The accompanying notes are an integral part of these financial statements. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS JUNE 30, 1998 1. CONSOLIDATION AND PRESENTATION The accompanying unaudited condensed consolidated financial statements of MasTec, Inc. ("MasTec" or the "Company") have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions for Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all information and notes required by generally accepted accounting principles for complete financial statements and should be read in conjunction with the audited financial statements and notes thereto included in the Company's annual report on Form 10-K for the year ended December 31, 1997. The year end condensed balance sheet data was derived from audited financial statements but does not include all disclosures required by generally accepted accounting principles. The financial information furnished reflects all adjustments, consisting only of normal recurring accruals which are, in the opinion of management, necessary for a fair presentation of the financial position and results of operations for the periods presented. The results of operations are not necessarily indicative of future results of operations or financial position of MasTec. Certain prior year amounts have been reclassified to conform to the current presentation. During the second quarter of 1998, the Company's management applied purchase accounting to two 1997 acquisitions previously accounted for using pooling-of-interests. The change occurred due to transactions with management of the acquired companies which occurred in the second quarter of 1998 and future compensation arrangements currently under consideration that may have required the use of purchase accounting. The change in accounting resulted in an increase to capital surplus and intangible assets of $53 million. No other significant changes to previously reported balance sheet amounts were recorded. The resulting goodwill will be amortized over 40 years. As a result, second quarter and first half results in 1998 include amortization expense of $333,000 and $667,000, respectively, related to additional amortization expense from the change in accounting method. As a result of the application of purchase accounting, the Company's 1997 results by quarter were:
First Quarter Second Quarter Third Quarter Fourth Quarter Total Revenue $ 130,143 $ 141,499 $ 184,562 $ 203,235 $ 659,439 Operating income 15,495 17,614 16,772 7,602 57,483 Net income 9,287 10,826 8,498 6,053 34,664 Basic earnings per share: Weighted average common shares outstanding 25,641 25,812 26,825 27,563 26,460 Basic earnings per share $ 0.36 $ 0.42 $ 0.32 $ 0.22 $ 1.31 Diluted earnings per share: Weighted average common shares outstanding 26,068 26,421 27,552 28,036 27,019 Diluted earnings per share $ 0.36 $ 0.41 $ 0.31 $ 0.22 $ 1.28
Earnings per share are computed independently for each of the quarters presented. Therefore, the sum of the quarterly per share data does not equal the total computed for the year due to changes in the weighted average number of common shares outstanding. 2. COMPREHENSIVE INCOME The Company has adopted the Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive Income", which establishes standards for the reporting and display of comprehensive income and its components in general purpose financial statements for the year ended December 31, 1998. The table below sets forth "comprehensive income" as defined by SFAS No. 130 for the three and six month period ended June 30: NOTES TO CONSOLIDATED FINANCIAL STATEMENTS JUNE 30, 1998

3. ACQUISITIONS During the six months ended June 30, 1998, the Company completed certain acquisitions which have been accounted for under the purchase method of accounting and which results of operations have been included in the Company's condensed consolidated financial statements from the respective acquisition dates. If the acquisitions had been made at the beginning of 1998 or 1997, pro forma results of operations would not have differed materially from actual results. Acquisitions made in 1998 were M.E. Hunter, Inc. of Atlanta, Georgia, C & S Directional Boring, Inc. of Purcell, Oklahoma, Office Communications Systems, Inc. of Inglewood, California, Phasecom Systems, Inc. of Toronto, Canada, P&E Electric Company, Inc. of Nashville, Tennessee, Lessard-Nyren Utilities, Inc. of Hugo, Minnesota, Electronic Equipment Analyzers, Inc. of Raleigh, North Carolina, Cotton and Taylor of Las Vegas, Nevada, and Stackhouse, Inc. of Goldsboro, North Carolina, nine telecommunications infrastructure and utility contractors with operations primarily in the western, northern and southeastern United States as well as Canada. Additionally, the Company made three international acquisitions of telecommunications infrastructure contractors: CIDE Engenharia Ltda. of Brazil, Acietel Mexicana, S.A. of Mexico and Artcom Services, Inc. of Puerto Rico. DEBT Debt is comprised of the following (in thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS JUNE 30, 1998 The Company has a $125.0 million revolving credit facility, as amended (the "Credit Facility") from a group of financial institutions led by BankBoston, N.A. maturing on June 9, 2000. The Credit Facility is collateralized by the stock of the Company's principal domestic subsidiaries and a portion of the stock of Sintel, S.A., the Company's Spanish subsidiary ("Sintel"). In 1998, the Credit Facility was amended to adjust certain of the financial covenants. Additionally, the Company has several credit facilities denominated in Spanish Pesetas. At June 30, 1998 and December 31, 1997, the Company had $45.3 million (7.0 billion Pesetas) and $50.6 million (7.7 billion Pesetas), respectively, of debt denominated in Pesetas, including $22.1 million and $22.3 million, respectively, remaining under the acquisition debt incurred to acquire Sintel. The Company has paid a portion of the December 31, 1997 installment of the acquisition debt, with the remaining amount to be paid pending resolution of the offsetting amounts between the Company and Telefonica, S.A. ("Telefonica"), the previous owner. On January 30, 1998, the Company sold $200.0 million, 7.75% senior subordinated notes (the "Notes") due in 2008 with interest due semi-annually. The Credit Facility and Notes contain certain covenants that, among other things, restrict the payment of dividends and limit the Company's ability to incur additional debt, create liens, dispose of assets, merge or consolidate with another entity or make other investments or acquisitions. These covenants also require the Company to maintain minimum amounts of stockholders' equity and to meet certain financial ratio coverages, among others, minimum ratios at the end of each fiscal quarter of debt to earnings and earnings to interest expense. 5. OPERATIONS BY GEOGRAPHIC AREAS The Company's principal source of revenue is the provision of telecommunications infrastructure construction services in North America, Spain and the Caribbean and Latin American region (CALA), primarily Brazil. Significant CALA operations commenced on August 1, 1997 with the acquisition of MasTec Inepar.
As of June 30, 1998 1997 ------------------------- Revenue North America $ 275,476 $ 160,434 Spain 91,820 111,208 CALA 64,905 0 ------- ------- Total $ 432,201 $ 271,642 ======= ======= Operating income (loss) North America (1) $ 10,466 $ 22,021 Spain (2) (9,265) 11,088 CALA 5,211 0 ------- ------- Total $ 6,412 $ 33,109 ======= ======= Identifiable assets North America $ 377,112 $ 128,177 Spain 129,242 168,911 CALA 90,655 0 Corporate 224,613 144,154 ------- ------- Total $ 821,622 $ 441,242 ======= =======
(1) North American operations were impacted by several factors including special charges of $4.0 million in the first quarter of 1998. (2) Operating loss in 1998 is due to severance charges totaling $13.4 million recorded in the first quarter of 1998. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS JUNE 30, 1998 There are no material transfers between geographic areas. Operating income consists of revenue less operating expenses, and does not include interest expense, interest and other income, equity in earnings of unconsolidated companies, minority interest and income taxes. Domestic operating income is net of corporate general and administrative expenses. Identifiable assets of geographic areas are those assets used in the Company's operations in each area. Corporate assets include cash and cash equivalents, investments in unconsolidated companies, real estate held for sale, notes receivable and goodwill of $128.6 million which is included in other assets. The Company expects to broaden its segment disclosure to provide additional information on product lines pursuant to FASB Statement No. 131 Disclosures about Segments of an Enterprise and Related Information. 6. SIGNIFICANT CUSTOMERS AND CONCENTRATION OF CREDIT RISK The Company derives a substantial portion of its revenue from the provision of telecommunications infrastructure services to Telefonica, BellSouth Telecommunications Corp. ("BellSouth") and the operating companies of Telecomunicacoes Brasileiras S.A. ("Telebras"). For the six months ended June 30, 1998, approximately 18%, 8% and 15% of the Company's revenue was derived from services performed for Telefonica, BellSouth and Telebras, respectively. During the six months ended June 30, 1997, the Company derived 33% and 11% of its revenue from Telefonica and BellSouth. Although the Company's strategic plan envisions diversification of its customer base, the Company anticipates that it will continue to derive a significant portion of its revenue in the future from these customers. 