To Our Shareholders

“We are positioned 
for another period 
of sustainable 
performance in 
2007 and beyond.”

Victor L. Richey                 Alyson S. Barclay                Gary E. Muenster                           

A

lthough 2006 was a challenging year for ESCO, our operational performance was consistent 
with the expectations set forth at the beginning of the year, and we were able to success-

fully complete several of our strategic objectives.

A year ago, I discussed our plans within the Communications segment to continue investing 
in  new  product  development,  sales  and  marketing,  software  upgrades,  and  complementary  ac-
quisitions. The investments that we made in 2006, in both technology and acquisition partners, 
have positioned us for significantly improved financial performance in 2007, and should result 
in meaningful sales and earnings growth for the foreseeable future. This growth will provide the 
opportunity to increase long-term shareholder value, which is our primary mission. 

In 2006, we invested nearly $125 million to acquire two companies significantly enhancing our 
Communications segment product offering, and to upgrade our Advanced Metering Infrastructure 
(AMI) software platform that drives our TWACS® electric utility solution. Our strong cash genera-
tion allowed us to make investments of this magnitude and still end the year with $37 million in 
cash and no debt outstanding.

I am convinced that these investments in Communications, coupled with the foundation of our 
core businesses that have successfully driven our historical performance, have positioned us for 
another period of sustainable performance improvement in 2007 and beyond.

My perspective on the current position and outlook for the individual segments of our business 

is as follows:

In the Communications segment, 2006 was a tremendous year for us in terms of positioning 
ESCO for significant growth. This segment offers us the best opportunity to deliver meaningful 
increases in shareholder value over the next few years.

In February 2006, we acquired Hexagram, Inc., a market leader in providing fixed network radio 
frequency (RF) based automatic meter reading solutions to utility customers across the United 
States. Prior to the addition of Hexagram, ESCO’s product offering was primarily devoted to elec-
tric utility customers through its market leading TWACS technology. With Hexagram, we not only 
acquired one of the best technologies available, but we also doubled the size of our served market 
by gaining direct access to gas and water utilities.

“In addition to 
acquiring excel-
lent companies 
and technologies, 
we have added 
strong manage-
ment teams.”

To Our Shareholders (Continued)

Earlier in fiscal 2006, we acquired Nexus Energy Software, a leading provider of sophisticated 
meter data management software solutions serving over 85 utilities worldwide. Nexus’ application 
software enables a utility to better manage its operations through energy management, energy 
forecasting, distribution asset optimization, and revenue assurance. In addition, Nexus’ products 
significantly enhance a utility’s customer service by providing a seamless interface through the 
use of “customer-facing” software packages which allow consumers to view their individual usage 
patterns and have a better understanding of their consumption and billing structure. 

We are very pleased that in addition to acquiring excellent companies with solid technologies 
and future market opportunities, we also added strong leadership and management teams with a 
tremendous amount of industry knowledge and experience. 

In addition to the acquisitions, we have invested and will continue to invest at DCSI where 
we have introduced several new products and are developing a state-of-the-art software upgrade 
known as TWACS Next Generation, or TNG. We strongly believe that TNG, with its significantly 
enhanced speed, bandwidth and functionality, will be the best available solution to handle even 
the most complex AMI requirements. 

Our  new  product  development,  in  conjunction  with  TNG,  has  been  focused  on  meeting  the 
needs of our existing and future customers and includes several products that will provide func-
tionality “behind the meter.” These new products include interfaces with smart thermostats and 
multiple-function in-home displays which will allow utilities and their customers to manage how 
and when energy is used. Our full suite of products produces the information necessary to allow 
the utilities to gain greater insight into and better control over the management of their energy 
resources, which is the core tenet of AMI. 

In the Test segment, we continue to see above average growth prospects as the introduction 
of new electronic products and new testing standards continues at an unprecedented pace. My 
confidence in our ability to capture a majority of this growth is based on our leadership position, 
expanding international presence, and superior technology. 

This segment continues to earn better than average returns on invested capital and therefore, 
we will continue to invest to both expand our product offering and to extend our international 
reach,  especially  in  Asia.  Electronics  manufacturers  are  establishing  new  product  development 
centers in the Far East, and we will continue to expand our presence near these customers to 
capture this growing demand. Additionally, we remain committed to managing our cost structure 
in this segment to better leverage our growth. 

In  Filtration,  we  expect  continued  solid  financial  performance  although  our  growth  outlook 
remains somewhat modest. Our Filtration segment continues to provide a foundation for our busi-
ness and is a significant cash generator. Although we have pockets of growth in aerospace and 
medical, the aggregate growth prospects are somewhat muted by our automotive and industrial 
content. As such, we will remain selective in our investment decisions and will be heavily focused 
on improving the returns from our existing operations.

Overall, I believe we have the financial strength and flexibility, as well as the right products and 
technologies, to effectively achieve our growth plans in 2007 and beyond.  I am grateful that we 
have solid management teams in place across the Company who understand our mission and are 
fully committed to delivering exceptional results.

In closing, I want to thank our customers for the opportunity to serve them, our employees 
for their effort and dedication, our Board of Directors for their leadership and guidance, and our 
shareholders for their support and confidence.

DCSI Provides Its 
Reliable TWACS 
Equipment. Utilities 
install the Two Way 
Automatic Communication 
System (TWACS) alongside 
their existing electrical 
system. TWACS equipment 
in each substation routes 
messages from the utility 
office along the power 
lines to the TWACS 
transponder in the meter. 

Since the TWACS message 
passes through transform-
ers, regulators, and other 
equipment, utilities enjoy 
a system that is straight-
forward to install and 
manage. As new homes  
are connected to the 
electrical grid, TWACS 
expands as well. When 
outages occur, utilities 
with TWACS can easily 
verify which customers  
are without power.

DCSI Leads with In-
Home Display Device.  
To meet the emerging 
need for utilities 
to provide usable 
end-customer in-
formation, DCSI has 
led the way with a

Innovative Antenna 
Design Is Key to 
Successful Testing. 
Antennas are a critical 
component in any RF 
measurement system. 
The type of antenna 
required is determined 
by the test frequency 
and methodology. As 

the leading supplier of 
measurement antennas, 
ETS-Lindgren continues 
to bring innovation with 
new antenna designs 
which offer custom-
ers both improved RF 
performance as well as 
improved look and feel.

before going to market. 
ETS-Lindgren actively 
works with a number 
of wireless groups to 
develop test standards 
addressing both existing 
technologies as well  
as emerging wireless 
technologies such  
as Wi-Fi, WiMax and  
UWB (ultra wide band). 
ETS-Lindgren has pro-
vided more OTA test 
facilities than anyone.  

ETS-Lindgren Pro-
vides OTA (Over-the-
Air) Wireless Test 
Systems. Customers 
expect dependable 
connections and quality 
service when using wire-
less devices. To achieve 
maximum performance, 
wireless devices must 
be designed to optimize 
signal strength, signal 
directionality and device 
sensitivity. ETS-Lindgren 
provides products and 
turnkey systems needed 
by design engineers to

Automotive Test-
ing Is Needed to Meet 
Specific Standards. 
All products containing 
electronics must meet 
specific EM (electro-
magnetic) emission and 
immunity standards. 
The automotive industry 

has developed 
additional standards for 
both component and 
vehicle manufacturers. 
ETS-Lindgren’s triplate 
is just one of many 
products supplied to the 
automotive industry that 
enables manufacturers to 
meet these standards. 

Wireless Positioning 
Systems Are Provided 
by ETS-Lindgren. 
Manufacturers testing 
wireless devices need to 
know the signal strength 
and pattern of the 
device they are develop-
ing. In addition, this 
measurement must  be 

done at various angles 
of the device, creating 
a 3D pattern. ETS-
Lindgren provides both 
the positioning 
equipment and 
the software 
required to do 
these types of 
measurements.

MRI Interventional 
Suite Is an Emerging 
Market. An interven-
tional suite provides 
magnetic shielding in a 
sterile environment. A 
sterile and shielded en-
vironment is significant 
because it allows an MR 
scan to be performed dur-
ing a surgical procedure, 
eliminating the need to 
move the patient and 

potentially eliminating 
the need for multiple 
surgeries. ETS-Lindgren 
provides customers with 
all the critical com-
ponents of the room, 
including the specialized 
automatic sliding door. 
As the leading supplier of 
shielding to the MR mar-
ket, this new application

Commitment to Communities

D

uring 2006, the Company established the ESCO Technologies Foundation, a public 

charity whose primary focus is to assist children and families in need, primarily in 

communities where the Company has operations. The Foundation will also grant scholar-

ships to eligible children of ESCO employees. Throughout 2006, the Foundation provided 

financial assistance to a number of organizations, some of which are described below.

Our Little Haven (OLH) 
is a St. Louis-based charity 
dedicated to creating a com-
munity where children are 
cherished. The Foundation’s 
grant was used for OLH’s 
new therapeutic preschool 
program, Our Little Academy. 
The Foundation also provid-
ed OLH’s school age children 
with clothing and school 
supplies needed for their 
upcoming school year. Dur-
ing the holiday season, cor-
porate employees purchased 
toys and clothing, fulfilling 
the wish list of each child in 
residence at OLH.

Habitat for Humanity 
is a national organization 
whose goal is to eliminate 
substandard housing by 
building homes for families 
who might not otherwise be 
able to afford one. Construc-
tion is done with assistance 
from volunteers and the 
family who will occupy 
each house. This year, the 
Foundation contributed to 
Habitat homes being built 
in three locations: St. Louis, 
Missouri; McHenry County, 
Illinois and DuPage, Illinois. 

In addition to the Founda-
tion’s financial contribution, 
a number of DCSI and corpo-
rate employees participated 
this past summer in the 
construction of a house in 
the JeffVanderLou neighbor-
hood of St. Louis. 

Port Hueneme South 
Oxnard Neighborhood 
for Learning in Oxnard, 
California was the recipient 
of a grant from the Founda-
tion to provide funds for the 
district’s mini-grant program 
which supports the preschool 
experience for children in 
the South Oxnard region 
whose parents may be strug-
gling to afford preschool.

Any Baby Can, in the 
Austin, Texas area, received 
a grant from the ESCO 
Foundation to further its 
mission of ensuring that 
children reach their potential 
through education, therapy 
and family support services. 
During the year, several 
employees from ETS-Lindgren 
in Cedar Park, Texas, held 
a fund-raising event where 
additional funds were raised 
for this organization.

Revitalization 2000, 
Inc., focused on the 
Ville Neighborhood of 
North St. Louis, was 
the recipient of a grant 
from the Foundation in 
support of its work-
training and leadership 
programs in collabora-
tive efforts with DeLaSalle 
Middle School and Northside 
Community Center. In ad-
dition, several employees 
from the Company’s DCSI 
subsidiary participated in 
the organization’s robotics 
engineering program. These 
employees taught robotics 
to DeLaSalle students and 
prepared them for “Botball,” 
a regional robotics com-
petition at Rose-Hulman 
Institute of Technology in 
Terre Haute, Indiana.

As the ESCO Technologies 
Foundation continues to 
grow, it will be able to 
extend its reach to even 
more charities in need. We 
are very excited about the 
new Foundation and the

Report of the Chief Financial Officer

Fiscal 2006 was a year of significant strategic accomplishment for 
our Company in spite of facing some challenging end-market issues 
at a few of our operating units. 

At the start of the year, we outlined our 2006 financial goals and 
objectives, anticipating relatively flat sales and lower EPS primarily 
as a result of decreased sales of high margin defense spares and 
video security products. The decrease in projected EPS was also 
driven by additional investments in engineering, program manage-
ment, and new product development at our Advanced Metering 
(AMI) subsidiaries to support our long-term growth objectives.  
Also in 2006, we began expensing stock options and amortizing  
our software development costs. 

Financially, there were a lot of moving parts in 2006 including the 
strategic acquisitions of Nexus and Hexagram, and the large AMI 
contract award at PG&E. We finished 2006 with total revenue, EBIT 
margin, earnings per share, and cash flow generally in line with our 
original expectations. 

Achieving our 2006 financial goals, along with the AMI acquisitions 
and the ramp-up of PG&E, will allow us to continue to increase our 
financial flexibility in support of our strategic growth alternatives 
during fiscal 2007 and beyond. 

To recap 2006, we grew total revenues by 7 percent, with the larg-
est increase coming from our Communications segment which grew 
by 13 percent as a result of the acquisitions. The Test business in-
creased sales by 8 percent as this segment’s worldwide end markets 
continue to show strength. Filtration revenues increased slightly in 
spite of the significant decrease in defense spares compared to the 
prior year.

EBIT (1) was lower in 2006 compared to 2005 due to the decreased 
sales of defense spares and video security products, changes in the 
sales mix of AMI products, along with stock option expensing and 
software amortization. Our consolidated EBIT margin (EBIT dollars 
as a percent of sales) was 10.4 percent in 2006, versus 14.4 percent 
in 2005. EBIT margins were 11.2 percent in Filtration, 11.6 percent 
in Test, and 18.1 percent in Communications.

EPS was $1.19 in 2006 versus $1.66 in 2005 reflecting the impact 
of the lower EBIT contributions described above.

At September 30, 2006, we had $37 million of cash and no debt 
outstanding, compared to the start of the year, when we had $105 
million of cash. The $68 million net decrease in cash during 2006 
reflects the $92 million spent on acquisitions, the $37 million spent 
on capital equipment and software upgrades, net of the $61 million 
of cash generated.

On the Governance front, ESCO has a long history of maintain-
ing strong internal financial controls and rigorous management 
oversight and we are very proud to say that we remain in full 
compliance with the Sarbanes-Oxley Act as of September 30, 2006. 
We continue to devote significant efforts across all operating units 
to test our financial control systems. These efforts not only fulfill 
our obligations under the Act, but reinforce the strong internal 
control environment that has long been a part of our operating 
culture. When reviewing our external communications, it should 
be apparent that full and proper disclosure remains a key part of 
our management style, and we intend to continue to be a leader 
in transparent financial reporting and adherence to the highest 
ethical standards. 

We remain steadfastly committed to delivering shareholder value 
and are confident that we have the right business platform, product 
portfolio, cost structure, growth strategies, and financial flexibility 
to make ESCO a compelling investment for the foreseeable future.

