L E T T E R TO U N I T H O L D E R S

2001 Annual Report

In times of economic uncertainty, it takes discipline to stay focused on your goals and carry out your
strategy. That’s exactly what TC PipeLines did in 2001. We are pleased to report that TC PipeLines has
again met its objective of delivering stable cash distributions to unitholders as a result of disciplined
adherence to our business strategy. In many respects, 2001 was a year like no other. It has become clear
to us that the drive to grow a business must be predicated on sound business fundamentals and carried
out with rigor. Growth without these characteristics cannot ultimately be sustained. 

FOCUS ON STRATEGY
Since our initial public offering in May 1999, our strategy has remained constant – focus on natural gas transmission assets
that connect growing demand for natural gas with growing supply of natural gas, and possess organic growth potential. By
adhering to this strategy, TC PipeLines was able to increase 2001 cash distributions paid to unitholders by almost 7% com-
pared to 2000. This marked our second distribution increase since we began operations in May 1999. The increase in cash
distributions is supported by the continuing strong cash flows being generated by our 30% investment in Northern Border
Pipeline Company and our 49% investment in Tuscarora Gas Transmission Company.

We believe Northern Border Pipeline and Tuscarora possess the characteristics that result in the kind of predictable,
sustainable  cash  flows  with  moderate  growth  potential  desired  by  our  unitholders. Both  assets  have  experienced  recent
growth that has resulted in increased value to our unitholders. Project 2000, which was completed in October 2001, extends
Northern Border’s pipeline system into northern Indiana and provides access to this new and growing market for natural
gas. Project 2000 also increased Northern Border Pipeline’s delivery capacity into the important Chicago market by 30%.
The Hungry Valley lateral, completed in January 2001, in conjunction with an increase in inlet pressure, allowed Tuscarora
to increase its delivery capability into Reno, Nevada by approximately 14%. Both projects are supported by contracts rang-
ing from 10 to 15 years and strengthen Northern Border Pipeline’s and Tuscarora’s abilities to continue generating stable
cash flows. These projects also demonstrate that the two pipeline systems are well positioned to meet the growing demand
for natural gas in their respective markets.

Demand for natural gas in the North American marketplace is growing, and we expect this trend to continue. Over
the next decade, we expect demand in the west, the market served by Tuscarora, and demand in the midwest, the market
served  by  Northern  Border  Pipeline, to  increase. Consistent  with  the  North  American  natural  gas  market  in  general,
approximately half of the forecasted growth in these markets is expected to be driven by the power generation sector. The
remainder of the growth is expected to come from increased industrial, commercial and residential demand. Projected
demand, coupled with Northern Border Pipeline’s and Tuscarora’s strong competitive positions, leads us to expect these
pipelines will continue to operate at high utilization rates.

In order to feed this demand, the supply of natural gas must keep pace. Both pipelines draw their supply from the west-
ern Canadian sedimentary basin, one of North America’s largest sources of natural gas. We expect gas exploration activity
to remain high as focus shifts to the north and west areas of the WCSB, with production expected to continue to increase.

FUTURE GROWTH
We expect our next phase of growth will come from Tuscarora’s mainline expansion, which will almost double
Tuscarora’s current capacity of 127 million cubic feet per day. As with Project 2000 and the Hungry Valley later-
al, this  expansion  is  supported  with  long-term  gas  transportation  contracts  with  terms  ranging  from  10  to  15
years. The first phase of the Tuscarora expansion is expected to be completed by November 2002, and the second
phase is expected to be in service by the end of 2003.

TC PipeLines continues to look for opportunities to grow the Partnership through acquisitions. Our focus is
on acquiring high quality assets in the northern tier of North America where we will be able to generate value
through synergies with either our existing assets or with the assets of TransCanada PipeLines Limited, the parent
of our general partner. The recent weakness in the energy sector has caused some energy companies to look for
ways to strengthen their balance sheets. We believe this may lead to opportunities to acquire natural gas pipelines
at prices that will add long-term value to TC PipeLines. We continually evaluate opportunities for acquisitions on
commercially attractive terms that are accretive to our unitholders. Our goal remains that of adding assets that
are accretive to cash flow and allow us to maintain our low-risk profile.

STRONG FINANCIAL POSITION
The strength of our financial position further underlines our disciplined approach to growth. We take great pride
in our healthy balance sheet and believe it will enable TC PipeLines to access capital quickly, be it through debt or
equity, when an opportunity arises.

In conclusion, TC PipeLines has had another successful year. We look forward to continuing to build on that
success  in  the  years  to  come. Through  our  continued  focus  on  maintaining  stability  and  pursuing  attractive
growth opportunities we are committed to delivering sustainable value for our unitholders.

PART I

ITEM 1. BUSINESS

Business of TC PipeLines, LP
TC PipeLines, LP was formed in 1998 as a Delaware limited partnership to acquire, own and participate in the man-
agement of United States based pipeline assets. TC PipeLines, LP and its subsidiary limited partnerships, TC PipeLines
Intermediate  Limited  Partnership  and  TC  Tuscarora  Intermediate  Limited  Partnership  are  collectively  referred  to
herein  as “TC  PipeLines” or “the  Partnership.” TC  PipeLines  GP, Inc., a  wholly  owned  subsidiary  of TransCanada
PipeLines Limited, is the general partner of the Partnership.

The Partnership owns a 30% general partner interest in Northern Border Pipeline Company. The remaining 70%
general partner interest in Northern Border Pipeline is held by Northern Border Partners, L.P., a publicly traded lim-
ited partnership not affiliated with TC PipeLines that is controlled by affiliates of Enron Corp.

As of September 1, 2000, TC PipeLines, also owns a 49% general partner interest in Tuscarora Gas Transmission

Company. The Partnership acquired this asset from TCPL Tuscarora Ltd., an indirect subsidiary of TransCanada.

The general partner holds an aggregate 2% general partner interest in the Partnership. The general partner also
owns 2,809,306 subordinated units and is entitled to incentive distribution rights if quarterly cash distributions on the
common  and  subordinated  units  exceed  levels  specified  in  the  partnership  agreement  (see  Item  5. “Market  for
Registrant’s Common Units and Related Security Holder Matters”).

At December 31, 2001, the Partnership had 14,690,694 common units outstanding, of which 11,890,694 are held

by the public and 2,800,000 are held by an affiliate of the general partner.

The Partnership’s 30% general partner interest in Northern Border Pipeline and 49% general partner interest in

Tuscarora represent its only material assets.

Business of Northern Border Pipeline Company
General
Northern Border Pipeline is a general partnership formed in 1978. Northern Border Pipeline’s general partners are TC
PipeLines and Northern Border Partners, both of which are publicly traded limited partnerships. Each of TC PipeLines
and Northern Border Partners holds its interest in Northern Border Pipeline, representing 30% and 70% of voting
power, respectively, through a subsidiary limited partnership. The general partner of TC PipeLines and its subsidiary
limited partnerships is TC PipeLines GP, Inc., a subsidiary of TransCanada. The general partners of Northern Border
Partners  and  its  subsidiary  limited  partnership  are  Northern  Plains  Natural  Gas  Company  and  Pan  Border  Gas
Company, both  subsidiaries  of Enron, and  Northwest  Border  Pipeline  Company, a  subsidiary  of The  Williams
Companies, Inc.

Northern  Border  Pipeline  owns  an  interstate  pipeline  system  that  transports  natural  gas  from  the  Montana-
Saskatchewan border to natural gas markets in the midwestern United States. The Northern Border pipeline system
connects with multiple pipelines that provide shippers with access to the various natural gas markets served by those
pipelines. In the year ended December 31, 2001, TC PipeLines estimates that Northern Border Pipeline transported
approximately 20% of the total amount of natural gas imported from Canada to the United States. Over the same period,
approximately 90% of the natural gas transported was produced in the western Canadian sedimentary basin located
in the provinces of Alberta, British Columbia and Saskatchewan.

Northern  Border  Pipeline  transports  natural  gas  for  shippers  under  a  tariff regulated  by  the  Federal  Energy
Regulatory Commission (FERC). The tariff specifies the calculation of amounts to be paid by shippers and the general
terms and conditions of transportation service on the Northern Border pipeline system. Northern Border Pipeline’s
revenues are derived from agreements for the receipt and delivery of natural gas at points along the Northern Border
pipeline system as specified in each shipper’s individual transportation contract. Northern Border Pipeline does not
own the natural gas that it transports, and therefore it does not assume the related natural gas commodity risk.

Northern Border Pipeline’s management is overseen by a four-member management committee. One represen-
tative is designated by TC PipeLines. Three representatives are designated by Northern Border Partners, with each of
its general partners selecting one representative. Voting power on the management committee is allocated among the
partners in accordance to their proportional interest in the general partner interests. As a result, the 70% voting power
of Northern Border Partners’ three representatives on the management committee is allocated as follows: 35% to the
representative designated by Northern Plains, 22.75% to the representative designated by Pan Border and 12.25% to
the  representative  designated  by  Northwest  Border. Northern  Plains  and  Pan  Border  are  subsidiaries  of Enron.
Therefore, Enron controls 57.75% of the voting power of the management committee and has the right to select two of

2001 ANNUAL REPORT

the members. On December 2, 2001, Enron filed a voluntary petition for Chapter 11 protection in bankruptcy court.
See  Item  7. “Management’s  Discussion  and  Analysis  of Financial  Condition  and  Results  of Operations  –  Results  of
Operations of Northern Border Pipeline Company – Impact of Enron’s Chapter 11 Filing on Northern Border Pipeline’s
Business.”

The Northern Border pipeline system is operated by Northern Plains pursuant to an operating agreement. As of
December 31, 2001, Northern Plains employed approximately 215 individuals located at Northern Plains’ headquar-
ters in Omaha, Nebraska, and at various locations along the pipeline route. Northern Plains’ employees are not repre-
sented by any labor union and are not covered by any collective bargaining agreements.

The Northern Border Pipeline System
Northern Border Pipeline owns a 1,249-mile interstate pipeline system that transports natural gas from the Montana-
Saskatchewan  border  near  Port  of Morgan, Montana  to  natural  gas  markets  in  the  midwestern  United  States.
Construction of the Northern Border pipeline system was initially completed in 1982. The Northern Border pipeline
system was expanded and/or extended in 1991, 1992, 1998 and 2001. The Northern Border pipeline system connects
directly and through multiple pipelines with various natural gas markets.

The Northern Border pipeline system consists of 822 miles of 42-inch diameter pipe designed to transport 2,374
million cubic feet per day (mmcfd) from the Canadian border to Ventura, Iowa; 30-inch diameter pipe and 36-inch
diameter pipe, each approximately 147 miles in length, designed to transport 1,484 mmcfd in total from Ventura, Iowa
to Harper, Iowa; 226 miles of 36-inch diameter pipe and 19 miles of 30-inch diameter pipe designed to transport 844
mmcfd from Harper, Iowa to Manhattan, Illinois (Chicago area); and 35 miles of 30-inch diameter pipe designed to
transport 545 mmcfd from Manhattan, Illinois to a terminus near North Hayden, Indiana. Along the pipeline there
are 16 compressor stations with total rated horsepower of 499,000 and measurement facilities to support the receipt
and delivery of natural gas at various points. Other facilities include four field offices and a microwave communica-
tion system with 51 tower sites.

On October 1, 2001, Northern Border Pipeline completed construction and began operation of its Project 2000
facilities. Project 2000 gives shippers access to industrial natural gas consumers in northern Indiana through an inter-
connect with Northern Indiana Public Service Company, a major midwest local distribution company, at the termi-
nus  near  North  Hayden, Indiana  and  provides  545  mmcfd  of transportation  capacity. Project  2000  also  expands
Northern Border Pipeline’s delivery capability into the Chicago area by approximately 30%. Capital expenditures for
Project 2000 are approximately $63 million. Project 2000 facilities include approximately 35 miles of 30-inch pipeline,
one 13,000 horsepower compressor station in Illinois, additional horsepower at two Iowa compressor stations and one
meter station.

The Northern Border pipeline system has pipeline access to natural gas reserves in the western Canadian sedi-
mentary basin in the provinces of Alberta, British Columbia and Saskatchewan in Canada, as well as the Williston
Basin  in  the  United  States. The  Northern  Border  pipeline  system  also  has  access  to  synthetic  gas  produced  at  the
Dakota Gasification plant in North Dakota. At its northern end, the Northern Border pipeline system’s natural gas
supplies are received through an interconnection with TransCanada’s majority-owned Foothills Pipe Lines (Sask.) Ltd.
system in Canada, which is connected to TransCanada’s Alberta System and the pipeline system owned by Transgas
Limited  in  Saskatchewan. The  Northern  Border  pipeline  system  also  connects  with  facilities  of Williston  Basin
Interstate Pipeline at Glen Ullin and Buford, North Dakota, facilities of Amerada Hess Corporation at Watford City,
North Dakota and facilities of Dakota Gasification Company at Hebron, North Dakota in the northern portion of the
Northern  Border  pipeline  system. For  the  year  ended  December  31, 2001, of the  natural  gas  transported  on  the
Northern Border pipeline system, approximately 90% was produced in Canada, approximately 5% was produced by
the Dakota Gasification plant and approximately 5% was produced in the Williston Basin.

Interconnects
The Northern Border pipeline system connects with multiple pipelines that provide its shippers with access to the var-
ious natural gas markets served by those pipelines. The Northern Border pipeline system interconnects with pipeline
facilities of:

•

Northern  Natural  Gas  Company, an  Enron  subsidiary  until  February  1, 2002, and  now  a  subsidiary  of
Dynegy, Inc., at Ventura, Iowa as well as multiple smaller interconnections in South Dakota, Minnesota and
Iowa;
Natural Gas Pipeline Company of America at Harper, Iowa; 

•
• MidAmerican Energy Company at Iowa City and Davenport, Iowa and Cordova, Illinois;

Border pipeline system.

The Ventura, Iowa interconnect with Northern Natural Gas Company functions as a large market center, where natural
gas transported on the Northern Border pipeline system is sold, traded and received for transport to significant con-
suming markets in the Midwest and to interconnecting pipeline facilities destined for other markets.

Shippers
The Northern Border pipeline system serves more than 50 firm transportation shippers with diverse operating and
financial profiles. Based upon shippers’ contractual obligations, as of December 31, 2001, 91% of the firm capacity is
contracted by producers and marketers. The remaining firm capacity is contracted to local distribution companies
(6%), interstate pipelines (2%) and end-users (1%). As of December 31, 2001, the termination dates of these contracts
ranged from March 31, 2002 to December 21, 2013, and the weighted average contract life, based upon annual con-
tractual obligations, was approximately five and one half years with just under 99% of capacity contracted through
mid-September 2003. Contracts for approximately 42% of the capacity will expire prior to November 2003. See Item 7.
“Management’s Discussion and Analysis of Financial Condition and Results of Operations – Results of Operations of
Northern Border Pipeline Company – Outlook.”

Northern Border Pipeline’s mix and number of shippers may change throughout the year as a result of its shippers
utilizing Northern Border Pipeline’s capacity release provisions that allow shippers to release all or part of their capacity to
other shippers either permanently for the full term of their contract or temporarily. Under the terms of Northern Border
Pipeline’s tariff, a temporary capacity release does not relieve the original contract shipper from its payment obligations if
the replacement shipper fails to pay for the capacity temporarily released to it. Shippers on the Northern Border pipeline
system temporarily released capacity during 2001 for varying periods of time. There were also permanent releases of
capacity to other shippers for the full term of the contracts.

As of December 31, 2001, Northern Border Pipeline’s largest shipper, Mirant Americas Energy Marketing, LP, is
obligated for approximately 33.7% of Northern Border Pipeline’s contracted firm capacity. Of this amount, 24.4% of
Northern Border Pipeline’s contracted firm capacity was obtained under temporary releases from Pan-Alberta Gas
(U.S.)  (Pan  Alberta)  for  a  term  through  October  31, 2002. Pan-Alberta’s  firm  contracts  expire  October 31, 2003.
Mirant Americas Energy Marketing, LP, manages the assets of Pan-Alberta Gas, Ltd., which include Pan-Alberta’s con-
tracts with Northern Border Pipeline.

Some of Northern Border Pipeline’s shippers are affiliated with Northern Border Pipeline’s general partners. Enron
North America Corp. (ENA), a subsidiary of Enron, which also has filed for bankruptcy protection, holds firm contracts
representing 3.5% of capacity, a portion of which (1.1%) has been temporarily released to a third party until October
31, 2002. The third party that holds the 1.1% of capacity has filed a complaint with the FERC requesting, in effect, that
its  contract  be  deemed  terminated  as  a  consequence  of ENA’s  filing  for  bankruptcy  protection. Northern  Border
Pipeline believes this shipper’s contract will remain in effect until October 31, 2002. ENA’s contractual obligations were
supported by guarantees from Enron, which are subject to Enron’s filing for bankruptcy protection. Transcontinental
Gas  Pipe  Line  Corporation, a  subsidiary  of Williams, holds  a  contract  representing  0.7%  of capacity. See  Item  7.

Northern Border Pipeline Company – Impact of Enron’s Chapter 11 Filing on Northern Border Pipeline’s Business.”

Demand For Transportation Capacity
Northern  Border  Pipeline’s  long-term  financial  condition  is  dependent  on  the  continued  availability  of economic
western Canadian natural gas supplies for import into the United States. Natural gas reserves may require significant
capital expenditures by others for exploration and development drilling and the installation of production, gathering,
storage, transportation and other facilities that permit natural gas to be produced and delivered to pipelines that inter-
connect with the interstate pipelines’ systems. Low prices for natural gas, regulatory limitations or the lack of available
capital for these projects could adversely affect the development of additional reserves and production, gathering, storage

2001 ANNUAL REPORT

and pipeline transmission of western Canadian natural gas supplies. Additional pipeline export capacity also could
accelerate depletion of these reserves. Furthermore, the availability of export capacity could also affect the demand or
value of the transport on the Northern Border pipeline system.

Northern  Border  Pipeline’s  business  also  depends  on  the  level  of demand  for  natural  gas  in  the  markets  the
pipeline system serves. The volumes of natural gas delivered to these markets from other sources affect the demand
for both the natural gas supplies and the use of the Northern Border pipeline system. Demand for natural gas to serve
other markets also influences the ability and willingness of shippers to use the Northern Border pipeline system to
meet demand in the markets that Northern Border Pipeline serves.

