Actual results could differ from those estimates. The most significant estimates included in the preparation of the consolidated financial statements are related to asset retirement obligations, income taxes and impairment of long-lived assets. However, the consolidated financial statements contain additional estimates, including, but not limited to, other postretirement benefits, coal workers' pneumoconiosis, workers' compensation, salary retirement benefits, stock-based compensation, contingencies and the values of coal properties.</span></div>
