into  an  intercompany  promissory  note  with  a  wholly-owned  Canadian
subsidiary  in  connection  with  the  acquisition  of  Wardrop  Engineering,  Inc.  The  intercompany  note
receivable is denominated in CAD and has a fixed rate of interest payable in CAD. In the first quarter of
fiscal 2010, we entered into a forward contract for CAD $4.2 million (equivalent to U.S. $4.0 million at the
date of inception) that matured on January 27, 2012. In the second quarter of fiscal 2010, we entered into a
forward  contract  for  CAD  $4.2  million  (equivalent  to  U.S.  $3.9  million  at  the  date  of  inception)  that
matures on January 28, 2013. In the third quarter of fiscal 2011, we entered into a new forward contract for
CAD  $4.2  million  (equivalent  to  U.S.  $4.2  million  at  the  date  of  inception)  that  matures  on  January  27,
2014. In the second quarter of fiscal 2012, we settled one of the foreign currency forward contracts for U.S.
$3.9 million. Our objective is to eliminate variability of our cash flows on the amount of interest income we
receive on the promissory notes from changes in foreign currency exchange rates. For more information,
see  Note  14,  ‘‘Other  Fair  Value  Measurements’’  of  the  ‘‘Notes  to  Consolidated  Financial  Statements’’

REPORT OF INDEPENDENT REGISTERED  PUBLIC  ACCOUNTING FIRM

To the Stockholders of Tetra Tech, Inc.:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements
of  income,  equity  and  cash  flows  present  fairly,  in  all  material  respects,  the  financial  position  of  Tetra
Tech, Inc. and its subsidiaries at September 30, 2012 and October 2, 2011, and the results of their operations
and their cash flows for each of the three years in the period ended September 30, 2012, in conformity with
accounting  principles  generally  accepted  in  the  United  States  of  America.  In  addition,  in  our  opinion,  the
financial  statement  schedule  listed  in  the  accompanying  index  presents  fairly,  in  all  material  respects,  the
information  set  forth  therein  when  read  in  conjunction  with  the  related  consolidated  financial  statements.
Also  in  our  opinion,  the  Company  maintained,  in  all  material  respects,  effective  internal  control  over
financial  reporting  as  of  September  30,  2012  based  on  criteria  established  in  Internal  Control  –  Integrated
Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO).
The  Company’s  management  is  responsible  for  these  financial  statements  and  the  financial  statement
schedule,  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its  assessment  of  the
effectiveness  of  internal  control  over  financial  reporting,  included  in  Management’s  Report  on  Internal
Control  over  Financial  Reporting,  appearing  under  Item  9A  of  this  Form  10-K.  Our  responsibility  is  to
express  opinions  on  these  financial  statements,  on  the  financial  statement  schedule  and  on  the  Company’s
internal  control  over  financial  reporting  based  on  our  integrated  audits.  We  conducted  our  audits  in
accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards  require  that  we  plan  and  perform  the  audits  to  obtain  reasonable  assurance  about  whether  the
financial statements are free of material misstatement and whether effective internal control over financial
reporting was maintained in all material respects. Our audits of the financial statements included examining,
on  a  test  basis,  evidence  supporting  the  amounts  and  disclosures  in  the  financial  statements,  assessing  the
accounting  principles  used  and  significant  estimates  made  by  management,  and  evaluating  the  overall
financial statement presentation. Our audit of internal control over financial reporting included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists,
and testing and evaluating the design and operating effectiveness of internal control based on the assessed
risk.  Our  audits  also  included  performing  such  other  procedures  as  we  considered  necessary  in  the
circumstances. We believe that our audits provide a reasonable basis for our  opinions.

As discussed in Note 2 to the Consolidated Financial Statements, the Company changed the manner

in which it accounts for variable interest  entities  on October 4,  2010.

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 (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. 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business

We  are  a 

leading  provider  of  consulting,  engineering,  program  management,  construction
management, construction and technical services that focuses on addressing fundamental needs for water,
the  environment,  energy,  infrastructure  and  natural  resources.  We  are  a  full-service  company  that  leads
with  science.  We  typically  begin  at  the  earliest  stage  of  a  project  by  identifying  technical  solutions  to
problems and developing execution plans tailored to our clients’ needs and resources. Our solutions may
span the entire life cycle of consulting and engineering projects and include applied science, research and
technology, engineering, design, construction management, construction, operations and maintenance, and
information technology.

2. Basis of Presentation and Preparation

Principles  of  Consolidation  and  Presentation. The  accompanying  consolidated  financial  statements
include  our  accounts  and  those  of  joint  ventures  of  which  we  are  the  primary  beneficiary.  Certain  prior
year amounts for Tetra Tech, Inc. and its reportable segments have been revised to conform to the current
year presentation. These revisions include reclassification of $7.8 million of expenses that were previously
reported in ‘‘Other costs of revenue’’ to be part of ‘‘Selling, general and administrative expenses’’ for fiscal
2011.  In  the  first  quarter  of  fiscal  2012,  we  re-aligned  certain  operating  activities  in  our  reportable
segments to improve organizational effectiveness and efficiency by better aligning operations with similar
client  types,  project  types  and  financial  metrics  (see  Note  17,  ‘‘Reportable  Segments,’’  for  further
discussion). All significant intercompany balances and transactions have been eliminated in consolidation.

Fiscal Year. We report results of operations based on 52 or 53-week periods ending near September 30

of each year. Fiscal years 2012, 2011 and  2010 contained 52,  52 and 53  weeks, respectively.

Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires us to
make  estimates  and  assumptions.  These  estimates  and  assumptions  affect  the  amounts  reported  in  our
consolidated financial statements and accompanying notes. Although such estimates and assumptions are
based  on  management’s  best  knowledge  of  current  events  and  actions  we  may  take  in  the  future,  actual
results could differ materially from those  estimates.

Revenue  Recognition  and  Contract  Costs. We  recognize  revenue  for  most  of  our  contracts  using  the
percentage-of-completion  method,  primarily  based  on  contract  costs  incurred  to  date  compared  to  total
estimated  contract  costs.  We  generally  utilize  the  cost-to-cost  approach  to  estimate  the  progress  towards
completion in order to determine the amount of revenue and profit to recognize. Certain of our contracts
are  service-related  contracts,  such  as  providing  operations  and  maintenance  services  or  a  variety  of
technical assistance services. Our service contracts are accounted for using the proportional performance
method under which revenue is recognized in proportion to the number of service activities performed, in
proportion  to  the  direct  costs  of  performing  the  service  activities,  or  evenly  across  the  period  of
performance depending upon the nature  of the services provided.

We  recognize  revenue  for  work  performed  under  three  major  types  of  contracts:  fixed-price,

time-and-materials and cost-plus.

Fixed-Price. We  enter  into  two  major  types  of  fixed-price  contracts:  FFP  and  FPPU.  Under  FFP
contracts, our clients pay us an agreed fixed-amount negotiated in advance for a specified scope of work.
We  generally  recognize  revenue  on  FFP  contracts  using  the  percentage-of-completion  method.  If  the
nature  or  circumstances  of  the  contract  prevent  us  from  preparing  a  reliable  estimate  at  completion,  we
will  delay  profit  recognition  until  adequate  information  about  the  contract’s  progress  becomes  available.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Basis of Presentation and Preparation (Continued)

Under  our  FPPU  contracts,  clients  pay  us  a  set  fee  for  each  service  or  production  transaction  that  we
complete. Accordingly, we recognize revenue under FPPU contracts as we complete the related service or
production transactions, generally using the  proportional performance method.

Time-and-Materials. Under  time-and-materials  contracts,  we  negotiate  hourly  billing  rates  and
charge our clients based on the actual time that we spend on a project. In addition, clients reimburse us for
our  actual  out-of-pocket  costs  for  materials  and  other  direct  incidental  expenditures  that  we  incur  in
connection with our performance under the contract. The majority of our time-and-material contracts are
subject  to  maximum  contract  values  and,  accordingly,  revenue  under  these  contracts  is  generally
recognized  under  the  percentage-of-completion  method.  However,  time  and  materials  contracts  that  are
service-related  contracts  are  accounted  for  utilizing  the  proportional  performance  method.  Revenue  on
contracts  that  are  not  subject  to  maximum  contract  values  is  recognized  based  on  the  actual  number  of
hours we spend on the projects plus any actual out-of-pocket costs of materials and other direct incidental
expenditures that we incur on the projects. Our time-and-materials contracts also generally include annual
billing rate adjustment provisions.

Cost-Plus. Under  cost-plus  contracts,  we  are  reimbursed  for  allowable  or  otherwise  defined  costs
incurred plus a fee or mark-up. The contracts may also include incentives for various performance criteria,
including  quality,  timeliness,  ingenuity,  safety  and  cost-effectiveness.  In  addition,  our  costs  are  generally
subject to review by our clients and regulatory audit agencies, and such reviews could result in costs being
disputed  as  non-reimbursable  under  the  terms  of  the  contract.  Revenue  for  cost-plus  contracts  is
recognized  at  the  time  services  are  performed  based  upon  the  amounts  we  expect  to  realize  using  the
percentage-of-completion  method.  Revenue  is  not  recognized  for  non-recoverable  costs.  Performance
incentives are included in our estimates  of  revenue  when their realization is reasonably assured.

If estimated total costs on any contract indicate a loss, we recognize the entire estimated loss in the
period the loss becomes known. The cumulative effect of revisions to revenue; estimated costs to complete
contracts,  including  penalties,  incentive  awards,  change  orders,  claims,  liquidated  damages,  anticipated
losses, and other revisions are recorded in the period in which the revisions are identified and the loss can
be  reasonably  estimated.  Such  revisions  could  occur  in  any  reporting  period  and  the  effects  may  be
material depending on the size of the  project  or the adjustment.

