                          Independent Auditors' Report
                          ----------------------------


To the Profit Sharing Committee of the
   Robbins Hardwood Flooring, Inc.
   Employees' Retirement Savings Plan:



We have audited the accompanying statements of net assets available for benefits
of the Robbins Hardwood Flooring, Inc. Employees' Retirement Savings Plan as of
December 31, 2000 and 1999, and 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 Robbins
Hardwood Flooring, Inc. Employees' 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.

                       EMPLOYEES' RETIREMENT SAVINGS PLAN

                          Notes to Financial Statements

                           December 31, 2000 and 1999

(1)  General Information

     The Robbins Hardwood Flooring, Inc. Employees' Retirement Savings Plan (the
     Plan) became effective on March 28, 1997. 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 document for more detailed
     information.

     (a)  General

          The Plan is a defined contribution plan which provides retirement
          benefits to employees of the Triangle Pacific Corp. (the Plan
          administrator or the Company) Robbins Hardwood Flooring, Inc. division
          who are not members of a collective bargaining agreement who work at
          least 1,000 hours annually, with new participants required to be at
          least 21 years of age and employed by the Company at least one year.
          The Plan is administered by Triangle Pacific Corp. and advised by the
          Retirement Committee appointed by the Board of Directors. The Plan is
          subject to the provisions of the Employee Retirement Income Security
          Act of 1974 (ERISA).

     (b)  Contributions

          Participants are permitted to contribute up to 16% of their eligible
          compensation to the Plan, as defined by the committee. Participants
          may elect to invest their contributions in any of the available
          investment funds offered by the Fidelity Management Trust Company, the
          Trustee. Participants are able to direct all contributions to their
          account in 25% increments to the investment funds offered by the
          Trustee.

          Effective November 1, 1999, the Plan was amended to increase the
          employer matching contribution of 25% for qualified employee
          contributions up to 6% of the participant's eligible compensation for
          members of a collective bargaining agreement. Effective January 1,
          2000, the Plan increased the employer matching percentage to 50% of
          qualified employee contributions up to 6% of the employee's annual
          earnings for all participants who are not covered under a collective
          bargaining agreement. Additionally, the Plan includes a profit sharing
          component. The Company may contribute a discretionary profit sharing
          amount solely at the discretion of the Board of Directors. The Board
          of Directors approved discretionary profit sharing contributions
          totaling $131,607 and -0-, for the plan years ended December 31, 2000
          and 1999, respectively.

                          Notes to Financial Statements

                           December 31, 2000 and 1999

     (c)  Participant Accounts

          Each participant's account is credited with the participant's
          contribution and an allocation of the Company's contributions, Plan
          earnings, and forfeitures of terminated participants' non-vested
          accounts. Allocations to participant accounts are based on the
          participant's annual earnings for profit sharing contributions. The
          benefit to which a participant is entitled is the benefit that can be
          provided from the participant's vested account.

     (d)  Vesting

          Participants are fully vested in their voluntary contributions plus
          actual earnings thereon. Employee vesting in the Company's matching
          and profit sharing contributions is based on the participant's years
          of service with the Company. The participants are vested on an
          incremental basis. The participants become 20% vested after one year
          of service. The vesting percentage increases 20% a year until becoming
          fully vested after five years of service.

     (e)  Investment Options

          Elective and nondeductible contributions may be invested in a
          guaranteed income fund, fixed income funds, equity funds or a money
          market fund at the option of the participating employee. The Plan has
          investment options available to which 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, Inc. makes up
                    substantially all of the assets of Armstrong Holdings, Inc.
                    Armstrong Holdings, Inc. is publicly traded on the New York
                    Stock Exchange. On December 6, 2000, Armstrong World
                    Industries, Inc. filed a voluntary petition for relief under
                    Chapter 11 of the U.S. Bankruptcy Code in Wilmington, DE in
                    order to use the court-supervised reorganization process to
                    achieve a resolution of 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 December 27,
                    2000 and transfers processed on or after January 1, 2001.

               .    Fidelity Magellan Fund - The Fidelity Magellan Fund is a
                    diversified portfolio of common stocks of domestic and
                    foreign issuers. The portfolio seeks capital appreciation by
                    investing in growth stocks, value stocks or both.

                    grade debt securities with maturities between three to ten

          Participants may borrow from the Plan an amount 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, except for loans to acquire any dwelling to be used as the
          principal residence for the participant, and bear interest at a
          reasonable rate as established by the Plan Administrator. 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 either a lump-sum distribution, or a
          rollover into another investment. The timing of the lump-sum payment
          will be determined by the Plan administrator or disbursed as soon as
          administratively feasible upon filing a notice with the Employee
          Benefits Department. 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 ($6,339 and $8,421 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 ($8,526 in 2000 and $9,203 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.
