Taxes [Abstract]
Income Taxes [Text Block]	Income Taxes During the three months ended December 31, 2011, there were no material increases or decreases in unrecognized tax benefits and we do not anticipate any material increases or decreases in the amounts of unrecognized tax benefits over the next twelve months. As of December 31, 2011, we had approximately $198,000 of interest and penalties accrued as tax liabilities on our balance sheet. During the three months ended December 31, 2011, we incurred $1.6 million of foreign income tax expense associated with (i)a $14.8 million deemed capital distribution from our Suncore joint venture which was immediately reinvested back into Suncore and (ii) a cash dividend of $1.6 million from Suncore which was distributed to offset our foreign income tax obligation that was incurred. No tax expense was incurred during the three months ended December 31, 2010. See Footnote 15 - Suncore Joint Venture for additional disclosures related to this foreign income tax expense. We file income tax returns in the U.S. federal, state, and local jurisdictions and, currently, no federal, state, and local income tax returns are under examination. The following tax years remain open to assessment for each of the more significant jurisdictions where we are subject to income taxes: after fiscal year 2007 for U.S. federal, after fiscal year 2006 for the state of California, and after fiscal year 2007 for the state of New Mexico.
