ITEM 1.  BUSINESS

                                     GENERAL

PACCAR FINANCIAL CORP.

     PACCAR Financial Corp. (the "Company"), a wholly-owned subsidiary of PACCAR
Inc ("PACCAR") is a Washington corporation organized in 1961 to finance the sale
of PACCAR products. The Company provides financing and leasing of trucks and
related equipment manufactured primarily by PACCAR and sold through PACCAR's
independent dealers in the United States. The Company also finances dealer
inventories of transportation equipment.

PACCAR

     PACCAR is a multi-national company whose principal products are commercial
trucks and related service parts. This business accounted for 93% of PACCAR's
total revenues in 1999. PACCAR markets trucks in the heavy-duty diesel category
under the Kenworth, Peterbilt, DAF, and Foden nameplates primarily through its
dealers. These vehicles are manufactured in five plants in the U.S., three in
Europe and one each in Canada, Australia and Mexico. PACCAR also competes in the
North American Class 6/7 markets. These medium-duty trucks are assembled at
PACCAR's recently renovated Quebec plant and at a PACCAR factory in Mexico. This
line of business represents a small, but growing, percentage of PACCAR's North
American sales. PACCAR competes in the European medium commercial vehicle market
with a cab-over-engine truck manufactured in the Netherlands. Leyland
manufactures light commercial vehicles in the United Kingdom for sale throughout
Europe under the DAF and Leyland DAF nameplates. PACCAR competes in the truck
parts aftermarket primarily through its independent dealer networks. Other
PACCAR businesses include industrial winches. PACCAR sold its automotive parts
retail subsidiary during the fourth quarter of 1999.

     In the United States, Kenworth and Peterbilt trucks are sold to an
independent dealer network for resale to retail purchasers. Trucks manufactured
in the United States for export are marketed by a division of PACCAR through an
independent international dealer network.

     In addition to the Company, which provides financing and leasing in the
United States, PACCAR offers similar financing programs for PACCAR products in
Mexico, Canada, Australia and the United Kingdom through five other wholly owned
finance companies. PACCAR also provides full service truck leasing through a
wholly owned subsidiary.

     As of December 31, 1999, PACCAR and its subsidiaries had total assets of
$7.9 billion and stockholders' equity of $2.1 billion. For the year ended
December 31, 1999, PACCAR's consolidated revenues and net income were $9.0
billion and $583.6 million respectively.

     There were four other principal competitors besides PACCAR in the U.S.
Class 8 truck market in 1999. Based on 1999 industry registration statistics,
PACCAR's Kenworth and Peterbilt combined truck sales accounted for approximately
21% of domestic Class 8 new truck registrations. There were seven other
principal competitors in the European medium and heavy commercial vehicle market
in 1999 including parent companies of three competitors of PACCAR in the United
States. PACCAR's subsidiary, DAF, had a 10% share of the western European
heavy-duty market. These markets are highly competitive in price, quality and
service. PACCAR is not dependent on any single customer for a significant amount
of its sales.

                                      -2-

     PACCAR's common stock, $1 par value, is traded on the NASDAQ National
Market under the symbol "PCAR". PACCAR and the Company are subject to the
informational requirements of the Securities Exchange Act of 1934 and in
accordance therewith file reports and other information with the Securities and
Exchange Commission (the "Commission"). All reports, proxy statements and other
information filed by PACCAR and the Company with the Commission may be inspected
and copied at the public reference facilities maintained by the Commission at

                             BUSINESS OF THE COMPANY

     The Company operates primarily in one industry segment, truck and related
equipment financing. The Company provides financing for dealers' sales of
Kenworth and Peterbilt trucks in the United States. In addition, the Company
provides financing for dealers' purchases of new Class 6, 7 and 8 trucks and
used trucks, regardless of make or model. Financing is also provided for truck
trailers and allied equipment such as mixer and dump bodies attached to trucks.

     The Company currently conducts business with most PACCAR dealers. The
volume of the Company's business is significantly affected by PACCAR's sales and
competition from other financing sources.

     As of December 31, 1999, the Company employed 280 full-time employees, none
of whom are represented by a collective bargaining agent. The Company considers
relations with its employees to be good.

