DOCUMENTS INCORPORATED BY REFERENCE Parts of Form 10-K into which Document Document is incorporated - -------- ------------------------ Portions of the Annual Report to Shareholders for the year ended December 31, 1997 II and IV Portions of the Proxy Statement to be distributed in connection with the 1998 Annual Meeting of Shareholders III 2 PART I CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR" PROVISIONS OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995. The statements contained in this Annual Report on Form 10-K, specifically those contained in Item 1 "Business" and Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operation," and statements incorporated by reference into this Form 10-K from the 1997 Annual Report to Shareholders, along with statements in other reports filed with the Securities and Exchange Commission, external documents and oral presentations, which are not historical are "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements represent Tollgrade Communications, Inc.'s (the "Company") present expectations or beliefs concerning future events. The Company cautions that such statements are qualified by important factors that could cause actual results to differ materially from those in the forward-looking statements. Results actually achieved may differ materially from expected results included in these statements. Those factors which specifically related to the Company's business include the following: rapid technological change along with the need to continually develop new products; dependence on a single product line; competition; dependence on key employees; management of Company's growth; dependence on certain customers; dependence on certain suppliers; proprietary rights and risks of third party claims of infringement; and government regulation. ITEM 1. BUSINESS. The Company was incorporated in Pennsylvania in 1986 and began operations in 1988. Its principal offices are located at 493 Nixon Road, Cheswick, Pennsylvania 15024 and its telephone number is (724) 274-2156. The Company designs, engineers, markets and supports proprietary products which enable telephone companies to use their existing line test systems to remotely diagnose problems in "plain old telephone service" ("POTS") lines containing both copper and fiber optics. POTS lines comprise the vast majority of lines in service today throughout the world. In addition to traditional voice service, POTS includes lines for popular devices such as computer modems and fax machines. POTS excludes the more complex lines, such as data communications service lines, commonly referred to as "special services." POTS line test systems, located at telephone companies' central offices, diagnose problems in the "local loop", which is the portion of the telephone network which connects end users to a telephone company's central office, and is comprised primarily of copper wireline. The ability to remotely test reduces the time needed to identify and resolve problems and eliminates or reduces the cost of dispatching a technician to the problem site. Most POTS line test systems were designed for use over copper wireline only, so that the introduction of fiber-optic technology into the local loop renders it inaccessible to these test systems. The Company's metallic channel unit ("MCU(R)") products solve this problem by extending test-system access through the fiber-optic portion into the copper portion of the local loop. Products. The Company's MCU products plug into the digital loop carrier ("DLC") systems that are large systems manufactured by equipment vendors such as AT&T, that are used by telephone companies to link the copper and fiber-optic portions of the local loop. DLC systems are located at the telephone company central offices and at remote sites within a local user area, and effectively multiplex the services of the copper lines into a single fiber-optic line. In many instances, several DLC systems are located at a single remote site to serve several thousand different end-user homes and offices. Generally, for every DLC remote site, two MCU line testing products are deployed. To ensure compatibility with these DLC systems, the Company pays royalties pursuant to license agreements for the use of proprietary design integrated circuits ("PDICs"). The PDICs are the design and property of the DLC system manufacturer from which they are purchased. The Company maintains license agreements with and pays royalties to 2 3 Lucent Technologies, Fujitsu Network Transmission Systems, Inc., NEC American, Inc. and Reliance Comm/Tec Corporation. In general, the current terms for expiration of these agreements range at various times between August 1998 and an indefinite duration, with renewal provisions (unless earlier terminated) for periods of between one and five years. In addition, certain of these agreements can be terminated prior to renewal. The Company incurred $1,075,800, $1,893,000 and $2,014,000, respectively in 1995, 1996 and 1997 as royalties under the license agreements, which royalties are calculated either based on a percentage of the list price of MCU products or a fixed amount per unit which incorporate the technology licensed under each such agreement.Certain of the license agreements require the Company to maintain the confidentiality of the licensor's proprietary information and/or the terms and conditions of the agreement itself. In addition, the Company maintains license agreements which do not contain royalty provisions with Advanced