Income Tax [Abstract]
Income Tax	Note 9 – Income Tax The provision for income taxes is different from the amount determined by applying the U.S. federal statutory rate to consolidated income before taxes. The differences are attributable to earnings considered indefinitely reinvested in foreign operations, change in valuation allowance, state taxes, unrecognized tax benefits, and foreign withholding tax on interest. Our effective tax rate was 31.8% and 19.2% for the nine months ended September 30, 2016 and 2015, respectively. The rate difference was primarily caused by the Company's determination during the second quarter of 2015 that earnings of Australian subsidiaries are indefinitely invested in foreign operations.

Note 9 – Income Tax

The provision for income taxes is different from the amount determined by applying the U.S. federal statutory rate to consolidated income before taxes. The differences are attributable to earnings considered indefinitely reinvested in foreign operations, change in valuation allowance, state taxes, unrecognized tax benefits, and foreign withholding tax on interest. Our effective tax rate was 31.8% and 19.2% for the nine months ended September 30, 2016 and 2015, respectively. The rate difference was primarily caused by the Company's determination during the second quarter of 2015 that earnings of Australian subsidiaries are indefinitely invested in foreign operations.
