                         Report of Independent Auditors

Investment Committee and Plan Administrator
Arkansas Best 401(k) Savings Plan

We have audited the accompanying statements of net assets available for benefits
of the Arkansas Best 401(k) Savings Plan as of December 31, 2001 and 2000, and
the related statement of changes in net assets available for benefits for the
year ended December 31, 2001. These financial statements are the responsibility
of the Plan'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 net assets available for benefits of the Plan at
December 31, 2001 and 2000, and the changes in its net assets available for
benefits for the year ended December 31, 2001, in conformity with accounting
principles generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
(held at end of year) as of December 31, 2001, is presented for purposes of
additional analysis and is not a required part of the financial statements but
is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. The supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, is fairly stated in all material respects in relation to the financial
statements taken as a whole.

1. DESCRIPTION OF PLAN

The following brief description of the Arkansas Best 401(k) Savings Plan (the
Plan) provides only general information. Participants should refer to the Plan
document for a more complete description of the Plan's provisions.

GENERAL

The Plan is a defined contribution retirement savings plan which covers eligible
employees of Arkansas Best Corporation, and certain of its subsidiaries: ABF
Freight System, Inc., ABF Cartage, Inc., Data-Tronics Corp., FleetNet America,
LLC, Land-Marine Cargo, Inc., G.I. Trucking Company, and Best Service Corp.
(collectively the Company). Effective September 1, 2001, G. I. Trucking Company
(G.I.) ceased to be a participating company in the Plan and the G.I.
participants became fully vested in their accounts. On November 14, 2001,
investments totaling approximately $16.7 million were transferred to a successor
plan, representing the fair value of the individual accounts of G.I.
participants at the date of the transfer.

The Plan covers substantially all regular full-time employees of the Company,
except for employees of a collective bargaining unit, casual employees (defined
as part-time employees who work less than thirty hours per week) who have not
completed certain levels of service, and leased employees. The Plan is subject
to the provisions of the Employee Retirement Income Security Act of 1974
(ERISA).

CONTRIBUTIONS

Each year, participants may contribute a percentage of pre-tax compensation as
defined in the Plan document. Effective January 1, 1999, the Plan was amended to
allow for an automatic 3% pre-tax contribution by participants who do not elect
in writing to not have contributions made to the Plan. Certain participating
companies provide matching contributions to encourage participation in the Plan.
In addition to the matching contributions, each participating company may make
an additional annual contribution at the discretion of each participating
company's Board of Directors. For the year ended December 31, 2001, no
additional contributions were made.


                                                                               4

1. DESCRIPTION OF PLAN (CONTINUED)

For the year ended December 31, 2001, the Plan allowed participant and Company
matching contributions as outlined in the following table:

</Table>

PARTICIPANT ACCOUNTS

Each participant's account is credited with the participant's contribution and
allocations of (a) the matching contributions and any discretionary
contributions and (b) Plan earnings and is charged with benefit payments and
administrative expenses. Allocations are based on participant earnings or
account balances, as defined in the Plan document. The benefit to which a
participant is entitled is the benefit that can be provided from the
participant's vested account balance.

VESTING

Participants are immediately vested in their contributions plus earnings
thereon. The value of the matching contributions and earnings becomes 100%
vested after five years of service with the Company, or upon total or permanent
disability, or upon the death of the participant. Forfeitures of non-vested
amounts are used to reduce the future matching contributions.


                                                                               5

1. DESCRIPTION OF PLAN (CONTINUED)

PARTICIPANT NOTES RECEIVABLE

Participants may borrow from their accounts, subject to a minimum of $1,000 and
a maximum calculated as the lesser of: (a) 50% of the participant's vested
account balance or (b) $50,000 reduced by the participant's highest loan balance
in the preceding twelve-month period. Loan terms generally range from one to
five years; however, if the loan is for the purchase of a primary residence, the
repayment period may range from one to ten years.

Each loan is secured by 50% of the balance in the participant's account and
bears interest at a rate commensurate with local prevailing rates. Interest
rates range from 8% to 11%. Repayment is made through payroll deductions.

PAYMENT OF BENEFITS

Upon termination of service, a participant or the designated beneficiary will
receive a lump-sum amount equal to the value of the participant's vested account
balance at the date of termination.

ADMINISTRATIVE EXPENSES

All investment-related administrative charges are paid by the Plan as provided
in the Plan document. All audit, legal, and consulting fees incurred by the Plan
are paid by the Company.

PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the right
under the Plan to amend or terminate the Plan and the Trust at any time, by
action of the Board of Directors and subject to the provisions of ERISA. The
accounts of all participants affected by a termination will become
nonforfeitable as of the date of termination. In the event of Plan termination,
all participants will become 100% vested in their accounts.


                                                                               6

2. SUMMARY OF ACCOUNTING POLICIES

BASIS OF PRESENTATION

The accompanying financial statements have been prepared on the accrual basis of
accounting.

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
that affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates.

INVESTMENT VALUATION AND INCOME RECOGNITION

Common stocks are valued at the closing market price of the principal market on
which the stock is traded. Mutual fund shares are valued based on published
market prices, which represent the net asset values of shares held by the Plan
at year-end. The participant notes receivable are valued at cost, which
approximates fair value.

Purchases and sales of investments are recorded on a trade-date basis. Interest
and dividends are recorded on the accrual basis.

3. INVESTMENTS

The Plan's investments are held in the Arkansas Best Corporation and Affiliates
Employees' Investment Trust No. 1 (the Trust). The trustee for the Plan's
investments is Fidelity Management Trust Company (Fidelity).


                                                                               7

4. LIFE INSURANCE POLICIES

Insurance policies that were purchased under a prior option of the Plan continue
to exist; however, new investments in individual or group policies are not
allowed. Plan participants as of July 1, 1987, who invested in the insurance
option, continue to pay premiums and receive benefits in accordance with the
previously existing provisions of the Plan.

The Plan does not record any assets or liabilities in connection with the
previous life insurance option. The Plan purchases individual life insurance
contracts on behalf of the participants when contributions are made, with the
participant's account as beneficiary. The Plan itself has no liability to pay
any death benefits, because the insurance company assumes this liability upon
issuance of the policies.

Upon the death of the insured, the death benefits received by the Plan from the
insurance company are credited to the participant's account. The Plan cannot
purchase or terminate life insurance for a participant without that
participant's consent. Any cash surrender value received by the Plan upon
termination of a life insurance policy is credited to the participant's account.

5. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated July 26, 1999, stating that the Plan is qualified under Section 401(a) of
the Internal Revenue Code (the Code) and, therefore, the related Trust is exempt
from taxation. Once qualified, the Plan is required to operate in conformity
with the Code to maintain its qualification. The Plan has been amended since
receiving the determination letter; however, the Administrative Committee
believes the Plan is being operated in compliance with the applicable
requirements of the Code and, therefore, believes that the Plan is qualified and
the related Trust is tax-exempt.
