Level 3 Communications reported its fourth quarter 2016 results in February 2017. The presentation included modified adjustments to prior period results and cautionary statements about forward-looking projections. It noted some statements were based on current expectations and were subject to risks and uncertainties that could cause actual results to differ materially. Important risk factors that could prevent Level 3 from achieving its goals included its ability to increase revenue, develop business support systems, manage network failures, protect its network security, develop new services, and integrate acquisitions. The presentation also provided additional information on the proposed combination of Level 3 and CenturyLink and directed investors to filings with the SEC for more details.