7. COMMITMENTS AND CONTINGENCIES In December 1990, Albert H. Kahn, a stockholder of the Company, filed a purported class action and derivative suit in Delaware state court against the Company, the then-members of its Board of Directors, and National Beverage Corporation ("NBC"), the Company's then-largest stockholder. The complaint alleges, among other things, that the Company's Board of Directors and NBC breached their respective fiduciary duties in approving certain transactions. In November 1993, Mr. Kahn filed a class action and derivative complaint against the Company, the then members of its Board of Directors, and Jorge L. Mas, Jorge Mas and Juan Carlos Mas, the principal shareholders of the Company. The 1993 lawsuit alleges, among other things, that the Company's Board of Directors and NBC breached their respective fiduciary duties by approving the terms of the acquisition of the Company by the Mas family, and that the Mas family had knowledge of the fiduciary duties owed by NBC and the Company's Board of Directors and knowingly and substantially participated in the breach of these duties. The lawsuit also claims derivatively that each member of the Company's Board of Directors engaged in mismanagement, waste and breach of fiduciary duties in managing the Company's affairs prior to the acquisition by the Mas family. There has been no activity in either of these lawsuits in more than a year. The Company believes that the allegations in each of the lawsuits are without merit and intends to defend these lawsuits vigorously. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS JUNE 30, 1998 In November 1997, Church & Tower, Inc. a subsidiary of the Company ("Church and Tower") filed a lawsuit against Miami-Dade County (the "County") in Florida state court alleging breach of contract and seeking damages exceeding $3.0 million in connection with the County's refusal to pay amounts due to Church & Tower under a multi-year agreement to perform road restoration work for the Miami-Dade Water and Sewer Department ("MWSD"), a department of the County, and the County's wrongful termination of the agreement. The County has refused to pay amounts due to Church & Tower under the agreement until alleged overpayments under the agreement have been resolved, and has counterclaimed against the Company seeking damages that the Company believes will not exceed $2.1 million. The County also has refused to award a new road restoration agreement for MWSD to Church & Tower, which was the low bidder for the new agreement. The Company believes that any amounts due to the County under the existing agreement are not material and may be recoverable in whole or in part from Church & Tower subcontractors who actually performed the work and whose bills were submitted directly to the County. The Company is a party to other pending legal proceedings arising in the normal course of business, none of which the Company believes is material to the Company's financial position or results of operations. The Company, from time to time, may provide customer financing in connection with the provision of its services. As of June 30, 1998, the Company had entered into one such financing agreement to provide up to $50 million of financing to one customer. As of June 30, 1998, the Company had $7.5 million outstanding under this agreement. Additionally, the Company has commitments to purchase approximately $27.0 million of telecommunications equipment over a three year period for a PCS wireless network in Paraguay. ITEM 2 MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION Certain statements in this Quarterly Report are forward-looking, such as statements regarding the Company's future growth and profitability. These forward looking statements are based on the Company 's current expectations and are subject to a number of risks and uncertainties that could cause actual results in the future to significantly differ from results expressed or implied in any forward-looking statements included in this Quarterly Report. These risks and uncertainties include, but are not limited to, the Company's relationship with key customers, implementation of the Company's growth strategy, and seasonality. These and other risks are detailed in this Quarterly Report and in other documents filed by the Company with the Securities and Exchange Commission. Overview MasTec is one of the world's largest contractors specializing in the build-out of telecommunications and other utilities infrastructure. The Company's business consists of the design, installation and maintenance of the outside physical plant for telephone and cable television communications systems and of integrated voice, data and video local and wide area networks inside buildings, and the installation of