[1] (a)The 2013 dismissals reported in the table above include the dismissal of approximately 11 thousand claims that were considered pending inactive claims. No pending inactive claims were dismissed during the six months ended June 30, 2014. Inactive claims represent pending claims in Mississippi filed in 2004 or prior, which have been excluded from our asbestos measurement because the plaintiffs cannot demonstrate a significant compensable loss. As such, management believes these claims have little-to-no value.