A variety of factors could affect the demand for natural gas in the markets that the Northern Border pipeline system

serves. These factors include:

•
•
•
•
•
•

economic conditions; 
fuel conservation measures; 
alternative energy requirements and prices; 
climactic conditions; 
government regulation; and 
technological advances in fuel economy and energy generation devices.

Interstate pipelines’ primary exposure to market risk occurs at the time existing transportation contracts expire and
are subject to renegotiation. A key determinant of the value that customers can realize from firm transportation on
the pipeline system is the basis differential or market price spread between two points on the pipeline. The difference
in natural gas prices between the points along the pipeline where natural gas enters and where natural gas is delivered
represents the gross margin that a customer can expect to achieve from holding transportation capacity at any point
in time. This margin and its variability become important factors in determining the level of demand charges cus-
tomers are willing to commit to when they renegotiate their transportation contracts. The basis differential between
markets can be affected by trends in production, available capacity, storage inventories, weather, and general market
demand in the respective areas.

TC PipeLines cannot predict whether these or other factors will have an adverse effect on demand for use of the

Northern Border pipeline system or how significant that adverse effect could be.

Interstate Pipeline Competition
Northern Border Pipeline competes with other pipeline companies that transport natural gas from the western Canadian
sedimentary basin or that transport natural gas to end-use markets in the midwest. Northern Border Pipeline’s compet-
itive position is affected by the availability of Canadian natural gas for export, the availability of other sources of natural
gas and demand for natural gas in the United States. Demand for transportation services on the Northern Border pipeline
system is affected by natural gas prices, the relationship between export capacity from and production in the western
Canadian sedimentary basin and natural gas shipped from producing areas in the United States. Shippers of natural gas
produced in the western Canadian sedimentary basin also have other options to transport Canadian natural gas to the
United States, including transportation on pipelines eastward in Canada or to markets on the West Coast.

The Alliance Pipeline, which was placed in service in December 2000, competes directly with Northern Border
Pipeline  in  the  transportation  of natural  gas  from  the  western  Canadian  sedimentary  basin  to  the  Chicago  area.
Williams  has  a  minority  interest  (14.6%)  in  Alliance  Pipeline. Because  it  transports  liquids-rich  natural  gas, the
Alliance Pipeline has no interconnections with other pipelines upstream of the liquids extraction facilities, which are
located near Chicago. This contrasts with the Northern Border pipeline system, which serves various markets through
interconnections with other pipelines along its route.

The competitive impact of the Alliance Pipeline has been mitigated by the continuing development of addition-
al capacity to ship natural gas from the Chicago area to other markets in the United States. Vector Pipeline L.P., which
interconnects with the Alliance Pipeline and transports natural gas eastward to a terminus in eastern Canada, com-
menced operations in December 2000. Guardian Pipeline proposes to be in service in November 2002 and to inter-
connect with Northern Border Pipeline. Guardian Pipeline is targeting markets in northern Illinois and Wisconsin and
could provide access to additional markets for Northern Border Pipeline’s shippers.

TransCanada and other unaffiliated companies own and operate pipeline systems that transport natural gas from

the same natural gas reserves in western Canada that supply Northern Border Pipeline’s shippers.

Natural gas is produced in the United States and is also transported by competing pipeline systems to the same

markets as those served by the Northern Border pipeline system.

FERC Regulation
Northern Border Pipeline is subject to extensive regulation by the FERC as a “natural gas company” under the Natural
Gas Act. Under the Natural Gas Act and the Natural Gas Policy Act, the FERC has jurisdiction with respect to virtual-
ly all aspects of Northern Border Pipeline’s business, including:

•
•
•
•
•
•
•
•

transportation of natural gas; 
rates and charges; 
construction of new facilities; 
extension or abandonment of service and facilities; 
accounts and records; 
depreciation and amortization policies; 
the acquisition and disposition of facilities; and 
the initiation and discontinuation of services.

Where required, Northern Border Pipeline holds certificates of public convenience and necessity issued by the FERC
covering the facilities, activities and services. Under Section 8 of the Natural Gas Act, the FERC has the power to pre-
scribe the accounting treatment for items for regulatory purposes. Northern Border Pipeline’s books and records may
be periodically audited under Section 8.

The FERC regulates the rates and charges for transportation in interstate commerce. Natural gas companies may
not charge rates exceeding rates judged just and reasonable by the FERC. Generally, rates are based on the cost of serv-
ice including recovery of and a return on the pipeline’s actual historical cost investment. In addition, the FERC pro-
hibits natural gas companies from unduly preferring or unreasonably discriminating against any person with respect
to pipeline rates or terms and conditions of service. Some types of rates may be discounted without further FERC
authorization and rates may be negotiated subject to FERC approval. The rates and terms and conditions for Northern
Border Pipeline’s service are found in its FERC approved Gas Tariff.

Under Northern Border Pipeline’s tariff, Northern Border Pipeline is allowed to charge for its services on the basis
of stated transportation rates established in Northern Border Pipeline’s 1999 rate case. Northern Border Pipeline also
may provide services under negotiated and discounted rates. Approximately 98% of the agreed upon cost of service or
revenue level is attributed to demand charges. Firm shippers that contract for the stated transportation rate are obli-
gated to pay a monthly demand charge, regardless of the amount of natural gas they actually transport, for the term
of their contracts. The remaining 2% of the agreed upon revenue level is attributed to commodity charges based on
the volumes of natural gas actually transported. Under the terms of settlement in Northern Border Pipeline’s 1999 rate
case, neither Northern Border Pipeline’s existing shippers nor Northern Border Pipeline can seek rate changes until
November  1, 2005, at  which  time  Northern  Border  Pipeline  must  file  a  new  rate  case. Prior  to  the  new  rate  case,
Northern Border Pipeline will not be permitted to increase rates if costs increase, nor will Northern Border Pipeline
be required to reduce rates based on cost savings. Northern Border Pipeline’s earnings and cash flow will depend on
future  costs, contracted  capacity, the  volumes  of natural  gas  transported  and  Northern  Border  Pipeline’s  ability  to
recontract capacity at acceptable rates.

Until new transportation rates are approved by FERC, Northern Border Pipeline continues to depreciate its trans-
mission plant at the FERC approved annual depreciation rate. Northern Border Pipeline’s annual depreciation rate on
transmission plant in service is 2.25%. In order to avoid a decline in transportation rates set in future rate cases as a
result of accumulated depreciation, Northern Border Pipeline must maintain or increase its rate base by acquiring or
constructing assets that replace or add to existing pipeline facilities or by adding new facilities.

In  Northern  Border  Pipeline’s  1995  rate  case, the  FERC  addressed  the  issue  of whether  the  federal  income  tax
allowance included in Northern Border Pipeline’s proposed cost of service was reasonable in light of recent FERC rulings.
In those rulings, the FERC held that an interstate pipeline is not entitled to a tax allowance for income attributable to
limited partnership interests held by individuals. The settlement of Northern Border Pipeline’s 1995 rate case provided
that until at least December 2005, Northern Border Pipeline could continue to calculate the allowance for income taxes
in the manner it had historically used. In addition, a settlement adjustment mechanism of $31 million was imple-
mented, which effectively reduces the return on rate base. These provisions of the 1995 rate case were maintained in
the settlement of Northern Border Pipeline’s 1999 rate case.

Northern Border Pipeline also provides interruptible transportation service. Interruptible transportation service is
transportation in circumstances when capacity is available after satisfying firm service requests. The maximum rate that
may  be  charged  to  interruptible  shippers  is  calculated  as  the  sum  of the  firm  transportation  maximum  reservation
charge and commodity rate. Under Northern Border Pipeline’s tariff, Northern Border Pipeline shares net interrupt-
ible transportation service revenue and any new services revenue on an equal basis with Northern Border Pipeline’s
firm shippers through October 31, 2003. In addition, Northern Border Pipeline is permitted to retain revenue from
interruptible transportation service to offset any decontracted firm capacity.

After October 31, 2003, all Northern Border Pipeline’s revenues from interruptible and other new transportation
service  will  no  longer  be  subject  to  sharing  and  thus, will  be  retained  by  Northern  Border  Pipeline. During  2001,
Northern Border Pipeline filed and received approval to implement several new services. Northern Border Pipeline
intends to continue to develop other new services to meet customer needs and seek the FERC’s authorization to imple-
ment such services. Revenues from these sources are expected to be minimal for the near term.

Northern Border Pipeline is subject to the requirements of FERC Order Nos. 497 and 566, which prohibit prefer-
ential treatment by interstate natural gas pipelines of their marketing affiliates and govern how information may be
provided to those marketing affiliates. In September 2001, the FERC issued a notice of Proposed Regulation proposing
new standards of conduct that would apply uniformly to natural gas pipelines and transmitting public utilities. FERC is
proposing one set of standards to govern relationships between regulated transmission providers and all energy affiliates.
Should a final rule be issued in this proceeding, Northern Border Pipeline may be subject  to standards that could
result in additional costs.

Environmental and Safety Matters
Northern Border Pipeline’s operations are subject to federal, state and local laws and regulations relating to safety and
the protection of the environment, which include the Resource Conservation and Recovery Act, the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, Clean Air Act, as amended, the Clean
Water Act, as amended, the Natural Gas Pipeline Safety Act of 1969, as amended, and the Pipeline Safety Act of 1992.
Although TC PipeLines believes that Northern Border Pipeline’s operations and facilities are in general compli-
ance in all material respects with applicable environmental and safety regulations, risks of substantial costs and liabil-
ities  are  inherent  in  pipeline  operations, and  TC  PipeLines  cannot  provide  any  assurances  that  Northern  Border
Pipeline will not incur such costs and liabilities. Moreover, it is possible that other developments, such as increasing-
ly strict environmental and safety laws, regulations and enforcement policies thereunder, and claims for damages to
property or persons resulting from Northern Border Pipeline’s operations, could result in substantial costs and liabil-
ities to Northern Border Pipeline. If Northern Border Pipeline is unable to recover such resulting costs, earnings and
cash distributions could be adversely affected.

Business of Tuscarora Gas Transmission Company
Tuscarora is a Nevada general partnership formed in 1993. Its general partners are TC Tuscarora Intermediate Limited
Partnership, a direct subsidiary of TC PipeLines, which holds a 49% general partner interest, Tuscarora Gas Pipeline
Co., a wholly owned subsidiary of Sierra Pacific Resources Company, which holds a 50% general partner interest and
TCPL Tuscarora Ltd., an indirect wholly owned subsidiary of TransCanada, which holds a 1% general partner interest.
The  management  of Tuscarora  is  overseen  by  a  management  committee  that  determines  the  policies  of, has
authority over the affairs of, and approves the actions of Tuscarora. The management committee participates in the
management of the construction, maintenance and operation of the Tuscarora pipeline system.

Under the Tuscarora partnership agreement, voting control is allocated among Tuscarora’s three general partners
in proportion to their general partner interests in Tuscarora. As a result, TC PipeLines has a 49% voting interest, Sierra
Pacific has a 50% voting interest, and TransCanada has a 1% voting interest on the Tuscarora management commit-
tee. Tuscarora Gas Operating Company, a subsidiary of Sierra Pacific, operates the Tuscarora pipeline system pursuant
to an operating agreement.

The Tuscarora Pipeline System
Tuscarora owns a 229-mile, 20-inch diameter, United States interstate pipeline system that originates at an intercon-
nection point with facilities of PG&E National Energy Group, Gas Transmission Northwest near Malin, Oregon and
runs southeast through northeastern California and northwestern Nevada. The Tuscarora pipeline system terminates
near Reno, Nevada at the Tracy Power Plant. Deliveries are also made directly to the local gas distribution system of
Sierra Pacific. Along its route, deliveries are made in Oregon, northern California and northwestern Nevada.

The  Tuscarora  pipeline  system  was  constructed  in  1995  and  was  placed  into  service  in  December  1995. The

Tuscarora pipeline system has the capacity to transport, on a firm basis, approximately 127 mmcfd of natural gas.

Tuscarora has firm transportation contracts for over 98% of its capacity, including contracts held by Sierra Pacific
Power Company, a subsidiary of Sierra Pacific, for 94% of the total available capacity, the majority of which expires
on November 30, 2015. As of December 31, 2001, the weighted average contract life on the Tuscarora pipeline system
was approximately fourteen years.

In  January  2001, Tuscarora  completed  construction  of the  Hungry  Valley  lateral, a  14-mile, 16-inch  pipeline
extension that serves as Tuscarora’s second connection into Reno, Nevada. Sierra Pacific Power holds firm capacity on
the  lateral  for  approximately  15  mmcfd  through  firm  transportation  contracts  that  expire  in  January  and  October
2016. The project was completed at a capital cost of approximately $8.0 million.

On January 30, 2002, the FERC issued a final certificate, approving the proposed expansion of Tuscarora’s pipeline
system. The Tuscarora expansion consists of three compressor stations and a 14-mile pipeline extension from the current
terminus of the Tuscarora pipeline system near Reno, Nevada to Wadsworth, Nevada. The expansion is expected to cost
$60 million and will increase Tuscarora’s capacity from 127 mmcfd to approximately 220 mmcfd. Approximately two-
thirds of the capital budget is expected to be spent in 2002. Commercial operations are targeted to begin in November
2002 with approximately 40% of the expansion volumes flowing. The full incremental 93 mmcfd of contracted volumes
are expected to be flowing by late 2003 when construction is expected to be completed. The expansion is supported by
long-term firm transportation contracts ranging from ten to fifteen years. Sierra Pacific Power has contracted for approx-
imately 11 mmcfd of the increased capacity. At the request of the Public Utilities Commission of Nevada, Tuscarora will
submit to a cost and revenue study to be conducted by the FERC within 3 years of the in service date of the expansion.
On March 15, 2002, Tuscarora issued Series C Senior Secured Notes in the amount of $10 million. These notes
bear interest at 6.89% and are due in 2012. The proceeds from these notes will be used to finance a portion of the con-
struction of Tuscarora’s expansion project.

Tuscarora’s competitive position is dependent on the continued availability of commercially attractive western
Canadian natural gas for import into the United States and on the level of demand for western Canadian natural gas
in the markets the Tuscarora pipeline system serves. Shippers of natural gas from the western Canadian sedimentary
basin  have  other  options  for  transporting  Canadian  natural  gas  to  the  United  States, including  transportation  on
pipelines eastward in Canada or to markets on the west coast of the United States and Canada. Similarly, natural gas
produced in the United States serves the same markets as Tuscarora in northern Nevada. Tuscarora is able to transport
both Canadian and United States natural gas providing Tuscarora with a well-diversified supply of natural gas to serve
its markets.

FERC Regulation
Tuscarora is subject to regulation by the FERC as a “natural gas company” under the Natural Gas Act, and is subject
to the FERC’s rules, regulations and accounting procedures.

Tuscarora generates revenues from individual transportation contracts with shippers that provide for the receipt and
delivery of natural gas at points along the Tuscarora pipeline system. Tuscarora’s transportation rates are based on its cost
of service as approved by the FERC. Tuscarora’s cost of service includes administrative and operating costs, depreciation
and amortization, taxes other than income taxes, an allowance for income taxes and a regulated return on capital employed.

Environmental and Safety Matters
Tuscarora’s operations are subject to federal, state and local laws and regulations relating to safety and protection of
the environment. TC PipeLines believes that Tuscarora’s operations and facilities comply in all material respects with
applicable United States environmental and safety regulations.

ITEM 2. PROPERTIES

TC PipeLines does not hold the right, title or interest in any properties.

Properties of Northern Border Pipeline Company
Northern  Border  Pipeline  holds  the  right, title  and  interest  in  its  pipeline  system. With  respect  to  real  property, the
Northern Border pipeline system falls into two basic categories: (a) parcels which are owned in fee, such as certain of the
compressor stations, meter stations, pipeline field office sites, and microwave tower sites; and (b) parcels where Northern
Border Pipeline’s interest derives from leases, easements, rights-of-way, permits or licenses from landowners or govern-
mental authorities permitting the use of such land for the construction and operation of the Northern Border pipeline

2001 ANNUAL REPORT

system. The right to construct and operate the Northern Border pipeline system across certain property was obtained by
Northern Border Pipeline through exercise of the power of eminent domain. Northern Border Pipeline continues to have
the  power  of eminent  domain  in  each  of the  states  in  which  Northern  Border  Pipeline  operates, although  Northern
Border Pipeline may not have the power of eminent domain with respect to Native American tribal lands.

Approximately 90 miles of the Northern Border pipeline system are located on fee, allotted and tribal lands within
the exterior boundaries of the Fort Peck Indian Reservation in Montana. Tribal lands are lands owned in trust by the
United States for the Fort Peck Tribes and allotted lands are lands owned in trust by the United States for an individual
Indian or Indians. Northern Border Pipeline does have the right of eminent domain with respect to allotted lands.

In 1980, Northern Border Pipeline entered into a pipeline right-of-way lease with the Fort Peck Tribal Executive Board,
for and on behalf of the Assiniboine and Sioux Tribes of the Fort Peck Indian Reservation. This pipeline right-of-way lease,
which was approved by the Department of the Interior in 1981, granted to Northern Border Pipeline the right and privilege
to construct and operate the Northern Border pipeline system on certain tribal lands. This pipeline right-of-way lease expires
in 2011.

In conjunction with obtaining a pipeline right-of-way lease across tribal lands located within the exterior bound-
aries of the Fort Peck Indian Reservation, Northern Border Pipeline also obtained a right-of-way across allotted lands
located within the reservation boundaries. Most of the allotted lands are subject to a perpetual easement either granted,
by the Bureau of Indian Affairs for and on behalf of individual Indian owners or obtained through condemnation.
Several tracts are subject to a right-of-way grant that has a term of 15 years, expiring in 2015.

Properties of Tuscarora Gas Transmission Company
Tuscarora holds the right, title and interest in its pipeline system. Tuscarora owns all of its material equipment and
personal property and leases office space in Reno, Nevada. With respect to real property, Tuscarora’s ownership falls
into two basic categories (a) parcels which it owns in fee, including meter stations; and (b) parcels where its interest
derives from leases, easements, grants, temporary use of permits or licenses from landowners or governmental author-
ities permitting the use of the land for the construction and operation of its pipeline system.

ITEM 3.

LEGAL PROCEEDINGS

TC PipeLines is not currently a party to any material legal proceedings.