Once  contract  performance  is  underway,  we  may  experience  changes  in  conditions,  client
requirements,  specifications,  designs,  materials  and  expectations  regarding  the  period  of  performance.
Such changes are ‘‘change orders’’ and may be initiated by us or by our clients. In many cases, agreement
with the client as to the terms of change orders is reached prior to work commencing; however, sometimes
circumstances require that work progress without obtaining client agreement. Revenue related to change
orders is recognized as costs are incurred. Change orders that are unapproved as to both price and scope
are evaluated as claims.

Claims  are  amounts  in  excess  of  agreed  contract  prices  that  we  seek  to  collect  from  our  clients  or
other third parties for delays, errors in specifications and designs, contract terminations, change orders in
dispute  or  unapproved  as  to  both  scope  and  price,  or  other  causes  of  unanticipated  additional  costs.
Revenue  on  claims  is  recognized  only  to  the  extent  that  contract  costs  related  to  the  claims  have  been
incurred and when it is probable that the claim will result in a bona fide addition to contract value that can
be reliably estimated. No profit is recognized on a claim until final settlement occurs. This can lead to a
situation  in  which  costs  are  recognized  in  one  period  and  revenue  is  recognized  in  a  subsequent  period
when a client agreement is obtained  or  a  claims resolution  occurs.

Cash  and  Cash  Equivalents. Cash  and  cash  equivalents  include  all  highly  liquid  investments  with
maturities  of  90  days  or  less  at  the  date  of  purchase.  Restricted  cash  of  $5.0  million  was  included  in
‘‘Prepaid  expenses  and  other  current  assets’’  on  both  consolidated  balance  sheets  at  fiscal  2012  and
2011 year-ends. For cash held by our  consolidated joint ventures, see Note 15, ‘‘Joint Ventures.’’

Insurance  Matters,  Litigation  and  Contingencies.

In  the  normal  course  of  business,  we  are  subject  to
certain  contractual  guarantees  and  litigation.  In  addition,  we  maintain  insurance  coverage  for  various
aspects  of  our  business  and  operations.  We  record  in  our  consolidated  balance  sheets  amounts
representing our estimated liability for these legal and insurance obligations. We include any adjustments
to these liabilities in our consolidated results  of  operations.

Accounts  Receivable  –  Net. Net  accounts  receivable  is  primarily  comprised  of  billed  and  unbilled
accounts receivable, contract retentions and allowances for doubtful accounts. Billed accounts receivable
represent  amounts  billed  to  clients  that  have  not  been  collected.  Unbilled  accounts  receivable  represent
revenue recognized but not yet billed pursuant to contract terms or billed after the period end date. Most
of our unbilled receivables at September 30, 2012 are expected to be billed and collected within 12 months.
Unbilled  accounts  receivable  also  include  amounts  related  to  requests  for  equitable  adjustment  to
contracts  that  provide  for  price  redetermination  primarily  with  the  U.S.  federal  government.  These
amounts  are  recorded  only  when  they  can  be  reliably  estimated  and  realization  is  probable.  Contract
retentions  represent  amounts  withheld  by  clients  until  certain  conditions  are  met  or  the  project  is
completed,  which  may  be  several  months  or  years.  Allowances  for  doubtful  accounts  represent  the
amounts  that  may  become  uncollectible  or  unrealizable  in  the  future.  We  determine  an  estimated
allowance  for  uncollectible  accounts  based  on  management’s  judgment  regarding  our  operating
performance related to the adequacy of the services performed and delivered, the status of change orders
and  claims,  our  experience  settling  change  orders  and  claims,  and  the  financial  condition  of  our  clients.
Billings in excess of costs on uncompleted contracts represent the amounts of cash collected from clients
and billings to clients on contracts in advance of work performed and revenue recognized. The majority of
these amounts will be earned within 12 months.

Property and Equipment. Property and equipment are recorded at cost and are depreciated over their
estimated  useful  lives  using  the  straight-line  method.  When  property  and  equipment  are  retired  or
otherwise disposed of, the cost and accumulated depreciation are removed from our consolidated balance
sheets and any resulting gain or loss is reflected in our consolidated statements of income. Expenditures
for maintenance and repairs are expensed as incurred. Generally, estimated useful lives range from three
to  ten  years  for  equipment,  furniture  and  fixtures.  Buildings  are  depreciated  over  periods  not  exceeding
40 years. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated
useful lives or the length of the lease.

Long-Lived Assets. Our policy regarding long-lived assets is to evaluate the recoverability of our assets
when the facts and circumstances suggest that the assets may be impaired. This assessment is performed
based on the estimated undiscounted cash flows compared to the carrying value of the assets. If the future
cash  flows  (undiscounted  and  without  interest  charges)  are  less  than  the  carrying  value,  a  write-down
would be recorded to reduce the related asset to its  estimated fair value.

We recognize a liability for contract termination costs associated with an exit activity for costs that will
continue  to  be  incurred  under  a  lease  for  its  remaining  term  without  economic  benefit  to  us,  initially
measured at its fair value at the cease-use date. The fair value is determined based on the remaining lease

rentals, adjusted for the effects of any prepaid or deferred items recognized under the lease, and reduced
by estimated sublease rentals.

Variable  Interest  Entities. At  the  beginning  of  fiscal  2011,  we  adopted  an  accounting  standard  that
requires  us  to  perform  an  analysis  to  determine  whether  our  variable  interests  give  us  a  controlling
financial  interest  in  a  variable  interest  entity  (‘‘VIE’’)  and  whether  we  should  therefore  consolidate  the
VIE. This analysis requires us to assess whether we have the power to direct the activities of the VIE and
the obligation to absorb losses or the right to receive benefits that could potentially be significant to the
VIE. This guidance eliminates the quantitative approach previously required for determining the primary
beneficiary of a VIE and significantly  enhances disclosures.

In the normal course of business, we form joint ventures, including partnerships and partially owned
limited  liability  companies,  with  third  parties  primarily  to  bid  on  and  execute  specific  projects.  In
accordance  with  the  current  consolidation  standard,  we  analyzed  all  of  our  joint  ventures  and  classified
them into two groups: (1) joint ventures that must be consolidated because they are either not VIEs and
we  hold  the  majority  voting  interest,  or  because  they  are  VIEs  and  we  are  the  primary  beneficiary;  and
(2)  joint  ventures  that  do  not  need  to  be  consolidated  because  they  are  either  not  VIEs  and  we  hold  a
minority voting interest, or because they are VIEs and we  are not the primary beneficiary.

Joint ventures are considered VIEs if (1) the total equity investment at risk is not sufficient to permit
the  entity  to  finance  its  activities  without  additional  financial  support;  (2)  as  a  group,  the  holders  of  the
equity investment at risk lack the ability to make certain decisions, the obligation to absorb expected losses
or  the  right  to  receive  expected  residual  returns;  or  (3)  an  equity  investor  has  voting  rights  that  are
disproportionate to its economic interest and substantially all of the entity’s activities are on behalf of the
investor. Many of our joint venture agreements provide for capital calls to fund operations, as necessary;
however, such funding has been historically infrequent and is not anticipated to be material. The majority
of  our  joint  ventures  are  pass-through  entities  for  client  invoicing  purposes.  As  such,  these  are  VIEs
because the total equity investment is typically nominal and not sufficient to permit the entity to finance its
activities without additional financial  support.

We are considered the primary beneficiary and required to consolidate a VIE if we have the power to
direct the activities that most significantly impact that VIE’s economic performance, and the obligation to
absorb losses or the right to receive benefits of that VIE that could potentially be significant to the VIE. In
determining  whether  we  are  the  primary  beneficiary,  our  significant  assumptions  and  judgments  include
the following: (1) identifying the significant activities and the parties that have the power to direct them;
(2) reviewing the governing board composition and participation ratio; (3) determining the equity, profit
and loss ratio; (4) determining the management-sharing ratio; (5) reviewing employment terms, including
which  joint  venture  partner  provides  the  project  manager;  and  (6)  reviewing  the  funding  and  operating
agreements.  Examples  of  significant  activities  include  engineering  and  design  services;  management
consulting  services;  procurement  and  construction  services;  program  management;  construction
management;  and  operations  and  maintenance  services.  If  we  determine  that  the  power  to  direct  the
significant activities is shared by two or more joint venture parties, then there is no primary beneficiary and
no party consolidates the VIE. In making the shared-power determination, we analyze the key contractual
terms, governance, related party and de facto agency as they are defined in the accounting standard, and
other arrangements.

A majority of our joint ventures are unconsolidated VIEs because we are not the primary beneficiary
of  those  joint  ventures.  In  some  cases,  we  consolidate  VIEs  because  we  are  the  primary  beneficiary  of

82

TETRA TECH, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Basis of Presentation and Preparation (Continued)

those joint ventures. In fiscal 2012, there are no changes in the status of the VIEs and no changes to the
primary beneficiary designation of each VIE. Accordingly, we determined that none of the unconsolidated
joint  ventures  should  be  consolidated  and  none  of  the  consolidated  joint  ventures  should  be
de-consolidated.

Business Combinations. The cost of an acquired company is assigned to the tangible and intangible
assets purchased and the liabilities assumed on the basis of their fair values at the date of acquisition. The
determination  of  fair  values  of  assets  and  liabilities  acquired  requires  us  to  make  estimates  and  use
valuation techniques when a market value is not readily available. Any excess of purchase price over the
fair  value  of  net  tangible  and  intangible  assets  acquired  is  allocated  to  goodwill.  Goodwill  typically
represents  the  value  paid  for  the  assembled  workforce  and  enhancement  of  our  service  offerings.
Transaction costs associated with business combinations  are expensed as  they are  incurred.

