The Company regularly evaluates estimates and assumptions related to the deferred income tax asset valuations and share-based compensation. The Company bases its estimates and assumptions on current facts, historical experience and various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the other sources. The actual results experienced by the Company may differ materially and adversely from the Company’s estimates.
