ITEM 1. BUSINESS

COMPANY OVERVIEW

Avista Corporation (Avista Corp., or the Company), formerly known as The
Washington Water Power Company, was incorporated in the State of Washington in
1889, and is a diversified energy services company. The name change to Avista
Corporation became effective on January 1, 1999. At December 31, 1998, the
Company's employees included 1,536 people in its utility operations and
approximately 2,153 people in its majority-owned non-regulated businesses
(energy and non-energy). The Company's corporate headquarters are in Spokane,
Washington (Spokane), which serves as the Inland Northwest's center for
manufacturing, transportation, health care, education, communication,
agricultural and service businesses.

Regulatory, economic and technological changes have brought about the
accelerating transformation of the electric utility industry from a vertically
integrated monopoly to separate market driven businesses. Changes underway in
the utility and energy industries are creating new opportunities to expand the
Company's businesses and serve new markets. In pursuing such opportunities, the
Company is shifting its strategic direction to growth in order to achieve its
goal of becoming a diversified North American energy company. The Company's
strategies are described below.

The Company seeks to strengthen its position of leadership in energy delivery
and generation as well as energy trading and marketing on a local, regional and
national basis. The Company will seek to increase its asset and customer base
through a focus on acquisitions and strategic alliances in all parts of its
business. The Company intends to focus on growing its core energy business by
seeking to acquire control of physical assets, specifically power generation
assets and electric and natural gas transmission and distribution assets. The
Company expects that initial growth will come at a local and regional level,
with national growth to follow. Key strengths of the Company today include its
position as one of the lowest cost producers of power in the nation, expertise
in hydroelectric and power system management, plus capabilities in trading and
wholesale and retail marketing of natural gas and electric energy.

Locally. The Company is a long-standing leader in the Northwest region of the
United States, providing some of the lowest cost energy to its customers. The
Company's strategy is to add selectively to its already strong foundation of
state-regulated utility assets to solidify its position as a leading supplier of
low-cost electric and natural gas energy services.

Regionally. The Company intends to add to its regulated and non-regulated assets
on a regional basis and participate in industry consolidation to further
optimize its assets and create greater economies of scale. In addition to energy
delivery and generation, the Company plans to concentrate on growing its energy
trading and marketing business. The strong growth in this business is expected
to be driven by the Company's significant base of knowledge and experience in
the operation of physical systems - for both natural gas and electric energy -
in the region, as well as its relationship-focused approach to the customer. The
Company will also focus on expanding its telecommunications business through its
newest subsidiary, Avista Communications. (See Non-Energy business for
additional information.)

Nationally. The Company's strong regional energy trading and marketing skills
serve as a platform for the Company's growing national presence. The Company
will seek to expand its customer base through Internet-based specialty billing
and information services and relationships with other energy providers outside
the Northwest, thereby leveraging its existing trading and marketing skills. On
February 1, 1999, Avista Energy, Inc., (Avista Energy) a national energy trading
and marketing subsidiary of Avista Corp. acquired Vitol Gas & Electric LLC, one
of the top 20 energy marketing companies in the United States. (See National
Energy Trading and Marketing for additional information.)

The Company conducts the majority of its Non-energy business through its wholly
owned subsidiary, Pentzer Corporation (Pentzer). Pentzer's business strategy is
to acquire controlling interests in a broad range of middle market companies,
facilitate improved productivity and growth, and ultimately sell such companies
to the public or a strategic buyer.

The Company's growth strategy will expose the Company to risks associated with
rapid expansion, challenges in recruiting and retaining qualified personnel,
risks associated with acquisitions, joint ventures and increasing competition.
In addition, growth in the energy and trading and marketing business will expose
the Company to increased financial and credit risks associated with commodity
trading activities. The Company believes however, that its extensive experience
in the electric and natural gas business, coupled with its strong management
team, will allow the Company to effectively manage its transition to a
diversified North American energy company.

In order to implement its growth strategies, the Company has reorganized its
operations into four lines of business - Energy Delivery, Generation and
Resources, National Energy Trading and Marketing and Non-energy. The regulated
utility

operations fall within Energy Delivery and Generation and Resources. The
Energy Delivery business includes retail electric and natural gas distribution
and transmission services. The Generation and Resources business includes
generation and production, resource optimization, electric and natural gas
commodity trading and wholesale marketing. Both the Energy Delivery and
Generation and Resources lines of business fall within Avista Utilities, an
operating division of Avista Corp. Avista Capital, which is a wholly-owned
subsidiary of Avista Corp., owns all of the companies engaged in the National
Energy Trading and Marketing and Non-energy lines of Business. The National
Energy Trading and Marketing line of business includes Avista Advantage, Inc.
(Avista Advantage), Avista Energy, Inc. (Avista Energy) and Avista Power, Inc.
(Avista Power). See Item 1. Business - National Energy Trading and Marketing and
Notes 1, 3 and 4 of Notes to Financial Statements for additional information. As
of December 31, 1998 the Company had common equity investments of $216.6 million
($493.4 million including convertible securities) and $271.8 million in Avista
Utilities and Avista Capital, respectively. The Non-energy line of business,
also owned by Avista Capital, includes Avista Fiber, Inc. (Avista Fiber), Avista
Development, Inc. (Avista Development), Avista Labs, Inc. (Avista Labs), Avista
Communications, Inc. (Avista Communications) and Pentzer Corporation, which is
the parent company to the majority of the Company's non-energy businesses. See
Item 1. Business - Non-energy Business and Notes 1 and 17 of Notes to Financial
Statements for additional information.

Below is the list of major companies owned by Avista Capital:

Avista Energy - An electricity and natural gas marketing and trading
company.

ENERGY DELIVERY

GENERAL

Energy Delivery provides electricity and natural gas distribution and
transmission services in a 26,000 square mile area in eastern Washington and
northern Idaho with a population of approximately 825,000. Energy Delivery also
provides natural gas service in a 4,000 square mile area in northeast and
southwest Oregon and in the South Lake Tahoe region of California, with the
population in these areas approximating 495,000.

At the end of 1998, retail electric service was supplied to approximately
305,000 customers in eastern Washington and northern Idaho; retail natural gas
service was supplied to approximately 262,000 customers in parts of Washington,
Idaho, Oregon and California.

The Company expects economic growth to continue in its eastern Washington and
northern Idaho service area. The Company, along with others in the service area,
is continuing its efforts to facilitate expansion of existing businesses and
attract new businesses to the Inland Northwest. Agriculture, mining and lumber
were the primary industries for many years, but health care, education,
electronic and other manufacturing, tourism and the service sectors have become
increasingly important industries that operate in the Company's service area.
The Company also anticipates moderate economic growth to continue in its Oregon
service area.

The Company anticipates residential and commercial electric load growth to
average approximately 2.3% annually for the next five years primarily due to
increases in both population and the number of businesses in its service
territory. The number of electric customers is expected to increase and the
average annual usage by residential customers is expected to remain steady on a
weather-adjusted basis.

The Company anticipates natural gas load growth, including transportation
volumes, in its Washington and Idaho service area to average approximately 2.7%
annually for the next five years. The Oregon and South Lake Tahoe, California
service areas are anticipated to realize 3.1% growth annually during that same
period. Refer to Item 7. Management's Discussion and Analysis of Financial
Condition and Results of Operations: Results of Operations: Future Outlook for
additional information.

ELECTRIC OPERATIONS

Energy Delivery currently receives all of its electric supply from Generation
and Resources. (See Generation and Resources - Electric Resources for additional
information.)

Challenges facing the retail electric business include cost management,
self-generation and fuel switching by commercial and industrial customers, the
costs of increasingly stringent environmental laws and the potential for
stranded or non-recoverable utility assets. In April 1996, the Federal Energy
Regulatory Commission (FERC) issued Orders No. 888 and No. 889 which require
electric utility companies to provide third-party access to their transmission
systems and to establish an Open Access Same-time Information System (OASIS) to
provide transmission customers with information about available transmission
capacity, prices and other information, by electronic means. In addition, state
legislatures in the Company's service territory are continuing to evaluate
restructuring the retail electric business to full competition. When electric
utility companies are required to provide retail wheeling service, which is the
transmission of electric power from another supplier to a customer located
within such utility's service area, the Company believes it will face minimal
risk for stranded generation, transmission or distribution assets due to its low
cost structure. However, the Company cannot predict the potential impact, if
any, of restructuring the electric utility industry on the Company's future
financial condition and results of operations. (See Industry Restructuring and
Note 1 of Notes to Financial Statements for additional information.)

NATURAL GAS OPERATIONS

Natural gas remains competitively priced compared to alternative fuel sources
for residential, commercial and industrial customers. Because of abundant
supplies and competitive markets, natural gas should sustain its market
advantage. The Company continues to advise electric customers as to the cost
advantages of converting space and water heating needs to natural gas.
Significant growth has occurred in the Company's natural gas business in recent
years due to increased demand for natural gas in new construction. The Company
also makes sales and provides transportation service directly to large natural
gas customers and makes non-retail sales to marketers and producers where points
of delivery are outside the Company's retail distribution area.

AVISTA CORPORATION
- --------------------------------------------------------------------------------

Most of the Company's large industrial customers purchase their own natural gas
requirements through gas marketers. For these customers, the Company provides
transportation from the Company's pipeline interconnection to the customer's
plant. The Company has numerous special contracts for natural gas transportation
service, most of which contain negotiated rates for Company distribution service
based on the customer's competitive alternatives. Seven of the Company's largest
natural gas customers are provided natural gas transportation service by the
Company under special contracts. These negotiated contracts were entered into to
retain these customers who can either by-pass the Company's distribution system
or have competitive alternative fuel capability. All special contracts are
subject to regulatory review and approval. The competitive nature of the spot
natural gas market results in savings in the cost of purchased natural gas,
which encourages large customers with fuel-switching capabilities to continue to
utilize natural gas for their energy needs. The total volume transported on
behalf of transportation customers for 1998, 1997 and 1996 was approximately
226.1, 245.1 and 237.9 million therms, which represented approximately 39%, 43%
and 40% of the Company's total system deliveries. In addition, the Company sells
firm transportation to third parties when it is not needed to serve the
Company's customers.

NATURAL GAS RESOURCES

Natural Gas Supply A diverse portfolio of resources allows the Company to
capture market opportunities that benefit the Company's natural gas customers.
Natural gas supplies are available from both domestic and Canadian sources
through both long- and short-term, or spot market, purchases. The Company holds
capacity on six pipelines and owns natural gas storage facilities which allow
the Company to optimize its available resources.

Firm natural gas supplies are purchased by the Company through negotiated
agreements having terms ranging between one month and seven years. During 1998,
approximately one-third of the Company's purchases were in the short-term
market, with contracts on a month-to-month basis. Approximately 14% of the
natural gas supply was obtained from domestic sources, with the remaining 86%
from Canadian sources. Nearly all natural gas purchased from Canadian sources is
contracted in U.S. dollar denominations, limiting any foreign currency exchange
exposure. The Company does not consider Canadian natural gas supplies to be at
greater risk of non-delivery than U.S. supplies.

The Company holds capacity on six natural gas pipelines, Northwest Pipeline
Company (NWP), Pacific Gas Transmission (PGT), Paiute Pipeline (Paiute),
Tuscarora Gas Transmission Company (Tuscarora), NOVA Pipeline, Ltd. (NOVA) and
Alberta Natural Gas Co. Ltd. (ANG), which provide the Company access to both
domestic and Canadian natural gas supplies. In 1998, the Company obtained gas
from over 25 different suppliers.

The Company contracts with NWP for three types of firm service (transportation,
liquefied natural gas storage and underground storage), with Paiute for firm
transportation and liquefied natural gas storage and with PGT, Tuscarora, NOVA
and ANG for firm transportation only.

Jackson Prairie Natural Gas Storage Project (Storage Project) The Company owns a
one-third interest in the Storage Project, which is an underground natural gas
storage field located near Chehalis, Washington. The role of the Storage Project
in providing flexible natural gas supplies is increasingly important to the
Company's natural gas operations. It enables the Company to place natural gas
into storage when prices are low or to meet minimum natural gas purchasing
requirements, as well as to withdraw natural gas from storage when spot prices
are high or as needed to meet high demand periods. The Company is in the process
of increasing the capacity at the Storage Project. The increased capacity will
be optimized by Avista Energy for the next 10 years, and in return, Avista
Energy will be responsible for the capital costs related to the project
expansion. The Company has contracted to release some of its Storage Project
capacity to two other utilities until 2000 and 2001, with a provision under one
of the releases to partially recall the released capacity if the Company
determines additional natural gas is required for its own system supply.

ENERGY DELIVERY REGULATORY ISSUES

The Company, as a regulated public utility, is currently subject to regulation
by state utility commissions with respect to prices, accounting, the issuance of
securities and other matters. The retail electric operations are subject to the
jurisdiction of the Washington Utilities and Transportation Commission (WUTC),
the Idaho Public Utilities Commission (IPUC) and the Montana Public Service
Commission (MPSC). The retail natural gas operations are subject to the
jurisdiction of the WUTC, the IPUC, the Oregon Public Utility Commission (OPUC)
and the California Public Utilities Commission (CPUC). The Company is also
subject to the jurisdiction of the FERC for its (wholesale) natural gas rates
charged for the release of capacity from the Jackson Prairie Storage Project.

In each regulatory jurisdiction, the price the Company may charge for retail
electric and natural gas services (other than specially negotiated retail rates
for industrial or large commercial customers, which are subject to regulatory
review and approval) is currently determined on a "cost of service" basis and is
designed to provide, after recovery of allowable





5
10
AVISTA CORPORATION
- --------------------------------------------------------------------------------

operating expenses, an opportunity to earn a reasonable return on "rate base."
"Rate base" is generally determined by reference to the original cost (net of
accumulated depreciation) of utility plant in service, subject to various
adjustments for deferred taxes and other items (see Note 1 of Notes to Financial
Statements for additional information about regulation, depreciation and
deferred taxes). Over time, rate base is increased by additions to utility plant
in service and reduced by depreciation of utility plant. As the energy business
is restructured, traditional "cost of service" ratemaking may evolve into some
other form of ratemaking. Rates for transmission services are based on the "cost
of service" principles and are set forth in tariffs on file with the FERC. (See
Industry Restructuring for additional information.)

General Rate Cases The Company's last general electric rate cases were effective
in March 1987 for the State of Washington and September 1986 for the State of
Idaho; both allowed a return on equity of 12.90%.

On December 18, 1998, the Company filed for a general electric rate increase of
$14,223,000 or 11.56% with the IPUC. The Company is requesting a return on
equity of 12.00%. An order is expected in the latter part of 1999. The Company
anticipates filing for a retail increase in the State of Washington later in
1999.

On June 27, 1997, the Company filed a general natural gas rate increase of $7.87
million with the WUTC. A settlement agreement resulted in a $5 million, or 7.5%,
increase effective January 1, 1998. Included in the settlement agreement was a
stated return on equity of 10.75%. However, the agreements reached in the
settlement do not set a precedent for future rate filings. The Company's last
general natural gas rate cases involving litigated cost of capital resulted in
allowed return on equity of 12.90% for the State of Washington, effective August
1990 and 12.75% for the State of Idaho, effective October 1989.

Power Cost Adjustment (PCA) The Company has a PCA in Idaho which tracks changes
in hydroelectric generation, surplus energy prices, related changes in thermal
generation and the Public Utility Regulatory Policies Act of 1978 (PURPA)
contracts, but not changes in revenues or costs associated with other wheeling
or power contracts. Rate changes are triggered when the deferred balance reaches
$2.2 million, provided no more than two surcharges or rebates are in effect at
the same time. See Note 1 of Notes to Financial Statements for additional
information.

Service Territory Agreement In August 1998, the Company executed a new electric
service territory agreement with Inland Power and Light Company. Inland Power
and Light is an electric cooperative serving approximately 30,000 customers in
various suburban and rural areas of Eastern Washington, including areas around
Spokane. The Company had an existing service territory agreement with Inland
Power and Light that was due to expire in December 1998. The Company entered
into the new agreement in order to protect service provided to existing
customers and to establish rules for service to new customers. Under the
agreement, generally, the utility with the closest electric facilities will
serve a new customer. However, new customers with loads larger than 3 megawatts
can choose their service provider. The agreement is for a fifteen year term and
was approved by the WUTC on October 9, 1998.

Purchased Gas Adjustment (PGA or Natural Gas Trackers) Natural gas trackers are
supplemental tariffs filed with state regulatory commissions which are designed
to pass through changes in purchased natural gas costs and therefore, do not
normally result in any changes in net income to the Company. On September 30,
1998, the Company filed a PGA with the WUTC. This filing requested a net revenue
reduction of $42,000 or .06%. On December 1, 1998, a modified version of the
original filing became effective with rates subject to change based on the
WUTC's continuing audit. In January 1999, the audit was concluded with no
adjustment to rates, and in February 1999, the Commission closed the
investigation. In November 1998, the OPUC approved a $1.1 million, or 2.25%
decrease effective December 1, 1998. In October 1998, the Company filed a
natural gas tracker with the IPUC requesting a $1.1 million, or 4.0%, increase
which was approved, effective December 7, 1998.

Natural Gas Benchmark Mechanism
On December 1, 1998, the Company filed a proposal with the WUTC and IPUC to
eliminate gas procurement operations within Avista Utilities and consolidate gas
procurement operations under Avista Energy. A smaller natural gas staff would
remain in Avista Utilities to prepare load forecasts and support regulatory
activities. The ownership of the natural gas assets would remain with Avista
Utilities, but would be managed by Avista Energy through an agency agreement.

Consolidation of natural gas procurement operations under Avista Energy would
allow the Company to gain synergies and better manage its risk by combining and
operating the two portfolios as one portfolio and to gain efficiencies by
eliminating duplicate functions. The proposal to state regulators includes a Gas
Benchmark mechanism that is designed to provide certain guaranteed benefits to
retail customers as well as provide Avista Corp. the opportunity to improve
earnings, i.e., a performanced-based mechanism.

The Idaho Gas Benchmark mechanism sets three separate benchmarks or targets:
commodity, pipeline capacity and Jackson Prairie storage. To the extent that
Avista Energy optimizes these three components of gas costs, Avista Energy will
retain the benefits. Likewise, if Avista Energy incurs costs in excess of the
targets, it will absorb the loss.

The Gas Benchmark Mechanism was approved by the IPUC on February 1, 1999. The
proposal is currently pending before the WUTC and the Company is currently
working with WUTC staff to resolve issues in the proceeding. The Company is
preparing a similar proposal for its Oregon natural gas procurement operations.
The Company plans to file with the OPUC in March 1999.

GENERATION AND RESOURCES

GENERAL

The Generation and Resources line of business manages the Company's natural gas
and electric energy resource portfolio, which is used to serve Energy Delivery's
retail customers and Generation and Resources' wholesale customers. The primary
business focus of Generation and Resources is to optimize the availability and
operation of generation resources. The Company owns and operates eight
hydroelectric projects, a wood-waste fueled generating station and two natural
gas combustion turbine (CT) peaking units. See Item 2. Properties Generation and
Resources for additional information. The Company also owns a 15% share in two
coal-fired generating facilities and leases two additional gas CT peaking units.
With this diverse energy resource portfolio, the Company remains one of the
nation's lowest-cost producers and sellers of electric energy services.

The Company's wholesale marketing and trading business units within the
Generation and Resources line of business are a secondary, but very important
part of the Company's overall business strategy. Since 1987, the Company has
entered into a number of long-term power sales contracts that have increased its
wholesale electric revenues, and the Company is continuing to actively pursue
electric wholesale marketing and energy trading business opportunities. Energy
trading includes short-term sales and purchases such as next hour, next day and
monthly blocks of energy. Wholesale marketing includes sales and purchases under
long-term contracts with one-year and longer terms. Wholesale sales are affected
by weather and streamflow conditions and may eventually be affected by the
restructuring of the electric utility industry. (See Industry Restructuring for
additional information.)

Generation and Resources competes in the wholesale electric market with other
western utilities, federal marketing agencies and power marketers. The Company's
participation in the wholesale electric market allows the Company to maintain
presence in and knowledge of the market, resulting in maximum optimization of
the Company's resources. The wholesale electric market has changed significantly
over the last few years with respect to market participants, level of activity,
variability of prices, and per-unit margins. These changes have contributed to
the increased liquidity of the market, which in turn has increased transactional
volumes in the market. It is expected that competition in the wholesale power
market will remain vigorous.

