While the Company is under examination in various tax jurisdictions with respect to certain open years, the Company does not expect that the result of any final determination related to these examinations will have a material impact on its financial statements. Developments with respect to such examinations are monitored on an ongoing basis and adjustments to tax liabilities are made as appropriate.
