(In thousands, except share and per-share data) Note 1. Summary of Accounting Policies Description of Business The company operates in four business segments -lighting equipment, textile rental, chemicals, and envelopes- which are leading competitors in their respective markets. The lighting equipment segment produces a variety of fluorescent and non-fluorescent fixtures for markets throughout the United States, Canada, Mexico, and overseas. The textile rental segment provides linens and dust control products to healthcare, lodging, and dining customer segments in the United States. The chemical segment produces maintenance, sanitation, and water treatment products for customers throughout the United States, Canada, Puerto Rico, and Western Europe. The envelope segment produces business and specialty envelopes in the South and Southwest. Principles of Consolidation The consolidated financial statements include the accounts of the company and all subsidiaries after elimination of significant intercompany transactions and accounts. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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 those estimates. Cash, Cash Equivalents, and Short-Term Investments Cash in excess of daily requirements is invested in time deposits and marketable securities, consisting of taxable and tax exempt variable rate demand notes, included in the balance sheet at market value. The company considers time deposits and marketable securities purchased with an original maturity of three months or less to be cash equivalents. Investments purchased with a maturity of more than three months are considered short-term investments. The carrying amounts of short-term investments at August 31, 1997 and 1996 approximate fair value. At August 31, 1997, short-term investments consisted primarily of corporate debt securities and commercial paper. In accordance with the criteria specified by Statement of Financial Accounting Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt and Equity Securities," these investments were classified as "available for sale." Concentrations of Credit Risk Concentrations of credit risk with respect to receivables are limited due to the wide variety of customers and markets into which the company's products and services are provided, as well as their dispersion across many different geographic areas. As a result, as of August 31, 1997, the company does not consider itself to have any significant concentrations of credit risk. Inventories and Linens in Service Inventories are valued at the lower of cost (on a first-in, first-out basis) or market and consisted of the following at August 31, 1997 and 1996: 1997 1996 Raw materials and supplies $ 71,266 $ 73,236 Work in progress 10,572 9,679 Finished goods 97,208 86,898 $ 179,046 $ 169,813 Linens in service are recorded at cost and are amortized over their estimated useful lives of 15 to 50 months. Goodwill and Other Intangibles Goodwill of $3,460 was recognized in connection with a 1969 acquisition and is not being amortized. Remaining amounts of goodwill ($34,974 in 1997 and $45,029 in 1996) and other intangible assets are being amortized on a straight-line basis over various periods up to 40 years. 8 The company periodically evaluates whether events and circumstances have occurred that may warrant revision of the estimated useful lives of goodwill and other long-lived assets or whether the remaining balance of goodwill should be evaluated for possible impairment. The company uses an estimate of related undiscounted cash flows over the remaining life of the goodwill in measuring whether the goodwill is recoverable. During fiscal 1997, goodwill and other intangibles of $8,800 were written off due to the impairment of long-lived assets (Note 5). Depreciation For financial reporting purposes, depreciation is determined principally on a straight-line basis using estimated useful lives of plant and equipment (25 to 45 years for buildings and 3 to 16 years for machinery and equipment) while accelerated depreciation methods are used for income tax purposes. Leasehold improvements are amortized over the life of the lease or the useful life of the improvement, whichever is shorter. -32- 9 Page 32 Exhibit 13 Notes to Consolidated Financial Statements (continued) National Service Industries, Inc. Foreign Currency Translation The functional currency for the company's foreign operations is the local currency. The translation of foreign currencies into U.S. dollars is performed for balance sheet accounts using exchange rates in effect at the balance sheet date and for revenue and expense accounts using a weighted average exchange rate during the period. The gains or losses, net of applicable income taxes, resulting from the translation are included in retained earnings and are excluded from net income. Gains or losses resulting from foreign currency transactions are included in "Other expense, net" in the consolidated statements