Management’s Discussion and Analysis

The following discussion should be read in conjunction with the 
consolidated financial statements and notes thereto. The years 
2006, 2005 and 2004 represent the fiscal years ended September 30, 
2006, 2005 and 2004, respectively, and are used throughout the 
document. During 2005, the Company had a 2-for-1 stock split 
which was effected as a 100 percent stock dividend and was paid 
on September 23, 2005 to shareholders of record as of September 9, 
2005. The 2004 common stock and per share amounts have been 
adjusted to reflect the stock split.

introduction

The $18.2 million or 13.2% increase in net sales in 2006 as  
compared to the prior year was due to: Hexagram and Nexus sales of 
$18.6 million and $9.6 million, respectively; partially offset by an 
$8.6 million decrease in sales of Comtrak’s video security products; 
and $1.5 million of lower shipments of DCSI’s AMR products.

The $1.5 million decrease in sales of DCSI’s AMR products in 
2006 as compared to 2005 was due to: an increase in sales to 
TXU of $19.9 million and other investor owned utilities (IOUs) 
of $3.0 million; offset by $16.2 million of lower AMR product 
sales to the electric utility cooperative (COOP) market due to the 
decrease in orders received during the second half of fiscal 2005; 
and an $8.1 million decrease in sales to Puerto Rico Electric Power 
Authority (PREPA) as the contract nears completion.

Comtrak’s sales were $7.5 million, $16.1 million, and $5.6 million 
in 2006, 2005 and 2004, respectively. The decrease in sales in  
2006 as compared to the prior year was due to an acceleration of 
shipments in 2005 to meet the customer’s schedule. The increase  
in sales in 2005 versus 2004 was due to a delay in deliveries in 
2004 as a result of a significant customer requesting Comtrak to 
modify its software operating system to provide enhanced “virus” 
protection within the product. 

The $0.2 million or 0.1% increase in Communications net sales  
in 2005 as compared to the prior year was due to $10.5 million  
of higher shipments of SecurVision® products. This increase was 
almost entirely offset by a $10.3 million decrease in sales of AMR 
products. The decrease in sales of AMR products in 2005 versus 
2004 was mainly due to the wind-down of a contract with PPL 
Electric Utilities Corporation (PPL). Sales to PPL decreased 
$19.3 million in 2005 to $2.4 million from $21.6 million in 2004. 
Sales to other IOUs, such as Bangor Hydro-Electric Company,  
Idaho Power Company, and PREPA decreased $17.9 million in 2005 
versus 2004, and were partially offset by $7.2 million in sales to 
TXU and $19.8 million of additional sales to the COOP market and 
other customers. 

Effective February 1, 2006, the Company acquired the capital stock 
of Hexagram for a purchase price of approximately $66 million. The 
acquisition agreement also provides for contingent consideration 
of up to $6.3 million over a five year period following the acqui-
sition if Hexagram exceeds certain sales targets. Hexagram is a 
radio-frequency (RF) fixed network AMR company headquartered in 
Cleveland, Ohio. Hexagram broadens the Company’s served market 
and provides an RF based AMI system serving primarily gas and 
water utilities. Hexagram’s annual revenue over the past three years 
has been in the range of $20 million to $35 million. The operating 
results for Hexagram, since the date of acquisition, are included 
within the Communications unit. The Company recorded approxi-
mately $51 million of goodwill and $3.5 million of trademarks as a 
result of the transaction. The Company also recorded $6.6 million 
of identifiable intangible assets consisting primarily of patents and 
proprietary know-how, customer contracts, and order backlog which 
are being amortized on a straight-line basis over periods ranging 
from six months to seven years. 

Effective November 29, 2005, the Company acquired Nexus  
through an all cash for shares merger transaction for approximately 
$29 million in cash plus contingent cash consideration over the 
four year period following the merger if Nexus exceeds certain 
sales targets. Nexus is a software company headquartered in 
Wellesley, Massachusetts with annual revenues of approximately 
$10 million. Nexus broadens the Company’s served market and 
provides software solutions that allow utilities to fully utilize the 
information produced by the Company’s AMI systems. The operating 
results for Nexus, since the date of acquisition, are included within 
the Communications unit. The Company recorded approximately 
$24 million of goodwill as a result of the transaction. The Company 
also recorded $2.7 million of identifiable intangible assets consisting 
of customer contracts and backlog value which are being amortized 
on a straight-line basis over periods ranging from one year to  
three years. 

All of the Company’s acquisitions have been accounted for using 
the purchase method of accounting, and accordingly, the respective 
purchase prices were allocated to the assets (including intangible 
assets) acquired and liabilities assumed based on estimated fair 
values at the date of acquisition. The financial results from these 
acquisitions have been included in the Company’s financial  
statements from the date of acquisition.

Management’s Discussion and Analysis

Filtration/Fluid Flow

Net sales in 2006 increased $2.4 million or 1.4% compared to 2005 
primarily as a result of higher commercial aerospace shipments at 
PTI of $5.6 million, a net sales increase at Filtertek of $3.3 million 
driven by higher commercial shipments, partially offset by lower 
defense spares and T-700 shipments at VACCO of $6.6 million. 

Net sales in 2005 decreased $2.2 million or 1.3% compared to 2004 
primarily as a result of lower defense spares shipments at VACCO of 
$4.3 million, a net sales decrease at Filtertek of $0.5 million driven 
by lower automotive shipments, partially offset by higher commercial 
and military aerospace shipments at PTI of $2.6 million. 

Test

The net sales increase of $9.2 million or 7.7% in 2006 as 
compared to the prior year was mainly due to: a $10.2 million 
increase in net sales from the Company’s U.S. operations driven 
by sales of additional test chambers and higher component sales, 
a $0.6 million increase in net sales from the Company’s Asian 
operations; partially offset by a $1.6 million decrease in net sales 
from the Company’s European operations due to the prior year 
completion of several test chamber projects.

The net sales increase of $9.0 million or 8.2% in 2005 as compared 
to 2004 was mainly due to: an $11.5 million increase in net sales 
from the Company’s U.S. operations driven by the successful 
completion of the design on a large aircraft chamber project, 
additional test chamber installations, higher component sales, 
and the installation of several government shielding projects; a 
$4.3 million increase in sales from the Company’s Asian operations; 
partially offset by a $6.9 million decrease in net sales from the 
Company’s European operations due to the completion of two large 
test chamber projects in 2004.

ORDERS AnD BACKlOg

New orders received in 2006 were $479.2 million, resulting in an 
order backlog of $253.4 million at September 30, 2006 as compared 
to an order backlog of $233.1 million at September 30, 2005. In 
2006, the Company recorded $187.5 million of new orders related 
to Communications products (including $19.0 million of new 
orders and $6.0 million of acquired backlog from Hexagram and 
$16.7 million of new orders and $9.0 million of acquired backlog 
from Nexus), $172.1 million related to Filtration products, and 
$119.6 million related to Test products. 

Within the Communications segment, DCSI received $129.3 million, 
$105.1 million and $106.3 million of new orders for its AMR 
products in 2006, 2005 and 2004, respectively. DCSI received 
$19.2 million of new orders from TXU in 2006. In addition, in 
November 2005, DCSI signed an agreement to provide equipment, 
software and services to PG&E with a potential contract value of up 
to approximately $310 million covering up to five million electric 
endpoints over a five-year deployment period beginning in 2007. 
DCSI received orders totaling $4.2 million from PG&E under this 
agreement during 2006. Also, in November 2005, Hexagram entered 
into a contract to provide equipment, software and services to 
PG&E in support of the gas utility portion of PG&E’s AMI project. 
The total potential contract revenue from commencement through 
the five-year full deployment is up to approximately $225 million. 
Hexagram received orders totaling $0.7 million from PG&E under 
this agreement during 2006. See further discussion under “Pacific 
Gas & Electric.” 

In 2005, the Company recorded $117.2 million of new orders related 
to Communications products, $174.4 million related to Filtration 
products, and $121.5 million related to Test products. 

SElling, gEnERAl AnD ADMiniSTRATiVE EXpEnSES

Selling, general and administrative expenses (SG&A) were 
$106.9 million, or 23.3% of net sales in 2006, $84.2 million,  
or 19.6% of net sales in 2005, and $77.3 million, or 18.3% of  
net sales in 2004. 

The increase in SG&A expenses in 2006 as compared to the prior 
year was primarily due to: $7.5 million of SG&A expenses related  
to Nexus; $6.8 million of SG&A expenses related to Hexagram;  
$2.3 million of stock option expense and higher costs related to 
engineering and new product development.

The increase in SG&A expenses in 2005 as compared to 2004 
was primarily due to an increase of $4.9 million associated with 
engineering, marketing and new product development within the 
Communications segment in pursuit of the IOU market. 

AMORTiZATiOn OF inTAngiBlE ASSETS

Amortization of intangible assets was $6.9 million in 2006, 
$2.0 million in 2005 and $2.1 million in 2004. Amortization of 
intangible assets in 2006 included $2.7 million of amortization 
of acquired intangible assets related to the Hexagram and Nexus 
acquisitions, as described in Note 2 to the Consolidated Financial 
Statements. The amortization of acquired intangible assets related 
to Hexagram and Nexus are included in the Corporate operating 
segment’s results. The remaining amortization expenses consist of 
other identifiable intangible assets (primarily software, patents and 
licenses). In March 2006, the Company began amortizing DCSI’s TNG 
software and during 2006, the Company recorded $2.2 million of 
amortization related to its TNG software.

(income) and expenses, net, in 2006 consisted primarily of the 
following items: $(1.8) million non-cash gain representing the 
reversal of a liability related to an indemnification obligation with 
respect to a previously divested subsidiary; $(2.3) million of royalty 
income; partially offset by a $0.2 million charge related to the 
termination of a subcontract manufacturer.

Other (income) and expenses, net, in 2005 consisted primarily  
of: $(2.2) million of royalty income; and a $0.5 million charge 
related to the termination of a supply agreement with a medical 
device customer.

Other (income) and expenses, net, in 2004 consisted primarily  
of: $0.8 million of exit costs related to the Puerto Rico facility;  
a $(0.6) million gain from the settlement of a claim related to  
a former defense subsidiary divested in 1999; and a $0.4 million 
charge for the settlement of a claim involving a former defense 
subsidiary divested in 1996. 

ASSET iMpAiRMEnT — 2005

In June 2005, the Company abandoned its plans to commercialize 
certain sensor products within the Filtration/Fluid Flow segment. 
This action resulted in an asset impairment charge of $0.8 million 
to write off certain patents and a related licensing agreement 
to their respective fair market values. The Company ended its 
development efforts on this program after it determined that 
the market was not developing as quickly as anticipated and the 
expected costs and time frame to fully commercialize the products 
were not acceptable.

EARningS BEFORE inTEREST AnD TAXES (EBiT)

The Company evaluates the performance of its operating segments 
based on EBIT, which the Company defines as earnings from  
continuing operations before interest and taxes. 

EBIT is not a defined GAAP measure. However, the Company believes 
that EBIT provides investors and Management with a valuable and 
alternative method for assessing the Company’s operating results. 
Management evaluates the performance of its operating segments 
based on EBIT and believes that EBIT is useful to investors to 
demonstrate the operational profitability of the Company’s business 
segments by excluding interest and taxes, which are generally 
accounted for across the entire company on a consolidated basis. 
EBIT is also one of the measures Management uses to determine 
resource allocations and incentive compensation.

The decrease in EBIT in 2006 as compared to 2005 was due to: a 
$7.8 million decrease at DCSI due to changes in product mix (IOU 
vs. COOP), charges related to a terminated subcontract manufactur-
er, warranty costs and amortization of TNG software; a $3.8 million 
decrease at Comtrak due to lower shipments; a $0.7 million loss at 
Nexus due to the timing of customer deployments and additional 
SG&A spending related to engineering and new product initiatives; 
partially offset by a $1.8 million contribution from Hexagram.

The increase in EBIT in 2005 as compared to the prior year was 
due to: a $4.6 million increase at Comtrak due to significantly 
higher shipments; partially offset by a $4.2 million decrease at 
DCSI, which continued to increase its engineering and new product 
development expenditures in order to accommodate the growth in 
the AMR/AMI markets, and to further differentiate its technology 
from the competition.

Filtration/Fluid Flow

EBIT decreased in 2006 as compared to 2005 primarily due to: a 
$4.3 million decrease at VACCO due to significantly lower defense 
spares shipments; a $1.4 million decrease at Filtertek partially due 
to increasing raw material costs on petroleum based resins; partially 
offset by a $2.8 million increase at PTI due to higher shipments  
of aerospace products. The 2005 operating results for Filtertek 
included a $1.9 million gain related to the termination of a supply 
agreement with a medical device customer that was not repeated

EBIT increased in 2005 as compared to the prior year primarily 
due to: a $2.5 million increase at Filtertek, which included a 
$1.9 million gain related to the termination of a supply agreement 
with a medical device customer; a $1.4 million increase at PTI due 
to higher shipments of aerospace products; partially offset by the 
$0.8 million asset impairment charge at PTI; and a $3.3 million 
decrease at VACCO due to significantly lower defense spares 
shipments. In 2005, Filtertek experienced an increase in its  
raw material costs on petroleum based resins which negatively 
impacted EBIT. 

Test

The increase in EBIT in 2006 as compared to the prior year was 
mainly due to: a $2.1 million increase in EBIT from the Company’s 
U.S. operations driven by sales of additional test chambers and 
higher component sales, a $0.4 million increase in EBIT from the 
Company’s European operations, and a $0.3 million increase in EBIT 
from the Company’s Asian operations.

EBIT in 2005 included: a $0.9 million increase in EBIT from the 
Company’s U.S. operations driven by favorable changes in sales mix 
resulting from additional sales of antennas and other components 
partially offset by installation cost overruns incurred on certain 
government shielding projects, as well as increased material costs 
for steel and copper.

