*Quarterly earnings per share are based upon the average number of common shares outstanding 
during each quarter. Because the average number of shares outstanding has changed in each  
quarter shown, the sum of quarterly earnings may not equal earnings per share for the year.  
Variations in earnings between quarterly periods are due primarily to the seasonal nature of  
the Company’s business.

Ahead of

the curve

The right source of energy affects so 

many lives in so many ways. By providing 

the best in natural gas service, NW Natural 

enhances the lives of everyone from chefs, 

to swimmers, to children playing in the 

park. In 2004, even horses stood to benefit.

Because we manage our business ahead 

of the curve, we put our customers a step 

ahead as well.

Letter to Shareholders

Earning
the right to grow

Mark Dodson, President and CEO, at the site of the Sherwood, Oregon, intertie of the South Mist Pipeline Extension. 
Completed five weeks ahead of schedule, it was the largest capital project in company history and is now included in  
Oregon and Washington rates.

T o Our Shareholders:

In 2004, the years of planning and 

hard work paid off.
  NW Natural saw the culmination of 
several landmark construction projects 
and key regulatory changes. Each  
required years of planning and analy-
sis. Each demanded solid execution. 
Each added to our earnings and cash 
flows in 2004 and will continue to in-
crease our value in the years ahead.
  NW Natural has dedicated itself  
to getting ahead of the curve and has 
succeeded in many ways. The evidence 
of that can be seen not just in the 
Company’s 2004 performance but  
also in the strong platform for growth  
it has created for 2005 and beyond.

Highlights of the year
In 2004, NW Natural:

■  Earned $1.86 a diluted share, com-
pared to $1.76 in 2003, a solid 5.7  
percent increase;

2

■  Completed the South Mist Pipeline 
extension — and began recovering its 
costs in rates;
■  Successfully completed a general  
rate case in Washington;
■  Began serving customers in Coos 
County, Oregon;
■  Offset most of the negative impacts 
of warm weather and conservation 
through the new Weather Adjusted 
Rate Mechanism and the Conservation 
Tariff;
■  Reached an agreement in Oregon  
to recover and earn on investments 
needed to comply with federal pipeline 
integrity rules;
■  Negotiated a new five-year labor 
agreement;
■  For the 18th year in a row,  
achieved an annual customer  
growth rate of more than 3 percent; 
and
■  Increased annual dividends paid  

to shareholders for the 49th 
consecutive year.
Milestone projects completed
In 2004, we proved that great 
planning brings results—especially 
when it’s followed by great execution. 
We demonstrated this with the 
completion of two long-term initiatives: 
a 40-year dream to bring natural  
gas over the Oregon Coast Range  
to Coos County, and the more-than- 
six-year pursuit of a 61-mile extension 
of the South Mist Pipeline. Both 
projects open new doors for customer 
growth and bring returns on our  
capital investments.
  We completed the South Mist 
Pipeline Extension weeks early, and  
its costs were rolled into rates in both 
Oregon and Washington. That we 
achieved this milestone without a 
significant hitch is a testament to  
our project management abilities.

 
 
  Farther south, NW Natural created  
a backbone distribution system for  
four cities in Coos County. When the 
County needed to replace its contractor 
building the transmission line connect-
ing to our system, we stepped up to 
help, providing project management 
support to oversee the county pipe-
line’s completion. The Company began 
recovering the cost of the Coos Bay 
distribution system in November.

Regulatory strategies prove  
their value
  While NW Natural was planning 
system expansions, it also was prepar-
ing to strengthen and stabilize its 
revenues. Regulatory changes that took 
effect in the previous two years showed 
their value in 2004.
  The Conservation Tariff, approved by 
the Public Utility Commission of Oregon 
in 2002, earned the Company national 
recognition last year. The Weather 
Adjusted Rate Mechanism (WARM), 
which took effect in Oregon in 2003, 
added 20 cents per share by helping to 
compensate for weather in 2004 that 
was 8 percent warmer than average.
  Support by Oregon regulators  
for these strategies has helped NW 
Natural overcome two of the greatest 
challenges facing utilities today—
uncertainty from weather and lower 
per capita consumption.
  Also in 2004, Oregon regulators 
approved our request to include the 

costs of complying with federal pipe-
line integrity regulations in our rates. 
The decision allows us both to recover 
and earn on pipeline integrity invest-
ments that will be made in the  
coming years.
  With these rate mechanisms in 
place, NW Natural is in an excellent 
position to focus its efforts on gaining 
more customers, more profitably.

More customers, greater 
profitability
  NW Natural grew its customer  
base by more than 3 percent in 2004, 
double the average of local distribution 
companies nationally. Even more 
significantly, the Company continued 
to increase the value added by each 
new customer. Profitability of new resi-
dential customer acquisitions increased 
from 14 percent in 2003 to 17 percent 
in 2004, and customer growth added 
approximately $7 million to margin.
  Our drive for lower costs and 
enhanced customer profitability was 
boosted further when regulators in 
Oregon and Washington gave us 
greater flexibility in responding to gas 
service requests for new development. 
We call it the Open Pathway program. 
Now, builders and developers must 
provide a pathway—an open trench or 
conduit—for service lines and mains. 
We expect this program to cut in half 
the cost of conventional service 
connections, providing savings that

will allow us to reach even more 
customers, more profitably.
  Last year, NW Natural adopted a 
new software package, Prospector Pro, 
which added consistency and disci-
pline to our evaluation of requests for 
new gas service. In addition, we started 
using a computerized Assumed Return 
on Equity (AROE) Study to identify 
new neighborhoods to target for 
growth. AROE can help the Company 
reduce investment risk while proactive-
ly seeking new customers.

It is one thing to add large numbers 

of new customers; it is another to 
deliver great service.
  Customer satisfaction continues to 
be a top priority for NW Natural. We 
were pleased to learn that we ranked 
ninth out of 55 gas utilities nationally 
in J.D. Power’s 2004 Gas Utility Resi-
dential Customer Satisfaction Study. 
The Company ranked first in the West 
and second in the nation on billing  
and payment.

Employees get it done
  The year 2004 started out with ice 
storms and record-breaking demand  
for natural gas, creating a showcase  
for NW Natural’s employees.
  Only about 60 of more than 580,000 
customers experienced outages, and 
those for only a few hours. Employees

customer growth remains strong and is 
increasingly profitable. And our inter-
state storage business, which has newly 
added capacity, remains a growth 
opportunity we expect to add signifi-
cantly to our bottom line in the future.
  As importantly, with weather 
normalization and the Conservation 
Tariff, the foundation we’ve created is 
largely protected from warmer-than-
normal weather and declining 
consumption due to conservation.
  We enter 2005 as purposeful as ever. 
We know who we are. We know where 
we’re going. We know what you expect 
from us, and we know how to deliver.
  This year we will keep looking 
ahead, managing our costs, excelling  
at business basics and adding 
customers profitably. In short, we  
will be unwavering in our focus on  
the core business.
  But that doesn’t mean we won’t 
look out at the horizon as well. We  
will continue to search for new growth 
opportunities. In the same way we 
pursued underground storage, then 
leveraged the Mist storage field to 
create an interstate storage business, 
we will keep looking for ways to build 
on our core strengths.
  We’re ready for the challenges, and 
the opportunities. After 146 years of 
excellence, we’re ahead of the curve —
and we intend to stay there.

Sincerely,

Mark S. Dodson
President and Chief Executive Officer

adjusted valves, climbed roofs to  
clear vents and helped stranded 
motorists. Some employees didn’t 
make it home for three days, staying 
near the Portland office to make sure 
the phones got answered.
  Although the weather let up within 
a week, our employees never did.

In every part of the Company, our 
employees stepped forward to get the 
tough things done. A great example is 
the year-long effort to comply with  
the Sarbanes-Oxley Act. Our finance 
and accounting departments, along 
with a host of others across the 
Company, worked tirelessly to comply 
with the act. Our outside auditor,  
PricewaterhouseCoopers LLP, agreed 
with management’s assessment that  
in fact we did.

In a year when we were once again 
named one of Oregon’s 100 Best Places 
to work by Oregon Business Magazine, 
we also reached agreement on a five-
year contract, called the Joint Accord, 
with members of the Office and 
Professional Employees International 
Union, Local 11. It is a balanced 
agreement that advances the interests  
of the Company and its employees.

The challenges ahead
  High gas prices are of great concern, 
both to us and to our customers. 
Locally, NW Natural is doing what it 
can to offset high prices.

In 2004, as part of a disciplined  

gas purchasing strategy, we used  
our Mist underground storage to 
maximum advantage, buying supplies 
when prices were most favorable. As  
a result, today our weighted average 
cost of gas is the lowest in Oregon  
and Washington.
  Our Conservation Tariff has aligned 
shareholder and customer interests 
around energy efficiency, and we are 
actively working with the Energy Trust 
of Oregon to help customers use 
natural gas as efficiently as possible.  
In 2005, we will be working to renew 
this innovative tariff. We have commis-
sioned a study of the tariff that will 
serve as a basis for a filing this year  
to continue the mechanism.
  As a local distribution company,  

4

we are price takers, not price makers 
when it comes to wholesale natural  
gas prices. Our challenge is to demon-
strate to customers that they receive 
superior value from our products and 
services. And we’re doing that in a 
number of ways. We’re strengthening 
our energy efficiency communications, 
unveiling an improved web site that 
offers useful tools such as a bill analyz-
er and reorganizing our consumer call 
centers for faster, easier solutions and a 
better customer experience.

We enter 2005 as 
purposeful as ever. 
We know who  
we are. We know 
where we’re going. 
We know what you 
expect from us,  
and we know  
how to deliver.

  At the national level, we see some 
hopeful signs of progress in addressing 
the supply imbalance that exists today. 
These include the increasing number  
of liquefied natural gas import proposals 
moving through the permitting process 
and new incentives passed by Congress 
to build an Alaskan pipeline.
  Clearly, the country needs a compre-
hensive energy strategy. NW Natural 
will work closely this year with the 
American Gas Association to advance 
national energy policies aimed at 
reducing gas price volatility.

Around the next curve
  While we are proud of what the 
years of planning and hard work meant 
to our performance in 2004, we are 
even more excited about what they 
mean for 2005 and beyond.
  We have built a strong foundation 
on which to grow our Company. The 
South Mist Pipeline Extension and the 
Coos Bay distribution system are in 
rates and contributing to our earnings. 
We can now recover and earn on our 

 
 
 
Focusing
on mutual gains

Interview with
Gregg Kantor,
Senior Vice President

1. What is NW Natural’s regulatory strategy, and how 
has the Company been pursuing it?
  A major focus has been reducing business risks from 
factors outside the Company’s control. To that end, we’ve 
introduced a number of innovative regulatory mechanisms, 
each built on our commitment to meet the needs of both 
customers and shareholders.
  For example, when natural gas prices increased significant-
ly in 2000 and 2001, we stepped forward to help customers 
use our product more efficiently. But as usage declined so 
did our revenues.

It made no sense that doing what was right for customers 
should hurt the company. So we developed a mechanism we 
called the Conservation Tariff. In 2002, the Public Utility 
Commission of Oregon (OPUC) approved the Conservation 
Tariff, which partially decouples our margins from how 
much gas we sell. In the end, it aligns the interests of 
shareholders with those of customers.
  Weather is a challenge we’ve faced for a long time. In 
2003, we developed our own weather normalization 
mechanism, called the Weather Adjusted Rate Mechanism 
(WARM). With the backing of customer groups, we secured 
approval from the OPUC. WARM helps protect customers 
against high gas bills during unusually cold winters and 
protects shareholders from revenue losses during unusually 
warm winters.
  Both the Conservation Tariff and WARM demonstrate 
what can be accomplished when solutions create a win for 
customers and shareholders.

2.  How have pipeline safety issues impacted your 
regulatory efforts?
  NW Natural has taken a proactive approach to pipeline 
safety. We completed removal of all cast-iron pipe in our 
system several years ago and are now replacing bare-steel 
pipe. The OPUC has supported these efforts by allowing  
the recovery of a substantial portion of the costs associated 
with the cast-iron pipe and bare-steel work.
  The new federal pipeline safety mandates increased 
significantly the work to be done on transmission lines.  
The cost of complying with these new requirements is a 
major concern to every gas utility. However, we have 
secured OPUC approval for the next four years to roll  
yearly pipeline integrity costs, including return, into rates 
each October.

3. What are the Company’s newest regulatory  
initiatives?

In late 2004, the Washington and Oregon commissions 
approved our Open Pathways tariff. This mechanism holds 

Gregg Kantor, Senior Vice President of Public and Regulatory 
Affairs, at the state capitol in Salem, leads the team that 
works with regulators in Oregon and Washington.

the customer responsible for providing a pathway for gas 
lines to new buildings or developments. The customer is 
required to make a trench or conduit available for gas 
services or mains or compensate the Company for its 
excavation time. This reflects requirements already in place 
for electric service and represents a major breakthrough for 
us. We expect it will cut in half the cost of installing service 
installations where joint trenching isn’t being used.

In January 2005, the OPUC approved a combined 
heat and power tariff. This tariff allows NW Natural to  
sell natural gas at a discounted rate to fuel microturbines, 
fuel cells and other small-scale electrical generating 
equipment. We hope this incentive will stimulate interest 
from both manufacturers and customers in these energy-
saving technologies.

4. How would you describe your relations with Oregon 
and Washington regulators and consumer advocates?
  Our relationships are quite positive. We are fortunate to 
have regulators and consumer advocates who, while tough 
and passionate about their duties, are also knowledgeable, 
fair and open-minded. They understand utilities must attract 
investment capital if they are to maintain safe, reliable 
service, and they are open to pursuing ideas that benefit 
customers while keeping utilities strong.

Ahead of
the curve

  Maybe “innovative” isn’t the first word that comes to mind 

when you think of a natural gas utility.

  But think again.

  Like most gas utilities, NW Natural is focused on providing  

safe, reliable, low-cost natural gas service to its customers.

It’s how we do it that stands out.

  We’re not afraid to try new approaches to meet customers’ 

needs. There’s the new mechanism we developed to help 

customers keep their bills down when weather is colder than 

normal... the new energy systems we’ve developed to increase 

efficient use…even the month-early completion of a pipeline 

expansion, which made the critical difference in assuring reliable 

service to customers like the University of Oregon during the bitter 

winter storm of January 2004.

  We’re a natural gas utility — but we’re also bold enough to 

innovate and bold enough to lead. That’s what puts us ahead  

of the curve.

Opening
new markets

  Some dreams refuse to die. For 39 years, NW Natural 
held fast to its vision of serving Coos Bay, a Southern 
Oregon coast community for which the Company held  
a franchise.

In 2004, that dream came true.

  There were plenty of ups and downs in building 
public support, securing funding and coordinating 
construction of NW Natural’s distribution system with 
the completion of the county’s transmission line. It took 
a commitment of dollars from the Oregon Legislature 
and a vote of Coos County residents to bring a 
transmission line across the Oregon Coast Range.
  But despite the obstacles, in 2004 NW Natural 
installed its new Coos County distribution system, 
comprising more than 250,000 feet of pipeline.
Building the backbone
  NW Natural started building its local distribution 
system in Coos County in August 2003. At the same 

time, the county began building the transmission line to 
connect Coos County customers to the interstate pipeline.
  NW Natural outpaced the county’s progress, and the 
local distribution system was ready to go by summer. 
Before the transmission line was completed, NW Natural 
began serving customers with trucked-in compressed 
natural gas.
  By November, 12 customers identified as having  
the most pressing need for natural gas were receiving 
supplies trucked from Portland in CNG tankers. 
NW Natural began to recoup through rates its Coos 
County investment of nearly $12 million.
Finally, the connection
  On Jan. 14, 2005, the county’s transmission line  
was ready for use. Coos County contractors had tested 
the line, and soon natural gas was flowing from the 
interstate pipeline to Coos County.

NW Natural Customer Consultant Linda 
Kennedy and Commercial Service Technician 
Dan Hutchens are key participants in the 
Company’s efforts to attract and serve  
more customers in the Coos Bay area.  
“It’s exciting and fun,” said Hutchens.  
“Coos County has had one of the highest 
unemployment rates in the state. I think 
once people see things starting to happen 
and new businesses coming in, they’ll 
understand why the county commissioners 
have been wanting to do this.” At right, 
restaurant  owner Elizabeth Kinzie looks 
forward to cooking with natural gas.

  Several weeks after gas was flowing, NW Natural  
had more than 400 homes and businesses signed up for  
gas service.
  The Company set a goal of serving 1,000 customers 
in the cities of Coos Bay, Myrtle Point, Coquille and 
North Bend by the end of 2005.
Under the bay
  One of the milestones in building the Coos Bay 
distribution system was crossing under Coos Bay  
to bring gas to the North Spit industrial area. The  
promise of natural gas already helped sway the  
decision of Southport Forest Products, which plans  
to build an expanded plant on the spit. In addition, 
Energy Products Development, LLC announced plans  
to build a liquefied natural gas plant on the spit 
specifically to take advantage of new gas lines to  
that area.

Leading
with innovation

  New technologies are providing new ways for 
customers to use energy wisely and for NW Natural  
to grow.
Combined heat and power
  NW Natural is a regional leader in promoting 
distributed generation and combined heat and power 
(CHP) projects. Distributed generation means the small-
scale generation of electricity at the location of its use 
rather than at a centralized power plant. CHP systems 
go a step farther by capturing waste heat from the 
generating process and using it to heat space or water. 
CHP is one of today’s most efficient and cost-effective 
ways to generate energy.
  NW Natural is a central player in a consortium of 
organizations and businesses promoting distributed 

generation and CHP. The Company’s newest project, to 
be completed in 2005, is a five-microturbine system at 
an Oregon Health Sciences University building.
  NW Natural anticipates long-range business  
benefits from promoting distributed generation and  
CHP. First, CHP offers NW Natural new ways to serve 
industrial customers. Second, CHP reduces the use  
of inefficient, centralized electric generation. This,  
in turn, reduces the demand for natural gas to  
generate electricity.

In 2004, the Public Utility Commission of Oregon 
approved a tariff proposed by NW Natural that will 
provide rate incentives for industrial customers using 
gas-powered distributed generation. The Company 
foresees an increase in the demand for onsite generation 

10

 
as electric rates go up and generating equipment costs 
come down.
Prospecting for profitability
  To make sure customer growth benefits the 
Company’s bottom line, NW Natural uses innovative 
tools to target its marketing and infrastructure 
investments. Two programs, Prospector Pro and  
AROE (Assumed Return on Equity), are NW Natural’s 
newest electronic tools for ensuring profitable growth.
  Prospector Pro, adopted in August 2004, allows  
NW Natural’s marketing representatives to calculate 
more accurately the cost of hooking up a new customer.  
With Prospector Pro, a marketing representative can 
estimate how much gas the new customer will use and 
then calculate costs and benefits. The program adds 
accuracy, consistency and discipline to 
customer acquisition efforts.

  While Prospector Pro responds to service requests, 
NW Natural uses AROE for proactive marketing. Using 
tax assessor data, an employee can estimate a home’s 
gas usage. AROE then overlays data from NW Natural’s 
propensity study to learn which homeowners are most 
likely to switch to natural gas.
  Now, NW Natural can focus direct mailings on 
neighborhoods with high percentages of likely, 
profitable customers. AROE also guides the selection  
of existing neighborhoods for new main construction.
We’ll call you back

In November, NW Natural became the first utility  
in our region to offer customers the option of receiving  
a call back, rather than waiting on hold to talk with  
a service representative. The launch of Virtual Hold 
Technology software won rave reviews from 

customers who were freed from waiting  

on their telephones but could still  
count on talking soon with a NW 

Natural employee. During 

November and December, just 
under half our customers chose 
the callback option.

College’s Swim Pavilion, now heated by a

Galati, NW Natural’s Director of Conservation 
and Technology, coordinated placement of the 
30 kW microturbine in the Portland college’s 
newest building, where it generates electricity 
for the campus. Waste heat from the 
microturbine warms the water in the pool.

11

 
Promoting
wise energy use

The Wall Street Journal subsequently featured an article 
on the mechanism and the unusual consumer-corporate 
partnership behind it.
  Cavanagh later joined NW Natural in advocating  
the tariff to the Washington Utilities and Transportation 
Commission. At the same time, the Company described 
to Washington regulators the Weather Adjusted  
Rate Mechanism (WARM), another innovative 
regulatory mechanism, which took effect in Oregon  
in October 2003.

 NW Natural introduced WARM as a way to help 

protect customers from extremely high bills when 

In 2004, investor-owned utilities around the nation 

turned to NW Natural for a potential solution to a 
chronic problem: How can we encourage customers  
to use energy more efficiently without reducing 
Company revenues?
  NW Natural’s Conservation Tariff, launched in 2002, 
recognizes that customers are using less natural gas  
as appliances become more efficient and as gas prices 
increase. The tariff provides a mechanism for protecting 
Company earnings as natural gas use declines. In 2004, 
it added $3.5 million to earnings, translating to 7 cents  
a share.
  By protecting earnings, the Conservation Tariff frees 
NW Natural to promote more aggressive energy 
efficiency programs. In 2004, NW Natural worked  
with the Energy Trust of Oregon to deliver high-
efficiency programs to reduce natural gas use by  
more than a million therms.
  One of NW Natural’s Conservation Tariff’s most vocal 
supporters is Ralph Cavanagh of the Natural Resources 
Defense Council. In the summer of 2004, Cavanagh  
and NW Natural President and CEO Mark  
Dodson addressed a national conference  
of state regulators to discuss the tariff’s  
benefits for consumers and utilities.

winter weather is colder than expected, and to help 
protect shareholders from reduced Company revenues 
when winter weather is warmer than normal. Unlike 
many parts of the country, utility weather normalization 
is not common in the Pacific Northwest.
  Consumer advocates supported WARM because they 
understand how it helps protect consumers from high 
winter bills. They also like the fact that the Company’s 
unique proposal trues up bills immediately, thus giving 
customers relief on their next bills. Most utilities don’t 
apply weather adjustments to customer bills until the 
following heating season.

               WARM played an important role in the 
Company’s financial results for the year,  

and especially for the second quarter 
of 2004, which was 31 percent 

warmer than 

average. For 
the year, 
WARM 
contributed 

$9 million of 

margin, equivalent to 20 cents a share.

Building for
the future

It was another milestone year for Mist, NW Natural’s 

premium underground gas storage facility.

In the 1970s, when NW Natural began preparing  

the Mist storage field, management could not have 
envisioned all the benefits the Company’s investment 
would yield. Nor could they know how underground 
storage would give them more control over peak-
demand gas supplies and future gas costs.
  By 2004, the decision to invest at Mist has never 
looked better. Last fall, the Company completed the 
biggest capital construction project in its history: a  
61-mile extension of the South Mist pipeline, expanding 
Mist’s takeaway capacity and bolstering the Company’s 
service to its fast-growing customer base.
  Underground storage supplements NW Natural’s gas 
supplies in high-demand periods. It also allows the 
Company to reduce its need for year-round interstate 
pipeline capacity, and provides a way for NW Natural  
to purchase and store gas when prices are lowest.