of income and amounted to a loss of $54 in 1997 and gains of $249 in 1996 and $201 in 1995. Pension and Profit Sharing Plans The company has several pension plans covering hourly and salaried employees. Benefits paid under these plans are based generally on employees' years of service and/or compensation during the final years of employment. The company makes annual contributions to the plans to the extent indicated by actuarial valuations. Plan assets are invested primarily in equity and fixed income securities. Net pension (income) expense for 1997, 1996, and 1995 included the following components: 1997 1996 1995 Service cost of benefits earned during the period $ 3,636 $ 2,719 $ 2,648 Interest cost on projected benefit obligation 8,505 7,438 7,277 Return on plan assets (12,393) (28,255) (12,178) Net amortization and deferral (768) 17,383 2,257 Net pension (income) expense $ (1,020) $ (715) $ 4 The following schedule reconciles the funded status of the plans as of June 1, 1997 and 1996, with amounts reported in the company's balance sheets at August 31, 1997 and 1996: 1997 1996 Plan Assets Accumulated Plan Assets Accumulated Exceed Benefit Exceed Benefit Accumulated Obligation Accumulated Obligation Benefit Exceeds Plan Benefit Exceeds Plan Obligation Assets Obligation Assets Actuarial present value of benefit obligations as of June 1: Vested $(87,929) $(5,123) $(91,127) $(3,784) Nonvested (10,180) (20) (4,281) (1,407) Accumulated benefit obligation (98,109) (5,143) (95,408) (5,191) Effect of projected salary increases (5,379) (1,195) (7,431) (1,640) Total projected benefit obligation (103,488) (6,338) (102,839) (6,831) Fair value of plan assets 133,214 - 134,426 - Plan assets greater (less) than projected benefit obligation 29,726 (6,338) 31,587 (6,831) Unrecognized transition (asset) liability (7,059) 61 (9,475) 74 Unrecognized prior service cost obligation 1,873 2,208 3,056 2,528 Unrecognized net loss (gain) 9,891 (896) 6,471 (371) Adjustment required to recognize minimum liability -- (596) -- (918) Prepaid (accrued) pension expense at August 31 $ 34,431 $ (5,561) $ 31,639 $(5,518) For all periods presented, the discount rate used to determine the projected benefit obligation is 8 percent, the assumed growth rate of compensation is 5.5 percent, and the expected long-term rate of return on plan assets is 9.5 percent. The company also has profit sharing and 401(k) plans to which both employees and the company contribute. At August 31, 1997, assets of the 401(k) plans included shares of the company's common stock with a market value of approximately $13,868. The company's cost of these plans was $5,020 in 1997, $4,595 in 1996, and $3,810 in 1995. -33- 10 Page 33 Exhibit 13 Notes to Consolidated Financial Statements (continued) National Service Industries, Inc. Postretirement Healthcare and Life Insurance Benefits The company's retiree medical plans are financed entirely by retiree contributions; therefore, the company has no liability in connection with them. Several programs provide limited retiree life insurance benefits. The liability for these plans is not material. Postemployment Benefits Statement of Financial Accounting Standards (SFAS) No. 112, "Employers' Accounting for Postemployment Benefits," requires the accrual of the estimated cost of benefits provided by an employer to former or inactive employees after employment but before retirement. The company's accrual, which is not material, relates primarily to severance agreements and the liability for life insurance coverage for certain eligible employees. Interest Expense, Net Interest expense, net is comprised primarily of interest expense on long-term debt and short-term line of credit borrowings and interest income on cash, cash equivalents, and short-term investments. Other Expense, Net Other expense, net is comprised primarily of amortization of intangible assets net of gains resulting from the sale of fixed assets and casualty loss insurance proceeds. Accounting Standards Yet to Be Adopted During fiscal 1998, the company is required to adopt Statement of Financial Accounting Standards No. 128, "Earnings per Share." SFAS No. 128 supersedes Accounting Principles Board Opinion No. 15, "Earnings per Share," and promulgates new accounting standards for the computation and manner of presentation of the company's earnings per share. Earlier application is not permitted; however, upon adoption, the company will be required to restate previously reported annual and interim earnings per share in accordance with the provisions of SFAS No. 128. The adoption of SFAS No. 128 will not have a material impact on the computation or manner of presentation of the company's earnings per share as currently or previously presented under APB No. 15. During fiscal 1999, the company is required to adopt SFAS No. 130, "Reporting Comprehensive Income." SFAS No. 130 requires the reporting of a measure of all changes in equity of an entity that result from recognized