Dear Fellow Shareholders, 

Overall, 2008 was a very good year.  The company delivered record results for the year.  Sales 
were the highest ever at $303 million, up 26.5 percent from last year.  Net income of $6.7 million 
and income per share of $0.98 (diluted) were also at record levels, in spite of a fourth quarter 
non-cash goodwill impairment charge of $2.8 million.  This charge was related to the filtration 
and industrial process cooling businesses and eliminated all remaining goodwill on the balance 
sheet.  Without this write down, earnings would have been $8.5 million or $1.24 per share 
(diluted). 

Contributions to this record setting result were not even across our business segments.  The 
piping systems business had a terrific year driven by strong domestic activity and very robust 
performance in the Middle East, supplemented by project specific revenue in India.  The 
filtration products business sales grew nicely but operating profit, even before the non-cash 
goodwill charge, was lower due to reduced margin from the marketplace and some higher one-
time expenses for relocating a U.S. operation to a more efficient U.S. manufacturing facility.  
The industrial process cooling equipment business faced a very difficult fourth quarter as the 
markets it serves were deeply impacted by the global recession.  Yet, excluding the non-cash 
goodwill charge, the group still improved profitability compared to the prior year.  The HVAC 
business worked actively on project backlog and, via solid execution, delivered a nice profit for 
the year. 

The Company’s backlog on January 31, 2009 was $108 million, down 24.8 percent from the 
prior year but still the second highest in Company history.  Part of the backlog decline was due 
to the normal progress on specific projects, such as the pipeline in India, and high sales in the 
fourth quarter.  The Company would not expect a project similar to the India project to be 
replaced in the backlog in sequential years.  Additionally, the difficult worldwide economic 
environment has caused some orders to be postponed or cancelled and has reduced the 
opportunities to obtain new work.  As a favorable sign, quoting activity in 2009 has been 
maintained at a reasonably high level but decision making by customers is slow, most likely due 
to general financial constraints and caution on expenditures.

Filtration Products Segment

Sales of $105 million increased 8.5 percent from the prior year, reflecting stronger sales for all 
product lines and a growing electric power generation customer base.  Gross margin was $11.4 
million or 10.8 percent of sales down from 14.2 percent of sales in 2007 as a result of the highly 
competitive marketplace, increasing cost of raw materials and higher cost of production labor at 
the Denmark operation. 

In order to increase the capacity and efficiency of the domestic pleated products offering, the 
operations at the Cicero, Illinois plant were relocated to a modern facility in Bolingbrook, Illinois 
in the summer of 2008.  Even though the relocation did add materially to our costs in the second 
half of the year, this investment should provide important benefits in the long term.  Also, in the 
fourth quarter, the filtration products business recorded a non-cash goodwill impairment charge 
of $1.7 million, bringing the loss from operations in 2008 to $2.9 million. 

Industrial Process Cooling Equipment Segment

Markets served by this segment saw significant contraction in the latter part of 2008 and into 
2009.  Compared to 2007, sales decreased by 12.6 percent to $31.7 million.  The sales decrease 
was primarily due to lower demand for its products in the plastics, printing and other industrial 
markets.  Even though demand was reduced, the business improved gross margin to 25.0 percent 
of sales from 23.4 percent of sales in 2007. 

For the fourth quarter, the business recorded a non-cash goodwill impairment charge of $1.1 
million.  This brought the loss from operations to $1.8 million, compared to a loss from 
operations in 2007 of $1.2 million.  Excluding the goodwill charge the loss from operations 
would have been $665,000, significantly reduced in comparison to the 2007 loss.  This was 
accomplished even though the group continued to invest in new product development necessary 
for growth and to meet environmental regulations in 2010 and beyond.

Corporate and Other

In December 2006, the Company created a new subsidiary, Midwesco Mechanical and Energy, 
Inc. to provide installation of HVAC systems for commercial and industrial buildings in the 
Chicago market area.  The President of this group, Ed Crylen, is an industry veteran and brings 
substantial skills in engineering and sales to this activity.  We hope to leverage technology 
developed in our other activities to improve the energy and environmental performance of the 
projects in which we participate.  The business has grown nicely and in 2008 sales increased to 
$14.1 million up from $1.8 million last year. 

During 2008 and early 2009 we made some important additions to our management team and 
Board of Directors.  In the spring of 2008, Tim Murphy joined our corporate staff as Vice 
President of Human Resources.  He brings a deep understanding of management talent 
assessment, development and succession planning, as well as how the area of human resources 
integrates into the overall business strategy. In the summer of 2008, Mark Foster joined the 
company as President of the filtration business segment.  His background fits well with the needs 
of our Filter group as we focus on improving margins, increasing operating profits and 
expanding our international footprint of the business. 

Most recently, in 2009, we announced the addition of Michael Gade and Mark Zorko to our 
Board.  We are extremely pleased to have access to their diverse business experience on our 
governance team and look forward to their counsel as we continue to grow the company’s 
activities. 

Turning to 2009, all the business units are focused on maximizing the results from existing 
backlog while adjusting cost structures to the new realities brought on by the uncertain depth and 
duration of a global recession.  In the most challenging business climate in decades, we are 
fortunate to have a strong leadership team to face the challenges ahead. 

OUR MISSION 

We are committed to provide products and services, in the markets we have chosen, of the 
highest quality and that contribute to a cleaner and more energy efficient global economy.  We 
dedicate ourselves to building a diverse, growing Company that offers its customers, employees 
and shareholders a way to benefit from working toward that goal.  We will do this while 
operating our business with the highest standards of ethics and professionalism and in 
compliance with all relevant laws and regulations.  Our policies will support the personal growth, 
health and well being of all our employees.  MFRI management and its employees are committed 
to the success of this mission. 

We deeply appreciate the hard work of our 1,500 employees around the world and your support 
and the confidence you have placed in us as stewards of your investment.  We hope you will take 
the time to learn more about our Company by visiting our web site www.mfri.com, reading our

Piping Systems Business 

Products and Services.  The Company engineers, designs, manufactures and sells specialty piping systems and leak 
detection and location systems.  Piping systems include (i) industrial and secondary containment piping systems for 
transporting chemicals, hazardous fluids and petroleum products, (ii) insulated and jacketed district heating and cooling 
(“DHC”) piping systems for efficient energy distribution to multiple locations from central energy plants, and (iii) oil and 
gas gathering flow lines and long lines for oil and mineral transportation.  The Company's leak detection and location 
systems are sold as part of many of its piping systems, and on a stand-alone basis to monitor areas where fluid intrusion 
may contaminate the environment, endanger personal safety, cause a fire hazard, impair essential services or damage 
equipment or property. 

The Company's piping systems are frequently custom fabricated to job site dimensions and/or incorporate provisions for 
thermal expansion due to varying temperatures.  This custom fabrication helps to minimize the amount of field labor 
required by the installation contractor.  Most of the Company's piping systems are produced for underground installations 
and, therefore, require trenching, which is done by unaffiliated installation contractors. 

Marketing.  The customer base for the Company's piping systems products is industrially and geographically diverse.  In 
the United States (“U.S.”) the Company employs a national sales manager and regional sales managers who use and assist 
a network of independent manufacturers' representatives, none of whom sells products that are competitive with the 
Company's piping systems.  Globally, the Company employs direct sales force as well as an exclusive agent network for 
several countries in the Middle and Far East to market and sell products and services. 

Patents and Trademarks.  The Company owns several patents covering its piping and electronic leak detection systems.  
The patents are not material either individually or in the aggregate to the overall business because the Company believes 
sales in the business would not be materially reduced if patent protection were not available.  The Company owns 
numerous trademarks connected with its piping and leak detection systems business including the following: Perma-
Pipe®, Chil-Gard®, Double-Quik®, Escon-A®, FluidWatch®, Galva-Gard®, Poly-Therm®, Pal-AT®, Stereo-Heat®, 
LiquidWatch®, PalCom®, Xtru-therm®, Auto-Therm®, Pex-Gard™, and Ultra-Therm®.  The Company also owns 
United Kingdom trademarks for Poly-Therm®, Perma-Pipe® and Ric-Wil®, Denmark trademark for Ric-Wil®, France 
trademark for Perma-Pipe®, Germany trademark for Perma-Pipe® and a Canadian trademark for Ric-Wil®. 

Backlog.  As of January 31, 2009, the backlog (uncompleted firm orders) amount was $52,385,000, substantially all of 
which is expected to be completed in 2009.  As of January 31, 2008, the amount of backlog was $65,810,000. 

Raw Materials.  The basic raw materials used in the production of products are pipes and tubes made of carbon steel, 
alloy, copper, ductile iron and plastics and various chemicals such as polyols, isocyanate, urethane resin, polyethylene and 
fiberglass, mostly purchased in bulk quantities.  The Company believes there are currently adequate supplies or sources of 
availability of the needed raw materials. 

The sensor cables used in the leak detection and location systems are manufactured to the Company's specifications by 
companies regularly engaged in the business of manufacturing such cables.  The Company owns patents for some of the 
features of its sensor cables.  The Company assembles the monitoring component of the leak detection and location 
system from standard components purchased from many sources. 

Competition.  The piping systems business is highly competitive.  The Company believes its principal competition in this 
segment consists of between ten and twenty major competitors and more small competitors.  The Company believes 
quality, service, a comprehensive product line and price are the key competitive factors.  The Company also believes it 
has a more comprehensive line for DHC than any of its competitors.  Certain competitors of the Company have greater 
financial resources and some have cost advantages as a result of manufacturing a limited range of products. 

2

Government Regulation.  The demand for the Company's leak detection and location systems and secondary containment 
piping systems, a small percentage of the total annual piping sales, is driven by federal and state environmental regulation 
with respect to hazardous waste.  The Federal Resource Conservation and Recovery Act require, in some cases, that the 
storage, handling and transportation of certain fluids through underground pipelines feature secondary containment and 
leak detection.  The National Emission Standard for Hydrocarbon Airborne Particulates requires reduction of airborne 
volatile organic compounds and fugitive emissions.  Under this regulation, many major refineries are required to recover 
fugitive vapors and dispose of the recovered material in a process sewer system, which then becomes a hazardous 
secondary waste system that must be contained.  Although there can be no assurances as to the ultimate effects of these 
governmental regulations, the Company believes it may increase the demand for its piping systems products. 

Filtration Products Business 

Products and Services.  The Company manufactures and sells a wide variety of filter elements for cartridge collectors and 
baghouse air filtration and particulate collection systems.  The principal types of industrial air filtration and particulate 
collection systems in use are baghouses, cartridge collectors, electrostatic precipitators, scrubbers and mechanical 
collectors.  This equipment is used to eliminate particulate from the air by passing particulate laden gases through fabric 
filters (filter bags) or pleated media filter elements, in the case of baghouses or cartridge collectors, between electrically 
charged collector plates, in the case of electrostatic precipitators and contact with liquid reagents (scrubbers).  The 
Company manufactures filter elements in standard industry sizes, shapes and filtration media and to custom specifications, 
maintaining manufacturing standards for more than 10,000 styles of filter elements to suit substantially all industrial 
applications.  Filter elements are manufactured from industrial yarn, fabric and paper purchased in bulk.  Most filter 
elements are produced from cellulose, acrylic, fiberglass, polyester, aramid, laminated membranes, or polypropylene 
fibers.  The Company also manufactures filter elements from more specialized materials, sometimes using special 
finishes.

The Company markets numerous filter-related products and accessories used during the installation, operation and 
maintenance of cartridge collectors and baghouses, including wire cages used to support filter bags, spring assemblies for 
proper tensioning of filter bags and clamps and hanger assemblies for attaching filter elements.  In addition, the Company 
markets other hardware items used in the operation and maintenance of cartridge collectors and baghouses.  The Company 
also provides maintenance services, consisting primarily of air filtration system inspection and filter element replacement, 
using a network of independent contractors. 

Over the past three years, the Company's filtration products business has supplied filter elements to more than 4,000 user 
locations.  The Company has particular expertise in supplying filter bags for use with electric arc furnaces in the steel 
industry.  The Company believes its production capacity and quality control procedures make it a leading supplier of filter 
bags to large users in the electric power industry.  Orders from the electric power industry tend to be substantial in size, 
but are usually at lower margins than from other industries. 

Marketing.  The customer base is industrially and geographically diverse.  These products and services are used primarily 
by operators of utility and industrial coal-fired boilers, incinerators and cogeneration plants and by producers of metals, 
cement, chemicals and other industrial products. 

The Company has an integrated sales program for its filtration products business, which consists of field-based sales 
personnel, manufacturers' representatives, a telemarketing operation and computer-based customer information systems.  
The Company believes the computer-based information systems are instrumental in increasing sales of filter-related 
products and accessories and maintenance services, as well as sales of filter elements.  The Company’s filtration products 
are marketed domestically under the names, Midwesco Filter and TDC Filter Manufacturing. 