THE COMPANY'S PRODUCTS

RETAIL RECEIVABLES

     RETAIL CONTRACTS The Company purchases contracts from dealers and receives
assignments of the contracts and a first lien security interest in the vehicles
financed ("Retail Contracts"). Collateral for vehicles sold to leasing companies
may also include an assignment of leases and rentals due. Retail Contracts
purchased by the Company have fixed or floating interest rates.

     DIRECT LOANS The Company also makes loans to the end users of the vehicles
financed that are secured by a first lien security interest in the vehicles
("Direct Loans"). Direct Loans have fixed or floating interest rates.

MASTER NOTE

     These contracts are an alternative form of retail financing offered to
select dealers for new and used trucks. Retail installment contracts originated
by the dealer for new or used trucks and meeting the Company's requirements as
to form, terms and creditworthiness for Retail Contracts are pledged to the
Company as collateral for direct, full recourse loans by the Company to the
dealer ("Master Note"). Master Note contracts have fixed or floating interest
rates.

WHOLESALE CONTRACTS

     The Company provides wholesale financing for new and used truck and trailer
inventories for dealers ("Wholesale Contracts"). Wholesale Contracts are secured
by the inventories financed. The amount of credit extended by the Company for
each truck is generally limited to the invoice price of new equipment and to the
wholesale value of used equipment. Interest under Wholesale Contracts is based
upon floating rates.

                                      -3-

<PAGE>

DEALER LOANS

     The Company makes loans to selected Peterbilt and Kenworth dealers ("Dealer
Loans"). The purposes of these loans include the financing of real estate, fixed
asset, working capital and dealership acquisitions. Dealer loans may have fixed
or floating interest rates.

LEASES

     The Company offers lease contracts where it is treated as the owner of the
equipment for tax purposes and generally retains the tax depreciation
("Leases"). The lessee is responsible for the payment of property and sales
taxes, licenses, maintenance and other operating items. The lessee is obligated
to maintain the equipment and to insure the equipment against casualty and
liability losses.

     Most of the Company's Leases contain a Terminal Rental Adjustment Clause,
which requires the lessee to guarantee to the Company a stated residual value
upon disposition of the equipment at the end of the lease term.

INSURANCE

     The Company sells physical damage insurance through PACCAR dealers who are
licensed insurance agents as well as through licensed agents of the Company. The
Company retains the premium revenues and loss exposure for the policies, which
are issued through an unrelated insurance carrier.

     The Company also charges a fee to provide insurance coverage, through an
unrelated regulated insurance carrier, on new trucks, used trucks and trailer
inventory to dealers having Wholesale Contracts with the Company. The Company
retains annual loss exposure up to that year's fee revenues.

          CUSTOMER CONCENTRATION, PAST DUE ACCOUNTS AND LOSS EXPERIENCE

CUSTOMER CONCENTRATION

     At December 31, 1999, the largest single customer for Retail Contracts,
Direct Loans or Leases represented 1.1% of the Company's receivables, and the
five largest such accounts amounted to 4.2% of receivables.

     At December 31, 1999, the Company had four Master Note dealers. Master Note
borrowings totaled 10.7% of the Company's receivables, while the largest Master
Note dealer's borrowing amounted to 8.6% of the Company's receivables. Master
Note receivables are secured by numerous retail installment contracts, which, in
effect, reduces the amount of dealer concentration.

     With respect to wholesale financing, at December 31, 1999, the largest
single dealer group accounted for 2.3% of the Company's receivables, and the
five largest dealer groups collectively accounted for 5.6% of receivables.

PAST DUE RECEIVABLES AND ALLOWANCE FOR LOSSES

     An account is considered past due by the Company if any portion of an
installment is due and unpaid for more than 30 days. In periods of adverse
economic conditions, past due levels, repossessions and credit losses generally
increase.

