                          NORTHWEST NATURAL GAS COMPANY
                          PART I. FINANCIAL INFORMATION
                 (6) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   Basis of Financial Statements

          The information presented in the consolidated financial statements is
unaudited, but includes all adjustments, consisting of only normal recurring
accruals, which the management of the Company considers necessary for a fair
presentation of the results of such periods. These consolidated financial
statements should be read in conjunction with the financial statements and
related notes included in the Company's 2000 Annual Report on Form 10-K, as
amended (2000 Form 10-K). A significant part of the business of the Company is
of a seasonal nature; therefore, results of operations for the interim periods
are not necessarily indicative of the results for a full year.

          Certain amounts from prior periods have been reclassified to conform
with the 2001 presentation. These reclassifications had no impact on prior
period results of operations.

2.   Revenue Recognition

          The Company's utility revenues are derived primarily from the sale and
transportation of natural gas. The Company recognizes utility revenue from gas
sales and transportation when the gas is delivered to customers. Estimated
revenues are accrued for gas deliveries not billed to customers from meter
reading dates to month end (unbilled revenue) and are reversed in the following
month when actual billings occur.

          Revenues from non-utility services, including gas storage services,
are recognized upon delivery of the service to customers. Guaranteed minimum
obligations for gas storage services are recognized over the term of the
contract.

3.   Derivatives Policy

          NW Natural's Derivatives Policy allows the use of selected financial
derivative products to support prudent risk management strategies within
designated parameters for natural gas commodity prices, for foreign currency
exchange rates related to the Company's natural gas purchase commitments, for
oil or propane commodity prices related to natural gas sales or transportation
under rate schedules pegged to commodities other than natural gas, and for
interest rates on outstanding long-term debt instruments maturing in less than
five years. The objective is to use derivative products to structure "hedge"
positions as defined by the policy. Use of derivatives is permitted only after
the purchase price, exchange rate, oil or propane index price, and interest rate
exposures that have been identified are determined to exceed defined tolerance
levels and are considered to be unavoidable because they are necessary or
support normal business activities.

          The Derivatives Policy is intended to decrease the Company's net
exposures to commodity price, exchange rate and interest rate risks (market
risks) by using hedging strategies and derivative structures within certain
limitations. The policy is intended to prevent speculative risk. The Company
believes that any increase in market risk created by the use of the derivatives
should be offset by the exposures they modify.

4.   New Accounting Standards

          In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities." This statement establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts and for hedge accounting. It
requires that an entity measure all derivatives at fair value and recognize
those derivatives as either assets or liabilities on the balance sheet. If the
derivative is designated as a fair value hedge, the net changes in the fair
value of the derivative and of the hedged item attributable to the hedged risk
are recognized in current earnings. If the derivative is designated as a cash
flow hedge, the effective portions of changes in the fair value of the
derivative are recorded in other comprehensive income (OCI), or in deferred
asset accounts for regulated activities (see Note 5, below), and recognized in
the income statement when the hedged item affects earnings. Ineffective portions
of changes in the fair value of cash flow hedges are recognized in current
earnings. Some of the Company's gas purchase, sales and transportation contracts
are derivative instruments as defined under SFAS No. 133.

          In June 2000, the FASB issued SFAS No. 138, "Accounting for Certain
Derivative Instruments and Certain Hedging Activities," amending portions of
SFAS No. 133. Among other things, SFAS No. 138 provides an exception for
contracts intended for the normal purchase and normal sale of something other
than a financial instrument or derivative instrument, for which physical
delivery is probable.

5.   Adoption of New Accounting Standard

          The Company adopted SFAS No. 133, as amended, on Jan. 1, 2001. The
Company's primary derivatives hedging activities are being accounted for as cash
flow hedges under this statement. Unrealized gains or losses resulting from
mark-to-market valuations of the underlying hedge contracts are subject to
deferral under the Company's tariffs with the Oregon Public Utility Commission
(OPUC) and the Washington Utilities and Transportation Commission (WUTC).
Pursuant to SFAS No. 71, "Accounting for the Effects of Certain Types of
Regulation," contracts representing unrealized gain or loss positions are
reported as derivative assets or liabilities and are offset by a corresponding
deferred account included under "Regulatory Assets" or "Regulatory Liabilities."
Due to their regulatory deferral treatment, effective portions of changes in the
fair value of these derivatives are not recorded in OCI, but are deferred as a
regulatory asset or liability. Effectiveness is measured by comparing changes in
cash flows of the hedged item to gains or losses on derivative instruments.