On July 31, 2001, the Assiniboine and Sioux Tribes of the Fort Peck Indian Reservation filed a lawsuit in Tribal
Court against Northern Border Pipeline to collect more than $3 million in back taxes, together with interest and penal-
ties. The  lawsuit  relates  to  a  utilities  tax  on  certain  of Northern  Border  Pipeline’s  properties  within  the  Fort  Peck
Reservation. Based on recent decisions by the federal courts and other defenses, TC PipeLines believes that the Tribes
do not have authority to impose the tax and that the lawsuit will not have a material adverse impact on TC PipeLines.
Neither  Northern  Border  Pipeline  nor  Tuscarora  are  currently  party  to  any  other  legal  proceedings  that,
individually  or  in  the  aggregate, would  reasonably  be  expected  to  have  a  material  adverse  impact  on  TC
PipeLines’ results of operations or financial position.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

There were no matters submitted to a vote of security holders, through solicitation of proxies or otherwise, during the

As of March 11, 2002, there were approximately 93 record holders of common units and approximately 6,100 benefi-
cial owners of the common units, including common units held in street name.

The Partnership currently has 14,690,694 common units outstanding, of which 11,890,694 are held by the public
and 2,800,000 are held by an affiliate of the general partner. The Partnership also has 2,809,306 subordinated units
outstanding, all of which are held by the general partner, for which there is no established public trading market. The
common units and the subordinated units represent an aggregate 98% limited partner interest and the general partner
interest represents an aggregate 2% general partner interest in the Partnership.

In general, the general partner is entitled to 2% of all cash distributions and the holders of common units and sub-
ordinated units (collectively referred to as unitholders) are entitled to the remaining 98% of all cash distributions. The
Partnership will make quarterly cash distributions to its partners (including holders of subordinated units), comprising
all of its Available Cash. Available Cash is defined in the partnership agreement and generally means, with respect to any
quarter of the Partnership, all cash on hand at the end of such quarter less the amount of cash reserves that are necessary
or appropriate in the reasonable discretion of the general partner to (i) provide for the proper conduct of the business of
the Partnership (including reserves for future capital expenditures and for anticipated credit needs), (ii) comply with
applicable  laws  or  any  Partnership  debt  instrument  or  agreement, or  (iii)  provide  funds  for  cash  distributions  to
unitholders and the general partner in respect of any one or more of the next four quarters. Distributions of Available
Cash to the holder of subordinated units are subject to the prior rights of the holders of common units to receive the
minimum quarterly distribution for each quarter while the subordinated units are outstanding (subordination period),
and to receive any arrearages in the cash distribution of minimum quarterly distributions on the common units for prior
quarters during the subordination period. The partnership agreement defines the minimum quarterly distribution as
$0.45 for each full fiscal quarter.

The  general  partner  is  entitled  to  incentive  distributions  if the  amount  distributed  with  respect  to  any  quarter
exceeds the minimum quarterly distribution of $0.45 per common unit. Under the incentive distribution provisions,
the general partner is entitled to 15% of amounts distributed in excess of $0.45 per common unit, 25% of amounts dis-
tributed in excess of $0.5275 per common unit, and 50% of amounts distributed in excess of $0.69 per common unit
provided the balance has been first distributed to unitholders on a pro rata basis. The amounts that trigger incentive
distributions at various levels are subject to adjustment in certain events, as described in the partnership agreement.

On September 5, 2000, the Partnership announced an increase in the quarterly cash distribution from $0.45 per
unit to $0.475 per unit for the 2000 third quarter cash distribution, which was paid on November 14, 2000, resulting
in the first tier of incentive distributions being achieved. On July 19, 2001, the Partnership announced another increase
in the quarterly cash distribution from $0.475 per unit to $0.50 per unit for the 2001 second quarter cash distribution,
which was paid on August 14, 2001.

2001 ANNUAL REPORT

16

TC PPL 1675c AR01 10K  4/10/02  3:18 PM  Page 17

In 2001, the Partnership made cash distributions to the limited partners and the general partner that amounted to
$35.2 million. These payments represented the $0.475 per unit for the quarters ended December 31, 2000 and March
31, 2001 and $0.50 per unit for the quarters ended June 30, 2001 and September 30, 2001. On February 14, 2002, the
Partnership paid a cash distribution of $9.1 million to the limited partners and the general partner, representing a cash
distribution of $0.50 per unit for the quarter ended December 31, 2001.

Subordination Period
The subordination period extends until the first day of any quarter beginning after June 30, 2004 in respect of which:
(i) distributions of Available Cash from operating surplus on the common units and the subordinated units for each
of the three non-overlapping four-quarter periods immediately preceding that date equaled or exceeded the sum of
the minimum quarterly distribution on all of the outstanding common units and subordinated units during those
periods, (ii) the adjusted operating surplus generated during each of the three non-overlapping four-quarter periods
immediately preceding that date equaled or exceeded the sum of the minimum quarterly distribution on all of the
common units and the subordinated units that were outstanding on a fully diluted basis and the related distributions
on the general partner interest during those periods, and (iii) there are no arrearages in payment of the minimum
quarterly distribution on the common units.

Before the end of the subordination period and to the extent the tests for conversion described above are satisfied,
a portion of the subordinated units may convert into common units prior to June 30, 2004. Subordinated units will
convert into common units on a one-for-one basis on the first day after the record date established for the distribution
in  respect  of any  quarter  ending  on  or  after: (i)  June  30, 2002  with  respect  to  one-third  of the  subordinated  units
(936,435 subordinated units), and (ii) June 30, 2003 with respect to one-third of the subordinated units (936,435 sub-
ordinated units), in respect of which each of the financial tests described above have been satisfied; provided, however,
that the early conversion of the second one-third of subordinated units may not occur until at least one year following
the early conversion of the first one-third of subordinated units.

Upon expiration of the subordination period, all remaining subordinated units will convert into common units on a
one-for-one basis and will thereafter participate, pro rata with the other common units in distributions of Available Cash.

ITEM 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF

OPERATIONS

As a result of the Partnership’s ownership of investments in both Northern Border Pipeline and Tuscarora, the following
discusses first the results of operations and liquidity and capital resources of TC PipeLines, then those of each of Northern
Border Pipeline and Tuscarora in their entirety.

The following discussions of the financial condition and results of operations for the Partnership, Northern Border
Pipeline  and  Tuscarora  should  be  read  in  conjunction  with  the  financial  statements  and  notes  thereto  of the
Partnership and Northern Border Pipeline included elsewhere in this report (see Item 8. – “Financial Statements and
Supplementary Data”). For more detailed information regarding the basis of presentation for the following financial
information, see  the  notes  to  the  financial  statements  of the  Partnership  and  Northern  Border  Pipeline. As  of
December  31, 2001, TC  PipeLines’ interest  in  Northern  Border  Pipeline  represents  approximately  87%  of TC
PipeLines’ total  assets  and  has  provided  approximately  92%  of TC  PipeLines’ equity  income  for  the  year  ended
December 31, 2001. All amounts are stated in United States dollars.

Results of Operations of TC PipeLines, LP
Critical Accounting Policy
TC PipeLines accounts for its investments in both Northern Border Pipeline and Tuscarora using the equity method
of accounting  as  detailed  in  notes  three  and  four  to  the  financial  statements. The  equity  method  of accounting  is
appropriate where the investor is able to exercise significant influence over the operating and financial policies of an
investee. TC PipeLines is able to exercise significant influence over its investments in Northern Border Pipeline and
Tuscarora as evidenced by its representation on their respective management committees.

Since the 30% general partner interest in Northern Border Pipeline and the 49% general partner interest in Tuscarora
are currently the Partnership’s only material sources of income, the Partnership’s results of operations are influenced
by and reflect the same factors that influence the financial results of Northern Border Pipeline and Tuscarora.

Year Ended December 31, 2001 Compared with the Year Ended December 31, 2000
For the year ended December 31, 2001, TC PipeLines recorded equity income of $42.1 million from its investment in
Northern Border Pipeline, compared to $38.1 million for 2000, an increase of $4.0 million. Approximately $1.0 million
of this  increase  is  due  to  Project  2000, Northern  Border  Pipeline’s  35-mile  extension  and  expansion  into  northern
Indiana, which was completed in October 2001. An additional $1.9 million of the increase is due to lower operating
and maintenance costs as a result of Northern Border Pipeline’s efforts to reduce these costs offset by the reserve to
provide for November and December 2001 revenues due to Northern Border Pipeline under transportation agree-
ments with ENA, a subsidiary of Enron. ENA, which filed for Chapter 11 bankruptcy protection on December 2, 2001,
is in default of its payments to Northern Border Pipeline, starting with payments due for November 2001 (see “Results
of Operations  of Northern  Border  Pipeline  –  Impact  of Enron’s  Chapter  11  Filing  on  Northern  Border  Pipeline’s
Business”). Favorable interest rates decreased Northern Border Pipeline’s interest expense in 2001, further increasing
2001 equity income by $2.9 million. These increases to 2001 equity income were partially offset by lower other income
for Northern Border Pipeline in 2001, resulting in a $2.5 million decrease in 2001 equity income to TC PipeLines. In
2000, Northern Border Pipeline’s other income was higher due to non-recurring adjustments related to the approval of
its rate settlement agreement.

For the year ended December 31, 2001, TC PipeLines recorded equity income of $3.6 million from its investment in
Tuscarora, compared to $0.9 million for 2000, an increase of $2.7 million. This increase is attributed to the Partnership
acquiring its interest in Tuscarora in September 2000 and incremental revenues from Tuscarora’s 14-mile Hungry Valley
lateral, which was placed into service in January 2001.

General and administrative expenses were $1.3 million for each of the years ended December 31, 2001 and 2000.
Financial charges were $1.0 million for the year ended December 31, 2001 compared to $0.5 million in 2000. This
increase is attributed to the Partnership having a balance of $21.5 million outstanding on its Revolving Credit Facility
for the full year in 2001 compared to 2000 when the Partnership only had debt outstanding for four months of the
year partially offset by a decrease in interest rates in 2001. The Partnership drew on the Revolving Credit Facility in
September 2000 in order to fund a portion of the purchase price of a 49% general partner interest in Tuscarora.

Year Ended December 31, 2000 Compared with the Period May 28 to December 31, 1999
For the year ended December 31, 2000, TC PipeLines recorded equity income of $38.1 million from its investment in
Northern Border Pipeline, compared to $20.9 million for the period from May 28 to December 31, 1999. The $17.2
million increase reflects twelve months of activity in 2000 compared to approximately seven months of activity in 1999
(TC PipeLines acquired its 30% general partner interest in Northern Border Pipeline on May 28, 1999). In addition,
Northern Border Pipeline’s 2000 net income reflects its rate case settlement, resulting in incremental equity income to
TC PipeLines. Northern Border Pipeline also reduced reserves previously established for regulatory issues as the result
of the settlement of Northern Border Pipeline’s rate case, resulting in increased equity income to TC PipeLines.

For the year ended December 31, 2000, TC PipeLines recorded equity income of $0.9 million from its investment

in Tuscarora.

TC PipeLines incurred general and administrative expenses of $1.3 million for the year ended December 31, 2000
compared to $0.7 million for the period from May 28 to December 31, 1999. This increase reflects higher administra-
tive costs and a full year of operations in 2000.

The Partnership reported financial charges of $0.5 million for the year ended December 31, 2000, which includes
interest expense relating to the Partnership’s Revolving Credit Facility (see Item 7. “Management’s Discussion and Analysis
of Financial Condition and Results of Operations – Liquidity and Capital Resources of TC PipeLines, LP – General”). On
September 1, 2000, the Partnership borrowed $24.5 million under the Revolving Credit Facility to finance a portion of the
acquisition of a 49% general partner interest in Tuscarora. At December 31, 2000, the Partnership had $21.5 million out-
standing under the Revolving Credit Facility.

Liquidity and Capital Resources of TC PipeLines, LP
Cash Distribution Policy of TC PipeLines, LP
During the subordination period, which generally cannot end before June 30, 2004, the Partnership makes distribu-
tions of Available Cash in the following manner:

•

•

•

•

First, 98% to the common units, pro rata, and 2% to the general partner, until there is distributed for each
outstanding common unit an amount equal to the minimum quarterly distribution for that quarter;
Second, 98% to the common units, pro rata, and 2% to the general partner, until there is distributed for each
outstanding common unit an amount equal to any arrearages in payment of the minimum quarterly distri-
bution on the common units for that quarter and for any prior quarters during the subordination period;
Third, 98% to the subordinated units, pro rata, and 2% to the general partner, until there is distributed for
each outstanding subordinated unit an amount equal to the minimum quarterly distribution for that quar-
ter; and
Thereafter, in a manner whereby the general partner has rights (referred to as incentive distribution rights) to
receive increasing percentages of excess quarterly cash distributions over specified cash distribution thresholds.

General 
On January 18, 2002, the board of directors of the general partner declared the Partnership’s 2001 fourth quarter cash
distribution. The fourth quarter cash distribution, which was paid on February 14, 2002 to unitholders of record as of
January 31, 2002, totaled $9.1 million and was paid in the following manner: $7.3 million to common unitholders,
$1.4 million to the general partner as holder of the subordinated units, and $0.3 million to the general partner, as hold-
er of incentive distribution rights and in respect of its 2% general partner interest.

On August 22, 2000, the Partnership entered into an unsecured three-year credit facility (Revolving Credit Facility)
with a third party under which the Partnership may borrow up to an aggregate principal amount of $30.0 million. Loans
under the Revolving Credit Facility may bear interest, at the option of the Partnership, at a one-, two-, three-, or six-
month London Interbank Offered Rate (LIBOR) plus 0.875%, or at a floating rate based on the higher of the federal
funds effective rate plus 0.5% and the prime rate. The Revolving Credit Facility matures on August 31, 2003. Amounts
borrowed may be repaid in part or in full prior to that time without penalty. The Revolving Credit Facility may be used
to finance capital expenditures and for other general purposes. On September 1, 2000, the Partnership borrowed $24.5
million under the Revolving Credit Facility to fund a portion of the purchase price of the 49% general partner interest
in  Tuscarora. In  November  2000, the  Partnership  made  a  $3.0  million  principal  payment  on  the  Revolving  Credit
Facility. At December 31, 2001, the Partnership had $21.5 million outstanding under the Revolving Credit Facility. The
interest rate on the Revolving Credit Facility at December 31, 2001 and 2000 was 3.0% and 7.6%, respectively.

On  May  28, 2001, the  Partnership  renewed  its  $40.0  million  unsecured  two-year  revolving  credit  facility
(TransCanada  Credit  Facility)  with  TransCanada  PipeLine  USA  Ltd., an  affiliate  of the  general  partner. The

TC PIPELINES, LP

19

TC PPL 1675c AR01 10K  4/10/02  3:18 PM  Page 20

TransCanada Credit Facility bears interest at LIBOR plus 1.25%. The purpose of the TransCanada Credit Facility is to
provide borrowings to fund capital expenditures, to fund capital contributions to Northern Border Pipeline, Tuscarora
and any other entity in which the Partnership directly or indirectly acquires an interest, to fund working capital and
for other general business purposes, including temporary funding of cash distributions to partners, if necessary. At
December 31, 2001, the Partnership had no amount outstanding under the TransCanada Credit Facility.

Cash Flows from Operating Activities
Cash flows provided by operating activities increased to $43.0 million for the year ended December 31, 2001 from $40.4
million for 2000. In 2001, the Partnership received cash distributions of $42.9 million and $2.4 million from its invest-
ments in Northern Border Pipeline and Tuscarora, respectively, compared to $40.5 million and $1.5 million in 2000.

Cash flows provided by operating activities increased to $40.4 million for the year ended December 31, 2000 from
$11.8  million  for  the  period  May  28  to  December  31, 1999. For  the  period  May  28  to  December  31, 1999, the
Partnership received cash distributions of $12.1 million from Northern Border Pipeline.

Cash Flows from Investing Activities
Net cash used in investing activities decreased by $28.3 million for the year ended December 31, 2001 compared to
2000 due to the purchase of a 49% general partner interest in Tuscarora in 2000.

Cash Flows from Financing Activities
The Partnership paid cash distributions of $35.2 million in 2001 compared to $32.7 million in 2000. The increase in
cash distributions in 2001 is due to the Partnership increasing its cash distribution from $0.475 per unit to $0.50 per
unit beginning with the second quarter cash distribution in 2001.

For the period May 28 to December 31, 1999, the Partnership paid cash distributions of $11.0 million.
On September 1, 2000, the Partnership borrowed $24.5 million from the Revolving Credit Facility to fund a por-
tion of the purchase price of the 49% general partner interest in Tuscarora. At December 31, 2001, the Partnership had
$21.5 million outstanding under the Revolving Credit Facility.

Capital Requirements
To the extent TC PipeLines has any capital requirements with respect to its investments in Northern Border Pipeline and
Tuscarora or makes acquisitions in 2002, TC PipeLines expects to finance these requirements with debt and/or equity.

Results of Operations of Northern Border Pipeline Company
In the following discussion of the results of Northern Border Pipeline, all amounts represent 100% of the operations of
Northern Border Pipeline, in which the Partnership has held a 30% interest since May 28, 1999.

The discussion and analysis of Northern Border Pipeline’s financial condition and operations are based on Northern
Border  Pipeline’s  financial  statements, which  were  prepared  in  accordance  with  accounting  principles  generally
accepted in the United States of America. The following discussion and analysis should be read in conjunction with
Northern Border Pipeline’s financial statements included elsewhere in this report.

Critical Accounting Policies and Estimates
Certain amounts included in or affecting Northern Border Pipeline’s financial statements and related disclosures must
be estimated, requiring Northern Border Pipeline to make certain assumptions with respect to values or conditions
that cannot be known with certainty at the time the financial statements are prepared. The preparation of financial
statements in conformity with accounting principles generally accepted in the United States of America requires man-
agement to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure
of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those estimates. Any effects on Northern Border
Pipeline’s business, financial position or results of operations resulting from revisions to these estimates are recorded
in the period in which the facts that give rise to the revision become known.

Northern Border Pipeline’s significant accounting policies are summarized in Note 2 – Notes to Northern Border
Pipeline’s Financial Statements included elsewhere in this report. Certain of Northern Border Pipeline’s accounting
policies  are  of more  significance  in  their  financial  statement  preparation  process  than  others. Northern  Border
Pipeline’s accounting policies conform to Statement of Financial Accounting Standards (“SFAS”) No. 71, “Accounting
for the Effects of Certain Types of Regulation.” Accordingly, certain assets that result from the regulated ratemaking

2001 ANNUAL REPORT

20

TC PPL 1675c AR01 10K  4/10/02  3:18 PM  Page 21

process are recorded that would not be recorded under generally accepted accounting principles for nonregulated entities.
Northern Border Pipeline’s long-lived assets are stated at original cost. Northern Border Pipeline must use estimates
in determining the economic useful lives of those assets. For utility property, no retirement gain or loss is included in
income except in the case of extraordinary retirements or sales. The original cost of utility property retired is charged
to accumulated depreciation and amortization, net of salvage and cost of removal. Finally, Northern Border Pipeline’s
accounting  for  financial  instruments  follows  SFAS  No. 133, “Accounting  for  Derivative  Instruments  and  Hedging
Activities,” which Northern Border Pipeline adopted on January 1, 2001.