central office telecommunications equipment. The Company also provides infrastructure construction services to the electric power industry and other public utilities. During the six months ended June 30, 1998, the Company's North American operations were affected by a number of factors including severe weather conditions experienced during the first quarter of 1998, among other things, and performance issues in two divisions related to pricing on a certain contracts some of which are currently being negotiated. In March 1998, Sintel entered into an agreement with its unions to resolve its pending labor dispute. As a result of the agreement reached, the Company recorded a severance charge related to operational personnel and administrative personnel of $1.9 million and $11.5 million, respectively. The total charge of $13.4 million negatively impacted the Company's operating margins in the first quarter of 1998. While management anticipates a reduction in ongoing operating costs to result from these measures, the Company recognizes that it services an increasingly competitive telephony industry in the Spanish market and a substantial portion of any savings may be offset by more competitive prices to Telefonica and other customers. As of June 30, 1998, the Company had terminated 131 workers at a cost of $6.9 million. In July 1998, the Brazilian government privatized its wireline and wireless telephone companies. As a result of the privatization, the Company anticipates that it will increase its sales in the CALA region. However, global deregulation and consolidation within the telecommunications industry may delay or depress capital spending among telecommunications providers as they assess their new business plans and strategies and focus on administrative and operational issues associated with their acquisitions or alliances. Results of Operations Revenue is generated primarily from telecommunications and other utilities infrastructure services. Infrastructure services are provided to telephone companies, public utilities, cable television operators, other telecommunications providers, governmental agencies and private businesses. Costs of revenue includes subcontractor costs and expenses, materials not supplied by the customer, fuel, equipment rental, insurance, operations payroll and employee benefits. General and administrative expenses include management salaries and benefits, rent, travel, telephone and utilities, professional fees and clerical and administrative overhead. The following table sets forth certain supplemental information by geographic region for the three and six months ended June 30, 1998 (in thousands unless otherwise indicated):

Three Months Ended June 30, 1998 compared to Three Months Ended June 30, 1997 The following table sets forth certain historical consolidated financial data as a percentage of revenue for the three months ended June 30, 1998 and 1997.
1998 1997 ---- ---- Revenue 100.0% 100.0% Costs of revenue 75.7% 72.0% Depreciation and amortization 4.4% 3.2% General and administrative expenses 11.8% 12.4% Operating margin 8.1% 12.4% Interest expense 2.9% 1.8% Interest and dividend income and other income, net, equity in unconsolidated companies and minority interest 1.1% 1.0% Income from operations before provision for income taxes 6.3% 11.6% Provision for income taxes 2.5% 3.9% Net income 3.8% 7.7%
Revenue increased $104.6 or 73.9% to $246.1 million in 1998 as compared to $141.5 million in 1997. Revenue from North American operations increased $79.1 million, or 92%, to $165.1 million in 1998 as compared to $86.0 million in 1997. North American revenue growth was primarily generated by acquisitions completed in the latter part of 1997 and during 1998. Revenue generated by international operations increased $25.5 million, or 46%, to $81 million in 1998 as compared to $55.5 million in 1997 due primarily to the inclusion of the Company's Brazilian operations, which contributed $33.8 million to 1998 results. In Spanish Pesetas, revenue declined 13.1% as a result of less spending by Telefonica in Spain during the quarter as it has shifted its investment priority to Latin America, specifically, Brazil. As a result of the reduced spending by Telefonica in Spain, the Company is seeking to diversity its Spanish customer base. Gross profit (revenue less cost of revenue), excluding depreciation and amortization, increased $20.2 million, or 50.9%, to $59.9 million, or 24.3% of revenue in 1998 as compared to $39.7 million, or 28.0% of revenue in 1997. North American gross margins (gross profit as a percentage of revenue) decreased to 25.7% in 1998 from 28% in 1997. The decline in gross margins was related to, among other things, pricing on certain contracts, some of which are currently being negotiated. In addition, 1997 results were favorably