          The Company formally documents all relationships between hedging
contracts and hedged items, as well as its risk management objective and
strategy for undertaking the hedge. This process includes specific
identification of the hedging contract and the hedge transaction, the nature of
the risk being hedged and how the hedging instrument's effectiveness will be
measured. Both at the inception of the hedge and on an ongoing basis, the
Company measures effectiveness of the derivatives used in hedging transactions.

          NW Natural enters into short-term and long-term natural gas purchase
contracts with demand and commodity fixed-price and variable-price components,
along with associated short-term and long-term natural gas transportation
contracts. The prices of natural gas commodity are subject to fluctuations due
to unpredictable factors including weather, pipeline transportation congestion
and the economy, each of which affects short-term supply and demand. NW Natural
uses natural gas commodity swap and cap agreements to convert certain of its
long-term purchase contracts from floating prices to fixed prices.


                                       10



          Many of the purchases made under these gas purchase contracts are
priced in Canadian dollars. The costs of natural gas commodity and pipeline
services purchased from certain Canadian suppliers are subject to changes in the
value of Canadian currency in relation to U.S. currency. NW Natural uses foreign
currency forward contracts to hedge against fluctuations in currency exchange
rates with respect to its purchases of natural gas from suppliers in Canada.

          The adoption of SFAS No. 133 effective Jan. 1, 2001 resulted in the
Company recording a one-time transition adjustment by debiting a derivative
asset account and crediting an offsetting regulatory asset account on the
balance sheet for approximately $165 million. This transition adjustment
represented the initial recognition of the fair values of hedge derivatives
outstanding on the adoption date.

          At June 30, 2001, the Company had two types of natural gas commodity
cash flow hedges open: a series of 17 natural gas price swap agreements and four
call option agreements. The net decrease in the fair value of these hedge
derivatives for the six months ended June 30, 2001 ($241.5 million), included
net gains of $86.9 million realized as reductions to the cost of gas upon
settlement of various cash flow hedges. During the six months ended June 30,
2001, the amount of hedge ineffectiveness recognized in earnings from
derivatives that are designated and qualify as cash flow hedges was negligible.
All remaining outstanding derivative instruments in these categories at June 30,
2001, were determined to be 100 percent effective (see Part I, Item 2., "Results
of Operations - Cost of Gas," below).

          The estimated fair values for these derivative hedge instruments at
Jan. 1 and June 30, 2001 are presented below:

                                                         Jan. 1,      June 30,

          The fair value of fixed-price contracts as of June 30, 2001 was
estimated based on market prices for the periods covered by the contracts. The
net differential between the prices in each contract and market prices for
future periods, as adjusted for estimated basis, where applicable, has been
applied to the volumes stipulated in each contract to arrive at an estimated
future value. As of June 30, 2001, a total of nine natural gas price swap
agreements have contract periods that extend beyond Dec. 31, 2001. As of June
30, 2001, the Company had not entered into any natural gas call option contracts
extending beyond Dec. 31, 2001.

          The Company recorded a $0.1 million loss for the first six months of
2001, representing the change in value of an embedded derivative relating to a
contract for an equipment financing program under which NW Natural guarantees a
minimum level of return for the lender.

          The Derivatives Implementation Group (DIG), a group sponsored by the
FASB, continues to develop interpretive guidance relating to SFAS No. 133.


                                       11



Future interpretations of SFAS No. 133 by the DIG or the FASB could impact the
Company's application of the standard and, thereby, its financial statement
disclosures.