The Company markets its U.S. manufactured filtration products internationally using domestically based sales resources 
to target major users in foreign countries.  The Denmark filtration facility markets pleated filter elements throughout 
Europe and Asia, primarily to original equipment manufacturers. 

Trademarks.  The Company owns the following trademarks covering its filtration products:  Seamless Tube®, Leak 
Seeker®, Prekote®, We Take the Dust Out of Industry®, Pleatkeeper®, Pleat Plus® and EFC®.

Backlog.  The backlog amount was $35,549,000 at January 31, 2009 and $38,160,800 at January 31, 2008.  Certain 
customers have placed orders that are deliverable over multiple years.  Therefore, approximately $9,109,000 of the 
backlog as of January 31, 2009 is not expected to be completed in 2009. 

Raw Materials.  The basic raw materials used are industrial fibers and media supplied by leading producers of such 
materials.  The majority of raw materials purchased are woven fiberglass fabric, yarns for manufacturing Seamless Tube® 
products and other woven, felted, spun bond, laminated membranes, and cellulose media.  Only a limited number of 
suppliers are available for some of these materials.  The Company believes supplies of all materials are adequate to meet 
current demand. 

Competition.  The filtration products business is highly competitive.  In addition, new installations of cartridge collectors 
and baghouses are subject to competition from alternative technologies.  The Company believes, based on domestic sales, 
its principal competitors in this segment consist of approximately five major competitors and at least 50 smaller 
competitors, most of which are doing business on a regional or local basis.  In Europe, several companies supply filtration 
products, and the Company is a relatively small participant in that market.  Some of the Company's competitors have 
greater financial resources than the Company. 

The Company believes quality, service, and price are the most important competitive factors in its filtration products 
business.  Often, a manufacturer has a competitive advantage when its products have performed successfully for a 
particular customer in the past.  Additional effort is required by a competitor to market products to such a customer.  In 
certain applications, the Company's proprietary Seamless Tube® product and customer support provide the Company with 
a competitive advantage.  Certain competitors may have a competitive advantage with respect to their own proprietary 
products and processes, such as specialized fabrics and fabric finishes.  In addition, some competitors may have cost 
advantages with respect to certain products as a result of lower wage rates and/or greater vertical integration. 

Government Regulation.  The Company's filtration products business is substantially dependent upon governmental 
regulation of air pollution at the federal and state levels.  Federal clean air legislation requires compliance with national 
primary and secondary ambient air quality standards for specific pollutants, including particulate.  The states are primarily 
responsible for implementing these standards and, in some cases, have adopted more stringent standards than those issued 
by the U.S. Environmental Protection Agency under the Clean Air Act Amendments of 1990 ("Clean Air Act”). 

Industrial Process Cooling Equipment Business 

Products and Services.  The Company engineers, designs, manufactures and sells cooling and temperature control 
equipment for industrial applications.  The Company believes it manufactures the most complete line of chillers available 
in its primary markets.  Products include: chillers (portable and central); cooling towers; plant circulating assemblies; hot 
water, hot oil, and negative pressure temperature controllers; water treatment equipment; specialty cooling devices for 
printing presses and ink management; and replacement parts and various accessories relating to the foregoing products.
The Company's products are used to optimize manufacturing productivity by quickly removing heat from manufacturing 
processes and providing accurate temperature control.  The Company combines chillers and/or cooling towers with plant 
circulating systems to create plant-wide systems that account for a large portion of its business.  The Company specializes 
in customizing cooling systems and computerized controls according to customer specifications. 

The principal markets for the Company’s cooling and temperature control products are thermoplastics processing and the 
printing industries.  The Company also sells its products to original equipment manufacturers, to other cooling 
manufacturers on a private branded basis and to manufacturers in the laser, metallizing, machine tool industries, and 
various other industries. 

Marketing.  Generally, the Company sells its products in the global thermoplastics and printing markets as well as to 
other industrial applications that require specialized heat transfer equipment.  Domestic thermoplastics processors are the 
largest market served by the Company, representing the core of its business.  The Company's cooling products are sold 
through independent manufacturers' representatives on an exclusive territory basis.  Temperature control products are sold 
through a network of independent dealers/distributors in major industrial markets. 

4

The Company believes the total annual U.S. market for water cooling equipment in the plastics industry is over $100 
million, and the Company is one of the three largest suppliers of such equipment to the plastics industry.  The Company 
believes the plastics industry is a mature industry with growth generally consistent with that of the national economy.  The 
Company has increased sales to non-plastics industries that require specialized heat transfer equipment, usually sold to 
end users as a package by the supplier of the primary equipment, particularly in the laser industry, metallizing industry, 
and machine tool industries.  The Company believes the size of this market is more than $200 million annually.  The 
original equipment manufacturer generally distributes products to the end user in these markets. 

Trademarks.  The Company has registered the trademarks Thermal Care®, AWS® and Applied Web Systems®. 

Backlog.  As of January 31, 2009, the backlog amount was $3,835,000, substantially all of which is expected to be 
completed in 2009.  As of January 31, 2008, the amount of backlog was $6,315,000. 

Raw Materials.  The Company uses prefabricated sheet metal and subassemblies manufactured by both Thermal Care and 
outside vendors for temperature controller fabrication.  Cooling towers are manufactured using fiberglass and hardware 
components purchased from several sources.  The Company believes its access to sheet metal, subassemblies, fiberglass 
and hardware components is adequate. 

Competition.  The Company believes there are about 15 competitors selling cooling equipment in the domestic plastics 
market.  The Company further believes three manufacturers, including the Company, account for approximately 50% of 
the domestic plastics cooling equipment market.  Many international customers, with relatively small cooling needs, are 
able to purchase small refrigeration units (portable chillers), which are manufactured in their respective local markets at 
prices below that which the Company can offer due to issues such as freight cost and customs duties.  However, such local 
manufacturers often lack the technology and products needed for plant-wide cooling systems.  The Company believes its 
reputation for producing quality plant-wide cooling products results in a significant portion of the Company’s business in 
the cooling product area.  Temperature control units, which are sold globally, compete with both local and European 
manufacturers.  The quality, reliability, features and range of temperature control applications addressed by the 
Company’s products provide a competitive advantage. 

The Company believes quality, service, a comprehensive product line and price are the key competitive factors in its 
industrial process cooling equipment business.  The Company believes it has a more comprehensive line of cooling 
products than any of its competitors.  Certain competitors of the Company have cost advantages as a result of 
manufacturing in non-union shops and offering a limited range of products.  Some of the Company's competitors may 
have greater financial resources than the Company. 

Government Regulation.  The Company does not expect compliance with federal, state and local provisions regulating 
the discharge of materials into the environment or otherwise relating to the protection of the environment to have a 
material effect on capital expenditures, earnings or the Company’s competitive position.  Management is not aware of the 
need for any material capital expenditures for environmental control facilities for the foreseeable future.  Regulations, 
promulgated under the Clean Air Act, prohibit the manufacture and sale of certain refrigerants.  The Company does not 
use these refrigerants in its products.  The Company expects that suitable refrigerants conforming to federal, state and 
local laws and regulations will continue to be available to the Company, although no assurances can be given as to the 
ultimate effect of the Clean Air Act and related laws on the Company. 

Other Business 

Corporate and other activity includes activity for the installation of HVAC systems.  This activity is not sufficiently large 
enough to constitute a reportable segment.  During 2008, this subsidiary’s net sales were $14,142,000, 4.7% of 
consolidated net sales. 

Backlog.  At January 31, 2009, the backlog amount for other business was $16,051,000, substantially all of which is 
expected to be completed in 2009 and was $33,179,000 at January 31, 2008.

Employees 

As of February 28, 2009, the Company had 1,501 full-time employees, of whom 51.5% worked outside the U.S. 

International

The Company’s international operations as of January 31, 2009 include subsidiaries in four foreign countries on three 
continents.  The Company’s international operations contributed approximately 30.7% of revenues in 2008 and 20.6% of 
revenues in 2007. 

Refer to the Business Segment descriptions on pages 1 through 5 above and Note 1 - Description of the Business and 
Segment Information in the Notes to Consolidated Financial Statements for additional information on international 
activities.  International operations are subject to certain risks inherent in conducting business in foreign countries, 
including price controls, exchange controls, limitations on participation in local enterprises, nationalization, expropriation 
and other governmental action, and changes in currency exchange rates.

Item 1A.  Risk Factors 

Competition.  The businesses in which the Company is engaged are highly competitive.  Many of the competitors are 
larger and have more resources than the Company.  Many of the Company’s products are also subject to competition from 
alternative technologies and alternative products.  To the extent the Company relies upon a single source for key 
components of several of its products, the Company believes there are alternate sources available for such components; 
however, there can be no assurance that the interruption of supplies of such components would not have an adverse effect 
on the financial condition of the Company, and that the Company, if required to do so, would be able to negotiate 
agreements with alternative sources on acceptable terms. 

International rapid growth.  Potential international future rapid growth could place a significant strain on management, 
operations and financial systems as well as on the Company’s ability to attract and retain competent employees.  Future 
operating results will depend in part on the Company’s ability to continue to implement and improve operating and 
financial controls and management information systems.  Failure to effectively manage growth could materially adversely 
impact the business, financial conditions and results of operations. 

Changes in Government Policies and Laws, Worldwide Economic Conditions.  International sales represent an 
increasing portion of the Company’s total sales and continued growth and profitability may involve further international 
expansion.  The Company’s financial results could be affected by changes in trade, monetary and fiscal policies, laws and 
regulations, or other activities of U.S. and non-U.S. governments, agencies and similar organizations.  These conditions 
include but are not limited to changes in a country’s or region’s economic or political conditions, trade regulations
affecting production, pricing and marketing of products, local labor conditions and regulations, reduced protection of  

7

intellectual property rights in some countries, changes in the regulatory or legal environment, restrictions on currency 
exchange activities, burdensome taxes and tariffs and other trade barriers.  International risks and uncertainties, including 
changing social and economic conditions as well as terrorism, political hostilities and war, could lead to reduced 
international sales and reduced profitability associated with such sales. 

Government regulation.  The demand for the Company’s leak detection and location systems and secondary containment 
piping systems is driven primarily by government regulation with respect to hazardous waste.  Laws such as the Federal 
Resource Conservation and Recovery Act and standards such as the National Emission Standard for Hydrocarbon 
Airborne Particulates have increased the demand for the Company’s leak detection and location and secondary 
containment piping systems.  The Company’s filtration products business, to a large extent, is dependent on governmental 
regulation of air pollution at the federal and state levels.  The Company believes that continuing growth in the sale of 
filtration products and services will be materially dependent on continuing enforcement of environmental laws such as the 
Clean Air Act.  Although changes in such environmental regulations could significantly alter the demand for the 
Company’s products and services, the Company does not believe such a change is likely to decrease demand in the 
foreseeable future. 

Economic Factors.  The current economic slowdown and recession in the U.S. and worldwide economies is likely to 
further decrease the demand for products and adversely affect sales.  Because economic and market conditions vary 
within the Company’s business segments, the Company’s future performance by business segment will also vary.  In 
addition, the Company is exposed to fluctuations in currency exchange rates and commodity prices.  Failure to 
successfully manage any of these risks could have an adverse impact on the Company’s financial position, results of 
operations and cash flows. 

Also, the cash surrender value of life insurance policies owned by the Company for the purpose of recovering the costs of 
deferred compensation programs for several current officers of the Company is affected by the market value of the 
underlying investments.  Adverse market conditions may result in a decline in the cash surrender value of these life 
insurance policies, which would result in a non-cash expense that would reduce net income. 

Customer Access to Capital Funds.  Uncertainty about current economic market conditions in the U.S. and globally poses 
risks that the Company’s customers may postpone spending for capital improvement and maintenance projects in response 
to tighter credit markets or negative financial news which could have a material negative effect on the demand for the 
Company’s products. 

Backlog.  The Company defines backlog as the revenue value in dollars attributed to confirmed customer purchase orders 
that have not yet been recognized as revenues.  However, by industry practice, orders may be canceled or modified at any 
time.  When a customer cancels an order, the customer is responsible for all finished goods, all direct and indirect costs 
incurred, and also for a reasonable allowance for anticipated profits.  No assurance can be given that these amounts will 
be received after cancellation.  The current backlog also includes contracts which have scheduled shipping dates beyond 
the upcoming fiscal year and, as such, only a portion of the current backlog represents expected annual revenues for 2009.  
Any cancellation or delay in orders may result in lower than expected revenues. 