  NW Natural also sells gas storage services on the  
interstate market. In this way, the Company has  
diversified its revenue streams while leveraging its  
core assets and expertise.
SMPE finale
  After six years of planning, permitting and construc-
tion, the South Mist Pipeline Extension (SMPE) officially 
went on line on Sept. 22, 2004. The Company rolled 
SMPE into rates on Oct. 1. Built for about $110 million, 
the 24-inch-diameter SMPE doubles deliverability from  
the Mist underground storage field to the Portland 
metropolitan area and provides another connection to 
the interstate pipeline.
  Construction was a major challenge, as the pipeline 
crossed sensitive environmental areas, rich farmland 
and populous suburbs. Yet the team completed the 
project five weeks ahead of schedule after contractors 

14

 
 
successfully managed the longest large-diameter 
underground bore in Oregon history. The bore passed 
through more than a mile of solid rock, but it was 
finished ahead of schedule and on budget.
Timing is everything
  The SMPE’s first 11.7-mile segment began operating 
Nov. 6, 2003. On Jan. 5, 2004, extremely cold tempera-
tures sent gas demand soaring, and NW Natural set a 
new one-day sendout record of 8.9 million therms.  
The new pipeline was critical to the Company’s ability 
to avoid outages and reliably serve its customers.
  The SMPE helps NW Natural serve some of Oregon’s 
fastest-growing communities. Its completion puts 
NW Natural ahead of demand, allowing it to absorb  
new residential, commercial and industrial customers  
in both suburban and rural areas near Portland.
Jewels in the making
  The year included improvements to the Mist storage 

facilities as well. In 2004, NW Natural completed the 
expansion of its Sapphire phase. This $9.1 million 
project expanded capacity and deliverability of the  
Mist facilities. Sapphire’s immediate purpose is to  
make new storage capacity available for the interstate 
market. As NW Natural’s core market grows, the 
Company expects to reallocate Sapphire’s resources  
to serve its core distribution customers.
Interstate customer growth
  As NW Natural continues to develop storage 
infrastructure, it also expands its interstate business. 
The Company currently has 10 interstate storage 
customers across the Western United States and  
Canada, with customers on both firm and interruptible 
service contracts. Customers include local distribution 
companies, energy marketers and power generators.

Among the residents Senior Project 
Engineer Roy Rogers wanted to keep 
happy during SMPE construction were 
some four-legged ones. NW Natural 
conducted extensive research and 
worked with equestrian facilities like 
Sherwood Forest in Wilsonville, Oregon, 
to assure that neither the construction nor 
the new pipeline would disturb the horses. 
Rogers and the construction team also 
restored horse pastures and paths to 
their previous condition – or better.

Profiting from
smart growth

Jamison Park draws visitors of all ages to the heart 
of Portland’s new River District, a bustling 
community of upscale as well as affordable multi-
family housing, cafes, shops, boutiques and 
galleries, nearly all served by NW Natural. Brenda 
Hartzog, Residential New Construction Consultant, 
and Grant Yoshihara, Director of Utility Services, 
help bring natural gas service to the homes and 
businesses in this thriving neighborhood.

16

  NW Natural is benefiting from strengthened relation-
ships with architects, engineers and developers. The 
Company reaches out to these groups through seminars 
and newsletters to educate them about economical and 
space-saving natural gas technology. Finally, the 
Company’s efforts to target idle services are returning 
some commercial buildings back to gas service.
Open pathways reduce construction costs
  For years, builders and homeowners in the Northwest 
have been required to provide a trench to bring 

electricity to new buildings. This 
has not been the case with natural 
gas. That changed in 2004, when 
Oregon and Washington regu-
lators agreed to require customers 
to provide an open trench or 
conduit for natural gas service 
lines and mains to new buildings.
This means NW Natural will 

lower its costs and realize higher margins from all new 
construction. While sharing trenches with electric and 
telecommunication providers already is common 
practice in many parts of the service territory, each year 
crews are required to dig an estimated 7,000 trenches to 
install gas services. NW Natural’s contribution to the 
cost of residential service installation is expected to fall 
from an average $726 to $339.
  As an added incentive, NW Natural now offers a 
guaranteed installation date when a contractor notifies 
the Company in advance that a pathway will be ready 
for our pipeline.

  Natural gas is still the fuel of choice in the Northwest, 
and NW Natural has the customer growth to prove it.

In 2004, the Company’s customer base grew by more 

than 3 percent for the 18th consecutive year. At the 
same time, the Company continued to improve the 
profitability of its customer additions.
The growing multifamily sector
  Because of Oregon’s unique land use planning 
system, Portland is growing up, not just out. With 
suburban development contained by a conservative 
urban growth boundary, high-density multifamily 
construction is the hottest trend in Portland’s  
housing market.
  To help attract empty nesters and young professionals 
to townhouses and condominiums, developers are 
investing in natural gas space and water heating as  
well as cooktops and hearths. In 2004, NW Natural 

significantly exceeded its goals for  

new multifamily services.

Affordable housing 

developers prefer gas, too
      High-end developers aren’t  
the only ones choosing gas. 
Developers of affordable housing 
have realized that high-
efficiency natural 

gas appliances can reduce tenants’ fuel 
bills. New natural gas technologies such 
as compact on-demand water heaters 
save space as well as energy.

In 2004, the Portland Develop-
ment Commission (PDC) updated 
its “Green Building” guidelines. 
Affordable projects receiving PDC 
funds are encouraged to use 
high-efficiency combo systems 
and natural gas furnaces.
Commercial conversions 

present new opportunities
  Although new commercial development has been 
slow to improve, NW Natural has seen an increase 
in commercial conversions. With the limited 
supply of buildable land in the Portland 
area, developers are renovating existing 
buildings rather than constructing new 
ones. These renovations often include  
a switch to natural gas.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

  The following is management’s assessment of Northwest Natu-
ral Gas Company’s financial condition including the principal fac-
tors that affect results of operations. The discussion refers to the 
consolidated activities of the Company for the three years ended 
Dec. 31, 2004. Unless otherwise indicated, references in this dis-
cussion to “Notes” are to the notes to the consolidated financial 
statements in this report.
  The consolidated financial statements include the regulated par-
ent company, Northwest Natural Gas Company (NW Natural), and 
its non-regulated wholly-owned subsidiaries:
■  NNG Financial Corporation (Financial Corporation), and its 
wholly-owned subsidiaries
■  Northwest Energy Corporation (Northwest Energy), and its 
wholly-owned subsidiary
  Together these businesses are referred to herein as the “Com-
pany.” In this report, the term “utility” is used to describe the Com-
pany’s regulated gas distribution business and the term “non-util-
ity” is used to describe its interstate gas storage business and other 
non-regulated activities (see Note 2).

In  addition  to  presenting  results  of  operations  and  earnings 
amounts in total, certain measures are expressed in cents per share. 
These amounts reflect factors that directly impact earnings. The 
Company believes this per share information is useful because it 
enables readers to better understand the impact of these factors on 
earnings. All references in this report to earnings per share are on 
the basis of diluted shares (see Note 1).

EXECUTIVE SUMMARY
  The Company’s strategy in 2004 was to strengthen its financial 
position and remain focused on profitably growing its regulated 
gas distribution business and interstate gas storage business.
  Highlights of 2004 include:
■  overall earnings growth of 11 percent over 2003 despite weather 
conditions that were 3 percent warmer;
■  the addition of 18,485 customers, for a growth rate in excess of 
3 percent for the 18th consecutive year;
■  the issuance of $40 million in common stock through a public 
offering to help fund major construction projects and maintain a 
balanced capital structure;
■  the upgrade of the Company’s long-term debt rating to A+ by 
the Standard & Poor’s Rating Services;
■  the completion ahead of schedule of the Company’s largest 
construction project to date, the 61-mile South Mist Pipeline Ex-
tension (SMPE), which received timely regulatory approval for 
recovering its costs through customer rates in both Oregon and 
Washington;
■  regulatory approval to track future pipeline integrity manage-
ment costs into rates in Oregon;
■  a new 5-year labor agreement, also known as the Joint Accord;
■  the settlement and early implementation of the Washington 
general rate case;
■  expansion of the Company’s gas distribution system into Coos 
County, Oregon, an area targeted for natural gas service for over 
three decades; and
■  the development of additional gas storage capacity at Mist for 
interstate storage services, replacing capacity that had been re-
called to meet core utility customer requirements.
Issues, Challenges and Performance Measures
  There are a number of factors that affect the Company’s opera-
tions and financial performance. The most significant issues and 
challenges the Company expects to face in 2005 include high gas 
commodity prices, unpredictable weather conditions, the impact 
of regulatory actions or policy changes, managing gas supplies and 
storage capacity, maintaining a competitive advantage over alter-

18

nate fuels, managing environmental risks and exposures, an un-
certain economic recovery and higher interest rates. For a detailed 
listing of other risks facing the Company, see “Forward-Looking 
Statements” and “Quantitative and Qualitative Disclosures About 
Market Risk,” below.

In order to deal with these and other issues affecting the busi-

ness, the Company’s strategic plan includes strategies for:
■  improving NW Natural’s ability to add customers both profit-
ably and at a rapid pace;
■  maintaining NW Natural’s reputation for exemplary service;
■  reducing business risk;
■  managing all costs, including capital expenditures;
■  setting high performance standards for all employees; and
■  judiciously growing beyond the Company’s local distribution 
business where such growth would complement core assets  
and competencies.

In addition to return on equity (ROE) and common equity ratio 
as key indicators of the Company’s operating performance and fi-
nancial condition, other key performance measures the Company 
uses in monitoring progress against its goals are utility earnings 
per share, customer satisfaction ratings, new customer additions, 
operations and maintenance expense per customer, construction 
cost per meter installed, and non-revenue producing capital expen-
ditures per customer.

EARNINGS AND DIVIDENDS
  Earnings  applicable  to  common  stock  were  $50.6  million,  or 
$1.86 a diluted share, for the year ended Dec. 31, 2004, compared 
to $45.7 million, or $1.76 a share, and $41.5 million, or $1.62 a 
share, for the years ended Dec. 31, 2003 and 2002, respectively. Re-
turns on average common equity for these three years were 9.4 
percent, 9.3 percent and 8.7 percent, respectively. Primary factors 
affecting earnings, and the re-
sulting positive (negative) im-
pact include:
2004 compared to 2003:
■  increased the contribution 
to net operating revenues  
(margin) from residential 
and commercial customers 
primarily resulting from  
the Oregon and Washington  
general rate increases,  
including rate increases  
for the SMPE investment 
and a full year effect of  
the weather normalization 
mechanism – $26 million;
■  increased margin contri-
bution from industrial  
customers resulting from 
rate redesigns in the 2003 
Oregon general rate case and a recovering economy –  
$4.8 million;
■  decreased margin from other utility operating revenues due to 
changes in and amortizations under the Company’s regulatory 
deferral mechanisms – ($7.8 million);
■  increased franchise tax expense due to higher gross revenues – 
($2.2 million);
■  increased payroll and related payroll tax, pension and health 
care costs primarily due to wage and salary increases and certain 
benefit cost increases – ($4.6 million);
■  internal development costs and external audit fees relating to 
the implementation of Section 404 of the Sarbanes-Oxley Act of 

Diluted earnings were $1.86 
per share in 2004, up 6 percent 
over 2003.

APPLICATION OF CRITICAL ACCOUNTING POLICIES  
AND ESTIMATES

In preparing the Company’s financial statements using gener-
ally accepted accounting principles in the United States of America 
(GAAP), management exercises judgment in the selection and ap-
plication of accounting principles, including making estimates and 
assumptions that affect reported amounts of assets, liabilities, rev-
enues, expenses and related disclosures in the financial statements. 
Management considers its critical accounting policies to be those 
which are most important to the representation of the Company’s 

financial  condition  and  results  of  operations  and  which  require 
management’s most difficult and subjective or complex judgments, 
including accounting estimates that could result in materially dif-
ferent amounts if the Company reported under different conditions 
or using different assumptions.
  The  Company’s  most  critical  estimates  or  judgments  involve 
regulatory cost recovery, unbilled revenues, derivative instruments, 
pension assumptions, income taxes and environmental contingen-
cies. Management has discussed the estimates and judgments used 
in  the  application  of  critical  accounting  policies  with  the  Audit 
Committee of the Board. The Company’s critical accounting poli-
cies and estimates are described below.
  Within the context of the Company’s critical accounting policies 
and estimates, management is not currently aware of any reason-
ably likely events or circumstances that would result in materially 
different amounts being reported.
Regulatory Accounting
  NW Natural is regulated by the Public Utility Commission of 
Oregon (OPUC) and the Washington Utilities and Transportation 
Commission (WUTC), which establish the Company’s utility rates 
and rules governing utility services provided to customers, and to 
a certain extent set forth the accounting treatment for certain regu-
latory transactions. In general, NW Natural uses the same account-
ing principles as other non-regulated companies reporting under 
GAAP. However, certain accounting principles, primarily Statement 
of Financial Accounting Standards (SFAS) No. 71, “Accounting for 
the Effects of Certain Types of Regulation,” require different ac-
counting treatment for regulated companies to show the effects of 
regulation. For example, NW Natural accounts for the cost of gas 
using a deferral and cost recovery mechanism called the Purchased 
Gas Adjustment (PGA), which is submitted for approval annually 
to the OPUC and WUTC (see “Results of Operations – Regulatory 
Matters – Rate Mechanisms,” below). There are other expenses or 
revenues that the OPUC or WUTC may require the Company to de-
fer for recovery or refund in future periods. SFAS No. 71 requires 
the Company to account for these types of deferred expenses (or 
deferred revenues) as regulatory assets (or regulatory liabilities) on 
the balance sheet. When NW Natural is allowed to recover these 
expenses from or refund them to customers, it recognizes the ex-
pense or revenue on the income statement at the same time it re-
alizes  the  adjustment  to  amounts  included  in  utility  rates  and 
charged to customers.
  The conditions a company must satisfy to adopt the accounting 
policies and practices of SFAS No. 71 applicable to regulated com-
panies include:
■  an independent regulator sets rates;
■  the regulator sets the rates to cover specific costs of delivering 
service; and
■  the service territory lacks competitive pressures to reduce rates 
below the rates set by the regulator.
  NW Natural continues to apply SFAS No. 71 in accounting for 
its regulated utility operations. Future regulatory changes or changes 
in the competitive environment could result in the Company dis-
continuing the application of SFAS No. 71 for some or all of its reg-
ulated business. This would require the write-off of those regula-
tory  assets  and  liabilities  that  would  no  longer  be  probable  of 
recovery from or refund to customers. Based on current regulatory 
and competitive conditions, NW Natural believes that it is reason-
able to expect continued application of SFAS No. 71 for its regulated 
activities, and that all of its regulatory assets and liabilities at Dec. 
31, 2004 and 2003 are recoverable or refundable through future 
customer rates.

Management’s Discussion and Analysis

Revenue Recognition
  Utility revenues, derived primarily from the sale and transporta-
tion of natural gas, are recognized when the gas is delivered to and 
received by the customer. Revenues are accrued for gas delivered 
to customers but not yet billed based on estimates of gas deliveries 
from the last meter reading date to month end (unbilled revenues). 
Unbilled revenues are primarily based on the Company’s percent-
age estimate of its unbilled gas each month, which is dependent 
upon a number of factors that require management’s judgment. 
These factors include total gas receipts and deliveries, customer 
meter  reading  dates,  customer  usage  patterns  and  weather.  Un-
billed revenue estimates are reversed the following month when 
actual billings occur. Estimated unbilled revenues at Dec. 31, 2004 
and 2003 were $64.4 million and $59.1 million, respectively. The 
increase in unbilled revenues at year-end 2004 was primarily due 
to higher gas prices included in customer rates, partially offset by 
lower unbilled volumes reflecting warmer weather and decreases 
in customer usage due to higher prices. If the estimated percentage 
of unbilled gas at Dec. 31, 2004 were adjusted up (or down) by 1 
percent, then the Company’s unbilled revenues, net operating rev-
enues and net income would have increased (or decreased) by an 
estimated $1.0 million, $0.5 million and $0.3 million, respectively.
In November 2003, NW Natural implemented a weather normal-
ization mechanism in Oregon that helps stabilize net operating rev-
enues by adjusting current customer billings based on temperature 
variances from average weather (see “Results of Operations – Reg-
ulatory Matters – Rate Mechanisms,” below). Weather normaliza-
tion is also included in unbilled revenues at the end of each account-
ing period using management’s judgments as discussed above.
  Non-utility revenues, derived primarily from interstate storage 
services, are recognized upon delivery of the service to customers. 
Revenues from optimization of excess storage and transportation 
capacity are recognized over the life of the contract for guaranteed 
amounts under the contract, or are recognized as they are earned 
for amounts above the guaranteed value based on estimates pro-
vided by the independent energy marketing company.
Accounting for Derivative Instruments and  
Hedging Activities

In providing gas distribution services, NW Natural enters into 
forward contracts to buy and sell natural gas. These contracts qual-
ify as normal purchases and normal sales under SFAS No. 133, “Ac-
counting for Derivative Instruments and Hedging Activities,” be-
cause they provide for a purchase or sale, and subsequent delivery, 
of natural gas in quantities that are probable of delivery over a rea-
sonable period of time in the normal course of business (see Note 
1, “Derivatives Policy”). Accordingly, these contracts are accounted 
for at the time of settlement and are not reflected on the Company’s 
balance sheet or income statement prior to settlement.
  The Company has an established Derivatives Policy that sets 
forth the guidelines for using selected financial derivative products 
to support prudent risk management strategies within designated 
parameters (see Note 1). The policy specifically prohibits the use 
of derivatives for trading or speculative purposes. Hedging activi-
ties consist of natural gas commodity price and foreign currency 
exchange rate hedges which are accounted for as cash flow hedges. 
These contracts that qualify as derivative instruments are recorded 
on the balance sheet at fair value. Generally, most of these con-
tracts are subject to regulatory deferral mechanisms, and as such 
any change in the fair value of these contracts is recorded as regu-
latory assets or regulatory liabilities pursuant to SFAS No. 71 (see 
Note 1, “Derivatives Policy”). The Company’s estimate of fair value 
is determined from period to period based on prices available from 
external sources and internal modeling based on index prices that 

20

are subject to market volatility. For estimated fair values at Dec. 31, 
2004 and 2003, see Note 11.
  The following table summarizes the realized gains and losses 
from commodity price and currency hedge transactions in the years 
ended Dec. 31, 2004, 2003 and 2002:

  Realized gains (losses) from commodity price and foreign cur-
rency hedge contracts are recorded as reductions (increases) to the 
cost of gas and are included in the calculation of annual PGA rate 
changes. Unrealized gains and losses resulting from mark-to-mar-
ket valuations are not recognized in current income or other com-
prehensive  income,  but  are  recorded  as  regulatory  liabilities  or 
regulatory assets, which are offset by a corresponding balance in 
non-trading derivative assets or liabilities (see Note 11).
Accounting for Pensions
  The Company has two qualified, non-contributory defined ben-
efit pension plans covering all regular employees with more than 
one year of service. These plans are funded through a trust dedi-
cated to providing retiree pension benefits. The Company also has 
several non-qualified supplemental pension plans for eligible ex-
ecutive  officers  and  certain  key  employees.  These  non-qualified 
plans are unfunded.
  Net periodic pension cost (NPPC) and accumulated benefit ob-
ligations (ABO) are determined in accordance with SFAS No. 87, 
“Employers’ Accounting for Pensions,” using a number of key as-
sumptions including the discount rate, the rate of compensation 
increases, retirement ages, mortality rates and the expected long-
term return on plan assets (see “Financial Condition – Pension Cost 
(Income) and Funding Status,” below, and Note 7). These key as-
sumptions  have  a  significant  impact  on  the  amounts  reported. 
NPPC consists of service costs, interest costs, the amortization of 
actuarial gains and losses, expected returns on plan assets and, in 
part, on a market-related valuation of assets. The market-related 
valuation reflects differences between expected returns and actual 
investment returns, which are recognized over a three-year period 
from the year in which they occur, thereby reducing year-to-year 
NPPC volatility.
  A  number  of  factors  are  considered  in  developing  pension  
assumptions, including an evaluation of relevant discount rates, 
expected long-term returns on plan assets, plan asset allocations, 
expected  changes  in  wages  and  retirement  benefits,  analyses  of 
current market conditions and input from actuaries and other con-
sultants. For the Dec. 31, 2004 measurement date, the Company:
■  decreased the discount rate assumption from 6.25 percent to 
6.00 percent;
■  maintained the rate of compensation increase in a range of 
4.00-5.00 percent; and
■  maintained the expected long-term return on plan assets at 
8.25 percent.
  The change in discount rate was the primary factor contribut-
ing to the increase in the plans’ ABO from $205 million at Dec. 31, 
2003 to $223 million at Dec. 31, 2004.
  The Company believes its pension assumptions to be appropri-
ate based on plan design and an assessment of market conditions.

  The impact of a change in NPPC on operating results would be 
less than the amounts shown above because about 60 percent of 
NPPC is charged to operations and maintenance expense. The re-
maining 40 percent is capitalized as construction overhead and in-
cluded in utility plant, which is amortized to expense over the use-
ful life of the asset placed into service.
Accounting for Income Taxes

Income taxes are accounted for in accordance with SFAS No. 
109, “Accounting for Income Taxes,” by recognizing deferred in-
come taxes for all temporary differences between the book and tax 
basis of assets and liabilities at current income tax rates.
  SFAS No. 109 also requires the recognition of additional deferred 
income tax assets and liabilities for temporary differences where 
regulators flow-through deferred income tax benefits or expenses 
in the ratemaking process of the regulated utility (regulatory tax 
assets and liabilities). This is consistent with ratemaking policies 
of the OPUC and WUTC. Regulatory tax assets and liabilities are 
recorded to the extent the Company believes they will be recover-
able from or refunded to customers in future rates. At Dec. 31, 2004 
and 2003, the Company had regulatory assets representing differ-
ences between book and tax basis related to pre-1981 property of 
$64.7 million and $63.4 million, respectively, and has recorded an 
offsetting deferred tax liability for the same amounts (see Note 1). 
NW  Natural  believes  that  it  is  reasonable  to  expect  recovery  of 
these regulatory assets through future customer rates. However, 
future regulatory changes could require the write-off of all or a por-
tion of these regulatory assets should they no longer be probable 
of recovery in future rates.
Contingencies
  Loss contingencies are recorded as liabilities when it is probable 
that a liability has been incurred and the amount of the loss is rea-
sonably estimable in accordance with SFAS No. 5, “Accounting for 
Contingencies.” Estimating probable losses requires an analysis of 
uncertainties that often depend upon judgments about potential 
actions by third parties. In the normal course of business, accruals 
are recorded for loss contingencies based on an analysis of poten-
tial results, developed in consultation with outside counsel when 
appropriate, including allowances for uncollectible accounts, envi-
ronmental claims and property damage and personal injury claims. 
Where information is sufficient to estimate only a range of prob-
able liability, and no point within the range is more likely than any 
other, the Company recognizes an accrued liability at the lower end 
of the range. It is possible, however, that future results of opera-
tions could be materially affected by changes in assumptions or 
estimates regarding these contingencies. With respect to environ-
mental claims and related litigation costs, receivables are recorded 
for  anticipated  recoveries  under  insurance  contracts  based  on 
amounts the Company estimates are probable of recovery. If these 
amounts are not recovered from insurance, the Company believes 
that recovery is probable from future utility rates based on current 
approval by the OPUC to defer these costs as a regulatory asset. 
See Note 12.