6.   Segment Reporting

          The Company principally operates in a segment of business consisting
of the distribution of natural gas ("Utility"). Another segment, which was
immaterial prior to Jan. 1, 2001, represents natural gas storage services
provided to upstream customers using storage capacity not required from time to
time for service to utility customers ("Gas Storage"). The remaining segment
primarily consists of non-regulated investments in alternative energy projects
in California, the oil and gas exploration properties sold in 2000 and a Boeing
737-300 aircraft which is leased to Continental Airlines ("Other").

          The following table presents information about the reportable segments

7.   Property Held for Sale

          Property held for sale at June 30, 2000 consisted of a new
headquarters building that was constructed for the Port of Portland. This
property was sold during the third quarter of 2000 (see Part II, Item 7.,
"Financial Condition - Cash Flows - Port of Portland Building," in the 2000 Form
10-K).


                                       12



8.   Discontinued Segment

          On Jan. 26, 2000, the Company sold its interest in Canor Energy, Ltd.
(Canor), an Alberta, Canada corporation engaged in natural gas and oil
exploration, development and production in Alberta and Saskatchewan, Canada. As
of March 31, 2000, the Company realized an after-tax gain from the sale of Canor
of $2.4 million, net of Canadian tax on dividends ($0.6 million) and U.S. income
tax ($2.8 million) (see Part II, Item 8., Note 2, "Canor Energy, Ltd.," in the
2000 Form 10-K).

          Proceeds from the sale of Canor are reflected in the statement of cash
flows (Investing Activities) as proceeds from sale of discontinued segment.

9.   Contingencies

          Environmental Matters
          ---------------------

          The Company owns property in Linnton, Oregon that is the site of a
former gas manufacturing plant that was closed in 1956 (the Linnton site). The
Company previously owned property adjacent to the Linnton site that now is the
location of a manufacturing plant owned by Wacker Siltronic Corporation (the
Wacker site). The Linnton site and the Wacker site have been under investigation
by the Company under program oversight by the Oregon Department of Environmental
Quality (ODEQ). In 1998, the ODEQ and the U.S. Environmental Protection Agency
(EPA) completed a study of sediments in a 5.5 mile segment of the Willamette
River (the Portland Harbor) that includes the area adjacent to the Linnton site
and the Wacker site. In 2000, the EPA listed the Portland Harbor as a Superfund
site. See Part II, Item 8., Note 12, "Notes to Consolidated Financial
Statements," in the 2000 Form 10-K.

          NW Natural has accrued all material loss contingencies which it
believes to be probable of assertion, including those relating to the Linnton
site, the Wacker site and the Portland Harbor Superfund site. However, due to
the preliminary nature of these environmental investigations, the range of any
additional possible loss cannot be presently estimated. The Company expects that
its costs of investigation and any remediation for which it may be responsible
with respect to the Linnton site, the Wacker site and the Portland Harbor
Superfund site should be recoverable, in large part, from insurance. In the
event these costs are not recovered from insurance, NW Natural will seek
recovery through future rates.

          Litigation
          ----------

          NW Natural is party to a lawsuit, Northwest Natural Gas Company v.
Chase Gardens, Inc. (Lane County Circuit Court Case No. 16-91-01370), involving
claims by a commercial customer. In 1999, the Oregon Supreme Court ruled in the
Company's favor on the larger of the two claims in the case and the Oregon Court
of Appeals ruled in the Company's favor on the smaller (contract) claims. The
Oregon Supreme Court initially declined to review the Court of Appeals' decision
on the contract claims, including a verdict against the Company in the amount of
$2.0 million plus interest. On reconsideration, however, in December 2000 the
Supreme Court agreed to review the Court of Appeals' decision on the contract
claims and is expected to issue an opinion in 2001. See Part I, Item 3., "Legal
Proceedings," in the 2000 Form 10-K.

Item 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS
          AND FINANCIAL CONDITION

        The consolidated financial statements include:

        Regulated utility:
          Northwest Natural Gas Company (NW Natural)
        Non-regulated subsidiary businesses:
          NNG Financial Corporation (Financial Corporation), a wholly-owned
            subsidiary
          Canor Energy, Ltd. (Canor), a majority-owned subsidiary, reclassified
            as a discontinued segment and sold in the first quarter of 2000

          Together these businesses are referred to herein as the "Company" (see
"Non-utility Operations," below, and Part II, Item 8., Note 2, "Notes to
Consolidated Financial Statements," in the Company's 2000 Annual Report on Form
10-K, as amended (2000 Form 10-K)).