Corporate

Corporate office operating charges included in consolidated EBIT  
increased by $3.8 million in 2006 as compared to 2005 mainly  
due to: $2.7 million of pre-tax amortization of acquired intangible 
assets related to Nexus and Hexagram; $2.3 million of pre-tax stock 
option expense; partially offset by a $1.8 million non-cash gain 
representing the reversal of a liability related to an indemnifica-
tion obligation with respect to a previously divested subsidiary. 
Corporate office operating charges included in consolidated EBIT 
decreased by $0.4 million in 2005 as compared to 2004. Fiscal 2005 
included an increase of $0.5 million for professional fees and 2004 
included $0.9 million of severance related costs not repeated in 
2005. The “Reconciliation to Consolidated Totals (Corporate)”  
in note 15 to the consolidated financial statements represents 
Corporate office operating charges.

inTEREST inCOME

Interest income was $1.3 million in 2006, $1.9 million in 2005 
and $0.8 million in 2004. The decrease in interest income in 2006 
as compared to 2005 was due to lower average cash balances on 
hand resulting from the 2006 acquisitions. The increase in interest 
income in 2005 as compared to the prior year was due to higher 
average cash balances on hand during the year and a $0.2 million 
refund of look back interest related to income taxes. 

inCOME TAX EXpEnSE

The effective tax rate for continuing operations in 2006 was 36.0% 
compared to 31.9% in 2005 and 37.6% in 2004. The increase in 
the effective tax rate in 2006 as compared to the prior year was 
due to: the effect of the foreign earnings repatriation increased 
2006 income tax expense by $2.4 million and the effective rate by 
4.8%; the adoption of SFAS 123(R) increased tax expense by $0.7 
million and the effective rate by 1.4%; the lower volume of profit 
contributions of the Company’s foreign operations (primarily Puerto 
Rico due to the lower sales to PREPA) adversely impacted the tax 
rate; partially offset by the effect of a favorable change in tax 
contingencies not related to the research tax credit which decreased 
tax expense by $1.4 million and the effective tax rate by 2.9% and 
the net effect of the research tax credit which favorably impacted 
tax expense by $2.5 million and the effective tax rate by 5%. The 
decrease in the effective tax rate for continuing operations in 2005 
as compared to 2004 was due to the timing and volume of profit 
contributions of DCSI’s foreign operations (Puerto Rico), which 
resulted in a 4.6% favorable adjustment to the Company’s foreign 
tax rate differential. 

During 2006, the Company determined that state tax expense had 
not been accurately recorded in the financial statements for years 
2001 through 2005. The effect in any individual prior year was not 
material to the Company’s results of operations, financial position 
or cash flows. The Company adopted the provisions of SEC Staff 
Accounting Bulletin No. 108, “Considering the Effects of Prior Year 
Misstatements when Quantifying Misstatements in Current Year 
Financial Statements” and recorded $2.4 million as a cumulative 
credit adjustment to 2006 beginning retained earnings.

Management’s Discussion and Analysis

Capital Resources and liquidity

Working capital (current assets less current liabilities) decreased  
to $131.4 million at September 30, 2006 from $197.2 million at 
September 30, 2005. During 2006, cash and cash equivalents 
decreased $67.7 million, primarily due to the $92 million spent  
on acquisitions. 

The $15.0 million increase in accounts receivable at September 30, 
2006 is mainly due to: $8.3 million related to Nexus and Hexagram; 
and $5.7 million related to the Filtration segment due to timing 
and volume of sales. The $2.3 million increase in inventories at 
September 30, 2006 is mainly due to a $4.4 million increase related 
to Hexagram, partially offset by a $3.8 million decrease at DCSI. 
Accounts payable increased by $10.2 million at September 30, 
2006, of which $3.0 million related to Nexus and Hexagram and 
$4.6 million related to the timing of vendor payments at DCSI. 

Net cash provided by operating activities was $58.6 million,  
$68.6 million and $61.0 million in 2006, 2005 and 2004, respec-
tively. The decrease in 2006 is related to lower net earnings in the 
current year. The increase in 2005 as compared to 2004 is the result 
of higher earnings and lower cash requirements related to MicroSep.

Capital expenditures for continuing operations were $9.1 million, 
$8.8 million and $10.8 million in 2006, 2005 and 2004, respec-
tively. Major expenditures included manufacturing equipment and 
facility modifications used in the Filtration segment. There were no 
commitments outstanding that were considered material for capital 
expenditures at September 30, 2006.

At September 30, 2006, intangible assets, net, of $59.2 million 
included $45.2 million of capitalized software. Approximately  
$40.0 million of the capitalized software balance represents 
external development costs on software development called “TNG” 
within the Communications segment to further penetrate the IOU 
market. TNG is being deployed to efficiently handle the additional 
levels of communications dictated by the size of the service 
territories and the frequency of reads that are required under  
time-of-use or critical peak pricing scenarios to meet the 
requirements of large IOUs. At September 30, 2006, the Company 
had approximately $5 million of commitments related to TNG 
version 1.6.3 which is expected to be spent over the next six 
months. The Company expects to spend up to approximately 
$10 million in fiscal 2007 on TNG. Amortization of TNG is on a 
straight-line basis over seven years and began in March 2006. The 
Company recorded $2.2 million in amortization expense related to 
TNG during 2006.

At September 30, 2006, the Company had an available net 
operating loss (NOL) carryforward for U.S. federal tax purposes  
of approximately $15 million. This NOL will expire between 2019 
and 2025, and will be available to reduce future Federal income  
tax cash payments.

The closure and relocation of the Filtertek Puerto Rico facility was 
completed in March 2004. The Puerto Rico facility is included in 
other current assets with a carrying value of $3.6 million at  
September 30, 2006. The facility is being marketed for sale.

During 2005, the Company reached a settlement in the defense of  
a certain revenue-generating patent used in the Filtration business. 
Under the terms of the agreement, the Company received a cash 
payment of $1.5 million, and in 2005 the Company recognized a 
gain of $0.3 million, after deducting $0.2 million of professional 
fees related to the settlement. The unrecognized gain is being 
recorded on a straight-line basis in Other (income) and expenses, 
net, over the remaining patent life, through 2011.

In 2004, the Company received $2.1 million as final payment on the 
note receivable from the sale of the Riverhead, NY, property which 
was sold in 1999.

pACiFiC gAS & ElECTRiC

In November 2005, DCSI entered into a contract to provide 
equipment, software and services to Pacific Gas & Electric (PG&E) 
in support of the electric portion of PG&E’s Advanced Metering 
Infrastructure (AMI) project. PG&E’s current AMI project plan 
calls for the purchase of TWACS communication equipment for 
up to approximately five million electric customers over a five-
year period after the commencement of full deployment. The 
total anticipated contract value from commencement through 
the five-year full deployment period is expected to be up to 
approximately $310 million. PG&E also has the right to purchase 
additional equipment and services to support existing and new 
customers through the 20-year term of the contract. Equipment 
will be purchased by PG&E only upon issuance of purchase orders 
and release authorizations. PG&E will continue to have the right to 
purchase products or services from other suppliers for the electric 
portion of the AMI project. On July 20, 2006, the California Public 
Utilities Commission approved PG&E’s AMI project. DCSI has agreed 
to deliver to PG&E versions of its newly developed TNG software 
as they become available and are tested. Delivery of the final 
version for which DCSI has committed is currently anticipated in 
the fourth quarter of fiscal 2007. In accordance with U.S. generally 
accepted accounting standards, the Company will defer all revenue 
related to the DCSI arrangement until all software is delivered 
and acceptance criteria have been met. The contract provides for 
liquidated damages in the event of DCSI’s late development or 
delivery of hardware and software, and includes indemnification 
and other customary provisions. The contract may be terminated 
by PG&E for default, for its convenience and in the event of a force 
majeure lasting beyond certain prescribed periods. The Company 
has guaranteed the obligations of DCSI under the contract. If PG&E 
terminates the contract for its convenience, DCSI will be entitled to 
recover certain costs. 

Management’s Discussion and Analysis

In November 2005, Hexagram entered into a contract to provide 
equipment, software and services to PG&E in support of the 
gas utility portion of PG&E’s AMI project. The total anticipated 
contract revenue from commencement through the five-year full 
deployment is expected to be approximately $225 million. As with 
DCSI’s contract with PG&E, equipment will be purchased only upon 
issuance of purchase orders and release authorizations, and PG&E 
will continue to have the right to purchase products or services 
from other suppliers for the gas utility portion of the AMI project. 
On July 20, 2006, the California Public Utilities Commission 
approved PG&E’s AMI project. The contract provides for liquidated 
damages in the event of late deliveries, includes indemnification 
and other customary provisions, and may be terminated by PG&E 
for default, for its convenience and in the event of a force majeure 
lasting beyond certain prescribed periods. The Company has 
guaranteed the performance of the contract by Hexagram. 

DiVESTiTuRES

Effective April 2, 2004, the Company completed the sale of PTI 
Advanced Filtration Inc. (Oxnard, California) and PTI Technologies 
Limited (Sheffield, England) to domnick hunter group plc for  
$18.0 million in cash. On June 8, 2004, the Company completed 
the sale of PTI S.p.A. (Milan, Italy) to a group of investors 
comprised of the subsidiary’s senior management for $5.3 million. 
An after-tax gain of $1.6 million related to the sale of these 
MicroSep businesses is reflected in the Company’s 2004 results in 
discontinued operations. These businesses are accounted for as a 
discontinued operation in accordance with SFAS 144, “Accounting 
for the Impairment or Disposal of Long-Lived Assets,” and 
accordingly, amounts in the financial statements and related  
notes for 2004, reflect discontinued operations presentation. 

BAnK CREDiT FACiliTY

Effective October 6, 2004, the Company entered into a $100 million 
five-year revolving bank credit facility with a $50 million increase 
option that has a final maturity and expiration date of October 6, 
2009. The credit facility is available for direct borrowings and/or 
the issuance of letters of credit, and is provided by a group of six 
banks, led by Wells Fargo Bank as agent.

The credit facility requires, as determined by certain financial 
ratios, a commitment fee ranging from 17.5 to 27.5 basis points 
per annum on the unused portion. The terms of the facility provide 
that interest on borrowings may be calculated at a spread over 
the LIBOR or based on the prime rate, at the Company’s election. 
The credit facility is secured by the unlimited guaranty of the 
Company’s material domestic subsidiaries and a 65% pledge of the 
material foreign subsidiaries’ share equity. The financial covenants 
of the credit facility include limitations on leverage, minimum 
consolidated EBITDA and minimum net worth. 

At September 30, 2006, the Company had approximately $99.2 mil-
lion available to borrow under the credit facility in addition to  
its $36.8 million cash on hand. At September 30, 2006, the Com-
pany had no borrowings, and outstanding letters of credit of  
$1.5 million ($0.8 million outstanding under the credit facility).  
As of September 30, 2006, the Company was in compliance with  
all bank covenants.

Cash flow from operations and borrowings under the bank credit 
facility are expected to provide adequate resources to meet the 
Company’s capital requirements and operational needs for the 
foreseeable future.

an open market common stock repurchase program for up to  
1.2 million shares, subject to market conditions and other factors 
which covers the period through September 30, 2008. There were 
no stock repurchases during fiscal 2006. The Company repurchased 
670,072 and 312,400 shares in 2005 and 2004, respectively, under 
a previously authorized program.

Critical Accounting policies

The minimum cash funding requirements related to the Company’s 
defined benefit pension plans are zero in 2007, approximately  
$1 million in 2008 and approximately $1 million in 2009. The  
Company made a voluntary cash contribution of $1.4 million  
in 2006.

OThER

Management believes that, for the periods presented, inflation has 
not had a material effect on the Company’s results of operations. 

The Company is currently involved in various stages of investigation 
and remediation relating to environmental matters. Based on 
current information available, Management does not believe the 
aggregate costs involved in the resolution of these matters will 
have a material adverse effect on the Company’s operating results, 
capital expenditures or competitive position.

Market Risk Analysis

MARKET RiSK EXpOSuRE

Market risks relating to the Company’s operations result primarily 
from changes in interest rates and changes in foreign currency 
exchange rates. 

At September 30, 2006 and 2005, the Company had no obligations 
related to interest rate swaps. During 2004, in conjunction with 
the sale of PTI S.p.A., the Company repaid its $8.0 million Euro-
denominated debt, and at the same time, the Company terminated 
its $5.0 million interest rate swap obligation, resulting in a cash 
payment of $0.1 million by the Company. 

The Company is also subject to foreign currency exchange rate risk 
inherent in its sales commitments, anticipated sales, anticipated 
purchases and assets and liabilities denominated in currencies other 
than the U.S. dollar. The foreign currency most significant to the 
Company’s operations is the Euro. Net sales to customers outside  
of the United States were $103.0 million, $103.8 million, and  
$91.5 million in 2006, 2005 and 2004, respectively. The Company 
hedges certain foreign currency commitments by purchasing foreign 
currency forward contracts. The estimated fair value of open forward  
contracts at September 30, 2006 was not material.

The preparation of financial statements in conformity with GAAP 
requires Management to make estimates and assumptions in certain 
circumstances that affect amounts reported in the accompanying 
consolidated financial statements. In preparing these financial 
statements, Management has made its best estimates and judgments 
of certain amounts included in the financial statements, giving due 
consideration to materiality. The Company does not believe there 
is a great likelihood that materially different amounts would be 
reported under different conditions or using different assumptions 
related to the accounting policies described below. However, 
application of these accounting policies involves the exercise of 
judgment and use of assumptions as to future uncertainties and, 
as a result, actual results could differ from these estimates. The 
Company’s senior Management discusses the critical accounting 
policies described below with the Audit and Finance Committee  
of the Company’s Board of Directors on a periodic basis.

The following discussion of critical accounting policies is intended 
to bring to the attention of readers those accounting policies which 
Management believes are critical to the Consolidated Financial 
Statements and other financial disclosure. It is not intended to  
be a comprehensive list of all significant accounting policies  
that are more fully described in Note 1 of Notes to Consolidated 
Financial Statements.

