2.Income Taxes

Income taxes for the interim periods are computed using the effective tax rates estimated to be applicable for the full fiscal year, as adjusted for any discrete taxable events that occur during the period.

The Company files income tax returns in the United States ("U.S.") on a federal basis and in many U.S. state and foreign jurisdictions. Certain tax years remain open to examination by the major taxing jurisdictions to which the Company is subject. The Company does not anticipate that its total unrecognized tax benefits or obligations will significantly change due to the settlement of examinations or the expiration of statutes of limitation during the next twelve months.