RESULTS OF OPERATIONS
Regulatory Matters
  NW Natural provides gas utility service in Oregon and Wash-
ington, with Oregon representing over 90 percent of its revenues. 
Future earnings and cash flows from utility operations will be de-

termined largely by the pace of continued growth in the residential 
and commercial markets and by NW Natural’s ability to remain 
price  competitive  in  the  large  industrial  market,  to  control  ex-
penses, and to obtain reasonable and timely regulatory ratemaking 
treatment for its operating and maintenance costs and investments 
made in utility plant.
General Rate Cases
  NW  Natural’s  most  recent  general  rate  increase  in  Oregon, 
which  was  effective  Sept. 1,  2003,  authorized  rates  designed  to 
produce a return on shareholders’ equity (ROE) of 10.2 percent. 
The OPUC approved a revenue increase of $13.9 million per year, 
of which $6.2 million went into effect on Sept. 1, 2003, and $2.7 
million went into effect on a deferred basis on Nov. 12, 2003 as the 
first 11.7 miles of the Company’s southern portion of SMPE went 
into service. The remaining $3.8 million for the southern portion 
of the SMPE went into effect on Oct. 1, 2004, upon the completion 
and placement into service of the last segment of the SMPE proj-
ect. Recovery for the Company’s Coos County distribution system 
project of $1.2 million went into effect on Nov. 1, 2004, on a de-
ferred basis. While not included in the rate case result, an addi-
tional  annual  rate  recovery  of  $7.5  million  associated  with  the 
northern portion of SMPE became effective Oct. 1, 2004.

In  November  2003,  NW  Natural  filed  a  general  rate  case  in 
Washington that proposed a revenue increase of $7.9 million per 
year from Washington operations through rate increases averag-
ing 15 percent. In June 2004, the WUTC approved a settlement 
agreement entered into by the parties to NW Natural’s Washing-
ton general rate case, which became effective on July 1, 2004, au-
thorizing a revenue increase of $3.5 million per year, or 6.5 per-
cent. In addition, the settlement authorized NW Natural to include 
the SMPE cost of service of approximately $0.7 million per year 
in rates, subject to audit, concurrent with the annual Washington 
PGA filing, which became effective on Nov. 1, 2004. See “Rate 
Mechanisms,” below.
  Notwithstanding  authorized  revenue  levels  approved  by  the 
OPUC or the WUTC, actual revenues are dependent on weather, 
economic conditions, customer growth, competition and other fac-
tors affecting gas usage in NW Natural’s service area.

In January 2005, the Company filed a rate case with the Federal 
Energy  Regulatory  Commission  (FERC)  proposing  an  update  of 
maximum rates for the Company’s interstate storage services op-
eration and new service offerings. The requested new rates are de-
signed to reflect the costs related to the further development of the 
Mist gas storage facilities and costs associated with the SMPE proj-
ect. This filing was made to satisfy FERC’s requirement that there 
be a cost and revenue review in three years following its original 
storage service rate authorization.
Rate Mechanisms
  WEATHER NORMALIZATION. In November 2003, NW Natural im-
plemented  a  weather  normalization  mechanism  in  Oregon  that 
helps stabilize net operating revenues, or margin, by adjusting cur-
rent customer billings based on temperature variances from aver-
age weather. The weather normalization mechanism approved by 
the OPUC is applied to Oregon residential and commercial custom-
ers’ bills between Nov. 15 and May 15 of each heating season. The 
mechanism adjusts the margin component of customers’ rates to 
reflect “normal” weather using the 25-year average temperature 
for each day of the billing period. The mechanism is intended to 
stabilize fixed costs and to reduce fluctuations in customers’ bills 
due to colder- or warmer-than-average weather. In October 2004, 
the mechanism was modified to limit the upward or downward 
adjustments to individual bills to certain specified ranges, with any 
excess amounts being deferred (see “Residential and Commercial 
Sales,” below).

Management’s Discussion and Analysis

PURCHASED  GAS  ADJUSTMENT.  Rate  changes  are  applied  each 
year under the PGA mechanisms in NW Natural’s tariffs in Oregon 
and Washington to reflect changes in the costs of natural gas com-
modity purchased under contracts with gas producers (see “Com-
parison of Gas Operations – Cost of Gas Sold,” below), the appli-
cation  of  temporary  rate  adjustments  to  amortize  balances  in 
regulatory asset or liability accounts and the removal of temporary 
rate adjustments effective the previous year. Pursuant to the PGA 
tariffs, in September 2004, the OPUC approved rate increases ef-
fective Oct. 1, 2004 averaging 20.1 percent for Oregon residential 
sales customers, and in October 2004, the WUTC approved rate in-
creases effective Nov. 1, 2004 averaging 19.5 percent for Washing-
ton residential sales customers. These rate increases include de-
ferred revenue from the costs related to the SMPE project, which 
was  completed  and  placed  into  service  on  Sept.  22,  2004.  The 
Oregon increase of 20.1 percent consisted of recovery of gas costs 
(13.9 percent), temporary rate adjustments (2.5 percent, including 
deferrals for SMPE) and the recovery of SMPE costs of service (3.7 
percent). The Washington increase of 19.5 percent consisted of the 
recovery of gas costs (12.0 percent), temporary rate adjustments 
(6.3 percent), and the recovery of SMPE costs (1.2 percent). The 
inclusion of SMPE costs in Oregon and Washington rates resulted 
in additional revenue increases totaling $14.7 million per year. Dur-
ing the fourth quarter of 2004, the staff of the OPUC initiated a re-
view of gas purchasing strategies for all three local gas distribution 
companies serving Oregon. The schedule, scope and potential find-
ings, including the matter of whether the review will lead to formal 
proceedings before the OPUC, remain uncertain.

In 2003, the OPUC approved a PGA rate increase averaging 3.5 
percent for Oregon sales customers and the WUTC approved a PGA 
rate increase averaging 16.8 percent for Washington sales custom-
ers, both effective on Oct. 1, 2003. In 2002, the OPUC approved PGA 
rate decreases averaging 14 percent for Oregon sales customers and 
the WUTC approved PGA rate decreases averaging 25 percent for 
Washington sales customers, both effective on Oct. 1, 2002.
  The OPUC has formalized a process that tests for excessive earn-
ings in connection with gas utilities’ annual filings under their PGA 
mechanisms.  The  OPUC  has  confirmed  NW  Natural’s  ability  to 
pass through 100 percent of its prudently incurred gas costs into 
rates. Under this requirement, NW Natural is authorized to retain 
all of its earnings up to a threshold level equal to its authorized 
ROE plus 300 basis points. One-third of any earnings above that 
level will be refunded to customers. The excess earnings threshold 
is subject to adjustment up or down each year depending on move-
ments in interest rates. No amounts were identified in this process 
for refund to customers with respect to 2003 or 2002 earnings re-
sults. NW Natural does not expect that amounts will be identified 
for refund with respect to its earnings in 2004, which will be re-
viewed by the OPUC in the second quarter of 2005.

CONSERVATION TARIFF. Effective Oct. 1, 2002, the OPUC autho-
rized NW Natural to implement a “conservation tariff,” a mecha-
nism designed to recover lost margin due to changes in residential 
and commercial customers’ consumption patterns. The tariff is a 
partial  decoupling  mechanism  that  breaks  the  link  between  the 
Company’s earnings and the quantity of energy consumed by its 
customers, so the Company does not have an incentive to discour-
age customers’ conservation efforts.
  The conservation tariff includes two components. The first, a 
price  elasticity  factor,  adjusts  for  increases  or  decreases  in  con-
sumption attributable to annual changes in commodity costs or 
periodic changes in the Company’s general rates. The second is a 
conservation adjustment calculated on a monthly basis to account 
for deviations between actual and expected volumes. Additional

revenues or credits to customers produced by the conservation ad-
justment are booked to a deferral account that is reconciled as part 
of the Company’s annual PGA. Baseline consumption is based on 
customer consumption patterns as determined in the 2003 Oregon 
general  rate  case,  adjusted  for  consumption  resulting  from  new 
customers. The partial decoupling mechanism will expire at the 
end of September 2005 unless the OPUC approves an extension 
based on the results of an independent study to measure the mech-
anism’s effectiveness. Work on the independent review, which in-
volves interested parties, is in process and is expected to be com-
pleted by the end of March 2005. The study is expected to provide 
the basis for the Company’s filing to renew the tariff.

PIPELINE INTEGRITY COST RECOVERY. In July 2004, the OPUC ap-
proved applications by NW Natural relating to the accounting treat-
ment and full recovery for the Company’s cost of its pipeline integ-
rity  management  program  (IMP)  as  mandated  by  the  Pipeline 
Safety Improvement Act of 2002 (Pipeline Safety Act) and related 
rules adopted by the U.S. Department of Transportation’s Office of 
Pipeline Safety (see “Financial Condition – Cash Flows – Investing 
Activities,” below). Under the applications as approved, NW Nat-
ural classifies its IMP costs as either capital expenditures or regu-
latory  assets,  accumulates  the  costs  over  each  12-month  period 
ending June 30, and recovers the costs, subject to audit, through 
rate changes effective on October 1 of each year commencing Oct. 
1,  2004.  The  approved  accounting  and  rate  treatment  for  these 
costs extends through Sept. 30, 2008, and may be reviewed for po-
tential extension after that date. NW Natural will begin including 
IMP costs in rates in 2005.
  OPEN PATHWAY TARIFF. The open pathway tariff, approved by the 
OPUC on Dec. 7, 2004, requires developers to provide the Company 
with a trench for installation of mains and services in new devel-
opments. If a trench is not provided, the tariff requires the devel-
oper to pay NW Natural’s costs of trenching. In the past, provision 
of a trench or reimbursement was not required. Implementation of 
the tariff began in early 2005.
OPUC Investigation

In August 2004, the OPUC approved a stipulation among NW 
Natural, the OPUC staff and two parties in the 2003 Oregon general 
rate case, providing for the settlement of issues raised in an inves-
tigation initiated by the OPUC in 2003. These issues relate to trans-
actions or interests in certain properties involving NW Natural in 
the vicinity of its headquarters building in downtown Portland, and 
the use of some of these properties for employee parking. The pri-
mary effect of the stipulation was to reverse cost recovery as of 
Sept. 1, 2003, for certain properties that should not have been in-
cluded in rate base in the 2003 Oregon general rate case, and for 
certain employee parking costs. Pursuant to the stipulation, NW 
Natural commenced paying refunds in the amount of $1.3 million 
to Oregon customers on Oct. 1, 2004, in connection with the an-
nual Oregon PGA filing effective on that date. Approximately $0.3 
million of that amount was charged to a reserve in 2003 and the 
first quarter of 2004; approximately $0.9 million was recognized as 
a reduction in other revenues in the second quarter of 2004; and 
the balance of $0.1 million was recognized as a reduction in other 
revenues in the third quarter of 2004. Effective Oct. 1, 2004, Oregon 
revenues were reduced by about $0.3 million per year to eliminate 
these costs from future rates. NW Natural agreed in the stipulation 
to undergo an audit in 2005 funded by the Company, which is ex-
pected to focus on ratemaking issues relating to the inclusion of 
assets in rate base and NW Natural’s transactions with any affili-
ated interests. The OPUC staff informed the Company that the re-
quired audit will be performed during the third quarter of 2005.

  NW Natural continued to grow its customer base, with a net in-
crease of 18,485 customers during 2004. The growth rate for both 
2004 and 2003 was 3.2 percent, compared to 3.5 percent in 2002. 
In the three years ended Dec. 31, 2004, more than 55,000 custom-
ers  were  added  to  the  system,  representing  an  average  annual 
growth rate of 3.4 percent.

2004 compared to 2003:
■  volumes sold were 1 percent lower, reflecting the effect of 3 
percent warmer weather that was partially offset by the impact 
of 3 percent customer growth; and
■  operating revenues were 13 percent higher, primarily due to 
higher rates effective Oct. 1, 2003 and Oct. 1, 2004 (see “Regula-
tory Matters – Rate Mechanisms,” above).
2003 compared to 2002:
■  volumes sold were 1 percent lower, reflecting the effects of 7 
percent warmer weather that was partially offset by the impact 
of 3 percent customer growth and the price elasticity effect of 
lower rates effective Oct. 1, 2002; and

■  operating revenues were 4 percent lower in 2003 than in 2002. 
Excluding the impact of gas cost refunds totaling $30.4 million 
during 2002, revenues were $54.6 million, or 10 percent, lower  
in 2003 than in 2002, primarily due to lower rates effective  
Oct. 1, 2002.
  Typically, 80 percent or more of annual utility operating reve-
nues are derived from gas sales to weather-sensitive residential and 
commercial  customers.  Although  variations  in  temperatures  be-
tween periods will affect volumes of gas sold to these customers, 
the effect on margin and net income was significantly reduced with 
the implementation of the weather normalization mechanism in 
Oregon beginning in November 2003 (see “Regulatory Matters – 
Rate Mechanisms,” above). This mechanism applies to meter read-
ings of participating Oregon customers taken between Nov. 15 and 
May 15. Approximately 10 percent of NW Natural’s residential and 
commercial customers are in Washington, where the mechanism 
is not in effect, and about 8 percent of the eligible Oregon custom-
ers elected not to be covered by the mechanism, so the mechanism 
does not fully insulate the Company from utility earnings volatility 
due to weather. The mechanism contributed a net $9.0 million of 
margin, equivalent to 20 cents a share of earnings, in the twelve 
month period ended Dec. 31, 2004, making up a significant portion 
of the margin that otherwise would have been lost from warmer-
than-average weather. In 2003, the mechanism contributed $1.9 
million of margin, equivalent to 5 cents a share of earnings, in the 
two-months after becoming effective in November 2003.
  Total utility operating revenues include accruals for gas deliv-
ered but not yet billed to customers (unbilled revenues) based on 
estimates of gas deliveries from that month’s meter reading dates 
to month end. Amounts reported as unbilled revenues reflect the 
increase or decrease in the balance of accrued unbilled revenues 
compared to the prior year-end. Weather conditions, rate changes 
and customer billing dates affect the balance of accrued unbilled 
revenue at the end of each month. At Dec. 31, 2004, accrued un-
billed revenue was $64.4 million, compared to $59.1 million at Dec. 
31, 2003.

  Total  volumes  delivered  to  industrial  and  electric  generation 
customers were 39 million therms, or 7 percent, higher in 2004 
than in 2003, and utility operating revenues were up $37 million, 
or 50 percent. The higher volumes and revenues partially reflect 
an improving economy, but results primarily reflect a continued 
shift from transportation to sales volumes and the reclassification 
of a relatively large number of commercial customers to the indus-
trial customer category over the past 24 months resulting from new

rate design changes in Oregon. Over the past two years, the num-
ber of industrial customers increased 30 percent from 2002 to 2003, 
and 24 percent from 2003 to 2004. Industrial rates in Oregon were 
redesigned as part of the general rate case in 2003, transferring $4.8 
million of annual revenue requirement from industrial rates to res-
idential and commercial rates in order to better reflect relative costs 
of service and to improve the competitiveness of the Company’s 
rates in the industrial market.
  Total volumes delivered to industrial and electric generation cus-
tomers were 18 million therms, or 3 percent, lower in 2003 than in 
2002, and utility operating revenues were down $10 million, or 11 
percent. Results from the industrial market in 2003 reflect weaker 
economic conditions during the year, and most of the incremental 
revenue decline was due to a shift from higher margin firm sched-
ules to lower margin interruptible schedules and industrial rate de-
creases effective in September 2003.
  The decline in volumes and operating revenues from the elec-
tric  generation  market  primarily  reflect  the  winding  down  of  a 
temporary market that emerged in response to the 2001-2002 en-
ergy crisis. The volumes and operating revenues in 2002 were re-
lated to two customers served under contracts that went into effect 
in the second half of 2001 and expired at the end of the second 
quarter of 2002. Most of the revenues from these contracts were 
derived from fixed charges. A third electric generation customer 
used 3.0 million therms in 2002 under a contract with low volu-
metric charges.
Other Revenues
  Other  revenues  include  miscellaneous  fee  income  as  well  as 
revenue adjustments reflecting deferrals to, or amortizations from, 
regulatory asset or liability accounts other than deferrals relating 
to gas costs (see Note 1). Other revenues increased net operating 
revenues by $3.2 million in 2004, compared to $7.5 million in 2003 
and $4.0 million in 2002. The following table summarizes other

  Other revenues in 2004 were $4.3 million lower than in 2003 
primarily due to the change in decoupling deferrals under the de-
coupling mechanism (down $2.8 million) (see “Regulatory Mat-
ters – Rate Mechanisms,” above), the amortization of decoupling 
deferrals from prior periods (up $2.2 million) and an increase in 
other miscellaneous amortizations (up $1.6 million), partially off-
set by higher interstate storage credits from revenue sharing from 
the Company’s interstate gas storage services (up $2.3 million).
  Other revenues in 2003 included positive contributions due to 
the change in decoupling deferrals (up $1.7 million), the amortiza-

tion of income shared with customers from interstate gas storage 
services (up $1.8 million), and customer late payment and collec-
tion fees and miscellaneous revenues, partially offset by amortiza-
tions from regulatory accounts covering conservation programs and 
Year 2000 technology costs.
Cost of Gas Sold
  Natural gas commodity prices have fluctuated significantly in 
recent years. The effects of higher gas commodity prices and price 
volatility on core utility customers are mitigated through the use 
of  underground  storage  facilities,  gas  commodity-price  financial 
hedge contracts, and short-term sales of gas commodity and trans-
portation capacity to on-system or off-system customers in periods 
when core utility customers do not require the full firm pipeline 
capacity and gas supplies.
  The Company regularly renews or replaces its expiring long-
term and medium-term contracts with new agreements with a va-
riety of existing and new suppliers. No single contract amounts to 
more than 200,000 therms per day or 10 percent of the Company’s 
average daily contract volumes. Firm year-round supply contracts 
have terms ranging from one to ten years. All of the contracts use 
price formulas tied to monthly index prices, primarily at the NOVA 
Inventory Transfer trading point in Alberta. NW Natural hedges a 
majority of its contracts each year using financial instruments as 
part of its gas purchase strategy.
  The total cost of gas sold was $399.2 million in 2004, an in-
crease of $76.1 million or 24 percent compared to 2003 and, 2003 
was $29.9 million or 8 percent lower than 2002. The cost per therm 
of gas sold was 14 percent higher in 2004 than in 2003 and 9 per-
cent lower in 2003 than in 2002. The cost per therm of gas sold in-
cludes current gas purchases, gas drawn from storage inventory, 
gains or losses from commodity hedges, margin from off-system 
gas sales, demand cost balancing adjustments (demand equaliza-
tion), regulatory deferrals and company use. Results for 2002 in-
cluded an adjustment that reduced cost of gas by $29.5 million, a 
result of a refund to customers. Excluding this adjustment, cost per 
therm of gas sold was 16 percent lower in 2003 than in 2002, re-
flecting decreases in gas commodity prices effective in late 2002.
  Results for 2002 also included adjustments reducing cost of gas 
relating to amounts of deferred expenses for the recovery of pipe-
line  demand  charges  under  the  PGA  mechanism.  These  adjust-
ments contributed 7 cents a share to earnings in 2002, of which 6 
cents a share applied to periods prior to 2002. The rate methodol-
ogy represented in the adjustments continues to be applied in the 
Company’s accounting for pipeline demand charges.
  NW Natural’s recorded amount of unaccounted-for gas was 0.51 
percent of gas sendout in 2004, compared to 0.55 percent in 2003 
and 0.75 percent in 2002. Unaccounted-for gas is the difference be-
tween the amount of gas the Company receives from all sources, 
including pipeline deliveries and withdrawals from storage, and 
the amount of gas it delivers to customers or other delivery points. 
Unaccounted-for gas may be caused in part by physical gas leak-
age, but it also may be due to cumulative inaccuracies in gas me-
tering, estimates of unbilled gas or other causes. A normal amount 
of unaccounted-for gas is considered to be 0.50 percent of total gas 
sendout during a period, but the amounts may vary within a range 
around this estimate. During 2004, the lower estimated amount of 
unaccounted-for gas had the effect of increasing cost of gas and 
decreasing margin by $0.4 million as compared to 2003. During 
2003, the lower estimated amount of unaccounted-for gas had the 
effect of reducing cost of gas and increasing margin by $1.2 million 
as compared to 2002. The estimated percentages of unaccounted-
for gas in 2004 and 2003 were lower than 2002, partially due to 
improvements in gas measurement and estimating.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     
 
 
 
     
 
 
 
 
 
 
     
 
 
 
     
     
     