Financing.  If there were an event of default under the Company’s current revolving credit facility, the holders of the 
defaulted debt could cause all amounts outstanding with respect to that debt to be due and payable immediately.  The 
Company cannot assure that the assets or cash flow would be sufficient to fully repay amounts due under any of the 
financing arrangements, if accelerated upon an event of default, or, that the Company would be able to repay, refinance or 
restructure the payments under any such arrangements.  Complying with the covenants under the Company’s revolving 
credit facility may limit management’s discretion by restricting options such as: 

incurring additional debt; 
entering into certain transactions with affiliates; 

(cid:120)
(cid:120)
(cid:120) making investments or other restricted payments; 
paying dividends or make other distributions; and  
(cid:120)
creating liens. 
(cid:120)

Any additional financing the Company may obtain could contain similar or more restrictive covenants.  The Company’s 
ability to comply with any covenants may be adversely affected by general economic conditions, political decisions, 
industry conditions and other events beyond management’s control. 

Percentage-of-completion method of accounting.  The Company measures and recognizes a portion of revenue and 
profits under the percentage-of-completion accounting methodology.  This methodology allows revenue and profits to be 
recognized proportionally over the life of a contract by comparing the amount of the cost incurred to date against the total 
amount of cost expected to be incurred.  The effect of revisions to revenue and total estimated cost is recorded when the 
amounts are known and can be reasonably estimated.  These revisions can occur at any time and could be material.  On a 
historical basis, management believes that reasonably reliable estimates of the progress towards completion on long term 
contracts have been made.  However, given the uncertainties associated with these types of contracts, it is possible for 
actual cost to vary from estimates previously made, which may result in reductions or reversals of previously recorded 
revenue and profits. 

Internal Controls.  As a public company, the Company is required to comply with the reporting obligations of the 
Securities Exchange Act of 1934 and is required to comply with Section 404 of the Sarbanes-Oxley Act (“SOX 404”).  
The Company’s failure to prepare and disclose this information in a timely manner could subject it to penalties under 
Federal securities laws, expose it to lawsuits and restrict its ability to access financing.  If the Company fails to achieve 
and maintain the adequacy of internal controls, and the Company, or its auditors, are unable to assert that the Company’s 
internal control over financial reporting is effective, the Company could be subject to regulatory sanctions or lose investor 
confidence in the accuracy and completeness of the financial reports.  In addition, the Company has experienced, and may 
experience, incremental costs of compliance with SOX 404.

General and administrative expenses increased 28.0% to $30,818,000 from $24,083,000 in 2007.  The increase was 
mainly due to increased profit-based management incentive expense, increased bank fees, additional stock compensation 
expense partially offset by a decrease in the deferred compensation expense of $495,000. 

The Company recognized a $2,788,000 non-cash charge for goodwill impairment, which was recorded as part of 
continuing operations.  In accordance with the Financial Accounting Standards Board’s Statement of Financial 
Accounting Standards (“SFAS”) No. 142 (“SFAS 142”), during the first quarter each year, the Company reviews the 
carrying value of goodwill.  The evaluation of impairment involved comparing the current fair value of the business to the 
carrying value.  The Company used a discounted cash flow model to determine the current fair value of its reporting units.  
A number of significant assumptions and estimates were involved in the application of the model to forecast operating 
cash flows, including markets and market share, sales volumes and prices, costs to produce and working capital changes.  
Management considered historical experience and all available information at the time the fair values of its reporting units 
were estimated.  However, actual fair values that could be realized in a transaction may differ from those used to evaluate 
the impairment of goodwill. 

The recently completed goodwill impairment assessment followed the fourth quarter 2008 worsening of economic 
conditions.  These conditions impacted both the risks considered and the calculations made.  The assessment considered 
uncertainty about current economic market conditions in the U.S. and globally that may pose risks to the Company’s 
customer demand.  Customers may postpone spending for capital improvement and maintenance projects in response to 
tighter credit markets or negative financial news.  The distressed financial markets caused the discount rates used in 
calculating the present value of estimated future cash flows to be higher than a year ago.  These conditions were reflected 
in the Company’s goodwill impairment assessment. 

As a result, the estimated future cash flows of the filtration products business (whose goodwill was $1,688,000) and the 
industrial process cooling equipment business (whose goodwill was $1,100,000) were both lower than when goodwill 
impairment testing was done a year ago.  All of the Company’s goodwill was deemed impaired and was written off with a 
noncash impairment charge.

The Company’s worldwide effective income tax rate for 2008 was 17.0%.  The 2008 tax rate decreased as compared to 
2007 mainly due to the impact of tax-free foreign income. 

Net income rose to $6,689,000 in 2008 from a net loss of $298,000 in 2007 primarily due to increased sales, the reasons 
summarized above and discussed in more detail below. 

2007 Compared to 2006 

Net sales were a record at $239,487,000 in 2007, an increase of 12.2% from $213,471,000 in 2006.  Sales increased in the 
piping systems and the filtration products businesses while the industrial process cooling business decreased. 

Net income for 2007 was sharply down primarily due to the following factors: 

Piping Systems:

(cid:120) During the fourth quarter 2007 the U.A.E. facility received a customer contract change to a very large pipeline 
project which reduced the project scope as well as net sales and net income.  This, along with significant 
unplanned cost to finish product significantly reduced net income.  Also, overhead additions were made in 
marketing, sales and operations to bolster the skills and resources of this rapidly growing unit. 

(cid:120) At the New Iberia, Louisiana facility, half the third quarter 2007 was devoted to research and development of a 

new product for a major customer application.  While progress was made, the effort was not successful and work 
on production of other customer orders resumed.

(cid:120) Margin erosion occurred due to higher prices for raw materials, specifically steel and plastic resins, which could 

not be passed along to the customers under existing orders. 

14 

Filtration Products:

(cid:120) The recently acquired factory in South Africa had a manufacturing error which necessitated the rework and 

replacement of a sizeable customer order. 

(cid:120) High factory labor and warranty costs along with software implementation expenses at the European pleated filter 

operation significantly affected results. 

(cid:120) Ongoing market pricing pressure in the U.S. and increasing raw materials prices worldwide also reduced margin 

in both pleated and bag products. 

Industrial Process Cooling: 

(cid:120)

(cid:120)

Incurred increased expenses related to unanticipated development and field modification costs for certain 
refrigeration equipment previously sold to its customers.  The product was temporarily removed from the market 
which reduced sales.  Product enhancements made in Q3 and Q4, although costly to the Company, were 
successful and led to reintroduction of the product to the market. 
Significant expenditures were made and continue to be made in new product design and development as well as 
engineering staff recruitment. 

(cid:120) Gross profit was reduced primarily due to material cost increases which were not completely offset by selling 

price increases. 

Other significant incremental expenses in 2007 not incurred in 2006:

(cid:120)
(cid:120)
(cid:120)

2007 expenses to comply with SOX 404, were $938,000 compared to $9,000 in 2006. 
Start-up expenses of $664,000 for the newly created HVAC subsidiary. 
Incremental vacation expense of $422,000 to adjust the accrual for vacation pay to agree with the plan 
requirements. 

(cid:120) Additional stock compensation expense of $365,800. 
(cid:120)

Increase of $726,000 or 32.5% from the prior year in consolidated warranty expense, mainly due to the reasons 
previously detailed by business segment. 

Because of the above factors and other occurrences, gross profit of $41,249,000 in 2007 decreased 7.1% from 
$44,405,000 in 2006.  Gross margin for 2007 declined to 17.2% from 20.8% in 2006. 

Tax rate for 2007 was 158.3% mainly due to the valuation allowance for state and foreign net operating losses as 
described in Income Taxes below.

2008 Compared to 2007 

Net sales of $151,792,000 for 2008 increased 45.6% from $104,273,000 in 2007, attributed to achieving the Company’s 
market share in the U.A.E., as well as other Gulf Cooperating Council countries such as Qatar, Kuwait, and Bahrain.  The 
U.A.E. facility’s net sales were $54,454,000 in the current year compared to $22,339,000 in 2007.  As of January 31, 
2009, the Company had completed over half of the India pipeline contract. 

Gross margin as a percent of net sales increased to 24.9% in 2008 from 18.2% in 2007, primarily due to production 
efficiencies in both domestic and international operations.  Margins in the U.A.E. improved from increased volume 
without corresponding increases in fixed expenses.

Total selling expense increased to $2,840,000 or 1.9% of net sales in 2008 from $2,297,000 or 2.2% of net sales in 2007.  
The dollar increase was mainly due to increased staffing primarily in the U.A.E. 

General and administrative expense increased to $10,994,000 or 7.2% of net sales in 2008 from $6,032,000 or 5.8% of net 
sales in 2007.  The increase was primarily due to the increase in profit-based management incentive expense, additional 
administrative costs in the India pipeline project, and increased bank fees offset by a gain in foreign currency exchange. 

2007 Compared to 2006 

Net sales increased 26.9% to $104,273,000 in 2007 from $82,166,000 in 2006.  This increase was primarily driven by 
$22,339,000 in 2007 sales at the U.A.E. facility compared to $2,792,000 in sales from the U.A.E. in the prior year, 
partially offset by decreased sales to oil and gas customers.  At the New Iberia facility, half the 2007 third quarter was 
devoted to research and development of a new product for a major customer application.  While progress was made, the 
effort was not successful.  In the middle of October 2007, the New Iberia facility resumed work on production of 
customer orders. 

Gross margin as a percent of net sales decreased to 18.2% in 2007 from 20.4% in 2006, primarily due to lower sales to oil 
and gas customers, which tend to have a higher margin over other customers and the additional product development work 
for oil and gas in the third quarter.  Gross margin at the U.A.E. facility was lower than the piping systems business’s 
average during its first year of rapid growth, driven in part by production of a particularly challenging order for an oil and 
gas customer. 

Total selling expense increased to $2,297,000 or 2.2% of net sales in 2007 from $1,560,000 or 1.9% of net sales in 2006.  
Selling expense in the U.A.E. increased to $750,000 in 2007 from $177,000 in 2006.  The increased expense was mainly 
due to additional staffing primarily in the U.A.E., and the addition of an international sales manager based in the U.S. 

General and administrative expense increased to $6,032,000 or 5.8% of net sales in 2007 from $5,653,000 or 6.9% of net 
sales in 2006.  The dollar increase in general and administrative expenses was primarily due to increased staffing in the 
U.A.E. to support the location’s growth, and increased staffing in the U.S. 

Filtration Products Business 

The timing of large orders can have a material effect on net sales and gross profit from period to period.  Pricing on large 
orders was generally extremely competitive and therefore resulted in relatively low gross margins. 

The Company’s filtration products business is dependent on government regulation of air quality at the federal and state 
levels.  The Company believes that growth in the sale of its filtration products and services will be materially dependent 
on continued enforcement of environmental laws such as the Clean Air Act.  Although there can be no assurance what the 
ultimate effect of the Clean Air Act will be on the Company’s filtration products business, the Company believes the 
Clean Air Act is likely to have a positive long-term effect on demand for the Company’s filtration products and services.

Net sales increased 8.5% to $105,390,000 in 2008 from $97,120,000 in 2007.  This increase was due to the result of 
higher unit volume in all product lines, primarily from domestic power generation customers.

Gross  margin  as  a  percent  of  net  sales  decreased  to  10.8%  in  2008  from  14.2%  in  2007,  primarily  due  to  the  highly 
competitive marketplace, increasing cost of raw materials, temporary manufacturing inefficiencies during the relocation to 
the  Bolingbrook,  IL  facility  and  higher  cost  of  production  labor  at  the  Denmark  facility  resulting  from  increased 
headcount. 

Selling expense increased to $7,575,000 or 7.2% of net sales in 2008 from $6,873,000 or 7.1% of net sales in 2007.  The 
increase in selling expense was primarily due to additional selling personnel, and increased travel and advertising 
expenses.

General and administrative expenses increased to $5,097,000 or 4.8% of net sales from $4,682,000 or 4.8% of net sales in 
2007.  The dollar increase was primarily due to the hiring of several new senior managers and increased professional 
service expense. 

For the fourth quarter and fiscal year ended January 31, 2009, the filtration products business recorded a non-cash 
impairment charge of $1,688,000 in connection with the annual assessment of goodwill in accordance with SFAS 142.
See Note 2 in the Notes to Consolidated Financial Statements for details with respect to impairment change incurred 
during 2008. 

2007 Compared to 2006 

Net sales increased 12.5% to $97,120,000 in 2007 from $86,362,000 in 2006.  This increase was the result of increased 
sales in all product lines and geographic areas, primarily the result of a growing electric power generation customer base. 

Gross margin as a percent of net sales decreased to 14.2% in 2007 from 18.8% in 2006, primarily due to the highly 
competitive marketplace, increasing cost of raw materials, customer mix and additional post-sale customer support costs, 
including rework and replacement of a sizeable customer order produced in the South African facility.  The cost of 
production labor at the Denmark facility was higher than in prior years. 

Selling expense increased to $6,873,000 or 7.1% of net sales in 2007 from $6,541,000 or 7.6% of net sales in 2006.  The 
dollar increase in selling expense was primarily due to increased commission expense related to higher sales and increased 
advertising expense. 