transactions and other economic events other than transactions with owners in their capacity as owners. In the opinion of management, the adoption of SFAS No. 130 is not expected to have a material impact on the company's manner of reporting the components of comprehensive income. Reclassifications Certain amounts in the 1996 and 1995 financial statements and notes have been reclassified to conform with the 1997 presentation. Note 2. Long-Term Debt and Lines of Credit Long-term debt at August 31, 1997 and 1996, consisted of the following: 1997 1996 6.5% to 9.25% mortgage notes, payable in installments through 2000 (secured in part by $ 86 $ 148 property, plant, and equipment having a net book value of $237 at August 31, 1997) 3.4% to 8.5% other notes, payable in installments to 2026 26,227 24,818 26,313 24,966 Less-Amounts payable within one year included in current liabilities 116 46 $ 26,197 $ 24,920 The annual maturities of long-term debt are as follows: Amounts Year Ending August 31 1998 116 1999 100 2000 108 2001 91 2002 97 Later years 25,801 $ 26,313 Late in fiscal 1996, the company negotiated a $250,000 multi-currency committed credit facility with eleven domestic and international banks. The company had no outstanding borrowings under the facility at August 31, 1997. -34- 11 Page 34 Exhibit 13 Notes to Consolidated Financial Statements (continued) National Service Industries, Inc. The company has complimentary lines of credit totaling $62,000, of which $40,000 has been provided domestically and $22,000 is available on a multi-currency basis primarily from a European bank. At August 31, 1997, the company had foreign currency short-term bank borrowings equivalent to $5,773 at an average interest rate of 4.1%. Under the domestic line of credit, up to $40,000 may be used for letters of credit. At August 31, 1997, $16,683 in letters of credit associated with the company's insurance program (Note 4) was outstanding and $23,317 was available under the line of credit. Long-term debt recorded in the accompanying balance sheets approximates fair value based on the borrowing rates currently available to the company for bank loans with similar terms and average maturities. Note 3. Common Stock and Related Matters The company has a shareholder rights plan under which one preferred stock purchase right is presently attached to and trades with each outstanding share of the company's common stock. The rights become exercisable and transferable apart from the common stock ten days after a person or group, without the company's consent, acquires beneficial ownership of, or the right to obtain beneficial ownership of, 20 percent or more of the company's common stock or announces or commences a tender offer or exchange offer that could result in 20 percent ownership (unless such date is extended by the Board of Directors). Once exercisable, each right entitles the holder to purchase one one-hundredth share of Series A Participating Preferred Stock at an exercise price of $80, subject to adjustment to prevent dilution. The rights have no voting power and, until exercised, no dilutive effect on net income per common share. The rights expire on May 19, 1998, and are redeemable under certain circumstances. If a person acquires 20 percent ownership, except in an offer approved by the company under the plan, each right not owned by the acquirer or related parties will entitle its holder to purchase, at the right's exercise price, common stock or common stock equivalents having a market value immediately prior to the triggering of the right of twice that exercise price. In addition, after an acquirer obtains 20 percent ownership, if the company is involved in certain mergers, business combinations, or asset sales, each right not owned by the acquirer or related persons will entitle its holder to purchase, at the right's exercise price, shares of common stock of the other party to the transaction having a market value immediately prior to the triggering of the right of twice that exercise price. The company has 1,000,000 shares of preferred stock authorized, 500,000 of which have been reserved for issuance under the shareholder rights plan. No shares of preferred stock had been issued at August 31, 1997. In 1990, the stockholders approved the National Service Industries, Inc. Long-Term Incentive Program for the benefit of officers and other key employees. There were 1,750,000 treasury shares reserved for issuance under the program. In 1997, the stockholders approved the National Service Industries, Inc. Long-Term Achievement Incentive Plan for the benefit of officers and other key employees. There were 1,750,000 treasury shares reserved for issuance under that plan. The stock options granted under both the incentive programs become exercisable in four equal annual installments beginning one year from the date of the grant. In 1993, the stockholders approved the National Service Industries, Inc. 1992 Nonemployee