Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

BASIS OF PRESENTATION 

This management’s discussion and analysis of the financial results of Westport Innovations Inc. (“Westport”, 

“the  Company”,  “we”)  should  be  read  in  conjunction  with,  and  is  qualified  by,  Westport’s  Consolidated 

Financial  Statements  and  related  notes  for  the  year  ended  March  31,  2006  (the  “Financial  Statements”), 

which have been prepared in accordance with Canadian generally accepted accounting principles (“GAAP”).  

Reference should be made to Note 20 of the Financial Statements for a reconciliation of Canadian and U.S. 

generally accepted accounting principles.  All of the information presented herein is expressed in Canadian 

dollars, unless otherwise stated.  Certain prior year amounts have been reclassified to conform to the current 

year presentation.

This management’s discussion and analysis is dated June 13, 2006. 

BUSINESS OVERVIEW 

Westport is engaged in the research, development and marketing of high performance, low-emissions engine 

and  fuel  systems  which  use  gaseous  fuels  such  as  natural  gas,  propane  or  hydrogen.    We  expect  strong 

demand  for  these  products  for  transportation,  power  generation  and  industrial  applications  because  of  the 

performance, emissions characteristics and life-cycle costs when compared to alternatives now available or 

known  to  be  under  development  for  these  applications.    Our  strategy  is  to  develop  our  technologies  and 

products  in  cooperation  with  the  world’s  leading  engine  and  vehicle  manufacturers  and  fuel  infrastructure 

providers.  To date, we have established cooperative fuel system development programs with a number of 

1 

 
 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

automotive companies including Isuzu, Ford and BMW, and are in various stages of negotiations to develop 

and  commercialize  our  technologies  with  Energy  Developments  Limited  of  Australia  (“EDL”  or  “ENE”), 

Weichai  Power  Co.  Ltd.,  and  others.    We  have  also  announced  our  intention  to  form  a  joint  venture  to 

develop and market liquid natural gas tanks for the transportation market with Beijing Tianhai Industry Co. 

Ltd,  a  Chinese-Korean  company  with  its  headquarters  and  manufacturing  facilities  in  China.    We  already 

have  one  commercial  joint  venture,  Cummins  Westport  Inc.  (“CWI”),  with  Cummins  Inc.  (“Cummins”),  a 

global  power  leader  in  engines,  power  generation  and  other  related  technologies  based  in  Columbus, 

Indiana.  As at March 31, 2006, we also held an approximate 8% investment interest in Clean Energy Fuels 

Corp., North America’s largest provider of vehicular natural gas. 

We  currently  have  one  operating  segment,  which  involves  the  research,  development,  and  related 

commercialization of engines and fuel systems operating on gaseous fuels such as natural gas and hydrogen.  

Our share of the assets, liabilities, revenue and expenses of CWI are disclosed separately in note 15 of our 

financial  statements.    We  are  focused  primarily  on  the  development  and  commercialization  of  advanced 

proprietary  technologies  related  to  the  use  of  cleaner  burning  natural  gas  and  other  gaseous  fuels  in 

traditional  internal  combustion  engines.    Our  joint  venture,  CWI,  is  focused  on  the  development,  marketing 

and  sale  of  mid-range  natural  gas  or  LPG  engines  for  transit  bus,  shuttle  and  urban  specialty  vehicles.  

Geographically,  CWI’s  revenues  are  derived  mainly  from  North  America  with  strong  interest  and  markets 

developing in China, India, Europe and South America. 

In  2005,  we  observed  three  trends  that  we  believed  would  drive  significant  changes  in  the  global 

transportation industry: 

1.  Slowing growth of oil production in a time of fast-growing demand, particularly from China and India.  As a 

result, countries are increasingly looking towards alternative fuels for transportation, such as natural gas. 

2.  Rapid  urbanisation,  particularly  in  Asia,  creating  demand  for  private  cars,  public  transit  vehicles  and 

trucks for transportation of goods. 

3. 

Increasing recognition of transportation as a primary and growing contributor to complex environmental 

challenges, including urban air pollution and climate change. 

In the past twelve months, we have seen the world oil prices increase from approximately $50 per barrel to 

over $70 per barrel.  While oil prices have occasionally spiked in reaction to world events such as instability in 

the Middle East and Hurricane Katrina, we believe the overall trend will continue to be increasing oil prices as 

diminishing supply and increasing demand keep oil prices at or above current levels requiring governments to 

look for alternative energy sources such as natural gas, nuclear, solar, wind, clean coal and others.  However, 

solutions  for  transportation  will  be limited.   While many  alternatives other  than natural  gas  such  as nuclear 

2 

 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

and coal, can be used for power generation, there is no obvious solution for transportation, which currently 

accounts for 57% of the world’s energy use and 21% of the pollutants.  

We  believe  we  can  capitalise  on  these  trends  through  our  patented  technologies  and  by  expanding  our 

market-focused  partnership  strategies.    By  partnering  with  original  equipment  manufacturers,  governments, 

infrastructure providers, and end-users, we have been able to deliver complete solutions to vehicle fleets for 

over a decade.  We also recognise that while natural gas has significant environmental benefits over diesel, 

we must also have a cost effective solution for fleet owners to change fuels.  Accordingly, by working in every 

segment of the supply chain, we are helping to ensure the whole system operates effectively to deliver cost 

effective solutions to the customer.  

In fiscal  2006,  we made  a substantial shift  to move our  business  from being  technology focused to market 

driven:  

•  We  increased  non-CWI  related  sales  and  marketing  expenditures  by  approximately  $1.3  million 

(excluding stock-based compensation). 

• 

• 

• 

• 

In August, 2005, we announced our intention to form a joint venture to develop and market liquid 

natural gas tanks for the transportation market with Beijing Tianhai Industry Co. Ltd., a Chinese-

Korean company with its headquarters and manufacturing facilities in China.   

In September, 2005, we signed a letter of intent with Weichai Power Co. Ltd., a Hong Kong listed 

Chinese engine manufacturer, to cooperate on the development, marketing and sales of gaseous-

fuelled engines and vehicles for the Chinese market.   

In November, 2005, we entered into an exclusive arrangement with Energy Developments Limited 

to conduct business planning for liquefied natural gas mine trucks.  With the initial feasibility study 

completed, EDL agreed to pay us approximately $130,000 to complete a detailed program plan, 

budget, and a joint business plan for the commercialization of the LNG mine truck retrofit product.  

The proposed program forms part of EDL’s plans for expanding LNG production and distribution in 

Australia. 

In December, 2005, we signed a $1.5 million, one year development agreement with Isuzu Motors 

Limited of Japan to demonstrate up to 25% fuel economy improvement using our Compressed 

Natural Gas Direct Injection (CNG-DI) technologies compared to Isuzu’s current spark-ignited CNG 

engines.  We expect to deepen our working relationship with Isuzu in this phase of the agreement 

and have commenced discussions on an Intellectual Property Rights framework.

•  We announced in March, 2006 that our HPDI system adapted to a Cummins ISX engine had been 

certified by the California Air Resources Board and was ready for commercial deployment for 2006 

deliveries. 

We  also  saw  these  global  macro-economic  trends  benefit  CWI’s  business.  CWI  successfully  completed  its 

limited production launch of its B-Gas International (“BGI”) natural gas engine in India.  Local assembly of the 

engine takes  place at Cummins  India  Limited’s (“CIL”) modern  Daman  facility  in Western  India.  CIL is  also 

responsible for sales and distribution for the local Indian market with CWI providing kits for local assembly and 

related parts.  This launch marks CWI’s entry into the Indian market which has not been addressable in the 

past  because  of  high  import  tariffs  and  duties.    CWI  also  announced  in  October  that  it  had  finalised  an 

agreement  with  Dongfeng  Cummins  Engine  Company  (“DCEC”)  for  manufacturing  of  CWI’s  BGI  engine  in 

China.    In  March  2006,  CWI  also  announced  a  278  unit  order  of  C-Gas  Plus  engines  in  Russia.    While 

international markets continue to provide significant growth opportunities for CWI, 82% of its revenues in 2006 

continued to be generated in North America where government incentives play a significant role. 

On  June  12,  2006,  we  announced  that  Perseus,  L.L.C.  (“Perseus”),  a  US  based  private  equity  fund 

management company, would be strategically investing up to $22.1 million in Westport.  This transaction is 

more fully described in the Capital Requirements, Resources and Liquidity section of this MDA.

Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

Over  the  past  three  years  we  have  continued  our  strategy  of  increasing  shareholder  value  by  growing  our 

sales and gross margins, transitioning our business from technology to market development, reducing our net 

investments  in  research  and  development,  and  increasing  development  funding  from  government  and 

industry partners.  We have reduced our net loss from $37.7 million in fiscal year 2004 to $26.2 million in 2005 

to $16.9 million in 2006, an overall reduction of 55%.   We have also reduced cash used in operations before 

changes  in  working  capital  from  $25.0  million  in  2004  to  $13.6  million  in  2005  to  $8.7  million  in  2006,  an 

overall reduction of 65%.  Revenues in this three year period have increased by 34% on modest unit growth 

and  higher  parts  revenue  as  the  result  of  changes  made  in  parts  revenue  accounting  from  net  revenue 

reporting to gross revenue reporting when we amended the CWI joint venture agreement in December, 2003 

and  from  increased  parts  sale  volumes.    Our  plan  is  to  continue  to  aggressively  grow  revenues,  pursue 

funding and to manage our costs while maintaining our technology leadership position in the alternative fuels 

market as we drive towards profitability. 

CRITICAL ACCOUNTING POLICIES AND ESTIMATES 

Financial statement preparation requires that we use estimates and assumptions that affect the reported amount 

of assets and liabilities as well as revenues and expenses.  Our accounting policies are described in note 2 to 

our  Financial  Statements.    The  following  policies  have  a  significant  impact  on  the  consolidated  financial 

statements or are impacted significantly by judgments, assumptions and estimates used in the preparation of our 

consolidated financial statements.   

Variable Interest Entity Accounting 

In  June  2003,  the  Canadian  Institute  of  Chartered  Accountants  issued  Accounting  Guideline  15  AcG-15 

“Consolidation of Variable Interest Entities” which applies to annual or interim periods beginning on or after 

November 1,  2004.    A Variable  Interest  Entity  (“VIE”) is  any  type of legal structure  not controlled by  voting 

equity, but rather by contractual and/or other financial arrangements.  Interests in VIE’s are consolidated by 

the company that is the primary beneficiary.  Westport has identified CWI as a VIE, determined that we are 

the  primary  beneficiary,  and  accordingly  consolidate  CWI,  reflecting  100%  of  CWI’s  assets,  liabilities, 

revenues and expenses in our financial statements and showing the 50% interest held by Cummins Inc. as 

“Joint Venture Partner’s share of income from joint venture”. 

Warranty Liability 

Estimated warranty costs are recognised at the time CWI sells its products and included in cost of revenues.  