          The following is management's assessment of the Company's financial
condition including the principal factors that affect results of operations. The
discussion refers to the consolidated activities of the Company for the three
and six months ended June 30, 2001 and 2000.

Earnings and Dividends
- ----------------------

          The Company's earnings applicable to common stock were $4.3 million or
17 cents a diluted share in the quarter ended June 30, 2001, up from $1.8
million or 7 cents a diluted share in the second quarter of 2000.

          NW Natural earned 14 cents a diluted share from gas utility operations
in the second quarter of 2001, compared to 9 cents in the same period in 2000.
Weather conditions in its service territory in the second quarter of 2001 were
19 percent colder than the 20-year average and 29 percent colder than the second
quarter of 2000. Sales to residential customers were 12 percent higher in the
second quarter of 2001 than in the second quarter of 2000. However, reflecting
the effect of recent tracking rate increases to recover higher gas costs (see
"Results of Operations - Comparison of Gas Operations - Residential and
Commercial," below), residential customers' consumptions per heating degree day
were about 10 percent lower during the second quarter of 2001 than in the second
quarter of 2000. Sales to commercial customers were 9 percent higher in the
second quarter of 2001 than in the second quarter of 2000, but their
consumptions per heating degree day were about 11 percent lower.

          The Company earned $29.6 million, or $1.16 a diluted share, and $32.9
million, or $1.29 a diluted share, for the six months ended June 30, 2001 and
2000, respectively. Year-to-date, NW Natural earned $1.10 a share from utility
operations compared to $1.20 a share in the same period in 2000. Weather in the
first half of the year was 8 percent colder than the 20-year average and 3.5
percent colder than in 2000. Residential customers' consumptions per heating
degree day were about 9 percent lower during the first six months of 2001 than
in the first half of 2000, while commercial customers' consumptions were about
8.5 percent lower.

          Non-utility operating results for the second quarter of 2001 were
earnings of 3 cents a share compared to a loss of 2 cents a share from these
operations in 2000. Non-utility operating results year-to-date were earnings of
6 cents a share compared to a loss of 1 cent a share from these operations
during the comparable period in 2000. See "Non-utility Operations," below.


                                       14



          Dividends paid on common stock were 31 cents a share for each of the
three-month periods ended June 30, 2001 and 2000. In July 2001, the Company's
Board of Directors declared a quarterly dividend of 31 cents a share on the
common stock, payable Aug. 15, 2001, to shareholders of record on July 31, 2001.
The current indicated annual dividend rate is $1.24 a share.

          Residential and Commercial
          --------------------------

          NW Natural continues to experience rapid customer growth, with 19,807
customers added since June 30, 2000, for a growth rate of 3.9 percent. In the
three years ended Dec. 31, 2000, more than 65,000 customers were added to the
system, representing an average annual growth rate of 4.6 percent.

          Typically, 75 percent or more of NW Natural's annual operating
revenues are derived from gas sales to weather-sensitive residential and
commercial customers. Accordingly, variations in temperatures between periods
will affect volumes of gas sold to these customers. Average weather conditions
are calculated from the most recent 20 years of temperature data measured by
heating degree-days. Weather conditions in the second quarter of 2001 were 19
percent colder than average and 29 percent colder than in the second quarter of
2000. For the first six months of 2001, weather was 8 percent colder than
average and 3.5 percent colder than in the first six months of 2000.

          Volumes of gas sold to residential and commercial customers increased
11.2 million therms, or 12 percent, in the second quarter of 2001 compared to
the second quarter of 2000. Related revenues increased $23.5 million, or 34
percent, due to the higher volumes of gas sold and to rate increases averaging
23 percent during 2000. (See Part II, Item 7, "Results of Operations -
Regulatory Matters," in the 2000 Form 10-K.) Customer growth in the residential
and commercial segments since June 30, 2000 contributed an estimated 3 million
therms in sales volumes and $1.4 million in additional margin during the first
six months of 2001.