REVEnuE RECOgniTiOn

Communications Unit: Within the Communications unit, 
approximately 95% of the unit’s revenue arrangements 
(approximately 30% of consolidated revenues) contain software 
components. Revenue under these arrangements is recognized  
in accordance with Statement of Position 97-2 (SOP 97-2), 
“Software Revenue Recognition,” as amended by SOP 98-9, 
“Modification of SOP 97-2, Software Revenue Recognition, with 
Respect to Certain Transactions.” The application of software 
revenue recognition requires judgment, including the determination 
of whether a software arrangement includes multiple elements 
and estimates of the fair value of the elements, or vendor-specific 
objective evidence of fair value (“VSOE”). Changes to the elements 
in a software arrangement, and the ability to identify VSOE for 
those elements could materially impact the amount of earned 
and/or deferred revenue. There have been no material changes to 
these estimates for the financial statement periods presented and 
the Company believes that these estimates generally should not be 
subject to significant variation in the future. The remaining 5% of 
the unit’s revenues represent products sold under a single element 
arrangement and are recognized when products are delivered to 
unaffiliated customers.

E S C O   T E C h n O l O g i E S   i n C .   2 0 0 6   A n n u A l   R E p O R T

Management’s Discussion and Analysis

Filtration/Fluid Flow Unit: Within the Filtration/Fluid Flow 
operating unit, approximately 75% of operating unit revenues 
(approximately 30% of consolidated revenues) are recognized when 
products are delivered (when title and risk of ownership transfers) 
or when services are performed for unaffiliated customers. 

Approximately 25% of operating unit revenues (approximately 10% 
of consolidated revenues) are recorded under the percentage-of-
completion provisions of SOP 81-1, “Accounting for Performance of 
Construction-Type and Certain Production-Type Contracts” because 
the Company manufactures complex products for aerospace and 
military customers under production contracts. The percentage-
of-completion method of accounting involves the use of various 
estimating techniques to project costs at completion. These 
estimates involve various assumptions and projections relative 
to the outcome of future events over a period of several years, 
including future labor productivity and availability, the nature and 
complexity of the work to be performed, availability of materials, 
the impact of delayed performance, and the timing of product 
deliveries. These estimates are based on Management’s judgment 
and the Company’s substantial experience in developing these 
types of estimates. Changes in underlying assumptions/estimates 
may adversely affect financial performance if they increase 
estimated project costs at completion, or positively affect financial 
performance if they decrease estimated project costs at completion. 
Due to the nature of these contracts and the operating unit’s cost 
estimating process, the Company believes that these estimates 
generally should not be subject to significant variation in the 
future. There have been no material changes to these estimates for 
the financial statement periods presented. The Company regularly 
reviews its estimates to assess revisions in contract values and 
estimated costs at completion. 

Test Unit: Within the Test unit, approximately 60% of revenues 
(approximately 20% of consolidated revenues) are recognized when 
products are delivered (when title and risk of ownership transfers) 
or when services are performed for unaffiliated customers. Certain 
arrangements contain multiple elements which are accounted for 
under the provisions of EITF 00-21, “Revenue Arrangements with 
Multiple Deliverables.” The application of EITF 00-21 requires 
judgment as to whether the deliverables can be divided into more 
than one unit of accounting and whether the separate units of 
accounting have value to the customer on a stand-alone basis. 
Changes to these elements could affect the timing of revenue 
recognition. There have been no material changes to these elements 
for the financial statement periods presented. 

Approximately 40% of the unit’s revenues (approximately 10% 
of consolidated revenues) are recorded under the percentage-of-
completion provisions of SOP 81-1, “Accounting for the Performance 
of Construction-Type and Certain Production-Type Contracts” due 
to the complex nature of the enclosures that are designed and 
produced under these contracts. As discussed above, this method 
of accounting involves the use of various estimating techniques 
to project costs at completion, which are based on Management’s 
judgment and the Company’s substantial experience in developing 
these types of estimates. Changes in underlying assumptions/
estimates may adversely or positively affect financial performance. 
Due to the nature of these contracts and the operating unit’s cost 
estimating process, the Company believes that these estimates 
generally should not be subject to significant variation in the 
future. There have been no material changes to these estimates for 
the financial statement periods presented. The Company regularly 
reviews its contract estimates to assess revisions in contract values 
and estimated costs at completion. 

inVEnTORY

Inventories are valued at the lower of cost (first-in, first-out) or 
market value. Management regularly reviews inventories on hand 
compared to historical usage and estimated future usage and sales. 
Inventories under long-term contracts reflect accumulated produc-
tion costs, factory overhead, initial tooling and other related costs 
less the portion of such costs charged to cost of sales and any un-
liquidated progress payments. In accordance with industry practice, 
costs incurred on contracts in progress include amounts relating  
to programs having production cycles longer than one year, and  
a portion thereof may not be realized within one year.

inCOME TAXES

The Company operates in numerous taxing jurisdictions and is 
subject to examination by various U.S. Federal, state and foreign 
jurisdictions for various tax periods. Additionally, the Company has 
retained tax liabilities and the rights to tax refunds in connection 
with various divestitures of businesses in prior years. The Company’s 
income tax positions are based on research and interpretations 
of the income tax laws and rulings in each of the jurisdictions in 
which the Company does business. Due to the subjectivity of inter-
pretations of laws and rulings in each jurisdiction, the differences 
and interplay in tax laws between those jurisdictions, as well as the 
inherent uncertainty in estimating the final resolution of complex 
tax audit matters, Management’s estimates of income tax liabilities 
may differ from actual payments or assessments. 

E S C O   T E C h n O l O g i E S   i n C .   2 0 0 6   A n n u A l   R E p O R T 21

Management’s Discussion and Analysis

While the Company has support for the positions taken on its  
tax returns, taxing authorities are increasingly asserting alternate 
interpretations of laws and facts, and are challenging cross  
jurisdictional transactions. Cross jurisdictional transactions 
between the Company’s subsidiaries involving transfer prices for 
products and services, as well as various U.S. federal, state and 
foreign tax matters, comprise the Company’s income tax exposures. 
Management regularly assesses the Company’s position with regard 
to tax exposures and records liabilities for these uncertain tax 
positions and related interest and penalties, if any, according 
to the principles of SFAS No. 5, “Accounting for Contingencies.” 
The Company has recorded an accrual that reflects Management’s 
estimate of the likely outcome of current and future audits. A final 
determination of these tax audits or changes in Management’s 
estimates may result in additional future income tax expense  
or benefit.

At the end of each interim reporting period, Management estimates 
the effective tax rate expected to apply to the full fiscal year. The 
estimated effective tax rate contemplates the expected jurisdiction 
where income is earned, as well as tax planning strategies. Current 
and projected growth in income in higher tax jurisdictions may 
result in an increasing effective tax rate over time. If the actual 
results differ from Management’s estimates, Management may  
have to adjust the effective tax rate in the interim period such 
determination is made.

Income taxes are accounted for under the asset and liability 
method. Deferred tax assets and liabilities are recognized for 
the future tax consequences attributable to differences between 
the financial statement carrying amounts of existing assets and 
liabilities and their respective tax bases. Deferred tax assets and 
liabilities are measured using enacted tax rates expected to apply 
to taxable income in the years in which those temporary differences 
are expected to be recovered or settled. Deferred tax assets may be 
reduced by a valuation allowance if it is more likely than not that 
some portion of all of the deferred tax assets will not be realized. 
The effect on deferred tax assets and liabilities of a change in 
tax rates is recognized in income in the period that includes the 
enactment date. The Company regularly reviews its deferred tax 
assets for recoverability and establishes a valuation allowance when 
Management believes it is more likely than not such assets will not 
be recovered, taking into consideration historical operating results, 
expectations of future earnings, tax planning strategies, and the 
expected timing of the reversals of existing temporary differences.

gOODWill AnD OThER lOng-liVED ASSETS

In accordance with SFAS 142, Management annually reviews 
goodwill and other long-lived assets with indefinite useful lives 
for impairment or whenever events or changes in circumstances 
indicate the carrying amount may not be recoverable. If the 
Company determines that the carrying value of the long-lived asset 
may not be recoverable, a permanent impairment charge is recorded 
for the amount by which the carrying value of the long-lived asset 
exceeds its fair value. Fair value is measured based on a discounted 
cash flow method using a discount rate determined by Management 
to be commensurate with the risk inherent in the Company’s 
current business model. The estimates of cash flows and discount 
rate are subject to change due to the economic environment, 
including such factors as interest rates, expected market returns 
and volatility of markets served. Management believes that the 
estimates of future cash flows and fair value are reasonable; 
however, changes in estimates could result in impairment charges. 
SFAS 142 also requires that intangible assets with estimable useful 
lives be amortized over their respective estimated useful lives to 
their estimated residual values, and reviewed for impairment in 
accordance with SFAS 144.

pEnSiOn plAnS AnD OThER pOSTRETiREMEnT BEnEFiT plAnS

The measurement of liabilities related to pension plans and 
other post-retirement benefit plans is based on Management’s 
assumptions related to future events including interest rates, 
return on pension plan assets, rate of compensation increases, and 
health care cost trend rates. Actual pension plan asset performance 
will either decrease or increase unamortized pension losses that 
will affect net earnings in future years. Depending upon the 
performance of the equity and bond markets in 2007, the Company 
could be required to record a charge to equity. In addition, if the 
discount rate was decreased by 25 basis points from 5.75% to 
5.50%, the accumulated benefit obligation for the defined benefit 
plan would increase by approximately $1.6 million and result in an 
additional after-tax charge to shareholders’ equity of approximately 
$1.0 million. The discount rate used in measuring the Company’s 
pension and postretirement welfare obligations was developed by 
matching yields of actual high-quality corporate bonds to expected 
future pension plan cash flows (benefit payments). Over 500  
Aa-rated, non-callable bonds with a wide range of maturities were 
used in the analysis. After using the bond yields to determine the 
present value of the plan cash flows, a single representative rate 
that resulted in the same present value was developed.

Other Matters

COnTingEnCiES

As a normal incident of the businesses in which the Company 
is engaged, various claims, charges and litigation are asserted 
or commenced against the Company. Lindgren is involved in a 
contract dispute with a prime contractor involving the assertion of 
certain construction delay damages of approximately $3.7 million. 
The project was completed in 2005. Lindgren vigorously denies 
responsibility for this delay and for these damages, and has 
asserted a claim against the prime contractor of $0.9 million 
based on damages suffered by Lindgren. Lindgren continues to 
aggressively defend its position and pursue its right to affirmative 
damages however, there can be no assurance of the outcome at this 
time. In the opinion of Management, final judgments, if any, which 
might be rendered against the Company are adequately reserved, 
covered by insurance, or are not likely to have a material adverse 
effect on its financial statements.

Market risks relating to the Company’s operations result primarily 
from changes in interest rates and changes in foreign currency 
exchange rates. At September 30, 2006 and 2005, the Company  
had no obligations related to interest rate swaps. During 2004,  
in conjunction with the sale of PTI S.p.A., the Company repaid  
its $8.0 million Euro-denominated debt and at the same time, the 
Company terminated its $5.0 million interest rate swap obligation 
resulting in a cash payment of $0.1 million by the Company. See 
further discussion in “Management’s Discussion and Analysis — 
Market Risk Analysis” regarding the Company’s market risks.

The Company carried out an evaluation under the supervision of  
and with the participation of Management, including the Company’s 
Chief Executive Officer and Chief Financial Officer, of the effective-
ness of the design and operation of the Company’s disclosure 
controls and procedures as of the end of the period covered by this 
report. Based upon that evaluation, the Company’s Chief Executive 
Officer and Chief Financial Officer concluded that the Company’s 
disclosure controls and procedures are effective excluding the 
Hexagram and Nexus acquisitions. Disclosure controls and proce-
dures are controls and procedures that are designed to ensure that 
information required to be disclosed in company reports filed or 
submitted under the Securities Exchange Act of 1934 is recorded, 
processed, summarized and reported within time periods specified 
in the Securities and Exchange Commission’s rules and forms. There 
have been no significant changes in the Company’s internal controls 
or in other factors during the period covered by this report that 
have materially affected, or are reasonably likely to materially 
affect those controls and procedures.

new Accounting pronouncements

In December 2004, the FASB issued SFAS No. 123(R), “Share-Based 
Payment” (SFAS 123(R)). This Statement replaces SFAS No. 123, 
“Accounting for Stock-Based Compensation” and supersedes APB 
No. 25, “Accounting for Stock Issued to Employees.” SFAS 123(R) 
requires all stock-based compensation to be recognized as an 
expense in the financial statements and that such cost be measured 
according to the fair value of stock options. The Company adopted 
the provisions of this Statement in the first quarter of fiscal 2006 
on a prospective basis. 

In December 2004, the FASB issued FASB Staff Position FAS 109-2, 
“Accounting and Disclosure Guidance for the Foreign Earnings 
Repatriation Provision within the American Jobs Creation Act of 
2004 (FSP 109-2).” The American Jobs Creation Act of 2004, (the 
“Act”) provides for a special one-time deduction of 85 percent of 
certain foreign earnings repatriated into the U.S. from non-U.S. 
subsidiaries through September 30, 2006. During fiscal 2006, the 
Company repatriated $39.5 million of foreign earnings which qualify 
for the special one-time deduction. Tax expense of $2.4 million was 
recorded in fiscal 2006 as a result of this repatriation. 

In June 2006, the FASB issued FASB Interpretation No. 48, 
“Accounting for Uncertainty in Income Taxes, an Interpretation 
of FASB Statement No. 109.” This Interpretation is effective for 
ESCO beginning October 1, 2007. This Interpretation prescribes a 
recognition threshold and measurement process for the financial 
statement recognition and measurement of a tax position taken 
or expected to be taken in a tax return. The Company is currently 
evaluating the adoption of this Interpretation and does not 
currently have an estimate of the impact on the consolidated 
financial statements.

In September 2006, the FASB issued SFAS No. 158, “Employer’s 
Accounting for Defined Benefit Pension and Other Postretirement 
Plans” (SFAS 158), which amends SFAS 87 and SFAS 106 to require 
recognition of the overfunded or underfunded status of pension 
and other postretirement benefit plans on the balance sheet. Under 
SFAS 158, gains and losses, prior service costs and credits, and any 
remaining transition amounts under SFAS 87 and SFAS 106 that 
have not yet been recognized through net periodic benefit cost will 
be recognized in accumulated other comprehensive income, net of 
tax effects. The measurement date — the date at which the benefit 
obligation and plan assets are measured — is required to be the 
Company’s fiscal year-end, which is the date the Company currently 
uses. SFAS 158 is effective for publicly held companies for fiscal 
years ending after December 15, 2006. The adoption of SFAS 158 is 
not expected to have a material impact to the Company’s financial 
position or results of operations.

