Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We utilize our estimated annual effective tax rate to determine our provision for income taxes for interim periods. The income tax provision is computed by taking the estimated annual effective tax rate and multiplying it by the year-to-date pre-tax book income. We recorded income tax expense of $2.8 million and $2.5 million for the three months ended June 30, 2014 and 2013, respectively. Our effective tax rate was 24.7% and 30.0% during the three months ended June 30, 2014 and 2013, respectively. The decrease in our effective tax rate was due to the recording of $0.4 million of additional tax reserves in the second quarter of 2013 resulting from a tax audit in Hong Kong for years preceding our acquisition of Enson Assets Limited. In addition, foreign earnings, which have a lower tax rate than the United States, represented a higher percentage of our pre-tax income during the three months ended June 30, 2014 compared to the same period in 2013. Partially offsetting these favorable items was the expiration of the "Look-Through" rule, which expired as of December 31, 2013 and resulted in an increase of Subpart F income for the three months ended June 30, 2014. In addition, the federal research and development ("R&D") tax credit for 2014 has not been passed; therefore, the benefit is not included in our estimated tax rate for the current year. We recorded income tax expense of $4.1 million and $2.9 million for the six months ended June 30, 2014 and 2013, respectively. Our effective tax rate was 24.5% and 24.9% during the six months ended June 30, 2014 and 2013, respectively.

Accrued interest and penalties of $0.2 million and $0.1 million on June 30, 2014 and December 31, 2013, respectively, are included in our unrecognized tax benefits. We file income tax returns in the U.S. federal jurisdiction, and in various state and foreign jurisdictions. On June 30, 2014, the open statutes of limitations in our significant tax jurisdictions were as follows: federal 2010 through 2013, state 2009 through 2013, and foreign 2007 through 2013. On June 30, 2014, of our gross unrecognized tax benefits of $3.7 million, which included $0.2 million of interest and penalties, $1.5 million are classified as current and $2.2 million are classified as long term.