          NW Natural believes the recent reductions in its customers' gas
consumptions per degree day (see "Earnings and Dividends," above) are caused by
the Company's much higher cost of purchased gas, which NW Natural passed through
to customers as rate increases last fall, and to efforts throughout the region
to conserve energy. NW Natural has filed with the Oregon Public Utility
Commission (OPUC) for approval of a new regulatory mechanism that is intended to
stabilize margin revenues in the face of variable consumption patterns. If
approved, this mechanism would increase margin revenues during periods when
residential and commercial customers' consumptions are less than the average
assumed in the Company's 1998 general rate case. Conversely, margin revenues
would be reduced when consumptions were higher than the average. The mechanism
also would allow the Company to be more proactive in encouraging customers'
efforts to use energy efficiently in their homes and businesses and to manage
their energy bills. The Company's goal is to have such a mechanism in place
before the next heating season starts in October, thereby reducing future
earnings volatility.

          Industrial, Transportation and Other Revenues
          ---------------------------------------------

          Total volumes delivered to industrial firm, industrial interruptible,
and transportation customers were 11 percent lower in the second quarter of 2001
than in the same period of 2000. Margin from these customers decreased from
$10.8 million in the second quarter of 2000 to $10.3 million in the second
quarter of 2001. The primary factor contributing to this decrease was a $0.5
million decrease in margin from customers who used oil during this period
because the cost of oil was lower than the cost of natural gas purchased on the
spot market.

          Besides its core market, another developing market for NW Natural is
the delivery of natural gas for use in the generation of electricity. A number
of generation projects are being developed in the Company's service area in
order to help meet the demand for power in the western United States. NW Natural
commenced gas deliveries in July 2001 to Clark Public Utility District (Clark
PUD) in Vancouver, Washington, for a one-year term of service. Clark PUD will
use the gas to produce up to 50 megawatts of electricity.


                                       16



          Other revenues include amortizations from regulatory accounts and
miscellaneous fees charged to gas sales customers (see Part II, Item 8., Note 1,
"Notes to Consolidated Financial Statements," in the 2000 Form 10-K). Other
revenues increased $0.1 million during the second quarter of 2001 compared to
the second quarter of 2000. Year-to-date, other revenues increased $0.3 million
compared to the first six months of 2000. Factors contributing to the increase
in the first six months of 2001 were higher amortizations from regulatory
accounts covering conservation programs ($2.6 million), partially offset by
higher property tax amortizations ($1.7 million) and higher revenues from
customer late payment and reconnection fees ($1.1 million).

          Cost of Gas
          -----------

          The cost per therm of gas sold was 34 percent higher during the second
quarter of 2001 than in the second quarter of 2000, primarily due to higher
prices in the natural gas commodity market. The cost of gas sold includes
current gas purchases, gas drawn from storage inventory, gains or losses from
commodity hedges, demand cost equalization, regulatory deferrals and company
use.

          Results for the three months ended June 30, 2001 include an adjustment
reducing the cost of gas and a partially offsetting adjustment reducing interest
income (see "Other Income (Expense)," below). These adjustments were based on a
clarification of the treatment of gas storage inventory, approved by the OPUC
effective June 30, 2001, under NW Natural's Purchased Gas Adjustment (PGA)
mechanism in Oregon. Excluding this adjustment ($3.0 million), the cost per
therm of gas sold was 41 percent higher during the second quarter of 2001 than
in the second quarter of 2000 and was 40 percent higher year-to-date. Of the
total adjustment to the cost of gas, $1.6 million applied to deferrals in the
first and second quarters of 2001 and $1.4 million applied to a prior period
from Dec. 1, 1999 through Dec. 31, 2000. Under an agreement between the Company
and the OPUC staff, the methodology applied in this adjustment to cost of gas
will continue to be applied in the future.