Fibre Communications, DSC Technologies Corporation, Northern Telecom Inc., UTSTARCOM, Inc., and most recently entered into license agreements with Next Level Communications and SAT Division Reseaux et Telecommunications (a French Corporation) for which products are still in the early phase of development. The expiration dates of these agreements range at various times between July 1998 and November 2004, with renewal provisions (unless earlier terminated) for periods of one or more years. Future license agreements entered into by the Company may contain terms comparable to, or materially different than, the terms of existing agreements as competitive and other conditions warrant. The loss of PDICs license agreements or the inability of the Company to maintain an adequate supply of PDICs could have a material adverse effect on the Company's business. Other MCU technology is also used with home and business alarm systems. As with home service line testing, home alarm systems must be monitored from the alarm company's headquarters along a hybrid copper and fiber-optic line. The Company's alarm-related MCU products are used to facilitate the transport of analog alarm signals from subscriber homes to alarm company monitoring stations across the hybrid telephone network. These units plug into equipment at both central office and remote locations. MCU products accounted for more than 93%, 93% and 94% of the Company's sales in 1995, 1996 and 1997, respectively. In addition, the Company has recently entered into a license agreement with C-Cor Electronics, Inc. (a cable television systems developer) in which the Company will develop and subsequently provide its status monitoring transponder technology that will be incorporated into C-Cor's cable network management system. Product and Technology Development. The Company's product development personnel are organized into teams, each of which is effectively dedicated to a specific product line(s) or technology. Each product team also implements the Company's ongoing "value engineering" programs which are designed to replace the Company's products with successive generations having additional features and/or lower costs. The Company continuously monitors developing technologies and introduces products as defined standards and markets emerge. In addition, the Company continues to investigate the development of new applications for its MCU technology and other technologies to service the telecommunications industry. During 1995, 1996 and 1997, research and development expenses were approximately $2,637,000, $3,921,000 and $5,945,000, respectively. Proprietary Rights. The names "Tollgrade(R)", "MCU(R)" and "Micro-Bank(R)", and the Company's corporate logo are registered trademarks of the Company. "Team TollgradeSM" is a service mark of the Company and "Lighthouse(TM)", "Digitest(TM)" and "Telaccord(TM)" are trademarks for which registration has been applied. The Company has obtained three patents on the MCU products with expiration dates ranging from 2010 to the year 2014. In addition, the Company has five U.S. provisional and two international patent cooperation treaty ("PCT") patent applications pending. The Company will seek additional patents from time to time related to its research and development activities. The Company protects its trademarks, patents, inventions, trade secrets, and other proprietary rights by contract, trademark, copyright and patent registration, and internal security. 3 4 Customers. The Company's primary customers are the five regional Bell operating companies ("RBOCs"), which are Ameritech Corporation, Bell Atlantic Corporation, BellSouth Corporation, SBC Communications Inc., and US WEST Inc., as well as major independent telephone companies such as Sprint and Southern New England Telephone Company. Historically, almost all of the Company's sales have been made to the RBOCs (86% in 1997). Bell Atlantic Corporation and BellSouth Corporation accounted for 30% and 24%, respectively, of the Company's total sales in 1997. The Company's relationships with its customers are material to the Company's business, and the loss of any such relationship could have a material adverse effect on the Company's business. Manufacturing. The Company's manufacturing operations consist primarily of quality control, functional testing, final assembly, burn-in and shipping. During 1997, the Company received ISO 9001 registration from British Standards Institution, Inc. ISO 9000 is a harmonized set of standards that define quality assurance management. Written by the International Organization for Standardization ("ISO"), it is recognized throughout the United States, Canada, the European Union and Japan. To be registered, the Company developed and maintains internal documentation and processes to support the production of quality products to ensure customer satisfaction. For a portion of 1997 and prior years, the Company utilized one key independent subcontractor to perform a majority of the circuit board assembly and in-circuit testing work on its products. The Company also utilized other subassembly contractors on a more limited basis. During the third quarter, 1997, the key subcontractor notified the Company that its services would be phased out, at the latest, during early 1998. The Company is in the process of phasing out the use of that subcontractor, and is now utilizing two other subassembly subcontractors that had been utilized by the Company on a more limited basis in the past. The loss of