                                      -4-

<PAGE>

   The Company maintains an allowance for losses on receivables at a level,
which it considers to be adequate to cover management's estimates of losses. The
following table summarizes the activity in the Company's allowance for losses on
receivables and presents related ratios:

                        COMPETITION AND ECONOMIC FACTORS

     The truck financing business is highly competitive among banks, commercial
finance companies, captive finance companies and leasing companies. Many of
these institutions have substantially greater financial resources than the
Company and may borrow funds at lower rates.

     The dealers are the primary source of contracts acquired by the Company.
However, dealers are not required to obtain financing from the Company, and they
have a variety of other sources, which may be used for wholesale and customer
financing of trucks. Retail purchasers also have a variety of sources available
to finance truck purchases.

     The ability of the Company to compete in its market is principally based on
the rates and terms which the Company offers dealers and retail purchasers, as
well as the specialized services it provides. Rates and terms are based on the
Company's desire to provide flexible financing which meets dealer and customer
financing needs, the ability of the Company to borrow funds at competitive rates
and the Company's need to earn an adequate return on its invested capital. The
Company's business is also affected by changes in market interest rates, which
in turn are related to general economic conditions, demand for credit, inflation
and governmental policies. Seasonality is not a significant factor in the
Company's business.

                                      -5-

<PAGE>

     The volume of receivables available to be acquired by the Company from
dealers is largely dependent upon the number of Kenworth and Peterbilt trucks
sold. Domestic sales of heavy-duty trucks depend on the capital equipment
requirements of the transportation industry, which in turn are influenced by
economic growth and cyclical variations in the economy. Heavy-duty truck sales
are also sensitive to economic factors such as fuel costs, interest rates,
federal excise and highway use taxes and taxation of the acquisition and use of
capital goods.

                         REGULATIONS AND SIMILAR MATTERS

     In certain states, the Company is subject to retail installment sales or
installment loan statutes and related regulations, the terms of which vary from
state to state. These laws may require the Company to be licensed as a sales
finance company and may regulate disclosure of finance charges and other terms
of retail installment contracts. The Company is also subject to some of the
provisions of federal law relating to discrimination in the granting of credit.

                                SOURCES OF FUNDS

     The operations of the Company are financed by borrowings, retained earnings
and PACCAR equity investments. The Company's profitable acquisition of
additional receivables is dependent upon its ability to raise funds at
competitive rates in the public and private debt markets. The receivables and
leases that are financed are either fixed rate or floating rate, terms of
generally five years or less.

     To reduce the risk of changes in interest rates that could affect interest
margins, the Company obtains funds with interest rate characteristics similar to
the corresponding assets. Fixed rate assets are funded primarily with publicly
offered fixed rate medium-term notes and commercial paper combined with interest
rate swaps. Floating rate assets are funded primarily with commercial paper with
maturities of three months or less. As a result, the Company's interest margin
on existing business does not change significantly as interest rates change.

     The Company enters into interest rate contracts as a tool to achieve its
matched funding objectives and to reduce total borrowing costs relative to its
primary borrowing sources--commercial paper and fixed rate medium-term notes.
Fixed interest rate swaps, matched to floating rate borrowings, are used to lock
in the funding cost of fixed rate assets. Floating interest rate swaps, matched
to either fixed or floating rate debt, are used to convert to a floating rate
index more appropriate to the Company's floating rate assets. Interest rate caps
are occasionally purchased to hedge the floating rate funding cost of floating
rate assets that have a maximum yield. As of December 31, 1999, the total
notional principal amount of interest rate swap contracts outstanding was $1,058
million, all of which result in a fixed rate payment obligation. The notional
amount is used to measure the volume of these contracts and does not represent
exposure to credit loss. The Company's risk in these transactions is the cost of
replacing, at current market rates, these contracts in the event of default by
the counterparty. Management believes the risk of incurring such losses is
remote, and any losses would be immaterial. The permitted types of interest rate
contracts, their transaction limits and related approval authorizations have
been established by the Company's senior management and Board of Directors. The
interest rate contracts outstanding are regularly reported to, and reviewed by,
the Company's senior management.

     As of December 31, 1999, the Company had $815 million of unused, confirmed
bank lines of credit, $760 million of which are shared with PACCAR, that are
reviewed annually for renewal. These lines are maintained primarily to support
the Company's short-term borrowings. Neither PACCAR nor the Company is liable
for any borrowings of the other under these lines of credit.