CWI uses historical failure rates, and costs to repair product defects during the warranty period, together with 

information on known products to estimate the warranty liability. The ultimate amount payable and the timing 

will depend on actual failure rates and the actual cost to repair.  Since many of CWI’s products are new to the 

6 

 
 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

market  and  the  majority  of  its  engines  are  still  under  warranty,  historical  data  may  not  necessarily  reflect 

actual costs to be incurred and exposes us to the potential for significant positive or negative fluctuations in 

the warranty liability.  CWI reviews its warranty provision quarterly and makes adjustments to its assumptions 

based on the latest information available at that time.  Adjustments to the warranty provision are recorded in 

cost of revenues. 

Revenue Recognition 

Product revenue is recognised, net of estimated costs of returns, allowances, and sales incentives, when the 

products are shipped and title passes to the customers.  Shipments of most products and parts sold by CWI 

originate  from  Cummins’  facilities.    Revenue  also  includes  fees  earned  from  performing  research  and 

development activities for third parties.  Revenue from research and development activities is recognised as 

the services are performed.  Amounts received in advance of revenue recognition are recorded as deferred 

revenue. 

Parts revenue is recognised as the parts are sold.  

Inventory 

In establishing whether or not a provision is required for inventory obsolescence, we estimate the likelihood 

that inventory carrying values will be affected by changes in market demand for our products and by changes 

in  technology,  which  could  make  inventory  on  hand  obsolete.    We  perform  regular  reviews  to  assess  the 

impact of changes in technology, sales trends and other changes on the carrying value of inventory.  If and 

when we were to determine that such changes have occurred and that they would have a negative impact on 

the carrying value of inventory on hand, adequate provisions would be made.   Unforeseen changes in these 

factors could result in additional inventory provisions being made.   

Long-term Investments 

We account for long-term investments in non-consolidated entities using the equity method to the extent that 

we have significant influence over the investee’s strategic operating, financing and investing policies.  All other 

long-term investments are accounted for using the cost method.  Long-term investments are reduced to market 

value only to the extent that the loss in value is other than temporary.  In determining market value for our long-

term investments, which are privately held companies, we use assumptions around future cashflows from the 

investments,  recent  equity  transactions  involving  its  investees  and  the  current  financial  performance  of  the 

investees to determine fair value.  In the  year ended  March  31, 2005, we determined that our investment in 

Edge  Technologies  Inc.,  had  suffered  a  permanent  impairment  in  value  and  accordingly,  wrote  down  our 

investment by $3.1 million.  We account for our interest in Clean Energy at cost. 

7 

 
 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

Equipment, Furniture, and Leasehold Improvements and Intellectual Property 

Generally accepted accounting principles in Canada require that we consider whether or not there has been 

an  impairment  in  our  long-lived  assets,  such  as  equipment,  furniture  and  leasehold  improvements  and 

intellectual  property,  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  value  of  the 

assets may not be recoverable.  If such costs are not recoverable, we are required to write down the assets to 

fair value.  When quoted market values are not available, we use the expected future cashflows discounted at 

a rate commensurate with the risks associated with the recovery of the asset, as an estimate of fair value to 

determine  whether  or  not  a  write  down  is  required.    For  the  year  ended  March  31,  2005,  we  adjusted  the 

carrying value of our equipment, furniture and leasehold improvements by $0.4 million.  For the year ended 

March 31, 2006, we determined that no adjustments were required. 

CHANGES IN ACCOUNTING POLICY 

Financial Instruments 

Effective  for  our  fiscal  year  beginning  April  1,  2005,  we  adopted  the  amended  provisions  of  Handbook 

Section  3860  –  “Financial  Instruments  –  Disclosure  and  Presentation”  related  to  financial  instruments  that 

are contractual obligations of a fixed amount but are settleable with our common shares.  Amendments to 

Handbook Section 3860 require that these instruments be classified as liabilities rather than shareholders’ 

equity  because they  do not  represent  a residual  interest  in Westport  until the common  shares are  issued.  

Accordingly,  the  value  assigned  to  the  Technology  Partnerships  Canada  (“TPC”)  warrants  and  the  GVH 

Entwicklungsgesellschaft  für  Verbrennungsmotoren  and  Energietechnik  mbH  (“GVH”)  obligation  to  issue 

shares, both of which were previously included in “Other Equity Instruments”, are in substance a liability to 

us, because the number of common shares to be issued is determined based on a fixed contractual amount 

of fair value due to TPC and the vendors of GVH.  These fixed contractual amounts will be settleable with 

equity instruments with the number of such instruments to be determined based on the market value of our 

common shares on the date these instruments are settled. We changed our accounting policy to treat these 

amounts as liabilities effective April 1, 2005 and have restated the comparative figures on a consistent basis.  

DISCLOSURE CONTROLS 

We have disclosure controls and procedures in place that are designed to provide reasonable assurance that 

material information  relating to Westport is  disclosed on  a  timely  basis.    We have  reviewed  our  disclosure 

controls and have concluded that they were effective during the reporting period.

Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

FINANCIAL OVERVIEW 

For the years ended March 31, 2006 and 2005, total revenues were $43.6 million, up 26% from $34.4 million,  

primarily  because  of  changes  in  product  mix  and  higher  parts  revenue.    Net  loss  decreased  by  36%  from 

$26.2 million, or $0.38 per share, to $16.9 million, or $0.23 per share primarily as the result of higher gross 

margins ($4.2 million) and decreased depreciation and amortization expenses ($3.6 million) offset by a $1.5 

million increase in our joint venture partner’s 50% share of CWI income.  In 2005, we also wrote down our 

investments by $3.1 million and our equipment, furniture and leasehold improvements by $0.4 million.  For the 

year  ended  March  31,  2006,  cash  used  in  operations  before  changes  in  working  capital  was  $8.7  million, 

down from $13.6 million in 2005 primarily resulting from the higher gross margins.  

For the year ended March 31, 2006, CWI’s income for the year was $3.2 million, up from $0.2 million in the 

prior  year.    The  $3.0  million  increase  was  primarily  the  result  of  a  27%  increase  in  revenues  and  a  40% 

increase  in  associated  gross  margin  contribution.    CWI’s  business  model  –  leveraging  existing  Cummins 

facilities and distribution channels – has been highly scalable, allowing CWI to increase gross margins without 

incurring significant additional operating costs.  After taking into account Cummins’ 50% share of profits, CWI 

contributed $1.6 million in net income to our consolidated results.  

RESULTS FROM OPERATIONS 

Revenues  for  the  year  ended  March  31,  2006  were  $43.6  million  compared  to  $34.4  million  in  2005. 

Revenues, cost  of  sales  and  gross  margin are  sensitive to product  mix,  customer  sales cycles  and  foreign 

exchange  fluctuations  (both  revenue  and  cost  of  sales,  including  warranty,  are  US  dollar  denominated).  

During the year, the US dollar weakened by approximately 7% against the Canadian dollar. 

Product revenue was $29.9 million for the year ended March 31, 2006, up 17% from 2005 revenues of $25.7 

million  on  1327  units  shipped  compared  to  1277  in  the  prior  year.    The  higher  per  unit  revenue  reflects  a 

change  in  geographical  mix.    In  2005,  a  higher  proportion  of  sales  consisted  of  lower  priced  B  engines 

shipped to China.  In 2006, sales consisted largely of higher horse power C-plus and L-plus engines with 4% 

of total revenues from China compared to 24% in the prior year.   Non-CWI revenues were relatively flat at 

$1.3 million in 2006 compared to $1.2 million in 2005.

Parts  revenue  for  the  year  ended  March  31,  2006  was  $13.6  million  compared  to  $8.8  million  in  2005, 

reflecting an updated and expanded parts list negotiated with Cummins during the year.  Parts revenue is a 

function of engine population, failure rates and price. 

Cost of revenue increased to $28.6 million in the year ended March 31, 2006 from $23.8 million in the prior 

year,  or  66%  and  69%  of  total  revenues  respectively.    Cost  of  revenue  includes  production  costs  and  the 

associated warranty.  

Estimated warranty costs are recognised at the time CWI sells its products and included in cost of revenues.  

CWI  uses  historical  failure  rates,  and  costs  to  repair  product  defects  during  the  warranty  period,  together 

with information on known products to estimate the warranty liability. The ultimate amount payable and the 

timing will depend on actual failure rates and the actual cost to repair.  Since many of CWI’s products are 

new to the market and the majority of its engines are still under warranty, historical data may not necessarily 

reflect  actual  costs  to  be  incurred  and  exposes  us  to  the  potential  for  significant  positive  or  negative 

fluctuations in the warranty liability.  CWI reviews its warranty provision quarterly and makes adjustments to 

its assumptions based on the latest information available at that time.  Adjustments to the warranty provision 

are recorded in cost of revenues.  During the year, as the actual claims experience continued to be lower 

than the expected experience at the time of the initial warranty accrual, CWI changed its estimated warranty 

liability balance, reducing its warranty liability and cost of sales by $1.8 million (2005 - $1.1 million).

for the years ended March 31, 2006 and 2005 

Gross margin was $14.9 million for the year ended March 31, 2006, or 34% of total revenues compared to 

$10.7  million  in  2005,  or  31%  of  total  revenues.      Product  gross  margin  percentages  improved  from  an 

average margin of approximately 30% to 37% during the year as the result of lower estimated warranty costs 

associated with improved product reliability and customer, application and product mix.  Excluding the change 

in  estimated  warranty  liability,  gross  margin  percentage  for  the  year  would  have  been  approximately  30%.  

Parts margins dropped from approximately 36% to 28% with the re-negotiated and expanded parts list in the 

year including lower margin items and higher standard costs. 

Research and development expenses were $16.9 million and $18.4 million for the years ended March 31, 

2006 and 2005 respectively.  Excluding stock based compensation of $1.6 million and $0.4 million, research 

and  development  expenses  were  $15.3  million  and  $18.0  million  for  the  years  ended  March  31,  2006  and 

2005.    The  $2.7  million  decrease  excluding  stock  based  compensation  was  due  primarily  to  increased 

government funding which increased from $6.0 million to $8.7 million year over year.  The $1.2 million increase 

in stock based compensation related to a special grant of stock options in the year to all employees.  For the 

year  ended  March  31,  2006,  CWI  research  and  engineering  costs  remained  flat  at  $6.6  million,  or 

approximately  39%  of  consolidated  net  research  and  development  costs.    The  remaining  amounts  were 

invested primarily in our heavy-duty and light-duty development and demonstration programs.

General and administrative expenses for the year ended March 31, 2006 decreased from $5.6 million in 

2005 to $4.9 million primarily because of a $0.4 million decrease in associated stock based compensation 

and resources reallocated to sales and marketing.   

Sales and marketing expenses for the year ended March 31, 2006 increased by $2.0 million to $5.8 million 

from $3.9 million in 2005.  CWI sales and marketing expenses increased by $0.4 million primarily because of 

increased costs in Europe, some of which had been shared with Cummins in the prior year.  Non-CWI sales 

and marketing expenses increased by $1.3 million (excluding stock-based compensation) with our increased 

focus on new business development, particularly in China. Stock based compensation also increased by $0.3 

million with a special grant of stock options to all employees in the year.

Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

Foreign exchange gain of $0.1 million for year ended March 31, 2006 primarily reflects the realised net 

gains and losses on foreign currency transactions and the net unrealised gains and losses on our net US 

dollar denominated assets and liabilities, which consist primarily of US dollar short-term investments and 

warranty.  The Canadian dollar has strengthened by 7% during the year.  In the prior year, we recognised a 

foreign exchange gain of $0.6 million, primarily of the translation of US dollar denominated warranty 

balances. 

Depreciation and amortization for the years ended March  31, 2006 and 2005 were $2.8 million and $6.3 

million respectively.  The $3.6 million decrease in the year resulted from certain intellectual property, 

equipment and furniture being fully amortized as of March 31, 2005.  In addition, effective July 1, 2006, we 

changed our estimates of the useful life of our research and development machinery and equipment from 

five to eight years. The net impact of this change in estimate was approximately $1.1 million for the year.  

Remaining intellectual property is being amortized over seven years. 

Write down of equipment, furniture, and leasehold improvements of $0.4 million in the year ended March 

31, 2005 related to impairments in value associated with equipment and leasehold improvements located in 

Vancouver and Germany.  No write downs were considered necessary in 2006. 

Write  off  of  long-term  investments  of  $3.1  million  for  the  year  ended  March  31,  2005  related  to  our 

determination that our investment in Edge Technologies Inc., of Ames, Iowa, had been permanently impaired.  

We  continue  to  hold  the  exclusive,  royalty-free  worldwide  rights  to  use  and  make  Edge’s  Terfenol-D 

technology in gaseous fuel engine applications and to work with Edge on its development.  We use Terfenol-

D, which quickly expands or contracts in the presence of a magnetic field, to govern the flow of fuel through 

natural gas injectors for high speed diesel engines. 

Joint Venture Partner’s share of income from joint venture for the year ended March 31, 2006 of $1.6 

million (2005 - $0.1 million) reflects Cummins’ 50% share of CWI net operating contribution in the period.  

Since January 1, 2005, Cummins has shared equally in any CWI profit or loss. 

CAPITAL REQUIREMENTS, RESOURCES AND LIQUIDITY 

As at March 31, 2006, our cash, cash equivalents and short-term investment position was $7.8 million.  We also 

have a $13 million credit facility with our bank, which has been drawn down by our demand instalment loan of 

$2.5 million, capital leases of $0.3 million, and a $0.6 million letter of credit.  We have also relied on public and 

private sources of equity financing to fund our operations.  Since our incorporation in 1995, we have raised $230 

million in common share equity primarily from a number of private and public offerings.

Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

On June 12, 2006, we agreed to issue up to $22.1 million in 5 year secured, subordinated convertible notes with 

a coupon rate of 8% to Perseus of Washington, DC, a private equity fund management group.  The notes are to 

be issued in two tranches of $13.8 million and $8.3 million, respectively.  Interest will be payable semi-annually in 

arrears in additional notes or shares for the first two years, at our option.  After the first two years, interest will be 

calculated at a rate of  8% on the outstanding principal amount only for the number of trading days in the period 

on which the share price is below $3.00 and is payable semi-annually in cash, additional convertible notes or 

shares at our option.  The first tranche is convertible to common shares at a conversion price of $1.30 at any 

time during the term of the notes and the second tranche is convertible to common shares at a conversion price 

equal to $1.40.   At the time of issuance, the noteholder will also receive warrants to acquire, at an exercise price 

equal  to  the  conversion  price  of  the  accompanying  notes,  common  shares  of  Westport  equal  to  25%  of  the 

number of common shares into which the notes are convertible.  The term to expiry of the warrants is four years 

from  the  date  of  issuance  and  the  warrants  include  a  cashless  exercise  provision  which  would  allow  the 

noteholder to receive the number of common shares having a value equal to the net gain that would be realized 

by the noteholder had the warrant been exercised for cash and the related shares sold at the market price on the 

date the option is exercised.  Any warrants under the cashless exercise provision converted will be cancelled.  

For  so  long  as  Perseus  continues  to  hold  notes  and  warrants  convertible  into  a  specified  percentage  of 

Westport's issued and outstanding shares, Perseus will also be entitled to nominate two of seven board seats.  

The notes will be secured with a second charge on all of our assets.   

$5.5 million of the first tranche of $13.8 million has been received with the balance due by July 15, 2006.  The 

second tranche of $8.3 million, the proceeds of which are to be used for a new business venture, is subject to 

receiving Westport shareholder approval and the Company meeting certain milestones within 180 days of the 

receipt of such shareholder approval.  

On June 13, 2006, we also entered into an agreement with Matco Capital Ltd. (“Matco”) to reorganize Westport 

Research Inc (“WRI”), a wholly owned subsidiary of Westport.  We will transfer all of the current assets, liabilities 

and operations of WRI to other wholly owned Westport companies. Matco will then acquire a 45% equity interest 

in WRI, following which we and Matco will source and pursue other opportunities to maximize the value of our 

respective interests in WRI. The reorganization and share sale is expected to close on or before July 31, 2006.  

We expect to access at least $10 million in cash on closing with the ultimate amount to be determined by the 

value of the reorganized WRI, including any new ventures. 

In the prior fiscal year ending March 31, 2005, we had entered into a bought deal financing agreement with a 

syndicate of investment dealers to issue 9.0 million units, each consisting of one of our common shares and one-

half of one warrant.  One full warrant entitles the holder to purchase one of our common shares upon payment of 

13 

 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

$2.10 on or before March 29, 2006.  The financing raised $15.1 million in net proceeds.  As at March 31, 2006, 

no warrants were outstanding.  

As at March 31, 2005, we had $20.3 million in cash and short-term investments.  During the year ended March 

31, 2006, we used $8.7 million for operations and $3.0 million for working capital purposes. Inventory held by 

CWI in China and sold during the year contributed $0.6 million of working capital but was offset by the release of 

$1.2 million in deferred revenue.  Deferred revenue relates primarily to amounts advanced to CWI by Cummins 

based on the terms of the amended joint venture agreement, but where the engines have not yet been shipped 

to  the  final  customer.    Accounts  payable  consumed  $1.2  million  primarily  because  of  higher  trade  payables 

associated  with  the  increase  in  government  funded  work  in  the  fourth  quarter  of  2005  which  were  paid  to 

suppliers in 2006.  Warranty liabilities also used $1.0 million in working capital.  We also used $0.4 million to 

acquire  equipment,  furniture  and  leasehold  improvements,  drew  down  a  further  $1.2  million  against  our  bank 

credit line and repaid $1.7 million of loans and other debt obligations.  

We believe that our current cash, cash equivalents and short-term investments, our investment in Clean Energy 

and the commitment received from Perseus and Matco provide us with sufficient capital to meet our committed 

milestones and obligations for our current programs.  Our capital requirements will vary depending on a number 

of factors, including the contributions from the sales of products and parts, progress of our current programs, any 

decisions by us and our current engine partners to enter into new program phases and any decision by us to 

establish  additional  programs  or  strategic  alliances.  In  addition,  we  review  investment  and  acquisition 

opportunities  on  a  regular  basis  for  technologies,  businesses  and  markets  that  would  complement  our  own 

products or assist us in our commercialization plans. 

Significant new or expanded engine programs, acquisitions or investments could require additional funding.  If 

such additional funding is not available to us, or if we have significant overspending in our programs, we may 

be required to delay, reduce or eliminate certain research and development activities and possibly forego new 

program,  acquisition  or  investment  opportunities.    Any  of  those  circumstances  could  potentially  result  in  a 

delay of the commercialization of our products in development. 

SHARES OUTSTANDING 

During  the  year  ended  March  31,  2006,  we  granted  3,178,218  stock  options  with  various  vesting  terms.  

1,692,933 employee share options vest 1/3 if and when the stock price increases 20% over the price on the 

grant date, 1/3 if and when the share price increases 35% and 1/3 if and when the stock price increases 50%, 

all such prices are calculated on a rolling average over twenty consecutive trading days. The stock price on 

the  grant  date  was  $1.51  per  share.    1,167,144  share  options  granted  pursuant  to  Westport’s  Executive

Compensation  Plan  vest based on  the earlier of  the attainment of a $5.00 share  price as a  rolling average 

over twenty consecutive trading days, and the 5th anniversary of the grant date.  During the year, 612,070 

share options expired or were cancelled.   

For the year ended March 31, 2006, we also granted pursuant to the 2003 Performance Share Unit (“PSU”) 

Plan and Annual Bonus plan 816,919 PSU's of which 316,919 vested on the date of grant and with 300,000 

vesting  only  on  the  achievement  of  performance  milestones  approved  by  the  Board  of  Directors.  The 

remainder vest over time.  4,499,450 warrants with an exercise price of $2.10 expired on March 29, 2006. 

For  the  year  ended  March  31,  2006,  the  weighted  average  number  of  shares  used  in  calculating  loss  per 

share  was  74,228,495.     Actual shares outstanding as of  March 31, 2006  were 74,391,779.   As  March 31, 

2006, we had nil warrants outstanding, 4,968,563 share options outstanding at a weighted average exercise 

price  of  $2.05  and  1,431,125  performance  share  units  outstanding.    Of  the  share  options  outstanding, 

1,544,266 options were exercisable at a weighted average exercise price of $3.22.  Of the performance share 

units outstanding, 587,142 were exercisable.   

Subsequent  to  March  31,  2006,  on  April  28,  2006,  under  our  obligations  to  GVH,  we  also  issued  214,000 

Euros worth of shares, which translated into 293,924  shares.  

As of June 13, 2006, we had 74,685,703 shares outstanding, 1,062,115 warrants outstanding and 4,956,558 

options outstanding at a weighted average price of $2.04, of which 1,527,625 were exercisable at a weighted 

average  exercise  price  of  $3.19  and  1,746,841  performance  share  units  outstanding,  of  which  1,346,842 

were exercisable.  We also had a convertible note for $5.5 million outstanding at a conversion price of $1.30.

Our  net  loss  in  the  three  months  ended  March  31,  2006  was  $3.7  million  compared  to  $9.3  million  for  the 

same  period last  year  with product  revenues of  $8.7 million  on 388  units shipped compared  to $8.5 million 

and 445 units shipped in the prior year.  Unit sales can vary significantly from quarter to quarter depending on 

customer delivery dates.  In the three months ended March 31, 2005, shipments to China accounted for more 

than half of the shipments while shipments in the fourth quarter of fiscal 2006 consisted of primarily sales of 

larger,  more  expensive  engines  to  North  American  customers.      Accordingly,  revenues  were  comparable 

despite  a 13%  decrease  in  unit shipments.  Parts  revenue  was  $3.5  million  compared to $1.9 million  in  the 

fourth quarter of 2005.  In 2005, our write off of our investment in Edge also accounted for $3.1 million of the 

$9.3 million loss in the quarter.  Depreciation for the fourth quarter of 2006 was $0.5 million compared to $1.5 

million in  the same quarter  last  year.    Operating cash  use in  the  quarter,  defined  as “cash  from operations 

before changes in non-cash working capital”, was $2.0 million.

BUSINESS RISKS AND UNCERTAINTIES 

Our ability to generate revenue and profit from our technologies is dependent on a number of risks.  The risks 

and uncertainties described below are not the only ones we face.  Additional risks and uncertainties, including 

those that we do not know about now or that we currently believe are immaterial may also adversely affect our 

ability to generate revenue and profit. 

