Management bases its estimates on historical experience and on assumptions that it believes are reasonable. Management assesses these estimates on a regular basis; however, actual results could differ from those estimates. Items subject to such estimates and assumptions include but not limit to the deferral and breakage of revenues; the fair value of unquoted debt and equity securities, the useful lives of property, plant and equipment and right-of-use assets; allowances for doubtful accounts; the valuation of deferred tax assets, long-lived assets, investments and share-based compensation; and accrued pension liabilities (prepaid pension assets), income tax uncertainties and other contingencies. We believe the critical accounting policies listed below affect management’s judgments and estimates used in the preparation of the consolidated financial statements.</span></p>