Directors' Stock Option Plan, under which 100,000 treasury shares were reserved for issuance. The stock options granted under that plan become exercisable one year from the date of the grant. Under all stock option plans, the options expire ten years from the date of the grant and have an exercise price equal to the fair market value on the date of the grant. Stock option transactions for the stock option plans and stock option agreements during the years ended August 31, 1997, 1996, and 1995 were as follows: 1997 1996 1995 Options outstanding at September 1 1,266,043 1,088,773 820,752 Granted 324,500 513,200 325,400 Exercised 196,115 185,044 23,598 Canceled 7,214 150,886 33,781 Additional shares available for future grant 1,750,000 - - Options outstanding at August 31 1,387,214 1,266,043 1,088,773 Option price range at August 31 $19.75-$39.75 $19.75-$39.75 $19.75-$29.00 Options exercisable at August 31 731,914 466,377 513,665 Options available for grant at August 31 1,732,574 300,408 657,565 -35- 12 Page 35 Exhibit 13 Notes to Consolidated Financial Statements (continued) National Service Industries, Inc. Potential dilution of earnings per share applicable to these stock options is not significant. During fiscal 1997, the company adopted the disclosure-only provisions of Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation." Accordingly, no compensation cost has been recognized for these stock option plans. Had compensation cost for the company's stock option plans been determined based on the fair value at the grant date for awards in fiscal years 1996 and 1997 consistent with the provisions of SFAS No. 123, the company's net earnings and earnings per share would have been reduced to the following pro forma amounts: 1997 1996 Net income-as reported $107,278 $101,148 Net income-pro forma $105,793 $100,284 Earnings per share-as reported $ 2.37 $ 2.11 Earnings per share-pro forma $ 2.34 $ 2.09 The fair value of each option grant is estimated on the date of the grant using the Black-Scholes option-pricing model with the following weighted average assumptions: 1997 1996 Dividend yield 3.350% 4.009% Expected volatility 16.8% 15.3% Risk-free interest rate 6.73% 6.10% Expected life of options 10 years 10 years Turnover rate 5.0% 5.0% Note 4. Commitments and Contingencies Self Insurance It is the policy of the company to self insure for certain insurable risks consisting primarily of physical loss to property; business interruptions resulting from such loss; and workers' compensation, comprehensive general, and auto liability. Insurance coverage is obtained for catastrophic property and casualty exposures as well as those risks required to be insured by law or contract. Based on an independent actuary's estimate of the aggregate liability for claims incurred, a provision for claims under the self-insured program is recorded and revised annually. Expense associated with the program was $7,900 in 1997, $13,677 in 1996, and $22,800 in 1995. Leases The company leases certain of its buildings and equipment under noncancelable lease agreements. Minimum lease payments under noncancelable leases for years subsequent to August 31, 1997, are as follows: Amount Year Ending August 31 1998 $ 9,342 1999 7,791 2000 6,092 2001 4,433 2002 2,998 Later years 7,104 Total minimum lease payments $37,760 Total rent expense was $11,327 in 1997, $10,907 in 1996, and $11,607 in 1995. Litigation The company is involved in various legal matters primarily arising in the normal course of business. In the opinion of management, the company's liability in any of these matters will not have a material adverse effect on its financial condition or results of operations. -36- 13 Page 36 Exhibit 13 Notes to Consolidated Financial Statements (continued) National Service Industries, Inc. Note 5. Restructuring Expense and Asset Impairments During 1997, the company conducted reviews of the textile rental, European chemical, and corporate operations as a part of management's strategic initiatives to examine under-performing operations and to position the company for growth. As a result of the reviews, the company approved a significant restructuring program and recorded a related charge of $9,600 during the fourth quarter. The accrual included severance and union-related costs totaling $2,950 for 120 employees of the textile rental, chemical and envelope segments and $6,650 in exit expenses to close certain facilities and consolidate the operations of others in the textile rental segment. Exit expenses include costs of unexpired leases, costs to dispose of facilities, and costs of personnel to effect the closures and consolidations. The severance accrual had been reduced by payments of $205 and reserves associated with plant consolidations had been reduced by $1,910 as of August 31, 1997. As a further result of the reviews, the company recognized long-lived asset impairments totaling $43,500. Textile rental assets to be disposed of in under-performing