Income Taxes [Abstract]
Income Taxes	Note 7 – Income Taxes Our effective tax rate for 2012 is expected to be 21%. This is lower than the U.S. statutory rate primarily due to income in foreign jurisdictions taxed at lower rates. The effective tax rate for 2011 was also 21% in the first quarter. At December 31, 2011, we had $9,907 of U.S. NOL carryforwards, of which $7,334 represents U.S. tax deductions for employee stock option gains, the tax benefit of which will be credited to additional paid in capital when the NOL carryforwards are utilized. The U.S. loss carryforwards expire in varying amounts beginning in 2022 and continuing through 2029. If certain substantial changes in the company's ownership were deemed to have occurred, there would be an annual limitation on the amount of the U.S. NOL carryforwards that could be utilized. At December 31, 2011, we had foreign NOL carryforwards of $5,535 and other foreign deductible carryforwards of $2,770. The foreign NOL carryforwards have no expiration dates and the other deductible carryforwards expire from 2016 to 2018. At December 31, 2011, we had a valuation allowance of $2,088 for certain foreign deferred tax assets.

Our effective tax rate for 2012 is expected to be 21%. This is lower than the U.S. statutory rate primarily due to income in foreign jurisdictions taxed at lower rates. The effective tax rate for 2011 was also 21% in the first quarter.

At December 31, 2011, we had $9,907 of U.S. NOL carryforwards, of which $7,334 represents U.S. tax deductions for employee stock option gains, the tax benefit of which will be credited to additional paid in capital when the NOL carryforwards are utilized. The U.S. loss carryforwards expire in varying amounts beginning in 2022 and continuing through 2029. If certain substantial changes in the company's ownership were deemed to have occurred, there would be an annual limitation on the amount of the U.S. NOL carryforwards that could be utilized.

At December 31, 2011, we had foreign NOL carryforwards of $5,535 and other foreign deductible carryforwards of $2,770. The foreign NOL carryforwards have no expiration dates and the other deductible carryforwards expire from 2016 to 2018. At December 31, 2011, we had a valuation allowance of $2,088 for certain foreign deferred tax assets.