Goodwill and Intangibles. Goodwill represents the excess of the aggregate purchase price over the fair
value of the net assets acquired in a business acquisition. Following an acquisition, we perform an analysis
to value the acquired company’s tangible and identifiable intangible assets and liabilities. With respect to
identifiable intangible assets, we consider backlog, non-compete agreements, client relations, trade names,
patents and other assets. The costs of these intangible assets are amortized using the straight-line method
over their contractual or economic lives, which range from one to ten years. We assess the recoverability of
the  unamortized  balance  of  our  intangible  assets  when  indicators  of  impairment  are  present  based  on
expected  future  profitability  and  undiscounted  expected  cash  flows  and  their  contribution  to  our  overall
operations.  Should  the  review  indicate  that  the  carrying  value  is  not  fully  recoverable,  the  excess  of  the
carrying  value over the fair value of the intangible  assets would be recognized as  an impairment loss.

We test our goodwill for impairment on an annual basis, and more frequently when an event occurs or
circumstances  indicate  that  the  carrying  value  of  the  asset  may  not  be  recoverable.  We  believe  the
methodology  that  we  use  to  review  impairment  of  goodwill,  which  includes  a  significant  amount  of
judgment  and  estimates,  provides  us  with  a  reasonable  basis  to  determine  whether  impairment  has
occurred.  However,  many  of  the  factors  employed  in  determining  whether  our  goodwill  is  impaired  are
outside  of  our  control  and  it  is  reasonably  likely  that  assumptions  and  estimates  will  change  in  future
periods. These changes could result in future impairments.

We perform our annual goodwill testing on the first day of our fiscal fourth quarter (July 2, 2012, in
fiscal 2012). Our reporting units for goodwill impairment testing are the components one level below our
reportable  segments.  The  annual  impairment  test  for  goodwill  is  a  two-step  process  involving  the
comparison  of  the  estimated  fair  value  of  each  reporting  unit  to  the  reporting  unit’s  carrying  value,
including  goodwill.  If  the  fair  value  of  a  reporting  unit  exceeds  its  carrying  amount,  the  goodwill  of  the
reporting unit is not considered impaired; therefore, the second step of the impairment test is unnecessary.
If the carrying amount of a reporting unit exceeds its fair value, we perform the second step of the goodwill
impairment test to measure the amount of impairment loss to be recorded. If our goodwill were impaired,
we  would  be  required  to  record  a  non-cash  charge  that  could  have  a  material  adverse  effect  on  our
consolidated financial statements.

Contingent  Consideration. Most  of  our  acquisition  agreements 

include  contingent  earn-out
arrangements, which are generally based on the achievement of future operating income thresholds. The
contingent  earn-out  arrangements  are  based  upon  our  valuations  of  the  acquired  companies  and  reduce
the risk of overpaying for acquisitions if the projected financial results are not achieved. For acquisitions

completed  prior  to  fiscal  2010,  contingent  earn-out  payments  are  accrued  as  ‘‘Estimated  earn-out
liabilities’’  when  the  related  operating  income  thresholds  have  been  achieved,  and  a  corresponding
increase in goodwill is recorded. These contingent earn-out payments are reflected as cash flows used in
investing activities on the consolidated  statements of cash flows in the  period paid.

For acquisitions consummated in or after fiscal 2010, the fair values of these earn-out arrangements
are included as part of the purchase price of the acquired companies on their respective acquisition dates.
For  each  transaction,  we  estimate  the  fair  value  of  contingent  earn-out  payments  as  part  of  the  initial
purchase price and record the estimated fair value of contingent consideration as a liability in ‘‘Estimated
contingent  earn-out  liabilities’’  and  ‘‘Other  long-term  liabilities’’  on  the  consolidated  balance  sheets.  We
consider  several  factors  when  determining  that  contingent  earn-out  liabilities  are  part  of  the  purchase
price,  including  the  following:  (1)  the  valuation  of  our  acquisitions  is  not  supported  solely  by  the  initial
consideration  paid,  and  the  contingent  earn-out  formula  is  a  critical  and  material  component  of  the
valuation  approach  to  determining  the  purchase  price;  and  (2)  the  former  shareholders  of  acquired
companies that remain as key employees receive compensation other than contingent earn-out payments
at  a  reasonable  level  compared  with  the  compensation  of  our  other  key  employees.  The  contingent
earn-out payments are not affected by employment termination.

We  measure  our  contingent  earn-out  liabilities  at  fair  value  on  a  recurring  basis  using  significant
unobservable  inputs  classified  within  Level  3  of  the  fair  value  hierarchy.  We  use  a  probability  weighted
discounted  income  approach  as  a  valuation  technique  to  convert  future  estimated  cash  flows  to  a  single
present  value  amount.  The  significant  unobservable  inputs  used  in  the  fair  value  measurements  are
operating income projections over the earn-out period (generally two or three years), and the probability
outcome percentages we assign to each scenario. Significant increases or decreases to either of these inputs
in  isolation  would  result  in  a  significantly  higher  or  lower  liability  with  a  higher  liability  capped  by  the
contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to
the amount paid, and the difference between the fair value estimate and amount paid will be recorded in
earnings. The amount paid that is less than or equal to the liability on the acquisition date is reflected as
cash used in financing activities in our condensed consolidated statements of cash flows. Any amount paid
in excess of the liability on the acquisition date is  reflected  as cash used in operating  activities.

We review and re-assess the estimated fair value of contingent consideration on a quarterly basis, and
the updated fair value could differ materially from the initial estimates. Changes in the estimated fair value
of  our  contingent  earn-out  liabilities  related  to  the  time  component  of  the  present  value  calculation  are
reported  in  interest  expense.  Adjustments  to  the  estimated  fair  value  related  to  changes  in  all  other
unobservable inputs are reported in operating income.

Assets Held for Sale. Assets that meet the held for sale classification criteria are valued at the lower of
their carrying amount or estimated fair value less cost to sell. If the carrying amount of the asset exceeds its
estimated  fair  value  less  cost  to  sell,  an  impairment  loss  is  recognized.  Depreciation,  depletion,  and
amortization expense is not recorded  on assets once they  are classified as  held for  sale.

Fair  Value  of  Financial  Instruments. The  carrying  amounts  of  cash  and  cash  equivalents,  accounts
receivable  and  accounts  payable  approximate  fair  value  because  of  the  short  maturities  of  these
instruments. Any borrowings under our revolving credit facility approximate fair value because the interest
rates  are  based  upon  variable  reference  rates.  Certain  other  assets  and  liabilities,  such  as  contingent
earn-out  liabilities,  assets  held  for  sale  and  forward  foreign  exchange  contracts  that  we  purchased  as
cash-flow hedges, are required to be  carried  in our consolidated financial statements at fair value.

2. Basis of Presentation and Preparation (Continued)

We perform fair value measurements in accordance with the Financial Accounting Standard Board’s
(‘‘FASB’’)  guidance  on  ‘‘Fair  Value  Measurements  and  Disclosures.’’  This  guidance  defines  fair  value  as
the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction
between market participants at the measurement date. When determining the fair value measurements for
assets  and  liabilities  required  to  be  recorded  at  their  fair  values,  we  consider  the  principal  or  most
advantageous market in which we would transact and consider assumptions that market participants would
use  when  pricing  the  assets  or  liabilities,  such  as  inherent  risk,  transfer  restrictions,  and  risk  of
nonperformance.  This  standard  establishes  a  fair  value  hierarchy  that  prioritizes  the  inputs  to  valuation
techniques used to measure fair value  into the following three levels:

Level 1: quoted prices in active markets for identical  assets or liabilities.

Level 2: quoted prices that are observable for the asset or liability, either directly or indirectly such as
quoted prices for similar assets or liabilities in active markets and quoted prices for identical
or similar assets or liabilities in market that are  not active.

Level 3: unobservable inputs based on our own assumptions used to measure assets and liabilities at

fair value.

Stock-Based  Compensation. We  recognize  the  fair  value  of  our  stock-based  compensation  awards  as
compensation expense on a straight-line basis over the requisite service period of the award. We estimate
the fair value of options and stock purchase rights granted using the Black-Scholes option pricing model.
The  fair  value  of  restricted  stock  grants  is  estimated  at  the  grant  date  using  the  market  price  of  the
underlying common stock at the date of grant. The assumptions used in computing the fair value of stock-
based  payments  reflect  our  estimates,  but  involve  uncertainties  relating  to  market  and  other  conditions,
many  of  which  are  outside  of  our  control.  We  estimate  expected  volatility  based  on  historical  daily  price
changes of our stock for a period that approximates the current expected term of the awards, in addition to
recent  option  market  activity.  For  performance-based  awards,  our  expected  performance  is  reviewed  to
determine the percentage of shares pursuant to the award in accordance with our Executive Compensation
Policy. The expected term is the number of years we estimate that the award will be outstanding prior to
exercise considering vesting schedules  and our historical exercise patterns.

Deferred  Compensation. We  maintain  a  non-qualified  defined  contribution  supplemental  retirement
plan for certain key employees that is accounted for in accordance with applicable authoritative guidance
on  accounting  for  deferred  compensation  arrangements  where  amounts  earned  are  held  in  a  rabbi  trust
and  invested.  Employee  deferrals  and  our  match  are  deposited  into  a  rabbi  trust,  and  the  funds  are
generally invested in individual variable life insurance contracts that we own and are specifically designed
to informally fund savings plans of this nature. Our consolidated balance sheets reflect our investment in
variable life insurance contracts in ‘‘Other assets.’’ Our obligation to participating employees is reflected in
‘‘Other  long-term  liabilities.’’  All  income  and  expenses  related  to  the  rabbi  trust  are  reflected  in  our
consolidated statements of income.

