Fair Value Disclosures [Abstract]  
Schedule Of Fair Value, Assets and Liabilities Measured on Recurring Basis
The following tables summarize the carrying amounts, fair values and recurring fair value measurements recorded or disclosed as of December 31, 2013 and March 31, 2014, based on the three levels established by ASC 820; Fair Value Measurements and Disclosures. The carrying values of cash and cash equivalents (classified as Level 1) and energy commodity derivatives deposits approximate fair value because of the short-term nature or variable rates of these instruments; therefore, these items are not presented in the following tables (in thousands).
