Forward-Looking Statement
Some of the statements made by Level 3 in this press release are forward-looking in nature. Actual results may differ materially from those projected in forward-looking statements. Level 3 believes that its primary risk factors include, but are not limited to: increasing the volume of traffic on Level 3’s network; developing new products and services that meet customer demands and generate acceptable margins; successfully completing commercial testing of new technology and information systems to support new products and services, including voice transmission services; stabilizing or reducing the rate of price compression on certain of our communications services; integrating strategic acquisitions; attracting and retaining qualified management and other personnel; ability to meet all of the terms and conditions of our debt obligations; overcoming Software Spectrum’s reliance on financial incentives, volume discounts and marketing funds from software publishers; and reducing downward pressure of Software Spectrum’s margins as a result of the use of volume licensing and maintenance agreements. Additional information concerning these and other important factors can be found within Level 3’s filings with the Securities and Exchange Commission. Statements in this release should be evaluated in light of these important factors.