the subcontractors could cause delays in the Company's ability to meet production obligations and could have a material adverse effect on the Company's results of operations. In addition, shortages of raw material to, or production capacity constraints at, the Company's subcontractors could negatively affect the Company's ability to meet its production obligations and result in increased prices for affected parts. Any such reduction may result in delays in shipments of the Company's products or increases in the price of components, either of which could have a material adverse impact on the Company. The Company currently procures all of its components from outside suppliers. Generally, the Company uses industry standard components for its products. Application specific integrated circuits ("ASICs") are a key component to the manufacturing process and are custom made to the Company's specifications. Although the Company has generally been able to obtain ASICs on a timely basis, a delay in the delivery of these components could have a material adverse impact on the Company. Backlog. The Company's backlog at December 31, 1997 was approximately $1.6 million, as compared to approximately $0.9 million at December 31, 1996. The increase was due largely to the receipt of certain orders under Original Equipment Manufacturer ("OEM") arrangements scheduled for shipment in the first quarter of 1998 and beyond. The Company includes in backlog all firm purchase orders for products regardless of their ship date. Because of the quick turnaround that the customers expect on their orders, which is sometimes one to two weeks, and because of the possibility of customer changes in delivery schedules or cancellation of orders, the Company's backlog as of any particular date may not be indicative of actual revenues expected for any future period. Competitive Conditions. The deciding competitive factors in the Company's market include price, product features, performance, reliability, service and support, breadth of product line, technical documentation and prompt delivery. The Company believes that it competes favorably on all of these factors, and certain of its products have proprietary or patented features. The Company also attempts to enter into development agreements for its MCU products with the manufacturers of DLC and other complex systems, which serves to ensure compatibility for its products. Competition would increase if new companies enter the Company's product markets or existing competitors expand their product lines. For instance, the recently enacted telecommunications reform legislation has lifted the restrictions which previously prevented the RBOCs from manufacturing telecommunications equipment. Pursuant to this legislative reform, the RBOCs, which are the Company's largest customers, may become competitors of the 4 5 Company in the markets served by the Company. For the Company's line-testing MCU devices, the primary competitive products are the remote monitoring units made by Teradyne, Inc. and the Harris Dracon division of Harris Corporation. The Company's MCU is simpler and less costly to install and permits the full complement of centralized testing to be performed as quickly and accurately as with copper by-pass wiring. The Company believes that Wiltron Company, Inc. and the Tau-Tron division of General Signal Corporation, providers of special services test systems, could expand into POTS line testing. The alarm-related MCU product's primary competitor is the Turbo 2000 unit made by Antec Corporation. Employees. At December 31, 1997 the Company had 205 full-time employees, all in the United States. None of the Company's employees is represented by a collective bargaining agreement. Government Regulation. The telecommunications industry is subject to regulation in the United States and other countries. Federal and state regulatory agencies, including the FCC and various state public utility commissions and public service commissions, regulate most of the Company's domestic customers. While such regulation does not typically affect the Company directly, the effects of such regulations on the Company's customers may, in turn, adversely impact the Company's business and operating results. Governmental authorities also have promulgated regulations which, among other things, set installation and equipment standards for private telecommunications systems and require that all newly installed hardware be registered and meet certain government standards. ITEM 2. PROPERTIES. The Company's headquarters and principal administrative, engineering and assembly facilities are located in Cheswick, Pennsylvania and occupy approximately 67,000 square feet. The Company occupies its current facilities under a lease that expires in December, 1998 with successive options to renew through 2010. The Company believes that its current facilities are adequate to support its present level of operations and there is ample room to support continued sales growth for the foreseeable future. ITEM 3. LEGAL PROCEEDINGS. There are currently no outstanding or pending material legal proceedings with respect to the Company or its business. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. During the fourth quarter of 1997, there were no matters submitted to a vote of security holders through solicitation of proxies or otherwise. 5 6 EXECUTIVE OFFICERS OF THE COMPANY Information relating to the executive officers of the Company as of January 31, 1998 is set forth below: R.