Year Ended December 31, 2001 Compared with the Year Ended December 31, 2000
Northern Border Pipeline’s net income to partners increased $13.4 million (11%) for the year ended December 31,
2001, as compared to the same period in 2000. Northern Border Pipeline benefited from reductions in interest rates,
which reduced Northern Border Pipeline’s interest expense for 2001 as compared to 2000. Northern Border Pipeline
was also able to control its operating costs resulting in reductions to operations and maintenance expenses.

Operating revenues, net increased $2.1 million for the year ended December 31, 2001, as compared to the same
period in 2000 primarily due to additional revenues associated with the completion of Project 2000 in October 2001.
See Item 1. “Business of Northern Border Pipeline Company – The Northern Border Pipeline System.”

Operations and maintenance expense decreased $7.9 million (19%) for the year ended December 31, 2001, as
compared to the same period in 2000, due primarily to a decrease in Northern Border Pipeline’s regulatory commis-
sion expense, decreased costs to operate two of Northern Border Pipeline’s electric-powered compressor units and
decreased employee payroll, benefit and administrative expenses for the Northern Border pipeline system. Operations
and  maintenance  expense  for  2001  includes  approximately  $1.3  million  of bad  debt  expense  related  to  ENA  (see
“Impact of Enron’s Chapter 11 Filing on Northern Border Pipeline’s Business”).

Taxes other than income decreased $2.3 million (8%) for the year ended December 31, 2001, as compared to the
same period in 2000, due primarily to a decrease in use taxes paid to the state of Minnesota. Northern Border Pipeline
had been paying Minnesota a use tax based on the fuel used at Northern Border Pipeline’s compressor stations locat-
ed in the state. A recent ruling by the Minnesota Supreme Court directed that the compressor fuel used was exempt
from this particular tax. Northern Border Pipeline filed for a refund of amounts previously paid, which was received
by Northern Border Pipeline in March 2002.

Interest expense, net decreased $9.8 million (15%) for the year ended December 31, 2001, as compared to the
same period in 2000, due primarily to a decrease in Northern Border Pipeline’s average interest rate between 2000 and
2001 as well as a decrease in average debt outstanding.

Other income (expense) decreased $8.5 million for the year ended December 31, 2001, as compared to the same
period in 2000. Other income (expense) for 2001 includes a net charge of approximately $1.5 million for an uncol-
lectible  receivable  from  a  telecommunications  company  that  had  purchased  excess  capacity  on  Northern  Border
Pipeline’s  communication  system. In  2000, Northern  Border  Pipeline  had  recorded  approximately  $1.7  million  of
income  from  the  sale  of excess  capacity  on  Northern  Border  Pipeline’s  communication  system. Other  income
(expense) for 2000 also included $5.6 million of income due to a reduction in reserves previously established for reg-
ulatory issues as the result of the settlement of Northern Border Pipeline’s rate case.

Year Ended December 31, 2000 Compared with the Year Ended December 31, 1999
Operating revenues, net for the year ended December 31, 2000 were $311.0 million as compared to $298.3 million for the
same period in 1999, an increase of $12.7 million (4%). Northern Border Pipeline’s net operating revenues for 2000 reflect
the significant terms of the rate case settlement discussed in Item 1.“Business of Northern Border Pipeline Company – FERC
Regulation.” Operating revenues for 1999 were determined under Northern Border Pipeline’s former cost of service tariff.
Operations and maintenance expense increased $2.8 million (7%) for the year ended December 31, 2000, from
the  same  period  in  1999, due  primarily  to  increased  employee  payroll  and  benefit  expenses  and  costs  to  operate
Northern Border Pipeline’s two electric-powered compressor units.

Depreciation and amortization expense increased $5.4 million (10%) for the year ended December 31, 2000, as
compared to the same period in 1999, due primarily to an increase in the depreciation rate applied to transmission
plant. As a result of the rate case settlement, Northern Border Pipeline used a depreciation rate for transmission plant
of 2.25% for 2000. Northern Border Pipeline had used a depreciation rate of 2.0% for 1999.

Taxes other than income decreased $2.3 million (8%) for the year ended December 31, 2000, as compared to the

same period in 1999, due primarily to adjustments to previous estimates of ad valorem taxes.

Interest expense, net increased $4.9 million (8%) for the year ended December 31, 2000, as compared to the same
period  in  1999, due  primarily  to  an  increase  in  average  interest  rates  between  1999  and  2000. The  impact  of the
increase in interest rates was partially offset by a decrease in average debt outstanding.

TC PIPELINES, LP

Other income increased $6.7 million (491%) for the year ended December 31, 2000, as compared to the same
period in 1999, due primarily to a reduction in reserves previously established for regulatory issues as the result of the
settlement of Northern Border Pipeline’s rate case.

Debt and Credit Facilities
In February 2002, Moodys’ Investor Services, Inc. (Moodys) placed Northern Border Pipeline on credit review for a
possible downgrade in credit rating. At this time, no action has been taken by Moodys. If Moodys was to issue the
downgrade, TC PipeLines expects Northern Border Pipeline’s credit rating to remain above investment grade.

Northern Border Pipeline had previously entered into a 1997 credit agreement (Pipeline Credit Agreement) with
certain financial institutions, which is comprised of a $100 million five-year revolving credit facility and a $272 mil-
lion term loan, both maturing in June 2002. At December 31, 2001, no amounts were outstanding under the five-year
revolving credit facility. Northern Border Pipeline anticipates refinancing the Pipeline Credit Agreement in the second
quarter of 2002. Northern Border Pipeline’s refinancing plans are to issue $225 million of senior notes and to enter
into a $175 million revolving credit facility.

At December 31, 2001, Northern Border Pipeline also had outstanding $143 million of senior notes issued in a $250
million private placement under a July 1992 note purchase agreement. The note purchase agreement provides for four
series of notes, Series A through D, maturing between August 2000 and August 2003. The Series A Notes with a principal
amount of $66 million and Series B Notes with a principal amount of $41 million were repaid in August 2000 and
August 2001, respectively. The Series C Notes with a principal amount of $78 million mature in August 2002. Northern
Border Pipeline anticipates borrowing on the refinanced Pipeline Credit Agreement to repay the Series C Notes.

In September 2001, Northern Border Pipeline completed a private offering of $250 million of 7.50% Senior Notes due
2021 (2001 Pipeline Senior Notes) and in August 1999, Northern Border Pipeline completed a private offering of $200 mil-
lion of 7.75% Senior Notes due 2009 (1999 Pipeline Senior Notes). Both the 2001 Pipeline Senior Notes and the 1999
Pipeline Senior Notes were subsequently exchanged in a registered offering for notes with substantially identical terms.
The  indentures  under  which  the  2001  Pipeline  Senior  Notes  and  1999  Pipeline  Senior  Notes  were  issued  do  not  limit 
the amount of unsecured debt Northern Border Pipeline may incur, but they do contain material financial covenants,
including restrictions on incurrence of secured indebtedness. The proceeds from the 2001 Pipeline Senior Notes and 1999
Pipeline Senior Notes were used to reduce indebtedness outstanding under the Pipeline Credit Agreement.

In  November  2001, Northern  Border  Pipeline  entered  into  forward  starting  interest  rate  swaps  with  notional
amounts totaling $150 million related to the planned issuance of senior notes discussed previously. The swaps were
entered into to hedge the fluctuations in Treasury rates and spreads between the execution date of the swaps and the
issuance date of the senior notes.

Short-term liquidity needs will be met by operating cash flows and through the Pipeline Credit Agreement, which
is being refinanced in 2002. Long-term capital needs may be met through Northern Border Pipeline’s ability to issue
long-term indebtedness.

Cash Flows From Operating Activities
Cash flows provided by operating activities increased $21.4 million to $197.3 million for the year ended December 31,
2001, as compared to the same period in 2000, primarily due to increased earnings and positive changes in working
capital. During 2001, Northern Border Pipeline realized net cash outflows of approximately $4.7 million related to
Northern Border Pipeline’s rate case refunds.

Cash flows provided by operating activities increased $4.5 million to $176.0 million for the year ended December
31, 2000, as compared to the same period in 1999, primarily due to increased earnings. During 2000, Northern Border
Pipeline realized net cash inflows of approximately $2.4 million related to Northern Border Pipeline’s rate case, which
included  approximately  $25.1  million  of amounts  collected  subject  to  refund  less  estimated  refunds  issued  in  late
December 2000 totaling approximately $22.7 million.

Cash Flows From Investing Activities
Capital expenditures of $54.7 million for the year ended December 31, 2001 included $49.0 million for Project 2000
(see Item 1. “Business of Northern Border Pipeline Company – The Northern Border Pipeline System”). For the same
period in 2000, capital expenditures were $15.5 million, which included $7.4 million for Project 2000. The remaining
capital expenditures for 2001 and 2000 are primarily related to renewals and replacements of existing facilities.

Total capital expenditures for 2002 are estimated to be $12 million, including $2.5 million for Project 2000. Northern
Border Pipeline currently anticipates funding its 2002 capital expenditures primarily by borrowing on debt facilities and
using operating cash flows.

Cash Flows From Financing Activities
Cash flows used in financing activities increased $12.0 million to $160.7 million for the year ended December 31, 2001,
as compared to the same period in 2000. Distributions to partners increased $8.1 million to $143.0 million for the year
ended December 31, 2001, as compared to the same period in 2000, primarily due to an increase in Northern Border
Pipeline’s net income. The net proceeds from the issuance of the 2001 Pipeline Senior Notes totaled approximately $247.2
million and were used for repayment of amounts borrowed under the Pipeline Credit Agreement. In August 2001 and
August 2000, Northern Border Pipeline repaid its Series B and A Notes of $41 million and $66 million, respectively, pri-
marily by borrowing under the Pipeline Credit Agreement. During the year ended December 31, 2001, Northern Border
Pipeline had net repayments under the Pipeline Credit Agreement of $197.0 million, which consisted of borrowings of
$136.0 million and repayments of $333.0 million. For the comparable period in 2000, Northern Border Pipeline had net
borrowings of $30.0 million, which consisted of borrowings of $75.0 million and repayments of $45.0 million. For the
year ended December 31, 2001, Northern Border Pipeline recognized a decrease in bank overdrafts of $22.4 million. At
December 31, 2000, Northern Border Pipeline reflected the bank overdraft primarily due to rate case refund checks out-
standing. In September 2001, Northern Border Pipeline paid approximately $4.1 million to terminate interest rate swap
agreements upon issuance of the 2001 Pipeline Senior Notes. The swaps were entered into to hedge the fluctuations in
Treasury rates and spreads between the execution date of the swaps and the issuance of the 2001 Pipeline Senior Notes.
Cash flows used in financing activities increased $58.8 million to $148.7 million for the year ended December 31,
2000, as compared to the same period in 1999. Distributions paid to the general partners increased $7.7 million to $134.9
million for the year ended December 31, 2000 as compared to the same period of 1999 primarily due to an increase in
Northern Border Pipeline’s net income. For the year ended December 31, 2000, borrowings under the Pipeline Credit
Agreement, which were primarily used to repay $66 million of Series A Notes, were $75 million as compared to borrow-
ings of $90 million for the same period in 1999, which were primarily used to finance a portion of the capital expendi-
tures  for  The  Chicago  Project, which  was  Northern  Border  Pipeline’s  expansion  and  extension  project  completed  in
December 1998. Financing activities for the year ended December 31, 1999 included $197.4 million from the issuance of
the 1999 Pipeline Senior Notes, net of associated debt discounts and issuance costs, and $12.9 million from the termina-
tion of interest rate forward agreements. Payments on the Pipeline Credit Agreement were $45 million for the year ended
December 31, 2000, as compared to $263 million for the same period in 1999. At December 31, 2000, Northern Border
Pipeline reflected bank overdrafts of approximately $22.4 million primarily due to refund checks outstanding.

Impact of Enron’s Chapter 11 Filing on Northern Border Pipeline’s Business
On December 2, 2001, Enron filed a voluntary petition for bankruptcy protection under Chapter 11 of the United States
Bankruptcy Code. A number of wholly owned Enron subsidiaries also filed for Chapter 11 bankruptcy protection on or
after December 2, 2001. Northern Border Pipeline has not filed for bankruptcy protection. Northern Plains, Pan Border
and Northwest Border are the general partners of Northern Border Partners, which holds a 70% general partner inter-
est in Northern Border Pipeline. Each of Northern Plains and Pan Border are wholly owned subsidiaries of Enron, and
Northwest Border is a wholly owned subsidiary of Williams. Northern Plains and Pan Border were not among the Enron
companies filing for Chapter 11 protection.

The businesses of Enron and its subsidiaries that have filed for bankruptcy protection are currently being admin-
istered under the direction and control of the bankruptcy court. An unsecured creditors committee has been appointed
in the Chapter 11 cases. The creditors committee is responsible for general oversight of the bankruptcy case, and has the
power, among other things, to: investigate the acts, conduct, assets, liabilities, and financial condition of the debtor, the
operation of the debtor's business and the desirability of the continuance of such business; participate in the formula-
tion of a plan of reorganization; and file acceptances or rejections to such a plan. Factors taken into account by Enron
in making its business decisions while in Chapter 11 may include decisions with respect to its investment in Northern
Plains, Pan Border and Northern Border Partners, which decisions may affect Northern Border Pipeline.

Current Effects  Enron’s bankruptcy filing has had an impact on Northern Border Pipeline. At the time of the filing of
the bankruptcy petition, Northern Border Pipeline had a number of contractual relationships with Enron and its sub-
sidiaries. Northern Plains provided and continues to provide operating and administrative services for Northern Border
Pipeline. Northern Plains has continued to meet its operational and administrative service obligations under the exist-
ing agreements, and Northern Border Pipeline believes Northern Plains will continue to do so.

ENA, a wholly owned subsidiary of Enron that is in bankruptcy, is a party to shipper contracts obligating ENA
to pay for 3.5% of Northern Border Pipeline’s capacity. Through October 31, 2002, ENA has temporarily released 1.1%
of this capacity to a third party. Although this third party has filed a complaint with the FERC requesting, in effect,
that its contracts be deemed terminated as a consequence of ENA’s filing for bankruptcy protection, Northern Border
Pipeline believes this shipper’s contract will remain in effect until October 31, 2002. ENA has not assumed or rejected
these contracts, but its ability to use the capacity has been suspended until it provides adequate assurance of credit
support. Northern  Border  Pipeline  estimates  that  it  has  aggregate  financial  exposure  over  the  next  12  months  of
approximately $9 million of revenues under its firm transportation contracts with ENA (TC PipeLines’ share equates
to approximately $2.7 million). Northern Border Pipeline believes that failure by ENA to perform its obligations under
the firm transportation contracts will not have a material adverse impact on its financial condition (see “Impact of
Enron’s Chapter 11 Filing on TC PipeLines’ Business”).

Northern Border Pipeline has retained outside counsel and TC PipeLines has been advised that Northern Border
Pipeline intends to assert and file claims against ENA’s bankruptcy estate related to these agreements. These claims will
likely be deemed to be unsecured claims against the Enron related Chapter 11 companies. Northern Border Pipeline is
uncertain regarding the ultimate amount of damages for breach of contract or other claims that it will be able to estab-
lish in the bankruptcy proceeding, and Northern Border Pipeline cannot predict the amounts that it will collect or the
timing of collection. Northern Border Pipeline believes, however, that any such delay in collecting or failure to collect
will  not  have  a  material  adverse  effect  on  its  financial  condition, and  any  amounts  collected  will  not  be  material  to
Northern Border Pipeline.

Enron’s filing for bankruptcy protection and the related developments have had other impacts on Northern Border
Pipeline’s business and management. On February 5, 2002, Arthur Andersen LLP resigned as Northern Border Pipeline’s
independent auditor, and Northern Border Pipeline subsequently retained KPMG LLP as its new independent auditor
for the fiscal year 2001 effective as of February 11, 2002. Enron has received several requests for information from dif-
ferent agencies and committees of the United States House of Representatives and Senate. Some of the information
requested from Enron may include information about Northern Border Pipeline. In addition, TC PipeLines is aware
that the Senate Committee on Governmental Affairs has issued a subpoena to Enron requesting documents disclosing
Enron’s communications with the Securities and Exchange Commission (SEC) and the FERC, as well as information on
compensation matters. As a result of Enron’s indirect ownership interest in Northern Border Pipeline, Northern Border
Pipeline has advised that it is willing to comply with the mandate of the subpoena in such a manner that may be deter-
mined by the Committee on Governmental Affairs of the Senate of the United States.

Possible Effects  While Northern Plains and Pan Border have not filed for Chapter 11 bankruptcy protection, they are whol-
ly owned subsidiaries of Enron, which is in bankruptcy. It is possible that in the course of Enron’s bankruptcy proceedings
Enron could attempt to sell its interest in Northern Plains and/or Pan Border, or take other action with respect to its invest-
ment in Northern Border Partners. Enron could also cause Northern Plains and Pan Border to file for bankruptcy protection.
Northern Border Pipeline has advised that it has had no current indication from Enron that it intends to sell all or a part of
its ownership interest in Northern Plains or Pan Border or cause either of these companies to file for bankruptcy protection.
Northern Border Pipeline is managed by a four-member management committee. One representative is designated by
TC PipeLines and three representatives are designated by Northern Border Partners, with each of its general partners select-
ing one representative. The vote among Northern Border Partners’ representatives on the Northern Border Pipeline man-
agement committee is in proportion to their general partner interests in Northern Border Partners. As a result, the 70% vot-
ing interest of Northern Border Partners’ three representatives is allocated 35%, 22.75% and 12.25% among Northern Plains,
Pan Border and Northwest Border, respectively. If Enron were to sell all of its ownership interest in each of Northern Plains
and Pan Border, the purchaser would have the right to appoint a majority of the Northern Border Pipeline management
committee and control the activities of Northern Border Pipeline, except for those activities requiring a unanimous vote, which
include changes to Northern Border Pipeline’s cash distribution policy, certain expansions and extensions of the Northern
Border pipeline system, some transfers of general partner interests and settlement of rate cases.

