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


The Retirement Committee
Armstrong World Industries, Inc.:

We have audited the accompanying statements of net assets available for benefits
of the Retirement Savings and Stock Ownership Plan of Armstrong World
Industries, Inc. as of September 30, 2000 and 1999 and the related statements of
changes in net assets available for benefits for each of the years in the
two-year period ended September 30, 2000. 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 Retirement
Savings and Stock Ownership Plan of Armstrong World Industries, Inc. as of
September 30, 2000 and 1999 and the changes in net assets available for benefits
for each of the years in the two-year period ended September 30, 2000, 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 as of September 30, 2000 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. This supplemental schedule is the responsibility of the
Plan's management. 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.

                THE RETIREMENT SAVINGS AND STOCK OWNERSHIP PLAN
                      OF ARMSTRONG WORLD INDUSTRIES, INC.
                         Notes to Financial Statements

(1)  Summary of Significant Accounting Policies
     ------------------------------------------

     (a)  Basis of Presentation
          ---------------------

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

          The preparation of financial statements in conformity with generally
          accepted accounting principles in the United States of America
          requires management to make estimates and assumptions that affect the
          reported amounts of assets and liabilities and disclosure of
          contingent assets and liabilities at the date of the financial
          statements and the reported amounts of revenues and expenses during
          the reporting period. Actual results could differ from estimates
          recorded. Certain prior year amounts have been reclassified to conform
          to the current presentation.

     (b)  Investments in Master Trust
          ---------------------------

          The money market portfolio is stated at cost, which approximates fair
          value. The interest income fund is comprised of guaranteed interest
          rate contracts within the Master Trust which are fully benefit
          responsive; and therefore are reflected at contract value plus
          credited interest in the financial statements. The value of the
          participant loans represents the unpaid principal of employee loans.
          The value of all other investments is based on quoted market price.

          Securities transactions are recognized on the settlement date (the
          date on which payment for a buy or sell order is made or received),
          since adjustment to a trade-date basis would not be material. Dividend
          income is recorded on the ex-dividend date.

          Realized gains and losses on investments are determined by the average
          cost method.

          Employee Stock Ownership Funds
          ------------------------------

          Investments in the Employee Stock Ownership Funds represent shares of
          Armstrong common stock valued at quoted market price. Cash equivalents
          are stated at cost, which approximates fair value.

     (c)  Expenses
          --------
          All legal, accounting and administrative expenses associated with Plan
          operations are paid by Armstrong World Industries, Inc. ("Armstrong")


(2)  Plan Description
     ----------------

     The Retirement Savings and Stock Ownership Plan of Armstrong World
     Industries, Inc. ("the Plan") is a defined-contribution plan established
     for the purpose of providing participants a means for long-term savings
     intended for the accumulation of retirement income in addition to that
     provided under other retirement plans maintained for the benefit of
     employees. The Plan is comprised of two parts--Retirement Savings Plan and
     Employee Stock Ownership Plan (ESOP). Each part has its own set of
     participant accounts and investment funds.

                THE RETIREMENT SAVINGS AND STOCK OWNERSHIP PLAN
                      OF ARMSTRONG WORLD INDUSTRIES, INC.
                  Notes to Financial Statements, (Continued)

     (a)  Retirement Savings
          ------------------
          Separate balances are maintained for contributions made by or on
          behalf of a participant. The balances in each fund reflect the
          participants' contributions together with dividends, interest, other
          income, and realized and unrealized gains and losses allocated
          thereon.

          Each participant may have up to five accounts that make up the
          participant's total balance:

               Sheltered account - Participants may contribute from 1% to 15% of
               -----------------
               before-tax compensation as deferred compensation, as permitted
               under Section 401(k) of the Internal Revenue Code.

               Standard account - Participants may contribute from 1% to 10% of
               ----------------
               after-tax compensation.

               Rollover account - Participants may invest any untaxed amounts
               ----------------
               rolled over from another tax-qualified, employer-sponsored plan.

               Tax-deductible account (MIRA) - This account holds any
               ----------------------------
               contributions made to the Plan before January 1, 1987. No new
               contributions can be made to this account.

