Income Taxes [Abstract]
Income Taxes	11. Income Taxes The Company recorded income tax expenses for the three and nine months ended December 31, 2012 and 2011. This is primarily due to the federal and state income tax provision on pretax income in the U.S. and not recognizing income tax benefits related to the net losses of Fenco's Canadian operations for the three and nine months ended December 31, 2012 and 2011 due to the recoverability of these tax benefits not being deemed by the Company to be more likely than not to be realized. In addition, for the three and nine months ended December 31, 2012, the Company recorded $28,000 and $126,000, and for the three and nine months ended December 31, 2011, the Company recorded $141,000 and $281,000, respectively, of income tax expense specifically related to the Fenco subsidiaries located in Mexico, a separate tax jurisdiction. The income tax expenses reflect effective income tax rates of 50.3% and negative 10.0% for the three months ended December 31, 2012 and 2011, respectively. The income tax expenses reflect effective income tax rates of negative 53.6% and negative 18.8% for the nine months ended December 31, 2012 and 2011, respectively. The income tax expenses, excluding the net losses of Fenco's Canadian operations, reflect effective income tax rates of 33.0% and 36.9% for the three and nine months ended December 31, 2012, respectively. The income tax expenses, excluding the net losses of Fenco's Canadian operations, reflect income tax rates of 37.7% and 39.3% for the three and nine months ended December 31, 2011, respectively. The income tax rate for the three months ended December 31, 2012 includes required adjustments to reflect the appropriate nine month rate for fiscal 2013. The income tax rates for all other periods were higher than the federal statutory rates primarily due to state income taxes, which were partially offset by the benefit of lower statutory tax rates in foreign taxing jurisdictions. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various states and foreign jurisdictions with varying statutes of limitations.