Management’s Discussion and Analysis

In September 2006, the SEC issued Staff Accounting Bulletin  
No. 108, “Considering the Effects of Prior Year Misstatements when 
Quantifying Misstatements in Current Year Financial Statements” 
(SAB No. 108), which addresses the diversity in practice in 
quantifying financial statement misstatements and provides 
interpretative guidance regarding the consideration given to prior 
year misstatements when determining materiality in current year 
financial statements. During 2006, the Company adopted the 
provisions of SAB No. 108 and recorded $2.4 million as a cumulative 
credit adjustment to 2006 beginning retained earnings.

In September 2006, the FASB issued SFAS No. 157, “Fair Value 
Measurements” (SFAS 157), which defines fair value in generally 
accepted accounting principles and expands disclosures about 
fair value measurements. This Statement is effective for financial 
statements issued for fiscal years beginning after November 15, 
2007. The adoption of SFAS 157 is not expected to have a material 
impact to the Company’s financial position or results of operations.

in laws and regulations including but not limited to changes in 
accounting standards and taxation requirements; costs relating to 
environmental matters; litigation uncertainty; and the Company’s 
successful execution of internal operating plans.

notes to Consolidated Financial Statements

1. Summary of Significant Accounting policies

A. pRinCiplES OF COnSOliDATiOn 

The consolidated financial statements include the accounts of ESCO 
Technologies Inc. (ESCO) and its wholly owned subsidiaries (the 
Company). All significant intercompany transactions and accounts 
have been eliminated in consolidation. Certain prior year amounts 
have been reclassified to conform with the 2006 presentation. 

B. BASiS OF pRESEnTATiOn

Fair values of the Company’s financial instruments are estimated 
by reference to quoted prices from market sources and financial 
institutions, as well as other valuation techniques. The estimated 
fair value of each class of financial instruments approximated the 
related carrying value at September 30, 2006 and 2005.

C. nATuRE OF OpERATiOnS

The Company has three industry operating units: Communications, 
Filtration/Fluid Flow and Test. The Communications unit is a proven 
supplier of special purpose communications systems for electric, 
gas and water utilities, including hardware and software to support 
advanced metering applications. The Filtration/Fluid Flow unit 
develops, manufactures and markets a broad range of filtration 
products used in the purification and processing of liquids and 
gases. The Test unit is an industry leader in providing its customers 
with the ability to identify, measure and contain magnetic, 
electromagnetic and acoustic energy.

D. uSE OF ESTiMATES 

The preparation of financial statements in conformity with 
accounting principles generally accepted in the United States 
of America (GAAP) requires Management to make estimates and 
assumptions, including estimates of anticipated contract costs and 
revenues utilized in the earnings process, that affect the reported 
amounts of assets and liabilities and disclosure of contingent 
assets and liabilities at the date of the financial statements and the 
reported amounts of revenues and expenses during the reporting 
period. Actual results could differ from those estimates.

E. REVEnuE RECOgniTiOn

Communications Unit: Within the Communications unit, 
approximately 95% of the unit’s revenue arrangements 
(approximately 30% of consolidated revenues) contain software 
components. Revenue under these arrangements is recognized in 
accordance with Statement of Position 97-2 (SOP 97-2), “Software 
Revenue Recognition,” as amended by SOP 98-9, “Modification 
of SOP 97-2, Software Revenue Recognition, with Respect to 
Certain Transactions.” The unit’s software revenue arrangements 
generally include multiple products and services, or “elements” 
consisting of meter and substation hardware, meter reading system 
software, program management support during the deployment 
period and software support (post-contract customer support, 
“PCS”). These arrangements typically require the Company to 
deliver software at the inception of the arrangement while the 

30

E S C O   T E C h n O l O g i E S   i n C .   2 0 0 6   A n n u A l   R E p O R T

hardware, and program management support are delivered over 
the contractual deployment period. Software support is provided 
during deployment and subsequent thereto. The software element 
included in such arrangements is essential to the functionality 
of the hardware and, therefore, the hardware is considered to be 
software-related. Hardware is considered a specified element in the 
software arrangement and vendor-specific objective evidence of 
fair value (“VSOE”) has been established for this element. VSOE for 
the hardware element is determined based on the price when sold 
separately to customers. These revenue arrangements are divided 
into separate units of accounting if the delivered item(s) has 
value to the customer on a stand-alone basis, there is objective 
and reliable evidence of the fair value of the undelivered item(s) 
and delivery/performance of the undelivered item(s) is probable. 
For multiple element arrangements, revenue is allocated to the 
individual elements based on VSOE of the individual elements. 

The application of these principles requires judgment, including 
the determination of whether a software arrangement includes 
multiple elements and estimates of the fair value of the elements. 
The VSOE of the undelivered elements is determined based on 
the historical evidence of stand-alone sales of these elements to 
customers. Hardware revenues are generally recognized at the time 
of shipment or receipt by customer depending upon contract terms. 
VSOE generally does not exist for the software element, therefore, 
the Company uses the residual method to recognize revenue when 
VSOE exists for all other undelivered elements. Under the residual 
method, the fair value of the undelivered elements is deferred  
and the remaining portion of the arrangement fee is recognized  
as revenue. 

SOP 97-2 requires the seller of software that includes post-contract 
customer support (PCS) to establish VSOE of the undelivered 
element of the contract in order to account separately for the PCS 
revenue. The Company determines VSOE by a consistent pricing of 
PCS and PCS renewals as a percentage of the software license fees 
or by reference to contractual renewals, when the renewal terms  
are substantive. Revenues for PCS are recognized ratably over  
the maintenance term specified in the contract (generally in  
12 monthly increments). Revenues for program management support 
are recognized when services have been provided. The Company 
determines VSOE for program management support based on hourly 
rates when services are performed separately.

In November 2005, DCSI and Hexagram entered into arrangements 
with a large utility company to provide software, program 
management services, training and PCS that includes an option 
for the customer to purchase a significant quantity of hardware 
over an initial deployment period of approximately five years and 
subsequently over the remaining initial contract term of up to 
fifteen years. The software, program management services and 
training will be delivered over the initial hardware deployment 
period of approximately five years. PCS will be provided at no 
charge during the first year of the initial deployment period, 
after which it will be provided over subsequent annual periods 
throughout the contract term if the customer chooses to continue 

notes to Consolidated Financial Statements

PCS. Because the program management services are based on a 
fixed price per month rather than on a time and materials basis, the 
Company is unable to establish VSOE for the program management 
services in this arrangement. The Company is able to establish VSOE 
for the PCS based on contractual renewal rates that are consistent 
with other arrangements and for the training based on pricing 
when sold separately. For the DCSI arrangement, the pricing for 
the optional hardware includes a discount that the Company has 
determined to be more-than-insignificant. In accordance with 
applicable software revenue recognition guidance, the Company will 
defer all revenue related to the DCSI arrangement until all software 
is delivered and acceptance criteria have been met. At that time, 
revenue otherwise allocable to the software, program management 
services, training and initial bundled PCS will be reduced by the 
rate of the significant incremental discount offered on the hardware 
products. The portion of the arrangement consideration allocated to 
the significant incremental discount will be recognized ratably over 
the discount period (up to twenty years) similar to a subscription. 
The remaining arrangement consideration will be recognized 
ratably over the period the program management services will be 
performed (the initial deployment period of approximately five 
years). Additional annual fees are payable in each subsequent year 
that PCS is provided and will be recognized over the respective PCS 
period. The amount paid by the customer for optional purchases of 
hardware during the deployment period related to both the DCSI 
and Hexagram arrangements will be recognized upon delivery and 
acceptance, if applicable, assuming all other revenue recognition 
criteria have been met. 

Approximately 5% of unit revenues are recognized when products 
are delivered (when title and risk of ownership transfers) or when 
services are performed for unaffiliated customers. Products include 
the SecurVision® digital video surveillance systems.

Filtration/Fluid Flow Unit: Within the Filtration/Fluid Flow 
operating unit, approximately 75% of operating unit revenues 
(approximately 30% of consolidated revenues) are recognized when 
products are delivered (when title and risk of ownership transfers) 
or when services are performed for unaffiliated customers. 

Approximately 25% of operating unit revenues (approximately 10% 
of consolidated revenues) are recorded under the percentage-of-
completion provisions of SOP 81-1, “Accounting for Performance of 
Construction-Type and Certain Production-Type Contracts.” Products 
accounted for under SOP 81-1 include the design, development 
and manufacture of complex fluid control products, quiet valves, 
manifolds and systems primarily for the aerospace and military 
markets. For arrangements that are accounted for under SOP 81-1, 
the Company estimates profit as the difference between total 
estimated revenue and total estimated cost of a contract and 
recognizes these revenues and costs based on units delivered.  
The percentage-of-completion method of accounting involves the 
use of various techniques to estimate expected costs at completion. 

Test Unit: Within the Test unit, approximately 60% of revenues 
(approximately 20% of consolidated revenues) are recognized when 
products are delivered (when title and risk of ownership transfers) 

or when services are performed for unaffiliated customers. Certain 
arrangements contain multiple elements which are accounted for 
under the provisions of EITF 00-21, “Revenue Arrangements with 
Multiple Deliverables.” The multiple elements generally consist 
of materials and installation services used in the construction 
and installation of standard shielded enclosures to measure and 
contain magnetic and electromagnetic energy. The installation 
process does not involve changes to the features or capabilities of 
the equipment and does not require proprietary information about 
the equipment in order for the installed equipment to perform to 
specifications. There is objective and reliable evidence of fair value 
for each of the units of accounting, as a result, the arrangement 
revenue is allocated to the separate units of accounting based on 
their relative fair values. Typically, fair value is the price of the 
deliverable when it is regularly sold on a stand-alone basis. 

Approximately 40% of the unit’s revenues (approximately 10% 
of consolidated revenues) are recorded under the percentage-of-
completion provisions of SOP 81-1, “Accounting for the Performance 
of Construction-Type and Certain Production-Type Contracts” due 
to the complex nature of the enclosures that are designed and 
produced under these contracts. Products accounted for under SOP 
81-1 include the construction and installation of complex test 
chambers to a buyer’s specifications that provide its customers 
with the ability to measure and contain magnetic, electromagnetic 
and acoustic energy. As discussed above, for arrangements that are 
accounted for under SOP 81-1, the Company estimates profit as the 
difference between total estimated revenue and total estimated 
cost of a contract and recognizes these revenues and costs based 
on either (a) units delivered or (b) contract milestones. 

If a reliable measure of output cannot be established (which 
applies in less than 8% of Test unit revenues or 2% of consolidated 
revenues), input measures (e.g., costs incurred) are used to 
recognize revenue. Given the nature of the Company’s operations 
related to these contracts, costs incurred represent an appropriate 
measure of progress towards completion. 

The percentage-of-completion method of accounting involves the 
use of various techniques to estimate expected costs at completion. 
These estimates are based on Management’s judgment and the 
Company’s substantial experience in developing these types  
of estimates. 

F. CASh AnD CASh EQuiVAlEnTS 

Cash equivalents include temporary investments that are readily 
convertible into cash, such as Eurodollars, commercial paper and 
treasury bills with original maturities of three months or less.

g. ACCOunTS RECEiVABlE

Accounts receivable have been reduced by an allowance for  
amounts that the Company estimates are uncollectible in the  
future. This estimated allowance is based on Management’s 
evaluation of the financial condition of the customer and  
historical write-off experience.

h. COSTS AnD ESTiMATED EARningS On lOng-TERM COnTRACTS

Costs and estimated earnings on long-term contracts represent  
unbilled revenues, including accrued profits, accounted for under 
the percentage-of-completion method, net of progress billings.

i. inVEnTORiES

Inventories are valued at the lower of cost (first-in, first-out)  
or market value. Inventories under long-term contracts reflect  
accumulated production costs, factory overhead, initial tooling and 
other related costs less the portion of such costs charged to cost of 
sales and any unliquidated progress payments. In accordance with 
industry practice, costs incurred on contracts in progress include 
amounts relating to programs having production cycles longer than 
one year, and a portion thereof will not be realized within one year.

J. pROpERTY, plAnT AnD EQuipMEnT

Property, plant and equipment are recorded at cost. Depreciation 
and amortization are computed primarily on a straight-line basis 
over the estimated useful lives of the assets: buildings, 10-40 
years; machinery and equipment, 5-10 years; and office furniture 
and equipment, 5-10 years. Leasehold improvements are amortized 
over the remaining term of the applicable lease or their estimated 
useful lives, whichever is shorter.

K. gOODWill AnD OThER lOng-liVED ASSETS

Goodwill represents the excess of purchase costs over the fair 
value of net identifiable assets acquired in business acquisitions. 
The Company accounts for goodwill as required by Statement of 
Financial Accounting Standards (SFAS) 142, “Goodwill and Other 
Intangible Assets.” Management annually reviews goodwill and 
other long-lived assets with indefinite useful lives for impairment 
or whenever events or changes in circumstances indicate the  
carrying amount may not be recoverable. If the Company deter-
mines that the carrying value of the long-lived asset may not be 
recoverable, a permanent impairment charge is recorded for the 
amount by which the carrying value of the long-lived asset exceeds 
its fair value. Fair value is measured based on a discounted cash 
flow method using a discount rate determined by Management to 
be commensurate with the risk inherent in the Company’s current 
business model. Other intangible assets represent costs allocated 
to identifiable intangible assets, principally capitalized software, 
patents, trademarks, and technology rights. See Note 5 regarding 
goodwill and other intangible assets activity.

l. CApiTAliZED SOFTWARE

The costs incurred for the development of computer software that 
will be sold, leased, or otherwise marketed are charged to expense 
when incurred as research and development until technological 
feasibility has been established for the product. Technological 
feasibility is typically established upon completion of a detailed 
program design. Costs incurred after this point are capitalized 
on a project-by-project basis in accordance with SFAS No. 86, 
“Accounting for the Costs of Computer Software to be Sold, Leased 

32

E S C O   T E C h n O l O g i E S   i n C .   2 0 0 6   A n n u A l   R E p O R T

or Otherwise Marketed.” Costs that are capitalized primarily consist 
of external development costs. Upon general release of the product 
to customers, the Company ceases capitalization and begins 
amortization, which is calculated on a project-by-project basis as 
the greater of (1) the ratio of current gross revenues for a product 
to the total of current and anticipated future gross revenues for 
the product or (2) the straight-line method over the estimated 
economic life of the product. The Company generally amortizes 
the software development costs over a three to seven year period 
based upon the estimated future economic life of the product. 
Factors considered in determining the estimated future economic 
life of the product include anticipated future revenues, and changes 
in software and hardware technologies. The carrying values of 
capitalized costs are evaluated for impairment on an annual basis 
to determine if circumstances exist which indicate the carrying 
value of the asset may not be recoverable. If expected cash flows 
are insufficient to recover the carrying amount of the asset, then  
an impairment loss is recognized to state the asset at its net 
realizable value. 