If Northern Plains and Pan Border were to file for bankruptcy protection, Northern Border Partners’ Partnership
Agreement provides that they would automatically be deemed to have withdrawn as general partners of Northern Border
Partners. It is possible that the enforceability of the automatic withdrawal provisions in this partnership agreement may be

2001 ANNUAL REPORT

24

TC PPL 1675c AR01 10K  4/10/02  3:19 PM  Page 25

challenged. The success and impact of a challenge are unknown. Upon the occurrence of such an event of withdrawal,
the remaining general partner of Northern Border Partners would have the right to purchase the withdrawing partners’
general partnership interests. Should the remaining general partner elect not to purchase these general partnership interests,
the limited partners of Northern Border Partners would have the right to elect new general partners. In either event, the
party acquiring the general partner interests currently held by Northern Plains and Pan Border would have the right to
appoint a majority of the Northern Border Pipeline management committee and control the activities of Northern Border
Pipeline, except for those activities requiring a unanimous vote.

Northern Plains also serves as operator of the Northern Border pipeline system. If Northern Plains were to file for
bankruptcy protection, it could potentially be removed as operator. Northern Border Pipeline’s 1997 credit agreements
provide that an event of default would occur if Northern Plains was replaced as operator without the consent of the lenders.
Other than the complaint against Norther Border Pipeline filed with the FERC by the shipper with temporarily
released  capacity, Northern  Border  Pipeline  has  advised  that  it  is  currently  not  aware  of any  claims  made  against
Northern Border Pipeline that arise out of the Enron bankruptcy cases.

Impact of Enron’s Chapter 11 Filing on TC PipeLines’ Business
Based on currently available information, TC PipeLines does not expect the impact of Enron’s bankruptcy protection
filing on Northern Border Pipeline to have a material impact on the business or financial condition of TC PipeLines.
TC PipeLines’ 30% share of Northern Border Pipeline’s aggregate financial exposure over the next 12 months under
Northern Border Pipeline’s firm transportation contracts with ENA equates to $2.7 million (see “Impact of Enron’s
Chapter 11 Filing on Northern Border Pipeline’s Business”).

TC  PipeLines  plans  to  continue  to  monitor  developments  at  Enron  and  to  continue  to  assess  any  impact  of
Enron’s  Chapter 11 proceedings on Northern Border Pipeline in light of Northern Border Pipeline’s existing agree-
ments and relationships with Enron and its subsidiaries, and to take all appropriate action to protect the interests of
TC PipeLines and its unitholders.

Outlook
Northern Border Pipeline will continue to focus on the safe, efficient, and reliable operations and the further develop-
ment of the Northern Border pipeline system. Northern Border Pipeline intends to maintain its position as a low cost
transporter  of Canadian  natural  gas  to  the  midwestern  U.S. and  provide  highly  valued  services  to  Northern  Border
Pipeline’s customers. Growth is expected to occur primarily in market areas Northern Border Pipeline serves through
incremental  projects  supported  by  long-term  contracts. Project  2000, Northern  Border  Pipeline’s  recently  completed
extension into Indiana, is a good example of the kinds of growth projects Northern Border Pipeline expects to pursue.
This project, completed on time and well under budget, connects Northern Border Pipeline directly to a large Chicago-
area gas distribution company, (Northern Indiana Public Service Company) and to industrial gas consumers in northern
Indiana. Northern Border Pipeline also intends to continue to expand the marketing of new services to meet its cus-
tomers’ needs. Depending on natural gas prices and natural gas development activities, selected opportunities to connect
new sources of supply to the Northern Border pipeline system may arise. Northern Border Pipeline is currently working
with  producers  and  marketers  to  develop  the  contractual  support  for  a  new  pipeline  project, the  Bison  Pipeline, to 
connect the coal bed methane reserves in the Powder River Basin to markets served by Northern Border Pipeline.

In 2002, Northern Border Pipeline will begin contract extension discussions with its customers for contracts that
will  expire  prior  to  November  1, 2003, which  represents  approximately  42%  of the  Northern  Border  pipeline  system
capacity. Similar to other industries, the value of capacity on interstate pipelines is driven by supply and demand condi-
tions. In particular, the relationship between natural gas prices in Canada and prices in the midwestern U. S. markets will
determine the underlying value of transportation. This relationship, and natural gas markets overall, has been volatile of
late, which is also an important factor in contracting for firm transportation capacity. Under Northern Border Pipeline’s
FERC tariff, Northern Border Pipeline may concurrently solicit bids for available capacity from other parties subject to
the existing customer’s rights to match the best offer. Northern Border Pipeline can begin this process during a period
that extends from 6 to 18 months before the termination date of the contract. The commencement of any bidding process
will be dependent upon the progress of negotiations and the market conditions affecting the value of transportation on
the pipeline. Based on current conditions, contracts for service on the Northern Border pipeline system may require dis-
counts from maximum transportation rates established in Northern Border Pipeline’s tariff and/or shorter duration than
its existing contract portfolio. Additionally, Northern Border Pipeline may enter into negotiated rate contracts involving
charges established on the basis of Canadian-midwestern U.S. natural gas price differentials or other factors.

Results of Operations of Tuscarora Gas Transmission Company
In the following discussion of the results of Tuscarora, all amounts represent 100% of the operations of Tuscarora, in which
the Partnership has held a 49% interest since September 1, 2000.

Year Ended December 31, 2001 Compared with the Year Ended December 31, 2000
Revenues generated by Tuscarora increased to $21.3 million for the year ended December 31, 2001 compared to $19.4
million in 2000 due to the Hungry Valley lateral which was placed into service in January 2001.

Tuscarora incurred costs and expenses of $2.6 million for the year ended December 31, 2001 compared to $2.4

million for the year ended December 31, 2000.

Tuscarora recorded depreciation of $4.6 million and $4.4 million for the years ended December 31, 2001, and

2000, respectively.

Tuscarora reported financial charges of $6.1 million and $6.0 million for the years ended December 31, 2001, and

2000, respectively.

Tuscarora reported other income of $0.3 million and $0.2 million for the years ended December 31, 2001 and

2000, respectively.

Year Ended December 31, 2000 Compared with the Year Ended December 31, 1999
Revenue generated by Tuscarora was $19.4 million and $19.3 million for the years ended December 31, 2000 and 1999,
respectively.

For the year ended December 31, 2000, Tuscarora incurred costs and expenses of $2.4 million compared to $2.9
million in 1999. The decrease in costs and expenses is primarily due to the capitalization of labor costs relating to the
construction of the Hungry Valley lateral and lower property taxes.

Tuscarora recorded depreciation of $4.4 million for each of the years ended December 31, 2000 and 1999.
Tuscarora recorded financial charges of $6.0 million and $6.2 million for the years ended December 31, 2000 and

1999, respectively.

Tuscarora recorded other income of $0.2 million for each of the years ended December 31, 2000 and 1999.

Liquidity and Capital Resources of Tuscarora Gas Transmission Company
General
In  September  2000, Tuscarora  adopted  a  cash  distribution  policy  that  became  effective  January  1, 2001. Under  the
terms of the cash distribution policy, Tuscarora will make quarterly cash distributions to its general partners in accor-
dance  with  their  respective  general  partner  interests. Cash  distributions  will  generally  be  computed  as  the  sum  of
Tuscarora’s net income before taxes and depreciation and amortization, less amounts required for debt repayments,
net of refinancings, maintenance capital expenditures, certain non-cash items, and any cash reserves deemed neces-
sary by the management committee. Cash distributions will be computed at the end of each calendar quarter and the
distribution will be made on or before the last day of the month following the quarter end.

In November 2001 and January 2002, Tuscarora entered into forward starting interest rate swaps with notional
amounts of $10 million and $8 million, respectively, related to the planned issuance of Series C Senior Secured Notes.
The swaps were settled on February 15, 2002 for net proceeds of approximately $0.2 million. The swaps were entered
into to hedge the fluctuations in treasury rates and spreads between the execution date of the swaps and the issuance
date of the Series C Senior Secured Notes.

On January 4, 2002, Tuscarora entered into a credit agreement with a third party for a $5 million, 364-day revolving

credit facility which bears interest at either the LIBOR rate plus 1% or the prime rate.

On March 15, 2002, Tuscarora issued Series C Senior Secured Notes in the amount of $10 million. These notes
bear interest at 6.89% and are due in 2012. The proceeds from these notes will be used to finance the construction of
Tuscarora’s expansion project.

Short-term liquidity needs will be met by operating cash flows and through the credit agreement discussed above.

Long-term capital needs may be met through the ability to issue long-term indebtedness.

Cash Flows from Operating Activities
Cash flows provided by operating activities increased to $13.4 million for the year ended December 31, 2001 compared
to $10.7 million in 2000. This increase is due to increased earnings and a decrease in working capital.

Cash flows provided by operating activities for the year ended December 31, 1999 were $10.7 million.

2001 ANNUAL REPORT

26

TC PPL 1675c AR01 10K  4/10/02  3:19 PM  Page 27

Cash Flows from Investing Activities
Net cash used in investing activities increased to $10.2 million for the year ended December 31, 2001 compared to $3.7
million for the same period in 2000. This increase is due to capital expenditures incurred in 2001 relating to the con-
struction of the Hungry Valley lateral and Tuscarora’s expansion project.

Net cash used in investing activities increased to $3.7 million for the year ended December 31, 2000 compared to
$0.7 million in 1999 due to capital expenditures incurred in 2000 relating to construction of the Hungry Valley lateral.

Cash Flows from Financing Activities
For the years ended December 31, 2001, 2000 and 1999 Tuscarora made debt repayments of $4.2 million, $3.6 million
and $2.8 million, respectively.

On December 19, 2000, Tuscarora issued Series B Senior Secured Notes in the amount of $8.0 million. These notes
bear interest at 7.99% and are due in 2010. The proceeds from these notes were used to finance the construction of
the Hungry Valley lateral.

Tuscarora paid cash distributions of $5.0 million, $5.3 million and $8.5 million to its general partners for the years
ended December 31, 2001, 2000 and 1999, respectively. The decrease in cash distributions in 2001 compared to 2000 is
due to the timing of implementation of the cash distribution policy. The decrease in cash distributions in 2000 compared
to 1999 is due to an increase in the amount of cash used to fund capital expenditures relating to the Hungry Valley lateral.

New Accounting Pronouncements
In the third quarter of 2001, the Financial Accounting Standards Board issued SFAS No. 141, “Business Combinations,”
SFAS No. 142, “Goodwill and Other Intangible Assets,” SFAS No. 143, “Accounting for Asset Retirement Obligations,”
and SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.”

SFAS No. 141 requires all business combinations initiated after June 30, 2001 to be accounted for using the pur-

chase method. The partnership did not enter into any business combinations subsequent to June 30, 2001.

SFAS No. 142 modifies the accounting and reporting of goodwill and intangible assets. It requires entities to dis-
continue the amortization of goodwill, reallocate goodwill among its reporting segments and perform initial impair-
ment tests by applying a fair-value-based analysis on the goodwill in each reporting segment. Subsequent to the ini-
tial adoption, goodwill must be tested for impairment annually or more frequently if circumstances indicate a possi-
ble impairment. For goodwill and intangible assets on the balance sheet at June 30, 2001, the provisions of SFAS No.
142 must be applied to fiscal years beginning after December 15, 2001. At December 31, 2001, the Partnership’s bal-
ance sheet does not include any goodwill.

SFAS No. 143 requires entities to record the fair value of a liability for an asset retirement obligation in the peri-
od in which it is incurred. When the liability is initially recorded, the entity capitalizes a cost by increasing the carry-
ing amount of the related long-lived asset. Over time, the liability is accreted to its present value and the capitalized
cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the
obligation for its recorded amount or incurs a gain or loss upon settlement. The standard is effective for fiscal years
beginning after June 15, 2002 with earlier application encouraged. The Partnership is in the process of evaluating the
application of this pronouncement on its investments in Northern Border Pipeline and Tuscarora.

SFAS No. 144 establishes one accounting model to be used for long-lived assets to be disposed of by sale, and
broadens the presentation of discontinued operations to include more disposal transactions. SFAS No. 144 supercedes
both SFAS No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
of ”, and the accounting and reporting provisions of APB Opinion No. 30. This standard is effective for fiscal years
beginning after December 15, 2001. The Partnership is in the process of evaluating the application of this pronounce-
ment on its investments in Northern Border Pipeline and Tuscarora.

Risk Factors and Cautionary Statement Regarding Forward Looking Information
Cautionary Statement Regarding Forward Looking Information
A number of statements made or incorporated by reference by TC PipeLines, in this Form 10-K filing made with the
SEC, are forward-looking and relate to, among other things, anticipated financial performance, business prospects,
strategies, market  forces  and  commitments. Much  of this  information  appears  in “Management’s  Discussion  and
Analysis  of Financial  Condition  and  Results  of Operations” found  herein. Forward-looking  information  typically 
contains  statements  with  words  such  as “anticipate,” “believe,” “estimate,” “expect,” “plan,” “target” or  similar  words
suggesting future outcomes. By its nature, such forward-looking information is subject to various risks and uncer-
tainties, which could cause TC PipeLines’ actual results and experience to differ materially from the anticipated results
or other expectations expressed in this Form 10-K. Readers are cautioned not to place undue reliance on this forward-
looking information, which is as of the date of this Form 10-K, and TC PipeLines undertakes no obligation to update
publicly or revise any forward-looking information, whether as a result of new information, future events or otherwise.

Risk Factors
TC PipeLines may not be able to generate sufficient cash from operations to pay the minimum quarterly distribution
on the common units every quarter
The actual amount of cash TC PipeLines has available to pay the minimum quarterly distribution will depend upon
numerous  factors  relating  to  each  of TC  PipeLines’, Northern  Border  Pipeline’s  and  Tuscarora’s  business, some  of
which are beyond the control of TC PipeLines or the general partner, including:

•

•
•
•

•
•
•
•
•
•

•

the tariff and transportation charges collected by Northern Border Pipeline and Tuscarora for transportation
services on their pipeline systems;
the amount of cash distributed to TC PipeLines by Northern Border Pipeline and Tuscarora;
the amount of cash set aside and the adjustment in reserves made by the general partner at its discretion;
the  amount  of cash  required  to  be  contributed  by  TC  PipeLines  to  either  Northern  Border  Pipeline  or
Tuscarora in the future;
required principal and interest payments on TC PipeLines debt;
the cost of acquisitions, including related debt service payments;
TC PipeLines’ issuance of debt and equity securities;
pipelines competing with Northern Border Pipeline and Tuscarora;
increases in Northern Border Pipeline’s and Tuscarora’s maintenance and operating costs;
payment defaults of shippers, including affiliates of Enron, on Northern Border’s pipeline system and 
payment defaults of shippers on Tuscarora’s pipeline system; and
expansion costs related to these systems.

Cash distributions are dependent primarily on TC PipeLines’ cash flow, financial reserves and working capital borrowings
Cash  distributions  are  not  dependent  solely  on  TC  PipeLines  profitability, which  is  affected  by  non-cash  items.
Therefore, TC PipeLines may make cash distributions during periods when losses are recorded and may not make cash
distributions during periods when profits are recorded.

TC PipeLines does not presently have sufficient stand-alone management resources to operate without services provided
by TransCanada
TransCanada provides all of TC PipeLines’ management resources. Further, TC PipeLines would not be able to evalu-
ate potential acquisitions and successfully complete acquisitions without TransCanada’s resources.

Northern Border Pipeline’s and Tuscarora’s indebtedness may limit their ability to borrow additional funds, make dis-
tributions to TC PipeLines or capitalize on business opportunities
Northern Border Pipeline is prohibited from making cash distributions during an event of default under its indebt-
edness. Provisions in Northern Border Pipeline’s indebtedness limit its ability to incur indebtedness and engage in 
specific transactions which could reduce its ability to capitalize on business opportunities that arise in the course of
its business. Tuscarora is prohibited from making cash distributions during an event of default under its indebtedness.
Under Tuscarora’s indebtedness, Tuscarora has granted a security interest in certain of its transportation contracts,
which are available to noteholders during an event of default. Any future refinancing of their existing indebtedness or
any new indebtedness could have similar or greater restrictions.

If TC PipeLines is unable to make acquisitions on economically and operationally acceptable terms, either from third
parties  or  TransCanada, TC  PipeLines’ future  financial  performance  will  be  limited  to  participation  in  Northern
Border Pipeline and Tuscarora
Future acquisitions may involve the expenditure of significant funds. Depending upon the nature, size and timing of
future acquisitions, TC PipeLines may be required to secure additional financing. Additional financing may not be
available to TC PipeLines on acceptable terms.

Majority control of the Northern Border Pipeline management committee by affiliates of Enron may limit TC PipeLines’
ability to influence Northern Border Pipeline
TC PipeLines owns a 30% general partner interest in Northern Border Pipeline. The remaining 70% general partner
interest in Northern Border Pipeline is owned by Northern Border Partners, a publicly traded limited partnership,
which is not affiliated with TC PipeLines. The general partners of Northern Border Partners are Northern Plains and
Pan Border, both subsidiaries of Enron, and Northwest Border, a subsidiary of The Williams Companies. Except as to

2001 ANNUAL REPORT

28

TC PPL 1675c AR01 10K  4/10/02  3:19 PM  Page 29

any matters requiring unanimity, such as significant expansions or extensions to the pipeline system, the acceptance
of rate cases and changes to, or suspensions of, the cash distribution policy, management committee members desig-
nated by subsidiaries of Enron have the power to approve a particular matter requiring a majority vote despite the fact
that TC PipeLines’ representative may vote against the project or other matter. Conversely, with respect to any matter
requiring a majority vote, management committee members designated by subsidiaries of Enron may disapprove a
particular matter despite the fact that TC PipeLines’ representative may vote in favor of that matter.

Northern Plains Natural Gas Company may not be able to continue to efficiently operate or may be forced to cease to
operate Northern Border Pipeline
Since Northern Plains is a wholly owned subsidiary of Enron it depends on Enron and some of its affiliates for some
of the administrative services Northern Plains provides to Northern Border Pipeline. Potential further developments
in the Enron situation may cause Northern Plains to be unable to provide a sufficient level of services or any services
as operator. Any interruption of services may have a significant impact on the operations of Northern Border Pipeline
and Northern Border Pipeline may not be able to transition to a new operator in a timely and efficient manner.