          NW Natural offset some of the impact of its higher gas costs during
the second quarter of 2001 through an active natural gas commodity hedge program
conducted under the terms of the Company's Derivatives Policy (see Item 1, Note
3., "Notes to Consolidated Financial Statements," above). NW Natural recorded
net gains from commodity swap and call option contracts of $13.4 million in the
second quarter of 2001, compared to net gains of $4.1 million in the second
quarter of 2000. Year-to-date, NW Natural recorded net gains of $86.9 million,
compared to net gains of $3.2 million during the first six months of 2000. Gains
(losses) from commodity hedges are recorded as reductions (increases) to the
cost of gas. The cost of gas sold also was reduced by off-system gas sales of
$1.2 million and $1.4 million for the first six months of 2001 and 2000,
respectively. Under an agreement with the OPUC, revenues from these sales are
treated as a reduction of gas costs.

          NW Natural has a PGA tariff in Oregon under which its net income from
Oregon operations is affected only within defined limits by changes in purchased
gas costs. 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 projections.
The remaining 67 percent of the higher or lower gas costs is recorded as
deferred debits or credits (regulatory assets or liabilities) for recovery from
or refund to customers in future rates. NW Natural deferred $2.3 million of
higher gas costs during the second quarter of 2001 and $6.2 million
year-to-date, and expects to recover these amounts from customers during the
next two years. The combined impact of NW Natural's higher gas costs and its
partially offsetting off-system gas sales under the PGA sharing mechanism during
the second quarter of 2001 was that the Company absorbed $0.7 million of its
higher gas costs, reducing earnings by about 2 cents a share.


                                       17



     Non-utility Operations
     ----------------------

          At June 30, 2001 and 2000, the Company had one active subsidiary,
Financial Corporation, a wholly-owned subsidiary. One discontinued segment,
Canor, a majority-owned subsidiary, was sold in January 2000 (see "Discontinued
Segment," below).

          Financial Corporation
          ---------------------

          Financial Corporation's operating results for the three months ended
June 30, 2001 were net income of $0.2 million, equivalent to 1 cent a share,
compared to a loss of $0.4 million, or 2 cents a share, for the second quarter
of 2000. Year-to-date, operating results were net income of $0.3 million,
compared to a loss of $0.2 million for the comparable period in 2000. Results
were weaker for the six months ended June 30, 2000 due to adjustments totaling
$0.6 million to Financial Corporation's deferred income tax accounts recorded in
the second quarter of 2000. Financial Corporation's net assets at June 30, 2001
were $7.6 million, compared to $7.0 million at June 30, 2000.

          Discontinued Segment
          --------------------

          During the first quarter of 2000, the Company sold its interest in
Canor at a gain of $2.5 million, equivalent to 10 cents a share (see Item 1,
Note 8., "Notes to Consolidated Financial Statements," above, and Part II, Item
7., "Results of Operations - Discontinued Segment," in the 2000 Form 10-K).

          Gas Storage Services
          --------------------

          The Company realized net income after-tax of $0.4 million, or 1 cent a
share, in the three months ended June 30, 2001 and $1.1 million, or 4 cents a
share, year-to-date, from gas storage services to customers using storage
capacity not required from time to time for utility services. Gas storage net
income for the three and six months ended June 30, 2000 was negligible.

     Operating Expenses
     ------------------

          Operations and Maintenance
          --------------------------

          Operations and maintenance expenses increased $2.4 million, or 13
percent, and $4.5 million, or 12 percent, in the three and six month periods
ended June 30, 2001, respectively, compared to the same periods in 2000. Key
factors that contributed to the increases in the current year periods were
higher employees' health and life insurance benefit costs, higher uncollectible
accounts expense, higher payroll costs due to wage and salary increases and
increases in weatherization program costs.

          Taxes Other than Income Taxes
          -----------------------------

          Taxes other than income taxes increased $1.6 million, or 11 percent,
in the first six months of 2001 compared to the first half of 2000. Franchise
tax expense increased $0.9 million due to higher utility operating revenues and
property taxes increased $0.4 million due to utility plant additions. Also,
regulatory fees and payroll tax expenses increased slightly.