  NW Natural uses a natural gas commodity-price hedge program 
under the terms of its Derivatives Policy to help manage its vari-
able price gas commodity contracts (see “Application of Critical 
Accounting Policies and Estimates – Accounting for Derivative In-
struments and Hedging Activities,” above). NW Natural recorded 
net hedging gains of $42.4 million from this program during 2004, 
compared to net hedging gains of $32.4 million in 2003 and net 
hedging losses of $75.5 million in 2002. Hedging gains and losses 
relating to gas commodity purchases are included in cost of gas 
and  factored  into  NW  Natural’s  annual  PGA  rate  changes,  and 
therefore have no material impact on net income.
  Under NW Natural’s PGA tariff in Oregon, net income is affected 
within defined limits by changes in purchased gas costs. NW Nat-
ural is allowed to collect an amount for purchased gas costs based 
on estimates that are included in current utility rates. If the actual 
purchased gas costs are higher than the amounts included in rates, 
NW Natural is not allowed to charge its customers currently for 
those higher gas costs but is allowed to defer the costs and collect 
them in the future. Similarly, when the actual purchased gas costs 
are lower than the amount included in rates, the savings are not 
immediately passed on to customers but are deferred and refunded 
in future periods. NW Natural absorbs 33 percent of the higher cost 
of gas sold, or retains 33 percent of the lower cost, in either case 
as compared to the projected costs built into rates. The remaining 
67 percent of the higher or lower gas costs is recorded as deferred 
regulatory assets or liabilities for recovery from or refund to cus-
tomers in future rates. In 2004 and 2003, NW Natural’s gas costs 
were slightly lower than the gas costs embedded in rates, with the 
effect that NW Natural’s share of the lower costs increased margin 
by $0.6 million and $0.3 million, equivalent to 1 cent a share and 
less than 1 cent a share of earnings, respectively. In 2002, NW Nat-
ural’s gas costs were much lower than the projected costs built into 
rates and the Company’s share of the savings realized from gas 
purchases contributed $10.8 million of margin, equivalent to 26 
cents a share of earnings.
  NW Natural uses gas supplies and transportation capacity that 
are not required for core utility residential, commercial and indus-
trial firm customers to make off-system sales. Under the PGA tariff 
in Oregon, NW Natural retains 33 percent of the margins realized 
from its off-system gas sales and records the remaining 67 percent 
as a deferred regulatory asset or liability for recovery from or re-
fund to customers in future rates. NW Natural’s share of margin 
from off-system gas sales in 2004 resulted in a loss of $0.3 million, 
equivalent to less than 1 cent a share. NW Natural’s share of mar-
gin from off-system gas sales in 2003 was $4.9 million, equivalent 
to 11 cents a share of earnings. Results for 2003 reflected a higher 
volume of off-system gas sales because of warmer weather in the 
first quarter and higher gas prices. NW Natural was able to use gas 
supplies that were available under contract for the winter season, 
but not required for delivery to core utility market customers, to 
make these off-system sales. NW Natural’s purchase price for this 
gas had been fixed through commodity swap and call option con-
tracts entered into earlier at levels substantially below the market 
prices in 2003. NW Natural’s share of margin from off-system sales 
in 2002 was $0.9 million or 2 cents a share.
Business Segments Other than Local Gas Distribution
Interstate Gas Storage
  NW Natural earned net income from its non-utility interstate gas 
storage business segment in 2004, after regulatory sharing and in-
come taxes, of $2.9 million or 11 cents a share, compared to $4.3 
million or 17 cents a share in 2003 and $3.6 million or 14 cents a 
share in 2002 (see Note 2). Earnings from this business segment 
were lower in 2004 primarily due to a lower contribution from a 
contract with an independent energy marketing company that op-

timizes the value of NW Natural’s assets by engaging in trading ac-
tivities using temporarily unused portions of its upstream pipeline 
transportation capacity and gas storage capacity. The lower contri-
bution was primarily due to a change in market conditions in which 
gas price differentials were less volatile in 2004 compared to 2003.
In Oregon, NW Natural retains 80 percent of the pre-tax income 
from the interstate storage services and optimization of storage and 
pipeline transportation capacity when the costs of such capacity 
have not been included in core utility rates, and 33 percent of the 
pre-tax income from such optimization when the capacity costs 
have been included in core utility rates. The remaining 20 percent 
and 67 percent, respectively, are credited to a deferred regulatory 
account for distribution to NW Natural’s core utility customers. 
NW Natural has a similar sharing mechanism in Washington for 
revenue derived from third party optimization services.
Subsidiaries
Financial Corporation
  Financial Corporation’s operating results in 2004 were net in-
come of $0.2 million, compared to $0.7 million in 2003 and $1.2 
million in 2002. The decrease in net income in 2004 compared to 
2003 was primarily due to a $0.5 million write-down of its limited 
partnership interests in three solar electric generation projects. The 
write-down related to an agreement to sell these projects on Jan. 
31, 2005. The decrease in net income in 2003 compared to 2002 
was due to lower income from investments in limited partnerships 
in wind and solar electric generation projects in California.
  The Company’s investment in Financial Corporation was $5.7 
million at Dec. 31, 2004, compared to $5.5 million at Dec. 31, 2003.
Northwest Energy
  Northwest Energy was formed in 2001 to serve as the holding 
company for NW Natural and PGE if the acquisition of PGE had 
been completed. Northwest Energy recorded nominal expenses for 
corporate development activities in 2004. Upon the termination of 
the proposed acquisition effort in 2002, Northwest Energy recorded 
a loss totaling $8.4 million (after tax) for the transaction costs in-
curred in connection with this effort. These charges were equiva-
lent to 33 cents a share. Northwest Energy was inactive during both 
2004 and 2003.
Operating Expenses
Operations and Maintenance
  Operations and maintenance expenses increased $5.7 million, 
or 6 percent, in 2004 compared to 2003, and increased $11.3 mil-
lion, or 13 percent, in 2003 compared to 2002. The following sum-
marizes the major factors that contributed to changes in operations 
and maintenance expense:
2004 compared to 2003
■  payroll and payroll-related expenses, including pension and 
health care costs, increased by $3.5 million due to salary and 
wage increases averaging 3 to 4 percent; and a change in the 
pension discount rate assumption and rising health care premi-
ums (see Note 7);
■  expenses for compliance activities relating to the Sarbanes- 
Oxley Act of 2002 increased by $1.5 million;
■  uncollectible accounts expense increased by $1.3 million due 
to increases in gross revenues stemming from higher rates;
■  gas technology research costs increased by $0.3 million;
■  workers compensation expense decreased by $0.4 million; and
■  energy efficiency rebate costs decreased by $0.8 million.
2003 compared to 2002
■  payroll and payroll-related expenses including pension and 
health care costs, increased by $8.9 million due to salary, wage 
and bonus increases, increased vacation accruals and increased 
pension costs due to a change in the pension discount rate as-
sumption and pension fund losses in 2001 and 2002 (see Note 7);

Management’s Discussion and Analysis

■  business risk insurance and workers compensation insurance 
premiums increased by $1.2 million;
■  professional service fees and contract labor increased by  
$1.2 million;
■  workers compensation claims expense increased by $0.5 mil-
lion primarily due to a single claim incurred in 2003;
■  other operating costs increased $0.4 million; and
■  uncollectible accounts expense decreased by $0.9 million due 
to improvements in collection rates and lower net write-offs of 
accounts receivable.
  Most of the cost increases NW Natural experienced in 2004 and 
2003 were included in the rate increases approved in the Compa-
ny’s general rate cases in Oregon and Washington (see “Regulatory 
Matters – General Rate Cases,” above).
Taxes Other Than Income Taxes
  Taxes other than income taxes, which are principally comprised 
of property, franchise and payroll taxes, increased $3.7 million, or 
11 percent, in 2004 compared to 2003, and increased $1.0 million, 
or 3 percent, in 2003 compared to 2002. The following table sum-
marizes the changes in taxes other than income taxes:

  The increase in franchise taxes in 2004 is primarily related to the 
increase in total utility operating revenues resulting from higher 
gas rates (see “Comparison of Gas Distribution Operations,” above); 
the increase in payroll taxes is primarily related to the increase in 
payroll expense (see “Operations and Maintenance,” above); and 
the increase in property taxes is primarily related to increased util-
ity plant in service (see Note 9).

  The Company’s total depreciation and amortization expense in-
creased by $3.1 million, or 6 percent, in 2004 and by $2.2 million, 
or 4 percent, in 2003. The increased expense for both years is pri-
marily due to additional investments in utility property that were 
made to meet continuing customer growth, including the Compa-
ny’s investment in the SMPE that was put into service in Novem-
ber  2003  and  September  2004  (see  “Financial  Condition –  Cash 

26

N W   N AT U R A L

Flows – Investing Activities,” below).
Other Income (Expense)
  Other income (expense) improved by $0.7 million in 2004. The 
increase was primarily due to reductions in interest charges on de-
ferred regulatory account balances ($1.1 million) reflecting lower 
net credit balances outstanding in these accounts. This increase 
was partially offset by a decrease in gains from Company-owned 
life insurance ($0.6 million) due to decreases in the market value 
of equity-based life insurance investments.
  Other income (expense) improved by $17.0 million in 2003, pri-
marily due to the $13.9 million pre-tax charge in 2002 for costs in-
curred in the effort to acquire PGE. Excluding this charge, other 
income (expense) increased by $3.1 million in 2003. The increase 
was  primarily  due  to  reductions  in  interest  charges  on  deferred 
regulatory  account  balances  ($1.4  million)  reflecting  lower  net 
credit balances outstanding in these accounts, and an increase in 
gains from Company-owned life insurance ($2.0 million) due to 
increases in the market value of equity-based life insurance invest-
ments, partially offset by a decrease in earnings from equity invest-
ments ($0.5 million) due to lower income from partnership invest-
ments held by Financial Corporation.
Interest Charges – Net of Amounts Capitalized

Interest charges–net of amounts capitalized in 2004 was $0.7 
million, or 2 percent, higher than in 2003. The increase in 2004 
was primarily due to higher balances of debt outstanding during 
the period. The increase was partially offset by lower average in-
terest rates and higher amounts of Allowance for Funds Used Dur-
ing Construction (AFUDC) due to higher average balances of con-
struction work in progress (CWIP). AFUDC represents the cost of 
funds used for CWIP (see Note 1). In 2004, AFUDC reduced inter-
est expense by $1.0 million compared to reductions of $0.9 million 
in 2003 and $0.6 million in 2002. The average interest rate compo-
nent of AFUDC, comprised of short-term and long-term borrowing 
rates, as appropriate, was 3.0 percent in 2004, 2.3 percent in 2003 
and 2.8 percent in 2002.

Interest charges–net of amounts capitalized in 2003 was $1.0 
million, or 3 percent, higher than in 2002, also due to higher bal-
ances of debt outstanding and to the inclusion of dividends paid 
in the second half of 2003 totaling $0.2 million on the Company’s 
redeemable preferred stock, due to their classification as interest 
expense upon the adoption of SFAS No. 150, “Accounting for Cer-
tain Financial Instruments with Characteristics of both Liabilities 
and Equity.”
Income Taxes
  The effective corporate income tax rates were 34.4 percent, 33.7 
percent and 34.9 percent for the years ended Dec. 31, 2004, 2003 
and 2002, respectively. The higher rate in 2004 reflects the effect 
of decreased tax benefits from a non-taxable gain on Company- and 
trust-owned life insurance ($0.6 million), decreased tax benefits 
attributed to tax adjustments recorded in the prior year ($0.3 mil-
lion), decreased tax benefits resulting from a taxable gain on the 
surrender of certain Company-owned life insurance ($0.1 million) 
and the expiration of a federal low-income housing tax credit ($0.1 
million), partially offset by the effect of increased tax benefits from 
an  adjustment  of  the  Company’s  deferred  income  tax  balances 
($0.5 million). Excluding the impact of these tax benefits taken into 
account during 2004, the effective tax rate for 2004 would have 
been 35.0 percent. The lower tax rate for 2003 reflects increased 
tax benefits from a non-taxable gain on Company- and trust-owned 
life insurance. Excluding these benefits, the effective tax rate for 
2003 would have been 35.0 percent. The tax rate for 2002 includes 
the effect of the tax benefits from the $13.9 million charge for PGE 
transaction costs. Excluding this charge, the effective tax rate for 
2002 would have been 35.6 percent.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     
 
 
     
 
     
 
 
 
 
     
     
     
 
 
 
 
 
 
     
     
 
 
 
     
     
     
 
 
 
     
     
     
 
 
 
 
 
 
 
 
Redeemable Preferred and Preference Stock  
Dividend Requirements
  Redeemable preferred and preference stock dividend require-
ments decreased $0.3 million in 2004 compared to 2003 due to 
the redemption in November 2003 of all outstanding shares of 
the Company’s $7.125 Series of Redeemable Preferred Stock with 
an aggregate stated value of $7.5 million at the applicable early 
redemption price of 102.375 percent. No shares of redeemable 
preferred or preference stock were outstanding at any time dur-
ing 2004.
  Redeemable preferred and preference stock dividend require-
ments decreased $2.0 million in 2003 compared to 2002 due to the 
redemption in December 2002 of all of the outstanding shares ($25 
million aggregate stated value) of the Company’s $6.95 Series of 
Redeemable Preference Stock pursuant to the mandatory redemp-
tion provisions applicable to that Series.

FINANCIAL CONDITION
Capital Structure
  The  Company’s  goal  is  to  maintain  a  target  capital  structure 
comprised of 45 to 50 percent common stock equity and 50 to 55 
percent long-term and short-term debt. When additional capital is 
required, debt or equity securities are issued depending upon both 
the target capital structure and market conditions. These sources 
also are used to meet long-term debt redemption requirements and 
short-term commercial paper maturities (see “Liquidity and Capi-
tal Resources,” below, and Notes 3 and 5). The Company’s con-
solidated capital structure at Dec. 31 was as follows:

  Achieving the target capital structure and maintaining sufficient 
liquidity are necessary to maintain attractive credit ratings and have 
access to capital markets at reasonable costs.
Liquidity and Capital Resources
  At Dec. 31, 2004, the Company had $5.2 million in cash and 
cash equivalents compared to $4.7 million at Dec. 31, 2003. Short-
term liquidity is provided by cash from operations and from the 
sale of commercial paper notes, which are supported b y commit-
ted bank lines of credit. The Company has available through Sept. 
30, 2005 committed lines of credit totaling $150 million with four 
commercial  banks  (see  “Lines  of  Credit,”  below,  and  Note  6). 
Short-term debt balances typically are reduced toward the end of 
the winter heating season as a significant amount of the Company’s 
current assets, including accounts receivable and natural gas in-
ventories, are converted into cash.
  Capital expenditures primarily relate to utility construction re-
sulting from customer growth and system improvements (see “Cash 
Flows – Investing Activities,” below). Certain contractual commit-

ments under capital leases, operating leases and gas supply pur-
chase and other contracts require an adequate source of funding. 
These capital and contractual expenditures are financed through 
cash from operations and from the issuance of short-term debt, 
which is periodically refinanced through the sale of long-term debt 
or equity securities.
  To provide long-term financing, in February 2004 the Company 
filed a universal shelf registration with the Securities and Exchange 
Commission (SEC) providing for the issuance and sale of up to 
$200 million of securities, which may consist of secured debt (First 
Mortgage  Bonds),  unsecured  debt,  preferred  stock  or  common 
stock. Concurrent with this shelf filing, the Company deregistered 
the $60 million of Medium-Term Notes (MTNs) remaining on its 
previous shelf registration. The $200 million universal shelf regis-
tration statement became effective in February 2004. In April 2004, 
the Company issued $40 million of common stock under the shelf 
registration, leaving $160 million available for the issuance of debt 
or equity securities (see “Financing Activities,” below).
  Neither NW Natural’s Mortgage and Deed of Trust nor the in-
dentures under which other long-term debt is issued contain credit 
rating triggers or stock price provisions that require the acceleration 
of debt repayment. Also, there are no rating triggers or stock price 
provisions contained in contracts or other agreements with third 
parties, except for agreements with certain counter-parties under 
NW Natural’s Derivatives Policy which require the affected party to 
provide substitute collateral such as cash, guaranty or letter of credit 
if credit ratings are lowered to non-investment grade, or in some 
cases if the mark-to-market value exceeds a certain threshold.
  Based on the availability of short-term credit facilities and the 
ability to issue long-term debt and equity securities, the Company 
believes it has sufficient liquidity to satisfy its anticipated cash re-
quirements, including the contractual obligations and investing and 
financing activities discussed below.
Dividend Policy
  NW Natural has paid quarterly dividends on its common stock 
in each year since the stock first was issued to the public in 1951. 
Annual  common  dividend  payments  have  increased  each  year 
since 1956. The amount and timing of dividends payable on the 
Company’s  common  stock  are  within  the  sole  discretion  of  the 
Company’s Board of Directors. It is the intention of the Board of 
Directors to continue to pay cash dividends on the Company’s com-
mon stock on a quarterly basis. However, future dividends will be 
dependent upon NW Natural’s earnings, its financial condition and 
other factors.
Off-Balance Sheet Arrangements
  The Company has no material off-balance sheet financing ar-
rangements.
Contractual Obligations
  The following table shows the Company’s contractual obligations 
by maturity and type of obligation. NW Natural also has obligations 
with  respect  to  its  pension  and  post-retirement  medical  benefit 
plans (see Note 7).

Management’s Discussion and Analysis

  Other  purchase  commitments  primarily  consist  of  remaining 
balances under existing purchase orders and remaining payments 
due to a general contractor for the construction of the remaining 
portion of the SMPE project. These and other contractual obligations 
are financed through cash from operations and from the issuance 
of short-term debt, which is periodically refinanced through the 
sale of long-term debt or equity securities.
  Holders of certain long-term debt have put options that, if exer-
cised, would accelerate the maturities by $10 million in 2005 and 
by $20 million in each of 2007, 2008 and 2009. The interest coupon 
rate on the long-term debt issues with put options range between 
6.52 percent and 7.05 percent.
  On March 12, 2004, NW Natural employees who are members 
of the OPEIU, Local No. 11, approved a new labor agreement (Joint 
Accord) covering wages, benefits and working conditions that will 
expire on May 31, 2009. In accordance with the terms of the Joint 
Accord, beginning Jan. 1, 2005, the Company will commence mak-
ing contributions to a multi-employer trust that will provide addi-
tional retirement benefits to its bargaining unit employees.
Commercial Paper
  The Company’s primary source of short-term funds is from the 
sale of commercial paper notes payable. In addition to issuing com-
mercial paper to meet seasonal working capital requirements, in-
cluding the financing of gas purchases and accounts receivable, 
short-term debt is also used temporarily to fund capital require-
ments. Commercial paper is periodically refinanced through the 
sale of long-term debt or equity securities. NW Natural’s outstand-
ing commercial paper, which is sold under an agency agreement 
with a commercial bank, is supported by committed bank lines of 
credit (see “Lines of Credit,” below). NW Natural had $102.5 mil-
lion in commercial paper notes outstanding at Dec. 31, 2004, com-
pared to $85.2 million outstanding at Dec. 31, 2003.
Lines of Credit
  Effective Oct. 1, 2004, NW Natural entered into lines of credit 
with Bank of America, N.A., JP Morgan Chase Bank, U.S. Bank 
National Association, and Wells Fargo Bank, totaling $150 million 
in aggregate. Half of the credit facility with each bank, or $75 mil-
lion, is committed and available through Sept. 30, 2005, and the 
other $75 million is committed and available through Sept. 30, 2007. 
Bank of America, N.A., JP Morgan Chase Bank, and U.S. Bank Na-
tional Association have each committed $20 million for each of 
their 2005 and 2007 lines of credit, and Wells Fargo Bank has com-
mitted $15 million for each of its 2005 and 2007 lines of credit.
  Under the terms of these lines of credit, NW Natural pays com-
mitment fees but is not required to maintain compensating bank 
balances. The interest rates on any outstanding borrowings under 
these lines of credit are based on current market rates. There were 
no outstanding balances on these lines of credit at Dec. 31, 2004 
or 2003.
  NW Natural’s lines of credit require that credit ratings be main-
tained in effect at all times and that notice be given of any change 
in its senior unsecured debt ratings. A change in NW Natural’s 
credit rating is not an event of default, nor is the maintenance of a 
specific minimum level of credit rating a condition to drawing upon 
the lines of credit. However, interest rates on any loans outstand-
ing under NW Natural’s bank lines are tied to credit ratings, which 
would  increase  or  decrease  the  cost  of  debt  outstanding  under 
these lines of credit, if any, when ratings are changed.
  The lines of credit require the Company to maintain an indebt-
edness  to  total  capitalization  ratio  of  65  percent  or  less  and  to 
maintain a consolidated net worth at least equal to 80 percent of 
its net worth at Sept. 30, 2004, plus 50 percent of the Company’s 

28

N W   N AT U R A L

net income for each subsequent fiscal quarter. NW Natural was in 
compliance with the covenants as of Dec. 31, 2004, with an indebt-
edness to total capitalization ratio of 52 percent and a net worth 
of $568.5 million compared to a required $452.1 million. The Com-
pany was also in compliance with these covenants under previous 
line of credit agreements in effect as of Dec. 31, 2003. Failure to 
comply with either of these covenants would entitle the banks to 
terminate their lending commitments and to accelerate the matu-
rity of all amounts outstanding.
Credit Ratings
  The table below summarizes NW Natural’s credit ratings from 
three rating agencies, Standard and Poor’s Rating Services (S&P), 
Moody’s Investor Service (Moody’s) and Fitch Ratings (Fitch).

In December 2004, NW Natural’s corporate credit rating was 
upgraded by S&P to “A+” from “A”, which also assigned NW Nat-
ural a business profile score of “1” on a scale of “1” to “10”, where 
“1” is the strongest score. Each of the rating agencies has assigned 
NW Natural an investment grade rating. These credit ratings and 
business profile scores are dependent upon a number of factors, 
both qualitative and quantitative, and are subject to change at any 
time. The disclosure of these credit ratings is not a recommenda-
tion  to  buy,  sell  or  hold  the  Company’s  securities.  Each  rating 
should be evaluated independently of any other rating.
Optional Redemptions of Long-Term Debt and  
Redeemable Preferred Stock

In 2003, the Company exercised early redemption provisions 
applicable to certain of its long-term debt, including all $4 million 
of the 7.50% Series B MTNs due 2023, all $11 million of the 7.52% 
Series B MTNs due 2023, and all $20 million of the 7.25% Series 
B MTNs due 2023. These MTNs were redeemed in the third quar-
ter of 2003 at 103.75 percent, 103.76 percent and 103.65 percent of 
their respective principal amounts. In the fourth quarter of 2003, 
the Company also exercised early redemption provisions applicable 
to all of the remaining shares of its $7.125 Series of Redeemable 
Preferred Stock with an aggregate stated value of $7.5 million, at 
a redemption price equivalent to 102.375 percent. The Company 
redeemed the MTNs and the preferred stock with available cash or 
with the proceeds from sales of commercial paper, and re-financed 
this long-term debt and preferred stock through the sale of new 
long-term debt in the fourth quarter of 2003. Early redemption pre-
miums are recognized as unamortized costs on debt redemptions 
pursuant to SFAS No. 71 and are amortized to expense over the life 
of the new debt.
Cash Flows
Operating Activities

 Year-over-year changes in the Company’s operating cash flows 
are primarily affected by net income and non-cash adjustments to 
net income. In 2004, net income and non-cash adjustments to net 
income increased by $18 million, but the cash flow increase was 
offset by increases in working capital requirements within the util-
ity segment resulting from warmer weather, higher prices of natu-
ral gas, and the timing of customer collections, payments for natu-
ral gas purchases and deferred gas cost recoveries. In 2003, net 
income and non-cash adjustments to net income decreased by $18 
million primarily due to a $13.9 million non-cash write-down of 
PGE acquisition costs.