We Have Incurred, and Continue to Incur, Losses 

We  have  incurred  substantial  losses  since  we  were  founded,  and  continue  to  incur  losses.    We  had  an 

accumulated deficit of $229 million as of March 31, 2006.  We cannot predict when we will operate profitably, 

if ever. Without a significant new revenue stream, at our current spend rate, we expect to continue to incur net 

losses for at least the next year as we continue to invest in research and product development activities to 

achieve commercialization of our products. 

We May Never Produce Commercially Viable Fuel Systems 

We  do  not  know  when  or  whether  we  will  successfully  complete  development  of  commercially  viable  fuel 

systems for any of our target and prospective markets on a mass market basis.  Our patented high pressure 

direct  injection  (HPDI)  technology  has  been  demonstrated  in  engines  in  our  heavy-duty  trucking,  light-duty 

vehicle, and high horsepower programs.  However, there can be no assurance that these and other engines 

18 

 
 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

using our fuel systems will always perform as well as we expect, or that prototypes and commercial systems 

will be developed and sold in commercially viable numbers. 

Potential Fluctuations in Our Financial Results Makes Financial Forecasting Difficult 

We expect our revenues and operating results to vary significantly from quarter to quarter.  Sales and margins 

may  be  lower  than  anticipated  due  to  general  economic  and  market-related  factors,  product  quality, 

performance  and  safety  issues  and  competitive  factors.    As  a  result,  quarter-to-quarter  comparisons  of  our 

revenues and operating results may not be meaningful.  In addition, due to our early stage of development, 

we cannot accurately predict our future revenues or results of operations.  It is likely that in one or more future 

quarters  our  operating  results  will  fall  below  the  expectations  of  securities  analysts  and  investors.    If  this 

happens, the trading price of our shares might be materially and adversely affected. 

We May Be Unable to Raise Additional Capital 

Our  product  development  and  commercialization  schedule  could  be  delayed  and  our  viability  could  be 

jeopardised if we are unable to raise additional money to fund our research, market and product development 

activities.  We mitigate this risk by generating funds from a variety of sources including: through the sale of 

our commercial products, through funding from governments, industry and engine development partners, and 

through the issuance of shares or debt in the public equity markets or through strategic investors.  In addition, 

we maintain reserves of cash and short-term investments, are conservative and prudent in our expenditures 

and seek to obtain funding commitments before we take on any significant incremental initiatives.  There can, 

however, be no assurance that we will be able to secure additional funding, or funding on terms acceptable to 

us, to pursue our commercialization plans. 

Warranty Claims Could Diminish our Margins 

CWI’s commercially available products and parts contributed revenues of $42.3 million and gross margins of 

$14.9  million  during  fiscal  2006.    The  margins  contributed  by  these  sales  help  offset  our  costs  of  product 

development and other operating expenses.  There is a risk that the warranty accrual included in our cost of 

product  revenue  is  not  sufficient  and  that  we  may  recognise  additional  expenses  as  a  result  of  excessive 

warranty claims.  We mitigate these risks through our sales and marketing initiatives and our product quality, 

development,  support  and  service  programs.    However,  there  can  be  no  assurance  that  sales  of  our 

commercial products will continue to grow and contribute financially. 

We Must Lower the Cost of Our Fuel Systems and Demonstrate Their Reliability 

Our prototype HPDI fuel systems presently have significantly higher initial capital costs than many established 

competing technologies.  If we are unable to produce fuel systems that are competitive, on a life cycle costs 

basis, in terms of price, reliability and longevity, operators of commercial vehicle fleets and power generators 

19 

 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

will be unlikely to buy products containing our fuel systems.  The cost competitiveness of our products may 

also be affected by the level of government incentives and the price differential between diesel and natural 

gas, two factors beyond our control. 

Manufacturing costs of some of our products have not yet been confirmed.  We cannot guarantee that we will 

be  able  to  lower  these  costs  to  the  level  where  we  will  be  able  to  produce  an  economically  competitive 

product or that any product produced using lower cost materials and manufacturing processes will not suffer 

from a reduction in performance, reliability and longevity.  If a price premium is required to generate cash flow, 

customers may not accept it. 

We are Dependent on Our Relationships with Our Strategic Partners 

Our current strategy calls for cooperation, information exchanges and joint ventures with strategic partners, 

using  patents  and  written  agreements  to  advance  our  business  and  protect  our  intellectual  property.    The 

agreements  governing  these  relationships  allow  for  termination  by  our  partners  under  a  number  of 

circumstances.  Any change in our relationships with our strategic partners, whether as a result of economic 

or competitive pressures, including any decision by our strategic partners to reduce their commitment to our 

technology  in  favour  of  competing  technologies,  or  to  bring  to  an  end  our  various  alliances,  could  have  a 

material adverse effect on our business and financial results. 

There  can  be  no  assurance  of  the  commercial  success  of  joint  ventures  in  which  we  are,  or  will  become, 

involved.  There can be no assurance that existing technology agreements with engine manufacturers will be 

renewed or advanced into commercialization agreements on a timely basis.  There can also be no assurance 

that  we  will  be  able  to  develop  successful  relationships  with  other  multinational  OEMs.    In  addition,  our 

contractual  obligations  to  our  strategic  partners  require  that  we  provide  financial,  technical  and  human 

resources for the ongoing development of our products or expansion of our projects.  Our failure or inability to 

work successfully with our strategic partners could cause us to incur unanticipated expenses and losses or 

could delay the development of our products.  CWI is currently the only joint venture Westport has entered 

into. 

We Fund Research and Development Programs with Government Funding 

From  time  to  time,  we  enter  into  agreements  with  government  agencies  to  fund  our  research  and 

development programs.   There can be no assurance that we will be able to continue to receive funding at the 

same levels.   Funds received from government agencies are also subject to government audits. 

Our Field Tests Could Have Problems 

We are currently field-testing a number of our products and as part of our product developments cycles, we 

plan to conduct additional field tests in the future.  These field tests may encounter problems and delays for a 

20 

 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

number of reasons, including the failure of our technology, the failure of the technology of others, the failure to 

combine  these  technologies  properly  and  the  failure  to  maintain  and  service  the  test  prototypes  properly.  

Many of these potential problems and delays are beyond our control.  In addition, field test programs, by their 

nature, will involve delays and modifications.  Any problem or perceived problem with our field tests could hurt 

our reputation and the reputation of our products and delay their commercial launch. 

A Mass Market for Engines with Our Fuel Systems May Never Develop or May Take Longer to Develop than 

We Anticipate 

Engines  with  our  fuel  systems  represent  an  emerging  market,  and  we  do  not  know  whether  end-users  will 

ultimately want to use them or pay for their initial incremental cost. The development of a mass market for our 

fuel systems may be affected by many factors, some of which are beyond our control, including: 

• the emergence of newer, more competitive technologies and products; 

• the future cost of natural gas and other fuels used by our systems; 

• regulatory requirements / government incentives and penalties; 

• customer perceptions of the safety of our products; and 

• customer reluctance to try a new product. 

If a mass market fails to develop or develops more slowly than we anticipate, we may be unable to recover 

the losses we will have incurred in the development of our products and may never achieve profitability. 

We are Dependent on Our Relationship with Cummins and other Engine OEMs for Manufacturing and 

Distribution 

The majority of our revenues are currently derived from the operations of CWI, which in turn purchases all of 

its current and foreseeable engine products from Cummins affiliated plants.  Moreover, CWI distributes and 

supports  its  engine  products  and  parts  through  Cummins  distributors,  many  of  which  are  independently 

owned and operated. Although the factories operate with modern technology and experienced management, 

there can be no assurance that the factory and distribution systems will always be able to perform on a timely 

and cost-effective basis. 

To  be  commercially  useful,  our  fuel  systems  must  be  integrated  into  engines  and  our  engines  must  be 

integrated  into  chassis  manufactured  by  OEMs.    We  can  offer  no  guarantee  that  OEMs  will  manufacture 

engines  with  our  fuel  systems  or  chassis  for  our  engines,  or  if  they  do  manufacture  such  products,  that 

customers  will  choose  to  purchase  them.    Any  integration,  design,  manufacturing  or  marketing  problems 

encountered by OEMs could adversely affect the market for our products and our financial results. 

21 

 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

We are Dependent on Fuel Price Differentials that are Hard to Predict 

The acceptance of natural gas-fuelled engines by customers depends in part on the price differential between 

natural gas and diesel fuel.  Natural gas has generally been, and currently is, less expensive than diesel fuel 

in  many  jurisdictions.    This  price  differential  is  affected  by  many  factors,  including  changes  in  the  resource 

base for natural gas compared with crude oil, pipeline transportation capacity for natural gas, refining capacity 

for crude oil and government excise and fuel tax policies.  There can be no assurance that natural gas will 

remain less expensive than diesel fuel. 

We are Dependent on Growth in Natural Gas Refuelling Infrastructure That May Not Take Place 

For motor vehicles, natural gas must be carried on board in liquefied or compressed form and there are few 

public  or  private  refuelling  stations  available  in  most  jurisdictions.    We  are  involved  in  developing  such 

infrastructure  through  our  minority  ownership  interest  in  Clean  Energy,  the  largest  natural  gas  refuelling 

company for vehicles in North America.  However, there can be no assurance that Clean Energy will continue 

to be successful in expanding the availability of natural gas as a vehicle fuel, and there can be no assurance 

that  other  natural  gas  distributors  and/or  petroleum  companies  will  develop  refuelling  stations  to  meet 

projected  demand.    If  customers  are  unable  to  obtain  fuel  conveniently  and  affordably,  a  mass  market  for 

vehicles powered by our technology is unlikely to develop. 

Changes in Environmental and Regulatory Policies Could Hurt the Market for Our Products 

We currently benefit from, and hope to continue to benefit from, certain government environmental policies, 

mandates and  regulations  around the  world,  most significantly  in the  automotive markets and in the  United 

States.  Examples of such regulations include those that provide economic incentives, subsidies, tax credits 

and  other  benefits  to  purchasers  of  low  emission  vehicles,  restrict  the  sale  of  engines  that  don’t  meet 

emission standards, fine the sellers of non-compliant engines, tax the operators of diesel engines and require 

the use of more expensive ultra-low sulphur diesel fuel.  There can be no assurance that these regulations 

and  incentives  will  not  be  relaxed  or  abandoned  before  they  are  implemented,  materially  impacting  our 

competitive position. 

We Currently Face and Will Continue to Face Significant Competition 

Our  products  face  and  will  continue  to  face  significant  competition.  New  developments  in  technology  may 

negatively affect the development or sale of some or all of our products or make our products uncompetitive 

or  obsolete.  Other  companies,  many  of  which  have  substantially  greater  customer  bases,  businesses  and 

other  resources  than  us,  are  currently  engaged  in  the  development  of  products  and  technologies  that  are 

similar to, or may be competitive with, certain of our products and technologies. 