Selling, General and Administrative Expenses. SG&A expenses represent overhead expenses that are
not  associated  with  contract  execution  and  are  expensed  in  the  period  incurred.  SG&A  expenses  are
comprised primarily of marketing, bid and proposal costs, and our corporate headquarters’ costs related to
the  executive  offices,  finance,  accounting,  administration  and  information  technology.  Additionally,  we
include in our SG&A expenses the amortization of identifiable intangible assets.

Income  Taxes. We  file  a  consolidated  U.S.  federal  income  tax  return  and  a  combined  California
franchise tax return. In addition, we file other returns that are required in the states, foreign jurisdictions
and  other  jurisdictions  in  which  we  do  business.  We  account  for  certain  income  and  expense  items
differently  for  financial  reporting  and  income  tax  purposes.  Deferred  tax  assets  and  liabilities  are
computed for the difference between the financial statement and tax bases of assets and liabilities that will
result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the
periods  in  which  the  differences  are  expected  to  reverse.  In  determining  the  need  for  a  valuation
allowance,  management  reviews  both  positive  and  negative  evidence,  including  current  and  historical
results of operations, future income projections  and potential  tax planning strategies.

According  to  the  authoritative  guidance  on  accounting  for  uncertainty  in  income  taxes,  we  may
recognize  the  tax  benefit  from  an  uncertain  tax  position  only  if  it  is  more  likely  than  not  that  the  tax
position  will  be  sustained  on  examination  by  the  taxing  authorities  based  on  the  technical  merits  of  the
position. The tax benefits recognized in the financial statements from such a position should be measured
based  on  the  largest  benefit  that  has  a  greater  than  50%  likelihood  of  being  realized  upon  ultimate
settlement.  This  guidance  also  addresses  de-recognition,  classification,  interest  and  penalties  on  income
taxes, accounting in interim periods and  disclosure requirements for uncertain tax positions.

Earnings Per Share. Basic earnings per share (‘‘EPS’’) is computed by dividing net income available to
common  stockholders  by  the  weighted-average  number  of  common  shares  outstanding,  less  unvested
restricted  stock.  Diluted  EPS  is  computed  by  dividing  net  income  by  the  weighted-average  number  of
common shares outstanding and dilutive potential common shares for the period. Potential common shares
include  the  weighted-average  dilutive  effects  of  outstanding  stock  options  and  unvested  restricted  stock
using the treasury  stock method.

Concentration of Credit Risk. Financial instruments that subject us to credit risk consist primarily of
cash and cash equivalents and net accounts receivable. In the event that we have surplus cash, we place our
temporary  cash  investments  with  lower  risk  financial  institutions  and,  by  policy,  limit  the  amount  of
investment exposure to any one financial institution. Approximately 26% and 32% of accounts receivable
were  due  from  various  agencies  of  the  U.S.  federal  government  at  fiscal  2012  and  2011  year-ends,
respectively.  The  remaining  accounts  receivable  are  generally  diversified  due  to  the  large  number  of
organizations  comprising  our  client  base  and  their  geographic  dispersion.  We  perform  ongoing  credit
evaluations of our clients and maintain  an  allowance for potential credit  losses.

Foreign  Currency  Translation. We  determine  the  functional  currency  of  our  foreign  operating  units
based upon the primary currency in which they operate. These operating units maintain their accounting
records in their local currency, primarily Canadian dollars. Where the functional currency is not the U.S.
dollar, translation of assets and liabilities to U.S. dollars is based on exchange rates at the balance sheet
date. Translation of revenue and expenses to U.S. dollars is based on the average rate during the period.
Translation gains or losses are reported as a component of other comprehensive income (loss). Gains or
losses  from  foreign  currency  transactions  are  included  in  results  of  operations,  with  the  exception  of
intercompany  foreign  transactions  that  are  considered  long-term  investments,  which  are  recorded  in
‘‘Accumulated other comprehensive income’’ on the  consolidated balance  sheets.

Recently  Adopted  and  Issued  Accounting  Guidance.

In  January  2010,  the  FASB  issued  updated
accounting  guidance  that  amends  the  disclosure  requirements  with  respect  to  fair  value  measurements.
Specifically, the new guidance requires disclosure of amounts transferred in and out of Levels 1 and 2 fair

86

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Basis of Presentation and Preparation (Continued)

value  measurements,  a  reconciliation  presented  on  a  gross  basis  rather  than  a  net  basis  of  activity  in
Level  3  fair  value  measurements,  greater  disaggregation  of  the  assets  and  liabilities  for  which  fair  value
measurements  are  presented,  and  more  robust  disclosure  of  the  valuation  techniques  and  inputs  used  to
measure  Level  2  and  3  fair  value  measurements.  Part  of  this  guidance  was  effective  for  us  in  the  first
quarter  of  fiscal  2011.  We  adopted  the  additional  requirement  on  Level  3  fair  value  measurements  on
October  3,  2011.  The  adoption  of  this  guidance  did  not  have  a  material  impact  on  the  consolidated
financial statements.

In December 2010, the FASB issued updated accounting guidance to clarify that pro forma disclosures
should be presented as if a business combination occurred at the beginning of the prior annual period for
purposes of preparing both the current reporting period and the prior reporting period pro forma financial
information.  These  disclosures  should  be  accompanied  by  a  narrative  description  about  the  nature  and
amount  of  material,  nonrecurring  pro  forma  adjustments.  The  new  accounting  guidance  is  effective
prospectively for business combinations for which the acquisition date is on or after the beginning of the
first  annual  reporting  period  beginning  on  or  after  December  15,  2010.  We  adopted  this  guidance  on
October  3,  2011;  however,  no  business  combinations  completed  in  fiscal  2012  were  considered  material,
individually or in aggregate, to our consolidated financial statements.

In  December  2010,  the  FASB  issued  updated  accounting  guidance  to  amend  the  criteria  for
performing  Step  2  of  the  goodwill  impairment  test  for  reporting  units  with  zero  or  negative  carrying
amounts and requires performing Step 2 if qualitative factors indicate that it is more likely than not that a
goodwill impairment exists. We adopted the disclosures on October 3, 2011, and it did not have an impact
on our consolidated financial statements.

In May 2011, the FASB issued updated guidance to improve comparability of fair value measurements
between  U.S.  GAAP  and  International  Financial  Reporting  Standards.  This  update  amends  current  fair
value measurement and disclosure guidance to include increased transparency around valuation inputs and
investment categorization. The updated guidance is effective for fiscal years and interim periods beginning
after December 15, 2011. We adopted the updated guidance in the second quarter of fiscal 2012 and it did
not have an impact on our consolidated financial statements.

In June 2011, the FASB issued new guidance on the presentation of comprehensive income. The new
guidance allows an entity to present components of net income and other comprehensive income in either
a single continuous statement of comprehensive income or in two separate but consecutive statements. The
new guidance eliminates the current option to report other comprehensive income and its components in
the  statement  of  changes  in  equity.  While  the  new  guidance  changes  the  presentation  of  comprehensive
income, there are no changes to the components that are recognized in net income or other comprehensive
income  under  current  accounting  guidance.  Additionally,  in  December  2011,  the  FASB  issued  new
guidance to defer the effective date pertaining to present reclassification adjustments out of accumulated
other  comprehensive  income  by  component  in  both  the  statement  in  which  net  income  is  presented  and
the statement in which other comprehensive income is presented. During the deferral period, the existing
requirements in the original guidance for the presentation of reclassification adjustments must continue to
be followed. This new guidance is effective for the first quarter  of  fiscal 2013 on  a retrospective  basis.

In  September  2011,  the  FASB  issued  updated  accounting  guidance  to  simplify  how  an  entity  tests
goodwill for impairment. The amendment permits an entity to first assess qualitative factors to determine
whether it is necessary to perform the two-step quantitative goodwill impairment test. An entity will not be
required  to  calculate  the  fair  value  of  a  reporting  unit  unless  the  entity  determines  that  it  is  more  likely

than not that its fair value is less than its carrying amount. The updated guidance is effective in fiscal year
2013. Early adoption is permitted; however, we have not yet adopted it. We do not expect the adoption of
this  guidance to have a material impact  on our consolidated financial statements.

In December 2011, the FASB issued new guidance to enhance disclosures about financial instruments
and  derivative  instruments  that  are  either  offset  on  the  statement  of  financial  position  or  subject  to  an
enforceable  master  netting  arrangement  or  similar  agreement,  irrespective  of  whether  they  are  offset  on
the  statement  of  financial  position.  Entities  are  required  to  provide  both  net  and  gross  information  for
these assets and liabilities in order to facilitate comparability between financial statements prepared on the
basis of U.S. GAAP and financial statements prepared on the basis of International Financial Reporting
Standards.  This  updated  guidance  will  be  effective  for  the  first  quarter  of  fiscal  2014  on  a  retrospective
basis and we are evaluating the impact on  our consolidated financial statements.

