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


To the Retirement Committee of the
 Hartco Flooring Company
 Retirement Savings Plan:



We have audited the accompanying statements of net assets available for benefits
of the Hartco Flooring Company Retirement Savings Plan as of December 31, 2000
and 1999, and the related statements of changes in net assets available for
benefits for the years then ended.  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 of America.  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 Hartco
Flooring Company Retirement Savings Plan as of December 31, 2000 and 1999, and
the changes in net assets available for benefits for the years then ended in
conformity with accounting principles generally accepted in the United States of
America.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedule of assets held
for investment purposes is presented for the purpose of additional analysis and
is not a required part of the basic 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 has been subjected to the auditing procedures
applied in the audits of the basic financial statements and, in our opinion, is
fairly stated in all material respects in relation to the basic financial
statements taken as a whole.

                         Notes to Financial Statements

                          December 31, 2000 and 1999

(1)  General Information

     On June 28, 1996, Triangle Pacific Corp. (the Company) acquired from
     Premark International, Inc. (Premark) all of the common stock of Hartco
     Flooring Company. In connection with this acquisition, Premark and the
     Company agreed to spin off, effective as of June 28, 1996, that portion of
     the Premark Plan benefiting participants who were employees or former
     employees of Premark, to a separate plan sponsored and maintained by the
     Company to be known as the Hartco Flooring Company Retirement Savings Plan
     (the Plan), as set forth herein, as a continuation, without interruption,
     of such portion of the Premark Plan.

     On July 22, 1998, Triangle Pacific Corp. was acquired by Armstrong World
     Industries, Inc. (a subsidiary of Armstrong Holdings, Inc.). The Board of
     Directors of Triangle Pacific Corp. intends to continue providing
     retirement benefits through the Company's defined contribution plans.

(2)  Description of the Plan

    The following description of the Plan provides only general information.
    Participants should refer to the Plan documents for more detailed
    information.

    (a)  General

         The Plan is a defined contribution plan which provides retirement
         benefits to employees of Hartco Flooring Company, a division of
         Triangle Pacific Corp., who are not members of a collective bargaining
         agreement and whose customary employment is for at least 1,000 hours
         during a 12 month period. Employees are eligible to participate in the
         Plan on the first day of the month coincident with or following the
         completion of six months of service. All eligible employees whose
         customary employment is not for at least 1,000 hours during a year
         participate in the plan on the first day of the month coincident with
         or following the 12 month period after their employment or any plan
         year thereafter, provided 1,000 hours of service are completed during
         this time period. However, employees must not be active participants in
         any other defined contribution plan to which the Company or any
         subsidiary contributes on their behalf. The Plan is administered by
         Hartco Flooring Company, a subsidiary of Triangle Pacific Corp., and
         advised by the Company's Retirement Committee appointed by the Board of
         Directors of the Company. The Plan is subject to the provisions of the
         Employee Retirement Income Security Act of 1974 (ERISA).

    (b)  Contributions

         Participants are permitted to contribute from 1% to 16% of their
         eligible compensation to the Plan, as defined by the Plan documents.
         Participants may elect to invest their contributions in any of the
         available investment funds offered by Fidelity Management Trust
         Company, the Trustee. Effective January 1, 2000, the Company provides a
         50% match of active participants' contributions, up to 6% of the
         participant's eligible compensation.

                          December 31, 2000 and 1999

     and an allocation of the Company's contributions, Plan earnings and
     forfeitures of terminated participants' nonvested accounts. The benefit to
     which a participant is entitled is the benefit that can be provided from

     contributions and earnings thereon, and become fully vested in Company
     contributions and related earnings credited to their accounts based upon
     their years of vesting service as shown in the following table:

                     Years of                          Vested

     participants may allocate their contributions as follows:

      .  Armstrong Holdings, Inc. Common Stock - Effective April 1, 1999,
         the Plan was amended to include Armstrong World Industries, Inc.
         common stock as one of the investment options. On May 1, 2000,
         Armstrong Holdings, Inc. acquired the stock of Armstrong World
         Industries, Inc. An indirect holding in Armstrong World Industries,

         its asbestos liability. Triangle Pacific Corp. was not included in
         the filing. As of December 19, 2000, the Plan was amended to
         eliminate the Armstrong Holdings, Inc. Common Stock fund as an
         investment option effective with contributions made on or after

         also seeks capital appreciation when consistent with its primary
         objective.

