Income Taxes [Abstract]
Income Taxes	Note 7. Income Taxes We recorded a tax provision of $35,000 on our $2.0 million of income before taxes and equity in net loss of unconsolidated entities for the three months ended March 31, 2013. For the first three months of 2012 our income tax provision was $168,000 on our $8.2 million of income before taxes and equity in net loss of unconsolidated entities. These provision amounts represent tax on our qualifying U.S. flag operations, which continue to be taxed under the "tonnage tax" provisions rather than the normal U.S. corporate income tax provisions, state income taxes paid, and foreign income tax withholdings or refunds. We established a valuation allowance against deferred income tax assets in 2010 because, based on available information, we could not conclude that it was more likely than not that the full amount of deferred income tax assets generated primarily by net operating loss carryforwards and alternative minimum tax credits would be realized through the generation of taxable income in the near future. We have and will continue to evaluate the need for a valuation allowance on an annual basis.

Note 7. Income Taxes

We recorded a tax provision of $35,000 on our $2.0 million of income before taxes and equity in net loss of unconsolidated entities for the three months ended March 31, 2013. For the first three months of 2012 our income tax provision was $168,000 on our $8.2 million of income before taxes and equity in net loss of unconsolidated entities. These provision amounts represent tax on our qualifying U.S. flag operations, which continue to be taxed under the "tonnage tax" provisions rather than the normal U.S. corporate income tax provisions, state income taxes paid, and foreign income tax withholdings or refunds. We established a valuation allowance against deferred income tax assets in 2010 because, based on available information, we could not conclude that it was more likely than not that the full amount of deferred income tax assets generated primarily by net operating loss carryforwards and alternative minimum tax credits would be realized through the generation of taxable income in the near future. We have and will continue to evaluate the need for a valuation allowance on an annual basis.