Competition for our products will come from current power technologies, from improvements to current power 

22 

 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

technologies and from new alternative power technologies, including other fuel systems.  Each of our target 

markets is currently serviced by existing manufacturers  with  existing customers  and suppliers using proven 

and  widely  accepted  technologies.    Additionally,  there  are  competitors  working  on  developing  technologies 

such as fuel cells, advanced batteries and hybrid battery/internal combustion engines in each of our targeted 

markets.  Each of these competitors has the potential to capture market share in various markets, which could 

have a material adverse effect on our position in the industry and our financial results.  For our products to be 

successful against competing technologies, especially diesel engines, they must offer advantages in one or 

more of these areas: emissions performance, fuel economy, engine performance, power density, engine and 

fuel system weight, and engine and fuel system price.  There can be no assurance that our products will be 

able to offer advantages in all or any of these areas. 

We Depend on Our Intellectual Property and Our Failure to Protect That Intellectual Property Could Adversely 

Affect Our Future Growth and Success 

Failure  to  protect  our  existing  and  future  intellectual  property  rights  may  result  in  the  loss  of  our  ability  to 

exclude  others  from  practicing  our  technology  or  our  own  right  to  practice  our  technologies.    If  we  do  not 

adequately ensure our freedom to use certain technology, we may have to pay others for rights to use their 

intellectual property, pay  damages for infringement or misappropriation and/or be enjoined from using such 

intellectual property.  Our patents do not guarantee us the right to practice our technologies if other parties 

own  intellectual  property  rights  that  we  need in  order to practice  such  technologies.    Our  patent position  is 

subject  to  complex  factual  and  legal  issues  that  may  give  rise  to  uncertainty  as  to  the  validity,  scope  and 

enforceability of a particular patent.  Accordingly, we cannot assure that: 

• any  of  the  rights  we  have  under  U.S.  patents  or  foreign  patents  owned  by  us  or  other  patents  that  third 

parties license to us will not be curtailed, for example through invalidation, circumvention, challenge, being 

rendered unenforceable or by license to others; 

• we were the first inventors of inventions covered by our issued patents or pending applications or that we 

were the first to file patent applications for such inventions; 

• any of our pending or future patent applications will be issued with the breadth of claim coverage sought by 

us, or be issued at all; 

• if we wish to use technology developed by a third party, or are found to be infringing third party patents, that 

we will be able to obtain licenses on acceptable terms, if at all;  

• our  competitors  will  not independently  develop  or patent  technologies  that  are substantially  equivalent or 

superior to our technologies; or 

• any of our trade secrets will not be learned independently by our competitors. 

23 

 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

In addition, effective patent, trademark, copyright and trade secret protection may be unavailable, limited or 

not applied for in certain foreign countries. 

We  also  seek  to  protect  our  proprietary  intellectual  property,  including  intellectual  property  that  may  not  be 

patented or patentable, in part by confidentiality agreements and, if applicable, inventors’ rights agreements 

with our strategic partners and employees.  We cannot assure that these agreements will not be breached, 

that we will have adequate remedies for any breach or that such persons or institutions will not assert rights to 

intellectual property arising out of these relationships. 

Certain of our intellectual property has been licensed to us on a non-exclusive basis from third parties who 

may also license such intellectual property to others, including our competitors.  If necessary or desirable, we 

may seek further licenses under the patents or other intellectual property rights of others.  However, we can 

give  no  assurances  that  we  will  obtain  such  licenses  or  that  the  terms  of  any  offered  licenses  will  be 

acceptable to us.  The failure to obtain a license from a third party for intellectual property we use at present 

could cause us to incur substantial liabilities and to suspend the manufacture, shipment of products or our use 

of processes requiring such intellectual property. 

We Could Become Engaged in Intellectual Property Litigation That May Negatively Affect Our Business 

While we are not currently engaged in any intellectual property litigation, we could become subject to lawsuits 

in  which  it  is  alleged  that  we  have infringed  the  intellectual property  rights  of  others  or  commence  lawsuits 

against others who we believe are infringing upon our rights. Our involvement in intellectual property litigation 

could  result  in  significant  expense  to  us,  adversely  affecting  the  development  of  sales  of  the  challenged 

product or intellectual property and diverting the efforts of our technical and management personnel, whether 

or not such litigation is resolved in our favour. In the event of an adverse outcome as a defendant in any such 

litigation, we may, among other things, be required to: 

• pay substantial damages; 

• cease the development, manufacture, use, sale or importation of products that infringe upon other patented 

intellectual property; 

• expend significant resources to develop or acquire non-infringing intellectual property; 

• discontinue processes incorporating infringing technology; or 

• obtain licenses to the infringing intellectual property. 

We  cannot  assure  that  we  would  be  successful  in  such  development  or  acquisition  or  that  such  licenses 

would be available upon reasonable terms.  Any such development, acquisition or license could require the 

expenditure of substantial time and other resources and could have a material adverse effect on our business 

24 

 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

and financial results. 

We May Have Difficulty Managing the Expansion of Our Operations 

We may require rapid growth in the number of our employees, the size of our physical facilities and the scope 

of our operations.  Such rapid expansion may place a significant strain on our senior management team and 

other  resources.    Difficulties  in  effectively  managing  the  budgeting,  forecasting  and  other  process  control 

issues  presented  by  such  a  rapid  expansion  could  harm  our  business,  prospects,  results  of  operations  or 

financial condition. 

We Could Lose or Fail to Attract the Personnel Necessary to Run Our Business 

Our success depends in large part on the ability of ourselves and that of our affiliates to attract and retain key 

management,  engineering,  scientific,  manufacturing  and  operating  personnel.    As  we  develop  additional 

capabilities  we  will  require  more  skilled  personnel.    Recruiting  personnel  for  the  alternative  fuel  industry  is 

highly  competitive.    Although  to  date  we  have  been  successful  in  recruiting  and  retaining  executive, 

managerial and technical personnel, there can be no assurance that we will continue to attract and retain the 

qualified personnel needed for our business.  The failure to attract or retain qualified personnel could have a 

material adverse effect on our business. 

We Have Foreign Currency Risk 

The majority of our revenue is in US dollars while many of our operating expenses, other than cost of sales, 

are in Canadian dollars.  Foreign exchange gains and losses are included in results from operations.  A large 

decline in the value of the US dollar relative to the Canadian dollar could impair revenues, margins and other 

financial results.  However, this risk is mitigated by US dollar expenses in CWI and CWI warranty balances, 

which are denominated in US dollars.  We have not entered into foreign exchange contracts to hedge against 

gains and losses from foreign currency fluctuations. 

If We Do Not Properly Manage Foreign Sales and Operations, Our Business Could Suffer 

We  expect  a  substantial  portion  of  our  future  revenues  will  be  derived  from  foreign  sales  and  we  operate 

where we may lack the expertise, local knowledge, or contacts.  Our international activities may be subject to 

inherent risks, including unexpected changes in government policies, trade barriers, difficulty in staffing and 

managing  foreign  operations, longer payment cycles, and  foreign exchange controls that  restrict  or  prohibit 

repatriation of funds.  As a result, if we do not properly manage foreign sales and operations, our business 

could  suffer.    We  mitigate  this  risk  by  partnering  with  knowledgeable  and  reputable  local  companies  and 

people and by making incremental investments. 

We May Not Realise the Anticipated Benefits from Investments or Acquisitions 

In connection with any investment or acquisition we make, there may be liabilities that we fail to discover or 

25 

 
 
 
Management’s Discussion and Analysis 
for the years ended March 31, 2006 and 2005 

that  we  are unable to  discover  (including  liabilities  arising from  non-compliance  with environmental  laws by 

prior owners) and for which we, as successor owner, may be responsible. 

In  addition,  acquisitions  often  result  in  difficulties  in  integration,  which  adversely  affect  our  results.    The 

integration  process  may  also  divert  the  attention  of,  and  place  significant  demands  on,  our  managerial 

resources, which may disrupt our current business operations.  As a result, we may fail to meet our current 

product development and commercialization schedules. 

We  Could  be  Liable  for  Environmental  Damages  Resulting  From  Our  Research,  Development  or 

Manufacturing Operations 

The  nature  of  our  business  and  products  expose  us  to  the  risk  of  harmful  substances  escaping  into  the 

environment,  resulting  in  personal  injury  or  loss  of  life,  damage  to  or  destruction  of  property  and  natural 

resource damage.  Depending on the nature of the claim, our current insurance policies may not adequately 

reimburse us for costs incurred in settling environmental damage claims, and in some instances, we may not 

be reimbursed at all.  Our business is subject to numerous laws and regulations that govern environmental 

protection  and  human  health  and safety.    These  laws  and  regulations have  changed  frequently in the  past 

and it is reasonable to expect additional and more stringent changes in the future.  Our operations may not 

comply with future laws and regulations, and we may be required to make significant unanticipated capital and 

operating expenditures.  If we fail to comply with applicable environmental laws and regulations, governmental 

authorities  may  seek  to  impose  fines  and  penalties  on  us  or  to  revoke  or  deny  the  issuance  or  renewal  of 

operating permits and private parties may seek damages from us.  Under those circumstances, we might be 

required to curtail or cease operations, conduct site remediation or other corrective action, or pay substantial 

damage claims. 

Our Products Use Inherently Dangerous, Flammable Fuels, Which Could Subject Our Business to Product 

Liability Claims 

Our  business  exposes  us  to  potential  product  liability  claims  that  are  inherent  in  natural  gas,  propane,  and 

hydrogen and products that use these gases.  Natural gas, propane, and hydrogen are flammable gases and 

therefore  potentially  dangerous  products.  We  also  produce  fuel  processors  that  generate  hydrogen  from 

certain  raw  fuels  such  as  natural  gas,  which  are  also  flammable.    Any  accidents  involving  our  products  or 

other  natural  gas,  propane,  or  hydrogen-based  products  could  materially  impede  widespread  market 

acceptance  and  demand  for  our  engines  and  fuel  systems.    In  addition,  we  may  be  held  responsible  for 

damages beyond the scope of our insurance coverage.  We also cannot predict whether we will be able to 

maintain our insurance coverage on acceptable terms.

AUDITORS’ REPORT TO THE SHAREHOLDERS 

We have audited the consolidated balance sheets of Westport Innovations Inc. as at March 31, 2006 
and 2005 and the consolidated statements of operations and deficit and cash flows for the years then 
ended.    These  financial  statements  are  the  responsibility  of  the  Company's  management.    Our 
responsibility is to express an opinion on these financial statements based on our audits. 

We  conducted  our  audits  in  accordance  with  Canadian  generally  accepted  auditing  standards.  
Those standards require that we plan and perform an audit to obtain reasonable assurance 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. 

In  our  opinion,  these  consolidated  financial  statements  present  fairly,  in  all  material  respects,  the 
financial  position  of  the  Company  as  at  March  31,  2006  and  2005  and  the  results  of  its  operations 
and  its  cash  flows  for  the  years  then  ended  in  accordance  with  Canadian  generally  accepted 
accounting principles.

WESTPORT INNOVATIONS INC. 
Notes to Consolidated Financial Statements 
(Expressed in Canadian dollars) 

Years ended March 31, 2006 and 2005 

1.  Nature of operations: 

Westport Innovations Inc. (the "Company") was incorporated under the Business Corporations Act (Alberta) 

on March 20, 1995. 