Billed accounts receivable represent amounts billed to clients that have not been collected. Unbilled
accounts  receivable  represent  revenue  recognized  but  not  yet  billed  pursuant  to  contract  terms  or  billed
after the period end date. Most of our unbilled receivables at September 30, 2012 are expected to be billed
and collected within 12 months. Unbilled accounts receivable at September 30, 2012 and October 2, 2011,
include  approximately  $21  million  and  $16  million,  respectively,  related  to  claims,  and  requests  for
equitable  adjustment  on  contracts  that  provide  for  price  redetermination  primarily  with  U.S.  federal
government  agencies.  These  amounts  are  management’s  estimate  of  the  most  probable  amount  to  be
realized upon the conclusion of the claims settlement process. We regularly evaluate these claim amounts
and record appropriate adjustments to operating earnings when collection is deemed to have changed. No
material losses were recognized related to the collectability of claims during fiscal 2012 and 2011. Contract
retentions  represent  amounts  withheld  by  clients  until  certain  conditions  are  met  or  the  project  is

completed,  which  may  be  several  months  or  years.  The  allowance  for  doubtful  accounts  is  determined
based  on  a  review  of  client-specific  accounts,  and  contract  issues  resulting  from  current  events  and
economic circumstances. Billings in excess of costs on uncompleted contracts represent the amount of cash
collected from clients and billings to clients on contracts in advance of revenue recognized. The majority of
billings  in  excess  of  costs  on  uncompleted  contracts  will  be  earned  within  12  months.  The  non-current
billings  in  excess  of  costs  on  uncompleted  contracts  were  reported  as  part  of  our  ‘‘Other  long-term
liabilities’’ on our consolidated balance sheets.

Billed  accounts  receivable  related  to  U.S.  federal  government  contracts  were  $65.9  million  and
$88.5 million at September 30, 2012 and October 2, 2011, respectively. U.S. federal government unbilled
receivables, net of progress payments, were $100.4 million and $102.7 million at September 30, 2012 and
October 2, 2011, respectively. Other than the U.S. federal government, no single client accounted for more
than 10% of our accounts receivable  at  September 30, 2012  and October  2, 2011.

4. Mergers and Acquisitions

In  fiscal  2010,  we  made  certain  acquisitions  that  enhanced  our  service  offerings  and  expanded  our
geographic  presence  in  the  ECS,  TSS  and  RCM  segments.  The  aggregate  purchase  price  for  fiscal  2010
acquisitions was $107.3 million as of the respective acquisition dates, of which $86.6 million was paid to the
sellers and $20.7 million was the estimated fair value of contingent earn-out liabilities on acquisition with
an aggregate maximum of $26.7 million  upon the achievement  of  specified financial objectives.

At the beginning of the first quarter of fiscal 2011, we acquired all of the outstanding capital stock of
BPR,  Inc.  (‘‘BPR’’),  a  Canadian  scientific  and  engineering  services  firm  that  provides  multidisciplinary
consulting  and  engineering  support  for  water,  energy,  industrial  plants,  buildings  and  infrastructure
projects. This acquisition further expanded our geographic presence in eastern Canada, and enabled us to
provide  clients  with  additional  services  throughout  Canada.  BPR  is  part  of  our  ECS  segment.  The
estimated fair value of the purchase price was $185.7 million as of the acquisition date, of which payments
of $157.0 million were financed with borrowings under our credit facility and available cash resources and
$28.7 million was the estimated fair value of contingent earn-out liabilities on acquisition with a maximum
of  $39.2  million  upon  the  achievement  of  specified  financial  objectives  over  a  two-year  period  from  the
acquisition date. The goodwill related to the BPR acquisition represented the value paid for the assembled
work  force,  the  international  geographic  presence  in  eastern  Canada,  and  engineering  and  consulting

In fiscal 2011, we made other acquisitions that further enhanced our service offerings and expanded
our  geographic  presence  in  the  ECS  and  TSS  segments.  The  aggregate  purchase  price  for  these
acquisitions  was  $100.3  million  as  of  the  respective  acquisition  dates.  Of  this  amount,  $68.7  million  was
paid to the sellers, $4.5 million was accrued in accordance to the purchase agreements and $26.9 million
was  the  estimated  fair  value  of  contingent  earn-out  obligations  with  an  aggregate  maximum  of
$32.3 million upon the achievement of  specified  financial objectives.

In fiscal 2012, we made acquisitions that enhanced our service offerings and expanded our geographic
presence  in  our  ECS  and  TSS  segments.  The  aggregate  purchase  price  for  these  acquisitions  was
$63.2 million as of the respective acquisition dates. Of this amount, $42.2 million was paid to the sellers,
$2.0  million  was  accrued  in  accordance  to  the  purchase  agreements  and  $19.0  million  was  the  estimated
fair  value  of  contingent  earn-out  obligations  with  an  aggregate  maximum  of  $20.0  million  upon  the
achievement of specified financial objectives.

Goodwill  additions  resulting  from  the  above  business  combinations  are  primarily  attributable  to  the
existing  workforce  of  the  acquired  companies  and  synergies  expected  to  arise  after  the  acquisitions.  The
results of these acquisitions were included on the consolidated financial statements from their respective
closing dates. None of the acquisitions were considered material, individually or in the aggregate, for the
respective reporting periods. As a result, no pro forma information has been provided. The purchase price
allocations  related  to  fiscal  2012  acquisitions  are  preliminary,  and  subject  to  adjustment,  based  on  the
valuation and final determination of net assets acquired. We do not believe that any adjustments will have
a material effect on the consolidated results of operations.

The aggregate current estimated earn-out liabilities of $35.4 million and $64.1 million are reported in
‘‘Estimated contingent earn-out liabilities,’’ and the aggregate non-current estimated earn-out liabilities of
$16.1 million and $11.0 million are reported in ‘‘Other long-term liabilities’’ on the consolidated balance
sheets at September 30, 2012 and October 2, 2011, respectively. Each contingent consideration is based on
future  operating  income,  and  its  fair  value  is  estimated  by  management  assessing  the  probability  of  the
results  being  achieved  in  the  future.  At  September  30,  2012,  there  was  a  maximum  of  $3.0  million  of
contingent consideration remaining for acquisitions completed prior to fiscal 2010 that will be recorded as
an  addition  to  goodwill  if  earned.  At  September  30,  2012,  there  was  a  maximum  of  $68.4  million  of
contingent consideration remaining for  acquisitions  completed in or after fiscal 2010.

4. Mergers and Acquisitions (Continued)

Every quarter-end, we re-measure the fair value of our contingent earn-out liabilities by re-evaluating
the significant unobservable inputs and probability weightings in our discounted income valuation models.
Any  resulting  decreases  or  increases  in  the  fair  value  result  in  a  corresponding  gain  or  loss  reported  in
operating  income.  During  fiscal  2012,  2011  and  2010,  we  recorded  a  net  decrease  in  our  contingent
earn-out liabilities and reported related net gains in operating income of $19.2 million ($17.3 million in the
fourth quarter), $1.8 million and $0.3 million, respectively, as a result of re-measurements of fair value. In
each case, subsequent to the acquisition date, we determined that the related acquired companies would
achieve operating income different than the estimated level used to calculate the fair value. On a net basis,
the updated estimates of operating income were lower than the original projections. The $17.3 million net
decrease  in  our  contingent  earn-out  liabilities  in  the  fourth  quarter  of  fiscal  2012  included  $12.5 million
related  to  our  determination  in  that  quarter  that  one  of  our  acquisitions  in  the  TSS  segment  would  not
achieve  the  operating  income  we  previously  expected  for  the  earn-out  period.  The  remaining  fourth
quarter net earn-out adjustments primarily related to several of our recent acquisitions in the ECS segment
for which the earn-out periods concluded in the fourth quarter of fiscal 2012. Although certain acquired
operating units with contingent earn-outs are currently expected to or did achieve lower operating income
than we estimated at the time of acquisition, their results, projected earnings and related cash flows did not
result in goodwill impairment.

Goodwill additions are attributable to acquisitions described in Note 4, ‘‘Mergers and Acquisitions,’’
for the respective fiscal years. Substantially all of the goodwill additions are not deductible for income tax
purposes.  Currency  translation  adjustments  related  to  our  foreign  subsidiaries  with  functional  currencies
that  are  different  than  our  reporting  currency.  Goodwill  adjustments  resulted  primarily  from  earn-out
payments and accruals associated with acquisitions consummated prior to fiscal 2010, which are accounted
for  as  goodwill  adjustments  under  previous  accounting  rules.  Inter-segment  transfers  related  to  the
realignment of certain operating activities in our reportable segments in the first quarter of fiscal 2012. For
more information regarding the fiscal 2012 realignment, see Note 17, ‘‘Reportable Segments.’’ A goodwill
impairment charge of $0.9 million was recognized in the fourth quarter of fiscal 2012 for a reporting unit in
the  EAS  segment.  This  reporting  unit  reported  lower  than  planned  operating  income  during  the  fourth
quarter  of  fiscal  2012,  and  projected  future  operating  losses  and  negative  cash  flows.  The  impairment
represented all of the goodwill for this reporting unit.

Gross  amount  of  goodwill  for  the  EAS  segment  was  $122.7  million  for  both  fiscal  2012  and
2011 year-ends. We recorded impairment charges of $105.0 million in fiscal 2005 and $0.9 million in fiscal
2012. Accordingly, accumulated impairment losses for this segment were $105.9 million and $105.0 million
for September 30, 2012 and October 2, 2011, respectively. There were no impairment charges in the other
reportable segments.

Amortization  expense  for  these  intangible  assets  for  fiscal  2012,  2011  and  2010  was  $29.6  million,

was $26.7 million, $27.1 million and $20.4 million  for  fiscal 2012, 2011 and 2010, respectively.

