3. Income Taxes

Income tax expense for the six months ended June 30, 2016 and 2015 has been computed using estimated annual effective tax rates. These rates are revised, if necessary, at the end of each successive interim period to reflect current estimates of the annual effective tax rates.

For the six months ended June 30, 2016, the tax provision is comprised of a $3.9 million U.S. federal income tax expense and a $17.1 million foreign income tax expense. For the six months ended June 30, 2015, the tax provision was comprised of a $37.4 million U.S. federal income tax expense and a $16.4 million foreign income tax expense.

Although most of the Company’s non–U.S. income is subject to U.S. federal income tax, certain of its non–U.S. income is not subject to U.S. federal income tax until repatriated. Foreign taxes on this non–U.S. income are accrued at the local foreign tax rate, as opposed to the higher U.S. statutory rate, since these earnings currently are expected to be indefinitely reinvested overseas. This assumption could change as a result of a sale of the subsidiaries, the receipt of dividends from the subsidiaries, a change in management’s intentions, or as a result of various other events. The Company has not made a provision for U.S. taxes on $10.6 million and $63.0 million of non-U.S. income for the six months ended June 30, 2016 and 2015, respectively. However, in the future, if such earnings were distributed to the Company, taxes of $49.1 million would be payable on the accumulated undistributed earnings and would be reflected in the tax provision for the year in which these earnings are no longer intended to be indefinitely reinvested overseas, assuming all foreign tax credits are realized.

The Company or its subsidiaries files income tax returns in the U.S. federal jurisdiction and various state jurisdictions, as well as foreign jurisdictions. The Company and its subsidiaries are subject to U.S. federal income tax examinations by tax authorities for years after 2011, U.S. state income tax examinations for years after 2011 and foreign examinations for years after 2011.