branches were reduced by $22,300 to state them at their estimated fair value less costs to sell. The remaining net book value of these assets is immaterial. Fixed assets held for use by the textile rental, European chemical, and corporate units were reduced by $12,400 and related intangibles were reduced by $8,800. Impairments were recognized for those assets where the sum of estimated undiscounted future cash flows was less than the carrying amount of the assets, including related goodwill. Fair market values were established based on independent appraisals, comparable sales or purchases, and expected future cash flows discounted at the company's cost of capital. Factors leading to the impairments were a combination of the reviews discussed above, historical losses, anticipated future losses, and inadequate cash flows. The textile rental segment recorded other charges of $10,000 associated primarily with environmental matters. The associated reserves had been reduced to $8,400 at August 31, 1997. The losses resulting from the accruals and impairments are included in "Restructuring expense, asset impairments, and other charges" in the consolidated statements of income. Note 6. Divestitures and Acquisitions In February 1997, the company sold the North Bros. insulation business for $27.1 million in cash. An immaterial gain was realized on the sale. The business had 1997 sales of $57,000 and operating income of $1,900. Additionally, immaterial gains were recognized as the company divested several non-strategic textile rental locations. In July 1997, the company sold 29 textile rental plants to G&K Services, Inc. at a pretax gain of $74.0 million. The following condensed pro forma consolidated balance sheet gives effect to the sale as if the transaction had occurred at August 31, 1996: Condensed Pro Forma Consolidated Balance Sheet (Unaudited) August 31, 1996 Assets Current Assets: Cash and short-term investments $ 346,713 Receivables, net 249,823 Inventories and linens in service 228,808 Other current assets 8,645 Total Current Assets 833,989 Property, Plant, and Equipment, net 266,533 Other Assets 83,402 Total Assets $ 1,183,924 Liabilities and Stockholders' Equity Current Liabilities $ 230,191 Long-Term Debt, less current maturities 24,920 Deferred Income Taxes 63,347 Other Long-Term Liabilities 90,945 Stockholders' Equity 774,521 Total Liabilities and Stockholders' Equity $ 1,183,924 The following condensed pro forma consolidated statements of income restate reported results for the respective fiscal years to remove both the gain on the transaction and the results of the operations sold: Condensed Pro Forma Consolidated Statements of Income (Unaudited) 1997 1996 Sales and Service Revenues $ 1,859,653 $1,803,034 Other Costs and Expenses 1,708,672 1,648,460 Restructuring Expense, Asset Impairments, and Other Charges 63,091 - Income before Provision for Income Taxes 87,890 154,574 Provision for Income Taxes 32,172 57,988 Income before Gain on Disposal $ 55,718 $ 96,586 Earnings per Share $ 1.23 $ 2.01 Weighted Average Number of Shares Outstanding (thousands) 45,191 47,941 -37- 14 Page 37 Exhibit 13 Notes to Consolidated Financial Statements (continued) National Service Industries, Inc. The pro forma statements are not necessarily indicative of the financial position and results of operations that would have been attained had the divestiture been consummated on the dates indicated or that may be attained in the future. In 1997, cash acquisition spending totaled $4.3 million and was the result of the chemical segment's purchase of chemical products companies in Ohio and Canada and the lighting equipment segment's acquisition of a small emergency lighting products manufacturer in Canada. The company also issued 536,872 shares valued at $20.5 million to acquire Enforcer Products, Inc., a specialty chemical company with a retail focus. The operating results of Enforcer were included in the chemical segment beginning with the third quarter of fiscal 1997. Acquisitions during 1996 related to the textile rental segment and were not material. During 1996 and 1995, the company divested several non-strategic or unprofitable businesses, primarily in the textile rental segment, generating cash of $15,250 and $14,044, respectively. In May 1995, the company acquired the assets of Infranor Canada Inc., a Canadian lighting products manufacturer based in Saint Hyacinthe, Quebec. The operating results of Infranor were included in the lighting equipment segment for the fourth quarter of fiscal 1995. Full-year acquisition spending of $2.7 million also included several small purchases for the textile rental segment. Note 7.