General and administrative expenses increased to $4,682,000 or 4.8% of net sales from $4,415,000 or 5.1% of net sales in 
2006.  The dollar increase was the result of additional staffing in the foreign locations and the ERP software 
implementation expenses incurred at the Denmark facility.

Net sales decreased 12.6% to $31,738,000 in 2008 from $36,327,000 in 2007.  The decrease was primarily due to lower 
demand for its products in the global plastic and domestic printing markets. 

Gross margin as a percentage of net sales increased to 25.0% in 2008 from 23.4% in 2007, primarily due to significant 
reduction in post-sale customer support costs, partially offset by lower sales volume relative to fixed costs.

Selling expense decreased to $4,135,000 or 13.0% of net sales in 2008 from $5,100,000 or 14.0% of net sales in 2007.  
This was primarily driven by decreased commission expense from lower sales, and a reduction in staffing in the second 
half of 2007 and during 2008. 

General and administrative expense decreased to $4,449,000 or 14.0% of net sales in 2008 from $4,635,000 or 12.8% of 
net sales in 2007.  This dollar decrease was primarily due to the gain on the sale of property and staffing reductions, 
partially offset by increased new product development engineering expenses. 

For the fourth quarter and fiscal year ended January 31, 2009, the industrial process cooling equipment business recorded 
a non-cash impairment charge of $1,100,000 in connection with the annual goodwill assessment in accordance with SFAS 
142.  See Note 2 in the Notes to Consolidated Financial Statements for details with respect to impairment change incurred 
during 2008.

2007 Compared to 2006 

Net sales decreased 11.7% to $36,327,000 in 2007 from $41,161,000 in 2006.  The decrease was primarily due to lower 
demand  for  its  products  in  major  market  sectors  and  a  temporary  halt  in  sales  of  a  new  central  chilling  product  line, 
launched in 2005, to resolve some performance issues.  The product line was re-launched in the fourth quarter of 2007. 

Gross margin as a percentage of net sales decreased to 23.4% in 2007 from 27.4% in 2006, primarily due to material cost 
increases,  which  were  not  completely  offset  by  selling  price  increases,  lower  sales  volume  over  which  to  spread  fixed 
manufacturing overhead expenses and field modification costs for a central chilling product line.  Manufacturing staff was 
reduced by 12% in the fourth quarter 2007 to better balance production expenses with demand. 

Selling expense decreased to $5,100,000 or 14.0% of net sales in 2007 from $5,713,000 or 13.9% of net sales in 2006.  
The decrease was due to reduced commission expense from lower sales. 

General and administrative expense increased to $4,635,000 or 12.8% of net sales in 2007 from $4,339,000 or 10.5% of 
net sales in 2006.  This increase was primarily due to increased professional costs including employment-related hiring 
expenses and engineering consulting fees related to new product development. 

General Corporate and Other 

2008 Compared to 2007 

Net sales increased to $14,146,000 in 2008 from $1,767,000 in 2007.  The 2008 and 2007 net sales related to the start-up 
of the HVAC systems business. 

General corporate expense included interest expense and general and administrative expenses that were not allocated to 
the business segments. 

General and administrative expense increased 21.8% to $10,278,000 in 2008 from $8,733,000 in 2007, and decreased as a 
percentage of consolidated net sales to 3.4% in 2008 from 3.6% in 2007.  The dollar increase was mainly due to the 
increased profit-based management incentive expense, incremental expenses relating to stock compensation expense of 
$241,000, and additional staffing.  These expenses were partially offset by decreased deferred compensation expense of 
$495,000.  The deferred compensation plan was affected by the market value of the underlying investments.  Since the 
underlying investment declined, the Company’s liability to the employees in the plan decreased. 

Interest expense, net of capitalized interest, increased 17.7% to $2,834,000 in 2008 from $2,408,000 in 2007 primarily 
due to increased borrowings.  Capitalized interest of $152,000 was recorded in 2008 and was attributable to the building 
preparations for the relocation of the filtration products business’ Cicero, Illinois operations to Bolingbrook, Illinois which
occurred in the second and third quarters of 2008.  The building was purchased in March 2008 for $6,400,000, and 
improvements and modifications cost an additional $3,159,000. 

18 

2007 Compared to 2006 

The 2007 net sales of $1,767,000 related to the start-up of the HVAC systems business.  The 2006 net sales of $3,782,000 
were related to other corporate business. 

General and administrative expense increased 20.6% to $8,733,000 in 2007 from $7,242,000 in 2006, and increased as a 
percentage of consolidated net sales to 3.6% in 2007 from 3.4% in 2006.  The increase was mainly due to incremental 
expenses of $929,000 incurred to comply with SOX 404 (including consulting fees) that were not incurred in 2006, the 
inclusion of $664,000 of the general and administrative expense from the newly created subsidiary that installs HVAC 
systems, and additional stock compensation expense of $365,800 compared to the prior year.  These expenses were 
partially offset by decreased management incentive expense and deferred compensation expense. 

Interest expense decreased 10.0% to $2,408,000 in 2007 from $2,676,000 in 2006.  The decrease was primarily due to 
reduced borrowings. 

INCOME TAXES 

The  Company’s  worldwide  effective  income  tax  rates  were  17.0%,  158.3%,  and  32.0%  in  2008,  2007  and  2006, 
respectively.  The 2008 tax rate decreased as compared to 2007 mainly due to the impact of tax-free foreign income. 

As of January 31, 2009, the Company had undistributed earnings of certain foreign subsidiaries for which deferred taxes 
have not been provided.  The Company intends and has the ability to reinvest these earnings for the foreseeable future 
outside the U.S.  If these amounts were distributed to the U.S., in the form of dividends or otherwise, the Company would 
be subject to additional U.S. income taxes.  Determination of the amount of unrecognized deferred income tax liabilities 
on these earnings is not practicable because such liability, if any, is dependent on circumstances existing if and when 
remittance occurs. 

During the fourth quarter of 2007, management determined that all of its foreign net operating loss (“NOL”) carryovers 
and most of its state NOL carryovers generated through January 31, 2008 were no longer more likely than not realizable.  
Additional tax expense of $583,000 or 114.2% of the 2007 rate was recorded to establish a valuation allowance against 
those deferred tax assets. 

A reconciliation of the effective income tax rate to the U.S. Statutory tax rate is as follows:

LIQUIDITY AND CAPITAL RESOURCES 

Cash and cash equivalents as of January 31, 2009 were $2,735,000 as compared to $2,665,000 at January 31, 2008.  The 
Company used $2,165,000 from operations in 2008.  Exercise of stock options resulted in proceeds of $83,000 in 2008. 

Net sales in 2008 increased $63,579,000 or 26.5% compared to 2007 net sales.  The higher sales contributed to the 
increased balances in trade accounts receivable, inventories, and trade accounts payable.  Compared to January 31, 2008, 
trade receivables increased by $21,131,000 primarily due to the piping systems business, of which $14,126,000 was in the 
U.A.E and $6,234,000 was in the HVAC business.  Inventories increased by $8,297,000 in 2008 primarily due to 
increased raw material requirements for scheduled production.  Total inventory increased in the U.A.E. by $5,603,000.

Prepaid and other current assets increased $5,910,000 in 2008 primarily due to the India pipeline project.  Customer 
deposits increased $4,121,000 from January 31, 2008, of these deposits, $5,850,000 related to the piping systems business 
for orders for which the product is expected to be delivered in the first half of 2009 offset by a decrease in the filtration 
products business.  At January 31, 2009, the filtration products business had customer deposits of $1,781,000 for orders 
for which the product is expected to ship in late 2009 and in 2010.

Net cash used in 2008 investing activities was $18,167,000 mainly comprised of capital expenditures which increased to 
$18,464,000 from $5,763,000 in 2007.  The filtration products business facility in Cicero, Illinois relocated its operations 
in the summer of 2008 to a building purchased for $6,400,000 in Bolingbrook, Illinois in March 2008.  Improvements and 
modifications were an additional $3,159,000.  In 2008, the piping systems business opened a facility located in Mundra, 
India with a cost of $5,066,000 for the leasehold improvements and equipment.  Other capital expenditures primarily 
related to machinery and equipment, building and leasehold improvements, and computer hardware and software 
purchases. 

The Company estimates that capital expenditures for 2009 will be approximately $5,500,000, of which the Company may 
finance capital expenditures through real estate mortgages, equipment financing loans, internally generated funds and its 
revolving line of credit. 

Debt totaled $54,883,000, an increase of $20,643,000 since the beginning of 2008.  Net cash inflows from financing 
activity were $130,668,000, primarily to support higher working capital investments.  Stock option activity resulted in 
$374,000 of total cash flow, which included $457,000 tax expense from stock options exercised in addition to stock option 
proceeds of $83,000.

Notes to Contractual Obligations Table 

(1) Interest obligations exclude floating rate interest on debt payable under the domestic revolving line of credit.  

Based on the amount of such debt at January 31, 2009, and the weighted average interest rates on that debt at that 
date (4.94%), such interest was being incurred at an annual rate of approximately $1,173,300. 

(2) Scheduled maturities, including interest. 
(3) Term loan obligations exclude floating rate interest on Term Loan with a January 31, 2009 balance of $2,357,000.  
Based on the amount of such debt as of January 31, 2009, and the weighted average interest rates on that debt at 
that date (5.33%), such interest was being incurred at an annual rate of approximately $125,600. 

(4) Minimum contractual amounts, assuming no changes in variable expenses. 
(5) Includes expected employer contributions for fiscal year ending January 31, 2010 and estimated future benefit 

payments reflecting expected future service. 

(6) Non-qualified deferred compensation plan – The Company has deferred compensation agreements with key 

employees.  Vesting is based on years of service.  Life insurance contracts have been purchased which may be 

20 

 
 
 
 
 
 
 
 
 
used to fund the Company’s obligation under these agreements.  Payment estimates have been included, that the 
third party administrator calculates in May. 

(7) Refer to the Proxy statement for a description of compensation plans for Named Executive Officers. 
(8) Refer to Note 7 – Income Taxes in the Notes to Consolidated Financial Statements for a description of the FIN 48 

obligations.

Other long term liabilities of $4,609,000 were composed primarily of deferred compensation and accrued pension cost. 

The Company’s working capital was $57,984,000 at January 31, 2009 compared to $39,544,000 at January 31, 2008.  
This increase was due to the increase in accounts receivable and inventories partially offset by the increase in accounts 
payable, accrued management incentive and customer deposits. 

The Company’s current ratio increased to 1.8 to 1 at January 31, 2009 from 1.7 to 1.0 at January 31, 2008.  Debt to total 
capitalization at January 31, 2009 increased to 46.1% from 36.4% at January 31, 2008. 

Financing

At January 31, 2009, the Company was in compliance with covenants under the Loan Agreement as defined below. 

On July 11, 2002, the Company entered into a secured loan and security agreement with a financial institution ("Loan 
Agreement").  The Loan Agreement was amended and restated on December 15, 2006.  Under the terms of the Loan 
Agreement, which matures on November 13, 2010, the Company can borrow up to $38,000,000, subject to borrowing 
base and other requirements, under a revolving line of credit.  The Loan Agreement covenants restrict debt, liens, and 
investments, do not permit payment of dividends, and require attainment of certain levels of profitability and cash flows.  
Interest rates generally are based on options selected by the Company as follows:  (a) a margin in effect plus a prime rate; 
or (b) a margin in effect plus the LIBOR rate for the corresponding interest period.  At January 31, 2009, the prime rate 
was 3.25%, and the margins added to the prime rate and the LIBOR rate, which are determined each quarter based on the 
applicable financial statement ratio, were 0.25 and 2.25 percentage points, respectively.  Monthly interest payments were 
made.  The average interest rate for the year ending January 31, 2009 was 4.94%.  As of January 31, 2009, the Company 
had borrowed $23,761,900 and had $50,300 available to it under the revolving line of credit.  In addition, $1,232,400 of 
availability was used under the Loan Agreement primarily to support letters of credit to guarantee amounts committed for 
inventory purchases.  The Loan Agreement provides that all payments by the Company's customers are deposited in a 
bank account from which all funds may only be used to pay the debt under the Loan Agreement.  At January 31, 2009, the 
amount of restricted cash was $220,400.  Cash required for operations is provided by draw-downs on the line of credit. 

The Company also has short-term credit arrangements used by its Denmark and U.A.E. subsidiaries.  These credit 
arrangements are generally in the form of overdraft facilities at rates competitive in the countries in which the Company 
operates.  At January 31, 2009, borrowings under these credit arrangements totaled $11,957,000; an additional $2,835,000 
remained unused. 