impacted by certain short-term projects with attractive pricing. International gross margins decreased to 21.6% in 1998 as compared to 28.2% in 1997 primarily due to the increase in labor costs associated with a new labor agreement in Spain. Additionally, the Company's newly formed Brazilian operations reflected lower margins of 15.5% due to the fact that it operates primarily through subcontractors. Depreciation and amortization increased $6.4 million, or 142.2%, to $10.9 million in 1998 from $4.5 million in 1997. The increase in depreciation and amortization was a result of increased amortization associated with acquisitions, as well as increased capital expenditures from the latter part of 1997 through the second quarter of 1998. As a percentage of revenue, depreciation and amortization was 4.4% and 3.2% of revenue for 1998 and 1997, respectively. General and administrative expenses increased $11.3 million, or 64.2%, to $28.9 million, or 11.8% of revenue for 1998 from $17.6 million, or 12.4% of revenue for 1997. The increase in dollar amount is primarily due to North American general and administrative expenses which were $19.2 million, or 11.6% of North American revenue in 1998, compared to $8.3 million, or 9.7% of domestic revenue for 1997. The increase in dollar amount of domestic general and administrative expenses is due primarily to acquisitions, and an increase in the allowance for doubtful accounts of $1.0 million in connection with management's ongoing evaluation of the collectability of its receivables. International general and administrative expenses increased $0.6 million, or 6.5%, to $9.8 million, or 12.1% of international revenue in 1998 from $9.2 million, or 16.6% of international revenue for 1997. General and administrative expenses for the Company's CALA region were approximately $1.8 million. The Company did not operate in this region until August 1997. The Company generated operating income of $20 million or 8.1% of revenue for 1998 compared to $17.6 million or 12.4% of revenue for 1997. Favorably impacting 1997 operating income were short-term projects with attractive pricing and terms as well as higher volume and margins for its Spanish operations during 1997. Interest expense increased $4.5 million or 173.1%, to $7.1 million for 1998 from $2.6 in 1997 primarily due to the Company's $200.0 million bond offering completed in February 1998. Offsetting the increase was lower interest rates on Spanish borrowings. See -"Financial Condition, Liquidity and Capital Resources." Interest income and other income, net equity in unconsolidated companies and minority interest remained basically unchanged in the aggregate when compared to the 1997 period, however interest income increased significantly due to temporary short-term investments offset by an increase in minority interest attributable to the Company's Brazilian operations. Provision for income taxes was $6.1 million, or 38.0% of income from continuing operations before equity in earnings of unconsolidated companies, taxes and minority interests in 1998, compared to a provision of $5.6 million, or 35.1% of income from continuing operations before equity in earnings of unconsolidated companies, taxes and minority interests in 1997. The increase in the effective tax rate was primarily due to 58% of pre-tax earnings for 1998 having been derived from North American operations, which are subject to a higher effective tax rate. Six Months Ended June 30, 1998 compared to Six Months Ended June 30, 1997
The following table sets forth certain historical consolidated financial data as a percentage of revenue for the six months ended June 30, 1998 and 1997. 1998 1997 ---- ---- Revenue 100.0% 100.0% Costs of revenue 78.5% 71.8% Depreciation and amortization 4.4% 3.1% General and administrative expenses 15.6% 13.0% Operating margin 1.5% 12.1% Interest expense 2.8% 2.0% Interest and dividend income and other income, net, equity in unconsolidated companies and minority interest 0.9% 1.1% (Loss) income from operations before provision for income taxes (0.4)% 11.2% Provision for income taxes 0.2% 3.8% Net (loss) income (0.6)% 7.4%