               Old Match account - This account holds any amount contributed by
               -----------------
               Armstrong before matching contributions were discontinued. No new
               contributions are being made to this account.

          Participants have an immediate 100 percent vested interest with
          respect to their contributions and are fully vested with regard to any
          previously made matching Armstrong contributions.

     (b)  Stock Ownership
          ---------------
          The ESOP portion of the Plan has three accounts maintained for each
          member for contributions and allocations of shares of Armstrong common
          stock from the Unallocated Armstrong Common Stock Fund.

          Participants who elect to reduce their before-tax compensation in
          amounts ranging from one percent to six percent have these
          contributions credited to an Exchange Account. Contributions to the
          Exchange Account are invested in Armstrong common stock. The Plan
          matches a portion of the contributions made to the Exchange Account
          with additional shares of Armstrong common stock. The matching amounts
          are recorded in participants' Match Accounts. The match percentage,
          either 50% or 75%, is determined by the closing stock price on the
          last day of the allocation period. For the allocation periods ended in
          December 1998, June 1999, December 1999, and June 2000 there was a 50%
          fixed match on employee Exchange Account contributions.

          Eligible participants also receive shares of Armstrong common stock in
          their Equity Account. The Equity Account is intended to provide a
          source of funds to replace certain retiree medical benefits which were
          phased out in conjunction with the adoption of the ESOP.

          Participants have an immediate 100 percent vested interest in the full
          value of their Exchange Account. Interest in the Equity and Match
          Accounts vest after five years of service.

(b)  Stock Ownership Funds
     ---------------------
     According to the terms of the trust agreement between Mellon Bank, N.A.
     through January 31, 2000 and The Chase Manhattan Bank ("the Trustee")
     beginning February 1, 2000, and Armstrong World Industries, Inc., the
     Trustee manages a trust fund that has been created under the Plan and has
     been granted authority to purchase and sell Armstrong common stock as is
     necessary to administer the Plan in accordance with its terms.

     At September 30, 2000, the investment in Armstrong common stock represents
     5,057,494 shares, valued at a quoted market price of $11.9375. There are
     2,717,577 shares held in the Allocated Armstrong Stock Fund and 2,339,917
     shares held in the Unallocated Armstrong Stock Fund. During 2000, aggregate
     proceeds on sales were $19,212,615, aggregate costs were $22,250,660, and
     the realized loss was $3,038,045. Gains of $194,215 were realized during
     1999.

                  RETIREMENT SAVINGS AND STOCK OWNERSHIP PLAN
                      OF ARMSTRONG WORLD INDUSTRIES, INC.
                  Notes to Financial Statements, (Continued)

(4)  Armstrong Contributions
     -----------------------
     Armstrong is obligated to make semi-annual contributions in cash or
     Armstrong stock to the Stock Ownership Funds, on June 15 and December 15 of
     each year, which when aggregated with all exchange contributions, dividends
     received by the Trustee on the common stock held by the Trust, and trust
     earnings, is at least equal to the amount necessary to enable the Trustee
     to pay currently maturing obligations under the Guaranteed ESOP notes (Note
     6). The contributions from Armstrong on December 15, 1999 and June 15, 2000
     included 199,053 and 237,500 shares respectively of Armstrong common stock
     contributed directly to allocated accounts.

(5)  Employee ESOP Contributions and Dividends
     -----------------------------------------
     Employee ESOP contributions made during the year and dividends paid on
     Allocated Armstrong Stock are initially deposited into the Fidelity
     Retirement Money Market Portfolio until the next semi-annual allocation
     date, at which time they are contributed to the ESOP. During the time in
     the Fidelity Retirement Money Market Portfolio, these funds earn interest.
     At September 30, 2000 and 1999, the amounts in the Fidelity Retirement
     Money Market Portfolio to be contributed to the ESOP were $3,553,389 and
     $3,609,424, respectively. Shares allocated to employees on December 15,
     1999 and June 15, 2000 included 33,448 and 208,716 shares respectively of
     Armstrong common stock that were purchased by the Trustee on the open
     market using employee ESOP contributions.