On March 4, 2008, the Company borrowed $5,440,000 under a mortgage note secured by the filtration products’ 
manufacturing facility located in Bolingbrook, Illinois.  The 25 year mortgage resets its interest rate every five years 
based on a published index.  The initial interest rate is 6.54% during the first five years with monthly payments of $36,867 
for both principal and interest. 

CRITICAL ACCOUNTING ESTIMATES AND POLICIES 

Revenue recognition:  The Company recognizes revenues including shipping and handling charges billed to customers, 
when all the following criteria are met:  (i) persuasive evidence of an arrangement exists, (ii) the seller’s price to the buyer
is fixed or determinable, and (iii) collectability is reasonably assured.  All subsidiaries of the Company, except as noted 
below, recognize revenues upon shipment or delivery of goods or services when title and risk of loss pass to customers.

Percentage of completion method revenue recognition:  All divisions recognize revenues under the above stated revenue 
recognition policy except for sizable complex contracts that require periodic recognition of income.  For these contracts,  

21 

the Company uses the “percentage of completion” accounting method.  Under this approach, income is recognized in each 
reporting period based on the status of the uncompleted contracts and the current estimates of costs to complete.  The 
choice of accounting method is made at the time the contract is received based on the expected length and complexity of 
the project.  The percentage of completion is determined by the relationship of costs incurred to the total estimated costs 
of the contract.  Provisions are made for estimated losses on uncompleted contracts in the period in which such losses are 
determined.  Changes in job performance, job conditions, and estimated profitability, including those arising from contract 
penalty provisions and final contract settlements, may result in revisions to costs and income.  Such revisions are 
recognized in the period in which they are determined.  Claims for additional compensation due the Company are 
recognized in contract revenues when realization is probable and the amount can be reliably estimated. 

Inventories:  Inventories are stated at the lower of cost or market.  Cost is determined using the first-in, first-out method 
for substantially all inventories. 

Assessment of Potential Impairments of Goodwill and Intangible Assets:  The Company incurred a fourth quarter and 
full year 2008 noncash charge related to the impairment of goodwill of $2,788,000. 

In accordance with SFAS142, during the first quarter each year, the Company reviews the carrying value of goodwill.  
The evaluation of impairment involved comparing the current fair value of the business to the carrying value.  The 
Company used a discounted cash flow model to determine the current fair value of its reporting units.  A number of 
significant assumptions and estimates were involved in the application of the model to forecast operating cash flows, 
including markets and market share, sales volumes and prices, costs to produce and working capital changes.  
Management considered historical experience and all available information at the time the fair values of its reporting units 
were estimated.  However, actual fair values that could be realized in a transaction may differ from those used to evaluate 
the impairment of goodwill. 

The recently completed goodwill impairment assessment followed the fourth quarter 2008 worsening of economic 
conditions.  These conditions impacted both the risks considered and the calculations made.  The assessment considered 
uncertainty about current economic market conditions in the U.S. and globally that may pose risks to the Company’s 
customer demand.  Customers may postpone spending for capital improvement and maintenance projects in response to 
tighter credit markets or negative financial news.  The distressed financial markets caused the discount rates used in 
calculating the present value of estimated future cash flows to be higher than a year ago.  These conditions were reflected 
in the Company’s goodwill impairment assessment. 

As a result, the estimated future cash flows of the filtration products business (whose goodwill was $1,688,000) and the 
industrial process cooling equipment business (whose goodwill was $1,100,000) were both lower than when goodwill 
impairment testing was done a year ago.  All of the Company’s goodwill was deemed impaired and was written off with a 
noncash impairment charge.

Income Tax Provision: Deferred income taxes have been provided for temporary differences arising from differences in 
basis of assets and liabilities for tax and financial reporting purposes.  Deferred income taxes on temporary differences 
have been recorded at the current tax rate.  The Company assessed its deferred tax assets for realizability at each reporting 
period. 

Recently Adopted Accounting Standards: In December 2008, the Financial Accounting Standards Board (“FASB”) 
issued FSP 132(R)-1, “Employers’ Disclosures about Postretirement Benefit Plan Assets” (FSP 132(R)-1).  FSP 132(R)-1 
requires additional disclosures for plan assets of defined benefit pension or other postretirement plans.  The required 
disclosures include a description of the investment policies and strategies, the fair value of each major category of plan 
assets, the inputs and valuation techniques used to measure the fair value of plan assets, the effect of fair value 
measurements using significant unobservable inputs on changes in plan assets, and the significant concentrations of risk 
within plan assets.  FSP 132(R)-1 does not change the accounting treatment for postretirement benefit plans.  FSP 132(R)-
1 is effective for the Company for fiscal year 2009.(cid:3)

In September 2006, the FASB issued SFAS 157, “Fair Value Measurements”, which defines fair value, establishes a 
framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value 
measurements.  SFAS 157 does not require any new fair value measurements, but provides guidance on how to measure  

22 

fair value by providing a fair value hierarchy used to classify the source of the information.  This statement was effective 
for fiscal years beginning after November 15, 2007.  On February 14, 2008, the FASB issued FSP FAS No. 157-1 
“Application of FASB Statement No. 157 to FASB Statement 13 and Other Accounting Pronouncements That Address 
Fair Value Measurements for Purposes of Lease Classification or Measurement Under Statement 13” (SFAS 157-1) that 
amends SFAS 157 to exclude its application for purposes of lease classification or measurement under SFAS 13.  On 
February 12, 2008, the FASB issued Staff Position Financial Accounting Standard (FSP FAS) No. 157-2 “Effective Date 
of FASB Statement No. 157” (FSP 157-2) that amends SFAS 157 to delay the effective date for all non-financial assets 
and non-financial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a 
recurring basis to fiscal years beginning after November 15, 2008.  The Company adopted the required provisions of 
SFAS 157-1 effective January 1, 2008 and there was no material effect on its consolidated financial statements.  The 
Company has adopted FSP 157-2 to delay the adoption effects related to non-financial assets and does not anticipate there 
will be a material effect on its consolidated financial statements.  In October 2008, the FASB issued FSP 157-3, 
“Determining the Fair Value of a Financial Asset in a Market That Is Not Active.”  The FSP was effective upon issuance, 
including periods for which financial statements have not been issued.  The FSP clarified the application of SFAS 157 in 
an inactive market and provided an illustrative example to demonstrate how the fair value of a financial asset is 
determined when the market for that financial asset is inactive.  The adoption of this FSP FAS 157-3 did not have a 
material impact on the Company’s consolidated financial statements. 

In April 2008, the FASB issued FASB Staff Position No. FAS 142-3, Determination of the Useful Life of Intangible 
Assets (“FSP No. FAS 142-3”).  FSP No. FAS 142-3 requires companies estimating the useful life of a recognized 
intangible asset to consider their historical experience in renewing or extending similar arrangements or, in the absence of 
historical experience, to consider assumptions that market participants would use about renewal or extension as adjusted 
for SFAS 142’s, Goodwill and Other Intangible Assets, entity-specific factors.  FSP No. FAS 142-3 will be effective for 
fiscal years beginning after December 15, 2008.  The Company is currently evaluating the potential impact of adoption of 
FSP No. FAS 142-3 on its consolidated financial statements.  However, the Company does not expect the adoption of FSP 
No. FAS 142-3 to have a material effect on its consolidated financial statements.

Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not 
require adoption until a future date are not expected to have a material impact on the consolidated financial statements 
upon adoption. 

Item 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

The Company is subject to market risk associated with changes in foreign currency exchange rates, interest rates and 
commodity prices.  Foreign currency exchange rate risk is mitigated through maintenance of local production facilities in 
the markets served, often (though not always) invoicing customers in the same currency as the source of the products and 
use of foreign currency denominated debt in Denmark, U.A.E. and South Africa.  At times the Company has attempted to 
mitigate its interest rate risk by maintaining a balance of fixed-rate long-term debt and floating-rate debt. 

A hypothetical ten percent change in market interest rates over the next year would increase or decrease interest on the 
Company's floating rate debt instruments by approximately $78,400. 

Commodity price risk is the possibility of higher or lower costs due to changes in the prices of commodities, such as 
ferrous alloys which the Company uses in the production of piping systems.  The Company attempts to mitigate such risks 
by obtaining price commitments from its commodity suppliers and, when it appears appropriate, purchasing quantities in 
advance of likely price increases.

Item 9A.  CONTROLS AND PROCEDURES 

The Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the company’s disclosure 
controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as 
amended) as of January 31, 2009.  Based on that evaluation, the Chief Executive Officer and Chief Financial Officer 
concluded that the Company’s disclosure controls and procedures were effective as of as of January 31, 2009 to ensure 
that information required to be disclosed in the reports that are filed or submitted under the Securities Exchange Act of 
1934 is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms and 
is accumulated and communicated to the issuer’s management, including the principal executive and financial officers, to 
allow timely decisions regarding required disclosure. 

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 such term is defined in Rule 13a-15(f) 
under the Exchange Act.  As required by Rule 13a-15(c) under the Exchange Act, MFRI’s management carried out an 
evaluation, with the participation of the Chief Executive Officer and Chief Financial Officer, of the effectiveness of its 
internal control over financial reporting as of the end of the last fiscal year.  The framework on which such evaluation was 
based is contained in the report entitled “Internal Control—Integrated Framework” issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (the “COSO Report”). 

The Company’s system of 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.  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. 

Based on its assessment, management has concluded that the Company has maintained effective internal control over 
financial reporting as of January 31, 2009, based on criteria in the COSO Report. 

Change in Internal Controls:  There was a material weakness in internal control described in Item 9A of the Company’s 
January 31, 2008 10-K filed on April 30, 2008.  The Company’s processes, procedures and controls related to the 
preparation and review of the quarterly and annual income tax provisions were not deemed effective at October 31, 2007 
and January 31, 2008 to ensure that amounts related to the income tax provisions were accurate.  This material weakness 
resulted in an accounting error, which did not affect the Company's sales, operating expenses, or cash flow.  However, the 
error did result in the understatement of income taxes, and overstatement of current assets, total assets, and net income for 
the interim fiscal period reported at October 31, 2007. 

Other than the material weakness noted above, there has been no change in internal control over financial reporting that 
occurred during the last fiscal year that has materially affected, or is reasonably likely to materially affect, internal control
over financial reporting except as discussed below. 

Remediation Plan for Material Weaknesses in Internal Control over Financial Reporting: As noted above, there was a 
material weakness in internal control described in Item 9A of the Company’s January 31, 2008 10-K filed on April 30, 
2008.  Beginning in 2005, the Company engaged a national public accounting, tax and business consulting firm with 
affiliates worldwide (the “Tax Advisor”) to assist the Company with calculation and  review of its quarterly and annual 
income tax provisions and with its income tax compliance.  To avoid recurrence of an error such as the one described 
above, the Company and Tax Advisor have changed the senior technical resources assigned to the engagement, 
implemented tax software, improved income tax accounting documentation, and adjusted the timing of quarterly and 
annual income tax accounting work. 

24 

The actions described above have resulted in strengthened internal controls over financial reporting relating to accounting 
for income taxes and have fully remediated the related material weakness that was identified as of January 31, 2008.

Report of Independent Registered Public Accounting Firm  

Board of Directors and Stockholders 
MFRI, Inc. and Subsidiaries 

We have audited MFRI, Inc. (a Delaware corporation) and Subsidiaries’ (the “Company”) internal control over financial 
reporting as of January 31, 2009, based on criteria established in Internal Control – Integrated Framework issued by the 
Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).  The Company’s management is 
responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of 
internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over 
Financial Reporting appearing under Item 9A.  Our responsibility is to express an opinion on the Company’s internal 
control over financial reporting based on our audit. 

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

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

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

In our opinion, the Company maintained in all material respects effective internal control over financial reporting as of 
January 31, 2009, based on the criteria established in Internal Control-Integrated Framework issued by COSO. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), the consolidated balance sheets of the Company as of January 31, 2009 and 2008, and the related consolidated 
statements of operations, stockholders’ equity, comprehensive income (loss) and cash flows for each of the three years in 
the period ended January 31, 2009, and our report dated April 15, 2009, expressed an unqualified opinion on those 
financial statements.

Report of Independent Registered Public Accounting Firm 

Board of Directors and Stockholders 
MFRI, Inc. and Subsidiaries  

We have audited the accompanying consolidated balance sheets of MFRI, Inc. (a Delaware corporation) and Subsidiaries 
(the “Company”) as of January 31, 2009 and 2008, and the related consolidated statements of operations, stockholders’ 
equity, comprehensive income (loss) and cash flows for each of the three years in the period ended January 31, 2009.  Our 
audits of the basic financial statements included the financial statement schedule listed in the index appearing under Item 
15(a)(2).  These financial statements and financial statement schedule are the responsibility of the Company’s 
management.  Our responsibility is to express an opinion on these financial statements and financial statement schedule 
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 above present fairly, in all material respects, the financial
position of MFRI, Inc. and Subsidiaries as of January 31, 2009 and 2008, and the results of their operations and their cash 
flows for each of the three years in the period ended January 31, 2009, in conformity with accounting principles generally 
accepted in the United States of America.  Also in our opinion, the related financial statement schedule, when considered 
in relation to the basic financial statements taken as a whole, presents fairly, in all material respects, the information set 
forth therein. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), MFRI, Inc. and Subsidiaries’ internal control over financial reporting as of January 31, 2009, based on criteria 
established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (COSO) and our report dated April 15, 2009, expressed an unqualified opinion on the effective 
operation of internal control over financial reporting.

