Loss Contingency, Range of Possible Loss	Given the uncertainty related to the ultimate resolution of this case as well as the time period to reach a conclusion, we are unable to provide an estimate of any possible loss. We currently estimate a range of possible outcomes between zero and $111.0 million based on all of the facts presented.  At this time, we cannot determine that any amount within the range is a better estimate and therefore we conclude that we should accrue the minimum of zero as of March 31, 2014. We will continue to evaluate the possible outcomes of this case