Revenue increased $160.6 million, or 59.1%, to $432.2 million in 1998 as compared to $271.6 million in 1997. North American revenue increased $115.1 million, or 71.8% from $160.4 million to $275.5 million. The increase in North American revenue was primarily generated by acquisitions completed in the latter part of 1997 and 1998. Revenue generated by international operations increased $45.5 million, or 40.9%, to $156.7 million in 1998 as compared to $111.2 million in 1997 due primarily to the inclusion of the Company's Brazilian operations which contributed $63.5 million to 1998 results. The Company's Spanish revenue was negatively impacted in 1998 by a reduction in the volume of work by its major customer, Telefonica whose investment focus has shifted to Latin America, specifically Brazil. As a result of the reduced spending by Telefonica in Spain, the Company is seeking to diversify its Spanish customer base. Gross profit (revenue less cost of revenue), excluding depreciation and amortization, increased $16.4 million, or 21.4%, to $93 million, or 21.5% of revenue in 1998 as compared to $76.6 million, or 28.2% of revenue in 1997. The decrease in gross profit as a percentage of revenue was due primarily to lower productivity due to severe weather conditions experienced in the first quarter of 1998 by the Company's North American operations. North American gross margins (gross profit as a percentage of revenue) decreased to 22.7% in 1998 from 28.0% in 1997 and the completion of certain higher margin domestic jobs during 1997. The decline in gross margins was related to, among other things, pricing on certain contracts, some of which are currently being negotiated. In addition, 1997 results were favorably impacted by certain short-term projects with attractive pricing. International gross margins decreased to 19.4% in 1998 as compared to 28.5% in 1997 primarily due to the increase in labor costs associated with its new labor agreement in Spain and a $1.9 million charge for severance for direct labor personnel. Additionally, the Company's newly formed Brazilian operations have lower margins of 15.7% due to the fact that it operates primarily through subcontractors. Depreciation and amortization increased $10.9 million, or 131.3%, to $19.2 million in 1998 from $8.3 million in 1997. The increase in depreciation and amortization was a result of increased capital expenditures in the latter part of 1997 and the first quarter of 1998, as well as depreciation and amortization associated with acquisitions. As a percentage of revenue, depreciation and amortization was 4.4% and 3.1% of revenue for 1998 and 1997, respectively. General and administrative expenses increased $32.2 million, or 91.5%, to $67.4 million, or 15.6% of revenue for 1998 from $35.2 million, or 13.0% of revenue for 1997. The increase is primarily due to North American general and administrative expenses which were $35.1 million, or 12.8% of domestic revenue in 1998, compared to $16.0 million, or 10.0% of domestic revenue for 1997. The increase in dollar amount of domestic general and administrative expenses is due primarily to acquisitions. International general and administrative expenses increased $13.1 million, or 68.2%, to $32.3 million, or 20.6% of international revenue in 1998 from $19.2 million, or 17.2% of international revenue for 1997. The increase in Spain's general and administrative expenses was primarily due to severance charges of $12.9 million associated with the agreement reached with the union to reduce administrative personnel in excess of 200 people. General and administrative expenses for the Company's CALA region were approximately $4.2 million. The Company did not operate in this region until August 1997. The Company generated operating income of $6.4 million or 1.5% of revenue for 1998 compared to $33.1 million or 12.1% of revenue for 1997. Favorably impacting 1997 operating income were short-term projects with attractive pricing and terms. Interest expense increased $6.6 million or 120%, to $12.1 million for 1998 from $5.5 in 1997 primarily due to the Company's $200.0 million bond offering completed in February 1998. See - "Financial Condition, Liquidity and Capital Resources." Interest income and other income, net equity in unconsolidated companies and minority interest remained basically unchanged in the aggregate when compared to the 1997 period, however, interest income increased significantly due to temporary short-term investments offset by an increase in minority interest attributable to the Company's Brazilian operations. Financial Condition, Liquidity and Capital Resources The Company's primary liquidity needs are for working capital, to finance acquisitions and capital expenditures and to service the Company's indebtedness. The Company's primary sources of liquidity have been cash flow from operations, borrowings under revolving lines of credit and the proceeds from the sale of investments and non-core assets. Net cash provided by operating activities for the 1998 period was $13.2 million, compared to $29.8 million in the 1997 period. This decrease was due to a breakeven result in the first quarter of 1998 absent charges previously discussed and fluctuations in working capital, particularly increases in accounts receivable and unbilled revenue from Brazilian and North American operations. The Company invested cash, net of cash acquired, in acquisitions and investments in unconsolidated companies totaling $65.3 million during 1998 compared to $15.3 million