                                      -6-

<PAGE>

     As of December 31, 1999, the Company had $1,198 million of medium-term
notes outstanding, $523 million of which was due within 12 months. See "Note
E--Borrowings" in the Notes to Financial Statements for medium-term note
maturities.

     An indenture of the Company dated as of December 1, 1983, as amended by a
first supplemental indenture dated June 19, 1989 (Exhibit 4.1), with respect to
the Company's medium-term notes which are publicly issued from time to time,
contains restrictions limiting secured debt which may be incurred by the Company
and any subsidiary.

                            RELATIONSHIP WITH PACCAR

GENERAL

     The operations of the Company are fundamentally affected by its
relationship with PACCAR. Sales of PACCAR products are the Company's principal
source of financing business. The Company receives administrative support from
and pays dividends to PACCAR, and may occasionally borrow funds from or lend
money to PACCAR or it's affiliates. Since the directors of the Company are all
executives of PACCAR or its affiliated companies and PACCAR is the sole owner of
the Company's outstanding voting common stock, PACCAR can determine the course
of the Company's business. See "Note D--Transactions with PACCAR and Affiliates"
in the Notes to Financial Statements.

SUPPORT AGREEMENT

     The Company and PACCAR are parties to a Support Agreement which obligates
PACCAR to provide, when required, financial assistance to the Company to assure
that the Company maintains a ratio of net earnings available for fixed charges
to fixed charges (as defined) of at least 1.25 to 1 for any fiscal year. The
Support Agreement also requires PACCAR to own, directly or indirectly, all
outstanding voting stock of the Company. The required ratio for each of the
years ended December 31, 1995 - 1999 was met without assistance.

     The Company and PACCAR may amend or terminate any or all of the provisions
of the Support Agreement upon 30 days notice, with copies of the notice being
sent to all nationally recognized statistical rating organizations ("NRSROs")
which have issued ratings with respect to debt of the Company ("Rated Debt").
Such amendment or termination will be effective only if (i) two NRSROs confirm
in writing that their ratings with respect to any Rated Debt would remain the
same after such amendment or termination, or (ii) the notice of amendment or
termination provides that the Support Agreement will continue in effect with
respect to Rated Debt outstanding on the effective date of such amendment or
termination unless such debt has been paid or defeased pursuant to the indenture
or other agreement applicable to such debt, or (iii) the holders of at least
two-thirds of the aggregate principal amount of all outstanding Rated Debt with
an original maturity in excess of 270 days consent in writing to such amendment
or termination, provided that the holders of Rated Debt having an original
maturity of 270 days or less shall continue to have the benefit of the Support
Agreement until the maturity of such debt.

     The Support Agreement expressly states that PACCAR's commitments to the
Company thereunder do not constitute a PACCAR guarantee of payment of any
indebtedness or liability of the Company to others and do not create rights
against PACCAR in favor of persons other than the Company. There are no
guarantees, direct or indirect, by PACCAR of payment of any indebtedness of the
Company.

ITEM 2.  PROPERTIES

     The Company's principal office is located in the corporate headquarters
building of PACCAR (owned by PACCAR) at 777 - 106th Avenue N.E., Bellevue,
Washington 98004.

     Other offices of the Company are located in leased premises. Annual lease
rentals for offices in the aggregate are not material in relation to expenses as
a whole.

ITEM 3. LEGAL PROCEEDINGS

     The Company is a party to various routine legal proceedings incidental to
its business involving the collection of accounts and other matters. The Company
does not consider such matters to be material with respect to the business or
financial condition of the Company as a whole.

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

     Not applicable.

                                     PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

     All outstanding common stock is owned by PACCAR; therefore, there is no
trading market in the Company's common stock.

     The Company began in 1994 to pay a dividend to PACCAR for the additional
paid-in capital invested in the prior year. Cash dividends of $2.3 million, $2.1
million and $2.7 million were paid in 1999, 1998 and 1997, respectively.

