Income Tax Disclosure [Abstract]
Income Taxes	Note 5 – Income Taxes Our estimated annual tax rate for 2017 is expected to be 42%. 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 estimated annual tax rate for 2016 was expected to be 28% in the first quarter. This was lower than the U.S. statutory rate of 34% primarily due to income in foreign jurisdictions taxed at lower rates partially offset by valuation allowances on taxable losses. Discrete items related to a measurement period adjustment and changes to tax rates on deferred tax liabilities increased the first quarter effective rate to 39%. 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.