Challenges facing Generation and Resources include evolving technologies, which
provide alternate energy supplies and deregulation of the retail electric
market. The Company believes it faces minimal risk for stranded generation
assets resulting from deregulation due to its low cost generation portfolio.
However, in a deregulated environment, evolving technologies which provide
alternate energy supplies could affect the market price of power, and certain
generating assets could have operating costs above the adjusted market price.
The Company continues to assess the costs and operation of its generation
portfolio in order to optimize the resources of the Company.

ELECTRIC REQUIREMENTS

The Company's 1998 annual peak requirements, including long-term and short-term
contractual obligations, were 4,765 MW. This peak occurred on December 21, 1998,
at which time the maximum capacity available from the Company's generating
facilities, including long-term and short-term purchases, was 4,991 MW. The
electric requirements include both Energy Delivery's electric needs and
Generation and Resources' wholesale short-term and long-term commitments, which
limits the amount of excess capacity available to support Generation and
Resources energy trading business.

ELECTRIC RESOURCES

The Company's diverse resource mix of hydroelectric projects, thermal generating
facilities and power purchases and exchanges, combined with strategic access to
regional electric transmission systems, enables the Company to remain one of the
nation's lowest-cost producers and sellers of electric energy services. At
December 31, 1998, the Company's total owned resources available were 58%
hydroelectric and 42% thermal. See Generation and Resources Operating Statistics
on page 13 for the Company's energy resource statistics.

Hydroelectric Resources Hydroelectric generation is the Company's lowest cost
source of electricity and the availability of hydroelectric generation has a
significant effect on the Company's total energy costs. Under average operating
conditions, the Company meets about one-third of its total energy requirements
(both retail and long-term wholesale), with its own hydroelectric generation and
long-term hydroelectric contracts. The streamflows to Company-owned
hydroelectric projects were 94%, 172% and 145% of normal in 1998, 1997 and 1996,
respectively. Total hydroelectric resources provide 524 aMW annually.

Thermal Resources The Company has a 15% interest in each of two twin-unit
coal-fired facilities - the Centralia Power Plant in western Washington and
Units 3 and 4 of the Colstrip Generating Project in southeastern Montana. In
addition, the Company owns a wood-waste-fired facility known as the Kettle Falls
Generating Station in northeastern Washington and two natural gas-fired CTs,
located in Spokane, used for peaking needs. The Company also operates and leases
two natural gas-fired CTs in northern Idaho, used for peaking needs. Total
thermal resources provide 339 aMW annually.



10
15
AVISTA CORPORATION
- --------------------------------------------------------------------------------

Centralia, which is operated by PacifiCorp, is supplied with coal under both a
fuel supply agreement in effect through December 2020 and various spot market
purchases. In 1998, 1997 and 1996, Centralia provided approximately 37%, 38% and
46%, respectively, of the Company's thermal generation. (See Environmental
Issues for additional information.)

Colstrip is supplied with fuel under coal supply and transportation agreements
in effect through December 2019 from adjacent coal reserves. The Montana Power
Company is the operator of Colstrip. In 1998, 1997 and 1996, Colstrip provided
approximately 46%, 47% and 34% of the Company's thermal generation,
respectively.

Kettle Falls' primary fuel is wood-waste generated as a by-product from forest
industry operations within one hundred miles of the plant. Natural gas may be
used as an alternate fuel. A combination of long-term contracts plus spot
purchases provides the Company the flexibility to meet expected future fuel
requirements for the plant. In 1998, 1997 and 1996, Kettle Falls provided
approximately 9%, 11% and 10% of the Company's thermal generation, respectively.

The four CTs are natural gas-fired units, primarily used for peaking needs. Two
CTs have access to domestic and Canadian natural gas supplied through PGT. In
1998, 1997 and 1996, these four units provided approximately 8%, 4% and 10%,
respectively, of the Company's thermal generation. Thermal generation from CTs
during 1997 was lower than other years primarily due to the cost of natural gas
as compared to alternative energy supplies.

Purchases, Exchanges and Sales In 1998, the Company had various long-term
purchase contracts with non-coincidental peak (peak that does not occur during
the same hour) equating to 457 MW, with an average remaining life of 5.3 years.
Additionally, long-term hydro purchase contracts of 197 MW peak were available
with an average remaining contract life of 12.8 years. The Company also enters
into a significant number of short-term sales and purchases with durations of up
to one year. Energy purchases and exchanges for the years 1998, 1997 and 1996
provided approximately 70%, 65% and 54%, respectively, of the Company's total
electric energy requirements, which reflects increased wholesale trading and
resource optimization activity.

Under PURPA, the Company is required to purchase generation from qualifying
facilities, including small hydroelectric and cogeneration projects, at avoided
cost rates adopted by the WUTC and the IPUC. The Company purchased approximately
563,000 MWH, or about 2% of the Company's total energy requirements, from these
sources at a cost of approximately $27 million in 1998. These contracts expire
in 1999-2022.

HYDROELECTRIC RELICENSING

The Company is a licensee under the Federal Power Act, which regulates certain
of the Company's generation resources and is administered by the FERC, and its
licensed projects are subject to the provisions of Part I of that Act. These
provisions include payment for headwater benefits, condemnation of licensed
projects upon payment of just compensation and take-over of such projects after
the expiration of the license upon payment of the lesser of "net investment" or
"fair value" of the project, in either case plus severance damages. All but one
of the Company's hydroelectric plants are regulated by the FERC through project
licenses issued for 30-50 year periods. See Item 2. Properties - Generation and
Resources for additional information.

The Cabinet Gorge and Noxon Rapids plants are currently in the process of
relicensing with licenses expiring February 2001. The Company filed a Notice of
Intent to relicense in 1996 and has since consulted with resource agencies,
Native American tribes, special interest groups and the general public regarding
its relicensing.

The Company's approach to relicensing departed significantly from the
conventional FERC process. Early FERC involvement and Environmental Impact
Statement scoping occurred prior to the application and the consultation process
was expanded to a comprehensive collaborative process including all
stakeholders. The collaborative process used by the Company is nationally
recognized as the model for FERC's alternative approach to relicensing.

The Company reached a settlement agreement with all parties on January 28, 1999
that resolved all environmental, tribal, and operational issues regarding
relicensing of Cabinet Gorge and Noxon Rapids. As part of the agreement, Avista
Corp. committed to early implementation of protection, mitigation, and
enhancement measures beginning in March 1999. Measures in the agreement which
will cost approximately $4.7 million annually, address fisheries, water quality,
wildlife, recreation, land use, cultural resources and erosion, and represents
the results of studies and interests of over 40 organizations and 100
individuals. See Item 2. Properties - Generation and Resources and Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations: Future Outlook for additional information.

The license application for Cabinet Gorge and Noxon Rapids was filed with FERC
on February 18, 1999 and included the settlement agreement signed by 27 parties
and a collaboratively written environmental assessment report. For hydroelectric
projects of this size, it is unprecedented to have reached settlement two years
before the license expires, while preserving the projects economic peaking and
load following operations.

GENERATION AND RESOURCES REGULATORY ISSUES

The Company, with respect to Generation and Resources, is subject to the
jurisdiction of the FERC for its accounting procedures and its wholesale
electric rates. Some wholesale electric rates are determined on a
"cost-of-service" basis in a




11
16
AVISTA CORPORATION
- --------------------------------------------------------------------------------

manner similar to retail rates. See Energy Delivery - Regulatory Issues for
additional information. Generally, rates for wholesale electric sales by the
Company for terms up to five years are based on market prices.

NATIONAL ENERGY TRADING AND MARKETING

The companies within the National Energy Trading and Marketing line of business
are Avista Energy, Avista Advantage and Avista Power, each of which is a
wholly-owned subsidiary of Avista Capital. Avista Capital's total equity
investment in this line of business was approximately $104.6 million on December
31, 1998.

Avista Energy

Avista Energy is one of the nation's fastest growing electricity and natural gas
marketing and trading companies. Avista Energy's headquarters are in Spokane,
Washington with offices in Houston, Texas; Boston, Massachusetts; Vancouver,
British Columbia, Canada; and Portland, Oregon. Avista Energy is in the business
of buying and selling natural gas and electricity. Avista Energy purchases
natural gas and electricity directly from producers and other trading companies,
and Avista Energy's customers include commercial and industrial end-users,
electric utilities, natural gas distribution companies and other trading
companies. Avista Energy also trades natural gas and electricity derivative
financial instruments, including futures, options, swaps and other contractual
arrangements on national exchanges and through other unregulated exchanges and
brokers from whom these commodity derivatives are available. In 1998, Avista
Energy sold approximately 54.4 million MWh of electric energy and 424.2 million
dekatherms of natural gas. This compares with approximately 4.5 million MWh of
electric energy and 67.3 million dekatherms of natural gas during five months of
operations in 1997.

Avista Energy's business is affected by several factors, including:

o the demand for and availability of energy throughout the United States,

o lower unit margins on new sales contracts,

o fewer long-term power contracts being entered into, resulting in a
heavier reliance on short-term power contracts which have lower margins
than long-term contracts,

o marginal fuel prices, and

o deregulation of the electric utility industry

Avista Energy operates in North America, principally within the West and
Mid-West United States and Western Canada. Avista Energy seeks to strengthen its
position of leadership in energy trading and marketing on a regional and
national basis through a focus on acquisitions and strategic alliances. Avista
Energy has entered new markets throughout North America, and will continue to
strategically acquire additional assets and customers.

Effective February 1, 1999, Avista Energy purchased Vitol Gas & Electric, LLC,
one of the top 20 energy marketing companies in the United States. With this
acquisition, Avista Energy now has an additional platform from which it can
further grow its national presence. The combined operation expands Avista
Energy's successful coast-to-coast commercial energy platform to the eastern
seaboard.

On December 16, 1998, Avista Energy Canada, Ltd., a wholly-owned subsidiary of
Avista Energy, acquired Coast Pacific Management, Inc. (Coast Pacific), a
natural gas marketing company based in Vancouver, British Columbia, Canada.
Coast Pacific manages and transports approximately 70,000 MMBtu of natural gas
per day to some 70 large and medium size industrial customers throughout British
Columbia. Coast Pacific acts as gas manager for more than 40 percent of the
large industrial market in the interior of British Columbia. The Coast Pacific
acquisition strengthened Avista Energy's Canadian operations with more access to
end-use customers, ties with British Columbia natural gas producers and expanded
Avista Energy's presence in Pacific Northwest natural gas markets.

In April 1997, Avista Energy contracted with Chelan County Public Utility
District (Chelan PUD), located in Washington State. The terms of the alliance
made this announcement the first of its kind in the Northwest. The agreement
allows the Company to market, on a "real-time" basis, a portion of the
significant output from Chelan PUD's hydroelectric resources and to jointly
market energy products and services to other utilities in the region.
Twenty-eight percent or 557 megawatts of total generated capacity of the dams
are available for real-time scheduling and resource optimization. The two
entities offer a variety of products, all designed to help smaller utilities
adjust to the emerging energy market. On October 20, 1997, a complaint for
declaratory and injunctive relief was filed in Chelan County Superior Court by
James A. Brown, a taxpayer and ratepayer of the District, in order to determine
whether the joint marketing and real-time scheduling efforts of Chelan PUD and
Avista Energy are within Chelan PUD's lawful authority to undertake. Avista
Energy and Chelan PUD continue to operate under the contractual alliance. The
outcome of this litigation is still pending and Avista Energy is unable to
assess the likelihood of an adverse outcome or estimate an amount or range of
potential loss in the event of an adverse outcome.

In June 1997, Avista Energy formed an alliance with Energy West Incorporated, a
diversified energy and retail propane company in Montana, to develop and
implement a direct access, retail power marketing business in Montana. The
alliance has not been active since its formation and both companies have agreed
to discontinue the alliance in 1999.

Effective November 30, 1998, Avista Energy sold its 50% ownership interest in
Howard/Avista Energy, LLC to H&H Star Energy, Inc. The sales price, which
represented Avista Energy's equity investment, was $25 million in the form of a
short term unsecured note receivable from H&H Star Energy, Inc. The Note is
guaranteed by H&H Star Energy, Inc.'s parent

- --------------------------------------------------------------------------------

company, Howard Publications, Inc and is due April 30, 1999.

In 1997, Avista Energy entered into a contract with Mock Energy Services to form
Avista/Mock Energy, LLC to provide integrated energy services to customers
throughout the state of California. Avista Energy agreed to the dissolution of
Avista/Mock Energy, LLC and affairs were wound up November 30, 1998. Avista/Mock
Energy, LLC conducted no business. All related costs of this investment were
recognized in 1998.

The participants in the emerging wholesale energy market are public utility
companies and, increasingly, power marketers which may or may not be affiliated
with public utility companies or other entities. The participants in this market
trade not only electricity and natural gas as commodities but also derivative
commodity instruments such as futures, forwards, swaps, options and other
instruments. This market is largely unregulated and most transactions are
conducted on an "over-the-counter" basis, there being no central clearing
mechanism (except in the case of specific instruments traded on the commodity
exchanges). Power marketers, whether or not affiliated with other entities,
generally do not own production facilities and are not subject to net capital or
other requirements of any regulatory agency.

Avista Energy is subject to the various risks inherent in commodity trading
including, particularly, market risk and credit risk.

Avista Capital provides guarantees for Avista Energy's line of credit agreement,
and in the course of business may provide guarantees to other parties with whom
Avista Energy may be doing business.

energy trading business, the Company's and Avista Energy's risk management
policies and procedures, accounting practices and positions held at December 31,
1998.

Avista Power

Avista Power was created in December 1998 to develop and own generation assets,
primarily in support of Avista Energy's commodity trading activities. Avista
Power and Cogentrix Energy, Inc. have entered into an agreement to jointly build
and/or buy interests in natural gas-fired electric generation plants in the
Pacific Northwest states of Washington, Oregon and Idaho. The first project
under the new agreement is an approximately 270 megawatt facility to be located
in Rathdrum, Idaho. The total cost of the project is estimated at $150 million;
Avista Power's share of the costs is approximately $75 million.

NON-ENERGY BUSINESS

Pentzer, which is a wholly-owned subsidiary of Avista Capital, is the dominant
company in the Non-energy line of business. At December 31, 1998, Avista
Capital's total equity investment in this line of business was approximately
$167.2 million, of which $140.1 million related to Pentzer.

Pentzer

Pentzer is the parent company for a majority of Avista Corp.'s non-utility
subsidiaries. Pentzer's portfolio of investments includes companies involved in
consumer product promotion, store fixtures, specialty tool manufacturing, metal
fabrication, financial services and electronic technology.

Pentzer's current investment profile focuses on manufacturers and distributors
of industrial and consumer products as well as service businesses. The Company
seeks businesses with above average records of earnings growth in industries
that are not cyclical or dependent upon high levels of research and development.
Emphasis is placed on leading companies with strong market franchises, dominant
or proprietary product lines or other significant competitive advantages.
Pentzer is particularly interested in companies serving niche markets. Total
equity investment in any one company is generally limited to $15 million, and
control of the acquired company's board of directors is generally required.

Pentzer's business strategy is to acquire controlling interest in a broad range
of middle-market companies, to help these companies grow through internal
development and strategic acquisitions, and to sell the portfolio investments
either to the public or to strategic buyers when it becomes most advantageous in
meeting Pentzer's return on invested capital objectives. Pentzer's goal is to
produce financial returns for the Company's shareholders that, over the
long-term, should be higher than that of the utility operations. From time to
time, a significant portion of Pentzer's earnings contributions may be the
result of transactional gains. Transactional gains arise from a one-time event
or a specific transaction, such as the sale of an investment or individual
company from Pentzer's portfolio of investments. Non-transactional earnings
arise out of the ongoing operations of the individual portfolio companies.
Accordingly, although the income stream is expected to be positive, it is not
predictable from year to year and may be uneven.

Other Non-Energy Companies

Other non-energy subsidiaries under Avista Capital include Avista Development,
Avista Labs, Avista Communications and Avista Fiber. Avista Development manages
and markets the corporation's community investments, including real-estate and
other assets. Avista Labs develops fuel cells and multiple fuel processing
approaches using propane, methane and methanol as base fuels to integrate into
its fuel cell subsystem. In September 1998, Avista Labs was awarded a $2.0
million technology development grant from the Department of Commerce's National
Institute of Standards and Technology Advanced Technology Program to fund
continuing research in alternate power solutions. Avista Communications, formed
in January 1999, is the newest of the non-energy subsidiaries. It will provide
local high-speed telecommunications services to under-served Northwest
communities. Avista Communications is a sister company to Avista Fiber, which
focuses on building high-speed local dark fiber networks in Northwest
communities.

INDUSTRY RESTRUCTURING

FEDERAL LEVEL

Industry restructuring to remove certain barriers to competition in the electric
utility industry was initially promoted by federal legislation. The Energy
Policy Act of 1992 (Energy Act) confers expanded authority upon the FERC to
issue orders requiring electric utilities to transmit power and energy to or for
wholesale purchasers and sellers, and to require electric utilities to enlarge
or construct additional transmission capacity for the purpose of providing these
services.

The FERC issued its final rule in Order No. 888 in April 1996. That order
requires public utilities operating under the Federal Power Act to provide
access to their transmission systems to third parties pursuant to the terms and
conditions of the FERC's pro-forma open access transmission tariff. Utilities
were required to file an open access tariff, allowing only limited variations to
the pro-forma tariff to reflect regional operating practices. Utilities were
also required to take transmission service under this same tariff. The Company
filed its open access tariff with the FERC in July 1996 and subsequently began
providing transmission service under the tariff. The FERC issued its initial
order accepting the non-rate terms and conditions of the Company's tariff in
November 1996.

In the FERC's Order No. 889, the companion rule to Order No. 888, the FERC
required public utilities to establish a system, OASIS, to provide transmission
customers with information about available transmission capacity, prices and
other information, by electronic means. This enables customers to obtain
transmission service in a non-discriminatory fashion. The final rule requires
each public utility subject to the rule to functionally separate its
transmission and wholesale power merchant functions, and prescribed standards of
conduct under which it assures that the utility's wholesale power merchant
function and competitors obtain information about its transmission system in the
same manner. The Company filed its "Procedures for Implementing Standards of
Conduct under FERC Order No. 889" with the FERC in December 1996 and adopted
these Procedures effective January 3, 1997. FERC Orders No. 888 and No. 889 have
not had a significant material effect on the operating results of the Company.

The Company and various Northwest utilities began investigating the feasibility
of transferring certain operational responsibilities associated with a regional
transmission grid to an independent grid operator. In November 1997, the Company
withdrew from the effort to establish an independent grid operator in the
Northwest because the costs were greater than the perceived benefits. The
Company is exploring other regional transmission alternatives intended to help
facilitate a competitive electric power market, including the development of an
independent grid scheduling entity which might provide quantifiable efficiencies
in administering access to the Northwest transmission system in a
non-discriminatory fashion.

The North American Electric Reliability Council and the WSCC have undertaken
initiatives to establish a series of security coordinators to oversee the
reliable operation of the regional transmission system. Accordingly, the
Company, in cooperation with other utilities in the Pacific Northwest, has
established the Pacific Northwest Security Coordinator (PNSC) which will oversee
daily and short-term operations of the northwest sub-regional transmission grid,
and have limited authority to direct certain actions of control area operators
in the case of a pending transmission system emergency. The Company executed its
service agreement with the PNSC in September 1998. The PNSC is currently
operating in a limited fashion and is expected to be fully operational by May
1999.

STATE LEVEL

Further competition may be introduced by state action. Competition for retail
customers is not generally allowed in the Company's service territory. While the
Energy Act precludes the FERC from mandating retail wheeling, state regulators
and legislators could open service territories to full competition at the retail
level. Legislative action at the state level would be required for full retail
wheeling to occur in Washington and Idaho.

During 1997, the Idaho Legislature enacted legislation requiring the IPUC to
compile utilities' costs separately by generation, transmission and
distribution. Early in 1998, the IPUC opened individual cases for each of the
investor owned utilities and pursued audits of their cost of service studies,
including results of operations, methodology, and allocations. In August 1998,
the Commission ordered the cases closed, concluding that these studies met the
legislative requirement and that further examination of unbundled costs would be
more appropriate in general rate proceedings.

Two restructuring "study bills" were adopted in the 1998 Washington Legislative
session covering examination of cost unbundling, development and disclosure of
consumer protection policies, and studies of deregulation and system
reliability. The first study bill, known as "ESSHB2831", was implemented by the
WUTC as a collaborative effort, including stakeholders, to examine unbundling
and related issues. Unbundling would require utilities to compile costs
separately by generation, transmission and distribution. In September 1998,
unbundled cost filings were submitted by Washington's investor-owned utilities
and by various public utilities that met certain size or customer density
parameters. The WUTC staff and the State Auditor jointly reviewed the studies
and prepared a report presenting the results of the individual utilities'
studies. The report was prepared in a format intended to allow the legislature
to analyze the potential impacts of restructuring and deregulation. The WUTC
staff summary report did not include recommendations for restructuring, it
merely presented pros and cons of restructuring on an issue by issue basis. From
this, the legislature will determine whether or not to pursue changes in the
laws governing the industry.




