How have the courts treated the additional contentions of defendants in their reply brief?

Other than their global argument on the applicability of the litigation privilege, defendants offer only brief conclusory statements to challenge the trial court's ruling that plaintiff showed a probability of prevailing on his second cause of action for breach of the implied covenant of good faith and fair dealing. They offer no citations to supporting authority or to the record in either their opening brief or their reply brief with respect to their additional arguments. When an appellant raises a contention, "but fails to support it with reasoned argument and citations to authority, we treat the point as waived." (Badie v. Bank of America (1998) 67 Cal.App.4th 779, 784-785.) Therefore, we treat defendants' additional conclusory contentions as waived.