(1)     For purposes of this ratio, earnings consist of income before income
        taxes plus fixed charges. Fixed charges consist of interest expense plus
        a portion of rent expense (which is deemed representative of an interest
        factor). The method of computing the ratio of earnings to fixed charges
        shown above complies with SEC reporting requirements but differs from
        the method called for in the Support Agreement between the Company and
        PACCAR. The ratios computed pursuant to the Support Agreement were
        1.44x, 1.41x, 1.57x, 1.62x and 1.63x for the years 1999 - 1995,
        respectively. See Exhibits 12.1 and 12.2.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS, 1997 - 1999

RESULTS OF OPERATIONS
1999 Compared to 1998:
     1999 new business volume was $1.8 billion, increasing 20% over 1998's
record volume of $1.5 billion. As a result, average receivables grew 21% to $2.9
billion from $2.4 billion in 1998. The finance margin of $94.5 million for 1999
increased 11% from $85.0 million in 1998. However, the average margin rate on
receivables declined for the fifth consecutive year from 3.57% for 1998 to 3.23%
for 1999 due to higher leverage and intense rate competition in the truck
lending market. The insurance margin improved $.6 million due to higher premiums
and improved loss experience.

     Selling, general and administrative expenses of $27.4 million were 22%
lower in 1999 primarily because 1998's expenses included a $7.5 million one-time
charge-off of an investment in a new loan system. 1999 operating expenses were
favorably impacted in the amount of $1.4 million by a settlement with a vendor
related to the same project. Excluding the impact of these items, 1999 operating
expenses were 4% higher than in 1998 due primarily to higher salaries and
related costs and Year 2000 compliance efforts. The provision for losses
increased 36% to $15.6 million in 1999 from $11.5 million in 1998. This increase
is consistent with the Company's rapid asset growth. Credit losses increased to
$6.8 million in 1999 from $4.0 million in 1998 due partly to higher fuel prices
that have reduced operating margins for many truck operators. Management expects
this near-term trend to continue until fuel prices decline or operators
successfully pass those costs on to their customers. Despite recent trends, the
overall portfolio quality remains good. The level of the allowance for credit
losses reflects the risks inherent in the financing of commercial highway
transportation equipment.

     As a result of the foregoing factors, 1999 net income increased 35% to
$33.3 million from $24.6 million in 1998. Excluding the impact of the 1999
vendor settlement and the 1998 charge-off, net income for 1999 would have been
$32.4 million, representing an 11% increase from 1998 net income.

1998 Compared to 1997:
     Net income decreased 20% to $24.6 million in 1998 from $30.9 million in
1997. New business volume increased 31% to $1.5 billion from $1.2 billion in
1997. The provision for losses of $11.5 million in 1998 increased 84% compared
to 1997, despite lower credit losses, due to asset growth. Selling, general and
administrative expenses were 39% higher in 1998 than 1997 as a result of higher
staffing costs and the $7.5 million loan system investment charge-off.

FUNDING AND LIQUIDITY
     The Company manages its capital structure consistent with industry
standards. Since 1983, the Company has registered senior debt securities under
the Securities Act of 1933 for offering to the public. At the end of 1999, there
were $195 million of such securities available for issuance. The Company is in
the process of filing a new shelf registration statement, which is expected to
be completed by the end of the first quarter of 2000.

     The Company believes that it has sufficient financial capabilities,
including internally generated funds, access to public and private debt markets,
lines of credit and other financial resources, to fund current business needs
and service debt maturities.

     PACCAR made an additional $25 million investment in the Company through
paid-in capital in the third quarter of 1999.

YEAR 2000 ISSUE
The Company's total cost of identifying, evaluating, converting and testing its
major internal systems for Year 2000 compliance was $2.0 million and was funded
with operating funds. Management believes the Company's systems to be Year 2000
compliant and is not aware of the existence of any Year 2000 issues related to
its systems or the systems of its major vendors or the banks and financial
institutions with which it has relationships.