The management of National Service Industries, Inc. is responsible for the integrity and objectivity of the financial information in this annual report. These financial statements are prepared in conformity with generally accepted accounting principles, using informed judgments and estimates where appropriate. The information in other sections of this report is consistent with the financial statements. The company maintains a system of internal controls and accounting policies and procedures designed to provide reasonable assurance that assets are safeguarded and transactions are executed and recorded in accordance with management's authorization. The audit committee of the Board of Directors, composed entirely of outside directors, is responsible for monitoring the company's accounting and reporting practices. The audit committee meets regularly with management, the internal auditors, and the independent public accountants to review the work of each and to assure that each performs its responsibilities. Both the internal auditors and Arthur Andersen LLP have unrestricted access to the audit committee allowing open discussion, without management's presence, on the quality of financial reporting and the adequacy of internal accounting controls. James S. Balloun Chairman, President, and Chief Executive Officer Brock A. Hattox Executive Vice President and Chief Financial Officer Mark R. Bachmann Vice President and Controller Report of Independent Public Accountants To the Stockholders of National Service Industries, Inc.: We have audited the accompanying consolidated balance sheets of National Service Industries, Inc. (a Delaware corporation) and subsidiaries as of August 31, 1997 and 1996 and the related consolidated statements of income, stockholders' equity and cash flows for each of the three years in the period ended August 31, 1997. 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 generally accepted auditing standards. 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 National Service Industries, Inc. and subsidiaries as of August 31, 1997 and 1996 and the results of their operations and their cash flows for each of the three years in the period ended August 31, 1997 in conformity with generally accepted accounting principles. Arthur Andersen LLP Atlanta, Georgia October 20, 1997 -40- 17 Page 40 Exhibit 13 Management's Discussion and Analysis of Financial Condition and Results of Operations National Service Industries, Inc. Financial Condition National Service Industries maintained a strong financial position at August 31, 1997. Net working capital was $498.8 million, up from $409.0 million at August 31, 1996, and the current ratio was 2.8, compared with 3.1 at the prior year end. Cash and short-term investments increased to $262.4 million, from $59.2 million last August, largely as a result of the cash realized on the sale of 29 textile rental plants to G&K Services, Inc. in July 1997. During 1997, the company invested $53.1 million in capital expenditures and acquisitions. The percent of short-term and long-term debt to total capitalization was 4.6 percent at August 31, 1997 and 4.2 percent at the prior year end. Cash provided by operating activities was $127.6 million, compared to $153.0 million in 1996 and $145.9 million in 1995. The 1997 decrease resulted primarily from investment in inventories to support increased sales of the lighting equipment segment and changes in deferred taxes associated with the textile rental divestiture. The 1996 improvement was due in large part to better management of inventories and higher net income. Capital expenditures, exclusive of acquisition spending, were $48.8 million in 1997, $65.5 million in 1996, and $58.8 million in 1995. During both 1997 and 1996, the lighting equipment segment invested in facility and process improvements, equipment replacements, and tooling for new products. 1996 spending also included expansion of the segment's production facility in Monterrey, Mexico. The textile rental segment made substantial investments in facility improvements and replacement of equipment during 1997 and 1996. Cash payments in connection with acquisitions totaled $4.3 million in 1997, $.6 million in 1996, and $2.7 million in 1995. In 1997, the chemical segment purchased chemical products companies in Ohio and Canada, and the lighting equipment segment acquired a small emergency lighting products manufacturer in Canada. The company also issued 536,872 shares valued at $20.5 million to acquire Enforcer Products, Inc., a specialty chemical company with a retail focus. The operating results of Enforcer were included in the chemical segment beginning with the third quarter of fiscal 1997. The two prior years included spending for small acquisitions of the textile rental segment. In 1995, the company also acquired the assets of Infranor Canada Inc., a Canadian lighting products manufacturer based in Saint Hyacinthe, Quebec. The operating results of this acquisition were included in the lighting equipment segment beginning with the fourth quarter of fiscal 1995. In February 1997, the company sold the North Bros. insulation business for $27.1 million in cash. An immaterial gain was realized on the sale. The business had 1997 sales of $57.0 million and