Liquidity and Capital Resources Historically, the Company has financed its operations, including increases in accounts receivable and capital equipment acquisitions, through cash generated from operations, cash proceeds from its initial public offering of common stock, investment earnings and the sale of the Company’s stock through the exercise of employee stock options and the Employee Stock Purchase Plan. The Company’s operating activities provided cash of $3.5 million and $6.8 million in the six month periods ended March 31, 2001 and 2002, respectively. The cash provided by the Company’s operations for the six months ended March 31, 2002 was attributable to net income and increased deferred revenue and accrued liabilities, partially offset by an increase in accounts receivable that reflected timing of invoicing. Investing activities, consisting of purchases and sales of short-term investments and to a lesser extent additions to property and equipment, provided cash of $10.3 million in the six months ended March 31, 2001 and used cash of $26.9 million in the six months ended March 31, 2002. Cash flows from financing activities in the six months ended March 31, 2001 and 2002 were attributable to exercises of employee stock options and the purchase of shares under the employee stock purchase plan in both periods. As of March 31, 2002, the Company had working capital of $69.1 million, cash and cash equivalents of $24.6 million and short-term investments of $43.8 million. As of March 31, 2002, the Company had no bank indebtedness and no long-term commitments other than operating lease obligations. Minimum annual rental payments under non-cancelable operating leases total $932,000 in the current fiscal year ending September 30, 2002 and decline thereafter. The Company expects that capital expenditures in fiscal 2002 will remain consistent with the $625,000 level in the prior year.* The Company believes that cash and cash equivalents, short-term investments and funds generated from operations will provide the Company with sufficient funds to finance its operations for at least the next 12 months.* The Company may require additional funds to support its working capital requirements or for other purposes. There can be no assurance that additional financing will be available or that, if available, such financing will be obtainable on terms favorable to the Company or its stockholders. Factors That May Affect Future Results Fluctuations in Quarterly Operating Results; Lengthy Sales Cycle The Company’s revenues and operating results are relatively difficult to forecast for a number of reasons, including (i) the variable size and timing of individual purchases by customers, (ii) seasonal factors that may affect capital spending by customers, such as the varying fiscal year ends of customers and the reduction in business during the summer months, particularly in Europe, (iii) the relatively long sales cycles for the Company’s products, (iv) the timing of hiring sales and technical personnel, (v) changes in timing and amount of sales incentive compensation, (vi) competitive conditions in the Company’s markets, (vii) exchange rate fluctuations, (viii) changes in the mix of products sold, (ix) the timing of the introduction and market acceptance of new products or product enhancements by the Company, its customers, competitors or suppliers, (x) costs associated with developing and introducing new pr oducts, (xi) product life cycles, (xii) changes in the level of operating expenses relative to revenues, (xiii) software defects and other product quality problems, (xiv) customer order deferrals in anticipation of new products, (xv) delays in purchasing decisions or customer orders due to customer consolidation, (xvi) supply interruptions, (xvii) changes in the regulatory environment and (xviii) changes in global or regional economic conditions or in the telecommunications industry. The Company’s revenues in any period generally have been, and are likely to continue to be, derived from relatively small numbers of sales and service transactions with relatively high average revenues per order. Therefore, the loss of any orders or delays in closing such transactions could have a more significant impact on the Company’s quarterly revenues and results of operations than on those of companies with relatively high volumes of sales or low revenues per order. See “Dependence on Limited Number of Customers” below. The Company’s products generally are shipped within 15 to 30 days after orders are received and revenues are recognized upon installation of the products, provided no significant vendor obligations remain and collection of the related receivable is deemed probable. As a result, the Company generally does not have a significant backlog of orders, and revenues in any quarter are s ubstantially dependent on orders booked, shipped and installed in that quarter. 14 |
