They include statements regarding our intentions, beliefs or current expectations concerning, among other things, the impact of the actions described in this press release; our results of operations; financial condition; liquidity; prospects, growth and strategies; the expected impact of the COVID-19 pandemic; the timing, structure and expected impact of our operational efficiency and cost-reduction initiatives and the estimated savings and amounts expected to be incurred in connection therewith; and potential business decisions. We derive many of our forward-looking statements from our operating budgets and forecasts, which are based upon many detailed assumptions. We caution that it is very difficult to predict the impact of known factors, and, of course, it is impossible for us to anticipate all factors that could affect our actual results. All forward-looking statements are based upon information available to us on the date of this report.

Important factors that could cause actual results to vary from expectations include, but are not limited to: the duration and severity of the COVID-19 pandemic and its impact on the federal, state and local economies and on K–12 schools; the rate and state of technological change; state requirements related to digital instructional materials; our ability to execute on our long-term growth strategy; increases in our operating costs; management and personnel changes; timing, higher costs and unintended consequences of our operational efficiency and cost-reduction initiatives, including the actions described in this press release; and other factors discussed in our news releases, public statements and/or filings with the U.S. Securities and Exchange Commission, including our most recent Annual and Quarterly Reports on Form 10-K and Form 10-Q. In light of these risks, uncertainties and assumptions, the forward-looking events described herein may not occur.