18
23
AVISTA CORPORATION
- --------------------------------------------------------------------------------

The second study bill "ESSB 6560" called for the examination of potential
quality of service, public purposes (e.g. conservation) and reliability issues
resulting from electric restructuring. The WUTC and the Washington Department of
Community, Trade and Economic Development launched the study, which was intended
to assist in the determination of appropriate reliability measures and the
feasibility of statewide compliance standards. Direct recommendations to the
legislature for implementation were not included, rather the focus was on a
"macro" analysis of the utilities' existing operations and theoretical impacts
on customer service quality and system reliability (generation, transmission,
and distribution) under various restructuring scenarios.

In 1998, the WUTC closed its Electric Industry Restructuring Inquiry initiated
in December 1995. The WUTC issued eight guiding principles including, a
directive that future WUTC regulatory oversight will balance such issues as
reliability, pricing responsive to customers needs and selected public policy
concerns.

The Company has developed a model offering broader customer choice to small
customers. The Portfolio Access Model (PA Model) was developed as a transition
to full direct access. Under the PA Model, large-use customers would receive
direct access; small-use customers would be provided a menu of services priced
at market rates such as monthly and annual pricing, as well as optional "green
rates" for renewable power. The PA Model has served as a regional proposal under
discussion by legislative committees and work groups in Washington, Idaho and
Oregon. More Options for Power Services II (MOPS II) is the Company's PA Model
regulatory pilot. (See Experimental Programs below for additional information.)

On December 31, 1997, the Company filed an application for exemption from the
California Public Utilities Commission's Affiliate Transaction Rules. These
rules require that a utility's energy marketing affiliates follow detailed
operating and reporting protocols as well as full separation from the regulated
entity for any business activity in California. On January 20, 1999, the CPUC
granted the Company a full exemption to these rules, providing that the Company
complies with its voluntary agreement that none of its affiliates will
participate in its South Lake Tahoe service territory. The Company will also
provide periodic reports from an independent auditor verifying that its
affiliates have not participated within this service territory.

EXPERIMENTAL PROGRAMS

To assess impacts of competition and customer choice, the Company implemented
the following experimental programs: Direct Access and Delivery Service Tariff
(DADS), More Options for Power Services (MOPS) tariff and More Options for Power
Services II (MOPS II) tariff. The Company has received regulatory approval to
defer all costs incurred from implementing the MOPS and MOPS II pilot programs.
In each case, the Company may lose some margin. However, the Company experienced
a margin gain of $250,000 in 1998, due to electric market prices.

Direct Access and Delivery Service Tariff (DADS) To proactively respond to the
potential regulatory change of customer choice in the electric business, the
Company filed the DADS tariff to better understand how customer choice could
affect the Company and its large industrial customers. The Company concluded its
Direct Access and Delivery Service pilot (DADS-Schedule 26) in August 1998,
which was one of the first open-access pilots in the U.S. The pilot was a
two-year experiment that allowed twenty-six of the Company's largest customers
to purchase up to one-third of their energy requirements from an energy supplier
other than Avista Corp. Ten of the fifteen eligible Washington customers and
five of the eleven eligible Idaho customers participated in the pilot. The
Company agreed to absorb any of the resulting lost margin on the commodity no
longer supplied by the Company. The pilot provided useful information to the
company, participants, suppliers and other interested parties. As echoed in the
responses to the customer surveys, even many of the Company's largest customers
are not ready to embrace an open-access environment because of concerns
regarding reliability and potential price volatility.

More Options for Power Services (MOPS) A MOPS experimental tariff was filed in
February 1997 with the WUTC and IPUC to help the Company assess the potential
benefits of direct access for its electric residential and commercial customers
and to collect information that will assist in the transition to customer choice
for those classes of customers. The pilot allows only the customers in the towns
of Odessa and Harrington, Washington to participate. This trial tariff is
effective through June 30, 1999. Since its implementation date of July 1, 1997,
25% of the 980 eligible customers have elected Grant County PUD as their
supplier. This represents a bill savings of approximately 6% - 10% to customers.
Originally, six power marketers signed up to participate; all but Grant County
PUD withdrew upon California's announcement of full direct access by January 1,
1998.




19
24
AVISTA CORPORATION
- --------------------------------------------------------------------------------

More Options for Power Services II (MOPS II) While MOPS allowed customers to
purchase from alternative energy suppliers, MOPS II provides access to the
Company's portfolio of traditional service, monthly market, annual market and
renewable resource pricing. (See PA Model above for additional information.)
Approximately 7,300 customers in the towns of Deer Park, Washington and Hayden,
Idaho were able to elect alternative energy service from the Company as of July
1998. The Company received approval on this program on December 31, 1997 and
January 27, 1998 from the WUTC and IPUC, respectively. This trial tariff is
effective through mid-2000.

Avista Utilities' average production cost for a Washington residential customer
is 2.37 cents/kWh. For customers to save money under MOPS II, the average
monthly or annual market prices would need to be below this rate. During the
first eight months of MOPS II implementation, electric market rates were above
Avista Utilities' average retail rate in every month except February 1999. Thus,
participation in the annual and monthly market options has been low, with only
69 customers. Participation in the renewable resource offerings was also low.

ENVIRONMENTAL ISSUES

The Company is subject to environmental regulation by federal, state and local
authorities. The generation, transmission, distribution, service and storage
facilities in which the Company has an ownership interest have been designed to
comply with all environmental laws presently applicable. Furthermore, the
Company conducts periodic reviews of all its facilities and operations to
anticipate emerging environmental issues. The Company's Board of Directors has
an Environmental Committee to deal specifically with these issues.

Air Quality. The Company continues to assess both the potential and actual
impact of the 1990 Clean Air Act Amendments (CAAA) on the thermal generating
plants in which it maintains an ownership interest. Centralia, which is
operated by PacifiCorp, is classified as a "Phase II" coal-fired plant under
the CAAA and, as such, will be required to reduce sulfur dioxide (SO2)
emissions. Centralia is also impacted by "visibility impairment" issues related
to Mt. Rainier National Park in southwestern Washington, which requires
additional reductions in emissions. A RACT (Reasonably Available Control
Technology) order was issued by SWAPCA (Southwest Washington Air Pollution
Control Agency) which requires a reduction in SO2 emissions of approximately
90% by the year 2000. The standards in the RACT order were established by a
collaborative decision-making group consisting of representatives from federal
and state agencies and the plant owners. The owners of the Centralia project
have collectively offered the plant for sale through an auction process. Bids
are being accepted until April 19, 1999. Should the owners not accept any bid,
the remaining options include bringing the units into compliance with
provisions of the CAAA through adding scrubbers or some other SO2 removal
process. Plant closure will be another option if economics prove it to be a
viable option. The Company's estimated share of this option would be incurred
over several years and is currently estimated to be $35 million of capital
costs. These estimates of future obligations are included in the projected
Total Company Cash Requirements in Item 7. Management's Discussion and Analysis
of Financial Condition and Results of Operations: Liquidity.

Colstrip, which is also a "Phase II" coal-fired plant and is operated by Montana
Power, is not expected to be required to implement any additional SO2 mitigation
in the foreseeable future in order to continue operations. Reduction in nitrogen
oxides (NOX) will be required at both Centralia and Colstrip prior to the year
2000. The anticipated share of costs for NOX compliance are not expected to have
a major economic impact on the Company.

The Company's other thermal projects also are subject to various CAAA standards.
Every five years each project requires an updated operating permit (known as a
Title V permit) which addresses, among other things, the compliance of the plant
with the CAAA. The permit for the Spokane CTs was received in 1995. The permit
for the Company's Kettle Falls plant was issued in 1996. The operating permit
application for the Rathdrum CTs in northern Idaho received approval and was
issued in 1997.

ITEM 2. PROPERTIES

ENERGY DELIVERY

Electric Distribution and Transmission Plant

The Company operates approximately 12,200 miles of primary and secondary
distribution lines in its electric system in addition to a transmission system
of approximately 550 miles of 230 kV line and 1,550 miles of 115 kV line. The
Company also owns a 10% interest in 495 miles of a 500 kV line between Colstrip,
Montana and Townsend, Montana, and a 15% interest in three miles of a 500 kV
line from Centralia, Washington to the nearest Bonneville Power Administration
(Bonneville) interconnection.

The 230 kV lines are used to transmit power from the Company's Noxon Rapids and
Cabinet Gorge hydroelectric generating stations to major load centers in the
Company's service area as well as to transfer power between points of
interconnection with adjoining electric transmission systems. These lines
interconnect with Bonneville at five locations and at one location each with
PacifiCorp, Montana Power and Idaho Power Company. The Bonneville
interconnections serve as points of delivery for power from the Colstrip and
Centralia generating stations as well as for the interchange of power with
entities outside the Pacific Northwest. The interconnection with PacifiCorp is
used to integrate Mid-Columbia hydroelectric generating facilities to the
Company's loads as well as for the interchange of power with entities within the
Pacific Northwest.

The 115 kV lines provide for transmission of energy as well as providing for the
integration of the Spokane River hydroelectric and Kettle Falls wood-waste
generating stations with service area load centers. These lines interconnect
with Bonneville at nine locations, Grant County Public Utility District (PUD),
Seattle City Light and Tacoma City Light at two locations and one
interconnection each with Chelan County PUD, PacifiCorp and Montana Power.

Natural Gas Plant

The Company has natural gas distribution mains of approximately 3,897 miles in
Washington and Idaho and 1,755 miles in Oregon and California, as of December
31, 1998.

The Company, NWP and Puget Sound Energy each own a one-third undivided interest
in the Storage Project, which has a total peak day deliverability of 5.7 million
therms, with a total working natural gas inventory of 155.2 million therms.

damages against Underwriters at Lloyds of London (Lloyds) in Spokane County
Superior Court. The purpose of this action was to seek a declaration of the
insurance policies issued to the Company by Lloyds with respect to any
liabilities of the Company for environmental damage associated with the oil
spill at the Central Steam Plant and other environmental remediation efforts.
The policies at issue were in effect during the period between 1926 and 1966;
thereafter, the Company maintained its policies with another underwriter, Aegis.
The Company's Complaint sought money damages in excess of $16 million. On March
10, 1999, Avista Corp. and Lloyds signed a settlement agreement resolving the
claim.

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

Avista Corporation (Avista Corp. or the Company), formerly The Washington Water
Power Company, operates as a regional utility providing electric and natural gas
sales and services and as a national entity providing both energy and non-energy
products and services. The utility portion of the Company, doing business as
Avista Utilities, consists of two lines of business which are subject to state
and federal price regulation -- (1) Energy Delivery and (2) Generation and
Resources. The national businesses are conducted under Avista Capital, which is
the parent company to the Company's subsidiaries.

The Energy Delivery line of business includes transmission and distribution
services for retail electric operations, all utility natural gas operations, and
other energy products and services. Costs associated with electric energy
commodities, such as purchased power expense, as well as the revenues
attributable to the recovery of such costs from retail customers, have been
eliminated from the Energy Delivery line of business and are reflected in the
results of the Generation and Resources line of business. The results of all
natural gas operations are included in the Energy Delivery line of business
because natural gas trackers allow natural gas costs to pass through within this
line of business without the commodity prices having a material income effect.
Usage by retail customers varies from year to year primarily as a result of
weather conditions, customer growth and the economy in the Company's service
area. Other factors which may influence long-term energy usage include
conservation efforts, appliance efficiency and other technology.

The Generation and Resources line of business includes the generation and
production of electric energy, and short- and long-term electric and natural gas
sales trading and wholesale marketing, primarily to other utilities and power
brokers in the Western Systems Coordinating Council (WSCC). Energy trading
includes short-term sales and purchases, such as next hour, next day and monthly
blocks of energy. Wholesale marketing includes sales and purchases under
long-term contracts with one-year and longer terms. Generation and Resources
manages the Company's electric energy resource portfolio, which is used to serve
Energy Delivery's retail electric customers and Generation and Resources'
wholesale electric customers. In managing the electric energy resource
portfolio, Generation and Resources seeks to optimize the availability and
operations of generation resources. Revenues and the cost of electric power
purchases vary from year to year depending on the electric wholesale power
market, which is affected by several factors, including the availability of
water for hydroelectric generation, the availability of base load plants in the
region, marginal fuel prices and the demand for power in other areas of the
country. Other factors affecting the wholesale power market include lower unit
margins on new sales contracts than were realized in the past, fewer long-term
power contracts being entered into, deregulation of the electric utility
industry and competition from low cost generation being developed by independent
power producers.

Avista Capital is the parent company to the National Energy Trading and
Marketing and Non-energy businesses. In order to proactively respond to
deregulation, the Company created the National Energy Trading and Marketing line
of business, which is comprised of Avista Energy, Avista Advantage and Avista
Power. Avista Energy focuses on commodity trading, energy marketing and other
related businesses on a national basis, which includes conducting business
within the WSCC. Avista Energy's business is affected by several factors,
including the demand for and availability of power throughout the United States,
lower unit margins on new sales contracts, fewer long-term power contracts being
entered into, marginal fuel prices and deregulation of the electric utility
industry. Avista Advantage provides a variety of energy-related products and
services to commercial and industrial customers on a national basis. Its primary
product lines include consolidated billing, resource accounting, energy analysis
and load profiling. Avista Power was formed in December 1998 to develop and own
generation assets primarily in support of Avista Energy. See Liquidity and
Capital Resources: Energy Trading Business and Risk Management.

The Non-energy business is conducted primarily by Pentzer Corporation (Pentzer),
which is the parent company to the majority of the Company's Non-energy
businesses. Pentzer's business strategy is such that its earnings result from
both transactional and non-transactional earnings. Transactional gains arise
from a one-time event or a specific transaction, such as the sale of an
investment or individual company from Pentzer's portfolio of investments.
Non-transactional earnings arise out of the ongoing operations of the individual
portfolio companies.

Changes underway in the utility and energy industries are creating new
opportunities to expand the Company's businesses and serve new markets. In
pursuing such opportunities, the Company is shifting its strategic direction to
growth in order to achieve its goal of becoming a diversified North American
energy company.

RESULTS OF OPERATIONS

OVERALL OPERATIONS

1998 COMPARED TO 1997

Overall reported earnings per share for 1998 were $1.28, compared to $1.96 in
1997. The primary factors causing the decrease from 1997 were an income tax
recovery, net of associated items, which increased 1997 earnings per share by
$0.49, and decreased operating income from the Generation and Resources line of
business in 1998. In addition, in December 1998, the Company exchanged
15,404,595 shares of its common stock for shares of




26
31
AVISTA CORPORATION
- --------------------------------------------------------------------------------

Convertible Preferred Stock (see Notes 14 and 18 of Notes to Financial
Statements for additional information about the new Convertible Preferred Stock
and earnings per share). If these shares had been exchanged at the beginning of
the year, basic and diluted earnings per share for 1998 would have been $1.39
and $1.35, respectively.

Net income available for common stock decreased $39.7 million in 1998 from 1997.
The 1998 results primarily reflect hydroelectric generation 21% lower than 1997
and increased purchased power prices and volumes, partially offset by improved
earnings at Avista Energy. In addition, the 1997 results include the impact of
$41.4 million, after-tax, in an income tax recovery from the Internal Revenue
Service, which was partially offset by $14.0 million, after-tax, in
environmental reserves and non-recurring adjustments (see below and Note 8 of
Notes to Financial Statements for additional information about the income tax
recovery). Excluding these items, utility (Energy Delivery and Generation and
Resources) income available for common stock decreased $20.2 million, or 30%, in
1998, contributing $0.88 to earnings per share in 1998, compared to $1.22 in
1997. National Energy Trading and Marketing income available for common stock
increased $9.6 million, contributing $0.22 to earnings per share in 1998 as
compared to $0.04 in 1997 when there were only 5 months of operations.
Non-energy operating income available for common stock decreased $1.8 million,
or 15%, in 1998 and contributed $0.18 to earnings per share in 1998, compared to
$0.21 in 1997. Transactional gains recorded by Pentzer totaled $4.3 million, or
$0.08 per share, and $7.3 million, or $0.13 per share, in 1998 and 1997,
respectively.

Interest expense increased $2.8 million in 1998, as compared to 1997, primarily
due to higher levels of outstanding debt during the year. During 1998, $84.0
million of long-term debt was issued, while $14.0 million of long-term debt
matured or was redeemed. At December 31, 1998, there was no short-term debt
outstanding, compared to $108.5 million at December 31, 1997. Long-term debt
outstanding at December 31, 1998 was $32.2 million lower than at the end of
1997.

Income taxes decreased $17.7 million, or 29%, in 1998 from 1997, primarily due
to higher taxes in 1997 on the interest income received as a part of the income
tax recovery, partially offset by adjustments related to revised estimates on
certain tax issues.

Preferred stock dividend requirements increased $3.0 million in 1998 over 1997
due to the exchange of shares of common stock for shares of $12.40 Convertible
Preferred Stock, Series L, which occurred in December 1998. This was partially
offset by the redemption of $10 million in Preferred Stock, Series I in June
1998.

1997 COMPARED TO 1996

Overall earnings per share for 1997 were $1.96, compared to $1.35 in 1996. The
1997 results include the receipt of $41.4 million, after-tax, in an income tax
recovery from the Internal Revenue Service, which was partially offset by
environmental reserves and non-recurring adjustments (see below and Note 8 of
Notes to Financial Statements for additional information about the income tax
recovery). The 1996 results reflect $11.1 million in after-tax operating
expenses related to storm damage on the electric distribution system and the
expensing of $10.3 million in after-tax non-operating costs related to the
terminated proposed merger between the Company and Sierra Pacific Resources (see
Note 22 of Notes to Financial Statements for additional information about the
merger termination). The 1996 results also reflect transactional gains totaling
$15.1 million recorded by Pentzer primarily as a result of the sale of property
by one of its subsidiary companies and the sale of stock in Itron, Inc. (Itron).
Excluding all of these unusual items, earnings per share in 1997 would have been
$1.47 as compared to $1.73 for 1996.

Net income available for common stock increased $33.9 million, or 45%, in 1997
over 1996. In 1997, the income tax recovery resulted in an increase of $0.74 in
earnings per share for 1997, which was offset by $0.25 per share in
environmental reserves and other miscellaneous non-recurring adjustments. The
ice storm (see below) and merger-related expenses resulted in decreases of $0.20
and $0.18, respectively, in earnings per share for 1996. Utility income
contributed $1.71 in 1997, compared to $0.97 in 1996. National Energy Trading
and Marketing income available for common stock increased $3.6 million in 1997,
contributing $0.04 to earnings per share in 1997 compared to a loss of $0.02 in
1996. Non-energy operating income available for common stock decreased $10.7
million, or 48%, in 1997 and contributed $0.20 to earnings per share in 1997 and
$0.40 in 1996. Transactional gains recorded by Pentzer totaled $7.3 million, or
$0.13 per share, in 1997, and $15.1 million, or $0.27, in 1996.

Interest expense increased $3.0 million in 1997, as compared to 1996, primarily
due to higher levels of outstanding debt and new Preferred Trust Securities
issued during the year. In 1997 and 1996, $70 million and $20 million,
respectively, in preferred stock was redeemed, which resulted in higher levels
of short-term borrowings. In addition, a total of $110 million in Preferred
Trust Securities were issued in January and June 1997, distributions on which
are included in interest expense. (See Note 15 of Notes to Financial Statements
and Liquidity and Capital Resources for additional information.) During 1997 and
1996, $51.5 million and $38.0 million, respectively, of long-term debt matured
or was redeemed, while $20.0 million in long-term debt was issued in 1997. At
December 31, 1997, there was $108.5 million of short-term debt outstanding,
compared to $85.0 million at December 31, 1996. Long-term debt outstanding at
December 31, 1997 was $2.3 million lower than at the end of 1996.

In June 1997, the Company received $81 million from the Internal Revenue Service
(IRS) to settle an income tax claim relating to its investment in the terminated
nuclear project 3 of the Washington Public Power Supply System (WNP3). The $81
million recovery included $34 million in income taxes the Company overpaid in
prior years plus



27
32
AVISTA CORPORATION
- --------------------------------------------------------------------------------

$47 million in accrued interest, which in total contributed $41.4 million, or
$0.74 per share, to net income. (See Note 8 of Notes to Financial Statements for
additional information about the income tax recovery.)