The  Company  is  involved  in  the  research,  development  and  commercialization  of  environmental 

technologies,  including  high-pressure  direct  injection  (“HPDI”)  combustion  technology  that  allows  diesel 

engines to operate on cleaner burning gaseous fuels such as natural gas without sacrificing performance or 

fuel economy. 

The  Company  entered  into  a  joint  venture  with  Cummins  Inc.  (“Cummins”)  on  March  7,  2001.    The  joint 

venture agreement was amended on December 16, 2003 (note 15).  The joint venture, Cummins Westport 

Inc.  (“CWI”),  develops,  supports  and  markets  a  comprehensive  product  line  of  low-emission,  high 

performance  engines  and  ancillary  products  using  proprietary  intellectual  property  developed  by  the 

Company and Cummins. 

These consolidated financial statements have been presented on a going concern basis, which assumes the 

realisation  of  assets  and  the  settlement  of  liabilities  in  the  normal  course  of  operations.    To  date,  the 

Company has financed its operations primarily by equity financing and margins on the sale of products and 

parts.  If the Company does not have sufficient funding from internal or external sources, it may be required 

to delay, reduce or eliminate certain research and development programs and forego acquisition of certain 

equipment.  Subsequent to March 31, 2006, the Company agreed to issue up to $22.1 million of convertible 

notes  and  entered  into  an  agreement  to  reorganize  one  of  its  wholly  owned  subsidiaries  (note 19).    This 

transaction is expected to realize at least $10 million in proceeds.  The future operations of the Company are 

dependent upon its ability to produce, distribute and sell an economically viable product to attain profitable 

operations. 

2.  Significant accounting policies: 

(a)  Basis of presentation: 

The  consolidated  financial  statements  include  the  accounts  of  the  Company,  its  wholly  owned 

subsidiaries and CWI.  Intercompany accounts and transactions have been eliminated. 

In  June  2003,  the  CICA  issued  Accounting  Guideline  15,  “Consolidation  of  Variable  Interest  Entities”, 

which applies to annual or interim periods beginning on or after November 1, 2004.  A Variable Interest 

Entity  (“VIE”)  is  any  type  of  legal  structure  not  controlled  by  voting  equity,  but  rather  by  contractual 

and/or other financial arrangements.  Interests in VIE’s are consolidated by the company if the company 

is the primary beneficiary.  The Company has identified CWI as a VIE and determined that the Company 

is  the  primary  beneficiary.    Accordingly,  the  Company  has  consolidated  CWI.    The  other  50%  interest 

held  by  Cummins  is  reflected  as  “Joint  Venture  Partner’s  share  of  income  from  joint  venture”  in  these 

consolidated financial statements. 

These financial statements are presented in accordance with Canadian generally accepted accounting 

principles.    Material  measurement  differences  between  these  principles  and  accounting  principles 

generally accepted in the United States are disclosed in note 20.

2.  Significant accounting policies (continued): 

(b)  Cash and cash equivalents: 

Cash and cash equivalents includes cash and term deposits with maturities of ninety days or less when 

acquired. 

(c)  Short-term investments: 

Short-term  investments,  consisting  principally  of  investment  grade  commercial  paper,  are  recorded  at 

cost plus accrued interest.  

(d)  Long-term investments: 

The Company accounts for long-term investments in entities which are not consolidated using the equity 

method to the extent that the Company has significant influence over the investee’s strategic operating, 

financing  and  investing  policies.    Under  the  equity  method,  the  Company’s  proportionate  share  of 

income or loss is included in the statement of operations and any dividends received are recorded as a 

reduction of the investment.  All other long-term investments are accounted for using the cost method, 

whereby income is recorded in the accounts only to the extent dividends are received during the year.   

All long-term investments are currently carried at cost. 

Long-term  investments  are  reduced  to  their  fair  value  only  to  the  extent  that  the  loss  in  value is other 

than temporary. 

(e)  Inventory: 

The Company’s inventory consists of CWI engine products.  Inventory is stated at the lower of cost, on a 

specific identification basis, or net realisable value. 

(f)  Equipment, furniture and leasehold improvements: 

Equipment,  furniture  and  leasehold  improvements  are  stated  at  cost.    Depreciation  is  provided  as 

follows: 

Assets 

Computer equipment and software 
Furniture and fixtures 
Machinery and equipment 
Leasehold improvements

In 2006, the Company revised its estimate of the useful life of its research and development machinery 

and  equipment  from  five  to  eight  years.  The  impact  of  this  change  in  estimate  resulted  in  lower 

depreciation expense for the year ended March 31, 2006 of $1,092,038.

2.  Significant accounting policies (continued): 

(g)  Research and development costs: 

Research  costs  are  expensed  as  incurred  and  are  recorded  net  of  government  funding  received  or 

receivable.  Development costs are deferred only if they meet certain stringent criteria generally related 

to technical feasibility, market definition and financing availability for future development; otherwise they 

are expensed as incurred.  Related investment tax credits reduce research and development expenses 

in  the  same  year  in  which  the  related  expenditures  are  charged  to  earnings,  provided  there  is 

reasonable  assurance  the  benefits  will  be  realised.   As at March 31, 2006 and 2005, no development 

costs had been deferred. 

(h)  Government assistance: 

The  Company  periodically  applies  for  financial  assistance  under  available  government  incentive 

programs which is recorded in the period it is received or receivable.  Government assistance relating to 

the purchase of equipment, furniture and leasehold improvements is reflected as a reduction of the cost 

of such assets.  Government assistance related to research and development activities is recorded as a 

reduction of the related expenditures. 

(i) 

Intellectual property: 

Intellectual property, consisting primarily of the cost of acquired patents, licenses and other intellectual 

property, is amortized over periods ranging from three to seven years.  

(j) 

Impairment of long-lived assets: 

The Company reviews for impairment of long-lived assets, including equipment, furniture, and leasehold 

improvements  and  intellectual  property,  to  be  held  and  used  whenever  events  or  changes  in 

circumstances  indicate  that  the  carrying  amount  of  the  assets  may  not  be  recoverable.    If  such 

conditions  exist,  assets  are  considered  impaired  if  the  sum  of  the  undiscounted  expected  future  cash 

flows  expected  to  result  from  the  use  and  eventual  disposition  of  an  asset  is  less  than  its  carrying 

amount.    An  impairment  loss  is  measured  at  the  amount  by  which  the  carrying  amount  of  the  asset 

exceeds its fair value.  When quoted market prices are not available, the Company uses the expected 

future cash flows discounted at a rate commensurate with the risks associated with the recovery of the 

asset as an estimate of fair value.

Years ended March 31, 2006 and 2005 

2.  Significant accounting policies (continued): 

(k)  Warranty liability: 

Estimated warranty costs are recognised at the time CWI sells its products, and are included in cost of 

revenue.  CWI provides warranty coverage on its products sold for a period of two years from the date 

the  products  are  put  into  service  by  customers.    Warranty  liability  represents  CWI’s  best  estimate  of 

warranty costs expected to be incurred during the warranty period.  Furthermore, the current portion of 

warranty  liability  represents  CWI’s  best  estimate  of  the  costs  to  be  incurred  in  the  next  twelve  month 

period.  CWI uses historical failure rates and cost to repair defective products together with information 

on known product issues to estimate the warranty liability.  The ultimate amount payable by CWI and the 

timing will depend on actual failure rates and cost to repair failures of its products.  Since many of CWI’s 

products  are  new  in  the  market,  historical  data  may  not  necessarily  reflect  actual  costs  to  be incurred 

and exposes CWI to the potential for significant fluctuations in the warranty liability. 

(l)  Revenue recognition: 

Product  and  parts  revenue  is  recognised,  net  of  estimated  costs  of  returns,  allowances,  and  sales 

incentives,  when  the  products  are  shipped  and  title  passes  to  the  customers.    Shipments  of  most 

products and parts sold by CWI originate from Cummins’ facilities.  Revenue also includes fees earned 

from  performing  research  and  development  activities  for  third  parties.    Revenue  from  research  and 

development  activities  is  recognised  as  the  services  are  performed.    Amounts  received  in  advance  of 

revenue recognition are recorded as deferred revenue. 

(m)  Income taxes: 

The Company uses the asset and liability method of accounting for income taxes.  Under this method, 

future  income  tax  assets  and  liabilities  are  determined  based  on  temporary  differences  between  the 

accounting  and  tax  basis  of  the  assets  and  liabilities  and  for  loss  carry  forwards,  and  are  measured 

using the tax rates expected to apply when these tax assets and liabilities are recovered or settled.  The 

effect on future tax assets and liabilities of a change in tax rate is recognised in income in the period that 

includes the substantive enactment date.  A valuation allowance is recorded against any future income 

tax asset if it is not “more likely than not” that the benefit of these assets will be realised. 

(n)  Stock-based compensation plans: 

The  Company  accounts  for  stock-based  compensation  related  to  stock  options  granted  to  employees 

and directors using the fair value method and recognised as stock-based compensation in results from 

operations  over  the  vesting  period.    The  Company  has  an  employee  share  purchase  plan,  which  is 

described in note 11(e).  The Company matches the employees’ contribution and recognizes this cost 

as an expense in the period it is incurred. 

The Company has a Performance Share Unit (“PSU”)  Plan as described in note 12.  The value of the 

units is calculated based on the market price of the Company’s common shares on the date of grant and 

is recorded as compensation expense in the period earned, which generally is the period over which the 

PSU’s vest.

Years ended March 31, 2006 and 2005 

2.  Significant accounting policies (continued): 

(o)  Financial Instruments: 

Effective  for  the  Company’s  fiscal  year  beginning  April  1,  2005,  the  Company  adopted  amended 

Handbook Section 3860 - “Financial Instruments - Disclosure and Presentation” (“HB 3860”) related to 

financial instruments that are contractual obligations of a fixed amount but are settleable with a variable 

number  of  the  Company’s  common  shares.  Amendments  to  HB  3860  require  that  these  financial 

instruments be classified as liabilities rather than shareholders’ equity because they do not represent a 

residual interest in the Company until the common shares are issued.  Accordingly, the value assigned 

to  the  Technology  Partnerships  Canada  (“TPC”)  warrants  and  the  GVH  Entwicklungsgesellschaft  für 

Verbrennungsmotoren und Energietechnik mbH (“GVH”) obligation to issue shares, both of which were 

included  in  “Other  Equity  Instruments”  in  fiscal  2005,  are  in  substance  a  liability  to  the  Company 

because the number of common shares to be issued is determined based on a fixed contractual amount 

of fair value due to TPC and the vendors of GVH. These fixed contractual amounts will be settled using 

equity instruments with the number of such instruments to be determined based on the market value of 

the Company’s common shares on the date these instruments are settled. Accordingly, these amounts 

have been reclassified as liabilities and prior period financial statements have been reclassified to reflect 

this change in accounting policy. 

(p)  Post-retirement benefits: 

The Company has implemented a group registered retirement savings plan (“RRSP”) in which full-time 

employees of the Company are eligible to participate.  Eligible employees may make contributions up to 

their personal eligible contribution room under the Canadian Income Tax Act.  The Company contributes 

up  to  a  maximum  combined  total  of  5%  of  the  employee’s  regular  base  pay  to  the  RRSP  and/or  the 

employee  share  purchase  plan  and  recognizes  this  cost  as  an  expense  in  the  period  it  is  incurred.  