MFRI, INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
YEARS ENDED January 31, 2009, 2008 and 2007 
(Tabular dollars in thousands, except per share amounts) 

Note 1 - Description of the Business and Segment Information 

MFRI, Inc. ("MFRI", the “Company”, or the “Registrant”) was incorporated on October 12, 1993.  MFRI is engaged in 
the manufacture and sale of products in three distinct business segments:  piping systems, filtration products and industrial 
process cooling equipment. 

Fiscal Year:  The Company’s fiscal year ends on January 31.  Years and balances described as 2008, 2007 and 2006 are 
the fiscal years ended January 31, 2009, 2008 and 2007, respectively. 

Nature of Business:  The piping systems business engineers, designs, manufactures and sells specialty piping systems and 
leak detection and location systems.  This segment’s specialty piping systems include (i) industrial and secondary 
containment piping systems for transporting chemicals, waste streams and petroleum liquids, (ii) insulated and jacketed 
district heating and cooling piping systems for efficient energy distribution to multiple locations from central energy 
plants, and (iii) oil and gas gathering flow lines and long lines for oil and mineral transportation.  The piping systems 
business’s leak detection and location systems are sold as part of many of its piping systems products, and on a stand-
alone basis, to monitor areas where fluid intrusion may contaminate the environment, endanger personal safety, cause a 
fire hazard, impair essential services or damage equipment or property.  The filtration products business manufactures and 
sells a wide variety of filter elements for use in industrial air filtration systems and particulate collection systems.  Air 
filtration systems are used in a wide variety of industries to limit particulate emissions, primarily to comply with 
environmental regulations.  The filtration products business markets air filtration related products and accessories, and 
provides maintenance services, consisting primarily of dust collector inspection, filter cleaning and filter replacement.
The industrial process cooling equipment business engineers, designs, manufactures and sells industrial process cooling 
equipment, including chillers, cooling towers, plant circulating systems, and related accessories for use in industrial 
process applications.  During the fourth quarter 2006, the Company created a new subsidiary that is not sufficiently large 
enough to constitute a reportable segment, which engages in the installation of HVAC systems.  The Company’s products 
are sold both within the U.S. and internationally. 

MFRI’s reportable segments are strategic businesses that offer different products and services.  Each is managed 
separately based on fundamental operating differences.  Each strategic business was acquired as a unit and management at 
the time of acquisition was retained.  The Company evaluates performance based on gross profit and income or loss from 
operations.

Note 2 - Significant Accounting Policies 

Reclassifications:  Reclassifications were made to prior-year financial statements to conform to the current-year 
presentations.

Use of Estimates:  The preparation of financial statements in conformity with generally accepted U.S. accounting 
principles requires management to make estimates and assumptions that affect the reported amounts of assets and 
liabilities and disclosures 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. 

Revenue Recognition:  The Company recognizes revenues including shipping and handling charges billed to customers, 
when all the following criteria are met:  (i) persuasive evidence of an arrangement exists, (ii) the seller’s price to the buyer
is fixed or determinable, and (iii) collectability is reasonably assured.  All subsidiaries of the Company, except as noted 
below, recognize revenues upon shipment or delivery of goods or services when title and risk of loss pass to customers.

Percentage of Completion Revenue Recognition:  All divisions recognize revenues under the above stated revenue 
recognition policy except for sizable complex contracts - that require periodic recognition of income.  For these contracts, 
the Company uses "percentage of completion" accounting method.  Under this approach, income is recognized in each 
reporting period based on the status of the uncompleted contracts and the current estimates of costs to complete.  The 
choice of accounting method is made at the time the contract is received based on the expected length and complexity of 
the project.  The percentage of completion is determined by the relationship of costs incurred to the total estimated costs 
of the contract.  Provisions are made for estimated losses on uncompleted contracts in the period in which such losses are 
determined.  Changes in job performance, job conditions, and estimated profitability, including those arising from contract 
penalty provisions and final contract settlements, may result in revisions to costs and income.  Such revisions are 
recognized in the period in which they are determined.  Claims for additional compensation due the Company are 
recognized in contract revenues when realization is probable and the amount can be reliably estimated.

Shipping and Handling:  Shipping and handling costs are included in cost of goods sold, and the amounts invoiced to 
customers relating to shipping and handling are included in net sales. 

Operating Cycle: The length of the piping systems business’s contracts vary, but are typically less than one year.  The 
Company includes in current assets and liabilities amounts realizable and payable in the normal course of contract 
completion unless completion of such contracts extends significantly beyond one year.  The Company’s other businesses 
do not have an operating cycle beyond one year. 

Principles of Consolidation:  The consolidated financial statements include the accounts of the Company and its domestic 
and foreign subsidiaries, all of which are wholly owned.  All significant intercompany balances and transactions have 
been eliminated. 

Translation of Foreign Currency:  Assets and liabilities of consolidated foreign subsidiaries are translated into U.S. 
dollars at exchange rates in effect at year-end.  Revenues and expenses are translated at average exchange rates prevailing 
during the year.  Gains or losses on foreign currency transactions and the related tax effects are reflected in net income.  
The resulting translation adjustments are included in stockholders’ equity as part of accumulated comprehensive income. 

Contingencies:  The Company is subject to various legal proceedings and claims that arise in the ordinary course of 
business, including those involving environmental, tax, product liability and general liability claims.  The Company 
accrues for such liabilities when it is probable that future costs will be incurred and such costs can be reasonably 
estimated.  Such accruals are based on developments to date, the Company’s estimates of the outcomes of these matters, 
and its experience in contesting, litigating and settling other similar matters.  The Company does not currently anticipate 
the amount of any ultimate liability with respect to these matters will materially affect the Company’s financial position, 
liquidity or future operations. 

Cash and Cash Equivalents:  All highly liquid investments with a maturity of three months or less when purchased are 
considered to be cash equivalents.  The balance is primarily cash and cash equivalents at the foreign subsidiaries.  The 
Company has not experienced any losses as a result of its cash concentration.  Consequently, no significant concentration 
of credit risk is considered to exist.  Accounts payable included drafts payable of $7,349,000 and $7,157,000 as of January 
31, 2009, and 2008, respectively. 

Restricted Cash:  The Loan Agreement requires that all payments by the Company’s customers are deposited in a bank 
account from which all funds may only be used to pay the debt under the Loan Agreement. 

Accounts Receivable Collection:  The majority of the Company’s accounts receivable are due from geographically 
dispersed contractors and manufacturing companies.  Credit is extended based on an evaluation of a customer’s financial 
condition, including the availability of credit insurance.  Generally, collateral is not required.  Accounts receivable are due
within various time periods specified in the terms applicable to the specific customer and are stated at amounts due from 
customers net of an allowance for claims and doubtful accounts.  The allowance for doubtful accounts was calculated 
using a percentage of sales method based upon collection history and an estimate of uncollectible accounts.  Management 
may exercise its judgment in adjusting the provision as a consequence of known items, such as current economic factors 
and credit trends.  Accounts receivable adjustments are recorded against the allowance for doubtful accounts. 

Concentration of Credit Risk: The Company has a broad customer base doing business in all regions of the U.S. as well 
as other areas in the world.  The Company maintains foreign credit insurance covering selected foreign sales not secured 
by letters of credit or guarantees from parent companies in the U.S.  This expense is included in general and 
administrative expense in the Consolidated Statements of Operations.  In the fiscal year ended January 31, 2009 and 2008, 
no customer accounted for 10% or more of net sales. 

Other Comprehensive Income (Loss):  Other comprehensive income (loss) is defined as the change in equity resulting 
from transactions from non-owner sources.  Other comprehensive income (loss) consisted of the following: minimum 
pension liability, foreign currency translation, unrealized gain on marketable securities and interest rate swap. 

Pension Plan:  The Winchester facility has a defined benefit plan covering its hourly employees.  The benefits are based 
on fixed amounts multiplied by years of service of retired participants.  The Company engages outside actuaries to  

35 

calculate its obligations and costs.  The funding policy is to contribute such amounts as are necessary to provide for 
benefits attributed to service to date and those expected to be earned in the future.  The amounts contributed to the plan 
are sufficient to meet the minimum funding requirements set forth in the Employee Retirement Income Security Act of 
1974. 

Inventories:  Inventories are stated at the lower of cost or market.  Cost is determined using the first-in, first-out method 
for substantially all inventories.  Inventories consist of the following: 

Raw materials 
Work in process 
Finished goods 
Subtotal 
Less allowances

Long-Lived Assets:  Property, plant and equipment are stated at cost.  Interest is capitalized in connection with the 
construction of facilities and amortized over the asset’s estimated useful life.  Interest of $152,000 was capitalized during 
2008.  Long-lived assets are reviewed for possible impairment whenever events indicate that the carrying amount of such 
assets may not be recoverable.  If such a review indicates impairment, the carrying amount of such assets is reduced to an 
estimated fair value. 

Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from 
three to 30 years.  Leasehold improvements are depreciated over the remaining life of the lease or its useful life whichever 
is shorter.  Amortization of assets under capital leases is included in depreciation and amortization. 

The Company’s investment in property, plant and equipment is summarized below: 

Land, buildings and improvements 
Machinery and equipment 
Furniture, office equipment and computer systems

Assessment of Potential Impairments of Goodwill and Intangible Assets:  The Company incurred a fourth quarter and 
full year 2008 noncash charge of $2,788,000 related to the impairment of goodwill. 

In accordance with Statement of Financial Accounting Standards (“SFAS”) No. 142, “Goodwill and Other Intangible 
Assets,” during the first quarter each year the Company reviews the carrying value of goodwill.  The evaluation of 
impairment involved comparing the current fair value of the business to the carrying value.  The Company used a 
discounted cash flow model to determine the current fair value of its reporting units.  A number of significant assumptions 
and estimates were involved in the application of the model to forecast operating cash flows, including markets and 
market share, sales volumes and prices, costs to produce and working capital changes.  Management considered historical 
experience and all available information at the time the fair values of its reporting units were estimated.  However, actual 
fair values that could be realized in a transaction may differ from those used to evaluate the impairment of goodwill. 

The recently completed goodwill impairment assessment followed the fourth quarter 2008 worsening of economic 
conditions.  These conditions impacted both the risks considered and the calculations made.  The assessment considered 
uncertainty about current economic market conditions in the U.S. and globally that may pose risks to the Company’s 
customer demand.  Customers may postpone spending for capital improvement and maintenance projects in response to 
tighter credit markets or negative financial news.  The distressed financial markets caused the discount rates used in 
calculating the present value of estimated future cash flows to be higher than a year ago.  These conditions were reflected 
in the Company’s goodwill impairment assessment.

As a result, the estimated future cash flows of the filtration products business (whose goodwill was $1,688,000) and the 
industrial process cooling equipment business (whose goodwill was $1,100,000) were both lower than when goodwill 
impairment testing was done a year ago.  All of the Company’s goodwill was deemed impaired and was written off with a 
noncash impairment charge.

Other intangible assets with definite lives:  The Company owns several patents covering the features of its piping and 
electronic leak detection systems.  The patents are not material either individually or in the aggregate to the overall 
business because the Company believes sales in the business would not be materially reduced if patent protection were not 
available.  Patents are capitalized and amortized on a straight-line basis over a period not to exceed the legal lives of the 
patents.  Gross patents were $2,494,000 and 2,447,000 as of January 31, 2009, and 2008.  Accumulated amortization was 
$2,202,000 and $2,098,000 as of January 31, 2009, and 2008, respectively.  Future amortizations over the next five years 
ending January 31 will be $107,000 in 2010, $87,000 in 2011, $35,000 in 2012, $35,000 in 2013, $28,000 in 2014. 

Investment in Joint Venture:  In April 2002, the piping system business and two unrelated companies formed an equally 
owned joint venture to more efficiently market their complementary thermal insulation products and systems for use in 
undersea pipeline flow assurance projects worldwide.  On June 28, 2007, the piping system business loaned the joint 
venture $100,000.  The loan and interest were paid in 2008. The Company accounts for its joint venture investment 
using the equity method.

Research:  Research and development expenses consist of materials, salaries and related expenses of certain engineering 
personnel, and outside services related to product development projects.  Research and development costs are expensed as 
incurred.  Research and development expense was $2,517,000 in 2008, $4,994,000 in 2007, and $4,722,000 in 2006.