Income taxes increased $11.6 million, or 23%, in 1997 over 1996. The increased
taxes in 1997 were primarily due to the taxes on the interest income received as
a part of the income tax recovery, partially offset by an $11.4 million income
tax benefit associated with the income tax recovery and adjustments related to
revised estimates on certain tax issues.

Preferred stock dividend requirements decreased $2.6 million in 1997 from 1996
due to the redemption of $20 million in Preferred Stock, Series I in June 1997
and the redemption of the entire $50 million Flexible Auction Preferred Stock,
Series J in August 1997. These securities were redeemed with a portion of the
proceeds of the Preferred Trust Securities which were issued in January and June
1997. However, as described above, distributions on the Preferred Trust
Securities are accounted for in interest expense, not preferred dividends.

ENERGY DELIVERY

1998 COMPARED TO 1997

Energy Delivery's income from operations increased $3.2 million in 1998 over
1997 primarily due to increased revenues in 1998. Energy Delivery's operating
revenues increased $29.2 million, while operating expenses increased $26.0
million during 1998 as compared to 1997.

Total electric retail revenues increased $1.8 million in 1998 as compared to
1997, primarily as a result of increased commercial and industrial revenues,
partially offset by decreased revenues from residential customers. Total natural
gas revenues increased $27.4 million in 1998 over 1997, primarily due to a
combination of 4.4% customer growth, increased natural gas prices approved by
the Washington Utilities and Transportation Commission (WUTC), effective in
January 1998, and an increase in non-retail sales, partially offset by decreased
customer usage as a result of weather 13% warmer than normal in 1998 as compared
to 5% warmer than normal in 1997.

Natural gas purchased costs increased $15.3 million in 1998 due to increased
sales volumes as a result of customer growth and higher non-retail sales.
Administrative and general expenses increased $7.0 million due primarily to
executive changes, corporate name change expenses and incentives. Depreciation
and amortization increased $2.0 million due to higher amounts of
plant-in-service.

1997 COMPARED TO 1996

Energy Delivery's income from operations increased $24.3 million, or 27%, in
1997 over 1996 primarily due to $17.1 million in pre-tax expenses associated
with the storm damage on the Company's electric distribution system in 1996.
Energy Delivery's operating revenues increased $0.1 million, while expenses
decreased $24.2 million during 1997 as compared to 1996.

On November 19, 1996, the eastern Washington and northern Idaho region
experienced an ice storm that resulted in damage to the Company's electric
transmission and distribution system. The Company's service area was affected by
continuing snow and rain, which hampered the Company's efforts to restore
electric service to some customers until December 1, 1996. Initially, over
one-third, or 100,000, of the Company's retail electric customers were without
electric service. Repairing the damage to the Company's system cost
approximately $21.8 million, of which $17.1 million (pre-tax) was attributable
to operations and maintenance expenses, including labor and materials, for the
repair of damaged lines, transformers and other equipment. The remainder of the
cost represents capital expenditures to replace poles and other equipment
damaged beyond repair.

Total electric retail revenues increased $5.6 million in 1997 as compared to
1996, primarily as a result of increased transmission revenues, partially offset
by decreased revenues from retail electric customers. Transmission revenues
increased $7.6 million in 1997 over 1996 due to increased wholesale electric
sales. Electric retail revenues decreased $3.4 million, primarily due to
decreased industrial sales as a result of the DADS tariff and other adjustments,
partially offset by a 1.6% growth in retail customers during 1997. Total natural
gas revenues decreased $5.5 million in 1997 from 1996, primarily due to
decreased therm sales as a result of weather 5% warmer than normal in 1997,
compared to 9% colder than normal in 1996, and decreased natural gas prices,
partially offset by an increase in non-retail sales and 5.7% customer growth.

Operating and maintenance expenses decreased $21.4 million in 1997 from 1996
primarily due to the $17.1 million in expenses recorded in 1996 related to the
storm damage on the Company's electric distribution system. Natural gas
purchased expense decreased $2.7 million in 1997 from 1996 primarily due to
lower therm sales as a result of warmer weather.

GENERATION AND RESOURCES




28
33
AVISTA CORPORATION
- --------------------------------------------------------------------------------

1998 COMPARED TO 1997

Generation and Resources' income from operations decreased $38.4 million, or
59%, in 1998 from 1997. The decrease was due to hydroelectric generation 21%
lower than 1997, which resulted in increased purchased power costs due to both
increased prices and volumes. Generation and Resources' operating revenues and
expenses increased $128.4 million and $166.8 million, respectively, during 1998
as compared to 1997.

Generation and Resources' revenues increased 25% in 1998 over 1997, primarily
due to increased short-term sales; however, this was more than offset by
increased purchased power and fuel costs. Revenues from short-term sales
increased $163.2 million, while long-term revenues decreased $35.8 million in
1998 as compared to 1997. Total sales volumes during 1998 increased 17% over
1997. Short-term sales volumes increased 3.4 million mwhs, or 28%, while
long-term sales decreased 0.6 million mwhs.

Increased short-term sales volumes and prices 30% higher than the previous year
resulted in a $160.4 million, or 52%, increase in electric purchased power
expense in 1998 over 1997, which accounts for the majority of the increase in
Generation and Resources' operating expenses. Fuel costs increased $9.8 million
in 1998 compared to 1997 as a result of increased generation at the thermal
generating plants to meet the demand for energy.

1997 COMPARED TO 1996

Generation and Resources' income from operations decreased $19.6 million, or
23%, in 1997 from 1996. The decrease was due to an $11.8 million decrease from
the expiration of older sales contracts with higher margins, lower unit margins
on new sales contracts and higher transmission expenses due to increased sales.
Generation and Resources' operating revenues and expenses increased $92.6
million and $112.2 million, respectively, during 1997 as compared to 1996.
Results from this business segment included activities for the first seven
months of 1997 that as of August 1997 were conducted by Avista Energy.

Generation and Resources' revenues increased 22% in 1997 over 1996, primarily
due to increased short-term sales. Revenues from short-term sales increased
$99.8 million, while long-term revenues decreased $0.4 million in 1997 as
compared to 1996. Total sales volumes during 1997 increased 47% over 1996.
Short-term sales volumes increased 5.4 million mwhs, or 82%, while long-term
sales decreased 0.2 million mwhs.

Increased short-term sales resulted in a $119.4 million, or 63%, increase in
electric purchased power expense in 1997 over 1996. Fuel costs decreased $6.1
million in 1997 compared to 1996 as a result of economic dispatch of the thermal
generating plants.

NATIONAL ENERGY TRADING AND MARKETING

National Energy Trading and Marketing includes the results of Avista Energy, the
national energy marketing subsidiary, Avista Advantage, the energy services
subsidiary, and Avista Power, which was formed in December 1998 to develop and
own generation assets primarily in support of Avista Energy. Avista Power
operations had no impact on 1998 earnings. Although Avista Energy and Avista
Advantage began incurring start-up costs during 1996, Avista Energy only became
operational in July 1997 and began trading operations in August 1997. Year to
year results are not comparable since 1997 only represents five months of
operations. Avista Energy maintains a trading portfolio which it marks to fair
market value on a daily basis (mark-to-market accounting), and which may cause
earnings variability in the future.

1998 COMPARED TO 1997

National Energy Trading and Marketing's income available for common stock
increased $9.6 million over 1997, while income from operations increased $17.7
million in 1998 over 1997, primarily due to a full year of operations at Avista
Energy. This increase was partially offset by a loss from the energy services
business, due to customers and revenue streams that did not materialize as
expected and a longer than anticipated sales cycle. National Energy Trading and
Marketing's operating revenues and expenses increased $2.16 billion and $2.14
billion, respectively, during 1998 as compared to 1997 when the Company only had
five months of operations.

Avista Energy provided positive results in 1998 despite the price volatility
experienced in power markets in the Midwest and East during various periods of
the year. The company was well-positioned in its market, which allowed net gains
in its portfolio during periods of high volatility. Avista Energy expected high
volatility in Eastern electric markets in the summer of 1998 based on expected
demand and the high probability of a weather-related impact on energy prices. As
a result, Avista Energy established positions in anticipation of volatile market
swings, and in turn experienced positive earnings in its portfolio during this
period. However, there is no guarantee that positive results can or will always
be achieved. For additional information about market risk and credit risk, see
Liquidity and Capital Resources: Risk Management.

National Energy Trading and Marketing's total assets and liabilities increased
by approximately $739.9 million from December 31, 1997 to December 31, 1998.
This increase resulted primarily from the increased volume of



29
34
AVISTA CORPORATION
- --------------------------------------------------------------------------------

transactions, as well as the impact of the market's price volatility on forward
price curves, which increased the valuation of Avista Energy's mark-to-market
assets and liabilities.

1997 COMPARED TO 1996

National Energy Trading and Marketing's income from operations increased $4.0
million in 1997 over 1996. This increase was primarily due to Avista Energy
becoming operational, partially offset by continued start-up costs at both
Avista Energy and Avista Advantage and, for the energy services business,
customers and revenue streams that did not materialize as expected and a longer
than anticipated sales cycle. National Energy Trading and Marketing's operating
revenues and expenses increased $247.5 million and $243.5 million, respectively,
during 1997 as compared to 1996.

NON-ENERGY

1998 COMPARED TO 1997

Non-energy income available for common stock for 1998 was $9.8 million, which
was a $1.8 million decrease from 1997 earnings. Transactional gains decreased to
$4.3 million in 1998 from $7.3 million in 1997, while non-transactional earnings
from Pentzer's portfolio companies increased $2.2 million. The non-transactional
earnings included an approximate $4.4 million after-tax loss in the fourth
quarter at a Pentzer operating company due to a business repositioning and an
inventory adjustment.

Income from operations totaled $9.7 million, which was a $0.8 million increase
over 1997. Non-energy operating revenues and expenses increased $68.3 million
and $67.5 million, respectively, primarily as a result of acquisitions and
increased business activity from several of Pentzer's portfolio companies.

1997 COMPARED TO 1996

Non-energy net income for 1997 was $11.5 million, which represents a $10.7
million, or 48%, decrease from 1996. The decrease in 1997 earnings primarily
resulted from transactional gains recorded by Pentzer in 1997 totaling $7.3
million, from the sale of Itron stock and the sale of a portfolio company,
compared to transactional gains during 1996 totaling $15.1 million, net of taxes
and other adjustments, as a result of the sale of property by one of its
subsidiary companies and the sale of stock in Itron.

Operating income decreased $6.1 million in 1997 from 1996 primarily as a result
of lower earnings contributions from Pentzer portfolio companies. Non-energy
operating revenues and expenses increased $18.2 million and $24.2 million,
respectively, primarily as a result of acquisitions.

LIQUIDITY AND CAPITAL RESOURCES

Overall Operations

Operating Activities Cash from operating activities less cash dividends paid
provided all funds needed for capital expenditures in 1998, 1997 and 1996. Net
cash provided by operating activities in 1998 increased over 1997 due primarily
to the $143.4 million provided by the monetization of a contract (see below and
Note 1 of Notes to Financial Statements for additional information). In
addition, changes in various working capital components, such as receivables and
payables, caused cashflows to decrease by $44.6 million from 1997, primarily due
to the growth in Avista Energy's operations.

Investing Activities Net cash used in investing activities decreased in 1998
from 1997 primarily due to the sale of marketable securities held for investing
activities by Pentzer, compared to the sale of subsidiary assets by Pentzer in
1997. Utility operations' capital expenditures, excluding Allowance for Funds
Used During Construction (AFUDC) and Allowance for Funds Used to Conserve Energy
(AFUCE, a carrying charge similar to AFUDC for conservation-related capital
expenditures), were $268 million for the 1996-1998 period.

Financing Activities Net cash used in financing activities totaled $108.7
million in 1998 compared to $66.2 million in 1997. In 1998, $84.0 million of
proceeds were received from the issuance of Medium-Term Notes. These proceeds,
plus cash provided from operating activities, were used to retire $14.0 million
of long-term debt, redeem $10 million of preferred stock and pay down $108.5
million of short-term debt. In 1997, $110 million of preferred trust securities
were issued (see Note 15 of Notes to Financial Statements for additional
information), the proceeds of which, along with an additional $20.0 million from
the issuance of Secured Medium-Term Notes, were used for the maturity and
redemption of $70.0 million of preferred stock and $51.5 million of long-term
debt. During the 1996-1998 period, $203.5 million of long-term debt and
preferred stock matured, was mandatorily redeemed or was optionally redeemed and
refinanced at a lower cost.

During 1998, the Company entered into an agreement that increased the amount of
customer accounts receivable the Company could sell from $40 million to $80
million to provide additional funds for capital expenditures, maturing long-term
debt and preferred stock sinking fund requirements. At December 31, 1998, $25.0
million in receivables had been sold pursuant to the agreement.

In August 1998, the Company announced a dividend restructuring plan that reduced
the Company's annual common stock dividend from $1.24 per share to $0.48 per
share, a 61% reduction, which was effective with the payment of the common stock
dividend paid on December 15, 1998. At the same time, an exchange offer was made
whereby shareholders were provided the opportunity to exchange their shares of
common stock for mandatorily convertible preferred shares, each of which pays an
annual dividend of $1.24 per share for a period of about three years. After
three years, the new-issue preferred shares will automatically convert back to
common stock, based on the shares converted. The Company has the option of
converting some or all of the new-issue shares to common stock prior to the end
of the three-year period. Shareholders who chose not to participate in the
exchange plan retained their ownership in Avista Corporation common stock. The
annual savings resulting from the dividend restructuring are approximately $30
million for the next three years, increasing to about $42 million annually once
the convertible preferred shares are converted back to common stock, which will
assist in funding a portion of the Company's capital expenditures, maturing
long-term debt and preferred stock sinking fund requirements. See Note 14 of
Notes to Financial Statements for additional information about the new
convertible preferred stock.

ENERGY DELIVERY AND GENERATION AND RESOURCES OPERATIONS

The Company funds capital expenditures with a combination of
internally-generated cash and external financing. The level of cash generated
internally and the amount that is available for capital expenditures fluctuates
annually. Cash provided by operating activities remains the Company's primary
source of funds for operating needs, dividends and capital expenditures.

Capital expenditures are financed on an interim basis with notes payable (due
within one year). The Company has $200 million in committed lines of credit. In
addition, the Company may currently borrow up to $100 million through other
borrowing arrangements with banks. As of December 31, 1998, there were no
outstanding borrowings under the committed lines of credit or the other
short-term borrowing arrangements.

AVISTA CORPORATION
- -------------------------------------------------------------------------------

From time to time the Company enters into sale/leaseback arrangements for
various long-term assets which provide additional sources of funds. See Note 12
of Notes to Financial Statements for additional information.

In December 1998, the Company assigned and transferred certain rights under a
long-term power sales contract to a funding trust. In return, the Company
received approximately $143.4 million, representing the present value of the
cash flows for the majority of the remaining payments due under the long-term
sales contract. The Company utilized the funds to repay short-term bank
borrowings and other debt.

The Company is restricted under various agreements as to the additional
securities it can issue. Under the most restrictive test of the Company's
Mortgage, an additional $623 million of First Mortgage Bonds could be issued as
of December 31, 1998. As of December 31, 1998, under its Restated Articles of
Incorporation, approximately $715 million of additional preferred stock could be
issued at an assumed dividend rate of 6.95%.

During the 1999-2001 period, utility capital expenditures are expected to be
$283 million, and $127.5 million will be required for long-term debt maturities
and preferred stock sinking fund requirements. During this three-year period,
the Company estimates that internally-generated funds will provide approximately
80% of the funds needed for its capital expenditure program. External financing
will be required to fund a portion of capital expenditures, maturing long-term
debt and preferred stock sinking fund requirements. Sources of funds would
include, but are not necessarily limited to, cash flows from the reduction in
the Company's common stock dividend, sales of certain assets, additional
long-term debt, leasing or other equity securities. These estimates of capital
expenditures are subject to continuing review and adjustment. Actual capital
expenditures may vary from these estimates due to factors such as changes in
business conditions, construction schedules and environmental requirements.

See Notes 2, 10, 11, 12, 13, 14, 15, 16 and 17 of Notes to Financial Statements
for additional details related to financing activities.

NATIONAL ENERGY TRADING AND MARKETING OPERATIONS

During 1998, the Company invested $65.1 million in the common equity of Avista
Capital. Avista Capital utilized the majority of the proceeds from this
investment to increase its total investment in the common equity of Avista
Energy to $106.7 million. Avista Energy funds its ongoing operations with a
combination of internally-generated cash and external financing. The Company
expects continued significant growth in Avista Energy's national energy trading
and marketing business activities. This rapid growth will require increased
capital investment, as well as an increased need for credit and financial
support.

Effective December 23, 1998, Avista Energy arranged for an increase in its
credit facility with a commercial bank from $50 million to $100 million. The
credit agreement expires April 1, 1999. The facility provides capital resources
to accommodate growth, principally in the form of letters of credit used to
enhance credit for natural gas and electricity purchases. The credit facility
also provides Avista Energy liquidity in the form of short-term borrowings used
to finance inventory and receivables. The maximum cash component of credit
extended by the bank is $30 million, with availability of up to $100 million in
the issuance of letters of credit. The credit agreement may be terminated by the
bank at any time and all extension of credit under the agreement are payable
upon demand, in either case at the bank's sole discretion. The facility is
guaranteed by Avista Capital and is secured by substantially all of Avista
Energy's assets. At December 31, 1998 and 1997, there were no cash advances
(demand notes payable) outstanding. Letters of credit outstanding under the
facility totaled approximately $20.2 million and $2.8 million at December 31,
1998 and 1997, respectively. See Note 11 of Notes to Financial Statements for
additional information.

At December 31, 1998, the National Energy Trading and Marketing operations had
$38.0 million in cash and cash equivalents and $0.9 million in long-term debt
outstanding.

The 1999-2001 National Energy Trading and Marketing capital expenditures are
expected to be $10.1 million.

NON-ENERGY OPERATIONS

Capital expenditures for the non-energy operations were $28.0 million for the
1996-1998 period. During this period, $45.5 million of debt was repaid and
capital expenditures were partially financed by the $62.6 million in proceeds
from new long-term debt.



32
37

AVISTA CORPORATION
- -------------------------------------------------------------------------------

The non-energy operations have $54.0 million in short-term borrowing
arrangements ($21.4 million outstanding as of December 31, 1998) to fund
corporate requirements on an interim basis. At December 31, 1998, the non-energy
operations had $18.0 million in cash and marketable securities with $54.0
million in long-term debt outstanding.

The 1999-2001 non-energy capital expenditures are expected to be $17.8 million,
and $32.3 million in debt maturities will also occur. During the next three
years, internally-generated cash and other debt obligations are expected to
provide the majority of the funds for the non-energy capital expenditure
requirements.

Avista Labs, a subsidiary of Avista Capital, recently announced the receipt of a
$2 million technology development award from the Department of Commerce's
National Institute of Standards and Technology Advanced Technology Program. The
Company will contribute another $1.22 million over a two-year period. Avista
Labs plans to work on technology that will increase the energy density of its
fuel cell design and develop multiple fuel processing approaches using propane,
methane and methanol as base fuels to integrate into its fuel cell subsystem.

The Company's total common equity decreased $260.8 million to $488.0 million at
the end of 1998. The 1998 decrease was primarily due to the exchange of shares
of common stock for shares of $12.40 Convertible Preferred Stock, Series L (see
Note 14 of Notes to Financial Statements for additional information). The
Company's consolidated capital structure at December 31, 1998, was 45% debt, 25%
preferred securities (including the Preferred Trust Securities) and 30% common
equity as compared to 46% debt, 9% preferred securities (including the Preferred
Trust Securities) and 45% common equity at year-end 1997. Had the convertible
preferred stock been converted back to common stock, the Company's consolidated
capital structure at December 31, 1998, would have been 45% debt, 9% preferred
securities (including the Preferred Trust Securities) and 46% common equity.

ADDITIONAL FINANCIAL DATA

At December 31, 1998, the total long-term debt of the Company and its
consolidated subsidiaries, as shown in the Company's consolidated financial
statements, was approximately $730.0 million. Of such amount, $237.5 million
represents long-term unsecured and unsubordinated indebtedness of the Company,
and $449.3 million represents secured indebtedness of the Company. The balance
of $43.2 million represents indebtedness of the subsidiaries. Consolidated
long-term debt does not include the Company's subordinated indebtedness held by
the issuers of Company-obligated preferred trust securities.

FUTURE OUTLOOK

Business Strategy

Changes underway in the utility and energy industries are creating new
opportunities to expand the Company's businesses and serve new markets. In
pursuing such opportunities, the Company is shifting its strategic direction to
growth in order to achieve its goal of becoming a diversified North American
energy company.