During  the  year  ended  March  31,  2006,  the  Company  recognised  $317,113  (2005  -  $156,971)  of 

expense associated with the RRSP. 

(q)  Foreign currency: 

The Company and its subsidiaries located outside of Canada, including CWI, are treated as integrated 

operations with the Canadian dollar as their functional currency.  Monetary items denominated in foreign 

currency are translated into Canadian dollars at exchange rates in effect at the balance sheet date and 

non-monetary  items  are  translated  at  rates  of  exchange  in  effect  when  the  assets  were  acquired  or 

obligations  incurred.    Revenue  and  expenses  are  translated  at  rates  in  effect  at  the  time  of  the 

transactions.  Foreign exchange gains and losses are included in results from operations. 

(r)  Use of estimates: 

The preparation of financial statements requires management to make estimates and assumptions that 

affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the 

financial statements, and the reported amounts of revenue and expenses during the period.  Significant 

areas  requiring  the  use  of  estimates  include  amortization  of  equipment,  furniture  and  leasehold 

improvements,  the  determination  of  future  cash  flows  and  discount  rates  for  impairment  of  long-lived 

assets,  valuation  of  long-term  investments  and  the  accrual  of  warranty  liability.    Actual  results  could 

differ from estimates used in the preparation of the consolidated financial statements.

2.  Significant accounting policies (continued): 

(s)  Loss per share: 

Basic loss per share is calculated using the weighted average number of shares outstanding during the 

period.    Diluted loss per share is computed similarly to basic loss per share, except that the weighted 

average  shares  outstanding  are  increased  to  include  additional  shares  from  the  assumed  exercise  of 

stock  options,  warrants,  and  performance  share  units,  if  dilutive.    The  number  of  additional  shares  is 

calculated  by  assuming  that  outstanding  stock  options,  warrants,  and  performance  share  units  were 

exercised at the beginning of the year or when granted and that the proceeds from such exercises were 

used to repurchase shares of common stock at the average market price during the period. 

(t)  Comparative amounts: 

Certain  comparative  amounts  have  been  reclassified  to  conform  with  the  presentation  adopted  in  the 

current year. 

3.  Long-term investments: 

The Company owns 8.14% (2005 - 10%) interest in Clean Energy Fuels Corp., a private Company that is an 

owner and operator of natural gas refueling facilities, and is carried at a cost of $9,133,876.  In March 2005 

the  Company’s  investment  in  Edge  Technologies  Inc.  was written off as the Company determined that the 

decline in value was other than temporary.

8.  Long-term debt and other long-term obligations (continued): 

(a)  The  Company  has  capital  lease  obligations  which  have  terms  of  two  to  five  years  at  interest  rates 

ranging  from  1.15%  to  6.17%.    The  capital  lease  obligations  require  the  following  minimum  annual 

payments during the respective fiscal years:

(b)  As at March 31, 2005, other debt obligations consisted of long-term bank indebtedness bearing interest 

at a rate of 4.25% and secured by a term deposit of 415,000 Euros.  In 2006, the debt obligation was 

fully repaid. 

(c)  The  Company  renegotiated  its  existing  long-term  lease  agreements  for  its  corporate  offices  and 

research  facilities  in  2004  and  2005  which  included  certain  lease  inducements.    These  inducements 

included leasehold improvements and other costs funded by the lessor and periods with reduced rental 

payments.    The  amounts  related  to  leasehold  improvements  funded  by  the  lessor  are  amortized  on  a 

straight-line basis over the term of the lease as a reduction to rent expense.  For lease contracts with 

escalating  lease  payments,  total  rent  expense  for  the  lease  term  is  expensed  on  a  straight  line  basis 

over the lease term.  The difference between amounts expensed and amounts paid is recorded as an 

increase or reduction in deferred lease inducements. 

9.  Government assistance: 

From time to time, the Company enters into agreements for financial assistance with government agencies.  

During  the years ended March 31, 2006 and 2005, government assistance of $8,689,159 and $5,978,930, 

respectively, was received or receivable by the Company, which has been recorded as a reduction of related 

research and development expenditures (note 13).

Canada  (“TPC”),  of  which  $1,574,450  is  included  in  accounts  receivable  at  March 31,  2006  (2005  - 

$1,210,438).  Under the terms of the TPC funding agreement entered into on March 27, 2003, TPC will fund 

30% of the eligible costs of, among other research projects, the adaptation of the Company’s technology to 

diesel engines.  From fiscal 2007 to fiscal 2013, inclusive, the Company is obligated to pay annual royalties 

equal  to  the  greater  of  $1,350,000  or  0.33%  of  the  Company’s  annual  gross  revenue  from  all  sources, 

provided  that  gross  revenue  exceed  $13,500,000  in  any  of  the  aforementioned  fiscal  years.    The  royalty 

period may be extended until the earlier of March 31, 2016 or until cumulative royalties total $28,189,000.  In 

addition,  on  September  30,  2006,  the  Company  is  required  to  provide  TPC  with  common  share  purchase 

warrants  having  a  value  of  $4,000,000  calculated  based  on  the  Black-Scholes  option  pricing  model.    The 

value  of  the  warrants  is  being  accreted  on  a  straight-line  basis  to  September  30,  2006  as  a  charge  to 

research and development expenses.

Resources  and  British  Columbia’s  Green  Economy  Development  Fund  relating to funding received in prior 

years.  The royalty to the Department of Natural Resources is 1% of future revenue from engines for power 

generators  until  the  earlier  of  ten  years  from  the  project  completion  date  (August  30,  2004)  or  when

expected  life  of  options  -  5  years  (2005  -  4  years).    The  weighted  average  grant  date  fair  value  was 

$0.87  for  options  granted  for  the  year  ended  March  31,  2006  (2005  -  $1.11).    During  the  year  ended

11.  Share capital (continued): 

(e)  Employee share purchase plan: 

The Company has an employee share purchase (“ESPP”) in which full-time employees of the Company 

are eligible to participate.  Eligible employees may make contributions to the ESPP of up to 10% of their 

regular base pay.  The Company contributes up to a maximum combined total of 5% of the employee's 

regular base pay to the RRSP and/or the ESPP.  Shares contributed to the ESPP are purchased by the 

Company on a semi-monthly basis on the open market.  Shares purchased on behalf of the employee 

with  the  employee’s  contribution  vest  with  the  employee  immediately.    Shares  purchased  with  the 
Company’s contribution vest on December 31st of each year, so long as the employee is still employed 
with the Company. 

(f)  Loss per share: 

Diluted  loss  per  share  does  not  differ  from  basic  loss  per  share  as  the  impact  of  dilutive  securities, 

including all stock options, warrants, and performance share units, is anti-dilutive. 

12.  Other equity instruments: 

Other  equity  instruments  consists  of  the  value  assigned  to  performance  share  units  (“Units”)  granted 

pursuant to the Company’s 2003 Performance Share Unit Plan (“2003 Unit Plan”). 

At the Company's 2003 annual general meeting, the shareholders of the Company ratified and approved the 

2003  Performance  Share  Unit  Plan  (the  “2003  PSU  Plan”)  and  reserved  2,500,000  common  shares  under 

this  plan.    The  2003  PSU  Plan  is  in  addition  to  the  Performance  Share  Unit  Plan  approved  by  the 

shareholders on September 10, 2001 (the “2001 PSU Plan”).  Each unit (“PSU”) issued pursuant to the 2003 

PSU  Plan  or  the  2001  PSU  Plan  is  exercisable  into  one  common  share  of  the  Company  for  no  additional 

consideration.  Any employee, contractor, director or executive officer of the Company who is selected by the 

Board of Directors of the Company is eligible to participate in the 2003 PSU Plan.  The Executive Plan sets 

out  provisions  where  the  PSU’s  will  be  granted  to  the  Company’s  executive  management  if  performance 

milestones  are  achieved  as  determined  at  the  discretion  of  the  Human  Resources  and  Compensation 

Committee  of  the  Company’s  Board  of  Directors  in  consultation  with  the  Company’s  management.    These 

performance  milestones  are  focused  on  achievement  of  key  cash  management,  profitability  and  revenue 

growth objectives.  Vesting periods for each PSU granted pursuant to the 2003 PSU Plan is at the discretion 

of the Board of Directors and may include time based, share price or other performance targets. 

The value assigned to issued PSU’s and the amounts accrued are recorded as other equity instruments.  As 

PSU’s  are  exercised  and  the  underlying  shares  are  issued  from  treasury  of  the  Company,  the  value  is 

reclassified to share capital.  During the year ended March 31, 2006, the Company recognised $1,082,158 

(2005 - $1,359,620) of stock-based compensation associated with the 2001 PSU Plan and 2003 PSU Plan.

In  determining  the  valuation  allowance,  management  considers  whether  it  is  more  likely  than  not  that 

some  portion  or  all  of  the  future  tax  assets  will  not  be  realised.    The  ultimate  realisation  of  future  tax 

assets  is  dependent  on  the  generation  of  income  during  the  future  periods  in  which  those  temporary 

differences become deductible.  Since evidence does not exist that the future income tax assets will be 

fully realised, a valuation allowance has been recorded.

15.  Investment in Cummins Westport Inc.: 

The  Company  entered  into  a  joint  venture  with  Cummins  on  March  7,  2001.    The  joint  venture,  CWI,  was 

formed  to  explore  a  range  of  product  and  technology  opportunities  using  natural  gas  as  the  primary  fuel.  

The Company provided personnel, financing and key technologies for the venture, while Cummins provided 

an existing product line, manufacturing, product distribution and customer service functions, as well as key 

management and engineering personnel.  

From inception until December 31, 2003, the Company was responsible for all capital contributions to fund 

operations.    Initially  and  to  December  31,  2003,  the  Company  owned  100%  of  the  common  shares  and 

Cummins owned 100% of the non-participating preferred shares which were convertible into common shares 

for no consideration at the option of Cummins.

15.  Investment in Cummins Westport Inc. (continued): 

On  December  16,  2003,  the  Company  and  Cummins  amended  the  joint  venture  agreement  to  have  CWI 

focus  on  and  develop  markets  for  alternative  fuel  engines.    In  addition,  the  two  companies  signed  a 

Technology  Partnership  Agreement  that  creates  a  flexible  arrangement  for  future  technology  development 

between Cummins and the Company.  Under the terms of the amended joint venture agreement, Cummins 

exercised the conversion feature of the preferred shares effective January 1, 2004.  However, the Company 

remained responsible for funding the profit and loss of CWI through CWI’s fiscal 2004 year which ran from 

January  1  to  December  31,  2004.    Based  on  its  economic  interest  in  CWI,  the  Company  continued  to 

consolidate 100% of the results of operations from CWI until December 31, 2004. 

