To partially offset substantially lower than anticipated revenues, Iridium is reducing expenses in areas not essential to generating increased revenues. The details of the financial results are shown in the accompanying table. As of March 31, there were approximately 10,294 customers on the Iridium system, including 7,188 satellite-homed voice customers, 1,031 cellular-homed voice customers and 2,075 satellite paging customers. The Company is in the early stages of its transition from development to commercialization stage, and many of the customers included in the current results may be, or may have been during the reporting period, in a mode of evaluation and test of the Iridium services. Furthermore, the Company believes that the reported results reflect that periods as long as several weeks can normally be encountered from the date of customer activation, which these results report, and the actual usage of the services by such customers. Iridium's efforts to attract customers were hindered by a number of factors during the period, notably, limited availability of some handset models and accessories in many markets, and delays by the overall Iridium distribution network to field sufficient numbers of properly trained and equipped salespeople. With the commencement of handset shipments by Kyocera Corporation late in the quarter, and with Motorola now shipping virtually all Iridium accessories, production by the manufacturers is now adequate, although a number of distribution and importation issues continue to constrain actual product availability in many markets. "Although we have succeeded in building a network that is providing high-quality service to our customers, we were very disappointed with our first quarter customer and revenue numbers," said John A. Richardson, Iridium's interim CEO. "Clearly, we have a great deal of work to do to improve our marketing, distribution and sales activities all over the world. Over the course of the first quarter, we have identified major causes for the poor sales 4 performance, and are initiating aggressive actions in response, acting in concert with our regional Gateway partners, our equipment suppliers, and the outstanding roster of service providers and roaming partners they have enlisted." Iridium LLC, its gateway partners, and its equipment suppliers are initiating a number of significant actions to address the sales shortfall, including: tailoring the Iridium product and service offering to better fit the identified market demand, accelerating introduction of Iridium products and services by the types of distribution channel that have proven to be the most effective to date, and reconsideration of product and service prices.