(6)  Guaranteed ESOP Notes and Loans Due Plan Sponsor
     ------------------------------------------------
     The shares of Armstrong common stock held in the Plan's Stock Ownership
     Accounts were purchased from Armstrong from the proceeds of the sale of
     Guaranteed ESOP notes in a total principal amount of $270,000,000 in 1989.
     Armstrong has guaranteed the payment of principal and interest on the
     notes.

     The notes must be repaid in semi-annual installments with interest per
     annum at 8.35% on the Series A Guaranteed Serial ESOP Notes due 1989-2001
     and 8.92% on the Series B Guaranteed Serial ESOP notes due 2001-2004. At
     September 30, 2000, the Guaranteed ESOP notes for Series A and Series B
     were $22,115,150 and $120,043,000, respectively. At September 30, 1999, the
     Guaranteed ESOP notes for Series A and Series B were $47,392,150 and
     $120,043,000, respectively. The scheduled amortization of the notes for the
     next four plan years is as follows: 2001 - $22,115,150; 2002 - $34,442,000;
     2003 - $39,816,000; 2004 - $45,785,000.

     A refinancing loan from Armstrong is used to ensure that the number of
     shares allocated during a semi-annual allocation period is equal to the sum
     of participants' exchange, equity and match shares. At September 30, 2000,
     there were 11 loans outstanding totaling $39,864,575. Of this total,
     $12,467,408 is due on June 15, 2001, and the remainder is due at various
     dates between 2006 and 2011. At September 30, 1999, there were nine loans
     outstanding totaling $20,551,404.

     The sources of cash used to repay the Plan's debt are employee
     contributions, employer contributions, and dividends on unallocated shares.
     See Note 13.

     None of the Plan's assets have been pledged as collateral for the
     Guaranteed ESOP Notes or the Loans due to Armstrong.

                  RETIREMENT SAVINGS AND STOCK OWNERSHIP PLAN
                      OF ARMSTRONG WORLD INDUSTRIES, INC.
                  Notes to Financial Statements, (Continued)

(7)  Benefits
     --------
     (a)  Retirement Savings Accounts
          ---------------------------
          Under terms of the Plan, a participant (or a beneficiary) is eligible
          for benefits upon retirement, termination of employment, or death
          before retirement. Disbursement of the total amount credited to a
          participant's account is payable (i) in a lump sum or (ii) in the case
          of retirement, in such other manner as requested by the participant
          and approved by the Plan Administrator.

          In addition, an active employee may elect to withdraw all or any part
          of his account attributable to after-tax contributions. Before
          reaching age 59 1/2, an active employee may withdraw his pretax
          contributions from the Sheltered Account, provided he can demonstrate
          financial hardship. Such employee shall be ineligible to make
          contributions for a 12-month period. An active employee may elect to
          withdraw all or any portion of his account balance in the
          Tax-Deductible (MIRA) and Rollover Accounts.

          Under the rules of the Plan, the participant may borrow up to the
          lessor of 50% of his balance or $50,000. The money borrowed must come
          from the Sheltered, Rollover, or Standard Accounts. The amount of the
          loan is transferred to a Loan Reserve pledged as security for the loan
          and is evidenced by a promissory note payable to the Plan. Interest
          rates are determined periodically by the Retirement Committee in
          accordance with prevailing interest rates. The loans are reflected in
          the Loan Portfolio investment fund. Loan repayments are made by
          payroll deductions or in a manner agreed to by the employee and the
          Plan Administrator.

     (b)  Stock Ownership Accounts
          ------------------------
          Upon death or any other separation from service from Armstrong,
          participants are entitled to receive a distribution of their vested
          account balances. Distributions are in the form of a lump sum cash
          payment or, upon request, Armstrong common stock.

(8)  Obligation for Benefits
     -----------------------
     All the funds of the Plan are held by investing institutions appointed by
     Armstrong under a trust agreement or investment contract. Benefits under
     the Plan are payable only out of these funds. Armstrong has no legal
     obligation to make any direct payment of benefits accrued under the Plan.