  The overall change in cash flow from operations was negligible 
in 2004 compared to 2003, but decreased by $16 million in 2003 
compared to 2002. The significant factors contributing to the cash 
flow changes between years are as follows:
2004 compared to 2003
■  an increase in net income added $4.6 million to cash flow;
■  an increase in deferred tax expense added $23.0 million to 
cash flow, reflecting higher tax benefits from accelerated bonus 
depreciation on large capital additions that were placed into ser-
vice in 2004;
■  an increase in inventories reduced cash flow by $22.8 million, 
primarily reflecting higher volumes and higher unit prices on  
gas inventories in storage facilities (see “Results of Operations – 
Comparison of Gas Operations,” above);
■  an increase in regulatory receivables for deferred gas costs  
reduced cash flow by $10.2 million, reflecting different patterns 
of activity between the two years with respect to purchased  
gas cost savings and off-system gas sales under NW Natural’s 
PGA tariff (see “Results of Operations – Comparison of Gas  
Operations – Cost of Gas Sold,” above);
■  an increase in accounts receivable also reduced cash flows  
by $8.1 million, reflecting the impact of higher rates compared  
to the prior year (see “Results of Operations – Regulatory Mat-
ters,” above);
■  cash contributions to the Company’s non-bargaining unit de-
fined benefit pension plan lowered cash flows by $8.3 million, 
compared to no contributions in 2003 or 2002 (see “Pension  
Cost (Income) and Funding Status,” below);
■  a smaller increase in accrued unbilled revenue added $9.7  
million to cash flow, reflecting higher gas prices, partially offset 
by lower unbilled volumes because of warmer weather and  
decreases in customer usage because of higher prices;
■  an increase in other long term liabilities added $8.2 million  
to cash flow, reflecting an increase in accruals for environmental 
and other claims, as well as increases in accruals for unfunded  
liabilities for pension and post-retirement benefits;
■  an increase in income taxes receivable reduced cash flow by 
$7.3 million; and
■  a decrease in prepayments and other current assets increased 
cash flow by $3.5 million.
2003 compared to 2002
■  an increase in net income added $2.2 million to cash flow;
■  a non-cash adjustment to net income in 2002 for the loss  
recorded for PGE costs resulted in a net decrease in 2003 of  
$13.9 million;
■  a significant increase in accrued unbilled revenue reduced 
cash flow by $28.7 million, reflecting a combination of higher 
gas prices and colder weather in December 2003 compared to 
December 2002;
■  a significant increase in accounts receivable reduced cash flow 
by $22.9 million, primarily reflecting the higher gas prices and 
the timing of customer account collections;
■  a decrease in deferred gas costs payable reduced cash flow by 
$5.6 million, largely due to a significant refund to customers in 
2002 of accumulated gas cost savings;
■  a decrease in accrued interest and taxes payable added $16.4 

million to cash flow, primarily reflecting higher tax benefits from 
accelerated bonus depreciation;
■  a decrease in inventories of gas, materials and supplies added 
$15.9 million to cash flow, primarily due to lower volumes of 
natural gas in storage, partially offset by higher gas commodity 
prices;
■  a decrease in prepaid income taxes added $9.5 million to cash 
flow; and
■  an increase in accounts payable added $7.9 million to cash flow.
  The Company has lease and purchase commitments relating 
to its operating activities that are financed with cash flows from 
operations  (see  “Liquidity  and  Capital  Resources,”  above,  and 
Note 12).
  The Job Creation and Worker Assistance Act of 2002 (the As-
sistance Act) combined with the Jobs and Growth Tax Relief Rec-
onciliation Act of 2003 (the Reconciliation Act), allowed for an ad-
ditional first-year tax depreciation deduction on the adjusted basis 
of “qualified property.” The Assistance Act provided for an addi-
tional depreciation deduction equal to 30 percent of an asset’s ad-
justed basis. The Reconciliation Act increased this first-year addi-
tional depreciation deduction to 50 percent of an asset’s adjusted 
basis. The additional first-year depreciation deduction is an accel-
eration of depreciation deductions that otherwise would have been 
taken in the later years of an asset’s recovery period. The acceler-
ated depreciation provisions provided by both the Assistance Act 
and the Reconciliation Act expired at Dec. 31, 2004. The Company 
realized enhanced cash flow from reduced income taxes totaling 
an estimated $55 million during the effective period, based on plant 
investments made between Sept. 11, 2001 and Dec. 31, 2004.
Investing Activities
  Cash requirements for investing activities in 2004 totaled $136 
million, up from $128 million in the same period of 2003. Cash re-
quirements for the acquisition and construction of utility plant to-
taled $141 million, up from $125 million in 2003. The increase in 
cash requirements for utility construction in 2004 was primarily 
the result of higher capital expenditures relating to NW Natural’s 
SMPE project to extend the pipeline from its Mist gas storage field 
to  serve  growing  portions  of  its  service  area  ($22  million).  The 
SMPE was completed and placed into service in September 2004. 
The total cost of the project was approximately $110 million, which 
includes amounts reflected in investing activities over the past few 
years. The cost of service associated with the SMPE project, net of 
deferred tax benefits, was included in customer rates starting in 
the fourth quarter of 2004.
  Cash requirements for investing activities in 2003 totaled $128 
million, up from $85 million in 2002. Cash requirements for the 
acquisition and construction of utility plant totaled $125 million, 
up from $80 million in 2002. The increase in cash requirements 
for utility construction in 2003 was primarily the result of higher 
capital expenditures relating to the SMPE project ($27 million), 
higher system improvements and support ($12 million) and other 
special projects to serve new customer load or new service areas 
($9 million).

Investments in the Company’s pipeline integrity management 
program (IMP) were $1.6 million in 2004, compared to $0.9 mil-
lion in 2003. IMP costs are estimated at approximately $50 million 
to $100 million over a ten-year period (see discussion below). IMP 
costs are classified as either capital expenditures or regulatory as-
sets. The costs are accumulated over each 12-month period ending 
June 30, and the costs, subject to audit, are recovered through rate 
changes effective on Oct. 1 of each year commencing Oct. 1, 2004. 
The approved accounting and rate treatment for these costs extends 
through Sept. 30, 2008, and it may be reviewed for potential exten-
sion after that date.

Management’s Discussion and Analysis

Investments  in  non-utility  property  totaled  $10.6  million  in 
2004, compared to $2.6 million in 2003. The higher investments in 
2004 compared to 2003 were primarily for certain improvements 
to the Company’s gas pipeline system that were related to interstate 
gas storage services.

In December 2004, the Company received proceeds from the sur-
render of certain life insurance policies and proceeds from the set-
tlement of life insurance benefits totaling $17.6 million.
  During the five-year period 2005 through 2009, utility construc-
tion expenditures are estimated at between $500 million and $600 
million. The level of capital expenditures over the next five years 
reflects projected high customer growth and system improvement 
projects  resulting  in  part  from  requirements  under  the  Pipeline 
Safety Improvement Act of 2002 (Pipeline Safety Act) (see below). 
A majority of the required funds is expected to be internally gener-
ated over the five-year period; the remainder will be funded through 
a combination of long-term debt and equity securities with short-
term debt providing liquidity and bridge financing.
  NW Natural’s utility and non-utility capital expenditures in 2005 
are estimated to total $110 million, including $28 million for cus-
tomer growth, $21 million for system improvement and support, 
$15 million for equipment, facilities and information technology, 
$10 million for IMP costs, $6 million for the SMPE and related gas 
storage projects, $9 million for utility and non-utility storage and 
$21 million for construction overhead.

In  December  2003,  the  U.S.  Department  of  Transportation’s  
Office of Pipeline Safety issued a rule that specifies the detailed re-
quirements  for  transmission  pipeline  IMPs  as  mandated  by  the 
Pipeline Safety Act. The Pipeline Safety Act requires operators of 
gas transmission pipelines to identify lines located in High Conse-
quence Areas (HCAs) and to develop IMPs to periodically inspect 
the integrity of the pipelines and make repairs or replacements as 
necessary to ensure the ongoing integrity of the pipelines. The leg-
islation requires NW Natural to inspect the 50 percent highest risk 
pipelines located in its HCAs within the first five years, and to in-
spect the remaining covered pipelines within 10 years of the date 
of the enactment. The Pipeline Safety Act also requires re-inspec-
tions of the covered pipelines every seven years from the date of 
the previous inspection for the life of the pipelines.
Financing Activities
  Cash provided by financing activities in 2004 totaled $29 mil-
lion, compared to $17 million in 2003. Factors contributing to the 
$12 million increase were the net proceeds ($38.5 million) from a 
common stock offering in April 2004 (see below), combined with 
last year’s redemption of the $7.125 Series of Preferred Stock ($8.4 
million), offset by last year’s increase in long-term debt balances 
($35.0 million).
  Cash provided by financing activities in 2003 totaled $17 mil-
lion, compared to cash used in financing activities in 2002 of $43 
million. Factors contributing to the $60 million difference were an 
increase in short-term debt in 2003 ($15.4 million) compared to a 
decrease in 2002 ($38.5 million) and the redemption of the $6.95 
Series of Preference Stock in 2002 ($25 million), partially offset by 
a higher amount used for the retirement of long-term debt ($55 mil-
lion in 2003 compared to $40.5 million in 2002) and the redemp-
tion,  including  the  annual  sinking  fund,  of  the  $7.125  Series  of 
Preferred Stock in 2003 ($8.4 million).
  NW Natural sold $90 million of its secured Medium-Term Notes, 
Series B (MTNs) in each of 2003 and 2002 and used the proceeds 
to redeem long-term debt ($55 million in 2003 and $40.5 million 
in 2002), to provide cash for investments in utility plant and to re-
duce short-term borrowings.

In April 2004, the Company issued and sold 1,290,000 shares 
of its common stock in an underwritten public offering, and used 

30

N W   N AT U R A L

the net proceeds of $38.5 million from the offering to reduce short-
term  indebtedness  by  about  $29  million  and  to  fund,  in  part, 
NW Natural’s utility construction program. The offering of com-
mon  stock  was  made  pursuant  to  NW  Natural’s  universal  shelf 
registration statement providing for the registration of $200 million 
of securities, which became effective in February 2004. After the 
common stock offering, approximately $160 million remains avail-
able under the shelf registration statement for the Company to is-
sue additional securities, which may include First Mortgage Bonds 
and unsecured debt.

In 2000, NW Natural commenced a program to repurchase 
up to 2 million shares, or up to $35 million in value, of its com-
mon stock through a repurchase program that has been extended 
through May 2005. The purchases are made in the open market or 
through privately negotiated transactions. No shares were repur-
chased in 2003 or in 2004. Since the program’s inception the Com-
pany has repurchased 355,400 shares of common stock at a total 
cost of $8.2 million.
Pension Cost (Income) and Funding Status
  Net periodic pension cost (NPPC) is determined in accordance 
with SFAS No. 87, “Employers’ Accounting for Pensions” (see “Ap-
plication of Critical Accounting Policies – Accounting for Pensions,” 
above). The annual pension cost or income is allocated between 
operations and maintenance expense and construction overhead.
  NPPC for the Company’s two qualified defined benefit plans to-
taled $6.6 million in 2004, an increase of $0.4 million over NPPC 
for these plans of $6.2 million in 2003. The increased NPPC was 
primarily due to the use of a lower discount rate (6.25 percent in 
2004 compared to 6.75 percent in 2003) which had the effect of 
increasing the two plans’ accumulated benefit obligations.
  During 2004, the Company contributed $5.3 million to its Retire-
ment Plan for Non-Bargaining Unit Employees (NBU Plan) for plan 
year  2004,  of  which  $1.0  million  represented  the  minimum  re-
quired funding. The Company was not required to make any con-
tribution to its Retirement Plan for Bargaining Unit Employees (BU 
Plan) for that year. The Company’s funding policy is to contribute 
at least the minimum amount required by the Employee Retirement 
Income Security Act of 1974, as amended. For accounting expense 
recognition, the Company uses an asset valuation (market-related 
valuation)  method  that  spreads  variances  between  expected  re-
turns and actual investment returns over a three-year period, but 
for funding purposes the Company spreads these differences over 
a five-year period. In 2004, the Company made additional tax-de-
ductible contributions to improve the funded status of its qualified 
pension plans. In 2005, no contributions are required to be made 
to fund either the NBU Plan or the BU Plan, and the Company does 
not anticipate making any additional voluntary contributions for 
the 2004 plan year.
  The  fair  market  value  of  the  two  plans’  assets  increased  to 
$186.8 million at Dec. 31, 2004, up from $168.3 million at Dec. 31, 
2003. The increase included $22.5 million in investment gains and 
employer contributions of $8.3 million, which were offset in part 
by $11.2 million in withdrawals to pay benefits and $1.1 million in 
eligible expenses of the two plans. The present value of benefit 
obligations under the two plans increased from an estimated $192 
million to $209 million during 2004, however, so the two plans re-
mained under-funded in aggregate by about $22 million at Dec. 
31, 2004.
  NPPC for the NBU Plan and the BU Plan was $6.2 million in 
2003, compared to net periodic pension income of $0.1 million in 
2002. The increased NPPC in 2003 was largely due to investment 
losses in 2002, which are recognized over a three-year period, and 
to the use of a lower discount rate (6.75 percent in 2003 compared 
to 7.25 percent in 2002) which increased the plans’ accumulated 

 
 
 
 
 
benefit obligations. During 2004, the Company made a cash con-
tribution of $2.9 million to the NBU Plan for the 2003 plan year, of 
which $1.9 million represented the minimum required funding. No 
contributions were required to be made to either the NBU Plan or 
the BU Plan for the 2002 plan year.
  At Dec. 31, 2003, the fair market value of the assets of the NBU 
Plan and the BU Plan totaled $168.3 million, up from $143.2 mil-
lion at Dec. 31, 2002. The increased market value included $36 mil-
lion in investment gains, which was partially offset by $10 million 
in withdrawals to pay benefits and $0.9 million in eligible expenses 
of the plans. At Dec. 31, 2003, the present value of benefit obligations 
under the two plans totaled $192 million and thus were under-
funded in aggregate by about $24 million.
  Despite the increase in NPPC and the current under-funded sta-
tus of the NBU Plan, NW Natural believes it will be able to main-
tain  well-funded  qualified  pension  plans.  NW  Natural  does  not 
expect its current or future cash contribution requirements to the 
two plans to have a material adverse effect on its liquidity or finan-
cial condition (see Note 7).
Ratios of Earnings to Fixed Charges
  For the years ended Dec. 31, 2004, 2003 and 2002, the Compa-
ny’s ratios of earnings to fixed charges, computed using the Secu-
rities and Exchange Commission method, were 3.02, 2.84 and 2.85, 
respectively. For this purpose, earnings consist of net income be-
fore taxes plus fixed charges, and fixed charges consist of interest 
on all indebtedness, the amortization of debt expense and discount 
or premium and the estimated interest portion of rentals charged 
to income.

CONTINGENT LIABILITIES
Environmental Matters
  The Company is subject to federal, state and local laws and reg-
ulations related to environmental matters. These evolving laws and 
regulations may require expenditures over a long timeframe to con-
trol environmental impacts. The Company believes that appropri-
ate investigation or remediation is being undertaken at all the rel-
evant sites. Based on existing knowledge, the Company does not 
expect that the ultimate resolution of these matters will have a ma-
terial adverse effect on its financial condition, results of operations 
or cash flows (see Note 12).

In May 2003, the OPUC approved NW Natural’s request for de-
ferral  of  environmental  costs  associated  with  specific  sites.  The 
authorization, which has been extended through April 2005, allows 
NW Natural to defer and seek recovery of unreimbursed environ-
mental costs in a future general rate case. NW Natural has filed a 
request with the OPUC to extend this authority through January 
2006. On a cumulative basis through Dec. 31, 2004, the Company 
paid out a total of $3.3 million relating to the sites since the effec-
tive date of the deferral authorization (see Note 12).
  NW Natural will first seek to recover the costs of investigation 
and remediation for which it may be responsible with respect to 
environmental matters, if any, from insurance. If these costs are 
not recovered from insurance, then NW Natural will seek recovery 
through future rates subject to approval by the OPUC. At Dec. 31, 
2004, NW Natural had an $8.5 million receivable representing an 
estimate of the environmental costs it expects to incur and recover 
from insurance (see Note 12).

QUANTITATIVE AND QUALITATIVE DISCLOSURES  
ABOUT MARKET RISK
  The Company is exposed to various forms of market risk includ-
ing commodity supply risk, weather risk, and interest rate risk. The 
following describes the Company’s exposure to these risks.

Commodity Supply Risk
  NW Natural enters into short-term, medium-term and long-term 
natural gas supply contracts, along with associated short-, medium- 
and long-term transportation capacity contracts. Historically, NW 
Natural has taken physical delivery of at least the minimum quan-
tities specified in its natural gas supply contracts. These contracts 
are primarily index-based and subject to annual re-pricing, a pro-
cess that is intended to reflect anticipated market price trends dur-
ing the next year. NW Natural’s PGA mechanism in Oregon and 
Washington  provides  for  the  recovery  from  customers  of  actual 
commodity costs, except that, for Oregon customers, NW Natural 
absorbs 33 percent of the higher cost of gas sold, or retains 33 per-
cent of the lower cost, in either case as compared to the annual 
PGA price built into customer rates.
  To the degree that market risks exist due to potential adverse 
changes in commodity prices, foreign exchange rates or counter-
party credit quality in relation to these financial and physical con-
tracts, the Company considers the risks to be:
Commodity Price Risk
  The prices of natural gas commodity are subject to fluctuations 
due to unpredictable factors including weather, pipeline transpor-
tation congestion and other factors that affect short-term supply 
and demand. Commodity-price swap and call option contracts (fi-
nancial hedge contracts) are used to convert certain natural gas 
supply contracts from floating prices to fixed prices. These finan-
cial hedge contracts are included in the Company’s annual PGA 
filing, subject to a prudency review. At Dec. 31, 2004 and 2003, no-
tional amounts under these commodity swap and call option con-
tracts totaled $413.0 million and $304.1 million, respectively. At 
Dec. 31, 2004, five of these financial hedge contracts extended be-
yond Dec. 31, 2005. If all of the commodity-price swap and call op-
tion contracts had been settled on Dec. 31, 2004, a regulatory gain 
of $10.5 million would have been realized (see Note 11).
Foreign Currency Risk
  The costs of natural gas commodity and certain pipeline ser-
vices purchased from Canadian suppliers are subject to changes in 
the value of the Canadian currency in relation to the U.S. currency. 
Foreign currency forward contracts are used to hedge against fluc-
tuations in exchange rates with respect to the purchases of natural 
gas from Canadian suppliers. At Dec. 31, 2004 and 2003, notional 
amounts under foreign currency forward contracts totaled $14.5 
million and $6.4 million, respectively. As of Dec. 31, 2004, no for-
eign currency forward contracts extended beyond Dec. 31, 2005. If 
all of the foreign currency forward contracts had been settled on 
Dec. 31, 2004, a gain of $0.4 million would have been realized (see 
Note 11).
Counterparty Credit Risk
  Certain suppliers that sell gas to NW Natural have either rela-
tively low credit ratings or are not rated by major credit rating agen-
cies. To manage this supply risk, the Company purchases gas from 
a number of different suppliers, with no single supplier accounting 
for more than 20 percent of the Company’s total purchases for a 
given monthly period. The Company also evaluates suppliers’ cred-
itworthiness and maintains the ability to require additional financial 
assurances, including deposits, letters of credit, or surety bonds in 
case a supplier defaults. In the event of a supplier’s failure to deliver 
contracted volumes of gas, the regulated utility would need to re-
place  those  volumes  at  prevailing  market  prices,  which  may  be 
higher  or  lower  than  the  original  transaction  prices.  These  costs 
would be subject to the PGA sharing mechanism discussed above. 
Since most of the Company’s commodity supply contracts are priced 
at the monthly market index price, and the Company has significant 
storage flexibility, it is unlikely that a supplier default would have a 
materially adverse impact on the Company’s financial condition.

Management’s Discussion and Analysis

  With respect to the financial counterparties the Company uses 
for entering into commodity price hedge contracts, NW Natural’s 
Derivatives Policy requires each counterparty to be at least two rat-
ing grades above non-investment grade. Because counterparty rat-
ings are subject to change at any time, the Company could have 
contracts outstanding with counterparties whose ratings are non-
investment grade. NW Natural’s counterparty credit exposure as 
of Dec. 31, 2004 was as follows:

  $ 

  Due to the volatility of natural gas commodity prices, the mar-
ket value and credit exposure of certain derivative contracts could 
exceed the Company’s credit limits established in its Derivatives 
Policy. If such credit limits were exceeded, the Company would 
have  the  ability  to  require  collateral  from  the  counterparty  and 
would not enter into any further contracts with that counterparty 
until it was within the limits. If a counterparty failed to perform 
under its contract, NW Natural could sustain a loss which would 
be included in the annual PGA adjustment, subject to a regulatory 
prudency review. Under certain circumstances, a counterparty de-
fault could result in a material loss. However, based on the Com-
pany’s current regulatory mechanism, the absence of any signifi-
cant position with a single counterparty and the strength of the 
counterparties’ current credit ratings, any such loss is not expected 
to have a material impact on the Company’s financial condition.
Weather Risk
  The Company is exposed to weather risk primarily from its reg-
ulated utility business. A large portion of the Company’s net oper-

ating revenues (margin) is volume driven, and current rates are 
based on an assumption of normal weather. In 2003, the OPUC ap-
proved  a  weather  normalization  mechanism  for  residential  and 
commercial customers. This mechanism affects customer bills be-
tween Nov. 15 through May 15 of each winter heating season, in-
creasing or decreasing the margin component of customers’ rates 
to reflect “normal” weather using the 25-year average temperature 
for each day of the billing period. The mechanism is intended to 
stabilize the recovery of the utility’s fixed costs and reduce fluc-
tuations in customers’ bills due to colder or warmer than average 
weather. Customers in Oregon are allowed to opt out of the weather 
normalization mechanism. As of Dec. 31, 2004, about 8 percent of 
the Company’s Oregon customers had opted out. In addition to the 
Oregon customers opting out, the Company’s Washington custom-
ers are not covered by weather normalization. The combination of 
Oregon and Washington customers not covered by weather nor-
malization mechanism is less than 20 percent of all residential and 
commercial customers.
Interest Rate Risk
  The Company is exposed to interest-rate risk associated with 
new debt financing needed to fund capital requirements, including 
future  contractual  obligations  and  maturities  of  long-term  and 
short-term debt. Interest rate risk is managed through the issuance 
of fixed-rate debt with varying maturities and, if permitted, the re-
duction of debt through optional redemption when interest rates 
are favorable. At Dec. 31, 2004 and 2003, the Company had no vari-
able-rate long-term debt and no derivative financial instruments to 
hedge interest rates. Holders of certain long-term debt have put op-
tions that, if exercised, would accelerate maturities by $10 million 
in 2005 and by $20 million in each of 2007, 2008 and 2009.

Management’s Report on Internal Control over Financial Reporting

  Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as 
defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company’s internal control over financial re-
porting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial state-
ments for external purposes in accordance with generally accepted accounting principles in the United States of America (GAAP). The 
Company’s internal control over financial reporting includes those policies and procedures that:

(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions involving the assets 

of the Company;

(ii) provide reasonable assurance that transactions are recorded as necessary to permit the preparation of financial statements in ac-
cordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of 
management and the Board of Directors of the Company; and

(iii) provide reasonable assurance regarding prevention or timely detection of the unauthorized acquisition, use or disposition of the 

Company’s assets that could have a material effect on the financial statements.
  Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projec-
tions of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes 
in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
  Management assessed the effectiveness of the Company’s internal control over financial reporting as of Dec. 31, 2004. In making this 
assessment, management used the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission 
(COSO) in Internal Control-Integrated Framework.
  Based on our assessment and those criteria, management has concluded that the Company maintained effective internal control over 
financial reporting as of Dec. 31, 2004.
  Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of Dec. 31, 2004 has 
been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which ap-
pears herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders  
of Northwest Natural Gas Company:

  We have completed an integrated audit of Northwest Natural Gas Company’s 2004 consolidated financial statements and of its in-
ternal control over financial reporting as of December 31, 2004 and audits of its 2003 and 2002 consolidated financial statements in ac-
cordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, 
are presented below.

Consolidated financial statements

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, of shareholders’ 
equity and comprehensive income, of cash flows and of capitalization present fairly, in all material respects, the financial position of 
Northwest Natural Gas Company (doing business as NW Natural) and its subsidiaries (“the Company”) at December 31, 2004 and 2003, 
and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2004 in conformity 
with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the 
Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted 
our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are 
free of material misstatement. An audit of financial statements includes examining, on a test basis, evidence supporting the amounts 
and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, 
and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Internal control over financial reporting
  Also, in our opinion, management’s assessment, included in Management’s Report on Internal Control Over Financial Reporting ap-
pearing on page 32 of the 2004 Annual Report to Shareholders, that the Company maintained effective internal control over financial 
reporting as of December 31, 2004 based on criteria established in Internal Control – Integrated Framework issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Fur-
thermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of De-
cember 31, 2004, based on criteria established in Internal Control – Integrated Framework issued by the COSO. The Company’s man-
agement is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of 
internal control over financial reporting. Our responsibility is to express opinions on management’s assessment and on the effectiveness 
of the Company’s internal control over financial reporting based on our audit. We conducted our audit of internal control over financial 
reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require 
that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was 
maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal 
control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of 
internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit pro-
vides a reasonable basis for our opinions.
  A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted account-
ing principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the main-
tenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; 
(ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accor-
dance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accor-
dance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention 
or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the fi-
nancial statements.
  Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projec-
tions of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes 
in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
Organization and Principles of Consolidation
  The consolidated financial statements include the accounts of 
the regulated parent company, Northwest Natural Gas Company 
(NW Natural), and its non-regulated wholly-owned subsidiaries:
■  NNG Financial Corporation (Financial Corporation), and its 
wholly-owned subsidiaries
■  Northwest Energy Corporation (Northwest Energy), and its 
wholly-owned subsidiary
  Together these businesses are referred to herein as the “Com-
pany.” In this report, the term “utility” is used to describe the reg-
ulated  gas  distribution  business  of  the  Company  and  the  term 
“non-utility” is used to describe the interstate gas storage business 
and other non-regulated activities (see Note 2). Intercompany ac-
counts and transactions have been eliminated.