During  the  fourth  quarter  of  fiscal  2012,  one  of  our  properties  met  the  held  for  sale  classification
criteria  at  fiscal  2012  year-end.  This  property  consists  of  land  and  a  building  at  a  net  book  value  of
$5.8 million. We estimated the fair value of this property using market values for similar properties, and
this is considered a Level 3 measurement as defined in FASB’s guidance on ‘‘Fair Value Measurements and
Disclosures.’’  After  adjustment  to  fair  value,  the  $2.4  million  carrying  value  of  this  property  has  been
reclassified  to  ‘‘Prepaid  expenses  and  other  current  assets’’  in  the  consolidated  balance  sheet  at
September 30, 2012. Additionally, we recorded the related non-cash impairment charge of $3.4 million in
our corporate ‘‘Selling, general and administrative expenses’’ in the consolidated statement of income for

Our  fiscal  year  2012  effective  tax  rate  was  34.9%  compared  to  33.8%  for  fiscal  2011.  The  higher
effective tax rate resulted primarily from the non-extension of R&E credits subsequent to December 31,
2011. The R&E credits expired on December 31, 2011 for federal purposes but California R&E credits are
still available. We are currently under examination by the IRS for the fiscal years 2005 through 2009, and
by  the  California  Franchise  Tax  Board  for  fiscal  years  2004  through  2005,  with  respect  to  R&E  credits.

We have performed an assessment of positive and negative evidence regarding the realization of the
deferred tax assets at September 30, 2012. This assessment included the evaluation of scheduled reversals
of  deferred  tax  liabilities,  availability  of  carry-backs,  and  estimates  of  projected  future  taxable  income.
Although realization is not assured, based on our assessment, we have concluded that it is more likely than
not that the assets will be realized except for the assets related to loss carry-forwards in India for which a
valuation allowance of $2.5 million has  been provided.

At  September  30,  2012,  undistributed  earnings  of  our  foreign  subsidiaries,  primarily  in  Canada,
amounting  to  approximately  $37.0  million  are  expected  to  be  permanently  reinvested.  Accordingly,  no
provision  for  U.S.  income  taxes  or  foreign  withholding  taxes  has  been  made.  Upon  distribution  of  those
earnings,  we  would  be  subject  to  U.S.  income  taxes  and  foreign  withholding  taxes.  Determination  of  the
amount  of  unrecognized  deferred  U.S.  income  tax  liability  is  not  practicable;  however,  the  potential
foreign tax credit associated with the deferred income would be available to partially reduce the resulting
U.S. tax liabilities.

recognized, would affect our effective tax rate. It is not expected that there will be a significant change in

Our  Credit  Agreement  provides  for  a  $460  million  five-year  Facility,  which  includes  a  $200  million
sublimit  for  the  issuance  of  standby  letters  of  credit  and  a  $100  million  sublimit  for  multicurrency
borrowings  and  letters  of  credit.  At  our  election,  the  Facility  may  be  increased  from  time  to  time  by  an
amount up to $140 million in the aggregate, provided that no existing lender is required to commit to any
such  increased  amount.  Borrowings  under  the  Credit  Agreement  are  collateralized  by  our  accounts
receivable,  the  stock  of  our  subsidiaries  and  intercompany  loans.  At  September  30,  2012,  we  had
$79.2  million  in  borrowings  outstanding  at  a  weighted-average  interest  rate  of  2.15%  per  annum,
$19.0  million  in  standby  letters  of  credit  and  $361.8  million  in  availability  under  the  Facility.  We  had

97

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

8. Long-Term Debt (Continued)

$14.2 million in multicurrency borrowings and standby letters of credit under the Facility at September 30,
2012.

Interest  on  borrowings  under  the  Credit  Agreement  is  payable,  at  our  election,  at  either  (a)  a  base
rate  (the  highest  of  the  U.S.  federal  funds  rate  plus  0.50%  per  annum,  the  bank’s  prime  rate  or  the
Eurocurrency  rate  plus  1.00%)  plus  a  margin  that  ranges  from  0.50%  to  1.50%  per  annum,  or  (b)  a
Eurocurrency rate plus a margin that ranges from 1.50% to 2.50% per annum. Borrowings at the base rate
have no designated term and may be repaid without penalty any time prior to the Facility’s maturity date.
Borrowings at a Eurodollar rate have a term no less than 30 days and no greater than 90 days. Typically, at
the end of such term, such borrowings may be rolled over at our discretion into either a borrowing at the
base  rate  or  a  borrowing  at  a  Eurodollar  rate  with  similar  terms,  not  to  exceed  the  maturity  date  of  the
Facility. The Facility matures on March 28, 2016, or earlier at our discretion upon payment in full of loans
and other obligations.

In  fiscal  2012,  other  debt  includes  capital  leases  of  $2.8  million,  property  and  equipment  loans  of
$0.5  million,  and  a  bank  overdraft  facility  of  $0.5  million  at  one  of  our  foreign  affiliates.  In  fiscal  2011,
other debt includes capital leases of $1.7 million, property and equipment loans of $1.2 million, and a bank
overdraft facility of $0.7 million at one  of our foreign affiliates.

We entered into two letters of credit agreements with two banks to issue up to $30 million in standby
letters of credit. In fiscal 2012, we entered into a third letter of credit agreement with a third bank to issue
up  to  $10  million  in  standby  letters  of  credit.  The  amount  of  standby  letters  of  credit  outstanding  under
these facilities at September 30, 2012 was  $5.3 million, issued in currencies other  than the U.S. dollar.

We vacated certain facilities under long-term non-cancelable leases and recorded contract termination
costs of $1.3 million at corporate in fiscal 2012 and $1.3 million at the RCM segment in fiscal 2011. This
amount  was  initially  measured  at  the  fair  value  of  the  portion  of  the  lease  payments  associated  with  the
vacated facilities, reduced by estimated sublease rentals, less the write off of a prorated portion of existing
deferred items previously recognized on these leases. We expect the remaining lease payments to be paid
through the various lease expiration dates that continue until 2017. The RCM contract termination costs

10. Stockholders’ Equity and Stock Compensation Plans

At September 30, 2012, we had the following  stock-based compensation  plans:

(cid:129) 2003  Outside  Director  Stock  Option  Plan. Non-employee  directors  may  be  granted  options  to
purchase an aggregate of up to 400,000 shares of our common stock at prices not less than 100% of
the  market  value  on  the  date  of  grant.  Exercise  prices  of  all  options  granted  were  at  the  market
value on the date of grant. These options vest and become exercisable on the first anniversary of the
date of grant if the director has not ceased to be a director prior to such date, and expire no later
than ten years from the grant date.

(cid:129) 2005  Equity  Incentive  Plan. Key  employees  and  non-employee  directors  may  be  granted  equity
awards, including stock options, restricted stock and restricted stock units (‘‘RSUs’’), with respect to
an aggregate of 6,086,216 shares of our common stock. Options granted before March 6, 2006 vest
at 25% on the first anniversary of the grant date, and the balance vests monthly thereafter, such that
these  options  become  fully  vested  no  later  than  four  years  from  the  date  of  grant.  These  options
expire no later than ten years from the date of grant. Options granted on and after March 6, 2006
vest at 25% on each anniversary of  the grant  date. These options expire no later  than eight years
from the grant date. RSUs granted to date vest at 25% on  each anniversary of the grant  date.

10. Stockholders’ Equity and Stock Compensation  Plans (Continued)

In accordance with our Executive Compensation Policy, our Compensation Committee has awarded
restricted  stock  to  executive  officers  and  non-employee  directors  under  the  2005  Equity  Incentive
Plan.  Restricted  stock  grants  generally  vest  over  a  minimum  three-year  period,  and  may  be
performance-based, determined by EPS growth, or service-based.

(cid:129) Employee Stock Purchase Plan (‘‘ESPP’’). Purchase rights to purchase common stock are granted to
our eligible full and part-time employees, and shares of common stock are issued upon exercise of
the purchase rights. An aggregate of 2,373,290 shares may be issued pursuant to such exercise. The
maximum  amount  that  an  employee  can  contribute  during  a  purchase  right  period  is  $5,000.  The
exercise  price  of  a  purchase  right  is  the  lesser  of  100%  of  the  fair  market  value  of  a  share  of
common stock on the first day of the purchase right period or 85% of the fair market value on the
last day of the purchase right period  (calendar year).

The  aggregate  intrinsic  value  in  the  table  above  represents  the  total  intrinsic  value  (the  difference
between  our  closing  stock  price  on  the  last  trading  day  of  fiscal  2012  and  the  exercise  price,  times  the
number of shares) that would have been received by the in-the-money option holders if they had exercised
their options on September 30, 2012. This amount will change based on the fair market value of our stock.
At September 30, 2012, we expect to recognize $10.3 million of unrecognized compensation cost related to
stock  option  grants  over  a  weighted-average  period  of  1.9  years.  At  September  30,  2012,  there  were
approximately 2.6 million options available  for future awards.

The weighted-average fair value of stock options granted during fiscal 2012, 2011 and 2010 was $8.37,
$9.08 and $10.09, respectively. The aggregate intrinsic value of options exercised during fiscal 2012, 2011
and 2010 was $6.1 million, $2.3 million and $2.2  million, respectively.

The fair value of our stock options was estimated on the date of grant using the Black-Scholes option

pricing model. The following assumptions  were used in  the calculation:

4.8 - 5.5

–
42.6 -  43.4%
2.0%  - 2.5%
4.4  - 5.6

For purposes of the Black-Scholes model, forfeitures were estimated based on historical experience.
For  the  fiscal  2012,  2011  and  2010  year-ends,  we  based  our  expected  stock  price  volatility  on  historical
volatility  behavior  and  current  implied  volatility  behavior.  Our  risk-free  rate  of  return  was  based  on
constant  maturity  rates  provided  by  the  U.S.  Treasury.  The  expected  life  was  based  on  historical
experience.

