Commitments and Contingencies Disclosure [Abstract]
Significant Change in Unrecognized Tax Benefits is Reasonably Possible	It is reasonably possible that unrecognized tax benefits may decrease by as much as $8 million in the next twelve months, related primarily to state apportionment matters. However, since the tax was fully paid in prior years, the unrecognized tax benefit would be eliminated without impacting expense.

Other information relative to a tax position which it is reasonably possible that the total amount of the unrecognized tax benefit will significantly increase or decrease within twelve months of the balance sheet date.
