Income Taxes	Note 5 – Income Taxes Our estimated annual tax rate for 2017 before discrete items is expected to be 40%. This is higher than the U.S. statutory rate of 34% primarily due to valuation allowances on taxable losses, primarily in Canada, partially offset by income in foreign jurisdictions taxed at lower rates. Our effective tax rate for the third quarter was 48%. The effective rate in the third quarter was impacted by the mix of earnings in various jurisdictions. Our ultimate tax rate will depend on the mix of earnings in various jurisdictions. As of the third quarter of 2016, our estimated annual tax rate for 2016 before discrete items was expected to be 28%. The estimated rate was lower than the U.S. statutory rate primarily due to income in foreign jurisdictions taxed at lower rates, partially offset by valuation allowances on taxable losses. Discrete items related to changes in estimates upon completion of tax filings and a measurement period adjustment increased the full-year 2016 effective rate to 37%. The effective tax rate for the third quarter of 2016 was 61%. At December 31, 2016, we had foreign tax credit carryforwards of $7,027 for future U.S. tax returns. These foreign tax credits expire in 2023 through 2026. We have not provided a valuation reserve for the foreign tax credits as we believe it is more likely than not that they will be realized. At December 31, 2016, we had deferred tax assets of $16,655 resulting from foreign and state NOL carryforwards of $58,110 and other foreign deductible carryforwards of $16,817. At December 31, 2016, we had a valuation allowance of $6,192 against deferred tax assets related to certain carryforwards.