ITEM 7a. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISK AND DERIVATIVE FINANCIAL INSTRUMENTS
The Company's primary market risk exposure is to fluctuations in interest rates.
To manage the risks, the Company uses derivative financial instruments,
primarily interest rate swaps, in accordance with established policies and
procedures. The objectives are to reduce existing interest rate risk arising
from the financing of receivables, change interest rate characteristics of debt
to more closely reflect the interest rate characteristics of the receivables
being funded, and to reduce funding costs. Derivative usage is limited to
hedging strategies, which match the interest rate characteristics of debt to
those of the receivables being funded. The Company does not use derivatives for
trading purposes. Following is a tabular presentation of items, which are
subject to market risk exposure and the derivatives, which are used to manage
the exposure risk.

                Report of Ernst & Young LLP, Independent Auditors

Board of Directors
PACCAR Inc and PACCAR Financial Corp.

We have audited the accompanying balance sheets of PACCAR Financial Corp. (a
wholly-owned subsidiary of PACCAR Inc) as of December 31, 1999 and 1998, and the
related statements of income and retained earnings and cash flows for each of
the three years in the period ended December 31, 1999. 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 auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit 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 financial position of PACCAR Financial Corp. at
December 31, 1999 and 1998, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1999 in conformity
with accounting principles generally accepted in the United States.

NOTES TO FINANCIAL STATEMENTS
PACCAR Financial Corp.

December 31, 1999
(Thousands of Dollars)

NOTE A--SUMMARY OF ACCOUNTING POLICIES

INDUSTRY: PACCAR Financial Corp. (the "Company"), a wholly-owned subsidiary of
PACCAR Inc ("PACCAR"), provides financing of trucks and related equipment
manufactured primarily by PACCAR and sold by authorized dealers. The Company
also finances dealer inventories of transportation equipment. The operations of
the Company are fundamentally affected by its relationship with PACCAR. Sales of
PACCAR products are the Company's principal source of financing business.

Due to the nature of the Company's business, customers are concentrated in the
transportation industry throughout the United States. The Company's receivables
and direct financing lease portfolio are not concentrated in any geographic
region. Generally, all receivables are collateralized by the equipment being
financed. The risk of credit losses related to this concentration has been
considered in establishing the allowance for losses.

USE OF ESTIMATES: The preparation of financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates and assumptions that affect amounts reported and
disclosed in the financial statements. Actual results could differ from the
amounts estimated by management.

ESTIMATED LOSSES ON RECEIVABLES: The provision for losses on finance and other
receivables is charged to income in an amount sufficient to maintain the
allowance for losses at a level considered adequate to cover estimated losses.
Receivables are charged to this allowance when, in the judgment of management,
they are deemed uncollectible (usually upon repossession of the collateral). On
certain retail contracts acquired from the dealers, the dealer retains
liability, up to specified limits, for the credit loss on the sale of a
repossessed vehicle. The amount and collectibility of dealer recourse provisions
have been considered in establishing the allowance for losses on receivables.

REVENUE RECOGNITION: Revenue from finance receivables and other receivables is
recognized using the interest method. Certain loan origination costs are
deferred and amortized to interest and other income. For operating leases,
income is recognized on a straight-line basis over the lease term.

Recognition of income is suspended when management determines that collection of
future income is not probable (generally after 90 days past due). Recognition is
resumed if the receivable becomes contractually current and collection doubts
are removed.

EQUIPMENT: Equipment on operating leases is recorded at cost and depreciated on
a straight-line basis over the contract term of each operating lease to an
estimated residual value.

INCOME TAXES: The Company is included in the consolidated federal income tax
return of PACCAR. Income taxes for the Company are determined on a separate
return basis, and any related tax liability is paid by the Company to PACCAR and
any related tax benefit is paid by PACCAR to the Company.

(Thousands of Dollars)

DERIVATIVE FINANCIAL INSTRUMENTS: The Company enters into interest rate
contracts and cap agreements to manage certain exposures to fluctuations in
interest rates. The Company uses interest rate swap contracts to match the
interest rate characteristics of the Company's finance receivables with the
borrowings used to fund those receivables and to limit the Company's exposure to
rising interest rates. Interest rate swap contracts involve the exchange of
fixed and floating rate interest payments without the exchange of the underlying
principal. Net amounts paid or received are reflected as adjustments to interest
expense. Interest rate cap premiums paid are amortized to interest expense
ratably during the life of the agreement. The fair values of interest rate swap
and cap agreements are not recognized in the financial statements. Realized
gains or losses at the time of maturity, termination or repayment of an interest
rate contract or cap agreement are recorded in a manner consistent with the
original designation of the interest rate contract or cap agreement. The Company
does not engage in derivatives trading, market-making or other speculative
activities.