operating income of $1.9 million through the date of sale. Additionally, immaterial gains were realized as the company divested several non-strategic textile rental locations. In July 1997, the company sold 29 textile rental plants to G&K Services, Inc. for approximately $280 million in cash, resulting in a pretax gain of $74.0 million. The divested locations had 1997 sales of $176.5 million and operating income of $9.4 million through the date of sale. During 1996 and 1995, the company divested several non-strategic businesses, primarily in the textile rental segment, generating cash of $15.3 million and $14.0 million, respectively. During 1997, the company distributed 164 percent of net income to shareholders through dividends and share repurchases. A total of 2,727,000 shares were purchased under the company's standing annual authorization to repurchase 2.0 million shares plus the number of new shares issued in any one year. An additional 273,000 shares were purchased under the 1997 supplemental authorization for 1.25 million shares granted as a result of the textile rental divestiture transaction. Last year, the company spent $75.2 million on the repurchase of 2.0 million shares of its common stock. Dividend payments totaled $54.2 million, or $1.19 per share, in 1997, $55.3 million, or $1.15 per share, in 1996, and $54.2 million, or $1.11 per share, in 1995. The fiscal 1997 dividend of $1.19 per share was a 3.4 percent increase. -41- 18 Page 41 Exhibit 13 Management's Discussion and Analysis of Financial Condition and Results of Operations (continued) National Service Industries, Inc. For the periods presented, capital expenditures, working capital needs, dividends, acquisitions, and share repurchases were financed primarily with internally generated funds and some 1997 interim borrowing against the committed credit facility (discussed below). European operations were supplemented by short-term borrowings in the European market. Contractual commitments for capital and acquisition spending for fiscal 1998 total $22.6 million. The company expects actual capital expenditures in 1998 to be somewhat higher than the 1997 level. Late in fiscal 1996, the company negotiated the $250 million multi-currency committed credit facility with eleven domestic and international banks. The company has complimentary lines of credit totaling $62 million, of which $40 million has been provided domestically and $22 million is available on a multi-currency basis primarily from a European bank. Current liquid assets, internally generated funds, and the available credit are expected to meet the anticipated general operating cash requirements for the next twelve months. Results of Operations National Service Industries posted record revenues of $2.04 billion for the fiscal year ended August 31, 1997. Total year revenues increased $22.6 million, or 1.1 percent, from $2.01 billion in 1996, resulting from higher volumes in the lighting equipment, chemical, and envelope segments. Revenues for 1996 increased $42.9 million, or 2.2 percent, from $1.97 billion in 1995, primarily as a result of higher pricing in the lighting equipment segment and volume gains across the chemical and envelope segments. Net income for fiscal 1997 increased $6.1 million, or 6.1 percent, to $107.3 million, or $2.37 per share. Earnings per share grew at the greater rate of 12.5 percent due to a reduction of 2.8 million in average shares outstanding. For fiscal 1996, net income grew 7.5 percent to $101.1 million, or $2.11 per share. Lighting equipment segment sales grew 9.7 percent to $952 million from $868 million in 1996. Net income rose 21.4 percent to 9.7 percent of revenues. Higher unit volumes, primarily in the non-residential construction market, contributed to the increase in sales and, combined with improved mix and lower manufacturing costs, drove income higher. Sales for 1996 increased 1.9 percent from 1995 on the strength of pricing gains that were somewhat offset by lower unit volumes. For 1996, operating profit advanced 24.1 percent to 8.8 percent of revenues, compared with 7.2 percent of revenues in 1995. 1996 margin improvements resulted from a more favorable product mix and lower manufacturing costs. Textile rental segment revenues for 1997 decreased 7.0 percent to $494 million primarily as a result of the businesses divested. For 1997, operating income increased 44.1 percent to $60.8 million. The $75.1 million gain on the sale of plants was offset by restructuring expenses, asset impairments, and other charges totaling $49.6 million. A review of the segment's under-performing and non-strategic locations resulted in a plan to dispose of certain plants and consolidate the operations of others. Restructuring expenses included severance and union-related expenses of $1.2 million and exit expenses of $6.7 million for unexpired leases, costs to dispose of facilities, and costs of personnel to effect the closures and consolidations. Also as a result