                          December 31, 2000 and 1999

     .   Fidelity Asset Manager Fund - The Fidelity Asset Manager Fund
         strives for high total return with reduced risk over the long
         term. The fund pursues this goal with diversified investments of
         stocks, bonds and short-term and money market instruments, both
         domestic and international, while maintaining a diversified mix
         of securities.

     .   Fidelity Retirement Money Market Fund - The Fidelity Retirement
         Money Market Fund seeks to earn a high level of current income
         while maintaining a stable $1.00 share price by investing in
         high-quality, short- term securities. These securities may include,
         but are not limited to, high-quality short-term U.S. dollar
         denominated money market securities, domestic and foreign issuers.

(f)  Participant Loans

     Participants may borrow from the Plan an amount greater than $1,000 but
     less than 50% of the participant's vested account balance. In no event can
     the participant borrow more than $50,000. Loans are for a period not to
     exceed five years and bear interest at 1% above the prime rate of interest
     being charged by local banks at the time the loan is authorized. The
     interest rate at December 31, 2000 was 10.50%.

(g)  Payment of Benefits

     On termination of service due to death, disability or retirement, a
     participant may elect to receive the total value of their account
     attributable to their contributions, as well as the vested value of their
     Company contributions, in cash or by purchasing an annuity under the terms
     of an annuity contract. For termination of service due to other reasons, a
     participant may receive the value of the vested interest in his or her
     account as a lump sum distribution. Participants may make hardship
     withdrawals from their earnings deferred contributions at specified times,
     subject to the determination by the Plan administrator that the withdrawal
     is required to meet an immediate and heavy financial need.

(h)  Forfeitures

     Company contributions forfeited by terminating employees are used to reduce
     future Company contributions to the Plan ($6,708 and $10,881 in 2000 and
     1999, respectively). The Company will reinstate forfeited balances to the
     accounts of participants who rejoin the Company within five years of their
     termination.

(3)  Summary of Significant Accounting Policies

     (a)  Basis of Accounting

          The financial statements of the Plan are prepared under the accrual
          method of accounting.

     (b)  Investment Valuation and Income Recognition

          The Plan's investments are stated at fair value and have been
          determined based on closing market quotations. Purchases and sales of
          securities are recorded by the trustee at current cost on the trade
          date. Realized and unrealized gains (losses) on investments are based
          on the fair value of the assets at the beginning of the Plan year or
          at the time of purchase during the year. Interest income is recorded
          on the accrual basis. Dividends are recorded on the ex-dividend date.

     (c)  Administration Expenses

          In accordance with the provisions of the Plan, unless paid by the
          Company, all costs of administering the Plan are charged to the Plan.
          During 2000 and 1999, all significant expenses were paid by the
          Company ($16,087 in 2000 and $18,305 in 1999, respectively).

     (d)  Payment of Benefits

          Benefits are recorded when distributed.

     (e)  Rollover Contributions

          Employee rollovers represent receipts from employees receiving
          distributions from their previous employers' qualified plan(s).

     (f)  Use of Estimates

          The preparation of financial statements in conformity with accounting
          principles generally accepted in the United States of America requires
          management to make estimates and assumptions that affect the reported
          amounts of assets, liabilities and changes therein, and disclosure of
          contingent assets and liabilities. Actual results could differ from
          those estimates.

                           December 31, 2000 and 1999

(6)  Tax Status of the Plan

     The Internal Revenue Service has determined and informed the Company by a
     letter dated January 27, 1998, that the Plan and related trust are designed
     in accordance with applicable requirements of the Internal Revenue Code
     (IRC). The Plan has been amended since receiving the determination letter.
     However, the Plan administrator and Plan's management believe that the Plan
     is designed and is currently being operated in compliance with the
     applicable requirements of the IRC.

(7)  Plan Termination

     Although it has not expressed intent to do so, the Company has the right to
     discontinue its contribution at any time and to terminate the Plan subject
     to the provisions of ERISA. In the event of Plan termination, participants
     will become fully vested in their accounts.

(8)  Related Party Transactions

     Certain Plan investments are shares of common stock of Armstrong Holdings,
     Inc. and shares of mutual funds managed by Fidelity Investments. Triangle
     Pacific Corp. is a wholly-owned subsidiary of Armstrong World Industries,
     Inc. Fidelity Management Trust Company is the trustee as defined by the
     Plan. Therefore, transactions involving these entities or funds qualify as
     party-in-interest transactions.