in 1997. During 1998, the Company made capital expenditures of $32.7 million, primarily for machinery and equipment used in the production of revenue, compared to $8.2 million in 1997. As of June 30, 1998, working capital totaled $180.4 million, compared to working capital of $124.1 million at December 31, 1997. Included in working capital at June 30, 1998 were temporary investments of approximately $20.0 million. The Company continues to pursue a strategy of growth through acquisitions and internal expansion. During 1998, the Company completed 12 acquisitions for $66.3 million in cash and seller financing of $8.6 million. Additionally, the Company believes that there are significant business opportunities available to it that may require the Company to provide customer financing in connection with the sale of its services. As of June 30, 1998, the Company had entered into one such financing agreement to provide up to $50 million of financing to one customer. As of June 30, 1998, the Company had $7.5 million outstanding under this agreement. The Company anticipates customer financing will increase in the future. Additionally, the Company has commitments to purchase approximately $27.0 million over a 3 year period of telecommunications equipment for a PCS wireless network in Paraguay. The Company believes that cash generated from operations, borrowings under its Credit Facility and proceeds from the sale of investments and non-core assets will be sufficient to finance these payments, as well as the Company's working capital needs, capital expenditures and debt service obligations for the foreseeable future. Future acquisitions and internal growth are expected to be financed from these sources, as well as other external financing sources, to the extent necessary, including the additional borrowings. The Company announced a stock repurchase program in April 1998. Through July 24, 1998, the Company has purchased a total of 496,700 shares with an average price of $21.54. The Company may continue to purchase shares from time to time. The Credit Facility restricts the amount of shares that the Company may repurchase up to an additional $3.3 million. In February 1998, the Company issued $200.0 million principal amount of 7.75% Senior Subordinated Notes (the "Notes") due 2008 with interest due semi-annually. The Credit Facility and the Notes contain certain covenants which, among other things, restrict the payment of dividends and limit the Company's ability to incur additional debt, create liens, dispose of assets, merge or consolidate with another entity or make other investments or acquisitions. These covenants also require the Company to maintain minimum amounts of shareholders' equity and to meet certain financial ratio coverages, among others, minimum ratios at the end of each fiscal quarter of debt to earnings and earnings to interest expense. See Note 4 of Notes to Consolidated Financial Statements. The Company conducts business in several foreign currencies that are subject to fluctuations in the exchange rate relative to the U.S. dollar. The Company does not enter into foreign exchange contracts. It is the Company's intent to utilize foreign earnings in the foreign operations for an indefinite period of time. In addition, the Company's results of operations from foreign activities are translated into U.S. dollars at the average prevailing rates of exchange during the period reported, which average rates may differ from the actual rates of exchange in effect at the time of the actual conversion into U.S. dollars. The Company's current and future operations and investments in certain foreign countries are generally subject to the risks of political, economic or social instability, including the possibility of expropriation, confiscatory taxation, hyper-inflation or other adverse regulatory or legislative developments, or limitations on the repatriation of investment income, capital and other assets. The Company cannot predict whether any of such factors will occur in the future or the extent to which such factors would have a material adverse effect on the Company's international operations. Year 2000 The Company has been assessing the impact that the Year 2000 issue will have on its computer systems, including both hardware and software. The Company has also initiated formal communications with all of its significant suppliers and large customers to determine the extent to which the Company's interface systems are vulnerable to those third parties' failures to remediate their own Year 2000 issue. Assuming that remediation projects can be implemented as planned, the Company believes future costs relating to the Year 2000 issue, which will be expensed as incurred, will not have a material adverse impact on the Company's business, operations or financial condition.