Net cash proceeds from the exercise of stock options were $18.2 million, $8.4 million and $3.4 million
for fiscal 2012, 2011 and 2010, respectively. Our policy is to issue shares from our authorized shares upon
the exercise of stock options. The actual income tax benefit realized from exercises of nonqualified stock
options and disqualifying dispositions of qualified options for fiscal 2012, 2011 and 2010 was $3.2 million,
$1.4 million and $2.0 million, respectively.

Restricted Stock and RSUs

In  fiscal  2012,  2011  and  2010,  we  awarded  105,567  shares,  94,606  shares  and  88,258  shares,
respectively, of restricted stock to certain of our executive officers and non-employee directors. Of these
288,431 awards, 10,000 shares were time-based, and are dependent on the officer’s continued employment
with  us,  but  otherwise  vest  over  a  three-year  period.  The  remaining  278,431  shares  were  performance-
based,  such  that  the  percentage  of  awarded  shares  that  ultimately  vests,  from  0%  to  140%,  depends  on
fiscal year earnings per share growth rates for the three fiscal years that end after the award date. In fiscal
2012,  2011  and  2010,  an  additional  5,305  shares,  8,356  shares  and  11,557  shares  of  restricted  stock,
respectively, were awarded for performance-based adjustments in excess of 100% vesting. Restricted stock
forfeitures result from employment terminations prior to vesting, and from performance-based vesting of

101

less  than  100%.  Forfeited  shares  return  to  the  pool  of  authorized  shares  available  for  award.  As  of
September 30, 2012, there were 1,251,518 shares available for future  awards of restricted  stock.

The  fair  value  of  the  total  compensation  cost  of  each  restricted  stock  award  was  determined  at  the
date  of  grant  using  the  market  price  of  the  underlying  common  stock  as  of  the  date  of  grant.  For
performance-based  awards,  our  expected  performance  is  reviewed  to  estimate  the  percentage  of  shares
that  will  vest.  The  total  compensation  cost  of  the  awards  is  then  amortized  over  their  applicable  vesting
period on a straight-line basis.

In the first quarter of fiscal 2012, we also awarded 181,348 RSUs to our employees at the fair value of
$22.53 per share on the award date. All of the RSUs have time-based vesting over a four-year period. At
September  30,  2012,  there  were  171,967  shares  of  RSUs  outstanding.  Restricted  stock  unit  forfeitures
result  from  employment  terminations  prior  to  vesting.  Forfeited  shares  return  to  the  pool  of  authorized
shares available for award.

The  stock-based  compensation  expense  related  to  restricted  stock  and  RSUs  for  fiscal  years  2012,
2011 and 2010 was $2.2 million, $1.7 million and $1.2 million, respectively, and was included in the total
stock-based  compensation  expense.  At  September  30,  2012,  there  was  $2.5  million  of  unrecognized
compensation  costs  related  to  the  restricted  stock  and  RSUs  that  will  be  substantially  recognized  by  the
end of fiscal 2015.

For  fiscal  2012,  2011  and  2010,  we  based  our  expected  stock  price  volatility  on  historical  volatility
behavior  and  current  implied  volatility  behavior.  The  risk-free  rate  of  return  was  based  on  constant
maturity  rates  provided  by  the  U.S.  Treasury.  The  expected  life  was  based  on  the  ESPP  terms  and
conditions.

Included  in  stock-based  compensation  expense  for  fiscal  2012,  2011  and  2010  was  a  charge  of
$0.9 million, $1.0 million and $1.3 million, respectively, related to the ESPP. The unrecognized stock-based

103

10. Stockholders’ Equity and Stock Compensation  Plans (Continued)

compensation costs for awards granted under the ESPP at September 30, 2012, and October 2, 2011, were
$0.2  million  and  $0.3  million,  respectively.  At  September  30,  2012,  ESPP  participants  had  accumulated
$2.8 million to purchase our common stock.

11. Retirement Plans

We  have  established  defined  contribution  plans  including  401(k)  plans.  Generally,  employees  are
eligible to participate in the defined contribution plans upon completion of one year of service and in the
401(k) plans upon commencement of employment. For fiscal 2012, 2011 and 2010, employer contributions
to the plans were $14.7 million, $14.1  million and $13.8 million, respectively.

We  have  established  a  non-qualified  deferred  compensation  plan  for  certain  key  employees  and
non-employee  directors.  Eligible  employees  and  non-employee  directors  may  elect  to  defer  receipt  of
salary,  incentive  payments  and  Board  of  Directors’  fees,  which  are  generally  invested  by  us  in  individual
variable life insurance contracts we own that are designed to informally fund savings plans of this nature.
At September 30, 2012, and October 2, 2011, the consolidated balance sheets reflect assets of $13.4 million
and $11.3 million, respectively, related to the deferred compensation plan in ‘‘Other assets,’’ and liabilities
of  $12.9  million  and  $10.6  million,  respectively,  related  to  the  deferred  compensation  plan  in  ‘‘Other
long-term liabilities.’’

104

computation  of  dilutive  potential  common  shares  because  the  assumed  proceeds  per  share  exceeded  the
average  market  price  per  share  for  that  period.  Therefore,  their  inclusion  would  have  been  anti-dilutive.

13. Comprehensive Income

Comprehensive  income  is  comprised  of  net  income,  translation  gains  and  losses  from  foreign
subsidiaries  with  functional  currencies  different  than  our  reporting  currency,  and  unrealized  gains  and
losses on hedging activities. The components of comprehensive income, net of related tax, are as follows:

Derivative  Instruments.

In  fiscal  2009,  we  entered  into  an  intercompany  promissory  note  with  a
wholly-owned  Canadian  subsidiary  in  connection  with  the  acquisition  of  Wardrop  Engineering,  Inc.  The
intercompany note receivable is denominated in Canadian dollars (‘‘CAD’’) and has a fixed rate of interest
payable  in  CAD.  In  the  first  quarter  of  fiscal  2010,  we  entered  into  a  forward  contract  for  CAD
$4.2 million (equivalent to U.S. $4.0 million at the date of inception) that matured on January 27, 2012. In
the second quarter of fiscal 2010, we entered into a forward contract for CAD $4.2 million (equivalent to
U.S. $3.9 million at the date of inception) that matures on January 28, 2013. In the third quarter of fiscal
2011, we entered into a forward contract for CAD $4.2 million (equivalent to U.S. $4.2 million at the date
of inception) that matures on January 27, 2014. In the second quarter of fiscal 2012, we settled one of the
foreign  currency  forward  contracts  for  U.S.  $3.9  million.  Our  objective  is  to  eliminate  variability  of  our
cash flows on the amount of interest income we receive on the promissory note from changes in foreign
currency exchange rates. These contracts were designated as cash flow hedges. Accordingly, changes in the
fair value of the contracts are recorded in ‘‘Other comprehensive income’’. The fair value and the change
in  the  fair  value  were  not  material  for  fiscal  2012,  2011  and  2010.  No  gains  or  losses  were  recognized  in
earnings as these contracts were deemed to be effective  hedges.

Debt. The fair value of long-term debt was determined using the present value of future cash flows
based  on  the  borrowing  rates  currently  available  for  debt  with  similar  terms  and  maturities  (Level  2
measurement as described in Note 2, ‘‘Basis of Presentation and Preparation’’). The carrying value of our
long-term debt approximates fair value at September  30, 2012 and October 2, 2011.

15. Joint Ventures

Consolidated Joint Ventures

The aggregate revenue of the consolidated joint ventures was $19.3 million and $74.3 million for fiscal
2012 and 2011, respectively. The revenue decline resulted from our acquisition of the largest consolidated
joint  venture  in  fiscal  2011,  which  was  related  to  the  BPR  acquisition.  Assets  and  liabilities  of  these
consolidated joint ventures were immaterial at fiscal 2012 and 2011 year-ends. These assets are restricted
for  use  only  by  those  joint  ventures  and  are  not  available  for  our  general  operations.  Cash  and  cash
equivalents at September 30, 2012 and October 2, 2011 were $1.6 million and  $1.0 million, respectively.

Unconsolidated Joint Ventures

We  account  for  the  majority  of  our  unconsolidated  joint  ventures  using  the  equity  method  of
accounting.  Under  this  method,  we  recognize  our  proportionate  share  of  the  net  earnings  of  these  joint
ventures  as  a  single  line  item  under  ‘‘Other  costs  of  revenue’’  in  our  consolidated  statements  of  income.
For fiscal 2012, 2011 and 2010, we reported $2.9 million, $4.9 million and $1.2 million of equity in earnings
of  unconsolidated  joint  ventures,  respectively.  Our  maximum  exposure  to  loss  as  a  result  of  our
investments  in  unconsolidated  VIEs  is  typically  limited  to  the  aggregate  of  the  carrying  value  of  the
investment.  Future  funding  commitments  for  the  unconsolidated  joint  ventures  are  immaterial.  The
unconsolidated joint ventures are, individually and in aggregate, immaterial to our consolidated financial
statements.

The  aggregate  carrying  values  of  the  assets  and  liabilities  of  the  unconsolidated  joint  ventures  were
$19.0 million and $15.7 million, respectively, at September 30, 2012, and $24.0 million and $21.0 million,
respectively, at October 2, 2011.

16. Commitments and Contingencies

We  are  subject  to  certain  claims  and  lawsuits  typically  filed  against  the  engineering,  consulting  and
construction profession, alleging primarily professional errors or omissions. We carry professional liability
insurance, subject to certain deductibles and policy limits, against such claims. However, in some actions,
parties  are  seeking  damages  that  exceed  our  insurance  coverage  or  for  which  we  are  not  insured.  While
management  does  not  believe  that  the  resolution  of  these  claims  will  have  a  material  adverse  effect,
individually  or  in  aggregate,  on  our  financial  position,  results  of  operations  or  cash  flows,  management
acknowledges the uncertainty surrounding the  ultimate resolution of these matters.