M.  iMpAiRMEnT OF lOng-liVED ASSETS AnD lOng-liVED ASSETS  

TO BE DiSpOSED OF 

Recoverability of assets to be held and used is measured by a 
comparison of the carrying amount of an asset to future cash flows 
expected to be generated by the asset. If such assets are considered 
to be impaired, the impairment to be recognized is measured by 
the amount by which the carrying amount of the assets exceeds the 
fair value of the assets. Assets to be disposed of are reported at the 
lower of the carrying amount or fair value less costs to dispose.

n. inCOME TAXES

Income taxes are accounted for under the asset and liability 
method. Deferred tax assets and liabilities are recognized for 
the future tax consequences attributable to differences between 
the financial statement carrying amounts of existing assets and 
liabilities and their respective tax bases. Deferred tax assets and 
liabilities are measured using enacted tax rates expected to apply 
to taxable income in the years in which those temporary differences 
are expected to be recovered or settled. Deferred tax assets may be 
reduced by a valuation allowance if it is more likely than not that 
some portion or all of the deferred tax assets will not be realized. 
The effect on deferred tax assets and liabilities of a change in 
tax rates is recognized in income in the period that includes the 
enactment date. The Company regularly reviews its deferred tax 
assets for recoverability and establishes a valuation allowance when 
Management believes it is more likely than not such assets will not 
be recovered, taking into consideration historical operating results, 
expectations of future earnings, tax planning strategies, and the 
expected timing of the reversals of existing temporary differences.

O. RESEARCh AnD DEVElOpMEnT COSTS

Company-sponsored research and development costs include 
research and development and bid and proposal efforts related 
to the Company’s products and services. Company-sponsored 

notes to Consolidated Financial Statements

product development costs are charged to expense when incurred. 
Customer-sponsored research and development costs incurred 
pursuant to contracts are accounted for similar to other program 
costs. Customer-sponsored research and development costs refer 
to certain situations whereby customers provide funding to 
support specific contractually defined research and development 
costs. As the Company incurs costs under these specific funding 
contracts, the costs are “inventoried” until billed to the customer 
for reimbursement, consistent with other program costs. Once 
billed/invoiced, these costs are transferred to accounts receivable 
until the cash is received from the customer. All research and 
development costs incurred in excess of the contractual funding 
amount, or costs incurred outside the scope of the contractual 
research and development project, are expensed as incurred.

p. FOREign CuRREnCY TRAnSlATiOn

The financial statements of the Company’s foreign operations 
are translated into U.S. dollars in accordance with SFAS 52 
“Foreign Currency Translation” (SFAS 52). The resulting translation 
adjustments are recorded as a separate component of accumulated 
other comprehensive income.

Q. EARningS pER ShARE

Basic earnings per share is calculated using the weighted average 
number of common shares outstanding during the period. Diluted 
earnings per share is calculated using the weighted average number 
of common shares outstanding during the period plus shares 
issuable upon the assumed exercise of dilutive common share 
options and vesting of performance-accelerated restricted shares 
using the treasury stock method. On August 5, 2005, the Company’s 
Board of Directors approved a 2-for-1 stock split which was effected 
as a 100 percent stock dividend and was paid on September 23, 
2005 to shareholders of record as of September 9, 2005. The 2004 
common stock and per share amounts have been adjusted to reflect 
the stock split.

The number of shares used in the calculation of earnings per share 
for each year presented is as follows:

(In thousands)

Options to purchase 264,430 shares at prices ranging from  
$42.99 - $54.88 were outstanding during the year ended  
September 30, 2006, but were not included in the respective 
computation of diluted EPS because the options’ exercise price  
was greater than the average market price of the common shares. 
Options to purchase 34,967 shares at prices ranging from $35.18 - 
$50.26 were outstanding during the year ended September 30, 
2005, but were not included in the respective computation of 

diluted EPS because the options’ exercise price was greater than  
the average market price of the common shares. Options to 
purchase 212,228 shares at prices ranging from $22.68 - $32.33 
were outstanding during the year ended September 30, 2004, but 
were not included in the respective computation of diluted EPS 
because the options’ exercise price was greater than the average 
market price of the common shares. These options expire in various 
periods through 2013. Approximately 9,000, 36,000 and 14,000 
restricted shares were outstanding but unearned at September 30, 
2006, 2005 and 2004, respectively, and, therefore, were not 
included in the respective years’ computations of diluted EPS.

R. ShARE-BASED COMpEnSATiOn

Prior to October 1, 2005, the Company accounted for its stock 
option plans using the intrinsic value method of accounting 
provided under APB Opinion No. 25, “Accounting for Stock 
Issued to Employees,” (APB 25) and related interpretations, as 
permitted by FASB Statement No. 123, “Accounting for Stock-Based 
Compensation,” (SFAS 123) under which no compensation expense 
was recognized for stock option grants. Accordingly, share-based 
compensation for stock options was included as a pro forma 
disclosure in the financial statement footnotes for periods prior  
to fiscal 2006.

Effective October 1, 2005, the Company adopted the fair value 
recognition provisions of FASB Statement No. 123(R), “Share-Based 
Payment,” (SFAS 123(R)) using the modified-prospective transition 
method. Under this transition method, compensation cost recog-
nized in fiscal 2006 includes: 

a)  compensation cost for all share-based payments granted through 
September 30, 2005, for which the requisite service period had 
not been completed as of September 30, 2005, based on the 
grant date fair value estimated in accordance with the original 
provisions of SFAS 123, and 

b)  compensation cost for all share-based payments granted  

subsequent to September 30, 2005, based on the grant date 
fair value estimated in accordance with the provisions of SFAS 
123(R). Results for prior periods have not been restated.

As a result of adopting SFAS 123(R) on October 1, 2005, the 
Company’s net earnings for the year ended September 30, 2006 
were $2.3 million lower than if it had continued to account for 
share-based compensation under APB 25. 

The Company has various share-based plans which allow the 
Company to grant key officers, managers and professional employees 
(1) options to purchase shares of the Company’s common stock, 
(2) stock appreciation rights with respect to all or any part of 
the number of shares covered by the options, or (3) performance-
accelerated restricted shares (restricted shares) and other full  
value awards. No stock appreciation rights have been awarded to 
date. In addition, the Company provides compensation benefits 
to non-employee directors under a non-employee directors 
compensation plan.

notes to Consolidated Financial Statements

S. COMpREhEnSiVE inCOME (lOSS)

SFAS 130, “Reporting Comprehensive Income” requires the Company 
to report separately the translation adjustments of SFAS 52 
defined above, and changes to the minimum pension liability, as 
components of comprehensive income or loss. Management has 
chosen to disclose the requirements of this Statement within the 
Consolidated Statements of Shareholders’ Equity.

Accumulated other comprehensive loss as shown on the 
consolidated balance sheet of $(2.1) million and $(5.6) million 
at September 30, 2006 and 2005, respectively, consisted of 
$4.5 million and $3.0 million related to currency translation 
adjustments; $(6.6) million and $(8.6) million related to the 
minimum pension liability, respectively.

T. DEFERRED REVEnuE

Deferred revenue is recorded for products or services that have 
not been provided but have been invoiced under contractual 
agreements or paid for by a customer, or when products or services 
have been provided but the criteria for revenue recognition have 
not been met. If there is a customer acceptance provision or there 
is uncertainty about customer acceptance, revenue is deferred 
until the customer has accepted the product or service. The current 
portion of approximately $3.0 million is classified in accrued 
expenses on the Consolidated Balance Sheet.

Deferred revenue also includes the long-term portion of unearned 
income related to two intellectual property agreements. The 
amount is being amortized into income on a straight-line basis 
over the remaining patent life through 2011. The current portion of 
approximately $0.6 million is classified in accrued expenses on the 
Consolidated Balance Sheet.

u. nEW ACCOunTing STAnDARDS

In December 2004, the FASB issued SFAS No. 123(R), “Share-Based 
Payment” (SFAS 123(R)). This Statement replaces SFAS No. 123, 
“Accounting for Stock-Based Compensation” and supersedes APB 
No. 25, “Accounting for Stock Issued to Employees.” SFAS 123(R) 
requires all stock-based compensation to be recognized as an 
expense in the financial statements and that such cost be measured 
according to the fair value of stock options. The Company adopted 
the provisions of this Statement in the first quarter of fiscal 2006 
on a prospective basis. 

In December 2004, the FASB issued FASB Staff Position FAS 109-2, 
“Accounting and Disclosure Guidance for the Foreign Earnings 
Repatriation Provision within the American Jobs Creation Act of 
2004” (FSP 109-2). The American Jobs Creation Act of 2004, (the 
“Act”) provides for a special one-time deduction of 85 percent of 
certain foreign earnings repatriated into the U.S. from non-U.S. 
subsidiaries through September 30, 2006. During fiscal 2006, the 
Company repatriated $39.5 million of foreign earnings which qualify 
for the special one-time deduction. Tax expense of $2.4 million was 
recorded in fiscal 2006 as a result of this repatriation.

E S C O   T E C h n O l O g i E S   i n C .   2 0 0 6   A n n u A l   R E p O R T

In June 2006, the FASB issued FASB Interpretation No. 48, 
“Accounting for Uncertainty in Income Taxes, an Interpretation 
of FASB Statement No. 109.” This Interpretation is effective for 
ESCO beginning October 1, 2007. This Interpretation prescribes a 
recognition threshold and measurement process for the financial 
statement recognition and measurement of a tax position taken 
or expected to be taken in a tax return. The Company is currently 
evaluating the adoption of this Interpretation and does not 
currently have an estimate of the impact on the consolidated 
financial statements.

In September 2006, the FASB issued SFAS No. 158, “Employer’s 
Accounting for Defined Benefit Pension and Other Postretirement 
Plans” (SFAS 158), which amends SFAS 87 and SFAS 106 to require 
recognition of the overfunded or underfunded status of pension 
and other postretirement benefit plans on the balance sheet. Under 
SFAS 158, gains and losses, prior service costs and credits, and any 
remaining transition amounts under SFAS 87 and SFAS 106 that 
have not yet been recognized through net periodic benefit cost will 
be recognized in accumulated other comprehensive income, net of 
tax effects. The measurement date — the date at which the benefit 
obligation and plan assets are measured — is required to be the 
Company’s fiscal year-end, which is the date the Company currently 
uses. SFAS 158 is effective for publicly-held companies for fiscal 
years ending after December 15, 2006. The adoption of SFAS 158 is 
not expected to have a material impact to the Company’s financial 
position or results of operations. 

In September 2006, the SEC issued Staff Accounting Bulletin  
No. 108, “Considering the Effects of Prior Year Misstatements when 
Quantifying Misstatements in Current Year Financial Statements” 
(SAB No. 108), which addresses the diversity in practice in 
quantifying financial statement misstatements and provides 
interpretative guidance regarding the consideration given to prior 
year misstatements when determining materiality in current year 
financial statements. During 2006, the Company adopted the 
provisions of SAB No. 108 and recorded $2.4 million as a cumulative 
credit adjustment to 2006 beginning retained earnings.

In September 2006, the FASB issued SFAS No. 157, “Fair Value 
Measurements” (SFAS 157), which defines fair value in generally 
accepted accounting principles and expands disclosures about 
fair value measurements. This Statement is effective for financial 
statements issued for fiscal years beginning after November 15, 
2007. The adoption of SFAS 157 is not expected to have a material 
impact to the Company’s financial position or results of operations.

2. Acquisitions

Effective February 1, 2006, the Company acquired the capital stock 
of Hexagram, Inc. (Hexagram) for a purchase price of approximately 
$66 million. The acquisition agreement also provides for contin-
gent consideration of up to $6.25 million over the five year period 
following the acquisition if Hexagram exceeds certain sales targets. 
Hexagram is an RF fixed network automatic meter reading (AMR) 
company headquartered in Cleveland, Ohio. Hexagram broadens 
the Company’s served market and provides an RF based AMI system 

notes to Consolidated Financial Statements

serving primarily gas and water utilities. Hexagram’s annual revenue 
over the past three years has been in the range of $20 million to 
$35 million. The operating results for Hexagram, since the date of 
acquisition, are included within the Communications unit. The Com-
pany recorded $6.6 million of amortizable identifiable intangible 
assets consisting primarily of patents and proprietary know-how, 
customer contracts, and order backlog which are being amortized 
on a straight-line basis over periods ranging from six months to 
seven years. 

The following table summarizes the Company’s estimates of the fair 
values of the assets acquired and liabilities assumed at the date of 
acquisition and includes subsequent adjustments to the allocation 
of purchase price.

Effective November 29, 2005, the Company acquired Nexus Energy 
Software, Inc. (Nexus) through an all cash for shares merger 
transaction for approximately $29 million in cash plus contingent 
cash consideration over the four year period following the merger 
if Nexus exceeds certain sales targets. Nexus is a software company 
headquartered in Wellesley, Massachusetts with annual revenues in 
the past in excess of $10 million. Nexus broadens the Company’s 
served market and provides software solutions that allow utilities 
to fully utilize the information produced by the Company’s AMI 
systems. The operating results for Nexus, since the date of acquisi-
tion, are included within the Communications unit. The Company 
recorded $2.7 million of identifiable intangible assets consisting 
primarily of customer contracts and order backlog which are being 
amortized on a straight-line basis over periods ranging from one 
year to three years. In connection with the acquisition of Nexus, 
the Company acquired approximately $13 million of net operating 

loss carryforward that will expire between 2017 and 2025 and is 
subject to a Section 382 limitation.