          Depreciation, Depletion and Amortization
          ----------------------------------------

          The Company's depreciation, depletion and amortization expense
increased $1.2 million, or 5 percent, compared to the first six months of 2000.
The increase was primarily due to a 5 percent increase in utility plant in
service. Depreciation, depletion and amortization expense was approximately 2
percent of average plant and property for the six months ended June 30, 2001 and
2000.


                                       18



     Other Income (Expense)
     ----------------------

          The Company's other income (expense) decreased $1.4 million and $1.5
million in the three and six month periods ended June 30, 2001, respectively,
compared to the same periods in 2000. The decreases in both periods were
primarily due to lower interest income on deferred regulatory account balances,
miscellaneous non-operating income and investment income from Company-owned life
insurance policies, offset by higher net rental income. During the three months
ended June 30, 2001, an adjustment relating to the treatment of gas storage
inventory under NW Natural's PGA mechanism reduced interest income by $0.4
million (see "Cost of Gas," above).

     Interest Charges - net
     ----------------------

          The Company's net interest expense decreased by $0.3 million, or 2
percent, in the six months ended June 30, 2001 compared to the same period in
2000 due to lower average balances of short term debt and lower average interest
rates.

     Income Taxes
     ------------

          The effective corporate income tax rates from continuing operations
for the three months ended June 30, 2001 and 2000, were 32.9 percent and 24.4
percent, respectively. The difference in tax rates between the respective
quarters was primarily due to a reduction in income tax expense ($0.2 million)
at June 30, 2000 as a result of true-up adjustments to the 1999 federal and
state income tax returns. Year-to-date, the effective corporate income tax rates
from continuing operations was 36.4 percent, compared to 35.9 percent at June
30, 2000.

Financial Condition
- -------------------

     Capital Structure
     -----------------

          NW Natural's capital expenditures are primarily related to utility
construction resulting from customer growth and system improvements. NW Natural
finances these expenditures from cash provided by operations and from short-term
borrowings which are periodically refinanced through the sale of long-term debt
or equity securities. In addition to its capital expenditures, the
weather-sensitive nature of revenue derived from gas usage by NW Natural's
residential and commercial customers influences the Company's financing
requirements from one quarter to the next. Short-term liquidity is satisfied
primarily through the sale of commercial paper, which is supported by commercial
bank lines of credit (see Part II, Item 8., Note 6, "Notes to Consolidated
Financial Statements," in the 2000 Form 10-K).

          The Company's long-term goal is to maintain a capital structure
comprised of 45 to 50 percent common stock equity, 5 to 10 percent preferred and
preference stock and 45 to 50 percent short-term and long-term debt. When
additional capital is required, the Company issues debt or equity securities
depending upon both the target capital structure and market conditions. The
Company also uses these sources to meet long-term debt and preferred stock
redemption requirements (see Part II, Item 8., Notes 3 and 5, "Notes to
Consolidated Financial Statements," in the 2000 Form 10-K).


                                       19



     Cash Flows
     ----------

          Operating Activities
          --------------------

          Continuing operations provided net cash of $82.7 million in the six
months ended June 30, 2001, compared to $103.4 million in the first six months
of 2000. The 20 percent decrease was due to decreased cash from operations
before working capital changes ($6.2 million) and higher working capital
requirements ($14.5 million). The decrease in cash from continuing operations
before working capital changes was due to a larger increase in deferred income
taxes and investment tax credits in 2001 ($4.1 million), lower income from
continuing operations ($0.9 million) and smaller reductions in deferred gas cost
receivable ($1.7 million) and earnings of equity investments ($0.4 million) in
2001, partially offset by an increase in depreciation, depletion and
amortization in 2001 ($1.2 million). The increase in working capital
requirements was primarily due to a larger reduction in accounts payable ($46.6
million), partially offset by larger reductions in accounts receivable ($11.4
million), accrued unbilled revenues ($10.9 million) and inventories of gas,
materials and supplies ($9.8 million).

          The Company has lease and purchase commitments relating to its
operating activities which are financed with cash flows from operations (see
Part II, Item 8., Note 12, "Notes to Consolidated Financial Statements," in the
2000 Form 10-K).

