Web users can explore the impact of race/ethnicity and immigration over time. (See Schedule O For continuation)</Desc>

Income tax benefits are recognized for income tax positions taken or expected to be taken in a tax return only when it is determined that the income tax position will more-likelythan-not be sustained upon examination by taxing authorities. PRB has analyzed tax positions taken for filing with the Internal Revenue Service and all state jurisdictions where it operates. PRB believes that income tax filing positions will be sustained upon examination and does not anticipate any adjustments that would result in a material adverse effect on PRB's financial position, results of activities or cash flows. Accordingly, PRB has not recorded any reserves or related accruals for taxes, interest and penalties for uncertain income tax positions at September 30, 2014 and 2013. PRB is open to examination by taxing authorities from 2011 forward. related accruals for taxes, interest and penalties for uncertain income tax positions at September 30, 2014 and 2013.