RECLASSIFICATIONS: Certain prior year amounts have been reclassified to conform
to the 1999 presentation.

NEW ACCOUNTING PRONOUNCEMENTS:
In June 1999, the Financial Accounting Standards Board issued Statement No. 137,
ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES-DEFERRAL OF THE
EFFECTIVE DATE OF FASB STATEMENT NO. 133--AN AMENDMENT OF FASB STATEMENT NO.
133. This pronouncement postponed the required adoption of FASB statement No.
133 from first quarter 2000 to first quarter 2001. Based on review of FASB
Statement No. 133, management believes its current use of derivatives for
hedging purposes will be considered cash flow hedges under the pronouncement.
Management does not anticipate that the adoption will have a significant effect
on earnings or the financial position of the Company. However, given the complex
nature of the new Standard and the dependence on market values, the impact will
not be known until adoption.

Terms of operating leases range up to 44 months. Future annual minimum rental
payments to be received for transportation equipment on operating leases
beginning January 1, 2000 were: $5,864 in 2000; $3,464 in 2001; $1,906 in 2002
and $218 in 2003.

NOTE D--TRANSACTIONS WITH PACCAR AND AFFILIATES

The Company and PACCAR are parties to a Support Agreement which obligates PACCAR
to provide, when required, financial assistance to the Company to assure that
the Company maintains a ratio of net earnings available for fixed charges to
fixed charges (as defined) of at least 1.25 to 1 for any fiscal year. The
Support Agreement also requires PACCAR to own, directly or indirectly, all
outstanding voting stock of the Company. The required ratio for the years ended
December 31, 1999, 1998 and 1997, was met without assistance.

PACCAR charges the Company for certain administrative services it provides.
These costs are charged to the Company based upon the Company's specific use
of the services and PACCAR's cost. Management considers these charges
reasonable and not significantly different from the costs that would be
incurred if the Company were on a stand-alone basis. Fees for services of
$1,772, $2,451 and $1,976 in 1999, 1998 and 1997, respectively, were charged
to the Company. In lieu of current year payment, PACCAR recognizes certain of
these administrative services as an additional investment in the Company. The
Company records the investment as paid-in capital. The Company pays a
dividend to PACCAR for the paid-in capital invested in the prior year. Cash
dividends of $2,284, $2,093, and $2,655 were paid in 1999, 1998 and 1997,
respectively. PACCAR made an additional $25 million investment in the Company
through paid-in capital in 1999.

The Company's employees are covered by a defined benefit pension plan, an
unfunded postretirement medical and life insurance plan and a defined
contribution plan sponsored by PACCAR. Separate allocations of plan assets,
defined benefit accumulated plan benefits and defined contribution plan
benefits relating to the Company have not been made. Expenses charged to the
Company by PACCAR for these plans were $1,238, $1,039, and $820 for years
1999, 1998 and 1997, respectively.

Periodically, the Company borrows funds from PACCAR and makes loans to PACCAR.
At December 31, 1999, 1998 and 1997, there were no outstanding loans for the
Company from or to PACCAR.

The Company periodically loans funds to certain foreign and domestic finance and
leasing affiliates of PACCAR. These various affiliates have Support Agreements
with PACCAR, similar to the Company's Support Agreement. The foreign affiliates
operate in the United Kingdom, Canada and Australia, and any resulting currency
exposure is fully hedged. The foreign finance affiliates provide financing and
leasing of trucks and related equipment manufactured primarily by PACCAR and
sold through PACCAR's independent dealer networks in the United Kingdom, Canada
and Australia. The domestic leasing affiliate finances trucks and trailers under
direct finance leases, operating leases and other financing agreements for terms
of one to ten years. The Company will not make loans to the foreign affiliates
in excess of the equivalent of $50 million United States dollars, or loans to
its domestic leasing affiliate in excess of $200 million, unless the amount in
excess of such limits is guaranteed by PACCAR. The Company periodically reviews
the funding alternatives for these affiliates, and these limits may be revised
in the future. There was a total of $24 million and $13 million in loans
outstanding to a foreign affiliate operating in the United Kingdom at December
31, 1999 and 1998, respectively, and no loans outstanding to other foreign or
the domestic affiliates for either period. There were no loans at December 31,
1997.