Financial Instruments:  Gains and losses on hedges of existing assets, or liabilities are marked-to-market and the result is 
included within accumulated other comprehensive income in the consolidated financial statements.  Gains and losses on 
financial instruments that hedge firm future commitments are deferred until the underlying transactions are recognized or 
recorded immediately when the transaction is no longer expected to occur.  Gains or losses on financial instruments that 
do not qualify as hedges under Statement of Financial Accounting Standards No. 133, “Accounting for Derivative 
Instruments and Hedging Activities” are recognized immediately as income or expense. 

Income Tax Provision:  Income taxes are in accordance with Statement of Financial Accounting Standard No. 109, or 
FAS 109, Accounting for Income Taxes, as clarified by FASB Interpretation No. 48, Accounting for Uncertainty in 
Income Taxes (“FIN 48”).  Deferred income taxes have been provided for temporary differences arising from differences 
in basis of assets and liabilities for tax and financial reporting purposes.  Deferred income taxes on temporary differences 
have been recorded at the current tax rate.  The Company assessed its deferred tax assets for realizability at each reporting 
period. 

FIN 48 requires that the Company recognize the financial statement benefit of a tax position only after determining that 
the relevant tax authority would more likely than not sustain the position following an audit.  For tax positions meeting the 
more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater 
than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.  For further 
information see Note 7 – Income Taxes in the Notes to Consolidated Financial Statements. 

Net Income Per Common Share:  Earnings per share (“EPS”) are computed by dividing net income by the weighted 
average number of common shares outstanding (basic) plus all potentially dilutive common shares outstanding during the 
year (diluted).  The computation of diluted EPS for the year ended January 31, 2008 excluded 111 stock options due to the 
loss for the period.

In 2008, a total of 27,650 stock options were exercised.  From February 1, 2009 through March 31, 2009, 450 stock 
options were exercised. 

Stock Options: Stock compensation expense for employee equity awards are recognized ratably over the requisite service 
period of the award.  The Black-Scholes option-pricing model is utilized to estimate the fair value of awards.  
Determining the fair value of stock options using the Black-Scholes model requires judgment, including estimates for (1) 
risk-free interest rate – an estimate based on the yield of zero–coupon treasury securities with a maturity equal to the 
expected life of the option; (2) expected volatility – an estimate based on the historical volatility of the Company’s 
Common Stock; and (3) expected life of the option – an estimate based on historical experience including the effect of 
employee terminations.  If any of these assumptions differ significantly from actual, stock-based compensation expense 
could be impacted. 

Fair Value of Financial Instruments: The carrying values of cash and cash equivalents, accounts receivable and 
accounts payable are reasonable estimates of their fair value due to their short-term nature.  The carrying amount of the 
Company’s short-term debt, revolving line of credit and long term debt approximate fair value because the majority of the 
amounts outstanding accrue interest at variable rates. 

New Accounting Pronouncements: In December 2008, the Financial Accounting Standards Board (“FASB”) issued FSP 
132(R)-1, “Employers’ Disclosures about Postretirement Benefit Plan Assets” (FSP 132(R)-1).  FSP 132(R)-1 requires 
additional disclosures for plan assets of defined benefit pension or other postretirement plans.  The required disclosures 
include a description of the investment policies and strategies, the fair value of each major category of plan assets, the 
inputs and valuation techniques used to measure the fair value of plan assets, the effect of fair value measurements using 
significant unobservable inputs on changes in plan assets, and the significant concentrations of risk within plan assets.
FSP 132(R)-1 does not change the accounting treatment for postretirement benefit plans.  FSP 132(R)-1 is effective for 
the Company for fiscal year 2009. 

In September 2006, the FASB issued SFAS 157, “Fair Value Measurements”, which defines fair value, establishes a 
framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value 
measurements.  SFAS 157 does not require any new fair value measurements, but provides guidance on how to measure 
fair value by providing a fair value hierarchy used to classify the source of the information.  This statement was effective 
for fiscal years beginning after November 15, 2007.  On February 14, 2008, the FASB issued FSP FAS No. 157-1 
“Application of FASB Statement No. 157 to FASB Statement 13 and Other Accounting Pronouncements That Address 
Fair Value Measurements for Purposes of Lease Classification or Measurement Under Statement 13” (SFAS 157-1) that 
amends SFAS 157 to exclude its application for purposes of lease classification or measurement under SFAS 13.  On 
February 12, 2008, the FASB issued Staff Position Financial Accounting Standard (FSP FAS) No. 157-2 “Effective Date 
of FASB Statement No. 157” (FSP 157-2) that amends SFAS 157 to delay the effective date for all non-financial assets 
and non-financial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a 
recurring basis to fiscal years beginning after November 15, 2008.  The Company adopted the required provisions of 
SFAS 157-1 effective January 1, 2008 and there was no material effect on its consolidated financial statements.  The 
Company has adopted FSP 157-2 to delay the adoption effects related to non-financial assets and does not anticipate there 
will be a material effect on its consolidated financial statements.  In October 2008, the FASB issued FSP 157-3, 
“Determining the Fair Value of a Financial Asset in a Market That Is Not Active.”  The FSP was effective upon issuance, 
including periods for which financial statements have not been issued.  The FSP clarified the application of SFAS 157 in

an inactive market and provided an illustrative example to demonstrate how the fair value of a financial asset is 
determined when the market for that financial asset is inactive.  The adoption of this FSP FAS 157-3 did not have a 
material impact on the Company’s consolidated financial statements.(cid:3)

In April 2008, the FASB issued FASB Staff Position No. FAS 142-3, Determination of the Useful Life of Intangible 
Assets (“FSP No. FAS 142-3”).  FSP No. FAS 142-3 requires companies estimating the useful life of a recognized 
intangible asset to consider their historical experience in renewing or extending similar arrangements or, in the absence of 
historical experience, to consider assumptions that market participants would use about renewal or extension as adjusted 
for SFAS 142’s, Goodwill and Other Intangible Assets, entity-specific factors.  FSP No. FAS 142-3 will be effective for 
fiscal years beginning after December 15, 2008.  The Company is currently evaluating the potential impact of adoption of 
FSP No. FAS 142-3 on its consolidated financial statements.  However, the Company does not expect the adoption of FSP 
No. FAS 142-3 to have a material effect on its consolidated financial statements. 

Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not 
require adoption until a future date are not expected to have a material impact on the consolidated financial statements 
upon adoption.

At January 31, 2009, the Company was in compliance with covenants under the Loan Agreement as defined below. 

On July 11, 2002, the Company entered into a secured loan and security agreement with a financial institution ("Loan 
Agreement").  The Loan Agreement was amended and restated on December 15, 2006.  Under the terms of the Loan 
Agreement, which matures on November 13, 2010, the Company can borrow up to $38,000,000, subject to borrowing 
base and other requirements, under a revolving line of credit.  The Loan Agreement covenants restrict debt, liens, and 
investments, do not permit payment of dividends, and require attainment of certain levels of profitability and cash flows.  
Interest rates generally are based on options selected by the Company as follows:  (a) a margin in effect plus a prime rate; 
or (b) a margin in effect plus the LIBOR rate for the corresponding interest period.  At January 31, 2009, the prime rate 
was 3.25%, and the margins added to the prime rate and the LIBOR rate, which are determined each quarter based on the 
applicable financial statement ratio, were 0.25 and 2.25 percentage points, respectively.  Monthly interest payments were 
made.  The average interest rate for the year ending January 31, 2009 was 4.94%. 

The Company has two material debt covenants.  (1) Consolidated EBITDA for the four consecutive fiscal quarters, (but 
excluding any extraordinary gains for such period) plus the amount of any expenses or charges deducted there from for 
the applicable period in connection with the closure and write down of the company’s facility in Cicero, Illinois, provided 
that the aggregate amount of add-backs to EBITDA as a result of any such charges or expenses shall not exceed 
$2,500,000.  The company is required to achieve EBITDA of at least $8,000,000 each fiscal quarter.  (2) Consolidated 
fixed charge coverage at the end of each month is required to be at least 1.0 for the twelve months then ended, unless 
collateral availability exceeds amounts borrowed by at least $6,500,000.  Fixed charge coverage is a fraction whose 
numerator equals EBITDA minus capital expenditures (but excluding capital expenditures separately financed) and minus 
cash income taxes, and the denominator equals cash interest expense and loan principal payments (but excluding principal 
payments of revolving loans).  At January 31, 2009, the Company was in compliance with covenants under the Loan 
Agreement. 

As of January 31, 2009, the Company had borrowed $23,761,900 and had $50,300 available to it under the revolving line 
of credit.  In addition, $1,232,400 of availability was used under the Loan Agreement primarily to support letters of credit 
to guarantee amounts committed for inventory purchases.  The Loan Agreement provides that all payments by the 
Company's customers are deposited in a bank account from which all funds may only be used to pay the debt under the 
Loan Agreement.  At January 31, 2009, the amount of restricted cash was $220,400.  Cash required for operations is 
provided by draw-downs on the line of credit. 

The Company guarantees the subsidiaries’ debt including all foreign debt. 

Mortgages: On March 4, 2008, the Company borrowed $5,440,000 under a mortgage note secured by the filtration

that time.  The loan bears interest at 7.10% with a monthly payment of $23,616 for both principal and interest, and has a 
ten year term. 

On June 1, 1998, the Company obtained a loan in the amount of 4,500,000 DKK (approximately $650,000 U.S. dollars at 
the prevailing exchange rate at the time of the transaction) from a Danish bank to partially finance the acquisition of Boe-
Therm A/S (“Boe-Therm”).  It is secured by the land and building of Boe-Therm, bears interest at 6.48% and has a term 
of twenty years.  Another loan in the amount of 850,000 DKK  (approximately $134,000 U.S. dollars at the prevailing  
exchange rate at the time of the  transaction)  was  obtained  on January 1, 1999 to acquire land and a building,  bears  
interest at 6.1% and has a term of twenty  years.  The interest rates on both the twenty-year loans are guaranteed for the 
first ten years, after which they will be renegotiated based on prevailing market conditions. 

Revolving lines foreign: The Company also has short-term credit arrangements used by its Denmark and U.A.E. 
subsidiaries.  These credit arrangements are generally in the form of overdraft facilities at rates competitive in the 
countries in which the Company operates.  The interest rate at the Denmark subsidiaries was 6.1% at January 31, 2009, 
and the interest rate at the U.A.E subsidiaries was 8.5% at January 31, 2009.  At January 31, 2009, borrowings under these

(approximately $1,765,000 U.S. dollars at the prevailing exchange rate at the time of the transaction) from a Danish bank 
to finance capital expenditures and other expenses.  The loan matures May 2011.  The loan bears interest at a floating rate 
at January 31, 2009 of 5.00% per annum with monthly principal payments of $35,300. 

On August 28, 2007, the Company amended and restated the Term Loan Note to $3,000,000 ("Term Loan").  In March 
2005, the Company’s Loan Agreement was amended to add a term loan.  Interest rates under the Term Loan are based on 
options selected by the Company as follows:  (a) a margin in effect plus a prime rate; or (b) a margin in effect plus the 
LIBOR rate for the corresponding interest period.  At January 31, 2009, the prime rate was 3.25% and the Libor rate was 
0.5%, and the margins added to the prime rate and the LIBOR rate, which are determined each quarter based on the 
applicable financial statement ratio, were 0.50 and 2.5 percentage points, respectively.  The Company is scheduled to pay 
$107,000 of principal on the first days of March, June, September, and December in each year ending on September 30,

with quarterly payments of $9,400 for both principal and interest.

The piping systems business leases manufacturing and warehouse facilities, land, transportation equipment and office 
space under non-cancelable operating leases, which expire beginning 2009 through 2017.  The filtration products business 
leases approximately 67,000 square feet of production and office space under an operating lease, which began in June 
2004 and expires in July 2010.  Management expects that these leases will be renewed or replaced by other leases in the 
normal course of business.

The (deficiency) excess tax benefit related to stock options recorded through equity was ($457,000), $1,466,000, and 
$945,000 in 2008, 2007 and 2006, which did not affect net income in 2008, 2007 and 2006.  The amounts were recorded 
to additional paid-in capital on the consolidated balance sheet and in financing activities on the consolidated statement of 
cash flows.  The deficiency in 2008 related to removing foreign employee stock option grants from the stock 
compensation expense and its associated deferred tax item. 

The 2007 income tax expense included a charge for valuation of the net operating loss (“NOL”) carryforwards.  During 
the fourth quarter of 2007, management determined that all of its foreign NOL carryovers and most of its state NOL 
carryovers were no longer more likely than not realizable.  Additional tax expense of $583,000 was recorded to establish a 
valuation allowance against those deferred tax assets.  Management believes that the remainder of its deferred tax assets, 
which primarily relate to its profitable domestic operations, are more likely than not to be realized. 