33
38

AVISTA CORPORATION
- -------------------------------------------------------------------------------

The Company's growth strategy will expose the Company to risks associated with
rapid expansion, challenges in recruiting and retaining qualified personnel,
risks associated with acquisitions and joint ventures and increasing
competition. In addition, growth in the energy trading and marketing business
will expose the Company to increased financial and credit risks associated with
commodity trading activities. The Company believes that its extensive experience
in the electric and natural gas business, coupled with its strong management
team, will allow the Company to effectively manage its transition to a
diversified North American energy company.

Energy

The Company seeks to strengthen its position of leadership in energy delivery
and generation as well as energy trading and marketing on a local, regional and
national basis. The Company will seek to increase its asset and customer base
through a focus on acquisitions and strategic alliances in all parts of its
business. The Company intends to focus on growing its core energy business by
seeking to acquire control of physical assets, specifically power generation
assets and electric and natural gas transmission and distribution assets. The
Company expects that initial growth will come at a local and regional level,
with national growth to follow. Key strengths of the Company today include its
position as one of the lowest cost producers of power in the nation, expertise
in hydroelectric and power system management, plus capabilities in trading and
wholesale and retail marketing of natural gas and electric energy. The Company
is also continuing to develop a unique approach to commercialization of fuel
cell technology.

Locally. The Company is a long-standing leader in the Northwest region of the
United States, providing some of the lowest cost energy to its customers. The
Company's strategy is to add selectively to its already strong foundation of
state-regulated utility assets to solidify its position as a leading supplier of
low-cost electric and natural gas energy services.

Regionally. The Company intends to add to its regulated and non-regulated assets
on a regional basis and participate in industry consolidation to further
optimize its assets and create greater economies of scale. In addition to energy
delivery and generation, the Company plans to concentrate on growing its energy
trading and marketing business. The strong growth in this business is driven by
the Company's significant base of knowledge and experience in the operation of
physical systems - for both natural gas and electric energy in the region, as
well as its relationship-focused approach to the customer. The Company will also
focus on expanding its telecommunications business through its newest
subsidiary, Avista Communications. (See Note 21 of Notes to Financial Statements
for additional information about this subsidiary.)

Nationally. The Company's strong regional energy trading and marketing skills
serve as a platform for the Company's growing national presence. The Company
will seek to expand its customer base through relationships with other energy
providers outside the Company's Northwest stronghold, thereby leveraging its
existing trading and marketing skills, as well as through its Internet-based
specialty billing and information services.

Non-Energy

The Company conducts the majority of its non-energy business through Pentzer,
its wholly owned subsidiary. Pentzer's business strategy is to acquire
controlling interests in a broad range of middle market companies, facilitate
improved productivity and growth, and ultimately sell such companies to the
public or a strategic buyer.

Competition and Business Risk

The Company continues to compete for new retail electric customers with various
rural electric cooperatives and public utility districts in and adjacent to its
service territories. Challenges facing the retail electric business include
evolving technologies that provide alternate energy supplies, the cost of the
energy supplied, the potential for retail wheeling, self-generation and fuel
switching by commercial and industrial customers and increasingly stringent
environmental laws. When electric utility companies are required to provide
retail wheeling service, the Company believes it will be in a position to
benefit since it is committed to remaining one of the country's lowest-cost
providers of electric energy. Consequently, the Company believes it faces
minimal risk for stranded generation, transmission or distribution assets due to
its low cost structure. The Company's need for new future electric resources to
serve retail loads is expected to remain very minimal.

Natural gas remains priced competitively compared to other alternative fuel
sources for residential, commercial and industrial customers and is projected to
remain so into the future due to abundant supplies and competition. Challenges
facing the Company's retail natural gas business include the potential for
customers to by-pass the Company's natural gas system. To reduce the potential
for such by-pass, the Company prices its natural gas services,



34
39

AVISTA CORPORATION
- -------------------------------------------------------------------------------

including transportation contracts, competitively and has varying degrees of
flexibility to price its transportation and delivery rates by means of special
contracts. The Company has long-term transportation contracts with seven of its
largest industrial customers which reduces the risks of these customers
by-passing the Company's system in the foreseeable future.

Generation and Resources and Avista Energy continue to compete in the wholesale
electric market with other utilities, federal marketing agencies and power
marketers. It is expected that competition to sell capacity will remain
vigorous, and that prices will remain depressed for at least the next several
years, due to increased competition and surplus capacity in the western United
States. Competition related to the sale of capacity and energy is influenced by
many factors, including the availability of capacity in the western United
States, the availability and prices of natural gas and oil, spot energy prices
and transmission access. Business challenges affecting the Generation and
Resources and National Energy Trading and Marketing lines of business include
competition from low-cost generation being developed by independent power
producers, declining margins due to a greater reliance on short-term sales,
evolving technologies that provide alternate energy supplies and deregulation of
electric and natural gas markets.

The Company's energy-related businesses are exposed to risks relating to changes
in certain commodity prices and counterparty performance. In order to manage the
various risks relating to these exposures, the Company utilizes electric,
natural gas and related commodity derivatives, and has established risk
management oversight for these risks for each area of the Company's
energy-related business. The Company has implemented procedures to manage such
risk and has established a comprehensive Risk Management Committee, separate
from the units that create such risk exposure and overseen by the Audit and
Finance Committee of the Company's Board of Directors, to monitor compliance
with the Company's risk management policies and procedures.

Economic and Load Growth

The Company expects economic growth to continue in its eastern Washington and
northern Idaho service area. The Company, along with others in the service area,
is continuing its efforts to facilitate expansion of existing businesses and
attract new businesses to the Inland Northwest. Agriculture, mining and lumber
were the primary industries for many years, but health care, education,
electronic and other manufacturing, tourism and the service sectors have become
increasingly important industries that operate in the Company's service area.
The Company also anticipates moderate economic growth to continue in its Oregon
service area.

The Company anticipates residential and commercial electric load growth to
average approximately 2.3% annually for the next five years primarily due to
increases in both population and the number of businesses in its service
territory. The number of electric customers is expected to increase and the
average annual usage by residential customers is expected to remain steady on a
weather-adjusted basis. A Public Utility Regulatory Policies Act of 1978 (PURPA)
contract with the Company's largest customer expires in 2002. The customer is
expected to self-generate at that time, which will reduce the load to this
customer by the amount the Company has been purchasing and then reselling to
them. Although it will have no material impact on loads, it will reduce the
Company's costs since the PURPA contract is at above-market prices. Overall, the
load growth, adjusted for this situation, is 2.4% annually.

The Company anticipates natural gas load growth, including transportation
volumes, in its Washington and Idaho service area to average approximately 2.7%
annually for the next five years. The Oregon and South Lake Tahoe, California
service areas are anticipated to realize 3.1% growth annually during that same
period.

The forward-looking projections set forth above regarding retail sales growth
are based, in part, upon publicly available population and demographic studies
conducted independently. The Company's expectations regarding retail sales
growth are also based upon various assumptions including, without limitation,
assumptions relating to weather and economic and competitive conditions and an
assumption that the Company will incur no material loss of retail customers due
to self-generation or retail wheeling. Changes in the underlying assumptions can
cause actual experience to vary significantly from forward-looking projections.

Environmental Issues

Since December 1991, a number of species of fish in the Northwest, including the
Snake River sockeye salmon and chinook salmon, the Kootenai River white
sturgeon, the upper Columbia River steelhead and the bull trout have been listed
as threatened or endangered under the Federal Endangered Species Act (ESA). A
listing of the upper Columbia River spring chinook is anticipated by mid-1999.
Thus far, measures which have been adopted and implemented to save the Snake
River sockeye salmon and chinook salmon have not directly impacted generation
levels at any of the



35
40

AVISTA CORPORATION
- -------------------------------------------------------------------------------

Company's hydroelectric dams. The Company does, however, purchase power from
four projects on the Columbia River that are being directly impacted by ongoing
mitigation measures for spring chinook, salmon and steelhead. The reduction in
generation at these projects is relatively minor, resulting in minimal economic
impact on the Company at this time. It is currently not possible to accurately
predict the likely economic costs to the Company resulting from all future
actions.

The Company is currently in the process of relicensing the Cabinet Gorge and
Noxon Rapids hydroelectric projects on the Clark Fork River in northern Idaho
and western Montana. The restoration of native salmonid fish, in particular bull
trout, is a principal focus for the members of the collaborative relicensing
team. Bull trout are native to this area and a "threatened" listing for bull
trout occurred in 1998 under the ESA. The Company is working closely with the
U.S. Fish and Wildlife Service, Native American tribes and the states of Idaho
and Montana to institute coordinated recovery measures on the lower Clark Fork
River. A settlement agreement reached in conjunction with the filing in February
1999 for new FERC licenses establishes a plan for bull trout restoration,
including annual budget estimates.

Relicensing studies in 1997 and 1998 indicated very high levels of atmospheric
gas supersaturation below Cabinet Gorge Dam during periods of heavy spill. The
settlement agreement provides for additional studies to identify what, if any,
effects there are to aqueous resources and whether abatement measures, and what
type, will be required at Cabinet Gorge.

See Note 20 of Notes to Financial Statements for additional information.

YEAR 2000

The Company continues to move forward with a comprehensive program to address
areas of risk associated with the Year 2000. Systems and programs that may be
affected by the Year 2000 problem have been identified and activities are
underway to make these systems Year 2000 ready. At this time, it is the
Company's belief that all identified modifications that are within the Company's
operating control will be made within the required time frames.

State of Readiness

In order to address Year 2000 issues, several project activity teams were
created and a comprehensive readiness plan was developed to bring the Company's
business critical systems into Year 2000 readiness by the middle of 1999. The
Company defines business critical systems as systems that directly affect the
Company's ability to deliver energy services to customers. The Company's Year
2000 project was originally divided into four major categories of activities:
Desktop Computer Systems, Business Systems, Supply Chain and Embedded Systems.
Contingency Planning developed into its own category in late 1998.

Desktop Computer Systems All desktop computer hardware has been Year 2000 tested
and an inventory and assessment of desktop resident third-party software has
been completed. The Company expects hardware remediation to be completed by
mid-1999. All non-compliant third-party software programs and critical business
desktop applications are expected to be upgraded, converted, tested and made
Year 2000 ready by the middle of 1999.

Business Systems Many of the Company's critical business systems would not have
operated correctly in the year 2000 and beyond, and thus have been or are in the
process of being re-programmed, upgraded or replaced. Key business systems have
been inventoried and assessed. The Company has completed remediating all
mainframe computer code that required fixing to address the Year 2000 issue and
testing has been completed on all but two of the Company's mainframe computer
business systems. Testing of the two remaining mainframe business systems is
scheduled to be completed before the end of April 1999. Implementation of a new
Materials Management system is scheduled for late 1999. The Company is in the
process of developing alternative plans in the unlikely event the Company is
unable to implement the new Materials Management System before the year 2000. A
failure of these systems would not jeopardize the Company's ability to deliver
energy services to customers, but might affect its ability to perform selected
accounting and business-related functions. The Company has completed testing and
remediation of approximately 85% of its business critical systems.

Supply Chain The Company recognizes its dependence on outside suppliers of goods
and services and is working to assure that the necessary products and services
are available. To address these issues, the Company has communicated with
suppliers and identified critical suppliers in order to investigate their
efforts to become Year 2000 ready. In addition, the Company has made site visits
to select key suppliers and will be reviewing their contingency plans.



36
41

AVISTA CORPORATION
- -------------------------------------------------------------------------------

Embedded Systems The Embedded System team is responsible for locating,
assessing, testing, fixing or replacing microprocessor-controlled devices.
Inventory and assessment is 99 percent complete, and to date very few embedded
systems have been found that require remediation. None of these requiring
remediation would have caused a disruption in service to customers. Remediation
and testing is complete at all eleven of the Company's generation sites and
these sites are Year 2000 ready.

The Company's Supervisory Control and Data Acquisition (SCADA) system, which
monitors and controls the majority of the Company's generating and substation
equipment and the transmission system, was run "in the Year 2000" for three days
without incident. Testing of electric metering and devices in the Company's
transmission and distribution substations systems has been completed and full
testing of selected substations is in process and scheduled to be completed by
mid-1999.

Contingency Planning

The Company has developed contingency plans for the Company's electric and
natural gas services and has also participated in the development of region-wide
contingency plans for electric service through the Company's electric
reliability region - the Western Systems Coordinating Council (WSCC).

A major Year 2000 project activity for the Company during 1999 will be the
development and implementation of detailed operational plans to support the
Company's contingency plans. Key activities in 1999 include the assignment of
resources to key locations for the evening of December 31, 1999 and the morning
of January 1, 2000, training of personnel, testing of backup procedures and the
completion of tasks that support the Company's contingency plans. The Company
will continue to participate in the further development and testing of the
region-wide contingency plans. This includes region-wide drills coordinated by
the WSCC scheduled for April 9, 1999 and September 9, 1999.

Costs

The Company estimates that the cost of its Year 2000 project will be
approximately $6-7 million in incremental costs during the 1997-1999 time
period. Through December 31, 1998, the Company has spent $3.5 million in
incremental costs. These costs are being funded through operating cashflows. The
Company does not expect costs associated with the Year 2000 project to
materially affect the Company's earnings in any one year.

Risks

Based upon information to date, the Company believes that, in the most
reasonably likely worst-case scenario, Year 2000 issues could result in abnormal
operating conditions, such as short-term interruption of generation,
transmission and distribution functions, as well as Company-wide loss of system
monitoring and control functions and loss of voice communications. These
conditions, along with disruptions in natural gas service caused by failures of
gas suppliers or interstate gas pipelines coupled with power outages due to the
possible instability of the regional electric transmission grid, could result in
the possible temporary interruption of service to customers. The Company does
not believe the overall impact of this scenario will have a material impact on
its financial condition or operations due to the anticipated short-term nature
of interruptions.

The Company believes the primary areas of Year 2000 risk to be internal business
systems, which are discussed above, and external factors, which include the
regional electric transmission grid and natural gas pipelines. There can be no
guarantee that systems of other companies on which the Company's systems rely
will be timely converted. A failure to convert by another company or a
conversion that is incompatible with the Company's systems could have an effect
on the Company's ability to provide energy services.

Electric The Company is working with the other energy suppliers in the area to
address risks related to the regional electric transmission grid, which consists
of the interconnected transmission systems of each utility within the WSCC. Such
interconnected systems are critical to the reliability of each interconnected
electric service provider, as the failure of one such interconnected provider to
achieve Year 2000 compliance could disrupt the others from providing electric
services. Should the regional electric transmission grid become unstable, power
outages may occur. The Company cannot assure Year 2000 compliance or assess the
effect of non-compliance by systems or parties that the Company does not
control.

In addition to the traditional electric utility operations of the Company, the
energy trading business conducted by Avista Energy is subject to Year 2000 risk.
Most of Avista Energy's internal business systems do not require any




37
42

AVISTA CORPORATION
- -------------------------------------------------------------------------------

significant upgrading and those that do are being addressed. However, if any of
Avista Energy's counterparties experience Year 2000 problems (including, but not
limited to, problems arising out of failures in the generation or transmission
systems of utilities or other energy suppliers), such problems could impair the
ability of Avista Energy or any of its counterparties to fulfill their
contractual obligations. Avista Energy is in the process of contacting its
counterparties to assess their Year 2000 readiness and of developing contingency
plans. See "Energy Trading Business".

Natural Gas The Company has performed an inventory and assessment of the
equipment in its natural gas distribution systems and believes that there are no
devices in the systems that will cause a disruption in the delivery of natural
gas to customers due to a Year 2000 problem. However, the Company depends on
natural gas pipelines which it does not own or control, and if one or more of
the pipelines is unable to deliver natural gas, the Company in turn will be
unable to deliver natural gas to customers. In order to address this issue, the
Company has contacted each of the natural gas pipeline companies with which it
has contracts to assess their Year 2000 readiness efforts and will continue to
take reasonable steps to ensure that these suppliers are addressing any Year
2000 related problems that would result in a disruption in natural gas services
to customers.

ENERGY TRADING BUSINESS

The participants in the emerging wholesale energy market are public utility
companies and, increasingly, power marketers which may or may not be affiliated
with public utility companies or other entities. The participants in this market
trade not only electricity and natural gas as commodities but also derivative
commodity instruments such as futures, forwards, swaps, options and other
instruments. This market is largely unregulated and most transactions are
conducted on an "over-the-counter" basis, there being no central clearing
mechanism (except in the case of specific instruments traded on the commodity
exchanges). Power marketers, whether or not affiliated with other entities,
generally do not own production facilities and are not subject to net capital or
other requirements of any regulatory agency.

The Company (to the extent that the Generation and Resources segment conducts
energy trading) and Avista Energy are subject to the various risks inherent in
commodity trading including, particularly, market risk and credit risk.

Market risk is, in general, the risk of fluctuation in the market price of the
commodity being traded and is influenced primarily by supply (in the case of
electricity, adequacy of generating reserve margins as well as scheduled and
unscheduled outages of generating facilities) and demand (extreme variations in
the weather, whether or not predicted). Market risk includes the risk of
fluctuation in the market price of associated derivative commodity instruments.
All market risk is influenced to the extent that the performance or
non-performance by market participants of their contractual obligations and
commitments affect the supply of, or demand for, the commodity.

Credit risk relates to the risk of loss that the Company (to the extent of
Generation and Resources' trading activities) and/or Avista Energy would incur
as a result of non-performance by counterparties of their contractual
obligations under the various instruments with the Company or Avista Energy, as
the case may be. Credit risk may be concentrated to the extent that one or more
groups of counterparties have similar economic, industry or other
characteristics that would cause their ability to meet contractual obligations
to be similarly affected by changes in market or other conditions. In addition,
credit risk includes not only the risk that a counterparty may default due to
circumstances relating directly to it, but also the risk that a counterparty may
default due to circumstances which relate to other market participants which
have a direct or indirect relationship with such counterparty. The Company and
Avista Energy seek to mitigate credit risk (and concentrations thereof) by
applying specific eligibility criteria to prospective counterparties. However,
despite mitigation efforts, defaults by counterparties occur from time to time.
To date, no such default has had a material adverse effect on the Company or
Avista Energy.

Avista Capital provides guarantees for Avista Energy's line of credit agreement,
and in the course of business may provide guarantees to other parties with whom
Avista Energy may be doing business. The Company's investment in Avista Capital
totaled $271.8 million at December 31, 1998.

RISK MANAGEMENT

The risk management process established by the Company is designed to measure
both quantitative and qualitative risk in the business. The Company and Avista
Energy have adopted policies and procedures to manage the risks inherent in
their businesses and have established a comprehensive Risk Management Committee,
separate from the units that

AVISTA CORPORATION
- -------------------------------------------------------------------------------

create the risk exposure and overseen by the Audit and Finance Committee of the
Company's Board of Directors, to monitor compliance with the Company's risk
management policies and procedures on a regular basis. Nonetheless, adverse
changes in interest rates, commodity prices and foreign currency exchange rates
may result in losses in earnings, cash flow and/or fair values.

The forward-looking information presented below provides only estimates of what
may occur in the future, assuming certain adverse market conditions, due to
reliance on model assumptions. As a result, actual future results may differ
materially from those presented. These disclosures are not indicators of
expected future losses, but only indicators of reasonably possible losses.

Interest Rate Risk The Company is subject to the risk of fluctuating interest
rates in the normal course of business. The fair value of the Company's cash and
short-term investment portfolio and the fair value of notes payable at December
31, 1998 approximated carrying value. Given the short-term nature of these
instruments, market risk, as measured by the change in fair value resulting from
a hypothetical change in interest rates, is immaterial.

The Company manages interest rate risk by taking advantage of market conditions
when timing the issuance of long-term financings and optional debt redemptions
and through the use of fixed rate long-term debt with varying maturities. A
portion of the Company's capitalization consists of floating rate
Company-Obligated Mandatorily Redeemable Preferred Trust Securities, of which
the interest portion of the $50 million Series B resets on a quarterly basis,
reflecting current market conditions. As of December 31, 1998, a hypothetical
15% change in interest rates would result in an immaterial change in the
Company's cash flows related to the increased interest expense associated with
these floating rate securities.

Commodity Price Risk The Company and Avista Energy are exposed to market
fluctuations in the price and transportation costs of electric and natural gas
commodities and, therefore, enter into contracts to hedge the impact of these
fluctuations on their energy-related assets, liabilities, and other contractual
arrangements. In addition, Avista Energy enters into these contracts for trading
purposes to take advantage of market opportunities. At times this may create a
net open position in its portfolio that could result in material losses if
prices do not move in the manner or direction anticipated. The Company and
Avista Energy's risk management program and policies are designed to manage the
risks associated with market fluctuations in the price of electricity and
natural gas commodities (see Note 3 of Notes to Financial Statements for
additional information).

Avista Energy measures the risk in its derivative commodity portfolio on a
daily basis utilizing a Value-at-Risk (VAR) model and monitors its risk in
comparison to established thresholds. VAR measures the worst expected loss over
a given time interval under normal market conditions at a given confidence
level. The Company and Avista Energy also use other measures to monitor the risk
in their derivative commodity portfolios on a monthly, quarterly and annual
basis.

The VAR computations are based on an historical simulation, which utilizes price
movements over a specified period to simulate forward price curves in the energy
markets to estimate the unfavorable impact of one-day's price movement in the
existing portfolio. The quantification of market risk using VAR provides a
consistent measure of risk across diverse energy markets and products. VAR
represents an estimate of reasonably possible net losses in earnings that would
be recognized on its portfolio assuming hypothetical movements in future market
rates and is not necessarily indicative of actual results that may occur.

Avista Energy's VAR computations utilize several key assumptions, including a
95% confidence level for the resultant price movement and a one-day holding
period. The calculation includes derivative commodity instruments held for
trading purposes and excludes the effects of written and embedded physical
options in the trading portfolio.

At December 31, 1998, Avista Energy's estimated potential one-day unfavorable
impact on gross margin was $3.3 million, as measured by VAR, related to its
commodity trading and marketing business. The average daily VAR for 1998 was
$3.0 million. Changes in markets inconsistent with historical trends or
assumptions used could cause actual results to exceed predicted limits. Market
risks associated with derivative commodity instruments held for purposes other
than trading were not material at December 31, 1998.

In addition to commodity price risk, the Company's commodity positions are also
subject to operational and event risks including, among others, increases in
load demand, transmission or transport disruptions, fuel quality specifications
and forced outages at generating plants.

Foreign Currency Risk The Company has investments in several Canadian companies
through Pentzer's acquisition of Universal Showcase, Inc. and Avista Energy
Canada, Ltd. and its acquisition of Coast Pacific Management, Inc. (see Note 21
for additional information about these acquisitions). The Company's exposure to
foreign currency risk and other foreign operations risk was immaterial to the
Company's consolidated results of operations and financial position in 1998 and
is not expected to change materially in the near future.

OTHER

On July 28, 1998, the United States District Court for the District of Idaho
issued its finding that the Coeur d' Alene Tribe of Idaho (Tribe) owns the bed
and banks of the Coeur d' Alene Lake and the St. Joe River lying within the
current boundaries of the Coeur d' Alene Reservation. The disputed bed and banks
comprise approximately the southern one-third of the Coeur d' Alene Lake. This
action had been brought by the United States on behalf of the Tribe against the
State of Idaho. The decision has been appealed by the State of Idaho to the
Ninth Circuit. While the Company is not a party to this action, it is meeting
with the Tribe to evaluate the impact of this decision on storage rights on the
reservoir and operation of the Company's hydroelectric facilities on the Spokane
River, downstream of the Coeur d' Alene Lake, which is the reservoir for these
plants.

The Board of Directors considers the level of dividends on the Company's common
stock on a continuing basis, taking into account numerous factors including,
without limitation, the Company's results of operations and financial condition,
as well as general economic and competitive conditions. The Company's net income
available for dividends is derived from its retail electric and natural gas
utility operations.

SAFE HARBOR FOR FORWARD-LOOKING STATEMENTS

The Company is including the following cautionary statement in this Form 10-K to
make applicable and to take advantage of the safe harbor provisions of the
Private Securities Litigation Reform Act of 1995 for any forward-looking
statements made by, or on behalf of, the Company. Forward-looking statements
include statements concerning plans, objectives, goals, strategies, future
events or performance, and underlying assumptions (many of which are based, in
turn, upon further assumptions) and are all statements which are other than
statements of historical fact, including without limitation those that are
identified by the use of the words "anticipates," "estimates," "expects,"
"intends," "plans," "predicts," and similar expressions. From time to time, the
Company may publish or otherwise make available forward-looking statements of
this nature. All such subsequent forward-looking statements, whether written or
oral and whether made by or on behalf of the Company, are also expressly
qualified by these cautionary statements.

Forward-looking statements involve risks and uncertainties which could cause
actual results or outcomes to differ materially from those expressed. The
Company's expectations, beliefs and projections are expressed in good faith and
are believed by the Company to have a reasonable basis, including without
limitation management's examination of historical operating trends, data
contained in the Company's records and other data available from third parties,
but there can be no assurance that the Company's expectations, beliefs or
projections will be achieved or accomplished. Furthermore, any forward-looking
statement speaks only as of the date on which such statement is made, and the
Company undertakes no obligation to update any forward-looking statement or
statements to reflect events or circumstances that occur after the date on which
such statement is made or to reflect the occurrence of unanticipated events. New
factors emerge from time to time, and it is not possible for management to
predict all of such factors, nor can it assess the impact of each such factor on
the Company's business or the extent to which any such factor, or combination of
factors, may cause actual results to differ materially from those contained in
any forward-looking statement.

Energy Delivery and Generation and Resources Operations -

In addition to other factors and matters discussed elsewhere herein, some
important factors that could cause actual results or outcomes for the Company

evolving from federal and/or state legislation, regulatory actions by state
utility commissions, demand for and availability of energy throughout the
country, wholesale competition, availability of economic supplies of natural
gas, margins on purchased power, and the formation of additional alliances or
entities.

Non-Energy Operations -

Certain important factors which could cause actual results or outcomes for the
Company's non-energy operations to differ materially from those discussed in
forward-looking statements include competition from other companies, the ability
to obtain new customers and retain old ones, reliability of customer orders,
business acquisitions, disposal of assets, the ability to obtain funds from
operations, debt or equity, research and development findings and the
availability of economic expansion or development opportunities.

Factors Common to All Operations -

The business and profitability of the Company are also influenced by economic
risks, changes in and compliance with environmental and safety laws and
policies, weather conditions, population growth rates and demographic patterns,
market demand for energy from plants or facilities, changes in tax rates or
policies, unanticipated project delays or changes in project costs,
unanticipated changes in operating expenses or capital expenditures, labor
negotiation or disputes, changes in credit ratings or capital market conditions,
inflation rates, inability of the various counterparties to meet their
obligations with respect to the Company's financial instruments, changes in
accounting principles and/or the application of such principles to the Company,
changes in technology and legal proceedings.

AVISTA CORPORATION
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

Avista Corporation (Avista Corp. or the Company), formerly The Washington Water
Power Company, was incorporated in the State of Washington in 1889, and operates
as a regional utility providing electric and natural gas sales and services and
as a national entity providing both energy and non-energy products and services.
The utility portion of the Company, doing business as Avista Utilities, consists
of two lines of business which are subject to state and federal price regulation
- -- (1) Energy Delivery and (2) Generation and Resources. The national businesses
are conducted under Avista Capital, which is the parent company to the Company's
subsidiaries.

Changes underway in the utility and energy industries are creating new
opportunities to expand the Company's businesses and serve new markets. In
pursuing such opportunities, the Company is shifting its strategic direction to
growth in order to achieve its goal of becoming a diversified North American
energy company.

The Company's growth strategy will expose the Company to risks associated with
rapid expansion, challenges in recruiting and retaining qualified personnel,
risks associated with acquisitions and joint ventures and increasing
competition. In addition, growth in the energy trading and marketing business
will expose the Company to increased financial and credit risks associated with
commodity trading activities. The Company believes that its extensive
experience in the electric and natural gas business, coupled with its strong
management team, will allow the Company to effectively manage its transition
to a diversified North American energy company.

The Energy Delivery line of business includes transmission and distribution
services for retail electric operations, all utility natural gas operations, and
other energy products and services. Usage by retail customers varies from year
to year primarily as a result of weather conditions, customer growth, the
economy in the Company's service area, conservation efforts, appliance
efficiency and other technology.

The Generation and Resources line of business includes the generation and
production of electric energy, and short- and long-term electric and natural gas
sales trading and wholesale marketing primarily to other utilities and power
brokers in the western United States. Energy trading includes short-term sales
and purchases, such as next hour, next day and monthly blocks of energy.
Wholesale marketing includes sales and purchases under long-term contracts with
one-year and longer terms. Generation and Resources manages the Company's
electric energy resource portfolio, which is used to serve Energy Delivery's
retail electric customers and Generation and Resources' wholesale electric
customers. In managing the electric energy resource portfolio, Generation and
Resources seeks to optimize the availability and operations of generation
resources. Revenues and the cost of electric power purchases vary from year to
year depending on the electric wholesale power market, which is affected by
several factors, including the availability of water for hydroelectric
generation, the availability of base load plants in the region, marginal fuel
prices and the demand for power in other areas of the country. Other factors
affecting the wholesale power market include lower unit margins on new sales
contracts than were realized in the past, fewer long-term power contracts being
entered into, deregulation of the electric utility industry and competition from
low cost generation being developed by independent power producers.

Avista Capital is the parent company to the National Energy Trading and
Marketing and Non-energy businesses. The National Energy Trading and Marketing
businesses are conducted by Avista Energy, Avista Advantage and Avista Power.
Avista Energy focuses on commodity trading, energy marketing and other related
businesses on a national basis. Avista Energy's business is affected by several
factors, including the demand for and availability of power throughout the
United States, lower unit margins on new sales contracts, fewer long-term power
contracts being entered into, marginal fuel prices and deregulation of the
electric utility industry. Avista Advantage provides a variety of energy-related
products and services to commercial and industrial customers on a national
basis. Its primary product lines include consolidated billing, resource
accounting, energy analysis and load profiling. Avista Power was formed in
December 1998 to develop and own generation assets primarily in support of
Avista Energy. Avista Power operations had no impact on 1998 earnings.

The Non-energy business is conducted primarily by Pentzer Corporation (Pentzer),
which is the parent company to the majority of the Company's Non-energy
businesses. Pentzer's business strategy is such that its earnings result from
both transactional and non-transactional earnings. Transactional gains arise
from a one-time event or a specific transaction, such as the sale of an
investment or individual company from Pentzer's portfolio of investments.
Non-transactional earnings arise out of the ongoing operations of the individual
portfolio companies.

BASIS OF REPORTING

The financial statements are presented on a consolidated basis and, as such,
include the assets, liabilities, revenues and expenses of the Company and its
wholly owned subsidiaries. All material intercompany transactions have been
eliminated in the consolidation. The accompanying financial statements include
the Company's proportionate share of utility plant and related operations
resulting from its interests in jointly owned plants (See Note 6). The financial
activity of each of the Company's lines of business is reported in the "Schedule
of Information by Business



49
54
AVISTA CORPORATION
- --------------------------------------------------------------------------------

Segments." Such information is an integral part of these financial statements.

The preparation of the Company's consolidated financial statements in conformity
with generally accepted accounting principles necessarily requires management to
make estimates and assumptions that directly affect the reported amounts of
assets, liabilities, revenues and expenses.

ALLOCATION OF REVENUES AND EXPENSES FOR REPORTING BUSINESS SEGMENTS

A portion of the utility's revenues and expenses have been allocated between the
two business segments in order to report results of operations by the individual
lines of business - (1) Energy Delivery and (2) Generation and Resources. The
Energy Delivery business reports the results of the Company's transmission and
distribution services for retail electric operations and all natural gas
operations. Costs associated with electric energy commodities, such as purchased
power expense, as well as the revenues attributable to the recovery of such
costs from retail customers, have been eliminated from the Energy Delivery line
of business and are reflected in the results of the Generation and Resources
line of business. The transfer of revenues between the two utility lines of
business occurs through the use of a transfer price, primarily based on cost of
production studies, that is associated with the sale of a kilowatthour of
electricity. The results of all natural gas operations are included in the
Energy Delivery line of business because natural gas trackers allow natural gas
costs to pass through within that line of business without the commodity prices
having a material income effect. The Generation and Resources line of business
includes the generation and production of electric energy, and short- and
long-term electric and natural gas commodity trading and wholesale marketing
primarily to other utilities and power brokers in the western United States.

SYSTEM OF ACCOUNTS

The accounting records of the Company's utility operations are maintained in
accordance with the uniform system of accounts prescribed by the Federal Energy
Regulatory Commission (FERC) and adopted by the appropriate state regulatory
commissions.

REGULATION

The Company is subject to state regulation in Washington, Idaho and Montana for
its electric operations. Natural gas operations are regulated in Washington,
Idaho, Oregon and California. The Company is subject to regulation by the FERC
with respect to its wholesale electric transmission rates and the natural gas
rates charged for the release of capacity from the Jackson Prairie Storage
Project.

OPERATING REVENUES

The Company accrues estimated unbilled revenues for electric and natural gas
sales and services provided through month-end. Avista Energy follows the
mark-to-market method of accounting for energy contracts entered into for
trading and price risk management purposes. Avista Energy recognized revenue
based on the change in the market value of outstanding derivative commodity
sales contracts, net of future servicing costs and reserves, in addition to
revenue related to physical and financial contracts that have matured.

OTHER INCOME (DEDUCTIONS)--NET

Other income (deductions)-net is composed of the following items:

</TABLE>


EARNINGS PER SHARE

Financial Accounting Standard (FAS) No. 128, "Earnings Per Share," became
effective in the fourth quarter of 1997 and requires two presentations of
earnings per share - "basic" and "diluted." Basic earnings per share (EPS) is
computed by dividing income available to common shareholders by the weighted
average number of common shares outstanding for the period. Diluted EPS reflects
the potential dilution that could occur if dilutive securities, such as stock
options and convertible stock, were exercised or converted into common stock
that then shared in the earnings of the Company. See Note 18 for more
information regarding the EPS calculations.

UTILITY PLANT

The cost of additions to utility plant, including an allowance for funds used
during construction and replacements of units of property and betterments, is
capitalized. Costs of depreciable units of property retired plus costs of
removal less salvage are charged to accumulated depreciation.



50
55
AVISTA CORPORATION
- --------------------------------------------------------------------------------

ALLOWANCE FOR FUNDS USED DURING CONSTRUCTION

The Allowance for Funds Used During Construction (AFUDC) represents the cost of
both the debt and equity funds used to finance utility plant additions during
the construction period. In accordance with the uniform system of accounts
prescribed by regulatory authorities, AFUDC is capitalized as a part of the cost
of utility plant and is credited currently as a noncash item to Other Income
(see Other Income above). The Company generally is permitted, under established
regulatory rate practices, to recover the capitalized AFUDC, and a fair return
thereon, through its inclusion in rate base and the provision for depreciation
after the related utility plant has been placed in service. Cash inflow related
to AFUDC does not occur until the related utility plant investment is placed in
service.

The effective AFUDC rate was 10.67% in 1998, 1997 and 1996. The Company's AFUDC
rates do not exceed the maximum allowable rates as determined in accordance with
the requirements of regulatory authorities.

DEPRECIATION

For utility operations, depreciation provisions are estimated by a method of
depreciation accounting utilizing unit rates for hydroelectric plants and
composite rates for other properties. Such rates are designed to provide for
retirements of properties at the expiration of their service lives. The rates
for hydroelectric plants include annuity and interest components, in which the
interest component is 6%. For utility operations, the ratio of depreciation
provisions to average depreciable property was 2.60% in 1998, 2.59% in 1997 and
2.58% in 1996.

The average service lives and remaining average service lives, respectively, for
the following broad categories of property are: electric thermal production - 35
and 18 years; hydroelectric production - 100 and 80 years; electric transmission
- - 60 and 29 years; electric distribution - 40 and 32 years; and natural gas
distribution property - 44 and 31 years.

CASH AND CASH EQUIVALENTS

For the purposes of the Consolidated Statements of Cash Flows, the Company
considers all temporary investments with an initial maturity of three months or
less to be cash equivalents.

TEMPORARY INVESTMENTS

Investments in debt and marketable equity securities are classified as
"available for sale" and are recorded at fair value. Investments totaling $4.3
million and $5.8 million are included on the Consolidated Balance Sheets at
December 31, 1998 as other property and investments and current assets,
respectively. Investments totaling $28.2 million and $22.6 million are included
on the Consolidated Balance Sheets at December 31, 1997 as other property and
investments and current assets, respectively. Unrealized investment gains, as of
December 31, 1998 and 1997, of $0.02 million and $2.1 million, respectively, net
of taxes, are reflected as a component of other comprehensive income.

DEFERRED CHARGES AND CREDITS

The Company prepares its financial statements in accordance with the provisions
of FAS No. 71, "Accounting for the Effects of Certain Types of Regulation." A
regulated enterprise can prepare its financial statements in accordance with FAS
No. 71 only if (i) the enterprise's rates for regulated services are established
by or subject to approval by an independent third-party regulator, (ii) the
regulated rates are designed to recover the enterprise's cost of providing the
regulated services and (iii) in view of demand for the regulated services and
the level of competition, it is reasonable to assume that rates set at levels
that will recover the enterprise's costs can be charged to and collected from
customers. FAS No. 71 requires a cost-based, rate-regulated enterprise to
reflect the impact of regulatory decisions in its financial statements. In
certain circumstances, FAS No. 71 requires that certain costs and/or obligations
(such as incurred costs not currently recovered through rates, but expected to
be so recovered in the future) be reflected in a deferral account in the balance
sheet and not be reflected in the statement of income or loss until matching
revenues are recognized. If at some point in the future the Company determines
that it no longer meets the criteria for continued application of FAS No. 71 to
all or a portion of the Company's regulated operations, the Company could be
required to write off its regulatory assets and could be precluded from the
future deferral in the Consolidated Balance Sheet of costs not recovered through
rates at the time such costs were incurred, even if such costs were expected to
be recovered in the future.

The Company's primary regulatory assets include Investment in Exchange Power,
conservation programs, deferred income taxes, the provision for postretirement
benefits and debt issuance and redemption costs. Those items without a specific
line on the Consolidated Balance Sheets are included in Deferred Charges -
Other-net. Deferred credits include natural gas deferrals, unrecovered purchased
gas costs and the gain on the general office building sale/leaseback which is
being amortized over the life of the lease, and are included on the Consolidated
Balance Sheets as Non-current Liabilities and Deferred Credits - Other Deferred
Credits.

DEFERRED REVENUES

In December 1998, the Company received cash proceeds of $143.4 million from the
monetization of a contract in which the Company assigned and transferred certain
rights under a long-term power sales contract to a funding trust. The proceeds
were recorded as deferred revenue and are being amortized into revenues over the
16-year period of the long-term sales contract.

- --------------------------------------------------------------------------------

POWER AND NATURAL GAS COST ADJUSTMENT PROVISIONS

The Company has a power cost adjustment mechanism (PCA) in Idaho which allows
the Company to modify electric rates to recover or rebate a portion of the
difference between actual and allowed net power supply costs. The PCA tracks
changes in hydroelectric generation, secondary prices, related changes in
thermal generation and Public Utility Regulatory Policies Act of 1978 (PURPA)
contracts. Rate changes are triggered when the deferred balance reaches $2.2
million. A $3.1 million (2.7%) rebate was effective February 1, 1999, which will
expire January 31, 2000. The following surcharges and rebates were in effect
during the past three years: a $2.7 million (2.4%) rebate effective June 1,
1998, which will expire May 31, 1999; a $2.6 million (2.3%) rebate effective
September 1, 1997, which expired August 31, 1998; a $2.6 million (2.4%) rebate
effective June 1, 1997, which expired May 31, 1998; a $2.5 million (2.3%) rebate
effective September 1, 1996, which expired August 31, 1997; and a $2.3 million
(2.4%) surcharge effective September 1, 1995, which expired August 31, 1996. The
rebates balance and the deferred balance are included in the Current Liabilities
- - Other and Non-Current Liabilities and Deferred Credits - Other Deferred
Credits lines, respectively, on the Consolidated Balance Sheets.

Under established regulatory practices, the Company is also allowed to adjust
its natural gas rates from time to time to reflect increases or decreases in the
cost of natural gas purchased. Differences between actual natural gas costs and
the natural gas costs allowed in rates are deferred and charged or credited to
expense when regulators approve inclusion of the cost changes in rates. In
Oregon, regulatory provisions include a sharing of benefits and risks associated
with changes in natural gas prices, as well as a sharing of benefits if certain
threshold earnings levels are exceeded. The balance is included on the
Consolidated Balance Sheets as Non-current Liabilities and Deferred Credits -
Other Deferred Credits.

INCOME TAXES

The Company and its eligible subsidiaries file consolidated federal income tax
returns. Subsidiaries are charged or credited with the tax effects of their
operations on a stand-alone basis. The Company's federal income tax returns have
been examined with all issues resolved, and all payments made, through the 1994
return.

STOCK-BASED COMPENSATION

Compensation cost for stock options is measured as the excess of the quoted
market price of the Company's stock at the date of grant over the amount an
employee must pay to acquire the stock. Restricted stock is recorded as
compensation cost over the requisite vesting periods based on the market value
on the date of grant. The Company accounts for its stock-based compensation
using the intrinsic value method prescribed in Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees" rather than using the
fair-value-based method of accounting for stock-based employee compensation
plans as prescribed under FAS No. 123, "Accounting for Stock-Based
Compensation." However, the Company has adopted the disclosure requirements of
FAS No. 123. See Note 20 for more information about the Company's stock-based
compensation plans.

OTHER COMPREHENSIVE INCOME

Effective January 1, 1998, the Company adopted FAS No. 130, "Reporting
Comprehensive Income," which establishes new rules for the reporting and display
of comprehensive income (net income plus all other changes in net assets from
nonowner sources) and its components. The adoption had no impact on the
Company's net income or stockholders' equity. Prior year financial statements
have been reclassified to conform to these requirements. The following table
reflects the accumulated balances of other comprehensive income:

CUMULATIVE FOREIGN CURRENCY TRANSLATION ADJUSTMENT

Assets and liabilities of one of Pentzer's portfolio companies are denominated
in Canadian dollars and translated to U. S. dollars at exchange rates in effect
on the balance sheet date. Revenues, costs and expenses for the company are
translated using an average rate. Cumulative translation adjustments resulting
from this process are reflected as a component of other comprehensive income in
the shareholders' equity section in the Consolidated Statements of
Capitalization.

NEW ACCOUNTING STANDARDS

The Financial Accounting Standards Board (FASB) issued FAS No. 132, entitled
"Employers' Disclosures about Pensions and Other Postretirement Benefits," which
is effective for fiscal years beginning after December 15, 1997. This statement
revises disclosures, but does not change the measurement or recognition of the
plans. The Company adopted FAS No. 132 in 1998 and the required disclosure can
be found in Note 7.

The FASB issued FAS No. 133, entitled "Accounting for Derivative Instruments and
Hedging Activities" which will be effective for fiscal years beginning after
June 15, 1999. The statement requires that all derivative financial instruments
be recognized as either assets or liabilities on the company's balance sheets at
fair value. The accounting for changes in the fair value of a derivative will
depend on the intended use of the derivative and the resulting designation.
Avista Energy currently accounts for derivative commodity instruments entered
into for trading purposes using the mark-to-market method of accounting, in
compliance with EITF 98-10, "Accounting for Energy Trading and Risk Management
Activities." The Company is in the process of researching the statement and its
possible impact on the Company's financial position and results of operations.

RECLASSIFICATIONS

Certain prior year amounts have been reclassified to conform to current
statement format. These reclassifications were made for comparative purposes and
have not affected previously reported total net income or common shareholders'
equity.

NOTE 2. ACCOUNTS RECEIVABLE SALE

In July 1997, WWP Receivables Corp. (WWPRC) was incorporated as a wholly owned,
bankruptcy-remote subsidiary of the Company for the purpose of acquiring or
purchasing interests in certain accounts receivable, both billed and unbilled,
of the Company. Subsequently, WWPRC and the Company have entered into an
agreement whereby WWPRC can sell without recourse, on a revolving basis, up to
$80.0 million in those receivables. WWPRC is obligated to pay fees which
approximate the purchaser's cost of issuing commercial paper equal in value to
the interests in receivables sold. On a consolidated basis, the amount of such
fees is included in operating expenses of the Company. At December 31, 1998 and
1997, $25.0 million and $40.0 million, respectively, in receivables had been
sold pursuant to the agreement, which qualify as sales of assets under FAS No.
125.

NOTE 3. ENERGY COMMODITY TRADING

The Company's energy-related businesses are exposed to risks relating to changes
in certain commodity prices and counterparty performance. In order to manage the
various risks relating to these exposures, the Company utilizes electric,
natural gas and related derivative commodity instruments, such as forwards,
futures, swaps and options, and Avista Energy engages in the trading of such
instruments. The Company and Avista Energy have adopted policies and procedures
to manage the risks inherent these activities and have established a
comprehensive Risk Management Committee, separate from the units that create
such risk exposure and overseen by the Audit and Finance Committee of the
Company's Board of Directors, to monitor compliance with the Company's risk
management policies and procedures.

GENERATION AND RESOURCES

The Company protects itself against price fluctuations on electric energy and
natural gas by limiting the aggregate level of net open positions which are
exposed to market price changes and through the use of electric, natural gas and
related derivative commodity instruments for hedging purposes. The net open
position is actively managed with strict policies designed to limit the exposure
to market risk and which require daily and weekly reporting to management of
potential financial exposure. The Risk Management Committee has limited the
types of commodity instruments the Company may trade to those related to
electricity and natural gas commodities and those instruments are to be used for
hedging price fluctuations associated with the management of resources.
Commodity instruments are not generally held by the Company for speculative
trading purposes. Gains and losses related to derivative commodity instruments
which qualify as hedges are recognized in the Consolidated Statements of Income
when the underlying hedged physical transaction closes (the deferral method) and
are included in the same category as the hedged item (natural gas purchased or
purchased power expense, as the case may be). At December 31, 1998 and 1997, the
Company's derivative commodity instruments outstanding were immaterial.

NATIONAL ENERGY TRADING AND MARKETING

Avista Energy purchases natural gas and electricity directly from producers and
other trading companies, and its customers include commercial and industrial
end-users, electric utilities, natural gas distribution companies, and other
trading companies. Avista Energy's marketing and energy risk management services
are provided through the use of a variety of derivative commodity contracts to
purchase or supply natural gas and electric energy at specified delivery points
and at specified future dates. Avista Energy also trades natural gas and
electricity derivative financial instruments on national exchanges and through
other unregulated exchanges and brokers from whom these commodity derivatives
are available, and therefore experiences net open positions in terms of price,
volume, and specified delivery point.

The open position exposes Avista Energy to the risk that fluctuating market
prices may adversely impact its financial position or results of operations.
However, the net open position is actively managed with strict policies designed
to limit the exposure to market risk and which require daily reporting to
management of potential financial exposure. These policies include statistical
risk tolerance limits using historical price movements to calculate daily
earnings at risk as well as total Value-at-Risk (VAR) measurement.

Derivative commodity instruments sold and purchased by Avista Energy include:
forward contracts, involving physical delivery of an energy commodity; futures
contracts, which involve the buying or selling of natural gas, electricity or
other energy-related commodities at a fixed price; over-the-counter swap
agreements which require Avista Energy to receive or make payments based on the
difference between a specified price and the actual price of the underlying
commodity; and options, which mitigate price risk by providing for the right,
but not the requirement, to buy or sell energy-related commodities at a fixed
price.

Foreign currency risks associated with the fair value of the energy commodity
portfolio are managed using a variety of financial instruments, including
forward rate agreements.

Avista Energy's trading activities are subject to mark-to-market accounting,
under which changes in the market value of outstanding electric, natural gas and
related derivative commodity instruments are recognized as gains or losses in
the period of change. Gains and losses on electric, natural gas and related
derivative commodity instruments utilized for trading are recognized in income
on a current basis (the mark-to-market method) and are included on the
Consolidated Statements of Income in operating revenues or resource costs, as
appropriate, and on the Consolidated Balance Sheets as current or non-current
energy commodity assets or liabilities. Contracts in a receivable position, as
well as the options held, are reported as assets. Similarly, contracts in a
payable position, as well as options written, are reported as liabilities.
Cashflows are recognized during the period of settlement.

Contract Amounts and Terms Under Avista Energy's derivative instruments, Avista
Energy either (i) as "fixed price payor," is obligated to pay a fixed price or
amount and is entitled to receive the commodity (or currency) or a variable
amount or (ii) as "fixed price receiver," is entitled to receive a fixed price
or amount and is obligated to deliver the commodity (or currency) or pay a
variable amount. The contract or notional amounts and terms of Avista Energy's
derivative commodity investments outstanding at December 31, 1998 are set forth
below (volumes in thousands of mmBTUs and MWhs, dollars in thousands):

</TABLE>

At December 31, 1998, Avista Energy also had sales and purchase commitments
associated with contracts based on market prices totaling 898,316,063 mmBTUs,
with terms extending up to 12 years. Fixed index electric transactions totaled
1,875,576 MWhs, with terms extending up to 10 years.

Contract or notional amounts reflect the volume of transactions, but do not
necessarily represent the amounts exchanged by the parties to the derivative
instruments. Accordingly, contract or notional amounts do not accurately
measure Avista Energy's exposure to market or credit risks. The maximum terms
in years detailed above are not indicative of likely future cash flows as these
positions may be offset in the markets at any time in response to Avista
Energy's risk management needs.

The weighted average term of Avista Energy's natural gas and related derivative
commodity instruments as of December 31, 1998 was approximately three months.
The weighted average term of Avista Energy's electric derivative commodity
instruments at year-end was approximately ten months. The change in the fair
value position of Avista Energy's energy commodity portfolio, net of the
reserves for credit and market risk from December 31, 1997 to December 31, 1998
was $22.8 million and is included on the Consolidated Statements of Income in
operating revenues.

MARKET RISK

The Company manages, on a portfolio basis, the market risks inherent in its
activities subject to parameters established by its Risk Management Committee.
Market risks are monitored by the Risk Management Committee to ensure compliance
with the Company's stated risk management policies. The Company measures the
risk in its portfolio on a daily basis in accordance with value-at-risk and
other risk methodologies established by the Risk Management Committee. The
quantification of market risk using value-at-risk provides a consistent measure
of risk across diverse energy markets and products.

CREDIT RISK

The Company is exposed to credit risk in the event of nonperformance by
customers or counterparties of their contractual obligations. The concentration
of customers and/or counterparties may impact overall exposure to credit risk,
either positively or negatively, in that the counterparties may be similarly
affected by changes in economic, regulatory or other conditions. However, the
Company maintains credit policies with regard to their customers and
counterparties that management believes significantly minimize overall credit
risk. These policies include an evaluation of potential customers' and
counterparties' financial condition and credit rating, collateral requirements
or other credit enhancements such as letters of credit or parent company
guarantees, and the use of standardized agreements which allow for the netting
or offsetting of positive and negative exposures associated with a single
counterparty. The Company maintains credit reserves which are based on
management's evaluation of the credit risk of the overall portfolio. Based on
these policies, exposures and the credit reserves, the Company does not
anticipate a materially adverse effect on financial position or results of
operations as a result of customer or counterparty nonperformance. New York
Mercantile Exchange traded futures and option contracts are financially
guaranteed by the Exchange and have nominal credit risk.

Avista Energy has concentrations of suppliers and customers in the electric and
natural gas industries, including electric utilities, natural gas distribution
companies and other energy marketing and trading companies. In addition, Avista
Energy has concentrations of credit risk related to geographic location. Avista
Energy operates in North America, principally within the West and Mid-West
United States and Western Canada. These concentration of counterparties and
concentrations of geographic location may impact Avista Energy's overall
exposure to credit risk, either positively or negatively, in that the
counterparties may be similarly affected by changes in economic, regulatory or
other conditions.

NOTE 4. NATIONAL ENERGY TRADING AND MARKETING EQUITY INVESTMENT

Effective November 30, 1998, Avista Energy sold its 50% ownership interest in
Howard/Avista Energy LLC to H&H Star Energy, Inc. The sales price, which
represented Avista Energy's equity investment, was $25 million in the form of a
short-term unsecured note receivable from H&H Star Energy, Inc., and is
guaranteed by H&H Star Energy, Inc.'s parent company, Howard Publications, Inc.
The note is due April 30, 1999.

The Company's initial equity investment in Howard/Avista Energy, LLC was $25
million and the investment in the net assets of the unconsolidated subsidiary
amounted to $26.8 million at December 31, 1997. Dividends of $0.7 million were
received from Howard/Avista Energy, LLC in 1998. Avista Energy's pre-tax equity
in earnings of Howard/Avista Energy LLC were $(1.0) million and $1.8 million for

NOTE 7. PENSION PLANS AND OTHER POSTRETIREMENT BENEFIT PLANS

The Company has a pension plan covering substantially all of its regular
full-time employees. Certain of the Company's subsidiaries also participate in
this plan. Individual benefits under this plan are based upon years of service
and the employee's average compensation as specified in the Plan. The Company's
funding policy is to contribute annually an amount equal to the net periodic
pension cost, provided that such contributions are not less than the minimum
amounts required to be funded under the Employee Retirement Income Security Act,
nor more than the maximum amounts which are currently deductible for tax
purposes. Pension fund assets are invested primarily in marketable debt and
equity securities. The Company also has other plans which cover the executive
officers and key managers.

The Company provides certain health care and life insurance benefits for
substantially all of its retired employees. The Company accrues the estimated
cost of postretirement benefit payments during the years that employees provide
services and allows recognition of the unrecognized transition obligation in the
year of adoption or the amortization of such obligation over a period of up to
twenty years. The Company elected to amortize this obligation of approximately
$34,500,000 over a period of twenty years, beginning in 1993.

Assumed health cost trend rates have a significant effect on the amounts
reported for the health care plans. A one-percentage-point increase in the
assumed health care cost trend rate for each year would increase the accumulated
postretirement benefit obligation as of December 31, 1998 by approximately $2.6
million and the service and interest cost by approximately $212,000.

The Company also sponsors an employee savings plan which covers substantially
all employees. Employer matching contributinos of $2.8 million, $2.9 million
and $2.8 million were expensed in 1998, 1997 and 1996, respectively.

NOTE 8. ACCOUNTING FOR INCOME TAXES

In June 1997, the Company received $81 million from the Internal Revenue Service
(IRS) to settle an income tax claim relating to its investment in the terminated
nuclear project 3 of the Washington Public Power Supply System (WNP3). The $81
million recovery included $34 million in income taxes the Company overpaid in
prior years plus $47 million in accrued interest, which in total contributed
$41.4 million, or $0.74 per share, to net income.



57
62
AVISTA CORPORATION
- --------------------------------------------------------------------------------

The Company had claimed that it realized a loss in 1985 relating to its $195
million investment in WNP3 entitling it to current tax deductions. The IRS,
however, originally denied the Company's claim and ruled that the investment
should be written off over 32.5 years, the term of a settlement agreement
between the Company and the Bonneville Power Administration relating to WNP3.
The Company disagreed with this ruling and had been pursuing a reversal for
several years. The IRS has now agreed with the Company's position.

The Company entered into settlement agreements with the WUTC and the IPUC in
1987 and 1988 providing for the recovery through retail prices of approximately
60% of the Company's $195 million investment in WNP3. As a result of these
agreements, customers have been and will continue to receive the tax benefits
relating to the recoverable portion of WNP3 over the recovery periods specified
in the settlement agreements. The settlement agreements resulted in a write-off
of approximately $75 million of the Company's WNP3 investment, with the entire
write-off charged to shareholders. The tax recovery and related accrued interest
from the IRS will flow through to the benefit of shareholders. The cash was used
to fund new business investment, including growth opportunities in national
energy markets, and reduced the need for issuance of long-term debt during 1997.

As of December 31, 1998 and 1997, the Company had recorded net regulatory assets
of $171.0 million and $176.7 million, respectively, related to the probable
recovery of FAS No. 109, "Accounting for Income Taxes," deferred tax liabilities
from customers through future rates. Such regulatory assets will be adjusted by
amounts recovered through rates.

Deferred income taxes reflect the net tax effects of (a) temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes, and (b) tax credit
carryforwards. The net deferred federal income tax liability consists of the
following (thousands of dollars):

NOTE 9. LONG-TERM PURCHASED POWER CONTRACTS WITH REQUIRED MINIMUM PAYMENTS

Under fixed contracts with Public Utility Districts (PUD), the Company has
agreed to purchase portions of the output of certain generating facilities.
Although the Company has no investment in such facilities, these contracts
provide that the Company pay certain minimum amounts (which are based at least
in part on the debt service requirements of the supplier) whether or not the
facility is operating. The cost of power obtained under the contracts, including
payments made when a facility is not operating, is included in operations and
maintenance expense in the Consolidated Statements of Income. Information as of
December 31, 1998, pertaining to these contracts is summarized in the following

Avista Energy and its subsidiary, Avista Energy Canada, Ltd., as co-borrowers,
have a credit agreement with a commercial bank in the aggregate amount of $100
million, expiring April 1, 1999. The credit agreement may be terminated by the
bank at any time and all extensions of credit under the agreement are payable
upon demand, in either case at the bank's sole discretion. The agreement also
provides, on an uncommitted basis, for the issuance of letters of credit to
secure contractual obligations to counterparts. The facility is guaranteed by
Avista Capital and is secured by substantially all of Avista Energy's assets.
The maximum cash component of credit extended by the bank is $30 million, with
availability of up to $100 million for the issuance of letters of credit. At
December 31, 1998 and 1997, there were no cash advances (demand notes payable)
outstanding. Letters of credit outstanding under the facility totaled
approximately $20.2 million and $2.8 million at December 31, 1998 and 1997,
respectively. The total amount of unused credit available to the Company at
December 31, 1998 was $79.8 million.

Non-energy operations have $54.0 million in short-term borrowing arrangements
available. At December 31, 1998 and 1997, $21.4 million and $18.6 million,
respectively, were outstanding.

NOTE 12. LEASES

The Company has entered into several lease arrangements involving various
assets, with minimum terms ranging from one to thirteen years and expiration
dates from 1999 to 2011. Certain of the lease arrangements require the Company,
upon the occurrence of specified events, to purchase the leased assets for
varying amounts over the term of the lease. The Company's management believes
that the likelihood of the occurrence of the specified events under which the
Company could be required to purchase the property is remote. Rent expense for
the years ended December 31, 1998, 1997 and 1996 was $17.6 million, $16.9
million and $15.2 million, respectively. Future minimum lease payments (in
thousands of dollars) required under operating leases that have initial or
remaining noncancelable lease terms in excess of one year as of December 31,
1998 are estimated as follows:

The Company also has various other cancelable operating leases, which are
charged to operating expense, consisting of the Rathdrum combustion turbines,
the Company airplane and a large number of small, relatively short-term,
renewable agreements for various items, such as office equipment and office
space.

NOTE 14. CONVERTIBLE PREFERRED STOCK

In December 1998, as part of a dividend restructuring plan, the Company issued
1,540,460 shares of its $12.40 Convertible Preferred Stock, Series L, in
exchange for 15,404,595 shares of common stock, on the basis of a one-tenth
interest in one share of preferred stock for each share of common stock. The
Convertible Preferred Stock, Series L has a liquidation preference of $182.8125
per share.

Unless previously converted into common stock by the Company, on November 1,
2001 each share of the Convertible Preferred Stock, Series L will be converted
into (1) ten shares of common stock (subject to antidilution adjustments) and
(2) the right to receive an amount, in cash, equal to accrued and unpaid
dividends.

The Convertible Preferred Stock, Series L may be converted, at the option of the
Company, at any time prior to November 1, 2001, in whole but not in part, into,
for each share so converted (1) a number of shares of common stock equal to the
Optional Conversion Price then in effect, plus (2) the right to receive an
amount, in cash, equal to the accrued and unpaid dividends thereon to but
excluding the conversion date, plus (3) the right to receive the Optional
Conversion Premium. As used above,

* the "Optional Conversion Price" will be, for each share of Convertible
Preferred Stock, Series L so converted, a number of shares of common
stock equal to the lesser of (a) the amount of $24 divided by an amount
equal to the current market price of the common stock, multiplied by ten
and (b) one share of common stock (subject to antidilution adjustments);
and

* the "Optional Conversion Premium" will be, for each share of Convertible
Preferred Stock, Series L so converted, an amount in cash, initially
equal to $20.90, declining by $0.02111 for each day following December
15, 1998 to and including the optional conversion date and equal to zero
on and after September 15, 2001; provided, however, that in lieu of
delivering such amount in cash, the Company may, at its option, deliver
a number of shares of common stock equal to the quotient of such amount
divided by an amount equal to the current market price of the common
stock.

NOTE 15. COMPANY-OBLIGATED MANDATORILY REDEEMABLE PREFERRED TRUST SECURITIES

On January 23, 1997, Avista Capital I, a business trust, issued to the public
$60,000,000 of Preferred Trust Securities having a distribution rate of 7 7/8%.
Concurrent with the issuance of the Preferred Trust Securities, the Trust issued
$1,855,675 of Common Trust Securities to the Company. The sole assets of the
Trust are the

67
AVISTA CORPORATION
- --------------------------------------------------------------------------------

Company's 7 7/8% Junior Subordinated Deferrable Interest Debentures, Series A,
with a principal amount of $61,855,675. These debt securities may be redeemed
at the Company's option on or after January 15, 2002 and mature January 15,
2037.

On June 3, 1997, Avista Capital II, a business trust, issued to the public
$50,000,000 of Preferred Trust Securities having a floating distribution rate of
LIBOR plus 0.875%, calculated and reset quarterly (initially 6.6875%). The
distribution rate paid during 1998 ranged from 6.77734% to 6.13625%, which was
the rate outstanding at December 31, 1998. Concurrent with the issuance of the
Preferred Trust Securities, the Trust issued $1,547,000 of Common Trust
Securities to the Company. The sole assets of the Trust are the Company's
Floating Rate Junior Subordinated Deferrable Interest Debentures, Series B, with
a principal amount of $51,547,000. These debt securities may be redeemed at the
Company's option on or after June 1, 2007 and mature June 1, 2037.

The Company has guaranteed the payment of distributions on, and redemption price
and liquidation amount in respect of, the Preferred Trust Securities to the
extent that the Trust has funds available for such payment from the debt
securities. Upon maturity or prior redemption of such debt securities, the Trust
Securities will be mandatorily redeemed. The Company's Consolidated Statements
of Capitalization reflect only the $60 million and $50 million of Preferred
Trust Securities, accordingly all intercompany transactions have been
eliminated.

NOTE 16. FAIR VALUE OF FINANCIAL SECURITIES

The fair value of the Company's long-term debt (excluding notes payable and
other) at December 31, 1998 and 1997 is estimated to be $735.5 million, or 107%
of the carrying value and $647.3 million, or 105% of the carrying value,
respectively. The fair value of the Company's mandatorily redeemable preferred
stock at December 31, 1998 and 1997 is estimated to be $38.5 million, or 110% of
the carrying value and $49.8 million, or 111% of the carrying value,
respectively. The fair value of the Company's preferred trust securities at
December 31, 1998 and 1997 is estimated to be $106.9 million, or 97% of the
carrying value and $109.4 million, or 99% of the carrying value, respectively.
These estimates are all based on available market information. The fair value of
the Company's convertible preferred securities at December 31, 1998 was $301.4
million, or 112%, of the carrying value. This valuation was based on the closing
price of the securities on December 31, 1998.

NOTE 17. COMMON STOCK

In April 1990, the Company sold 1,000,000 shares of its common stock to the
Trustee of the Investment and Employee Stock Ownership Plan for Employees of the
Company (Plan) for the benefit of the participants and beneficiaries of the
Plan. In payment for the shares of Common Stock, the Trustee issued a promissory
note payable to the Company in the amount of $14,125,000. Dividends paid on the
stock held by the Trustee, plus Company contributions to the Plan, if any, are
used by the Trustee to make interest and principal payments on the promissory
note. The balance of the promissory note receivable from the Trustee ($9.3
million at December 31, 1998) is reflected as a reduction to common equity. The
shares of Common Stock are allocated to the accounts of participants in the Plan
as the note is repaid. During 1998, the cost recorded for the Plan was $3.7
million. Interest on the note payable to the Company, cash and stock
contributions to the Plan and dividends on the shares held by the Trustee were
$0.9 million, $2.8 million and $0.9 million, respectively.

In February 1990, the Company adopted a shareholder rights plan, which was
subsequently amended, pursuant to which holders of Common Stock outstanding on
March 2, 1990, or issued thereafter, have been granted one preferred share
purchase right (Right) on each outstanding share of Common Stock. Each Right,
initially evidenced by and traded with the shares of Common Stock, entitles the
registered holder to purchase one two-hundredth of a share of Preferred Stock of
the Company, without par value, at an exercise price of $40, subject to certain
adjustments, regulatory approval and other specified conditions. The Rights will
be exercisable only if a person or group acquires 10% or more of the Common
Stock or announces a tender offer, the consummation of which would result in the
beneficial ownership by a person or group of 10% or more of the Common Stock.
Upon any such acquisition, each Right would entitle the holder to purchase a
number of shares of Common Stock of the Company (or, in the case of a merger of
the Company into another person or group, common stock of the acquiring person)
having a fair market value equal to twice the exercise price. In no event will
the Rights be exercisable by a person which has acquired 10% or more of the
Company's Common Stock. The Rights may be redeemed, at a redemption price of
$0.005 per Right, by the Board of Directors of the Company at any time until any
person or group has acquired 10% or more of the Common Stock. The Rights will
expire on February 16, 2000.

During 1992, the Company received authorization to issue 1.5 million shares of
Common Stock under a second Periodic Offering Program (POP). No shares were
issued under the POP during 1996, 1997 or 1998. At December 31, 1998, 572,400
shares remained authorized but unissued.

The Company has a Dividend Reinvestment and Stock Purchase Plan under which the
Company's stockholders may automatically reinvest their dividends and make
optional cash payments for the purchase of the Company's Common Stock at current
market value.

The Company purchases stock on the open market to fulfill obligations of the
401(K) and Dividend Reinvestment Plans. Sales of Common Stock for 1998, 1997 and
1996 are summarized below (thousands of dollars):

NOTE 18. EARNINGS PER SHARE

Average shares outstanding for basic EPS were 54,603,926 in 1998. At December
31, 1998, 1,540,460 shares of $12.40 Convertible Preferred Stock, Series L,
which were convertible into 15,404,595 million shares of common stock, were
outstanding. All of these potential common shares were excluded from the
computation of diluted EPS for 1998 because their inclusion had an antidilutive
effect on EPS. Options to purchase 647,900 shares of common stock were
outstanding during 1998, but 150,000 shares were not included in the computation
of diluted earnings per share because the options' exercise price was greater
than the average market price of the common shares for the year and, therefore,
the effect would be antidilutive. Average number of common shares outstanding
for both basic and diluted EPS was 55,960,360 for both 1997 and 1996. Basic and
diluted EPS were the same in 1997 and 1996 as the Company did not have any
common stock equivalents outstanding in either of those years.

The computation of basic and diluted earnings per common share is as follows (in
thousands, except per share amounts):

NOTE 19. STOCK COMPENSATION PLANS

The Company and certain subsidiaries have adopted stock-based compensation
plans.

Avista Corp.

In 1998, the Company adopted and shareholders approved an incentive compensation
plan, the Long-Term Incentive Plan (Plan). Under the Plan, certain key
employees, directors and officers of the Company and its



64
69
AVISTA CORPORATION
- --------------------------------------------------------------------------------

subsidiaries may be granted stock options, stock appreciation rights, stock
awards (including restricted stock) and other stock-based awards and dividend
equivalent rights. The Company has made available a maximum of 2.5 million
shares of its common stock for grant under the Plan. The shares issued under the
Plan will be purchased by the trustee on the open market.

The following summarizes stock options activity for 1998 under the Plan:

<TABLE>

Exercisable Options - December 31, 1998 --

Option grants vest 25% per year over four
years and expire 10 years after issuance.

Weighted average exercise price of options
granted during the year $ 20.14

Weighted average fair value of options
granted during the year $ 4.74(1)
</TABLE>

(1) The fair values of these options were estimated at the dates of the
grants using a Black-Scholes option pricing model using the following
assumptions: dividend yield of 3.01%, expected volatility of 22.19%,
risk-free interest rate range of 4.81% to 5.53% depending on the grant
date, and an expected life of 7 years.

The Company granted 102,036 shares of restricted common stock under the Plan in
1998. Plan participants are entitled to dividends and to vote their respective
shares. The sale or transfer of restricted stock is prohibited during the
vesting period except as specified in the award agreements. The value of
restricted stock awards is established by the average market price on the date
of grant. Restricted stock awarded in 1998 have vesting periods from 4 - 5
years.

Common equity was reduced in the accompanying Consolidated Balance Sheets by the
cost of restricted shares acquired by the Plan trustee on the open market.
Accordingly, the Company is recording compensation expense ratably over the
restriction periods based on the reduction to common equity.

The Company accounts for stock based compensation using APB Opinion No. 25,
"Accounting for Stock Issued to Employees." Under this method, compensation cost
is recognized on the excess, if any, of the market price of the stock at grant
date over the exercise price of the option. As the exercise price for options
granted under the Plan was equal to the market price at grant date, no
compensation expense has been recorded by the Company in connection this the
Plan. In accordance with FAS No. 123, "Accounting for Stock-Based Compensation,"
compensation expense is determined based on the fair value of the award and
recognizes that cost over the service period. Had compensation costs for these
plans been determined based on the fair value at the grant dates with FAS No.
123, the Company's net income would have been reduced to the pro forma amounts
indicated below:

</TABLE>

(2) Includes pro forma effect of subsidiary companies stock option plans.

Subsidiary Companies

Certain subsidiaries of the Company have adopted employee stock incentive plans
under which key employees and directors were granted the opportunity to purchase
shares of subsidiary common stock at prices equal to the fair market value as
determined by each subsidiary's Board of Directors. Restricted shares are
subject to transfer agreements and vest over various periods as defined in the
plans. The subsidiaries record compensation expense based on the increase in the
adjusted net book value of the shares subject to the plans.

Certain subsidiaries of the Company have adopted employee stock incentive plans
under which certain employees and directors of the Company and the subsidiaries
are granted options to purchase subsidiary shares at prices no less than the
fair market value on the date of grant. Options outstanding under these plans
usually become fully

AVISTA CORPORATION
- --------------------------------------------------------------------------------

exercisable between three and five years from the date granted and terminate ten
years from the date granted. Upon termination of employment, vested options may
be exercised and the related subsidiary shares may be, but are not required to
be, repurchased by the applicable subsidiary at fair value.

NOTE 20. COMMITMENTS AND CONTINGENCIES

The Company believes, based on the information presently known, the ultimate
liability for the matters discussed in this note, individually or in the
aggregate, taking into account established accruals for estimated liabilities,
will not be material to the consolidated financial position of the Company, but
could be material to results of operations or cash flows for a particular
quarter or annual period. No assurance can be given, however, as to the ultimate
outcome with respect to any particular lawsuit.

NEZ PERCE TRIBE

On December 6, 1991, the Nez Perce Tribe filed an action against the Company in
U. S. District Court for the District of Idaho alleging, among other things,
that two dams formerly operated by the Company, the Lewiston Dam on the
Clearwater River and the Grangeville Dam on the South Fork of the Clearwater
River, provided inadequate passage to migrating anadromous fish in violation of
rights under treaties between the Tribe and the United States made in 1855 and
1863. The Lewiston and Grangeville Dams, which had been owned and operated by
other utilities under hydroelectric licenses from the Federal Power Commission
(the "FPC", predecessor of the FERC) prior to acquisition by the Company, were
acquired by the Company in 1937 with the approval of the FPC, but were
dismantled and removed in 1973 and 1963, respectively. Allegations of actual
loss under different assumptions ranged between $425 million and $650 million,
together with $100 million in punitive damages.

On November 21, 1994, the Company filed a Motion for Summary Judgment of
Dismissal. On March 28, 1996, a U.S. District judge entered a summary judgment
in favor of the Company dismissing the complaint. The Tribe filed a notice of
appeal to the Ninth Circuit Court of Appeals on April 24, 1996. A mediation
conference was held on October 11, 1996. Following the conclusion of that
conference, briefing schedules were vacated indefinitely to accommodate a
mediation process, which ultimately resulted in a settlement of this matter on
January 15, 1999. In accordance with that settlement, the Company will pay the
Nez Perce Tribe $2.5 million initially, part of which was already expensed and
the remainder deferred for possible future rate recovery. The Company will
provide 44 annual payments thereafter in the amount of $835,498 for utility
taxes, Tribal employment rights, fees and rights-of-ways, which will be expensed
as paid.

OIL SPILL

The Company completed an updated investigation of an oil spill from an
underground storage tank that occurred several years ago in downtown Spokane at
the site of the Company's steam heat plant. Underground soil testing conducted
in 1993 showed that the oil had migrated approximately one city block beyond the
steam plant property. The Clean-up Action Plan determined by the Department of
Ecology (DOE) is underway, and remediation facilities have been constructed and
installed and are being operated.

On August 17, 1995, a lawsuit was filed against the Company in Superior Court of
the State of Washington for Spokane County by Davenport Sun International Hotels
and Properties, Inc., the owner of a hotel property in downtown Spokane,
Washington. The Complaint alleged that the oil released from the Company's
Central Steamplant trespassed on property owned by the plaintiff. In addition,
the plaintiff claimed that the Steamplant has caused a diminution of value of
plaintiff's land. After mediation, the matter was resolved by settlement and
compromise, subject to certain conditions. In December 1997, the settlement was
restructured, certain amounts were paid, the litigation was dismissed with
prejudice, a release was obtained, and other conditions remain to be fulfilled,
none of which would affect the dismissal of this action.

The Company pursued recovery from insurers and reached settlement with one of
the two insurance carriers. On December 13, 1996, the Company filed a Complaint
for declaratory relief and money damages against Underwriters at Lloyds of
London (Lloyds), the remaining carrier, in Spokane County Superior Court. The
purpose of this action was to seek a declaration of the insurance policies
issued to the Company by Lloyds with respect to any liabilities of the Company
for environmental damage associated with the oil spill at the Central
Steamplant and other environmental remediation efforts. The policies at issue
were in effect during the period between 1926 and 1966; thereafter, the Company
maintained its policies with a new underwriter, Aegis. The Company's Complaint
sought money damages in excess of $16 million. On March 10, 1999, Avista Corp.
and Lloyds signed a settlement agreement resolving the claim.

SPOKANE GAS PLANT

The Company is participating with the Washington State Department of
Transportation in an environmental study relating to the former Spokane Natural
Gas Plant site (which was operated as a coal gasification plant for



66
71
AVISTA CORPORATION
- --------------------------------------------------------------------------------

approximately 60 years until 1948) acquired by the Company through a merger in
1958. The Company no longer owns the property. Initial core samples taken from
the site indicate environmental contamination at the site. On January 15, 1999,
the Company received notice from the State of Washington's Department of Ecology
that it had been designated as a potentially liable person (PLP) with respect to
any hazardous substances located on this site, stemming from the Company's past
ownership of the former Gas Plant. In its notice, the DOE stated that it
intended to complete an on-going remedial investigation of this site, complete a
feasibility study to determine the most effective means of halting or
controlling future releases of substances from the site, and implement
appropriate remedial measures.

The Company responded to the DOE acknowledging its listing as a PLP, but
requested that additional parties also be listed as PLPs. The Company also
committed to pursue additional characterization of the site, with more drillings
and samples, and is in the process of determining the extent of further work.
The Company will be negotiating with the DOE on the remedial measures.

EASTERN PACIFIC ENERGY

On October 9, 1998, Eastern Pacific Energy (Eastern Pacific), an energy
aggregator participating in the restructured retail energy market in California,
filed suit against the Company and its affiliates, Avista Advantage and Avista
Energy in the United States District Court for the Central District of
California. Eastern Pacific alleges, among other things, a breach of an oral or
implied joint venture agreement whereby the Company agreed to supply not less
than 300 megawatts of power to Eastern Pacific's California customers and that
Avista Advantage agreed to provide energy-related products and services. The
complaint seeks an unspecified amount of damages and also seeks to recover any
future profits earned from sales of the aforementioned amount of power to
California consumers. The Company and its affiliates intend to vigorously defend
against all of the claims.

On December 4, 1998, Avista Advantage, Avista Energy and the Company jointly
filed a motion to dismiss the complaint for failure to state a claim upon which
relief can be granted. Following a responsive pleading from the plaintiff, the
court took the matter under advisement and notified the parties that a decision
will be issued in due course concerning this motion to dismiss.

OTHER CONTINGENCIES

The Company routinely assesses, based on in-depth studies, expert analyses and
legal reviews, its contingencies, obligations and commitments for remediation of
contaminated sites, including assessments of ranges and probabilities of
recoveries from other responsible parties who have and have not agreed to a
settlement and recoveries from insurance carriers. The Company's policy is to
immediately accrue and charge to current expense identified exposures related to
environmental remediation sites based on estimates of investigation, cleanup and
monitoring costs to be incurred.

The Company must be in compliance with requirements under the Clean Air Act
Amendments (CAAA) by the year 2000 at both the Colstrip and Centralia thermal
generating plants, in which the Company maintains an ownership interest. The
anticipated share of costs at Colstrip are not expected to have a major economic
impact on the Company, but estimates at Centralia are expected to be
approximately $35 million, which have been included in the Company's future
projected capital expenditures.

The Company has potential liabilities under the Federal Endangered Species Act
(ESA) for species of fish that have either already been added to the endangered
species list, been listed as "threatened" or been petitioned for listing. Thus
far, measures which have been adopted and implemented have had minimal impact of
the Company. Future actions to save these, and other as yet unidentified fish or
wildlife species, particularly as the Company is relicensing several of its
hydroelectric facilities, could impact the Company's operations. It is currently
not possible to determine the likely financial impact of any further actions.

The Company has long-term contracts related to the purchase of fuel for thermal
generation, natural gas and hydroelectric power. Terms of the natural gas
purchase contracts range from one month to five years and the majority provide
for minimum purchases at the then effective market rate. The Company also has
various agreements for the purchase, sale or exchange of electric energy with
other utilities, cogenerators, small power producers and government agencies.

As of December 31, 1998, the Company's collective bargaining agreement with the
International Brotherhood of Electrical Workers represented approximately 50% of
employees. The current agreement with the union local representing the majority
of the bargaining unit employees expires on March 25, 2002. A local agreement in
the South Lake Tahoe area, which represents 7 employees, also expires on March
25, 1999. The Company and the union are currently negotiating this agreement.

NOTE 21. ACQUISITIONS AND DISPOSITIONS

In April 1998, Pentzer completed the purchase of two new companies that produce
store fixtures -- Universal Showcase, Ltd., in Toronto, Canada and Triangle
Systems, Inc., in New York. In October 1998, Pentzer acquired two additional
store fixtures companies -- Horizon Terra, Inc., in Indiana and Pacific Coast
Showcase, Inc., in Washington. During 1997, Pentzer acquired three new
companies: Target Woodworks, Inc., a Florida-based company; White Plus, a
California-based company; and Proco Wood Products, a Minnesota-based company.
All three companies provide point-of-purchase and in-store merchandising
services. During 1996, Pentzer acquired one company that provides
point-of-purchase and in-store merchandising services.

During the first quarter of 1998, Pentzer sold Systran Financial Services,
resulting in an after-tax gain of $5.5 million. In May 1997, Pentzer sold its
interest in a portfolio company, Safety Speed Cut, resulting in a gain of
approximately $2.0 million, net of taxes. In 1996, Pentzer Development
Corporation, a subsidiary of Pentzer, sold the Spokane Industrial Park,
resulting in a gain of approximately $10.8 million, net of taxes and other
adjustments.

In November 1998, the Company reached an agreement in principal to purchase a
majority ownership in One Eighty Communications, a competitive local exchange
carrier that provided local dial tone and data services to commercial accounts
in local communities. The acquisition was completed in January 1999, and the new
company was renamed Avista Communications. It will provide local high-speed
telecommunications services to under-served Northwest communities.

In December 1998, Avista Energy Canada, Ltd. acquired Coast Pacific Management,
Inc. (Coast Pacific), a natural gas marketing company based in Vancouver,
British Columbia, Canada. Coast Pacific manages and transports approximately
70,000 MMBtu of natural gas per day to some 70 large and medium size industrial
customers throughout British Columbia. Coast Pacific also acts as gas manager
for more than 40% of the large industrial market in the interior of British
Columbia.

Effective February 1, 1999, Avista Energy completed and closed the purchase of
Vitol Gas & Electric, LLC (Vitol), based in Boston, Massachusetts. Vitol is one
of the top 20 energy marketing companies in the United States. Vitol trades gas,
electricity, coal and SO2 allowances in markets in the eastern half of the
United States. The acquisition was funded through the issuance of additional
shares of common stock to Avista Capital.

NOTE 22. MERGER TERMINATION

On June 28, 1996, the Board of Directors of the Company terminated the Agreement
and Plan of Reorganization and Merger, dated as of June 27, 1994 by and among
the Company, Sierra Pacific Resources (SPR), Sierra Pacific Power Company, a
subsidiary of SPR (SPPC), and Altus Corporation, a wholly owned subsidiary of
the Company (Altus, formerly named Resources West Energy Corporation), which
would have provided for the merger of the Company, SPR and SPPC with and into
Altus. The Company had approximately $15.8 million, or $10.3 million after-tax,
in merger-related transaction and transition costs that were expensed in 1996.
No increase in rates occurred as a result of these costs being expensed.
