9. Litigation

From time to time, the Company is involved in litigation and other legal proceedings arising out of the ordinary course of its business. On October 15, 2010, a putative securities class action was filed in the United States District Court for the Middle District of Florida. On March 20, 2012, the Court granted the Company's motion to dismiss the complaint for failure to state a claim, and the plaintiff subsequently filed a notice of appeal. While the outcome of any further legal proceeding cannot be predicted with certainty, the Company does not expect these matters to have a material effect on its financial condition or results of operations.