Investments  in  corporate  joint  ventures  and  partnerships  in 
which the Company’s ownership interest is 50 percent or less and 
over which the Company does not exercise control are accounted 
for by the equity method or the cost method (see Note 9).
  Certain amounts from prior years have been reclassified to con-
form, for comparison purposes, with the current financial state-
ment presentation. These reclassifications had no impact on prior 
year consolidated results of operations.
Use of Estimates
  The  preparation  of  financial  statements  in  conformity  with 
generally accepted accounting principles in the United States of 
America requires management to make estimates and assumptions 
that affect reported amounts in the consolidated financial state-
ments and accompanying notes. Actual amounts could differ from 
those estimates, and changes would be reported in future periods. 
Management believes that the estimates and assumptions used 
are reasonable.
Industry Regulation
  The Company’s principal business is the distribution of natural 
gas, which is regulated by the Public Utility Commission of Oregon 
(OPUC) and the Washington Utilities and Transportation Commis-
sion (WUTC). Accounting records and practices conform to the re-
quirements and uniform system of accounts prescribed by these 
regulatory authorities in accordance with Statement of Financial 
Accounting Standards (SFAS) No. 71, “Accounting for the Effects of 
Certain Types of Regulation.” NW Natural’s utility business seg-
ment is authorized by the OPUC and the WUTC to earn a reason-
able return on invested capital.

In applying SFAS No. 71, NW Natural capitalizes certain costs 
and revenues as regulatory assets and liabilities pursuant to orders 
of the OPUC or WUTC in general rate or expense deferral proceed-
ings, to provide for recovery of revenues or expenses from, or re-
funds to, utility customers in future periods, including a return or 
a carrying charge. At Dec. 31, 2004 and 2003, the amounts deferred 
as regulatory assets and liabilities were net liabilities of $80.8 mil-
lion and $89.4 million, respectively. The net amounts recognized 
at Dec. 31, 2004 and 2003 include $153.2 million and $135.6 mil-
lion, respectively, of accumulated removal costs, which have been 
included in regulatory liabilities, in accordance with SFAS No. 143, 
“Accounting for Asset Removal Obligations.” See “New Accounting 
Standards – Adopted Standards,” below.
  NW Natural believes that continued application of SFAS No. 71 
for its regulated activities is appropriate and consistent with the 
current regulatory environment, and that all of its regulated assets 
and liabilities at Dec. 31, 2004 and 2003 are recoverable or refund-
able through future utility rates. NW Natural also believes that it 
will continue to be able to earn a reasonable rate of return or a car-
rying charge on its regulated assets, net of regulatory liabilities.  

If NW Natural should determine that all or a portion of these regu-
latory assets or liabilities no longer meet the criteria for continued 
application of SFAS No. 71, then it would be required to write off 
the net unrecoverable balances against earnings.
New Accounting Standards
Adopted Standards
  ASSET RETIREMENT OBLIGATIONS. Effective Jan. 1, 2003, the Com-
pany  adopted  SFAS  No.  143,  “Accounting  for  Asset  Retirement 
Obligations.” SFAS No. 143 requires the recognition of an Asset 
Retirement Obligation (ARO) for legal obligations associated with 
the retirement of tangible long-lived assets, including the recording 
of fair value of the liability, if reasonably estimable, for an ARO in 
the period in which it is incurred. The ARO liability is recorded and 
the cost is capitalized as part of the carrying amount of the related 
long-lived asset. Over time, the liability is accreted to its present 
value each period and the capitalized cost is depreciated over the 
useful life of the related asset. The Company did not have any ma-
terial legal obligations associated with the retirement of its tangible 
long-lived assets, except for certain assets with indefinite system 
lives for which the Company cannot estimate the ARO because the 
settlement  date  is  indeterminable.  The  Company’s  adoption  of 
SFAS No. 143 resulted in a balance sheet reclassification of asset 
removal cost obligations from accumulated depreciation and amor-
tization to regulatory liabilities. The adoption of SFAS No. 143 and 
the reclassification of asset removal cost obligations had no mate-
rial impact on the Company’s financial condition, results of opera-
tions or cash flows (see “Plant and Property,” below, for a discus-
sion of the Company’s policy on asset removal costs).

FINANCIAL  INSTRUMENTS  WITH  EQUITY  AND  DEBT  CHARACTERIS-
TICS. Effective July 1, 2003, the Company adopted SFAS No. 150, 
“Accounting for Certain Financial Instruments with Characteristics 
of both Liabilities and Equity.” SFAS No. 150 establishes standards 
for how an issuer classifies and measures in its financial statements 
certain financial instruments with characteristics of both liabilities 
and equity. SFAS No. 150 requires an issuer to classify a financial 
instrument as a liability if that financial instrument embodies an 
obligation of the issuer. The adoption of SFAS No. 150 resulted in 
the Company’s reclassifying dividends of $0.2 million after July 1, 
2003 on its redeemable preferred stock as interest expense. The 
Company redeemed its remaining shares of preferred stock out-
standing during the fourth quarter of 2003. The adoption of SFAS 
No. 150 did not have a material impact on the Company’s financial 
condition, results of operations or cash flows.
  VARIABLE  INTEREST  ENTITIES.  In  December  2003,  the  Financial 
Accounting Standards Board (FASB) revised FASB Interpretation 
No.  (FIN)  46,  “Consolidation  of  Variable  Interest  Entities”  (FIN 
46R), to clarify the application of Accounting Research Bulletin No. 
51, “Consolidated Financial Statements.” FIN 46R provides addi-
tional guidance for the identification and consolidation of variable 
interest entities (VIEs), and for financial reporting by enterprises 
involved with VIEs. The Company adopted the original provisions 
of FIN 46 during 2003, and adopted the additional guidance of FIN 
46R in 2004. The Company has certain equity investments that are 
variable interests and some of these entities are potentially VIEs.

Notes to Consolidated Financial Statements

However, because the Company is not the primary beneficiary, it 
is not required to consolidate the VIEs. The Company’s variable 
interests primarily consist of limited liability interests with invest-
ments in alternative energy projects, low income housing and other 
real estate. These investments were entered into between the years 
1988  and  2000  and  have  been  accounted  for  under  the  equity 
method or cost method. The Company’s maximum exposure to 
loss for these investments is $6.2 million at December 31, 2004, an 
amount that represents the Company’s current investment balance 
minus its minimum net realizable value. The Company’s invest-
ment risk is thus limited because all such investments are non-re-
course to the Company. The adoption of FIN 46R had no material 
impact on the Company’s financial condition, results of operations 
or cash flows.
  MEDICARE PRESCRIPTION DRUG, IMPROVEMENT AND MODERNIZA-
TION ACT. In May 2004, the FASB issued Staff Position (FSP) No. 
FAS 106-2, “Accounting and Disclosure Requirements Related to 
the Medicare Prescription Drug, Improvement and Modernization 
Act of 2003,” (the Act). FSP No. FAS 106-2 provides specific guid-
ance on accounting for the effects of the Act for employers that 
sponsor postretirement health care plans that provide prescription 
drug benefits. FSP No. FAS 106-2 also requires certain disclosures 
regarding the effects of a federal subsidy provided by the Act.
  Effective July 1, 2004, the Company adopted FSP No. 106-2 with 
no  material  impact  on  the  Company’s  cash  flows,  accumulated 
postretirement benefit obligations or net periodic postretirement 
benefit costs. Based on current guidance and existing plan design, 
the Company, with input from its actuary, determined that the pre-
scription drug benefit provided by the Company’s postretirement 
benefit plan did not qualify it for a federal subsidy. While the Com-
pany provides certain prescription drug benefits to retirees, it was 
determined that the Company’s contributions would be less than 
40 percent of the plan’s expected claims cost, and therefore is not 
eligible for the subsidy in 2006, the first year the subsidy is avail-
able. The Company will continue to reevaluate its plan contribu-
tions and claims experience to determine whether the plan quali-
fies for the federal subsidy in future years.
  OTHER  THAN  TEMPORARY  IMPAIRMENTS.  In  March  2004,  the 
Emerging  Issues  Task  Force  (EITF)  ratified  EITF  No.  03-1,  “The 
Meaning of Other-Than-Temporary Impairment and Its Application 
to Certain Investments” (EITF No. 03-1). EITF No. 03-1 provides 
guidance for evaluating whether an investment is impaired, whether 
the impairment is other than temporary, and the measurement of 
such impairment. The guidance also includes accounting consid-
erations subsequent to the recognition of an other-than-temporary 
impairment  and  requires  certain  disclosures  in  annual  financial 
statements about unrealized losses that have not been recognized 
as other-than-temporary impairments. The adoption of EITF 03-1, 
which was effective for reporting periods beginning after June 15, 
2004, had no material impact on the Company’s financial condi-
tion, results of operations or cash flows.

INCOME TAXES. In December 2004, the FASB issued staff posi-
tions (FSP) FSP SFAS No. 109-1, to provide guidance on the appli-
cation of SFAS No. 109, “Accounting for Income Taxes,” to the pro-
visions within the American Jobs Creation Act of 2004 (the Jobs 
Act) that provides a tax deduction on qualified production activi-
ties. The Jobs Act became effective on Oct. 23, 2004 and provides 
for a tax deduction of up to nine percent (when fully phased-in) of 
the lesser of (a) “qualified production activities income,” as defined 
in the Jobs Act, or (b) taxable income (after the deduction for the 
utilization of any net operating loss carryforwards). The Company 
has determined that application of the provisions within the Jobs 
Act will not have a material impact on the Company’s financial 
condition, results of operations or cash flows.
Recent Accounting Pronouncements

INVENTORY COSTS. In November 2004, the FASB issued SFAS No. 
151, “Inventory Costs, an amendment of ARB No. 43, Chapter 4.” 
SFAS No. 151 amends the guidance on inventory pricing to require 
that abnormal amounts of idle facility expense, freight, handling 
costs and wasted material be charged to current period expense 
rather than capitalized as inventory costs. SFAS No. 151 also re-
quires that allocation of fixed production overheads to the costs of 
conversion be based on the normal capacity of the production fa-
cilities. SFAS No. 151 is effective for inventory costs incurred dur-
ing  fiscal  years  beginning  after  June  15,  2005.  The  Company  is 
evaluating the impact this new standard may have on its financial 
statements, but it is expected that its implementation will not have 
a material impact upon the Company’s financial condition, results 
of operations or cash flows.

SHARE  BASED  PAYMENTS.  In  December  2004,  the  FASB  issued 
SFAS No. 123 (revised 2004), “Share Based Payment” (SFAS No. 
123R), that requires companies to expense the fair value of em-
ployee stock options and similar awards. Under SFAS No. 123R, 
share based payment awards will be measured at fair value on the 
date of grant based on the estimated number of awards expected 
to vest. The estimated fair value will be recognized as compensa-
tion expense over the period an employee is required to provide 
service in exchange for the award, usually referred to as the vest-
ing period. The expense would be adjusted for actual forfeitures 
that occur before vesting, but would not be adjusted for awards 
that expire or terminate after vesting. The Company is evaluating 
different option-pricing models to determine the most appropriate 
measure of fair value for its share based payment awards under 
the new standard. Disclosures of estimated fair value and compen-
sation expense using the Black-Scholes option pricing model, and 
its corresponding impact on the financial statements, is provided 
in Note 4. The Company also is evaluating the effect of the adop-
tion and implementation of SFAS No. 123R, which is not expected 
to have a material impact on the Company’s financial condition, 
results of operations or cash flows. SFAS No. 123R is effective for 
interim or annual reporting periods beginning after June 15, 2005. 
The Company expects to adopt the provisions of SFAS No. 123R in 
the first quarter of 2005.
  NON-MONETARY  TRANSACTIONS.  Also  in  December  2004,  the 
FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets, an 
amendment of Accounting Principles Board (APB) Opinion No. 29, 
Accounting for Nonmonetary Transactions.” SFAS No. 153 redefines 
the types of nonmonetary exchanges that require fair value mea-
surement. SFAS No. 153 is effective for nonmonetary transactions 
entered into on or after July 1, 2005. The Company is evaluating the 
impact of this statement, but adoption of this new accounting stan-
dard in 2005 is not expected to have a material impact on the Com-
pany’s financial condition, results of operations or cash flows.

 
 
 
Plant and Property
  Plant and property is stated at cost, including labor, materials 
and overhead (see Note 9). The cost of utility plant and interstate 
storage includes an allowance for funds used during construction 
in  construction  overhead  to  represent  the  net  cost  of  borrowed 
funds used for construction purposes (see “Allowance for Funds 
Used During Construction,” below).
  NW Natural’s provision for depreciation of utility property is 
computed under the straight-line, age-life method in accordance 
with independent engineering studies and as approved by regula-
tory authorities. The weighted average depreciation rate was ap-
proximately 3.4 percent for the year ended Dec. 31, 2004 and 3.5 
percent for each of the years 2003 and 2002. The depreciation rate 
reflects the approximate economic life of the utility property.
  Effective Jan. 1, 2003, the Company adopted SFAS No. 143, “Ac-
counting for Asset Retirement Obligations.” Among other things, 
SFAS No. 143 requires that future asset retirement costs (removal 
costs) that meet the requirements of SFAS No. 71, as amended and 
supplemented, be classified as a regulatory liability. In accordance 
with long-standing industry practice, the Company accrues for fu-
ture removal costs on many long-lived assets through a charge to 
depreciation expense allowed in rates. Prior to the adoption of SFAS 
No. 143, the resulting regulatory liabilities were recognized as ac-
cruals  to  accumulated  depreciation.  At  the  time  when  removal 
costs were incurred, accumulated depreciation was charged with 
the costs of removal and the book cost of the asset being retired. 
At Dec. 31, 2004 and 2003, the Company recognized accrued asset 
removal costs of $153.2 million and $135.6 million, respectively, 
through depreciation expense from accumulated depreciation and 
amortization.  The  Company’s  estimate  of  accumulated  removal 
costs was based on rates using its most recent depreciation study. 
The Company will continue to accrue future asset removal costs 
through depreciation expense, with a corresponding credit to regu-
latory liabilities – accrued asset removal costs. When the Company 
retires depreciable utility plant and equipment, it charges the as-
sociated original costs to accumulated depreciation and amortiza-
tion, and any related removal costs incurred are charged to regula-
tory liabilities – accrued asset removal costs. No gain or loss is 
recognized upon normal retirement. In the rate setting process, the 
accrued asset removal costs are treated as a reduction to the net 
rate base.
Allowance for Funds Used During Construction
  Certain additions to utility plant include an allowance for funds 
used during construction (AFUDC). AFUDC represents the cost of 
funds borrowed during construction and is calculated using actual 
commercial paper interest rates. If commercial paper borrowings are 
less than the total costs of construction work in progress, then a 
composite rate of interest on all debt, shown as a reduction to inter-
est charges, and a return on equity funds, shown as other income, 
is used to compute AFUDC. While cash is not realized currently 
from AFUDC, it is realized in future years through increased reve-
nues from rate recovery resulting from higher rate base and higher 
depreciation expense. NW Natural’s composite AFUDC rates were 
3.0 percent in 2004, 4.5 percent in 2003 and 2.8 percent in 2002.
Cash and Cash Equivalents
  For purposes of reporting cash flows, cash and cash equivalents 
include  cash  on  hand  and  highly  liquid  temporary  investments 
with original maturity dates of three months or less.
Revenue Recognition
  Utility revenues, derived primarily from the sale and transpor-
tation of natural gas, are recognized when the gas is delivered to 
and received by the customer. Revenues include accruals for gas 
delivered but not yet billed to customers based on estimates of gas 

deliveries from meter reading dates to month end (unbilled reve-
nues). Unbilled revenues are dependent upon a number of factors 
that  require  management  judgment,  including  total  gas  receipts 
and deliveries, customer use and weather. Unbilled revenues are 
reversed the following month when actual billings occur. The Com-
pany’s accrued unbilled revenues at Dec. 31, 2004 and 2003 were 
$64.4 million and $59.1 million, respectively.
  Non-utility revenues, derived primarily from gas storage services, 
are recognized upon delivery of the service to customers. Revenues 
from optimization of excess storage and transportation capacity are 
recognized over the life of the contract for guaranteed amounts un-
der the contract, or are recognized as they are earned for amounts 
above the guaranteed value based on estimates provided by the in-
dependent energy marketing company (see Note 2).
Accounts Receivable and Allowance for  
Uncollectible Accounts
  Accounts receivable consist primarily of amounts due to NW 
Natural  for  gas  sales  and  transportation  services  to  residential, 
commercial and industrial customers, plus amounts due for inter-
state  gas  storage  services  and  other  miscellaneous  receivables. 
With respect to these trade receivables, the Company establishes 
an allowance for uncollectible accounts (allowance) based on the 
aging of receivables, its collection experience of past due accounts 
on payment plans, and historical trends of write-offs as a percent 
of revenues. With respect to large individual customer receivables, 
a specific allowance is established and added to the general allow-
ance when amounts are identified as unlikely to be recovered. In-
active accounts are written-off against the allowance after 120 days 
past due or when deemed to be uncollectible. Differences between 
the Company’s estimated allowance and actual write-offs will oc-
cur based on changes in general economic conditions, customer 
credit issues and the level of natural gas prices, but these differ-
ences are not currently expected to have a material impact on the 
Company’s financial condition or results of operation.
Inventories

Inventories, consisting primarily of natural gas in storage, are 
stated at the moving average cost. Regulatory treatment of gas in-
ventories provides full recovery in rates for the value of gas inven-
tory at the moving average cost. All other inventories are stated at 
the lower of average cost or net realizable value.
Derivatives Policy
  NW Natural’s Derivatives Policy sets forth the guidelines for us-
ing selected financial derivative products to support prudent risk 
management strategies within designated parameters. The Deriva-
tives Policy allows for the use of derivatives to manage natural gas 
commodity  prices  related  to  natural  gas  purchases,  foreign  cur-
rency prices related to gas purchase commitments from Canada, 
oil or propane commodity prices related to gas sales and transpor-
tation services under rate schedules pegged to other commodities, 
and interest rates related to long-term debt maturing in less than 
five years or expected to be issued in future periods. NW Natural’s 
objective for using derivatives is to decrease the volatility of earn-
ings and cash flows associated with changes in commodity prices, 
foreign currency prices and interest rates. The use of derivatives is 
permitted only after the commodity price, exchange rate, and in-
terest rate exposures have been identified, are determined to exceed 
acceptable tolerance levels and are considered to be unavoidable 
because they are necessary to support normal business activities 
(see Note 11). The Derivatives Policy is intended to prevent specu-
lative risk. NW Natural does not enter into derivative instruments 
for trading purposes and believes that any increase in market risk 
created by holding derivatives should be offset by the exposures 
they modify.

Notes to Consolidated Financial Statements

In  accounting  for  derivative  activities,  the  Company  applies 
SFAS No. 133, “Accounting for Derivative Instruments and Hedg-
ing Activities,” as amended by SFAS No. 138, “Accounting for Cer-
tain Derivative Instruments and Certain Hedging Activities,” and 
SFAS No. 149, “Amendment of Statement 133 on Derivative Instru-
ments and Hedging Activities,” (collectively referred to as SFAS No. 
133). SFAS No. 133 requires that the Company recognize deriva-
tives as either assets or liabilities on the balance sheet and measure 
those instruments at fair value. SFAS No. 133 also requires that 
changes in the fair value of a derivative be recognized currently in 
earnings unless specific hedge accounting criteria are met. SFAS 
No. 133 provides an exception for contracts intended for normal 
purchase and normal sale, other than a financial instrument or de-
rivative instrument for which physical delivery is probable. Many 
of the Company’s gas supply and transportation contracts are de-
rivative instruments as defined under SFAS No. 133, but qualify 
for the normal purchase and normal sale exception.
  NW Natural designates its derivatives as fair value or cash flow 
hedges based upon the criteria established by SFAS No. 133. For 
fair value hedges, the gain or loss is recognized in earnings in the 
period of change. For cash flow hedges, the effective portion of the 
gain or loss is initially reported in accumulated other comprehen-
sive income (OCI), unless the derivative is subject to deferral under 
NW Natural’s regulated tariffs with the OPUC or the WUTC. The 
ineffective portion of the gain or loss in a cash flow hedge is rec-
ognized in current earnings, but only to the extent that the amount 
is not covered under NW Natural’s regulatory deferral mechanisms. 
Effectiveness is measured by comparing changes in cash flows of 
the hedged item to gains or losses on derivative instruments.
  NW Natural’s primary hedging activities, consisting of natural 
gas commodity price and foreign currency exchange rate hedges, 
are principally accounted for as cash flow hedges under SFAS No. 
133 and are subject to regulatory deferral under SFAS No. 71. Un-
realized gains and losses from mark-to-market valuations of these 
contracts are not recognized in current income but are reported as 
derivative assets or liabilities and offset by a corresponding deferred 
account balance included under “regulatory liabilities” or “regula-
tory assets.” Due to their regulatory deferral treatment, effective 
portions of changes in the fair value of these derivatives are not re-
corded in OCI but are recognized as a regulatory asset or liability.
Income Taxes
  The Company accounts for income taxes in accordance with 
SFAS No. 109, “Accounting for Income Taxes.” Under SFAS No. 109, 
the Company recognizes deferred income taxes for all temporary 
differences between the financial statement and tax basis of assets 
and liabilities at current income tax rates. Deferred tax liabilities 
and assets reflect the expected future tax consequences, based on 
enacted tax law, of temporary differences between the tax basis of 
assets  and  liabilities  and  their  financial  reporting  amounts  (see 
Note 8).
  SFAS No. 109 also requires recognition of the additional deferred 
income tax assets and liabilities for temporary differences where 
regulators prohibit deferred income tax treatment for ratemaking 
purposes. Consistent with rate and accounting orders of regulatory 
authorities, deferred income taxes are not currently collected for 
those temporary income tax differences where the prescribed reg-
ulatory accounting methods do not provide for current recovery in 
rates. NW Natural has recorded a regulatory tax asset for amounts 
pending  recovery  from  customers  in  future  rates,  equivalent  to 
$64.7 million and $63.4 million at Dec. 31, 2004 and 2003, respec-
tively. These amounts are primarily based on differences between 
the book and tax bases of net utility plant in service.