From  January  1,  2005  forward,  Cummins  shares  equally  in  the  profits  and  losses  of  CWI.    However,  the 

Company  has  determined  that  CWI  is  a  VIE  and  that  the  Company  is  the  primary  beneficiary  as  the 

Company’s  variable  interests  in  CWI,  comprising  of  its  equity,  debt  and  royalty  interests,  will  absorb  more 

than 50% of the expected losses of CWI and that CWI’s business activities are more integral to those of the 

Company.  Accordingly, the Company continues to consolidate CWI with Cummins’ share of CWI’s income 

and losses included as “Joint Venture Partner’s share of income from joint venture”.   

Assets, liabilities, revenue and expenses of CWI as at and for the periods presented are as follows: 

Current assets: 

Cash and cash equivalents 
Accounts receivable 
Inventory 
Prepaid expenses 

Equipment, furniture and leasehold improvements 

Current liabilities: 

Accounts payable and accrued liabilities 
Deferred revenue 
Current portion of warranty liability 

Long term liabilities:

17.  Financial instruments: 

(a)  Fair values: 

The  carrying  amounts  reported  in  the  balance  sheets  for  cash  and  cash  equivalents,  short-term 

investments,  accounts  receivable,  and  accounts  payable  and  accrued  liabilities  approximate  their  fair 

values,  due  to  the  short  terms  to  maturity  of  these  instruments.    The  carrying  value  of  the  warranty 

obligation represents management’s best estimate of its fair value. 

The  carrying  value  reported  in  the  balance  sheets  for  obligations  under  capital  lease,  which  is  based 

upon  discounted  cash  flows,  approximates  its  fair  value.    The  fair  value  of  the  Company’s  demand 

instalment  loan  and  other  long-term  debt  obligations  is  not  materially  different  from  its  carrying  value 

based on market rates of interest. 

The fair value of the Company’s financial instruments as described in note 10 represent management’s 

best estimate of its fair value. 

The fair value of the Company’s long-term investments in Clean Energy Fuels Corp, a private company, 

as  described  in  note 3  is  not  determinable  with  sufficient  reliability  due  to  the  absence  of  a  readily 

available market for the shares of these investees. 

(b)  Concentrations of credit risk: 

The  Company  is  exposed  to  credit  risk  only  with  respect  to  uncertainties  as  to  timing  and  amount  of 

collectability  of  accounts  receivable.    57%  (2005  -  58%)  of  accounts receivable  relates  to  government 

grants  receivable  and  38%  (2005  -  25%)  is  due  from  Cummins  relating  to  proceeds  for  the  sale  of 

products collected by Cummins on the Company’s behalf. 

(c)  Foreign currency risk: 

Foreign currency risk is the risk to the Company’s results from operations that arises from fluctuations in 

foreign currency exchange rates.  All of the revenue realised and a significant portion of the expenses 

incurred  by  CWI,  and  recorded  by  the  Company,  are  denominated  in  United  States  dollars.    The 

warranty  liability  is  also  denominated  in  United  States  dollars.    The  Company  has  not  entered  into 

foreign exchange contracts to hedge against gains and losses from foreign currency fluctuations. 

18.  Segmented information: 

The  Company  currently  operates  in  one  operating  segment  which  involves  the  research  and  development 

and the related commercialization of engines and fuel systems operating on gaseous fuels.  The majority of 

the  Company’s  equipment,  furniture  and  leasehold  improvements  are  located  in  Canada.    For  the  year 

ended March 31, 2006, 82% (2005 - 61%) of the Company’s revenue was from sales in North America, 4% 

(2005 - 24%) from sales in China, and 14% (2005 - 15%) from sales elsewhere.

19.  Subsequent events: 

On  June  12,  2006,  the  Company  agreed  to  issue  up  to  $22.1  million  in  five  year  secured,  subordinated 

convertible  notes  with  a  coupon  rate  of  8%  to  Perseus,  L.L.C.  (“Perseus”)  of  Washington,  DC,  a  private 

equity fund management group.  The notes are to be issued in two tranches of $13.8 million and $8.3 million, 

respectively.  Interest will be payable semi-annually in arrears in additional convertible notes or shares at the 

option of the Company for the first two years.  After the first two years, interest will be calculated at a rate of 

8% on the outstanding principal amount only for the number of trading days in the period on which the share 

price  of  the  Company’s  common  shares  is  below  $3.00  and  is  payable  semi-annually  in  cash,  additional 

convertible notes or shares at the option of the Company.  The first tranche is convertible to common shares 

at a conversion price of $1.30 at any time during the term of the notes and the second tranche is convertible 

to common shares at a conversion price of $1.40.  At the time of issuance, the note holder will also receive 

warrants to acquire, at an exercise price equal to the conversion price of the accompanying notes, common 

shares of the Company equal to 25% of the number of common shares into which the notes are convertible.  

The  term  to  expiry  of  the  warrants  is  four  years  from  the  date  of  issuance  and  the  warrants  include  a 

cashless  exercise  provision  which  would  allow  the  note  holder  to  receive  the  number  of  common  shares 

having  a  value  equal  to  the  net  gain  that  would  be  realized  by  the  note  holder  if  the  warrants  had  been 

exercised  for  cash  and  the  related  shares  sold  at  the  market  price on the date  the warrants are exercised 

under  the  cashless  exercise provision.  Any warrants converted under the cashless exercise option will be 

cancelled.    For  so  long  as  Perseus  continues  to  hold  notes  and  warrants  convertible  into  a  specified 

percentage of the Company's issued and outstanding shares, Perseus will also be entitled to nominate two 

of seven board seats.  The notes will be secured with a second charge on all of the Company’s assets. 

$5.5  million  of  the  first  tranche  of  $13.8  million  has  been  received  with  the  balance  due  by  July  15,  2006.  

The  second  tranche  of  $8.3  million,  the  proceeds  of  which  are  to  be  used  for  a  new  business  venture,  is 

subject to receiving Company shareholder approval and the Company meeting certain milestones within 180 

days of the receipt of such shareholder approval.  

On  June  13,  2006,  the  Company  also  entered  into  an  agreement  with  Matco  Capital  Ltd.  (“Matco”)  to 

reorganize Westport Research Inc. (“WRI”), a wholly owned subsidiary of the Company.  The Company will 

transfer all of the assets, liabilities and operations of WRI to other wholly owned subsidiaries.  Matco will then 

acquire a 45% equity interest in WRI from the Company, following which the Company and Matco will source 

and  pursue  other  opportunities  to  maximize  the  value  of  their  respective  interests  in  WRI.    The 

reorganization  and  share  sale  is  expected  to  close  on  or  before  July  31,  2006.   The  Company  expects  to 

access at least $10 million in cash on closing with the ultimate amount to be determined by the value of the 

reorganized WRI, including any new ventures.

Notes to Consolidated Financial Statements 
(Expressed in Canadian dollars) 

Years ended March 31, 2006 and 2005 

20.  United States generally accepted accounting principles: 

These  consolidated  financial  statements  have  been  prepared  in  accordance  with  generally  accepted 

accounting  principles  in  Canada  ("Canadian  GAAP")  which  differ  in  certain  respects  with  accounting 

principles  generally  accepted  in  the  United  States  ("US  GAAP").    Material  issues  that  could  give  rise  to 

measurement differences to these consolidated financial statements are as follows: 

(a)  Income taxes: 

Under  both  Canadian  and  United  States  GAAP,  future  income  tax  assets  and  liabilities  are  measured 

using the income tax rates and income tax laws that, at the balance sheet date, are expected to apply 

when  the  assets  are  realised  or  the  liabilities  are  settled.    In  Canada,  announcements  of  changes  in 

income tax rates and tax laws by the government can have the effect of being substantially enacted at 

the balance sheet date even though they are not yet proclaimed into law.  When persuasive evidence 

exists  that  the  government  is  able  and  committed  to  enacting  proposed  changes  in  the  foreseeable 

future, the substantively enacted rate is used to measure the future tax assets and liabilities.  Under US 

GAAP,  only  the  income tax rates and income tax laws enacted at the balance sheet date are used to 

measure  the  future  income  tax  assets  and  liabilities.    For  the  years  ended  March 31,  2006  and  2005, 

enacted rates for US GAAP purposes were equal to rates used for Canadian GAAP purposes. 

(b)  Investments in securities: 

For  US  GAAP  purposes, 

the  Company's  short-term 

investments  would  be  classified  as 

"available-for-sale"  securities.    This  requires  that  unrealised  gains  and  losses  be  recognised  as  a 

separate component in shareholders' equity.  As described in note 17(a), the fair value of the short-term 

investments is not materially different from carrying value and no adjustment is required. 

(c)  Stock-based compensation: 

As described in note 11(d), the Company has granted share options to certain directors, consultants and 

employees.  These options are granted for services provided to the Company.  Effective April 1, 2004, 

the  Company  changed  its  accounting  policy  for  recognising  stock-based  compensation  for  US  GAAP 

purposes  from  the  intrinsic  value  method  to  the  fair  value  method  using  the  transition  provisions  of 

Statement  of  Financial  Accounting  Standard  No.  148,  Accounting  for  Stock-Based  Compensation  - 

Transition  and  Disclosure  (“SFAS  148”).    As  permitted  by  SFAS  148,  the  Company  adopted  the  fair 

value  method  retroactively  without  restatement  using  the  modified  prospective  method.    However,  for 

Canadian  GAAP,  only  options  granted  on  or  after  April  1,  2002  are  accounted  for  using  the  fair  value 

method and a cumulative adjustment is made to deficit for stock based compensation that would have 

been recognised prior to April 1, 2004 had the Company always applied the fair value method.  For U.S. 

GAAP  purposes,  all  options  granted  subsequent  to  December  15,  1995  would  have  been  measured 

using  the  fair  value  method  but,  for  the  Company,  only  the  effect  of  those  options  outstanding  and 

unvested as of April 1, 2004 on the results from operations in the year in which SFAS 148 is adopted 

would  be  recognised.    Accordingly,  on  adoption  of  the  fair  value  method  for  US  GAAP  purposes, 

adjustments  to  deficit  of  $2,493,153,  share  capital  of  $67,753,  and  additional  paid  in  capital  of 

$2,425,400 recognized for Canadian GAAP purposes would not have been made.  In addition, for US 

GAAP purposes in years prior to 2005, the Company would have recognised stock-based compensation 

of $2,164,551 relating to stock options issued to non-employees prior to April 1, 2002.

20.  United States generally accepted accounting principles (continued): 

(c)  Stock-based compensation (continued): 

Under  US  GAAP,  an  additional  $210,698  would  have  been  recognized  prior  to  2005  as  a  result  of 

certain option modifications. 

(d)  Research and development costs: 

For  US  GAAP  purposes,  research  and  development  costs  are  expensed  as  incurred.    In  these 

consolidated financial statements, intellectual property, consisting mainly of the cost of acquired patents, 

licenses and intellectual property acquired on business combinations in prior years, is considered to be 

used  in  research  and  development  activities  and  would  be  expensed  as  incurred  under  US  GAAP.  

Accordingly, amortization of intellectual property recorded under Canadian GAAP, would not be required 

to be recognised under U.S. GAAP. 

(e)  Restructuring and write down of equipment, furniture and leasehold improvements: 

For US GAAP purposes, write-down of equipment, furniture and leasehold improvements of $402,966 in 

2005 would be included in cost of revenue and expenses. 

(f)  Effect of US GAAP differences:
