ITEM 1. BUSINESS.
 
ORGANIZATION AND HISTORY
 
    UtiliCorp United Inc. (the company, which may be referred to as we, us, or
our) is a multinational energy solutions provider. We conduct business through
the following business segments:
 
    - REGULATED BUSINESSES--includes our domestic utility generation,
      distribution and transmission businesses. Regulated businesses also
      includes appliance repair/servicing and limited gas marketing businesses.
 
    - AQUILA ENERGY--includes our natural gas and electricity marketing and
      trading businesses, and Aquila Gas Pipeline Corporation, a publicly traded
      natural gas gathering, processing and transportation company.
 
    - INTERNATIONAL--includes our investments in an electric distribution
      company in Australia, 79% owned UnitedNetworks Limited, (an electric
      transmission company) in New Zealand, a gas transportation and risk
      merchant company in the United Kingdom and an electric utility in Canada.
 
OUR STRATEGY
 
    Our strategy is to operate energy delivery networks and to be a leading
energy merchant in the markets in which we compete. We believe this strategic
focus positions us to compete effectively in a deregulated energy marketplace.
 
    The key elements of our strategy include:
 
    - ALIGNMENT OF BUSINESSES TO ADDRESS A CHANGING COMPETITIVE ENVIRONMENT. We
      believe that our distinct, yet inter-related, business groups enable us to
      better manage our operations in the changing marketplace in which we
      operate. Our corporate structure allows us to manage each of these
      businesses individually, improving our ability to maximize their
      profitability while providing low cost, high quality energy and energy
      related products and services to our customers.
 
    - PURSUIT OF STRATEGIC MERGERS, ACQUISITIONS, ALLIANCES, JOINT VENTURES AND
      PARTNERSHIPS. Growth through mergers and acquisitions has been a major
      part of our strategy for more than a decade. We believe that our
      approximately $2.7 billion of investments in mergers and acquisitions has
      played an integral role in establishing us as a leading diversified energy
      provider. Most recently, we have completed several transactions to enhance
      our operations in New Zealand and on March 11, 1999 submitted a winning
      bid for a gas utility in Australia.
 
    - IMPROVE OPERATIONAL EXCELLENCE. We constantly seek to improve our
      operational performance. Over the last several years we have consolidated
      operations of our domestic electric and natural gas distribution
      businesses. As an example, our Regulated Businesses group is implementing
      a single billing and accounting system for all of our domestic regulated
      utilities in eight states. We have reduced the number of field offices
      from 129 to 57, resulting in the elimination of 380 positions. We have
      developed an energy marketing, trading and risk management system at
      Aquila that will support substantially greater marketing and trading
      volumes without the need for material additional investment.
 
    - FOCUSED INTERNATIONAL OPERATIONS. Our International group is focused on
      seeking early entry into markets that provide a combination of stable and
      attractive political and economic environments and markets open or opening
      to competition in electric or natural gas sales. As an example, we were
      the first non-Australian company to invest in and manage an Australian
      electric distribution company. As owners and managers of our international
      operations, we seek to
 
                                       3
<PAGE>
      transfer our domestic knowledge and skills to improve the performance of
      those operations. At the same time, we benefit from experience gained in
      new, competitive international marketplaces, and we are using the
      knowledge gained overseas to better position ourselves for domestic
      deregulation.
 
    - RISK MANAGEMENT. In order to compete effectively and profitably in energy
      marketing and trading, we have an independent trading control officer who
      reports directly to our President and also reports independently to the
      Board of Directors. We closely monitor our operations and have written
      policies and established trading limits. We have developed proprietary
      risk management software which we license to other companies.
 
OUR COMPETITIVE STRENGTHS
 
    We believe that we have developed substantial competitive strengths that
will enable us to continue to successfully execute our strategy. These strengths
include:
 
    - Low cost, non-nuclear electric and natural gas utility businesses focused
      on superior customer service.
 
    - Market-leading position in energy marketing and trading.
 
    - Experienced management team whose compensation is directly tied to
      shareholder value.
 
    - Proven risk management policies and procedures to limit exposure to
      commodity market positions.
 
    - Successful operation of competitive non-regulated businesses
 
    - International operations in New Zealand, Australia, the United Kingdom,
      and Canada from which we believe we have gained valuable experience in
      competitive markets.
 
    - Proven track record of quickly and successfully integrating domestic and
      international mergers and acquisitions.
 
MERGERS & ACQUISITIONS
 
ST. JOSEPH LIGHT & POWER
 
    In March 1999, we signed a definitive agreement with St. Joseph Light &
Power Company to merge in a transaction valued at approximately $270 million.
The agreement is subject to approvals by St. Joseph shareholders, and by state
and federal regulatory agencies. The merger is expected to be completed sometime
in mid-2000.
 
MULTINET GAS/IKON ENERGY
 
    In March 1999, we and an Australian partner made a successful bid of $1.26
billion to acquire the natural gas utility Multinet Gas/Ikon Energy from the
State of Victoria, Australia. The acquisition is expected to be completed by
April 1999, with our ownership interest at 25.5%.

    Segment information for the three years ended December 31, 1998 is

    In April 1998, we were ordered to reduce Missouri electric rates by $16.9
million plus increase depreciation expense by $5.8 million. This rate reduction
lowered 1998 EBIT by $16.3 million.
 
ENVIRONMENTAL
 
    We are subject to various environmental laws. These include regulations
governing air and water quality and the storage and disposal of hazardous or
toxic wastes. We continually assess ways to ensure we comply with laws and
regulations on hazardous materials and hazardous waste and remediation
activities.
 
                                       6
<PAGE>
    We own or previously operated 29 former manufactured gas plants (MGP's)
which may, or may not, require some form of environmental remediation. We have
contacted appropriate federal and state agencies and are working to determine
what, if any, specific cleanup activities these sites may require.
 
    As of December 31, 1998, we estimate cleanup costs on our identified MGP
sites to be $10.0 million. This estimate could change materially when we have
investigated further. It could also be affected by the actions of environmental
agencies and the financial viability of other responsible parties. Ultimate
liability also may be affected significantly if we are held responsible for
parties unable to contribute financially to the cleanup effort.
 
    We have received favorable rate orders that enable us to recover
environmental cleanup costs in certain jurisdictions. In other jurisdictions,
there are favorable regulatory precedents for recovery of these costs. We are
also pursuing recovery from insurance carriers and other potentially responsible
parties.
 
    In December 1996, the U.S. Environmental Protection Agency (EPA) published
its final rule for nitrous oxide (NOx) emissions as required by the Clean Air
Act Amendments of 1990. The new NOx regulations require that we install
additional emissions control equipment at one of our power plants by January 1,
2000.
 
    In October 1998, the EPA published new air quality standards to further
reduce the emission of NOx. These more strict standards will require us to
install new equipment on our baseload coal units in Missouri that we estimate
will cost $35 million. The ultimate cost is under debate and subject to change.
The new standards as written are effective in May 2003.
 
    We do not expect final resolution of these environmental matters to have a
material adverse effect on our financial position or results of operations.
 
SEASONAL VARIATIONS OF BUSINESS
 
    Our utility and independent power project businesses are weather-sensitive.
We have both summer and winter peaking utility assets to reduce dependence on a
single peak season. The table below shows peak times for our utility businesses.

II.  AQUILA ENERGY
 
WHOLESALE ENERGY MARKETING
 
    Aquila's wholesale energy marketing business is conducted through various
operating units, collectively referred to as Energy Marketing. Energy Marketing
is a gas and power marketing company with a marketing, supply and transportation
network consisting of relations with gas producers, local distribution
companies, and end-users throughout the United States and Canada. Energy
Marketing adds value for customers by leveraging its national position in
financial deal structuring in gas and power marketing. It provides services such
as complex fuel supply arrangements, energy management services and project
development focused on control of mid-stream energy assets. For the five years
ended December 31, 1998, Energy Marketing had marketing volumes of 9.6, 6.8,
3.5, 1.9, and 1.4 billion cubic feet a day (BCF/d), respectively.
 
    In 1995, Energy Marketing began selling electricity to wholesale customers,
much as it markets natural gas. Aquila expects that the electricity marketing
industry will continue to expand rapidly as
 
                                       7
<PAGE>
liquidity and maturity increases. Aquila's wholesale power sales have grown from
129,000 megawatt hours (MWH) in 1995 to 121.2 million MWH in 1998, ranking it
third among the nation's largest volume power marketers.
 
    Energy Marketing utilizes certain types of fixed-price contracts in
connection with its natural gas and power marketing businesses. These include
contracts that commit us to purchase or sell natural gas and other commodities
at fixed prices in the future (i.e., fixed-price forward purchase and sales
contracts), futures and options contracts traded on the NYMEX and swaps and
other types of financial instruments traded in the over-the-counter financial
markets.
 
    The availability and use of these types of contracts allows us to manage and
hedge our contractual commitments, reduce our exposure relative to the
volatility of cash market prices, take advantage of carefully selected arbitrage
opportunities via open positions, protect our investment in natural gas storage
inventories and provide price risk management services to our customers. We are
also able to secure additional sources of energy or create additional markets
for existing supply through the use of exchange for physical transactions
allowed by NYMEX. We refer to our domestic and Canadian natural gas and
electricity trading activities as price risk management activities. These are
reflected in the accompanying financial statements using the mark-to-market
method of accounting.
 
    Although we generally attempt to balance our fixed-price physical and
financial purchase and sales contracts in terms of contract volumes and the
timing of performance and delivery obligations, net open positions often exist
or are established due to the origination of new transactions and our assessment
of, and response to, changing market conditions. We will occasionally create a
net open position or allow a net open position to continue when we believe,
based upon competitive information gained from our energy marketing activities,
that future price movements will be consistent with our net open position. When
we have a net open position, we are exposed to fluctuating market prices.
 
    In addition to price risk movements, credit risk is also inherent in our
risk management activities. Our trading and marketing business is also exposed
to counterparty credit risk resulting from a counterparty not fulfilling its
contractual obligations. Our credit policies with regard to our counterparties
attempt to minimize overall credit risk. Our credit procedures include a
thorough review of potential counterparties' financial condition, collateral
requirements under certain circumstances, monitoring of net exposure to each
counterparty and the use of standardized agreements which allow for the netting
of positive and negative exposures associated with each counterparty. Our credit
policy is monitored and administered by a function independent of the trading
and marketing activities.
 
GAS GATHERING AND PROCESSING
 
    Aquila Gas Pipeline (AQP) gathers and processes natural gas and natural gas
liquids. AQP owns and operates a 3,403-mile intrastate gas transmission and
gathering network and four processing plants that extract and sell natural gas
liquids.
 
    Key operating statistics for AQP are presented in the table below.

</TABLE>
 
    Aquila Energy and AQP own 35% of the capital stock of Oasis Pipe Line
Company (Oasis) and have 280 MMcf/d of firm intrastate transportation capacity.
The 600-mile Oasis pipeline system spans the state of Texas and links Aquila's
gathering systems to the Waha, Texas hub and the Katy, Texas hub.
 
                                       8
<PAGE>
    In 1998, AQP entered into a joint venture ownership and operation agreement
with a third party in the Austin Chalk area in Texas to gather and transport the
natural gas produced from specified wells. The sales contract accounted for
approximately 2% of AQP's total natural gas sales in 1998.
 
    In November 1998, we made a proposal to acquire the 18% of AQP's common
stock we do not already own for $8.00 per share. An independent committee of
AQP's Board of Directors is evaluating the proposal.
 
INDEPENDENT POWER PROJECTS
 
    Aquila Energy participates in the ownership and operation of facilities in
the independent and wholesale power generation market. Consistent with the
company's overall strategy to minimize risk through diversification, Aquila
Energy has invested in generation facilities which are geographically diverse
and use a variety of fuels and proven technologies. Additionally, each project
is a producer of competitively priced wholesale power in its geographic region
and has a long-term market for its output. To date, Aquila Energy has made
investments in 17 projects located in seven states and Jamaica, with a total net
ownership of approximately 332 MW of generating capacity. A description and
listing of the power projects appears on page X of this report.
 
    We anticipate further expansion or investment in the independent power
projects business through a newly formed entity focused on structuring and
obtaining control of mid-stream energy assets.
 
III.  INTERNATIONAL
 
    Our international operations are managed separately from the other two
business groups. However, these energy operations are consistent with either the
delivery network or energy merchant strategies. We manage our international
businesses with local management that reports separately to the company. The
normalized contribution to earnings before interest and taxes from international
businesses was 20.8%, 17.0%, and 25.2% of our total for the years ended December
31, 1998, 1997 and 1996, respectively. As of December 31, 1998, approximately
$1,655.0 million of our total assets relate to our international businesses. The
following discussion briefly describes our international businesses.
 
AUSTRALIA
 
    We acquired an effective 49.9% ownership interest in United Energy Limited
(UEL), an electric distribution utility serving 546,000 customers in the state
of Victoria. As part of a management agreement between us and UEL, we manage the
utility for a fee as well as participate in its earnings.
 
    In May 1998, UEL sold 42% of its common stock to the Australian public and
as a result, we recorded a $45.3 million gain. The partial sale to the public
reduced our effective ownership percentage to 29%. Concurrent with UEL's stock
offering, we bought an additional 5% in UEL from another company to bring our
ownership to 34%. Prior to the common stock sale, UEL repaid approximately $101
million in debt notes owed to us. The management agreement between us and UEL
remains in place.
 
    UEL distributes and sells electricity with a majority of its sales earned
from the regulated distribution network business. The regulated distribution
sales and connection charges for access to its distribution system will be
reviewed by the Office of the Regulator General (OGR), with new rates becoming
effective for five years beginning January 1, 2001.
 
                                       9

    The retail market in which UEL operates is being progressively opened to
competition, with all customers becoming contestable by January 1, 2001. The
following table shows the timing of electricity markets opening to competition
in Victoria:

NEW ZEALAND
 
    Through a series of transactions in 1998, we gained control of Power New
Zealand through the purchase of an additional 48% interest for $245 million,
increasing our ownership to 78.6%. Concurrent with this acquisition, we sold our
39.6% interest in New Zealand's WEL Energy Group, which we acquired throughout
1995, 1996, and 1997, and bought out our 21% minority partner in our New Zealand
subsidiary, UtiliCorp N.Z, Inc.
 
    New Zealand's Electricity Industry Reform Act of 1998 requires all the
country's utilities to separate ownership of their lines (network) and supply
(generation and retail) businesses. Power New Zealand, with approximately 90% of
its assets and earnings in the lines area, in November 1998 announced its
intention to remain in the network business and to exit the supply business. It
also agreed to purchase the Wellington-based lines assets of TransAlta New
Zealand Ltd. and to sell to TransAlta its retail electricity business serving
the Auckland area for a net expenditure by Power New Zealand of $238 million.
Because Power New Zealand's name transferred to TransAlta as part of the retail
business TransAlta acquired, the network business became UnitedNetworks Limited
on January 1, 1999. Also in 1998, Power New Zealand agreed to purchase the
electric line assets of neighboring power company TrustPower Limited for
approximately $261 million. The assets became part of a greater network which
includes parts of metropolitan Auckland and other areas in the central and
southern regions of New Zealand's North Island. The TrustPower transaction
closed January 1999. Completion of the TransAlta and TrustPower transactions
created the country's largest electricity distribution network, serving about
468,000 customers.
 
UNITED KINGDOM
 
    We market transportation/shipping and balancing services to gas suppliers.
The fees we collect are priced as a unit per volume consumed. The gas markets in
the United Kingdom are fully competitive with end user customers being able to
choose their gas supplier. The deregulation of the gas markets resulted in many
new retail gas suppliers competing for the approximately 19 million gas
customers in the United Kingdom. As of December 31, 1998, we had approximately 1
million indirect customers, an increase of 900,000 customers since December 31,
1997.
 
    In early 1999 we applied for our electricity supply license. Also this year,
we will begin trading electricity and offering a bundled electricity supply
service to our customers.
 
    We have developed a European expansion plan and anticipate leveraging our UK
operations to begin marketing energy, as deregulation allows, on the European
Continent in 1999.
 
    In June 1998, we paid $25.6 million to a third party to cancel two
take-or-pay contracts and related guarantees effective April 1, 1998, that
required us to take gas at significantly above-market prices until 2005. Between
1995 and 1997, we reserved $19.0 million against the estimated future losses on
these contracts, resulting in a "One Time" net settlement loss of $6.6 million.
 
                                       10
<PAGE>
    In July 1998, we lost a long-standing dispute with one of our previous
suppliers related to a take-or-pay gas supply contract. We were arguing that the
supplier did not make proper deliveries pursuant to the supply contract and
further materially breached the contract. Accordingly we began paying the
supplier the prevailing market prices which were lower than the contract price.
The difference between the two prices accumulated to approximately $38.0
million, an amount we had previously recorded as a liability.
 
    A court ruling required us to pay this $38.0 million price difference along
with interest of $6.8 million that accumulated from the date the contract
invoices were due. This interest payment was recorded as a one-time loss. We are
appealing the court's decision and are seeking recovery of the $44.8 million.
 
CANADA
 
    We own West Kootenay Power Ltd. (WKP), a hydro-electric utility in British
Columbia, Canada. WKP has four hydro-electric generation facilities with a
capacity of 205 megawatts and 962 miles of transmission lines that serve
approximately 86,000 customers in south central British Columbia. WKP generates
about half of its power requirements and purchases the remaining requirements
through power contracts.
 
    The following table summarizes the sales, volumes and customers of WKP.

* COMPOUND ANNUAL GROWTH RATE
 
    WKP is regulated by the British Columbia Utilities Commission. The
Commission approved renewal of the incentive based rate setting mechanism for
1999. This mechanism was the first of its kind for electric utilities in Canada
and was the result of a negotiated settlement with customers and regulators. The
mechanism calls for equal sharing of savings between the customer and WKP if WKP
performs over and above negotiated performance expectations.

COMPETITION
 
DOMESTIC UTILITY OPERATIONS
 
    Our domestic utility businesses operate in a regulated environment despite
various legislative deregulation efforts at the federal level. Industrial and
large commercial customers largely have access to energy sources so some of the
competitive pricing benefits have been transferred to these customers through
open access tariffs relating to transmission lines and pipelines. Without
federal legislation, competition at the retail level cannot form since the rules
will be different in each state. Based on our assessment of retail competition
possibilities, we reduced most retail activities, preferring to wait until the
market develops more fully.
 
ACCOUNTING IMPLICATIONS
 
    We currently record the economic effects of regulation in accordance with
the provisions of Statement of Financial Accounting Standards No. 71 (SFAS 71),
"Accounting for the Effects of Certain Types of Regulation." Accordingly, our
balance sheet reflects certain costs as regulatory assets. We expect that our
rates will continue to be based on historical costs for the foreseeable future.
If we discontinued applying SFAS No. 71, we would make adjustments to the
carrying value of our regulatory assets. Total net regulatory assets at December
31, 1998 were $96.5 million.
 
ENERGY MARKETING
 
    Our energy marketing businesses operate in a fully competitive environment
that rewards participants on price, service and execution. Our energy marketing
businesses compete for customers with some of the largest utility and energy
companies in North America. The industry is premised on large volume sales with
relatively low margins. Companies that operate in this industry must fully
understand the price sensitivity and volatility of commodities. The public
became more aware of some of the risks associated with this industry when a
number of companies announced sudden losses resulting from the June price spike
in electricity. We expect price volatility and we expect events like the June
price spike to recur.

(d) In March 1998, Brooks-Hidalgo Joint Venture's ownership interests in
    its assets were sold.
 
    At December 31, 1998, we owned 35% of the capital stock of Oasis and the
right to transport 280 MMcf/d of natural gas on Oasis' pipeline, plus the
opportunity to utilize excess capacity on an interruptible basis. The Oasis
pipeline is a 600-mile, 36-inch diameter natural gas pipeline which connects
 
                                       17

the Waha, Texas hub to the Katy, Texas hub. The Oasis pipeline has a 1 Bcf/d of
throughput capacity. We use the equity method of accounting for this investment.
 
    At December 31, 1997, AQP owned and/or operated an interest in four natural

(c) Thousands of barrels per day (MBbls/d).
 
(d) This plant is owned and operated by a third party from which AQP receives a
    portion of the NGLs produced from gas AQP delivers to the plant. The plant
    is included in this section for informational purposes to show the gas
    throughput and NGLs production that AQP received utilizing the access to
    this plant.
 
    The availability of natural gas reserves to AQP depends on their development
in the area served by its pipelines and on AQP's ability to purchase gas
currently sold to or transported through other pipelines. The development of
additional gas reserves will be affected by many factors including the prices of
natural gas and crude oil, exploration and development costs and the presence of
natural gas reserves in the areas served by AQP's systems.

                          FINANCIAL STATEMENT SCHEDULE
 
To the Board of Directors and Shareholders of UtiliCorp United Inc.:
 
    We have audited in accordance with generally accepted auditing standards, 
the consolidated financial statements for 1998, 1997 and 1996 described on 
page 60 of UtiliCorp United Inc.'s Annual Report to shareholders, which is 
incorporated by reference in this Form 10-K, and have issued our report 
thereon dated February 1, 1999. Our audits were made for the purpose of 
forming an opinion on those statements taken as a whole. The Financial 
Statement Schedule listed in Item 14(a)2 is the responsibility of the 
company's management and is presented for the purposes of complying with the 
Securities and Exchange Commission's rules and is not part of the basic 
financial statements. This schedule has been subjected to the auditing 
procedures applied in the audit of the basic consolidated financial 
statements and, in our opinion, fairly states in all material respects the 
financial data required to be set forth therein in relation to the basic 
consolidated financial statements taken as a whole.

FINANCIAL REVIEW
- --------------------------------------------------------------------------------
Consolidated Operations

This review of 1998 performance is organized by business segments, reflecting
the way we manage our businesses. Each business unit leader is responsible for
operating results expressed as earnings before interest and taxes (EBIT).
Therefore each segment discussion focuses on the factors affecting EBIT.

      We make all decisions on finance, dividends and taxes at the corporate
level. We discuss those topics separately on a consolidated basis. Our main
financial performance objectives are: -

(a)   In April 1998, we were ordered by the Missouri Public Service Commission
      to reduce rates by $22.7 million annually, or $16.3 million prorated in
      1998.
(b)   Natural gas liquids prices and production declined 26% and 32%,
      respectively.
(c)   Winter temperatures as measured by heating degree-days were off 15%,
      partially offset by warmer summer temperatures.
(d)   Our International growth came from New Zealand and the United Kingdom.
(e)   Off-system volume growth, customer additions and the weather recovery plan
      were all contributors.
(f)   Aquila's term business came on strong, signing over 700 transactions in
      1998.

NON-RECURRING ITEMS
      Our normalized earnings before interest and taxes (EBIT) for the three
years ended December 31, 1998 were affected by several items that we expect will
not have a continuing impact on UtiliCorp's financial position or results from
operations. The table below summarizes the effect of non-recurring items on
EBIT.

(a)   In 1997, we received $53.0 million from Kansas City Power & Light Company
      as a merger termination fee. In 1996, we expensed all previously deferred
      merger costs and recorded an $11.0 million charge against earnings.
(b)   In 1996, we recorded a gain from a sales lease on a power project. The
      gain was partially offset by certain restructuring reserves related to
      changes in power project agreements. The result of these items increased
      EBIT $20.9 million.
(c)   In 1998, we recorded a $27.7 million provision for impaired assets
      relating to certain retail gas marketing assets, termination of EnergyOne
      L.L.C., and the write-off of an independent power project. In 1997, we
      recorded a provision for impaired assets of $26.5 million related to
      certain technology and royalty assets.
(d)   In 1998, we settled two above-market gas contracts at a net loss of $6.6
      million. In addition, a judgement against us on a disputed gas supply
      contract requires us to record $6.8 million in interest related to the
      contract. In 1997, we recorded a $6.5 million reserve primarily for
      unfavorable gas supply contracts in the United Kingdom.
(e)   In 1998, United Energy Limited (UEL) sold 42% of its common stock to the
      public in Australia. UtiliCorp recorded a $45.3 million gain from the
      sale.

      We use the term "normalized EBIT" to describe our recurring earnings
before interest and taxes excluding non- recurring items. The term is not meant
to replace actual EBIT or other performance measures used under generally
accepted accounting principles.

GROSS PROFIT

Gross profit from Regulated Businesses in 1998 was $5.1 million more than in
1997. This is due to a 2.6% increase in utility customers, higher customer usage
and energy sales that together increased gross profit by $29.2 million.
Partially offsetting this increase were the impact of mild weather, which
reduced gross profit by $16.6 million, and the effects of a rate reduction in
Missouri. The rate reduction became effective in April and reduced gross profit
by $12.0 million. The Missouri rate order also increased depreciation expense by
$4.3 million. Winter weather in 1998 was 15% warmer than normal.

Gross profit in 1997 increased $15.0 million compared to 1996. This was
primarily due to customer growth and normal weather in 1997. In 1996, winter
weather was 8% warmer than normal.

OPERATING EXPENSES

Operating expenses decreased $5.1 million in 1998 compared to 1997. To recover
from the effects of mild winter weather in the first quarter, we began a cost
reduction program that reduced expenses by $15.7 million. This savings was
partially offset by higher transmission fees and payroll and benefit increases.

Operating expenses increased $19.1 million in 1997 compared to 1996. This
reflects inflation, greater allocation of expenses from Corporate, and increases
in property taxes and depreciation from utility plant additions.

GROSS PROFIT

Gross profit in 1998 declined $23.0 million compared to 1997. The decrease
reflects a $38.3 million drop in gross profit from Aquila Gas Pipeline (AQP)
that was partially offset by a $15.3 million increase from Energy Marketing.
AQP's results in 1998 were lower due to a 26% decrease in NGL prices and a 32%
decrease in NGL production. This combination reduced AQP's 1998 gross profit by
$25 million. NGL prices are closely tied to crude oil prices, which declined
significantly in 1998. As oil prices declined, drilling activity in the Austin
Chalk region of Texas, AQP's main gathering area, was limited to deep gas wells
which produce less liquid. NGL production also declined because AQP voluntarily
bypassed certain volumes due to low prices. The NGL price declines were largely
shared with producers as a majority of AQP's contracts are structured as percent
of production. We do not expect NGL prices or production to improve in 1999.

     Gross profit from energy marketing increased 14% in 1998 compared to 1997,
primarily due to the following:

     -    Increased gross margin from electricity, partially offset by lower gas
          marketing margins.
     -    An 86% increase in electricity marketing volumes as this market
          segment continued to expand.
     -    A 131% increase in gross margin from longer-term contracts (generally
          those of more than a year).
     -    Better results from commercial and industrial segments, achieved by
          increased focus on existing operations.

     In June 1998, the price of electricity varied widely as the market reacted
to a power shortage caused by several power plant outages and low reserve
margins. During June, electricity prices fluctuated between $30 and $7,500 per
megawatt-hour. This caused many market participants to panic as they covered
open short positions with high-priced electricity. In addition, some firms did
not honor their contract obligations, causing others to replace the lost
electricity with higher-priced supply. We did not incur net losses from June's
unusual pricing patterns. Assessing credit and counterparty risk is a
cornerstone principle of our risk management system of internal control. This is
why our credit policy is administered by a function that is independent from
trading and sales.

     Gross profit in 1997 increased $41.4 million or 22% compared to 1996. This
was due to a 94% and 905% increase in gas and electricity marketing volumes
which resulted in $26.2 million and $9.0 million, respectively, in additional
margin. These volumetric increases reflect the impact of an aggressive expansion
program.

     Gross profit from AQP decreased $6.9 million in 1997 compared to 1996. NGL
production volumes declined because of leaner gas streams, lower NGL prices and
reduced gas marketing results. In 1997, NGL production volumes were down 10% and
prices were down 3% compared to 1996. The leaner gas streams were due to
generally deeper drilling in the Austin Chalk area.

     Gross profit from small commercial and industrial gas marketing increased
$13.1 million in 1997 over 1996 as these businesses were assimilated into Aquila
from another business segment. The increase was due to the expansion of sales to
industrial and commercial customers. In 1996, the retail business had fixed
price sales contracts against variable purchase contracts when the price of
natural gas escalated. Although the retail business improved in 1997, it still
had a net EBIT loss of $5.1 million in 1997 compared to $13.1 million in 1996.

OPERATING EXPENSES

Operating expenses in 1998 were $11.2 million higher than in 1997, after
normalizing for non-recurring items in both periods. Operating expenses
increased primarily as a result of additional staffing needed to support the
growth of the business.

     Operating expenses increased $12.3 million in 1997 compared to 1996, after
normalizing for the provision for asset impairment. The increase reflects higher
staffing costs to support Aquila's aggressive growth strategy and rapid increase
in marketing volumes.

EQUITY IN EARNINGS

Equity in earnings increased $4.0 million in 1998 compared to 1997, primarily
because we sold part of our ownership in an independent power project for a $3.6
million gain. Equity in earnings increased $2.8 million in 1997 compared to
1996, after normalizing for the gain on sales lease of $20.9 million. The
increase was primarily due to innovative gas tolling and dispatch arrangements
at one of the independent power projects and increased production from another
project.

The normalized EBIT by country is discussed below.

GROSS PROFIT

International gross profit increased $31.9 million in 1998 compared to 1997.
This increase is primarily due to the consolidation of UnitedNetworks, beginning
in October 1998, because of our increased level of ownership. Gross profit from
UnitedNetworks was $23.8 million. Prior to October 1998, our New Zealand
investments were accounted for under the equity method and shown in "Equity
earnings in subsidiaries and partnerships." Gross profit from the United Kingdom
(U.K.) increased $14.8 million in 1998 after adjusting for non-recurring items.
This is due to an increase in trading and transportation margin resulting from
the execution of our wholesale services strategy. Our indirect customers in the
U.K. increased from 97,000 to more than 1 million in 1998. We bought out two
above-market gas supply contracts in 1998 for $25.6 million. The contracts had
hampered profitability in the 1998 first quarter and in 1997. A reserve we set
up in advance covered $19.0 million of this amount.

     Gross profit from Canada was down $5.2 million in 1998 compared to 1997 due
to milder winter weather and higher power costs.

                                                                              33
<PAGE>

     United Kingdom gross profit was $7.2 million lower in 1997 compared to
1996, after adjusting for non-recurring items. This mainly reflects two
high-cost gas supply contracts that took effect in October 1996.

OPERATING EXPENSES

Operating expenses increased $15.9 million in 1998 compared to 1997. This was
due to a $15.8 million increase from New Zealand related to the consolidation of
UnitedNetworks in October 1998. 

     Operating expenses in 1997 were $4.6 million lower than in 1996 due to 
higher currency values in most of our foreign markets in 1996 and higher 
expatriate expenses in 1996 due to initial relocation costs.

Initial Public Offering--United Energy Limited

In May 1998, United Energy Limited (UEL) sold 42% of its common stock to the
public. As a result, we recorded a $45.3 million gain. Also, our ownership
percentage in UEL reduced from 49.9% to 29%. Concurrent with UEL's stock
offering, we bought an additional 5% in UEL from another company. Prior to the
common stock sale, UEL repaid approximately $101 million in debt notes. The
effect of this transaction reduced our ownership position, but was substantially
offset by higher earnings at UEL as a result of lower interest costs and
application of the $101 million to reduce our debt.

COMPETITION IN AUSTRALIA

The State of Victoria is deregulating its electricity market in stages.
Currently, customers with yearly usage above 160 megawatt-hours (industrial and
large commercial customers) can choose their retail electricity suppliers. After
January 1, 2001, all UEL customers will be able to choose their retail
electricity suppliers. A majority of UEL's gross margin comes from distribution
line charges that would not be affected by this customer choice.

NEW ZEALAND ACQUISITIONS AND DISPOSITIONS

In 1998, through a series of transactions we gained control of Power New Zealand
Limited (PNZ) through the purchase of an additional 48% interest. We bought the
additional 48% for $245 million, bringing our total ownership interest in PNZ to
79%.

     As part of New Zealand's Electricity Industry Reform Act of 1998, electric
companies were required to separate the ownership of their lines (distribution)
and supply (generation and retail) businesses and choose to become either a
lines company or a supply company. This requires selling any other piece of the
business not in the chosen segment. PNZ decided to become a lines company and as
a result, it has sold its retail business to TransAlta New Zealand Ltd. In
addition, PNZ bought TransAlta's lines business, paying a net $238 million after
the two transactions. PNZ also acquired a lines business from TrustPower for
$261 million, effective January 1999. As part of the sale of PNZ's retail
business, PNZ sold the Power New Zealand name to TransAlta. Our network business
in New Zealand is now known as UnitedNetworks Limited. We expect that all of
these transactions will increase the EBIT contribution from New Zealand by $55
million in 1999 compared to 1998.

CORPORATE MATTERS

CORPORATE AND OTHER

The table below summarizes the corporate and other EBIT for the three years
ended December 31, 1998. Corporate primarily contains the retained costs of the
company that are not allocated to the business units and the net losses from the
company's investment in EnergyOne, L.L.C.

</TABLE>

     Corporate and other normalized EBIT increased by $7.6 million due to the
elimination of losses from our EnergyOne partnership with PECO Energy Company.
The partnership was terminated in April 1998. Corporate and other normalized
EBIT improved by $25.2 million in 1997 compared to 1996 due to the elimination
of certain corporate activities and transfer of capital costs associated with
new information systems recorded at corporate, but allocated to business units.

COMPETITION

DOMESTIC UTILITY OPERATIONS. Our domestic utility businesses operate
in a regulated environment despite various legislative efforts at the federal
level. Industrial and large commercial customers largely have access to energy
sources so some of the competitive pricing benefits have been transferred to
these customers through open access tariffs relating to transmission lines and
pipelines. Without federal legislation, competition at the retail level cannot
form since the rules will be different in each state. As a result of our
assessment of retail competition possibilities, we reduced most retail
activities until the market more fully develops.

ACCOUNTING IMPLICATIONS. We currently record the economic effects of regulation
in accordance with the provisions of Statement of Financial Accounting Standards
No. 71 (SFAS No. 71), "Accounting for the Effects of Certain Types of
Regulation," and accordingly our balance sheet reflects certain costs as
regulatory assets. We expect that our rates will continue to be based on
historical costs for the foreseeable future. If we discontinued applying SFAS
No. 71, we would make adjustments to the carrying value of our regulatory
assets. Total net regulatory assets at December 31, 1998 were $96.5 million.

ENERGY MARKETING. Our energy marketing businesses operate in a fully competitive
environment that rewards participants on price, service and execution. Our
energy marketing businesses compete for customers with some of the largest
utility and energy companies in North America. The industry is premised on large
volume sales with relatively low margins. Companies that operate in this
industry must fully understand the price sensitivity and volatility of
commodities. The public became more aware of some of the risks associated with
this industry when a number of companies announced sudden losses resulting from
the June price spike in electricity. We expect price volatility and we expect
events like the June price spike to recur.

ENVIRONMENTAL MATTERS

We have been named a potentially responsible party (PRP) at three PCB disposal
facilities. Our combined cleanup expenditures have been less than $1 million to
date. We anticipate that future expenditures on these sites will not be
significant.

     We also own or once operated 29 former manufactured gas plants which may
require some form of environmental remediation. See Note 15 to the Consolidated
Financial Statements for further discussion of this topic.

     In December 1996, the EPA published its final rule for nitrous oxide (NOx)
emissions under the requirements of the Clean Air Act Amendments of 1990. The
new NOx regulations will affect one of our power plants by requiring us to
install additional emissions controls by January 1, 2000. In October 1998, the
EPA published new air quality standards to further reduce the emission of NOx.
These more strict standards will require us to install new equipment on our
baseload coal units in Missouri that we estimate will cost $35 million. The
ultimate cost is under debate and subject to change. The new standards as
written are effective in May 2003.

YEAR 2000 ISSUES

Our computer systems as presently configured may not recognize the two-digit
date of "00" as the year 2000. This could cause systems to shut down or
malfunction. In order to address potential year 2000 issues, we established a
Year 2000 Project Office to coordinate efforts in our operating units to ensure
that computer systems and applications will function properly beyond 1999.

     Many of our information systems and related software are already year
2000-ready. We have installed a major new software system that includes
financial, customer information (in certain locations) and support systems. We
also expect to have our new customer information system fully installed by
mid-1999. We expect these projects, known internally as "Project BTU," to
replace at least 80% of potentially affected software. We began Project BTU in
1995 to update our internal support systems and position us to serve our
customers better. Total expenditures for the new systems will be approximately
$186.0 million. Of this amount, to date we have spent $143.9 million.

 We are also coordinating the identification and testing of remaining software,
information technology devices, embedded technology systems, and services
provided by third parties that may be affected by the year 2000. We completed
the identification and testing phases in 1998 and will begin remediation in
1999. At this time, we do not have a contingency plan to address unforeseen
issues, but we expect the Project Office to have one by mid-1999. We are
currently preparing budgets and estimates of

                                                                              35
<PAGE>

remediation costs for this portion of our year 2000 remediation of
mission-critical systems. We expect the remediation of certain
non-mission-critical systems to extend beyond 1999. We expect to spend
approximately $2.3 million in total remediation costs outside of Project BTU.

     We are evaluating the impact of internal and external year 2000 issues on
our operations to develop a model on which to base contingency planning. We are
conducting internal evaluations and discussions with other utilities, as well as
participating in industry-wide efforts being conducted by the North American
Electric Reliability Council and the Gas Industry Standards Board, to prepare
for this issue and ensure the company's efforts are in line with the rest of the
industry.

     For complete system changeouts, we capitalize cost under guidelines
described in Emerging Issues Task Force (EITF) 97-13, "Accounting for Costs
Incurred in Connection with a Consulting Contract or an Internal Project that
Combines Business Process Reengineering and Information Technology
Transformation." For programming fixes on existing systems, we record these
costs as maintenance expense.

MARKET RISK--TRADING

     We are exposed to market risk, including changes in commodity prices,
interest rates and currency exchange rates. To manage the volatility relating to
these exposures, we enter into various derivative transactions in accordance
with our policy approved by the Board of Directors. We routinely enter into
financial instrument contracts to position the portfolio. Our trading portfolios
consist of physical and financial natural gas, electricity, coal and interest
rate contracts. These contracts take many forms including futures, forwards,
swaps and options.

     We measure the risk in our trading portfolio using value-at-risk
methodologies, to simulate forward price curves in the energy markets and
estimate the size of future potential losses. The quantification of market risk
using value-at-risk methodologies provides a consistent measure of risk across
diverse energy markets and products. The use of this method requires a number of
key assumptions, such as:

     -    Selection of a confidence level (we use 95%).

     -    Estimated holding period (we use three days).

     -    Use of historical estimates of volatility and correlation with recent
          activity more heavily weighted.

     At December 31, 1998, our value at risk was:

<TABLE>
<CAPTION>
In millions
- ------------------------------------
<S>                             <C>
Electricity                     $ .7
Natural gas                      2.2
- ------------------------------------
</TABLE>


     The average value at risk for all commodities during 1998 was $3.8 million.

     We also use additional risk control mechanisms such as stress testing,
daily loss limits and commodity position limits, as well as daily monitoring of
the trading activities by an independent function.

     Although interest and foreign currency risks are monitored within the
commodity portfolios and value-at-risk calculation, separate portfolios for
interest and foreign currency risks do not exist. The value of our commodity
portfolios are impacted by interest rates as the portfolio is valued using an
estimated interest discount factor to December 31, 1998. We often sell Canadian
sourced natural gas into the U.S. markets accepting U.S. dollars from customers,
but paying Canadian dollars to suppliers. This exposes our portfolio to currency
risk. We currently do not hedge this exposure.

     The table below shows the expected cash flows associated with the interest
rate financial instruments at December 31, 1998.

MARKET RISK--NON-TRADING

     We are also exposed to commodity price changes outside of price risk
management activities. The following table summarizes these exposures on an EBIT
basis.

CURRENCY RATE EXPOSURE

     We do not currently hedge our net investment in foreign operations. As a
result, the foreign denominated assets and liabilities fluctuate in value.
Historically, our net exposure to changes in foreign currency has been limited
as the company's foreign investments were financed through foreign debt.

     if the change occurred uniformly over the entire year, based on 1998
     financial results.

INTEREST RATE EXPOSURE

     We have approximately $446.5 million of variable rate debt as of December
31, 1998. A 100-basis-point change in each debt's benchmark rate would affect
net income by approximately $2.7 million. We hedged approximately $316 million
of variable debt with fixed rate financial instruments.

LIQUIDITY AND CAPITAL RESOURCES

     Our cash requirements arise primarily from continued growth, electric and
gas utility construction programs, non-regulated investment opportunities and
Aquila Energy's working capital requirements. Our ability to attract the
necessary financial capital at reasonable terms is critical to our overall plan.
Historically, we have financed acquisitions and investments initially with
short-term debt and subsequently funded them with an appropriate mix of common
equity and long-term debt securities, depending on prevailing market conditions.

     A primary source of short-term cash has been bank loans which aggregated
$235.6 million, $113.8 million and $202.0 million at December 31, 1998, 1997 and
1996, respectively. We can also issue up to $150 million of commercial paper
supported by a $250 million committed revolving credit agreement. The credit
agreement expires in December 2000 and allows for the issuance of notes at
interest rates based on various money market rates. We had no commercial paper
borrowings at December 31, 1998 and 1997.

     To maintain flexibility in our capital structure and to take advantage of
favorable short-term rates, we sell our accounts receivable under two programs
to fund a portion of our short-term cash requirements. The level of funding
available from these programs is limited to $280 million and the amount
fluctuates seasonally. We had sold approximately $248 million under these
programs at December 31, 1998. These programs were fully utilized at December
31, 1997 and 1996.

     In 1998, certain customers prepaid $185.2 million for future gas supplies.
We used this cash to reduce short-term debt. In the future we will incur
short-term debt to buy gas over the contract period.

     In 1998 we sold 12.98 million shares of our common stock at $23.41 per
share, net of underwriting costs. The $304 million in net proceeds was used to
reduce domestic short-term debt and accounts receivable sales programs. Our
capital structure consisted of the following components at December 31, 1998 and
1997.

</TABLE>

     We have approximately 2.2 million treasury shares as of December 31, 1998,
that we expect to issue to our stock plans in 1999. Our dividend payout ratio
was 73% in 1998 (annualized dividends of $1.20 divided by basic EPS of $1.65).
We expect our EPS growth to be approximately four times our dividend growth.
This should reduce our payout ratio to about 50-60% over the next five years.
The combination of higher earnings growth compared to dividends and the expected
reissue of treasury stock will increase the equity component in our capital
structure in the future.


                                                                              37

CASH REQUIREMENTS

Future cash requirements include utility plant additions, required redemptions
of long-term securities, and acquisition opportunities. We estimate expenditures
over the next three years for these activities, excluding acquisitions, will be
as follows:

</TABLE>

     Aquila Energy plans to build a 500-megawatt combined cycle generation
plant, initially to serve the capacity needs of our Regulated Businesses
beginning in June 2001. The new plant is expected to cost approximately $241
million.

     We expect to refinance our maturing debt issues in 1999 and will consider
refinancing or restructuring certain higher coupon debt in 1999 if market
conditions warrant. We believe that our available cash resources from both
operating cash flows and borrowing capacity will be adequate to meet our
anticipated future cash requirements.

SIGNIFICANT BALANCE SHEET MOVEMENTS

Total assets increased $878 million in 1998 compared to 1997. This increase is
primarily due to the following:

     -    We invested approximately $609.7 million in New Zealand in 1998 to
          obtain control of UnitedNetworks, at the time transitioning to become
          a lines business, and to acquire an additional lines business. The
          increase also reflects the buyout of a partner in Australia.

     -    Assets of the company reflect UnitedNetworks on a consolidated basis
          for 1998, versus as an equity investment in 1997.

     -    We purchased 47 Bcf of gas held in storage at December 31, 1998 that
          will be used in Aquila's gas marketing business.

     -    Price risk management assets (current and long-term) increased $105.6
          million, reflecting the expansion of Aquila's business in 1998.

     Total liabilities increased in 1998 by $595.3 million and common
shareowners' equity increased by $282.7 million in 1998 due to the following:

     -    Long-term debt increased by $116.4 million in 1998 due primarily to
          the acquisition activity in New Zealand, partially offset by maturing
          debt and the application of $101 million against debt that we received
          from UEL.

     -    Short-term debt increased $121.8 million in 1998 due to the
          acquisition activity in New Zealand.

     -    Minority interests increased by $92.6 million in 1998 due to New
          Zealand acquisition activity.

     -    Price risk management liabilities increased $206.4 million, reflecting
          the expansion of Aquila's business in 1998.

     -    Common shareowners' equity increased by $282.7 million due to the sale
          of 12.98 million common shares, partially offset by treasury shares
          held.

AQUILA GAS PIPELINE BUYOUT PROPOSAL

In November 1998, we made a proposal to acquire the 18% of AQP's common stock we
do not already own for $8.00 per share. An independent committee of AQP'S Board
of Directors is evaluating the proposal.

NEW ACCOUNTING STANDARDS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" (SFAS 133). SFAS 133 established accounting and
reporting standards for derivative instruments and hedging activities requiring
that every derivative instrument, including certain derivative instruments
embedded in other contracts, be recorded in the balance sheet as either an asset
or liability measured at its fair value. The Statement requires that changes in
the derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. Special accounting for qualifying hedges
allows a derivative's gains and losses to offset related results on the hedged
item in the income statement, and requires that the company must formally
document, designate, and assess the effectiveness of transactions that receive
hedge accounting. SFAS 133 must be adopted for fiscal years beginning after
June 15, 1999.

     SFAS 133 will impact our hedging activities at Aquila Energy and Aquila Gas
Pipeline, corporate treasury activities, foreign subsidiary trading activities,
and power trading contracts. We have not quantified this impact.

     In 1998 the Emerging Issues Task Force (EITF) agreed to require companies
to mark to market their energy trading activities beginning in 1999. We already
use the mark-to-market method of accounting for domestic trading activities.
However, we engage in certain trading activities internationally for which we do
not use mark-to-market accounting. We are evaluating the impact this will have
on our financial results. At this time we cannot estimate that impact.

In the next few years, the company anticipates that the level of inflation, if
moderate, will not have a significant effect on operations or acquisition
activity.

FORWARD-LOOKING INFORMATION

This report contains forward-looking information. Such statements involve risks
and uncertainties and there are certain important factors that could cause
actual results to differ materially from those anticipated. Some of the
important factors which could cause actual results to differ materially from
those anticipated include:

     -    Weather, which can affect results significantly to the extent that
          temperatures differ from normal. Both our utility and energy merchant
          businesses are weather-sensitive.

     -    The timing and extent of changes in energy commodity prices and
          interest rates.

     -    The pace and degree of regulatory changes in the U.S. and abroad.

     -    NGL prices and volumes, which are particularly volatile and difficult
          to predict.

     -    The pace of well connections to our gathering system.

     -    The value of the U.S. dollar relative to the British pound, Canadian
          dollar, Australian dollar and New Zealand dollar.

     -    The continued expansion of the electric power markets and development
          of liquid term markets.

     -    Pending rate proceedings.

NOTE 1:

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

UtiliCorp United Inc. is an international energy and energy solutions provider
headquartered in Kansas City, Missouri. We operate lines of business in the
following financial reporting segments: Regulated Businesses and Aquila Energy
(Aquila). Through locally based managements we operate our international
businesses as stand-alone companies or investments. Together these comprise the
International segment.

     The main activity of Regulated Businesses is operating domestic utilities
that distribute and transmit electricity and natural gas. Our generation
facilities produce electricity in the U.S., primarily for our own distribution
system. We sell the rest of the output outside our service areas. We also
provide appliance maintenance and repair and market natural gas. Aquila markets
wholesale energy, gathers, transports and processes natural gas and gas liquids,
and holds interests in independent power projects. Aquila Energy Corporation is
a wholly-owned subsidiary of UtiliCorp. Aquila Gas Pipeline Corporation (AGP),
82%-owned by Aquila, operates the gas gathering and processing businesses,
located in Texas and Oklahoma.

     Our utilities are in eight states, one Canadian province and New Zealand.
We market natural gas and electricity throughout the U.S. and in parts of
Canada, and market natural gas in the United Kingdom (U.K.). We also have
various investments in Australia and Jamaica.

USE OF ESTIMATES

We prepared these financial statements in conformity with generally accepted
accounting principles and made certain estimates and assumptions that affect the
reported amounts of assets and liabilities. Our estimates and assumptions affect
the disclosure of contingent assets and liabilities in this report and reported
amounts of sales and expenses during the reporting period. Actual results could
differ from those estimates. Our accounting policies conform to generally
accepted accounting principles.

PRINCIPLES OF CONSOLIDATION

Our consolidated financial statements include all of UtiliCorps operating
divisions and majority-owned subsidiaries. We use equity accounting for
investments of which we own between 20% and 50%. We eliminate any significant
inter-company accounts and transactions.

PROPERTY, PLANT AND EQUIPMENT

We show property, plant and equipment at cost. We expense repair and maintenance
costs as incurred. Depreciation is provided on a straight-line basis over the
estimated lives for utility plant by applying composite average annual rates.
These range from 2.1% to 4.2%, as approved by regulatory authorities. When
property is replaced, removed or abandoned, its cost, together with the costs of
removal less salvage, is charged to accumulated depreciation. We depreciate
gathering, processing and other energy related property using a composite
average annual rate of 4.0%. We depreciate remaining non-regulated property,
plant and equipment on a straight-line basis over their estimated lives, ranging
from three to 50 years.

SALES RECOGNITION

We recognize sales as products and services are delivered, except for trading
and energy marketing activities. These are discussed below.

     For North American trading and energy marketing activities, we use the
mark-to-market method of accounting. Under that method, trading and energy
marketing activities are recorded at fair value, net of future servicing costs
and reserves. When the portfolio's market value changes (primarily due to newly
originated transactions and the effect of price changes) the change is
recognized as gains or losses in the period of change within the sales caption.
We record the resulting unrealized gains and losses as price risk management
assets and liabilities.

INCOME TAXES

Our financial statements use the liability method to reflect income taxes. To
estimate deferred tax assets and liabilities we apply current tax regulations at
the end of a reporting period to the cumulative temporary differences between
the tax bases of assets and liabilities and their reported amounts in the
financial statements. We amortize deferred investment tax credits over the lives
of the related properties.

CASH EQUIVALENTS AND CASH FLOW INFORMATION
Cash includes cash in banks and temporary investments with an original maturity
of three months or less. As of December 31, 1998, 1997 and 1996, our cash held
in foreign countries was $41.7 million, $74.5 million and $86.7 million,
respectively.

     Cash payments for interest, taxes and supplemental disclosures relating to
acquisition activities are presented below:

EARNINGS PER COMMON SHARE*

The table below shows how we calculated diluted earnings per share and diluted
shares outstanding. Basic earnings per share and basic weighted average shares
are the starting point in calculating the dilutive measures. To calculate basic
earnings per share, divide earnings available into weighted average shares
without adjusting for dilutive items.

CURRENCY ADJUSTMENTS

We translate the financial statements of our foreign subsidiaries and 
operations into U.S. dollars using the average monthly exchange rate during 
the period for income statement items. We use the year-end exchange rate for 
balance sheet items. When translating foreign currency-based assets and 
liabilities to U.S. dollars, we show any differences between accounts as 
translation adjustments in common shareowners' equity. For income statement 
accounts we show all changes in foreign currency relative to the U.S. dollar 
within the consolidated statements of income.

SOFTWARE COSTS

We capitalize the costs of internally-developed software that qualifies for
capitalization under generally accepted accounting principles. We expense those
costs that do not qualify. Typical capitalized costs include software coding and
testing. Typical expensed costs include training and data conversion costs.

STOCK-BASED COMPENSATION

We issue stock options to employees from time to time and account for these 
options under Accounting Principles Board Opinion No. 25 (APB 25). All stock 
options issued are granted at the common stock's current market price. This 
means we record no compensation expense related to stock options. We also 
offer employees a 15% discount from the market price of our common stock.

     Since we record options and discounts under APB 25, we must disclose the 
proforma compensation expense and earnings per share (dilutive method) as if 
we reflected the estimated fair value of options and discounts as 
compensation at the date of grant or issue. For the years ended December 31, 
1998, 1997, and 1996, our proforma compensation expense would be $10.1 million, 
$4.9 million and $1.5 million, respectively. Our proforma earnings per share 
would have been reduced by $.07, $.03, and $.01 for the years ended 
December 31, 1998, 1997 and 1996, respectively.

                                                                              45

NOTE 2:

A. TRADING ACTIVITIES:
PRICE RISK MANAGEMENT ACTIVITIES

We trade energy commodity contracts daily. Our trading activities attempt to
match our portfolio of physical and financial contracts to current or
anticipated market conditions. Within the trading portfolio, we take certain
positions to hedge physical sale or purchase contracts and we take certain
positions to take advantage of market trends and conditions. We record most
energy contracts--both physical and financial--at fair market value. Changes in
value are reflected in the consolidated statement of income. We use all forms of
financial instruments including futures, forwards, swaps and options. Each 
type of financial instrument involves different risks. We believe financial 
instruments help us manage our exposure to changes in market prices and take 
advantage of selected arbitrage opportunities.

     We refer to these transactions as price risk management activities.

MARKET RISK

The company's price risk management activities involve offering fixed price
commitments into the future. The contractual amounts and terms of these
financial instruments at December 31, 1998, are shown below:

<TABLE>

- ------------------------------------------------------------------------------------------------------------
</TABLE>

     Although we attempt to balance our physical and financial contracts in
terms of quantities and contract performance, net open positions typically
exist. We will at times create a net open position or allow a net open position
to continue when we believe that future price movements will increase the
portfolio's value. To the extent we have an open position, we are exposed to
fluctuating market prices that may adversely impact our financial position or
results from operations.

     We measure the risk in our trading portfolio using value-at-risk
methodologies, to simulate forward price curves in the energy markets and
estimate the size of future potential losses. The quantification of market risk
using value-at-risk methodologies provides a consistent measure of risk across
diverse energy markets and products. The use of this method requires a number of
key assumptions, such as:

     -    Selection of a confidence level (we use 95%).

     -    Estimated holding period (we use three days).

     -    Use of historical estimates of volatility and correlation with recent
          activity more heavily weighted.

 At December 31, 1998, our value at risk was:

Natural gas                           2.2
- ----------------------------------------------
</TABLE>

     We also use additional risk control mechanisms such as stress testing,
daily loss limits and commodity position limits as well as daily monitoring of
the trading activities by an independent function.

MARKET VALUATION

The market prices used to value price risk management activities reflect our
best estimate of market prices considering various factors, including closing
exchange and over-the-counter quotations, time value of money and price
volatility factors underlying the commitments. We adjust market prices to
reflect the potential impact of liquidating our position in an orderly manner
over a reasonable period of time under present market conditions.

     We consider a number of risks and costs associated with the future
contractual commitments included in our energy portfolio, including credit risks
associated with the financial condition of counterparties, product

location (basis) differentials and other risks which our policy dictates. The
value of all forward contracts is discounted to December 31, 1998 using an
estimated rate. We continuously monitor the portfolio and value it daily based
on present market conditions. The following table displays the market values of
energy transactions at December 31, 1998 and 1997 and the average value for the
year ended December 31, 1998 and 1997:

</TABLE>


     Future changes in the creditworthiness of our counterparties change the
value of our portfolio. We adjust the value of contracts and set dollar limits
with counterparties based on our assessment of their credit quality.

     As of December 31, 1998, the future cash flow requirements, net of margin
deposits, related to these financial instruments were $15.1 million. Margin
deposits are required on certain financial instruments to address significant
fluctuations in market prices.

     The value of price risk management assets is concentrated into three
contracts representing 36% of total asset value of the portfolio. This
concentration of customers may impact the companys 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.

B. NON-TRADING ACTIVITIES--HEDGING
INSTRUMENTS

We enter into forwards, futures and other contracts related to our commodity
businesses solely to hedge future production. The estimated fair value and cash
flow requirements for these financial instruments are based on the market prices
in effect at the financial statement date and do not necessarily reflect our
entire trading portfolio.

                                                                              47

an expense in the consolidated statements of income. Our consolidated statements
of income reflect fees associated with these sales of (in millions) $16.0 in
1998, $15.2 in 1997, and $12.2 in 1996.

CUMULATIVE EFFECT OF SOFTWARE
ACCOUNTING CHANGE

In 1997, we changed our method of accounting for internally developed software
costs to conform with the new requirements of an accounting standard that became
effective November 20, 1997. This accounting change reduced 1997 net income by
$4.8 million and is shown in our consolidated statement of income as a
cumulative effect of software accounting change.

ASSET IMPAIRMENTS

We have adjusted the reported value of certain assets over the last three years.
Although it was a requirement that assets reflect realizable values, it was not
until the passage of Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets 
to be Disposed Of" (SFAS 121), that impairment provisions were determined on a
consistent basis and methodology. The table below summarizes the impairment
provisions we have recorded since 1996 and the related reasons.

(a)  In June 1998, we revised our strategic plan to curtail our retail
     activities. This revised strategy diminished the value of certain retail
     assets and required an impairment provision to be recorded.
(b)  In April 1998, we agreed with our partner to dissolve our partnership due
     to unfavorable market conditions and unsatisfactory execution of its
     strategy. As a result of this decision, the recorded value of EnergyOne,
     L.L.C. became overstated related to liquidation values and an impairment
     provision was recorded.
(c)  In June 1998, we concluded that the cash flows from a power project would
     not be sufficient to recover its recorded value. This project was exploring
     certain methods to enhance cash flows, such as fuel mix changes, but based
     on our analysis, we concluded that no viable alternatives existed to
     improve operations. We recorded an impairment based on this analysis.
(d)  In 1997, we reduced the carrying value of royalty interests that are tied
     to the drilling success of some properties we sold in 1995. Based on
     information from the company we sold the properties to, we concluded that
     an impairment charge was necessary.
(e)  In 1997, we wrote off our investment in a technology joint venture
     organized to develop energy related innovations. When no marketable
     products were developed we reassessed the value of this investment and
     determined that future cash flows, if any, would not recover invested
     costs.

     investments are reflected on a consolidated basis.
(b)  We own interests in 17 independent power projects located in seven states
     and Jamaica. Of these, 16 are currently in commercial operation. These
     investments are aggregated because individual investments are not
     significant.
(c)  In 1996, our Aquila Gas Pipeline (AQP) subsidiary acquired an equity
     interest in a pipeline for $132.0 million. In 1997, AQP sold 5% of its

NOTE 7:

NEW ZEALAND AND AUSTRALIA TRANSACTIONS

INTEREST IN NEW ZEALAND ELECTRIC UTILITIES

Through a series of transactions in 1998, we acquired an additional 48% of Power
New Zealand's common stock for approximately $245 million, increasing our
ownership to 78.6%. Concurrent with this acquisition, we sold our 39.6% interest
in New Zealand's WEL Energy Group, which we acquired throughout 1995, 1996 and
1997, and bought out the 21% minority shareholder in our New Zealand subsidiary,
UtiliCorp N.Z., Inc.

     New Zealand's Electricity Industry Reform Act of 1998 requires all the
country's utilities to separate ownership of their lines (network) and supply
(generation and retail) businesses. Power New Zealand, with approximately 90% of
its assets and earnings in the lines area, on November 13 announced its
intention to remain in the network business and to exit the supply business. It
also agreed to purchase the Wellington-based lines assets of TransAlta New
Zealand Ltd. and to sell to TransAlta its retail electricity business serving
the Auckland area for a net expenditure by Power New Zealand of $238 million.

     Because Power New Zealand's name transferred to TransAlta as part of the
retail business TransAlta acquired, the network business became UnitedNetworks
Limited on January 1, 1999.

                                                                              49

<PAGE>

    On November 20, Power New Zealand agreed to purchase the electric line 
assets of neighboring power company TrustPower Limited for approximately $261 
million. The assets became part of a greater network which includes parts of 
metropolitan Auckland and other areas in the central and southern regions of 
New Zealand's North Island. The TrustPower transaction closed in January 
1999. Completion of the TransAlta and TrustPower transactions created the 
country's largest electricity distribution network, serving about 468,000 
customers.

INITIAL PUBLIC OFFERING--UNITED ENERGY LIMITED

In May 1998, United Energy Limited (UEL) sold 42% of its common stock to the 
Australian public and as a result, we recorded a $45.3 million gain. The 
partial sale to the public reduced our effective ownership percentage to 29%. 
Concurrent with UEL's stock offering, we bought an additional 5% in UEL from 
another company to bring our ownership in UEL to 34%. Prior to the common 
stock sale, UEL repaid approximately $101 million in debt notes owed to us. 
The management agreement between UEL and UtiliCorp remains in place.

NOTE 8: REGULATORY ASSETS

Our domestic utility operations are regulated by state or local authorities. 
Our financial statements therefore include the economic effects of rate 
regulation. This means our consolidated balance sheet shows some assets and 
liabilities that would not be found on the balance sheet of a non-regulated 
company. There is a risk that if the domestic utility industry deregulates, 
we may have to remove the effects of regulation from our financial statements.

    The following table lists the regulatory assets and liabilities recorded 
at December 31, 1998 and 1997. These are primarily shown as deferred charges 
and credits on the consolidated balance sheets.

    We have a $150 million commercial paper program supported by a $250 
million revolving credit agreement. The credit agreement allows us to issue 
commercial paper at a favorable interest rate. Our credit agreement contains 
restrictive covenants and charges an annual commitment fee of .17% on the 
unused portion.

    During 1998 we put in place two New Zealand credit facilities that we 
used to acquire additional shares in UnitedNetworks. These facilities have 
the following terms.

bonds.

RETIREMENT OF DEBT

In March 1997 we retired, at a premium, $69.1 million of our 10.5% series 
senior notes that were to mature in 2020. This transaction resulted in an 
extraordinary loss of $7.2 million, net of an income tax benefit of $4.5 
million. 

NEW ZEALAND DENOMINATED CREDIT FACILITIES

UtiliCorp South Pacific, Inc. (USP) has a $NZ135 million credit facility with 
a consortium of banks that was used to finance a portion of the investments 
made by UNZ. The interest rate fluctuates (4.36% at December 31, 1998) with 
changes in the New Zealand bank bill rate. The credit facility matures on 
June 30, 1999. A commitment fee of .20% applies to the unused portion of the 
credit facility. UnitedNetworks has a three-year term loan facility to 
finance the acquisitions of TransAlta's (December 1998) and TrustPower's 
(January 1999) lines businesses. The maximum amount of the facility is $NZ 1 
billion. The interest rate is fixed through series of swaps at 7.70%

AUSTRALIAN DENOMINATED CREDIT FACILITIES

We maintain a $A150 million credit facility with a bank that matures in July 
2000. The interest rate for $A100 million of this facility fluctuates with 
changes in the Australian bank bill rate. At December 31, 1998, $A100 million 
was outstanding under the floating rate portion of this facility at a rate of 
5.21%. The interest rate on the remaining $A50 million of this facility is 
fixed at 7.48%, with $A50 million outstanding at December 31, 1998. A 
commitment fee of .20% applies to the unused portion of the credit facility.
     We also have a $A100 million credit facility with a consortium of banks 
that matures in July 2000. The interest rate on this facility fluctuates with 
changes in the Australian bank bill rate. At December 31, 1998, $A15 million 
was outstanding at a rate of 5.33%. A commitment fee of .20% applies to the 
unused portion of the credit facility.


NOTE 11: COMPANY-OBLIGATED PREFERRED SECURITIES

In June 1995, UtiliCorp Capital L.P. (UC), a limited partnership of which we 
are the general partner, issued 4 million shares of 8.875% Cumulative Monthly 
Income Preferred Securities, Series A, for $100 million. The limited 
partnership interests represented by the preferred securities are redeemable 
at the option of UC, after June 12, 2000, at $25 per preferred security plus 
accrued interest and unpaid dividends.

Holders of the securities are entitled to receive dividends at an annual rate 
of 8.875% of the liquidation preference value of $25. Dividends are payable 
monthly and in substance are tax-deductible by the company. The securities are 
shown as company-obligated mandatorily redeemable preferred securities of 
partnership on the consolidated balance sheets. The dividends are shown as 
minority interest in income of partnership in the consolidated statements of 
income.

NOTE 12: CAPITAL STOCK

COMMON STOCK OFFERING

We have two types of authorized common stock--unclassified common stock and 
Class A common stock. No Class A common stock is issued or outstanding. As of 
December 31, 1998, we had no restrictions on our ability to pay cash 
dividends.

COMMON STOCK SPLIT

In November 1998, our Board of Directors approved a 3-for-2 common stock 
split. The stock split is effective March 12, 1999 and all share amounts, 
share prices and per share figures have been restated.

STOCKHOLDER RIGHTS PLAN

Our Board adopted a rights plan and declared a dividend distribution of one 
right for each outstanding common share. The rights are not currently 
exercisable. Each right, when exercisable, would entitle each right holder to 
purchase one one-thousandth of a share of Series A Participating cumulative 
Preference Stock at a price of $77. The rights become exercisable if a person 
has acquired 15% of the outstanding common stock. Once the rights become 
exercisable, each rights holder can purchase common stock in the company at a 
market value twice the exercise price of the right.

DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN

We offer to current and potential shareholders a Dividend Reinvestment and 
Common Stock Purchase Plan (the Stock Plan).

     The Stock Plan allows participants to purchase up to $10,000 per month 
of common stock at a five-day average market price, without sales 
commissions. The Stock Plan also allows members to reinvest dividends into 
additional common shares at a 5% discount.

     For the year ended December 31, 1998, 1,125,000 shares were issued under 
the Stock Plan. As of December 31, 1998, 6,206,537 shares were available to 
issue under this plan.

EMPLOYEE STOCK PURCHASE PLAN

Participants in our Employee Stock Purchase Plan have the opportunity to buy 
shares of common stock at a reduced price through regular payroll deductions 
and/or lump sum deposits of up to 20% of the employee's base salary.  
Contributions are credited to the participant's account throughout an option 
period. At the end of the option period, the participant's total account 
balance is applied to the purchase of common stock. The shares are purchased 
at 85% of the lower of the market price

52

<PAGE>

on the first day or the last day of the option period. Participants must be 
enrolled in the Plan as of the first day of an option period in order to 
participate in that option period.

RESTATED SAVINGS PLAN

A defined contribution plan, the Restated Savings Plan (Savings Plan), covers 
all of our full-time and eligible part-time employees. Participants may 
generally elect to contribute up to 15% of their annual pay on a before- or 
after-tax basis subject to certain limitations. The company generally matches 
contributions up to 6%. Participants may direct their contributions into five 
different investment options. All company matching contributions are in 
UtiliCorp common stock. The Savings Plan also includes a stock contribution 
fund to which the company can contribute an additional amount of company 
common stock for participants.

STOCK INCENTIVE PLAN

Our Stock Incentive Plan enables the company to grant common shares to 
certain employees as restricted stock awards and as stock options. Shares 
issued as restricted stock awards are held by the company until certain 
restrictions lapse, generally on the third award anniversary. The market 
value of the stock, when awarded, is amortized to compensation expense over 
the three-year period. Stock options granted under the Plan allow the 
purchase of common shares at a price not less than fair market value at the 
date of grant. Options are generally exercisable commencing with the first 
anniversary of the grant. They grant 10 years after the date of grant.

EMPLOYEE STOCK OPTION PLAN

The Board approved the establishment of an Employee Stock Option Plan in 
1991. This Plan provides for the granting of up to 1.5 million stock 
options to full-time employees other than those eligible to receive options 
under the Stock Incentive Plan. Stock options granted under the Employee 
Stock Option Plan carry the same provisions as those issued under the Stock 
Incentive Plan. During 1988 and 1992, respectively, options for 1,278,713 and 
1,114,350 shares were granted to employees. The exercise prices of these 
options are $24.02 and $18.21, respectively.

This table summarizes stock options as of December 31, 1998 and 1997:

    We had alternative minimum tax credit carryforwards of approximately 
$93.4 million at December 31, 1998. Alternative minimum tax credits can be 
carried forward indefinitely. The company has not recorded a valuation 
allowance against its tax credit carryforwards.

    We have made no provision for U.S. income taxes on undistributed earnings 
from our international businesses ($145.0 million at December 31, 1998) 
because it is our intention to reinvest those earnings. If we distribute 
those earnings in the form of dividends, we may be subject to both foreign 
withholding taxes and U.S. income taxes net of allowable foreign tax credits. 
Consolidated income before income taxes for the years ended December 31, 
1998, 1997 and 1996 included (in millions) $70.5, $13.6 AND $39.2, 
respectively, from international operations.

     The U.S. pension plan was amended effective October 1, 1998 to provide 
the same pension benefits for almost all participants. In one location, we 
recorded pension expense using a modified amortization of gains and losses 
consistent with the rate treatment allowed for this cost.

     Our health care plans are contributory, with participants' contributions 
adjusted annually. The life insurance plans are non-contributory. We have 
assumed in estimating future health care costs future cost-sharing changes. 
The expense recognition for health care costs does not necessarily match the 
cost estimates due to certain differences in regulatory accounting at 
domestic utility operations.

     The assumed health care cost trends significantly affect the amounts 
reported for the health care plans. A one-percentage-point change in assumed 
health care cost trend rates would have the following effects for Fiscal Year 
1998.

contributions were $8.4 million and $8.1 million during the plan years ending 
December 1998 and 1997, respectively.

<PAGE>

    Future minimum lease payments primarily relate to our interest in the 
Jeffrey Energy Center, peaking turbines, coal cars and office space. Rent 
expense for the years 1998, 1997 and 1996 was (in millions) $31.1, $32.1 and 
$29.4, respectively.

    A 1998 court ruling required United Gas to pay the gas cost amount in 
accordance with a contract that was subject to a legal dispute. In addition, 
United Gas is required to pay interest to the supplier on the $38 million. We 
estimate this will cost $6.8 million.

    In 1998 we entered into a 15-year agreement to obtain the rights to 
dispatch 267 megawatts of power from facilities currently being built by a 
third party. As part of the agreement we will provide the natural gas to the 
power plant and will be able to dispatch the power. The plant is expected to 
be available in June 2000.

ENVIRONMENTAL

We are subject to various environmental laws. These include regulations 
governing air and water quality and the storage and disposal of hazardous or 
toxic wastes. We continually assess ways to ensure we comply with laws and 
regulations on hazardous materials and hazardous waste and remediation 
activities. 

    We own or previously operated 29 former manufactured gas plants (MGPs) 
which may, or may not, require some form of environmental remediation. We 
have contacted appropriate federal and state agencies and are working to 
determine what, if any, specific cleanup activities these sites may require.

    As of December 31, 1998, we estimate cleanup costs on our identified MGP 
sites to be $10.0 million. This estimate could change materially when we have 
investigated further. It could also be affected by the actions of 
environmental agencies and the financial viability of other responsible 
parties. Ultimate liability also may be affected significantly if we are held 
responsible for parties unable to contribute financially to the cleanup 
effort.

    We have received favorable rate orders that enable us to recover 
environmental cleanup costs in certain jurisdictions. In other jurisdictions, 
there are favorable regulatory precedents for recovery of these costs. We 
are also pursuing recovery from insurance carriers and other potentially 
responsible parties.

    In December 1996, the U.S. Environmental Protection Agency (EPA) 
published its final rule for nitrous oxide (NOx) emissions as required by 
the Clean Air Act Amendments of 1990. The new NOx regulations require that we 
install additional emissions control equipment at one of our power plants by 
January 1, 2000.

    In October 1998, the EPA published new air quality standards to further 
reduce the emission of NOx. These more strict standards will require us to 
install new equipment on our baseload coal units in Missouri that we 
estimate will cost $35 million. The ultimate cost is under debate and subject 
to change. The new standards as written are effective in May 2003.

    We do not expect final resolution of these environmental matters to have a  
a material adverse affect on our financial position or results of operations.

RATE PROCEEDING

We filed and have pending a request to increase our gas and electric rates in 
West Virginia by $4.7 million and $2.9 million, respectively. We expect final 
rates in late 1999.

OTHER

The company is subject to various legal proceedings and claims that arise in 
the ordinary course of business operations. We do not expect the amount of 
liability, if any, from these actions to materially affect our consolidated 
financial position or results of operations.

NOTE 17: MERGERS

ST. JOSEPH LIGHT & POWER COMPANY 
(UNAUDITED)

On March 4, 1999, we agreed to merge with St. Joseph Light & Power Company 
(SJL&P). Under the agreement, SJL&P shareholders will receive a fixed $23.00 
per share for each SJL&P common share. This will be converted into UtiliCorp 
common shares when the merger is completed. We expect to account for the 
transaction as a pooling of interests, although that is not a condition of 
the agreement. The merger is subject to approval by SJL&P shareholders and 
state and federal regulatory agencies and is expected to close in mid-2000.

KANSAS CITY POWER & LIGHT COMPANY (KCPL)

In September 1996, KCPL terminated the Amended and Restated Agreement and 
Plan of Merger (the Agreement) among KCPL, KC Merger Sub, Inc., UtiliCorp 
United Inc. and KC United Corp., which would have provided for the merger of 
UtiliCorp and KCPL.

    Since KCPL's shareholders did not approve the merger under the terms of 
the Agreement, KCPL was required to pay us $5.0 million. We received this 
payment in September 1996. In connection with the Agreement termination, we 
expensed deferred merger costs of about $11.0 million (pretax), net of the 
termination fee payment.

    In February 1997, Western Resources Inc. and KCPL signed a definitive 
agreement to merge. As a result, KCPL paid us a $53.0 million breakup fee. 
We recorded this merger termination fee in the first quarter of 1997.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF UTILICORP UNITED INC.:

We have audited the accompanying consolidated balance sheets of UtiliCorp 
United Inc. and subsidiaries at December 31, 1998 and 1997 and the related 
consolidated statements of income, common shareowners' equity, comprehensive 
income, and cash flows for each of the three years in the period ended 
December 31, 1998. These financial statements are the responsibility of the 
company's management. Our responsibility is to express an opinion on these 
financial statements based on our audits.

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

     In our opinion, the financial statements referred to above present 
fairly, in all material respects, the consolidated financial position of 
UtiliCorp United Inc. and subsidiaries at December 31, 1998 and 1997 and the 
consolidated results of their operations and their cash flows for each of the 
three years in the period ended December 31, 1998 in conformity with 
generally accepted accounting principles.

     As explained in Note 4 to the consolidated financial statements, 
effective October 1 , 1997, the company changed its method of accounting for 
internally developed software costs.
