These estimates are based on management's best knowledge of current events and actions the Company may undertake in the future. Significant estimates are used in accounting for, among other items, long-lived assets and income taxes. Actual results may ultimately differ from estimates, although management does not generally believe such differences would materially affect the financial statements in any individual year.</span></div>