          Investing Activities
          --------------------

          Cash requirements for utility construction in the first six months of
2001 totaled $35.8 million, down $2.2 million from the first six months of 2000.

          NW Natural's construction expenditures for 2001 were initially
estimated at $75 million. In April 2001, however, the Company accelerated plans
for an additional $10 million investment in storage facilities, increasing the
projected total construction budget for 2001 to $85 million. Over the five-year
period 2001 through 2005, these expenditures are estimated at between $450
million and $500 million. The level of capital expenditures over the next five
years reflects projected high customer growth plus a major system reinforcement
project and the development of additional underground gas storage facilities. An
estimated 60 percent of the required funds is expected to be internally
generated over the five-year period, with the remainder funded through a
combination of long-term debt and equity securities, with short-term debt
providing liquidity and bridge financing.

          Investments in non-utility property during the first six months of
2001 were negligible. The $0.6 million investment in non-utility property in the
first six months of 2000 consisted of final costs for the construction of the
new headquarters building for the Port of Portland (see Item 1, Note 7, "Notes
to Consolidated Financial Statements," above). The discontinued segment provided
net cash of $34.8 million in the first quarter of 2000 from sale of the
Company's interest in Canor.

          Financing Activities
          --------------------

          Cash used for financing activities in the first six months of 2001
totaled $41.2 million, a decrease of $58.7 million from the first six months of
2000. Proceeds from the sales of $18 million of Medium-Term Notes, Series B, in
June 2001, together with internally generated cash, were used to reduce
short-term debt ($38.3 million). Internally generated cash, including proceeds
from the sale of Canor ($34.8 million), was used to reduce short-term debt
($83.8 million) in the first six months of 2000.

          In May 2000, the Company commenced a program to repurchase up to 2
million shares, or up to $35 million in value, of NW Natural's common stock
through a repurchase program which has been extended through May 2002. The


                                       20



purchases are made in the open market or through privately negotiated
transactions. The Company used $5.8 million for the repurchase of 246,700 shares
under the program in the first six months of 2001. The Company has repurchased
355,400 shares of common stock at a total cost of $8.2 million from the
program's inception through June 30, 2001.

     Commercial Paper
     ----------------

          The Company's primary source of short-term funds is commercial paper.
Both NW Natural and Financial Corporation issue commercial paper under agency
agreements with a commercial bank. The commercial paper is supported by bank
lines of credit (see "Lines of Credit," below). Financial Corporation's
commercial paper is supported by the guaranty of NW Natural (see Part II, Item
8., Note 6, "Notes to Consolidated Financial Statements," in the 2000 Form
10-K). NW Natural had $18.0 million of commercial paper notes outstanding at
June 30, 2001, compared to $10.3 million and $56.3 million at June 30 and Dec.
31, 2000, respectively. Financial Corporation had no commercial paper notes
outstanding at Dec. 31, 2000, or June 30, 2001 or 2000.

     Lines of Credit
     ---------------

          NW Natural has available through Sept. 30, 2001 committed lines of
credit with four commercial banks totaling $120 million which are used as backup
lines for the commercial paper program. In addition, Financial Corporation has
available through Sept. 30, 2001 committed lines of credit with two commercial
banks totaling $20 million. Financial Corporation's lines are supported by the
guaranty of NW Natural.

          Under the terms of these lines of credit, NW Natural and Financial
Corporation pay commitment fees but are not required to maintain compensating
bank balances. The interest rates on borrowings are based on current market
rates as negotiated. There were no outstanding balances on either the NW Natural
or Financial Corporation lines of credit as of Dec. 31, 2000, or June 30, 2001
or 2000.

     Ratios of Earnings to Fixed Charges
     -----------------------------------

          For the 6 months and 12 months ended June 30, 2001, and the 12 months
ended Dec. 31, 2000, the Company's ratios of earnings to fixed charges, computed
using the Securities and Exchange Commission method, were 3.77, 3.05 and 3.14,
respectively. For this purpose, earnings consist of net income before 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.