     Except as may be provided in an investment contract, neither Armstrong nor
     any investing institution guarantees the funds of the Plan against any loss
     or depreciation or guarantees the payment of any benefit thereunder.
     Although Armstrong has not expressed any intent to terminate the Plan, it
     may do so at any time. In case of termination or partial termination, the
     total amount in each employee's account will be distributed as the Plan
     Administrator directs.

(9) Eligibility
    -----------
     All employees of Armstrong or of any participating affiliated Armstrong are
     eligible to participate in the Plan except for foreign nationals, leased
     employees, and those employees in a collective bargaining unit unless the
     collective bargaining agent for that unit agrees to coverage under the
     Plan.

     Eligible participants, who leave Armstrong and are later reemployed, can
     resume participation in the Plan on the date of rehire.

(10) Diversification
     ---------------
     Effective January 1, 1997, Plan participants who meet certain age and
     service requirements were granted the ability to diversify specified
     portions of their ESOP account balances in any combination of the other
     investment funds available for Retirement Savings Account balances, except
     for the Fidelity Retirement Money Market Portfolio.

(11) Federal Income Taxes
     --------------------
     By a letter dated April 21, 1998, the Internal Revenue Service has
     determined and informed the Armstrong that the Plan qualifies under the
     applicable provisions of the Internal Revenue Code and is therefore exempt
     from federal income taxes.

(12) Master Trust Agreement
     ----------------------
     Effective October 1, 1990, the Plan established a Master Trust Agreement
     with Fidelity Management Trust Company. Under the Master Trust Agreement,
     the Plan assets held by Fidelity Management Trust Company are commingled
     and invested with the assets of the Retirement Savings Plan for Hourly-Paid
     Employees of Armstrong World Industries, Inc., the Bonus Replacement
     Retirement Plan of Armstrong World Industries, Inc., the Triangle Pacific
     Corp. Salaried Employees' Profit Sharing Plan, the Triangle Pacific Corp.
     Non-union Hourly 401(k) Plan, the Robbins Hardwood Flooring Inc. Employees'
     Retirement Savings Plan, the Hartco Flooring Co. Bargaining Employees
     Retirement Savings Plan, and the Hartco Flooring Co. Retirement Savings
     Plan. Separate accounting for each plan under the Master Trust Agreement is
     provided by Fidelity Management Trust Company. The Plan has an undivided
     interest in the assets of this trust, and ownership is represented by
     proportionate dollar interest. The following summarizes the financial
     information of the Master Trust at September 30, 2000 and 1999:

(13) Subsequent Events
     -----------------

     On November 22, 2000, Armstrong failed to repay $50 million in commercial
     paper that was due. As a result, the remaining ESOP bond principal balance
     of $142.2 million became immediately payable along with a $15.5 million
     interest and tax penalty. Additionally, the December 2000 ESOP debt service
     payment was not made by either the Plan or by Armstrong.

     As of November 30, 2000 the Plan was amended such that all employee
     contributions made to the ESOP subsequent to the June 2000 allocation would
     be contributed to the Retirement Savings portion of the Plan and invested
     in funds selected by each participant. The employer contributions made in
     December 2000 were made in cash and were also invested in funds selected by
     each participant. Dividends held by the Trustee related to the unallocated
     shares were transferred to the Retirement Savings portion of the Plan in
     partial satisfaction of the employer match. Future employee and employer
     contributions to the ESOP were suspended, and a Company cash match of 50%
     of employee Sheltered Account contributions up to 6% was added to the
     Retirement Savings portion of the Plan, effective as soon as
     administratively possible.

     On December 6, 2000, Armstrong 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. On December 6, 2000, Armstrong filed a motion with the
     bankruptcy court to allow Armstrong to continue making contributions to the
     Plan. The motion was approved by the court. Management does not anticipate
     that Armstrong's bankruptcy filing will have an adverse impact on the
     operations of the Plan.

     As of December 19, 2000 the Plan was amended to allow all participants,
     regardless of age and vested status, to fully diversify their ESOP
     accounts. The amendment also eliminated the Armstrong 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.