The following table summarizes the Company’s estimates of the fair 
values of the assets acquired and liabilities assumed at the date of

All of the Company’s acquisitions have been accounted for using 
the purchase method of accounting and accordingly, the respective 
purchase prices were allocated to the assets (including intangible 
assets) acquired and liabilities assumed based on estimated 
fair values at the date of acquisition. The financial results from 
these acquisitions have been included in the Company’s financial 
statements from the date of acquisition. Pro forma financial 
information related to the Nexus and Hexagram acquisitions was 
not presented as it was not significant to the Company’s results of 
operations. None of the goodwill recorded as part of the Nexus or 
Hexagram acquisitions is expected to be deductible for U.S. federal 
or state income tax purposes.

3. Discontinued Operations

The MicroSep businesses consisted of PTI Advanced Filtration 
Inc., PTI Technologies Limited, and PTI S.p.A. Effective April 2, 
2004, the Company completed the sale of PTI Advanced Filtration 
Inc. (Oxnard, California) and PTI Technologies Limited (Sheffield, 
England) to domnick hunter group plc for $18 million in cash. On 
June 8, 2004, the Company completed the sale of PTI S.p.A. (Milan, 
Italy) to a group of investors comprised of the subsidiary’s senior 
management for $5.3 million. An after-tax gain of $1.6 million 
related to the sale of the MicroSep businesses is reflected in the 
Company’s 2004 results in discontinued operations.

The MicroSep businesses are accounted for as a discontinued 
operation in accordance with SFAS 144, “Accounting for the 
Impairment or Disposal of Long-Lived Assets” (SFAS 144) and, 
accordingly, amounts in the financial statements and related notes 
for all periods shown, reflect discontinued operations presentation. 
The net sales from the MicroSep businesses were $29.4 million 
for the year ended September 30, 2004. The pre-tax loss from 
operations from the MicroSep businesses was $5.0 million for  
the year ended September 30, 2004.

The Company performed its annual evaluation of goodwill for im-
pairment during the fourth quarter of fiscal 2006 and concluded no 
impairment existed at September 30, 2006.

The changes in the carrying amount of goodwill attributable to each 
business segment for the years ended September 30, 2006 and 2005 
are as follows:

4. Asset impairment

In June 2005, the Company abandoned its plans to commercialize 
certain sensor products within the Filtration/Fluid Flow segment. 
This action resulted in an asset impairment charge of $0.8 million 
to write off certain patents and a related licensing agreement 
to their respective fair market values. The Company ended its 
development efforts on this program after it determined that 
the market was not developing as quickly as anticipated and the 
expected costs and time frame to fully commercialize the products 
were not acceptable.

Amortization expense related to intangible assets with determinable 
lives was $6.9 million, $2.0 million and $2.1 million in 2006, 
2005 and 2004, respectively. The increase in amortization expense 
in 2006 as compared to the prior year was due to $2.7 million of 
amortization related to the Nexus and Hexagram acquired intangible 
assets and $2.2 million of amortization related to the Company’s 
TNG software. Patents are amortized over the life of the patents, 
generally 17 years. Capitalized software is amortized over the 
estimated useful life of the software, generally 3-7 years. Estimated 
intangible assets amortization for fiscal year 2007 is approximately 
$11 million. Estimated intangible asset amortization for fiscal years 
2008 through 2011 is estimated at approximately $12 million to 
$13 million per year. The increase in intangible asset amortization 
is related to the additional costs associated with the TNG software.

Management believes that, based on the Company’s historical pretax 
income together with the projection of future taxable income, and 
after consideration of the valuation allowance, it is more likely than 
not that the Company will realize the benefits of the net deferred 
tax assets existing at September 30, 2006. In order to realize this 
net deferred tax asset, the Company will need to generate future 
taxable income of approximately $59 million, of which $15 million 
is required to be realized prior to the expiration of the NOL carry-
forward in the United States. The expiration of the NOL carryforward 
is between 2019 and 2025. The Company anticipates being able to 
utilize the NOL carryforward to reduce future Federal income tax 
cash payments.

The Company has established a valuation allowance of $7.4 million 
against the capital loss carryforward generated in 2004, as such 
loss carryforward may not be realized in future periods. In addition, 
the Company has established a valuation allowance against certain 
NOL carryforwards in foreign jurisdictions which may not be realized 
in future periods. The valuation allowance established against the 
foreign NOL carryforwards was $2.9 million and $1.7 million at 
September 30, 2006 and 2005, respectively. The Company classifies 
its valuation allowance related to deferred taxes on a pro rata basis. 
The Company reclassified the current and long-term portion of its 
valuation allowance as of September 30, 2005 to be consistent with 
the current year presentation.

On October 22, 2004, the President of the United States signed into 
law the American Jobs Creation Act of 2004 (the “2004 Jobs Act”). 
The 2004 Jobs Act repeals the extraterritorial income exclusion and 
provides for (i) a new deduction for domestic manufacturing and 
production income, (ii) international tax reforms, (iii) a temporary 
incentive for U.S. multinational companies to reinvest foreign 
earnings in the U.S., and (iv) numerous other business tax relief 
provisions. The foreign earnings repatriation provision provides an 
85% dividends received deduction for certain dividends received 
from controlled foreign corporations. In addition, in December 
2004, the FASB issued FASB Staff Position FAS 109-2, “Accounting 
and Disclosure Guidance for the Foreign Earnings Repatriation Provi-
sion within the American Jobs Creation Act of 2004” (2004 Jobs 
Act). The Company repatriated $39.5 million of funds to reinvest 
in the U.S. under the 2004 Jobs Act. Federal income taxes on the 
repatriated amounts were based on the 5.25% effective statutory 
rate as provided in the 2004 Jobs Act, plus applicable state income 
and foreign withholding taxes. Federal income taxes and applicable 
withholding taxes of $2.4 million have been provided for in the 
current year provision.

Under current law, the research credit expired for research 
expenditures incurred after December 31, 2005. The Company began 
an analysis of available research credits for the period beginning in 
2000 and ending with the three month period ended December 31, 
2005. The Company expects that these research credit claims will  
be approximately $2.5 million.

No deferred taxes have been provided on the accumulated 
unremitted earnings of the Company’s foreign subsidiaries as of 
September 30, 2006. The Company’s intention is to reinvest these 
earnings indefinitely. In the event these foreign entities’ earnings 
were distributed, it is estimated that U.S. taxes, net of available 
foreign tax credits, of approximately $3.2 million would be due, 
which would correspondingly reduce the Company’s net earnings.

During 2006, the Company determined that state tax expense had 
not been accurately recorded in the financial statements for years 
2001 through 2005. The effect in any individual prior year was not 
material to the Company’s results of operations, financial position 
or cash flows. The Company adopted the provisions of SEC Staff 
Accounting Bulletin No. 108, “Considering the Effects of Prior Year 
Misstatements when Quantifying Misstatements in Current Year 
Financial Statements” and recorded $2.4 million as a cumulative 
credit adjustment to 2006 beginning retained earnings. 

The Company operates within multiple taxing jurisdictions and is 
subject to audit in these jurisdictions. These audits can involve 
complex issues which may require an extended period of time to 
resolve. The Company regularly reviews its potential tax liabilities 
for tax years subject to audit. Changes in the Company’s potential 
tax liability occurred during the year ended September 30, 2006, 
and may occur in the future as the Company’s assessment changes 
based on examinations in various jurisdictions and/or changes in 
tax laws, regulations and case law. Accordingly, the Company’s 
estimate of income tax liabilities may differ from actual payments 
or assessments.

10. Debt

At September 30, 2006 and 2005, there were no outstanding 
borrowings under the revolving credit facility. Effective October 6, 
2004, the Company entered into a $100 million five-year revolving 
bank credit facility with a $50 million increase option that has a 
final maturity and expiration date of October 6, 2009. The credit 
facility is available for direct borrowings and/or the issuance of 
letters of credit, and is provided by a group of six banks, led by 
Wells Fargo Bank as agent. At September 30, 2006, the Company 
had approximately $99.2 million available to borrow under the 
credit facility in addition to $36.8 million cash on hand. At 
September 30, 2006, the Company had outstanding letters of credit 
of $1.5 million ($0.8 million outstanding under the credit facility). 
On February 1, 2006, the Company borrowed $47 million to partially 
fund the acquisition of Hexagram which was subsequently repaid 
from the foreign cash repatriation by March 31, 2006. The interest 

 
 
 
notes to Consolidated Financial Statements

rate on this debt was approximately 5.3%. During April 2006, the 
Company borrowed $5 million which was subsequently repaid prior 
to April 30, 2006. The interest rate on this debt was 7.75%. 

The credit facility requires, as determined by certain financial 
ratios, a commitment fee ranging from 17.5 to 27.5 basis points 
per annum on the unused portion. The terms of the facility provide 
that interest on borrowings may be calculated at a spread over the 
London Interbank Offered Rate (LIBOR) or based on the prime rate, 
at the Company’s election. The facility is secured by the unlimited 
guaranty of the Company’s material domestic subsidiaries and a 65% 
pledge of the material foreign subsidiaries’ share equity. The finan-
cial covenants of the credit facility include limitations on leverage, 
minimum consolidated EBITDA and minimum net worth. 

During 2006 and 2005, the maximum aggregate short-term 
borrowings at any month-end were $47 million and zero,  
respectively; the average aggregate short-term borrowings 
outstanding based on month-end balances were $3.9 million and 
zero, respectively; and the weighted average interest rates were 
5.25%, not applicable in 2005, and 1.87% in 2004. The letters  
of credit issued and outstanding under the credit facility totaled 
$0.8 million and $1.4 million at September 30, 2006, and  
2005, respectively. 

11. Capital Stock

The 29,030,995 and 28,738,958 common shares as presented in the 
accompanying Consolidated Balance Sheets at September 30, 2006 
and 2005 represent the actual number of shares issued at the 
respective dates. The Company held 3,166,026 and 3,175,626 
common shares in treasury at September 30, 2006 and  
2005, respectively. 

In August 2006, the Company’s Board of Directors authorized 
an open market common stock repurchase program for up to 
1.2 million shares, subject to market conditions and other factors 
which covers the period through September 30, 2008. There were 
no stock repurchases during fiscal 2006. The Company repurchased 
670,072 and 312,400 shares in 2005 and 2004, respectively, under 
a previously authorized program. 

Effective October 1, 2005, the Company adopted the fair value 
recognition provisions of FASB Statement No. 123(R), “Share-Based 
Payment,” (SFAS 123(R)) using the modified-prospective transition 
method. Under this transition method, compensation cost recog-
nized in fiscal 2006 includes: 

c)  compensation cost for all share-based payments granted through 
September 30, 2005, for which the requisite service period had 
not been completed as of September 30, 2005, based on the 
grant date fair value estimated in accordance with the original 
provisions of SFAS 123, and 

d)  compensation cost for all share-based payments granted 

subsequent to September 30, 2005, based on the grant date  
fair value estimated in accordance with the provisions of SFAS 
123(R). Results for prior periods have not been restated.

As a result of adopting SFAS 123(R) on October 1, 2005, the 
Company’s net earnings for the year ended September 30, 2006 
were $2.3 million lower than if it had continued to account for 
share-based compensation under APB 25. 

The Company has various share-based plans which allow the 
Company to grant key officers, managers and professional employees 
(1) options to purchase shares of the Company’s common stock, 
(2) stock appreciation rights with respect to all or any part of 
the number of shares covered by the options, or (3) performance-
accelerated restricted shares and other stock based awards. No 
stock appreciation rights have been awarded to date. In addition, 
the Company provides compensation benefits to non-employee 
directors under a non-employee directors compensation plan. 
During fiscal 2004, the Board of Directors authorized and the 
shareholders approved, the 2004 Incentive Compensation Plan, 
which states, in part, that on February 5, 2004, there shall be 
added to the authorized shares allocated 2,000,000 shares for the 
grant of stock options, stock appreciation rights, performance-
accelerated restricted stock, or other full value awards. Of these, 
shares up to 600,000 may be utilized for performance-accelerated 
restricted stock or other full value awards. At September 30, 
2006, the maximum number of full value shares available for issue 
under the 2004 Incentive Compensation Plan and the 2001 Stock 
Incentive Plan was 600,000 and 330,032 shares, respectively. 

12. Share-Based Compensation

Stock Option plans

Prior to October 1, 2005, the Company accounted for its stock 
option plans using the intrinsic value method of accounting 
provided under APB Opinion No. 25, “Accounting for Stock 
Issued to Employees,” (APB 25) and related interpretations, as 
permitted by FASB Statement No. 123, “Accounting for Stock-Based 
Compensation,” (SFAS 123) under which no compensation expense 
was recognized for stock option grants. Accordingly, share-based 
compensation for stock options was included as a pro forma 
disclosure in the financial statement footnotes for periods prior  
to fiscal 2006.