of the review and due to a combination of historical losses, anticipated future losses, and inadequate cash flows, the segment recorded an impairment loss of $22.3 million on assets to be disposed of and $9.5 million on assets held for use. After the impairment charge, the remaining net book value of the assets to be disposed of was immaterial. The benefits of these actions, primarily due to reduced employee and facility expenses, will be partially offset by the costs of plant consolidations over the next several years and will grow from approximately $3.0 million in fiscal 1998 to roughly $6.0 million in fiscal 2001. The restructuring is not expected to materially impact future liquidity or other sources and uses of capital. -42- 19 Page 42 Exhibit 13 Management's Discussion and Analysis of Financial Condition and Results of Operations (continued) National Service Industries, Inc. Textile rental segment revenues for 1996 were $531 million, compared with $546 million in 1995, and reflected lost sales from divested branches and continued price pressure. Operating income decreased 17.3 percent to 8.0 percent of revenues, compared with 9.3 percent of revenues in 1995, as a result of lower selling prices and cost increases for labor and merchandise, which were partially offset by lower workers' compensation costs and one-time gains on asset sales. Chemical segment revenues for 1997 grew 9.5 percent to $403 million, from $368 million in 1996, as a result of incremental volumes from U.S. and Canadian acquisitions. Operating income declined as a percent of sales due to higher manufacturing costs and investments to increase the size and capability of the segment's fully commissioned sales force. A study of the segment's European operations resulted in a severance-related charge of $1.5 million for operational reorganizations and an asset impairment loss of $8.1 million resulting from historical losses and inadequate future cash flows. Fiscal 1996 revenues advanced 4.3 percent to $368 million, from $353 million in 1995. The gains resulted from higher unit volumes, predominantly in domestic operations. Fiscal 1996 operating income grew 9.6 percent to 10.6 percent of revenues, from 10.0 percent of revenues in 1995, as margins benefited from the volume increases and lower material and operating costs. Envelope segment 1997 sales increased 4.1 percent to $131 million from $126 million in 1996 and $110 million in 1995. The impact of volume gains earlier in the year was reduced by contractual price adjustments in the fourth quarter due to reduced paper costs. Operating profit was only slightly ahead of 1996 levels due to increased manufacturing costs associated with the segment's growth initiatives. 1995 operating profit grew as a result of volume increases. The decrease in sales and operating profits of the "other" category reflects the divestiture of the insulation service business in February 1997. Corporate income declined $7.4 million in 1997 due to the fourth quarter asset impairment recorded to reflect the $1.2 million appraised value of an asset held for sale and due to accrued incentive plan costs. Corporate income increased in 1996 and declined in 1995 mainly because of 1995 accruals for higher business taxes. During all periods presented, the company benefited from higher average levels of short-term investments. Foreign currency exchange rate fluctuations were unfavorable in 1997, compared with favorable results in 1996 and 1995. Net interest expense varied only slightly for the three years presented. Consolidated income before taxes grew 10.6 percent and net income grew 6.1 percent in 1997. Excluding unusual gains and expenses, improvement resulted primarily from growth in the lighting equipment segment. In 1996, consolidated income before taxes and net income grew 7.5 percent, compared with 13.8 percent for both measures in 1995. The 1996 decline was due primarily to a lower rate of growth in segment operating profits. The 1997 provision for income taxes was 40.1 percent of pretax income, compared with 37.5 percent in 1996 and 1995. The increase in the 1997 rate was due mainly to the higher rate applicable to the gain on the textile rental divestiture. Outlook Fiscal 1997 was a year in which NSI solidified its vision of its businesses and took actions to position the company for the future. Fiscal 1998 sales are anticipated to be down slightly due to the lost sales of the divested businesses. Sales growth of continuing businesses is expected to exceed 5.0 percent, given the continued strength in the lighting equipment market and growth initiatives in the chemical and envelope segments. NSI will continue to invest for future profitable growth of the remaining businesses and to increase the pace of acquisitions. The year-over-year gain in earnings per share is expected to be in line with 1997's growth performance. -43- 20 Page 43 Exhibit 13 Ten-Year Financial Summary National Service Industries, Inc.