The IRS could treat TC PipeLines as a corporation, which would substantially reduce the cash available for distribu-
tion to unitholders
Current law may change so as to cause TC PipeLines to be taxable as a corporation for federal income tax purposes or
otherwise to be subject to entity-level taxation. The partnership agreement provides that, if a law is enacted or exist-
ing law is modified or interpreted in a manner that subjects TC PipeLines to taxation as a corporation or otherwise
subjects TC PipeLines to entity-level taxation for federal, state or local income tax purposes, then specified provisions
of the partnership agreement relating to distributions will be subject to change, including a decrease in distributions
to reflect the impact of that law on TC PipeLines.

Northern Border Pipeline and Tuscarora are extensively regulated by the FERC
If the FERC requires that Northern Border Pipeline’s or Tuscarora’s tariff be changed, Northern Border Pipeline’s or
Tuscarora’s cash flow may be adversely affected.

If Northern Border Pipeline or Tuscarora do not maintain or increase their respective rate bases by successfully com-
pleting FERC-approved projects, the amount of revenue attributable to the return on the rate base they collect from
their shippers will decrease over time
The Northern Border and Tuscarora pipeline systems are generally allowed to collect from their customers a return on
their assets or “rate base” as reflected in their financial records as well as recover that rate base through depreciation.
The amount they may collect from customers decreases as the rate base declines as a result of, among other things,
depreciation and amortization. In order to avoid a reduction in the level of cash available for distributions to its part-
ners based on its current FERC-approved tariff, each of these pipelines must maintain or increase its rate base through
projects that maintain or add to existing pipeline facilities. These projects will depend upon many factors including:

•
•
•
•
•

•
•

sufficient demand for natural gas;
an adequate supply of proved natural gas reserves;
available capacity on pipelines that connect with these pipelines;
the execution of natural gas transportation contracts;
the approval of any expansion or extension of the pipeline systems by their respective management commit-
tees, or in some cases, a ruling from an arbitrator;
obtaining financing for these projects; and
receipt and acceptance of necessary regulatory approvals.

Northern Border Pipeline’s and Tuscarora’s ability to complete these projects is also dependent on numerous business,
economic, regulatory, competitive and political uncertainties beyond its control, and neither Northern Border Pipeline
nor Tuscarora may be able to complete these projects.

If any  shipper  fails  to  perform  its  contractual  obligations, Northern  Border  Pipeline’s  or  Tuscarora’s  respective  cash
flows and financial condition could be adversely impacted
If any shipper fails to perform its contractual obligations, Northern Border Pipeline’s or Tuscarora’s cash flows and
financial condition could be adversely impacted. As a result, the cash available for distribution by TC PipeLines to
unitholders could be reduced.

As of December 31, 2001, the five largest shippers on the Northern Border pipeline system accounted for approx-
imately 48% of contracted capacity. ENA has 3.5% of the firm capacity on the Northern Border pipeline system. Since
November  2001, ENA  has  not  made  scheduled  payments  pursuant  to  these  firm  contracts  and  may  not  be  able  to
resume these payments. Northern Border Pipeline may not be able to re-contract any or a portion of the firm capacity
held by ENA on a short-term or long-term basis. Sierra Pacific Power is Tuscarora’s largest shipper, accounting for 94%
of Tuscarora’s contracted capacity.

The long-term financial conditions of Northern Border Pipeline and Tuscarora and as a result, of TC PipeLines, are
dependent on the continued availability of western Canadian natural gas for import into the United States
The development of additional natural gas reserves requires significant capital expenditures by others for exploration
and development drilling and the installation of production, gathering, storage, transportation and other facilities that
permit natural gas to be produced and delivered to pipelines that interconnect with Northern Border’s and Tuscarora’s
pipeline systems. Low prices for natural gas, regulatory limitations, or the lack of available capital for these projects
could adversely affect the development of additional reserves and production, gathering, storage and pipeline trans-
mission  and  import  and  export  of natural  gas  supplies. While  substantially  all  of Northern  Border  Pipeline’s  and
Tuscarora’s  capacity  is  contractually  committed  through  2003  and  2015, respectively, if the  availability  of western
Canadian natural gas were to decline over these periods, existing shippers may be unlikely to extend their contracts.
In  addition, Northern  Border  Pipeline  or  Tuscarora  may  be  unable  to  find  replacement  shippers  for  lost  capacity.
Northern Border Pipeline may not be able to replace its long-term contracts covering approximately 42% of its capacity
that expire in October of 2003 with long-term contracts under similarly attractive economic terms. Additional natural
gas reserves may not be developed in commercial quantities and in sufficient amounts to fill the capacities of each of
the Northern Border or Tuscarora pipeline systems.

Northern Border Pipeline’s and Tuscarora’s business depends in part on the level of demand for western Canadian nat-
ural gas in the markets the pipeline systems serve
The volumes of natural gas delivered to these markets from other sources affect the demand for both western
Canadian natural gas and use of these pipeline systems. Demand for western Canadian natural gas also influ-
ences the ability and willingness of shippers to use the Northern Border and Tuscarora pipeline systems to meet
the demand that these pipeline systems serve.

Natural gas is also produced in the United States and transported by competing unaffiliated pipeline systems to
the same destinations as natural gas transported by the Northern Border and Tuscarora pipeline systems. Because of
the highly competitive nature of the natural gas transmission business, Northern Border Pipeline and Tuscarora may
not be able to maintain existing customers or acquire new customers when the current shipper contracts expire. For
a discussion regarding contract profiles see Item 1. “Business of Northern Border Pipeline Company – Shippers” and
Item 1. “Business of Tuscarora Gas Transmission Company- The Tuscarora Pipeline System”

Northern Border Pipeline’s and Tuscarora’s operations are regulated by federal and state agencies responsible for envi-
ronmental protection and operational safety
TC PipeLines believes that these operations comply in all material respects with applicable environmental and safety
regulations. However, risks of substantial costs and liabilities are inherent in pipeline operations and each of Northern
Border Pipeline and Tuscarora may incur substantial costs and liabilities in the future as a result of stricter environ-
mental and safety laws, regulations and enforcement policies and claims for personal or property damages resulting from
Northern Border Pipeline’s or Tuscarora’s operations. If either Northern Border Pipeline or Tuscarora, as applicable, was
not able to recover these costs, cash distributions to TC PipeLines’ unitholders could be adversely affected.

Northern Border Pipeline’s and Tuscarora’s operations are subject to operational hazards and unforeseen interruptions,
including natural disasters, adverse weather, accidents or other events beyond its control. A casualty occurrence might result
in a loss of equipment or life, as well as injury and extensive property or environmental damage.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

TC PipeLines’ interest rate exposure results from its Revolving Credit Facility which is subject to variability in LIBOR
interest rates. If LIBOR interest rates change by one percent compared to the rates in effect as of December 31, 2001,
annual interest expense would change by approximately $0.2 million. This amount has been determined by considering
the impact of the hypothetical interest rates on variable rate borrowings outstanding as of December 31, 2001.

The Partnership’s market risk sensitivity is also influenced by and reflects the same factors that influence Northern

Border Pipeline.

TC PPL 1675c AR01 10K  4/10/02  3:19 PM  Page 31

Northern Border Pipeline’s interest rate exposure results from variable rate borrowings from commercial banks.
To mitigate potential fluctuations in interest rates, Northern Border Pipeline attempts to maintain a significant por-
tion of its debt portfolio in fixed rate debt. As of December 31, 2001, approximately 69% of Northern Border Pipeline’s
debt portfolio was in fixed rate debt.

If average interest rates change by one percent compared to rates in effect as of December 31, 2001, Northern Border
Pipeline’s annual interest expense would change by approximately $2.7 million. This amount has been determined by con-
sidering the impact of the hypothetical interest rates on variable rate borrowings outstanding as of December 31, 2001.

Section 16(a) Beneficial Ownership Reporting Compliance
Section 16(a) of the Exchange Act requires the Company’s directors and officers, and persons who own more than 10%
of the common units, to file initial reports of ownership and reports of changes in ownership (Forms 3, 4, and 5) of
the common units with the SEC and the Nasdaq Stock Market. Officers, directors and greater than 10% unitholders
are required by SEC regulation to furnish the Partnership with copies of all such forms that they file.

Except as set forth below, based solely on the Partnership’s review of the copies of such reports received by the
Partnership and on written representations by certain reporting persons that no reports on Form 5 were required, the
Partnership believes that during the fiscal year ended December 31, 2001 all Section 16(a) filing requirements appli-
cable to its officers, directors and holders of 10% or more of its common units were complied with in a timely man-
ner. The Form 3 required to be filed by Mr. Stephen Clark within 10 days of his appointment as an officer of the gen-
eral partner on January 25, 2001 and the Form 4 confirming his resignation as of October 1, 2001 were filed late on
March 5, 2001 and March 15, 2002, respectively, due to a clerical error.

ITEM 13.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

An affiliate of the general partner owns 2,800,000 common units and the general partner owns 2,809,306 subordinat-
ed units, representing an aggregate 31.4% limited partner interest in the Partnership. In addition, the general partner
owns  an  aggregate  2%  general  partner  interest  in  the  Partnership  through  which  it  manages  and  operates  the
Partnership.

The general partner is accountable to TC PipeLines and the unitholders as a fiduciary. Neither the Delaware Act
nor case law defines with particularity the fiduciary duties owed by general partners to limited partners of a limited
partnership. The Delaware Act does provide that Delaware limited partnerships may, in their partnership agreements,
restrict or expand the fiduciary duties owed by a general partner to limited partners and the partnership.

In order to induce the general partner to manage the business of TC PipeLines, the partnership agreement contains
various provisions restricting the fiduciary duties that might otherwise be owed by the general partner. The following
is a summary of the material restrictions of the fiduciary duties owed by the general partner to the limited partners.

•

•

•

•

The partnership agreement permits the general partner to make a number of decisions in its “sole discretion.”
This entitles the general partner to consider only the interests and factors that it desires and it shall have no
duty or obligation to give any consideration to any interest of, or factors affecting, TC PipeLines, its affiliates
or  any  limited  partner. Other  provisions  of the  partnership  agreement  provide  that  the  general  partner’s
actions must be made in its reasonable discretion.

The partnership agreement generally provides that affiliated transactions and resolutions of conflicts of inter-
est not involving a required vote of unitholders must be “fair and reasonable” to TC PipeLines. In determin-
ing whether a transaction or resolution is “fair and reasonable” the general partner may consider interests of
all parties involved, including its own. Unless the general partner has acted in bad faith, the action taken by
the general partner shall not constitute a breach of its fiduciary duty.

The partnership agreement specifically provides that it shall not be a breach of the general partner’s fiduci-
ary duty if its affiliates engage in business interests and activities in competition with, or in preference or to
the exclusion of, TC PipeLines. Also, the general partner and its affiliates have no obligation to present busi-
ness opportunities to TC PipeLines.

The partnership agreement provides that the general partner and its officers and directors will not be liable
for monetary damages to TC PipeLines, the limited partners or assignees for errors of judgment or for any
acts or omissions if the general partner and those other persons acted in good faith.

TC PipeLines is required to indemnify the general partner and its officers, directors, employees, affiliates, partners,
members, agents and trustees (collectively referred to hereafter as the General Partner and others), to the fullest extent
permitted by law, against liabilities, costs and expenses incurred by the General Partner and others. This indemnifica-
tion is required if the General Partner and others acted in good faith and in a manner they reasonably believed to be
in, or  (in  the  case  of a  person  other  than  the  general  partner)  not  opposed  to, the  best  interests  of TC  PipeLines.
Indemnification is required for criminal proceedings if the General Partner and others had no reasonable cause to
believe their conduct was unlawful.

The Partnership does not have any employees. The management and operating functions are provided by the gen-
eral partner. The general partner does not receive a management fee or other compensation in connection with its
management  of the  Partnership. The  Partnership  reimburses  the  general  partner  for  all  costs  of services  provided,
including the costs of employee, officer and director compensation and benefits, and all other expenses necessary or
appropriate to the conduct of the business of, and allocable to the Partnership. The partnership agreement provides
that the general partner will, in its sole discretion, determine the expenses that are allocable to the Partnership in any
reasonable manner determined by it. Total costs reimbursed to the general partner by the Partnership were approxi-
mately $0.5 million for the year ended December 31, 2001. Such costs include, (i) personnel costs (such as salaries and
employee benefits), (ii) overhead costs (such as office space and equipment) and (iii) out-of-pocket expenses related
to the provision of services to the Partnership.

On  May  28, 2001, the  Partnership  renewed  its  $40.0  million  unsecured  two-year  revolving  credit  facility
(TransCanada  Credit  Facility)  with  TransCanada  PipeLine  USA  Ltd., an  affiliate  of the  general  partner. The
TransCanada Credit Facility bears interest at LIBOR plus 1.25%. The purpose of the TransCanada Credit Facility is to
provide borrowings to fund capital expenditures, to fund capital contributions to Northern Border Pipeline, Tuscarora
and any other entity in which the Partnership directly or indirectly acquires an interest, to fund working capital, and
for other general business purposes, including temporary funding of cash distributions to partners, if necessary. At
December 31, 2001, the Partnership had no amount outstanding under the TransCanada Credit Facility.

On September 1, 2000, TC PipeLines, based on the approval of a committee comprised of its independent direc-
tors, acquired a 49% general partner interest in Tuscarora. The Partnership acquired this asset from TCPL Tuscarora
Ltd., an indirect subsidiary of TransCanada, for a purchase price of $28.0 million. The Partnership borrowed $24.5
million  from  the  Revolving  Credit  Facility  (see  Item  7. –  “Management’s  Discussion  and  Analysis  of Financial
Condition and Results of Operations - Liquidity and Capital Resources of TC PipeLines, LP – General”) to fund a por-
tion of the purchase price. The remainder of the purchase price was funded with cash on hand.

Mr. Helman, a director of the general partner of the Partnership, is a partner of the law firm of Mayer, Brown, Rowe
& Maw, which provides legal services on U.S. related matters to TransCanada, the parent of the general partner. Mayer,
Brown, Rowe & Maw also provides limited legal services to the general partner on behalf of the Partnership solely
relating to matters arising from Enron’s voluntary petition for bankruptcy protection.

INDEPENDENT AUDITORS’ REPORT

To the Board of Directors of TC PipeLines GP, Inc., General Partner of TC PipeLines, LP:

We  have  audited  the  accompanying  balance  sheets  of TC  PipeLines, LP  (a  Delaware  limited  partnership)  as  of
December 31, 2001 and 2000 and the related statements of income, comprehensive income, cash flows and changes in
partners’ equity for the years ended December 31, 2001 and 2000 and the period from the commencement of opera-
tions on May 28, 1999 to December 31, 1999. These financial statements are the responsibility of the General Partner.
Our responsibility is to express an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  auditing  standards  generally  accepted  in  the  United  States  of
America. Those standards require that we plan and perform an audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence sup-
porting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting prin-
ciples used and significant estimates made by management, as well as evaluating the overall financial statement pres-
entation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial posi-
tion of TC PipeLines, LP as of December 31, 2001 and 2000 and the results of its operations and its cash flows for the
years ended December 31, 2001 and 2000 and the period from the commencement of operations on May 28, 1999 to
December 31, 1999 in conformity with accounting principles generally accepted in the United States of America.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 ORGANIZATION
TC  PipeLines, LP, and  its  subsidiary  limited  partnerships, TC  PipeLines  Intermediate  Limited  Partnership, and  TC
Tuscarora Intermediate Limited Partnership, all Delaware limited partnerships, are collectively referred to herein as TC
PipeLines or the Partnership. TC PipeLines was formed by TransCanada PipeLines Limited (TransCanada) to acquire,
own and participate in the management of United States based pipeline assets.

TC  PipeLines  owns  a  30%  general  partner  interest  in  Northern  Border  Pipeline  Company  (Northern  Border
Pipeline), a Texas general partnership. Northern Border Pipeline owns a 1,249-mile United States interstate pipeline sys-
tem that transports natural gas from the Montana-Saskatchewan border to markets in the midwestern United States.

TC  PipeLines  also  owns  a  49%  general  partner  interest  in  Tuscarora  Gas  Transmission  Company  (Tuscarora), a
Nevada general partnership. Tuscarora owns a 229-mile United States interstate pipeline system that transports natural gas
from Oregon, where it interconnects with facilities of PG&E National Energy Group, Gas Transmission Northwest, to
northern Nevada.

TC PipeLines is managed by its general partner, TC PipeLines GP, Inc. (General Partner), a wholly-owned sub-
sidiary of TransCanada. The General Partner provides certain administrative services for the Partnership and is reim-
bursed for its costs and expenses. In addition to its 2% general partner interest, the General Partner owns 2,809,306
subordinated units, representing an effective 15.7% limited partner interest in the Partnership at December 31, 2001.
TransCanada indirectly holds 2,800,000 common units representing an effective 15.7% limited partner interest in the
Partnership at December 31, 2001.

NOTE 2 SIGNIFICANT ACCOUNTING POLICIES
(a) Basis of Presentation
The  accompanying  financial  statements  and  related  notes  present  the  financial  position  of the  Partnership  as  of
December 31, 2001 and 2000 and the results of its operations, comprehensive income, cash flows and changes in part-
ners’ equity for the years ended December 31, 2001 and 2000 and for the period from May 28, 1999 (commencement of
operations) to December 31, 1999. The Partnership uses the equity method of accounting for its investments in Northern
Border  Pipeline  and  Tuscarora, over  which  it  is  able  to  exercise  significant  influence. Other  comprehensive  income
recorded by TC PipeLines arises through its equity investments in Northern Border Pipeline and Tuscarora and relates to
cash flow hedges transacted by Northern Border Pipeline and Tuscarora. Amounts are stated in United States dollars.

(b) Use of Estimates
The preparation of financial statements in conformity with generally accepted accounting principles requires man-
agement to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure
of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Although management believes these estimates are reasonable, actual results
could differ from these estimates.

(c) Cash and Cash Equivalents
Cash equivalents consist of highly liquid investments with original maturities of three months or less. The carrying
amount of cash and cash equivalents approximates fair value because of the short maturity of these investments.

(d) Partners’ Equity
Costs incurred in connection with the issuance of units are deducted from the proceeds received.

(e) Income Taxes
No provision for income taxes related to the operations of the Partnership is included in the accompanying financial
statements because, as a partnership, it is not subject to Federal or state income tax. The tax effect of the Partnership’s
activities accrues to its partners.