N W   N AT U R A L

Investment tax credits on utility plant additions and leveraged 
leases, which reduce income taxes payable, are deferred for finan-
cial statement purposes and are amortized over the life of the re-
lated plant or lease. Investment and energy tax credits generated 
by non-regulated subsidiaries are amortized over a period of one 
to five years.
Other Income (Expense)
  Other income (expense) consists of interest income, gain on sale 
of assets, investment income of Financial Corporation, the costs 
incurred in connection with the Company’s effort to acquire Port-
land General Electric Company (PGE) from Enron Corp. and other 
miscellaneous income from merchandise sales, rents, leases and 
other items.
Earnings Per Share
  Basic earnings per share are computed based on the weighted 
average number of common shares outstanding each year. Diluted 
earnings per share reflect the potential effects of the conversion of 
convertible debentures and the exercise of stock options. Diluted 
earnings per share are calculated as follows:

the number of stock options the exercise prices for which were 
greater than the average market prices for the Company’s common 
stock for such years, were excluded from the calculation of diluted 
earnings per share because the effect was antidilutive.
Stock-Based Compensation
  The  Company  applies  APB  Opinion  No.  25,  “Accounting  for 
Stock Issued to Employees,” to account for its stock-based com-
pensation  plans.  Accordingly,  the  Company  does  not  recognize 
compensation expense for the fair value of its stock option grants. 
Instead, the Company has elected to continue using the intrinsic 
value method of accounting for stock options rather than adopting 
the fair value method of accounting. However, the Company does 
recognize compensation expense for the fair value of stock awards 
granted under its Long-Term Incentive Plan and the Non-Employee 
Directors Stock Compensation Plan in the period when the shares 
are earned (see “New Accounting Standards – Recent Accounting 
Pronouncements – Share Based Payments,” above, and Note 4).

 
 
 
 
 
     
 
 
 
 
 
 
     
     
     
 
 
 
 
 
 
 
 
 
     
 
 
 
     
     
     
     
     
     
2.  CONSOLIDATED SUBSIDIARY OPERATIONS AND 
SEGMENT INFORMATION:
  At Dec. 31, 2004, the Company had two direct, wholly-owned 
subsidiaries, Financial Corporation and Northwest Energy. North-
west Energy was formed in 2001 to serve as the holding company 
for NW Natural and PGE if the acquisition of PGE had been com-
pleted. Since the acquisition of PGE was terminated, Northwest 
Energy has remained a non-active subsidiary of the Company.
  The Company’s core business segment, Local Gas Distribution 
(LDC), involves the distribution and sale of natural gas. The Local 
Gas Distribution segment is also referred to as the “utility”. Another 
segment, Interstate Gas Storage, represents natural gas storage ser-
vices provided to interstate customers, including asset optimiza-
tion services under a contract with an independent energy market-
ing company. The remaining business segment, Other, primarily 
consists of non-regulated investments in alternative energy proj-
ects in California (see “Financial Corporation,” below), a Boeing 
737-300 aircraft leased to Continental Airlines, low-income hous-
ing in Portland, Oregon and Northwest Energy’s limited activities 
(see Note 9).
Interstate Gas Storage

Interstate gas storage services are provided to off-system inter-
state customers using Company-owned storage capacity that has 
been developed in advance of core utility customers’ (residential, 
commercial and industrial firm) requirements. NW Natural retains 
80 percent of the income before tax from gas storage services and 
credits the remaining 20 percent to a deferred regulatory account 
for sharing with its core utility customers. For each of the years 
ended Dec. 31, 2004, 2003 and 2002, this business segment derived 
a majority of its revenues from fewer than five customers. The larg-
est of these customers is served under a long-term contract.
  Results for the interstate gas storage segment also include rev-
enues, net of amounts shared with core utility customers, from a 
contract with an independent energy marketing company that op-
timizes the use of NW Natural’s assets by engaging in trading ac-
tivities using temporarily unused portions of its upstream pipeline 
transportation capacity and gas storage capacity. In Oregon, NW 
Natural retains 80 percent of the pre-tax income from the optimi-
zation of storage and pipeline transportation capacity when the 
costs of such capacity have not been included in core utility rates, 
and 33 percent of the pre-tax income from such capacity when the 
costs have been included in core utility rates. The remaining 20 
percent and 67 percent, respectively, are credited to a deferred reg-
ulatory account for distribution to NW Natural’s core utility cus-
tomers. NW Natural has a similar sharing mechanism in Washing-
ton for revenue derived from interstate storage services and third 
party optimization services.
Financial Corporation
  Financial Corporation has several financial investments, includ-
ing  investments  as  a  limited  partner  in  solar  electric  generating 
systems, windpower electric generating projects and low-income 
housing  projects.  Financial  Corporation’s  total  assets  were  $7.6 
million and $8.0 million at Dec. 31, 2004 and 2003, respectively.
  On Jan. 31, 2005 Financial Corporation sold its limited partner-
ship interests in three solar electric generating systems for approx-
imately $3 million, which resulted in a $0.5 million write-down of 
these systems in the fourth quarter of 2004. These systems are lo-
cated in the Mojave Desert in California. NW Natural invested in 
the projects between 1986 and 1988. Financial Corporation’s own-
ership interests ranged from 4.0 percent to 5.3 percent.

3.  CAPITAL STOCK:
Common Stock
  At Dec. 31, 2004, NW Natural had reserved 106,699 shares of 
common stock for issuance under the Employee Stock Purchase 
Plan, 288,155 shares for future conversions of its 7-1/4% Convert-
ible Debentures, 232,827 shares under its Dividend Reinvestment 
and Stock Purchase Plan, 1,659,470 shares under its Restated Stock 
Option Plan (see Note 4), and 3,000,000 shares under the Share-
holder Rights Plan.

In April 2004, the Company issued and sold 1,290,000 shares 
of its common stock in an underwritten public offering and used 
the net proceeds of $38.5 million from the offering primarily to re-
duce short-term indebtedness and to fund, in part, NW Natural’s 
utility construction program.
Redeemable Preferred Stock
  On Nov. 14, 2003, NW Natural redeemed all of the remaining 
shares of its $7.125 Series of Redeemable Preferred Stock with an 
aggregate stated value of $7.5 million, at a redemption price equiv-
alent to 102.375 percent with proceeds from sales of commercial 
paper. The Company re-financed the commercial paper with the 
sale of new long-term debt in the fourth quarter of 2003. The early 
redemption premium was recognized as an unamortized cost pur-
suant to SFAS No. 71 and is being amortized to expense over the 
life of the new debt.
Redeemable Preference Stock
  On Dec. 31, 2002, NW Natural redeemed all 250,000 shares of 
its $6.95 Series of Redeemable Preference Stock with proceeds from 
the sale of commercial paper.

Notes to Consolidated Financial Statements

Stock Repurchase Program
  NW Natural’s Board of Directors approved a stock repurchase 
program in 2000 to purchase up to 2 million shares, or up to $35 
million in value, of NW Natural’s common stock in the open mar-
ket or through privately negotiated transactions. The repurchase 
program has been extended through May 2005. No shares were re-
purchased in 2003 or 2004. Since the program’s inception, the Com-
pany has repurchased 355,400 shares of common stock at a total 
cost of $8.2 million.
Restated Stock Option Plan

In May 2002, the shareholders approved an amendment to the 
Restated  Stock  Option  Plan  that  increased  the  total  number  of 
shares authorized for option grants from 1,200,000 to 2,400,000 
shares. At Dec. 31, 2004, options on 1,228,000 shares were avail-
able for grant and options on 431,470 shares were outstanding.
  The following table shows the changes in the number of shares 
of NW Natural’s capital stock and the premium on common stock

4.  STOCK-BASED COMPENSATION:
  NW Natural has the following stock-based compensation plans: 
the Long-Term Incentive Plan (LTIP); the Restated Stock Option 
Plan (Restated SOP); the Employee Stock Purchase Plan (ESPP); 
and the Non-Employee Directors Stock Compensation Plan (NED-
SCP). These plans are designed to promote stock ownership in NW 
Natural by employees and officers and, in the case of the NEDSCP, 
by non-employee directors.

LONG-TERM INCENTIVE PLAN. The LTIP is intended to provide a 
flexible, competitive compensation program for eligible officers. An 
aggregate of 500,000 shares of common stock was authorized for 
grants under the LTIP as stock bonus, restricted stock or perfor-
mance-based  stock  awards.  Shares  awarded  under  the  LTIP  are 
purchased on the open market.

44

N W   N AT U R A L

  At year-end 2004, a total of 436,000 shares of common stock 
were available for award under the LTIP, assuming that current 
performance based grants are awarded at the target level. The LTIP 
stock awards are compensatory awards for which compensation 
expense is recognized based on the market value of performance 
shares earned, or a pro rata amortization over the vesting period 
for the restricted stock awards.

Performance-based Stock Awards. Since the Plan’s inception in 
2001, through December 31, 2004, five performance-based stock 
awards have been granted, one based on a two-year performance 
period (2001-02) and four based on three-year performance periods 
(2001-03, 2002-04, 2003-05 and 2004-06). At Dec. 31, 2004, all per-
formance-based stock awards other than those covering the 2003-
05 and 2004-06 periods had lapsed because the performance-based 
measures were not achieved. If the performance-based measures 
are achieved, participants will also receive dividend equivalent cash 
payments equal to the number of shares of common stock received 
on the award payout multiplied by the aggregate cash dividends 
paid per share by the Company during the performance period.
  At Dec. 31, 2004, the aggregate number of performance-based 
shares awarded and outstanding at the minimum, threshold, target 
and maximum levels were as follows:
Performance 
Year  
Period 
Awarded 

–––––––– No. of Performance Shares Awarded ––––––––
Target  Maximum
Minimum 

Threshold 

  For the 2003-05 performance period, a series of performance 
targets were established based on the Company’s average annual 
return on equity (ROE) for the performance period corresponding 
to award opportunities ranging from 0 percent to 200 percent of 
the target awards. No awards are payable unless the threshold an-
nual average ROE level, tied to the Company’s authorized ROE, is 
achieved during the award period. The maximum awards are pay-
able only upon the achievement of an average annual ROE 200 ba-
sis points above the Company’s authorized ROE. For the 2004-06 
performance period, awards will be based on total shareholder re-
turn relative to a peer group of gas distribution companies over the 
three-year performance period and performance milestones rela-
tive to the Company’s core and non-core strategies.
  Restricted Stock Awards. Restricted stock awards also have been 
granted under the LTIP. A restricted stock award consisting of 4,500 
shares granted in 2001 lapsed in 2004, and a restricted stock award 
was granted in 2004 consisting of 5,000 shares that is scheduled to 
vest ratably over five years beginning in 2005.

RESTATED STOCK OPTION PLAN. The Restated SOP authorizes an 
aggregate of 2,400,000 shares of common stock for issuance as in-
centive  or  non-statutory  stock  options.  These  options  may  be 
granted only to officers and key employees designated by a com-
mittee of NW Natural’s Board of Directors. All options are granted 
at an option price not less than the market value at the date of grant 
and may be exercised for a period not exceeding 10 years from the 
date  of  grant.  Option  holders  may  exchange  shares  they  have 
owned for at least six months, at the current market price, to pur-
chase shares at the option price. Since inception in 1985, options 
on 1,303,721 shares of common stock have been granted at prices 
ranging from $11.75 to $32.02 per share, and options on 131,721 
shares have expired.

EMPLOYEE STOCK PURCHASE PLAN. The ESPP allows employees 
to purchase common stock at 85 percent of the closing price on 
the  trading  day  immediately  preceding  the  subscription  date, 
which is set annually. Each eligible employee may purchase up to 
$24,000 worth of stock through payroll deductions over a six- to 
12-month period.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     
 
 
     
     
 
 
 
 
In accordance with APB Opinion No. 25, no compensation ex-
pense was recognized for options granted under the Restated SOP 
or shares issued under the ESPP during 2004 or earlier years (see 
Note 1, “New Accounting Standards – Recent Accounting Pronounce-
ments”). If compensation expense for awards under these two plans 
had been determined based on fair value at the grant dates using 
the method prescribed by SFAS No. 123, “Accounting for Stock-
Based Compensation,” net income and earnings per share would 
have been reduced to the pro forma amounts shown below:

  NON-EMPLOYEE DIRECTORS STOCK COMPENSATION PLAN. In Feb-
ruary 2004, the NEDSCP was amended to permit non-employee 
directors  to  receive  stock  awards  either  in  cash  or  in  Company 
stock. As a result of modifications to the directors’ compensation 
arrangements,  the  NEDSCP  was  further  amended  in  September 
2004 to eliminate any further awards, either in cash or stock, on 
and after Jan. 1, 2005.
  Prior to the latter amendment to the NEDSCP, if non-employee 
directors elected to receive their awards in stock, approximately 
$100,000  worth  of  the  Company’s  common  stock  was  awarded 
upon joining the Board. These stock awards were subject to vest-
ing and to restrictions on sale and transferability. The shares vested 
in monthly installments over the five calendar years following the 
award. On January 1 of each year following the initial award, non-
employee directors who elected to receive their awards in Company 
stock were awarded an additional $20,000 worth of restricted Com-
pany stock, which vested in monthly installments in the fifth year 
following the award (after the previous award has fully vested). 
The Company holds the certificates for the restricted shares until 
the non-employee director ceases to be a director. Participants re-
ceive all dividends and have full voting rights on both vested and 
unvested shares. All awards vest immediately upon a change in 
control of the Company. Any unvested shares are considered to be 
unearned  compensation,  and  thus  are  forfeited  if  the  recipient 
ceases to be a director. The shares were purchased in the open 
market by the Company at the time of the award.
  The  following  table  presents  the  changes  in  unearned  stock 
compensation for the years 2004 and 2003, which are reported as 
a reduction to total common equity in the consolidated balance 
sheets:

  Under a separate plan, prior to Jan. 1, 2005, non-employee di-
rectors could elect to invest their cash fees and retainers for board 
service in shares of the Company’s common stock. Under a new 
deferral plan effective Jan. 1, 2005, such fees and retainers will be 
deferred to a cash account. Cash account balances may be trans-
ferred to and invested in a Company stock account, at the election 
of the director, up to four times per year.

Notes to Consolidated Financial Statements

5.  LONG-TERM DEBT:
  The issuance of first mortgage debt, including secured medium-
term notes, under the Mortgage and Deed of Trust (Mortgage), is 
limited by property additions, adjusted net earnings and other pro-
visions of the Mortgage. The Mortgage constitutes a first mortgage 
lien on substantially all of NW Natural’s utility property.
  The 7-1/4% Series of Convertible Debentures may be converted 
at any time into 50-1/4 shares of common stock for each $1,000 
face value ($19.90 per share).
  The maturities on the long-term debt outstanding, for each of 
the 12-month periods through Dec. 31, 2009 amount to: $15 million 
in 2005; $8 million in 2006; $29.5 million in 2007, $5 million in 
2008; and none in 2009. Holders of certain long-term debt have put 
options that, if exercised, would accelerate the maturities by $10 
million in 2005 and $20 million in each of 2007, 2008 and 2009.

6.  NOTES PAYABLE AND LINES OF CREDIT:
  The Company’s primary source of short-term funds is commer-
cial paper notes payable. NW Natural issues commercial paper un-
der agency agreements with a commercial bank and such commer-
cial paper is supported by its committed bank lines of credit (see 
below). At Dec. 31, 2004 and 2003, the amounts and average inter-
est rates of commercial paper debt outstanding were $102.5 million 
and 2.3 percent and $85.2 million and 1.1 percent, respectively.
  NW Natural has lines of credit with four commercial banks to-
taling $150 million. Half of the credit facility with each bank, total-
ing $75 million, is committed and available through Sept. 30, 2005, 
and the other $75 million is committed and available through Sept. 
30, 2007. Three of these commercial banks have each committed 
$20 million for each of their 2005 and 2007 lines of credit and the 
fourth commercial bank has committed $15 million for each of its 
2005 and 2007 lines of credit.
  NW Natural’s lines of credit require that credit ratings be main-

tained in effect at all times and that notice be given of any change 
in its senior unsecured debt ratings. A change in NW Natural’s 
credit rating is not an event of default, nor is the maintenance of a 
specific minimum level of credit rating a condition to drawing upon 
the lines of credit. However, interest rates on any loans outstand-
ing under NW Natural’s bank lines are tied to credit ratings, which 
would increase or decrease the cost of bank debt, if any, when rat-
ings are changed.
  The lines of credit require the Company to maintain an indebt-
edness to total capitalization ratio of 65 percent or less and to main-
tain a consolidated net worth at least equal to 80 percent of its net 
worth at Sept. 30, 2004, plus 50 percent of the Company’s net in-
come for each subsequent fiscal quarter. Failure to comply with 
either of these covenants would entitle the banks to terminate their 
lending commitments and to accelerate the maturity of all amounts 
outstanding. The Company was in compliance with both of these 
covenants at Dec. 31, 2004, and with the equivalent covenants in 
the prior year’s lines of credit at Dec. 31, 2003.

7.  PENSION AND OTHER POSTRETIREMENT BENEFITS:
  NW Natural maintains two qualified non-contributory defined 
benefit pension plans covering all regular employees with more 
than one year of service, several non-qualified supplemental pen-
sion plans for eligible executive officers and certain key employees 
and other postretirement benefit plans for its employees. Only the 
two qualified defined benefit pension plans have plan assets which 
are held in a qualified trust to fund retirement benefits.
  The following table provides a reconciliation of the changes in 
benefit obligations and fair value of assets, as applicable, for the 
pension plans and other postretirement benefit plans over the three-
year period ended Dec. 31, 2004, and a statement of the funded 
status and amounts recognized in the consolidated balance sheets,

  The Company’s qualified defined benefit pension plans had an 
accumulated benefit obligation in excess of plan assets at Dec. 31, 
2004.  The  plans’  aggregate  accumulated  benefit  obligation  was 
$209 million, $192 million and $172 million at Dec. 31, 2004, 2003 
and 2002, respectively, and the fair value of plan assets was $186.8 
million, $168.3 million and $143.2 million, respectively. The fair 
value of plan assets increased from Dec. 31, 2003 to Dec. 31, 2004 
due to $22.5 million in investment gains and employer contribu-
tions of $8.3 million, partially offset by $11.2 million in withdraw-
als to pay benefits and $1.1 million to pay eligible expenses of the 
plans. The combination of investment returns and cash contribu-
tions  is  expected  to  provide  sufficient  funds  to  cover  all  benefit 
obligations of the plans. The Company is not required to make a 
cash contribution to either of its qualified pension plans for the 
2005 plan year.
  The Company’s investment policy and performance objectives 
for the qualified pension plan assets (plan assets) held in the Retire-
ment Trust Fund was approved by the retirement committee which 
is composed of management employees. The policy sets forth the 
guidelines and objectives governing the investment of plan assets. 
Plan assets are invested for total return with appropriate consider-
ation for liquidity and portfolio risk. All investments are expected 
to satisfy the requirements of the rule of prudent investments as 
set forth under the Employee Retirement Income Security Act of 
1974 (ERISA). The approved asset classes are cash and short-term 
investments, fixed income, common stock and convertible securi-
ties, absolute and real return strategies, real estate and investments 
in securities of NW Natural, and may be invested in separately 
managed accounts or in commingled or mutual funds. Re-balanc-
ing will take place at least annually, or when significant cash flows 
occur, in order to maintain the allocation of assets within the stated 

target allocation ranges. The Retirement Trust Fund is not currently 
invested in any NW Natural securities.
  The Company’s pension plan asset allocation at Dec. 31, 2004 
and 2003, and the target allocation and expected long-term rate of 
return by asset category for 2005 are as follows:

  The Company’s non-qualified supplemental pension plans’ ac-
cumulated  benefit  obligations  were  $13.6  million,  $13.0  million 
and $12.8 million at Dec. 31, 2004, 2003 and 2002, respectively. 
Although the plans are unfunded plans with no plan assets due to 
their nature as non-qualified plans, the Company indirectly funds 
its obligations with trust-owned life insurance.
  The  Company’s  plans  for  providing  postretirement  benefits 
other than pensions also are unfunded plans. The aggregate ben-
efit obligation for those plans was $22.7 million, $23.4 million and 
$18.5 million at Dec. 31, 2004, 2003 and 2002, respectively.
  The following tables provide the components of net periodic 
benefit cost for the qualified and non-qualified pension and other 
postretirement benefit plans for the years ended Dec. 31, 2004, 2003 
and 2002, and the assumptions used in measuring these costs and 
benefit obligations:

Notes to Consolidated Financial Statements

  The assumed annual increase in trend rates used in measuring 
postretirement  benefits  as  of  Dec.  31,  2004  were  10 percent  for 
medical and 13 percent for prescription drugs. Medical costs were 
assumed to decrease gradually each year to a rate of 4.5 percent 
for 2012, while prescription drug costs were assumed to decrease 
gradually each year to a rate of 4.5 percent for 2013.
  Assumed health care cost trend rates have a significant effect 
on the amounts reported for the health care plans. A one percent-
age point change in assumed health care cost trend rates would

  NW Natural’s Retirement K Savings Plan (RKSP) is a qualified 
defined  contribution  plan  under  Internal  Revenue  Code  Section 
401(k). NW Natural also has non-qualified deferred compensation 
plans for eligible officers and senior managers. These plans are de-
signed to enhance the retirement program of employees and to as-
sist them in strengthening their financial security by providing an 
incentive to save and invest regularly. NW Natural’s matching con-
tributions to these plans totaled $1.7 million in 2004, $1.6 million 
in 2003 and $1.4 million in 2002. Effective Jan. 1, 2002, the RKSP 
was  amended  to  establish  an  Employee  Stock  Ownership  Plan 
(ESOP) within the RKSP by converting the existing RKSP Company 
Stock Fund into an ESOP.
  Effective Jan. 1, 2005, the Company will make a contribution of 
25 cents per compensable hour on behalf of each union employee 
to the Western States Office and Professional Employees Pension 
Fund, which contributions will increase 3 percent each year, up to 
30 cents per compensable hour.

  The amount of income taxes paid in 2004 and 2003 decreased 
significantly as compared to the total provision for income taxes, 
primarily due to the effects of accelerated depreciation provisions 
provided by the Job Creation and Worker Assistance Act of 2002 
(the Assistance Act) and the Jobs and Growth Tax Relief Recon-
ciliation Act of 2003 (the Reconciliation Act). The Assistance Act 
provided for an additional depreciation deduction equal to 30 per-
cent of an asset’s adjusted basis. The Reconciliation Act increased 
this first-year additional depreciation deduction to 50 percent of an 
asset’s adjusted basis. The additional first-year depreciation deduc-
tion is an acceleration of depreciation deductions that otherwise 
would have been taken in the later years of an asset’s recovery pe-
riod. The accelerated depreciation provisions provided by both the 
Assistance Act and the Reconciliation Act expired at Dec. 31, 2004. 
The Company realized enhanced cash flow from reduced income 
taxes totaling an estimated $55 million during the effective period, 
based on plant investments made between Sept. 11, 2001 and Dec. 
31, 2004.
  For the year ended Dec. 31, 2004, the Company had an estimated 
federal net operating loss (NOL) of $15.4 million and an Oregon 
NOL of $18.6 million, primarily due to the effects of accelerated 
tax depreciation provided by the Assistance Act and the Reconcil-
iation Act. The federal NOL will be carried back to 2002 for a re-
fund of taxes paid in prior years, and the Oregon NOL will be used 
to reduce future Oregon taxable income. The Oregon NOL will ex-
pire in 2019.
  At Dec. 31, 2004 the Company had $1.6 million of alternative 
minimum tax credit carryforwards to offset regular federal income 
tax payable in future years. In addition, the Company had certain 
tax credits of approximately $0.7 million which are available to re-
duce certain federal and state income tax liabilities through 2011. 
The Company anticipates that it will be able to utilize all loss and 
credit carryforwards in future years.

