LossContingencyOpinionOfCounsel | Based on the settlement reached in the 2005 arbitration, we moved for, and the District Court granted us, summary judgment, dismissing all of Capstone’s claims in the 2013 lawsuit. Capstone appealed, and in April, 2016, the 10th Court of Appeals, Waco, Texas Division, reversed the ruling with respect to the indemnity claims and remanded the case back to the District Court. The Texas Supreme Court subsequently denied our petition to review this decision and our motion for rehearing. As a result, we filed a new motion for summary judgment at the District Court level in April 2017. The court denied the motion, and we were consolidated back into the main case. The Company attended mediation on June 23, 2017. Settlement was not reached, and the Company did not commit to any offer at mediation. The Company will defend the claims and expects ultimately to prevail on the merits, but there can be no assurance that the Company will prevail or that it will not incur costs and liability for indemnity in connection with resolution of the claims. To date, the Company has not established a reserve with respect to this matter, as we believe the likelihood of our responsibility for damages is not probable and a potential range of exposure is not reasonably estimable. |