The Company's Articles of Incorporation provide that the 6% noncumulative,
nonvoting preferred stock (100% owned by PACCAR) is redeemable only at the
option of the Company's Board of Directors.

NOTES TO FINANCIAL STATEMENTS
PACCAR Financial Corp.
December 31, 1999
(Thousands of Dollars)

At December 31, 1999, the Company had outstanding 59 interest rate swaps with
various financial institutions with a total notional balance of $1,058 million.
The notional principal of these contracts matures as follows: $549 million in
2000, $307 million in 2001, $150 million in 2002, $44 million in 2003, and $8
million thereafter. The notional amount is used to measure the volume of these
contracts and does not represent exposure to credit loss. The Company's risk in
these transactions is the cost of replacing, at current market rates, these
contracts in the event of default by the counterparty. Management believes the
risk of incurring such losses is remote and any losses would be immaterial.

At December 31, 1999, the interest rate swap weighted average pay rate was
5.72%. The weighted average interest rate swap receive rate of 6.19% offsets the
pay rate on associated debt obligations.

NOTE F-- CREDIT ARRANGEMENTS

The Company and PACCAR have lines of credit arrangements with various commercial
banks that are reviewed annually for renewal. These lines are maintained
primarily to support the Company's short-term borrowings. At December 31, 1999,
the unused portion of these credit lines was $815 million of which $760 million
are shared with PACCAR. The Company compensates the banks for providing lines of
credit with fees that are immaterial.

The Company has entered into facility agreements with various lending
institutions, under which the lending institutions may sell a participation or
assign all or a portion of the note to other institutions. These notes generally
mature within 90 days. There were no notes outstanding at December 31, 1999 or
December 31, 1998.

NOTE H--FAIR VALUES OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used by the Company in estimating its
fair value disclosures for financial instruments:

CASH: The carrying amount reported in the balance sheets is stated at fair
value.

NET RECEIVABLES: For floating rate loans and wholesale financings, fair values
are stated at carrying values. For fixed rate loans, fair values are estimated
using discounted cash flow analyses applying interest rates currently being
offered for loans with similar terms to borrowers of similar credit quality. The
carrying amount of accrued interest and other receivables approximates their
fair value. Direct financing leases and the related allowance for losses are not
included in net receivables for purposes of fair value disclosures herein.

OFF-BALANCE-SHEET INSTRUMENTS: Fair values for the Company's interest rate
contracts are based on costs which would be incurred to terminate existing
agreements and enter into new agreements with similar notional amounts, maturity
dates and counterparties' credit standings at current market interest rates or
currency exchange rates.

COMMERCIAL PAPER, SHORT-TERM BANK LOANS AND MEDIUM-TERM NOTES: The carrying
amounts of the Company's commercial paper, bank loans and floating rate
medium-term notes approximate their fair value. The fair value of the Company's
fixed rate medium-term notes is estimated using discounted cash flow analyses,
based on the Company's current incremental borrowing rates for similar types of
borrowing arrangements.

The carrying amounts of trade payables and receivables approximate their fair
value and have been excluded from the accompanying table.

The carrying amounts and fair values of the Company's financial instruments are
as follows:

The Company's intent is to hold interest rate contracts until maturity. If
recorded at fair value at December 31, 1999, the Company's off-balance-sheet
financial instruments (interest rate contracts) would represent gross assets of
$11,341 and offsetting gross liabilities of $0, resulting in a net asset of
$11,341. If recorded at fair value at December 31, 1998, the Company's
off-balance-sheet financial instruments would have reflected a net liability of
$4,562.