  A Financial Corporation subsidiary, KB Pipeline Company (KB 
Pipeline), owns a 10 percent interest in an 18-mile interstate natu-
ral gas pipeline. KB Pipeline operated the pipeline for twelve years 
until Dec. 1, 2004, when a third party gas distribution company 
became the operator. KB Pipeline resigned as pipeline operator due, 
in part, to increased obligations resulting from final Federal Energy 
Regulatory  Commission  regulations  implementing  Standards  of 
Conduct for Transmission Providers. Those regulations govern the 
relationship between interstate natural gas pipelines and their en-
ergy affiliates or marketing functions and impose obligations pre-
viously inapplicable to KB Pipeline with regard to separation of 
duties and related matters. FERC granted KB Pipeline an exemp-
tion from most of the requirements of the Standards of Conduct; 
however, the remainder of the regulations continue to be applicable 
to KB Pipeline as a co-owner of the pipeline.
  At Dec. 31, 2004, Financial Corporation held ownership inter-
ests ranging from 4.0 to 5.3 percent in three solar electric genera-
tion plants located near Barstow, California. Power generated by 
these plants is sold to Southern California Edison Company under 
long-term contracts. Financial Corporation also has ownership in-
terests ranging from 25 to 41 percent in wind power electric gen-
eration projects located near Livermore and Palm Springs, Califor-
nia. The wind-generated power is sold to Pacific Gas and Electric 
Company and Southern California Edison Company under long-
term contracts. Financial Corporation sold its interests in the solar 
electric generation plants on Jan. 31, 2005 (see Note 2).

Notes to Consolidated Financial Statements

  FASB Interpretation No. 46, “Consolidation of Variable Interest 
Entities,” provides guidance for determining whether consolidation 
is  required  for  entities  over  which  control  is  achieved  through 
means other than voting rights, known as “variable interest enti-
ties.” The Company does not have any significant interests in vari-
able interest entities for which it is a primary beneficiary.

10.  FAIR VALUE OF FINANCIAL INSTRUMENTS:
  The estimated fair value of NW Natural’s financial instruments 
has been determined using available market information and appro-
priate valuation methodologies. The following are financial instru-
ments whose carrying values are sensitive to market conditions:

  amount due within one year  $  499,027  $  567,926  $  500,319  $  562,688

  Fair value of the long-term debt was estimated using market 
prices on the valuation date for debt with similar credit ratings, 
maturities, interest rates and other terms.

11.  USE OF FINANCIAL DERIVATIVES:
  NW Natural enters into short-term, medium-term and long-term 
natural gas purchase contracts with suppliers, including contracts 
tied to market-based index prices, and thus is exposed to changes 
in commodity prices. Natural gas prices are subject to fluctuations 
due to unpredictable factors including weather, inventory levels, 
pipeline  transportation  availability,  and  the  economy,  each  of 
which affects short-term supply and demand. As part of its overall 
strategy to maintain an acceptable level of exposure to gas price 
fluctuations, NW Natural uses a targeted mix of fixed-rate and cap-
protected derivative instruments to hedge the exposure under float-
ing price gas supply contracts. Swap contracts are used to convert 
certain  long-term  gas  purchase  contracts  from  floating  prices  to 
fixed prices. Call option contracts are used to limit the maximum 
adverse impact from floating price contracts while retaining the 
potential favorable impact from declining gas prices. The prices 
embedded in these commodity hedge contracts are incorporated 
in annual rate changes under the PGA rate mechanisms, thereby 
limiting customers’ exposure to frequent changes in purchased gas 
costs. The estimated fair value of gains and losses from commod-
ity hedge contracts are recorded as a derivative asset or liability, 
and are offset by a corresponding amount recorded to a deferred 
regulatory asset or liability account for the effective portion of each 
hedge contract. The actual gains and losses realized at settlement 
of the hedge contracts are used to offset the actual gas purchase 
cost from NW Natural’s physical supply contracts.
  Certain natural gas purchases from Canadian suppliers are in-
voiced in Canadian dollars, including both commodity and demand 
charges, thereby exposing NW Natural to adverse changes in for-
eign currency rates. Foreign currency forward contracts are used 
to minimize the impact of fluctuations in currency rates. Foreign 
currency contracts for commodity costs are purchased on a month-
to-month basis because the Canadian cost is priced at the average 
noonday exchange rate for each month. Foreign currency contracts 
for demand costs have terms ranging up to 24 months. The gains 
and losses on the shorter-term currency contracts for commodity 
costs  are  recognized  immediately  in  cost  of  gas.  The  gains  and 
losses on the longer-term currency contracts for demand charges 
are subject to a regulatory deferral tariff and, as such, are recorded 
as a derivative asset or liability which is offset by recording a cor-
responding amount to a deferred asset or liability account.

N W   N AT U R A L

  NW Natural did not use any derivative instruments to hedge oil 
or propane prices or interest rates during 2004, 2003 or 2002.
  At Dec. 31, 2004, NW Natural had the following derivatives out-
standing: a series of 24 fixed-price natural gas commodity price fi-
nancial swap contracts; four fixed-price natural gas financial call 
option contracts; and 62 foreign currency forward purchase con-
tracts. All of these contracts were designated as cash flow hedges 
covering exposures to commodity purchase and sale contracts. Un-
realized gains and losses from mark-to-market valuations of these 
contracts are not recognized in current income but are reported as 
derivative  assets  or  liabilities  and  offset  by  a  corresponding  de-
ferred account balance under regulatory liabilities or regulatory as-
sets because regulatory mechanisms include the realized gains or 
losses at settlement in utility gas costs subject to regulatory defer-
ral treatment. NW Natural also had outstanding at Dec. 31, 2004 
two natural gas physical supply contracts with embedded options 
which did not qualify as a normal purchase or normal sale. The 
physical supply contracts were entered into using excess gas stor-
age and pipeline transportation capacity under the Company’s op-
timization program. The estimated fair values (unrealized gains 
and losses) and the notional amounts of derivative instruments 
outstanding were as follows:

In 2004 and 2003, NW Natural realized net gains of $42.4 mil-
lion and $32.4 million, respectively, from the settlement of natural 
gas commodity swap and call option contracts, which were re-
corded as decreases to the cost of gas, compared to net losses of 
$75.5 million during 2002, which were recorded as increases to 
the cost of gas. The currency exchange rate in all foreign currency 
forward purchase contracts is included in NW Natural’s cost of 
gas at settlement; therefore, no gain or loss was recorded from the 
settlement of those contracts. Any change in value of cash flow 
hedge contracts that is not included in regulatory recovery is in-
cluded in OCI.
  The fair value of derivative instruments at Dec. 31, 2004 and 
2003 (see table above) was determined using estimated or quoted 
market  prices  for  the  periods  covered  by  the  contracts.  Market 
prices for the natural gas commodity-price swap and call option 
contracts were obtained from external sources. NW Natural reviews 
these third-party valuations for reasonableness using fair value cal-
culations for other contracts with similar terms and conditions. The 
market prices for the foreign currency forward contracts were based 
on currency exchange rates quoted by The Bank of Canada.
  As of Dec. 31, 2004, five of the natural gas commodity price 
swap contracts extended beyond Dec. 31, 2005, and two extended 
beyond Oct. 31, 2006. None of the natural gas commodity call op-
tion contracts extends beyond March 31, 2005.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     
     
     
 
12.  COMMITMENTS AND CONTINGENCIES:
Lease Commitments
  The  Company  leases  land,  buildings  and  equipment  under 
agreements that expire in various years through 2018. Rental ex-
pense under operating leases was $4.5 million, $4.9 million and 
$4.8 million for the years ended Dec. 31, 2004, 2003 and 2002, re-
spectively. The table below reflects the future minimum lease pay-
ments due under non-cancelable leases at Dec. 31, 2004. Such pay-
ments  total  $60.8  million  for  operating  leases.  The  net  present 
value of payments on capital leases less imputed interest was $0.5 
million. These commitments principally relate to the lease of the 
Company’s office headquarters, underground gas storage facilities, 
vehicles and computer equipment.

Pipeline Capacity Purchase and Release Commitments
  NW Natural has signed agreements providing for the reserva-
tion  of  firm  pipeline  capacity  under  which  it  must  make  fixed 
monthly payments for contracted capacity. The pricing component 
of the monthly payment is established, subject to change, by U.S. 
or Canadian regulatory bodies. In addition, NW Natural has en-
tered into long-term sale agreements to release firm pipeline capac-
ity. The aggregate amounts of these agreements were as follows at 
Dec. 31, 2004:

  NW Natural’s total payments of fixed charges under capacity 
purchase agreements in 2004, 2003 and 2002 were $89.3 million, 
$86.7 million and $86.2 million, respectively. Included in the amounts 
for 2004, 2003 and 2002 were reductions for capacity release sales 
of $3.7 million, $3.7 million and $4.2 million, respectively. In ad-
dition, per-unit charges are required to be paid based on the actual 
quantities  shipped  under  the  agreements.  In  certain  take-or-pay 
purchase commitments, annual deficiencies may be offset by pre-
payments subject to recovery over a longer term if future purchases 
exceed the minimum annual requirements.
Environmental Matters
  NW Natural owns or previously owned properties currently be-
ing  investigated  that  may  require  environmental  response.  NW 
Natural has accrued all material loss contingencies relating to en-
vironmental matters that it believes to be probable of assertion and 
reasonably estimable. The Company continues to study the extent 
of its environmental liabilities, but due to the preliminary nature 
of the environmental investigations being conducted, the range of 
loss contingencies beyond the amounts currently accrued, and the 
probabilities thereof, cannot be reasonably estimated.

  GASCO SITE. NW Natural owns property in Multnomah County, 
Oregon that is the site of a former gas manufacturing plant that 
was closed in 1956 (the Gasco site). The Gasco site has been un-
der investigation by NW Natural for environmental contamination 
under the Oregon Department of Environmental Quality’s (ODEQ) 
Voluntary Clean-Up Program. In June 2003, the Company filed a 
Feasibility Scoping Plan and an Ecological and Human Health Risk 
Assessment with the ODEQ, which outlined a range of remedial 
alternatives for the most contaminated portion of the Gasco site. 
NW Natural continues to work with the ODEQ to determine the 
appropriate remedial action from among the alternatives. Based 
upon the proposed actions in the draft plan, the Company esti-
mates its range of remaining liability, including the cost of investi-
gation, from among feasible alternatives, at between $1.3 million 
and $7 million.
  WACKER SITE. NW Natural previously owned property adjacent 
to the Gasco site that now is the location of a manufacturing plant 
owned by Siltronic Corporation, formerly Wacker Siltronic Corpo-
ration (the Wacker site). In 2000, the ODEQ issued an order requir-
ing Wacker and NW Natural to determine the nature and extent of 
releases of hazardous substances to Willamette River sediments 
from the Wacker site. In 2004, consultant studies indicated that 
some benzene is present in the soil at the Wacker site. The ODEQ 
requested that NW Natural conduct further tests of groundwater 
and indoor air quality. The work plan for the implementation of 
the  benzene  indoor  air-sampling  program  was  approved  by  the 
ODEQ in November 2004. NW Natural recorded expenses in 2004 
totaling $0.1 million for its estimated costs of investigation and ini-
tial remediation at the Wacker site.

PORTLAND HARBOR. In 1998, the ODEQ and the U.S. Environ-
mental Protection Agency (EPA) completed a study of sediments 
in a 5.5-mile segment of the Willamette River (the Portland Har-
bor)  that  includes  the  area  adjacent  to  the  Gasco  site  and  the 
Wacker site. In 2000, the EPA listed the Portland Harbor as a Su-
perfund site and notified the Company that it is a potentially re-
sponsible party. Subsequently, the EPA approved the Programmatic 
Work Plan, Field Sampling Plan and Quality Assurance Project Plan 
for the Portland Harbor Remedial Investigation/Feasibility Study. 
NW Natural’s share of the estimated budget to complete the first 
phase of the work is $1.0 million, which is expected to be com-
pleted in 2007. The EPA has indicated that further study in a sec-
ond phase will be required; however, the scope of the work to be 
completed in a second phase has yet to be determined.

In April 2004 the Company entered into an Administrative Or-
der on Consent (AOC) providing for early action removal of a body 
of tar in the river sediments adjacent to the Gasco site. In July 2004, 
the EPA approved an initial work plan for the early action removal. 
The Company continues to negotiate with the EPA regarding the 
method and timing of the removal of the body of tar. The Company 
currently estimates the removal cost to be in the range of $3.0 mil-
lion to $5.0 million. In addition, the Company has agreed with the 
ODEQ to do additional work, if necessary, on the Gasco site in con-
junction with the EPA early action remediation work.

Notes to Consolidated Financial Statements

  During 2004, NW Natural accrued additional loss contingencies 
totaling $4.3 million for the above-described study work and the 
revised estimate of tar body remediation costs. NW Natural’s liabil-
ity is based on its best estimate of probable costs, and if a specific 
amount is no more or less likely than another amount in the range 
of probable liability, then the Company recognizes its liability at 
the lower end of the range of probable liability. Currently available 
information is insufficient to determine either the total amount of 
liability, or the higher end of a range for NW Natural’s estimated 
share of potential future remediation related to the Portland Harbor 
site. The Company expects to receive additional information when 
the Remedial Investigation/Feasibility Study report is completed. 
A preliminary report is expected to be available during 2005.

PORTLAND GAS SITE. The City of Portland notified NW Natural 
that it was planning a sewer improvement project that would in-
clude  excavation  within  the  former  site  of  a  gas  manufacturing 
plant (the Portland Gas site) that was owned and operated by a 
predecessor of the Company between 1860 and 1913. The prelimi-
nary assessment of this site performed by a consultant for the EPA 
in 1987 indicated that it could be assumed that by-product tars may 
have been disposed of on site. The report concluded, however, that 
it is likely that waste residues from the plant, if present on the site, 
were covered by deep fill during construction of the nearby seawall 
bordering the Willamette River and probably have stabilized due 
to physical and chemical processes. Neither the City of Portland nor 
the ODEQ has notified NW Natural whether a further investigation 
or potential remediation might be required on the site in connec-
tion with the sewer project, which has commenced. Available in-
formation is insufficient to determine either the total amount of NW 
Natural’s liability or a probable range, if any, of potential liability.
  OREGON STEEL MILLS SITE. On Dec. 20, 2004, the Company was 
served with a third-party complaint by the Port of Portland (Port) 
in a Multnomah County Circuit Court case, Oregon Steel Mills, Inc. 
v.  The  Port  of  Portland.  The  Port  alleges  that  in  the  1940’s  and 
1950’s petroleum wastes generated by the Company’s predecessor, 
Portland Gas & Coke Company, and nine other third-party defen-
dants were disposed of in a waste oil disposal facility operated by 
the United States or Shaver Transportation Company on property 
then owned by the Port and now owned by Oregon Steel Mills. The 
Port’s complaint seeks contribution for unspecified past remedial 
action costs incurred by the Port regarding the former waste oil dis-
posal facility as well as a declaratory judgment allocating liability 
for future remedial action costs. NW Natural does not believe there 
are facts sufficient to constitute a claim against the Company.

CORPS  OF  ENGINEERS  NOTICE  OF  NONCOMPLIANCE.  On  July  2, 
2004, the U.S. Army Corps of Engineers (Corps) issued to the Com-
pany a Notice of Noncompliance (Notice) for discharges of drilling 
mud into three streams during drilling operations on the Compa-
ny’s South Mist Pipeline Extension (SMPE) project. The Corps’ No-
tice claimed that the discharges violated the scope of work in per-
mits for the drilling. The Company cooperated with the Corps in 
its investigation and worked closely with the Corps and other state 
and federal agencies to minimize impacts from the unintended dis-
charges. The final disposition of this matter resulted in the payment 
of a nominal fine.

REGULATORY  AND  INSURANCE  RECOVERY  FOR  ENVIRONMENTAL 
MATTERS. In May 2003, the OPUC approved NW Natural’s request 
for deferral of environmental costs associated with specific sites, 
including the Gasco, Wacker, Portland Harbor and Portland Gas 
sites. The authorization, which has been extended through April 
2005, allows NW Natural to defer and seek recovery of unreim-
bursed environmental costs in a future general rate case. On a cu-
mulative basis through Dec. 31, 2004, the Company paid out a to-
tal of $3.3 million relating to the named sites since the effective 
date of the deferral authorization. NW Natural will first seek to re-
cover the costs of investigation and remediation for which it may 
be responsible with respect to the Gasco, Wacker, Portland Harbor 
and Portland Gas sites, if any, from insurance. If these costs are not 
recovered from insurance, then NW Natural will seek OPUC ap-
proval to recover them through future rates. At Dec. 31, 2004, NW 
Natural had a receivable of $8.5 million representing an estimate 
of the environmental costs it expects to recover from insurance, 
consisting of $2.8 million for costs relating to the Gasco site, $5.5 
million for costs relating to the Portland Harbor site and $0.2 mil-
lion relating to the Oregon Steel Mills site.
  On Jan. 27, 2005, NW Natural filed a request with the OPUC for 
authorization to defer costs associated with the Oregon Steel Mills 
site and to extend the deferral authority for the other named envi-
ronmental sites through Jan. 26, 2006.
  The following table summarizes the insurance receivables and 
the accrued liabilities relating to environmental matters at Dec. 31, 
2004 and 2003.

Legal Proceedings
Litigation
  On  October  16,  2003,  Longview  Fibre  Company  (Longview) 
filed suit in Federal Court (Longview Fibre Company v. Enerfin Re-
sources Northwest Limited Partnership and Northwest Natural Gas 
Company (US District Court – Oregon District)) seeking a declara-
tory judgment regarding the continuing existence of a certain oil 
and gas lease in the Mist gas field between Longview and Enerfin 
Resources Northwest Limited Partnership (Enerfin). NW Natural 
holds  a  gas  storage  lease  from  Longview  (the  Cascade  Lease), 
which covers the same land as the Enerfin lease, and which grants 
the  right  to  produce  native  oil  and  gas.  Enerfin  originally  filed 
crossclaims against NW Natural alleging that NW Natural wrongly 
interfered with Enerfin’s attempts to continue its oil and gas lease 
with Longview; however, Enerfin agreed to dismiss those claims 
in a previous settlement with NW Natural. In that settlement, NW 
Natural subleased portions of the Cascade Lease to Enerfin for the 
purpose of producing native gas. In September 2004, NW Natural 
and Enerfin filed claims and counterclaims against Longview, and 
Longview filed claims and counterclaims against NW Natural and 
Enerfin. The claims that Longview made against NW Natural in-
volved allegations of unpaid royalties under the Cascade Lease.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     
     
     
  On Dec. 20, 2004, the Company was served with a third-party 
complaint by the Port of Portland (Port) in a Multnomah County 
Circuit Court case, Oregon Steel Mills, Inc. v. The Port of Portland. 
The Port alleges that in the 1940’s and 1950’s petroleum wastes 
generated  by  the  Company’s  predecessor,  Portland  Gas  &  Coke 
Company, and nine other third-party defendants were disposed of 
in  a  waste  oil  disposal  facility  operated  by  the  United  States  or 
Shaver Transportation Company on property then owned by the 
Port and now owned by Oregon Steel Mills. The Port’s complaint 
seeks contribution for unspecified past remedial action costs in-
curred by the Port regarding the former waste oil disposal facility 
as well as a declaratory judgment allocating liability for future re-
medial action costs. NW Natural does not believe there are facts 
sufficient to constitute a claim against the Company.

In connection with the construction of the SMPE, NW Natural 
continues to negotiate with some land owners regarding valuation 
of easements and rights-of-way obtained pursuant to condemna-
tion proceedings. In some cases, compensation will be determined 
in individual court proceedings that have been scheduled through 
June 2005. The Company is unable to determine the likelihood of 
unfavorable outcomes of these matters, but believes that the ag-
gregate amount of compensation ultimately paid will not be mate-
rial to the Company’s financial condition, results of operations or 
cash flows.
  The Company is subject to other claims and litigation arising in 
the ordinary course of business. Although the final outcome of any 
of these legal proceedings cannot be predicted with certainty, the 
Company does not expect that the ultimate disposition of these 
matters will have a materially adverse effect on the Company’s fi-
nancial condition, results of operations or cash flows.

  All parties to the Longview litigation entered into a Settlement 
Agreement,  effective  Jan.  11,  2005.  As  part  of  the  settlement, 
Longview granted NW Natural an easement for use in producing 
oil and gas from the lands covered by the Cascade Lease. Other 
than payments made in respect of the easement, and royalty pay-
ments under the relevant leases and subleases, which were not 
material, no payments were made in connection with the Longview 
settlement. All claims were dismissed on Jan. 28, 2005 pursuant to 
the Settlement Agreement.
  On  May  28,  2004,  a  lawsuit  was  filed  against  the  Company 
(Kerry Law, Arnold Zuehlke and Kenneth Cooper, on behalf of them-
selves and all others similarly situated v. Northwest Natural Gas 
Company (U.S. Dist. Ct. D. Or., Case No. CV-04-728-AS)) by three 
individuals alleging violation of the Fair Labor Standards Act for 
failure to pay overtime. The suit was subsequently amended to in-
clude state wage and hour claims. The plaintiffs are or have been 
independent  backhoe  operators  who  performed  services  for  the 
Company under contract. In the lawsuit, the plaintiffs claim that 
they, and others similarly situated, should have been considered 
“employees” of the Company instead of independent contractors. 
The plaintiffs seek overtime and interest in amounts to be deter-
mined, liquidated damages equal to the overtime award, civil pen-
alties and attorneys fees and costs. The plaintiffs sought to certify 
this case as a collective action under the Fair Labor Standards Act; 
however, on Oct. 5, 2004, plaintiffs’ motion for collective action 
certification was denied. As a result of this ruling, the case is pro-
ceeding with the three current plaintiffs, and any others who wish 
to  join  must  do  so  individually.  Although  no  other  claims  have 
been filed in this lawsuit, plaintiffs’ counsel has indicated to the 
court their intention to file additional claims seeking employee ben-
efits allegedly due to plaintiffs. In addition, the claims in the law-
suit described below may be consolidated with this lawsuit. The 
Company intends to vigorously contest the claims. There is insuf-
ficient information at this point in the litigation to reasonably esti-
mate the amount of liability, if any, from this claim.
  On  Feb.  18,  2005,  a  lawsuit  was  filed  against  the  Company 
(Kasey Cooper, Kevin Cooper, C.G. Nick Courtney, John V. Shooter, 
Ike Whittlesey and Roger Whittlesey v. Northwest Natural (U.S. Dist. 
Ct. D. Or., Case No. CV-05-241-KI)) by six additional individual in-
dependent backhoe operators who have performed services for the 
Company under contract. Like the plaintiffs in the claim described 
above, these plaintiffs allege that they should have been considered 
“employees” of the Company. They seek overtime wages under the 
Fair Labor Standards Act and interest in amounts to be determined, 
liquidated damages equal to the overtime award, civil penalties and 
attorneys fees and costs. In addition, the plaintiffs allege that fail-
ure to classify them as employees constituted a breach of contract 
under certain of the Company’s employee benefit programs, agree-
ments and plans, which conferred employment-related compensa-
tion, rights and benefits. They seek an unspecified amount of dam-
ages for the value of what they would have received under these 
programs, agreements and plans if they had been classified as em-
ployees. The Company intends to vigorously contest the claims. 
There is insufficient information at this point in the litigation to rea-
sonably estimate the amount of liability, if any, from this claim.

*Quarterly earnings per share are based upon the average number of common shares outstanding 
during each quarter. Because the average number of shares outstanding has changed in each  
quarter shown, the sum of quarterly earnings may not equal earnings per share for the year.  
Variations in earnings between quarterly periods are due primarily to the seasonal nature of  
the Company’s business.