In  May  2003,  Innovative  Technologies  Corporation  (‘‘ITC’’)  filed  a  lawsuit  in  Montgomery  County,
for
Ohio  against  Advanced  Management  Technology,  Inc.  (‘‘AMT’’)  and  other  defendants 
misappropriation  of  trade  secrets,  among  other  claims.  In  June  2004,  we  purchased  all  the  outstanding
shares of AMT. As part of the purchase agreement, the former owners of AMT agreed to indemnify us for
all costs and damages related to this lawsuit. In December 2007, the case went to trial and the jury awarded
$5.8  million  in  compensatory  damages  to  ITC.  In  addition,  the  jury  awarded  $17  million  in  punitive

106

TETRA TECH, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

16. Commitments and Contingencies (Continued)

damages  to  ITC  plus  reasonable  attorneys’  fees.  In  July  2008,  the  Common  Pleas  Court  of  Montgomery
County denied AMT’s motion for judgment notwithstanding the verdict and conditionally denied AMT’s
motion for a new trial. Further, the court remitted the verdict to $2.0 million in compensatory damages and
$5.8  million  in  punitive  damages.  ITC  accepted  the  remittitur,  and  AMT  appealed.  The  appellate  court
remanded the matter to the trial court for ruling on ITC’s motion for prejudgment interest and attorneys’
fees. In December 2009, the trial court awarded ITC $2.9 million in attorneys’ fees and costs, and denied
ITC’s  motion  for  prejudgment  interest.  AMT  appealed  the  trial  court’s  decision  awarding  compensatory
and punitive damages, and attorneys’ fees and costs. ITC cross-appealed the trial court’s decision to remit
the  jury  verdict  and  the  trial  court’s  denial  of  prejudgment  interest.  On  October  28,  2011,  the  court  of
appeals issued its decision and affirmed the trial court’s rulings. ITC has filed a motion seeking additional
attorneys’ fees which is pending. In December 2011, AMT appealed the court of appeals decision to the
Ohio Supreme Court which declined to accept the appeal. On April 5, 2012, AMT paid the judgment in
the  amount  of  $14.4  million,  including  all  post-judgment  interest,  in  full.  The  former  owners  of  AMT
honored their indemnification agreement and reimbursed us in full for the amount paid in satisfaction of
the judgment.

On  April  17,  2012,  authorities  in  the  province  of  Quebec,  Canada  charged  two  employees  of  BPR
Triax,  a  subsidiary  of  BPR  Inc.,  and  BPR  Triax,  under  the  Canadian  Criminal  Code  with  allegations  of
corruption.  BPR  Triax  generates  approximately  $7  million  in  annual  revenue.  BPR  Inc.  is  one  of  our
Canadian subsidiaries, headquartered in Quebec City, Quebec. The preliminary hearing for this matter is
scheduled to begin in February 2013. We have conducted an internal investigation concerning this matter
and we believe the allegations are limited to activities at BPR Triax prior to our acquisition of BPR Inc. in
October 2010. The financial impact to us  is unknown at this  time.

17. Reportable Segments

In  the  first  quarter  of  fiscal  2012,  we  implemented  organizational  changes  that  resulted  in  a
realignment of certain operating activities in our reportable segments. This realignment resulted from the
organic growth of new activities in a component of an existing reportable segment due to changing business
conditions.  These  activities  are  not  regularly  reviewed  by  our  Chief  Operating  Decision  Maker  to  assess
performance or make decisions about the resources to be allocated to them and do not individually meet
the definition of a reportable segment. The changes were intended to improve organizational effectiveness
and efficiency by better aligning operations with similar characteristics such as client types, project types,
required  resources  and  financial  metrics.  Prior  year  amounts  have  been  reclassified  to  conform  to  the
current year presentation.

In the fourth quarter of fiscal 2012, we initiated the execution of the reorganization of our operations
to improve future growth and profitability. These activities included the consolidation and realignment of
certain operating activities to improve organizational effectiveness and achieve efficiencies in our segment
management.  We  also  decided  to  exit  certain  unprofitable  business  activities.  Specifically,  this
reorganization included the elimination of the EAS reportable segment effective at the beginning of fiscal
2013.  Operating  activities  previously  reported  in  this  segment  have  been  realigned  with  operations  with
similar client types, project types and financial metrics in the ECS and TSS segments. Segment results on a
prospective basis will be revised consistent with the new organization structure. Prior period amounts will
be restated to conform to the new presentation  beginning  in fiscal 2013.

17. Reportable Segments (Continued)

Our reportable segments were as follows  for  fiscal  2012:

Engineering and Consulting Services. ECS provides front-end science, consulting engineering services
and  project  management  in  the  areas  of  surface  water  management,  solid  waste  management,  mining,
geotechnical sciences, arctic engineering,  industrial  process and oil sands,  and information technology.

Technical Support Services. TSS advises clients through the study, design and implementation phases
of  projects.  TSS  provides  management  consulting  services  and  strategic  direction  in  the  areas  of
environmental  assessments/hazardous  waste  management;  climate  change;  international  development;
international reconstruction and stabilization; energy; oil and  gas; and technical government consulting.

Engineering  and  Architecture  Services. EAS  provides  engineering  and  architecture  design  services,
together  with  technical  and  program  administration  services  for  projects  related  to  water  infrastructure,
transportation, and buildings and facilities. Beginning in fiscal 2013, the EAS operations were re-assigned
to the ECS and TSS business segments. The water and transportation infrastructure services were aligned
with  related  services  in  ECS,  and  the  buildings  and  facilities  activities  were  aligned  with  complementary
energy efficiency and international development services in  TSS.

Remediation  and  Construction  Management. RCM  provides  full-service  support  to  all  of  our  client
sectors  including  the  U.S.  federal  government,  in  the  U.S.  and  internationally,  and  commercial  clients
worldwide. We provide construction and construction management services in the areas of environmental
remediation, infrastructure development, energy, and oil and  gas.

Management  evaluates  the  performance  of  these  reportable  segments  based  upon  their  respective
segment  operating  income  before  the  effect  of  amortization  expense  related  to  acquisitions  and  other
unallocated  corporate  expenses.  We  account  for  inter-segment  sales  and  transfers  as  if  the  sales  and
transfers  were  to  third  parties;  that  is,  by  applying  a  negotiated  fee  onto  the  costs  of  the  services
performed. All significant intercompany  balances  and transactions are eliminated  in consolidation.

18. Quarterly Financial Information  –  Unaudited

In  the  opinion  of  management,  the  following  unaudited  quarterly  data  for  fiscal  years  ended
September 30, 2012 and October 2, 2011 reflect all adjustments necessary for a fair statement of the results
of operations.

In the fourth quarter of fiscal 2012, operating income was adversely impacted by $16.9 million of costs
related  to  the  reorganization  of  our  operations  as  described  in  Note  17,  ‘‘Reportable  Segments.’’  These
costs  included  $6.4  million  of  compensation-related  expenses  for  severance  and  employee  retention.  In
addition, we recorded $4.4 million (see Note 6, ‘‘Property and Equipment’’) of lease exit costs, fixed asset
write-downs  and  other  long-lived  asset  impairments  associated  with  office  space  reductions  and
relocations. Further, we incurred operational losses of $5.2 million for winding down certain India-based
activities  that  are  no  longer  supported  by  our  reorganized  business  model.  We  also  identified  one  small
reporting unit in the EAS segment in which goodwill was impaired that resulted in a $0.9 million non-cash
goodwill  impairment  charge.  Fourth  quarter  fiscal  2012  operating  income  also  included  net  gains  of

Item 9A. Controls and Procedures

Evaluation  of  disclosure  controls  and  procedures  and  changes  in  internal  control  over  financial

reporting

At September 30, 2012, we carried out an evaluation of the effectiveness of the design and operation
of our disclosure controls and procedures. Based on our management’s evaluation (with the participation
of  our  principal  executive  officer  and  principal  financial  officer),  our  principal  executive  officer  and
principal  financial  officer  have  concluded  that,  as  of  the  end  of  the  period  covered  by  this  report,  our
disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act),
were effective.

Management’s Report on Internal Control over Financial  Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over
financial reporting. As defined in Exchange Act Rule 13a-15(f), internal control over financial reporting is
a process designed by, or under the supervision of, our principal executive and principal financial officer
and effected by our Board of Directors, management and other personnel to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of consolidated financial statements for
external purposes in accordance with U.S. GAAP. Internal controls include 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 our assets; (ii) provide reasonable assurance that transactions are recorded
as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with  U.S.  GAAP  and  that  our
receipts and expenditures are being made only in accordance with authorizations of our management and
directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use or disposition of our assets that could have a material effect on our consolidated 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. Accordingly, even effective internal control over financial
reporting can only provide reasonable assurance  of achieving  their control objectives.

Under the supervision and with the participation of our management, including our Chief Executive
Officer  and  Chief  Financial  Officer,  we  assessed  the  effectiveness  of  our  internal  control  over  financial
reporting at September 30, 2012, based on the criteria in Internal Control – Integrated Framework issued by
the  COSO.  Based  upon  this  assessment,  management  has  concluded  that  our  internal  control  over
financial reporting was effective at September  30, 2012, at a reasonable assurance level.

PricewaterhouseCoopers  LLP,  the  independent  registered  public  accounting  firm  that  audited  the
consolidated financial statements included in this Form 10-K, has issued a report on our internal control
over financial reporting. This report, dated  November 14, 2012, appears on page 74 of  this Form 10-K.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the three months ended
September 30, 2012 that have materially affected, or are reasonable likely to materially affect, our internal
control over financial reporting.