NOTE 3 INVESTMENT IN NORTHERN BORDER PIPELINE COMPANY
The Partnership owns a 30% general partner interest in Northern Border Pipeline. The remaining 70% partnership
interest in Northern Border Pipeline is held by Northern Border Partners, L.P., a publicly traded limited partnership
that  is  not  affiliated  with  TC  PipeLines. The  general  partners  of Northern  Border  Partners, L.P. are  controlled  by
Enron Corp. (Enron) and The Williams Companies, Inc. (Williams). As a result, TC PipeLines has one member and

TC PIPELINES, LP

F–6

TC PPL 1675c AR01 10K  4/10/02  3:19 PM  Page F–7

controls 30% of the voting power of the Northern Border Pipeline management committee, Enron has two members
and controls 57.75% of the voting power, and Williams has one member and controls 12.25% of the voting power of
the Northern Border Pipeline management committee. The Northern Border pipeline system is operated by Northern
Plains  Natural  Gas  Company, a  wholly  owned  subsidiary  of Enron. Northern  Border  Pipeline  is  regulated  by  the
Federal Energy Regulatory Commission (FERC).

The Northern Border pipeline system serves more than 50 firm transportation shippers with diverse operations
and financial profiles. As of December 31, 2001, Enron North America (ENA) an affiliate of Enron holds firm con-
tracts representing approximately 3.5% of Northern Border Pipeline’s contracted capacity. Northern Border Pipeline
recorded a bad debt expense of approximately $1.3 million representing ENA’s unpaid November and December 2001
transportation. Through October 31, 2002, ENA has temporarily released 1.1% of this capacity to a third party. This
third party has filed a complaint with the FERC requesting, in effect, that its contract be deemed terminated as a con-
sequence  of ENA’s  filing  for  bankruptcy  protection. Northern  Border  Pipeline  believes  this  shipper’s  contract  will
remain in effect until October 31, 2002. Northern Border Pipeline estimates that it has aggregate financial exposure
over the next 12 months of approximately $9 million of revenues under its firm transportation contracts with ENA
(TC PipeLines’ share equates to approximately $2.7 million). Northern Border Pipeline believes that failure by ENA to
perform its obligations under the firm transportation contracts will not have a material adverse impact on its finan-
cial condition and results of operations.

TC  PipeLines’ equity  income  amounted  to  $42.1  million, $38.1  million  and  $20.9  million  for  the  years  ended
December 31, 2001 and 2000 and the period May 28 to December 31, 1999, respectively, representing 30% of the net
income  of Northern  Border  Pipeline  for  the  same  periods. Undistributed  earnings  of Northern  Border  Pipeline
amounted to $5.7 million and $6.4 million for the years ended December 31, 2001 and 2000, respectively.

The following sets out summarized financial information for Northern Border Pipeline as at December 31, 2001
and 2000 and for the years ended December 31, 2001, 2000 and 1999. TC PipeLines has held its general partner inter-
est since May 28, 1999.

remaining  50%  and  1%  interests  in  Tuscarora  are  indirectly  held  by  Sierra  Pacific  Resources  Company  and
TransCanada, respectively. The Partnership acquired its interest in Tuscarora from TCPL Tuscarora Ltd., an indirect
subsidiary of TransCanada, for a purchase price of $28.0 million. The Partnership borrowed $24.5 million from the

Revolving Credit Facility (see Note 5) to fund a portion of the purchase price. The remainder of the purchase price
was funded with cash on hand. Tuscarora is regulated by the FERC.

TC PipeLines’ equity income from Tuscarora for the year ended December 31, 2001 and the period September 1,
to December 31, 2000 amounted to $3.6 million and $0.9 million, respectively, representing 49% of the net income of
Tuscarora for the same periods. Undistributed earnings of Tuscarora amounted to $0.6 million and nil for the years
ended December 31, 2001 and 2000, respectively.

The following sets out summarized financial information for Tuscarora as at and for the years ended December

NOTE 5 CREDIT FACILITIES AND LONG-TERM DEBT
On August 22, 2000, the Partnership entered into an unsecured three-year credit facility (Revolving Credit Facility) with Bank
One, NA, as agent under which the Partnership may borrow up to an aggregate principal amount of $30.0 million. Loans
under the Revolving Credit Facility bear interest at a floating rate. The Revolving Credit Facility matures on August 31, 2003.
Amounts borrowed may be repaid in part or in full prior to that time without penalty. The Revolving Credit Facility may be
used to finance capital expenditures and for other general purposes. On September 1, 2000, the Partnership borrowed $24.5
million under the Revolving Credit Facility to fund a portion of the purchase price of the 49% general partner interest in
Tuscarora. At December 31, 2001 and 2000, the Partnership had borrowings of $21.5 million outstanding under the Revolving
Credit Facility. The fair value of the Revolving Credit Facility approximates its carrying value because the interest rate is a
floating rate. The interest rate on the Revolving Credit Facility averaged 5.19% for the year (2000 – 7.57%; 1999- nil) and was
3.02% at the end of the year (2000 – 7.62%; 1999- nil). Interest paid during the years ended December 31, 2001 and 2000 and
the period May 28 to December 31, 1999 was $1.2 million, $0.5 million and nil, respectively.

On May 28, 2001, the Partnership renewed its $40.0 million unsecured two-year revolving credit facility (TransCanada
Credit Facility), with TransCanada PipeLine USA Ltd., an affiliate of the General Partner. The TransCanada Credit Facility
bears interest at London Interbank Offered Rate plus 1.25%. The purpose of the TransCanada Credit Facility is to provide
borrowings to fund capital expenditures, to fund capital contributions to Northern Border Pipeline, Tuscarora and any
other entity in which the Partnership directly or indirectly acquires an interest, to fund working capital and for other gen-
eral business purposes, including temporary funding of cash distributions to partners, if necessary. At December 31, 2001
and 2000, the Partnership had no amount outstanding under the TransCanada Credit Facility.

NOTE 6 PARTNERS’ CAPITAL AND CASH DISTRIBUTIONS
Partners’ capital consists of 14,690,694 common units representing an 82.3% limited partner interest (an affiliate of
the  General  Partner  owns  2,800,000  of such  common  units), 2,809,306  subordinated  units  owned  by  the  General
Partner representing a 15.7% limited partner interest and a 2% general partner interest. In the aggregate, the General
Partner’s and its affiliate’s interests represent an effective 33.4% ownership of the Partnership’s equity.

The Partnership will make cash distributions to its partners with respect to each calendar quarter within 45 days after
the  end  of each  quarter. Distributions  are  based  on  available  cash  which  includes  all  cash  and  cash  equivalents  of the
Partnership and working capital borrowings less reserves established by the General Partner. The Unitholders are entitled to
receive the minimum quarterly distribution (MQD) of $0.45 per unit if and to the extent there is sufficient available cash.
Distributions to holders of the subordinated units are subject, while subordinated units remain outstanding (Subordination
Period), to the prior rights of holders of the common units to receive the MQD. The Subordination Period generally cannot
end before June 30, 2004. Upon expiration of the Subordination Period, all subordinated units will be converted on a one-
for-one basis into common units and will participate pro rata with all other common units in future distributions. Under
certain circumstances, up to 66.7% of the subordinated units may convert into common units prior to the expiration of the
Subordination  Period. Common  units  will  not  accrue  arrearages  with  respect  to  distributions  for  any  quarter  after  the
Subordination Period and subordinated units will not accrue any arrearages with respect to distributions for any quarter.

As an incentive, the General Partner’s percentage interest in quarterly distributions is increased after certain spec-
ified target levels are met. The incremental incentive distributions payable to the General Partner are 15%, 25%, and
50% of all quarterly distributions of Available Cash that exceed target levels of $0.45, $0.5275, $0.69, respectively, per
unit. For the years ended December 31, 2001 and 2000 and the period May 28 to December 31, 1999, the Partnership
distributed $1.975 , $1.85 and $1.068, respectively, per unit. The distributions for the year ended December 31, 2001
and 2000 and the period May 28 to December 31, 1999 included incentive distributions to the General Partner in the
amount of $0.6 million, $0.2 million and nil, respectively.

Partnership income is allocated to the General Partner and the limited partners in accordance with their respec-
tive partnership percentages, after giving effect to any priority income allocations for incentive distributions that are
allocated 100% to the General Partner.

NOTE 7 NET INCOME PER UNIT
Net income per unit is computed by dividing net income, after deduction of the General Partner’s allocation, by the
weighted average number of common and subordinated units outstanding. The General Partner’s allocation is equal
to an amount based upon the  General Partner’s 2% interest, adjusted to reflect an amount equal to incentive distri-
butions. Net income per unit was determined as follows:

NOTE 10 ACCOUNTING PRONOUNCEMENTS
In the third quarter of 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards
(SFAS) No. 141,“Business Combinations,” SFAS No. 142,“Goodwill and Other Intangible Assets,” SFAS No. 143,“Accounting
for Asset Retirement Obligations,” and SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.”

SFAS No. 141 requires all business combinations initiated after June 30, 2001 to be accounted for using the pur-

chase method. The Partnership did not enter into any business combinations subsequent to June 30, 2001.

SFAS No. 142 modifies the accounting and reporting of goodwill and intangible assets. It requires entities to discon-
tinue the amortization of goodwill, reallocate goodwill among its reporting segments and perform initial impairment tests
by applying a fair-value-based analysis on the goodwill in each reporting segment. Subsequent to the initial adoption, good-
will shall be tested for impairment annually or more frequently if circumstances indicate a possible impairment. For good-
will and intangible assets on the balance sheet at June 30, 2001, the provisions of SFAS No. 142 must be applied to fiscal years
beginning after December 15, 2001. At December 31, 2001, the Partnership’s balance sheet does not include any goodwill.
SFAS No. 143 requires entities to record the fair value of a liability for an asset retirement obligation in the period
in which it is incurred. When the liability is initially recorded, the entity capitalizes a cost by increasing the carrying
amount of the related long-lived asset. Over time, the liability is accreted to its present value and the capitalized cost is
depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation
for its recorded amount or incurs a gain or loss upon settlement. The standard is effective for fiscal years beginning after
June 15, 2002, with earlier application encouraged. The Partnership is in the process of evaluating the impact of the
application of this pronouncement on its investments in Northern Border Pipeline and Tuscarora.

SFAS No. 144 establishes one accounting model to be used for long-lived assets to be disposed of by sale, and
broadens the presentation of discontinued operations to include more disposal transactions. SFAS No. 144 supercedes
both SFAS No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
of ”, and the accounting and reporting provisions of APB Opinion No. 30. This standard is effective for fiscal years
beginning after December 15, 2001. The Partnership is in the process of evaluating the application of this pronounce-
ment on its investments in Northern Border Pipeline and Tuscarora.

NOTE 11 SUBSEQUENT EVENTS
On January 18, 2002, the Board of Directors of the General Partner declared a cash distribution of $0.50 per unit relat-
ed to the three months ended December 31, 2001. The $9.1 million distribution is payable on February 14, 2002 in
the following manner: $7.3 million to the holders of common units as of the close of business on January 31, 2001,
$1.4 million to the General Partner as holder of the subordinated units, and $0.3 million to the General Partner as
holder of incentive distribution rights and in respect of its 2% general partner interest.

NOTES TO FINANCIAL STATEMENTS

ORGANIZATION AND MANAGEMENT

Northern  Border  Pipeline  Company  (Northern  Border  Pipeline)  is  a  Texas
general  partnership  formed  in  1978.    The  ownership  percentages  of  the
partners in Northern Border Pipeline (Partners) at December 31, 2001 and
2000, are as follows:

Partner

Northern Border Intermediate Limited Partnership
TC PipeLines Intermediate Limited Partnership

Ownership
Percentage

70
30

Net income and distributions are allocated to the Partners based on own-
ership percentage.  Effective May 28, 1999, TransCanada Border PipeLine
Ltd. and TransCan Northern Ltd. transferred their combined 30% ownership
interest in Northern Border Pipeline to TC PipeLines Intermediate Limited
Partnership (TC PipeLines) in connection with an initial public offering
of  limited  partner  interests  in  TC  PipeLines,  LP.    In  accordance  with
the partnership agreement, net income and distributions were prorated at
the effective date of the ownership transfer.

Northern  Border  Pipeline  owns  a  1,249-mile  natural  gas  transmission
pipeline  system  extending  from  the  United  States-Canadian  border  near
Port of Morgan, Montana, to a terminus near North Hayden, Indiana.

Northern  Border  Pipeline  is  managed  by  a  Management  Committee  that
includes  three  representatives  from  Northern  Border  Intermediate
Limited  Partnership  (Partnership)  and  one  representative  from  TC
PipeLines.  The Partnership’s representatives selected by its general
partners,  Northern  Plains  Natural  Gas  Company  (Northern  Plains),  a
wholly-owned subsidiary of Enron Corp. (Enron), Pan Border Gas Company
(Pan  Border),  a  wholly-owned  subsidiary  of  Northern  Plains,  and
Northwest  Border  Pipeline  Company,  a  wholly-owned  subsidiary  of  The
Williams  Companies,  Inc.  (Williams),  have  35%,  22.75%  and  12.25%,
respectively, of the voting interest on the Management Committee.  The
representative  designated  by  TC  PipeLines  votes  the  remaining  30%
interest.    The  day-to-day  management  of  Northern  Border  Pipeline’s
affairs  is  the  responsibility  of  Northern  Plains  (the  Operator),  as
defined by the operating agreement between Northern Border Pipeline and
Northern Plains.  Northern Border Pipeline is charged for the salaries,
benefits  and  expenses  of  the  Operator.    For  the  years  ended  December
31, 2001, 2000, and 1999, Northern Border Pipeline’s charges from the
Operator totaled approximately $29.5 million, $31.7 million and $29.7
million, respectively.  Additionally, Northern Border Pipeline has uti-
lized Enron affiliates for management on pipeline expansion and exten-
sion  projects.    See  Note  10  for  a  discussion  of  Northern  Border
Pipeline’s relationships with Enron and developments involving Enron.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(A)

Use of Estimates

The preparation of financial statements in conformity with account-
ing  principles  generally  accepted  in  the  United  States  of  America
requires  management  to  make  estimates  and  assumptions  that  affect
the reported amounts of assets and liabilities and disclosure of con-
tingent assets and liabilities at the date of the financial state-
ments and the reported amounts of revenues and expenses during the
reporting period.  Actual results could differ from those estimates.

(B)

Government Regulation

Northern  Border  Pipeline  is  subject  to  regulation  by  the  Federal
Energy  Regulatory  Commission  (FERC).    Northern  Border  Pipeline’s
accounting  policies  conform  to  Statement  of  Financial  Accounting
Standards  (SFAS)  No.  71,  “Accounting  for  the  Effects  of  Certain
Types of Regulation.” Accordingly, certain assets that result from
the  regulated  ratemaking  process  are  recorded  that  would  not  be
recorded  under  accounting  principles  generally  accepted  in  the
United  States  of  America  for  nonregulated  entities.    At
December 31, 2001 and 2000, Northern Border Pipeline has reflect-
ed regulatory assets of approximately $11.5 million and $12.4 mil-
lion, respectively, in other assets on the balance sheet.  Northern
Border Pipeline is recovering the regulatory assets from its ship-
pers over varying time periods, which range from five to 44 years.

(C)

Revenue Recognition

Northern Border Pipeline transports gas for shippers under a tar-
iff regulated by the FERC.  The tariff specifies the calculation of
amounts to be paid by shippers and the general terms and conditions
of transportation service on the pipeline system.  Northern Border
Pipeline’s revenues are derived from agreements for the receipt and
delivery of gas at points along the pipeline system as specified in
each shipper’s individual transportation contract.  Northern Border
Pipeline does not own the gas that it transports, and therefore it
does not assume the related natural gas commodity risk.

(D)

Income Taxes

Income  taxes  are  the  responsibility  of  the  Partners  and  are  not
reflected  in  these  financial  statements.    However,  the  Northern
Border  Pipeline  FERC  tariff  establishes  the  method  of  accounting
for  and  calculating  income  taxes  and  requires  Northern  Border
Pipeline to reflect in its rates the income taxes, which would have
been  paid  or  accrued  if  Northern  Border  Pipeline  were  organized
during the period as a corporation.  As a result, for purposes of
determining transportation rates in calculating the return allowed
by the FERC, Partners’ capital and rate base are reduced by the

Income Taxes (continued)

amount  equivalent  to  the  net  accumulated  deferred  income  taxes.
Such  amounts  were  approximately  $336  million  and  $326  million  at
December 31, 2001 and 2000, respectively, and are primarily relat-
ed to accelerated depreciation and other plant-related differences.

(E)

Cash and Cash Equivalents

Cash  equivalents  consist  of  highly  liquid  investments  with  origi-
nal maturities of three months or less.  The carrying amount of cash
and  cash  equivalents  approximates  fair  value  because  of  the  short
maturity of these investments.

(F)

Property, Plant and Equipment and Related Depreciation and
Amortization

Property,  plant  and  equipment  is  stated  at  original  cost.    During
periods  of  construction,  Northern  Border  Pipeline  is  permitted  to
capitalize  an  allowance  for  funds  used  during  construction,  which
represents the estimated costs of funds used for construction pur-
poses.  The original cost of property retired is charged to accu-
mulated  depreciation  and  amortization,  net  of  salvage  and  cost  of
removal.  No retirement gain or loss is included in income except
in the case of extraordinary retirements or sales.

Maintenance  and  repairs  are  charged  to  operations  in  the  period
incurred.    The  provision  for  depreciation  and  amortization  of  the
transmission line is an integral part of Northern Border Pipeline’s
FERC tariff.  The effective depreciation rates applied to Northern
Border  Pipeline’s  transmission  plant  in  2001,  2000  and  1999  were
2.25%,  2.25%  and  2.0%,  respectively.    Composite  rates  are  applied
to all other functional groups of property having similar economic
characteristics.

Risk Management

Financial  instruments  are  used  by  Northern  Border  Pipeline  in  the
management  of  its  interest  rate  exposure.    A  control  environment
has been established which includes policies and procedures for risk
assessment and the approval, reporting and monitoring of financial
instrument activities.  Northern Border Pipeline does not use these
instruments for trading purposes.  See Note 6 for a discussion of
Northern  Border  Pipeline’s  accounting  for  derivative  instruments
and hedging activities.

RATES AND REGULATORY ISSUES

Rate Case

Northern Border Pipeline’s revenue is derived from agreements with var-
ious shippers for the transportation of natural gas.  It transports gas
under a FERC regulated tariff.  Northern Border Pipeline had used a cost
of  service  form  of  tariff  since  its  inception  but  agreed  to  convert  to
a stated rate form of tariff as part of the settlement of its 1999 rate
case discussed below. 