The Company’s stock option awards are generally subject to graded 
vesting over a three year service period. All outstanding options 
were granted at prices equal to fair market value at the date of 
grant. The options granted prior to September 30, 2003 have a 
ten-year contractual life from date of issuance, expiring in various 
periods through 2013. Beginning in fiscal 2004, the options granted 
have a five-year contractual life from date of issuance. Beginning 
with fiscal 2006 awards, the Company recognizes compensation cost 
on a straight-line basis over the requisite service period for the 
entire award. Prior to fiscal 2006, the Company calculated the  
pro forma compensation cost using the graded vesting method  
(FIN 28 approach).

notes to Consolidated Financial Statements

The fair value of each option award is estimated as of the date of 
grant using a Black-Scholes option pricing model. The weighted 
average assumptions for the periods indicated are noted below. 
Expected volatility is based on historical volatility of ESCO’s stock 
calculated over the expected term of the option. The expected 
term was calculated in accordance with Staff Accounting Bulletin 
No. 107 using the simplified method for “plain-vanilla” options. 
The risk-free rate for the expected term of the option is based on 

the U.S. Treasury yield curve in effect at the date of grant. The 
fair value of each option grant is estimated on the date of grant 
using the Black-Scholes option-pricing model with the following 
weighted-average assumptions used for grants in 2006, 2005 and 
2004, respectively: expected dividend yield of 0% in all periods; 
expected volatility of 28.0%, 23.5% and 21.4%; risk-free interest 
rate of 4.6%, 3.9% and 4.2%; and expected term of 3.50 years, 
3.58 years and 4.25 years.

performance-accelerated Restricted Share Awards

The performance-accelerated restricted shares (restricted shares) 
vest over five years with accelerated vesting if certain performance 
targets are achieved. In these cases, if it is probable that the 
performance condition will be met, the Company recognizes 
compensation cost on a straight-line basis over the shorter 
performance period; otherwise, it will recognize compensation 
cost over the longer service period. Compensation cost for all 
outstanding restricted share awards is being recognized over the 
shorter performance period as it is probable the performance 
condition will be met. The restricted share award grants were valued

non-Employee Directors plan

The non-employee directors compensation plan provides to each 
non-employee director a retainer of 800 common shares per quarter. 
Compensation expense related to the non-employee director grants 
was $1.0 million, $0.7 million and $0.4 million for the years ended 
September 30, 2006, 2005 and 2004, respectively.

The total share-based compensation cost that has been recognized 
in results of operations and included within SG&A was $4.8 million, 
$2.6 million and $1.8 million for the years ended September 30, 
2006, 2005 and 2004, respectively. The total income tax benefit 
recognized in results of operations for share-based compensation 
arrangements was $1.2 million, $1.0 million and $0.7 million for 
the years ended September 30, 2006, 2005 and 2004, respectively. 
The Company has elected to use tax law ordering rules when 
calculating the income tax benefit associated with its share-
based payment arrangements. In addition, the Company elected 
to use the simplified method of calculating the pool of excess 
tax benefits available to absorb tax deficiencies recognized 
subsequent to the adoption of SFAS No. 123(R)-3, “Transition 
Election related to Accounting for the Tax Effects of Share-Based 
Payment Awards.” As of September 30, 2006, there was $8.4 million 
of total unrecognized compensation cost related to share-based 
compensation arrangements. That cost is expected to be recognized 
over a weighted-average period of 3.5 years.

13. Retirement and Other Benefit plans

Substantially all employees are covered by defined contribution 
pension plans maintained by the Company for the benefit of its 
employees. Effective December 31, 2003, the Company’s defined 
benefit plan was frozen and no additional benefits will be accrued 
after that date. As a result, the accumulated benefit obligation and 
projected benefit obligation are equal. These frozen retirement 
income benefits are provided to employees under defined benefit 
pay-related and flat-dollar plans, which are noncontributory. The 
annual contributions to retirement plans equal or exceed the 
minimum funding requirements of the Employee Retirement Income 
Security Act or applicable local regulations. In addition to providing 
retirement income benefits, the Company provides unfunded 
postretirement health and life insurance benefits to certain retirees. 
To qualify, an employee must retire at age 55 or later and the 
employee’s age plus service must equal or exceed 75. Retiree 
contributions are defined as a percentage of medical premiums. 
Consequently, retiree contributions increase with increases in the 
medical premiums. The life insurance plans are noncontributory  
and provide coverage of a flat dollar amount for qualifying  
retired employees.

The Company uses a measurement date of September 30 for its 
pension and other postretirement benefit plans. The Company has 
an accrued benefit liability of $1.8 million and $1.9 million at 
September 30, 2006 and 2005, respectively, related to its other 
postretirement benefit obligations. All other information related to 
its postretirement benefit plans is not considered material to the 
Company’s results of operations or financial condition.

pension plans and fair value of assets over the two-year period

The asset allocation for the Company’s pension plans at the end 
of 2006 and 2005, the Company’s acceptable range and the target 
allocation for 2007, by asset category, follows:

The Company’s pension plan assets are managed by outside 
investment managers and assets are rebalanced when the target 
ranges are exceeded. Pension plan assets consist principally 
of marketable securities including common stocks, bonds, and 
interest-bearing deposits. The Company’s investment strategy 
with respect to pension assets is to achieve a total rate of return 
(income and capital appreciation) that is sufficient to accomplish 
the purpose of providing retirement benefits to all eligible and 
future retirees of the pension plans. The Company regularly 
monitors performance and compliance with investment guidelines.

data processing and secure communication. Accounting policies of  
the segments are the same as those described in the summary of 
significant accounting policies in note 1 to the Consolidated

as: Earnings Before Interest and Taxes. Intersegment sales and 
transfers are not significant. Segment assets consist primarily of 
customer receivables, inventories, capitalized software and fixed 
assets directly associated with the production processes of the 
segment. Segment depreciation and amortization is based upon  
the direct assets listed above.

16. Commitments and Contingencies

At September 30, 2006, the Company had $1.5 million in letters 
of credit outstanding as guarantees of contract performance. 
As a normal incidence of the businesses in which the Company 
is engaged, various claims, charges and litigation are asserted 
or commenced against the Company. Lindgren is involved in a 
contract dispute with a prime contractor involving the assertion of 
certain construction delay damages of approximately $3.7 million. 
The project was completed in 2005. Lindgren vigorously denies 
responsibility for this delay and for these damages, and has 

17. Quarterly Financial information (unaudited)

asserted a claim against the prime contractor of $0.9 million 
based on damages suffered by Lindgren. Lindgren continues to 
aggressively defend its position and pursue its right to affirmative 
damages however, there can be no assurance of the outcome 
at this time. With respect to claims and litigation asserted or 
commenced against the Company, it is the opinion of Management, 
that final judgments, if any, which might be rendered against the 
Company are adequately reserved, covered by insurance, or are not 
likely to have a material adverse effect on its financial condition or 
results of operation.

Management’s Statement of Financial Responsibility

The Company’s Management is responsible for the fair presentation 
of the Company’s financial statements in accordance with 
accounting principles generally accepted in the United States 
of America, and for their integrity and accuracy. Management is 
confident that its financial and business processes provide accurate 
information on a timely basis.

Management, with the oversight of ESCO’s Board of Directors, has 
established and maintains a strong ethical climate in which the 
Company’s affairs are conducted. Management also has established 
an effective system of internal controls that provide reasonable 
assurance as to the integrity and accuracy of the financial 
statements, and responsibility for the Company’s assets. KPMG LLP, 
the Company’s independent accountants, reports directly to the 
Audit and Finance Committee of the Board of Directors. The Audit 
and Finance Committee has established policies consistent with 
newly enacted corporate reform laws for auditor independence. In 
accordance with corporate governance listing requirements of the 
New York Stock Exchange:

▶ A majority of Board members are independent of the Company  

and its Management

▶ All members of the key Board committees — the Audit and  
Finance, the Human Resources and Compensation and the  
Nominating and Corporate Governance Committees —  
are independent

▶ The independent members of the Board meet regularly without  

the presence of Management

▶ The Company has a clear code of ethics and conflict of interest 

policy to ensure that key corporate decisions are made by 
individuals who do not have a financial interest in the outcome, 
separate from their interest as Company officials

▶ The charters of the Board committees clearly establish their 

respective roles and responsibilities

▶ The Company has an ethics officer and an ombudsman hot line 
available to all domestic employees and all foreign employees 
have local ethics officers and access to the Company’s ombudsman

The Company has a strong financial team, from its executive 
leadership to each of its individual contributors. Management 
monitors compliance with its financial policies and practices over 
critical areas including internal controls, financial accounting and 
reporting, accountability, and safeguarding of its corporate assets. 
The internal audit control function maintains oversight over the 
key areas of the business and financial processes and controls, and 
reports directly to the Audit and Finance Committee. Additionally, 
all employees are required to adhere to the ESCO Code of Business 
Conduct and Ethics, which is monitored by the ethics officer.

Management is dedicated to ensuring that the standards of financial 
accounting and reporting that are established are maintained. The 
Company’s culture demands integrity and a commitment to strong 
internal practices and policies. 

The consolidated financial statements have been audited by KPMG 
LLP, whose report is included herein.

Management’s Report on internal Control Over Financial Reporting

The Company’s Management is responsible for establishing and 
maintaining adequate internal control over financial reporting (as 
defined in the Securities Exchange Act Rule 13a-15(f)). Our internal 
control over financial reporting is 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 in  
the United States of America.

Because of its inherent limitations, any system of internal control 
over financial reporting, no matter how well designed, may not 
prevent or detect misstatements due to the possibility that a 
control can be circumvented or overridden or that misstatements 
due to error or fraud may occur that are not detected. Also, because 
of changes in conditions, internal control effectiveness may vary 
over time.

Management assessed the effectiveness of the Company’s internal 
control over financial reporting as of September 30, 2006 using 
criteria established in Internal Control — Integrated Framework 
issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (COSO) and concluded that the Company 
maintained effective internal control over financial reporting as of 
September 30, 2006 based on these criteria, subject to the scope 
limitation with respect to Nexus and Hexagram as discussed in the 
following paragraph.

The Company acquired Nexus Energy Software, Inc. (Nexus) on 
November 29, 2005 and Hexagram, Inc. (Hexagram) on February 1, 
2006. As permitted by SEC guidance, Management excluded from its 
assessment of the effectiveness of the Company’s internal control 
over financial reporting as of September 30, 2006, Nexus’ and 
Hexagram’s internal control over financial reporting. Total assets 
related to Nexus as of September 30, 2006 were $3.7 million and 
revenues for the ten-month period subsequent to the acquisition 
(November 29, 2005 to September 30, 2006) were $9.6 million. 
Total assets related to Hexagram as of September 30, 2006 were 
$13.1 million and revenues for the eight-month period subsequent 
to the acquisition (February 1, 2006 to September 30, 2006) were 
$18.6 million. 

Our internal control over financial reporting as of September 30, 
2006, as well as our assessment of the effectiveness of our internal 
control over financial reporting as of September 30, 2006, have 
been audited by KPMG LLP, an independent registered public 
accounting firm, as stated in the report which is included herein.

Report of independent Registered public Accounting Firm

The Board of Directors and Shareholders 
ESCO Technologies Inc.:

We have audited the accompanying consolidated balance sheets 
of ESCO Technologies Inc. and subsidiaries (the Company) as of 
September 30, 2006 and 2005, and the related consolidated state-
ments of operations, shareholders’ equity, and cash flows for each 
of the years in the three-year period ended September 30, 2006. 
These consolidated financial statements are the responsibility of the 
Company’s management. Our responsibility is to express an opinion 
on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred  
to previously present fairly, in all material respects, the financial 
position of ESCO Technologies Inc. and subsidiaries as of  
September 30, 2006 and 2005, and the results of their operations 
and their cash flows for each of the years in the three-year period 
ended September 30, 2006, in conformity with U.S. generally 
accepted accounting principles.

As discussed in Note 1 to the consolidated financial statements,  
the Company adopted Statement of Financial Accounting Standards 
No. 123(R), “Share-Based Payment” effective October 1, 2005  
and the Company changed its method of quantifying errors in 2006.

We also have audited, in accordance with the standards of the 
Public Company Accounting Oversight Board (United States),  
the effectiveness of ESCO Technologies Inc.’s internal control over 
financial reporting as of September 30, 2006, based on criteria 
established in the Internal Control — Integrated Framework  
issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (COSO), and our report dated December 11,  
2006, expressed an unqualified opinion on management’s 
assessment of, and the effective operation of, internal control  
over financial reporting.

Report of independent Registered public Accounting Firm

The Board of Directors and Shareholders 
ESCO Technologies Inc.:

We have audited management’s assessment, included in the 
accompanying Management’s Report on Internal Control Over 
Financial Reporting, that ESCO Technologies Inc. (the Company) 
maintained effective internal control over the financial reporting 
as of September 30, 2006, based on criteria established in the 
Internal Control — Integrated Framework issued by the Committee 
of Sponsoring Organizations of the Treadway Commission 
(COSO). ESCO Technologies Inc.’s management is responsible for 
maintaining effective internal control over financial reporting and 
for its assessment of the effectiveness of internal control over 
financial reporting. Our responsibility is to express an opinion on 
management’s assessment and an opinion on the effectiveness of 
the Company’s internal control over financial reporting based on  
our audit.

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

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

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

In our opinion, management’s assessment that ESCO Technologies 
Inc. maintained effective internal control over financial reporting 
as of September 30, 2006, is fairly stated, in all material respects, 
based on criteria established in the Internal Control — Integrated 
Framework issued by COSO. Also, in our opinion, ESCO Technologies 
Inc. maintained, in all material respects, effective internal control 
over financial reporting as of September 30, 2006, based on criteria 
established in the Internal Control — Integrated Framework issued 
by COSO.

The Company acquired Nexus Energy Software, Inc. (Nexus)  
on November 29, 2005 and Hexagram, Inc. (Hexagram) on  
February 1, 2006, and management excluded from its assessment  
of the effectiveness of the Company’s internal control over financial 
reporting as of September 30, 2006, Nexus’ and Hexagram’s internal 
control over financial reporting. Total assets related to Nexus as 
of September 30, 2006 of $3.7 million and revenues for the ten-
month period subsequent to the acquisition (November 29, 2005 
to September 30, 2006) of $9.6 million and total assets related to 
Hexagram as of September 30, 2006 of $13.1 million and revenues 
for the eight-month period subsequent to the acquisition (February 1,  
2006 to September 30, 2006) of $18.6 million were included in 
the consolidated financial statements of ESCO Technologies Inc. 
and subsidiaries as of and for the year ended September 30, 2006. 
Our audit of internal control over financial reporting of ESCO 
Technologies Inc. also excluded an evaluation of the internal 
control over financial reporting of Nexus and Hexagram.

We also have audited, in accordance with the standards of the 
Public Company Accounting Oversight Board (United States), 
the consolidated balance sheets of ESCO Technologies Inc. and 
subsidiaries as of September 30, 2006 and 2005, and the related 
consolidated statements of operations, shareholders’ equity and 
cash flows for each of the years in the three-year period ended 
September 30, 2006, and our report dated December 11, 2006, 
expressed an unqualified opinion on those consolidated  
financial statements.
