Forward-Looking Statements Certain statements the company made or incorporated by reference in this release, or made in other documents furnished to or filed with the Securities Exchange Commission, as well as in press releases or in oral presentations made by company employees, reflect management's estimates and beliefs and are intended to be "forward-looking statements" identified in the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Words such as "expects," "anticipates," "believes," "intends," "plans," "estimates" and other similar references to future periods typically identify forward-looking statements. The company cautions readers that forward-looking statements reflect the company's current beliefs and judgments, but are not guarantees of future performance or outcomes. They are based on a number of assumptions and estimates that are inherently affected by economic, competitive, regulatory, and operational risks, uncertainties and contingencies that are beyond the company's control, and upon assumptions about future business decisions and conditions that may change.

Forward-looking statements are only predictions and involve risks and uncertainties, resulting in the possibility that actual events or performance will differ materially from such predictions as a result of certain risk factors, including reduced selling prices, shipments and profits associated with a highly competitive and cyclical industry; increased global steel production and imports; changes in the cost of raw materials and energy; the company's significant amount of debt and other obligations; severe financial hardship or bankruptcy of one or more of the company's major customers or key suppliers; reduced demand in key product markets due to competition from aluminum or other alternatives to steel; excess inventory of raw materials; supply chain disruptions or poor quality of raw materials; production disruption or reduced production levels; the company's healthcare and pension obligations; not reaching new labor agreements on a timely basis; major litigation, arbitrations, environmental issues and other contingencies; regulatory compliance and changes; climate change and greenhouse gas emission limitations; financial, credit, capital and banking markets; derivative contracts to hedge commodity pricing volatility; potential permanent idling of facilities; inability to fully realize benefits of margin enhancement initiatives; information technology security threats and cybercrime; as well as those risks and uncertainties discussed in more detail in the company's Annual Report on Form 10-K for the year ended December 31, 2015, as updated in subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K filed with or furnished to the Securities and Exchange Commission.

As such, the company cautions readers not to place undue reliance on forward-looking statements, which speak only to the company's plans, assumptions and expectations as of the date hereof. The company undertakes no obligation to publicly update any forward-looking statement, except as required by law.