The difference between the provision for income taxes and the amount computed by applying the Federal effective rate of 
34% was as follows: 

Tax expense at federal statutory rate 
Foreign rate tax (benefit) expense differential 
Impairment on goodwill 
Valuation allowance for net operating losses * 
State tax expense (benefit), net of federal benefit 
Return to provision adjustments 
Research tax credit 
Other – net 
Total 

* Valuation allowances against foreign and state net operating loss 
benefits:
For current year operating losses 
For prior year operating loss carryovers

The Company has a Federal operating loss carryforwards of $3,448,000 with a recognized tax benefit of $1,272,000 that 
will expire in 2029. 

The deferred tax asset for state operating loss carryforwards of $479,000 relates to amounts that expire at various times 
from 2009 to 2029.  The amount that will expire in 2009 is approximately $10,000.  A valuation allowance has been 
established for approximately $390,000 of this tax asset based upon an assessment that it is more likely than not that 
realization cannot be assured in certain tax jurisdictions. 

The Company has a deferred tax asset for foreign operating loss carryforwards of $550,000 that can be carried forward 
indefinitely.  The Company also has a deferred tax asset for foreign operating loss carryforwards of $597,000 for which a 
100% valuation allowance has been established based upon an assessment that it is more likely than not that realization 
cannot be assured.  The ultimate realization of this tax benefit is dependent upon the generation of sufficient operating 
income in the respective tax jurisdictions.  This benefit can be carried forward indefinitely. 

Components of the deferred income tax asset balances were as follows: 

Research tax credit 
U.S. federal NOL carryover 
Accrued commissions and bonuses 
Foreign NOL carryover 
Other accruals not yet deducted 
Non-qualified deferred compensation

In the first quarter of 2007, the Company adopted FIN 48.  The total amount of unrecognized tax liability as of February 
1, 2007 was approximately $573,700, all of which would impact the effective tax rate if recognized.  A decrease of 
$504,500 was recorded to retained earnings as of February 1, 2007 upon the adoption of FIN 48.  These non-current 
income tax liabilities are recorded in other long-term liabilities in the consolidated balance sheet.  Included in the total 
unrecognized tax liability were estimated accrued interest of $57,300 and penalties of $51,000.  The Company’s policy is 
to include interest and penalties in income tax expense.

The Company is subject to income taxes in the U.S. federal jurisdiction, and various states and foreign jurisdictions.  Tax 
regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require 
significant judgment to apply.  Generally, tax years back to January 31, 2006 are open for federal and state tax purposes.  
In addition, federal and state tax losses generated in years January 31, 2001 through January 31, 2005 are subject to 
adjustment on audit, up the amount of loss claimed in those years. 

The Company’s management periodically estimates the probable tax obligations of the Company using historical 
experience in tax jurisdictions and informed judgments.  There are inherent uncertainties related to the interpretation of 
tax regulations in the jurisdictions in which the Company transacts business.  The judgments and estimates made at a 
point in time may change based on the outcome of tax audits, as well as changes to or further interpretations of 
regulations.  If such changes take place, there is a risk that the tax rate may increase or decrease in any period.  Tax 
accruals for tax liabilities related to potential changes in judgments and estimates for federal, foreign and state tax issues 
are included in current liabilities on the consolidated balance sheet. 

Note 8 - Employee Retirement Plans 

Pension Plan 

The Winchester facility has a defined benefit plan covering its hourly rated employees.  The benefits are based on fixed 
amounts multiplied by years of service of retired participants.  The Company engages outside actuaries to calculate its 
obligations and costs.  The funding policy is to contribute such amounts as are necessary to provide for benefits attributed 
to service to date and those expected to be earned in the future.  The amounts contributed to the plan are sufficient to meet 
the minimum funding requirements set forth in the Employee Retirement Income Security Act of 1974.  The Company 
may contribute additional amounts at its discretion. 

The market related value of plan assets at January 31, 2009 was $3,047,730; 2,866,458 in Vanguard Balanced Index Fund, 
$45,036 in Vanguard REIT Index Fund, $136,149 in Fifth Third Banksafe Trust and $88 accrued income.  The plans hold 
no securities of MFRI, Inc. 100% of the assets are held for benefits under the plan.  The target asset allocation was 95% to 
100% mutual funds.  The investment policy is to invest substantially all funds not needed to pay benefits and investment 
expenses for the year, with target asset allocations of 60% equities (plus or minus 10%) and 40% fixed income (plus or 
minus 10%), diversified across a variety of sub-asset classes and investment styles, following a flexible asset allocation 
approach that will allow the plan to participate in market opportunities as they become available.  At January 31, 2009, 
95.5% of plan assets were held in mutual funds and the remaining 4.5% was in a money market fund.  The expected long-
term rate of return on assets is based on historical long-term rates of equity and fixed income investments and the asset 
mix objective of the funds. 

Investment market conditions in late 2008 resulted in a negative $946,000 actual return on plan assets as presented below, 
which reduced the fair value of plan assets at year end, as is also presented below.  As a result, the actuarially calculated 
contributions as required under the provisions of the Employment Retirement Income Security Act of 1974 and the 
Internal Revenue Code as amended, including the Pension Protection Act of 2006 (PPA) resulted in a contribution of 
$302,000 being made during February 2009, to attain funding targets necessary to avoid PPA restrictions on the plan with 
respect to benefit increases and payments.  While recognizing the 2008 market losses, the Company did not change its 8% 
expected return on plan assets used in determining cost and benefit obligations, the return that the Company has assumed 
during every profitable and unprofitable investment year since 1991.  The plan’s investments are intended to earn long-
term returns to fund long-term obligations, and investment portfolios with asset allocations similar to those of the plan’s 
investment policy have attained such returns over several decades.  The effects of market conditions and investment losses

on the plan’s net periodic benefit and cost amortization of actuarial loss were not material to the Company’s results of 
operations or financial position.  The February 2009 contribution did not materially affect the Company’s liquidity, nor 
are future contributions that may be necessary to maintain funding requirements expected to materially affect the 
Company’s liquidity.  The Company does not expect the decrease in plan assets to have any impact on the Company’s 
future operations. 

The following provides a reconciliation of benefit obligations, plan assets and funded status of the plan:

For 2008, the discount rate was based on a Citigroup yield curve of high quality fixed income investments with cash flows 
matching the plans' expected benefit payments.  The Company determines the expected long-term rate of return on plan 
assets by performing a detailed analysis of historical and expected returns based on the strategic asset allocation approved 
by the Board of Directors and the underlying return fundamentals of each asset class.  The Company’s historical 
experience with the pension fund asset performance is also considered.

401(k) Plan 

The domestic employees of the Company participate in the MFRI, Inc. Employee Savings and Protection Plan, which is 
applicable to all employees except certain employees covered by collective bargaining agreement benefits.  The plan 
allows employee pretax payroll contributions of up to 16% of total compensation.  The Company matches 50% of each 
participant's contribution, up to a maximum of 3% of each participant’s salary. 

Contributions to the 401(k) Plan were $557,100, $608,200, and $385,400 for the years ended January 31, 2009, 2008 and 
2007, respectively.  In 2007, contributions included $133,800 related to forfeiture allocations for prior years.  The 
Company estimates that it will contribute $490,000 for the year ending January 31, 2010. 

Deferred Compensation Plans 

The Company has deferred compensation agreements with key employees.  Vesting is based on years of service.  Life 
insurance contracts have been purchased which may be used to fund the Company’s obligation under these agreements.  
The deferred compensation plan was affected by the market value of the underlying investments.  Since the underlying 
investment declined in 2008, the Company’s deferred compensation expense and liability to the employees in the plan 
decreased. 

Note 9 - Stock Options 

Under the 2004 Stock Option Plan (“Option Plan”), 250,000 shares of common stock are reserved for issuance to 
employees of the Company and its affiliates as well as certain advisors and consultants to the Company.  In addition, 
under the Option Plan, the number of shares that may be issued shall be increased by an additional two percent of the 
aggregate number of shares of Common Stock outstanding as of the last day of the most recently completed fiscal year of 
the Company, beginning January 31, 2005.  Option exercise prices will be no less than fair market value for the common 
stock on the date of grant.  The options granted under the Option Plan may be either non-qualified options or incentive 
options. 

Pursuant to the 2001 Independent Directors’ Stock Option Plan, an option to purchase 10,000 shares of common stock is 
granted automatically to each director who is not an employee of the Company (an “Independent Director”) on the date 
the individual is first elected as an Independent Director.  An option to purchase 1,000 shares was granted to each 
Independent Director acting on December 31, 2001, and options to purchase 1,000 shares are granted to each Independent 
Director upon each date such Independent Director is re-elected as an Independent Director, commencing with the 
Company’s annual meeting for the year 2002.

Such options vest ratably over four years and are exercisable for up to ten years from the date of grant.  To cover the 
exercise of vested options, the Company generally issues new shares from its authorized but unissued share pool.  The 
Company calculates stock compensation expense based on the grant date fair value of the option and recognizes expense 
on a straight-line basis over the four-year vesting period of the option. 

The fair value of each option award was estimated on the date of grant using the Black-Scholes Merton option-pricing 
model that used the assumptions noted in the following table.  The principal variable assumptions utilized in valuing 
options and the methodology for estimating such model inputs include:  

1.

risk-free interest rate - an estimate based on the “Market yield on U.S. Treasury securities at the rate for the 
period described in assumption 3 below, quoted on investment basis" for the end of week closest to the stock 
option grant date, from the Federal Reserve web site;  

2. expected volatility - an estimate based on the historical volatility of MFRI Common Stock’s weekly closing 

3.

stock price for the period 1/1/93 to the date of grant; and  
 expected life of the option - an estimate based on historical experience including the effect of employee 
terminations. 

1.   Risk-free interest rate 
2.   Expected volatility 
3.   Expected life in years 
4.   Dividend yield

The weighted average fair value of options granted during 2008 (net of options surrendered), 2007 and 2006 are estimated 
at $16.41, $14.54 and $5.99, per share, respectively, on the date of grant.  The total intrinsic value of options exercised 
during the years ended January 31, 2008, 2007 and 2006 were $125,000, $3,837,000 and $2,624,000, respectively.

As of January 31, 2009, there was $2,334,400 of total unrecognized compensation cost related to nonvested share-based 
compensation arrangements granted under the Plans.  That cost is expected to be recognized over the weighted-average 
period of 3.5 years.  The stock-based compensation expense for the years ended January 31, 2009, 2008 and 2007 was 
$745,000, $504,300 and $138,400, respectively. 

Note 10 - Stock Rights 

On September 15, 1999, the Company’s Board of Directors declared a dividend of one common stock purchase right (a 
“Right”) for each share of MFRI’s common stock outstanding at the close of business on September 22, 1999.  The stock 
issued after September 22, 1999 and before the redemption or expiration of the Rights is also entitled to one Right for 
each such additional share.  Each Right entitles the registered holders, under certain circumstances, to purchase from the 
Company one share of MFRI’s common stock at $25.00, subject to adjustment.  At no time will the Rights have any 
voting power. 

The Rights may not be exercised until 10 days after a person or group acquires 15% or more of the Company’s common 
stock, or announces a tender offer that, if consummated, would result in 15% or more ownership of the Company’s 
common stock.  Separate Rights certificates will not be issued and the Rights will not be traded separately from the stock 
until then.  Should an acquirer become the beneficial owner of 15% or more of the Company’s common stock, Rights 
holders other than the acquirer would have the right to buy common stock in MFRI, or in the surviving enterprise if MFRI 
is acquired, having a value of two times the exercise price then in effect.  Also, MFRI’s Board of Directors may exchange 
the Rights (other than those of the acquirer which will have become void), in whole or in part, at an exchange ratio of one 
share of MFRI common stock (and/or other securities, cash or other assets having equal value) per Right subject to 
adjustment.  The Rights described in this paragraph and the preceding paragraph shall not apply to an acquisition, merger 
or consolidation approved by the Company’s Board of Directors. 

The Rights will expire on September 15, 2009, unless exchanged or redeemed prior to that date.  The redemption price is 
$0.01 per Right.  MFRI’s Board of Directors may redeem the Rights by a majority vote at any time prior to the 20th day 
following public announcement that a person or group has acquired 15% of MFRI’s common stock.  Under certain 
circumstances, the decision to redeem requires the concurrence of a majority of the independent directors.

The fourth quarter for 2008 and 2007 had net losses; therefore the diluted earnings per share for the quarters were 
identical to the basic earnings per share rather than assuming conversion, exercise, or contingent issuance of securities that 
would have an anti-dilutive effect on earnings per share.  In the 2008 fourth quarter, the Company recognized a non-cash 
$2,788,000 impairment of goodwill which was recorded as part of continuing operations.  The goodwill impairment 
charge related to the Company’s filtration products and industrial process cooling equipment businesses.