Under the cost of service tariff, Northern Border Pipeline was provided
an opportunity to recover all of the operations and maintenance costs of
the pipeline, taxes other than income taxes, interest, depreciation and
amortization,  an  allowance  for  income  taxes  and  a  regulated  return  on
equity.  Northern Border Pipeline was generally allowed to collect from
its shippers a return on regulated rate base as well as recover that rate
base through depreciation and amortization.  Billings for the firm trans-
portation  agreements  were  based  on  contracted  volumes  to  determine  the
allocable  share  of  the  cost  of  service  and  were  not  dependent  upon  the
percentage of available capacity actually used.  

Northern  Border  Pipeline  filed  a  rate  proceeding  with  the  FERC  in  May
1999  for,  among  other  things,  a  redetermination  of  its  allowed  equity
rate  of  return.    The  total  annual  cost  of  service  increase  due  to
Northern  Border  Pipeline’s  proposed  changes  was  approximately  $30  mil-
lion.    In  June  1999,  the  FERC  issued  an  order  in  which  the  proposed
changes were suspended until December 1, 1999, after which the proposed
changes were implemented with subsequent billings subject to refund.

In  September  2000,  Northern  Border  Pipeline  filed  a  stipulation  and
agreement  with  the  FERC  that  documented  the  proposed  settlement  of  its
1999  rate  case.    The  settlement  was  approved  by  the  FERC  in  December
2000.  Under the approved settlement, effective December 1, 1999, ship-
pers began paying stated transportation rates based on a straight fixed
variable  rate  design.    Under  the  straight  fixed  variable  rate  design,
approximately  98%  of  the  agreed  upon  revenue  level  is  attributed  to
demand  charges,  based  upon  contracted  firm  capacity,  and  the  remaining
2% is attributed to commodity charges, based on the volumes of gas actu-
ally  transported  on  the  system.  Under  the  settlement,  both  Northern
Border Pipeline and its existing shippers will not be able to seek rate
changes  until  November  1,  2005,  at  which  time  Northern  Border  Pipeline
must file a new rate case.

RATES AND REGULATORY ISSUES (continued)

Rate Case (continued)

After the FERC approved the rate case settlement and prior to the end of
2000,  Northern  Border  Pipeline  made  estimated  refund  payments  to  its
shippers totaling approximately $22.7 million, primarily related to the
period from December 1999 to November 2000.  During the first quarter of
2001,  Northern  Border  Pipeline  paid  the  remaining  refund  obligation  to
its shippers totaling approximately $6.8 million, which related to peri-
ods through January 2001.

Certificate application

On  March 16,  2000,  the  FERC  issued  an  order  granting  Northern  Border
Pipeline’s  application  for  a  certificate  to  construct  and  operate  an
expansion  and  extension  of  its  pipeline  system  into  Indiana  (Project
2000).    The  facilities  for  Project  2000  were  placed  into  service  on
October 1, 2001.  The capital expenditures for the project are expected
to be approximately $63 million, of which $60.5 million had been incurred
through December 31, 2001.  

4.

TRANSPORTATION SERVICE AGREEMENTS

Operating revenues are collected pursuant to the FERC tariff through firm
transportation  service  agreements.    The  firm  service  agreements  extend
for  various  terms  with  termination  dates  that  range  from  March  2002  to
December 2013.  Northern Border Pipeline also has interruptible service
agreements with numerous other shippers.  Under the approved settlement
of  the  rate  case  discussed  in  Note  3,  Northern  Border  Pipeline  will
reduce  the  billings  for  the  firm  service  agreements  by  one  half  of  the
revenues  received  from  the  interruptible  service  agreements  through
October 31, 2003.  Northern Border Pipeline is permitted to retain rev-
enue from interruptible transportation service to offset any decontract-
ed  firm  service.    After  October  31,  2003,  all  revenues  from  interrupt-
ible transportation service will be retained by Northern Border Pipeline.

Under the capacity release provisions of Northern Border Pipeline’s FERC
tariff,  shippers  are  allowed  to  release  all  or  part  of  their  capacity
either permanently for the full term of the contract or temporarily.  A
temporary capacity release does not relieve the original contract ship-
per from its payment obligations if the replacement shipper fails to pay
for the capacity temporarily released to it.

At December 31, 2001, Northern Border Pipeline’s largest shipper, Mirant
Americas  Energy  Marketing,  LP  (Mirant)  is  obligated  for  approximately
33.7% of the contracted firm capacity, which consists of the following:
24.4%  from  temporary  releases  of  firm  capacity  from  Pan-Alberta  Gas
(U.S.)  Inc.  (PAGUS)  and  9.3%  from  permanent  releases  of  firm  capacity
from  TransCanada  Energy  Marketing  USA,  Inc.  (TransCanada  Energy),  an
affiliate of TC PipeLines.  The PAGUS firm service agreements expire in

TRANSPORTATION SERVICE AGREEMENTS (continued)

October 2003.  The permanent release to Mirant commenced in December 2001
and the firm service agreements expire in October 2006 and December 2008.
The obligations of Mirant and PAGUS are supported by various credit sup-
port  arrangements  including  among  others,  letters  of  credit  and  escrow
accounts and an upstream capacity transfer agreement.  Operating revenues
from the Mirant and PAGUS firm service agreements and interruptible serv-
ice agreements for the years ended December 31, 2001, 2000 and 1999 were
$80.7 million, $78.2 million and $76.6 million, respectively.

Some of Northern Border Pipeline’s shippers are affiliated with its gen-
eral  partners.  Enron  North  America  (ENA),  a  wholly-owned  subsidiary  of
Enron, has firm service agreements representing 3.5% of capacity, a por-
tion of which (1.1%) has been temporarily released to a third party until
October  31,  2002  (see  Note  10).  Transcontinental  Gas  PipeLine
Corporation,  a  subsidiary  of  Williams,  holds  a  firm  service  agreement
representing 0.7% of capacity.  The firm service agreements with affil-
iates  extend  for  various  terms  with  termination  dates  that  range  from
October  2002  to  May 2009.    Operating  revenues  from  the  affiliated  firm
service agreements and interruptible service agreements, including rev-
enues  from  TransCanada  Energy  when  it  held  capacity  on  Northern  Border
Pipeline,  were  $52.1  million,  $58.5  million  and  $52.5  million  for  the
years ended December 31, 2001, 2000 and 1999, respectively.

quently exchanged in a registered offering for notes with substantially
identical terms (2001 Pipeline Senior Notes).  The proceeds from the 2001
Pipeline Senior Notes were used to reduce indebtedness outstanding under
the Pipeline Credit Agreement.  

In August 1999, Northern Border Pipeline completed a private offering of
$200  million  of  7.75%  Senior  Notes  due  2009,  which  notes  were  subse-
quently exchanged in a registered offering for notes with substantially
identical  terms  (1999  Pipeline  Senior  Notes).    Also  in  August  1999,
Northern  Border  Pipeline  received  approximately  $12.9  million  from  the
termination of interest rate forward agreements, which is being amortized
against interest expense over the life of the 1999 Pipeline Senior Notes.
The  interest  rate  forward  agreements,  which  had  an  aggregate  notional
amount of $150 million, had been executed in September 1998 to hedge the
interest rate on a planned issuance of fixed rate debt in 1999.  The pro-
ceeds  from  the  private  offering,  net  of  debt  discounts  and  issuance
costs, and the termination of the interest rate forward agreements were
used to reduce existing indebtedness under the Pipeline Credit Agreement.

In  June  1997,  Northern  Border  Pipeline  entered  into  a  credit  agreement
(Pipeline  Credit  Agreement)  with  certain  financial  institutions,  which
is comprised of a $100 million five-year revolving credit facility and a
$272 million term loan, both maturing in June 2002.  The Pipeline Credit
Agreement permits Northern Border Pipeline to choose among various inter-
est rate options, to specify the portion of the borrowings to be covered
by specific interest rate options and to specify the interest rate peri-
od, subject to certain parameters.  Northern Border Pipeline is required
to  pay  a  facility  fee  on  the  aggregate  principal  commitment  amount  of
$372 million.

Interest  paid,  net  of  amounts  capitalized,  during  the  years  ended
December 31,  2001,  2000  and  1999  was  $53.9  million,  $68.0  million  and
$55.5 million, respectively.

Aggregate  required  repayments  of  long-term  debt  are  as  follows:    $350
million  and  $65  million  for  2002  and  2003,  respectively.    There  are  no
required repayment obligations for either 2004, 2005 or 2006.

Certain of Northern Border Pipeline’s long-term debt and credit arrange-
ments  contain  requirements  as  to  the  maintenance  of  minimum  partners’
capital and debt to capitalization ratios which restrict the incurrence
of other indebtedness by Northern Border Pipeline and also place certain
restrictions  on  distributions  to  the  partners  of  Northern  Border
Pipeline.    Under  the  most  restrictive  of  the  covenants,  as  of  December
31, 2001 and 2000, respectively, $110 million and $136 million of part-
ners’ capital of Northern Border Pipeline could be distributed.

The  following  estimated  fair  values  of  financial  instruments  represent
the amount at which each instrument could be exchanged in a current

transaction between willing parties.  Based on quoted market prices for
similar issues with similar terms and remaining maturities, the estimat-
ed  fair  value  of  the  1992  Pipeline  Senior  Notes,  1999  Pipeline  Senior
Notes and 2001 Pipeline Senior Notes was approximately $623 million and
$404 million at December 31, 2001 and 2000, respectively.  Northern Border
Pipeline presently intends to maintain the current schedule of maturities
for  the  1992  Pipeline  Senior  Notes,  1999  Pipeline  Senior  Notes  and  the
2001  Pipeline  Senior  Notes,  which  will  result  in  no  gains  or  losses  on
their respective repayment.  The fair value of Northern Border Pipeline’s
variable  rate  debt  approximates  the  carrying  value  since  the  interest
rates are periodically adjusted to reflect current market conditions.

6.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

In  1998,  the  Financial  Accounting  Standards  Board  issued  SFAS  No.  133,
“Accounting for Derivative Instruments and Hedging Activities,” which was
subsequently  amended  by  SFAS  No.  137  and  SFAS  No.  138.    SFAS  No.  133
requires that every derivative instrument (including certain derivative
instruments embedded in other contracts) be recorded on the balance sheet
as either an asset or liability measured at its fair value.  The state-
ment requires that changes in the derivative’s fair value be recognized
currently in earnings unless specific hedge accounting criteria are met.
Special accounting for qualifying hedges allows a derivative’s gains and
losses to offset related results on the hedged item in the income state-
ment, and requires that a company formally document, designate and assess
the  effectiveness  of  transactions  that  receive  hedge  accounting.
Northern Border Pipeline adopted SFAS No. 133 beginning January 1, 2001.

As  a  result  of  the  adoption  of  SFAS  No.  133,  Northern  Border  Pipeline
reclassified approximately $11.1 million from long-term debt to accumu-
lated other comprehensive income related to unamortized proceeds from the
termination of interest rate swap agreements.  Also upon adoption of SFAS
No. 133, Northern Border Pipeline recorded a non-cash loss in accumulat-
ed other comprehensive income of approximately $0.8 million, related to
its  outstanding  interest  rate  swap  agreement  with  a  notional  amount  of
$40 million, which terminated in November 2001.

In  March  2001,  Northern  Border  Pipeline  entered  into  forward  starting
interest rate swaps with notional amounts totaling $200 million related
to  the  planned  issuance  of  10-year  and  30-year  fixed  rate  debt.    Upon
issuance  of  the  2001  Pipeline  Senior  Notes  in  September  2001,  Northern
Border Pipeline paid approximately $4.1 million to terminate the swaps,
which was recorded in accumulated other comprehensive income.  The swaps
were  designated  as  cash  flow  hedges  as  they  were  entered  into  to  hedge
the fluctuations in Treasury rates and spreads between the execution date
of the swaps and the issuance of the 2001 Pipeline Senior Notes.

During the year ended December 31, 2001, Northern Border Pipeline amor-
tized approximately $1.2 million related to the terminated interest rate

swap agreements as a reduction to interest expense from accumulated other
comprehensive  income.    Northern  Border  Pipeline  expects  to  amortize  a
comparable amount in 2002.

In November 2001, Northern Border Pipeline entered into forward starting
interest rate swaps with notional amounts totaling $150 million related
to  the  planned  issuance  of  five-year  senior  notes.  The  swaps  have  been
designated  as  cash  flow  hedges  as  they  were  entered  into  to  hedge  the
fluctuations in Treasury rates and spreads between the execution date of
the  swaps  and  the  issuance  date  of  the  senior  notes,  which  is  expected
to  occur  in  the  second  quarter  of  2002.  At  December 31,  2001,  Northern
Border Pipeline recognized a non-cash gain in accumulated other compre-
hensive income of approximately $3.4 million, with a corresponding amount
reflected in other assets on the accompanying balance sheet.

COMMITMENTS AND CONTINGENCIES

Capital expenditures

Total  capital  expenditures  for  2002  are  estimated  to  be  $12  million.
This includes approximately $2.5 million for Project 2000 (see Note 3).
Funds required to meet the capital expenditures for 2002 are anticipat-
ed  to  be  provided  primarily  from  debt  borrowings  and  operating  cash
flows.

Environmental Matters

Northern Border Pipeline is not aware of any material contingent liabil-
ities with respect to compliance with applicable environmental laws and
regulations.

Other

On  July  31,  2001,  the  Assiniboine  and  Sioux  Tribes  of  the  Fort  Peck
Indian  Reservation  (Tribes)  filed  a  lawsuit  in  Tribal  Court  against
Northern Border Pipeline to collect more than $3 million in back taxes,
together  with  interest  and  penalties.    The  lawsuit  relates  to  a  utili-
ties tax on certain of Northern Border Pipeline’s properties within the
Fort Peck Reservation.  Based on recent decisions by the federal courts
and other defenses, Northern Border Pipeline believes that the Tribes do
not have the authority to impose the tax and that the lawsuit will not
have a material adverse impact on Northern Border Pipeline.

Various  legal  actions  that  have  arisen  in  the  ordinary  course  of  busi-
ness are pending.  Northern Border Pipeline believes that the resolution
of  these  issues  will  not  have  a  material  adverse  impact  on  Northern
Border Pipeline’s results of operations or financial position.

ACCOUNTING PRONOUNCEMENTS

In  the  third  quarter  of  2001,  the  Financial  Accounting  Standards  Board
issued SFAS No. 143, “Accounting for Asset Retirement Obligations” and SFAS
No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.”

SFAS  No.  143  requires  entities  to  record  the  fair  value  of  a  liability
for an asset retirement obligation in the period in which it is incurred.
When the liability is initially recorded, the entity capitalizes a cost
by increasing the carrying amount of the related long-lived asset.  Over
time, the liability is accreted to its present value and the capitalized
cost is depreciated over the useful life of the related asset.  Upon set-
tlement of the liability, an entity either settles the obligation for its
recorded amount or incurs a gain or loss.  SFAS No. 143 is effective for
fiscal  years  beginning  after  June 15,  2002,  with  earlier  application
encouraged.  Northern Border Pipeline is in the process of evaluating the
application of this pronouncement. 

SFAS No. 144 establishes one accounting model to be used for long-lived
assets  to  be  disposed  of  by  sale  and  broadens  the  presentation  of  dis-
continued operations to include more disposal transactions.  SFAS No. 144
supersedes both SFAS No. 121, “Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed of,” and the accounting
and reporting provisions of APB Opinion No. 30.  This standard is effec-
tive for fiscal years beginning after December 15, 2001. Northern Border
Pipeline adopted SFAS No. 144 effective January 1, 2002. Northern Border
Pipeline does not expect the adoption of SFAS No. 144 to have a materi-
al impact on its financial position or results of operations.

RELATIONSHIPS WITH ENRON

In December 2001, Enron and certain of its subsidiaries filed voluntary
petitions for Chapter 11 reorganization with the U.S. Bankruptcy Court.
Northern Plains was not included in the bankruptcy filing and management

operational  and  administrative  service  obligations  under  the  existing

RELATIONSHIPS WITH ENRON (continued)

operating  agreement.    ENA,  a  subsidiary  of  Enron,  was  included  in  the
bankruptcy filing.  As indicated in Note 4, ENA has firm service agree-
ments representing approximately 3.5% of contracted capacity, a portion
of  which  (1.1%)  has  been  temporarily  released  to  a  third  party  until
October 31, 2002.  Northern Border Pipeline recorded a bad debt expense
of  approximately  $1.3  million  representing  ENA’s  unpaid  November  and
December 2001 transportation, which is included in operations and main-
tenance  expense  on  the  statement  of  income.    ENA  has  not  assumed  or
rejected  these  contracts,  but  its  ability  to  use  the  capacity  has  been
suspended  until  ENA  provides  adequate  assurance  of  credit  support  and
payment.  The third party that holds the 1.1% of capacity through October
31, 2002 has filed a complaint with the FERC requesting, in effect, that
its  contract  be  deemed  terminated  as  a  consequence  of  ENA’s  filing  for
bankruptcy protection. Management believes this shipper’s contract will
remain in effect until October 31, 2002. For 2002, the estimated finan-
cial exposure for ENA’s firm service agreement is approximately $9 mil-
lion.  Management believes that even if ENA continues to fail to perform
its  obligations  under  the  firm  service  agreements,  it  will  not  have  a
material  adverse  impact  on  Northern  Border  Pipeline’s  financial  condi-
tion and results of operations.  

Management  plans  to  continue  to  monitor  developments  at  Enron,  to  con-
tinue  to  assess  the  impact  on  Northern  Border  Pipeline  of  its  existing
agreements  and  relationships  with  Enron  and  to  take  appropriate  action
to protect the interests of Northern Border Pipeline.

SUBSEQUENT EVENTS

Northern  Border  Pipeline  makes  distributions  to  it  general  partners
approximately  one  month  following  the  end  of  the  quarter.    The  distri-
bution for the fourth quarter of 2001 of approximately $39.2 million was
paid February 1, 2002.

on dated January 22, 2001. Our audits were made for the purpose of forming an
opinion  on  the  basic  financial  statements  taken  as  a  whole.  The  schedule  of
Northern Border Pipeline Company listed in Item 14 of Part IV of this Form 10-
K is the responsibility of the Company’s management and is presented for pur-
poses of complying with the Securities and Exchange Commission’s rules and is
not  part  of  the  basic  financial  statements.  This  schedule  has  been  subjected
to the auditing procedures applied in the audits of the basic financial state-
ments  and,  in  our  opinion,  fairly  states  in  all  material  respects  the  finan-
cial data required to be set forth therein in relation to the basic financial
statements taken as a whole.
